1 Thu Aug 22 22:17:06 1991 Stu Grossman (grossman at cygint.cygnus.com)
3 * coffread.c, symfile.c, stack.c: saberized.
5 Thu Aug 22 16:20:27 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
7 * doc/refcard.tex: permuted Essential Commands sec
9 * doc/gdb.texinfo: new C++ chapter; revised installation appendix;
11 set/show symbol-reloading
12 default set complaints 0
14 RET-repeat disabled after prompted long displays
15 processID (attach) interpretation of 2nd GDB cmdline arg
17 Thu Aug 22 14:05:47 1991 Stu Grossman (grossman at cygint.cygnus.com)
19 * expread.y, coffread.c, dbxread.c, target.c, mem-break.c,
20 cplus-dem.c, values.c, valprint.c, symfile.c, remote.c,
21 breakpoint.c, main.c: lint.
23 Thu Aug 22 02:02:26 1991 John Gilmore (gnu at cygint.cygnus.com)
25 Install new configuration scheme for GDB and friends.
27 * config.sub: Translate ordinary names to three-part names.
28 * configure: Use three-part names internally.
29 * configure.in: Translate three-part names to filenames.
31 * README, WHATS.NEW: Update for gdb-4.0.
32 * Makefile.in: Roll VERSION to 3.99.
34 Wed Aug 21 18:21:09 1991 John Gilmore (gnu at cygint.cygnus.com)
36 * infptrace.c (KERNEL_U_ADDR_BSD): Include a.out.gnu.h.
37 * i960-tdep.c, m68k-tdep.c, sparc-tdep.c, tm-i960.h,
38 tm-m68k.h, remote-nindy.c: Change ext_format_XXX structs
39 to single structures rather than arrays; when passing
40 their address, use &. This avoids trouble with bdead compilers.
41 * mcheck.c: Don't include <stdlib.h>; just declare "void abort();"
42 instead. This avoids portability headaches.
43 * mips-tdep.c (mips_do_registers_info): Only print FP regs if
45 * source.c (open_source_file): Avoid ANSI const bdeath by
46 skipping declaration and then casting result value.
47 * tm-hp300bsd.h: Clarify comment.
48 * utils.c (strstr): Result is const char *; ANSI bdeath.
49 * xm-hp300bsd.h: Define HOST_BYTE_ORDER. Redefine INT_MIN,
50 since system include file defines it differently from "defs.h",
51 though the two are equivalent for our purposes.
52 * tconfig/hp300bsd: Add m68k-tdep.o.
54 Tue Aug 20 16:01:11 1991 John Gilmore (gnu at cygint.cygnus.com)
56 * tconfig/sun*4: Remove warnings about system assembler.
58 Mon Aug 19 13:44:46 1991 John Gilmore (gnu at cygint.cygnus.com)
60 * mcheck.c: Avoid warning about undeclared abort fn.
61 * tm-sparc.h (PC_ADJUST): Avoid calling error() from this;
62 it causes recursive calls to error() when used in cleanups.
63 To do so requires that we make it a function, so we do.
64 * sparc-tdep.c (sparc_pc_adjust): New implem of PC_ADJUST.
65 * utils.c (do_cleanups): Remove the current cleanup from the
66 chain *before* calling it, in case error() is called from it.
67 The result won't be pretty, but won't be an infinite loop either.
69 Mon Aug 19 00:41:04 1991 Michael Tiemann (tiemann at cygint.cygnus.com)
71 * dbxread.c (read_struct_type): Grok anon structs for C++.
72 (vb_name, vptr_name): Null terminate these strings.
74 Fri Aug 16 08:31:03 1991 John Gilmore (gnu at cygint.cygnus.com)
76 Minor bug fixes from BSD Net2 gdb:
78 * blockframe.c (get_prev_frame_info): If FRAME_CHAIN_COMBINE
79 returns 0, there is no previous frame.
80 * breakpoint.c (commands_command): If !from_tty, don't call
81 input_from_terminal_p().
82 * dbxread.c (record_misc_function): Speed up slightly.
83 (compare_psymbols): Ditto.
84 * infcmd.c (do_registers_info): Take a second argument to
85 determine whether to print float registers. "info registers"
86 does not do so anymore. "info all-registers" does, now.
87 * mips-tdep.c, pyr-tdep.c (xxx_do_registers_info): Take second
89 * tm-mips.h, tm-pyr.h (DO_REGISTERS_INFO): Pass second arg.
90 * inflow.c (initialize_inflow): Set tflags_ours correctly.
94 * breakpoint.c (bpstat_do_actions): Use a cleanup to restore
95 executing_breakpoint_commands if we are interrupted by error.
96 * coffread.c (init_lineno): Avoid problem with zero-sized linetab
97 versus malloc/free. From: john@labtam.labtam.oz.au (John Carey).
98 * core.c (solib_add_stub, core_open): Call SOLIB_ADD inside a
99 catch_errors() so we can setup the frame regardless of whether
100 the shared libs work.
101 * ieee-float.c (double_to_ieee_extended): Get exponent from
102 right place in little-endian systems. From John Carey.
104 Thu Aug 15 18:43:57 1991 John Gilmore (gnu at cygint.cygnus.com)
106 * main.c: Remove unused terminating_signals and catch_termination().
107 (long_options): Terminate with a zero element.
108 [Bugfix from Atsuo Kawaguchi <atsuo@hark86.harl.hitachi.co.jp>.]
109 (gdb_readline): Make call-compatible with readline.
110 (init_signals): Improve comments re vfork vs. signal.
112 * utils.c (prompt_for_continue): Use new gdb_readline().
113 If we prompt for continuation, we don't let CR repeat the previous
114 command, once we get back to a prompt. It's too easy to keep
115 hitting CR, expecting "--more--" prompts, and have some long
116 command start repeating on you.
118 Tue Aug 13 16:17:56 1991 John Gilmore (gnu at cygint.cygnus.com)
120 * blockframe.c (frameless_look_for_prologue): Speed up by
121 calling SKIP_PROLOGUE_FRAMELESS_P if it's defined.
122 * tm-sparc.h (SKIP_PROLOGUE, SKIP_PROLOGUE_FRAMELESS_P):
123 Define two variants, one faster.
124 * sparc-tdep.c (sparc_frame_chain): Use target_read_memory
125 and return zero, rather than giving an error.
126 (setup_arbitrary_frame): Initialize the PC in the new frame.
127 (skip_prologue): Add a second arg saying whether we're just
128 checking for a frameless function or not.
130 * core.c (core_open, core_close, core_xfer_memory): Move
131 section table pointers and bfd* into the target_ops.
132 (core_open): Allow errors in shared lib reading, etc.
133 (core_files_info): Describe shared library sections.
135 * exec.c (exec_open, exec_close, exec_xfer_memory, xfer_memory,
136 exec_files_info, set_section_command): Move section table
137 pointers and bfd* into the target_ops.
138 (add_to_section_table): Add BFD to section table.
140 * target.c (target_xfer_memory, target_info): Pass target to
141 xfer_memory and target_info functions.
144 * gdbcore.h: Move struct section_table.
145 * target.h: New home of struct section_table.
147 * solib.c (solib_add): New argument is the target_ops whose
148 section list is to be added to, if any. Reallocate the
149 sections in that target to add any that come from shared libs.
150 (throughout) so_sections renamed to sections.
151 (solib_xfer_memory): Deleted.
152 * tm-sunos.h (SOLIB_ADD): Add target argument.
153 (SOLIB_XFER_MEMORY): Delete.
155 * core.c, exec.c, inftarg.c, remote-eb.c, remote-nindy.c,
156 remote-vx.c, remote.c, target.c, target.h: Remove add_syms vector
157 from target_ops. It's the same on all targets. Add two section
158 pointers to target_ops.
160 * stack.c (find_relative_frame): Dump ancient algorithm for
161 "down", just use handy "next" pointers.
162 (frame_command): Don't error if there is no stack; let user
165 * inflow.c (new_tty_prefork, new_tty): New prefork routine
166 modifies static state in the parent process; new_tty itself
167 runs in the child and modifies the child's file descriptors
168 to match the saved static state.
169 * infrun.c (child_create_inferior): Call new_tty_prefork,
172 * infptrace.c (child_xfer_memory): Add ignored target arg.
173 * remote-eb.c (eb_xfer_inferior_memory): ''
174 * remote-nindy.c (nindy_xfer_inferior_memory): ''
175 * remote-vx.c (vx_xfer_memory): ''
176 * remote.c (remote_xfer_memory): ''. Rename from
177 remote_xfer_inferior_memory.
179 * main.c (main): Only try to attach "corefile" argument if
180 it starts with a digit.
182 * symfile.c (symbol_reloading): New "set/show" variable.
183 (symbol_file_add): Shorten message about symbol reading.
184 (add_symbol_file_command): Merge with add_syms_addr_command,
185 since this should work on all targets now.
186 (stop_whining): Default to zero, to shut up complaints
187 about bad symbol tables on many systems.
188 (free_named_symtabs): Just exit unless symbol_reloading.
190 * xm-sun3os4.h, xm-sun4os4.h: Define BROKEN_LARGE_ALLOCA,
191 and add comment explaining shared library screw.
193 * source.c: #if defined => #ifdef.
195 Thu Aug 8 12:23:19 1991 John Gilmore (gnu at cygint.cygnus.com)
197 * doc/gdbint.texinfo: Improve doc on porting to new OS's.
199 Tue Aug 6 17:16:15 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
201 * doc/rdl-apps.texinfo: provide default readline-appendix finder
202 (doc/Makefile knows how to make one for local config)
204 * Makefile.in: use doc/Makefile for doc targets
206 * doc/Makefile: GDB documentation now has its own Makefile
207 doc/refcard.tex: renamed from "gdbrc.tex"
208 doc/.Sanitize: add Makefile; recognize renamed refcard.tex
209 doc/gdbint.texinfo: add markup in "Cleanups" chapter
212 Fri Aug 2 00:13:06 1991 John Gilmore (gnu at cygint.cygnus.com)
214 * values.c (baseclass_addr): When reading target memory, use the
215 length of the basetype, not the upper type. We've only malloc'd
216 enough space for the basetype, leading to errors in free().
218 * expprint.c (print_subexp): Print UNOP_MEMVAL of an OP_LONG that
219 ends up as a function specially, since we know the actual type of
220 the pointed-to address. This (somewhat) fixes display of
221 expressions that include misc_function_vector names. Try `cond 1
222 !strcmp("a","b")' then `i b'.
224 * infrun.c: Move DO_DEFERRED_STORES from proceed() to resume().
225 The child can be proceeded from inside wait_for_inferior in
226 evaluating breakpoint conditions, and DO_DEFERRED_STORES was
227 getting skipped in that case.
229 * expprint.c (print_subexp): Use filtered output, since the
230 subroutines we call use it, otherwise the output is horribly
231 mangled, since output of wrappable stuff comes out late.
233 * Makefile.in: Bump VERSION to 3.98.1
235 * infrun.c (child_create_process): Use execlp to find the
236 shell to exec our target program. This requires some fiddling
237 with `environ' since there is no execlpe().
239 Thu Aug 1 15:35:17 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
241 * Makefile.in, doc/gdbrc.tex, doc/rc-* (new files):
242 Minor rearrangement of refcard permits two new make targets--
243 gdbrc.dvi DVI output for refcard, using CM fonts
244 gdbrc.ps PostScript refcard, using PS fonts
246 Wed Jul 31 16:46:21 1991 John Gilmore (gnu at cygint.cygnus.com)
250 * TODO, Projects, WHATS.NEW, README: Update for gdb-3.98.
251 * Makefile.in (gdb-all.texinfo): Avoid touching file if M4 dies.
253 Wed Jul 31 16:35:58 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
255 * doc/gdb.texinfo: last changes for release.
256 Minor typo and formatting fixes; incorporated most fixes remaining from
257 filed mail commenting on earlier drafts.
259 Added warnings: pipes don't work in run command;
260 conditions are converse of assertions;
261 step over fn without debug info goes to next fn;
262 vars may have "wrong" values near fn entrance, exit
264 Added example from Kingston on printing repeated nonadjacent values
266 Added explicit mention that in Emacs gdb mode C-c and C-z are like
267 shell mode for signals
269 Renamed "Stepping and Continuing" to "Continuing and Stepping" so it
270 doesn't sound so much like its parent "Stopping and Continuing"; also
271 moved entries on continue to top of section, so they don't get lost.
273 Improved installation directions in appendix, added manual formatting
276 Tue Jul 30 17:26:39 1991 John Gilmore (gnu at cygint.cygnus.com)
278 * configure.in: Remove xm.h and tm.h even if we aren't linking
279 new ones, so "./configure sun4; ./configure none" does the right
280 thing. Assume that alldeps.mak and depend are already built in
281 srcdir, and avoid running "make" (particularly "make depend",
282 which involves "gcc") from inside configure. Build Makefile
283 directly rather than building Makefile.conf first.
284 * configure: Regenerate with above changes.
285 * Makefile.in: Use $(BISON) to find bison. Roll VERSION
286 to 3.98. Revise gdb.tar.Z procedure to produce a file
287 called gdb-$(VERSION).tar.Z but which unpacks into a
288 directory called "gdb". Move non-source files out of
289 $(SFILES_SUBDIR). Pretty up alldeps.mak with comments.
290 (depend): Don't try to do "gcc expread.y".
291 (expread.o): Update dependencies by hand.
293 Mon Jul 29 15:21:09 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
296 Fixed a variety of small typos that prevented info from formatting
297 cleanly; altered too-long heading for GPL Appendix, as discussed
298 w/RMS; Changed date on cover to July 91.
300 Fri Jul 26 13:20:02 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
303 (1) Applied some fixes due to comments from Larry Breed (easier ones
305 (2) Eliminated use of @footnote---had my doubts about it anyways, and
306 it's broken in latest texinfo
307 (3) Introduced *some* use of [] for optional arguments, where
308 explanation is not simpler by listing cmd w arg and cmd w/out arg
309 separately. Still not using @deffn.
310 (4) Dropped in GPL-2. NOTE: one of GPL-2 or texinfo is broken; a
311 couple of headings are too long. Need patches to texinfo or revision
314 * Partial update to README (which still needs work for this
315 release!): (1) use of configure corrected for new script,
316 (2) "make gdb.dvi" and "make gdb.info" mentioned.
318 Wed Jul 24 06:44:02 1991 John Gilmore (gnu at cygint.cygnus.com)
320 * symtab.c (lookup_symbol): Don't complain right off about
321 no debug symbols; use the misc function vector first.
322 (list_symbols): Use misc function vector to find symbols
323 that don't have debug info, and print them.
324 (find_pc_symtab): Temporarily avoid fatal() when psymtab
325 PC range doesn't match symtab PC range, as it does on the
326 MIPS because our symtab reading isn't perfect.
328 * dbxread.c (dbx_symfile_read): Make warning about
329 "no debug symbols" slightly nicer.
331 * source.c (select_source_symtab): If "main" symbol exists,
332 but decode_line_spec can't find line info, don't just return
333 a zero; try other source symtabs or give an error.
335 * mipsread.c (parse_partial_symbols): Sort the psymtabs by
336 their low addresses first, then rip through fixing high addrs.
338 * ns32k-opcode.h (sfsr): Bugfix from Rune Nerg}rd,
340 (NS32K_SVC_IMMED_OPERANDS): Reverse the #ifndef.
342 Tue Jul 23 18:52:43 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
344 * Minor, mostly mechanical, cleanup of doc subdir for clean
345 makeinfo'ing and TeXing; also ensured gdb-all.texinfo (post-m4)
346 and gdb.info (post- texinfo2 makeinfo) generated for distribution.
348 Sun Jul 21 03:54:52 1991 John Gilmore (gnu at cygint.cygnus.com)
350 Mostly MIPS and general symbol-reading fixups.
352 * doc/gdbint.texinfo: Add documentation on symbol-reading
355 * mipsread.c: Remove kludges around #include "ecoff.h".
356 Remove redefinitions of a_magic, etc, no longer used.
357 (parse_symbol, ): Convert "Internal:" printfs to complain()ts.
358 Fix global overview comments to match symfile.c protocol.
359 (mipscoff_new_init): Eliminate cur_hdr if we have one.
360 (mipscoff_symfile_read): Eliminate unused code. Avoid
361 sorting all the symtabs, when all we have read here is psymtabs.
362 The symtabs are sorted as they are created anyway. Tell
363 condense_misc_bunches whether we're mainline.
364 (psymtab_to_symtab_1): Pass filename when recursing, to make
365 stack trace more informative.
366 (parse_partial_symbols): Assume cur_hdr as argument.
367 (read_mips_symtab): Don't clobber cur_hdr, so it can be freed.
368 Pass cur_hdr implicitly to parse_partial_symbols. Avoid checking
369 the TYPE_NAME of char *, since that's done in symfile.c.
370 (free_numargs, parse_symbol, add_symbol, add_block,
371 shrink_linetable): Declare these fns void.
372 (upgrade_type): Convert tree of if's to switch. Clean up
373 bogus "off == 0" handling with a complaint. Avoid setting
374 field bitpos and bitsize of array with lower and upper bounds.
375 Check specified bitsize of elements against their actual type's
376 bitsize, and complain if different. Complain about unknown
378 (parse_fdr): Don't assume sizeof(char *) == sizeof (struct *).
379 (psymtab_to_symtab_1): Print names of subsidiary files that
380 are being read in. FIXME, we read far too many files. This code
381 is not the problem, the problem is in parse_fdr where the psymtabs
383 (cross_ref): Result should indicate that we used one aux entry
384 normally, or two if we encountered a "next" entry. This used
385 to leave the caller pointing at the wrong aux entry.
386 (add_symbol): If overflowed cur_block, reallocate it larger,
387 chase all pointers to it, and complain(), rather than clobber memory.
388 (shrink_block): Use xrealloc rather than xmalloc-and-copy.
389 (new_field): Only allocate one field initially, not two.
390 Pull ++ out of macro argument. Simplify.
391 (_initialize_mipsread): Avoid initialization of importd
392 global_psymbols and static_psymbols.
394 * symfile.c (psymtab_to_symtab): Depend on XXX_psymtab_to_symtab
395 to properly set pst->symtab; avoid searching for it.
396 (symfile_fns): Improve comments, add a FIXME.
397 * dbxread.c: Update comments to reflect symfile protocol.
398 (read_ofile_symtab, end_symtab): Return the symtab.
399 (psymtab_to_symtab_1): Set pst->symtab.
401 * coffread.c (coff_symfile_read): tell condense_misc_bunches
402 whether we're mainline.
404 * symfile.h (sym_fns): Remove unused sym_discard member.
405 * coffread.c, mipsread.c, dbxread.c: Remove XXX_symfile_discard.
407 * mtrace.c (mtrace): Take effect if mallwatch is set, even if
408 the environment variable is not.
409 * infcmd.c (finish_command): Use filtered printfs.
410 * cplus-dem.c: Add struct tags to a few unnamed structs.
411 * valops.c (value_coerce_array): Improve comments.
412 * valprint.c (type_print_varspec_suffix): Print array size only
413 if greater than zero.
414 * m88k-tdep.c: Shift some lines left by one space, that had
415 apparently been trashed at some point.
416 * TODO: More things to do, a few got done.
418 Thu Jul 18 22:46:05 1991 John Gilmore (gnu at cygint.cygnus.com)
420 * symtab.h (LOC_EXTERNAL): Eliminate in favor of LOC_STATIC.
421 (ldsymoff, ldsymlen, globals_offset, statics_offset): Improve
423 * dbxread.c (read_dbx_symtab): LOC_EXTERNAL -> LOC_STATIC.
424 * expread.y, findvar.c, symmisc.c: Ditto.
425 * printcmd.c (address_info): Update printed forms of LOC_
426 symbols. Elim LOC_EXTERNAL.
427 (print_frame_args): Keep track of param stack offsets before
428 re-looking up to find the local register param is kept in.
430 * mipsread.c: Use <symconst.h> and <sym.h> rather than <syms.h>.
431 Further integration of mipsread into gdb. Eliminate unused
432 routines, duplicate declarations. Handle static symbols in
433 psymtabs as well as external symbols. When reading symtabs,
434 insert symbols into the correct block (global, static, or a local
436 (read_mips_symtab, parse_partial_symbols): Don't pass useless
438 (mipscoff_symfile_read): Don't call select_source_symtab.
439 (parse_symbol): Use SYMBOL_VALUE_ADDRESS where appropriate,
440 rather than SYMBOL_VALUE.
441 (parse_external): Comment clobbering of top_stack.
442 (parse_partial_symbols): Update comments. Allocate and parse
443 static symbols as well as external symbols. FIXME, enum values
444 are not handled in this pass, but should be. Inline new_psymbol.
445 Use SYMBOL_VALUE_ADDRESS.
446 (psymtab_to_symtab_1): Read symbols into global static block
447 by default (until enter some function's local block context).
448 (sort_blocks): Clean up STATIC_BLOCK as well as GLOBAL_BLOCK.
449 (destroy_all_symtabs, new_psymbol): Eliminate, unused.
451 * source.c (select_source_symtab): Select a source symtab
452 from either the symtabs or, failing that, the psymtabs.
453 (list_command): Update error message.
454 (forward_search_command, reverse_search_command): Use getc, not
455 fgetc, for speed. FIXME, add comment about buffers that die if
456 overrun by long line.
458 * values.c (unpack_field_as_long, modify_field): Avoid shifting
459 by an entire word, which is not portable, if we have a 32-bit
460 field. (Code in dbxread.c already turns such bitfields, if
461 aligned, into ordinary ints, but fixing this will help for other
462 symbol formats and for future changes.)
463 * core.c (core_open): Handle ANSI const brain death.
464 * utils.c (vprintf): Fix varargs typo.
466 Sun Jul 14 00:42:53 1991 John Gilmore (gnu at cygint.cygnus.com)
468 * findvar.c (find_var_value): Handle &function better.
469 * TODO: Document work needed on &fn and &array.
470 * printcmd.c (print_address_symbolic): New arg is the prefix
471 to print if a name is printed.
472 (print_address_demangle): Honor "set print address" now.
473 Use new arg above to improve spacing of output.
474 * valprint.c (val_print): When printing function pointers,
475 print symbolic form too.
476 * breakpoint.c (breakpoint_1): Use new print_address_symbolic.
478 Mon Jul 8 19:02:46 1991 John Gilmore (gnu at cygint.cygnus.com)
480 * core.c (memory_error): Reword error msg to mislead less.
482 * mips-pinsn.c (print_insn_arg 'd'): Print $ with reg name.
484 * mipsread.c (read_mips_symtab, read_the_mips_symtab,
485 parse_partial_symbols): Use newer BFD internals (external_filehdr
486 and external_aouthdr), byte-swap the fields that we care about
487 before using them, and make the file header data local to
488 read_the_mips_symtab rather than global.
490 Sat Jul 6 01:34:15 1991 John Gilmore (gnu at cygint.cygnus.com)
492 * ns32k-opcode.h (movmw, movmd): Fix opcodes. Bug fix
493 from Rune Nerg}rd <runene@ifi.uio.no> on 5 Jul 1991.
495 * main.c (command_line_input): Flush stdout and stderr
496 before every call to readline. This reportedly fixes a bug
497 that comes up in Sys V running emacs-gdb and/or xxgdb,
498 when stdin/out are pipes or sockets.
500 Thu Jul 4 14:47:06 1991 John Gilmore (gnu at cygint.cygnus.com)
502 * configure.in, Makefile.in: Avoid rebuilding "depend" as much.
503 Avoid declaring Makefile dependencies, because GNU Make stupidly
504 tries to update it if we do.
506 * coffread.c: Revise for minor changes to bfd internal coff
509 * configure: If -template= is given a relative path, make it
510 absolute before recurring in subdirectories.
512 * configure, configure.in, Makefile.in: Install "configure" script
513 as replacement for config.gdb.
514 * config.gdb, Makefile.dist, Makefile.sdir: Remove
515 * README: Update for configure, mostly. FIXME.
517 * Add dec3100 as equivalent to littlemips. Indicate in all host &
518 target config files that they are for the host. When the lines
519 get copied into the Makefile, this makes it more obvious what's
522 Mon Jun 24 23:49:07 1991 John Gilmore (gnu at cygint.cygnus.com)
524 * sparc-opcode.h (trap opcodes): Avoid leading spaces or
525 tabs, which end up in the disassembler output inadvertently.
527 Wed May 29 23:01:03 1991 John Gilmore (gnu at cygint.cygnus.com)
529 Make it compile cleanly in an ANSI GCC2 environment.
531 * blockframe.c: <stdio.h>
532 * cplus-dem.c: free takes a void *, ifdef __STDC__
533 * dbxread.c (read_huge_number): avoid gcc2 bug hoisting calc of
535 * defs.h (alloca): Avoid doing anything if alloca already def'd.
536 * stddef.h, stdlib.h: Remove these files.
537 * symtab.c: Avoid declaring qsort, close.
538 * symfile.c: Avoid declaring close.
539 * utils.c (vprintf): Declare "ap" arg as proper va_alist.
540 * sparc-tdep.c: Avoid including lots of Sun-host-specific files.
542 Assorted other changes.
543 * dbxread.c: include "libaout.h", not "liba.out.h".
544 * printcmd.c (print_frame_args): Set recurse properly for
545 indentation of struct and array parameters.
546 * valops.c (value_cast): Allow cast to void.
547 * infrun.c (resume): If NO_SINGLE_STEP, call machine dependent
548 single_step() in a target-independent fashion.
549 * sparc-tdep.c (single_step): Don't call ptrace ourselves, just
550 set up to be ready to continue. This makes us target independent.
551 * infptrace.c (child_resume): Remove call to single_step; now
552 can single step a SPARC target of any kind.
554 Wed May 22 18:18:24 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
556 * Makefile.dist, doc/gdb.texinfo, doc/*-m4.texinfo: split up GDB
557 docn into separate sections---basically chapters, plus two loose
558 pieces that can be configured to go in different places. This
559 allows GNU m4 to preprocess the manual without coredumping.
561 * Makefile.dist: tell TeX where to find texinfo.
563 Mon May 20 12:15:04 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
565 * Makefile.dist, doc/gdb.texinfo: respectively create, and use,
566 the new target "rdl-apps.texinfo" which captures the Makefile
567 variable that records where to find the Readline libraries.
569 Sun May 19 05:36:59 1991 John Gilmore (gnu at cygint.cygnus.com)
571 * tahoe-pinsn.c: #include "tahoe-opcode.h", not "opcode.h".

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

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

1265 been read in, particularly for VxWorks.
1267 * dbxread.c (read_dbx_symtab): Allow N_SOL to cleanly take us back
1268 to the main file, as well as to include files. Also, put global
1269 functions into the global psymtab, to make "i fun" work.
1270 (end_psymtab): Free named symtabs and psymtabs for a file, once a
1271 new psymtab for it has been read.
1272 * coffread.c (end_psymtab): Free named symtabs and psymtabs for
1273 a file, once a new symtab has been read for it.
1274 * mipsread.c: FIXME. We need to do the same for MIPS, but it
1275 looks harder to determine the top-level block before it's been
1276 queued to the psymtab list.
1278 * symfile.c (symbol_file_add): Use filtered printing and wrap it.
1279 If we have wiped out any old symbol tables, clean up at end of
1281 (symbol_file_command): Don't reference symfile_fns if it's zero.
1283 * symtab.h (GLOBAL_BLOCK, STATIC_BLOCK, FIRST_LOCAL_BLOCK): New
1284 defines for the blocks of a blockvector that contain global and
1285 file-static symbols and the first of the smaller scope contours.
1286 * symtab.c (lookup_symbol, find_pc_symtab, find_pc_line,
1287 decode_line_1, make_symbol_completion_list): Use the above.
1288 * coffread.c (end_symtab, patch_opaque_types): Ditto.

1294 * symtab.c (list_symbols): Process the first symbol of the
1295 static psymbols list.
1296 (types_info): Restore this function from its untimely #if 0.
1297 It's not perfect, but it is better than nothing.
1298 (_initialize_symtab): Restore "info types".
1300 Thu Apr 11 05:23:19 1991 John Gilmore (gnu at cygint.cygnus.com)
1302 * m68k-stub.c: Remote stub for 680x0's, created from
1303 rem-m68k.shar (which is removed).
1304 * nindy-share/{Makefile,Onindy.c,blout.h,env.h,nindy.c,ttyflush.c}:
1305 Remove RCS log stuff now that we use CVS and it blows our diffs.
1307 Wed Apr 10 14:18:06 1991 John Gilmore (gnu at cygint.cygnus.com)
1309 * symmisc.c (free_named_symtab): Make it work, in its current
1310 kludgy fashion. Change result to indicate if we blew away bkpts.
1311 * dbxread.c (end_symtab): Accumulate result from
1312 free_named_symtab and print warning if we blew user's state.
1313 * symfile.h: free_named_symtab now returns an int.
1315 Mon Apr 8 23:57:43 1991 John Gilmore (gnu at cygint.cygnus.com)
1317 * dbxread.c (dbx_symfile_read): Initialize psymbol list if this
1318 is the first symbol read, even if not mainline.
1319 (dbx_psymtab_to_symtab): symfile might be zero, cope.
1320 * exec.c (exec_ops): Add_syms_addr is valid in our tvec.
1321 (set_section_command): New command ("section xxx yyy" -- should
1322 be renamed to "set section xxx yyy" FIXME) which sets the
1323 base address of a section of the exec file, overriding the
1324 virtual address that BFD reports.
1326 Fri Apr 5 17:14:39 1991 John Gilmore (gnu at cygint.cygnus.com)
1328 * exec.c: Add add_syms_addr_command to exec_ops, so you can
1329 load symbols at any address while examining an exec file.
1331 Thu Apr 4 10:09:35 1991 John Gilmore (gnu at cygint.cygnus.com)
1333 * tm-i386v.h (FLOAT_INFO): Don't define it, since the code
1334 for printing the float info is host-dependent, not
1335 target-dependent. FIXME.
1336 * i386-pinsn.c: Move #includes to top, remove useless ones.
1337 * i386-tdep.c: Don't bother including <.../reg.h> since we
1338 don't use it (and it doesn't exist on host systems).
1340 * ieee-float.c (ieee_extended_to_double): Convert NaN to Inf.
1341 Convert negative numbers properly.
1342 (ieee_test): Make numbers really random; fix format arg.
1344 * infcmd.c (attach_command, detach_command): Don't repeat on CR.
1345 * core.c (core_detach): Unpush core_ops, which might not be on
1346 top. We used to just pop the top, which broke things. Don't
1347 need dont_repeat() any more.
1348 (core_file_command): Psst! Don't repeat it.
1349 * remote-nindy.c (nindy_detach): Don't need dont_repeat() now.
1350 * expprint.c (print_subexp): Avoid switch fallthru on
1351 BINOP_ASSIGN_MODIFY, so we can print += and such.
1352 * frame.h: Fix typo.
1353 * inflow.c (kill_command): After killing inferior, print our
1354 current frame in the core file, if we have one.
1355 (generic_mourn_inferior): When inferior dies, either select
1356 the current frame (in the new target, e.g. core file), or
1357 set both the current and selected frames to NULL.
1359 Changes from Peter Schauer.
1361 * infptrace.c: Avoid <sys/ptrace.h> on USG.
1363 * Make all file names fit in 14 characters (sigh and damn!):
1364 mv hp300hpux-xdep.c hp300ux-xdep.c
1365 mv symmetry-xdep.c symm-xdep.c
1366 mv symmetry-tdep.c symm-tdep.c
1367 mv convex-opcode.h convx-opcode.h
1368 mv tm-vxworks960.h tm-vx960.h
1369 mv tm-vxworks68.h tm-vx68.h
1370 mv Makefile.srcdir Makefile.sdir
1371 mv gdb-int.texinfo gdbint.texinfo
1372 mv remote-sa.m68k.shar rem-m68k.shar
1373 mv remote-multi.shar rem-multi.shar
1374 * Makefile.dist, README, config.gdb, convex-pinsn.c,
1375 tconfig/symmetry, tconfig/vxworks960, tconfig/vxworks68,
1376 xconfig/hp300hpux, xconfig/symmetry: Change names to shorter
1379 * command.c (user_info_1, user_info): New command for listing
1380 the user-defined commands.
1382 Wed Apr 3 15:00:26 1991 John Gilmore (gnu at cygint.cygnus.com)
1384 * dbxread.c (really_free_pendings): Clear file_symbols
1385 and global_symbols after freeing them; otherwise, running
1386 this function twice (if it appears twice on the cleanup
1387 chain), we try to free things twice.
1389 * dbxread.c (read_dbx_symtab): Calculate end_of_text_addr
1390 based on text_addr (the address of text in core), not on addr (the
1391 offset between text in the .o file and in core). This change
1392 is from Peter Schauer.
1394 * main.c: Define ALL_CLEANUPS as a cast of zero.
1395 (return_to_top_level): Use it.
1396 (main): Do all cleanups after each command run as part
1397 of the gdb startup sequence. Also do all cleanups before
1398 entering the command loop, and every time we exit the command
1399 loop and reenter. Before, the cleanups from the startup sequence
1400 were being left undone until the first error!
1401 (command_loop): Rename do_nothing cleanup to command_loop_marker
1402 so we can see it easily when examining the cleanup chain.
1403 (init_signals): Add another do_nothing for signal handling.
1404 (quit_command): Only try to kill target if it has execution.
1405 Problems in the target stack got us into a state where
1406 inferior_pid was nonzero but none of the targets had execution.
1407 In this state you couldn't exit gdb.
1409 * dbxread.c: Two changes from Peter Schauer.
1410 (echo_command): Fflush output after an echo command.
1411 (show_history): Pass all args to cmd_show_list.
1413 * utils.c (init_malloc): Call mtrace to turn on tracing
1414 if the environment variable MALLOC_TRACE is set to a file name.
1415 * mtrace.c: Add source file which provides a log of every malloc,
1416 free, and realloc to a trace file.
1417 * mtrace.awk: Add source file which analyzes the trace file.
1418 * Makefile.dist (GNU_MALLOC, MALLOCSRC): Add mtrace.{c,o,awk}.
1419 (VERSION): Roll to 3.94.3.
1421 * breakpoint.c (breakpoint_1): Add a space to "i watch" output.
1422 (check_duplicates): Don't bother with watchpoints.
1423 (set_raw_breakpoint): Comment about danger of this routine.
1424 (watch_command): Parse and eval all args before calling
1427 * solib.c (find_solib): Avoid error in referencing memory to
1428 see if any more shared libraries have been added. This is
1429 particularly useful if the target has terminated. Bug reported
1432 Changes from Peter Schauer <pesrem@regent.e-technik.tu-muenchen.de>
1433 in bringing up 3.94.2 on the Sun-3.
1435 * Makefile.dist: Include CFLAGS in rule for cplus-dem.o.
1436 * breakpoint.c (enable_breakpoint): Check for valid watchpoint
1437 expression (in scope) before reenabling watchpoint.
1438 * signame.c (init_sigs): Add missing declaration of i, fix
1439 sys_siglist declaration.
1440 * source.c (list_command): Fixed range computation to use
1442 * stack.c (backtrace_command): Do not allow command if target has
1443 no stack, print informative error message.
1444 * target.c (target_command): Do not write into command line
1445 because this fails if the target command is used in a user defined
1446 command. [This change was enhanced by gnu to support any-
1447 unique-prefix matching on target names.]
1448 * valops.c (value_struct_elt): Avoid infinite loop on an
1449 erroneous attempt to print the member of function (try p main.p).
1451 Mon Apr 1 17:05:45 1991 John Gilmore (gnu at cygint.cygnus.com)
1453 * expread.y (name_no_typename): Avoid reduce/reduce errors
1454 caused by ambiguity in handling NAME_OR_INT and NAME_OR_UINT.
1455 Since the GDB parser really doesn't use name_no_typename in a
1456 name-only context, the parser can't tell the diff between
1457 names and numbers here. Avoid allowing a name_no_typename
1458 to be a NAME_OR_*INT to resolve the conflict.

1462 Bugfixes from Mark Fox (markf@wrs.com) (test=testField.c):
1464 * valprint.c (val_print_fields): bitfield printing didn't handle
1465 byte order. Indirect through a few more fns to cope.
1467 * values.c (modify_field): also cope with byte order.
1469 Sat Mar 23 10:02:21 1991 John Gilmore (gnu at cygint.cygnus.com)
1471 Cleanup for release 3.94.2:
1473 * Makefile.dist: Pull REMOTE_OBS. Fix saber includes for BFD
1474 include files. Roll version to 3.94.2.
1476 * coffread.c (init_stringtab): Read length into unsigned char
1477 array before swapping; don't assume 32-bit longs.
1479 * target.c (target_info): Don't bother with get_sym_file, just use
1480 the symfile global variable.
1481 * symtab.h, symfile.c (get_sym_file): Delete it.
1483 * dbxread.c (dbx_symfile_init): Don't depend on long == 4 bytes.
1484 (define_symbol): Set symbol line number to 0 if not gcc-compiled.
1485 (read_type): Replace one more error() with complain().
1487 * mipsread.c (parse_partial_symbols): Replace printf with complain.
1489 * i960-tdep.c: Fix copyright attribution.
1491 * config.gdb: Quote all backquotes in doublequotes. You can
1492 quote me on that. BSD 4.4 shell found this one.
1494 * infptrace.c (throughout): The third argument to ptrace is an
1497 * infrun.c (wait_for_inferior): When program has terminated, we
1498 have to call target_terminal_ours before we pop that target off
1499 the stack (e.g. before a call to target_kill or
1500 target_mourn_inferior). This fixes problem where a program
1501 terminates, then GDB stops for (tty output) and you have to type
1502 "fg" to the shell to resume it. FIXME: This code for what to
1503 do after termination really should be in normal_stop instead.
1505 * gdbcore.h (read_memory_check): Change declaration; it changed
1508 * terminal.h: Include <sgtty.h> before <sys/ioctl.h>, since in BSD
1509 4.4 prereleases, this avoids a bug in their sgtty compatability
1511 * remote.c: Use terminal.h rather than hand-rolling the same.
1513 * signame.c, signame.h (psignal): Arg is unsigned, not int.
1514 * utils.c (strsave, strstr): Fix arg types.
1515 * valprint.c (val_print): lint
1517 MIPS symbol table support from Per Bothner:
1519 * symfile.c (symtab_fns): Remove initializer table that needs to
1520 be hacked for each new symbol file format supported.
1521 (add_symtab_fns): New function, chains symbol table
1522 handlers into the global list.
1523 (symfile_init): Search this list.
1524 * symfile.h: Add next pointer, declare add_symtab_fns.
1525 * coffread.c (_initialize_coffread): Call add_symtab_fns.
1526 * dbxread.c (_initialize_dbxread): Call add_symtab_fns.
1528 * mipsread.c (psymtab_to_symtab_1): return void instead of (struct
1529 symbol *). Thus, we no longer need the hack to trash
1530 pst->filename. Good, since that hack confused code in symfile.c!
1532 (reorder_symtabs, destroy_all_symtabs): Removed static
1533 all_symtabs, which was used to qsort symtabs in reorder_symtabs.
1534 Instead, the latter now uses a temporary array (stack-allocated
1535 from an obstack, and then freed).
1537 (parse_symbol): Added a hack to fix up BLOCK_{START,END} if they
1538 haven't been set in the outermost stBlock of a procedure. This was
1539 a problem with f77 binaries on Ultrix 4.?.
1541 (new_symtab, new_symbol, new_type): Continue changing code to use
1542 obstacks more and otherwise conform to dbxread internal style.
1543 Made the free_code of symtabs be free_linetable (as in dbxread)
1544 instead of free_contents. This implies memory leaks when reading
1545 a new symbol table, until the conversion is finished. Did change
1546 (struct symbol) and (struct type) to be allocated on the
1547 symbol_obstack. Blocks and blockvectors are among the things
1550 * mipsread.c (parse_partial_symbols, parse_fdr): It hasn't been
1551 tested much, but it solved one problem (reported by Meissner), and
1552 cleans up some other things. The problem happened when an
1553 included file contains actual code (functions) and not just
1554 definitions. The mips coff is a little inconvenient there, since
1555 it may cause a procedure to be mapped to the wrong psymtab.
1557 * mips-tdep.c (heuristic_proc_desc): Minor cleanup.
1558 * mips-xdep.c (fetch_core_registers): Minor cleanup. FIXME,
1559 this will need work for the new core paradigm.
1561 Opcode patches from the net:
1563 * mips-opcode.h: fix incorrect disassembly of the mfc1, cfc1, and
1564 ctc1 instructions. Also, the cvt.d.w and cvt.s.w instructions were
1565 missing altogether - they are added here. From Bruce Bauman.
1566 * mips-opcode.h: The low mask for C0 instructions was too small.
1567 From Garrett Lau. I modified the fix to check the entire 32-bit
1570 * ns32k-opcode.h: Fix opcodes for deiw and deid. From Bruce
1573 Thu Mar 21 12:56:46 1991 John Gilmore (gnu at cygint.cygnus.com)
1575 Roll in changes from Per Bothner (Tue, 25 Sep 90 11:11:04):
1577 * dbxread.c (read_type): Pointer subtraction (value_sub in
1578 valarith.c) sometimes failed because the types of the
1579 pointers being subtracted were not identical.
1580 These differed because dbxread.c was allocating pointer types
1581 using dbx_alloc_type+smash_to_pointer_type instead of
1582 lookup_pointer_type. I failed to find a justification for the
1583 former, so I changed it to use the latter. Similarly, I
1584 replaced smash_to_function_type by lookup_function_type,
1585 and smash_to_reference_type by lookup_reference_type.
1587 * mipsread.c (parse_symbol, upgrade_type, parse_procedure,
1588 _initialize_mipsread): corresponding changes.
1590 * symtab.c (smash_to_{pointer,reference,function}_type): eliminate.
1592 * source.c (mod_path): Do tilde_expand on each component of the path,
1593 rather than on the (list of) paths as a whole.
1594 (print_source_lines): Set first_line_listed in addition to
1595 current_source_symtab and current_source_line. If the source was
1596 not findable, after a "dir" command to fix the problem,
1597 a "list" would get the wrong lines.
1599 While I was there... (gnu):
1601 * dbxread.c (read_type): Change error to complaint.
1603 Thu Mar 21 12:56:46 1991 John Gilmore (gnu at cygint.cygnus.com)
1605 First attempt at detailed understanding of symbol table memory alloc.
1607 * dbxread.c (dbx_symfile_read): Free our string table if we
1608 aren't the mainline. Free the "info" struct since we're done with
1610 (init_psymbol_list): Free any previously allocated psymbol lists.
1611 (): FIXME: Should realloc-down the psymbol lists when done reading
1612 the main symbol file?
1614 * symmisc.c (free_symtab): Free fullname field too.
1616 * xm-hp300hpux.h (USG): #undef then #define so Makefile can -D.
1617 (REGISTER_ADDR): Make result type unsigned int.
1619 * xconfig/{i386*,hp300hpux,altosgas,altos}: All config files that
1620 define REGEX must also define REGEX1 (its dependency).
1622 Tue Mar 19 21:28:57 1991 John Gilmore (gnu at cygint.cygnus.com)
1624 * tconfig/i960: No longer works, points you at vxworks960 or
1627 * xgdb.c, XGDB-README: Remove file. Users can get the much
1629 * Makefile.dist: Remove all trace of xgdb.
1631 * breakpoint.c (breakpoint_1): Pass demangle arg to
1632 print_address_symbolic.
1633 (clear_breakpoints): Remove unused function.
1634 (breakpoint_re_set_one): Guts of breakpoint_re_set.
1635 (breakpoint_re_set): Use catch_errors to do them all anyway.
1637 * gdb-int.texinfo (Host versus Target): Add section on what is
1638 a "host" feature versus what is a "target" feature.
1640 * infcmd.c (path_command, path_info): Handle the PATH variable
1641 (object search path) as conveniently as the source search path.
1642 * environ.c (set_in_environ): Set some vars in GDB's environment,
1643 in addition to the child's. PATH, G960BASE, G960BIN for starters.
1644 * source.c (mod_path): New function, from guts of
1645 directory_command, modifies a path. Used by path_command.
1646 (directory_command): Call it.
1647 * defs.h (strsave): Declare.
1649 * utils.c (sevenbit_strings): Add new printing option.
1650 (printchar): Use it.
1651 (strsave): Provide this handy helper routine.
1652 (set_width_command): Rename set_screen_width_command.
1653 (_initialize_utils): "set screen-width" => "set width";
1654 "set screen-height" => "set height"; add sevenbit-strings.
1656 * infcmd.c (do_registers_info): Print floating point registers
1657 in raw hex as well as float format, regardless of whether it is
1658 a "virtual" convertible register.
1659 * tm-sparc.h (PRINT_REGISTER_HOOK): Print every pair of float
1660 regs as a double, just in case it's being used that way.
1661 * values.c (unpack_long): Comment on array/function coercion.
1662 (unpack_double): Argument is in target byte order now. For
1663 integer arguments, just call unpack_long and float the result.
1664 * m68k-tdep.c: include defs.h for "const" handling.
1665 * remote-nindy.c: Use ieee-float stuff.
1666 (nindy_fetch_registers): Unpack double regs to host double, then
1668 (nindy_store_registers): Pack extendeds to host double, flip
1669 around by misusing unpack_double, send as target double.
1671 * tm-vxworks68.h (FRAME_CHAIN): Handle current frame pointer of
1672 zero, as when stopped at the first instruction of a process.
1674 * blockframe.c: Fix filename in comment (param.h => tm.h).
1675 * sparc-tdep.c (skip_prologue): More explicit nudging comments.
1676 * tm-68k.h: Fix typos.
1678 Fri Mar 15 01:09:34 1991 John Gilmore (gnu at cygint.cygnus.com)
1680 Changes from a bringup on the DEC Vax under Ultrix 4.0.
1682 * coredep.c (fetch_core_registers): Pass end-address of register
1683 section to register_addr as expected. Don't call supply_register
1684 if we'd just pass it garbage.
1686 * dbxread.c (read_dbx_symtab): Skip N_NSYMS on Ultrix.
1688 * exec.c (xfer_memory): Use boolean xfer_fn result, not int.
1690 * target.c (push_target, target_info): Cast enums to int for < or
1693 * stack.c (print_frame_info): Identify source file & line
1694 even if we can't print it.
1696 * xm-vax.h (MISSING_VPRINTF): No longer missing in Ultrix V4.0.
1698 Sat Mar 9 10:08:20 1991 John Gilmore (gnu at cygint.cygnus.com)
1700 Clean up IEEE floating point support.
1702 * ieee-float.h: New file.
1703 * ieee-float.c: Write real routines to convert between host
1704 doubles and various target IEEE extendeds.
1705 * m68k-xdep.c: Eliminate assembler code for extended floats.
1706 * xconfig/{3b1,altos,altosgas,hp300bsd,isi,news,news1000,sun2os3,
1707 sun2os4,sun3,sun3os3,sun3os4}: Eliminate use of m68k-xdep.o.
1708 * tm-i960.h, tm-68k.h (REGISTER_CONVERT_TO_VIRTUAL,
1709 REGISTER_CONVERT_TO_RAW): Use ieee_extended_to_double and
1710 double_to_ieee_extended.
1711 * i960-tdep.c: Define ext_format_i960.
1712 * m68k-tdep.c: Define ext_format_68881.
1713 * sparc-tdep.c: Define ext_format_sparc, though unused.
1714 * Makefile.dist (HFILES): Add ieee-float.h.
1715 * inftarg.c: #include "ieee-float.h" for the REGISTER_CONVERT
1718 Obsolete the "coffstrip" program in favor of using BFD's strip.
1720 * nindy-share/coffstrip.c: Remove file.
1721 * nindy-share/nindy.c (coffstrip): Routine to run bfd_strip.
1722 * Makefile.dist: Remove references to nindy-share/coffstrip.c.
1723 * tconfig/nindy960: Remove reference to coffstrip.o.
1725 * Makefile.dist: Roll version number to 3.94.1 (not yet final).
1727 Wed Mar 6 09:56:45 1991 John Gilmore (gnu at cygint.cygnus.com)
1729 * symfile.h: Add symfile_bfd, common between dbxread and coffread.
1730 * dbxread.c: Remove static symfile_bfd.
1731 * infcmd.c (do_registers_info): Add PRINT_REGISTER_HOOK, though
1733 * inftarg.c (child_detach): Pop the child_ops vector if the
1734 detach is successful.
1735 * remote-nindy.c (nindy_create_inferior): Don't push a new
1736 nindy_ops since nindy uses the same one for execution and memory
1738 * core.c (core_ops): Use child_attach and child_create_inferior
1739 rather than default attach and create_inferior functions.
1741 Handle floating point registers in core files.
1743 * sparc-xdep.c (fetch_core_registers): Rewrite for float support.
1744 * sun3-xdep.c (fetch_core_registers): Rewrite for float support.
1745 This version untested since BFD doesn't yet support sun3 core
1747 * hp300hpux-xdep.c: Rewrite fetch_core_registers to new calling
1748 conventions. Fix comments and style. This version has not
1749 been compiled yet, since we have no HP inhouse.
1750 * core.c (get_core_registers): Look for two sections, ".reg"
1751 and ".reg2", and pass both to fetch_core_registers sequentially.
1753 Revise directory path yet again.
1755 * source.c (forget_cached_source_info): Not static any more.
1756 (init_source_path): New default source path is "$cdir:$cwd".
1757 (dir_command): Handle variable arguments ($cdir, $cwd).
1758 (source_info): Print "Compilation directory" rather than
1759 "Originally compiled in" to remind people of $cdir.
1760 (openp): If the path contains $cwd, use current directory.
1761 (open_source_file): If compilation directory is known, replace
1762 first $cdir in path with the compilation directory.
1763 (print_source_lines): Even if we can't print the lines, set the
1764 current symtab and line for future commands like "info source" or
1765 "breakpoint". Also, error message now contains the file name,
1766 line number, and file access error message.
1767 (_initialize_source): Fix help text to describe changes.
1768 * main.c (cd_command): Forget cached source info when we chdir.
1769 * utils.c (strstr): Add simple implementation.
1771 Tue Mar 5 01:41:40 1991 John Gilmore (gnu at fowanton.cygnus.com)
1773 * coffread.c (read_one_sym, init_linetable, init_stringtab):
1774 Byte-swap COFF symbol tables if necessary when reading them in.
1775 Use complain() to replace error message in one spot. Needs
1776 corresponding change in bfd/coff-code.h to make some symbol
1777 swapping routines non-static.
1779 Mon Mar 4 00:53:40 1991 John Gilmore (gnu at cygint.cygnus.com)
1781 Merge changes from Eirik Fuller, for UTek.
1783 * defs.h (errno): Add declaration.
1784 * altos-xdep.c, arm-xdep.c, convex-xdep.c, gould-xdep.c,
1785 hp300hpux-xdep.c, infrun.c, inflow.c, infptrace.c, i386-tdep.c,
1786 i386-xdep.c, pyr-xdep.c, mips-xdep.c, remote-eb.c, remote-nindy.c,
1787 remote-vx.c, source.c, standalone.c, stuff.c, sun386-xdep.c,
1788 symmetry-tdep.c, symmetry-xdep.c, umax-xdep.c, utils.c: Eliminate
1789 declarations of errno.
1791 * remote-eb.c: Define B19200 and B38400 as EXTA and EXTB.
1793 * remote-vx.c: Include <sys/time.h> for UTek; Sun gets it via
1794 <rpc/rpc.h> and <rpc/types.h>.
1796 Sat Mar 2 15:47:55 1991 John Gilmore (gnu at cygint.cygnus.com)
1798 * i960-tdep.c (examine_prologue): Add new argument limit,
1799 which stops the scan at the end of the prologue, or at the PC.
1800 This fixes a problem where it walks down into the code for the
1801 user's statements if that code looks like function prologues.
1802 Mark Fox and I have been bouncing this code back and forth, making
1803 small changes to it. Callers changed to match.
1805 Tue Feb 26 01:47:07 1991 Cygnus John Gilmore (cygnus at yuba)
1807 Cleanup for gdb-3.94 release final:
1809 * Makefile.dist: Remove remote-vx.c, remote-nindy.c, and all
1810 the .c files from vx-share and nindy-share, from the various
1811 macros, since they are not found via ALLDEPFILES.
1812 (SFILES): Add tm-i960.h.
1813 (alldeps.mak rule): Break out ALLDEPFILES_MAINDIR and
1814 ALLDEPFILES_SUBDIR. List all the nindy and vxworks subdir files
1816 (TAGFILES_MAINDIR): Change ALLDEPFILES to ALLDEPFILES_MAINDIR.
1817 (gdb.tar.Z): Use ALLDEPFILES_SUBDIR as well as SFILES_SUBDIR.
1819 Mon Feb 25 16:02:35 1991 Cygnus John Gilmore (cygnus at oldman)
1821 * am29k-tdep.c: Add contribution line.
1822 (examine_prologue): Cache information about function prologues in
1823 the misc-function-vector to avoid lots of references over the
1824 serial line while examining instructions.
1826 * core.c (core_close): New function made from cleanup_core.
1828 * core.c, exec.c, inftarg.c, remote-eb.c, remote-nindy.c,
1829 remote-vx.c, remote.c, target.c, target.h,
1830 Update target_ops vector to add attach, close, and load entries.
1831 Use add_syms_addr_command, not add_file_addr_command, for
1832 add_file. Break out close routine from existing code.
1834 * dbxread.c (really_free_pendings): Don't free pending_blocks;
1835 they are in an obstack.
1836 (read_dbx_symtab): Relocate end_of_text_addr in the psymtab.
1838 (define_symbol): Add symbol type parameter; change callers;
1839 pass type parameter to DBX_PARM_SYMBOL_CLASS macro to allow
1840 it to influence the symbol class on the i960.
1841 (define_symbol): Swap LOC_CONST's into target byte order.
1843 * exec.c (exec_close): New function.
1844 (exec_file_command): Call it.
1846 * findvar.c (read_relative_register_raw_bytes): Doc byte order,
1847 Fix byte order of frame pointer.
1848 (read_var_value): Result of 0 if var's value can't be found,
1849 e.g. missing FRAME_ARGS_ADDRESS. Byte-swap LOC_CONST and
1850 LOC_LABEL values to target order. Add LOC_LOCAL_ARG.
1851 (locate_var_value): Use read_var_value and use its lazy address
1852 as the location of the var's value. Lint.
1854 * i960-pinsn.c (next_insn): Add routine from vxgdb for scanning
1857 * i960-tdep.c (arg_address, i960_frame_find_saved_regs): Remove
1858 obsolete Intel versions in favor of vxgdb versions.
1859 (check_host, byteswap, byteswap_val, reorder_val): Eliminate
1860 code dealing with byte order of values, which Intel did in host byte
1861 order rather than gdb-4's target byte order.
1862 (i960_frame_chain_valid): Move to nindy-tdep.c.
1863 (examine_prologue, skip_prologue, frame_find_saved_regs,
1864 frame_args_address, leafproc_return, saved_pc_after_call,
1865 pop_frame): Add vxgdb versions from Mark Fox.
1866 (examine_prologue, frame_struct_result_address): Add code
1867 to deal with the saved value of G13 (struct return address
1869 (frame_args_address): Modify Mark's version to prefer the
1870 saved value over the current value in the topmost frame.
1871 Cache result in the frame info to avoid performance hair in
1873 (print_fault): Add gdb960 code for printing faults.
1874 (_initialize_i960): Actually call check_host.
1876 * ieee-float.c (ieee_extended_to_double, ieee_double_to_extended):
1877 add stub routines. FIXME, these currently just return zero!
1879 * infcmd.c (program_info): Use PRINT_RANDOM_SIGNAL.
1880 (attach_command): Call target_attach, not target_open, now.
1882 * infrun.c (normal_stop): Make global, not static, for vx_attach.
1883 (child_attach): Rename from child_open.
1884 (wait_for_inferior): Use PRINT_RANDOM_SIGNAL. If stop_pc is zero,
1885 don't confuse it with a zero step_resume_break_address.
1887 * inftarg.c (child_detach): Eliminate inferior_pid test.
1888 (child_files_info): Clean up message a bit.
1889 (child_ops): Use child_attach, not child_open, to attach.
1891 * mem-break.c: #ifdef out the whole file if BREAKPOINT is not
1892 set (e.g. on VxWorks or NINDY). Move read_memory_nobpt from
1893 findvar.c to here, since it depends on the contents of the
1894 shadow_contents of breakpoints, but keep if #if 0 since it is
1897 * nindy-tdep.c: New file, contains nindy_frame_chain_valid, moved
1900 * printcmd.c (address_info): Handle LOC_LOCAL_ARG. Lint.
1901 (ptype_command, display_command): Eliminate have_inferior_p and
1902 have_core_file_p in favor of target_has_stack or
1903 target_has_execution.
1904 (print_frame_args): Handle LOC_LOCAL_ARG. Eliminate duplicate
1905 code for actually finding the values of arguments, though we still
1906 keep track of the maximum stack offset for use in printing unnamed
1907 arguments. Handle missing FRAME_ARGS_ADDRESS.
1909 * remote-nindy.c (i960_print_fault): Move to i960-tdep.c.
1910 (struct nindy_regs): Define registers passed to/from nindy.
1911 (nindy_fetch_registers, nindy_store-registers): Translate between
1912 nindy and GDB formats for the registers.
1913 (dcache_init): Statically allocate the cache, since it was being
1914 allocated by a malloc that was never freed anyway.
1915 (nindy_create_inferior): Error, not core dump, if no exec file.
1916 (nindy_before_main_loop): Use target_load, not target_add_file.
1918 * remote-vx.c (net_load): Specify large timeout for load
1919 requests. Allow user to break out with INTERRUPT.
1920 (net_break): Remove useless code, clean up. Change callers.
1921 (parse-args, skip_white_space, find_white_space): Clean up arg
1922 parsing to cope with quoted strings.
1923 (net_wait, net_quit): Never call error, just return status.
1924 (vx_read_register, vx_write_register): Cleanup status checking.
1925 #ifdef the code based on which CPU we are using (960 or 68k),
1926 FIXME, this should be completely general but it isn't yet.
1927 (vx_xfer_memory, vx_resume): Cleanup status checking.
1928 (vx_run_files_info): Improve message.
1929 (vx_load_command): Renamed from vx_add_file_command. Allow load
1931 (net_ptrace): Remove unused routine.
1932 (vx_wait): Adopt code from vxgdb960 to cope with broken
1933 connections to target machine and prompt to disconnect. Remove
1934 debug printouts. Map some EVENT_'s to SIGnals.
1935 (add_symbol_stub, vx_open): Print names of object files we found,
1936 and "ok" if we read their symbols OK. Clarify output in general.
1937 (vx_attach, vx_detach, vx_kill): Add these commands.
1938 (vx_convert_from_virtual, vx_convert_to_virtual): Simplify.
1939 (vx_run_ops): Turn off all_mem, to avoid spurious msg in the
1940 "info files" output, and create_inferior, since we already have
1943 * stack.c (frame_info): Replace Frame_unknown with 0.
1944 (print_frame_arg_vars): Handle LOC_LOCAL_ARG.
1945 (return_command): Pop until the PC matches as well as the FP,
1946 so it works even if the FP is shared with another function,
1947 as in "frameless" or "leaf" procedures.
1949 * symfile.c (load_command): renamed from add_file_target_command.
1950 (add_syms_addr_command): renamed from add_file_addr_command.
1951 (add_syms_command): Stub to call target_add_syms.
1952 (_initialize_symfile): Change command names and descriptions,
1953 add-file => add-syms, and load from alias to its own command.
1955 * target.c (kill_or_be_killed, maybe_kill_then_attach,
1956 maybe_kill_then_create_inferior): Default for attempts to start
1957 a process, if one is already running, is to ask about killing
1958 it and retry if yes.
1959 (upstack_create_inferior): #if-0 it, strata obsolete it.
1960 (push_target, unpush_target, pop_target): to_close() a target
1961 before unstacking it.
1962 (target_info): Renamed from target_files_info.
1963 (_initialize_targets): Rename "i files" as "i target", accessible
1966 * target.h: Improve comments about the target_ vectored routines.
1968 * tm-i960.h: Remove NINDY-specific stuff to tm-nindy960.h.
1969 Convert commenting style to standard GNU style.
1970 (DBX_PARM_SYMBOL_CLASS): allow LOC_LOCAL_ARG's to be recognized.
1971 (SKIP_PROLOGUE): No longer a no-op.
1972 (SAVED_PC_AFTER_CALL): Now handles leaf procedures.
1973 (*_REGNUM): Sort register numbers.
1974 (REGISTER_BYTES, REGISTER_BYTE, REGISTER_RAW_SIZE,
1975 MAX_REGISTER_RAW_SIZE, REGISTER_CONVERTIBLE,
1976 REGISTER_CONVERT_TO_VIRTUAL, REGISTER_CONVERT_TO_RAW): Float regs
1977 are now 10 byte extendeds, not 8 byte doubles.
1978 (FRAME_CHAIN_VALID): Make this config-dependent, since it differs
1979 for nindy versus vxworks targets. FIXME, this should possibly go
1980 in the target vector.
1981 (EXTRA_FRAME_INFO, INIT_EXTRA_FRAME_INFO): Cache both
1982 frame_saved_regs and arg pointer with each frame.
1983 (FRAMELESS_FUNCTION_INVOCATION): New leafproc support.
1984 (FRAME_ARGS_ADDRESS): Use cached result.
1985 (FRAME_ARGS_ADDRESS_CORRECT): New, avoids g14 guessing.
1986 (FRAME_FIND_SAVED_REGS): Change arg to subsidiary fn.
1987 (PRINT_RAMDON_SIGNAL): Call print_fault.
1988 (POP_FRAME): Now works.
1990 * tm-nindy960.h: Break this off tm-i960.h. NINDY-specific
1991 option parsing and startup; STACK_END_ADDR, FRAME_CHAIN_VALID,
1992 BREAKPOINT, and DECR_PC_AFTER_BREAK are here.
1993 (ADDITIONAL_OPTION_HANDLER): use target_load, not
1996 * tm-vxworks960.h: Break this off tm-i960.h. VxGDB specific
1997 startup; DECR_PC_AFTER_BREAK, and FRAME_CHAIN_VALID are here.
1999 * valarith.c (value_subscripted_rvalue): Avoid handling
2000 floats and doubles specially; it gave alignment errors. Lint.
2002 * valops.c (value_of_variable, value_of_this): Error if unknown
2005 * valprint.c (print_floating): Bcopy rather than pointer-deref,
2006 to avoid alignment problems.
2007 (value_print): Handle unknown value address.
2008 (cplus_val_print): Two args are ignored; remove them. Change caller.
2009 (val_print): Use unpack_long rather than pointer-deref.
2012 (unpack_long, unpack_double): Use bcopy rather than pointer-deref
2013 to avoid alignment problems.
2014 (value_being_returned): Error if return value unknown.
2015 (set_return_value): Add bogosity warning, FIXME. *
2017 * TODO: A woman's work is never done.
2019 * Makefile.dist: Distribute REMOTE_OBS into tconfig files.
2020 Separate INCLUDE_CFLAGS for use with lint. Add LINTFILES.
2021 Add ieee-float.o to OBS.
2022 * tconfig/{nindy960,vxworks68,vxworks960}: Include the desired
2023 REMOTE_OBS remote-interface files in the TDEPFILES and TM_FILE.
2024 * tconfig/i960: FIXME. Half-merge, produce warning if config'd.
2026 Changes to generalize the VxWorks RPC protocol slightly, to handle
2027 i960 as well as 68000.
2029 * vx-share/dbgRpcLib.h (VX_SOURCE_STEP): Add.
2030 * vx-share/reg.h: Produce i960 regs #ifdef I80960
2031 * vx-share/xdr_ptrace.c: Skip FPA registers if 960.
2032 * vx-share/xdr_rdb.h: Add SOURCE_STEP struct and xdr decl.
2033 * vx-share/xdr_rdb.c: Add xdr_SOURCE_STEP routine.
2034 * vx-share/xdr_regs.c: Add xdr_regs, xdr_fp_status, xdr_ext_fp
2035 for i960. Change xdr_vectors to xdr_opaques for 68k registers,
2036 so they will move in target byte order rather than network
2037 byte order (happens to be the same).
2039 Mon Feb 25 03:41:44 1991 John Gilmore (gnu at cygint.cygnus.com)
2041 * tm-convex.h (END_OF_TEXT_DEFAULT): Remove #if 0'd block.
2043 Sun Feb 24 00:55:53 1991 John Gilmore (gnu at cygint.cygnus.com)
2046 Add contribution lines to various files, showing where they
2049 * breakpoint.c (break_insn, check_break_insn_size,
2050 read_memory_nobpt): Remove to mem-break.c.
2052 * xm-*.h, param-no-tm.h, tm-29k.h, valprint.c: Change BYTE_ORDER to
2055 * tm-29k.h (STAB_REG_TO_REGNUM): Warn user if symbol table
2056 entry has bad register number. This change is not
2057 tested in this release, FIXME.
2059 * frame.h: Eliminate Frame_unknown in favor of a simple zero.
2062 * value.h: Force value's contents field to be aligned to hold
2063 at least a double or a long long (if supported). This avoids
2064 doing bcopy's in and out of the contents field.
2066 (step_1): Avoid coredump under obscure circumstances when we
2069 * symtab.h (misc_info): Add field to misc function vector for
2070 any kind of cached information the target code desires. AMD
2071 29000 uses this to avoid repeating examine_function_prologue's.
2073 * coffread.c: Lint. Remove static symfile, read_section_header.
2074 core.c (have_core_file_p): Lint: remove.
2075 expprint.c (print_subexp): Lint.
2076 infptrace.c, valops.c, valprint.c: lint.
2078 Roll in changes from vxgdb-5.0.1:
2080 * symtab.h: Comment byte order of each address class. Add
2081 LOC_LOCAL_ARG for frame-relative args (960).
2082 expread.y: Use LOC_LOCAL_ARG where LOC_ARG is used.
2083 symtab.c, symmisc.c: ditto.
2085 * infrun.c (init_wait_for_inferior): Clear stop_signal.
2087 * remote.c (remote_resume): Error if resume with a signal.
2089 * symfile.c (prim_record_misc_function): Clear misc_info.
2090 (fill_in_vptr_fieldno): Check stub type of arg.
2092 * valops.c (value_cast): Avoid looking up names of types whose
2093 name we don't know, to prevent coredump. Sun CC produces typedef
2094 rtx and the name of *rtx is zero...
2096 Mon Feb 18 21:16:25 1991 John Gilmore (gnu at cygint.cygnus.com)
2098 Roll in changes from final AMD 29000 port (Tiemann).
2100 tconfig/am29k: Add COFF_ENCAPSULATE and TARGET=TARGET_AM29K
2101 for ../include/a.out.encap.h. This might not work now that BFD
2102 is separately compiled. Instead, BFD support for encap will have
2103 to translate machine type 29k into the right COFF_MAGIC.
2105 * infcmd.c: Remove references to inferior_pid that aren't used
2106 in actual ptrace calls; use target_has_execution, etc.
2107 (have_inferior_p): Remove function.
2108 (program_info): Print target info rather than "process number";
2109 avoid gratuitous messages unless from_tty.
2110 (run_stack_dummy, finish_command): Set proceed_to_finish.
2111 infrun.c: Remove inferior_pid refs. Decl & init proceed_to_finish.
2112 main.c: Lint. Lose have_inferior_p().
2113 inferior.h (have_inferior_p): Remove, lint.
2114 (proceed_to_finish): Add flag to ask that all regs be saved
2115 by normal_stop, for the few commands that need it, speeding up
2116 serial I/O. Add comments to stop_registers.
2118 * remote-eb.c: Remove newline from breakpoint message we grep
2119 for. Never time out when running the user program.
2123 Wed Feb 13 15:34:40 1991 John Gilmore (gnu at cygint.cygnus.com)
2125 Roll in changes from vxgdb-5.0.1:
2127 * dbxread.c (read_dbx_symtab): If we encounter a "FORTRAN COMMON"
2128 symbol in its raw form, we are processing an unlinked ".o" file.
2129 See if the target environment has assigned it an address, using
2130 target_lookup_symbol (VxWorks does), and enter it into the symtab
2133 * tm-vxworks.h (FRAME_CHAIN, FRAME_CHAIN_VALID): Override usual
2134 68k versions for a simpler version that assumes zero FP at bottom.
2135 Fixes bug of truncated stack reports.
2137 * target.h (target_lookup_symbol): Define this routine's args
2138 and result, finally.
2140 * target.c (nosymbol): Default routine for target_lookup_symbol.
2141 (target_default): Default lookup_symbol and call_function too.
2142 (files_info): Only print has_all_memory warning if a non-dummy
2145 * remote-vx.c (vx_read_register, vx_convert_to_virtual,
2146 vx_convert_from_virtual): If target does not have floating point,
2147 zero register "values", and avoid doing cross-net conversions.
2148 (vx_lookup_symbol): Rename net_lookup_symbol, add to vectors.
2149 (vx_open): Rearrange code that attaches to target and reads
2150 symbols for all loaded modules, to work if some of the modules
2151 are not accessible. Add symbol_stub() and add_symbol_stub()
2152 as callbacks from catch_errors(). Allow connect attempt to be
2153 interrupted painlessly with ^C (FIXME, there are still some bugs
2154 if the interrupt happens during symbol reading.). Print
2155 final message with puts_filtered, since symbol messages are
2160 * main.c (catch_errors): Only print errstring if non-null.
2161 (command_loop): Avoid an ioctl per command to test ISATTY.
2163 * remote-vx.c (net_load): make static; avoid sophomoric msg.
2164 (vx_xfer_memory): Return correct result!
2165 (vx_files_info): Indicate whether target has float or not.
2166 (vx_lookup_symbol): Complain, not error, if target gone.
2167 (vx_open): Print "Connected" msg before disabling immediate-quit.
2168 [FIXME: lookup_symbol and vx_open changes need testing.]
2170 target.c, remote-eb.c, inftarg.c, am29k-opcode.h, target.h,
2171 tm-29k.h, tmm-vxworks68.h, symfile.c, gdb-int.texinfo: Add
2172 contributor lines and update copyrights to 1991.
2174 Changes from an attempted H-PUX host port:
2176 * infptrace.c (PT_ATTACH, PT_DETACH): Handle HP/UX, which
2177 defines PT_ATTACH and PT_DETACH but not PT_KILL.
2178 * remote-eb.c (eb_open): Misplaced endif kills sysv H/PUX.
2179 * remote-vx.c: include <sys/time.h> for HPUX.
2180 * hp300hpux-xdep.c (fetch_core_registers): Rewrite old
2181 "core_file_command" routine to BFD regime. May not work yet.
2183 Attempted port of "gdb-3.4 Van Jacobson xgdb" to modern gdb.
2185 * xgdb.c: Replace X10 version with some VJ version.
2186 (FIXME: Its copyright assignment is not on record.)
2187 * xgdb.c: Update include files to X11R4 (Xaw crud).
2188 (xgdb_display_source, create_text_widget): fix call to
2189 get_filename_and_charpos. Rewack source window stuff for X11R4
2190 (gleaned from include files, and "nm's" of binary libraries, since
2191 I had no doc available).
2192 (append_selection, append_selection_word): Disable with FIXME
2193 since R4 changed interface here.
2194 (create_buttons): Add back the old set of buttons.
2195 (xgdb_create_window): Fix call to XtInitialize (&argc not argc).
2197 * Makefile.dist (xgdb, xgdb-init.c): Update for X11R4 on Suns.
2198 Roll VERSION to 3.94 (not yet final though).
2200 Sat Feb 9 09:46:25 1991 John Gilmore (gnu at cygint.cygnus.com)
2202 * obstack.h (obstack_ptr_grow, obstack_ptr_grow_fast,
2203 obstack_int_grow, obstack_int_grow_fast): Eliminate
2204 cast on left of assignment, which gives MIPS cc fits and is
2207 * sparc-pinsn.c (print_insn): Eliminate 'set' test, subsumed by
2208 F_ALIAS. Use printf, not fprintf, when not passing a file
2210 (compare_opcodes): Check that identical instructions have
2211 identical opcodes, complain otherwise.
2213 * sparc-opcode.h (st %fsr): Fix opcode "lose" mask. This
2214 was reported by Roland McGrath.
2215 (unimp): Only match if exactly zero instruction. (Roland)
2216 (branches and traps): Generate all variations of these
2217 instructions with macros, based on a single call that defines
2218 each condition name and its binary representation.
2219 (set): Turn on alias bit, to avoid test in sparc-pinsn.c.
2221 * valprint.c (val_print_fields): Take, and use, format parameter.
2222 This means that "p/x struct" again prints the elements in the
2223 desired format. Changed callers.
2225 * stack.c (frame_info): Use filtered output, and indicate wrap
2226 points. Remove kludgy formatting designed to avoid line wrap.
2228 * utils.c (wrap_here): If the line is already full (because
2229 we had printed a long indent or long wrapped string), do an
2230 immediate newline-and-indent.
2232 * m68k-pinsn.c (print_insn_arg): Bugfix from
2233 ntmtv!thompson@ames.arc.nasa.gov (Mike Thompson): 'bkpt #0'
2234 instruction is incorrectly disassembled as bkpt #8.
2236 * dbxread.c (end_psymtab): Bugfix from Peter Schauer
2237 <pesrem@regent.e-technik.tu-muenchen.de>: If you want to set a
2238 breakpoint in a *.y file gdb will say Reading in symbols for *.y...
2239 and then will dump core (sometimes). I traced it back to an
2240 uninitialized symfile_name in psymtab_to_symtab.
2241 (const_vol_complaint): Add quotes to message.
2242 (define_symbol): Only believe line number if gcc_compiled.
2243 Avoid allocating symbol if we will not return it.
2245 Add target strata support so that newly established targets go
2246 into their right place in the target stack (e.g. a new exec file
2247 doesn't wipe out the ability to access the running process).
2249 * target.h, core.c, exec.c, inftarg.c, remote-eb.c,
2250 remote-nindy.c, remote-vx.c, remote.c, target.c: Add to_stratum
2251 and initialize it properly in all the targets.
2253 * target.h: Document strata. Change return type of push_target.
2255 * target.c (nomemory): new function for dummy memory access.
2256 (tcomplain): Rename complain, now also used in symfile.c.
2257 (push_target): Push targets within strata. New return value shows
2258 whether new target is on top of stack or not. Always keep dummy
2260 (target_files_info): Ignore dummy target.
2262 * core.c (core_open): Warn user, and skip accessing file, if the
2263 core target is not the topmost target in the stack.
2264 * remote-nindy.c (nindy_create_inferior): Avoid unpush_target, now
2267 * remote-vx.c: Remove vx_prepare_to_store from vxworks memory
2268 target_ops, it doesn't belong there since we have no regs there.
2269 Change name of target from machine => memory to clarify.
2271 Thu Feb 7 16:32:09 1991 John Gilmore (gnu at spiff.cygnus.com)
2273 * Freeze version 3.93 for release.
2275 * Makefile.dist: Handle vx-share and nindy-share subdirs
2276 properly when building gdb.tar.Z.
2278 * symtab.c: lint; add no_symtab_msg to consolidate the messages
2279 printed in various places, so I could change just one copy.
2281 * dbxread.c, coffread.c: Change references to bfd->iostream
2282 to cast to FILE *, now that BFD avoids needing types defined
2283 in other header files.
2285 Tue Feb 5 21:39:35 1991 John Gilmore (gnu at cygint.cygnus.com)
2287 * command.c, dbxread.c, expprint.c, infcmd.c, infptrace.c,
2288 infrun.c, printcmd.c, remote-nindy.c, source.c, sparc-tdep.c,
2289 sparc-xdep.c, symfile.h, symmisc.c, utils.c, valprint.c: Lint
2290 (actually gcc -Wall).
2292 * dbxread.c: Remove first_global_sym, last_global_sym, since
2293 they are never referenced.
2295 * defs.h (baud_rate): Declare.
2296 main.c: Define it, and add the -b option to set it.
2298 * gdb-int.texinfo: Add text on how to define a new host or target
2299 architecture, prompted by Per Bothner's questions about MIPS
2302 * gdb.texinfo: Document "complaints". Change doc of -q since
2303 gdb no longer prints the copyright and blurb if you specify a file
2304 name to be debugged (just like Emacs). Add doc for Nindy-specific
2305 command line flags for specifying target serial port and such.
2306 Update copyright to 1991.
2308 * gdbcore.h: Remove a large mass of now-useless crud, since BFD
2309 has taken over for us the job of ripping up executable files. The
2310 crud caused Per Bothner's port to not compile.
2312 * infrun.c (normal_stop): Avoid printing "Program exited
2313 normally" if we are in batch mode. This allows a GDB which
2314 executes a program on a target system, to behave like a Unix
2315 command (input from stdin, output to stdout, no extraneous
2318 * main.c (main): Allow additional machine-dependent command line
2319 options to be specified with the ADDITIONAL_OPTIONS,
2320 ADDITIONAL_OPTION_CASES, ADDITIONAL_OPTION_HELP, and
2321 ADDITIONAL_OPTION_HANDLER macros. Also allow machine-dependent
2322 processing to occur just before the main loop with
2323 BEFORE_MAIN_LOOP_HOOK.
2324 (main): If a "core file" argument is specified, and it is not a
2325 core file, try it as a process ID to attach.
2326 (symbol_completion_function): Attempt to cope with
2327 "show screen-" TAB, not very successfully. This needs more work,
2329 (batch_file): New function, returns whether we are reading
2330 commands from an interactive tty on stdin, or from somewhere else.
2331 Called by normal_stop since it doesn't get from_tty passed down
2332 to it like many commands do.
2334 * remote-nindy.c: Handle command line options for nindy
2336 (nindy_before_main_loop): Prompt user for tty name if they
2337 don't specify it before getting to the interactive command loop.
2339 * tm-i960.c: Add ADDITIONAL_OPTIONS, etc, to handle -O, -brk,
2340 and -r command line options. Also add hook before main loop
2341 to make it easy to specify a tty.
2343 * TODO: More things to do, one done.
2345 Mon Feb 4 23:57:39 1991 John Gilmore and Mike Tiemann (at cygint.cygnus.com)
2347 * dbxread.c: Make complaint() calls pass pointer, not struct.
2348 Add complaints about badly formatted C++ type information
2349 (const/volatile indicator, and parse errors resulting in
2350 error_type). Fix C++ virtual member fn comment.
2351 (read_struct_type): Avoid bumping pointer if we got a parse
2352 error; this prevents our walking beyond the end of a string.
2353 Terminate loop on null char as well as semicolon.
2354 (process_one_symbol): Fix the LBRAC fix so that it uses the
2355 last previous SLINE, FUN, or SO record's PC address. C++ debug
2356 symbols did not have SLINE records in a useful order compared
2357 to the LBRAC records.
2358 (define_symbol): Handle "catch" records.
2360 * symtab.c (check_stub_type): Added new complain
2361 `stub_noname_complain' and added a consistency check to
2362 keep the debugger from crashing when finishing from an
2363 exception frame. A real fix will be needed later.
2365 Sat Feb 2 10:43:05 1991 John Gilmore (gnu at cygint.cygnus.com)
2367 * infcmd.c (attach_command): Make global.
2369 * Makefile.dist (REMOTE_OBS): Make these compile by default,
2370 but make them easy to comment out. Perhaps later they should
2371 be enabled by what CPU you configure for? FIXME.
2372 (VERSION): Roll to 3.93.
2373 (pinsn.o): Remove rule for obsolete file.
2374 (dbxread.o,coffread.o,mipsread.o): Use ${srcdir} explicitly.
2376 Run down a problem that manifested by printing the wrong function
2377 name in stack traces of read_ofile_symtab. Turned out that the
2378 problem was the SunOS 4.1.1 (and previous) C compiler outputs
2379 the LBRAC symbol with an address in the *data* segment, which
2380 blew our binary search through the blocks.
2382 * dbxread.c: Use the complain() facility consistently to bitch
2383 about problems in the symbol file we are reading.
2384 (finish_block): Add code to check the nesting of the blocks;
2385 complain and Procrust them to fit if wrong.
2386 (make_blockvector): Check the order of the blocks, complain
2387 [but don't cope] if wrong.
2388 (process_one_symbol): ifndef SUN_FIXED_LBRAC_BUG, check LBRAC
2389 symbols to be sure their PC value is greater than the last SLINE
2390 (line number) symbol we've seen, complaining and adopting the
2391 SLINE PC value if wrong.
2393 * symfile.h (struct complaint, complaint_root, complain,
2394 clear_complaints): Add.
2395 * symfile.c (complain, complaint_root, clear_complaints): Add
2396 facility to deal with non-fatal complaints and to regularize their
2398 (symbol_file_add): Clear complaint counters to allow new complaints.
2399 (initialize_symfile): Add 'set complaints' and 'show complaints'.
2401 * dbxread.c (dbx_symfile_read): Remember the address and size
2402 of the string table for the main symbol file, so we won't read it
2404 (dbx_psymtab_to_symtab): Fix the check for main symbol file,
2405 to avoid reading the string table yet again. Lint.
2406 (throughout): Improve filtered output, including word wrap.
2407 (read_range_type): Improve Bothner's fix to handle other types too.
2409 * utils.c: Improve line wrap implementation. Handle unlimited
2410 width by making chars_per_line unsigned.
2411 (puts_filtered): New, easy, function.
2413 * defs.h (puts_filtered): add.
2415 * mipsread.c (compare_symbols, sort_symtab): Remove these fns,
2416 call the identical sort_symtab_syms() in symfile.c instead.
2418 * expread.y: Suggest the `file' command rather than `symbol-file'.
2420 * command.h (enum var_types): Add zinteger for seroable
2422 * command.c (do_setshow_command): Handle var_zinteger. Restructure
2423 nested if's into a switch.
2425 * breakpoint.c (bpstat_print): If bpstat "print" flag is not set,
2426 we did not stop because of a breakpoint (it must have been for
2427 some other reason, like a "stepi"), so don't print anything.
2429 * symtab.c: Include <sys/types.h> all the time. Now that BFD
2430 doesn't include <sys/types.h>, old SunOS's require it for
2433 Sat Feb 2 10:39:15 1991 Per Bothner (bothner@cs.wisc.edu)
2435 A test port of gdb-3.92.6 to the Sony NEWS.
2438 Don't normally link in remote- or vx stuff.
2439 Some of it doesn't compile, and it wastes space for 99% of the users.
2440 Remove reference to no-longer-used HAVE_VPRINTF.
2441 Fixed BFD_DEP typo to BFD_DIR.
2443 Fix cast in arg to bfd_h_getlong.
2444 Make char *prefix be const.
2445 Fix how certain range types are mapped into builtin unsigned int types.
2447 Remove 2 #includes. They cause errors (on Sony, at least),
2448 and aren't needed (they wern't in earlier versions).
2450 print_address_symbolic should never demangle labels
2451 (since it prints *assembler-level* labels).
2453 [This was superseded by the change to printcmd below.]
2456 Add some "volatile" return types to avoid warnings.
2457 If MISSING_VPRINTF add vprintf function and not just macro
2458 (since vprintf is used in printcmd.c).
2460 Unless __GNUC__, use obstack_grow instead of obstack_ptr_grow.
2461 (The latter isn't grokked by some PCC-based compilers.)
2463 [This change is in abeyance, we prefer to fix obstack_ptr_grow.]
2465 Make chunk size of dont_print_obstack 32*4 instead of default 4096.
2466 * nindy-share/coffstrip.c
2467 Added some forward declarations (otherwise, gcc complains
2468 about implicit extern redefined as static).
2470 Sun Jan 20 02:38:19 1991 John Gilmore (gnu at cygint.cygnus.com)
2472 Changes inspired by Per Bothner:
2473 * printcmd.c (print_address_symbolic): Take additional parameter
2474 specifying whether to demangle.
2475 (print_address): Pass in asm_demangle to control demangling.
2476 (print_address_demangle): New fn, takes explicit arg to control
2478 * utils.c: Add new vars demangle and asm_demangle, and let them
2480 (fputs_demangled): If !demangle, just print the argument.
2481 (fprint_symbol): If !demangle, just print raw symbol.
2482 * valprint.c (val_print): Call print_address_demangle rather than
2483 print_address, to cause demangling to depend on the global
2484 rather than assembler-level demangling setting.
2485 * WHATS.NEW, gdb.texinfo: Document.
2487 * main.c (show_command): Show all settings if no arg.
2488 (initialize_main): Make "info set" the same as naked "show".
2489 * command.c (cmd_show_list): Handle prefix commands in the
2490 list, and print the name of the setting as well as its English
2491 description and value.
2493 Allow gdb functions to specify where a line should wrap if it
2494 exceeds the size of a terminal line. Use it to make the output
2496 * utils.c (set_screen_width_command): New fn, mallocs a buffer
2497 of the right size when screen width changes.
2498 (set_screensize_command, screensize_info): Remove #if 0'd fns.
2499 (wrap_here): New fn, indicates a point in the output where we
2500 should wrap the line rather than just letting it overflow at a
2502 (fputs_filtered): Implement wrapping.
2503 (n_spaces): New fn, returns a pointer to N spaces.
2504 (print_spaces_filtered): Use n_spaces.
2505 * defs.h (n_spaces): Declare.
2506 * stack.c (print_frame_info): Wrap with 4-space indent after
2507 fn name and before filename and line number.
2508 * printcmd.c (print_frame_args): Wrap with 4-space indent
2509 before each argument name is printed.
2510 * valprint.c (value_print): Wrap with no indentation before
2512 (val_print_fields): Wrap with indentation relative to nesting
2513 level before each field name.
2514 (val_print): Wrap with nesting indentation before array elements.
2515 * command.c (do_setshow_command): Avoid extra newlines,
2516 wrap with 4-space indent around values printed, end with period.
2517 * WHATS.NEW, gdb.texinfo, gdb-int.texinfo: Document.
2519 * breakpoint.c (breakpoint_1): Implement addressprint for
2520 "info breakpoints" display. Change file name and line number
2521 format to " at file:nnn" rather than " (file line nnn)".
2522 * gdb.texinfo: Document.
2525 Fri Jan 18 07:21:25 1991 John Gilmore (gnu at cygint.cygnus.com)
2527 Frozen for gdb-3.92.6 release.
2529 README, WHATS.NEW: Update for 3.92.6 release.
2531 tconfig/{altos, i386v, i386v32, m88k, umax}: Eliminate
2532 coffread.o from configs since it is now built by default.
2533 tconfig/{3b1, altosgas, arm, convex, hp300bsd, hp300hpux,
2534 i386v-g, i386v32-g, isi, merlin, news, news1000, np1, pn,
2535 pyramid, symmetry, vax, vxworks68}: Eliminate dbxread.o
2536 from configs since it is now built by default.
2538 Makefile.dist: Update for release 3.92.6. Handle files that
2539 have been moved to ../include, ../getopt, or ../bfd. Add
2540 saber.suppress and tests directory. Add config.status to
2541 the release (it will say "none").
2543 coredep.c: Minor formatting fixes.
2545 These changes were made in early December but only checked in now:
2546 * nindy-share/Onindy.c, nindy-share/coffstrip.c,
2547 nindy-share/nindy.c: lint
2548 * nindy-share/nindy.c (ninStopWhy): Don't byteswap the
2549 register values coming back from the target; we store values
2550 in target byte order everywhere.
2552 Wed Jan 16 19:01:37 1991 John Gilmore (gnu at cygint.cygnus.com)
2554 * am29k-opcode.h, am29k-pinsn.c: Add 29050 opcodes.
2556 * valprint.c (cplus_val_print, val_print_fields): New functions,
2557 which print C++ objects. They conspire to avoid printing a
2558 virtual base class more than once, following all the twists and
2559 turns of C++ virtual base rules.
2560 (val_print): Call the above rather than do it by hand.
2562 * symfile.c (symbol_file_add): Only reset symfile_mtime for main
2563 symbol file, not for added files like shared libs. This really
2564 needs to be generalized to a timestamp per file.
2566 * core.c (cleanup_core): Avoid coredump if no core file.
2568 * config.gdb: Accept -host or -target in place of +host or
2571 * coffread.c (find_linenos): Avoid desupported BFD interface
2572 to line numbers. We still read them manually rather than using
2573 BFD's "generic" features.
2575 * gdbrc.tex, threecol.tex: Add GDB reference card and its
2577 Makefile.dist: Add refcard to OTHERS list for creating tar files.
2579 * Makefile.dist: Eliminate use of $< in explicit targets.
2581 * readline/Makefile: Use $< rather than $*.c, which does not
2582 include the VPATH in GNU Make.
2584 * tconfig/i960-bout, tconfig/i960-coff: These are identical
2585 copies of tconfig/i960, added for global configuration
2586 compatability. All i960 versions can read both coff and b.out.
2588 * tm-88k.h: Fix multiline macro that lacked \'s. Remove
2589 COFF_FORMAT and COFF_CHECK_X_ZEROES since these are now handled
2592 * TODO: Think of more things to do.
2594 Wed Jan 2 19:09:29 1991 John Gilmore (gnu at spiff.cygnus.com)
2596 tconfig/{am29k,i960,sun2*,sun3*,sun4*}: Eliminate config
2597 of sdb versus dbx debug symbols. Add kludge for 68881 80-bit to
2598 64-bit float conversion.
2600 tconfig/sun4, tconfig/sun3, xconfig/sun4, xconfig/sun3: Make
2601 equivalent to sun?os4 so global config works.
2603 Wed Jan 2 18:20:51 1991 John Gilmore (gnu at spiff.cygnus.com)
2605 Fix from Eberhard Mattes <mattes@azu.informatik.uni-stuttgart.de>
2607 * main.c: Only declare linesize once; declare pagesize not at
2608 all, since it is never used.
2609 (main): Clear newly allocated line before it is used.
2611 Fri Dec 28 00:13:42 1990 John Gilmore (gnu at cygint)
2613 Further stabilization for the Intel 960.
2615 * Makefile.dist: Parameterize the location of the "include"
2616 and "bfd" directories, as well as "getopt". Add symfile.c.
2617 Link in both dbxread and coffread. Fix up "make depend" to
2618 rewack the locations of include, bfd, and getopt in its output.
2620 * README: Document moving include files, improve some of
2623 * coffread.c: Move common code out to symfile.c. Change
2624 symbol_file_command style interface to use new *_symfile_init
2625 and *_symfile_read interface under BFD. Use BFD internal
2626 info to locate line table, symbols, etc.
2628 * core.c (core_fetch_registers): Rename to get_core_registers
2629 to avoid confusion with fetch_core_registers.
2630 (register_addr): Move to coredep.c, which is already machine
2631 dependent. This leaves core.c pretty clean of dependencies.
2633 * coredep.c (register_addr): Accept this routine from core.c.
2635 * dbxread.c: Move common code (with coffread.c, etc) into new
2636 symfile.c. Each psymtab now contains a pointer to the
2637 format-dependent function that knows how to read it in. Make
2639 (dbx_psymtab_to_symtab): Renamed from psymtab_to_symtab_2.
2640 (process_one_symbol): Add code to complain about a "compiler bug
2641 we muzzle here", if we actually see it.
2643 * eval.c (evaluate_subexp): Insert missing "break" statements
2644 in code that determines whether a variable is an lvalue in
2645 memory, register, or whatever. I detected this via a compiler
2646 bug in which it *almost* mashed out the whole switch statement.
2648 * gdb-int.texinfo: Add minor sections on configuring gdb for
2649 release, and about the README file.
2651 * infcmd.c (registers_info): Fix formatting somewhat. Still
2652 not as pretty as before, but it handles byte swapping.
2654 * remote-nindy.c: If data cache routines are interrupted while
2655 waiting for the remote end, be sure that any uninitialized cache
2656 blocks are on the free list, not on the valid list!
2658 * symfile.h: Flesh out this header file with all the various
2659 routines and variables that have been merged in from dbxread.c
2660 coffread.c, and symtab.c to symfile.c.
2662 * symfile.c: New file, containing code common to dbxread.c,
2663 coffread.c, and some code from symtab.c. All generic code for
2664 reading symbol files should be in here now.
2665 (unrecord_misc_function): Remove unused function.
2667 * symtab.h: Remove file-reading things to symfile.h.
2669 * symtab.c: Remove file-reading things to symfile.c.
2671 * tm-i960.h: Fix FRAME_CHAIN types; define PRINT_RANDOM_SIGNAL
2672 to decode i960 fault types.
2674 * target.h, remote.c, remote-eb.c, remote-vx.c, remote-nindy.c,
2675 target.c: Change type of the "resume" function from int to void,
2676 since its result was never used.
2678 Sat Dec 22 02:51:40 1990 John Gilmore (gnu at cygint)
2680 * main.c: Replace "stupid" with "caution"; you now "set caution
2683 * printcmd.c (print_scalar_formatted): Fix typo in 'g' format
2685 * infcmd.c (do_registers_info): Call val_print to deal with the
2686 byte order of the registers being printed. FIXME, this makes
2687 the formatting of the output uglier.
2689 * infcmd.c (wait_for_inferior): If PRINT_RANDOM_SIGNAL is
2690 defined, call it for signals the debugger doesn't itself use.
2691 The i960 uses this for more detailed fault information.
2693 * remote.c (remote_open): If arg is null, print help rather than
2696 * sparc-xdep.c (register_valid): Avoid declaring size, since
2697 various modules will think of various sizes depending on the
2698 architecture of their tm-file. FIXME, we need protection against
2699 actually entering one of those modules, which would clobber
2700 storage if not for the target architecture compiled into gdb.
2702 * stack.c (up_command, down_command): Always print the frame
2704 (up_silently_command, down_silently_command): New commands
2707 * i960-pinsn.c (reg), i960-tdep.c: Lint.
2709 * i960-tdep.c (i960_frame_chain_valid): Lookup_symbol now takes
2710 more parameters than it used to.
2712 * findvar.c (registers): Increase slop to 256 bytes, which should
2713 protect us against even most RISC machines with large register
2715 (locate_var_value): Move declaration inside related ifdef.
2717 * remote-nindy.c (): Use TIOCSETN rather than TIOCSETP
2718 throughout, to avoid throwing away buffered input from the board.
2719 (nindy_wait): Supply_register takes addr_of_value, not value.
2720 (i960_print_fault): Renamed from i80960_fault.
2721 (nindy_fetch_registers): Avoid have_regs stuff, just get them.
2722 (nindy_store_registers): Avoid regs_changed stuff, just stuff
2724 (nindy_create_inferior): Don't bother to write PC_REGNUM since
2725 we can set the PC in the call to proceed(). Unpush nindy_ops
2726 before pushing it on top, to avoid message to user. Eliminate
2727 commentary from Unix machines that just misleads here.
2728 (reset_command): Fix error message to suggest target command.
2730 Wed Dec 19 11:03:56 1990 John Gilmore (gnu at cygint)
2732 Release 3.92.5 as frozen.
2734 Stabilize the merged release...with help from lint, Saber C,
2737 Everywhere: Add include files needed to declare return types
2738 of functions called.
2740 * gdb.texinfo: Roland Pesch is documenting gdb, glory be!
2742 * breakpoint.h: Add undeclared breakpoint functions, and some
2743 functions for display handling since I couldn't think of a better
2746 * breakpoint.c (insert_breakpoints): Make code for disabling
2747 shared library bkpts more likely to work. It's used when we
2748 rerun a program and stop before the shared library has been
2750 (breakpoint_cond_eval, bpstat_stop_status): Pass arg as int,
2751 cast from pointer, so it squeezes through catch_errors.
2752 (bpstat_stop_status): Fix logic broken some time ago. We now
2753 always create a bpstat if the stop address matches a breakpoint,
2754 even if we don't stop there -- just like the old code used to do
2755 before I got my fingers into it (sigh).
2756 (breakpoint_1): Print "ignore count" after "stop only if"
2757 condition, since that's how it actually works.
2758 (mention): Handle watchpoints as well as breakpoints.
2759 (watch_command): use set_raw_breakpoint and mention to do most
2760 of the work (and initialize all the fields!). Only pass one
2761 arg to parse_c_expression, since that's all it takes.
2763 * command.c (not_just_help_class_command): Rename arg to args
2764 since we ignore "unused argument" warnings on vars named "args".
2765 inflow.c (child_terminal_info): ditto.
2766 infptrace.c (kill_inferior): ditto
2767 main.c (catch_errors, version_info, quit_command, pwd_command,
2768 source_command, dump_me_command, editing_info,
2769 set_history_size_command, set_history, show_history,
2771 stack.c (locals_info): ditto
2772 target.c (target_files_info): ditto
2773 valprint.c (set_input_radix, set_output_radix): ditto
2775 * core.c: Remove old variables for handling core and exec file
2776 sections (data_start, data_end, stack_start, stack_end,
2777 reg_stack_start, reg_stack_end, reg_stack_offset, text_start,
2778 text_end, exec_data_start, exec_data_end, text_offset,
2779 exec_data_offset, data_offset, stack_offset). They're
2780 superseded the more general build_section_table and
2782 (get_exec_file): Mention the `file' command.
2783 (read_memory_check): Rename to memory_error, and only call it
2784 in the case of an actual error.
2785 (read_memory, write_memory): call memory_error.
2786 (core_fetch_registers): Register section name is ".reg".
2788 coredep.c: Remove a bunch of crud now that all this file does
2789 is pull the registers out of a core file.
2790 (fetch_core_registers): Rewrite to actually work, I hope.
2792 dbxread.c: Use a.out.gnu.h, not system a.out, now.
2793 Replace index() with strchr(). Remove all the pre-BFD macro
2794 definitions for accessing the symbol file.
2795 (struct dbx_symfile_info): Encapsulate the information that
2796 dbx_symfile_init needs to pass to dbx_symfile_read in this
2799 (dbx_new_init, dbx_symfile_init, dbx_symfile_read,
2800 dbx_symfile_discard): Rearrange symbol file reading to divide
2801 the format-specific part from the format-independent part,
2802 leaving the format-independent part such as file name expansion
2803 and opening in symtab.c. This replaces
2804 partial_symbol_file_open and partial_symbol_file_read.
2805 Symbol_file_read, add_file, add_file_target_command,
2806 add_file_addr_command move to symtab.c. Pass an explicit
2807 "mainline" flag for when reading the main symbol table, rather
2808 than relying on the offset address to be zero or nonzero.
2810 (dbx_symfile_read): Don't allow void *'s to be printed as
2812 (SWAP_SYMBOL): Use bfd routines to byte-swap the symbols.
2813 (ADD_PSYMBOL_TO_LIST): Make the "function call rather than
2814 macro" debug version really work.
2815 (read_dbx_symtab): Remove unref'd parameter inclink.
2816 Avoid swapping N_SLINE symbols, for speed.
2817 Merge N_TEXT!N_EXT case with the other external symbol
2818 definitions' case. Add comments.
2819 (start_psymtab): Allocate the symfile name in the psymtab on
2820 the psymbol_obstack, rather than using the caller's storage.
2821 (end_psymtab): Only allocate a dependencies list if there are
2823 (psymtab_to_symtab_2): Use BFD when reopening file to read
2824 its symbols for real.
2825 (read_struct_type): Add FIXME comments where it needs work
2827 (read_huge_number): Add FIXME about overflows.
2828 (read_range_type): Add FIXME about comparing a long to 1<<32.
2830 * coffread.c: Minor changes to move things closer to the new
2831 regime with symtab.c and dbxread.c Major work is still needed
2834 * exec.c (exec_file_command): Remove old variables (see core.c
2836 (xfer_memory): If memory transfer is right at the end of a
2837 section, don't lose.
2839 * findvar.c (get_saved_register): If value is in a real
2840 register, LVAL is lval_register, not lval_memory.
2842 frame.h: Declare print_sel_frame and record_selected_frame.
2844 gdb-int.texinfo: New file, for GDB internals documentation.
2845 Very simple, unformatted doc of cleanups is there for now.
2847 gdbcore.h: Remove obsolete variables that described a.out
2848 section addresses and offsets. (See core.c above.)
2849 Declare fetch_core_registers and registers_fetched.
2851 getopt.c: Declare char *alloca(); even on SPARC.
2853 infcmd.c (run_command): Call target_kill rather than
2855 (step_command, next_command, stepi_command, nexti_command):
2856 Declare from_tty parameter even though we don't use it.
2857 (run_stack_dummy): argument BUFFER is a char array, not
2858 a pointer to REGISTER_TYPE.
2859 (finish_command): using_struct_return needed a value *,
2860 not a struct symbol *.
2862 * infptrace.c (child_xfer_memory): To avoid dependency on
2863 where sections are in memory, try PT_WRITE_D and if that fails,
2864 try PT_WRITE_I. Most Unixes don't care which you use.
2866 * infrun.c (step_resume_break_shadow): Change to array to
2867 match other breakpoint shadow storage.
2868 (clear_proceed_status): Pass address of bpstat to
2869 bpstat_clear, not the bpstat itself.
2870 (child_create_inferior): FIXME comment about if the child
2872 (start_inferior): Remove old function.
2873 (child_open): Use target_kill rather than kill_inferior.
2874 (wait_for_inferior): Ditto.
2875 (insert_step_breakpoint, remote_step_breakpoint): Use
2876 new step_resume_break_shadow.
2878 * inftarg.c (child_wait): If all child processes die,
2879 pretend that the one being waited for exited with signal 42.
2881 * main.c (command_line_input): When scanning for comments,
2882 don't coredump on unclosed quotes.
2883 (quit_command): Use target_kill rther than kill_inferior.
2884 (_initialize_main): Rename class_user from "user" to
2887 * printcmd.c (print_command_1): Initialize "fmt" if no format
2888 is specified by the user.
2889 (print_frame_args): Only add to args_printed if we are
2890 actually fetching args from the stack (avoiding undefined
2892 (_initialize_printcmd): Remove bogus \{ from string.
2894 * remote-eb.c (eb_open): Avoid coredump on no argument.
2896 * remote-nindy.c: Bring out of Intel environment into new
2897 target environment. Remove all conditional compilation on
2898 I80960. Massive hacking throughout.
2899 (nindy_xfer_inferior_memory): New routine stolen from
2901 (nindy_create_inferior): New routine pieced together, probably
2902 not quite working yet.
2903 (nindy_ops): New target_ops struct for nindy.
2905 * remote-vx.c: Use write_memory rather than target_write_memory
2906 to get error checking.
2907 (vx_add_file_command, vx_open): Use symbol_file_add rather than
2909 (vx_create_inferior): Use target_terminal_ours...
2911 * signame.c (_initialize_signame): Always initialize, since
2912 we need the table for things other than psignal.
2914 * solib.c (solib_add): Use symbol_file_add, not add_file.
2915 (solib_address): Return boolean result rather than struct
2916 pointer which nobody else knows the type of.
2918 * sparc-tdep.c, valops.c: Use write_memory rather than
2919 target_write_memory, to get error checking.
2921 * stack.c (locals_info, catch_info, args_info,
2922 get_selected_block, frame_command, up_command): Use
2923 target_has_stack, rather than have_inferior_p or
2926 * sun3-xdep.c (fetch_core_registers): Rewrite for new BFD regime.
2928 * symfile.h: New file, defining the interface between the
2929 generic and object-file-specific symbol reading code.
2931 * symtab.c: Move generic symbol-reading interface to symtab.c,
2932 from dbxread.c, coffread.c, mipsread.c, etc. Add symtab_fns
2933 table to map BFD targets to symbol-reading modules in GDB.
2934 Change index to strchr.
2935 (lookup_struct_elt_type): Use error() rather than hand-made
2936 simulations thereof.
2937 (lookup_partial_symbol): Speedup slightly when length == 0.
2938 (symbol_file_add): New function.
2939 (symbol_file_command): Call it.
2940 (symfile_open, symfile_init): New function.
2941 (add_file_target_command, add_file_addr_command): moved from
2944 * target.c (target_command): use target_kill.
2946 * target.h (target_files_info): Don't declare, never called
2949 * tm-sun2.h, tm-sun3.h (STACK_END_ADDR): Use system include
2950 files to determine stack end address.
2952 * valarith.c (value_x_binop, value_x_unop): Change error message
2953 to be more useful. Pass proper argument to value_struct_elt.
2955 * valops.c (value_assign): FIXME comment that long long
2956 bitfields will break here.
2958 * Makefile.dist: Add symfile.h, remote-nindy.c, remote-eb.c.
2959 Update `make saber_gdb' to work better.
2961 * TODO: A woman's work is never done.
2963 * cplus-dem.c, environ.c, inferior.h, infrun.c, inftarg.c,
2964 main.c, obstack.c, printcmd.c, remote-eb.c, remote-nindy.c,
2965 remote-vx.c, remote.c, solib.c, source.c, sparc-pinsn.c,
2966 sparc-tdep.c, sparc-xdep.c, symmisc.c, symtab.c, symtab.h
2967 target.c, terminal.h, tm-sparc.h, tm-sunos.h, utils.c,
2968 valops.c, valprint.c, exec.c: Lint.
2971 Wed Dec 12 23:44:15 1990 John Gilmore (gnu at cygnus.com)
2973 Continuing Intel 960 port merge of GDB.
2975 * Makefile.dist: Merge i960 "nindy-share" files. Rename
2976 malloc.h to gmalloc.h to avoid name conflicts in /usr/include.
2977 Don't ship gdb.dvi in tar file. Link gdb with init.o, not init.c.
2978 Wack over "make depend" so it handles files in subdirectories
2979 vx-share, nindy-share, bfd, and in the current directory.
2981 * blockframe.c (get_prev_frame_info): Remove fatal error
2982 if stack not defined.
2984 * core.c (core_open, core_detach): New functions that handle
2985 the old "core-file" command as "target core" and "detach" instead.
2986 (core_file_command): Call them.
2987 (core_xfer_memory): Use common routine xfer_memory.
2989 * dbxread.c: Include a.out.gnu.h, not system a.out.h.
2990 dbxread now uses bfd for everything but symbol reading itself.
2991 BFD internals are used to drag out the relevant file offsets.
2992 (partial_symbol_file_open): Change args all around for BFD.
2994 * symtab.c: Rename "value" to "val" everywhere, so we can
2996 (symbol_file_command): New command, moved from dbxread.c
2997 and coffread.c. It uses BFD to read the file, then vectors
2998 based on its type, to dbx or coff symbol readers.
2999 * symtab.h: Extern a few vars for symbol_file_command.
3001 * target.h: Breakpoint takes a char * save area, not a char **.
3003 * valprint.c (val_print): When unpacking bitfields, offset
3004 the address in gdb of the value, if it is declared with a shorter
3005 type. Remove the last "runtime kludge test" of host byte order.
3007 * utils.c: Remove old my_bfd_read routine.
3009 * stack.c (frame_info): Use target_has_stack. Print program counter
3010 register's actual name rather than "pc", since it's called the
3011 "ip" (instruction pointer) on the i960 (sigh).
3013 * target.c (target_command): Add command for selecting a target
3014 type and calling its open routine. This is used for initiating
3015 communication with a particular target, in a generic way.
3017 * tm-i960.h: Update for modern gdb. Remove semicolons from
3018 various macros. Handle reading struct return convention, and
3019 error-out attempts to return structs with the "return" command.
3020 Be sure gdb doesn't think we know how to call functions in the
3023 * i960-tdep.c: Rename FRAME_CHAIN_VALID and FRAME_FIND_SAVED_REGS
3024 to i960_xxx in lower case.
3025 (arg_address): Circumvent errors due to LOC_ARG_BLOCK
3026 not being defined yet.
3028 * remote.c (remote_open): Call start_remote to initialize
3029 wait_for_inferior during open.
3030 (remote_xfer_inferior_memory): Return length written rather
3033 * remote-vx.c (target_command -> vx_open): Use new generic
3035 * remote-eb.c, inftarg.c, exec.c: ditto.
3037 * infrun.c: Fix comments.
3038 (attach_program -> child_open): Use new generic target command.
3039 (wait_for_inferior): Clear saved register values before target_wait,
3040 so target_wait can set some of them if convenient.
3042 * infptrace.c (fetch_inferior_registers, store_inferior_registers):
3043 Return success indicator, not void.
3044 (child_xfer_memory): Avoid fetching initial word if we'll
3045 overwrite it anyway.
3047 * infcmd.c (attach_command): Use new generic target open routine.
3048 (_initialize_infcmd): Update doc on attach and detach commands.
3049 (do_registers_info): Merge in a byte-order problem as a FIXME
3052 * findvar.c (find_saved_register): Avoid problem in current frame.
3053 (read_relative_register): Ditto.
3054 (write_register): Convert byte order on the way out.
3056 * exec.c (file_command): Add.
3057 (add_to_section_table, exec_command): Use new bfd_map_over_sections.
3058 (xfer_memory): Common function between core_xfer_memory and
3060 (exec_xfer_memory): Use it.
3062 * pn-opcode.h: Document that a "PN" is a Gould PowerNode.
3064 * breakpoint.c, breakpoint.h, symtab.h, value.h, frame.h, utils.c,
3065 valops.c, stack.c, target.c, sparc-xdep.c, source.c, printcmd.c,
3066 infcmd.c, i960-pinsn.c, eval.c, defs.h: lint and gcc -Wall.
3068 Sun Dec 2 16:45:06 1990 John Gilmore (gnu at cygnus.com)
3070 Merge Intel 960 port of gdb, continuing...
3072 * dbxread.c (partial_symbol_file_open, partial_symbol_file_read,
3073 symbol_file_command): Pass from_tty arg to hush 'em up.
3075 * coffread.c (symbol_file_command): Avoid output if from_tty != 1.
3076 Add magic numbers for 960 COFF format.
3078 Fri Nov 30 09:18:20 1990 John Gilmore (gnu at cygnus.com)
3080 Merge Intel 960 port of gdb, from Intel "1.2" release.
3082 CHANGE_LOG entries from their port, which was based on
3085 Thu Sep 6 11:02:22 PDT 1990
3086 Remove temp file if download is interrupted.
3088 Wed Aug 1 09:08:33 PDT 1990
3089 Now uses binary protocol to talk to NINDY.
3090 Old hex protocol (NINDY 2.13 and older) supported with -O switch.
3091 Times out after 5 seconds when trying to talk to NINDY.
3093 Tue May 29 12:54:49 PDT 1990
3094 Added variable baud rate (-b switch).
3095 Source code reorganization.
3097 Thu Apr 26 11:09:55 PDT 1990
3098 More cleanup of batch mode; specifically, execute "-s", "-e", and
3099 "-se" switches as soon as they are encountered on the invocation line.
3101 Fri Apr 20 13:47:15 PDT 1990
3104 Thu Apr 19 09:54:28 PDT 1990
3105 Add 'reset' command.
3107 Wed Apr 18 09:48:07 PDT 1990
3108 After opening remote tty, wait for 1 second to go by without input
3109 from it before trying to talk to NINDY (fixes problems with the
3110 Heurikon HK80/V960E).
3112 Mon Apr 4 16:33:05 PDT 1990
3113 Some output was not being suppressed in 'batch' mode.
3115 Thu Mar 22 15:31:11 PST 1990
3116 Ask user if old symbol table should be deleted when new file is
3119 Allow user to run a program downloaded before gdb960 was brought up.
3121 Correct "exec-file" help message for i80960 context.
3123 Correct bug in calculating user space address: could occasionally
3124 corrupt user program.
3126 Make sure to zero low-order bits in rip's because of bug in 960CA
3127 A-step part: could cause operation faults when "next"ing across
3130 Correct bug that made it impossible to get source line numbers for
3131 code loaded at addresses higher than 0x7fffffff.
3133 Wed Jan 10 12:43:22 PST 1990
3134 Open remote tty for exclusive use.
3136 Fri Jan 5 12:14:42 PST 1990
3137 Correct disassembly (CA manual was right after all):
3138 opcode for sysctl is 0x659
3140 Mon Oct 23 12:03:04 PDT 1989
3141 Use G960BASE and G960BIN environment variables to find 'sx' utility.
3143 Mon Oct 16 14:15:09 PDT 1989
3144 "sfr0"-"sfr31" should have been named "sf0"-"sf31"
3146 Mon Oct 2 15:56:31 PDT 1989
3148 Added 960CA disassembly support.
3150 To simplify maintenance:
3151 - eliminated use of symblic links on pinsn.c: use i960-pinsn.c
3153 - eliminated opcode.h: incorporates tables into i960-pinsn.c
3154 - moved 960-specific routines from i960-pinsn.c to i960-md.c
3155 - made disassembly interface identical to that in gdmp960.
3159 Wed Nov 28 21:32:48 1990 John Gilmore (gnu at cygint)
3161 * target.h: Allow targets to stack. Add target_has_memory,
3162 _registers, etc. Restructure memory access and "info files"
3163 to walk the target stack.
3164 * exec.c, core.c, inftarg.c, remote.c, remote-vx.c, remote-eb.c,
3165 target.c: Change tables to match target.h.
3166 * inflow.c (child_mourn_inferior): pop child_ops.
3167 (generic_mourn_inferior): Use new has_stack flag.
3168 * infptrace.c (child_xfer_memory): New memory regime.
3169 * inftarg.c (child_files_info): New "info files" regime.
3170 * remote-eb.c: New memory regime, new info files.
3171 * remote-vx.c: New memory regime, new info files. Now use
3172 separate targets for VxWorks attachment to machine, and
3173 actually running a process under VxWorks, since one has
3174 stack & execution & regs and the other doesn't.
3175 * remote.c: New memory regime, new info files.
3176 * sparc-xdep.c (fetch_core-registers): New memory regime.
3177 * target.c: New routines and support for stacked targets,
3178 new memory regime, new info files regime.
3181 Generalize section handling for an arbitrary number of sections,
3182 including use of the new BFD (binary file) library.
3183 * gdbcore.h: Add struct section_table.
3184 * exec.c (build_section_table): Iterate all sections and
3185 record what gdb needs to know about them.
3186 (exec_command): Use it.
3187 (exec_xfer_memory): Use the table.
3188 (exec_files_info): Print the table.
3189 * core.c (core_file_command, core_xfer_memory, core_files_info):
3191 * source.c (find_source_lines): Use bfd_get_mtime.
3192 * dbxread.c: Quick changes to make it compile with new BFD.
3193 * utils.c (error): Avoid using bfd_error in generic routines.
3195 * core.c (core_fetch_registers): Get from the ".regs" section of
3197 * sparc-xdep.c (fetch_core_registers): Use the .regs info.
3199 * inferior.h (attach_flag): Export.
3200 * infcmd.c (run_command): use new target_create_inferior.
3201 * infrun.c (child_create_inferior): Don't return result.
3202 * Makefile.dist (VERSION): 3.91.4.
3204 Fri Nov 23 28:15:38 1990 John Gilmore (gnu at cygint)
3206 * breakpoint.c (bpstat_num): Handle breakpoints which have
3207 since been deleted, such as temporary breakpoints.
3208 infcmd.c (program_info): ditto.
3210 * core.c (core_file_command): Display the frame where the core
3215 * remote-vx.c (target_command): Merge in target command from
3216 targ-vx.c. A few other cleanups.
3218 * TODO, Projects: Lots more stuff to do...
3220 Fri Nov 23 18:15:38 1990 John Gilmore (gnu at cygint)
3222 Massive changes to wall off the remote-debugging interface
3223 behind a function vector. The port to handle VxWorks targets
3224 is also part of this.
3226 All files: Replace references to renamed functions,
3227 remove references to remote_debugging, remove references to
3228 have_include_file, have_core_file in favor of target_has_stack,
3229 target_has_memory, etc.
3231 * Modularize the breakpoint interface.
3232 breakpoint.h (BREAKPOINT_MAX): New define sets max length of
3233 a breakpoint instruction.
3234 breakpoint.c: struct breakpoint's shadow_contents now sized as
3236 (insert_breakpoints): Vector to target to install breakpoints.
3237 (remove_breakpoints): Vector to target here too.
3238 Remove REMOTE_SA_SPARC kludges and other remote_debugging.
3239 sparc-tdep.c (single_step): Use new breakpoint interface for
3240 the single-step breakpoints.
3241 mem-break.c (memory_insert_breakpoint, memory_remove_breakpoint):
3242 New file, contains routines to insert and remove breakpoints by
3243 reading out the old contents and later replacing them. This is
3244 how ptrace breakpoints work, and many remote systems as well.
3246 * tm-vxworks68.h: New config file, overrides a few things for
3247 Wind River's preferences.
3249 * target.h: New file, for transfer vector used to talk to the
3250 inferior (child, attached, core, exec, remote, etc). All accesses
3251 to the thing being debugged should come through these vectors.
3252 target.c: New file, routines to handle transfer vector.
3253 (various files): Add transfer vectors XXX_ops for the various
3254 targets and pseudo-targets (core files, etc) we support.
3256 * breakpoint.c (bpstat_stop_status): Further explorations of
3257 watchpoints and why things don't work all the time.
3258 (bpstat_alloc): New fn to allocate a bpstat and chain it.
3260 * config.gdb: Only add "source ${srcdir}/.gdbinit" to
3261 the local gdbinit if it doesn't already have it.
3263 * core.c (core_ops): add and install.
3264 Allow core debugging without exec file.
3266 * dbxread.c (free_and_init_header_files): Merge two fns.
3267 (end_symtab): Free named symbol table when a new version comes in.
3268 (read_dbx_symtab): Relocate all kinds of symbols with base
3269 address. First step toward handling different text, data, bss
3271 (add_file_addr_command): Renamed add_file_command.
3272 (add_file_command): Vector to remote handler.
3273 Add "load" as an alias for "add-file" command.
3275 * defs.h: Allow "volatile" to be used in non-ANSI; use it for
3276 non-returning functions.
3278 * exec.c: Add exec_ops, and push it as a target when an exec
3281 * infcmd.c (run_command): Pass executable file name and arg list
3282 separately when starting an inferior. Permit "run" when no exec
3283 file is specified, for VxWorks.
3284 (detach_command): Move to child_detach in inftarg.c.
3286 * inftarg.c: New file. Unix-child-specific routines, and the
3287 child_ops structure.
3289 * inferior.h (registers): Export "registers" as the way for
3290 target dependent register handlers to find gdb's local copy of
3291 the registers. Rename "stop_after_attach" to "stop_soon_quietly"
3292 since it is now used by places that want wait_for_inferior to
3293 handle the grunge but want to see every trap from the inferior.
3295 * inflow.c (create_inferior): Pull out, and merge into infrun.c.
3296 Eliminate remote_debugging hooks in terminal handling.
3298 * infrun.c: Replace start_inferior with child_create_inferior.
3299 Move all the hair of Unix shells and ptrace idiosyncracies into
3300 child_create_inferior, so remote handlers don't have to deal.
3301 Remove running_in_shell. Rename stop_after_attach to
3302 stop_soon_quietly, and use it in a few other places where we want
3303 to just call wait_for_inferior and get control back on the first
3304 trap. trap_expected now never takes a value > 1.
3305 (init_wait_for_inferior): Initialize static vars when a new
3308 main.c (gdbinit): Add new hook for .gdbinit file name, let
3309 it be overridden by config files as GDBINIT_FILENAME.
3310 (DEFAULT_PROMPT): Add new hook for overriding (gdb) prompt.
3311 Both of these are used for VxWorks gdb.
3313 mcheck.c: rename include file "gmalloc.c" to avoid problems
3314 with system include file "malloc.c".
3316 param-no-tm.h: New include file, same as param.h but does not
3317 include the default "tm.h" file. This is used in files where
3318 the target is known, e.g. remote-eb.c or sparc-xdep.c.
3320 param.h: Now just a shell that includes tm.h and param-no-tm.h.
3322 remote-vx.c: New file, VxWorks remote debugging support. Uses
3323 RPC routines that are shared with the target system, in directory
3326 remote.c: Vectorize remote interface.
3328 source.c: Globalize source_path, and make an alias "l" for "list"
3329 since we now have the "load" command.
3331 sparc-xdep.c: Use new param-no-tm.h.
3333 symmisc.c (free_named_symtab): Add new function from Wind River.
3334 However, ifdef it out for now while we think about what it should
3337 tm-sun3.h, xm-sparc.h, xm-sun3.h, xm-symmetry.h: Move
3339 the xm- file, and change its name to CHILD_PREPARE_TO_STORE, since
3340 non-Unix-children handle this with their own code in the target
3343 Makefile.dist: Roll version to 3.92.3. Add vx-share stuff to
3344 source and target lists. Add vx-share to default list of include
3345 directories. Add new files to src and target lists: mem-break,
3346 target, inftarg, remote-eb, remote-vx, targ-vx. Be sure the
3347 ${srcdir} versions of munch and createtags are used.
3349 * valops.c (find_function_addr): Split out of call_function.
3350 (call_function_by_hand): Rename call_function; this function
3351 calls functions in the target by laboriously patching the target
3352 word-by-word with the right stack, args, regs, etc.
3355 Mon Nov 5 17:29:10 1990 John Gilmore (gnu at cygint)
3357 Handle AMD 29000 a bit better.
3359 * remote-eb.c (readchar): Mask received char log to make it readable.
3360 (remote_start): Pass arguments down to executing program.
3361 Make startaddr unsigned.
3362 infrun.c (start_inferior): Accept args, pass them to
3364 infcmd.c (run_command): Pass args down to start_inferior.
3366 * tconfig/am29k-aout, tconfig/am29k-coff: New files specifying
3367 the target object file format.
3368 tm-29k.h: Pay heed to COFF_ENCAPSULATE.
3370 * am29k-pinsn.c (print_insn): Print 0x on hex numbers in disassembly.
3371 am29k-tdep.c (examine_prologue): Better checking of function prefixes.
3373 Sun Oct 7 18:20:45 1990 John Gilmore (gnu at cygint)
3375 * Makefile.dist (VERSION): Roll version to 3.91.9 and freeze.
3376 * TODO: We did a few things, we have more to do though.
3378 * xm-sparc.h (CLEAR_DEFERRED_STORES): Define.
3379 * inflow.c (inferior_died): Clear deferred stores.
3381 * Debug problems with dummy frames and calls to the inferior.
3382 * tm-sparc.h (PUSH_DUMMY_FRAME, POP_FRAME): Move to sparc-tdep.c.
3383 * sparc-tdep.c (do_restore_insn): Simplify.
3384 (sparc_frame_find_saved_regs): Simplify and fix what we find.
3385 (sparc_push_dummy_frame): Simplify and fix what we push.
3386 (sparc_pop_frame): Slightly more hair here, deciding whether
3387 we are restoring a saved PC or returning to a return address in %i7.
3388 * sparc-xdep.c (read_inferior_registers): Debug if valid reg is read.
3390 * utils.c (xmalloc, xrealloc): Return type depends on __STDC__.
3391 * symtab.h (xmalloc): ditto, for obstack_chunk_alloc.
3392 * obstack.h (chunkfun): ditto.
3393 * defs.h (xmalloc, xrealloc): ditto
3395 * utils.c (quit): Grab the terminal from the child if necessary.
3397 * inflow.c (term_status_command): Rename to term_info, change
3400 * sparc-pinsn.c (print_insn): Disassembly prefers real instructions.
3401 (is_delayed_branch): Speed up.
3402 * sparc-opcode.h: Add ALIAS bit to aliases. Fix up opcode tables.
3403 Still missing some float ops, and needs testing.
3405 * Support for input and output radixes other than base 10
3406 * defs.h (input_radix, output_radix): Declare.
3407 * expread.y (yyparse, parse_number): Handle changes of input
3408 radix, and ambiguous names-or-numbers in radixes >10.
3409 * printcmd.c (print_scalar_formatted): Print formatted hex
3410 numbers in varying column widths.
3411 * valprint.c (val_print): Use output_format to print scalar ints.
3412 (set_input_radix, set_output_radix, set_radix): Create.
3413 (set_output_radix): Set output_format from output_radix.
3414 (_initialize_valprint): add `set radix' but leave the others off.
3416 * main.c (execute_command): Let stupid questions be turned off.
3417 (_initialize_main): Handle "set stupidity", etc.
3419 * main.c, inflow.c, inferior.h, frame.h, command.c, defs.h,
3420 sparc-pinsn.c, sparc-xdep.c, value.h, valops.c, values.c: Lint.
3422 Tue Oct 2 11:20:02 1990 John Gilmore (gnu at cygint)
3424 * TODO, Makefile.dist, ChangeLog: Freeze for 3.91.8 release.
3425 bfd stuff is still screwed up, but with some manual work, it
3428 * breakpoint.c (bpstat_do_actions): Start over if a command
3429 proceeds the inferior, since the inferior will have stopped and
3430 will need to have its new stop-actions taken care of.
3432 * dbxread.c (read_struct_type): Expression gives Sun3 4.0.3
3433 compiler fits, simplify it.
3435 * gdb.texinfo (directory command): Doc new dir command.
3436 source.c (directory_command): "dir" now puts things on the front
3437 of the path, moves dups up front, and handles multiple names
3438 on the command line, inserting each one in order. It also
3439 blows away cached line and full_filename info.
3441 * stack.c (backtrace_command): Skip "more stack frames follow"
3444 * Change #ifndef HAVE_VPRINTF to #define MISSING_VPRINTF in
3445 xm-convex.h, xm-hp300bsd.h, xm-isi.h, xm-merlin.h, xm-news.h,
3446 xm-np1.h, xm-pn.h, xm-pyr.h, xm-symmetry.h, xm-umax.h, xm-vax.h.
3447 The only odd one was Gould NP1, which had defined vprintf to
3450 * Merge Ted Goldstein <tedg@Eng.sun.com>'s changes for epoch.
3451 printcmd.c (print_command_1): Pass 'inspect' flag down as a global
3452 variable, inspect_it.
3453 valprint.c (print_string, val_print): Use the global inspect_it
3454 to indicate whether to print in Epoch style or normal style.
3456 Mon Oct 1 23:55:26 1990 John Gilmore (gnu at cygint)
3458 * printcmd.c (call_command): add an alias for the "print" command
3459 which runs expressions and doesn't print the result if void.
3460 (print_command_1): implement it.
3462 * command.c: Remove #if 0'd code. Initialize all the fields
3463 in add_cmd (). Rename do_nothing_command to
3464 not_just_help_class_command, and make it externally visible.
3465 command.h: add user_commands to struct.
3466 * main.c (define_command): Don't overload c->function with a char
3467 string as well as a function pointer.
3469 * eval.c (evaluate_subexp): Reinstall tiemann changes to
3470 calling convention of value_struct_elt () that got dropped in
3473 * tm-sparc.h (FRAME_FIND_SAVED_REGS): move to sparc-xdep.c.
3474 sparc-tdep.c (sparc_frame_find_saved_regs): ditto.
3476 * tm-sparc.h (POP_FRAME): replace some constants with defines.
3478 * sparc-xdep.c (store_inferior_registers): defer stores to regs
3479 until a good time (e.g. when we are about to run the child),
3480 saving ptrace calls.
3481 * infrun.c (proceed): handle DO_DEFERRED_STORES.
3482 * tm-sparc.h: define DO_DEFERRED_STORES.
3484 * sparc-xdep.c (store_inferior_registers): when storing float
3485 registers, don't store stack regs too. When storing the SP,
3486 however, DO store the stack regs too. This fixes a bug in which
3487 the dummy frame is not recognized when a call_function finishes,
3488 because its frame pointer (in the stack regs) was never
3490 (read_inferior_registers): Mark WIM and TBR and FPS and CPS valid
3491 even though we don't know how to read them from an inferior.
3492 valops.c (call_function): Comment about storing SP.
3494 * infrun.c (save_inferior_status): Save away the original bpstat
3495 chain so it can be restored later. Install the copied version for
3496 use by whoever saved the status. It will be blow away by
3497 restore_inferior_status, and the original chain restored. This is
3498 important for people who have pointers into the original.
3500 * breakpoint.c, command.h, copying.awk, dbxread.c, defs.h,
3501 findvar.c, frame.h, obstack.h, obstack.c, inflow.c, value.h,
3502 main.c, printcmd.c, sparc-tdep.c, symtab.c, valprint.c: lint
3505 Fri Sep 28 20:32:46 1990 John Gilmore (gnu at cygnus.com)
3507 * Makefile.dist: Roll version to 3.91.8. Add bfd.h and bfdconfig.h
3508 temporarily to the makefile. Add am29k-opcode.h and WHATS.NEW.
3509 Add stuff.c and kdb-start.c to the OTHERS list for tar files.
3511 Fri Sep 28 19:12:12 1990 John Gilmore (gnu at cygint)
3513 * Merge Mike Tiemann's multiple inheritance changes from Sun.
3514 Store the baseclasses in a type struct starting from array element
3515 0 rather than from the unusual array element 1.
3517 dbxread.c: the above.
3518 (virtual_context): Add
3519 Read new debug information about which virtual function table
3520 a virtual function is from, and store it in fn_field.fcontext.
3522 symtab.h: Add fcontextt. Fix baseclass indices. Typo in
3523 TYPE_FN_FIELD_STATIC_P.
3525 symtab.c: the above.
3526 valops.c: the above. Handle pointer casts of object *'s.
3527 (search_struct_method): Add.
3528 (value_struct_elt): First arg is now a pointer to a value, and is
3531 valprint.c: the above.
3532 values.c (value_virtual_fn_field): Add type arg. Handle
3533 offsetting to the proper object when calling virtual fns.
3535 (baseclass_addr): Add valuep arg.
3537 * README: Document the current state of BFD config (missing).
3538 * TODO, ChangeLog, Makefile.dist: Roll version.
3539 * WHATS.NEW: Add summary of changes since 3.5.
3541 Thu Sep 27 16:23:12 1990 John Gilmore (gnu at cygint)
3543 * dbxread.c (read_struct_type): Clear bit vectors whenever
3545 symtab.c (B_CLRALL): define.
3547 * tm-sparc.h (STORE_RETURN_VALUE): Avoid clobbering types by
3548 using == rather than =. Huh... This fixes the dreaded problem
3549 wherein builtin_type_int becomes TYPE_CODE_FLT.
3551 * core.c (info_files): Show the inferior pid.
3553 * config.gdb: Avoid putting "dir" command into .gdbinit. GDB
3554 already knows how to look in the source directory.
3556 * Remove psymtab hair from many places. Remove duplicated code
3557 for searching symbol tables. Hide psymtabs from most places.
3558 Make it fast to get from a psymtab to its symtab.
3560 blockframe.c (blockvector_for_pc): Remove psymtab hair.
3561 coffread.c (psymtab_to_symtab): Rename to psymtab_to_symtab2.
3562 mipsread.c (psymtab_to_symtab): Rename to psymtab_to_symtab2.
3563 dbxread.c: export psymtab_to_symtab, make it work if called N times.
3564 (psymtab_to_symtab): Rename to psymtab_to_symtab2. Initialize
3565 new symtab completely. New psymtabs get symtab pointer
3566 initialized to zero. Remove MI warning printf.
3567 symtab.h: Comments. Add psymtab to symtab pointer.
3568 (PSYMTAB_TO_SYMTAB): New macro.
3569 symtab.c: use PSYMTAB_TO_SYMTAB. Add psymtab_to_symtab and export it.
3570 source.c: use PSYMTAB_TO_SYMTAB. Remove symtab version and
3572 stack.c (backtrace_command): Avoid pre-pass to read symbols, if
3574 (print_frame_info): Avoid special-casing symbols that have not yet
3577 * source.c (open_source_file): Quick path if we have already
3578 located the source file by its full name.
3580 * symtab.c (lookup_symbol): Use find_pc_symtab rather than
3581 find_pc_psymtab. When a name is found in the misc function
3582 vector, search the symbol table for its mangled name, not the
3583 name that the user typed.
3585 * bfd.h: Fix missing comment terminators, make #endifs match.
3587 * valarith.c (value_less): Handle unsigned int comparisons.
3588 Add FIXME about pointer compares, which assume host and target
3589 pointers are the same.
3591 * command.c (do_nothing_command): lint
3592 dbxread.c: lint. Remove sort_syms. Document C++ visibility info,
3593 fix comments on debug symbol format for visibility. Actually set
3594 visibility of symbols.
3595 main.c (echo_command): lint; use <readline/history.h>.
3596 tm-sparc.h (FRAME_FIND_SAVED_REGS): lint
3597 obstack.h (_obstack_blank): Rearrange pointer math to avoid
3598 pointing past end of allocated memory; saber complains.
3599 obstack.h: Declare the external functions that we use.
3600 valarith.h: use <string.h>
3601 solib.c (solib_add): lint.
3603 Fri Sep 21 17:05:19 1990 John Gilmore (gnu at cygint)
3605 * main.c (initialize_main): Default info_verbose to off, now that
3606 symbol reading is fast.
3607 (quit_command): Avoid clobbering exec_bfd while quitting.
3609 * Initial BFD (binary file diddling library) merger:
3610 coffread.c: Change AOUTHDR to struct exe_hdr.
3612 core.c: initialize initialized data at compile time.
3613 (core_file_command): Move from coredep.c, convert to bfd.
3614 (xfer_core_file): Convert to bfd.
3615 exec.c (exec_file_command): use bfd routines.
3617 mips-tdep.c: Remove exec_file_command and friends.
3620 * coredep.c: (fetch_core_registers) Convert core_file_command to
3621 fetch_core_registers.
3622 mips-xdep.c, sparc-xdep.c, sun3-xdep.c: ditto.
3624 * utils.c: (error): Bogus crap, FIXME, to print bfd errors.
3625 (my_bfd_read): More bogosity, which I don't think we call.
3626 (program_name): Remove this atrocity asap!
3628 Wed Sep 19 13:36:41 1990 John Gilmore (gnu at cygint)
3631 values.c: allocate_repeat_value was not clearing the
3632 optimized_out field.
3633 (value_static_field): minor stylistic fix (wrong macro was used).
3634 valops.c (value_struct_elt_for_address): didn't work for C++
3637 * signame.c (_initialize_signame): Initialize signal names once.
3639 * breakpoint.h, command.c, copying.awk, defs.h, environ.c,
3640 exec.c, frame.h, infcmd.c, inferior.h, main.c, munch, sun3-xdep.c,
3641 symtab.h, tm-29k.h, valprint.c, value.h, values.c: Lint.
3643 * remote-eb.c: Support user-settable baud rates on the serial port.
3645 * tm-sun3.h (PREPARE_TO_STORE): fix typo.
3647 Fri Sep 14 13:28:29 1990 John Gilmore (gnu at cygint)
3649 * tconfig/sun3os4: Remove warning about native assembler,
3650 since it also occurs in the xconfig file.
3652 * findvar.c (registers): Allocate some slop after `registers'
3653 to prevent stray accesses from trashing the next variable.
3655 * tm-68k.h (REGISTER_BYTES): Allocate the right number of bytes
3656 on the sun-3, by changing the #ifdef from `sun3' (which is not
3657 defined by cc) to `sun'. Symptom was trashed builtin_type_XXX
3658 vars, which happened to follow `registers' in the executable.
3660 * readline/history.c (history_search): Heed gcc-2's advice
3661 and parenthesize && inside ||).
3663 * am29k-opcode.h, am29k-pinsn.c, am29k-tdep.c, remote-eb.c,
3664 tm-29k.c: Insert FSF copyright headers.
3666 * remote-eb.c: Better comments.
3668 * Makefile.dist: Update to 3.91.6.
3669 * TODO: note PREPARE_TO_STORE problem.
3671 Thu Sep 13 09:52:33 1990 Jim Kingdon (kingdon at cygint)
3673 * stack.c (frame_info): Only use FRAME_FIND_SAVED_REGS if defined.
3675 * remote.c: Wrap the whole file in #if !defined (SPECIAL_REMOTE).
3677 * infrun.c (wait_for_inferior, at end): Don't set up
3678 prev_* if the inferior no longer exists.
3680 * inferior.h (CALL_DUMMY_LOCATION): New macro, to replace
3681 CANNOT_EXECUTE_STACK.
3682 valops.c (call_function): Use it.
3684 * tm-convex.h: Add CALL_DUMMY_LENGTH for use by PC_IN_CALL_DUMMY.
3686 * inferior.h (PC_IN_CALL_DUMMY): New macro.
3687 infrun.c (wait_for_inferior, 2 places): Use it.
3689 * values.c (value_being_returned): Only use
3690 EXTRACT_STRUCT_VALUE_ADDRESS if defined.
3692 * Move PREPARE_TO_STORE from xm-sun3.h to tm-sun3.h to do the
3693 right thing for remote-eb.c.
3695 * sun3-xdep.c: Remove extraneous call to remote_store_registers.
3696 * sun386-xdep.c, hp300hpux-xdep.c, sparc-xdep.c: Ditto.
3698 * blockframe.c: Put get_frame_saved_regs inside #if !defined
3699 (FRAME_FIND_SAVED_REGS).
3701 * findvar.c ({fetch,store}_registers): Check for
3702 REMOTE_{FETCH_STORE}_REGISTER macro.
3704 * findvar.c (get_saved_register): Add argument lval and
3705 change meaning of argument addr.
3706 findvar.c: Change calls to get_saved_register to reflect
3707 new calling convention.
3708 valops.c (value_assign): Use get_saved_register instead of
3709 find_saved_register.
3711 Sun Sep 2 12:40:20 1990 Jim Kingdon (kingdon at cygint.cygnus.com)
3713 * coffread.c (read_one_sym): Make temp_aux an AUXENT, not
3714 an (uninitialized) pointer to one. Use "&" when passing it
3717 Fri Aug 31 22:57:54 1990 Jim Kingdon (kingdon at cygint.cygnus.com)
3719 * coffread.c (getfilename): Use DGUX x_offset and x_name if
3722 * coffread.c (symbol_file_command): Put semicolon after
3724 Put safe_to_init_tdesc_context in #if defined (TDESC).
3725 Put #ifdef TDESCs in 1st column for non-ANSI cpp's.
3726 coffread.c: #include <sys/stat.h>.
3727 (read_coff_symtab): Typo: in_source_files -> in_source_file.
3728 Add missing ')' in check for "lc%" and friends. Remove
3730 Declare read_one_sym() at top of file.
3731 (read_file_hdr): Put in extra #ifdefs so MC68MAGIC and
3732 MC68WRMAGIC can have the same value without causing a duplicate
3735 Thu Sep 13 15:55:36 1990 John Gilmore (gnu at cygint)
3737 * Allow a Makefile to be built without building the
3738 tm and xm file links that screw up builds in subdirectories.
3739 This is done with `config.gdb none', then you can do things
3740 like `make gdb.tar.Z'.
3741 * tconfig/none: Config file for no target system
3742 * xconfig/none: Config file for no host system
3743 * config.gdb: If no TM or XM files are called out by the
3744 host or target file, don't make links for them.
3746 * cplus-dem.c: Add documentation.
3748 * dbxread.c (read_ofile_symtab): Turn a fatal error into a
3749 simple error, so the user's gdb doesn't crash due to some object
3750 file problem (e.g. somebody is rebuilding the file out from under
3753 * printcmd.c (print_address_symbolic): demangle the symbol.
3755 * Makefile.dist (OTHERS): Remove tdesc-lib because it has
3756 Motorola copyrights in it. Make "make gdb.tar.Z" work.
3757 (alldeps.mak): sort and uniq all results from this; duplicates
3758 hose gdb.tar.Z link building. Remove RCS files from
3759 tconfig and xconfig. Add config files for sun386. Add
3760 a few odd files to OTHERS and HFILES.
3762 Mon Sep 10 21:20:24 1990 John Gilmore (gnu at cygint)
3764 * Makefile.dist: Pull solib.c to tconfig/sun?os4.
3765 Roll version number to 3.91.5. Make lint work in bindir.
3767 * README: Document cross-debugging and new file structure.
3769 * blockframe.c: Lint. Include "value.h" to declare read_register.
3770 (find_pc_partial_function): remove duplicate line.
3772 * command.h: Lint. Declare error_no_arg and dont_repeat.
3774 * tm-news.h: Remove inadvertently duplicated stuff.
3776 * mipsread.c: Remove cache_pc_function stuff, now done cleanly.
3777 Clean up usage of misc_function_type. Declare some CORE_ADDRs.
3779 * config.gdb: Allow `config.gdb host target' form. Clean
3780 up previous change that printed bogus messages when you just said
3783 * core.c: #include "command.h" for lint.
3786 * main.c: Remove some casts of enums. Lint.
3793 * printcmd.c (initialize_printcmd): Fix thinko in inspect cmd.
3795 * sparc-tdep.c (isannulled): Take instruction as parameter, don't
3796 read it from memory. This will allow us to save ptrace calls
3797 eventually. Changed caller single_step too.
3799 * sparc-xdep.c (fetch_inferior_registers): Avoid reading regs
3800 that we aren't going to use, saving many ptrace calls, especially
3801 when watchpointing or single stepping. Use some #define's for
3803 (store_inferior_registers): Ditto.
3804 (core_file_command): Use some #define's for constants.
3806 * tm-sparc.h: Add #define's for some register numbers, so we
3807 can eliminate the use of random constants in sparc-xdep.c.
3809 * stack.c (frame_command, print_frame_info, up_command,
3810 down_command) Remove frame_changed, since it
3811 causes a bug and doesn't seem to do anything useful. In some
3812 places it was used as a flag, in others as a stack level (?).
3814 * utils.c: Use MISSING_VPRINTF rather than HAVE_VPRINTF, so the
3815 default is to use the portable (vprintf) version rather than the
3817 * xm-news.h (MISSING_VPRINTF): Add.
3819 * valprint.c (val_print): Demangle fancy vtbl printouts. Lint.
3821 Sat Sep 8 00:24:12 1990 John Gilmore (gnu at cygint)
3823 * Remove stuff that forces -Bstatic linking of gdb, and warnings
3824 about linking debugged programs -Bstatic in the sun?os4 config
3825 files in tconfig and xconfig subdirectories.
3827 * main.c (main): Remove unreached exit(0) now that we exit
3830 * Create TODO file for online bug list. There are too many
3831 "little" bugs to keep track of on paper.
3833 * Change Projects file to refer to bug-gdb@cygnus.com
3834 rather than kingdon@ai.
3836 Fri Sep 7 23:35:15 1990 John Gilmore (gnu at cygint)
3838 * Makefile.dist (VERSION): 3.91.4 now.
3840 * symtab.c (init_misc_bunches): Rename from init_misc_functions.
3841 (condense_misc_bunches): Add sanity check that misc_count is
3842 the same as the number of symbols in the bunch.
3844 * coffread.c: rename init_misc_bunches. Pass an argument
3845 to condense_misc_bunches (a zero).
3847 * dbxread.c (partial_symbol_file_read): Call init_misc_bunches
3848 every time we are called; don't rely on our caller to do it.
3849 (add_file): Remove call to init_misc_bunches.
3851 * mipsread.c: Only warn, don't error, if unknown symbol types.
3852 This keeps an old gdb from falling on its face if it sees newly
3853 extended symbol info. Rename init_misc_bunches.
3855 Fri Sep 7 22:58:15 1990 John Gilmore (gnu at cygint)
3857 * Merge in changes from Per Bothner for DECstations and other
3858 MIPS stuff. The rest is Bothner speaking:
3860 The next message is a merger of Alessando Forin's mips port with
3861 mine. I've tried to use my good if biased judgment to get
3862 the best of both. It *does* need testing.
3864 Some of the changes are general, *not* mips-specific.
3867 Didn't believe in little-endian bit order.
3868 There are still inconsistencies about whether flags
3869 like BITS_BIG_ENDIAN are integer (#if ...) or
3870 boolean (#ifdef ...). I tried to paper over them.
3872 dbxread.c,coffread.c,mipsread.c,symtab.c,symtab.h:
3873 Moved some misc_function code that was common to
3874 {dbx,coff,mips}read.c to symtab.c.
3875 In the process, I think I cleaned things up a bit.
3876 At the same time, moved obsavestring and obconcat to symtab.c.
3879 Removed obsolete condense_addl_misc_bunches (use
3880 condense_misc_bunches(1) instead).
3883 Needed to include <sys/dir>, at least on DECstations.
3885 valops.c, mips-tdep.c, tm-mips.h:
3886 Added PUSH_ARGUMENTS macro to support funny argument-pushing
3887 conventions (when STACK_ALIGN is insufficient).
3888 Needed on mips, where doubles need 8-byte alignment,
3889 but ints only need 4.
3892 Removed cruft that was not being used.
3893 Merged in many fixes (most from Frank Yellin, fy@lucid.com).
3896 Print $ before register-names (I think that makes things a little
3898 Never print two instructions, even if one delays.
3899 Removed hex-disassemble set_cmd. (This is not mips-specific,
3900 so I think the argument is whether it is generally worthwhile or not.
3901 I'm inclined to think not, given how easy it is to
3902 convert between radixes in gdb.)
3905 This is basically Alessando's code.
3906 It doesn't use obstacks; I changed it to use obstacks
3907 in a few minor places where using malloc causes a
3908 memory leak. (Probably, more places could/should be changed.)
3909 I added record_misc_function where it was missing.
3910 In symbol_file_command and add_file_command, I tried
3911 to make the code consistent with more recent versions.
3912 Minor sylistic changes in parse_procedure.
3913 Make a .gdbinfo. psuedo-symbol point back to the real
3914 procedure symbol (using the isym field).
3917 This is basically from my port, but with a lot of details
3918 and a number of routines merged in from Alessando's version.
3919 I basically used my code "raw" backtrace (use heuristics
3920 from the actual code, rather than symbol table info) - though
3921 the idea is Alessandro's. I feel my code is a little cleaner
3922 here, particularly in being a little more flexible, such as being
3923 able to handle gcc-produced code (which it now can).
3924 It also doesn't do frame caching (which is not useful
3925 more recent gdb versions).
3926 I also used my code for push_/pop_dummy, more or less.
3927 I tried to incorporate AF's code for testing sigtramp
3928 while backtracing; I probably got it wrong.
3929 Added mips_print_register, which tries to scrunch as much
3930 information as possible on a screen...
3931 Removed the skip-prologue set_cmd. As with hex-disassemble (see
3932 under mips-pinsn.c), I don't see anything mips-specific here,
3933 and I don't see it being all that useful anyway.
3936 Added a $fp psuedo-reg distinct from $fp (nice for gcc).
3937 Use more register names (rather than hard-cases numbers).
3939 Thu Sep 6 18:33:15 1990 John Gilmore (gnu at cygint)
3941 * Hack up 3.90.11 changes:
3943 * Makefile.dist (depend): parameterize $(GCC).
3944 Add solib.c and solib.o.
3945 (readline): Fix vpath for both absolute or relative SRCDIR.
3947 * blockframe.c: Fix from Schaefer@asc.slb.com for shared libs.
3948 Also, let the part I didn't understand at least compile so
3949 I can test the rest. FIXME.
3951 * dbxread.c: Fix thinko using strcmp.
3952 (init_psymbol_list): declare static.
3953 (partial_symbol_file_open): Comment cleanups better, avoid
3954 cleaning up the string table since the caller will do that.
3955 Move the stat for mod time into symbol_file_command, temporarily.
3956 (There should be a mod time for each symbol file, eventually,
3957 to control its rereading. FIXME.)
3959 * infptrace.c (PT_WRITE_D): use same value as PT_WRITE_I for
3960 SunOS, which gives error for shared libs otherwise. (From
3961 Schaefer, probably FIXME needs work for portability.)
3963 * solib.c: Move #include "param.h" to work.
3964 Lowercase all the Uppercase Letters In the Messages.
3965 (find_solib): Clean up inferior_so_name for debug printouts.
3966 Allow no argument, to mean all shared libraries.

3994 Put parens around gcc_p in expansion.
3996 Thu May 24 15:44:51 1990 Jim Kingdon (kingdon at mole.ai.mit.edu)
3998 * utils.c (lines_to_list): Return 10 if lines_per_page == 0.
4000 Wed May 23 16:36:04 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
4002 * Changes for Sun shared libraries:
4003 blockframe.c (find_pc_partial_function): If a non-text symbol
4004 is found, set *address = pc - FUNCTION_START_OFFSET.
4005 breakpoint.c (insert_breakpoints) [DISABLE_UNSETTABLE_BREAK]:
4006 Disable breakpoints instead of giving an error.
4007 source.c (select_source_symtab): Initialize cs_pst.
4008 symmisc.c: Call CLEAR_SOLIB if defined.
4009 symtab.h: Make text{low,high} CORE_ADDR not int.
4010 (psymtab): New field addr.
4012 dbxread.c: Move DECLARE_FILE_HEADERS outside functions.
4013 (record_misc_function): Give correct type for N_DATA symbols.
4014 (condense_misc_bunches): do "misc_function_count = j" regardless
4016 Take code which is shared between symbol_file_command and
4017 add_file_command and put it into partial_symbol_file_{open,read}.
4018 Split add_file_command into add_file_command and add_file.
4019 Make psymtab_to_symtab read in the string table if the file
4021 Two new parameters to read_dbx_symtab and start_psymtab.
4022 tm-sunos.h: New file.
4024 Tue May 22 17:43:03 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
4026 * infcmd.c: Change cont_command to continue_command and "cont"
4029 Mon May 21 14:41:41 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
4031 * breakpoint.c (enable_breakpoint): Get value of watchpoint.
4033 * defs.h [sparc]: Use <alloca.h> regardless of __GNUC__.
4035 * values.c (USE_STRUCT_CONVENTION): Check for structures of
4036 size 1,2,4,8 rather than size < 8.
4038 * dbxread.c (dbx_lookup_type): Do f->length *= 2 as many times
4039 as necessary, not just once.
4041 * sparc-opcode.h: Add a bunch of new opcodes which Sun as supports.
4043 Thu May 17 15:04:09 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
4045 * {t,x}m-sun386.h, sun386-xdep.c, {x,t}config/sun386
4047 * tm-news.h: Add CALL_DUMMY_*.
4049 * tm-68k.h: Remove duplicate comment at FRAME_FIND_SAVED_REGS.
4051 * config.gdb: In list_host, list_target, use ${i}, not $i.
4053 Tue May 15 21:27:12 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
4055 * source.c (find_source_lines) [BROKEN_LARGE_ALLOCA]: Use xmalloc.
4057 * sparc-opcode.h: Change all store floating-point state register
4058 instructions to have the right match & lose fields.
4060 Sat May 5 12:39:18 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
4062 * Makefile.dist: Move -I${srcdir} to GLOBAL_CFLAGS and pass
4064 config.gdb: If srcdir != ., create readline directory and
4065 copy a makefile into it.
4067 * wait.h, infrun.c: Change WRETCODE to WEXITSTATUS for
4068 consistency with POSIX.
4070 * breakpoint.c (bpstat_stop_status): Disable watchpoint
4071 when we exit its exp_valid_block.
4073 Tue Sep 4 11:46:46 1990 John Gilmore (gnu at cygint)
4075 * Makefile.dist: Bump version to 3.91.3.
4077 * Clean up handling of breakpoint commands (somewhat).
4078 Prompted by Tiemann bug report "cont 10" doesn't work any more.
4080 inferior.h: Add breakpoint_proceeded to inferior status struct
4081 and globals; save it and restore it.
4082 (clear_breakpoint_commands): Cleanup, remove old #define.
4084 infrun.c (clear_proceed_status): Set breakpoint_proceeded.
4085 (save_inferior_status, restore_inferior_status): handle it also.
4086 (proceed): Remove earlier code that set breakpoint_proceeded.
4087 It is now set only in clear_proceed_status.
4088 (clear_proceed_status): Cleanup, use bpstat_clear rather
4089 than clear_breakpoint_commands. No callers need the stop_bpstat
4090 between clear_proceed_status and proceed.
4092 infcmd.c: Add breakpoint_proceeded definition and comment.
4093 (cont_command, jump_command, signal_command): Move call to
4094 clear_proceed_status right next to call to proceed.
4096 breakpoint.c (bpstat_do_actions): Avoid clobbering our
4097 caller's argument while running down the chain of breakpoints.
4098 Use new variable "breakpoint_proceeded" to determine when
4099 a command that it executes moves the inferior past the
4101 (bpstat_clear): Handle NULL argument.
4102 (bpstat_clear_actions): Avoid useless call to
4103 breakpoint_auto_delete.
4104 (delete_breakpoint): Clean up bpstat's that are pointing to
4105 the deleted breakpoint from the stop_bpstat chain.
4106 (breakpoint_auto_delete): Simplify.
4108 * Clean up handling of EOF, error on stdin, etc. This was
4109 prompted by a network problem that caused gdb to go into an
4110 infinite loop filling up its malloc'd memory.
4112 main.c (return_to_top_level): Cleanup: call bpstat_clear_actions,
4113 not clear_breakpoints_commands, which is now gone.
4114 (main): If command_loop returns (e.g. from EOF on stdin), do
4115 a quit_command (looping back to command_loop if quit_command
4116 doesn't really quit).
4117 (command_loop): check result from command_line_input and
4118 exit if it returns NULL, rather than passing the NULL to
4120 (gdb_readline): Free malloc'd result space before returning
4123 * utils.c (query): Handle C-d to mean "yes", just as if the
4124 input was not a terminal. Also avoid infinite loop if EOF
4125 occurs in mid-input-line before newline. This allows
4126 query to be used at EOF on stdin with reasonable results.
4128 * infrun.c (proceed): Set breakpoint_proceeded.
4130 * values.c (value_as_long): Avoid infinite recursion for enums.
4131 (_initialize_values): Fix typo in help msg (kingdon).
4133 * Makefile.dist (RL_LIB): Use RL_LIB_DEP for dependencies,
4134 RL_LIB for linking. This allows -lreadline for linking
4135 and nothing for dependencies, once readline is a real library.
4137 * config.gdb: Jim Kingdon: give useful error message if the
4138 host or target type is not recognized.
4140 * defs.h (alloca): SPARC <alloca.h> does not declare alloca,
4141 it just defines it. Dumb, but deal with it.
4143 * Jim Kingdon suggests:
4144 in xconfig/sun3os4, CFLAGS should be XM_CFLAGS.
4146 Wed Aug 29 18:03:27 1990 John Gilmore (gnu at cygint)
4148 * Makefile.dist (VERSION): Bump version # to 3.91.2.
4150 * Clean up Bothner's changes.
4152 * blockframe.c (clear_pc_function_cache): New function.
4153 * blockframe.c: remake cache_pc_function_* static.
4154 * dbxread.c (symbol_file_command): remove references to
4155 cache_pc_function_* variables.
4156 * dbxread.c (read_struct_type): Use VOFFSET_STATIC.
4157 * printcmd.c: Avoid kludging a global variable (addressprint)
4158 to avoid printing the address of a string twice. Instead,
4159 pass the format letter 's' down low enough that it can be seen
4160 to avoid this problem.
4161 (print_formatted): Pass format arg to value_print.
4162 (restore_addressprint): Remove function.
4163 (do_examine): Avoid hacking addressprint, cleanups and such.
4164 (print_frame_args): Add a comment to a Bothner change.
4165 * symtab.h: define VOFFSET_STATIC and use it instead of "-1".
4166 * symmisc.c (free_all_symtabs): Call clear_pc_function_cache
4167 to wipe out the values cached in blockframe.c.
4168 * symtab.c (find_method): Add comment saying how big you must
4169 allocate to be "big enough". Per being terse again.
4170 * valprint.c (val_print): Handle format letter "s" to print
4171 strings without addresses. Add comment to vtbl printing code
4172 which casts with wild abandon. Rearrange reference-printing
4174 @0xaddr: value (print w/addressprint)
4175 value (print w/~addressprint)
4176 @0xaddr (parameter lists w/addressprint)
4177 or nothing (parameter lists w/o addressprint)
4179 Tue Aug 28 10:47:18 1990 John Gilmore (gnu at cygint)
4181 * Merge more changes from Per Bothner:
4183 Gdb's handling of TYPE_CODE_REF was so counter-C++ (and otherwise
4184 annoying) that I tried to improve it. Here are my suggestions.
4186 These patches all attempt to handle TYPE_CODE_REF (as in C++) better.
4189 Do automatic de-reference when taking the address of a reference.
4191 Don't deref_ref when printing parameter lists.
4193 More attempts at treating refernences properly.
4195 In val_print, if deref_ref==0, don't print dangling " = ".
4197 Add COERCE_REF macro, which de-references an REF.
4199 * Merge changes from Per Bothner:
4201 * Fixed (Sony news)-specific configuration problems.
4202 * Fixed other problems with using vanilla pcc and libc (enum problems;
4203 assumption that vsprintf exists).
4204 * Some major speed-ups (finc_pc_partial_function now caches a match;
4205 parsing avoids duplicate symbol_lookup calls).
4206 * Changed handling of baseclasses (no longer use baseclasses field
4207 of struct type, use the first n_baseclasses fields instead).
4208 * Various minor changes/fixes, most C++-related.
4211 Cache the most previous match from find_pc_partial_function.
4212 (Save both low and high ends of matching function's pc range.)
4213 This speeds up the loop of infrun.c:wait_for_inferior quite
4214 a bit, and makes step/next commands much zippier.
4216 Added an enum->int cast (otherwise, some compilers barf).
4218 No longer set baseclass offset to 0, since multiple
4219 inheritance now mostly works.
4220 Added a number of casts, to shut up compiler warnings
4221 (after stabs where made enums, not ints).
4222 When discarding a symbol table (in symbol_file_command),
4223 must clear the cache introduced in blockframe.c.
4224 Don't convert $vtbl_ptr_type to vtbl any more.
4225 Get rid of TYPE_BASECLASEES and baseclass_vec (see also symtab.h).
4226 Mask off sign bit emitted by g++ for virtual table offset.
4227 Set voffset to -1 (not 1) for static member functions.
4229 Changed parsing/lexing of names to avoid doing symbol lookup twice
4230 (once when lexing to determine symbol class, once for real).
4231 Now only call symbol_lookup once. Fields of 'this' win especially big.
4233 Subpress printing addr twice in the case of 'x/s addr'.
4235 lookup_basetype_type is no longer used.
4236 Add find_methods as recursive helper function to decode_line_1.
4237 This allows multiple inheritance to work.
4238 Also, once one or more matches has been found, do not look in
4239 base-classes. (Baseclass methods would be overridden, anyway.)
4241 Removed baseclasses array in struct type.
4242 Instead of using baseclasses[i], use fields[i-1].
4243 Added virtual_field_bits[i] to indicate if the i'th baseclass is virtual.
4244 Changed sign convention of voffset (previous was inconsistent).
4246 Some macros (CALL_DUMMY and relatives) were missing. Put them back.
4248 Used to assume existence of vsprintf. Re-written to not need it
4249 if HAVE_VPRINTF is undefined.
4251 typecmp was too pessimistic. Made it less so.
4253 Don't print space after address.
4254 If vtable points to a misc symbol (with 0 offset), print it,
4255 since that indicates the actual class of the object.
4256 Changed ype_print_derivation_info to use new inheritance
4257 scheme (without baseclasses vector).
4259 In value_primitive_field, fixed some bugs left over from previous set of fixes.
4260 Also, changes needed because TYPE_BASECLASSES were removed.
4262 REGISTER_U_ADDR didn't work for PC. Rewrote to use an array.
4264 Tue Aug 21 20:08:54 1990 John Gilmore (gnu at cygint)
4267 If there is no path set, and the symbols don't indicate what directory
4268 a file was compiled in, look in the current directory. But either
4269 a path or a known compilation directory will prevent this.
4272 Three independent bug fixes:
4273 * Remove the #if 0 block that breaks some stuff.
4274 * SunOS 4.1 fixed the promoted-parameter-wrong-addr bug in Sun C;
4275 adapt gdb to either SunOS 4.0.* or 4.1.
4276 * MAX_OF_TYPE and MIN_OF_TYPE thinko. By tedg@sun, I think.
4279 Instantiate the class T when looking for methods in it. (Tiemann@sun)
4282 (type_print) Demangle the name being printed.
4283 (type_print_base) Handle botched demangling without coredump (tiemann).
4286 (check_stub_method): Document routine.
4287 (tiemann) fix bug for no-arg functions
4288 Avoid clobbering beyond end of malloc'd storage.
4289 Terminate the argument list properly.
4291 Sat Aug 18 01:29:59 1990 Per Bothner (bothner@cs.wisc.edu)
4293 * Changes merged by John Gilmore:
4296 In breakpoint_1, use new print_address_symbolic instead
4297 of find_pc_partial_function. (This forces use of assembler-level
4298 addresses, and avoids misleading non-mangled source-level names.)
4300 Generalize ansi argument such that -1 means skip arglist totally.
4301 Removed global variable print_ansi_qualifiers (which made
4302 code non-reentrant), in favor of extra explicit arguments
4303 to internal routines.
4305 Add new helper function print_address_symbolic.
4306 Use find_pc_misc_function instead of find_pc_partial_function
4307 (since we want assembler-level symbols here).
4309 Print unknown function as just "f (...)", not "f (...) (...)".
4310 Use new fputs_demangled explicitly.
4312 Fixed a typing violation (problem: value.h cannot be imported
4313 without renaming many variable in this file).
4314 lookup_symbol: If no matching misc_func, look for a C++-mangled name.
4315 decode_line_1: Moved forward some never-reached code.
4316 Made decode_line_2 skip function prologues correctly.
4318 fputs_filtered should not demangle by default.
4319 Add new fputs_demangled to demangle on demand..
4321 Change value_struct_elt to use value_primitive_field (using recursive
4322 utility function search_struct_field). This allows foo.bar to work
4323 for multiple inheritance (so far only for data fields).
4324 Change check_field in the same way (recursive helper function
4325 to support multiple inheritance).
4326 (Note: there are more of these problems that I haven't fixed.
4327 Any code that says TYPE_BASECLASS (t, 1) is probably wrong.)
4328 value_of_this: 'this' symbol name is now just "this", note "$this".
4330 Don't print static members.
4331 Avoid printing "members of <type>" if there are none.
4332 Simplified type_print_derivation_info by merging duplicate code.
4333 Remove useless blank lines in type_print_base (ptype command).
4335 Added declaration of new routine value_primitive_field.
4337 Added value_primitive_field which is generalized version of
4338 value_field that can handle multiple inheritance (non-zero offsets etc).
4339 Re-implemented value_field to call value_primitive_field.
4341 Fri Aug 17 23:33:44 1990 John Gilmore (gnu at cygint)
4343 * infcmd.c -- insert else to avoid 'delete env' coredump when you
4344 delete the whole environment. Karl Berry reported the bug.
4345 * source.c - fix openp to avoid //'s in filenames, which
4346 trigger an Emacs bug causing it to not be able to find files
4347 when running gdb in a window.
4348 * dbxread.c - zap the #if 0 that botches the add-file code.
4349 It seems to work a lot better without all the code commented out.
4351 Fri Jul 20 16:58:46 1990 John Gilmore (gnu at cygnus.com)
4353 * Merge Tiemann's and Ted Goldstein's changes, detailed below,
4356 Tue Jul 17 19:34:33 1990 Ted Goldstein (tedg at golem)
4358 * Makefile - added a ${CFLAGS} to a couple of entries,
4359 added remote-sa.sparc.c
4360 * added remote.sa-sparc.c, a modification of remote.c
4361 which conducts a dialog directly with the SparcStation prom.
4362 * breakpoint.c, infrun.c, sparcdep.c added
4363 remote_insert_breakpoint(), and remote_remove_breakpoint()
4364 to breakpoint.c instead of directly writing breakpoint instructions.
4365 * sparcdep.c on remote_debugging,there is no need
4366 to remove signle step breakpoint instructions.
4367 * main.c added "-epoch" flag and "int epoch_interface" to main.c
4369 * printcmd.c - epoch interface sends lisp expressions to open up
4370 epoch windows on inspection.
4371 * valprint.c - added arrayprint, and addressprint and made adding
4372 format controls easier
4373 * wait.h added a couple of undef's because we were getting
4374 complaints about WSTOPSIG and WTERMSIG begin redefined.
4377 Wed Jul 4 05:27:51 1990 Michael Tiemann (tiemann at masham)
4379 * symtab.c (decode_line_1): Add support for handling method stubs
4380 in the type information.
4382 Tue Jul 3 09:39:18 1990 Michael Tiemann (tiemann at masham)
4384 * values.c (baseclass_addr): Run loop from INDEX+1 to
4385 N_BASECLASSES; otherwise, we can still get into a loop.
4386 @@ This should be restructured to use a cleaner search strategy.
4388 Sun Jul 1 12:28:51 1990 Michael Tiemann (tiemann at masham)
4390 * dbxread.c (define_symbol,read_type): Grok GNU C++'s new
4391 abbreviation "Tt" for tags which have the same name as their
4394 Fri Jun 29 01:03:46 1990 Michael Tiemann (tiemann at masham)
4396 * symtab.c (list_symbols): add ability to set breakpoints on all
4397 the functions which match a particular regular expression.
4399 Tue Jun 26 04:26:29 1990 Michael Tiemann (tiemann at masham)
4401 * cplus-dem.c (cplus_demangle): New parameter ANSI says whether we
4402 should print ANSI qualifiers (such as `const' and `volatile').
4403 All callers changed to call with ANSI == 1, except from
4404 `check_method_stub', which uses old-style syntax.
4406 * symseg.h (struct fn_field): Remove unneccessary `args' field.
4407 * symtab.h (TYPE_FN_FIELD_ARGS): Redefined.
4409 * values.c (check_stub_method): New function.
4411 * cplus-dem.c (do_type): Handle "long long" (encoded as 'x').
4413 * dbxread.c (read_type): Handle new GNU C++ method type stubs.
4414 * valprint (type_print_base): Ditto.
4416 * symtab.c (gdb_mangle_typename): New function.
4418 Tue Jun 5 00:18:43 1990 Michael Tiemann (tiemann at gzilla)
4420 * breakpoint.c (catch_command): New function. Provides a
4421 mechanism to set breakpoints based on catch clauses.
4422 (disable_catch): Similar, but disables breakpoints on catch
4424 (delete_catch): Similar, but deleted breakpoints on catch clauses.
4426 Sun Jun 3 22:54:08 1990 Michael Tiemann (tiemann at gzilla)
4428 * blockframe.c (blockvector_for_pc): New function.
4429 * blockframe.c (block_for_pc): Changed to call
4430 `blockvector_for_pc' and get the block itself.
4432 * stack.c (catch_info): New function. Prints info about
4433 exceptions which can be caught in the current frame.
4434 * stack.c (print_frame_label_vars): New function. Similar to
4435 `print_frame_local_vars'.
4436 * stack.c (print_block_frame_labels): Prints out labels that are
4437 defined in this frame. These labels are exceptions that can be
4440 * dbxread.c: Updated to handle N_CATCH symtab types.
4442 Thu May 3 22:10:00 1990 Michael Tiemann (tiemann at teacake)
4444 * valprint.c (everywhere): TYPE_NAME (TYPE) no longer comes in the
4445 form "struct ..." for GNU C++. Don't flush any part of TYPE_NAME
4446 when printing the type.
4448 Wed May 2 22:43:04 1990 Michael Tiemann (tiemann at teacake)
4450 * valprint.c (val_print): Use `baseclass_addr' to access the
4451 baseclasses pointed to via the derived class object at VALADDR.
4453 * values.c (baseclass_addr): New function. Casts derived pointers
4454 to baseclass pointers taking virtual baseclasses and multiple
4455 inheritance into account.
4457 Sat May 5 12:39:18 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
4461 Fri May 4 12:12:55 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
4463 * breakpoint.c (watch_command, bpstat_stop_status): Deal with
4464 exp_valid_block field correctly.
4466 * infrun.c (wait_for_inferior): When checking "don't even think
4467 about breakpoints" if stop_signal == SIGTRAP && trap_expected,
4468 also check step_resume_breakpoint.
4469 Insert breakpoints and continue (not step) if
4470 step_resume_break_address != NULL, even if another_trap.
4471 If trap_expected and we enter sigtramp, then set up a
4473 If trap_expected is set when we hit the step_resume_break,
4475 When calling resume and trap_expected says tell resume to step
4476 (2 places), also check step_resume_break_address.
4478 * infrun.c (wait_for_inferior): Don't set
4479 prev_{pc,sp,func_{start,name}} before calling wait ().
4480 Do set them after exiting loop.
4481 Move their declarations outside functions.
4482 (start_inferior): Initialize them.
4484 Thu May 3 00:15:11 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
4486 * infrun.c (wait_for_inferior, after check for trap_expected > 1):
4487 Restore old code which distinguishes between trap_expected and
4488 running_in_shell, just make the latter take any non-TRAP signal,
4491 * values.c (allocate_value): Zero VALUE_OPTIMIZED_OUT flag.
4493 * Makefile.dist (pinsn.o): Use PINSN_CC to compile.
4494 xconfig/3b1 (CC,PINSN_CC): Define.
4496 * xconfig/altos, altos-dep.c: Rename altos-dep.c to altos-xdep.c.
4500 * breakpoint.c (bpstat_stop_status),
