1 Fri Nov 22 08:27:40 1991 John Gilmore (gnu at cygnus.com)
3 * Roll VERSION to 4.2.95.
5 * buildsym.c, coredep.c, mem-break.c, xcoffread.c: Put <stdio.h>
7 * config/mh-i386sco: Override compiler to gcc, print warning.
8 * configure.in: Handle i386-none-aout rather than i386-aout-none.
9 * infptrace.c, language.h, utils.c: Lint.
10 * m2-exp.y: #undef MAX and MIN in case system includes set them.
11 * xm-tahoe.h: Set HOST_BYTE_ORDER. Include system versions of
12 {BIG,LITTLE}_ENDIAN and the INT_MAX family first, to avoid
13 redefinition warnings.
14 * defs.h: Reorder things so that the xm-file gets first crack
15 at #define's, followed by defs.h and then the tm-file.
16 * Makefile.in: Remove spaces after 'ignore exit code' - flags.
17 Late-model BSD 'make's don't cope with them.
19 Thu Nov 21 23:48:56 1991 John Gilmore (gnu at cygnus.com)
21 * Makefile.in: Roll new files into various lists.
23 Thu Nov 21 18:26:11 1991 Fred Fish (fnf at cygnus.com)
25 * dwarfread.c (struct_type): Must initialize the c++ specific
26 portion of union types as well as struct types, since gdb attempts
27 to reference the c++ specific info for both types.
29 Thu Nov 21 10:23:52 1991 John Gilmore (gnu at cygnus.com)
31 * Makefile.in: Roll VERSION to 4.2.90.
33 * defs.h: Incorporate param.h into defs.h. All users changed.
34 * param-no-tm.h: Change users to define TM_FILE_OVERRIDE instead.
35 * param.h, param-no-tm.h: Removed.
36 * Update copyrights in all changed files.
37 * dbxread.c, dwarfread.c, inflow.c, infrun.c, m2-exp.y, putenv.c,
38 solib.c, symtab.h, tm-umax.h, valprint.c: Lint.
39 * tm-convex.h, tm-hp300hpux.h, tm-merlin.h, tm-sparc.h,
40 xm-merlin.h: Avoid host include files in target descriptions.
41 * getpagesize.h: Removed, libiberty copes now.
42 * Makefile.in: Remove getpagesize.h, param.h, param-no-tm.h.
44 * exec.c (exec_files_info): If `verbose' is set, show file offset

48 * standalone.c: Fake getcwd rather than getwd.
49 * xm-*.h: Remove fake values of MAXPATHLEN.
51 * xcoffexec.c: Add /* */ to #if 0'd thing to help ANSI.
53 Wed Nov 20 18:35:56 1991 John Gilmore (gnu at cygnus.com)
55 * Remove gdb/hp-include. Support for HP a.out oddities should be
56 in BFD, not in GDB. Move gdb/hp-include/a.out.h to include/a.out.hp.h.
58 * infptrace.c, tm-sun386.h: Cashier <a.out.gnu.h>, remove refs.
60 * configure.in, xconfig, tconfig, Makefile.in, doc/gdbint.texinfo:
61 Makefile fragments for various hosts and targets now come from
62 gdb/config/mh-* and gdb/config/mt-*. This is for consistency with
65 * rs6000-pinsn.c, rs6k-opcode.h: Clean up.
66 * rs6k-opcode.def: Delete.
68 Wed Nov 20 05:04:40 1991 Fred Fish (fnf at cygnus.com)
70 * dwarfread.c: Recognize obsolete form of AT_element_list
71 attribute still used by at least one AT&T compiler, and possibly
74 Tue Nov 19 07:53:55 1991 Fred Fish (fnf at cygnus.com)
76 * dwarfread.c (enum_type, struct_type): Ignore names invented by
77 helpful compilers for anonymous structs, unions, and enums.
79 * c-exp.y, m2-exp.y: Add defines for yymaxdepth, yy_yys, and
80 yy_yyv, so multiple parsers produced by SVR4 versions of yacc
81 can coexist in the same executable without collision.
83 * symtab.h: Add declaration for lookup_template_type() to kill
84 compiler warnings about conversions from int to pointer.
86 Mon Nov 18 17:45:18 1991 Fred Fish (fnf at cygnus.com)
88 * procfs.c: Move inclusion of defs.h to before param.h, as in
89 all the other source files that include both. This is required
90 to supply some typedefs that are used in files included by param.h.
92 * m68k-tdep.c (m68k_skip_prologue): Add generic m68k support for
93 skipping function prologues, ala the other cpu families (i386,
94 mips, m88k, etc). Add the ability to skip movm and fmovm
95 instructions in the prologues. Still needs support for profile
96 (-p compiled) prologue sequences (FIXME).
98 * tm-68k.h: Change SKIP_PROLOGUE macro to use the new generic
99 m68k prologue skipping function by default.
101 * tm-altos.h, tm-isi.h: Continue to use the old definition of
104 Mon Nov 18 15:12:45 1991 John Gilmore (gnu at cygnus.com)
106 * Makefile.in: Remove tdesc stuff, and extra blanks before colons.
107 * blockframe.c: Remove tdesc-related code. Default
109 * infrun.c: Remove tdesc-related code.
110 * m88k-tdep.c (frame_chain_combine, init_frame_pc): Remove copies
111 of defaultable things.
112 * tm-m88k.h: New file, common to all Moto 88k target configs.
113 Derived from tm-delta88.h.
114 * tm-delta88.h: Use it.
115 * xm-m88k.h: Common file for 88K hosts. Remove obsolete stuff.
116 * xm-delta88.h: Use it.
117 * tm-*.h: Remove FRAME_CHAIN_COMBINE macros, since all are
119 * coffread.c: Remove tdesc stuff.
120 * tconfig/delta88, tconfig/m88k: Remove tdesc stuff.
121 * xconfig/m88k: Rename tm-88k.h to tm-m88k.h.
123 Mon Nov 18 13:51:37 1991 Per Bothner (bothner at cygnus.com)
125 * source.c (open_source_file): If openp fails, try again
126 using just the base (non-directory) part of the filename.
127 This solves various annoying problems, such as when the
128 source was compiled with an absolute pathname - and the
129 source files have moved. Or if the source was compiled
130 using a relative pathname, it can be more convenient
131 to just specific the source directory to the dir command.
133 Mon Nov 18 00:04:41 1991 Fred Fish (fnf at cygnus.com)
135 * cplus-dem.c (munge_function_name): Add missing third arg to
136 instance of call to do_type().
138 * dwarfread.c: Changes to match new dwarf.h. Remove
139 AT_deriv_list, AT_loclist, AT_incomplete, AT_const_data,
142 Sun Nov 17 16:20:53 1991 Michael Tiemann (tiemann at rtl.cygnus.com)
144 * symtab.h (struct type): Moved C++-specific fields into new type
145 `struct cplus_struct_type'. Now takes 10% less memory. Many
147 * symtab.c (init_type): Don't set fields belonging to
148 TYPE_CPLUS_SPECIFIC unless TYPE is TYPE_CODE_STRUCT.
149 * buildsym.c (read_type): Allocate TYPE_CPLUS_SPECIFIC for
151 (read_struct_type): Ditto. Also, add comments about how we can
152 deduce TYPE_VPTR_FIELDNO from inheritance info and fieldname info.
153 * coffread.c (decode_base_type): Allocate TYPE_CPLUS_SPECIFIC for
155 (read_struct_type): Ditto.
156 * dwarfread.c (struct_type): Ditto.
158 * symtab.c (read_range_type): Don't set TYPE_MAIN_VARIANT.
159 (lookup_pointer_type): Don't use or set TYPE_MAIN_VARIANT.
160 (lookup_reference_type): Ditto.

169 * mipsread.c (parse_partial_symbols): patch to keep DEC C
170 compiler from making gdb bomb out. Thanks to Ed Santiago!
172 Thu Nov 14 19:27:30 1991 Fred Fish (fnf at cygnus.com)
174 * symfile.c: Add function compact_misc_function_vector() to
175 remove duplicate misc function vector entries. See comments
176 in source for why this is necessary/desirable.
178 * dwarfread.c: Add misc function type parameter to internal
179 record_misc_function(). Remove calls to init_misc_bunches()
180 and condense_misc_bunches(), these are now done in elfread.c.
182 * elfread.c: Add support for reading bfd canonical symbol tables
183 and generating misc function vector entries for global and
184 absolute symbols. Do calls to init_misc_bunches() and
185 condense_misc_bunches() where they will enclose all calls to
186 record_misc_function(), including those in dwarfread.c.
188 Thu Nov 14 17:02:11 1991 Roland H. Pesch (pesch at cygnus.com)
190 * doc/Makefile.in: new targets gdb.me, gdb.ms, gdb.mm
191 (roffable documentation).
192 * doc/gdb.texinfo: embedded hints (as comments) for better
193 texi2roff conversion.
195 Thu Nov 14 13:18:25 1991 John Gilmore (gnu at cygnus.com)

209 Motorola 88000 port without tears, I mean without tdescs.
211 * m88k-tdep.c: Blow away all tdesc stuff.
212 Provide functions for all the frame-related macros in
213 tm-delta88.h. Adopt i960-style EXTRA_FRAME_INFO.
214 (examine_prologue, frame_find_saved_regs, skip_prologue): borrow
215 from i960-tdep.c and adapt to the function prologues on the 88k.
216 (read_next_frame_reg): Borrow from mips-tdep.c.
217 FIXME: frame_locals_address should go away.
219 * tm-delta88.h: Dump all the tdesc stuff.
220 Macros for all frame-related stuff call fns of same name.
221 Remove duplicated definitions. FP_REGNUM becomes same as
224 * xm-88k.h: Eliminate lots of library dependencies, now handled
225 in libiberty. Eliminate KDB nonsupport.
227 * doc/gdbint.texinfo: Add rudiments on frames. FIXME, add more.
230 * stack.c (frame_info): Mark frameless functions.

248 Allow setting breakpoints on C++ destructors.
249 * valops.c (destructor_name_p): Don't check TYPE_HAS_DESTRUCTOR,
250 since it lies. Rely on callers to catch missing destructors.
251 * symtab.c (decode_line_1): For example (see above), here.
252 * buildsym.c, symtab.h: Remove TYPE_FLAGS_HAS{CON,DE}STRUCTOR
253 flags since they are no longer used.
255 Fixes to support C++ methods with functional parameters.
256 * c-exp.y (func_mod rule): Allow (and ignore) list of parameter
257 types in a function type.
258 * eval.c (parse_and_eval_type), value.h: New function,
259 parse_and_eval_type, is based on old code from check_stub_method.
260 But don't actually evaluate the cast, since that calls
261 value_cast(), whcih may fail. Just extract the type
262 from the parsed expression.
263 * values.c (check_stub_method): While looping through the
264 arguments, adjust depth *after* parameter has been handled.
265 Replace call and setup of parse_and_eval with new function
268 Tue Nov 12 09:40:07 1991 Fred Fish (fnf at cygnus.com)
270 * utils.c, rem-multi.shar: Remove fixed arg count version of

275 m88k-xdep.c, main.c, printcmd.c, pyr-xdep.c, source.c,
276 sun386-xdep.c, symm-xdep.c, umax-xdep.c, values.c, xcoffread.c:
277 Change all instances of use of fixed args concat() to variable
278 args concat() now located in libiberty.
280 Tue Nov 12 07:23:46 1991 John Gilmore (gnu at cygnus.com)

286 * rs6000-pinsn.c, rs6000-tdep.c, rs6000-xdep.c, tm-rs6000.h,
287 xm-rs6000.h, rs6k-opcode.def, rs6k-opcode.h: New files.
288 * xcoffexec.c: New file for handling AIX shared libraries.
290 Mon Nov 11 19:14:31 1991 Fred Fish (fnf at cygnus.com)

304 * dwarfread.c (dwarf_psymtab_to_symtab): Remove leftover call
305 to do_cleanups() which resulted from a previous change.
307 * elfread.c: Re-enable compilation of register_addr() stub
308 whenever it is not supplied by coredep.c
310 Sat Nov 9 00:40:32 1991 John Gilmore (gnu at cygnus.com)
312 Add tracking of object files (that contain symbols) to gdb.
313 This includes a "struct objfile" that owns symtabs and psymtabs
314 that were read in from that binary file.
316 * symfile.h: Add struct objfile. Add pointer to the objfile
317 into the struct sym_fns.
318 Replace global `symfile' and `symfile_mtime' with
319 `symfile_objfile'. Add global object_files chain.
321 * symfile.c: Move param.h above symtab.h.
322 (sort_misc_function_vector): Add.
323 (syms_from_objfile): Was syms_from_bfd.
324 (symfile_open): Now returns objfile.
325 (allocate_objfile): New.
326 (free_objfile): New, replacing free_all_.*symtabs.
327 (symfile_init): Takes objfile arg, puts it in sym_fns result.

348 (dbx_alloc_type): Check file number, not sym number, for -1.
349 (find_symbol_in_list): Add for xcoffread.
350 (start_symtab): Default typevector is empty. Keep reusing same
352 (end_symtab): Take objfile argument and pass it to

378 (struct symtab): Add objfile * and objfile_chain * of symtabs.
379 (struct partial_symtab): Add objfile * and objfile_chain * of
380 psymtabs. Remove symfile_name.
382 * symmisc.c: Lose free_all_symtabs, free_all_psymtabs.

384 listing if 2nd argument given. Print objfile info.
385 (printpsyms_command): Rename from print_partial_symtabs. Ditto all.

389 * symfile.h, symfile.c, symtab.h: Lint
391 Fri Nov 8 23:38:48 1991 John Gilmore (gnu at cygnus.com)
393 * command.c: Include param.h.

400 Thu Nov 7 18:26:15 1991 Steve Chamberlain (sac at rtl.cygnus.com)
402 * Makefile.in: link with libiberty after libreadline, since
403 readline might want something in libiberty.
404 * m88k-xdep.c: Fixed the register offsets in the ptrace_user
405 struct for BCS 88k machines.
406 * xm-m88k.h: don't define USIZE if already defined.
407 * configure.in: Added delta88 target.
409 Thu Nov 7 04:51:19 1991 John Gilmore (gnu at cygnus.com)
411 * am29k-pinsn.c, am29k-opcode.h: Fix decoding of mtacc, dmac, fmac.
413 * tm-*.h: Remove READ_DBX_FORMAT, COFF_FORMAT, and
414 READ_MIPS_FORMAT, which have been unused since BFD. Still
415 remaining is COFF_NO_LONG_FILE_NAMES.
416 * tm-sun3.h, tm-altos.h: Remove detritus accidentally left from
417 function calling code moved to m68k-tdep.c.
419 Wed Nov 6 17:21:59 1991 John Gilmore (gnu at cygnus.com)
421 * coffread.c: Eliminate c_nsyms in favor of c_naux.
422 Complain if no auxents on .bf and .ef FCN symbols, and assume
423 lots of line numbers.
424 (init_linenos, enter_linenos): Use a sentinel at the end of the
425 read-in linenos, to make for a fast, safe loop-end test.
427 Wed Nov 6 02:54:08 1991 Steve Chamberlain (sac at cygnus.com)
429 * coffread.c (read_coff_symtab): coffread used to rely on the
430 x_sym.x_misc.x_lnsz.x_lnno field giving the # of linnos in a
431 function. Two of the formats I'm using (29k and 88k) don't seem to
432 set it. Ths patch to fcn_last_line and (enter_linenos) is an
433 attempt to use the actual size of the linno table in the file to set
434 the number of linenos to process.
436 Tue Nov 5 22:47:46 1991 Steve Chamberlain (sac at cygnus.com)
438 * Makefile.in: put a - infront of the mv y.tab.c c-exp.tab.c and
439 mv y.tab.c m2-exp.tab.c, so that if bison is used, and the files
440 are created in place, so the mv fails, then the make continues.
442 Tue Nov 5 16:47:47 1991 Per Bothner (bothner at cygnus.com)
444 Add C++ as a separate language.
445 * defs.h (enum language): Add language_cplus.

447 * c-exp.y: Add new struct language_defn cplus_language_defn.
448 Don't set c to be the default language (see main.c).
449 * c-exp.y (yylex): Only look for field of this if
450 language is C++. (First difference from C!)
451 * language.c: Add case branches for C++ (currently, all
452 the same as C). Also, add c++ to "usage" note for "set lang".
453 * valprint.c (typedef_print). Add case branches for C++.
454 * main.c (main): New way to set initial language: Look at
455 file extension of psymtab containing main(). (Same as we
456 do for symtabs, but avoid loading the symtab yet.)
457 * symtab.c: New routine find_main_psymtab(), used by main()
458 to set initial language.
459 * symfile.c (allocate_symtab): Move code for mapping file
460 extensions-> languages to new deduce_language_from_filename().
462 Fix a C++ problem when looking for methods in super-classes.
463 There was confusion between base and derived types.
464 * valops.c (value_fn_field): Change function interface.
465 * values.c: Use new value_fn_field interface.
467 Mon Nov 4 10:49:33 1991 Per Bothner (bothner at cygnus.com)
469 * infrun.c: Fixed typo in comment.
470 * utils.c: All the v*fprintf emulation is now in libiberty,
471 so we can get rid of some junk.
472 * xm-sun3os4.h, xm-sun4os4.h, xconfig/decstation, xconfig/i386sco,
473 xconfig/sun3os4, xconfig/sun4os4: Don`t need HAVE_STRSTR any more.
474 * m68k-pinsn.c (print_insn_arg): Support BB/BW/BL
475 type operands, as used by branch instructions.
476 * gmalloc.c: Fix prototype of memcpy.
477 * elfread.c: Comment out register_addr, since it conflicts
478 with the one in coredep.c.
479 * buildsym.h: Remove extern declarations of two functions
480 that are really static in buildsym.c.
481 * tm-mips.h: Add symbolic names for more registers.
482 * mips-xdep.c (store_inferior_registers): Use new register names.
483 * xm-mips.h: Simplify REGISTER_U_ADDR, since it is now
484 only used for core files, not ptrace. Therefore,
485 the KERNEL_U_ADDR hack is no longer needed.
486 The mapping to ptrace number is now in in mips-xdep.c.
487 * mips-xdep.c: Define REGISTER_PTRACE_ADDR (using the
488 mapping from the old REGISTER_U_ADDR), and use it
489 in {fetch,store}_inferior_registers.
490 * mipsread.c: Rename #include ecoff.h to new name coff-mips.h.
491 * mips-tdep.c (mips_push_dummy_frame, mips_pop_frame):
492 Save/restore FP regs correctly (?).
493 * dbxread.c: Remove duplicate define_symbol and type_synonym_name
494 (these had been previously moved to buildsym.c).
495 Hence, define_symbol becomes extern instead of static.
496 * buildsym.c (read_struct_type): Comment out bogus handling
497 of C++ operator methods. Minor hacking of reading of class
498 contexts. Make define_symbol non-static, so dbxread.c can call it.
500 Fri Nov 1 11:05:47 1991 John Gilmore (gnu at cygnus.com)
502 * mipsread.c (read_mips_symtab, read_the_mips_symtab): Use real
503 filename with error messages.
504 * stack.c (frame_select_command): Rename to select_frame_command
505 to avoid "fr" and "fra" having nonunique completions.
506 * symfile.c (sort_symtab_syms): Ignore sort of zero symtab *.
507 (symfile_init): Print file format name when unable to handle it.
508 (free_named_symtabs): Use BLOCKVECTOR rather than obsolete BLOCKLIST.
509 * symmisc.c (free_symtab): Only free linetable if nonzero.
510 * symtab.h: Remove obsolete BLOCKLIST macros.
512 Thu Oct 31 18:12:43 1991 Stu Grossman (grossman at cygnus.com)
514 * infrun.c (wait_for_inferior): another stepi/nexti fix. Ensure
515 that stop_step is 1 at bottom of main loop. I don't know why this
516 needs to be done, but it helps me sleep better at night.
518 Sun Oct 27 18:18:39 1991 Stu Grossman (grossman at cygnus.com)
520 * main.c (initialize_history): Read history after reading all
523 Sun Oct 27 14:09:25 1991 John Gilmore (gnu at cygnus.com)
525 * buildsym.c: Break out initial malloc sizes.
526 (record_line): Record directly in a subfile. Alloc on demand.
527 (compare_line_numbers): Add from xcoffread.c.
528 (end_symtab): New params say whether to sort pendings and
529 linetable. Patch block stabs if defined. Shrink linetable before
530 allocating the symtab.
531 * buildsym.h: Delete line_vector* and prev_line_number. Add
532 global_stabs and file_stabs for xcoffread.
533 * dbxread.c (start_subfile): Move to buildsym. Change above calls.
534 * symtab.h: LINETABLE(symtab) can now be null. Zap LINELIST.
535 * symmisc.c, symtab.c: Cope with null LINETABLEs.
537 * blockframe.c: Pass fromleaf to INIT_EXTRA_FRAME_INFO.
538 * tm-29k.h, tm-88k.h, tm-i960.h, tm-irix3.h, tm-mips.h, tm-pyr.h,
539 tm-sparc.h: Accept fromleaf parameter.
540 * c-exp.y (yyerror): Pass error message if given.
541 * configure.in: Add rs6000 host and target.
542 * inflow.c (new_tty): O_NOCTTY kludge for RS/6000.
543 * symfile.h (entry_point): Add.
545 Sat Oct 26 00:16:32 1991 John Gilmore (gnu at cygus.com)
547 * buildsym.c: New file. Breaks out symbol-table-building routines
548 from dbxread.c, so they can be shared with xcoffread.c.
549 * buildsym.h: New file. Declarations for buildsym.c users.
550 * dbxread.c: Remove large chunks into buildsym.c.
551 * Makefile.in: Add buildsym.c and buildsym.h.
553 * symfile.c (syms_from_bfd): New routine.
554 (add_symbol_file): Call it to do the real work.
555 (syms_from_bfd): Initialize entry_point before calling symfile_init.
556 * symtab.h, symfile.c, coffread.c, mipsread.c, dwarfread.c:
557 Avoid declaring or setting entry_point (symfile.h & symfile.c cope).
559 Fri Oct 25 10:58:16 1991 Mark Eichin (eichin at cygnus.com)
561 * cplus-dem.c (cplus-demangle): added support for templates, static
562 data, and the new (correct) mangling for destructors.
564 * dwarfread.c: (dwarfwarn): created a varargs version of
565 dwarfwarn, for non __STDC__ compilers.
567 * c-exp.y: (yylex): added match for "template" token.
568 (typebase): added TEMPLATE name '<' type '>' clause, for explicit
569 specification of template types.
571 * symtab.c: (lookup_template_type): new function for finding
572 templates in symbol table.
573 (type_name_no_tag): changed to explicitly check for s/u/e at the
574 beginning of the symbol - if it is a template, none of these will
575 be there (but the name will still contain spaces.)
577 Fri Oct 25 18:59:32 1991 Per Bothner (bothner at cygnus.com)
579 Various fixes to improve g++ debugging.
580 * symtab.h: Add is_const and is_volatile flags for each method.
581 These are bit fields - take their space from voffset,
582 which shrinks to 30 bits. Since voffset is now a bitfield,
583 make it unsigned for portability. This changes its interpretation
584 slightly: Static methods now have voffset 1 instead of -1,
585 and virtual offsets start at 2, not 1.
586 * symtab.c: Renamed gdb_mangle_typename to gdb_mangle_name,
587 since it now returns an entire magled method name, not just
588 the type part. This avoids some duplication.
589 It also allows us to correctly mangle const and volatile
590 methods (using the new is_const and is_volatile bit fields
592 * valprint.c (type_print_base), values.c (check_stub_method):
593 Simplify by using new gdb_mangle_name.
594 * values.c (value_headof): Fix to correctly handle single
595 inheritance (actually two fixes, either of which suffices).
596 * dbxread.c (read_struct_type): Handle const and volatile
598 * dbxread.c (read_struct_type): Yet one more place where
599 we must handle '\\' continuations.
600 * valprint.c (vtbl_ptr_name): Add final '\0'.
602 Fri Oct 25 16:06:38 1991 Stu Grossman (grossman at cygnus.com)
604 * tm-sparc.h, tm-68k.h (EXTRACT_RETURN_VALUE): fix output of
605 short return values for sparc and 68k. Patch from Paul Eggert.
607 * coffread.c, coredep.c, i386-xdep.c: install patches for
608 SysV/386 3.2 from Mauro DePalma.
610 Fri Oct 25 02:02:13 1991 John Gilmore (gnu at cygnus.com)
612 * core.c (core_file_info), exec.c (exec_file_info): Print file
613 type. Use printf_filtered.
615 * valops.c (value_fetch_lazy): Avoid 0-length fetches.
617 Thu Oct 24 23:06:40 1991 Fred Fish (fnf at cygnus.com)
619 * dwarfread.c: Add casts to remove compiler warnings.
621 * tm-3b1.h, tm-68k.h, tm-altos.h, tm-amix.h, tm-hp300bsd.h,
622 tm-hp300hpux.h, tm-isi.h, tm-news.h, tm-pn.h, tm-sun2.h,
623 tm-sun3.h: Remove locally duplicated code for calling functions
624 in the inferior. The only differences were in the specific trap
625 vectors used and whether or not an fpu was present. These are
626 now handled by appropriate definitions of BPT_VECTOR and
627 HAVE_68881 respectively. Other minor obvious cleanups.
629 * valops.c: Correct a minor misspelling.
631 * utils.c: Remove local BSD/USG hacks that are now in libiberty.
633 * dwarfread.c: Remove prototype for dwarfwarn. Does not work
636 Thu Oct 24 09:33:44 1991 John Gilmore (gnu at cygnus.com)
638 * stack.c (frame_command): Always print. Use new
639 frame_select_command to select a frame without printing.
641 * dwarfread.c: Use <varargs.h>, since <stdarg.h> is not portable.
643 Thu Oct 24 01:32:51 1991 Fred Fish (fnf at cygnus.com)
645 * dwarfread.c: New file for DWARF debugging format support.
647 * elfread.c: New file for ELF object file format support.
649 * procfs.c: New file for SVR4 /proc (process file system) support.
651 * tm-amix.h, xm-amix.h, tconfig/amix, xconfig/amix: New files for
654 * xm-svr4.h, tm-svr4.h: New files for SVR4 support.
656 * xm-m68k.h: New file for host machines with m68k cpu.
658 * Makefile.in: Add elfread.c and dwarfread.c to SFILES_MAINDIR.
659 Add elfread.o and dwarfread.o to OBS.
661 * symfile.h: Add "elf" to list of supported formats in comment.
663 * c-exp.y, defs.h, symtab.h, valprint.c: Add three new builtin
664 types to gdb, builtin_type_long_double, builtin_type_complex, and
665 builtin_type_double_complex. Add and use new TARGET_SHORT_BIT,
666 TARGET_INT_BIT, TARGET_LONG_BIT, TARGET_FLOAT_BIT,
667 TARGET_DOUBLE_BIT, TARGET_LONG_DOUBLE_BIT, TARGET_COMPLEX_BIT, and
668 TARGET_DOUBLE_COMPLEX_BIT, as the sizes in bits of the indicated
669 types on the target machine (ala the existing TARGET_LONG_LONG_BIT).
671 * infrun.c: When using SVR4 /proc interface instead of ptrace(),
672 call proc_set_exec_trap() to setup child to stop at first instruction.
674 * inftarg.c: When using SVR4 /proc interface, call proc_wait()
677 * m68k-tdep.c: Add new routines supply_gregset(), fill_gregset(),
678 supply_fpregset(), and fill_fpregset(), which are machine
679 dependent support routines for SVR4 /proc interface.
681 * utils.c: Add warning_setup() and warning(). Warning() behaves
682 the same as error() except that it returns normally rather than
683 jumping back to command level. Modules that don't want to call
684 warning() for some reason, but want to produce their own warnings,
685 can call warning_setup() to ensure compatibility with the way
686 warning() and error() deal with the terminal.
688 * symtab.c: Make internal errors produce more useful messages.
690 * tm-68k.h: Move code that is duplicated in almost every single
691 m68k based machine's configuration files to this common file.
692 Duplications in the configuration files still need to be removed
695 * infrun.c (child_create_inferior): System V versions must call
696 setpgrp() with no arguments, to comply with prototyping typically
699 * munch: Add support for SVR4 style nm output.
701 * dbxread.c, mipsread.c symmisc.c, symtab.c: Remove the object
702 file specific fields from the partial symbol table structure and
703 replace them with a pointer to private data for each different
704 flavor of object file reader to initialize appropriately.
706 Wed Oct 23 09:38:20 1991 John Gilmore (gnu at cygnus.com)
708 * xconfig/sun[34]os4: Add note about strstr botch on sunos4.0.3c
711 * mipsread.c (fixup_undef_type): New function. If a struct /
712 union / enum is defined in a header file but nowhere else used,
713 (by typedefing, pointer referencing or declaration) the mipsread code
714 builds the complete tree for the structure but leaves its code as
715 TYPE_CODE_UNDEF as it doesn't know what kind of aggregate it is.
716 Guess its type based on the details of the members.
718 Tue Oct 22 18:04:32 1991 Stu Grossman (grossman at cygnus.com)
720 * infrun.c (wait_for_inferior): Check return value from
723 Mon Oct 21 17:47:03 1991 Stu Grossman (grossman at cygnus.com)
725 * infrun.c (wait_for_inferior): fix stepi/nexti that was broken
726 by my last edit to this routine.
728 Mon Oct 21 14:27:43 1991 John Gilmore (gnu at cygnus.com)
730 * tm-sun3.h (FIX_CALL_DUMMY): problem with cross debugging.
731 FIX_CALL_DUMMY does unaligned accesses and/or forgets to byte swap
732 the values before putting them into the dummy code. (From Peter
735 Mon Oct 21 10:04:39 1991 Steve Chamberlain (steve at rtl.cygnus.com)
737 * configure.in: added ebmon target.
739 Wed Oct 16 22:49:58 1991 John Gilmore (gnu at cygnus.com)
743 * Makefile.in: Roll VERSION to 4.2.
744 * README, TODO, WHATS.NEW: Update.
746 * core.c (core_open): Improve error message for bad file.
747 Pass .reg virtual memory address to fetch_core_registers to help
748 it find the registers in the core-file header.
749 * coredep.c (fetch_core_registers): Take new argument, use it,
750 and pass it to register_addr to locate the block of registers.
751 * xm-mips.h: Update KERNEL_U_ADDR for new scheme. Cleanup a bit.
753 * dbxread.c (read_dbx_symtab, process_one_symbol): Handle
754 Sequent N_FN_SEQ like everybody else's N_FN.
756 * main.c: Circumvent SCO cc bug with #if !!defined(USG).
757 * tm-i386v.h: #endif guck.
758 * xconfig/i386*: Remove -Dgetpagesize()=4096 kludge.
759 * xconfig/i386sco: Add HAVE_STRSTR to avoid ANSI bdeath.
760 * xconfig/tahoe: Add REGEX, which seems to be missing.
762 * coredep.c: Add <sys/types.h> for SCOnix.
763 * dbxread.c (read_dbx_symntab): Avoid coredump on malformed file.
764 * printcmd.c (print_formatted): Flush output before disassembly.
766 Tue Oct 15 20:12:32 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
768 * doc/refcard.tex (sec "Working Files"): consistent metavars and
769 other improvements, due to comments by François Pinard
770 (pinard@iro.umontreal.ca)
772 * doc/gdb.texinfo (appendix "Installing GDB"): changes in
773 configure, and improvenets related to Pinard's refcard comments
775 Tue Oct 15 08:45:12 1991 John Gilmore (gnu at cygnus.com)
777 Changes from Fred Fish:
778 * tm-68k.h (FPI_REGNUM): Add.
779 * infrun.c (child_create_inferior): flush stdout and stderr
781 * configure.in: Handle amigados, amix hosts and targets.
782 * inflow.c: Handle TIOCGLTC_BROKEN for Amiga.
785 * values.c (show_convenience): Use printf_filtered.
786 * main.c (define_command): Check result of lookup_command for
788 (echo_command): Use printf_filtered, and force output out.
790 * dbxread.c (read_enum_type): Avoid Modula-2 kludge that breaks C
792 * i387-tdep.c (double_to_i387): Fix typo for double_to_ieee_extended.
793 * utils.c (_initialize_utils): If !ISATTY, don't paginate.
794 * configure.in, tconfig/decstation, xconfig/decstation: Rename
795 dec3100 to decstation.
797 Mon Oct 14 13:37:50 1991 Roland H. Pesch (pesch at cygnus.com)
799 * doc/gdb.texinfo: Catch up to changes recorded here in ChangeLog
800 (nodes Continuing and Stepping; Memory; Targets) clarifications
803 Fri Oct 11 23:27:06 1991 John Gilmore (gnu at cygnus.com)
805 * tm-{irix3,mips,nindy960,pn,symmetry,vx960}.h: Move
806 REGISTER_U_ADDR to corresponding xm- file. Sugg. by Peter Schauer.
808 * symmisc.c (print_partial_symtabs): Add printpsyms debug cmd.
810 * m68k-tdep.c (m68k_push_dummy_frame, m68k_pop_frame): Add
811 generic routines for calling inferior functions.
813 * blockframe.c (inside_main_scope, inside_entry_scope): New.
815 * copying.awk: Filter formfeeds out of copying & warrantee.
816 Make them available as `show copying' and `show warrantee' also.
817 * main.c (print_gnu_advertisement): Advt `show' commands.
819 Thu Oct 10 17:25:47 1991 John Gilmore (gnu at cygnus.com)
821 * mach386-xdep.c: Even when cross-compiling, leave in the
822 core-file reading code.
823 * core.c (get_core_registers): Avoid coredump if no .reg section.
825 Wed Oct 9 17:03:34 1991 John Gilmore (gnu at cygnus.com)
827 * mipsread.c, coffread.c: initialise TYPE_VPTR_FIELDNO to -1.
828 This avoids coredumps under `set print object on' in value_headof
829 (called erroneously by value_from_vtable_info) for `p &struct'
830 or `p *struct'. From Peter Schauer.
832 Mon Oct 7 00:06:52 1991 John Gilmore (gnu at cygnus.com)
834 * Makefile.in: Roll version to 4.1.2.
835 * dbxread.c: Use aout64.h, not a.out.gnu.h. Get external symbol entry
836 size from BFD (but, FIXME, we don't yet read external nlists's and
837 convert them to internal nlists's before handling them -- we still
838 assume they have the same size and alignment.) Use SET_NAMESTRING
840 * exec.c (exec_file_command): Move dead coff-encapsulation code
842 * m88k-tdep.c, m88k-xdep.c: Remove encap test and #inc <a.out.h>.
844 Fri Oct 4 22:30:06 1991 John Gilmore (gnu at cygnus.com)
846 * configure.in, tm-i386v.h, xm-i386v.h: Intel 386 Mach host port.
847 * xm-i386mach.h, mach386-xdep.c, xconfig/i386mach: New files.
849 Fri Oct 4 17:04:31 1991 Per Bothner (bothner at cygnus.com)
851 More patches from Peter Schauer <pes@regent.e-technik.tu-muenchen.de>:
852 * mips-xdep.c (store_inferior_registers): Don't try to
853 write the (pseudo) FP.
854 * mipsread.c (parse_partial_symbols): Improved algorithm for
855 setting pst->texthigh.
857 Fri Oct 4 16:47:32 1991 Roland H. Pesch (pesch at cygnus.com)
859 * doc/Makefile: make TEXINPUTS include . everywhere
861 Fri Oct 4 00:35:56 1991 John Gilmore (gnu at cygnus.com)
863 * coffread.c, dbxread.c, symfile.c, symmisc.c, symtab.h: Remove
864 vestiges of typevectors, which were for symsegs and are no longer
865 used. (From a question by Eliot Dresselhaus
866 <dresselh@RFT30.nas.nasa.gov>).
868 Thu Oct 3 09:33:26 1991 John Gilmore (gnu at cygnus.com)
870 * dbxread.c, coffread.c: static-ize functions that were
871 gratuitiously external. (From Fred Fish.)
873 * c-exp.y: sym->class to SYMBOL_CLASS (sym).
875 * dbxread.c (dbx_lookup_type): Keep doubling size of typevector
876 until it is large enough.
878 * dbxread.c (read_type): Handle error case slightly better.
879 Make complaint message not C++-specific.
881 Wed Oct 2 17:21:07 1991 Stu Grossman (grossman at cygnus.com)
883 * infrun.c (wait_for_inferior): Fix step/next so that you only
884 stop at the beginning of a new line. This fixes various problems
885 with for loops, nested if-else's and switch statements.
887 Tue Oct 1 06:33:55 1991 John Gilmore (gnu at cygnus.com)
889 * symtab.c (lookup_symtab_1, lookup_symbol): "fatal" errors
890 between symtabs and psymtabs become ordinary error()s.
892 * dbxread.c (read_dbx_symtab): Relocate end_of_text_addr
893 properly, making "end pc" correct in shared lib psymtabs.
894 (From Guy Harris <guy@auspex.com>.)
896 Mon Sep 30 13:15:31 1991 John Gilmore (gnu at cygnus.com)
898 * dbxread.c: Enable, but soften, const_vol_complaint.
899 (read_dbx_symtab): N_STSYM and N_LCSYM define static vars.
900 Ditto Gould N_NBSTS and N_NBLCS. Also, all types in the psymtab
901 should be file-scope, not global.
902 (read_struct_type): Remove ancient multiple-inheritance warning.
903 (read_range_type): Check base type, complain & patch if undefined.
904 * stack.c (frame_info): Demangle the function name in `info stack'.
907 Sat Sep 28 10:02:33 1991 John Gilmore (gnu at cygnus.com)
909 * eval.c (evaluate_subexp_for_address): Don't use
910 TYPE_POINTER_TYPE directly (it might be zero if this type has
911 never had a pointer created before); use lookup_pointer_type.
912 * symtab.c (lookup_method_type): Arguments were swapped in all
913 callers, so fix it here. I'm amazed this worked at all!
915 Fri Sep 27 18:09:31 1991 John Gilmore (gnu at cygnus.com)
917 * c-exp.y, m2-exp.y: Define more yysymbols that happen to be
918 "bss" rather than "data" symbols, but which still conflict.
921 * coffread.c (coff_symfile_read): Use xmalloc, not malloc.
922 * core.c (core_files_info): Shorten output.
923 * exec.c (exec_files_info): Ditto.
924 (build_section_table): Ignore zero-length sections.
925 * language.c, printcmd.c: Lint.
926 * language.h (get_frame_language): Declare.
927 * saber.suppress: update.
928 * stack.c (find_relative_frame): Remove complex code that was
929 #if 0'd, stick with simple code. Lint.
930 * saber.suppress: Update a bit.
931 * symfile.c (add_symbol_file_command): Add "?" to question.
932 * utils.c (parse_escape): Avoid \a due to bdead compilers.
933 * value.h: Declare typedef_print.
935 * valprint.c (val_print, type_print_base): TYPE_CODE_RANGE less
938 * nindy-tdep.c (nindy_frame_chain_valid): Use lookup_misc_func.
939 (Reported by Mark Peek <mark@imagen.com>.)
941 * solib.c (solib_map_sections): Relocate all sections, even
942 though only the text section's size is tracked. Mark ld_text
943 for eventual elimination as we generalize to N sections.
945 * infrun.c (wait_for_inferior): Don't check if the PC is in a
946 call_dummy if we were stopped by a random signal that is being
947 passed to the program. This produced wierd results when calling
948 functions in the inferior and signals (e.g. SIGALRM) were in use.
950 Tue Sep 24 18:05:30 1991 John Gilmore (gnu at cygnus.com)
952 * infrun.c (IN_SIGTRAMP): Not parenthesized properly.
953 Bugfix from Paul Eggert <eggert@twinsun.com>.
954 * tm-ultra3.h (IN_SIGTRAMP): Ditto.
955 * valprint.c (print_floating): Print 9 digits for IEEE floats.
958 Mon Sep 23 15:50:07 1991 John Gilmore (gnu at cygnus.com)
960 * Makefile.in: Roll VERSION to 4.1.1.
961 * source.c (line_info): Peter Schauer fixes a bug I introduced in
964 Fri Sep 20 16:10:52 1991 John Gilmore (gnu at cygnus.com)
968 * Makefile.in (VERSION): Set to 4.1.
969 * language.c (set_language_command): Print useful help message,
970 and restore the language string after giving help.
971 * valprint.c (typedef_print): Print typedef in C or M2.
972 * symtab.c (list_symbols): Use it.
973 * main.c (main): Avoid any output before (gdb) prompt when -q.
974 * language.c (set_language_command): Handle errors by restoring
975 the language string to its current state (fix from A. Beers).
976 * doc/gdbint.texinfo: Roll in information from README. Rearrange
977 "how to install" and "how to print the doc" stuff so it drops
979 * configure.in: Rename rtpc CPU to romp to match config.sub.
980 * README, WHATS.NEW, TODO: Update for gdb-4.1.
982 Fri Sep 20 17:39:14 1991 Roland H. Pesch (pesch at cygnus.com)
984 * doc/gdb.texinfo: Updates from ChangeLog. set/show write,
985 autoloading shared libs, copyright etc on GDB startup, clean up $_
986 and $__ index refs, set/show listsize and related updates to list
987 cmd. New host/target configs.
989 Fri Sep 20 15:46:00 1991 Roland H. Pesch (pesch at cygnus.com)
991 * doc/Makefile: generate aux version-no file doc/gdbVN.m4
992 from main Makefile.in version definition
993 doc/gdb.texinfo: use version recorded in doc/gdbVN.m4 for current
995 Makefile.in (setup-to-dist): generate doc/gdbVN.m4
997 * doc/gdb.texinfo: merge new language-switching and lang-specific
1000 Fri Sep 20 15:00:57 1991 Per Bothner (bothner at cygnus.com)
1002 * mcheck.c: Add __ONEFILE kludge to allow compilation by non-ANSI
1003 compilers (which may lack stddef.h).
1005 Fri Sep 20 13:29:42 1991 John Gilmore (gnu at cygnus.com)
1007 * dbxread.c (read_dbx_symtab, process_one_symbol): N_FN and
1008 N_WARNING are the same except for the N_EXT bit, so just use their
1009 values alone, rather than OR-ing them with N_EXT.
1011 Fri Sep 20 12:27:55 1991 Stu Grossman (grossman at cygnus.com)
1013 * mipsread.c (parse_lines): Deal with negative extended line
1016 * c-exp.y, m2-exp.y: #define yyerrflag and yynerrs to avoid
1017 global symbol conflicts.
1019 Fri Sep 20 02:28:15 1991 John Gilmore (gnu at cygnus.com)
1021 * .gdbinit: Move 'set complaints' to top, so it runs even in
1022 case we aren't debugging GDB.
1023 * language.c (_initialize_language): Fix type check and range
1024 check documentation strings.
1025 * utils.c (!HAVE_VPRINTF): Define vfprintf as a function, so
1026 language.c can use it. (Though language.c should really not be
1027 handling warnings/errors the way it does, FIXME.)
1028 * symtab.c (lookup_primitive_type): const lint.
1030 Bugfix from Peter Schauer:
1031 * source.c (lines_to_list): Make signed, to avoid comparison
1032 going unsigned and complaining that -3 is too high for 21 lines.
1033 * stack.c (lines_to_list): Ditto.
1035 Thu Sep 19 23:33:41 1991 John Gilmore (gnu at cygnus.com)
1037 * Makefile.in (HFILES): Add minimon.h.
1038 (VERSION): Roll version number to 4.0.95.
1039 (gdb.tar.Z, make-proto-gdb.dir, setup-to-dist, gdb-XXX.tar.Z):
1040 New rules for building distributions. Normal distribution
1041 is built by doing `make -f Makefile.in gdb.tar.Z' in the directory
1042 one level up from here; it calls make-proto-gdb.dir to build a
1043 directory `proto-gdb' which is an image of the release. The old
1044 `gdb.tar.Z' rule still works too.
1045 * config.sub, configure: Roll in latest from ..
1047 Thu Sep 19 17:41:24 1991 Roland H. Pesch (pesch at cygnus.com)
1049 * doc/gdbint.texinfo: Reorder contents; reorganize new-host,
1050 new-target, and new-config chapters; fix minor typos; come closer
1051 to usual GNU markup conventions for @file @samp @code @var.
1053 Thu Sep 19 17:04:12 1991 Per Bothner (bothner at cygnus.com)
1055 Patches from Peter Schauer <pes@regent.e-technik.tu-muenchen.de>:
1056 * mipsread.c (parse_partial_symbols): Enter the name of all
1057 structs/unions... into the psymtab so we can access them if the
1058 symtab is not read in.
1059 * mips-tdep.c: Remove some unneeded #includes.
1060 * xconfig/dec3100: Add HAVE_STRSTR.
1062 Thu Sep 19 15:14:23 1991 John Gilmore (gnu at cygnus.com)
1064 * Makefile.in: Circumvent Sun Make bug on *-exp.tab.o.
1065 * c-exp.y, m2-exp.y: Lint.
1066 * m2-exp.y: Avoid using yytname[] which is a Bison-ism.
1067 * valprint.c (val_print_fields): Check for stub type.
1068 * mipsread.c (_initialize_mipsread): Avoid using
1069 builtin_type_void at initialize time.
1070 (mipscoff_symfile_read): use it now.
1072 Wed Sep 18 15:55:51 1991 John Gilmore (gnu at cygnus.com)
1074 Merge multiple-language support, and partial Modula-2 support,
1075 from Andrew Beers <beers@cs.buffalo.edu>.
1077 * i387-tdep.c: New file, consolidates most 80387 support,

1097 (process_coff_symbol): #if 0'd for functions and params as above.
1098 (read_enum_type): Recognize Modula-2 BOOLEAN.
1099 * symtab.c (add_param_to_type): #if 0'd function to add a

1135 TYPE_CODE_BOOL and TYPE_CODE_CHAR.
1137 * expression.h (enum exp_opcode): Add Modula-2 specific opcodes.
1138 * expprint.c: Look up expression opcodes in language-specific

1171 Tue Sep 17 08:37:41 1991 John Gilmore (gnu at cygint.cygnus.com)
1173 Add Andrew Beers' changes for Modula-2 support. His ChangeLog
1174 entries are enclosed herein. Not all of these changes
1175 have been merged into the master GDB sources -- check the
1176 ChangeLog above here for the merge log.
1178 Mon Jun 3 17:05:45 EDT 1991
1180 m2-exp.y Created. Tested outside of GDB for a few days. Proper
1181 operators were added, C specific operators and tokens
1182 removed. yylex() revamped to some extent. Still things
1183 missing from the grammar, such as sets.
1184 Tested for two weeks in GDB v3.5.
1186 Tue Jun 11 17:23:48 EDT 1991
1188 m2-exp.y Added boolean constants TRUE and FALSE to the grammar
1189 so they are built-in. Sort of a hack.
1191 Fri Jun 14 12:53:51 EDT 1991
1193 m2-exp.y Added range checking for numeric constants. Any numeric
1194 constant is assumed to be of builtin type INTEGER unless:
1195 (1) it is octal or hexadecimal, in which case it is a
1196 CARDINAL; (2) it is too big to fit into an INTEGER, in
1197 which case it is a CARDINAL.
1198 eval.c Added simple range checking for +, -, and * on integers.
1199 Doesn't work very well for *, since 6 * 1,000,000,000 =
1200 1,705,032,704, which fails the simple test of result >=
1201 first_operand, no matter in what order the operands are.
1203 Tue Jun 18 14:11:30 EDT 1991
1205 Broke the parser into parts, one containing the C grammar and the other
1206 containing code to be shared by all of the grammars.
1208 The following files no longer exist:
1213 The following files were added:
1215 c-exp.y (The C grammar)
1216 m2-exp.y (The Modula-2 grammar)
1217 parser-code.c (Code that is shared by the above grammar)
1221 Makefile.dist Changed to reflect the above dependencies. NOTE: It is
1222 now necessary to use the Bison compiler compiler, since it
1223 will generate function/variable prefixes other than yy.
1225 Tue Jun 18 16:47:49 EDT 1991
1227 symtab.[ch] Added the external variable working_lang, than holds the
1228 value of the current working language.
1229 Added the ennumerated type language_mode, with the values
1230 language_auto and language_manual, the former meaning that
1231 GDB sets working_lang as needed, and the latter meaning
1232 that the value of working_lang is totally under user
1234 symtab.[ch] Added the Modula-2 pervasive types INTEGER, CARDINAL,
1235 REAL, BOOLEAN and CHAR. Also added the type codes
1236 TYPE_CODE_BOOL and TYPE_CODE_CHAR.
1237 utils.c Added set_language_command and show_language_command to
1238 implement the GDB support commands "set language" and
1240 expression.h A number of identifiers were added to the type exp_opcode
1241 to facilitate Modula-2 builtin functions, integer
1242 division, and array indexing.
1244 Wed Jun 19 13:25:58 EDT 1991
1246 language.h Added the macro STRICT_TYPE, which evaluates to non-zero
1247 if the language specified by working_lang requires the use
1248 of strict typing of expressions. Eventually, even this
1249 will be able to be changed by the user.
1250 Added the macro RANGE_CHECK, which evaluates to non-zero
1251 if the language specified by working_lang requires the
1252 checking of a value against the domain of its type.
1253 Eventually, even this will be able to be changed by the
1255 language.[ch] Predicates involving types (simple_type, ordered_type,
1256 same_type, integral_type, numeric_type, character_type,
1257 boolean_type, float_type) are added. These predicates are
1258 based on the current value of working_lang, and are handy
1261 Wed Jun 19 15:39:34 EDT 1991
1263 eval.c Added the function type_array_rank which computes the rank
1265 valarith.c Added the funtion value_bool, which when given a integer
1266 value.h value (ie. struct value *) as an argument, it returns a
1267 boolean value (ie. struct value *) true if that integer
1268 is non-zero, and a boolean value false otherwise.
1269 valprint.c Added cases for TYPE_CODE_BOOL, so Modula-2 BOOLEAN values
1270 will print out properly.
1272 Wed Jun 19 16:36:34 EDT 1991
1274 valops.c Added the function value_capitalize, which returns it
1275 value.h argument capitalized if its argument is a lowercase
1276 letter, or the argument unchanged if its argument is not a
1278 valarith.c Added the function range_check_p, which returns non-zero
1279 value.h if its value argument is between the integral bounds upper
1281 Added the function range_check_enum_p, which makes sure
1282 that its value argument is a valid member of the domain of
1284 Added the function range_check_range_p, which makes sure
1285 its value argument lies between the upper and lower bounds
1286 of its type argument, which must be a ranged type.
1287 Added the function check_array_index, which range and type
1288 checks an index of an array.
1289 Added the function value_multi_subscript, which computes
1290 array[idx1,idx2...idxN], given a value array and an array
1291 of values representing indicies.
1292 values.c Changed value_from_long to work with TYPE_CODE_CHAR and
1293 unpack_long to work with TYPE_CODE_BOOL and
1296 Wed Jun 19 18:04:08 EDT 1991
1298 symtab.c Stored pervasive types in a structure and make
1299 lookup_pervasive_type() a lookup function that was based
1300 on working_lang. If lookup_pervasive_type() returned
1301 non-zero, then that value was returned (a fix, since
1302 before it simply wouldn't return the pervasive type.)
1303 language.h Added the macro CAST_IS_CONVERSION, which evaluates to
1304 non-zero if the language specified by working_lang means
1305 "conversion" when it says "cast".
1306 valops.c Added the function value_real_cast(), which performs a
1307 value.h *cast*, not a *conversion*, which is what value_cast()
1308 does when it can. In particular,
1309 value_cast(<float_type>,4) = 4.0, while
1310 value_real_cast(<float_type>,4) = some mess.
1311 eval.c Modula-2 builtin functions implemented: ABS, CAP, CHR,
1312 parser-code.c FLOAT, HIGH, MAX, MIN, ODD, ORD, TRUNC, and VAL.
1313 expression.h Added macros MAX_OF_TYPE and MIN_OF_TYPE to work with MAX
1314 and MIN on integral types. *NOTE*: These are currently
1315 hardcoded to work only if there are 8 bits per storage
1317 eval.c Made logical functions call value_bool to return a
1318 properly typed boolean value, based on working_lang.
1320 Thu Jun 20 11:55:27 EDT 1991
1322 valprint.c Types now print out in a Modula-2 fashion. This works for
1323 the cases when the type is printed out step-by-step, that
1324 is, it doesn't work when the name of a structured type
1325 (which includes the keyword "struct", etc.) is simply
1327 FIXME: Perhaps this is bad. Parts of it seem to kludgey,
1328 since type specifications in C and Modula-2 are very
1329 different. The C printing of a type is very recursive,
1330 whereas in Modula-2 it is generally very simple. C has
1331 type prefixes and suffixes, which have no real analogue in
1332 Modula-2. Maybe type_print() should call a language
1333 specific type printer. This is also advantageous if we
1334 compile GDB to exclude some of the languages. We'll just
1335 leave those functions out.
1337 Thu Jun 20 16:57:10 EDT 1991
1339 dbxread.c When reading the complete symbol table in (via
1340 psymtab_to_symtab()), the number and types of function
1341 arguments are added to a function type. define_symbol()
1342 calls add_param_to_type() to accomplish this.
1343 Assumption: when we come across a function definition
1344 (N_FUN symbol with an 'f' or 'F' in the name), its
1345 arguments will appear before another function definition.
1346 When a function is found, a pointer to its type is placed
1347 in the global in_function_type. Changes that
1348 add_param_to_type() makes are to this global.
1349 valprint.c The type of a function now includes (for Modula-2) the
1350 types of its parameters.
1351 eval.c Type checking and a check for the proper number of
1352 arguments is now done for function calls. Not sure of the
1353 impact this has on C++ member function yet.
1355 Thu Jun 20 19:58:48 EDT 1991
1357 valprint.c Rewrote the type printer. Broke it into two language
1358 specific parts, adding the functions type_print_m2() and
1360 An unfortunate consequence is this: if you debugging a C
1361 program in Modula-2 mode (why?), info types does not work
1362 well with regular expressions, since the types are printed
1363 out in Modula-2 terminology, but stored in C terminology.
1364 language.[ch] Added the functions new_type_last(), type_keyword(), and
1365 type_sep() to aid in the printing of typedefs.
1366 symtab.c Made the printing of typedefs as language independent as
1367 possible through calls to new_type_last(), type_keyword(),
1370 Fri Jun 21 11:50:26 EDT 1991
1372 dbxread.c Check all incoming ennumerated types. If it looks like
1373 Modula-2's BOOLEAN type, then change the type_code of the
1374 type to TYPE_CODE_BOOL so we can process it as a boolean
1376 valprint.c Replaced some of the 0x%x with calls to sprintf and
1377 hexformat() in val_print().
1378 language.[ch] Added the function hex_to_string(), which converts its
1379 integral argument to a hexadecimal number (format is
1380 language based) and returns the result as a string.
1382 Mon Jun 24 12:25:07 EDT 1991
1384 valprint.c Some functions call type_print_1() directly, instead of
1385 value.h using type_print(), so they can specify where (column) to
1386 print things. Since type_print() takes care of language
1387 dependence, that needs to be called first. Added a
1388 parameter depth to type_print() (so it is now like
1389 type_print_1). Changed type_print to type_print_at, and
1390 made type_print a macro that passes a depth argument of
1392 symmisc.c Changed all calls to type_print_1 to calls to
1394 Makefile.dist Made it possible to build GDB for a specific set of
1395 depend languages. Do this by passing a definition for the macro
1396 LANGS to make. LANGS should be a string containing a
1397 space-separated list of language names (ie. LANGS="c m2").
1398 The default is to build all languages. Note that grammar
1399 files must follow the naming convention of <lang>-exp.y.
1400 gdb.lang This holds the current value of the LANGS macro. It is
1401 examined every time make is called, and is updated if
1403 eval.c Added #ifdef _LANG_<lang> to these files.
1404 expread.c Still need to add them to dbxread.c and coffread.c.
1412 Mon Jun 24 16:33:11 EDT 1991
1414 language.[ch] Added the functions hexformat_pre() and
1415 hex_to_string_pre(), which take a prefix argument to
1416 include in the format string. Thus, hexformat_pre("08") will
1417 return "0x08x" (if the working language is language_c).
1418 Made hexformat() and hex_to_string() calls to the above
1419 with "" as the prefix argument.
1421 am29k-pinsn.c, arm-pinsn.c, breakpoint.c, convex-tdep.c, exec.c, core.c,
1422 dbxread.c, i386-pinsn.c, i386-stub.c, i386-xdep.c, i960-pinsn.c,
1423 infcmd.c, inflow.c, m68k-pinsn.c, m68k-stub.c, m88k-pinsn.c,
1424 mips-pinsn.c, mips-tdep.c, ns32k-pinsn.c, printcmd.c, pyr-pinsn.c,
1425 pyr-tdep.c, pyr-xdep.c, remote-vx.c, remote.c, solib.c, source.c,
1426 stack.c, sun386-xdep.c, symfile.c, symm-xdep.c, symmisc.c, tahoe-pinsn.c,
1427 valprint.c, vax-pinsn.c
1429 Changed all occurences of 0x%[0-9]*l*x in printf format strings to
1430 calls to hexformat() and hex_to_string(). Format strings without
1431 the leading "0x" were ignored.
1433 depend Updated to take the above into account.
1436 Tue Jun 25 15:27:18 EDT 1991
1438 symtab.h Added the types range_mode_t, range_check_t, type_mode_t,
1439 and type_check_t to keep track of the current state of
1440 range and type checking.
1441 main.c Added the variables range_mode, range_check, type_mode,
1442 and type_check to record the current state of range and
1443 type checking. Added initialization code to main().
1444 language.h Changed the macros STRICT_TYPE and RANGE_CHECK to examine
1445 the above variables.
1448 Tue Jun 25 17:57:08 EDT 1991
1450 dbxread.c process_one_symbol() updates the variable (enum language)
1451 source_lang based on the extension of the filename
1452 contained in the N_SO sybmol that started this symtab.
1453 When end_symtab() is called, the value of source_lang is
1454 put into the language field.
1455 stack.c select_frame() sets working_lang (and possibly type_check
1456 and range_check) to the language field of the symtab
1457 associated with the frame that is selected if working_mode
1458 is language_auto. If working_mode is language_manual, a
1459 warning is printed and working_lang is not set.
1460 language.c Added the function set_type_range(), which sets the value of
1461 type_check and range_check (if their modes call for
1462 automatic setting) based on the current value of
1463 working_lang. A non-zero argument will cause the current
1464 settings to be output.
1467 Wed Jun 26 14:51:40 EDT 1991
1469 eval.c Added range checks on assignment.
1470 m2-exp.y Added the grammar for sets to the language. Currently,
1471 these do not do anything except print an error message.
1473 Wed Jun 26 17:01:04 EDT 1991
1475 m2-exp.y Added the ability for parse_number() to parse negative
1476 numbers. A global flag is set upon encountering a unary
1477 minus. This was done to make, for example, 1 parse as a
1478 CARDINAL, and not as an integer, per Wirth's examples in
1479 Programming in Modula-2 ed.4.
1480 valprint.c Added support for "set radix 2" by then setting
1481 output_format to 't'.
1482 eval.c Implemented range checking on subrange types. Added calls
1483 to range_check_range_p for BINOP_ASSIGN and BINOP_VAL.
1484 Implemented MIN and MAX for ennumerated types. The
1485 minimum value of an ennumerated type is defined by Wirth
1486 as the first identifier, and the maximum as the last.
1487 m2-exp.y Made octal numbers ending with "B" be characters and those
1488 ending with "C" be numbers, per Wirth's book. (p. 34)
1490 Thu Jun 27 14:11:52 EDT 1991
1492 stack.c select_frame() now only sets working_lang, it does not
1493 notify the user. If working_mode is language_manual, then
1494 a warning is issued once.
1495 main.c At the end of each call to execute_command(), working_lang
1496 is checked against the local static (enum language)
1497 current. If they differ and working_mode is
1498 language_auto, the new settings of language, type and
1499 range checking are printed out.
1500 stack.c Modified frame_info() to include the language of the
1501 current frame in the output of "info frame".
1502 language.[ch] Added the function language_str() which returns the name
1503 of the current language.
1505 Fri Jun 28 15:33:14 EDT 1991
1507 m2-exp.y Added the built-in procedures INC, INCL, DEC, and DECL to
1508 the language. INCL and DECL currently cause an error,
1509 since sets are not implemented yet. INC and DEC are
1510 implemented as PREINCREMENT/PREDECREMENT with one
1511 argument, and as ASSIGN_MODIFY with two arguments.
1512 eval.c Added type checking to the above cases.
1513 value.h Added not_lval_constant to the lval_type ennumerated type.
1514 not_lval_constant means that the value is a constant
1515 value; that is 3 or 'a' or TRUE, not as in a constant
1516 identifier. This is used to help coerce numbers such as 3
1517 to either signed or unsigned numbers.
1518 valops.c Added the function value_coerce_constants() which coerces
1519 constant integers as following: if one is a constant and
1520 the other is not, the constant's type is set to the type
1521 of the other argument. If both are constants and one is
1522 signed, the other is converted to a signed constant.
1524 Sat Jun 29 17:26:29 EDT 1991
1526 valarith.c Added a better range checker. It now checks range
1527 (successfully) on integral operations [+-] (signed and
1528 unsigned) for any C sized type. Still does not work well
1529 for multiplication.)
1530 int_in_size() returns an integer that is coerced to fit into
1531 specified number of bytes.
1533 Mon Jul 1 13:04:14 EDT 1991
1535 language.[ch] Added the function binop_result_type(), which returns the
1536 builtin (struct type *) type that would be the result of a
1537 binop on the two values V1 and V2.
1539 Wed Jul 3 19:22:53 EDT 1991
1541 source.c Extended source_info() to include the source language in
1542 the output from "info source".
1544 Fri Jul 5 13:48:52 EDT 1991
1546 utils.c Moved the support functions for the GDB set/show commands
1547 dealing with language into language.c.
1548 language.c Added the function language_info(), which displays info
1549 about the current working language, type and range check
1550 settings. Called via the GDB command "info language".
1551 Added an initialization routine _initialize_language(),
1552 that sets defaults for the language, type and range
1553 variables and sets up the new GDB commands.
1554 main.c Language setup moved to language.c.
1557 Mon Jul 8 10:10:22 EDT 1991
1559 valarith.c Debugged the range checker for arithmetic. Still does not
1560 work for multiplication very well.
1562 Mon Jul 8 12:40:37 EDT 1991
1564 language.[ch] Added the function value_true() which returns non-zero if
1565 its argument represents a boolean true value.
1566 breakpoint.c Changed breakpoint_cond_eval() to call value_true() to
1567 check the truth of an expression.
1569 Thu Jul 11 12:51:34 EDT 1991
1571 language.[ch] Added the predicate structured_type(), which returns
1572 non-zero if the argument is a structured type.
1573 Added the predicate pointer_type(), which returns non-zero
1574 if the argument is a pointer type.
1575 eval.c Added the ability to do addition and substraction on
1576 pointers and integers. This case simply bypasses the
1579 Thu Jul 11 14:41:42 EDT 1991
1582 Added the symbol N_DEFD (0x4a) which is a definition
1583 module dependency that is used by the GNU Modula-2
1584 compiler and the linker. It is not important to GDB,
1585 except that [dbx|coff|mips]read.c should ignore these
1588 Fri Jul 12 16:07:00 EDT 1991
1590 valprint.c Changed the TYPE_LENGTH(type) >= 0 to TYPE_LENGTH(type) >
1591 0 in val_print(). Also added statements to the else part
1592 to coerce type (argument to val_print) to a pointer type
1593 if it is an "array of unspecified length".
1594 valops.c Added the function value_m2_string(), which returns a
1595 (value) value which is a constant string, whose type is
1596 (ARRAY [0..n] OF CHAR). The length field of the type
1597 structure is set to zero, so it will be interpreted as an
1598 "array of unspecified length".
1599 stack.c Moved the language/frame mismatch check to
1600 main.c:execute_command().
1601 main.c The working language is recorded each time
1602 execute_command() is executed. If working lang has
1603 changed during its execution, then the new
1604 language/type/range info is printed out for the user. If
1605 the working language does not match the language of the
1606 frame, a warning is issued.
1608 Sat Jul 13 16:16:39 EDT 1991
1610 eval.c Moved all the type-checking stuff for operators to
1611 language.[ch] language.c. This is so we can keep language-specific
1612 stuff (like for what type operators are defined) in
1614 language.[ch] Added the function binop_type_check(), which checks to see
1615 if its two (value) arguments are type-compatible with its
1616 opcode argument. The opcode should represent an operation
1617 involving an operator. Also added the macro function
1618 unop_type_check, which calls binop_type_check with a
1619 NULL second argument.
1620 expprint.c Added Modula-2 operators to the op_print_tab, so info
1621 expression.h break works correctly. Also added "op_string", which
1622 returns the string corresponding to the (enum exp_opcode)
1623 opcode that is its argument.
1626 Sat Jul 13 18:26:18 EDT 1991
1628 coffread.c Added code to record the type of function arguments with
1629 each paricular function. Code is very similar to that
1631 dbxread.c Moved add_param_to_type() to symtab.c
1632 symtab.[ch] Added function add_param_to_type() from dbxread.c
1634 *** NOTE: The above additions have not been tested.
1636 Mon Jul 15 12:50:47 EDT 1991
1638 langauge.[ch] Added the functions type_error and range_error, which work
1639 like error() except if the type/range mode is set to
1640 *_mode_warn, then they do not do a return_to_top_level(),
1641 but merely print a warning.
1642 Also changed [set|show]_[type|range]_command() to support
1643 the new "warn" feature.
1645 Thu Jul 18 17:50:54 EDT 1991
1647 mipsread.c Added code to record the type of function arguments with
1648 each particular function. Code is very similar to that
1651 *** NOTE: The above additions have not been tested.
1653 Fri Jul 19 11:19:10 EDT 1991
1655 defs.h Added macros MAX_OF_SIZE, MIN_OF_SIZE, UMAX_OF_SIZE, and
1656 UMIN_OF_SIZE, which when given a size of a numeric type,
1657 return the maximum and minimum value it can hold. UMAX...
1658 and UMIN... return the result for unsigned types.
1659 symtab.h Added the macros MAX_OF_TYPE and MIN_OF_TYPE to operate on
1660 struct types. They call above macros.
1661 dbxread.c Renamed the MAX and MIN_OF_TYPE macros to ..._OF_CTYPE to
1662 avoid a name conlict with the above.
1663 c-exp.y Added range checking on numeric constants in
1664 parse_number() for completeness.
1665 valarith.c Made binop_user_defined_p() and unop_user_defined_p()
1666 return 0 if working_lang is not language_c.
1668 Thu Aug 8 14:17:22 EDT 1991
1672 breakpoint.c Documentation strings of some commands changed to
1673 eliminate the references to the C language where
1676 Tue Aug 13 15:48:03 EDT 1991
1678 m2-exp.y Added qualified identifiers to the grammar. The semantics
1679 are slightly different from those of the GDB operator ::
1681 m2-exp.y Added a rule to each grammar of the form: start ::= exp |
1682 type_exp, where type_exp is any valid type expression.
1684 eval.c Added the opcode OP_TYPE, and an error case in eval.c.
1685 printcmd.c Modified ptype_command() so it actually parses the input
1686 (necessary for type expressions with scope qualifiers).
1687 Added the function ptype_eval() which expects an
1688 expression composed of one OP_TYPE element.
1689 *.[ch] Replaced all occurences of parse_c_expression with
1691 *.[ch] Replaced all occurences of parse_c_1 with parse_exp_1
1693 [End of ChangeLog entries from Andrew Beers for Modula-2 support.]
1695 Mon Sep 16 17:19:46 1991 John Gilmore (gnu at cygnus.com)
1697 Small fixes from Peter Schauer:
1699 * infrun.c (child_attach): Lint.
1700 * solib.c (find_solib): Handle shared libs version 2.
1702 Small fixes from David Wood:
1704 * xm-ultra3.h (SYS_SIGLIST_MISSING): Typo.
1708 * remote-vx.c: Move <stdio.h> to top, for FILE. Fix from
1709 John S <basrai%kanga.dnet@c3po.sm-alc.af.mil>.
1711 * utils.c (wrap_here): Avoid wrap action of fputs_filtered if
1712 chars_per_line is at maximum (user typed `set width 0'). Fix
1713 from Andreas Schwab <schwab@ls5.informatik.uni-dortmund.de>.
1715 Tue Sep 17 17:31:04 1991 Stu Grossman (grossman at cygnus.com)
1717 * coredep.c: include ptrace.h where necessary.
1718 * mipsread.c(parse_lines): fix unsigned char problem that was
1719 messing up line numbers on SGI's and possibly other MIPS based
1721 * infrun.c (child_create_inferior): use better test to check
1722 return val from setpgrp().
1723 * tm-irix3.h, xm-irix3.h, tconfig/irix3, xconfig/irix3: add these
1724 for sgi/irix support.
1726 Wed Sep 18 04:33:31 1991 Per Bothner (bothner at cygnus.com)
1728 * mipsread.c (parse_symbol): Put non-static procedures
1729 in the global block.
1731 Fri Sep 13 00:14:52 1991 John Gilmore (gnu at cygnus.com)
1733 Patch together `text_start' and `text_end' for 29K port.
1735 * exec.c (exec_command): If NEED_TEXT_START_END, define the
1736 variables and set them based on the exec file.
1737 * am29k-tdep.c: declare text_start.
1738 * valops.c (call_function_by_hand): declare text_end.
1740 * inferior.h: Eliminate CANNOT_EXECUTE_STACK in favor of
1741 defining CALL_DUMMY_LOCATION as BEFORE_TEXT_END. This is
1742 because machines that do this will also have to know to
1743 set NEED_TEXT_START_END. Besides, it was a redundant way to
1745 * tm-29k.h, tm-convex.h, tm-np1.h: Eliminate
1746 CANNOT_EXECUTE_STACK, define CALL_DUMMY_LOCATION and
1747 NEED_TEXT_START_END.
1749 Thu Sep 12 00:22:24 1991 John Gilmore (gnu at cygint.cygnus.com)
1751 AMD 29000 changes from David Wood <wood@david.ultra.nyu.edu>:
1753 * Makefile.in (CLIBS): Put XM_CLIBS and TM_CLIBS at end.
1754 Pass MUNCH_DEFINE to munch whenever we run it.
1755 * am29k-pinsn.c (print_insn): Handle NOP specially. Avoid %#x
1756 format string; use 0x%x instead.
1757 * am29k-tdep.c: Use DUMMY_SAVE_GREGS and RETURN_REGNUM.
1758 * ultra-xdep.c, xm-ultra.h: New files for Ultracomputer host system.
1759 * xm-rtbsd.h: New host support for RT/PC running BSD Unix.
1760 * inflow.c: Handle `short' process group IDs.
1761 * infptrace.c (fetch_register): Support CANNOT_FETCH_REGISTER,
1762 and check for ptrace errors.
1763 * coffread.c (SDB_REG_TO_REGNUM): Define if not already.
1764 (coff_symfile_init): Initialize text_bfd_scnum.
1765 (read_coff_symtab): Use it to find the text [and absolute?] sections.
1766 * ../config.sub: Add vendor nyu and os "sym[1-9]*".
1767 * configure.in: Add hosts rtpc-*-* and a29k-*-*.
1768 Merge target arm case with other "easy" cases. Add target
1769 cases a29k-*-none (rehack of am29k), a29k-*-kern (remote to
1770 Ultracomputer kernel), and a29k-*-sym1 (ultracomputer OS's user
1772 * minimon.h, remote-adapt.c, remote-mm.c: Add.
1773 * munch: Cope with RT/PC putting fns in data segment.
1774 Restore ability to override `nm' by specifying MUNCH_NM.
1775 * xconfig/rtbsd, xconfig/ultra3: New host systems.
1776 * tconfig/a29k: Rename from tconfig/am29k. Add remote-mm
1777 and remote-adapt. Remove encapsulated coff #define's (the
1778 support should go in BFD, and gdb shouldn't know or care).
1779 * tconfig/a29k-kern: Same, but for remote kernel debugging.
1780 * tconfig/ultra3: For debugging user processes on Ultra3/Sym1.
1781 * tm-29k.h: Update BADMAG (though it should go away).
1782 Allow the register definitions to be overridden in another
1783 tm-file. Fix SR_REGNUM. Add a mess of _REGNUM's. Separate
1784 RETURN_REGNUM from GR96_REGNUM and DUMMY_SAVE_GREGS from
1785 DUMMY_SAVE_GR96, for handling kernel calling conventions
1786 that use GR64+ rather than GR96+.
1787 * tm-ultra3.h: New file, for use on Ultra3 Unix as well as for
1788 remote debugging of Ultra3 kernel. Includes tm-29k.h and
1789 overrides various things.
1791 * remote-mm.c (mm_attach, mm_wait): Handle attach like
1792 child_attach does, making a clean stop in the newly attached
1794 * remote-eb.c: Lint.
1796 * coffread.c: Make coffread independent of any particular
1797 variant of COFF. Avoid #include-ing any particular one except
1798 internalcoff.h. BFD now passes key values for symbol reading
1799 as part of its coff_data structure (LINESZ, SYMESZ, AUXESZ,
1800 and the symbol masks and shifts); use them.
1801 Remove obsolete end_of_text_addr.
1803 * exec.c: Remove unused include files.
1805 Wed Sep 11 19:38:44 1991 John Gilmore (gnu at cygint.cygnus.com)
1807 * Makefile.in (documentation targets): Pass $(M4).
1808 Bugfix from eggert@twinsun.com (Paul Eggert).
1810 * stack.c (down_silently_command): Check for stack existence.
1812 Tue Sep 10 23:08:29 1991 John Gilmore (gnu at cygint.cygnus.com)
1814 * Makefile.in (VERSION): Update to 4.0.3.
1816 Tue Sep 10 09:19:29 1991 John Gilmore (gnu at cygint.cygnus.com)
1818 * core.c (core_file_command): Print frame at coredump with
1819 its level number, by calling print_stack_frame.
1820 * frame.h: Add selected_frame_level, print_stack_frame.
1821 * frame.h, stack.c: Remove print_sel_frame, print_selected_frame.
1822 * convex-tdep.c, convex-xdep.c, infcmd.c, inflow.c, infrun.c:
1823 Change print_sel_frame and print_selected_frame callers to
1826 * dbxread.c (read_ofile_symtab): Avoid empty else clause.
1827 * symfile.c (free_named_symtabs): Ditto.
1828 * main.c (main): wrap_here needs an arg.
1829 * solib.c (find_solib): Avoid memory access if _DYNAMIC is zero.
1830 (solib_add): Avoid noise.
1831 (solib_create_inferior_hook): Lint.
1832 (sharedlibrary_command): Move dont_repeat to here.
1833 * utils.c (error): Call wrap_here to force buffered output.
1835 Small patches from Peter Schauer:
1837 * coffread.c (start_symtab): Free any existing line_vector before
1839 (read_coff_symtab): Ditto for type_vector.
1841 * source.c (lines_to_list): New variable, replacing function.
1842 (all uses): Use as variable.
1843 (_initialize_source): Add 'set listsize' and 'show listsize'.
1844 * utils.c (lines_to_list): Remove function.
1845 * stack.c (print_frame_info): Use as variable.
1846 * defs.h (lines_to_list): Remove declaration.
1848 Mon Sep 9 13:45:57 1991 John Gilmore (gnu at cygint.cygnus.com)
1850 * breakpoint.c (insert_breakpoints): Restore warning about
1851 the program might be running in another process, but only for
1852 systems with this brain death (#ifdef ONE_PROCESS_WRITETEXT).
1853 * xm-hp300bsd.h, xm-mips.h, xm-vax.h: Define it.
1855 * utils.c (error): if error_pre_print is set, print the string
1857 * main.c (main, print_gnu_advertisement, print_gdb_version):
1858 Reformat legalese so it always prints, but acts as an "I'm here"
1859 message while symbols are being read. If any errors occur,
1860 print a few newlines to set off the message and start it at the
1861 left margin. Remove mention of "help" command, and don't yak
1862 about symbol reading.
1863 (catch_errors): Error string is now printed first in case of
1865 * command.c (undef_cmd_error, lookup_cmd): On undefined command,
1866 suggest the "help" command.
1868 * Makefile.in (VERSION): Set to 4.0.2.
1870 Thu Sep 5 23:49:48 1991 John Gilmore (gnu at cygint.cygnus.com)
1872 * .gdbinit: Remove useless "rr" command. Set complaints
1873 to 1 for people debugging gdb.
1875 * breakpoint.c, remote-vx.c: Reword strings printed by
1876 catch_errors callers.
1878 Wed Sep 4 11:07:50 1991 John Gilmore (gnu at cygint.cygnus.com)
1880 * WHATS.NEW: "history write -> history save". Doc "write on/off".
1881 (Fix from kenc@viewlogic.com.)
1883 Fix some infrastructure to be able to cope with host and target
1884 machines with different sized basic types (ints, ptrs, etc).
1885 (Idea from pierre@la.tce.com (Pierre Willard).)
1887 * values.c (value_from_longest): Rename from value_from_long.
1888 Handle pointer types as well as integers, so that targets with
1889 different pointer sizes from the host can be accomodated.
1890 * breakpoint.c, convex-tdep.c, eval.c, expprint.c, printcmd.c,
1891 valarith.c, valops.c, valprint.c, value.h, values.c: Rename
1892 uses of value_from_long to value_from_longest.
1893 * eval.c, findvar.c, printcmd.c, valarith.c, valops.c: Pass
1894 the correct pointer type to value_from_long{est}.
1896 * doc/gdb.texinfo ($_, $__): Describe types of these variables.
1898 * remote-vx.c: Remove obsolete code for calling functions via
1899 vxworks kludge interface (it referenced value_from_long).
1901 * valops.c (value_string): Find malloc with lookup_misc_func, not
1904 Tue Sep 3 18:37:46 1991 John Gilmore (gnu at cygint.cygnus.com)
1906 Make writing to files work properly. (Fixes to BFD are also needed.)
1908 * core.c (core_open): Open file ourselves, read or r/w, depending on
1909 write_files. Use bfd_fdopenr.
1910 * gdbcore.h (write_files): New variable.
1911 * exec.c (write_files): Define variable, add set&show for it.
1912 (exec_file_command): Use write_files to open for read or r/write.
1914 Make shared library reading happen automatically. These changes
1915 are mostly from Peter Schauer <pes@regent.e-technik.tu-muenchen.de>.
1917 * inferior.h (stop_soon_quietly): Add to exported variables.
1918 * infrun.c (child_create_inferior): call solib hook, if defined.
1919 (child_attach): call solib hook, if defined.
1920 * solib.c: Include inferior.h. Add from_tty to so_list as kludge.
1921 (find_solib): Use lookup_misc_func rather than hand-rolled.
1922 (symbol_add_stub): New stub for catch_errors.
1923 (solib_add): Avoid output if !from_tty. Catch errors rather
1924 than just calling symbol_file_add and bombing.
1925 (solib_create_inferior_hook): Interface with the target process
1926 to let it read and alloc shared libs, then figure out what it did.
1928 * core.c (validate_files): Fix typo, soften warning.
1929 (Fix from Hiroto Kagotani <kagotani@cs.titech.ac.jp>.)
1931 * utils.c (fputs_demangled): Avoid duplicate printing if
1932 demangling is off. (Fix from J.T. Conklin <jtc@cayenne.com>.)
1934 * infrun.c (proceed): Cast -1 to (CORE_ADDR) before comparing.
1935 (Fix from pierre@la.tce.com (Pierre Willard).)
1937 * main.c (catch_errors): Change argument to a char * from an int,
1938 since a char * can point to a struct full of glop, but an int
1939 is not guaranteed to be able to hold a pointer.
1940 * breakpoint.c (breakpoint_cond_eval, bpstat_stop_status,
1941 breakpoint_re_set_one, breakpoint_re_set): Adapt.
1942 * core.c (core_open, solib_add_stub): Adapt.
1943 * remote-vx.c (symbol_stub, add_symbol_stub, callers): Adapt.
1945 Wed Aug 28 18:18:05 1991 John Gilmore (gnu at cygint.cygnus.com)
1947 * Makefile.in: Update VERSION to 4.0.1. Evade GNU Make bug
1948 by adding .NOEXPORT target.
1950 Fri Aug 23 17:14:25 1991 John Gilmore (gnu at cygint.cygnus.com)
1954 * Makefile.in (VERSION): Roll to 4.0.
1955 (gdb.tar.Z): Make refcard.ps as well, for shipment.
1957 Fri Aug 23 14:07:09 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1959 * doc/gdb.texinfo: minor rewordings, crossref to ptype from print,
1962 * doc/Makefile, Makefile.in: generate "gdb-all.texi" rather than
1965 * doc/rdl-apps.texi: renamed from rdl-apps.texinfo
1967 * Makefile.in, doc/Makefile, doc/.Sanitize, doc/gdb.texinfo:
1968 reflect above name change
1970 * WHATS.NEW: correct pointer to refcard.
1972 * doc/gdb.texinfo: update New Features, Installing
1974 * doc/gdbint.texinfo: add short description of configure +template
1976 Fri Aug 23 11:46:08 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1978 * doc/gdb.texinfo: update, fix bugs in "Installing" appendix
1980 Fri Aug 23 01:02:00 1991 John Gilmore (gnu at cygint.cygnus.com)
1982 * Makefile.in: Add config.sub, make doc/rdl-apps.texinfo for
1983 tar file, add dependencies for referenced doc files.
1985 Thu Aug 22 22:17:06 1991 Stu Grossman (grossman at cygint.cygnus.com)
1987 * coffread.c, symfile.c, stack.c: saberized.
1989 Thu Aug 22 16:20:27 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1991 * doc/refcard.tex: permuted Essential Commands sec
1993 * doc/gdb.texinfo: new C++ chapter; revised installation appendix;
1995 set/show symbol-reloading
1996 default set complaints 0
1998 RET-repeat disabled after prompted long displays
1999 processID (attach) interpretation of 2nd GDB cmdline arg
2001 Thu Aug 22 14:05:47 1991 Stu Grossman (grossman at cygint.cygnus.com)
2003 * expread.y, coffread.c, dbxread.c, target.c, mem-break.c,
2004 cplus-dem.c, values.c, valprint.c, symfile.c, remote.c,
2005 breakpoint.c, main.c: lint.
2007 Thu Aug 22 02:02:26 1991 John Gilmore (gnu at cygint.cygnus.com)
2009 Install new configuration scheme for GDB and friends.
2011 * config.sub: Translate ordinary names to three-part names.
2012 * configure: Use three-part names internally.
2013 * configure.in: Translate three-part names to filenames.
2015 * README, WHATS.NEW: Update for gdb-4.0.
2016 * Makefile.in: Roll VERSION to 3.99.
2018 Wed Aug 21 18:21:09 1991 John Gilmore (gnu at cygint.cygnus.com)
2020 * infptrace.c (KERNEL_U_ADDR_BSD): Include a.out.gnu.h.
2021 * i960-tdep.c, m68k-tdep.c, sparc-tdep.c, tm-i960.h,
2022 tm-m68k.h, remote-nindy.c: Change ext_format_XXX structs
2023 to single structures rather than arrays; when passing
2024 their address, use &. This avoids trouble with bdead compilers.
2025 * mcheck.c: Don't include <stdlib.h>; just declare "void abort();"
2026 instead. This avoids portability headaches.
2027 * mips-tdep.c (mips_do_registers_info): Only print FP regs if
2029 * source.c (open_source_file): Avoid ANSI const bdeath by
2030 skipping declaration and then casting result value.
2031 * tm-hp300bsd.h: Clarify comment.
2032 * utils.c (strstr): Result is const char *; ANSI bdeath.
2033 * xm-hp300bsd.h: Define HOST_BYTE_ORDER. Redefine INT_MIN,
2034 since system include file defines it differently from "defs.h",
2035 though the two are equivalent for our purposes.
2036 * tconfig/hp300bsd: Add m68k-tdep.o.
2038 Tue Aug 20 16:01:11 1991 John Gilmore (gnu at cygint.cygnus.com)
2040 * tconfig/sun*4: Remove warnings about system assembler.
2042 Mon Aug 19 13:44:46 1991 John Gilmore (gnu at cygint.cygnus.com)
2044 * mcheck.c: Avoid warning about undeclared abort fn.
2045 * tm-sparc.h (PC_ADJUST): Avoid calling error() from this;
2046 it causes recursive calls to error() when used in cleanups.
2047 To do so requires that we make it a function, so we do.
2048 * sparc-tdep.c (sparc_pc_adjust): New implem of PC_ADJUST.
2049 * utils.c (do_cleanups): Remove the current cleanup from the
2050 chain *before* calling it, in case error() is called from it.
2051 The result won't be pretty, but won't be an infinite loop either.
2053 Mon Aug 19 00:41:04 1991 Michael Tiemann (tiemann at cygint.cygnus.com)
2055 * dbxread.c (read_struct_type): Grok anon structs for C++.
2056 (vb_name, vptr_name): Null terminate these strings.
2058 Fri Aug 16 08:31:03 1991 John Gilmore (gnu at cygint.cygnus.com)
2060 Minor bug fixes from BSD Net2 gdb:
2062 * blockframe.c (get_prev_frame_info): If FRAME_CHAIN_COMBINE
2063 returns 0, there is no previous frame.
2064 * breakpoint.c (commands_command): If !from_tty, don't call
2065 input_from_terminal_p().
2066 * dbxread.c (record_misc_function): Speed up slightly.
2067 (compare_psymbols): Ditto.
2068 * infcmd.c (do_registers_info): Take a second argument to
2069 determine whether to print float registers. "info registers"
2070 does not do so anymore. "info all-registers" does, now.
2071 * mips-tdep.c, pyr-tdep.c (xxx_do_registers_info): Take second
2073 * tm-mips.h, tm-pyr.h (DO_REGISTERS_INFO): Pass second arg.
2074 * inflow.c (initialize_inflow): Set tflags_ours correctly.
2078 * breakpoint.c (bpstat_do_actions): Use a cleanup to restore
2079 executing_breakpoint_commands if we are interrupted by error.
2080 * coffread.c (init_lineno): Avoid problem with zero-sized linetab
2081 versus malloc/free. From: john@labtam.labtam.oz.au (John Carey).
2082 * core.c (solib_add_stub, core_open): Call SOLIB_ADD inside a
2083 catch_errors() so we can setup the frame regardless of whether
2084 the shared libs work.
2085 * ieee-float.c (double_to_ieee_extended): Get exponent from
2086 right place in little-endian systems. From John Carey.
2088 Thu Aug 15 18:43:57 1991 John Gilmore (gnu at cygint.cygnus.com)
2090 * main.c: Remove unused terminating_signals and catch_termination().
2091 (long_options): Terminate with a zero element.
2092 [Bugfix from Atsuo Kawaguchi <atsuo@hark86.harl.hitachi.co.jp>.]
2093 (gdb_readline): Make call-compatible with readline.
2094 (init_signals): Improve comments re vfork vs. signal.
2096 * utils.c (prompt_for_continue): Use new gdb_readline().
2097 If we prompt for continuation, we don't let CR repeat the previous
2098 command, once we get back to a prompt. It's too easy to keep
2099 hitting CR, expecting "--more--" prompts, and have some long
2100 command start repeating on you.
2102 Tue Aug 13 16:17:56 1991 John Gilmore (gnu at cygint.cygnus.com)
2104 * blockframe.c (frameless_look_for_prologue): Speed up by
2105 calling SKIP_PROLOGUE_FRAMELESS_P if it's defined.
2106 * tm-sparc.h (SKIP_PROLOGUE, SKIP_PROLOGUE_FRAMELESS_P):
2107 Define two variants, one faster.
2108 * sparc-tdep.c (sparc_frame_chain): Use target_read_memory
2109 and return zero, rather than giving an error.
2110 (setup_arbitrary_frame): Initialize the PC in the new frame.
2111 (skip_prologue): Add a second arg saying whether we're just
2112 checking for a frameless function or not.
2114 * core.c (core_open, core_close, core_xfer_memory): Move
2115 section table pointers and bfd* into the target_ops.
2116 (core_open): Allow errors in shared lib reading, etc.
2117 (core_files_info): Describe shared library sections.
2119 * exec.c (exec_open, exec_close, exec_xfer_memory, xfer_memory,
2120 exec_files_info, set_section_command): Move section table
2121 pointers and bfd* into the target_ops.
2122 (add_to_section_table): Add BFD to section table.
2124 * target.c (target_xfer_memory, target_info): Pass target to
2125 xfer_memory and target_info functions.
2128 * gdbcore.h: Move struct section_table.
2129 * target.h: New home of struct section_table.
2131 * solib.c (solib_add): New argument is the target_ops whose
2132 section list is to be added to, if any. Reallocate the
2133 sections in that target to add any that come from shared libs.
2134 (throughout) so_sections renamed to sections.
2135 (solib_xfer_memory): Deleted.
2136 * tm-sunos.h (SOLIB_ADD): Add target argument.
2137 (SOLIB_XFER_MEMORY): Delete.
2139 * core.c, exec.c, inftarg.c, remote-eb.c, remote-nindy.c,
2140 remote-vx.c, remote.c, target.c, target.h: Remove add_syms vector
2141 from target_ops. It's the same on all targets. Add two section
2142 pointers to target_ops.
2144 * stack.c (find_relative_frame): Dump ancient algorithm for
2145 "down", just use handy "next" pointers.
2146 (frame_command): Don't error if there is no stack; let user
2149 * inflow.c (new_tty_prefork, new_tty): New prefork routine
2150 modifies static state in the parent process; new_tty itself
2151 runs in the child and modifies the child's file descriptors
2152 to match the saved static state.
2153 * infrun.c (child_create_inferior): Call new_tty_prefork,
2156 * infptrace.c (child_xfer_memory): Add ignored target arg.
2157 * remote-eb.c (eb_xfer_inferior_memory): ''
2158 * remote-nindy.c (nindy_xfer_inferior_memory): ''
2159 * remote-vx.c (vx_xfer_memory): ''
2160 * remote.c (remote_xfer_memory): ''. Rename from
2161 remote_xfer_inferior_memory.
2163 * main.c (main): Only try to attach "corefile" argument if
2164 it starts with a digit.
2166 * symfile.c (symbol_reloading): New "set/show" variable.
2167 (symbol_file_add): Shorten message about symbol reading.
2168 (add_symbol_file_command): Merge with add_syms_addr_command,
2169 since this should work on all targets now.
2170 (stop_whining): Default to zero, to shut up complaints
2171 about bad symbol tables on many systems.
2172 (free_named_symtabs): Just exit unless symbol_reloading.
2174 * xm-sun3os4.h, xm-sun4os4.h: Define BROKEN_LARGE_ALLOCA,
2175 and add comment explaining shared library screw.
2177 * source.c: #if defined => #ifdef.
2179 Thu Aug 8 12:23:19 1991 John Gilmore (gnu at cygint.cygnus.com)
2181 * doc/gdbint.texinfo: Improve doc on porting to new OS's.
2183 Tue Aug 6 17:16:15 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
2185 * doc/rdl-apps.texinfo: provide default readline-appendix finder
2186 (doc/Makefile knows how to make one for local config)
2188 * Makefile.in: use doc/Makefile for doc targets
2190 * doc/Makefile: GDB documentation now has its own Makefile
2191 doc/refcard.tex: renamed from "gdbrc.tex"
2192 doc/.Sanitize: add Makefile; recognize renamed refcard.tex
2193 doc/gdbint.texinfo: add markup in "Cleanups" chapter
2196 Fri Aug 2 00:13:06 1991 John Gilmore (gnu at cygint.cygnus.com)
2198 * values.c (baseclass_addr): When reading target memory, use the
2199 length of the basetype, not the upper type. We've only malloc'd
2200 enough space for the basetype, leading to errors in free().
2202 * expprint.c (print_subexp): Print UNOP_MEMVAL of an OP_LONG that
2203 ends up as a function specially, since we know the actual type of
2204 the pointed-to address. This (somewhat) fixes display of
2205 expressions that include misc_function_vector names. Try `cond 1
2206 !strcmp("a","b")' then `i b'.
2208 * infrun.c: Move DO_DEFERRED_STORES from proceed() to resume().
2209 The child can be proceeded from inside wait_for_inferior in
2210 evaluating breakpoint conditions, and DO_DEFERRED_STORES was
2211 getting skipped in that case.
2213 * expprint.c (print_subexp): Use filtered output, since the
2214 subroutines we call use it, otherwise the output is horribly
2215 mangled, since output of wrappable stuff comes out late.
2217 * Makefile.in: Bump VERSION to 3.98.1
2219 * infrun.c (child_create_process): Use execlp to find the
2220 shell to exec our target program. This requires some fiddling
2221 with `environ' since there is no execlpe().
2223 Thu Aug 1 15:35:17 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
2225 * Makefile.in, doc/gdbrc.tex, doc/rc-* (new files):
2226 Minor rearrangement of refcard permits two new make targets--
2227 gdbrc.dvi DVI output for refcard, using CM fonts
2228 gdbrc.ps PostScript refcard, using PS fonts
2230 Wed Jul 31 16:46:21 1991 John Gilmore (gnu at cygint.cygnus.com)
2234 * TODO, Projects, WHATS.NEW, README: Update for gdb-3.98.
2235 * Makefile.in (gdb-all.texinfo): Avoid touching file if M4 dies.
2237 Wed Jul 31 16:35:58 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
2239 * doc/gdb.texinfo: last changes for release.
2240 Minor typo and formatting fixes; incorporated most fixes remaining from
2241 filed mail commenting on earlier drafts.
2243 Added warnings: pipes don't work in run command;
2244 conditions are converse of assertions;
2245 step over fn without debug info goes to next fn;
2246 vars may have "wrong" values near fn entrance, exit
2248 Added example from Kingston on printing repeated nonadjacent values
2250 Added explicit mention that in Emacs gdb mode C-c and C-z are like
2251 shell mode for signals
2253 Renamed "Stepping and Continuing" to "Continuing and Stepping" so it
2254 doesn't sound so much like its parent "Stopping and Continuing"; also
2255 moved entries on continue to top of section, so they don't get lost.
2257 Improved installation directions in appendix, added manual formatting
2260 Tue Jul 30 17:26:39 1991 John Gilmore (gnu at cygint.cygnus.com)
2262 * configure.in: Remove xm.h and tm.h even if we aren't linking
2263 new ones, so "./configure sun4; ./configure none" does the right
2264 thing. Assume that alldeps.mak and depend are already built in
2265 srcdir, and avoid running "make" (particularly "make depend",
2266 which involves "gcc") from inside configure. Build Makefile
2267 directly rather than building Makefile.conf first.
2268 * configure: Regenerate with above changes.
2269 * Makefile.in: Use $(BISON) to find bison. Roll VERSION
2270 to 3.98. Revise gdb.tar.Z procedure to produce a file
2271 called gdb-$(VERSION).tar.Z but which unpacks into a
2272 directory called "gdb". Move non-source files out of
2273 $(SFILES_SUBDIR). Pretty up alldeps.mak with comments.
2274 (depend): Don't try to do "gcc expread.y".
2275 (expread.o): Update dependencies by hand.
2277 Mon Jul 29 15:21:09 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
2280 Fixed a variety of small typos that prevented info from formatting
2281 cleanly; altered too-long heading for GPL Appendix, as discussed
2282 w/RMS; Changed date on cover to July 91.
2284 Fri Jul 26 13:20:02 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
2287 (1) Applied some fixes due to comments from Larry Breed (easier ones
2288 through chapsec 5.2)
2289 (2) Eliminated use of @footnote---had my doubts about it anyways, and
2290 it's broken in latest texinfo
2291 (3) Introduced *some* use of [] for optional arguments, where
2292 explanation is not simpler by listing cmd w arg and cmd w/out arg
2293 separately. Still not using @deffn.
2294 (4) Dropped in GPL-2. NOTE: one of GPL-2 or texinfo is broken; a
2295 couple of headings are too long. Need patches to texinfo or revision
2298 * Partial update to README (which still needs work for this
2299 release!): (1) use of configure corrected for new script,
2300 (2) "make gdb.dvi" and "make gdb.info" mentioned.
2302 Wed Jul 24 06:44:02 1991 John Gilmore (gnu at cygint.cygnus.com)
2304 * symtab.c (lookup_symbol): Don't complain right off about
2305 no debug symbols; use the misc function vector first.
2306 (list_symbols): Use misc function vector to find symbols
2307 that don't have debug info, and print them.
2308 (find_pc_symtab): Temporarily avoid fatal() when psymtab
2309 PC range doesn't match symtab PC range, as it does on the
2310 MIPS because our symtab reading isn't perfect.
2312 * dbxread.c (dbx_symfile_read): Make warning about
2313 "no debug symbols" slightly nicer.
2315 * source.c (select_source_symtab): If "main" symbol exists,
2316 but decode_line_spec can't find line info, don't just return
2317 a zero; try other source symtabs or give an error.
2319 * mipsread.c (parse_partial_symbols): Sort the psymtabs by
2320 their low addresses first, then rip through fixing high addrs.
2322 * ns32k-opcode.h (sfsr): Bugfix from Rune Nerg}rd,
2323 <runene@ifi.uio.no>.
2324 (NS32K_SVC_IMMED_OPERANDS): Reverse the #ifndef.
2326 Tue Jul 23 18:52:43 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
2328 * Minor, mostly mechanical, cleanup of doc subdir for clean
2329 makeinfo'ing and TeXing; also ensured gdb-all.texinfo (post-m4)
2330 and gdb.info (post- texinfo2 makeinfo) generated for distribution.
2332 Sun Jul 21 03:54:52 1991 John Gilmore (gnu at cygint.cygnus.com)
2334 Mostly MIPS and general symbol-reading fixups.
2336 * doc/gdbint.texinfo: Add documentation on symbol-reading
2339 * mipsread.c: Remove kludges around #include "ecoff.h".
2340 Remove redefinitions of a_magic, etc, no longer used.
2341 (parse_symbol, ): Convert "Internal:" printfs to complain()ts.
2342 Fix global overview comments to match symfile.c protocol.
2343 (mipscoff_new_init): Eliminate cur_hdr if we have one.
2344 (mipscoff_symfile_read): Eliminate unused code. Avoid
2345 sorting all the symtabs, when all we have read here is psymtabs.
2346 The symtabs are sorted as they are created anyway. Tell
2347 condense_misc_bunches whether we're mainline.
2348 (psymtab_to_symtab_1): Pass filename when recursing, to make
2349 stack trace more informative.
2350 (parse_partial_symbols): Assume cur_hdr as argument.
2351 (read_mips_symtab): Don't clobber cur_hdr, so it can be freed.
2352 Pass cur_hdr implicitly to parse_partial_symbols. Avoid checking
2353 the TYPE_NAME of char *, since that's done in symfile.c.
2354 (free_numargs, parse_symbol, add_symbol, add_block,
2355 shrink_linetable): Declare these fns void.
2356 (upgrade_type): Convert tree of if's to switch. Clean up
2357 bogus "off == 0" handling with a complaint. Avoid setting
2358 field bitpos and bitsize of array with lower and upper bounds.
2359 Check specified bitsize of elements against their actual type's
2360 bitsize, and complain if different. Complain about unknown
2362 (parse_fdr): Don't assume sizeof(char *) == sizeof (struct *).
2363 (psymtab_to_symtab_1): Print names of subsidiary files that
2364 are being read in. FIXME, we read far too many files. This code
2365 is not the problem, the problem is in parse_fdr where the psymtabs
2367 (cross_ref): Result should indicate that we used one aux entry
2368 normally, or two if we encountered a "next" entry. This used
2369 to leave the caller pointing at the wrong aux entry.
2370 (add_symbol): If overflowed cur_block, reallocate it larger,
2371 chase all pointers to it, and complain(), rather than clobber memory.
2372 (shrink_block): Use xrealloc rather than xmalloc-and-copy.
2373 (new_field): Only allocate one field initially, not two.
2374 Pull ++ out of macro argument. Simplify.
2375 (_initialize_mipsread): Avoid initialization of importd
2376 global_psymbols and static_psymbols.
2378 * symfile.c (psymtab_to_symtab): Depend on XXX_psymtab_to_symtab
2379 to properly set pst->symtab; avoid searching for it.
2380 (symfile_fns): Improve comments, add a FIXME.
2381 * dbxread.c: Update comments to reflect symfile protocol.
2382 (read_ofile_symtab, end_symtab): Return the symtab.
2383 (psymtab_to_symtab_1): Set pst->symtab.
2385 * coffread.c (coff_symfile_read): tell condense_misc_bunches
2386 whether we're mainline.
2388 * symfile.h (sym_fns): Remove unused sym_discard member.
2389 * coffread.c, mipsread.c, dbxread.c: Remove XXX_symfile_discard.
2391 * mtrace.c (mtrace): Take effect if mallwatch is set, even if
2392 the environment variable is not.
2393 * infcmd.c (finish_command): Use filtered printfs.
2394 * cplus-dem.c: Add struct tags to a few unnamed structs.
2395 * valops.c (value_coerce_array): Improve comments.
2396 * valprint.c (type_print_varspec_suffix): Print array size only
2397 if greater than zero.
2398 * m88k-tdep.c: Shift some lines left by one space, that had
2399 apparently been trashed at some point.
2400 * TODO: More things to do, a few got done.
2402 Thu Jul 18 22:46:05 1991 John Gilmore (gnu at cygint.cygnus.com)
2404 * symtab.h (LOC_EXTERNAL): Eliminate in favor of LOC_STATIC.
2405 (ldsymoff, ldsymlen, globals_offset, statics_offset): Improve
2407 * dbxread.c (read_dbx_symtab): LOC_EXTERNAL -> LOC_STATIC.
2408 * expread.y, findvar.c, symmisc.c: Ditto.
2409 * printcmd.c (address_info): Update printed forms of LOC_
2410 symbols. Elim LOC_EXTERNAL.
2411 (print_frame_args): Keep track of param stack offsets before
2412 re-looking up to find the local register param is kept in.
2414 * mipsread.c: Use <symconst.h> and <sym.h> rather than <syms.h>.
2415 Further integration of mipsread into gdb. Eliminate unused
2416 routines, duplicate declarations. Handle static symbols in
2417 psymtabs as well as external symbols. When reading symtabs,
2418 insert symbols into the correct block (global, static, or a local
2420 (read_mips_symtab, parse_partial_symbols): Don't pass useless
2422 (mipscoff_symfile_read): Don't call select_source_symtab.
2423 (parse_symbol): Use SYMBOL_VALUE_ADDRESS where appropriate,
2424 rather than SYMBOL_VALUE.
2425 (parse_external): Comment clobbering of top_stack.
2426 (parse_partial_symbols): Update comments. Allocate and parse
2427 static symbols as well as external symbols. FIXME, enum values
2428 are not handled in this pass, but should be. Inline new_psymbol.
2429 Use SYMBOL_VALUE_ADDRESS.
2430 (psymtab_to_symtab_1): Read symbols into global static block
2431 by default (until enter some function's local block context).
2432 (sort_blocks): Clean up STATIC_BLOCK as well as GLOBAL_BLOCK.
2433 (destroy_all_symtabs, new_psymbol): Eliminate, unused.
2435 * source.c (select_source_symtab): Select a source symtab
2436 from either the symtabs or, failing that, the psymtabs.
2437 (list_command): Update error message.
2438 (forward_search_command, reverse_search_command): Use getc, not
2439 fgetc, for speed. FIXME, add comment about buffers that die if
2440 overrun by long line.
2442 * values.c (unpack_field_as_long, modify_field): Avoid shifting
2443 by an entire word, which is not portable, if we have a 32-bit
2444 field. (Code in dbxread.c already turns such bitfields, if
2445 aligned, into ordinary ints, but fixing this will help for other
2446 symbol formats and for future changes.)
2447 * core.c (core_open): Handle ANSI const brain death.
2448 * utils.c (vprintf): Fix varargs typo.
2450 Sun Jul 14 00:42:53 1991 John Gilmore (gnu at cygint.cygnus.com)
2452 * findvar.c (find_var_value): Handle &function better.
2453 * TODO: Document work needed on &fn and &array.
2454 * printcmd.c (print_address_symbolic): New arg is the prefix
2455 to print if a name is printed.
2456 (print_address_demangle): Honor "set print address" now.
2457 Use new arg above to improve spacing of output.
2458 * valprint.c (val_print): When printing function pointers,
2459 print symbolic form too.
2460 * breakpoint.c (breakpoint_1): Use new print_address_symbolic.
2462 Mon Jul 8 19:02:46 1991 John Gilmore (gnu at cygint.cygnus.com)
2464 * core.c (memory_error): Reword error msg to mislead less.
2466 * mips-pinsn.c (print_insn_arg 'd'): Print $ with reg name.
2468 * mipsread.c (read_mips_symtab, read_the_mips_symtab,
2469 parse_partial_symbols): Use newer BFD internals (external_filehdr
2470 and external_aouthdr), byte-swap the fields that we care about
2471 before using them, and make the file header data local to
2472 read_the_mips_symtab rather than global.
2474 Sat Jul 6 01:34:15 1991 John Gilmore (gnu at cygint.cygnus.com)
2476 * ns32k-opcode.h (movmw, movmd): Fix opcodes. Bug fix
2477 from Rune Nerg}rd <runene@ifi.uio.no> on 5 Jul 1991.
2479 * main.c (command_line_input): Flush stdout and stderr
2480 before every call to readline. This reportedly fixes a bug
2481 that comes up in Sys V running emacs-gdb and/or xxgdb,
2482 when stdin/out are pipes or sockets.
2484 Thu Jul 4 14:47:06 1991 John Gilmore (gnu at cygint.cygnus.com)
2486 * configure.in, Makefile.in: Avoid rebuilding "depend" as much.
2487 Avoid declaring Makefile dependencies, because GNU Make stupidly
2488 tries to update it if we do.
2490 * coffread.c: Revise for minor changes to bfd internal coff
2493 * configure: If -template= is given a relative path, make it
2494 absolute before recurring in subdirectories.
2496 * configure, configure.in, Makefile.in: Install "configure" script
2497 as replacement for config.gdb.
2498 * config.gdb, Makefile.dist, Makefile.sdir: Remove
2499 * README: Update for configure, mostly. FIXME.
2501 * Add dec3100 as equivalent to littlemips. Indicate in all host &
2502 target config files that they are for the host. When the lines
2503 get copied into the Makefile, this makes it more obvious what's
2506 Mon Jun 24 23:49:07 1991 John Gilmore (gnu at cygint.cygnus.com)
2508 * sparc-opcode.h (trap opcodes): Avoid leading spaces or
2509 tabs, which end up in the disassembler output inadvertently.
2511 Wed May 29 23:01:03 1991 John Gilmore (gnu at cygint.cygnus.com)
2513 Make it compile cleanly in an ANSI GCC2 environment.
2515 * blockframe.c: <stdio.h>
2516 * cplus-dem.c: free takes a void *, ifdef __STDC__
2517 * dbxread.c (read_huge_number): avoid gcc2 bug hoisting calc of
2519 * defs.h (alloca): Avoid doing anything if alloca already def'd.
2520 * stddef.h, stdlib.h: Remove these files.
2521 * symtab.c: Avoid declaring qsort, close.
2522 * symfile.c: Avoid declaring close.
2523 * utils.c (vprintf): Declare "ap" arg as proper va_alist.
2524 * sparc-tdep.c: Avoid including lots of Sun-host-specific files.
2526 Assorted other changes.
2527 * dbxread.c: include "libaout.h", not "liba.out.h".
2528 * printcmd.c (print_frame_args): Set recurse properly for
2529 indentation of struct and array parameters.
2530 * valops.c (value_cast): Allow cast to void.
2531 * infrun.c (resume): If NO_SINGLE_STEP, call machine dependent
2532 single_step() in a target-independent fashion.
2533 * sparc-tdep.c (single_step): Don't call ptrace ourselves, just
2534 set up to be ready to continue. This makes us target independent.
2535 * infptrace.c (child_resume): Remove call to single_step; now
2536 can single step a SPARC target of any kind.
2538 Wed May 22 18:18:24 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
2540 * Makefile.dist, doc/gdb.texinfo, doc/*-m4.texinfo: split up GDB
2541 docn into separate sections---basically chapters, plus two loose
2542 pieces that can be configured to go in different places. This
2543 allows GNU m4 to preprocess the manual without coredumping.
2545 * Makefile.dist: tell TeX where to find texinfo.
2547 Mon May 20 12:15:04 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
2549 * Makefile.dist, doc/gdb.texinfo: respectively create, and use,
2550 the new target "rdl-apps.texinfo" which captures the Makefile
2551 variable that records where to find the Readline libraries.
2553 Sun May 19 05:36:59 1991 John Gilmore (gnu at cygint.cygnus.com)
2555 * tahoe-pinsn.c: #include "tahoe-opcode.h", not "opcode.h".
2556 * tm-tahoe.h (FIX_CALL_DUMMY): Ignore more parameters.
2557 * defs.h (const, volatile): Only define if not already defined.
2558 * Makefile.dist (gdb.tar.Z): Create doc subdir w/out CVS/RCS crud.
2560 * README: Update for release 3.95.
2561 * config.gdb: Don't create readline dir in subdir builds.
2562 * main.c: Include with "..." form for non-system include files,
2563 so "gcc -MM" for "make depend" works.
2564 Include readline files with "...h" rather than <readline/...h>.
2565 * mipsread.c: Include "ecoff.h" rather than "intel-coff.h".
2567 * coffread.c: Undo minor damage done by Rich Pixley. Use
2568 different internal and external representations of COFF
2569 data structures. Use new BFD routines for swapping them in and
2571 * symfile.c (free_named_symtabs): Avoid freeing file names that
2572 are null or empty. Old i960 tools seem to produce files that
2573 claim to have empty names, causing each successive file read
2574 to blow away the previous one.
2575 * sparc-xdep.c (deferred_stores): Repair minor damage by Rich.
2576 Move deferred_stores to top of file, but don't separate its
2577 #define's from its variable. Add commentary.
2578 * Makefile.dist: Fix Rich damage; undo "configure" changes in
2579 favor of keeping the (working) config.gdb. Move readline
2582 Fri May 17 12:49:56 1991 Per Bothner (via gnu at cygint.cygnus.com)
2584 * dbxread.c (read_struct_type): Try to handle g++ version 1 MI
2586 * infptrace.c (fetch_registers): no result, since now void.
2587 * tconfig/news: target depends on m68k-tdep too.
2589 Fri May 17 14:40:14 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
2591 * Makefile.dist: added readline/inc-*.texinfo to dependencies for
2594 * readline/inc-history.texinfo, readline/inc-readline.texinfo:
2595 applied various small fixes due to or inspired by RMS comments
2597 * doc/gdb.texinfo: finished using all RMS comments, save those for
2598 appendices on readline and cmd history (which are in other source
2601 Thu May 16 18:06:05 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
2603 * doc/gdb.texinfo: (1) Updated w/ref to RMS comments through
2604 chapter 9; (2) documented 'break' command's menu mode for
2605 overloaded names, in response to hgs problem report C++ p-31
2607 Wed May 15 11:02:48 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
2609 * doc/gdb.texinfo: (1) better introductory example; (2) more
2610 consistent use of @code, @samp, @file, @kbd throughout; small
2611 cleanups to first three nodes; (3) new "Contributors" node;
2612 (4) Appendix, Renamed Commands; (5) divert specialized startup
2613 instructions to "Targets" chapter for generic manuals, while
2614 leaving them up front for manuals specific to specialized
2615 environments; (6) apply fixes from RMS comments through chapter 4.
2617 * pretex.m4: modify explanatory text slightly (and redefine
2618 "regexp") to keep GNU m4 from complaining. (It still crashes
2619 later, but one step at a time...)
2621 Wed May 15 10:32:12 1991 John Gilmore (gnu at cygint.cygnus.com)
2623 * readline/readline.c (update_line): Avoid dereferencing a pointer
2624 before comparing it to its bounds. Saber caught this.
2625 (init_terminal_io): Don't set BC from the "pc=" termcap variable,
2626 and only set PC if tgetstr returned non-null. Saber caught this.
2628 Tue May 14 16:29:53 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)
2630 * Makefile.dist: put gdb.dvi stuff (updated to use M4 preprocessor
2631 stuff for config manual) here where it counts; updated
2632 to use new subdir structure (gdb/doc/).
2634 * Makefile: generated from above via
2638 * gdbint.texinfo: added instructions on generating gdb.info* files
2639 locally for release. These are ordinary info
2640 files, formatted from gdb.texinfo (via gdb-all.texinfo, see
2641 Makefile)---but due to use of texinfo 2, can't count on makeinfo
2642 to generate these, so we distribute them already formatted.
2644 * gdb.texinfo: included full Info node and menu crud (as generated
2645 by C-u M-x texinfo-master-menu using the texinfo-2 elisp code).
2647 * Makefile: updated "gdb.dvi" target to use M4 preprocessor;
2648 put in comments-for-future gdb.info target (one day makeinfo will
2651 Tue May 14 13:51:36 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)
2653 * gdb.texinfo: Updated to include new or old undocumented
2654 commands, at least the following (perhaps some others I forgot to
2655 record): info f, info float, info path, info program, info s, info
2656 set, info source, info terminal, info types, info user, set/show
2658 Also covered all recent GDB command renames for v4.
2660 Mon May 13 14:57:46 1991 John Gilmore (gnu at cygint.cygnus.com)
2662 * mipsread.c: Rather than keeping count of how many symtabs
2663 and psymtabs we have, for sorting purposes, count them when
2664 we need to sort. This fixes bug in rereading of symbol tables.
2666 Fri May 10 15:43:33 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)
2668 * infcmd.c: renamed "info path" to "show paths"

2682 * coffread.c, exec.c, infptrace.c, inftarg.c, remote.c, solib.c,
2683 symtab.h, target.c, target.h: Lint.
2684 * core.c: setup and select frame after reading shared libs,
2685 else reading shared libs will clobber them. Lint.
2686 * utils.c (error): Force out any buffered wrap text.
2688 Fri May 3 22:01:56 1991 John Gilmore (gnu at cygint.cygnus.com)
2690 * remote.c: Remove decls of memory_insert_breakpoint
2691 and memory_remove_breakpoint, no longer used. (Suggestion of
2694 * Makefile.dist: use ${subdir} in paths of BFD and LIBIBERTY,
2695 to make it easier to interface to "configure"'d libraries.
2697 Fri May 3 13:10:01 PDT 1991 Roland Pesch (pesch at fowanton.cygnus.com)
2699 * valprint.c: introduce "set p", "set pr", "show p" and "show pr" as
2700 aliases for set/show print.

2756 * coffread.c [TDESC]: Move setting of debug_info from
2757 coff_symfile_read to find_linenos and make it work with BFD.
2759 * cplus-dem.c [__STDC__]: Make x{m,re}alloc return void*.
2761 * signame.c: Cast const char* to char* when assigning to sys_siglist.
2763 * utils.c (strsave): Make arg const char* not char*.
2765 * infrun.c (wait_for_inferior) [SHIFT_INSN_REGS]: Use

2786 Mips bringup and general cleanup
2788 * cplus-dem.c: Move CPLUS_MARKER define to after defs.h.
2789 * infptrace.c (PT_WRITE_D, PT_READ_D): Use correct values.
2790 (This still doesn't seem to make MIPS bkpts work.)
2791 * mipsread.c: Remove dup "Reading symbol data..." msg.
2792 (symbol_file_command, add_file_command): Remove, obsol.
2793 * printcmd.c (ptype_command): Say "an enum" rather than "a enum".
2794 Wrap output appropriately.
2795 * stack.c (locals_info, catch_info, args_info): Check
2796 selected_frame rather than target_has_stack or coredumping.
2797 * valprint.c (type_print_varspec_suffix): Wrap "ptype" output of
2798 enums appropriately.
2800 Wed May 1 14:10:22 1991 Jim Kingdon (kingdon at cygint.cygnus.com)
2802 * signame.c: Include defs.h and param.h.
2804 * cplus-dem.c: Include defs.h and param.h.
2805 Makefile.dist: Don't hack in the "param.h".
2806 param.h: Don't include defs.h.

2809 can have both ints and enum type_pieces in it.
2810 ({push,pop}_type_int): New functions.
2812 Tue Apr 30 13:18:58 1991 Jim Kingdon (kingdon at cygint.cygnus.com)

2824 symtab.c, cplus-dem.c, value.h, expread.y, valprint.c,
2825 copying.awk, solib.c, inflow.c, symmisc.c
2826 : Lint. Use read_memory not read_memory_integer on CORE_ADDR's.
2827 Use {value_as,unpack}_pointer (added to values.c)
2828 not {value_as,unpack}_long on CORE_ADDR's.
2829 Use longest_to_int (added to defs.h) instead of cast to int.
2830 Remove from_tty arg to mod_path.
2831 Put symfile_bfd in {coff,dbx}read.c not symfile.h.
2832 Use OP_NULL instead of 0 where dummy enum exp_opcode needed.

2875 * param-no-tm.h: Make BITS_BIG_ENDIAN defined to 0/1, not defined
2876 or not defined. Don't define it based on TARGET_BYTE_ORDER if

2879 values.c (modify_field, unpack_field_as_long):

2883 Fri Apr 26 12:02:06 1991 Jim Kingdon (kingdon at cygint.cygnus.com)
2885 * tm-sparc.h: Add comments about gcc version 2 and structure passing.
2887 * xconfig/i386v{,32}{,-g}: Add XM_CFLAGS=-Dgetpagesize()=4096.
2888 gmalloc.c: #if 0 out !HAVE_GETPAGESIZE code.
2890 * expread.y (abs_decl): Accept '&' and '&' abs_decl.

3305 (set_section_command): New command ("section xxx yyy" -- should
3306 be renamed to "set section xxx yyy" FIXME) which sets the

3320 * i386-pinsn.c: Move #includes to top, remove useless ones.
3321 * i386-tdep.c: Don't bother including <.../reg.h> since we

3338 current frame in the core file, if we have one.

3359 tconfig/symmetry, tconfig/vxworks960, tconfig/vxworks68,
3360 xconfig/hp300hpux, xconfig/symmetry: Change names to shorter
3363 * command.c (user_info_1, user_info): New command for listing
3364 the user-defined commands.
3366 Wed Apr 3 15:00:26 1991 John Gilmore (gnu at cygint.cygnus.com)
3368 * dbxread.c (really_free_pendings): Clear file_symbols
3369 and global_symbols after freeing them; otherwise, running
3370 this function twice (if it appears twice on the cleanup
3371 chain), we try to free things twice.
3373 * dbxread.c (read_dbx_symtab): Calculate end_of_text_addr
3374 based on text_addr (the address of text in core), not on addr (the
3375 offset between text in the .o file and in core). This change
3376 is from Peter Schauer.
3378 * main.c: Define ALL_CLEANUPS as a cast of zero.
3379 (return_to_top_level): Use it.
3380 (main): Do all cleanups after each command run as part
3381 of the gdb startup sequence. Also do all cleanups before
3382 entering the command loop, and every time we exit the command
3383 loop and reenter. Before, the cleanups from the startup sequence
3384 were being left undone until the first error!
3385 (command_loop): Rename do_nothing cleanup to command_loop_marker
3386 so we can see it easily when examining the cleanup chain.
3387 (init_signals): Add another do_nothing for signal handling.
3388 (quit_command): Only try to kill target if it has execution.
3389 Problems in the target stack got us into a state where
3390 inferior_pid was nonzero but none of the targets had execution.
3391 In this state you couldn't exit gdb.
3393 * dbxread.c: Two changes from Peter Schauer.
3394 (echo_command): Fflush output after an echo command.
3395 (show_history): Pass all args to cmd_show_list.
3397 * utils.c (init_malloc): Call mtrace to turn on tracing
3398 if the environment variable MALLOC_TRACE is set to a file name.
3399 * mtrace.c: Add source file which provides a log of every malloc,
3400 free, and realloc to a trace file.
3401 * mtrace.awk: Add source file which analyzes the trace file.
3402 * Makefile.dist (GNU_MALLOC, MALLOCSRC): Add mtrace.{c,o,awk}.
3403 (VERSION): Roll to 3.94.3.
3405 * breakpoint.c (breakpoint_1): Add a space to "i watch" output.
3406 (check_duplicates): Don't bother with watchpoints.
3407 (set_raw_breakpoint): Comment about danger of this routine.
3408 (watch_command): Parse and eval all args before calling
3411 * solib.c (find_solib): Avoid error in referencing memory to
3412 see if any more shared libraries have been added. This is
3413 particularly useful if the target has terminated. Bug reported
3416 Changes from Peter Schauer <pesrem@regent.e-technik.tu-muenchen.de>
3417 in bringing up 3.94.2 on the Sun-3.
3419 * Makefile.dist: Include CFLAGS in rule for cplus-dem.o.
3420 * breakpoint.c (enable_breakpoint): Check for valid watchpoint
3421 expression (in scope) before reenabling watchpoint.
3422 * signame.c (init_sigs): Add missing declaration of i, fix
3423 sys_siglist declaration.
3424 * source.c (list_command): Fixed range computation to use
3426 * stack.c (backtrace_command): Do not allow command if target has
3427 no stack, print informative error message.
3428 * target.c (target_command): Do not write into command line
3429 because this fails if the target command is used in a user defined
3430 command. [This change was enhanced by gnu to support any-
3431 unique-prefix matching on target names.]
3432 * valops.c (value_struct_elt): Avoid infinite loop on an
3433 erroneous attempt to print the member of function (try p main.p).
3435 Mon Apr 1 17:05:45 1991 John Gilmore (gnu at cygint.cygnus.com)
3437 * expread.y (name_no_typename): Avoid reduce/reduce errors
3438 caused by ambiguity in handling NAME_OR_INT and NAME_OR_UINT.
3439 Since the GDB parser really doesn't use name_no_typename in a
3440 name-only context, the parser can't tell the diff between
3441 names and numbers here. Avoid allowing a name_no_typename
3442 to be a NAME_OR_*INT to resolve the conflict.
3444 Sun Mar 31 20:12:07 1991 John Gilmore (gnu at cygint.cygnus.com)
3446 Bugfixes from Mark Fox (markf@wrs.com) (test=testField.c):
3448 * valprint.c (val_print_fields): bitfield printing didn't handle
3449 byte order. Indirect through a few more fns to cope.
3451 * values.c (modify_field): also cope with byte order.
3453 Sat Mar 23 10:02:21 1991 John Gilmore (gnu at cygint.cygnus.com)
3455 Cleanup for release 3.94.2:
3457 * Makefile.dist: Pull REMOTE_OBS. Fix saber includes for BFD
3458 include files. Roll version to 3.94.2.
3460 * coffread.c (init_stringtab): Read length into unsigned char
3461 array before swapping; don't assume 32-bit longs.
3463 * target.c (target_info): Don't bother with get_sym_file, just use
3464 the symfile global variable.
3465 * symtab.h, symfile.c (get_sym_file): Delete it.
3467 * dbxread.c (dbx_symfile_init): Don't depend on long == 4 bytes.
3468 (define_symbol): Set symbol line number to 0 if not gcc-compiled.
3469 (read_type): Replace one more error() with complain().
3471 * mipsread.c (parse_partial_symbols): Replace printf with complain.
3473 * i960-tdep.c: Fix copyright attribution.
3475 * config.gdb: Quote all backquotes in doublequotes. You can
3476 quote me on that. BSD 4.4 shell found this one.
3478 * infptrace.c (throughout): The third argument to ptrace is an
3481 * infrun.c (wait_for_inferior): When program has terminated, we
3482 have to call target_terminal_ours before we pop that target off
3483 the stack (e.g. before a call to target_kill or
3484 target_mourn_inferior). This fixes problem where a program
3485 terminates, then GDB stops for (tty output) and you have to type
3486 "fg" to the shell to resume it. FIXME: This code for what to
3487 do after termination really should be in normal_stop instead.
3489 * gdbcore.h (read_memory_check): Change declaration; it changed
3492 * terminal.h: Include <sgtty.h> before <sys/ioctl.h>, since in BSD
3493 4.4 prereleases, this avoids a bug in their sgtty compatability
3495 * remote.c: Use terminal.h rather than hand-rolling the same.
3497 * signame.c, signame.h (psignal): Arg is unsigned, not int.
3498 * utils.c (strsave, strstr): Fix arg types.
3499 * valprint.c (val_print): lint
3501 MIPS symbol table support from Per Bothner:
3503 * symfile.c (symtab_fns): Remove initializer table that needs to
3504 be hacked for each new symbol file format supported.
3505 (add_symtab_fns): New function, chains symbol table
3506 handlers into the global list.
3507 (symfile_init): Search this list.
3508 * symfile.h: Add next pointer, declare add_symtab_fns.
3509 * coffread.c (_initialize_coffread): Call add_symtab_fns.
3510 * dbxread.c (_initialize_dbxread): Call add_symtab_fns.
3512 * mipsread.c (psymtab_to_symtab_1): return void instead of (struct
3513 symbol *). Thus, we no longer need the hack to trash
3514 pst->filename. Good, since that hack confused code in symfile.c!
3516 (reorder_symtabs, destroy_all_symtabs): Removed static
3517 all_symtabs, which was used to qsort symtabs in reorder_symtabs.
3518 Instead, the latter now uses a temporary array (stack-allocated
3519 from an obstack, and then freed).
3521 (parse_symbol): Added a hack to fix up BLOCK_{START,END} if they
3522 haven't been set in the outermost stBlock of a procedure. This was
3523 a problem with f77 binaries on Ultrix 4.?.
3525 (new_symtab, new_symbol, new_type): Continue changing code to use
3526 obstacks more and otherwise conform to dbxread internal style.
3527 Made the free_code of symtabs be free_linetable (as in dbxread)
3528 instead of free_contents. This implies memory leaks when reading
3529 a new symbol table, until the conversion is finished. Did change
3530 (struct symbol) and (struct type) to be allocated on the
3531 symbol_obstack. Blocks and blockvectors are among the things
3534 * mipsread.c (parse_partial_symbols, parse_fdr): It hasn't been
3535 tested much, but it solved one problem (reported by Meissner), and
3536 cleans up some other things. The problem happened when an
3537 included file contains actual code (functions) and not just
3538 definitions. The mips coff is a little inconvenient there, since
3539 it may cause a procedure to be mapped to the wrong psymtab.
3541 * mips-tdep.c (heuristic_proc_desc): Minor cleanup.
3542 * mips-xdep.c (fetch_core_registers): Minor cleanup. FIXME,
3543 this will need work for the new core paradigm.
3545 Opcode patches from the net:
3547 * mips-opcode.h: fix incorrect disassembly of the mfc1, cfc1, and
3548 ctc1 instructions. Also, the cvt.d.w and cvt.s.w instructions were
3549 missing altogether - they are added here. From Bruce Bauman.
3550 * mips-opcode.h: The low mask for C0 instructions was too small.
3551 From Garrett Lau. I modified the fix to check the entire 32-bit
3554 * ns32k-opcode.h: Fix opcodes for deiw and deid. From Bruce
3557 Thu Mar 21 12:56:46 1991 John Gilmore (gnu at cygint.cygnus.com)
3559 Roll in changes from Per Bothner (Tue, 25 Sep 90 11:11:04):
3561 * dbxread.c (read_type): Pointer subtraction (value_sub in
3562 valarith.c) sometimes failed because the types of the
3563 pointers being subtracted were not identical.
3564 These differed because dbxread.c was allocating pointer types
3565 using dbx_alloc_type+smash_to_pointer_type instead of
3566 lookup_pointer_type. I failed to find a justification for the
3567 former, so I changed it to use the latter. Similarly, I
3568 replaced smash_to_function_type by lookup_function_type,
3569 and smash_to_reference_type by lookup_reference_type.
3571 * mipsread.c (parse_symbol, upgrade_type, parse_procedure,
3572 _initialize_mipsread): corresponding changes.
3574 * symtab.c (smash_to_{pointer,reference,function}_type): eliminate.
3576 * source.c (mod_path): Do tilde_expand on each component of the path,
3577 rather than on the (list of) paths as a whole.
3578 (print_source_lines): Set first_line_listed in addition to
3579 current_source_symtab and current_source_line. If the source was
3580 not findable, after a "dir" command to fix the problem,
3581 a "list" would get the wrong lines.
3583 While I was there... (gnu):
3585 * dbxread.c (read_type): Change error to complaint.
3587 Thu Mar 21 12:56:46 1991 John Gilmore (gnu at cygint.cygnus.com)
3589 First attempt at detailed understanding of symbol table memory alloc.
3591 * dbxread.c (dbx_symfile_read): Free our string table if we
3592 aren't the mainline. Free the "info" struct since we're done with
3594 (init_psymbol_list): Free any previously allocated psymbol lists.
3595 (): FIXME: Should realloc-down the psymbol lists when done reading
3596 the main symbol file?
3598 * symmisc.c (free_symtab): Free fullname field too.
3600 * xm-hp300hpux.h (USG): #undef then #define so Makefile can -D.
3601 (REGISTER_ADDR): Make result type unsigned int.
3603 * xconfig/{i386*,hp300hpux,altosgas,altos}: All config files that
3604 define REGEX must also define REGEX1 (its dependency).
3606 Tue Mar 19 21:28:57 1991 John Gilmore (gnu at cygint.cygnus.com)
3608 * tconfig/i960: No longer works, points you at vxworks960 or
3611 * xgdb.c, XGDB-README: Remove file. Users can get the much
3613 * Makefile.dist: Remove all trace of xgdb.
3615 * breakpoint.c (breakpoint_1): Pass demangle arg to
3616 print_address_symbolic.
3617 (clear_breakpoints): Remove unused function.
3618 (breakpoint_re_set_one): Guts of breakpoint_re_set.
3619 (breakpoint_re_set): Use catch_errors to do them all anyway.
3621 * gdb-int.texinfo (Host versus Target): Add section on what is
3622 a "host" feature versus what is a "target" feature.
3624 * infcmd.c (path_command, path_info): Handle the PATH variable
3625 (object search path) as conveniently as the source search path.
3626 * environ.c (set_in_environ): Set some vars in GDB's environment,
3627 in addition to the child's. PATH, G960BASE, G960BIN for starters.
3628 * source.c (mod_path): New function, from guts of
3629 directory_command, modifies a path. Used by path_command.
3630 (directory_command): Call it.
3631 * defs.h (strsave): Declare.
3633 * utils.c (sevenbit_strings): Add new printing option.
3634 (printchar): Use it.
3635 (strsave): Provide this handy helper routine.
3636 (set_width_command): Rename set_screen_width_command.
3637 (_initialize_utils): "set screen-width" => "set width";
3638 "set screen-height" => "set height"; add sevenbit-strings.
3640 * infcmd.c (do_registers_info): Print floating point registers
3641 in raw hex as well as float format, regardless of whether it is
3642 a "virtual" convertible register.
3643 * tm-sparc.h (PRINT_REGISTER_HOOK): Print every pair of float
3644 regs as a double, just in case it's being used that way.
3645 * values.c (unpack_long): Comment on array/function coercion.
3646 (unpack_double): Argument is in target byte order now. For
3647 integer arguments, just call unpack_long and float the result.
3648 * m68k-tdep.c: include defs.h for "const" handling.
3649 * remote-nindy.c: Use ieee-float stuff.
3650 (nindy_fetch_registers): Unpack double regs to host double, then
3652 (nindy_store_registers): Pack extendeds to host double, flip
3653 around by misusing unpack_double, send as target double.
3655 * tm-vxworks68.h (FRAME_CHAIN): Handle current frame pointer of
3656 zero, as when stopped at the first instruction of a process.
3658 * blockframe.c: Fix filename in comment (param.h => tm.h).
3659 * sparc-tdep.c (skip_prologue): More explicit nudging comments.
3660 * tm-68k.h: Fix typos.
3662 Fri Mar 15 01:09:34 1991 John Gilmore (gnu at cygint.cygnus.com)
3664 Changes from a bringup on the DEC Vax under Ultrix 4.0.
3666 * coredep.c (fetch_core_registers): Pass end-address of register
3667 section to register_addr as expected. Don't call supply_register
3668 if we'd just pass it garbage.
3670 * dbxread.c (read_dbx_symtab): Skip N_NSYMS on Ultrix.
3672 * exec.c (xfer_memory): Use boolean xfer_fn result, not int.
3674 * target.c (push_target, target_info): Cast enums to int for < or
3677 * stack.c (print_frame_info): Identify source file & line
3678 even if we can't print it.
3680 * xm-vax.h (MISSING_VPRINTF): No longer missing in Ultrix V4.0.
3682 Sat Mar 9 10:08:20 1991 John Gilmore (gnu at cygint.cygnus.com)
3684 Clean up IEEE floating point support.
3686 * ieee-float.h: New file.
3687 * ieee-float.c: Write real routines to convert between host
3688 doubles and various target IEEE extendeds.
3689 * m68k-xdep.c: Eliminate assembler code for extended floats.
3690 * xconfig/{3b1,altos,altosgas,hp300bsd,isi,news,news1000,sun2os3,
3691 sun2os4,sun3,sun3os3,sun3os4}: Eliminate use of m68k-xdep.o.
3692 * tm-i960.h, tm-68k.h (REGISTER_CONVERT_TO_VIRTUAL,
3693 REGISTER_CONVERT_TO_RAW): Use ieee_extended_to_double and
3694 double_to_ieee_extended.
3695 * i960-tdep.c: Define ext_format_i960.
3696 * m68k-tdep.c: Define ext_format_68881.
3697 * sparc-tdep.c: Define ext_format_sparc, though unused.
3698 * Makefile.dist (HFILES): Add ieee-float.h.
3699 * inftarg.c: #include "ieee-float.h" for the REGISTER_CONVERT
3702 Obsolete the "coffstrip" program in favor of using BFD's strip.
3704 * nindy-share/coffstrip.c: Remove file.
3705 * nindy-share/nindy.c (coffstrip): Routine to run bfd_strip.
3706 * Makefile.dist: Remove references to nindy-share/coffstrip.c.
3707 * tconfig/nindy960: Remove reference to coffstrip.o.
3709 * Makefile.dist: Roll version number to 3.94.1 (not yet final).
3711 Wed Mar 6 09:56:45 1991 John Gilmore (gnu at cygint.cygnus.com)
3713 * symfile.h: Add symfile_bfd, common between dbxread and coffread.
3714 * dbxread.c: Remove static symfile_bfd.
3715 * infcmd.c (do_registers_info): Add PRINT_REGISTER_HOOK, though
3717 * inftarg.c (child_detach): Pop the child_ops vector if the
3718 detach is successful.
3719 * remote-nindy.c (nindy_create_inferior): Don't push a new
3720 nindy_ops since nindy uses the same one for execution and memory
3722 * core.c (core_ops): Use child_attach and child_create_inferior
3723 rather than default attach and create_inferior functions.
3725 Handle floating point registers in core files.
3727 * sparc-xdep.c (fetch_core_registers): Rewrite for float support.
3728 * sun3-xdep.c (fetch_core_registers): Rewrite for float support.
3729 This version untested since BFD doesn't yet support sun3 core
3731 * hp300hpux-xdep.c: Rewrite fetch_core_registers to new calling
3732 conventions. Fix comments and style. This version has not
3733 been compiled yet, since we have no HP inhouse.
3734 * core.c (get_core_registers): Look for two sections, ".reg"
3735 and ".reg2", and pass both to fetch_core_registers sequentially.
3737 Revise directory path yet again.
3739 * source.c (forget_cached_source_info): Not static any more.
3740 (init_source_path): New default source path is "$cdir:$cwd".
3741 (dir_command): Handle variable arguments ($cdir, $cwd).
3742 (source_info): Print "Compilation directory" rather than
3743 "Originally compiled in" to remind people of $cdir.
3744 (openp): If the path contains $cwd, use current directory.
3745 (open_source_file): If compilation directory is known, replace
3746 first $cdir in path with the compilation directory.
3747 (print_source_lines): Even if we can't print the lines, set the
3748 current symtab and line for future commands like "info source" or
3749 "breakpoint". Also, error message now contains the file name,
3750 line number, and file access error message.
3751 (_initialize_source): Fix help text to describe changes.
3752 * main.c (cd_command): Forget cached source info when we chdir.
3753 * utils.c (strstr): Add simple implementation.
3755 Tue Mar 5 01:41:40 1991 John Gilmore (gnu at fowanton.cygnus.com)
3757 * coffread.c (read_one_sym, init_linetable, init_stringtab):
3758 Byte-swap COFF symbol tables if necessary when reading them in.
3759 Use complain() to replace error message in one spot. Needs
3760 corresponding change in bfd/coff-code.h to make some symbol
3761 swapping routines non-static.
3763 Mon Mar 4 00:53:40 1991 John Gilmore (gnu at cygint.cygnus.com)
3765 Merge changes from Eirik Fuller, for UTek.
3767 * defs.h (errno): Add declaration.
3768 * altos-xdep.c, arm-xdep.c, convex-xdep.c, gould-xdep.c,
3769 hp300hpux-xdep.c, infrun.c, inflow.c, infptrace.c, i386-tdep.c,
3770 i386-xdep.c, pyr-xdep.c, mips-xdep.c, remote-eb.c, remote-nindy.c,
3771 remote-vx.c, source.c, standalone.c, stuff.c, sun386-xdep.c,
3772 symmetry-tdep.c, symmetry-xdep.c, umax-xdep.c, utils.c: Eliminate
3773 declarations of errno.
3775 * remote-eb.c: Define B19200 and B38400 as EXTA and EXTB.
3777 * remote-vx.c: Include <sys/time.h> for UTek; Sun gets it via
3778 <rpc/rpc.h> and <rpc/types.h>.
3780 Sat Mar 2 15:47:55 1991 John Gilmore (gnu at cygint.cygnus.com)
3782 * i960-tdep.c (examine_prologue): Add new argument limit,
3783 which stops the scan at the end of the prologue, or at the PC.
3784 This fixes a problem where it walks down into the code for the
3785 user's statements if that code looks like function prologues.
3786 Mark Fox and I have been bouncing this code back and forth, making
3787 small changes to it. Callers changed to match.
3789 Tue Feb 26 01:47:07 1991 Cygnus John Gilmore (cygnus at yuba)
3791 Cleanup for gdb-3.94 release final:
3793 * Makefile.dist: Remove remote-vx.c, remote-nindy.c, and all
3794 the .c files from vx-share and nindy-share, from the various
3795 macros, since they are not found via ALLDEPFILES.
3796 (SFILES): Add tm-i960.h.
3797 (alldeps.mak rule): Break out ALLDEPFILES_MAINDIR and
3798 ALLDEPFILES_SUBDIR. List all the nindy and vxworks subdir files
3800 (TAGFILES_MAINDIR): Change ALLDEPFILES to ALLDEPFILES_MAINDIR.
3801 (gdb.tar.Z): Use ALLDEPFILES_SUBDIR as well as SFILES_SUBDIR.
3803 Mon Feb 25 16:02:35 1991 Cygnus John Gilmore (cygnus at oldman)
3805 * am29k-tdep.c: Add contribution line.
3806 (examine_prologue): Cache information about function prologues in
3807 the misc-function-vector to avoid lots of references over the
3808 serial line while examining instructions.
3810 * core.c (core_close): New function made from cleanup_core.
3812 * core.c, exec.c, inftarg.c, remote-eb.c, remote-nindy.c,
3813 remote-vx.c, remote.c, target.c, target.h,
3814 Update target_ops vector to add attach, close, and load entries.
3815 Use add_syms_addr_command, not add_file_addr_command, for
3816 add_file. Break out close routine from existing code.
3818 * dbxread.c (really_free_pendings): Don't free pending_blocks;
3819 they are in an obstack.
3820 (read_dbx_symtab): Relocate end_of_text_addr in the psymtab.
3822 (define_symbol): Add symbol type parameter; change callers;
3823 pass type parameter to DBX_PARM_SYMBOL_CLASS macro to allow
3824 it to influence the symbol class on the i960.
3825 (define_symbol): Swap LOC_CONST's into target byte order.
3827 * exec.c (exec_close): New function.
3828 (exec_file_command): Call it.
3830 * findvar.c (read_relative_register_raw_bytes): Doc byte order,
3831 Fix byte order of frame pointer.
3832 (read_var_value): Result of 0 if var's value can't be found,
3833 e.g. missing FRAME_ARGS_ADDRESS. Byte-swap LOC_CONST and
3834 LOC_LABEL values to target order. Add LOC_LOCAL_ARG.
3835 (locate_var_value): Use read_var_value and use its lazy address
3836 as the location of the var's value. Lint.
3838 * i960-pinsn.c (next_insn): Add routine from vxgdb for scanning
3841 * i960-tdep.c (arg_address, i960_frame_find_saved_regs): Remove
3842 obsolete Intel versions in favor of vxgdb versions.
3843 (check_host, byteswap, byteswap_val, reorder_val): Eliminate
3844 code dealing with byte order of values, which Intel did in host byte
3845 order rather than gdb-4's target byte order.
3846 (i960_frame_chain_valid): Move to nindy-tdep.c.
3847 (examine_prologue, skip_prologue, frame_find_saved_regs,
3848 frame_args_address, leafproc_return, saved_pc_after_call,
3849 pop_frame): Add vxgdb versions from Mark Fox.
3850 (examine_prologue, frame_struct_result_address): Add code
3851 to deal with the saved value of G13 (struct return address
3853 (frame_args_address): Modify Mark's version to prefer the
3854 saved value over the current value in the topmost frame.
3855 Cache result in the frame info to avoid performance hair in
3857 (print_fault): Add gdb960 code for printing faults.
3858 (_initialize_i960): Actually call check_host.
3860 * ieee-float.c (ieee_extended_to_double, ieee_double_to_extended):
3861 add stub routines. FIXME, these currently just return zero!
3863 * infcmd.c (program_info): Use PRINT_RANDOM_SIGNAL.
3864 (attach_command): Call target_attach, not target_open, now.
3866 * infrun.c (normal_stop): Make global, not static, for vx_attach.
3867 (child_attach): Rename from child_open.
3868 (wait_for_inferior): Use PRINT_RANDOM_SIGNAL. If stop_pc is zero,
3869 don't confuse it with a zero step_resume_break_address.
3871 * inftarg.c (child_detach): Eliminate inferior_pid test.
3872 (child_files_info): Clean up message a bit.
3873 (child_ops): Use child_attach, not child_open, to attach.
3875 * mem-break.c: #ifdef out the whole file if BREAKPOINT is not
3876 set (e.g. on VxWorks or NINDY). Move read_memory_nobpt from
3877 findvar.c to here, since it depends on the contents of the
3878 shadow_contents of breakpoints, but keep if #if 0 since it is
3881 * nindy-tdep.c: New file, contains nindy_frame_chain_valid, moved
3884 * printcmd.c (address_info): Handle LOC_LOCAL_ARG. Lint.
3885 (ptype_command, display_command): Eliminate have_inferior_p and
3886 have_core_file_p in favor of target_has_stack or
3887 target_has_execution.
3888 (print_frame_args): Handle LOC_LOCAL_ARG. Eliminate duplicate
3889 code for actually finding the values of arguments, though we still
3890 keep track of the maximum stack offset for use in printing unnamed
3891 arguments. Handle missing FRAME_ARGS_ADDRESS.
3893 * remote-nindy.c (i960_print_fault): Move to i960-tdep.c.
3894 (struct nindy_regs): Define registers passed to/from nindy.
3895 (nindy_fetch_registers, nindy_store-registers): Translate between
3896 nindy and GDB formats for the registers.
3897 (dcache_init): Statically allocate the cache, since it was being
3898 allocated by a malloc that was never freed anyway.
3899 (nindy_create_inferior): Error, not core dump, if no exec file.
3900 (nindy_before_main_loop): Use target_load, not target_add_file.
3902 * remote-vx.c (net_load): Specify large timeout for load
3903 requests. Allow user to break out with INTERRUPT.
3904 (net_break): Remove useless code, clean up. Change callers.
3905 (parse-args, skip_white_space, find_white_space): Clean up arg
3906 parsing to cope with quoted strings.
3907 (net_wait, net_quit): Never call error, just return status.
3908 (vx_read_register, vx_write_register): Cleanup status checking.
3909 #ifdef the code based on which CPU we are using (960 or 68k),
3910 FIXME, this should be completely general but it isn't yet.
3911 (vx_xfer_memory, vx_resume): Cleanup status checking.
3912 (vx_run_files_info): Improve message.
3913 (vx_load_command): Renamed from vx_add_file_command. Allow load
3915 (net_ptrace): Remove unused routine.
3916 (vx_wait): Adopt code from vxgdb960 to cope with broken
3917 connections to target machine and prompt to disconnect. Remove
3918 debug printouts. Map some EVENT_'s to SIGnals.
3919 (add_symbol_stub, vx_open): Print names of object files we found,
3920 and "ok" if we read their symbols OK. Clarify output in general.
3921 (vx_attach, vx_detach, vx_kill): Add these commands.
3922 (vx_convert_from_virtual, vx_convert_to_virtual): Simplify.
3923 (vx_run_ops): Turn off all_mem, to avoid spurious msg in the
3924 "info files" output, and create_inferior, since we already have
3927 * stack.c (frame_info): Replace Frame_unknown with 0.
3928 (print_frame_arg_vars): Handle LOC_LOCAL_ARG.
3929 (return_command): Pop until the PC matches as well as the FP,
3930 so it works even if the FP is shared with another function,
3931 as in "frameless" or "leaf" procedures.
3933 * symfile.c (load_command): renamed from add_file_target_command.
3934 (add_syms_addr_command): renamed from add_file_addr_command.
3935 (add_syms_command): Stub to call target_add_syms.
3936 (_initialize_symfile): Change command names and descriptions,
3937 add-file => add-syms, and load from alias to its own command.
3939 * target.c (kill_or_be_killed, maybe_kill_then_attach,
3940 maybe_kill_then_create_inferior): Default for attempts to start
3941 a process, if one is already running, is to ask about killing
3942 it and retry if yes.
3943 (upstack_create_inferior): #if-0 it, strata obsolete it.
3944 (push_target, unpush_target, pop_target): to_close() a target
3945 before unstacking it.
3946 (target_info): Renamed from target_files_info.
3947 (_initialize_targets): Rename "i files" as "i target", accessible
3950 * target.h: Improve comments about the target_ vectored routines.
3952 * tm-i960.h: Remove NINDY-specific stuff to tm-nindy960.h.
3953 Convert commenting style to standard GNU style.
3954 (DBX_PARM_SYMBOL_CLASS): allow LOC_LOCAL_ARG's to be recognized.
3955 (SKIP_PROLOGUE): No longer a no-op.
3956 (SAVED_PC_AFTER_CALL): Now handles leaf procedures.
3957 (*_REGNUM): Sort register numbers.
3958 (REGISTER_BYTES, REGISTER_BYTE, REGISTER_RAW_SIZE,
3959 MAX_REGISTER_RAW_SIZE, REGISTER_CONVERTIBLE,
3960 REGISTER_CONVERT_TO_VIRTUAL, REGISTER_CONVERT_TO_RAW): Float regs
3961 are now 10 byte extendeds, not 8 byte doubles.
3962 (FRAME_CHAIN_VALID): Make this config-dependent, since it differs
3963 for nindy versus vxworks targets. FIXME, this should possibly go
3964 in the target vector.
3965 (EXTRA_FRAME_INFO, INIT_EXTRA_FRAME_INFO): Cache both
3966 frame_saved_regs and arg pointer with each frame.
3967 (FRAMELESS_FUNCTION_INVOCATION): New leafproc support.
3968 (FRAME_ARGS_ADDRESS): Use cached result.
3969 (FRAME_ARGS_ADDRESS_CORRECT): New, avoids g14 guessing.
3970 (FRAME_FIND_SAVED_REGS): Change arg to subsidiary fn.
3971 (PRINT_RAMDON_SIGNAL): Call print_fault.
3972 (POP_FRAME): Now works.
3974 * tm-nindy960.h: Break this off tm-i960.h. NINDY-specific
3975 option parsing and startup; STACK_END_ADDR, FRAME_CHAIN_VALID,
3976 BREAKPOINT, and DECR_PC_AFTER_BREAK are here.
3977 (ADDITIONAL_OPTION_HANDLER): use target_load, not
3980 * tm-vxworks960.h: Break this off tm-i960.h. VxGDB specific
3981 startup; DECR_PC_AFTER_BREAK, and FRAME_CHAIN_VALID are here.
3983 * valarith.c (value_subscripted_rvalue): Avoid handling
3984 floats and doubles specially; it gave alignment errors. Lint.
3986 * valops.c (value_of_variable, value_of_this): Error if unknown
3989 * valprint.c (print_floating): Bcopy rather than pointer-deref,
3990 to avoid alignment problems.
3991 (value_print): Handle unknown value address.
3992 (cplus_val_print): Two args are ignored; remove them. Change caller.
3993 (val_print): Use unpack_long rather than pointer-deref.
3996 (unpack_long, unpack_double): Use bcopy rather than pointer-deref
3997 to avoid alignment problems.
3998 (value_being_returned): Error if return value unknown.
3999 (set_return_value): Add bogosity warning, FIXME. *
4001 * TODO: A woman's work is never done.
4003 * Makefile.dist: Distribute REMOTE_OBS into tconfig files.
4004 Separate INCLUDE_CFLAGS for use with lint. Add LINTFILES.
4005 Add ieee-float.o to OBS.
4006 * tconfig/{nindy960,vxworks68,vxworks960}: Include the desired
4007 REMOTE_OBS remote-interface files in the TDEPFILES and TM_FILE.
4008 * tconfig/i960: FIXME. Half-merge, produce warning if config'd.
4010 Changes to generalize the VxWorks RPC protocol slightly, to handle
4011 i960 as well as 68000.
4013 * vx-share/dbgRpcLib.h (VX_SOURCE_STEP): Add.
4014 * vx-share/reg.h: Produce i960 regs #ifdef I80960
4015 * vx-share/xdr_ptrace.c: Skip FPA registers if 960.
4016 * vx-share/xdr_rdb.h: Add SOURCE_STEP struct and xdr decl.
4017 * vx-share/xdr_rdb.c: Add xdr_SOURCE_STEP routine.
4018 * vx-share/xdr_regs.c: Add xdr_regs, xdr_fp_status, xdr_ext_fp
4019 for i960. Change xdr_vectors to xdr_opaques for 68k registers,
4020 so they will move in target byte order rather than network
4021 byte order (happens to be the same).
4023 Mon Feb 25 03:41:44 1991 John Gilmore (gnu at cygint.cygnus.com)
4025 * tm-convex.h (END_OF_TEXT_DEFAULT): Remove #if 0'd block.
4027 Sun Feb 24 00:55:53 1991 John Gilmore (gnu at cygint.cygnus.com)
4030 Add contribution lines to various files, showing where they
4033 * breakpoint.c (break_insn, check_break_insn_size,
4034 read_memory_nobpt): Remove to mem-break.c.
4036 * xm-*.h, param-no-tm.h, tm-29k.h, valprint.c: Change BYTE_ORDER to
4039 * tm-29k.h (STAB_REG_TO_REGNUM): Warn user if symbol table
4040 entry has bad register number. This change is not
4041 tested in this release, FIXME.
4043 * frame.h: Eliminate Frame_unknown in favor of a simple zero.
4046 * value.h: Force value's contents field to be aligned to hold
4047 at least a double or a long long (if supported). This avoids
4048 doing bcopy's in and out of the contents field.
4050 (step_1): Avoid coredump under obscure circumstances when we
4053 * symtab.h (misc_info): Add field to misc function vector for
4054 any kind of cached information the target code desires. AMD
4055 29000 uses this to avoid repeating examine_function_prologue's.
4057 * coffread.c: Lint. Remove static symfile, read_section_header.
4058 core.c (have_core_file_p): Lint: remove.
4059 expprint.c (print_subexp): Lint.
4060 infptrace.c, valops.c, valprint.c: lint.
4062 Roll in changes from vxgdb-5.0.1:
4064 * symtab.h: Comment byte order of each address class. Add
4065 LOC_LOCAL_ARG for frame-relative args (960).
4066 expread.y: Use LOC_LOCAL_ARG where LOC_ARG is used.
4067 symtab.c, symmisc.c: ditto.
4069 * infrun.c (init_wait_for_inferior): Clear stop_signal.
4071 * remote.c (remote_resume): Error if resume with a signal.
4073 * symfile.c (prim_record_misc_function): Clear misc_info.
4074 (fill_in_vptr_fieldno): Check stub type of arg.
4076 * valops.c (value_cast): Avoid looking up names of types whose
4077 name we don't know, to prevent coredump. Sun CC produces typedef
4078 rtx and the name of *rtx is zero...
4080 Mon Feb 18 21:16:25 1991 John Gilmore (gnu at cygint.cygnus.com)
4082 Roll in changes from final AMD 29000 port (Tiemann).
4084 tconfig/am29k: Add COFF_ENCAPSULATE and TARGET=TARGET_AM29K
4085 for ../include/a.out.encap.h. This might not work now that BFD
4086 is separately compiled. Instead, BFD support for encap will have
4087 to translate machine type 29k into the right COFF_MAGIC.
4089 * infcmd.c: Remove references to inferior_pid that aren't used
4090 in actual ptrace calls; use target_has_execution, etc.
4091 (have_inferior_p): Remove function.
4092 (program_info): Print target info rather than "process number";
4093 avoid gratuitous messages unless from_tty.
4094 (run_stack_dummy, finish_command): Set proceed_to_finish.
4095 infrun.c: Remove inferior_pid refs. Decl & init proceed_to_finish.
4096 main.c: Lint. Lose have_inferior_p().
4097 inferior.h (have_inferior_p): Remove, lint.
4098 (proceed_to_finish): Add flag to ask that all regs be saved
4099 by normal_stop, for the few commands that need it, speeding up
4100 serial I/O. Add comments to stop_registers.
4102 * remote-eb.c: Remove newline from breakpoint message we grep
4103 for. Never time out when running the user program.
4107 Wed Feb 13 15:34:40 1991 John Gilmore (gnu at cygint.cygnus.com)
4109 Roll in changes from vxgdb-5.0.1:
4111 * dbxread.c (read_dbx_symtab): If we encounter a "FORTRAN COMMON"
4112 symbol in its raw form, we are processing an unlinked ".o" file.
4113 See if the target environment has assigned it an address, using
4114 target_lookup_symbol (VxWorks does), and enter it into the symtab
4117 * tm-vxworks.h (FRAME_CHAIN, FRAME_CHAIN_VALID): Override usual
4118 68k versions for a simpler version that assumes zero FP at bottom.
4119 Fixes bug of truncated stack reports.
4121 * target.h (target_lookup_symbol): Define this routine's args
4122 and result, finally.
4124 * target.c (nosymbol): Default routine for target_lookup_symbol.
4125 (target_default): Default lookup_symbol and call_function too.
4126 (files_info): Only print has_all_memory warning if a non-dummy
4129 * remote-vx.c (vx_read_register, vx_convert_to_virtual,
4130 vx_convert_from_virtual): If target does not have floating point,
4131 zero register "values", and avoid doing cross-net conversions.
4132 (vx_lookup_symbol): Rename net_lookup_symbol, add to vectors.
4133 (vx_open): Rearrange code that attaches to target and reads
4134 symbols for all loaded modules, to work if some of the modules
4135 are not accessible. Add symbol_stub() and add_symbol_stub()
4136 as callbacks from catch_errors(). Allow connect attempt to be
4137 interrupted painlessly with ^C (FIXME, there are still some bugs
4138 if the interrupt happens during symbol reading.). Print
4139 final message with puts_filtered, since symbol messages are
4144 * main.c (catch_errors): Only print errstring if non-null.
4145 (command_loop): Avoid an ioctl per command to test ISATTY.
4147 * remote-vx.c (net_load): make static; avoid sophomoric msg.
4148 (vx_xfer_memory): Return correct result!
4149 (vx_files_info): Indicate whether target has float or not.
4150 (vx_lookup_symbol): Complain, not error, if target gone.
4151 (vx_open): Print "Connected" msg before disabling immediate-quit.
4152 [FIXME: lookup_symbol and vx_open changes need testing.]
4154 target.c, remote-eb.c, inftarg.c, am29k-opcode.h, target.h,
4155 tm-29k.h, tmm-vxworks68.h, symfile.c, gdb-int.texinfo: Add
4156 contributor lines and update copyrights to 1991.
4158 Changes from an attempted H-PUX host port:
4160 * infptrace.c (PT_ATTACH, PT_DETACH): Handle HP/UX, which
4161 defines PT_ATTACH and PT_DETACH but not PT_KILL.
4162 * remote-eb.c (eb_open): Misplaced endif kills sysv H/PUX.
4163 * remote-vx.c: include <sys/time.h> for HPUX.
4164 * hp300hpux-xdep.c (fetch_core_registers): Rewrite old
4165 "core_file_command" routine to BFD regime. May not work yet.
4167 Attempted port of "gdb-3.4 Van Jacobson xgdb" to modern gdb.
4169 * xgdb.c: Replace X10 version with some VJ version.
4170 (FIXME: Its copyright assignment is not on record.)
4171 * xgdb.c: Update include files to X11R4 (Xaw crud).
4172 (xgdb_display_source, create_text_widget): fix call to
4173 get_filename_and_charpos. Rewack source window stuff for X11R4
4174 (gleaned from include files, and "nm's" of binary libraries, since
4175 I had no doc available).
4176 (append_selection, append_selection_word): Disable with FIXME
4177 since R4 changed interface here.
4178 (create_buttons): Add back the old set of buttons.
4179 (xgdb_create_window): Fix call to XtInitialize (&argc not argc).
4181 * Makefile.dist (xgdb, xgdb-init.c): Update for X11R4 on Suns.
4182 Roll VERSION to 3.94 (not yet final though).
4184 Sat Feb 9 09:46:25 1991 John Gilmore (gnu at cygint.cygnus.com)
4186 * obstack.h (obstack_ptr_grow, obstack_ptr_grow_fast,
4187 obstack_int_grow, obstack_int_grow_fast): Eliminate
4188 cast on left of assignment, which gives MIPS cc fits and is
4191 * sparc-pinsn.c (print_insn): Eliminate 'set' test, subsumed by
4192 F_ALIAS. Use printf, not fprintf, when not passing a file
4194 (compare_opcodes): Check that identical instructions have
4195 identical opcodes, complain otherwise.
4197 * sparc-opcode.h (st %fsr): Fix opcode "lose" mask. This
4198 was reported by Roland McGrath.
4199 (unimp): Only match if exactly zero instruction. (Roland)
4200 (branches and traps): Generate all variations of these
4201 instructions with macros, based on a single call that defines
4202 each condition name and its binary representation.
4203 (set): Turn on alias bit, to avoid test in sparc-pinsn.c.
4205 * valprint.c (val_print_fields): Take, and use, format parameter.
4206 This means that "p/x struct" again prints the elements in the
4207 desired format. Changed callers.
4209 * stack.c (frame_info): Use filtered output, and indicate wrap
4210 points. Remove kludgy formatting designed to avoid line wrap.
4212 * utils.c (wrap_here): If the line is already full (because
4213 we had printed a long indent or long wrapped string), do an
4214 immediate newline-and-indent.
4216 * m68k-pinsn.c (print_insn_arg): Bugfix from
4217 ntmtv!thompson@ames.arc.nasa.gov (Mike Thompson): 'bkpt #0'
4218 instruction is incorrectly disassembled as bkpt #8.
4220 * dbxread.c (end_psymtab): Bugfix from Peter Schauer
4221 <pesrem@regent.e-technik.tu-muenchen.de>: If you want to set a
4222 breakpoint in a *.y file gdb will say Reading in symbols for *.y...
4223 and then will dump core (sometimes). I traced it back to an
4224 uninitialized symfile_name in psymtab_to_symtab.
4225 (const_vol_complaint): Add quotes to message.
4226 (define_symbol): Only believe line number if gcc_compiled.
4227 Avoid allocating symbol if we will not return it.
4229 Add target strata support so that newly established targets go
4230 into their right place in the target stack (e.g. a new exec file
4231 doesn't wipe out the ability to access the running process).
4233 * target.h, core.c, exec.c, inftarg.c, remote-eb.c,
4234 remote-nindy.c, remote-vx.c, remote.c, target.c: Add to_stratum
4235 and initialize it properly in all the targets.
4237 * target.h: Document strata. Change return type of push_target.
4239 * target.c (nomemory): new function for dummy memory access.
4240 (tcomplain): Rename complain, now also used in symfile.c.
4241 (push_target): Push targets within strata. New return value shows
4242 whether new target is on top of stack or not. Always keep dummy
4244 (target_files_info): Ignore dummy target.
4246 * core.c (core_open): Warn user, and skip accessing file, if the
4247 core target is not the topmost target in the stack.
4248 * remote-nindy.c (nindy_create_inferior): Avoid unpush_target, now
4251 * remote-vx.c: Remove vx_prepare_to_store from vxworks memory
4252 target_ops, it doesn't belong there since we have no regs there.
4253 Change name of target from machine => memory to clarify.
4255 Thu Feb 7 16:32:09 1991 John Gilmore (gnu at spiff.cygnus.com)
4257 * Freeze version 3.93 for release.
4259 * Makefile.dist: Handle vx-share and nindy-share subdirs
4260 properly when building gdb.tar.Z.
4262 * symtab.c: lint; add no_symtab_msg to consolidate the messages
4263 printed in various places, so I could change just one copy.
4265 * dbxread.c, coffread.c: Change references to bfd->iostream
4266 to cast to FILE *, now that BFD avoids needing types defined
4267 in other header files.
4269 Tue Feb 5 21:39:35 1991 John Gilmore (gnu at cygint.cygnus.com)
4271 * command.c, dbxread.c, expprint.c, infcmd.c, infptrace.c,
4272 infrun.c, printcmd.c, remote-nindy.c, source.c, sparc-tdep.c,
4273 sparc-xdep.c, symfile.h, symmisc.c, utils.c, valprint.c: Lint
4274 (actually gcc -Wall).
4276 * dbxread.c: Remove first_global_sym, last_global_sym, since
4277 they are never referenced.
4279 * defs.h (baud_rate): Declare.
4280 main.c: Define it, and add the -b option to set it.
4282 * gdb-int.texinfo: Add text on how to define a new host or target
4283 architecture, prompted by Per Bothner's questions about MIPS
4286 * gdb.texinfo: Document "complaints". Change doc of -q since
4287 gdb no longer prints the copyright and blurb if you specify a file
4288 name to be debugged (just like Emacs). Add doc for Nindy-specific
4289 command line flags for specifying target serial port and such.
4290 Update copyright to 1991.
4292 * gdbcore.h: Remove a large mass of now-useless crud, since BFD
4293 has taken over for us the job of ripping up executable files. The
4294 crud caused Per Bothner's port to not compile.
4296 * infrun.c (normal_stop): Avoid printing "Program exited
4297 normally" if we are in batch mode. This allows a GDB which
4298 executes a program on a target system, to behave like a Unix
4299 command (input from stdin, output to stdout, no extraneous
4302 * main.c (main): Allow additional machine-dependent command line
4303 options to be specified with the ADDITIONAL_OPTIONS,
4304 ADDITIONAL_OPTION_CASES, ADDITIONAL_OPTION_HELP, and
4305 ADDITIONAL_OPTION_HANDLER macros. Also allow machine-dependent
4306 processing to occur just before the main loop with
4307 BEFORE_MAIN_LOOP_HOOK.
4308 (main): If a "core file" argument is specified, and it is not a
4309 core file, try it as a process ID to attach.
4310 (symbol_completion_function): Attempt to cope with
4311 "show screen-" TAB, not very successfully. This needs more work,
4313 (batch_file): New function, returns whether we are reading
4314 commands from an interactive tty on stdin, or from somewhere else.
4315 Called by normal_stop since it doesn't get from_tty passed down
4316 to it like many commands do.
4318 * remote-nindy.c: Handle command line options for nindy
4320 (nindy_before_main_loop): Prompt user for tty name if they
4321 don't specify it before getting to the interactive command loop.
4323 * tm-i960.c: Add ADDITIONAL_OPTIONS, etc, to handle -O, -brk,
4324 and -r command line options. Also add hook before main loop
4325 to make it easy to specify a tty.
4327 * TODO: More things to do, one done.
4329 Mon Feb 4 23:57:39 1991 John Gilmore and Mike Tiemann (at cygint.cygnus.com)
4331 * dbxread.c: Make complaint() calls pass pointer, not struct.
4332 Add complaints about badly formatted C++ type information
4333 (const/volatile indicator, and parse errors resulting in
4334 error_type). Fix C++ virtual member fn comment.
4335 (read_struct_type): Avoid bumping pointer if we got a parse
4336 error; this prevents our walking beyond the end of a string.
4337 Terminate loop on null char as well as semicolon.
4338 (process_one_symbol): Fix the LBRAC fix so that it uses the
4339 last previous SLINE, FUN, or SO record's PC address. C++ debug
4340 symbols did not have SLINE records in a useful order compared
4341 to the LBRAC records.
4342 (define_symbol): Handle "catch" records.
4344 * symtab.c (check_stub_type): Added new complain
4345 `stub_noname_complain' and added a consistency check to
4346 keep the debugger from crashing when finishing from an
4347 exception frame. A real fix will be needed later.
4349 Sat Feb 2 10:43:05 1991 John Gilmore (gnu at cygint.cygnus.com)
4351 * infcmd.c (attach_command): Make global.
4353 * Makefile.dist (REMOTE_OBS): Make these compile by default,
4354 but make them easy to comment out. Perhaps later they should
4355 be enabled by what CPU you configure for? FIXME.
4356 (VERSION): Roll to 3.93.
4357 (pinsn.o): Remove rule for obsolete file.
4358 (dbxread.o,coffread.o,mipsread.o): Use ${srcdir} explicitly.
4360 Run down a problem that manifested by printing the wrong function
4361 name in stack traces of read_ofile_symtab. Turned out that the
4362 problem was the SunOS 4.1.1 (and previous) C compiler outputs
4363 the LBRAC symbol with an address in the *data* segment, which
4364 blew our binary search through the blocks.
4366 * dbxread.c: Use the complain() facility consistently to bitch
4367 about problems in the symbol file we are reading.
4368 (finish_block): Add code to check the nesting of the blocks;
4369 complain and Procrust them to fit if wrong.
4370 (make_blockvector): Check the order of the blocks, complain
4371 [but don't cope] if wrong.
4372 (process_one_symbol): ifndef SUN_FIXED_LBRAC_BUG, check LBRAC
4373 symbols to be sure their PC value is greater than the last SLINE
4374 (line number) symbol we've seen, complaining and adopting the
4375 SLINE PC value if wrong.
4377 * symfile.h (struct complaint, complaint_root, complain,
4378 clear_complaints): Add.
4379 * symfile.c (complain, complaint_root, clear_complaints): Add
4380 facility to deal with non-fatal complaints and to regularize their
4382 (symbol_file_add): Clear complaint counters to allow new complaints.
4383 (initialize_symfile): Add 'set complaints' and 'show complaints'.
4385 * dbxread.c (dbx_symfile_read): Remember the address and size
4386 of the string table for the main symbol file, so we won't read it
4388 (dbx_psymtab_to_symtab): Fix the check for main symbol file,
4389 to avoid reading the string table yet again. Lint.
4390 (throughout): Improve filtered output, including word wrap.
4391 (read_range_type): Improve Bothner's fix to handle other types too.
4393 * utils.c: Improve line wrap implementation. Handle unlimited
4394 width by making chars_per_line unsigned.
4395 (puts_filtered): New, easy, function.
4397 * defs.h (puts_filtered): add.
4399 * mipsread.c (compare_symbols, sort_symtab): Remove these fns,
4400 call the identical sort_symtab_syms() in symfile.c instead.
4402 * expread.y: Suggest the `file' command rather than `symbol-file'.
4404 * command.h (enum var_types): Add zinteger for seroable
4406 * command.c (do_setshow_command): Handle var_zinteger. Restructure
4407 nested if's into a switch.
4409 * breakpoint.c (bpstat_print): If bpstat "print" flag is not set,
4410 we did not stop because of a breakpoint (it must have been for
4411 some other reason, like a "stepi"), so don't print anything.
4413 * symtab.c: Include <sys/types.h> all the time. Now that BFD
4414 doesn't include <sys/types.h>, old SunOS's require it for
4417 Sat Feb 2 10:39:15 1991 Per Bothner (bothner@cs.wisc.edu)
4419 A test port of gdb-3.92.6 to the Sony NEWS.
4422 Don't normally link in remote- or vx stuff.
4423 Some of it doesn't compile, and it wastes space for 99% of the users.
4424 Remove reference to no-longer-used HAVE_VPRINTF.
4425 Fixed BFD_DEP typo to BFD_DIR.
4427 Fix cast in arg to bfd_h_getlong.
4428 Make char *prefix be const.
4429 Fix how certain range types are mapped into builtin unsigned int types.
4431 Remove 2 #includes. They cause errors (on Sony, at least),
4432 and aren't needed (they wern't in earlier versions).
4434 print_address_symbolic should never demangle labels
4435 (since it prints *assembler-level* labels).
4437 [This was superseded by the change to printcmd below.]
4440 Add some "volatile" return types to avoid warnings.
4441 If MISSING_VPRINTF add vprintf function and not just macro
4442 (since vprintf is used in printcmd.c).
4444 Unless __GNUC__, use obstack_grow instead of obstack_ptr_grow.
4445 (The latter isn't grokked by some PCC-based compilers.)
4447 [This change is in abeyance, we prefer to fix obstack_ptr_grow.]
4449 Make chunk size of dont_print_obstack 32*4 instead of default 4096.
4450 * nindy-share/coffstrip.c
4451 Added some forward declarations (otherwise, gcc complains
4452 about implicit extern redefined as static).
4454 Sun Jan 20 02:38:19 1991 John Gilmore (gnu at cygint.cygnus.com)
4456 Changes inspired by Per Bothner:
4457 * printcmd.c (print_address_symbolic): Take additional parameter
4458 specifying whether to demangle.
4459 (print_address): Pass in asm_demangle to control demangling.
4460 (print_address_demangle): New fn, takes explicit arg to control
4462 * utils.c: Add new vars demangle and asm_demangle, and let them
4464 (fputs_demangled): If !demangle, just print the argument.
4465 (fprint_symbol): If !demangle, just print raw symbol.
4466 * valprint.c (val_print): Call print_address_demangle rather than
4467 print_address, to cause demangling to depend on the global
4468 rather than assembler-level demangling setting.
4469 * WHATS.NEW, gdb.texinfo: Document.
4471 * main.c (show_command): Show all settings if no arg.
4472 (initialize_main): Make "info set" the same as naked "show".
4473 * command.c (cmd_show_list): Handle prefix commands in the
4474 list, and print the name of the setting as well as its English
4475 description and value.
4477 Allow gdb functions to specify where a line should wrap if it
4478 exceeds the size of a terminal line. Use it to make the output
4480 * utils.c (set_screen_width_command): New fn, mallocs a buffer
4481 of the right size when screen width changes.
4482 (set_screensize_command, screensize_info): Remove #if 0'd fns.
4483 (wrap_here): New fn, indicates a point in the output where we
4484 should wrap the line rather than just letting it overflow at a
4486 (fputs_filtered): Implement wrapping.
4487 (n_spaces): New fn, returns a pointer to N spaces.
4488 (print_spaces_filtered): Use n_spaces.
4489 * defs.h (n_spaces): Declare.
4490 * stack.c (print_frame_info): Wrap with 4-space indent after
4491 fn name and before filename and line number.
4492 * printcmd.c (print_frame_args): Wrap with 4-space indent
4493 before each argument name is printed.
4494 * valprint.c (value_print): Wrap with no indentation before
4496 (val_print_fields): Wrap with indentation relative to nesting
4497 level before each field name.
4498 (val_print): Wrap with nesting indentation before array elements.
4499 * command.c (do_setshow_command): Avoid extra newlines,
4500 wrap with 4-space indent around values printed, end with period.
4501 * WHATS.NEW, gdb.texinfo, gdb-int.texinfo: Document.
4503 * breakpoint.c (breakpoint_1): Implement addressprint for
4504 "info breakpoints" display. Change file name and line number
4505 format to " at file:nnn" rather than " (file line nnn)".
4506 * gdb.texinfo: Document.
4509 Fri Jan 18 07:21:25 1991 John Gilmore (gnu at cygint.cygnus.com)
4511 Frozen for gdb-3.92.6 release.
4513 README, WHATS.NEW: Update for 3.92.6 release.
4515 tconfig/{altos, i386v, i386v32, m88k, umax}: Eliminate
4516 coffread.o from configs since it is now built by default.
4517 tconfig/{3b1, altosgas, arm, convex, hp300bsd, hp300hpux,
4518 i386v-g, i386v32-g, isi, merlin, news, news1000, np1, pn,
4519 pyramid, symmetry, vax, vxworks68}: Eliminate dbxread.o
4520 from configs since it is now built by default.
4522 Makefile.dist: Update for release 3.92.6. Handle files that
4523 have been moved to ../include, ../getopt, or ../bfd. Add
4524 saber.suppress and tests directory. Add config.status to
4525 the release (it will say "none").
4527 coredep.c: Minor formatting fixes.
4529 These changes were made in early December but only checked in now:
4530 * nindy-share/Onindy.c, nindy-share/coffstrip.c,
4531 nindy-share/nindy.c: lint
4532 * nindy-share/nindy.c (ninStopWhy): Don't byteswap the
4533 register values coming back from the target; we store values
4534 in target byte order everywhere.
4536 Wed Jan 16 19:01:37 1991 John Gilmore (gnu at cygint.cygnus.com)
4538 * am29k-opcode.h, am29k-pinsn.c: Add 29050 opcodes.
4540 * valprint.c (cplus_val_print, val_print_fields): New functions,
4541 which print C++ objects. They conspire to avoid printing a
4542 virtual base class more than once, following all the twists and
4543 turns of C++ virtual base rules.
4544 (val_print): Call the above rather than do it by hand.
4546 * symfile.c (symbol_file_add): Only reset symfile_mtime for main
4547 symbol file, not for added files like shared libs. This really
4548 needs to be generalized to a timestamp per file.
4550 * core.c (cleanup_core): Avoid coredump if no core file.
4552 * config.gdb: Accept -host or -target in place of +host or
4555 * coffread.c (find_linenos): Avoid desupported BFD interface
4556 to line numbers. We still read them manually rather than using
4557 BFD's "generic" features.
4559 * gdbrc.tex, threecol.tex: Add GDB reference card and its
4561 Makefile.dist: Add refcard to OTHERS list for creating tar files.
4563 * Makefile.dist: Eliminate use of $< in explicit targets.
4565 * readline/Makefile: Use $< rather than $*.c, which does not
4566 include the VPATH in GNU Make.
4568 * tconfig/i960-bout, tconfig/i960-coff: These are identical
4569 copies of tconfig/i960, added for global configuration
4570 compatability. All i960 versions can read both coff and b.out.
4572 * tm-88k.h: Fix multiline macro that lacked \'s. Remove
4573 COFF_FORMAT and COFF_CHECK_X_ZEROES since these are now handled
4576 * TODO: Think of more things to do.
4578 Wed Jan 2 19:09:29 1991 John Gilmore (gnu at spiff.cygnus.com)
4580 tconfig/{am29k,i960,sun2*,sun3*,sun4*}: Eliminate config
4581 of sdb versus dbx debug symbols. Add kludge for 68881 80-bit to
4582 64-bit float conversion.
4584 tconfig/sun4, tconfig/sun3, xconfig/sun4, xconfig/sun3: Make
4585 equivalent to sun?os4 so global config works.
4587 Wed Jan 2 18:20:51 1991 John Gilmore (gnu at spiff.cygnus.com)
4589 Fix from Eberhard Mattes <mattes@azu.informatik.uni-stuttgart.de>
4591 * main.c: Only declare linesize once; declare pagesize not at
4592 all, since it is never used.
4593 (main): Clear newly allocated line before it is used.
4595 Fri Dec 28 00:13:42 1990 John Gilmore (gnu at cygint)
4597 Further stabilization for the Intel 960.
4599 * Makefile.dist: Parameterize the location of the "include"
4600 and "bfd" directories, as well as "getopt". Add symfile.c.
4601 Link in both dbxread and coffread. Fix up "make depend" to
4602 rewack the locations of include, bfd, and getopt in its output.
4604 * README: Document moving include files, improve some of
4607 * coffread.c: Move common code out to symfile.c. Change
4608 symbol_file_command style interface to use new *_symfile_init
4609 and *_symfile_read interface under BFD. Use BFD internal
4610 info to locate line table, symbols, etc.
4612 * core.c (core_fetch_registers): Rename to get_core_registers
4613 to avoid confusion with fetch_core_registers.
4614 (register_addr): Move to coredep.c, which is already machine
4615 dependent. This leaves core.c pretty clean of dependencies.
4617 * coredep.c (register_addr): Accept this routine from core.c.
4619 * dbxread.c: Move common code (with coffread.c, etc) into new
4620 symfile.c. Each psymtab now contains a pointer to the
4621 format-dependent function that knows how to read it in. Make
4623 (dbx_psymtab_to_symtab): Renamed from psymtab_to_symtab_2.
4624 (process_one_symbol): Add code to complain about a "compiler bug
4625 we muzzle here", if we actually see it.
4627 * eval.c (evaluate_subexp): Insert missing "break" statements
4628 in code that determines whether a variable is an lvalue in
4629 memory, register, or whatever. I detected this via a compiler
4630 bug in which it *almost* mashed out the whole switch statement.
4632 * gdb-int.texinfo: Add minor sections on configuring gdb for
4633 release, and about the README file.
4635 * infcmd.c (registers_info): Fix formatting somewhat. Still
4636 not as pretty as before, but it handles byte swapping.
4638 * remote-nindy.c: If data cache routines are interrupted while
4639 waiting for the remote end, be sure that any uninitialized cache
4640 blocks are on the free list, not on the valid list!
4642 * symfile.h: Flesh out this header file with all the various
4643 routines and variables that have been merged in from dbxread.c
4644 coffread.c, and symtab.c to symfile.c.
4646 * symfile.c: New file, containing code common to dbxread.c,
4647 coffread.c, and some code from symtab.c. All generic code for
4648 reading symbol files should be in here now.
4649 (unrecord_misc_function): Remove unused function.
4651 * symtab.h: Remove file-reading things to symfile.h.
4653 * symtab.c: Remove file-reading things to symfile.c.
4655 * tm-i960.h: Fix FRAME_CHAIN types; define PRINT_RANDOM_SIGNAL
4656 to decode i960 fault types.
4658 * target.h, remote.c, remote-eb.c, remote-vx.c, remote-nindy.c,
4659 target.c: Change type of the "resume" function from int to void,
4660 since its result was never used.
4662 Sat Dec 22 02:51:40 1990 John Gilmore (gnu at cygint)
4664 * main.c: Replace "stupid" with "caution"; you now "set caution
4667 * printcmd.c (print_scalar_formatted): Fix typo in 'g' format
4669 * infcmd.c (do_registers_info): Call val_print to deal with the
4670 byte order of the registers being printed. FIXME, this makes
4671 the formatting of the output uglier.
4673 * infcmd.c (wait_for_inferior): If PRINT_RANDOM_SIGNAL is
4674 defined, call it for signals the debugger doesn't itself use.
4675 The i960 uses this for more detailed fault information.
4677 * remote.c (remote_open): If arg is null, print help rather than
4680 * sparc-xdep.c (register_valid): Avoid declaring size, since
4681 various modules will think of various sizes depending on the
4682 architecture of their tm-file. FIXME, we need protection against
4683 actually entering one of those modules, which would clobber
4684 storage if not for the target architecture compiled into gdb.
4686 * stack.c (up_command, down_command): Always print the frame
4688 (up_silently_command, down_silently_command): New commands
4691 * i960-pinsn.c (reg), i960-tdep.c: Lint.
4693 * i960-tdep.c (i960_frame_chain_valid): Lookup_symbol now takes
4694 more parameters than it used to.
4696 * findvar.c (registers): Increase slop to 256 bytes, which should
4697 protect us against even most RISC machines with large register
4699 (locate_var_value): Move declaration inside related ifdef.
4701 * remote-nindy.c (): Use TIOCSETN rather than TIOCSETP
4702 throughout, to avoid throwing away buffered input from the board.
4703 (nindy_wait): Supply_register takes addr_of_value, not value.
4704 (i960_print_fault): Renamed from i80960_fault.
4705 (nindy_fetch_registers): Avoid have_regs stuff, just get them.
4706 (nindy_store_registers): Avoid regs_changed stuff, just stuff
4708 (nindy_create_inferior): Don't bother to write PC_REGNUM since
4709 we can set the PC in the call to proceed(). Unpush nindy_ops
4710 before pushing it on top, to avoid message to user. Eliminate
4711 commentary from Unix machines that just misleads here.
4712 (reset_command): Fix error message to suggest target command.
4714 Wed Dec 19 11:03:56 1990 John Gilmore (gnu at cygint)
4716 Release 3.92.5 as frozen.
4718 Stabilize the merged release...with help from lint, Saber C,
4721 Everywhere: Add include files needed to declare return types
4722 of functions called.
4724 * gdb.texinfo: Roland Pesch is documenting gdb, glory be!
4726 * breakpoint.h: Add undeclared breakpoint functions, and some
4727 functions for display handling since I couldn't think of a better
4730 * breakpoint.c (insert_breakpoints): Make code for disabling
4731 shared library bkpts more likely to work. It's used when we
4732 rerun a program and stop before the shared library has been
4734 (breakpoint_cond_eval, bpstat_stop_status): Pass arg as int,
4735 cast from pointer, so it squeezes through catch_errors.
4736 (bpstat_stop_status): Fix logic broken some time ago. We now
4737 always create a bpstat if the stop address matches a breakpoint,
4738 even if we don't stop there -- just like the old code used to do
4739 before I got my fingers into it (sigh).
4740 (breakpoint_1): Print "ignore count" after "stop only if"
4741 condition, since that's how it actually works.
4742 (mention): Handle watchpoints as well as breakpoints.
4743 (watch_command): use set_raw_breakpoint and mention to do most
4744 of the work (and initialize all the fields!). Only pass one
4745 arg to parse_c_expression, since that's all it takes.
4747 * command.c (not_just_help_class_command): Rename arg to args
4748 since we ignore "unused argument" warnings on vars named "args".
4749 inflow.c (child_terminal_info): ditto.
4750 infptrace.c (kill_inferior): ditto
4751 main.c (catch_errors, version_info, quit_command, pwd_command,
4752 source_command, dump_me_command, editing_info,
4753 set_history_size_command, set_history, show_history,
4755 stack.c (locals_info): ditto
4756 target.c (target_files_info): ditto
4757 valprint.c (set_input_radix, set_output_radix): ditto
4759 * core.c: Remove old variables for handling core and exec file
4760 sections (data_start, data_end, stack_start, stack_end,
4761 reg_stack_start, reg_stack_end, reg_stack_offset, text_start,
4762 text_end, exec_data_start, exec_data_end, text_offset,
4763 exec_data_offset, data_offset, stack_offset). They're
4764 superseded the more general build_section_table and
4766 (get_exec_file): Mention the `file' command.
4767 (read_memory_check): Rename to memory_error, and only call it
4768 in the case of an actual error.
4769 (read_memory, write_memory): call memory_error.
4770 (core_fetch_registers): Register section name is ".reg".
4772 coredep.c: Remove a bunch of crud now that all this file does
4773 is pull the registers out of a core file.
4774 (fetch_core_registers): Rewrite to actually work, I hope.
4776 dbxread.c: Use a.out.gnu.h, not system a.out, now.
4777 Replace index() with strchr(). Remove all the pre-BFD macro
4778 definitions for accessing the symbol file.
4779 (struct dbx_symfile_info): Encapsulate the information that
4780 dbx_symfile_init needs to pass to dbx_symfile_read in this
4783 (dbx_new_init, dbx_symfile_init, dbx_symfile_read,
4784 dbx_symfile_discard): Rearrange symbol file reading to divide
4785 the format-specific part from the format-independent part,
4786 leaving the format-independent part such as file name expansion
4787 and opening in symtab.c. This replaces
4788 partial_symbol_file_open and partial_symbol_file_read.
4789 Symbol_file_read, add_file, add_file_target_command,
4790 add_file_addr_command move to symtab.c. Pass an explicit
4791 "mainline" flag for when reading the main symbol table, rather
4792 than relying on the offset address to be zero or nonzero.
4794 (dbx_symfile_read): Don't allow void *'s to be printed as
4796 (SWAP_SYMBOL): Use bfd routines to byte-swap the symbols.
4797 (ADD_PSYMBOL_TO_LIST): Make the "function call rather than
4798 macro" debug version really work.
4799 (read_dbx_symtab): Remove unref'd parameter inclink.
4800 Avoid swapping N_SLINE symbols, for speed.
4801 Merge N_TEXT!N_EXT case with the other external symbol
4802 definitions' case. Add comments.
4803 (start_psymtab): Allocate the symfile name in the psymtab on
4804 the psymbol_obstack, rather than using the caller's storage.
4805 (end_psymtab): Only allocate a dependencies list if there are
4807 (psymtab_to_symtab_2): Use BFD when reopening file to read
4808 its symbols for real.
4809 (read_struct_type): Add FIXME comments where it needs work
4811 (read_huge_number): Add FIXME about overflows.
4812 (read_range_type): Add FIXME about comparing a long to 1<<32.
4814 * coffread.c: Minor changes to move things closer to the new
4815 regime with symtab.c and dbxread.c Major work is still needed
4818 * exec.c (exec_file_command): Remove old variables (see core.c
4820 (xfer_memory): If memory transfer is right at the end of a
4821 section, don't lose.
4823 * findvar.c (get_saved_register): If value is in a real
4824 register, LVAL is lval_register, not lval_memory.
4826 frame.h: Declare print_sel_frame and record_selected_frame.
4828 gdb-int.texinfo: New file, for GDB internals documentation.
4829 Very simple, unformatted doc of cleanups is there for now.
4831 gdbcore.h: Remove obsolete variables that described a.out
4832 section addresses and offsets. (See core.c above.)
4833 Declare fetch_core_registers and registers_fetched.
4835 getopt.c: Declare char *alloca(); even on SPARC.
4837 infcmd.c (run_command): Call target_kill rather than
4839 (step_command, next_command, stepi_command, nexti_command):
4840 Declare from_tty parameter even though we don't use it.
4841 (run_stack_dummy): argument BUFFER is a char array, not
4842 a pointer to REGISTER_TYPE.
4843 (finish_command): using_struct_return needed a value *,
4844 not a struct symbol *.
4846 * infptrace.c (child_xfer_memory): To avoid dependency on
4847 where sections are in memory, try PT_WRITE_D and if that fails,
4848 try PT_WRITE_I. Most Unixes don't care which you use.
4850 * infrun.c (step_resume_break_shadow): Change to array to
4851 match other breakpoint shadow storage.
4852 (clear_proceed_status): Pass address of bpstat to
4853 bpstat_clear, not the bpstat itself.
4854 (child_create_inferior): FIXME comment about if the child
4856 (start_inferior): Remove old function.
4857 (child_open): Use target_kill rather than kill_inferior.
4858 (wait_for_inferior): Ditto.
4859 (insert_step_breakpoint, remote_step_breakpoint): Use
4860 new step_resume_break_shadow.
4862 * inftarg.c (child_wait): If all child processes die,
4863 pretend that the one being waited for exited with signal 42.
4865 * main.c (command_line_input): When scanning for comments,
4866 don't coredump on unclosed quotes.
4867 (quit_command): Use target_kill rther than kill_inferior.
4868 (_initialize_main): Rename class_user from "user" to
4871 * printcmd.c (print_command_1): Initialize "fmt" if no format
4872 is specified by the user.
4873 (print_frame_args): Only add to args_printed if we are
4874 actually fetching args from the stack (avoiding undefined
4876 (_initialize_printcmd): Remove bogus \{ from string.
4878 * remote-eb.c (eb_open): Avoid coredump on no argument.
4880 * remote-nindy.c: Bring out of Intel environment into new
4881 target environment. Remove all conditional compilation on
4882 I80960. Massive hacking throughout.
4883 (nindy_xfer_inferior_memory): New routine stolen from
4885 (nindy_create_inferior): New routine pieced together, probably
4886 not quite working yet.
4887 (nindy_ops): New target_ops struct for nindy.
4889 * remote-vx.c: Use write_memory rather than target_write_memory
4890 to get error checking.
4891 (vx_add_file_command, vx_open): Use symbol_file_add rather than
4893 (vx_create_inferior): Use target_terminal_ours...
4895 * signame.c (_initialize_signame): Always initialize, since
4896 we need the table for things other than psignal.
4898 * solib.c (solib_add): Use symbol_file_add, not add_file.
4899 (solib_address): Return boolean result rather than struct
4900 pointer which nobody else knows the type of.
4902 * sparc-tdep.c, valops.c: Use write_memory rather than
4903 target_write_memory, to get error checking.
4905 * stack.c (locals_info, catch_info, args_info,
4906 get_selected_block, frame_command, up_command): Use
4907 target_has_stack, rather than have_inferior_p or
4910 * sun3-xdep.c (fetch_core_registers): Rewrite for new BFD regime.
4912 * symfile.h: New file, defining the interface between the
4913 generic and object-file-specific symbol reading code.
4915 * symtab.c: Move generic symbol-reading interface to symtab.c,
4916 from dbxread.c, coffread.c, mipsread.c, etc. Add symtab_fns
4917 table to map BFD targets to symbol-reading modules in GDB.
4918 Change index to strchr.
4919 (lookup_struct_elt_type): Use error() rather than hand-made
4920 simulations thereof.
4921 (lookup_partial_symbol): Speedup slightly when length == 0.
4922 (symbol_file_add): New function.
4923 (symbol_file_command): Call it.
4924 (symfile_open, symfile_init): New function.
4925 (add_file_target_command, add_file_addr_command): moved from
4928 * target.c (target_command): use target_kill.
4930 * target.h (target_files_info): Don't declare, never called
4933 * tm-sun2.h, tm-sun3.h (STACK_END_ADDR): Use system include
4934 files to determine stack end address.
4936 * valarith.c (value_x_binop, value_x_unop): Change error message
4937 to be more useful. Pass proper argument to value_struct_elt.
4939 * valops.c (value_assign): FIXME comment that long long
4940 bitfields will break here.
4942 * Makefile.dist: Add symfile.h, remote-nindy.c, remote-eb.c.
4943 Update `make saber_gdb' to work better.
4945 * TODO: A woman's work is never done.
4947 * cplus-dem.c, environ.c, inferior.h, infrun.c, inftarg.c,
4948 main.c, obstack.c, printcmd.c, remote-eb.c, remote-nindy.c,
4949 remote-vx.c, remote.c, solib.c, source.c, sparc-pinsn.c,
4950 sparc-tdep.c, sparc-xdep.c, symmisc.c, symtab.c, symtab.h
4951 target.c, terminal.h, tm-sparc.h, tm-sunos.h, utils.c,
4952 valops.c, valprint.c, exec.c: Lint.
4955 Wed Dec 12 23:44:15 1990 John Gilmore (gnu at cygnus.com)
4957 Continuing Intel 960 port merge of GDB.
4959 * Makefile.dist: Merge i960 "nindy-share" files. Rename
4960 malloc.h to gmalloc.h to avoid name conflicts in /usr/include.
4961 Don't ship gdb.dvi in tar file. Link gdb with init.o, not init.c.
4962 Wack over "make depend" so it handles files in subdirectories
4963 vx-share, nindy-share, bfd, and in the current directory.
4965 * blockframe.c (get_prev_frame_info): Remove fatal error
4966 if stack not defined.
4968 * core.c (core_open, core_detach): New functions that handle
4969 the old "core-file" command as "target core" and "detach" instead.
4970 (core_file_command): Call them.
4971 (core_xfer_memory): Use common routine xfer_memory.
4973 * dbxread.c: Include a.out.gnu.h, not system a.out.h.
4974 dbxread now uses bfd for everything but symbol reading itself.
4975 BFD internals are used to drag out the relevant file offsets.
4976 (partial_symbol_file_open): Change args all around for BFD.
4978 * symtab.c: Rename "value" to "val" everywhere, so we can
4980 (symbol_file_command): New command, moved from dbxread.c
4981 and coffread.c. It uses BFD to read the file, then vectors
4982 based on its type, to dbx or coff symbol readers.
4983 * symtab.h: Extern a few vars for symbol_file_command.
4985 * target.h: Breakpoint takes a char * save area, not a char **.
4987 * valprint.c (val_print): When unpacking bitfields, offset
4988 the address in gdb of the value, if it is declared with a shorter
4989 type. Remove the last "runtime kludge test" of host byte order.
4991 * utils.c: Remove old my_bfd_read routine.
4993 * stack.c (frame_info): Use target_has_stack. Print program counter
4994 register's actual name rather than "pc", since it's called the
4995 "ip" (instruction pointer) on the i960 (sigh).
4997 * target.c (target_command): Add command for selecting a target
4998 type and calling its open routine. This is used for initiating
4999 communication with a particular target, in a generic way.
5001 * tm-i960.h: Update for modern gdb. Remove semicolons from
5002 various macros. Handle reading struct return convention, and
5003 error-out attempts to return structs with the "return" command.
5004 Be sure gdb doesn't think we know how to call functions in the
5007 * i960-tdep.c: Rename FRAME_CHAIN_VALID and FRAME_FIND_SAVED_REGS
5008 to i960_xxx in lower case.
5009 (arg_address): Circumvent errors due to LOC_ARG_BLOCK
5010 not being defined yet.
5012 * remote.c (remote_open): Call start_remote to initialize
5013 wait_for_inferior during open.
5014 (remote_xfer_inferior_memory): Return length written rather
5017 * remote-vx.c (target_command -> vx_open): Use new generic
5019 * remote-eb.c, inftarg.c, exec.c: ditto.
5021 * infrun.c: Fix comments.
5022 (attach_program -> child_open): Use new generic target command.
5023 (wait_for_inferior): Clear saved register values before target_wait,
5024 so target_wait can set some of them if convenient.
5026 * infptrace.c (fetch_inferior_registers, store_inferior_registers):
5027 Return success indicator, not void.
5028 (child_xfer_memory): Avoid fetching initial word if we'll
5029 overwrite it anyway.
5031 * infcmd.c (attach_command): Use new generic target open routine.
5032 (_initialize_infcmd): Update doc on attach and detach commands.
5033 (do_registers_info): Merge in a byte-order problem as a FIXME
5036 * findvar.c (find_saved_register): Avoid problem in current frame.
5037 (read_relative_register): Ditto.
5038 (write_register): Convert byte order on the way out.
5040 * exec.c (file_command): Add.
5041 (add_to_section_table, exec_command): Use new bfd_map_over_sections.
5042 (xfer_memory): Common function between core_xfer_memory and
5044 (exec_xfer_memory): Use it.
5046 * pn-opcode.h: Document that a "PN" is a Gould PowerNode.
5048 * breakpoint.c, breakpoint.h, symtab.h, value.h, frame.h, utils.c,
5049 valops.c, stack.c, target.c, sparc-xdep.c, source.c, printcmd.c,
5050 infcmd.c, i960-pinsn.c, eval.c, defs.h: lint and gcc -Wall.
5052 Sun Dec 2 16:45:06 1990 John Gilmore (gnu at cygnus.com)
5054 Merge Intel 960 port of gdb, continuing...
5056 * dbxread.c (partial_symbol_file_open, partial_symbol_file_read,
5057 symbol_file_command): Pass from_tty arg to hush 'em up.
5059 * coffread.c (symbol_file_command): Avoid output if from_tty != 1.
5060 Add magic numbers for 960 COFF format.
5062 Fri Nov 30 09:18:20 1990 John Gilmore (gnu at cygnus.com)
5064 Merge Intel 960 port of gdb, from Intel "1.2" release.
5066 CHANGE_LOG entries from their port, which was based on
5069 Thu Sep 6 11:02:22 PDT 1990
5070 Remove temp file if download is interrupted.
5072 Wed Aug 1 09:08:33 PDT 1990
5073 Now uses binary protocol to talk to NINDY.
5074 Old hex protocol (NINDY 2.13 and older) supported with -O switch.
5075 Times out after 5 seconds when trying to talk to NINDY.
5077 Tue May 29 12:54:49 PDT 1990
5078 Added variable baud rate (-b switch).
5079 Source code reorganization.
5081 Thu Apr 26 11:09:55 PDT 1990
5082 More cleanup of batch mode; specifically, execute "-s", "-e", and
5083 "-se" switches as soon as they are encountered on the invocation line.
5085 Fri Apr 20 13:47:15 PDT 1990
5088 Thu Apr 19 09:54:28 PDT 1990
5089 Add 'reset' command.
5091 Wed Apr 18 09:48:07 PDT 1990
5092 After opening remote tty, wait for 1 second to go by without input
5093 from it before trying to talk to NINDY (fixes problems with the
5094 Heurikon HK80/V960E).
5096 Mon Apr 4 16:33:05 PDT 1990
5097 Some output was not being suppressed in 'batch' mode.
5099 Thu Mar 22 15:31:11 PST 1990
5100 Ask user if old symbol table should be deleted when new file is
5103 Allow user to run a program downloaded before gdb960 was brought up.
5105 Correct "exec-file" help message for i80960 context.
5107 Correct bug in calculating user space address: could occasionally
5108 corrupt user program.
5110 Make sure to zero low-order bits in rip's because of bug in 960CA
5111 A-step part: could cause operation faults when "next"ing across
5114 Correct bug that made it impossible to get source line numbers for
5115 code loaded at addresses higher than 0x7fffffff.
5117 Wed Jan 10 12:43:22 PST 1990
5118 Open remote tty for exclusive use.
5120 Fri Jan 5 12:14:42 PST 1990
5121 Correct disassembly (CA manual was right after all):
5122 opcode for sysctl is 0x659
5124 Mon Oct 23 12:03:04 PDT 1989
5125 Use G960BASE and G960BIN environment variables to find 'sx' utility.
5127 Mon Oct 16 14:15:09 PDT 1989
5128 "sfr0"-"sfr31" should have been named "sf0"-"sf31"
5130 Mon Oct 2 15:56:31 PDT 1989
5132 Added 960CA disassembly support.
5134 To simplify maintenance:
5135 - eliminated use of symblic links on pinsn.c: use i960-pinsn.c
5137 - eliminated opcode.h: incorporates tables into i960-pinsn.c
5138 - moved 960-specific routines from i960-pinsn.c to i960-md.c
5139 - made disassembly interface identical to that in gdmp960.
5143 Wed Nov 28 21:32:48 1990 John Gilmore (gnu at cygint)
5145 * target.h: Allow targets to stack. Add target_has_memory,
5146 _registers, etc. Restructure memory access and "info files"
5147 to walk the target stack.
5148 * exec.c, core.c, inftarg.c, remote.c, remote-vx.c, remote-eb.c,
5149 target.c: Change tables to match target.h.
5150 * inflow.c (child_mourn_inferior): pop child_ops.
5151 (generic_mourn_inferior): Use new has_stack flag.
5152 * infptrace.c (child_xfer_memory): New memory regime.
5153 * inftarg.c (child_files_info): New "info files" regime.
5154 * remote-eb.c: New memory regime, new info files.
5155 * remote-vx.c: New memory regime, new info files. Now use
5156 separate targets for VxWorks attachment to machine, and
5157 actually running a process under VxWorks, since one has
5158 stack & execution & regs and the other doesn't.
5159 * remote.c: New memory regime, new info files.
5160 * sparc-xdep.c (fetch_core-registers): New memory regime.
5161 * target.c: New routines and support for stacked targets,
5162 new memory regime, new info files regime.
5165 Generalize section handling for an arbitrary number of sections,
5166 including use of the new BFD (binary file) library.
5167 * gdbcore.h: Add struct section_table.
5168 * exec.c (build_section_table): Iterate all sections and
5169 record what gdb needs to know about them.
5170 (exec_command): Use it.
5171 (exec_xfer_memory): Use the table.
5172 (exec_files_info): Print the table.
5173 * core.c (core_file_command, core_xfer_memory, core_files_info):
5175 * source.c (find_source_lines): Use bfd_get_mtime.
5176 * dbxread.c: Quick changes to make it compile with new BFD.
5177 * utils.c (error): Avoid using bfd_error in generic routines.
5179 * core.c (core_fetch_registers): Get from the ".regs" section of
5181 * sparc-xdep.c (fetch_core_registers): Use the .regs info.
5183 * inferior.h (attach_flag): Export.
5184 * infcmd.c (run_command): use new target_create_inferior.
5185 * infrun.c (child_create_inferior): Don't return result.
5186 * Makefile.dist (VERSION): 3.91.4.
5188 Fri Nov 23 28:15:38 1990 John Gilmore (gnu at cygint)
5190 * breakpoint.c (bpstat_num): Handle breakpoints which have
5191 since been deleted, such as temporary breakpoints.
5192 infcmd.c (program_info): ditto.
5194 * core.c (core_file_command): Display the frame where the core
5199 * remote-vx.c (target_command): Merge in target command from
5200 targ-vx.c. A few other cleanups.
5202 * TODO, Projects: Lots more stuff to do...
5204 Fri Nov 23 18:15:38 1990 John Gilmore (gnu at cygint)
5206 Massive changes to wall off the remote-debugging interface
5207 behind a function vector. The port to handle VxWorks targets
5208 is also part of this.
5210 All files: Replace references to renamed functions,
5211 remove references to remote_debugging, remove references to
5212 have_include_file, have_core_file in favor of target_has_stack,
5213 target_has_memory, etc.
5215 * Modularize the breakpoint interface.
5216 breakpoint.h (BREAKPOINT_MAX): New define sets max length of
5217 a breakpoint instruction.
5218 breakpoint.c: struct breakpoint's shadow_contents now sized as
5220 (insert_breakpoints): Vector to target to install breakpoints.
5221 (remove_breakpoints): Vector to target here too.
5222 Remove REMOTE_SA_SPARC kludges and other remote_debugging.
5223 sparc-tdep.c (single_step): Use new breakpoint interface for
5224 the single-step breakpoints.
5225 mem-break.c (memory_insert_breakpoint, memory_remove_breakpoint):
5226 New file, contains routines to insert and remove breakpoints by
5227 reading out the old contents and later replacing them. This is
5228 how ptrace breakpoints work, and many remote systems as well.
5230 * tm-vxworks68.h: New config file, overrides a few things for
5231 Wind River's preferences.
5233 * target.h: New file, for transfer vector used to talk to the
5234 inferior (child, attached, core, exec, remote, etc). All accesses
5235 to the thing being debugged should come through these vectors.
5236 target.c: New file, routines to handle transfer vector.
5237 (various files): Add transfer vectors XXX_ops for the various
5238 targets and pseudo-targets (core files, etc) we support.
5240 * breakpoint.c (bpstat_stop_status): Further explorations of
5241 watchpoints and why things don't work all the time.
5242 (bpstat_alloc): New fn to allocate a bpstat and chain it.
5244 * config.gdb: Only add "source ${srcdir}/.gdbinit" to
5245 the local gdbinit if it doesn't already have it.
5247 * core.c (core_ops): add and install.
5248 Allow core debugging without exec file.
5250 * dbxread.c (free_and_init_header_files): Merge two fns.
5251 (end_symtab): Free named symbol table when a new version comes in.
5252 (read_dbx_symtab): Relocate all kinds of symbols with base
5253 address. First step toward handling different text, data, bss
5255 (add_file_addr_command): Renamed add_file_command.
5256 (add_file_command): Vector to remote handler.
5257 Add "load" as an alias for "add-file" command.
5259 * defs.h: Allow "volatile" to be used in non-ANSI; use it for
5260 non-returning functions.
5262 * exec.c: Add exec_ops, and push it as a target when an exec
5265 * infcmd.c (run_command): Pass executable file name and arg list
5266 separately when starting an inferior. Permit "run" when no exec
5267 file is specified, for VxWorks.
5268 (detach_command): Move to child_detach in inftarg.c.
5270 * inftarg.c: New file. Unix-child-specific routines, and the
5271 child_ops structure.
5273 * inferior.h (registers): Export "registers" as the way for
5274 target dependent register handlers to find gdb's local copy of
5275 the registers. Rename "stop_after_attach" to "stop_soon_quietly"
5276 since it is now used by places that want wait_for_inferior to
5277 handle the grunge but want to see every trap from the inferior.
5279 * inflow.c (create_inferior): Pull out, and merge into infrun.c.
5280 Eliminate remote_debugging hooks in terminal handling.
5282 * infrun.c: Replace start_inferior with child_create_inferior.
5283 Move all the hair of Unix shells and ptrace idiosyncracies into
5284 child_create_inferior, so remote handlers don't have to deal.
5285 Remove running_in_shell. Rename stop_after_attach to
5286 stop_soon_quietly, and use it in a few other places where we want
5287 to just call wait_for_inferior and get control back on the first
5288 trap. trap_expected now never takes a value > 1.
5289 (init_wait_for_inferior): Initialize static vars when a new
5292 main.c (gdbinit): Add new hook for .gdbinit file name, let
5293 it be overridden by config files as GDBINIT_FILENAME.
5294 (DEFAULT_PROMPT): Add new hook for overriding (gdb) prompt.
5295 Both of these are used for VxWorks gdb.
5297 mcheck.c: rename include file "gmalloc.c" to avoid problems
5298 with system include file "malloc.c".
5300 param-no-tm.h: New include file, same as param.h but does not
5301 include the default "tm.h" file. This is used in files where
5302 the target is known, e.g. remote-eb.c or sparc-xdep.c.
5304 param.h: Now just a shell that includes tm.h and param-no-tm.h.
5306 remote-vx.c: New file, VxWorks remote debugging support. Uses
5307 RPC routines that are shared with the target system, in directory
5310 remote.c: Vectorize remote interface.
5312 source.c: Globalize source_path, and make an alias "l" for "list"
5313 since we now have the "load" command.
5315 sparc-xdep.c: Use new param-no-tm.h.
5317 symmisc.c (free_named_symtab): Add new function from Wind River.
5318 However, ifdef it out for now while we think about what it should
5321 tm-sun3.h, xm-sparc.h, xm-sun3.h, xm-symmetry.h: Move
5323 the xm- file, and change its name to CHILD_PREPARE_TO_STORE, since
5324 non-Unix-children handle this with their own code in the target
5327 Makefile.dist: Roll version to 3.92.3. Add vx-share stuff to
5328 source and target lists. Add vx-share to default list of include
5329 directories. Add new files to src and target lists: mem-break,
5330 target, inftarg, remote-eb, remote-vx, targ-vx. Be sure the
5331 ${srcdir} versions of munch and createtags are used.
5333 * valops.c (find_function_addr): Split out of call_function.
5334 (call_function_by_hand): Rename call_function; this function
5335 calls functions in the target by laboriously patching the target
5336 word-by-word with the right stack, args, regs, etc.
5339 Mon Nov 5 17:29:10 1990 John Gilmore (gnu at cygint)
5341 Handle AMD 29000 a bit better.
5343 * remote-eb.c (readchar): Mask received char log to make it readable.
5344 (remote_start): Pass arguments down to executing program.
5345 Make startaddr unsigned.
5346 infrun.c (start_inferior): Accept args, pass them to
5348 infcmd.c (run_command): Pass args down to start_inferior.
5350 * tconfig/am29k-aout, tconfig/am29k-coff: New files specifying
5351 the target object file format.
5352 tm-29k.h: Pay heed to COFF_ENCAPSULATE.
5354 * am29k-pinsn.c (print_insn): Print 0x on hex numbers in disassembly.
5355 am29k-tdep.c (examine_prologue): Better checking of function prefixes.
5357 Sun Oct 7 18:20:45 1990 John Gilmore (gnu at cygint)
5359 * Makefile.dist (VERSION): Roll version to 3.91.9 and freeze.
5360 * TODO: We did a few things, we have more to do though.
5362 * xm-sparc.h (CLEAR_DEFERRED_STORES): Define.
5363 * inflow.c (inferior_died): Clear deferred stores.
5365 * Debug problems with dummy frames and calls to the inferior.
5366 * tm-sparc.h (PUSH_DUMMY_FRAME, POP_FRAME): Move to sparc-tdep.c.
5367 * sparc-tdep.c (do_restore_insn): Simplify.
5368 (sparc_frame_find_saved_regs): Simplify and fix what we find.
5369 (sparc_push_dummy_frame): Simplify and fix what we push.
5370 (sparc_pop_frame): Slightly more hair here, deciding whether
5371 we are restoring a saved PC or returning to a return address in %i7.
5372 * sparc-xdep.c (read_inferior_registers): Debug if valid reg is read.
5374 * utils.c (xmalloc, xrealloc): Return type depends on __STDC__.
5375 * symtab.h (xmalloc): ditto, for obstack_chunk_alloc.
5376 * obstack.h (chunkfun): ditto.
5377 * defs.h (xmalloc, xrealloc): ditto
5379 * utils.c (quit): Grab the terminal from the child if necessary.
5381 * inflow.c (term_status_command): Rename to term_info, change
5384 * sparc-pinsn.c (print_insn): Disassembly prefers real instructions.
5385 (is_delayed_branch): Speed up.
5386 * sparc-opcode.h: Add ALIAS bit to aliases. Fix up opcode tables.
5387 Still missing some float ops, and needs testing.
5389 * Support for input and output radixes other than base 10
5390 * defs.h (input_radix, output_radix): Declare.
5391 * expread.y (yyparse, parse_number): Handle changes of input
5392 radix, and ambiguous names-or-numbers in radixes >10.
5393 * printcmd.c (print_scalar_formatted): Print formatted hex
5394 numbers in varying column widths.
5395 * valprint.c (val_print): Use output_format to print scalar ints.
5396 (set_input_radix, set_output_radix, set_radix): Create.
5397 (set_output_radix): Set output_format from output_radix.
5398 (_initialize_valprint): add `set radix' but leave the others off.
5400 * main.c (execute_command): Let stupid questions be turned off.
5401 (_initialize_main): Handle "set stupidity", etc.
5403 * main.c, inflow.c, inferior.h, frame.h, command.c, defs.h,
5404 sparc-pinsn.c, sparc-xdep.c, value.h, valops.c, values.c: Lint.
5406 Tue Oct 2 11:20:02 1990 John Gilmore (gnu at cygint)
5408 * TODO, Makefile.dist, ChangeLog: Freeze for 3.91.8 release.
5409 bfd stuff is still screwed up, but with some manual work, it
5412 * breakpoint.c (bpstat_do_actions): Start over if a command
5413 proceeds the inferior, since the inferior will have stopped and
5414 will need to have its new stop-actions taken care of.
5416 * dbxread.c (read_struct_type): Expression gives Sun3 4.0.3
5417 compiler fits, simplify it.
5419 * gdb.texinfo (directory command): Doc new dir command.
5420 source.c (directory_command): "dir" now puts things on the front
5421 of the path, moves dups up front, and handles multiple names
5422 on the command line, inserting each one in order. It also
5423 blows away cached line and full_filename info.
5425 * stack.c (backtrace_command): Skip "more stack frames follow"
5428 * Change #ifndef HAVE_VPRINTF to #define MISSING_VPRINTF in
5429 xm-convex.h, xm-hp300bsd.h, xm-isi.h, xm-merlin.h, xm-news.h,
5430 xm-np1.h, xm-pn.h, xm-pyr.h, xm-symmetry.h, xm-umax.h, xm-vax.h.
5431 The only odd one was Gould NP1, which had defined vprintf to
5434 * Merge Ted Goldstein <tedg@Eng.sun.com>'s changes for epoch.
5435 printcmd.c (print_command_1): Pass 'inspect' flag down as a global
5436 variable, inspect_it.
5437 valprint.c (print_string, val_print): Use the global inspect_it
5438 to indicate whether to print in Epoch style or normal style.
5440 Mon Oct 1 23:55:26 1990 John Gilmore (gnu at cygint)
5442 * printcmd.c (call_command): add an alias for the "print" command
5443 which runs expressions and doesn't print the result if void.
5444 (print_command_1): implement it.
5446 * command.c: Remove #if 0'd code. Initialize all the fields
5447 in add_cmd (). Rename do_nothing_command to
5448 not_just_help_class_command, and make it externally visible.
5449 command.h: add user_commands to struct.
5450 * main.c (define_command): Don't overload c->function with a char
5451 string as well as a function pointer.
5453 * eval.c (evaluate_subexp): Reinstall tiemann changes to
5454 calling convention of value_struct_elt () that got dropped in
5457 * tm-sparc.h (FRAME_FIND_SAVED_REGS): move to sparc-xdep.c.
5458 sparc-tdep.c (sparc_frame_find_saved_regs): ditto.
5460 * tm-sparc.h (POP_FRAME): replace some constants with defines.
5462 * sparc-xdep.c (store_inferior_registers): defer stores to regs
5463 until a good time (e.g. when we are about to run the child),
5464 saving ptrace calls.
5465 * infrun.c (proceed): handle DO_DEFERRED_STORES.
5466 * tm-sparc.h: define DO_DEFERRED_STORES.
5468 * sparc-xdep.c (store_inferior_registers): when storing float
5469 registers, don't store stack regs too. When storing the SP,
5470 however, DO store the stack regs too. This fixes a bug in which
5471 the dummy frame is not recognized when a call_function finishes,
5472 because its frame pointer (in the stack regs) was never
5474 (read_inferior_registers): Mark WIM and TBR and FPS and CPS valid
5475 even though we don't know how to read them from an inferior.
5476 valops.c (call_function): Comment about storing SP.
5478 * infrun.c (save_inferior_status): Save away the original bpstat
5479 chain so it can be restored later. Install the copied version for
5480 use by whoever saved the status. It will be blow away by
5481 restore_inferior_status, and the original chain restored. This is
5482 important for people who have pointers into the original.
5484 * breakpoint.c, command.h, copying.awk, dbxread.c, defs.h,
5485 findvar.c, frame.h, obstack.h, obstack.c, inflow.c, value.h,
5486 main.c, printcmd.c, sparc-tdep.c, symtab.c, valprint.c: lint
5489 Fri Sep 28 20:32:46 1990 John Gilmore (gnu at cygnus.com)
5491 * Makefile.dist: Roll version to 3.91.8. Add bfd.h and bfdconfig.h
5492 temporarily to the makefile. Add am29k-opcode.h and WHATS.NEW.
5493 Add stuff.c and kdb-start.c to the OTHERS list for tar files.
5495 Fri Sep 28 19:12:12 1990 John Gilmore (gnu at cygint)
5497 * Merge Mike Tiemann's multiple inheritance changes from Sun.
5498 Store the baseclasses in a type struct starting from array element
5499 0 rather than from the unusual array element 1.
5501 dbxread.c: the above.
5502 (virtual_context): Add
5503 Read new debug information about which virtual function table
5504 a virtual function is from, and store it in fn_field.fcontext.
5506 symtab.h: Add fcontextt. Fix baseclass indices. Typo in
5507 TYPE_FN_FIELD_STATIC_P.
5509 symtab.c: the above.
5510 valops.c: the above. Handle pointer casts of object *'s.
5511 (search_struct_method): Add.
5512 (value_struct_elt): First arg is now a pointer to a value, and is
5515 valprint.c: the above.
5516 values.c (value_virtual_fn_field): Add type arg. Handle
5517 offsetting to the proper object when calling virtual fns.
5519 (baseclass_addr): Add valuep arg.
5521 * README: Document the current state of BFD config (missing).
5522 * TODO, ChangeLog, Makefile.dist: Roll version.
5523 * WHATS.NEW: Add summary of changes since 3.5.
5525 Thu Sep 27 16:23:12 1990 John Gilmore (gnu at cygint)
5527 * dbxread.c (read_struct_type): Clear bit vectors whenever
5529 symtab.c (B_CLRALL): define.
5531 * tm-sparc.h (STORE_RETURN_VALUE): Avoid clobbering types by
5532 using == rather than =. Huh... This fixes the dreaded problem
5533 wherein builtin_type_int becomes TYPE_CODE_FLT.
5535 * core.c (info_files): Show the inferior pid.
5537 * config.gdb: Avoid putting "dir" command into .gdbinit. GDB
5538 already knows how to look in the source directory.
5540 * Remove psymtab hair from many places. Remove duplicated code
5541 for searching symbol tables. Hide psymtabs from most places.
5542 Make it fast to get from a psymtab to its symtab.
5544 blockframe.c (blockvector_for_pc): Remove psymtab hair.
5545 coffread.c (psymtab_to_symtab): Rename to psymtab_to_symtab2.
5546 mipsread.c (psymtab_to_symtab): Rename to psymtab_to_symtab2.
5547 dbxread.c: export psymtab_to_symtab, make it work if called N times.
5548 (psymtab_to_symtab): Rename to psymtab_to_symtab2. Initialize
5549 new symtab completely. New psymtabs get symtab pointer
5550 initialized to zero. Remove MI warning printf.
5551 symtab.h: Comments. Add psymtab to symtab pointer.
5552 (PSYMTAB_TO_SYMTAB): New macro.
5553 symtab.c: use PSYMTAB_TO_SYMTAB. Add psymtab_to_symtab and export it.
5554 source.c: use PSYMTAB_TO_SYMTAB. Remove symtab version and
5556 stack.c (backtrace_command): Avoid pre-pass to read symbols, if
5558 (print_frame_info): Avoid special-casing symbols that have not yet
5561 * source.c (open_source_file): Quick path if we have already
5562 located the source file by its full name.
5564 * symtab.c (lookup_symbol): Use find_pc_symtab rather than
5565 find_pc_psymtab. When a name is found in the misc function
5566 vector, search the symbol table for its mangled name, not the
5567 name that the user typed.
5569 * bfd.h: Fix missing comment terminators, make #endifs match.
5571 * valarith.c (value_less): Handle unsigned int comparisons.
5572 Add FIXME about pointer compares, which assume host and target
5573 pointers are the same.
5575 * command.c (do_nothing_command): lint
5576 dbxread.c: lint. Remove sort_syms. Document C++ visibility info,
5577 fix comments on debug symbol format for visibility. Actually set
5578 visibility of symbols.
5579 main.c (echo_command): lint; use <readline/history.h>.
5580 tm-sparc.h (FRAME_FIND_SAVED_REGS): lint
5581 obstack.h (_obstack_blank): Rearrange pointer math to avoid
5582 pointing past end of allocated memory; saber complains.
5583 obstack.h: Declare the external functions that we use.
5584 valarith.h: use <string.h>
5585 solib.c (solib_add): lint.
5587 Fri Sep 21 17:05:19 1990 John Gilmore (gnu at cygint)
5589 * main.c (initialize_main): Default info_verbose to off, now that
5590 symbol reading is fast.
5591 (quit_command): Avoid clobbering exec_bfd while quitting.
5593 * Initial BFD (binary file diddling library) merger:
5594 coffread.c: Change AOUTHDR to struct exe_hdr.
5596 core.c: initialize initialized data at compile time.
5597 (core_file_command): Move from coredep.c, convert to bfd.
5598 (xfer_core_file): Convert to bfd.
5599 exec.c (exec_file_command): use bfd routines.
5601 mips-tdep.c: Remove exec_file_command and friends.
5604 * coredep.c: (fetch_core_registers) Convert core_file_command to
5605 fetch_core_registers.
5606 mips-xdep.c, sparc-xdep.c, sun3-xdep.c: ditto.
5608 * utils.c: (error): Bogus crap, FIXME, to print bfd errors.
5609 (my_bfd_read): More bogosity, which I don't think we call.
5610 (program_name): Remove this atrocity asap!
5612 Wed Sep 19 13:36:41 1990 John Gilmore (gnu at cygint)
5615 values.c: allocate_repeat_value was not clearing the
5616 optimized_out field.
5617 (value_static_field): minor stylistic fix (wrong macro was used).
5618 valops.c (value_struct_elt_for_address): didn't work for C++
5621 * signame.c (_initialize_signame): Initialize signal names once.
5623 * breakpoint.h, command.c, copying.awk, defs.h, environ.c,
5624 exec.c, frame.h, infcmd.c, inferior.h, main.c, munch, sun3-xdep.c,
5625 symtab.h, tm-29k.h, valprint.c, value.h, values.c: Lint.
5627 * remote-eb.c: Support user-settable baud rates on the serial port.
5629 * tm-sun3.h (PREPARE_TO_STORE): fix typo.
5631 Fri Sep 14 13:28:29 1990 John Gilmore (gnu at cygint)
5633 * tconfig/sun3os4: Remove warning about native assembler,
5634 since it also occurs in the xconfig file.
5636 * findvar.c (registers): Allocate some slop after `registers'
5637 to prevent stray accesses from trashing the next variable.
5639 * tm-68k.h (REGISTER_BYTES): Allocate the right number of bytes
5640 on the sun-3, by changing the #ifdef from `sun3' (which is not
5641 defined by cc) to `sun'. Symptom was trashed builtin_type_XXX
5642 vars, which happened to follow `registers' in the executable.
5644 * readline/history.c (history_search): Heed gcc-2's advice
5645 and parenthesize && inside ||).
5647 * am29k-opcode.h, am29k-pinsn.c, am29k-tdep.c, remote-eb.c,
5648 tm-29k.c: Insert FSF copyright headers.
5650 * remote-eb.c: Better comments.
5652 * Makefile.dist: Update to 3.91.6.
5653 * TODO: note PREPARE_TO_STORE problem.
5655 Thu Sep 13 09:52:33 1990 Jim Kingdon (kingdon at cygint)
5657 * stack.c (frame_info): Only use FRAME_FIND_SAVED_REGS if defined.
5659 * remote.c: Wrap the whole file in #if !defined (SPECIAL_REMOTE).
5661 * infrun.c (wait_for_inferior, at end): Don't set up
5662 prev_* if the inferior no longer exists.
5664 * inferior.h (CALL_DUMMY_LOCATION): New macro, to replace
5665 CANNOT_EXECUTE_STACK.
5666 valops.c (call_function): Use it.
5668 * tm-convex.h: Add CALL_DUMMY_LENGTH for use by PC_IN_CALL_DUMMY.
5670 * inferior.h (PC_IN_CALL_DUMMY): New macro.
5671 infrun.c (wait_for_inferior, 2 places): Use it.
5673 * values.c (value_being_returned): Only use
5674 EXTRACT_STRUCT_VALUE_ADDRESS if defined.
5676 * Move PREPARE_TO_STORE from xm-sun3.h to tm-sun3.h to do the
5677 right thing for remote-eb.c.
5679 * sun3-xdep.c: Remove extraneous call to remote_store_registers.
5680 * sun386-xdep.c, hp300hpux-xdep.c, sparc-xdep.c: Ditto.
5682 * blockframe.c: Put get_frame_saved_regs inside #if !defined
5683 (FRAME_FIND_SAVED_REGS).
5685 * findvar.c ({fetch,store}_registers): Check for
5686 REMOTE_{FETCH_STORE}_REGISTER macro.
5688 * findvar.c (get_saved_register): Add argument lval and
5689 change meaning of argument addr.
5690 findvar.c: Change calls to get_saved_register to reflect
5691 new calling convention.
5692 valops.c (value_assign): Use get_saved_register instead of
5693 find_saved_register.
5695 Sun Sep 2 12:40:20 1990 Jim Kingdon (kingdon at cygint.cygnus.com)
5697 * coffread.c (read_one_sym): Make temp_aux an AUXENT, not
5698 an (uninitialized) pointer to one. Use "&" when passing it
5701 Fri Aug 31 22:57:54 1990 Jim Kingdon (kingdon at cygint.cygnus.com)
5703 * coffread.c (getfilename): Use DGUX x_offset and x_name if
5706 * coffread.c (symbol_file_command): Put semicolon after
5708 Put safe_to_init_tdesc_context in #if defined (TDESC).
5709 Put #ifdef TDESCs in 1st column for non-ANSI cpp's.
5710 coffread.c: #include <sys/stat.h>.
5711 (read_coff_symtab): Typo: in_source_files -> in_source_file.
5712 Add missing ')' in check for "lc%" and friends. Remove
5714 Declare read_one_sym() at top of file.
5715 (read_file_hdr): Put in extra #ifdefs so MC68MAGIC and
5716 MC68WRMAGIC can have the same value without causing a duplicate
5719 Thu Sep 13 15:55:36 1990 John Gilmore (gnu at cygint)
5721 * Allow a Makefile to be built without building the
5722 tm and xm file links that screw up builds in subdirectories.
5723 This is done with `config.gdb none', then you can do things
5724 like `make gdb.tar.Z'.
5725 * tconfig/none: Config file for no target system
5726 * xconfig/none: Config file for no host system
5727 * config.gdb: If no TM or XM files are called out by the
5728 host or target file, don't make links for them.
5730 * cplus-dem.c: Add documentation.
5732 * dbxread.c (read_ofile_symtab): Turn a fatal error into a
5733 simple error, so the user's gdb doesn't crash due to some object
5734 file problem (e.g. somebody is rebuilding the file out from under
5737 * printcmd.c (print_address_symbolic): demangle the symbol.
5739 * Makefile.dist (OTHERS): Remove tdesc-lib because it has
5740 Motorola copyrights in it. Make "make gdb.tar.Z" work.
5741 (alldeps.mak): sort and uniq all results from this; duplicates
5742 hose gdb.tar.Z link building. Remove RCS files from
5743 tconfig and xconfig. Add config files for sun386. Add
5744 a few odd files to OTHERS and HFILES.
5746 Mon Sep 10 21:20:24 1990 John Gilmore (gnu at cygint)
5748 * Makefile.dist: Pull solib.c to tconfig/sun?os4.
5749 Roll version number to 3.91.5. Make lint work in bindir.
5751 * README: Document cross-debugging and new file structure.
5753 * blockframe.c: Lint. Include "value.h" to declare read_register.
5754 (find_pc_partial_function): remove duplicate line.
5756 * command.h: Lint. Declare error_no_arg and dont_repeat.
5758 * tm-news.h: Remove inadvertently duplicated stuff.
5760 * mipsread.c: Remove cache_pc_function stuff, now done cleanly.
5761 Clean up usage of misc_function_type. Declare some CORE_ADDRs.
5763 * config.gdb: Allow `config.gdb host target' form. Clean
5764 up previous change that printed bogus messages when you just said
5767 * core.c: #include "command.h" for lint.
5770 * main.c: Remove some casts of enums. Lint.
5777 * printcmd.c (initialize_printcmd): Fix thinko in inspect cmd.
5779 * sparc-tdep.c (isannulled): Take instruction as parameter, don't
5780 read it from memory. This will allow us to save ptrace calls
5781 eventually. Changed caller single_step too.
5783 * sparc-xdep.c (fetch_inferior_registers): Avoid reading regs
5784 that we aren't going to use, saving many ptrace calls, especially
5785 when watchpointing or single stepping. Use some #define's for
5787 (store_inferior_registers): Ditto.
5788 (core_file_command): Use some #define's for constants.
5790 * tm-sparc.h: Add #define's for some register numbers, so we
5791 can eliminate the use of random constants in sparc-xdep.c.
5793 * stack.c (frame_command, print_frame_info, up_command,
5794 down_command) Remove frame_changed, since it
5795 causes a bug and doesn't seem to do anything useful. In some
5796 places it was used as a flag, in others as a stack level (?).
5798 * utils.c: Use MISSING_VPRINTF rather than HAVE_VPRINTF, so the
5799 default is to use the portable (vprintf) version rather than the
5801 * xm-news.h (MISSING_VPRINTF): Add.
5803 * valprint.c (val_print): Demangle fancy vtbl printouts. Lint.
5805 Sat Sep 8 00:24:12 1990 John Gilmore (gnu at cygint)
5807 * Remove stuff that forces -Bstatic linking of gdb, and warnings
5808 about linking debugged programs -Bstatic in the sun?os4 config
5809 files in tconfig and xconfig subdirectories.
5811 * main.c (main): Remove unreached exit(0) now that we exit
5814 * Create TODO file for online bug list. There are too many
5815 "little" bugs to keep track of on paper.
5817 * Change Projects file to refer to bug-gdb@cygnus.com
5818 rather than kingdon@ai.
5820 Fri Sep 7 23:35:15 1990 John Gilmore (gnu at cygint)
5822 * Makefile.dist (VERSION): 3.91.4 now.
5824 * symtab.c (init_misc_bunches): Rename from init_misc_functions.
5825 (condense_misc_bunches): Add sanity check that misc_count is
5826 the same as the number of symbols in the bunch.
5828 * coffread.c: rename init_misc_bunches. Pass an argument
5829 to condense_misc_bunches (a zero).
5831 * dbxread.c (partial_symbol_file_read): Call init_misc_bunches
5832 every time we are called; don't rely on our caller to do it.
5833 (add_file): Remove call to init_misc_bunches.
5835 * mipsread.c: Only warn, don't error, if unknown symbol types.
5836 This keeps an old gdb from falling on its face if it sees newly
5837 extended symbol info. Rename init_misc_bunches.
5839 Fri Sep 7 22:58:15 1990 John Gilmore (gnu at cygint)
5841 * Merge in changes from Per Bothner for DECstations and other
5842 MIPS stuff. The rest is Bothner speaking:
5844 The next message is a merger of Alessando Forin's mips port with
5845 mine. I've tried to use my good if biased judgment to get
5846 the best of both. It *does* need testing.
5848 Some of the changes are general, *not* mips-specific.
5851 Didn't believe in little-endian bit order.
5852 There are still inconsistencies about whether flags
5853 like BITS_BIG_ENDIAN are integer (#if ...) or
5854 boolean (#ifdef ...). I tried to paper over them.
5856 dbxread.c,coffread.c,mipsread.c,symtab.c,symtab.h:
5857 Moved some misc_function code that was common to
5858 {dbx,coff,mips}read.c to symtab.c.
5859 In the process, I think I cleaned things up a bit.
5860 At the same time, moved obsavestring and obconcat to symtab.c.
5863 Removed obsolete condense_addl_misc_bunches (use
5864 condense_misc_bunches(1) instead).
5867 Needed to include <sys/dir>, at least on DECstations.
5869 valops.c, mips-tdep.c, tm-mips.h:
5870 Added PUSH_ARGUMENTS macro to support funny argument-pushing
5871 conventions (when STACK_ALIGN is insufficient).
5872 Needed on mips, where doubles need 8-byte alignment,
5873 but ints only need 4.
5876 Removed cruft that was not being used.
5877 Merged in many fixes (most from Frank Yellin, fy@lucid.com).
5880 Print $ before register-names (I think that makes things a little
5882 Never print two instructions, even if one delays.
5883 Removed hex-disassemble set_cmd. (This is not mips-specific,
5884 so I think the argument is whether it is generally worthwhile or not.
5885 I'm inclined to think not, given how easy it is to
5886 convert between radixes in gdb.)
5889 This is basically Alessando's code.
5890 It doesn't use obstacks; I changed it to use obstacks
5891 in a few minor places where using malloc causes a
5892 memory leak. (Probably, more places could/should be changed.)
5893 I added record_misc_function where it was missing.
5894 In symbol_file_command and add_file_command, I tried
5895 to make the code consistent with more recent versions.
5896 Minor sylistic changes in parse_procedure.
5897 Make a .gdbinfo. psuedo-symbol point back to the real
5898 procedure symbol (using the isym field).
5901 This is basically from my port, but with a lot of details
5902 and a number of routines merged in from Alessando's version.
5903 I basically used my code "raw" backtrace (use heuristics
5904 from the actual code, rather than symbol table info) - though
5905 the idea is Alessandro's. I feel my code is a little cleaner
5906 here, particularly in being a little more flexible, such as being
5907 able to handle gcc-produced code (which it now can).
5908 It also doesn't do frame caching (which is not useful
5909 more recent gdb versions).
5910 I also used my code for push_/pop_dummy, more or less.
5911 I tried to incorporate AF's code for testing sigtramp
5912 while backtracing; I probably got it wrong.
5913 Added mips_print_register, which tries to scrunch as much
5914 information as possible on a screen...
5915 Removed the skip-prologue set_cmd. As with hex-disassemble (see
5916 under mips-pinsn.c), I don't see anything mips-specific here,
5917 and I don't see it being all that useful anyway.
5920 Added a $fp psuedo-reg distinct from $fp (nice for gcc).
5921 Use more register names (rather than hard-cases numbers).
5923 Thu Sep 6 18:33:15 1990 John Gilmore (gnu at cygint)
5925 * Hack up 3.90.11 changes:
5927 * Makefile.dist (depend): parameterize $(GCC).
5928 Add solib.c and solib.o.
5929 (readline): Fix vpath for both absolute or relative SRCDIR.
5931 * blockframe.c: Fix from Schaefer@asc.slb.com for shared libs.
5932 Also, let the part I didn't understand at least compile so
5933 I can test the rest. FIXME.
5935 * dbxread.c: Fix thinko using strcmp.
5936 (init_psymbol_list): declare static.
5937 (partial_symbol_file_open): Comment cleanups better, avoid
5938 cleaning up the string table since the caller will do that.
5939 Move the stat for mod time into symbol_file_command, temporarily.
5940 (There should be a mod time for each symbol file, eventually,
5941 to control its rereading. FIXME.)
5943 * infptrace.c (PT_WRITE_D): use same value as PT_WRITE_I for
5944 SunOS, which gives error for shared libs otherwise. (From
5945 Schaefer, probably FIXME needs work for portability.)
5947 * solib.c: Move #include "param.h" to work.
5948 Lowercase all the Uppercase Letters In the Messages.
5949 (find_solib): Clean up inferior_so_name for debug printouts.
5950 Allow no argument, to mean all shared libraries.
5952 * symmisc.c: include param.h to get CLEAR_SOLIB.
5954 Wed Sep 5 18:00:08 1990 John Gilmore (gnu at cygint)
5956 * Merge in Kingdon's changes from FSF: the diffs from 3.90.9
5957 to 3.90.11. ChangeLog entries below are from this.
5959 Wed Jun 13 09:17:39 1990 Jim Kingdon (kingdon at mole.ai.mit.edu)
5963 * Makefile.dist (HFILES): Add tm-sunos.h.
5965 Tue Jun 12 16:15:26 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5969 * Makefile.dist (gdb.tar.Z): Change linking of config so it works.
5971 Thu Jun 7 16:22:27 EDT 1990 Jay Fenlason (hack@ai.mit.edu)
5973 * sparc-opcode.h Added single-operand version of rett.
5975 Mon Jun 4 18:12:31 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5977 * m-sparc.h (REG_STRUCT_HAS_ADDR, STRUCT_ARG_SYM_GARBAGE):
5978 Put parens around gcc_p in expansion.
5980 Thu May 24 15:44:51 1990 Jim Kingdon (kingdon at mole.ai.mit.edu)
5982 * utils.c (lines_to_list): Return 10 if lines_per_page == 0.
5984 Wed May 23 16:36:04 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5986 * Changes for Sun shared libraries:
5987 blockframe.c (find_pc_partial_function): If a non-text symbol
5988 is found, set *address = pc - FUNCTION_START_OFFSET.
5989 breakpoint.c (insert_breakpoints) [DISABLE_UNSETTABLE_BREAK]:
5990 Disable breakpoints instead of giving an error.
5991 source.c (select_source_symtab): Initialize cs_pst.
5992 symmisc.c: Call CLEAR_SOLIB if defined.
5993 symtab.h: Make text{low,high} CORE_ADDR not int.
5994 (psymtab): New field addr.
5996 dbxread.c: Move DECLARE_FILE_HEADERS outside functions.
5997 (record_misc_function): Give correct type for N_DATA symbols.
5998 (condense_misc_bunches): do "misc_function_count = j" regardless
6000 Take code which is shared between symbol_file_command and
6001 add_file_command and put it into partial_symbol_file_{open,read}.
6002 Split add_file_command into add_file_command and add_file.
6003 Make psymtab_to_symtab read in the string table if the file
6005 Two new parameters to read_dbx_symtab and start_psymtab.
6006 tm-sunos.h: New file.
6008 Tue May 22 17:43:03 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
6010 * infcmd.c: Change cont_command to continue_command and "cont"
6013 Mon May 21 14:41:41 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
6015 * breakpoint.c (enable_breakpoint): Get value of watchpoint.
6017 * defs.h [sparc]: Use <alloca.h> regardless of __GNUC__.
6019 * values.c (USE_STRUCT_CONVENTION): Check for structures of
6020 size 1,2,4,8 rather than size < 8.
6022 * dbxread.c (dbx_lookup_type): Do f->length *= 2 as many times
6023 as necessary, not just once.
6025 * sparc-opcode.h: Add a bunch of new opcodes which Sun as supports.
6027 Thu May 17 15:04:09 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
6029 * {t,x}m-sun386.h, sun386-xdep.c, {x,t}config/sun386
6031 * tm-news.h: Add CALL_DUMMY_*.
6033 * tm-68k.h: Remove duplicate comment at FRAME_FIND_SAVED_REGS.
6035 * config.gdb: In list_host, list_target, use ${i}, not $i.
6037 Tue May 15 21:27:12 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
6039 * source.c (find_source_lines) [BROKEN_LARGE_ALLOCA]: Use xmalloc.
6041 * sparc-opcode.h: Change all store floating-point state register
6042 instructions to have the right match & lose fields.
6044 Sat May 5 12:39:18 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
6046 * Makefile.dist: Move -I${srcdir} to GLOBAL_CFLAGS and pass
6048 config.gdb: If srcdir != ., create readline directory and
6049 copy a makefile into it.
6051 * wait.h, infrun.c: Change WRETCODE to WEXITSTATUS for
6052 consistency with POSIX.
6054 * breakpoint.c (bpstat_stop_status): Disable watchpoint
6055 when we exit its exp_valid_block.
6057 Tue Sep 4 11:46:46 1990 John Gilmore (gnu at cygint)
6059 * Makefile.dist: Bump version to 3.91.3.
6061 * Clean up handling of breakpoint commands (somewhat).
6062 Prompted by Tiemann bug report "cont 10" doesn't work any more.
6064 inferior.h: Add breakpoint_proceeded to inferior status struct
6065 and globals; save it and restore it.
6066 (clear_breakpoint_commands): Cleanup, remove old #define.
6068 infrun.c (clear_proceed_status): Set breakpoint_proceeded.
6069 (save_inferior_status, restore_inferior_status): handle it also.
6070 (proceed): Remove earlier code that set breakpoint_proceeded.
6071 It is now set only in clear_proceed_status.
6072 (clear_proceed_status): Cleanup, use bpstat_clear rather
6073 than clear_breakpoint_commands. No callers need the stop_bpstat
6074 between clear_proceed_status and proceed.
6076 infcmd.c: Add breakpoint_proceeded definition and comment.
6077 (cont_command, jump_command, signal_command): Move call to
6078 clear_proceed_status right next to call to proceed.
6080 breakpoint.c (bpstat_do_actions): Avoid clobbering our
6081 caller's argument while running down the chain of breakpoints.
6082 Use new variable "breakpoint_proceeded" to determine when
6083 a command that it executes moves the inferior past the
6085 (bpstat_clear): Handle NULL argument.
6086 (bpstat_clear_actions): Avoid useless call to
6087 breakpoint_auto_delete.
6088 (delete_breakpoint): Clean up bpstat's that are pointing to
6089 the deleted breakpoint from the stop_bpstat chain.
6090 (breakpoint_auto_delete): Simplify.
6092 * Clean up handling of EOF, error on stdin, etc. This was
6093 prompted by a network problem that caused gdb to go into an
6094 infinite loop filling up its malloc'd memory.
6096 main.c (return_to_top_level): Cleanup: call bpstat_clear_actions,
6097 not clear_breakpoints_commands, which is now gone.
6098 (main): If command_loop returns (e.g. from EOF on stdin), do
6099 a quit_command (looping back to command_loop if quit_command
6100 doesn't really quit).
6101 (command_loop): check result from command_line_input and
6102 exit if it returns NULL, rather than passing the NULL to
6104 (gdb_readline): Free malloc'd result space before returning
6107 * utils.c (query): Handle C-d to mean "yes", just as if the
6108 input was not a terminal. Also avoid infinite loop if EOF
6109 occurs in mid-input-line before newline. This allows
6110 query to be used at EOF on stdin with reasonable results.
6112 * infrun.c (proceed): Set breakpoint_proceeded.
6114 * values.c (value_as_long): Avoid infinite recursion for enums.
6115 (_initialize_values): Fix typo in help msg (kingdon).
6117 * Makefile.dist (RL_LIB): Use RL_LIB_DEP for dependencies,
6118 RL_LIB for linking. This allows -lreadline for linking
6119 and nothing for dependencies, once readline is a real library.
6121 * config.gdb: Jim Kingdon: give useful error message if the
6122 host or target type is not recognized.
6124 * defs.h (alloca): SPARC <alloca.h> does not declare alloca,
6125 it just defines it. Dumb, but deal with it.
6127 * Jim Kingdon suggests:
6128 in xconfig/sun3os4, CFLAGS should be XM_CFLAGS.
6130 Wed Aug 29 18:03:27 1990 John Gilmore (gnu at cygint)
6132 * Makefile.dist (VERSION): Bump version # to 3.91.2.
6134 * Clean up Bothner's changes.
6136 * blockframe.c (clear_pc_function_cache): New function.
6137 * blockframe.c: remake cache_pc_function_* static.
6138 * dbxread.c (symbol_file_command): remove references to
6139 cache_pc_function_* variables.
6140 * dbxread.c (read_struct_type): Use VOFFSET_STATIC.
6141 * printcmd.c: Avoid kludging a global variable (addressprint)
6142 to avoid printing the address of a string twice. Instead,
6143 pass the format letter 's' down low enough that it can be seen
6144 to avoid this problem.
6145 (print_formatted): Pass format arg to value_print.
6146 (restore_addressprint): Remove function.
6147 (do_examine): Avoid hacking addressprint, cleanups and such.
6148 (print_frame_args): Add a comment to a Bothner change.
6149 * symtab.h: define VOFFSET_STATIC and use it instead of "-1".
6150 * symmisc.c (free_all_symtabs): Call clear_pc_function_cache
6151 to wipe out the values cached in blockframe.c.
6152 * symtab.c (find_method): Add comment saying how big you must
6153 allocate to be "big enough". Per being terse again.
6154 * valprint.c (val_print): Handle format letter "s" to print
6155 strings without addresses. Add comment to vtbl printing code
6156 which casts with wild abandon. Rearrange reference-printing
6158 @0xaddr: value (print w/addressprint)
6159 value (print w/~addressprint)
6160 @0xaddr (parameter lists w/addressprint)
6161 or nothing (parameter lists w/o addressprint)
6163 Tue Aug 28 10:47:18 1990 John Gilmore (gnu at cygint)
6165 * Merge more changes from Per Bothner:
6167 Gdb's handling of TYPE_CODE_REF was so counter-C++ (and otherwise
6168 annoying) that I tried to improve it. Here are my suggestions.
6170 These patches all attempt to handle TYPE_CODE_REF (as in C++) better.
6173 Do automatic de-reference when taking the address of a reference.
6175 Don't deref_ref when printing parameter lists.
6177 More attempts at treating refernences properly.
6179 In val_print, if deref_ref==0, don't print dangling " = ".
6181 Add COERCE_REF macro, which de-references an REF.
6183 * Merge changes from Per Bothner:
6185 * Fixed (Sony news)-specific configuration problems.
6186 * Fixed other problems with using vanilla pcc and libc (enum problems;
6187 assumption that vsprintf exists).
6188 * Some major speed-ups (finc_pc_partial_function now caches a match;
6189 parsing avoids duplicate symbol_lookup calls).
6190 * Changed handling of baseclasses (no longer use baseclasses field
6191 of struct type, use the first n_baseclasses fields instead).
6192 * Various minor changes/fixes, most C++-related.
6195 Cache the most previous match from find_pc_partial_function.
6196 (Save both low and high ends of matching function's pc range.)
6197 This speeds up the loop of infrun.c:wait_for_inferior quite
6198 a bit, and makes step/next commands much zippier.
6200 Added an enum->int cast (otherwise, some compilers barf).
6202 No longer set baseclass offset to 0, since multiple
6203 inheritance now mostly works.
6204 Added a number of casts, to shut up compiler warnings
6205 (after stabs where made enums, not ints).
6206 When discarding a symbol table (in symbol_file_command),
6207 must clear the cache introduced in blockframe.c.
6208 Don't convert $vtbl_ptr_type to vtbl any more.
6209 Get rid of TYPE_BASECLASEES and baseclass_vec (see also symtab.h).
6210 Mask off sign bit emitted by g++ for virtual table offset.
6211 Set voffset to -1 (not 1) for static member functions.
6213 Changed parsing/lexing of names to avoid doing symbol lookup twice
6214 (once when lexing to determine symbol class, once for real).
6215 Now only call symbol_lookup once. Fields of 'this' win especially big.
6217 Subpress printing addr twice in the case of 'x/s addr'.
6219 lookup_basetype_type is no longer used.
6220 Add find_methods as recursive helper function to decode_line_1.
6221 This allows multiple inheritance to work.
6222 Also, once one or more matches has been found, do not look in
6223 base-classes. (Baseclass methods would be overridden, anyway.)
6225 Removed baseclasses array in struct type.
6226 Instead of using baseclasses[i], use fields[i-1].
6227 Added virtual_field_bits[i] to indicate if the i'th baseclass is virtual.
6228 Changed sign convention of voffset (previous was inconsistent).
6230 Some macros (CALL_DUMMY and relatives) were missing. Put them back.
6232 Used to assume existence of vsprintf. Re-written to not need it
6233 if HAVE_VPRINTF is undefined.
6235 typecmp was too pessimistic. Made it less so.
6237 Don't print space after address.
6238 If vtable points to a misc symbol (with 0 offset), print it,
6239 since that indicates the actual class of the object.
6240 Changed ype_print_derivation_info to use new inheritance
6241 scheme (without baseclasses vector).
6243 In value_primitive_field, fixed some bugs left over from previous set of fixes.
6244 Also, changes needed because TYPE_BASECLASSES were removed.
6246 REGISTER_U_ADDR didn't work for PC. Rewrote to use an array.
6248 Tue Aug 21 20:08:54 1990 John Gilmore (gnu at cygint)
6251 If there is no path set, and the symbols don't indicate what directory
6252 a file was compiled in, look in the current directory. But either
6253 a path or a known compilation directory will prevent this.
6256 Three independent bug fixes:
6257 * Remove the #if 0 block that breaks some stuff.
6258 * SunOS 4.1 fixed the promoted-parameter-wrong-addr bug in Sun C;
6259 adapt gdb to either SunOS 4.0.* or 4.1.
6260 * MAX_OF_TYPE and MIN_OF_TYPE thinko. By tedg@sun, I think.
6263 Instantiate the class T when looking for methods in it. (Tiemann@sun)
6266 (type_print) Demangle the name being printed.
6267 (type_print_base) Handle botched demangling without coredump (tiemann).
6270 (check_stub_method): Document routine.
6271 (tiemann) fix bug for no-arg functions
6272 Avoid clobbering beyond end of malloc'd storage.
6273 Terminate the argument list properly.
6275 Sat Aug 18 01:29:59 1990 Per Bothner (bothner@cs.wisc.edu)
6277 * Changes merged by John Gilmore:
6280 In breakpoint_1, use new print_address_symbolic instead
6281 of find_pc_partial_function. (This forces use of assembler-level
6282 addresses, and avoids misleading non-mangled source-level names.)
6284 Generalize ansi argument such that -1 means skip arglist totally.
6285 Removed global variable print_ansi_qualifiers (which made
6286 code non-reentrant), in favor of extra explicit arguments
6287 to internal routines.
6289 Add new helper function print_address_symbolic.
6290 Use find_pc_misc_function instead of find_pc_partial_function
6291 (since we want assembler-level symbols here).
6293 Print unknown function as just "f (...)", not "f (...) (...)".
6294 Use new fputs_demangled explicitly.
6296 Fixed a typing violation (problem: value.h cannot be imported
6297 without renaming many variable in this file).
6298 lookup_symbol: If no matching misc_func, look for a C++-mangled name.
6299 decode_line_1: Moved forward some never-reached code.
6300 Made decode_line_2 skip function prologues correctly.
6302 fputs_filtered should not demangle by default.
6303 Add new fputs_demangled to demangle on demand..
6305 Change value_struct_elt to use value_primitive_field (using recursive
6306 utility function search_struct_field). This allows foo.bar to work
6307 for multiple inheritance (so far only for data fields).
6308 Change check_field in the same way (recursive helper function
6309 to support multiple inheritance).
6310 (Note: there are more of these problems that I haven't fixed.
6311 Any code that says TYPE_BASECLASS (t, 1) is probably wrong.)
6312 value_of_this: 'this' symbol name is now just "this", note "$this".
6314 Don't print static members.
6315 Avoid printing "members of <type>" if there are none.
6316 Simplified type_print_derivation_info by merging duplicate code.
6317 Remove useless blank lines in type_print_base (ptype command).
6319 Added declaration of new routine value_primitive_field.
6321 Added value_primitive_field which is generalized version of
6322 value_field that can handle multiple inheritance (non-zero offsets etc).
6323 Re-implemented value_field to call value_primitive_field.
6325 Fri Aug 17 23:33:44 1990 John Gilmore (gnu at cygint)
6327 * infcmd.c -- insert else to avoid 'delete env' coredump when you
6328 delete the whole environment. Karl Berry reported the bug.
6329 * source.c - fix openp to avoid //'s in filenames, which
6330 trigger an Emacs bug causing it to not be able to find files
6331 when running gdb in a window.
6332 * dbxread.c - zap the #if 0 that botches the add-file code.
6333 It seems to work a lot better without all the code commented out.
6335 Fri Jul 20 16:58:46 1990 John Gilmore (gnu at cygnus.com)
6337 * Merge Tiemann's and Ted Goldstein's changes, detailed below,
6340 Tue Jul 17 19:34:33 1990 Ted Goldstein (tedg at golem)
6342 * Makefile - added a ${CFLAGS} to a couple of entries,
6343 added remote-sa.sparc.c
6344 * added remote.sa-sparc.c, a modification of remote.c
6345 which conducts a dialog directly with the SparcStation prom.
6346 * breakpoint.c, infrun.c, sparcdep.c added
6347 remote_insert_breakpoint(), and remote_remove_breakpoint()
6348 to breakpoint.c instead of directly writing breakpoint instructions.
6349 * sparcdep.c on remote_debugging,there is no need
6350 to remove signle step breakpoint instructions.
6351 * main.c added "-epoch" flag and "int epoch_interface" to main.c
6353 * printcmd.c - epoch interface sends lisp expressions to open up
6354 epoch windows on inspection.
6355 * valprint.c - added arrayprint, and addressprint and made adding
6356 format controls easier
6357 * wait.h added a couple of undef's because we were getting
6358 complaints about WSTOPSIG and WTERMSIG begin redefined.
6361 Wed Jul 4 05:27:51 1990 Michael Tiemann (tiemann at masham)
6363 * symtab.c (decode_line_1): Add support for handling method stubs
6364 in the type information.
6366 Tue Jul 3 09:39:18 1990 Michael Tiemann (tiemann at masham)
6368 * values.c (baseclass_addr): Run loop from INDEX+1 to
6369 N_BASECLASSES; otherwise, we can still get into a loop.
6370 @@ This should be restructured to use a cleaner search strategy.
6372 Sun Jul 1 12:28:51 1990 Michael Tiemann (tiemann at masham)
6374 * dbxread.c (define_symbol,read_type): Grok GNU C++'s new
6375 abbreviation "Tt" for tags which have the same name as their
6378 Fri Jun 29 01:03:46 1990 Michael Tiemann (tiemann at masham)
6380 * symtab.c (list_symbols): add ability to set breakpoints on all
6381 the functions which match a particular regular expression.
6383 Tue Jun 26 04:26:29 1990 Michael Tiemann (tiemann at masham)
6385 * cplus-dem.c (cplus_demangle): New parameter ANSI says whether we
6386 should print ANSI qualifiers (such as `const' and `volatile').
6387 All callers changed to call with ANSI == 1, except from
6388 `check_method_stub', which uses old-style syntax.
6390 * symseg.h (struct fn_field): Remove unneccessary `args' field.
