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

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

1290 * dbxread.c (read_dbx_symtab): Allow N_SOL to cleanly take us back
1291 to the main file, as well as to include files. Also, put global
1292 functions into the global psymtab, to make "i fun" work.
1293 (end_psymtab): Free named symtabs and psymtabs for a file, once a
1294 new psymtab for it has been read.
1295 * coffread.c (end_psymtab): Free named symtabs and psymtabs for
1296 a file, once a new symtab has been read for it.
1297 * mipsread.c: FIXME. We need to do the same for MIPS, but it
1298 looks harder to determine the top-level block before it's been
1299 queued to the psymtab list.
1301 * symfile.c (symbol_file_add): Use filtered printing and wrap it.
1302 If we have wiped out any old symbol tables, clean up at end of

1318 static psymbols list.
1319 (types_info): Restore this function from its untimely #if 0.

1341 is the first symbol read, even if not mainline.
1342 (dbx_psymtab_to_symtab): symfile might be zero, cope.
1343 * exec.c (exec_ops): Add_syms_addr is valid in our tvec.
1344 (set_section_command): New command ("section xxx yyy" -- should
1345 be renamed to "set section xxx yyy" FIXME) which sets the
1346 base address of a section of the exec file, overriding the
1347 virtual address that BFD reports.
1349 Fri Apr 5 17:14:39 1991 John Gilmore (gnu at cygint.cygnus.com)
1351 * exec.c: Add add_syms_addr_command to exec_ops, so you can

1356 * tm-i386v.h (FLOAT_INFO): Don't define it, since the code
1357 for printing the float info is host-dependent, not
1358 target-dependent. FIXME.
1359 * i386-pinsn.c: Move #includes to top, remove useless ones.
1360 * i386-tdep.c: Don't bother including <.../reg.h> since we
1361 don't use it (and it doesn't exist on host systems).
1363 * ieee-float.c (ieee_extended_to_double): Convert NaN to Inf.
1364 Convert negative numbers properly.
1365 (ieee_test): Make numbers really random; fix format arg.
1367 * infcmd.c (attach_command, detach_command): Don't repeat on CR.
1368 * core.c (core_detach): Unpush core_ops, which might not be on
1369 top. We used to just pop the top, which broke things. Don't
1370 need dont_repeat() any more.
1371 (core_file_command): Psst! Don't repeat it.
1372 * remote-nindy.c (nindy_detach): Don't need dont_repeat() now.
1373 * expprint.c (print_subexp): Avoid switch fallthru on
1374 BINOP_ASSIGN_MODIFY, so we can print += and such.
1375 * frame.h: Fix typo.
1376 * inflow.c (kill_command): After killing inferior, print our
1377 current frame in the core file, if we have one.
1378 (generic_mourn_inferior): When inferior dies, either select
1379 the current frame (in the new target, e.g. core file), or
1380 set both the current and selected frames to NULL.
1382 Changes from Peter Schauer.
1384 * infptrace.c: Avoid <sys/ptrace.h> on USG.
1386 * Make all file names fit in 14 characters (sigh and damn!):
1387 mv hp300hpux-xdep.c hp300ux-xdep.c
1388 mv symmetry-xdep.c symm-xdep.c
1389 mv symmetry-tdep.c symm-tdep.c

1391 mv tm-vxworks960.h tm-vx960.h
1392 mv tm-vxworks68.h tm-vx68.h
1393 mv Makefile.srcdir Makefile.sdir
1394 mv gdb-int.texinfo gdbint.texinfo
1395 mv remote-sa.m68k.shar rem-m68k.shar
1396 mv remote-multi.shar rem-multi.shar
1397 * Makefile.dist, README, config.gdb, convex-pinsn.c,
1398 tconfig/symmetry, tconfig/vxworks960, tconfig/vxworks68,
1399 xconfig/hp300hpux, xconfig/symmetry: Change names to shorter
1402 * command.c (user_info_1, user_info): New command for listing
1403 the user-defined commands.
1405 Wed Apr 3 15:00:26 1991 John Gilmore (gnu at cygint.cygnus.com)
1407 * dbxread.c (really_free_pendings): Clear file_symbols
1408 and global_symbols after freeing them; otherwise, running
1409 this function twice (if it appears twice on the cleanup
1410 chain), we try to free things twice.
1412 * dbxread.c (read_dbx_symtab): Calculate end_of_text_addr
1413 based on text_addr (the address of text in core), not on addr (the
1414 offset between text in the .o file and in core). This change
1415 is from Peter Schauer.
1417 * main.c: Define ALL_CLEANUPS as a cast of zero.
1418 (return_to_top_level): Use it.
1419 (main): Do all cleanups after each command run as part
1420 of the gdb startup sequence. Also do all cleanups before
1421 entering the command loop, and every time we exit the command
1422 loop and reenter. Before, the cleanups from the startup sequence
1423 were being left undone until the first error!
1424 (command_loop): Rename do_nothing cleanup to command_loop_marker
1425 so we can see it easily when examining the cleanup chain.
1426 (init_signals): Add another do_nothing for signal handling.
1427 (quit_command): Only try to kill target if it has execution.
1428 Problems in the target stack got us into a state where
1429 inferior_pid was nonzero but none of the targets had execution.
1430 In this state you couldn't exit gdb.
1432 * dbxread.c: Two changes from Peter Schauer.
1433 (echo_command): Fflush output after an echo command.
1434 (show_history): Pass all args to cmd_show_list.
1436 * utils.c (init_malloc): Call mtrace to turn on tracing
1437 if the environment variable MALLOC_TRACE is set to a file name.
1438 * mtrace.c: Add source file which provides a log of every malloc,
1439 free, and realloc to a trace file.
1440 * mtrace.awk: Add source file which analyzes the trace file.
1441 * Makefile.dist (GNU_MALLOC, MALLOCSRC): Add mtrace.{c,o,awk}.
1442 (VERSION): Roll to 3.94.3.
1444 * breakpoint.c (breakpoint_1): Add a space to "i watch" output.
1445 (check_duplicates): Don't bother with watchpoints.
1446 (set_raw_breakpoint): Comment about danger of this routine.
1447 (watch_command): Parse and eval all args before calling
1450 * solib.c (find_solib): Avoid error in referencing memory to
1451 see if any more shared libraries have been added. This is
1452 particularly useful if the target has terminated. Bug reported
1455 Changes from Peter Schauer <pesrem@regent.e-technik.tu-muenchen.de>
1456 in bringing up 3.94.2 on the Sun-3.
1458 * Makefile.dist: Include CFLAGS in rule for cplus-dem.o.
1459 * breakpoint.c (enable_breakpoint): Check for valid watchpoint
1460 expression (in scope) before reenabling watchpoint.
1461 * signame.c (init_sigs): Add missing declaration of i, fix
1462 sys_siglist declaration.
1463 * source.c (list_command): Fixed range computation to use
1465 * stack.c (backtrace_command): Do not allow command if target has
1466 no stack, print informative error message.
1467 * target.c (target_command): Do not write into command line
1468 because this fails if the target command is used in a user defined
1469 command. [This change was enhanced by gnu to support any-
1470 unique-prefix matching on target names.]
1471 * valops.c (value_struct_elt): Avoid infinite loop on an
1472 erroneous attempt to print the member of function (try p main.p).
1474 Mon Apr 1 17:05:45 1991 John Gilmore (gnu at cygint.cygnus.com)
1476 * expread.y (name_no_typename): Avoid reduce/reduce errors
1477 caused by ambiguity in handling NAME_OR_INT and NAME_OR_UINT.
1478 Since the GDB parser really doesn't use name_no_typename in a
1479 name-only context, the parser can't tell the diff between
1480 names and numbers here. Avoid allowing a name_no_typename
1481 to be a NAME_OR_*INT to resolve the conflict.
1483 Sun Mar 31 20:12:07 1991 John Gilmore (gnu at cygint.cygnus.com)
1485 Bugfixes from Mark Fox (markf@wrs.com) (test=testField.c):
1487 * valprint.c (val_print_fields): bitfield printing didn't handle
1488 byte order. Indirect through a few more fns to cope.
1490 * values.c (modify_field): also cope with byte order.
1492 Sat Mar 23 10:02:21 1991 John Gilmore (gnu at cygint.cygnus.com)
1494 Cleanup for release 3.94.2:
1496 * Makefile.dist: Pull REMOTE_OBS. Fix saber includes for BFD
1497 include files. Roll version to 3.94.2.
1499 * coffread.c (init_stringtab): Read length into unsigned char
1500 array before swapping; don't assume 32-bit longs.
1502 * target.c (target_info): Don't bother with get_sym_file, just use
1503 the symfile global variable.
1504 * symtab.h, symfile.c (get_sym_file): Delete it.
1506 * dbxread.c (dbx_symfile_init): Don't depend on long == 4 bytes.
1507 (define_symbol): Set symbol line number to 0 if not gcc-compiled.
1508 (read_type): Replace one more error() with complain().
1510 * mipsread.c (parse_partial_symbols): Replace printf with complain.
1512 * i960-tdep.c: Fix copyright attribution.
1514 * config.gdb: Quote all backquotes in doublequotes. You can
1515 quote me on that. BSD 4.4 shell found this one.
1517 * infptrace.c (throughout): The third argument to ptrace is an
1520 * infrun.c (wait_for_inferior): When program has terminated, we
1521 have to call target_terminal_ours before we pop that target off
1522 the stack (e.g. before a call to target_kill or
1523 target_mourn_inferior). This fixes problem where a program
1524 terminates, then GDB stops for (tty output) and you have to type
1525 "fg" to the shell to resume it. FIXME: This code for what to
1526 do after termination really should be in normal_stop instead.
1528 * gdbcore.h (read_memory_check): Change declaration; it changed
1531 * terminal.h: Include <sgtty.h> before <sys/ioctl.h>, since in BSD
1532 4.4 prereleases, this avoids a bug in their sgtty compatability
1534 * remote.c: Use terminal.h rather than hand-rolling the same.
1536 * signame.c, signame.h (psignal): Arg is unsigned, not int.
1537 * utils.c (strsave, strstr): Fix arg types.
1538 * valprint.c (val_print): lint
1540 MIPS symbol table support from Per Bothner:
1542 * symfile.c (symtab_fns): Remove initializer table that needs to
1543 be hacked for each new symbol file format supported.
1544 (add_symtab_fns): New function, chains symbol table
1545 handlers into the global list.
1546 (symfile_init): Search this list.
1547 * symfile.h: Add next pointer, declare add_symtab_fns.
1548 * coffread.c (_initialize_coffread): Call add_symtab_fns.
1549 * dbxread.c (_initialize_dbxread): Call add_symtab_fns.
1551 * mipsread.c (psymtab_to_symtab_1): return void instead of (struct
1552 symbol *). Thus, we no longer need the hack to trash
1553 pst->filename. Good, since that hack confused code in symfile.c!
1555 (reorder_symtabs, destroy_all_symtabs): Removed static
1556 all_symtabs, which was used to qsort symtabs in reorder_symtabs.
1557 Instead, the latter now uses a temporary array (stack-allocated
1558 from an obstack, and then freed).
1560 (parse_symbol): Added a hack to fix up BLOCK_{START,END} if they
1561 haven't been set in the outermost stBlock of a procedure. This was
1562 a problem with f77 binaries on Ultrix 4.?.
1564 (new_symtab, new_symbol, new_type): Continue changing code to use
1565 obstacks more and otherwise conform to dbxread internal style.
1566 Made the free_code of symtabs be free_linetable (as in dbxread)
1567 instead of free_contents. This implies memory leaks when reading
1568 a new symbol table, until the conversion is finished. Did change
1569 (struct symbol) and (struct type) to be allocated on the
1570 symbol_obstack. Blocks and blockvectors are among the things
1573 * mipsread.c (parse_partial_symbols, parse_fdr): It hasn't been
1574 tested much, but it solved one problem (reported by Meissner), and
1575 cleans up some other things. The problem happened when an
1576 included file contains actual code (functions) and not just
1577 definitions. The mips coff is a little inconvenient there, since
1578 it may cause a procedure to be mapped to the wrong psymtab.
1580 * mips-tdep.c (heuristic_proc_desc): Minor cleanup.
1581 * mips-xdep.c (fetch_core_registers): Minor cleanup. FIXME,
1582 this will need work for the new core paradigm.
1584 Opcode patches from the net:
1586 * mips-opcode.h: fix incorrect disassembly of the mfc1, cfc1, and
1587 ctc1 instructions. Also, the cvt.d.w and cvt.s.w instructions were
1588 missing altogether - they are added here. From Bruce Bauman.
1589 * mips-opcode.h: The low mask for C0 instructions was too small.
1590 From Garrett Lau. I modified the fix to check the entire 32-bit
1593 * ns32k-opcode.h: Fix opcodes for deiw and deid. From Bruce
1596 Thu Mar 21 12:56:46 1991 John Gilmore (gnu at cygint.cygnus.com)
1598 Roll in changes from Per Bothner (Tue, 25 Sep 90 11:11:04):
1600 * dbxread.c (read_type): Pointer subtraction (value_sub in
1601 valarith.c) sometimes failed because the types of the
1602 pointers being subtracted were not identical.
1603 These differed because dbxread.c was allocating pointer types
1604 using dbx_alloc_type+smash_to_pointer_type instead of
1605 lookup_pointer_type. I failed to find a justification for the
1606 former, so I changed it to use the latter. Similarly, I
1607 replaced smash_to_function_type by lookup_function_type,
1608 and smash_to_reference_type by lookup_reference_type.
1610 * mipsread.c (parse_symbol, upgrade_type, parse_procedure,
1611 _initialize_mipsread): corresponding changes.
1613 * symtab.c (smash_to_{pointer,reference,function}_type): eliminate.
1615 * source.c (mod_path): Do tilde_expand on each component of the path,
1616 rather than on the (list of) paths as a whole.
1617 (print_source_lines): Set first_line_listed in addition to
1618 current_source_symtab and current_source_line. If the source was
1619 not findable, after a "dir" command to fix the problem,
1620 a "list" would get the wrong lines.
1622 While I was there... (gnu):
1624 * dbxread.c (read_type): Change error to complaint.
1626 Thu Mar 21 12:56:46 1991 John Gilmore (gnu at cygint.cygnus.com)
1628 First attempt at detailed understanding of symbol table memory alloc.
1630 * dbxread.c (dbx_symfile_read): Free our string table if we
1631 aren't the mainline. Free the "info" struct since we're done with
1633 (init_psymbol_list): Free any previously allocated psymbol lists.
1634 (): FIXME: Should realloc-down the psymbol lists when done reading
1635 the main symbol file?
1637 * symmisc.c (free_symtab): Free fullname field too.
1639 * xm-hp300hpux.h (USG): #undef then #define so Makefile can -D.
1640 (REGISTER_ADDR): Make result type unsigned int.
1642 * xconfig/{i386*,hp300hpux,altosgas,altos}: All config files that
1643 define REGEX must also define REGEX1 (its dependency).
1645 Tue Mar 19 21:28:57 1991 John Gilmore (gnu at cygint.cygnus.com)
1647 * tconfig/i960: No longer works, points you at vxworks960 or
1650 * xgdb.c, XGDB-README: Remove file. Users can get the much
1652 * Makefile.dist: Remove all trace of xgdb.
1654 * breakpoint.c (breakpoint_1): Pass demangle arg to
1655 print_address_symbolic.
1656 (clear_breakpoints): Remove unused function.
1657 (breakpoint_re_set_one): Guts of breakpoint_re_set.
1658 (breakpoint_re_set): Use catch_errors to do them all anyway.
1660 * gdb-int.texinfo (Host versus Target): Add section on what is
1661 a "host" feature versus what is a "target" feature.
1663 * infcmd.c (path_command, path_info): Handle the PATH variable
1664 (object search path) as conveniently as the source search path.
1665 * environ.c (set_in_environ): Set some vars in GDB's environment,
1666 in addition to the child's. PATH, G960BASE, G960BIN for starters.
1667 * source.c (mod_path): New function, from guts of
1668 directory_command, modifies a path. Used by path_command.
1669 (directory_command): Call it.
1670 * defs.h (strsave): Declare.
1672 * utils.c (sevenbit_strings): Add new printing option.
1673 (printchar): Use it.
1674 (strsave): Provide this handy helper routine.
1675 (set_width_command): Rename set_screen_width_command.
1676 (_initialize_utils): "set screen-width" => "set width";
1677 "set screen-height" => "set height"; add sevenbit-strings.
1679 * infcmd.c (do_registers_info): Print floating point registers
1680 in raw hex as well as float format, regardless of whether it is
1681 a "virtual" convertible register.
1682 * tm-sparc.h (PRINT_REGISTER_HOOK): Print every pair of float
1683 regs as a double, just in case it's being used that way.
1684 * values.c (unpack_long): Comment on array/function coercion.
1685 (unpack_double): Argument is in target byte order now. For
1686 integer arguments, just call unpack_long and float the result.
1687 * m68k-tdep.c: include defs.h for "const" handling.
1688 * remote-nindy.c: Use ieee-float stuff.
1689 (nindy_fetch_registers): Unpack double regs to host double, then
1691 (nindy_store_registers): Pack extendeds to host double, flip
1692 around by misusing unpack_double, send as target double.
1694 * tm-vxworks68.h (FRAME_CHAIN): Handle current frame pointer of
1695 zero, as when stopped at the first instruction of a process.
1697 * blockframe.c: Fix filename in comment (param.h => tm.h).
1698 * sparc-tdep.c (skip_prologue): More explicit nudging comments.
1699 * tm-68k.h: Fix typos.
1701 Fri Mar 15 01:09:34 1991 John Gilmore (gnu at cygint.cygnus.com)
1703 Changes from a bringup on the DEC Vax under Ultrix 4.0.
1705 * coredep.c (fetch_core_registers): Pass end-address of register
1706 section to register_addr as expected. Don't call supply_register
1707 if we'd just pass it garbage.
1709 * dbxread.c (read_dbx_symtab): Skip N_NSYMS on Ultrix.
1711 * exec.c (xfer_memory): Use boolean xfer_fn result, not int.
1713 * target.c (push_target, target_info): Cast enums to int for < or
1716 * stack.c (print_frame_info): Identify source file & line
1717 even if we can't print it.
1719 * xm-vax.h (MISSING_VPRINTF): No longer missing in Ultrix V4.0.
1721 Sat Mar 9 10:08:20 1991 John Gilmore (gnu at cygint.cygnus.com)
1723 Clean up IEEE floating point support.
1725 * ieee-float.h: New file.
1726 * ieee-float.c: Write real routines to convert between host
1727 doubles and various target IEEE extendeds.
1728 * m68k-xdep.c: Eliminate assembler code for extended floats.
1729 * xconfig/{3b1,altos,altosgas,hp300bsd,isi,news,news1000,sun2os3,
1730 sun2os4,sun3,sun3os3,sun3os4}: Eliminate use of m68k-xdep.o.
1731 * tm-i960.h, tm-68k.h (REGISTER_CONVERT_TO_VIRTUAL,
1732 REGISTER_CONVERT_TO_RAW): Use ieee_extended_to_double and
1733 double_to_ieee_extended.
1734 * i960-tdep.c: Define ext_format_i960.
1735 * m68k-tdep.c: Define ext_format_68881.
1736 * sparc-tdep.c: Define ext_format_sparc, though unused.
1737 * Makefile.dist (HFILES): Add ieee-float.h.
1738 * inftarg.c: #include "ieee-float.h" for the REGISTER_CONVERT
1741 Obsolete the "coffstrip" program in favor of using BFD's strip.
1743 * nindy-share/coffstrip.c: Remove file.
1744 * nindy-share/nindy.c (coffstrip): Routine to run bfd_strip.
1745 * Makefile.dist: Remove references to nindy-share/coffstrip.c.
1746 * tconfig/nindy960: Remove reference to coffstrip.o.
1748 * Makefile.dist: Roll version number to 3.94.1 (not yet final).
1750 Wed Mar 6 09:56:45 1991 John Gilmore (gnu at cygint.cygnus.com)
1752 * symfile.h: Add symfile_bfd, common between dbxread and coffread.
1753 * dbxread.c: Remove static symfile_bfd.
1754 * infcmd.c (do_registers_info): Add PRINT_REGISTER_HOOK, though
1756 * inftarg.c (child_detach): Pop the child_ops vector if the
1757 detach is successful.
1758 * remote-nindy.c (nindy_create_inferior): Don't push a new
1759 nindy_ops since nindy uses the same one for execution and memory
1761 * core.c (core_ops): Use child_attach and child_create_inferior
1762 rather than default attach and create_inferior functions.
1764 Handle floating point registers in core files.
1766 * sparc-xdep.c (fetch_core_registers): Rewrite for float support.
1767 * sun3-xdep.c (fetch_core_registers): Rewrite for float support.
1768 This version untested since BFD doesn't yet support sun3 core
1770 * hp300hpux-xdep.c: Rewrite fetch_core_registers to new calling
1771 conventions. Fix comments and style. This version has not
1772 been compiled yet, since we have no HP inhouse.
1773 * core.c (get_core_registers): Look for two sections, ".reg"
1774 and ".reg2", and pass both to fetch_core_registers sequentially.
1776 Revise directory path yet again.
1778 * source.c (forget_cached_source_info): Not static any more.
1779 (init_source_path): New default source path is "$cdir:$cwd".
1780 (dir_command): Handle variable arguments ($cdir, $cwd).
1781 (source_info): Print "Compilation directory" rather than
1782 "Originally compiled in" to remind people of $cdir.
1783 (openp): If the path contains $cwd, use current directory.
1784 (open_source_file): If compilation directory is known, replace
1785 first $cdir in path with the compilation directory.
1786 (print_source_lines): Even if we can't print the lines, set the
1787 current symtab and line for future commands like "info source" or
1788 "breakpoint". Also, error message now contains the file name,
1789 line number, and file access error message.
1790 (_initialize_source): Fix help text to describe changes.
1791 * main.c (cd_command): Forget cached source info when we chdir.
1792 * utils.c (strstr): Add simple implementation.
1794 Tue Mar 5 01:41:40 1991 John Gilmore (gnu at fowanton.cygnus.com)
1796 * coffread.c (read_one_sym, init_linetable, init_stringtab):
1797 Byte-swap COFF symbol tables if necessary when reading them in.
1798 Use complain() to replace error message in one spot. Needs
1799 corresponding change in bfd/coff-code.h to make some symbol
1800 swapping routines non-static.
1802 Mon Mar 4 00:53:40 1991 John Gilmore (gnu at cygint.cygnus.com)
1804 Merge changes from Eirik Fuller, for UTek.
1806 * defs.h (errno): Add declaration.
1807 * altos-xdep.c, arm-xdep.c, convex-xdep.c, gould-xdep.c,
1808 hp300hpux-xdep.c, infrun.c, inflow.c, infptrace.c, i386-tdep.c,
1809 i386-xdep.c, pyr-xdep.c, mips-xdep.c, remote-eb.c, remote-nindy.c,
1810 remote-vx.c, source.c, standalone.c, stuff.c, sun386-xdep.c,
1811 symmetry-tdep.c, symmetry-xdep.c, umax-xdep.c, utils.c: Eliminate
1812 declarations of errno.
1814 * remote-eb.c: Define B19200 and B38400 as EXTA and EXTB.
1816 * remote-vx.c: Include <sys/time.h> for UTek; Sun gets it via
1817 <rpc/rpc.h> and <rpc/types.h>.
1819 Sat Mar 2 15:47:55 1991 John Gilmore (gnu at cygint.cygnus.com)
1821 * i960-tdep.c (examine_prologue): Add new argument limit,
1822 which stops the scan at the end of the prologue, or at the PC.
1823 This fixes a problem where it walks down into the code for the
1824 user's statements if that code looks like function prologues.
1825 Mark Fox and I have been bouncing this code back and forth, making
1826 small changes to it. Callers changed to match.
1828 Tue Feb 26 01:47:07 1991 Cygnus John Gilmore (cygnus at yuba)
1830 Cleanup for gdb-3.94 release final:
1832 * Makefile.dist: Remove remote-vx.c, remote-nindy.c, and all
1833 the .c files from vx-share and nindy-share, from the various
1834 macros, since they are not found via ALLDEPFILES.
1835 (SFILES): Add tm-i960.h.
1836 (alldeps.mak rule): Break out ALLDEPFILES_MAINDIR and
1837 ALLDEPFILES_SUBDIR. List all the nindy and vxworks subdir files
1839 (TAGFILES_MAINDIR): Change ALLDEPFILES to ALLDEPFILES_MAINDIR.
1840 (gdb.tar.Z): Use ALLDEPFILES_SUBDIR as well as SFILES_SUBDIR.
1842 Mon Feb 25 16:02:35 1991 Cygnus John Gilmore (cygnus at oldman)
1844 * am29k-tdep.c: Add contribution line.
1845 (examine_prologue): Cache information about function prologues in
1846 the misc-function-vector to avoid lots of references over the
1847 serial line while examining instructions.
1849 * core.c (core_close): New function made from cleanup_core.
1851 * core.c, exec.c, inftarg.c, remote-eb.c, remote-nindy.c,
1852 remote-vx.c, remote.c, target.c, target.h,
1853 Update target_ops vector to add attach, close, and load entries.
1854 Use add_syms_addr_command, not add_file_addr_command, for
1855 add_file. Break out close routine from existing code.
1857 * dbxread.c (really_free_pendings): Don't free pending_blocks;
1858 they are in an obstack.
1859 (read_dbx_symtab): Relocate end_of_text_addr in the psymtab.
1861 (define_symbol): Add symbol type parameter; change callers;
1862 pass type parameter to DBX_PARM_SYMBOL_CLASS macro to allow
1863 it to influence the symbol class on the i960.
1864 (define_symbol): Swap LOC_CONST's into target byte order.
1866 * exec.c (exec_close): New function.
1867 (exec_file_command): Call it.
1869 * findvar.c (read_relative_register_raw_bytes): Doc byte order,
1870 Fix byte order of frame pointer.
1871 (read_var_value): Result of 0 if var's value can't be found,
1872 e.g. missing FRAME_ARGS_ADDRESS. Byte-swap LOC_CONST and
1873 LOC_LABEL values to target order. Add LOC_LOCAL_ARG.
1874 (locate_var_value): Use read_var_value and use its lazy address
1875 as the location of the var's value. Lint.
1877 * i960-pinsn.c (next_insn): Add routine from vxgdb for scanning
1880 * i960-tdep.c (arg_address, i960_frame_find_saved_regs): Remove
1881 obsolete Intel versions in favor of vxgdb versions.
1882 (check_host, byteswap, byteswap_val, reorder_val): Eliminate
1883 code dealing with byte order of values, which Intel did in host byte
1884 order rather than gdb-4's target byte order.
1885 (i960_frame_chain_valid): Move to nindy-tdep.c.
1886 (examine_prologue, skip_prologue, frame_find_saved_regs,
1887 frame_args_address, leafproc_return, saved_pc_after_call,
1888 pop_frame): Add vxgdb versions from Mark Fox.
1889 (examine_prologue, frame_struct_result_address): Add code
1890 to deal with the saved value of G13 (struct return address
1892 (frame_args_address): Modify Mark's version to prefer the
1893 saved value over the current value in the topmost frame.
1894 Cache result in the frame info to avoid performance hair in
1896 (print_fault): Add gdb960 code for printing faults.
1897 (_initialize_i960): Actually call check_host.
1899 * ieee-float.c (ieee_extended_to_double, ieee_double_to_extended):
1900 add stub routines. FIXME, these currently just return zero!
1902 * infcmd.c (program_info): Use PRINT_RANDOM_SIGNAL.
1903 (attach_command): Call target_attach, not target_open, now.
1905 * infrun.c (normal_stop): Make global, not static, for vx_attach.
1906 (child_attach): Rename from child_open.
1907 (wait_for_inferior): Use PRINT_RANDOM_SIGNAL. If stop_pc is zero,
1908 don't confuse it with a zero step_resume_break_address.
1910 * inftarg.c (child_detach): Eliminate inferior_pid test.
1911 (child_files_info): Clean up message a bit.
1912 (child_ops): Use child_attach, not child_open, to attach.
1914 * mem-break.c: #ifdef out the whole file if BREAKPOINT is not
1915 set (e.g. on VxWorks or NINDY). Move read_memory_nobpt from
1916 findvar.c to here, since it depends on the contents of the
1917 shadow_contents of breakpoints, but keep if #if 0 since it is
1920 * nindy-tdep.c: New file, contains nindy_frame_chain_valid, moved
1923 * printcmd.c (address_info): Handle LOC_LOCAL_ARG. Lint.
1924 (ptype_command, display_command): Eliminate have_inferior_p and
1925 have_core_file_p in favor of target_has_stack or
1926 target_has_execution.
1927 (print_frame_args): Handle LOC_LOCAL_ARG. Eliminate duplicate
1928 code for actually finding the values of arguments, though we still
1929 keep track of the maximum stack offset for use in printing unnamed
1930 arguments. Handle missing FRAME_ARGS_ADDRESS.
1932 * remote-nindy.c (i960_print_fault): Move to i960-tdep.c.
1933 (struct nindy_regs): Define registers passed to/from nindy.
1934 (nindy_fetch_registers, nindy_store-registers): Translate between
1935 nindy and GDB formats for the registers.
1936 (dcache_init): Statically allocate the cache, since it was being
1937 allocated by a malloc that was never freed anyway.
1938 (nindy_create_inferior): Error, not core dump, if no exec file.
1939 (nindy_before_main_loop): Use target_load, not target_add_file.
1941 * remote-vx.c (net_load): Specify large timeout for load
1942 requests. Allow user to break out with INTERRUPT.
1943 (net_break): Remove useless code, clean up. Change callers.
1944 (parse-args, skip_white_space, find_white_space): Clean up arg
1945 parsing to cope with quoted strings.
1946 (net_wait, net_quit): Never call error, just return status.
1947 (vx_read_register, vx_write_register): Cleanup status checking.
1948 #ifdef the code based on which CPU we are using (960 or 68k),
1949 FIXME, this should be completely general but it isn't yet.
1950 (vx_xfer_memory, vx_resume): Cleanup status checking.
1951 (vx_run_files_info): Improve message.
1952 (vx_load_command): Renamed from vx_add_file_command. Allow load
1954 (net_ptrace): Remove unused routine.
1955 (vx_wait): Adopt code from vxgdb960 to cope with broken
1956 connections to target machine and prompt to disconnect. Remove
1957 debug printouts. Map some EVENT_'s to SIGnals.
1958 (add_symbol_stub, vx_open): Print names of object files we found,
1959 and "ok" if we read their symbols OK. Clarify output in general.
1960 (vx_attach, vx_detach, vx_kill): Add these commands.
1961 (vx_convert_from_virtual, vx_convert_to_virtual): Simplify.
1962 (vx_run_ops): Turn off all_mem, to avoid spurious msg in the
1963 "info files" output, and create_inferior, since we already have
1966 * stack.c (frame_info): Replace Frame_unknown with 0.
1967 (print_frame_arg_vars): Handle LOC_LOCAL_ARG.
1968 (return_command): Pop until the PC matches as well as the FP,
1969 so it works even if the FP is shared with another function,
1970 as in "frameless" or "leaf" procedures.
1972 * symfile.c (load_command): renamed from add_file_target_command.
1973 (add_syms_addr_command): renamed from add_file_addr_command.
1974 (add_syms_command): Stub to call target_add_syms.
1975 (_initialize_symfile): Change command names and descriptions,
1976 add-file => add-syms, and load from alias to its own command.
1978 * target.c (kill_or_be_killed, maybe_kill_then_attach,
1979 maybe_kill_then_create_inferior): Default for attempts to start
1980 a process, if one is already running, is to ask about killing
1981 it and retry if yes.
1982 (upstack_create_inferior): #if-0 it, strata obsolete it.
1983 (push_target, unpush_target, pop_target): to_close() a target
1984 before unstacking it.
1985 (target_info): Renamed from target_files_info.
1986 (_initialize_targets): Rename "i files" as "i target", accessible
1989 * target.h: Improve comments about the target_ vectored routines.
1991 * tm-i960.h: Remove NINDY-specific stuff to tm-nindy960.h.
1992 Convert commenting style to standard GNU style.
1993 (DBX_PARM_SYMBOL_CLASS): allow LOC_LOCAL_ARG's to be recognized.
1994 (SKIP_PROLOGUE): No longer a no-op.
1995 (SAVED_PC_AFTER_CALL): Now handles leaf procedures.
1996 (*_REGNUM): Sort register numbers.
1997 (REGISTER_BYTES, REGISTER_BYTE, REGISTER_RAW_SIZE,
1998 MAX_REGISTER_RAW_SIZE, REGISTER_CONVERTIBLE,
1999 REGISTER_CONVERT_TO_VIRTUAL, REGISTER_CONVERT_TO_RAW): Float regs
2000 are now 10 byte extendeds, not 8 byte doubles.
2001 (FRAME_CHAIN_VALID): Make this config-dependent, since it differs
2002 for nindy versus vxworks targets. FIXME, this should possibly go
2003 in the target vector.
2004 (EXTRA_FRAME_INFO, INIT_EXTRA_FRAME_INFO): Cache both
2005 frame_saved_regs and arg pointer with each frame.
2006 (FRAMELESS_FUNCTION_INVOCATION): New leafproc support.
2007 (FRAME_ARGS_ADDRESS): Use cached result.
2008 (FRAME_ARGS_ADDRESS_CORRECT): New, avoids g14 guessing.
2009 (FRAME_FIND_SAVED_REGS): Change arg to subsidiary fn.
2010 (PRINT_RAMDON_SIGNAL): Call print_fault.
2011 (POP_FRAME): Now works.
2013 * tm-nindy960.h: Break this off tm-i960.h. NINDY-specific
2014 option parsing and startup; STACK_END_ADDR, FRAME_CHAIN_VALID,
2015 BREAKPOINT, and DECR_PC_AFTER_BREAK are here.
2016 (ADDITIONAL_OPTION_HANDLER): use target_load, not
2019 * tm-vxworks960.h: Break this off tm-i960.h. VxGDB specific
2020 startup; DECR_PC_AFTER_BREAK, and FRAME_CHAIN_VALID are here.
2022 * valarith.c (value_subscripted_rvalue): Avoid handling
2023 floats and doubles specially; it gave alignment errors. Lint.
2025 * valops.c (value_of_variable, value_of_this): Error if unknown
2028 * valprint.c (print_floating): Bcopy rather than pointer-deref,
2029 to avoid alignment problems.
2030 (value_print): Handle unknown value address.
2031 (cplus_val_print): Two args are ignored; remove them. Change caller.
2032 (val_print): Use unpack_long rather than pointer-deref.
2035 (unpack_long, unpack_double): Use bcopy rather than pointer-deref
2036 to avoid alignment problems.
2037 (value_being_returned): Error if return value unknown.
2038 (set_return_value): Add bogosity warning, FIXME. *
2040 * TODO: A woman's work is never done.
2042 * Makefile.dist: Distribute REMOTE_OBS into tconfig files.
2043 Separate INCLUDE_CFLAGS for use with lint. Add LINTFILES.
2044 Add ieee-float.o to OBS.
2045 * tconfig/{nindy960,vxworks68,vxworks960}: Include the desired
2046 REMOTE_OBS remote-interface files in the TDEPFILES and TM_FILE.
2047 * tconfig/i960: FIXME. Half-merge, produce warning if config'd.
2049 Changes to generalize the VxWorks RPC protocol slightly, to handle
2050 i960 as well as 68000.
2052 * vx-share/dbgRpcLib.h (VX_SOURCE_STEP): Add.
2053 * vx-share/reg.h: Produce i960 regs #ifdef I80960
2054 * vx-share/xdr_ptrace.c: Skip FPA registers if 960.
2055 * vx-share/xdr_rdb.h: Add SOURCE_STEP struct and xdr decl.
2056 * vx-share/xdr_rdb.c: Add xdr_SOURCE_STEP routine.
2057 * vx-share/xdr_regs.c: Add xdr_regs, xdr_fp_status, xdr_ext_fp
2058 for i960. Change xdr_vectors to xdr_opaques for 68k registers,
2059 so they will move in target byte order rather than network
2060 byte order (happens to be the same).
2062 Mon Feb 25 03:41:44 1991 John Gilmore (gnu at cygint.cygnus.com)
2064 * tm-convex.h (END_OF_TEXT_DEFAULT): Remove #if 0'd block.
2066 Sun Feb 24 00:55:53 1991 John Gilmore (gnu at cygint.cygnus.com)
2069 Add contribution lines to various files, showing where they
2072 * breakpoint.c (break_insn, check_break_insn_size,
2073 read_memory_nobpt): Remove to mem-break.c.
2075 * xm-*.h, param-no-tm.h, tm-29k.h, valprint.c: Change BYTE_ORDER to
2078 * tm-29k.h (STAB_REG_TO_REGNUM): Warn user if symbol table
2079 entry has bad register number. This change is not
2080 tested in this release, FIXME.
2082 * frame.h: Eliminate Frame_unknown in favor of a simple zero.
2085 * value.h: Force value's contents field to be aligned to hold
2086 at least a double or a long long (if supported). This avoids
2087 doing bcopy's in and out of the contents field.
2089 (step_1): Avoid coredump under obscure circumstances when we
2092 * symtab.h (misc_info): Add field to misc function vector for
2093 any kind of cached information the target code desires. AMD
2094 29000 uses this to avoid repeating examine_function_prologue's.
2096 * coffread.c: Lint. Remove static symfile, read_section_header.
2097 core.c (have_core_file_p): Lint: remove.
2098 expprint.c (print_subexp): Lint.
2099 infptrace.c, valops.c, valprint.c: lint.
2101 Roll in changes from vxgdb-5.0.1:
2103 * symtab.h: Comment byte order of each address class. Add
2104 LOC_LOCAL_ARG for frame-relative args (960).
2105 expread.y: Use LOC_LOCAL_ARG where LOC_ARG is used.
2106 symtab.c, symmisc.c: ditto.
2108 * infrun.c (init_wait_for_inferior): Clear stop_signal.
2110 * remote.c (remote_resume): Error if resume with a signal.
2112 * symfile.c (prim_record_misc_function): Clear misc_info.
2113 (fill_in_vptr_fieldno): Check stub type of arg.
2115 * valops.c (value_cast): Avoid looking up names of types whose
2116 name we don't know, to prevent coredump. Sun CC produces typedef
2117 rtx and the name of *rtx is zero...
2119 Mon Feb 18 21:16:25 1991 John Gilmore (gnu at cygint.cygnus.com)
2121 Roll in changes from final AMD 29000 port (Tiemann).
2123 tconfig/am29k: Add COFF_ENCAPSULATE and TARGET=TARGET_AM29K
2124 for ../include/a.out.encap.h. This might not work now that BFD
2125 is separately compiled. Instead, BFD support for encap will have
2126 to translate machine type 29k into the right COFF_MAGIC.
2128 * infcmd.c: Remove references to inferior_pid that aren't used
2129 in actual ptrace calls; use target_has_execution, etc.
2130 (have_inferior_p): Remove function.
2131 (program_info): Print target info rather than "process number";
2132 avoid gratuitous messages unless from_tty.
2133 (run_stack_dummy, finish_command): Set proceed_to_finish.
2134 infrun.c: Remove inferior_pid refs. Decl & init proceed_to_finish.
2135 main.c: Lint. Lose have_inferior_p().
2136 inferior.h (have_inferior_p): Remove, lint.
2137 (proceed_to_finish): Add flag to ask that all regs be saved
2138 by normal_stop, for the few commands that need it, speeding up
2139 serial I/O. Add comments to stop_registers.
2141 * remote-eb.c: Remove newline from breakpoint message we grep
2142 for. Never time out when running the user program.
2146 Wed Feb 13 15:34:40 1991 John Gilmore (gnu at cygint.cygnus.com)
2148 Roll in changes from vxgdb-5.0.1:
2150 * dbxread.c (read_dbx_symtab): If we encounter a "FORTRAN COMMON"
2151 symbol in its raw form, we are processing an unlinked ".o" file.
2152 See if the target environment has assigned it an address, using
2153 target_lookup_symbol (VxWorks does), and enter it into the symtab
2156 * tm-vxworks.h (FRAME_CHAIN, FRAME_CHAIN_VALID): Override usual
2157 68k versions for a simpler version that assumes zero FP at bottom.
2158 Fixes bug of truncated stack reports.
2160 * target.h (target_lookup_symbol): Define this routine's args
2161 and result, finally.
2163 * target.c (nosymbol): Default routine for target_lookup_symbol.
2164 (target_default): Default lookup_symbol and call_function too.
2165 (files_info): Only print has_all_memory warning if a non-dummy
2168 * remote-vx.c (vx_read_register, vx_convert_to_virtual,
2169 vx_convert_from_virtual): If target does not have floating point,
2170 zero register "values", and avoid doing cross-net conversions.
2171 (vx_lookup_symbol): Rename net_lookup_symbol, add to vectors.
2172 (vx_open): Rearrange code that attaches to target and reads
2173 symbols for all loaded modules, to work if some of the modules
2174 are not accessible. Add symbol_stub() and add_symbol_stub()
2175 as callbacks from catch_errors(). Allow connect attempt to be
2176 interrupted painlessly with ^C (FIXME, there are still some bugs
2177 if the interrupt happens during symbol reading.). Print
2178 final message with puts_filtered, since symbol messages are
2183 * main.c (catch_errors): Only print errstring if non-null.
2184 (command_loop): Avoid an ioctl per command to test ISATTY.
2186 * remote-vx.c (net_load): make static; avoid sophomoric msg.
2187 (vx_xfer_memory): Return correct result!
2188 (vx_files_info): Indicate whether target has float or not.
2189 (vx_lookup_symbol): Complain, not error, if target gone.
2190 (vx_open): Print "Connected" msg before disabling immediate-quit.
2191 [FIXME: lookup_symbol and vx_open changes need testing.]
2193 target.c, remote-eb.c, inftarg.c, am29k-opcode.h, target.h,
2194 tm-29k.h, tmm-vxworks68.h, symfile.c, gdb-int.texinfo: Add
2195 contributor lines and update copyrights to 1991.
2197 Changes from an attempted H-PUX host port:
2199 * infptrace.c (PT_ATTACH, PT_DETACH): Handle HP/UX, which
2200 defines PT_ATTACH and PT_DETACH but not PT_KILL.
2201 * remote-eb.c (eb_open): Misplaced endif kills sysv H/PUX.
2202 * remote-vx.c: include <sys/time.h> for HPUX.
2203 * hp300hpux-xdep.c (fetch_core_registers): Rewrite old
2204 "core_file_command" routine to BFD regime. May not work yet.
2206 Attempted port of "gdb-3.4 Van Jacobson xgdb" to modern gdb.
2208 * xgdb.c: Replace X10 version with some VJ version.
2209 (FIXME: Its copyright assignment is not on record.)
2210 * xgdb.c: Update include files to X11R4 (Xaw crud).
2211 (xgdb_display_source, create_text_widget): fix call to
2212 get_filename_and_charpos. Rewack source window stuff for X11R4
2213 (gleaned from include files, and "nm's" of binary libraries, since
2214 I had no doc available).
2215 (append_selection, append_selection_word): Disable with FIXME
2216 since R4 changed interface here.
2217 (create_buttons): Add back the old set of buttons.
2218 (xgdb_create_window): Fix call to XtInitialize (&argc not argc).
2220 * Makefile.dist (xgdb, xgdb-init.c): Update for X11R4 on Suns.
2221 Roll VERSION to 3.94 (not yet final though).
2223 Sat Feb 9 09:46:25 1991 John Gilmore (gnu at cygint.cygnus.com)
2225 * obstack.h (obstack_ptr_grow, obstack_ptr_grow_fast,
2226 obstack_int_grow, obstack_int_grow_fast): Eliminate
2227 cast on left of assignment, which gives MIPS cc fits and is
2230 * sparc-pinsn.c (print_insn): Eliminate 'set' test, subsumed by
2231 F_ALIAS. Use printf, not fprintf, when not passing a file
2233 (compare_opcodes): Check that identical instructions have
2234 identical opcodes, complain otherwise.
2236 * sparc-opcode.h (st %fsr): Fix opcode "lose" mask. This
2237 was reported by Roland McGrath.
2238 (unimp): Only match if exactly zero instruction. (Roland)
2239 (branches and traps): Generate all variations of these
2240 instructions with macros, based on a single call that defines
2241 each condition name and its binary representation.
2242 (set): Turn on alias bit, to avoid test in sparc-pinsn.c.
2244 * valprint.c (val_print_fields): Take, and use, format parameter.
2245 This means that "p/x struct" again prints the elements in the
2246 desired format. Changed callers.
2248 * stack.c (frame_info): Use filtered output, and indicate wrap
2249 points. Remove kludgy formatting designed to avoid line wrap.
2251 * utils.c (wrap_here): If the line is already full (because
2252 we had printed a long indent or long wrapped string), do an
2253 immediate newline-and-indent.
2255 * m68k-pinsn.c (print_insn_arg): Bugfix from
2256 ntmtv!thompson@ames.arc.nasa.gov (Mike Thompson): 'bkpt #0'
2257 instruction is incorrectly disassembled as bkpt #8.
2259 * dbxread.c (end_psymtab): Bugfix from Peter Schauer
2260 <pesrem@regent.e-technik.tu-muenchen.de>: If you want to set a
2261 breakpoint in a *.y file gdb will say Reading in symbols for *.y...
2262 and then will dump core (sometimes). I traced it back to an
2263 uninitialized symfile_name in psymtab_to_symtab.
2264 (const_vol_complaint): Add quotes to message.
2265 (define_symbol): Only believe line number if gcc_compiled.
2266 Avoid allocating symbol if we will not return it.
2268 Add target strata support so that newly established targets go
2269 into their right place in the target stack (e.g. a new exec file
2270 doesn't wipe out the ability to access the running process).
2272 * target.h, core.c, exec.c, inftarg.c, remote-eb.c,
2273 remote-nindy.c, remote-vx.c, remote.c, target.c: Add to_stratum
2274 and initialize it properly in all the targets.
2276 * target.h: Document strata. Change return type of push_target.
2278 * target.c (nomemory): new function for dummy memory access.
2279 (tcomplain): Rename complain, now also used in symfile.c.
2280 (push_target): Push targets within strata. New return value shows
2281 whether new target is on top of stack or not. Always keep dummy
2283 (target_files_info): Ignore dummy target.
2285 * core.c (core_open): Warn user, and skip accessing file, if the
2286 core target is not the topmost target in the stack.
2287 * remote-nindy.c (nindy_create_inferior): Avoid unpush_target, now
2290 * remote-vx.c: Remove vx_prepare_to_store from vxworks memory
2291 target_ops, it doesn't belong there since we have no regs there.
2292 Change name of target from machine => memory to clarify.
2294 Thu Feb 7 16:32:09 1991 John Gilmore (gnu at spiff.cygnus.com)
2296 * Freeze version 3.93 for release.
2298 * Makefile.dist: Handle vx-share and nindy-share subdirs
2299 properly when building gdb.tar.Z.
2301 * symtab.c: lint; add no_symtab_msg to consolidate the messages
2302 printed in various places, so I could change just one copy.
2304 * dbxread.c, coffread.c: Change references to bfd->iostream
2305 to cast to FILE *, now that BFD avoids needing types defined
2306 in other header files.
2308 Tue Feb 5 21:39:35 1991 John Gilmore (gnu at cygint.cygnus.com)
2310 * command.c, dbxread.c, expprint.c, infcmd.c, infptrace.c,
2311 infrun.c, printcmd.c, remote-nindy.c, source.c, sparc-tdep.c,
2312 sparc-xdep.c, symfile.h, symmisc.c, utils.c, valprint.c: Lint
2313 (actually gcc -Wall).
2315 * dbxread.c: Remove first_global_sym, last_global_sym, since
2316 they are never referenced.
2318 * defs.h (baud_rate): Declare.
2319 main.c: Define it, and add the -b option to set it.
2321 * gdb-int.texinfo: Add text on how to define a new host or target
2322 architecture, prompted by Per Bothner's questions about MIPS
2325 * gdb.texinfo: Document "complaints". Change doc of -q since
2326 gdb no longer prints the copyright and blurb if you specify a file
2327 name to be debugged (just like Emacs). Add doc for Nindy-specific
2328 command line flags for specifying target serial port and such.
2329 Update copyright to 1991.
2331 * gdbcore.h: Remove a large mass of now-useless crud, since BFD
2332 has taken over for us the job of ripping up executable files. The
2333 crud caused Per Bothner's port to not compile.
2335 * infrun.c (normal_stop): Avoid printing "Program exited
2336 normally" if we are in batch mode. This allows a GDB which
2337 executes a program on a target system, to behave like a Unix
2338 command (input from stdin, output to stdout, no extraneous
2341 * main.c (main): Allow additional machine-dependent command line
2342 options to be specified with the ADDITIONAL_OPTIONS,
2343 ADDITIONAL_OPTION_CASES, ADDITIONAL_OPTION_HELP, and
2344 ADDITIONAL_OPTION_HANDLER macros. Also allow machine-dependent
2345 processing to occur just before the main loop with
2346 BEFORE_MAIN_LOOP_HOOK.
2347 (main): If a "core file" argument is specified, and it is not a
2348 core file, try it as a process ID to attach.
2349 (symbol_completion_function): Attempt to cope with
2350 "show screen-" TAB, not very successfully. This needs more work,
2352 (batch_file): New function, returns whether we are reading
2353 commands from an interactive tty on stdin, or from somewhere else.
2354 Called by normal_stop since it doesn't get from_tty passed down
2355 to it like many commands do.
2357 * remote-nindy.c: Handle command line options for nindy
2359 (nindy_before_main_loop): Prompt user for tty name if they
2360 don't specify it before getting to the interactive command loop.
2362 * tm-i960.c: Add ADDITIONAL_OPTIONS, etc, to handle -O, -brk,
2363 and -r command line options. Also add hook before main loop
2364 to make it easy to specify a tty.
2366 * TODO: More things to do, one done.
2368 Mon Feb 4 23:57:39 1991 John Gilmore and Mike Tiemann (at cygint.cygnus.com)
2370 * dbxread.c: Make complaint() calls pass pointer, not struct.
2371 Add complaints about badly formatted C++ type information
2372 (const/volatile indicator, and parse errors resulting in
2373 error_type). Fix C++ virtual member fn comment.
2374 (read_struct_type): Avoid bumping pointer if we got a parse
2375 error; this prevents our walking beyond the end of a string.
2376 Terminate loop on null char as well as semicolon.
2377 (process_one_symbol): Fix the LBRAC fix so that it uses the
2378 last previous SLINE, FUN, or SO record's PC address. C++ debug
2379 symbols did not have SLINE records in a useful order compared
2380 to the LBRAC records.
2381 (define_symbol): Handle "catch" records.
2383 * symtab.c (check_stub_type): Added new complain
2384 `stub_noname_complain' and added a consistency check to
2385 keep the debugger from crashing when finishing from an
2386 exception frame. A real fix will be needed later.
2388 Sat Feb 2 10:43:05 1991 John Gilmore (gnu at cygint.cygnus.com)
2390 * infcmd.c (attach_command): Make global.
2392 * Makefile.dist (REMOTE_OBS): Make these compile by default,
2393 but make them easy to comment out. Perhaps later they should
2394 be enabled by what CPU you configure for? FIXME.
2395 (VERSION): Roll to 3.93.
2396 (pinsn.o): Remove rule for obsolete file.
2397 (dbxread.o,coffread.o,mipsread.o): Use ${srcdir} explicitly.
2399 Run down a problem that manifested by printing the wrong function
2400 name in stack traces of read_ofile_symtab. Turned out that the
2401 problem was the SunOS 4.1.1 (and previous) C compiler outputs
2402 the LBRAC symbol with an address in the *data* segment, which
2403 blew our binary search through the blocks.
2405 * dbxread.c: Use the complain() facility consistently to bitch
2406 about problems in the symbol file we are reading.
2407 (finish_block): Add code to check the nesting of the blocks;
2408 complain and Procrust them to fit if wrong.
2409 (make_blockvector): Check the order of the blocks, complain
2410 [but don't cope] if wrong.
2411 (process_one_symbol): ifndef SUN_FIXED_LBRAC_BUG, check LBRAC
2412 symbols to be sure their PC value is greater than the last SLINE
2413 (line number) symbol we've seen, complaining and adopting the
2414 SLINE PC value if wrong.
2416 * symfile.h (struct complaint, complaint_root, complain,
2417 clear_complaints): Add.
2418 * symfile.c (complain, complaint_root, clear_complaints): Add
2419 facility to deal with non-fatal complaints and to regularize their
2421 (symbol_file_add): Clear complaint counters to allow new complaints.
2422 (initialize_symfile): Add 'set complaints' and 'show complaints'.
2424 * dbxread.c (dbx_symfile_read): Remember the address and size
2425 of the string table for the main symbol file, so we won't read it
2427 (dbx_psymtab_to_symtab): Fix the check for main symbol file,
2428 to avoid reading the string table yet again. Lint.
2429 (throughout): Improve filtered output, including word wrap.
2430 (read_range_type): Improve Bothner's fix to handle other types too.
2432 * utils.c: Improve line wrap implementation. Handle unlimited
2433 width by making chars_per_line unsigned.
2434 (puts_filtered): New, easy, function.
2436 * defs.h (puts_filtered): add.
2438 * mipsread.c (compare_symbols, sort_symtab): Remove these fns,
2439 call the identical sort_symtab_syms() in symfile.c instead.
2441 * expread.y: Suggest the `file' command rather than `symbol-file'.
2443 * command.h (enum var_types): Add zinteger for seroable
2445 * command.c (do_setshow_command): Handle var_zinteger. Restructure
2446 nested if's into a switch.
2448 * breakpoint.c (bpstat_print): If bpstat "print" flag is not set,
2449 we did not stop because of a breakpoint (it must have been for
2450 some other reason, like a "stepi"), so don't print anything.
2452 * symtab.c: Include <sys/types.h> all the time. Now that BFD
2453 doesn't include <sys/types.h>, old SunOS's require it for
2456 Sat Feb 2 10:39:15 1991 Per Bothner (bothner@cs.wisc.edu)
2458 A test port of gdb-3.92.6 to the Sony NEWS.
2461 Don't normally link in remote- or vx stuff.
2462 Some of it doesn't compile, and it wastes space for 99% of the users.
2463 Remove reference to no-longer-used HAVE_VPRINTF.
2464 Fixed BFD_DEP typo to BFD_DIR.
2466 Fix cast in arg to bfd_h_getlong.
2467 Make char *prefix be const.
2468 Fix how certain range types are mapped into builtin unsigned int types.
2470 Remove 2 #includes. They cause errors (on Sony, at least),
2471 and aren't needed (they wern't in earlier versions).
2473 print_address_symbolic should never demangle labels
2474 (since it prints *assembler-level* labels).
2476 [This was superseded by the change to printcmd below.]
2479 Add some "volatile" return types to avoid warnings.
2480 If MISSING_VPRINTF add vprintf function and not just macro
2481 (since vprintf is used in printcmd.c).
2483 Unless __GNUC__, use obstack_grow instead of obstack_ptr_grow.
2484 (The latter isn't grokked by some PCC-based compilers.)
2486 [This change is in abeyance, we prefer to fix obstack_ptr_grow.]
2488 Make chunk size of dont_print_obstack 32*4 instead of default 4096.
2489 * nindy-share/coffstrip.c
2490 Added some forward declarations (otherwise, gcc complains
2491 about implicit extern redefined as static).
2493 Sun Jan 20 02:38:19 1991 John Gilmore (gnu at cygint.cygnus.com)
2495 Changes inspired by Per Bothner:
2496 * printcmd.c (print_address_symbolic): Take additional parameter
2497 specifying whether to demangle.
2498 (print_address): Pass in asm_demangle to control demangling.
2499 (print_address_demangle): New fn, takes explicit arg to control
2501 * utils.c: Add new vars demangle and asm_demangle, and let them
2503 (fputs_demangled): If !demangle, just print the argument.
2504 (fprint_symbol): If !demangle, just print raw symbol.
2505 * valprint.c (val_print): Call print_address_demangle rather than
2506 print_address, to cause demangling to depend on the global
2507 rather than assembler-level demangling setting.
2508 * WHATS.NEW, gdb.texinfo: Document.
2510 * main.c (show_command): Show all settings if no arg.
2511 (initialize_main): Make "info set" the same as naked "show".
2512 * command.c (cmd_show_list): Handle prefix commands in the
2513 list, and print the name of the setting as well as its English
2514 description and value.
2516 Allow gdb functions to specify where a line should wrap if it
2517 exceeds the size of a terminal line. Use it to make the output
2519 * utils.c (set_screen_width_command): New fn, mallocs a buffer
2520 of the right size when screen width changes.
2521 (set_screensize_command, screensize_info): Remove #if 0'd fns.
2522 (wrap_here): New fn, indicates a point in the output where we
2523 should wrap the line rather than just letting it overflow at a
2525 (fputs_filtered): Implement wrapping.
2526 (n_spaces): New fn, returns a pointer to N spaces.
2527 (print_spaces_filtered): Use n_spaces.
2528 * defs.h (n_spaces): Declare.
2529 * stack.c (print_frame_info): Wrap with 4-space indent after
2530 fn name and before filename and line number.
2531 * printcmd.c (print_frame_args): Wrap with 4-space indent
2532 before each argument name is printed.
2533 * valprint.c (value_print): Wrap with no indentation before
2535 (val_print_fields): Wrap with indentation relative to nesting
2536 level before each field name.
2537 (val_print): Wrap with nesting indentation before array elements.
2538 * command.c (do_setshow_command): Avoid extra newlines,
2539 wrap with 4-space indent around values printed, end with period.
2540 * WHATS.NEW, gdb.texinfo, gdb-int.texinfo: Document.
2542 * breakpoint.c (breakpoint_1): Implement addressprint for
2543 "info breakpoints" display. Change file name and line number
2544 format to " at file:nnn" rather than " (file line nnn)".
2545 * gdb.texinfo: Document.
2548 Fri Jan 18 07:21:25 1991 John Gilmore (gnu at cygint.cygnus.com)
2550 Frozen for gdb-3.92.6 release.
2552 README, WHATS.NEW: Update for 3.92.6 release.
2554 tconfig/{altos, i386v, i386v32, m88k, umax}: Eliminate
2555 coffread.o from configs since it is now built by default.
2556 tconfig/{3b1, altosgas, arm, convex, hp300bsd, hp300hpux,
2557 i386v-g, i386v32-g, isi, merlin, news, news1000, np1, pn,
2558 pyramid, symmetry, vax, vxworks68}: Eliminate dbxread.o
2559 from configs since it is now built by default.
2561 Makefile.dist: Update for release 3.92.6. Handle files that
2562 have been moved to ../include, ../getopt, or ../bfd. Add
2563 saber.suppress and tests directory. Add config.status to
2564 the release (it will say "none").
2566 coredep.c: Minor formatting fixes.
2568 These changes were made in early December but only checked in now:
2569 * nindy-share/Onindy.c, nindy-share/coffstrip.c,
2570 nindy-share/nindy.c: lint
2571 * nindy-share/nindy.c (ninStopWhy): Don't byteswap the
2572 register values coming back from the target; we store values
2573 in target byte order everywhere.
2575 Wed Jan 16 19:01:37 1991 John Gilmore (gnu at cygint.cygnus.com)
2577 * am29k-opcode.h, am29k-pinsn.c: Add 29050 opcodes.
2579 * valprint.c (cplus_val_print, val_print_fields): New functions,
2580 which print C++ objects. They conspire to avoid printing a
2581 virtual base class more than once, following all the twists and
2582 turns of C++ virtual base rules.
2583 (val_print): Call the above rather than do it by hand.
2585 * symfile.c (symbol_file_add): Only reset symfile_mtime for main
2586 symbol file, not for added files like shared libs. This really
2587 needs to be generalized to a timestamp per file.
2589 * core.c (cleanup_core): Avoid coredump if no core file.
2591 * config.gdb: Accept -host or -target in place of +host or
2594 * coffread.c (find_linenos): Avoid desupported BFD interface
2595 to line numbers. We still read them manually rather than using
2596 BFD's "generic" features.
2598 * gdbrc.tex, threecol.tex: Add GDB reference card and its
2600 Makefile.dist: Add refcard to OTHERS list for creating tar files.
2602 * Makefile.dist: Eliminate use of $< in explicit targets.
2604 * readline/Makefile: Use $< rather than $*.c, which does not
2605 include the VPATH in GNU Make.
2607 * tconfig/i960-bout, tconfig/i960-coff: These are identical
2608 copies of tconfig/i960, added for global configuration
2609 compatability. All i960 versions can read both coff and b.out.
2611 * tm-88k.h: Fix multiline macro that lacked \'s. Remove
2612 COFF_FORMAT and COFF_CHECK_X_ZEROES since these are now handled
2615 * TODO: Think of more things to do.
2617 Wed Jan 2 19:09:29 1991 John Gilmore (gnu at spiff.cygnus.com)
2619 tconfig/{am29k,i960,sun2*,sun3*,sun4*}: Eliminate config
2620 of sdb versus dbx debug symbols. Add kludge for 68881 80-bit to
2621 64-bit float conversion.
2623 tconfig/sun4, tconfig/sun3, xconfig/sun4, xconfig/sun3: Make
2624 equivalent to sun?os4 so global config works.
2626 Wed Jan 2 18:20:51 1991 John Gilmore (gnu at spiff.cygnus.com)
2628 Fix from Eberhard Mattes <mattes@azu.informatik.uni-stuttgart.de>
2630 * main.c: Only declare linesize once; declare pagesize not at
2631 all, since it is never used.
2632 (main): Clear newly allocated line before it is used.
2634 Fri Dec 28 00:13:42 1990 John Gilmore (gnu at cygint)
2636 Further stabilization for the Intel 960.
2638 * Makefile.dist: Parameterize the location of the "include"
2639 and "bfd" directories, as well as "getopt". Add symfile.c.
2640 Link in both dbxread and coffread. Fix up "make depend" to
2641 rewack the locations of include, bfd, and getopt in its output.
2643 * README: Document moving include files, improve some of
2646 * coffread.c: Move common code out to symfile.c. Change
2647 symbol_file_command style interface to use new *_symfile_init
2648 and *_symfile_read interface under BFD. Use BFD internal
2649 info to locate line table, symbols, etc.
2651 * core.c (core_fetch_registers): Rename to get_core_registers
2652 to avoid confusion with fetch_core_registers.
2653 (register_addr): Move to coredep.c, which is already machine
2654 dependent. This leaves core.c pretty clean of dependencies.
2656 * coredep.c (register_addr): Accept this routine from core.c.
2658 * dbxread.c: Move common code (with coffread.c, etc) into new
2659 symfile.c. Each psymtab now contains a pointer to the
2660 format-dependent function that knows how to read it in. Make
2662 (dbx_psymtab_to_symtab): Renamed from psymtab_to_symtab_2.
2663 (process_one_symbol): Add code to complain about a "compiler bug
2664 we muzzle here", if we actually see it.
2666 * eval.c (evaluate_subexp): Insert missing "break" statements
2667 in code that determines whether a variable is an lvalue in
2668 memory, register, or whatever. I detected this via a compiler
2669 bug in which it *almost* mashed out the whole switch statement.
2671 * gdb-int.texinfo: Add minor sections on configuring gdb for
2672 release, and about the README file.
2674 * infcmd.c (registers_info): Fix formatting somewhat. Still
2675 not as pretty as before, but it handles byte swapping.
2677 * remote-nindy.c: If data cache routines are interrupted while
2678 waiting for the remote end, be sure that any uninitialized cache
2679 blocks are on the free list, not on the valid list!
2681 * symfile.h: Flesh out this header file with all the various
2682 routines and variables that have been merged in from dbxread.c
2683 coffread.c, and symtab.c to symfile.c.
2685 * symfile.c: New file, containing code common to dbxread.c,
2686 coffread.c, and some code from symtab.c. All generic code for
2687 reading symbol files should be in here now.
2688 (unrecord_misc_function): Remove unused function.
2690 * symtab.h: Remove file-reading things to symfile.h.
2692 * symtab.c: Remove file-reading things to symfile.c.
2694 * tm-i960.h: Fix FRAME_CHAIN types; define PRINT_RANDOM_SIGNAL
2695 to decode i960 fault types.
2697 * target.h, remote.c, remote-eb.c, remote-vx.c, remote-nindy.c,
2698 target.c: Change type of the "resume" function from int to void,
2699 since its result was never used.
2701 Sat Dec 22 02:51:40 1990 John Gilmore (gnu at cygint)
2703 * main.c: Replace "stupid" with "caution"; you now "set caution
2706 * printcmd.c (print_scalar_formatted): Fix typo in 'g' format
2708 * infcmd.c (do_registers_info): Call val_print to deal with the
2709 byte order of the registers being printed. FIXME, this makes
2710 the formatting of the output uglier.
2712 * infcmd.c (wait_for_inferior): If PRINT_RANDOM_SIGNAL is
2713 defined, call it for signals the debugger doesn't itself use.
2714 The i960 uses this for more detailed fault information.
2716 * remote.c (remote_open): If arg is null, print help rather than
2719 * sparc-xdep.c (register_valid): Avoid declaring size, since
2720 various modules will think of various sizes depending on the
2721 architecture of their tm-file. FIXME, we need protection against
2722 actually entering one of those modules, which would clobber
2723 storage if not for the target architecture compiled into gdb.
2725 * stack.c (up_command, down_command): Always print the frame
2727 (up_silently_command, down_silently_command): New commands
2730 * i960-pinsn.c (reg), i960-tdep.c: Lint.
2732 * i960-tdep.c (i960_frame_chain_valid): Lookup_symbol now takes
2733 more parameters than it used to.
2735 * findvar.c (registers): Increase slop to 256 bytes, which should
2736 protect us against even most RISC machines with large register
2738 (locate_var_value): Move declaration inside related ifdef.
2740 * remote-nindy.c (): Use TIOCSETN rather than TIOCSETP
2741 throughout, to avoid throwing away buffered input from the board.
2742 (nindy_wait): Supply_register takes addr_of_value, not value.
2743 (i960_print_fault): Renamed from i80960_fault.
2744 (nindy_fetch_registers): Avoid have_regs stuff, just get them.
2745 (nindy_store_registers): Avoid regs_changed stuff, just stuff
2747 (nindy_create_inferior): Don't bother to write PC_REGNUM since
2748 we can set the PC in the call to proceed(). Unpush nindy_ops
2749 before pushing it on top, to avoid message to user. Eliminate
2750 commentary from Unix machines that just misleads here.
2751 (reset_command): Fix error message to suggest target command.
2753 Wed Dec 19 11:03:56 1990 John Gilmore (gnu at cygint)
2755 Release 3.92.5 as frozen.
2757 Stabilize the merged release...with help from lint, Saber C,
2760 Everywhere: Add include files needed to declare return types
2761 of functions called.
2763 * gdb.texinfo: Roland Pesch is documenting gdb, glory be!
2765 * breakpoint.h: Add undeclared breakpoint functions, and some
2766 functions for display handling since I couldn't think of a better
2769 * breakpoint.c (insert_breakpoints): Make code for disabling
2770 shared library bkpts more likely to work. It's used when we
2771 rerun a program and stop before the shared library has been
2773 (breakpoint_cond_eval, bpstat_stop_status): Pass arg as int,
2774 cast from pointer, so it squeezes through catch_errors.
2775 (bpstat_stop_status): Fix logic broken some time ago. We now
2776 always create a bpstat if the stop address matches a breakpoint,
2777 even if we don't stop there -- just like the old code used to do
2778 before I got my fingers into it (sigh).
2779 (breakpoint_1): Print "ignore count" after "stop only if"
2780 condition, since that's how it actually works.
2781 (mention): Handle watchpoints as well as breakpoints.
2782 (watch_command): use set_raw_breakpoint and mention to do most
2783 of the work (and initialize all the fields!). Only pass one
2784 arg to parse_c_expression, since that's all it takes.
2786 * command.c (not_just_help_class_command): Rename arg to args
2787 since we ignore "unused argument" warnings on vars named "args".
2788 inflow.c (child_terminal_info): ditto.
2789 infptrace.c (kill_inferior): ditto
2790 main.c (catch_errors, version_info, quit_command, pwd_command,
2791 source_command, dump_me_command, editing_info,
2792 set_history_size_command, set_history, show_history,
2794 stack.c (locals_info): ditto
2795 target.c (target_files_info): ditto
2796 valprint.c (set_input_radix, set_output_radix): ditto
2798 * core.c: Remove old variables for handling core and exec file
2799 sections (data_start, data_end, stack_start, stack_end,
2800 reg_stack_start, reg_stack_end, reg_stack_offset, text_start,
2801 text_end, exec_data_start, exec_data_end, text_offset,
2802 exec_data_offset, data_offset, stack_offset). They're
2803 superseded the more general build_section_table and
2805 (get_exec_file): Mention the `file' command.
2806 (read_memory_check): Rename to memory_error, and only call it
2807 in the case of an actual error.
2808 (read_memory, write_memory): call memory_error.
2809 (core_fetch_registers): Register section name is ".reg".
2811 coredep.c: Remove a bunch of crud now that all this file does
2812 is pull the registers out of a core file.
2813 (fetch_core_registers): Rewrite to actually work, I hope.
2815 dbxread.c: Use a.out.gnu.h, not system a.out, now.
2816 Replace index() with strchr(). Remove all the pre-BFD macro
2817 definitions for accessing the symbol file.
2818 (struct dbx_symfile_info): Encapsulate the information that
2819 dbx_symfile_init needs to pass to dbx_symfile_read in this
2822 (dbx_new_init, dbx_symfile_init, dbx_symfile_read,
2823 dbx_symfile_discard): Rearrange symbol file reading to divide
2824 the format-specific part from the format-independent part,
2825 leaving the format-independent part such as file name expansion
2826 and opening in symtab.c. This replaces
2827 partial_symbol_file_open and partial_symbol_file_read.
2828 Symbol_file_read, add_file, add_file_target_command,
2829 add_file_addr_command move to symtab.c. Pass an explicit
2830 "mainline" flag for when reading the main symbol table, rather
2831 than relying on the offset address to be zero or nonzero.
2833 (dbx_symfile_read): Don't allow void *'s to be printed as
2835 (SWAP_SYMBOL): Use bfd routines to byte-swap the symbols.
2836 (ADD_PSYMBOL_TO_LIST): Make the "function call rather than
2837 macro" debug version really work.
2838 (read_dbx_symtab): Remove unref'd parameter inclink.
2839 Avoid swapping N_SLINE symbols, for speed.
2840 Merge N_TEXT!N_EXT case with the other external symbol
2841 definitions' case. Add comments.
2842 (start_psymtab): Allocate the symfile name in the psymtab on
2843 the psymbol_obstack, rather than using the caller's storage.
2844 (end_psymtab): Only allocate a dependencies list if there are
2846 (psymtab_to_symtab_2): Use BFD when reopening file to read
2847 its symbols for real.
2848 (read_struct_type): Add FIXME comments where it needs work
2850 (read_huge_number): Add FIXME about overflows.
2851 (read_range_type): Add FIXME about comparing a long to 1<<32.
2853 * coffread.c: Minor changes to move things closer to the new
2854 regime with symtab.c and dbxread.c Major work is still needed
2857 * exec.c (exec_file_command): Remove old variables (see core.c
2859 (xfer_memory): If memory transfer is right at the end of a
2860 section, don't lose.
2862 * findvar.c (get_saved_register): If value is in a real
2863 register, LVAL is lval_register, not lval_memory.
2865 frame.h: Declare print_sel_frame and record_selected_frame.
2867 gdb-int.texinfo: New file, for GDB internals documentation.
2868 Very simple, unformatted doc of cleanups is there for now.
2870 gdbcore.h: Remove obsolete variables that described a.out
2871 section addresses and offsets. (See core.c above.)
2872 Declare fetch_core_registers and registers_fetched.
2874 getopt.c: Declare char *alloca(); even on SPARC.
2876 infcmd.c (run_command): Call target_kill rather than
2878 (step_command, next_command, stepi_command, nexti_command):
2879 Declare from_tty parameter even though we don't use it.
2880 (run_stack_dummy): argument BUFFER is a char array, not
2881 a pointer to REGISTER_TYPE.
2882 (finish_command): using_struct_return needed a value *,
2883 not a struct symbol *.
2885 * infptrace.c (child_xfer_memory): To avoid dependency on
2886 where sections are in memory, try PT_WRITE_D and if that fails,
2887 try PT_WRITE_I. Most Unixes don't care which you use.
2889 * infrun.c (step_resume_break_shadow): Change to array to
2890 match other breakpoint shadow storage.
2891 (clear_proceed_status): Pass address of bpstat to
2892 bpstat_clear, not the bpstat itself.
2893 (child_create_inferior): FIXME comment about if the child
2895 (start_inferior): Remove old function.
2896 (child_open): Use target_kill rather than kill_inferior.
2897 (wait_for_inferior): Ditto.
2898 (insert_step_breakpoint, remote_step_breakpoint): Use
2899 new step_resume_break_shadow.
2901 * inftarg.c (child_wait): If all child processes die,
2902 pretend that the one being waited for exited with signal 42.
2904 * main.c (command_line_input): When scanning for comments,
2905 don't coredump on unclosed quotes.
2906 (quit_command): Use target_kill rther than kill_inferior.
2907 (_initialize_main): Rename class_user from "user" to
2910 * printcmd.c (print_command_1): Initialize "fmt" if no format
2911 is specified by the user.
2912 (print_frame_args): Only add to args_printed if we are
2913 actually fetching args from the stack (avoiding undefined
2915 (_initialize_printcmd): Remove bogus \{ from string.
2917 * remote-eb.c (eb_open): Avoid coredump on no argument.
2919 * remote-nindy.c: Bring out of Intel environment into new
2920 target environment. Remove all conditional compilation on
2921 I80960. Massive hacking throughout.
2922 (nindy_xfer_inferior_memory): New routine stolen from
2924 (nindy_create_inferior): New routine pieced together, probably
2925 not quite working yet.
2926 (nindy_ops): New target_ops struct for nindy.
2928 * remote-vx.c: Use write_memory rather than target_write_memory
2929 to get error checking.
2930 (vx_add_file_command, vx_open): Use symbol_file_add rather than
2932 (vx_create_inferior): Use target_terminal_ours...
2934 * signame.c (_initialize_signame): Always initialize, since
2935 we need the table for things other than psignal.
2937 * solib.c (solib_add): Use symbol_file_add, not add_file.
2938 (solib_address): Return boolean result rather than struct
2939 pointer which nobody else knows the type of.
2941 * sparc-tdep.c, valops.c: Use write_memory rather than
2942 target_write_memory, to get error checking.
2944 * stack.c (locals_info, catch_info, args_info,
2945 get_selected_block, frame_command, up_command): Use
2946 target_has_stack, rather than have_inferior_p or
2949 * sun3-xdep.c (fetch_core_registers): Rewrite for new BFD regime.
2951 * symfile.h: New file, defining the interface between the
2952 generic and object-file-specific symbol reading code.
2954 * symtab.c: Move generic symbol-reading interface to symtab.c,
2955 from dbxread.c, coffread.c, mipsread.c, etc. Add symtab_fns
2956 table to map BFD targets to symbol-reading modules in GDB.
2957 Change index to strchr.
2958 (lookup_struct_elt_type): Use error() rather than hand-made
2959 simulations thereof.
2960 (lookup_partial_symbol): Speedup slightly when length == 0.
2961 (symbol_file_add): New function.
2962 (symbol_file_command): Call it.
2963 (symfile_open, symfile_init): New function.
2964 (add_file_target_command, add_file_addr_command): moved from
2967 * target.c (target_command): use target_kill.
2969 * target.h (target_files_info): Don't declare, never called
2972 * tm-sun2.h, tm-sun3.h (STACK_END_ADDR): Use system include
2973 files to determine stack end address.
2975 * valarith.c (value_x_binop, value_x_unop): Change error message
2976 to be more useful. Pass proper argument to value_struct_elt.
2978 * valops.c (value_assign): FIXME comment that long long
2979 bitfields will break here.
2981 * Makefile.dist: Add symfile.h, remote-nindy.c, remote-eb.c.
2982 Update `make saber_gdb' to work better.
2984 * TODO: A woman's work is never done.
2986 * cplus-dem.c, environ.c, inferior.h, infrun.c, inftarg.c,
2987 main.c, obstack.c, printcmd.c, remote-eb.c, remote-nindy.c,
2988 remote-vx.c, remote.c, solib.c, source.c, sparc-pinsn.c,
2989 sparc-tdep.c, sparc-xdep.c, symmisc.c, symtab.c, symtab.h
2990 target.c, terminal.h, tm-sparc.h, tm-sunos.h, utils.c,
2991 valops.c, valprint.c, exec.c: Lint.
2994 Wed Dec 12 23:44:15 1990 John Gilmore (gnu at cygnus.com)
2996 Continuing Intel 960 port merge of GDB.
2998 * Makefile.dist: Merge i960 "nindy-share" files. Rename
2999 malloc.h to gmalloc.h to avoid name conflicts in /usr/include.
3000 Don't ship gdb.dvi in tar file. Link gdb with init.o, not init.c.
3001 Wack over "make depend" so it handles files in subdirectories
3002 vx-share, nindy-share, bfd, and in the current directory.
3004 * blockframe.c (get_prev_frame_info): Remove fatal error
3005 if stack not defined.
3007 * core.c (core_open, core_detach): New functions that handle
3008 the old "core-file" command as "target core" and "detach" instead.
3009 (core_file_command): Call them.
3010 (core_xfer_memory): Use common routine xfer_memory.
3012 * dbxread.c: Include a.out.gnu.h, not system a.out.h.
3013 dbxread now uses bfd for everything but symbol reading itself.
3014 BFD internals are used to drag out the relevant file offsets.
3015 (partial_symbol_file_open): Change args all around for BFD.
3017 * symtab.c: Rename "value" to "val" everywhere, so we can
3019 (symbol_file_command): New command, moved from dbxread.c
3020 and coffread.c. It uses BFD to read the file, then vectors
3021 based on its type, to dbx or coff symbol readers.
3022 * symtab.h: Extern a few vars for symbol_file_command.
3024 * target.h: Breakpoint takes a char * save area, not a char **.
3026 * valprint.c (val_print): When unpacking bitfields, offset
3027 the address in gdb of the value, if it is declared with a shorter
3028 type. Remove the last "runtime kludge test" of host byte order.
3030 * utils.c: Remove old my_bfd_read routine.
3032 * stack.c (frame_info): Use target_has_stack. Print program counter
3033 register's actual name rather than "pc", since it's called the
3034 "ip" (instruction pointer) on the i960 (sigh).
3036 * target.c (target_command): Add command for selecting a target
3037 type and calling its open routine. This is used for initiating
3038 communication with a particular target, in a generic way.
3040 * tm-i960.h: Update for modern gdb. Remove semicolons from
3041 various macros. Handle reading struct return convention, and
3042 error-out attempts to return structs with the "return" command.
3043 Be sure gdb doesn't think we know how to call functions in the
3046 * i960-tdep.c: Rename FRAME_CHAIN_VALID and FRAME_FIND_SAVED_REGS
3047 to i960_xxx in lower case.
3048 (arg_address): Circumvent errors due to LOC_ARG_BLOCK
3049 not being defined yet.
3051 * remote.c (remote_open): Call start_remote to initialize
3052 wait_for_inferior during open.
3053 (remote_xfer_inferior_memory): Return length written rather
3056 * remote-vx.c (target_command -> vx_open): Use new generic
3058 * remote-eb.c, inftarg.c, exec.c: ditto.
3060 * infrun.c: Fix comments.
3061 (attach_program -> child_open): Use new generic target command.
3062 (wait_for_inferior): Clear saved register values before target_wait,
3063 so target_wait can set some of them if convenient.
3065 * infptrace.c (fetch_inferior_registers, store_inferior_registers):
3066 Return success indicator, not void.
3067 (child_xfer_memory): Avoid fetching initial word if we'll
3068 overwrite it anyway.
3070 * infcmd.c (attach_command): Use new generic target open routine.
3071 (_initialize_infcmd): Update doc on attach and detach commands.
3072 (do_registers_info): Merge in a byte-order problem as a FIXME
3075 * findvar.c (find_saved_register): Avoid problem in current frame.
3076 (read_relative_register): Ditto.
3077 (write_register): Convert byte order on the way out.
3079 * exec.c (file_command): Add.
3080 (add_to_section_table, exec_command): Use new bfd_map_over_sections.
3081 (xfer_memory): Common function between core_xfer_memory and
3083 (exec_xfer_memory): Use it.
3085 * pn-opcode.h: Document that a "PN" is a Gould PowerNode.
3087 * breakpoint.c, breakpoint.h, symtab.h, value.h, frame.h, utils.c,
3088 valops.c, stack.c, target.c, sparc-xdep.c, source.c, printcmd.c,
3089 infcmd.c, i960-pinsn.c, eval.c, defs.h: lint and gcc -Wall.
3091 Sun Dec 2 16:45:06 1990 John Gilmore (gnu at cygnus.com)
3093 Merge Intel 960 port of gdb, continuing...
3095 * dbxread.c (partial_symbol_file_open, partial_symbol_file_read,
3096 symbol_file_command): Pass from_tty arg to hush 'em up.
3098 * coffread.c (symbol_file_command): Avoid output if from_tty != 1.
3099 Add magic numbers for 960 COFF format.
3101 Fri Nov 30 09:18:20 1990 John Gilmore (gnu at cygnus.com)
3103 Merge Intel 960 port of gdb, from Intel "1.2" release.
3105 CHANGE_LOG entries from their port, which was based on
3108 Thu Sep 6 11:02:22 PDT 1990
3109 Remove temp file if download is interrupted.
3111 Wed Aug 1 09:08:33 PDT 1990
3112 Now uses binary protocol to talk to NINDY.
3113 Old hex protocol (NINDY 2.13 and older) supported with -O switch.
3114 Times out after 5 seconds when trying to talk to NINDY.
3116 Tue May 29 12:54:49 PDT 1990
3117 Added variable baud rate (-b switch).
3118 Source code reorganization.
3120 Thu Apr 26 11:09:55 PDT 1990
3121 More cleanup of batch mode; specifically, execute "-s", "-e", and
3122 "-se" switches as soon as they are encountered on the invocation line.
3124 Fri Apr 20 13:47:15 PDT 1990
3127 Thu Apr 19 09:54:28 PDT 1990
3128 Add 'reset' command.
3130 Wed Apr 18 09:48:07 PDT 1990
3131 After opening remote tty, wait for 1 second to go by without input
3132 from it before trying to talk to NINDY (fixes problems with the
3133 Heurikon HK80/V960E).
3135 Mon Apr 4 16:33:05 PDT 1990
3136 Some output was not being suppressed in 'batch' mode.
3138 Thu Mar 22 15:31:11 PST 1990
3139 Ask user if old symbol table should be deleted when new file is
3142 Allow user to run a program downloaded before gdb960 was brought up.
3144 Correct "exec-file" help message for i80960 context.
3146 Correct bug in calculating user space address: could occasionally
3147 corrupt user program.
3149 Make sure to zero low-order bits in rip's because of bug in 960CA
3150 A-step part: could cause operation faults when "next"ing across
3153 Correct bug that made it impossible to get source line numbers for
3154 code loaded at addresses higher than 0x7fffffff.
3156 Wed Jan 10 12:43:22 PST 1990
3157 Open remote tty for exclusive use.
3159 Fri Jan 5 12:14:42 PST 1990
3160 Correct disassembly (CA manual was right after all):
3161 opcode for sysctl is 0x659
3163 Mon Oct 23 12:03:04 PDT 1989
3164 Use G960BASE and G960BIN environment variables to find 'sx' utility.
3166 Mon Oct 16 14:15:09 PDT 1989
3167 "sfr0"-"sfr31" should have been named "sf0"-"sf31"
3169 Mon Oct 2 15:56:31 PDT 1989
3171 Added 960CA disassembly support.
3173 To simplify maintenance:
3174 - eliminated use of symblic links on pinsn.c: use i960-pinsn.c
3176 - eliminated opcode.h: incorporates tables into i960-pinsn.c
3177 - moved 960-specific routines from i960-pinsn.c to i960-md.c
3178 - made disassembly interface identical to that in gdmp960.
3182 Wed Nov 28 21:32:48 1990 John Gilmore (gnu at cygint)
3184 * target.h: Allow targets to stack. Add target_has_memory,
3185 _registers, etc. Restructure memory access and "info files"
3186 to walk the target stack.
3187 * exec.c, core.c, inftarg.c, remote.c, remote-vx.c, remote-eb.c,
3188 target.c: Change tables to match target.h.
3189 * inflow.c (child_mourn_inferior): pop child_ops.
3190 (generic_mourn_inferior): Use new has_stack flag.
3191 * infptrace.c (child_xfer_memory): New memory regime.
3192 * inftarg.c (child_files_info): New "info files" regime.
3193 * remote-eb.c: New memory regime, new info files.
3194 * remote-vx.c: New memory regime, new info files. Now use
3195 separate targets for VxWorks attachment to machine, and
3196 actually running a process under VxWorks, since one has
3197 stack & execution & regs and the other doesn't.
3198 * remote.c: New memory regime, new info files.
3199 * sparc-xdep.c (fetch_core-registers): New memory regime.
3200 * target.c: New routines and support for stacked targets,
3201 new memory regime, new info files regime.
3204 Generalize section handling for an arbitrary number of sections,
3205 including use of the new BFD (binary file) library.
3206 * gdbcore.h: Add struct section_table.
3207 * exec.c (build_section_table): Iterate all sections and
3208 record what gdb needs to know about them.
3209 (exec_command): Use it.
3210 (exec_xfer_memory): Use the table.
3211 (exec_files_info): Print the table.
3212 * core.c (core_file_command, core_xfer_memory, core_files_info):
3214 * source.c (find_source_lines): Use bfd_get_mtime.
3215 * dbxread.c: Quick changes to make it compile with new BFD.
3216 * utils.c (error): Avoid using bfd_error in generic routines.
3218 * core.c (core_fetch_registers): Get from the ".regs" section of
3220 * sparc-xdep.c (fetch_core_registers): Use the .regs info.
3222 * inferior.h (attach_flag): Export.
3223 * infcmd.c (run_command): use new target_create_inferior.
3224 * infrun.c (child_create_inferior): Don't return result.
3225 * Makefile.dist (VERSION): 3.91.4.
3227 Fri Nov 23 28:15:38 1990 John Gilmore (gnu at cygint)
3229 * breakpoint.c (bpstat_num): Handle breakpoints which have
3230 since been deleted, such as temporary breakpoints.
3231 infcmd.c (program_info): ditto.
3233 * core.c (core_file_command): Display the frame where the core
3238 * remote-vx.c (target_command): Merge in target command from
3239 targ-vx.c. A few other cleanups.
3241 * TODO, Projects: Lots more stuff to do...
3243 Fri Nov 23 18:15:38 1990 John Gilmore (gnu at cygint)
3245 Massive changes to wall off the remote-debugging interface
3246 behind a function vector. The port to handle VxWorks targets
3247 is also part of this.
3249 All files: Replace references to renamed functions,
3250 remove references to remote_debugging, remove references to
3251 have_include_file, have_core_file in favor of target_has_stack,
3252 target_has_memory, etc.
3254 * Modularize the breakpoint interface.
3255 breakpoint.h (BREAKPOINT_MAX): New define sets max length of
3256 a breakpoint instruction.
3257 breakpoint.c: struct breakpoint's shadow_contents now sized as
3259 (insert_breakpoints): Vector to target to install breakpoints.
3260 (remove_breakpoints): Vector to target here too.
3261 Remove REMOTE_SA_SPARC kludges and other remote_debugging.
3262 sparc-tdep.c (single_step): Use new breakpoint interface for
3263 the single-step breakpoints.
3264 mem-break.c (memory_insert_breakpoint, memory_remove_breakpoint):
3265 New file, contains routines to insert and remove breakpoints by
3266 reading out the old contents and later replacing them. This is
3267 how ptrace breakpoints work, and many remote systems as well.
3269 * tm-vxworks68.h: New config file, overrides a few things for
3270 Wind River's preferences.
3272 * target.h: New file, for transfer vector used to talk to the
3273 inferior (child, attached, core, exec, remote, etc). All accesses
3274 to the thing being debugged should come through these vectors.
3275 target.c: New file, routines to handle transfer vector.
3276 (various files): Add transfer vectors XXX_ops for the various
3277 targets and pseudo-targets (core files, etc) we support.
3279 * breakpoint.c (bpstat_stop_status): Further explorations of
3280 watchpoints and why things don't work all the time.
3281 (bpstat_alloc): New fn to allocate a bpstat and chain it.
3283 * config.gdb: Only add "source ${srcdir}/.gdbinit" to
3284 the local gdbinit if it doesn't already have it.
3286 * core.c (core_ops): add and install.
3287 Allow core debugging without exec file.
3289 * dbxread.c (free_and_init_header_files): Merge two fns.
3290 (end_symtab): Free named symbol table when a new version comes in.
3291 (read_dbx_symtab): Relocate all kinds of symbols with base
3292 address. First step toward handling different text, data, bss
3294 (add_file_addr_command): Renamed add_file_command.
3295 (add_file_command): Vector to remote handler.
3296 Add "load" as an alias for "add-file" command.
3298 * defs.h: Allow "volatile" to be used in non-ANSI; use it for
3299 non-returning functions.
3301 * exec.c: Add exec_ops, and push it as a target when an exec
3304 * infcmd.c (run_command): Pass executable file name and arg list
3305 separately when starting an inferior. Permit "run" when no exec
3306 file is specified, for VxWorks.
3307 (detach_command): Move to child_detach in inftarg.c.
3309 * inftarg.c: New file. Unix-child-specific routines, and the
3310 child_ops structure.
3312 * inferior.h (registers): Export "registers" as the way for
3313 target dependent register handlers to find gdb's local copy of
3314 the registers. Rename "stop_after_attach" to "stop_soon_quietly"
3315 since it is now used by places that want wait_for_inferior to
3316 handle the grunge but want to see every trap from the inferior.
3318 * inflow.c (create_inferior): Pull out, and merge into infrun.c.
3319 Eliminate remote_debugging hooks in terminal handling.
3321 * infrun.c: Replace start_inferior with child_create_inferior.
3322 Move all the hair of Unix shells and ptrace idiosyncracies into
3323 child_create_inferior, so remote handlers don't have to deal.
3324 Remove running_in_shell. Rename stop_after_attach to
3325 stop_soon_quietly, and use it in a few other places where we want
3326 to just call wait_for_inferior and get control back on the first
3327 trap. trap_expected now never takes a value > 1.
3328 (init_wait_for_inferior): Initialize static vars when a new
3331 main.c (gdbinit): Add new hook for .gdbinit file name, let
3332 it be overridden by config files as GDBINIT_FILENAME.
3333 (DEFAULT_PROMPT): Add new hook for overriding (gdb) prompt.
3334 Both of these are used for VxWorks gdb.
3336 mcheck.c: rename include file "gmalloc.c" to avoid problems
3337 with system include file "malloc.c".
3339 param-no-tm.h: New include file, same as param.h but does not
3340 include the default "tm.h" file. This is used in files where
3341 the target is known, e.g. remote-eb.c or sparc-xdep.c.
3343 param.h: Now just a shell that includes tm.h and param-no-tm.h.
3345 remote-vx.c: New file, VxWorks remote debugging support. Uses
3346 RPC routines that are shared with the target system, in directory
3349 remote.c: Vectorize remote interface.
3351 source.c: Globalize source_path, and make an alias "l" for "list"
3352 since we now have the "load" command.
3354 sparc-xdep.c: Use new param-no-tm.h.
3356 symmisc.c (free_named_symtab): Add new function from Wind River.
3357 However, ifdef it out for now while we think about what it should
3360 tm-sun3.h, xm-sparc.h, xm-sun3.h, xm-symmetry.h: Move
3362 the xm- file, and change its name to CHILD_PREPARE_TO_STORE, since
3363 non-Unix-children handle this with their own code in the target
3366 Makefile.dist: Roll version to 3.92.3. Add vx-share stuff to
3367 source and target lists. Add vx-share to default list of include
3368 directories. Add new files to src and target lists: mem-break,
3369 target, inftarg, remote-eb, remote-vx, targ-vx. Be sure the
3370 ${srcdir} versions of munch and createtags are used.
3372 * valops.c (find_function_addr): Split out of call_function.
3373 (call_function_by_hand): Rename call_function; this function
3374 calls functions in the target by laboriously patching the target
3375 word-by-word with the right stack, args, regs, etc.
3378 Mon Nov 5 17:29:10 1990 John Gilmore (gnu at cygint)
3380 Handle AMD 29000 a bit better.
3382 * remote-eb.c (readchar): Mask received char log to make it readable.
3383 (remote_start): Pass arguments down to executing program.
3384 Make startaddr unsigned.
3385 infrun.c (start_inferior): Accept args, pass them to
3387 infcmd.c (run_command): Pass args down to start_inferior.
3389 * tconfig/am29k-aout, tconfig/am29k-coff: New files specifying
3390 the target object file format.
3391 tm-29k.h: Pay heed to COFF_ENCAPSULATE.
3393 * am29k-pinsn.c (print_insn): Print 0x on hex numbers in disassembly.
3394 am29k-tdep.c (examine_prologue): Better checking of function prefixes.
3396 Sun Oct 7 18:20:45 1990 John Gilmore (gnu at cygint)
3398 * Makefile.dist (VERSION): Roll version to 3.91.9 and freeze.
3399 * TODO: We did a few things, we have more to do though.
3401 * xm-sparc.h (CLEAR_DEFERRED_STORES): Define.
3402 * inflow.c (inferior_died): Clear deferred stores.
3404 * Debug problems with dummy frames and calls to the inferior.

3407 (sparc_frame_find_saved_regs): Simplify and fix what we find.
3408 (sparc_push_dummy_frame): Simplify and fix what we push.
3409 (sparc_pop_frame): Slightly more hair here, deciding whether
3410 we are restoring a saved PC or returning to a return address in %i7.
3411 * sparc-xdep.c (read_inferior_registers): Debug if valid reg is read.
3413 * utils.c (xmalloc, xrealloc): Return type depends on __STDC__.
3414 * symtab.h (xmalloc): ditto, for obstack_chunk_alloc.
3415 * obstack.h (chunkfun): ditto.
3416 * defs.h (xmalloc, xrealloc): ditto
3418 * utils.c (quit): Grab the terminal from the child if necessary.
3420 * inflow.c (term_status_command): Rename to term_info, change
3423 * sparc-pinsn.c (print_insn): Disassembly prefers real instructions.
3424 (is_delayed_branch): Speed up.
3425 * sparc-opcode.h: Add ALIAS bit to aliases. Fix up opcode tables.
3426 Still missing some float ops, and needs testing.
3428 * Support for input and output radixes other than base 10
3429 * defs.h (input_radix, output_radix): Declare.
3430 * expread.y (yyparse, parse_number): Handle changes of input
3431 radix, and ambiguous names-or-numbers in radixes >10.
3432 * printcmd.c (print_scalar_formatted): Print formatted hex
3433 numbers in varying column widths.
3434 * valprint.c (val_print): Use output_format to print scalar ints.
3435 (set_input_radix, set_output_radix, set_radix): Create.
3436 (set_output_radix): Set output_format from output_radix.
3437 (_initialize_valprint): add `set radix' but leave the others off.
3439 * main.c (execute_command): Let stupid questions be turned off.
3440 (_initialize_main): Handle "set stupidity", etc.
3442 * main.c, inflow.c, inferior.h, frame.h, command.c, defs.h,
3443 sparc-pinsn.c, sparc-xdep.c, value.h, valops.c, values.c: Lint.
3445 Tue Oct 2 11:20:02 1990 John Gilmore (gnu at cygint)
3447 * TODO, Makefile.dist, ChangeLog: Freeze for 3.91.8 release.
3448 bfd stuff is still screwed up, but with some manual work, it
3451 * breakpoint.c (bpstat_do_actions): Start over if a command
3452 proceeds the inferior, since the inferior will have stopped and
3453 will need to have its new stop-actions taken care of.
3455 * dbxread.c (read_struct_type): Expression gives Sun3 4.0.3
3456 compiler fits, simplify it.
3458 * gdb.texinfo (directory command): Doc new dir command.
3459 source.c (directory_command): "dir" now puts things on the front
3460 of the path, moves dups up front, and handles multiple names
3461 on the command line, inserting each one in order. It also
3462 blows away cached line and full_filename info.
3464 * stack.c (backtrace_command): Skip "more stack frames follow"
3467 * Change #ifndef HAVE_VPRINTF to #define MISSING_VPRINTF in
3468 xm-convex.h, xm-hp300bsd.h, xm-isi.h, xm-merlin.h, xm-news.h,
3469 xm-np1.h, xm-pn.h, xm-pyr.h, xm-symmetry.h, xm-umax.h, xm-vax.h.
3470 The only odd one was Gould NP1, which had defined vprintf to
3473 * Merge Ted Goldstein <tedg@Eng.sun.com>'s changes for epoch.
3474 printcmd.c (print_command_1): Pass 'inspect' flag down as a global
3475 variable, inspect_it.
3476 valprint.c (print_string, val_print): Use the global inspect_it
3477 to indicate whether to print in Epoch style or normal style.
3479 Mon Oct 1 23:55:26 1990 John Gilmore (gnu at cygint)
3481 * printcmd.c (call_command): add an alias for the "print" command
3482 which runs expressions and doesn't print the result if void.
3483 (print_command_1): implement it.
3485 * command.c: Remove #if 0'd code. Initialize all the fields
3486 in add_cmd (). Rename do_nothing_command to
3487 not_just_help_class_command, and make it externally visible.
3488 command.h: add user_commands to struct.
3489 * main.c (define_command): Don't overload c->function with a char
3490 string as well as a function pointer.
3492 * eval.c (evaluate_subexp): Reinstall tiemann changes to
3493 calling convention of value_struct_elt () that got dropped in
3496 * tm-sparc.h (FRAME_FIND_SAVED_REGS): move to sparc-xdep.c.
3497 sparc-tdep.c (sparc_frame_find_saved_regs): ditto.
3499 * tm-sparc.h (POP_FRAME): replace some constants with defines.
3501 * sparc-xdep.c (store_inferior_registers): defer stores to regs
3502 until a good time (e.g. when we are about to run the child),
3503 saving ptrace calls.
3504 * infrun.c (proceed): handle DO_DEFERRED_STORES.
3505 * tm-sparc.h: define DO_DEFERRED_STORES.
3507 * sparc-xdep.c (store_inferior_registers): when storing float
3508 registers, don't store stack regs too. When storing the SP,
3509 however, DO store the stack regs too. This fixes a bug in which
3510 the dummy frame is not recognized when a call_function finishes,
3511 because its frame pointer (in the stack regs) was never
3513 (read_inferior_registers): Mark WIM and TBR and FPS and CPS valid
3514 even though we don't know how to read them from an inferior.
3515 valops.c (call_function): Comment about storing SP.
3517 * infrun.c (save_inferior_status): Save away the original bpstat
3518 chain so it can be restored later. Install the copied version for
3519 use by whoever saved the status. It will be blow away by
3520 restore_inferior_status, and the original chain restored. This is
3521 important for people who have pointers into the original.
3523 * breakpoint.c, command.h, copying.awk, dbxread.c, defs.h,
3524 findvar.c, frame.h, obstack.h, obstack.c, inflow.c, value.h,
3525 main.c, printcmd.c, sparc-tdep.c, symtab.c, valprint.c: lint
3528 Fri Sep 28 20:32:46 1990 John Gilmore (gnu at cygnus.com)
3530 * Makefile.dist: Roll version to 3.91.8. Add bfd.h and bfdconfig.h
3531 temporarily to the makefile. Add am29k-opcode.h and WHATS.NEW.
3532 Add stuff.c and kdb-start.c to the OTHERS list for tar files.
3534 Fri Sep 28 19:12:12 1990 John Gilmore (gnu at cygint)
3536 * Merge Mike Tiemann's multiple inheritance changes from Sun.
3537 Store the baseclasses in a type struct starting from array element
3538 0 rather than from the unusual array element 1.
3540 dbxread.c: the above.
3541 (virtual_context): Add
3542 Read new debug information about which virtual function table
3543 a virtual function is from, and store it in fn_field.fcontext.
3545 symtab.h: Add fcontextt. Fix baseclass indices. Typo in
3546 TYPE_FN_FIELD_STATIC_P.
3548 symtab.c: the above.
3549 valops.c: the above. Handle pointer casts of object *'s.
3550 (search_struct_method): Add.
3551 (value_struct_elt): First arg is now a pointer to a value, and is
3554 valprint.c: the above.
3555 values.c (value_virtual_fn_field): Add type arg. Handle
3556 offsetting to the proper object when calling virtual fns.
3558 (baseclass_addr): Add valuep arg.
3560 * README: Document the current state of BFD config (missing).
3561 * TODO, ChangeLog, Makefile.dist: Roll version.
3562 * WHATS.NEW: Add summary of changes since 3.5.
3564 Thu Sep 27 16:23:12 1990 John Gilmore (gnu at cygint)
3566 * dbxread.c (read_struct_type): Clear bit vectors whenever
3568 symtab.c (B_CLRALL): define.
3570 * tm-sparc.h (STORE_RETURN_VALUE): Avoid clobbering types by
3571 using == rather than =. Huh... This fixes the dreaded problem
3572 wherein builtin_type_int becomes TYPE_CODE_FLT.
3574 * core.c (info_files): Show the inferior pid.
3576 * config.gdb: Avoid putting "dir" command into .gdbinit. GDB
3577 already knows how to look in the source directory.
3579 * Remove psymtab hair from many places. Remove duplicated code
3580 for searching symbol tables. Hide psymtabs from most places.
3581 Make it fast to get from a psymtab to its symtab.
3583 blockframe.c (blockvector_for_pc): Remove psymtab hair.
3584 coffread.c (psymtab_to_symtab): Rename to psymtab_to_symtab2.
3585 mipsread.c (psymtab_to_symtab): Rename to psymtab_to_symtab2.
3586 dbxread.c: export psymtab_to_symtab, make it work if called N times.
3587 (psymtab_to_symtab): Rename to psymtab_to_symtab2. Initialize
3588 new symtab completely. New psymtabs get symtab pointer
3589 initialized to zero. Remove MI warning printf.
3590 symtab.h: Comments. Add psymtab to symtab pointer.
3591 (PSYMTAB_TO_SYMTAB): New macro.
3592 symtab.c: use PSYMTAB_TO_SYMTAB. Add psymtab_to_symtab and export it.
3593 source.c: use PSYMTAB_TO_SYMTAB. Remove symtab version and
3595 stack.c (backtrace_command): Avoid pre-pass to read symbols, if
3597 (print_frame_info): Avoid special-casing symbols that have not yet
3600 * source.c (open_source_file): Quick path if we have already
3601 located the source file by its full name.
3603 * symtab.c (lookup_symbol): Use find_pc_symtab rather than
3604 find_pc_psymtab. When a name is found in the misc function
3605 vector, search the symbol table for its mangled name, not the
3606 name that the user typed.
3608 * bfd.h: Fix missing comment terminators, make #endifs match.
3610 * valarith.c (value_less): Handle unsigned int comparisons.
3611 Add FIXME about pointer compares, which assume host and target
3612 pointers are the same.
3614 * command.c (do_nothing_command): lint
3615 dbxread.c: lint. Remove sort_syms. Document C++ visibility info,
3616 fix comments on debug symbol format for visibility. Actually set
3617 visibility of symbols.
3618 main.c (echo_command): lint; use <readline/history.h>.
3619 tm-sparc.h (FRAME_FIND_SAVED_REGS): lint
3620 obstack.h (_obstack_blank): Rearrange pointer math to avoid
3621 pointing past end of allocated memory; saber complains.
3622 obstack.h: Declare the external functions that we use.
3623 valarith.h: use <string.h>
3624 solib.c (solib_add): lint.
3626 Fri Sep 21 17:05:19 1990 John Gilmore (gnu at cygint)
3628 * main.c (initialize_main): Default info_verbose to off, now that
3629 symbol reading is fast.
3630 (quit_command): Avoid clobbering exec_bfd while quitting.
3632 * Initial BFD (binary file diddling library) merger:
3633 coffread.c: Change AOUTHDR to struct exe_hdr.
3635 core.c: initialize initialized data at compile time.
3636 (core_file_command): Move from coredep.c, convert to bfd.
3637 (xfer_core_file): Convert to bfd.
3638 exec.c (exec_file_command): use bfd routines.
3640 mips-tdep.c: Remove exec_file_command and friends.
3643 * coredep.c: (fetch_core_registers) Convert core_file_command to
3644 fetch_core_registers.
3645 mips-xdep.c, sparc-xdep.c, sun3-xdep.c: ditto.
3647 * utils.c: (error): Bogus crap, FIXME, to print bfd errors.
3648 (my_bfd_read): More bogosity, which I don't think we call.
3649 (program_name): Remove this atrocity asap!
3651 Wed Sep 19 13:36:41 1990 John Gilmore (gnu at cygint)
3654 values.c: allocate_repeat_value was not clearing the
3655 optimized_out field.
3656 (value_static_field): minor stylistic fix (wrong macro was used).
3657 valops.c (value_struct_elt_for_address): didn't work for C++
3660 * signame.c (_initialize_signame): Initialize signal names once.
3662 * breakpoint.h, command.c, copying.awk, defs.h, environ.c,
3663 exec.c, frame.h, infcmd.c, inferior.h, main.c, munch, sun3-xdep.c,
3664 symtab.h, tm-29k.h, valprint.c, value.h, values.c: Lint.
3666 * remote-eb.c: Support user-settable baud rates on the serial port.
3668 * tm-sun3.h (PREPARE_TO_STORE): fix typo.
3670 Fri Sep 14 13:28:29 1990 John Gilmore (gnu at cygint)
3672 * tconfig/sun3os4: Remove warning about native assembler,
3673 since it also occurs in the xconfig file.
3675 * findvar.c (registers): Allocate some slop after `registers'
3676 to prevent stray accesses from trashing the next variable.
3678 * tm-68k.h (REGISTER_BYTES): Allocate the right number of bytes
3679 on the sun-3, by changing the #ifdef from `sun3' (which is not
3680 defined by cc) to `sun'. Symptom was trashed builtin_type_XXX
3681 vars, which happened to follow `registers' in the executable.
3683 * readline/history.c (history_search): Heed gcc-2's advice
3684 and parenthesize && inside ||).
3686 * am29k-opcode.h, am29k-pinsn.c, am29k-tdep.c, remote-eb.c,
3687 tm-29k.c: Insert FSF copyright headers.
3689 * remote-eb.c: Better comments.
3691 * Makefile.dist: Update to 3.91.6.
3692 * TODO: note PREPARE_TO_STORE problem.
3694 Thu Sep 13 09:52:33 1990 Jim Kingdon (kingdon at cygint)
3696 * stack.c (frame_info): Only use FRAME_FIND_SAVED_REGS if defined.
3698 * remote.c: Wrap the whole file in #if !defined (SPECIAL_REMOTE).
3700 * infrun.c (wait_for_inferior, at end): Don't set up
3701 prev_* if the inferior no longer exists.
3703 * inferior.h (CALL_DUMMY_LOCATION): New macro, to replace
3704 CANNOT_EXECUTE_STACK.
3705 valops.c (call_function): Use it.
3707 * tm-convex.h: Add CALL_DUMMY_LENGTH for use by PC_IN_CALL_DUMMY.
3709 * inferior.h (PC_IN_CALL_DUMMY): New macro.
3710 infrun.c (wait_for_inferior, 2 places): Use it.
3712 * values.c (value_being_returned): Only use
3713 EXTRACT_STRUCT_VALUE_ADDRESS if defined.
3715 * Move PREPARE_TO_STORE from xm-sun3.h to tm-sun3.h to do the
3716 right thing for remote-eb.c.
3718 * sun3-xdep.c: Remove extraneous call to remote_store_registers.
3719 * sun386-xdep.c, hp300hpux-xdep.c, sparc-xdep.c: Ditto.
3721 * blockframe.c: Put get_frame_saved_regs inside #if !defined
3722 (FRAME_FIND_SAVED_REGS).
3724 * findvar.c ({fetch,store}_registers): Check for
3725 REMOTE_{FETCH_STORE}_REGISTER macro.
3727 * findvar.c (get_saved_register): Add argument lval and
3728 change meaning of argument addr.
3729 findvar.c: Change calls to get_saved_register to reflect
3730 new calling convention.
3731 valops.c (value_assign): Use get_saved_register instead of
3732 find_saved_register.
3734 Sun Sep 2 12:40:20 1990 Jim Kingdon (kingdon at cygint.cygnus.com)
3736 * coffread.c (read_one_sym): Make temp_aux an AUXENT, not
3737 an (uninitialized) pointer to one. Use "&" when passing it
3740 Fri Aug 31 22:57:54 1990 Jim Kingdon (kingdon at cygint.cygnus.com)
3742 * coffread.c (getfilename): Use DGUX x_offset and x_name if
3745 * coffread.c (symbol_file_command): Put semicolon after
3747 Put safe_to_init_tdesc_context in #if defined (TDESC).
3748 Put #ifdef TDESCs in 1st column for non-ANSI cpp's.
3749 coffread.c: #include <sys/stat.h>.
3750 (read_coff_symtab): Typo: in_source_files -> in_source_file.
3751 Add missing ')' in check for "lc%" and friends. Remove
3753 Declare read_one_sym() at top of file.
3754 (read_file_hdr): Put in extra #ifdefs so MC68MAGIC and
3755 MC68WRMAGIC can have the same value without causing a duplicate
3758 Thu Sep 13 15:55:36 1990 John Gilmore (gnu at cygint)
3760 * Allow a Makefile to be built without building the
3761 tm and xm file links that screw up builds in subdirectories.
3762 This is done with `config.gdb none', then you can do things
3763 like `make gdb.tar.Z'.
3764 * tconfig/none: Config file for no target system
3765 * xconfig/none: Config file for no host system
3766 * config.gdb: If no TM or XM files are called out by the
3767 host or target file, don't make links for them.
3769 * cplus-dem.c: Add documentation.
3771 * dbxread.c (read_ofile_symtab): Turn a fatal error into a
3772 simple error, so the user's gdb doesn't crash due to some object
3773 file problem (e.g. somebody is rebuilding the file out from under
3776 * printcmd.c (print_address_symbolic): demangle the symbol.
3778 * Makefile.dist (OTHERS): Remove tdesc-lib because it has
3779 Motorola copyrights in it. Make "make gdb.tar.Z" work.
3780 (alldeps.mak): sort and uniq all results from this; duplicates
3781 hose gdb.tar.Z link building. Remove RCS files from
3782 tconfig and xconfig. Add config files for sun386. Add
3783 a few odd files to OTHERS and HFILES.
3785 Mon Sep 10 21:20:24 1990 John Gilmore (gnu at cygint)
3787 * Makefile.dist: Pull solib.c to tconfig/sun?os4.
3788 Roll version number to 3.91.5. Make lint work in bindir.
3790 * README: Document cross-debugging and new file structure.
3792 * blockframe.c: Lint. Include "value.h" to declare read_register.
3793 (find_pc_partial_function): remove duplicate line.
3795 * command.h: Lint. Declare error_no_arg and dont_repeat.
3797 * tm-news.h: Remove inadvertently duplicated stuff.
3799 * mipsread.c: Remove cache_pc_function stuff, now done cleanly.
3800 Clean up usage of misc_function_type. Declare some CORE_ADDRs.
3802 * config.gdb: Allow `config.gdb host target' form. Clean
3803 up previous change that printed bogus messages when you just said
3806 * core.c: #include "command.h" for lint.
3809 * main.c: Remove some casts of enums. Lint.
3816 * printcmd.c (initialize_printcmd): Fix thinko in inspect cmd.
3818 * sparc-tdep.c (isannulled): Take instruction as parameter, don't
3819 read it from memory. This will allow us to save ptrace calls
3820 eventually. Changed caller single_step too.
3822 * sparc-xdep.c (fetch_inferior_registers): Avoid reading regs
3823 that we aren't going to use, saving many ptrace calls, especially
3824 when watchpointing or single stepping. Use some #define's for
3826 (store_inferior_registers): Ditto.
3827 (core_file_command): Use some #define's for constants.
3829 * tm-sparc.h: Add #define's for some register numbers, so we
3830 can eliminate the use of random constants in sparc-xdep.c.
3832 * stack.c (frame_command, print_frame_info, up_command,
3833 down_command) Remove frame_changed, since it
3834 causes a bug and doesn't seem to do anything useful. In some
3835 places it was used as a flag, in others as a stack level (?).
3837 * utils.c: Use MISSING_VPRINTF rather than HAVE_VPRINTF, so the
3838 default is to use the portable (vprintf) version rather than the
3840 * xm-news.h (MISSING_VPRINTF): Add.
3842 * valprint.c (val_print): Demangle fancy vtbl printouts. Lint.
3844 Sat Sep 8 00:24:12 1990 John Gilmore (gnu at cygint)
3846 * Remove stuff that forces -Bstatic linking of gdb, and warnings
3847 about linking debugged programs -Bstatic in the sun?os4 config
3848 files in tconfig and xconfig subdirectories.
3850 * main.c (main): Remove unreached exit(0) now that we exit
3853 * Create TODO file for online bug list. There are too many
3854 "little" bugs to keep track of on paper.
3856 * Change Projects file to refer to bug-gdb@cygnus.com
3857 rather than kingdon@ai.
3859 Fri Sep 7 23:35:15 1990 John Gilmore (gnu at cygint)
3861 * Makefile.dist (VERSION): 3.91.4 now.
3863 * symtab.c (init_misc_bunches): Rename from init_misc_functions.
3864 (condense_misc_bunches): Add sanity check that misc_count is
3865 the same as the number of symbols in the bunch.
3867 * coffread.c: rename init_misc_bunches. Pass an argument
3868 to condense_misc_bunches (a zero).
3870 * dbxread.c (partial_symbol_file_read): Call init_misc_bunches
3871 every time we are called; don't rely on our caller to do it.
3872 (add_file): Remove call to init_misc_bunches.
3874 * mipsread.c: Only warn, don't error, if unknown symbol types.
3875 This keeps an old gdb from falling on its face if it sees newly
3876 extended symbol info. Rename init_misc_bunches.
3878 Fri Sep 7 22:58:15 1990 John Gilmore (gnu at cygint)
3880 * Merge in changes from Per Bothner for DECstations and other
3881 MIPS stuff. The rest is Bothner speaking:
3883 The next message is a merger of Alessando Forin's mips port with
3884 mine. I've tried to use my good if biased judgment to get
3885 the best of both. It *does* need testing.
3887 Some of the changes are general, *not* mips-specific.
3890 Didn't believe in little-endian bit order.
3891 There are still inconsistencies about whether flags
3892 like BITS_BIG_ENDIAN are integer (#if ...) or
3893 boolean (#ifdef ...). I tried to paper over them.
3895 dbxread.c,coffread.c,mipsread.c,symtab.c,symtab.h:
3896 Moved some misc_function code that was common to
3897 {dbx,coff,mips}read.c to symtab.c.
3898 In the process, I think I cleaned things up a bit.
3899 At the same time, moved obsavestring and obconcat to symtab.c.
3902 Removed obsolete condense_addl_misc_bunches (use
3903 condense_misc_bunches(1) instead).
3906 Needed to include <sys/dir>, at least on DECstations.
3908 valops.c, mips-tdep.c, tm-mips.h:
3909 Added PUSH_ARGUMENTS macro to support funny argument-pushing
3910 conventions (when STACK_ALIGN is insufficient).
3911 Needed on mips, where doubles need 8-byte alignment,
3912 but ints only need 4.
3915 Removed cruft that was not being used.
3916 Merged in many fixes (most from Frank Yellin, fy@lucid.com).
3919 Print $ before register-names (I think that makes things a little
3921 Never print two instructions, even if one delays.
3922 Removed hex-disassemble set_cmd. (This is not mips-specific,
3923 so I think the argument is whether it is generally worthwhile or not.
3924 I'm inclined to think not, given how easy it is to
3925 convert between radixes in gdb.)
3928 This is basically Alessando's code.
3929 It doesn't use obstacks; I changed it to use obstacks
3930 in a few minor places where using malloc causes a
3931 memory leak. (Probably, more places could/should be changed.)
3932 I added record_misc_function where it was missing.
3933 In symbol_file_command and add_file_command, I tried
3934 to make the code consistent with more recent versions.
3935 Minor sylistic changes in parse_procedure.
3936 Make a .gdbinfo. psuedo-symbol point back to the real
3937 procedure symbol (using the isym field).
3940 This is basically from my port, but with a lot of details
3941 and a number of routines merged in from Alessando's version.
3942 I basically used my code "raw" backtrace (use heuristics
3943 from the actual code, rather than symbol table info) - though
3944 the idea is Alessandro's. I feel my code is a little cleaner
3945 here, particularly in being a little more flexible, such as being
3946 able to handle gcc-produced code (which it now can).
3947 It also doesn't do frame caching (which is not useful
3948 more recent gdb versions).
3949 I also used my code for push_/pop_dummy, more or less.
3950 I tried to incorporate AF's code for testing sigtramp
3951 while backtracing; I probably got it wrong.
3952 Added mips_print_register, which tries to scrunch as much
3953 information as possible on a screen...
3954 Removed the skip-prologue set_cmd. As with hex-disassemble (see
3955 under mips-pinsn.c), I don't see anything mips-specific here,
3956 and I don't see it being all that useful anyway.
3959 Added a $fp psuedo-reg distinct from $fp (nice for gcc).
3960 Use more register names (rather than hard-cases numbers).
3962 Thu Sep 6 18:33:15 1990 John Gilmore (gnu at cygint)
3964 * Hack up 3.90.11 changes:
3966 * Makefile.dist (depend): parameterize $(GCC).
3967 Add solib.c and solib.o.
3968 (readline): Fix vpath for both absolute or relative SRCDIR.
3970 * blockframe.c: Fix from Schaefer@asc.slb.com for shared libs.
3971 Also, let the part I didn't understand at least compile so
3972 I can test the rest. FIXME.
3974 * dbxread.c: Fix thinko using strcmp.
3975 (init_psymbol_list): declare static.
3976 (partial_symbol_file_open): Comment cleanups better, avoid
3977 cleaning up the string table since the caller will do that.
3978 Move the stat for mod time into symbol_file_command, temporarily.
3979 (There should be a mod time for each symbol file, eventually,
3980 to control its rereading. FIXME.)
3982 * infptrace.c (PT_WRITE_D): use same value as PT_WRITE_I for
3983 SunOS, which gives error for shared libs otherwise. (From
3984 Schaefer, probably FIXME needs work for portability.)
3986 * solib.c: Move #include "param.h" to work.
3987 Lowercase all the Uppercase Letters In the Messages.
3988 (find_solib): Clean up inferior_so_name for debug printouts.
3989 Allow no argument, to mean all shared libraries.
3991 * symmisc.c: include param.h to get CLEAR_SOLIB.
3993 Wed Sep 5 18:00:08 1990 John Gilmore (gnu at cygint)
3995 * Merge in Kingdon's changes from FSF: the diffs from 3.90.9

4004 Tue Jun 12 16:15:26 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
4008 * Makefile.dist (gdb.tar.Z): Change linking of config so it works.
4010 Thu Jun 7 16:22:27 EDT 1990 Jay Fenlason (hack@ai.mit.edu)

4014 Mon Jun 4 18:12:31 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
4016 * m-sparc.h (REG_STRUCT_HAS_ADDR, STRUCT_ARG_SYM_GARBAGE):
4017 Put parens around gcc_p in expansion.
4019 Thu May 24 15:44:51 1990 Jim Kingdon (kingdon at mole.ai.mit.edu)
4021 * utils.c (lines_to_list): Return 10 if lines_per_page == 0.
4023 Wed May 23 16:36:04 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
4025 * Changes for Sun shared libraries:
4026 blockframe.c (find_pc_partial_function): If a non-text symbol
4027 is found, set *address = pc - FUNCTION_START_OFFSET.
4028 breakpoint.c (insert_breakpoints) [DISABLE_UNSETTABLE_BREAK]:
4029 Disable breakpoints instead of giving an error.
4030 source.c (select_source_symtab): Initialize cs_pst.
4031 symmisc.c: Call CLEAR_SOLIB if defined.
4032 symtab.h: Make text{low,high} CORE_ADDR not int.
4033 (psymtab): New field addr.
4035 dbxread.c: Move DECLARE_FILE_HEADERS outside functions.
4036 (record_misc_function): Give correct type for N_DATA symbols.
4037 (condense_misc_bunches): do "misc_function_count = j" regardless
4039 Take code which is shared between symbol_file_command and
4040 add_file_command and put it into partial_symbol_file_{open,read}.
4041 Split add_file_command into add_file_command and add_file.
4042 Make psymtab_to_symtab read in the string table if the file
4044 Two new parameters to read_dbx_symtab and start_psymtab.
4045 tm-sunos.h: New file.
4047 Tue May 22 17:43:03 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
4049 * infcmd.c: Change cont_command to continue_command and "cont"
4052 Mon May 21 14:41:41 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
4054 * breakpoint.c (enable_breakpoint): Get value of watchpoint.
4056 * defs.h [sparc]: Use <alloca.h> regardless of __GNUC__.
4058 * values.c (USE_STRUCT_CONVENTION): Check for structures of
4059 size 1,2,4,8 rather than size < 8.
4061 * dbxread.c (dbx_lookup_type): Do f->length *= 2 as many times
4062 as necessary, not just once.
4064 * sparc-opcode.h: Add a bunch of new opcodes which Sun as supports.
4066 Thu May 17 15:04:09 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
4068 * {t,x}m-sun386.h, sun386-xdep.c, {x,t}config/sun386
4070 * tm-news.h: Add CALL_DUMMY_*.
4072 * tm-68k.h: Remove duplicate comment at FRAME_FIND_SAVED_REGS.
4074 * config.gdb: In list_host, list_target, use ${i}, not $i.
4076 Tue May 15 21:27:12 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
4078 * source.c (find_source_lines) [BROKEN_LARGE_ALLOCA]: Use xmalloc.
4080 * sparc-opcode.h: Change all store floating-point state register
4081 instructions to have the right match & lose fields.
4083 Sat May 5 12:39:18 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
4085 * Makefile.dist: Move -I${srcdir} to GLOBAL_CFLAGS and pass
4087 config.gdb: If srcdir != ., create readline directory and
4088 copy a makefile into it.
4090 * wait.h, infrun.c: Change WRETCODE to WEXITSTATUS for
4091 consistency with POSIX.
4093 * breakpoint.c (bpstat_stop_status): Disable watchpoint
4094 when we exit its exp_valid_block.
4096 Tue Sep 4 11:46:46 1990 John Gilmore (gnu at cygint)
4098 * Makefile.dist: Bump version to 3.91.3.
4100 * Clean up handling of breakpoint commands (somewhat).
4101 Prompted by Tiemann bug report "cont 10" doesn't work any more.
4103 inferior.h: Add breakpoint_proceeded to inferior status struct
4104 and globals; save it and restore it.
4105 (clear_breakpoint_commands): Cleanup, remove old #define.
4107 infrun.c (clear_proceed_status): Set breakpoint_proceeded.
4108 (save_inferior_status, restore_inferior_status): handle it also.
4109 (proceed): Remove earlier code that set breakpoint_proceeded.
4110 It is now set only in clear_proceed_status.
4111 (clear_proceed_status): Cleanup, use bpstat_clear rather
4112 than clear_breakpoint_commands. No callers need the stop_bpstat
4113 between clear_proceed_status and proceed.
4115 infcmd.c: Add breakpoint_proceeded definition and comment.
4116 (cont_command, jump_command, signal_command): Move call to
4117 clear_proceed_status right next to call to proceed.
4119 breakpoint.c (bpstat_do_actions): Avoid clobbering our
4120 caller's argument while running down the chain of breakpoints.
4121 Use new variable "breakpoint_proceeded" to determine when
4122 a command that it executes moves the inferior past the
4124 (bpstat_clear): Handle NULL argument.
4125 (bpstat_clear_actions): Avoid useless call to
4126 breakpoint_auto_delete.
4127 (delete_breakpoint): Clean up bpstat's that are pointing to
4128 the deleted breakpoint from the stop_bpstat chain.
4129 (breakpoint_auto_delete): Simplify.
4131 * Clean up handling of EOF, error on stdin, etc. This was
4132 prompted by a network problem that caused gdb to go into an
4133 infinite loop filling up its malloc'd memory.
4135 main.c (return_to_top_level): Cleanup: call bpstat_clear_actions,
4136 not clear_breakpoints_commands, which is now gone.
4137 (main): If command_loop returns (e.g. from EOF on stdin), do
4138 a quit_command (looping back to command_loop if quit_command
4139 doesn't really quit).
4140 (command_loop): check result from command_line_input and
4141 exit if it returns NULL, rather than passing the NULL to
4143 (gdb_readline): Free malloc'd result space before returning
4146 * utils.c (query): Handle C-d to mean "yes", just as if the
4147 input was not a terminal. Also avoid infinite loop if EOF
4148 occurs in mid-input-line before newline. This allows
4149 query to be used at EOF on stdin with reasonable results.
4151 * infrun.c (proceed): Set breakpoint_proceeded.
4153 * values.c (value_as_long): Avoid infinite recursion for enums.
4154 (_initialize_values): Fix typo in help msg (kingdon).
4156 * Makefile.dist (RL_LIB): Use RL_LIB_DEP for dependencies,
4157 RL_LIB for linking. This allows -lreadline for linking
4158 and nothing for dependencies, once readline is a real library.
4160 * config.gdb: Jim Kingdon: give useful error message if the
4161 host or target type is not recognized.
4163 * defs.h (alloca): SPARC <alloca.h> does not declare alloca,
4164 it just defines it. Dumb, but deal with it.
4166 * Jim Kingdon suggests:
4167 in xconfig/sun3os4, CFLAGS should be XM_CFLAGS.
4169 Wed Aug 29 18:03:27 1990 John Gilmore (gnu at cygint)
4171 * Makefile.dist (VERSION): Bump version # to 3.91.2.
4173 * Clean up Bothner's changes.
4175 * blockframe.c (clear_pc_function_cache): New function.
4176 * blockframe.c: remake cache_pc_function_* static.
4177 * dbxread.c (symbol_file_command): remove references to
4178 cache_pc_function_* variables.
4179 * dbxread.c (read_struct_type): Use VOFFSET_STATIC.
4180 * printcmd.c: Avoid kludging a global variable (addressprint)
4181 to avoid printing the address of a string twice. Instead,
4182 pass the format letter 's' down low enough that it can be seen
4183 to avoid this problem.
4184 (print_formatted): Pass format arg to value_print.
4185 (restore_addressprint): Remove function.
4186 (do_examine): Avoid hacking addressprint, cleanups and such.
4187 (print_frame_args): Add a comment to a Bothner change.
4188 * symtab.h: define VOFFSET_STATIC and use it instead of "-1".
4189 * symmisc.c (free_all_symtabs): Call clear_pc_function_cache
4190 to wipe out the values cached in blockframe.c.
4191 * symtab.c (find_method): Add comment saying how big you must
4192 allocate to be "big enough". Per being terse again.
4193 * valprint.c (val_print): Handle format letter "s" to print
4194 strings without addresses. Add comment to vtbl printing code
4195 which casts with wild abandon. Rearrange reference-printing
4197 @0xaddr: value (print w/addressprint)
4198 value (print w/~addressprint)
4199 @0xaddr (parameter lists w/addressprint)
4200 or nothing (parameter lists w/o addressprint)
4202 Tue Aug 28 10:47:18 1990 John Gilmore (gnu at cygint)
4204 * Merge more changes from Per Bothner:
4206 Gdb's handling of TYPE_CODE_REF was so counter-C++ (and otherwise
4207 annoying) that I tried to improve it. Here are my suggestions.
4209 These patches all attempt to handle TYPE_CODE_REF (as in C++) better.
4212 Do automatic de-reference when taking the address of a reference.
4214 Don't deref_ref when printing parameter lists.
4216 More attempts at treating refernences properly.
4218 In val_print, if deref_ref==0, don't print dangling " = ".
4220 Add COERCE_REF macro, which de-references an REF.
4222 * Merge changes from Per Bothner:
4224 * Fixed (Sony news)-specific configuration problems.
4225 * Fixed other problems with using vanilla pcc and libc (enum problems;
4226 assumption that vsprintf exists).
4227 * Some major speed-ups (finc_pc_partial_function now caches a match;
4228 parsing avoids duplicate symbol_lookup calls).
4229 * Changed handling of baseclasses (no longer use baseclasses field
4230 of struct type, use the first n_baseclasses fields instead).
4231 * Various minor changes/fixes, most C++-related.
4234 Cache the most previous match from find_pc_partial_function.
4235 (Save both low and high ends of matching function's pc range.)
4236 This speeds up the loop of infrun.c:wait_for_inferior quite
4237 a bit, and makes step/next commands much zippier.
4239 Added an enum->int cast (otherwise, some compilers barf).
4241 No longer set baseclass offset to 0, since multiple
4242 inheritance now mostly works.
4243 Added a number of casts, to shut up compiler warnings
4244 (after stabs where made enums, not ints).
4245 When discarding a symbol table (in symbol_file_command),
4246 must clear the cache introduced in blockframe.c.
4247 Don't convert $vtbl_ptr_type to vtbl any more.
4248 Get rid of TYPE_BASECLASEES and baseclass_vec (see also symtab.h).
4249 Mask off sign bit emitted by g++ for virtual table offset.
4250 Set voffset to -1 (not 1) for static member functions.
4252 Changed parsing/lexing of names to avoid doing symbol lookup twice
4253 (once when lexing to determine symbol class, once for real).
4254 Now only call symbol_lookup once. Fields of 'this' win especially big.
4256 Subpress printing addr twice in the case of 'x/s addr'.
4258 lookup_basetype_type is no longer used.
4259 Add find_methods as recursive helper function to decode_line_1.
4260 This allows multiple inheritance to work.
4261 Also, once one or more matches has been found, do not look in
4262 base-classes. (Baseclass methods would be overridden, anyway.)
4264 Removed baseclasses array in struct type.
4265 Instead of using baseclasses[i], use fields[i-1].
4266 Added virtual_field_bits[i] to indicate if the i'th baseclass is virtual.
4267 Changed sign convention of voffset (previous was inconsistent).
4269 Some macros (CALL_DUMMY and relatives) were missing. Put them back.
4271 Used to assume existence of vsprintf. Re-written to not need it
4272 if HAVE_VPRINTF is undefined.
4274 typecmp was too pessimistic. Made it less so.
4276 Don't print space after address.
4277 If vtable points to a misc symbol (with 0 offset), print it,
4278 since that indicates the actual class of the object.
4279 Changed ype_print_derivation_info to use new inheritance
4280 scheme (without baseclasses vector).
4282 In value_primitive_field, fixed some bugs left over from previous set of fixes.
4283 Also, changes needed because TYPE_BASECLASSES were removed.
4285 REGISTER_U_ADDR didn't work for PC. Rewrote to use an array.
4287 Tue Aug 21 20:08:54 1990 John Gilmore (gnu at cygint)
4290 If there is no path set, and the symbols don't indicate what directory
4291 a file was compiled in, look in the current directory. But either
4292 a path or a known compilation directory will prevent this.
4295 Three independent bug fixes:
4296 * Remove the #if 0 block that breaks some stuff.
4297 * SunOS 4.1 fixed the promoted-parameter-wrong-addr bug in Sun C;
4298 adapt gdb to either SunOS 4.0.* or 4.1.
4299 * MAX_OF_TYPE and MIN_OF_TYPE thinko. By tedg@sun, I think.
4302 Instantiate the class T when looking for methods in it. (Tiemann@sun)
4305 (type_print) Demangle the name being printed.
4306 (type_print_base) Handle botched demangling without coredump (tiemann).
4309 (check_stub_method): Document routine.
4310 (tiemann) fix bug for no-arg functions
4311 Avoid clobbering beyond end of malloc'd storage.
4312 Terminate the argument list properly.
4314 Sat Aug 18 01:29:59 1990 Per Bothner (bothner@cs.wisc.edu)
4316 * Changes merged by John Gilmore:
4319 In breakpoint_1, use new print_address_symbolic instead
4320 of find_pc_partial_function. (This forces use of assembler-level
4321 addresses, and avoids misleading non-mangled source-level names.)
4323 Generalize ansi argument such that -1 means skip arglist totally.
4324 Removed global variable print_ansi_qualifiers (which made
4325 code non-reentrant), in favor of extra explicit arguments
4326 to internal routines.
4328 Add new helper function print_address_symbolic.
4329 Use find_pc_misc_function instead of find_pc_partial_function
4330 (since we want assembler-level symbols here).
4332 Print unknown function as just "f (...)", not "f (...) (...)".
4333 Use new fputs_demangled explicitly.
4335 Fixed a typing violation (problem: value.h cannot be imported
4336 without renaming many variable in this file).
4337 lookup_symbol: If no matching misc_func, look for a C++-mangled name.
4338 decode_line_1: Moved forward some never-reached code.
4339 Made decode_line_2 skip function prologues correctly.
4341 fputs_filtered should not demangle by default.
4342 Add new fputs_demangled to demangle on demand..
4344 Change value_struct_elt to use value_primitive_field (using recursive
4345 utility function search_struct_field). This allows foo.bar to work
4346 for multiple inheritance (so far only for data fields).
4347 Change check_field in the same way (recursive helper function
4348 to support multiple inheritance).
4349 (Note: there are more of these problems that I haven't fixed.
4350 Any code that says TYPE_BASECLASS (t, 1) is probably wrong.)
4351 value_of_this: 'this' symbol name is now just "this", note "$this".
4353 Don't print static members.
4354 Avoid printing "members of <type>" if there are none.
4355 Simplified type_print_derivation_info by merging duplicate code.
4356 Remove useless blank lines in type_print_base (ptype command).
4358 Added declaration of new routine value_primitive_field.
4360 Added value_primitive_field which is generalized version of
4361 value_field that can handle multiple inheritance (non-zero offsets etc).
4362 Re-implemented value_field to call value_primitive_field.
4364 Fri Aug 17 23:33:44 1990 John Gilmore (gnu at cygint)
4366 * infcmd.c -- insert else to avoid 'delete env' coredump when you
4367 delete the whole environment. Karl Berry reported the bug.
4368 * source.c - fix openp to avoid //'s in filenames, which
4369 trigger an Emacs bug causing it to not be able to find files
4370 when running gdb in a window.
4371 * dbxread.c - zap the #if 0 that botches the add-file code.
4372 It seems to work a lot better without all the code commented out.
4374 Fri Jul 20 16:58:46 1990 John Gilmore (gnu at cygnus.com)
4376 * Merge Tiemann's and Ted Goldstein's changes, detailed below,
4379 Tue Jul 17 19:34:33 1990 Ted Goldstein (tedg at golem)
4381 * Makefile - added a ${CFLAGS} to a couple of entries,
4382 added remote-sa.sparc.c
4383 * added remote.sa-sparc.c, a modification of remote.c
4384 which conducts a dialog directly with the SparcStation prom.
4385 * breakpoint.c, infrun.c, sparcdep.c added
4386 remote_insert_breakpoint(), and remote_remove_breakpoint()
4387 to breakpoint.c instead of directly writing breakpoint instructions.
4388 * sparcdep.c on remote_debugging,there is no need
4389 to remove signle step breakpoint instructions.
4390 * main.c added "-epoch" flag and "int epoch_interface" to main.c
4392 * printcmd.c - epoch interface sends lisp expressions to open up
4393 epoch windows on inspection.
4394 * valprint.c - added arrayprint, and addressprint and made adding
4395 format controls easier
4396 * wait.h added a couple of undef's because we were getting
4397 complaints about WSTOPSIG and WTERMSIG begin redefined.
4400 Wed Jul 4 05:27:51 1990 Michael Tiemann (tiemann at masham)
4402 * symtab.c (decode_line_1): Add support for handling method stubs
4403 in the type information.
4405 Tue Jul 3 09:39:18 1990 Michael Tiemann (tiemann at masham)
4407 * values.c (baseclass_addr): Run loop from INDEX+1 to
4408 N_BASECLASSES; otherwise, we can still get into a loop.
4409 @@ This should be restructured to use a cleaner search strategy.
4411 Sun Jul 1 12:28:51 1990 Michael Tiemann (tiemann at masham)
4413 * dbxread.c (define_symbol,read_type): Grok GNU C++'s new
4414 abbreviation "Tt" for tags which have the same name as their
4417 Fri Jun 29 01:03:46 1990 Michael Tiemann (tiemann at masham)
4419 * symtab.c (list_symbols): add ability to set breakpoints on all
4420 the functions which match a particular regular expression.
4422 Tue Jun 26 04:26:29 1990 Michael Tiemann (tiemann at masham)
4424 * cplus-dem.c (cplus_demangle): New parameter ANSI says whether we
4425 should print ANSI qualifiers (such as `const' and `volatile').
4426 All callers changed to call with ANSI == 1, except from
4427 `check_method_stub', which uses old-style syntax.
4429 * symseg.h (struct fn_field): Remove unneccessary `args' field.
4430 * symtab.h (TYPE_FN_FIELD_ARGS): Redefined.
4432 * values.c (check_stub_method): New function.
4434 * cplus-dem.c (do_type): Handle "long long" (encoded as 'x').
4436 * dbxread.c (read_type): Handle new GNU C++ method type stubs.
4437 * valprint (type_print_base): Ditto.
4439 * symtab.c (gdb_mangle_typename): New function.
4441 Tue Jun 5 00:18:43 1990 Michael Tiemann (tiemann at gzilla)
4443 * breakpoint.c (catch_command): New function. Provides a
4444 mechanism to set breakpoints based on catch clauses.
4445 (disable_catch): Similar, but disables breakpoints on catch
4447 (delete_catch): Similar, but deleted breakpoints on catch clauses.
4449 Sun Jun 3 22:54:08 1990 Michael Tiemann (tiemann at gzilla)
4451 * blockframe.c (blockvector_for_pc): New function.
4452 * blockframe.c (block_for_pc): Changed to call
4453 `blockvector_for_pc' and get the block itself.
4455 * stack.c (catch_info): New function. Prints info about
4456 exceptions which can be caught in the current frame.
4457 * stack.c (print_frame_label_vars): New function. Similar to
4458 `print_frame_local_vars'.
4459 * stack.c (print_block_frame_labels): Prints out labels that are
4460 defined in this frame. These labels are exceptions that can be
4463 * dbxread.c: Updated to handle N_CATCH symtab types.
4465 Thu May 3 22:10:00 1990 Michael Tiemann (tiemann at teacake)
4467 * valprint.c (everywhere): TYPE_NAME (TYPE) no longer comes in the
4468 form "struct ..." for GNU C++. Don't flush any part of TYPE_NAME
4469 when printing the type.
4471 Wed May 2 22:43:04 1990 Michael Tiemann (tiemann at teacake)
4473 * valprint.c (val_print): Use `baseclass_addr' to access the
4474 baseclasses pointed to via the derived class object at VALADDR.
4476 * values.c (baseclass_addr): New function. Casts derived pointers
4477 to baseclass pointers taking virtual baseclasses and multiple
4478 inheritance into account.
4480 Sat May 5 12:39:18 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
4484 Fri May 4 12:12:55 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
4486 * breakpoint.c (watch_command, bpstat_stop_status): Deal with
4487 exp_valid_block field correctly.
4489 * infrun.c (wait_for_inferior): When checking "don't even think
4490 about breakpoints" if stop_signal == SIGTRAP && trap_expected,
4491 also check step_resume_breakpoint.
4492 Insert breakpoints and continue (not step) if
4493 step_resume_break_address != NULL, even if another_trap.
4494 If trap_expected and we enter sigtramp, then set up a
4496 If trap_expected is set when we hit the step_resume_break,
4498 When calling resume and trap_expected says tell resume to step
4499 (2 places), also check step_resume_break_address.
