1 Fri Oct 25 16:06:38 1991 Stu Grossman (grossman at cygnus.com)
3 * tm-sparc.h, tm-68k.h (EXTRACT_RETURN_VALUE): fix output of
4 short return values for sparc and 68k. Patch from Paul Eggert.
6 * coffread.c, coredep.c, i386-xdep.c: install patches for
7 SysV/386 3.2 from Mauro DePalma.
9 Fri Oct 25 02:02:13 1991 John Gilmore (gnu at cygnus.com)
11 * core.c (core_file_info), exec.c (exec_file_info): Print file
12 type. Use printf_filtered.
14 * valops.c (value_fetch_lazy): Avoid 0-length fetches.
16 Thu Oct 24 23:06:40 1991 Fred Fish (fnf at cygnus.com)
18 * dwarfread.c: Add casts to remove compiler warnings.
20 * tm-3b1.h, tm-68k.h, tm-altos.h, tm-amix.h, tm-hp300bsd.h,
21 tm-hp300hpux.h, tm-isi.h, tm-news.h, tm-pn.h, tm-sun2.h,
22 tm-sun3.h: Remove locally duplicated code for calling functions
23 in the inferior. The only differences were in the specific trap
24 vectors used and whether or not an fpu was present. These are
25 now handled by appropriate definitions of BPT_VECTOR and
26 HAVE_68881 respectively. Other minor obvious cleanups.
28 * valops.c: Correct a minor misspelling.
30 * utils.c: Remove local BSD/USG hacks that are now in libiberty.
32 * dwarfread.c: Remove prototype for dwarfwarn. Does not work
35 Thu Oct 24 09:33:44 1991 John Gilmore (gnu at cygnus.com)
37 * stack.c (frame_command): Always print. Use new
38 frame_select_command to select a frame without printing.
40 * dwarfread.c: Use <varargs.h>, since <stdarg.h> is not portable.
42 Thu Oct 24 01:32:51 1991 Fred Fish (fnf at cygnus.com)
44 * dwarfread.c: New file for DWARF debugging format support.
46 * elfread.c: New file for ELF object file format support.
48 * procfs.c: New file for SVR4 /proc (process file system) support.
50 * tm-amix.h, xm-amix.h, tconfig/amix, xconfig/amix: New files for
53 * xm-svr4.h, tm-svr4.h: New files for SVR4 support.
55 * xm-m68k.h: New file for host machines with m68k cpu.
57 * Makefile.in: Add elfread.c and dwarfread.c to SFILES_MAINDIR.
58 Add elfread.o and dwarfread.o to OBS.
60 * symfile.h: Add "elf" to list of supported formats in comment.
62 * c-exp.y, defs.h, symtab.h, valprint.c: Add three new builtin
63 types to gdb, builtin_type_long_double, builtin_type_complex, and
64 builtin_type_double_complex. Add and use new TARGET_SHORT_BIT,
65 TARGET_INT_BIT, TARGET_LONG_BIT, TARGET_FLOAT_BIT,
66 TARGET_DOUBLE_BIT, TARGET_LONG_DOUBLE_BIT, TARGET_COMPLEX_BIT, and
67 TARGET_DOUBLE_COMPLEX_BIT, as the sizes in bits of the indicated
68 types on the target machine (ala the existing TARGET_LONG_LONG_BIT).
70 * infrun.c: When using SVR4 /proc interface instead of ptrace(),
71 call proc_set_exec_trap() to setup child to stop at first instruction.
73 * inftarg.c: When using SVR4 /proc interface, call proc_wait()
76 * m68k-tdep.c: Add new routines supply_gregset(), fill_gregset(),
77 supply_fpregset(), and fill_fpregset(), which are machine
78 dependent support routines for SVR4 /proc interface.
80 * utils.c: Add warning_setup() and warning(). Warning() behaves
81 the same as error() except that it returns normally rather than
82 jumping back to command level. Modules that don't want to call
83 warning() for some reason, but want to produce their own warnings,
84 can call warning_setup() to ensure compatibility with the way
85 warning() and error() deal with the terminal.
87 * symtab.c: Make internal errors produce more useful messages.
89 * tm-68k.h: Move code that is duplicated in almost every single
90 m68k based machine's configuration files to this common file.
91 Duplications in the configuration files still need to be removed
94 * infrun.c (child_create_inferior): System V versions must call
95 setpgrp() with no arguments, to comply with prototyping typically
98 * munch: Add support for SVR4 style nm output.
100 * dbxread.c, mipsread.c symmisc.c, symtab.c: Remove the object
101 file specific fields from the partial symbol table structure and
102 replace them with a pointer to private data for each different
103 flavor of object file reader to initialize appropriately.
105 Wed Oct 23 09:38:20 1991 John Gilmore (gnu at cygnus.com)
107 * xconfig/sun[34]os4: Add note about strstr botch on sunos4.0.3c
110 * mipsread.c (fixup_undef_type): New function. If a struct /
111 union / enum is defined in a header file but nowhere else used,
112 (by typedefing, pointer referencing or declaration) the mipsread code
113 builds the complete tree for the structure but leaves its code as
114 TYPE_CODE_UNDEF as it doesn't know what kind of aggregate it is.
115 Guess its type based on the details of the members.
117 Tue Oct 22 18:04:32 1991 Stu Grossman (grossman at cygnus.com)
119 * infrun.c (wait_for_inferior): Check return value from
122 Mon Oct 21 17:47:03 1991 Stu Grossman (grossman at cygnus.com)
124 * infrun.c (wait_for_inferior): fix stepi/nexti that was broken
125 by my last edit to this routine.
127 Mon Oct 21 14:27:43 1991 John Gilmore (gnu at cygnus.com)
129 * tm-sun3.h (FIX_CALL_DUMMY): problem with cross debugging.
130 FIX_CALL_DUMMY does unaligned accesses and/or forgets to byte swap
131 the values before putting them into the dummy code. (From Peter
134 Mon Oct 21 10:04:39 1991 Steve Chamberlain (steve at rtl.cygnus.com)
136 * configure.in: added ebmon target.
138 Wed Oct 16 22:49:58 1991 John Gilmore (gnu at cygnus.com)
142 * Makefile.in: Roll VERSION to 4.2.
143 * README, TODO, WHATS.NEW: Update.
145 * core.c (core_open): Improve error message for bad file.
146 Pass .reg virtual memory address to fetch_core_registers to help
147 it find the registers in the core-file header.
148 * coredep.c (fetch_core_registers): Take new argument, use it,
149 and pass it to register_addr to locate the block of registers.
150 * xm-mips.h: Update KERNEL_U_ADDR for new scheme. Cleanup a bit.
152 * dbxread.c (read_dbx_symtab, process_one_symbol): Handle
153 Sequent N_FN_SEQ like everybody else's N_FN.
155 * main.c: Circumvent SCO cc bug with #if !!defined(USG).
156 * tm-i386v.h: #endif guck.
157 * xconfig/i386*: Remove -Dgetpagesize()=4096 kludge.
158 * xconfig/i386sco: Add HAVE_STRSTR to avoid ANSI bdeath.
159 * xconfig/tahoe: Add REGEX, which seems to be missing.
161 * coredep.c: Add <sys/types.h> for SCOnix.
162 * dbxread.c (read_dbx_symntab): Avoid coredump on malformed file.
163 * printcmd.c (print_formatted): Flush output before disassembly.
165 Tue Oct 15 20:12:32 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
167 * doc/refcard.tex (sec "Working Files"): consistent metavars and
168 other improvements, due to comments by François Pinard
169 (pinard@iro.umontreal.ca)
171 * doc/gdb.texinfo (appendix "Installing GDB"): changes in
172 configure, and improvenets related to Pinard's refcard comments
174 Tue Oct 15 08:45:12 1991 John Gilmore (gnu at cygnus.com)
176 Changes from Fred Fish:
177 * tm-68k.h (FPI_REGNUM): Add.

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

210 generic routines for calling inferior functions.
212 * blockframe.c (inside_main_scope, inside_entry_scope): New.
214 * copying.awk: Filter formfeeds out of copying & warrantee.
215 Make them available as `show copying' and `show warrantee' also.
216 * main.c (print_gnu_advertisement): Advt `show' commands.
218 Thu Oct 10 17:25:47 1991 John Gilmore (gnu at cygnus.com)
220 * mach386-xdep.c: Even when cross-compiling, leave in the
221 core-file reading code.
222 * core.c (get_core_registers): Avoid coredump if no .reg section.
224 Wed Oct 9 17:03:34 1991 John Gilmore (gnu at cygnus.com)
226 * mipsread.c, coffread.c: initialise TYPE_VPTR_FIELDNO to -1.
227 This avoids coredumps under `set print object on' in value_headof
228 (called erroneously by value_from_vtable_info) for `p &struct'
229 or `p *struct'. From Peter Schauer.
231 Mon Oct 7 00:06:52 1991 John Gilmore (gnu at cygnus.com)
233 * Makefile.in: Roll version to 4.1.2.
234 * dbxread.c: Use aout64.h, not a.out.gnu.h. Get external symbol entry
235 size from BFD (but, FIXME, we don't yet read external nlists's and
236 convert them to internal nlists's before handling them -- we still
237 assume they have the same size and alignment.) Use SET_NAMESTRING
239 * exec.c (exec_file_command): Move dead coff-encapsulation code
241 * m88k-tdep.c, m88k-xdep.c: Remove encap test and #inc <a.out.h>.

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

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

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

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

570 Tue Sep 17 08:37:41 1991 John Gilmore (gnu at cygint.cygnus.com)
572 Add Andrew Beers' changes for Modula-2 support. His ChangeLog
573 entries are enclosed herein. Not all of these changes
574 have been merged into the master GDB sources -- check the
575 ChangeLog above here for the merge log.
577 Mon Jun 3 17:05:45 EDT 1991
579 m2-exp.y Created. Tested outside of GDB for a few days. Proper
580 operators were added, C specific operators and tokens
581 removed. yylex() revamped to some extent. Still things
582 missing from the grammar, such as sets.
583 Tested for two weeks in GDB v3.5.
585 Tue Jun 11 17:23:48 EDT 1991
587 m2-exp.y Added boolean constants TRUE and FALSE to the grammar
588 so they are built-in. Sort of a hack.
590 Fri Jun 14 12:53:51 EDT 1991
592 m2-exp.y Added range checking for numeric constants. Any numeric
593 constant is assumed to be of builtin type INTEGER unless:
594 (1) it is octal or hexadecimal, in which case it is a
595 CARDINAL; (2) it is too big to fit into an INTEGER, in
596 which case it is a CARDINAL.
597 eval.c Added simple range checking for +, -, and * on integers.
598 Doesn't work very well for *, since 6 * 1,000,000,000 =
599 1,705,032,704, which fails the simple test of result >=
600 first_operand, no matter in what order the operands are.
602 Tue Jun 18 14:11:30 EDT 1991
604 Broke the parser into parts, one containing the C grammar and the other
605 containing code to be shared by all of the grammars.
607 The following files no longer exist:
612 The following files were added:
614 c-exp.y (The C grammar)
615 m2-exp.y (The Modula-2 grammar)
616 parser-code.c (Code that is shared by the above grammar)
620 Makefile.dist Changed to reflect the above dependencies. NOTE: It is
621 now necessary to use the Bison compiler compiler, since it
622 will generate function/variable prefixes other than yy.
624 Tue Jun 18 16:47:49 EDT 1991
626 symtab.[ch] Added the external variable working_lang, than holds the
627 value of the current working language.
628 Added the ennumerated type language_mode, with the values
629 language_auto and language_manual, the former meaning that
630 GDB sets working_lang as needed, and the latter meaning
631 that the value of working_lang is totally under user
633 symtab.[ch] Added the Modula-2 pervasive types INTEGER, CARDINAL,
634 REAL, BOOLEAN and CHAR. Also added the type codes
635 TYPE_CODE_BOOL and TYPE_CODE_CHAR.
636 utils.c Added set_language_command and show_language_command to
637 implement the GDB support commands "set language" and
639 expression.h A number of identifiers were added to the type exp_opcode
640 to facilitate Modula-2 builtin functions, integer
641 division, and array indexing.
643 Wed Jun 19 13:25:58 EDT 1991
645 language.h Added the macro STRICT_TYPE, which evaluates to non-zero
646 if the language specified by working_lang requires the use
647 of strict typing of expressions. Eventually, even this
648 will be able to be changed by the user.
649 Added the macro RANGE_CHECK, which evaluates to non-zero
650 if the language specified by working_lang requires the
651 checking of a value against the domain of its type.
652 Eventually, even this will be able to be changed by the
654 language.[ch] Predicates involving types (simple_type, ordered_type,
655 same_type, integral_type, numeric_type, character_type,
656 boolean_type, float_type) are added. These predicates are
657 based on the current value of working_lang, and are handy
660 Wed Jun 19 15:39:34 EDT 1991
662 eval.c Added the function type_array_rank which computes the rank
664 valarith.c Added the funtion value_bool, which when given a integer
665 value.h value (ie. struct value *) as an argument, it returns a
666 boolean value (ie. struct value *) true if that integer
667 is non-zero, and a boolean value false otherwise.
668 valprint.c Added cases for TYPE_CODE_BOOL, so Modula-2 BOOLEAN values
669 will print out properly.
671 Wed Jun 19 16:36:34 EDT 1991
673 valops.c Added the function value_capitalize, which returns it
674 value.h argument capitalized if its argument is a lowercase
675 letter, or the argument unchanged if its argument is not a
677 valarith.c Added the function range_check_p, which returns non-zero
678 value.h if its value argument is between the integral bounds upper
680 Added the function range_check_enum_p, which makes sure
681 that its value argument is a valid member of the domain of
683 Added the function range_check_range_p, which makes sure
684 its value argument lies between the upper and lower bounds
685 of its type argument, which must be a ranged type.
686 Added the function check_array_index, which range and type
687 checks an index of an array.
688 Added the function value_multi_subscript, which computes
689 array[idx1,idx2...idxN], given a value array and an array
690 of values representing indicies.
691 values.c Changed value_from_long to work with TYPE_CODE_CHAR and
692 unpack_long to work with TYPE_CODE_BOOL and
695 Wed Jun 19 18:04:08 EDT 1991
697 symtab.c Stored pervasive types in a structure and make
698 lookup_pervasive_type() a lookup function that was based
699 on working_lang. If lookup_pervasive_type() returned
700 non-zero, then that value was returned (a fix, since
701 before it simply wouldn't return the pervasive type.)
702 language.h Added the macro CAST_IS_CONVERSION, which evaluates to
703 non-zero if the language specified by working_lang means
704 "conversion" when it says "cast".
705 valops.c Added the function value_real_cast(), which performs a
706 value.h *cast*, not a *conversion*, which is what value_cast()
707 does when it can. In particular,
708 value_cast(<float_type>,4) = 4.0, while
709 value_real_cast(<float_type>,4) = some mess.
710 eval.c Modula-2 builtin functions implemented: ABS, CAP, CHR,
711 parser-code.c FLOAT, HIGH, MAX, MIN, ODD, ORD, TRUNC, and VAL.
712 expression.h Added macros MAX_OF_TYPE and MIN_OF_TYPE to work with MAX
713 and MIN on integral types. *NOTE*: These are currently
714 hardcoded to work only if there are 8 bits per storage
716 eval.c Made logical functions call value_bool to return a
717 properly typed boolean value, based on working_lang.
719 Thu Jun 20 11:55:27 EDT 1991
721 valprint.c Types now print out in a Modula-2 fashion. This works for
722 the cases when the type is printed out step-by-step, that
723 is, it doesn't work when the name of a structured type
724 (which includes the keyword "struct", etc.) is simply
726 FIXME: Perhaps this is bad. Parts of it seem to kludgey,
727 since type specifications in C and Modula-2 are very
728 different. The C printing of a type is very recursive,
729 whereas in Modula-2 it is generally very simple. C has
730 type prefixes and suffixes, which have no real analogue in
731 Modula-2. Maybe type_print() should call a language
732 specific type printer. This is also advantageous if we
733 compile GDB to exclude some of the languages. We'll just
734 leave those functions out.
736 Thu Jun 20 16:57:10 EDT 1991
738 dbxread.c When reading the complete symbol table in (via
739 psymtab_to_symtab()), the number and types of function
740 arguments are added to a function type. define_symbol()
741 calls add_param_to_type() to accomplish this.
742 Assumption: when we come across a function definition
743 (N_FUN symbol with an 'f' or 'F' in the name), its
744 arguments will appear before another function definition.
745 When a function is found, a pointer to its type is placed
746 in the global in_function_type. Changes that
747 add_param_to_type() makes are to this global.
748 valprint.c The type of a function now includes (for Modula-2) the
749 types of its parameters.
750 eval.c Type checking and a check for the proper number of
751 arguments is now done for function calls. Not sure of the
752 impact this has on C++ member function yet.
754 Thu Jun 20 19:58:48 EDT 1991
756 valprint.c Rewrote the type printer. Broke it into two language
757 specific parts, adding the functions type_print_m2() and
759 An unfortunate consequence is this: if you debugging a C
760 program in Modula-2 mode (why?), info types does not work
761 well with regular expressions, since the types are printed
762 out in Modula-2 terminology, but stored in C terminology.
763 language.[ch] Added the functions new_type_last(), type_keyword(), and
764 type_sep() to aid in the printing of typedefs.
765 symtab.c Made the printing of typedefs as language independent as
766 possible through calls to new_type_last(), type_keyword(),
769 Fri Jun 21 11:50:26 EDT 1991
771 dbxread.c Check all incoming ennumerated types. If it looks like
772 Modula-2's BOOLEAN type, then change the type_code of the
773 type to TYPE_CODE_BOOL so we can process it as a boolean
775 valprint.c Replaced some of the 0x%x with calls to sprintf and
776 hexformat() in val_print().
777 language.[ch] Added the function hex_to_string(), which converts its
778 integral argument to a hexadecimal number (format is
779 language based) and returns the result as a string.
781 Mon Jun 24 12:25:07 EDT 1991
783 valprint.c Some functions call type_print_1() directly, instead of
784 value.h using type_print(), so they can specify where (column) to
785 print things. Since type_print() takes care of language
786 dependence, that needs to be called first. Added a
787 parameter depth to type_print() (so it is now like
788 type_print_1). Changed type_print to type_print_at, and
789 made type_print a macro that passes a depth argument of
791 symmisc.c Changed all calls to type_print_1 to calls to
793 Makefile.dist Made it possible to build GDB for a specific set of
794 depend languages. Do this by passing a definition for the macro
795 LANGS to make. LANGS should be a string containing a
796 space-separated list of language names (ie. LANGS="c m2").
797 The default is to build all languages. Note that grammar
798 files must follow the naming convention of <lang>-exp.y.
799 gdb.lang This holds the current value of the LANGS macro. It is
800 examined every time make is called, and is updated if
802 eval.c Added #ifdef _LANG_<lang> to these files.
803 expread.c Still need to add them to dbxread.c and coffread.c.
811 Mon Jun 24 16:33:11 EDT 1991
813 language.[ch] Added the functions hexformat_pre() and
814 hex_to_string_pre(), which take a prefix argument to
815 include in the format string. Thus, hexformat_pre("08") will
816 return "0x08x" (if the working language is language_c).
817 Made hexformat() and hex_to_string() calls to the above
818 with "" as the prefix argument.
820 am29k-pinsn.c, arm-pinsn.c, breakpoint.c, convex-tdep.c, exec.c, core.c,
821 dbxread.c, i386-pinsn.c, i386-stub.c, i386-xdep.c, i960-pinsn.c,
822 infcmd.c, inflow.c, m68k-pinsn.c, m68k-stub.c, m88k-pinsn.c,
823 mips-pinsn.c, mips-tdep.c, ns32k-pinsn.c, printcmd.c, pyr-pinsn.c,
824 pyr-tdep.c, pyr-xdep.c, remote-vx.c, remote.c, solib.c, source.c,
825 stack.c, sun386-xdep.c, symfile.c, symm-xdep.c, symmisc.c, tahoe-pinsn.c,
826 valprint.c, vax-pinsn.c
828 Changed all occurences of 0x%[0-9]*l*x in printf format strings to
829 calls to hexformat() and hex_to_string(). Format strings without
830 the leading "0x" were ignored.
832 depend Updated to take the above into account.
835 Tue Jun 25 15:27:18 EDT 1991
837 symtab.h Added the types range_mode_t, range_check_t, type_mode_t,
838 and type_check_t to keep track of the current state of
839 range and type checking.
840 main.c Added the variables range_mode, range_check, type_mode,
841 and type_check to record the current state of range and
842 type checking. Added initialization code to main().
843 language.h Changed the macros STRICT_TYPE and RANGE_CHECK to examine
847 Tue Jun 25 17:57:08 EDT 1991
849 dbxread.c process_one_symbol() updates the variable (enum language)
850 source_lang based on the extension of the filename
851 contained in the N_SO sybmol that started this symtab.
852 When end_symtab() is called, the value of source_lang is
853 put into the language field.
854 stack.c select_frame() sets working_lang (and possibly type_check
855 and range_check) to the language field of the symtab
856 associated with the frame that is selected if working_mode
857 is language_auto. If working_mode is language_manual, a
858 warning is printed and working_lang is not set.
859 language.c Added the function set_type_range(), which sets the value of
860 type_check and range_check (if their modes call for
861 automatic setting) based on the current value of
862 working_lang. A non-zero argument will cause the current
863 settings to be output.
866 Wed Jun 26 14:51:40 EDT 1991
868 eval.c Added range checks on assignment.
869 m2-exp.y Added the grammar for sets to the language. Currently,
870 these do not do anything except print an error message.
872 Wed Jun 26 17:01:04 EDT 1991
874 m2-exp.y Added the ability for parse_number() to parse negative
875 numbers. A global flag is set upon encountering a unary
876 minus. This was done to make, for example, 1 parse as a
877 CARDINAL, and not as an integer, per Wirth's examples in
878 Programming in Modula-2 ed.4.
879 valprint.c Added support for "set radix 2" by then setting
880 output_format to 't'.
881 eval.c Implemented range checking on subrange types. Added calls
882 to range_check_range_p for BINOP_ASSIGN and BINOP_VAL.
883 Implemented MIN and MAX for ennumerated types. The
884 minimum value of an ennumerated type is defined by Wirth
885 as the first identifier, and the maximum as the last.
886 m2-exp.y Made octal numbers ending with "B" be characters and those
887 ending with "C" be numbers, per Wirth's book. (p. 34)
889 Thu Jun 27 14:11:52 EDT 1991
891 stack.c select_frame() now only sets working_lang, it does not
892 notify the user. If working_mode is language_manual, then
893 a warning is issued once.
894 main.c At the end of each call to execute_command(), working_lang
895 is checked against the local static (enum language)
896 current. If they differ and working_mode is
897 language_auto, the new settings of language, type and
898 range checking are printed out.
899 stack.c Modified frame_info() to include the language of the
900 current frame in the output of "info frame".
901 language.[ch] Added the function language_str() which returns the name
902 of the current language.
904 Fri Jun 28 15:33:14 EDT 1991
906 m2-exp.y Added the built-in procedures INC, INCL, DEC, and DECL to
907 the language. INCL and DECL currently cause an error,
908 since sets are not implemented yet. INC and DEC are
909 implemented as PREINCREMENT/PREDECREMENT with one
910 argument, and as ASSIGN_MODIFY with two arguments.
911 eval.c Added type checking to the above cases.
912 value.h Added not_lval_constant to the lval_type ennumerated type.
913 not_lval_constant means that the value is a constant
914 value; that is 3 or 'a' or TRUE, not as in a constant
915 identifier. This is used to help coerce numbers such as 3
916 to either signed or unsigned numbers.
917 valops.c Added the function value_coerce_constants() which coerces
918 constant integers as following: if one is a constant and
919 the other is not, the constant's type is set to the type
920 of the other argument. If both are constants and one is
921 signed, the other is converted to a signed constant.
923 Sat Jun 29 17:26:29 EDT 1991
925 valarith.c Added a better range checker. It now checks range
926 (successfully) on integral operations [+-] (signed and
927 unsigned) for any C sized type. Still does not work well
929 int_in_size() returns an integer that is coerced to fit into
930 specified number of bytes.
932 Mon Jul 1 13:04:14 EDT 1991
934 language.[ch] Added the function binop_result_type(), which returns the
935 builtin (struct type *) type that would be the result of a
936 binop on the two values V1 and V2.
938 Wed Jul 3 19:22:53 EDT 1991
940 source.c Extended source_info() to include the source language in
941 the output from "info source".
943 Fri Jul 5 13:48:52 EDT 1991
945 utils.c Moved the support functions for the GDB set/show commands
946 dealing with language into language.c.
947 language.c Added the function language_info(), which displays info
948 about the current working language, type and range check
949 settings. Called via the GDB command "info language".
950 Added an initialization routine _initialize_language(),
951 that sets defaults for the language, type and range
952 variables and sets up the new GDB commands.
953 main.c Language setup moved to language.c.
956 Mon Jul 8 10:10:22 EDT 1991
958 valarith.c Debugged the range checker for arithmetic. Still does not
959 work for multiplication very well.
961 Mon Jul 8 12:40:37 EDT 1991
963 language.[ch] Added the function value_true() which returns non-zero if
964 its argument represents a boolean true value.
965 breakpoint.c Changed breakpoint_cond_eval() to call value_true() to
966 check the truth of an expression.
968 Thu Jul 11 12:51:34 EDT 1991
970 language.[ch] Added the predicate structured_type(), which returns
971 non-zero if the argument is a structured type.
972 Added the predicate pointer_type(), which returns non-zero
973 if the argument is a pointer type.
974 eval.c Added the ability to do addition and substraction on
975 pointers and integers. This case simply bypasses the
978 Thu Jul 11 14:41:42 EDT 1991
981 Added the symbol N_DEFD (0x4a) which is a definition
982 module dependency that is used by the GNU Modula-2
983 compiler and the linker. It is not important to GDB,
984 except that [dbx|coff|mips]read.c should ignore these
987 Fri Jul 12 16:07:00 EDT 1991
989 valprint.c Changed the TYPE_LENGTH(type) >= 0 to TYPE_LENGTH(type) >
990 0 in val_print(). Also added statements to the else part
991 to coerce type (argument to val_print) to a pointer type
992 if it is an "array of unspecified length".
993 valops.c Added the function value_m2_string(), which returns a
994 (value) value which is a constant string, whose type is
995 (ARRAY [0..n] OF CHAR). The length field of the type
996 structure is set to zero, so it will be interpreted as an
997 "array of unspecified length".
998 stack.c Moved the language/frame mismatch check to
999 main.c:execute_command().
1000 main.c The working language is recorded each time
1001 execute_command() is executed. If working lang has
1002 changed during its execution, then the new
1003 language/type/range info is printed out for the user. If
1004 the working language does not match the language of the
1005 frame, a warning is issued.
1007 Sat Jul 13 16:16:39 EDT 1991
1009 eval.c Moved all the type-checking stuff for operators to
1010 language.[ch] language.c. This is so we can keep language-specific
1011 stuff (like for what type operators are defined) in
1013 language.[ch] Added the function binop_type_check(), which checks to see
1014 if its two (value) arguments are type-compatible with its
1015 opcode argument. The opcode should represent an operation
1016 involving an operator. Also added the macro function
1017 unop_type_check, which calls binop_type_check with a
1018 NULL second argument.
1019 expprint.c Added Modula-2 operators to the op_print_tab, so info
1020 expression.h break works correctly. Also added "op_string", which
1021 returns the string corresponding to the (enum exp_opcode)
1022 opcode that is its argument.
1025 Sat Jul 13 18:26:18 EDT 1991
1027 coffread.c Added code to record the type of function arguments with
1028 each paricular function. Code is very similar to that
1030 dbxread.c Moved add_param_to_type() to symtab.c
1031 symtab.[ch] Added function add_param_to_type() from dbxread.c
1033 *** NOTE: The above additions have not been tested.
1035 Mon Jul 15 12:50:47 EDT 1991
1037 langauge.[ch] Added the functions type_error and range_error, which work
1038 like error() except if the type/range mode is set to
1039 *_mode_warn, then they do not do a return_to_top_level(),
1040 but merely print a warning.
1041 Also changed [set|show]_[type|range]_command() to support
1042 the new "warn" feature.
1044 Thu Jul 18 17:50:54 EDT 1991
1046 mipsread.c Added code to record the type of function arguments with
1047 each particular function. Code is very similar to that
1050 *** NOTE: The above additions have not been tested.
1052 Fri Jul 19 11:19:10 EDT 1991
1054 defs.h Added macros MAX_OF_SIZE, MIN_OF_SIZE, UMAX_OF_SIZE, and
1055 UMIN_OF_SIZE, which when given a size of a numeric type,
1056 return the maximum and minimum value it can hold. UMAX...
1057 and UMIN... return the result for unsigned types.
1058 symtab.h Added the macros MAX_OF_TYPE and MIN_OF_TYPE to operate on
1059 struct types. They call above macros.
1060 dbxread.c Renamed the MAX and MIN_OF_TYPE macros to ..._OF_CTYPE to
1061 avoid a name conlict with the above.
1062 c-exp.y Added range checking on numeric constants in
1063 parse_number() for completeness.
1064 valarith.c Made binop_user_defined_p() and unop_user_defined_p()
1065 return 0 if working_lang is not language_c.
1067 Thu Aug 8 14:17:22 EDT 1991
1071 breakpoint.c Documentation strings of some commands changed to
1072 eliminate the references to the C language where
1075 Tue Aug 13 15:48:03 EDT 1991
1077 m2-exp.y Added qualified identifiers to the grammar. The semantics
1078 are slightly different from those of the GDB operator ::
1080 m2-exp.y Added a rule to each grammar of the form: start ::= exp |
1081 type_exp, where type_exp is any valid type expression.
1083 eval.c Added the opcode OP_TYPE, and an error case in eval.c.
1084 printcmd.c Modified ptype_command() so it actually parses the input
1085 (necessary for type expressions with scope qualifiers).
1086 Added the function ptype_eval() which expects an
1087 expression composed of one OP_TYPE element.
1088 *.[ch] Replaced all occurences of parse_c_expression with
1090 *.[ch] Replaced all occurences of parse_c_1 with parse_exp_1
1092 [End of ChangeLog entries from Andrew Beers for Modula-2 support.]
1094 Mon Sep 16 17:19:46 1991 John Gilmore (gnu at cygnus.com)
1096 Small fixes from Peter Schauer:
1098 * infrun.c (child_attach): Lint.
1099 * solib.c (find_solib): Handle shared libs version 2.
1101 Small fixes from David Wood:
1103 * xm-ultra3.h (SYS_SIGLIST_MISSING): Typo.
1107 * remote-vx.c: Move <stdio.h> to top, for FILE. Fix from
1108 John S <basrai%kanga.dnet@c3po.sm-alc.af.mil>.
1110 * utils.c (wrap_here): Avoid wrap action of fputs_filtered if
1111 chars_per_line is at maximum (user typed `set width 0'). Fix
1112 from Andreas Schwab <schwab@ls5.informatik.uni-dortmund.de>.
1114 Tue Sep 17 17:31:04 1991 Stu Grossman (grossman at cygnus.com)
1116 * coredep.c: include ptrace.h where necessary.
1117 * mipsread.c(parse_lines): fix unsigned char problem that was
1118 messing up line numbers on SGI's and possibly other MIPS based
1120 * infrun.c (child_create_inferior): use better test to check
1121 return val from setpgrp().
1122 * tm-irix3.h, xm-irix3.h, tconfig/irix3, xconfig/irix3: add these
1123 for sgi/irix support.
1125 Wed Sep 18 04:33:31 1991 Per Bothner (bothner at cygnus.com)
1127 * mipsread.c (parse_symbol): Put non-static procedures
1128 in the global block.
1130 Fri Sep 13 00:14:52 1991 John Gilmore (gnu at cygnus.com)
1132 Patch together `text_start' and `text_end' for 29K port.
1134 * exec.c (exec_command): If NEED_TEXT_START_END, define the
1135 variables and set them based on the exec file.
1136 * am29k-tdep.c: declare text_start.
1137 * valops.c (call_function_by_hand): declare text_end.
1139 * inferior.h: Eliminate CANNOT_EXECUTE_STACK in favor of
1140 defining CALL_DUMMY_LOCATION as BEFORE_TEXT_END. This is
1141 because machines that do this will also have to know to
1142 set NEED_TEXT_START_END. Besides, it was a redundant way to
1144 * tm-29k.h, tm-convex.h, tm-np1.h: Eliminate
1145 CANNOT_EXECUTE_STACK, define CALL_DUMMY_LOCATION and
1146 NEED_TEXT_START_END.
1148 Thu Sep 12 00:22:24 1991 John Gilmore (gnu at cygint.cygnus.com)
1150 AMD 29000 changes from David Wood <wood@david.ultra.nyu.edu>:
1152 * Makefile.in (CLIBS): Put XM_CLIBS and TM_CLIBS at end.
1153 Pass MUNCH_DEFINE to munch whenever we run it.
1154 * am29k-pinsn.c (print_insn): Handle NOP specially. Avoid %#x
1155 format string; use 0x%x instead.
1156 * am29k-tdep.c: Use DUMMY_SAVE_GREGS and RETURN_REGNUM.
1157 * ultra-xdep.c, xm-ultra.h: New files for Ultracomputer host system.
1158 * xm-rtbsd.h: New host support for RT/PC running BSD Unix.
1159 * inflow.c: Handle `short' process group IDs.
1160 * infptrace.c (fetch_register): Support CANNOT_FETCH_REGISTER,
1161 and check for ptrace errors.
1162 * coffread.c (SDB_REG_TO_REGNUM): Define if not already.
1163 (coff_symfile_init): Initialize text_bfd_scnum.
1164 (read_coff_symtab): Use it to find the text [and absolute?] sections.
1165 * ../config.sub: Add vendor nyu and os "sym[1-9]*".
1166 * configure.in: Add hosts rtpc-*-* and a29k-*-*.
1167 Merge target arm case with other "easy" cases. Add target
1168 cases a29k-*-none (rehack of am29k), a29k-*-kern (remote to
1169 Ultracomputer kernel), and a29k-*-sym1 (ultracomputer OS's user
1171 * minimon.h, remote-adapt.c, remote-mm.c: Add.
1172 * munch: Cope with RT/PC putting fns in data segment.
1173 Restore ability to override `nm' by specifying MUNCH_NM.
1174 * xconfig/rtbsd, xconfig/ultra3: New host systems.
1175 * tconfig/a29k: Rename from tconfig/am29k. Add remote-mm
1176 and remote-adapt. Remove encapsulated coff #define's (the
1177 support should go in BFD, and gdb shouldn't know or care).
1178 * tconfig/a29k-kern: Same, but for remote kernel debugging.
1179 * tconfig/ultra3: For debugging user processes on Ultra3/Sym1.
1180 * tm-29k.h: Update BADMAG (though it should go away).
1181 Allow the register definitions to be overridden in another
1182 tm-file. Fix SR_REGNUM. Add a mess of _REGNUM's. Separate
1183 RETURN_REGNUM from GR96_REGNUM and DUMMY_SAVE_GREGS from
1184 DUMMY_SAVE_GR96, for handling kernel calling conventions
1185 that use GR64+ rather than GR96+.
1186 * tm-ultra3.h: New file, for use on Ultra3 Unix as well as for
1187 remote debugging of Ultra3 kernel. Includes tm-29k.h and
1188 overrides various things.
1190 * remote-mm.c (mm_attach, mm_wait): Handle attach like
1191 child_attach does, making a clean stop in the newly attached
1193 * remote-eb.c: Lint.
1195 * coffread.c: Make coffread independent of any particular
1196 variant of COFF. Avoid #include-ing any particular one except
1197 internalcoff.h. BFD now passes key values for symbol reading
1198 as part of its coff_data structure (LINESZ, SYMESZ, AUXESZ,
1199 and the symbol masks and shifts); use them.
1200 Remove obsolete end_of_text_addr.
1202 * exec.c: Remove unused include files.
1204 Wed Sep 11 19:38:44 1991 John Gilmore (gnu at cygint.cygnus.com)
1206 * Makefile.in (documentation targets): Pass $(M4).
1207 Bugfix from eggert@twinsun.com (Paul Eggert).
1209 * stack.c (down_silently_command): Check for stack existence.
1211 Tue Sep 10 23:08:29 1991 John Gilmore (gnu at cygint.cygnus.com)
1213 * Makefile.in (VERSION): Update to 4.0.3.
1215 Tue Sep 10 09:19:29 1991 John Gilmore (gnu at cygint.cygnus.com)
1217 * core.c (core_file_command): Print frame at coredump with
1218 its level number, by calling print_stack_frame.
1219 * frame.h: Add selected_frame_level, print_stack_frame.
1220 * frame.h, stack.c: Remove print_sel_frame, print_selected_frame.
1221 * convex-tdep.c, convex-xdep.c, infcmd.c, inflow.c, infrun.c:
1222 Change print_sel_frame and print_selected_frame callers to
1225 * dbxread.c (read_ofile_symtab): Avoid empty else clause.
1226 * symfile.c (free_named_symtabs): Ditto.
1227 * main.c (main): wrap_here needs an arg.
1228 * solib.c (find_solib): Avoid memory access if _DYNAMIC is zero.
1229 (solib_add): Avoid noise.
1230 (solib_create_inferior_hook): Lint.
1231 (sharedlibrary_command): Move dont_repeat to here.
1232 * utils.c (error): Call wrap_here to force buffered output.
1234 Small patches from Peter Schauer:
1236 * coffread.c (start_symtab): Free any existing line_vector before
1238 (read_coff_symtab): Ditto for type_vector.
1240 * source.c (lines_to_list): New variable, replacing function.
1241 (all uses): Use as variable.
1242 (_initialize_source): Add 'set listsize' and 'show listsize'.
1243 * utils.c (lines_to_list): Remove function.
1244 * stack.c (print_frame_info): Use as variable.
1245 * defs.h (lines_to_list): Remove declaration.
1247 Mon Sep 9 13:45:57 1991 John Gilmore (gnu at cygint.cygnus.com)
1249 * breakpoint.c (insert_breakpoints): Restore warning about
1250 the program might be running in another process, but only for
1251 systems with this brain death (#ifdef ONE_PROCESS_WRITETEXT).
1252 * xm-hp300bsd.h, xm-mips.h, xm-vax.h: Define it.
1254 * utils.c (error): if error_pre_print is set, print the string
1256 * main.c (main, print_gnu_advertisement, print_gdb_version):
1257 Reformat legalese so it always prints, but acts as an "I'm here"
1258 message while symbols are being read. If any errors occur,
1259 print a few newlines to set off the message and start it at the
1260 left margin. Remove mention of "help" command, and don't yak
1261 about symbol reading.
1262 (catch_errors): Error string is now printed first in case of
1264 * command.c (undef_cmd_error, lookup_cmd): On undefined command,
1265 suggest the "help" command.
1267 * Makefile.in (VERSION): Set to 4.0.2.
1269 Thu Sep 5 23:49:48 1991 John Gilmore (gnu at cygint.cygnus.com)
1271 * .gdbinit: Remove useless "rr" command. Set complaints
1272 to 1 for people debugging gdb.
1274 * breakpoint.c, remote-vx.c: Reword strings printed by
1275 catch_errors callers.
1277 Wed Sep 4 11:07:50 1991 John Gilmore (gnu at cygint.cygnus.com)
1279 * WHATS.NEW: "history write -> history save". Doc "write on/off".
1280 (Fix from kenc@viewlogic.com.)
1282 Fix some infrastructure to be able to cope with host and target
1283 machines with different sized basic types (ints, ptrs, etc).
1284 (Idea from pierre@la.tce.com (Pierre Willard).)
1286 * values.c (value_from_longest): Rename from value_from_long.
1287 Handle pointer types as well as integers, so that targets with
1288 different pointer sizes from the host can be accomodated.
1289 * breakpoint.c, convex-tdep.c, eval.c, expprint.c, printcmd.c,
1290 valarith.c, valops.c, valprint.c, value.h, values.c: Rename
1291 uses of value_from_long to value_from_longest.
1292 * eval.c, findvar.c, printcmd.c, valarith.c, valops.c: Pass
1293 the correct pointer type to value_from_long{est}.
1295 * doc/gdb.texinfo ($_, $__): Describe types of these variables.
1297 * remote-vx.c: Remove obsolete code for calling functions via
1298 vxworks kludge interface (it referenced value_from_long).
1300 * valops.c (value_string): Find malloc with lookup_misc_func, not
1303 Tue Sep 3 18:37:46 1991 John Gilmore (gnu at cygint.cygnus.com)
1305 Make writing to files work properly. (Fixes to BFD are also needed.)
1307 * core.c (core_open): Open file ourselves, read or r/w, depending on
1308 write_files. Use bfd_fdopenr.
1309 * gdbcore.h (write_files): New variable.
1310 * exec.c (write_files): Define variable, add set&show for it.
1311 (exec_file_command): Use write_files to open for read or r/write.
1313 Make shared library reading happen automatically. These changes
1314 are mostly from Peter Schauer <pes@regent.e-technik.tu-muenchen.de>.
1316 * inferior.h (stop_soon_quietly): Add to exported variables.
1317 * infrun.c (child_create_inferior): call solib hook, if defined.
1318 (child_attach): call solib hook, if defined.
1319 * solib.c: Include inferior.h. Add from_tty to so_list as kludge.
1320 (find_solib): Use lookup_misc_func rather than hand-rolled.
1321 (symbol_add_stub): New stub for catch_errors.
1322 (solib_add): Avoid output if !from_tty. Catch errors rather
1323 than just calling symbol_file_add and bombing.
1324 (solib_create_inferior_hook): Interface with the target process
1325 to let it read and alloc shared libs, then figure out what it did.
1327 * core.c (validate_files): Fix typo, soften warning.
1328 (Fix from Hiroto Kagotani <kagotani@cs.titech.ac.jp>.)
1330 * utils.c (fputs_demangled): Avoid duplicate printing if
1331 demangling is off. (Fix from J.T. Conklin <jtc@cayenne.com>.)
1333 * infrun.c (proceed): Cast -1 to (CORE_ADDR) before comparing.
1334 (Fix from pierre@la.tce.com (Pierre Willard).)
1336 * main.c (catch_errors): Change argument to a char * from an int,
1337 since a char * can point to a struct full of glop, but an int
1338 is not guaranteed to be able to hold a pointer.
1339 * breakpoint.c (breakpoint_cond_eval, bpstat_stop_status,
1340 breakpoint_re_set_one, breakpoint_re_set): Adapt.
1341 * core.c (core_open, solib_add_stub): Adapt.
1342 * remote-vx.c (symbol_stub, add_symbol_stub, callers): Adapt.
1344 Wed Aug 28 18:18:05 1991 John Gilmore (gnu at cygint.cygnus.com)
1346 * Makefile.in: Update VERSION to 4.0.1. Evade GNU Make bug
1347 by adding .NOEXPORT target.
1349 Fri Aug 23 17:14:25 1991 John Gilmore (gnu at cygint.cygnus.com)
1353 * Makefile.in (VERSION): Roll to 4.0.
1354 (gdb.tar.Z): Make refcard.ps as well, for shipment.
1356 Fri Aug 23 14:07:09 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1358 * doc/gdb.texinfo: minor rewordings, crossref to ptype from print,
1361 * doc/Makefile, Makefile.in: generate "gdb-all.texi" rather than
1364 * doc/rdl-apps.texi: renamed from rdl-apps.texinfo
1366 * Makefile.in, doc/Makefile, doc/.Sanitize, doc/gdb.texinfo:
1367 reflect above name change
1369 * WHATS.NEW: correct pointer to refcard.
1371 * doc/gdb.texinfo: update New Features, Installing
1373 * doc/gdbint.texinfo: add short description of configure +template
1375 Fri Aug 23 11:46:08 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1377 * doc/gdb.texinfo: update, fix bugs in "Installing" appendix
1379 Fri Aug 23 01:02:00 1991 John Gilmore (gnu at cygint.cygnus.com)
1381 * Makefile.in: Add config.sub, make doc/rdl-apps.texinfo for
1382 tar file, add dependencies for referenced doc files.
1384 Thu Aug 22 22:17:06 1991 Stu Grossman (grossman at cygint.cygnus.com)
1386 * coffread.c, symfile.c, stack.c: saberized.
1388 Thu Aug 22 16:20:27 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1390 * doc/refcard.tex: permuted Essential Commands sec
1392 * doc/gdb.texinfo: new C++ chapter; revised installation appendix;
1394 set/show symbol-reloading
1395 default set complaints 0
1397 RET-repeat disabled after prompted long displays
1398 processID (attach) interpretation of 2nd GDB cmdline arg
1400 Thu Aug 22 14:05:47 1991 Stu Grossman (grossman at cygint.cygnus.com)
1402 * expread.y, coffread.c, dbxread.c, target.c, mem-break.c,
1403 cplus-dem.c, values.c, valprint.c, symfile.c, remote.c,
1404 breakpoint.c, main.c: lint.
1406 Thu Aug 22 02:02:26 1991 John Gilmore (gnu at cygint.cygnus.com)
1408 Install new configuration scheme for GDB and friends.
1410 * config.sub: Translate ordinary names to three-part names.
1411 * configure: Use three-part names internally.
1412 * configure.in: Translate three-part names to filenames.
1414 * README, WHATS.NEW: Update for gdb-4.0.
1415 * Makefile.in: Roll VERSION to 3.99.
1417 Wed Aug 21 18:21:09 1991 John Gilmore (gnu at cygint.cygnus.com)
1419 * infptrace.c (KERNEL_U_ADDR_BSD): Include a.out.gnu.h.
1420 * i960-tdep.c, m68k-tdep.c, sparc-tdep.c, tm-i960.h,
1421 tm-m68k.h, remote-nindy.c: Change ext_format_XXX structs
1422 to single structures rather than arrays; when passing
1423 their address, use &. This avoids trouble with bdead compilers.
1424 * mcheck.c: Don't include <stdlib.h>; just declare "void abort();"
1425 instead. This avoids portability headaches.
1426 * mips-tdep.c (mips_do_registers_info): Only print FP regs if
1428 * source.c (open_source_file): Avoid ANSI const bdeath by
1429 skipping declaration and then casting result value.
1430 * tm-hp300bsd.h: Clarify comment.
1431 * utils.c (strstr): Result is const char *; ANSI bdeath.
1432 * xm-hp300bsd.h: Define HOST_BYTE_ORDER. Redefine INT_MIN,
1433 since system include file defines it differently from "defs.h",
1434 though the two are equivalent for our purposes.
1435 * tconfig/hp300bsd: Add m68k-tdep.o.
1437 Tue Aug 20 16:01:11 1991 John Gilmore (gnu at cygint.cygnus.com)
1439 * tconfig/sun*4: Remove warnings about system assembler.
1441 Mon Aug 19 13:44:46 1991 John Gilmore (gnu at cygint.cygnus.com)
1443 * mcheck.c: Avoid warning about undeclared abort fn.
1444 * tm-sparc.h (PC_ADJUST): Avoid calling error() from this;
1445 it causes recursive calls to error() when used in cleanups.
1446 To do so requires that we make it a function, so we do.
1447 * sparc-tdep.c (sparc_pc_adjust): New implem of PC_ADJUST.
1448 * utils.c (do_cleanups): Remove the current cleanup from the
1449 chain *before* calling it, in case error() is called from it.
1450 The result won't be pretty, but won't be an infinite loop either.
1452 Mon Aug 19 00:41:04 1991 Michael Tiemann (tiemann at cygint.cygnus.com)
1454 * dbxread.c (read_struct_type): Grok anon structs for C++.
1455 (vb_name, vptr_name): Null terminate these strings.
1457 Fri Aug 16 08:31:03 1991 John Gilmore (gnu at cygint.cygnus.com)
1459 Minor bug fixes from BSD Net2 gdb:
1461 * blockframe.c (get_prev_frame_info): If FRAME_CHAIN_COMBINE
1462 returns 0, there is no previous frame.
1463 * breakpoint.c (commands_command): If !from_tty, don't call
1464 input_from_terminal_p().
1465 * dbxread.c (record_misc_function): Speed up slightly.
1466 (compare_psymbols): Ditto.
1467 * infcmd.c (do_registers_info): Take a second argument to
1468 determine whether to print float registers. "info registers"
1469 does not do so anymore. "info all-registers" does, now.
1470 * mips-tdep.c, pyr-tdep.c (xxx_do_registers_info): Take second
1472 * tm-mips.h, tm-pyr.h (DO_REGISTERS_INFO): Pass second arg.
1473 * inflow.c (initialize_inflow): Set tflags_ours correctly.
1477 * breakpoint.c (bpstat_do_actions): Use a cleanup to restore
1478 executing_breakpoint_commands if we are interrupted by error.
1479 * coffread.c (init_lineno): Avoid problem with zero-sized linetab
1480 versus malloc/free. From: john@labtam.labtam.oz.au (John Carey).
1481 * core.c (solib_add_stub, core_open): Call SOLIB_ADD inside a
1482 catch_errors() so we can setup the frame regardless of whether
1483 the shared libs work.
1484 * ieee-float.c (double_to_ieee_extended): Get exponent from
1485 right place in little-endian systems. From John Carey.
1487 Thu Aug 15 18:43:57 1991 John Gilmore (gnu at cygint.cygnus.com)
1489 * main.c: Remove unused terminating_signals and catch_termination().
1490 (long_options): Terminate with a zero element.
1491 [Bugfix from Atsuo Kawaguchi <atsuo@hark86.harl.hitachi.co.jp>.]
1492 (gdb_readline): Make call-compatible with readline.
1493 (init_signals): Improve comments re vfork vs. signal.
1495 * utils.c (prompt_for_continue): Use new gdb_readline().
1496 If we prompt for continuation, we don't let CR repeat the previous
1497 command, once we get back to a prompt. It's too easy to keep
1498 hitting CR, expecting "--more--" prompts, and have some long
1499 command start repeating on you.
1501 Tue Aug 13 16:17:56 1991 John Gilmore (gnu at cygint.cygnus.com)
1503 * blockframe.c (frameless_look_for_prologue): Speed up by
1504 calling SKIP_PROLOGUE_FRAMELESS_P if it's defined.
1505 * tm-sparc.h (SKIP_PROLOGUE, SKIP_PROLOGUE_FRAMELESS_P):
1506 Define two variants, one faster.
1507 * sparc-tdep.c (sparc_frame_chain): Use target_read_memory
1508 and return zero, rather than giving an error.
1509 (setup_arbitrary_frame): Initialize the PC in the new frame.
1510 (skip_prologue): Add a second arg saying whether we're just
1511 checking for a frameless function or not.
1513 * core.c (core_open, core_close, core_xfer_memory): Move
1514 section table pointers and bfd* into the target_ops.
1515 (core_open): Allow errors in shared lib reading, etc.
1516 (core_files_info): Describe shared library sections.
1518 * exec.c (exec_open, exec_close, exec_xfer_memory, xfer_memory,
1519 exec_files_info, set_section_command): Move section table
1520 pointers and bfd* into the target_ops.
1521 (add_to_section_table): Add BFD to section table.
1523 * target.c (target_xfer_memory, target_info): Pass target to
1524 xfer_memory and target_info functions.
1527 * gdbcore.h: Move struct section_table.
1528 * target.h: New home of struct section_table.
1530 * solib.c (solib_add): New argument is the target_ops whose
1531 section list is to be added to, if any. Reallocate the
1532 sections in that target to add any that come from shared libs.
1533 (throughout) so_sections renamed to sections.
1534 (solib_xfer_memory): Deleted.
1535 * tm-sunos.h (SOLIB_ADD): Add target argument.
1536 (SOLIB_XFER_MEMORY): Delete.
1538 * core.c, exec.c, inftarg.c, remote-eb.c, remote-nindy.c,
1539 remote-vx.c, remote.c, target.c, target.h: Remove add_syms vector
1540 from target_ops. It's the same on all targets. Add two section
1541 pointers to target_ops.
1543 * stack.c (find_relative_frame): Dump ancient algorithm for
1544 "down", just use handy "next" pointers.
1545 (frame_command): Don't error if there is no stack; let user
1548 * inflow.c (new_tty_prefork, new_tty): New prefork routine
1549 modifies static state in the parent process; new_tty itself
1550 runs in the child and modifies the child's file descriptors
1551 to match the saved static state.
1552 * infrun.c (child_create_inferior): Call new_tty_prefork,
1555 * infptrace.c (child_xfer_memory): Add ignored target arg.
1556 * remote-eb.c (eb_xfer_inferior_memory): ''
1557 * remote-nindy.c (nindy_xfer_inferior_memory): ''
1558 * remote-vx.c (vx_xfer_memory): ''
1559 * remote.c (remote_xfer_memory): ''. Rename from
1560 remote_xfer_inferior_memory.
1562 * main.c (main): Only try to attach "corefile" argument if
1563 it starts with a digit.
1565 * symfile.c (symbol_reloading): New "set/show" variable.
1566 (symbol_file_add): Shorten message about symbol reading.
1567 (add_symbol_file_command): Merge with add_syms_addr_command,
1568 since this should work on all targets now.
1569 (stop_whining): Default to zero, to shut up complaints
1570 about bad symbol tables on many systems.
1571 (free_named_symtabs): Just exit unless symbol_reloading.
1573 * xm-sun3os4.h, xm-sun4os4.h: Define BROKEN_LARGE_ALLOCA,
1574 and add comment explaining shared library screw.
1576 * source.c: #if defined => #ifdef.
1578 Thu Aug 8 12:23:19 1991 John Gilmore (gnu at cygint.cygnus.com)
1580 * doc/gdbint.texinfo: Improve doc on porting to new OS's.
1582 Tue Aug 6 17:16:15 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1584 * doc/rdl-apps.texinfo: provide default readline-appendix finder
1585 (doc/Makefile knows how to make one for local config)
1587 * Makefile.in: use doc/Makefile for doc targets
1589 * doc/Makefile: GDB documentation now has its own Makefile
1590 doc/refcard.tex: renamed from "gdbrc.tex"
1591 doc/.Sanitize: add Makefile; recognize renamed refcard.tex
1592 doc/gdbint.texinfo: add markup in "Cleanups" chapter
1595 Fri Aug 2 00:13:06 1991 John Gilmore (gnu at cygint.cygnus.com)
1597 * values.c (baseclass_addr): When reading target memory, use the
1598 length of the basetype, not the upper type. We've only malloc'd
1599 enough space for the basetype, leading to errors in free().
1601 * expprint.c (print_subexp): Print UNOP_MEMVAL of an OP_LONG that
1602 ends up as a function specially, since we know the actual type of
1603 the pointed-to address. This (somewhat) fixes display of
1604 expressions that include misc_function_vector names. Try `cond 1
1605 !strcmp("a","b")' then `i b'.
1607 * infrun.c: Move DO_DEFERRED_STORES from proceed() to resume().
1608 The child can be proceeded from inside wait_for_inferior in
1609 evaluating breakpoint conditions, and DO_DEFERRED_STORES was
1610 getting skipped in that case.
1612 * expprint.c (print_subexp): Use filtered output, since the
1613 subroutines we call use it, otherwise the output is horribly
1614 mangled, since output of wrappable stuff comes out late.
1616 * Makefile.in: Bump VERSION to 3.98.1
1618 * infrun.c (child_create_process): Use execlp to find the
1619 shell to exec our target program. This requires some fiddling
1620 with `environ' since there is no execlpe().
1622 Thu Aug 1 15:35:17 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
1624 * Makefile.in, doc/gdbrc.tex, doc/rc-* (new files):
1625 Minor rearrangement of refcard permits two new make targets--
1626 gdbrc.dvi DVI output for refcard, using CM fonts
1627 gdbrc.ps PostScript refcard, using PS fonts
1629 Wed Jul 31 16:46:21 1991 John Gilmore (gnu at cygint.cygnus.com)
1633 * TODO, Projects, WHATS.NEW, README: Update for gdb-3.98.
1634 * Makefile.in (gdb-all.texinfo): Avoid touching file if M4 dies.
1636 Wed Jul 31 16:35:58 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1638 * doc/gdb.texinfo: last changes for release.
1639 Minor typo and formatting fixes; incorporated most fixes remaining from
1640 filed mail commenting on earlier drafts.
1642 Added warnings: pipes don't work in run command;
1643 conditions are converse of assertions;
1644 step over fn without debug info goes to next fn;
1645 vars may have "wrong" values near fn entrance, exit
1647 Added example from Kingston on printing repeated nonadjacent values
1649 Added explicit mention that in Emacs gdb mode C-c and C-z are like
1650 shell mode for signals
1652 Renamed "Stepping and Continuing" to "Continuing and Stepping" so it
1653 doesn't sound so much like its parent "Stopping and Continuing"; also
1654 moved entries on continue to top of section, so they don't get lost.
1656 Improved installation directions in appendix, added manual formatting
1659 Tue Jul 30 17:26:39 1991 John Gilmore (gnu at cygint.cygnus.com)
1661 * configure.in: Remove xm.h and tm.h even if we aren't linking
1662 new ones, so "./configure sun4; ./configure none" does the right
1663 thing. Assume that alldeps.mak and depend are already built in
1664 srcdir, and avoid running "make" (particularly "make depend",
1665 which involves "gcc") from inside configure. Build Makefile
1666 directly rather than building Makefile.conf first.
1667 * configure: Regenerate with above changes.
1668 * Makefile.in: Use $(BISON) to find bison. Roll VERSION
1669 to 3.98. Revise gdb.tar.Z procedure to produce a file
1670 called gdb-$(VERSION).tar.Z but which unpacks into a
1671 directory called "gdb". Move non-source files out of
1672 $(SFILES_SUBDIR). Pretty up alldeps.mak with comments.
1673 (depend): Don't try to do "gcc expread.y".
1674 (expread.o): Update dependencies by hand.
1676 Mon Jul 29 15:21:09 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1679 Fixed a variety of small typos that prevented info from formatting
1680 cleanly; altered too-long heading for GPL Appendix, as discussed
1681 w/RMS; Changed date on cover to July 91.
1683 Fri Jul 26 13:20:02 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1686 (1) Applied some fixes due to comments from Larry Breed (easier ones
1687 through chapsec 5.2)
1688 (2) Eliminated use of @footnote---had my doubts about it anyways, and
1689 it's broken in latest texinfo
1690 (3) Introduced *some* use of [] for optional arguments, where
1691 explanation is not simpler by listing cmd w arg and cmd w/out arg
1692 separately. Still not using @deffn.
1693 (4) Dropped in GPL-2. NOTE: one of GPL-2 or texinfo is broken; a
1694 couple of headings are too long. Need patches to texinfo or revision
1697 * Partial update to README (which still needs work for this
1698 release!): (1) use of configure corrected for new script,
1699 (2) "make gdb.dvi" and "make gdb.info" mentioned.
1701 Wed Jul 24 06:44:02 1991 John Gilmore (gnu at cygint.cygnus.com)
1703 * symtab.c (lookup_symbol): Don't complain right off about
1704 no debug symbols; use the misc function vector first.
1705 (list_symbols): Use misc function vector to find symbols
1706 that don't have debug info, and print them.
1707 (find_pc_symtab): Temporarily avoid fatal() when psymtab
1708 PC range doesn't match symtab PC range, as it does on the
1709 MIPS because our symtab reading isn't perfect.
1711 * dbxread.c (dbx_symfile_read): Make warning about
1712 "no debug symbols" slightly nicer.
1714 * source.c (select_source_symtab): If "main" symbol exists,
1715 but decode_line_spec can't find line info, don't just return
1716 a zero; try other source symtabs or give an error.
1718 * mipsread.c (parse_partial_symbols): Sort the psymtabs by
1719 their low addresses first, then rip through fixing high addrs.
1721 * ns32k-opcode.h (sfsr): Bugfix from Rune Nerg}rd,
1722 <runene@ifi.uio.no>.
1723 (NS32K_SVC_IMMED_OPERANDS): Reverse the #ifndef.
1725 Tue Jul 23 18:52:43 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1727 * Minor, mostly mechanical, cleanup of doc subdir for clean
1728 makeinfo'ing and TeXing; also ensured gdb-all.texinfo (post-m4)
1729 and gdb.info (post- texinfo2 makeinfo) generated for distribution.
1731 Sun Jul 21 03:54:52 1991 John Gilmore (gnu at cygint.cygnus.com)
1733 Mostly MIPS and general symbol-reading fixups.
1735 * doc/gdbint.texinfo: Add documentation on symbol-reading
1738 * mipsread.c: Remove kludges around #include "ecoff.h".
1739 Remove redefinitions of a_magic, etc, no longer used.
1740 (parse_symbol, ): Convert "Internal:" printfs to complain()ts.
1741 Fix global overview comments to match symfile.c protocol.
1742 (mipscoff_new_init): Eliminate cur_hdr if we have one.
1743 (mipscoff_symfile_read): Eliminate unused code. Avoid
1744 sorting all the symtabs, when all we have read here is psymtabs.
1745 The symtabs are sorted as they are created anyway. Tell
1746 condense_misc_bunches whether we're mainline.
1747 (psymtab_to_symtab_1): Pass filename when recursing, to make
1748 stack trace more informative.
1749 (parse_partial_symbols): Assume cur_hdr as argument.
1750 (read_mips_symtab): Don't clobber cur_hdr, so it can be freed.
1751 Pass cur_hdr implicitly to parse_partial_symbols. Avoid checking
1752 the TYPE_NAME of char *, since that's done in symfile.c.
1753 (free_numargs, parse_symbol, add_symbol, add_block,
1754 shrink_linetable): Declare these fns void.
1755 (upgrade_type): Convert tree of if's to switch. Clean up
1756 bogus "off == 0" handling with a complaint. Avoid setting
1757 field bitpos and bitsize of array with lower and upper bounds.
1758 Check specified bitsize of elements against their actual type's
1759 bitsize, and complain if different. Complain about unknown
1761 (parse_fdr): Don't assume sizeof(char *) == sizeof (struct *).
1762 (psymtab_to_symtab_1): Print names of subsidiary files that
1763 are being read in. FIXME, we read far too many files. This code
1764 is not the problem, the problem is in parse_fdr where the psymtabs
1766 (cross_ref): Result should indicate that we used one aux entry
1767 normally, or two if we encountered a "next" entry. This used
1768 to leave the caller pointing at the wrong aux entry.
1769 (add_symbol): If overflowed cur_block, reallocate it larger,
1770 chase all pointers to it, and complain(), rather than clobber memory.
1771 (shrink_block): Use xrealloc rather than xmalloc-and-copy.
1772 (new_field): Only allocate one field initially, not two.
1773 Pull ++ out of macro argument. Simplify.
1774 (_initialize_mipsread): Avoid initialization of importd
1775 global_psymbols and static_psymbols.
1777 * symfile.c (psymtab_to_symtab): Depend on XXX_psymtab_to_symtab
1778 to properly set pst->symtab; avoid searching for it.
1779 (symfile_fns): Improve comments, add a FIXME.
1780 * dbxread.c: Update comments to reflect symfile protocol.
1781 (read_ofile_symtab, end_symtab): Return the symtab.
1782 (psymtab_to_symtab_1): Set pst->symtab.
1784 * coffread.c (coff_symfile_read): tell condense_misc_bunches
1785 whether we're mainline.
1787 * symfile.h (sym_fns): Remove unused sym_discard member.
1788 * coffread.c, mipsread.c, dbxread.c: Remove XXX_symfile_discard.
1790 * mtrace.c (mtrace): Take effect if mallwatch is set, even if
1791 the environment variable is not.
1792 * infcmd.c (finish_command): Use filtered printfs.
1793 * cplus-dem.c: Add struct tags to a few unnamed structs.
1794 * valops.c (value_coerce_array): Improve comments.
1795 * valprint.c (type_print_varspec_suffix): Print array size only
1796 if greater than zero.
1797 * m88k-tdep.c: Shift some lines left by one space, that had
1798 apparently been trashed at some point.
1799 * TODO: More things to do, a few got done.
1801 Thu Jul 18 22:46:05 1991 John Gilmore (gnu at cygint.cygnus.com)
1803 * symtab.h (LOC_EXTERNAL): Eliminate in favor of LOC_STATIC.
1804 (ldsymoff, ldsymlen, globals_offset, statics_offset): Improve
1806 * dbxread.c (read_dbx_symtab): LOC_EXTERNAL -> LOC_STATIC.
1807 * expread.y, findvar.c, symmisc.c: Ditto.
1808 * printcmd.c (address_info): Update printed forms of LOC_
1809 symbols. Elim LOC_EXTERNAL.
1810 (print_frame_args): Keep track of param stack offsets before
1811 re-looking up to find the local register param is kept in.
1813 * mipsread.c: Use <symconst.h> and <sym.h> rather than <syms.h>.
1814 Further integration of mipsread into gdb. Eliminate unused
1815 routines, duplicate declarations. Handle static symbols in
1816 psymtabs as well as external symbols. When reading symtabs,
1817 insert symbols into the correct block (global, static, or a local
1819 (read_mips_symtab, parse_partial_symbols): Don't pass useless
1821 (mipscoff_symfile_read): Don't call select_source_symtab.
1822 (parse_symbol): Use SYMBOL_VALUE_ADDRESS where appropriate,
1823 rather than SYMBOL_VALUE.
1824 (parse_external): Comment clobbering of top_stack.
1825 (parse_partial_symbols): Update comments. Allocate and parse
1826 static symbols as well as external symbols. FIXME, enum values
1827 are not handled in this pass, but should be. Inline new_psymbol.
1828 Use SYMBOL_VALUE_ADDRESS.
1829 (psymtab_to_symtab_1): Read symbols into global static block
1830 by default (until enter some function's local block context).
1831 (sort_blocks): Clean up STATIC_BLOCK as well as GLOBAL_BLOCK.
1832 (destroy_all_symtabs, new_psymbol): Eliminate, unused.
1834 * source.c (select_source_symtab): Select a source symtab
1835 from either the symtabs or, failing that, the psymtabs.
1836 (list_command): Update error message.
1837 (forward_search_command, reverse_search_command): Use getc, not
1838 fgetc, for speed. FIXME, add comment about buffers that die if
1839 overrun by long line.
1841 * values.c (unpack_field_as_long, modify_field): Avoid shifting
1842 by an entire word, which is not portable, if we have a 32-bit
1843 field. (Code in dbxread.c already turns such bitfields, if
1844 aligned, into ordinary ints, but fixing this will help for other
1845 symbol formats and for future changes.)
1846 * core.c (core_open): Handle ANSI const brain death.
1847 * utils.c (vprintf): Fix varargs typo.
1849 Sun Jul 14 00:42:53 1991 John Gilmore (gnu at cygint.cygnus.com)
1851 * findvar.c (find_var_value): Handle &function better.
1852 * TODO: Document work needed on &fn and &array.
1853 * printcmd.c (print_address_symbolic): New arg is the prefix
1854 to print if a name is printed.
1855 (print_address_demangle): Honor "set print address" now.
1856 Use new arg above to improve spacing of output.
1857 * valprint.c (val_print): When printing function pointers,
1858 print symbolic form too.
1859 * breakpoint.c (breakpoint_1): Use new print_address_symbolic.
1861 Mon Jul 8 19:02:46 1991 John Gilmore (gnu at cygint.cygnus.com)
1863 * core.c (memory_error): Reword error msg to mislead less.
1865 * mips-pinsn.c (print_insn_arg 'd'): Print $ with reg name.
1867 * mipsread.c (read_mips_symtab, read_the_mips_symtab,
1868 parse_partial_symbols): Use newer BFD internals (external_filehdr
1869 and external_aouthdr), byte-swap the fields that we care about
1870 before using them, and make the file header data local to
1871 read_the_mips_symtab rather than global.
1873 Sat Jul 6 01:34:15 1991 John Gilmore (gnu at cygint.cygnus.com)
1875 * ns32k-opcode.h (movmw, movmd): Fix opcodes. Bug fix
1876 from Rune Nerg}rd <runene@ifi.uio.no> on 5 Jul 1991.
1878 * main.c (command_line_input): Flush stdout and stderr
1879 before every call to readline. This reportedly fixes a bug
1880 that comes up in Sys V running emacs-gdb and/or xxgdb,
1881 when stdin/out are pipes or sockets.
1883 Thu Jul 4 14:47:06 1991 John Gilmore (gnu at cygint.cygnus.com)
1885 * configure.in, Makefile.in: Avoid rebuilding "depend" as much.
1886 Avoid declaring Makefile dependencies, because GNU Make stupidly
1887 tries to update it if we do.
1889 * coffread.c: Revise for minor changes to bfd internal coff
1892 * configure: If -template= is given a relative path, make it
1893 absolute before recurring in subdirectories.
1895 * configure, configure.in, Makefile.in: Install "configure" script
1896 as replacement for config.gdb.
1897 * config.gdb, Makefile.dist, Makefile.sdir: Remove
1898 * README: Update for configure, mostly. FIXME.
1900 * Add dec3100 as equivalent to littlemips. Indicate in all host &
1901 target config files that they are for the host. When the lines
1902 get copied into the Makefile, this makes it more obvious what's
1905 Mon Jun 24 23:49:07 1991 John Gilmore (gnu at cygint.cygnus.com)
1907 * sparc-opcode.h (trap opcodes): Avoid leading spaces or
1908 tabs, which end up in the disassembler output inadvertently.
1910 Wed May 29 23:01:03 1991 John Gilmore (gnu at cygint.cygnus.com)
1912 Make it compile cleanly in an ANSI GCC2 environment.
1914 * blockframe.c: <stdio.h>
1915 * cplus-dem.c: free takes a void *, ifdef __STDC__
1916 * dbxread.c (read_huge_number): avoid gcc2 bug hoisting calc of
1918 * defs.h (alloca): Avoid doing anything if alloca already def'd.
1919 * stddef.h, stdlib.h: Remove these files.
1920 * symtab.c: Avoid declaring qsort, close.
1921 * symfile.c: Avoid declaring close.
1922 * utils.c (vprintf): Declare "ap" arg as proper va_alist.
1923 * sparc-tdep.c: Avoid including lots of Sun-host-specific files.
1925 Assorted other changes.
1926 * dbxread.c: include "libaout.h", not "liba.out.h".
1927 * printcmd.c (print_frame_args): Set recurse properly for
1928 indentation of struct and array parameters.
1929 * valops.c (value_cast): Allow cast to void.
1930 * infrun.c (resume): If NO_SINGLE_STEP, call machine dependent
1931 single_step() in a target-independent fashion.
1932 * sparc-tdep.c (single_step): Don't call ptrace ourselves, just
1933 set up to be ready to continue. This makes us target independent.
1934 * infptrace.c (child_resume): Remove call to single_step; now
1935 can single step a SPARC target of any kind.
1937 Wed May 22 18:18:24 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
1939 * Makefile.dist, doc/gdb.texinfo, doc/*-m4.texinfo: split up GDB
1940 docn into separate sections---basically chapters, plus two loose
1941 pieces that can be configured to go in different places. This
1942 allows GNU m4 to preprocess the manual without coredumping.
1944 * Makefile.dist: tell TeX where to find texinfo.
1946 Mon May 20 12:15:04 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
1948 * Makefile.dist, doc/gdb.texinfo: respectively create, and use,
1949 the new target "rdl-apps.texinfo" which captures the Makefile
1950 variable that records where to find the Readline libraries.
1952 Sun May 19 05:36:59 1991 John Gilmore (gnu at cygint.cygnus.com)
1954 * tahoe-pinsn.c: #include "tahoe-opcode.h", not "opcode.h".
1955 * tm-tahoe.h (FIX_CALL_DUMMY): Ignore more parameters.
1956 * defs.h (const, volatile): Only define if not already defined.
1957 * Makefile.dist (gdb.tar.Z): Create doc subdir w/out CVS/RCS crud.
1959 * README: Update for release 3.95.
1960 * config.gdb: Don't create readline dir in subdir builds.
1961 * main.c: Include with "..." form for non-system include files,
1962 so "gcc -MM" for "make depend" works.
1963 Include readline files with "...h" rather than <readline/...h>.
1964 * mipsread.c: Include "ecoff.h" rather than "intel-coff.h".
1966 * coffread.c: Undo minor damage done by Rich Pixley. Use
1967 different internal and external representations of COFF
1968 data structures. Use new BFD routines for swapping them in and
1970 * symfile.c (free_named_symtabs): Avoid freeing file names that
1971 are null or empty. Old i960 tools seem to produce files that
1972 claim to have empty names, causing each successive file read
1973 to blow away the previous one.
1974 * sparc-xdep.c (deferred_stores): Repair minor damage by Rich.
1975 Move deferred_stores to top of file, but don't separate its
1976 #define's from its variable. Add commentary.
1977 * Makefile.dist: Fix Rich damage; undo "configure" changes in
1978 favor of keeping the (working) config.gdb. Move readline
1981 Fri May 17 12:49:56 1991 Per Bothner (via gnu at cygint.cygnus.com)

1996 * doc/gdb.texinfo: finished using all RMS comments, save those for
1997 appendices on readline and cmd history (which are in other source
2000 Thu May 16 18:06:05 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
2002 * doc/gdb.texinfo: (1) Updated w/ref to RMS comments through
2003 chapter 9; (2) documented 'break' command's menu mode for
2004 overloaded names, in response to hgs problem report C++ p-31

2012 instructions to "Targets" chapter for generic manuals, while
2013 leaving them up front for manuals specific to specialized
2014 environments; (6) apply fixes from RMS comments through chapter 4.

2037 * gdbint.texinfo: added instructions on generating gdb.info* files
2038 locally for release. These are ordinary info
2039 files, formatted from gdb.texinfo (via gdb-all.texinfo, see
2040 Makefile)---but due to use of texinfo 2, can't count on makeinfo
2041 to generate these, so we distribute them already formatted.
2043 * gdb.texinfo: included full Info node and menu crud (as generated
2044 by C-u M-x texinfo-master-menu using the texinfo-2 elisp code).
2046 * Makefile: updated "gdb.dvi" target to use M4 preprocessor;
2047 put in comments-for-future gdb.info target (one day makeinfo will

2061 * mipsread.c: Rather than keeping count of how many symtabs
2062 and psymtabs we have, for sorting purposes, count them when

2090 and memory_remove_breakpoint, no longer used. (Suggestion of
2093 * Makefile.dist: use ${subdir} in paths of BFD and LIBIBERTY,
2094 to make it easier to interface to "configure"'d libraries.

2490 before returning locals or slocals.
2492 * i386-tdep.c (i386_follow_jump): Do not add data16 to pos in

2524 tm-sun3.h: Define TARGET_SUN3.
2526 * utils.c: Use CPLUS_MARKER not '$'.
2528 * cplus-dem.c: Use CPLUS_MARKER not '$'. If CPLUS_MARKER isn't
2529 defined, define it to '$'.
2531 * arm-opcode.h: New file (same contents as before; it had
2532 just been left out of the distribution for a long time).

2556 Makefile.dist: Add it to $(OBS).
2558 * mipsread.c [!CMUCS]: #include <syms.h>.
2560 * mips-xdep.c (fetch_core_registers): #if 0 out the whole function.
2562 * Move read_memory_nobpt from mem-break.c to breakpoint.c.

2602 * inftarg.c (child_open), remote-vx{,.68}.c (vx_proc_open):
2603 New function to give correct error message.
2605 Thu Apr 11 17:19:41 1991 Jim Kingdon (kingdon at cygint.cygnus.com)
2607 * target.h: Add to_doc and target_preopen.
2608 target.c: Add target_preopen and target_command.
2610 (add_target): Call add_cmd and mess with targetlist->doc.
2611 core.c, exec.c, remote-eb.c, remote-nindy.c, remote-vx.c,
2612 remote-vx.68.c, inftarg.c, remote.c: Add doc field to target struct.
2613 Call target_preopen from open routine.

2632 Thu Apr 18 18:08:30 1991 John Gilmore (gnu at cygint.cygnus.com)
2634 * symfile.h (free_named_symtabs): Rename from free_named_symtab.

2636 free_named_symtabs): Move these routines from symmisc.c.
2637 * symmisc.c (same): same.
2638 (free_symtab): Make non-static.
2639 * symtab.h (free_symtab): Declare as exported void fn now.
2640 * dbxread.c (end_symtab, end_psymtab): Change comments.
2641 (initialize_dbxread): Call dbx_new_init() in case the first
2642 command is add-symbols.
2643 * target.c (dummy_target): Permit add_syms_addr_command.
2645 Sat Apr 13 14:46:07 1991 John Gilmore (gnu at cygint.cygnus.com)
2647 Permit symbols to be superseded when new symbol files have
2648 been read in, particularly for VxWorks.
2650 * dbxread.c (read_dbx_symtab): Allow N_SOL to cleanly take us back
2651 to the main file, as well as to include files. Also, put global
2652 functions into the global psymtab, to make "i fun" work.
2653 (end_psymtab): Free named symtabs and psymtabs for a file, once a
2654 new psymtab for it has been read.
2655 * coffread.c (end_psymtab): Free named symtabs and psymtabs for
2656 a file, once a new symtab has been read for it.
2657 * mipsread.c: FIXME. We need to do the same for MIPS, but it
2658 looks harder to determine the top-level block before it's been
2659 queued to the psymtab list.
2661 * symfile.c (symbol_file_add): Use filtered printing and wrap it.
2662 If we have wiped out any old symbol tables, clean up at end of
2664 (symbol_file_command): Don't reference symfile_fns if it's zero.
2666 * symtab.h (GLOBAL_BLOCK, STATIC_BLOCK, FIRST_LOCAL_BLOCK): New
2667 defines for the blocks of a blockvector that contain global and
2668 file-static symbols and the first of the smaller scope contours.
2669 * symtab.c (lookup_symbol, find_pc_symtab, find_pc_line,
2670 decode_line_1, make_symbol_completion_list): Use the above.
2671 * coffread.c (end_symtab, patch_opaque_types): Ditto.
2672 * dbxread.c (end_symtab): Ditto.
2673 * expread.y (block): Ditto.
2674 * mipsread.c (throughout): Ditto.
2675 * symmisc.c (free_named_symtabs): Ditto.
2677 * symtab.c (list_symbols): Process the first symbol of the
2678 static psymbols list.
2679 (types_info): Restore this function from its untimely #if 0.
2680 It's not perfect, but it is better than nothing.
2681 (_initialize_symtab): Restore "info types".
2683 Thu Apr 11 05:23:19 1991 John Gilmore (gnu at cygint.cygnus.com)
2685 * m68k-stub.c: Remote stub for 680x0's, created from
2686 rem-m68k.shar (which is removed).
2687 * nindy-share/{Makefile,Onindy.c,blout.h,env.h,nindy.c,ttyflush.c}:
2688 Remove RCS log stuff now that we use CVS and it blows our diffs.
2690 Wed Apr 10 14:18:06 1991 John Gilmore (gnu at cygint.cygnus.com)
2692 * symmisc.c (free_named_symtab): Make it work, in its current
2693 kludgy fashion. Change result to indicate if we blew away bkpts.
2694 * dbxread.c (end_symtab): Accumulate result from
2695 free_named_symtab and print warning if we blew user's state.
2696 * symfile.h: free_named_symtab now returns an int.
2698 Mon Apr 8 23:57:43 1991 John Gilmore (gnu at cygint.cygnus.com)
2700 * dbxread.c (dbx_symfile_read): Initialize psymbol list if this
2701 is the first symbol read, even if not mainline.
2702 (dbx_psymtab_to_symtab): symfile might be zero, cope.
2703 * exec.c (exec_ops): Add_syms_addr is valid in our tvec.
2704 (set_section_command): New command ("section xxx yyy" -- should
2705 be renamed to "set section xxx yyy" FIXME) which sets the
2706 base address of a section of the exec file, overriding the
2707 virtual address that BFD reports.
2709 Fri Apr 5 17:14:39 1991 John Gilmore (gnu at cygint.cygnus.com)
2711 * exec.c: Add add_syms_addr_command to exec_ops, so you can
2712 load symbols at any address while examining an exec file.
2714 Thu Apr 4 10:09:35 1991 John Gilmore (gnu at cygint.cygnus.com)
2716 * tm-i386v.h (FLOAT_INFO): Don't define it, since the code
2717 for printing the float info is host-dependent, not
2718 target-dependent. FIXME.
2719 * i386-pinsn.c: Move #includes to top, remove useless ones.
2720 * i386-tdep.c: Don't bother including <.../reg.h> since we
2721 don't use it (and it doesn't exist on host systems).
2723 * ieee-float.c (ieee_extended_to_double): Convert NaN to Inf.
2724 Convert negative numbers properly.
2725 (ieee_test): Make numbers really random; fix format arg.
2727 * infcmd.c (attach_command, detach_command): Don't repeat on CR.
2728 * core.c (core_detach): Unpush core_ops, which might not be on
2729 top. We used to just pop the top, which broke things. Don't
2730 need dont_repeat() any more.
2731 (core_file_command): Psst! Don't repeat it.
2732 * remote-nindy.c (nindy_detach): Don't need dont_repeat() now.
2733 * expprint.c (print_subexp): Avoid switch fallthru on
2734 BINOP_ASSIGN_MODIFY, so we can print += and such.
2735 * frame.h: Fix typo.
2736 * inflow.c (kill_command): After killing inferior, print our
2737 current frame in the core file, if we have one.
2738 (generic_mourn_inferior): When inferior dies, either select
2739 the current frame (in the new target, e.g. core file), or
2740 set both the current and selected frames to NULL.
2742 Changes from Peter Schauer.
2744 * infptrace.c: Avoid <sys/ptrace.h> on USG.
2746 * Make all file names fit in 14 characters (sigh and damn!):
2747 mv hp300hpux-xdep.c hp300ux-xdep.c
2748 mv symmetry-xdep.c symm-xdep.c
2749 mv symmetry-tdep.c symm-tdep.c
2750 mv convex-opcode.h convx-opcode.h
2751 mv tm-vxworks960.h tm-vx960.h
2752 mv tm-vxworks68.h tm-vx68.h
2753 mv Makefile.srcdir Makefile.sdir
2754 mv gdb-int.texinfo gdbint.texinfo
2755 mv remote-sa.m68k.shar rem-m68k.shar
2756 mv remote-multi.shar rem-multi.shar
2757 * Makefile.dist, README, config.gdb, convex-pinsn.c,
2758 tconfig/symmetry, tconfig/vxworks960, tconfig/vxworks68,
2759 xconfig/hp300hpux, xconfig/symmetry: Change names to shorter
2762 * command.c (user_info_1, user_info): New command for listing
2763 the user-defined commands.
2765 Wed Apr 3 15:00:26 1991 John Gilmore (gnu at cygint.cygnus.com)
2767 * dbxread.c (really_free_pendings): Clear file_symbols
2768 and global_symbols after freeing them; otherwise, running
2769 this function twice (if it appears twice on the cleanup
2770 chain), we try to free things twice.
2772 * dbxread.c (read_dbx_symtab): Calculate end_of_text_addr
2773 based on text_addr (the address of text in core), not on addr (the
2774 offset between text in the .o file and in core). This change
2775 is from Peter Schauer.
2777 * main.c: Define ALL_CLEANUPS as a cast of zero.
2778 (return_to_top_level): Use it.
2779 (main): Do all cleanups after each command run as part
2780 of the gdb startup sequence. Also do all cleanups before
2781 entering the command loop, and every time we exit the command
2782 loop and reenter. Before, the cleanups from the startup sequence
2783 were being left undone until the first error!
2784 (command_loop): Rename do_nothing cleanup to command_loop_marker
2785 so we can see it easily when examining the cleanup chain.
2786 (init_signals): Add another do_nothing for signal handling.
2787 (quit_command): Only try to kill target if it has execution.
2788 Problems in the target stack got us into a state where
2789 inferior_pid was nonzero but none of the targets had execution.
2790 In this state you couldn't exit gdb.
2792 * dbxread.c: Two changes from Peter Schauer.
2793 (echo_command): Fflush output after an echo command.
2794 (show_history): Pass all args to cmd_show_list.
2796 * utils.c (init_malloc): Call mtrace to turn on tracing
2797 if the environment variable MALLOC_TRACE is set to a file name.
2798 * mtrace.c: Add source file which provides a log of every malloc,
2799 free, and realloc to a trace file.
2800 * mtrace.awk: Add source file which analyzes the trace file.
2801 * Makefile.dist (GNU_MALLOC, MALLOCSRC): Add mtrace.{c,o,awk}.
2802 (VERSION): Roll to 3.94.3.
2804 * breakpoint.c (breakpoint_1): Add a space to "i watch" output.
2805 (check_duplicates): Don't bother with watchpoints.
2806 (set_raw_breakpoint): Comment about danger of this routine.
2807 (watch_command): Parse and eval all args before calling
2810 * solib.c (find_solib): Avoid error in referencing memory to
2811 see if any more shared libraries have been added. This is
2812 particularly useful if the target has terminated. Bug reported
2815 Changes from Peter Schauer <pesrem@regent.e-technik.tu-muenchen.de>
2816 in bringing up 3.94.2 on the Sun-3.
2818 * Makefile.dist: Include CFLAGS in rule for cplus-dem.o.
2819 * breakpoint.c (enable_breakpoint): Check for valid watchpoint
2820 expression (in scope) before reenabling watchpoint.
2821 * signame.c (init_sigs): Add missing declaration of i, fix
2822 sys_siglist declaration.
2823 * source.c (list_command): Fixed range computation to use
2825 * stack.c (backtrace_command): Do not allow command if target has
2826 no stack, print informative error message.
2827 * target.c (target_command): Do not write into command line
2828 because this fails if the target command is used in a user defined
2829 command. [This change was enhanced by gnu to support any-
2830 unique-prefix matching on target names.]
2831 * valops.c (value_struct_elt): Avoid infinite loop on an
2832 erroneous attempt to print the member of function (try p main.p).
2834 Mon Apr 1 17:05:45 1991 John Gilmore (gnu at cygint.cygnus.com)
2836 * expread.y (name_no_typename): Avoid reduce/reduce errors
2837 caused by ambiguity in handling NAME_OR_INT and NAME_OR_UINT.
2838 Since the GDB parser really doesn't use name_no_typename in a
2839 name-only context, the parser can't tell the diff between
2840 names and numbers here. Avoid allowing a name_no_typename
2841 to be a NAME_OR_*INT to resolve the conflict.
2843 Sun Mar 31 20:12:07 1991 John Gilmore (gnu at cygint.cygnus.com)
2845 Bugfixes from Mark Fox (markf@wrs.com) (test=testField.c):
2847 * valprint.c (val_print_fields): bitfield printing didn't handle
2848 byte order. Indirect through a few more fns to cope.
2850 * values.c (modify_field): also cope with byte order.
2852 Sat Mar 23 10:02:21 1991 John Gilmore (gnu at cygint.cygnus.com)
2854 Cleanup for release 3.94.2:
2856 * Makefile.dist: Pull REMOTE_OBS. Fix saber includes for BFD
2857 include files. Roll version to 3.94.2.
2859 * coffread.c (init_stringtab): Read length into unsigned char
2860 array before swapping; don't assume 32-bit longs.
2862 * target.c (target_info): Don't bother with get_sym_file, just use
2863 the symfile global variable.
2864 * symtab.h, symfile.c (get_sym_file): Delete it.
2866 * dbxread.c (dbx_symfile_init): Don't depend on long == 4 bytes.
2867 (define_symbol): Set symbol line number to 0 if not gcc-compiled.
2868 (read_type): Replace one more error() with complain().
2870 * mipsread.c (parse_partial_symbols): Replace printf with complain.
2872 * i960-tdep.c: Fix copyright attribution.
2874 * config.gdb: Quote all backquotes in doublequotes. You can
2875 quote me on that. BSD 4.4 shell found this one.
2877 * infptrace.c (throughout): The third argument to ptrace is an
2880 * infrun.c (wait_for_inferior): When program has terminated, we
2881 have to call target_terminal_ours before we pop that target off
2882 the stack (e.g. before a call to target_kill or
2883 target_mourn_inferior). This fixes problem where a program
2884 terminates, then GDB stops for (tty output) and you have to type
2885 "fg" to the shell to resume it. FIXME: This code for what to
2886 do after termination really should be in normal_stop instead.
2888 * gdbcore.h (read_memory_check): Change declaration; it changed
2891 * terminal.h: Include <sgtty.h> before <sys/ioctl.h>, since in BSD
2892 4.4 prereleases, this avoids a bug in their sgtty compatability
2894 * remote.c: Use terminal.h rather than hand-rolling the same.
2896 * signame.c, signame.h (psignal): Arg is unsigned, not int.
2897 * utils.c (strsave, strstr): Fix arg types.
2898 * valprint.c (val_print): lint
2900 MIPS symbol table support from Per Bothner:
2902 * symfile.c (symtab_fns): Remove initializer table that needs to
2903 be hacked for each new symbol file format supported.
2904 (add_symtab_fns): New function, chains symbol table
2905 handlers into the global list.
2906 (symfile_init): Search this list.
2907 * symfile.h: Add next pointer, declare add_symtab_fns.
2908 * coffread.c (_initialize_coffread): Call add_symtab_fns.
2909 * dbxread.c (_initialize_dbxread): Call add_symtab_fns.
2911 * mipsread.c (psymtab_to_symtab_1): return void instead of (struct
2912 symbol *). Thus, we no longer need the hack to trash
2913 pst->filename. Good, since that hack confused code in symfile.c!
2915 (reorder_symtabs, destroy_all_symtabs): Removed static
2916 all_symtabs, which was used to qsort symtabs in reorder_symtabs.
2917 Instead, the latter now uses a temporary array (stack-allocated
2918 from an obstack, and then freed).
2920 (parse_symbol): Added a hack to fix up BLOCK_{START,END} if they
2921 haven't been set in the outermost stBlock of a procedure. This was
2922 a problem with f77 binaries on Ultrix 4.?.
2924 (new_symtab, new_symbol, new_type): Continue changing code to use
2925 obstacks more and otherwise conform to dbxread internal style.
2926 Made the free_code of symtabs be free_linetable (as in dbxread)
2927 instead of free_contents. This implies memory leaks when reading
2928 a new symbol table, until the conversion is finished. Did change
2929 (struct symbol) and (struct type) to be allocated on the
2930 symbol_obstack. Blocks and blockvectors are among the things
2933 * mipsread.c (parse_partial_symbols, parse_fdr): It hasn't been
2934 tested much, but it solved one problem (reported by Meissner), and
2935 cleans up some other things. The problem happened when an
2936 included file contains actual code (functions) and not just
2937 definitions. The mips coff is a little inconvenient there, since
2938 it may cause a procedure to be mapped to the wrong psymtab.
2940 * mips-tdep.c (heuristic_proc_desc): Minor cleanup.
2941 * mips-xdep.c (fetch_core_registers): Minor cleanup. FIXME,
2942 this will need work for the new core paradigm.
2944 Opcode patches from the net:
2946 * mips-opcode.h: fix incorrect disassembly of the mfc1, cfc1, and
2947 ctc1 instructions. Also, the cvt.d.w and cvt.s.w instructions were
2948 missing altogether - they are added here. From Bruce Bauman.
2949 * mips-opcode.h: The low mask for C0 instructions was too small.
2950 From Garrett Lau. I modified the fix to check the entire 32-bit
2953 * ns32k-opcode.h: Fix opcodes for deiw and deid. From Bruce
2956 Thu Mar 21 12:56:46 1991 John Gilmore (gnu at cygint.cygnus.com)
2958 Roll in changes from Per Bothner (Tue, 25 Sep 90 11:11:04):
2960 * dbxread.c (read_type): Pointer subtraction (value_sub in
2961 valarith.c) sometimes failed because the types of the
2962 pointers being subtracted were not identical.
2963 These differed because dbxread.c was allocating pointer types
2964 using dbx_alloc_type+smash_to_pointer_type instead of
2965 lookup_pointer_type. I failed to find a justification for the
2966 former, so I changed it to use the latter. Similarly, I
2967 replaced smash_to_function_type by lookup_function_type,
2968 and smash_to_reference_type by lookup_reference_type.
2970 * mipsread.c (parse_symbol, upgrade_type, parse_procedure,
2971 _initialize_mipsread): corresponding changes.
2973 * symtab.c (smash_to_{pointer,reference,function}_type): eliminate.
2975 * source.c (mod_path): Do tilde_expand on each component of the path,
2976 rather than on the (list of) paths as a whole.
2977 (print_source_lines): Set first_line_listed in addition to
2978 current_source_symtab and current_source_line. If the source was
2979 not findable, after a "dir" command to fix the problem,
2980 a "list" would get the wrong lines.
2982 While I was there... (gnu):
2984 * dbxread.c (read_type): Change error to complaint.
2986 Thu Mar 21 12:56:46 1991 John Gilmore (gnu at cygint.cygnus.com)
2988 First attempt at detailed understanding of symbol table memory alloc.
2990 * dbxread.c (dbx_symfile_read): Free our string table if we
2991 aren't the mainline. Free the "info" struct since we're done with
2993 (init_psymbol_list): Free any previously allocated psymbol lists.
2994 (): FIXME: Should realloc-down the psymbol lists when done reading
2995 the main symbol file?
2997 * symmisc.c (free_symtab): Free fullname field too.
2999 * xm-hp300hpux.h (USG): #undef then #define so Makefile can -D.
3000 (REGISTER_ADDR): Make result type unsigned int.
3002 * xconfig/{i386*,hp300hpux,altosgas,altos}: All config files that
3003 define REGEX must also define REGEX1 (its dependency).
3005 Tue Mar 19 21:28:57 1991 John Gilmore (gnu at cygint.cygnus.com)
3007 * tconfig/i960: No longer works, points you at vxworks960 or
3010 * xgdb.c, XGDB-README: Remove file. Users can get the much
3012 * Makefile.dist: Remove all trace of xgdb.
3014 * breakpoint.c (breakpoint_1): Pass demangle arg to
3015 print_address_symbolic.
3016 (clear_breakpoints): Remove unused function.
3017 (breakpoint_re_set_one): Guts of breakpoint_re_set.
3018 (breakpoint_re_set): Use catch_errors to do them all anyway.
3020 * gdb-int.texinfo (Host versus Target): Add section on what is
3021 a "host" feature versus what is a "target" feature.
3023 * infcmd.c (path_command, path_info): Handle the PATH variable
3024 (object search path) as conveniently as the source search path.
3025 * environ.c (set_in_environ): Set some vars in GDB's environment,
3026 in addition to the child's. PATH, G960BASE, G960BIN for starters.
3027 * source.c (mod_path): New function, from guts of
3028 directory_command, modifies a path. Used by path_command.
3029 (directory_command): Call it.
3030 * defs.h (strsave): Declare.
3032 * utils.c (sevenbit_strings): Add new printing option.
3033 (printchar): Use it.
3034 (strsave): Provide this handy helper routine.
3035 (set_width_command): Rename set_screen_width_command.
3036 (_initialize_utils): "set screen-width" => "set width";
3037 "set screen-height" => "set height"; add sevenbit-strings.
3039 * infcmd.c (do_registers_info): Print floating point registers
3040 in raw hex as well as float format, regardless of whether it is
3041 a "virtual" convertible register.
3042 * tm-sparc.h (PRINT_REGISTER_HOOK): Print every pair of float
3043 regs as a double, just in case it's being used that way.
3044 * values.c (unpack_long): Comment on array/function coercion.
3045 (unpack_double): Argument is in target byte order now. For
3046 integer arguments, just call unpack_long and float the result.
3047 * m68k-tdep.c: include defs.h for "const" handling.
3048 * remote-nindy.c: Use ieee-float stuff.
3049 (nindy_fetch_registers): Unpack double regs to host double, then
3051 (nindy_store_registers): Pack extendeds to host double, flip
3052 around by misusing unpack_double, send as target double.
3054 * tm-vxworks68.h (FRAME_CHAIN): Handle current frame pointer of
3055 zero, as when stopped at the first instruction of a process.
3057 * blockframe.c: Fix filename in comment (param.h => tm.h).
3058 * sparc-tdep.c (skip_prologue): More explicit nudging comments.
3059 * tm-68k.h: Fix typos.
3061 Fri Mar 15 01:09:34 1991 John Gilmore (gnu at cygint.cygnus.com)
3063 Changes from a bringup on the DEC Vax under Ultrix 4.0.
3065 * coredep.c (fetch_core_registers): Pass end-address of register
3066 section to register_addr as expected. Don't call supply_register
3067 if we'd just pass it garbage.
3069 * dbxread.c (read_dbx_symtab): Skip N_NSYMS on Ultrix.
3071 * exec.c (xfer_memory): Use boolean xfer_fn result, not int.
3073 * target.c (push_target, target_info): Cast enums to int for < or
3076 * stack.c (print_frame_info): Identify source file & line
3077 even if we can't print it.
3079 * xm-vax.h (MISSING_VPRINTF): No longer missing in Ultrix V4.0.
3081 Sat Mar 9 10:08:20 1991 John Gilmore (gnu at cygint.cygnus.com)
3083 Clean up IEEE floating point support.
3085 * ieee-float.h: New file.
3086 * ieee-float.c: Write real routines to convert between host
3087 doubles and various target IEEE extendeds.
3088 * m68k-xdep.c: Eliminate assembler code for extended floats.
3089 * xconfig/{3b1,altos,altosgas,hp300bsd,isi,news,news1000,sun2os3,
3090 sun2os4,sun3,sun3os3,sun3os4}: Eliminate use of m68k-xdep.o.
3091 * tm-i960.h, tm-68k.h (REGISTER_CONVERT_TO_VIRTUAL,
3092 REGISTER_CONVERT_TO_RAW): Use ieee_extended_to_double and
3093 double_to_ieee_extended.
3094 * i960-tdep.c: Define ext_format_i960.
3095 * m68k-tdep.c: Define ext_format_68881.
3096 * sparc-tdep.c: Define ext_format_sparc, though unused.
3097 * Makefile.dist (HFILES): Add ieee-float.h.
3098 * inftarg.c: #include "ieee-float.h" for the REGISTER_CONVERT
3101 Obsolete the "coffstrip" program in favor of using BFD's strip.
3103 * nindy-share/coffstrip.c: Remove file.
3104 * nindy-share/nindy.c (coffstrip): Routine to run bfd_strip.
3105 * Makefile.dist: Remove references to nindy-share/coffstrip.c.
3106 * tconfig/nindy960: Remove reference to coffstrip.o.
3108 * Makefile.dist: Roll version number to 3.94.1 (not yet final).
3110 Wed Mar 6 09:56:45 1991 John Gilmore (gnu at cygint.cygnus.com)
3112 * symfile.h: Add symfile_bfd, common between dbxread and coffread.
3113 * dbxread.c: Remove static symfile_bfd.
3114 * infcmd.c (do_registers_info): Add PRINT_REGISTER_HOOK, though
3116 * inftarg.c (child_detach): Pop the child_ops vector if the
3117 detach is successful.
3118 * remote-nindy.c (nindy_create_inferior): Don't push a new
3119 nindy_ops since nindy uses the same one for execution and memory
3121 * core.c (core_ops): Use child_attach and child_create_inferior
3122 rather than default attach and create_inferior functions.
3124 Handle floating point registers in core files.
3126 * sparc-xdep.c (fetch_core_registers): Rewrite for float support.
3127 * sun3-xdep.c (fetch_core_registers): Rewrite for float support.
3128 This version untested since BFD doesn't yet support sun3 core
3130 * hp300hpux-xdep.c: Rewrite fetch_core_registers to new calling
3131 conventions. Fix comments and style. This version has not
3132 been compiled yet, since we have no HP inhouse.
3133 * core.c (get_core_registers): Look for two sections, ".reg"
3134 and ".reg2", and pass both to fetch_core_registers sequentially.
3136 Revise directory path yet again.
3138 * source.c (forget_cached_source_info): Not static any more.
3139 (init_source_path): New default source path is "$cdir:$cwd".
3140 (dir_command): Handle variable arguments ($cdir, $cwd).
3141 (source_info): Print "Compilation directory" rather than
3142 "Originally compiled in" to remind people of $cdir.
3143 (openp): If the path contains $cwd, use current directory.
3144 (open_source_file): If compilation directory is known, replace
3145 first $cdir in path with the compilation directory.
3146 (print_source_lines): Even if we can't print the lines, set the
3147 current symtab and line for future commands like "info source" or
3148 "breakpoint". Also, error message now contains the file name,
3149 line number, and file access error message.
3150 (_initialize_source): Fix help text to describe changes.
3151 * main.c (cd_command): Forget cached source info when we chdir.
3152 * utils.c (strstr): Add simple implementation.
3154 Tue Mar 5 01:41:40 1991 John Gilmore (gnu at fowanton.cygnus.com)
3156 * coffread.c (read_one_sym, init_linetable, init_stringtab):
3157 Byte-swap COFF symbol tables if necessary when reading them in.
3158 Use complain() to replace error message in one spot. Needs
3159 corresponding change in bfd/coff-code.h to make some symbol
3160 swapping routines non-static.
3162 Mon Mar 4 00:53:40 1991 John Gilmore (gnu at cygint.cygnus.com)
3164 Merge changes from Eirik Fuller, for UTek.

3167 * altos-xdep.c, arm-xdep.c, convex-xdep.c, gould-xdep.c,
3168 hp300hpux-xdep.c, infrun.c, inflow.c, infptrace.c, i386-tdep.c,
3169 i386-xdep.c, pyr-xdep.c, mips-xdep.c, remote-eb.c, remote-nindy.c,
3170 remote-vx.c, source.c, standalone.c, stuff.c, sun386-xdep.c,

3172 declarations of errno.
3174 * remote-eb.c: Define B19200 and B38400 as EXTA and EXTB.
3176 * remote-vx.c: Include <sys/time.h> for UTek; Sun gets it via
3177 <rpc/rpc.h> and <rpc/types.h>.
3179 Sat Mar 2 15:47:55 1991 John Gilmore (gnu at cygint.cygnus.com)
3181 * i960-tdep.c (examine_prologue): Add new argument limit,
3182 which stops the scan at the end of the prologue, or at the PC.
3183 This fixes a problem where it walks down into the code for the
3184 user's statements if that code looks like function prologues.
3185 Mark Fox and I have been bouncing this code back and forth, making
3186 small changes to it. Callers changed to match.
3188 Tue Feb 26 01:47:07 1991 Cygnus John Gilmore (cygnus at yuba)
3190 Cleanup for gdb-3.94 release final:
3192 * Makefile.dist: Remove remote-vx.c, remote-nindy.c, and all
3193 the .c files from vx-share and nindy-share, from the various
3194 macros, since they are not found via ALLDEPFILES.
3195 (SFILES): Add tm-i960.h.
3196 (alldeps.mak rule): Break out ALLDEPFILES_MAINDIR and
3197 ALLDEPFILES_SUBDIR. List all the nindy and vxworks subdir files
3199 (TAGFILES_MAINDIR): Change ALLDEPFILES to ALLDEPFILES_MAINDIR.
3200 (gdb.tar.Z): Use ALLDEPFILES_SUBDIR as well as SFILES_SUBDIR.
3202 Mon Feb 25 16:02:35 1991 Cygnus John Gilmore (cygnus at oldman)
3204 * am29k-tdep.c: Add contribution line.
3205 (examine_prologue): Cache information about function prologues in
3206 the misc-function-vector to avoid lots of references over the
3207 serial line while examining instructions.
3209 * core.c (core_close): New function made from cleanup_core.
3211 * core.c, exec.c, inftarg.c, remote-eb.c, remote-nindy.c,
3212 remote-vx.c, remote.c, target.c, target.h,
3213 Update target_ops vector to add attach, close, and load entries.
3214 Use add_syms_addr_command, not add_file_addr_command, for
3215 add_file. Break out close routine from existing code.
3217 * dbxread.c (really_free_pendings): Don't free pending_blocks;
3218 they are in an obstack.
3219 (read_dbx_symtab): Relocate end_of_text_addr in the psymtab.
3221 (define_symbol): Add symbol type parameter; change callers;
3222 pass type parameter to DBX_PARM_SYMBOL_CLASS macro to allow
3223 it to influence the symbol class on the i960.
3224 (define_symbol): Swap LOC_CONST's into target byte order.
3226 * exec.c (exec_close): New function.
3227 (exec_file_command): Call it.
3229 * findvar.c (read_relative_register_raw_bytes): Doc byte order,
3230 Fix byte order of frame pointer.
3231 (read_var_value): Result of 0 if var's value can't be found,
3232 e.g. missing FRAME_ARGS_ADDRESS. Byte-swap LOC_CONST and
3233 LOC_LABEL values to target order. Add LOC_LOCAL_ARG.
3234 (locate_var_value): Use read_var_value and use its lazy address
3235 as the location of the var's value. Lint.
3237 * i960-pinsn.c (next_insn): Add routine from vxgdb for scanning
3240 * i960-tdep.c (arg_address, i960_frame_find_saved_regs): Remove
3241 obsolete Intel versions in favor of vxgdb versions.
3242 (check_host, byteswap, byteswap_val, reorder_val): Eliminate
3243 code dealing with byte order of values, which Intel did in host byte
3244 order rather than gdb-4's target byte order.
3245 (i960_frame_chain_valid): Move to nindy-tdep.c.
3246 (examine_prologue, skip_prologue, frame_find_saved_regs,
3247 frame_args_address, leafproc_return, saved_pc_after_call,
3248 pop_frame): Add vxgdb versions from Mark Fox.
3249 (examine_prologue, frame_struct_result_address): Add code
3250 to deal with the saved value of G13 (struct return address
3252 (frame_args_address): Modify Mark's version to prefer the
3253 saved value over the current value in the topmost frame.
3254 Cache result in the frame info to avoid performance hair in
3256 (print_fault): Add gdb960 code for printing faults.
3257 (_initialize_i960): Actually call check_host.
3259 * ieee-float.c (ieee_extended_to_double, ieee_double_to_extended):
3260 add stub routines. FIXME, these currently just return zero!
3262 * infcmd.c (program_info): Use PRINT_RANDOM_SIGNAL.
3263 (attach_command): Call target_attach, not target_open, now.
3265 * infrun.c (normal_stop): Make global, not static, for vx_attach.
3266 (child_attach): Rename from child_open.
3267 (wait_for_inferior): Use PRINT_RANDOM_SIGNAL. If stop_pc is zero,
3268 don't confuse it with a zero step_resume_break_address.
3270 * inftarg.c (child_detach): Eliminate inferior_pid test.
3271 (child_files_info): Clean up message a bit.
3272 (child_ops): Use child_attach, not child_open, to attach.
3274 * mem-break.c: #ifdef out the whole file if BREAKPOINT is not
3275 set (e.g. on VxWorks or NINDY). Move read_memory_nobpt from
3276 findvar.c to here, since it depends on the contents of the
3277 shadow_contents of breakpoints, but keep if #if 0 since it is
3280 * nindy-tdep.c: New file, contains nindy_frame_chain_valid, moved
3283 * printcmd.c (address_info): Handle LOC_LOCAL_ARG. Lint.
3284 (ptype_command, display_command): Eliminate have_inferior_p and
3285 have_core_file_p in favor of target_has_stack or
3286 target_has_execution.
3287 (print_frame_args): Handle LOC_LOCAL_ARG. Eliminate duplicate
3288 code for actually finding the values of arguments, though we still
3289 keep track of the maximum stack offset for use in printing unnamed
3290 arguments. Handle missing FRAME_ARGS_ADDRESS.
3292 * remote-nindy.c (i960_print_fault): Move to i960-tdep.c.
3293 (struct nindy_regs): Define registers passed to/from nindy.
3294 (nindy_fetch_registers, nindy_store-registers): Translate between
3295 nindy and GDB formats for the registers.
3296 (dcache_init): Statically allocate the cache, since it was being
3297 allocated by a malloc that was never freed anyway.
3298 (nindy_create_inferior): Error, not core dump, if no exec file.
3299 (nindy_before_main_loop): Use target_load, not target_add_file.
3301 * remote-vx.c (net_load): Specify large timeout for load
3302 requests. Allow user to break out with INTERRUPT.
3303 (net_break): Remove useless code, clean up. Change callers.
3304 (parse-args, skip_white_space, find_white_space): Clean up arg
3305 parsing to cope with quoted strings.
3306 (net_wait, net_quit): Never call error, just return status.
3307 (vx_read_register, vx_write_register): Cleanup status checking.
3308 #ifdef the code based on which CPU we are using (960 or 68k),
3309 FIXME, this should be completely general but it isn't yet.
3310 (vx_xfer_memory, vx_resume): Cleanup status checking.
3311 (vx_run_files_info): Improve message.
3312 (vx_load_command): Renamed from vx_add_file_command. Allow load
3314 (net_ptrace): Remove unused routine.
3315 (vx_wait): Adopt code from vxgdb960 to cope with broken
3316 connections to target machine and prompt to disconnect. Remove
3317 debug printouts. Map some EVENT_'s to SIGnals.
3318 (add_symbol_stub, vx_open): Print names of object files we found,
3319 and "ok" if we read their symbols OK. Clarify output in general.
3320 (vx_attach, vx_detach, vx_kill): Add these commands.
3321 (vx_convert_from_virtual, vx_convert_to_virtual): Simplify.
3322 (vx_run_ops): Turn off all_mem, to avoid spurious msg in the
3323 "info files" output, and create_inferior, since we already have
3326 * stack.c (frame_info): Replace Frame_unknown with 0.
3327 (print_frame_arg_vars): Handle LOC_LOCAL_ARG.
3328 (return_command): Pop until the PC matches as well as the FP,
3329 so it works even if the FP is shared with another function,
3330 as in "frameless" or "leaf" procedures.
3332 * symfile.c (load_command): renamed from add_file_target_command.
3333 (add_syms_addr_command): renamed from add_file_addr_command.
3334 (add_syms_command): Stub to call target_add_syms.
3335 (_initialize_symfile): Change command names and descriptions,
3336 add-file => add-syms, and load from alias to its own command.
3338 * target.c (kill_or_be_killed, maybe_kill_then_attach,
3339 maybe_kill_then_create_inferior): Default for attempts to start
3340 a process, if one is already running, is to ask about killing
3341 it and retry if yes.
3342 (upstack_create_inferior): #if-0 it, strata obsolete it.
3343 (push_target, unpush_target, pop_target): to_close() a target
3344 before unstacking it.
3345 (target_info): Renamed from target_files_info.
3346 (_initialize_targets): Rename "i files" as "i target", accessible
3349 * target.h: Improve comments about the target_ vectored routines.
3351 * tm-i960.h: Remove NINDY-specific stuff to tm-nindy960.h.
3352 Convert commenting style to standard GNU style.
3353 (DBX_PARM_SYMBOL_CLASS): allow LOC_LOCAL_ARG's to be recognized.
3354 (SKIP_PROLOGUE): No longer a no-op.
3355 (SAVED_PC_AFTER_CALL): Now handles leaf procedures.
3356 (*_REGNUM): Sort register numbers.
3357 (REGISTER_BYTES, REGISTER_BYTE, REGISTER_RAW_SIZE,
3358 MAX_REGISTER_RAW_SIZE, REGISTER_CONVERTIBLE,
3359 REGISTER_CONVERT_TO_VIRTUAL, REGISTER_CONVERT_TO_RAW): Float regs
3360 are now 10 byte extendeds, not 8 byte doubles.
3361 (FRAME_CHAIN_VALID): Make this config-dependent, since it differs
3362 for nindy versus vxworks targets. FIXME, this should possibly go
3363 in the target vector.
3364 (EXTRA_FRAME_INFO, INIT_EXTRA_FRAME_INFO): Cache both
3365 frame_saved_regs and arg pointer with each frame.
3366 (FRAMELESS_FUNCTION_INVOCATION): New leafproc support.
3367 (FRAME_ARGS_ADDRESS): Use cached result.
3368 (FRAME_ARGS_ADDRESS_CORRECT): New, avoids g14 guessing.
3369 (FRAME_FIND_SAVED_REGS): Change arg to subsidiary fn.
3370 (PRINT_RAMDON_SIGNAL): Call print_fault.
3371 (POP_FRAME): Now works.
3373 * tm-nindy960.h: Break this off tm-i960.h. NINDY-specific
3374 option parsing and startup; STACK_END_ADDR, FRAME_CHAIN_VALID,
3375 BREAKPOINT, and DECR_PC_AFTER_BREAK are here.
3376 (ADDITIONAL_OPTION_HANDLER): use target_load, not
3379 * tm-vxworks960.h: Break this off tm-i960.h. VxGDB specific
3380 startup; DECR_PC_AFTER_BREAK, and FRAME_CHAIN_VALID are here.
3382 * valarith.c (value_subscripted_rvalue): Avoid handling
3383 floats and doubles specially; it gave alignment errors. Lint.
3385 * valops.c (value_of_variable, value_of_this): Error if unknown
3388 * valprint.c (print_floating): Bcopy rather than pointer-deref,
3389 to avoid alignment problems.
3390 (value_print): Handle unknown value address.
3391 (cplus_val_print): Two args are ignored; remove them. Change caller.
3392 (val_print): Use unpack_long rather than pointer-deref.
3395 (unpack_long, unpack_double): Use bcopy rather than pointer-deref
3396 to avoid alignment problems.
3397 (value_being_returned): Error if return value unknown.
3398 (set_return_value): Add bogosity warning, FIXME. *
3400 * TODO: A woman's work is never done.
3402 * Makefile.dist: Distribute REMOTE_OBS into tconfig files.
3403 Separate INCLUDE_CFLAGS for use with lint. Add LINTFILES.
3404 Add ieee-float.o to OBS.
3405 * tconfig/{nindy960,vxworks68,vxworks960}: Include the desired
3406 REMOTE_OBS remote-interface files in the TDEPFILES and TM_FILE.
3407 * tconfig/i960: FIXME. Half-merge, produce warning if config'd.
3409 Changes to generalize the VxWorks RPC protocol slightly, to handle
3410 i960 as well as 68000.
3412 * vx-share/dbgRpcLib.h (VX_SOURCE_STEP): Add.
3413 * vx-share/reg.h: Produce i960 regs #ifdef I80960
3414 * vx-share/xdr_ptrace.c: Skip FPA registers if 960.
3415 * vx-share/xdr_rdb.h: Add SOURCE_STEP struct and xdr decl.
3416 * vx-share/xdr_rdb.c: Add xdr_SOURCE_STEP routine.
3417 * vx-share/xdr_regs.c: Add xdr_regs, xdr_fp_status, xdr_ext_fp
3418 for i960. Change xdr_vectors to xdr_opaques for 68k registers,
3419 so they will move in target byte order rather than network
3420 byte order (happens to be the same).
3422 Mon Feb 25 03:41:44 1991 John Gilmore (gnu at cygint.cygnus.com)
3424 * tm-convex.h (END_OF_TEXT_DEFAULT): Remove #if 0'd block.
3426 Sun Feb 24 00:55:53 1991 John Gilmore (gnu at cygint.cygnus.com)
3429 Add contribution lines to various files, showing where they
3432 * breakpoint.c (break_insn, check_break_insn_size,
3433 read_memory_nobpt): Remove to mem-break.c.
3435 * xm-*.h, param-no-tm.h, tm-29k.h, valprint.c: Change BYTE_ORDER to
3438 * tm-29k.h (STAB_REG_TO_REGNUM): Warn user if symbol table
3439 entry has bad register number. This change is not
3440 tested in this release, FIXME.
3442 * frame.h: Eliminate Frame_unknown in favor of a simple zero.
3445 * value.h: Force value's contents field to be aligned to hold
3446 at least a double or a long long (if supported). This avoids
3447 doing bcopy's in and out of the contents field.
3449 (step_1): Avoid coredump under obscure circumstances when we
3452 * symtab.h (misc_info): Add field to misc function vector for
3453 any kind of cached information the target code desires. AMD
3454 29000 uses this to avoid repeating examine_function_prologue's.
3456 * coffread.c: Lint. Remove static symfile, read_section_header.
3457 core.c (have_core_file_p): Lint: remove.
3458 expprint.c (print_subexp): Lint.
3459 infptrace.c, valops.c, valprint.c: lint.
3461 Roll in changes from vxgdb-5.0.1:
3463 * symtab.h: Comment byte order of each address class. Add
3464 LOC_LOCAL_ARG for frame-relative args (960).
3465 expread.y: Use LOC_LOCAL_ARG where LOC_ARG is used.
3466 symtab.c, symmisc.c: ditto.
3468 * infrun.c (init_wait_for_inferior): Clear stop_signal.
3470 * remote.c (remote_resume): Error if resume with a signal.
3472 * symfile.c (prim_record_misc_function): Clear misc_info.
3473 (fill_in_vptr_fieldno): Check stub type of arg.
3475 * valops.c (value_cast): Avoid looking up names of types whose
3476 name we don't know, to prevent coredump. Sun CC produces typedef
3477 rtx and the name of *rtx is zero...
3479 Mon Feb 18 21:16:25 1991 John Gilmore (gnu at cygint.cygnus.com)
3481 Roll in changes from final AMD 29000 port (Tiemann).
3483 tconfig/am29k: Add COFF_ENCAPSULATE and TARGET=TARGET_AM29K
3484 for ../include/a.out.encap.h. This might not work now that BFD
3485 is separately compiled. Instead, BFD support for encap will have
3486 to translate machine type 29k into the right COFF_MAGIC.
3488 * infcmd.c: Remove references to inferior_pid that aren't used
3489 in actual ptrace calls; use target_has_execution, etc.
3490 (have_inferior_p): Remove function.
3491 (program_info): Print target info rather than "process number";
3492 avoid gratuitous messages unless from_tty.
3493 (run_stack_dummy, finish_command): Set proceed_to_finish.
3494 infrun.c: Remove inferior_pid refs. Decl & init proceed_to_finish.
3495 main.c: Lint. Lose have_inferior_p().
3496 inferior.h (have_inferior_p): Remove, lint.
3497 (proceed_to_finish): Add flag to ask that all regs be saved
3498 by normal_stop, for the few commands that need it, speeding up
3499 serial I/O. Add comments to stop_registers.
3501 * remote-eb.c: Remove newline from breakpoint message we grep
3502 for. Never time out when running the user program.
3506 Wed Feb 13 15:34:40 1991 John Gilmore (gnu at cygint.cygnus.com)
3508 Roll in changes from vxgdb-5.0.1:
3510 * dbxread.c (read_dbx_symtab): If we encounter a "FORTRAN COMMON"
3511 symbol in its raw form, we are processing an unlinked ".o" file.
3512 See if the target environment has assigned it an address, using
3513 target_lookup_symbol (VxWorks does), and enter it into the symtab
3516 * tm-vxworks.h (FRAME_CHAIN, FRAME_CHAIN_VALID): Override usual
3517 68k versions for a simpler version that assumes zero FP at bottom.
3518 Fixes bug of truncated stack reports.
3520 * target.h (target_lookup_symbol): Define this routine's args
3521 and result, finally.
3523 * target.c (nosymbol): Default routine for target_lookup_symbol.
3524 (target_default): Default lookup_symbol and call_function too.
3525 (files_info): Only print has_all_memory warning if a non-dummy
3528 * remote-vx.c (vx_read_register, vx_convert_to_virtual,
3529 vx_convert_from_virtual): If target does not have floating point,
3530 zero register "values", and avoid doing cross-net conversions.
3531 (vx_lookup_symbol): Rename net_lookup_symbol, add to vectors.
3532 (vx_open): Rearrange code that attaches to target and reads
3533 symbols for all loaded modules, to work if some of the modules
3534 are not accessible. Add symbol_stub() and add_symbol_stub()
3535 as callbacks from catch_errors(). Allow connect attempt to be
3536 interrupted painlessly with ^C (FIXME, there are still some bugs
3537 if the interrupt happens during symbol reading.). Print
3538 final message with puts_filtered, since symbol messages are
3543 * main.c (catch_errors): Only print errstring if non-null.
3544 (command_loop): Avoid an ioctl per command to test ISATTY.
3546 * remote-vx.c (net_load): make static; avoid sophomoric msg.
3547 (vx_xfer_memory): Return correct result!
3548 (vx_files_info): Indicate whether target has float or not.
3549 (vx_lookup_symbol): Complain, not error, if target gone.
3550 (vx_open): Print "Connected" msg before disabling immediate-quit.
3551 [FIXME: lookup_symbol and vx_open changes need testing.]
3553 target.c, remote-eb.c, inftarg.c, am29k-opcode.h, target.h,
3554 tm-29k.h, tmm-vxworks68.h, symfile.c, gdb-int.texinfo: Add
3555 contributor lines and update copyrights to 1991.
3557 Changes from an attempted H-PUX host port:
3559 * infptrace.c (PT_ATTACH, PT_DETACH): Handle HP/UX, which
3560 defines PT_ATTACH and PT_DETACH but not PT_KILL.
3561 * remote-eb.c (eb_open): Misplaced endif kills sysv H/PUX.
3562 * remote-vx.c: include <sys/time.h> for HPUX.
3563 * hp300hpux-xdep.c (fetch_core_registers): Rewrite old
3564 "core_file_command" routine to BFD regime. May not work yet.
3566 Attempted port of "gdb-3.4 Van Jacobson xgdb" to modern gdb.
3568 * xgdb.c: Replace X10 version with some VJ version.
3569 (FIXME: Its copyright assignment is not on record.)
3570 * xgdb.c: Update include files to X11R4 (Xaw crud).
3571 (xgdb_display_source, create_text_widget): fix call to
3572 get_filename_and_charpos. Rewack source window stuff for X11R4
3573 (gleaned from include files, and "nm's" of binary libraries, since
3574 I had no doc available).
3575 (append_selection, append_selection_word): Disable with FIXME
3576 since R4 changed interface here.
3577 (create_buttons): Add back the old set of buttons.
3578 (xgdb_create_window): Fix call to XtInitialize (&argc not argc).
3580 * Makefile.dist (xgdb, xgdb-init.c): Update for X11R4 on Suns.
3581 Roll VERSION to 3.94 (not yet final though).
3583 Sat Feb 9 09:46:25 1991 John Gilmore (gnu at cygint.cygnus.com)
3585 * obstack.h (obstack_ptr_grow, obstack_ptr_grow_fast,
3586 obstack_int_grow, obstack_int_grow_fast): Eliminate
3587 cast on left of assignment, which gives MIPS cc fits and is
3590 * sparc-pinsn.c (print_insn): Eliminate 'set' test, subsumed by
3591 F_ALIAS. Use printf, not fprintf, when not passing a file
3593 (compare_opcodes): Check that identical instructions have
3594 identical opcodes, complain otherwise.
3596 * sparc-opcode.h (st %fsr): Fix opcode "lose" mask. This
3597 was reported by Roland McGrath.
3598 (unimp): Only match if exactly zero instruction. (Roland)
3599 (branches and traps): Generate all variations of these
3600 instructions with macros, based on a single call that defines
3601 each condition name and its binary representation.
3602 (set): Turn on alias bit, to avoid test in sparc-pinsn.c.
3604 * valprint.c (val_print_fields): Take, and use, format parameter.
3605 This means that "p/x struct" again prints the elements in the
3606 desired format. Changed callers.
3608 * stack.c (frame_info): Use filtered output, and indicate wrap
3609 points. Remove kludgy formatting designed to avoid line wrap.
3611 * utils.c (wrap_here): If the line is already full (because
3612 we had printed a long indent or long wrapped string), do an
3613 immediate newline-and-indent.
3615 * m68k-pinsn.c (print_insn_arg): Bugfix from
3616 ntmtv!thompson@ames.arc.nasa.gov (Mike Thompson): 'bkpt #0'
3617 instruction is incorrectly disassembled as bkpt #8.
3619 * dbxread.c (end_psymtab): Bugfix from Peter Schauer
3620 <pesrem@regent.e-technik.tu-muenchen.de>: If you want to set a
3621 breakpoint in a *.y file gdb will say Reading in symbols for *.y...
3622 and then will dump core (sometimes). I traced it back to an
3623 uninitialized symfile_name in psymtab_to_symtab.
3624 (const_vol_complaint): Add quotes to message.
3625 (define_symbol): Only believe line number if gcc_compiled.
3626 Avoid allocating symbol if we will not return it.
3628 Add target strata support so that newly established targets go
3629 into their right place in the target stack (e.g. a new exec file
3630 doesn't wipe out the ability to access the running process).
3632 * target.h, core.c, exec.c, inftarg.c, remote-eb.c,
3633 remote-nindy.c, remote-vx.c, remote.c, target.c: Add to_stratum
3634 and initialize it properly in all the targets.
3636 * target.h: Document strata. Change return type of push_target.
3638 * target.c (nomemory): new function for dummy memory access.
3639 (tcomplain): Rename complain, now also used in symfile.c.
3640 (push_target): Push targets within strata. New return value shows
3641 whether new target is on top of stack or not. Always keep dummy
3643 (target_files_info): Ignore dummy target.
3645 * core.c (core_open): Warn user, and skip accessing file, if the
3646 core target is not the topmost target in the stack.
3647 * remote-nindy.c (nindy_create_inferior): Avoid unpush_target, now
3650 * remote-vx.c: Remove vx_prepare_to_store from vxworks memory
3651 target_ops, it doesn't belong there since we have no regs there.
3652 Change name of target from machine => memory to clarify.
3654 Thu Feb 7 16:32:09 1991 John Gilmore (gnu at spiff.cygnus.com)
3656 * Freeze version 3.93 for release.
3658 * Makefile.dist: Handle vx-share and nindy-share subdirs
3659 properly when building gdb.tar.Z.
3661 * symtab.c: lint; add no_symtab_msg to consolidate the messages
3662 printed in various places, so I could change just one copy.
3664 * dbxread.c, coffread.c: Change references to bfd->iostream
3665 to cast to FILE *, now that BFD avoids needing types defined
3666 in other header files.
3668 Tue Feb 5 21:39:35 1991 John Gilmore (gnu at cygint.cygnus.com)
3670 * command.c, dbxread.c, expprint.c, infcmd.c, infptrace.c,
3671 infrun.c, printcmd.c, remote-nindy.c, source.c, sparc-tdep.c,
3672 sparc-xdep.c, symfile.h, symmisc.c, utils.c, valprint.c: Lint
3673 (actually gcc -Wall).
3675 * dbxread.c: Remove first_global_sym, last_global_sym, since
3676 they are never referenced.
3678 * defs.h (baud_rate): Declare.
3679 main.c: Define it, and add the -b option to set it.
3681 * gdb-int.texinfo: Add text on how to define a new host or target
3682 architecture, prompted by Per Bothner's questions about MIPS
3685 * gdb.texinfo: Document "complaints". Change doc of -q since
3686 gdb no longer prints the copyright and blurb if you specify a file
3687 name to be debugged (just like Emacs). Add doc for Nindy-specific
3688 command line flags for specifying target serial port and such.
3689 Update copyright to 1991.
3691 * gdbcore.h: Remove a large mass of now-useless crud, since BFD
3692 has taken over for us the job of ripping up executable files. The
3693 crud caused Per Bothner's port to not compile.
3695 * infrun.c (normal_stop): Avoid printing "Program exited
3696 normally" if we are in batch mode. This allows a GDB which
3697 executes a program on a target system, to behave like a Unix
3698 command (input from stdin, output to stdout, no extraneous
3701 * main.c (main): Allow additional machine-dependent command line
3702 options to be specified with the ADDITIONAL_OPTIONS,
3703 ADDITIONAL_OPTION_CASES, ADDITIONAL_OPTION_HELP, and
3704 ADDITIONAL_OPTION_HANDLER macros. Also allow machine-dependent
3705 processing to occur just before the main loop with
3706 BEFORE_MAIN_LOOP_HOOK.
3707 (main): If a "core file" argument is specified, and it is not a
3708 core file, try it as a process ID to attach.
3709 (symbol_completion_function): Attempt to cope with
3710 "show screen-" TAB, not very successfully. This needs more work,
3712 (batch_file): New function, returns whether we are reading
3713 commands from an interactive tty on stdin, or from somewhere else.
3714 Called by normal_stop since it doesn't get from_tty passed down
3715 to it like many commands do.
3717 * remote-nindy.c: Handle command line options for nindy
3719 (nindy_before_main_loop): Prompt user for tty name if they
3720 don't specify it before getting to the interactive command loop.
3722 * tm-i960.c: Add ADDITIONAL_OPTIONS, etc, to handle -O, -brk,
3723 and -r command line options. Also add hook before main loop
3724 to make it easy to specify a tty.
3726 * TODO: More things to do, one done.
3728 Mon Feb 4 23:57:39 1991 John Gilmore and Mike Tiemann (at cygint.cygnus.com)
3730 * dbxread.c: Make complaint() calls pass pointer, not struct.
3731 Add complaints about badly formatted C++ type information
3732 (const/volatile indicator, and parse errors resulting in
3733 error_type). Fix C++ virtual member fn comment.
3734 (read_struct_type): Avoid bumping pointer if we got a parse
3735 error; this prevents our walking beyond the end of a string.
3736 Terminate loop on null char as well as semicolon.
3737 (process_one_symbol): Fix the LBRAC fix so that it uses the
3738 last previous SLINE, FUN, or SO record's PC address. C++ debug
3739 symbols did not have SLINE records in a useful order compared
3740 to the LBRAC records.
3741 (define_symbol): Handle "catch" records.
3743 * symtab.c (check_stub_type): Added new complain
3744 `stub_noname_complain' and added a consistency check to
3745 keep the debugger from crashing when finishing from an
3746 exception frame. A real fix will be needed later.
3748 Sat Feb 2 10:43:05 1991 John Gilmore (gnu at cygint.cygnus.com)
3750 * infcmd.c (attach_command): Make global.
3752 * Makefile.dist (REMOTE_OBS): Make these compile by default,
3753 but make them easy to comment out. Perhaps later they should
3754 be enabled by what CPU you configure for? FIXME.
3755 (VERSION): Roll to 3.93.
3756 (pinsn.o): Remove rule for obsolete file.
3757 (dbxread.o,coffread.o,mipsread.o): Use ${srcdir} explicitly.
3759 Run down a problem that manifested by printing the wrong function
3760 name in stack traces of read_ofile_symtab. Turned out that the
3761 problem was the SunOS 4.1.1 (and previous) C compiler outputs
3762 the LBRAC symbol with an address in the *data* segment, which
3763 blew our binary search through the blocks.
3765 * dbxread.c: Use the complain() facility consistently to bitch
3766 about problems in the symbol file we are reading.
3767 (finish_block): Add code to check the nesting of the blocks;
3768 complain and Procrust them to fit if wrong.
3769 (make_blockvector): Check the order of the blocks, complain
3770 [but don't cope] if wrong.
3771 (process_one_symbol): ifndef SUN_FIXED_LBRAC_BUG, check LBRAC
3772 symbols to be sure their PC value is greater than the last SLINE
3773 (line number) symbol we've seen, complaining and adopting the
3774 SLINE PC value if wrong.
3776 * symfile.h (struct complaint, complaint_root, complain,
3777 clear_complaints): Add.
3778 * symfile.c (complain, complaint_root, clear_complaints): Add
3779 facility to deal with non-fatal complaints and to regularize their
3781 (symbol_file_add): Clear complaint counters to allow new complaints.
3782 (initialize_symfile): Add 'set complaints' and 'show complaints'.
3784 * dbxread.c (dbx_symfile_read): Remember the address and size
3785 of the string table for the main symbol file, so we won't read it
3787 (dbx_psymtab_to_symtab): Fix the check for main symbol file,
3788 to avoid reading the string table yet again. Lint.
3789 (throughout): Improve filtered output, including word wrap.
3790 (read_range_type): Improve Bothner's fix to handle other types too.
3792 * utils.c: Improve line wrap implementation. Handle unlimited
3793 width by making chars_per_line unsigned.
3794 (puts_filtered): New, easy, function.
3796 * defs.h (puts_filtered): add.
3798 * mipsread.c (compare_symbols, sort_symtab): Remove these fns,
3799 call the identical sort_symtab_syms() in symfile.c instead.
3801 * expread.y: Suggest the `file' command rather than `symbol-file'.
3803 * command.h (enum var_types): Add zinteger for seroable
3805 * command.c (do_setshow_command): Handle var_zinteger. Restructure
3806 nested if's into a switch.
3808 * breakpoint.c (bpstat_print): If bpstat "print" flag is not set,
3809 we did not stop because of a breakpoint (it must have been for
3810 some other reason, like a "stepi"), so don't print anything.
3812 * symtab.c: Include <sys/types.h> all the time. Now that BFD
3813 doesn't include <sys/types.h>, old SunOS's require it for
3816 Sat Feb 2 10:39:15 1991 Per Bothner (bothner@cs.wisc.edu)
3818 A test port of gdb-3.92.6 to the Sony NEWS.
3821 Don't normally link in remote- or vx stuff.
3822 Some of it doesn't compile, and it wastes space for 99% of the users.
3823 Remove reference to no-longer-used HAVE_VPRINTF.
3824 Fixed BFD_DEP typo to BFD_DIR.
3826 Fix cast in arg to bfd_h_getlong.
3827 Make char *prefix be const.
3828 Fix how certain range types are mapped into builtin unsigned int types.
3830 Remove 2 #includes. They cause errors (on Sony, at least),
3831 and aren't needed (they wern't in earlier versions).
3833 print_address_symbolic should never demangle labels
3834 (since it prints *assembler-level* labels).
3836 [This was superseded by the change to printcmd below.]
3839 Add some "volatile" return types to avoid warnings.
3840 If MISSING_VPRINTF add vprintf function and not just macro
3841 (since vprintf is used in printcmd.c).
3843 Unless __GNUC__, use obstack_grow instead of obstack_ptr_grow.
3844 (The latter isn't grokked by some PCC-based compilers.)
3846 [This change is in abeyance, we prefer to fix obstack_ptr_grow.]
3848 Make chunk size of dont_print_obstack 32*4 instead of default 4096.
3849 * nindy-share/coffstrip.c
3850 Added some forward declarations (otherwise, gcc complains
3851 about implicit extern redefined as static).
3853 Sun Jan 20 02:38:19 1991 John Gilmore (gnu at cygint.cygnus.com)
3855 Changes inspired by Per Bothner:
3856 * printcmd.c (print_address_symbolic): Take additional parameter
3857 specifying whether to demangle.
3858 (print_address): Pass in asm_demangle to control demangling.
3859 (print_address_demangle): New fn, takes explicit arg to control
3861 * utils.c: Add new vars demangle and asm_demangle, and let them
3863 (fputs_demangled): If !demangle, just print the argument.
3864 (fprint_symbol): If !demangle, just print raw symbol.
3865 * valprint.c (val_print): Call print_address_demangle rather than
3866 print_address, to cause demangling to depend on the global
3867 rather than assembler-level demangling setting.
3868 * WHATS.NEW, gdb.texinfo: Document.
3870 * main.c (show_command): Show all settings if no arg.
3871 (initialize_main): Make "info set" the same as naked "show".
3872 * command.c (cmd_show_list): Handle prefix commands in the
3873 list, and print the name of the setting as well as its English
3874 description and value.
3876 Allow gdb functions to specify where a line should wrap if it
3877 exceeds the size of a terminal line. Use it to make the output
3879 * utils.c (set_screen_width_command): New fn, mallocs a buffer
3880 of the right size when screen width changes.
3881 (set_screensize_command, screensize_info): Remove #if 0'd fns.
3882 (wrap_here): New fn, indicates a point in the output where we
3883 should wrap the line rather than just letting it overflow at a
3885 (fputs_filtered): Implement wrapping.
3886 (n_spaces): New fn, returns a pointer to N spaces.
3887 (print_spaces_filtered): Use n_spaces.
3888 * defs.h (n_spaces): Declare.
3889 * stack.c (print_frame_info): Wrap with 4-space indent after
3890 fn name and before filename and line number.
3891 * printcmd.c (print_frame_args): Wrap with 4-space indent
3892 before each argument name is printed.
3893 * valprint.c (value_print): Wrap with no indentation before
3895 (val_print_fields): Wrap with indentation relative to nesting
3896 level before each field name.
3897 (val_print): Wrap with nesting indentation before array elements.
3898 * command.c (do_setshow_command): Avoid extra newlines,
3899 wrap with 4-space indent around values printed, end with period.
3900 * WHATS.NEW, gdb.texinfo, gdb-int.texinfo: Document.
3902 * breakpoint.c (breakpoint_1): Implement addressprint for
3903 "info breakpoints" display. Change file name and line number
3904 format to " at file:nnn" rather than " (file line nnn)".
3905 * gdb.texinfo: Document.
3908 Fri Jan 18 07:21:25 1991 John Gilmore (gnu at cygint.cygnus.com)
3910 Frozen for gdb-3.92.6 release.
3912 README, WHATS.NEW: Update for 3.92.6 release.
3914 tconfig/{altos, i386v, i386v32, m88k, umax}: Eliminate
3915 coffread.o from configs since it is now built by default.
3916 tconfig/{3b1, altosgas, arm, convex, hp300bsd, hp300hpux,
3917 i386v-g, i386v32-g, isi, merlin, news, news1000, np1, pn,
3918 pyramid, symmetry, vax, vxworks68}: Eliminate dbxread.o
3919 from configs since it is now built by default.
3921 Makefile.dist: Update for release 3.92.6. Handle files that
3922 have been moved to ../include, ../getopt, or ../bfd. Add
3923 saber.suppress and tests directory. Add config.status to
3924 the release (it will say "none").
3926 coredep.c: Minor formatting fixes.
3928 These changes were made in early December but only checked in now:
3929 * nindy-share/Onindy.c, nindy-share/coffstrip.c,
3930 nindy-share/nindy.c: lint
3931 * nindy-share/nindy.c (ninStopWhy): Don't byteswap the
3932 register values coming back from the target; we store values
3933 in target byte order everywhere.
3935 Wed Jan 16 19:01:37 1991 John Gilmore (gnu at cygint.cygnus.com)
3937 * am29k-opcode.h, am29k-pinsn.c: Add 29050 opcodes.
3939 * valprint.c (cplus_val_print, val_print_fields): New functions,
3940 which print C++ objects. They conspire to avoid printing a
3941 virtual base class more than once, following all the twists and
3942 turns of C++ virtual base rules.
3943 (val_print): Call the above rather than do it by hand.
3945 * symfile.c (symbol_file_add): Only reset symfile_mtime for main
3946 symbol file, not for added files like shared libs. This really
3947 needs to be generalized to a timestamp per file.
3949 * core.c (cleanup_core): Avoid coredump if no core file.
3951 * config.gdb: Accept -host or -target in place of +host or
3954 * coffread.c (find_linenos): Avoid desupported BFD interface
3955 to line numbers. We still read them manually rather than using
3956 BFD's "generic" features.
3958 * gdbrc.tex, threecol.tex: Add GDB reference card and its
3960 Makefile.dist: Add refcard to OTHERS list for creating tar files.
3962 * Makefile.dist: Eliminate use of $< in explicit targets.
3964 * readline/Makefile: Use $< rather than $*.c, which does not
3965 include the VPATH in GNU Make.
3967 * tconfig/i960-bout, tconfig/i960-coff: These are identical
3968 copies of tconfig/i960, added for global configuration
3969 compatability. All i960 versions can read both coff and b.out.
3971 * tm-88k.h: Fix multiline macro that lacked \'s. Remove
3972 COFF_FORMAT and COFF_CHECK_X_ZEROES since these are now handled
3975 * TODO: Think of more things to do.
3977 Wed Jan 2 19:09:29 1991 John Gilmore (gnu at spiff.cygnus.com)
3979 tconfig/{am29k,i960,sun2*,sun3*,sun4*}: Eliminate config
3980 of sdb versus dbx debug symbols. Add kludge for 68881 80-bit to
3981 64-bit float conversion.
3983 tconfig/sun4, tconfig/sun3, xconfig/sun4, xconfig/sun3: Make
3984 equivalent to sun?os4 so global config works.
3986 Wed Jan 2 18:20:51 1991 John Gilmore (gnu at spiff.cygnus.com)
3988 Fix from Eberhard Mattes <mattes@azu.informatik.uni-stuttgart.de>
3990 * main.c: Only declare linesize once; declare pagesize not at
3991 all, since it is never used.
3992 (main): Clear newly allocated line before it is used.
3994 Fri Dec 28 00:13:42 1990 John Gilmore (gnu at cygint)
3996 Further stabilization for the Intel 960.
3998 * Makefile.dist: Parameterize the location of the "include"
3999 and "bfd" directories, as well as "getopt". Add symfile.c.
4000 Link in both dbxread and coffread. Fix up "make depend" to
4001 rewack the locations of include, bfd, and getopt in its output.
4003 * README: Document moving include files, improve some of
4006 * coffread.c: Move common code out to symfile.c. Change
4007 symbol_file_command style interface to use new *_symfile_init
4008 and *_symfile_read interface under BFD. Use BFD internal
4009 info to locate line table, symbols, etc.
4011 * core.c (core_fetch_registers): Rename to get_core_registers
4012 to avoid confusion with fetch_core_registers.
4013 (register_addr): Move to coredep.c, which is already machine
4014 dependent. This leaves core.c pretty clean of dependencies.
4016 * coredep.c (register_addr): Accept this routine from core.c.
4018 * dbxread.c: Move common code (with coffread.c, etc) into new
4019 symfile.c. Each psymtab now contains a pointer to the
4020 format-dependent function that knows how to read it in. Make
4022 (dbx_psymtab_to_symtab): Renamed from psymtab_to_symtab_2.
4023 (process_one_symbol): Add code to complain about a "compiler bug
4024 we muzzle here", if we actually see it.
4026 * eval.c (evaluate_subexp): Insert missing "break" statements
4027 in code that determines whether a variable is an lvalue in
4028 memory, register, or whatever. I detected this via a compiler
4029 bug in which it *almost* mashed out the whole switch statement.
4031 * gdb-int.texinfo: Add minor sections on configuring gdb for
4032 release, and about the README file.
4034 * infcmd.c (registers_info): Fix formatting somewhat. Still
4035 not as pretty as before, but it handles byte swapping.
4037 * remote-nindy.c: If data cache routines are interrupted while
4038 waiting for the remote end, be sure that any uninitialized cache
4039 blocks are on the free list, not on the valid list!
4041 * symfile.h: Flesh out this header file with all the various
4042 routines and variables that have been merged in from dbxread.c
4043 coffread.c, and symtab.c to symfile.c.
4045 * symfile.c: New file, containing code common to dbxread.c,
4046 coffread.c, and some code from symtab.c. All generic code for
4047 reading symbol files should be in here now.
4048 (unrecord_misc_function): Remove unused function.
4050 * symtab.h: Remove file-reading things to symfile.h.
4052 * symtab.c: Remove file-reading things to symfile.c.
4054 * tm-i960.h: Fix FRAME_CHAIN types; define PRINT_RANDOM_SIGNAL
4055 to decode i960 fault types.
4057 * target.h, remote.c, remote-eb.c, remote-vx.c, remote-nindy.c,
4058 target.c: Change type of the "resume" function from int to void,
4059 since its result was never used.
4061 Sat Dec 22 02:51:40 1990 John Gilmore (gnu at cygint)
4063 * main.c: Replace "stupid" with "caution"; you now "set caution
4066 * printcmd.c (print_scalar_formatted): Fix typo in 'g' format
4068 * infcmd.c (do_registers_info): Call val_print to deal with the
4069 byte order of the registers being printed. FIXME, this makes
4070 the formatting of the output uglier.
4072 * infcmd.c (wait_for_inferior): If PRINT_RANDOM_SIGNAL is
4073 defined, call it for signals the debugger doesn't itself use.
4074 The i960 uses this for more detailed fault information.
4076 * remote.c (remote_open): If arg is null, print help rather than
4079 * sparc-xdep.c (register_valid): Avoid declaring size, since
4080 various modules will think of various sizes depending on the
4081 architecture of their tm-file. FIXME, we need protection against
4082 actually entering one of those modules, which would clobber
4083 storage if not for the target architecture compiled into gdb.
4085 * stack.c (up_command, down_command): Always print the frame
4087 (up_silently_command, down_silently_command): New commands
4090 * i960-pinsn.c (reg), i960-tdep.c: Lint.
4092 * i960-tdep.c (i960_frame_chain_valid): Lookup_symbol now takes
4093 more parameters than it used to.
4095 * findvar.c (registers): Increase slop to 256 bytes, which should
4096 protect us against even most RISC machines with large register
4098 (locate_var_value): Move declaration inside related ifdef.
4100 * remote-nindy.c (): Use TIOCSETN rather than TIOCSETP
4101 throughout, to avoid throwing away buffered input from the board.
4102 (nindy_wait): Supply_register takes addr_of_value, not value.
4103 (i960_print_fault): Renamed from i80960_fault.
4104 (nindy_fetch_registers): Avoid have_regs stuff, just get them.
4105 (nindy_store_registers): Avoid regs_changed stuff, just stuff
4107 (nindy_create_inferior): Don't bother to write PC_REGNUM since
4108 we can set the PC in the call to proceed(). Unpush nindy_ops
4109 before pushing it on top, to avoid message to user. Eliminate
4110 commentary from Unix machines that just misleads here.
4111 (reset_command): Fix error message to suggest target command.
4113 Wed Dec 19 11:03:56 1990 John Gilmore (gnu at cygint)
4115 Release 3.92.5 as frozen.
4117 Stabilize the merged release...with help from lint, Saber C,
4120 Everywhere: Add include files needed to declare return types
4121 of functions called.
4123 * gdb.texinfo: Roland Pesch is documenting gdb, glory be!
4125 * breakpoint.h: Add undeclared breakpoint functions, and some
4126 functions for display handling since I couldn't think of a better
4129 * breakpoint.c (insert_breakpoints): Make code for disabling
4130 shared library bkpts more likely to work. It's used when we
4131 rerun a program and stop before the shared library has been
4133 (breakpoint_cond_eval, bpstat_stop_status): Pass arg as int,
4134 cast from pointer, so it squeezes through catch_errors.
4135 (bpstat_stop_status): Fix logic broken some time ago. We now
4136 always create a bpstat if the stop address matches a breakpoint,
4137 even if we don't stop there -- just like the old code used to do
4138 before I got my fingers into it (sigh).
4139 (breakpoint_1): Print "ignore count" after "stop only if"
4140 condition, since that's how it actually works.
4141 (mention): Handle watchpoints as well as breakpoints.
4142 (watch_command): use set_raw_breakpoint and mention to do most
4143 of the work (and initialize all the fields!). Only pass one
4144 arg to parse_c_expression, since that's all it takes.
4146 * command.c (not_just_help_class_command): Rename arg to args
4147 since we ignore "unused argument" warnings on vars named "args".
4148 inflow.c (child_terminal_info): ditto.
4149 infptrace.c (kill_inferior): ditto
4150 main.c (catch_errors, version_info, quit_command, pwd_command,
4151 source_command, dump_me_command, editing_info,
4152 set_history_size_command, set_history, show_history,
4154 stack.c (locals_info): ditto
4155 target.c (target_files_info): ditto
4156 valprint.c (set_input_radix, set_output_radix): ditto
4158 * core.c: Remove old variables for handling core and exec file
4159 sections (data_start, data_end, stack_start, stack_end,
4160 reg_stack_start, reg_stack_end, reg_stack_offset, text_start,
4161 text_end, exec_data_start, exec_data_end, text_offset,
4162 exec_data_offset, data_offset, stack_offset). They're
4163 superseded the more general build_section_table and
4165 (get_exec_file): Mention the `file' command.
4166 (read_memory_check): Rename to memory_error, and only call it
4167 in the case of an actual error.
4168 (read_memory, write_memory): call memory_error.
4169 (core_fetch_registers): Register section name is ".reg".
4171 coredep.c: Remove a bunch of crud now that all this file does
4172 is pull the registers out of a core file.
4173 (fetch_core_registers): Rewrite to actually work, I hope.
4175 dbxread.c: Use a.out.gnu.h, not system a.out, now.
4176 Replace index() with strchr(). Remove all the pre-BFD macro
4177 definitions for accessing the symbol file.
4178 (struct dbx_symfile_info): Encapsulate the information that
4179 dbx_symfile_init needs to pass to dbx_symfile_read in this
4182 (dbx_new_init, dbx_symfile_init, dbx_symfile_read,
4183 dbx_symfile_discard): Rearrange symbol file reading to divide
4184 the format-specific part from the format-independent part,
4185 leaving the format-independent part such as file name expansion
4186 and opening in symtab.c. This replaces
4187 partial_symbol_file_open and partial_symbol_file_read.
4188 Symbol_file_read, add_file, add_file_target_command,
4189 add_file_addr_command move to symtab.c. Pass an explicit
4190 "mainline" flag for when reading the main symbol table, rather
4191 than relying on the offset address to be zero or nonzero.
4193 (dbx_symfile_read): Don't allow void *'s to be printed as
4195 (SWAP_SYMBOL): Use bfd routines to byte-swap the symbols.
4196 (ADD_PSYMBOL_TO_LIST): Make the "function call rather than
4197 macro" debug version really work.
4198 (read_dbx_symtab): Remove unref'd parameter inclink.
4199 Avoid swapping N_SLINE symbols, for speed.
4200 Merge N_TEXT!N_EXT case with the other external symbol
4201 definitions' case. Add comments.
4202 (start_psymtab): Allocate the symfile name in the psymtab on
4203 the psymbol_obstack, rather than using the caller's storage.
4204 (end_psymtab): Only allocate a dependencies list if there are
4206 (psymtab_to_symtab_2): Use BFD when reopening file to read
4207 its symbols for real.
4208 (read_struct_type): Add FIXME comments where it needs work
4210 (read_huge_number): Add FIXME about overflows.
4211 (read_range_type): Add FIXME about comparing a long to 1<<32.
4213 * coffread.c: Minor changes to move things closer to the new
4214 regime with symtab.c and dbxread.c Major work is still needed
4217 * exec.c (exec_file_command): Remove old variables (see core.c
4219 (xfer_memory): If memory transfer is right at the end of a
4220 section, don't lose.
4222 * findvar.c (get_saved_register): If value is in a real
4223 register, LVAL is lval_register, not lval_memory.
4225 frame.h: Declare print_sel_frame and record_selected_frame.
4227 gdb-int.texinfo: New file, for GDB internals documentation.
4228 Very simple, unformatted doc of cleanups is there for now.
4230 gdbcore.h: Remove obsolete variables that described a.out
4231 section addresses and offsets. (See core.c above.)
4232 Declare fetch_core_registers and registers_fetched.
4234 getopt.c: Declare char *alloca(); even on SPARC.
4236 infcmd.c (run_command): Call target_kill rather than
4238 (step_command, next_command, stepi_command, nexti_command):
4239 Declare from_tty parameter even though we don't use it.
4240 (run_stack_dummy): argument BUFFER is a char array, not
4241 a pointer to REGISTER_TYPE.
4242 (finish_command): using_struct_return needed a value *,
4243 not a struct symbol *.
4245 * infptrace.c (child_xfer_memory): To avoid dependency on
4246 where sections are in memory, try PT_WRITE_D and if that fails,
4247 try PT_WRITE_I. Most Unixes don't care which you use.
4249 * infrun.c (step_resume_break_shadow): Change to array to
4250 match other breakpoint shadow storage.
4251 (clear_proceed_status): Pass address of bpstat to
4252 bpstat_clear, not the bpstat itself.
4253 (child_create_inferior): FIXME comment about if the child
4255 (start_inferior): Remove old function.
4256 (child_open): Use target_kill rather than kill_inferior.
4257 (wait_for_inferior): Ditto.
4258 (insert_step_breakpoint, remote_step_breakpoint): Use
4259 new step_resume_break_shadow.
4261 * inftarg.c (child_wait): If all child processes die,
4262 pretend that the one being waited for exited with signal 42.
4264 * main.c (command_line_input): When scanning for comments,
4265 don't coredump on unclosed quotes.
4266 (quit_command): Use target_kill rther than kill_inferior.
4267 (_initialize_main): Rename class_user from "user" to
4270 * printcmd.c (print_command_1): Initialize "fmt" if no format
4271 is specified by the user.
4272 (print_frame_args): Only add to args_printed if we are
4273 actually fetching args from the stack (avoiding undefined
4275 (_initialize_printcmd): Remove bogus \{ from string.
4277 * remote-eb.c (eb_open): Avoid coredump on no argument.
4279 * remote-nindy.c: Bring out of Intel environment into new
4280 target environment. Remove all conditional compilation on
4281 I80960. Massive hacking throughout.
4282 (nindy_xfer_inferior_memory): New routine stolen from
4284 (nindy_create_inferior): New routine pieced together, probably
4285 not quite working yet.
4286 (nindy_ops): New target_ops struct for nindy.
4288 * remote-vx.c: Use write_memory rather than target_write_memory
4289 to get error checking.
4290 (vx_add_file_command, vx_open): Use symbol_file_add rather than
4292 (vx_create_inferior): Use target_terminal_ours...
4294 * signame.c (_initialize_signame): Always initialize, since
4295 we need the table for things other than psignal.
4297 * solib.c (solib_add): Use symbol_file_add, not add_file.
4298 (solib_address): Return boolean result rather than struct
4299 pointer which nobody else knows the type of.
4301 * sparc-tdep.c, valops.c: Use write_memory rather than
4302 target_write_memory, to get error checking.
4304 * stack.c (locals_info, catch_info, args_info,
4305 get_selected_block, frame_command, up_command): Use
4306 target_has_stack, rather than have_inferior_p or
4309 * sun3-xdep.c (fetch_core_registers): Rewrite for new BFD regime.
4311 * symfile.h: New file, defining the interface between the
4312 generic and object-file-specific symbol reading code.
4314 * symtab.c: Move generic symbol-reading interface to symtab.c,
4315 from dbxread.c, coffread.c, mipsread.c, etc. Add symtab_fns
4316 table to map BFD targets to symbol-reading modules in GDB.
4317 Change index to strchr.
4318 (lookup_struct_elt_type): Use error() rather than hand-made
4319 simulations thereof.
4320 (lookup_partial_symbol): Speedup slightly when length == 0.
4321 (symbol_file_add): New function.
4322 (symbol_file_command): Call it.
4323 (symfile_open, symfile_init): New function.
4324 (add_file_target_command, add_file_addr_command): moved from
4327 * target.c (target_command): use target_kill.
4329 * target.h (target_files_info): Don't declare, never called
4332 * tm-sun2.h, tm-sun3.h (STACK_END_ADDR): Use system include
4333 files to determine stack end address.
4335 * valarith.c (value_x_binop, value_x_unop): Change error message
4336 to be more useful. Pass proper argument to value_struct_elt.
4338 * valops.c (value_assign): FIXME comment that long long
4339 bitfields will break here.
4341 * Makefile.dist: Add symfile.h, remote-nindy.c, remote-eb.c.
4342 Update `make saber_gdb' to work better.
4344 * TODO: A woman's work is never done.
4346 * cplus-dem.c, environ.c, inferior.h, infrun.c, inftarg.c,
4347 main.c, obstack.c, printcmd.c, remote-eb.c, remote-nindy.c,
4348 remote-vx.c, remote.c, solib.c, source.c, sparc-pinsn.c,
4349 sparc-tdep.c, sparc-xdep.c, symmisc.c, symtab.c, symtab.h
4350 target.c, terminal.h, tm-sparc.h, tm-sunos.h, utils.c,
4351 valops.c, valprint.c, exec.c: Lint.
4354 Wed Dec 12 23:44:15 1990 John Gilmore (gnu at cygnus.com)
4356 Continuing Intel 960 port merge of GDB.
4358 * Makefile.dist: Merge i960 "nindy-share" files. Rename
4359 malloc.h to gmalloc.h to avoid name conflicts in /usr/include.
4360 Don't ship gdb.dvi in tar file. Link gdb with init.o, not init.c.
4361 Wack over "make depend" so it handles files in subdirectories
4362 vx-share, nindy-share, bfd, and in the current directory.
4364 * blockframe.c (get_prev_frame_info): Remove fatal error
4365 if stack not defined.
4367 * core.c (core_open, core_detach): New functions that handle
4368 the old "core-file" command as "target core" and "detach" instead.
4369 (core_file_command): Call them.
4370 (core_xfer_memory): Use common routine xfer_memory.
4372 * dbxread.c: Include a.out.gnu.h, not system a.out.h.
4373 dbxread now uses bfd for everything but symbol reading itself.
4374 BFD internals are used to drag out the relevant file offsets.
4375 (partial_symbol_file_open): Change args all around for BFD.
4377 * symtab.c: Rename "value" to "val" everywhere, so we can
4379 (symbol_file_command): New command, moved from dbxread.c
4380 and coffread.c. It uses BFD to read the file, then vectors
4381 based on its type, to dbx or coff symbol readers.
4382 * symtab.h: Extern a few vars for symbol_file_command.
4384 * target.h: Breakpoint takes a char * save area, not a char **.
4386 * valprint.c (val_print): When unpacking bitfields, offset
4387 the address in gdb of the value, if it is declared with a shorter
4388 type. Remove the last "runtime kludge test" of host byte order.
4390 * utils.c: Remove old my_bfd_read routine.
4392 * stack.c (frame_info): Use target_has_stack. Print program counter
4393 register's actual name rather than "pc", since it's called the
4394 "ip" (instruction pointer) on the i960 (sigh).
4396 * target.c (target_command): Add command for selecting a target
4397 type and calling its open routine. This is used for initiating
4398 communication with a particular target, in a generic way.
4400 * tm-i960.h: Update for modern gdb. Remove semicolons from
4401 various macros. Handle reading struct return convention, and
4402 error-out attempts to return structs with the "return" command.
4403 Be sure gdb doesn't think we know how to call functions in the
4406 * i960-tdep.c: Rename FRAME_CHAIN_VALID and FRAME_FIND_SAVED_REGS
4407 to i960_xxx in lower case.
4408 (arg_address): Circumvent errors due to LOC_ARG_BLOCK
4409 not being defined yet.

4412 wait_for_inferior during open.
4413 (remote_xfer_inferior_memory): Return length written rather
4416 * remote-vx.c (target_command -> vx_open): Use new generic
4418 * remote-eb.c, inftarg.c, exec.c: ditto.
4420 * infrun.c: Fix comments.
4421 (attach_program -> child_open): Use new generic target command.
4422 (wait_for_inferior): Clear saved register values before target_wait,
4423 so target_wait can set some of them if convenient.
4425 * infptrace.c (fetch_inferior_registers, store_inferior_registers):
4426 Return success indicator, not void.
4427 (child_xfer_memory): Avoid fetching initial word if we'll
4428 overwrite it anyway.
4430 * infcmd.c (attach_command): Use new generic target open routine.
4431 (_initialize_infcmd): Update doc on attach and detach commands.
4432 (do_registers_info): Merge in a byte-order problem as a FIXME
4435 * findvar.c (find_saved_register): Avoid problem in current frame.

4451 Sun Dec 2 16:45:06 1990 John Gilmore (gnu at cygnus.com)
4453 Merge Intel 960 port of gdb, continuing...
4455 * dbxread.c (partial_symbol_file_open, partial_symbol_file_read,
4456 symbol_file_command): Pass from_tty arg to hush 'em up.
4458 * coffread.c (symbol_file_command): Avoid output if from_tty != 1.
4459 Add magic numbers for 960 COFF format.
4461 Fri Nov 30 09:18:20 1990 John Gilmore (gnu at cygnus.com)

4484 Fri Apr 20 13:47:15 PDT 1990
4487 Thu Apr 19 09:54:28 PDT 1990
4488 Add 'reset' command.
4490 Wed Apr 18 09:48:07 PDT 1990
4491 After opening remote tty, wait for 1 second to go by without input
4492 from it before trying to talk to NINDY (fixes problems with the
4493 Heurikon HK80/V960E).
4495 Mon Apr 4 16:33:05 PDT 1990
4496 Some output was not being suppressed in 'batch' mode.
4498 Thu Mar 22 15:31:11 PST 1990
4499 Ask user if old symbol table should be deleted when new file is
4502 Allow user to run a program downloaded before gdb960 was brought up.
4504 Correct "exec-file" help message for i80960 context.

4529 Mon Oct 2 15:56:31 PDT 1989
4531 Added 960CA disassembly support.
4533 To simplify maintenance:
4534 - eliminated use of symblic links on pinsn.c: use i960-pinsn.c
4536 - eliminated opcode.h: incorporates tables into i960-pinsn.c
4537 - moved 960-specific routines from i960-pinsn.c to i960-md.c
4538 - made disassembly interface identical to that in gdmp960.
4542 Wed Nov 28 21:32:48 1990 John Gilmore (gnu at cygint)
4544 * target.h: Allow targets to stack. Add target_has_memory,
4545 _registers, etc. Restructure memory access and "info files"
4546 to walk the target stack.
4547 * exec.c, core.c, inftarg.c, remote.c, remote-vx.c, remote-eb.c,
4548 target.c: Change tables to match target.h.
4549 * inflow.c (child_mourn_inferior): pop child_ops.
4550 (generic_mourn_inferior): Use new has_stack flag.
4551 * infptrace.c (child_xfer_memory): New memory regime.
4552 * inftarg.c (child_files_info): New "info files" regime.
4553 * remote-eb.c: New memory regime, new info files.
4554 * remote-vx.c: New memory regime, new info files. Now use
4555 separate targets for VxWorks attachment to machine, and
4556 actually running a process under VxWorks, since one has
4557 stack & execution & regs and the other doesn't.
4558 * remote.c: New memory regime, new info files.
4559 * sparc-xdep.c (fetch_core-registers): New memory regime.
4560 * target.c: New routines and support for stacked targets,
4561 new memory regime, new info files regime.
4564 Generalize section handling for an arbitrary number of sections,
4565 including use of the new BFD (binary file) library.
4566 * gdbcore.h: Add struct section_table.
4567 * exec.c (build_section_table): Iterate all sections and
4568 record what gdb needs to know about them.
4569 (exec_command): Use it.
4570 (exec_xfer_memory): Use the table.
4571 (exec_files_info): Print the table.
4572 * core.c (core_file_command, core_xfer_memory, core_files_info):
4574 * source.c (find_source_lines): Use bfd_get_mtime.
4575 * dbxread.c: Quick changes to make it compile with new BFD.
4576 * utils.c (error): Avoid using bfd_error in generic routines.

4580 * sparc-xdep.c (fetch_core_registers): Use the .regs info.
4582 * inferior.h (attach_flag): Export.
4583 * infcmd.c (run_command): use new target_create_inferior.
4584 * infrun.c (child_create_inferior): Don't return result.
4585 * Makefile.dist (VERSION): 3.91.4.
4587 Fri Nov 23 28:15:38 1990 John Gilmore (gnu at cygint)
4589 * breakpoint.c (bpstat_num): Handle breakpoints which have
4590 since been deleted, such as temporary breakpoints.
4591 infcmd.c (program_info): ditto.
4593 * core.c (core_file_command): Display the frame where the core
4598 * remote-vx.c (target_command): Merge in target command from
4599 targ-vx.c. A few other cleanups.
4601 * TODO, Projects: Lots more stuff to do...
4603 Fri Nov 23 18:15:38 1990 John Gilmore (gnu at cygint)
4605 Massive changes to wall off the remote-debugging interface
4606 behind a function vector. The port to handle VxWorks targets
4607 is also part of this.
4609 All files: Replace references to renamed functions,
4610 remove references to remote_debugging, remove references to
4611 have_include_file, have_core_file in favor of target_has_stack,
4612 target_has_memory, etc.
4614 * Modularize the breakpoint interface.
4615 breakpoint.h (BREAKPOINT_MAX): New define sets max length of
4616 a breakpoint instruction.
4617 breakpoint.c: struct breakpoint's shadow_contents now sized as
4619 (insert_breakpoints): Vector to target to install breakpoints.
4620 (remove_breakpoints): Vector to target here too.
4621 Remove REMOTE_SA_SPARC kludges and other remote_debugging.
4622 sparc-tdep.c (single_step): Use new breakpoint interface for
4623 the single-step breakpoints.
4624 mem-break.c (memory_insert_breakpoint, memory_remove_breakpoint):
4625 New file, contains routines to insert and remove breakpoints by
4626 reading out the old contents and later replacing them. This is
4627 how ptrace breakpoints work, and many remote systems as well.
4629 * tm-vxworks68.h: New config file, overrides a few things for
4630 Wind River's preferences.
4632 * target.h: New file, for transfer vector used to talk to the
4633 inferior (child, attached, core, exec, remote, etc). All accesses
4634 to the thing being debugged should come through these vectors.
4635 target.c: New file, routines to handle transfer vector.
4636 (various files): Add transfer vectors XXX_ops for the various
4637 targets and pseudo-targets (core files, etc) we support.
4639 * breakpoint.c (bpstat_stop_status): Further explorations of
4640 watchpoints and why things don't work all the time.
4641 (bpstat_alloc): New fn to allocate a bpstat and chain it.
4643 * config.gdb: Only add "source ${srcdir}/.gdbinit" to
4644 the local gdbinit if it doesn't already have it.
4646 * core.c (core_ops): add and install.
4647 Allow core debugging without exec file.
4649 * dbxread.c (free_and_init_header_files): Merge two fns.
4650 (end_symtab): Free named symbol table when a new version comes in.
4651 (read_dbx_symtab): Relocate all kinds of symbols with base
4652 address. First step toward handling different text, data, bss
4654 (add_file_addr_command): Renamed add_file_command.
4655 (add_file_command): Vector to remote handler.
4656 Add "load" as an alias for "add-file" command.
4658 * defs.h: Allow "volatile" to be used in non-ANSI; use it for
4659 non-returning functions.
4661 * exec.c: Add exec_ops, and push it as a target when an exec
4664 * infcmd.c (run_command): Pass executable file name and arg list
4665 separately when starting an inferior. Permit "run" when no exec
4666 file is specified, for VxWorks.
4667 (detach_command): Move to child_detach in inftarg.c.
4669 * inftarg.c: New file. Unix-child-specific routines, and the
4670 child_ops structure.
4672 * inferior.h (registers): Export "registers" as the way for
4673 target dependent register handlers to find gdb's local copy of
4674 the registers. Rename "stop_after_attach" to "stop_soon_quietly"
4675 since it is now used by places that want wait_for_inferior to
4676 handle the grunge but want to see every trap from the inferior.
4678 * inflow.c (create_inferior): Pull out, and merge into infrun.c.
4679 Eliminate remote_debugging hooks in terminal handling.
4681 * infrun.c: Replace start_inferior with child_create_inferior.
4682 Move all the hair of Unix shells and ptrace idiosyncracies into
4683 child_create_inferior, so remote handlers don't have to deal.
4684 Remove running_in_shell. Rename stop_after_attach to
4685 stop_soon_quietly, and use it in a few other places where we want
4686 to just call wait_for_inferior and get control back on the first
4687 trap. trap_expected now never takes a value > 1.
4688 (init_wait_for_inferior): Initialize static vars when a new
4691 main.c (gdbinit): Add new hook for .gdbinit file name, let
4692 it be overridden by config files as GDBINIT_FILENAME.
4693 (DEFAULT_PROMPT): Add new hook for overriding (gdb) prompt.
4694 Both of these are used for VxWorks gdb.
4696 mcheck.c: rename include file "gmalloc.c" to avoid problems
4697 with system include file "malloc.c".
4699 param-no-tm.h: New include file, same as param.h but does not
4700 include the default "tm.h" file. This is used in files where
4701 the target is known, e.g. remote-eb.c or sparc-xdep.c.
4703 param.h: Now just a shell that includes tm.h and param-no-tm.h.
4705 remote-vx.c: New file, VxWorks remote debugging support. Uses
4706 RPC routines that are shared with the target system, in directory
4709 remote.c: Vectorize remote interface.
4711 source.c: Globalize source_path, and make an alias "l" for "list"
4712 since we now have the "load" command.
4714 sparc-xdep.c: Use new param-no-tm.h.
4716 symmisc.c (free_named_symtab): Add new function from Wind River.
4717 However, ifdef it out for now while we think about what it should
4720 tm-sun3.h, xm-sparc.h, xm-sun3.h, xm-symmetry.h: Move
4722 the xm- file, and change its name to CHILD_PREPARE_TO_STORE, since
4723 non-Unix-children handle this with their own code in the target
4726 Makefile.dist: Roll version to 3.92.3. Add vx-share stuff to
4727 source and target lists. Add vx-share to default list of include
4728 directories. Add new files to src and target lists: mem-break,
4729 target, inftarg, remote-eb, remote-vx, targ-vx. Be sure the
4730 ${srcdir} versions of munch and createtags are used.
4732 * valops.c (find_function_addr): Split out of call_function.
4733 (call_function_by_hand): Rename call_function; this function
4734 calls functions in the target by laboriously patching the target
4735 word-by-word with the right stack, args, regs, etc.
4738 Mon Nov 5 17:29:10 1990 John Gilmore (gnu at cygint)
4740 Handle AMD 29000 a bit better.
4742 * remote-eb.c (readchar): Mask received char log to make it readable.
4743 (remote_start): Pass arguments down to executing program.
4744 Make startaddr unsigned.
4745 infrun.c (start_inferior): Accept args, pass them to
4747 infcmd.c (run_command): Pass args down to start_inferior.
4749 * tconfig/am29k-aout, tconfig/am29k-coff: New files specifying
4750 the target object file format.
4751 tm-29k.h: Pay heed to COFF_ENCAPSULATE.
4753 * am29k-pinsn.c (print_insn): Print 0x on hex numbers in disassembly.
4754 am29k-tdep.c (examine_prologue): Better checking of function prefixes.
4756 Sun Oct 7 18:20:45 1990 John Gilmore (gnu at cygint)
4758 * Makefile.dist (VERSION): Roll version to 3.91.9 and freeze.
4759 * TODO: We did a few things, we have more to do though.
4761 * xm-sparc.h (CLEAR_DEFERRED_STORES): Define.

4767 (sparc_frame_find_saved_regs): Simplify and fix what we find.
4768 (sparc_push_dummy_frame): Simplify and fix what we push.
4769 (sparc_pop_frame): Slightly more hair here, deciding whether
4770 we are restoring a saved PC or returning to a return address in %i7.
4771 * sparc-xdep.c (read_inferior_registers): Debug if valid reg is read.
4773 * utils.c (xmalloc, xrealloc): Return type depends on __STDC__.
4774 * symtab.h (xmalloc): ditto, for obstack_chunk_alloc.
4775 * obstack.h (chunkfun): ditto.
4776 * defs.h (xmalloc, xrealloc): ditto
4778 * utils.c (quit): Grab the terminal from the child if necessary.
4780 * inflow.c (term_status_command): Rename to term_info, change
4783 * sparc-pinsn.c (print_insn): Disassembly prefers real instructions.
4784 (is_delayed_branch): Speed up.
4785 * sparc-opcode.h: Add ALIAS bit to aliases. Fix up opcode tables.
4786 Still missing some float ops, and needs testing.
4788 * Support for input and output radixes other than base 10
4789 * defs.h (input_radix, output_radix): Declare.
4790 * expread.y (yyparse, parse_number): Handle changes of input
4791 radix, and ambiguous names-or-numbers in radixes >10.
4792 * printcmd.c (print_scalar_formatted): Print formatted hex
4793 numbers in varying column widths.
4794 * valprint.c (val_print): Use output_format to print scalar ints.
4795 (set_input_radix, set_output_radix, set_radix): Create.
4796 (set_output_radix): Set output_format from output_radix.
4797 (_initialize_valprint): add `set radix' but leave the others off.
4799 * main.c (execute_command): Let stupid questions be turned off.
4800 (_initialize_main): Handle "set stupidity", etc.
4802 * main.c, inflow.c, inferior.h, frame.h, command.c, defs.h,
4803 sparc-pinsn.c, sparc-xdep.c, value.h, valops.c, values.c: Lint.
4805 Tue Oct 2 11:20:02 1990 John Gilmore (gnu at cygint)
4807 * TODO, Makefile.dist, ChangeLog: Freeze for 3.91.8 release.
4808 bfd stuff is still screwed up, but with some manual work, it
4811 * breakpoint.c (bpstat_do_actions): Start over if a command
4812 proceeds the inferior, since the inferior will have stopped and
4813 will need to have its new stop-actions taken care of.
4815 * dbxread.c (read_struct_type): Expression gives Sun3 4.0.3
4816 compiler fits, simplify it.
4818 * gdb.texinfo (directory command): Doc new dir command.
4819 source.c (directory_command): "dir" now puts things on the front
4820 of the path, moves dups up front, and handles multiple names
4821 on the command line, inserting each one in order. It also
4822 blows away cached line and full_filename info.
4824 * stack.c (backtrace_command): Skip "more stack frames follow"
4827 * Change #ifndef HAVE_VPRINTF to #define MISSING_VPRINTF in
4828 xm-convex.h, xm-hp300bsd.h, xm-isi.h, xm-merlin.h, xm-news.h,
4829 xm-np1.h, xm-pn.h, xm-pyr.h, xm-symmetry.h, xm-umax.h, xm-vax.h.
4830 The only odd one was Gould NP1, which had defined vprintf to
4833 * Merge Ted Goldstein <tedg@Eng.sun.com>'s changes for epoch.
4834 printcmd.c (print_command_1): Pass 'inspect' flag down as a global
4835 variable, inspect_it.
4836 valprint.c (print_string, val_print): Use the global inspect_it
4837 to indicate whether to print in Epoch style or normal style.
4839 Mon Oct 1 23:55:26 1990 John Gilmore (gnu at cygint)
4841 * printcmd.c (call_command): add an alias for the "print" command
4842 which runs expressions and doesn't print the result if void.
4843 (print_command_1): implement it.
4845 * command.c: Remove #if 0'd code. Initialize all the fields
4846 in add_cmd (). Rename do_nothing_command to
4847 not_just_help_class_command, and make it externally visible.
4848 command.h: add user_commands to struct.
4849 * main.c (define_command): Don't overload c->function with a char
4850 string as well as a function pointer.
4852 * eval.c (evaluate_subexp): Reinstall tiemann changes to
4853 calling convention of value_struct_elt () that got dropped in
4856 * tm-sparc.h (FRAME_FIND_SAVED_REGS): move to sparc-xdep.c.
4857 sparc-tdep.c (sparc_frame_find_saved_regs): ditto.
4859 * tm-sparc.h (POP_FRAME): replace some constants with defines.
4861 * sparc-xdep.c (store_inferior_registers): defer stores to regs
4862 until a good time (e.g. when we are about to run the child),
4863 saving ptrace calls.
4864 * infrun.c (proceed): handle DO_DEFERRED_STORES.
4865 * tm-sparc.h: define DO_DEFERRED_STORES.
4867 * sparc-xdep.c (store_inferior_registers): when storing float
4868 registers, don't store stack regs too. When storing the SP,
4869 however, DO store the stack regs too. This fixes a bug in which
4870 the dummy frame is not recognized when a call_function finishes,
4871 because its frame pointer (in the stack regs) was never
4873 (read_inferior_registers): Mark WIM and TBR and FPS and CPS valid
4874 even though we don't know how to read them from an inferior.
4875 valops.c (call_function): Comment about storing SP.
4877 * infrun.c (save_inferior_status): Save away the original bpstat
4878 chain so it can be restored later. Install the copied version for
4879 use by whoever saved the status. It will be blow away by
4880 restore_inferior_status, and the original chain restored. This is
4881 important for people who have pointers into the original.
4883 * breakpoint.c, command.h, copying.awk, dbxread.c, defs.h,
4884 findvar.c, frame.h, obstack.h, obstack.c, inflow.c, value.h,
4885 main.c, printcmd.c, sparc-tdep.c, symtab.c, valprint.c: lint
4888 Fri Sep 28 20:32:46 1990 John Gilmore (gnu at cygnus.com)
4890 * Makefile.dist: Roll version to 3.91.8. Add bfd.h and bfdconfig.h
4891 temporarily to the makefile. Add am29k-opcode.h and WHATS.NEW.
4892 Add stuff.c and kdb-start.c to the OTHERS list for tar files.
4894 Fri Sep 28 19:12:12 1990 John Gilmore (gnu at cygint)
4896 * Merge Mike Tiemann's multiple inheritance changes from Sun.
4897 Store the baseclasses in a type struct starting from array element
4898 0 rather than from the unusual array element 1.
4900 dbxread.c: the above.
4901 (virtual_context): Add
4902 Read new debug information about which virtual function table
4903 a virtual function is from, and store it in fn_field.fcontext.
4905 symtab.h: Add fcontextt. Fix baseclass indices. Typo in
4906 TYPE_FN_FIELD_STATIC_P.
4908 symtab.c: the above.
4909 valops.c: the above. Handle pointer casts of object *'s.
4910 (search_struct_method): Add.
4911 (value_struct_elt): First arg is now a pointer to a value, and is
4914 valprint.c: the above.
4915 values.c (value_virtual_fn_field): Add type arg. Handle
4916 offsetting to the proper object when calling virtual fns.
4918 (baseclass_addr): Add valuep arg.
4920 * README: Document the current state of BFD config (missing).
4921 * TODO, ChangeLog, Makefile.dist: Roll version.
4922 * WHATS.NEW: Add summary of changes since 3.5.
4924 Thu Sep 27 16:23:12 1990 John Gilmore (gnu at cygint)
4926 * dbxread.c (read_struct_type): Clear bit vectors whenever
4928 symtab.c (B_CLRALL): define.
4930 * tm-sparc.h (STORE_RETURN_VALUE): Avoid clobbering types by
4931 using == rather than =. Huh... This fixes the dreaded problem
4932 wherein builtin_type_int becomes TYPE_CODE_FLT.
4934 * core.c (info_files): Show the inferior pid.
4936 * config.gdb: Avoid putting "dir" command into .gdbinit. GDB
4937 already knows how to look in the source directory.
4939 * Remove psymtab hair from many places. Remove duplicated code
4940 for searching symbol tables. Hide psymtabs from most places.
4941 Make it fast to get from a psymtab to its symtab.
4943 blockframe.c (blockvector_for_pc): Remove psymtab hair.
4944 coffread.c (psymtab_to_symtab): Rename to psymtab_to_symtab2.
4945 mipsread.c (psymtab_to_symtab): Rename to psymtab_to_symtab2.
4946 dbxread.c: export psymtab_to_symtab, make it work if called N times.
4947 (psymtab_to_symtab): Rename to psymtab_to_symtab2. Initialize
4948 new symtab completely. New psymtabs get symtab pointer
4949 initialized to zero. Remove MI warning printf.
4950 symtab.h: Comments. Add psymtab to symtab pointer.
4951 (PSYMTAB_TO_SYMTAB): New macro.
4952 symtab.c: use PSYMTAB_TO_SYMTAB. Add psymtab_to_symtab and export it.
4953 source.c: use PSYMTAB_TO_SYMTAB. Remove symtab version and
4955 stack.c (backtrace_command): Avoid pre-pass to read symbols, if
4957 (print_frame_info): Avoid special-casing symbols that have not yet
4960 * source.c (open_source_file): Quick path if we have already
4961 located the source file by its full name.
4963 * symtab.c (lookup_symbol): Use find_pc_symtab rather than
4964 find_pc_psymtab. When a name is found in the misc function
4965 vector, search the symbol table for its mangled name, not the
4966 name that the user typed.
4968 * bfd.h: Fix missing comment terminators, make #endifs match.
4970 * valarith.c (value_less): Handle unsigned int comparisons.
4971 Add FIXME about pointer compares, which assume host and target
4972 pointers are the same.
4974 * command.c (do_nothing_command): lint
4975 dbxread.c: lint. Remove sort_syms. Document C++ visibility info,
4976 fix comments on debug symbol format for visibility. Actually set
4977 visibility of symbols.
4978 main.c (echo_command): lint; use <readline/history.h>.
4979 tm-sparc.h (FRAME_FIND_SAVED_REGS): lint
4980 obstack.h (_obstack_blank): Rearrange pointer math to avoid
4981 pointing past end of allocated memory; saber complains.
4982 obstack.h: Declare the external functions that we use.
4983 valarith.h: use <string.h>
4984 solib.c (solib_add): lint.
4986 Fri Sep 21 17:05:19 1990 John Gilmore (gnu at cygint)
4988 * main.c (initialize_main): Default info_verbose to off, now that
4989 symbol reading is fast.
4990 (quit_command): Avoid clobbering exec_bfd while quitting.
4992 * Initial BFD (binary file diddling library) merger:
4993 coffread.c: Change AOUTHDR to struct exe_hdr.
4995 core.c: initialize initialized data at compile time.
4996 (core_file_command): Move from coredep.c, convert to bfd.
4997 (xfer_core_file): Convert to bfd.
4998 exec.c (exec_file_command): use bfd routines.
5000 mips-tdep.c: Remove exec_file_command and friends.
5003 * coredep.c: (fetch_core_registers) Convert core_file_command to
5004 fetch_core_registers.
5005 mips-xdep.c, sparc-xdep.c, sun3-xdep.c: ditto.
5007 * utils.c: (error): Bogus crap, FIXME, to print bfd errors.
5008 (my_bfd_read): More bogosity, which I don't think we call.
5009 (program_name): Remove this atrocity asap!
5011 Wed Sep 19 13:36:41 1990 John Gilmore (gnu at cygint)
5014 values.c: allocate_repeat_value was not clearing the
5015 optimized_out field.
5016 (value_static_field): minor stylistic fix (wrong macro was used).
5017 valops.c (value_struct_elt_for_address): didn't work for C++
5020 * signame.c (_initialize_signame): Initialize signal names once.
5022 * breakpoint.h, command.c, copying.awk, defs.h, environ.c,
5023 exec.c, frame.h, infcmd.c, inferior.h, main.c, munch, sun3-xdep.c,
5024 symtab.h, tm-29k.h, valprint.c, value.h, values.c: Lint.
5026 * remote-eb.c: Support user-settable baud rates on the serial port.
5028 * tm-sun3.h (PREPARE_TO_STORE): fix typo.
5030 Fri Sep 14 13:28:29 1990 John Gilmore (gnu at cygint)
5032 * tconfig/sun3os4: Remove warning about native assembler,
5033 since it also occurs in the xconfig file.
5035 * findvar.c (registers): Allocate some slop after `registers'
5036 to prevent stray accesses from trashing the next variable.
5038 * tm-68k.h (REGISTER_BYTES): Allocate the right number of bytes
5039 on the sun-3, by changing the #ifdef from `sun3' (which is not
5040 defined by cc) to `sun'. Symptom was trashed builtin_type_XXX
5041 vars, which happened to follow `registers' in the executable.
5043 * readline/history.c (history_search): Heed gcc-2's advice
5044 and parenthesize && inside ||).
5046 * am29k-opcode.h, am29k-pinsn.c, am29k-tdep.c, remote-eb.c,
5047 tm-29k.c: Insert FSF copyright headers.
5049 * remote-eb.c: Better comments.
5051 * Makefile.dist: Update to 3.91.6.
5052 * TODO: note PREPARE_TO_STORE problem.
5054 Thu Sep 13 09:52:33 1990 Jim Kingdon (kingdon at cygint)
5056 * stack.c (frame_info): Only use FRAME_FIND_SAVED_REGS if defined.
5058 * remote.c: Wrap the whole file in #if !defined (SPECIAL_REMOTE).
5060 * infrun.c (wait_for_inferior, at end): Don't set up
5061 prev_* if the inferior no longer exists.
5063 * inferior.h (CALL_DUMMY_LOCATION): New macro, to replace
5064 CANNOT_EXECUTE_STACK.
5065 valops.c (call_function): Use it.
5067 * tm-convex.h: Add CALL_DUMMY_LENGTH for use by PC_IN_CALL_DUMMY.
5069 * inferior.h (PC_IN_CALL_DUMMY): New macro.
5070 infrun.c (wait_for_inferior, 2 places): Use it.
5072 * values.c (value_being_returned): Only use
5073 EXTRACT_STRUCT_VALUE_ADDRESS if defined.
5075 * Move PREPARE_TO_STORE from xm-sun3.h to tm-sun3.h to do the
5076 right thing for remote-eb.c.
5078 * sun3-xdep.c: Remove extraneous call to remote_store_registers.
5079 * sun386-xdep.c, hp300hpux-xdep.c, sparc-xdep.c: Ditto.
5081 * blockframe.c: Put get_frame_saved_regs inside #if !defined
5082 (FRAME_FIND_SAVED_REGS).
5084 * findvar.c ({fetch,store}_registers): Check for
5085 REMOTE_{FETCH_STORE}_REGISTER macro.
5087 * findvar.c (get_saved_register): Add argument lval and
5088 change meaning of argument addr.
5089 findvar.c: Change calls to get_saved_register to reflect
5090 new calling convention.
5091 valops.c (value_assign): Use get_saved_register instead of
5092 find_saved_register.
5094 Sun Sep 2 12:40:20 1990 Jim Kingdon (kingdon at cygint.cygnus.com)
5096 * coffread.c (read_one_sym): Make temp_aux an AUXENT, not
5097 an (uninitialized) pointer to one. Use "&" when passing it
5100 Fri Aug 31 22:57:54 1990 Jim Kingdon (kingdon at cygint.cygnus.com)
5102 * coffread.c (getfilename): Use DGUX x_offset and x_name if
5105 * coffread.c (symbol_file_command): Put semicolon after
5107 Put safe_to_init_tdesc_context in #if defined (TDESC).
5108 Put #ifdef TDESCs in 1st column for non-ANSI cpp's.
5109 coffread.c: #include <sys/stat.h>.
5110 (read_coff_symtab): Typo: in_source_files -> in_source_file.
5111 Add missing ')' in check for "lc%" and friends. Remove
5113 Declare read_one_sym() at top of file.
5114 (read_file_hdr): Put in extra #ifdefs so MC68MAGIC and
5115 MC68WRMAGIC can have the same value without causing a duplicate
5118 Thu Sep 13 15:55:36 1990 John Gilmore (gnu at cygint)
5120 * Allow a Makefile to be built without building the
5121 tm and xm file links that screw up builds in subdirectories.
5122 This is done with `config.gdb none', then you can do things
5123 like `make gdb.tar.Z'.
5124 * tconfig/none: Config file for no target system
5125 * xconfig/none: Config file for no host system
5126 * config.gdb: If no TM or XM files are called out by the
5127 host or target file, don't make links for them.
5129 * cplus-dem.c: Add documentation.
5131 * dbxread.c (read_ofile_symtab): Turn a fatal error into a
5132 simple error, so the user's gdb doesn't crash due to some object
5133 file problem (e.g. somebody is rebuilding the file out from under
5136 * printcmd.c (print_address_symbolic): demangle the symbol.
5138 * Makefile.dist (OTHERS): Remove tdesc-lib because it has
5139 Motorola copyrights in it. Make "make gdb.tar.Z" work.
5140 (alldeps.mak): sort and uniq all results from this; duplicates
5141 hose gdb.tar.Z link building. Remove RCS files from
5142 tconfig and xconfig. Add config files for sun386. Add
5143 a few odd files to OTHERS and HFILES.
5145 Mon Sep 10 21:20:24 1990 John Gilmore (gnu at cygint)
5147 * Makefile.dist: Pull solib.c to tconfig/sun?os4.
5148 Roll version number to 3.91.5. Make lint work in bindir.
5150 * README: Document cross-debugging and new file structure.
5152 * blockframe.c: Lint. Include "value.h" to declare read_register.
5153 (find_pc_partial_function): remove duplicate line.
5155 * command.h: Lint. Declare error_no_arg and dont_repeat.
5157 * tm-news.h: Remove inadvertently duplicated stuff.
5159 * mipsread.c: Remove cache_pc_function stuff, now done cleanly.
5160 Clean up usage of misc_function_type. Declare some CORE_ADDRs.
5162 * config.gdb: Allow `config.gdb host target' form. Clean
5163 up previous change that printed bogus messages when you just said
5166 * core.c: #include "command.h" for lint.
5169 * main.c: Remove some casts of enums. Lint.
5176 * printcmd.c (initialize_printcmd): Fix thinko in inspect cmd.
5178 * sparc-tdep.c (isannulled): Take instruction as parameter, don't
5179 read it from memory. This will allow us to save ptrace calls
5180 eventually. Changed caller single_step too.
5182 * sparc-xdep.c (fetch_inferior_registers): Avoid reading regs
5183 that we aren't going to use, saving many ptrace calls, especially
5184 when watchpointing or single stepping. Use some #define's for
5186 (store_inferior_registers): Ditto.
5187 (core_file_command): Use some #define's for constants.
5189 * tm-sparc.h: Add #define's for some register numbers, so we
5190 can eliminate the use of random constants in sparc-xdep.c.
5192 * stack.c (frame_command, print_frame_info, up_command,
5193 down_command) Remove frame_changed, since it
5194 causes a bug and doesn't seem to do anything useful. In some
5195 places it was used as a flag, in others as a stack level (?).
5197 * utils.c: Use MISSING_VPRINTF rather than HAVE_VPRINTF, so the
5198 default is to use the portable (vprintf) version rather than the
5200 * xm-news.h (MISSING_VPRINTF): Add.
5202 * valprint.c (val_print): Demangle fancy vtbl printouts. Lint.
5204 Sat Sep 8 00:24:12 1990 John Gilmore (gnu at cygint)
5206 * Remove stuff that forces -Bstatic linking of gdb, and warnings
5207 about linking debugged programs -Bstatic in the sun?os4 config
5208 files in tconfig and xconfig subdirectories.
5210 * main.c (main): Remove unreached exit(0) now that we exit
5213 * Create TODO file for online bug list. There are too many
5214 "little" bugs to keep track of on paper.
5216 * Change Projects file to refer to bug-gdb@cygnus.com
5217 rather than kingdon@ai.
5219 Fri Sep 7 23:35:15 1990 John Gilmore (gnu at cygint)
5221 * Makefile.dist (VERSION): 3.91.4 now.
5223 * symtab.c (init_misc_bunches): Rename from init_misc_functions.
5224 (condense_misc_bunches): Add sanity check that misc_count is
5225 the same as the number of symbols in the bunch.
5227 * coffread.c: rename init_misc_bunches. Pass an argument
5228 to condense_misc_bunches (a zero).
5230 * dbxread.c (partial_symbol_file_read): Call init_misc_bunches
5231 every time we are called; don't rely on our caller to do it.
5232 (add_file): Remove call to init_misc_bunches.
5234 * mipsread.c: Only warn, don't error, if unknown symbol types.
5235 This keeps an old gdb from falling on its face if it sees newly
5236 extended symbol info. Rename init_misc_bunches.
5238 Fri Sep 7 22:58:15 1990 John Gilmore (gnu at cygint)
5240 * Merge in changes from Per Bothner for DECstations and other
5241 MIPS stuff. The rest is Bothner speaking:
5243 The next message is a merger of Alessando Forin's mips port with
5244 mine. I've tried to use my good if biased judgment to get
5245 the best of both. It *does* need testing.
5247 Some of the changes are general, *not* mips-specific.
5250 Didn't believe in little-endian bit order.
5251 There are still inconsistencies about whether flags
5252 like BITS_BIG_ENDIAN are integer (#if ...) or
5253 boolean (#ifdef ...). I tried to paper over them.
5255 dbxread.c,coffread.c,mipsread.c,symtab.c,symtab.h:
5256 Moved some misc_function code that was common to
5257 {dbx,coff,mips}read.c to symtab.c.
5258 In the process, I think I cleaned things up a bit.
5259 At the same time, moved obsavestring and obconcat to symtab.c.
5262 Removed obsolete condense_addl_misc_bunches (use
5263 condense_misc_bunches(1) instead).
5266 Needed to include <sys/dir>, at least on DECstations.
5268 valops.c, mips-tdep.c, tm-mips.h:
5269 Added PUSH_ARGUMENTS macro to support funny argument-pushing
5270 conventions (when STACK_ALIGN is insufficient).
5271 Needed on mips, where doubles need 8-byte alignment,
5272 but ints only need 4.
5275 Removed cruft that was not being used.
5276 Merged in many fixes (most from Frank Yellin, fy@lucid.com).
5279 Print $ before register-names (I think that makes things a little
5281 Never print two instructions, even if one delays.
5282 Removed hex-disassemble set_cmd. (This is not mips-specific,
5283 so I think the argument is whether it is generally worthwhile or not.
5284 I'm inclined to think not, given how easy it is to
5285 convert between radixes in gdb.)
5288 This is basically Alessando's code.
5289 It doesn't use obstacks; I changed it to use obstacks
5290 in a few minor places where using malloc causes a
5291 memory leak. (Probably, more places could/should be changed.)
5292 I added record_misc_function where it was missing.
5293 In symbol_file_command and add_file_command, I tried
5294 to make the code consistent with more recent versions.
5295 Minor sylistic changes in parse_procedure.
5296 Make a .gdbinfo. psuedo-symbol point back to the real
5297 procedure symbol (using the isym field).
5300 This is basically from my port, but with a lot of details
5301 and a number of routines merged in from Alessando's version.
5302 I basically used my code "raw" backtrace (use heuristics
5303 from the actual code, rather than symbol table info) - though
5304 the idea is Alessandro's. I feel my code is a little cleaner
5305 here, particularly in being a little more flexible, such as being
5306 able to handle gcc-produced code (which it now can).
5307 It also doesn't do frame caching (which is not useful
5308 more recent gdb versions).
5309 I also used my code for push_/pop_dummy, more or less.
5310 I tried to incorporate AF's code for testing sigtramp
5311 while backtracing; I probably got it wrong.
5312 Added mips_print_register, which tries to scrunch as much
5313 information as possible on a screen...
5314 Removed the skip-prologue set_cmd. As with hex-disassemble (see
5315 under mips-pinsn.c), I don't see anything mips-specific here,
5316 and I don't see it being all that useful anyway.
5319 Added a $fp psuedo-reg distinct from $fp (nice for gcc).
5320 Use more register names (rather than hard-cases numbers).
5322 Thu Sep 6 18:33:15 1990 John Gilmore (gnu at cygint)
5324 * Hack up 3.90.11 changes:
5326 * Makefile.dist (depend): parameterize $(GCC).
5327 Add solib.c and solib.o.
5328 (readline): Fix vpath for both absolute or relative SRCDIR.
5330 * blockframe.c: Fix from Schaefer@asc.slb.com for shared libs.
5331 Also, let the part I didn't understand at least compile so
5332 I can test the rest. FIXME.
5334 * dbxread.c: Fix thinko using strcmp.
5335 (init_psymbol_list): declare static.
5336 (partial_symbol_file_open): Comment cleanups better, avoid
5337 cleaning up the string table since the caller will do that.
5338 Move the stat for mod time into symbol_file_command, temporarily.
5339 (There should be a mod time for each symbol file, eventually,
5340 to control its rereading. FIXME.)
5342 * infptrace.c (PT_WRITE_D): use same value as PT_WRITE_I for
5343 SunOS, which gives error for shared libs otherwise. (From
5344 Schaefer, probably FIXME needs work for portability.)
5346 * solib.c: Move #include "param.h" to work.
5347 Lowercase all the Uppercase Letters In the Messages.
5348 (find_solib): Clean up inferior_so_name for debug printouts.
5349 Allow no argument, to mean all shared libraries.
5351 * symmisc.c: include param.h to get CLEAR_SOLIB.
5353 Wed Sep 5 18:00:08 1990 John Gilmore (gnu at cygint)

5397 (condense_misc_bunches): do "misc_function_count = j" regardless
5399 Take code which is shared between symbol_file_command and
5400 add_file_command and put it into partial_symbol_file_{open,read}.
5401 Split add_file_command into add_file_command and add_file.
5402 Make psymtab_to_symtab read in the string table if the file
5404 Two new parameters to read_dbx_symtab and start_psymtab.
5405 tm-sunos.h: New file.
5407 Tue May 22 17:43:03 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)

5424 * sparc-opcode.h: Add a bunch of new opcodes which Sun as supports.
5426 Thu May 17 15:04:09 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5428 * {t,x}m-sun386.h, sun386-xdep.c, {x,t}config/sun386

5443 Sat May 5 12:39:18 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5445 * Makefile.dist: Move -I${srcdir} to GLOBAL_CFLAGS and pass
5447 config.gdb: If srcdir != ., create readline directory and
5448 copy a makefile into it.
5450 * wait.h, infrun.c: Change WRETCODE to WEXITSTATUS for
5451 consistency with POSIX.
5453 * breakpoint.c (bpstat_stop_status): Disable watchpoint
5454 when we exit its exp_valid_block.
5456 Tue Sep 4 11:46:46 1990 John Gilmore (gnu at cygint)
5458 * Makefile.dist: Bump version to 3.91.3.
5460 * Clean up handling of breakpoint commands (somewhat).
5461 Prompted by Tiemann bug report "cont 10" doesn't work any more.
5463 inferior.h: Add breakpoint_proceeded to inferior status struct
5464 and globals; save it and restore it.
5465 (clear_breakpoint_commands): Cleanup, remove old #define.
5467 infrun.c (clear_proceed_status): Set breakpoint_proceeded.
5468 (save_inferior_status, restore_inferior_status): handle it also.
5469 (proceed): Remove earlier code that set breakpoint_proceeded.
5470 It is now set only in clear_proceed_status.
5471 (clear_proceed_status): Cleanup, use bpstat_clear rather
5472 than clear_breakpoint_commands. No callers need the stop_bpstat
5473 between clear_proceed_status and proceed.
5475 infcmd.c: Add breakpoint_proceeded definition and comment.
5476 (cont_command, jump_command, signal_command): Move call to
5477 clear_proceed_status right next to call to proceed.
5479 breakpoint.c (bpstat_do_actions): Avoid clobbering our
5480 caller's argument while running down the chain of breakpoints.
5481 Use new variable "breakpoint_proceeded" to determine when
5482 a command that it executes moves the inferior past the
5484 (bpstat_clear): Handle NULL argument.
5485 (bpstat_clear_actions): Avoid useless call to
5486 breakpoint_auto_delete.
5487 (delete_breakpoint): Clean up bpstat's that are pointing to
5488 the deleted breakpoint from the stop_bpstat chain.
5489 (breakpoint_auto_delete): Simplify.
5491 * Clean up handling of EOF, error on stdin, etc. This was
5492 prompted by a network problem that caused gdb to go into an
5493 infinite loop filling up its malloc'd memory.
5495 main.c (return_to_top_level): Cleanup: call bpstat_clear_actions,
5496 not clear_breakpoints_commands, which is now gone.
5497 (main): If command_loop returns (e.g. from EOF on stdin), do
5498 a quit_command (looping back to command_loop if quit_command
5499 doesn't really quit).
5500 (command_loop): check result from command_line_input and
5501 exit if it returns NULL, rather than passing the NULL to
5503 (gdb_readline): Free malloc'd result space before returning
5506 * utils.c (query): Handle C-d to mean "yes", just as if the
5507 input was not a terminal. Also avoid infinite loop if EOF
5508 occurs in mid-input-line before newline. This allows
5509 query to be used at EOF on stdin with reasonable results.
5511 * infrun.c (proceed): Set breakpoint_proceeded.
5513 * values.c (value_as_long): Avoid infinite recursion for enums.
5514 (_initialize_values): Fix typo in help msg (kingdon).
5516 * Makefile.dist (RL_LIB): Use RL_LIB_DEP for dependencies,
5517 RL_LIB for linking. This allows -lreadline for linking
5518 and nothing for dependencies, once readline is a real library.
5520 * config.gdb: Jim Kingdon: give useful error message if the
5521 host or target type is not recognized.
5523 * defs.h (alloca): SPARC <alloca.h> does not declare alloca,
5524 it just defines it. Dumb, but deal with it.
5526 * Jim Kingdon suggests:
5527 in xconfig/sun3os4, CFLAGS should be XM_CFLAGS.
5529 Wed Aug 29 18:03:27 1990 John Gilmore (gnu at cygint)
5531 * Makefile.dist (VERSION): Bump version # to 3.91.2.
5533 * Clean up Bothner's changes.
5535 * blockframe.c (clear_pc_function_cache): New function.
5536 * blockframe.c: remake cache_pc_function_* static.
5537 * dbxread.c (symbol_file_command): remove references to
5538 cache_pc_function_* variables.
5539 * dbxread.c (read_struct_type): Use VOFFSET_STATIC.
5540 * printcmd.c: Avoid kludging a global variable (addressprint)
5541 to avoid printing the address of a string twice. Instead,
5542 pass the format letter 's' down low enough that it can be seen
5543 to avoid this problem.
5544 (print_formatted): Pass format arg to value_print.
5545 (restore_addressprint): Remove function.
5546 (do_examine): Avoid hacking addressprint, cleanups and such.
5547 (print_frame_args): Add a comment to a Bothner change.
5548 * symtab.h: define VOFFSET_STATIC and use it instead of "-1".
5549 * symmisc.c (free_all_symtabs): Call clear_pc_function_cache
5550 to wipe out the values cached in blockframe.c.
5551 * symtab.c (find_method): Add comment saying how big you must
5552 allocate to be "big enough". Per being terse again.
5553 * valprint.c (val_print): Handle format letter "s" to print
5554 strings without addresses. Add comment to vtbl printing code
5555 which casts with wild abandon. Rearrange reference-printing
5557 @0xaddr: value (print w/addressprint)
5558 value (print w/~addressprint)
5559 @0xaddr (parameter lists w/addressprint)
5560 or nothing (parameter lists w/o addressprint)
5562 Tue Aug 28 10:47:18 1990 John Gilmore (gnu at cygint)
5564 * Merge more changes from Per Bothner:
5566 Gdb's handling of TYPE_CODE_REF was so counter-C++ (and otherwise
5567 annoying) that I tried to improve it. Here are my suggestions.
5569 These patches all attempt to handle TYPE_CODE_REF (as in C++) better.
5572 Do automatic de-reference when taking the address of a reference.
5574 Don't deref_ref when printing parameter lists.
5576 More attempts at treating refernences properly.
5578 In val_print, if deref_ref==0, don't print dangling " = ".
5580 Add COERCE_REF macro, which de-references an REF.
5582 * Merge changes from Per Bothner:
5584 * Fixed (Sony news)-specific configuration problems.
5585 * Fixed other problems with using vanilla pcc and libc (enum problems;
5586 assumption that vsprintf exists).
5587 * Some major speed-ups (finc_pc_partial_function now caches a match;
5588 parsing avoids duplicate symbol_lookup calls).
5589 * Changed handling of baseclasses (no longer use baseclasses field
5590 of struct type, use the first n_baseclasses fields instead).
5591 * Various minor changes/fixes, most C++-related.
5594 Cache the most previous match from find_pc_partial_function.
5595 (Save both low and high ends of matching function's pc range.)
5596 This speeds up the loop of infrun.c:wait_for_inferior quite
5597 a bit, and makes step/next commands much zippier.
5599 Added an enum->int cast (otherwise, some compilers barf).
5601 No longer set baseclass offset to 0, since multiple
5602 inheritance now mostly works.
5603 Added a number of casts, to shut up compiler warnings
5604 (after stabs where made enums, not ints).
5605 When discarding a symbol table (in symbol_file_command),
5606 must clear the cache introduced in blockframe.c.
5607 Don't convert $vtbl_ptr_type to vtbl any more.
5608 Get rid of TYPE_BASECLASEES and baseclass_vec (see also symtab.h).
5609 Mask off sign bit emitted by g++ for virtual table offset.
5610 Set voffset to -1 (not 1) for static member functions.
5612 Changed parsing/lexing of names to avoid doing symbol lookup twice
5613 (once when lexing to determine symbol class, once for real).
5614 Now only call symbol_lookup once. Fields of 'this' win especially big.
5616 Subpress printing addr twice in the case of 'x/s addr'.
5618 lookup_basetype_type is no longer used.
5619 Add find_methods as recursive helper function to decode_line_1.
5620 This allows multiple inheritance to work.
5621 Also, once one or more matches has been found, do not look in
5622 base-classes. (Baseclass methods would be overridden, anyway.)
5624 Removed baseclasses array in struct type.
5625 Instead of using baseclasses[i], use fields[i-1].
5626 Added virtual_field_bits[i] to indicate if the i'th baseclass is virtual.
5627 Changed sign convention of voffset (previous was inconsistent).
5629 Some macros (CALL_DUMMY and relatives) were missing. Put them back.
5631 Used to assume existence of vsprintf. Re-written to not need it
5632 if HAVE_VPRINTF is undefined.
5634 typecmp was too pessimistic. Made it less so.
5636 Don't print space after address.
5637 If vtable points to a misc symbol (with 0 offset), print it,
5638 since that indicates the actual class of the object.
5639 Changed ype_print_derivation_info to use new inheritance
5640 scheme (without baseclasses vector).
5642 In value_primitive_field, fixed some bugs left over from previous set of fixes.
5643 Also, changes needed because TYPE_BASECLASSES were removed.
5645 REGISTER_U_ADDR didn't work for PC. Rewrote to use an array.
5647 Tue Aug 21 20:08:54 1990 John Gilmore (gnu at cygint)
5650 If there is no path set, and the symbols don't indicate what directory
5651 a file was compiled in, look in the current directory. But either
5652 a path or a known compilation directory will prevent this.
5655 Three independent bug fixes:
5656 * Remove the #if 0 block that breaks some stuff.
5657 * SunOS 4.1 fixed the promoted-parameter-wrong-addr bug in Sun C;
5658 adapt gdb to either SunOS 4.0.* or 4.1.
5659 * MAX_OF_TYPE and MIN_OF_TYPE thinko. By tedg@sun, I think.
5662 Instantiate the class T when looking for methods in it. (Tiemann@sun)
5665 (type_print) Demangle the name being printed.
5666 (type_print_base) Handle botched demangling without coredump (tiemann).
5669 (check_stub_method): Document routine.
5670 (tiemann) fix bug for no-arg functions
5671 Avoid clobbering beyond end of malloc'd storage.
5672 Terminate the argument list properly.
5674 Sat Aug 18 01:29:59 1990 Per Bothner (bothner@cs.wisc.edu)
5676 * Changes merged by John Gilmore:
5679 In breakpoint_1, use new print_address_symbolic instead
5680 of find_pc_partial_function. (This forces use of assembler-level
5681 addresses, and avoids misleading non-mangled source-level names.)
5683 Generalize ansi argument such that -1 means skip arglist totally.
5684 Removed global variable print_ansi_qualifiers (which made
5685 code non-reentrant), in favor of extra explicit arguments
5686 to internal routines.
5688 Add new helper function print_address_symbolic.
5689 Use find_pc_misc_function instead of find_pc_partial_function
5690 (since we want assembler-level symbols here).
5692 Print unknown function as just "f (...)", not "f (...) (...)".
5693 Use new fputs_demangled explicitly.
5695 Fixed a typing violation (problem: value.h cannot be imported
5696 without renaming many variable in this file).
5697 lookup_symbol: If no matching misc_func, look for a C++-mangled name.
5698 decode_line_1: Moved forward some never-reached code.
5699 Made decode_line_2 skip function prologues correctly.
5701 fputs_filtered should not demangle by default.
5702 Add new fputs_demangled to demangle on demand..
5704 Change value_struct_elt to use value_primitive_field (using recursive
5705 utility function search_struct_field). This allows foo.bar to work
5706 for multiple inheritance (so far only for data fields).
5707 Change check_field in the same way (recursive helper function
5708 to support multiple inheritance).
5709 (Note: there are more of these problems that I haven't fixed.
5710 Any code that says TYPE_BASECLASS (t, 1) is probably wrong.)
5711 value_of_this: 'this' symbol name is now just "this", note "$this".
5713 Don't print static members.
5714 Avoid printing "members of <type>" if there are none.
5715 Simplified type_print_derivation_info by merging duplicate code.
5716 Remove useless blank lines in type_print_base (ptype command).
5718 Added declaration of new routine value_primitive_field.
5720 Added value_primitive_field which is generalized version of
5721 value_field that can handle multiple inheritance (non-zero offsets etc).
5722 Re-implemented value_field to call value_primitive_field.
5724 Fri Aug 17 23:33:44 1990 John Gilmore (gnu at cygint)
5726 * infcmd.c -- insert else to avoid 'delete env' coredump when you
5727 delete the whole environment. Karl Berry reported the bug.
5728 * source.c - fix openp to avoid //'s in filenames, which
5729 trigger an Emacs bug causing it to not be able to find files
5730 when running gdb in a window.
5731 * dbxread.c - zap the #if 0 that botches the add-file code.
5732 It seems to work a lot better without all the code commented out.
5734 Fri Jul 20 16:58:46 1990 John Gilmore (gnu at cygnus.com)
5736 * Merge Tiemann's and Ted Goldstein's changes, detailed below,
5739 Tue Jul 17 19:34:33 1990 Ted Goldstein (tedg at golem)
5741 * Makefile - added a ${CFLAGS} to a couple of entries,
5742 added remote-sa.sparc.c
5743 * added remote.sa-sparc.c, a modification of remote.c
5744 which conducts a dialog directly with the SparcStation prom.
5745 * breakpoint.c, infrun.c, sparcdep.c added
5746 remote_insert_breakpoint(), and remote_remove_breakpoint()
5747 to breakpoint.c instead of directly writing breakpoint instructions.
5748 * sparcdep.c on remote_debugging,there is no need
5749 to remove signle step breakpoint instructions.
5750 * main.c added "-epoch" flag and "int epoch_interface" to main.c
5752 * printcmd.c - epoch interface sends lisp expressions to open up
5753 epoch windows on inspection.
5754 * valprint.c - added arrayprint, and addressprint and made adding
5755 format controls easier
5756 * wait.h added a couple of undef's because we were getting
5757 complaints about WSTOPSIG and WTERMSIG begin redefined.
5760 Wed Jul 4 05:27:51 1990 Michael Tiemann (tiemann at masham)
5762 * symtab.c (decode_line_1): Add support for handling method stubs
5763 in the type information.

5767 * values.c (baseclass_addr): Run loop from INDEX+1 to
5768 N_BASECLASSES; otherwise, we can still get into a loop.
5769 @@ This should be restructured to use a cleaner search strategy.
5771 Sun Jul 1 12:28:51 1990 Michael Tiemann (tiemann at masham)
5773 * dbxread.c (define_symbol,read_type): Grok GNU C++'s new
5774 abbreviation "Tt" for tags which have the same name as their
5777 Fri Jun 29 01:03:46 1990 Michael Tiemann (tiemann at masham)
5779 * symtab.c (list_symbols): add ability to set breakpoints on all
5780 the functions which match a particular regular expression.
5782 Tue Jun 26 04:26:29 1990 Michael Tiemann (tiemann at masham)
5784 * cplus-dem.c (cplus_demangle): New parameter ANSI says whether we
5785 should print ANSI qualifiers (such as `const' and `volatile').
5786 All callers changed to call with ANSI == 1, except from
5787 `check_method_stub', which uses old-style syntax.
5789 * symseg.h (struct fn_field): Remove unneccessary `args' field.
5790 * symtab.h (TYPE_FN_FIELD_ARGS): Redefined.
5792 * values.c (check_stub_method): New function.
5794 * cplus-dem.c (do_type): Handle "long long" (encoded as 'x').
5796 * dbxread.c (read_type): Handle new GNU C++ method type stubs.
5797 * valprint (type_print_base): Ditto.
5799 * symtab.c (gdb_mangle_typename): New function.
5801 Tue Jun 5 00:18:43 1990 Michael Tiemann (tiemann at gzilla)
5803 * breakpoint.c (catch_command): New function. Provides a
5804 mechanism to set breakpoints based on catch clauses.
5805 (disable_catch): Similar, but disables breakpoints on catch
5807 (delete_catch): Similar, but deleted breakpoints on catch clauses.
5809 Sun Jun 3 22:54:08 1990 Michael Tiemann (tiemann at gzilla)
5811 * blockframe.c (blockvector_for_pc): New function.
5812 * blockframe.c (block_for_pc): Changed to call
5813 `blockvector_for_pc' and get the block itself.
5815 * stack.c (catch_info): New function. Prints info about
5816 exceptions which can be caught in the current frame.
5817 * stack.c (print_frame_label_vars): New function. Similar to
5818 `print_frame_local_vars'.
5819 * stack.c (print_block_frame_labels): Prints out labels that are
5820 defined in this frame. These labels are exceptions that can be
5823 * dbxread.c: Updated to handle N_CATCH symtab types.
5825 Thu May 3 22:10:00 1990 Michael Tiemann (tiemann at teacake)
5827 * valprint.c (everywhere): TYPE_NAME (TYPE) no longer comes in the
5828 form "struct ..." for GNU C++. Don't flush any part of TYPE_NAME
5829 when printing the type.
5831 Wed May 2 22:43:04 1990 Michael Tiemann (tiemann at teacake)
5833 * valprint.c (val_print): Use `baseclass_addr' to access the
5834 baseclasses pointed to via the derived class object at VALADDR.
5836 * values.c (baseclass_addr): New function. Casts derived pointers
5837 to baseclass pointers taking virtual baseclasses and multiple
5838 inheritance into account.
5840 Sat May 5 12:39:18 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5844 Fri May 4 12:12:55 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5846 * breakpoint.c (watch_command, bpstat_stop_status): Deal with
5847 exp_valid_block field correctly.
5849 * infrun.c (wait_for_inferior): When checking "don't even think
5850 about breakpoints" if stop_signal == SIGTRAP && trap_expected,
5851 also check step_resume_breakpoint.
5852 Insert breakpoints and continue (not step) if
5853 step_resume_break_address != NULL, even if another_trap.
5854 If trap_expected and we enter sigtramp, then set up a
5856 If trap_expected is set when we hit the step_resume_break,
5858 When calling resume and trap_expected says tell resume to step
5859 (2 places), also check step_resume_break_address.
5861 * infrun.c (wait_for_inferior): Don't set
5862 prev_{pc,sp,func_{start,name}} before calling wait ().
5863 Do set them after exiting loop.

5865 (start_inferior): Initialize them.
5867 Thu May 3 00:15:11 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5869 * infrun.c (wait_for_inferior, after check for trap_expected > 1):
5870 Restore old code which distinguishes between trap_expected and
5871 running_in_shell, just make the latter take any non-TRAP signal,
5874 * values.c (allocate_value): Zero VALUE_OPTIMIZED_OUT flag.
5876 * Makefile.dist (pinsn.o): Use PINSN_CC to compile.

5898 * valprint.c (value_print): Check VALUE_OPTIMIZED_OUT flag.
5900 * value.h: Add optimized_out field and change lazy field to
5901 char. Add macro VALUE_OPTIMIZED_OUT.
5903 * i386-pinsn.c: Change from Eirik Fuller to write to stream directly
5904 instead of stuffing things in buffers (oappend, etc).
5906 * breakpoint.c (bpstat_do_actions): If *BSP is set to NULL by
5907 execute_command, exit both loops.
5909 * Makefile.dist: Don't set TARGET_ARCH. Add .c.o rule.

5914 rgdb.c, rserial.c, rudp.c, serial.c, udp.c, xdep.h,
5916 m68k-xdep.c, coredep.c: Wrap in #if !defined (RDB).
5918 * valops.c (value_struct_elt), values.c (value_static_field):
5919 Change error messages to remove references to `info methods'.

5924 infrun.c (start_inferior): Add START_INFERIOR_HOOK.
5925 infcmd.c [SHIFT_INST_REGS]: New code.

5933 Mon Apr 23 10:42:21 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5936 findvar.c (get_saved_register): New function.
5937 findvar.c: Rewrite code which called find_saved_register to
5938 call get_saved_register instead.
5940 Sun Apr 22 14:47:51 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5942 * valprint.c (val_print): Change error message printed when
5943 the type has TYPE_FLAG_STUB set.

5956 (store_inferior_registers): Don't call read_register_bytes.
5957 symmetry-xdep.c (store_inferior_registers):
5958 #if 0 out code to fetch registers.
