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

541 * Makefile.dist (gdb.tar.Z): Create doc subdir w/out CVS/RCS crud.
543 * README: Update for release 3.95.
544 * config.gdb: Don't create readline dir in subdir builds.
545 * main.c: Include with "..." form for non-system include files,
546 so "gcc -MM" for "make depend" works.
547 Include readline files with "...h" rather than <readline/...h>.
548 * mipsread.c: Include "ecoff.h" rather than "intel-coff.h".
550 * coffread.c: Undo minor damage done by Rich Pixley. Use
551 different internal and external representations of COFF
552 data structures. Use new BFD routines for swapping them in and
554 * symfile.c (free_named_symtabs): Avoid freeing file names that
555 are null or empty. Old i960 tools seem to produce files that
556 claim to have empty names, causing each successive file read
557 to blow away the previous one.
558 * sparc-xdep.c (deferred_stores): Repair minor damage by Rich.
559 Move deferred_stores to top of file, but don't separate its
560 #define's from its variable. Add commentary.
561 * Makefile.dist: Fix Rich damage; undo "configure" changes in
562 favor of keeping the (working) config.gdb. Move readline
565 Fri May 17 12:49:56 1991 Per Bothner (via gnu at cygint.cygnus.com)
567 * dbxread.c (read_struct_type): Try to handle g++ version 1 MI
569 * infptrace.c (fetch_registers): no result, since now void.
570 * tconfig/news: target depends on m68k-tdep too.
572 Fri May 17 14:40:14 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
574 * Makefile.dist: added readline/inc-*.texinfo to dependencies for
577 * readline/inc-history.texinfo, readline/inc-readline.texinfo:
578 applied various small fixes due to or inspired by RMS comments
580 * doc/gdb.texinfo: finished using all RMS comments, save those for
581 appendices on readline and cmd history (which are in other source
584 Thu May 16 18:06:05 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
586 * doc/gdb.texinfo: (1) Updated w/ref to RMS comments through
587 chapter 9; (2) documented 'break' command's menu mode for
588 overloaded names, in response to hgs problem report C++ p-31
590 Wed May 15 11:02:48 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
592 * doc/gdb.texinfo: (1) better introductory example; (2) more
593 consistent use of @code, @samp, @file, @kbd throughout; small
594 cleanups to first three nodes; (3) new "Contributors" node;
595 (4) Appendix, Renamed Commands; (5) divert specialized startup
596 instructions to "Targets" chapter for generic manuals, while
597 leaving them up front for manuals specific to specialized
598 environments; (6) apply fixes from RMS comments through chapter 4.
600 * pretex.m4: modify explanatory text slightly (and redefine
601 "regexp") to keep GNU m4 from complaining. (It still crashes
602 later, but one step at a time...)
604 Wed May 15 10:32:12 1991 John Gilmore (gnu at cygint.cygnus.com)
606 * readline/readline.c (update_line): Avoid dereferencing a pointer
607 before comparing it to its bounds. Saber caught this.
608 (init_terminal_io): Don't set BC from the "pc=" termcap variable,
609 and only set PC if tgetstr returned non-null. Saber caught this.
611 Tue May 14 16:29:53 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)
613 * Makefile.dist: put gdb.dvi stuff (updated to use M4 preprocessor
614 stuff for config manual) here where it counts; updated
615 to use new subdir structure (gdb/doc/).
617 * Makefile: generated from above via
621 * gdbint.texinfo: added instructions on generating gdb.info* files
622 locally for release. These are ordinary info
623 files, formatted from gdb.texinfo (via gdb-all.texinfo, see
624 Makefile)---but due to use of texinfo 2, can't count on makeinfo
625 to generate these, so we distribute them already formatted.
627 * gdb.texinfo: included full Info node and menu crud (as generated
628 by C-u M-x texinfo-master-menu using the texinfo-2 elisp code).
630 * Makefile: updated "gdb.dvi" target to use M4 preprocessor;
631 put in comments-for-future gdb.info target (one day makeinfo will
634 Tue May 14 13:51:36 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)
636 * gdb.texinfo: Updated to include new or old undocumented
637 commands, at least the following (perhaps some others I forgot to
638 record): info f, info float, info path, info program, info s, info
639 set, info source, info terminal, info types, info user, set/show
641 Also covered all recent GDB command renames for v4.
643 Mon May 13 14:57:46 1991 John Gilmore (gnu at cygint.cygnus.com)
645 * mipsread.c: Rather than keeping count of how many symtabs
646 and psymtabs we have, for sorting purposes, count them when
647 we need to sort. This fixes bug in rereading of symbol tables.
649 Fri May 10 15:43:33 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)
651 * infcmd.c: renamed "info path" to "show paths"

666 symtab.h, target.c, target.h: Lint.
667 * core.c: setup and select frame after reading shared libs,
668 else reading shared libs will clobber them. Lint.
669 * utils.c (error): Force out any buffered wrap text.
671 Fri May 3 22:01:56 1991 John Gilmore (gnu at cygint.cygnus.com)
673 * remote.c: Remove decls of memory_insert_breakpoint
674 and memory_remove_breakpoint, no longer used. (Suggestion of
677 * Makefile.dist: use ${subdir} in paths of BFD and LIBIBERTY,
678 to make it easier to interface to "configure"'d libraries.
680 Fri May 3 13:10:01 PDT 1991 Roland Pesch (pesch at fowanton.cygnus.com)
682 * valprint.c: introduce "set p", "set pr", "show p" and "show pr" as
683 aliases for set/show print.

1194 (add_target): Call add_cmd and mess with targetlist->doc.
1195 core.c, exec.c, remote-eb.c, remote-nindy.c, remote-vx.c,
1196 remote-vx.68.c, inftarg.c, remote.c: Add doc field to target struct.

1226 command is add-symbols.
1227 * target.c (dummy_target): Permit add_syms_addr_command.
1229 Sat Apr 13 14:46:07 1991 John Gilmore (gnu at cygint.cygnus.com)
1231 Permit symbols to be superseded when new symbol files have
1232 been read in, particularly for VxWorks.
1234 * dbxread.c (read_dbx_symtab): Allow N_SOL to cleanly take us back
1235 to the main file, as well as to include files. Also, put global
1236 functions into the global psymtab, to make "i fun" work.
1237 (end_psymtab): Free named symtabs and psymtabs for a file, once a
1238 new psymtab for it has been read.
1239 * coffread.c (end_psymtab): Free named symtabs and psymtabs for
1240 a file, once a new symtab has been read for it.
1241 * mipsread.c: FIXME. We need to do the same for MIPS, but it
1242 looks harder to determine the top-level block before it's been
1243 queued to the psymtab list.
1245 * symfile.c (symbol_file_add): Use filtered printing and wrap it.
1246 If we have wiped out any old symbol tables, clean up at end of
1248 (symbol_file_command): Don't reference symfile_fns if it's zero.
1250 * symtab.h (GLOBAL_BLOCK, STATIC_BLOCK, FIRST_LOCAL_BLOCK): New
1251 defines for the blocks of a blockvector that contain global and
1252 file-static symbols and the first of the smaller scope contours.
1253 * symtab.c (lookup_symbol, find_pc_symtab, find_pc_line,
1254 decode_line_1, make_symbol_completion_list): Use the above.
1255 * coffread.c (end_symtab, patch_opaque_types): Ditto.
1256 * dbxread.c (end_symtab): Ditto.
1257 * expread.y (block): Ditto.
1258 * mipsread.c (throughout): Ditto.
1259 * symmisc.c (free_named_symtabs): Ditto.
1261 * symtab.c (list_symbols): Process the first symbol of the
1262 static psymbols list.
1263 (types_info): Restore this function from its untimely #if 0.
1264 It's not perfect, but it is better than nothing.
1265 (_initialize_symtab): Restore "info types".
1267 Thu Apr 11 05:23:19 1991 John Gilmore (gnu at cygint.cygnus.com)
1269 * m68k-stub.c: Remote stub for 680x0's, created from
1270 rem-m68k.shar (which is removed).
1271 * nindy-share/{Makefile,Onindy.c,blout.h,env.h,nindy.c,ttyflush.c}:
1272 Remove RCS log stuff now that we use CVS and it blows our diffs.
1274 Wed Apr 10 14:18:06 1991 John Gilmore (gnu at cygint.cygnus.com)
1276 * symmisc.c (free_named_symtab): Make it work, in its current
1277 kludgy fashion. Change result to indicate if we blew away bkpts.
1278 * dbxread.c (end_symtab): Accumulate result from
1279 free_named_symtab and print warning if we blew user's state.
1280 * symfile.h: free_named_symtab now returns an int.
1282 Mon Apr 8 23:57:43 1991 John Gilmore (gnu at cygint.cygnus.com)
1284 * dbxread.c (dbx_symfile_read): Initialize psymbol list if this
1285 is the first symbol read, even if not mainline.
1286 (dbx_psymtab_to_symtab): symfile might be zero, cope.
1287 * exec.c (exec_ops): Add_syms_addr is valid in our tvec.
1288 (set_section_command): New command ("section xxx yyy" -- should
1289 be renamed to "set section xxx yyy" FIXME) which sets the
1290 base address of a section of the exec file, overriding the
1291 virtual address that BFD reports.
1293 Fri Apr 5 17:14:39 1991 John Gilmore (gnu at cygint.cygnus.com)
1295 * exec.c: Add add_syms_addr_command to exec_ops, so you can
1296 load symbols at any address while examining an exec file.
1298 Thu Apr 4 10:09:35 1991 John Gilmore (gnu at cygint.cygnus.com)
1300 * tm-i386v.h (FLOAT_INFO): Don't define it, since the code
1301 for printing the float info is host-dependent, not
1302 target-dependent. FIXME.
1303 * i386-pinsn.c: Move #includes to top, remove useless ones.
1304 * i386-tdep.c: Don't bother including <.../reg.h> since we
1305 don't use it (and it doesn't exist on host systems).
1307 * ieee-float.c (ieee_extended_to_double): Convert NaN to Inf.
1308 Convert negative numbers properly.
1309 (ieee_test): Make numbers really random; fix format arg.
1311 * infcmd.c (attach_command, detach_command): Don't repeat on CR.
1312 * core.c (core_detach): Unpush core_ops, which might not be on
1313 top. We used to just pop the top, which broke things. Don't
1314 need dont_repeat() any more.
1315 (core_file_command): Psst! Don't repeat it.
1316 * remote-nindy.c (nindy_detach): Don't need dont_repeat() now.
1317 * expprint.c (print_subexp): Avoid switch fallthru on
1318 BINOP_ASSIGN_MODIFY, so we can print += and such.
1319 * frame.h: Fix typo.
1320 * inflow.c (kill_command): After killing inferior, print our
1321 current frame in the core file, if we have one.
1322 (generic_mourn_inferior): When inferior dies, either select
1323 the current frame (in the new target, e.g. core file), or
1324 set both the current and selected frames to NULL.
1326 Changes from Peter Schauer.
1328 * infptrace.c: Avoid <sys/ptrace.h> on USG.
1330 * Make all file names fit in 14 characters (sigh and damn!):
1331 mv hp300hpux-xdep.c hp300ux-xdep.c
1332 mv symmetry-xdep.c symm-xdep.c
1333 mv symmetry-tdep.c symm-tdep.c
1334 mv convex-opcode.h convx-opcode.h
1335 mv tm-vxworks960.h tm-vx960.h
1336 mv tm-vxworks68.h tm-vx68.h
1337 mv Makefile.srcdir Makefile.sdir
1338 mv gdb-int.texinfo gdbint.texinfo
1339 mv remote-sa.m68k.shar rem-m68k.shar
1340 mv remote-multi.shar rem-multi.shar
1341 * Makefile.dist, README, config.gdb, convex-pinsn.c,
1342 tconfig/symmetry, tconfig/vxworks960, tconfig/vxworks68,
1343 xconfig/hp300hpux, xconfig/symmetry: Change names to shorter
1346 * command.c (user_info_1, user_info): New command for listing
1347 the user-defined commands.
1349 Wed Apr 3 15:00:26 1991 John Gilmore (gnu at cygint.cygnus.com)
1351 * dbxread.c (really_free_pendings): Clear file_symbols
1352 and global_symbols after freeing them; otherwise, running
1353 this function twice (if it appears twice on the cleanup
1354 chain), we try to free things twice.
1356 * dbxread.c (read_dbx_symtab): Calculate end_of_text_addr
1357 based on text_addr (the address of text in core), not on addr (the
1358 offset between text in the .o file and in core). This change
1359 is from Peter Schauer.
1361 * main.c: Define ALL_CLEANUPS as a cast of zero.
1362 (return_to_top_level): Use it.
1363 (main): Do all cleanups after each command run as part
1364 of the gdb startup sequence. Also do all cleanups before
1365 entering the command loop, and every time we exit the command
1366 loop and reenter. Before, the cleanups from the startup sequence
1367 were being left undone until the first error!
1368 (command_loop): Rename do_nothing cleanup to command_loop_marker
1369 so we can see it easily when examining the cleanup chain.
1370 (init_signals): Add another do_nothing for signal handling.
1371 (quit_command): Only try to kill target if it has execution.
1372 Problems in the target stack got us into a state where
1373 inferior_pid was nonzero but none of the targets had execution.
1374 In this state you couldn't exit gdb.
1376 * dbxread.c: Two changes from Peter Schauer.
1377 (echo_command): Fflush output after an echo command.
1378 (show_history): Pass all args to cmd_show_list.
1380 * utils.c (init_malloc): Call mtrace to turn on tracing
1381 if the environment variable MALLOC_TRACE is set to a file name.
1382 * mtrace.c: Add source file which provides a log of every malloc,
1383 free, and realloc to a trace file.
1384 * mtrace.awk: Add source file which analyzes the trace file.
1385 * Makefile.dist (GNU_MALLOC, MALLOCSRC): Add mtrace.{c,o,awk}.
1386 (VERSION): Roll to 3.94.3.
1388 * breakpoint.c (breakpoint_1): Add a space to "i watch" output.
1389 (check_duplicates): Don't bother with watchpoints.
1390 (set_raw_breakpoint): Comment about danger of this routine.
1391 (watch_command): Parse and eval all args before calling
1394 * solib.c (find_solib): Avoid error in referencing memory to
1395 see if any more shared libraries have been added. This is
1396 particularly useful if the target has terminated. Bug reported
1399 Changes from Peter Schauer <pesrem@regent.e-technik.tu-muenchen.de>
1400 in bringing up 3.94.2 on the Sun-3.
1402 * Makefile.dist: Include CFLAGS in rule for cplus-dem.o.
1403 * breakpoint.c (enable_breakpoint): Check for valid watchpoint
1404 expression (in scope) before reenabling watchpoint.
1405 * signame.c (init_sigs): Add missing declaration of i, fix
1406 sys_siglist declaration.
1407 * source.c (list_command): Fixed range computation to use
1409 * stack.c (backtrace_command): Do not allow command if target has
1410 no stack, print informative error message.
1411 * target.c (target_command): Do not write into command line
1412 because this fails if the target command is used in a user defined
1413 command. [This change was enhanced by gnu to support any-
1414 unique-prefix matching on target names.]
1415 * valops.c (value_struct_elt): Avoid infinite loop on an
1416 erroneous attempt to print the member of function (try p main.p).
1418 Mon Apr 1 17:05:45 1991 John Gilmore (gnu at cygint.cygnus.com)
1420 * expread.y (name_no_typename): Avoid reduce/reduce errors
1421 caused by ambiguity in handling NAME_OR_INT and NAME_OR_UINT.
1422 Since the GDB parser really doesn't use name_no_typename in a
1423 name-only context, the parser can't tell the diff between
1424 names and numbers here. Avoid allowing a name_no_typename
1425 to be a NAME_OR_*INT to resolve the conflict.
1427 Sun Mar 31 20:12:07 1991 John Gilmore (gnu at cygint.cygnus.com)
1429 Bugfixes from Mark Fox (markf@wrs.com) (test=testField.c):
1431 * valprint.c (val_print_fields): bitfield printing didn't handle
1432 byte order. Indirect through a few more fns to cope.
1434 * values.c (modify_field): also cope with byte order.
1436 Sat Mar 23 10:02:21 1991 John Gilmore (gnu at cygint.cygnus.com)
1438 Cleanup for release 3.94.2:
1440 * Makefile.dist: Pull REMOTE_OBS. Fix saber includes for BFD
1441 include files. Roll version to 3.94.2.
1443 * coffread.c (init_stringtab): Read length into unsigned char
1444 array before swapping; don't assume 32-bit longs.
1446 * target.c (target_info): Don't bother with get_sym_file, just use
1447 the symfile global variable.
1448 * symtab.h, symfile.c (get_sym_file): Delete it.
1450 * dbxread.c (dbx_symfile_init): Don't depend on long == 4 bytes.
1451 (define_symbol): Set symbol line number to 0 if not gcc-compiled.
1452 (read_type): Replace one more error() with complain().
1454 * mipsread.c (parse_partial_symbols): Replace printf with complain.
1456 * i960-tdep.c: Fix copyright attribution.
1458 * config.gdb: Quote all backquotes in doublequotes. You can
1459 quote me on that. BSD 4.4 shell found this one.
1461 * infptrace.c (throughout): The third argument to ptrace is an
1464 * infrun.c (wait_for_inferior): When program has terminated, we
1465 have to call target_terminal_ours before we pop that target off
1466 the stack (e.g. before a call to target_kill or
1467 target_mourn_inferior). This fixes problem where a program
1468 terminates, then GDB stops for (tty output) and you have to type
1469 "fg" to the shell to resume it. FIXME: This code for what to
1470 do after termination really should be in normal_stop instead.
1472 * gdbcore.h (read_memory_check): Change declaration; it changed
1475 * terminal.h: Include <sgtty.h> before <sys/ioctl.h>, since in BSD
1476 4.4 prereleases, this avoids a bug in their sgtty compatability
1478 * remote.c: Use terminal.h rather than hand-rolling the same.
1480 * signame.c, signame.h (psignal): Arg is unsigned, not int.
1481 * utils.c (strsave, strstr): Fix arg types.
1482 * valprint.c (val_print): lint
1484 MIPS symbol table support from Per Bothner:
1486 * symfile.c (symtab_fns): Remove initializer table that needs to
1487 be hacked for each new symbol file format supported.
1488 (add_symtab_fns): New function, chains symbol table
1489 handlers into the global list.
1490 (symfile_init): Search this list.
1491 * symfile.h: Add next pointer, declare add_symtab_fns.
1492 * coffread.c (_initialize_coffread): Call add_symtab_fns.
1493 * dbxread.c (_initialize_dbxread): Call add_symtab_fns.
1495 * mipsread.c (psymtab_to_symtab_1): return void instead of (struct
1496 symbol *). Thus, we no longer need the hack to trash
1497 pst->filename. Good, since that hack confused code in symfile.c!
1499 (reorder_symtabs, destroy_all_symtabs): Removed static
1500 all_symtabs, which was used to qsort symtabs in reorder_symtabs.
1501 Instead, the latter now uses a temporary array (stack-allocated
1502 from an obstack, and then freed).
1504 (parse_symbol): Added a hack to fix up BLOCK_{START,END} if they
1505 haven't been set in the outermost stBlock of a procedure. This was
1506 a problem with f77 binaries on Ultrix 4.?.
1508 (new_symtab, new_symbol, new_type): Continue changing code to use
1509 obstacks more and otherwise conform to dbxread internal style.
1510 Made the free_code of symtabs be free_linetable (as in dbxread)
1511 instead of free_contents. This implies memory leaks when reading
1512 a new symbol table, until the conversion is finished. Did change
1513 (struct symbol) and (struct type) to be allocated on the
1514 symbol_obstack. Blocks and blockvectors are among the things
1517 * mipsread.c (parse_partial_symbols, parse_fdr): It hasn't been
1518 tested much, but it solved one problem (reported by Meissner), and
1519 cleans up some other things. The problem happened when an
1520 included file contains actual code (functions) and not just
1521 definitions. The mips coff is a little inconvenient there, since
1522 it may cause a procedure to be mapped to the wrong psymtab.
1524 * mips-tdep.c (heuristic_proc_desc): Minor cleanup.
1525 * mips-xdep.c (fetch_core_registers): Minor cleanup. FIXME,
1526 this will need work for the new core paradigm.
1528 Opcode patches from the net:
1530 * mips-opcode.h: fix incorrect disassembly of the mfc1, cfc1, and
1531 ctc1 instructions. Also, the cvt.d.w and cvt.s.w instructions were
1532 missing altogether - they are added here. From Bruce Bauman.
1533 * mips-opcode.h: The low mask for C0 instructions was too small.
1534 From Garrett Lau. I modified the fix to check the entire 32-bit
1537 * ns32k-opcode.h: Fix opcodes for deiw and deid. From Bruce
1540 Thu Mar 21 12:56:46 1991 John Gilmore (gnu at cygint.cygnus.com)
1542 Roll in changes from Per Bothner (Tue, 25 Sep 90 11:11:04):
1544 * dbxread.c (read_type): Pointer subtraction (value_sub in
1545 valarith.c) sometimes failed because the types of the
1546 pointers being subtracted were not identical.
1547 These differed because dbxread.c was allocating pointer types
1548 using dbx_alloc_type+smash_to_pointer_type instead of
1549 lookup_pointer_type. I failed to find a justification for the
1550 former, so I changed it to use the latter. Similarly, I
1551 replaced smash_to_function_type by lookup_function_type,
1552 and smash_to_reference_type by lookup_reference_type.
1554 * mipsread.c (parse_symbol, upgrade_type, parse_procedure,
1555 _initialize_mipsread): corresponding changes.
1557 * symtab.c (smash_to_{pointer,reference,function}_type): eliminate.
1559 * source.c (mod_path): Do tilde_expand on each component of the path,
1560 rather than on the (list of) paths as a whole.
1561 (print_source_lines): Set first_line_listed in addition to
1562 current_source_symtab and current_source_line. If the source was
1563 not findable, after a "dir" command to fix the problem,
1564 a "list" would get the wrong lines.
1566 While I was there... (gnu):
1568 * dbxread.c (read_type): Change error to complaint.
1570 Thu Mar 21 12:56:46 1991 John Gilmore (gnu at cygint.cygnus.com)
1572 First attempt at detailed understanding of symbol table memory alloc.
1574 * dbxread.c (dbx_symfile_read): Free our string table if we
1575 aren't the mainline. Free the "info" struct since we're done with
1577 (init_psymbol_list): Free any previously allocated psymbol lists.
1578 (): FIXME: Should realloc-down the psymbol lists when done reading
1579 the main symbol file?
1581 * symmisc.c (free_symtab): Free fullname field too.
1583 * xm-hp300hpux.h (USG): #undef then #define so Makefile can -D.
1584 (REGISTER_ADDR): Make result type unsigned int.
1586 * xconfig/{i386*,hp300hpux,altosgas,altos}: All config files that
1587 define REGEX must also define REGEX1 (its dependency).
1589 Tue Mar 19 21:28:57 1991 John Gilmore (gnu at cygint.cygnus.com)
1591 * tconfig/i960: No longer works, points you at vxworks960 or
1594 * xgdb.c, XGDB-README: Remove file. Users can get the much
1596 * Makefile.dist: Remove all trace of xgdb.
1598 * breakpoint.c (breakpoint_1): Pass demangle arg to
1599 print_address_symbolic.
1600 (clear_breakpoints): Remove unused function.
1601 (breakpoint_re_set_one): Guts of breakpoint_re_set.
1602 (breakpoint_re_set): Use catch_errors to do them all anyway.
1604 * gdb-int.texinfo (Host versus Target): Add section on what is
1605 a "host" feature versus what is a "target" feature.
1607 * infcmd.c (path_command, path_info): Handle the PATH variable
1608 (object search path) as conveniently as the source search path.
1609 * environ.c (set_in_environ): Set some vars in GDB's environment,
1610 in addition to the child's. PATH, G960BASE, G960BIN for starters.
1611 * source.c (mod_path): New function, from guts of
1612 directory_command, modifies a path. Used by path_command.
1613 (directory_command): Call it.
1614 * defs.h (strsave): Declare.
1616 * utils.c (sevenbit_strings): Add new printing option.
1617 (printchar): Use it.
1618 (strsave): Provide this handy helper routine.
1619 (set_width_command): Rename set_screen_width_command.
1620 (_initialize_utils): "set screen-width" => "set width";
1621 "set screen-height" => "set height"; add sevenbit-strings.
1623 * infcmd.c (do_registers_info): Print floating point registers
1624 in raw hex as well as float format, regardless of whether it is
1625 a "virtual" convertible register.
1626 * tm-sparc.h (PRINT_REGISTER_HOOK): Print every pair of float
1627 regs as a double, just in case it's being used that way.
1628 * values.c (unpack_long): Comment on array/function coercion.
1629 (unpack_double): Argument is in target byte order now. For
1630 integer arguments, just call unpack_long and float the result.
1631 * m68k-tdep.c: include defs.h for "const" handling.
1632 * remote-nindy.c: Use ieee-float stuff.
1633 (nindy_fetch_registers): Unpack double regs to host double, then
1635 (nindy_store_registers): Pack extendeds to host double, flip
1636 around by misusing unpack_double, send as target double.
1638 * tm-vxworks68.h (FRAME_CHAIN): Handle current frame pointer of
1639 zero, as when stopped at the first instruction of a process.
1641 * blockframe.c: Fix filename in comment (param.h => tm.h).
1642 * sparc-tdep.c (skip_prologue): More explicit nudging comments.
1643 * tm-68k.h: Fix typos.
1645 Fri Mar 15 01:09:34 1991 John Gilmore (gnu at cygint.cygnus.com)
1647 Changes from a bringup on the DEC Vax under Ultrix 4.0.
1649 * coredep.c (fetch_core_registers): Pass end-address of register
1650 section to register_addr as expected. Don't call supply_register
1651 if we'd just pass it garbage.
1653 * dbxread.c (read_dbx_symtab): Skip N_NSYMS on Ultrix.
1655 * exec.c (xfer_memory): Use boolean xfer_fn result, not int.
1657 * target.c (push_target, target_info): Cast enums to int for < or
1660 * stack.c (print_frame_info): Identify source file & line
1661 even if we can't print it.
1663 * xm-vax.h (MISSING_VPRINTF): No longer missing in Ultrix V4.0.
1665 Sat Mar 9 10:08:20 1991 John Gilmore (gnu at cygint.cygnus.com)
1667 Clean up IEEE floating point support.
1669 * ieee-float.h: New file.
1670 * ieee-float.c: Write real routines to convert between host
1671 doubles and various target IEEE extendeds.
1672 * m68k-xdep.c: Eliminate assembler code for extended floats.
1673 * xconfig/{3b1,altos,altosgas,hp300bsd,isi,news,news1000,sun2os3,
1674 sun2os4,sun3,sun3os3,sun3os4}: Eliminate use of m68k-xdep.o.
1675 * tm-i960.h, tm-68k.h (REGISTER_CONVERT_TO_VIRTUAL,
1676 REGISTER_CONVERT_TO_RAW): Use ieee_extended_to_double and
1677 double_to_ieee_extended.
1678 * i960-tdep.c: Define ext_format_i960.
1679 * m68k-tdep.c: Define ext_format_68881.
1680 * sparc-tdep.c: Define ext_format_sparc, though unused.
1681 * Makefile.dist (HFILES): Add ieee-float.h.
1682 * inftarg.c: #include "ieee-float.h" for the REGISTER_CONVERT
1685 Obsolete the "coffstrip" program in favor of using BFD's strip.
1687 * nindy-share/coffstrip.c: Remove file.
1688 * nindy-share/nindy.c (coffstrip): Routine to run bfd_strip.
1689 * Makefile.dist: Remove references to nindy-share/coffstrip.c.
1690 * tconfig/nindy960: Remove reference to coffstrip.o.
1692 * Makefile.dist: Roll version number to 3.94.1 (not yet final).
1694 Wed Mar 6 09:56:45 1991 John Gilmore (gnu at cygint.cygnus.com)
1696 * symfile.h: Add symfile_bfd, common between dbxread and coffread.
1697 * dbxread.c: Remove static symfile_bfd.
1698 * infcmd.c (do_registers_info): Add PRINT_REGISTER_HOOK, though
1700 * inftarg.c (child_detach): Pop the child_ops vector if the
1701 detach is successful.
1702 * remote-nindy.c (nindy_create_inferior): Don't push a new
1703 nindy_ops since nindy uses the same one for execution and memory
1705 * core.c (core_ops): Use child_attach and child_create_inferior
1706 rather than default attach and create_inferior functions.
1708 Handle floating point registers in core files.
1710 * sparc-xdep.c (fetch_core_registers): Rewrite for float support.
1711 * sun3-xdep.c (fetch_core_registers): Rewrite for float support.
1712 This version untested since BFD doesn't yet support sun3 core
1714 * hp300hpux-xdep.c: Rewrite fetch_core_registers to new calling
1715 conventions. Fix comments and style. This version has not
1716 been compiled yet, since we have no HP inhouse.
1717 * core.c (get_core_registers): Look for two sections, ".reg"
1718 and ".reg2", and pass both to fetch_core_registers sequentially.
1720 Revise directory path yet again.
1722 * source.c (forget_cached_source_info): Not static any more.
1723 (init_source_path): New default source path is "$cdir:$cwd".
1724 (dir_command): Handle variable arguments ($cdir, $cwd).
1725 (source_info): Print "Compilation directory" rather than
1726 "Originally compiled in" to remind people of $cdir.
1727 (openp): If the path contains $cwd, use current directory.
1728 (open_source_file): If compilation directory is known, replace
1729 first $cdir in path with the compilation directory.
1730 (print_source_lines): Even if we can't print the lines, set the
1731 current symtab and line for future commands like "info source" or
1732 "breakpoint". Also, error message now contains the file name,
1733 line number, and file access error message.
1734 (_initialize_source): Fix help text to describe changes.
1735 * main.c (cd_command): Forget cached source info when we chdir.
1736 * utils.c (strstr): Add simple implementation.
1738 Tue Mar 5 01:41:40 1991 John Gilmore (gnu at fowanton.cygnus.com)
1740 * coffread.c (read_one_sym, init_linetable, init_stringtab):
1741 Byte-swap COFF symbol tables if necessary when reading them in.
1742 Use complain() to replace error message in one spot. Needs
1743 corresponding change in bfd/coff-code.h to make some symbol
1744 swapping routines non-static.
1746 Mon Mar 4 00:53:40 1991 John Gilmore (gnu at cygint.cygnus.com)
1748 Merge changes from Eirik Fuller, for UTek.
1750 * defs.h (errno): Add declaration.
1751 * altos-xdep.c, arm-xdep.c, convex-xdep.c, gould-xdep.c,
1752 hp300hpux-xdep.c, infrun.c, inflow.c, infptrace.c, i386-tdep.c,
1753 i386-xdep.c, pyr-xdep.c, mips-xdep.c, remote-eb.c, remote-nindy.c,
1754 remote-vx.c, source.c, standalone.c, stuff.c, sun386-xdep.c,
1755 symmetry-tdep.c, symmetry-xdep.c, umax-xdep.c, utils.c: Eliminate
1756 declarations of errno.
1758 * remote-eb.c: Define B19200 and B38400 as EXTA and EXTB.
1760 * remote-vx.c: Include <sys/time.h> for UTek; Sun gets it via
1761 <rpc/rpc.h> and <rpc/types.h>.
1763 Sat Mar 2 15:47:55 1991 John Gilmore (gnu at cygint.cygnus.com)
1765 * i960-tdep.c (examine_prologue): Add new argument limit,
1766 which stops the scan at the end of the prologue, or at the PC.
1767 This fixes a problem where it walks down into the code for the
1768 user's statements if that code looks like function prologues.
1769 Mark Fox and I have been bouncing this code back and forth, making
1770 small changes to it. Callers changed to match.
1772 Tue Feb 26 01:47:07 1991 Cygnus John Gilmore (cygnus at yuba)
1774 Cleanup for gdb-3.94 release final:
1776 * Makefile.dist: Remove remote-vx.c, remote-nindy.c, and all
1777 the .c files from vx-share and nindy-share, from the various
1778 macros, since they are not found via ALLDEPFILES.
1779 (SFILES): Add tm-i960.h.
1780 (alldeps.mak rule): Break out ALLDEPFILES_MAINDIR and
1781 ALLDEPFILES_SUBDIR. List all the nindy and vxworks subdir files
1783 (TAGFILES_MAINDIR): Change ALLDEPFILES to ALLDEPFILES_MAINDIR.
1784 (gdb.tar.Z): Use ALLDEPFILES_SUBDIR as well as SFILES_SUBDIR.
1786 Mon Feb 25 16:02:35 1991 Cygnus John Gilmore (cygnus at oldman)
1788 * am29k-tdep.c: Add contribution line.
1789 (examine_prologue): Cache information about function prologues in
1790 the misc-function-vector to avoid lots of references over the
1791 serial line while examining instructions.
1793 * core.c (core_close): New function made from cleanup_core.
1795 * core.c, exec.c, inftarg.c, remote-eb.c, remote-nindy.c,
1796 remote-vx.c, remote.c, target.c, target.h,
1797 Update target_ops vector to add attach, close, and load entries.
1798 Use add_syms_addr_command, not add_file_addr_command, for
1799 add_file. Break out close routine from existing code.
1801 * dbxread.c (really_free_pendings): Don't free pending_blocks;
1802 they are in an obstack.
1803 (read_dbx_symtab): Relocate end_of_text_addr in the psymtab.
1805 (define_symbol): Add symbol type parameter; change callers;
1806 pass type parameter to DBX_PARM_SYMBOL_CLASS macro to allow
1807 it to influence the symbol class on the i960.
1808 (define_symbol): Swap LOC_CONST's into target byte order.
1810 * exec.c (exec_close): New function.
1811 (exec_file_command): Call it.
1813 * findvar.c (read_relative_register_raw_bytes): Doc byte order,
1814 Fix byte order of frame pointer.
1815 (read_var_value): Result of 0 if var's value can't be found,
1816 e.g. missing FRAME_ARGS_ADDRESS. Byte-swap LOC_CONST and
1817 LOC_LABEL values to target order. Add LOC_LOCAL_ARG.
1818 (locate_var_value): Use read_var_value and use its lazy address
1819 as the location of the var's value. Lint.
1821 * i960-pinsn.c (next_insn): Add routine from vxgdb for scanning
1824 * i960-tdep.c (arg_address, i960_frame_find_saved_regs): Remove
1825 obsolete Intel versions in favor of vxgdb versions.
1826 (check_host, byteswap, byteswap_val, reorder_val): Eliminate
1827 code dealing with byte order of values, which Intel did in host byte
1828 order rather than gdb-4's target byte order.
1829 (i960_frame_chain_valid): Move to nindy-tdep.c.
1830 (examine_prologue, skip_prologue, frame_find_saved_regs,
1831 frame_args_address, leafproc_return, saved_pc_after_call,
1832 pop_frame): Add vxgdb versions from Mark Fox.
1833 (examine_prologue, frame_struct_result_address): Add code
1834 to deal with the saved value of G13 (struct return address
1836 (frame_args_address): Modify Mark's version to prefer the
1837 saved value over the current value in the topmost frame.
1838 Cache result in the frame info to avoid performance hair in
1840 (print_fault): Add gdb960 code for printing faults.
1841 (_initialize_i960): Actually call check_host.
1843 * ieee-float.c (ieee_extended_to_double, ieee_double_to_extended):
1844 add stub routines. FIXME, these currently just return zero!
1846 * infcmd.c (program_info): Use PRINT_RANDOM_SIGNAL.
1847 (attach_command): Call target_attach, not target_open, now.
1849 * infrun.c (normal_stop): Make global, not static, for vx_attach.
1850 (child_attach): Rename from child_open.
1851 (wait_for_inferior): Use PRINT_RANDOM_SIGNAL. If stop_pc is zero,
1852 don't confuse it with a zero step_resume_break_address.
1854 * inftarg.c (child_detach): Eliminate inferior_pid test.
1855 (child_files_info): Clean up message a bit.
1856 (child_ops): Use child_attach, not child_open, to attach.
1858 * mem-break.c: #ifdef out the whole file if BREAKPOINT is not
1859 set (e.g. on VxWorks or NINDY). Move read_memory_nobpt from
1860 findvar.c to here, since it depends on the contents of the
1861 shadow_contents of breakpoints, but keep if #if 0 since it is
1864 * nindy-tdep.c: New file, contains nindy_frame_chain_valid, moved
1867 * printcmd.c (address_info): Handle LOC_LOCAL_ARG. Lint.
1868 (ptype_command, display_command): Eliminate have_inferior_p and
1869 have_core_file_p in favor of target_has_stack or
1870 target_has_execution.
1871 (print_frame_args): Handle LOC_LOCAL_ARG. Eliminate duplicate
1872 code for actually finding the values of arguments, though we still
1873 keep track of the maximum stack offset for use in printing unnamed
1874 arguments. Handle missing FRAME_ARGS_ADDRESS.
1876 * remote-nindy.c (i960_print_fault): Move to i960-tdep.c.
1877 (struct nindy_regs): Define registers passed to/from nindy.
1878 (nindy_fetch_registers, nindy_store-registers): Translate between
1879 nindy and GDB formats for the registers.
1880 (dcache_init): Statically allocate the cache, since it was being
1881 allocated by a malloc that was never freed anyway.
1882 (nindy_create_inferior): Error, not core dump, if no exec file.
1883 (nindy_before_main_loop): Use target_load, not target_add_file.
1885 * remote-vx.c (net_load): Specify large timeout for load
1886 requests. Allow user to break out with INTERRUPT.
1887 (net_break): Remove useless code, clean up. Change callers.
1888 (parse-args, skip_white_space, find_white_space): Clean up arg
1889 parsing to cope with quoted strings.
1890 (net_wait, net_quit): Never call error, just return status.
1891 (vx_read_register, vx_write_register): Cleanup status checking.
1892 #ifdef the code based on which CPU we are using (960 or 68k),
1893 FIXME, this should be completely general but it isn't yet.
1894 (vx_xfer_memory, vx_resume): Cleanup status checking.
1895 (vx_run_files_info): Improve message.
1896 (vx_load_command): Renamed from vx_add_file_command. Allow load
1898 (net_ptrace): Remove unused routine.
1899 (vx_wait): Adopt code from vxgdb960 to cope with broken
1900 connections to target machine and prompt to disconnect. Remove
1901 debug printouts. Map some EVENT_'s to SIGnals.
1902 (add_symbol_stub, vx_open): Print names of object files we found,
1903 and "ok" if we read their symbols OK. Clarify output in general.
1904 (vx_attach, vx_detach, vx_kill): Add these commands.
1905 (vx_convert_from_virtual, vx_convert_to_virtual): Simplify.
1906 (vx_run_ops): Turn off all_mem, to avoid spurious msg in the
1907 "info files" output, and create_inferior, since we already have
1910 * stack.c (frame_info): Replace Frame_unknown with 0.
1911 (print_frame_arg_vars): Handle LOC_LOCAL_ARG.
1912 (return_command): Pop until the PC matches as well as the FP,
1913 so it works even if the FP is shared with another function,
1914 as in "frameless" or "leaf" procedures.
1916 * symfile.c (load_command): renamed from add_file_target_command.
1917 (add_syms_addr_command): renamed from add_file_addr_command.
1918 (add_syms_command): Stub to call target_add_syms.
1919 (_initialize_symfile): Change command names and descriptions,
1920 add-file => add-syms, and load from alias to its own command.
1922 * target.c (kill_or_be_killed, maybe_kill_then_attach,
1923 maybe_kill_then_create_inferior): Default for attempts to start
1924 a process, if one is already running, is to ask about killing
1925 it and retry if yes.
1926 (upstack_create_inferior): #if-0 it, strata obsolete it.
1927 (push_target, unpush_target, pop_target): to_close() a target
1928 before unstacking it.
1929 (target_info): Renamed from target_files_info.
1930 (_initialize_targets): Rename "i files" as "i target", accessible
1933 * target.h: Improve comments about the target_ vectored routines.
1935 * tm-i960.h: Remove NINDY-specific stuff to tm-nindy960.h.
1936 Convert commenting style to standard GNU style.
1937 (DBX_PARM_SYMBOL_CLASS): allow LOC_LOCAL_ARG's to be recognized.
1938 (SKIP_PROLOGUE): No longer a no-op.
1939 (SAVED_PC_AFTER_CALL): Now handles leaf procedures.
1940 (*_REGNUM): Sort register numbers.
1941 (REGISTER_BYTES, REGISTER_BYTE, REGISTER_RAW_SIZE,
1942 MAX_REGISTER_RAW_SIZE, REGISTER_CONVERTIBLE,
1943 REGISTER_CONVERT_TO_VIRTUAL, REGISTER_CONVERT_TO_RAW): Float regs
1944 are now 10 byte extendeds, not 8 byte doubles.
1945 (FRAME_CHAIN_VALID): Make this config-dependent, since it differs
1946 for nindy versus vxworks targets. FIXME, this should possibly go
1947 in the target vector.
1948 (EXTRA_FRAME_INFO, INIT_EXTRA_FRAME_INFO): Cache both
1949 frame_saved_regs and arg pointer with each frame.
1950 (FRAMELESS_FUNCTION_INVOCATION): New leafproc support.
1951 (FRAME_ARGS_ADDRESS): Use cached result.
1952 (FRAME_ARGS_ADDRESS_CORRECT): New, avoids g14 guessing.
1953 (FRAME_FIND_SAVED_REGS): Change arg to subsidiary fn.
1954 (PRINT_RAMDON_SIGNAL): Call print_fault.
1955 (POP_FRAME): Now works.
1957 * tm-nindy960.h: Break this off tm-i960.h. NINDY-specific
1958 option parsing and startup; STACK_END_ADDR, FRAME_CHAIN_VALID,
1959 BREAKPOINT, and DECR_PC_AFTER_BREAK are here.
1960 (ADDITIONAL_OPTION_HANDLER): use target_load, not
1963 * tm-vxworks960.h: Break this off tm-i960.h. VxGDB specific
1964 startup; DECR_PC_AFTER_BREAK, and FRAME_CHAIN_VALID are here.
1966 * valarith.c (value_subscripted_rvalue): Avoid handling
1967 floats and doubles specially; it gave alignment errors. Lint.
1969 * valops.c (value_of_variable, value_of_this): Error if unknown
1972 * valprint.c (print_floating): Bcopy rather than pointer-deref,
1973 to avoid alignment problems.
1974 (value_print): Handle unknown value address.
1975 (cplus_val_print): Two args are ignored; remove them. Change caller.
1976 (val_print): Use unpack_long rather than pointer-deref.
1979 (unpack_long, unpack_double): Use bcopy rather than pointer-deref
1980 to avoid alignment problems.
1981 (value_being_returned): Error if return value unknown.
1982 (set_return_value): Add bogosity warning, FIXME. *
1984 * TODO: A woman's work is never done.
1986 * Makefile.dist: Distribute REMOTE_OBS into tconfig files.
1987 Separate INCLUDE_CFLAGS for use with lint. Add LINTFILES.
1988 Add ieee-float.o to OBS.
1989 * tconfig/{nindy960,vxworks68,vxworks960}: Include the desired
1990 REMOTE_OBS remote-interface files in the TDEPFILES and TM_FILE.
1991 * tconfig/i960: FIXME. Half-merge, produce warning if config'd.
1993 Changes to generalize the VxWorks RPC protocol slightly, to handle
1994 i960 as well as 68000.
1996 * vx-share/dbgRpcLib.h (VX_SOURCE_STEP): Add.
1997 * vx-share/reg.h: Produce i960 regs #ifdef I80960
1998 * vx-share/xdr_ptrace.c: Skip FPA registers if 960.
1999 * vx-share/xdr_rdb.h: Add SOURCE_STEP struct and xdr decl.
2000 * vx-share/xdr_rdb.c: Add xdr_SOURCE_STEP routine.
2001 * vx-share/xdr_regs.c: Add xdr_regs, xdr_fp_status, xdr_ext_fp
2002 for i960. Change xdr_vectors to xdr_opaques for 68k registers,
2003 so they will move in target byte order rather than network
2004 byte order (happens to be the same).
2006 Mon Feb 25 03:41:44 1991 John Gilmore (gnu at cygint.cygnus.com)
2008 * tm-convex.h (END_OF_TEXT_DEFAULT): Remove #if 0'd block.
2010 Sun Feb 24 00:55:53 1991 John Gilmore (gnu at cygint.cygnus.com)
2013 Add contribution lines to various files, showing where they
2016 * breakpoint.c (break_insn, check_break_insn_size,
2017 read_memory_nobpt): Remove to mem-break.c.
2019 * xm-*.h, param-no-tm.h, tm-29k.h, valprint.c: Change BYTE_ORDER to
2022 * tm-29k.h (STAB_REG_TO_REGNUM): Warn user if symbol table
2023 entry has bad register number. This change is not
2024 tested in this release, FIXME.
2026 * frame.h: Eliminate Frame_unknown in favor of a simple zero.
2029 * value.h: Force value's contents field to be aligned to hold
2030 at least a double or a long long (if supported). This avoids
2031 doing bcopy's in and out of the contents field.
2033 (step_1): Avoid coredump under obscure circumstances when we
2036 * symtab.h (misc_info): Add field to misc function vector for
2037 any kind of cached information the target code desires. AMD
2038 29000 uses this to avoid repeating examine_function_prologue's.
2040 * coffread.c: Lint. Remove static symfile, read_section_header.
2041 core.c (have_core_file_p): Lint: remove.
2042 expprint.c (print_subexp): Lint.
2043 infptrace.c, valops.c, valprint.c: lint.
2045 Roll in changes from vxgdb-5.0.1:
2047 * symtab.h: Comment byte order of each address class. Add
2048 LOC_LOCAL_ARG for frame-relative args (960).
2049 expread.y: Use LOC_LOCAL_ARG where LOC_ARG is used.
2050 symtab.c, symmisc.c: ditto.
2052 * infrun.c (init_wait_for_inferior): Clear stop_signal.
2054 * remote.c (remote_resume): Error if resume with a signal.
2056 * symfile.c (prim_record_misc_function): Clear misc_info.
2057 (fill_in_vptr_fieldno): Check stub type of arg.
2059 * valops.c (value_cast): Avoid looking up names of types whose
2060 name we don't know, to prevent coredump. Sun CC produces typedef
2061 rtx and the name of *rtx is zero...
2063 Mon Feb 18 21:16:25 1991 John Gilmore (gnu at cygint.cygnus.com)
2065 Roll in changes from final AMD 29000 port (Tiemann).
2067 tconfig/am29k: Add COFF_ENCAPSULATE and TARGET=TARGET_AM29K
2068 for ../include/a.out.encap.h. This might not work now that BFD
2069 is separately compiled. Instead, BFD support for encap will have
2070 to translate machine type 29k into the right COFF_MAGIC.
2072 * infcmd.c: Remove references to inferior_pid that aren't used
2073 in actual ptrace calls; use target_has_execution, etc.
2074 (have_inferior_p): Remove function.
2075 (program_info): Print target info rather than "process number";
2076 avoid gratuitous messages unless from_tty.
2077 (run_stack_dummy, finish_command): Set proceed_to_finish.
2078 infrun.c: Remove inferior_pid refs. Decl & init proceed_to_finish.
2079 main.c: Lint. Lose have_inferior_p().
2080 inferior.h (have_inferior_p): Remove, lint.
2081 (proceed_to_finish): Add flag to ask that all regs be saved
2082 by normal_stop, for the few commands that need it, speeding up
2083 serial I/O. Add comments to stop_registers.
2085 * remote-eb.c: Remove newline from breakpoint message we grep
2086 for. Never time out when running the user program.
2090 Wed Feb 13 15:34:40 1991 John Gilmore (gnu at cygint.cygnus.com)
2092 Roll in changes from vxgdb-5.0.1:
2094 * dbxread.c (read_dbx_symtab): If we encounter a "FORTRAN COMMON"
2095 symbol in its raw form, we are processing an unlinked ".o" file.
2096 See if the target environment has assigned it an address, using
2097 target_lookup_symbol (VxWorks does), and enter it into the symtab
2100 * tm-vxworks.h (FRAME_CHAIN, FRAME_CHAIN_VALID): Override usual
2101 68k versions for a simpler version that assumes zero FP at bottom.
2102 Fixes bug of truncated stack reports.
2104 * target.h (target_lookup_symbol): Define this routine's args
2105 and result, finally.
2107 * target.c (nosymbol): Default routine for target_lookup_symbol.
2108 (target_default): Default lookup_symbol and call_function too.
2109 (files_info): Only print has_all_memory warning if a non-dummy
2112 * remote-vx.c (vx_read_register, vx_convert_to_virtual,
2113 vx_convert_from_virtual): If target does not have floating point,
2114 zero register "values", and avoid doing cross-net conversions.
2115 (vx_lookup_symbol): Rename net_lookup_symbol, add to vectors.
2116 (vx_open): Rearrange code that attaches to target and reads
2117 symbols for all loaded modules, to work if some of the modules
2118 are not accessible. Add symbol_stub() and add_symbol_stub()
2119 as callbacks from catch_errors(). Allow connect attempt to be
2120 interrupted painlessly with ^C (FIXME, there are still some bugs
2121 if the interrupt happens during symbol reading.). Print
2122 final message with puts_filtered, since symbol messages are
2127 * main.c (catch_errors): Only print errstring if non-null.
2128 (command_loop): Avoid an ioctl per command to test ISATTY.
2130 * remote-vx.c (net_load): make static; avoid sophomoric msg.
2131 (vx_xfer_memory): Return correct result!
2132 (vx_files_info): Indicate whether target has float or not.
2133 (vx_lookup_symbol): Complain, not error, if target gone.
2134 (vx_open): Print "Connected" msg before disabling immediate-quit.
2135 [FIXME: lookup_symbol and vx_open changes need testing.]
2137 target.c, remote-eb.c, inftarg.c, am29k-opcode.h, target.h,
2138 tm-29k.h, tmm-vxworks68.h, symfile.c, gdb-int.texinfo: Add
2139 contributor lines and update copyrights to 1991.
2141 Changes from an attempted H-PUX host port:
2143 * infptrace.c (PT_ATTACH, PT_DETACH): Handle HP/UX, which
2144 defines PT_ATTACH and PT_DETACH but not PT_KILL.
2145 * remote-eb.c (eb_open): Misplaced endif kills sysv H/PUX.
2146 * remote-vx.c: include <sys/time.h> for HPUX.
2147 * hp300hpux-xdep.c (fetch_core_registers): Rewrite old
2148 "core_file_command" routine to BFD regime. May not work yet.
2150 Attempted port of "gdb-3.4 Van Jacobson xgdb" to modern gdb.
2152 * xgdb.c: Replace X10 version with some VJ version.
2153 (FIXME: Its copyright assignment is not on record.)
2154 * xgdb.c: Update include files to X11R4 (Xaw crud).
2155 (xgdb_display_source, create_text_widget): fix call to
2156 get_filename_and_charpos. Rewack source window stuff for X11R4
2157 (gleaned from include files, and "nm's" of binary libraries, since
2158 I had no doc available).
2159 (append_selection, append_selection_word): Disable with FIXME
2160 since R4 changed interface here.
2161 (create_buttons): Add back the old set of buttons.
2162 (xgdb_create_window): Fix call to XtInitialize (&argc not argc).
2164 * Makefile.dist (xgdb, xgdb-init.c): Update for X11R4 on Suns.
2165 Roll VERSION to 3.94 (not yet final though).
2167 Sat Feb 9 09:46:25 1991 John Gilmore (gnu at cygint.cygnus.com)
2169 * obstack.h (obstack_ptr_grow, obstack_ptr_grow_fast,
2170 obstack_int_grow, obstack_int_grow_fast): Eliminate
2171 cast on left of assignment, which gives MIPS cc fits and is
2174 * sparc-pinsn.c (print_insn): Eliminate 'set' test, subsumed by
2175 F_ALIAS. Use printf, not fprintf, when not passing a file
2177 (compare_opcodes): Check that identical instructions have
2178 identical opcodes, complain otherwise.
2180 * sparc-opcode.h (st %fsr): Fix opcode "lose" mask. This
2181 was reported by Roland McGrath.
2182 (unimp): Only match if exactly zero instruction. (Roland)
2183 (branches and traps): Generate all variations of these
2184 instructions with macros, based on a single call that defines
2185 each condition name and its binary representation.
2186 (set): Turn on alias bit, to avoid test in sparc-pinsn.c.
2188 * valprint.c (val_print_fields): Take, and use, format parameter.
2189 This means that "p/x struct" again prints the elements in the
2190 desired format. Changed callers.
2192 * stack.c (frame_info): Use filtered output, and indicate wrap
2193 points. Remove kludgy formatting designed to avoid line wrap.
2195 * utils.c (wrap_here): If the line is already full (because
2196 we had printed a long indent or long wrapped string), do an
2197 immediate newline-and-indent.
2199 * m68k-pinsn.c (print_insn_arg): Bugfix from
2200 ntmtv!thompson@ames.arc.nasa.gov (Mike Thompson): 'bkpt #0'
2201 instruction is incorrectly disassembled as bkpt #8.
2203 * dbxread.c (end_psymtab): Bugfix from Peter Schauer
2204 <pesrem@regent.e-technik.tu-muenchen.de>: If you want to set a
2205 breakpoint in a *.y file gdb will say Reading in symbols for *.y...
2206 and then will dump core (sometimes). I traced it back to an
2207 uninitialized symfile_name in psymtab_to_symtab.
2208 (const_vol_complaint): Add quotes to message.
2209 (define_symbol): Only believe line number if gcc_compiled.
2210 Avoid allocating symbol if we will not return it.
2212 Add target strata support so that newly established targets go
2213 into their right place in the target stack (e.g. a new exec file
2214 doesn't wipe out the ability to access the running process).
2216 * target.h, core.c, exec.c, inftarg.c, remote-eb.c,
2217 remote-nindy.c, remote-vx.c, remote.c, target.c: Add to_stratum
2218 and initialize it properly in all the targets.
2220 * target.h: Document strata. Change return type of push_target.
2222 * target.c (nomemory): new function for dummy memory access.
2223 (tcomplain): Rename complain, now also used in symfile.c.
2224 (push_target): Push targets within strata. New return value shows
2225 whether new target is on top of stack or not. Always keep dummy
2227 (target_files_info): Ignore dummy target.
2229 * core.c (core_open): Warn user, and skip accessing file, if the
2230 core target is not the topmost target in the stack.
2231 * remote-nindy.c (nindy_create_inferior): Avoid unpush_target, now
2234 * remote-vx.c: Remove vx_prepare_to_store from vxworks memory
2235 target_ops, it doesn't belong there since we have no regs there.
2236 Change name of target from machine => memory to clarify.
2238 Thu Feb 7 16:32:09 1991 John Gilmore (gnu at spiff.cygnus.com)
2240 * Freeze version 3.93 for release.
2242 * Makefile.dist: Handle vx-share and nindy-share subdirs
2243 properly when building gdb.tar.Z.
2245 * symtab.c: lint; add no_symtab_msg to consolidate the messages
2246 printed in various places, so I could change just one copy.
2248 * dbxread.c, coffread.c: Change references to bfd->iostream
2249 to cast to FILE *, now that BFD avoids needing types defined
2250 in other header files.
2252 Tue Feb 5 21:39:35 1991 John Gilmore (gnu at cygint.cygnus.com)
2254 * command.c, dbxread.c, expprint.c, infcmd.c, infptrace.c,
2255 infrun.c, printcmd.c, remote-nindy.c, source.c, sparc-tdep.c,
2256 sparc-xdep.c, symfile.h, symmisc.c, utils.c, valprint.c: Lint
2257 (actually gcc -Wall).
2259 * dbxread.c: Remove first_global_sym, last_global_sym, since
2260 they are never referenced.
2262 * defs.h (baud_rate): Declare.
2263 main.c: Define it, and add the -b option to set it.
2265 * gdb-int.texinfo: Add text on how to define a new host or target
2266 architecture, prompted by Per Bothner's questions about MIPS
2269 * gdb.texinfo: Document "complaints". Change doc of -q since
2270 gdb no longer prints the copyright and blurb if you specify a file
2271 name to be debugged (just like Emacs). Add doc for Nindy-specific
2272 command line flags for specifying target serial port and such.
2273 Update copyright to 1991.
2275 * gdbcore.h: Remove a large mass of now-useless crud, since BFD
2276 has taken over for us the job of ripping up executable files. The
2277 crud caused Per Bothner's port to not compile.
2279 * infrun.c (normal_stop): Avoid printing "Program exited
2280 normally" if we are in batch mode. This allows a GDB which
2281 executes a program on a target system, to behave like a Unix
2282 command (input from stdin, output to stdout, no extraneous
2285 * main.c (main): Allow additional machine-dependent command line
2286 options to be specified with the ADDITIONAL_OPTIONS,
2287 ADDITIONAL_OPTION_CASES, ADDITIONAL_OPTION_HELP, and
2288 ADDITIONAL_OPTION_HANDLER macros. Also allow machine-dependent
2289 processing to occur just before the main loop with
2290 BEFORE_MAIN_LOOP_HOOK.
2291 (main): If a "core file" argument is specified, and it is not a
2292 core file, try it as a process ID to attach.
2293 (symbol_completion_function): Attempt to cope with
2294 "show screen-" TAB, not very successfully. This needs more work,
2296 (batch_file): New function, returns whether we are reading
2297 commands from an interactive tty on stdin, or from somewhere else.
2298 Called by normal_stop since it doesn't get from_tty passed down
2299 to it like many commands do.
2301 * remote-nindy.c: Handle command line options for nindy
2303 (nindy_before_main_loop): Prompt user for tty name if they
2304 don't specify it before getting to the interactive command loop.
2306 * tm-i960.c: Add ADDITIONAL_OPTIONS, etc, to handle -O, -brk,
2307 and -r command line options. Also add hook before main loop
2308 to make it easy to specify a tty.
2310 * TODO: More things to do, one done.
2312 Mon Feb 4 23:57:39 1991 John Gilmore and Mike Tiemann (at cygint.cygnus.com)
2314 * dbxread.c: Make complaint() calls pass pointer, not struct.
2315 Add complaints about badly formatted C++ type information
2316 (const/volatile indicator, and parse errors resulting in
2317 error_type). Fix C++ virtual member fn comment.
2318 (read_struct_type): Avoid bumping pointer if we got a parse
2319 error; this prevents our walking beyond the end of a string.
2320 Terminate loop on null char as well as semicolon.
2321 (process_one_symbol): Fix the LBRAC fix so that it uses the
2322 last previous SLINE, FUN, or SO record's PC address. C++ debug
2323 symbols did not have SLINE records in a useful order compared
2324 to the LBRAC records.
2325 (define_symbol): Handle "catch" records.
2327 * symtab.c (check_stub_type): Added new complain
2328 `stub_noname_complain' and added a consistency check to
2329 keep the debugger from crashing when finishing from an
2330 exception frame. A real fix will be needed later.
2332 Sat Feb 2 10:43:05 1991 John Gilmore (gnu at cygint.cygnus.com)
2334 * infcmd.c (attach_command): Make global.
2336 * Makefile.dist (REMOTE_OBS): Make these compile by default,
2337 but make them easy to comment out. Perhaps later they should
2338 be enabled by what CPU you configure for? FIXME.
2339 (VERSION): Roll to 3.93.
2340 (pinsn.o): Remove rule for obsolete file.
2341 (dbxread.o,coffread.o,mipsread.o): Use ${srcdir} explicitly.
2343 Run down a problem that manifested by printing the wrong function
2344 name in stack traces of read_ofile_symtab. Turned out that the
2345 problem was the SunOS 4.1.1 (and previous) C compiler outputs
2346 the LBRAC symbol with an address in the *data* segment, which
2347 blew our binary search through the blocks.
2349 * dbxread.c: Use the complain() facility consistently to bitch
2350 about problems in the symbol file we are reading.
2351 (finish_block): Add code to check the nesting of the blocks;
2352 complain and Procrust them to fit if wrong.
2353 (make_blockvector): Check the order of the blocks, complain
2354 [but don't cope] if wrong.
2355 (process_one_symbol): ifndef SUN_FIXED_LBRAC_BUG, check LBRAC
2356 symbols to be sure their PC value is greater than the last SLINE
2357 (line number) symbol we've seen, complaining and adopting the
2358 SLINE PC value if wrong.
2360 * symfile.h (struct complaint, complaint_root, complain,
2361 clear_complaints): Add.
2362 * symfile.c (complain, complaint_root, clear_complaints): Add
2363 facility to deal with non-fatal complaints and to regularize their
2365 (symbol_file_add): Clear complaint counters to allow new complaints.
2366 (initialize_symfile): Add 'set complaints' and 'show complaints'.
2368 * dbxread.c (dbx_symfile_read): Remember the address and size
2369 of the string table for the main symbol file, so we won't read it
2371 (dbx_psymtab_to_symtab): Fix the check for main symbol file,
2372 to avoid reading the string table yet again. Lint.
2373 (throughout): Improve filtered output, including word wrap.
2374 (read_range_type): Improve Bothner's fix to handle other types too.
2376 * utils.c: Improve line wrap implementation. Handle unlimited
2377 width by making chars_per_line unsigned.
2378 (puts_filtered): New, easy, function.
2380 * defs.h (puts_filtered): add.
2382 * mipsread.c (compare_symbols, sort_symtab): Remove these fns,
2383 call the identical sort_symtab_syms() in symfile.c instead.
2385 * expread.y: Suggest the `file' command rather than `symbol-file'.
2387 * command.h (enum var_types): Add zinteger for seroable
2389 * command.c (do_setshow_command): Handle var_zinteger. Restructure
2390 nested if's into a switch.
2392 * breakpoint.c (bpstat_print): If bpstat "print" flag is not set,
2393 we did not stop because of a breakpoint (it must have been for
2394 some other reason, like a "stepi"), so don't print anything.
2396 * symtab.c: Include <sys/types.h> all the time. Now that BFD
2397 doesn't include <sys/types.h>, old SunOS's require it for
2400 Sat Feb 2 10:39:15 1991 Per Bothner (bothner@cs.wisc.edu)
2402 A test port of gdb-3.92.6 to the Sony NEWS.
2405 Don't normally link in remote- or vx stuff.
2406 Some of it doesn't compile, and it wastes space for 99% of the users.
2407 Remove reference to no-longer-used HAVE_VPRINTF.
2408 Fixed BFD_DEP typo to BFD_DIR.
2410 Fix cast in arg to bfd_h_getlong.
2411 Make char *prefix be const.
2412 Fix how certain range types are mapped into builtin unsigned int types.
2414 Remove 2 #includes. They cause errors (on Sony, at least),
2415 and aren't needed (they wern't in earlier versions).
2417 print_address_symbolic should never demangle labels
2418 (since it prints *assembler-level* labels).
2420 [This was superseded by the change to printcmd below.]
2423 Add some "volatile" return types to avoid warnings.
2424 If MISSING_VPRINTF add vprintf function and not just macro
2425 (since vprintf is used in printcmd.c).
2427 Unless __GNUC__, use obstack_grow instead of obstack_ptr_grow.
2428 (The latter isn't grokked by some PCC-based compilers.)
2430 [This change is in abeyance, we prefer to fix obstack_ptr_grow.]
2432 Make chunk size of dont_print_obstack 32*4 instead of default 4096.
2433 * nindy-share/coffstrip.c
2434 Added some forward declarations (otherwise, gcc complains
2435 about implicit extern redefined as static).
2437 Sun Jan 20 02:38:19 1991 John Gilmore (gnu at cygint.cygnus.com)
2439 Changes inspired by Per Bothner:
2440 * printcmd.c (print_address_symbolic): Take additional parameter
2441 specifying whether to demangle.
2442 (print_address): Pass in asm_demangle to control demangling.
2443 (print_address_demangle): New fn, takes explicit arg to control
2445 * utils.c: Add new vars demangle and asm_demangle, and let them
2447 (fputs_demangled): If !demangle, just print the argument.
2448 (fprint_symbol): If !demangle, just print raw symbol.
2449 * valprint.c (val_print): Call print_address_demangle rather than
2450 print_address, to cause demangling to depend on the global
2451 rather than assembler-level demangling setting.
2452 * WHATS.NEW, gdb.texinfo: Document.
2454 * main.c (show_command): Show all settings if no arg.
2455 (initialize_main): Make "info set" the same as naked "show".
2456 * command.c (cmd_show_list): Handle prefix commands in the
2457 list, and print the name of the setting as well as its English
2458 description and value.
2460 Allow gdb functions to specify where a line should wrap if it
2461 exceeds the size of a terminal line. Use it to make the output
2463 * utils.c (set_screen_width_command): New fn, mallocs a buffer
2464 of the right size when screen width changes.
2465 (set_screensize_command, screensize_info): Remove #if 0'd fns.
2466 (wrap_here): New fn, indicates a point in the output where we
2467 should wrap the line rather than just letting it overflow at a
2469 (fputs_filtered): Implement wrapping.
2470 (n_spaces): New fn, returns a pointer to N spaces.
2471 (print_spaces_filtered): Use n_spaces.
2472 * defs.h (n_spaces): Declare.
2473 * stack.c (print_frame_info): Wrap with 4-space indent after
2474 fn name and before filename and line number.
2475 * printcmd.c (print_frame_args): Wrap with 4-space indent
2476 before each argument name is printed.
2477 * valprint.c (value_print): Wrap with no indentation before
2479 (val_print_fields): Wrap with indentation relative to nesting
2480 level before each field name.
2481 (val_print): Wrap with nesting indentation before array elements.
2482 * command.c (do_setshow_command): Avoid extra newlines,
2483 wrap with 4-space indent around values printed, end with period.
2484 * WHATS.NEW, gdb.texinfo, gdb-int.texinfo: Document.
2486 * breakpoint.c (breakpoint_1): Implement addressprint for
2487 "info breakpoints" display. Change file name and line number
2488 format to " at file:nnn" rather than " (file line nnn)".
2489 * gdb.texinfo: Document.
2492 Fri Jan 18 07:21:25 1991 John Gilmore (gnu at cygint.cygnus.com)
2494 Frozen for gdb-3.92.6 release.
2496 README, WHATS.NEW: Update for 3.92.6 release.
2498 tconfig/{altos, i386v, i386v32, m88k, umax}: Eliminate
2499 coffread.o from configs since it is now built by default.
2500 tconfig/{3b1, altosgas, arm, convex, hp300bsd, hp300hpux,
2501 i386v-g, i386v32-g, isi, merlin, news, news1000, np1, pn,
2502 pyramid, symmetry, vax, vxworks68}: Eliminate dbxread.o
2503 from configs since it is now built by default.
2505 Makefile.dist: Update for release 3.92.6. Handle files that
2506 have been moved to ../include, ../getopt, or ../bfd. Add
2507 saber.suppress and tests directory. Add config.status to
2508 the release (it will say "none").
2510 coredep.c: Minor formatting fixes.
2512 These changes were made in early December but only checked in now:
2513 * nindy-share/Onindy.c, nindy-share/coffstrip.c,
2514 nindy-share/nindy.c: lint
2515 * nindy-share/nindy.c (ninStopWhy): Don't byteswap the
2516 register values coming back from the target; we store values
2517 in target byte order everywhere.
2519 Wed Jan 16 19:01:37 1991 John Gilmore (gnu at cygint.cygnus.com)
2521 * am29k-opcode.h, am29k-pinsn.c: Add 29050 opcodes.
2523 * valprint.c (cplus_val_print, val_print_fields): New functions,
2524 which print C++ objects. They conspire to avoid printing a
2525 virtual base class more than once, following all the twists and
2526 turns of C++ virtual base rules.
2527 (val_print): Call the above rather than do it by hand.
2529 * symfile.c (symbol_file_add): Only reset symfile_mtime for main
2530 symbol file, not for added files like shared libs. This really
2531 needs to be generalized to a timestamp per file.
2533 * core.c (cleanup_core): Avoid coredump if no core file.
2535 * config.gdb: Accept -host or -target in place of +host or
2538 * coffread.c (find_linenos): Avoid desupported BFD interface
2539 to line numbers. We still read them manually rather than using
2540 BFD's "generic" features.
2542 * gdbrc.tex, threecol.tex: Add GDB reference card and its
2544 Makefile.dist: Add refcard to OTHERS list for creating tar files.
2546 * Makefile.dist: Eliminate use of $< in explicit targets.
2548 * readline/Makefile: Use $< rather than $*.c, which does not
2549 include the VPATH in GNU Make.
2551 * tconfig/i960-bout, tconfig/i960-coff: These are identical
2552 copies of tconfig/i960, added for global configuration
2553 compatability. All i960 versions can read both coff and b.out.
2555 * tm-88k.h: Fix multiline macro that lacked \'s. Remove
2556 COFF_FORMAT and COFF_CHECK_X_ZEROES since these are now handled
2559 * TODO: Think of more things to do.
2561 Wed Jan 2 19:09:29 1991 John Gilmore (gnu at spiff.cygnus.com)
2563 tconfig/{am29k,i960,sun2*,sun3*,sun4*}: Eliminate config
2564 of sdb versus dbx debug symbols. Add kludge for 68881 80-bit to
2565 64-bit float conversion.
2567 tconfig/sun4, tconfig/sun3, xconfig/sun4, xconfig/sun3: Make
2568 equivalent to sun?os4 so global config works.
2570 Wed Jan 2 18:20:51 1991 John Gilmore (gnu at spiff.cygnus.com)
2572 Fix from Eberhard Mattes <mattes@azu.informatik.uni-stuttgart.de>
2574 * main.c: Only declare linesize once; declare pagesize not at
2575 all, since it is never used.
2576 (main): Clear newly allocated line before it is used.
2578 Fri Dec 28 00:13:42 1990 John Gilmore (gnu at cygint)
2580 Further stabilization for the Intel 960.
2582 * Makefile.dist: Parameterize the location of the "include"
2583 and "bfd" directories, as well as "getopt". Add symfile.c.
2584 Link in both dbxread and coffread. Fix up "make depend" to
2585 rewack the locations of include, bfd, and getopt in its output.
2587 * README: Document moving include files, improve some of
2590 * coffread.c: Move common code out to symfile.c. Change
2591 symbol_file_command style interface to use new *_symfile_init
2592 and *_symfile_read interface under BFD. Use BFD internal
2593 info to locate line table, symbols, etc.
2595 * core.c (core_fetch_registers): Rename to get_core_registers
2596 to avoid confusion with fetch_core_registers.
2597 (register_addr): Move to coredep.c, which is already machine
2598 dependent. This leaves core.c pretty clean of dependencies.
2600 * coredep.c (register_addr): Accept this routine from core.c.
2602 * dbxread.c: Move common code (with coffread.c, etc) into new
2603 symfile.c. Each psymtab now contains a pointer to the
2604 format-dependent function that knows how to read it in. Make
2606 (dbx_psymtab_to_symtab): Renamed from psymtab_to_symtab_2.
2607 (process_one_symbol): Add code to complain about a "compiler bug
2608 we muzzle here", if we actually see it.
2610 * eval.c (evaluate_subexp): Insert missing "break" statements
2611 in code that determines whether a variable is an lvalue in
2612 memory, register, or whatever. I detected this via a compiler
2613 bug in which it *almost* mashed out the whole switch statement.
2615 * gdb-int.texinfo: Add minor sections on configuring gdb for
2616 release, and about the README file.
2618 * infcmd.c (registers_info): Fix formatting somewhat. Still
2619 not as pretty as before, but it handles byte swapping.
2621 * remote-nindy.c: If data cache routines are interrupted while
2622 waiting for the remote end, be sure that any uninitialized cache
2623 blocks are on the free list, not on the valid list!
2625 * symfile.h: Flesh out this header file with all the various
2626 routines and variables that have been merged in from dbxread.c
2627 coffread.c, and symtab.c to symfile.c.
2629 * symfile.c: New file, containing code common to dbxread.c,
2630 coffread.c, and some code from symtab.c. All generic code for
2631 reading symbol files should be in here now.
2632 (unrecord_misc_function): Remove unused function.
2634 * symtab.h: Remove file-reading things to symfile.h.
2636 * symtab.c: Remove file-reading things to symfile.c.
2638 * tm-i960.h: Fix FRAME_CHAIN types; define PRINT_RANDOM_SIGNAL
2639 to decode i960 fault types.
2641 * target.h, remote.c, remote-eb.c, remote-vx.c, remote-nindy.c,
2642 target.c: Change type of the "resume" function from int to void,
2643 since its result was never used.
2645 Sat Dec 22 02:51:40 1990 John Gilmore (gnu at cygint)
2647 * main.c: Replace "stupid" with "caution"; you now "set caution
2650 * printcmd.c (print_scalar_formatted): Fix typo in 'g' format
2652 * infcmd.c (do_registers_info): Call val_print to deal with the
2653 byte order of the registers being printed. FIXME, this makes
2654 the formatting of the output uglier.
2656 * infcmd.c (wait_for_inferior): If PRINT_RANDOM_SIGNAL is
2657 defined, call it for signals the debugger doesn't itself use.
2658 The i960 uses this for more detailed fault information.
2660 * remote.c (remote_open): If arg is null, print help rather than
2663 * sparc-xdep.c (register_valid): Avoid declaring size, since
2664 various modules will think of various sizes depending on the
2665 architecture of their tm-file. FIXME, we need protection against
2666 actually entering one of those modules, which would clobber
2667 storage if not for the target architecture compiled into gdb.
2669 * stack.c (up_command, down_command): Always print the frame
2671 (up_silently_command, down_silently_command): New commands
2674 * i960-pinsn.c (reg), i960-tdep.c: Lint.
2676 * i960-tdep.c (i960_frame_chain_valid): Lookup_symbol now takes
2677 more parameters than it used to.
2679 * findvar.c (registers): Increase slop to 256 bytes, which should
2680 protect us against even most RISC machines with large register
2682 (locate_var_value): Move declaration inside related ifdef.
2684 * remote-nindy.c (): Use TIOCSETN rather than TIOCSETP
2685 throughout, to avoid throwing away buffered input from the board.
2686 (nindy_wait): Supply_register takes addr_of_value, not value.
2687 (i960_print_fault): Renamed from i80960_fault.
2688 (nindy_fetch_registers): Avoid have_regs stuff, just get them.
2689 (nindy_store_registers): Avoid regs_changed stuff, just stuff
2691 (nindy_create_inferior): Don't bother to write PC_REGNUM since
2692 we can set the PC in the call to proceed(). Unpush nindy_ops
2693 before pushing it on top, to avoid message to user. Eliminate
2694 commentary from Unix machines that just misleads here.
2695 (reset_command): Fix error message to suggest target command.
2697 Wed Dec 19 11:03:56 1990 John Gilmore (gnu at cygint)
2699 Release 3.92.5 as frozen.
2701 Stabilize the merged release...with help from lint, Saber C,
2704 Everywhere: Add include files needed to declare return types
2705 of functions called.
2707 * gdb.texinfo: Roland Pesch is documenting gdb, glory be!
2709 * breakpoint.h: Add undeclared breakpoint functions, and some
2710 functions for display handling since I couldn't think of a better
2713 * breakpoint.c (insert_breakpoints): Make code for disabling
2714 shared library bkpts more likely to work. It's used when we
2715 rerun a program and stop before the shared library has been
2717 (breakpoint_cond_eval, bpstat_stop_status): Pass arg as int,
2718 cast from pointer, so it squeezes through catch_errors.
2719 (bpstat_stop_status): Fix logic broken some time ago. We now
2720 always create a bpstat if the stop address matches a breakpoint,
2721 even if we don't stop there -- just like the old code used to do
2722 before I got my fingers into it (sigh).
2723 (breakpoint_1): Print "ignore count" after "stop only if"
2724 condition, since that's how it actually works.
2725 (mention): Handle watchpoints as well as breakpoints.
2726 (watch_command): use set_raw_breakpoint and mention to do most
2727 of the work (and initialize all the fields!). Only pass one
2728 arg to parse_c_expression, since that's all it takes.
2730 * command.c (not_just_help_class_command): Rename arg to args
2731 since we ignore "unused argument" warnings on vars named "args".
2732 inflow.c (child_terminal_info): ditto.
2733 infptrace.c (kill_inferior): ditto
2734 main.c (catch_errors, version_info, quit_command, pwd_command,
2735 source_command, dump_me_command, editing_info,
2736 set_history_size_command, set_history, show_history,
2738 stack.c (locals_info): ditto
2739 target.c (target_files_info): ditto
2740 valprint.c (set_input_radix, set_output_radix): ditto
2742 * core.c: Remove old variables for handling core and exec file
2743 sections (data_start, data_end, stack_start, stack_end,
2744 reg_stack_start, reg_stack_end, reg_stack_offset, text_start,
2745 text_end, exec_data_start, exec_data_end, text_offset,
2746 exec_data_offset, data_offset, stack_offset). They're
2747 superseded the more general build_section_table and
2749 (get_exec_file): Mention the `file' command.
2750 (read_memory_check): Rename to memory_error, and only call it
2751 in the case of an actual error.
2752 (read_memory, write_memory): call memory_error.
2753 (core_fetch_registers): Register section name is ".reg".
2755 coredep.c: Remove a bunch of crud now that all this file does
2756 is pull the registers out of a core file.
2757 (fetch_core_registers): Rewrite to actually work, I hope.
2759 dbxread.c: Use a.out.gnu.h, not system a.out, now.
2760 Replace index() with strchr(). Remove all the pre-BFD macro
2761 definitions for accessing the symbol file.
2762 (struct dbx_symfile_info): Encapsulate the information that
2763 dbx_symfile_init needs to pass to dbx_symfile_read in this
2766 (dbx_new_init, dbx_symfile_init, dbx_symfile_read,
2767 dbx_symfile_discard): Rearrange symbol file reading to divide
2768 the format-specific part from the format-independent part,
2769 leaving the format-independent part such as file name expansion
2770 and opening in symtab.c. This replaces
2771 partial_symbol_file_open and partial_symbol_file_read.
2772 Symbol_file_read, add_file, add_file_target_command,
2773 add_file_addr_command move to symtab.c. Pass an explicit
2774 "mainline" flag for when reading the main symbol table, rather
2775 than relying on the offset address to be zero or nonzero.
2777 (dbx_symfile_read): Don't allow void *'s to be printed as
2779 (SWAP_SYMBOL): Use bfd routines to byte-swap the symbols.
2780 (ADD_PSYMBOL_TO_LIST): Make the "function call rather than
2781 macro" debug version really work.
2782 (read_dbx_symtab): Remove unref'd parameter inclink.
2783 Avoid swapping N_SLINE symbols, for speed.
2784 Merge N_TEXT!N_EXT case with the other external symbol
2785 definitions' case. Add comments.
2786 (start_psymtab): Allocate the symfile name in the psymtab on
2787 the psymbol_obstack, rather than using the caller's storage.
2788 (end_psymtab): Only allocate a dependencies list if there are
2790 (psymtab_to_symtab_2): Use BFD when reopening file to read
2791 its symbols for real.
2792 (read_struct_type): Add FIXME comments where it needs work
2794 (read_huge_number): Add FIXME about overflows.
2795 (read_range_type): Add FIXME about comparing a long to 1<<32.
2797 * coffread.c: Minor changes to move things closer to the new
2798 regime with symtab.c and dbxread.c Major work is still needed
2801 * exec.c (exec_file_command): Remove old variables (see core.c
2803 (xfer_memory): If memory transfer is right at the end of a
2804 section, don't lose.
2806 * findvar.c (get_saved_register): If value is in a real
2807 register, LVAL is lval_register, not lval_memory.
2809 frame.h: Declare print_sel_frame and record_selected_frame.
2811 gdb-int.texinfo: New file, for GDB internals documentation.
2812 Very simple, unformatted doc of cleanups is there for now.
2814 gdbcore.h: Remove obsolete variables that described a.out
2815 section addresses and offsets. (See core.c above.)
2816 Declare fetch_core_registers and registers_fetched.
2818 getopt.c: Declare char *alloca(); even on SPARC.
2820 infcmd.c (run_command): Call target_kill rather than
2822 (step_command, next_command, stepi_command, nexti_command):
2823 Declare from_tty parameter even though we don't use it.
2824 (run_stack_dummy): argument BUFFER is a char array, not
2825 a pointer to REGISTER_TYPE.
2826 (finish_command): using_struct_return needed a value *,
2827 not a struct symbol *.
2829 * infptrace.c (child_xfer_memory): To avoid dependency on
2830 where sections are in memory, try PT_WRITE_D and if that fails,
2831 try PT_WRITE_I. Most Unixes don't care which you use.
2833 * infrun.c (step_resume_break_shadow): Change to array to
2834 match other breakpoint shadow storage.
2835 (clear_proceed_status): Pass address of bpstat to
2836 bpstat_clear, not the bpstat itself.
2837 (child_create_inferior): FIXME comment about if the child
2839 (start_inferior): Remove old function.
2840 (child_open): Use target_kill rather than kill_inferior.
2841 (wait_for_inferior): Ditto.
2842 (insert_step_breakpoint, remote_step_breakpoint): Use
2843 new step_resume_break_shadow.
2845 * inftarg.c (child_wait): If all child processes die,
2846 pretend that the one being waited for exited with signal 42.
2848 * main.c (command_line_input): When scanning for comments,
2849 don't coredump on unclosed quotes.
2850 (quit_command): Use target_kill rther than kill_inferior.
2851 (_initialize_main): Rename class_user from "user" to
2854 * printcmd.c (print_command_1): Initialize "fmt" if no format
2855 is specified by the user.
2856 (print_frame_args): Only add to args_printed if we are
2857 actually fetching args from the stack (avoiding undefined
2859 (_initialize_printcmd): Remove bogus \{ from string.
2861 * remote-eb.c (eb_open): Avoid coredump on no argument.
2863 * remote-nindy.c: Bring out of Intel environment into new
2864 target environment. Remove all conditional compilation on
2865 I80960. Massive hacking throughout.
2866 (nindy_xfer_inferior_memory): New routine stolen from
2868 (nindy_create_inferior): New routine pieced together, probably
2869 not quite working yet.
2870 (nindy_ops): New target_ops struct for nindy.
2872 * remote-vx.c: Use write_memory rather than target_write_memory
2873 to get error checking.
2874 (vx_add_file_command, vx_open): Use symbol_file_add rather than
2876 (vx_create_inferior): Use target_terminal_ours...
2878 * signame.c (_initialize_signame): Always initialize, since
2879 we need the table for things other than psignal.
2881 * solib.c (solib_add): Use symbol_file_add, not add_file.
2882 (solib_address): Return boolean result rather than struct
2883 pointer which nobody else knows the type of.
2885 * sparc-tdep.c, valops.c: Use write_memory rather than
2886 target_write_memory, to get error checking.
2888 * stack.c (locals_info, catch_info, args_info,
2889 get_selected_block, frame_command, up_command): Use
2890 target_has_stack, rather than have_inferior_p or
2893 * sun3-xdep.c (fetch_core_registers): Rewrite for new BFD regime.
2895 * symfile.h: New file, defining the interface between the
2896 generic and object-file-specific symbol reading code.
2898 * symtab.c: Move generic symbol-reading interface to symtab.c,
2899 from dbxread.c, coffread.c, mipsread.c, etc. Add symtab_fns
2900 table to map BFD targets to symbol-reading modules in GDB.
2901 Change index to strchr.
2902 (lookup_struct_elt_type): Use error() rather than hand-made
2903 simulations thereof.
2904 (lookup_partial_symbol): Speedup slightly when length == 0.
2905 (symbol_file_add): New function.
2906 (symbol_file_command): Call it.
2907 (symfile_open, symfile_init): New function.
2908 (add_file_target_command, add_file_addr_command): moved from
2911 * target.c (target_command): use target_kill.
2913 * target.h (target_files_info): Don't declare, never called
2916 * tm-sun2.h, tm-sun3.h (STACK_END_ADDR): Use system include
2917 files to determine stack end address.
2919 * valarith.c (value_x_binop, value_x_unop): Change error message
2920 to be more useful. Pass proper argument to value_struct_elt.
2922 * valops.c (value_assign): FIXME comment that long long
2923 bitfields will break here.
2925 * Makefile.dist: Add symfile.h, remote-nindy.c, remote-eb.c.
2926 Update `make saber_gdb' to work better.
2928 * TODO: A woman's work is never done.
2930 * cplus-dem.c, environ.c, inferior.h, infrun.c, inftarg.c,
2931 main.c, obstack.c, printcmd.c, remote-eb.c, remote-nindy.c,
2932 remote-vx.c, remote.c, solib.c, source.c, sparc-pinsn.c,
2933 sparc-tdep.c, sparc-xdep.c, symmisc.c, symtab.c, symtab.h
2934 target.c, terminal.h, tm-sparc.h, tm-sunos.h, utils.c,
2935 valops.c, valprint.c, exec.c: Lint.
2938 Wed Dec 12 23:44:15 1990 John Gilmore (gnu at cygnus.com)
2940 Continuing Intel 960 port merge of GDB.
2942 * Makefile.dist: Merge i960 "nindy-share" files. Rename
2943 malloc.h to gmalloc.h to avoid name conflicts in /usr/include.
2944 Don't ship gdb.dvi in tar file. Link gdb with init.o, not init.c.
2945 Wack over "make depend" so it handles files in subdirectories
2946 vx-share, nindy-share, bfd, and in the current directory.
2948 * blockframe.c (get_prev_frame_info): Remove fatal error
2949 if stack not defined.
2951 * core.c (core_open, core_detach): New functions that handle
2952 the old "core-file" command as "target core" and "detach" instead.
2953 (core_file_command): Call them.
2954 (core_xfer_memory): Use common routine xfer_memory.
2956 * dbxread.c: Include a.out.gnu.h, not system a.out.h.
2957 dbxread now uses bfd for everything but symbol reading itself.
2958 BFD internals are used to drag out the relevant file offsets.
2959 (partial_symbol_file_open): Change args all around for BFD.
2961 * symtab.c: Rename "value" to "val" everywhere, so we can
2963 (symbol_file_command): New command, moved from dbxread.c
2964 and coffread.c. It uses BFD to read the file, then vectors
2965 based on its type, to dbx or coff symbol readers.
2966 * symtab.h: Extern a few vars for symbol_file_command.
2968 * target.h: Breakpoint takes a char * save area, not a char **.
2970 * valprint.c (val_print): When unpacking bitfields, offset
2971 the address in gdb of the value, if it is declared with a shorter
2972 type. Remove the last "runtime kludge test" of host byte order.
2974 * utils.c: Remove old my_bfd_read routine.
2976 * stack.c (frame_info): Use target_has_stack. Print program counter
2977 register's actual name rather than "pc", since it's called the
2978 "ip" (instruction pointer) on the i960 (sigh).
2980 * target.c (target_command): Add command for selecting a target
2981 type and calling its open routine. This is used for initiating
2982 communication with a particular target, in a generic way.
2984 * tm-i960.h: Update for modern gdb. Remove semicolons from
2985 various macros. Handle reading struct return convention, and
2986 error-out attempts to return structs with the "return" command.
2987 Be sure gdb doesn't think we know how to call functions in the
2990 * i960-tdep.c: Rename FRAME_CHAIN_VALID and FRAME_FIND_SAVED_REGS
2991 to i960_xxx in lower case.
2992 (arg_address): Circumvent errors due to LOC_ARG_BLOCK
2993 not being defined yet.
2995 * remote.c (remote_open): Call start_remote to initialize
2996 wait_for_inferior during open.
2997 (remote_xfer_inferior_memory): Return length written rather
3000 * remote-vx.c (target_command -> vx_open): Use new generic
3002 * remote-eb.c, inftarg.c, exec.c: ditto.
3004 * infrun.c: Fix comments.
3005 (attach_program -> child_open): Use new generic target command.
3006 (wait_for_inferior): Clear saved register values before target_wait,
3007 so target_wait can set some of them if convenient.
3009 * infptrace.c (fetch_inferior_registers, store_inferior_registers):
3010 Return success indicator, not void.
3011 (child_xfer_memory): Avoid fetching initial word if we'll
3012 overwrite it anyway.
3014 * infcmd.c (attach_command): Use new generic target open routine.
3015 (_initialize_infcmd): Update doc on attach and detach commands.
3016 (do_registers_info): Merge in a byte-order problem as a FIXME
3019 * findvar.c (find_saved_register): Avoid problem in current frame.
3020 (read_relative_register): Ditto.
3021 (write_register): Convert byte order on the way out.
3023 * exec.c (file_command): Add.
3024 (add_to_section_table, exec_command): Use new bfd_map_over_sections.
3025 (xfer_memory): Common function between core_xfer_memory and
3027 (exec_xfer_memory): Use it.
3029 * pn-opcode.h: Document that a "PN" is a Gould PowerNode.
3031 * breakpoint.c, breakpoint.h, symtab.h, value.h, frame.h, utils.c,
3032 valops.c, stack.c, target.c, sparc-xdep.c, source.c, printcmd.c,
3033 infcmd.c, i960-pinsn.c, eval.c, defs.h: lint and gcc -Wall.
3035 Sun Dec 2 16:45:06 1990 John Gilmore (gnu at cygnus.com)
3037 Merge Intel 960 port of gdb, continuing...
3039 * dbxread.c (partial_symbol_file_open, partial_symbol_file_read,
3040 symbol_file_command): Pass from_tty arg to hush 'em up.
3042 * coffread.c (symbol_file_command): Avoid output if from_tty != 1.
3043 Add magic numbers for 960 COFF format.
3045 Fri Nov 30 09:18:20 1990 John Gilmore (gnu at cygnus.com)
3047 Merge Intel 960 port of gdb, from Intel "1.2" release.
3049 CHANGE_LOG entries from their port, which was based on
3052 Thu Sep 6 11:02:22 PDT 1990
3053 Remove temp file if download is interrupted.
3055 Wed Aug 1 09:08:33 PDT 1990
3056 Now uses binary protocol to talk to NINDY.
3057 Old hex protocol (NINDY 2.13 and older) supported with -O switch.
3058 Times out after 5 seconds when trying to talk to NINDY.
3060 Tue May 29 12:54:49 PDT 1990
3061 Added variable baud rate (-b switch).
3062 Source code reorganization.
3064 Thu Apr 26 11:09:55 PDT 1990
3065 More cleanup of batch mode; specifically, execute "-s", "-e", and
3066 "-se" switches as soon as they are encountered on the invocation line.
3068 Fri Apr 20 13:47:15 PDT 1990
3071 Thu Apr 19 09:54:28 PDT 1990
3072 Add 'reset' command.
3074 Wed Apr 18 09:48:07 PDT 1990
3075 After opening remote tty, wait for 1 second to go by without input
3076 from it before trying to talk to NINDY (fixes problems with the
3077 Heurikon HK80/V960E).
3079 Mon Apr 4 16:33:05 PDT 1990
3080 Some output was not being suppressed in 'batch' mode.
3082 Thu Mar 22 15:31:11 PST 1990
3083 Ask user if old symbol table should be deleted when new file is
3086 Allow user to run a program downloaded before gdb960 was brought up.
3088 Correct "exec-file" help message for i80960 context.
3090 Correct bug in calculating user space address: could occasionally
3091 corrupt user program.
3093 Make sure to zero low-order bits in rip's because of bug in 960CA
3094 A-step part: could cause operation faults when "next"ing across
3097 Correct bug that made it impossible to get source line numbers for
3098 code loaded at addresses higher than 0x7fffffff.
3100 Wed Jan 10 12:43:22 PST 1990
3101 Open remote tty for exclusive use.
3103 Fri Jan 5 12:14:42 PST 1990
3104 Correct disassembly (CA manual was right after all):
3105 opcode for sysctl is 0x659
3107 Mon Oct 23 12:03:04 PDT 1989
3108 Use G960BASE and G960BIN environment variables to find 'sx' utility.
3110 Mon Oct 16 14:15:09 PDT 1989
3111 "sfr0"-"sfr31" should have been named "sf0"-"sf31"
3113 Mon Oct 2 15:56:31 PDT 1989
3115 Added 960CA disassembly support.
3117 To simplify maintenance:
3118 - eliminated use of symblic links on pinsn.c: use i960-pinsn.c
3120 - eliminated opcode.h: incorporates tables into i960-pinsn.c
3121 - moved 960-specific routines from i960-pinsn.c to i960-md.c
3122 - made disassembly interface identical to that in gdmp960.
3126 Wed Nov 28 21:32:48 1990 John Gilmore (gnu at cygint)
3128 * target.h: Allow targets to stack. Add target_has_memory,
3129 _registers, etc. Restructure memory access and "info files"
3130 to walk the target stack.
3131 * exec.c, core.c, inftarg.c, remote.c, remote-vx.c, remote-eb.c,
3132 target.c: Change tables to match target.h.
3133 * inflow.c (child_mourn_inferior): pop child_ops.
3134 (generic_mourn_inferior): Use new has_stack flag.
3135 * infptrace.c (child_xfer_memory): New memory regime.
3136 * inftarg.c (child_files_info): New "info files" regime.
3137 * remote-eb.c: New memory regime, new info files.
3138 * remote-vx.c: New memory regime, new info files. Now use
3139 separate targets for VxWorks attachment to machine, and
3140 actually running a process under VxWorks, since one has
3141 stack & execution & regs and the other doesn't.
3142 * remote.c: New memory regime, new info files.
3143 * sparc-xdep.c (fetch_core-registers): New memory regime.
3144 * target.c: New routines and support for stacked targets,
3145 new memory regime, new info files regime.
3148 Generalize section handling for an arbitrary number of sections,
3149 including use of the new BFD (binary file) library.
3150 * gdbcore.h: Add struct section_table.
3151 * exec.c (build_section_table): Iterate all sections and
3152 record what gdb needs to know about them.
3153 (exec_command): Use it.
3154 (exec_xfer_memory): Use the table.
3155 (exec_files_info): Print the table.
3156 * core.c (core_file_command, core_xfer_memory, core_files_info):
3158 * source.c (find_source_lines): Use bfd_get_mtime.
3159 * dbxread.c: Quick changes to make it compile with new BFD.
3160 * utils.c (error): Avoid using bfd_error in generic routines.
3162 * core.c (core_fetch_registers): Get from the ".regs" section of
3164 * sparc-xdep.c (fetch_core_registers): Use the .regs info.
3166 * inferior.h (attach_flag): Export.
3167 * infcmd.c (run_command): use new target_create_inferior.
3168 * infrun.c (child_create_inferior): Don't return result.
3169 * Makefile.dist (VERSION): 3.91.4.
3171 Fri Nov 23 28:15:38 1990 John Gilmore (gnu at cygint)
3173 * breakpoint.c (bpstat_num): Handle breakpoints which have
3174 since been deleted, such as temporary breakpoints.
3175 infcmd.c (program_info): ditto.
3177 * core.c (core_file_command): Display the frame where the core
3182 * remote-vx.c (target_command): Merge in target command from
3183 targ-vx.c. A few other cleanups.
3185 * TODO, Projects: Lots more stuff to do...
3187 Fri Nov 23 18:15:38 1990 John Gilmore (gnu at cygint)
3189 Massive changes to wall off the remote-debugging interface
3190 behind a function vector. The port to handle VxWorks targets
3191 is also part of this.
3193 All files: Replace references to renamed functions,
3194 remove references to remote_debugging, remove references to
3195 have_include_file, have_core_file in favor of target_has_stack,
3196 target_has_memory, etc.
3198 * Modularize the breakpoint interface.
3199 breakpoint.h (BREAKPOINT_MAX): New define sets max length of
3200 a breakpoint instruction.
3201 breakpoint.c: struct breakpoint's shadow_contents now sized as
3203 (insert_breakpoints): Vector to target to install breakpoints.
3204 (remove_breakpoints): Vector to target here too.
3205 Remove REMOTE_SA_SPARC kludges and other remote_debugging.
3206 sparc-tdep.c (single_step): Use new breakpoint interface for
3207 the single-step breakpoints.
3208 mem-break.c (memory_insert_breakpoint, memory_remove_breakpoint):
3209 New file, contains routines to insert and remove breakpoints by
3210 reading out the old contents and later replacing them. This is
3211 how ptrace breakpoints work, and many remote systems as well.
3213 * tm-vxworks68.h: New config file, overrides a few things for
3214 Wind River's preferences.
3216 * target.h: New file, for transfer vector used to talk to the
3217 inferior (child, attached, core, exec, remote, etc). All accesses
3218 to the thing being debugged should come through these vectors.
3219 target.c: New file, routines to handle transfer vector.
3220 (various files): Add transfer vectors XXX_ops for the various
3221 targets and pseudo-targets (core files, etc) we support.
3223 * breakpoint.c (bpstat_stop_status): Further explorations of
3224 watchpoints and why things don't work all the time.
3225 (bpstat_alloc): New fn to allocate a bpstat and chain it.
3227 * config.gdb: Only add "source ${srcdir}/.gdbinit" to
3228 the local gdbinit if it doesn't already have it.
3230 * core.c (core_ops): add and install.
3231 Allow core debugging without exec file.
3233 * dbxread.c (free_and_init_header_files): Merge two fns.
3234 (end_symtab): Free named symbol table when a new version comes in.
3235 (read_dbx_symtab): Relocate all kinds of symbols with base
3236 address. First step toward handling different text, data, bss
3238 (add_file_addr_command): Renamed add_file_command.
3239 (add_file_command): Vector to remote handler.
3240 Add "load" as an alias for "add-file" command.
3242 * defs.h: Allow "volatile" to be used in non-ANSI; use it for
3243 non-returning functions.
3245 * exec.c: Add exec_ops, and push it as a target when an exec
3248 * infcmd.c (run_command): Pass executable file name and arg list
3249 separately when starting an inferior. Permit "run" when no exec
3250 file is specified, for VxWorks.
3251 (detach_command): Move to child_detach in inftarg.c.
3253 * inftarg.c: New file. Unix-child-specific routines, and the
3254 child_ops structure.
3256 * inferior.h (registers): Export "registers" as the way for
3257 target dependent register handlers to find gdb's local copy of
3258 the registers. Rename "stop_after_attach" to "stop_soon_quietly"
3259 since it is now used by places that want wait_for_inferior to
3260 handle the grunge but want to see every trap from the inferior.
3262 * inflow.c (create_inferior): Pull out, and merge into infrun.c.
3263 Eliminate remote_debugging hooks in terminal handling.
3265 * infrun.c: Replace start_inferior with child_create_inferior.
3266 Move all the hair of Unix shells and ptrace idiosyncracies into
3267 child_create_inferior, so remote handlers don't have to deal.
3268 Remove running_in_shell. Rename stop_after_attach to
3269 stop_soon_quietly, and use it in a few other places where we want
3270 to just call wait_for_inferior and get control back on the first
3271 trap. trap_expected now never takes a value > 1.
3272 (init_wait_for_inferior): Initialize static vars when a new
3275 main.c (gdbinit): Add new hook for .gdbinit file name, let
3276 it be overridden by config files as GDBINIT_FILENAME.
3277 (DEFAULT_PROMPT): Add new hook for overriding (gdb) prompt.
3278 Both of these are used for VxWorks gdb.
3280 mcheck.c: rename include file "gmalloc.c" to avoid problems
3281 with system include file "malloc.c".
3283 param-no-tm.h: New include file, same as param.h but does not
3284 include the default "tm.h" file. This is used in files where
3285 the target is known, e.g. remote-eb.c or sparc-xdep.c.
3287 param.h: Now just a shell that includes tm.h and param-no-tm.h.
3289 remote-vx.c: New file, VxWorks remote debugging support. Uses
3290 RPC routines that are shared with the target system, in directory
3293 remote.c: Vectorize remote interface.
3295 source.c: Globalize source_path, and make an alias "l" for "list"
3296 since we now have the "load" command.
3298 sparc-xdep.c: Use new param-no-tm.h.
3300 symmisc.c (free_named_symtab): Add new function from Wind River.
3301 However, ifdef it out for now while we think about what it should
3304 tm-sun3.h, xm-sparc.h, xm-sun3.h, xm-symmetry.h: Move
3306 the xm- file, and change its name to CHILD_PREPARE_TO_STORE, since
3307 non-Unix-children handle this with their own code in the target
3310 Makefile.dist: Roll version to 3.92.3. Add vx-share stuff to
3311 source and target lists. Add vx-share to default list of include
3312 directories. Add new files to src and target lists: mem-break,
3313 target, inftarg, remote-eb, remote-vx, targ-vx. Be sure the
3314 ${srcdir} versions of munch and createtags are used.
3316 * valops.c (find_function_addr): Split out of call_function.
3317 (call_function_by_hand): Rename call_function; this function
3318 calls functions in the target by laboriously patching the target
3319 word-by-word with the right stack, args, regs, etc.
3322 Mon Nov 5 17:29:10 1990 John Gilmore (gnu at cygint)
3324 Handle AMD 29000 a bit better.
3326 * remote-eb.c (readchar): Mask received char log to make it readable.
3327 (remote_start): Pass arguments down to executing program.
3328 Make startaddr unsigned.
3329 infrun.c (start_inferior): Accept args, pass them to
3331 infcmd.c (run_command): Pass args down to start_inferior.
3333 * tconfig/am29k-aout, tconfig/am29k-coff: New files specifying
3334 the target object file format.
3335 tm-29k.h: Pay heed to COFF_ENCAPSULATE.
3337 * am29k-pinsn.c (print_insn): Print 0x on hex numbers in disassembly.
3338 am29k-tdep.c (examine_prologue): Better checking of function prefixes.
3340 Sun Oct 7 18:20:45 1990 John Gilmore (gnu at cygint)
3342 * Makefile.dist (VERSION): Roll version to 3.91.9 and freeze.
3343 * TODO: We did a few things, we have more to do though.
3345 * xm-sparc.h (CLEAR_DEFERRED_STORES): Define.
3346 * inflow.c (inferior_died): Clear deferred stores.
3348 * Debug problems with dummy frames and calls to the inferior.
3349 * tm-sparc.h (PUSH_DUMMY_FRAME, POP_FRAME): Move to sparc-tdep.c.
3350 * sparc-tdep.c (do_restore_insn): Simplify.
3351 (sparc_frame_find_saved_regs): Simplify and fix what we find.
3352 (sparc_push_dummy_frame): Simplify and fix what we push.
3353 (sparc_pop_frame): Slightly more hair here, deciding whether
3354 we are restoring a saved PC or returning to a return address in %i7.
3355 * sparc-xdep.c (read_inferior_registers): Debug if valid reg is read.
3357 * utils.c (xmalloc, xrealloc): Return type depends on __STDC__.
3358 * symtab.h (xmalloc): ditto, for obstack_chunk_alloc.
3359 * obstack.h (chunkfun): ditto.
3360 * defs.h (xmalloc, xrealloc): ditto
3362 * utils.c (quit): Grab the terminal from the child if necessary.
3364 * inflow.c (term_status_command): Rename to term_info, change
3367 * sparc-pinsn.c (print_insn): Disassembly prefers real instructions.
3368 (is_delayed_branch): Speed up.
3369 * sparc-opcode.h: Add ALIAS bit to aliases. Fix up opcode tables.
3370 Still missing some float ops, and needs testing.
3372 * Support for input and output radixes other than base 10
3373 * defs.h (input_radix, output_radix): Declare.
3374 * expread.y (yyparse, parse_number): Handle changes of input
3375 radix, and ambiguous names-or-numbers in radixes >10.
3376 * printcmd.c (print_scalar_formatted): Print formatted hex
3377 numbers in varying column widths.
3378 * valprint.c (val_print): Use output_format to print scalar ints.
3379 (set_input_radix, set_output_radix, set_radix): Create.
3380 (set_output_radix): Set output_format from output_radix.
3381 (_initialize_valprint): add `set radix' but leave the others off.
3383 * main.c (execute_command): Let stupid questions be turned off.
3384 (_initialize_main): Handle "set stupidity", etc.
3386 * main.c, inflow.c, inferior.h, frame.h, command.c, defs.h,
3387 sparc-pinsn.c, sparc-xdep.c, value.h, valops.c, values.c: Lint.
3389 Tue Oct 2 11:20:02 1990 John Gilmore (gnu at cygint)
3391 * TODO, Makefile.dist, ChangeLog: Freeze for 3.91.8 release.
3392 bfd stuff is still screwed up, but with some manual work, it
3395 * breakpoint.c (bpstat_do_actions): Start over if a command
3396 proceeds the inferior, since the inferior will have stopped and
3397 will need to have its new stop-actions taken care of.
3399 * dbxread.c (read_struct_type): Expression gives Sun3 4.0.3
3400 compiler fits, simplify it.
3402 * gdb.texinfo (directory command): Doc new dir command.
3403 source.c (directory_command): "dir" now puts things on the front
3404 of the path, moves dups up front, and handles multiple names
3405 on the command line, inserting each one in order. It also
3406 blows away cached line and full_filename info.
3408 * stack.c (backtrace_command): Skip "more stack frames follow"
3411 * Change #ifndef HAVE_VPRINTF to #define MISSING_VPRINTF in
3412 xm-convex.h, xm-hp300bsd.h, xm-isi.h, xm-merlin.h, xm-news.h,
3413 xm-np1.h, xm-pn.h, xm-pyr.h, xm-symmetry.h, xm-umax.h, xm-vax.h.
3414 The only odd one was Gould NP1, which had defined vprintf to
3417 * Merge Ted Goldstein <tedg@Eng.sun.com>'s changes for epoch.
3418 printcmd.c (print_command_1): Pass 'inspect' flag down as a global
3419 variable, inspect_it.
3420 valprint.c (print_string, val_print): Use the global inspect_it
3421 to indicate whether to print in Epoch style or normal style.
3423 Mon Oct 1 23:55:26 1990 John Gilmore (gnu at cygint)
3425 * printcmd.c (call_command): add an alias for the "print" command
3426 which runs expressions and doesn't print the result if void.
3427 (print_command_1): implement it.
3429 * command.c: Remove #if 0'd code. Initialize all the fields
3430 in add_cmd (). Rename do_nothing_command to
3431 not_just_help_class_command, and make it externally visible.
3432 command.h: add user_commands to struct.
3433 * main.c (define_command): Don't overload c->function with a char
3434 string as well as a function pointer.
3436 * eval.c (evaluate_subexp): Reinstall tiemann changes to
3437 calling convention of value_struct_elt () that got dropped in
3440 * tm-sparc.h (FRAME_FIND_SAVED_REGS): move to sparc-xdep.c.
3441 sparc-tdep.c (sparc_frame_find_saved_regs): ditto.
3443 * tm-sparc.h (POP_FRAME): replace some constants with defines.
3445 * sparc-xdep.c (store_inferior_registers): defer stores to regs
3446 until a good time (e.g. when we are about to run the child),
3447 saving ptrace calls.
3448 * infrun.c (proceed): handle DO_DEFERRED_STORES.
3449 * tm-sparc.h: define DO_DEFERRED_STORES.
3451 * sparc-xdep.c (store_inferior_registers): when storing float
3452 registers, don't store stack regs too. When storing the SP,
3453 however, DO store the stack regs too. This fixes a bug in which
3454 the dummy frame is not recognized when a call_function finishes,
3455 because its frame pointer (in the stack regs) was never
3457 (read_inferior_registers): Mark WIM and TBR and FPS and CPS valid
3458 even though we don't know how to read them from an inferior.
3459 valops.c (call_function): Comment about storing SP.
3461 * infrun.c (save_inferior_status): Save away the original bpstat
3462 chain so it can be restored later. Install the copied version for
3463 use by whoever saved the status. It will be blow away by
3464 restore_inferior_status, and the original chain restored. This is
3465 important for people who have pointers into the original.
3467 * breakpoint.c, command.h, copying.awk, dbxread.c, defs.h,
3468 findvar.c, frame.h, obstack.h, obstack.c, inflow.c, value.h,
3469 main.c, printcmd.c, sparc-tdep.c, symtab.c, valprint.c: lint
3472 Fri Sep 28 20:32:46 1990 John Gilmore (gnu at cygnus.com)
3474 * Makefile.dist: Roll version to 3.91.8. Add bfd.h and bfdconfig.h
3475 temporarily to the makefile. Add am29k-opcode.h and WHATS.NEW.
3476 Add stuff.c and kdb-start.c to the OTHERS list for tar files.
3478 Fri Sep 28 19:12:12 1990 John Gilmore (gnu at cygint)
3480 * Merge Mike Tiemann's multiple inheritance changes from Sun.
3481 Store the baseclasses in a type struct starting from array element
3482 0 rather than from the unusual array element 1.
3484 dbxread.c: the above.
3485 (virtual_context): Add
3486 Read new debug information about which virtual function table
3487 a virtual function is from, and store it in fn_field.fcontext.
3489 symtab.h: Add fcontextt. Fix baseclass indices. Typo in
3490 TYPE_FN_FIELD_STATIC_P.
3492 symtab.c: the above.
3493 valops.c: the above. Handle pointer casts of object *'s.
3494 (search_struct_method): Add.
3495 (value_struct_elt): First arg is now a pointer to a value, and is
3498 valprint.c: the above.
3499 values.c (value_virtual_fn_field): Add type arg. Handle
3500 offsetting to the proper object when calling virtual fns.
3502 (baseclass_addr): Add valuep arg.
3504 * README: Document the current state of BFD config (missing).
3505 * TODO, ChangeLog, Makefile.dist: Roll version.
3506 * WHATS.NEW: Add summary of changes since 3.5.
3508 Thu Sep 27 16:23:12 1990 John Gilmore (gnu at cygint)
3510 * dbxread.c (read_struct_type): Clear bit vectors whenever
3512 symtab.c (B_CLRALL): define.
3514 * tm-sparc.h (STORE_RETURN_VALUE): Avoid clobbering types by
3515 using == rather than =. Huh... This fixes the dreaded problem
3516 wherein builtin_type_int becomes TYPE_CODE_FLT.
3518 * core.c (info_files): Show the inferior pid.
3520 * config.gdb: Avoid putting "dir" command into .gdbinit. GDB
3521 already knows how to look in the source directory.
3523 * Remove psymtab hair from many places. Remove duplicated code
3524 for searching symbol tables. Hide psymtabs from most places.
3525 Make it fast to get from a psymtab to its symtab.
3527 blockframe.c (blockvector_for_pc): Remove psymtab hair.
3528 coffread.c (psymtab_to_symtab): Rename to psymtab_to_symtab2.
3529 mipsread.c (psymtab_to_symtab): Rename to psymtab_to_symtab2.
3530 dbxread.c: export psymtab_to_symtab, make it work if called N times.
3531 (psymtab_to_symtab): Rename to psymtab_to_symtab2. Initialize
3532 new symtab completely. New psymtabs get symtab pointer
3533 initialized to zero. Remove MI warning printf.
3534 symtab.h: Comments. Add psymtab to symtab pointer.
3535 (PSYMTAB_TO_SYMTAB): New macro.
3536 symtab.c: use PSYMTAB_TO_SYMTAB. Add psymtab_to_symtab and export it.
3537 source.c: use PSYMTAB_TO_SYMTAB. Remove symtab version and
3539 stack.c (backtrace_command): Avoid pre-pass to read symbols, if
3541 (print_frame_info): Avoid special-casing symbols that have not yet
3544 * source.c (open_source_file): Quick path if we have already
3545 located the source file by its full name.
3547 * symtab.c (lookup_symbol): Use find_pc_symtab rather than
3548 find_pc_psymtab. When a name is found in the misc function
3549 vector, search the symbol table for its mangled name, not the
3550 name that the user typed.
3552 * bfd.h: Fix missing comment terminators, make #endifs match.
3554 * valarith.c (value_less): Handle unsigned int comparisons.
3555 Add FIXME about pointer compares, which assume host and target
3556 pointers are the same.
3558 * command.c (do_nothing_command): lint
3559 dbxread.c: lint. Remove sort_syms. Document C++ visibility info,
3560 fix comments on debug symbol format for visibility. Actually set
3561 visibility of symbols.
3562 main.c (echo_command): lint; use <readline/history.h>.
3563 tm-sparc.h (FRAME_FIND_SAVED_REGS): lint
3564 obstack.h (_obstack_blank): Rearrange pointer math to avoid
3565 pointing past end of allocated memory; saber complains.
3566 obstack.h: Declare the external functions that we use.
3567 valarith.h: use <string.h>
3568 solib.c (solib_add): lint.
3570 Fri Sep 21 17:05:19 1990 John Gilmore (gnu at cygint)
3572 * main.c (initialize_main): Default info_verbose to off, now that
3573 symbol reading is fast.
3574 (quit_command): Avoid clobbering exec_bfd while quitting.
3576 * Initial BFD (binary file diddling library) merger:
3577 coffread.c: Change AOUTHDR to struct exe_hdr.
3579 core.c: initialize initialized data at compile time.
3580 (core_file_command): Move from coredep.c, convert to bfd.
3581 (xfer_core_file): Convert to bfd.
3582 exec.c (exec_file_command): use bfd routines.
3584 mips-tdep.c: Remove exec_file_command and friends.
3587 * coredep.c: (fetch_core_registers) Convert core_file_command to
3588 fetch_core_registers.
3589 mips-xdep.c, sparc-xdep.c, sun3-xdep.c: ditto.
3591 * utils.c: (error): Bogus crap, FIXME, to print bfd errors.
3592 (my_bfd_read): More bogosity, which I don't think we call.
3593 (program_name): Remove this atrocity asap!
3595 Wed Sep 19 13:36:41 1990 John Gilmore (gnu at cygint)
3598 values.c: allocate_repeat_value was not clearing the
3599 optimized_out field.
3600 (value_static_field): minor stylistic fix (wrong macro was used).
3601 valops.c (value_struct_elt_for_address): didn't work for C++
3604 * signame.c (_initialize_signame): Initialize signal names once.
3606 * breakpoint.h, command.c, copying.awk, defs.h, environ.c,
3607 exec.c, frame.h, infcmd.c, inferior.h, main.c, munch, sun3-xdep.c,
3608 symtab.h, tm-29k.h, valprint.c, value.h, values.c: Lint.
3610 * remote-eb.c: Support user-settable baud rates on the serial port.
3612 * tm-sun3.h (PREPARE_TO_STORE): fix typo.
3614 Fri Sep 14 13:28:29 1990 John Gilmore (gnu at cygint)
3616 * tconfig/sun3os4: Remove warning about native assembler,
3617 since it also occurs in the xconfig file.
3619 * findvar.c (registers): Allocate some slop after `registers'
3620 to prevent stray accesses from trashing the next variable.
3622 * tm-68k.h (REGISTER_BYTES): Allocate the right number of bytes
3623 on the sun-3, by changing the #ifdef from `sun3' (which is not
3624 defined by cc) to `sun'. Symptom was trashed builtin_type_XXX
3625 vars, which happened to follow `registers' in the executable.
3627 * readline/history.c (history_search): Heed gcc-2's advice
3628 and parenthesize && inside ||).
3630 * am29k-opcode.h, am29k-pinsn.c, am29k-tdep.c, remote-eb.c,
3631 tm-29k.c: Insert FSF copyright headers.
3633 * remote-eb.c: Better comments.
3635 * Makefile.dist: Update to 3.91.6.
3636 * TODO: note PREPARE_TO_STORE problem.
3638 Thu Sep 13 09:52:33 1990 Jim Kingdon (kingdon at cygint)
3640 * stack.c (frame_info): Only use FRAME_FIND_SAVED_REGS if defined.
3642 * remote.c: Wrap the whole file in #if !defined (SPECIAL_REMOTE).
3644 * infrun.c (wait_for_inferior, at end): Don't set up
3645 prev_* if the inferior no longer exists.
3647 * inferior.h (CALL_DUMMY_LOCATION): New macro, to replace
3648 CANNOT_EXECUTE_STACK.
3649 valops.c (call_function): Use it.
3651 * tm-convex.h: Add CALL_DUMMY_LENGTH for use by PC_IN_CALL_DUMMY.
3653 * inferior.h (PC_IN_CALL_DUMMY): New macro.
3654 infrun.c (wait_for_inferior, 2 places): Use it.
3656 * values.c (value_being_returned): Only use
3657 EXTRACT_STRUCT_VALUE_ADDRESS if defined.
3659 * Move PREPARE_TO_STORE from xm-sun3.h to tm-sun3.h to do the
3660 right thing for remote-eb.c.
3662 * sun3-xdep.c: Remove extraneous call to remote_store_registers.
3663 * sun386-xdep.c, hp300hpux-xdep.c, sparc-xdep.c: Ditto.
3665 * blockframe.c: Put get_frame_saved_regs inside #if !defined
3666 (FRAME_FIND_SAVED_REGS).
3668 * findvar.c ({fetch,store}_registers): Check for
3669 REMOTE_{FETCH_STORE}_REGISTER macro.
3671 * findvar.c (get_saved_register): Add argument lval and
3672 change meaning of argument addr.
3673 findvar.c: Change calls to get_saved_register to reflect
3674 new calling convention.
3675 valops.c (value_assign): Use get_saved_register instead of
3676 find_saved_register.
3678 Sun Sep 2 12:40:20 1990 Jim Kingdon (kingdon at cygint.cygnus.com)
3680 * coffread.c (read_one_sym): Make temp_aux an AUXENT, not
3681 an (uninitialized) pointer to one. Use "&" when passing it
3684 Fri Aug 31 22:57:54 1990 Jim Kingdon (kingdon at cygint.cygnus.com)
3686 * coffread.c (getfilename): Use DGUX x_offset and x_name if
3689 * coffread.c (symbol_file_command): Put semicolon after
3691 Put safe_to_init_tdesc_context in #if defined (TDESC).
3692 Put #ifdef TDESCs in 1st column for non-ANSI cpp's.
3693 coffread.c: #include <sys/stat.h>.
3694 (read_coff_symtab): Typo: in_source_files -> in_source_file.
3695 Add missing ')' in check for "lc%" and friends. Remove
3697 Declare read_one_sym() at top of file.
3698 (read_file_hdr): Put in extra #ifdefs so MC68MAGIC and
3699 MC68WRMAGIC can have the same value without causing a duplicate
3702 Thu Sep 13 15:55:36 1990 John Gilmore (gnu at cygint)
3704 * Allow a Makefile to be built without building the
3705 tm and xm file links that screw up builds in subdirectories.
3706 This is done with `config.gdb none', then you can do things
3707 like `make gdb.tar.Z'.
3708 * tconfig/none: Config file for no target system
3709 * xconfig/none: Config file for no host system
3710 * config.gdb: If no TM or XM files are called out by the
3711 host or target file, don't make links for them.
3713 * cplus-dem.c: Add documentation.
3715 * dbxread.c (read_ofile_symtab): Turn a fatal error into a
3716 simple error, so the user's gdb doesn't crash due to some object
3717 file problem (e.g. somebody is rebuilding the file out from under
3720 * printcmd.c (print_address_symbolic): demangle the symbol.
3722 * Makefile.dist (OTHERS): Remove tdesc-lib because it has
3723 Motorola copyrights in it. Make "make gdb.tar.Z" work.
3724 (alldeps.mak): sort and uniq all results from this; duplicates
3725 hose gdb.tar.Z link building. Remove RCS files from
3726 tconfig and xconfig. Add config files for sun386. Add
3727 a few odd files to OTHERS and HFILES.
3729 Mon Sep 10 21:20:24 1990 John Gilmore (gnu at cygint)
3731 * Makefile.dist: Pull solib.c to tconfig/sun?os4.
3732 Roll version number to 3.91.5. Make lint work in bindir.
3734 * README: Document cross-debugging and new file structure.
3736 * blockframe.c: Lint. Include "value.h" to declare read_register.
3737 (find_pc_partial_function): remove duplicate line.
3739 * command.h: Lint. Declare error_no_arg and dont_repeat.
3741 * tm-news.h: Remove inadvertently duplicated stuff.
3743 * mipsread.c: Remove cache_pc_function stuff, now done cleanly.
3744 Clean up usage of misc_function_type. Declare some CORE_ADDRs.
3746 * config.gdb: Allow `config.gdb host target' form. Clean
3747 up previous change that printed bogus messages when you just said
3750 * core.c: #include "command.h" for lint.
3753 * main.c: Remove some casts of enums. Lint.
3760 * printcmd.c (initialize_printcmd): Fix thinko in inspect cmd.
3762 * sparc-tdep.c (isannulled): Take instruction as parameter, don't
3763 read it from memory. This will allow us to save ptrace calls
3764 eventually. Changed caller single_step too.
3766 * sparc-xdep.c (fetch_inferior_registers): Avoid reading regs
3767 that we aren't going to use, saving many ptrace calls, especially
3768 when watchpointing or single stepping. Use some #define's for
3770 (store_inferior_registers): Ditto.
3771 (core_file_command): Use some #define's for constants.
3773 * tm-sparc.h: Add #define's for some register numbers, so we
3774 can eliminate the use of random constants in sparc-xdep.c.
3776 * stack.c (frame_command, print_frame_info, up_command,
3777 down_command) Remove frame_changed, since it
3778 causes a bug and doesn't seem to do anything useful. In some
3779 places it was used as a flag, in others as a stack level (?).
3781 * utils.c: Use MISSING_VPRINTF rather than HAVE_VPRINTF, so the
3782 default is to use the portable (vprintf) version rather than the
3784 * xm-news.h (MISSING_VPRINTF): Add.
3786 * valprint.c (val_print): Demangle fancy vtbl printouts. Lint.
3788 Sat Sep 8 00:24:12 1990 John Gilmore (gnu at cygint)
3790 * Remove stuff that forces -Bstatic linking of gdb, and warnings
3791 about linking debugged programs -Bstatic in the sun?os4 config
3792 files in tconfig and xconfig subdirectories.
3794 * main.c (main): Remove unreached exit(0) now that we exit
3797 * Create TODO file for online bug list. There are too many
3798 "little" bugs to keep track of on paper.
3800 * Change Projects file to refer to bug-gdb@cygnus.com
3801 rather than kingdon@ai.
3803 Fri Sep 7 23:35:15 1990 John Gilmore (gnu at cygint)
3805 * Makefile.dist (VERSION): 3.91.4 now.
3807 * symtab.c (init_misc_bunches): Rename from init_misc_functions.
3808 (condense_misc_bunches): Add sanity check that misc_count is
3809 the same as the number of symbols in the bunch.
3811 * coffread.c: rename init_misc_bunches. Pass an argument
3812 to condense_misc_bunches (a zero).
3814 * dbxread.c (partial_symbol_file_read): Call init_misc_bunches
3815 every time we are called; don't rely on our caller to do it.
3816 (add_file): Remove call to init_misc_bunches.
3818 * mipsread.c: Only warn, don't error, if unknown symbol types.
3819 This keeps an old gdb from falling on its face if it sees newly
3820 extended symbol info. Rename init_misc_bunches.
3822 Fri Sep 7 22:58:15 1990 John Gilmore (gnu at cygint)
3824 * Merge in changes from Per Bothner for DECstations and other
3825 MIPS stuff. The rest is Bothner speaking:
3827 The next message is a merger of Alessando Forin's mips port with
3828 mine. I've tried to use my good if biased judgment to get
3829 the best of both. It *does* need testing.
3831 Some of the changes are general, *not* mips-specific.
3834 Didn't believe in little-endian bit order.
3835 There are still inconsistencies about whether flags
3836 like BITS_BIG_ENDIAN are integer (#if ...) or
3837 boolean (#ifdef ...). I tried to paper over them.
3839 dbxread.c,coffread.c,mipsread.c,symtab.c,symtab.h:
3840 Moved some misc_function code that was common to
3841 {dbx,coff,mips}read.c to symtab.c.
3842 In the process, I think I cleaned things up a bit.
3843 At the same time, moved obsavestring and obconcat to symtab.c.
3846 Removed obsolete condense_addl_misc_bunches (use
3847 condense_misc_bunches(1) instead).
3850 Needed to include <sys/dir>, at least on DECstations.
3852 valops.c, mips-tdep.c, tm-mips.h:
3853 Added PUSH_ARGUMENTS macro to support funny argument-pushing
3854 conventions (when STACK_ALIGN is insufficient).
3855 Needed on mips, where doubles need 8-byte alignment,
3856 but ints only need 4.
3859 Removed cruft that was not being used.
3860 Merged in many fixes (most from Frank Yellin, fy@lucid.com).
3863 Print $ before register-names (I think that makes things a little
3865 Never print two instructions, even if one delays.
3866 Removed hex-disassemble set_cmd. (This is not mips-specific,
3867 so I think the argument is whether it is generally worthwhile or not.
3868 I'm inclined to think not, given how easy it is to
3869 convert between radixes in gdb.)
3872 This is basically Alessando's code.
3873 It doesn't use obstacks; I changed it to use obstacks
3874 in a few minor places where using malloc causes a
3875 memory leak. (Probably, more places could/should be changed.)
3876 I added record_misc_function where it was missing.
3877 In symbol_file_command and add_file_command, I tried
3878 to make the code consistent with more recent versions.
3879 Minor sylistic changes in parse_procedure.
3880 Make a .gdbinfo. psuedo-symbol point back to the real
3881 procedure symbol (using the isym field).
3884 This is basically from my port, but with a lot of details
3885 and a number of routines merged in from Alessando's version.
3886 I basically used my code "raw" backtrace (use heuristics
3887 from the actual code, rather than symbol table info) - though
3888 the idea is Alessandro's. I feel my code is a little cleaner
3889 here, particularly in being a little more flexible, such as being
3890 able to handle gcc-produced code (which it now can).
3891 It also doesn't do frame caching (which is not useful
3892 more recent gdb versions).
3893 I also used my code for push_/pop_dummy, more or less.
3894 I tried to incorporate AF's code for testing sigtramp
3895 while backtracing; I probably got it wrong.
3896 Added mips_print_register, which tries to scrunch as much
3897 information as possible on a screen...
3898 Removed the skip-prologue set_cmd. As with hex-disassemble (see
3899 under mips-pinsn.c), I don't see anything mips-specific here,
3900 and I don't see it being all that useful anyway.
3903 Added a $fp psuedo-reg distinct from $fp (nice for gcc).
3904 Use more register names (rather than hard-cases numbers).
3906 Thu Sep 6 18:33:15 1990 John Gilmore (gnu at cygint)
3908 * Hack up 3.90.11 changes:
3910 * Makefile.dist (depend): parameterize $(GCC).
3911 Add solib.c and solib.o.
3912 (readline): Fix vpath for both absolute or relative SRCDIR.
3914 * blockframe.c: Fix from Schaefer@asc.slb.com for shared libs.
3915 Also, let the part I didn't understand at least compile so
3916 I can test the rest. FIXME.
3918 * dbxread.c: Fix thinko using strcmp.
3919 (init_psymbol_list): declare static.
3920 (partial_symbol_file_open): Comment cleanups better, avoid
3921 cleaning up the string table since the caller will do that.
3922 Move the stat for mod time into symbol_file_command, temporarily.
3923 (There should be a mod time for each symbol file, eventually,
3924 to control its rereading. FIXME.)
3926 * infptrace.c (PT_WRITE_D): use same value as PT_WRITE_I for
3927 SunOS, which gives error for shared libs otherwise. (From
3928 Schaefer, probably FIXME needs work for portability.)
3930 * solib.c: Move #include "param.h" to work.
3931 Lowercase all the Uppercase Letters In the Messages.
3932 (find_solib): Clean up inferior_so_name for debug printouts.
3933 Allow no argument, to mean all shared libraries.
3935 * symmisc.c: include param.h to get CLEAR_SOLIB.
3937 Wed Sep 5 18:00:08 1990 John Gilmore (gnu at cygint)
3939 * Merge in Kingdon's changes from FSF: the diffs from 3.90.9
3940 to 3.90.11. ChangeLog entries below are from this.
3942 Wed Jun 13 09:17:39 1990 Jim Kingdon (kingdon at mole.ai.mit.edu)

3948 Tue Jun 12 16:15:26 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
3952 * Makefile.dist (gdb.tar.Z): Change linking of config so it works.
3954 Thu Jun 7 16:22:27 EDT 1990 Jay Fenlason (hack@ai.mit.edu)
3956 * sparc-opcode.h Added single-operand version of rett.
3958 Mon Jun 4 18:12:31 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
3960 * m-sparc.h (REG_STRUCT_HAS_ADDR, STRUCT_ARG_SYM_GARBAGE):
3961 Put parens around gcc_p in expansion.
3963 Thu May 24 15:44:51 1990 Jim Kingdon (kingdon at mole.ai.mit.edu)
3965 * utils.c (lines_to_list): Return 10 if lines_per_page == 0.
3967 Wed May 23 16:36:04 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
3969 * Changes for Sun shared libraries:
3970 blockframe.c (find_pc_partial_function): If a non-text symbol
3971 is found, set *address = pc - FUNCTION_START_OFFSET.
3972 breakpoint.c (insert_breakpoints) [DISABLE_UNSETTABLE_BREAK]:
3973 Disable breakpoints instead of giving an error.
3974 source.c (select_source_symtab): Initialize cs_pst.
3975 symmisc.c: Call CLEAR_SOLIB if defined.
3976 symtab.h: Make text{low,high} CORE_ADDR not int.
3977 (psymtab): New field addr.
3979 dbxread.c: Move DECLARE_FILE_HEADERS outside functions.
3980 (record_misc_function): Give correct type for N_DATA symbols.
3981 (condense_misc_bunches): do "misc_function_count = j" regardless
3983 Take code which is shared between symbol_file_command and
3984 add_file_command and put it into partial_symbol_file_{open,read}.
3985 Split add_file_command into add_file_command and add_file.
3986 Make psymtab_to_symtab read in the string table if the file
3988 Two new parameters to read_dbx_symtab and start_psymtab.
3989 tm-sunos.h: New file.
3991 Tue May 22 17:43:03 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
3993 * infcmd.c: Change cont_command to continue_command and "cont"
3996 Mon May 21 14:41:41 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
3998 * breakpoint.c (enable_breakpoint): Get value of watchpoint.
4000 * defs.h [sparc]: Use <alloca.h> regardless of __GNUC__.
4002 * values.c (USE_STRUCT_CONVENTION): Check for structures of
4003 size 1,2,4,8 rather than size < 8.
4005 * dbxread.c (dbx_lookup_type): Do f->length *= 2 as many times
4006 as necessary, not just once.
4008 * sparc-opcode.h: Add a bunch of new opcodes which Sun as supports.
4010 Thu May 17 15:04:09 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
4012 * {t,x}m-sun386.h, sun386-xdep.c, {x,t}config/sun386
4014 * tm-news.h: Add CALL_DUMMY_*.
4016 * tm-68k.h: Remove duplicate comment at FRAME_FIND_SAVED_REGS.
4018 * config.gdb: In list_host, list_target, use ${i}, not $i.
4020 Tue May 15 21:27:12 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
4022 * source.c (find_source_lines) [BROKEN_LARGE_ALLOCA]: Use xmalloc.
4024 * sparc-opcode.h: Change all store floating-point state register
4025 instructions to have the right match & lose fields.
4027 Sat May 5 12:39:18 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
4029 * Makefile.dist: Move -I${srcdir} to GLOBAL_CFLAGS and pass
4031 config.gdb: If srcdir != ., create readline directory and
4032 copy a makefile into it.
4034 * wait.h, infrun.c: Change WRETCODE to WEXITSTATUS for
4035 consistency with POSIX.
4037 * breakpoint.c (bpstat_stop_status): Disable watchpoint
4038 when we exit its exp_valid_block.
4040 Tue Sep 4 11:46:46 1990 John Gilmore (gnu at cygint)
4042 * Makefile.dist: Bump version to 3.91.3.
4044 * Clean up handling of breakpoint commands (somewhat).
4045 Prompted by Tiemann bug report "cont 10" doesn't work any more.
4047 inferior.h: Add breakpoint_proceeded to inferior status struct
4048 and globals; save it and restore it.
4049 (clear_breakpoint_commands): Cleanup, remove old #define.
4051 infrun.c (clear_proceed_status): Set breakpoint_proceeded.
4052 (save_inferior_status, restore_inferior_status): handle it also.
4053 (proceed): Remove earlier code that set breakpoint_proceeded.
4054 It is now set only in clear_proceed_status.
4055 (clear_proceed_status): Cleanup, use bpstat_clear rather
4056 than clear_breakpoint_commands. No callers need the stop_bpstat
4057 between clear_proceed_status and proceed.
4059 infcmd.c: Add breakpoint_proceeded definition and comment.
4060 (cont_command, jump_command, signal_command): Move call to
4061 clear_proceed_status right next to call to proceed.
4063 breakpoint.c (bpstat_do_actions): Avoid clobbering our
4064 caller's argument while running down the chain of breakpoints.
4065 Use new variable "breakpoint_proceeded" to determine when
4066 a command that it executes moves the inferior past the
4068 (bpstat_clear): Handle NULL argument.
4069 (bpstat_clear_actions): Avoid useless call to
4070 breakpoint_auto_delete.
4071 (delete_breakpoint): Clean up bpstat's that are pointing to
4072 the deleted breakpoint from the stop_bpstat chain.
4073 (breakpoint_auto_delete): Simplify.
4075 * Clean up handling of EOF, error on stdin, etc. This was
4076 prompted by a network problem that caused gdb to go into an
4077 infinite loop filling up its malloc'd memory.
4079 main.c (return_to_top_level): Cleanup: call bpstat_clear_actions,
4080 not clear_breakpoints_commands, which is now gone.
4081 (main): If command_loop returns (e.g. from EOF on stdin), do
4082 a quit_command (looping back to command_loop if quit_command
4083 doesn't really quit).
4084 (command_loop): check result from command_line_input and
4085 exit if it returns NULL, rather than passing the NULL to
4087 (gdb_readline): Free malloc'd result space before returning
4090 * utils.c (query): Handle C-d to mean "yes", just as if the
4091 input was not a terminal. Also avoid infinite loop if EOF
4092 occurs in mid-input-line before newline. This allows
4093 query to be used at EOF on stdin with reasonable results.
4095 * infrun.c (proceed): Set breakpoint_proceeded.
4097 * values.c (value_as_long): Avoid infinite recursion for enums.
4098 (_initialize_values): Fix typo in help msg (kingdon).
4100 * Makefile.dist (RL_LIB): Use RL_LIB_DEP for dependencies,
4101 RL_LIB for linking. This allows -lreadline for linking
4102 and nothing for dependencies, once readline is a real library.
4104 * config.gdb: Jim Kingdon: give useful error message if the
4105 host or target type is not recognized.
4107 * defs.h (alloca): SPARC <alloca.h> does not declare alloca,
4108 it just defines it. Dumb, but deal with it.
4110 * Jim Kingdon suggests:
4111 in xconfig/sun3os4, CFLAGS should be XM_CFLAGS.
4113 Wed Aug 29 18:03:27 1990 John Gilmore (gnu at cygint)
4115 * Makefile.dist (VERSION): Bump version # to 3.91.2.
4117 * Clean up Bothner's changes.
4119 * blockframe.c (clear_pc_function_cache): New function.
4120 * blockframe.c: remake cache_pc_function_* static.
4121 * dbxread.c (symbol_file_command): remove references to
4122 cache_pc_function_* variables.
4123 * dbxread.c (read_struct_type): Use VOFFSET_STATIC.
4124 * printcmd.c: Avoid kludging a global variable (addressprint)
4125 to avoid printing the address of a string twice. Instead,
4126 pass the format letter 's' down low enough that it can be seen
4127 to avoid this problem.
4128 (print_formatted): Pass format arg to value_print.
4129 (restore_addressprint): Remove function.
4130 (do_examine): Avoid hacking addressprint, cleanups and such.
4131 (print_frame_args): Add a comment to a Bothner change.
4132 * symtab.h: define VOFFSET_STATIC and use it instead of "-1".
4133 * symmisc.c (free_all_symtabs): Call clear_pc_function_cache
4134 to wipe out the values cached in blockframe.c.
4135 * symtab.c (find_method): Add comment saying how big you must
4136 allocate to be "big enough". Per being terse again.
4137 * valprint.c (val_print): Handle format letter "s" to print
4138 strings without addresses. Add comment to vtbl printing code
4139 which casts with wild abandon. Rearrange reference-printing
4141 @0xaddr: value (print w/addressprint)
4142 value (print w/~addressprint)
4143 @0xaddr (parameter lists w/addressprint)
4144 or nothing (parameter lists w/o addressprint)
4146 Tue Aug 28 10:47:18 1990 John Gilmore (gnu at cygint)
4148 * Merge more changes from Per Bothner:
4150 Gdb's handling of TYPE_CODE_REF was so counter-C++ (and otherwise
4151 annoying) that I tried to improve it. Here are my suggestions.
4153 These patches all attempt to handle TYPE_CODE_REF (as in C++) better.
4156 Do automatic de-reference when taking the address of a reference.
4158 Don't deref_ref when printing parameter lists.
4160 More attempts at treating refernences properly.
4162 In val_print, if deref_ref==0, don't print dangling " = ".
4164 Add COERCE_REF macro, which de-references an REF.
4166 * Merge changes from Per Bothner:
4168 * Fixed (Sony news)-specific configuration problems.
4169 * Fixed other problems with using vanilla pcc and libc (enum problems;
4170 assumption that vsprintf exists).
4171 * Some major speed-ups (finc_pc_partial_function now caches a match;
4172 parsing avoids duplicate symbol_lookup calls).
4173 * Changed handling of baseclasses (no longer use baseclasses field
4174 of struct type, use the first n_baseclasses fields instead).
4175 * Various minor changes/fixes, most C++-related.
4178 Cache the most previous match from find_pc_partial_function.
4179 (Save both low and high ends of matching function's pc range.)
4180 This speeds up the loop of infrun.c:wait_for_inferior quite
4181 a bit, and makes step/next commands much zippier.
4183 Added an enum->int cast (otherwise, some compilers barf).
4185 No longer set baseclass offset to 0, since multiple
4186 inheritance now mostly works.
4187 Added a number of casts, to shut up compiler warnings
4188 (after stabs where made enums, not ints).
4189 When discarding a symbol table (in symbol_file_command),
4190 must clear the cache introduced in blockframe.c.
4191 Don't convert $vtbl_ptr_type to vtbl any more.
4192 Get rid of TYPE_BASECLASEES and baseclass_vec (see also symtab.h).
4193 Mask off sign bit emitted by g++ for virtual table offset.
4194 Set voffset to -1 (not 1) for static member functions.
4196 Changed parsing/lexing of names to avoid doing symbol lookup twice
4197 (once when lexing to determine symbol class, once for real).
4198 Now only call symbol_lookup once. Fields of 'this' win especially big.
4200 Subpress printing addr twice in the case of 'x/s addr'.
4202 lookup_basetype_type is no longer used.
4203 Add find_methods as recursive helper function to decode_line_1.
4204 This allows multiple inheritance to work.
4205 Also, once one or more matches has been found, do not look in
4206 base-classes. (Baseclass methods would be overridden, anyway.)
4208 Removed baseclasses array in struct type.
4209 Instead of using baseclasses[i], use fields[i-1].
4210 Added virtual_field_bits[i] to indicate if the i'th baseclass is virtual.
4211 Changed sign convention of voffset (previous was inconsistent).
4213 Some macros (CALL_DUMMY and relatives) were missing. Put them back.
4215 Used to assume existence of vsprintf. Re-written to not need it
4216 if HAVE_VPRINTF is undefined.
4218 typecmp was too pessimistic. Made it less so.
4220 Don't print space after address.
4221 If vtable points to a misc symbol (with 0 offset), print it,
4222 since that indicates the actual class of the object.
4223 Changed ype_print_derivation_info to use new inheritance
4224 scheme (without baseclasses vector).
4226 In value_primitive_field, fixed some bugs left over from previous set of fixes.
4227 Also, changes needed because TYPE_BASECLASSES were removed.
4229 REGISTER_U_ADDR didn't work for PC. Rewrote to use an array.
4231 Tue Aug 21 20:08:54 1990 John Gilmore (gnu at cygint)
4234 If there is no path set, and the symbols don't indicate what directory
4235 a file was compiled in, look in the current directory. But either
4236 a path or a known compilation directory will prevent this.
4239 Three independent bug fixes:
4240 * Remove the #if 0 block that breaks some stuff.
4241 * SunOS 4.1 fixed the promoted-parameter-wrong-addr bug in Sun C;
4242 adapt gdb to either SunOS 4.0.* or 4.1.
4243 * MAX_OF_TYPE and MIN_OF_TYPE thinko. By tedg@sun, I think.
4246 Instantiate the class T when looking for methods in it. (Tiemann@sun)
4249 (type_print) Demangle the name being printed.
4250 (type_print_base) Handle botched demangling without coredump (tiemann).
4253 (check_stub_method): Document routine.
4254 (tiemann) fix bug for no-arg functions
4255 Avoid clobbering beyond end of malloc'd storage.
4256 Terminate the argument list properly.
4258 Sat Aug 18 01:29:59 1990 Per Bothner (bothner@cs.wisc.edu)
4260 * Changes merged by John Gilmore:
4263 In breakpoint_1, use new print_address_symbolic instead
4264 of find_pc_partial_function. (This forces use of assembler-level
4265 addresses, and avoids misleading non-mangled source-level names.)
4267 Generalize ansi argument such that -1 means skip arglist totally.
4268 Removed global variable print_ansi_qualifiers (which made
4269 code non-reentrant), in favor of extra explicit arguments
4270 to internal routines.
4272 Add new helper function print_address_symbolic.
4273 Use find_pc_misc_function instead of find_pc_partial_function
4274 (since we want assembler-level symbols here).
4276 Print unknown function as just "f (...)", not "f (...) (...)".
4277 Use new fputs_demangled explicitly.
4279 Fixed a typing violation (problem: value.h cannot be imported
4280 without renaming many variable in this file).
4281 lookup_symbol: If no matching misc_func, look for a C++-mangled name.
4282 decode_line_1: Moved forward some never-reached code.
4283 Made decode_line_2 skip function prologues correctly.
4285 fputs_filtered should not demangle by default.
4286 Add new fputs_demangled to demangle on demand..
4288 Change value_struct_elt to use value_primitive_field (using recursive
4289 utility function search_struct_field). This allows foo.bar to work
4290 for multiple inheritance (so far only for data fields).
4291 Change check_field in the same way (recursive helper function
4292 to support multiple inheritance).
4293 (Note: there are more of these problems that I haven't fixed.
4294 Any code that says TYPE_BASECLASS (t, 1) is probably wrong.)
4295 value_of_this: 'this' symbol name is now just "this", note "$this".
4297 Don't print static members.
4298 Avoid printing "members of <type>" if there are none.
4299 Simplified type_print_derivation_info by merging duplicate code.
4300 Remove useless blank lines in type_print_base (ptype command).
4302 Added declaration of new routine value_primitive_field.
4304 Added value_primitive_field which is generalized version of
4305 value_field that can handle multiple inheritance (non-zero offsets etc).
4306 Re-implemented value_field to call value_primitive_field.
4308 Fri Aug 17 23:33:44 1990 John Gilmore (gnu at cygint)
4310 * infcmd.c -- insert else to avoid 'delete env' coredump when you
4311 delete the whole environment. Karl Berry reported the bug.
4312 * source.c - fix openp to avoid //'s in filenames, which
4313 trigger an Emacs bug causing it to not be able to find files
4314 when running gdb in a window.
4315 * dbxread.c - zap the #if 0 that botches the add-file code.
4316 It seems to work a lot better without all the code commented out.
4318 Fri Jul 20 16:58:46 1990 John Gilmore (gnu at cygnus.com)
4320 * Merge Tiemann's and Ted Goldstein's changes, detailed below,
4323 Tue Jul 17 19:34:33 1990 Ted Goldstein (tedg at golem)
4325 * Makefile - added a ${CFLAGS} to a couple of entries,
4326 added remote-sa.sparc.c
4327 * added remote.sa-sparc.c, a modification of remote.c
4328 which conducts a dialog directly with the SparcStation prom.
4329 * breakpoint.c, infrun.c, sparcdep.c added
4330 remote_insert_breakpoint(), and remote_remove_breakpoint()
4331 to breakpoint.c instead of directly writing breakpoint instructions.
4332 * sparcdep.c on remote_debugging,there is no need
4333 to remove signle step breakpoint instructions.
4334 * main.c added "-epoch" flag and "int epoch_interface" to main.c
4336 * printcmd.c - epoch interface sends lisp expressions to open up
4337 epoch windows on inspection.
4338 * valprint.c - added arrayprint, and addressprint and made adding
4339 format controls easier
4340 * wait.h added a couple of undef's because we were getting
4341 complaints about WSTOPSIG and WTERMSIG begin redefined.
4344 Wed Jul 4 05:27:51 1990 Michael Tiemann (tiemann at masham)
4346 * symtab.c (decode_line_1): Add support for handling method stubs
4347 in the type information.
4349 Tue Jul 3 09:39:18 1990 Michael Tiemann (tiemann at masham)
4351 * values.c (baseclass_addr): Run loop from INDEX+1 to
4352 N_BASECLASSES; otherwise, we can still get into a loop.
4353 @@ This should be restructured to use a cleaner search strategy.
4355 Sun Jul 1 12:28:51 1990 Michael Tiemann (tiemann at masham)
4357 * dbxread.c (define_symbol,read_type): Grok GNU C++'s new
4358 abbreviation "Tt" for tags which have the same name as their
4361 Fri Jun 29 01:03:46 1990 Michael Tiemann (tiemann at masham)
4363 * symtab.c (list_symbols): add ability to set breakpoints on all
4364 the functions which match a particular regular expression.
4366 Tue Jun 26 04:26:29 1990 Michael Tiemann (tiemann at masham)
4368 * cplus-dem.c (cplus_demangle): New parameter ANSI says whether we
4369 should print ANSI qualifiers (such as `const' and `volatile').
4370 All callers changed to call with ANSI == 1, except from
4371 `check_method_stub', which uses old-style syntax.
4373 * symseg.h (struct fn_field): Remove unneccessary `args' field.
4374 * symtab.h (TYPE_FN_FIELD_ARGS): Redefined.
4376 * values.c (check_stub_method): New function.
4378 * cplus-dem.c (do_type): Handle "long long" (encoded as 'x').
4380 * dbxread.c (read_type): Handle new GNU C++ method type stubs.
4381 * valprint (type_print_base): Ditto.
4383 * symtab.c (gdb_mangle_typename): New function.
4385 Tue Jun 5 00:18:43 1990 Michael Tiemann (tiemann at gzilla)
4387 * breakpoint.c (catch_command): New function. Provides a
4388 mechanism to set breakpoints based on catch clauses.
4389 (disable_catch): Similar, but disables breakpoints on catch
4391 (delete_catch): Similar, but deleted breakpoints on catch clauses.
4393 Sun Jun 3 22:54:08 1990 Michael Tiemann (tiemann at gzilla)
4395 * blockframe.c (blockvector_for_pc): New function.
4396 * blockframe.c (block_for_pc): Changed to call
4397 `blockvector_for_pc' and get the block itself.
4399 * stack.c (catch_info): New function. Prints info about
4400 exceptions which can be caught in the current frame.
4401 * stack.c (print_frame_label_vars): New function. Similar to
4402 `print_frame_local_vars'.
4403 * stack.c (print_block_frame_labels): Prints out labels that are
4404 defined in this frame. These labels are exceptions that can be
4407 * dbxread.c: Updated to handle N_CATCH symtab types.
4409 Thu May 3 22:10:00 1990 Michael Tiemann (tiemann at teacake)
4411 * valprint.c (everywhere): TYPE_NAME (TYPE) no longer comes in the
4412 form "struct ..." for GNU C++. Don't flush any part of TYPE_NAME
4413 when printing the type.
4415 Wed May 2 22:43:04 1990 Michael Tiemann (tiemann at teacake)
4417 * valprint.c (val_print): Use `baseclass_addr' to access the
4418 baseclasses pointed to via the derived class object at VALADDR.
4420 * values.c (baseclass_addr): New function. Casts derived pointers
4421 to baseclass pointers taking virtual baseclasses and multiple
4422 inheritance into account.
4424 Sat May 5 12:39:18 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
4428 Fri May 4 12:12:55 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
4430 * breakpoint.c (watch_command, bpstat_stop_status): Deal with
4431 exp_valid_block field correctly.
4433 * infrun.c (wait_for_inferior): When checking "don't even think
4434 about breakpoints" if stop_signal == SIGTRAP && trap_expected,
4435 also check step_resume_breakpoint.
4436 Insert breakpoints and continue (not step) if
4437 step_resume_break_address != NULL, even if another_trap.
4438 If trap_expected and we enter sigtramp, then set up a
4440 If trap_expected is set when we hit the step_resume_break,
4442 When calling resume and trap_expected says tell resume to step
4443 (2 places), also check step_resume_break_address.
4445 * infrun.c (wait_for_inferior): Don't set
4446 prev_{pc,sp,func_{start,name}} before calling wait ().
4447 Do set them after exiting loop.
4448 Move their declarations outside functions.
4449 (start_inferior): Initialize them.
4451 Thu May 3 00:15:11 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
4453 * infrun.c (wait_for_inferior, after check for trap_expected > 1):
4454 Restore old code which distinguishes between trap_expected and
4455 running_in_shell, just make the latter take any non-TRAP signal,
4458 * values.c (allocate_value): Zero VALUE_OPTIMIZED_OUT flag.
4460 * Makefile.dist (pinsn.o): Use PINSN_CC to compile.
4461 xconfig/3b1 (CC,PINSN_CC): Define.
4463 * xconfig/altos, altos-dep.c: Rename altos-dep.c to altos-xdep.c.
4467 * breakpoint.c (bpstat_stop_status),
4468 infrun.c (wait_for_inferior) [SHIFT_INST_REGS]: New code.
4470 * param.h, tm-88k.h: Define ADDR_BITS_*.
4471 infcmd.c (jump_command, read_pc), infrun.c (wait_for_inferior),
4472 printcmd.c (do_one_display): Use them.
4474 * utils.c: Split #ifdef USG into a USG_UTILS and a QUEUE_MISSING.
4475 xm-88k.h: Define USG_UTILS.
4477 Wed May 2 00:05:33 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
4479 * printcmd.c (printf_command) [__INT_VARARGS_H]: New code.
4480 (printf_command): Add from_tty parameter.
4482 * valprint.c (value_print): Check VALUE_OPTIMIZED_OUT flag.
4484 * value.h: Add optimized_out field and change lazy field to
4485 char. Add macro VALUE_OPTIMIZED_OUT.
4487 * i386-pinsn.c: Change from Eirik Fuller to write to stream directly
4488 instead of stuffing things in buffers (oappend, etc).
4490 * breakpoint.c (bpstat_do_actions): If *BSP is set to NULL by
4491 execute_command, exit both loops.
4493 * Makefile.dist: Don't set TARGET_ARCH. Add .c.o rule.
4495 Tue May 1 17:07:23 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
4497 * Makefile.dist (RAPP_OBS, rapp),
