1 Fri Oct 25 02:02:13 1991 John Gilmore (gnu at cygnus.com)
3 * core.c (core_file_info), exec.c (exec_file_info): Print file
4 type. Use printf_filtered.
6 * valops.c (value_fetch_lazy): Avoid 0-length fetches.
8 Thu Oct 24 23:06:40 1991 Fred Fish (fnf at cygnus.com)
10 * dwarfread.c: Add casts to remove compiler warnings.
12 * tm-3b1.h, tm-68k.h, tm-altos.h, tm-amix.h, tm-hp300bsd.h,
13 tm-hp300hpux.h, tm-isi.h, tm-news.h, tm-pn.h, tm-sun2.h,
14 tm-sun3.h: Remove locally duplicated code for calling functions
15 in the inferior. The only differences were in the specific trap
16 vectors used and whether or not an fpu was present. These are
17 now handled by appropriate definitions of BPT_VECTOR and
18 HAVE_68881 respectively. Other minor obvious cleanups.
20 * valops.c: Correct a minor misspelling.
22 * utils.c: Remove local BSD/USG hacks that are now in libiberty.
24 * dwarfread.c: Remove prototype for dwarfwarn. Does not work
27 Thu Oct 24 09:33:44 1991 John Gilmore (gnu at cygnus.com)
29 * stack.c (frame_command): Always print. Use new
30 frame_select_command to select a frame without printing.
32 * dwarfread.c: Use <varargs.h>, since <stdarg.h> is not portable.
34 Thu Oct 24 01:32:51 1991 Fred Fish (fnf at cygnus.com)
36 * dwarfread.c: New file for DWARF debugging format support.
38 * elfread.c: New file for ELF object file format support.
40 * procfs.c: New file for SVR4 /proc (process file system) support.
42 * tm-amix.h, xm-amix.h, tconfig/amix, xconfig/amix: New files for
45 * xm-svr4.h, tm-svr4.h: New files for SVR4 support.
47 * xm-m68k.h: New file for host machines with m68k cpu.
49 * Makefile.in: Add elfread.c and dwarfread.c to SFILES_MAINDIR.
50 Add elfread.o and dwarfread.o to OBS.
52 * symfile.h: Add "elf" to list of supported formats in comment.
54 * c-exp.y, defs.h, symtab.h, valprint.c: Add three new builtin
55 types to gdb, builtin_type_long_double, builtin_type_complex, and
56 builtin_type_double_complex. Add and use new TARGET_SHORT_BIT,
57 TARGET_INT_BIT, TARGET_LONG_BIT, TARGET_FLOAT_BIT,
58 TARGET_DOUBLE_BIT, TARGET_LONG_DOUBLE_BIT, TARGET_COMPLEX_BIT, and
59 TARGET_DOUBLE_COMPLEX_BIT, as the sizes in bits of the indicated
60 types on the target machine (ala the existing TARGET_LONG_LONG_BIT).
62 * infrun.c: When using SVR4 /proc interface instead of ptrace(),
63 call proc_set_exec_trap() to setup child to stop at first instruction.
65 * inftarg.c: When using SVR4 /proc interface, call proc_wait()
68 * m68k-tdep.c: Add new routines supply_gregset(), fill_gregset(),
69 supply_fpregset(), and fill_fpregset(), which are machine
70 dependent support routines for SVR4 /proc interface.
72 * utils.c: Add warning_setup() and warning(). Warning() behaves
73 the same as error() except that it returns normally rather than
74 jumping back to command level. Modules that don't want to call
75 warning() for some reason, but want to produce their own warnings,
76 can call warning_setup() to ensure compatibility with the way
77 warning() and error() deal with the terminal.
79 * symtab.c: Make internal errors produce more useful messages.
81 * tm-68k.h: Move code that is duplicated in almost every single
82 m68k based machine's configuration files to this common file.
83 Duplications in the configuration files still need to be removed
86 * infrun.c (child_create_inferior): System V versions must call
87 setpgrp() with no arguments, to comply with prototyping typically
90 * munch: Add support for SVR4 style nm output.
92 * dbxread.c, mipsread.c symmisc.c, symtab.c: Remove the object
93 file specific fields from the partial symbol table structure and
94 replace them with a pointer to private data for each different
95 flavor of object file reader to initialize appropriately.
97 Wed Oct 23 09:38:20 1991 John Gilmore (gnu at cygnus.com)
99 * xconfig/sun[34]os4: Add note about strstr botch on sunos4.0.3c
102 * mipsread.c (fixup_undef_type): New function. If a struct /
103 union / enum is defined in a header file but nowhere else used,
104 (by typedefing, pointer referencing or declaration) the mipsread code
105 builds the complete tree for the structure but leaves its code as
106 TYPE_CODE_UNDEF as it doesn't know what kind of aggregate it is.
107 Guess its type based on the details of the members.
109 Tue Oct 22 18:04:32 1991 Stu Grossman (grossman at cygnus.com)
111 * infrun.c (wait_for_inferior): Check return value from
114 Mon Oct 21 17:47:03 1991 Stu Grossman (grossman at cygnus.com)
116 * infrun.c (wait_for_inferior): fix stepi/nexti that was broken
117 by my last edit to this routine.
119 Mon Oct 21 14:27:43 1991 John Gilmore (gnu at cygnus.com)
121 * tm-sun3.h (FIX_CALL_DUMMY): problem with cross debugging.
122 FIX_CALL_DUMMY does unaligned accesses and/or forgets to byte swap
123 the values before putting them into the dummy code. (From Peter
126 Mon Oct 21 10:04:39 1991 Steve Chamberlain (steve at rtl.cygnus.com)
128 * configure.in: added ebmon target.

134 * Makefile.in: Roll VERSION to 4.2.
135 * README, TODO, WHATS.NEW: Update.
137 * core.c (core_open): Improve error message for bad file.
138 Pass .reg virtual memory address to fetch_core_registers to help
139 it find the registers in the core-file header.
140 * coredep.c (fetch_core_registers): Take new argument, use it,
141 and pass it to register_addr to locate the block of registers.
142 * xm-mips.h: Update KERNEL_U_ADDR for new scheme. Cleanup a bit.
144 * dbxread.c (read_dbx_symtab, process_one_symbol): Handle
145 Sequent N_FN_SEQ like everybody else's N_FN.
147 * main.c: Circumvent SCO cc bug with #if !!defined(USG).
148 * tm-i386v.h: #endif guck.
149 * xconfig/i386*: Remove -Dgetpagesize()=4096 kludge.
150 * xconfig/i386sco: Add HAVE_STRSTR to avoid ANSI bdeath.
151 * xconfig/tahoe: Add REGEX, which seems to be missing.
153 * coredep.c: Add <sys/types.h> for SCOnix.
154 * dbxread.c (read_dbx_symntab): Avoid coredump on malformed file.
155 * printcmd.c (print_formatted): Flush output before disassembly.
157 Tue Oct 15 20:12:32 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
159 * doc/refcard.tex (sec "Working Files"): consistent metavars and
160 other improvements, due to comments by François Pinard
161 (pinard@iro.umontreal.ca)
163 * doc/gdb.texinfo (appendix "Installing GDB"): changes in
164 configure, and improvenets related to Pinard's refcard comments
166 Tue Oct 15 08:45:12 1991 John Gilmore (gnu at cygnus.com)
168 Changes from Fred Fish:
169 * tm-68k.h (FPI_REGNUM): Add.

183 * i387-tdep.c (double_to_i387): Fix typo for double_to_ieee_extended.
184 * utils.c (_initialize_utils): If !ISATTY, don't paginate.
185 * configure.in, tconfig/decstation, xconfig/decstation: Rename
186 dec3100 to decstation.
188 Mon Oct 14 13:37:50 1991 Roland H. Pesch (pesch at cygnus.com)
190 * doc/gdb.texinfo: Catch up to changes recorded here in ChangeLog
191 (nodes Continuing and Stepping; Memory; Targets) clarifications
194 Fri Oct 11 23:27:06 1991 John Gilmore (gnu at cygnus.com)
196 * tm-{irix3,mips,nindy960,pn,symmetry,vx960}.h: Move
197 REGISTER_U_ADDR to corresponding xm- file. Sugg. by Peter Schauer.
199 * symmisc.c (print_partial_symtabs): Add printpsyms debug cmd.

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

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

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

329 * nindy-tdep.c (nindy_frame_chain_valid): Use lookup_misc_func.
330 (Reported by Mark Peek <mark@imagen.com>.)
332 * solib.c (solib_map_sections): Relocate all sections, even
333 though only the text section's size is tracked. Mark ld_text
334 for eventual elimination as we generalize to N sections.
336 * infrun.c (wait_for_inferior): Don't check if the PC is in a
337 call_dummy if we were stopped by a random signal that is being
338 passed to the program. This produced wierd results when calling
339 functions in the inferior and signals (e.g. SIGALRM) were in use.
341 Tue Sep 24 18:05:30 1991 John Gilmore (gnu at cygnus.com)
343 * infrun.c (IN_SIGTRAMP): Not parenthesized properly.
344 Bugfix from Paul Eggert <eggert@twinsun.com>.
345 * tm-ultra3.h (IN_SIGTRAMP): Ditto.
346 * valprint.c (print_floating): Print 9 digits for IEEE floats.
349 Mon Sep 23 15:50:07 1991 John Gilmore (gnu at cygnus.com)
351 * Makefile.in: Roll VERSION to 4.1.1.

355 Fri Sep 20 16:10:52 1991 John Gilmore (gnu at cygnus.com)
359 * Makefile.in (VERSION): Set to 4.1.
360 * language.c (set_language_command): Print useful help message,
361 and restore the language string after giving help.
362 * valprint.c (typedef_print): Print typedef in C or M2.
363 * symtab.c (list_symbols): Use it.
364 * main.c (main): Avoid any output before (gdb) prompt when -q.
365 * language.c (set_language_command): Handle errors by restoring
366 the language string to its current state (fix from A. Beers).
367 * doc/gdbint.texinfo: Roll in information from README. Rearrange
368 "how to install" and "how to print the doc" stuff so it drops
370 * configure.in: Rename rtpc CPU to romp to match config.sub.
371 * README, WHATS.NEW, TODO: Update for gdb-4.1.
373 Fri Sep 20 17:39:14 1991 Roland H. Pesch (pesch at cygnus.com)
375 * doc/gdb.texinfo: Updates from ChangeLog. set/show write,
376 autoloading shared libs, copyright etc on GDB startup, clean up $_
377 and $__ index refs, set/show listsize and related updates to list
378 cmd. New host/target configs.
380 Fri Sep 20 15:46:00 1991 Roland H. Pesch (pesch at cygnus.com)
382 * doc/Makefile: generate aux version-no file doc/gdbVN.m4
383 from main Makefile.in version definition
384 doc/gdb.texinfo: use version recorded in doc/gdbVN.m4 for current
386 Makefile.in (setup-to-dist): generate doc/gdbVN.m4
388 * doc/gdb.texinfo: merge new language-switching and lang-specific
391 Fri Sep 20 15:00:57 1991 Per Bothner (bothner at cygnus.com)
393 * mcheck.c: Add __ONEFILE kludge to allow compilation by non-ANSI
394 compilers (which may lack stddef.h).
396 Fri Sep 20 13:29:42 1991 John Gilmore (gnu at cygnus.com)
398 * dbxread.c (read_dbx_symtab, process_one_symbol): N_FN and
399 N_WARNING are the same except for the N_EXT bit, so just use their
400 values alone, rather than OR-ing them with N_EXT.
402 Fri Sep 20 12:27:55 1991 Stu Grossman (grossman at cygnus.com)
404 * mipsread.c (parse_lines): Deal with negative extended line
407 * c-exp.y, m2-exp.y: #define yyerrflag and yynerrs to avoid
408 global symbol conflicts.
410 Fri Sep 20 02:28:15 1991 John Gilmore (gnu at cygnus.com)
412 * .gdbinit: Move 'set complaints' to top, so it runs even in
413 case we aren't debugging GDB.
414 * language.c (_initialize_language): Fix type check and range
415 check documentation strings.
416 * utils.c (!HAVE_VPRINTF): Define vfprintf as a function, so
417 language.c can use it. (Though language.c should really not be
418 handling warnings/errors the way it does, FIXME.)
419 * symtab.c (lookup_primitive_type): const lint.
421 Bugfix from Peter Schauer:
422 * source.c (lines_to_list): Make signed, to avoid comparison
423 going unsigned and complaining that -3 is too high for 21 lines.
424 * stack.c (lines_to_list): Ditto.
426 Thu Sep 19 23:33:41 1991 John Gilmore (gnu at cygnus.com)
428 * Makefile.in (HFILES): Add minimon.h.
429 (VERSION): Roll version number to 4.0.95.
430 (gdb.tar.Z, make-proto-gdb.dir, setup-to-dist, gdb-XXX.tar.Z):
431 New rules for building distributions. Normal distribution
432 is built by doing `make -f Makefile.in gdb.tar.Z' in the directory
433 one level up from here; it calls make-proto-gdb.dir to build a
434 directory `proto-gdb' which is an image of the release. The old
435 `gdb.tar.Z' rule still works too.
436 * config.sub, configure: Roll in latest from ..
438 Thu Sep 19 17:41:24 1991 Roland H. Pesch (pesch at cygnus.com)
440 * doc/gdbint.texinfo: Reorder contents; reorganize new-host,
441 new-target, and new-config chapters; fix minor typos; come closer
442 to usual GNU markup conventions for @file @samp @code @var.
444 Thu Sep 19 17:04:12 1991 Per Bothner (bothner at cygnus.com)
446 Patches from Peter Schauer <pes@regent.e-technik.tu-muenchen.de>:
447 * mipsread.c (parse_partial_symbols): Enter the name of all
448 structs/unions... into the psymtab so we can access them if the
449 symtab is not read in.
450 * mips-tdep.c: Remove some unneeded #includes.
451 * xconfig/dec3100: Add HAVE_STRSTR.
453 Thu Sep 19 15:14:23 1991 John Gilmore (gnu at cygnus.com)
455 * Makefile.in: Circumvent Sun Make bug on *-exp.tab.o.
456 * c-exp.y, m2-exp.y: Lint.

458 * valprint.c (val_print_fields): Check for stub type.
459 * mipsread.c (_initialize_mipsread): Avoid using
460 builtin_type_void at initialize time.

463 Wed Sep 18 15:55:51 1991 John Gilmore (gnu at cygnus.com)
465 Merge multiple-language support, and partial Modula-2 support,
466 from Andrew Beers <beers@cs.buffalo.edu>.
468 * i387-tdep.c: New file, consolidates most 80387 support,
469 and eliminates host dependency on double<->extended conversions.
470 * i386-xdep.c, symm-xdep.c: Remove most 387 support.
471 * xconfig/i386{sco,v,v-g,v32,v32-g}: Now need i387-tdep.o.
473 * symfile.c (allocate_symtab): New fn, consolidates the work
474 of allocating and initializing a new struct symtab. Set the
475 language of the symtab based on its filename extension.
476 * symfile.h: Declare it.
477 * mipsread.c (new_symtab): Use it. Minor formatting changes.
478 * dbxread.c (end_symtab): Use it.
480 * mipsread.c (parse_symbol, case stParam and stProc): Add #if 0'd
481 code for saving types of parameters with each function definition.
482 * dbxread.c (define_symbol, function and parameter cases): Ditto.
483 (read_dbx_symtab, case N_DEFD): Ignore.
484 (read_enum_type): Recognize FALSE/TRUE enum as Modula-2 BOOLEAN.
485 (read_range_type): Rename MAX_OF_TYPE to MAX_OF_C_TYPE, etc.
486 #if 0 out its uses, though, since they set a dead value.

562 Tue Sep 17 08:37:41 1991 John Gilmore (gnu at cygint.cygnus.com)
564 Add Andrew Beers' changes for Modula-2 support. His ChangeLog
565 entries are enclosed herein. Not all of these changes
566 have been merged into the master GDB sources -- check the
567 ChangeLog above here for the merge log.
569 Mon Jun 3 17:05:45 EDT 1991
571 m2-exp.y Created. Tested outside of GDB for a few days. Proper
572 operators were added, C specific operators and tokens
573 removed. yylex() revamped to some extent. Still things
574 missing from the grammar, such as sets.
575 Tested for two weeks in GDB v3.5.
577 Tue Jun 11 17:23:48 EDT 1991
579 m2-exp.y Added boolean constants TRUE and FALSE to the grammar
580 so they are built-in. Sort of a hack.
582 Fri Jun 14 12:53:51 EDT 1991
584 m2-exp.y Added range checking for numeric constants. Any numeric
585 constant is assumed to be of builtin type INTEGER unless:
586 (1) it is octal or hexadecimal, in which case it is a
587 CARDINAL; (2) it is too big to fit into an INTEGER, in
588 which case it is a CARDINAL.
589 eval.c Added simple range checking for +, -, and * on integers.
590 Doesn't work very well for *, since 6 * 1,000,000,000 =
591 1,705,032,704, which fails the simple test of result >=
592 first_operand, no matter in what order the operands are.
594 Tue Jun 18 14:11:30 EDT 1991
596 Broke the parser into parts, one containing the C grammar and the other
597 containing code to be shared by all of the grammars.
599 The following files no longer exist:
604 The following files were added:
606 c-exp.y (The C grammar)
607 m2-exp.y (The Modula-2 grammar)
608 parser-code.c (Code that is shared by the above grammar)
612 Makefile.dist Changed to reflect the above dependencies. NOTE: It is
613 now necessary to use the Bison compiler compiler, since it
614 will generate function/variable prefixes other than yy.
616 Tue Jun 18 16:47:49 EDT 1991
618 symtab.[ch] Added the external variable working_lang, than holds the
619 value of the current working language.
620 Added the ennumerated type language_mode, with the values
621 language_auto and language_manual, the former meaning that
622 GDB sets working_lang as needed, and the latter meaning
623 that the value of working_lang is totally under user
625 symtab.[ch] Added the Modula-2 pervasive types INTEGER, CARDINAL,
626 REAL, BOOLEAN and CHAR. Also added the type codes
627 TYPE_CODE_BOOL and TYPE_CODE_CHAR.
628 utils.c Added set_language_command and show_language_command to
629 implement the GDB support commands "set language" and
631 expression.h A number of identifiers were added to the type exp_opcode
632 to facilitate Modula-2 builtin functions, integer
633 division, and array indexing.
635 Wed Jun 19 13:25:58 EDT 1991
637 language.h Added the macro STRICT_TYPE, which evaluates to non-zero
638 if the language specified by working_lang requires the use
639 of strict typing of expressions. Eventually, even this
640 will be able to be changed by the user.
641 Added the macro RANGE_CHECK, which evaluates to non-zero
642 if the language specified by working_lang requires the
643 checking of a value against the domain of its type.
644 Eventually, even this will be able to be changed by the
646 language.[ch] Predicates involving types (simple_type, ordered_type,
647 same_type, integral_type, numeric_type, character_type,
648 boolean_type, float_type) are added. These predicates are
649 based on the current value of working_lang, and are handy
652 Wed Jun 19 15:39:34 EDT 1991
654 eval.c Added the function type_array_rank which computes the rank
656 valarith.c Added the funtion value_bool, which when given a integer
657 value.h value (ie. struct value *) as an argument, it returns a
658 boolean value (ie. struct value *) true if that integer
659 is non-zero, and a boolean value false otherwise.
660 valprint.c Added cases for TYPE_CODE_BOOL, so Modula-2 BOOLEAN values
661 will print out properly.
663 Wed Jun 19 16:36:34 EDT 1991
665 valops.c Added the function value_capitalize, which returns it
666 value.h argument capitalized if its argument is a lowercase
667 letter, or the argument unchanged if its argument is not a
669 valarith.c Added the function range_check_p, which returns non-zero
670 value.h if its value argument is between the integral bounds upper
672 Added the function range_check_enum_p, which makes sure
673 that its value argument is a valid member of the domain of
675 Added the function range_check_range_p, which makes sure
676 its value argument lies between the upper and lower bounds
677 of its type argument, which must be a ranged type.
678 Added the function check_array_index, which range and type
679 checks an index of an array.
680 Added the function value_multi_subscript, which computes
681 array[idx1,idx2...idxN], given a value array and an array
682 of values representing indicies.
683 values.c Changed value_from_long to work with TYPE_CODE_CHAR and
684 unpack_long to work with TYPE_CODE_BOOL and
687 Wed Jun 19 18:04:08 EDT 1991
689 symtab.c Stored pervasive types in a structure and make
690 lookup_pervasive_type() a lookup function that was based
691 on working_lang. If lookup_pervasive_type() returned
692 non-zero, then that value was returned (a fix, since
693 before it simply wouldn't return the pervasive type.)
694 language.h Added the macro CAST_IS_CONVERSION, which evaluates to
695 non-zero if the language specified by working_lang means
696 "conversion" when it says "cast".
697 valops.c Added the function value_real_cast(), which performs a
698 value.h *cast*, not a *conversion*, which is what value_cast()
699 does when it can. In particular,
700 value_cast(<float_type>,4) = 4.0, while
701 value_real_cast(<float_type>,4) = some mess.
702 eval.c Modula-2 builtin functions implemented: ABS, CAP, CHR,
703 parser-code.c FLOAT, HIGH, MAX, MIN, ODD, ORD, TRUNC, and VAL.
704 expression.h Added macros MAX_OF_TYPE and MIN_OF_TYPE to work with MAX
705 and MIN on integral types. *NOTE*: These are currently
706 hardcoded to work only if there are 8 bits per storage
708 eval.c Made logical functions call value_bool to return a
709 properly typed boolean value, based on working_lang.
711 Thu Jun 20 11:55:27 EDT 1991
713 valprint.c Types now print out in a Modula-2 fashion. This works for
714 the cases when the type is printed out step-by-step, that
715 is, it doesn't work when the name of a structured type
716 (which includes the keyword "struct", etc.) is simply
718 FIXME: Perhaps this is bad. Parts of it seem to kludgey,
719 since type specifications in C and Modula-2 are very
720 different. The C printing of a type is very recursive,
721 whereas in Modula-2 it is generally very simple. C has
722 type prefixes and suffixes, which have no real analogue in
723 Modula-2. Maybe type_print() should call a language
724 specific type printer. This is also advantageous if we
725 compile GDB to exclude some of the languages. We'll just
726 leave those functions out.
728 Thu Jun 20 16:57:10 EDT 1991
730 dbxread.c When reading the complete symbol table in (via
731 psymtab_to_symtab()), the number and types of function
732 arguments are added to a function type. define_symbol()
733 calls add_param_to_type() to accomplish this.
734 Assumption: when we come across a function definition
735 (N_FUN symbol with an 'f' or 'F' in the name), its
736 arguments will appear before another function definition.
737 When a function is found, a pointer to its type is placed
738 in the global in_function_type. Changes that
739 add_param_to_type() makes are to this global.
740 valprint.c The type of a function now includes (for Modula-2) the
741 types of its parameters.
742 eval.c Type checking and a check for the proper number of
743 arguments is now done for function calls. Not sure of the
744 impact this has on C++ member function yet.
746 Thu Jun 20 19:58:48 EDT 1991
748 valprint.c Rewrote the type printer. Broke it into two language
749 specific parts, adding the functions type_print_m2() and
751 An unfortunate consequence is this: if you debugging a C
752 program in Modula-2 mode (why?), info types does not work
753 well with regular expressions, since the types are printed
754 out in Modula-2 terminology, but stored in C terminology.
755 language.[ch] Added the functions new_type_last(), type_keyword(), and
756 type_sep() to aid in the printing of typedefs.
757 symtab.c Made the printing of typedefs as language independent as
758 possible through calls to new_type_last(), type_keyword(),
761 Fri Jun 21 11:50:26 EDT 1991
763 dbxread.c Check all incoming ennumerated types. If it looks like
764 Modula-2's BOOLEAN type, then change the type_code of the
765 type to TYPE_CODE_BOOL so we can process it as a boolean
767 valprint.c Replaced some of the 0x%x with calls to sprintf and
768 hexformat() in val_print().
769 language.[ch] Added the function hex_to_string(), which converts its
770 integral argument to a hexadecimal number (format is
771 language based) and returns the result as a string.
773 Mon Jun 24 12:25:07 EDT 1991
775 valprint.c Some functions call type_print_1() directly, instead of
776 value.h using type_print(), so they can specify where (column) to
777 print things. Since type_print() takes care of language
778 dependence, that needs to be called first. Added a
779 parameter depth to type_print() (so it is now like
780 type_print_1). Changed type_print to type_print_at, and
781 made type_print a macro that passes a depth argument of
783 symmisc.c Changed all calls to type_print_1 to calls to
785 Makefile.dist Made it possible to build GDB for a specific set of
786 depend languages. Do this by passing a definition for the macro
787 LANGS to make. LANGS should be a string containing a
788 space-separated list of language names (ie. LANGS="c m2").
789 The default is to build all languages. Note that grammar
790 files must follow the naming convention of <lang>-exp.y.
791 gdb.lang This holds the current value of the LANGS macro. It is
792 examined every time make is called, and is updated if
794 eval.c Added #ifdef _LANG_<lang> to these files.
795 expread.c Still need to add them to dbxread.c and coffread.c.
803 Mon Jun 24 16:33:11 EDT 1991
805 language.[ch] Added the functions hexformat_pre() and
806 hex_to_string_pre(), which take a prefix argument to
807 include in the format string. Thus, hexformat_pre("08") will
808 return "0x08x" (if the working language is language_c).
809 Made hexformat() and hex_to_string() calls to the above
810 with "" as the prefix argument.
812 am29k-pinsn.c, arm-pinsn.c, breakpoint.c, convex-tdep.c, exec.c, core.c,
813 dbxread.c, i386-pinsn.c, i386-stub.c, i386-xdep.c, i960-pinsn.c,
814 infcmd.c, inflow.c, m68k-pinsn.c, m68k-stub.c, m88k-pinsn.c,
815 mips-pinsn.c, mips-tdep.c, ns32k-pinsn.c, printcmd.c, pyr-pinsn.c,
816 pyr-tdep.c, pyr-xdep.c, remote-vx.c, remote.c, solib.c, source.c,
817 stack.c, sun386-xdep.c, symfile.c, symm-xdep.c, symmisc.c, tahoe-pinsn.c,
818 valprint.c, vax-pinsn.c
820 Changed all occurences of 0x%[0-9]*l*x in printf format strings to
821 calls to hexformat() and hex_to_string(). Format strings without
822 the leading "0x" were ignored.
824 depend Updated to take the above into account.
827 Tue Jun 25 15:27:18 EDT 1991
829 symtab.h Added the types range_mode_t, range_check_t, type_mode_t,
830 and type_check_t to keep track of the current state of
831 range and type checking.
832 main.c Added the variables range_mode, range_check, type_mode,
833 and type_check to record the current state of range and
834 type checking. Added initialization code to main().
835 language.h Changed the macros STRICT_TYPE and RANGE_CHECK to examine
839 Tue Jun 25 17:57:08 EDT 1991
841 dbxread.c process_one_symbol() updates the variable (enum language)
842 source_lang based on the extension of the filename
843 contained in the N_SO sybmol that started this symtab.
844 When end_symtab() is called, the value of source_lang is
845 put into the language field.
846 stack.c select_frame() sets working_lang (and possibly type_check
847 and range_check) to the language field of the symtab
848 associated with the frame that is selected if working_mode
849 is language_auto. If working_mode is language_manual, a
850 warning is printed and working_lang is not set.
851 language.c Added the function set_type_range(), which sets the value of
852 type_check and range_check (if their modes call for
853 automatic setting) based on the current value of
854 working_lang. A non-zero argument will cause the current
855 settings to be output.
858 Wed Jun 26 14:51:40 EDT 1991
860 eval.c Added range checks on assignment.
861 m2-exp.y Added the grammar for sets to the language. Currently,
862 these do not do anything except print an error message.
864 Wed Jun 26 17:01:04 EDT 1991
866 m2-exp.y Added the ability for parse_number() to parse negative
867 numbers. A global flag is set upon encountering a unary
868 minus. This was done to make, for example, 1 parse as a
869 CARDINAL, and not as an integer, per Wirth's examples in
870 Programming in Modula-2 ed.4.
871 valprint.c Added support for "set radix 2" by then setting
872 output_format to 't'.
873 eval.c Implemented range checking on subrange types. Added calls
874 to range_check_range_p for BINOP_ASSIGN and BINOP_VAL.
875 Implemented MIN and MAX for ennumerated types. The
876 minimum value of an ennumerated type is defined by Wirth
877 as the first identifier, and the maximum as the last.
878 m2-exp.y Made octal numbers ending with "B" be characters and those
879 ending with "C" be numbers, per Wirth's book. (p. 34)
881 Thu Jun 27 14:11:52 EDT 1991
883 stack.c select_frame() now only sets working_lang, it does not
884 notify the user. If working_mode is language_manual, then
885 a warning is issued once.
886 main.c At the end of each call to execute_command(), working_lang
887 is checked against the local static (enum language)
888 current. If they differ and working_mode is
889 language_auto, the new settings of language, type and
890 range checking are printed out.
891 stack.c Modified frame_info() to include the language of the
892 current frame in the output of "info frame".
893 language.[ch] Added the function language_str() which returns the name
894 of the current language.
896 Fri Jun 28 15:33:14 EDT 1991
898 m2-exp.y Added the built-in procedures INC, INCL, DEC, and DECL to
899 the language. INCL and DECL currently cause an error,
900 since sets are not implemented yet. INC and DEC are
901 implemented as PREINCREMENT/PREDECREMENT with one
902 argument, and as ASSIGN_MODIFY with two arguments.
903 eval.c Added type checking to the above cases.
904 value.h Added not_lval_constant to the lval_type ennumerated type.
905 not_lval_constant means that the value is a constant
906 value; that is 3 or 'a' or TRUE, not as in a constant
907 identifier. This is used to help coerce numbers such as 3
908 to either signed or unsigned numbers.
909 valops.c Added the function value_coerce_constants() which coerces
910 constant integers as following: if one is a constant and
911 the other is not, the constant's type is set to the type
912 of the other argument. If both are constants and one is
913 signed, the other is converted to a signed constant.
915 Sat Jun 29 17:26:29 EDT 1991
917 valarith.c Added a better range checker. It now checks range
918 (successfully) on integral operations [+-] (signed and
919 unsigned) for any C sized type. Still does not work well
921 int_in_size() returns an integer that is coerced to fit into
922 specified number of bytes.
924 Mon Jul 1 13:04:14 EDT 1991
926 language.[ch] Added the function binop_result_type(), which returns the
927 builtin (struct type *) type that would be the result of a
928 binop on the two values V1 and V2.
930 Wed Jul 3 19:22:53 EDT 1991
932 source.c Extended source_info() to include the source language in
933 the output from "info source".
935 Fri Jul 5 13:48:52 EDT 1991
937 utils.c Moved the support functions for the GDB set/show commands
938 dealing with language into language.c.
939 language.c Added the function language_info(), which displays info
940 about the current working language, type and range check
941 settings. Called via the GDB command "info language".
942 Added an initialization routine _initialize_language(),
943 that sets defaults for the language, type and range
944 variables and sets up the new GDB commands.
945 main.c Language setup moved to language.c.
948 Mon Jul 8 10:10:22 EDT 1991
950 valarith.c Debugged the range checker for arithmetic. Still does not
951 work for multiplication very well.
953 Mon Jul 8 12:40:37 EDT 1991
955 language.[ch] Added the function value_true() which returns non-zero if
956 its argument represents a boolean true value.
957 breakpoint.c Changed breakpoint_cond_eval() to call value_true() to
958 check the truth of an expression.
960 Thu Jul 11 12:51:34 EDT 1991
962 language.[ch] Added the predicate structured_type(), which returns
963 non-zero if the argument is a structured type.
964 Added the predicate pointer_type(), which returns non-zero
965 if the argument is a pointer type.
966 eval.c Added the ability to do addition and substraction on
967 pointers and integers. This case simply bypasses the
970 Thu Jul 11 14:41:42 EDT 1991
973 Added the symbol N_DEFD (0x4a) which is a definition
974 module dependency that is used by the GNU Modula-2
975 compiler and the linker. It is not important to GDB,
976 except that [dbx|coff|mips]read.c should ignore these
979 Fri Jul 12 16:07:00 EDT 1991
981 valprint.c Changed the TYPE_LENGTH(type) >= 0 to TYPE_LENGTH(type) >
982 0 in val_print(). Also added statements to the else part
983 to coerce type (argument to val_print) to a pointer type
984 if it is an "array of unspecified length".
985 valops.c Added the function value_m2_string(), which returns a
986 (value) value which is a constant string, whose type is
987 (ARRAY [0..n] OF CHAR). The length field of the type
988 structure is set to zero, so it will be interpreted as an
989 "array of unspecified length".
990 stack.c Moved the language/frame mismatch check to
991 main.c:execute_command().
992 main.c The working language is recorded each time
993 execute_command() is executed. If working lang has
994 changed during its execution, then the new
995 language/type/range info is printed out for the user. If
996 the working language does not match the language of the
997 frame, a warning is issued.
999 Sat Jul 13 16:16:39 EDT 1991
1001 eval.c Moved all the type-checking stuff for operators to
1002 language.[ch] language.c. This is so we can keep language-specific
1003 stuff (like for what type operators are defined) in
1005 language.[ch] Added the function binop_type_check(), which checks to see
1006 if its two (value) arguments are type-compatible with its
1007 opcode argument. The opcode should represent an operation
1008 involving an operator. Also added the macro function
1009 unop_type_check, which calls binop_type_check with a
1010 NULL second argument.
1011 expprint.c Added Modula-2 operators to the op_print_tab, so info
1012 expression.h break works correctly. Also added "op_string", which
1013 returns the string corresponding to the (enum exp_opcode)
1014 opcode that is its argument.
1017 Sat Jul 13 18:26:18 EDT 1991
1019 coffread.c Added code to record the type of function arguments with
1020 each paricular function. Code is very similar to that
1022 dbxread.c Moved add_param_to_type() to symtab.c
1023 symtab.[ch] Added function add_param_to_type() from dbxread.c
1025 *** NOTE: The above additions have not been tested.
1027 Mon Jul 15 12:50:47 EDT 1991
1029 langauge.[ch] Added the functions type_error and range_error, which work
1030 like error() except if the type/range mode is set to
1031 *_mode_warn, then they do not do a return_to_top_level(),
1032 but merely print a warning.
1033 Also changed [set|show]_[type|range]_command() to support
1034 the new "warn" feature.
1036 Thu Jul 18 17:50:54 EDT 1991
1038 mipsread.c Added code to record the type of function arguments with
1039 each particular function. Code is very similar to that
1042 *** NOTE: The above additions have not been tested.
1044 Fri Jul 19 11:19:10 EDT 1991
1046 defs.h Added macros MAX_OF_SIZE, MIN_OF_SIZE, UMAX_OF_SIZE, and
1047 UMIN_OF_SIZE, which when given a size of a numeric type,
1048 return the maximum and minimum value it can hold. UMAX...
1049 and UMIN... return the result for unsigned types.
1050 symtab.h Added the macros MAX_OF_TYPE and MIN_OF_TYPE to operate on
1051 struct types. They call above macros.
1052 dbxread.c Renamed the MAX and MIN_OF_TYPE macros to ..._OF_CTYPE to
1053 avoid a name conlict with the above.
1054 c-exp.y Added range checking on numeric constants in
1055 parse_number() for completeness.
1056 valarith.c Made binop_user_defined_p() and unop_user_defined_p()
1057 return 0 if working_lang is not language_c.
1059 Thu Aug 8 14:17:22 EDT 1991
1063 breakpoint.c Documentation strings of some commands changed to
1064 eliminate the references to the C language where
1067 Tue Aug 13 15:48:03 EDT 1991
1069 m2-exp.y Added qualified identifiers to the grammar. The semantics
1070 are slightly different from those of the GDB operator ::
1072 m2-exp.y Added a rule to each grammar of the form: start ::= exp |
1073 type_exp, where type_exp is any valid type expression.
1075 eval.c Added the opcode OP_TYPE, and an error case in eval.c.
1076 printcmd.c Modified ptype_command() so it actually parses the input
1077 (necessary for type expressions with scope qualifiers).
1078 Added the function ptype_eval() which expects an
1079 expression composed of one OP_TYPE element.
1080 *.[ch] Replaced all occurences of parse_c_expression with
1082 *.[ch] Replaced all occurences of parse_c_1 with parse_exp_1
1084 [End of ChangeLog entries from Andrew Beers for Modula-2 support.]
1086 Mon Sep 16 17:19:46 1991 John Gilmore (gnu at cygnus.com)
1088 Small fixes from Peter Schauer:
1090 * infrun.c (child_attach): Lint.
1091 * solib.c (find_solib): Handle shared libs version 2.
1093 Small fixes from David Wood:
1095 * xm-ultra3.h (SYS_SIGLIST_MISSING): Typo.
1099 * remote-vx.c: Move <stdio.h> to top, for FILE. Fix from
1100 John S <basrai%kanga.dnet@c3po.sm-alc.af.mil>.
1102 * utils.c (wrap_here): Avoid wrap action of fputs_filtered if
1103 chars_per_line is at maximum (user typed `set width 0'). Fix
1104 from Andreas Schwab <schwab@ls5.informatik.uni-dortmund.de>.
1106 Tue Sep 17 17:31:04 1991 Stu Grossman (grossman at cygnus.com)
1108 * coredep.c: include ptrace.h where necessary.
1109 * mipsread.c(parse_lines): fix unsigned char problem that was
1110 messing up line numbers on SGI's and possibly other MIPS based
1112 * infrun.c (child_create_inferior): use better test to check
1113 return val from setpgrp().
1114 * tm-irix3.h, xm-irix3.h, tconfig/irix3, xconfig/irix3: add these
1115 for sgi/irix support.
1117 Wed Sep 18 04:33:31 1991 Per Bothner (bothner at cygnus.com)
1119 * mipsread.c (parse_symbol): Put non-static procedures
1120 in the global block.
1122 Fri Sep 13 00:14:52 1991 John Gilmore (gnu at cygnus.com)
1124 Patch together `text_start' and `text_end' for 29K port.
1126 * exec.c (exec_command): If NEED_TEXT_START_END, define the
1127 variables and set them based on the exec file.
1128 * am29k-tdep.c: declare text_start.
1129 * valops.c (call_function_by_hand): declare text_end.
1131 * inferior.h: Eliminate CANNOT_EXECUTE_STACK in favor of
1132 defining CALL_DUMMY_LOCATION as BEFORE_TEXT_END. This is
1133 because machines that do this will also have to know to
1134 set NEED_TEXT_START_END. Besides, it was a redundant way to
1136 * tm-29k.h, tm-convex.h, tm-np1.h: Eliminate
1137 CANNOT_EXECUTE_STACK, define CALL_DUMMY_LOCATION and
1138 NEED_TEXT_START_END.
1140 Thu Sep 12 00:22:24 1991 John Gilmore (gnu at cygint.cygnus.com)
1142 AMD 29000 changes from David Wood <wood@david.ultra.nyu.edu>:
1144 * Makefile.in (CLIBS): Put XM_CLIBS and TM_CLIBS at end.
1145 Pass MUNCH_DEFINE to munch whenever we run it.
1146 * am29k-pinsn.c (print_insn): Handle NOP specially. Avoid %#x
1147 format string; use 0x%x instead.
1148 * am29k-tdep.c: Use DUMMY_SAVE_GREGS and RETURN_REGNUM.
1149 * ultra-xdep.c, xm-ultra.h: New files for Ultracomputer host system.
1150 * xm-rtbsd.h: New host support for RT/PC running BSD Unix.
1151 * inflow.c: Handle `short' process group IDs.
1152 * infptrace.c (fetch_register): Support CANNOT_FETCH_REGISTER,
1153 and check for ptrace errors.
1154 * coffread.c (SDB_REG_TO_REGNUM): Define if not already.
1155 (coff_symfile_init): Initialize text_bfd_scnum.
1156 (read_coff_symtab): Use it to find the text [and absolute?] sections.
1157 * ../config.sub: Add vendor nyu and os "sym[1-9]*".
1158 * configure.in: Add hosts rtpc-*-* and a29k-*-*.
1159 Merge target arm case with other "easy" cases. Add target
1160 cases a29k-*-none (rehack of am29k), a29k-*-kern (remote to
1161 Ultracomputer kernel), and a29k-*-sym1 (ultracomputer OS's user
1163 * minimon.h, remote-adapt.c, remote-mm.c: Add.
1164 * munch: Cope with RT/PC putting fns in data segment.
1165 Restore ability to override `nm' by specifying MUNCH_NM.
1166 * xconfig/rtbsd, xconfig/ultra3: New host systems.
1167 * tconfig/a29k: Rename from tconfig/am29k. Add remote-mm
1168 and remote-adapt. Remove encapsulated coff #define's (the
1169 support should go in BFD, and gdb shouldn't know or care).
1170 * tconfig/a29k-kern: Same, but for remote kernel debugging.
1171 * tconfig/ultra3: For debugging user processes on Ultra3/Sym1.
1172 * tm-29k.h: Update BADMAG (though it should go away).
1173 Allow the register definitions to be overridden in another
1174 tm-file. Fix SR_REGNUM. Add a mess of _REGNUM's. Separate
1175 RETURN_REGNUM from GR96_REGNUM and DUMMY_SAVE_GREGS from
1176 DUMMY_SAVE_GR96, for handling kernel calling conventions
1177 that use GR64+ rather than GR96+.
1178 * tm-ultra3.h: New file, for use on Ultra3 Unix as well as for
1179 remote debugging of Ultra3 kernel. Includes tm-29k.h and
1180 overrides various things.
1182 * remote-mm.c (mm_attach, mm_wait): Handle attach like
1183 child_attach does, making a clean stop in the newly attached
1185 * remote-eb.c: Lint.
1187 * coffread.c: Make coffread independent of any particular
1188 variant of COFF. Avoid #include-ing any particular one except
1189 internalcoff.h. BFD now passes key values for symbol reading
1190 as part of its coff_data structure (LINESZ, SYMESZ, AUXESZ,
1191 and the symbol masks and shifts); use them.
1192 Remove obsolete end_of_text_addr.
1194 * exec.c: Remove unused include files.
1196 Wed Sep 11 19:38:44 1991 John Gilmore (gnu at cygint.cygnus.com)
1198 * Makefile.in (documentation targets): Pass $(M4).
1199 Bugfix from eggert@twinsun.com (Paul Eggert).
1201 * stack.c (down_silently_command): Check for stack existence.
1203 Tue Sep 10 23:08:29 1991 John Gilmore (gnu at cygint.cygnus.com)
1205 * Makefile.in (VERSION): Update to 4.0.3.
1207 Tue Sep 10 09:19:29 1991 John Gilmore (gnu at cygint.cygnus.com)
1209 * core.c (core_file_command): Print frame at coredump with
1210 its level number, by calling print_stack_frame.
1211 * frame.h: Add selected_frame_level, print_stack_frame.
1212 * frame.h, stack.c: Remove print_sel_frame, print_selected_frame.
1213 * convex-tdep.c, convex-xdep.c, infcmd.c, inflow.c, infrun.c:
1214 Change print_sel_frame and print_selected_frame callers to
1217 * dbxread.c (read_ofile_symtab): Avoid empty else clause.
1218 * symfile.c (free_named_symtabs): Ditto.
1219 * main.c (main): wrap_here needs an arg.
1220 * solib.c (find_solib): Avoid memory access if _DYNAMIC is zero.
1221 (solib_add): Avoid noise.
1222 (solib_create_inferior_hook): Lint.
1223 (sharedlibrary_command): Move dont_repeat to here.
1224 * utils.c (error): Call wrap_here to force buffered output.
1226 Small patches from Peter Schauer:
1228 * coffread.c (start_symtab): Free any existing line_vector before
1230 (read_coff_symtab): Ditto for type_vector.
1232 * source.c (lines_to_list): New variable, replacing function.
1233 (all uses): Use as variable.
1234 (_initialize_source): Add 'set listsize' and 'show listsize'.
1235 * utils.c (lines_to_list): Remove function.
1236 * stack.c (print_frame_info): Use as variable.
1237 * defs.h (lines_to_list): Remove declaration.
1239 Mon Sep 9 13:45:57 1991 John Gilmore (gnu at cygint.cygnus.com)
1241 * breakpoint.c (insert_breakpoints): Restore warning about
1242 the program might be running in another process, but only for
1243 systems with this brain death (#ifdef ONE_PROCESS_WRITETEXT).
1244 * xm-hp300bsd.h, xm-mips.h, xm-vax.h: Define it.
1246 * utils.c (error): if error_pre_print is set, print the string
1248 * main.c (main, print_gnu_advertisement, print_gdb_version):
1249 Reformat legalese so it always prints, but acts as an "I'm here"
1250 message while symbols are being read. If any errors occur,
1251 print a few newlines to set off the message and start it at the
1252 left margin. Remove mention of "help" command, and don't yak
1253 about symbol reading.
1254 (catch_errors): Error string is now printed first in case of
1256 * command.c (undef_cmd_error, lookup_cmd): On undefined command,
1257 suggest the "help" command.
1259 * Makefile.in (VERSION): Set to 4.0.2.
1261 Thu Sep 5 23:49:48 1991 John Gilmore (gnu at cygint.cygnus.com)
1263 * .gdbinit: Remove useless "rr" command. Set complaints
1264 to 1 for people debugging gdb.
1266 * breakpoint.c, remote-vx.c: Reword strings printed by
1267 catch_errors callers.
1269 Wed Sep 4 11:07:50 1991 John Gilmore (gnu at cygint.cygnus.com)
1271 * WHATS.NEW: "history write -> history save". Doc "write on/off".
1272 (Fix from kenc@viewlogic.com.)
1274 Fix some infrastructure to be able to cope with host and target
1275 machines with different sized basic types (ints, ptrs, etc).
1276 (Idea from pierre@la.tce.com (Pierre Willard).)
1278 * values.c (value_from_longest): Rename from value_from_long.
1279 Handle pointer types as well as integers, so that targets with
1280 different pointer sizes from the host can be accomodated.
1281 * breakpoint.c, convex-tdep.c, eval.c, expprint.c, printcmd.c,
1282 valarith.c, valops.c, valprint.c, value.h, values.c: Rename
1283 uses of value_from_long to value_from_longest.
1284 * eval.c, findvar.c, printcmd.c, valarith.c, valops.c: Pass
1285 the correct pointer type to value_from_long{est}.
1287 * doc/gdb.texinfo ($_, $__): Describe types of these variables.
1289 * remote-vx.c: Remove obsolete code for calling functions via
1290 vxworks kludge interface (it referenced value_from_long).
1292 * valops.c (value_string): Find malloc with lookup_misc_func, not
1295 Tue Sep 3 18:37:46 1991 John Gilmore (gnu at cygint.cygnus.com)
1297 Make writing to files work properly. (Fixes to BFD are also needed.)
1299 * core.c (core_open): Open file ourselves, read or r/w, depending on
1300 write_files. Use bfd_fdopenr.
1301 * gdbcore.h (write_files): New variable.
1302 * exec.c (write_files): Define variable, add set&show for it.
1303 (exec_file_command): Use write_files to open for read or r/write.
1305 Make shared library reading happen automatically. These changes
1306 are mostly from Peter Schauer <pes@regent.e-technik.tu-muenchen.de>.
1308 * inferior.h (stop_soon_quietly): Add to exported variables.
1309 * infrun.c (child_create_inferior): call solib hook, if defined.
1310 (child_attach): call solib hook, if defined.
1311 * solib.c: Include inferior.h. Add from_tty to so_list as kludge.
1312 (find_solib): Use lookup_misc_func rather than hand-rolled.
1313 (symbol_add_stub): New stub for catch_errors.
1314 (solib_add): Avoid output if !from_tty. Catch errors rather
1315 than just calling symbol_file_add and bombing.
1316 (solib_create_inferior_hook): Interface with the target process
1317 to let it read and alloc shared libs, then figure out what it did.
1319 * core.c (validate_files): Fix typo, soften warning.
1320 (Fix from Hiroto Kagotani <kagotani@cs.titech.ac.jp>.)
1322 * utils.c (fputs_demangled): Avoid duplicate printing if
1323 demangling is off. (Fix from J.T. Conklin <jtc@cayenne.com>.)
1325 * infrun.c (proceed): Cast -1 to (CORE_ADDR) before comparing.
1326 (Fix from pierre@la.tce.com (Pierre Willard).)
1328 * main.c (catch_errors): Change argument to a char * from an int,
1329 since a char * can point to a struct full of glop, but an int
1330 is not guaranteed to be able to hold a pointer.
1331 * breakpoint.c (breakpoint_cond_eval, bpstat_stop_status,
1332 breakpoint_re_set_one, breakpoint_re_set): Adapt.
1333 * core.c (core_open, solib_add_stub): Adapt.
1334 * remote-vx.c (symbol_stub, add_symbol_stub, callers): Adapt.
1336 Wed Aug 28 18:18:05 1991 John Gilmore (gnu at cygint.cygnus.com)
1338 * Makefile.in: Update VERSION to 4.0.1. Evade GNU Make bug
1339 by adding .NOEXPORT target.
1341 Fri Aug 23 17:14:25 1991 John Gilmore (gnu at cygint.cygnus.com)
1345 * Makefile.in (VERSION): Roll to 4.0.
1346 (gdb.tar.Z): Make refcard.ps as well, for shipment.
1348 Fri Aug 23 14:07:09 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1350 * doc/gdb.texinfo: minor rewordings, crossref to ptype from print,
1353 * doc/Makefile, Makefile.in: generate "gdb-all.texi" rather than
1356 * doc/rdl-apps.texi: renamed from rdl-apps.texinfo
1358 * Makefile.in, doc/Makefile, doc/.Sanitize, doc/gdb.texinfo:
1359 reflect above name change
1361 * WHATS.NEW: correct pointer to refcard.
1363 * doc/gdb.texinfo: update New Features, Installing
1365 * doc/gdbint.texinfo: add short description of configure +template
1367 Fri Aug 23 11:46:08 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1369 * doc/gdb.texinfo: update, fix bugs in "Installing" appendix
1371 Fri Aug 23 01:02:00 1991 John Gilmore (gnu at cygint.cygnus.com)
1373 * Makefile.in: Add config.sub, make doc/rdl-apps.texinfo for
1374 tar file, add dependencies for referenced doc files.
1376 Thu Aug 22 22:17:06 1991 Stu Grossman (grossman at cygint.cygnus.com)
1378 * coffread.c, symfile.c, stack.c: saberized.
1380 Thu Aug 22 16:20:27 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1382 * doc/refcard.tex: permuted Essential Commands sec
1384 * doc/gdb.texinfo: new C++ chapter; revised installation appendix;
1386 set/show symbol-reloading
1387 default set complaints 0
1389 RET-repeat disabled after prompted long displays
1390 processID (attach) interpretation of 2nd GDB cmdline arg
1392 Thu Aug 22 14:05:47 1991 Stu Grossman (grossman at cygint.cygnus.com)
1394 * expread.y, coffread.c, dbxread.c, target.c, mem-break.c,
1395 cplus-dem.c, values.c, valprint.c, symfile.c, remote.c,
1396 breakpoint.c, main.c: lint.
1398 Thu Aug 22 02:02:26 1991 John Gilmore (gnu at cygint.cygnus.com)
1400 Install new configuration scheme for GDB and friends.
1402 * config.sub: Translate ordinary names to three-part names.
1403 * configure: Use three-part names internally.
1404 * configure.in: Translate three-part names to filenames.
1406 * README, WHATS.NEW: Update for gdb-4.0.
1407 * Makefile.in: Roll VERSION to 3.99.
1409 Wed Aug 21 18:21:09 1991 John Gilmore (gnu at cygint.cygnus.com)
1411 * infptrace.c (KERNEL_U_ADDR_BSD): Include a.out.gnu.h.
1412 * i960-tdep.c, m68k-tdep.c, sparc-tdep.c, tm-i960.h,
1413 tm-m68k.h, remote-nindy.c: Change ext_format_XXX structs
1414 to single structures rather than arrays; when passing
1415 their address, use &. This avoids trouble with bdead compilers.
1416 * mcheck.c: Don't include <stdlib.h>; just declare "void abort();"
1417 instead. This avoids portability headaches.
1418 * mips-tdep.c (mips_do_registers_info): Only print FP regs if
1420 * source.c (open_source_file): Avoid ANSI const bdeath by
1421 skipping declaration and then casting result value.
1422 * tm-hp300bsd.h: Clarify comment.
1423 * utils.c (strstr): Result is const char *; ANSI bdeath.
1424 * xm-hp300bsd.h: Define HOST_BYTE_ORDER. Redefine INT_MIN,
1425 since system include file defines it differently from "defs.h",
1426 though the two are equivalent for our purposes.
1427 * tconfig/hp300bsd: Add m68k-tdep.o.
1429 Tue Aug 20 16:01:11 1991 John Gilmore (gnu at cygint.cygnus.com)
1431 * tconfig/sun*4: Remove warnings about system assembler.
1433 Mon Aug 19 13:44:46 1991 John Gilmore (gnu at cygint.cygnus.com)
1435 * mcheck.c: Avoid warning about undeclared abort fn.
1436 * tm-sparc.h (PC_ADJUST): Avoid calling error() from this;
1437 it causes recursive calls to error() when used in cleanups.
1438 To do so requires that we make it a function, so we do.
1439 * sparc-tdep.c (sparc_pc_adjust): New implem of PC_ADJUST.
1440 * utils.c (do_cleanups): Remove the current cleanup from the
1441 chain *before* calling it, in case error() is called from it.
1442 The result won't be pretty, but won't be an infinite loop either.
1444 Mon Aug 19 00:41:04 1991 Michael Tiemann (tiemann at cygint.cygnus.com)
1446 * dbxread.c (read_struct_type): Grok anon structs for C++.
1447 (vb_name, vptr_name): Null terminate these strings.
1449 Fri Aug 16 08:31:03 1991 John Gilmore (gnu at cygint.cygnus.com)
1451 Minor bug fixes from BSD Net2 gdb:
1453 * blockframe.c (get_prev_frame_info): If FRAME_CHAIN_COMBINE
1454 returns 0, there is no previous frame.
1455 * breakpoint.c (commands_command): If !from_tty, don't call
1456 input_from_terminal_p().
1457 * dbxread.c (record_misc_function): Speed up slightly.
1458 (compare_psymbols): Ditto.
1459 * infcmd.c (do_registers_info): Take a second argument to
1460 determine whether to print float registers. "info registers"
1461 does not do so anymore. "info all-registers" does, now.
1462 * mips-tdep.c, pyr-tdep.c (xxx_do_registers_info): Take second
1464 * tm-mips.h, tm-pyr.h (DO_REGISTERS_INFO): Pass second arg.
1465 * inflow.c (initialize_inflow): Set tflags_ours correctly.
1469 * breakpoint.c (bpstat_do_actions): Use a cleanup to restore
1470 executing_breakpoint_commands if we are interrupted by error.
1471 * coffread.c (init_lineno): Avoid problem with zero-sized linetab
1472 versus malloc/free. From: john@labtam.labtam.oz.au (John Carey).
1473 * core.c (solib_add_stub, core_open): Call SOLIB_ADD inside a
1474 catch_errors() so we can setup the frame regardless of whether
1475 the shared libs work.
1476 * ieee-float.c (double_to_ieee_extended): Get exponent from
1477 right place in little-endian systems. From John Carey.
1479 Thu Aug 15 18:43:57 1991 John Gilmore (gnu at cygint.cygnus.com)
1481 * main.c: Remove unused terminating_signals and catch_termination().
1482 (long_options): Terminate with a zero element.
1483 [Bugfix from Atsuo Kawaguchi <atsuo@hark86.harl.hitachi.co.jp>.]
1484 (gdb_readline): Make call-compatible with readline.
1485 (init_signals): Improve comments re vfork vs. signal.
1487 * utils.c (prompt_for_continue): Use new gdb_readline().
1488 If we prompt for continuation, we don't let CR repeat the previous
1489 command, once we get back to a prompt. It's too easy to keep
1490 hitting CR, expecting "--more--" prompts, and have some long
1491 command start repeating on you.
1493 Tue Aug 13 16:17:56 1991 John Gilmore (gnu at cygint.cygnus.com)
1495 * blockframe.c (frameless_look_for_prologue): Speed up by
1496 calling SKIP_PROLOGUE_FRAMELESS_P if it's defined.
1497 * tm-sparc.h (SKIP_PROLOGUE, SKIP_PROLOGUE_FRAMELESS_P):
1498 Define two variants, one faster.
1499 * sparc-tdep.c (sparc_frame_chain): Use target_read_memory
1500 and return zero, rather than giving an error.
1501 (setup_arbitrary_frame): Initialize the PC in the new frame.
1502 (skip_prologue): Add a second arg saying whether we're just
1503 checking for a frameless function or not.
1505 * core.c (core_open, core_close, core_xfer_memory): Move
1506 section table pointers and bfd* into the target_ops.
1507 (core_open): Allow errors in shared lib reading, etc.
1508 (core_files_info): Describe shared library sections.
1510 * exec.c (exec_open, exec_close, exec_xfer_memory, xfer_memory,
1511 exec_files_info, set_section_command): Move section table
1512 pointers and bfd* into the target_ops.
1513 (add_to_section_table): Add BFD to section table.
1515 * target.c (target_xfer_memory, target_info): Pass target to
1516 xfer_memory and target_info functions.
1519 * gdbcore.h: Move struct section_table.
1520 * target.h: New home of struct section_table.
1522 * solib.c (solib_add): New argument is the target_ops whose
1523 section list is to be added to, if any. Reallocate the
1524 sections in that target to add any that come from shared libs.
1525 (throughout) so_sections renamed to sections.
1526 (solib_xfer_memory): Deleted.
1527 * tm-sunos.h (SOLIB_ADD): Add target argument.
1528 (SOLIB_XFER_MEMORY): Delete.
1530 * core.c, exec.c, inftarg.c, remote-eb.c, remote-nindy.c,
1531 remote-vx.c, remote.c, target.c, target.h: Remove add_syms vector
1532 from target_ops. It's the same on all targets. Add two section
1533 pointers to target_ops.
1535 * stack.c (find_relative_frame): Dump ancient algorithm for
1536 "down", just use handy "next" pointers.
1537 (frame_command): Don't error if there is no stack; let user
1540 * inflow.c (new_tty_prefork, new_tty): New prefork routine
1541 modifies static state in the parent process; new_tty itself
1542 runs in the child and modifies the child's file descriptors
1543 to match the saved static state.
1544 * infrun.c (child_create_inferior): Call new_tty_prefork,
1547 * infptrace.c (child_xfer_memory): Add ignored target arg.
1548 * remote-eb.c (eb_xfer_inferior_memory): ''
1549 * remote-nindy.c (nindy_xfer_inferior_memory): ''
1550 * remote-vx.c (vx_xfer_memory): ''
1551 * remote.c (remote_xfer_memory): ''. Rename from
1552 remote_xfer_inferior_memory.
1554 * main.c (main): Only try to attach "corefile" argument if
1555 it starts with a digit.
1557 * symfile.c (symbol_reloading): New "set/show" variable.
1558 (symbol_file_add): Shorten message about symbol reading.
1559 (add_symbol_file_command): Merge with add_syms_addr_command,
1560 since this should work on all targets now.
1561 (stop_whining): Default to zero, to shut up complaints
1562 about bad symbol tables on many systems.
1563 (free_named_symtabs): Just exit unless symbol_reloading.
1565 * xm-sun3os4.h, xm-sun4os4.h: Define BROKEN_LARGE_ALLOCA,
1566 and add comment explaining shared library screw.
1568 * source.c: #if defined => #ifdef.
1570 Thu Aug 8 12:23:19 1991 John Gilmore (gnu at cygint.cygnus.com)
1572 * doc/gdbint.texinfo: Improve doc on porting to new OS's.
1574 Tue Aug 6 17:16:15 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1576 * doc/rdl-apps.texinfo: provide default readline-appendix finder
1577 (doc/Makefile knows how to make one for local config)
1579 * Makefile.in: use doc/Makefile for doc targets
1581 * doc/Makefile: GDB documentation now has its own Makefile
1582 doc/refcard.tex: renamed from "gdbrc.tex"
1583 doc/.Sanitize: add Makefile; recognize renamed refcard.tex
1584 doc/gdbint.texinfo: add markup in "Cleanups" chapter
1587 Fri Aug 2 00:13:06 1991 John Gilmore (gnu at cygint.cygnus.com)
1589 * values.c (baseclass_addr): When reading target memory, use the
1590 length of the basetype, not the upper type. We've only malloc'd
1591 enough space for the basetype, leading to errors in free().
1593 * expprint.c (print_subexp): Print UNOP_MEMVAL of an OP_LONG that
1594 ends up as a function specially, since we know the actual type of
1595 the pointed-to address. This (somewhat) fixes display of
1596 expressions that include misc_function_vector names. Try `cond 1
1597 !strcmp("a","b")' then `i b'.
1599 * infrun.c: Move DO_DEFERRED_STORES from proceed() to resume().
1600 The child can be proceeded from inside wait_for_inferior in
1601 evaluating breakpoint conditions, and DO_DEFERRED_STORES was
1602 getting skipped in that case.
1604 * expprint.c (print_subexp): Use filtered output, since the
1605 subroutines we call use it, otherwise the output is horribly
1606 mangled, since output of wrappable stuff comes out late.
1608 * Makefile.in: Bump VERSION to 3.98.1
1610 * infrun.c (child_create_process): Use execlp to find the
1611 shell to exec our target program. This requires some fiddling
1612 with `environ' since there is no execlpe().
1614 Thu Aug 1 15:35:17 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
1616 * Makefile.in, doc/gdbrc.tex, doc/rc-* (new files):
1617 Minor rearrangement of refcard permits two new make targets--
1618 gdbrc.dvi DVI output for refcard, using CM fonts
1619 gdbrc.ps PostScript refcard, using PS fonts
1621 Wed Jul 31 16:46:21 1991 John Gilmore (gnu at cygint.cygnus.com)
1625 * TODO, Projects, WHATS.NEW, README: Update for gdb-3.98.
1626 * Makefile.in (gdb-all.texinfo): Avoid touching file if M4 dies.
1628 Wed Jul 31 16:35:58 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1630 * doc/gdb.texinfo: last changes for release.
1631 Minor typo and formatting fixes; incorporated most fixes remaining from
1632 filed mail commenting on earlier drafts.
1634 Added warnings: pipes don't work in run command;
1635 conditions are converse of assertions;
1636 step over fn without debug info goes to next fn;
1637 vars may have "wrong" values near fn entrance, exit
1639 Added example from Kingston on printing repeated nonadjacent values
1641 Added explicit mention that in Emacs gdb mode C-c and C-z are like
1642 shell mode for signals
1644 Renamed "Stepping and Continuing" to "Continuing and Stepping" so it
1645 doesn't sound so much like its parent "Stopping and Continuing"; also
1646 moved entries on continue to top of section, so they don't get lost.
1648 Improved installation directions in appendix, added manual formatting
1651 Tue Jul 30 17:26:39 1991 John Gilmore (gnu at cygint.cygnus.com)
1653 * configure.in: Remove xm.h and tm.h even if we aren't linking
1654 new ones, so "./configure sun4; ./configure none" does the right
1655 thing. Assume that alldeps.mak and depend are already built in
1656 srcdir, and avoid running "make" (particularly "make depend",
1657 which involves "gcc") from inside configure. Build Makefile
1658 directly rather than building Makefile.conf first.
1659 * configure: Regenerate with above changes.
1660 * Makefile.in: Use $(BISON) to find bison. Roll VERSION
1661 to 3.98. Revise gdb.tar.Z procedure to produce a file
1662 called gdb-$(VERSION).tar.Z but which unpacks into a
1663 directory called "gdb". Move non-source files out of
1664 $(SFILES_SUBDIR). Pretty up alldeps.mak with comments.
1665 (depend): Don't try to do "gcc expread.y".
1666 (expread.o): Update dependencies by hand.
1668 Mon Jul 29 15:21:09 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1671 Fixed a variety of small typos that prevented info from formatting
1672 cleanly; altered too-long heading for GPL Appendix, as discussed
1673 w/RMS; Changed date on cover to July 91.
1675 Fri Jul 26 13:20:02 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1678 (1) Applied some fixes due to comments from Larry Breed (easier ones
1679 through chapsec 5.2)
1680 (2) Eliminated use of @footnote---had my doubts about it anyways, and
1681 it's broken in latest texinfo
1682 (3) Introduced *some* use of [] for optional arguments, where
1683 explanation is not simpler by listing cmd w arg and cmd w/out arg
1684 separately. Still not using @deffn.
1685 (4) Dropped in GPL-2. NOTE: one of GPL-2 or texinfo is broken; a
1686 couple of headings are too long. Need patches to texinfo or revision
1689 * Partial update to README (which still needs work for this
1690 release!): (1) use of configure corrected for new script,
1691 (2) "make gdb.dvi" and "make gdb.info" mentioned.
1693 Wed Jul 24 06:44:02 1991 John Gilmore (gnu at cygint.cygnus.com)
1695 * symtab.c (lookup_symbol): Don't complain right off about
1696 no debug symbols; use the misc function vector first.
1697 (list_symbols): Use misc function vector to find symbols
1698 that don't have debug info, and print them.
1699 (find_pc_symtab): Temporarily avoid fatal() when psymtab
1700 PC range doesn't match symtab PC range, as it does on the
1701 MIPS because our symtab reading isn't perfect.
1703 * dbxread.c (dbx_symfile_read): Make warning about
1704 "no debug symbols" slightly nicer.
1706 * source.c (select_source_symtab): If "main" symbol exists,
1707 but decode_line_spec can't find line info, don't just return
1708 a zero; try other source symtabs or give an error.
1710 * mipsread.c (parse_partial_symbols): Sort the psymtabs by
1711 their low addresses first, then rip through fixing high addrs.
1713 * ns32k-opcode.h (sfsr): Bugfix from Rune Nerg}rd,
1714 <runene@ifi.uio.no>.
1715 (NS32K_SVC_IMMED_OPERANDS): Reverse the #ifndef.
1717 Tue Jul 23 18:52:43 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1719 * Minor, mostly mechanical, cleanup of doc subdir for clean
1720 makeinfo'ing and TeXing; also ensured gdb-all.texinfo (post-m4)
1721 and gdb.info (post- texinfo2 makeinfo) generated for distribution.
1723 Sun Jul 21 03:54:52 1991 John Gilmore (gnu at cygint.cygnus.com)
1725 Mostly MIPS and general symbol-reading fixups.
1727 * doc/gdbint.texinfo: Add documentation on symbol-reading
1730 * mipsread.c: Remove kludges around #include "ecoff.h".
1731 Remove redefinitions of a_magic, etc, no longer used.
1732 (parse_symbol, ): Convert "Internal:" printfs to complain()ts.
1733 Fix global overview comments to match symfile.c protocol.
1734 (mipscoff_new_init): Eliminate cur_hdr if we have one.
1735 (mipscoff_symfile_read): Eliminate unused code. Avoid
1736 sorting all the symtabs, when all we have read here is psymtabs.
1737 The symtabs are sorted as they are created anyway. Tell
1738 condense_misc_bunches whether we're mainline.
1739 (psymtab_to_symtab_1): Pass filename when recursing, to make
1740 stack trace more informative.
1741 (parse_partial_symbols): Assume cur_hdr as argument.
1742 (read_mips_symtab): Don't clobber cur_hdr, so it can be freed.
1743 Pass cur_hdr implicitly to parse_partial_symbols. Avoid checking
1744 the TYPE_NAME of char *, since that's done in symfile.c.
1745 (free_numargs, parse_symbol, add_symbol, add_block,
1746 shrink_linetable): Declare these fns void.
1747 (upgrade_type): Convert tree of if's to switch. Clean up
1748 bogus "off == 0" handling with a complaint. Avoid setting
1749 field bitpos and bitsize of array with lower and upper bounds.
1750 Check specified bitsize of elements against their actual type's
1751 bitsize, and complain if different. Complain about unknown
1753 (parse_fdr): Don't assume sizeof(char *) == sizeof (struct *).
1754 (psymtab_to_symtab_1): Print names of subsidiary files that
1755 are being read in. FIXME, we read far too many files. This code
1756 is not the problem, the problem is in parse_fdr where the psymtabs
1758 (cross_ref): Result should indicate that we used one aux entry
1759 normally, or two if we encountered a "next" entry. This used
1760 to leave the caller pointing at the wrong aux entry.
1761 (add_symbol): If overflowed cur_block, reallocate it larger,
1762 chase all pointers to it, and complain(), rather than clobber memory.
1763 (shrink_block): Use xrealloc rather than xmalloc-and-copy.
1764 (new_field): Only allocate one field initially, not two.
1765 Pull ++ out of macro argument. Simplify.
1766 (_initialize_mipsread): Avoid initialization of importd
1767 global_psymbols and static_psymbols.
1769 * symfile.c (psymtab_to_symtab): Depend on XXX_psymtab_to_symtab
1770 to properly set pst->symtab; avoid searching for it.
1771 (symfile_fns): Improve comments, add a FIXME.
1772 * dbxread.c: Update comments to reflect symfile protocol.
1773 (read_ofile_symtab, end_symtab): Return the symtab.
1774 (psymtab_to_symtab_1): Set pst->symtab.
1776 * coffread.c (coff_symfile_read): tell condense_misc_bunches
1777 whether we're mainline.
1779 * symfile.h (sym_fns): Remove unused sym_discard member.
1780 * coffread.c, mipsread.c, dbxread.c: Remove XXX_symfile_discard.
1782 * mtrace.c (mtrace): Take effect if mallwatch is set, even if
1783 the environment variable is not.
1784 * infcmd.c (finish_command): Use filtered printfs.
1785 * cplus-dem.c: Add struct tags to a few unnamed structs.
1786 * valops.c (value_coerce_array): Improve comments.
1787 * valprint.c (type_print_varspec_suffix): Print array size only
1788 if greater than zero.
1789 * m88k-tdep.c: Shift some lines left by one space, that had
1790 apparently been trashed at some point.
1791 * TODO: More things to do, a few got done.
1793 Thu Jul 18 22:46:05 1991 John Gilmore (gnu at cygint.cygnus.com)
1795 * symtab.h (LOC_EXTERNAL): Eliminate in favor of LOC_STATIC.
1796 (ldsymoff, ldsymlen, globals_offset, statics_offset): Improve
1798 * dbxread.c (read_dbx_symtab): LOC_EXTERNAL -> LOC_STATIC.
1799 * expread.y, findvar.c, symmisc.c: Ditto.
1800 * printcmd.c (address_info): Update printed forms of LOC_
1801 symbols. Elim LOC_EXTERNAL.
1802 (print_frame_args): Keep track of param stack offsets before
1803 re-looking up to find the local register param is kept in.
1805 * mipsread.c: Use <symconst.h> and <sym.h> rather than <syms.h>.
1806 Further integration of mipsread into gdb. Eliminate unused
1807 routines, duplicate declarations. Handle static symbols in
1808 psymtabs as well as external symbols. When reading symtabs,
1809 insert symbols into the correct block (global, static, or a local
1811 (read_mips_symtab, parse_partial_symbols): Don't pass useless
1813 (mipscoff_symfile_read): Don't call select_source_symtab.
1814 (parse_symbol): Use SYMBOL_VALUE_ADDRESS where appropriate,
1815 rather than SYMBOL_VALUE.
1816 (parse_external): Comment clobbering of top_stack.
1817 (parse_partial_symbols): Update comments. Allocate and parse
1818 static symbols as well as external symbols. FIXME, enum values
1819 are not handled in this pass, but should be. Inline new_psymbol.
1820 Use SYMBOL_VALUE_ADDRESS.
1821 (psymtab_to_symtab_1): Read symbols into global static block
1822 by default (until enter some function's local block context).
1823 (sort_blocks): Clean up STATIC_BLOCK as well as GLOBAL_BLOCK.
1824 (destroy_all_symtabs, new_psymbol): Eliminate, unused.
1826 * source.c (select_source_symtab): Select a source symtab
1827 from either the symtabs or, failing that, the psymtabs.
1828 (list_command): Update error message.
1829 (forward_search_command, reverse_search_command): Use getc, not
1830 fgetc, for speed. FIXME, add comment about buffers that die if
1831 overrun by long line.
1833 * values.c (unpack_field_as_long, modify_field): Avoid shifting
1834 by an entire word, which is not portable, if we have a 32-bit
1835 field. (Code in dbxread.c already turns such bitfields, if
1836 aligned, into ordinary ints, but fixing this will help for other
1837 symbol formats and for future changes.)
1838 * core.c (core_open): Handle ANSI const brain death.
1839 * utils.c (vprintf): Fix varargs typo.
1841 Sun Jul 14 00:42:53 1991 John Gilmore (gnu at cygint.cygnus.com)
1843 * findvar.c (find_var_value): Handle &function better.
1844 * TODO: Document work needed on &fn and &array.
1845 * printcmd.c (print_address_symbolic): New arg is the prefix
1846 to print if a name is printed.
1847 (print_address_demangle): Honor "set print address" now.
1848 Use new arg above to improve spacing of output.
1849 * valprint.c (val_print): When printing function pointers,
1850 print symbolic form too.
1851 * breakpoint.c (breakpoint_1): Use new print_address_symbolic.
1853 Mon Jul 8 19:02:46 1991 John Gilmore (gnu at cygint.cygnus.com)
1855 * core.c (memory_error): Reword error msg to mislead less.
1857 * mips-pinsn.c (print_insn_arg 'd'): Print $ with reg name.
1859 * mipsread.c (read_mips_symtab, read_the_mips_symtab,
1860 parse_partial_symbols): Use newer BFD internals (external_filehdr
1861 and external_aouthdr), byte-swap the fields that we care about
1862 before using them, and make the file header data local to
1863 read_the_mips_symtab rather than global.
1865 Sat Jul 6 01:34:15 1991 John Gilmore (gnu at cygint.cygnus.com)
1867 * ns32k-opcode.h (movmw, movmd): Fix opcodes. Bug fix
1868 from Rune Nerg}rd <runene@ifi.uio.no> on 5 Jul 1991.
1870 * main.c (command_line_input): Flush stdout and stderr
1871 before every call to readline. This reportedly fixes a bug
1872 that comes up in Sys V running emacs-gdb and/or xxgdb,
1873 when stdin/out are pipes or sockets.
1875 Thu Jul 4 14:47:06 1991 John Gilmore (gnu at cygint.cygnus.com)
1877 * configure.in, Makefile.in: Avoid rebuilding "depend" as much.
1878 Avoid declaring Makefile dependencies, because GNU Make stupidly
1879 tries to update it if we do.
1881 * coffread.c: Revise for minor changes to bfd internal coff
1884 * configure: If -template= is given a relative path, make it
1885 absolute before recurring in subdirectories.
1887 * configure, configure.in, Makefile.in: Install "configure" script
1888 as replacement for config.gdb.
1889 * config.gdb, Makefile.dist, Makefile.sdir: Remove
1890 * README: Update for configure, mostly. FIXME.
1892 * Add dec3100 as equivalent to littlemips. Indicate in all host &
1893 target config files that they are for the host. When the lines
1894 get copied into the Makefile, this makes it more obvious what's
1897 Mon Jun 24 23:49:07 1991 John Gilmore (gnu at cygint.cygnus.com)
1899 * sparc-opcode.h (trap opcodes): Avoid leading spaces or
1900 tabs, which end up in the disassembler output inadvertently.
1902 Wed May 29 23:01:03 1991 John Gilmore (gnu at cygint.cygnus.com)
1904 Make it compile cleanly in an ANSI GCC2 environment.
1906 * blockframe.c: <stdio.h>
1907 * cplus-dem.c: free takes a void *, ifdef __STDC__
1908 * dbxread.c (read_huge_number): avoid gcc2 bug hoisting calc of
1910 * defs.h (alloca): Avoid doing anything if alloca already def'd.
1911 * stddef.h, stdlib.h: Remove these files.
1912 * symtab.c: Avoid declaring qsort, close.
1913 * symfile.c: Avoid declaring close.
1914 * utils.c (vprintf): Declare "ap" arg as proper va_alist.
1915 * sparc-tdep.c: Avoid including lots of Sun-host-specific files.
1917 Assorted other changes.
1918 * dbxread.c: include "libaout.h", not "liba.out.h".
1919 * printcmd.c (print_frame_args): Set recurse properly for
1920 indentation of struct and array parameters.
1921 * valops.c (value_cast): Allow cast to void.
1922 * infrun.c (resume): If NO_SINGLE_STEP, call machine dependent
1923 single_step() in a target-independent fashion.
1924 * sparc-tdep.c (single_step): Don't call ptrace ourselves, just
1925 set up to be ready to continue. This makes us target independent.
1926 * infptrace.c (child_resume): Remove call to single_step; now
1927 can single step a SPARC target of any kind.
1929 Wed May 22 18:18:24 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
1931 * Makefile.dist, doc/gdb.texinfo, doc/*-m4.texinfo: split up GDB
1932 docn into separate sections---basically chapters, plus two loose
1933 pieces that can be configured to go in different places. This
1934 allows GNU m4 to preprocess the manual without coredumping.
1936 * Makefile.dist: tell TeX where to find texinfo.
1938 Mon May 20 12:15:04 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
1940 * Makefile.dist, doc/gdb.texinfo: respectively create, and use,
1941 the new target "rdl-apps.texinfo" which captures the Makefile
1942 variable that records where to find the Readline libraries.
1944 Sun May 19 05:36:59 1991 John Gilmore (gnu at cygint.cygnus.com)
1946 * tahoe-pinsn.c: #include "tahoe-opcode.h", not "opcode.h".
1947 * tm-tahoe.h (FIX_CALL_DUMMY): Ignore more parameters.
1948 * defs.h (const, volatile): Only define if not already defined.
1949 * Makefile.dist (gdb.tar.Z): Create doc subdir w/out CVS/RCS crud.
1951 * README: Update for release 3.95.
1952 * config.gdb: Don't create readline dir in subdir builds.
1953 * main.c: Include with "..." form for non-system include files,
1954 so "gcc -MM" for "make depend" works.
1955 Include readline files with "...h" rather than <readline/...h>.
1956 * mipsread.c: Include "ecoff.h" rather than "intel-coff.h".
1958 * coffread.c: Undo minor damage done by Rich Pixley. Use
1959 different internal and external representations of COFF
1960 data structures. Use new BFD routines for swapping them in and
1962 * symfile.c (free_named_symtabs): Avoid freeing file names that
1963 are null or empty. Old i960 tools seem to produce files that
1964 claim to have empty names, causing each successive file read
1965 to blow away the previous one.
1966 * sparc-xdep.c (deferred_stores): Repair minor damage by Rich.
1967 Move deferred_stores to top of file, but don't separate its
1968 #define's from its variable. Add commentary.
1969 * Makefile.dist: Fix Rich damage; undo "configure" changes in
1970 favor of keeping the (working) config.gdb. Move readline
1973 Fri May 17 12:49:56 1991 Per Bothner (via gnu at cygint.cygnus.com)
1975 * dbxread.c (read_struct_type): Try to handle g++ version 1 MI
1977 * infptrace.c (fetch_registers): no result, since now void.
1978 * tconfig/news: target depends on m68k-tdep too.
1980 Fri May 17 14:40:14 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
1982 * Makefile.dist: added readline/inc-*.texinfo to dependencies for
1985 * readline/inc-history.texinfo, readline/inc-readline.texinfo:
1986 applied various small fixes due to or inspired by RMS comments
1988 * doc/gdb.texinfo: finished using all RMS comments, save those for
1989 appendices on readline and cmd history (which are in other source
1992 Thu May 16 18:06:05 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
1994 * doc/gdb.texinfo: (1) Updated w/ref to RMS comments through
1995 chapter 9; (2) documented 'break' command's menu mode for
1996 overloaded names, in response to hgs problem report C++ p-31
1998 Wed May 15 11:02:48 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
2000 * doc/gdb.texinfo: (1) better introductory example; (2) more
2001 consistent use of @code, @samp, @file, @kbd throughout; small
2002 cleanups to first three nodes; (3) new "Contributors" node;
2003 (4) Appendix, Renamed Commands; (5) divert specialized startup
2004 instructions to "Targets" chapter for generic manuals, while
2005 leaving them up front for manuals specific to specialized
2006 environments; (6) apply fixes from RMS comments through chapter 4.
2008 * pretex.m4: modify explanatory text slightly (and redefine
2009 "regexp") to keep GNU m4 from complaining. (It still crashes
2010 later, but one step at a time...)

2022 stuff for config manual) here where it counts; updated
2023 to use new subdir structure (gdb/doc/).
2025 * Makefile: generated from above via
2029 * gdbint.texinfo: added instructions on generating gdb.info* files
2030 locally for release. These are ordinary info
2031 files, formatted from gdb.texinfo (via gdb-all.texinfo, see
2032 Makefile)---but due to use of texinfo 2, can't count on makeinfo
2033 to generate these, so we distribute them already formatted.
2035 * gdb.texinfo: included full Info node and menu crud (as generated
2036 by C-u M-x texinfo-master-menu using the texinfo-2 elisp code).
2038 * Makefile: updated "gdb.dvi" target to use M4 preprocessor;
2039 put in comments-for-future gdb.info target (one day makeinfo will

2047 set, info source, info terminal, info types, info user, set/show
2049 Also covered all recent GDB command renames for v4.

2053 * mipsread.c: Rather than keeping count of how many symtabs
2054 and psymtabs we have, for sorting purposes, count them when

2081 * remote.c: Remove decls of memory_insert_breakpoint
2082 and memory_remove_breakpoint, no longer used. (Suggestion of
2085 * Makefile.dist: use ${subdir} in paths of BFD and LIBIBERTY,
2086 to make it easier to interface to "configure"'d libraries.

2482 before returning locals or slocals.
2484 * i386-tdep.c (i386_follow_jump): Do not add data16 to pos in

2516 tm-sun3.h: Define TARGET_SUN3.
2518 * utils.c: Use CPLUS_MARKER not '$'.
2520 * cplus-dem.c: Use CPLUS_MARKER not '$'. If CPLUS_MARKER isn't
2521 defined, define it to '$'.
2523 * arm-opcode.h: New file (same contents as before; it had
2524 just been left out of the distribution for a long time).

2594 * inftarg.c (child_open), remote-vx{,.68}.c (vx_proc_open):
2595 New function to give correct error message.
2597 Thu Apr 11 17:19:41 1991 Jim Kingdon (kingdon at cygint.cygnus.com)
2599 * target.h: Add to_doc and target_preopen.
2600 target.c: Add target_preopen and target_command.
2602 (add_target): Call add_cmd and mess with targetlist->doc.
2603 core.c, exec.c, remote-eb.c, remote-nindy.c, remote-vx.c,
2604 remote-vx.68.c, inftarg.c, remote.c: Add doc field to target struct.
2605 Call target_preopen from open routine.
2607 * main.c: Rename editing_info to show_commands.

2624 Thu Apr 18 18:08:30 1991 John Gilmore (gnu at cygint.cygnus.com)
2626 * symfile.h (free_named_symtabs): Rename from free_named_symtab.
2627 * symfile.c (clear_symtab_users_once, cashier_psymtab,
2628 free_named_symtabs): Move these routines from symmisc.c.
2629 * symmisc.c (same): same.
2630 (free_symtab): Make non-static.
2631 * symtab.h (free_symtab): Declare as exported void fn now.
2632 * dbxread.c (end_symtab, end_psymtab): Change comments.
2633 (initialize_dbxread): Call dbx_new_init() in case the first
2634 command is add-symbols.
2635 * target.c (dummy_target): Permit add_syms_addr_command.
2637 Sat Apr 13 14:46:07 1991 John Gilmore (gnu at cygint.cygnus.com)
2639 Permit symbols to be superseded when new symbol files have
2640 been read in, particularly for VxWorks.
2642 * dbxread.c (read_dbx_symtab): Allow N_SOL to cleanly take us back
2643 to the main file, as well as to include files. Also, put global
2644 functions into the global psymtab, to make "i fun" work.
2645 (end_psymtab): Free named symtabs and psymtabs for a file, once a
2646 new psymtab for it has been read.
2647 * coffread.c (end_psymtab): Free named symtabs and psymtabs for
2648 a file, once a new symtab has been read for it.
2649 * mipsread.c: FIXME. We need to do the same for MIPS, but it
2650 looks harder to determine the top-level block before it's been
2651 queued to the psymtab list.
2653 * symfile.c (symbol_file_add): Use filtered printing and wrap it.
2654 If we have wiped out any old symbol tables, clean up at end of
2656 (symbol_file_command): Don't reference symfile_fns if it's zero.
2658 * symtab.h (GLOBAL_BLOCK, STATIC_BLOCK, FIRST_LOCAL_BLOCK): New
2659 defines for the blocks of a blockvector that contain global and
2660 file-static symbols and the first of the smaller scope contours.
2661 * symtab.c (lookup_symbol, find_pc_symtab, find_pc_line,
2662 decode_line_1, make_symbol_completion_list): Use the above.
2663 * coffread.c (end_symtab, patch_opaque_types): Ditto.
2664 * dbxread.c (end_symtab): Ditto.
2665 * expread.y (block): Ditto.
2666 * mipsread.c (throughout): Ditto.
2667 * symmisc.c (free_named_symtabs): Ditto.
2669 * symtab.c (list_symbols): Process the first symbol of the
2670 static psymbols list.
2671 (types_info): Restore this function from its untimely #if 0.
2672 It's not perfect, but it is better than nothing.
2673 (_initialize_symtab): Restore "info types".
2675 Thu Apr 11 05:23:19 1991 John Gilmore (gnu at cygint.cygnus.com)
2677 * m68k-stub.c: Remote stub for 680x0's, created from
2678 rem-m68k.shar (which is removed).
2679 * nindy-share/{Makefile,Onindy.c,blout.h,env.h,nindy.c,ttyflush.c}:
2680 Remove RCS log stuff now that we use CVS and it blows our diffs.
2682 Wed Apr 10 14:18:06 1991 John Gilmore (gnu at cygint.cygnus.com)
2684 * symmisc.c (free_named_symtab): Make it work, in its current
2685 kludgy fashion. Change result to indicate if we blew away bkpts.
2686 * dbxread.c (end_symtab): Accumulate result from
2687 free_named_symtab and print warning if we blew user's state.
2688 * symfile.h: free_named_symtab now returns an int.
2690 Mon Apr 8 23:57:43 1991 John Gilmore (gnu at cygint.cygnus.com)
2692 * dbxread.c (dbx_symfile_read): Initialize psymbol list if this
2693 is the first symbol read, even if not mainline.
2694 (dbx_psymtab_to_symtab): symfile might be zero, cope.
2695 * exec.c (exec_ops): Add_syms_addr is valid in our tvec.
2696 (set_section_command): New command ("section xxx yyy" -- should
2697 be renamed to "set section xxx yyy" FIXME) which sets the
2698 base address of a section of the exec file, overriding the
2699 virtual address that BFD reports.
2701 Fri Apr 5 17:14:39 1991 John Gilmore (gnu at cygint.cygnus.com)
2703 * exec.c: Add add_syms_addr_command to exec_ops, so you can
2704 load symbols at any address while examining an exec file.
2706 Thu Apr 4 10:09:35 1991 John Gilmore (gnu at cygint.cygnus.com)
2708 * tm-i386v.h (FLOAT_INFO): Don't define it, since the code
2709 for printing the float info is host-dependent, not
2710 target-dependent. FIXME.
2711 * i386-pinsn.c: Move #includes to top, remove useless ones.
2712 * i386-tdep.c: Don't bother including <.../reg.h> since we
2713 don't use it (and it doesn't exist on host systems).
2715 * ieee-float.c (ieee_extended_to_double): Convert NaN to Inf.
2716 Convert negative numbers properly.
2717 (ieee_test): Make numbers really random; fix format arg.
2719 * infcmd.c (attach_command, detach_command): Don't repeat on CR.
2720 * core.c (core_detach): Unpush core_ops, which might not be on
2721 top. We used to just pop the top, which broke things. Don't
2722 need dont_repeat() any more.
2723 (core_file_command): Psst! Don't repeat it.
2724 * remote-nindy.c (nindy_detach): Don't need dont_repeat() now.
2725 * expprint.c (print_subexp): Avoid switch fallthru on
2726 BINOP_ASSIGN_MODIFY, so we can print += and such.
2727 * frame.h: Fix typo.
2728 * inflow.c (kill_command): After killing inferior, print our
2729 current frame in the core file, if we have one.
2730 (generic_mourn_inferior): When inferior dies, either select
2731 the current frame (in the new target, e.g. core file), or
2732 set both the current and selected frames to NULL.
2734 Changes from Peter Schauer.
2736 * infptrace.c: Avoid <sys/ptrace.h> on USG.
2738 * Make all file names fit in 14 characters (sigh and damn!):
2739 mv hp300hpux-xdep.c hp300ux-xdep.c
2740 mv symmetry-xdep.c symm-xdep.c
2741 mv symmetry-tdep.c symm-tdep.c
2742 mv convex-opcode.h convx-opcode.h
2743 mv tm-vxworks960.h tm-vx960.h
2744 mv tm-vxworks68.h tm-vx68.h
2745 mv Makefile.srcdir Makefile.sdir
2746 mv gdb-int.texinfo gdbint.texinfo
2747 mv remote-sa.m68k.shar rem-m68k.shar
2748 mv remote-multi.shar rem-multi.shar
2749 * Makefile.dist, README, config.gdb, convex-pinsn.c,
2750 tconfig/symmetry, tconfig/vxworks960, tconfig/vxworks68,
2751 xconfig/hp300hpux, xconfig/symmetry: Change names to shorter
2754 * command.c (user_info_1, user_info): New command for listing
2755 the user-defined commands.
2757 Wed Apr 3 15:00:26 1991 John Gilmore (gnu at cygint.cygnus.com)
2759 * dbxread.c (really_free_pendings): Clear file_symbols
2760 and global_symbols after freeing them; otherwise, running
2761 this function twice (if it appears twice on the cleanup
2762 chain), we try to free things twice.
2764 * dbxread.c (read_dbx_symtab): Calculate end_of_text_addr
2765 based on text_addr (the address of text in core), not on addr (the
2766 offset between text in the .o file and in core). This change
2767 is from Peter Schauer.
2769 * main.c: Define ALL_CLEANUPS as a cast of zero.
2770 (return_to_top_level): Use it.
2771 (main): Do all cleanups after each command run as part
2772 of the gdb startup sequence. Also do all cleanups before
2773 entering the command loop, and every time we exit the command
2774 loop and reenter. Before, the cleanups from the startup sequence
2775 were being left undone until the first error!
2776 (command_loop): Rename do_nothing cleanup to command_loop_marker
2777 so we can see it easily when examining the cleanup chain.
2778 (init_signals): Add another do_nothing for signal handling.
2779 (quit_command): Only try to kill target if it has execution.
2780 Problems in the target stack got us into a state where
2781 inferior_pid was nonzero but none of the targets had execution.
2782 In this state you couldn't exit gdb.
2784 * dbxread.c: Two changes from Peter Schauer.
2785 (echo_command): Fflush output after an echo command.
2786 (show_history): Pass all args to cmd_show_list.
2788 * utils.c (init_malloc): Call mtrace to turn on tracing
2789 if the environment variable MALLOC_TRACE is set to a file name.
2790 * mtrace.c: Add source file which provides a log of every malloc,
2791 free, and realloc to a trace file.
2792 * mtrace.awk: Add source file which analyzes the trace file.
2793 * Makefile.dist (GNU_MALLOC, MALLOCSRC): Add mtrace.{c,o,awk}.
2794 (VERSION): Roll to 3.94.3.
2796 * breakpoint.c (breakpoint_1): Add a space to "i watch" output.
2797 (check_duplicates): Don't bother with watchpoints.
2798 (set_raw_breakpoint): Comment about danger of this routine.
2799 (watch_command): Parse and eval all args before calling
2802 * solib.c (find_solib): Avoid error in referencing memory to
2803 see if any more shared libraries have been added. This is
2804 particularly useful if the target has terminated. Bug reported
2807 Changes from Peter Schauer <pesrem@regent.e-technik.tu-muenchen.de>
2808 in bringing up 3.94.2 on the Sun-3.
2810 * Makefile.dist: Include CFLAGS in rule for cplus-dem.o.
2811 * breakpoint.c (enable_breakpoint): Check for valid watchpoint
2812 expression (in scope) before reenabling watchpoint.
2813 * signame.c (init_sigs): Add missing declaration of i, fix
2814 sys_siglist declaration.
2815 * source.c (list_command): Fixed range computation to use
2817 * stack.c (backtrace_command): Do not allow command if target has
2818 no stack, print informative error message.
2819 * target.c (target_command): Do not write into command line
2820 because this fails if the target command is used in a user defined
2821 command. [This change was enhanced by gnu to support any-
2822 unique-prefix matching on target names.]
2823 * valops.c (value_struct_elt): Avoid infinite loop on an
2824 erroneous attempt to print the member of function (try p main.p).
2826 Mon Apr 1 17:05:45 1991 John Gilmore (gnu at cygint.cygnus.com)
2828 * expread.y (name_no_typename): Avoid reduce/reduce errors
2829 caused by ambiguity in handling NAME_OR_INT and NAME_OR_UINT.
2830 Since the GDB parser really doesn't use name_no_typename in a
2831 name-only context, the parser can't tell the diff between
2832 names and numbers here. Avoid allowing a name_no_typename
2833 to be a NAME_OR_*INT to resolve the conflict.
2835 Sun Mar 31 20:12:07 1991 John Gilmore (gnu at cygint.cygnus.com)
2837 Bugfixes from Mark Fox (markf@wrs.com) (test=testField.c):
2839 * valprint.c (val_print_fields): bitfield printing didn't handle
2840 byte order. Indirect through a few more fns to cope.
2842 * values.c (modify_field): also cope with byte order.
2844 Sat Mar 23 10:02:21 1991 John Gilmore (gnu at cygint.cygnus.com)
2846 Cleanup for release 3.94.2:
2848 * Makefile.dist: Pull REMOTE_OBS. Fix saber includes for BFD
2849 include files. Roll version to 3.94.2.
2851 * coffread.c (init_stringtab): Read length into unsigned char
2852 array before swapping; don't assume 32-bit longs.
2854 * target.c (target_info): Don't bother with get_sym_file, just use
2855 the symfile global variable.
2856 * symtab.h, symfile.c (get_sym_file): Delete it.
2858 * dbxread.c (dbx_symfile_init): Don't depend on long == 4 bytes.
2859 (define_symbol): Set symbol line number to 0 if not gcc-compiled.
2860 (read_type): Replace one more error() with complain().
2862 * mipsread.c (parse_partial_symbols): Replace printf with complain.
2864 * i960-tdep.c: Fix copyright attribution.
2866 * config.gdb: Quote all backquotes in doublequotes. You can
2867 quote me on that. BSD 4.4 shell found this one.
2869 * infptrace.c (throughout): The third argument to ptrace is an
2872 * infrun.c (wait_for_inferior): When program has terminated, we
2873 have to call target_terminal_ours before we pop that target off
2874 the stack (e.g. before a call to target_kill or
2875 target_mourn_inferior). This fixes problem where a program
2876 terminates, then GDB stops for (tty output) and you have to type
2877 "fg" to the shell to resume it. FIXME: This code for what to
2878 do after termination really should be in normal_stop instead.
2880 * gdbcore.h (read_memory_check): Change declaration; it changed
2883 * terminal.h: Include <sgtty.h> before <sys/ioctl.h>, since in BSD
2884 4.4 prereleases, this avoids a bug in their sgtty compatability
2886 * remote.c: Use terminal.h rather than hand-rolling the same.
2888 * signame.c, signame.h (psignal): Arg is unsigned, not int.
2889 * utils.c (strsave, strstr): Fix arg types.
2890 * valprint.c (val_print): lint
2892 MIPS symbol table support from Per Bothner:
2894 * symfile.c (symtab_fns): Remove initializer table that needs to
2895 be hacked for each new symbol file format supported.
2896 (add_symtab_fns): New function, chains symbol table
2897 handlers into the global list.
2898 (symfile_init): Search this list.
2899 * symfile.h: Add next pointer, declare add_symtab_fns.
2900 * coffread.c (_initialize_coffread): Call add_symtab_fns.
2901 * dbxread.c (_initialize_dbxread): Call add_symtab_fns.
2903 * mipsread.c (psymtab_to_symtab_1): return void instead of (struct
2904 symbol *). Thus, we no longer need the hack to trash
2905 pst->filename. Good, since that hack confused code in symfile.c!
2907 (reorder_symtabs, destroy_all_symtabs): Removed static
2908 all_symtabs, which was used to qsort symtabs in reorder_symtabs.
2909 Instead, the latter now uses a temporary array (stack-allocated
2910 from an obstack, and then freed).
2912 (parse_symbol): Added a hack to fix up BLOCK_{START,END} if they
2913 haven't been set in the outermost stBlock of a procedure. This was
2914 a problem with f77 binaries on Ultrix 4.?.
2916 (new_symtab, new_symbol, new_type): Continue changing code to use
2917 obstacks more and otherwise conform to dbxread internal style.
2918 Made the free_code of symtabs be free_linetable (as in dbxread)
2919 instead of free_contents. This implies memory leaks when reading
2920 a new symbol table, until the conversion is finished. Did change
2921 (struct symbol) and (struct type) to be allocated on the
2922 symbol_obstack. Blocks and blockvectors are among the things
2925 * mipsread.c (parse_partial_symbols, parse_fdr): It hasn't been
2926 tested much, but it solved one problem (reported by Meissner), and
2927 cleans up some other things. The problem happened when an
2928 included file contains actual code (functions) and not just
2929 definitions. The mips coff is a little inconvenient there, since
2930 it may cause a procedure to be mapped to the wrong psymtab.
2932 * mips-tdep.c (heuristic_proc_desc): Minor cleanup.
2933 * mips-xdep.c (fetch_core_registers): Minor cleanup. FIXME,
2934 this will need work for the new core paradigm.
2936 Opcode patches from the net:
2938 * mips-opcode.h: fix incorrect disassembly of the mfc1, cfc1, and
2939 ctc1 instructions. Also, the cvt.d.w and cvt.s.w instructions were
2940 missing altogether - they are added here. From Bruce Bauman.
2941 * mips-opcode.h: The low mask for C0 instructions was too small.
2942 From Garrett Lau. I modified the fix to check the entire 32-bit
2945 * ns32k-opcode.h: Fix opcodes for deiw and deid. From Bruce
2948 Thu Mar 21 12:56:46 1991 John Gilmore (gnu at cygint.cygnus.com)
2950 Roll in changes from Per Bothner (Tue, 25 Sep 90 11:11:04):
2952 * dbxread.c (read_type): Pointer subtraction (value_sub in
2953 valarith.c) sometimes failed because the types of the
2954 pointers being subtracted were not identical.
2955 These differed because dbxread.c was allocating pointer types
2956 using dbx_alloc_type+smash_to_pointer_type instead of
2957 lookup_pointer_type. I failed to find a justification for the
2958 former, so I changed it to use the latter. Similarly, I
2959 replaced smash_to_function_type by lookup_function_type,
2960 and smash_to_reference_type by lookup_reference_type.
2962 * mipsread.c (parse_symbol, upgrade_type, parse_procedure,
2963 _initialize_mipsread): corresponding changes.
2965 * symtab.c (smash_to_{pointer,reference,function}_type): eliminate.
2967 * source.c (mod_path): Do tilde_expand on each component of the path,
2968 rather than on the (list of) paths as a whole.
2969 (print_source_lines): Set first_line_listed in addition to
2970 current_source_symtab and current_source_line. If the source was
2971 not findable, after a "dir" command to fix the problem,
2972 a "list" would get the wrong lines.
2974 While I was there... (gnu):
2976 * dbxread.c (read_type): Change error to complaint.
2978 Thu Mar 21 12:56:46 1991 John Gilmore (gnu at cygint.cygnus.com)
2980 First attempt at detailed understanding of symbol table memory alloc.
2982 * dbxread.c (dbx_symfile_read): Free our string table if we
2983 aren't the mainline. Free the "info" struct since we're done with
2985 (init_psymbol_list): Free any previously allocated psymbol lists.
2986 (): FIXME: Should realloc-down the psymbol lists when done reading
2987 the main symbol file?
2989 * symmisc.c (free_symtab): Free fullname field too.
2991 * xm-hp300hpux.h (USG): #undef then #define so Makefile can -D.
2992 (REGISTER_ADDR): Make result type unsigned int.
2994 * xconfig/{i386*,hp300hpux,altosgas,altos}: All config files that
2995 define REGEX must also define REGEX1 (its dependency).
2997 Tue Mar 19 21:28:57 1991 John Gilmore (gnu at cygint.cygnus.com)
2999 * tconfig/i960: No longer works, points you at vxworks960 or

3004 * Makefile.dist: Remove all trace of xgdb.
3006 * breakpoint.c (breakpoint_1): Pass demangle arg to
3007 print_address_symbolic.
3008 (clear_breakpoints): Remove unused function.

3010 (breakpoint_re_set): Use catch_errors to do them all anyway.
3012 * gdb-int.texinfo (Host versus Target): Add section on what is
3013 a "host" feature versus what is a "target" feature.
3015 * infcmd.c (path_command, path_info): Handle the PATH variable
3016 (object search path) as conveniently as the source search path.
3017 * environ.c (set_in_environ): Set some vars in GDB's environment,
3018 in addition to the child's. PATH, G960BASE, G960BIN for starters.
3019 * source.c (mod_path): New function, from guts of
3020 directory_command, modifies a path. Used by path_command.
3021 (directory_command): Call it.
3022 * defs.h (strsave): Declare.

3025 (printchar): Use it.
3026 (strsave): Provide this handy helper routine.
3027 (set_width_command): Rename set_screen_width_command.
3028 (_initialize_utils): "set screen-width" => "set width";
3029 "set screen-height" => "set height"; add sevenbit-strings.
3031 * infcmd.c (do_registers_info): Print floating point registers
3032 in raw hex as well as float format, regardless of whether it is
3033 a "virtual" convertible register.
3034 * tm-sparc.h (PRINT_REGISTER_HOOK): Print every pair of float
3035 regs as a double, just in case it's being used that way.
3036 * values.c (unpack_long): Comment on array/function coercion.
3037 (unpack_double): Argument is in target byte order now. For
3038 integer arguments, just call unpack_long and float the result.
3039 * m68k-tdep.c: include defs.h for "const" handling.
3040 * remote-nindy.c: Use ieee-float stuff.
3041 (nindy_fetch_registers): Unpack double regs to host double, then
3043 (nindy_store_registers): Pack extendeds to host double, flip
3044 around by misusing unpack_double, send as target double.
3046 * tm-vxworks68.h (FRAME_CHAIN): Handle current frame pointer of
3047 zero, as when stopped at the first instruction of a process.
3049 * blockframe.c: Fix filename in comment (param.h => tm.h).
3050 * sparc-tdep.c (skip_prologue): More explicit nudging comments.
3051 * tm-68k.h: Fix typos.
3053 Fri Mar 15 01:09:34 1991 John Gilmore (gnu at cygint.cygnus.com)
3055 Changes from a bringup on the DEC Vax under Ultrix 4.0.
3057 * coredep.c (fetch_core_registers): Pass end-address of register
3058 section to register_addr as expected. Don't call supply_register
3059 if we'd just pass it garbage.
3061 * dbxread.c (read_dbx_symtab): Skip N_NSYMS on Ultrix.
3063 * exec.c (xfer_memory): Use boolean xfer_fn result, not int.
3065 * target.c (push_target, target_info): Cast enums to int for < or

3069 even if we can't print it.
3071 * xm-vax.h (MISSING_VPRINTF): No longer missing in Ultrix V4.0.
3073 Sat Mar 9 10:08:20 1991 John Gilmore (gnu at cygint.cygnus.com)
3075 Clean up IEEE floating point support.
3077 * ieee-float.h: New file.

3082 sun2os4,sun3,sun3os3,sun3os4}: Eliminate use of m68k-xdep.o.
3083 * tm-i960.h, tm-68k.h (REGISTER_CONVERT_TO_VIRTUAL,
3084 REGISTER_CONVERT_TO_RAW): Use ieee_extended_to_double and
3085 double_to_ieee_extended.
3086 * i960-tdep.c: Define ext_format_i960.
3087 * m68k-tdep.c: Define ext_format_68881.
3088 * sparc-tdep.c: Define ext_format_sparc, though unused.
3089 * Makefile.dist (HFILES): Add ieee-float.h.
3090 * inftarg.c: #include "ieee-float.h" for the REGISTER_CONVERT

3096 * nindy-share/nindy.c (coffstrip): Routine to run bfd_strip.
3097 * Makefile.dist: Remove references to nindy-share/coffstrip.c.
3098 * tconfig/nindy960: Remove reference to coffstrip.o.
3100 * Makefile.dist: Roll version number to 3.94.1 (not yet final).

3105 * dbxread.c: Remove static symfile_bfd.
3106 * infcmd.c (do_registers_info): Add PRINT_REGISTER_HOOK, though
3108 * inftarg.c (child_detach): Pop the child_ops vector if the
3109 detach is successful.
3110 * remote-nindy.c (nindy_create_inferior): Don't push a new
3111 nindy_ops since nindy uses the same one for execution and memory
3113 * core.c (core_ops): Use child_attach and child_create_inferior
3114 rather than default attach and create_inferior functions.
3116 Handle floating point registers in core files.
3118 * sparc-xdep.c (fetch_core_registers): Rewrite for float support.
3119 * sun3-xdep.c (fetch_core_registers): Rewrite for float support.
3120 This version untested since BFD doesn't yet support sun3 core
3122 * hp300hpux-xdep.c: Rewrite fetch_core_registers to new calling
3123 conventions. Fix comments and style. This version has not
3124 been compiled yet, since we have no HP inhouse.
3125 * core.c (get_core_registers): Look for two sections, ".reg"
3126 and ".reg2", and pass both to fetch_core_registers sequentially.
3128 Revise directory path yet again.
3130 * source.c (forget_cached_source_info): Not static any more.
3131 (init_source_path): New default source path is "$cdir:$cwd".
3132 (dir_command): Handle variable arguments ($cdir, $cwd).
3133 (source_info): Print "Compilation directory" rather than
3134 "Originally compiled in" to remind people of $cdir.
3135 (openp): If the path contains $cwd, use current directory.
3136 (open_source_file): If compilation directory is known, replace
3137 first $cdir in path with the compilation directory.
3138 (print_source_lines): Even if we can't print the lines, set the
3139 current symtab and line for future commands like "info source" or
3140 "breakpoint". Also, error message now contains the file name,
3141 line number, and file access error message.
3142 (_initialize_source): Fix help text to describe changes.
3143 * main.c (cd_command): Forget cached source info when we chdir.
3144 * utils.c (strstr): Add simple implementation.

3148 * coffread.c (read_one_sym, init_linetable, init_stringtab):
3149 Byte-swap COFF symbol tables if necessary when reading them in.
3150 Use complain() to replace error message in one spot. Needs
3151 corresponding change in bfd/coff-code.h to make some symbol
3152 swapping routines non-static.
3154 Mon Mar 4 00:53:40 1991 John Gilmore (gnu at cygint.cygnus.com)
3156 Merge changes from Eirik Fuller, for UTek.

3164 declarations of errno.
3166 * remote-eb.c: Define B19200 and B38400 as EXTA and EXTB.
3168 * remote-vx.c: Include <sys/time.h> for UTek; Sun gets it via
3169 <rpc/rpc.h> and <rpc/types.h>.
3171 Sat Mar 2 15:47:55 1991 John Gilmore (gnu at cygint.cygnus.com)
3173 * i960-tdep.c (examine_prologue): Add new argument limit,
3174 which stops the scan at the end of the prologue, or at the PC.
3175 This fixes a problem where it walks down into the code for the
3176 user's statements if that code looks like function prologues.
3177 Mark Fox and I have been bouncing this code back and forth, making
3178 small changes to it. Callers changed to match.
3180 Tue Feb 26 01:47:07 1991 Cygnus John Gilmore (cygnus at yuba)
3182 Cleanup for gdb-3.94 release final:
3184 * Makefile.dist: Remove remote-vx.c, remote-nindy.c, and all
3185 the .c files from vx-share and nindy-share, from the various
3186 macros, since they are not found via ALLDEPFILES.
3187 (SFILES): Add tm-i960.h.
3188 (alldeps.mak rule): Break out ALLDEPFILES_MAINDIR and
3189 ALLDEPFILES_SUBDIR. List all the nindy and vxworks subdir files
3191 (TAGFILES_MAINDIR): Change ALLDEPFILES to ALLDEPFILES_MAINDIR.
3192 (gdb.tar.Z): Use ALLDEPFILES_SUBDIR as well as SFILES_SUBDIR.

3196 * am29k-tdep.c: Add contribution line.
3197 (examine_prologue): Cache information about function prologues in
3198 the misc-function-vector to avoid lots of references over the
3199 serial line while examining instructions.
3201 * core.c (core_close): New function made from cleanup_core.
3203 * core.c, exec.c, inftarg.c, remote-eb.c, remote-nindy.c,
3204 remote-vx.c, remote.c, target.c, target.h,
3205 Update target_ops vector to add attach, close, and load entries.
3206 Use add_syms_addr_command, not add_file_addr_command, for
3207 add_file. Break out close routine from existing code.
3209 * dbxread.c (really_free_pendings): Don't free pending_blocks;
3210 they are in an obstack.
3211 (read_dbx_symtab): Relocate end_of_text_addr in the psymtab.
3213 (define_symbol): Add symbol type parameter; change callers;
3214 pass type parameter to DBX_PARM_SYMBOL_CLASS macro to allow
3215 it to influence the symbol class on the i960.
3216 (define_symbol): Swap LOC_CONST's into target byte order.
3218 * exec.c (exec_close): New function.
3219 (exec_file_command): Call it.
3221 * findvar.c (read_relative_register_raw_bytes): Doc byte order,
3222 Fix byte order of frame pointer.
3223 (read_var_value): Result of 0 if var's value can't be found,
3224 e.g. missing FRAME_ARGS_ADDRESS. Byte-swap LOC_CONST and
3225 LOC_LABEL values to target order. Add LOC_LOCAL_ARG.
3226 (locate_var_value): Use read_var_value and use its lazy address
3227 as the location of the var's value. Lint.
3229 * i960-pinsn.c (next_insn): Add routine from vxgdb for scanning
3232 * i960-tdep.c (arg_address, i960_frame_find_saved_regs): Remove
3233 obsolete Intel versions in favor of vxgdb versions.
3234 (check_host, byteswap, byteswap_val, reorder_val): Eliminate
3235 code dealing with byte order of values, which Intel did in host byte
3236 order rather than gdb-4's target byte order.
3237 (i960_frame_chain_valid): Move to nindy-tdep.c.
3238 (examine_prologue, skip_prologue, frame_find_saved_regs,
3239 frame_args_address, leafproc_return, saved_pc_after_call,
3240 pop_frame): Add vxgdb versions from Mark Fox.
3241 (examine_prologue, frame_struct_result_address): Add code
3242 to deal with the saved value of G13 (struct return address
3244 (frame_args_address): Modify Mark's version to prefer the
3245 saved value over the current value in the topmost frame.
3246 Cache result in the frame info to avoid performance hair in
3248 (print_fault): Add gdb960 code for printing faults.
3249 (_initialize_i960): Actually call check_host.
3251 * ieee-float.c (ieee_extended_to_double, ieee_double_to_extended):
3252 add stub routines. FIXME, these currently just return zero!
3254 * infcmd.c (program_info): Use PRINT_RANDOM_SIGNAL.
3255 (attach_command): Call target_attach, not target_open, now.
3257 * infrun.c (normal_stop): Make global, not static, for vx_attach.
3258 (child_attach): Rename from child_open.
3259 (wait_for_inferior): Use PRINT_RANDOM_SIGNAL. If stop_pc is zero,
3260 don't confuse it with a zero step_resume_break_address.
3262 * inftarg.c (child_detach): Eliminate inferior_pid test.
3263 (child_files_info): Clean up message a bit.
3264 (child_ops): Use child_attach, not child_open, to attach.
3266 * mem-break.c: #ifdef out the whole file if BREAKPOINT is not
3267 set (e.g. on VxWorks or NINDY). Move read_memory_nobpt from
3268 findvar.c to here, since it depends on the contents of the
3269 shadow_contents of breakpoints, but keep if #if 0 since it is
3272 * nindy-tdep.c: New file, contains nindy_frame_chain_valid, moved
3275 * printcmd.c (address_info): Handle LOC_LOCAL_ARG. Lint.
3276 (ptype_command, display_command): Eliminate have_inferior_p and
3277 have_core_file_p in favor of target_has_stack or
3278 target_has_execution.
3279 (print_frame_args): Handle LOC_LOCAL_ARG. Eliminate duplicate
3280 code for actually finding the values of arguments, though we still
3281 keep track of the maximum stack offset for use in printing unnamed
3282 arguments. Handle missing FRAME_ARGS_ADDRESS.
3284 * remote-nindy.c (i960_print_fault): Move to i960-tdep.c.
3285 (struct nindy_regs): Define registers passed to/from nindy.
3286 (nindy_fetch_registers, nindy_store-registers): Translate between
3287 nindy and GDB formats for the registers.
3288 (dcache_init): Statically allocate the cache, since it was being
3289 allocated by a malloc that was never freed anyway.
3290 (nindy_create_inferior): Error, not core dump, if no exec file.
3291 (nindy_before_main_loop): Use target_load, not target_add_file.
3293 * remote-vx.c (net_load): Specify large timeout for load
3294 requests. Allow user to break out with INTERRUPT.
3295 (net_break): Remove useless code, clean up. Change callers.
3296 (parse-args, skip_white_space, find_white_space): Clean up arg
3297 parsing to cope with quoted strings.
3298 (net_wait, net_quit): Never call error, just return status.
3299 (vx_read_register, vx_write_register): Cleanup status checking.
3300 #ifdef the code based on which CPU we are using (960 or 68k),
3301 FIXME, this should be completely general but it isn't yet.
3302 (vx_xfer_memory, vx_resume): Cleanup status checking.
3303 (vx_run_files_info): Improve message.
3304 (vx_load_command): Renamed from vx_add_file_command. Allow load
3306 (net_ptrace): Remove unused routine.
3307 (vx_wait): Adopt code from vxgdb960 to cope with broken
3308 connections to target machine and prompt to disconnect. Remove
3309 debug printouts. Map some EVENT_'s to SIGnals.
3310 (add_symbol_stub, vx_open): Print names of object files we found,
3311 and "ok" if we read their symbols OK. Clarify output in general.
3312 (vx_attach, vx_detach, vx_kill): Add these commands.
3313 (vx_convert_from_virtual, vx_convert_to_virtual): Simplify.
3314 (vx_run_ops): Turn off all_mem, to avoid spurious msg in the
3315 "info files" output, and create_inferior, since we already have
3318 * stack.c (frame_info): Replace Frame_unknown with 0.
3319 (print_frame_arg_vars): Handle LOC_LOCAL_ARG.
3320 (return_command): Pop until the PC matches as well as the FP,
3321 so it works even if the FP is shared with another function,
3322 as in "frameless" or "leaf" procedures.
3324 * symfile.c (load_command): renamed from add_file_target_command.
3325 (add_syms_addr_command): renamed from add_file_addr_command.
3326 (add_syms_command): Stub to call target_add_syms.
3327 (_initialize_symfile): Change command names and descriptions,
3328 add-file => add-syms, and load from alias to its own command.
3330 * target.c (kill_or_be_killed, maybe_kill_then_attach,
3331 maybe_kill_then_create_inferior): Default for attempts to start
3332 a process, if one is already running, is to ask about killing
3333 it and retry if yes.
3334 (upstack_create_inferior): #if-0 it, strata obsolete it.
3335 (push_target, unpush_target, pop_target): to_close() a target
3336 before unstacking it.
3337 (target_info): Renamed from target_files_info.
3338 (_initialize_targets): Rename "i files" as "i target", accessible
3341 * target.h: Improve comments about the target_ vectored routines.
3343 * tm-i960.h: Remove NINDY-specific stuff to tm-nindy960.h.
3344 Convert commenting style to standard GNU style.

3346 (SKIP_PROLOGUE): No longer a no-op.
3347 (SAVED_PC_AFTER_CALL): Now handles leaf procedures.
3348 (*_REGNUM): Sort register numbers.
3349 (REGISTER_BYTES, REGISTER_BYTE, REGISTER_RAW_SIZE,
3350 MAX_REGISTER_RAW_SIZE, REGISTER_CONVERTIBLE,
3351 REGISTER_CONVERT_TO_VIRTUAL, REGISTER_CONVERT_TO_RAW): Float regs
3352 are now 10 byte extendeds, not 8 byte doubles.
3353 (FRAME_CHAIN_VALID): Make this config-dependent, since it differs
3354 for nindy versus vxworks targets. FIXME, this should possibly go
3355 in the target vector.
3356 (EXTRA_FRAME_INFO, INIT_EXTRA_FRAME_INFO): Cache both
3357 frame_saved_regs and arg pointer with each frame.
3358 (FRAMELESS_FUNCTION_INVOCATION): New leafproc support.
3359 (FRAME_ARGS_ADDRESS): Use cached result.
3360 (FRAME_ARGS_ADDRESS_CORRECT): New, avoids g14 guessing.
3361 (FRAME_FIND_SAVED_REGS): Change arg to subsidiary fn.
3362 (PRINT_RAMDON_SIGNAL): Call print_fault.
3363 (POP_FRAME): Now works.
3365 * tm-nindy960.h: Break this off tm-i960.h. NINDY-specific
3366 option parsing and startup; STACK_END_ADDR, FRAME_CHAIN_VALID,
3367 BREAKPOINT, and DECR_PC_AFTER_BREAK are here.
3368 (ADDITIONAL_OPTION_HANDLER): use target_load, not
3371 * tm-vxworks960.h: Break this off tm-i960.h. VxGDB specific
3372 startup; DECR_PC_AFTER_BREAK, and FRAME_CHAIN_VALID are here.
3374 * valarith.c (value_subscripted_rvalue): Avoid handling
3375 floats and doubles specially; it gave alignment errors. Lint.
3377 * valops.c (value_of_variable, value_of_this): Error if unknown
3380 * valprint.c (print_floating): Bcopy rather than pointer-deref,
3381 to avoid alignment problems.
3382 (value_print): Handle unknown value address.
3383 (cplus_val_print): Two args are ignored; remove them. Change caller.
3384 (val_print): Use unpack_long rather than pointer-deref.
3387 (unpack_long, unpack_double): Use bcopy rather than pointer-deref
3388 to avoid alignment problems.
3389 (value_being_returned): Error if return value unknown.
3390 (set_return_value): Add bogosity warning, FIXME. *
3392 * TODO: A woman's work is never done.
3394 * Makefile.dist: Distribute REMOTE_OBS into tconfig files.
3395 Separate INCLUDE_CFLAGS for use with lint. Add LINTFILES.
3396 Add ieee-float.o to OBS.
3397 * tconfig/{nindy960,vxworks68,vxworks960}: Include the desired
3398 REMOTE_OBS remote-interface files in the TDEPFILES and TM_FILE.
3399 * tconfig/i960: FIXME. Half-merge, produce warning if config'd.
3401 Changes to generalize the VxWorks RPC protocol slightly, to handle
3402 i960 as well as 68000.
3404 * vx-share/dbgRpcLib.h (VX_SOURCE_STEP): Add.
3405 * vx-share/reg.h: Produce i960 regs #ifdef I80960
3406 * vx-share/xdr_ptrace.c: Skip FPA registers if 960.
3407 * vx-share/xdr_rdb.h: Add SOURCE_STEP struct and xdr decl.
3408 * vx-share/xdr_rdb.c: Add xdr_SOURCE_STEP routine.
3409 * vx-share/xdr_regs.c: Add xdr_regs, xdr_fp_status, xdr_ext_fp
3410 for i960. Change xdr_vectors to xdr_opaques for 68k registers,
3411 so they will move in target byte order rather than network
3412 byte order (happens to be the same).
3414 Mon Feb 25 03:41:44 1991 John Gilmore (gnu at cygint.cygnus.com)
3416 * tm-convex.h (END_OF_TEXT_DEFAULT): Remove #if 0'd block.
3418 Sun Feb 24 00:55:53 1991 John Gilmore (gnu at cygint.cygnus.com)
3421 Add contribution lines to various files, showing where they
3424 * breakpoint.c (break_insn, check_break_insn_size,
3425 read_memory_nobpt): Remove to mem-break.c.
3427 * xm-*.h, param-no-tm.h, tm-29k.h, valprint.c: Change BYTE_ORDER to
3430 * tm-29k.h (STAB_REG_TO_REGNUM): Warn user if symbol table
3431 entry has bad register number. This change is not
3432 tested in this release, FIXME.
3434 * frame.h: Eliminate Frame_unknown in favor of a simple zero.
3437 * value.h: Force value's contents field to be aligned to hold
3438 at least a double or a long long (if supported). This avoids
3439 doing bcopy's in and out of the contents field.
3441 (step_1): Avoid coredump under obscure circumstances when we
3444 * symtab.h (misc_info): Add field to misc function vector for
3445 any kind of cached information the target code desires. AMD
3446 29000 uses this to avoid repeating examine_function_prologue's.
3448 * coffread.c: Lint. Remove static symfile, read_section_header.
3449 core.c (have_core_file_p): Lint: remove.
3450 expprint.c (print_subexp): Lint.
3451 infptrace.c, valops.c, valprint.c: lint.
3453 Roll in changes from vxgdb-5.0.1:
3455 * symtab.h: Comment byte order of each address class. Add
3456 LOC_LOCAL_ARG for frame-relative args (960).
3457 expread.y: Use LOC_LOCAL_ARG where LOC_ARG is used.
3458 symtab.c, symmisc.c: ditto.
3460 * infrun.c (init_wait_for_inferior): Clear stop_signal.
3462 * remote.c (remote_resume): Error if resume with a signal.
3464 * symfile.c (prim_record_misc_function): Clear misc_info.
3465 (fill_in_vptr_fieldno): Check stub type of arg.
3467 * valops.c (value_cast): Avoid looking up names of types whose
3468 name we don't know, to prevent coredump. Sun CC produces typedef
3469 rtx and the name of *rtx is zero...
3471 Mon Feb 18 21:16:25 1991 John Gilmore (gnu at cygint.cygnus.com)
3473 Roll in changes from final AMD 29000 port (Tiemann).
3475 tconfig/am29k: Add COFF_ENCAPSULATE and TARGET=TARGET_AM29K
3476 for ../include/a.out.encap.h. This might not work now that BFD
3477 is separately compiled. Instead, BFD support for encap will have
3478 to translate machine type 29k into the right COFF_MAGIC.
3480 * infcmd.c: Remove references to inferior_pid that aren't used
3481 in actual ptrace calls; use target_has_execution, etc.
3482 (have_inferior_p): Remove function.
3483 (program_info): Print target info rather than "process number";
3484 avoid gratuitous messages unless from_tty.
3485 (run_stack_dummy, finish_command): Set proceed_to_finish.
3486 infrun.c: Remove inferior_pid refs. Decl & init proceed_to_finish.
3487 main.c: Lint. Lose have_inferior_p().
3488 inferior.h (have_inferior_p): Remove, lint.
3489 (proceed_to_finish): Add flag to ask that all regs be saved
3490 by normal_stop, for the few commands that need it, speeding up
3491 serial I/O. Add comments to stop_registers.
3493 * remote-eb.c: Remove newline from breakpoint message we grep
3494 for. Never time out when running the user program.
3498 Wed Feb 13 15:34:40 1991 John Gilmore (gnu at cygint.cygnus.com)
3500 Roll in changes from vxgdb-5.0.1:
3502 * dbxread.c (read_dbx_symtab): If we encounter a "FORTRAN COMMON"
3503 symbol in its raw form, we are processing an unlinked ".o" file.
3504 See if the target environment has assigned it an address, using
3505 target_lookup_symbol (VxWorks does), and enter it into the symtab
3508 * tm-vxworks.h (FRAME_CHAIN, FRAME_CHAIN_VALID): Override usual
3509 68k versions for a simpler version that assumes zero FP at bottom.
3510 Fixes bug of truncated stack reports.
3512 * target.h (target_lookup_symbol): Define this routine's args
3513 and result, finally.
3515 * target.c (nosymbol): Default routine for target_lookup_symbol.
3516 (target_default): Default lookup_symbol and call_function too.
3517 (files_info): Only print has_all_memory warning if a non-dummy
3520 * remote-vx.c (vx_read_register, vx_convert_to_virtual,
3521 vx_convert_from_virtual): If target does not have floating point,
3522 zero register "values", and avoid doing cross-net conversions.
3523 (vx_lookup_symbol): Rename net_lookup_symbol, add to vectors.
3524 (vx_open): Rearrange code that attaches to target and reads
3525 symbols for all loaded modules, to work if some of the modules
3526 are not accessible. Add symbol_stub() and add_symbol_stub()
3527 as callbacks from catch_errors(). Allow connect attempt to be
3528 interrupted painlessly with ^C (FIXME, there are still some bugs
3529 if the interrupt happens during symbol reading.). Print
3530 final message with puts_filtered, since symbol messages are
3535 * main.c (catch_errors): Only print errstring if non-null.
3536 (command_loop): Avoid an ioctl per command to test ISATTY.
3538 * remote-vx.c (net_load): make static; avoid sophomoric msg.
3539 (vx_xfer_memory): Return correct result!
3540 (vx_files_info): Indicate whether target has float or not.
3541 (vx_lookup_symbol): Complain, not error, if target gone.
3542 (vx_open): Print "Connected" msg before disabling immediate-quit.
3543 [FIXME: lookup_symbol and vx_open changes need testing.]
3545 target.c, remote-eb.c, inftarg.c, am29k-opcode.h, target.h,
3546 tm-29k.h, tmm-vxworks68.h, symfile.c, gdb-int.texinfo: Add
3547 contributor lines and update copyrights to 1991.
3549 Changes from an attempted H-PUX host port:
3551 * infptrace.c (PT_ATTACH, PT_DETACH): Handle HP/UX, which
3552 defines PT_ATTACH and PT_DETACH but not PT_KILL.
3553 * remote-eb.c (eb_open): Misplaced endif kills sysv H/PUX.
3554 * remote-vx.c: include <sys/time.h> for HPUX.
3555 * hp300hpux-xdep.c (fetch_core_registers): Rewrite old
3556 "core_file_command" routine to BFD regime. May not work yet.
3558 Attempted port of "gdb-3.4 Van Jacobson xgdb" to modern gdb.
3560 * xgdb.c: Replace X10 version with some VJ version.
3561 (FIXME: Its copyright assignment is not on record.)
3562 * xgdb.c: Update include files to X11R4 (Xaw crud).
3563 (xgdb_display_source, create_text_widget): fix call to
3564 get_filename_and_charpos. Rewack source window stuff for X11R4
3565 (gleaned from include files, and "nm's" of binary libraries, since
3566 I had no doc available).
3567 (append_selection, append_selection_word): Disable with FIXME
3568 since R4 changed interface here.
3569 (create_buttons): Add back the old set of buttons.
3570 (xgdb_create_window): Fix call to XtInitialize (&argc not argc).
3572 * Makefile.dist (xgdb, xgdb-init.c): Update for X11R4 on Suns.
3573 Roll VERSION to 3.94 (not yet final though).
3575 Sat Feb 9 09:46:25 1991 John Gilmore (gnu at cygint.cygnus.com)
3577 * obstack.h (obstack_ptr_grow, obstack_ptr_grow_fast,
3578 obstack_int_grow, obstack_int_grow_fast): Eliminate
3579 cast on left of assignment, which gives MIPS cc fits and is
3582 * sparc-pinsn.c (print_insn): Eliminate 'set' test, subsumed by
3583 F_ALIAS. Use printf, not fprintf, when not passing a file
3585 (compare_opcodes): Check that identical instructions have
3586 identical opcodes, complain otherwise.
3588 * sparc-opcode.h (st %fsr): Fix opcode "lose" mask. This
3589 was reported by Roland McGrath.
3590 (unimp): Only match if exactly zero instruction. (Roland)
3591 (branches and traps): Generate all variations of these
3592 instructions with macros, based on a single call that defines
3593 each condition name and its binary representation.
3594 (set): Turn on alias bit, to avoid test in sparc-pinsn.c.
3596 * valprint.c (val_print_fields): Take, and use, format parameter.
3597 This means that "p/x struct" again prints the elements in the
3598 desired format. Changed callers.
3600 * stack.c (frame_info): Use filtered output, and indicate wrap
3601 points. Remove kludgy formatting designed to avoid line wrap.
3603 * utils.c (wrap_here): If the line is already full (because
3604 we had printed a long indent or long wrapped string), do an
3605 immediate newline-and-indent.
3607 * m68k-pinsn.c (print_insn_arg): Bugfix from
3608 ntmtv!thompson@ames.arc.nasa.gov (Mike Thompson): 'bkpt #0'
3609 instruction is incorrectly disassembled as bkpt #8.
3611 * dbxread.c (end_psymtab): Bugfix from Peter Schauer
3612 <pesrem@regent.e-technik.tu-muenchen.de>: If you want to set a
3613 breakpoint in a *.y file gdb will say Reading in symbols for *.y...
3614 and then will dump core (sometimes). I traced it back to an
3615 uninitialized symfile_name in psymtab_to_symtab.
3616 (const_vol_complaint): Add quotes to message.
3617 (define_symbol): Only believe line number if gcc_compiled.
3618 Avoid allocating symbol if we will not return it.
3620 Add target strata support so that newly established targets go
3621 into their right place in the target stack (e.g. a new exec file
3622 doesn't wipe out the ability to access the running process).
3624 * target.h, core.c, exec.c, inftarg.c, remote-eb.c,
3625 remote-nindy.c, remote-vx.c, remote.c, target.c: Add to_stratum
3626 and initialize it properly in all the targets.
3628 * target.h: Document strata. Change return type of push_target.
3630 * target.c (nomemory): new function for dummy memory access.
3631 (tcomplain): Rename complain, now also used in symfile.c.
3632 (push_target): Push targets within strata. New return value shows
3633 whether new target is on top of stack or not. Always keep dummy
3635 (target_files_info): Ignore dummy target.
3637 * core.c (core_open): Warn user, and skip accessing file, if the
3638 core target is not the topmost target in the stack.
3639 * remote-nindy.c (nindy_create_inferior): Avoid unpush_target, now
3642 * remote-vx.c: Remove vx_prepare_to_store from vxworks memory
3643 target_ops, it doesn't belong there since we have no regs there.
3644 Change name of target from machine => memory to clarify.
3646 Thu Feb 7 16:32:09 1991 John Gilmore (gnu at spiff.cygnus.com)
3648 * Freeze version 3.93 for release.
3650 * Makefile.dist: Handle vx-share and nindy-share subdirs
3651 properly when building gdb.tar.Z.
3653 * symtab.c: lint; add no_symtab_msg to consolidate the messages
3654 printed in various places, so I could change just one copy.
3656 * dbxread.c, coffread.c: Change references to bfd->iostream
3657 to cast to FILE *, now that BFD avoids needing types defined
3658 in other header files.
3660 Tue Feb 5 21:39:35 1991 John Gilmore (gnu at cygint.cygnus.com)
3662 * command.c, dbxread.c, expprint.c, infcmd.c, infptrace.c,
3663 infrun.c, printcmd.c, remote-nindy.c, source.c, sparc-tdep.c,
3664 sparc-xdep.c, symfile.h, symmisc.c, utils.c, valprint.c: Lint
3665 (actually gcc -Wall).
3667 * dbxread.c: Remove first_global_sym, last_global_sym, since
3668 they are never referenced.
3670 * defs.h (baud_rate): Declare.
3671 main.c: Define it, and add the -b option to set it.
3673 * gdb-int.texinfo: Add text on how to define a new host or target
3674 architecture, prompted by Per Bothner's questions about MIPS
3677 * gdb.texinfo: Document "complaints". Change doc of -q since
3678 gdb no longer prints the copyright and blurb if you specify a file
3679 name to be debugged (just like Emacs). Add doc for Nindy-specific
3680 command line flags for specifying target serial port and such.
3681 Update copyright to 1991.
3683 * gdbcore.h: Remove a large mass of now-useless crud, since BFD
3684 has taken over for us the job of ripping up executable files. The
3685 crud caused Per Bothner's port to not compile.
3687 * infrun.c (normal_stop): Avoid printing "Program exited
3688 normally" if we are in batch mode. This allows a GDB which
3689 executes a program on a target system, to behave like a Unix
3690 command (input from stdin, output to stdout, no extraneous
3693 * main.c (main): Allow additional machine-dependent command line
3694 options to be specified with the ADDITIONAL_OPTIONS,
3695 ADDITIONAL_OPTION_CASES, ADDITIONAL_OPTION_HELP, and
3696 ADDITIONAL_OPTION_HANDLER macros. Also allow machine-dependent
3697 processing to occur just before the main loop with
3698 BEFORE_MAIN_LOOP_HOOK.
3699 (main): If a "core file" argument is specified, and it is not a
3700 core file, try it as a process ID to attach.
3701 (symbol_completion_function): Attempt to cope with
3702 "show screen-" TAB, not very successfully. This needs more work,
3704 (batch_file): New function, returns whether we are reading
3705 commands from an interactive tty on stdin, or from somewhere else.
3706 Called by normal_stop since it doesn't get from_tty passed down
3707 to it like many commands do.
3709 * remote-nindy.c: Handle command line options for nindy
3711 (nindy_before_main_loop): Prompt user for tty name if they
3712 don't specify it before getting to the interactive command loop.
3714 * tm-i960.c: Add ADDITIONAL_OPTIONS, etc, to handle -O, -brk,
3715 and -r command line options. Also add hook before main loop
3716 to make it easy to specify a tty.
3718 * TODO: More things to do, one done.
3720 Mon Feb 4 23:57:39 1991 John Gilmore and Mike Tiemann (at cygint.cygnus.com)
3722 * dbxread.c: Make complaint() calls pass pointer, not struct.
3723 Add complaints about badly formatted C++ type information
3724 (const/volatile indicator, and parse errors resulting in
3725 error_type). Fix C++ virtual member fn comment.
3726 (read_struct_type): Avoid bumping pointer if we got a parse
3727 error; this prevents our walking beyond the end of a string.
3728 Terminate loop on null char as well as semicolon.
3729 (process_one_symbol): Fix the LBRAC fix so that it uses the
3730 last previous SLINE, FUN, or SO record's PC address. C++ debug
3731 symbols did not have SLINE records in a useful order compared
3732 to the LBRAC records.
3733 (define_symbol): Handle "catch" records.
3735 * symtab.c (check_stub_type): Added new complain
3736 `stub_noname_complain' and added a consistency check to
3737 keep the debugger from crashing when finishing from an
3738 exception frame. A real fix will be needed later.
3740 Sat Feb 2 10:43:05 1991 John Gilmore (gnu at cygint.cygnus.com)
3742 * infcmd.c (attach_command): Make global.
3744 * Makefile.dist (REMOTE_OBS): Make these compile by default,
3745 but make them easy to comment out. Perhaps later they should
3746 be enabled by what CPU you configure for? FIXME.
3747 (VERSION): Roll to 3.93.
3748 (pinsn.o): Remove rule for obsolete file.
3749 (dbxread.o,coffread.o,mipsread.o): Use ${srcdir} explicitly.
3751 Run down a problem that manifested by printing the wrong function
3752 name in stack traces of read_ofile_symtab. Turned out that the
3753 problem was the SunOS 4.1.1 (and previous) C compiler outputs
3754 the LBRAC symbol with an address in the *data* segment, which
3755 blew our binary search through the blocks.
3757 * dbxread.c: Use the complain() facility consistently to bitch
3758 about problems in the symbol file we are reading.
3759 (finish_block): Add code to check the nesting of the blocks;
3760 complain and Procrust them to fit if wrong.
3761 (make_blockvector): Check the order of the blocks, complain
3762 [but don't cope] if wrong.
3763 (process_one_symbol): ifndef SUN_FIXED_LBRAC_BUG, check LBRAC
3764 symbols to be sure their PC value is greater than the last SLINE
3765 (line number) symbol we've seen, complaining and adopting the
3766 SLINE PC value if wrong.
3768 * symfile.h (struct complaint, complaint_root, complain,
3769 clear_complaints): Add.
3770 * symfile.c (complain, complaint_root, clear_complaints): Add
3771 facility to deal with non-fatal complaints and to regularize their
3773 (symbol_file_add): Clear complaint counters to allow new complaints.
3774 (initialize_symfile): Add 'set complaints' and 'show complaints'.
3776 * dbxread.c (dbx_symfile_read): Remember the address and size
3777 of the string table for the main symbol file, so we won't read it
3779 (dbx_psymtab_to_symtab): Fix the check for main symbol file,
3780 to avoid reading the string table yet again. Lint.
3781 (throughout): Improve filtered output, including word wrap.
3782 (read_range_type): Improve Bothner's fix to handle other types too.
3784 * utils.c: Improve line wrap implementation. Handle unlimited
3785 width by making chars_per_line unsigned.
3786 (puts_filtered): New, easy, function.
3788 * defs.h (puts_filtered): add.
3790 * mipsread.c (compare_symbols, sort_symtab): Remove these fns,
3791 call the identical sort_symtab_syms() in symfile.c instead.
3793 * expread.y: Suggest the `file' command rather than `symbol-file'.
3795 * command.h (enum var_types): Add zinteger for seroable
3797 * command.c (do_setshow_command): Handle var_zinteger. Restructure
3798 nested if's into a switch.
3800 * breakpoint.c (bpstat_print): If bpstat "print" flag is not set,
3801 we did not stop because of a breakpoint (it must have been for
3802 some other reason, like a "stepi"), so don't print anything.
3804 * symtab.c: Include <sys/types.h> all the time. Now that BFD
3805 doesn't include <sys/types.h>, old SunOS's require it for
3808 Sat Feb 2 10:39:15 1991 Per Bothner (bothner@cs.wisc.edu)
3810 A test port of gdb-3.92.6 to the Sony NEWS.
3813 Don't normally link in remote- or vx stuff.
3814 Some of it doesn't compile, and it wastes space for 99% of the users.
3815 Remove reference to no-longer-used HAVE_VPRINTF.
3816 Fixed BFD_DEP typo to BFD_DIR.
3818 Fix cast in arg to bfd_h_getlong.
3819 Make char *prefix be const.
3820 Fix how certain range types are mapped into builtin unsigned int types.
3822 Remove 2 #includes. They cause errors (on Sony, at least),
3823 and aren't needed (they wern't in earlier versions).
3825 print_address_symbolic should never demangle labels
3826 (since it prints *assembler-level* labels).
3828 [This was superseded by the change to printcmd below.]
3831 Add some "volatile" return types to avoid warnings.
3832 If MISSING_VPRINTF add vprintf function and not just macro
3833 (since vprintf is used in printcmd.c).
3835 Unless __GNUC__, use obstack_grow instead of obstack_ptr_grow.
3836 (The latter isn't grokked by some PCC-based compilers.)
3838 [This change is in abeyance, we prefer to fix obstack_ptr_grow.]
3840 Make chunk size of dont_print_obstack 32*4 instead of default 4096.
3841 * nindy-share/coffstrip.c
3842 Added some forward declarations (otherwise, gcc complains
3843 about implicit extern redefined as static).
3845 Sun Jan 20 02:38:19 1991 John Gilmore (gnu at cygint.cygnus.com)
3847 Changes inspired by Per Bothner:
3848 * printcmd.c (print_address_symbolic): Take additional parameter
3849 specifying whether to demangle.
3850 (print_address): Pass in asm_demangle to control demangling.
3851 (print_address_demangle): New fn, takes explicit arg to control
3853 * utils.c: Add new vars demangle and asm_demangle, and let them
3855 (fputs_demangled): If !demangle, just print the argument.
3856 (fprint_symbol): If !demangle, just print raw symbol.
3857 * valprint.c (val_print): Call print_address_demangle rather than
3858 print_address, to cause demangling to depend on the global
3859 rather than assembler-level demangling setting.
3860 * WHATS.NEW, gdb.texinfo: Document.
3862 * main.c (show_command): Show all settings if no arg.
3863 (initialize_main): Make "info set" the same as naked "show".
3864 * command.c (cmd_show_list): Handle prefix commands in the
3865 list, and print the name of the setting as well as its English
3866 description and value.
3868 Allow gdb functions to specify where a line should wrap if it
3869 exceeds the size of a terminal line. Use it to make the output
3871 * utils.c (set_screen_width_command): New fn, mallocs a buffer
3872 of the right size when screen width changes.
3873 (set_screensize_command, screensize_info): Remove #if 0'd fns.
3874 (wrap_here): New fn, indicates a point in the output where we
3875 should wrap the line rather than just letting it overflow at a
3877 (fputs_filtered): Implement wrapping.
3878 (n_spaces): New fn, returns a pointer to N spaces.
3879 (print_spaces_filtered): Use n_spaces.
3880 * defs.h (n_spaces): Declare.
3881 * stack.c (print_frame_info): Wrap with 4-space indent after
3882 fn name and before filename and line number.
3883 * printcmd.c (print_frame_args): Wrap with 4-space indent
3884 before each argument name is printed.
3885 * valprint.c (value_print): Wrap with no indentation before
3887 (val_print_fields): Wrap with indentation relative to nesting
3888 level before each field name.
3889 (val_print): Wrap with nesting indentation before array elements.
3890 * command.c (do_setshow_command): Avoid extra newlines,
3891 wrap with 4-space indent around values printed, end with period.
3892 * WHATS.NEW, gdb.texinfo, gdb-int.texinfo: Document.
3894 * breakpoint.c (breakpoint_1): Implement addressprint for
3895 "info breakpoints" display. Change file name and line number
3896 format to " at file:nnn" rather than " (file line nnn)".
3897 * gdb.texinfo: Document.
3900 Fri Jan 18 07:21:25 1991 John Gilmore (gnu at cygint.cygnus.com)
3902 Frozen for gdb-3.92.6 release.
3904 README, WHATS.NEW: Update for 3.92.6 release.
3906 tconfig/{altos, i386v, i386v32, m88k, umax}: Eliminate
3907 coffread.o from configs since it is now built by default.
3908 tconfig/{3b1, altosgas, arm, convex, hp300bsd, hp300hpux,
3909 i386v-g, i386v32-g, isi, merlin, news, news1000, np1, pn,
3910 pyramid, symmetry, vax, vxworks68}: Eliminate dbxread.o
3911 from configs since it is now built by default.
3913 Makefile.dist: Update for release 3.92.6. Handle files that
3914 have been moved to ../include, ../getopt, or ../bfd. Add
3915 saber.suppress and tests directory. Add config.status to
3916 the release (it will say "none").
3918 coredep.c: Minor formatting fixes.
3920 These changes were made in early December but only checked in now:
3921 * nindy-share/Onindy.c, nindy-share/coffstrip.c,
3922 nindy-share/nindy.c: lint
3923 * nindy-share/nindy.c (ninStopWhy): Don't byteswap the
3924 register values coming back from the target; we store values
3925 in target byte order everywhere.
3927 Wed Jan 16 19:01:37 1991 John Gilmore (gnu at cygint.cygnus.com)
3929 * am29k-opcode.h, am29k-pinsn.c: Add 29050 opcodes.
3931 * valprint.c (cplus_val_print, val_print_fields): New functions,
3932 which print C++ objects. They conspire to avoid printing a
3933 virtual base class more than once, following all the twists and
3934 turns of C++ virtual base rules.
3935 (val_print): Call the above rather than do it by hand.
3937 * symfile.c (symbol_file_add): Only reset symfile_mtime for main
3938 symbol file, not for added files like shared libs. This really
3939 needs to be generalized to a timestamp per file.
3941 * core.c (cleanup_core): Avoid coredump if no core file.
3943 * config.gdb: Accept -host or -target in place of +host or
3946 * coffread.c (find_linenos): Avoid desupported BFD interface
3947 to line numbers. We still read them manually rather than using
3948 BFD's "generic" features.
3950 * gdbrc.tex, threecol.tex: Add GDB reference card and its
3952 Makefile.dist: Add refcard to OTHERS list for creating tar files.
3954 * Makefile.dist: Eliminate use of $< in explicit targets.
3956 * readline/Makefile: Use $< rather than $*.c, which does not
3957 include the VPATH in GNU Make.
3959 * tconfig/i960-bout, tconfig/i960-coff: These are identical
3960 copies of tconfig/i960, added for global configuration
3961 compatability. All i960 versions can read both coff and b.out.
3963 * tm-88k.h: Fix multiline macro that lacked \'s. Remove
3964 COFF_FORMAT and COFF_CHECK_X_ZEROES since these are now handled
3967 * TODO: Think of more things to do.
3969 Wed Jan 2 19:09:29 1991 John Gilmore (gnu at spiff.cygnus.com)
3971 tconfig/{am29k,i960,sun2*,sun3*,sun4*}: Eliminate config
3972 of sdb versus dbx debug symbols. Add kludge for 68881 80-bit to
3973 64-bit float conversion.
3975 tconfig/sun4, tconfig/sun3, xconfig/sun4, xconfig/sun3: Make
3976 equivalent to sun?os4 so global config works.
3978 Wed Jan 2 18:20:51 1991 John Gilmore (gnu at spiff.cygnus.com)
3980 Fix from Eberhard Mattes <mattes@azu.informatik.uni-stuttgart.de>
3982 * main.c: Only declare linesize once; declare pagesize not at
3983 all, since it is never used.
3984 (main): Clear newly allocated line before it is used.
3986 Fri Dec 28 00:13:42 1990 John Gilmore (gnu at cygint)
3988 Further stabilization for the Intel 960.
3990 * Makefile.dist: Parameterize the location of the "include"
3991 and "bfd" directories, as well as "getopt". Add symfile.c.
3992 Link in both dbxread and coffread. Fix up "make depend" to
3993 rewack the locations of include, bfd, and getopt in its output.
3995 * README: Document moving include files, improve some of
3998 * coffread.c: Move common code out to symfile.c. Change
3999 symbol_file_command style interface to use new *_symfile_init
4000 and *_symfile_read interface under BFD. Use BFD internal
4001 info to locate line table, symbols, etc.
4003 * core.c (core_fetch_registers): Rename to get_core_registers
4004 to avoid confusion with fetch_core_registers.
4005 (register_addr): Move to coredep.c, which is already machine
4006 dependent. This leaves core.c pretty clean of dependencies.
4008 * coredep.c (register_addr): Accept this routine from core.c.
4010 * dbxread.c: Move common code (with coffread.c, etc) into new
4011 symfile.c. Each psymtab now contains a pointer to the
4012 format-dependent function that knows how to read it in. Make
4014 (dbx_psymtab_to_symtab): Renamed from psymtab_to_symtab_2.
4015 (process_one_symbol): Add code to complain about a "compiler bug
4016 we muzzle here", if we actually see it.
4018 * eval.c (evaluate_subexp): Insert missing "break" statements
4019 in code that determines whether a variable is an lvalue in
4020 memory, register, or whatever. I detected this via a compiler
4021 bug in which it *almost* mashed out the whole switch statement.
4023 * gdb-int.texinfo: Add minor sections on configuring gdb for
4024 release, and about the README file.
4026 * infcmd.c (registers_info): Fix formatting somewhat. Still
4027 not as pretty as before, but it handles byte swapping.
4029 * remote-nindy.c: If data cache routines are interrupted while
4030 waiting for the remote end, be sure that any uninitialized cache
4031 blocks are on the free list, not on the valid list!
4033 * symfile.h: Flesh out this header file with all the various
4034 routines and variables that have been merged in from dbxread.c
4035 coffread.c, and symtab.c to symfile.c.
4037 * symfile.c: New file, containing code common to dbxread.c,
4038 coffread.c, and some code from symtab.c. All generic code for
4039 reading symbol files should be in here now.
4040 (unrecord_misc_function): Remove unused function.
4042 * symtab.h: Remove file-reading things to symfile.h.
4044 * symtab.c: Remove file-reading things to symfile.c.
4046 * tm-i960.h: Fix FRAME_CHAIN types; define PRINT_RANDOM_SIGNAL
4047 to decode i960 fault types.
4049 * target.h, remote.c, remote-eb.c, remote-vx.c, remote-nindy.c,
4050 target.c: Change type of the "resume" function from int to void,
4051 since its result was never used.
4053 Sat Dec 22 02:51:40 1990 John Gilmore (gnu at cygint)
4055 * main.c: Replace "stupid" with "caution"; you now "set caution
4058 * printcmd.c (print_scalar_formatted): Fix typo in 'g' format
4060 * infcmd.c (do_registers_info): Call val_print to deal with the
4061 byte order of the registers being printed. FIXME, this makes
4062 the formatting of the output uglier.
4064 * infcmd.c (wait_for_inferior): If PRINT_RANDOM_SIGNAL is
4065 defined, call it for signals the debugger doesn't itself use.
4066 The i960 uses this for more detailed fault information.
4068 * remote.c (remote_open): If arg is null, print help rather than
4071 * sparc-xdep.c (register_valid): Avoid declaring size, since
4072 various modules will think of various sizes depending on the
4073 architecture of their tm-file. FIXME, we need protection against
4074 actually entering one of those modules, which would clobber
4075 storage if not for the target architecture compiled into gdb.
4077 * stack.c (up_command, down_command): Always print the frame
4079 (up_silently_command, down_silently_command): New commands
4082 * i960-pinsn.c (reg), i960-tdep.c: Lint.
4084 * i960-tdep.c (i960_frame_chain_valid): Lookup_symbol now takes
4085 more parameters than it used to.
4087 * findvar.c (registers): Increase slop to 256 bytes, which should
4088 protect us against even most RISC machines with large register
4090 (locate_var_value): Move declaration inside related ifdef.
4092 * remote-nindy.c (): Use TIOCSETN rather than TIOCSETP
4093 throughout, to avoid throwing away buffered input from the board.
4094 (nindy_wait): Supply_register takes addr_of_value, not value.
4095 (i960_print_fault): Renamed from i80960_fault.
4096 (nindy_fetch_registers): Avoid have_regs stuff, just get them.
4097 (nindy_store_registers): Avoid regs_changed stuff, just stuff
4099 (nindy_create_inferior): Don't bother to write PC_REGNUM since
4100 we can set the PC in the call to proceed(). Unpush nindy_ops
4101 before pushing it on top, to avoid message to user. Eliminate
4102 commentary from Unix machines that just misleads here.
4103 (reset_command): Fix error message to suggest target command.
4105 Wed Dec 19 11:03:56 1990 John Gilmore (gnu at cygint)
4107 Release 3.92.5 as frozen.
4109 Stabilize the merged release...with help from lint, Saber C,
4112 Everywhere: Add include files needed to declare return types
4113 of functions called.
4115 * gdb.texinfo: Roland Pesch is documenting gdb, glory be!
4117 * breakpoint.h: Add undeclared breakpoint functions, and some
4118 functions for display handling since I couldn't think of a better
4121 * breakpoint.c (insert_breakpoints): Make code for disabling
4122 shared library bkpts more likely to work. It's used when we
4123 rerun a program and stop before the shared library has been
4125 (breakpoint_cond_eval, bpstat_stop_status): Pass arg as int,
4126 cast from pointer, so it squeezes through catch_errors.
4127 (bpstat_stop_status): Fix logic broken some time ago. We now
4128 always create a bpstat if the stop address matches a breakpoint,
4129 even if we don't stop there -- just like the old code used to do
4130 before I got my fingers into it (sigh).
4131 (breakpoint_1): Print "ignore count" after "stop only if"
4132 condition, since that's how it actually works.
4133 (mention): Handle watchpoints as well as breakpoints.
4134 (watch_command): use set_raw_breakpoint and mention to do most
4135 of the work (and initialize all the fields!). Only pass one
4136 arg to parse_c_expression, since that's all it takes.
4138 * command.c (not_just_help_class_command): Rename arg to args
4139 since we ignore "unused argument" warnings on vars named "args".
4140 inflow.c (child_terminal_info): ditto.
4141 infptrace.c (kill_inferior): ditto
4142 main.c (catch_errors, version_info, quit_command, pwd_command,
4143 source_command, dump_me_command, editing_info,
4144 set_history_size_command, set_history, show_history,
4146 stack.c (locals_info): ditto
4147 target.c (target_files_info): ditto
4148 valprint.c (set_input_radix, set_output_radix): ditto
4150 * core.c: Remove old variables for handling core and exec file
4151 sections (data_start, data_end, stack_start, stack_end,
4152 reg_stack_start, reg_stack_end, reg_stack_offset, text_start,
4153 text_end, exec_data_start, exec_data_end, text_offset,
4154 exec_data_offset, data_offset, stack_offset). They're
4155 superseded the more general build_section_table and
4157 (get_exec_file): Mention the `file' command.
4158 (read_memory_check): Rename to memory_error, and only call it
4159 in the case of an actual error.
4160 (read_memory, write_memory): call memory_error.
4161 (core_fetch_registers): Register section name is ".reg".
4163 coredep.c: Remove a bunch of crud now that all this file does
4164 is pull the registers out of a core file.
4165 (fetch_core_registers): Rewrite to actually work, I hope.
4167 dbxread.c: Use a.out.gnu.h, not system a.out, now.
4168 Replace index() with strchr(). Remove all the pre-BFD macro
4169 definitions for accessing the symbol file.
4170 (struct dbx_symfile_info): Encapsulate the information that
4171 dbx_symfile_init needs to pass to dbx_symfile_read in this
4174 (dbx_new_init, dbx_symfile_init, dbx_symfile_read,
4175 dbx_symfile_discard): Rearrange symbol file reading to divide
4176 the format-specific part from the format-independent part,
4177 leaving the format-independent part such as file name expansion
4178 and opening in symtab.c. This replaces
4179 partial_symbol_file_open and partial_symbol_file_read.
4180 Symbol_file_read, add_file, add_file_target_command,
4181 add_file_addr_command move to symtab.c. Pass an explicit
4182 "mainline" flag for when reading the main symbol table, rather
4183 than relying on the offset address to be zero or nonzero.
4185 (dbx_symfile_read): Don't allow void *'s to be printed as
4187 (SWAP_SYMBOL): Use bfd routines to byte-swap the symbols.
4188 (ADD_PSYMBOL_TO_LIST): Make the "function call rather than
4189 macro" debug version really work.
4190 (read_dbx_symtab): Remove unref'd parameter inclink.
4191 Avoid swapping N_SLINE symbols, for speed.
4192 Merge N_TEXT!N_EXT case with the other external symbol
4193 definitions' case. Add comments.
4194 (start_psymtab): Allocate the symfile name in the psymtab on
4195 the psymbol_obstack, rather than using the caller's storage.
4196 (end_psymtab): Only allocate a dependencies list if there are
4198 (psymtab_to_symtab_2): Use BFD when reopening file to read
4199 its symbols for real.
4200 (read_struct_type): Add FIXME comments where it needs work
4202 (read_huge_number): Add FIXME about overflows.
4203 (read_range_type): Add FIXME about comparing a long to 1<<32.
4205 * coffread.c: Minor changes to move things closer to the new
4206 regime with symtab.c and dbxread.c Major work is still needed
4209 * exec.c (exec_file_command): Remove old variables (see core.c
4211 (xfer_memory): If memory transfer is right at the end of a
4212 section, don't lose.
4214 * findvar.c (get_saved_register): If value is in a real
4215 register, LVAL is lval_register, not lval_memory.
4217 frame.h: Declare print_sel_frame and record_selected_frame.
4219 gdb-int.texinfo: New file, for GDB internals documentation.
4220 Very simple, unformatted doc of cleanups is there for now.
4222 gdbcore.h: Remove obsolete variables that described a.out
4223 section addresses and offsets. (See core.c above.)
4224 Declare fetch_core_registers and registers_fetched.
4226 getopt.c: Declare char *alloca(); even on SPARC.
4228 infcmd.c (run_command): Call target_kill rather than
4230 (step_command, next_command, stepi_command, nexti_command):
4231 Declare from_tty parameter even though we don't use it.
4232 (run_stack_dummy): argument BUFFER is a char array, not
4233 a pointer to REGISTER_TYPE.
4234 (finish_command): using_struct_return needed a value *,
4235 not a struct symbol *.
4237 * infptrace.c (child_xfer_memory): To avoid dependency on
4238 where sections are in memory, try PT_WRITE_D and if that fails,
4239 try PT_WRITE_I. Most Unixes don't care which you use.
4241 * infrun.c (step_resume_break_shadow): Change to array to
4242 match other breakpoint shadow storage.
4243 (clear_proceed_status): Pass address of bpstat to
4244 bpstat_clear, not the bpstat itself.
4245 (child_create_inferior): FIXME comment about if the child
4247 (start_inferior): Remove old function.
4248 (child_open): Use target_kill rather than kill_inferior.
4249 (wait_for_inferior): Ditto.
4250 (insert_step_breakpoint, remote_step_breakpoint): Use
4251 new step_resume_break_shadow.
4253 * inftarg.c (child_wait): If all child processes die,
4254 pretend that the one being waited for exited with signal 42.
4256 * main.c (command_line_input): When scanning for comments,
4257 don't coredump on unclosed quotes.
4258 (quit_command): Use target_kill rther than kill_inferior.
4259 (_initialize_main): Rename class_user from "user" to
4262 * printcmd.c (print_command_1): Initialize "fmt" if no format
4263 is specified by the user.
4264 (print_frame_args): Only add to args_printed if we are
4265 actually fetching args from the stack (avoiding undefined
4267 (_initialize_printcmd): Remove bogus \{ from string.
4269 * remote-eb.c (eb_open): Avoid coredump on no argument.
4271 * remote-nindy.c: Bring out of Intel environment into new
4272 target environment. Remove all conditional compilation on
4273 I80960. Massive hacking throughout.
4274 (nindy_xfer_inferior_memory): New routine stolen from
4276 (nindy_create_inferior): New routine pieced together, probably
4277 not quite working yet.
4278 (nindy_ops): New target_ops struct for nindy.
4280 * remote-vx.c: Use write_memory rather than target_write_memory
4281 to get error checking.
4282 (vx_add_file_command, vx_open): Use symbol_file_add rather than
4284 (vx_create_inferior): Use target_terminal_ours...
4286 * signame.c (_initialize_signame): Always initialize, since
4287 we need the table for things other than psignal.
4289 * solib.c (solib_add): Use symbol_file_add, not add_file.
4290 (solib_address): Return boolean result rather than struct
4291 pointer which nobody else knows the type of.
4293 * sparc-tdep.c, valops.c: Use write_memory rather than
4294 target_write_memory, to get error checking.
4296 * stack.c (locals_info, catch_info, args_info,
4297 get_selected_block, frame_command, up_command): Use
4298 target_has_stack, rather than have_inferior_p or
4301 * sun3-xdep.c (fetch_core_registers): Rewrite for new BFD regime.
4303 * symfile.h: New file, defining the interface between the
4304 generic and object-file-specific symbol reading code.
4306 * symtab.c: Move generic symbol-reading interface to symtab.c,
4307 from dbxread.c, coffread.c, mipsread.c, etc. Add symtab_fns
4308 table to map BFD targets to symbol-reading modules in GDB.
4309 Change index to strchr.
4310 (lookup_struct_elt_type): Use error() rather than hand-made
4311 simulations thereof.
4312 (lookup_partial_symbol): Speedup slightly when length == 0.
4313 (symbol_file_add): New function.
4314 (symbol_file_command): Call it.
4315 (symfile_open, symfile_init): New function.
4316 (add_file_target_command, add_file_addr_command): moved from
4319 * target.c (target_command): use target_kill.
4321 * target.h (target_files_info): Don't declare, never called
4324 * tm-sun2.h, tm-sun3.h (STACK_END_ADDR): Use system include
4325 files to determine stack end address.
4327 * valarith.c (value_x_binop, value_x_unop): Change error message
4328 to be more useful. Pass proper argument to value_struct_elt.
4330 * valops.c (value_assign): FIXME comment that long long
4331 bitfields will break here.
4333 * Makefile.dist: Add symfile.h, remote-nindy.c, remote-eb.c.
4334 Update `make saber_gdb' to work better.
4336 * TODO: A woman's work is never done.
4338 * cplus-dem.c, environ.c, inferior.h, infrun.c, inftarg.c,
4339 main.c, obstack.c, printcmd.c, remote-eb.c, remote-nindy.c,
4340 remote-vx.c, remote.c, solib.c, source.c, sparc-pinsn.c,
4341 sparc-tdep.c, sparc-xdep.c, symmisc.c, symtab.c, symtab.h
4342 target.c, terminal.h, tm-sparc.h, tm-sunos.h, utils.c,
4343 valops.c, valprint.c, exec.c: Lint.
4346 Wed Dec 12 23:44:15 1990 John Gilmore (gnu at cygnus.com)
4348 Continuing Intel 960 port merge of GDB.
4350 * Makefile.dist: Merge i960 "nindy-share" files. Rename
4351 malloc.h to gmalloc.h to avoid name conflicts in /usr/include.
4352 Don't ship gdb.dvi in tar file. Link gdb with init.o, not init.c.
4353 Wack over "make depend" so it handles files in subdirectories
4354 vx-share, nindy-share, bfd, and in the current directory.
4356 * blockframe.c (get_prev_frame_info): Remove fatal error
4357 if stack not defined.
4359 * core.c (core_open, core_detach): New functions that handle
4360 the old "core-file" command as "target core" and "detach" instead.
4361 (core_file_command): Call them.
4362 (core_xfer_memory): Use common routine xfer_memory.
4364 * dbxread.c: Include a.out.gnu.h, not system a.out.h.
4365 dbxread now uses bfd for everything but symbol reading itself.
4366 BFD internals are used to drag out the relevant file offsets.
4367 (partial_symbol_file_open): Change args all around for BFD.
4369 * symtab.c: Rename "value" to "val" everywhere, so we can
4371 (symbol_file_command): New command, moved from dbxread.c
4372 and coffread.c. It uses BFD to read the file, then vectors
4373 based on its type, to dbx or coff symbol readers.
4374 * symtab.h: Extern a few vars for symbol_file_command.
4376 * target.h: Breakpoint takes a char * save area, not a char **.
4378 * valprint.c (val_print): When unpacking bitfields, offset
4379 the address in gdb of the value, if it is declared with a shorter
4380 type. Remove the last "runtime kludge test" of host byte order.
4382 * utils.c: Remove old my_bfd_read routine.
4384 * stack.c (frame_info): Use target_has_stack. Print program counter
4385 register's actual name rather than "pc", since it's called the
4386 "ip" (instruction pointer) on the i960 (sigh).
4388 * target.c (target_command): Add command for selecting a target
4389 type and calling its open routine. This is used for initiating
4390 communication with a particular target, in a generic way.
4392 * tm-i960.h: Update for modern gdb. Remove semicolons from
4393 various macros. Handle reading struct return convention, and
4394 error-out attempts to return structs with the "return" command.
4395 Be sure gdb doesn't think we know how to call functions in the
4398 * i960-tdep.c: Rename FRAME_CHAIN_VALID and FRAME_FIND_SAVED_REGS
4399 to i960_xxx in lower case.
4400 (arg_address): Circumvent errors due to LOC_ARG_BLOCK
4401 not being defined yet.

4413 (attach_program -> child_open): Use new generic target command.
4414 (wait_for_inferior): Clear saved register values before target_wait,
4415 so target_wait can set some of them if convenient.
4417 * infptrace.c (fetch_inferior_registers, store_inferior_registers):
4418 Return success indicator, not void.
4419 (child_xfer_memory): Avoid fetching initial word if we'll
4420 overwrite it anyway.

4450 * coffread.c (symbol_file_command): Avoid output if from_tty != 1.
4451 Add magic numbers for 960 COFF format.
4453 Fri Nov 30 09:18:20 1990 John Gilmore (gnu at cygnus.com)

4479 Thu Apr 19 09:54:28 PDT 1990
4480 Add 'reset' command.
4482 Wed Apr 18 09:48:07 PDT 1990
4483 After opening remote tty, wait for 1 second to go by without input
4484 from it before trying to talk to NINDY (fixes problems with the
4485 Heurikon HK80/V960E).
4487 Mon Apr 4 16:33:05 PDT 1990
4488 Some output was not being suppressed in 'batch' mode.
4490 Thu Mar 22 15:31:11 PST 1990
4491 Ask user if old symbol table should be deleted when new file is

4529 - moved 960-specific routines from i960-pinsn.c to i960-md.c
4530 - made disassembly interface identical to that in gdmp960.
4534 Wed Nov 28 21:32:48 1990 John Gilmore (gnu at cygint)
4536 * target.h: Allow targets to stack. Add target_has_memory,
4537 _registers, etc. Restructure memory access and "info files"
4538 to walk the target stack.
4539 * exec.c, core.c, inftarg.c, remote.c, remote-vx.c, remote-eb.c,
4540 target.c: Change tables to match target.h.
4541 * inflow.c (child_mourn_inferior): pop child_ops.

4545 * remote-eb.c: New memory regime, new info files.
4546 * remote-vx.c: New memory regime, new info files. Now use
4547 separate targets for VxWorks attachment to machine, and
4548 actually running a process under VxWorks, since one has
4549 stack & execution & regs and the other doesn't.
4550 * remote.c: New memory regime, new info files.
4551 * sparc-xdep.c (fetch_core-registers): New memory regime.
4552 * target.c: New routines and support for stacked targets,
4553 new memory regime, new info files regime.
4556 Generalize section handling for an arbitrary number of sections,
4557 including use of the new BFD (binary file) library.

4559 * exec.c (build_section_table): Iterate all sections and
4560 record what gdb needs to know about them.

4562 (exec_xfer_memory): Use the table.
4563 (exec_files_info): Print the table.
4564 * core.c (core_file_command, core_xfer_memory, core_files_info):

4572 * sparc-xdep.c (fetch_core_registers): Use the .regs info.
4574 * inferior.h (attach_flag): Export.
4575 * infcmd.c (run_command): use new target_create_inferior.
4576 * infrun.c (child_create_inferior): Don't return result.

4585 * core.c (core_file_command): Display the frame where the core
4590 * remote-vx.c (target_command): Merge in target command from
4591 targ-vx.c. A few other cleanups.
4593 * TODO, Projects: Lots more stuff to do...
4595 Fri Nov 23 18:15:38 1990 John Gilmore (gnu at cygint)
4597 Massive changes to wall off the remote-debugging interface
4598 behind a function vector. The port to handle VxWorks targets
4599 is also part of this.
4601 All files: Replace references to renamed functions,
4602 remove references to remote_debugging, remove references to
4603 have_include_file, have_core_file in favor of target_has_stack,
4604 target_has_memory, etc.
4606 * Modularize the breakpoint interface.
4607 breakpoint.h (BREAKPOINT_MAX): New define sets max length of
4608 a breakpoint instruction.
4609 breakpoint.c: struct breakpoint's shadow_contents now sized as
4611 (insert_breakpoints): Vector to target to install breakpoints.
4612 (remove_breakpoints): Vector to target here too.
4613 Remove REMOTE_SA_SPARC kludges and other remote_debugging.
4614 sparc-tdep.c (single_step): Use new breakpoint interface for
4615 the single-step breakpoints.
4616 mem-break.c (memory_insert_breakpoint, memory_remove_breakpoint):
4617 New file, contains routines to insert and remove breakpoints by
4618 reading out the old contents and later replacing them. This is
4619 how ptrace breakpoints work, and many remote systems as well.
4621 * tm-vxworks68.h: New config file, overrides a few things for
4622 Wind River's preferences.
4624 * target.h: New file, for transfer vector used to talk to the
4625 inferior (child, attached, core, exec, remote, etc). All accesses
4626 to the thing being debugged should come through these vectors.
4627 target.c: New file, routines to handle transfer vector.
4628 (various files): Add transfer vectors XXX_ops for the various
4629 targets and pseudo-targets (core files, etc) we support.
4631 * breakpoint.c (bpstat_stop_status): Further explorations of
4632 watchpoints and why things don't work all the time.
4633 (bpstat_alloc): New fn to allocate a bpstat and chain it.
4635 * config.gdb: Only add "source ${srcdir}/.gdbinit" to
4636 the local gdbinit if it doesn't already have it.
4638 * core.c (core_ops): add and install.
4639 Allow core debugging without exec file.
4641 * dbxread.c (free_and_init_header_files): Merge two fns.
4642 (end_symtab): Free named symbol table when a new version comes in.
4643 (read_dbx_symtab): Relocate all kinds of symbols with base
4644 address. First step toward handling different text, data, bss
4646 (add_file_addr_command): Renamed add_file_command.
4647 (add_file_command): Vector to remote handler.
4648 Add "load" as an alias for "add-file" command.
4650 * defs.h: Allow "volatile" to be used in non-ANSI; use it for
4651 non-returning functions.
4653 * exec.c: Add exec_ops, and push it as a target when an exec
4656 * infcmd.c (run_command): Pass executable file name and arg list
4657 separately when starting an inferior. Permit "run" when no exec
4658 file is specified, for VxWorks.
4659 (detach_command): Move to child_detach in inftarg.c.
4661 * inftarg.c: New file. Unix-child-specific routines, and the
4662 child_ops structure.
4664 * inferior.h (registers): Export "registers" as the way for
4665 target dependent register handlers to find gdb's local copy of
4666 the registers. Rename "stop_after_attach" to "stop_soon_quietly"
4667 since it is now used by places that want wait_for_inferior to
4668 handle the grunge but want to see every trap from the inferior.
4670 * inflow.c (create_inferior): Pull out, and merge into infrun.c.
4671 Eliminate remote_debugging hooks in terminal handling.
4673 * infrun.c: Replace start_inferior with child_create_inferior.
4674 Move all the hair of Unix shells and ptrace idiosyncracies into
4675 child_create_inferior, so remote handlers don't have to deal.
4676 Remove running_in_shell. Rename stop_after_attach to
4677 stop_soon_quietly, and use it in a few other places where we want
4678 to just call wait_for_inferior and get control back on the first
4679 trap. trap_expected now never takes a value > 1.
4680 (init_wait_for_inferior): Initialize static vars when a new
4683 main.c (gdbinit): Add new hook for .gdbinit file name, let
4684 it be overridden by config files as GDBINIT_FILENAME.
4685 (DEFAULT_PROMPT): Add new hook for overriding (gdb) prompt.
4686 Both of these are used for VxWorks gdb.
4688 mcheck.c: rename include file "gmalloc.c" to avoid problems
4689 with system include file "malloc.c".
4691 param-no-tm.h: New include file, same as param.h but does not
4692 include the default "tm.h" file. This is used in files where
4693 the target is known, e.g. remote-eb.c or sparc-xdep.c.
4695 param.h: Now just a shell that includes tm.h and param-no-tm.h.
4697 remote-vx.c: New file, VxWorks remote debugging support. Uses
4698 RPC routines that are shared with the target system, in directory
4701 remote.c: Vectorize remote interface.
4703 source.c: Globalize source_path, and make an alias "l" for "list"
4704 since we now have the "load" command.
4706 sparc-xdep.c: Use new param-no-tm.h.
4708 symmisc.c (free_named_symtab): Add new function from Wind River.
4709 However, ifdef it out for now while we think about what it should
4712 tm-sun3.h, xm-sparc.h, xm-sun3.h, xm-symmetry.h: Move
4714 the xm- file, and change its name to CHILD_PREPARE_TO_STORE, since
4715 non-Unix-children handle this with their own code in the target
4718 Makefile.dist: Roll version to 3.92.3. Add vx-share stuff to
4719 source and target lists. Add vx-share to default list of include
4720 directories. Add new files to src and target lists: mem-break,
4721 target, inftarg, remote-eb, remote-vx, targ-vx. Be sure the
4722 ${srcdir} versions of munch and createtags are used.
4724 * valops.c (find_function_addr): Split out of call_function.
4725 (call_function_by_hand): Rename call_function; this function
4726 calls functions in the target by laboriously patching the target
4727 word-by-word with the right stack, args, regs, etc.
4730 Mon Nov 5 17:29:10 1990 John Gilmore (gnu at cygint)
4732 Handle AMD 29000 a bit better.
4734 * remote-eb.c (readchar): Mask received char log to make it readable.
4735 (remote_start): Pass arguments down to executing program.
4736 Make startaddr unsigned.
4737 infrun.c (start_inferior): Accept args, pass them to
4739 infcmd.c (run_command): Pass args down to start_inferior.
4741 * tconfig/am29k-aout, tconfig/am29k-coff: New files specifying
4742 the target object file format.
4743 tm-29k.h: Pay heed to COFF_ENCAPSULATE.
4745 * am29k-pinsn.c (print_insn): Print 0x on hex numbers in disassembly.
4746 am29k-tdep.c (examine_prologue): Better checking of function prefixes.
4748 Sun Oct 7 18:20:45 1990 John Gilmore (gnu at cygint)
4750 * Makefile.dist (VERSION): Roll version to 3.91.9 and freeze.
4751 * TODO: We did a few things, we have more to do though.

4759 (sparc_frame_find_saved_regs): Simplify and fix what we find.
4760 (sparc_push_dummy_frame): Simplify and fix what we push.
4761 (sparc_pop_frame): Slightly more hair here, deciding whether
4762 we are restoring a saved PC or returning to a return address in %i7.
4763 * sparc-xdep.c (read_inferior_registers): Debug if valid reg is read.
4765 * utils.c (xmalloc, xrealloc): Return type depends on __STDC__.
4766 * symtab.h (xmalloc): ditto, for obstack_chunk_alloc.
4767 * obstack.h (chunkfun): ditto.
4768 * defs.h (xmalloc, xrealloc): ditto
4770 * utils.c (quit): Grab the terminal from the child if necessary.
4772 * inflow.c (term_status_command): Rename to term_info, change
4775 * sparc-pinsn.c (print_insn): Disassembly prefers real instructions.
4776 (is_delayed_branch): Speed up.
4777 * sparc-opcode.h: Add ALIAS bit to aliases. Fix up opcode tables.
4778 Still missing some float ops, and needs testing.
4780 * Support for input and output radixes other than base 10
4781 * defs.h (input_radix, output_radix): Declare.
4782 * expread.y (yyparse, parse_number): Handle changes of input
4783 radix, and ambiguous names-or-numbers in radixes >10.
4784 * printcmd.c (print_scalar_formatted): Print formatted hex
4785 numbers in varying column widths.
4786 * valprint.c (val_print): Use output_format to print scalar ints.
4787 (set_input_radix, set_output_radix, set_radix): Create.
4788 (set_output_radix): Set output_format from output_radix.
4789 (_initialize_valprint): add `set radix' but leave the others off.
4791 * main.c (execute_command): Let stupid questions be turned off.
4792 (_initialize_main): Handle "set stupidity", etc.
4794 * main.c, inflow.c, inferior.h, frame.h, command.c, defs.h,
4795 sparc-pinsn.c, sparc-xdep.c, value.h, valops.c, values.c: Lint.
4797 Tue Oct 2 11:20:02 1990 John Gilmore (gnu at cygint)
4799 * TODO, Makefile.dist, ChangeLog: Freeze for 3.91.8 release.
4800 bfd stuff is still screwed up, but with some manual work, it
4803 * breakpoint.c (bpstat_do_actions): Start over if a command
4804 proceeds the inferior, since the inferior will have stopped and
4805 will need to have its new stop-actions taken care of.
4807 * dbxread.c (read_struct_type): Expression gives Sun3 4.0.3
4808 compiler fits, simplify it.
4810 * gdb.texinfo (directory command): Doc new dir command.
4811 source.c (directory_command): "dir" now puts things on the front
4812 of the path, moves dups up front, and handles multiple names
4813 on the command line, inserting each one in order. It also
4814 blows away cached line and full_filename info.
4816 * stack.c (backtrace_command): Skip "more stack frames follow"
4819 * Change #ifndef HAVE_VPRINTF to #define MISSING_VPRINTF in
4820 xm-convex.h, xm-hp300bsd.h, xm-isi.h, xm-merlin.h, xm-news.h,
4821 xm-np1.h, xm-pn.h, xm-pyr.h, xm-symmetry.h, xm-umax.h, xm-vax.h.
4822 The only odd one was Gould NP1, which had defined vprintf to
4825 * Merge Ted Goldstein <tedg@Eng.sun.com>'s changes for epoch.
4826 printcmd.c (print_command_1): Pass 'inspect' flag down as a global
4827 variable, inspect_it.
4828 valprint.c (print_string, val_print): Use the global inspect_it
4829 to indicate whether to print in Epoch style or normal style.
4831 Mon Oct 1 23:55:26 1990 John Gilmore (gnu at cygint)
4833 * printcmd.c (call_command): add an alias for the "print" command
4834 which runs expressions and doesn't print the result if void.
4835 (print_command_1): implement it.
4837 * command.c: Remove #if 0'd code. Initialize all the fields
4838 in add_cmd (). Rename do_nothing_command to
4839 not_just_help_class_command, and make it externally visible.
4840 command.h: add user_commands to struct.
4841 * main.c (define_command): Don't overload c->function with a char
4842 string as well as a function pointer.
4844 * eval.c (evaluate_subexp): Reinstall tiemann changes to
4845 calling convention of value_struct_elt () that got dropped in
4848 * tm-sparc.h (FRAME_FIND_SAVED_REGS): move to sparc-xdep.c.
4849 sparc-tdep.c (sparc_frame_find_saved_regs): ditto.
4851 * tm-sparc.h (POP_FRAME): replace some constants with defines.
4853 * sparc-xdep.c (store_inferior_registers): defer stores to regs
4854 until a good time (e.g. when we are about to run the child),
4855 saving ptrace calls.
4856 * infrun.c (proceed): handle DO_DEFERRED_STORES.
4857 * tm-sparc.h: define DO_DEFERRED_STORES.
4859 * sparc-xdep.c (store_inferior_registers): when storing float
4860 registers, don't store stack regs too. When storing the SP,
4861 however, DO store the stack regs too. This fixes a bug in which
4862 the dummy frame is not recognized when a call_function finishes,
4863 because its frame pointer (in the stack regs) was never
4865 (read_inferior_registers): Mark WIM and TBR and FPS and CPS valid
4866 even though we don't know how to read them from an inferior.
4867 valops.c (call_function): Comment about storing SP.
4869 * infrun.c (save_inferior_status): Save away the original bpstat
4870 chain so it can be restored later. Install the copied version for
4871 use by whoever saved the status. It will be blow away by
4872 restore_inferior_status, and the original chain restored. This is
4873 important for people who have pointers into the original.
4875 * breakpoint.c, command.h, copying.awk, dbxread.c, defs.h,
4876 findvar.c, frame.h, obstack.h, obstack.c, inflow.c, value.h,
4877 main.c, printcmd.c, sparc-tdep.c, symtab.c, valprint.c: lint
4880 Fri Sep 28 20:32:46 1990 John Gilmore (gnu at cygnus.com)
4882 * Makefile.dist: Roll version to 3.91.8. Add bfd.h and bfdconfig.h
4883 temporarily to the makefile. Add am29k-opcode.h and WHATS.NEW.
4884 Add stuff.c and kdb-start.c to the OTHERS list for tar files.
4886 Fri Sep 28 19:12:12 1990 John Gilmore (gnu at cygint)
4888 * Merge Mike Tiemann's multiple inheritance changes from Sun.
4889 Store the baseclasses in a type struct starting from array element
4890 0 rather than from the unusual array element 1.
4892 dbxread.c: the above.
4893 (virtual_context): Add
4894 Read new debug information about which virtual function table
4895 a virtual function is from, and store it in fn_field.fcontext.
4897 symtab.h: Add fcontextt. Fix baseclass indices. Typo in
4898 TYPE_FN_FIELD_STATIC_P.
4900 symtab.c: the above.
4901 valops.c: the above. Handle pointer casts of object *'s.
4902 (search_struct_method): Add.
4903 (value_struct_elt): First arg is now a pointer to a value, and is
4906 valprint.c: the above.
4907 values.c (value_virtual_fn_field): Add type arg. Handle
4908 offsetting to the proper object when calling virtual fns.
4910 (baseclass_addr): Add valuep arg.
4912 * README: Document the current state of BFD config (missing).
4913 * TODO, ChangeLog, Makefile.dist: Roll version.
4914 * WHATS.NEW: Add summary of changes since 3.5.
4916 Thu Sep 27 16:23:12 1990 John Gilmore (gnu at cygint)
4918 * dbxread.c (read_struct_type): Clear bit vectors whenever
4920 symtab.c (B_CLRALL): define.
4922 * tm-sparc.h (STORE_RETURN_VALUE): Avoid clobbering types by
4923 using == rather than =. Huh... This fixes the dreaded problem
4924 wherein builtin_type_int becomes TYPE_CODE_FLT.
4926 * core.c (info_files): Show the inferior pid.
4928 * config.gdb: Avoid putting "dir" command into .gdbinit. GDB
4929 already knows how to look in the source directory.
4931 * Remove psymtab hair from many places. Remove duplicated code
4932 for searching symbol tables. Hide psymtabs from most places.
4933 Make it fast to get from a psymtab to its symtab.
4935 blockframe.c (blockvector_for_pc): Remove psymtab hair.
4936 coffread.c (psymtab_to_symtab): Rename to psymtab_to_symtab2.
4937 mipsread.c (psymtab_to_symtab): Rename to psymtab_to_symtab2.
4938 dbxread.c: export psymtab_to_symtab, make it work if called N times.
4939 (psymtab_to_symtab): Rename to psymtab_to_symtab2. Initialize
4940 new symtab completely. New psymtabs get symtab pointer
4941 initialized to zero. Remove MI warning printf.
4942 symtab.h: Comments. Add psymtab to symtab pointer.
4943 (PSYMTAB_TO_SYMTAB): New macro.
4944 symtab.c: use PSYMTAB_TO_SYMTAB. Add psymtab_to_symtab and export it.
4945 source.c: use PSYMTAB_TO_SYMTAB. Remove symtab version and
4947 stack.c (backtrace_command): Avoid pre-pass to read symbols, if
4949 (print_frame_info): Avoid special-casing symbols that have not yet
4952 * source.c (open_source_file): Quick path if we have already
4953 located the source file by its full name.
4955 * symtab.c (lookup_symbol): Use find_pc_symtab rather than
4956 find_pc_psymtab. When a name is found in the misc function
4957 vector, search the symbol table for its mangled name, not the
4958 name that the user typed.
4960 * bfd.h: Fix missing comment terminators, make #endifs match.
4962 * valarith.c (value_less): Handle unsigned int comparisons.
4963 Add FIXME about pointer compares, which assume host and target
4964 pointers are the same.
4966 * command.c (do_nothing_command): lint
4967 dbxread.c: lint. Remove sort_syms. Document C++ visibility info,
4968 fix comments on debug symbol format for visibility. Actually set
4969 visibility of symbols.
4970 main.c (echo_command): lint; use <readline/history.h>.
4971 tm-sparc.h (FRAME_FIND_SAVED_REGS): lint
4972 obstack.h (_obstack_blank): Rearrange pointer math to avoid
4973 pointing past end of allocated memory; saber complains.
4974 obstack.h: Declare the external functions that we use.
4975 valarith.h: use <string.h>
4976 solib.c (solib_add): lint.
4978 Fri Sep 21 17:05:19 1990 John Gilmore (gnu at cygint)
4980 * main.c (initialize_main): Default info_verbose to off, now that
4981 symbol reading is fast.
4982 (quit_command): Avoid clobbering exec_bfd while quitting.
4984 * Initial BFD (binary file diddling library) merger:
4985 coffread.c: Change AOUTHDR to struct exe_hdr.
4987 core.c: initialize initialized data at compile time.
4988 (core_file_command): Move from coredep.c, convert to bfd.
4989 (xfer_core_file): Convert to bfd.
4990 exec.c (exec_file_command): use bfd routines.
4992 mips-tdep.c: Remove exec_file_command and friends.
4995 * coredep.c: (fetch_core_registers) Convert core_file_command to
4996 fetch_core_registers.
4997 mips-xdep.c, sparc-xdep.c, sun3-xdep.c: ditto.
4999 * utils.c: (error): Bogus crap, FIXME, to print bfd errors.
5000 (my_bfd_read): More bogosity, which I don't think we call.
5001 (program_name): Remove this atrocity asap!
5003 Wed Sep 19 13:36:41 1990 John Gilmore (gnu at cygint)
5006 values.c: allocate_repeat_value was not clearing the
5007 optimized_out field.
5008 (value_static_field): minor stylistic fix (wrong macro was used).
5009 valops.c (value_struct_elt_for_address): didn't work for C++
5012 * signame.c (_initialize_signame): Initialize signal names once.
5014 * breakpoint.h, command.c, copying.awk, defs.h, environ.c,
5015 exec.c, frame.h, infcmd.c, inferior.h, main.c, munch, sun3-xdep.c,
5016 symtab.h, tm-29k.h, valprint.c, value.h, values.c: Lint.
5018 * remote-eb.c: Support user-settable baud rates on the serial port.
5020 * tm-sun3.h (PREPARE_TO_STORE): fix typo.
5022 Fri Sep 14 13:28:29 1990 John Gilmore (gnu at cygint)
5024 * tconfig/sun3os4: Remove warning about native assembler,
5025 since it also occurs in the xconfig file.
5027 * findvar.c (registers): Allocate some slop after `registers'
5028 to prevent stray accesses from trashing the next variable.
5030 * tm-68k.h (REGISTER_BYTES): Allocate the right number of bytes
5031 on the sun-3, by changing the #ifdef from `sun3' (which is not
5032 defined by cc) to `sun'. Symptom was trashed builtin_type_XXX
5033 vars, which happened to follow `registers' in the executable.
5035 * readline/history.c (history_search): Heed gcc-2's advice
5036 and parenthesize && inside ||).
5038 * am29k-opcode.h, am29k-pinsn.c, am29k-tdep.c, remote-eb.c,
5039 tm-29k.c: Insert FSF copyright headers.
5041 * remote-eb.c: Better comments.
5043 * Makefile.dist: Update to 3.91.6.
5044 * TODO: note PREPARE_TO_STORE problem.
5046 Thu Sep 13 09:52:33 1990 Jim Kingdon (kingdon at cygint)
5048 * stack.c (frame_info): Only use FRAME_FIND_SAVED_REGS if defined.
5050 * remote.c: Wrap the whole file in #if !defined (SPECIAL_REMOTE).
5052 * infrun.c (wait_for_inferior, at end): Don't set up
5053 prev_* if the inferior no longer exists.
5055 * inferior.h (CALL_DUMMY_LOCATION): New macro, to replace
5056 CANNOT_EXECUTE_STACK.
5057 valops.c (call_function): Use it.
5059 * tm-convex.h: Add CALL_DUMMY_LENGTH for use by PC_IN_CALL_DUMMY.
5061 * inferior.h (PC_IN_CALL_DUMMY): New macro.
5062 infrun.c (wait_for_inferior, 2 places): Use it.
5064 * values.c (value_being_returned): Only use
5065 EXTRACT_STRUCT_VALUE_ADDRESS if defined.
5067 * Move PREPARE_TO_STORE from xm-sun3.h to tm-sun3.h to do the
5068 right thing for remote-eb.c.
5070 * sun3-xdep.c: Remove extraneous call to remote_store_registers.
5071 * sun386-xdep.c, hp300hpux-xdep.c, sparc-xdep.c: Ditto.
5073 * blockframe.c: Put get_frame_saved_regs inside #if !defined
5074 (FRAME_FIND_SAVED_REGS).
5076 * findvar.c ({fetch,store}_registers): Check for
5077 REMOTE_{FETCH_STORE}_REGISTER macro.
5079 * findvar.c (get_saved_register): Add argument lval and
5080 change meaning of argument addr.
5081 findvar.c: Change calls to get_saved_register to reflect
5082 new calling convention.
5083 valops.c (value_assign): Use get_saved_register instead of
5084 find_saved_register.
5086 Sun Sep 2 12:40:20 1990 Jim Kingdon (kingdon at cygint.cygnus.com)
5088 * coffread.c (read_one_sym): Make temp_aux an AUXENT, not
5089 an (uninitialized) pointer to one. Use "&" when passing it
5092 Fri Aug 31 22:57:54 1990 Jim Kingdon (kingdon at cygint.cygnus.com)
5094 * coffread.c (getfilename): Use DGUX x_offset and x_name if
5097 * coffread.c (symbol_file_command): Put semicolon after
5099 Put safe_to_init_tdesc_context in #if defined (TDESC).
5100 Put #ifdef TDESCs in 1st column for non-ANSI cpp's.
5101 coffread.c: #include <sys/stat.h>.
5102 (read_coff_symtab): Typo: in_source_files -> in_source_file.
5103 Add missing ')' in check for "lc%" and friends. Remove
5105 Declare read_one_sym() at top of file.
5106 (read_file_hdr): Put in extra #ifdefs so MC68MAGIC and
5107 MC68WRMAGIC can have the same value without causing a duplicate
5110 Thu Sep 13 15:55:36 1990 John Gilmore (gnu at cygint)
5112 * Allow a Makefile to be built without building the
5113 tm and xm file links that screw up builds in subdirectories.
5114 This is done with `config.gdb none', then you can do things
5115 like `make gdb.tar.Z'.
5116 * tconfig/none: Config file for no target system
5117 * xconfig/none: Config file for no host system
5118 * config.gdb: If no TM or XM files are called out by the
5119 host or target file, don't make links for them.
5121 * cplus-dem.c: Add documentation.
5123 * dbxread.c (read_ofile_symtab): Turn a fatal error into a
5124 simple error, so the user's gdb doesn't crash due to some object
5125 file problem (e.g. somebody is rebuilding the file out from under
5128 * printcmd.c (print_address_symbolic): demangle the symbol.
5130 * Makefile.dist (OTHERS): Remove tdesc-lib because it has
5131 Motorola copyrights in it. Make "make gdb.tar.Z" work.
5132 (alldeps.mak): sort and uniq all results from this; duplicates
5133 hose gdb.tar.Z link building. Remove RCS files from
5134 tconfig and xconfig. Add config files for sun386. Add
5135 a few odd files to OTHERS and HFILES.
5137 Mon Sep 10 21:20:24 1990 John Gilmore (gnu at cygint)
5139 * Makefile.dist: Pull solib.c to tconfig/sun?os4.
5140 Roll version number to 3.91.5. Make lint work in bindir.
5142 * README: Document cross-debugging and new file structure.
5144 * blockframe.c: Lint. Include "value.h" to declare read_register.
5145 (find_pc_partial_function): remove duplicate line.
5147 * command.h: Lint. Declare error_no_arg and dont_repeat.
5149 * tm-news.h: Remove inadvertently duplicated stuff.
5151 * mipsread.c: Remove cache_pc_function stuff, now done cleanly.
5152 Clean up usage of misc_function_type. Declare some CORE_ADDRs.
5154 * config.gdb: Allow `config.gdb host target' form. Clean
5155 up previous change that printed bogus messages when you just said
5158 * core.c: #include "command.h" for lint.
5161 * main.c: Remove some casts of enums. Lint.
5168 * printcmd.c (initialize_printcmd): Fix thinko in inspect cmd.
5170 * sparc-tdep.c (isannulled): Take instruction as parameter, don't
5171 read it from memory. This will allow us to save ptrace calls
5172 eventually. Changed caller single_step too.
5174 * sparc-xdep.c (fetch_inferior_registers): Avoid reading regs
5175 that we aren't going to use, saving many ptrace calls, especially
5176 when watchpointing or single stepping. Use some #define's for
5178 (store_inferior_registers): Ditto.
5179 (core_file_command): Use some #define's for constants.
5181 * tm-sparc.h: Add #define's for some register numbers, so we
5182 can eliminate the use of random constants in sparc-xdep.c.
5184 * stack.c (frame_command, print_frame_info, up_command,
5185 down_command) Remove frame_changed, since it
5186 causes a bug and doesn't seem to do anything useful. In some
5187 places it was used as a flag, in others as a stack level (?).
5189 * utils.c: Use MISSING_VPRINTF rather than HAVE_VPRINTF, so the
5190 default is to use the portable (vprintf) version rather than the
5192 * xm-news.h (MISSING_VPRINTF): Add.
5194 * valprint.c (val_print): Demangle fancy vtbl printouts. Lint.
5196 Sat Sep 8 00:24:12 1990 John Gilmore (gnu at cygint)
5198 * Remove stuff that forces -Bstatic linking of gdb, and warnings
5199 about linking debugged programs -Bstatic in the sun?os4 config
5200 files in tconfig and xconfig subdirectories.
5202 * main.c (main): Remove unreached exit(0) now that we exit
5205 * Create TODO file for online bug list. There are too many
5206 "little" bugs to keep track of on paper.
5208 * Change Projects file to refer to bug-gdb@cygnus.com
5209 rather than kingdon@ai.
5211 Fri Sep 7 23:35:15 1990 John Gilmore (gnu at cygint)
5213 * Makefile.dist (VERSION): 3.91.4 now.
5215 * symtab.c (init_misc_bunches): Rename from init_misc_functions.
5216 (condense_misc_bunches): Add sanity check that misc_count is
5217 the same as the number of symbols in the bunch.
5219 * coffread.c: rename init_misc_bunches. Pass an argument
5220 to condense_misc_bunches (a zero).
5222 * dbxread.c (partial_symbol_file_read): Call init_misc_bunches
5223 every time we are called; don't rely on our caller to do it.
5224 (add_file): Remove call to init_misc_bunches.
5226 * mipsread.c: Only warn, don't error, if unknown symbol types.
5227 This keeps an old gdb from falling on its face if it sees newly
5228 extended symbol info. Rename init_misc_bunches.
5230 Fri Sep 7 22:58:15 1990 John Gilmore (gnu at cygint)
5232 * Merge in changes from Per Bothner for DECstations and other
5233 MIPS stuff. The rest is Bothner speaking:
5235 The next message is a merger of Alessando Forin's mips port with
5236 mine. I've tried to use my good if biased judgment to get
5237 the best of both. It *does* need testing.
5239 Some of the changes are general, *not* mips-specific.
5242 Didn't believe in little-endian bit order.
5243 There are still inconsistencies about whether flags
5244 like BITS_BIG_ENDIAN are integer (#if ...) or
5245 boolean (#ifdef ...). I tried to paper over them.
5247 dbxread.c,coffread.c,mipsread.c,symtab.c,symtab.h:
5248 Moved some misc_function code that was common to
5249 {dbx,coff,mips}read.c to symtab.c.
5250 In the process, I think I cleaned things up a bit.
5251 At the same time, moved obsavestring and obconcat to symtab.c.
5254 Removed obsolete condense_addl_misc_bunches (use
5255 condense_misc_bunches(1) instead).
5258 Needed to include <sys/dir>, at least on DECstations.
5260 valops.c, mips-tdep.c, tm-mips.h:
5261 Added PUSH_ARGUMENTS macro to support funny argument-pushing
5262 conventions (when STACK_ALIGN is insufficient).
5263 Needed on mips, where doubles need 8-byte alignment,
5264 but ints only need 4.
5267 Removed cruft that was not being used.
5268 Merged in many fixes (most from Frank Yellin, fy@lucid.com).
5271 Print $ before register-names (I think that makes things a little
5273 Never print two instructions, even if one delays.
5274 Removed hex-disassemble set_cmd. (This is not mips-specific,
5275 so I think the argument is whether it is generally worthwhile or not.
5276 I'm inclined to think not, given how easy it is to
5277 convert between radixes in gdb.)
5280 This is basically Alessando's code.
5281 It doesn't use obstacks; I changed it to use obstacks
5282 in a few minor places where using malloc causes a
5283 memory leak. (Probably, more places could/should be changed.)
5284 I added record_misc_function where it was missing.
5285 In symbol_file_command and add_file_command, I tried
5286 to make the code consistent with more recent versions.
5287 Minor sylistic changes in parse_procedure.
5288 Make a .gdbinfo. psuedo-symbol point back to the real
5289 procedure symbol (using the isym field).
5292 This is basically from my port, but with a lot of details
5293 and a number of routines merged in from Alessando's version.
5294 I basically used my code "raw" backtrace (use heuristics
5295 from the actual code, rather than symbol table info) - though
5296 the idea is Alessandro's. I feel my code is a little cleaner
5297 here, particularly in being a little more flexible, such as being
5298 able to handle gcc-produced code (which it now can).
5299 It also doesn't do frame caching (which is not useful
5300 more recent gdb versions).
5301 I also used my code for push_/pop_dummy, more or less.
5302 I tried to incorporate AF's code for testing sigtramp
5303 while backtracing; I probably got it wrong.
5304 Added mips_print_register, which tries to scrunch as much
5305 information as possible on a screen...
5306 Removed the skip-prologue set_cmd. As with hex-disassemble (see
5307 under mips-pinsn.c), I don't see anything mips-specific here,
5308 and I don't see it being all that useful anyway.
5311 Added a $fp psuedo-reg distinct from $fp (nice for gcc).
5312 Use more register names (rather than hard-cases numbers).
5314 Thu Sep 6 18:33:15 1990 John Gilmore (gnu at cygint)
5316 * Hack up 3.90.11 changes:
5318 * Makefile.dist (depend): parameterize $(GCC).
5319 Add solib.c and solib.o.
5320 (readline): Fix vpath for both absolute or relative SRCDIR.
5322 * blockframe.c: Fix from Schaefer@asc.slb.com for shared libs.
5323 Also, let the part I didn't understand at least compile so
5324 I can test the rest. FIXME.
5326 * dbxread.c: Fix thinko using strcmp.
5327 (init_psymbol_list): declare static.
5328 (partial_symbol_file_open): Comment cleanups better, avoid
5329 cleaning up the string table since the caller will do that.
5330 Move the stat for mod time into symbol_file_command, temporarily.
5331 (There should be a mod time for each symbol file, eventually,
5332 to control its rereading. FIXME.)
5334 * infptrace.c (PT_WRITE_D): use same value as PT_WRITE_I for
5335 SunOS, which gives error for shared libs otherwise. (From
5336 Schaefer, probably FIXME needs work for portability.)
5338 * solib.c: Move #include "param.h" to work.
5339 Lowercase all the Uppercase Letters In the Messages.
5340 (find_solib): Clean up inferior_so_name for debug printouts.
5341 Allow no argument, to mean all shared libraries.
5343 * symmisc.c: include param.h to get CLEAR_SOLIB.
5345 Wed Sep 5 18:00:08 1990 John Gilmore (gnu at cygint)
5347 * Merge in Kingdon's changes from FSF: the diffs from 3.90.9

5391 Take code which is shared between symbol_file_command and
5392 add_file_command and put it into partial_symbol_file_{open,read}.
5393 Split add_file_command into add_file_command and add_file.
5394 Make psymtab_to_symtab read in the string table if the file
5396 Two new parameters to read_dbx_symtab and start_psymtab.

5443 consistency with POSIX.
5445 * breakpoint.c (bpstat_stop_status): Disable watchpoint

5448 Tue Sep 4 11:46:46 1990 John Gilmore (gnu at cygint)
5450 * Makefile.dist: Bump version to 3.91.3.
5452 * Clean up handling of breakpoint commands (somewhat).
5453 Prompted by Tiemann bug report "cont 10" doesn't work any more.
5455 inferior.h: Add breakpoint_proceeded to inferior status struct
5456 and globals; save it and restore it.
5457 (clear_breakpoint_commands): Cleanup, remove old #define.
5459 infrun.c (clear_proceed_status): Set breakpoint_proceeded.
5460 (save_inferior_status, restore_inferior_status): handle it also.
5461 (proceed): Remove earlier code that set breakpoint_proceeded.
5462 It is now set only in clear_proceed_status.
5463 (clear_proceed_status): Cleanup, use bpstat_clear rather
5464 than clear_breakpoint_commands. No callers need the stop_bpstat
5465 between clear_proceed_status and proceed.
5467 infcmd.c: Add breakpoint_proceeded definition and comment.
5468 (cont_command, jump_command, signal_command): Move call to
5469 clear_proceed_status right next to call to proceed.
5471 breakpoint.c (bpstat_do_actions): Avoid clobbering our
5472 caller's argument while running down the chain of breakpoints.
5473 Use new variable "breakpoint_proceeded" to determine when
5474 a command that it executes moves the inferior past the
5476 (bpstat_clear): Handle NULL argument.
5477 (bpstat_clear_actions): Avoid useless call to
5478 breakpoint_auto_delete.
5479 (delete_breakpoint): Clean up bpstat's that are pointing to
5480 the deleted breakpoint from the stop_bpstat chain.
5481 (breakpoint_auto_delete): Simplify.
5483 * Clean up handling of EOF, error on stdin, etc. This was
5484 prompted by a network problem that caused gdb to go into an
5485 infinite loop filling up its malloc'd memory.
5487 main.c (return_to_top_level): Cleanup: call bpstat_clear_actions,
5488 not clear_breakpoints_commands, which is now gone.
5489 (main): If command_loop returns (e.g. from EOF on stdin), do
5490 a quit_command (looping back to command_loop if quit_command
5491 doesn't really quit).
5492 (command_loop): check result from command_line_input and
5493 exit if it returns NULL, rather than passing the NULL to
5495 (gdb_readline): Free malloc'd result space before returning
5498 * utils.c (query): Handle C-d to mean "yes", just as if the
5499 input was not a terminal. Also avoid infinite loop if EOF
5500 occurs in mid-input-line before newline. This allows
5501 query to be used at EOF on stdin with reasonable results.
5503 * infrun.c (proceed): Set breakpoint_proceeded.
5505 * values.c (value_as_long): Avoid infinite recursion for enums.
5506 (_initialize_values): Fix typo in help msg (kingdon).
5508 * Makefile.dist (RL_LIB): Use RL_LIB_DEP for dependencies,
5509 RL_LIB for linking. This allows -lreadline for linking
5510 and nothing for dependencies, once readline is a real library.
5512 * config.gdb: Jim Kingdon: give useful error message if the
5513 host or target type is not recognized.
5515 * defs.h (alloca): SPARC <alloca.h> does not declare alloca,
5516 it just defines it. Dumb, but deal with it.
5518 * Jim Kingdon suggests:
5519 in xconfig/sun3os4, CFLAGS should be XM_CFLAGS.
5521 Wed Aug 29 18:03:27 1990 John Gilmore (gnu at cygint)
5523 * Makefile.dist (VERSION): Bump version # to 3.91.2.
5525 * Clean up Bothner's changes.
5527 * blockframe.c (clear_pc_function_cache): New function.
5528 * blockframe.c: remake cache_pc_function_* static.
5529 * dbxread.c (symbol_file_command): remove references to
5530 cache_pc_function_* variables.
5531 * dbxread.c (read_struct_type): Use VOFFSET_STATIC.
5532 * printcmd.c: Avoid kludging a global variable (addressprint)
5533 to avoid printing the address of a string twice. Instead,
5534 pass the format letter 's' down low enough that it can be seen
5535 to avoid this problem.
5536 (print_formatted): Pass format arg to value_print.
5537 (restore_addressprint): Remove function.
5538 (do_examine): Avoid hacking addressprint, cleanups and such.
5539 (print_frame_args): Add a comment to a Bothner change.
5540 * symtab.h: define VOFFSET_STATIC and use it instead of "-1".
5541 * symmisc.c (free_all_symtabs): Call clear_pc_function_cache
5542 to wipe out the values cached in blockframe.c.
5543 * symtab.c (find_method): Add comment saying how big you must
5544 allocate to be "big enough". Per being terse again.
5545 * valprint.c (val_print): Handle format letter "s" to print
5546 strings without addresses. Add comment to vtbl printing code
5547 which casts with wild abandon. Rearrange reference-printing
5549 @0xaddr: value (print w/addressprint)
5550 value (print w/~addressprint)
5551 @0xaddr (parameter lists w/addressprint)
5552 or nothing (parameter lists w/o addressprint)
5554 Tue Aug 28 10:47:18 1990 John Gilmore (gnu at cygint)
5556 * Merge more changes from Per Bothner:
5558 Gdb's handling of TYPE_CODE_REF was so counter-C++ (and otherwise
5559 annoying) that I tried to improve it. Here are my suggestions.
5561 These patches all attempt to handle TYPE_CODE_REF (as in C++) better.
5564 Do automatic de-reference when taking the address of a reference.
5566 Don't deref_ref when printing parameter lists.
5568 More attempts at treating refernences properly.
5570 In val_print, if deref_ref==0, don't print dangling " = ".
5572 Add COERCE_REF macro, which de-references an REF.
5574 * Merge changes from Per Bothner:
5576 * Fixed (Sony news)-specific configuration problems.
5577 * Fixed other problems with using vanilla pcc and libc (enum problems;
5578 assumption that vsprintf exists).
5579 * Some major speed-ups (finc_pc_partial_function now caches a match;
5580 parsing avoids duplicate symbol_lookup calls).
5581 * Changed handling of baseclasses (no longer use baseclasses field
5582 of struct type, use the first n_baseclasses fields instead).
5583 * Various minor changes/fixes, most C++-related.
5586 Cache the most previous match from find_pc_partial_function.
5587 (Save both low and high ends of matching function's pc range.)
5588 This speeds up the loop of infrun.c:wait_for_inferior quite
5589 a bit, and makes step/next commands much zippier.
5591 Added an enum->int cast (otherwise, some compilers barf).
5593 No longer set baseclass offset to 0, since multiple
5594 inheritance now mostly works.
5595 Added a number of casts, to shut up compiler warnings
5596 (after stabs where made enums, not ints).
5597 When discarding a symbol table (in symbol_file_command),
5598 must clear the cache introduced in blockframe.c.
5599 Don't convert $vtbl_ptr_type to vtbl any more.
5600 Get rid of TYPE_BASECLASEES and baseclass_vec (see also symtab.h).
5601 Mask off sign bit emitted by g++ for virtual table offset.
5602 Set voffset to -1 (not 1) for static member functions.
5604 Changed parsing/lexing of names to avoid doing symbol lookup twice
5605 (once when lexing to determine symbol class, once for real).
5606 Now only call symbol_lookup once. Fields of 'this' win especially big.
5608 Subpress printing addr twice in the case of 'x/s addr'.
5610 lookup_basetype_type is no longer used.
5611 Add find_methods as recursive helper function to decode_line_1.
5612 This allows multiple inheritance to work.
5613 Also, once one or more matches has been found, do not look in
5614 base-classes. (Baseclass methods would be overridden, anyway.)
5616 Removed baseclasses array in struct type.
5617 Instead of using baseclasses[i], use fields[i-1].
5618 Added virtual_field_bits[i] to indicate if the i'th baseclass is virtual.
5619 Changed sign convention of voffset (previous was inconsistent).
5621 Some macros (CALL_DUMMY and relatives) were missing. Put them back.
5623 Used to assume existence of vsprintf. Re-written to not need it
5624 if HAVE_VPRINTF is undefined.
5626 typecmp was too pessimistic. Made it less so.
5628 Don't print space after address.
5629 If vtable points to a misc symbol (with 0 offset), print it,
5630 since that indicates the actual class of the object.
5631 Changed ype_print_derivation_info to use new inheritance
5632 scheme (without baseclasses vector).
5634 In value_primitive_field, fixed some bugs left over from previous set of fixes.
5635 Also, changes needed because TYPE_BASECLASSES were removed.
5637 REGISTER_U_ADDR didn't work for PC. Rewrote to use an array.
5639 Tue Aug 21 20:08:54 1990 John Gilmore (gnu at cygint)
5642 If there is no path set, and the symbols don't indicate what directory
5643 a file was compiled in, look in the current directory. But either
5644 a path or a known compilation directory will prevent this.
5647 Three independent bug fixes:
5648 * Remove the #if 0 block that breaks some stuff.
5649 * SunOS 4.1 fixed the promoted-parameter-wrong-addr bug in Sun C;
5650 adapt gdb to either SunOS 4.0.* or 4.1.
5651 * MAX_OF_TYPE and MIN_OF_TYPE thinko. By tedg@sun, I think.
5654 Instantiate the class T when looking for methods in it. (Tiemann@sun)
5657 (type_print) Demangle the name being printed.
5658 (type_print_base) Handle botched demangling without coredump (tiemann).
5661 (check_stub_method): Document routine.
5662 (tiemann) fix bug for no-arg functions
5663 Avoid clobbering beyond end of malloc'd storage.
5664 Terminate the argument list properly.
5666 Sat Aug 18 01:29:59 1990 Per Bothner (bothner@cs.wisc.edu)
5668 * Changes merged by John Gilmore:
5671 In breakpoint_1, use new print_address_symbolic instead
5672 of find_pc_partial_function. (This forces use of assembler-level
5673 addresses, and avoids misleading non-mangled source-level names.)
5675 Generalize ansi argument such that -1 means skip arglist totally.
5676 Removed global variable print_ansi_qualifiers (which made
5677 code non-reentrant), in favor of extra explicit arguments
5678 to internal routines.
5680 Add new helper function print_address_symbolic.
5681 Use find_pc_misc_function instead of find_pc_partial_function
5682 (since we want assembler-level symbols here).
5684 Print unknown function as just "f (...)", not "f (...) (...)".
5685 Use new fputs_demangled explicitly.
5687 Fixed a typing violation (problem: value.h cannot be imported
5688 without renaming many variable in this file).
5689 lookup_symbol: If no matching misc_func, look for a C++-mangled name.
5690 decode_line_1: Moved forward some never-reached code.
5691 Made decode_line_2 skip function prologues correctly.
5693 fputs_filtered should not demangle by default.
5694 Add new fputs_demangled to demangle on demand..
5696 Change value_struct_elt to use value_primitive_field (using recursive
5697 utility function search_struct_field). This allows foo.bar to work
5698 for multiple inheritance (so far only for data fields).
5699 Change check_field in the same way (recursive helper function
5700 to support multiple inheritance).
5701 (Note: there are more of these problems that I haven't fixed.
5702 Any code that says TYPE_BASECLASS (t, 1) is probably wrong.)
5703 value_of_this: 'this' symbol name is now just "this", note "$this".
5705 Don't print static members.
5706 Avoid printing "members of <type>" if there are none.
5707 Simplified type_print_derivation_info by merging duplicate code.
5708 Remove useless blank lines in type_print_base (ptype command).
5710 Added declaration of new routine value_primitive_field.
5712 Added value_primitive_field which is generalized version of
5713 value_field that can handle multiple inheritance (non-zero offsets etc).
5714 Re-implemented value_field to call value_primitive_field.
5716 Fri Aug 17 23:33:44 1990 John Gilmore (gnu at cygint)
5718 * infcmd.c -- insert else to avoid 'delete env' coredump when you
5719 delete the whole environment. Karl Berry reported the bug.
5720 * source.c - fix openp to avoid //'s in filenames, which
5721 trigger an Emacs bug causing it to not be able to find files
5722 when running gdb in a window.
5723 * dbxread.c - zap the #if 0 that botches the add-file code.
5724 It seems to work a lot better without all the code commented out.
5726 Fri Jul 20 16:58:46 1990 John Gilmore (gnu at cygnus.com)
5728 * Merge Tiemann's and Ted Goldstein's changes, detailed below,
5731 Tue Jul 17 19:34:33 1990 Ted Goldstein (tedg at golem)
5733 * Makefile - added a ${CFLAGS} to a couple of entries,
5734 added remote-sa.sparc.c
5735 * added remote.sa-sparc.c, a modification of remote.c
5736 which conducts a dialog directly with the SparcStation prom.
5737 * breakpoint.c, infrun.c, sparcdep.c added
5738 remote_insert_breakpoint(), and remote_remove_breakpoint()
5739 to breakpoint.c instead of directly writing breakpoint instructions.
5740 * sparcdep.c on remote_debugging,there is no need
5741 to remove signle step breakpoint instructions.
5742 * main.c added "-epoch" flag and "int epoch_interface" to main.c
5744 * printcmd.c - epoch interface sends lisp expressions to open up
5745 epoch windows on inspection.
5746 * valprint.c - added arrayprint, and addressprint and made adding
5747 format controls easier
5748 * wait.h added a couple of undef's because we were getting
5749 complaints about WSTOPSIG and WTERMSIG begin redefined.
5752 Wed Jul 4 05:27:51 1990 Michael Tiemann (tiemann at masham)
5754 * symtab.c (decode_line_1): Add support for handling method stubs

5759 * values.c (baseclass_addr): Run loop from INDEX+1 to
5760 N_BASECLASSES; otherwise, we can still get into a loop.
5761 @@ This should be restructured to use a cleaner search strategy.
5763 Sun Jul 1 12:28:51 1990 Michael Tiemann (tiemann at masham)
5765 * dbxread.c (define_symbol,read_type): Grok GNU C++'s new

5769 Fri Jun 29 01:03:46 1990 Michael Tiemann (tiemann at masham)
5771 * symtab.c (list_symbols): add ability to set breakpoints on all
5772 the functions which match a particular regular expression.
5774 Tue Jun 26 04:26:29 1990 Michael Tiemann (tiemann at masham)
5776 * cplus-dem.c (cplus_demangle): New parameter ANSI says whether we
5777 should print ANSI qualifiers (such as `const' and `volatile').
5778 All callers changed to call with ANSI == 1, except from
5779 `check_method_stub', which uses old-style syntax.
5781 * symseg.h (struct fn_field): Remove unneccessary `args' field.
5782 * symtab.h (TYPE_FN_FIELD_ARGS): Redefined.
5784 * values.c (check_stub_method): New function.
5786 * cplus-dem.c (do_type): Handle "long long" (encoded as 'x').
5788 * dbxread.c (read_type): Handle new GNU C++ method type stubs.
5789 * valprint (type_print_base): Ditto.
5791 * symtab.c (gdb_mangle_typename): New function.
5793 Tue Jun 5 00:18:43 1990 Michael Tiemann (tiemann at gzilla)
5795 * breakpoint.c (catch_command): New function. Provides a
5796 mechanism to set breakpoints based on catch clauses.
5797 (disable_catch): Similar, but disables breakpoints on catch
5799 (delete_catch): Similar, but deleted breakpoints on catch clauses.
5801 Sun Jun 3 22:54:08 1990 Michael Tiemann (tiemann at gzilla)
5803 * blockframe.c (blockvector_for_pc): New function.
5804 * blockframe.c (block_for_pc): Changed to call
5805 `blockvector_for_pc' and get the block itself.
5807 * stack.c (catch_info): New function. Prints info about
5808 exceptions which can be caught in the current frame.
5809 * stack.c (print_frame_label_vars): New function. Similar to
5810 `print_frame_local_vars'.
5811 * stack.c (print_block_frame_labels): Prints out labels that are
5812 defined in this frame. These labels are exceptions that can be
5815 * dbxread.c: Updated to handle N_CATCH symtab types.
5817 Thu May 3 22:10:00 1990 Michael Tiemann (tiemann at teacake)
5819 * valprint.c (everywhere): TYPE_NAME (TYPE) no longer comes in the
5820 form "struct ..." for GNU C++. Don't flush any part of TYPE_NAME
5821 when printing the type.
5823 Wed May 2 22:43:04 1990 Michael Tiemann (tiemann at teacake)
5825 * valprint.c (val_print): Use `baseclass_addr' to access the
5826 baseclasses pointed to via the derived class object at VALADDR.
5828 * values.c (baseclass_addr): New function. Casts derived pointers
5829 to baseclass pointers taking virtual baseclasses and multiple
5830 inheritance into account.
5832 Sat May 5 12:39:18 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5836 Fri May 4 12:12:55 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5838 * breakpoint.c (watch_command, bpstat_stop_status): Deal with
5839 exp_valid_block field correctly.
5841 * infrun.c (wait_for_inferior): When checking "don't even think
5842 about breakpoints" if stop_signal == SIGTRAP && trap_expected,
5843 also check step_resume_breakpoint.
5844 Insert breakpoints and continue (not step) if
5845 step_resume_break_address != NULL, even if another_trap.
5846 If trap_expected and we enter sigtramp, then set up a
5848 If trap_expected is set when we hit the step_resume_break,
5850 When calling resume and trap_expected says tell resume to step
5851 (2 places), also check step_resume_break_address.
5853 * infrun.c (wait_for_inferior): Don't set
5854 prev_{pc,sp,func_{start,name}} before calling wait ().
5855 Do set them after exiting loop.

5861 * infrun.c (wait_for_inferior, after check for trap_expected > 1):
5862 Restore old code which distinguishes between trap_expected and
5863 running_in_shell, just make the latter take any non-TRAP signal,
5866 * values.c (allocate_value): Zero VALUE_OPTIMIZED_OUT flag.
5868 * Makefile.dist (pinsn.o): Use PINSN_CC to compile.

5925 Mon Apr 23 10:42:21 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5928 findvar.c (get_saved_register): New function.
5929 findvar.c: Rewrite code which called find_saved_register to
5930 call get_saved_register instead.
5932 Sun Apr 22 14:47:51 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5934 * valprint.c (val_print): Change error message printed when

5972 m-m88k.h: Use INIT_{FRAME_PC,EXTRA_FRAME_INFO} to do tdesc stuff.
5973 Use dummy versions of FRAME_CHAIN_*.
