20 Fri Aug 23 11:46:08 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
22 * doc/gdb.texinfo: update, fix bugs in "Installing" appendix
24 Fri Aug 23 01:02:00 1991 John Gilmore (gnu at cygint.cygnus.com)
26 * Makefile.in: Add config.sub, make doc/rdl-apps.texinfo for
27 tar file, add dependencies for referenced doc files.
29 Thu Aug 22 22:17:06 1991 Stu Grossman (grossman at cygint.cygnus.com)
31 * coffread.c, symfile.c, stack.c: saberized.
33 Thu Aug 22 16:20:27 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
35 * doc/refcard.tex: permuted Essential Commands sec
37 * doc/gdb.texinfo: new C++ chapter; revised installation appendix;
39 set/show symbol-reloading
40 default set complaints 0
42 RET-repeat disabled after prompted long displays
43 processID (attach) interpretation of 2nd GDB cmdline arg
45 Thu Aug 22 14:05:47 1991 Stu Grossman (grossman at cygint.cygnus.com)
47 * expread.y, coffread.c, dbxread.c, target.c, mem-break.c,
48 cplus-dem.c, values.c, valprint.c, symfile.c, remote.c,
49 breakpoint.c, main.c: lint.
51 Thu Aug 22 02:02:26 1991 John Gilmore (gnu at cygint.cygnus.com)
53 Install new configuration scheme for GDB and friends.
55 * config.sub: Translate ordinary names to three-part names.
56 * configure: Use three-part names internally.
57 * configure.in: Translate three-part names to filenames.
59 * README, WHATS.NEW: Update for gdb-4.0.
60 * Makefile.in: Roll VERSION to 3.99.
62 Wed Aug 21 18:21:09 1991 John Gilmore (gnu at cygint.cygnus.com)
64 * infptrace.c (KERNEL_U_ADDR_BSD): Include a.out.gnu.h.
65 * i960-tdep.c, m68k-tdep.c, sparc-tdep.c, tm-i960.h,
66 tm-m68k.h, remote-nindy.c: Change ext_format_XXX structs
67 to single structures rather than arrays; when passing
68 their address, use &. This avoids trouble with bdead compilers.
69 * mcheck.c: Don't include <stdlib.h>; just declare "void abort();"
70 instead. This avoids portability headaches.
71 * mips-tdep.c (mips_do_registers_info): Only print FP regs if
73 * source.c (open_source_file): Avoid ANSI const bdeath by
74 skipping declaration and then casting result value.
75 * tm-hp300bsd.h: Clarify comment.
76 * utils.c (strstr): Result is const char *; ANSI bdeath.
77 * xm-hp300bsd.h: Define HOST_BYTE_ORDER. Redefine INT_MIN,
78 since system include file defines it differently from "defs.h",
79 though the two are equivalent for our purposes.
80 * tconfig/hp300bsd: Add m68k-tdep.o.
82 Tue Aug 20 16:01:11 1991 John Gilmore (gnu at cygint.cygnus.com)
84 * tconfig/sun*4: Remove warnings about system assembler.
86 Mon Aug 19 13:44:46 1991 John Gilmore (gnu at cygint.cygnus.com)
88 * mcheck.c: Avoid warning about undeclared abort fn.
89 * tm-sparc.h (PC_ADJUST): Avoid calling error() from this;
90 it causes recursive calls to error() when used in cleanups.
91 To do so requires that we make it a function, so we do.
92 * sparc-tdep.c (sparc_pc_adjust): New implem of PC_ADJUST.
93 * utils.c (do_cleanups): Remove the current cleanup from the
94 chain *before* calling it, in case error() is called from it.
95 The result won't be pretty, but won't be an infinite loop either.
97 Mon Aug 19 00:41:04 1991 Michael Tiemann (tiemann at cygint.cygnus.com)
99 * dbxread.c (read_struct_type): Grok anon structs for C++.
100 (vb_name, vptr_name): Null terminate these strings.
102 Fri Aug 16 08:31:03 1991 John Gilmore (gnu at cygint.cygnus.com)
104 Minor bug fixes from BSD Net2 gdb:
106 * blockframe.c (get_prev_frame_info): If FRAME_CHAIN_COMBINE
107 returns 0, there is no previous frame.
108 * breakpoint.c (commands_command): If !from_tty, don't call
109 input_from_terminal_p().
110 * dbxread.c (record_misc_function): Speed up slightly.
111 (compare_psymbols): Ditto.
112 * infcmd.c (do_registers_info): Take a second argument to
113 determine whether to print float registers. "info registers"
114 does not do so anymore. "info all-registers" does, now.
115 * mips-tdep.c, pyr-tdep.c (xxx_do_registers_info): Take second
117 * tm-mips.h, tm-pyr.h (DO_REGISTERS_INFO): Pass second arg.
118 * inflow.c (initialize_inflow): Set tflags_ours correctly.
122 * breakpoint.c (bpstat_do_actions): Use a cleanup to restore
123 executing_breakpoint_commands if we are interrupted by error.
124 * coffread.c (init_lineno): Avoid problem with zero-sized linetab
125 versus malloc/free. From: john@labtam.labtam.oz.au (John Carey).
126 * core.c (solib_add_stub, core_open): Call SOLIB_ADD inside a
127 catch_errors() so we can setup the frame regardless of whether
128 the shared libs work.
129 * ieee-float.c (double_to_ieee_extended): Get exponent from
130 right place in little-endian systems. From John Carey.
132 Thu Aug 15 18:43:57 1991 John Gilmore (gnu at cygint.cygnus.com)
134 * main.c: Remove unused terminating_signals and catch_termination().
135 (long_options): Terminate with a zero element.
136 [Bugfix from Atsuo Kawaguchi <atsuo@hark86.harl.hitachi.co.jp>.]
137 (gdb_readline): Make call-compatible with readline.
138 (init_signals): Improve comments re vfork vs. signal.
140 * utils.c (prompt_for_continue): Use new gdb_readline().
141 If we prompt for continuation, we don't let CR repeat the previous
142 command, once we get back to a prompt. It's too easy to keep
143 hitting CR, expecting "--more--" prompts, and have some long
144 command start repeating on you.
146 Tue Aug 13 16:17:56 1991 John Gilmore (gnu at cygint.cygnus.com)
148 * blockframe.c (frameless_look_for_prologue): Speed up by
149 calling SKIP_PROLOGUE_FRAMELESS_P if it's defined.
150 * tm-sparc.h (SKIP_PROLOGUE, SKIP_PROLOGUE_FRAMELESS_P):
151 Define two variants, one faster.
152 * sparc-tdep.c (sparc_frame_chain): Use target_read_memory
153 and return zero, rather than giving an error.
154 (setup_arbitrary_frame): Initialize the PC in the new frame.
155 (skip_prologue): Add a second arg saying whether we're just
156 checking for a frameless function or not.
158 * core.c (core_open, core_close, core_xfer_memory): Move
159 section table pointers and bfd* into the target_ops.
160 (core_open): Allow errors in shared lib reading, etc.
161 (core_files_info): Describe shared library sections.
163 * exec.c (exec_open, exec_close, exec_xfer_memory, xfer_memory,
164 exec_files_info, set_section_command): Move section table
165 pointers and bfd* into the target_ops.
166 (add_to_section_table): Add BFD to section table.
168 * target.c (target_xfer_memory, target_info): Pass target to
169 xfer_memory and target_info functions.
172 * gdbcore.h: Move struct section_table.
173 * target.h: New home of struct section_table.
175 * solib.c (solib_add): New argument is the target_ops whose
176 section list is to be added to, if any. Reallocate the
177 sections in that target to add any that come from shared libs.
178 (throughout) so_sections renamed to sections.
179 (solib_xfer_memory): Deleted.
180 * tm-sunos.h (SOLIB_ADD): Add target argument.
181 (SOLIB_XFER_MEMORY): Delete.
183 * core.c, exec.c, inftarg.c, remote-eb.c, remote-nindy.c,
184 remote-vx.c, remote.c, target.c, target.h: Remove add_syms vector
185 from target_ops. It's the same on all targets. Add two section
186 pointers to target_ops.
188 * stack.c (find_relative_frame): Dump ancient algorithm for
189 "down", just use handy "next" pointers.
190 (frame_command): Don't error if there is no stack; let user
193 * inflow.c (new_tty_prefork, new_tty): New prefork routine
194 modifies static state in the parent process; new_tty itself
195 runs in the child and modifies the child's file descriptors
196 to match the saved static state.
197 * infrun.c (child_create_inferior): Call new_tty_prefork,
200 * infptrace.c (child_xfer_memory): Add ignored target arg.
201 * remote-eb.c (eb_xfer_inferior_memory): ''
202 * remote-nindy.c (nindy_xfer_inferior_memory): ''
203 * remote-vx.c (vx_xfer_memory): ''
204 * remote.c (remote_xfer_memory): ''. Rename from
205 remote_xfer_inferior_memory.
207 * main.c (main): Only try to attach "corefile" argument if
208 it starts with a digit.
210 * symfile.c (symbol_reloading): New "set/show" variable.
211 (symbol_file_add): Shorten message about symbol reading.
212 (add_symbol_file_command): Merge with add_syms_addr_command,
213 since this should work on all targets now.
214 (stop_whining): Default to zero, to shut up complaints
215 about bad symbol tables on many systems.
216 (free_named_symtabs): Just exit unless symbol_reloading.
218 * xm-sun3os4.h, xm-sun4os4.h: Define BROKEN_LARGE_ALLOCA,
219 and add comment explaining shared library screw.
221 * source.c: #if defined => #ifdef.
223 Thu Aug 8 12:23:19 1991 John Gilmore (gnu at cygint.cygnus.com)
225 * doc/gdbint.texinfo: Improve doc on porting to new OS's.
227 Tue Aug 6 17:16:15 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
229 * doc/rdl-apps.texinfo: provide default readline-appendix finder
230 (doc/Makefile knows how to make one for local config)
232 * Makefile.in: use doc/Makefile for doc targets
234 * doc/Makefile: GDB documentation now has its own Makefile
235 doc/refcard.tex: renamed from "gdbrc.tex"
236 doc/.Sanitize: add Makefile; recognize renamed refcard.tex
237 doc/gdbint.texinfo: add markup in "Cleanups" chapter
240 Fri Aug 2 00:13:06 1991 John Gilmore (gnu at cygint.cygnus.com)
242 * values.c (baseclass_addr): When reading target memory, use the
243 length of the basetype, not the upper type. We've only malloc'd
244 enough space for the basetype, leading to errors in free().
246 * expprint.c (print_subexp): Print UNOP_MEMVAL of an OP_LONG that
247 ends up as a function specially, since we know the actual type of
248 the pointed-to address. This (somewhat) fixes display of
249 expressions that include misc_function_vector names. Try `cond 1
250 !strcmp("a","b")' then `i b'.
252 * infrun.c: Move DO_DEFERRED_STORES from proceed() to resume().
253 The child can be proceeded from inside wait_for_inferior in
254 evaluating breakpoint conditions, and DO_DEFERRED_STORES was
255 getting skipped in that case.
257 * expprint.c (print_subexp): Use filtered output, since the
258 subroutines we call use it, otherwise the output is horribly
259 mangled, since output of wrappable stuff comes out late.
261 * Makefile.in: Bump VERSION to 3.98.1
263 * infrun.c (child_create_process): Use execlp to find the
264 shell to exec our target program. This requires some fiddling
265 with `environ' since there is no execlpe().
267 Thu Aug 1 15:35:17 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
269 * Makefile.in, doc/gdbrc.tex, doc/rc-* (new files):
270 Minor rearrangement of refcard permits two new make targets--
271 gdbrc.dvi DVI output for refcard, using CM fonts
272 gdbrc.ps PostScript refcard, using PS fonts
274 Wed Jul 31 16:46:21 1991 John Gilmore (gnu at cygint.cygnus.com)
278 * TODO, Projects, WHATS.NEW, README: Update for gdb-3.98.
279 * Makefile.in (gdb-all.texinfo): Avoid touching file if M4 dies.
281 Wed Jul 31 16:35:58 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
283 * doc/gdb.texinfo: last changes for release.
284 Minor typo and formatting fixes; incorporated most fixes remaining from
285 filed mail commenting on earlier drafts.
287 Added warnings: pipes don't work in run command;
288 conditions are converse of assertions;
289 step over fn without debug info goes to next fn;
290 vars may have "wrong" values near fn entrance, exit
292 Added example from Kingston on printing repeated nonadjacent values
294 Added explicit mention that in Emacs gdb mode C-c and C-z are like
295 shell mode for signals
297 Renamed "Stepping and Continuing" to "Continuing and Stepping" so it
298 doesn't sound so much like its parent "Stopping and Continuing"; also
299 moved entries on continue to top of section, so they don't get lost.
301 Improved installation directions in appendix, added manual formatting
304 Tue Jul 30 17:26:39 1991 John Gilmore (gnu at cygint.cygnus.com)
306 * configure.in: Remove xm.h and tm.h even if we aren't linking
307 new ones, so "./configure sun4; ./configure none" does the right
308 thing. Assume that alldeps.mak and depend are already built in
309 srcdir, and avoid running "make" (particularly "make depend",
310 which involves "gcc") from inside configure. Build Makefile
311 directly rather than building Makefile.conf first.
312 * configure: Regenerate with above changes.
313 * Makefile.in: Use $(BISON) to find bison. Roll VERSION
314 to 3.98. Revise gdb.tar.Z procedure to produce a file
315 called gdb-$(VERSION).tar.Z but which unpacks into a
316 directory called "gdb". Move non-source files out of
317 $(SFILES_SUBDIR). Pretty up alldeps.mak with comments.
318 (depend): Don't try to do "gcc expread.y".
319 (expread.o): Update dependencies by hand.
321 Mon Jul 29 15:21:09 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
324 Fixed a variety of small typos that prevented info from formatting
325 cleanly; altered too-long heading for GPL Appendix, as discussed
326 w/RMS; Changed date on cover to July 91.
328 Fri Jul 26 13:20:02 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
331 (1) Applied some fixes due to comments from Larry Breed (easier ones
333 (2) Eliminated use of @footnote---had my doubts about it anyways, and
334 it's broken in latest texinfo
335 (3) Introduced *some* use of [] for optional arguments, where
336 explanation is not simpler by listing cmd w arg and cmd w/out arg
337 separately. Still not using @deffn.
338 (4) Dropped in GPL-2. NOTE: one of GPL-2 or texinfo is broken; a
339 couple of headings are too long. Need patches to texinfo or revision
342 * Partial update to README (which still needs work for this
343 release!): (1) use of configure corrected for new script,
344 (2) "make gdb.dvi" and "make gdb.info" mentioned.
346 Wed Jul 24 06:44:02 1991 John Gilmore (gnu at cygint.cygnus.com)
348 * symtab.c (lookup_symbol): Don't complain right off about
349 no debug symbols; use the misc function vector first.
350 (list_symbols): Use misc function vector to find symbols
351 that don't have debug info, and print them.
352 (find_pc_symtab): Temporarily avoid fatal() when psymtab
353 PC range doesn't match symtab PC range, as it does on the
354 MIPS because our symtab reading isn't perfect.
356 * dbxread.c (dbx_symfile_read): Make warning about
357 "no debug symbols" slightly nicer.
359 * source.c (select_source_symtab): If "main" symbol exists,
360 but decode_line_spec can't find line info, don't just return
361 a zero; try other source symtabs or give an error.
363 * mipsread.c (parse_partial_symbols): Sort the psymtabs by
364 their low addresses first, then rip through fixing high addrs.
366 * ns32k-opcode.h (sfsr): Bugfix from Rune Nerg}rd,
368 (NS32K_SVC_IMMED_OPERANDS): Reverse the #ifndef.
370 Tue Jul 23 18:52:43 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
372 * Minor, mostly mechanical, cleanup of doc subdir for clean
373 makeinfo'ing and TeXing; also ensured gdb-all.texinfo (post-m4)
374 and gdb.info (post- texinfo2 makeinfo) generated for distribution.
376 Sun Jul 21 03:54:52 1991 John Gilmore (gnu at cygint.cygnus.com)
378 Mostly MIPS and general symbol-reading fixups.
380 * doc/gdbint.texinfo: Add documentation on symbol-reading
383 * mipsread.c: Remove kludges around #include "ecoff.h".
384 Remove redefinitions of a_magic, etc, no longer used.
385 (parse_symbol, ): Convert "Internal:" printfs to complain()ts.
386 Fix global overview comments to match symfile.c protocol.
387 (mipscoff_new_init): Eliminate cur_hdr if we have one.
388 (mipscoff_symfile_read): Eliminate unused code. Avoid
389 sorting all the symtabs, when all we have read here is psymtabs.
390 The symtabs are sorted as they are created anyway. Tell
391 condense_misc_bunches whether we're mainline.
392 (psymtab_to_symtab_1): Pass filename when recursing, to make
393 stack trace more informative.
394 (parse_partial_symbols): Assume cur_hdr as argument.
395 (read_mips_symtab): Don't clobber cur_hdr, so it can be freed.
396 Pass cur_hdr implicitly to parse_partial_symbols. Avoid checking
397 the TYPE_NAME of char *, since that's done in symfile.c.
398 (free_numargs, parse_symbol, add_symbol, add_block,
399 shrink_linetable): Declare these fns void.
400 (upgrade_type): Convert tree of if's to switch. Clean up
401 bogus "off == 0" handling with a complaint. Avoid setting
402 field bitpos and bitsize of array with lower and upper bounds.
403 Check specified bitsize of elements against their actual type's
404 bitsize, and complain if different. Complain about unknown
406 (parse_fdr): Don't assume sizeof(char *) == sizeof (struct *).
407 (psymtab_to_symtab_1): Print names of subsidiary files that
408 are being read in. FIXME, we read far too many files. This code
409 is not the problem, the problem is in parse_fdr where the psymtabs
411 (cross_ref): Result should indicate that we used one aux entry
412 normally, or two if we encountered a "next" entry. This used
413 to leave the caller pointing at the wrong aux entry.
414 (add_symbol): If overflowed cur_block, reallocate it larger,
415 chase all pointers to it, and complain(), rather than clobber memory.
416 (shrink_block): Use xrealloc rather than xmalloc-and-copy.
417 (new_field): Only allocate one field initially, not two.
418 Pull ++ out of macro argument. Simplify.
419 (_initialize_mipsread): Avoid initialization of importd
420 global_psymbols and static_psymbols.
422 * symfile.c (psymtab_to_symtab): Depend on XXX_psymtab_to_symtab
423 to properly set pst->symtab; avoid searching for it.
424 (symfile_fns): Improve comments, add a FIXME.
425 * dbxread.c: Update comments to reflect symfile protocol.
426 (read_ofile_symtab, end_symtab): Return the symtab.
427 (psymtab_to_symtab_1): Set pst->symtab.
429 * coffread.c (coff_symfile_read): tell condense_misc_bunches
430 whether we're mainline.
432 * symfile.h (sym_fns): Remove unused sym_discard member.
433 * coffread.c, mipsread.c, dbxread.c: Remove XXX_symfile_discard.
435 * mtrace.c (mtrace): Take effect if mallwatch is set, even if
436 the environment variable is not.
437 * infcmd.c (finish_command): Use filtered printfs.
438 * cplus-dem.c: Add struct tags to a few unnamed structs.
439 * valops.c (value_coerce_array): Improve comments.
440 * valprint.c (type_print_varspec_suffix): Print array size only
441 if greater than zero.
442 * m88k-tdep.c: Shift some lines left by one space, that had
443 apparently been trashed at some point.
444 * TODO: More things to do, a few got done.
446 Thu Jul 18 22:46:05 1991 John Gilmore (gnu at cygint.cygnus.com)
448 * symtab.h (LOC_EXTERNAL): Eliminate in favor of LOC_STATIC.
449 (ldsymoff, ldsymlen, globals_offset, statics_offset): Improve
451 * dbxread.c (read_dbx_symtab): LOC_EXTERNAL -> LOC_STATIC.
452 * expread.y, findvar.c, symmisc.c: Ditto.
453 * printcmd.c (address_info): Update printed forms of LOC_
454 symbols. Elim LOC_EXTERNAL.
455 (print_frame_args): Keep track of param stack offsets before
456 re-looking up to find the local register param is kept in.
458 * mipsread.c: Use <symconst.h> and <sym.h> rather than <syms.h>.
459 Further integration of mipsread into gdb. Eliminate unused
460 routines, duplicate declarations. Handle static symbols in
461 psymtabs as well as external symbols. When reading symtabs,
462 insert symbols into the correct block (global, static, or a local
464 (read_mips_symtab, parse_partial_symbols): Don't pass useless
466 (mipscoff_symfile_read): Don't call select_source_symtab.
467 (parse_symbol): Use SYMBOL_VALUE_ADDRESS where appropriate,
468 rather than SYMBOL_VALUE.
469 (parse_external): Comment clobbering of top_stack.
470 (parse_partial_symbols): Update comments. Allocate and parse
471 static symbols as well as external symbols. FIXME, enum values
472 are not handled in this pass, but should be. Inline new_psymbol.
473 Use SYMBOL_VALUE_ADDRESS.
474 (psymtab_to_symtab_1): Read symbols into global static block
475 by default (until enter some function's local block context).
476 (sort_blocks): Clean up STATIC_BLOCK as well as GLOBAL_BLOCK.
477 (destroy_all_symtabs, new_psymbol): Eliminate, unused.
479 * source.c (select_source_symtab): Select a source symtab
480 from either the symtabs or, failing that, the psymtabs.
481 (list_command): Update error message.
482 (forward_search_command, reverse_search_command): Use getc, not
483 fgetc, for speed. FIXME, add comment about buffers that die if
484 overrun by long line.
486 * values.c (unpack_field_as_long, modify_field): Avoid shifting
487 by an entire word, which is not portable, if we have a 32-bit
488 field. (Code in dbxread.c already turns such bitfields, if
489 aligned, into ordinary ints, but fixing this will help for other
490 symbol formats and for future changes.)
491 * core.c (core_open): Handle ANSI const brain death.
492 * utils.c (vprintf): Fix varargs typo.
494 Sun Jul 14 00:42:53 1991 John Gilmore (gnu at cygint.cygnus.com)
496 * findvar.c (find_var_value): Handle &function better.
497 * TODO: Document work needed on &fn and &array.
498 * printcmd.c (print_address_symbolic): New arg is the prefix
499 to print if a name is printed.
500 (print_address_demangle): Honor "set print address" now.
501 Use new arg above to improve spacing of output.
502 * valprint.c (val_print): When printing function pointers,
503 print symbolic form too.
504 * breakpoint.c (breakpoint_1): Use new print_address_symbolic.
506 Mon Jul 8 19:02:46 1991 John Gilmore (gnu at cygint.cygnus.com)
508 * core.c (memory_error): Reword error msg to mislead less.
510 * mips-pinsn.c (print_insn_arg 'd'): Print $ with reg name.
512 * mipsread.c (read_mips_symtab, read_the_mips_symtab,
513 parse_partial_symbols): Use newer BFD internals (external_filehdr
514 and external_aouthdr), byte-swap the fields that we care about
515 before using them, and make the file header data local to
516 read_the_mips_symtab rather than global.
518 Sat Jul 6 01:34:15 1991 John Gilmore (gnu at cygint.cygnus.com)
520 * ns32k-opcode.h (movmw, movmd): Fix opcodes. Bug fix
521 from Rune Nerg}rd <runene@ifi.uio.no> on 5 Jul 1991.
523 * main.c (command_line_input): Flush stdout and stderr
524 before every call to readline. This reportedly fixes a bug
525 that comes up in Sys V running emacs-gdb and/or xxgdb,
526 when stdin/out are pipes or sockets.
528 Thu Jul 4 14:47:06 1991 John Gilmore (gnu at cygint.cygnus.com)
530 * configure.in, Makefile.in: Avoid rebuilding "depend" as much.
531 Avoid declaring Makefile dependencies, because GNU Make stupidly
532 tries to update it if we do.
534 * coffread.c: Revise for minor changes to bfd internal coff
537 * configure: If -template= is given a relative path, make it
538 absolute before recurring in subdirectories.
540 * configure, configure.in, Makefile.in: Install "configure" script
541 as replacement for config.gdb.
542 * config.gdb, Makefile.dist, Makefile.sdir: Remove
543 * README: Update for configure, mostly. FIXME.
545 * Add dec3100 as equivalent to littlemips. Indicate in all host &
546 target config files that they are for the host. When the lines
547 get copied into the Makefile, this makes it more obvious what's
550 Mon Jun 24 23:49:07 1991 John Gilmore (gnu at cygint.cygnus.com)
552 * sparc-opcode.h (trap opcodes): Avoid leading spaces or
553 tabs, which end up in the disassembler output inadvertently.
555 Wed May 29 23:01:03 1991 John Gilmore (gnu at cygint.cygnus.com)
557 Make it compile cleanly in an ANSI GCC2 environment.
559 * blockframe.c: <stdio.h>
560 * cplus-dem.c: free takes a void *, ifdef __STDC__
561 * dbxread.c (read_huge_number): avoid gcc2 bug hoisting calc of
563 * defs.h (alloca): Avoid doing anything if alloca already def'd.
564 * stddef.h, stdlib.h: Remove these files.
565 * symtab.c: Avoid declaring qsort, close.
566 * symfile.c: Avoid declaring close.
567 * utils.c (vprintf): Declare "ap" arg as proper va_alist.
568 * sparc-tdep.c: Avoid including lots of Sun-host-specific files.
570 Assorted other changes.
571 * dbxread.c: include "libaout.h", not "liba.out.h".
572 * printcmd.c (print_frame_args): Set recurse properly for
573 indentation of struct and array parameters.
574 * valops.c (value_cast): Allow cast to void.
575 * infrun.c (resume): If NO_SINGLE_STEP, call machine dependent
576 single_step() in a target-independent fashion.
577 * sparc-tdep.c (single_step): Don't call ptrace ourselves, just
578 set up to be ready to continue. This makes us target independent.
579 * infptrace.c (child_resume): Remove call to single_step; now
580 can single step a SPARC target of any kind.
582 Wed May 22 18:18:24 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
584 * Makefile.dist, doc/gdb.texinfo, doc/*-m4.texinfo: split up GDB
585 docn into separate sections---basically chapters, plus two loose
586 pieces that can be configured to go in different places. This
587 allows GNU m4 to preprocess the manual without coredumping.
589 * Makefile.dist: tell TeX where to find texinfo.
591 Mon May 20 12:15:04 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
593 * Makefile.dist, doc/gdb.texinfo: respectively create, and use,
594 the new target "rdl-apps.texinfo" which captures the Makefile
595 variable that records where to find the Readline libraries.
597 Sun May 19 05:36:59 1991 John Gilmore (gnu at cygint.cygnus.com)
599 * tahoe-pinsn.c: #include "tahoe-opcode.h", not "opcode.h".
600 * tm-tahoe.h (FIX_CALL_DUMMY): Ignore more parameters.
601 * defs.h (const, volatile): Only define if not already defined.
602 * Makefile.dist (gdb.tar.Z): Create doc subdir w/out CVS/RCS crud.
604 * README: Update for release 3.95.
605 * config.gdb: Don't create readline dir in subdir builds.
606 * main.c: Include with "..." form for non-system include files,
607 so "gcc -MM" for "make depend" works.
608 Include readline files with "...h" rather than <readline/...h>.
609 * mipsread.c: Include "ecoff.h" rather than "intel-coff.h".
611 * coffread.c: Undo minor damage done by Rich Pixley. Use
612 different internal and external representations of COFF
613 data structures. Use new BFD routines for swapping them in and
615 * symfile.c (free_named_symtabs): Avoid freeing file names that
616 are null or empty. Old i960 tools seem to produce files that
617 claim to have empty names, causing each successive file read
618 to blow away the previous one.
619 * sparc-xdep.c (deferred_stores): Repair minor damage by Rich.
620 Move deferred_stores to top of file, but don't separate its
621 #define's from its variable. Add commentary.
622 * Makefile.dist: Fix Rich damage; undo "configure" changes in
623 favor of keeping the (working) config.gdb. Move readline
626 Fri May 17 12:49:56 1991 Per Bothner (via gnu at cygint.cygnus.com)
628 * dbxread.c (read_struct_type): Try to handle g++ version 1 MI
630 * infptrace.c (fetch_registers): no result, since now void.
631 * tconfig/news: target depends on m68k-tdep too.
633 Fri May 17 14:40:14 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
635 * Makefile.dist: added readline/inc-*.texinfo to dependencies for
638 * readline/inc-history.texinfo, readline/inc-readline.texinfo:
639 applied various small fixes due to or inspired by RMS comments
641 * doc/gdb.texinfo: finished using all RMS comments, save those for
642 appendices on readline and cmd history (which are in other source
645 Thu May 16 18:06:05 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
647 * doc/gdb.texinfo: (1) Updated w/ref to RMS comments through
648 chapter 9; (2) documented 'break' command's menu mode for
649 overloaded names, in response to hgs problem report C++ p-31
651 Wed May 15 11:02:48 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
653 * doc/gdb.texinfo: (1) better introductory example; (2) more
654 consistent use of @code, @samp, @file, @kbd throughout; small
655 cleanups to first three nodes; (3) new "Contributors" node;
656 (4) Appendix, Renamed Commands; (5) divert specialized startup
657 instructions to "Targets" chapter for generic manuals, while
658 leaving them up front for manuals specific to specialized
659 environments; (6) apply fixes from RMS comments through chapter 4.
661 * pretex.m4: modify explanatory text slightly (and redefine
662 "regexp") to keep GNU m4 from complaining. (It still crashes
663 later, but one step at a time...)
665 Wed May 15 10:32:12 1991 John Gilmore (gnu at cygint.cygnus.com)
667 * readline/readline.c (update_line): Avoid dereferencing a pointer
668 before comparing it to its bounds. Saber caught this.
669 (init_terminal_io): Don't set BC from the "pc=" termcap variable,
670 and only set PC if tgetstr returned non-null. Saber caught this.
672 Tue May 14 16:29:53 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)
674 * Makefile.dist: put gdb.dvi stuff (updated to use M4 preprocessor
675 stuff for config manual) here where it counts; updated
676 to use new subdir structure (gdb/doc/).
678 * Makefile: generated from above via
682 * gdbint.texinfo: added instructions on generating gdb.info* files
683 locally for release. These are ordinary info
684 files, formatted from gdb.texinfo (via gdb-all.texinfo, see
685 Makefile)---but due to use of texinfo 2, can't count on makeinfo
686 to generate these, so we distribute them already formatted.
688 * gdb.texinfo: included full Info node and menu crud (as generated
689 by C-u M-x texinfo-master-menu using the texinfo-2 elisp code).
691 * Makefile: updated "gdb.dvi" target to use M4 preprocessor;
692 put in comments-for-future gdb.info target (one day makeinfo will
695 Tue May 14 13:51:36 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)
697 * gdb.texinfo: Updated to include new or old undocumented
698 commands, at least the following (perhaps some others I forgot to
699 record): info f, info float, info path, info program, info s, info
700 set, info source, info terminal, info types, info user, set/show
702 Also covered all recent GDB command renames for v4.
704 Mon May 13 14:57:46 1991 John Gilmore (gnu at cygint.cygnus.com)
706 * mipsread.c: Rather than keeping count of how many symtabs
707 and psymtabs we have, for sorting purposes, count them when
708 we need to sort. This fixes bug in rereading of symbol tables.
710 Fri May 10 15:43:33 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)
712 * infcmd.c: renamed "info path" to "show paths"

727 symtab.h, target.c, target.h: Lint.
728 * core.c: setup and select frame after reading shared libs,
729 else reading shared libs will clobber them. Lint.
730 * utils.c (error): Force out any buffered wrap text.
732 Fri May 3 22:01:56 1991 John Gilmore (gnu at cygint.cygnus.com)
734 * remote.c: Remove decls of memory_insert_breakpoint
735 and memory_remove_breakpoint, no longer used. (Suggestion of
738 * Makefile.dist: use ${subdir} in paths of BFD and LIBIBERTY,
739 to make it easier to interface to "configure"'d libraries.
741 Fri May 3 13:10:01 PDT 1991 Roland Pesch (pesch at fowanton.cygnus.com)
743 * valprint.c: introduce "set p", "set pr", "show p" and "show pr" as
744 aliases for set/show print.

1295 * dbxread.c (read_dbx_symtab): Allow N_SOL to cleanly take us back
1296 to the main file, as well as to include files. Also, put global
1297 functions into the global psymtab, to make "i fun" work.
1298 (end_psymtab): Free named symtabs and psymtabs for a file, once a
1299 new psymtab for it has been read.
1300 * coffread.c (end_psymtab): Free named symtabs and psymtabs for
1301 a file, once a new symtab has been read for it.
1302 * mipsread.c: FIXME. We need to do the same for MIPS, but it
1303 looks harder to determine the top-level block before it's been
1304 queued to the psymtab list.
1306 * symfile.c (symbol_file_add): Use filtered printing and wrap it.
1307 If we have wiped out any old symbol tables, clean up at end of

1311 * symtab.h (GLOBAL_BLOCK, STATIC_BLOCK, FIRST_LOCAL_BLOCK): New
1312 defines for the blocks of a blockvector that contain global and

1323 static psymbols list.
1324 (types_info): Restore this function from its untimely #if 0.

1347 (dbx_psymtab_to_symtab): symfile might be zero, cope.
1348 * exec.c (exec_ops): Add_syms_addr is valid in our tvec.
1349 (set_section_command): New command ("section xxx yyy" -- should
1350 be renamed to "set section xxx yyy" FIXME) which sets the
1351 base address of a section of the exec file, overriding the
1352 virtual address that BFD reports.
1354 Fri Apr 5 17:14:39 1991 John Gilmore (gnu at cygint.cygnus.com)
1356 * exec.c: Add add_syms_addr_command to exec_ops, so you can

1361 * tm-i386v.h (FLOAT_INFO): Don't define it, since the code
1362 for printing the float info is host-dependent, not
1363 target-dependent. FIXME.
1364 * i386-pinsn.c: Move #includes to top, remove useless ones.
1365 * i386-tdep.c: Don't bother including <.../reg.h> since we
1366 don't use it (and it doesn't exist on host systems).
1368 * ieee-float.c (ieee_extended_to_double): Convert NaN to Inf.
1369 Convert negative numbers properly.
1370 (ieee_test): Make numbers really random; fix format arg.
1372 * infcmd.c (attach_command, detach_command): Don't repeat on CR.
1373 * core.c (core_detach): Unpush core_ops, which might not be on
1374 top. We used to just pop the top, which broke things. Don't
1375 need dont_repeat() any more.
1376 (core_file_command): Psst! Don't repeat it.
1377 * remote-nindy.c (nindy_detach): Don't need dont_repeat() now.
1378 * expprint.c (print_subexp): Avoid switch fallthru on
1379 BINOP_ASSIGN_MODIFY, so we can print += and such.
1380 * frame.h: Fix typo.
1381 * inflow.c (kill_command): After killing inferior, print our
1382 current frame in the core file, if we have one.
1383 (generic_mourn_inferior): When inferior dies, either select
1384 the current frame (in the new target, e.g. core file), or
1385 set both the current and selected frames to NULL.
1387 Changes from Peter Schauer.
1389 * infptrace.c: Avoid <sys/ptrace.h> on USG.
1391 * Make all file names fit in 14 characters (sigh and damn!):
1392 mv hp300hpux-xdep.c hp300ux-xdep.c
1393 mv symmetry-xdep.c symm-xdep.c
1394 mv symmetry-tdep.c symm-tdep.c
1395 mv convex-opcode.h convx-opcode.h
1396 mv tm-vxworks960.h tm-vx960.h
1397 mv tm-vxworks68.h tm-vx68.h
1398 mv Makefile.srcdir Makefile.sdir
1399 mv gdb-int.texinfo gdbint.texinfo
1400 mv remote-sa.m68k.shar rem-m68k.shar
1401 mv remote-multi.shar rem-multi.shar
1402 * Makefile.dist, README, config.gdb, convex-pinsn.c,
1403 tconfig/symmetry, tconfig/vxworks960, tconfig/vxworks68,
1404 xconfig/hp300hpux, xconfig/symmetry: Change names to shorter
1407 * command.c (user_info_1, user_info): New command for listing
1408 the user-defined commands.
1410 Wed Apr 3 15:00:26 1991 John Gilmore (gnu at cygint.cygnus.com)
1412 * dbxread.c (really_free_pendings): Clear file_symbols
1413 and global_symbols after freeing them; otherwise, running
1414 this function twice (if it appears twice on the cleanup
1415 chain), we try to free things twice.
1417 * dbxread.c (read_dbx_symtab): Calculate end_of_text_addr
1418 based on text_addr (the address of text in core), not on addr (the
1419 offset between text in the .o file and in core). This change
1420 is from Peter Schauer.
1422 * main.c: Define ALL_CLEANUPS as a cast of zero.
1423 (return_to_top_level): Use it.
1424 (main): Do all cleanups after each command run as part
1425 of the gdb startup sequence. Also do all cleanups before
1426 entering the command loop, and every time we exit the command
1427 loop and reenter. Before, the cleanups from the startup sequence
1428 were being left undone until the first error!
1429 (command_loop): Rename do_nothing cleanup to command_loop_marker
1430 so we can see it easily when examining the cleanup chain.
1431 (init_signals): Add another do_nothing for signal handling.
1432 (quit_command): Only try to kill target if it has execution.
1433 Problems in the target stack got us into a state where
1434 inferior_pid was nonzero but none of the targets had execution.
1435 In this state you couldn't exit gdb.
1437 * dbxread.c: Two changes from Peter Schauer.
1438 (echo_command): Fflush output after an echo command.
1439 (show_history): Pass all args to cmd_show_list.
1441 * utils.c (init_malloc): Call mtrace to turn on tracing
1442 if the environment variable MALLOC_TRACE is set to a file name.
1443 * mtrace.c: Add source file which provides a log of every malloc,
1444 free, and realloc to a trace file.
1445 * mtrace.awk: Add source file which analyzes the trace file.
1446 * Makefile.dist (GNU_MALLOC, MALLOCSRC): Add mtrace.{c,o,awk}.
1447 (VERSION): Roll to 3.94.3.
1449 * breakpoint.c (breakpoint_1): Add a space to "i watch" output.
1450 (check_duplicates): Don't bother with watchpoints.
1451 (set_raw_breakpoint): Comment about danger of this routine.
1452 (watch_command): Parse and eval all args before calling
1455 * solib.c (find_solib): Avoid error in referencing memory to
1456 see if any more shared libraries have been added. This is
1457 particularly useful if the target has terminated. Bug reported
1460 Changes from Peter Schauer <pesrem@regent.e-technik.tu-muenchen.de>
1461 in bringing up 3.94.2 on the Sun-3.
1463 * Makefile.dist: Include CFLAGS in rule for cplus-dem.o.
1464 * breakpoint.c (enable_breakpoint): Check for valid watchpoint
1465 expression (in scope) before reenabling watchpoint.
1466 * signame.c (init_sigs): Add missing declaration of i, fix
1467 sys_siglist declaration.
1468 * source.c (list_command): Fixed range computation to use
1470 * stack.c (backtrace_command): Do not allow command if target has
1471 no stack, print informative error message.
1472 * target.c (target_command): Do not write into command line
1473 because this fails if the target command is used in a user defined
1474 command. [This change was enhanced by gnu to support any-
1475 unique-prefix matching on target names.]
1476 * valops.c (value_struct_elt): Avoid infinite loop on an
1477 erroneous attempt to print the member of function (try p main.p).
1479 Mon Apr 1 17:05:45 1991 John Gilmore (gnu at cygint.cygnus.com)
1481 * expread.y (name_no_typename): Avoid reduce/reduce errors
1482 caused by ambiguity in handling NAME_OR_INT and NAME_OR_UINT.
1483 Since the GDB parser really doesn't use name_no_typename in a
1484 name-only context, the parser can't tell the diff between
1485 names and numbers here. Avoid allowing a name_no_typename
1486 to be a NAME_OR_*INT to resolve the conflict.
1488 Sun Mar 31 20:12:07 1991 John Gilmore (gnu at cygint.cygnus.com)
1490 Bugfixes from Mark Fox (markf@wrs.com) (test=testField.c):
1492 * valprint.c (val_print_fields): bitfield printing didn't handle
1493 byte order. Indirect through a few more fns to cope.
1495 * values.c (modify_field): also cope with byte order.
1497 Sat Mar 23 10:02:21 1991 John Gilmore (gnu at cygint.cygnus.com)
1499 Cleanup for release 3.94.2:
1501 * Makefile.dist: Pull REMOTE_OBS. Fix saber includes for BFD
1502 include files. Roll version to 3.94.2.
1504 * coffread.c (init_stringtab): Read length into unsigned char
1505 array before swapping; don't assume 32-bit longs.
1507 * target.c (target_info): Don't bother with get_sym_file, just use
1508 the symfile global variable.
1509 * symtab.h, symfile.c (get_sym_file): Delete it.
1511 * dbxread.c (dbx_symfile_init): Don't depend on long == 4 bytes.
1512 (define_symbol): Set symbol line number to 0 if not gcc-compiled.
1513 (read_type): Replace one more error() with complain().
1515 * mipsread.c (parse_partial_symbols): Replace printf with complain.
1517 * i960-tdep.c: Fix copyright attribution.
1519 * config.gdb: Quote all backquotes in doublequotes. You can
1520 quote me on that. BSD 4.4 shell found this one.
1522 * infptrace.c (throughout): The third argument to ptrace is an
1525 * infrun.c (wait_for_inferior): When program has terminated, we
1526 have to call target_terminal_ours before we pop that target off
1527 the stack (e.g. before a call to target_kill or
1528 target_mourn_inferior). This fixes problem where a program
1529 terminates, then GDB stops for (tty output) and you have to type
1530 "fg" to the shell to resume it. FIXME: This code for what to
1531 do after termination really should be in normal_stop instead.
1533 * gdbcore.h (read_memory_check): Change declaration; it changed
1536 * terminal.h: Include <sgtty.h> before <sys/ioctl.h>, since in BSD
1537 4.4 prereleases, this avoids a bug in their sgtty compatability
1539 * remote.c: Use terminal.h rather than hand-rolling the same.
1541 * signame.c, signame.h (psignal): Arg is unsigned, not int.
1542 * utils.c (strsave, strstr): Fix arg types.
1543 * valprint.c (val_print): lint
1545 MIPS symbol table support from Per Bothner:
1547 * symfile.c (symtab_fns): Remove initializer table that needs to
1548 be hacked for each new symbol file format supported.
1549 (add_symtab_fns): New function, chains symbol table
1550 handlers into the global list.
1551 (symfile_init): Search this list.
1552 * symfile.h: Add next pointer, declare add_symtab_fns.
1553 * coffread.c (_initialize_coffread): Call add_symtab_fns.
1554 * dbxread.c (_initialize_dbxread): Call add_symtab_fns.
1556 * mipsread.c (psymtab_to_symtab_1): return void instead of (struct
1557 symbol *). Thus, we no longer need the hack to trash
1558 pst->filename. Good, since that hack confused code in symfile.c!
1560 (reorder_symtabs, destroy_all_symtabs): Removed static
1561 all_symtabs, which was used to qsort symtabs in reorder_symtabs.
1562 Instead, the latter now uses a temporary array (stack-allocated
1563 from an obstack, and then freed).
1565 (parse_symbol): Added a hack to fix up BLOCK_{START,END} if they
1566 haven't been set in the outermost stBlock of a procedure. This was
1567 a problem with f77 binaries on Ultrix 4.?.
1569 (new_symtab, new_symbol, new_type): Continue changing code to use
1570 obstacks more and otherwise conform to dbxread internal style.
1571 Made the free_code of symtabs be free_linetable (as in dbxread)
1572 instead of free_contents. This implies memory leaks when reading
1573 a new symbol table, until the conversion is finished. Did change
1574 (struct symbol) and (struct type) to be allocated on the
1575 symbol_obstack. Blocks and blockvectors are among the things
1578 * mipsread.c (parse_partial_symbols, parse_fdr): It hasn't been
1579 tested much, but it solved one problem (reported by Meissner), and
1580 cleans up some other things. The problem happened when an
1581 included file contains actual code (functions) and not just
1582 definitions. The mips coff is a little inconvenient there, since
1583 it may cause a procedure to be mapped to the wrong psymtab.
1585 * mips-tdep.c (heuristic_proc_desc): Minor cleanup.
1586 * mips-xdep.c (fetch_core_registers): Minor cleanup. FIXME,
1587 this will need work for the new core paradigm.
1589 Opcode patches from the net:
1591 * mips-opcode.h: fix incorrect disassembly of the mfc1, cfc1, and
1592 ctc1 instructions. Also, the cvt.d.w and cvt.s.w instructions were
1593 missing altogether - they are added here. From Bruce Bauman.
1594 * mips-opcode.h: The low mask for C0 instructions was too small.
1595 From Garrett Lau. I modified the fix to check the entire 32-bit
1598 * ns32k-opcode.h: Fix opcodes for deiw and deid. From Bruce
1601 Thu Mar 21 12:56:46 1991 John Gilmore (gnu at cygint.cygnus.com)
1603 Roll in changes from Per Bothner (Tue, 25 Sep 90 11:11:04):
1605 * dbxread.c (read_type): Pointer subtraction (value_sub in
1606 valarith.c) sometimes failed because the types of the
1607 pointers being subtracted were not identical.
1608 These differed because dbxread.c was allocating pointer types
1609 using dbx_alloc_type+smash_to_pointer_type instead of
1610 lookup_pointer_type. I failed to find a justification for the
1611 former, so I changed it to use the latter. Similarly, I
1612 replaced smash_to_function_type by lookup_function_type,
1613 and smash_to_reference_type by lookup_reference_type.
1615 * mipsread.c (parse_symbol, upgrade_type, parse_procedure,
1616 _initialize_mipsread): corresponding changes.
1618 * symtab.c (smash_to_{pointer,reference,function}_type): eliminate.
1620 * source.c (mod_path): Do tilde_expand on each component of the path,
1621 rather than on the (list of) paths as a whole.
1622 (print_source_lines): Set first_line_listed in addition to
1623 current_source_symtab and current_source_line. If the source was
1624 not findable, after a "dir" command to fix the problem,
1625 a "list" would get the wrong lines.
1627 While I was there... (gnu):
1629 * dbxread.c (read_type): Change error to complaint.
1631 Thu Mar 21 12:56:46 1991 John Gilmore (gnu at cygint.cygnus.com)
1633 First attempt at detailed understanding of symbol table memory alloc.
1635 * dbxread.c (dbx_symfile_read): Free our string table if we
1636 aren't the mainline. Free the "info" struct since we're done with
1638 (init_psymbol_list): Free any previously allocated psymbol lists.
1639 (): FIXME: Should realloc-down the psymbol lists when done reading
1640 the main symbol file?
1642 * symmisc.c (free_symtab): Free fullname field too.
1644 * xm-hp300hpux.h (USG): #undef then #define so Makefile can -D.
1645 (REGISTER_ADDR): Make result type unsigned int.
1647 * xconfig/{i386*,hp300hpux,altosgas,altos}: All config files that
1648 define REGEX must also define REGEX1 (its dependency).
1650 Tue Mar 19 21:28:57 1991 John Gilmore (gnu at cygint.cygnus.com)
1652 * tconfig/i960: No longer works, points you at vxworks960 or
1655 * xgdb.c, XGDB-README: Remove file. Users can get the much
1657 * Makefile.dist: Remove all trace of xgdb.
1659 * breakpoint.c (breakpoint_1): Pass demangle arg to
1660 print_address_symbolic.
1661 (clear_breakpoints): Remove unused function.
1662 (breakpoint_re_set_one): Guts of breakpoint_re_set.
1663 (breakpoint_re_set): Use catch_errors to do them all anyway.
1665 * gdb-int.texinfo (Host versus Target): Add section on what is
1666 a "host" feature versus what is a "target" feature.
1668 * infcmd.c (path_command, path_info): Handle the PATH variable
1669 (object search path) as conveniently as the source search path.
1670 * environ.c (set_in_environ): Set some vars in GDB's environment,
1671 in addition to the child's. PATH, G960BASE, G960BIN for starters.
1672 * source.c (mod_path): New function, from guts of
1673 directory_command, modifies a path. Used by path_command.
1674 (directory_command): Call it.
1675 * defs.h (strsave): Declare.
1677 * utils.c (sevenbit_strings): Add new printing option.
1678 (printchar): Use it.
1679 (strsave): Provide this handy helper routine.
1680 (set_width_command): Rename set_screen_width_command.
1681 (_initialize_utils): "set screen-width" => "set width";
1682 "set screen-height" => "set height"; add sevenbit-strings.
1684 * infcmd.c (do_registers_info): Print floating point registers
1685 in raw hex as well as float format, regardless of whether it is
1686 a "virtual" convertible register.
1687 * tm-sparc.h (PRINT_REGISTER_HOOK): Print every pair of float
1688 regs as a double, just in case it's being used that way.
1689 * values.c (unpack_long): Comment on array/function coercion.
1690 (unpack_double): Argument is in target byte order now. For
1691 integer arguments, just call unpack_long and float the result.
1692 * m68k-tdep.c: include defs.h for "const" handling.
1693 * remote-nindy.c: Use ieee-float stuff.
1694 (nindy_fetch_registers): Unpack double regs to host double, then
1696 (nindy_store_registers): Pack extendeds to host double, flip
1697 around by misusing unpack_double, send as target double.
1699 * tm-vxworks68.h (FRAME_CHAIN): Handle current frame pointer of
1700 zero, as when stopped at the first instruction of a process.
1702 * blockframe.c: Fix filename in comment (param.h => tm.h).
1703 * sparc-tdep.c (skip_prologue): More explicit nudging comments.
1704 * tm-68k.h: Fix typos.
1706 Fri Mar 15 01:09:34 1991 John Gilmore (gnu at cygint.cygnus.com)
1708 Changes from a bringup on the DEC Vax under Ultrix 4.0.
1710 * coredep.c (fetch_core_registers): Pass end-address of register
1711 section to register_addr as expected. Don't call supply_register
1712 if we'd just pass it garbage.
1714 * dbxread.c (read_dbx_symtab): Skip N_NSYMS on Ultrix.
1716 * exec.c (xfer_memory): Use boolean xfer_fn result, not int.
1718 * target.c (push_target, target_info): Cast enums to int for < or
1721 * stack.c (print_frame_info): Identify source file & line
1722 even if we can't print it.
1724 * xm-vax.h (MISSING_VPRINTF): No longer missing in Ultrix V4.0.
1726 Sat Mar 9 10:08:20 1991 John Gilmore (gnu at cygint.cygnus.com)
1728 Clean up IEEE floating point support.
1730 * ieee-float.h: New file.
1731 * ieee-float.c: Write real routines to convert between host
1732 doubles and various target IEEE extendeds.
1733 * m68k-xdep.c: Eliminate assembler code for extended floats.
1734 * xconfig/{3b1,altos,altosgas,hp300bsd,isi,news,news1000,sun2os3,
1735 sun2os4,sun3,sun3os3,sun3os4}: Eliminate use of m68k-xdep.o.
1736 * tm-i960.h, tm-68k.h (REGISTER_CONVERT_TO_VIRTUAL,
1737 REGISTER_CONVERT_TO_RAW): Use ieee_extended_to_double and
1738 double_to_ieee_extended.
1739 * i960-tdep.c: Define ext_format_i960.
1740 * m68k-tdep.c: Define ext_format_68881.
1741 * sparc-tdep.c: Define ext_format_sparc, though unused.
1742 * Makefile.dist (HFILES): Add ieee-float.h.
1743 * inftarg.c: #include "ieee-float.h" for the REGISTER_CONVERT
1746 Obsolete the "coffstrip" program in favor of using BFD's strip.
1748 * nindy-share/coffstrip.c: Remove file.
1749 * nindy-share/nindy.c (coffstrip): Routine to run bfd_strip.
1750 * Makefile.dist: Remove references to nindy-share/coffstrip.c.
1751 * tconfig/nindy960: Remove reference to coffstrip.o.
1753 * Makefile.dist: Roll version number to 3.94.1 (not yet final).
1755 Wed Mar 6 09:56:45 1991 John Gilmore (gnu at cygint.cygnus.com)
1757 * symfile.h: Add symfile_bfd, common between dbxread and coffread.
1758 * dbxread.c: Remove static symfile_bfd.
1759 * infcmd.c (do_registers_info): Add PRINT_REGISTER_HOOK, though
1761 * inftarg.c (child_detach): Pop the child_ops vector if the
1762 detach is successful.
1763 * remote-nindy.c (nindy_create_inferior): Don't push a new
1764 nindy_ops since nindy uses the same one for execution and memory
1766 * core.c (core_ops): Use child_attach and child_create_inferior
1767 rather than default attach and create_inferior functions.
1769 Handle floating point registers in core files.
1771 * sparc-xdep.c (fetch_core_registers): Rewrite for float support.
1772 * sun3-xdep.c (fetch_core_registers): Rewrite for float support.
1773 This version untested since BFD doesn't yet support sun3 core
1775 * hp300hpux-xdep.c: Rewrite fetch_core_registers to new calling
1776 conventions. Fix comments and style. This version has not
1777 been compiled yet, since we have no HP inhouse.
1778 * core.c (get_core_registers): Look for two sections, ".reg"
1779 and ".reg2", and pass both to fetch_core_registers sequentially.
1781 Revise directory path yet again.
1783 * source.c (forget_cached_source_info): Not static any more.
1784 (init_source_path): New default source path is "$cdir:$cwd".
1785 (dir_command): Handle variable arguments ($cdir, $cwd).
1786 (source_info): Print "Compilation directory" rather than
1787 "Originally compiled in" to remind people of $cdir.
1788 (openp): If the path contains $cwd, use current directory.
1789 (open_source_file): If compilation directory is known, replace
1790 first $cdir in path with the compilation directory.
1791 (print_source_lines): Even if we can't print the lines, set the
1792 current symtab and line for future commands like "info source" or
1793 "breakpoint". Also, error message now contains the file name,
1794 line number, and file access error message.
1795 (_initialize_source): Fix help text to describe changes.
1796 * main.c (cd_command): Forget cached source info when we chdir.
1797 * utils.c (strstr): Add simple implementation.
1799 Tue Mar 5 01:41:40 1991 John Gilmore (gnu at fowanton.cygnus.com)
1801 * coffread.c (read_one_sym, init_linetable, init_stringtab):
1802 Byte-swap COFF symbol tables if necessary when reading them in.
1803 Use complain() to replace error message in one spot. Needs
1804 corresponding change in bfd/coff-code.h to make some symbol
1805 swapping routines non-static.
1807 Mon Mar 4 00:53:40 1991 John Gilmore (gnu at cygint.cygnus.com)
1809 Merge changes from Eirik Fuller, for UTek.
1811 * defs.h (errno): Add declaration.
1812 * altos-xdep.c, arm-xdep.c, convex-xdep.c, gould-xdep.c,
1813 hp300hpux-xdep.c, infrun.c, inflow.c, infptrace.c, i386-tdep.c,
1814 i386-xdep.c, pyr-xdep.c, mips-xdep.c, remote-eb.c, remote-nindy.c,
1815 remote-vx.c, source.c, standalone.c, stuff.c, sun386-xdep.c,
1816 symmetry-tdep.c, symmetry-xdep.c, umax-xdep.c, utils.c: Eliminate
1817 declarations of errno.
1819 * remote-eb.c: Define B19200 and B38400 as EXTA and EXTB.
1821 * remote-vx.c: Include <sys/time.h> for UTek; Sun gets it via
1822 <rpc/rpc.h> and <rpc/types.h>.
1824 Sat Mar 2 15:47:55 1991 John Gilmore (gnu at cygint.cygnus.com)
1826 * i960-tdep.c (examine_prologue): Add new argument limit,
1827 which stops the scan at the end of the prologue, or at the PC.
1828 This fixes a problem where it walks down into the code for the
1829 user's statements if that code looks like function prologues.
1830 Mark Fox and I have been bouncing this code back and forth, making
1831 small changes to it. Callers changed to match.
1833 Tue Feb 26 01:47:07 1991 Cygnus John Gilmore (cygnus at yuba)
1835 Cleanup for gdb-3.94 release final:
1837 * Makefile.dist: Remove remote-vx.c, remote-nindy.c, and all
1838 the .c files from vx-share and nindy-share, from the various
1839 macros, since they are not found via ALLDEPFILES.
1840 (SFILES): Add tm-i960.h.
1841 (alldeps.mak rule): Break out ALLDEPFILES_MAINDIR and
1842 ALLDEPFILES_SUBDIR. List all the nindy and vxworks subdir files
1844 (TAGFILES_MAINDIR): Change ALLDEPFILES to ALLDEPFILES_MAINDIR.
1845 (gdb.tar.Z): Use ALLDEPFILES_SUBDIR as well as SFILES_SUBDIR.
1847 Mon Feb 25 16:02:35 1991 Cygnus John Gilmore (cygnus at oldman)
1849 * am29k-tdep.c: Add contribution line.
1850 (examine_prologue): Cache information about function prologues in
1851 the misc-function-vector to avoid lots of references over the
1852 serial line while examining instructions.
1854 * core.c (core_close): New function made from cleanup_core.
1856 * core.c, exec.c, inftarg.c, remote-eb.c, remote-nindy.c,
1857 remote-vx.c, remote.c, target.c, target.h,
1858 Update target_ops vector to add attach, close, and load entries.
1859 Use add_syms_addr_command, not add_file_addr_command, for
1860 add_file. Break out close routine from existing code.
1862 * dbxread.c (really_free_pendings): Don't free pending_blocks;
1863 they are in an obstack.
1864 (read_dbx_symtab): Relocate end_of_text_addr in the psymtab.
1866 (define_symbol): Add symbol type parameter; change callers;
1867 pass type parameter to DBX_PARM_SYMBOL_CLASS macro to allow
1868 it to influence the symbol class on the i960.
1869 (define_symbol): Swap LOC_CONST's into target byte order.
1871 * exec.c (exec_close): New function.
1872 (exec_file_command): Call it.
1874 * findvar.c (read_relative_register_raw_bytes): Doc byte order,
1875 Fix byte order of frame pointer.
1876 (read_var_value): Result of 0 if var's value can't be found,
1877 e.g. missing FRAME_ARGS_ADDRESS. Byte-swap LOC_CONST and
1878 LOC_LABEL values to target order. Add LOC_LOCAL_ARG.
1879 (locate_var_value): Use read_var_value and use its lazy address
1880 as the location of the var's value. Lint.
1882 * i960-pinsn.c (next_insn): Add routine from vxgdb for scanning
1885 * i960-tdep.c (arg_address, i960_frame_find_saved_regs): Remove
1886 obsolete Intel versions in favor of vxgdb versions.
1887 (check_host, byteswap, byteswap_val, reorder_val): Eliminate
1888 code dealing with byte order of values, which Intel did in host byte
1889 order rather than gdb-4's target byte order.
1890 (i960_frame_chain_valid): Move to nindy-tdep.c.
1891 (examine_prologue, skip_prologue, frame_find_saved_regs,
1892 frame_args_address, leafproc_return, saved_pc_after_call,
1893 pop_frame): Add vxgdb versions from Mark Fox.
1894 (examine_prologue, frame_struct_result_address): Add code
1895 to deal with the saved value of G13 (struct return address
1897 (frame_args_address): Modify Mark's version to prefer the
1898 saved value over the current value in the topmost frame.
1899 Cache result in the frame info to avoid performance hair in
1901 (print_fault): Add gdb960 code for printing faults.
1902 (_initialize_i960): Actually call check_host.
1904 * ieee-float.c (ieee_extended_to_double, ieee_double_to_extended):
1905 add stub routines. FIXME, these currently just return zero!
1907 * infcmd.c (program_info): Use PRINT_RANDOM_SIGNAL.
1908 (attach_command): Call target_attach, not target_open, now.
1910 * infrun.c (normal_stop): Make global, not static, for vx_attach.
1911 (child_attach): Rename from child_open.
1912 (wait_for_inferior): Use PRINT_RANDOM_SIGNAL. If stop_pc is zero,
1913 don't confuse it with a zero step_resume_break_address.
1915 * inftarg.c (child_detach): Eliminate inferior_pid test.
1916 (child_files_info): Clean up message a bit.
1917 (child_ops): Use child_attach, not child_open, to attach.
1919 * mem-break.c: #ifdef out the whole file if BREAKPOINT is not
1920 set (e.g. on VxWorks or NINDY). Move read_memory_nobpt from
1921 findvar.c to here, since it depends on the contents of the
1922 shadow_contents of breakpoints, but keep if #if 0 since it is
1925 * nindy-tdep.c: New file, contains nindy_frame_chain_valid, moved
1928 * printcmd.c (address_info): Handle LOC_LOCAL_ARG. Lint.
1929 (ptype_command, display_command): Eliminate have_inferior_p and
1930 have_core_file_p in favor of target_has_stack or
1931 target_has_execution.
1932 (print_frame_args): Handle LOC_LOCAL_ARG. Eliminate duplicate
1933 code for actually finding the values of arguments, though we still
1934 keep track of the maximum stack offset for use in printing unnamed
1935 arguments. Handle missing FRAME_ARGS_ADDRESS.
1937 * remote-nindy.c (i960_print_fault): Move to i960-tdep.c.
1938 (struct nindy_regs): Define registers passed to/from nindy.
1939 (nindy_fetch_registers, nindy_store-registers): Translate between
1940 nindy and GDB formats for the registers.
1941 (dcache_init): Statically allocate the cache, since it was being
1942 allocated by a malloc that was never freed anyway.
1943 (nindy_create_inferior): Error, not core dump, if no exec file.
1944 (nindy_before_main_loop): Use target_load, not target_add_file.
1946 * remote-vx.c (net_load): Specify large timeout for load
1947 requests. Allow user to break out with INTERRUPT.
1948 (net_break): Remove useless code, clean up. Change callers.
1949 (parse-args, skip_white_space, find_white_space): Clean up arg
1950 parsing to cope with quoted strings.
1951 (net_wait, net_quit): Never call error, just return status.
1952 (vx_read_register, vx_write_register): Cleanup status checking.
1953 #ifdef the code based on which CPU we are using (960 or 68k),
1954 FIXME, this should be completely general but it isn't yet.
1955 (vx_xfer_memory, vx_resume): Cleanup status checking.
1956 (vx_run_files_info): Improve message.
1957 (vx_load_command): Renamed from vx_add_file_command. Allow load
1959 (net_ptrace): Remove unused routine.
1960 (vx_wait): Adopt code from vxgdb960 to cope with broken
1961 connections to target machine and prompt to disconnect. Remove
1962 debug printouts. Map some EVENT_'s to SIGnals.
1963 (add_symbol_stub, vx_open): Print names of object files we found,
1964 and "ok" if we read their symbols OK. Clarify output in general.
1965 (vx_attach, vx_detach, vx_kill): Add these commands.
1966 (vx_convert_from_virtual, vx_convert_to_virtual): Simplify.
1967 (vx_run_ops): Turn off all_mem, to avoid spurious msg in the
1968 "info files" output, and create_inferior, since we already have
1971 * stack.c (frame_info): Replace Frame_unknown with 0.
1972 (print_frame_arg_vars): Handle LOC_LOCAL_ARG.
1973 (return_command): Pop until the PC matches as well as the FP,
1974 so it works even if the FP is shared with another function,
1975 as in "frameless" or "leaf" procedures.
1977 * symfile.c (load_command): renamed from add_file_target_command.
1978 (add_syms_addr_command): renamed from add_file_addr_command.
1979 (add_syms_command): Stub to call target_add_syms.
1980 (_initialize_symfile): Change command names and descriptions,
1981 add-file => add-syms, and load from alias to its own command.
1983 * target.c (kill_or_be_killed, maybe_kill_then_attach,
1984 maybe_kill_then_create_inferior): Default for attempts to start
1985 a process, if one is already running, is to ask about killing
1986 it and retry if yes.
1987 (upstack_create_inferior): #if-0 it, strata obsolete it.
1988 (push_target, unpush_target, pop_target): to_close() a target
1989 before unstacking it.
1990 (target_info): Renamed from target_files_info.
1991 (_initialize_targets): Rename "i files" as "i target", accessible
1994 * target.h: Improve comments about the target_ vectored routines.
1996 * tm-i960.h: Remove NINDY-specific stuff to tm-nindy960.h.
1997 Convert commenting style to standard GNU style.
1998 (DBX_PARM_SYMBOL_CLASS): allow LOC_LOCAL_ARG's to be recognized.
1999 (SKIP_PROLOGUE): No longer a no-op.
2000 (SAVED_PC_AFTER_CALL): Now handles leaf procedures.
2001 (*_REGNUM): Sort register numbers.
2002 (REGISTER_BYTES, REGISTER_BYTE, REGISTER_RAW_SIZE,
2003 MAX_REGISTER_RAW_SIZE, REGISTER_CONVERTIBLE,
2004 REGISTER_CONVERT_TO_VIRTUAL, REGISTER_CONVERT_TO_RAW): Float regs
2005 are now 10 byte extendeds, not 8 byte doubles.
2006 (FRAME_CHAIN_VALID): Make this config-dependent, since it differs
2007 for nindy versus vxworks targets. FIXME, this should possibly go
2008 in the target vector.
2009 (EXTRA_FRAME_INFO, INIT_EXTRA_FRAME_INFO): Cache both
2010 frame_saved_regs and arg pointer with each frame.
2011 (FRAMELESS_FUNCTION_INVOCATION): New leafproc support.
2012 (FRAME_ARGS_ADDRESS): Use cached result.
2013 (FRAME_ARGS_ADDRESS_CORRECT): New, avoids g14 guessing.
2014 (FRAME_FIND_SAVED_REGS): Change arg to subsidiary fn.
2015 (PRINT_RAMDON_SIGNAL): Call print_fault.
2016 (POP_FRAME): Now works.
2018 * tm-nindy960.h: Break this off tm-i960.h. NINDY-specific
2019 option parsing and startup; STACK_END_ADDR, FRAME_CHAIN_VALID,
2020 BREAKPOINT, and DECR_PC_AFTER_BREAK are here.
2021 (ADDITIONAL_OPTION_HANDLER): use target_load, not
2024 * tm-vxworks960.h: Break this off tm-i960.h. VxGDB specific
2025 startup; DECR_PC_AFTER_BREAK, and FRAME_CHAIN_VALID are here.
2027 * valarith.c (value_subscripted_rvalue): Avoid handling
2028 floats and doubles specially; it gave alignment errors. Lint.
2030 * valops.c (value_of_variable, value_of_this): Error if unknown
2033 * valprint.c (print_floating): Bcopy rather than pointer-deref,
2034 to avoid alignment problems.
2035 (value_print): Handle unknown value address.
2036 (cplus_val_print): Two args are ignored; remove them. Change caller.
2037 (val_print): Use unpack_long rather than pointer-deref.
2040 (unpack_long, unpack_double): Use bcopy rather than pointer-deref
2041 to avoid alignment problems.
2042 (value_being_returned): Error if return value unknown.
2043 (set_return_value): Add bogosity warning, FIXME. *
2045 * TODO: A woman's work is never done.
2047 * Makefile.dist: Distribute REMOTE_OBS into tconfig files.
2048 Separate INCLUDE_CFLAGS for use with lint. Add LINTFILES.
2049 Add ieee-float.o to OBS.
2050 * tconfig/{nindy960,vxworks68,vxworks960}: Include the desired
2051 REMOTE_OBS remote-interface files in the TDEPFILES and TM_FILE.
2052 * tconfig/i960: FIXME. Half-merge, produce warning if config'd.
2054 Changes to generalize the VxWorks RPC protocol slightly, to handle
2055 i960 as well as 68000.
2057 * vx-share/dbgRpcLib.h (VX_SOURCE_STEP): Add.
2058 * vx-share/reg.h: Produce i960 regs #ifdef I80960
2059 * vx-share/xdr_ptrace.c: Skip FPA registers if 960.
2060 * vx-share/xdr_rdb.h: Add SOURCE_STEP struct and xdr decl.
2061 * vx-share/xdr_rdb.c: Add xdr_SOURCE_STEP routine.
2062 * vx-share/xdr_regs.c: Add xdr_regs, xdr_fp_status, xdr_ext_fp
2063 for i960. Change xdr_vectors to xdr_opaques for 68k registers,
2064 so they will move in target byte order rather than network
2065 byte order (happens to be the same).
2067 Mon Feb 25 03:41:44 1991 John Gilmore (gnu at cygint.cygnus.com)
2069 * tm-convex.h (END_OF_TEXT_DEFAULT): Remove #if 0'd block.
2071 Sun Feb 24 00:55:53 1991 John Gilmore (gnu at cygint.cygnus.com)
2074 Add contribution lines to various files, showing where they
2077 * breakpoint.c (break_insn, check_break_insn_size,
2078 read_memory_nobpt): Remove to mem-break.c.
2080 * xm-*.h, param-no-tm.h, tm-29k.h, valprint.c: Change BYTE_ORDER to
2083 * tm-29k.h (STAB_REG_TO_REGNUM): Warn user if symbol table
2084 entry has bad register number. This change is not
2085 tested in this release, FIXME.
2087 * frame.h: Eliminate Frame_unknown in favor of a simple zero.
2090 * value.h: Force value's contents field to be aligned to hold
2091 at least a double or a long long (if supported). This avoids
2092 doing bcopy's in and out of the contents field.
2094 (step_1): Avoid coredump under obscure circumstances when we
2097 * symtab.h (misc_info): Add field to misc function vector for
2098 any kind of cached information the target code desires. AMD
2099 29000 uses this to avoid repeating examine_function_prologue's.
2101 * coffread.c: Lint. Remove static symfile, read_section_header.
2102 core.c (have_core_file_p): Lint: remove.
2103 expprint.c (print_subexp): Lint.
2104 infptrace.c, valops.c, valprint.c: lint.
2106 Roll in changes from vxgdb-5.0.1:
2108 * symtab.h: Comment byte order of each address class. Add
2109 LOC_LOCAL_ARG for frame-relative args (960).
2110 expread.y: Use LOC_LOCAL_ARG where LOC_ARG is used.
2111 symtab.c, symmisc.c: ditto.
2113 * infrun.c (init_wait_for_inferior): Clear stop_signal.
2115 * remote.c (remote_resume): Error if resume with a signal.
2117 * symfile.c (prim_record_misc_function): Clear misc_info.
2118 (fill_in_vptr_fieldno): Check stub type of arg.
2120 * valops.c (value_cast): Avoid looking up names of types whose
2121 name we don't know, to prevent coredump. Sun CC produces typedef
2122 rtx and the name of *rtx is zero...
2124 Mon Feb 18 21:16:25 1991 John Gilmore (gnu at cygint.cygnus.com)
2126 Roll in changes from final AMD 29000 port (Tiemann).
2128 tconfig/am29k: Add COFF_ENCAPSULATE and TARGET=TARGET_AM29K
2129 for ../include/a.out.encap.h. This might not work now that BFD
2130 is separately compiled. Instead, BFD support for encap will have
2131 to translate machine type 29k into the right COFF_MAGIC.
2133 * infcmd.c: Remove references to inferior_pid that aren't used
2134 in actual ptrace calls; use target_has_execution, etc.
2135 (have_inferior_p): Remove function.
2136 (program_info): Print target info rather than "process number";
2137 avoid gratuitous messages unless from_tty.
2138 (run_stack_dummy, finish_command): Set proceed_to_finish.
2139 infrun.c: Remove inferior_pid refs. Decl & init proceed_to_finish.
2140 main.c: Lint. Lose have_inferior_p().
2141 inferior.h (have_inferior_p): Remove, lint.
2142 (proceed_to_finish): Add flag to ask that all regs be saved
2143 by normal_stop, for the few commands that need it, speeding up
2144 serial I/O. Add comments to stop_registers.
2146 * remote-eb.c: Remove newline from breakpoint message we grep
2147 for. Never time out when running the user program.
2151 Wed Feb 13 15:34:40 1991 John Gilmore (gnu at cygint.cygnus.com)
2153 Roll in changes from vxgdb-5.0.1:
2155 * dbxread.c (read_dbx_symtab): If we encounter a "FORTRAN COMMON"
2156 symbol in its raw form, we are processing an unlinked ".o" file.
2157 See if the target environment has assigned it an address, using
2158 target_lookup_symbol (VxWorks does), and enter it into the symtab
2161 * tm-vxworks.h (FRAME_CHAIN, FRAME_CHAIN_VALID): Override usual
2162 68k versions for a simpler version that assumes zero FP at bottom.
2163 Fixes bug of truncated stack reports.
2165 * target.h (target_lookup_symbol): Define this routine's args
2166 and result, finally.
2168 * target.c (nosymbol): Default routine for target_lookup_symbol.
2169 (target_default): Default lookup_symbol and call_function too.
2170 (files_info): Only print has_all_memory warning if a non-dummy
2173 * remote-vx.c (vx_read_register, vx_convert_to_virtual,
2174 vx_convert_from_virtual): If target does not have floating point,
2175 zero register "values", and avoid doing cross-net conversions.
2176 (vx_lookup_symbol): Rename net_lookup_symbol, add to vectors.
2177 (vx_open): Rearrange code that attaches to target and reads
2178 symbols for all loaded modules, to work if some of the modules
2179 are not accessible. Add symbol_stub() and add_symbol_stub()
2180 as callbacks from catch_errors(). Allow connect attempt to be
2181 interrupted painlessly with ^C (FIXME, there are still some bugs
2182 if the interrupt happens during symbol reading.). Print
2183 final message with puts_filtered, since symbol messages are
2188 * main.c (catch_errors): Only print errstring if non-null.
2189 (command_loop): Avoid an ioctl per command to test ISATTY.
2191 * remote-vx.c (net_load): make static; avoid sophomoric msg.
2192 (vx_xfer_memory): Return correct result!
2193 (vx_files_info): Indicate whether target has float or not.
2194 (vx_lookup_symbol): Complain, not error, if target gone.
2195 (vx_open): Print "Connected" msg before disabling immediate-quit.
2196 [FIXME: lookup_symbol and vx_open changes need testing.]
2198 target.c, remote-eb.c, inftarg.c, am29k-opcode.h, target.h,
2199 tm-29k.h, tmm-vxworks68.h, symfile.c, gdb-int.texinfo: Add
2200 contributor lines and update copyrights to 1991.
2202 Changes from an attempted H-PUX host port:
2204 * infptrace.c (PT_ATTACH, PT_DETACH): Handle HP/UX, which
2205 defines PT_ATTACH and PT_DETACH but not PT_KILL.
2206 * remote-eb.c (eb_open): Misplaced endif kills sysv H/PUX.
2207 * remote-vx.c: include <sys/time.h> for HPUX.
2208 * hp300hpux-xdep.c (fetch_core_registers): Rewrite old
2209 "core_file_command" routine to BFD regime. May not work yet.
2211 Attempted port of "gdb-3.4 Van Jacobson xgdb" to modern gdb.
2213 * xgdb.c: Replace X10 version with some VJ version.
2214 (FIXME: Its copyright assignment is not on record.)
2215 * xgdb.c: Update include files to X11R4 (Xaw crud).
2216 (xgdb_display_source, create_text_widget): fix call to
2217 get_filename_and_charpos. Rewack source window stuff for X11R4
2218 (gleaned from include files, and "nm's" of binary libraries, since
2219 I had no doc available).
2220 (append_selection, append_selection_word): Disable with FIXME
2221 since R4 changed interface here.
2222 (create_buttons): Add back the old set of buttons.
2223 (xgdb_create_window): Fix call to XtInitialize (&argc not argc).
2225 * Makefile.dist (xgdb, xgdb-init.c): Update for X11R4 on Suns.
2226 Roll VERSION to 3.94 (not yet final though).
2228 Sat Feb 9 09:46:25 1991 John Gilmore (gnu at cygint.cygnus.com)
2230 * obstack.h (obstack_ptr_grow, obstack_ptr_grow_fast,
2231 obstack_int_grow, obstack_int_grow_fast): Eliminate
2232 cast on left of assignment, which gives MIPS cc fits and is
2235 * sparc-pinsn.c (print_insn): Eliminate 'set' test, subsumed by
2236 F_ALIAS. Use printf, not fprintf, when not passing a file
2238 (compare_opcodes): Check that identical instructions have
2239 identical opcodes, complain otherwise.
2241 * sparc-opcode.h (st %fsr): Fix opcode "lose" mask. This
2242 was reported by Roland McGrath.
2243 (unimp): Only match if exactly zero instruction. (Roland)
2244 (branches and traps): Generate all variations of these
2245 instructions with macros, based on a single call that defines
2246 each condition name and its binary representation.
2247 (set): Turn on alias bit, to avoid test in sparc-pinsn.c.
2249 * valprint.c (val_print_fields): Take, and use, format parameter.
2250 This means that "p/x struct" again prints the elements in the
2251 desired format. Changed callers.
2253 * stack.c (frame_info): Use filtered output, and indicate wrap
2254 points. Remove kludgy formatting designed to avoid line wrap.
2256 * utils.c (wrap_here): If the line is already full (because
2257 we had printed a long indent or long wrapped string), do an
2258 immediate newline-and-indent.
2260 * m68k-pinsn.c (print_insn_arg): Bugfix from
2261 ntmtv!thompson@ames.arc.nasa.gov (Mike Thompson): 'bkpt #0'
2262 instruction is incorrectly disassembled as bkpt #8.
2264 * dbxread.c (end_psymtab): Bugfix from Peter Schauer
2265 <pesrem@regent.e-technik.tu-muenchen.de>: If you want to set a
2266 breakpoint in a *.y file gdb will say Reading in symbols for *.y...
2267 and then will dump core (sometimes). I traced it back to an
2268 uninitialized symfile_name in psymtab_to_symtab.
2269 (const_vol_complaint): Add quotes to message.
2270 (define_symbol): Only believe line number if gcc_compiled.
2271 Avoid allocating symbol if we will not return it.
2273 Add target strata support so that newly established targets go
2274 into their right place in the target stack (e.g. a new exec file
2275 doesn't wipe out the ability to access the running process).
2277 * target.h, core.c, exec.c, inftarg.c, remote-eb.c,
2278 remote-nindy.c, remote-vx.c, remote.c, target.c: Add to_stratum
2279 and initialize it properly in all the targets.
2281 * target.h: Document strata. Change return type of push_target.
2283 * target.c (nomemory): new function for dummy memory access.
2284 (tcomplain): Rename complain, now also used in symfile.c.
2285 (push_target): Push targets within strata. New return value shows
2286 whether new target is on top of stack or not. Always keep dummy
2288 (target_files_info): Ignore dummy target.
2290 * core.c (core_open): Warn user, and skip accessing file, if the
2291 core target is not the topmost target in the stack.
2292 * remote-nindy.c (nindy_create_inferior): Avoid unpush_target, now
2295 * remote-vx.c: Remove vx_prepare_to_store from vxworks memory
2296 target_ops, it doesn't belong there since we have no regs there.
2297 Change name of target from machine => memory to clarify.
2299 Thu Feb 7 16:32:09 1991 John Gilmore (gnu at spiff.cygnus.com)
2301 * Freeze version 3.93 for release.
2303 * Makefile.dist: Handle vx-share and nindy-share subdirs
2304 properly when building gdb.tar.Z.
2306 * symtab.c: lint; add no_symtab_msg to consolidate the messages
2307 printed in various places, so I could change just one copy.
2309 * dbxread.c, coffread.c: Change references to bfd->iostream
2310 to cast to FILE *, now that BFD avoids needing types defined
2311 in other header files.
2313 Tue Feb 5 21:39:35 1991 John Gilmore (gnu at cygint.cygnus.com)
2315 * command.c, dbxread.c, expprint.c, infcmd.c, infptrace.c,
2316 infrun.c, printcmd.c, remote-nindy.c, source.c, sparc-tdep.c,
2317 sparc-xdep.c, symfile.h, symmisc.c, utils.c, valprint.c: Lint
2318 (actually gcc -Wall).
2320 * dbxread.c: Remove first_global_sym, last_global_sym, since
2321 they are never referenced.
2323 * defs.h (baud_rate): Declare.
2324 main.c: Define it, and add the -b option to set it.
2326 * gdb-int.texinfo: Add text on how to define a new host or target
2327 architecture, prompted by Per Bothner's questions about MIPS
2330 * gdb.texinfo: Document "complaints". Change doc of -q since
2331 gdb no longer prints the copyright and blurb if you specify a file
2332 name to be debugged (just like Emacs). Add doc for Nindy-specific
2333 command line flags for specifying target serial port and such.
2334 Update copyright to 1991.
2336 * gdbcore.h: Remove a large mass of now-useless crud, since BFD
2337 has taken over for us the job of ripping up executable files. The
2338 crud caused Per Bothner's port to not compile.
2340 * infrun.c (normal_stop): Avoid printing "Program exited
2341 normally" if we are in batch mode. This allows a GDB which
2342 executes a program on a target system, to behave like a Unix
2343 command (input from stdin, output to stdout, no extraneous
2346 * main.c (main): Allow additional machine-dependent command line
2347 options to be specified with the ADDITIONAL_OPTIONS,
2348 ADDITIONAL_OPTION_CASES, ADDITIONAL_OPTION_HELP, and
2349 ADDITIONAL_OPTION_HANDLER macros. Also allow machine-dependent
2350 processing to occur just before the main loop with
2351 BEFORE_MAIN_LOOP_HOOK.
2352 (main): If a "core file" argument is specified, and it is not a
2353 core file, try it as a process ID to attach.
2354 (symbol_completion_function): Attempt to cope with
2355 "show screen-" TAB, not very successfully. This needs more work,
2357 (batch_file): New function, returns whether we are reading
2358 commands from an interactive tty on stdin, or from somewhere else.
2359 Called by normal_stop since it doesn't get from_tty passed down
2360 to it like many commands do.
2362 * remote-nindy.c: Handle command line options for nindy
2364 (nindy_before_main_loop): Prompt user for tty name if they
2365 don't specify it before getting to the interactive command loop.
2367 * tm-i960.c: Add ADDITIONAL_OPTIONS, etc, to handle -O, -brk,
2368 and -r command line options. Also add hook before main loop
2369 to make it easy to specify a tty.
2371 * TODO: More things to do, one done.
2373 Mon Feb 4 23:57:39 1991 John Gilmore and Mike Tiemann (at cygint.cygnus.com)
2375 * dbxread.c: Make complaint() calls pass pointer, not struct.
2376 Add complaints about badly formatted C++ type information
2377 (const/volatile indicator, and parse errors resulting in
2378 error_type). Fix C++ virtual member fn comment.
2379 (read_struct_type): Avoid bumping pointer if we got a parse
2380 error; this prevents our walking beyond the end of a string.
2381 Terminate loop on null char as well as semicolon.
2382 (process_one_symbol): Fix the LBRAC fix so that it uses the
2383 last previous SLINE, FUN, or SO record's PC address. C++ debug
2384 symbols did not have SLINE records in a useful order compared
2385 to the LBRAC records.
2386 (define_symbol): Handle "catch" records.
2388 * symtab.c (check_stub_type): Added new complain
2389 `stub_noname_complain' and added a consistency check to
2390 keep the debugger from crashing when finishing from an
2391 exception frame. A real fix will be needed later.
2393 Sat Feb 2 10:43:05 1991 John Gilmore (gnu at cygint.cygnus.com)
2395 * infcmd.c (attach_command): Make global.
2397 * Makefile.dist (REMOTE_OBS): Make these compile by default,
2398 but make them easy to comment out. Perhaps later they should
2399 be enabled by what CPU you configure for? FIXME.
2400 (VERSION): Roll to 3.93.
2401 (pinsn.o): Remove rule for obsolete file.
2402 (dbxread.o,coffread.o,mipsread.o): Use ${srcdir} explicitly.
2404 Run down a problem that manifested by printing the wrong function
2405 name in stack traces of read_ofile_symtab. Turned out that the
2406 problem was the SunOS 4.1.1 (and previous) C compiler outputs
2407 the LBRAC symbol with an address in the *data* segment, which
2408 blew our binary search through the blocks.
2410 * dbxread.c: Use the complain() facility consistently to bitch
2411 about problems in the symbol file we are reading.
2412 (finish_block): Add code to check the nesting of the blocks;
2413 complain and Procrust them to fit if wrong.
2414 (make_blockvector): Check the order of the blocks, complain
2415 [but don't cope] if wrong.
2416 (process_one_symbol): ifndef SUN_FIXED_LBRAC_BUG, check LBRAC
2417 symbols to be sure their PC value is greater than the last SLINE
2418 (line number) symbol we've seen, complaining and adopting the
2419 SLINE PC value if wrong.
2421 * symfile.h (struct complaint, complaint_root, complain,
2422 clear_complaints): Add.
2423 * symfile.c (complain, complaint_root, clear_complaints): Add
2424 facility to deal with non-fatal complaints and to regularize their
2426 (symbol_file_add): Clear complaint counters to allow new complaints.
2427 (initialize_symfile): Add 'set complaints' and 'show complaints'.
2429 * dbxread.c (dbx_symfile_read): Remember the address and size
2430 of the string table for the main symbol file, so we won't read it
2432 (dbx_psymtab_to_symtab): Fix the check for main symbol file,
2433 to avoid reading the string table yet again. Lint.
2434 (throughout): Improve filtered output, including word wrap.
2435 (read_range_type): Improve Bothner's fix to handle other types too.
2437 * utils.c: Improve line wrap implementation. Handle unlimited
2438 width by making chars_per_line unsigned.
2439 (puts_filtered): New, easy, function.
2441 * defs.h (puts_filtered): add.
2443 * mipsread.c (compare_symbols, sort_symtab): Remove these fns,
2444 call the identical sort_symtab_syms() in symfile.c instead.
2446 * expread.y: Suggest the `file' command rather than `symbol-file'.
2448 * command.h (enum var_types): Add zinteger for seroable
2450 * command.c (do_setshow_command): Handle var_zinteger. Restructure
2451 nested if's into a switch.
2453 * breakpoint.c (bpstat_print): If bpstat "print" flag is not set,
2454 we did not stop because of a breakpoint (it must have been for
2455 some other reason, like a "stepi"), so don't print anything.
2457 * symtab.c: Include <sys/types.h> all the time. Now that BFD
2458 doesn't include <sys/types.h>, old SunOS's require it for
2461 Sat Feb 2 10:39:15 1991 Per Bothner (bothner@cs.wisc.edu)
2463 A test port of gdb-3.92.6 to the Sony NEWS.
2466 Don't normally link in remote- or vx stuff.
2467 Some of it doesn't compile, and it wastes space for 99% of the users.
2468 Remove reference to no-longer-used HAVE_VPRINTF.
2469 Fixed BFD_DEP typo to BFD_DIR.
2471 Fix cast in arg to bfd_h_getlong.
2472 Make char *prefix be const.
2473 Fix how certain range types are mapped into builtin unsigned int types.
2475 Remove 2 #includes. They cause errors (on Sony, at least),
2476 and aren't needed (they wern't in earlier versions).
2478 print_address_symbolic should never demangle labels
2479 (since it prints *assembler-level* labels).
2481 [This was superseded by the change to printcmd below.]
2484 Add some "volatile" return types to avoid warnings.
2485 If MISSING_VPRINTF add vprintf function and not just macro
2486 (since vprintf is used in printcmd.c).
2488 Unless __GNUC__, use obstack_grow instead of obstack_ptr_grow.
2489 (The latter isn't grokked by some PCC-based compilers.)
2491 [This change is in abeyance, we prefer to fix obstack_ptr_grow.]
2493 Make chunk size of dont_print_obstack 32*4 instead of default 4096.
2494 * nindy-share/coffstrip.c
2495 Added some forward declarations (otherwise, gcc complains
2496 about implicit extern redefined as static).
2498 Sun Jan 20 02:38:19 1991 John Gilmore (gnu at cygint.cygnus.com)
2500 Changes inspired by Per Bothner:
2501 * printcmd.c (print_address_symbolic): Take additional parameter
2502 specifying whether to demangle.
2503 (print_address): Pass in asm_demangle to control demangling.
2504 (print_address_demangle): New fn, takes explicit arg to control
2506 * utils.c: Add new vars demangle and asm_demangle, and let them
2508 (fputs_demangled): If !demangle, just print the argument.
2509 (fprint_symbol): If !demangle, just print raw symbol.
2510 * valprint.c (val_print): Call print_address_demangle rather than
2511 print_address, to cause demangling to depend on the global
2512 rather than assembler-level demangling setting.
2513 * WHATS.NEW, gdb.texinfo: Document.
2515 * main.c (show_command): Show all settings if no arg.
2516 (initialize_main): Make "info set" the same as naked "show".
2517 * command.c (cmd_show_list): Handle prefix commands in the
2518 list, and print the name of the setting as well as its English
2519 description and value.
2521 Allow gdb functions to specify where a line should wrap if it
2522 exceeds the size of a terminal line. Use it to make the output
2524 * utils.c (set_screen_width_command): New fn, mallocs a buffer
2525 of the right size when screen width changes.
2526 (set_screensize_command, screensize_info): Remove #if 0'd fns.
2527 (wrap_here): New fn, indicates a point in the output where we
2528 should wrap the line rather than just letting it overflow at a
2530 (fputs_filtered): Implement wrapping.
2531 (n_spaces): New fn, returns a pointer to N spaces.
2532 (print_spaces_filtered): Use n_spaces.
2533 * defs.h (n_spaces): Declare.
2534 * stack.c (print_frame_info): Wrap with 4-space indent after
2535 fn name and before filename and line number.
2536 * printcmd.c (print_frame_args): Wrap with 4-space indent
2537 before each argument name is printed.
2538 * valprint.c (value_print): Wrap with no indentation before
2540 (val_print_fields): Wrap with indentation relative to nesting
2541 level before each field name.
2542 (val_print): Wrap with nesting indentation before array elements.
2543 * command.c (do_setshow_command): Avoid extra newlines,
2544 wrap with 4-space indent around values printed, end with period.
2545 * WHATS.NEW, gdb.texinfo, gdb-int.texinfo: Document.
2547 * breakpoint.c (breakpoint_1): Implement addressprint for
2548 "info breakpoints" display. Change file name and line number
2549 format to " at file:nnn" rather than " (file line nnn)".
2550 * gdb.texinfo: Document.
2553 Fri Jan 18 07:21:25 1991 John Gilmore (gnu at cygint.cygnus.com)
2555 Frozen for gdb-3.92.6 release.
2557 README, WHATS.NEW: Update for 3.92.6 release.
2559 tconfig/{altos, i386v, i386v32, m88k, umax}: Eliminate
2560 coffread.o from configs since it is now built by default.
2561 tconfig/{3b1, altosgas, arm, convex, hp300bsd, hp300hpux,
2562 i386v-g, i386v32-g, isi, merlin, news, news1000, np1, pn,
2563 pyramid, symmetry, vax, vxworks68}: Eliminate dbxread.o
2564 from configs since it is now built by default.
2566 Makefile.dist: Update for release 3.92.6. Handle files that
2567 have been moved to ../include, ../getopt, or ../bfd. Add
2568 saber.suppress and tests directory. Add config.status to
2569 the release (it will say "none").
2571 coredep.c: Minor formatting fixes.
2573 These changes were made in early December but only checked in now:
2574 * nindy-share/Onindy.c, nindy-share/coffstrip.c,
2575 nindy-share/nindy.c: lint
2576 * nindy-share/nindy.c (ninStopWhy): Don't byteswap the
2577 register values coming back from the target; we store values
2578 in target byte order everywhere.
2580 Wed Jan 16 19:01:37 1991 John Gilmore (gnu at cygint.cygnus.com)
2582 * am29k-opcode.h, am29k-pinsn.c: Add 29050 opcodes.
2584 * valprint.c (cplus_val_print, val_print_fields): New functions,
2585 which print C++ objects. They conspire to avoid printing a
2586 virtual base class more than once, following all the twists and
2587 turns of C++ virtual base rules.
2588 (val_print): Call the above rather than do it by hand.
2590 * symfile.c (symbol_file_add): Only reset symfile_mtime for main
2591 symbol file, not for added files like shared libs. This really
2592 needs to be generalized to a timestamp per file.
2594 * core.c (cleanup_core): Avoid coredump if no core file.
2596 * config.gdb: Accept -host or -target in place of +host or
2599 * coffread.c (find_linenos): Avoid desupported BFD interface
2600 to line numbers. We still read them manually rather than using
2601 BFD's "generic" features.
2603 * gdbrc.tex, threecol.tex: Add GDB reference card and its
2605 Makefile.dist: Add refcard to OTHERS list for creating tar files.
2607 * Makefile.dist: Eliminate use of $< in explicit targets.
2609 * readline/Makefile: Use $< rather than $*.c, which does not
2610 include the VPATH in GNU Make.
2612 * tconfig/i960-bout, tconfig/i960-coff: These are identical
2613 copies of tconfig/i960, added for global configuration
2614 compatability. All i960 versions can read both coff and b.out.
2616 * tm-88k.h: Fix multiline macro that lacked \'s. Remove
2617 COFF_FORMAT and COFF_CHECK_X_ZEROES since these are now handled
2620 * TODO: Think of more things to do.
2622 Wed Jan 2 19:09:29 1991 John Gilmore (gnu at spiff.cygnus.com)
2624 tconfig/{am29k,i960,sun2*,sun3*,sun4*}: Eliminate config
2625 of sdb versus dbx debug symbols. Add kludge for 68881 80-bit to
2626 64-bit float conversion.
2628 tconfig/sun4, tconfig/sun3, xconfig/sun4, xconfig/sun3: Make
2629 equivalent to sun?os4 so global config works.
2631 Wed Jan 2 18:20:51 1991 John Gilmore (gnu at spiff.cygnus.com)
2633 Fix from Eberhard Mattes <mattes@azu.informatik.uni-stuttgart.de>
2635 * main.c: Only declare linesize once; declare pagesize not at
2636 all, since it is never used.
2637 (main): Clear newly allocated line before it is used.
2639 Fri Dec 28 00:13:42 1990 John Gilmore (gnu at cygint)
2641 Further stabilization for the Intel 960.
2643 * Makefile.dist: Parameterize the location of the "include"
2644 and "bfd" directories, as well as "getopt". Add symfile.c.
2645 Link in both dbxread and coffread. Fix up "make depend" to
2646 rewack the locations of include, bfd, and getopt in its output.
2648 * README: Document moving include files, improve some of
2651 * coffread.c: Move common code out to symfile.c. Change
2652 symbol_file_command style interface to use new *_symfile_init
2653 and *_symfile_read interface under BFD. Use BFD internal
2654 info to locate line table, symbols, etc.
2656 * core.c (core_fetch_registers): Rename to get_core_registers
2657 to avoid confusion with fetch_core_registers.
2658 (register_addr): Move to coredep.c, which is already machine
2659 dependent. This leaves core.c pretty clean of dependencies.
2661 * coredep.c (register_addr): Accept this routine from core.c.
2663 * dbxread.c: Move common code (with coffread.c, etc) into new
2664 symfile.c. Each psymtab now contains a pointer to the
2665 format-dependent function that knows how to read it in. Make
2667 (dbx_psymtab_to_symtab): Renamed from psymtab_to_symtab_2.
2668 (process_one_symbol): Add code to complain about a "compiler bug
2669 we muzzle here", if we actually see it.
2671 * eval.c (evaluate_subexp): Insert missing "break" statements
2672 in code that determines whether a variable is an lvalue in
2673 memory, register, or whatever. I detected this via a compiler
2674 bug in which it *almost* mashed out the whole switch statement.
2676 * gdb-int.texinfo: Add minor sections on configuring gdb for
2677 release, and about the README file.
2679 * infcmd.c (registers_info): Fix formatting somewhat. Still
2680 not as pretty as before, but it handles byte swapping.
2682 * remote-nindy.c: If data cache routines are interrupted while
2683 waiting for the remote end, be sure that any uninitialized cache
2684 blocks are on the free list, not on the valid list!
2686 * symfile.h: Flesh out this header file with all the various
2687 routines and variables that have been merged in from dbxread.c
2688 coffread.c, and symtab.c to symfile.c.
2690 * symfile.c: New file, containing code common to dbxread.c,
2691 coffread.c, and some code from symtab.c. All generic code for
2692 reading symbol files should be in here now.
2693 (unrecord_misc_function): Remove unused function.
2695 * symtab.h: Remove file-reading things to symfile.h.
2697 * symtab.c: Remove file-reading things to symfile.c.
2699 * tm-i960.h: Fix FRAME_CHAIN types; define PRINT_RANDOM_SIGNAL
2700 to decode i960 fault types.
2702 * target.h, remote.c, remote-eb.c, remote-vx.c, remote-nindy.c,
2703 target.c: Change type of the "resume" function from int to void,
2704 since its result was never used.
2706 Sat Dec 22 02:51:40 1990 John Gilmore (gnu at cygint)
2708 * main.c: Replace "stupid" with "caution"; you now "set caution
2711 * printcmd.c (print_scalar_formatted): Fix typo in 'g' format
2713 * infcmd.c (do_registers_info): Call val_print to deal with the
2714 byte order of the registers being printed. FIXME, this makes
2715 the formatting of the output uglier.
2717 * infcmd.c (wait_for_inferior): If PRINT_RANDOM_SIGNAL is
2718 defined, call it for signals the debugger doesn't itself use.
2719 The i960 uses this for more detailed fault information.
2721 * remote.c (remote_open): If arg is null, print help rather than
2724 * sparc-xdep.c (register_valid): Avoid declaring size, since
2725 various modules will think of various sizes depending on the
2726 architecture of their tm-file. FIXME, we need protection against
2727 actually entering one of those modules, which would clobber
2728 storage if not for the target architecture compiled into gdb.
2730 * stack.c (up_command, down_command): Always print the frame
2732 (up_silently_command, down_silently_command): New commands
2735 * i960-pinsn.c (reg), i960-tdep.c: Lint.
2737 * i960-tdep.c (i960_frame_chain_valid): Lookup_symbol now takes
2738 more parameters than it used to.
2740 * findvar.c (registers): Increase slop to 256 bytes, which should
2741 protect us against even most RISC machines with large register
2743 (locate_var_value): Move declaration inside related ifdef.
2745 * remote-nindy.c (): Use TIOCSETN rather than TIOCSETP
2746 throughout, to avoid throwing away buffered input from the board.
2747 (nindy_wait): Supply_register takes addr_of_value, not value.
2748 (i960_print_fault): Renamed from i80960_fault.
2749 (nindy_fetch_registers): Avoid have_regs stuff, just get them.
2750 (nindy_store_registers): Avoid regs_changed stuff, just stuff
2752 (nindy_create_inferior): Don't bother to write PC_REGNUM since
2753 we can set the PC in the call to proceed(). Unpush nindy_ops
2754 before pushing it on top, to avoid message to user. Eliminate
2755 commentary from Unix machines that just misleads here.
2756 (reset_command): Fix error message to suggest target command.
2758 Wed Dec 19 11:03:56 1990 John Gilmore (gnu at cygint)
2760 Release 3.92.5 as frozen.
2762 Stabilize the merged release...with help from lint, Saber C,
2765 Everywhere: Add include files needed to declare return types
2766 of functions called.
2768 * gdb.texinfo: Roland Pesch is documenting gdb, glory be!
2770 * breakpoint.h: Add undeclared breakpoint functions, and some
2771 functions for display handling since I couldn't think of a better
2774 * breakpoint.c (insert_breakpoints): Make code for disabling
2775 shared library bkpts more likely to work. It's used when we
2776 rerun a program and stop before the shared library has been
2778 (breakpoint_cond_eval, bpstat_stop_status): Pass arg as int,
2779 cast from pointer, so it squeezes through catch_errors.
2780 (bpstat_stop_status): Fix logic broken some time ago. We now
2781 always create a bpstat if the stop address matches a breakpoint,
2782 even if we don't stop there -- just like the old code used to do
2783 before I got my fingers into it (sigh).
2784 (breakpoint_1): Print "ignore count" after "stop only if"
2785 condition, since that's how it actually works.
2786 (mention): Handle watchpoints as well as breakpoints.
2787 (watch_command): use set_raw_breakpoint and mention to do most
2788 of the work (and initialize all the fields!). Only pass one
2789 arg to parse_c_expression, since that's all it takes.
2791 * command.c (not_just_help_class_command): Rename arg to args
2792 since we ignore "unused argument" warnings on vars named "args".
2793 inflow.c (child_terminal_info): ditto.
2794 infptrace.c (kill_inferior): ditto
2795 main.c (catch_errors, version_info, quit_command, pwd_command,
2796 source_command, dump_me_command, editing_info,
2797 set_history_size_command, set_history, show_history,
2799 stack.c (locals_info): ditto
2800 target.c (target_files_info): ditto
2801 valprint.c (set_input_radix, set_output_radix): ditto
2803 * core.c: Remove old variables for handling core and exec file
2804 sections (data_start, data_end, stack_start, stack_end,
2805 reg_stack_start, reg_stack_end, reg_stack_offset, text_start,
2806 text_end, exec_data_start, exec_data_end, text_offset,
2807 exec_data_offset, data_offset, stack_offset). They're
2808 superseded the more general build_section_table and
2810 (get_exec_file): Mention the `file' command.
2811 (read_memory_check): Rename to memory_error, and only call it
2812 in the case of an actual error.
2813 (read_memory, write_memory): call memory_error.
2814 (core_fetch_registers): Register section name is ".reg".
2816 coredep.c: Remove a bunch of crud now that all this file does
2817 is pull the registers out of a core file.
2818 (fetch_core_registers): Rewrite to actually work, I hope.
2820 dbxread.c: Use a.out.gnu.h, not system a.out, now.
2821 Replace index() with strchr(). Remove all the pre-BFD macro
2822 definitions for accessing the symbol file.
2823 (struct dbx_symfile_info): Encapsulate the information that
2824 dbx_symfile_init needs to pass to dbx_symfile_read in this
2827 (dbx_new_init, dbx_symfile_init, dbx_symfile_read,
2828 dbx_symfile_discard): Rearrange symbol file reading to divide
2829 the format-specific part from the format-independent part,
2830 leaving the format-independent part such as file name expansion
2831 and opening in symtab.c. This replaces
2832 partial_symbol_file_open and partial_symbol_file_read.
2833 Symbol_file_read, add_file, add_file_target_command,
2834 add_file_addr_command move to symtab.c. Pass an explicit
2835 "mainline" flag for when reading the main symbol table, rather
2836 than relying on the offset address to be zero or nonzero.
2838 (dbx_symfile_read): Don't allow void *'s to be printed as
2840 (SWAP_SYMBOL): Use bfd routines to byte-swap the symbols.
2841 (ADD_PSYMBOL_TO_LIST): Make the "function call rather than
2842 macro" debug version really work.
2843 (read_dbx_symtab): Remove unref'd parameter inclink.
2844 Avoid swapping N_SLINE symbols, for speed.
2845 Merge N_TEXT!N_EXT case with the other external symbol
2846 definitions' case. Add comments.
2847 (start_psymtab): Allocate the symfile name in the psymtab on
2848 the psymbol_obstack, rather than using the caller's storage.
2849 (end_psymtab): Only allocate a dependencies list if there are
2851 (psymtab_to_symtab_2): Use BFD when reopening file to read
2852 its symbols for real.
2853 (read_struct_type): Add FIXME comments where it needs work
2855 (read_huge_number): Add FIXME about overflows.
2856 (read_range_type): Add FIXME about comparing a long to 1<<32.
2858 * coffread.c: Minor changes to move things closer to the new
2859 regime with symtab.c and dbxread.c Major work is still needed
2862 * exec.c (exec_file_command): Remove old variables (see core.c
2864 (xfer_memory): If memory transfer is right at the end of a
2865 section, don't lose.
2867 * findvar.c (get_saved_register): If value is in a real
2868 register, LVAL is lval_register, not lval_memory.
2870 frame.h: Declare print_sel_frame and record_selected_frame.
2872 gdb-int.texinfo: New file, for GDB internals documentation.
2873 Very simple, unformatted doc of cleanups is there for now.
2875 gdbcore.h: Remove obsolete variables that described a.out
2876 section addresses and offsets. (See core.c above.)
2877 Declare fetch_core_registers and registers_fetched.
2879 getopt.c: Declare char *alloca(); even on SPARC.
2881 infcmd.c (run_command): Call target_kill rather than
2883 (step_command, next_command, stepi_command, nexti_command):
2884 Declare from_tty parameter even though we don't use it.
2885 (run_stack_dummy): argument BUFFER is a char array, not
2886 a pointer to REGISTER_TYPE.
2887 (finish_command): using_struct_return needed a value *,
2888 not a struct symbol *.
2890 * infptrace.c (child_xfer_memory): To avoid dependency on
2891 where sections are in memory, try PT_WRITE_D and if that fails,
2892 try PT_WRITE_I. Most Unixes don't care which you use.
2894 * infrun.c (step_resume_break_shadow): Change to array to
2895 match other breakpoint shadow storage.
2896 (clear_proceed_status): Pass address of bpstat to
2897 bpstat_clear, not the bpstat itself.
2898 (child_create_inferior): FIXME comment about if the child
2900 (start_inferior): Remove old function.
2901 (child_open): Use target_kill rather than kill_inferior.
2902 (wait_for_inferior): Ditto.
2903 (insert_step_breakpoint, remote_step_breakpoint): Use
2904 new step_resume_break_shadow.
2906 * inftarg.c (child_wait): If all child processes die,
2907 pretend that the one being waited for exited with signal 42.
2909 * main.c (command_line_input): When scanning for comments,
2910 don't coredump on unclosed quotes.
2911 (quit_command): Use target_kill rther than kill_inferior.
2912 (_initialize_main): Rename class_user from "user" to
2915 * printcmd.c (print_command_1): Initialize "fmt" if no format
2916 is specified by the user.
2917 (print_frame_args): Only add to args_printed if we are
2918 actually fetching args from the stack (avoiding undefined
2920 (_initialize_printcmd): Remove bogus \{ from string.
2922 * remote-eb.c (eb_open): Avoid coredump on no argument.
2924 * remote-nindy.c: Bring out of Intel environment into new
2925 target environment. Remove all conditional compilation on
2926 I80960. Massive hacking throughout.
2927 (nindy_xfer_inferior_memory): New routine stolen from
2929 (nindy_create_inferior): New routine pieced together, probably
2930 not quite working yet.
2931 (nindy_ops): New target_ops struct for nindy.
2933 * remote-vx.c: Use write_memory rather than target_write_memory
2934 to get error checking.
2935 (vx_add_file_command, vx_open): Use symbol_file_add rather than
2937 (vx_create_inferior): Use target_terminal_ours...
2939 * signame.c (_initialize_signame): Always initialize, since
2940 we need the table for things other than psignal.
2942 * solib.c (solib_add): Use symbol_file_add, not add_file.
2943 (solib_address): Return boolean result rather than struct
2944 pointer which nobody else knows the type of.
2946 * sparc-tdep.c, valops.c: Use write_memory rather than
2947 target_write_memory, to get error checking.
2949 * stack.c (locals_info, catch_info, args_info,
2950 get_selected_block, frame_command, up_command): Use
2951 target_has_stack, rather than have_inferior_p or
2954 * sun3-xdep.c (fetch_core_registers): Rewrite for new BFD regime.
2956 * symfile.h: New file, defining the interface between the
2957 generic and object-file-specific symbol reading code.
2959 * symtab.c: Move generic symbol-reading interface to symtab.c,
2960 from dbxread.c, coffread.c, mipsread.c, etc. Add symtab_fns
2961 table to map BFD targets to symbol-reading modules in GDB.
2962 Change index to strchr.
2963 (lookup_struct_elt_type): Use error() rather than hand-made
2964 simulations thereof.
2965 (lookup_partial_symbol): Speedup slightly when length == 0.
2966 (symbol_file_add): New function.
2967 (symbol_file_command): Call it.
2968 (symfile_open, symfile_init): New function.
2969 (add_file_target_command, add_file_addr_command): moved from
2972 * target.c (target_command): use target_kill.
2974 * target.h (target_files_info): Don't declare, never called
2977 * tm-sun2.h, tm-sun3.h (STACK_END_ADDR): Use system include
2978 files to determine stack end address.
2980 * valarith.c (value_x_binop, value_x_unop): Change error message
2981 to be more useful. Pass proper argument to value_struct_elt.
2983 * valops.c (value_assign): FIXME comment that long long
2984 bitfields will break here.
2986 * Makefile.dist: Add symfile.h, remote-nindy.c, remote-eb.c.
2987 Update `make saber_gdb' to work better.
2989 * TODO: A woman's work is never done.
2991 * cplus-dem.c, environ.c, inferior.h, infrun.c, inftarg.c,
2992 main.c, obstack.c, printcmd.c, remote-eb.c, remote-nindy.c,
2993 remote-vx.c, remote.c, solib.c, source.c, sparc-pinsn.c,
2994 sparc-tdep.c, sparc-xdep.c, symmisc.c, symtab.c, symtab.h
2995 target.c, terminal.h, tm-sparc.h, tm-sunos.h, utils.c,
2996 valops.c, valprint.c, exec.c: Lint.
2999 Wed Dec 12 23:44:15 1990 John Gilmore (gnu at cygnus.com)
3001 Continuing Intel 960 port merge of GDB.
3003 * Makefile.dist: Merge i960 "nindy-share" files. Rename
3004 malloc.h to gmalloc.h to avoid name conflicts in /usr/include.
3005 Don't ship gdb.dvi in tar file. Link gdb with init.o, not init.c.
3006 Wack over "make depend" so it handles files in subdirectories
3007 vx-share, nindy-share, bfd, and in the current directory.
3009 * blockframe.c (get_prev_frame_info): Remove fatal error
3010 if stack not defined.
3012 * core.c (core_open, core_detach): New functions that handle
3013 the old "core-file" command as "target core" and "detach" instead.
3014 (core_file_command): Call them.
3015 (core_xfer_memory): Use common routine xfer_memory.
3017 * dbxread.c: Include a.out.gnu.h, not system a.out.h.
3018 dbxread now uses bfd for everything but symbol reading itself.
3019 BFD internals are used to drag out the relevant file offsets.
3020 (partial_symbol_file_open): Change args all around for BFD.
3022 * symtab.c: Rename "value" to "val" everywhere, so we can
3024 (symbol_file_command): New command, moved from dbxread.c
3025 and coffread.c. It uses BFD to read the file, then vectors
3026 based on its type, to dbx or coff symbol readers.
3027 * symtab.h: Extern a few vars for symbol_file_command.
3029 * target.h: Breakpoint takes a char * save area, not a char **.
3031 * valprint.c (val_print): When unpacking bitfields, offset
3032 the address in gdb of the value, if it is declared with a shorter
3033 type. Remove the last "runtime kludge test" of host byte order.
3035 * utils.c: Remove old my_bfd_read routine.
3037 * stack.c (frame_info): Use target_has_stack. Print program counter
3038 register's actual name rather than "pc", since it's called the
3039 "ip" (instruction pointer) on the i960 (sigh).
3041 * target.c (target_command): Add command for selecting a target
3042 type and calling its open routine. This is used for initiating
3043 communication with a particular target, in a generic way.
3045 * tm-i960.h: Update for modern gdb. Remove semicolons from
3046 various macros. Handle reading struct return convention, and
3047 error-out attempts to return structs with the "return" command.
3048 Be sure gdb doesn't think we know how to call functions in the
3051 * i960-tdep.c: Rename FRAME_CHAIN_VALID and FRAME_FIND_SAVED_REGS
3052 to i960_xxx in lower case.
3053 (arg_address): Circumvent errors due to LOC_ARG_BLOCK
3054 not being defined yet.
3056 * remote.c (remote_open): Call start_remote to initialize
3057 wait_for_inferior during open.
3058 (remote_xfer_inferior_memory): Return length written rather
3061 * remote-vx.c (target_command -> vx_open): Use new generic
3063 * remote-eb.c, inftarg.c, exec.c: ditto.
3065 * infrun.c: Fix comments.
3066 (attach_program -> child_open): Use new generic target command.
3067 (wait_for_inferior): Clear saved register values before target_wait,
3068 so target_wait can set some of them if convenient.
3070 * infptrace.c (fetch_inferior_registers, store_inferior_registers):
3071 Return success indicator, not void.
3072 (child_xfer_memory): Avoid fetching initial word if we'll
3073 overwrite it anyway.
3075 * infcmd.c (attach_command): Use new generic target open routine.
3076 (_initialize_infcmd): Update doc on attach and detach commands.
3077 (do_registers_info): Merge in a byte-order problem as a FIXME
3080 * findvar.c (find_saved_register): Avoid problem in current frame.
3081 (read_relative_register): Ditto.
3082 (write_register): Convert byte order on the way out.
3084 * exec.c (file_command): Add.
3085 (add_to_section_table, exec_command): Use new bfd_map_over_sections.
3086 (xfer_memory): Common function between core_xfer_memory and
3088 (exec_xfer_memory): Use it.
3090 * pn-opcode.h: Document that a "PN" is a Gould PowerNode.
3092 * breakpoint.c, breakpoint.h, symtab.h, value.h, frame.h, utils.c,
3093 valops.c, stack.c, target.c, sparc-xdep.c, source.c, printcmd.c,
3094 infcmd.c, i960-pinsn.c, eval.c, defs.h: lint and gcc -Wall.
3096 Sun Dec 2 16:45:06 1990 John Gilmore (gnu at cygnus.com)
3098 Merge Intel 960 port of gdb, continuing...
3100 * dbxread.c (partial_symbol_file_open, partial_symbol_file_read,
3101 symbol_file_command): Pass from_tty arg to hush 'em up.
3103 * coffread.c (symbol_file_command): Avoid output if from_tty != 1.
3104 Add magic numbers for 960 COFF format.
3106 Fri Nov 30 09:18:20 1990 John Gilmore (gnu at cygnus.com)
3108 Merge Intel 960 port of gdb, from Intel "1.2" release.
3110 CHANGE_LOG entries from their port, which was based on
3113 Thu Sep 6 11:02:22 PDT 1990
3114 Remove temp file if download is interrupted.
3116 Wed Aug 1 09:08:33 PDT 1990
3117 Now uses binary protocol to talk to NINDY.
3118 Old hex protocol (NINDY 2.13 and older) supported with -O switch.
3119 Times out after 5 seconds when trying to talk to NINDY.
3121 Tue May 29 12:54:49 PDT 1990
3122 Added variable baud rate (-b switch).
3123 Source code reorganization.
3125 Thu Apr 26 11:09:55 PDT 1990
3126 More cleanup of batch mode; specifically, execute "-s", "-e", and
3127 "-se" switches as soon as they are encountered on the invocation line.
3129 Fri Apr 20 13:47:15 PDT 1990
3132 Thu Apr 19 09:54:28 PDT 1990
3133 Add 'reset' command.
3135 Wed Apr 18 09:48:07 PDT 1990
3136 After opening remote tty, wait for 1 second to go by without input
3137 from it before trying to talk to NINDY (fixes problems with the
3138 Heurikon HK80/V960E).
3140 Mon Apr 4 16:33:05 PDT 1990
3141 Some output was not being suppressed in 'batch' mode.
3143 Thu Mar 22 15:31:11 PST 1990
3144 Ask user if old symbol table should be deleted when new file is
3147 Allow user to run a program downloaded before gdb960 was brought up.
3149 Correct "exec-file" help message for i80960 context.
3151 Correct bug in calculating user space address: could occasionally
3152 corrupt user program.
3154 Make sure to zero low-order bits in rip's because of bug in 960CA
3155 A-step part: could cause operation faults when "next"ing across
3158 Correct bug that made it impossible to get source line numbers for
3159 code loaded at addresses higher than 0x7fffffff.
3161 Wed Jan 10 12:43:22 PST 1990
3162 Open remote tty for exclusive use.
3164 Fri Jan 5 12:14:42 PST 1990
3165 Correct disassembly (CA manual was right after all):
3166 opcode for sysctl is 0x659
3168 Mon Oct 23 12:03:04 PDT 1989
3169 Use G960BASE and G960BIN environment variables to find 'sx' utility.
3171 Mon Oct 16 14:15:09 PDT 1989
3172 "sfr0"-"sfr31" should have been named "sf0"-"sf31"
3174 Mon Oct 2 15:56:31 PDT 1989
3176 Added 960CA disassembly support.
3178 To simplify maintenance:
3179 - eliminated use of symblic links on pinsn.c: use i960-pinsn.c
3181 - eliminated opcode.h: incorporates tables into i960-pinsn.c
3182 - moved 960-specific routines from i960-pinsn.c to i960-md.c
3183 - made disassembly interface identical to that in gdmp960.
3187 Wed Nov 28 21:32:48 1990 John Gilmore (gnu at cygint)
3189 * target.h: Allow targets to stack. Add target_has_memory,
3190 _registers, etc. Restructure memory access and "info files"
3191 to walk the target stack.
3192 * exec.c, core.c, inftarg.c, remote.c, remote-vx.c, remote-eb.c,
3193 target.c: Change tables to match target.h.
3194 * inflow.c (child_mourn_inferior): pop child_ops.
3195 (generic_mourn_inferior): Use new has_stack flag.
3196 * infptrace.c (child_xfer_memory): New memory regime.
3197 * inftarg.c (child_files_info): New "info files" regime.
3198 * remote-eb.c: New memory regime, new info files.
3199 * remote-vx.c: New memory regime, new info files. Now use
3200 separate targets for VxWorks attachment to machine, and
3201 actually running a process under VxWorks, since one has
3202 stack & execution & regs and the other doesn't.
3203 * remote.c: New memory regime, new info files.
3204 * sparc-xdep.c (fetch_core-registers): New memory regime.
3205 * target.c: New routines and support for stacked targets,
3206 new memory regime, new info files regime.
3209 Generalize section handling for an arbitrary number of sections,
3210 including use of the new BFD (binary file) library.
3211 * gdbcore.h: Add struct section_table.
3212 * exec.c (build_section_table): Iterate all sections and
3213 record what gdb needs to know about them.
3214 (exec_command): Use it.
3215 (exec_xfer_memory): Use the table.
3216 (exec_files_info): Print the table.
3217 * core.c (core_file_command, core_xfer_memory, core_files_info):
3219 * source.c (find_source_lines): Use bfd_get_mtime.
3220 * dbxread.c: Quick changes to make it compile with new BFD.
3221 * utils.c (error): Avoid using bfd_error in generic routines.
3223 * core.c (core_fetch_registers): Get from the ".regs" section of
3225 * sparc-xdep.c (fetch_core_registers): Use the .regs info.
3227 * inferior.h (attach_flag): Export.
3228 * infcmd.c (run_command): use new target_create_inferior.
3229 * infrun.c (child_create_inferior): Don't return result.
3230 * Makefile.dist (VERSION): 3.91.4.
3232 Fri Nov 23 28:15:38 1990 John Gilmore (gnu at cygint)
3234 * breakpoint.c (bpstat_num): Handle breakpoints which have
3235 since been deleted, such as temporary breakpoints.
3236 infcmd.c (program_info): ditto.
3238 * core.c (core_file_command): Display the frame where the core
3243 * remote-vx.c (target_command): Merge in target command from
3244 targ-vx.c. A few other cleanups.
3246 * TODO, Projects: Lots more stuff to do...
3248 Fri Nov 23 18:15:38 1990 John Gilmore (gnu at cygint)
3250 Massive changes to wall off the remote-debugging interface
3251 behind a function vector. The port to handle VxWorks targets
3252 is also part of this.
3254 All files: Replace references to renamed functions,
3255 remove references to remote_debugging, remove references to
3256 have_include_file, have_core_file in favor of target_has_stack,
3257 target_has_memory, etc.
3259 * Modularize the breakpoint interface.
3260 breakpoint.h (BREAKPOINT_MAX): New define sets max length of
3261 a breakpoint instruction.
3262 breakpoint.c: struct breakpoint's shadow_contents now sized as
3264 (insert_breakpoints): Vector to target to install breakpoints.
3265 (remove_breakpoints): Vector to target here too.
3266 Remove REMOTE_SA_SPARC kludges and other remote_debugging.
3267 sparc-tdep.c (single_step): Use new breakpoint interface for
3268 the single-step breakpoints.
3269 mem-break.c (memory_insert_breakpoint, memory_remove_breakpoint):
3270 New file, contains routines to insert and remove breakpoints by
3271 reading out the old contents and later replacing them. This is
3272 how ptrace breakpoints work, and many remote systems as well.
3274 * tm-vxworks68.h: New config file, overrides a few things for
3275 Wind River's preferences.
3277 * target.h: New file, for transfer vector used to talk to the
3278 inferior (child, attached, core, exec, remote, etc). All accesses
3279 to the thing being debugged should come through these vectors.
3280 target.c: New file, routines to handle transfer vector.
3281 (various files): Add transfer vectors XXX_ops for the various
3282 targets and pseudo-targets (core files, etc) we support.
3284 * breakpoint.c (bpstat_stop_status): Further explorations of
3285 watchpoints and why things don't work all the time.
3286 (bpstat_alloc): New fn to allocate a bpstat and chain it.
3288 * config.gdb: Only add "source ${srcdir}/.gdbinit" to
3289 the local gdbinit if it doesn't already have it.
3291 * core.c (core_ops): add and install.
3292 Allow core debugging without exec file.
3294 * dbxread.c (free_and_init_header_files): Merge two fns.
3295 (end_symtab): Free named symbol table when a new version comes in.
3296 (read_dbx_symtab): Relocate all kinds of symbols with base
3297 address. First step toward handling different text, data, bss
3299 (add_file_addr_command): Renamed add_file_command.
3300 (add_file_command): Vector to remote handler.
3301 Add "load" as an alias for "add-file" command.
3303 * defs.h: Allow "volatile" to be used in non-ANSI; use it for
3304 non-returning functions.
3306 * exec.c: Add exec_ops, and push it as a target when an exec
3309 * infcmd.c (run_command): Pass executable file name and arg list
3310 separately when starting an inferior. Permit "run" when no exec
3311 file is specified, for VxWorks.
3312 (detach_command): Move to child_detach in inftarg.c.
3314 * inftarg.c: New file. Unix-child-specific routines, and the
3315 child_ops structure.
3317 * inferior.h (registers): Export "registers" as the way for
3318 target dependent register handlers to find gdb's local copy of
3319 the registers. Rename "stop_after_attach" to "stop_soon_quietly"
3320 since it is now used by places that want wait_for_inferior to
3321 handle the grunge but want to see every trap from the inferior.
3323 * inflow.c (create_inferior): Pull out, and merge into infrun.c.
3324 Eliminate remote_debugging hooks in terminal handling.
3326 * infrun.c: Replace start_inferior with child_create_inferior.
3327 Move all the hair of Unix shells and ptrace idiosyncracies into
3328 child_create_inferior, so remote handlers don't have to deal.
3329 Remove running_in_shell. Rename stop_after_attach to
3330 stop_soon_quietly, and use it in a few other places where we want
3331 to just call wait_for_inferior and get control back on the first
3332 trap. trap_expected now never takes a value > 1.
3333 (init_wait_for_inferior): Initialize static vars when a new
3336 main.c (gdbinit): Add new hook for .gdbinit file name, let
3337 it be overridden by config files as GDBINIT_FILENAME.
3338 (DEFAULT_PROMPT): Add new hook for overriding (gdb) prompt.
3339 Both of these are used for VxWorks gdb.
3341 mcheck.c: rename include file "gmalloc.c" to avoid problems
3342 with system include file "malloc.c".
3344 param-no-tm.h: New include file, same as param.h but does not
3345 include the default "tm.h" file. This is used in files where
3346 the target is known, e.g. remote-eb.c or sparc-xdep.c.
3348 param.h: Now just a shell that includes tm.h and param-no-tm.h.
3350 remote-vx.c: New file, VxWorks remote debugging support. Uses
3351 RPC routines that are shared with the target system, in directory
3354 remote.c: Vectorize remote interface.
3356 source.c: Globalize source_path, and make an alias "l" for "list"
3357 since we now have the "load" command.
3359 sparc-xdep.c: Use new param-no-tm.h.
3361 symmisc.c (free_named_symtab): Add new function from Wind River.
3362 However, ifdef it out for now while we think about what it should
3365 tm-sun3.h, xm-sparc.h, xm-sun3.h, xm-symmetry.h: Move
3367 the xm- file, and change its name to CHILD_PREPARE_TO_STORE, since
3368 non-Unix-children handle this with their own code in the target
3371 Makefile.dist: Roll version to 3.92.3. Add vx-share stuff to
3372 source and target lists. Add vx-share to default list of include
3373 directories. Add new files to src and target lists: mem-break,
3374 target, inftarg, remote-eb, remote-vx, targ-vx. Be sure the
3375 ${srcdir} versions of munch and createtags are used.
3377 * valops.c (find_function_addr): Split out of call_function.
3378 (call_function_by_hand): Rename call_function; this function
3379 calls functions in the target by laboriously patching the target
3380 word-by-word with the right stack, args, regs, etc.
3383 Mon Nov 5 17:29:10 1990 John Gilmore (gnu at cygint)
3385 Handle AMD 29000 a bit better.
3387 * remote-eb.c (readchar): Mask received char log to make it readable.
3388 (remote_start): Pass arguments down to executing program.
3389 Make startaddr unsigned.
3390 infrun.c (start_inferior): Accept args, pass them to
3392 infcmd.c (run_command): Pass args down to start_inferior.
3394 * tconfig/am29k-aout, tconfig/am29k-coff: New files specifying
3395 the target object file format.
3396 tm-29k.h: Pay heed to COFF_ENCAPSULATE.
3398 * am29k-pinsn.c (print_insn): Print 0x on hex numbers in disassembly.
3399 am29k-tdep.c (examine_prologue): Better checking of function prefixes.
3401 Sun Oct 7 18:20:45 1990 John Gilmore (gnu at cygint)
3403 * Makefile.dist (VERSION): Roll version to 3.91.9 and freeze.
3404 * TODO: We did a few things, we have more to do though.
3406 * xm-sparc.h (CLEAR_DEFERRED_STORES): Define.
3407 * inflow.c (inferior_died): Clear deferred stores.
3409 * Debug problems with dummy frames and calls to the inferior.

3412 (sparc_frame_find_saved_regs): Simplify and fix what we find.
3413 (sparc_push_dummy_frame): Simplify and fix what we push.
3414 (sparc_pop_frame): Slightly more hair here, deciding whether
3415 we are restoring a saved PC or returning to a return address in %i7.
3416 * sparc-xdep.c (read_inferior_registers): Debug if valid reg is read.
3418 * utils.c (xmalloc, xrealloc): Return type depends on __STDC__.
3419 * symtab.h (xmalloc): ditto, for obstack_chunk_alloc.
3420 * obstack.h (chunkfun): ditto.
3421 * defs.h (xmalloc, xrealloc): ditto
3423 * utils.c (quit): Grab the terminal from the child if necessary.
3425 * inflow.c (term_status_command): Rename to term_info, change
3428 * sparc-pinsn.c (print_insn): Disassembly prefers real instructions.
3429 (is_delayed_branch): Speed up.
3430 * sparc-opcode.h: Add ALIAS bit to aliases. Fix up opcode tables.
3431 Still missing some float ops, and needs testing.
3433 * Support for input and output radixes other than base 10
3434 * defs.h (input_radix, output_radix): Declare.
3435 * expread.y (yyparse, parse_number): Handle changes of input
3436 radix, and ambiguous names-or-numbers in radixes >10.
3437 * printcmd.c (print_scalar_formatted): Print formatted hex
3438 numbers in varying column widths.
3439 * valprint.c (val_print): Use output_format to print scalar ints.
3440 (set_input_radix, set_output_radix, set_radix): Create.
3441 (set_output_radix): Set output_format from output_radix.
3442 (_initialize_valprint): add `set radix' but leave the others off.
3444 * main.c (execute_command): Let stupid questions be turned off.
3445 (_initialize_main): Handle "set stupidity", etc.
3447 * main.c, inflow.c, inferior.h, frame.h, command.c, defs.h,
3448 sparc-pinsn.c, sparc-xdep.c, value.h, valops.c, values.c: Lint.
3450 Tue Oct 2 11:20:02 1990 John Gilmore (gnu at cygint)
3452 * TODO, Makefile.dist, ChangeLog: Freeze for 3.91.8 release.
3453 bfd stuff is still screwed up, but with some manual work, it
3456 * breakpoint.c (bpstat_do_actions): Start over if a command
3457 proceeds the inferior, since the inferior will have stopped and
3458 will need to have its new stop-actions taken care of.
3460 * dbxread.c (read_struct_type): Expression gives Sun3 4.0.3
3461 compiler fits, simplify it.
3463 * gdb.texinfo (directory command): Doc new dir command.
3464 source.c (directory_command): "dir" now puts things on the front
3465 of the path, moves dups up front, and handles multiple names
3466 on the command line, inserting each one in order. It also
3467 blows away cached line and full_filename info.
3469 * stack.c (backtrace_command): Skip "more stack frames follow"
3472 * Change #ifndef HAVE_VPRINTF to #define MISSING_VPRINTF in
3473 xm-convex.h, xm-hp300bsd.h, xm-isi.h, xm-merlin.h, xm-news.h,
3474 xm-np1.h, xm-pn.h, xm-pyr.h, xm-symmetry.h, xm-umax.h, xm-vax.h.
3475 The only odd one was Gould NP1, which had defined vprintf to
3478 * Merge Ted Goldstein <tedg@Eng.sun.com>'s changes for epoch.
3479 printcmd.c (print_command_1): Pass 'inspect' flag down as a global
3480 variable, inspect_it.
3481 valprint.c (print_string, val_print): Use the global inspect_it
3482 to indicate whether to print in Epoch style or normal style.
3484 Mon Oct 1 23:55:26 1990 John Gilmore (gnu at cygint)
3486 * printcmd.c (call_command): add an alias for the "print" command
3487 which runs expressions and doesn't print the result if void.
3488 (print_command_1): implement it.
3490 * command.c: Remove #if 0'd code. Initialize all the fields
3491 in add_cmd (). Rename do_nothing_command to
3492 not_just_help_class_command, and make it externally visible.
3493 command.h: add user_commands to struct.
3494 * main.c (define_command): Don't overload c->function with a char
3495 string as well as a function pointer.
3497 * eval.c (evaluate_subexp): Reinstall tiemann changes to
3498 calling convention of value_struct_elt () that got dropped in
3501 * tm-sparc.h (FRAME_FIND_SAVED_REGS): move to sparc-xdep.c.
3502 sparc-tdep.c (sparc_frame_find_saved_regs): ditto.
3504 * tm-sparc.h (POP_FRAME): replace some constants with defines.
3506 * sparc-xdep.c (store_inferior_registers): defer stores to regs
3507 until a good time (e.g. when we are about to run the child),
3508 saving ptrace calls.
3509 * infrun.c (proceed): handle DO_DEFERRED_STORES.
3510 * tm-sparc.h: define DO_DEFERRED_STORES.
3512 * sparc-xdep.c (store_inferior_registers): when storing float
3513 registers, don't store stack regs too. When storing the SP,
3514 however, DO store the stack regs too. This fixes a bug in which
3515 the dummy frame is not recognized when a call_function finishes,
3516 because its frame pointer (in the stack regs) was never
3518 (read_inferior_registers): Mark WIM and TBR and FPS and CPS valid
3519 even though we don't know how to read them from an inferior.
3520 valops.c (call_function): Comment about storing SP.
3522 * infrun.c (save_inferior_status): Save away the original bpstat
3523 chain so it can be restored later. Install the copied version for
3524 use by whoever saved the status. It will be blow away by
3525 restore_inferior_status, and the original chain restored. This is
3526 important for people who have pointers into the original.
3528 * breakpoint.c, command.h, copying.awk, dbxread.c, defs.h,
3529 findvar.c, frame.h, obstack.h, obstack.c, inflow.c, value.h,
3530 main.c, printcmd.c, sparc-tdep.c, symtab.c, valprint.c: lint
3533 Fri Sep 28 20:32:46 1990 John Gilmore (gnu at cygnus.com)
3535 * Makefile.dist: Roll version to 3.91.8. Add bfd.h and bfdconfig.h
3536 temporarily to the makefile. Add am29k-opcode.h and WHATS.NEW.
3537 Add stuff.c and kdb-start.c to the OTHERS list for tar files.
3539 Fri Sep 28 19:12:12 1990 John Gilmore (gnu at cygint)
3541 * Merge Mike Tiemann's multiple inheritance changes from Sun.
3542 Store the baseclasses in a type struct starting from array element
3543 0 rather than from the unusual array element 1.
3545 dbxread.c: the above.
3546 (virtual_context): Add
3547 Read new debug information about which virtual function table
3548 a virtual function is from, and store it in fn_field.fcontext.
3550 symtab.h: Add fcontextt. Fix baseclass indices. Typo in
3551 TYPE_FN_FIELD_STATIC_P.
3553 symtab.c: the above.
3554 valops.c: the above. Handle pointer casts of object *'s.
3555 (search_struct_method): Add.
3556 (value_struct_elt): First arg is now a pointer to a value, and is
3559 valprint.c: the above.
3560 values.c (value_virtual_fn_field): Add type arg. Handle
3561 offsetting to the proper object when calling virtual fns.
3563 (baseclass_addr): Add valuep arg.
3565 * README: Document the current state of BFD config (missing).
3566 * TODO, ChangeLog, Makefile.dist: Roll version.
3567 * WHATS.NEW: Add summary of changes since 3.5.
3569 Thu Sep 27 16:23:12 1990 John Gilmore (gnu at cygint)
3571 * dbxread.c (read_struct_type): Clear bit vectors whenever
3573 symtab.c (B_CLRALL): define.
3575 * tm-sparc.h (STORE_RETURN_VALUE): Avoid clobbering types by
3576 using == rather than =. Huh... This fixes the dreaded problem
3577 wherein builtin_type_int becomes TYPE_CODE_FLT.
3579 * core.c (info_files): Show the inferior pid.
3581 * config.gdb: Avoid putting "dir" command into .gdbinit. GDB
3582 already knows how to look in the source directory.
3584 * Remove psymtab hair from many places. Remove duplicated code
3585 for searching symbol tables. Hide psymtabs from most places.
3586 Make it fast to get from a psymtab to its symtab.
3588 blockframe.c (blockvector_for_pc): Remove psymtab hair.
3589 coffread.c (psymtab_to_symtab): Rename to psymtab_to_symtab2.
3590 mipsread.c (psymtab_to_symtab): Rename to psymtab_to_symtab2.
3591 dbxread.c: export psymtab_to_symtab, make it work if called N times.
3592 (psymtab_to_symtab): Rename to psymtab_to_symtab2. Initialize
3593 new symtab completely. New psymtabs get symtab pointer
3594 initialized to zero. Remove MI warning printf.
3595 symtab.h: Comments. Add psymtab to symtab pointer.
3596 (PSYMTAB_TO_SYMTAB): New macro.
3597 symtab.c: use PSYMTAB_TO_SYMTAB. Add psymtab_to_symtab and export it.
3598 source.c: use PSYMTAB_TO_SYMTAB. Remove symtab version and
3600 stack.c (backtrace_command): Avoid pre-pass to read symbols, if
3602 (print_frame_info): Avoid special-casing symbols that have not yet
3605 * source.c (open_source_file): Quick path if we have already
3606 located the source file by its full name.
3608 * symtab.c (lookup_symbol): Use find_pc_symtab rather than
3609 find_pc_psymtab. When a name is found in the misc function
3610 vector, search the symbol table for its mangled name, not the
3611 name that the user typed.
3613 * bfd.h: Fix missing comment terminators, make #endifs match.
3615 * valarith.c (value_less): Handle unsigned int comparisons.
3616 Add FIXME about pointer compares, which assume host and target
3617 pointers are the same.
3619 * command.c (do_nothing_command): lint
3620 dbxread.c: lint. Remove sort_syms. Document C++ visibility info,
3621 fix comments on debug symbol format for visibility. Actually set
3622 visibility of symbols.
3623 main.c (echo_command): lint; use <readline/history.h>.
3624 tm-sparc.h (FRAME_FIND_SAVED_REGS): lint
3625 obstack.h (_obstack_blank): Rearrange pointer math to avoid
3626 pointing past end of allocated memory; saber complains.
3627 obstack.h: Declare the external functions that we use.
3628 valarith.h: use <string.h>
3629 solib.c (solib_add): lint.
3631 Fri Sep 21 17:05:19 1990 John Gilmore (gnu at cygint)
3633 * main.c (initialize_main): Default info_verbose to off, now that
3634 symbol reading is fast.
3635 (quit_command): Avoid clobbering exec_bfd while quitting.
3637 * Initial BFD (binary file diddling library) merger:
3638 coffread.c: Change AOUTHDR to struct exe_hdr.
3640 core.c: initialize initialized data at compile time.
3641 (core_file_command): Move from coredep.c, convert to bfd.
3642 (xfer_core_file): Convert to bfd.
3643 exec.c (exec_file_command): use bfd routines.
3645 mips-tdep.c: Remove exec_file_command and friends.
3648 * coredep.c: (fetch_core_registers) Convert core_file_command to
3649 fetch_core_registers.
3650 mips-xdep.c, sparc-xdep.c, sun3-xdep.c: ditto.
3652 * utils.c: (error): Bogus crap, FIXME, to print bfd errors.
3653 (my_bfd_read): More bogosity, which I don't think we call.
3654 (program_name): Remove this atrocity asap!
3656 Wed Sep 19 13:36:41 1990 John Gilmore (gnu at cygint)
3659 values.c: allocate_repeat_value was not clearing the
3660 optimized_out field.
3661 (value_static_field): minor stylistic fix (wrong macro was used).
3662 valops.c (value_struct_elt_for_address): didn't work for C++
3665 * signame.c (_initialize_signame): Initialize signal names once.
3667 * breakpoint.h, command.c, copying.awk, defs.h, environ.c,
3668 exec.c, frame.h, infcmd.c, inferior.h, main.c, munch, sun3-xdep.c,
3669 symtab.h, tm-29k.h, valprint.c, value.h, values.c: Lint.
3671 * remote-eb.c: Support user-settable baud rates on the serial port.
3673 * tm-sun3.h (PREPARE_TO_STORE): fix typo.
3675 Fri Sep 14 13:28:29 1990 John Gilmore (gnu at cygint)
3677 * tconfig/sun3os4: Remove warning about native assembler,
3678 since it also occurs in the xconfig file.
3680 * findvar.c (registers): Allocate some slop after `registers'
3681 to prevent stray accesses from trashing the next variable.
3683 * tm-68k.h (REGISTER_BYTES): Allocate the right number of bytes
3684 on the sun-3, by changing the #ifdef from `sun3' (which is not
3685 defined by cc) to `sun'. Symptom was trashed builtin_type_XXX
3686 vars, which happened to follow `registers' in the executable.
3688 * readline/history.c (history_search): Heed gcc-2's advice
3689 and parenthesize && inside ||).
3691 * am29k-opcode.h, am29k-pinsn.c, am29k-tdep.c, remote-eb.c,
3692 tm-29k.c: Insert FSF copyright headers.
3694 * remote-eb.c: Better comments.
3696 * Makefile.dist: Update to 3.91.6.
3697 * TODO: note PREPARE_TO_STORE problem.
3699 Thu Sep 13 09:52:33 1990 Jim Kingdon (kingdon at cygint)
3701 * stack.c (frame_info): Only use FRAME_FIND_SAVED_REGS if defined.
3703 * remote.c: Wrap the whole file in #if !defined (SPECIAL_REMOTE).
3705 * infrun.c (wait_for_inferior, at end): Don't set up
3706 prev_* if the inferior no longer exists.
3708 * inferior.h (CALL_DUMMY_LOCATION): New macro, to replace
3709 CANNOT_EXECUTE_STACK.
3710 valops.c (call_function): Use it.
3712 * tm-convex.h: Add CALL_DUMMY_LENGTH for use by PC_IN_CALL_DUMMY.
3714 * inferior.h (PC_IN_CALL_DUMMY): New macro.
3715 infrun.c (wait_for_inferior, 2 places): Use it.
3717 * values.c (value_being_returned): Only use
3718 EXTRACT_STRUCT_VALUE_ADDRESS if defined.
3720 * Move PREPARE_TO_STORE from xm-sun3.h to tm-sun3.h to do the
3721 right thing for remote-eb.c.
3723 * sun3-xdep.c: Remove extraneous call to remote_store_registers.
3724 * sun386-xdep.c, hp300hpux-xdep.c, sparc-xdep.c: Ditto.
3726 * blockframe.c: Put get_frame_saved_regs inside #if !defined
3727 (FRAME_FIND_SAVED_REGS).
3729 * findvar.c ({fetch,store}_registers): Check for
3730 REMOTE_{FETCH_STORE}_REGISTER macro.
3732 * findvar.c (get_saved_register): Add argument lval and
3733 change meaning of argument addr.
3734 findvar.c: Change calls to get_saved_register to reflect
3735 new calling convention.
3736 valops.c (value_assign): Use get_saved_register instead of
3737 find_saved_register.
3739 Sun Sep 2 12:40:20 1990 Jim Kingdon (kingdon at cygint.cygnus.com)
3741 * coffread.c (read_one_sym): Make temp_aux an AUXENT, not
3742 an (uninitialized) pointer to one. Use "&" when passing it
3745 Fri Aug 31 22:57:54 1990 Jim Kingdon (kingdon at cygint.cygnus.com)
3747 * coffread.c (getfilename): Use DGUX x_offset and x_name if
3750 * coffread.c (symbol_file_command): Put semicolon after
3752 Put safe_to_init_tdesc_context in #if defined (TDESC).
3753 Put #ifdef TDESCs in 1st column for non-ANSI cpp's.
3754 coffread.c: #include <sys/stat.h>.
3755 (read_coff_symtab): Typo: in_source_files -> in_source_file.
3756 Add missing ')' in check for "lc%" and friends. Remove
3758 Declare read_one_sym() at top of file.
3759 (read_file_hdr): Put in extra #ifdefs so MC68MAGIC and
3760 MC68WRMAGIC can have the same value without causing a duplicate
3763 Thu Sep 13 15:55:36 1990 John Gilmore (gnu at cygint)
3765 * Allow a Makefile to be built without building the
3766 tm and xm file links that screw up builds in subdirectories.
3767 This is done with `config.gdb none', then you can do things
3768 like `make gdb.tar.Z'.
3769 * tconfig/none: Config file for no target system
3770 * xconfig/none: Config file for no host system
3771 * config.gdb: If no TM or XM files are called out by the
3772 host or target file, don't make links for them.
3774 * cplus-dem.c: Add documentation.
3776 * dbxread.c (read_ofile_symtab): Turn a fatal error into a
3777 simple error, so the user's gdb doesn't crash due to some object
3778 file problem (e.g. somebody is rebuilding the file out from under
3781 * printcmd.c (print_address_symbolic): demangle the symbol.
3783 * Makefile.dist (OTHERS): Remove tdesc-lib because it has
3784 Motorola copyrights in it. Make "make gdb.tar.Z" work.
3785 (alldeps.mak): sort and uniq all results from this; duplicates
3786 hose gdb.tar.Z link building. Remove RCS files from
3787 tconfig and xconfig. Add config files for sun386. Add
3788 a few odd files to OTHERS and HFILES.
3790 Mon Sep 10 21:20:24 1990 John Gilmore (gnu at cygint)
3792 * Makefile.dist: Pull solib.c to tconfig/sun?os4.
3793 Roll version number to 3.91.5. Make lint work in bindir.
3795 * README: Document cross-debugging and new file structure.
3797 * blockframe.c: Lint. Include "value.h" to declare read_register.
3798 (find_pc_partial_function): remove duplicate line.
3800 * command.h: Lint. Declare error_no_arg and dont_repeat.
3802 * tm-news.h: Remove inadvertently duplicated stuff.
3804 * mipsread.c: Remove cache_pc_function stuff, now done cleanly.
3805 Clean up usage of misc_function_type. Declare some CORE_ADDRs.
3807 * config.gdb: Allow `config.gdb host target' form. Clean
3808 up previous change that printed bogus messages when you just said
3811 * core.c: #include "command.h" for lint.
3814 * main.c: Remove some casts of enums. Lint.
3821 * printcmd.c (initialize_printcmd): Fix thinko in inspect cmd.
3823 * sparc-tdep.c (isannulled): Take instruction as parameter, don't
3824 read it from memory. This will allow us to save ptrace calls
3825 eventually. Changed caller single_step too.
3827 * sparc-xdep.c (fetch_inferior_registers): Avoid reading regs
3828 that we aren't going to use, saving many ptrace calls, especially
3829 when watchpointing or single stepping. Use some #define's for
3831 (store_inferior_registers): Ditto.
3832 (core_file_command): Use some #define's for constants.
3834 * tm-sparc.h: Add #define's for some register numbers, so we
3835 can eliminate the use of random constants in sparc-xdep.c.
3837 * stack.c (frame_command, print_frame_info, up_command,
3838 down_command) Remove frame_changed, since it
3839 causes a bug and doesn't seem to do anything useful. In some
3840 places it was used as a flag, in others as a stack level (?).
3842 * utils.c: Use MISSING_VPRINTF rather than HAVE_VPRINTF, so the
3843 default is to use the portable (vprintf) version rather than the
3845 * xm-news.h (MISSING_VPRINTF): Add.
3847 * valprint.c (val_print): Demangle fancy vtbl printouts. Lint.
3849 Sat Sep 8 00:24:12 1990 John Gilmore (gnu at cygint)
3851 * Remove stuff that forces -Bstatic linking of gdb, and warnings
3852 about linking debugged programs -Bstatic in the sun?os4 config
3853 files in tconfig and xconfig subdirectories.
3855 * main.c (main): Remove unreached exit(0) now that we exit
3858 * Create TODO file for online bug list. There are too many
3859 "little" bugs to keep track of on paper.
3861 * Change Projects file to refer to bug-gdb@cygnus.com
3862 rather than kingdon@ai.
3864 Fri Sep 7 23:35:15 1990 John Gilmore (gnu at cygint)
3866 * Makefile.dist (VERSION): 3.91.4 now.
3868 * symtab.c (init_misc_bunches): Rename from init_misc_functions.
3869 (condense_misc_bunches): Add sanity check that misc_count is
3870 the same as the number of symbols in the bunch.
3872 * coffread.c: rename init_misc_bunches. Pass an argument
3873 to condense_misc_bunches (a zero).
3875 * dbxread.c (partial_symbol_file_read): Call init_misc_bunches
3876 every time we are called; don't rely on our caller to do it.
3877 (add_file): Remove call to init_misc_bunches.
3879 * mipsread.c: Only warn, don't error, if unknown symbol types.
3880 This keeps an old gdb from falling on its face if it sees newly
3881 extended symbol info. Rename init_misc_bunches.
3883 Fri Sep 7 22:58:15 1990 John Gilmore (gnu at cygint)
3885 * Merge in changes from Per Bothner for DECstations and other
3886 MIPS stuff. The rest is Bothner speaking:
3888 The next message is a merger of Alessando Forin's mips port with
3889 mine. I've tried to use my good if biased judgment to get
3890 the best of both. It *does* need testing.
3892 Some of the changes are general, *not* mips-specific.
3895 Didn't believe in little-endian bit order.
3896 There are still inconsistencies about whether flags
3897 like BITS_BIG_ENDIAN are integer (#if ...) or
3898 boolean (#ifdef ...). I tried to paper over them.
3900 dbxread.c,coffread.c,mipsread.c,symtab.c,symtab.h:
3901 Moved some misc_function code that was common to
3902 {dbx,coff,mips}read.c to symtab.c.
3903 In the process, I think I cleaned things up a bit.
3904 At the same time, moved obsavestring and obconcat to symtab.c.
3907 Removed obsolete condense_addl_misc_bunches (use
3908 condense_misc_bunches(1) instead).
3911 Needed to include <sys/dir>, at least on DECstations.
3913 valops.c, mips-tdep.c, tm-mips.h:
3914 Added PUSH_ARGUMENTS macro to support funny argument-pushing
3915 conventions (when STACK_ALIGN is insufficient).
3916 Needed on mips, where doubles need 8-byte alignment,
3917 but ints only need 4.
3920 Removed cruft that was not being used.
3921 Merged in many fixes (most from Frank Yellin, fy@lucid.com).
3924 Print $ before register-names (I think that makes things a little
3926 Never print two instructions, even if one delays.
3927 Removed hex-disassemble set_cmd. (This is not mips-specific,
3928 so I think the argument is whether it is generally worthwhile or not.
3929 I'm inclined to think not, given how easy it is to
3930 convert between radixes in gdb.)
3933 This is basically Alessando's code.
3934 It doesn't use obstacks; I changed it to use obstacks
3935 in a few minor places where using malloc causes a
3936 memory leak. (Probably, more places could/should be changed.)
3937 I added record_misc_function where it was missing.
3938 In symbol_file_command and add_file_command, I tried
3939 to make the code consistent with more recent versions.
3940 Minor sylistic changes in parse_procedure.
3941 Make a .gdbinfo. psuedo-symbol point back to the real
3942 procedure symbol (using the isym field).
3945 This is basically from my port, but with a lot of details
3946 and a number of routines merged in from Alessando's version.
3947 I basically used my code "raw" backtrace (use heuristics
3948 from the actual code, rather than symbol table info) - though
3949 the idea is Alessandro's. I feel my code is a little cleaner
3950 here, particularly in being a little more flexible, such as being
3951 able to handle gcc-produced code (which it now can).
3952 It also doesn't do frame caching (which is not useful
3953 more recent gdb versions).
3954 I also used my code for push_/pop_dummy, more or less.
3955 I tried to incorporate AF's code for testing sigtramp
3956 while backtracing; I probably got it wrong.
3957 Added mips_print_register, which tries to scrunch as much
3958 information as possible on a screen...
3959 Removed the skip-prologue set_cmd. As with hex-disassemble (see
3960 under mips-pinsn.c), I don't see anything mips-specific here,
3961 and I don't see it being all that useful anyway.
3964 Added a $fp psuedo-reg distinct from $fp (nice for gcc).
3965 Use more register names (rather than hard-cases numbers).
3967 Thu Sep 6 18:33:15 1990 John Gilmore (gnu at cygint)
3969 * Hack up 3.90.11 changes:
3971 * Makefile.dist (depend): parameterize $(GCC).
3972 Add solib.c and solib.o.
3973 (readline): Fix vpath for both absolute or relative SRCDIR.
3975 * blockframe.c: Fix from Schaefer@asc.slb.com for shared libs.
3976 Also, let the part I didn't understand at least compile so
3977 I can test the rest. FIXME.
3979 * dbxread.c: Fix thinko using strcmp.
3980 (init_psymbol_list): declare static.
3981 (partial_symbol_file_open): Comment cleanups better, avoid
3982 cleaning up the string table since the caller will do that.
3983 Move the stat for mod time into symbol_file_command, temporarily.
3984 (There should be a mod time for each symbol file, eventually,
3985 to control its rereading. FIXME.)
3987 * infptrace.c (PT_WRITE_D): use same value as PT_WRITE_I for
3988 SunOS, which gives error for shared libs otherwise. (From
3989 Schaefer, probably FIXME needs work for portability.)
3991 * solib.c: Move #include "param.h" to work.
3992 Lowercase all the Uppercase Letters In the Messages.
3993 (find_solib): Clean up inferior_so_name for debug printouts.
3994 Allow no argument, to mean all shared libraries.
3996 * symmisc.c: include param.h to get CLEAR_SOLIB.
3998 Wed Sep 5 18:00:08 1990 John Gilmore (gnu at cygint)
4000 * Merge in Kingdon's changes from FSF: the diffs from 3.90.9
4001 to 3.90.11. ChangeLog entries below are from this.
4003 Wed Jun 13 09:17:39 1990 Jim Kingdon (kingdon at mole.ai.mit.edu)
4007 * Makefile.dist (HFILES): Add tm-sunos.h.
4009 Tue Jun 12 16:15:26 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
4013 * Makefile.dist (gdb.tar.Z): Change linking of config so it works.
4015 Thu Jun 7 16:22:27 EDT 1990 Jay Fenlason (hack@ai.mit.edu)
4017 * sparc-opcode.h Added single-operand version of rett.
4019 Mon Jun 4 18:12:31 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
4021 * m-sparc.h (REG_STRUCT_HAS_ADDR, STRUCT_ARG_SYM_GARBAGE):
4022 Put parens around gcc_p in expansion.
4024 Thu May 24 15:44:51 1990 Jim Kingdon (kingdon at mole.ai.mit.edu)
4026 * utils.c (lines_to_list): Return 10 if lines_per_page == 0.
4028 Wed May 23 16:36:04 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
4030 * Changes for Sun shared libraries:
4031 blockframe.c (find_pc_partial_function): If a non-text symbol
4032 is found, set *address = pc - FUNCTION_START_OFFSET.
4033 breakpoint.c (insert_breakpoints) [DISABLE_UNSETTABLE_BREAK]:
4034 Disable breakpoints instead of giving an error.
4035 source.c (select_source_symtab): Initialize cs_pst.
4036 symmisc.c: Call CLEAR_SOLIB if defined.
4037 symtab.h: Make text{low,high} CORE_ADDR not int.
4038 (psymtab): New field addr.
4040 dbxread.c: Move DECLARE_FILE_HEADERS outside functions.
4041 (record_misc_function): Give correct type for N_DATA symbols.
4042 (condense_misc_bunches): do "misc_function_count = j" regardless
4044 Take code which is shared between symbol_file_command and
4045 add_file_command and put it into partial_symbol_file_{open,read}.
4046 Split add_file_command into add_file_command and add_file.
4047 Make psymtab_to_symtab read in the string table if the file
4049 Two new parameters to read_dbx_symtab and start_psymtab.
4050 tm-sunos.h: New file.
4052 Tue May 22 17:43:03 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
4054 * infcmd.c: Change cont_command to continue_command and "cont"
4057 Mon May 21 14:41:41 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
4059 * breakpoint.c (enable_breakpoint): Get value of watchpoint.
4061 * defs.h [sparc]: Use <alloca.h> regardless of __GNUC__.
4063 * values.c (USE_STRUCT_CONVENTION): Check for structures of
4064 size 1,2,4,8 rather than size < 8.
4066 * dbxread.c (dbx_lookup_type): Do f->length *= 2 as many times
4067 as necessary, not just once.
4069 * sparc-opcode.h: Add a bunch of new opcodes which Sun as supports.
4071 Thu May 17 15:04:09 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
4073 * {t,x}m-sun386.h, sun386-xdep.c, {x,t}config/sun386
4075 * tm-news.h: Add CALL_DUMMY_*.
4077 * tm-68k.h: Remove duplicate comment at FRAME_FIND_SAVED_REGS.
4079 * config.gdb: In list_host, list_target, use ${i}, not $i.
4081 Tue May 15 21:27:12 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
4083 * source.c (find_source_lines) [BROKEN_LARGE_ALLOCA]: Use xmalloc.
4085 * sparc-opcode.h: Change all store floating-point state register
4086 instructions to have the right match & lose fields.
4088 Sat May 5 12:39:18 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
4090 * Makefile.dist: Move -I${srcdir} to GLOBAL_CFLAGS and pass
4092 config.gdb: If srcdir != ., create readline directory and
4093 copy a makefile into it.
4095 * wait.h, infrun.c: Change WRETCODE to WEXITSTATUS for
4096 consistency with POSIX.
4098 * breakpoint.c (bpstat_stop_status): Disable watchpoint
4099 when we exit its exp_valid_block.
4101 Tue Sep 4 11:46:46 1990 John Gilmore (gnu at cygint)
4103 * Makefile.dist: Bump version to 3.91.3.
4105 * Clean up handling of breakpoint commands (somewhat).
4106 Prompted by Tiemann bug report "cont 10" doesn't work any more.
4108 inferior.h: Add breakpoint_proceeded to inferior status struct
4109 and globals; save it and restore it.
4110 (clear_breakpoint_commands): Cleanup, remove old #define.
4112 infrun.c (clear_proceed_status): Set breakpoint_proceeded.
4113 (save_inferior_status, restore_inferior_status): handle it also.
4114 (proceed): Remove earlier code that set breakpoint_proceeded.
4115 It is now set only in clear_proceed_status.
4116 (clear_proceed_status): Cleanup, use bpstat_clear rather
4117 than clear_breakpoint_commands. No callers need the stop_bpstat
4118 between clear_proceed_status and proceed.
4120 infcmd.c: Add breakpoint_proceeded definition and comment.
4121 (cont_command, jump_command, signal_command): Move call to
4122 clear_proceed_status right next to call to proceed.
4124 breakpoint.c (bpstat_do_actions): Avoid clobbering our
4125 caller's argument while running down the chain of breakpoints.
4126 Use new variable "breakpoint_proceeded" to determine when
4127 a command that it executes moves the inferior past the
4129 (bpstat_clear): Handle NULL argument.
4130 (bpstat_clear_actions): Avoid useless call to
4131 breakpoint_auto_delete.
4132 (delete_breakpoint): Clean up bpstat's that are pointing to
4133 the deleted breakpoint from the stop_bpstat chain.
4134 (breakpoint_auto_delete): Simplify.
4136 * Clean up handling of EOF, error on stdin, etc. This was
4137 prompted by a network problem that caused gdb to go into an
4138 infinite loop filling up its malloc'd memory.
4140 main.c (return_to_top_level): Cleanup: call bpstat_clear_actions,
4141 not clear_breakpoints_commands, which is now gone.
4142 (main): If command_loop returns (e.g. from EOF on stdin), do
4143 a quit_command (looping back to command_loop if quit_command
4144 doesn't really quit).
4145 (command_loop): check result from command_line_input and
4146 exit if it returns NULL, rather than passing the NULL to
4148 (gdb_readline): Free malloc'd result space before returning
4151 * utils.c (query): Handle C-d to mean "yes", just as if the
4152 input was not a terminal. Also avoid infinite loop if EOF
4153 occurs in mid-input-line before newline. This allows
4154 query to be used at EOF on stdin with reasonable results.
4156 * infrun.c (proceed): Set breakpoint_proceeded.
4158 * values.c (value_as_long): Avoid infinite recursion for enums.
4159 (_initialize_values): Fix typo in help msg (kingdon).
4161 * Makefile.dist (RL_LIB): Use RL_LIB_DEP for dependencies,
4162 RL_LIB for linking. This allows -lreadline for linking
4163 and nothing for dependencies, once readline is a real library.
4165 * config.gdb: Jim Kingdon: give useful error message if the
4166 host or target type is not recognized.
4168 * defs.h (alloca): SPARC <alloca.h> does not declare alloca,
4169 it just defines it. Dumb, but deal with it.
4171 * Jim Kingdon suggests:
4172 in xconfig/sun3os4, CFLAGS should be XM_CFLAGS.
4174 Wed Aug 29 18:03:27 1990 John Gilmore (gnu at cygint)
4176 * Makefile.dist (VERSION): Bump version # to 3.91.2.
4178 * Clean up Bothner's changes.
4180 * blockframe.c (clear_pc_function_cache): New function.
4181 * blockframe.c: remake cache_pc_function_* static.
4182 * dbxread.c (symbol_file_command): remove references to
4183 cache_pc_function_* variables.
4184 * dbxread.c (read_struct_type): Use VOFFSET_STATIC.
4185 * printcmd.c: Avoid kludging a global variable (addressprint)
4186 to avoid printing the address of a string twice. Instead,
4187 pass the format letter 's' down low enough that it can be seen
4188 to avoid this problem.
4189 (print_formatted): Pass format arg to value_print.
4190 (restore_addressprint): Remove function.
4191 (do_examine): Avoid hacking addressprint, cleanups and such.
4192 (print_frame_args): Add a comment to a Bothner change.
4193 * symtab.h: define VOFFSET_STATIC and use it instead of "-1".
4194 * symmisc.c (free_all_symtabs): Call clear_pc_function_cache
4195 to wipe out the values cached in blockframe.c.
4196 * symtab.c (find_method): Add comment saying how big you must
4197 allocate to be "big enough". Per being terse again.
4198 * valprint.c (val_print): Handle format letter "s" to print
4199 strings without addresses. Add comment to vtbl printing code
4200 which casts with wild abandon. Rearrange reference-printing
4202 @0xaddr: value (print w/addressprint)
4203 value (print w/~addressprint)
4204 @0xaddr (parameter lists w/addressprint)
4205 or nothing (parameter lists w/o addressprint)
4207 Tue Aug 28 10:47:18 1990 John Gilmore (gnu at cygint)
4209 * Merge more changes from Per Bothner:
4211 Gdb's handling of TYPE_CODE_REF was so counter-C++ (and otherwise
4212 annoying) that I tried to improve it. Here are my suggestions.
4214 These patches all attempt to handle TYPE_CODE_REF (as in C++) better.
4217 Do automatic de-reference when taking the address of a reference.
4219 Don't deref_ref when printing parameter lists.
4221 More attempts at treating refernences properly.
4223 In val_print, if deref_ref==0, don't print dangling " = ".
4225 Add COERCE_REF macro, which de-references an REF.
4227 * Merge changes from Per Bothner:
4229 * Fixed (Sony news)-specific configuration problems.
4230 * Fixed other problems with using vanilla pcc and libc (enum problems;
4231 assumption that vsprintf exists).
4232 * Some major speed-ups (finc_pc_partial_function now caches a match;
4233 parsing avoids duplicate symbol_lookup calls).
4234 * Changed handling of baseclasses (no longer use baseclasses field
4235 of struct type, use the first n_baseclasses fields instead).
4236 * Various minor changes/fixes, most C++-related.
4239 Cache the most previous match from find_pc_partial_function.
4240 (Save both low and high ends of matching function's pc range.)
4241 This speeds up the loop of infrun.c:wait_for_inferior quite
4242 a bit, and makes step/next commands much zippier.
4244 Added an enum->int cast (otherwise, some compilers barf).
4246 No longer set baseclass offset to 0, since multiple
4247 inheritance now mostly works.
4248 Added a number of casts, to shut up compiler warnings
4249 (after stabs where made enums, not ints).
4250 When discarding a symbol table (in symbol_file_command),
4251 must clear the cache introduced in blockframe.c.
4252 Don't convert $vtbl_ptr_type to vtbl any more.
4253 Get rid of TYPE_BASECLASEES and baseclass_vec (see also symtab.h).
4254 Mask off sign bit emitted by g++ for virtual table offset.
4255 Set voffset to -1 (not 1) for static member functions.
4257 Changed parsing/lexing of names to avoid doing symbol lookup twice
4258 (once when lexing to determine symbol class, once for real).
4259 Now only call symbol_lookup once. Fields of 'this' win especially big.
4261 Subpress printing addr twice in the case of 'x/s addr'.
4263 lookup_basetype_type is no longer used.
4264 Add find_methods as recursive helper function to decode_line_1.
4265 This allows multiple inheritance to work.
4266 Also, once one or more matches has been found, do not look in
4267 base-classes. (Baseclass methods would be overridden, anyway.)
4269 Removed baseclasses array in struct type.
4270 Instead of using baseclasses[i], use fields[i-1].
4271 Added virtual_field_bits[i] to indicate if the i'th baseclass is virtual.
4272 Changed sign convention of voffset (previous was inconsistent).
4274 Some macros (CALL_DUMMY and relatives) were missing. Put them back.
4276 Used to assume existence of vsprintf. Re-written to not need it
4277 if HAVE_VPRINTF is undefined.
4279 typecmp was too pessimistic. Made it less so.
4281 Don't print space after address.
4282 If vtable points to a misc symbol (with 0 offset), print it,
4283 since that indicates the actual class of the object.
4284 Changed ype_print_derivation_info to use new inheritance
4285 scheme (without baseclasses vector).
4287 In value_primitive_field, fixed some bugs left over from previous set of fixes.
4288 Also, changes needed because TYPE_BASECLASSES were removed.
4290 REGISTER_U_ADDR didn't work for PC. Rewrote to use an array.
4292 Tue Aug 21 20:08:54 1990 John Gilmore (gnu at cygint)
4295 If there is no path set, and the symbols don't indicate what directory
4296 a file was compiled in, look in the current directory. But either
4297 a path or a known compilation directory will prevent this.
4300 Three independent bug fixes:
4301 * Remove the #if 0 block that breaks some stuff.
4302 * SunOS 4.1 fixed the promoted-parameter-wrong-addr bug in Sun C;
4303 adapt gdb to either SunOS 4.0.* or 4.1.
4304 * MAX_OF_TYPE and MIN_OF_TYPE thinko. By tedg@sun, I think.
4307 Instantiate the class T when looking for methods in it. (Tiemann@sun)
4310 (type_print) Demangle the name being printed.
4311 (type_print_base) Handle botched demangling without coredump (tiemann).
4314 (check_stub_method): Document routine.
4315 (tiemann) fix bug for no-arg functions
4316 Avoid clobbering beyond end of malloc'd storage.
4317 Terminate the argument list properly.
4319 Sat Aug 18 01:29:59 1990 Per Bothner (bothner@cs.wisc.edu)
4321 * Changes merged by John Gilmore:
4324 In breakpoint_1, use new print_address_symbolic instead
4325 of find_pc_partial_function. (This forces use of assembler-level
4326 addresses, and avoids misleading non-mangled source-level names.)
4328 Generalize ansi argument such that -1 means skip arglist totally.
4329 Removed global variable print_ansi_qualifiers (which made
4330 code non-reentrant), in favor of extra explicit arguments
4331 to internal routines.
4333 Add new helper function print_address_symbolic.
4334 Use find_pc_misc_function instead of find_pc_partial_function
4335 (since we want assembler-level symbols here).
4337 Print unknown function as just "f (...)", not "f (...) (...)".
4338 Use new fputs_demangled explicitly.
4340 Fixed a typing violation (problem: value.h cannot be imported
4341 without renaming many variable in this file).
4342 lookup_symbol: If no matching misc_func, look for a C++-mangled name.
4343 decode_line_1: Moved forward some never-reached code.
4344 Made decode_line_2 skip function prologues correctly.
4346 fputs_filtered should not demangle by default.
4347 Add new fputs_demangled to demangle on demand..
4349 Change value_struct_elt to use value_primitive_field (using recursive
4350 utility function search_struct_field). This allows foo.bar to work
4351 for multiple inheritance (so far only for data fields).
4352 Change check_field in the same way (recursive helper function
4353 to support multiple inheritance).
4354 (Note: there are more of these problems that I haven't fixed.
4355 Any code that says TYPE_BASECLASS (t, 1) is probably wrong.)
4356 value_of_this: 'this' symbol name is now just "this", note "$this".
4358 Don't print static members.
4359 Avoid printing "members of <type>" if there are none.
4360 Simplified type_print_derivation_info by merging duplicate code.
4361 Remove useless blank lines in type_print_base (ptype command).
4363 Added declaration of new routine value_primitive_field.
4365 Added value_primitive_field which is generalized version of
4366 value_field that can handle multiple inheritance (non-zero offsets etc).
4367 Re-implemented value_field to call value_primitive_field.
4369 Fri Aug 17 23:33:44 1990 John Gilmore (gnu at cygint)
4371 * infcmd.c -- insert else to avoid 'delete env' coredump when you
4372 delete the whole environment. Karl Berry reported the bug.
4373 * source.c - fix openp to avoid //'s in filenames, which
4374 trigger an Emacs bug causing it to not be able to find files
4375 when running gdb in a window.
4376 * dbxread.c - zap the #if 0 that botches the add-file code.
4377 It seems to work a lot better without all the code commented out.
4379 Fri Jul 20 16:58:46 1990 John Gilmore (gnu at cygnus.com)
4381 * Merge Tiemann's and Ted Goldstein's changes, detailed below,
4384 Tue Jul 17 19:34:33 1990 Ted Goldstein (tedg at golem)
4386 * Makefile - added a ${CFLAGS} to a couple of entries,
4387 added remote-sa.sparc.c
4388 * added remote.sa-sparc.c, a modification of remote.c
4389 which conducts a dialog directly with the SparcStation prom.
4390 * breakpoint.c, infrun.c, sparcdep.c added
4391 remote_insert_breakpoint(), and remote_remove_breakpoint()
4392 to breakpoint.c instead of directly writing breakpoint instructions.
4393 * sparcdep.c on remote_debugging,there is no need
4394 to remove signle step breakpoint instructions.
4395 * main.c added "-epoch" flag and "int epoch_interface" to main.c
4397 * printcmd.c - epoch interface sends lisp expressions to open up
4398 epoch windows on inspection.
4399 * valprint.c - added arrayprint, and addressprint and made adding
4400 format controls easier
4401 * wait.h added a couple of undef's because we were getting
4402 complaints about WSTOPSIG and WTERMSIG begin redefined.
4405 Wed Jul 4 05:27:51 1990 Michael Tiemann (tiemann at masham)
4407 * symtab.c (decode_line_1): Add support for handling method stubs
4408 in the type information.
4410 Tue Jul 3 09:39:18 1990 Michael Tiemann (tiemann at masham)
4412 * values.c (baseclass_addr): Run loop from INDEX+1 to
4413 N_BASECLASSES; otherwise, we can still get into a loop.
4414 @@ This should be restructured to use a cleaner search strategy.
4416 Sun Jul 1 12:28:51 1990 Michael Tiemann (tiemann at masham)
4418 * dbxread.c (define_symbol,read_type): Grok GNU C++'s new
4419 abbreviation "Tt" for tags which have the same name as their
4422 Fri Jun 29 01:03:46 1990 Michael Tiemann (tiemann at masham)
4424 * symtab.c (list_symbols): add ability to set breakpoints on all
4425 the functions which match a particular regular expression.
4427 Tue Jun 26 04:26:29 1990 Michael Tiemann (tiemann at masham)
4429 * cplus-dem.c (cplus_demangle): New parameter ANSI says whether we
4430 should print ANSI qualifiers (such as `const' and `volatile').
4431 All callers changed to call with ANSI == 1, except from
4432 `check_method_stub', which uses old-style syntax.
4434 * symseg.h (struct fn_field): Remove unneccessary `args' field.
4435 * symtab.h (TYPE_FN_FIELD_ARGS): Redefined.
4437 * values.c (check_stub_method): New function.
4439 * cplus-dem.c (do_type): Handle "long long" (encoded as 'x').
4441 * dbxread.c (read_type): Handle new GNU C++ method type stubs.
4442 * valprint (type_print_base): Ditto.
4444 * symtab.c (gdb_mangle_typename): New function.
4446 Tue Jun 5 00:18:43 1990 Michael Tiemann (tiemann at gzilla)
4448 * breakpoint.c (catch_command): New function. Provides a
4449 mechanism to set breakpoints based on catch clauses.
4450 (disable_catch): Similar, but disables breakpoints on catch
4452 (delete_catch): Similar, but deleted breakpoints on catch clauses.
4454 Sun Jun 3 22:54:08 1990 Michael Tiemann (tiemann at gzilla)
4456 * blockframe.c (blockvector_for_pc): New function.
4457 * blockframe.c (block_for_pc): Changed to call
4458 `blockvector_for_pc' and get the block itself.
4460 * stack.c (catch_info): New function. Prints info about
4461 exceptions which can be caught in the current frame.
4462 * stack.c (print_frame_label_vars): New function. Similar to
4463 `print_frame_local_vars'.
4464 * stack.c (print_block_frame_labels): Prints out labels that are
4465 defined in this frame. These labels are exceptions that can be
4468 * dbxread.c: Updated to handle N_CATCH symtab types.
4470 Thu May 3 22:10:00 1990 Michael Tiemann (tiemann at teacake)
4472 * valprint.c (everywhere): TYPE_NAME (TYPE) no longer comes in the
4473 form "struct ..." for GNU C++. Don't flush any part of TYPE_NAME
4474 when printing the type.
4476 Wed May 2 22:43:04 1990 Michael Tiemann (tiemann at teacake)
4478 * valprint.c (val_print): Use `baseclass_addr' to access the
4479 baseclasses pointed to via the derived class object at VALADDR.
4481 * values.c (baseclass_addr): New function. Casts derived pointers
4482 to baseclass pointers taking virtual baseclasses and multiple
4483 inheritance into account.
4485 Sat May 5 12:39:18 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
4489 Fri May 4 12:12:55 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
4491 * breakpoint.c (watch_command, bpstat_stop_status): Deal with
4492 exp_valid_block field correctly.
4494 * infrun.c (wait_for_inferior): When checking "don't even think
4495 about breakpoints" if stop_signal == SIGTRAP && trap_expected,
4496 also check step_resume_breakpoint.
4497 Insert breakpoints and continue (not step) if
4498 step_resume_break_address != NULL, even if another_trap.
4499 If trap_expected and we enter sigtramp, then set up a
4501 If trap_expected is set when we hit the step_resume_break,
