1 Thu Oct 24 23:06:40 1991 Fred Fish (fnf at cygnus.com)
3 * tm-3b1.h, tm-68k.h, tm-altos.h, tm-amix.h, tm-hp300bsd.h,
4 tm-hp300hpux.h, tm-isi.h, tm-news.h, tm-pn.h, tm-sun2.h,
5 tm-sun3.h: Remove locally duplicated code for calling functions
6 in the inferior. The only differences were in the specific trap
7 vectors used and whether or not an fpu was present. These are
8 now handled by appropriate definitions of BPT_VECTOR and
9 HAVE_68881 respectively. Other minor obvious cleanups.
11 * valops.c: Correct a minor misspelling.
13 * utils.c: Remove local BSD/USG hacks that are now in libiberty.
15 * dwarfread.c: Remove prototype for dwarfwarn. Does not work
18 Thu Oct 24 09:33:44 1991 John Gilmore (gnu at cygnus.com)
20 * stack.c (frame_command): Always print. Use new
21 frame_select_command to select a frame without printing.
23 * dwarfread.c: Use <varargs.h>, since <stdarg.h> is not portable.
25 Thu Oct 24 01:32:51 1991 Fred Fish (fnf at cygnus.com)
27 * dwarfread.c: New file for DWARF debugging format support.
29 * elfread.c: New file for ELF object file format support.
31 * procfs.c: New file for SVR4 /proc (process file system) support.
33 * tm-amix.h, xm-amix.h, tconfig/amix, xconfig/amix: New files for
36 * xm-svr4.h, tm-svr4.h: New files for SVR4 support.
38 * xm-m68k.h: New file for host machines with m68k cpu.
40 * Makefile.in: Add elfread.c and dwarfread.c to SFILES_MAINDIR.
41 Add elfread.o and dwarfread.o to OBS.
43 * symfile.h: Add "elf" to list of supported formats in comment.
45 * c-exp.y, defs.h, symtab.h, valprint.c: Add three new builtin
46 types to gdb, builtin_type_long_double, builtin_type_complex, and
47 builtin_type_double_complex. Add and use new TARGET_SHORT_BIT,
48 TARGET_INT_BIT, TARGET_LONG_BIT, TARGET_FLOAT_BIT,
49 TARGET_DOUBLE_BIT, TARGET_LONG_DOUBLE_BIT, TARGET_COMPLEX_BIT, and
50 TARGET_DOUBLE_COMPLEX_BIT, as the sizes in bits of the indicated
51 types on the target machine (ala the existing TARGET_LONG_LONG_BIT).
53 * infrun.c: When using SVR4 /proc interface instead of ptrace(),
54 call proc_set_exec_trap() to setup child to stop at first instruction.
56 * inftarg.c: When using SVR4 /proc interface, call proc_wait()
59 * m68k-tdep.c: Add new routines supply_gregset(), fill_gregset(),
60 supply_fpregset(), and fill_fpregset(), which are machine
61 dependent support routines for SVR4 /proc interface.
63 * utils.c: Add warning_setup() and warning(). Warning() behaves
64 the same as error() except that it returns normally rather than
65 jumping back to command level. Modules that don't want to call
66 warning() for some reason, but want to produce their own warnings,
67 can call warning_setup() to ensure compatibility with the way
68 warning() and error() deal with the terminal.
70 * symtab.c: Make internal errors produce more useful messages.
72 * tm-68k.h: Move code that is duplicated in almost every single
73 m68k based machine's configuration files to this common file.
74 Duplications in the configuration files still need to be removed
77 * infrun.c (child_create_inferior): System V versions must call
78 setpgrp() with no arguments, to comply with prototyping typically
81 * munch: Add support for SVR4 style nm output.
83 * dbxread.c, mipsread.c symmisc.c, symtab.c: Remove the object
84 file specific fields from the partial symbol table structure and
85 replace them with a pointer to private data for each different
86 flavor of object file reader to initialize appropriately.
88 Wed Oct 23 09:38:20 1991 John Gilmore (gnu at cygnus.com)
90 * xconfig/sun[34]os4: Add note about strstr botch on sunos4.0.3c
93 * mipsread.c (fixup_undef_type): New function. If a struct /
94 union / enum is defined in a header file but nowhere else used,
95 (by typedefing, pointer referencing or declaration) the mipsread code
96 builds the complete tree for the structure but leaves its code as
97 TYPE_CODE_UNDEF as it doesn't know what kind of aggregate it is.
98 Guess its type based on the details of the members.
100 Tue Oct 22 18:04:32 1991 Stu Grossman (grossman at cygnus.com)
102 * infrun.c (wait_for_inferior): Check return value from
105 Mon Oct 21 17:47:03 1991 Stu Grossman (grossman at cygnus.com)
107 * infrun.c (wait_for_inferior): fix stepi/nexti that was broken
108 by my last edit to this routine.
110 Mon Oct 21 14:27:43 1991 John Gilmore (gnu at cygnus.com)
112 * tm-sun3.h (FIX_CALL_DUMMY): problem with cross debugging.
113 FIX_CALL_DUMMY does unaligned accesses and/or forgets to byte swap
114 the values before putting them into the dummy code. (From Peter
117 Mon Oct 21 10:04:39 1991 Steve Chamberlain (steve at rtl.cygnus.com)
119 * configure.in: added ebmon target.
121 Wed Oct 16 22:49:58 1991 John Gilmore (gnu at cygnus.com)
125 * Makefile.in: Roll VERSION to 4.2.
126 * README, TODO, WHATS.NEW: Update.
128 * core.c (core_open): Improve error message for bad file.
129 Pass .reg virtual memory address to fetch_core_registers to help
130 it find the registers in the core-file header.
131 * coredep.c (fetch_core_registers): Take new argument, use it,
132 and pass it to register_addr to locate the block of registers.
133 * xm-mips.h: Update KERNEL_U_ADDR for new scheme. Cleanup a bit.
135 * dbxread.c (read_dbx_symtab, process_one_symbol): Handle
136 Sequent N_FN_SEQ like everybody else's N_FN.
138 * main.c: Circumvent SCO cc bug with #if !!defined(USG).
139 * tm-i386v.h: #endif guck.
140 * xconfig/i386*: Remove -Dgetpagesize()=4096 kludge.
141 * xconfig/i386sco: Add HAVE_STRSTR to avoid ANSI bdeath.
142 * xconfig/tahoe: Add REGEX, which seems to be missing.
144 * coredep.c: Add <sys/types.h> for SCOnix.
145 * dbxread.c (read_dbx_symntab): Avoid coredump on malformed file.
146 * printcmd.c (print_formatted): Flush output before disassembly.
148 Tue Oct 15 20:12:32 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
150 * doc/refcard.tex (sec "Working Files"): consistent metavars and
151 other improvements, due to comments by François Pinard
152 (pinard@iro.umontreal.ca)
154 * doc/gdb.texinfo (appendix "Installing GDB"): changes in
155 configure, and improvenets related to Pinard's refcard comments
157 Tue Oct 15 08:45:12 1991 John Gilmore (gnu at cygnus.com)
159 Changes from Fred Fish:
160 * tm-68k.h (FPI_REGNUM): Add.

174 * i387-tdep.c (double_to_i387): Fix typo for double_to_ieee_extended.
175 * utils.c (_initialize_utils): If !ISATTY, don't paginate.
176 * configure.in, tconfig/decstation, xconfig/decstation: Rename
177 dec3100 to decstation.
179 Mon Oct 14 13:37:50 1991 Roland H. Pesch (pesch at cygnus.com)

182 (nodes Continuing and Stepping; Memory; Targets) clarifications
185 Fri Oct 11 23:27:06 1991 John Gilmore (gnu at cygnus.com)
187 * tm-{irix3,mips,nindy960,pn,symmetry,vx960}.h: Move
188 REGISTER_U_ADDR to corresponding xm- file. Sugg. by Peter Schauer.

193 generic routines for calling inferior functions.
195 * blockframe.c (inside_main_scope, inside_entry_scope): New.
197 * copying.awk: Filter formfeeds out of copying & warrantee.
198 Make them available as `show copying' and `show warrantee' also.

201 Thu Oct 10 17:25:47 1991 John Gilmore (gnu at cygnus.com)
203 * mach386-xdep.c: Even when cross-compiling, leave in the
204 core-file reading code.
205 * core.c (get_core_registers): Avoid coredump if no .reg section.
207 Wed Oct 9 17:03:34 1991 John Gilmore (gnu at cygnus.com)
209 * mipsread.c, coffread.c: initialise TYPE_VPTR_FIELDNO to -1.
210 This avoids coredumps under `set print object on' in value_headof
211 (called erroneously by value_from_vtable_info) for `p &struct'
212 or `p *struct'. From Peter Schauer.
214 Mon Oct 7 00:06:52 1991 John Gilmore (gnu at cygnus.com)
216 * Makefile.in: Roll version to 4.1.2.
217 * dbxread.c: Use aout64.h, not a.out.gnu.h. Get external symbol entry
218 size from BFD (but, FIXME, we don't yet read external nlists's and
219 convert them to internal nlists's before handling them -- we still
220 assume they have the same size and alignment.) Use SET_NAMESTRING
222 * exec.c (exec_file_command): Move dead coff-encapsulation code
224 * m88k-tdep.c, m88k-xdep.c: Remove encap test and #inc <a.out.h>.

228 * configure.in, tm-i386v.h, xm-i386v.h: Intel 386 Mach host port.
229 * xm-i386mach.h, mach386-xdep.c, xconfig/i386mach: New files.
231 Fri Oct 4 17:04:31 1991 Per Bothner (bothner at cygnus.com)
233 More patches from Peter Schauer <pes@regent.e-technik.tu-muenchen.de>:
234 * mips-xdep.c (store_inferior_registers): Don't try to
235 write the (pseudo) FP.
236 * mipsread.c (parse_partial_symbols): Improved algorithm for
237 setting pst->texthigh.
239 Fri Oct 4 16:47:32 1991 Roland H. Pesch (pesch at cygnus.com)
241 * doc/Makefile: make TEXINPUTS include . everywhere
243 Fri Oct 4 00:35:56 1991 John Gilmore (gnu at cygnus.com)
245 * coffread.c, dbxread.c, symfile.c, symmisc.c, symtab.h: Remove
246 vestiges of typevectors, which were for symsegs and are no longer
247 used. (From a question by Eliot Dresselhaus
248 <dresselh@RFT30.nas.nasa.gov>).
250 Thu Oct 3 09:33:26 1991 John Gilmore (gnu at cygnus.com)
252 * dbxread.c, coffread.c: static-ize functions that were
253 gratuitiously external. (From Fred Fish.)
255 * c-exp.y: sym->class to SYMBOL_CLASS (sym).
257 * dbxread.c (dbx_lookup_type): Keep doubling size of typevector
258 until it is large enough.
260 * dbxread.c (read_type): Handle error case slightly better.
261 Make complaint message not C++-specific.
263 Wed Oct 2 17:21:07 1991 Stu Grossman (grossman at cygnus.com)
265 * infrun.c (wait_for_inferior): Fix step/next so that you only
266 stop at the beginning of a new line. This fixes various problems
267 with for loops, nested if-else's and switch statements.
269 Tue Oct 1 06:33:55 1991 John Gilmore (gnu at cygnus.com)
271 * symtab.c (lookup_symtab_1, lookup_symbol): "fatal" errors
272 between symtabs and psymtabs become ordinary error()s.
274 * dbxread.c (read_dbx_symtab): Relocate end_of_text_addr
275 properly, making "end pc" correct in shared lib psymtabs.
276 (From Guy Harris <guy@auspex.com>.)
278 Mon Sep 30 13:15:31 1991 John Gilmore (gnu at cygnus.com)
280 * dbxread.c: Enable, but soften, const_vol_complaint.
281 (read_dbx_symtab): N_STSYM and N_LCSYM define static vars.
282 Ditto Gould N_NBSTS and N_NBLCS. Also, all types in the psymtab
283 should be file-scope, not global.
284 (read_struct_type): Remove ancient multiple-inheritance warning.
285 (read_range_type): Check base type, complain & patch if undefined.
286 * stack.c (frame_info): Demangle the function name in `info stack'.
289 Sat Sep 28 10:02:33 1991 John Gilmore (gnu at cygnus.com)
291 * eval.c (evaluate_subexp_for_address): Don't use
292 TYPE_POINTER_TYPE directly (it might be zero if this type has
293 never had a pointer created before); use lookup_pointer_type.
294 * symtab.c (lookup_method_type): Arguments were swapped in all
295 callers, so fix it here. I'm amazed this worked at all!
297 Fri Sep 27 18:09:31 1991 John Gilmore (gnu at cygnus.com)
299 * c-exp.y, m2-exp.y: Define more yysymbols that happen to be
300 "bss" rather than "data" symbols, but which still conflict.
303 * coffread.c (coff_symfile_read): Use xmalloc, not malloc.
304 * core.c (core_files_info): Shorten output.
305 * exec.c (exec_files_info): Ditto.
306 (build_section_table): Ignore zero-length sections.
307 * language.c, printcmd.c: Lint.
308 * language.h (get_frame_language): Declare.
309 * saber.suppress: update.

320 * nindy-tdep.c (nindy_frame_chain_valid): Use lookup_misc_func.
321 (Reported by Mark Peek <mark@imagen.com>.)
323 * solib.c (solib_map_sections): Relocate all sections, even
324 though only the text section's size is tracked. Mark ld_text
325 for eventual elimination as we generalize to N sections.
327 * infrun.c (wait_for_inferior): Don't check if the PC is in a
328 call_dummy if we were stopped by a random signal that is being
329 passed to the program. This produced wierd results when calling
330 functions in the inferior and signals (e.g. SIGALRM) were in use.
332 Tue Sep 24 18:05:30 1991 John Gilmore (gnu at cygnus.com)
334 * infrun.c (IN_SIGTRAMP): Not parenthesized properly.
335 Bugfix from Paul Eggert <eggert@twinsun.com>.
336 * tm-ultra3.h (IN_SIGTRAMP): Ditto.
337 * valprint.c (print_floating): Print 9 digits for IEEE floats.
340 Mon Sep 23 15:50:07 1991 John Gilmore (gnu at cygnus.com)

352 and restore the language string after giving help.
353 * valprint.c (typedef_print): Print typedef in C or M2.
354 * symtab.c (list_symbols): Use it.
355 * main.c (main): Avoid any output before (gdb) prompt when -q.
356 * language.c (set_language_command): Handle errors by restoring
357 the language string to its current state (fix from A. Beers).
358 * doc/gdbint.texinfo: Roll in information from README. Rearrange
359 "how to install" and "how to print the doc" stuff so it drops
361 * configure.in: Rename rtpc CPU to romp to match config.sub.
362 * README, WHATS.NEW, TODO: Update for gdb-4.1.
364 Fri Sep 20 17:39:14 1991 Roland H. Pesch (pesch at cygnus.com)
366 * doc/gdb.texinfo: Updates from ChangeLog. set/show write,
367 autoloading shared libs, copyright etc on GDB startup, clean up $_
368 and $__ index refs, set/show listsize and related updates to list
369 cmd. New host/target configs.
371 Fri Sep 20 15:46:00 1991 Roland H. Pesch (pesch at cygnus.com)
373 * doc/Makefile: generate aux version-no file doc/gdbVN.m4
374 from main Makefile.in version definition
375 doc/gdb.texinfo: use version recorded in doc/gdbVN.m4 for current
377 Makefile.in (setup-to-dist): generate doc/gdbVN.m4
379 * doc/gdb.texinfo: merge new language-switching and lang-specific
382 Fri Sep 20 15:00:57 1991 Per Bothner (bothner at cygnus.com)
384 * mcheck.c: Add __ONEFILE kludge to allow compilation by non-ANSI
385 compilers (which may lack stddef.h).
387 Fri Sep 20 13:29:42 1991 John Gilmore (gnu at cygnus.com)
389 * dbxread.c (read_dbx_symtab, process_one_symbol): N_FN and
390 N_WARNING are the same except for the N_EXT bit, so just use their
391 values alone, rather than OR-ing them with N_EXT.
393 Fri Sep 20 12:27:55 1991 Stu Grossman (grossman at cygnus.com)
395 * mipsread.c (parse_lines): Deal with negative extended line
398 * c-exp.y, m2-exp.y: #define yyerrflag and yynerrs to avoid
399 global symbol conflicts.
401 Fri Sep 20 02:28:15 1991 John Gilmore (gnu at cygnus.com)
403 * .gdbinit: Move 'set complaints' to top, so it runs even in
404 case we aren't debugging GDB.
405 * language.c (_initialize_language): Fix type check and range
406 check documentation strings.
407 * utils.c (!HAVE_VPRINTF): Define vfprintf as a function, so
408 language.c can use it. (Though language.c should really not be
409 handling warnings/errors the way it does, FIXME.)
410 * symtab.c (lookup_primitive_type): const lint.
412 Bugfix from Peter Schauer:
413 * source.c (lines_to_list): Make signed, to avoid comparison
414 going unsigned and complaining that -3 is too high for 21 lines.
415 * stack.c (lines_to_list): Ditto.
417 Thu Sep 19 23:33:41 1991 John Gilmore (gnu at cygnus.com)
419 * Makefile.in (HFILES): Add minimon.h.
420 (VERSION): Roll version number to 4.0.95.
421 (gdb.tar.Z, make-proto-gdb.dir, setup-to-dist, gdb-XXX.tar.Z):
422 New rules for building distributions. Normal distribution
423 is built by doing `make -f Makefile.in gdb.tar.Z' in the directory
424 one level up from here; it calls make-proto-gdb.dir to build a
425 directory `proto-gdb' which is an image of the release. The old
426 `gdb.tar.Z' rule still works too.
427 * config.sub, configure: Roll in latest from ..
429 Thu Sep 19 17:41:24 1991 Roland H. Pesch (pesch at cygnus.com)
431 * doc/gdbint.texinfo: Reorder contents; reorganize new-host,
432 new-target, and new-config chapters; fix minor typos; come closer
433 to usual GNU markup conventions for @file @samp @code @var.
435 Thu Sep 19 17:04:12 1991 Per Bothner (bothner at cygnus.com)
437 Patches from Peter Schauer <pes@regent.e-technik.tu-muenchen.de>:
438 * mipsread.c (parse_partial_symbols): Enter the name of all
439 structs/unions... into the psymtab so we can access them if the
440 symtab is not read in.
441 * mips-tdep.c: Remove some unneeded #includes.
442 * xconfig/dec3100: Add HAVE_STRSTR.
444 Thu Sep 19 15:14:23 1991 John Gilmore (gnu at cygnus.com)

456 Merge multiple-language support, and partial Modula-2 support,
457 from Andrew Beers <beers@cs.buffalo.edu>.
459 * i387-tdep.c: New file, consolidates most 80387 support,
460 and eliminates host dependency on double<->extended conversions.
461 * i386-xdep.c, symm-xdep.c: Remove most 387 support.
462 * xconfig/i386{sco,v,v-g,v32,v32-g}: Now need i387-tdep.o.
464 * symfile.c (allocate_symtab): New fn, consolidates the work
465 of allocating and initializing a new struct symtab. Set the
466 language of the symtab based on its filename extension.
467 * symfile.h: Declare it.
468 * mipsread.c (new_symtab): Use it. Minor formatting changes.
469 * dbxread.c (end_symtab): Use it.
471 * mipsread.c (parse_symbol, case stParam and stProc): Add #if 0'd
472 code for saving types of parameters with each function definition.
473 * dbxread.c (define_symbol, function and parameter cases): Ditto.
474 (read_dbx_symtab, case N_DEFD): Ignore.
475 (read_enum_type): Recognize FALSE/TRUE enum as Modula-2 BOOLEAN.
476 (read_range_type): Rename MAX_OF_TYPE to MAX_OF_C_TYPE, etc.
477 #if 0 out its uses, though, since they set a dead value.

519 * expression.h (enum exp_opcode): Add Modula-2 specific opcodes.
520 * expprint.c: Look up expression opcodes in language-specific

553 Tue Sep 17 08:37:41 1991 John Gilmore (gnu at cygint.cygnus.com)
555 Add Andrew Beers' changes for Modula-2 support. His ChangeLog
556 entries are enclosed herein. Not all of these changes
557 have been merged into the master GDB sources -- check the
558 ChangeLog above here for the merge log.
560 Mon Jun 3 17:05:45 EDT 1991
562 m2-exp.y Created. Tested outside of GDB for a few days. Proper
563 operators were added, C specific operators and tokens
564 removed. yylex() revamped to some extent. Still things
565 missing from the grammar, such as sets.
566 Tested for two weeks in GDB v3.5.
568 Tue Jun 11 17:23:48 EDT 1991
570 m2-exp.y Added boolean constants TRUE and FALSE to the grammar
571 so they are built-in. Sort of a hack.
573 Fri Jun 14 12:53:51 EDT 1991
575 m2-exp.y Added range checking for numeric constants. Any numeric
576 constant is assumed to be of builtin type INTEGER unless:
577 (1) it is octal or hexadecimal, in which case it is a
578 CARDINAL; (2) it is too big to fit into an INTEGER, in
579 which case it is a CARDINAL.
580 eval.c Added simple range checking for +, -, and * on integers.
581 Doesn't work very well for *, since 6 * 1,000,000,000 =
582 1,705,032,704, which fails the simple test of result >=
583 first_operand, no matter in what order the operands are.
585 Tue Jun 18 14:11:30 EDT 1991
587 Broke the parser into parts, one containing the C grammar and the other
588 containing code to be shared by all of the grammars.
590 The following files no longer exist:
595 The following files were added:
597 c-exp.y (The C grammar)
598 m2-exp.y (The Modula-2 grammar)
599 parser-code.c (Code that is shared by the above grammar)
603 Makefile.dist Changed to reflect the above dependencies. NOTE: It is
604 now necessary to use the Bison compiler compiler, since it
605 will generate function/variable prefixes other than yy.
607 Tue Jun 18 16:47:49 EDT 1991
609 symtab.[ch] Added the external variable working_lang, than holds the
610 value of the current working language.
611 Added the ennumerated type language_mode, with the values
612 language_auto and language_manual, the former meaning that
613 GDB sets working_lang as needed, and the latter meaning
614 that the value of working_lang is totally under user
616 symtab.[ch] Added the Modula-2 pervasive types INTEGER, CARDINAL,
617 REAL, BOOLEAN and CHAR. Also added the type codes
618 TYPE_CODE_BOOL and TYPE_CODE_CHAR.
619 utils.c Added set_language_command and show_language_command to
620 implement the GDB support commands "set language" and
622 expression.h A number of identifiers were added to the type exp_opcode
623 to facilitate Modula-2 builtin functions, integer
624 division, and array indexing.
626 Wed Jun 19 13:25:58 EDT 1991
628 language.h Added the macro STRICT_TYPE, which evaluates to non-zero
629 if the language specified by working_lang requires the use
630 of strict typing of expressions. Eventually, even this
631 will be able to be changed by the user.
632 Added the macro RANGE_CHECK, which evaluates to non-zero
633 if the language specified by working_lang requires the
634 checking of a value against the domain of its type.
635 Eventually, even this will be able to be changed by the
637 language.[ch] Predicates involving types (simple_type, ordered_type,
638 same_type, integral_type, numeric_type, character_type,
639 boolean_type, float_type) are added. These predicates are
640 based on the current value of working_lang, and are handy
643 Wed Jun 19 15:39:34 EDT 1991
645 eval.c Added the function type_array_rank which computes the rank
647 valarith.c Added the funtion value_bool, which when given a integer
648 value.h value (ie. struct value *) as an argument, it returns a
649 boolean value (ie. struct value *) true if that integer
650 is non-zero, and a boolean value false otherwise.
651 valprint.c Added cases for TYPE_CODE_BOOL, so Modula-2 BOOLEAN values
652 will print out properly.
654 Wed Jun 19 16:36:34 EDT 1991
656 valops.c Added the function value_capitalize, which returns it
657 value.h argument capitalized if its argument is a lowercase
658 letter, or the argument unchanged if its argument is not a
660 valarith.c Added the function range_check_p, which returns non-zero
661 value.h if its value argument is between the integral bounds upper
663 Added the function range_check_enum_p, which makes sure
664 that its value argument is a valid member of the domain of
666 Added the function range_check_range_p, which makes sure
667 its value argument lies between the upper and lower bounds
668 of its type argument, which must be a ranged type.
669 Added the function check_array_index, which range and type
670 checks an index of an array.
671 Added the function value_multi_subscript, which computes
672 array[idx1,idx2...idxN], given a value array and an array
673 of values representing indicies.
674 values.c Changed value_from_long to work with TYPE_CODE_CHAR and
675 unpack_long to work with TYPE_CODE_BOOL and
678 Wed Jun 19 18:04:08 EDT 1991
680 symtab.c Stored pervasive types in a structure and make
681 lookup_pervasive_type() a lookup function that was based
682 on working_lang. If lookup_pervasive_type() returned
683 non-zero, then that value was returned (a fix, since
684 before it simply wouldn't return the pervasive type.)
685 language.h Added the macro CAST_IS_CONVERSION, which evaluates to
686 non-zero if the language specified by working_lang means
687 "conversion" when it says "cast".
688 valops.c Added the function value_real_cast(), which performs a
689 value.h *cast*, not a *conversion*, which is what value_cast()
690 does when it can. In particular,
691 value_cast(<float_type>,4) = 4.0, while
692 value_real_cast(<float_type>,4) = some mess.
693 eval.c Modula-2 builtin functions implemented: ABS, CAP, CHR,
694 parser-code.c FLOAT, HIGH, MAX, MIN, ODD, ORD, TRUNC, and VAL.
695 expression.h Added macros MAX_OF_TYPE and MIN_OF_TYPE to work with MAX
696 and MIN on integral types. *NOTE*: These are currently
697 hardcoded to work only if there are 8 bits per storage
699 eval.c Made logical functions call value_bool to return a
700 properly typed boolean value, based on working_lang.
702 Thu Jun 20 11:55:27 EDT 1991
704 valprint.c Types now print out in a Modula-2 fashion. This works for
705 the cases when the type is printed out step-by-step, that
706 is, it doesn't work when the name of a structured type
707 (which includes the keyword "struct", etc.) is simply
709 FIXME: Perhaps this is bad. Parts of it seem to kludgey,
710 since type specifications in C and Modula-2 are very
711 different. The C printing of a type is very recursive,
712 whereas in Modula-2 it is generally very simple. C has
713 type prefixes and suffixes, which have no real analogue in
714 Modula-2. Maybe type_print() should call a language
715 specific type printer. This is also advantageous if we
716 compile GDB to exclude some of the languages. We'll just
717 leave those functions out.
719 Thu Jun 20 16:57:10 EDT 1991
721 dbxread.c When reading the complete symbol table in (via
722 psymtab_to_symtab()), the number and types of function
723 arguments are added to a function type. define_symbol()
724 calls add_param_to_type() to accomplish this.
725 Assumption: when we come across a function definition
726 (N_FUN symbol with an 'f' or 'F' in the name), its
727 arguments will appear before another function definition.
728 When a function is found, a pointer to its type is placed
729 in the global in_function_type. Changes that
730 add_param_to_type() makes are to this global.
731 valprint.c The type of a function now includes (for Modula-2) the
732 types of its parameters.
733 eval.c Type checking and a check for the proper number of
734 arguments is now done for function calls. Not sure of the
735 impact this has on C++ member function yet.
737 Thu Jun 20 19:58:48 EDT 1991
739 valprint.c Rewrote the type printer. Broke it into two language
740 specific parts, adding the functions type_print_m2() and
742 An unfortunate consequence is this: if you debugging a C
743 program in Modula-2 mode (why?), info types does not work
744 well with regular expressions, since the types are printed
745 out in Modula-2 terminology, but stored in C terminology.
746 language.[ch] Added the functions new_type_last(), type_keyword(), and
747 type_sep() to aid in the printing of typedefs.
748 symtab.c Made the printing of typedefs as language independent as
749 possible through calls to new_type_last(), type_keyword(),
752 Fri Jun 21 11:50:26 EDT 1991
754 dbxread.c Check all incoming ennumerated types. If it looks like
755 Modula-2's BOOLEAN type, then change the type_code of the
756 type to TYPE_CODE_BOOL so we can process it as a boolean
758 valprint.c Replaced some of the 0x%x with calls to sprintf and
759 hexformat() in val_print().
760 language.[ch] Added the function hex_to_string(), which converts its
761 integral argument to a hexadecimal number (format is
762 language based) and returns the result as a string.
764 Mon Jun 24 12:25:07 EDT 1991
766 valprint.c Some functions call type_print_1() directly, instead of
767 value.h using type_print(), so they can specify where (column) to
768 print things. Since type_print() takes care of language
769 dependence, that needs to be called first. Added a
770 parameter depth to type_print() (so it is now like
771 type_print_1). Changed type_print to type_print_at, and
772 made type_print a macro that passes a depth argument of
774 symmisc.c Changed all calls to type_print_1 to calls to
776 Makefile.dist Made it possible to build GDB for a specific set of
777 depend languages. Do this by passing a definition for the macro
778 LANGS to make. LANGS should be a string containing a
779 space-separated list of language names (ie. LANGS="c m2").
780 The default is to build all languages. Note that grammar
781 files must follow the naming convention of <lang>-exp.y.
782 gdb.lang This holds the current value of the LANGS macro. It is
783 examined every time make is called, and is updated if
785 eval.c Added #ifdef _LANG_<lang> to these files.
786 expread.c Still need to add them to dbxread.c and coffread.c.
794 Mon Jun 24 16:33:11 EDT 1991
796 language.[ch] Added the functions hexformat_pre() and
797 hex_to_string_pre(), which take a prefix argument to
798 include in the format string. Thus, hexformat_pre("08") will
799 return "0x08x" (if the working language is language_c).
800 Made hexformat() and hex_to_string() calls to the above
801 with "" as the prefix argument.
803 am29k-pinsn.c, arm-pinsn.c, breakpoint.c, convex-tdep.c, exec.c, core.c,
804 dbxread.c, i386-pinsn.c, i386-stub.c, i386-xdep.c, i960-pinsn.c,
805 infcmd.c, inflow.c, m68k-pinsn.c, m68k-stub.c, m88k-pinsn.c,
806 mips-pinsn.c, mips-tdep.c, ns32k-pinsn.c, printcmd.c, pyr-pinsn.c,
807 pyr-tdep.c, pyr-xdep.c, remote-vx.c, remote.c, solib.c, source.c,
808 stack.c, sun386-xdep.c, symfile.c, symm-xdep.c, symmisc.c, tahoe-pinsn.c,
809 valprint.c, vax-pinsn.c
811 Changed all occurences of 0x%[0-9]*l*x in printf format strings to
812 calls to hexformat() and hex_to_string(). Format strings without
813 the leading "0x" were ignored.
815 depend Updated to take the above into account.
818 Tue Jun 25 15:27:18 EDT 1991
820 symtab.h Added the types range_mode_t, range_check_t, type_mode_t,
821 and type_check_t to keep track of the current state of
822 range and type checking.
823 main.c Added the variables range_mode, range_check, type_mode,
824 and type_check to record the current state of range and
825 type checking. Added initialization code to main().
826 language.h Changed the macros STRICT_TYPE and RANGE_CHECK to examine
830 Tue Jun 25 17:57:08 EDT 1991
832 dbxread.c process_one_symbol() updates the variable (enum language)
833 source_lang based on the extension of the filename
834 contained in the N_SO sybmol that started this symtab.
835 When end_symtab() is called, the value of source_lang is
836 put into the language field.
837 stack.c select_frame() sets working_lang (and possibly type_check
838 and range_check) to the language field of the symtab
839 associated with the frame that is selected if working_mode
840 is language_auto. If working_mode is language_manual, a
841 warning is printed and working_lang is not set.
842 language.c Added the function set_type_range(), which sets the value of
843 type_check and range_check (if their modes call for
844 automatic setting) based on the current value of
845 working_lang. A non-zero argument will cause the current
846 settings to be output.
849 Wed Jun 26 14:51:40 EDT 1991
851 eval.c Added range checks on assignment.
852 m2-exp.y Added the grammar for sets to the language. Currently,
853 these do not do anything except print an error message.
855 Wed Jun 26 17:01:04 EDT 1991
857 m2-exp.y Added the ability for parse_number() to parse negative
858 numbers. A global flag is set upon encountering a unary
859 minus. This was done to make, for example, 1 parse as a
860 CARDINAL, and not as an integer, per Wirth's examples in
861 Programming in Modula-2 ed.4.
862 valprint.c Added support for "set radix 2" by then setting
863 output_format to 't'.
864 eval.c Implemented range checking on subrange types. Added calls
865 to range_check_range_p for BINOP_ASSIGN and BINOP_VAL.
866 Implemented MIN and MAX for ennumerated types. The
867 minimum value of an ennumerated type is defined by Wirth
868 as the first identifier, and the maximum as the last.
869 m2-exp.y Made octal numbers ending with "B" be characters and those
870 ending with "C" be numbers, per Wirth's book. (p. 34)
872 Thu Jun 27 14:11:52 EDT 1991
874 stack.c select_frame() now only sets working_lang, it does not
875 notify the user. If working_mode is language_manual, then
876 a warning is issued once.
877 main.c At the end of each call to execute_command(), working_lang
878 is checked against the local static (enum language)
879 current. If they differ and working_mode is
880 language_auto, the new settings of language, type and
881 range checking are printed out.
882 stack.c Modified frame_info() to include the language of the
883 current frame in the output of "info frame".
884 language.[ch] Added the function language_str() which returns the name
885 of the current language.
887 Fri Jun 28 15:33:14 EDT 1991
889 m2-exp.y Added the built-in procedures INC, INCL, DEC, and DECL to
890 the language. INCL and DECL currently cause an error,
891 since sets are not implemented yet. INC and DEC are
892 implemented as PREINCREMENT/PREDECREMENT with one
893 argument, and as ASSIGN_MODIFY with two arguments.
894 eval.c Added type checking to the above cases.
895 value.h Added not_lval_constant to the lval_type ennumerated type.
896 not_lval_constant means that the value is a constant
897 value; that is 3 or 'a' or TRUE, not as in a constant
898 identifier. This is used to help coerce numbers such as 3
899 to either signed or unsigned numbers.
900 valops.c Added the function value_coerce_constants() which coerces
901 constant integers as following: if one is a constant and
902 the other is not, the constant's type is set to the type
903 of the other argument. If both are constants and one is
904 signed, the other is converted to a signed constant.
906 Sat Jun 29 17:26:29 EDT 1991
908 valarith.c Added a better range checker. It now checks range
909 (successfully) on integral operations [+-] (signed and
910 unsigned) for any C sized type. Still does not work well
912 int_in_size() returns an integer that is coerced to fit into
913 specified number of bytes.
915 Mon Jul 1 13:04:14 EDT 1991
917 language.[ch] Added the function binop_result_type(), which returns the
918 builtin (struct type *) type that would be the result of a
919 binop on the two values V1 and V2.
921 Wed Jul 3 19:22:53 EDT 1991
923 source.c Extended source_info() to include the source language in
924 the output from "info source".
926 Fri Jul 5 13:48:52 EDT 1991
928 utils.c Moved the support functions for the GDB set/show commands
929 dealing with language into language.c.
930 language.c Added the function language_info(), which displays info
931 about the current working language, type and range check
932 settings. Called via the GDB command "info language".
933 Added an initialization routine _initialize_language(),
934 that sets defaults for the language, type and range
935 variables and sets up the new GDB commands.
936 main.c Language setup moved to language.c.
939 Mon Jul 8 10:10:22 EDT 1991
941 valarith.c Debugged the range checker for arithmetic. Still does not
942 work for multiplication very well.
944 Mon Jul 8 12:40:37 EDT 1991
946 language.[ch] Added the function value_true() which returns non-zero if
947 its argument represents a boolean true value.
948 breakpoint.c Changed breakpoint_cond_eval() to call value_true() to
949 check the truth of an expression.
951 Thu Jul 11 12:51:34 EDT 1991
953 language.[ch] Added the predicate structured_type(), which returns
954 non-zero if the argument is a structured type.
955 Added the predicate pointer_type(), which returns non-zero
956 if the argument is a pointer type.
957 eval.c Added the ability to do addition and substraction on
958 pointers and integers. This case simply bypasses the
961 Thu Jul 11 14:41:42 EDT 1991
964 Added the symbol N_DEFD (0x4a) which is a definition
965 module dependency that is used by the GNU Modula-2
966 compiler and the linker. It is not important to GDB,
967 except that [dbx|coff|mips]read.c should ignore these
970 Fri Jul 12 16:07:00 EDT 1991
972 valprint.c Changed the TYPE_LENGTH(type) >= 0 to TYPE_LENGTH(type) >
973 0 in val_print(). Also added statements to the else part
974 to coerce type (argument to val_print) to a pointer type
975 if it is an "array of unspecified length".
976 valops.c Added the function value_m2_string(), which returns a
977 (value) value which is a constant string, whose type is
978 (ARRAY [0..n] OF CHAR). The length field of the type
979 structure is set to zero, so it will be interpreted as an
980 "array of unspecified length".
981 stack.c Moved the language/frame mismatch check to
982 main.c:execute_command().
983 main.c The working language is recorded each time
984 execute_command() is executed. If working lang has
985 changed during its execution, then the new
986 language/type/range info is printed out for the user. If
987 the working language does not match the language of the
988 frame, a warning is issued.
990 Sat Jul 13 16:16:39 EDT 1991
992 eval.c Moved all the type-checking stuff for operators to
993 language.[ch] language.c. This is so we can keep language-specific
994 stuff (like for what type operators are defined) in
996 language.[ch] Added the function binop_type_check(), which checks to see
997 if its two (value) arguments are type-compatible with its
998 opcode argument. The opcode should represent an operation
999 involving an operator. Also added the macro function
1000 unop_type_check, which calls binop_type_check with a
1001 NULL second argument.
1002 expprint.c Added Modula-2 operators to the op_print_tab, so info
1003 expression.h break works correctly. Also added "op_string", which
1004 returns the string corresponding to the (enum exp_opcode)
1005 opcode that is its argument.
1008 Sat Jul 13 18:26:18 EDT 1991
1010 coffread.c Added code to record the type of function arguments with
1011 each paricular function. Code is very similar to that
1013 dbxread.c Moved add_param_to_type() to symtab.c
1014 symtab.[ch] Added function add_param_to_type() from dbxread.c
1016 *** NOTE: The above additions have not been tested.
1018 Mon Jul 15 12:50:47 EDT 1991
1020 langauge.[ch] Added the functions type_error and range_error, which work
1021 like error() except if the type/range mode is set to
1022 *_mode_warn, then they do not do a return_to_top_level(),
1023 but merely print a warning.
1024 Also changed [set|show]_[type|range]_command() to support
1025 the new "warn" feature.
1027 Thu Jul 18 17:50:54 EDT 1991
1029 mipsread.c Added code to record the type of function arguments with
1030 each particular function. Code is very similar to that
1033 *** NOTE: The above additions have not been tested.
1035 Fri Jul 19 11:19:10 EDT 1991
1037 defs.h Added macros MAX_OF_SIZE, MIN_OF_SIZE, UMAX_OF_SIZE, and
1038 UMIN_OF_SIZE, which when given a size of a numeric type,
1039 return the maximum and minimum value it can hold. UMAX...
1040 and UMIN... return the result for unsigned types.
1041 symtab.h Added the macros MAX_OF_TYPE and MIN_OF_TYPE to operate on
1042 struct types. They call above macros.
1043 dbxread.c Renamed the MAX and MIN_OF_TYPE macros to ..._OF_CTYPE to
1044 avoid a name conlict with the above.
1045 c-exp.y Added range checking on numeric constants in
1046 parse_number() for completeness.
1047 valarith.c Made binop_user_defined_p() and unop_user_defined_p()
1048 return 0 if working_lang is not language_c.
1050 Thu Aug 8 14:17:22 EDT 1991
1054 breakpoint.c Documentation strings of some commands changed to
1055 eliminate the references to the C language where
1058 Tue Aug 13 15:48:03 EDT 1991
1060 m2-exp.y Added qualified identifiers to the grammar. The semantics
1061 are slightly different from those of the GDB operator ::
1063 m2-exp.y Added a rule to each grammar of the form: start ::= exp |
1064 type_exp, where type_exp is any valid type expression.
1066 eval.c Added the opcode OP_TYPE, and an error case in eval.c.
1067 printcmd.c Modified ptype_command() so it actually parses the input
1068 (necessary for type expressions with scope qualifiers).
1069 Added the function ptype_eval() which expects an
1070 expression composed of one OP_TYPE element.
1071 *.[ch] Replaced all occurences of parse_c_expression with
1073 *.[ch] Replaced all occurences of parse_c_1 with parse_exp_1
1075 [End of ChangeLog entries from Andrew Beers for Modula-2 support.]
1077 Mon Sep 16 17:19:46 1991 John Gilmore (gnu at cygnus.com)
1079 Small fixes from Peter Schauer:
1081 * infrun.c (child_attach): Lint.
1082 * solib.c (find_solib): Handle shared libs version 2.
1084 Small fixes from David Wood:
1086 * xm-ultra3.h (SYS_SIGLIST_MISSING): Typo.
1090 * remote-vx.c: Move <stdio.h> to top, for FILE. Fix from
1091 John S <basrai%kanga.dnet@c3po.sm-alc.af.mil>.
1093 * utils.c (wrap_here): Avoid wrap action of fputs_filtered if
1094 chars_per_line is at maximum (user typed `set width 0'). Fix
1095 from Andreas Schwab <schwab@ls5.informatik.uni-dortmund.de>.
1097 Tue Sep 17 17:31:04 1991 Stu Grossman (grossman at cygnus.com)
1099 * coredep.c: include ptrace.h where necessary.
1100 * mipsread.c(parse_lines): fix unsigned char problem that was
1101 messing up line numbers on SGI's and possibly other MIPS based
1103 * infrun.c (child_create_inferior): use better test to check
1104 return val from setpgrp().
1105 * tm-irix3.h, xm-irix3.h, tconfig/irix3, xconfig/irix3: add these
1106 for sgi/irix support.
1108 Wed Sep 18 04:33:31 1991 Per Bothner (bothner at cygnus.com)
1110 * mipsread.c (parse_symbol): Put non-static procedures
1111 in the global block.
1113 Fri Sep 13 00:14:52 1991 John Gilmore (gnu at cygnus.com)
1115 Patch together `text_start' and `text_end' for 29K port.
1117 * exec.c (exec_command): If NEED_TEXT_START_END, define the
1118 variables and set them based on the exec file.
1119 * am29k-tdep.c: declare text_start.
1120 * valops.c (call_function_by_hand): declare text_end.
1122 * inferior.h: Eliminate CANNOT_EXECUTE_STACK in favor of
1123 defining CALL_DUMMY_LOCATION as BEFORE_TEXT_END. This is
1124 because machines that do this will also have to know to
1125 set NEED_TEXT_START_END. Besides, it was a redundant way to
1127 * tm-29k.h, tm-convex.h, tm-np1.h: Eliminate
1128 CANNOT_EXECUTE_STACK, define CALL_DUMMY_LOCATION and
1129 NEED_TEXT_START_END.
1131 Thu Sep 12 00:22:24 1991 John Gilmore (gnu at cygint.cygnus.com)
1133 AMD 29000 changes from David Wood <wood@david.ultra.nyu.edu>:
1135 * Makefile.in (CLIBS): Put XM_CLIBS and TM_CLIBS at end.
1136 Pass MUNCH_DEFINE to munch whenever we run it.
1137 * am29k-pinsn.c (print_insn): Handle NOP specially. Avoid %#x
1138 format string; use 0x%x instead.
1139 * am29k-tdep.c: Use DUMMY_SAVE_GREGS and RETURN_REGNUM.
1140 * ultra-xdep.c, xm-ultra.h: New files for Ultracomputer host system.
1141 * xm-rtbsd.h: New host support for RT/PC running BSD Unix.
1142 * inflow.c: Handle `short' process group IDs.
1143 * infptrace.c (fetch_register): Support CANNOT_FETCH_REGISTER,
1144 and check for ptrace errors.
1145 * coffread.c (SDB_REG_TO_REGNUM): Define if not already.
1146 (coff_symfile_init): Initialize text_bfd_scnum.
1147 (read_coff_symtab): Use it to find the text [and absolute?] sections.
1148 * ../config.sub: Add vendor nyu and os "sym[1-9]*".
1149 * configure.in: Add hosts rtpc-*-* and a29k-*-*.
1150 Merge target arm case with other "easy" cases. Add target
1151 cases a29k-*-none (rehack of am29k), a29k-*-kern (remote to
1152 Ultracomputer kernel), and a29k-*-sym1 (ultracomputer OS's user
1154 * minimon.h, remote-adapt.c, remote-mm.c: Add.
1155 * munch: Cope with RT/PC putting fns in data segment.
1156 Restore ability to override `nm' by specifying MUNCH_NM.
1157 * xconfig/rtbsd, xconfig/ultra3: New host systems.
1158 * tconfig/a29k: Rename from tconfig/am29k. Add remote-mm
1159 and remote-adapt. Remove encapsulated coff #define's (the
1160 support should go in BFD, and gdb shouldn't know or care).
1161 * tconfig/a29k-kern: Same, but for remote kernel debugging.
1162 * tconfig/ultra3: For debugging user processes on Ultra3/Sym1.
1163 * tm-29k.h: Update BADMAG (though it should go away).
1164 Allow the register definitions to be overridden in another
1165 tm-file. Fix SR_REGNUM. Add a mess of _REGNUM's. Separate
1166 RETURN_REGNUM from GR96_REGNUM and DUMMY_SAVE_GREGS from
1167 DUMMY_SAVE_GR96, for handling kernel calling conventions
1168 that use GR64+ rather than GR96+.
1169 * tm-ultra3.h: New file, for use on Ultra3 Unix as well as for
1170 remote debugging of Ultra3 kernel. Includes tm-29k.h and
1171 overrides various things.
1173 * remote-mm.c (mm_attach, mm_wait): Handle attach like
1174 child_attach does, making a clean stop in the newly attached
1176 * remote-eb.c: Lint.
1178 * coffread.c: Make coffread independent of any particular
1179 variant of COFF. Avoid #include-ing any particular one except
1180 internalcoff.h. BFD now passes key values for symbol reading
1181 as part of its coff_data structure (LINESZ, SYMESZ, AUXESZ,
1182 and the symbol masks and shifts); use them.
1183 Remove obsolete end_of_text_addr.
1185 * exec.c: Remove unused include files.
1187 Wed Sep 11 19:38:44 1991 John Gilmore (gnu at cygint.cygnus.com)
1189 * Makefile.in (documentation targets): Pass $(M4).
1190 Bugfix from eggert@twinsun.com (Paul Eggert).
1192 * stack.c (down_silently_command): Check for stack existence.
1194 Tue Sep 10 23:08:29 1991 John Gilmore (gnu at cygint.cygnus.com)
1196 * Makefile.in (VERSION): Update to 4.0.3.
1198 Tue Sep 10 09:19:29 1991 John Gilmore (gnu at cygint.cygnus.com)
1200 * core.c (core_file_command): Print frame at coredump with
1201 its level number, by calling print_stack_frame.
1202 * frame.h: Add selected_frame_level, print_stack_frame.
1203 * frame.h, stack.c: Remove print_sel_frame, print_selected_frame.
1204 * convex-tdep.c, convex-xdep.c, infcmd.c, inflow.c, infrun.c:
1205 Change print_sel_frame and print_selected_frame callers to
1208 * dbxread.c (read_ofile_symtab): Avoid empty else clause.
1209 * symfile.c (free_named_symtabs): Ditto.
1210 * main.c (main): wrap_here needs an arg.
1211 * solib.c (find_solib): Avoid memory access if _DYNAMIC is zero.
1212 (solib_add): Avoid noise.
1213 (solib_create_inferior_hook): Lint.
1214 (sharedlibrary_command): Move dont_repeat to here.
1215 * utils.c (error): Call wrap_here to force buffered output.
1217 Small patches from Peter Schauer:
1219 * coffread.c (start_symtab): Free any existing line_vector before
1221 (read_coff_symtab): Ditto for type_vector.
1223 * source.c (lines_to_list): New variable, replacing function.
1224 (all uses): Use as variable.
1225 (_initialize_source): Add 'set listsize' and 'show listsize'.
1226 * utils.c (lines_to_list): Remove function.
1227 * stack.c (print_frame_info): Use as variable.
1228 * defs.h (lines_to_list): Remove declaration.
1230 Mon Sep 9 13:45:57 1991 John Gilmore (gnu at cygint.cygnus.com)
1232 * breakpoint.c (insert_breakpoints): Restore warning about
1233 the program might be running in another process, but only for
1234 systems with this brain death (#ifdef ONE_PROCESS_WRITETEXT).
1235 * xm-hp300bsd.h, xm-mips.h, xm-vax.h: Define it.
1237 * utils.c (error): if error_pre_print is set, print the string
1239 * main.c (main, print_gnu_advertisement, print_gdb_version):
1240 Reformat legalese so it always prints, but acts as an "I'm here"
1241 message while symbols are being read. If any errors occur,
1242 print a few newlines to set off the message and start it at the
1243 left margin. Remove mention of "help" command, and don't yak
1244 about symbol reading.
1245 (catch_errors): Error string is now printed first in case of
1247 * command.c (undef_cmd_error, lookup_cmd): On undefined command,
1248 suggest the "help" command.
1250 * Makefile.in (VERSION): Set to 4.0.2.
1252 Thu Sep 5 23:49:48 1991 John Gilmore (gnu at cygint.cygnus.com)
1254 * .gdbinit: Remove useless "rr" command. Set complaints
1255 to 1 for people debugging gdb.
1257 * breakpoint.c, remote-vx.c: Reword strings printed by
1258 catch_errors callers.
1260 Wed Sep 4 11:07:50 1991 John Gilmore (gnu at cygint.cygnus.com)
1262 * WHATS.NEW: "history write -> history save". Doc "write on/off".
1263 (Fix from kenc@viewlogic.com.)
1265 Fix some infrastructure to be able to cope with host and target
1266 machines with different sized basic types (ints, ptrs, etc).
1267 (Idea from pierre@la.tce.com (Pierre Willard).)
1269 * values.c (value_from_longest): Rename from value_from_long.
1270 Handle pointer types as well as integers, so that targets with
1271 different pointer sizes from the host can be accomodated.
1272 * breakpoint.c, convex-tdep.c, eval.c, expprint.c, printcmd.c,
1273 valarith.c, valops.c, valprint.c, value.h, values.c: Rename
1274 uses of value_from_long to value_from_longest.
1275 * eval.c, findvar.c, printcmd.c, valarith.c, valops.c: Pass
1276 the correct pointer type to value_from_long{est}.
1278 * doc/gdb.texinfo ($_, $__): Describe types of these variables.
1280 * remote-vx.c: Remove obsolete code for calling functions via
1281 vxworks kludge interface (it referenced value_from_long).
1283 * valops.c (value_string): Find malloc with lookup_misc_func, not
1286 Tue Sep 3 18:37:46 1991 John Gilmore (gnu at cygint.cygnus.com)
1288 Make writing to files work properly. (Fixes to BFD are also needed.)
1290 * core.c (core_open): Open file ourselves, read or r/w, depending on
1291 write_files. Use bfd_fdopenr.
1292 * gdbcore.h (write_files): New variable.
1293 * exec.c (write_files): Define variable, add set&show for it.
1294 (exec_file_command): Use write_files to open for read or r/write.
1296 Make shared library reading happen automatically. These changes
1297 are mostly from Peter Schauer <pes@regent.e-technik.tu-muenchen.de>.
1299 * inferior.h (stop_soon_quietly): Add to exported variables.
1300 * infrun.c (child_create_inferior): call solib hook, if defined.
1301 (child_attach): call solib hook, if defined.
1302 * solib.c: Include inferior.h. Add from_tty to so_list as kludge.
1303 (find_solib): Use lookup_misc_func rather than hand-rolled.
1304 (symbol_add_stub): New stub for catch_errors.
1305 (solib_add): Avoid output if !from_tty. Catch errors rather
1306 than just calling symbol_file_add and bombing.
1307 (solib_create_inferior_hook): Interface with the target process
1308 to let it read and alloc shared libs, then figure out what it did.
1310 * core.c (validate_files): Fix typo, soften warning.
1311 (Fix from Hiroto Kagotani <kagotani@cs.titech.ac.jp>.)
1313 * utils.c (fputs_demangled): Avoid duplicate printing if
1314 demangling is off. (Fix from J.T. Conklin <jtc@cayenne.com>.)
1316 * infrun.c (proceed): Cast -1 to (CORE_ADDR) before comparing.
1317 (Fix from pierre@la.tce.com (Pierre Willard).)
1319 * main.c (catch_errors): Change argument to a char * from an int,
1320 since a char * can point to a struct full of glop, but an int
1321 is not guaranteed to be able to hold a pointer.
1322 * breakpoint.c (breakpoint_cond_eval, bpstat_stop_status,
1323 breakpoint_re_set_one, breakpoint_re_set): Adapt.
1324 * core.c (core_open, solib_add_stub): Adapt.
1325 * remote-vx.c (symbol_stub, add_symbol_stub, callers): Adapt.
1327 Wed Aug 28 18:18:05 1991 John Gilmore (gnu at cygint.cygnus.com)
1329 * Makefile.in: Update VERSION to 4.0.1. Evade GNU Make bug
1330 by adding .NOEXPORT target.
1332 Fri Aug 23 17:14:25 1991 John Gilmore (gnu at cygint.cygnus.com)
1336 * Makefile.in (VERSION): Roll to 4.0.
1337 (gdb.tar.Z): Make refcard.ps as well, for shipment.
1339 Fri Aug 23 14:07:09 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1341 * doc/gdb.texinfo: minor rewordings, crossref to ptype from print,
1344 * doc/Makefile, Makefile.in: generate "gdb-all.texi" rather than
1347 * doc/rdl-apps.texi: renamed from rdl-apps.texinfo
1349 * Makefile.in, doc/Makefile, doc/.Sanitize, doc/gdb.texinfo:
1350 reflect above name change
1352 * WHATS.NEW: correct pointer to refcard.
1354 * doc/gdb.texinfo: update New Features, Installing
1356 * doc/gdbint.texinfo: add short description of configure +template
1358 Fri Aug 23 11:46:08 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1360 * doc/gdb.texinfo: update, fix bugs in "Installing" appendix
1362 Fri Aug 23 01:02:00 1991 John Gilmore (gnu at cygint.cygnus.com)
1364 * Makefile.in: Add config.sub, make doc/rdl-apps.texinfo for
1365 tar file, add dependencies for referenced doc files.
1367 Thu Aug 22 22:17:06 1991 Stu Grossman (grossman at cygint.cygnus.com)
1369 * coffread.c, symfile.c, stack.c: saberized.
1371 Thu Aug 22 16:20:27 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1373 * doc/refcard.tex: permuted Essential Commands sec
1375 * doc/gdb.texinfo: new C++ chapter; revised installation appendix;
1377 set/show symbol-reloading
1378 default set complaints 0
1380 RET-repeat disabled after prompted long displays
1381 processID (attach) interpretation of 2nd GDB cmdline arg
1383 Thu Aug 22 14:05:47 1991 Stu Grossman (grossman at cygint.cygnus.com)
1385 * expread.y, coffread.c, dbxread.c, target.c, mem-break.c,
1386 cplus-dem.c, values.c, valprint.c, symfile.c, remote.c,
1387 breakpoint.c, main.c: lint.
1389 Thu Aug 22 02:02:26 1991 John Gilmore (gnu at cygint.cygnus.com)
1391 Install new configuration scheme for GDB and friends.
1393 * config.sub: Translate ordinary names to three-part names.
1394 * configure: Use three-part names internally.
1395 * configure.in: Translate three-part names to filenames.
1397 * README, WHATS.NEW: Update for gdb-4.0.
1398 * Makefile.in: Roll VERSION to 3.99.
1400 Wed Aug 21 18:21:09 1991 John Gilmore (gnu at cygint.cygnus.com)
1402 * infptrace.c (KERNEL_U_ADDR_BSD): Include a.out.gnu.h.
1403 * i960-tdep.c, m68k-tdep.c, sparc-tdep.c, tm-i960.h,
1404 tm-m68k.h, remote-nindy.c: Change ext_format_XXX structs
1405 to single structures rather than arrays; when passing
1406 their address, use &. This avoids trouble with bdead compilers.
1407 * mcheck.c: Don't include <stdlib.h>; just declare "void abort();"
1408 instead. This avoids portability headaches.
1409 * mips-tdep.c (mips_do_registers_info): Only print FP regs if
1411 * source.c (open_source_file): Avoid ANSI const bdeath by
1412 skipping declaration and then casting result value.
1413 * tm-hp300bsd.h: Clarify comment.
1414 * utils.c (strstr): Result is const char *; ANSI bdeath.
1415 * xm-hp300bsd.h: Define HOST_BYTE_ORDER. Redefine INT_MIN,
1416 since system include file defines it differently from "defs.h",
1417 though the two are equivalent for our purposes.
1418 * tconfig/hp300bsd: Add m68k-tdep.o.
1420 Tue Aug 20 16:01:11 1991 John Gilmore (gnu at cygint.cygnus.com)
1422 * tconfig/sun*4: Remove warnings about system assembler.
1424 Mon Aug 19 13:44:46 1991 John Gilmore (gnu at cygint.cygnus.com)
1426 * mcheck.c: Avoid warning about undeclared abort fn.
1427 * tm-sparc.h (PC_ADJUST): Avoid calling error() from this;
1428 it causes recursive calls to error() when used in cleanups.
1429 To do so requires that we make it a function, so we do.
1430 * sparc-tdep.c (sparc_pc_adjust): New implem of PC_ADJUST.
1431 * utils.c (do_cleanups): Remove the current cleanup from the
1432 chain *before* calling it, in case error() is called from it.
1433 The result won't be pretty, but won't be an infinite loop either.
1435 Mon Aug 19 00:41:04 1991 Michael Tiemann (tiemann at cygint.cygnus.com)
1437 * dbxread.c (read_struct_type): Grok anon structs for C++.
1438 (vb_name, vptr_name): Null terminate these strings.
1440 Fri Aug 16 08:31:03 1991 John Gilmore (gnu at cygint.cygnus.com)
1442 Minor bug fixes from BSD Net2 gdb:
1444 * blockframe.c (get_prev_frame_info): If FRAME_CHAIN_COMBINE
1445 returns 0, there is no previous frame.
1446 * breakpoint.c (commands_command): If !from_tty, don't call
1447 input_from_terminal_p().
1448 * dbxread.c (record_misc_function): Speed up slightly.
1449 (compare_psymbols): Ditto.
1450 * infcmd.c (do_registers_info): Take a second argument to
1451 determine whether to print float registers. "info registers"
1452 does not do so anymore. "info all-registers" does, now.
1453 * mips-tdep.c, pyr-tdep.c (xxx_do_registers_info): Take second
1455 * tm-mips.h, tm-pyr.h (DO_REGISTERS_INFO): Pass second arg.
1456 * inflow.c (initialize_inflow): Set tflags_ours correctly.
1460 * breakpoint.c (bpstat_do_actions): Use a cleanup to restore
1461 executing_breakpoint_commands if we are interrupted by error.
1462 * coffread.c (init_lineno): Avoid problem with zero-sized linetab
1463 versus malloc/free. From: john@labtam.labtam.oz.au (John Carey).
1464 * core.c (solib_add_stub, core_open): Call SOLIB_ADD inside a
1465 catch_errors() so we can setup the frame regardless of whether
1466 the shared libs work.
1467 * ieee-float.c (double_to_ieee_extended): Get exponent from
1468 right place in little-endian systems. From John Carey.
1470 Thu Aug 15 18:43:57 1991 John Gilmore (gnu at cygint.cygnus.com)
1472 * main.c: Remove unused terminating_signals and catch_termination().
1473 (long_options): Terminate with a zero element.
1474 [Bugfix from Atsuo Kawaguchi <atsuo@hark86.harl.hitachi.co.jp>.]
1475 (gdb_readline): Make call-compatible with readline.
1476 (init_signals): Improve comments re vfork vs. signal.
1478 * utils.c (prompt_for_continue): Use new gdb_readline().
1479 If we prompt for continuation, we don't let CR repeat the previous
1480 command, once we get back to a prompt. It's too easy to keep
1481 hitting CR, expecting "--more--" prompts, and have some long
1482 command start repeating on you.
1484 Tue Aug 13 16:17:56 1991 John Gilmore (gnu at cygint.cygnus.com)
1486 * blockframe.c (frameless_look_for_prologue): Speed up by
1487 calling SKIP_PROLOGUE_FRAMELESS_P if it's defined.
1488 * tm-sparc.h (SKIP_PROLOGUE, SKIP_PROLOGUE_FRAMELESS_P):
1489 Define two variants, one faster.
1490 * sparc-tdep.c (sparc_frame_chain): Use target_read_memory
1491 and return zero, rather than giving an error.
1492 (setup_arbitrary_frame): Initialize the PC in the new frame.
1493 (skip_prologue): Add a second arg saying whether we're just
1494 checking for a frameless function or not.
1496 * core.c (core_open, core_close, core_xfer_memory): Move
1497 section table pointers and bfd* into the target_ops.
1498 (core_open): Allow errors in shared lib reading, etc.
1499 (core_files_info): Describe shared library sections.
1501 * exec.c (exec_open, exec_close, exec_xfer_memory, xfer_memory,
1502 exec_files_info, set_section_command): Move section table
1503 pointers and bfd* into the target_ops.
1504 (add_to_section_table): Add BFD to section table.
1506 * target.c (target_xfer_memory, target_info): Pass target to
1507 xfer_memory and target_info functions.
1510 * gdbcore.h: Move struct section_table.
1511 * target.h: New home of struct section_table.
1513 * solib.c (solib_add): New argument is the target_ops whose
1514 section list is to be added to, if any. Reallocate the
1515 sections in that target to add any that come from shared libs.
1516 (throughout) so_sections renamed to sections.
1517 (solib_xfer_memory): Deleted.
1518 * tm-sunos.h (SOLIB_ADD): Add target argument.
1519 (SOLIB_XFER_MEMORY): Delete.
1521 * core.c, exec.c, inftarg.c, remote-eb.c, remote-nindy.c,
1522 remote-vx.c, remote.c, target.c, target.h: Remove add_syms vector
1523 from target_ops. It's the same on all targets. Add two section
1524 pointers to target_ops.
1526 * stack.c (find_relative_frame): Dump ancient algorithm for
1527 "down", just use handy "next" pointers.
1528 (frame_command): Don't error if there is no stack; let user
1531 * inflow.c (new_tty_prefork, new_tty): New prefork routine
1532 modifies static state in the parent process; new_tty itself
1533 runs in the child and modifies the child's file descriptors
1534 to match the saved static state.
1535 * infrun.c (child_create_inferior): Call new_tty_prefork,
1538 * infptrace.c (child_xfer_memory): Add ignored target arg.
1539 * remote-eb.c (eb_xfer_inferior_memory): ''
1540 * remote-nindy.c (nindy_xfer_inferior_memory): ''
1541 * remote-vx.c (vx_xfer_memory): ''
1542 * remote.c (remote_xfer_memory): ''. Rename from
1543 remote_xfer_inferior_memory.
1545 * main.c (main): Only try to attach "corefile" argument if
1546 it starts with a digit.
1548 * symfile.c (symbol_reloading): New "set/show" variable.
1549 (symbol_file_add): Shorten message about symbol reading.
1550 (add_symbol_file_command): Merge with add_syms_addr_command,
1551 since this should work on all targets now.
1552 (stop_whining): Default to zero, to shut up complaints
1553 about bad symbol tables on many systems.
1554 (free_named_symtabs): Just exit unless symbol_reloading.
1556 * xm-sun3os4.h, xm-sun4os4.h: Define BROKEN_LARGE_ALLOCA,
1557 and add comment explaining shared library screw.
1559 * source.c: #if defined => #ifdef.
1561 Thu Aug 8 12:23:19 1991 John Gilmore (gnu at cygint.cygnus.com)
1563 * doc/gdbint.texinfo: Improve doc on porting to new OS's.
1565 Tue Aug 6 17:16:15 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1567 * doc/rdl-apps.texinfo: provide default readline-appendix finder
1568 (doc/Makefile knows how to make one for local config)
1570 * Makefile.in: use doc/Makefile for doc targets
1572 * doc/Makefile: GDB documentation now has its own Makefile
1573 doc/refcard.tex: renamed from "gdbrc.tex"
1574 doc/.Sanitize: add Makefile; recognize renamed refcard.tex
1575 doc/gdbint.texinfo: add markup in "Cleanups" chapter
1578 Fri Aug 2 00:13:06 1991 John Gilmore (gnu at cygint.cygnus.com)
1580 * values.c (baseclass_addr): When reading target memory, use the
1581 length of the basetype, not the upper type. We've only malloc'd
1582 enough space for the basetype, leading to errors in free().
1584 * expprint.c (print_subexp): Print UNOP_MEMVAL of an OP_LONG that
1585 ends up as a function specially, since we know the actual type of
1586 the pointed-to address. This (somewhat) fixes display of
1587 expressions that include misc_function_vector names. Try `cond 1
1588 !strcmp("a","b")' then `i b'.
1590 * infrun.c: Move DO_DEFERRED_STORES from proceed() to resume().
1591 The child can be proceeded from inside wait_for_inferior in
1592 evaluating breakpoint conditions, and DO_DEFERRED_STORES was
1593 getting skipped in that case.
1595 * expprint.c (print_subexp): Use filtered output, since the
1596 subroutines we call use it, otherwise the output is horribly
1597 mangled, since output of wrappable stuff comes out late.
1599 * Makefile.in: Bump VERSION to 3.98.1
1601 * infrun.c (child_create_process): Use execlp to find the
1602 shell to exec our target program. This requires some fiddling
1603 with `environ' since there is no execlpe().
1605 Thu Aug 1 15:35:17 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
1607 * Makefile.in, doc/gdbrc.tex, doc/rc-* (new files):
1608 Minor rearrangement of refcard permits two new make targets--
1609 gdbrc.dvi DVI output for refcard, using CM fonts
1610 gdbrc.ps PostScript refcard, using PS fonts
1612 Wed Jul 31 16:46:21 1991 John Gilmore (gnu at cygint.cygnus.com)
1616 * TODO, Projects, WHATS.NEW, README: Update for gdb-3.98.
1617 * Makefile.in (gdb-all.texinfo): Avoid touching file if M4 dies.
1619 Wed Jul 31 16:35:58 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1621 * doc/gdb.texinfo: last changes for release.
1622 Minor typo and formatting fixes; incorporated most fixes remaining from
1623 filed mail commenting on earlier drafts.
1625 Added warnings: pipes don't work in run command;
1626 conditions are converse of assertions;
1627 step over fn without debug info goes to next fn;
1628 vars may have "wrong" values near fn entrance, exit
1630 Added example from Kingston on printing repeated nonadjacent values
1632 Added explicit mention that in Emacs gdb mode C-c and C-z are like
1633 shell mode for signals
1635 Renamed "Stepping and Continuing" to "Continuing and Stepping" so it
1636 doesn't sound so much like its parent "Stopping and Continuing"; also
1637 moved entries on continue to top of section, so they don't get lost.
1639 Improved installation directions in appendix, added manual formatting
1642 Tue Jul 30 17:26:39 1991 John Gilmore (gnu at cygint.cygnus.com)
1644 * configure.in: Remove xm.h and tm.h even if we aren't linking
1645 new ones, so "./configure sun4; ./configure none" does the right
1646 thing. Assume that alldeps.mak and depend are already built in
1647 srcdir, and avoid running "make" (particularly "make depend",
1648 which involves "gcc") from inside configure. Build Makefile
1649 directly rather than building Makefile.conf first.
1650 * configure: Regenerate with above changes.
1651 * Makefile.in: Use $(BISON) to find bison. Roll VERSION
1652 to 3.98. Revise gdb.tar.Z procedure to produce a file
1653 called gdb-$(VERSION).tar.Z but which unpacks into a
1654 directory called "gdb". Move non-source files out of
1655 $(SFILES_SUBDIR). Pretty up alldeps.mak with comments.
1656 (depend): Don't try to do "gcc expread.y".
1657 (expread.o): Update dependencies by hand.
1659 Mon Jul 29 15:21:09 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1662 Fixed a variety of small typos that prevented info from formatting
1663 cleanly; altered too-long heading for GPL Appendix, as discussed
1664 w/RMS; Changed date on cover to July 91.
1666 Fri Jul 26 13:20:02 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1669 (1) Applied some fixes due to comments from Larry Breed (easier ones
1670 through chapsec 5.2)
1671 (2) Eliminated use of @footnote---had my doubts about it anyways, and
1672 it's broken in latest texinfo
1673 (3) Introduced *some* use of [] for optional arguments, where
1674 explanation is not simpler by listing cmd w arg and cmd w/out arg
1675 separately. Still not using @deffn.
1676 (4) Dropped in GPL-2. NOTE: one of GPL-2 or texinfo is broken; a
1677 couple of headings are too long. Need patches to texinfo or revision
1680 * Partial update to README (which still needs work for this
1681 release!): (1) use of configure corrected for new script,
1682 (2) "make gdb.dvi" and "make gdb.info" mentioned.
1684 Wed Jul 24 06:44:02 1991 John Gilmore (gnu at cygint.cygnus.com)
1686 * symtab.c (lookup_symbol): Don't complain right off about
1687 no debug symbols; use the misc function vector first.
1688 (list_symbols): Use misc function vector to find symbols
1689 that don't have debug info, and print them.
1690 (find_pc_symtab): Temporarily avoid fatal() when psymtab
1691 PC range doesn't match symtab PC range, as it does on the
1692 MIPS because our symtab reading isn't perfect.
1694 * dbxread.c (dbx_symfile_read): Make warning about
1695 "no debug symbols" slightly nicer.
1697 * source.c (select_source_symtab): If "main" symbol exists,
1698 but decode_line_spec can't find line info, don't just return
1699 a zero; try other source symtabs or give an error.
1701 * mipsread.c (parse_partial_symbols): Sort the psymtabs by
1702 their low addresses first, then rip through fixing high addrs.
1704 * ns32k-opcode.h (sfsr): Bugfix from Rune Nerg}rd,
1705 <runene@ifi.uio.no>.
1706 (NS32K_SVC_IMMED_OPERANDS): Reverse the #ifndef.
1708 Tue Jul 23 18:52:43 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1710 * Minor, mostly mechanical, cleanup of doc subdir for clean
1711 makeinfo'ing and TeXing; also ensured gdb-all.texinfo (post-m4)
1712 and gdb.info (post- texinfo2 makeinfo) generated for distribution.
1714 Sun Jul 21 03:54:52 1991 John Gilmore (gnu at cygint.cygnus.com)
1716 Mostly MIPS and general symbol-reading fixups.
1718 * doc/gdbint.texinfo: Add documentation on symbol-reading
1721 * mipsread.c: Remove kludges around #include "ecoff.h".
1722 Remove redefinitions of a_magic, etc, no longer used.
1723 (parse_symbol, ): Convert "Internal:" printfs to complain()ts.
1724 Fix global overview comments to match symfile.c protocol.
1725 (mipscoff_new_init): Eliminate cur_hdr if we have one.
1726 (mipscoff_symfile_read): Eliminate unused code. Avoid
1727 sorting all the symtabs, when all we have read here is psymtabs.
1728 The symtabs are sorted as they are created anyway. Tell
1729 condense_misc_bunches whether we're mainline.
1730 (psymtab_to_symtab_1): Pass filename when recursing, to make
1731 stack trace more informative.
1732 (parse_partial_symbols): Assume cur_hdr as argument.
1733 (read_mips_symtab): Don't clobber cur_hdr, so it can be freed.
1734 Pass cur_hdr implicitly to parse_partial_symbols. Avoid checking
1735 the TYPE_NAME of char *, since that's done in symfile.c.
1736 (free_numargs, parse_symbol, add_symbol, add_block,
1737 shrink_linetable): Declare these fns void.
1738 (upgrade_type): Convert tree of if's to switch. Clean up
1739 bogus "off == 0" handling with a complaint. Avoid setting
1740 field bitpos and bitsize of array with lower and upper bounds.
1741 Check specified bitsize of elements against their actual type's
1742 bitsize, and complain if different. Complain about unknown
1744 (parse_fdr): Don't assume sizeof(char *) == sizeof (struct *).
1745 (psymtab_to_symtab_1): Print names of subsidiary files that
1746 are being read in. FIXME, we read far too many files. This code
1747 is not the problem, the problem is in parse_fdr where the psymtabs
1749 (cross_ref): Result should indicate that we used one aux entry
1750 normally, or two if we encountered a "next" entry. This used
1751 to leave the caller pointing at the wrong aux entry.
1752 (add_symbol): If overflowed cur_block, reallocate it larger,
1753 chase all pointers to it, and complain(), rather than clobber memory.
1754 (shrink_block): Use xrealloc rather than xmalloc-and-copy.
1755 (new_field): Only allocate one field initially, not two.
1756 Pull ++ out of macro argument. Simplify.
1757 (_initialize_mipsread): Avoid initialization of importd
1758 global_psymbols and static_psymbols.
1760 * symfile.c (psymtab_to_symtab): Depend on XXX_psymtab_to_symtab
1761 to properly set pst->symtab; avoid searching for it.
1762 (symfile_fns): Improve comments, add a FIXME.
1763 * dbxread.c: Update comments to reflect symfile protocol.
1764 (read_ofile_symtab, end_symtab): Return the symtab.
1765 (psymtab_to_symtab_1): Set pst->symtab.
1767 * coffread.c (coff_symfile_read): tell condense_misc_bunches
1768 whether we're mainline.
1770 * symfile.h (sym_fns): Remove unused sym_discard member.
1771 * coffread.c, mipsread.c, dbxread.c: Remove XXX_symfile_discard.
1773 * mtrace.c (mtrace): Take effect if mallwatch is set, even if
1774 the environment variable is not.
1775 * infcmd.c (finish_command): Use filtered printfs.
1776 * cplus-dem.c: Add struct tags to a few unnamed structs.
1777 * valops.c (value_coerce_array): Improve comments.
1778 * valprint.c (type_print_varspec_suffix): Print array size only
1779 if greater than zero.
1780 * m88k-tdep.c: Shift some lines left by one space, that had
1781 apparently been trashed at some point.
1782 * TODO: More things to do, a few got done.
1784 Thu Jul 18 22:46:05 1991 John Gilmore (gnu at cygint.cygnus.com)
1786 * symtab.h (LOC_EXTERNAL): Eliminate in favor of LOC_STATIC.
1787 (ldsymoff, ldsymlen, globals_offset, statics_offset): Improve
1789 * dbxread.c (read_dbx_symtab): LOC_EXTERNAL -> LOC_STATIC.
1790 * expread.y, findvar.c, symmisc.c: Ditto.
1791 * printcmd.c (address_info): Update printed forms of LOC_
1792 symbols. Elim LOC_EXTERNAL.
1793 (print_frame_args): Keep track of param stack offsets before
1794 re-looking up to find the local register param is kept in.
1796 * mipsread.c: Use <symconst.h> and <sym.h> rather than <syms.h>.
1797 Further integration of mipsread into gdb. Eliminate unused
1798 routines, duplicate declarations. Handle static symbols in
1799 psymtabs as well as external symbols. When reading symtabs,
1800 insert symbols into the correct block (global, static, or a local
1802 (read_mips_symtab, parse_partial_symbols): Don't pass useless
1804 (mipscoff_symfile_read): Don't call select_source_symtab.
1805 (parse_symbol): Use SYMBOL_VALUE_ADDRESS where appropriate,
1806 rather than SYMBOL_VALUE.
1807 (parse_external): Comment clobbering of top_stack.
1808 (parse_partial_symbols): Update comments. Allocate and parse
1809 static symbols as well as external symbols. FIXME, enum values
1810 are not handled in this pass, but should be. Inline new_psymbol.
1811 Use SYMBOL_VALUE_ADDRESS.
1812 (psymtab_to_symtab_1): Read symbols into global static block
1813 by default (until enter some function's local block context).
1814 (sort_blocks): Clean up STATIC_BLOCK as well as GLOBAL_BLOCK.
1815 (destroy_all_symtabs, new_psymbol): Eliminate, unused.
1817 * source.c (select_source_symtab): Select a source symtab
1818 from either the symtabs or, failing that, the psymtabs.
1819 (list_command): Update error message.
1820 (forward_search_command, reverse_search_command): Use getc, not
1821 fgetc, for speed. FIXME, add comment about buffers that die if
1822 overrun by long line.
1824 * values.c (unpack_field_as_long, modify_field): Avoid shifting
1825 by an entire word, which is not portable, if we have a 32-bit
1826 field. (Code in dbxread.c already turns such bitfields, if
1827 aligned, into ordinary ints, but fixing this will help for other
1828 symbol formats and for future changes.)
1829 * core.c (core_open): Handle ANSI const brain death.
1830 * utils.c (vprintf): Fix varargs typo.
1832 Sun Jul 14 00:42:53 1991 John Gilmore (gnu at cygint.cygnus.com)
1834 * findvar.c (find_var_value): Handle &function better.
1835 * TODO: Document work needed on &fn and &array.
1836 * printcmd.c (print_address_symbolic): New arg is the prefix
1837 to print if a name is printed.
1838 (print_address_demangle): Honor "set print address" now.
1839 Use new arg above to improve spacing of output.
1840 * valprint.c (val_print): When printing function pointers,
1841 print symbolic form too.
1842 * breakpoint.c (breakpoint_1): Use new print_address_symbolic.
1844 Mon Jul 8 19:02:46 1991 John Gilmore (gnu at cygint.cygnus.com)
1846 * core.c (memory_error): Reword error msg to mislead less.
1848 * mips-pinsn.c (print_insn_arg 'd'): Print $ with reg name.
1850 * mipsread.c (read_mips_symtab, read_the_mips_symtab,
1851 parse_partial_symbols): Use newer BFD internals (external_filehdr
1852 and external_aouthdr), byte-swap the fields that we care about
1853 before using them, and make the file header data local to
1854 read_the_mips_symtab rather than global.
1856 Sat Jul 6 01:34:15 1991 John Gilmore (gnu at cygint.cygnus.com)
1858 * ns32k-opcode.h (movmw, movmd): Fix opcodes. Bug fix
1859 from Rune Nerg}rd <runene@ifi.uio.no> on 5 Jul 1991.
1861 * main.c (command_line_input): Flush stdout and stderr
1862 before every call to readline. This reportedly fixes a bug
1863 that comes up in Sys V running emacs-gdb and/or xxgdb,
1864 when stdin/out are pipes or sockets.
1866 Thu Jul 4 14:47:06 1991 John Gilmore (gnu at cygint.cygnus.com)
1868 * configure.in, Makefile.in: Avoid rebuilding "depend" as much.
1869 Avoid declaring Makefile dependencies, because GNU Make stupidly
1870 tries to update it if we do.
1872 * coffread.c: Revise for minor changes to bfd internal coff
1875 * configure: If -template= is given a relative path, make it
1876 absolute before recurring in subdirectories.
1878 * configure, configure.in, Makefile.in: Install "configure" script
1879 as replacement for config.gdb.
1880 * config.gdb, Makefile.dist, Makefile.sdir: Remove
1881 * README: Update for configure, mostly. FIXME.
1883 * Add dec3100 as equivalent to littlemips. Indicate in all host &
1884 target config files that they are for the host. When the lines
1885 get copied into the Makefile, this makes it more obvious what's
1888 Mon Jun 24 23:49:07 1991 John Gilmore (gnu at cygint.cygnus.com)
1890 * sparc-opcode.h (trap opcodes): Avoid leading spaces or
1891 tabs, which end up in the disassembler output inadvertently.
1893 Wed May 29 23:01:03 1991 John Gilmore (gnu at cygint.cygnus.com)
1895 Make it compile cleanly in an ANSI GCC2 environment.
1897 * blockframe.c: <stdio.h>
1898 * cplus-dem.c: free takes a void *, ifdef __STDC__
1899 * dbxread.c (read_huge_number): avoid gcc2 bug hoisting calc of
1901 * defs.h (alloca): Avoid doing anything if alloca already def'd.
1902 * stddef.h, stdlib.h: Remove these files.
1903 * symtab.c: Avoid declaring qsort, close.
1904 * symfile.c: Avoid declaring close.
1905 * utils.c (vprintf): Declare "ap" arg as proper va_alist.
1906 * sparc-tdep.c: Avoid including lots of Sun-host-specific files.
1908 Assorted other changes.
1909 * dbxread.c: include "libaout.h", not "liba.out.h".
1910 * printcmd.c (print_frame_args): Set recurse properly for
1911 indentation of struct and array parameters.
1912 * valops.c (value_cast): Allow cast to void.
1913 * infrun.c (resume): If NO_SINGLE_STEP, call machine dependent
1914 single_step() in a target-independent fashion.
1915 * sparc-tdep.c (single_step): Don't call ptrace ourselves, just
1916 set up to be ready to continue. This makes us target independent.
1917 * infptrace.c (child_resume): Remove call to single_step; now
1918 can single step a SPARC target of any kind.
1920 Wed May 22 18:18:24 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
1922 * Makefile.dist, doc/gdb.texinfo, doc/*-m4.texinfo: split up GDB
1923 docn into separate sections---basically chapters, plus two loose
1924 pieces that can be configured to go in different places. This
1925 allows GNU m4 to preprocess the manual without coredumping.
1927 * Makefile.dist: tell TeX where to find texinfo.
1929 Mon May 20 12:15:04 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
1931 * Makefile.dist, doc/gdb.texinfo: respectively create, and use,
1932 the new target "rdl-apps.texinfo" which captures the Makefile
1933 variable that records where to find the Readline libraries.
1935 Sun May 19 05:36:59 1991 John Gilmore (gnu at cygint.cygnus.com)
1937 * tahoe-pinsn.c: #include "tahoe-opcode.h", not "opcode.h".
1938 * tm-tahoe.h (FIX_CALL_DUMMY): Ignore more parameters.
1939 * defs.h (const, volatile): Only define if not already defined.
1940 * Makefile.dist (gdb.tar.Z): Create doc subdir w/out CVS/RCS crud.
1942 * README: Update for release 3.95.
1943 * config.gdb: Don't create readline dir in subdir builds.
1944 * main.c: Include with "..." form for non-system include files,
1945 so "gcc -MM" for "make depend" works.
1946 Include readline files with "...h" rather than <readline/...h>.
1947 * mipsread.c: Include "ecoff.h" rather than "intel-coff.h".
1949 * coffread.c: Undo minor damage done by Rich Pixley. Use
1950 different internal and external representations of COFF
1951 data structures. Use new BFD routines for swapping them in and
1953 * symfile.c (free_named_symtabs): Avoid freeing file names that
1954 are null or empty. Old i960 tools seem to produce files that
1955 claim to have empty names, causing each successive file read
1956 to blow away the previous one.
1957 * sparc-xdep.c (deferred_stores): Repair minor damage by Rich.
1958 Move deferred_stores to top of file, but don't separate its
1959 #define's from its variable. Add commentary.
1960 * Makefile.dist: Fix Rich damage; undo "configure" changes in
1961 favor of keeping the (working) config.gdb. Move readline
1964 Fri May 17 12:49:56 1991 Per Bothner (via gnu at cygint.cygnus.com)
1966 * dbxread.c (read_struct_type): Try to handle g++ version 1 MI
1968 * infptrace.c (fetch_registers): no result, since now void.
1969 * tconfig/news: target depends on m68k-tdep too.
1971 Fri May 17 14:40:14 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
1973 * Makefile.dist: added readline/inc-*.texinfo to dependencies for
1976 * readline/inc-history.texinfo, readline/inc-readline.texinfo:
1977 applied various small fixes due to or inspired by RMS comments
1979 * doc/gdb.texinfo: finished using all RMS comments, save those for
1980 appendices on readline and cmd history (which are in other source
1983 Thu May 16 18:06:05 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
1985 * doc/gdb.texinfo: (1) Updated w/ref to RMS comments through
1986 chapter 9; (2) documented 'break' command's menu mode for
1987 overloaded names, in response to hgs problem report C++ p-31
1989 Wed May 15 11:02:48 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
1991 * doc/gdb.texinfo: (1) better introductory example; (2) more
1992 consistent use of @code, @samp, @file, @kbd throughout; small
1993 cleanups to first three nodes; (3) new "Contributors" node;
1994 (4) Appendix, Renamed Commands; (5) divert specialized startup
1995 instructions to "Targets" chapter for generic manuals, while
1996 leaving them up front for manuals specific to specialized
1997 environments; (6) apply fixes from RMS comments through chapter 4.
1999 * pretex.m4: modify explanatory text slightly (and redefine
2000 "regexp") to keep GNU m4 from complaining. (It still crashes
2001 later, but one step at a time...)

2005 * readline/readline.c (update_line): Avoid dereferencing a pointer
2006 before comparing it to its bounds. Saber caught this.

2012 * Makefile.dist: put gdb.dvi stuff (updated to use M4 preprocessor
2013 stuff for config manual) here where it counts; updated
2014 to use new subdir structure (gdb/doc/).
2016 * Makefile: generated from above via
2020 * gdbint.texinfo: added instructions on generating gdb.info* files
2021 locally for release. These are ordinary info
2022 files, formatted from gdb.texinfo (via gdb-all.texinfo, see
2023 Makefile)---but due to use of texinfo 2, can't count on makeinfo
2024 to generate these, so we distribute them already formatted.
2026 * gdb.texinfo: included full Info node and menu crud (as generated
2027 by C-u M-x texinfo-master-menu using the texinfo-2 elisp code).
2029 * Makefile: updated "gdb.dvi" target to use M4 preprocessor;
2030 put in comments-for-future gdb.info target (one day makeinfo will
2033 Tue May 14 13:51:36 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)
2035 * gdb.texinfo: Updated to include new or old undocumented
2036 commands, at least the following (perhaps some others I forgot to
2037 record): info f, info float, info path, info program, info s, info
2038 set, info source, info terminal, info types, info user, set/show
2040 Also covered all recent GDB command renames for v4.

2044 * mipsread.c: Rather than keeping count of how many symtabs
2045 and psymtabs we have, for sorting purposes, count them when

2072 * remote.c: Remove decls of memory_insert_breakpoint
2073 and memory_remove_breakpoint, no longer used. (Suggestion of
2076 * Makefile.dist: use ${subdir} in paths of BFD and LIBIBERTY,
2077 to make it easier to interface to "configure"'d libraries.
2079 Fri May 3 13:10:01 PDT 1991 Roland Pesch (pesch at fowanton.cygnus.com)
2081 * valprint.c: introduce "set p", "set pr", "show p" and "show pr" as

2473 before returning locals or slocals.
2475 * i386-tdep.c (i386_follow_jump): Do not add data16 to pos in
2476 call to codestream_seek; add one to pos if (and only if)
2477 we are dealing with a jump with data16 == 1 (i.e. 0x66, 0xe9).
2479 Mon Apr 15 12:04:32 1991 Jim Kingdon (kingdon at cygint.cygnus.com)
2481 * valops.c (call_function_by_hand): Put dummy1 in target order

2507 tm-sun3.h: Define TARGET_SUN3.
2509 * utils.c: Use CPLUS_MARKER not '$'.
2511 * cplus-dem.c: Use CPLUS_MARKER not '$'. If CPLUS_MARKER isn't
2512 defined, define it to '$'.
2514 * arm-opcode.h: New file (same contents as before; it had
2515 just been left out of the distribution for a long time).
2517 * tm-68k.h: Put declaration of ext_format_68881 outside the macros.
2519 * main.c: New HAVE_SIGSETMASK #ifdefs.
2521 * coffread.c (read_coff_symtab): Check for "LF%" with all the

2536 * i386-pinsn.c (OP_E): Change %d to 0x%x for consistency.
2538 * putenv.c: New file
2539 Makefile.dist: Add it to $(OBS).
2541 * mipsread.c [!CMUCS]: #include <syms.h>.
2543 * mips-xdep.c (fetch_core_registers): #if 0 out the whole function.
2545 * Move read_memory_nobpt from mem-break.c to breakpoint.c.

2549 * utils.c (_initialize_utils): Rename "set demangle" to
2550 "set print demangle", "set asm-demangle" to "set print
2551 asm-demangle" and "set sevenbit-strings" to "set print

2557 * main.c (initialize_main): Rename "set caution" to
2560 * values.c (_initialize_values): Remove "info history" alias

2585 * inftarg.c (child_open), remote-vx{,.68}.c (vx_proc_open):
2586 New function to give correct error message.
2588 Thu Apr 11 17:19:41 1991 Jim Kingdon (kingdon at cygint.cygnus.com)
2590 * target.h: Add to_doc and target_preopen.
2591 target.c: Add target_preopen and target_command.
2593 (add_target): Call add_cmd and mess with targetlist->doc.
2594 core.c, exec.c, remote-eb.c, remote-nindy.c, remote-vx.c,
2595 remote-vx.68.c, inftarg.c, remote.c: Add doc field to target struct.
2596 Call target_preopen from open routine.
2598 * main.c: Rename editing_info to show_commands.
2599 (_initialize_main): Rename "info editing" to "show commands".
2601 * source.c: Rename directories_info to show_directories.
2602 (_initialize_values): Rename "info directories" to "show directories".

2612 (_initialize_symfile, add_syms_addr_command):
2613 Rename add-syms to add-symbol-file.
2615 Thu Apr 18 18:08:30 1991 John Gilmore (gnu at cygint.cygnus.com)
2617 * symfile.h (free_named_symtabs): Rename from free_named_symtab.
2618 * symfile.c (clear_symtab_users_once, cashier_psymtab,
2619 free_named_symtabs): Move these routines from symmisc.c.
2620 * symmisc.c (same): same.
2621 (free_symtab): Make non-static.
2622 * symtab.h (free_symtab): Declare as exported void fn now.
2623 * dbxread.c (end_symtab, end_psymtab): Change comments.
2624 (initialize_dbxread): Call dbx_new_init() in case the first
2625 command is add-symbols.
2626 * target.c (dummy_target): Permit add_syms_addr_command.
2628 Sat Apr 13 14:46:07 1991 John Gilmore (gnu at cygint.cygnus.com)
2630 Permit symbols to be superseded when new symbol files have
2631 been read in, particularly for VxWorks.
2633 * dbxread.c (read_dbx_symtab): Allow N_SOL to cleanly take us back
2634 to the main file, as well as to include files. Also, put global
2635 functions into the global psymtab, to make "i fun" work.
2636 (end_psymtab): Free named symtabs and psymtabs for a file, once a
2637 new psymtab for it has been read.
2638 * coffread.c (end_psymtab): Free named symtabs and psymtabs for
2639 a file, once a new symtab has been read for it.
2640 * mipsread.c: FIXME. We need to do the same for MIPS, but it
2641 looks harder to determine the top-level block before it's been
2642 queued to the psymtab list.
2644 * symfile.c (symbol_file_add): Use filtered printing and wrap it.
2645 If we have wiped out any old symbol tables, clean up at end of
2647 (symbol_file_command): Don't reference symfile_fns if it's zero.
2649 * symtab.h (GLOBAL_BLOCK, STATIC_BLOCK, FIRST_LOCAL_BLOCK): New
2650 defines for the blocks of a blockvector that contain global and
2651 file-static symbols and the first of the smaller scope contours.
2652 * symtab.c (lookup_symbol, find_pc_symtab, find_pc_line,
2653 decode_line_1, make_symbol_completion_list): Use the above.
2654 * coffread.c (end_symtab, patch_opaque_types): Ditto.
2655 * dbxread.c (end_symtab): Ditto.
2656 * expread.y (block): Ditto.
2657 * mipsread.c (throughout): Ditto.
2658 * symmisc.c (free_named_symtabs): Ditto.
2660 * symtab.c (list_symbols): Process the first symbol of the
2661 static psymbols list.
2662 (types_info): Restore this function from its untimely #if 0.
2663 It's not perfect, but it is better than nothing.
2664 (_initialize_symtab): Restore "info types".
2666 Thu Apr 11 05:23:19 1991 John Gilmore (gnu at cygint.cygnus.com)
2668 * m68k-stub.c: Remote stub for 680x0's, created from
2669 rem-m68k.shar (which is removed).
2670 * nindy-share/{Makefile,Onindy.c,blout.h,env.h,nindy.c,ttyflush.c}:
2671 Remove RCS log stuff now that we use CVS and it blows our diffs.
2673 Wed Apr 10 14:18:06 1991 John Gilmore (gnu at cygint.cygnus.com)
2675 * symmisc.c (free_named_symtab): Make it work, in its current
2676 kludgy fashion. Change result to indicate if we blew away bkpts.
2677 * dbxread.c (end_symtab): Accumulate result from
2678 free_named_symtab and print warning if we blew user's state.
2679 * symfile.h: free_named_symtab now returns an int.
2681 Mon Apr 8 23:57:43 1991 John Gilmore (gnu at cygint.cygnus.com)
2683 * dbxread.c (dbx_symfile_read): Initialize psymbol list if this
2684 is the first symbol read, even if not mainline.
2685 (dbx_psymtab_to_symtab): symfile might be zero, cope.
2686 * exec.c (exec_ops): Add_syms_addr is valid in our tvec.
2687 (set_section_command): New command ("section xxx yyy" -- should
2688 be renamed to "set section xxx yyy" FIXME) which sets the
2689 base address of a section of the exec file, overriding the
2690 virtual address that BFD reports.
2692 Fri Apr 5 17:14:39 1991 John Gilmore (gnu at cygint.cygnus.com)
2694 * exec.c: Add add_syms_addr_command to exec_ops, so you can
2695 load symbols at any address while examining an exec file.
2697 Thu Apr 4 10:09:35 1991 John Gilmore (gnu at cygint.cygnus.com)
2699 * tm-i386v.h (FLOAT_INFO): Don't define it, since the code
2700 for printing the float info is host-dependent, not
2701 target-dependent. FIXME.
2702 * i386-pinsn.c: Move #includes to top, remove useless ones.
2703 * i386-tdep.c: Don't bother including <.../reg.h> since we
2704 don't use it (and it doesn't exist on host systems).
2706 * ieee-float.c (ieee_extended_to_double): Convert NaN to Inf.
2707 Convert negative numbers properly.
2708 (ieee_test): Make numbers really random; fix format arg.
2710 * infcmd.c (attach_command, detach_command): Don't repeat on CR.
2711 * core.c (core_detach): Unpush core_ops, which might not be on
2712 top. We used to just pop the top, which broke things. Don't
2713 need dont_repeat() any more.
2714 (core_file_command): Psst! Don't repeat it.
2715 * remote-nindy.c (nindy_detach): Don't need dont_repeat() now.
2716 * expprint.c (print_subexp): Avoid switch fallthru on
2717 BINOP_ASSIGN_MODIFY, so we can print += and such.
2718 * frame.h: Fix typo.
2719 * inflow.c (kill_command): After killing inferior, print our
2720 current frame in the core file, if we have one.
2721 (generic_mourn_inferior): When inferior dies, either select
2722 the current frame (in the new target, e.g. core file), or
2723 set both the current and selected frames to NULL.
2725 Changes from Peter Schauer.
2727 * infptrace.c: Avoid <sys/ptrace.h> on USG.
2729 * Make all file names fit in 14 characters (sigh and damn!):
2730 mv hp300hpux-xdep.c hp300ux-xdep.c
2731 mv symmetry-xdep.c symm-xdep.c
2732 mv symmetry-tdep.c symm-tdep.c
2733 mv convex-opcode.h convx-opcode.h
2734 mv tm-vxworks960.h tm-vx960.h
2735 mv tm-vxworks68.h tm-vx68.h
2736 mv Makefile.srcdir Makefile.sdir
2737 mv gdb-int.texinfo gdbint.texinfo
2738 mv remote-sa.m68k.shar rem-m68k.shar
2739 mv remote-multi.shar rem-multi.shar
2740 * Makefile.dist, README, config.gdb, convex-pinsn.c,
2741 tconfig/symmetry, tconfig/vxworks960, tconfig/vxworks68,
2742 xconfig/hp300hpux, xconfig/symmetry: Change names to shorter
2745 * command.c (user_info_1, user_info): New command for listing
2746 the user-defined commands.
2748 Wed Apr 3 15:00:26 1991 John Gilmore (gnu at cygint.cygnus.com)
2750 * dbxread.c (really_free_pendings): Clear file_symbols
2751 and global_symbols after freeing them; otherwise, running
2752 this function twice (if it appears twice on the cleanup
2753 chain), we try to free things twice.
2755 * dbxread.c (read_dbx_symtab): Calculate end_of_text_addr
2756 based on text_addr (the address of text in core), not on addr (the
2757 offset between text in the .o file and in core). This change
2758 is from Peter Schauer.
2760 * main.c: Define ALL_CLEANUPS as a cast of zero.
2761 (return_to_top_level): Use it.
2762 (main): Do all cleanups after each command run as part
2763 of the gdb startup sequence. Also do all cleanups before
2764 entering the command loop, and every time we exit the command
2765 loop and reenter. Before, the cleanups from the startup sequence
2766 were being left undone until the first error!
2767 (command_loop): Rename do_nothing cleanup to command_loop_marker
2768 so we can see it easily when examining the cleanup chain.
2769 (init_signals): Add another do_nothing for signal handling.
2770 (quit_command): Only try to kill target if it has execution.
2771 Problems in the target stack got us into a state where
2772 inferior_pid was nonzero but none of the targets had execution.
2773 In this state you couldn't exit gdb.
2775 * dbxread.c: Two changes from Peter Schauer.
2776 (echo_command): Fflush output after an echo command.
2777 (show_history): Pass all args to cmd_show_list.
2779 * utils.c (init_malloc): Call mtrace to turn on tracing
2780 if the environment variable MALLOC_TRACE is set to a file name.
2781 * mtrace.c: Add source file which provides a log of every malloc,
2782 free, and realloc to a trace file.
2783 * mtrace.awk: Add source file which analyzes the trace file.
2784 * Makefile.dist (GNU_MALLOC, MALLOCSRC): Add mtrace.{c,o,awk}.
2785 (VERSION): Roll to 3.94.3.
2787 * breakpoint.c (breakpoint_1): Add a space to "i watch" output.
2788 (check_duplicates): Don't bother with watchpoints.
2789 (set_raw_breakpoint): Comment about danger of this routine.
2790 (watch_command): Parse and eval all args before calling
2793 * solib.c (find_solib): Avoid error in referencing memory to
2794 see if any more shared libraries have been added. This is
2795 particularly useful if the target has terminated. Bug reported
2798 Changes from Peter Schauer <pesrem@regent.e-technik.tu-muenchen.de>
2799 in bringing up 3.94.2 on the Sun-3.
2801 * Makefile.dist: Include CFLAGS in rule for cplus-dem.o.
2802 * breakpoint.c (enable_breakpoint): Check for valid watchpoint
2803 expression (in scope) before reenabling watchpoint.
2804 * signame.c (init_sigs): Add missing declaration of i, fix
2805 sys_siglist declaration.
2806 * source.c (list_command): Fixed range computation to use
2808 * stack.c (backtrace_command): Do not allow command if target has
2809 no stack, print informative error message.
2810 * target.c (target_command): Do not write into command line
2811 because this fails if the target command is used in a user defined
2812 command. [This change was enhanced by gnu to support any-
2813 unique-prefix matching on target names.]
2814 * valops.c (value_struct_elt): Avoid infinite loop on an
2815 erroneous attempt to print the member of function (try p main.p).
2817 Mon Apr 1 17:05:45 1991 John Gilmore (gnu at cygint.cygnus.com)
2819 * expread.y (name_no_typename): Avoid reduce/reduce errors
2820 caused by ambiguity in handling NAME_OR_INT and NAME_OR_UINT.
2821 Since the GDB parser really doesn't use name_no_typename in a
2822 name-only context, the parser can't tell the diff between
2823 names and numbers here. Avoid allowing a name_no_typename
2824 to be a NAME_OR_*INT to resolve the conflict.
2826 Sun Mar 31 20:12:07 1991 John Gilmore (gnu at cygint.cygnus.com)
2828 Bugfixes from Mark Fox (markf@wrs.com) (test=testField.c):
2830 * valprint.c (val_print_fields): bitfield printing didn't handle
2831 byte order. Indirect through a few more fns to cope.
2833 * values.c (modify_field): also cope with byte order.
2835 Sat Mar 23 10:02:21 1991 John Gilmore (gnu at cygint.cygnus.com)
2837 Cleanup for release 3.94.2:
2839 * Makefile.dist: Pull REMOTE_OBS. Fix saber includes for BFD
2840 include files. Roll version to 3.94.2.
2842 * coffread.c (init_stringtab): Read length into unsigned char
2843 array before swapping; don't assume 32-bit longs.
2845 * target.c (target_info): Don't bother with get_sym_file, just use
2846 the symfile global variable.
2847 * symtab.h, symfile.c (get_sym_file): Delete it.
2849 * dbxread.c (dbx_symfile_init): Don't depend on long == 4 bytes.
2850 (define_symbol): Set symbol line number to 0 if not gcc-compiled.
2851 (read_type): Replace one more error() with complain().
2853 * mipsread.c (parse_partial_symbols): Replace printf with complain.
2855 * i960-tdep.c: Fix copyright attribution.
2857 * config.gdb: Quote all backquotes in doublequotes. You can
2858 quote me on that. BSD 4.4 shell found this one.
2860 * infptrace.c (throughout): The third argument to ptrace is an
2863 * infrun.c (wait_for_inferior): When program has terminated, we
2864 have to call target_terminal_ours before we pop that target off
2865 the stack (e.g. before a call to target_kill or
2866 target_mourn_inferior). This fixes problem where a program
2867 terminates, then GDB stops for (tty output) and you have to type
2868 "fg" to the shell to resume it. FIXME: This code for what to
2869 do after termination really should be in normal_stop instead.
2871 * gdbcore.h (read_memory_check): Change declaration; it changed
2874 * terminal.h: Include <sgtty.h> before <sys/ioctl.h>, since in BSD
2875 4.4 prereleases, this avoids a bug in their sgtty compatability
2877 * remote.c: Use terminal.h rather than hand-rolling the same.
2879 * signame.c, signame.h (psignal): Arg is unsigned, not int.
2880 * utils.c (strsave, strstr): Fix arg types.
2881 * valprint.c (val_print): lint
2883 MIPS symbol table support from Per Bothner:
2885 * symfile.c (symtab_fns): Remove initializer table that needs to
2886 be hacked for each new symbol file format supported.
2887 (add_symtab_fns): New function, chains symbol table
2888 handlers into the global list.
2889 (symfile_init): Search this list.
2890 * symfile.h: Add next pointer, declare add_symtab_fns.
2891 * coffread.c (_initialize_coffread): Call add_symtab_fns.
2892 * dbxread.c (_initialize_dbxread): Call add_symtab_fns.
2894 * mipsread.c (psymtab_to_symtab_1): return void instead of (struct
2895 symbol *). Thus, we no longer need the hack to trash
2896 pst->filename. Good, since that hack confused code in symfile.c!
2898 (reorder_symtabs, destroy_all_symtabs): Removed static
2899 all_symtabs, which was used to qsort symtabs in reorder_symtabs.
2900 Instead, the latter now uses a temporary array (stack-allocated
2901 from an obstack, and then freed).
2903 (parse_symbol): Added a hack to fix up BLOCK_{START,END} if they
2904 haven't been set in the outermost stBlock of a procedure. This was
2905 a problem with f77 binaries on Ultrix 4.?.
2907 (new_symtab, new_symbol, new_type): Continue changing code to use
2908 obstacks more and otherwise conform to dbxread internal style.
2909 Made the free_code of symtabs be free_linetable (as in dbxread)
2910 instead of free_contents. This implies memory leaks when reading
2911 a new symbol table, until the conversion is finished. Did change
2912 (struct symbol) and (struct type) to be allocated on the
2913 symbol_obstack. Blocks and blockvectors are among the things
2916 * mipsread.c (parse_partial_symbols, parse_fdr): It hasn't been
2917 tested much, but it solved one problem (reported by Meissner), and
2918 cleans up some other things. The problem happened when an
2919 included file contains actual code (functions) and not just
2920 definitions. The mips coff is a little inconvenient there, since
2921 it may cause a procedure to be mapped to the wrong psymtab.
2923 * mips-tdep.c (heuristic_proc_desc): Minor cleanup.
2924 * mips-xdep.c (fetch_core_registers): Minor cleanup. FIXME,
2925 this will need work for the new core paradigm.
2927 Opcode patches from the net:
2929 * mips-opcode.h: fix incorrect disassembly of the mfc1, cfc1, and
2930 ctc1 instructions. Also, the cvt.d.w and cvt.s.w instructions were
2931 missing altogether - they are added here. From Bruce Bauman.
2932 * mips-opcode.h: The low mask for C0 instructions was too small.
2933 From Garrett Lau. I modified the fix to check the entire 32-bit
2936 * ns32k-opcode.h: Fix opcodes for deiw and deid. From Bruce
2939 Thu Mar 21 12:56:46 1991 John Gilmore (gnu at cygint.cygnus.com)
2941 Roll in changes from Per Bothner (Tue, 25 Sep 90 11:11:04):
2943 * dbxread.c (read_type): Pointer subtraction (value_sub in
2944 valarith.c) sometimes failed because the types of the
2945 pointers being subtracted were not identical.
2946 These differed because dbxread.c was allocating pointer types
2947 using dbx_alloc_type+smash_to_pointer_type instead of
2948 lookup_pointer_type. I failed to find a justification for the
2949 former, so I changed it to use the latter. Similarly, I
2950 replaced smash_to_function_type by lookup_function_type,
2951 and smash_to_reference_type by lookup_reference_type.
2953 * mipsread.c (parse_symbol, upgrade_type, parse_procedure,
2954 _initialize_mipsread): corresponding changes.
2956 * symtab.c (smash_to_{pointer,reference,function}_type): eliminate.
2958 * source.c (mod_path): Do tilde_expand on each component of the path,
2959 rather than on the (list of) paths as a whole.
2960 (print_source_lines): Set first_line_listed in addition to
2961 current_source_symtab and current_source_line. If the source was
2962 not findable, after a "dir" command to fix the problem,
2963 a "list" would get the wrong lines.
2965 While I was there... (gnu):
2967 * dbxread.c (read_type): Change error to complaint.
2969 Thu Mar 21 12:56:46 1991 John Gilmore (gnu at cygint.cygnus.com)
2971 First attempt at detailed understanding of symbol table memory alloc.
2973 * dbxread.c (dbx_symfile_read): Free our string table if we
2974 aren't the mainline. Free the "info" struct since we're done with
2976 (init_psymbol_list): Free any previously allocated psymbol lists.
2977 (): FIXME: Should realloc-down the psymbol lists when done reading
2978 the main symbol file?
2980 * symmisc.c (free_symtab): Free fullname field too.
2982 * xm-hp300hpux.h (USG): #undef then #define so Makefile can -D.
2983 (REGISTER_ADDR): Make result type unsigned int.
2985 * xconfig/{i386*,hp300hpux,altosgas,altos}: All config files that
2986 define REGEX must also define REGEX1 (its dependency).
2988 Tue Mar 19 21:28:57 1991 John Gilmore (gnu at cygint.cygnus.com)
2990 * tconfig/i960: No longer works, points you at vxworks960 or

2995 * Makefile.dist: Remove all trace of xgdb.
2997 * breakpoint.c (breakpoint_1): Pass demangle arg to
2998 print_address_symbolic.
2999 (clear_breakpoints): Remove unused function.

3003 * gdb-int.texinfo (Host versus Target): Add section on what is
3004 a "host" feature versus what is a "target" feature.
3006 * infcmd.c (path_command, path_info): Handle the PATH variable
3007 (object search path) as conveniently as the source search path.
3008 * environ.c (set_in_environ): Set some vars in GDB's environment,
3009 in addition to the child's. PATH, G960BASE, G960BIN for starters.
3010 * source.c (mod_path): New function, from guts of
3011 directory_command, modifies a path. Used by path_command.
3012 (directory_command): Call it.

3016 (printchar): Use it.
3017 (strsave): Provide this handy helper routine.
3018 (set_width_command): Rename set_screen_width_command.
3019 (_initialize_utils): "set screen-width" => "set width";
3020 "set screen-height" => "set height"; add sevenbit-strings.
3022 * infcmd.c (do_registers_info): Print floating point registers
3023 in raw hex as well as float format, regardless of whether it is
3024 a "virtual" convertible register.
3025 * tm-sparc.h (PRINT_REGISTER_HOOK): Print every pair of float
3026 regs as a double, just in case it's being used that way.
3027 * values.c (unpack_long): Comment on array/function coercion.
3028 (unpack_double): Argument is in target byte order now. For
3029 integer arguments, just call unpack_long and float the result.
3030 * m68k-tdep.c: include defs.h for "const" handling.
3031 * remote-nindy.c: Use ieee-float stuff.
3032 (nindy_fetch_registers): Unpack double regs to host double, then
3034 (nindy_store_registers): Pack extendeds to host double, flip
3035 around by misusing unpack_double, send as target double.
3037 * tm-vxworks68.h (FRAME_CHAIN): Handle current frame pointer of
3038 zero, as when stopped at the first instruction of a process.
3040 * blockframe.c: Fix filename in comment (param.h => tm.h).
3041 * sparc-tdep.c (skip_prologue): More explicit nudging comments.
3042 * tm-68k.h: Fix typos.
3044 Fri Mar 15 01:09:34 1991 John Gilmore (gnu at cygint.cygnus.com)
3046 Changes from a bringup on the DEC Vax under Ultrix 4.0.
3048 * coredep.c (fetch_core_registers): Pass end-address of register
3049 section to register_addr as expected. Don't call supply_register
3050 if we'd just pass it garbage.
3052 * dbxread.c (read_dbx_symtab): Skip N_NSYMS on Ultrix.
3054 * exec.c (xfer_memory): Use boolean xfer_fn result, not int.
3056 * target.c (push_target, target_info): Cast enums to int for < or

3060 even if we can't print it.
3062 * xm-vax.h (MISSING_VPRINTF): No longer missing in Ultrix V4.0.
3064 Sat Mar 9 10:08:20 1991 John Gilmore (gnu at cygint.cygnus.com)

3078 * m68k-tdep.c: Define ext_format_68881.
3079 * sparc-tdep.c: Define ext_format_sparc, though unused.
3080 * Makefile.dist (HFILES): Add ieee-float.h.
3081 * inftarg.c: #include "ieee-float.h" for the REGISTER_CONVERT

3087 * nindy-share/nindy.c (coffstrip): Routine to run bfd_strip.
3088 * Makefile.dist: Remove references to nindy-share/coffstrip.c.
3089 * tconfig/nindy960: Remove reference to coffstrip.o.
3091 * Makefile.dist: Roll version number to 3.94.1 (not yet final).

3096 * dbxread.c: Remove static symfile_bfd.
3097 * infcmd.c (do_registers_info): Add PRINT_REGISTER_HOOK, though
3099 * inftarg.c (child_detach): Pop the child_ops vector if the
3100 detach is successful.
3101 * remote-nindy.c (nindy_create_inferior): Don't push a new
3102 nindy_ops since nindy uses the same one for execution and memory
3104 * core.c (core_ops): Use child_attach and child_create_inferior
3105 rather than default attach and create_inferior functions.
3107 Handle floating point registers in core files.
3109 * sparc-xdep.c (fetch_core_registers): Rewrite for float support.
3110 * sun3-xdep.c (fetch_core_registers): Rewrite for float support.
3111 This version untested since BFD doesn't yet support sun3 core
3113 * hp300hpux-xdep.c: Rewrite fetch_core_registers to new calling
3114 conventions. Fix comments and style. This version has not
3115 been compiled yet, since we have no HP inhouse.
3116 * core.c (get_core_registers): Look for two sections, ".reg"
3117 and ".reg2", and pass both to fetch_core_registers sequentially.
3119 Revise directory path yet again.
3121 * source.c (forget_cached_source_info): Not static any more.
3122 (init_source_path): New default source path is "$cdir:$cwd".
3123 (dir_command): Handle variable arguments ($cdir, $cwd).
3124 (source_info): Print "Compilation directory" rather than
3125 "Originally compiled in" to remind people of $cdir.
3126 (openp): If the path contains $cwd, use current directory.
3127 (open_source_file): If compilation directory is known, replace
3128 first $cdir in path with the compilation directory.
3129 (print_source_lines): Even if we can't print the lines, set the
3130 current symtab and line for future commands like "info source" or
3131 "breakpoint". Also, error message now contains the file name,
3132 line number, and file access error message.
3133 (_initialize_source): Fix help text to describe changes.
3134 * main.c (cd_command): Forget cached source info when we chdir.
3135 * utils.c (strstr): Add simple implementation.

3139 * coffread.c (read_one_sym, init_linetable, init_stringtab):
3140 Byte-swap COFF symbol tables if necessary when reading them in.
3141 Use complain() to replace error message in one spot. Needs
3142 corresponding change in bfd/coff-code.h to make some symbol
3143 swapping routines non-static.
3145 Mon Mar 4 00:53:40 1991 John Gilmore (gnu at cygint.cygnus.com)

3160 <rpc/rpc.h> and <rpc/types.h>.
3162 Sat Mar 2 15:47:55 1991 John Gilmore (gnu at cygint.cygnus.com)
3164 * i960-tdep.c (examine_prologue): Add new argument limit,
3165 which stops the scan at the end of the prologue, or at the PC.
3166 This fixes a problem where it walks down into the code for the
3167 user's statements if that code looks like function prologues.
3168 Mark Fox and I have been bouncing this code back and forth, making
3169 small changes to it. Callers changed to match.
3171 Tue Feb 26 01:47:07 1991 Cygnus John Gilmore (cygnus at yuba)
3173 Cleanup for gdb-3.94 release final:
3175 * Makefile.dist: Remove remote-vx.c, remote-nindy.c, and all
3176 the .c files from vx-share and nindy-share, from the various
3177 macros, since they are not found via ALLDEPFILES.
3178 (SFILES): Add tm-i960.h.
3179 (alldeps.mak rule): Break out ALLDEPFILES_MAINDIR and
3180 ALLDEPFILES_SUBDIR. List all the nindy and vxworks subdir files
3182 (TAGFILES_MAINDIR): Change ALLDEPFILES to ALLDEPFILES_MAINDIR.
3183 (gdb.tar.Z): Use ALLDEPFILES_SUBDIR as well as SFILES_SUBDIR.

3187 * am29k-tdep.c: Add contribution line.
3188 (examine_prologue): Cache information about function prologues in
3189 the misc-function-vector to avoid lots of references over the
3190 serial line while examining instructions.
3192 * core.c (core_close): New function made from cleanup_core.
3194 * core.c, exec.c, inftarg.c, remote-eb.c, remote-nindy.c,
3195 remote-vx.c, remote.c, target.c, target.h,
3196 Update target_ops vector to add attach, close, and load entries.
3197 Use add_syms_addr_command, not add_file_addr_command, for
3198 add_file. Break out close routine from existing code.
3200 * dbxread.c (really_free_pendings): Don't free pending_blocks;
3201 they are in an obstack.
3202 (read_dbx_symtab): Relocate end_of_text_addr in the psymtab.
3204 (define_symbol): Add symbol type parameter; change callers;
3205 pass type parameter to DBX_PARM_SYMBOL_CLASS macro to allow
3206 it to influence the symbol class on the i960.
3207 (define_symbol): Swap LOC_CONST's into target byte order.
3209 * exec.c (exec_close): New function.
3210 (exec_file_command): Call it.
3212 * findvar.c (read_relative_register_raw_bytes): Doc byte order,
3213 Fix byte order of frame pointer.
3214 (read_var_value): Result of 0 if var's value can't be found,
3215 e.g. missing FRAME_ARGS_ADDRESS. Byte-swap LOC_CONST and
3216 LOC_LABEL values to target order. Add LOC_LOCAL_ARG.
3217 (locate_var_value): Use read_var_value and use its lazy address
3218 as the location of the var's value. Lint.
3220 * i960-pinsn.c (next_insn): Add routine from vxgdb for scanning
3223 * i960-tdep.c (arg_address, i960_frame_find_saved_regs): Remove
3224 obsolete Intel versions in favor of vxgdb versions.
3225 (check_host, byteswap, byteswap_val, reorder_val): Eliminate
3226 code dealing with byte order of values, which Intel did in host byte
3227 order rather than gdb-4's target byte order.
3228 (i960_frame_chain_valid): Move to nindy-tdep.c.
3229 (examine_prologue, skip_prologue, frame_find_saved_regs,
3230 frame_args_address, leafproc_return, saved_pc_after_call,
3231 pop_frame): Add vxgdb versions from Mark Fox.

3233 to deal with the saved value of G13 (struct return address
3235 (frame_args_address): Modify Mark's version to prefer the
3236 saved value over the current value in the topmost frame.
3237 Cache result in the frame info to avoid performance hair in
3239 (print_fault): Add gdb960 code for printing faults.
3240 (_initialize_i960): Actually call check_host.
3242 * ieee-float.c (ieee_extended_to_double, ieee_double_to_extended):
3243 add stub routines. FIXME, these currently just return zero!

3246 (attach_command): Call target_attach, not target_open, now.
3248 * infrun.c (normal_stop): Make global, not static, for vx_attach.
3249 (child_attach): Rename from child_open.
3250 (wait_for_inferior): Use PRINT_RANDOM_SIGNAL. If stop_pc is zero,
3251 don't confuse it with a zero step_resume_break_address.
3253 * inftarg.c (child_detach): Eliminate inferior_pid test.
3254 (child_files_info): Clean up message a bit.
3255 (child_ops): Use child_attach, not child_open, to attach.
3257 * mem-break.c: #ifdef out the whole file if BREAKPOINT is not
3258 set (e.g. on VxWorks or NINDY). Move read_memory_nobpt from
3259 findvar.c to here, since it depends on the contents of the
3260 shadow_contents of breakpoints, but keep if #if 0 since it is
3263 * nindy-tdep.c: New file, contains nindy_frame_chain_valid, moved
3266 * printcmd.c (address_info): Handle LOC_LOCAL_ARG. Lint.
3267 (ptype_command, display_command): Eliminate have_inferior_p and
3268 have_core_file_p in favor of target_has_stack or
3269 target_has_execution.
3270 (print_frame_args): Handle LOC_LOCAL_ARG. Eliminate duplicate
3271 code for actually finding the values of arguments, though we still
3272 keep track of the maximum stack offset for use in printing unnamed
3273 arguments. Handle missing FRAME_ARGS_ADDRESS.
3275 * remote-nindy.c (i960_print_fault): Move to i960-tdep.c.
3276 (struct nindy_regs): Define registers passed to/from nindy.
3277 (nindy_fetch_registers, nindy_store-registers): Translate between
3278 nindy and GDB formats for the registers.
3279 (dcache_init): Statically allocate the cache, since it was being
3280 allocated by a malloc that was never freed anyway.
3281 (nindy_create_inferior): Error, not core dump, if no exec file.
3282 (nindy_before_main_loop): Use target_load, not target_add_file.
3284 * remote-vx.c (net_load): Specify large timeout for load
3285 requests. Allow user to break out with INTERRUPT.
3286 (net_break): Remove useless code, clean up. Change callers.
3287 (parse-args, skip_white_space, find_white_space): Clean up arg
3288 parsing to cope with quoted strings.
3289 (net_wait, net_quit): Never call error, just return status.
3290 (vx_read_register, vx_write_register): Cleanup status checking.
3291 #ifdef the code based on which CPU we are using (960 or 68k),
3292 FIXME, this should be completely general but it isn't yet.
3293 (vx_xfer_memory, vx_resume): Cleanup status checking.
3294 (vx_run_files_info): Improve message.
3295 (vx_load_command): Renamed from vx_add_file_command. Allow load
3297 (net_ptrace): Remove unused routine.
3298 (vx_wait): Adopt code from vxgdb960 to cope with broken
3299 connections to target machine and prompt to disconnect. Remove
3300 debug printouts. Map some EVENT_'s to SIGnals.
3301 (add_symbol_stub, vx_open): Print names of object files we found,
3302 and "ok" if we read their symbols OK. Clarify output in general.
3303 (vx_attach, vx_detach, vx_kill): Add these commands.
3304 (vx_convert_from_virtual, vx_convert_to_virtual): Simplify.
3305 (vx_run_ops): Turn off all_mem, to avoid spurious msg in the
3306 "info files" output, and create_inferior, since we already have
3309 * stack.c (frame_info): Replace Frame_unknown with 0.
3310 (print_frame_arg_vars): Handle LOC_LOCAL_ARG.
3311 (return_command): Pop until the PC matches as well as the FP,
3312 so it works even if the FP is shared with another function,
3313 as in "frameless" or "leaf" procedures.
3315 * symfile.c (load_command): renamed from add_file_target_command.
3316 (add_syms_addr_command): renamed from add_file_addr_command.
3317 (add_syms_command): Stub to call target_add_syms.
3318 (_initialize_symfile): Change command names and descriptions,
3319 add-file => add-syms, and load from alias to its own command.
3321 * target.c (kill_or_be_killed, maybe_kill_then_attach,
3322 maybe_kill_then_create_inferior): Default for attempts to start
3323 a process, if one is already running, is to ask about killing
3324 it and retry if yes.
3325 (upstack_create_inferior): #if-0 it, strata obsolete it.
3326 (push_target, unpush_target, pop_target): to_close() a target
3327 before unstacking it.
3328 (target_info): Renamed from target_files_info.
3329 (_initialize_targets): Rename "i files" as "i target", accessible
3332 * target.h: Improve comments about the target_ vectored routines.
3334 * tm-i960.h: Remove NINDY-specific stuff to tm-nindy960.h.

3337 (SKIP_PROLOGUE): No longer a no-op.
3338 (SAVED_PC_AFTER_CALL): Now handles leaf procedures.
3339 (*_REGNUM): Sort register numbers.
3340 (REGISTER_BYTES, REGISTER_BYTE, REGISTER_RAW_SIZE,
3341 MAX_REGISTER_RAW_SIZE, REGISTER_CONVERTIBLE,
3342 REGISTER_CONVERT_TO_VIRTUAL, REGISTER_CONVERT_TO_RAW): Float regs
3343 are now 10 byte extendeds, not 8 byte doubles.
3344 (FRAME_CHAIN_VALID): Make this config-dependent, since it differs
3345 for nindy versus vxworks targets. FIXME, this should possibly go
3346 in the target vector.
3347 (EXTRA_FRAME_INFO, INIT_EXTRA_FRAME_INFO): Cache both
3348 frame_saved_regs and arg pointer with each frame.
3349 (FRAMELESS_FUNCTION_INVOCATION): New leafproc support.
3350 (FRAME_ARGS_ADDRESS): Use cached result.
3351 (FRAME_ARGS_ADDRESS_CORRECT): New, avoids g14 guessing.
3352 (FRAME_FIND_SAVED_REGS): Change arg to subsidiary fn.
3353 (PRINT_RAMDON_SIGNAL): Call print_fault.
3354 (POP_FRAME): Now works.
3356 * tm-nindy960.h: Break this off tm-i960.h. NINDY-specific
3357 option parsing and startup; STACK_END_ADDR, FRAME_CHAIN_VALID,
3358 BREAKPOINT, and DECR_PC_AFTER_BREAK are here.
3359 (ADDITIONAL_OPTION_HANDLER): use target_load, not
3362 * tm-vxworks960.h: Break this off tm-i960.h. VxGDB specific
3363 startup; DECR_PC_AFTER_BREAK, and FRAME_CHAIN_VALID are here.
3365 * valarith.c (value_subscripted_rvalue): Avoid handling
3366 floats and doubles specially; it gave alignment errors. Lint.
3368 * valops.c (value_of_variable, value_of_this): Error if unknown
3371 * valprint.c (print_floating): Bcopy rather than pointer-deref,
3372 to avoid alignment problems.
3373 (value_print): Handle unknown value address.
3374 (cplus_val_print): Two args are ignored; remove them. Change caller.
3375 (val_print): Use unpack_long rather than pointer-deref.
3378 (unpack_long, unpack_double): Use bcopy rather than pointer-deref
3379 to avoid alignment problems.
3380 (value_being_returned): Error if return value unknown.
3381 (set_return_value): Add bogosity warning, FIXME. *
3383 * TODO: A woman's work is never done.
3385 * Makefile.dist: Distribute REMOTE_OBS into tconfig files.
3386 Separate INCLUDE_CFLAGS for use with lint. Add LINTFILES.
3387 Add ieee-float.o to OBS.
3388 * tconfig/{nindy960,vxworks68,vxworks960}: Include the desired
3389 REMOTE_OBS remote-interface files in the TDEPFILES and TM_FILE.
3390 * tconfig/i960: FIXME. Half-merge, produce warning if config'd.
3392 Changes to generalize the VxWorks RPC protocol slightly, to handle
3393 i960 as well as 68000.
3395 * vx-share/dbgRpcLib.h (VX_SOURCE_STEP): Add.
3396 * vx-share/reg.h: Produce i960 regs #ifdef I80960
3397 * vx-share/xdr_ptrace.c: Skip FPA registers if 960.
3398 * vx-share/xdr_rdb.h: Add SOURCE_STEP struct and xdr decl.
3399 * vx-share/xdr_rdb.c: Add xdr_SOURCE_STEP routine.
3400 * vx-share/xdr_regs.c: Add xdr_regs, xdr_fp_status, xdr_ext_fp
3401 for i960. Change xdr_vectors to xdr_opaques for 68k registers,
3402 so they will move in target byte order rather than network
3403 byte order (happens to be the same).
3405 Mon Feb 25 03:41:44 1991 John Gilmore (gnu at cygint.cygnus.com)
3407 * tm-convex.h (END_OF_TEXT_DEFAULT): Remove #if 0'd block.
3409 Sun Feb 24 00:55:53 1991 John Gilmore (gnu at cygint.cygnus.com)
3412 Add contribution lines to various files, showing where they
3415 * breakpoint.c (break_insn, check_break_insn_size,
3416 read_memory_nobpt): Remove to mem-break.c.
3418 * xm-*.h, param-no-tm.h, tm-29k.h, valprint.c: Change BYTE_ORDER to
3421 * tm-29k.h (STAB_REG_TO_REGNUM): Warn user if symbol table
3422 entry has bad register number. This change is not
3423 tested in this release, FIXME.
3425 * frame.h: Eliminate Frame_unknown in favor of a simple zero.
3428 * value.h: Force value's contents field to be aligned to hold
3429 at least a double or a long long (if supported). This avoids
3430 doing bcopy's in and out of the contents field.
3432 (step_1): Avoid coredump under obscure circumstances when we
3435 * symtab.h (misc_info): Add field to misc function vector for
3436 any kind of cached information the target code desires. AMD
3437 29000 uses this to avoid repeating examine_function_prologue's.
3439 * coffread.c: Lint. Remove static symfile, read_section_header.
3440 core.c (have_core_file_p): Lint: remove.
3441 expprint.c (print_subexp): Lint.
3442 infptrace.c, valops.c, valprint.c: lint.
3444 Roll in changes from vxgdb-5.0.1:
3446 * symtab.h: Comment byte order of each address class. Add
3447 LOC_LOCAL_ARG for frame-relative args (960).
3448 expread.y: Use LOC_LOCAL_ARG where LOC_ARG is used.
3449 symtab.c, symmisc.c: ditto.
3451 * infrun.c (init_wait_for_inferior): Clear stop_signal.
3453 * remote.c (remote_resume): Error if resume with a signal.
3455 * symfile.c (prim_record_misc_function): Clear misc_info.
3456 (fill_in_vptr_fieldno): Check stub type of arg.
3458 * valops.c (value_cast): Avoid looking up names of types whose
3459 name we don't know, to prevent coredump. Sun CC produces typedef
3460 rtx and the name of *rtx is zero...
3462 Mon Feb 18 21:16:25 1991 John Gilmore (gnu at cygint.cygnus.com)
3464 Roll in changes from final AMD 29000 port (Tiemann).
3466 tconfig/am29k: Add COFF_ENCAPSULATE and TARGET=TARGET_AM29K
3467 for ../include/a.out.encap.h. This might not work now that BFD
3468 is separately compiled. Instead, BFD support for encap will have
3469 to translate machine type 29k into the right COFF_MAGIC.
3471 * infcmd.c: Remove references to inferior_pid that aren't used
3472 in actual ptrace calls; use target_has_execution, etc.
3473 (have_inferior_p): Remove function.
3474 (program_info): Print target info rather than "process number";
3475 avoid gratuitous messages unless from_tty.
3476 (run_stack_dummy, finish_command): Set proceed_to_finish.
3477 infrun.c: Remove inferior_pid refs. Decl & init proceed_to_finish.
3478 main.c: Lint. Lose have_inferior_p().
3479 inferior.h (have_inferior_p): Remove, lint.
3480 (proceed_to_finish): Add flag to ask that all regs be saved
3481 by normal_stop, for the few commands that need it, speeding up
3482 serial I/O. Add comments to stop_registers.
3484 * remote-eb.c: Remove newline from breakpoint message we grep
3485 for. Never time out when running the user program.
3489 Wed Feb 13 15:34:40 1991 John Gilmore (gnu at cygint.cygnus.com)
3491 Roll in changes from vxgdb-5.0.1:
3493 * dbxread.c (read_dbx_symtab): If we encounter a "FORTRAN COMMON"
3494 symbol in its raw form, we are processing an unlinked ".o" file.
3495 See if the target environment has assigned it an address, using
3496 target_lookup_symbol (VxWorks does), and enter it into the symtab
3499 * tm-vxworks.h (FRAME_CHAIN, FRAME_CHAIN_VALID): Override usual
3500 68k versions for a simpler version that assumes zero FP at bottom.
3501 Fixes bug of truncated stack reports.
3503 * target.h (target_lookup_symbol): Define this routine's args
3504 and result, finally.
3506 * target.c (nosymbol): Default routine for target_lookup_symbol.
3507 (target_default): Default lookup_symbol and call_function too.
3508 (files_info): Only print has_all_memory warning if a non-dummy
3511 * remote-vx.c (vx_read_register, vx_convert_to_virtual,
3512 vx_convert_from_virtual): If target does not have floating point,
3513 zero register "values", and avoid doing cross-net conversions.
3514 (vx_lookup_symbol): Rename net_lookup_symbol, add to vectors.
3515 (vx_open): Rearrange code that attaches to target and reads
3516 symbols for all loaded modules, to work if some of the modules
3517 are not accessible. Add symbol_stub() and add_symbol_stub()
3518 as callbacks from catch_errors(). Allow connect attempt to be
3519 interrupted painlessly with ^C (FIXME, there are still some bugs
3520 if the interrupt happens during symbol reading.). Print
3521 final message with puts_filtered, since symbol messages are
3526 * main.c (catch_errors): Only print errstring if non-null.
3527 (command_loop): Avoid an ioctl per command to test ISATTY.
3529 * remote-vx.c (net_load): make static; avoid sophomoric msg.
3530 (vx_xfer_memory): Return correct result!
3531 (vx_files_info): Indicate whether target has float or not.
3532 (vx_lookup_symbol): Complain, not error, if target gone.
3533 (vx_open): Print "Connected" msg before disabling immediate-quit.
3534 [FIXME: lookup_symbol and vx_open changes need testing.]
3536 target.c, remote-eb.c, inftarg.c, am29k-opcode.h, target.h,
3537 tm-29k.h, tmm-vxworks68.h, symfile.c, gdb-int.texinfo: Add
3538 contributor lines and update copyrights to 1991.
3540 Changes from an attempted H-PUX host port:
3542 * infptrace.c (PT_ATTACH, PT_DETACH): Handle HP/UX, which
3543 defines PT_ATTACH and PT_DETACH but not PT_KILL.
3544 * remote-eb.c (eb_open): Misplaced endif kills sysv H/PUX.
3545 * remote-vx.c: include <sys/time.h> for HPUX.
3546 * hp300hpux-xdep.c (fetch_core_registers): Rewrite old
3547 "core_file_command" routine to BFD regime. May not work yet.
3549 Attempted port of "gdb-3.4 Van Jacobson xgdb" to modern gdb.
3551 * xgdb.c: Replace X10 version with some VJ version.
3552 (FIXME: Its copyright assignment is not on record.)
3553 * xgdb.c: Update include files to X11R4 (Xaw crud).
3554 (xgdb_display_source, create_text_widget): fix call to
3555 get_filename_and_charpos. Rewack source window stuff for X11R4
3556 (gleaned from include files, and "nm's" of binary libraries, since
3557 I had no doc available).
3558 (append_selection, append_selection_word): Disable with FIXME
3559 since R4 changed interface here.
3560 (create_buttons): Add back the old set of buttons.
3561 (xgdb_create_window): Fix call to XtInitialize (&argc not argc).
3563 * Makefile.dist (xgdb, xgdb-init.c): Update for X11R4 on Suns.
3564 Roll VERSION to 3.94 (not yet final though).
3566 Sat Feb 9 09:46:25 1991 John Gilmore (gnu at cygint.cygnus.com)
3568 * obstack.h (obstack_ptr_grow, obstack_ptr_grow_fast,
3569 obstack_int_grow, obstack_int_grow_fast): Eliminate
3570 cast on left of assignment, which gives MIPS cc fits and is
3573 * sparc-pinsn.c (print_insn): Eliminate 'set' test, subsumed by
3574 F_ALIAS. Use printf, not fprintf, when not passing a file
3576 (compare_opcodes): Check that identical instructions have
3577 identical opcodes, complain otherwise.
3579 * sparc-opcode.h (st %fsr): Fix opcode "lose" mask. This
3580 was reported by Roland McGrath.
3581 (unimp): Only match if exactly zero instruction. (Roland)
3582 (branches and traps): Generate all variations of these
3583 instructions with macros, based on a single call that defines
3584 each condition name and its binary representation.
3585 (set): Turn on alias bit, to avoid test in sparc-pinsn.c.
3587 * valprint.c (val_print_fields): Take, and use, format parameter.
3588 This means that "p/x struct" again prints the elements in the
3589 desired format. Changed callers.
3591 * stack.c (frame_info): Use filtered output, and indicate wrap
3592 points. Remove kludgy formatting designed to avoid line wrap.
3594 * utils.c (wrap_here): If the line is already full (because
3595 we had printed a long indent or long wrapped string), do an
3596 immediate newline-and-indent.
3598 * m68k-pinsn.c (print_insn_arg): Bugfix from
3599 ntmtv!thompson@ames.arc.nasa.gov (Mike Thompson): 'bkpt #0'
3600 instruction is incorrectly disassembled as bkpt #8.
3602 * dbxread.c (end_psymtab): Bugfix from Peter Schauer
3603 <pesrem@regent.e-technik.tu-muenchen.de>: If you want to set a
3604 breakpoint in a *.y file gdb will say Reading in symbols for *.y...
3605 and then will dump core (sometimes). I traced it back to an
3606 uninitialized symfile_name in psymtab_to_symtab.
3607 (const_vol_complaint): Add quotes to message.
3608 (define_symbol): Only believe line number if gcc_compiled.
3609 Avoid allocating symbol if we will not return it.
3611 Add target strata support so that newly established targets go
3612 into their right place in the target stack (e.g. a new exec file
3613 doesn't wipe out the ability to access the running process).
3615 * target.h, core.c, exec.c, inftarg.c, remote-eb.c,
3616 remote-nindy.c, remote-vx.c, remote.c, target.c: Add to_stratum
3617 and initialize it properly in all the targets.
3619 * target.h: Document strata. Change return type of push_target.
3621 * target.c (nomemory): new function for dummy memory access.
3622 (tcomplain): Rename complain, now also used in symfile.c.
3623 (push_target): Push targets within strata. New return value shows
3624 whether new target is on top of stack or not. Always keep dummy
3626 (target_files_info): Ignore dummy target.
3628 * core.c (core_open): Warn user, and skip accessing file, if the
3629 core target is not the topmost target in the stack.
3630 * remote-nindy.c (nindy_create_inferior): Avoid unpush_target, now
3633 * remote-vx.c: Remove vx_prepare_to_store from vxworks memory
3634 target_ops, it doesn't belong there since we have no regs there.
3635 Change name of target from machine => memory to clarify.
3637 Thu Feb 7 16:32:09 1991 John Gilmore (gnu at spiff.cygnus.com)
3639 * Freeze version 3.93 for release.
3641 * Makefile.dist: Handle vx-share and nindy-share subdirs
3642 properly when building gdb.tar.Z.
3644 * symtab.c: lint; add no_symtab_msg to consolidate the messages
3645 printed in various places, so I could change just one copy.
3647 * dbxread.c, coffread.c: Change references to bfd->iostream
3648 to cast to FILE *, now that BFD avoids needing types defined
3649 in other header files.
3651 Tue Feb 5 21:39:35 1991 John Gilmore (gnu at cygint.cygnus.com)
3653 * command.c, dbxread.c, expprint.c, infcmd.c, infptrace.c,
3654 infrun.c, printcmd.c, remote-nindy.c, source.c, sparc-tdep.c,
3655 sparc-xdep.c, symfile.h, symmisc.c, utils.c, valprint.c: Lint
3656 (actually gcc -Wall).
3658 * dbxread.c: Remove first_global_sym, last_global_sym, since
3659 they are never referenced.
3661 * defs.h (baud_rate): Declare.
3662 main.c: Define it, and add the -b option to set it.
3664 * gdb-int.texinfo: Add text on how to define a new host or target
3665 architecture, prompted by Per Bothner's questions about MIPS
3668 * gdb.texinfo: Document "complaints". Change doc of -q since
3669 gdb no longer prints the copyright and blurb if you specify a file
3670 name to be debugged (just like Emacs). Add doc for Nindy-specific
3671 command line flags for specifying target serial port and such.
3672 Update copyright to 1991.
3674 * gdbcore.h: Remove a large mass of now-useless crud, since BFD
3675 has taken over for us the job of ripping up executable files. The
3676 crud caused Per Bothner's port to not compile.
3678 * infrun.c (normal_stop): Avoid printing "Program exited
3679 normally" if we are in batch mode. This allows a GDB which
3680 executes a program on a target system, to behave like a Unix
3681 command (input from stdin, output to stdout, no extraneous
3684 * main.c (main): Allow additional machine-dependent command line
3685 options to be specified with the ADDITIONAL_OPTIONS,
3686 ADDITIONAL_OPTION_CASES, ADDITIONAL_OPTION_HELP, and
3687 ADDITIONAL_OPTION_HANDLER macros. Also allow machine-dependent
3688 processing to occur just before the main loop with
3689 BEFORE_MAIN_LOOP_HOOK.
3690 (main): If a "core file" argument is specified, and it is not a
3691 core file, try it as a process ID to attach.
3692 (symbol_completion_function): Attempt to cope with
3693 "show screen-" TAB, not very successfully. This needs more work,
3695 (batch_file): New function, returns whether we are reading
3696 commands from an interactive tty on stdin, or from somewhere else.
3697 Called by normal_stop since it doesn't get from_tty passed down
3698 to it like many commands do.
3700 * remote-nindy.c: Handle command line options for nindy
3702 (nindy_before_main_loop): Prompt user for tty name if they
3703 don't specify it before getting to the interactive command loop.
3705 * tm-i960.c: Add ADDITIONAL_OPTIONS, etc, to handle -O, -brk,
3706 and -r command line options. Also add hook before main loop
3707 to make it easy to specify a tty.
3709 * TODO: More things to do, one done.
3711 Mon Feb 4 23:57:39 1991 John Gilmore and Mike Tiemann (at cygint.cygnus.com)
3713 * dbxread.c: Make complaint() calls pass pointer, not struct.
3714 Add complaints about badly formatted C++ type information
3715 (const/volatile indicator, and parse errors resulting in
3716 error_type). Fix C++ virtual member fn comment.
3717 (read_struct_type): Avoid bumping pointer if we got a parse
3718 error; this prevents our walking beyond the end of a string.
3719 Terminate loop on null char as well as semicolon.
3720 (process_one_symbol): Fix the LBRAC fix so that it uses the
3721 last previous SLINE, FUN, or SO record's PC address. C++ debug
3722 symbols did not have SLINE records in a useful order compared
3723 to the LBRAC records.
3724 (define_symbol): Handle "catch" records.
3726 * symtab.c (check_stub_type): Added new complain
3727 `stub_noname_complain' and added a consistency check to
3728 keep the debugger from crashing when finishing from an
3729 exception frame. A real fix will be needed later.
3731 Sat Feb 2 10:43:05 1991 John Gilmore (gnu at cygint.cygnus.com)
3733 * infcmd.c (attach_command): Make global.
3735 * Makefile.dist (REMOTE_OBS): Make these compile by default,
3736 but make them easy to comment out. Perhaps later they should
3737 be enabled by what CPU you configure for? FIXME.
3738 (VERSION): Roll to 3.93.
3739 (pinsn.o): Remove rule for obsolete file.
3740 (dbxread.o,coffread.o,mipsread.o): Use ${srcdir} explicitly.
3742 Run down a problem that manifested by printing the wrong function
3743 name in stack traces of read_ofile_symtab. Turned out that the
3744 problem was the SunOS 4.1.1 (and previous) C compiler outputs
3745 the LBRAC symbol with an address in the *data* segment, which
3746 blew our binary search through the blocks.
3748 * dbxread.c: Use the complain() facility consistently to bitch
3749 about problems in the symbol file we are reading.
3750 (finish_block): Add code to check the nesting of the blocks;
3751 complain and Procrust them to fit if wrong.
3752 (make_blockvector): Check the order of the blocks, complain
3753 [but don't cope] if wrong.
3754 (process_one_symbol): ifndef SUN_FIXED_LBRAC_BUG, check LBRAC
3755 symbols to be sure their PC value is greater than the last SLINE
3756 (line number) symbol we've seen, complaining and adopting the
3757 SLINE PC value if wrong.
3759 * symfile.h (struct complaint, complaint_root, complain,
3760 clear_complaints): Add.
3761 * symfile.c (complain, complaint_root, clear_complaints): Add
3762 facility to deal with non-fatal complaints and to regularize their
3764 (symbol_file_add): Clear complaint counters to allow new complaints.
3765 (initialize_symfile): Add 'set complaints' and 'show complaints'.
3767 * dbxread.c (dbx_symfile_read): Remember the address and size
3768 of the string table for the main symbol file, so we won't read it
3770 (dbx_psymtab_to_symtab): Fix the check for main symbol file,
3771 to avoid reading the string table yet again. Lint.
3772 (throughout): Improve filtered output, including word wrap.
3773 (read_range_type): Improve Bothner's fix to handle other types too.
3775 * utils.c: Improve line wrap implementation. Handle unlimited
3776 width by making chars_per_line unsigned.
3777 (puts_filtered): New, easy, function.
3779 * defs.h (puts_filtered): add.
3781 * mipsread.c (compare_symbols, sort_symtab): Remove these fns,
3782 call the identical sort_symtab_syms() in symfile.c instead.
3784 * expread.y: Suggest the `file' command rather than `symbol-file'.
3786 * command.h (enum var_types): Add zinteger for seroable
3788 * command.c (do_setshow_command): Handle var_zinteger. Restructure
3789 nested if's into a switch.
3791 * breakpoint.c (bpstat_print): If bpstat "print" flag is not set,
3792 we did not stop because of a breakpoint (it must have been for
3793 some other reason, like a "stepi"), so don't print anything.
3795 * symtab.c: Include <sys/types.h> all the time. Now that BFD
3796 doesn't include <sys/types.h>, old SunOS's require it for
3799 Sat Feb 2 10:39:15 1991 Per Bothner (bothner@cs.wisc.edu)
3801 A test port of gdb-3.92.6 to the Sony NEWS.
3804 Don't normally link in remote- or vx stuff.
3805 Some of it doesn't compile, and it wastes space for 99% of the users.
3806 Remove reference to no-longer-used HAVE_VPRINTF.
3807 Fixed BFD_DEP typo to BFD_DIR.
3809 Fix cast in arg to bfd_h_getlong.
3810 Make char *prefix be const.
3811 Fix how certain range types are mapped into builtin unsigned int types.
3813 Remove 2 #includes. They cause errors (on Sony, at least),
3814 and aren't needed (they wern't in earlier versions).
3816 print_address_symbolic should never demangle labels
3817 (since it prints *assembler-level* labels).
3819 [This was superseded by the change to printcmd below.]
3822 Add some "volatile" return types to avoid warnings.
3823 If MISSING_VPRINTF add vprintf function and not just macro
3824 (since vprintf is used in printcmd.c).
3826 Unless __GNUC__, use obstack_grow instead of obstack_ptr_grow.
3827 (The latter isn't grokked by some PCC-based compilers.)
3829 [This change is in abeyance, we prefer to fix obstack_ptr_grow.]
3831 Make chunk size of dont_print_obstack 32*4 instead of default 4096.
3832 * nindy-share/coffstrip.c
3833 Added some forward declarations (otherwise, gcc complains
3834 about implicit extern redefined as static).
3836 Sun Jan 20 02:38:19 1991 John Gilmore (gnu at cygint.cygnus.com)
3838 Changes inspired by Per Bothner:
3839 * printcmd.c (print_address_symbolic): Take additional parameter
3840 specifying whether to demangle.
3841 (print_address): Pass in asm_demangle to control demangling.
3842 (print_address_demangle): New fn, takes explicit arg to control
3844 * utils.c: Add new vars demangle and asm_demangle, and let them
3846 (fputs_demangled): If !demangle, just print the argument.
3847 (fprint_symbol): If !demangle, just print raw symbol.
3848 * valprint.c (val_print): Call print_address_demangle rather than
3849 print_address, to cause demangling to depend on the global
3850 rather than assembler-level demangling setting.
3851 * WHATS.NEW, gdb.texinfo: Document.
3853 * main.c (show_command): Show all settings if no arg.
3854 (initialize_main): Make "info set" the same as naked "show".
3855 * command.c (cmd_show_list): Handle prefix commands in the
3856 list, and print the name of the setting as well as its English
3857 description and value.
3859 Allow gdb functions to specify where a line should wrap if it
3860 exceeds the size of a terminal line. Use it to make the output
3862 * utils.c (set_screen_width_command): New fn, mallocs a buffer
3863 of the right size when screen width changes.
3864 (set_screensize_command, screensize_info): Remove #if 0'd fns.
3865 (wrap_here): New fn, indicates a point in the output where we
3866 should wrap the line rather than just letting it overflow at a
3868 (fputs_filtered): Implement wrapping.
3869 (n_spaces): New fn, returns a pointer to N spaces.
3870 (print_spaces_filtered): Use n_spaces.
3871 * defs.h (n_spaces): Declare.
3872 * stack.c (print_frame_info): Wrap with 4-space indent after
3873 fn name and before filename and line number.
3874 * printcmd.c (print_frame_args): Wrap with 4-space indent
3875 before each argument name is printed.
3876 * valprint.c (value_print): Wrap with no indentation before
3878 (val_print_fields): Wrap with indentation relative to nesting
3879 level before each field name.
3880 (val_print): Wrap with nesting indentation before array elements.
3881 * command.c (do_setshow_command): Avoid extra newlines,
3882 wrap with 4-space indent around values printed, end with period.
3883 * WHATS.NEW, gdb.texinfo, gdb-int.texinfo: Document.
3885 * breakpoint.c (breakpoint_1): Implement addressprint for
3886 "info breakpoints" display. Change file name and line number
3887 format to " at file:nnn" rather than " (file line nnn)".
3888 * gdb.texinfo: Document.
3891 Fri Jan 18 07:21:25 1991 John Gilmore (gnu at cygint.cygnus.com)
3893 Frozen for gdb-3.92.6 release.
3895 README, WHATS.NEW: Update for 3.92.6 release.
3897 tconfig/{altos, i386v, i386v32, m88k, umax}: Eliminate
3898 coffread.o from configs since it is now built by default.
3899 tconfig/{3b1, altosgas, arm, convex, hp300bsd, hp300hpux,
3900 i386v-g, i386v32-g, isi, merlin, news, news1000, np1, pn,
3901 pyramid, symmetry, vax, vxworks68}: Eliminate dbxread.o
3902 from configs since it is now built by default.
3904 Makefile.dist: Update for release 3.92.6. Handle files that
3905 have been moved to ../include, ../getopt, or ../bfd. Add
3906 saber.suppress and tests directory. Add config.status to
3907 the release (it will say "none").
3909 coredep.c: Minor formatting fixes.
3911 These changes were made in early December but only checked in now:
3912 * nindy-share/Onindy.c, nindy-share/coffstrip.c,
3913 nindy-share/nindy.c: lint
3914 * nindy-share/nindy.c (ninStopWhy): Don't byteswap the
3915 register values coming back from the target; we store values
3916 in target byte order everywhere.
3918 Wed Jan 16 19:01:37 1991 John Gilmore (gnu at cygint.cygnus.com)
3920 * am29k-opcode.h, am29k-pinsn.c: Add 29050 opcodes.
3922 * valprint.c (cplus_val_print, val_print_fields): New functions,
3923 which print C++ objects. They conspire to avoid printing a
3924 virtual base class more than once, following all the twists and
3925 turns of C++ virtual base rules.
3926 (val_print): Call the above rather than do it by hand.
3928 * symfile.c (symbol_file_add): Only reset symfile_mtime for main
3929 symbol file, not for added files like shared libs. This really
3930 needs to be generalized to a timestamp per file.
3932 * core.c (cleanup_core): Avoid coredump if no core file.
3934 * config.gdb: Accept -host or -target in place of +host or
3937 * coffread.c (find_linenos): Avoid desupported BFD interface
3938 to line numbers. We still read them manually rather than using
3939 BFD's "generic" features.
3941 * gdbrc.tex, threecol.tex: Add GDB reference card and its
3943 Makefile.dist: Add refcard to OTHERS list for creating tar files.
3945 * Makefile.dist: Eliminate use of $< in explicit targets.
3947 * readline/Makefile: Use $< rather than $*.c, which does not
3948 include the VPATH in GNU Make.
3950 * tconfig/i960-bout, tconfig/i960-coff: These are identical
3951 copies of tconfig/i960, added for global configuration
3952 compatability. All i960 versions can read both coff and b.out.
3954 * tm-88k.h: Fix multiline macro that lacked \'s. Remove
3955 COFF_FORMAT and COFF_CHECK_X_ZEROES since these are now handled
3958 * TODO: Think of more things to do.
3960 Wed Jan 2 19:09:29 1991 John Gilmore (gnu at spiff.cygnus.com)
3962 tconfig/{am29k,i960,sun2*,sun3*,sun4*}: Eliminate config
3963 of sdb versus dbx debug symbols. Add kludge for 68881 80-bit to
3964 64-bit float conversion.
3966 tconfig/sun4, tconfig/sun3, xconfig/sun4, xconfig/sun3: Make
3967 equivalent to sun?os4 so global config works.
3969 Wed Jan 2 18:20:51 1991 John Gilmore (gnu at spiff.cygnus.com)
3971 Fix from Eberhard Mattes <mattes@azu.informatik.uni-stuttgart.de>
3973 * main.c: Only declare linesize once; declare pagesize not at
3974 all, since it is never used.
3975 (main): Clear newly allocated line before it is used.
3977 Fri Dec 28 00:13:42 1990 John Gilmore (gnu at cygint)
3979 Further stabilization for the Intel 960.
3981 * Makefile.dist: Parameterize the location of the "include"
3982 and "bfd" directories, as well as "getopt". Add symfile.c.
3983 Link in both dbxread and coffread. Fix up "make depend" to
3984 rewack the locations of include, bfd, and getopt in its output.
3986 * README: Document moving include files, improve some of
3989 * coffread.c: Move common code out to symfile.c. Change
3990 symbol_file_command style interface to use new *_symfile_init
3991 and *_symfile_read interface under BFD. Use BFD internal
3992 info to locate line table, symbols, etc.
3994 * core.c (core_fetch_registers): Rename to get_core_registers
3995 to avoid confusion with fetch_core_registers.
3996 (register_addr): Move to coredep.c, which is already machine
3997 dependent. This leaves core.c pretty clean of dependencies.
3999 * coredep.c (register_addr): Accept this routine from core.c.
4001 * dbxread.c: Move common code (with coffread.c, etc) into new
4002 symfile.c. Each psymtab now contains a pointer to the
4003 format-dependent function that knows how to read it in. Make
4005 (dbx_psymtab_to_symtab): Renamed from psymtab_to_symtab_2.
4006 (process_one_symbol): Add code to complain about a "compiler bug
4007 we muzzle here", if we actually see it.
4009 * eval.c (evaluate_subexp): Insert missing "break" statements
4010 in code that determines whether a variable is an lvalue in
4011 memory, register, or whatever. I detected this via a compiler
4012 bug in which it *almost* mashed out the whole switch statement.
4014 * gdb-int.texinfo: Add minor sections on configuring gdb for
4015 release, and about the README file.
4017 * infcmd.c (registers_info): Fix formatting somewhat. Still
4018 not as pretty as before, but it handles byte swapping.
4020 * remote-nindy.c: If data cache routines are interrupted while
4021 waiting for the remote end, be sure that any uninitialized cache
4022 blocks are on the free list, not on the valid list!
4024 * symfile.h: Flesh out this header file with all the various
4025 routines and variables that have been merged in from dbxread.c
4026 coffread.c, and symtab.c to symfile.c.
4028 * symfile.c: New file, containing code common to dbxread.c,
4029 coffread.c, and some code from symtab.c. All generic code for
4030 reading symbol files should be in here now.
4031 (unrecord_misc_function): Remove unused function.
4033 * symtab.h: Remove file-reading things to symfile.h.
4035 * symtab.c: Remove file-reading things to symfile.c.
4037 * tm-i960.h: Fix FRAME_CHAIN types; define PRINT_RANDOM_SIGNAL
4038 to decode i960 fault types.
4040 * target.h, remote.c, remote-eb.c, remote-vx.c, remote-nindy.c,
4041 target.c: Change type of the "resume" function from int to void,
4042 since its result was never used.
4044 Sat Dec 22 02:51:40 1990 John Gilmore (gnu at cygint)
4046 * main.c: Replace "stupid" with "caution"; you now "set caution
4049 * printcmd.c (print_scalar_formatted): Fix typo in 'g' format
4051 * infcmd.c (do_registers_info): Call val_print to deal with the
4052 byte order of the registers being printed. FIXME, this makes
4053 the formatting of the output uglier.
4055 * infcmd.c (wait_for_inferior): If PRINT_RANDOM_SIGNAL is
4056 defined, call it for signals the debugger doesn't itself use.
4057 The i960 uses this for more detailed fault information.
4059 * remote.c (remote_open): If arg is null, print help rather than
4062 * sparc-xdep.c (register_valid): Avoid declaring size, since
4063 various modules will think of various sizes depending on the
4064 architecture of their tm-file. FIXME, we need protection against
4065 actually entering one of those modules, which would clobber
4066 storage if not for the target architecture compiled into gdb.
4068 * stack.c (up_command, down_command): Always print the frame
4070 (up_silently_command, down_silently_command): New commands
4073 * i960-pinsn.c (reg), i960-tdep.c: Lint.
4075 * i960-tdep.c (i960_frame_chain_valid): Lookup_symbol now takes
4076 more parameters than it used to.
4078 * findvar.c (registers): Increase slop to 256 bytes, which should
4079 protect us against even most RISC machines with large register
4081 (locate_var_value): Move declaration inside related ifdef.
4083 * remote-nindy.c (): Use TIOCSETN rather than TIOCSETP
4084 throughout, to avoid throwing away buffered input from the board.
4085 (nindy_wait): Supply_register takes addr_of_value, not value.
4086 (i960_print_fault): Renamed from i80960_fault.
4087 (nindy_fetch_registers): Avoid have_regs stuff, just get them.
4088 (nindy_store_registers): Avoid regs_changed stuff, just stuff
4090 (nindy_create_inferior): Don't bother to write PC_REGNUM since
4091 we can set the PC in the call to proceed(). Unpush nindy_ops
4092 before pushing it on top, to avoid message to user. Eliminate
4093 commentary from Unix machines that just misleads here.
4094 (reset_command): Fix error message to suggest target command.
4096 Wed Dec 19 11:03:56 1990 John Gilmore (gnu at cygint)
4098 Release 3.92.5 as frozen.
4100 Stabilize the merged release...with help from lint, Saber C,
4103 Everywhere: Add include files needed to declare return types
4104 of functions called.
4106 * gdb.texinfo: Roland Pesch is documenting gdb, glory be!
4108 * breakpoint.h: Add undeclared breakpoint functions, and some
4109 functions for display handling since I couldn't think of a better
4112 * breakpoint.c (insert_breakpoints): Make code for disabling
4113 shared library bkpts more likely to work. It's used when we
4114 rerun a program and stop before the shared library has been
4116 (breakpoint_cond_eval, bpstat_stop_status): Pass arg as int,
4117 cast from pointer, so it squeezes through catch_errors.
4118 (bpstat_stop_status): Fix logic broken some time ago. We now
4119 always create a bpstat if the stop address matches a breakpoint,
4120 even if we don't stop there -- just like the old code used to do
4121 before I got my fingers into it (sigh).
4122 (breakpoint_1): Print "ignore count" after "stop only if"
4123 condition, since that's how it actually works.
4124 (mention): Handle watchpoints as well as breakpoints.
4125 (watch_command): use set_raw_breakpoint and mention to do most
4126 of the work (and initialize all the fields!). Only pass one
4127 arg to parse_c_expression, since that's all it takes.
4129 * command.c (not_just_help_class_command): Rename arg to args
4130 since we ignore "unused argument" warnings on vars named "args".
4131 inflow.c (child_terminal_info): ditto.
4132 infptrace.c (kill_inferior): ditto
4133 main.c (catch_errors, version_info, quit_command, pwd_command,
4134 source_command, dump_me_command, editing_info,
4135 set_history_size_command, set_history, show_history,
4137 stack.c (locals_info): ditto
4138 target.c (target_files_info): ditto
4139 valprint.c (set_input_radix, set_output_radix): ditto
4141 * core.c: Remove old variables for handling core and exec file
4142 sections (data_start, data_end, stack_start, stack_end,
4143 reg_stack_start, reg_stack_end, reg_stack_offset, text_start,
4144 text_end, exec_data_start, exec_data_end, text_offset,
4145 exec_data_offset, data_offset, stack_offset). They're
4146 superseded the more general build_section_table and
4148 (get_exec_file): Mention the `file' command.
4149 (read_memory_check): Rename to memory_error, and only call it
4150 in the case of an actual error.
4151 (read_memory, write_memory): call memory_error.
4152 (core_fetch_registers): Register section name is ".reg".
4154 coredep.c: Remove a bunch of crud now that all this file does
4155 is pull the registers out of a core file.
4156 (fetch_core_registers): Rewrite to actually work, I hope.
4158 dbxread.c: Use a.out.gnu.h, not system a.out, now.
4159 Replace index() with strchr(). Remove all the pre-BFD macro
4160 definitions for accessing the symbol file.
4161 (struct dbx_symfile_info): Encapsulate the information that
4162 dbx_symfile_init needs to pass to dbx_symfile_read in this
4165 (dbx_new_init, dbx_symfile_init, dbx_symfile_read,
4166 dbx_symfile_discard): Rearrange symbol file reading to divide
4167 the format-specific part from the format-independent part,
4168 leaving the format-independent part such as file name expansion
4169 and opening in symtab.c. This replaces
4170 partial_symbol_file_open and partial_symbol_file_read.
4171 Symbol_file_read, add_file, add_file_target_command,
4172 add_file_addr_command move to symtab.c. Pass an explicit
4173 "mainline" flag for when reading the main symbol table, rather
4174 than relying on the offset address to be zero or nonzero.
4176 (dbx_symfile_read): Don't allow void *'s to be printed as
4178 (SWAP_SYMBOL): Use bfd routines to byte-swap the symbols.
4179 (ADD_PSYMBOL_TO_LIST): Make the "function call rather than
4180 macro" debug version really work.
4181 (read_dbx_symtab): Remove unref'd parameter inclink.
4182 Avoid swapping N_SLINE symbols, for speed.
4183 Merge N_TEXT!N_EXT case with the other external symbol
4184 definitions' case. Add comments.
4185 (start_psymtab): Allocate the symfile name in the psymtab on
4186 the psymbol_obstack, rather than using the caller's storage.
4187 (end_psymtab): Only allocate a dependencies list if there are
4189 (psymtab_to_symtab_2): Use BFD when reopening file to read
4190 its symbols for real.
4191 (read_struct_type): Add FIXME comments where it needs work
4193 (read_huge_number): Add FIXME about overflows.
4194 (read_range_type): Add FIXME about comparing a long to 1<<32.
4196 * coffread.c: Minor changes to move things closer to the new
4197 regime with symtab.c and dbxread.c Major work is still needed
4200 * exec.c (exec_file_command): Remove old variables (see core.c
4202 (xfer_memory): If memory transfer is right at the end of a
4203 section, don't lose.
4205 * findvar.c (get_saved_register): If value is in a real
4206 register, LVAL is lval_register, not lval_memory.
4208 frame.h: Declare print_sel_frame and record_selected_frame.
4210 gdb-int.texinfo: New file, for GDB internals documentation.
4211 Very simple, unformatted doc of cleanups is there for now.
4213 gdbcore.h: Remove obsolete variables that described a.out
4214 section addresses and offsets. (See core.c above.)
4215 Declare fetch_core_registers and registers_fetched.
4217 getopt.c: Declare char *alloca(); even on SPARC.
4219 infcmd.c (run_command): Call target_kill rather than
4221 (step_command, next_command, stepi_command, nexti_command):
4222 Declare from_tty parameter even though we don't use it.
4223 (run_stack_dummy): argument BUFFER is a char array, not
4224 a pointer to REGISTER_TYPE.
4225 (finish_command): using_struct_return needed a value *,
4226 not a struct symbol *.
4228 * infptrace.c (child_xfer_memory): To avoid dependency on
4229 where sections are in memory, try PT_WRITE_D and if that fails,
4230 try PT_WRITE_I. Most Unixes don't care which you use.
4232 * infrun.c (step_resume_break_shadow): Change to array to
4233 match other breakpoint shadow storage.
4234 (clear_proceed_status): Pass address of bpstat to
4235 bpstat_clear, not the bpstat itself.
4236 (child_create_inferior): FIXME comment about if the child
4238 (start_inferior): Remove old function.
4239 (child_open): Use target_kill rather than kill_inferior.
4240 (wait_for_inferior): Ditto.
4241 (insert_step_breakpoint, remote_step_breakpoint): Use
4242 new step_resume_break_shadow.
4244 * inftarg.c (child_wait): If all child processes die,
4245 pretend that the one being waited for exited with signal 42.
4247 * main.c (command_line_input): When scanning for comments,
4248 don't coredump on unclosed quotes.
4249 (quit_command): Use target_kill rther than kill_inferior.
4250 (_initialize_main): Rename class_user from "user" to
4253 * printcmd.c (print_command_1): Initialize "fmt" if no format
4254 is specified by the user.
4255 (print_frame_args): Only add to args_printed if we are
4256 actually fetching args from the stack (avoiding undefined
4258 (_initialize_printcmd): Remove bogus \{ from string.
4260 * remote-eb.c (eb_open): Avoid coredump on no argument.
4262 * remote-nindy.c: Bring out of Intel environment into new
4263 target environment. Remove all conditional compilation on
4264 I80960. Massive hacking throughout.
4265 (nindy_xfer_inferior_memory): New routine stolen from
4267 (nindy_create_inferior): New routine pieced together, probably
4268 not quite working yet.
4269 (nindy_ops): New target_ops struct for nindy.
4271 * remote-vx.c: Use write_memory rather than target_write_memory
4272 to get error checking.
4273 (vx_add_file_command, vx_open): Use symbol_file_add rather than
4275 (vx_create_inferior): Use target_terminal_ours...
4277 * signame.c (_initialize_signame): Always initialize, since
4278 we need the table for things other than psignal.
4280 * solib.c (solib_add): Use symbol_file_add, not add_file.
4281 (solib_address): Return boolean result rather than struct
4282 pointer which nobody else knows the type of.
4284 * sparc-tdep.c, valops.c: Use write_memory rather than
4285 target_write_memory, to get error checking.
4287 * stack.c (locals_info, catch_info, args_info,
4288 get_selected_block, frame_command, up_command): Use
4289 target_has_stack, rather than have_inferior_p or
4292 * sun3-xdep.c (fetch_core_registers): Rewrite for new BFD regime.
4294 * symfile.h: New file, defining the interface between the
4295 generic and object-file-specific symbol reading code.
4297 * symtab.c: Move generic symbol-reading interface to symtab.c,
4298 from dbxread.c, coffread.c, mipsread.c, etc. Add symtab_fns
4299 table to map BFD targets to symbol-reading modules in GDB.
4300 Change index to strchr.
4301 (lookup_struct_elt_type): Use error() rather than hand-made
4302 simulations thereof.
4303 (lookup_partial_symbol): Speedup slightly when length == 0.
4304 (symbol_file_add): New function.
4305 (symbol_file_command): Call it.
4306 (symfile_open, symfile_init): New function.
4307 (add_file_target_command, add_file_addr_command): moved from
4310 * target.c (target_command): use target_kill.
4312 * target.h (target_files_info): Don't declare, never called
4315 * tm-sun2.h, tm-sun3.h (STACK_END_ADDR): Use system include
4316 files to determine stack end address.
4318 * valarith.c (value_x_binop, value_x_unop): Change error message
4319 to be more useful. Pass proper argument to value_struct_elt.
4321 * valops.c (value_assign): FIXME comment that long long
4322 bitfields will break here.
4324 * Makefile.dist: Add symfile.h, remote-nindy.c, remote-eb.c.
4325 Update `make saber_gdb' to work better.
4327 * TODO: A woman's work is never done.
4329 * cplus-dem.c, environ.c, inferior.h, infrun.c, inftarg.c,
4330 main.c, obstack.c, printcmd.c, remote-eb.c, remote-nindy.c,
4331 remote-vx.c, remote.c, solib.c, source.c, sparc-pinsn.c,
4332 sparc-tdep.c, sparc-xdep.c, symmisc.c, symtab.c, symtab.h
4333 target.c, terminal.h, tm-sparc.h, tm-sunos.h, utils.c,
4334 valops.c, valprint.c, exec.c: Lint.
4337 Wed Dec 12 23:44:15 1990 John Gilmore (gnu at cygnus.com)
4339 Continuing Intel 960 port merge of GDB.
4341 * Makefile.dist: Merge i960 "nindy-share" files. Rename
4342 malloc.h to gmalloc.h to avoid name conflicts in /usr/include.
4343 Don't ship gdb.dvi in tar file. Link gdb with init.o, not init.c.
4344 Wack over "make depend" so it handles files in subdirectories
4345 vx-share, nindy-share, bfd, and in the current directory.
4347 * blockframe.c (get_prev_frame_info): Remove fatal error
4348 if stack not defined.
4350 * core.c (core_open, core_detach): New functions that handle
4351 the old "core-file" command as "target core" and "detach" instead.
4352 (core_file_command): Call them.
4353 (core_xfer_memory): Use common routine xfer_memory.
4355 * dbxread.c: Include a.out.gnu.h, not system a.out.h.
4356 dbxread now uses bfd for everything but symbol reading itself.
4357 BFD internals are used to drag out the relevant file offsets.
4358 (partial_symbol_file_open): Change args all around for BFD.
4360 * symtab.c: Rename "value" to "val" everywhere, so we can
4362 (symbol_file_command): New command, moved from dbxread.c
4363 and coffread.c. It uses BFD to read the file, then vectors
4364 based on its type, to dbx or coff symbol readers.
4365 * symtab.h: Extern a few vars for symbol_file_command.
4367 * target.h: Breakpoint takes a char * save area, not a char **.
4369 * valprint.c (val_print): When unpacking bitfields, offset
4370 the address in gdb of the value, if it is declared with a shorter
4371 type. Remove the last "runtime kludge test" of host byte order.
4373 * utils.c: Remove old my_bfd_read routine.
4375 * stack.c (frame_info): Use target_has_stack. Print program counter
4376 register's actual name rather than "pc", since it's called the
4377 "ip" (instruction pointer) on the i960 (sigh).
4379 * target.c (target_command): Add command for selecting a target
4380 type and calling its open routine. This is used for initiating
4381 communication with a particular target, in a generic way.
4383 * tm-i960.h: Update for modern gdb. Remove semicolons from
4384 various macros. Handle reading struct return convention, and
4385 error-out attempts to return structs with the "return" command.
4386 Be sure gdb doesn't think we know how to call functions in the
4389 * i960-tdep.c: Rename FRAME_CHAIN_VALID and FRAME_FIND_SAVED_REGS
4390 to i960_xxx in lower case.
4391 (arg_address): Circumvent errors due to LOC_ARG_BLOCK
4392 not being defined yet.
4394 * remote.c (remote_open): Call start_remote to initialize
4395 wait_for_inferior during open.

4405 (wait_for_inferior): Clear saved register values before target_wait,
4406 so target_wait can set some of them if convenient.
4408 * infptrace.c (fetch_inferior_registers, store_inferior_registers):
4409 Return success indicator, not void.
4410 (child_xfer_memory): Avoid fetching initial word if we'll
4411 overwrite it anyway.

4441 * coffread.c (symbol_file_command): Avoid output if from_tty != 1.
4442 Add magic numbers for 960 COFF format.
4444 Fri Nov 30 09:18:20 1990 John Gilmore (gnu at cygnus.com)

4467 Fri Apr 20 13:47:15 PDT 1990
4470 Thu Apr 19 09:54:28 PDT 1990
4471 Add 'reset' command.
4473 Wed Apr 18 09:48:07 PDT 1990
4474 After opening remote tty, wait for 1 second to go by without input
4475 from it before trying to talk to NINDY (fixes problems with the
4476 Heurikon HK80/V960E).
4478 Mon Apr 4 16:33:05 PDT 1990
4479 Some output was not being suppressed in 'batch' mode.
4481 Thu Mar 22 15:31:11 PST 1990
4482 Ask user if old symbol table should be deleted when new file is
4485 Allow user to run a program downloaded before gdb960 was brought up.
4487 Correct "exec-file" help message for i80960 context.

4514 Added 960CA disassembly support.
4516 To simplify maintenance:
4517 - eliminated use of symblic links on pinsn.c: use i960-pinsn.c
4519 - eliminated opcode.h: incorporates tables into i960-pinsn.c
4520 - moved 960-specific routines from i960-pinsn.c to i960-md.c
4521 - made disassembly interface identical to that in gdmp960.
4525 Wed Nov 28 21:32:48 1990 John Gilmore (gnu at cygint)
4527 * target.h: Allow targets to stack. Add target_has_memory,
4528 _registers, etc. Restructure memory access and "info files"
4529 to walk the target stack.
4530 * exec.c, core.c, inftarg.c, remote.c, remote-vx.c, remote-eb.c,
4531 target.c: Change tables to match target.h.
4532 * inflow.c (child_mourn_inferior): pop child_ops.
4533 (generic_mourn_inferior): Use new has_stack flag.

4536 * remote-eb.c: New memory regime, new info files.
4537 * remote-vx.c: New memory regime, new info files. Now use
4538 separate targets for VxWorks attachment to machine, and
4539 actually running a process under VxWorks, since one has
4540 stack & execution & regs and the other doesn't.
4541 * remote.c: New memory regime, new info files.
4542 * sparc-xdep.c (fetch_core-registers): New memory regime.
4543 * target.c: New routines and support for stacked targets,
4544 new memory regime, new info files regime.
4547 Generalize section handling for an arbitrary number of sections,
4548 including use of the new BFD (binary file) library.
4549 * gdbcore.h: Add struct section_table.
4550 * exec.c (build_section_table): Iterate all sections and
4551 record what gdb needs to know about them.
4552 (exec_command): Use it.
4553 (exec_xfer_memory): Use the table.
4554 (exec_files_info): Print the table.
4555 * core.c (core_file_command, core_xfer_memory, core_files_info):

4563 * sparc-xdep.c (fetch_core_registers): Use the .regs info.
4565 * inferior.h (attach_flag): Export.
4566 * infcmd.c (run_command): use new target_create_inferior.
4567 * infrun.c (child_create_inferior): Don't return result.
4568 * Makefile.dist (VERSION): 3.91.4.

4576 * core.c (core_file_command): Display the frame where the core
4581 * remote-vx.c (target_command): Merge in target command from
4582 targ-vx.c. A few other cleanups.
4584 * TODO, Projects: Lots more stuff to do...
4586 Fri Nov 23 18:15:38 1990 John Gilmore (gnu at cygint)
4588 Massive changes to wall off the remote-debugging interface
4589 behind a function vector. The port to handle VxWorks targets
4590 is also part of this.
4592 All files: Replace references to renamed functions,
4593 remove references to remote_debugging, remove references to
4594 have_include_file, have_core_file in favor of target_has_stack,
4595 target_has_memory, etc.
4597 * Modularize the breakpoint interface.
4598 breakpoint.h (BREAKPOINT_MAX): New define sets max length of
4599 a breakpoint instruction.
4600 breakpoint.c: struct breakpoint's shadow_contents now sized as
4602 (insert_breakpoints): Vector to target to install breakpoints.
4603 (remove_breakpoints): Vector to target here too.
4604 Remove REMOTE_SA_SPARC kludges and other remote_debugging.
4605 sparc-tdep.c (single_step): Use new breakpoint interface for
4606 the single-step breakpoints.
4607 mem-break.c (memory_insert_breakpoint, memory_remove_breakpoint):
4608 New file, contains routines to insert and remove breakpoints by
4609 reading out the old contents and later replacing them. This is
4610 how ptrace breakpoints work, and many remote systems as well.
4612 * tm-vxworks68.h: New config file, overrides a few things for
4613 Wind River's preferences.
4615 * target.h: New file, for transfer vector used to talk to the
4616 inferior (child, attached, core, exec, remote, etc). All accesses
4617 to the thing being debugged should come through these vectors.
4618 target.c: New file, routines to handle transfer vector.
4619 (various files): Add transfer vectors XXX_ops for the various
4620 targets and pseudo-targets (core files, etc) we support.
4622 * breakpoint.c (bpstat_stop_status): Further explorations of
4623 watchpoints and why things don't work all the time.
4624 (bpstat_alloc): New fn to allocate a bpstat and chain it.
4626 * config.gdb: Only add "source ${srcdir}/.gdbinit" to
4627 the local gdbinit if it doesn't already have it.
4629 * core.c (core_ops): add and install.
4630 Allow core debugging without exec file.
4632 * dbxread.c (free_and_init_header_files): Merge two fns.
4633 (end_symtab): Free named symbol table when a new version comes in.
4634 (read_dbx_symtab): Relocate all kinds of symbols with base
4635 address. First step toward handling different text, data, bss
4637 (add_file_addr_command): Renamed add_file_command.
4638 (add_file_command): Vector to remote handler.
4639 Add "load" as an alias for "add-file" command.
4641 * defs.h: Allow "volatile" to be used in non-ANSI; use it for
4642 non-returning functions.
4644 * exec.c: Add exec_ops, and push it as a target when an exec
4647 * infcmd.c (run_command): Pass executable file name and arg list
4648 separately when starting an inferior. Permit "run" when no exec
4649 file is specified, for VxWorks.
4650 (detach_command): Move to child_detach in inftarg.c.
4652 * inftarg.c: New file. Unix-child-specific routines, and the
4653 child_ops structure.
4655 * inferior.h (registers): Export "registers" as the way for
4656 target dependent register handlers to find gdb's local copy of
4657 the registers. Rename "stop_after_attach" to "stop_soon_quietly"
4658 since it is now used by places that want wait_for_inferior to
4659 handle the grunge but want to see every trap from the inferior.
4661 * inflow.c (create_inferior): Pull out, and merge into infrun.c.
4662 Eliminate remote_debugging hooks in terminal handling.
4664 * infrun.c: Replace start_inferior with child_create_inferior.
4665 Move all the hair of Unix shells and ptrace idiosyncracies into
4666 child_create_inferior, so remote handlers don't have to deal.
4667 Remove running_in_shell. Rename stop_after_attach to
4668 stop_soon_quietly, and use it in a few other places where we want
4669 to just call wait_for_inferior and get control back on the first
4670 trap. trap_expected now never takes a value > 1.
4671 (init_wait_for_inferior): Initialize static vars when a new
4674 main.c (gdbinit): Add new hook for .gdbinit file name, let
4675 it be overridden by config files as GDBINIT_FILENAME.
4676 (DEFAULT_PROMPT): Add new hook for overriding (gdb) prompt.
4677 Both of these are used for VxWorks gdb.
4679 mcheck.c: rename include file "gmalloc.c" to avoid problems
4680 with system include file "malloc.c".
4682 param-no-tm.h: New include file, same as param.h but does not
4683 include the default "tm.h" file. This is used in files where
4684 the target is known, e.g. remote-eb.c or sparc-xdep.c.
4686 param.h: Now just a shell that includes tm.h and param-no-tm.h.
4688 remote-vx.c: New file, VxWorks remote debugging support. Uses
4689 RPC routines that are shared with the target system, in directory
4692 remote.c: Vectorize remote interface.
4694 source.c: Globalize source_path, and make an alias "l" for "list"
4695 since we now have the "load" command.
4697 sparc-xdep.c: Use new param-no-tm.h.
4699 symmisc.c (free_named_symtab): Add new function from Wind River.
4700 However, ifdef it out for now while we think about what it should
4703 tm-sun3.h, xm-sparc.h, xm-sun3.h, xm-symmetry.h: Move
4705 the xm- file, and change its name to CHILD_PREPARE_TO_STORE, since
4706 non-Unix-children handle this with their own code in the target
4709 Makefile.dist: Roll version to 3.92.3. Add vx-share stuff to
4710 source and target lists. Add vx-share to default list of include
4711 directories. Add new files to src and target lists: mem-break,
4712 target, inftarg, remote-eb, remote-vx, targ-vx. Be sure the
4713 ${srcdir} versions of munch and createtags are used.
4715 * valops.c (find_function_addr): Split out of call_function.
4716 (call_function_by_hand): Rename call_function; this function
4717 calls functions in the target by laboriously patching the target
4718 word-by-word with the right stack, args, regs, etc.
4721 Mon Nov 5 17:29:10 1990 John Gilmore (gnu at cygint)
4723 Handle AMD 29000 a bit better.
4725 * remote-eb.c (readchar): Mask received char log to make it readable.
4726 (remote_start): Pass arguments down to executing program.
4727 Make startaddr unsigned.
4728 infrun.c (start_inferior): Accept args, pass them to
4730 infcmd.c (run_command): Pass args down to start_inferior.
4732 * tconfig/am29k-aout, tconfig/am29k-coff: New files specifying
4733 the target object file format.
4734 tm-29k.h: Pay heed to COFF_ENCAPSULATE.
4736 * am29k-pinsn.c (print_insn): Print 0x on hex numbers in disassembly.
4737 am29k-tdep.c (examine_prologue): Better checking of function prefixes.
4739 Sun Oct 7 18:20:45 1990 John Gilmore (gnu at cygint)
4741 * Makefile.dist (VERSION): Roll version to 3.91.9 and freeze.
4742 * TODO: We did a few things, we have more to do though.

4750 (sparc_frame_find_saved_regs): Simplify and fix what we find.
4751 (sparc_push_dummy_frame): Simplify and fix what we push.
4752 (sparc_pop_frame): Slightly more hair here, deciding whether
4753 we are restoring a saved PC or returning to a return address in %i7.
4754 * sparc-xdep.c (read_inferior_registers): Debug if valid reg is read.
4756 * utils.c (xmalloc, xrealloc): Return type depends on __STDC__.
4757 * symtab.h (xmalloc): ditto, for obstack_chunk_alloc.
4758 * obstack.h (chunkfun): ditto.
4759 * defs.h (xmalloc, xrealloc): ditto
4761 * utils.c (quit): Grab the terminal from the child if necessary.
4763 * inflow.c (term_status_command): Rename to term_info, change
4766 * sparc-pinsn.c (print_insn): Disassembly prefers real instructions.
4767 (is_delayed_branch): Speed up.
4768 * sparc-opcode.h: Add ALIAS bit to aliases. Fix up opcode tables.
4769 Still missing some float ops, and needs testing.
4771 * Support for input and output radixes other than base 10
4772 * defs.h (input_radix, output_radix): Declare.
4773 * expread.y (yyparse, parse_number): Handle changes of input
4774 radix, and ambiguous names-or-numbers in radixes >10.
4775 * printcmd.c (print_scalar_formatted): Print formatted hex
4776 numbers in varying column widths.
4777 * valprint.c (val_print): Use output_format to print scalar ints.
4778 (set_input_radix, set_output_radix, set_radix): Create.
4779 (set_output_radix): Set output_format from output_radix.
4780 (_initialize_valprint): add `set radix' but leave the others off.
4782 * main.c (execute_command): Let stupid questions be turned off.
4783 (_initialize_main): Handle "set stupidity", etc.
4785 * main.c, inflow.c, inferior.h, frame.h, command.c, defs.h,
4786 sparc-pinsn.c, sparc-xdep.c, value.h, valops.c, values.c: Lint.
4788 Tue Oct 2 11:20:02 1990 John Gilmore (gnu at cygint)
4790 * TODO, Makefile.dist, ChangeLog: Freeze for 3.91.8 release.
4791 bfd stuff is still screwed up, but with some manual work, it
4794 * breakpoint.c (bpstat_do_actions): Start over if a command
4795 proceeds the inferior, since the inferior will have stopped and
4796 will need to have its new stop-actions taken care of.
4798 * dbxread.c (read_struct_type): Expression gives Sun3 4.0.3
4799 compiler fits, simplify it.
4801 * gdb.texinfo (directory command): Doc new dir command.
4802 source.c (directory_command): "dir" now puts things on the front
4803 of the path, moves dups up front, and handles multiple names
4804 on the command line, inserting each one in order. It also
4805 blows away cached line and full_filename info.
4807 * stack.c (backtrace_command): Skip "more stack frames follow"
4810 * Change #ifndef HAVE_VPRINTF to #define MISSING_VPRINTF in
4811 xm-convex.h, xm-hp300bsd.h, xm-isi.h, xm-merlin.h, xm-news.h,
4812 xm-np1.h, xm-pn.h, xm-pyr.h, xm-symmetry.h, xm-umax.h, xm-vax.h.
4813 The only odd one was Gould NP1, which had defined vprintf to
4816 * Merge Ted Goldstein <tedg@Eng.sun.com>'s changes for epoch.
4817 printcmd.c (print_command_1): Pass 'inspect' flag down as a global
4818 variable, inspect_it.
4819 valprint.c (print_string, val_print): Use the global inspect_it
4820 to indicate whether to print in Epoch style or normal style.
4822 Mon Oct 1 23:55:26 1990 John Gilmore (gnu at cygint)
4824 * printcmd.c (call_command): add an alias for the "print" command
4825 which runs expressions and doesn't print the result if void.
4826 (print_command_1): implement it.
4828 * command.c: Remove #if 0'd code. Initialize all the fields
4829 in add_cmd (). Rename do_nothing_command to
4830 not_just_help_class_command, and make it externally visible.
4831 command.h: add user_commands to struct.
4832 * main.c (define_command): Don't overload c->function with a char
4833 string as well as a function pointer.
4835 * eval.c (evaluate_subexp): Reinstall tiemann changes to
4836 calling convention of value_struct_elt () that got dropped in
4839 * tm-sparc.h (FRAME_FIND_SAVED_REGS): move to sparc-xdep.c.
4840 sparc-tdep.c (sparc_frame_find_saved_regs): ditto.
4842 * tm-sparc.h (POP_FRAME): replace some constants with defines.
4844 * sparc-xdep.c (store_inferior_registers): defer stores to regs
4845 until a good time (e.g. when we are about to run the child),
4846 saving ptrace calls.
4847 * infrun.c (proceed): handle DO_DEFERRED_STORES.
4848 * tm-sparc.h: define DO_DEFERRED_STORES.
4850 * sparc-xdep.c (store_inferior_registers): when storing float
4851 registers, don't store stack regs too. When storing the SP,
4852 however, DO store the stack regs too. This fixes a bug in which
4853 the dummy frame is not recognized when a call_function finishes,
4854 because its frame pointer (in the stack regs) was never
4856 (read_inferior_registers): Mark WIM and TBR and FPS and CPS valid
4857 even though we don't know how to read them from an inferior.
4858 valops.c (call_function): Comment about storing SP.
4860 * infrun.c (save_inferior_status): Save away the original bpstat
4861 chain so it can be restored later. Install the copied version for
4862 use by whoever saved the status. It will be blow away by
4863 restore_inferior_status, and the original chain restored. This is
4864 important for people who have pointers into the original.
4866 * breakpoint.c, command.h, copying.awk, dbxread.c, defs.h,
4867 findvar.c, frame.h, obstack.h, obstack.c, inflow.c, value.h,
4868 main.c, printcmd.c, sparc-tdep.c, symtab.c, valprint.c: lint
4871 Fri Sep 28 20:32:46 1990 John Gilmore (gnu at cygnus.com)
4873 * Makefile.dist: Roll version to 3.91.8. Add bfd.h and bfdconfig.h
4874 temporarily to the makefile. Add am29k-opcode.h and WHATS.NEW.
4875 Add stuff.c and kdb-start.c to the OTHERS list for tar files.
4877 Fri Sep 28 19:12:12 1990 John Gilmore (gnu at cygint)
4879 * Merge Mike Tiemann's multiple inheritance changes from Sun.
4880 Store the baseclasses in a type struct starting from array element
4881 0 rather than from the unusual array element 1.
4883 dbxread.c: the above.
4884 (virtual_context): Add
4885 Read new debug information about which virtual function table
4886 a virtual function is from, and store it in fn_field.fcontext.
4888 symtab.h: Add fcontextt. Fix baseclass indices. Typo in
4889 TYPE_FN_FIELD_STATIC_P.
4891 symtab.c: the above.
4892 valops.c: the above. Handle pointer casts of object *'s.
4893 (search_struct_method): Add.
4894 (value_struct_elt): First arg is now a pointer to a value, and is
4897 valprint.c: the above.

4899 offsetting to the proper object when calling virtual fns.
4901 (baseclass_addr): Add valuep arg.
4903 * README: Document the current state of BFD config (missing).
4904 * TODO, ChangeLog, Makefile.dist: Roll version.
4905 * WHATS.NEW: Add summary of changes since 3.5.
4907 Thu Sep 27 16:23:12 1990 John Gilmore (gnu at cygint)
4909 * dbxread.c (read_struct_type): Clear bit vectors whenever
4911 symtab.c (B_CLRALL): define.
4913 * tm-sparc.h (STORE_RETURN_VALUE): Avoid clobbering types by
4914 using == rather than =. Huh... This fixes the dreaded problem
4915 wherein builtin_type_int becomes TYPE_CODE_FLT.
4917 * core.c (info_files): Show the inferior pid.
4919 * config.gdb: Avoid putting "dir" command into .gdbinit. GDB
4920 already knows how to look in the source directory.
4922 * Remove psymtab hair from many places. Remove duplicated code
4923 for searching symbol tables. Hide psymtabs from most places.
4924 Make it fast to get from a psymtab to its symtab.
4926 blockframe.c (blockvector_for_pc): Remove psymtab hair.
4927 coffread.c (psymtab_to_symtab): Rename to psymtab_to_symtab2.
4928 mipsread.c (psymtab_to_symtab): Rename to psymtab_to_symtab2.
4929 dbxread.c: export psymtab_to_symtab, make it work if called N times.
4930 (psymtab_to_symtab): Rename to psymtab_to_symtab2. Initialize
4931 new symtab completely. New psymtabs get symtab pointer
4932 initialized to zero. Remove MI warning printf.
4933 symtab.h: Comments. Add psymtab to symtab pointer.
4934 (PSYMTAB_TO_SYMTAB): New macro.
4935 symtab.c: use PSYMTAB_TO_SYMTAB. Add psymtab_to_symtab and export it.
4936 source.c: use PSYMTAB_TO_SYMTAB. Remove symtab version and
4938 stack.c (backtrace_command): Avoid pre-pass to read symbols, if
4940 (print_frame_info): Avoid special-casing symbols that have not yet
4943 * source.c (open_source_file): Quick path if we have already
4944 located the source file by its full name.
4946 * symtab.c (lookup_symbol): Use find_pc_symtab rather than
4947 find_pc_psymtab. When a name is found in the misc function
4948 vector, search the symbol table for its mangled name, not the
4949 name that the user typed.
4951 * bfd.h: Fix missing comment terminators, make #endifs match.
4953 * valarith.c (value_less): Handle unsigned int comparisons.
4954 Add FIXME about pointer compares, which assume host and target
4955 pointers are the same.
4957 * command.c (do_nothing_command): lint
4958 dbxread.c: lint. Remove sort_syms. Document C++ visibility info,
4959 fix comments on debug symbol format for visibility. Actually set
4960 visibility of symbols.
4961 main.c (echo_command): lint; use <readline/history.h>.
4962 tm-sparc.h (FRAME_FIND_SAVED_REGS): lint
4963 obstack.h (_obstack_blank): Rearrange pointer math to avoid
4964 pointing past end of allocated memory; saber complains.
4965 obstack.h: Declare the external functions that we use.
4966 valarith.h: use <string.h>
4967 solib.c (solib_add): lint.
4969 Fri Sep 21 17:05:19 1990 John Gilmore (gnu at cygint)
4971 * main.c (initialize_main): Default info_verbose to off, now that
4972 symbol reading is fast.
4973 (quit_command): Avoid clobbering exec_bfd while quitting.
4975 * Initial BFD (binary file diddling library) merger:
4976 coffread.c: Change AOUTHDR to struct exe_hdr.
4978 core.c: initialize initialized data at compile time.
4979 (core_file_command): Move from coredep.c, convert to bfd.
4980 (xfer_core_file): Convert to bfd.
4981 exec.c (exec_file_command): use bfd routines.
4983 mips-tdep.c: Remove exec_file_command and friends.
4986 * coredep.c: (fetch_core_registers) Convert core_file_command to
4987 fetch_core_registers.
4988 mips-xdep.c, sparc-xdep.c, sun3-xdep.c: ditto.
4990 * utils.c: (error): Bogus crap, FIXME, to print bfd errors.
4991 (my_bfd_read): More bogosity, which I don't think we call.
4992 (program_name): Remove this atrocity asap!
4994 Wed Sep 19 13:36:41 1990 John Gilmore (gnu at cygint)
4997 values.c: allocate_repeat_value was not clearing the
4998 optimized_out field.
4999 (value_static_field): minor stylistic fix (wrong macro was used).
5000 valops.c (value_struct_elt_for_address): didn't work for C++
5003 * signame.c (_initialize_signame): Initialize signal names once.
5005 * breakpoint.h, command.c, copying.awk, defs.h, environ.c,
5006 exec.c, frame.h, infcmd.c, inferior.h, main.c, munch, sun3-xdep.c,
5007 symtab.h, tm-29k.h, valprint.c, value.h, values.c: Lint.
5009 * remote-eb.c: Support user-settable baud rates on the serial port.
5011 * tm-sun3.h (PREPARE_TO_STORE): fix typo.
5013 Fri Sep 14 13:28:29 1990 John Gilmore (gnu at cygint)
5015 * tconfig/sun3os4: Remove warning about native assembler,
5016 since it also occurs in the xconfig file.
5018 * findvar.c (registers): Allocate some slop after `registers'
5019 to prevent stray accesses from trashing the next variable.
5021 * tm-68k.h (REGISTER_BYTES): Allocate the right number of bytes
5022 on the sun-3, by changing the #ifdef from `sun3' (which is not
5023 defined by cc) to `sun'. Symptom was trashed builtin_type_XXX
5024 vars, which happened to follow `registers' in the executable.
5026 * readline/history.c (history_search): Heed gcc-2's advice
5027 and parenthesize && inside ||).
5029 * am29k-opcode.h, am29k-pinsn.c, am29k-tdep.c, remote-eb.c,
5030 tm-29k.c: Insert FSF copyright headers.
5032 * remote-eb.c: Better comments.
5034 * Makefile.dist: Update to 3.91.6.
5035 * TODO: note PREPARE_TO_STORE problem.
5037 Thu Sep 13 09:52:33 1990 Jim Kingdon (kingdon at cygint)
5039 * stack.c (frame_info): Only use FRAME_FIND_SAVED_REGS if defined.
5041 * remote.c: Wrap the whole file in #if !defined (SPECIAL_REMOTE).
5043 * infrun.c (wait_for_inferior, at end): Don't set up
5044 prev_* if the inferior no longer exists.
5046 * inferior.h (CALL_DUMMY_LOCATION): New macro, to replace
5047 CANNOT_EXECUTE_STACK.
5048 valops.c (call_function): Use it.
5050 * tm-convex.h: Add CALL_DUMMY_LENGTH for use by PC_IN_CALL_DUMMY.
5052 * inferior.h (PC_IN_CALL_DUMMY): New macro.
5053 infrun.c (wait_for_inferior, 2 places): Use it.
5055 * values.c (value_being_returned): Only use
5056 EXTRACT_STRUCT_VALUE_ADDRESS if defined.
5058 * Move PREPARE_TO_STORE from xm-sun3.h to tm-sun3.h to do the
5059 right thing for remote-eb.c.
5061 * sun3-xdep.c: Remove extraneous call to remote_store_registers.
5062 * sun386-xdep.c, hp300hpux-xdep.c, sparc-xdep.c: Ditto.
5064 * blockframe.c: Put get_frame_saved_regs inside #if !defined
5065 (FRAME_FIND_SAVED_REGS).
5067 * findvar.c ({fetch,store}_registers): Check for
5068 REMOTE_{FETCH_STORE}_REGISTER macro.
5070 * findvar.c (get_saved_register): Add argument lval and
5071 change meaning of argument addr.
5072 findvar.c: Change calls to get_saved_register to reflect
5073 new calling convention.
5074 valops.c (value_assign): Use get_saved_register instead of
5075 find_saved_register.
5077 Sun Sep 2 12:40:20 1990 Jim Kingdon (kingdon at cygint.cygnus.com)
5079 * coffread.c (read_one_sym): Make temp_aux an AUXENT, not
5080 an (uninitialized) pointer to one. Use "&" when passing it
5083 Fri Aug 31 22:57:54 1990 Jim Kingdon (kingdon at cygint.cygnus.com)
5085 * coffread.c (getfilename): Use DGUX x_offset and x_name if
5088 * coffread.c (symbol_file_command): Put semicolon after
5090 Put safe_to_init_tdesc_context in #if defined (TDESC).
5091 Put #ifdef TDESCs in 1st column for non-ANSI cpp's.
5092 coffread.c: #include <sys/stat.h>.
5093 (read_coff_symtab): Typo: in_source_files -> in_source_file.
5094 Add missing ')' in check for "lc%" and friends. Remove
5096 Declare read_one_sym() at top of file.
5097 (read_file_hdr): Put in extra #ifdefs so MC68MAGIC and
5098 MC68WRMAGIC can have the same value without causing a duplicate
5101 Thu Sep 13 15:55:36 1990 John Gilmore (gnu at cygint)
5103 * Allow a Makefile to be built without building the
5104 tm and xm file links that screw up builds in subdirectories.
5105 This is done with `config.gdb none', then you can do things
5106 like `make gdb.tar.Z'.
5107 * tconfig/none: Config file for no target system
5108 * xconfig/none: Config file for no host system
5109 * config.gdb: If no TM or XM files are called out by the
5110 host or target file, don't make links for them.
5112 * cplus-dem.c: Add documentation.
5114 * dbxread.c (read_ofile_symtab): Turn a fatal error into a
5115 simple error, so the user's gdb doesn't crash due to some object
5116 file problem (e.g. somebody is rebuilding the file out from under
5119 * printcmd.c (print_address_symbolic): demangle the symbol.
5121 * Makefile.dist (OTHERS): Remove tdesc-lib because it has
5122 Motorola copyrights in it. Make "make gdb.tar.Z" work.
5123 (alldeps.mak): sort and uniq all results from this; duplicates
5124 hose gdb.tar.Z link building. Remove RCS files from
5125 tconfig and xconfig. Add config files for sun386. Add
5126 a few odd files to OTHERS and HFILES.
5128 Mon Sep 10 21:20:24 1990 John Gilmore (gnu at cygint)
5130 * Makefile.dist: Pull solib.c to tconfig/sun?os4.
5131 Roll version number to 3.91.5. Make lint work in bindir.
5133 * README: Document cross-debugging and new file structure.
5135 * blockframe.c: Lint. Include "value.h" to declare read_register.
5136 (find_pc_partial_function): remove duplicate line.
5138 * command.h: Lint. Declare error_no_arg and dont_repeat.
5140 * tm-news.h: Remove inadvertently duplicated stuff.
5142 * mipsread.c: Remove cache_pc_function stuff, now done cleanly.
5143 Clean up usage of misc_function_type. Declare some CORE_ADDRs.
5145 * config.gdb: Allow `config.gdb host target' form. Clean
5146 up previous change that printed bogus messages when you just said
5149 * core.c: #include "command.h" for lint.
5152 * main.c: Remove some casts of enums. Lint.
5159 * printcmd.c (initialize_printcmd): Fix thinko in inspect cmd.
5161 * sparc-tdep.c (isannulled): Take instruction as parameter, don't
5162 read it from memory. This will allow us to save ptrace calls
5163 eventually. Changed caller single_step too.
5165 * sparc-xdep.c (fetch_inferior_registers): Avoid reading regs
5166 that we aren't going to use, saving many ptrace calls, especially
5167 when watchpointing or single stepping. Use some #define's for
5169 (store_inferior_registers): Ditto.
5170 (core_file_command): Use some #define's for constants.
5172 * tm-sparc.h: Add #define's for some register numbers, so we
5173 can eliminate the use of random constants in sparc-xdep.c.
5175 * stack.c (frame_command, print_frame_info, up_command,
5176 down_command) Remove frame_changed, since it
5177 causes a bug and doesn't seem to do anything useful. In some
5178 places it was used as a flag, in others as a stack level (?).
5180 * utils.c: Use MISSING_VPRINTF rather than HAVE_VPRINTF, so the
5181 default is to use the portable (vprintf) version rather than the
5183 * xm-news.h (MISSING_VPRINTF): Add.
5185 * valprint.c (val_print): Demangle fancy vtbl printouts. Lint.
5187 Sat Sep 8 00:24:12 1990 John Gilmore (gnu at cygint)
5189 * Remove stuff that forces -Bstatic linking of gdb, and warnings
5190 about linking debugged programs -Bstatic in the sun?os4 config
5191 files in tconfig and xconfig subdirectories.
5193 * main.c (main): Remove unreached exit(0) now that we exit
5196 * Create TODO file for online bug list. There are too many
5197 "little" bugs to keep track of on paper.
5199 * Change Projects file to refer to bug-gdb@cygnus.com
5200 rather than kingdon@ai.
5202 Fri Sep 7 23:35:15 1990 John Gilmore (gnu at cygint)
5204 * Makefile.dist (VERSION): 3.91.4 now.
5206 * symtab.c (init_misc_bunches): Rename from init_misc_functions.
5207 (condense_misc_bunches): Add sanity check that misc_count is
5208 the same as the number of symbols in the bunch.
5210 * coffread.c: rename init_misc_bunches. Pass an argument
5211 to condense_misc_bunches (a zero).
5213 * dbxread.c (partial_symbol_file_read): Call init_misc_bunches
5214 every time we are called; don't rely on our caller to do it.
5215 (add_file): Remove call to init_misc_bunches.
5217 * mipsread.c: Only warn, don't error, if unknown symbol types.
5218 This keeps an old gdb from falling on its face if it sees newly
5219 extended symbol info. Rename init_misc_bunches.
5221 Fri Sep 7 22:58:15 1990 John Gilmore (gnu at cygint)
5223 * Merge in changes from Per Bothner for DECstations and other
5224 MIPS stuff. The rest is Bothner speaking:
5226 The next message is a merger of Alessando Forin's mips port with
5227 mine. I've tried to use my good if biased judgment to get
5228 the best of both. It *does* need testing.
5230 Some of the changes are general, *not* mips-specific.
5233 Didn't believe in little-endian bit order.
5234 There are still inconsistencies about whether flags
5235 like BITS_BIG_ENDIAN are integer (#if ...) or
5236 boolean (#ifdef ...). I tried to paper over them.
5238 dbxread.c,coffread.c,mipsread.c,symtab.c,symtab.h:
5239 Moved some misc_function code that was common to
5240 {dbx,coff,mips}read.c to symtab.c.
5241 In the process, I think I cleaned things up a bit.
5242 At the same time, moved obsavestring and obconcat to symtab.c.
5245 Removed obsolete condense_addl_misc_bunches (use
5246 condense_misc_bunches(1) instead).
5249 Needed to include <sys/dir>, at least on DECstations.
5251 valops.c, mips-tdep.c, tm-mips.h:
5252 Added PUSH_ARGUMENTS macro to support funny argument-pushing
5253 conventions (when STACK_ALIGN is insufficient).
5254 Needed on mips, where doubles need 8-byte alignment,
5255 but ints only need 4.
5258 Removed cruft that was not being used.
5259 Merged in many fixes (most from Frank Yellin, fy@lucid.com).
5262 Print $ before register-names (I think that makes things a little
5264 Never print two instructions, even if one delays.
5265 Removed hex-disassemble set_cmd. (This is not mips-specific,
5266 so I think the argument is whether it is generally worthwhile or not.
5267 I'm inclined to think not, given how easy it is to
5268 convert between radixes in gdb.)
5271 This is basically Alessando's code.
5272 It doesn't use obstacks; I changed it to use obstacks
5273 in a few minor places where using malloc causes a
5274 memory leak. (Probably, more places could/should be changed.)
5275 I added record_misc_function where it was missing.
5276 In symbol_file_command and add_file_command, I tried
5277 to make the code consistent with more recent versions.
5278 Minor sylistic changes in parse_procedure.
5279 Make a .gdbinfo. psuedo-symbol point back to the real
5280 procedure symbol (using the isym field).
5283 This is basically from my port, but with a lot of details
5284 and a number of routines merged in from Alessando's version.
5285 I basically used my code "raw" backtrace (use heuristics
5286 from the actual code, rather than symbol table info) - though
5287 the idea is Alessandro's. I feel my code is a little cleaner
5288 here, particularly in being a little more flexible, such as being
5289 able to handle gcc-produced code (which it now can).
5290 It also doesn't do frame caching (which is not useful
5291 more recent gdb versions).
5292 I also used my code for push_/pop_dummy, more or less.
5293 I tried to incorporate AF's code for testing sigtramp
5294 while backtracing; I probably got it wrong.
5295 Added mips_print_register, which tries to scrunch as much
5296 information as possible on a screen...
5297 Removed the skip-prologue set_cmd. As with hex-disassemble (see
5298 under mips-pinsn.c), I don't see anything mips-specific here,
5299 and I don't see it being all that useful anyway.
5302 Added a $fp psuedo-reg distinct from $fp (nice for gcc).
5303 Use more register names (rather than hard-cases numbers).
5305 Thu Sep 6 18:33:15 1990 John Gilmore (gnu at cygint)
5307 * Hack up 3.90.11 changes:
5309 * Makefile.dist (depend): parameterize $(GCC).
5310 Add solib.c and solib.o.
5311 (readline): Fix vpath for both absolute or relative SRCDIR.
5313 * blockframe.c: Fix from Schaefer@asc.slb.com for shared libs.
5314 Also, let the part I didn't understand at least compile so
5315 I can test the rest. FIXME.
5317 * dbxread.c: Fix thinko using strcmp.
5318 (init_psymbol_list): declare static.
5319 (partial_symbol_file_open): Comment cleanups better, avoid
5320 cleaning up the string table since the caller will do that.
5321 Move the stat for mod time into symbol_file_command, temporarily.
5322 (There should be a mod time for each symbol file, eventually,
5323 to control its rereading. FIXME.)
5325 * infptrace.c (PT_WRITE_D): use same value as PT_WRITE_I for
5326 SunOS, which gives error for shared libs otherwise. (From
5327 Schaefer, probably FIXME needs work for portability.)
5329 * solib.c: Move #include "param.h" to work.
5330 Lowercase all the Uppercase Letters In the Messages.
5331 (find_solib): Clean up inferior_so_name for debug printouts.
5332 Allow no argument, to mean all shared libraries.
5334 * symmisc.c: include param.h to get CLEAR_SOLIB.
5336 Wed Sep 5 18:00:08 1990 John Gilmore (gnu at cygint)

5382 Take code which is shared between symbol_file_command and
5383 add_file_command and put it into partial_symbol_file_{open,read}.
5384 Split add_file_command into add_file_command and add_file.
5385 Make psymtab_to_symtab read in the string table if the file
5387 Two new parameters to read_dbx_symtab and start_psymtab.

5441 * Makefile.dist: Bump version to 3.91.3.
5443 * Clean up handling of breakpoint commands (somewhat).
5444 Prompted by Tiemann bug report "cont 10" doesn't work any more.
5446 inferior.h: Add breakpoint_proceeded to inferior status struct
5447 and globals; save it and restore it.
5448 (clear_breakpoint_commands): Cleanup, remove old #define.
5450 infrun.c (clear_proceed_status): Set breakpoint_proceeded.
5451 (save_inferior_status, restore_inferior_status): handle it also.
5452 (proceed): Remove earlier code that set breakpoint_proceeded.
5453 It is now set only in clear_proceed_status.
5454 (clear_proceed_status): Cleanup, use bpstat_clear rather
5455 than clear_breakpoint_commands. No callers need the stop_bpstat
5456 between clear_proceed_status and proceed.
5458 infcmd.c: Add breakpoint_proceeded definition and comment.
5459 (cont_command, jump_command, signal_command): Move call to
5460 clear_proceed_status right next to call to proceed.
5462 breakpoint.c (bpstat_do_actions): Avoid clobbering our
5463 caller's argument while running down the chain of breakpoints.
5464 Use new variable "breakpoint_proceeded" to determine when
5465 a command that it executes moves the inferior past the
5467 (bpstat_clear): Handle NULL argument.
5468 (bpstat_clear_actions): Avoid useless call to
5469 breakpoint_auto_delete.
5470 (delete_breakpoint): Clean up bpstat's that are pointing to
5471 the deleted breakpoint from the stop_bpstat chain.
5472 (breakpoint_auto_delete): Simplify.
5474 * Clean up handling of EOF, error on stdin, etc. This was
5475 prompted by a network problem that caused gdb to go into an
5476 infinite loop filling up its malloc'd memory.
5478 main.c (return_to_top_level): Cleanup: call bpstat_clear_actions,
5479 not clear_breakpoints_commands, which is now gone.
5480 (main): If command_loop returns (e.g. from EOF on stdin), do
5481 a quit_command (looping back to command_loop if quit_command
5482 doesn't really quit).
5483 (command_loop): check result from command_line_input and
5484 exit if it returns NULL, rather than passing the NULL to
5486 (gdb_readline): Free malloc'd result space before returning
5489 * utils.c (query): Handle C-d to mean "yes", just as if the
5490 input was not a terminal. Also avoid infinite loop if EOF
5491 occurs in mid-input-line before newline. This allows
5492 query to be used at EOF on stdin with reasonable results.
5494 * infrun.c (proceed): Set breakpoint_proceeded.
5496 * values.c (value_as_long): Avoid infinite recursion for enums.
5497 (_initialize_values): Fix typo in help msg (kingdon).
5499 * Makefile.dist (RL_LIB): Use RL_LIB_DEP for dependencies,
5500 RL_LIB for linking. This allows -lreadline for linking
5501 and nothing for dependencies, once readline is a real library.
5503 * config.gdb: Jim Kingdon: give useful error message if the
5504 host or target type is not recognized.
5506 * defs.h (alloca): SPARC <alloca.h> does not declare alloca,
5507 it just defines it. Dumb, but deal with it.
5509 * Jim Kingdon suggests:
5510 in xconfig/sun3os4, CFLAGS should be XM_CFLAGS.
5512 Wed Aug 29 18:03:27 1990 John Gilmore (gnu at cygint)
5514 * Makefile.dist (VERSION): Bump version # to 3.91.2.
5516 * Clean up Bothner's changes.
5518 * blockframe.c (clear_pc_function_cache): New function.
5519 * blockframe.c: remake cache_pc_function_* static.
5520 * dbxread.c (symbol_file_command): remove references to
5521 cache_pc_function_* variables.
5522 * dbxread.c (read_struct_type): Use VOFFSET_STATIC.
5523 * printcmd.c: Avoid kludging a global variable (addressprint)
5524 to avoid printing the address of a string twice. Instead,
5525 pass the format letter 's' down low enough that it can be seen
5526 to avoid this problem.
5527 (print_formatted): Pass format arg to value_print.
5528 (restore_addressprint): Remove function.
5529 (do_examine): Avoid hacking addressprint, cleanups and such.
5530 (print_frame_args): Add a comment to a Bothner change.
5531 * symtab.h: define VOFFSET_STATIC and use it instead of "-1".
5532 * symmisc.c (free_all_symtabs): Call clear_pc_function_cache
5533 to wipe out the values cached in blockframe.c.
5534 * symtab.c (find_method): Add comment saying how big you must
5535 allocate to be "big enough". Per being terse again.
5536 * valprint.c (val_print): Handle format letter "s" to print
5537 strings without addresses. Add comment to vtbl printing code
5538 which casts with wild abandon. Rearrange reference-printing
5540 @0xaddr: value (print w/addressprint)
5541 value (print w/~addressprint)
5542 @0xaddr (parameter lists w/addressprint)
5543 or nothing (parameter lists w/o addressprint)
5545 Tue Aug 28 10:47:18 1990 John Gilmore (gnu at cygint)
5547 * Merge more changes from Per Bothner:
5549 Gdb's handling of TYPE_CODE_REF was so counter-C++ (and otherwise
5550 annoying) that I tried to improve it. Here are my suggestions.
5552 These patches all attempt to handle TYPE_CODE_REF (as in C++) better.
5555 Do automatic de-reference when taking the address of a reference.
5557 Don't deref_ref when printing parameter lists.
5559 More attempts at treating refernences properly.
5561 In val_print, if deref_ref==0, don't print dangling " = ".
5563 Add COERCE_REF macro, which de-references an REF.
5565 * Merge changes from Per Bothner:
5567 * Fixed (Sony news)-specific configuration problems.
5568 * Fixed other problems with using vanilla pcc and libc (enum problems;
5569 assumption that vsprintf exists).
5570 * Some major speed-ups (finc_pc_partial_function now caches a match;
5571 parsing avoids duplicate symbol_lookup calls).
5572 * Changed handling of baseclasses (no longer use baseclasses field
5573 of struct type, use the first n_baseclasses fields instead).
5574 * Various minor changes/fixes, most C++-related.
5577 Cache the most previous match from find_pc_partial_function.
5578 (Save both low and high ends of matching function's pc range.)
5579 This speeds up the loop of infrun.c:wait_for_inferior quite
5580 a bit, and makes step/next commands much zippier.
5582 Added an enum->int cast (otherwise, some compilers barf).
5584 No longer set baseclass offset to 0, since multiple
5585 inheritance now mostly works.
5586 Added a number of casts, to shut up compiler warnings
5587 (after stabs where made enums, not ints).
5588 When discarding a symbol table (in symbol_file_command),
5589 must clear the cache introduced in blockframe.c.
5590 Don't convert $vtbl_ptr_type to vtbl any more.
5591 Get rid of TYPE_BASECLASEES and baseclass_vec (see also symtab.h).
5592 Mask off sign bit emitted by g++ for virtual table offset.
5593 Set voffset to -1 (not 1) for static member functions.
5595 Changed parsing/lexing of names to avoid doing symbol lookup twice
5596 (once when lexing to determine symbol class, once for real).
5597 Now only call symbol_lookup once. Fields of 'this' win especially big.
5599 Subpress printing addr twice in the case of 'x/s addr'.
5601 lookup_basetype_type is no longer used.
5602 Add find_methods as recursive helper function to decode_line_1.
5603 This allows multiple inheritance to work.
5604 Also, once one or more matches has been found, do not look in
5605 base-classes. (Baseclass methods would be overridden, anyway.)
5607 Removed baseclasses array in struct type.
5608 Instead of using baseclasses[i], use fields[i-1].
5609 Added virtual_field_bits[i] to indicate if the i'th baseclass is virtual.
5610 Changed sign convention of voffset (previous was inconsistent).
5612 Some macros (CALL_DUMMY and relatives) were missing. Put them back.
5614 Used to assume existence of vsprintf. Re-written to not need it
5615 if HAVE_VPRINTF is undefined.
5617 typecmp was too pessimistic. Made it less so.
5619 Don't print space after address.
5620 If vtable points to a misc symbol (with 0 offset), print it,
5621 since that indicates the actual class of the object.
5622 Changed ype_print_derivation_info to use new inheritance
5623 scheme (without baseclasses vector).
5625 In value_primitive_field, fixed some bugs left over from previous set of fixes.
5626 Also, changes needed because TYPE_BASECLASSES were removed.
5628 REGISTER_U_ADDR didn't work for PC. Rewrote to use an array.
5630 Tue Aug 21 20:08:54 1990 John Gilmore (gnu at cygint)
5633 If there is no path set, and the symbols don't indicate what directory
5634 a file was compiled in, look in the current directory. But either
5635 a path or a known compilation directory will prevent this.
5638 Three independent bug fixes:
5639 * Remove the #if 0 block that breaks some stuff.
5640 * SunOS 4.1 fixed the promoted-parameter-wrong-addr bug in Sun C;
5641 adapt gdb to either SunOS 4.0.* or 4.1.
5642 * MAX_OF_TYPE and MIN_OF_TYPE thinko. By tedg@sun, I think.
5645 Instantiate the class T when looking for methods in it. (Tiemann@sun)
5648 (type_print) Demangle the name being printed.
5649 (type_print_base) Handle botched demangling without coredump (tiemann).
5652 (check_stub_method): Document routine.
5653 (tiemann) fix bug for no-arg functions
5654 Avoid clobbering beyond end of malloc'd storage.
5655 Terminate the argument list properly.
5657 Sat Aug 18 01:29:59 1990 Per Bothner (bothner@cs.wisc.edu)
5659 * Changes merged by John Gilmore:
5662 In breakpoint_1, use new print_address_symbolic instead
5663 of find_pc_partial_function. (This forces use of assembler-level
5664 addresses, and avoids misleading non-mangled source-level names.)
5666 Generalize ansi argument such that -1 means skip arglist totally.
5667 Removed global variable print_ansi_qualifiers (which made
5668 code non-reentrant), in favor of extra explicit arguments
5669 to internal routines.
5671 Add new helper function print_address_symbolic.
5672 Use find_pc_misc_function instead of find_pc_partial_function
5673 (since we want assembler-level symbols here).
5675 Print unknown function as just "f (...)", not "f (...) (...)".
5676 Use new fputs_demangled explicitly.
5678 Fixed a typing violation (problem: value.h cannot be imported
5679 without renaming many variable in this file).
5680 lookup_symbol: If no matching misc_func, look for a C++-mangled name.
5681 decode_line_1: Moved forward some never-reached code.
5682 Made decode_line_2 skip function prologues correctly.
5684 fputs_filtered should not demangle by default.
5685 Add new fputs_demangled to demangle on demand..
5687 Change value_struct_elt to use value_primitive_field (using recursive
5688 utility function search_struct_field). This allows foo.bar to work
5689 for multiple inheritance (so far only for data fields).
5690 Change check_field in the same way (recursive helper function
5691 to support multiple inheritance).
5692 (Note: there are more of these problems that I haven't fixed.
5693 Any code that says TYPE_BASECLASS (t, 1) is probably wrong.)
5694 value_of_this: 'this' symbol name is now just "this", note "$this".
5696 Don't print static members.
5697 Avoid printing "members of <type>" if there are none.
5698 Simplified type_print_derivation_info by merging duplicate code.
5699 Remove useless blank lines in type_print_base (ptype command).
5701 Added declaration of new routine value_primitive_field.
5703 Added value_primitive_field which is generalized version of
5704 value_field that can handle multiple inheritance (non-zero offsets etc).
5705 Re-implemented value_field to call value_primitive_field.
5707 Fri Aug 17 23:33:44 1990 John Gilmore (gnu at cygint)
5709 * infcmd.c -- insert else to avoid 'delete env' coredump when you
5710 delete the whole environment. Karl Berry reported the bug.
5711 * source.c - fix openp to avoid //'s in filenames, which
5712 trigger an Emacs bug causing it to not be able to find files
5713 when running gdb in a window.
5714 * dbxread.c - zap the #if 0 that botches the add-file code.
5715 It seems to work a lot better without all the code commented out.
5717 Fri Jul 20 16:58:46 1990 John Gilmore (gnu at cygnus.com)
5719 * Merge Tiemann's and Ted Goldstein's changes, detailed below,
5722 Tue Jul 17 19:34:33 1990 Ted Goldstein (tedg at golem)
5724 * Makefile - added a ${CFLAGS} to a couple of entries,
5725 added remote-sa.sparc.c
5726 * added remote.sa-sparc.c, a modification of remote.c
5727 which conducts a dialog directly with the SparcStation prom.
5728 * breakpoint.c, infrun.c, sparcdep.c added
5729 remote_insert_breakpoint(), and remote_remove_breakpoint()
5730 to breakpoint.c instead of directly writing breakpoint instructions.
5731 * sparcdep.c on remote_debugging,there is no need
5732 to remove signle step breakpoint instructions.
5733 * main.c added "-epoch" flag and "int epoch_interface" to main.c
5735 * printcmd.c - epoch interface sends lisp expressions to open up
5736 epoch windows on inspection.
5737 * valprint.c - added arrayprint, and addressprint and made adding
5738 format controls easier
5739 * wait.h added a couple of undef's because we were getting
5740 complaints about WSTOPSIG and WTERMSIG begin redefined.
5743 Wed Jul 4 05:27:51 1990 Michael Tiemann (tiemann at masham)
5745 * symtab.c (decode_line_1): Add support for handling method stubs

5750 * values.c (baseclass_addr): Run loop from INDEX+1 to
5751 N_BASECLASSES; otherwise, we can still get into a loop.
5752 @@ This should be restructured to use a cleaner search strategy.
5754 Sun Jul 1 12:28:51 1990 Michael Tiemann (tiemann at masham)
5756 * dbxread.c (define_symbol,read_type): Grok GNU C++'s new
5757 abbreviation "Tt" for tags which have the same name as their
5760 Fri Jun 29 01:03:46 1990 Michael Tiemann (tiemann at masham)
5762 * symtab.c (list_symbols): add ability to set breakpoints on all
5763 the functions which match a particular regular expression.
5765 Tue Jun 26 04:26:29 1990 Michael Tiemann (tiemann at masham)
5767 * cplus-dem.c (cplus_demangle): New parameter ANSI says whether we
5768 should print ANSI qualifiers (such as `const' and `volatile').
5769 All callers changed to call with ANSI == 1, except from
5770 `check_method_stub', which uses old-style syntax.
5772 * symseg.h (struct fn_field): Remove unneccessary `args' field.
5773 * symtab.h (TYPE_FN_FIELD_ARGS): Redefined.
5775 * values.c (check_stub_method): New function.
5777 * cplus-dem.c (do_type): Handle "long long" (encoded as 'x').
5779 * dbxread.c (read_type): Handle new GNU C++ method type stubs.
5780 * valprint (type_print_base): Ditto.
5782 * symtab.c (gdb_mangle_typename): New function.
5784 Tue Jun 5 00:18:43 1990 Michael Tiemann (tiemann at gzilla)
5786 * breakpoint.c (catch_command): New function. Provides a
5787 mechanism to set breakpoints based on catch clauses.
5788 (disable_catch): Similar, but disables breakpoints on catch
5790 (delete_catch): Similar, but deleted breakpoints on catch clauses.
5792 Sun Jun 3 22:54:08 1990 Michael Tiemann (tiemann at gzilla)
5794 * blockframe.c (blockvector_for_pc): New function.
5795 * blockframe.c (block_for_pc): Changed to call
5796 `blockvector_for_pc' and get the block itself.
5798 * stack.c (catch_info): New function. Prints info about
5799 exceptions which can be caught in the current frame.
5800 * stack.c (print_frame_label_vars): New function. Similar to
5801 `print_frame_local_vars'.
5802 * stack.c (print_block_frame_labels): Prints out labels that are
5803 defined in this frame. These labels are exceptions that can be
5806 * dbxread.c: Updated to handle N_CATCH symtab types.
5808 Thu May 3 22:10:00 1990 Michael Tiemann (tiemann at teacake)
5810 * valprint.c (everywhere): TYPE_NAME (TYPE) no longer comes in the
5811 form "struct ..." for GNU C++. Don't flush any part of TYPE_NAME
5812 when printing the type.
5814 Wed May 2 22:43:04 1990 Michael Tiemann (tiemann at teacake)
5816 * valprint.c (val_print): Use `baseclass_addr' to access the
5817 baseclasses pointed to via the derived class object at VALADDR.
5819 * values.c (baseclass_addr): New function. Casts derived pointers
5820 to baseclass pointers taking virtual baseclasses and multiple
5821 inheritance into account.
5823 Sat May 5 12:39:18 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5827 Fri May 4 12:12:55 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5829 * breakpoint.c (watch_command, bpstat_stop_status): Deal with
5830 exp_valid_block field correctly.
5832 * infrun.c (wait_for_inferior): When checking "don't even think
5833 about breakpoints" if stop_signal == SIGTRAP && trap_expected,
5834 also check step_resume_breakpoint.
5835 Insert breakpoints and continue (not step) if
5836 step_resume_break_address != NULL, even if another_trap.
5837 If trap_expected and we enter sigtramp, then set up a
5839 If trap_expected is set when we hit the step_resume_break,
5841 When calling resume and trap_expected says tell resume to step
5842 (2 places), also check step_resume_break_address.
5844 * infrun.c (wait_for_inferior): Don't set
5845 prev_{pc,sp,func_{start,name}} before calling wait ().
5846 Do set them after exiting loop.

5850 Thu May 3 00:15:11 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5852 * infrun.c (wait_for_inferior, after check for trap_expected > 1):
5853 Restore old code which distinguishes between trap_expected and
5854 running_in_shell, just make the latter take any non-TRAP signal,
5857 * values.c (allocate_value): Zero VALUE_OPTIMIZED_OUT flag.
5859 * Makefile.dist (pinsn.o): Use PINSN_CC to compile.
5860 xconfig/3b1 (CC,PINSN_CC): Define.

5881 * valprint.c (value_print): Check VALUE_OPTIMIZED_OUT flag.
5883 * value.h: Add optimized_out field and change lazy field to
5884 char. Add macro VALUE_OPTIMIZED_OUT.
5886 * i386-pinsn.c: Change from Eirik Fuller to write to stream directly
5887 instead of stuffing things in buffers (oappend, etc).
5889 * breakpoint.c (bpstat_do_actions): If *BSP is set to NULL by
5890 execute_command, exit both loops.
5892 * Makefile.dist: Don't set TARGET_ARCH. Add .c.o rule.

5919 findvar.c (get_saved_register): New function.
5920 findvar.c: Rewrite code which called find_saved_register to
5921 call get_saved_register instead.
5923 Sun Apr 22 14:47:51 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5925 * valprint.c (val_print): Change error message printed when

5963 m-m88k.h: Use INIT_{FRAME_PC,EXTRA_FRAME_INFO} to do tdesc stuff.
5964 Use dummy versions of FRAME_CHAIN_*.
