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

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

1282 * dbxread.c (read_dbx_symtab): Allow N_SOL to cleanly take us back
1283 to the main file, as well as to include files. Also, put global
1284 functions into the global psymtab, to make "i fun" work.
1285 (end_psymtab): Free named symtabs and psymtabs for a file, once a
1286 new psymtab for it has been read.
1287 * coffread.c (end_psymtab): Free named symtabs and psymtabs for
1288 a file, once a new symtab has been read for it.
1289 * mipsread.c: FIXME. We need to do the same for MIPS, but it
1290 looks harder to determine the top-level block before it's been
1291 queued to the psymtab list.
1293 * symfile.c (symbol_file_add): Use filtered printing and wrap it.
1294 If we have wiped out any old symbol tables, clean up at end of

1298 * symtab.h (GLOBAL_BLOCK, STATIC_BLOCK, FIRST_LOCAL_BLOCK): New
1299 defines for the blocks of a blockvector that contain global and

1309 * symtab.c (list_symbols): Process the first symbol of the
1310 static psymbols list.
1311 (types_info): Restore this function from its untimely #if 0.
1312 It's not perfect, but it is better than nothing.

1328 * symfile.h: free_named_symtab now returns an int.
1330 Mon Apr 8 23:57:43 1991 John Gilmore (gnu at cygint.cygnus.com)
1332 * dbxread.c (dbx_symfile_read): Initialize psymbol list if this
1333 is the first symbol read, even if not mainline.
1334 (dbx_psymtab_to_symtab): symfile might be zero, cope.
1335 * exec.c (exec_ops): Add_syms_addr is valid in our tvec.
1336 (set_section_command): New command ("section xxx yyy" -- should
1337 be renamed to "set section xxx yyy" FIXME) which sets the
1338 base address of a section of the exec file, overriding the
1339 virtual address that BFD reports.
1341 Fri Apr 5 17:14:39 1991 John Gilmore (gnu at cygint.cygnus.com)
1343 * exec.c: Add add_syms_addr_command to exec_ops, so you can

1348 * tm-i386v.h (FLOAT_INFO): Don't define it, since the code
1349 for printing the float info is host-dependent, not
1350 target-dependent. FIXME.
1351 * i386-pinsn.c: Move #includes to top, remove useless ones.
1352 * i386-tdep.c: Don't bother including <.../reg.h> since we
1353 don't use it (and it doesn't exist on host systems).
1355 * ieee-float.c (ieee_extended_to_double): Convert NaN to Inf.
1356 Convert negative numbers properly.
1357 (ieee_test): Make numbers really random; fix format arg.
1359 * infcmd.c (attach_command, detach_command): Don't repeat on CR.
1360 * core.c (core_detach): Unpush core_ops, which might not be on
1361 top. We used to just pop the top, which broke things. Don't
1362 need dont_repeat() any more.
1363 (core_file_command): Psst! Don't repeat it.
1364 * remote-nindy.c (nindy_detach): Don't need dont_repeat() now.
1365 * expprint.c (print_subexp): Avoid switch fallthru on
1366 BINOP_ASSIGN_MODIFY, so we can print += and such.
1367 * frame.h: Fix typo.
1368 * inflow.c (kill_command): After killing inferior, print our
1369 current frame in the core file, if we have one.
1370 (generic_mourn_inferior): When inferior dies, either select
1371 the current frame (in the new target, e.g. core file), or
1372 set both the current and selected frames to NULL.
1374 Changes from Peter Schauer.
1376 * infptrace.c: Avoid <sys/ptrace.h> on USG.
1378 * Make all file names fit in 14 characters (sigh and damn!):
1379 mv hp300hpux-xdep.c hp300ux-xdep.c
1380 mv symmetry-xdep.c symm-xdep.c
1381 mv symmetry-tdep.c symm-tdep.c
1382 mv convex-opcode.h convx-opcode.h
1383 mv tm-vxworks960.h tm-vx960.h
1384 mv tm-vxworks68.h tm-vx68.h
1385 mv Makefile.srcdir Makefile.sdir
1386 mv gdb-int.texinfo gdbint.texinfo
1387 mv remote-sa.m68k.shar rem-m68k.shar
1388 mv remote-multi.shar rem-multi.shar
1389 * Makefile.dist, README, config.gdb, convex-pinsn.c,
1390 tconfig/symmetry, tconfig/vxworks960, tconfig/vxworks68,
1391 xconfig/hp300hpux, xconfig/symmetry: Change names to shorter
1394 * command.c (user_info_1, user_info): New command for listing
1395 the user-defined commands.
1397 Wed Apr 3 15:00:26 1991 John Gilmore (gnu at cygint.cygnus.com)
1399 * dbxread.c (really_free_pendings): Clear file_symbols
1400 and global_symbols after freeing them; otherwise, running
1401 this function twice (if it appears twice on the cleanup
1402 chain), we try to free things twice.
1404 * dbxread.c (read_dbx_symtab): Calculate end_of_text_addr
1405 based on text_addr (the address of text in core), not on addr (the
1406 offset between text in the .o file and in core). This change
1407 is from Peter Schauer.
1409 * main.c: Define ALL_CLEANUPS as a cast of zero.
1410 (return_to_top_level): Use it.
1411 (main): Do all cleanups after each command run as part
1412 of the gdb startup sequence. Also do all cleanups before
1413 entering the command loop, and every time we exit the command
1414 loop and reenter. Before, the cleanups from the startup sequence
1415 were being left undone until the first error!
1416 (command_loop): Rename do_nothing cleanup to command_loop_marker
1417 so we can see it easily when examining the cleanup chain.
1418 (init_signals): Add another do_nothing for signal handling.
1419 (quit_command): Only try to kill target if it has execution.
1420 Problems in the target stack got us into a state where
1421 inferior_pid was nonzero but none of the targets had execution.
1422 In this state you couldn't exit gdb.
1424 * dbxread.c: Two changes from Peter Schauer.
1425 (echo_command): Fflush output after an echo command.
1426 (show_history): Pass all args to cmd_show_list.
1428 * utils.c (init_malloc): Call mtrace to turn on tracing
1429 if the environment variable MALLOC_TRACE is set to a file name.
1430 * mtrace.c: Add source file which provides a log of every malloc,
1431 free, and realloc to a trace file.
1432 * mtrace.awk: Add source file which analyzes the trace file.
1433 * Makefile.dist (GNU_MALLOC, MALLOCSRC): Add mtrace.{c,o,awk}.
1434 (VERSION): Roll to 3.94.3.
1436 * breakpoint.c (breakpoint_1): Add a space to "i watch" output.
1437 (check_duplicates): Don't bother with watchpoints.
1438 (set_raw_breakpoint): Comment about danger of this routine.
1439 (watch_command): Parse and eval all args before calling
1442 * solib.c (find_solib): Avoid error in referencing memory to
1443 see if any more shared libraries have been added. This is
1444 particularly useful if the target has terminated. Bug reported
1447 Changes from Peter Schauer <pesrem@regent.e-technik.tu-muenchen.de>
1448 in bringing up 3.94.2 on the Sun-3.
1450 * Makefile.dist: Include CFLAGS in rule for cplus-dem.o.
1451 * breakpoint.c (enable_breakpoint): Check for valid watchpoint
1452 expression (in scope) before reenabling watchpoint.
1453 * signame.c (init_sigs): Add missing declaration of i, fix
1454 sys_siglist declaration.
1455 * source.c (list_command): Fixed range computation to use
1457 * stack.c (backtrace_command): Do not allow command if target has
1458 no stack, print informative error message.
1459 * target.c (target_command): Do not write into command line
1460 because this fails if the target command is used in a user defined
1461 command. [This change was enhanced by gnu to support any-
1462 unique-prefix matching on target names.]
1463 * valops.c (value_struct_elt): Avoid infinite loop on an
1464 erroneous attempt to print the member of function (try p main.p).
1466 Mon Apr 1 17:05:45 1991 John Gilmore (gnu at cygint.cygnus.com)
1468 * expread.y (name_no_typename): Avoid reduce/reduce errors
1469 caused by ambiguity in handling NAME_OR_INT and NAME_OR_UINT.
1470 Since the GDB parser really doesn't use name_no_typename in a
1471 name-only context, the parser can't tell the diff between
1472 names and numbers here. Avoid allowing a name_no_typename
1473 to be a NAME_OR_*INT to resolve the conflict.
1475 Sun Mar 31 20:12:07 1991 John Gilmore (gnu at cygint.cygnus.com)
1477 Bugfixes from Mark Fox (markf@wrs.com) (test=testField.c):
1479 * valprint.c (val_print_fields): bitfield printing didn't handle
1480 byte order. Indirect through a few more fns to cope.
1482 * values.c (modify_field): also cope with byte order.
1484 Sat Mar 23 10:02:21 1991 John Gilmore (gnu at cygint.cygnus.com)
1486 Cleanup for release 3.94.2:
1488 * Makefile.dist: Pull REMOTE_OBS. Fix saber includes for BFD
1489 include files. Roll version to 3.94.2.
1491 * coffread.c (init_stringtab): Read length into unsigned char
1492 array before swapping; don't assume 32-bit longs.
1494 * target.c (target_info): Don't bother with get_sym_file, just use
1495 the symfile global variable.
1496 * symtab.h, symfile.c (get_sym_file): Delete it.
1498 * dbxread.c (dbx_symfile_init): Don't depend on long == 4 bytes.
1499 (define_symbol): Set symbol line number to 0 if not gcc-compiled.
1500 (read_type): Replace one more error() with complain().
1502 * mipsread.c (parse_partial_symbols): Replace printf with complain.
1504 * i960-tdep.c: Fix copyright attribution.
1506 * config.gdb: Quote all backquotes in doublequotes. You can
1507 quote me on that. BSD 4.4 shell found this one.
1509 * infptrace.c (throughout): The third argument to ptrace is an
1512 * infrun.c (wait_for_inferior): When program has terminated, we
1513 have to call target_terminal_ours before we pop that target off
1514 the stack (e.g. before a call to target_kill or
1515 target_mourn_inferior). This fixes problem where a program
1516 terminates, then GDB stops for (tty output) and you have to type
1517 "fg" to the shell to resume it. FIXME: This code for what to
1518 do after termination really should be in normal_stop instead.
1520 * gdbcore.h (read_memory_check): Change declaration; it changed
1523 * terminal.h: Include <sgtty.h> before <sys/ioctl.h>, since in BSD
1524 4.4 prereleases, this avoids a bug in their sgtty compatability
1526 * remote.c: Use terminal.h rather than hand-rolling the same.
1528 * signame.c, signame.h (psignal): Arg is unsigned, not int.
1529 * utils.c (strsave, strstr): Fix arg types.
1530 * valprint.c (val_print): lint
1532 MIPS symbol table support from Per Bothner:
1534 * symfile.c (symtab_fns): Remove initializer table that needs to
1535 be hacked for each new symbol file format supported.
1536 (add_symtab_fns): New function, chains symbol table
1537 handlers into the global list.
1538 (symfile_init): Search this list.
1539 * symfile.h: Add next pointer, declare add_symtab_fns.
1540 * coffread.c (_initialize_coffread): Call add_symtab_fns.
1541 * dbxread.c (_initialize_dbxread): Call add_symtab_fns.
1543 * mipsread.c (psymtab_to_symtab_1): return void instead of (struct
1544 symbol *). Thus, we no longer need the hack to trash
1545 pst->filename. Good, since that hack confused code in symfile.c!
1547 (reorder_symtabs, destroy_all_symtabs): Removed static
1548 all_symtabs, which was used to qsort symtabs in reorder_symtabs.
1549 Instead, the latter now uses a temporary array (stack-allocated
1550 from an obstack, and then freed).
1552 (parse_symbol): Added a hack to fix up BLOCK_{START,END} if they
1553 haven't been set in the outermost stBlock of a procedure. This was
1554 a problem with f77 binaries on Ultrix 4.?.
1556 (new_symtab, new_symbol, new_type): Continue changing code to use
1557 obstacks more and otherwise conform to dbxread internal style.
1558 Made the free_code of symtabs be free_linetable (as in dbxread)
1559 instead of free_contents. This implies memory leaks when reading
1560 a new symbol table, until the conversion is finished. Did change
1561 (struct symbol) and (struct type) to be allocated on the
1562 symbol_obstack. Blocks and blockvectors are among the things
1565 * mipsread.c (parse_partial_symbols, parse_fdr): It hasn't been
1566 tested much, but it solved one problem (reported by Meissner), and
1567 cleans up some other things. The problem happened when an
1568 included file contains actual code (functions) and not just
1569 definitions. The mips coff is a little inconvenient there, since
1570 it may cause a procedure to be mapped to the wrong psymtab.
1572 * mips-tdep.c (heuristic_proc_desc): Minor cleanup.
1573 * mips-xdep.c (fetch_core_registers): Minor cleanup. FIXME,
1574 this will need work for the new core paradigm.
1576 Opcode patches from the net:
1578 * mips-opcode.h: fix incorrect disassembly of the mfc1, cfc1, and
1579 ctc1 instructions. Also, the cvt.d.w and cvt.s.w instructions were
1580 missing altogether - they are added here. From Bruce Bauman.
1581 * mips-opcode.h: The low mask for C0 instructions was too small.
1582 From Garrett Lau. I modified the fix to check the entire 32-bit
1585 * ns32k-opcode.h: Fix opcodes for deiw and deid. From Bruce
1588 Thu Mar 21 12:56:46 1991 John Gilmore (gnu at cygint.cygnus.com)
1590 Roll in changes from Per Bothner (Tue, 25 Sep 90 11:11:04):
1592 * dbxread.c (read_type): Pointer subtraction (value_sub in
1593 valarith.c) sometimes failed because the types of the
1594 pointers being subtracted were not identical.
1595 These differed because dbxread.c was allocating pointer types
1596 using dbx_alloc_type+smash_to_pointer_type instead of
1597 lookup_pointer_type. I failed to find a justification for the
1598 former, so I changed it to use the latter. Similarly, I
1599 replaced smash_to_function_type by lookup_function_type,
1600 and smash_to_reference_type by lookup_reference_type.
1602 * mipsread.c (parse_symbol, upgrade_type, parse_procedure,
1603 _initialize_mipsread): corresponding changes.
1605 * symtab.c (smash_to_{pointer,reference,function}_type): eliminate.
1607 * source.c (mod_path): Do tilde_expand on each component of the path,
1608 rather than on the (list of) paths as a whole.
1609 (print_source_lines): Set first_line_listed in addition to
1610 current_source_symtab and current_source_line. If the source was
1611 not findable, after a "dir" command to fix the problem,
1612 a "list" would get the wrong lines.
1614 While I was there... (gnu):
1616 * dbxread.c (read_type): Change error to complaint.
1618 Thu Mar 21 12:56:46 1991 John Gilmore (gnu at cygint.cygnus.com)
1620 First attempt at detailed understanding of symbol table memory alloc.
1622 * dbxread.c (dbx_symfile_read): Free our string table if we
1623 aren't the mainline. Free the "info" struct since we're done with
1625 (init_psymbol_list): Free any previously allocated psymbol lists.
1626 (): FIXME: Should realloc-down the psymbol lists when done reading
1627 the main symbol file?
1629 * symmisc.c (free_symtab): Free fullname field too.
1631 * xm-hp300hpux.h (USG): #undef then #define so Makefile can -D.
1632 (REGISTER_ADDR): Make result type unsigned int.
1634 * xconfig/{i386*,hp300hpux,altosgas,altos}: All config files that
1635 define REGEX must also define REGEX1 (its dependency).
1637 Tue Mar 19 21:28:57 1991 John Gilmore (gnu at cygint.cygnus.com)
1639 * tconfig/i960: No longer works, points you at vxworks960 or
1642 * xgdb.c, XGDB-README: Remove file. Users can get the much
1644 * Makefile.dist: Remove all trace of xgdb.
1646 * breakpoint.c (breakpoint_1): Pass demangle arg to
1647 print_address_symbolic.
1648 (clear_breakpoints): Remove unused function.
1649 (breakpoint_re_set_one): Guts of breakpoint_re_set.
1650 (breakpoint_re_set): Use catch_errors to do them all anyway.
1652 * gdb-int.texinfo (Host versus Target): Add section on what is
1653 a "host" feature versus what is a "target" feature.
1655 * infcmd.c (path_command, path_info): Handle the PATH variable
1656 (object search path) as conveniently as the source search path.
1657 * environ.c (set_in_environ): Set some vars in GDB's environment,
1658 in addition to the child's. PATH, G960BASE, G960BIN for starters.
1659 * source.c (mod_path): New function, from guts of
1660 directory_command, modifies a path. Used by path_command.
1661 (directory_command): Call it.
1662 * defs.h (strsave): Declare.
1664 * utils.c (sevenbit_strings): Add new printing option.
1665 (printchar): Use it.
1666 (strsave): Provide this handy helper routine.
1667 (set_width_command): Rename set_screen_width_command.
1668 (_initialize_utils): "set screen-width" => "set width";
1669 "set screen-height" => "set height"; add sevenbit-strings.
1671 * infcmd.c (do_registers_info): Print floating point registers
1672 in raw hex as well as float format, regardless of whether it is
1673 a "virtual" convertible register.
1674 * tm-sparc.h (PRINT_REGISTER_HOOK): Print every pair of float
1675 regs as a double, just in case it's being used that way.
1676 * values.c (unpack_long): Comment on array/function coercion.
1677 (unpack_double): Argument is in target byte order now. For
1678 integer arguments, just call unpack_long and float the result.
1679 * m68k-tdep.c: include defs.h for "const" handling.
1680 * remote-nindy.c: Use ieee-float stuff.
1681 (nindy_fetch_registers): Unpack double regs to host double, then
1683 (nindy_store_registers): Pack extendeds to host double, flip
1684 around by misusing unpack_double, send as target double.
1686 * tm-vxworks68.h (FRAME_CHAIN): Handle current frame pointer of
1687 zero, as when stopped at the first instruction of a process.
1689 * blockframe.c: Fix filename in comment (param.h => tm.h).
1690 * sparc-tdep.c (skip_prologue): More explicit nudging comments.
1691 * tm-68k.h: Fix typos.
1693 Fri Mar 15 01:09:34 1991 John Gilmore (gnu at cygint.cygnus.com)
1695 Changes from a bringup on the DEC Vax under Ultrix 4.0.
1697 * coredep.c (fetch_core_registers): Pass end-address of register
1698 section to register_addr as expected. Don't call supply_register
1699 if we'd just pass it garbage.
1701 * dbxread.c (read_dbx_symtab): Skip N_NSYMS on Ultrix.
1703 * exec.c (xfer_memory): Use boolean xfer_fn result, not int.
1705 * target.c (push_target, target_info): Cast enums to int for < or
1708 * stack.c (print_frame_info): Identify source file & line
1709 even if we can't print it.
1711 * xm-vax.h (MISSING_VPRINTF): No longer missing in Ultrix V4.0.
1713 Sat Mar 9 10:08:20 1991 John Gilmore (gnu at cygint.cygnus.com)
1715 Clean up IEEE floating point support.
1717 * ieee-float.h: New file.
1718 * ieee-float.c: Write real routines to convert between host
1719 doubles and various target IEEE extendeds.
1720 * m68k-xdep.c: Eliminate assembler code for extended floats.
1721 * xconfig/{3b1,altos,altosgas,hp300bsd,isi,news,news1000,sun2os3,
1722 sun2os4,sun3,sun3os3,sun3os4}: Eliminate use of m68k-xdep.o.
1723 * tm-i960.h, tm-68k.h (REGISTER_CONVERT_TO_VIRTUAL,
1724 REGISTER_CONVERT_TO_RAW): Use ieee_extended_to_double and
1725 double_to_ieee_extended.
1726 * i960-tdep.c: Define ext_format_i960.
1727 * m68k-tdep.c: Define ext_format_68881.
1728 * sparc-tdep.c: Define ext_format_sparc, though unused.
1729 * Makefile.dist (HFILES): Add ieee-float.h.
1730 * inftarg.c: #include "ieee-float.h" for the REGISTER_CONVERT
1733 Obsolete the "coffstrip" program in favor of using BFD's strip.
1735 * nindy-share/coffstrip.c: Remove file.
1736 * nindy-share/nindy.c (coffstrip): Routine to run bfd_strip.
1737 * Makefile.dist: Remove references to nindy-share/coffstrip.c.
1738 * tconfig/nindy960: Remove reference to coffstrip.o.
1740 * Makefile.dist: Roll version number to 3.94.1 (not yet final).
1742 Wed Mar 6 09:56:45 1991 John Gilmore (gnu at cygint.cygnus.com)
1744 * symfile.h: Add symfile_bfd, common between dbxread and coffread.
1745 * dbxread.c: Remove static symfile_bfd.
1746 * infcmd.c (do_registers_info): Add PRINT_REGISTER_HOOK, though
1748 * inftarg.c (child_detach): Pop the child_ops vector if the
1749 detach is successful.
1750 * remote-nindy.c (nindy_create_inferior): Don't push a new
1751 nindy_ops since nindy uses the same one for execution and memory
1753 * core.c (core_ops): Use child_attach and child_create_inferior
1754 rather than default attach and create_inferior functions.
1756 Handle floating point registers in core files.
1758 * sparc-xdep.c (fetch_core_registers): Rewrite for float support.
1759 * sun3-xdep.c (fetch_core_registers): Rewrite for float support.
1760 This version untested since BFD doesn't yet support sun3 core
1762 * hp300hpux-xdep.c: Rewrite fetch_core_registers to new calling
1763 conventions. Fix comments and style. This version has not
1764 been compiled yet, since we have no HP inhouse.
1765 * core.c (get_core_registers): Look for two sections, ".reg"
1766 and ".reg2", and pass both to fetch_core_registers sequentially.
1768 Revise directory path yet again.
1770 * source.c (forget_cached_source_info): Not static any more.
1771 (init_source_path): New default source path is "$cdir:$cwd".
1772 (dir_command): Handle variable arguments ($cdir, $cwd).
1773 (source_info): Print "Compilation directory" rather than
1774 "Originally compiled in" to remind people of $cdir.
1775 (openp): If the path contains $cwd, use current directory.
1776 (open_source_file): If compilation directory is known, replace
1777 first $cdir in path with the compilation directory.
1778 (print_source_lines): Even if we can't print the lines, set the
1779 current symtab and line for future commands like "info source" or
1780 "breakpoint". Also, error message now contains the file name,
1781 line number, and file access error message.
1782 (_initialize_source): Fix help text to describe changes.
1783 * main.c (cd_command): Forget cached source info when we chdir.
1784 * utils.c (strstr): Add simple implementation.
1786 Tue Mar 5 01:41:40 1991 John Gilmore (gnu at fowanton.cygnus.com)
1788 * coffread.c (read_one_sym, init_linetable, init_stringtab):
1789 Byte-swap COFF symbol tables if necessary when reading them in.
1790 Use complain() to replace error message in one spot. Needs
1791 corresponding change in bfd/coff-code.h to make some symbol
1792 swapping routines non-static.
1794 Mon Mar 4 00:53:40 1991 John Gilmore (gnu at cygint.cygnus.com)
1796 Merge changes from Eirik Fuller, for UTek.
1798 * defs.h (errno): Add declaration.
1799 * altos-xdep.c, arm-xdep.c, convex-xdep.c, gould-xdep.c,
1800 hp300hpux-xdep.c, infrun.c, inflow.c, infptrace.c, i386-tdep.c,
1801 i386-xdep.c, pyr-xdep.c, mips-xdep.c, remote-eb.c, remote-nindy.c,
1802 remote-vx.c, source.c, standalone.c, stuff.c, sun386-xdep.c,
1803 symmetry-tdep.c, symmetry-xdep.c, umax-xdep.c, utils.c: Eliminate
1804 declarations of errno.
1806 * remote-eb.c: Define B19200 and B38400 as EXTA and EXTB.
1808 * remote-vx.c: Include <sys/time.h> for UTek; Sun gets it via
1809 <rpc/rpc.h> and <rpc/types.h>.
1811 Sat Mar 2 15:47:55 1991 John Gilmore (gnu at cygint.cygnus.com)
1813 * i960-tdep.c (examine_prologue): Add new argument limit,
1814 which stops the scan at the end of the prologue, or at the PC.
1815 This fixes a problem where it walks down into the code for the
1816 user's statements if that code looks like function prologues.
1817 Mark Fox and I have been bouncing this code back and forth, making
1818 small changes to it. Callers changed to match.
1820 Tue Feb 26 01:47:07 1991 Cygnus John Gilmore (cygnus at yuba)
1822 Cleanup for gdb-3.94 release final:
1824 * Makefile.dist: Remove remote-vx.c, remote-nindy.c, and all
1825 the .c files from vx-share and nindy-share, from the various
1826 macros, since they are not found via ALLDEPFILES.
1827 (SFILES): Add tm-i960.h.
1828 (alldeps.mak rule): Break out ALLDEPFILES_MAINDIR and
1829 ALLDEPFILES_SUBDIR. List all the nindy and vxworks subdir files
1831 (TAGFILES_MAINDIR): Change ALLDEPFILES to ALLDEPFILES_MAINDIR.
1832 (gdb.tar.Z): Use ALLDEPFILES_SUBDIR as well as SFILES_SUBDIR.
1834 Mon Feb 25 16:02:35 1991 Cygnus John Gilmore (cygnus at oldman)
1836 * am29k-tdep.c: Add contribution line.
1837 (examine_prologue): Cache information about function prologues in
1838 the misc-function-vector to avoid lots of references over the
1839 serial line while examining instructions.
1841 * core.c (core_close): New function made from cleanup_core.
1843 * core.c, exec.c, inftarg.c, remote-eb.c, remote-nindy.c,
1844 remote-vx.c, remote.c, target.c, target.h,
1845 Update target_ops vector to add attach, close, and load entries.
1846 Use add_syms_addr_command, not add_file_addr_command, for
1847 add_file. Break out close routine from existing code.
1849 * dbxread.c (really_free_pendings): Don't free pending_blocks;
1850 they are in an obstack.
1851 (read_dbx_symtab): Relocate end_of_text_addr in the psymtab.
1853 (define_symbol): Add symbol type parameter; change callers;
1854 pass type parameter to DBX_PARM_SYMBOL_CLASS macro to allow
1855 it to influence the symbol class on the i960.
1856 (define_symbol): Swap LOC_CONST's into target byte order.
1858 * exec.c (exec_close): New function.
1859 (exec_file_command): Call it.
1861 * findvar.c (read_relative_register_raw_bytes): Doc byte order,
1862 Fix byte order of frame pointer.
1863 (read_var_value): Result of 0 if var's value can't be found,
1864 e.g. missing FRAME_ARGS_ADDRESS. Byte-swap LOC_CONST and
1865 LOC_LABEL values to target order. Add LOC_LOCAL_ARG.
1866 (locate_var_value): Use read_var_value and use its lazy address
1867 as the location of the var's value. Lint.
1869 * i960-pinsn.c (next_insn): Add routine from vxgdb for scanning
1872 * i960-tdep.c (arg_address, i960_frame_find_saved_regs): Remove
1873 obsolete Intel versions in favor of vxgdb versions.
1874 (check_host, byteswap, byteswap_val, reorder_val): Eliminate
1875 code dealing with byte order of values, which Intel did in host byte
1876 order rather than gdb-4's target byte order.
1877 (i960_frame_chain_valid): Move to nindy-tdep.c.
1878 (examine_prologue, skip_prologue, frame_find_saved_regs,
1879 frame_args_address, leafproc_return, saved_pc_after_call,
1880 pop_frame): Add vxgdb versions from Mark Fox.
1881 (examine_prologue, frame_struct_result_address): Add code
1882 to deal with the saved value of G13 (struct return address
1884 (frame_args_address): Modify Mark's version to prefer the
1885 saved value over the current value in the topmost frame.
1886 Cache result in the frame info to avoid performance hair in
1888 (print_fault): Add gdb960 code for printing faults.
1889 (_initialize_i960): Actually call check_host.
1891 * ieee-float.c (ieee_extended_to_double, ieee_double_to_extended):
1892 add stub routines. FIXME, these currently just return zero!
1894 * infcmd.c (program_info): Use PRINT_RANDOM_SIGNAL.
1895 (attach_command): Call target_attach, not target_open, now.
1897 * infrun.c (normal_stop): Make global, not static, for vx_attach.
1898 (child_attach): Rename from child_open.
1899 (wait_for_inferior): Use PRINT_RANDOM_SIGNAL. If stop_pc is zero,
1900 don't confuse it with a zero step_resume_break_address.
1902 * inftarg.c (child_detach): Eliminate inferior_pid test.
1903 (child_files_info): Clean up message a bit.
1904 (child_ops): Use child_attach, not child_open, to attach.
1906 * mem-break.c: #ifdef out the whole file if BREAKPOINT is not
1907 set (e.g. on VxWorks or NINDY). Move read_memory_nobpt from
1908 findvar.c to here, since it depends on the contents of the
1909 shadow_contents of breakpoints, but keep if #if 0 since it is
1912 * nindy-tdep.c: New file, contains nindy_frame_chain_valid, moved
1915 * printcmd.c (address_info): Handle LOC_LOCAL_ARG. Lint.
1916 (ptype_command, display_command): Eliminate have_inferior_p and
1917 have_core_file_p in favor of target_has_stack or
1918 target_has_execution.
1919 (print_frame_args): Handle LOC_LOCAL_ARG. Eliminate duplicate
1920 code for actually finding the values of arguments, though we still
1921 keep track of the maximum stack offset for use in printing unnamed
1922 arguments. Handle missing FRAME_ARGS_ADDRESS.
1924 * remote-nindy.c (i960_print_fault): Move to i960-tdep.c.
1925 (struct nindy_regs): Define registers passed to/from nindy.
1926 (nindy_fetch_registers, nindy_store-registers): Translate between
1927 nindy and GDB formats for the registers.
1928 (dcache_init): Statically allocate the cache, since it was being
1929 allocated by a malloc that was never freed anyway.
1930 (nindy_create_inferior): Error, not core dump, if no exec file.
1931 (nindy_before_main_loop): Use target_load, not target_add_file.
1933 * remote-vx.c (net_load): Specify large timeout for load
1934 requests. Allow user to break out with INTERRUPT.
1935 (net_break): Remove useless code, clean up. Change callers.
1936 (parse-args, skip_white_space, find_white_space): Clean up arg
1937 parsing to cope with quoted strings.
1938 (net_wait, net_quit): Never call error, just return status.
1939 (vx_read_register, vx_write_register): Cleanup status checking.
1940 #ifdef the code based on which CPU we are using (960 or 68k),
1941 FIXME, this should be completely general but it isn't yet.
1942 (vx_xfer_memory, vx_resume): Cleanup status checking.
1943 (vx_run_files_info): Improve message.
1944 (vx_load_command): Renamed from vx_add_file_command. Allow load
1946 (net_ptrace): Remove unused routine.
1947 (vx_wait): Adopt code from vxgdb960 to cope with broken
1948 connections to target machine and prompt to disconnect. Remove
1949 debug printouts. Map some EVENT_'s to SIGnals.
1950 (add_symbol_stub, vx_open): Print names of object files we found,
1951 and "ok" if we read their symbols OK. Clarify output in general.
1952 (vx_attach, vx_detach, vx_kill): Add these commands.
1953 (vx_convert_from_virtual, vx_convert_to_virtual): Simplify.
1954 (vx_run_ops): Turn off all_mem, to avoid spurious msg in the
1955 "info files" output, and create_inferior, since we already have
1958 * stack.c (frame_info): Replace Frame_unknown with 0.
1959 (print_frame_arg_vars): Handle LOC_LOCAL_ARG.
1960 (return_command): Pop until the PC matches as well as the FP,
1961 so it works even if the FP is shared with another function,
1962 as in "frameless" or "leaf" procedures.
1964 * symfile.c (load_command): renamed from add_file_target_command.
1965 (add_syms_addr_command): renamed from add_file_addr_command.
1966 (add_syms_command): Stub to call target_add_syms.
1967 (_initialize_symfile): Change command names and descriptions,
1968 add-file => add-syms, and load from alias to its own command.
1970 * target.c (kill_or_be_killed, maybe_kill_then_attach,
1971 maybe_kill_then_create_inferior): Default for attempts to start
1972 a process, if one is already running, is to ask about killing
1973 it and retry if yes.
1974 (upstack_create_inferior): #if-0 it, strata obsolete it.
1975 (push_target, unpush_target, pop_target): to_close() a target
1976 before unstacking it.
1977 (target_info): Renamed from target_files_info.
1978 (_initialize_targets): Rename "i files" as "i target", accessible
1981 * target.h: Improve comments about the target_ vectored routines.
1983 * tm-i960.h: Remove NINDY-specific stuff to tm-nindy960.h.
1984 Convert commenting style to standard GNU style.
1985 (DBX_PARM_SYMBOL_CLASS): allow LOC_LOCAL_ARG's to be recognized.
1986 (SKIP_PROLOGUE): No longer a no-op.
1987 (SAVED_PC_AFTER_CALL): Now handles leaf procedures.
1988 (*_REGNUM): Sort register numbers.
1989 (REGISTER_BYTES, REGISTER_BYTE, REGISTER_RAW_SIZE,
1990 MAX_REGISTER_RAW_SIZE, REGISTER_CONVERTIBLE,
1991 REGISTER_CONVERT_TO_VIRTUAL, REGISTER_CONVERT_TO_RAW): Float regs
1992 are now 10 byte extendeds, not 8 byte doubles.
1993 (FRAME_CHAIN_VALID): Make this config-dependent, since it differs
1994 for nindy versus vxworks targets. FIXME, this should possibly go
1995 in the target vector.
1996 (EXTRA_FRAME_INFO, INIT_EXTRA_FRAME_INFO): Cache both
1997 frame_saved_regs and arg pointer with each frame.
1998 (FRAMELESS_FUNCTION_INVOCATION): New leafproc support.
1999 (FRAME_ARGS_ADDRESS): Use cached result.
2000 (FRAME_ARGS_ADDRESS_CORRECT): New, avoids g14 guessing.
2001 (FRAME_FIND_SAVED_REGS): Change arg to subsidiary fn.
2002 (PRINT_RAMDON_SIGNAL): Call print_fault.
2003 (POP_FRAME): Now works.
2005 * tm-nindy960.h: Break this off tm-i960.h. NINDY-specific
2006 option parsing and startup; STACK_END_ADDR, FRAME_CHAIN_VALID,
2007 BREAKPOINT, and DECR_PC_AFTER_BREAK are here.
2008 (ADDITIONAL_OPTION_HANDLER): use target_load, not
2011 * tm-vxworks960.h: Break this off tm-i960.h. VxGDB specific
2012 startup; DECR_PC_AFTER_BREAK, and FRAME_CHAIN_VALID are here.
2014 * valarith.c (value_subscripted_rvalue): Avoid handling
2015 floats and doubles specially; it gave alignment errors. Lint.
2017 * valops.c (value_of_variable, value_of_this): Error if unknown
2020 * valprint.c (print_floating): Bcopy rather than pointer-deref,
2021 to avoid alignment problems.
2022 (value_print): Handle unknown value address.
2023 (cplus_val_print): Two args are ignored; remove them. Change caller.
2024 (val_print): Use unpack_long rather than pointer-deref.
2027 (unpack_long, unpack_double): Use bcopy rather than pointer-deref
2028 to avoid alignment problems.
2029 (value_being_returned): Error if return value unknown.
2030 (set_return_value): Add bogosity warning, FIXME. *
2032 * TODO: A woman's work is never done.
2034 * Makefile.dist: Distribute REMOTE_OBS into tconfig files.
2035 Separate INCLUDE_CFLAGS for use with lint. Add LINTFILES.
2036 Add ieee-float.o to OBS.
2037 * tconfig/{nindy960,vxworks68,vxworks960}: Include the desired
2038 REMOTE_OBS remote-interface files in the TDEPFILES and TM_FILE.
2039 * tconfig/i960: FIXME. Half-merge, produce warning if config'd.
2041 Changes to generalize the VxWorks RPC protocol slightly, to handle
2042 i960 as well as 68000.
2044 * vx-share/dbgRpcLib.h (VX_SOURCE_STEP): Add.
2045 * vx-share/reg.h: Produce i960 regs #ifdef I80960
2046 * vx-share/xdr_ptrace.c: Skip FPA registers if 960.
2047 * vx-share/xdr_rdb.h: Add SOURCE_STEP struct and xdr decl.
2048 * vx-share/xdr_rdb.c: Add xdr_SOURCE_STEP routine.
2049 * vx-share/xdr_regs.c: Add xdr_regs, xdr_fp_status, xdr_ext_fp
2050 for i960. Change xdr_vectors to xdr_opaques for 68k registers,
2051 so they will move in target byte order rather than network
2052 byte order (happens to be the same).
2054 Mon Feb 25 03:41:44 1991 John Gilmore (gnu at cygint.cygnus.com)
2056 * tm-convex.h (END_OF_TEXT_DEFAULT): Remove #if 0'd block.
2058 Sun Feb 24 00:55:53 1991 John Gilmore (gnu at cygint.cygnus.com)
2061 Add contribution lines to various files, showing where they
2064 * breakpoint.c (break_insn, check_break_insn_size,
2065 read_memory_nobpt): Remove to mem-break.c.
2067 * xm-*.h, param-no-tm.h, tm-29k.h, valprint.c: Change BYTE_ORDER to
2070 * tm-29k.h (STAB_REG_TO_REGNUM): Warn user if symbol table
2071 entry has bad register number. This change is not
2072 tested in this release, FIXME.
2074 * frame.h: Eliminate Frame_unknown in favor of a simple zero.
2077 * value.h: Force value's contents field to be aligned to hold
2078 at least a double or a long long (if supported). This avoids
2079 doing bcopy's in and out of the contents field.
2081 (step_1): Avoid coredump under obscure circumstances when we
2084 * symtab.h (misc_info): Add field to misc function vector for
2085 any kind of cached information the target code desires. AMD
2086 29000 uses this to avoid repeating examine_function_prologue's.
2088 * coffread.c: Lint. Remove static symfile, read_section_header.
2089 core.c (have_core_file_p): Lint: remove.
2090 expprint.c (print_subexp): Lint.
2091 infptrace.c, valops.c, valprint.c: lint.
2093 Roll in changes from vxgdb-5.0.1:
2095 * symtab.h: Comment byte order of each address class. Add
2096 LOC_LOCAL_ARG for frame-relative args (960).
2097 expread.y: Use LOC_LOCAL_ARG where LOC_ARG is used.
2098 symtab.c, symmisc.c: ditto.
2100 * infrun.c (init_wait_for_inferior): Clear stop_signal.
2102 * remote.c (remote_resume): Error if resume with a signal.
2104 * symfile.c (prim_record_misc_function): Clear misc_info.
2105 (fill_in_vptr_fieldno): Check stub type of arg.
2107 * valops.c (value_cast): Avoid looking up names of types whose
2108 name we don't know, to prevent coredump. Sun CC produces typedef
2109 rtx and the name of *rtx is zero...
2111 Mon Feb 18 21:16:25 1991 John Gilmore (gnu at cygint.cygnus.com)
2113 Roll in changes from final AMD 29000 port (Tiemann).
2115 tconfig/am29k: Add COFF_ENCAPSULATE and TARGET=TARGET_AM29K
2116 for ../include/a.out.encap.h. This might not work now that BFD
2117 is separately compiled. Instead, BFD support for encap will have
2118 to translate machine type 29k into the right COFF_MAGIC.
2120 * infcmd.c: Remove references to inferior_pid that aren't used
2121 in actual ptrace calls; use target_has_execution, etc.
2122 (have_inferior_p): Remove function.
2123 (program_info): Print target info rather than "process number";
2124 avoid gratuitous messages unless from_tty.
2125 (run_stack_dummy, finish_command): Set proceed_to_finish.
2126 infrun.c: Remove inferior_pid refs. Decl & init proceed_to_finish.
2127 main.c: Lint. Lose have_inferior_p().
2128 inferior.h (have_inferior_p): Remove, lint.
2129 (proceed_to_finish): Add flag to ask that all regs be saved
2130 by normal_stop, for the few commands that need it, speeding up
2131 serial I/O. Add comments to stop_registers.
2133 * remote-eb.c: Remove newline from breakpoint message we grep
2134 for. Never time out when running the user program.
2138 Wed Feb 13 15:34:40 1991 John Gilmore (gnu at cygint.cygnus.com)
2140 Roll in changes from vxgdb-5.0.1:
2142 * dbxread.c (read_dbx_symtab): If we encounter a "FORTRAN COMMON"
2143 symbol in its raw form, we are processing an unlinked ".o" file.
2144 See if the target environment has assigned it an address, using
2145 target_lookup_symbol (VxWorks does), and enter it into the symtab
2148 * tm-vxworks.h (FRAME_CHAIN, FRAME_CHAIN_VALID): Override usual
2149 68k versions for a simpler version that assumes zero FP at bottom.
2150 Fixes bug of truncated stack reports.
2152 * target.h (target_lookup_symbol): Define this routine's args
2153 and result, finally.
2155 * target.c (nosymbol): Default routine for target_lookup_symbol.
2156 (target_default): Default lookup_symbol and call_function too.
2157 (files_info): Only print has_all_memory warning if a non-dummy
2160 * remote-vx.c (vx_read_register, vx_convert_to_virtual,
2161 vx_convert_from_virtual): If target does not have floating point,
2162 zero register "values", and avoid doing cross-net conversions.
2163 (vx_lookup_symbol): Rename net_lookup_symbol, add to vectors.
2164 (vx_open): Rearrange code that attaches to target and reads
2165 symbols for all loaded modules, to work if some of the modules
2166 are not accessible. Add symbol_stub() and add_symbol_stub()
2167 as callbacks from catch_errors(). Allow connect attempt to be
2168 interrupted painlessly with ^C (FIXME, there are still some bugs
2169 if the interrupt happens during symbol reading.). Print
2170 final message with puts_filtered, since symbol messages are
2175 * main.c (catch_errors): Only print errstring if non-null.
2176 (command_loop): Avoid an ioctl per command to test ISATTY.
2178 * remote-vx.c (net_load): make static; avoid sophomoric msg.
2179 (vx_xfer_memory): Return correct result!
2180 (vx_files_info): Indicate whether target has float or not.
2181 (vx_lookup_symbol): Complain, not error, if target gone.
2182 (vx_open): Print "Connected" msg before disabling immediate-quit.
2183 [FIXME: lookup_symbol and vx_open changes need testing.]
2185 target.c, remote-eb.c, inftarg.c, am29k-opcode.h, target.h,
2186 tm-29k.h, tmm-vxworks68.h, symfile.c, gdb-int.texinfo: Add
2187 contributor lines and update copyrights to 1991.
2189 Changes from an attempted H-PUX host port:
2191 * infptrace.c (PT_ATTACH, PT_DETACH): Handle HP/UX, which
2192 defines PT_ATTACH and PT_DETACH but not PT_KILL.
2193 * remote-eb.c (eb_open): Misplaced endif kills sysv H/PUX.
2194 * remote-vx.c: include <sys/time.h> for HPUX.
2195 * hp300hpux-xdep.c (fetch_core_registers): Rewrite old
2196 "core_file_command" routine to BFD regime. May not work yet.
2198 Attempted port of "gdb-3.4 Van Jacobson xgdb" to modern gdb.
2200 * xgdb.c: Replace X10 version with some VJ version.
2201 (FIXME: Its copyright assignment is not on record.)
2202 * xgdb.c: Update include files to X11R4 (Xaw crud).
2203 (xgdb_display_source, create_text_widget): fix call to
2204 get_filename_and_charpos. Rewack source window stuff for X11R4
2205 (gleaned from include files, and "nm's" of binary libraries, since
2206 I had no doc available).
2207 (append_selection, append_selection_word): Disable with FIXME
2208 since R4 changed interface here.
2209 (create_buttons): Add back the old set of buttons.
2210 (xgdb_create_window): Fix call to XtInitialize (&argc not argc).
2212 * Makefile.dist (xgdb, xgdb-init.c): Update for X11R4 on Suns.
2213 Roll VERSION to 3.94 (not yet final though).
2215 Sat Feb 9 09:46:25 1991 John Gilmore (gnu at cygint.cygnus.com)
2217 * obstack.h (obstack_ptr_grow, obstack_ptr_grow_fast,
2218 obstack_int_grow, obstack_int_grow_fast): Eliminate
2219 cast on left of assignment, which gives MIPS cc fits and is
2222 * sparc-pinsn.c (print_insn): Eliminate 'set' test, subsumed by
2223 F_ALIAS. Use printf, not fprintf, when not passing a file
2225 (compare_opcodes): Check that identical instructions have
2226 identical opcodes, complain otherwise.
2228 * sparc-opcode.h (st %fsr): Fix opcode "lose" mask. This
2229 was reported by Roland McGrath.
2230 (unimp): Only match if exactly zero instruction. (Roland)
2231 (branches and traps): Generate all variations of these
2232 instructions with macros, based on a single call that defines
2233 each condition name and its binary representation.
2234 (set): Turn on alias bit, to avoid test in sparc-pinsn.c.
2236 * valprint.c (val_print_fields): Take, and use, format parameter.
2237 This means that "p/x struct" again prints the elements in the
2238 desired format. Changed callers.
2240 * stack.c (frame_info): Use filtered output, and indicate wrap
2241 points. Remove kludgy formatting designed to avoid line wrap.
2243 * utils.c (wrap_here): If the line is already full (because
2244 we had printed a long indent or long wrapped string), do an
2245 immediate newline-and-indent.
2247 * m68k-pinsn.c (print_insn_arg): Bugfix from
2248 ntmtv!thompson@ames.arc.nasa.gov (Mike Thompson): 'bkpt #0'
2249 instruction is incorrectly disassembled as bkpt #8.
2251 * dbxread.c (end_psymtab): Bugfix from Peter Schauer
2252 <pesrem@regent.e-technik.tu-muenchen.de>: If you want to set a
2253 breakpoint in a *.y file gdb will say Reading in symbols for *.y...
2254 and then will dump core (sometimes). I traced it back to an
2255 uninitialized symfile_name in psymtab_to_symtab.
2256 (const_vol_complaint): Add quotes to message.
2257 (define_symbol): Only believe line number if gcc_compiled.
2258 Avoid allocating symbol if we will not return it.
2260 Add target strata support so that newly established targets go
2261 into their right place in the target stack (e.g. a new exec file
2262 doesn't wipe out the ability to access the running process).
2264 * target.h, core.c, exec.c, inftarg.c, remote-eb.c,
2265 remote-nindy.c, remote-vx.c, remote.c, target.c: Add to_stratum
2266 and initialize it properly in all the targets.
2268 * target.h: Document strata. Change return type of push_target.
2270 * target.c (nomemory): new function for dummy memory access.
2271 (tcomplain): Rename complain, now also used in symfile.c.
2272 (push_target): Push targets within strata. New return value shows
2273 whether new target is on top of stack or not. Always keep dummy
2275 (target_files_info): Ignore dummy target.
2277 * core.c (core_open): Warn user, and skip accessing file, if the
2278 core target is not the topmost target in the stack.
2279 * remote-nindy.c (nindy_create_inferior): Avoid unpush_target, now
2282 * remote-vx.c: Remove vx_prepare_to_store from vxworks memory
2283 target_ops, it doesn't belong there since we have no regs there.
2284 Change name of target from machine => memory to clarify.
2286 Thu Feb 7 16:32:09 1991 John Gilmore (gnu at spiff.cygnus.com)
2288 * Freeze version 3.93 for release.
2290 * Makefile.dist: Handle vx-share and nindy-share subdirs
2291 properly when building gdb.tar.Z.
2293 * symtab.c: lint; add no_symtab_msg to consolidate the messages
2294 printed in various places, so I could change just one copy.
2296 * dbxread.c, coffread.c: Change references to bfd->iostream
2297 to cast to FILE *, now that BFD avoids needing types defined
2298 in other header files.
2300 Tue Feb 5 21:39:35 1991 John Gilmore (gnu at cygint.cygnus.com)
2302 * command.c, dbxread.c, expprint.c, infcmd.c, infptrace.c,
2303 infrun.c, printcmd.c, remote-nindy.c, source.c, sparc-tdep.c,
2304 sparc-xdep.c, symfile.h, symmisc.c, utils.c, valprint.c: Lint
2305 (actually gcc -Wall).
2307 * dbxread.c: Remove first_global_sym, last_global_sym, since
2308 they are never referenced.
2310 * defs.h (baud_rate): Declare.
2311 main.c: Define it, and add the -b option to set it.
2313 * gdb-int.texinfo: Add text on how to define a new host or target
2314 architecture, prompted by Per Bothner's questions about MIPS
2317 * gdb.texinfo: Document "complaints". Change doc of -q since
2318 gdb no longer prints the copyright and blurb if you specify a file
2319 name to be debugged (just like Emacs). Add doc for Nindy-specific
2320 command line flags for specifying target serial port and such.
2321 Update copyright to 1991.
2323 * gdbcore.h: Remove a large mass of now-useless crud, since BFD
2324 has taken over for us the job of ripping up executable files. The
2325 crud caused Per Bothner's port to not compile.
2327 * infrun.c (normal_stop): Avoid printing "Program exited
2328 normally" if we are in batch mode. This allows a GDB which
2329 executes a program on a target system, to behave like a Unix
2330 command (input from stdin, output to stdout, no extraneous
2333 * main.c (main): Allow additional machine-dependent command line
2334 options to be specified with the ADDITIONAL_OPTIONS,
2335 ADDITIONAL_OPTION_CASES, ADDITIONAL_OPTION_HELP, and
2336 ADDITIONAL_OPTION_HANDLER macros. Also allow machine-dependent
2337 processing to occur just before the main loop with
2338 BEFORE_MAIN_LOOP_HOOK.
2339 (main): If a "core file" argument is specified, and it is not a
2340 core file, try it as a process ID to attach.
2341 (symbol_completion_function): Attempt to cope with
2342 "show screen-" TAB, not very successfully. This needs more work,
2344 (batch_file): New function, returns whether we are reading
2345 commands from an interactive tty on stdin, or from somewhere else.
2346 Called by normal_stop since it doesn't get from_tty passed down
2347 to it like many commands do.
2349 * remote-nindy.c: Handle command line options for nindy
2351 (nindy_before_main_loop): Prompt user for tty name if they
2352 don't specify it before getting to the interactive command loop.
2354 * tm-i960.c: Add ADDITIONAL_OPTIONS, etc, to handle -O, -brk,
2355 and -r command line options. Also add hook before main loop
2356 to make it easy to specify a tty.
2358 * TODO: More things to do, one done.
2360 Mon Feb 4 23:57:39 1991 John Gilmore and Mike Tiemann (at cygint.cygnus.com)
2362 * dbxread.c: Make complaint() calls pass pointer, not struct.
2363 Add complaints about badly formatted C++ type information
2364 (const/volatile indicator, and parse errors resulting in
2365 error_type). Fix C++ virtual member fn comment.
2366 (read_struct_type): Avoid bumping pointer if we got a parse
2367 error; this prevents our walking beyond the end of a string.
2368 Terminate loop on null char as well as semicolon.
2369 (process_one_symbol): Fix the LBRAC fix so that it uses the
2370 last previous SLINE, FUN, or SO record's PC address. C++ debug
2371 symbols did not have SLINE records in a useful order compared
2372 to the LBRAC records.
2373 (define_symbol): Handle "catch" records.
2375 * symtab.c (check_stub_type): Added new complain
2376 `stub_noname_complain' and added a consistency check to
2377 keep the debugger from crashing when finishing from an
2378 exception frame. A real fix will be needed later.
2380 Sat Feb 2 10:43:05 1991 John Gilmore (gnu at cygint.cygnus.com)
2382 * infcmd.c (attach_command): Make global.
2384 * Makefile.dist (REMOTE_OBS): Make these compile by default,
2385 but make them easy to comment out. Perhaps later they should
2386 be enabled by what CPU you configure for? FIXME.
2387 (VERSION): Roll to 3.93.
2388 (pinsn.o): Remove rule for obsolete file.
2389 (dbxread.o,coffread.o,mipsread.o): Use ${srcdir} explicitly.
2391 Run down a problem that manifested by printing the wrong function
2392 name in stack traces of read_ofile_symtab. Turned out that the
2393 problem was the SunOS 4.1.1 (and previous) C compiler outputs
2394 the LBRAC symbol with an address in the *data* segment, which
2395 blew our binary search through the blocks.
2397 * dbxread.c: Use the complain() facility consistently to bitch
2398 about problems in the symbol file we are reading.
2399 (finish_block): Add code to check the nesting of the blocks;
2400 complain and Procrust them to fit if wrong.
2401 (make_blockvector): Check the order of the blocks, complain
2402 [but don't cope] if wrong.
2403 (process_one_symbol): ifndef SUN_FIXED_LBRAC_BUG, check LBRAC
2404 symbols to be sure their PC value is greater than the last SLINE
2405 (line number) symbol we've seen, complaining and adopting the
2406 SLINE PC value if wrong.
2408 * symfile.h (struct complaint, complaint_root, complain,
2409 clear_complaints): Add.
2410 * symfile.c (complain, complaint_root, clear_complaints): Add
2411 facility to deal with non-fatal complaints and to regularize their
2413 (symbol_file_add): Clear complaint counters to allow new complaints.
2414 (initialize_symfile): Add 'set complaints' and 'show complaints'.
2416 * dbxread.c (dbx_symfile_read): Remember the address and size
2417 of the string table for the main symbol file, so we won't read it
2419 (dbx_psymtab_to_symtab): Fix the check for main symbol file,
2420 to avoid reading the string table yet again. Lint.
2421 (throughout): Improve filtered output, including word wrap.
2422 (read_range_type): Improve Bothner's fix to handle other types too.
2424 * utils.c: Improve line wrap implementation. Handle unlimited
2425 width by making chars_per_line unsigned.
2426 (puts_filtered): New, easy, function.
2428 * defs.h (puts_filtered): add.
2430 * mipsread.c (compare_symbols, sort_symtab): Remove these fns,
2431 call the identical sort_symtab_syms() in symfile.c instead.
2433 * expread.y: Suggest the `file' command rather than `symbol-file'.
2435 * command.h (enum var_types): Add zinteger for seroable
2437 * command.c (do_setshow_command): Handle var_zinteger. Restructure
2438 nested if's into a switch.
2440 * breakpoint.c (bpstat_print): If bpstat "print" flag is not set,
2441 we did not stop because of a breakpoint (it must have been for
2442 some other reason, like a "stepi"), so don't print anything.
2444 * symtab.c: Include <sys/types.h> all the time. Now that BFD
2445 doesn't include <sys/types.h>, old SunOS's require it for
2448 Sat Feb 2 10:39:15 1991 Per Bothner (bothner@cs.wisc.edu)
2450 A test port of gdb-3.92.6 to the Sony NEWS.
2453 Don't normally link in remote- or vx stuff.
2454 Some of it doesn't compile, and it wastes space for 99% of the users.
2455 Remove reference to no-longer-used HAVE_VPRINTF.
2456 Fixed BFD_DEP typo to BFD_DIR.
2458 Fix cast in arg to bfd_h_getlong.
2459 Make char *prefix be const.
2460 Fix how certain range types are mapped into builtin unsigned int types.
2462 Remove 2 #includes. They cause errors (on Sony, at least),
2463 and aren't needed (they wern't in earlier versions).
2465 print_address_symbolic should never demangle labels
2466 (since it prints *assembler-level* labels).
2468 [This was superseded by the change to printcmd below.]
2471 Add some "volatile" return types to avoid warnings.
2472 If MISSING_VPRINTF add vprintf function and not just macro
2473 (since vprintf is used in printcmd.c).
2475 Unless __GNUC__, use obstack_grow instead of obstack_ptr_grow.
2476 (The latter isn't grokked by some PCC-based compilers.)
2478 [This change is in abeyance, we prefer to fix obstack_ptr_grow.]
2480 Make chunk size of dont_print_obstack 32*4 instead of default 4096.
2481 * nindy-share/coffstrip.c
2482 Added some forward declarations (otherwise, gcc complains
2483 about implicit extern redefined as static).
2485 Sun Jan 20 02:38:19 1991 John Gilmore (gnu at cygint.cygnus.com)
2487 Changes inspired by Per Bothner:
2488 * printcmd.c (print_address_symbolic): Take additional parameter
2489 specifying whether to demangle.
2490 (print_address): Pass in asm_demangle to control demangling.
2491 (print_address_demangle): New fn, takes explicit arg to control
2493 * utils.c: Add new vars demangle and asm_demangle, and let them
2495 (fputs_demangled): If !demangle, just print the argument.
2496 (fprint_symbol): If !demangle, just print raw symbol.
2497 * valprint.c (val_print): Call print_address_demangle rather than
2498 print_address, to cause demangling to depend on the global
2499 rather than assembler-level demangling setting.
2500 * WHATS.NEW, gdb.texinfo: Document.
2502 * main.c (show_command): Show all settings if no arg.
2503 (initialize_main): Make "info set" the same as naked "show".
2504 * command.c (cmd_show_list): Handle prefix commands in the
2505 list, and print the name of the setting as well as its English
2506 description and value.
2508 Allow gdb functions to specify where a line should wrap if it
2509 exceeds the size of a terminal line. Use it to make the output
2511 * utils.c (set_screen_width_command): New fn, mallocs a buffer
2512 of the right size when screen width changes.
2513 (set_screensize_command, screensize_info): Remove #if 0'd fns.
2514 (wrap_here): New fn, indicates a point in the output where we
2515 should wrap the line rather than just letting it overflow at a
2517 (fputs_filtered): Implement wrapping.
2518 (n_spaces): New fn, returns a pointer to N spaces.
2519 (print_spaces_filtered): Use n_spaces.
2520 * defs.h (n_spaces): Declare.
2521 * stack.c (print_frame_info): Wrap with 4-space indent after
2522 fn name and before filename and line number.
2523 * printcmd.c (print_frame_args): Wrap with 4-space indent
2524 before each argument name is printed.
2525 * valprint.c (value_print): Wrap with no indentation before
2527 (val_print_fields): Wrap with indentation relative to nesting
2528 level before each field name.
2529 (val_print): Wrap with nesting indentation before array elements.
2530 * command.c (do_setshow_command): Avoid extra newlines,
2531 wrap with 4-space indent around values printed, end with period.
2532 * WHATS.NEW, gdb.texinfo, gdb-int.texinfo: Document.
2534 * breakpoint.c (breakpoint_1): Implement addressprint for
2535 "info breakpoints" display. Change file name and line number
2536 format to " at file:nnn" rather than " (file line nnn)".
2537 * gdb.texinfo: Document.
2540 Fri Jan 18 07:21:25 1991 John Gilmore (gnu at cygint.cygnus.com)
2542 Frozen for gdb-3.92.6 release.
2544 README, WHATS.NEW: Update for 3.92.6 release.
2546 tconfig/{altos, i386v, i386v32, m88k, umax}: Eliminate
2547 coffread.o from configs since it is now built by default.
2548 tconfig/{3b1, altosgas, arm, convex, hp300bsd, hp300hpux,
2549 i386v-g, i386v32-g, isi, merlin, news, news1000, np1, pn,
2550 pyramid, symmetry, vax, vxworks68}: Eliminate dbxread.o
2551 from configs since it is now built by default.
2553 Makefile.dist: Update for release 3.92.6. Handle files that
2554 have been moved to ../include, ../getopt, or ../bfd. Add
2555 saber.suppress and tests directory. Add config.status to
2556 the release (it will say "none").
2558 coredep.c: Minor formatting fixes.
2560 These changes were made in early December but only checked in now:
2561 * nindy-share/Onindy.c, nindy-share/coffstrip.c,
2562 nindy-share/nindy.c: lint
2563 * nindy-share/nindy.c (ninStopWhy): Don't byteswap the
2564 register values coming back from the target; we store values
2565 in target byte order everywhere.
2567 Wed Jan 16 19:01:37 1991 John Gilmore (gnu at cygint.cygnus.com)
2569 * am29k-opcode.h, am29k-pinsn.c: Add 29050 opcodes.
2571 * valprint.c (cplus_val_print, val_print_fields): New functions,
2572 which print C++ objects. They conspire to avoid printing a
2573 virtual base class more than once, following all the twists and
2574 turns of C++ virtual base rules.
2575 (val_print): Call the above rather than do it by hand.
2577 * symfile.c (symbol_file_add): Only reset symfile_mtime for main
2578 symbol file, not for added files like shared libs. This really
2579 needs to be generalized to a timestamp per file.
2581 * core.c (cleanup_core): Avoid coredump if no core file.
2583 * config.gdb: Accept -host or -target in place of +host or
2586 * coffread.c (find_linenos): Avoid desupported BFD interface
2587 to line numbers. We still read them manually rather than using
2588 BFD's "generic" features.
2590 * gdbrc.tex, threecol.tex: Add GDB reference card and its
2592 Makefile.dist: Add refcard to OTHERS list for creating tar files.
2594 * Makefile.dist: Eliminate use of $< in explicit targets.
2596 * readline/Makefile: Use $< rather than $*.c, which does not
2597 include the VPATH in GNU Make.
2599 * tconfig/i960-bout, tconfig/i960-coff: These are identical
2600 copies of tconfig/i960, added for global configuration
2601 compatability. All i960 versions can read both coff and b.out.
2603 * tm-88k.h: Fix multiline macro that lacked \'s. Remove
2604 COFF_FORMAT and COFF_CHECK_X_ZEROES since these are now handled
2607 * TODO: Think of more things to do.
2609 Wed Jan 2 19:09:29 1991 John Gilmore (gnu at spiff.cygnus.com)
2611 tconfig/{am29k,i960,sun2*,sun3*,sun4*}: Eliminate config
2612 of sdb versus dbx debug symbols. Add kludge for 68881 80-bit to
2613 64-bit float conversion.
2615 tconfig/sun4, tconfig/sun3, xconfig/sun4, xconfig/sun3: Make
2616 equivalent to sun?os4 so global config works.
2618 Wed Jan 2 18:20:51 1991 John Gilmore (gnu at spiff.cygnus.com)
2620 Fix from Eberhard Mattes <mattes@azu.informatik.uni-stuttgart.de>
2622 * main.c: Only declare linesize once; declare pagesize not at
2623 all, since it is never used.
2624 (main): Clear newly allocated line before it is used.
2626 Fri Dec 28 00:13:42 1990 John Gilmore (gnu at cygint)
2628 Further stabilization for the Intel 960.
2630 * Makefile.dist: Parameterize the location of the "include"
2631 and "bfd" directories, as well as "getopt". Add symfile.c.
2632 Link in both dbxread and coffread. Fix up "make depend" to
2633 rewack the locations of include, bfd, and getopt in its output.
2635 * README: Document moving include files, improve some of
2638 * coffread.c: Move common code out to symfile.c. Change
2639 symbol_file_command style interface to use new *_symfile_init
2640 and *_symfile_read interface under BFD. Use BFD internal
2641 info to locate line table, symbols, etc.
2643 * core.c (core_fetch_registers): Rename to get_core_registers
2644 to avoid confusion with fetch_core_registers.
2645 (register_addr): Move to coredep.c, which is already machine
2646 dependent. This leaves core.c pretty clean of dependencies.
2648 * coredep.c (register_addr): Accept this routine from core.c.
2650 * dbxread.c: Move common code (with coffread.c, etc) into new
2651 symfile.c. Each psymtab now contains a pointer to the
2652 format-dependent function that knows how to read it in. Make
2654 (dbx_psymtab_to_symtab): Renamed from psymtab_to_symtab_2.
2655 (process_one_symbol): Add code to complain about a "compiler bug
2656 we muzzle here", if we actually see it.
2658 * eval.c (evaluate_subexp): Insert missing "break" statements
2659 in code that determines whether a variable is an lvalue in
2660 memory, register, or whatever. I detected this via a compiler
2661 bug in which it *almost* mashed out the whole switch statement.
2663 * gdb-int.texinfo: Add minor sections on configuring gdb for
2664 release, and about the README file.
2666 * infcmd.c (registers_info): Fix formatting somewhat. Still
2667 not as pretty as before, but it handles byte swapping.
2669 * remote-nindy.c: If data cache routines are interrupted while
2670 waiting for the remote end, be sure that any uninitialized cache
2671 blocks are on the free list, not on the valid list!
2673 * symfile.h: Flesh out this header file with all the various
2674 routines and variables that have been merged in from dbxread.c
2675 coffread.c, and symtab.c to symfile.c.
2677 * symfile.c: New file, containing code common to dbxread.c,
2678 coffread.c, and some code from symtab.c. All generic code for
2679 reading symbol files should be in here now.
2680 (unrecord_misc_function): Remove unused function.
2682 * symtab.h: Remove file-reading things to symfile.h.
2684 * symtab.c: Remove file-reading things to symfile.c.
2686 * tm-i960.h: Fix FRAME_CHAIN types; define PRINT_RANDOM_SIGNAL
2687 to decode i960 fault types.
2689 * target.h, remote.c, remote-eb.c, remote-vx.c, remote-nindy.c,
2690 target.c: Change type of the "resume" function from int to void,
2691 since its result was never used.
2693 Sat Dec 22 02:51:40 1990 John Gilmore (gnu at cygint)
2695 * main.c: Replace "stupid" with "caution"; you now "set caution
2698 * printcmd.c (print_scalar_formatted): Fix typo in 'g' format
2700 * infcmd.c (do_registers_info): Call val_print to deal with the
2701 byte order of the registers being printed. FIXME, this makes
2702 the formatting of the output uglier.
2704 * infcmd.c (wait_for_inferior): If PRINT_RANDOM_SIGNAL is
2705 defined, call it for signals the debugger doesn't itself use.
2706 The i960 uses this for more detailed fault information.
2708 * remote.c (remote_open): If arg is null, print help rather than
2711 * sparc-xdep.c (register_valid): Avoid declaring size, since
2712 various modules will think of various sizes depending on the
2713 architecture of their tm-file. FIXME, we need protection against
2714 actually entering one of those modules, which would clobber
2715 storage if not for the target architecture compiled into gdb.
2717 * stack.c (up_command, down_command): Always print the frame
2719 (up_silently_command, down_silently_command): New commands
2722 * i960-pinsn.c (reg), i960-tdep.c: Lint.
2724 * i960-tdep.c (i960_frame_chain_valid): Lookup_symbol now takes
2725 more parameters than it used to.
2727 * findvar.c (registers): Increase slop to 256 bytes, which should
2728 protect us against even most RISC machines with large register
2730 (locate_var_value): Move declaration inside related ifdef.
2732 * remote-nindy.c (): Use TIOCSETN rather than TIOCSETP
2733 throughout, to avoid throwing away buffered input from the board.
2734 (nindy_wait): Supply_register takes addr_of_value, not value.
2735 (i960_print_fault): Renamed from i80960_fault.
2736 (nindy_fetch_registers): Avoid have_regs stuff, just get them.
2737 (nindy_store_registers): Avoid regs_changed stuff, just stuff
2739 (nindy_create_inferior): Don't bother to write PC_REGNUM since
2740 we can set the PC in the call to proceed(). Unpush nindy_ops
2741 before pushing it on top, to avoid message to user. Eliminate
2742 commentary from Unix machines that just misleads here.
2743 (reset_command): Fix error message to suggest target command.
2745 Wed Dec 19 11:03:56 1990 John Gilmore (gnu at cygint)
2747 Release 3.92.5 as frozen.
2749 Stabilize the merged release...with help from lint, Saber C,
2752 Everywhere: Add include files needed to declare return types
2753 of functions called.
2755 * gdb.texinfo: Roland Pesch is documenting gdb, glory be!
2757 * breakpoint.h: Add undeclared breakpoint functions, and some
2758 functions for display handling since I couldn't think of a better
2761 * breakpoint.c (insert_breakpoints): Make code for disabling
2762 shared library bkpts more likely to work. It's used when we
2763 rerun a program and stop before the shared library has been
2765 (breakpoint_cond_eval, bpstat_stop_status): Pass arg as int,
2766 cast from pointer, so it squeezes through catch_errors.
2767 (bpstat_stop_status): Fix logic broken some time ago. We now
2768 always create a bpstat if the stop address matches a breakpoint,
2769 even if we don't stop there -- just like the old code used to do
2770 before I got my fingers into it (sigh).
2771 (breakpoint_1): Print "ignore count" after "stop only if"
2772 condition, since that's how it actually works.
2773 (mention): Handle watchpoints as well as breakpoints.
2774 (watch_command): use set_raw_breakpoint and mention to do most
2775 of the work (and initialize all the fields!). Only pass one
2776 arg to parse_c_expression, since that's all it takes.
2778 * command.c (not_just_help_class_command): Rename arg to args
2779 since we ignore "unused argument" warnings on vars named "args".
2780 inflow.c (child_terminal_info): ditto.
2781 infptrace.c (kill_inferior): ditto
2782 main.c (catch_errors, version_info, quit_command, pwd_command,
2783 source_command, dump_me_command, editing_info,
2784 set_history_size_command, set_history, show_history,
2786 stack.c (locals_info): ditto
2787 target.c (target_files_info): ditto
2788 valprint.c (set_input_radix, set_output_radix): ditto
2790 * core.c: Remove old variables for handling core and exec file
2791 sections (data_start, data_end, stack_start, stack_end,
2792 reg_stack_start, reg_stack_end, reg_stack_offset, text_start,
2793 text_end, exec_data_start, exec_data_end, text_offset,
2794 exec_data_offset, data_offset, stack_offset). They're
2795 superseded the more general build_section_table and
2797 (get_exec_file): Mention the `file' command.
2798 (read_memory_check): Rename to memory_error, and only call it
2799 in the case of an actual error.
2800 (read_memory, write_memory): call memory_error.
2801 (core_fetch_registers): Register section name is ".reg".
2803 coredep.c: Remove a bunch of crud now that all this file does
2804 is pull the registers out of a core file.
2805 (fetch_core_registers): Rewrite to actually work, I hope.
2807 dbxread.c: Use a.out.gnu.h, not system a.out, now.
2808 Replace index() with strchr(). Remove all the pre-BFD macro
2809 definitions for accessing the symbol file.
2810 (struct dbx_symfile_info): Encapsulate the information that
2811 dbx_symfile_init needs to pass to dbx_symfile_read in this
2814 (dbx_new_init, dbx_symfile_init, dbx_symfile_read,
2815 dbx_symfile_discard): Rearrange symbol file reading to divide
2816 the format-specific part from the format-independent part,
2817 leaving the format-independent part such as file name expansion
2818 and opening in symtab.c. This replaces
2819 partial_symbol_file_open and partial_symbol_file_read.
2820 Symbol_file_read, add_file, add_file_target_command,
2821 add_file_addr_command move to symtab.c. Pass an explicit
2822 "mainline" flag for when reading the main symbol table, rather
2823 than relying on the offset address to be zero or nonzero.
2825 (dbx_symfile_read): Don't allow void *'s to be printed as
2827 (SWAP_SYMBOL): Use bfd routines to byte-swap the symbols.
2828 (ADD_PSYMBOL_TO_LIST): Make the "function call rather than
2829 macro" debug version really work.
2830 (read_dbx_symtab): Remove unref'd parameter inclink.
2831 Avoid swapping N_SLINE symbols, for speed.
2832 Merge N_TEXT!N_EXT case with the other external symbol
2833 definitions' case. Add comments.
2834 (start_psymtab): Allocate the symfile name in the psymtab on
2835 the psymbol_obstack, rather than using the caller's storage.
2836 (end_psymtab): Only allocate a dependencies list if there are
2838 (psymtab_to_symtab_2): Use BFD when reopening file to read
2839 its symbols for real.
2840 (read_struct_type): Add FIXME comments where it needs work
2842 (read_huge_number): Add FIXME about overflows.
2843 (read_range_type): Add FIXME about comparing a long to 1<<32.
2845 * coffread.c: Minor changes to move things closer to the new
2846 regime with symtab.c and dbxread.c Major work is still needed
2849 * exec.c (exec_file_command): Remove old variables (see core.c
2851 (xfer_memory): If memory transfer is right at the end of a
2852 section, don't lose.
2854 * findvar.c (get_saved_register): If value is in a real
2855 register, LVAL is lval_register, not lval_memory.
2857 frame.h: Declare print_sel_frame and record_selected_frame.
2859 gdb-int.texinfo: New file, for GDB internals documentation.
2860 Very simple, unformatted doc of cleanups is there for now.
2862 gdbcore.h: Remove obsolete variables that described a.out
2863 section addresses and offsets. (See core.c above.)
2864 Declare fetch_core_registers and registers_fetched.
2866 getopt.c: Declare char *alloca(); even on SPARC.
2868 infcmd.c (run_command): Call target_kill rather than
2870 (step_command, next_command, stepi_command, nexti_command):
2871 Declare from_tty parameter even though we don't use it.
2872 (run_stack_dummy): argument BUFFER is a char array, not
2873 a pointer to REGISTER_TYPE.
2874 (finish_command): using_struct_return needed a value *,
2875 not a struct symbol *.
2877 * infptrace.c (child_xfer_memory): To avoid dependency on
2878 where sections are in memory, try PT_WRITE_D and if that fails,
2879 try PT_WRITE_I. Most Unixes don't care which you use.
2881 * infrun.c (step_resume_break_shadow): Change to array to
2882 match other breakpoint shadow storage.
2883 (clear_proceed_status): Pass address of bpstat to
2884 bpstat_clear, not the bpstat itself.
2885 (child_create_inferior): FIXME comment about if the child
2887 (start_inferior): Remove old function.
2888 (child_open): Use target_kill rather than kill_inferior.
2889 (wait_for_inferior): Ditto.
2890 (insert_step_breakpoint, remote_step_breakpoint): Use
2891 new step_resume_break_shadow.
2893 * inftarg.c (child_wait): If all child processes die,
2894 pretend that the one being waited for exited with signal 42.
2896 * main.c (command_line_input): When scanning for comments,
2897 don't coredump on unclosed quotes.
2898 (quit_command): Use target_kill rther than kill_inferior.
2899 (_initialize_main): Rename class_user from "user" to
2902 * printcmd.c (print_command_1): Initialize "fmt" if no format
2903 is specified by the user.
2904 (print_frame_args): Only add to args_printed if we are
2905 actually fetching args from the stack (avoiding undefined
2907 (_initialize_printcmd): Remove bogus \{ from string.
2909 * remote-eb.c (eb_open): Avoid coredump on no argument.
2911 * remote-nindy.c: Bring out of Intel environment into new
2912 target environment. Remove all conditional compilation on
2913 I80960. Massive hacking throughout.
2914 (nindy_xfer_inferior_memory): New routine stolen from
2916 (nindy_create_inferior): New routine pieced together, probably
2917 not quite working yet.
2918 (nindy_ops): New target_ops struct for nindy.
2920 * remote-vx.c: Use write_memory rather than target_write_memory
2921 to get error checking.
2922 (vx_add_file_command, vx_open): Use symbol_file_add rather than
2924 (vx_create_inferior): Use target_terminal_ours...
2926 * signame.c (_initialize_signame): Always initialize, since
2927 we need the table for things other than psignal.
2929 * solib.c (solib_add): Use symbol_file_add, not add_file.
2930 (solib_address): Return boolean result rather than struct
2931 pointer which nobody else knows the type of.
2933 * sparc-tdep.c, valops.c: Use write_memory rather than
2934 target_write_memory, to get error checking.
2936 * stack.c (locals_info, catch_info, args_info,
2937 get_selected_block, frame_command, up_command): Use
2938 target_has_stack, rather than have_inferior_p or
2941 * sun3-xdep.c (fetch_core_registers): Rewrite for new BFD regime.
2943 * symfile.h: New file, defining the interface between the
2944 generic and object-file-specific symbol reading code.
2946 * symtab.c: Move generic symbol-reading interface to symtab.c,
2947 from dbxread.c, coffread.c, mipsread.c, etc. Add symtab_fns
2948 table to map BFD targets to symbol-reading modules in GDB.
2949 Change index to strchr.
2950 (lookup_struct_elt_type): Use error() rather than hand-made
2951 simulations thereof.
2952 (lookup_partial_symbol): Speedup slightly when length == 0.
2953 (symbol_file_add): New function.
2954 (symbol_file_command): Call it.
2955 (symfile_open, symfile_init): New function.
2956 (add_file_target_command, add_file_addr_command): moved from
2959 * target.c (target_command): use target_kill.
2961 * target.h (target_files_info): Don't declare, never called
2964 * tm-sun2.h, tm-sun3.h (STACK_END_ADDR): Use system include
2965 files to determine stack end address.
2967 * valarith.c (value_x_binop, value_x_unop): Change error message
2968 to be more useful. Pass proper argument to value_struct_elt.
2970 * valops.c (value_assign): FIXME comment that long long
2971 bitfields will break here.
2973 * Makefile.dist: Add symfile.h, remote-nindy.c, remote-eb.c.
2974 Update `make saber_gdb' to work better.
2976 * TODO: A woman's work is never done.
2978 * cplus-dem.c, environ.c, inferior.h, infrun.c, inftarg.c,
2979 main.c, obstack.c, printcmd.c, remote-eb.c, remote-nindy.c,
2980 remote-vx.c, remote.c, solib.c, source.c, sparc-pinsn.c,
2981 sparc-tdep.c, sparc-xdep.c, symmisc.c, symtab.c, symtab.h
2982 target.c, terminal.h, tm-sparc.h, tm-sunos.h, utils.c,
2983 valops.c, valprint.c, exec.c: Lint.
2986 Wed Dec 12 23:44:15 1990 John Gilmore (gnu at cygnus.com)
2988 Continuing Intel 960 port merge of GDB.
2990 * Makefile.dist: Merge i960 "nindy-share" files. Rename
2991 malloc.h to gmalloc.h to avoid name conflicts in /usr/include.
2992 Don't ship gdb.dvi in tar file. Link gdb with init.o, not init.c.
2993 Wack over "make depend" so it handles files in subdirectories
2994 vx-share, nindy-share, bfd, and in the current directory.
2996 * blockframe.c (get_prev_frame_info): Remove fatal error
2997 if stack not defined.
2999 * core.c (core_open, core_detach): New functions that handle
3000 the old "core-file" command as "target core" and "detach" instead.
3001 (core_file_command): Call them.
3002 (core_xfer_memory): Use common routine xfer_memory.
3004 * dbxread.c: Include a.out.gnu.h, not system a.out.h.
3005 dbxread now uses bfd for everything but symbol reading itself.
3006 BFD internals are used to drag out the relevant file offsets.
3007 (partial_symbol_file_open): Change args all around for BFD.
3009 * symtab.c: Rename "value" to "val" everywhere, so we can
3011 (symbol_file_command): New command, moved from dbxread.c
3012 and coffread.c. It uses BFD to read the file, then vectors
3013 based on its type, to dbx or coff symbol readers.
3014 * symtab.h: Extern a few vars for symbol_file_command.
3016 * target.h: Breakpoint takes a char * save area, not a char **.
3018 * valprint.c (val_print): When unpacking bitfields, offset
3019 the address in gdb of the value, if it is declared with a shorter
3020 type. Remove the last "runtime kludge test" of host byte order.
3022 * utils.c: Remove old my_bfd_read routine.
3024 * stack.c (frame_info): Use target_has_stack. Print program counter
3025 register's actual name rather than "pc", since it's called the
3026 "ip" (instruction pointer) on the i960 (sigh).
3028 * target.c (target_command): Add command for selecting a target
3029 type and calling its open routine. This is used for initiating
3030 communication with a particular target, in a generic way.
3032 * tm-i960.h: Update for modern gdb. Remove semicolons from
3033 various macros. Handle reading struct return convention, and
3034 error-out attempts to return structs with the "return" command.
3035 Be sure gdb doesn't think we know how to call functions in the
3038 * i960-tdep.c: Rename FRAME_CHAIN_VALID and FRAME_FIND_SAVED_REGS
3039 to i960_xxx in lower case.
3040 (arg_address): Circumvent errors due to LOC_ARG_BLOCK
3041 not being defined yet.
3043 * remote.c (remote_open): Call start_remote to initialize
3044 wait_for_inferior during open.
3045 (remote_xfer_inferior_memory): Return length written rather
3048 * remote-vx.c (target_command -> vx_open): Use new generic
3050 * remote-eb.c, inftarg.c, exec.c: ditto.
3052 * infrun.c: Fix comments.
3053 (attach_program -> child_open): Use new generic target command.
3054 (wait_for_inferior): Clear saved register values before target_wait,
3055 so target_wait can set some of them if convenient.
3057 * infptrace.c (fetch_inferior_registers, store_inferior_registers):
3058 Return success indicator, not void.
3059 (child_xfer_memory): Avoid fetching initial word if we'll
3060 overwrite it anyway.
3062 * infcmd.c (attach_command): Use new generic target open routine.
3063 (_initialize_infcmd): Update doc on attach and detach commands.
3064 (do_registers_info): Merge in a byte-order problem as a FIXME
3067 * findvar.c (find_saved_register): Avoid problem in current frame.
3068 (read_relative_register): Ditto.
3069 (write_register): Convert byte order on the way out.
3071 * exec.c (file_command): Add.
3072 (add_to_section_table, exec_command): Use new bfd_map_over_sections.
3073 (xfer_memory): Common function between core_xfer_memory and
3075 (exec_xfer_memory): Use it.
3077 * pn-opcode.h: Document that a "PN" is a Gould PowerNode.
3079 * breakpoint.c, breakpoint.h, symtab.h, value.h, frame.h, utils.c,
3080 valops.c, stack.c, target.c, sparc-xdep.c, source.c, printcmd.c,
3081 infcmd.c, i960-pinsn.c, eval.c, defs.h: lint and gcc -Wall.
3083 Sun Dec 2 16:45:06 1990 John Gilmore (gnu at cygnus.com)
3085 Merge Intel 960 port of gdb, continuing...
3087 * dbxread.c (partial_symbol_file_open, partial_symbol_file_read,
3088 symbol_file_command): Pass from_tty arg to hush 'em up.
3090 * coffread.c (symbol_file_command): Avoid output if from_tty != 1.
3091 Add magic numbers for 960 COFF format.
3093 Fri Nov 30 09:18:20 1990 John Gilmore (gnu at cygnus.com)
3095 Merge Intel 960 port of gdb, from Intel "1.2" release.
3097 CHANGE_LOG entries from their port, which was based on
3100 Thu Sep 6 11:02:22 PDT 1990
3101 Remove temp file if download is interrupted.
3103 Wed Aug 1 09:08:33 PDT 1990
3104 Now uses binary protocol to talk to NINDY.
3105 Old hex protocol (NINDY 2.13 and older) supported with -O switch.
3106 Times out after 5 seconds when trying to talk to NINDY.
3108 Tue May 29 12:54:49 PDT 1990
3109 Added variable baud rate (-b switch).
3110 Source code reorganization.
3112 Thu Apr 26 11:09:55 PDT 1990
3113 More cleanup of batch mode; specifically, execute "-s", "-e", and
3114 "-se" switches as soon as they are encountered on the invocation line.
3116 Fri Apr 20 13:47:15 PDT 1990
3119 Thu Apr 19 09:54:28 PDT 1990
3120 Add 'reset' command.
3122 Wed Apr 18 09:48:07 PDT 1990
3123 After opening remote tty, wait for 1 second to go by without input
3124 from it before trying to talk to NINDY (fixes problems with the
3125 Heurikon HK80/V960E).
3127 Mon Apr 4 16:33:05 PDT 1990
3128 Some output was not being suppressed in 'batch' mode.
3130 Thu Mar 22 15:31:11 PST 1990
3131 Ask user if old symbol table should be deleted when new file is
3134 Allow user to run a program downloaded before gdb960 was brought up.
3136 Correct "exec-file" help message for i80960 context.
3138 Correct bug in calculating user space address: could occasionally
3139 corrupt user program.
3141 Make sure to zero low-order bits in rip's because of bug in 960CA
3142 A-step part: could cause operation faults when "next"ing across
3145 Correct bug that made it impossible to get source line numbers for
3146 code loaded at addresses higher than 0x7fffffff.
3148 Wed Jan 10 12:43:22 PST 1990
3149 Open remote tty for exclusive use.
3151 Fri Jan 5 12:14:42 PST 1990
3152 Correct disassembly (CA manual was right after all):
3153 opcode for sysctl is 0x659
3155 Mon Oct 23 12:03:04 PDT 1989
3156 Use G960BASE and G960BIN environment variables to find 'sx' utility.
3158 Mon Oct 16 14:15:09 PDT 1989
3159 "sfr0"-"sfr31" should have been named "sf0"-"sf31"
3161 Mon Oct 2 15:56:31 PDT 1989
3163 Added 960CA disassembly support.
3165 To simplify maintenance:
3166 - eliminated use of symblic links on pinsn.c: use i960-pinsn.c
3168 - eliminated opcode.h: incorporates tables into i960-pinsn.c
3169 - moved 960-specific routines from i960-pinsn.c to i960-md.c
3170 - made disassembly interface identical to that in gdmp960.
3174 Wed Nov 28 21:32:48 1990 John Gilmore (gnu at cygint)
3176 * target.h: Allow targets to stack. Add target_has_memory,
3177 _registers, etc. Restructure memory access and "info files"
3178 to walk the target stack.
3179 * exec.c, core.c, inftarg.c, remote.c, remote-vx.c, remote-eb.c,
3180 target.c: Change tables to match target.h.
3181 * inflow.c (child_mourn_inferior): pop child_ops.
3182 (generic_mourn_inferior): Use new has_stack flag.
3183 * infptrace.c (child_xfer_memory): New memory regime.
3184 * inftarg.c (child_files_info): New "info files" regime.
3185 * remote-eb.c: New memory regime, new info files.
3186 * remote-vx.c: New memory regime, new info files. Now use
3187 separate targets for VxWorks attachment to machine, and
3188 actually running a process under VxWorks, since one has
3189 stack & execution & regs and the other doesn't.
3190 * remote.c: New memory regime, new info files.
3191 * sparc-xdep.c (fetch_core-registers): New memory regime.
3192 * target.c: New routines and support for stacked targets,
3193 new memory regime, new info files regime.
3196 Generalize section handling for an arbitrary number of sections,
3197 including use of the new BFD (binary file) library.
3198 * gdbcore.h: Add struct section_table.
3199 * exec.c (build_section_table): Iterate all sections and
3200 record what gdb needs to know about them.
3201 (exec_command): Use it.
3202 (exec_xfer_memory): Use the table.
3203 (exec_files_info): Print the table.
3204 * core.c (core_file_command, core_xfer_memory, core_files_info):
3206 * source.c (find_source_lines): Use bfd_get_mtime.
3207 * dbxread.c: Quick changes to make it compile with new BFD.
3208 * utils.c (error): Avoid using bfd_error in generic routines.
3210 * core.c (core_fetch_registers): Get from the ".regs" section of
3212 * sparc-xdep.c (fetch_core_registers): Use the .regs info.
3214 * inferior.h (attach_flag): Export.
3215 * infcmd.c (run_command): use new target_create_inferior.
3216 * infrun.c (child_create_inferior): Don't return result.
3217 * Makefile.dist (VERSION): 3.91.4.
3219 Fri Nov 23 28:15:38 1990 John Gilmore (gnu at cygint)
3221 * breakpoint.c (bpstat_num): Handle breakpoints which have
3222 since been deleted, such as temporary breakpoints.
3223 infcmd.c (program_info): ditto.
3225 * core.c (core_file_command): Display the frame where the core
3230 * remote-vx.c (target_command): Merge in target command from
3231 targ-vx.c. A few other cleanups.
3233 * TODO, Projects: Lots more stuff to do...
3235 Fri Nov 23 18:15:38 1990 John Gilmore (gnu at cygint)
3237 Massive changes to wall off the remote-debugging interface
3238 behind a function vector. The port to handle VxWorks targets
3239 is also part of this.
3241 All files: Replace references to renamed functions,
3242 remove references to remote_debugging, remove references to
3243 have_include_file, have_core_file in favor of target_has_stack,
3244 target_has_memory, etc.
3246 * Modularize the breakpoint interface.
3247 breakpoint.h (BREAKPOINT_MAX): New define sets max length of
3248 a breakpoint instruction.
3249 breakpoint.c: struct breakpoint's shadow_contents now sized as
3251 (insert_breakpoints): Vector to target to install breakpoints.
3252 (remove_breakpoints): Vector to target here too.
3253 Remove REMOTE_SA_SPARC kludges and other remote_debugging.
3254 sparc-tdep.c (single_step): Use new breakpoint interface for
3255 the single-step breakpoints.
3256 mem-break.c (memory_insert_breakpoint, memory_remove_breakpoint):
3257 New file, contains routines to insert and remove breakpoints by
3258 reading out the old contents and later replacing them. This is
3259 how ptrace breakpoints work, and many remote systems as well.
3261 * tm-vxworks68.h: New config file, overrides a few things for
3262 Wind River's preferences.
3264 * target.h: New file, for transfer vector used to talk to the
3265 inferior (child, attached, core, exec, remote, etc). All accesses
3266 to the thing being debugged should come through these vectors.
3267 target.c: New file, routines to handle transfer vector.
3268 (various files): Add transfer vectors XXX_ops for the various
3269 targets and pseudo-targets (core files, etc) we support.
3271 * breakpoint.c (bpstat_stop_status): Further explorations of
3272 watchpoints and why things don't work all the time.
3273 (bpstat_alloc): New fn to allocate a bpstat and chain it.
3275 * config.gdb: Only add "source ${srcdir}/.gdbinit" to
3276 the local gdbinit if it doesn't already have it.
3278 * core.c (core_ops): add and install.
3279 Allow core debugging without exec file.
3281 * dbxread.c (free_and_init_header_files): Merge two fns.
3282 (end_symtab): Free named symbol table when a new version comes in.
3283 (read_dbx_symtab): Relocate all kinds of symbols with base
3284 address. First step toward handling different text, data, bss
3286 (add_file_addr_command): Renamed add_file_command.
3287 (add_file_command): Vector to remote handler.
3288 Add "load" as an alias for "add-file" command.
3290 * defs.h: Allow "volatile" to be used in non-ANSI; use it for
3291 non-returning functions.
3293 * exec.c: Add exec_ops, and push it as a target when an exec
3296 * infcmd.c (run_command): Pass executable file name and arg list
3297 separately when starting an inferior. Permit "run" when no exec
3298 file is specified, for VxWorks.
3299 (detach_command): Move to child_detach in inftarg.c.
3301 * inftarg.c: New file. Unix-child-specific routines, and the
3302 child_ops structure.
3304 * inferior.h (registers): Export "registers" as the way for
3305 target dependent register handlers to find gdb's local copy of
3306 the registers. Rename "stop_after_attach" to "stop_soon_quietly"
3307 since it is now used by places that want wait_for_inferior to
3308 handle the grunge but want to see every trap from the inferior.
3310 * inflow.c (create_inferior): Pull out, and merge into infrun.c.
3311 Eliminate remote_debugging hooks in terminal handling.
3313 * infrun.c: Replace start_inferior with child_create_inferior.
3314 Move all the hair of Unix shells and ptrace idiosyncracies into
3315 child_create_inferior, so remote handlers don't have to deal.
3316 Remove running_in_shell. Rename stop_after_attach to
3317 stop_soon_quietly, and use it in a few other places where we want
3318 to just call wait_for_inferior and get control back on the first
3319 trap. trap_expected now never takes a value > 1.
3320 (init_wait_for_inferior): Initialize static vars when a new
3323 main.c (gdbinit): Add new hook for .gdbinit file name, let
3324 it be overridden by config files as GDBINIT_FILENAME.
3325 (DEFAULT_PROMPT): Add new hook for overriding (gdb) prompt.
3326 Both of these are used for VxWorks gdb.
3328 mcheck.c: rename include file "gmalloc.c" to avoid problems
3329 with system include file "malloc.c".
3331 param-no-tm.h: New include file, same as param.h but does not
3332 include the default "tm.h" file. This is used in files where
3333 the target is known, e.g. remote-eb.c or sparc-xdep.c.
3335 param.h: Now just a shell that includes tm.h and param-no-tm.h.
3337 remote-vx.c: New file, VxWorks remote debugging support. Uses
3338 RPC routines that are shared with the target system, in directory
3341 remote.c: Vectorize remote interface.
3343 source.c: Globalize source_path, and make an alias "l" for "list"
3344 since we now have the "load" command.
3346 sparc-xdep.c: Use new param-no-tm.h.
3348 symmisc.c (free_named_symtab): Add new function from Wind River.
3349 However, ifdef it out for now while we think about what it should
3352 tm-sun3.h, xm-sparc.h, xm-sun3.h, xm-symmetry.h: Move
3354 the xm- file, and change its name to CHILD_PREPARE_TO_STORE, since
3355 non-Unix-children handle this with their own code in the target
3358 Makefile.dist: Roll version to 3.92.3. Add vx-share stuff to
3359 source and target lists. Add vx-share to default list of include
3360 directories. Add new files to src and target lists: mem-break,
3361 target, inftarg, remote-eb, remote-vx, targ-vx. Be sure the
3362 ${srcdir} versions of munch and createtags are used.
3364 * valops.c (find_function_addr): Split out of call_function.
3365 (call_function_by_hand): Rename call_function; this function
3366 calls functions in the target by laboriously patching the target
3367 word-by-word with the right stack, args, regs, etc.
3370 Mon Nov 5 17:29:10 1990 John Gilmore (gnu at cygint)
3372 Handle AMD 29000 a bit better.
3374 * remote-eb.c (readchar): Mask received char log to make it readable.
3375 (remote_start): Pass arguments down to executing program.
3376 Make startaddr unsigned.
3377 infrun.c (start_inferior): Accept args, pass them to
3379 infcmd.c (run_command): Pass args down to start_inferior.
3381 * tconfig/am29k-aout, tconfig/am29k-coff: New files specifying
3382 the target object file format.
3383 tm-29k.h: Pay heed to COFF_ENCAPSULATE.
3385 * am29k-pinsn.c (print_insn): Print 0x on hex numbers in disassembly.
3386 am29k-tdep.c (examine_prologue): Better checking of function prefixes.
3388 Sun Oct 7 18:20:45 1990 John Gilmore (gnu at cygint)
3390 * Makefile.dist (VERSION): Roll version to 3.91.9 and freeze.
3391 * TODO: We did a few things, we have more to do though.
3393 * xm-sparc.h (CLEAR_DEFERRED_STORES): Define.
3394 * inflow.c (inferior_died): Clear deferred stores.
3396 * Debug problems with dummy frames and calls to the inferior.
3397 * tm-sparc.h (PUSH_DUMMY_FRAME, POP_FRAME): Move to sparc-tdep.c.
3398 * sparc-tdep.c (do_restore_insn): Simplify.
3399 (sparc_frame_find_saved_regs): Simplify and fix what we find.
3400 (sparc_push_dummy_frame): Simplify and fix what we push.
3401 (sparc_pop_frame): Slightly more hair here, deciding whether
3402 we are restoring a saved PC or returning to a return address in %i7.
3403 * sparc-xdep.c (read_inferior_registers): Debug if valid reg is read.
3405 * utils.c (xmalloc, xrealloc): Return type depends on __STDC__.
3406 * symtab.h (xmalloc): ditto, for obstack_chunk_alloc.
3407 * obstack.h (chunkfun): ditto.
3408 * defs.h (xmalloc, xrealloc): ditto
3410 * utils.c (quit): Grab the terminal from the child if necessary.
3412 * inflow.c (term_status_command): Rename to term_info, change
3415 * sparc-pinsn.c (print_insn): Disassembly prefers real instructions.
3416 (is_delayed_branch): Speed up.
3417 * sparc-opcode.h: Add ALIAS bit to aliases. Fix up opcode tables.
3418 Still missing some float ops, and needs testing.
3420 * Support for input and output radixes other than base 10
3421 * defs.h (input_radix, output_radix): Declare.
3422 * expread.y (yyparse, parse_number): Handle changes of input
3423 radix, and ambiguous names-or-numbers in radixes >10.
3424 * printcmd.c (print_scalar_formatted): Print formatted hex
3425 numbers in varying column widths.
3426 * valprint.c (val_print): Use output_format to print scalar ints.
3427 (set_input_radix, set_output_radix, set_radix): Create.
3428 (set_output_radix): Set output_format from output_radix.
3429 (_initialize_valprint): add `set radix' but leave the others off.
3431 * main.c (execute_command): Let stupid questions be turned off.
3432 (_initialize_main): Handle "set stupidity", etc.
3434 * main.c, inflow.c, inferior.h, frame.h, command.c, defs.h,
3435 sparc-pinsn.c, sparc-xdep.c, value.h, valops.c, values.c: Lint.
3437 Tue Oct 2 11:20:02 1990 John Gilmore (gnu at cygint)
3439 * TODO, Makefile.dist, ChangeLog: Freeze for 3.91.8 release.
3440 bfd stuff is still screwed up, but with some manual work, it
3443 * breakpoint.c (bpstat_do_actions): Start over if a command
3444 proceeds the inferior, since the inferior will have stopped and
3445 will need to have its new stop-actions taken care of.
3447 * dbxread.c (read_struct_type): Expression gives Sun3 4.0.3
3448 compiler fits, simplify it.
3450 * gdb.texinfo (directory command): Doc new dir command.
3451 source.c (directory_command): "dir" now puts things on the front
3452 of the path, moves dups up front, and handles multiple names
3453 on the command line, inserting each one in order. It also
3454 blows away cached line and full_filename info.
3456 * stack.c (backtrace_command): Skip "more stack frames follow"
3459 * Change #ifndef HAVE_VPRINTF to #define MISSING_VPRINTF in
3460 xm-convex.h, xm-hp300bsd.h, xm-isi.h, xm-merlin.h, xm-news.h,
3461 xm-np1.h, xm-pn.h, xm-pyr.h, xm-symmetry.h, xm-umax.h, xm-vax.h.
3462 The only odd one was Gould NP1, which had defined vprintf to
3465 * Merge Ted Goldstein <tedg@Eng.sun.com>'s changes for epoch.
3466 printcmd.c (print_command_1): Pass 'inspect' flag down as a global
3467 variable, inspect_it.
3468 valprint.c (print_string, val_print): Use the global inspect_it
3469 to indicate whether to print in Epoch style or normal style.
3471 Mon Oct 1 23:55:26 1990 John Gilmore (gnu at cygint)
3473 * printcmd.c (call_command): add an alias for the "print" command
3474 which runs expressions and doesn't print the result if void.
3475 (print_command_1): implement it.
3477 * command.c: Remove #if 0'd code. Initialize all the fields
3478 in add_cmd (). Rename do_nothing_command to
3479 not_just_help_class_command, and make it externally visible.
3480 command.h: add user_commands to struct.
3481 * main.c (define_command): Don't overload c->function with a char
3482 string as well as a function pointer.
3484 * eval.c (evaluate_subexp): Reinstall tiemann changes to
3485 calling convention of value_struct_elt () that got dropped in
3488 * tm-sparc.h (FRAME_FIND_SAVED_REGS): move to sparc-xdep.c.
3489 sparc-tdep.c (sparc_frame_find_saved_regs): ditto.
3491 * tm-sparc.h (POP_FRAME): replace some constants with defines.
3493 * sparc-xdep.c (store_inferior_registers): defer stores to regs
3494 until a good time (e.g. when we are about to run the child),
3495 saving ptrace calls.
3496 * infrun.c (proceed): handle DO_DEFERRED_STORES.
3497 * tm-sparc.h: define DO_DEFERRED_STORES.
3499 * sparc-xdep.c (store_inferior_registers): when storing float
3500 registers, don't store stack regs too. When storing the SP,
3501 however, DO store the stack regs too. This fixes a bug in which
3502 the dummy frame is not recognized when a call_function finishes,
3503 because its frame pointer (in the stack regs) was never
3505 (read_inferior_registers): Mark WIM and TBR and FPS and CPS valid
3506 even though we don't know how to read them from an inferior.
3507 valops.c (call_function): Comment about storing SP.
3509 * infrun.c (save_inferior_status): Save away the original bpstat
3510 chain so it can be restored later. Install the copied version for
3511 use by whoever saved the status. It will be blow away by
3512 restore_inferior_status, and the original chain restored. This is
3513 important for people who have pointers into the original.
3515 * breakpoint.c, command.h, copying.awk, dbxread.c, defs.h,
3516 findvar.c, frame.h, obstack.h, obstack.c, inflow.c, value.h,
3517 main.c, printcmd.c, sparc-tdep.c, symtab.c, valprint.c: lint
3520 Fri Sep 28 20:32:46 1990 John Gilmore (gnu at cygnus.com)
3522 * Makefile.dist: Roll version to 3.91.8. Add bfd.h and bfdconfig.h
3523 temporarily to the makefile. Add am29k-opcode.h and WHATS.NEW.
3524 Add stuff.c and kdb-start.c to the OTHERS list for tar files.
3526 Fri Sep 28 19:12:12 1990 John Gilmore (gnu at cygint)
3528 * Merge Mike Tiemann's multiple inheritance changes from Sun.
3529 Store the baseclasses in a type struct starting from array element
3530 0 rather than from the unusual array element 1.
3532 dbxread.c: the above.
3533 (virtual_context): Add
3534 Read new debug information about which virtual function table
3535 a virtual function is from, and store it in fn_field.fcontext.
3537 symtab.h: Add fcontextt. Fix baseclass indices. Typo in
3538 TYPE_FN_FIELD_STATIC_P.
3540 symtab.c: the above.
3541 valops.c: the above. Handle pointer casts of object *'s.
3542 (search_struct_method): Add.
3543 (value_struct_elt): First arg is now a pointer to a value, and is
3546 valprint.c: the above.
3547 values.c (value_virtual_fn_field): Add type arg. Handle
3548 offsetting to the proper object when calling virtual fns.
3550 (baseclass_addr): Add valuep arg.
3552 * README: Document the current state of BFD config (missing).
3553 * TODO, ChangeLog, Makefile.dist: Roll version.
3554 * WHATS.NEW: Add summary of changes since 3.5.
3556 Thu Sep 27 16:23:12 1990 John Gilmore (gnu at cygint)
3558 * dbxread.c (read_struct_type): Clear bit vectors whenever
3560 symtab.c (B_CLRALL): define.
3562 * tm-sparc.h (STORE_RETURN_VALUE): Avoid clobbering types by
3563 using == rather than =. Huh... This fixes the dreaded problem
3564 wherein builtin_type_int becomes TYPE_CODE_FLT.
3566 * core.c (info_files): Show the inferior pid.
3568 * config.gdb: Avoid putting "dir" command into .gdbinit. GDB
3569 already knows how to look in the source directory.
3571 * Remove psymtab hair from many places. Remove duplicated code
3572 for searching symbol tables. Hide psymtabs from most places.
3573 Make it fast to get from a psymtab to its symtab.
3575 blockframe.c (blockvector_for_pc): Remove psymtab hair.
3576 coffread.c (psymtab_to_symtab): Rename to psymtab_to_symtab2.
3577 mipsread.c (psymtab_to_symtab): Rename to psymtab_to_symtab2.
3578 dbxread.c: export psymtab_to_symtab, make it work if called N times.
3579 (psymtab_to_symtab): Rename to psymtab_to_symtab2. Initialize
3580 new symtab completely. New psymtabs get symtab pointer
3581 initialized to zero. Remove MI warning printf.
3582 symtab.h: Comments. Add psymtab to symtab pointer.
3583 (PSYMTAB_TO_SYMTAB): New macro.
3584 symtab.c: use PSYMTAB_TO_SYMTAB. Add psymtab_to_symtab and export it.
3585 source.c: use PSYMTAB_TO_SYMTAB. Remove symtab version and
3587 stack.c (backtrace_command): Avoid pre-pass to read symbols, if
3589 (print_frame_info): Avoid special-casing symbols that have not yet
3592 * source.c (open_source_file): Quick path if we have already
3593 located the source file by its full name.
3595 * symtab.c (lookup_symbol): Use find_pc_symtab rather than
3596 find_pc_psymtab. When a name is found in the misc function
3597 vector, search the symbol table for its mangled name, not the
3598 name that the user typed.
3600 * bfd.h: Fix missing comment terminators, make #endifs match.
3602 * valarith.c (value_less): Handle unsigned int comparisons.
3603 Add FIXME about pointer compares, which assume host and target
3604 pointers are the same.
3606 * command.c (do_nothing_command): lint
3607 dbxread.c: lint. Remove sort_syms. Document C++ visibility info,
3608 fix comments on debug symbol format for visibility. Actually set
3609 visibility of symbols.
3610 main.c (echo_command): lint; use <readline/history.h>.
3611 tm-sparc.h (FRAME_FIND_SAVED_REGS): lint
3612 obstack.h (_obstack_blank): Rearrange pointer math to avoid
3613 pointing past end of allocated memory; saber complains.
3614 obstack.h: Declare the external functions that we use.
3615 valarith.h: use <string.h>
3616 solib.c (solib_add): lint.
3618 Fri Sep 21 17:05:19 1990 John Gilmore (gnu at cygint)
3620 * main.c (initialize_main): Default info_verbose to off, now that
3621 symbol reading is fast.
3622 (quit_command): Avoid clobbering exec_bfd while quitting.
3624 * Initial BFD (binary file diddling library) merger:
3625 coffread.c: Change AOUTHDR to struct exe_hdr.
3627 core.c: initialize initialized data at compile time.
3628 (core_file_command): Move from coredep.c, convert to bfd.
3629 (xfer_core_file): Convert to bfd.
3630 exec.c (exec_file_command): use bfd routines.
3632 mips-tdep.c: Remove exec_file_command and friends.
3635 * coredep.c: (fetch_core_registers) Convert core_file_command to
3636 fetch_core_registers.
3637 mips-xdep.c, sparc-xdep.c, sun3-xdep.c: ditto.
3639 * utils.c: (error): Bogus crap, FIXME, to print bfd errors.
3640 (my_bfd_read): More bogosity, which I don't think we call.
3641 (program_name): Remove this atrocity asap!
3643 Wed Sep 19 13:36:41 1990 John Gilmore (gnu at cygint)
3646 values.c: allocate_repeat_value was not clearing the
3647 optimized_out field.
3648 (value_static_field): minor stylistic fix (wrong macro was used).
3649 valops.c (value_struct_elt_for_address): didn't work for C++
3652 * signame.c (_initialize_signame): Initialize signal names once.
3654 * breakpoint.h, command.c, copying.awk, defs.h, environ.c,
3655 exec.c, frame.h, infcmd.c, inferior.h, main.c, munch, sun3-xdep.c,
3656 symtab.h, tm-29k.h, valprint.c, value.h, values.c: Lint.
3658 * remote-eb.c: Support user-settable baud rates on the serial port.
3660 * tm-sun3.h (PREPARE_TO_STORE): fix typo.
3662 Fri Sep 14 13:28:29 1990 John Gilmore (gnu at cygint)
3664 * tconfig/sun3os4: Remove warning about native assembler,
3665 since it also occurs in the xconfig file.
3667 * findvar.c (registers): Allocate some slop after `registers'
3668 to prevent stray accesses from trashing the next variable.
3670 * tm-68k.h (REGISTER_BYTES): Allocate the right number of bytes
3671 on the sun-3, by changing the #ifdef from `sun3' (which is not
3672 defined by cc) to `sun'. Symptom was trashed builtin_type_XXX
3673 vars, which happened to follow `registers' in the executable.
3675 * readline/history.c (history_search): Heed gcc-2's advice
3676 and parenthesize && inside ||).
3678 * am29k-opcode.h, am29k-pinsn.c, am29k-tdep.c, remote-eb.c,
3679 tm-29k.c: Insert FSF copyright headers.
3681 * remote-eb.c: Better comments.
3683 * Makefile.dist: Update to 3.91.6.
3684 * TODO: note PREPARE_TO_STORE problem.
3686 Thu Sep 13 09:52:33 1990 Jim Kingdon (kingdon at cygint)
3688 * stack.c (frame_info): Only use FRAME_FIND_SAVED_REGS if defined.
3690 * remote.c: Wrap the whole file in #if !defined (SPECIAL_REMOTE).
3692 * infrun.c (wait_for_inferior, at end): Don't set up
3693 prev_* if the inferior no longer exists.
3695 * inferior.h (CALL_DUMMY_LOCATION): New macro, to replace
3696 CANNOT_EXECUTE_STACK.
3697 valops.c (call_function): Use it.
3699 * tm-convex.h: Add CALL_DUMMY_LENGTH for use by PC_IN_CALL_DUMMY.
3701 * inferior.h (PC_IN_CALL_DUMMY): New macro.
3702 infrun.c (wait_for_inferior, 2 places): Use it.
3704 * values.c (value_being_returned): Only use
3705 EXTRACT_STRUCT_VALUE_ADDRESS if defined.
3707 * Move PREPARE_TO_STORE from xm-sun3.h to tm-sun3.h to do the
3708 right thing for remote-eb.c.
3710 * sun3-xdep.c: Remove extraneous call to remote_store_registers.
3711 * sun386-xdep.c, hp300hpux-xdep.c, sparc-xdep.c: Ditto.
3713 * blockframe.c: Put get_frame_saved_regs inside #if !defined
3714 (FRAME_FIND_SAVED_REGS).
3716 * findvar.c ({fetch,store}_registers): Check for
3717 REMOTE_{FETCH_STORE}_REGISTER macro.
3719 * findvar.c (get_saved_register): Add argument lval and
3720 change meaning of argument addr.
3721 findvar.c: Change calls to get_saved_register to reflect
3722 new calling convention.
3723 valops.c (value_assign): Use get_saved_register instead of
3724 find_saved_register.
3726 Sun Sep 2 12:40:20 1990 Jim Kingdon (kingdon at cygint.cygnus.com)
3728 * coffread.c (read_one_sym): Make temp_aux an AUXENT, not
3729 an (uninitialized) pointer to one. Use "&" when passing it
3732 Fri Aug 31 22:57:54 1990 Jim Kingdon (kingdon at cygint.cygnus.com)
3734 * coffread.c (getfilename): Use DGUX x_offset and x_name if
3737 * coffread.c (symbol_file_command): Put semicolon after
3739 Put safe_to_init_tdesc_context in #if defined (TDESC).
3740 Put #ifdef TDESCs in 1st column for non-ANSI cpp's.
3741 coffread.c: #include <sys/stat.h>.
3742 (read_coff_symtab): Typo: in_source_files -> in_source_file.
3743 Add missing ')' in check for "lc%" and friends. Remove
3745 Declare read_one_sym() at top of file.
3746 (read_file_hdr): Put in extra #ifdefs so MC68MAGIC and
3747 MC68WRMAGIC can have the same value without causing a duplicate
3750 Thu Sep 13 15:55:36 1990 John Gilmore (gnu at cygint)
3752 * Allow a Makefile to be built without building the
3753 tm and xm file links that screw up builds in subdirectories.
3754 This is done with `config.gdb none', then you can do things
3755 like `make gdb.tar.Z'.
3756 * tconfig/none: Config file for no target system
3757 * xconfig/none: Config file for no host system
3758 * config.gdb: If no TM or XM files are called out by the
3759 host or target file, don't make links for them.
3761 * cplus-dem.c: Add documentation.
3763 * dbxread.c (read_ofile_symtab): Turn a fatal error into a
3764 simple error, so the user's gdb doesn't crash due to some object
3765 file problem (e.g. somebody is rebuilding the file out from under
3768 * printcmd.c (print_address_symbolic): demangle the symbol.
3770 * Makefile.dist (OTHERS): Remove tdesc-lib because it has
3771 Motorola copyrights in it. Make "make gdb.tar.Z" work.
3772 (alldeps.mak): sort and uniq all results from this; duplicates
3773 hose gdb.tar.Z link building. Remove RCS files from
3774 tconfig and xconfig. Add config files for sun386. Add
3775 a few odd files to OTHERS and HFILES.
3777 Mon Sep 10 21:20:24 1990 John Gilmore (gnu at cygint)
3779 * Makefile.dist: Pull solib.c to tconfig/sun?os4.
3780 Roll version number to 3.91.5. Make lint work in bindir.
3782 * README: Document cross-debugging and new file structure.
3784 * blockframe.c: Lint. Include "value.h" to declare read_register.
3785 (find_pc_partial_function): remove duplicate line.
3787 * command.h: Lint. Declare error_no_arg and dont_repeat.
3789 * tm-news.h: Remove inadvertently duplicated stuff.
3791 * mipsread.c: Remove cache_pc_function stuff, now done cleanly.
3792 Clean up usage of misc_function_type. Declare some CORE_ADDRs.
3794 * config.gdb: Allow `config.gdb host target' form. Clean
3795 up previous change that printed bogus messages when you just said
3798 * core.c: #include "command.h" for lint.
3801 * main.c: Remove some casts of enums. Lint.
3808 * printcmd.c (initialize_printcmd): Fix thinko in inspect cmd.
3810 * sparc-tdep.c (isannulled): Take instruction as parameter, don't
3811 read it from memory. This will allow us to save ptrace calls
3812 eventually. Changed caller single_step too.
3814 * sparc-xdep.c (fetch_inferior_registers): Avoid reading regs
3815 that we aren't going to use, saving many ptrace calls, especially
3816 when watchpointing or single stepping. Use some #define's for
3818 (store_inferior_registers): Ditto.
3819 (core_file_command): Use some #define's for constants.
3821 * tm-sparc.h: Add #define's for some register numbers, so we
3822 can eliminate the use of random constants in sparc-xdep.c.
3824 * stack.c (frame_command, print_frame_info, up_command,
3825 down_command) Remove frame_changed, since it
3826 causes a bug and doesn't seem to do anything useful. In some
3827 places it was used as a flag, in others as a stack level (?).
3829 * utils.c: Use MISSING_VPRINTF rather than HAVE_VPRINTF, so the
3830 default is to use the portable (vprintf) version rather than the
3832 * xm-news.h (MISSING_VPRINTF): Add.
3834 * valprint.c (val_print): Demangle fancy vtbl printouts. Lint.
3836 Sat Sep 8 00:24:12 1990 John Gilmore (gnu at cygint)
3838 * Remove stuff that forces -Bstatic linking of gdb, and warnings
3839 about linking debugged programs -Bstatic in the sun?os4 config
3840 files in tconfig and xconfig subdirectories.
3842 * main.c (main): Remove unreached exit(0) now that we exit
3845 * Create TODO file for online bug list. There are too many
3846 "little" bugs to keep track of on paper.
3848 * Change Projects file to refer to bug-gdb@cygnus.com
3849 rather than kingdon@ai.
3851 Fri Sep 7 23:35:15 1990 John Gilmore (gnu at cygint)
3853 * Makefile.dist (VERSION): 3.91.4 now.
3855 * symtab.c (init_misc_bunches): Rename from init_misc_functions.
3856 (condense_misc_bunches): Add sanity check that misc_count is
3857 the same as the number of symbols in the bunch.
3859 * coffread.c: rename init_misc_bunches. Pass an argument
3860 to condense_misc_bunches (a zero).
3862 * dbxread.c (partial_symbol_file_read): Call init_misc_bunches
3863 every time we are called; don't rely on our caller to do it.
3864 (add_file): Remove call to init_misc_bunches.
3866 * mipsread.c: Only warn, don't error, if unknown symbol types.
3867 This keeps an old gdb from falling on its face if it sees newly
3868 extended symbol info. Rename init_misc_bunches.
3870 Fri Sep 7 22:58:15 1990 John Gilmore (gnu at cygint)
3872 * Merge in changes from Per Bothner for DECstations and other
3873 MIPS stuff. The rest is Bothner speaking:
3875 The next message is a merger of Alessando Forin's mips port with
3876 mine. I've tried to use my good if biased judgment to get
3877 the best of both. It *does* need testing.
3879 Some of the changes are general, *not* mips-specific.
3882 Didn't believe in little-endian bit order.
3883 There are still inconsistencies about whether flags
3884 like BITS_BIG_ENDIAN are integer (#if ...) or
3885 boolean (#ifdef ...). I tried to paper over them.
3887 dbxread.c,coffread.c,mipsread.c,symtab.c,symtab.h:
3888 Moved some misc_function code that was common to
3889 {dbx,coff,mips}read.c to symtab.c.
3890 In the process, I think I cleaned things up a bit.
3891 At the same time, moved obsavestring and obconcat to symtab.c.
3894 Removed obsolete condense_addl_misc_bunches (use
3895 condense_misc_bunches(1) instead).
3898 Needed to include <sys/dir>, at least on DECstations.
3900 valops.c, mips-tdep.c, tm-mips.h:
3901 Added PUSH_ARGUMENTS macro to support funny argument-pushing
3902 conventions (when STACK_ALIGN is insufficient).
3903 Needed on mips, where doubles need 8-byte alignment,
3904 but ints only need 4.
3907 Removed cruft that was not being used.
3908 Merged in many fixes (most from Frank Yellin, fy@lucid.com).
3911 Print $ before register-names (I think that makes things a little
3913 Never print two instructions, even if one delays.
3914 Removed hex-disassemble set_cmd. (This is not mips-specific,
3915 so I think the argument is whether it is generally worthwhile or not.
3916 I'm inclined to think not, given how easy it is to
3917 convert between radixes in gdb.)
3920 This is basically Alessando's code.
3921 It doesn't use obstacks; I changed it to use obstacks
3922 in a few minor places where using malloc causes a
3923 memory leak. (Probably, more places could/should be changed.)
3924 I added record_misc_function where it was missing.
3925 In symbol_file_command and add_file_command, I tried
3926 to make the code consistent with more recent versions.
3927 Minor sylistic changes in parse_procedure.
3928 Make a .gdbinfo. psuedo-symbol point back to the real
3929 procedure symbol (using the isym field).
3932 This is basically from my port, but with a lot of details
3933 and a number of routines merged in from Alessando's version.
3934 I basically used my code "raw" backtrace (use heuristics
3935 from the actual code, rather than symbol table info) - though
3936 the idea is Alessandro's. I feel my code is a little cleaner
3937 here, particularly in being a little more flexible, such as being
3938 able to handle gcc-produced code (which it now can).
3939 It also doesn't do frame caching (which is not useful
3940 more recent gdb versions).
3941 I also used my code for push_/pop_dummy, more or less.
3942 I tried to incorporate AF's code for testing sigtramp
3943 while backtracing; I probably got it wrong.
3944 Added mips_print_register, which tries to scrunch as much
3945 information as possible on a screen...
3946 Removed the skip-prologue set_cmd. As with hex-disassemble (see
3947 under mips-pinsn.c), I don't see anything mips-specific here,
3948 and I don't see it being all that useful anyway.
3951 Added a $fp psuedo-reg distinct from $fp (nice for gcc).
3952 Use more register names (rather than hard-cases numbers).
3954 Thu Sep 6 18:33:15 1990 John Gilmore (gnu at cygint)
3956 * Hack up 3.90.11 changes:
3958 * Makefile.dist (depend): parameterize $(GCC).
3959 Add solib.c and solib.o.
3960 (readline): Fix vpath for both absolute or relative SRCDIR.
3962 * blockframe.c: Fix from Schaefer@asc.slb.com for shared libs.
3963 Also, let the part I didn't understand at least compile so
3964 I can test the rest. FIXME.
3966 * dbxread.c: Fix thinko using strcmp.
3967 (init_psymbol_list): declare static.
3968 (partial_symbol_file_open): Comment cleanups better, avoid
3969 cleaning up the string table since the caller will do that.
3970 Move the stat for mod time into symbol_file_command, temporarily.
3971 (There should be a mod time for each symbol file, eventually,
3972 to control its rereading. FIXME.)
3974 * infptrace.c (PT_WRITE_D): use same value as PT_WRITE_I for
3975 SunOS, which gives error for shared libs otherwise. (From
3976 Schaefer, probably FIXME needs work for portability.)
3978 * solib.c: Move #include "param.h" to work.
3979 Lowercase all the Uppercase Letters In the Messages.
3980 (find_solib): Clean up inferior_so_name for debug printouts.
3981 Allow no argument, to mean all shared libraries.
3983 * symmisc.c: include param.h to get CLEAR_SOLIB.
3985 Wed Sep 5 18:00:08 1990 John Gilmore (gnu at cygint)
3987 * Merge in Kingdon's changes from FSF: the diffs from 3.90.9
3988 to 3.90.11. ChangeLog entries below are from this.
3990 Wed Jun 13 09:17:39 1990 Jim Kingdon (kingdon at mole.ai.mit.edu)

3996 Tue Jun 12 16:15:26 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
4000 * Makefile.dist (gdb.tar.Z): Change linking of config so it works.
4002 Thu Jun 7 16:22:27 EDT 1990 Jay Fenlason (hack@ai.mit.edu)

4006 Mon Jun 4 18:12:31 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
4008 * m-sparc.h (REG_STRUCT_HAS_ADDR, STRUCT_ARG_SYM_GARBAGE):
4009 Put parens around gcc_p in expansion.
4011 Thu May 24 15:44:51 1990 Jim Kingdon (kingdon at mole.ai.mit.edu)
4013 * utils.c (lines_to_list): Return 10 if lines_per_page == 0.
4015 Wed May 23 16:36:04 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
4017 * Changes for Sun shared libraries:
4018 blockframe.c (find_pc_partial_function): If a non-text symbol
4019 is found, set *address = pc - FUNCTION_START_OFFSET.
4020 breakpoint.c (insert_breakpoints) [DISABLE_UNSETTABLE_BREAK]:
4021 Disable breakpoints instead of giving an error.
4022 source.c (select_source_symtab): Initialize cs_pst.
4023 symmisc.c: Call CLEAR_SOLIB if defined.
4024 symtab.h: Make text{low,high} CORE_ADDR not int.
4025 (psymtab): New field addr.
4027 dbxread.c: Move DECLARE_FILE_HEADERS outside functions.
4028 (record_misc_function): Give correct type for N_DATA symbols.
4029 (condense_misc_bunches): do "misc_function_count = j" regardless
4031 Take code which is shared between symbol_file_command and
4032 add_file_command and put it into partial_symbol_file_{open,read}.
4033 Split add_file_command into add_file_command and add_file.
4034 Make psymtab_to_symtab read in the string table if the file
4036 Two new parameters to read_dbx_symtab and start_psymtab.
4037 tm-sunos.h: New file.
4039 Tue May 22 17:43:03 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
4041 * infcmd.c: Change cont_command to continue_command and "cont"
4044 Mon May 21 14:41:41 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
4046 * breakpoint.c (enable_breakpoint): Get value of watchpoint.
4048 * defs.h [sparc]: Use <alloca.h> regardless of __GNUC__.
4050 * values.c (USE_STRUCT_CONVENTION): Check for structures of
4051 size 1,2,4,8 rather than size < 8.
4053 * dbxread.c (dbx_lookup_type): Do f->length *= 2 as many times
4054 as necessary, not just once.
4056 * sparc-opcode.h: Add a bunch of new opcodes which Sun as supports.
4058 Thu May 17 15:04:09 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
4060 * {t,x}m-sun386.h, sun386-xdep.c, {x,t}config/sun386
4062 * tm-news.h: Add CALL_DUMMY_*.
4064 * tm-68k.h: Remove duplicate comment at FRAME_FIND_SAVED_REGS.
4066 * config.gdb: In list_host, list_target, use ${i}, not $i.
4068 Tue May 15 21:27:12 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
4070 * source.c (find_source_lines) [BROKEN_LARGE_ALLOCA]: Use xmalloc.
4072 * sparc-opcode.h: Change all store floating-point state register
4073 instructions to have the right match & lose fields.
4075 Sat May 5 12:39:18 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
4077 * Makefile.dist: Move -I${srcdir} to GLOBAL_CFLAGS and pass
4079 config.gdb: If srcdir != ., create readline directory and
4080 copy a makefile into it.
4082 * wait.h, infrun.c: Change WRETCODE to WEXITSTATUS for
4083 consistency with POSIX.
4085 * breakpoint.c (bpstat_stop_status): Disable watchpoint
4086 when we exit its exp_valid_block.
4088 Tue Sep 4 11:46:46 1990 John Gilmore (gnu at cygint)
4090 * Makefile.dist: Bump version to 3.91.3.
4092 * Clean up handling of breakpoint commands (somewhat).
4093 Prompted by Tiemann bug report "cont 10" doesn't work any more.
4095 inferior.h: Add breakpoint_proceeded to inferior status struct
4096 and globals; save it and restore it.
4097 (clear_breakpoint_commands): Cleanup, remove old #define.
4099 infrun.c (clear_proceed_status): Set breakpoint_proceeded.
4100 (save_inferior_status, restore_inferior_status): handle it also.
4101 (proceed): Remove earlier code that set breakpoint_proceeded.
4102 It is now set only in clear_proceed_status.
4103 (clear_proceed_status): Cleanup, use bpstat_clear rather
4104 than clear_breakpoint_commands. No callers need the stop_bpstat
4105 between clear_proceed_status and proceed.
4107 infcmd.c: Add breakpoint_proceeded definition and comment.
4108 (cont_command, jump_command, signal_command): Move call to
4109 clear_proceed_status right next to call to proceed.
4111 breakpoint.c (bpstat_do_actions): Avoid clobbering our
4112 caller's argument while running down the chain of breakpoints.
4113 Use new variable "breakpoint_proceeded" to determine when
4114 a command that it executes moves the inferior past the
4116 (bpstat_clear): Handle NULL argument.
4117 (bpstat_clear_actions): Avoid useless call to
4118 breakpoint_auto_delete.
4119 (delete_breakpoint): Clean up bpstat's that are pointing to
4120 the deleted breakpoint from the stop_bpstat chain.
4121 (breakpoint_auto_delete): Simplify.
4123 * Clean up handling of EOF, error on stdin, etc. This was
4124 prompted by a network problem that caused gdb to go into an
4125 infinite loop filling up its malloc'd memory.
4127 main.c (return_to_top_level): Cleanup: call bpstat_clear_actions,
4128 not clear_breakpoints_commands, which is now gone.
4129 (main): If command_loop returns (e.g. from EOF on stdin), do
4130 a quit_command (looping back to command_loop if quit_command
4131 doesn't really quit).
4132 (command_loop): check result from command_line_input and
4133 exit if it returns NULL, rather than passing the NULL to
4135 (gdb_readline): Free malloc'd result space before returning
4138 * utils.c (query): Handle C-d to mean "yes", just as if the
4139 input was not a terminal. Also avoid infinite loop if EOF
4140 occurs in mid-input-line before newline. This allows
4141 query to be used at EOF on stdin with reasonable results.
4143 * infrun.c (proceed): Set breakpoint_proceeded.
4145 * values.c (value_as_long): Avoid infinite recursion for enums.
4146 (_initialize_values): Fix typo in help msg (kingdon).
4148 * Makefile.dist (RL_LIB): Use RL_LIB_DEP for dependencies,
4149 RL_LIB for linking. This allows -lreadline for linking
4150 and nothing for dependencies, once readline is a real library.
4152 * config.gdb: Jim Kingdon: give useful error message if the
4153 host or target type is not recognized.
4155 * defs.h (alloca): SPARC <alloca.h> does not declare alloca,
4156 it just defines it. Dumb, but deal with it.
4158 * Jim Kingdon suggests:
4159 in xconfig/sun3os4, CFLAGS should be XM_CFLAGS.
4161 Wed Aug 29 18:03:27 1990 John Gilmore (gnu at cygint)
4163 * Makefile.dist (VERSION): Bump version # to 3.91.2.
4165 * Clean up Bothner's changes.
4167 * blockframe.c (clear_pc_function_cache): New function.
4168 * blockframe.c: remake cache_pc_function_* static.
4169 * dbxread.c (symbol_file_command): remove references to
4170 cache_pc_function_* variables.
4171 * dbxread.c (read_struct_type): Use VOFFSET_STATIC.
4172 * printcmd.c: Avoid kludging a global variable (addressprint)
4173 to avoid printing the address of a string twice. Instead,
4174 pass the format letter 's' down low enough that it can be seen
4175 to avoid this problem.
4176 (print_formatted): Pass format arg to value_print.
4177 (restore_addressprint): Remove function.
4178 (do_examine): Avoid hacking addressprint, cleanups and such.
4179 (print_frame_args): Add a comment to a Bothner change.
4180 * symtab.h: define VOFFSET_STATIC and use it instead of "-1".
4181 * symmisc.c (free_all_symtabs): Call clear_pc_function_cache
4182 to wipe out the values cached in blockframe.c.
4183 * symtab.c (find_method): Add comment saying how big you must
4184 allocate to be "big enough". Per being terse again.
4185 * valprint.c (val_print): Handle format letter "s" to print
4186 strings without addresses. Add comment to vtbl printing code
4187 which casts with wild abandon. Rearrange reference-printing
4189 @0xaddr: value (print w/addressprint)
4190 value (print w/~addressprint)
4191 @0xaddr (parameter lists w/addressprint)
4192 or nothing (parameter lists w/o addressprint)
4194 Tue Aug 28 10:47:18 1990 John Gilmore (gnu at cygint)
4196 * Merge more changes from Per Bothner:
4198 Gdb's handling of TYPE_CODE_REF was so counter-C++ (and otherwise
4199 annoying) that I tried to improve it. Here are my suggestions.
4201 These patches all attempt to handle TYPE_CODE_REF (as in C++) better.
4204 Do automatic de-reference when taking the address of a reference.
4206 Don't deref_ref when printing parameter lists.
4208 More attempts at treating refernences properly.
4210 In val_print, if deref_ref==0, don't print dangling " = ".
4212 Add COERCE_REF macro, which de-references an REF.
4214 * Merge changes from Per Bothner:
4216 * Fixed (Sony news)-specific configuration problems.
4217 * Fixed other problems with using vanilla pcc and libc (enum problems;
4218 assumption that vsprintf exists).
4219 * Some major speed-ups (finc_pc_partial_function now caches a match;
4220 parsing avoids duplicate symbol_lookup calls).
4221 * Changed handling of baseclasses (no longer use baseclasses field
4222 of struct type, use the first n_baseclasses fields instead).
4223 * Various minor changes/fixes, most C++-related.
4226 Cache the most previous match from find_pc_partial_function.
4227 (Save both low and high ends of matching function's pc range.)
4228 This speeds up the loop of infrun.c:wait_for_inferior quite
4229 a bit, and makes step/next commands much zippier.
4231 Added an enum->int cast (otherwise, some compilers barf).
4233 No longer set baseclass offset to 0, since multiple
4234 inheritance now mostly works.
4235 Added a number of casts, to shut up compiler warnings
4236 (after stabs where made enums, not ints).
4237 When discarding a symbol table (in symbol_file_command),
4238 must clear the cache introduced in blockframe.c.
4239 Don't convert $vtbl_ptr_type to vtbl any more.
4240 Get rid of TYPE_BASECLASEES and baseclass_vec (see also symtab.h).
4241 Mask off sign bit emitted by g++ for virtual table offset.
4242 Set voffset to -1 (not 1) for static member functions.
4244 Changed parsing/lexing of names to avoid doing symbol lookup twice
4245 (once when lexing to determine symbol class, once for real).
4246 Now only call symbol_lookup once. Fields of 'this' win especially big.
4248 Subpress printing addr twice in the case of 'x/s addr'.
4250 lookup_basetype_type is no longer used.
4251 Add find_methods as recursive helper function to decode_line_1.
4252 This allows multiple inheritance to work.
4253 Also, once one or more matches has been found, do not look in
4254 base-classes. (Baseclass methods would be overridden, anyway.)
4256 Removed baseclasses array in struct type.
4257 Instead of using baseclasses[i], use fields[i-1].
4258 Added virtual_field_bits[i] to indicate if the i'th baseclass is virtual.
4259 Changed sign convention of voffset (previous was inconsistent).
4261 Some macros (CALL_DUMMY and relatives) were missing. Put them back.
4263 Used to assume existence of vsprintf. Re-written to not need it
4264 if HAVE_VPRINTF is undefined.
4266 typecmp was too pessimistic. Made it less so.
4268 Don't print space after address.
4269 If vtable points to a misc symbol (with 0 offset), print it,
4270 since that indicates the actual class of the object.
4271 Changed ype_print_derivation_info to use new inheritance
4272 scheme (without baseclasses vector).
4274 In value_primitive_field, fixed some bugs left over from previous set of fixes.
4275 Also, changes needed because TYPE_BASECLASSES were removed.
4277 REGISTER_U_ADDR didn't work for PC. Rewrote to use an array.
4279 Tue Aug 21 20:08:54 1990 John Gilmore (gnu at cygint)
4282 If there is no path set, and the symbols don't indicate what directory
4283 a file was compiled in, look in the current directory. But either
4284 a path or a known compilation directory will prevent this.
4287 Three independent bug fixes:
4288 * Remove the #if 0 block that breaks some stuff.
4289 * SunOS 4.1 fixed the promoted-parameter-wrong-addr bug in Sun C;
4290 adapt gdb to either SunOS 4.0.* or 4.1.
4291 * MAX_OF_TYPE and MIN_OF_TYPE thinko. By tedg@sun, I think.
4294 Instantiate the class T when looking for methods in it. (Tiemann@sun)
4297 (type_print) Demangle the name being printed.
4298 (type_print_base) Handle botched demangling without coredump (tiemann).
4301 (check_stub_method): Document routine.
4302 (tiemann) fix bug for no-arg functions
4303 Avoid clobbering beyond end of malloc'd storage.
4304 Terminate the argument list properly.
4306 Sat Aug 18 01:29:59 1990 Per Bothner (bothner@cs.wisc.edu)
4308 * Changes merged by John Gilmore:
4311 In breakpoint_1, use new print_address_symbolic instead
4312 of find_pc_partial_function. (This forces use of assembler-level
4313 addresses, and avoids misleading non-mangled source-level names.)
4315 Generalize ansi argument such that -1 means skip arglist totally.
4316 Removed global variable print_ansi_qualifiers (which made
4317 code non-reentrant), in favor of extra explicit arguments
4318 to internal routines.
4320 Add new helper function print_address_symbolic.
4321 Use find_pc_misc_function instead of find_pc_partial_function
4322 (since we want assembler-level symbols here).
4324 Print unknown function as just "f (...)", not "f (...) (...)".
4325 Use new fputs_demangled explicitly.
4327 Fixed a typing violation (problem: value.h cannot be imported
4328 without renaming many variable in this file).
4329 lookup_symbol: If no matching misc_func, look for a C++-mangled name.
4330 decode_line_1: Moved forward some never-reached code.
4331 Made decode_line_2 skip function prologues correctly.
4333 fputs_filtered should not demangle by default.
4334 Add new fputs_demangled to demangle on demand..
4336 Change value_struct_elt to use value_primitive_field (using recursive
4337 utility function search_struct_field). This allows foo.bar to work
4338 for multiple inheritance (so far only for data fields).
4339 Change check_field in the same way (recursive helper function
4340 to support multiple inheritance).
4341 (Note: there are more of these problems that I haven't fixed.
4342 Any code that says TYPE_BASECLASS (t, 1) is probably wrong.)
4343 value_of_this: 'this' symbol name is now just "this", note "$this".
4345 Don't print static members.
4346 Avoid printing "members of <type>" if there are none.
4347 Simplified type_print_derivation_info by merging duplicate code.
4348 Remove useless blank lines in type_print_base (ptype command).
4350 Added declaration of new routine value_primitive_field.
4352 Added value_primitive_field which is generalized version of
4353 value_field that can handle multiple inheritance (non-zero offsets etc).
4354 Re-implemented value_field to call value_primitive_field.
4356 Fri Aug 17 23:33:44 1990 John Gilmore (gnu at cygint)
4358 * infcmd.c -- insert else to avoid 'delete env' coredump when you
4359 delete the whole environment. Karl Berry reported the bug.
4360 * source.c - fix openp to avoid //'s in filenames, which
4361 trigger an Emacs bug causing it to not be able to find files
4362 when running gdb in a window.
4363 * dbxread.c - zap the #if 0 that botches the add-file code.
4364 It seems to work a lot better without all the code commented out.
4366 Fri Jul 20 16:58:46 1990 John Gilmore (gnu at cygnus.com)
4368 * Merge Tiemann's and Ted Goldstein's changes, detailed below,
4371 Tue Jul 17 19:34:33 1990 Ted Goldstein (tedg at golem)
4373 * Makefile - added a ${CFLAGS} to a couple of entries,
4374 added remote-sa.sparc.c
4375 * added remote.sa-sparc.c, a modification of remote.c
4376 which conducts a dialog directly with the SparcStation prom.
4377 * breakpoint.c, infrun.c, sparcdep.c added
4378 remote_insert_breakpoint(), and remote_remove_breakpoint()
4379 to breakpoint.c instead of directly writing breakpoint instructions.
4380 * sparcdep.c on remote_debugging,there is no need
4381 to remove signle step breakpoint instructions.
4382 * main.c added "-epoch" flag and "int epoch_interface" to main.c
4384 * printcmd.c - epoch interface sends lisp expressions to open up
4385 epoch windows on inspection.
4386 * valprint.c - added arrayprint, and addressprint and made adding
4387 format controls easier
4388 * wait.h added a couple of undef's because we were getting
4389 complaints about WSTOPSIG and WTERMSIG begin redefined.
4392 Wed Jul 4 05:27:51 1990 Michael Tiemann (tiemann at masham)
4394 * symtab.c (decode_line_1): Add support for handling method stubs
4395 in the type information.
4397 Tue Jul 3 09:39:18 1990 Michael Tiemann (tiemann at masham)
4399 * values.c (baseclass_addr): Run loop from INDEX+1 to
4400 N_BASECLASSES; otherwise, we can still get into a loop.
4401 @@ This should be restructured to use a cleaner search strategy.
4403 Sun Jul 1 12:28:51 1990 Michael Tiemann (tiemann at masham)
4405 * dbxread.c (define_symbol,read_type): Grok GNU C++'s new
4406 abbreviation "Tt" for tags which have the same name as their
4409 Fri Jun 29 01:03:46 1990 Michael Tiemann (tiemann at masham)
4411 * symtab.c (list_symbols): add ability to set breakpoints on all
4412 the functions which match a particular regular expression.
4414 Tue Jun 26 04:26:29 1990 Michael Tiemann (tiemann at masham)
4416 * cplus-dem.c (cplus_demangle): New parameter ANSI says whether we
4417 should print ANSI qualifiers (such as `const' and `volatile').
4418 All callers changed to call with ANSI == 1, except from
4419 `check_method_stub', which uses old-style syntax.
4421 * symseg.h (struct fn_field): Remove unneccessary `args' field.
4422 * symtab.h (TYPE_FN_FIELD_ARGS): Redefined.
4424 * values.c (check_stub_method): New function.
4426 * cplus-dem.c (do_type): Handle "long long" (encoded as 'x').
4428 * dbxread.c (read_type): Handle new GNU C++ method type stubs.
4429 * valprint (type_print_base): Ditto.
4431 * symtab.c (gdb_mangle_typename): New function.
4433 Tue Jun 5 00:18:43 1990 Michael Tiemann (tiemann at gzilla)
4435 * breakpoint.c (catch_command): New function. Provides a
4436 mechanism to set breakpoints based on catch clauses.
4437 (disable_catch): Similar, but disables breakpoints on catch
4439 (delete_catch): Similar, but deleted breakpoints on catch clauses.
4441 Sun Jun 3 22:54:08 1990 Michael Tiemann (tiemann at gzilla)
4443 * blockframe.c (blockvector_for_pc): New function.
4444 * blockframe.c (block_for_pc): Changed to call
4445 `blockvector_for_pc' and get the block itself.
4447 * stack.c (catch_info): New function. Prints info about
4448 exceptions which can be caught in the current frame.
4449 * stack.c (print_frame_label_vars): New function. Similar to
4450 `print_frame_local_vars'.
4451 * stack.c (print_block_frame_labels): Prints out labels that are
4452 defined in this frame. These labels are exceptions that can be
4455 * dbxread.c: Updated to handle N_CATCH symtab types.
4457 Thu May 3 22:10:00 1990 Michael Tiemann (tiemann at teacake)
4459 * valprint.c (everywhere): TYPE_NAME (TYPE) no longer comes in the
4460 form "struct ..." for GNU C++. Don't flush any part of TYPE_NAME
4461 when printing the type.
4463 Wed May 2 22:43:04 1990 Michael Tiemann (tiemann at teacake)
4465 * valprint.c (val_print): Use `baseclass_addr' to access the
4466 baseclasses pointed to via the derived class object at VALADDR.
4468 * values.c (baseclass_addr): New function. Casts derived pointers
4469 to baseclass pointers taking virtual baseclasses and multiple
4470 inheritance into account.
4472 Sat May 5 12:39:18 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
4476 Fri May 4 12:12:55 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
4478 * breakpoint.c (watch_command, bpstat_stop_status): Deal with
4479 exp_valid_block field correctly.
4481 * infrun.c (wait_for_inferior): When checking "don't even think
4482 about breakpoints" if stop_signal == SIGTRAP && trap_expected,
4483 also check step_resume_breakpoint.
4484 Insert breakpoints and continue (not step) if
4485 step_resume_break_address != NULL, even if another_trap.
4486 If trap_expected and we enter sigtramp, then set up a
4488 If trap_expected is set when we hit the step_resume_break,
4490 When calling resume and trap_expected says tell resume to step
4491 (2 places), also check step_resume_break_address.
4493 * infrun.c (wait_for_inferior): Don't set
4494 prev_{pc,sp,func_{start,name}} before calling wait ().
4495 Do set them after exiting loop.
4496 Move their declarations outside functions.
4497 (start_inferior): Initialize them.
