38 * symfile.c (compact_misc_function_vector): Handle empty vector.
39 (complain, clear_complaints, syms_from_objfile): Fix complaint
41 * xcoffexec.c: Change syms_from_objfile caller.
43 * sparc-xdep.c: Force tm-file as tm-sparc.h, to make it compile

47 Mon Dec 2 11:04:05 1991 Per Bothner (bothner at cygnus.com)
49 * mips-tdep.c (init_extra_frame_info): Float register
50 'i' has gdb-internal number 'FP0+i', not '32+i'.
51 * mipsread.c (new_symbol): Translate g++ special

120 * buildsym.c, symtab.c, values.c: Remove all references to
121 TYPE_MAIN_VARIANT and TYPE_NEXT_VARIANT.
123 * valops.c: Improve comments and indentation. Only call
124 check_stub_method when the stub flag is on.
125 * valprint.c: Fix or mark minor bugs and unportabilities.
127 * coffread.c (anonymous unions): Allocate a cplus structure.
129 * mipsread.c: Eliminate "template" types. Build new, real
130 types whenever we need them. Allocate cplus structures as needed.

132 (parse_type): Copy TYPE_TYPE_SPECIFIC when copying a real type
133 on top of a partial type.
135 Fri Nov 22 16:39:57 1991 John Gilmore (gnu at cygnus.com)

138 print a message if any of them fail.
139 (terminal_ours_1): Store result of ioctl's for debugging, but
140 don't print (the terminal isn't ours...).
142 * tm-tahoe.h (FRAME_ARGS_ADDRESS): No need to offset from frame
145 * m2-exp.y (MAX, MIN): Rename to MAX_FUNC, MIN_FUNC to avoid
146 conflicts with system header files.
148 Fri Nov 22 08:27:40 1991 John Gilmore (gnu at cygnus.com)
150 * Roll VERSION to 4.2.95.
152 * buildsym.c, coredep.c, mem-break.c, xcoffread.c: Put <stdio.h>
153 first, before defs.h.
154 * config/mh-i386sco: Override compiler to gcc, print warning.
155 * configure.in: Handle i386-none-aout rather than i386-aout-none.
156 * infptrace.c, language.h, utils.c: Lint.
157 * m2-exp.y: #undef MAX and MIN in case system includes set them.
158 * xm-tahoe.h: Set HOST_BYTE_ORDER. Include system versions of
159 {BIG,LITTLE}_ENDIAN and the INT_MAX family first, to avoid
160 redefinition warnings.
161 * defs.h: Reorder things so that the xm-file gets first crack
162 at #define's, followed by defs.h and then the tm-file.
163 * Makefile.in: Remove spaces after 'ignore exit code' - flags.
164 Late-model BSD 'make's don't cope with them.

168 * Makefile.in: Roll new files into various lists.
170 Thu Nov 21 18:26:11 1991 Fred Fish (fnf at cygnus.com)
172 * dwarfread.c (struct_type): Must initialize the c++ specific
173 portion of union types as well as struct types, since gdb attempts

200 Wed Nov 20 18:35:56 1991 John Gilmore (gnu at cygnus.com)
202 * Remove gdb/hp-include. Support for HP a.out oddities should be
203 in BFD, not in GDB. Move gdb/hp-include/a.out.h to include/a.out.hp.h.
205 * infptrace.c, tm-sun386.h: Cashier <a.out.gnu.h>, remove refs.
207 * configure.in, xconfig, tconfig, Makefile.in, doc/gdbint.texinfo:
208 Makefile fragments for various hosts and targets now come from
209 gdb/config/mh-* and gdb/config/mt-*. This is for consistency with
212 * rs6000-pinsn.c, rs6k-opcode.h: Clean up.
213 * rs6k-opcode.def: Delete.
215 Wed Nov 20 05:04:40 1991 Fred Fish (fnf at cygnus.com)
217 * dwarfread.c: Recognize obsolete form of AT_element_list
218 attribute still used by at least one AT&T compiler, and possibly
221 Tue Nov 19 07:53:55 1991 Fred Fish (fnf at cygnus.com)
223 * dwarfread.c (enum_type, struct_type): Ignore names invented by
224 helpful compilers for anonymous structs, unions, and enums.
226 * c-exp.y, m2-exp.y: Add defines for yymaxdepth, yy_yys, and
227 yy_yyv, so multiple parsers produced by SVR4 versions of yacc
228 can coexist in the same executable without collision.
230 * symtab.h: Add declaration for lookup_template_type() to kill
231 compiler warnings about conversions from int to pointer.
233 Mon Nov 18 17:45:18 1991 Fred Fish (fnf at cygnus.com)
235 * procfs.c: Move inclusion of defs.h to before param.h, as in
236 all the other source files that include both. This is required
237 to supply some typedefs that are used in files included by param.h.
239 * m68k-tdep.c (m68k_skip_prologue): Add generic m68k support for
240 skipping function prologues, ala the other cpu families (i386,
241 mips, m88k, etc). Add the ability to skip movm and fmovm
242 instructions in the prologues. Still needs support for profile
243 (-p compiled) prologue sequences (FIXME).
245 * tm-68k.h: Change SKIP_PROLOGUE macro to use the new generic
246 m68k prologue skipping function by default.
248 * tm-altos.h, tm-isi.h: Continue to use the old definition of

254 * blockframe.c: Remove tdesc-related code. Default
256 * infrun.c: Remove tdesc-related code.
257 * m88k-tdep.c (frame_chain_combine, init_frame_pc): Remove copies
258 of defaultable things.
259 * tm-m88k.h: New file, common to all Moto 88k target configs.
260 Derived from tm-delta88.h.
261 * tm-delta88.h: Use it.
262 * xm-m88k.h: Common file for 88K hosts. Remove obsolete stuff.

264 * tm-*.h: Remove FRAME_CHAIN_COMBINE macros, since all are
266 * coffread.c: Remove tdesc stuff.
267 * tconfig/delta88, tconfig/m88k: Remove tdesc stuff.
268 * xconfig/m88k: Rename tm-88k.h to tm-m88k.h.
270 Mon Nov 18 13:51:37 1991 Per Bothner (bothner at cygnus.com)
272 * source.c (open_source_file): If openp fails, try again
273 using just the base (non-directory) part of the filename.
274 This solves various annoying problems, such as when the
275 source was compiled with an absolute pathname - and the
276 source files have moved. Or if the source was compiled
277 using a relative pathname, it can be more convenient
278 to just specific the source directory to the dir command.
280 Mon Nov 18 00:04:41 1991 Fred Fish (fnf at cygnus.com)
282 * cplus-dem.c (munge_function_name): Add missing third arg to
283 instance of call to do_type().

291 * symtab.h (struct type): Moved C++-specific fields into new type
292 `struct cplus_struct_type'. Now takes 10% less memory. Many

295 TYPE_CPLUS_SPECIFIC unless TYPE is TYPE_CODE_STRUCT.
296 * buildsym.c (read_type): Allocate TYPE_CPLUS_SPECIFIC for
298 (read_struct_type): Ditto. Also, add comments about how we can
299 deduce TYPE_VPTR_FIELDNO from inheritance info and fieldname info.
300 * coffread.c (decode_base_type): Allocate TYPE_CPLUS_SPECIFIC for
302 (read_struct_type): Ditto.
303 * dwarfread.c (struct_type): Ditto.
305 * symtab.c (read_range_type): Don't set TYPE_MAIN_VARIANT.

321 * symfile.c: Add function compact_misc_function_vector() to
322 remove duplicate misc function vector entries. See comments
323 in source for why this is necessary/desirable.
325 * dwarfread.c: Add misc function type parameter to internal
326 record_misc_function(). Remove calls to init_misc_bunches()
327 and condense_misc_bunches(), these are now done in elfread.c.
329 * elfread.c: Add support for reading bfd canonical symbol tables
330 and generating misc function vector entries for global and
331 absolute symbols. Do calls to init_misc_bunches() and
332 condense_misc_bunches() where they will enclose all calls to
333 record_misc_function(), including those in dwarfread.c.
335 Thu Nov 14 17:02:11 1991 Roland H. Pesch (pesch at cygnus.com)
337 * doc/Makefile.in: new targets gdb.me, gdb.ms, gdb.mm
338 (roffable documentation).
339 * doc/gdb.texinfo: embedded hints (as comments) for better
340 texi2roff conversion.

356 Motorola 88000 port without tears, I mean without tdescs.
358 * m88k-tdep.c: Blow away all tdesc stuff.
359 Provide functions for all the frame-related macros in

362 from i960-tdep.c and adapt to the function prologues on the 88k.
363 (read_next_frame_reg): Borrow from mips-tdep.c.
364 FIXME: frame_locals_address should go away.
366 * tm-delta88.h: Dump all the tdesc stuff.
367 Macros for all frame-related stuff call fns of same name.
368 Remove duplicated definitions. FP_REGNUM becomes same as
371 * xm-88k.h: Eliminate lots of library dependencies, now handled
372 in libiberty. Eliminate KDB nonsupport.
374 * doc/gdbint.texinfo: Add rudiments on frames. FIXME, add more.

399 * buildsym.c, symtab.h: Remove TYPE_FLAGS_HAS{CON,DE}STRUCTOR
400 flags since they are no longer used.
402 Fixes to support C++ methods with functional parameters.
403 * c-exp.y (func_mod rule): Allow (and ignore) list of parameter
404 types in a function type.
405 * eval.c (parse_and_eval_type), value.h: New function,
406 parse_and_eval_type, is based on old code from check_stub_method.
407 But don't actually evaluate the cast, since that calls
408 value_cast(), whcih may fail. Just extract the type
409 from the parsed expression.
410 * values.c (check_stub_method): While looping through the
411 arguments, adjust depth *after* parameter has been handled.
412 Replace call and setup of parse_and_eval with new function

460 This includes a "struct objfile" that owns symtabs and psymtabs
461 that were read in from that binary file.
463 * symfile.h: Add struct objfile. Add pointer to the objfile
464 into the struct sym_fns.
465 Replace global `symfile' and `symfile_mtime' with
466 `symfile_objfile'. Add global object_files chain.

508 * coffread.c (end_symtab, read_coff_symtab): Take and use objfile arg.
509 (read_coff_symtab): Cleanup by freeing objfile, not all symtabs.
511 * mipsread.c (read_mips_symtab, parse_partial_symbols, parse_fdr,
512 new_psymtab, new_symtab): Take and use objfile arg.
514 * dwarfread.c (scan_compilation_units, start_psymtab,
515 process_dies, end_symtab, dwarf_build_psymtabs,
516 read_lexical_block_scope, read_func_scope, read_file_scope): Take
517 and use objfile argument.
518 (psymtab_to_symtab_1, read_ofile_symtab): Don't take or use file
519 descriptor. Use BFD internal functions instead.
520 (end_symtab): Call global allocate_symtab.
522 * elfread.c, target.c: Minor changes to accommodate objfiles.
523 * symtab.h: partial_symbol_table has no symfile_name member now.
524 (fn_fieldlists voffset): avoid non-int bitfield.
525 (struct symtab): Add objfile * and objfile_chain * of symtabs.
526 (struct partial_symtab): Add objfile * and objfile_chain * of
527 psymtabs. Remove symfile_name.
529 * symmisc.c: Lose free_all_symtabs, free_all_psymtabs.
530 (printsyms_command): Rename from print_symtabs. Add selective
531 listing if 2nd argument given. Print objfile info.
532 (printpsyms_command): Rename from print_partial_symtabs. Ditto all.
533 (printobjfiles_command): New; prints objfiles lists, and checks
534 for consistency of symtab, psymtab, and objfile lists.
536 * symfile.h, symfile.c, symtab.h: Lint
538 Fri Nov 8 23:38:48 1991 John Gilmore (gnu at cygnus.com)
540 * command.c: Include param.h.
541 * defs.h (warning_setup, warning): Declare.
542 * expprint.c (print_subexp, UNOP_MEMVAL case): Lint.
543 * inflow.c (new_tty): Use USE_O_NOCTTY #define.
544 * language.c, printcmd.c (print_scalar_formatted), signame.c,
547 Thu Nov 7 18:26:15 1991 Steve Chamberlain (sac at rtl.cygnus.com)
549 * Makefile.in: link with libiberty after libreadline, since
550 readline might want something in libiberty.
551 * m88k-xdep.c: Fixed the register offsets in the ptrace_user
552 struct for BCS 88k machines.
553 * xm-m88k.h: don't define USIZE if already defined.
554 * configure.in: Added delta88 target.
556 Thu Nov 7 04:51:19 1991 John Gilmore (gnu at cygnus.com)
558 * am29k-pinsn.c, am29k-opcode.h: Fix decoding of mtacc, dmac, fmac.
560 * tm-*.h: Remove READ_DBX_FORMAT, COFF_FORMAT, and
561 READ_MIPS_FORMAT, which have been unused since BFD. Still
562 remaining is COFF_NO_LONG_FILE_NAMES.
563 * tm-sun3.h, tm-altos.h: Remove detritus accidentally left from
564 function calling code moved to m68k-tdep.c.
566 Wed Nov 6 17:21:59 1991 John Gilmore (gnu at cygnus.com)
568 * coffread.c: Eliminate c_nsyms in favor of c_naux.
569 Complain if no auxents on .bf and .ef FCN symbols, and assume
570 lots of line numbers.
571 (init_linenos, enter_linenos): Use a sentinel at the end of the
572 read-in linenos, to make for a fast, safe loop-end test.
574 Wed Nov 6 02:54:08 1991 Steve Chamberlain (sac at cygnus.com)
576 * coffread.c (read_coff_symtab): coffread used to rely on the
577 x_sym.x_misc.x_lnsz.x_lnno field giving the # of linnos in a
578 function. Two of the formats I'm using (29k and 88k) don't seem to
579 set it. Ths patch to fcn_last_line and (enter_linenos) is an
580 attempt to use the actual size of the linno table in the file to set
581 the number of linenos to process.
583 Tue Nov 5 22:47:46 1991 Steve Chamberlain (sac at cygnus.com)
585 * Makefile.in: put a - infront of the mv y.tab.c c-exp.tab.c and
586 mv y.tab.c m2-exp.tab.c, so that if bison is used, and the files
587 are created in place, so the mv fails, then the make continues.
589 Tue Nov 5 16:47:47 1991 Per Bothner (bothner at cygnus.com)
591 Add C++ as a separate language.
592 * defs.h (enum language): Add language_cplus.
593 * dwarfread.c (end_symtab): Support language_cplus.
594 * c-exp.y: Add new struct language_defn cplus_language_defn.
595 Don't set c to be the default language (see main.c).
596 * c-exp.y (yylex): Only look for field of this if
597 language is C++. (First difference from C!)
598 * language.c: Add case branches for C++ (currently, all
599 the same as C). Also, add c++ to "usage" note for "set lang".
600 * valprint.c (typedef_print). Add case branches for C++.
601 * main.c (main): New way to set initial language: Look at
602 file extension of psymtab containing main(). (Same as we
603 do for symtabs, but avoid loading the symtab yet.)
604 * symtab.c: New routine find_main_psymtab(), used by main()
605 to set initial language.
606 * symfile.c (allocate_symtab): Move code for mapping file
607 extensions-> languages to new deduce_language_from_filename().
609 Fix a C++ problem when looking for methods in super-classes.
610 There was confusion between base and derived types.
611 * valops.c (value_fn_field): Change function interface.
612 * values.c: Use new value_fn_field interface.
614 Mon Nov 4 10:49:33 1991 Per Bothner (bothner at cygnus.com)
616 * infrun.c: Fixed typo in comment.
617 * utils.c: All the v*fprintf emulation is now in libiberty,
618 so we can get rid of some junk.
619 * xm-sun3os4.h, xm-sun4os4.h, xconfig/decstation, xconfig/i386sco,
620 xconfig/sun3os4, xconfig/sun4os4: Don`t need HAVE_STRSTR any more.
621 * m68k-pinsn.c (print_insn_arg): Support BB/BW/BL
622 type operands, as used by branch instructions.
623 * gmalloc.c: Fix prototype of memcpy.
624 * elfread.c: Comment out register_addr, since it conflicts
625 with the one in coredep.c.
626 * buildsym.h: Remove extern declarations of two functions
627 that are really static in buildsym.c.
628 * tm-mips.h: Add symbolic names for more registers.
629 * mips-xdep.c (store_inferior_registers): Use new register names.
630 * xm-mips.h: Simplify REGISTER_U_ADDR, since it is now
631 only used for core files, not ptrace. Therefore,
632 the KERNEL_U_ADDR hack is no longer needed.
633 The mapping to ptrace number is now in in mips-xdep.c.
634 * mips-xdep.c: Define REGISTER_PTRACE_ADDR (using the
635 mapping from the old REGISTER_U_ADDR), and use it
636 in {fetch,store}_inferior_registers.
637 * mipsread.c: Rename #include ecoff.h to new name coff-mips.h.
638 * mips-tdep.c (mips_push_dummy_frame, mips_pop_frame):
639 Save/restore FP regs correctly (?).
640 * dbxread.c: Remove duplicate define_symbol and type_synonym_name
641 (these had been previously moved to buildsym.c).
642 Hence, define_symbol becomes extern instead of static.
643 * buildsym.c (read_struct_type): Comment out bogus handling
644 of C++ operator methods. Minor hacking of reading of class
645 contexts. Make define_symbol non-static, so dbxread.c can call it.
647 Fri Nov 1 11:05:47 1991 John Gilmore (gnu at cygnus.com)
649 * mipsread.c (read_mips_symtab, read_the_mips_symtab): Use real
650 filename with error messages.
651 * stack.c (frame_select_command): Rename to select_frame_command
652 to avoid "fr" and "fra" having nonunique completions.
653 * symfile.c (sort_symtab_syms): Ignore sort of zero symtab *.
654 (symfile_init): Print file format name when unable to handle it.
655 (free_named_symtabs): Use BLOCKVECTOR rather than obsolete BLOCKLIST.
656 * symmisc.c (free_symtab): Only free linetable if nonzero.
657 * symtab.h: Remove obsolete BLOCKLIST macros.
659 Thu Oct 31 18:12:43 1991 Stu Grossman (grossman at cygnus.com)
661 * infrun.c (wait_for_inferior): another stepi/nexti fix. Ensure
662 that stop_step is 1 at bottom of main loop. I don't know why this
663 needs to be done, but it helps me sleep better at night.
665 Sun Oct 27 18:18:39 1991 Stu Grossman (grossman at cygnus.com)
667 * main.c (initialize_history): Read history after reading all
670 Sun Oct 27 14:09:25 1991 John Gilmore (gnu at cygnus.com)
672 * buildsym.c: Break out initial malloc sizes.
673 (record_line): Record directly in a subfile. Alloc on demand.
674 (compare_line_numbers): Add from xcoffread.c.
675 (end_symtab): New params say whether to sort pendings and
676 linetable. Patch block stabs if defined. Shrink linetable before
677 allocating the symtab.
678 * buildsym.h: Delete line_vector* and prev_line_number. Add
679 global_stabs and file_stabs for xcoffread.
680 * dbxread.c (start_subfile): Move to buildsym. Change above calls.
681 * symtab.h: LINETABLE(symtab) can now be null. Zap LINELIST.
682 * symmisc.c, symtab.c: Cope with null LINETABLEs.
684 * blockframe.c: Pass fromleaf to INIT_EXTRA_FRAME_INFO.
685 * tm-29k.h, tm-88k.h, tm-i960.h, tm-irix3.h, tm-mips.h, tm-pyr.h,
686 tm-sparc.h: Accept fromleaf parameter.
687 * c-exp.y (yyerror): Pass error message if given.
688 * configure.in: Add rs6000 host and target.
689 * inflow.c (new_tty): O_NOCTTY kludge for RS/6000.
690 * symfile.h (entry_point): Add.
692 Sat Oct 26 00:16:32 1991 John Gilmore (gnu at cygus.com)
694 * buildsym.c: New file. Breaks out symbol-table-building routines
695 from dbxread.c, so they can be shared with xcoffread.c.
696 * buildsym.h: New file. Declarations for buildsym.c users.
697 * dbxread.c: Remove large chunks into buildsym.c.
698 * Makefile.in: Add buildsym.c and buildsym.h.
700 * symfile.c (syms_from_bfd): New routine.
701 (add_symbol_file): Call it to do the real work.
702 (syms_from_bfd): Initialize entry_point before calling symfile_init.
703 * symtab.h, symfile.c, coffread.c, mipsread.c, dwarfread.c:
704 Avoid declaring or setting entry_point (symfile.h & symfile.c cope).
706 Fri Oct 25 10:58:16 1991 Mark Eichin (eichin at cygnus.com)
708 * cplus-dem.c (cplus-demangle): added support for templates, static
709 data, and the new (correct) mangling for destructors.
711 * dwarfread.c: (dwarfwarn): created a varargs version of
712 dwarfwarn, for non __STDC__ compilers.
714 * c-exp.y: (yylex): added match for "template" token.
715 (typebase): added TEMPLATE name '<' type '>' clause, for explicit
716 specification of template types.
718 * symtab.c: (lookup_template_type): new function for finding
719 templates in symbol table.
720 (type_name_no_tag): changed to explicitly check for s/u/e at the
721 beginning of the symbol - if it is a template, none of these will
722 be there (but the name will still contain spaces.)
724 Fri Oct 25 18:59:32 1991 Per Bothner (bothner at cygnus.com)
726 Various fixes to improve g++ debugging.
727 * symtab.h: Add is_const and is_volatile flags for each method.
728 These are bit fields - take their space from voffset,
729 which shrinks to 30 bits. Since voffset is now a bitfield,
730 make it unsigned for portability. This changes its interpretation
731 slightly: Static methods now have voffset 1 instead of -1,
732 and virtual offsets start at 2, not 1.
733 * symtab.c: Renamed gdb_mangle_typename to gdb_mangle_name,
734 since it now returns an entire magled method name, not just
735 the type part. This avoids some duplication.
736 It also allows us to correctly mangle const and volatile
737 methods (using the new is_const and is_volatile bit fields
739 * valprint.c (type_print_base), values.c (check_stub_method):
740 Simplify by using new gdb_mangle_name.
741 * values.c (value_headof): Fix to correctly handle single
742 inheritance (actually two fixes, either of which suffices).
743 * dbxread.c (read_struct_type): Handle const and volatile
745 * dbxread.c (read_struct_type): Yet one more place where
746 we must handle '\\' continuations.
747 * valprint.c (vtbl_ptr_name): Add final '\0'.
749 Fri Oct 25 16:06:38 1991 Stu Grossman (grossman at cygnus.com)
751 * tm-sparc.h, tm-68k.h (EXTRACT_RETURN_VALUE): fix output of
752 short return values for sparc and 68k. Patch from Paul Eggert.
754 * coffread.c, coredep.c, i386-xdep.c: install patches for
755 SysV/386 3.2 from Mauro DePalma.
757 Fri Oct 25 02:02:13 1991 John Gilmore (gnu at cygnus.com)
759 * core.c (core_file_info), exec.c (exec_file_info): Print file
760 type. Use printf_filtered.
762 * valops.c (value_fetch_lazy): Avoid 0-length fetches.
764 Thu Oct 24 23:06:40 1991 Fred Fish (fnf at cygnus.com)
766 * dwarfread.c: Add casts to remove compiler warnings.
768 * tm-3b1.h, tm-68k.h, tm-altos.h, tm-amix.h, tm-hp300bsd.h,
769 tm-hp300hpux.h, tm-isi.h, tm-news.h, tm-pn.h, tm-sun2.h,
770 tm-sun3.h: Remove locally duplicated code for calling functions
771 in the inferior. The only differences were in the specific trap
772 vectors used and whether or not an fpu was present. These are
773 now handled by appropriate definitions of BPT_VECTOR and
774 HAVE_68881 respectively. Other minor obvious cleanups.
776 * valops.c: Correct a minor misspelling.
778 * utils.c: Remove local BSD/USG hacks that are now in libiberty.
780 * dwarfread.c: Remove prototype for dwarfwarn. Does not work
783 Thu Oct 24 09:33:44 1991 John Gilmore (gnu at cygnus.com)
785 * stack.c (frame_command): Always print. Use new
786 frame_select_command to select a frame without printing.
788 * dwarfread.c: Use <varargs.h>, since <stdarg.h> is not portable.
790 Thu Oct 24 01:32:51 1991 Fred Fish (fnf at cygnus.com)
792 * dwarfread.c: New file for DWARF debugging format support.
794 * elfread.c: New file for ELF object file format support.
796 * procfs.c: New file for SVR4 /proc (process file system) support.
798 * tm-amix.h, xm-amix.h, tconfig/amix, xconfig/amix: New files for
801 * xm-svr4.h, tm-svr4.h: New files for SVR4 support.
803 * xm-m68k.h: New file for host machines with m68k cpu.
805 * Makefile.in: Add elfread.c and dwarfread.c to SFILES_MAINDIR.
806 Add elfread.o and dwarfread.o to OBS.
808 * symfile.h: Add "elf" to list of supported formats in comment.
810 * c-exp.y, defs.h, symtab.h, valprint.c: Add three new builtin
811 types to gdb, builtin_type_long_double, builtin_type_complex, and
812 builtin_type_double_complex. Add and use new TARGET_SHORT_BIT,
813 TARGET_INT_BIT, TARGET_LONG_BIT, TARGET_FLOAT_BIT,
814 TARGET_DOUBLE_BIT, TARGET_LONG_DOUBLE_BIT, TARGET_COMPLEX_BIT, and
815 TARGET_DOUBLE_COMPLEX_BIT, as the sizes in bits of the indicated
816 types on the target machine (ala the existing TARGET_LONG_LONG_BIT).
818 * infrun.c: When using SVR4 /proc interface instead of ptrace(),
819 call proc_set_exec_trap() to setup child to stop at first instruction.
821 * inftarg.c: When using SVR4 /proc interface, call proc_wait()
824 * m68k-tdep.c: Add new routines supply_gregset(), fill_gregset(),
825 supply_fpregset(), and fill_fpregset(), which are machine
826 dependent support routines for SVR4 /proc interface.
828 * utils.c: Add warning_setup() and warning(). Warning() behaves
829 the same as error() except that it returns normally rather than
830 jumping back to command level. Modules that don't want to call
831 warning() for some reason, but want to produce their own warnings,
832 can call warning_setup() to ensure compatibility with the way
833 warning() and error() deal with the terminal.
835 * symtab.c: Make internal errors produce more useful messages.
837 * tm-68k.h: Move code that is duplicated in almost every single
838 m68k based machine's configuration files to this common file.
839 Duplications in the configuration files still need to be removed
842 * infrun.c (child_create_inferior): System V versions must call
843 setpgrp() with no arguments, to comply with prototyping typically
846 * munch: Add support for SVR4 style nm output.
848 * dbxread.c, mipsread.c symmisc.c, symtab.c: Remove the object
849 file specific fields from the partial symbol table structure and
850 replace them with a pointer to private data for each different
851 flavor of object file reader to initialize appropriately.
853 Wed Oct 23 09:38:20 1991 John Gilmore (gnu at cygnus.com)
855 * xconfig/sun[34]os4: Add note about strstr botch on sunos4.0.3c
858 * mipsread.c (fixup_undef_type): New function. If a struct /
859 union / enum is defined in a header file but nowhere else used,
860 (by typedefing, pointer referencing or declaration) the mipsread code
861 builds the complete tree for the structure but leaves its code as
862 TYPE_CODE_UNDEF as it doesn't know what kind of aggregate it is.
863 Guess its type based on the details of the members.
865 Tue Oct 22 18:04:32 1991 Stu Grossman (grossman at cygnus.com)
867 * infrun.c (wait_for_inferior): Check return value from
870 Mon Oct 21 17:47:03 1991 Stu Grossman (grossman at cygnus.com)
872 * infrun.c (wait_for_inferior): fix stepi/nexti that was broken
873 by my last edit to this routine.
875 Mon Oct 21 14:27:43 1991 John Gilmore (gnu at cygnus.com)
877 * tm-sun3.h (FIX_CALL_DUMMY): problem with cross debugging.
878 FIX_CALL_DUMMY does unaligned accesses and/or forgets to byte swap
879 the values before putting them into the dummy code. (From Peter
882 Mon Oct 21 10:04:39 1991 Steve Chamberlain (steve at rtl.cygnus.com)
884 * configure.in: added ebmon target.
886 Wed Oct 16 22:49:58 1991 John Gilmore (gnu at cygnus.com)
890 * Makefile.in: Roll VERSION to 4.2.
891 * README, TODO, WHATS.NEW: Update.
893 * core.c (core_open): Improve error message for bad file.
894 Pass .reg virtual memory address to fetch_core_registers to help
895 it find the registers in the core-file header.
896 * coredep.c (fetch_core_registers): Take new argument, use it,
897 and pass it to register_addr to locate the block of registers.
898 * xm-mips.h: Update KERNEL_U_ADDR for new scheme. Cleanup a bit.
900 * dbxread.c (read_dbx_symtab, process_one_symbol): Handle
901 Sequent N_FN_SEQ like everybody else's N_FN.
903 * main.c: Circumvent SCO cc bug with #if !!defined(USG).
904 * tm-i386v.h: #endif guck.
905 * xconfig/i386*: Remove -Dgetpagesize()=4096 kludge.
906 * xconfig/i386sco: Add HAVE_STRSTR to avoid ANSI bdeath.
907 * xconfig/tahoe: Add REGEX, which seems to be missing.
909 * coredep.c: Add <sys/types.h> for SCOnix.
910 * dbxread.c (read_dbx_symntab): Avoid coredump on malformed file.
911 * printcmd.c (print_formatted): Flush output before disassembly.
913 Tue Oct 15 20:12:32 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
915 * doc/refcard.tex (sec "Working Files"): consistent metavars and
916 other improvements, due to comments by François Pinard
917 (pinard@iro.umontreal.ca)
919 * doc/gdb.texinfo (appendix "Installing GDB"): changes in
920 configure, and improvenets related to Pinard's refcard comments
922 Tue Oct 15 08:45:12 1991 John Gilmore (gnu at cygnus.com)
924 Changes from Fred Fish:
925 * tm-68k.h (FPI_REGNUM): Add.

947 (nodes Continuing and Stepping; Memory; Targets) clarifications
950 Fri Oct 11 23:27:06 1991 John Gilmore (gnu at cygnus.com)
952 * tm-{irix3,mips,nindy960,pn,symmetry,vx960}.h: Move
953 REGISTER_U_ADDR to corresponding xm- file. Sugg. by Peter Schauer.
955 * symmisc.c (print_partial_symtabs): Add printpsyms debug cmd.
957 * m68k-tdep.c (m68k_push_dummy_frame, m68k_pop_frame): Add
958 generic routines for calling inferior functions.
960 * blockframe.c (inside_main_scope, inside_entry_scope): New.
962 * copying.awk: Filter formfeeds out of copying & warrantee.
963 Make them available as `show copying' and `show warrantee' also.
964 * main.c (print_gnu_advertisement): Advt `show' commands.
966 Thu Oct 10 17:25:47 1991 John Gilmore (gnu at cygnus.com)

975 This avoids coredumps under `set print object on' in value_headof
976 (called erroneously by value_from_vtable_info) for `p &struct'
977 or `p *struct'. From Peter Schauer.
979 Mon Oct 7 00:06:52 1991 John Gilmore (gnu at cygnus.com)
981 * Makefile.in: Roll version to 4.1.2.
982 * dbxread.c: Use aout64.h, not a.out.gnu.h. Get external symbol entry
983 size from BFD (but, FIXME, we don't yet read external nlists's and
984 convert them to internal nlists's before handling them -- we still
985 assume they have the same size and alignment.) Use SET_NAMESTRING
987 * exec.c (exec_file_command): Move dead coff-encapsulation code
989 * m88k-tdep.c, m88k-xdep.c: Remove encap test and #inc <a.out.h>.
991 Fri Oct 4 22:30:06 1991 John Gilmore (gnu at cygnus.com)
993 * configure.in, tm-i386v.h, xm-i386v.h: Intel 386 Mach host port.
994 * xm-i386mach.h, mach386-xdep.c, xconfig/i386mach: New files.
996 Fri Oct 4 17:04:31 1991 Per Bothner (bothner at cygnus.com)
998 More patches from Peter Schauer <pes@regent.e-technik.tu-muenchen.de>:
999 * mips-xdep.c (store_inferior_registers): Don't try to
1000 write the (pseudo) FP.
1001 * mipsread.c (parse_partial_symbols): Improved algorithm for
1002 setting pst->texthigh.
1004 Fri Oct 4 16:47:32 1991 Roland H. Pesch (pesch at cygnus.com)
1006 * doc/Makefile: make TEXINPUTS include . everywhere
1008 Fri Oct 4 00:35:56 1991 John Gilmore (gnu at cygnus.com)
1010 * coffread.c, dbxread.c, symfile.c, symmisc.c, symtab.h: Remove
1011 vestiges of typevectors, which were for symsegs and are no longer
1012 used. (From a question by Eliot Dresselhaus
1013 <dresselh@RFT30.nas.nasa.gov>).
1015 Thu Oct 3 09:33:26 1991 John Gilmore (gnu at cygnus.com)
1017 * dbxread.c, coffread.c: static-ize functions that were
1018 gratuitiously external. (From Fred Fish.)
1020 * c-exp.y: sym->class to SYMBOL_CLASS (sym).
1022 * dbxread.c (dbx_lookup_type): Keep doubling size of typevector
1023 until it is large enough.
1025 * dbxread.c (read_type): Handle error case slightly better.
1026 Make complaint message not C++-specific.
1028 Wed Oct 2 17:21:07 1991 Stu Grossman (grossman at cygnus.com)
1030 * infrun.c (wait_for_inferior): Fix step/next so that you only
1031 stop at the beginning of a new line. This fixes various problems
1032 with for loops, nested if-else's and switch statements.
1034 Tue Oct 1 06:33:55 1991 John Gilmore (gnu at cygnus.com)
1036 * symtab.c (lookup_symtab_1, lookup_symbol): "fatal" errors
1037 between symtabs and psymtabs become ordinary error()s.
1039 * dbxread.c (read_dbx_symtab): Relocate end_of_text_addr
1040 properly, making "end pc" correct in shared lib psymtabs.
1041 (From Guy Harris <guy@auspex.com>.)
1043 Mon Sep 30 13:15:31 1991 John Gilmore (gnu at cygnus.com)
1045 * dbxread.c: Enable, but soften, const_vol_complaint.
1046 (read_dbx_symtab): N_STSYM and N_LCSYM define static vars.
1047 Ditto Gould N_NBSTS and N_NBLCS. Also, all types in the psymtab
1048 should be file-scope, not global.
1049 (read_struct_type): Remove ancient multiple-inheritance warning.
1050 (read_range_type): Check base type, complain & patch if undefined.
1051 * stack.c (frame_info): Demangle the function name in `info stack'.
1052 (From Peter Schauer)
1054 Sat Sep 28 10:02:33 1991 John Gilmore (gnu at cygnus.com)
1056 * eval.c (evaluate_subexp_for_address): Don't use
1057 TYPE_POINTER_TYPE directly (it might be zero if this type has
1058 never had a pointer created before); use lookup_pointer_type.
1059 * symtab.c (lookup_method_type): Arguments were swapped in all
1060 callers, so fix it here. I'm amazed this worked at all!
1062 Fri Sep 27 18:09:31 1991 John Gilmore (gnu at cygnus.com)
1064 * c-exp.y, m2-exp.y: Define more yysymbols that happen to be
1065 "bss" rather than "data" symbols, but which still conflict.
1068 * coffread.c (coff_symfile_read): Use xmalloc, not malloc.
1069 * core.c (core_files_info): Shorten output.
1070 * exec.c (exec_files_info): Ditto.
1071 (build_section_table): Ignore zero-length sections.
1072 * language.c, printcmd.c: Lint.
1073 * language.h (get_frame_language): Declare.
1074 * saber.suppress: update.
1075 * stack.c (find_relative_frame): Remove complex code that was
1076 #if 0'd, stick with simple code. Lint.
1077 * saber.suppress: Update a bit.
1078 * symfile.c (add_symbol_file_command): Add "?" to question.
1079 * utils.c (parse_escape): Avoid \a due to bdead compilers.
1080 * value.h: Declare typedef_print.
1082 * valprint.c (val_print, type_print_base): TYPE_CODE_RANGE less
1085 * nindy-tdep.c (nindy_frame_chain_valid): Use lookup_misc_func.
1086 (Reported by Mark Peek <mark@imagen.com>.)
1088 * solib.c (solib_map_sections): Relocate all sections, even
1089 though only the text section's size is tracked. Mark ld_text
1090 for eventual elimination as we generalize to N sections.
1092 * infrun.c (wait_for_inferior): Don't check if the PC is in a
1093 call_dummy if we were stopped by a random signal that is being
1094 passed to the program. This produced wierd results when calling
1095 functions in the inferior and signals (e.g. SIGALRM) were in use.
1097 Tue Sep 24 18:05:30 1991 John Gilmore (gnu at cygnus.com)
1099 * infrun.c (IN_SIGTRAMP): Not parenthesized properly.
1100 Bugfix from Paul Eggert <eggert@twinsun.com>.
1101 * tm-ultra3.h (IN_SIGTRAMP): Ditto.
1102 * valprint.c (print_floating): Print 9 digits for IEEE floats.
1105 Mon Sep 23 15:50:07 1991 John Gilmore (gnu at cygnus.com)

1111 Fri Sep 20 16:10:52 1991 John Gilmore (gnu at cygnus.com)
1115 * Makefile.in (VERSION): Set to 4.1.
1116 * language.c (set_language_command): Print useful help message,
1117 and restore the language string after giving help.
1118 * valprint.c (typedef_print): Print typedef in C or M2.
1119 * symtab.c (list_symbols): Use it.
1120 * main.c (main): Avoid any output before (gdb) prompt when -q.
1121 * language.c (set_language_command): Handle errors by restoring
1122 the language string to its current state (fix from A. Beers).
1123 * doc/gdbint.texinfo: Roll in information from README. Rearrange
1124 "how to install" and "how to print the doc" stuff so it drops
1126 * configure.in: Rename rtpc CPU to romp to match config.sub.
1127 * README, WHATS.NEW, TODO: Update for gdb-4.1.
1129 Fri Sep 20 17:39:14 1991 Roland H. Pesch (pesch at cygnus.com)
1131 * doc/gdb.texinfo: Updates from ChangeLog. set/show write,
1132 autoloading shared libs, copyright etc on GDB startup, clean up $_
1133 and $__ index refs, set/show listsize and related updates to list
1134 cmd. New host/target configs.
1136 Fri Sep 20 15:46:00 1991 Roland H. Pesch (pesch at cygnus.com)
1138 * doc/Makefile: generate aux version-no file doc/gdbVN.m4
1139 from main Makefile.in version definition
1140 doc/gdb.texinfo: use version recorded in doc/gdbVN.m4 for current
1142 Makefile.in (setup-to-dist): generate doc/gdbVN.m4
1144 * doc/gdb.texinfo: merge new language-switching and lang-specific
1147 Fri Sep 20 15:00:57 1991 Per Bothner (bothner at cygnus.com)
1149 * mcheck.c: Add __ONEFILE kludge to allow compilation by non-ANSI
1150 compilers (which may lack stddef.h).
1152 Fri Sep 20 13:29:42 1991 John Gilmore (gnu at cygnus.com)
1154 * dbxread.c (read_dbx_symtab, process_one_symbol): N_FN and
1155 N_WARNING are the same except for the N_EXT bit, so just use their
1156 values alone, rather than OR-ing them with N_EXT.
1158 Fri Sep 20 12:27:55 1991 Stu Grossman (grossman at cygnus.com)
1160 * mipsread.c (parse_lines): Deal with negative extended line
1163 * c-exp.y, m2-exp.y: #define yyerrflag and yynerrs to avoid
1164 global symbol conflicts.
1166 Fri Sep 20 02:28:15 1991 John Gilmore (gnu at cygnus.com)
1168 * .gdbinit: Move 'set complaints' to top, so it runs even in
1169 case we aren't debugging GDB.
1170 * language.c (_initialize_language): Fix type check and range
1171 check documentation strings.
1172 * utils.c (!HAVE_VPRINTF): Define vfprintf as a function, so
1173 language.c can use it. (Though language.c should really not be
1174 handling warnings/errors the way it does, FIXME.)
1175 * symtab.c (lookup_primitive_type): const lint.
1177 Bugfix from Peter Schauer:
1178 * source.c (lines_to_list): Make signed, to avoid comparison
1179 going unsigned and complaining that -3 is too high for 21 lines.
1180 * stack.c (lines_to_list): Ditto.
1182 Thu Sep 19 23:33:41 1991 John Gilmore (gnu at cygnus.com)
1184 * Makefile.in (HFILES): Add minimon.h.
1185 (VERSION): Roll version number to 4.0.95.
1186 (gdb.tar.Z, make-proto-gdb.dir, setup-to-dist, gdb-XXX.tar.Z):
1187 New rules for building distributions. Normal distribution
1188 is built by doing `make -f Makefile.in gdb.tar.Z' in the directory
1189 one level up from here; it calls make-proto-gdb.dir to build a
1190 directory `proto-gdb' which is an image of the release. The old
1191 `gdb.tar.Z' rule still works too.
1192 * config.sub, configure: Roll in latest from ..
1194 Thu Sep 19 17:41:24 1991 Roland H. Pesch (pesch at cygnus.com)
1196 * doc/gdbint.texinfo: Reorder contents; reorganize new-host,
1197 new-target, and new-config chapters; fix minor typos; come closer
1198 to usual GNU markup conventions for @file @samp @code @var.
1200 Thu Sep 19 17:04:12 1991 Per Bothner (bothner at cygnus.com)
1202 Patches from Peter Schauer <pes@regent.e-technik.tu-muenchen.de>:
1203 * mipsread.c (parse_partial_symbols): Enter the name of all
1204 structs/unions... into the psymtab so we can access them if the
1205 symtab is not read in.
1206 * mips-tdep.c: Remove some unneeded #includes.
1207 * xconfig/dec3100: Add HAVE_STRSTR.
1209 Thu Sep 19 15:14:23 1991 John Gilmore (gnu at cygnus.com)
1211 * Makefile.in: Circumvent Sun Make bug on *-exp.tab.o.
1212 * c-exp.y, m2-exp.y: Lint.
1213 * m2-exp.y: Avoid using yytname[] which is a Bison-ism.
1214 * valprint.c (val_print_fields): Check for stub type.
1215 * mipsread.c (_initialize_mipsread): Avoid using
1216 builtin_type_void at initialize time.
1217 (mipscoff_symfile_read): use it now.
1219 Wed Sep 18 15:55:51 1991 John Gilmore (gnu at cygnus.com)
1221 Merge multiple-language support, and partial Modula-2 support,
1222 from Andrew Beers <beers@cs.buffalo.edu>.
1224 * i387-tdep.c: New file, consolidates most 80387 support,
1225 and eliminates host dependency on double<->extended conversions.
1226 * i386-xdep.c, symm-xdep.c: Remove most 387 support.
1227 * xconfig/i386{sco,v,v-g,v32,v32-g}: Now need i387-tdep.o.
1229 * symfile.c (allocate_symtab): New fn, consolidates the work
1230 of allocating and initializing a new struct symtab. Set the
1231 language of the symtab based on its filename extension.
1232 * symfile.h: Declare it.
1233 * mipsread.c (new_symtab): Use it. Minor formatting changes.
1234 * dbxread.c (end_symtab): Use it.
1236 * mipsread.c (parse_symbol, case stParam and stProc): Add #if 0'd
1237 code for saving types of parameters with each function definition.
1238 * dbxread.c (define_symbol, function and parameter cases): Ditto.
1239 (read_dbx_symtab, case N_DEFD): Ignore.
1240 (read_enum_type): Recognize FALSE/TRUE enum as Modula-2 BOOLEAN.
1241 (read_range_type): Rename MAX_OF_TYPE to MAX_OF_C_TYPE, etc.
1242 #if 0 out its uses, though, since they set a dead value.
1243 * coffread.c (end_symtab): Use allocate_symtab.
1244 (process_coff_symbol): #if 0'd for functions and params as above.
1245 (read_enum_type): Recognize Modula-2 BOOLEAN.
1246 * symtab.c (add_param_to_type): #if 0'd function to add a
1247 parameter type to a function type's field list.
1249 * defs.h (local_hex_format, local_hex_string, *_custom): Add.
1250 * i386-xdep.c, pyr-tdep.c, pyr-xdep.c, remote-vx.c, solib.c,
1251 source.c, symfile.c, dbxread.c, breakpoint.c, core.c, exec.c,
1252 i387-tdep.c, infcmd.c, mips-tdep.c, stack.c, printcmd.c: Output
1253 hex with local_hex_string for Modula-2 support.
1255 * breakpoint.c (breakpoint_cond_eval): Use new value_true to test
1256 breakpoint condition language-independently.
1258 * parse.c: New file with the common code remains of expread.y.
1259 * parser-defs.h: New file with common declarations from expread.y.
1260 * c-exp.y: New file with the C parser from expread.y, and other

1263 * expread.y, expread.tab.c: Remove.
1264 * breakpoint.c, eval.c, printcmd.c, expression.h: Use
1265 parse_expression and parse_exp_1 rather than parse_c_expression

1289 * stack.c (frame_info): Print language of stack frame.
1290 (select_frame): Also select language, if in auto-mode.

1318 Tue Sep 17 08:37:41 1991 John Gilmore (gnu at cygint.cygnus.com)
1320 Add Andrew Beers' changes for Modula-2 support. His ChangeLog
1321 entries are enclosed herein. Not all of these changes
1322 have been merged into the master GDB sources -- check the
1323 ChangeLog above here for the merge log.
1325 Mon Jun 3 17:05:45 EDT 1991
1327 m2-exp.y Created. Tested outside of GDB for a few days. Proper
1328 operators were added, C specific operators and tokens
1329 removed. yylex() revamped to some extent. Still things
1330 missing from the grammar, such as sets.
1331 Tested for two weeks in GDB v3.5.
1333 Tue Jun 11 17:23:48 EDT 1991
1335 m2-exp.y Added boolean constants TRUE and FALSE to the grammar
1336 so they are built-in. Sort of a hack.
1338 Fri Jun 14 12:53:51 EDT 1991
1340 m2-exp.y Added range checking for numeric constants. Any numeric
1341 constant is assumed to be of builtin type INTEGER unless:
1342 (1) it is octal or hexadecimal, in which case it is a
1343 CARDINAL; (2) it is too big to fit into an INTEGER, in
1344 which case it is a CARDINAL.
1345 eval.c Added simple range checking for +, -, and * on integers.
1346 Doesn't work very well for *, since 6 * 1,000,000,000 =
1347 1,705,032,704, which fails the simple test of result >=
1348 first_operand, no matter in what order the operands are.
1350 Tue Jun 18 14:11:30 EDT 1991
1352 Broke the parser into parts, one containing the C grammar and the other
1353 containing code to be shared by all of the grammars.
1355 The following files no longer exist:
1360 The following files were added:
1362 c-exp.y (The C grammar)
1363 m2-exp.y (The Modula-2 grammar)
1364 parser-code.c (Code that is shared by the above grammar)
1368 Makefile.dist Changed to reflect the above dependencies. NOTE: It is
1369 now necessary to use the Bison compiler compiler, since it
1370 will generate function/variable prefixes other than yy.
1372 Tue Jun 18 16:47:49 EDT 1991
1374 symtab.[ch] Added the external variable working_lang, than holds the
1375 value of the current working language.
1376 Added the ennumerated type language_mode, with the values
1377 language_auto and language_manual, the former meaning that
1378 GDB sets working_lang as needed, and the latter meaning
1379 that the value of working_lang is totally under user
1381 symtab.[ch] Added the Modula-2 pervasive types INTEGER, CARDINAL,
1382 REAL, BOOLEAN and CHAR. Also added the type codes
1383 TYPE_CODE_BOOL and TYPE_CODE_CHAR.
1384 utils.c Added set_language_command and show_language_command to
1385 implement the GDB support commands "set language" and
1387 expression.h A number of identifiers were added to the type exp_opcode
1388 to facilitate Modula-2 builtin functions, integer
1389 division, and array indexing.
1391 Wed Jun 19 13:25:58 EDT 1991
1393 language.h Added the macro STRICT_TYPE, which evaluates to non-zero
1394 if the language specified by working_lang requires the use
1395 of strict typing of expressions. Eventually, even this
1396 will be able to be changed by the user.
1397 Added the macro RANGE_CHECK, which evaluates to non-zero
1398 if the language specified by working_lang requires the
1399 checking of a value against the domain of its type.
1400 Eventually, even this will be able to be changed by the
1402 language.[ch] Predicates involving types (simple_type, ordered_type,
1403 same_type, integral_type, numeric_type, character_type,
1404 boolean_type, float_type) are added. These predicates are
1405 based on the current value of working_lang, and are handy
1408 Wed Jun 19 15:39:34 EDT 1991
1410 eval.c Added the function type_array_rank which computes the rank
1412 valarith.c Added the funtion value_bool, which when given a integer
1413 value.h value (ie. struct value *) as an argument, it returns a
1414 boolean value (ie. struct value *) true if that integer
1415 is non-zero, and a boolean value false otherwise.
1416 valprint.c Added cases for TYPE_CODE_BOOL, so Modula-2 BOOLEAN values
1417 will print out properly.
1419 Wed Jun 19 16:36:34 EDT 1991
1421 valops.c Added the function value_capitalize, which returns it
1422 value.h argument capitalized if its argument is a lowercase
1423 letter, or the argument unchanged if its argument is not a
1425 valarith.c Added the function range_check_p, which returns non-zero
1426 value.h if its value argument is between the integral bounds upper
1428 Added the function range_check_enum_p, which makes sure
1429 that its value argument is a valid member of the domain of
1431 Added the function range_check_range_p, which makes sure
1432 its value argument lies between the upper and lower bounds
1433 of its type argument, which must be a ranged type.
1434 Added the function check_array_index, which range and type
1435 checks an index of an array.
1436 Added the function value_multi_subscript, which computes
1437 array[idx1,idx2...idxN], given a value array and an array
1438 of values representing indicies.
1439 values.c Changed value_from_long to work with TYPE_CODE_CHAR and
1440 unpack_long to work with TYPE_CODE_BOOL and
1443 Wed Jun 19 18:04:08 EDT 1991
1445 symtab.c Stored pervasive types in a structure and make
1446 lookup_pervasive_type() a lookup function that was based
1447 on working_lang. If lookup_pervasive_type() returned
1448 non-zero, then that value was returned (a fix, since
1449 before it simply wouldn't return the pervasive type.)
1450 language.h Added the macro CAST_IS_CONVERSION, which evaluates to
1451 non-zero if the language specified by working_lang means
1452 "conversion" when it says "cast".
1453 valops.c Added the function value_real_cast(), which performs a
1454 value.h *cast*, not a *conversion*, which is what value_cast()
1455 does when it can. In particular,
1456 value_cast(<float_type>,4) = 4.0, while
1457 value_real_cast(<float_type>,4) = some mess.
1458 eval.c Modula-2 builtin functions implemented: ABS, CAP, CHR,
1459 parser-code.c FLOAT, HIGH, MAX, MIN, ODD, ORD, TRUNC, and VAL.
1460 expression.h Added macros MAX_OF_TYPE and MIN_OF_TYPE to work with MAX
1461 and MIN on integral types. *NOTE*: These are currently
1462 hardcoded to work only if there are 8 bits per storage
1464 eval.c Made logical functions call value_bool to return a
1465 properly typed boolean value, based on working_lang.
1467 Thu Jun 20 11:55:27 EDT 1991
1469 valprint.c Types now print out in a Modula-2 fashion. This works for
1470 the cases when the type is printed out step-by-step, that
1471 is, it doesn't work when the name of a structured type
1472 (which includes the keyword "struct", etc.) is simply
1474 FIXME: Perhaps this is bad. Parts of it seem to kludgey,
1475 since type specifications in C and Modula-2 are very
1476 different. The C printing of a type is very recursive,
1477 whereas in Modula-2 it is generally very simple. C has
1478 type prefixes and suffixes, which have no real analogue in
1479 Modula-2. Maybe type_print() should call a language
1480 specific type printer. This is also advantageous if we
1481 compile GDB to exclude some of the languages. We'll just
1482 leave those functions out.
1484 Thu Jun 20 16:57:10 EDT 1991
1486 dbxread.c When reading the complete symbol table in (via
1487 psymtab_to_symtab()), the number and types of function
1488 arguments are added to a function type. define_symbol()
1489 calls add_param_to_type() to accomplish this.
1490 Assumption: when we come across a function definition
1491 (N_FUN symbol with an 'f' or 'F' in the name), its
1492 arguments will appear before another function definition.
1493 When a function is found, a pointer to its type is placed
1494 in the global in_function_type. Changes that
1495 add_param_to_type() makes are to this global.
1496 valprint.c The type of a function now includes (for Modula-2) the
1497 types of its parameters.
1498 eval.c Type checking and a check for the proper number of
1499 arguments is now done for function calls. Not sure of the
1500 impact this has on C++ member function yet.
1502 Thu Jun 20 19:58:48 EDT 1991
1504 valprint.c Rewrote the type printer. Broke it into two language
1505 specific parts, adding the functions type_print_m2() and
1507 An unfortunate consequence is this: if you debugging a C
1508 program in Modula-2 mode (why?), info types does not work
1509 well with regular expressions, since the types are printed
1510 out in Modula-2 terminology, but stored in C terminology.
1511 language.[ch] Added the functions new_type_last(), type_keyword(), and
1512 type_sep() to aid in the printing of typedefs.
1513 symtab.c Made the printing of typedefs as language independent as
1514 possible through calls to new_type_last(), type_keyword(),
1517 Fri Jun 21 11:50:26 EDT 1991
1519 dbxread.c Check all incoming ennumerated types. If it looks like
1520 Modula-2's BOOLEAN type, then change the type_code of the
1521 type to TYPE_CODE_BOOL so we can process it as a boolean
1523 valprint.c Replaced some of the 0x%x with calls to sprintf and
1524 hexformat() in val_print().
1525 language.[ch] Added the function hex_to_string(), which converts its
1526 integral argument to a hexadecimal number (format is
1527 language based) and returns the result as a string.
1529 Mon Jun 24 12:25:07 EDT 1991
1531 valprint.c Some functions call type_print_1() directly, instead of
1532 value.h using type_print(), so they can specify where (column) to
1533 print things. Since type_print() takes care of language
1534 dependence, that needs to be called first. Added a
1535 parameter depth to type_print() (so it is now like
1536 type_print_1). Changed type_print to type_print_at, and
1537 made type_print a macro that passes a depth argument of
1539 symmisc.c Changed all calls to type_print_1 to calls to
1541 Makefile.dist Made it possible to build GDB for a specific set of
1542 depend languages. Do this by passing a definition for the macro
1543 LANGS to make. LANGS should be a string containing a
1544 space-separated list of language names (ie. LANGS="c m2").
1545 The default is to build all languages. Note that grammar
1546 files must follow the naming convention of <lang>-exp.y.
1547 gdb.lang This holds the current value of the LANGS macro. It is
1548 examined every time make is called, and is updated if
1550 eval.c Added #ifdef _LANG_<lang> to these files.
1551 expread.c Still need to add them to dbxread.c and coffread.c.
1559 Mon Jun 24 16:33:11 EDT 1991
1561 language.[ch] Added the functions hexformat_pre() and
1562 hex_to_string_pre(), which take a prefix argument to
1563 include in the format string. Thus, hexformat_pre("08") will
1564 return "0x08x" (if the working language is language_c).
1565 Made hexformat() and hex_to_string() calls to the above
1566 with "" as the prefix argument.
1568 am29k-pinsn.c, arm-pinsn.c, breakpoint.c, convex-tdep.c, exec.c, core.c,
1569 dbxread.c, i386-pinsn.c, i386-stub.c, i386-xdep.c, i960-pinsn.c,
1570 infcmd.c, inflow.c, m68k-pinsn.c, m68k-stub.c, m88k-pinsn.c,
1571 mips-pinsn.c, mips-tdep.c, ns32k-pinsn.c, printcmd.c, pyr-pinsn.c,
1572 pyr-tdep.c, pyr-xdep.c, remote-vx.c, remote.c, solib.c, source.c,
1573 stack.c, sun386-xdep.c, symfile.c, symm-xdep.c, symmisc.c, tahoe-pinsn.c,
1574 valprint.c, vax-pinsn.c
1576 Changed all occurences of 0x%[0-9]*l*x in printf format strings to
1577 calls to hexformat() and hex_to_string(). Format strings without
1578 the leading "0x" were ignored.
1580 depend Updated to take the above into account.
1583 Tue Jun 25 15:27:18 EDT 1991
1585 symtab.h Added the types range_mode_t, range_check_t, type_mode_t,
1586 and type_check_t to keep track of the current state of
1587 range and type checking.
1588 main.c Added the variables range_mode, range_check, type_mode,
1589 and type_check to record the current state of range and
1590 type checking. Added initialization code to main().
1591 language.h Changed the macros STRICT_TYPE and RANGE_CHECK to examine
1592 the above variables.
1595 Tue Jun 25 17:57:08 EDT 1991
1597 dbxread.c process_one_symbol() updates the variable (enum language)
1598 source_lang based on the extension of the filename
1599 contained in the N_SO sybmol that started this symtab.
1600 When end_symtab() is called, the value of source_lang is
1601 put into the language field.
1602 stack.c select_frame() sets working_lang (and possibly type_check
1603 and range_check) to the language field of the symtab
1604 associated with the frame that is selected if working_mode
1605 is language_auto. If working_mode is language_manual, a
1606 warning is printed and working_lang is not set.
1607 language.c Added the function set_type_range(), which sets the value of
1608 type_check and range_check (if their modes call for
1609 automatic setting) based on the current value of
1610 working_lang. A non-zero argument will cause the current
1611 settings to be output.
1614 Wed Jun 26 14:51:40 EDT 1991
1616 eval.c Added range checks on assignment.
1617 m2-exp.y Added the grammar for sets to the language. Currently,
1618 these do not do anything except print an error message.
1620 Wed Jun 26 17:01:04 EDT 1991
1622 m2-exp.y Added the ability for parse_number() to parse negative
1623 numbers. A global flag is set upon encountering a unary
1624 minus. This was done to make, for example, 1 parse as a
1625 CARDINAL, and not as an integer, per Wirth's examples in
1626 Programming in Modula-2 ed.4.
1627 valprint.c Added support for "set radix 2" by then setting
1628 output_format to 't'.
1629 eval.c Implemented range checking on subrange types. Added calls
1630 to range_check_range_p for BINOP_ASSIGN and BINOP_VAL.
1631 Implemented MIN and MAX for ennumerated types. The
1632 minimum value of an ennumerated type is defined by Wirth
1633 as the first identifier, and the maximum as the last.
1634 m2-exp.y Made octal numbers ending with "B" be characters and those
1635 ending with "C" be numbers, per Wirth's book. (p. 34)
1637 Thu Jun 27 14:11:52 EDT 1991
1639 stack.c select_frame() now only sets working_lang, it does not
1640 notify the user. If working_mode is language_manual, then
1641 a warning is issued once.
1642 main.c At the end of each call to execute_command(), working_lang
1643 is checked against the local static (enum language)
1644 current. If they differ and working_mode is
1645 language_auto, the new settings of language, type and
1646 range checking are printed out.
1647 stack.c Modified frame_info() to include the language of the
1648 current frame in the output of "info frame".
1649 language.[ch] Added the function language_str() which returns the name
1650 of the current language.
1652 Fri Jun 28 15:33:14 EDT 1991
1654 m2-exp.y Added the built-in procedures INC, INCL, DEC, and DECL to
1655 the language. INCL and DECL currently cause an error,
1656 since sets are not implemented yet. INC and DEC are
1657 implemented as PREINCREMENT/PREDECREMENT with one
1658 argument, and as ASSIGN_MODIFY with two arguments.
1659 eval.c Added type checking to the above cases.
1660 value.h Added not_lval_constant to the lval_type ennumerated type.
1661 not_lval_constant means that the value is a constant
1662 value; that is 3 or 'a' or TRUE, not as in a constant
1663 identifier. This is used to help coerce numbers such as 3
1664 to either signed or unsigned numbers.
1665 valops.c Added the function value_coerce_constants() which coerces
1666 constant integers as following: if one is a constant and
1667 the other is not, the constant's type is set to the type
1668 of the other argument. If both are constants and one is
1669 signed, the other is converted to a signed constant.
1671 Sat Jun 29 17:26:29 EDT 1991
1673 valarith.c Added a better range checker. It now checks range
1674 (successfully) on integral operations [+-] (signed and
1675 unsigned) for any C sized type. Still does not work well
1676 for multiplication.)
1677 int_in_size() returns an integer that is coerced to fit into
1678 specified number of bytes.
1680 Mon Jul 1 13:04:14 EDT 1991
1682 language.[ch] Added the function binop_result_type(), which returns the
1683 builtin (struct type *) type that would be the result of a
1684 binop on the two values V1 and V2.
1686 Wed Jul 3 19:22:53 EDT 1991
1688 source.c Extended source_info() to include the source language in
1689 the output from "info source".
1691 Fri Jul 5 13:48:52 EDT 1991
1693 utils.c Moved the support functions for the GDB set/show commands
1694 dealing with language into language.c.
1695 language.c Added the function language_info(), which displays info
1696 about the current working language, type and range check
1697 settings. Called via the GDB command "info language".
1698 Added an initialization routine _initialize_language(),
1699 that sets defaults for the language, type and range
1700 variables and sets up the new GDB commands.
1701 main.c Language setup moved to language.c.
1704 Mon Jul 8 10:10:22 EDT 1991
1706 valarith.c Debugged the range checker for arithmetic. Still does not
1707 work for multiplication very well.
1709 Mon Jul 8 12:40:37 EDT 1991
1711 language.[ch] Added the function value_true() which returns non-zero if
1712 its argument represents a boolean true value.
1713 breakpoint.c Changed breakpoint_cond_eval() to call value_true() to
1714 check the truth of an expression.
1716 Thu Jul 11 12:51:34 EDT 1991
1718 language.[ch] Added the predicate structured_type(), which returns
1719 non-zero if the argument is a structured type.
1720 Added the predicate pointer_type(), which returns non-zero
1721 if the argument is a pointer type.
1722 eval.c Added the ability to do addition and substraction on
1723 pointers and integers. This case simply bypasses the
1726 Thu Jul 11 14:41:42 EDT 1991
1729 Added the symbol N_DEFD (0x4a) which is a definition
1730 module dependency that is used by the GNU Modula-2
1731 compiler and the linker. It is not important to GDB,
1732 except that [dbx|coff|mips]read.c should ignore these
1735 Fri Jul 12 16:07:00 EDT 1991
1737 valprint.c Changed the TYPE_LENGTH(type) >= 0 to TYPE_LENGTH(type) >
1738 0 in val_print(). Also added statements to the else part
1739 to coerce type (argument to val_print) to a pointer type
1740 if it is an "array of unspecified length".
1741 valops.c Added the function value_m2_string(), which returns a
1742 (value) value which is a constant string, whose type is
1743 (ARRAY [0..n] OF CHAR). The length field of the type
1744 structure is set to zero, so it will be interpreted as an
1745 "array of unspecified length".
1746 stack.c Moved the language/frame mismatch check to
1747 main.c:execute_command().
1748 main.c The working language is recorded each time
1749 execute_command() is executed. If working lang has
1750 changed during its execution, then the new
1751 language/type/range info is printed out for the user. If
1752 the working language does not match the language of the
1753 frame, a warning is issued.
1755 Sat Jul 13 16:16:39 EDT 1991
1757 eval.c Moved all the type-checking stuff for operators to
1758 language.[ch] language.c. This is so we can keep language-specific
1759 stuff (like for what type operators are defined) in
1761 language.[ch] Added the function binop_type_check(), which checks to see
1762 if its two (value) arguments are type-compatible with its
1763 opcode argument. The opcode should represent an operation
1764 involving an operator. Also added the macro function
1765 unop_type_check, which calls binop_type_check with a
1766 NULL second argument.
1767 expprint.c Added Modula-2 operators to the op_print_tab, so info
1768 expression.h break works correctly. Also added "op_string", which
1769 returns the string corresponding to the (enum exp_opcode)
1770 opcode that is its argument.
1773 Sat Jul 13 18:26:18 EDT 1991
1775 coffread.c Added code to record the type of function arguments with
1776 each paricular function. Code is very similar to that
1778 dbxread.c Moved add_param_to_type() to symtab.c
1779 symtab.[ch] Added function add_param_to_type() from dbxread.c
1781 *** NOTE: The above additions have not been tested.
1783 Mon Jul 15 12:50:47 EDT 1991
1785 langauge.[ch] Added the functions type_error and range_error, which work
1786 like error() except if the type/range mode is set to
1787 *_mode_warn, then they do not do a return_to_top_level(),
1788 but merely print a warning.
1789 Also changed [set|show]_[type|range]_command() to support
1790 the new "warn" feature.
1792 Thu Jul 18 17:50:54 EDT 1991
1794 mipsread.c Added code to record the type of function arguments with
1795 each particular function. Code is very similar to that
1798 *** NOTE: The above additions have not been tested.
1800 Fri Jul 19 11:19:10 EDT 1991
1802 defs.h Added macros MAX_OF_SIZE, MIN_OF_SIZE, UMAX_OF_SIZE, and
1803 UMIN_OF_SIZE, which when given a size of a numeric type,
1804 return the maximum and minimum value it can hold. UMAX...
1805 and UMIN... return the result for unsigned types.
1806 symtab.h Added the macros MAX_OF_TYPE and MIN_OF_TYPE to operate on
1807 struct types. They call above macros.
1808 dbxread.c Renamed the MAX and MIN_OF_TYPE macros to ..._OF_CTYPE to
1809 avoid a name conlict with the above.
1810 c-exp.y Added range checking on numeric constants in
1811 parse_number() for completeness.
1812 valarith.c Made binop_user_defined_p() and unop_user_defined_p()
1813 return 0 if working_lang is not language_c.
1815 Thu Aug 8 14:17:22 EDT 1991
1819 breakpoint.c Documentation strings of some commands changed to
1820 eliminate the references to the C language where
1823 Tue Aug 13 15:48:03 EDT 1991
1825 m2-exp.y Added qualified identifiers to the grammar. The semantics
1826 are slightly different from those of the GDB operator ::
1828 m2-exp.y Added a rule to each grammar of the form: start ::= exp |
1829 type_exp, where type_exp is any valid type expression.
1831 eval.c Added the opcode OP_TYPE, and an error case in eval.c.
1832 printcmd.c Modified ptype_command() so it actually parses the input
1833 (necessary for type expressions with scope qualifiers).
1834 Added the function ptype_eval() which expects an
1835 expression composed of one OP_TYPE element.
1836 *.[ch] Replaced all occurences of parse_c_expression with
1838 *.[ch] Replaced all occurences of parse_c_1 with parse_exp_1
1840 [End of ChangeLog entries from Andrew Beers for Modula-2 support.]
1842 Mon Sep 16 17:19:46 1991 John Gilmore (gnu at cygnus.com)
1844 Small fixes from Peter Schauer:
1846 * infrun.c (child_attach): Lint.
1847 * solib.c (find_solib): Handle shared libs version 2.
1849 Small fixes from David Wood:
1851 * xm-ultra3.h (SYS_SIGLIST_MISSING): Typo.
1855 * remote-vx.c: Move <stdio.h> to top, for FILE. Fix from
1856 John S <basrai%kanga.dnet@c3po.sm-alc.af.mil>.
1858 * utils.c (wrap_here): Avoid wrap action of fputs_filtered if
1859 chars_per_line is at maximum (user typed `set width 0'). Fix
1860 from Andreas Schwab <schwab@ls5.informatik.uni-dortmund.de>.
1862 Tue Sep 17 17:31:04 1991 Stu Grossman (grossman at cygnus.com)
1864 * coredep.c: include ptrace.h where necessary.
1865 * mipsread.c(parse_lines): fix unsigned char problem that was
1866 messing up line numbers on SGI's and possibly other MIPS based
1868 * infrun.c (child_create_inferior): use better test to check
1869 return val from setpgrp().
1870 * tm-irix3.h, xm-irix3.h, tconfig/irix3, xconfig/irix3: add these
1871 for sgi/irix support.
1873 Wed Sep 18 04:33:31 1991 Per Bothner (bothner at cygnus.com)
1875 * mipsread.c (parse_symbol): Put non-static procedures
1876 in the global block.
1878 Fri Sep 13 00:14:52 1991 John Gilmore (gnu at cygnus.com)
1880 Patch together `text_start' and `text_end' for 29K port.
1882 * exec.c (exec_command): If NEED_TEXT_START_END, define the
1883 variables and set them based on the exec file.
1884 * am29k-tdep.c: declare text_start.
1885 * valops.c (call_function_by_hand): declare text_end.
1887 * inferior.h: Eliminate CANNOT_EXECUTE_STACK in favor of
1888 defining CALL_DUMMY_LOCATION as BEFORE_TEXT_END. This is
1889 because machines that do this will also have to know to
1890 set NEED_TEXT_START_END. Besides, it was a redundant way to
1892 * tm-29k.h, tm-convex.h, tm-np1.h: Eliminate
1893 CANNOT_EXECUTE_STACK, define CALL_DUMMY_LOCATION and
1894 NEED_TEXT_START_END.
1896 Thu Sep 12 00:22:24 1991 John Gilmore (gnu at cygint.cygnus.com)
1898 AMD 29000 changes from David Wood <wood@david.ultra.nyu.edu>:
1900 * Makefile.in (CLIBS): Put XM_CLIBS and TM_CLIBS at end.
1901 Pass MUNCH_DEFINE to munch whenever we run it.
1902 * am29k-pinsn.c (print_insn): Handle NOP specially. Avoid %#x
1903 format string; use 0x%x instead.
1904 * am29k-tdep.c: Use DUMMY_SAVE_GREGS and RETURN_REGNUM.
1905 * ultra-xdep.c, xm-ultra.h: New files for Ultracomputer host system.
1906 * xm-rtbsd.h: New host support for RT/PC running BSD Unix.
1907 * inflow.c: Handle `short' process group IDs.
1908 * infptrace.c (fetch_register): Support CANNOT_FETCH_REGISTER,
1909 and check for ptrace errors.
1910 * coffread.c (SDB_REG_TO_REGNUM): Define if not already.
1911 (coff_symfile_init): Initialize text_bfd_scnum.
1912 (read_coff_symtab): Use it to find the text [and absolute?] sections.
1913 * ../config.sub: Add vendor nyu and os "sym[1-9]*".
1914 * configure.in: Add hosts rtpc-*-* and a29k-*-*.
1915 Merge target arm case with other "easy" cases. Add target
1916 cases a29k-*-none (rehack of am29k), a29k-*-kern (remote to
1917 Ultracomputer kernel), and a29k-*-sym1 (ultracomputer OS's user
1919 * minimon.h, remote-adapt.c, remote-mm.c: Add.
1920 * munch: Cope with RT/PC putting fns in data segment.
1921 Restore ability to override `nm' by specifying MUNCH_NM.
1922 * xconfig/rtbsd, xconfig/ultra3: New host systems.
1923 * tconfig/a29k: Rename from tconfig/am29k. Add remote-mm
1924 and remote-adapt. Remove encapsulated coff #define's (the
1925 support should go in BFD, and gdb shouldn't know or care).
1926 * tconfig/a29k-kern: Same, but for remote kernel debugging.
1927 * tconfig/ultra3: For debugging user processes on Ultra3/Sym1.
1928 * tm-29k.h: Update BADMAG (though it should go away).
1929 Allow the register definitions to be overridden in another
1930 tm-file. Fix SR_REGNUM. Add a mess of _REGNUM's. Separate
1931 RETURN_REGNUM from GR96_REGNUM and DUMMY_SAVE_GREGS from
1932 DUMMY_SAVE_GR96, for handling kernel calling conventions
1933 that use GR64+ rather than GR96+.
1934 * tm-ultra3.h: New file, for use on Ultra3 Unix as well as for
1935 remote debugging of Ultra3 kernel. Includes tm-29k.h and
1936 overrides various things.
1938 * remote-mm.c (mm_attach, mm_wait): Handle attach like
1939 child_attach does, making a clean stop in the newly attached
1941 * remote-eb.c: Lint.
1943 * coffread.c: Make coffread independent of any particular
1944 variant of COFF. Avoid #include-ing any particular one except
1945 internalcoff.h. BFD now passes key values for symbol reading
1946 as part of its coff_data structure (LINESZ, SYMESZ, AUXESZ,
1947 and the symbol masks and shifts); use them.
1948 Remove obsolete end_of_text_addr.
1950 * exec.c: Remove unused include files.
1952 Wed Sep 11 19:38:44 1991 John Gilmore (gnu at cygint.cygnus.com)
1954 * Makefile.in (documentation targets): Pass $(M4).
1955 Bugfix from eggert@twinsun.com (Paul Eggert).
1957 * stack.c (down_silently_command): Check for stack existence.
1959 Tue Sep 10 23:08:29 1991 John Gilmore (gnu at cygint.cygnus.com)
1961 * Makefile.in (VERSION): Update to 4.0.3.
1963 Tue Sep 10 09:19:29 1991 John Gilmore (gnu at cygint.cygnus.com)
1965 * core.c (core_file_command): Print frame at coredump with
1966 its level number, by calling print_stack_frame.
1967 * frame.h: Add selected_frame_level, print_stack_frame.
1968 * frame.h, stack.c: Remove print_sel_frame, print_selected_frame.
1969 * convex-tdep.c, convex-xdep.c, infcmd.c, inflow.c, infrun.c:
1970 Change print_sel_frame and print_selected_frame callers to
1973 * dbxread.c (read_ofile_symtab): Avoid empty else clause.
1974 * symfile.c (free_named_symtabs): Ditto.
1975 * main.c (main): wrap_here needs an arg.
1976 * solib.c (find_solib): Avoid memory access if _DYNAMIC is zero.
1977 (solib_add): Avoid noise.
1978 (solib_create_inferior_hook): Lint.
1979 (sharedlibrary_command): Move dont_repeat to here.
1980 * utils.c (error): Call wrap_here to force buffered output.
1982 Small patches from Peter Schauer:
1984 * coffread.c (start_symtab): Free any existing line_vector before
1986 (read_coff_symtab): Ditto for type_vector.
1988 * source.c (lines_to_list): New variable, replacing function.
1989 (all uses): Use as variable.
1990 (_initialize_source): Add 'set listsize' and 'show listsize'.
1991 * utils.c (lines_to_list): Remove function.
1992 * stack.c (print_frame_info): Use as variable.
1993 * defs.h (lines_to_list): Remove declaration.
1995 Mon Sep 9 13:45:57 1991 John Gilmore (gnu at cygint.cygnus.com)
1997 * breakpoint.c (insert_breakpoints): Restore warning about
1998 the program might be running in another process, but only for
1999 systems with this brain death (#ifdef ONE_PROCESS_WRITETEXT).
2000 * xm-hp300bsd.h, xm-mips.h, xm-vax.h: Define it.
2002 * utils.c (error): if error_pre_print is set, print the string
2004 * main.c (main, print_gnu_advertisement, print_gdb_version):
2005 Reformat legalese so it always prints, but acts as an "I'm here"
2006 message while symbols are being read. If any errors occur,
2007 print a few newlines to set off the message and start it at the
2008 left margin. Remove mention of "help" command, and don't yak
2009 about symbol reading.
2010 (catch_errors): Error string is now printed first in case of
2012 * command.c (undef_cmd_error, lookup_cmd): On undefined command,
2013 suggest the "help" command.
2015 * Makefile.in (VERSION): Set to 4.0.2.
2017 Thu Sep 5 23:49:48 1991 John Gilmore (gnu at cygint.cygnus.com)
2019 * .gdbinit: Remove useless "rr" command. Set complaints
2020 to 1 for people debugging gdb.
2022 * breakpoint.c, remote-vx.c: Reword strings printed by
2023 catch_errors callers.
2025 Wed Sep 4 11:07:50 1991 John Gilmore (gnu at cygint.cygnus.com)
2027 * WHATS.NEW: "history write -> history save". Doc "write on/off".
2028 (Fix from kenc@viewlogic.com.)
2030 Fix some infrastructure to be able to cope with host and target
2031 machines with different sized basic types (ints, ptrs, etc).
2032 (Idea from pierre@la.tce.com (Pierre Willard).)
2034 * values.c (value_from_longest): Rename from value_from_long.
2035 Handle pointer types as well as integers, so that targets with
2036 different pointer sizes from the host can be accomodated.
2037 * breakpoint.c, convex-tdep.c, eval.c, expprint.c, printcmd.c,
2038 valarith.c, valops.c, valprint.c, value.h, values.c: Rename
2039 uses of value_from_long to value_from_longest.
2040 * eval.c, findvar.c, printcmd.c, valarith.c, valops.c: Pass
2041 the correct pointer type to value_from_long{est}.
2043 * doc/gdb.texinfo ($_, $__): Describe types of these variables.
2045 * remote-vx.c: Remove obsolete code for calling functions via
2046 vxworks kludge interface (it referenced value_from_long).
2048 * valops.c (value_string): Find malloc with lookup_misc_func, not
2051 Tue Sep 3 18:37:46 1991 John Gilmore (gnu at cygint.cygnus.com)
2053 Make writing to files work properly. (Fixes to BFD are also needed.)
2055 * core.c (core_open): Open file ourselves, read or r/w, depending on
2056 write_files. Use bfd_fdopenr.
2057 * gdbcore.h (write_files): New variable.
2058 * exec.c (write_files): Define variable, add set&show for it.
2059 (exec_file_command): Use write_files to open for read or r/write.
2061 Make shared library reading happen automatically. These changes
2062 are mostly from Peter Schauer <pes@regent.e-technik.tu-muenchen.de>.
2064 * inferior.h (stop_soon_quietly): Add to exported variables.
2065 * infrun.c (child_create_inferior): call solib hook, if defined.
2066 (child_attach): call solib hook, if defined.
2067 * solib.c: Include inferior.h. Add from_tty to so_list as kludge.
2068 (find_solib): Use lookup_misc_func rather than hand-rolled.
2069 (symbol_add_stub): New stub for catch_errors.
2070 (solib_add): Avoid output if !from_tty. Catch errors rather
2071 than just calling symbol_file_add and bombing.
2072 (solib_create_inferior_hook): Interface with the target process
2073 to let it read and alloc shared libs, then figure out what it did.
2075 * core.c (validate_files): Fix typo, soften warning.
2076 (Fix from Hiroto Kagotani <kagotani@cs.titech.ac.jp>.)
2078 * utils.c (fputs_demangled): Avoid duplicate printing if
2079 demangling is off. (Fix from J.T. Conklin <jtc@cayenne.com>.)
2081 * infrun.c (proceed): Cast -1 to (CORE_ADDR) before comparing.
2082 (Fix from pierre@la.tce.com (Pierre Willard).)
2084 * main.c (catch_errors): Change argument to a char * from an int,
2085 since a char * can point to a struct full of glop, but an int
2086 is not guaranteed to be able to hold a pointer.
2087 * breakpoint.c (breakpoint_cond_eval, bpstat_stop_status,
2088 breakpoint_re_set_one, breakpoint_re_set): Adapt.
2089 * core.c (core_open, solib_add_stub): Adapt.
2090 * remote-vx.c (symbol_stub, add_symbol_stub, callers): Adapt.
2092 Wed Aug 28 18:18:05 1991 John Gilmore (gnu at cygint.cygnus.com)
2094 * Makefile.in: Update VERSION to 4.0.1. Evade GNU Make bug
2095 by adding .NOEXPORT target.
2097 Fri Aug 23 17:14:25 1991 John Gilmore (gnu at cygint.cygnus.com)
2101 * Makefile.in (VERSION): Roll to 4.0.
2102 (gdb.tar.Z): Make refcard.ps as well, for shipment.
2104 Fri Aug 23 14:07:09 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
2106 * doc/gdb.texinfo: minor rewordings, crossref to ptype from print,
2109 * doc/Makefile, Makefile.in: generate "gdb-all.texi" rather than
2112 * doc/rdl-apps.texi: renamed from rdl-apps.texinfo
2114 * Makefile.in, doc/Makefile, doc/.Sanitize, doc/gdb.texinfo:
2115 reflect above name change
2117 * WHATS.NEW: correct pointer to refcard.
2119 * doc/gdb.texinfo: update New Features, Installing
2121 * doc/gdbint.texinfo: add short description of configure +template
2123 Fri Aug 23 11:46:08 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
2125 * doc/gdb.texinfo: update, fix bugs in "Installing" appendix
2127 Fri Aug 23 01:02:00 1991 John Gilmore (gnu at cygint.cygnus.com)
2129 * Makefile.in: Add config.sub, make doc/rdl-apps.texinfo for
2130 tar file, add dependencies for referenced doc files.
2132 Thu Aug 22 22:17:06 1991 Stu Grossman (grossman at cygint.cygnus.com)
2134 * coffread.c, symfile.c, stack.c: saberized.
2136 Thu Aug 22 16:20:27 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
2138 * doc/refcard.tex: permuted Essential Commands sec
2140 * doc/gdb.texinfo: new C++ chapter; revised installation appendix;
2142 set/show symbol-reloading
2143 default set complaints 0
2145 RET-repeat disabled after prompted long displays
2146 processID (attach) interpretation of 2nd GDB cmdline arg
2148 Thu Aug 22 14:05:47 1991 Stu Grossman (grossman at cygint.cygnus.com)
2150 * expread.y, coffread.c, dbxread.c, target.c, mem-break.c,
2151 cplus-dem.c, values.c, valprint.c, symfile.c, remote.c,
2152 breakpoint.c, main.c: lint.
2154 Thu Aug 22 02:02:26 1991 John Gilmore (gnu at cygint.cygnus.com)
2156 Install new configuration scheme for GDB and friends.
2158 * config.sub: Translate ordinary names to three-part names.
2159 * configure: Use three-part names internally.
2160 * configure.in: Translate three-part names to filenames.
2162 * README, WHATS.NEW: Update for gdb-4.0.
2163 * Makefile.in: Roll VERSION to 3.99.
2165 Wed Aug 21 18:21:09 1991 John Gilmore (gnu at cygint.cygnus.com)
2167 * infptrace.c (KERNEL_U_ADDR_BSD): Include a.out.gnu.h.
2168 * i960-tdep.c, m68k-tdep.c, sparc-tdep.c, tm-i960.h,
2169 tm-m68k.h, remote-nindy.c: Change ext_format_XXX structs
2170 to single structures rather than arrays; when passing
2171 their address, use &. This avoids trouble with bdead compilers.
2172 * mcheck.c: Don't include <stdlib.h>; just declare "void abort();"
2173 instead. This avoids portability headaches.
2174 * mips-tdep.c (mips_do_registers_info): Only print FP regs if
2176 * source.c (open_source_file): Avoid ANSI const bdeath by
2177 skipping declaration and then casting result value.
2178 * tm-hp300bsd.h: Clarify comment.
2179 * utils.c (strstr): Result is const char *; ANSI bdeath.
2180 * xm-hp300bsd.h: Define HOST_BYTE_ORDER. Redefine INT_MIN,
2181 since system include file defines it differently from "defs.h",
2182 though the two are equivalent for our purposes.
2183 * tconfig/hp300bsd: Add m68k-tdep.o.
2185 Tue Aug 20 16:01:11 1991 John Gilmore (gnu at cygint.cygnus.com)
2187 * tconfig/sun*4: Remove warnings about system assembler.
2189 Mon Aug 19 13:44:46 1991 John Gilmore (gnu at cygint.cygnus.com)
2191 * mcheck.c: Avoid warning about undeclared abort fn.
2192 * tm-sparc.h (PC_ADJUST): Avoid calling error() from this;
2193 it causes recursive calls to error() when used in cleanups.
2194 To do so requires that we make it a function, so we do.
2195 * sparc-tdep.c (sparc_pc_adjust): New implem of PC_ADJUST.
2196 * utils.c (do_cleanups): Remove the current cleanup from the
2197 chain *before* calling it, in case error() is called from it.
2198 The result won't be pretty, but won't be an infinite loop either.
2200 Mon Aug 19 00:41:04 1991 Michael Tiemann (tiemann at cygint.cygnus.com)
2202 * dbxread.c (read_struct_type): Grok anon structs for C++.
2203 (vb_name, vptr_name): Null terminate these strings.
2205 Fri Aug 16 08:31:03 1991 John Gilmore (gnu at cygint.cygnus.com)
2207 Minor bug fixes from BSD Net2 gdb:
2209 * blockframe.c (get_prev_frame_info): If FRAME_CHAIN_COMBINE
2210 returns 0, there is no previous frame.
2211 * breakpoint.c (commands_command): If !from_tty, don't call
2212 input_from_terminal_p().
2213 * dbxread.c (record_misc_function): Speed up slightly.
2214 (compare_psymbols): Ditto.
2215 * infcmd.c (do_registers_info): Take a second argument to
2216 determine whether to print float registers. "info registers"
2217 does not do so anymore. "info all-registers" does, now.
2218 * mips-tdep.c, pyr-tdep.c (xxx_do_registers_info): Take second
2220 * tm-mips.h, tm-pyr.h (DO_REGISTERS_INFO): Pass second arg.
2221 * inflow.c (initialize_inflow): Set tflags_ours correctly.
2225 * breakpoint.c (bpstat_do_actions): Use a cleanup to restore
2226 executing_breakpoint_commands if we are interrupted by error.
2227 * coffread.c (init_lineno): Avoid problem with zero-sized linetab
2228 versus malloc/free. From: john@labtam.labtam.oz.au (John Carey).
2229 * core.c (solib_add_stub, core_open): Call SOLIB_ADD inside a
2230 catch_errors() so we can setup the frame regardless of whether
2231 the shared libs work.
2232 * ieee-float.c (double_to_ieee_extended): Get exponent from
2233 right place in little-endian systems. From John Carey.
2235 Thu Aug 15 18:43:57 1991 John Gilmore (gnu at cygint.cygnus.com)
2237 * main.c: Remove unused terminating_signals and catch_termination().
2238 (long_options): Terminate with a zero element.
2239 [Bugfix from Atsuo Kawaguchi <atsuo@hark86.harl.hitachi.co.jp>.]
2240 (gdb_readline): Make call-compatible with readline.
2241 (init_signals): Improve comments re vfork vs. signal.
2243 * utils.c (prompt_for_continue): Use new gdb_readline().
2244 If we prompt for continuation, we don't let CR repeat the previous
2245 command, once we get back to a prompt. It's too easy to keep
2246 hitting CR, expecting "--more--" prompts, and have some long
2247 command start repeating on you.
2249 Tue Aug 13 16:17:56 1991 John Gilmore (gnu at cygint.cygnus.com)
2251 * blockframe.c (frameless_look_for_prologue): Speed up by
2252 calling SKIP_PROLOGUE_FRAMELESS_P if it's defined.
2253 * tm-sparc.h (SKIP_PROLOGUE, SKIP_PROLOGUE_FRAMELESS_P):
2254 Define two variants, one faster.
2255 * sparc-tdep.c (sparc_frame_chain): Use target_read_memory
2256 and return zero, rather than giving an error.
2257 (setup_arbitrary_frame): Initialize the PC in the new frame.
2258 (skip_prologue): Add a second arg saying whether we're just
2259 checking for a frameless function or not.
2261 * core.c (core_open, core_close, core_xfer_memory): Move
2262 section table pointers and bfd* into the target_ops.
2263 (core_open): Allow errors in shared lib reading, etc.
2264 (core_files_info): Describe shared library sections.
2266 * exec.c (exec_open, exec_close, exec_xfer_memory, xfer_memory,
2267 exec_files_info, set_section_command): Move section table
2268 pointers and bfd* into the target_ops.
2269 (add_to_section_table): Add BFD to section table.
2271 * target.c (target_xfer_memory, target_info): Pass target to
2272 xfer_memory and target_info functions.
2275 * gdbcore.h: Move struct section_table.
2276 * target.h: New home of struct section_table.
2278 * solib.c (solib_add): New argument is the target_ops whose
2279 section list is to be added to, if any. Reallocate the
2280 sections in that target to add any that come from shared libs.
2281 (throughout) so_sections renamed to sections.
2282 (solib_xfer_memory): Deleted.
2283 * tm-sunos.h (SOLIB_ADD): Add target argument.
2284 (SOLIB_XFER_MEMORY): Delete.
2286 * core.c, exec.c, inftarg.c, remote-eb.c, remote-nindy.c,
2287 remote-vx.c, remote.c, target.c, target.h: Remove add_syms vector
2288 from target_ops. It's the same on all targets. Add two section
2289 pointers to target_ops.
2291 * stack.c (find_relative_frame): Dump ancient algorithm for
2292 "down", just use handy "next" pointers.
2293 (frame_command): Don't error if there is no stack; let user
2296 * inflow.c (new_tty_prefork, new_tty): New prefork routine
2297 modifies static state in the parent process; new_tty itself
2298 runs in the child and modifies the child's file descriptors
2299 to match the saved static state.
2300 * infrun.c (child_create_inferior): Call new_tty_prefork,
2303 * infptrace.c (child_xfer_memory): Add ignored target arg.
2304 * remote-eb.c (eb_xfer_inferior_memory): ''
2305 * remote-nindy.c (nindy_xfer_inferior_memory): ''
2306 * remote-vx.c (vx_xfer_memory): ''
2307 * remote.c (remote_xfer_memory): ''. Rename from
2308 remote_xfer_inferior_memory.
2310 * main.c (main): Only try to attach "corefile" argument if
2311 it starts with a digit.
2313 * symfile.c (symbol_reloading): New "set/show" variable.
2314 (symbol_file_add): Shorten message about symbol reading.
2315 (add_symbol_file_command): Merge with add_syms_addr_command,
2316 since this should work on all targets now.
2317 (stop_whining): Default to zero, to shut up complaints
2318 about bad symbol tables on many systems.
2319 (free_named_symtabs): Just exit unless symbol_reloading.
2321 * xm-sun3os4.h, xm-sun4os4.h: Define BROKEN_LARGE_ALLOCA,
2322 and add comment explaining shared library screw.
2324 * source.c: #if defined => #ifdef.
2326 Thu Aug 8 12:23:19 1991 John Gilmore (gnu at cygint.cygnus.com)
2328 * doc/gdbint.texinfo: Improve doc on porting to new OS's.
2330 Tue Aug 6 17:16:15 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
2332 * doc/rdl-apps.texinfo: provide default readline-appendix finder
2333 (doc/Makefile knows how to make one for local config)
2335 * Makefile.in: use doc/Makefile for doc targets
2337 * doc/Makefile: GDB documentation now has its own Makefile
2338 doc/refcard.tex: renamed from "gdbrc.tex"
2339 doc/.Sanitize: add Makefile; recognize renamed refcard.tex
2340 doc/gdbint.texinfo: add markup in "Cleanups" chapter
2343 Fri Aug 2 00:13:06 1991 John Gilmore (gnu at cygint.cygnus.com)
2345 * values.c (baseclass_addr): When reading target memory, use the
2346 length of the basetype, not the upper type. We've only malloc'd
2347 enough space for the basetype, leading to errors in free().
2349 * expprint.c (print_subexp): Print UNOP_MEMVAL of an OP_LONG that
2350 ends up as a function specially, since we know the actual type of
2351 the pointed-to address. This (somewhat) fixes display of
2352 expressions that include misc_function_vector names. Try `cond 1
2353 !strcmp("a","b")' then `i b'.
2355 * infrun.c: Move DO_DEFERRED_STORES from proceed() to resume().
2356 The child can be proceeded from inside wait_for_inferior in
2357 evaluating breakpoint conditions, and DO_DEFERRED_STORES was
2358 getting skipped in that case.
2360 * expprint.c (print_subexp): Use filtered output, since the
2361 subroutines we call use it, otherwise the output is horribly
2362 mangled, since output of wrappable stuff comes out late.
2364 * Makefile.in: Bump VERSION to 3.98.1
2366 * infrun.c (child_create_process): Use execlp to find the
2367 shell to exec our target program. This requires some fiddling
2368 with `environ' since there is no execlpe().
2370 Thu Aug 1 15:35:17 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
2372 * Makefile.in, doc/gdbrc.tex, doc/rc-* (new files):
2373 Minor rearrangement of refcard permits two new make targets--
2374 gdbrc.dvi DVI output for refcard, using CM fonts
2375 gdbrc.ps PostScript refcard, using PS fonts
2377 Wed Jul 31 16:46:21 1991 John Gilmore (gnu at cygint.cygnus.com)
2381 * TODO, Projects, WHATS.NEW, README: Update for gdb-3.98.
2382 * Makefile.in (gdb-all.texinfo): Avoid touching file if M4 dies.
2384 Wed Jul 31 16:35:58 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
2386 * doc/gdb.texinfo: last changes for release.
2387 Minor typo and formatting fixes; incorporated most fixes remaining from
2388 filed mail commenting on earlier drafts.
2390 Added warnings: pipes don't work in run command;
2391 conditions are converse of assertions;
2392 step over fn without debug info goes to next fn;
2393 vars may have "wrong" values near fn entrance, exit
2395 Added example from Kingston on printing repeated nonadjacent values
2397 Added explicit mention that in Emacs gdb mode C-c and C-z are like
2398 shell mode for signals
2400 Renamed "Stepping and Continuing" to "Continuing and Stepping" so it
2401 doesn't sound so much like its parent "Stopping and Continuing"; also
2402 moved entries on continue to top of section, so they don't get lost.
2404 Improved installation directions in appendix, added manual formatting
2407 Tue Jul 30 17:26:39 1991 John Gilmore (gnu at cygint.cygnus.com)
2409 * configure.in: Remove xm.h and tm.h even if we aren't linking
2410 new ones, so "./configure sun4; ./configure none" does the right
2411 thing. Assume that alldeps.mak and depend are already built in
2412 srcdir, and avoid running "make" (particularly "make depend",
2413 which involves "gcc") from inside configure. Build Makefile
2414 directly rather than building Makefile.conf first.
2415 * configure: Regenerate with above changes.
2416 * Makefile.in: Use $(BISON) to find bison. Roll VERSION
2417 to 3.98. Revise gdb.tar.Z procedure to produce a file
2418 called gdb-$(VERSION).tar.Z but which unpacks into a
2419 directory called "gdb". Move non-source files out of
2420 $(SFILES_SUBDIR). Pretty up alldeps.mak with comments.
2421 (depend): Don't try to do "gcc expread.y".
2422 (expread.o): Update dependencies by hand.
2424 Mon Jul 29 15:21:09 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
2427 Fixed a variety of small typos that prevented info from formatting
2428 cleanly; altered too-long heading for GPL Appendix, as discussed
2429 w/RMS; Changed date on cover to July 91.
2431 Fri Jul 26 13:20:02 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
2434 (1) Applied some fixes due to comments from Larry Breed (easier ones
2435 through chapsec 5.2)
2436 (2) Eliminated use of @footnote---had my doubts about it anyways, and
2437 it's broken in latest texinfo
2438 (3) Introduced *some* use of [] for optional arguments, where
2439 explanation is not simpler by listing cmd w arg and cmd w/out arg
2440 separately. Still not using @deffn.
2441 (4) Dropped in GPL-2. NOTE: one of GPL-2 or texinfo is broken; a
2442 couple of headings are too long. Need patches to texinfo or revision
2445 * Partial update to README (which still needs work for this
2446 release!): (1) use of configure corrected for new script,
2447 (2) "make gdb.dvi" and "make gdb.info" mentioned.
2449 Wed Jul 24 06:44:02 1991 John Gilmore (gnu at cygint.cygnus.com)
2451 * symtab.c (lookup_symbol): Don't complain right off about
2452 no debug symbols; use the misc function vector first.
2453 (list_symbols): Use misc function vector to find symbols
2454 that don't have debug info, and print them.
2455 (find_pc_symtab): Temporarily avoid fatal() when psymtab
2456 PC range doesn't match symtab PC range, as it does on the
2457 MIPS because our symtab reading isn't perfect.
2459 * dbxread.c (dbx_symfile_read): Make warning about
2460 "no debug symbols" slightly nicer.
2462 * source.c (select_source_symtab): If "main" symbol exists,
2463 but decode_line_spec can't find line info, don't just return
2464 a zero; try other source symtabs or give an error.
2466 * mipsread.c (parse_partial_symbols): Sort the psymtabs by
2467 their low addresses first, then rip through fixing high addrs.
2469 * ns32k-opcode.h (sfsr): Bugfix from Rune Nerg}rd,
2470 <runene@ifi.uio.no>.
2471 (NS32K_SVC_IMMED_OPERANDS): Reverse the #ifndef.
2473 Tue Jul 23 18:52:43 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
2475 * Minor, mostly mechanical, cleanup of doc subdir for clean
2476 makeinfo'ing and TeXing; also ensured gdb-all.texinfo (post-m4)
2477 and gdb.info (post- texinfo2 makeinfo) generated for distribution.
2479 Sun Jul 21 03:54:52 1991 John Gilmore (gnu at cygint.cygnus.com)
2481 Mostly MIPS and general symbol-reading fixups.
2483 * doc/gdbint.texinfo: Add documentation on symbol-reading
2486 * mipsread.c: Remove kludges around #include "ecoff.h".
2487 Remove redefinitions of a_magic, etc, no longer used.
2488 (parse_symbol, ): Convert "Internal:" printfs to complain()ts.
2489 Fix global overview comments to match symfile.c protocol.
2490 (mipscoff_new_init): Eliminate cur_hdr if we have one.
2491 (mipscoff_symfile_read): Eliminate unused code. Avoid
2492 sorting all the symtabs, when all we have read here is psymtabs.
2493 The symtabs are sorted as they are created anyway. Tell
2494 condense_misc_bunches whether we're mainline.
2495 (psymtab_to_symtab_1): Pass filename when recursing, to make
2496 stack trace more informative.
2497 (parse_partial_symbols): Assume cur_hdr as argument.
2498 (read_mips_symtab): Don't clobber cur_hdr, so it can be freed.
2499 Pass cur_hdr implicitly to parse_partial_symbols. Avoid checking
2500 the TYPE_NAME of char *, since that's done in symfile.c.
2501 (free_numargs, parse_symbol, add_symbol, add_block,
2502 shrink_linetable): Declare these fns void.
2503 (upgrade_type): Convert tree of if's to switch. Clean up
2504 bogus "off == 0" handling with a complaint. Avoid setting
2505 field bitpos and bitsize of array with lower and upper bounds.
2506 Check specified bitsize of elements against their actual type's
2507 bitsize, and complain if different. Complain about unknown
2509 (parse_fdr): Don't assume sizeof(char *) == sizeof (struct *).
2510 (psymtab_to_symtab_1): Print names of subsidiary files that
2511 are being read in. FIXME, we read far too many files. This code
2512 is not the problem, the problem is in parse_fdr where the psymtabs
2514 (cross_ref): Result should indicate that we used one aux entry
2515 normally, or two if we encountered a "next" entry. This used
2516 to leave the caller pointing at the wrong aux entry.
2517 (add_symbol): If overflowed cur_block, reallocate it larger,
2518 chase all pointers to it, and complain(), rather than clobber memory.
2519 (shrink_block): Use xrealloc rather than xmalloc-and-copy.
2520 (new_field): Only allocate one field initially, not two.
2521 Pull ++ out of macro argument. Simplify.
2522 (_initialize_mipsread): Avoid initialization of importd
2523 global_psymbols and static_psymbols.
2525 * symfile.c (psymtab_to_symtab): Depend on XXX_psymtab_to_symtab
2526 to properly set pst->symtab; avoid searching for it.
2527 (symfile_fns): Improve comments, add a FIXME.
2528 * dbxread.c: Update comments to reflect symfile protocol.
2529 (read_ofile_symtab, end_symtab): Return the symtab.
2530 (psymtab_to_symtab_1): Set pst->symtab.
2532 * coffread.c (coff_symfile_read): tell condense_misc_bunches
2533 whether we're mainline.
2535 * symfile.h (sym_fns): Remove unused sym_discard member.
2536 * coffread.c, mipsread.c, dbxread.c: Remove XXX_symfile_discard.
2538 * mtrace.c (mtrace): Take effect if mallwatch is set, even if
2539 the environment variable is not.
2540 * infcmd.c (finish_command): Use filtered printfs.
2541 * cplus-dem.c: Add struct tags to a few unnamed structs.
2542 * valops.c (value_coerce_array): Improve comments.
2543 * valprint.c (type_print_varspec_suffix): Print array size only
2544 if greater than zero.
2545 * m88k-tdep.c: Shift some lines left by one space, that had
2546 apparently been trashed at some point.
2547 * TODO: More things to do, a few got done.
2549 Thu Jul 18 22:46:05 1991 John Gilmore (gnu at cygint.cygnus.com)
2551 * symtab.h (LOC_EXTERNAL): Eliminate in favor of LOC_STATIC.
2552 (ldsymoff, ldsymlen, globals_offset, statics_offset): Improve
2554 * dbxread.c (read_dbx_symtab): LOC_EXTERNAL -> LOC_STATIC.
2555 * expread.y, findvar.c, symmisc.c: Ditto.
2556 * printcmd.c (address_info): Update printed forms of LOC_
2557 symbols. Elim LOC_EXTERNAL.
2558 (print_frame_args): Keep track of param stack offsets before
2559 re-looking up to find the local register param is kept in.
2561 * mipsread.c: Use <symconst.h> and <sym.h> rather than <syms.h>.
2562 Further integration of mipsread into gdb. Eliminate unused
2563 routines, duplicate declarations. Handle static symbols in
2564 psymtabs as well as external symbols. When reading symtabs,
2565 insert symbols into the correct block (global, static, or a local
2567 (read_mips_symtab, parse_partial_symbols): Don't pass useless
2569 (mipscoff_symfile_read): Don't call select_source_symtab.
2570 (parse_symbol): Use SYMBOL_VALUE_ADDRESS where appropriate,
2571 rather than SYMBOL_VALUE.
2572 (parse_external): Comment clobbering of top_stack.
2573 (parse_partial_symbols): Update comments. Allocate and parse
2574 static symbols as well as external symbols. FIXME, enum values
2575 are not handled in this pass, but should be. Inline new_psymbol.
2576 Use SYMBOL_VALUE_ADDRESS.
2577 (psymtab_to_symtab_1): Read symbols into global static block
2578 by default (until enter some function's local block context).
2579 (sort_blocks): Clean up STATIC_BLOCK as well as GLOBAL_BLOCK.
2580 (destroy_all_symtabs, new_psymbol): Eliminate, unused.
2582 * source.c (select_source_symtab): Select a source symtab
2583 from either the symtabs or, failing that, the psymtabs.
2584 (list_command): Update error message.
2585 (forward_search_command, reverse_search_command): Use getc, not
2586 fgetc, for speed. FIXME, add comment about buffers that die if
2587 overrun by long line.
2589 * values.c (unpack_field_as_long, modify_field): Avoid shifting
2590 by an entire word, which is not portable, if we have a 32-bit
2591 field. (Code in dbxread.c already turns such bitfields, if
2592 aligned, into ordinary ints, but fixing this will help for other
2593 symbol formats and for future changes.)
2594 * core.c (core_open): Handle ANSI const brain death.
2595 * utils.c (vprintf): Fix varargs typo.
2597 Sun Jul 14 00:42:53 1991 John Gilmore (gnu at cygint.cygnus.com)
2599 * findvar.c (find_var_value): Handle &function better.
2600 * TODO: Document work needed on &fn and &array.
2601 * printcmd.c (print_address_symbolic): New arg is the prefix
2602 to print if a name is printed.
2603 (print_address_demangle): Honor "set print address" now.
2604 Use new arg above to improve spacing of output.
2605 * valprint.c (val_print): When printing function pointers,
2606 print symbolic form too.
2607 * breakpoint.c (breakpoint_1): Use new print_address_symbolic.
2609 Mon Jul 8 19:02:46 1991 John Gilmore (gnu at cygint.cygnus.com)
2611 * core.c (memory_error): Reword error msg to mislead less.
2613 * mips-pinsn.c (print_insn_arg 'd'): Print $ with reg name.
2615 * mipsread.c (read_mips_symtab, read_the_mips_symtab,
2616 parse_partial_symbols): Use newer BFD internals (external_filehdr
2617 and external_aouthdr), byte-swap the fields that we care about
2618 before using them, and make the file header data local to
2619 read_the_mips_symtab rather than global.
2621 Sat Jul 6 01:34:15 1991 John Gilmore (gnu at cygint.cygnus.com)
2623 * ns32k-opcode.h (movmw, movmd): Fix opcodes. Bug fix
2624 from Rune Nerg}rd <runene@ifi.uio.no> on 5 Jul 1991.
2626 * main.c (command_line_input): Flush stdout and stderr
2627 before every call to readline. This reportedly fixes a bug
2628 that comes up in Sys V running emacs-gdb and/or xxgdb,
2629 when stdin/out are pipes or sockets.
2631 Thu Jul 4 14:47:06 1991 John Gilmore (gnu at cygint.cygnus.com)
2633 * configure.in, Makefile.in: Avoid rebuilding "depend" as much.
2634 Avoid declaring Makefile dependencies, because GNU Make stupidly
2635 tries to update it if we do.
2637 * coffread.c: Revise for minor changes to bfd internal coff
2640 * configure: If -template= is given a relative path, make it
2641 absolute before recurring in subdirectories.
2643 * configure, configure.in, Makefile.in: Install "configure" script
2644 as replacement for config.gdb.
2645 * config.gdb, Makefile.dist, Makefile.sdir: Remove
2646 * README: Update for configure, mostly. FIXME.
2648 * Add dec3100 as equivalent to littlemips. Indicate in all host &
2649 target config files that they are for the host. When the lines
2650 get copied into the Makefile, this makes it more obvious what's
2653 Mon Jun 24 23:49:07 1991 John Gilmore (gnu at cygint.cygnus.com)
2655 * sparc-opcode.h (trap opcodes): Avoid leading spaces or
2656 tabs, which end up in the disassembler output inadvertently.
2658 Wed May 29 23:01:03 1991 John Gilmore (gnu at cygint.cygnus.com)
2660 Make it compile cleanly in an ANSI GCC2 environment.
2662 * blockframe.c: <stdio.h>
2663 * cplus-dem.c: free takes a void *, ifdef __STDC__
2664 * dbxread.c (read_huge_number): avoid gcc2 bug hoisting calc of
2666 * defs.h (alloca): Avoid doing anything if alloca already def'd.
2667 * stddef.h, stdlib.h: Remove these files.
2668 * symtab.c: Avoid declaring qsort, close.
2669 * symfile.c: Avoid declaring close.
2670 * utils.c (vprintf): Declare "ap" arg as proper va_alist.
2671 * sparc-tdep.c: Avoid including lots of Sun-host-specific files.
2673 Assorted other changes.
2674 * dbxread.c: include "libaout.h", not "liba.out.h".
2675 * printcmd.c (print_frame_args): Set recurse properly for
2676 indentation of struct and array parameters.
2677 * valops.c (value_cast): Allow cast to void.
2678 * infrun.c (resume): If NO_SINGLE_STEP, call machine dependent
2679 single_step() in a target-independent fashion.
2680 * sparc-tdep.c (single_step): Don't call ptrace ourselves, just
2681 set up to be ready to continue. This makes us target independent.
2682 * infptrace.c (child_resume): Remove call to single_step; now
2683 can single step a SPARC target of any kind.
2685 Wed May 22 18:18:24 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
2687 * Makefile.dist, doc/gdb.texinfo, doc/*-m4.texinfo: split up GDB
2688 docn into separate sections---basically chapters, plus two loose
2689 pieces that can be configured to go in different places. This
2690 allows GNU m4 to preprocess the manual without coredumping.
2692 * Makefile.dist: tell TeX where to find texinfo.
2694 Mon May 20 12:15:04 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
2696 * Makefile.dist, doc/gdb.texinfo: respectively create, and use,
2697 the new target "rdl-apps.texinfo" which captures the Makefile
2698 variable that records where to find the Readline libraries.
2700 Sun May 19 05:36:59 1991 John Gilmore (gnu at cygint.cygnus.com)
2702 * tahoe-pinsn.c: #include "tahoe-opcode.h", not "opcode.h".
2703 * tm-tahoe.h (FIX_CALL_DUMMY): Ignore more parameters.
2704 * defs.h (const, volatile): Only define if not already defined.
2705 * Makefile.dist (gdb.tar.Z): Create doc subdir w/out CVS/RCS crud.
2707 * README: Update for release 3.95.
2708 * config.gdb: Don't create readline dir in subdir builds.
2709 * main.c: Include with "..." form for non-system include files,
2710 so "gcc -MM" for "make depend" works.
2711 Include readline files with "...h" rather than <readline/...h>.
2712 * mipsread.c: Include "ecoff.h" rather than "intel-coff.h".
2714 * coffread.c: Undo minor damage done by Rich Pixley. Use
2715 different internal and external representations of COFF
2716 data structures. Use new BFD routines for swapping them in and
2718 * symfile.c (free_named_symtabs): Avoid freeing file names that
2719 are null or empty. Old i960 tools seem to produce files that
2720 claim to have empty names, causing each successive file read
2721 to blow away the previous one.
2722 * sparc-xdep.c (deferred_stores): Repair minor damage by Rich.
2723 Move deferred_stores to top of file, but don't separate its
2724 #define's from its variable. Add commentary.
2725 * Makefile.dist: Fix Rich damage; undo "configure" changes in
2726 favor of keeping the (working) config.gdb. Move readline
2729 Fri May 17 12:49:56 1991 Per Bothner (via gnu at cygint.cygnus.com)
2731 * dbxread.c (read_struct_type): Try to handle g++ version 1 MI
2733 * infptrace.c (fetch_registers): no result, since now void.
2734 * tconfig/news: target depends on m68k-tdep too.
2736 Fri May 17 14:40:14 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
2738 * Makefile.dist: added readline/inc-*.texinfo to dependencies for
2741 * readline/inc-history.texinfo, readline/inc-readline.texinfo:
2742 applied various small fixes due to or inspired by RMS comments
2744 * doc/gdb.texinfo: finished using all RMS comments, save those for
2745 appendices on readline and cmd history (which are in other source
2748 Thu May 16 18:06:05 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
2750 * doc/gdb.texinfo: (1) Updated w/ref to RMS comments through
2751 chapter 9; (2) documented 'break' command's menu mode for
2752 overloaded names, in response to hgs problem report C++ p-31
2754 Wed May 15 11:02:48 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
2756 * doc/gdb.texinfo: (1) better introductory example; (2) more
2757 consistent use of @code, @samp, @file, @kbd throughout; small
2758 cleanups to first three nodes; (3) new "Contributors" node;
2759 (4) Appendix, Renamed Commands; (5) divert specialized startup
2760 instructions to "Targets" chapter for generic manuals, while
2761 leaving them up front for manuals specific to specialized
2762 environments; (6) apply fixes from RMS comments through chapter 4.
2764 * pretex.m4: modify explanatory text slightly (and redefine
2765 "regexp") to keep GNU m4 from complaining. (It still crashes
2766 later, but one step at a time...)
2768 Wed May 15 10:32:12 1991 John Gilmore (gnu at cygint.cygnus.com)
2770 * readline/readline.c (update_line): Avoid dereferencing a pointer
2771 before comparing it to its bounds. Saber caught this.
2772 (init_terminal_io): Don't set BC from the "pc=" termcap variable,
2773 and only set PC if tgetstr returned non-null. Saber caught this.
2775 Tue May 14 16:29:53 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)
2777 * Makefile.dist: put gdb.dvi stuff (updated to use M4 preprocessor
2778 stuff for config manual) here where it counts; updated
2779 to use new subdir structure (gdb/doc/).
2781 * Makefile: generated from above via
2785 * gdbint.texinfo: added instructions on generating gdb.info* files
2786 locally for release. These are ordinary info
2787 files, formatted from gdb.texinfo (via gdb-all.texinfo, see
2788 Makefile)---but due to use of texinfo 2, can't count on makeinfo
2789 to generate these, so we distribute them already formatted.
2791 * gdb.texinfo: included full Info node and menu crud (as generated
2792 by C-u M-x texinfo-master-menu using the texinfo-2 elisp code).
2794 * Makefile: updated "gdb.dvi" target to use M4 preprocessor;
2795 put in comments-for-future gdb.info target (one day makeinfo will
2798 Tue May 14 13:51:36 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)
2800 * gdb.texinfo: Updated to include new or old undocumented
2801 commands, at least the following (perhaps some others I forgot to
2802 record): info f, info float, info path, info program, info s, info
2803 set, info source, info terminal, info types, info user, set/show
2805 Also covered all recent GDB command renames for v4.
2807 Mon May 13 14:57:46 1991 John Gilmore (gnu at cygint.cygnus.com)
2809 * mipsread.c: Rather than keeping count of how many symtabs
2810 and psymtabs we have, for sorting purposes, count them when
2811 we need to sort. This fixes bug in rereading of symbol tables.
2813 Fri May 10 15:43:33 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)
2815 * infcmd.c: renamed "info path" to "show paths"
2816 * gdbrc.tex: documented above.
2818 Wed May 8 04:51:11 1991 John Gilmore (gnu at cygint.cygnus.com)
2820 * remote.c: Fix comments.
2821 * utils.c (error): Force out any pending wrap output.
2823 Sat May 4 11:11:07 1991 John Gilmore (gnu at cygint.cygnus.com)
2825 * Makefile.dist: Roll VERSION to 3.95.
2826 Fix up "saber_gdb" to work again.
2827 * saber.suppress: Update.
2829 * coffread.c, exec.c, infptrace.c, inftarg.c, remote.c, solib.c,
2830 symtab.h, target.c, target.h: Lint.
2831 * core.c: setup and select frame after reading shared libs,
2832 else reading shared libs will clobber them. Lint.
2833 * utils.c (error): Force out any buffered wrap text.
2835 Fri May 3 22:01:56 1991 John Gilmore (gnu at cygint.cygnus.com)
2837 * remote.c: Remove decls of memory_insert_breakpoint
2838 and memory_remove_breakpoint, no longer used. (Suggestion of
2841 * Makefile.dist: use ${subdir} in paths of BFD and LIBIBERTY,
2842 to make it easier to interface to "configure"'d libraries.
2844 Fri May 3 13:10:01 PDT 1991 Roland Pesch (pesch at fowanton.cygnus.com)
2846 * valprint.c: introduce "set p", "set pr", "show p" and "show pr" as
2847 aliases for set/show print.
2849 Thu May 2 11:22:02 1991 Jim Kingdon (kingdon at cygint.cygnus.com)

2875 {unpack_,value_as_}long (for now anyway).
2877 * m88k-tdep.c (get_saved_register): Make get_reg a dc_word_t (*)().
2878 (psr_register): Change return type to dc_word_t.
2880 * m88k-tdep.c (tdesc_read_function): Comment out call to ptrace.
2882 * m88k-tdep.c (get_saved_register): Add lvalp parameter.
2884 * gdbcore.h (write_memory): Don't prototype it.
2886 * tm-88k.h, m88k-tdep.c: Make stack_error, stack_jmp global.
2887 m88k-xdep.c: Don't mention stack_error.
2889 * {x,t}config/m88k ({X,T}DEPFILES): Add missing files.
2891 * mtrace.c: Don't typedef things like size_t, just #define them.
2893 * coffread.c [TDESC]: #if 0 out references to coffsyn.
2895 * symtab.h (struct symtab): Include EXTRA_SYMTAB_INFO.
2896 tm-88k.h: Define EXTRA_SYMTAB_INFO.
2898 * coffread.c [TDESC]: Include "tdesc.h" and make tdesc_handle
2899 dc_dcontext_t not int.
2901 * coffread.c [TDESC]: Use system include files not <intel-coff.h>.
2903 * coffread.c [TDESC]: Move setting of debug_info from
2904 coff_symfile_read to find_linenos and make it work with BFD.
2906 * cplus-dem.c [__STDC__]: Make x{m,re}alloc return void*.
2908 * signame.c: Cast const char* to char* when assigning to sys_siglist.
2910 * utils.c (strsave): Make arg const char* not char*.
2912 * infrun.c (wait_for_inferior) [SHIFT_INSN_REGS]: Use
2913 bpstat_explains_signal (stop_bpstat) not stop_breakpoint.
2915 * tm-88k.h (START_INFERIOR_HOOK): Make tdesc_handle a dc_handle_t.

3383 * symfile.c (clear_symtab_users_once, cashier_psymtab,
3384 free_named_symtabs): Move these routines from symmisc.c.
3385 * symmisc.c (same): same.
3386 (free_symtab): Make non-static.
3387 * symtab.h (free_symtab): Declare as exported void fn now.
3388 * dbxread.c (end_symtab, end_psymtab): Change comments.
3389 (initialize_dbxread): Call dbx_new_init() in case the first
3390 command is add-symbols.
3391 * target.c (dummy_target): Permit add_syms_addr_command.
3393 Sat Apr 13 14:46:07 1991 John Gilmore (gnu at cygint.cygnus.com)
3395 Permit symbols to be superseded when new symbol files have
3396 been read in, particularly for VxWorks.
3398 * dbxread.c (read_dbx_symtab): Allow N_SOL to cleanly take us back
3399 to the main file, as well as to include files. Also, put global
3400 functions into the global psymtab, to make "i fun" work.
3401 (end_psymtab): Free named symtabs and psymtabs for a file, once a
3402 new psymtab for it has been read.
3403 * coffread.c (end_psymtab): Free named symtabs and psymtabs for
3404 a file, once a new symtab has been read for it.
3405 * mipsread.c: FIXME. We need to do the same for MIPS, but it
3406 looks harder to determine the top-level block before it's been
3407 queued to the psymtab list.
3409 * symfile.c (symbol_file_add): Use filtered printing and wrap it.
3410 If we have wiped out any old symbol tables, clean up at end of
3412 (symbol_file_command): Don't reference symfile_fns if it's zero.
3414 * symtab.h (GLOBAL_BLOCK, STATIC_BLOCK, FIRST_LOCAL_BLOCK): New
3415 defines for the blocks of a blockvector that contain global and
3416 file-static symbols and the first of the smaller scope contours.
3417 * symtab.c (lookup_symbol, find_pc_symtab, find_pc_line,
3418 decode_line_1, make_symbol_completion_list): Use the above.
3419 * coffread.c (end_symtab, patch_opaque_types): Ditto.
3420 * dbxread.c (end_symtab): Ditto.
3421 * expread.y (block): Ditto.
3422 * mipsread.c (throughout): Ditto.
3423 * symmisc.c (free_named_symtabs): Ditto.
3425 * symtab.c (list_symbols): Process the first symbol of the
3426 static psymbols list.
3427 (types_info): Restore this function from its untimely #if 0.
3428 It's not perfect, but it is better than nothing.
3429 (_initialize_symtab): Restore "info types".
3431 Thu Apr 11 05:23:19 1991 John Gilmore (gnu at cygint.cygnus.com)
3433 * m68k-stub.c: Remote stub for 680x0's, created from
3434 rem-m68k.shar (which is removed).
3435 * nindy-share/{Makefile,Onindy.c,blout.h,env.h,nindy.c,ttyflush.c}:
3436 Remove RCS log stuff now that we use CVS and it blows our diffs.
3438 Wed Apr 10 14:18:06 1991 John Gilmore (gnu at cygint.cygnus.com)
3440 * symmisc.c (free_named_symtab): Make it work, in its current
3441 kludgy fashion. Change result to indicate if we blew away bkpts.
3442 * dbxread.c (end_symtab): Accumulate result from
3443 free_named_symtab and print warning if we blew user's state.
3444 * symfile.h: free_named_symtab now returns an int.
3446 Mon Apr 8 23:57:43 1991 John Gilmore (gnu at cygint.cygnus.com)
3448 * dbxread.c (dbx_symfile_read): Initialize psymbol list if this
3449 is the first symbol read, even if not mainline.
3450 (dbx_psymtab_to_symtab): symfile might be zero, cope.
3451 * exec.c (exec_ops): Add_syms_addr is valid in our tvec.
3452 (set_section_command): New command ("section xxx yyy" -- should
3453 be renamed to "set section xxx yyy" FIXME) which sets the
3454 base address of a section of the exec file, overriding the
3455 virtual address that BFD reports.
3457 Fri Apr 5 17:14:39 1991 John Gilmore (gnu at cygint.cygnus.com)
3459 * exec.c: Add add_syms_addr_command to exec_ops, so you can
3460 load symbols at any address while examining an exec file.
3462 Thu Apr 4 10:09:35 1991 John Gilmore (gnu at cygint.cygnus.com)
3464 * tm-i386v.h (FLOAT_INFO): Don't define it, since the code
3465 for printing the float info is host-dependent, not
3466 target-dependent. FIXME.
3467 * i386-pinsn.c: Move #includes to top, remove useless ones.
3468 * i386-tdep.c: Don't bother including <.../reg.h> since we
3469 don't use it (and it doesn't exist on host systems).
3471 * ieee-float.c (ieee_extended_to_double): Convert NaN to Inf.
3472 Convert negative numbers properly.
3473 (ieee_test): Make numbers really random; fix format arg.
3475 * infcmd.c (attach_command, detach_command): Don't repeat on CR.
3476 * core.c (core_detach): Unpush core_ops, which might not be on
3477 top. We used to just pop the top, which broke things. Don't
3478 need dont_repeat() any more.
3479 (core_file_command): Psst! Don't repeat it.
3480 * remote-nindy.c (nindy_detach): Don't need dont_repeat() now.
3481 * expprint.c (print_subexp): Avoid switch fallthru on
3482 BINOP_ASSIGN_MODIFY, so we can print += and such.
3483 * frame.h: Fix typo.
3484 * inflow.c (kill_command): After killing inferior, print our
3485 current frame in the core file, if we have one.
3486 (generic_mourn_inferior): When inferior dies, either select
3487 the current frame (in the new target, e.g. core file), or
3488 set both the current and selected frames to NULL.
3490 Changes from Peter Schauer.
3492 * infptrace.c: Avoid <sys/ptrace.h> on USG.
3494 * Make all file names fit in 14 characters (sigh and damn!):
3495 mv hp300hpux-xdep.c hp300ux-xdep.c
3496 mv symmetry-xdep.c symm-xdep.c
3497 mv symmetry-tdep.c symm-tdep.c
3498 mv convex-opcode.h convx-opcode.h
3499 mv tm-vxworks960.h tm-vx960.h
3500 mv tm-vxworks68.h tm-vx68.h
3501 mv Makefile.srcdir Makefile.sdir
3502 mv gdb-int.texinfo gdbint.texinfo
3503 mv remote-sa.m68k.shar rem-m68k.shar
3504 mv remote-multi.shar rem-multi.shar
3505 * Makefile.dist, README, config.gdb, convex-pinsn.c,
3506 tconfig/symmetry, tconfig/vxworks960, tconfig/vxworks68,
3507 xconfig/hp300hpux, xconfig/symmetry: Change names to shorter
3510 * command.c (user_info_1, user_info): New command for listing
3511 the user-defined commands.
3513 Wed Apr 3 15:00:26 1991 John Gilmore (gnu at cygint.cygnus.com)
3515 * dbxread.c (really_free_pendings): Clear file_symbols
3516 and global_symbols after freeing them; otherwise, running
3517 this function twice (if it appears twice on the cleanup
3518 chain), we try to free things twice.
3520 * dbxread.c (read_dbx_symtab): Calculate end_of_text_addr
3521 based on text_addr (the address of text in core), not on addr (the
3522 offset between text in the .o file and in core). This change
3523 is from Peter Schauer.
3525 * main.c: Define ALL_CLEANUPS as a cast of zero.
3526 (return_to_top_level): Use it.
3527 (main): Do all cleanups after each command run as part
3528 of the gdb startup sequence. Also do all cleanups before
3529 entering the command loop, and every time we exit the command
3530 loop and reenter. Before, the cleanups from the startup sequence
3531 were being left undone until the first error!
3532 (command_loop): Rename do_nothing cleanup to command_loop_marker
3533 so we can see it easily when examining the cleanup chain.
3534 (init_signals): Add another do_nothing for signal handling.
3535 (quit_command): Only try to kill target if it has execution.
3536 Problems in the target stack got us into a state where
3537 inferior_pid was nonzero but none of the targets had execution.
3538 In this state you couldn't exit gdb.
3540 * dbxread.c: Two changes from Peter Schauer.
3541 (echo_command): Fflush output after an echo command.
3542 (show_history): Pass all args to cmd_show_list.
3544 * utils.c (init_malloc): Call mtrace to turn on tracing
3545 if the environment variable MALLOC_TRACE is set to a file name.
3546 * mtrace.c: Add source file which provides a log of every malloc,
3547 free, and realloc to a trace file.
3548 * mtrace.awk: Add source file which analyzes the trace file.
3549 * Makefile.dist (GNU_MALLOC, MALLOCSRC): Add mtrace.{c,o,awk}.
3550 (VERSION): Roll to 3.94.3.
3552 * breakpoint.c (breakpoint_1): Add a space to "i watch" output.
3553 (check_duplicates): Don't bother with watchpoints.
3554 (set_raw_breakpoint): Comment about danger of this routine.
3555 (watch_command): Parse and eval all args before calling
3558 * solib.c (find_solib): Avoid error in referencing memory to
3559 see if any more shared libraries have been added. This is
3560 particularly useful if the target has terminated. Bug reported
3563 Changes from Peter Schauer <pesrem@regent.e-technik.tu-muenchen.de>
3564 in bringing up 3.94.2 on the Sun-3.
3566 * Makefile.dist: Include CFLAGS in rule for cplus-dem.o.
3567 * breakpoint.c (enable_breakpoint): Check for valid watchpoint
3568 expression (in scope) before reenabling watchpoint.
3569 * signame.c (init_sigs): Add missing declaration of i, fix
3570 sys_siglist declaration.
3571 * source.c (list_command): Fixed range computation to use
3573 * stack.c (backtrace_command): Do not allow command if target has
3574 no stack, print informative error message.
3575 * target.c (target_command): Do not write into command line
3576 because this fails if the target command is used in a user defined
3577 command. [This change was enhanced by gnu to support any-
3578 unique-prefix matching on target names.]
3579 * valops.c (value_struct_elt): Avoid infinite loop on an
3580 erroneous attempt to print the member of function (try p main.p).
3582 Mon Apr 1 17:05:45 1991 John Gilmore (gnu at cygint.cygnus.com)
3584 * expread.y (name_no_typename): Avoid reduce/reduce errors
3585 caused by ambiguity in handling NAME_OR_INT and NAME_OR_UINT.
3586 Since the GDB parser really doesn't use name_no_typename in a
3587 name-only context, the parser can't tell the diff between
3588 names and numbers here. Avoid allowing a name_no_typename
3589 to be a NAME_OR_*INT to resolve the conflict.
3591 Sun Mar 31 20:12:07 1991 John Gilmore (gnu at cygint.cygnus.com)
3593 Bugfixes from Mark Fox (markf@wrs.com) (test=testField.c):
3595 * valprint.c (val_print_fields): bitfield printing didn't handle
3596 byte order. Indirect through a few more fns to cope.
3598 * values.c (modify_field): also cope with byte order.
3600 Sat Mar 23 10:02:21 1991 John Gilmore (gnu at cygint.cygnus.com)
3602 Cleanup for release 3.94.2:
3604 * Makefile.dist: Pull REMOTE_OBS. Fix saber includes for BFD
3605 include files. Roll version to 3.94.2.
3607 * coffread.c (init_stringtab): Read length into unsigned char
3608 array before swapping; don't assume 32-bit longs.
3610 * target.c (target_info): Don't bother with get_sym_file, just use
3611 the symfile global variable.
3612 * symtab.h, symfile.c (get_sym_file): Delete it.
3614 * dbxread.c (dbx_symfile_init): Don't depend on long == 4 bytes.
3615 (define_symbol): Set symbol line number to 0 if not gcc-compiled.
3616 (read_type): Replace one more error() with complain().
3618 * mipsread.c (parse_partial_symbols): Replace printf with complain.
3620 * i960-tdep.c: Fix copyright attribution.
3622 * config.gdb: Quote all backquotes in doublequotes. You can
3623 quote me on that. BSD 4.4 shell found this one.
3625 * infptrace.c (throughout): The third argument to ptrace is an
3628 * infrun.c (wait_for_inferior): When program has terminated, we
3629 have to call target_terminal_ours before we pop that target off
3630 the stack (e.g. before a call to target_kill or
3631 target_mourn_inferior). This fixes problem where a program
3632 terminates, then GDB stops for (tty output) and you have to type
3633 "fg" to the shell to resume it. FIXME: This code for what to
3634 do after termination really should be in normal_stop instead.
3636 * gdbcore.h (read_memory_check): Change declaration; it changed
3639 * terminal.h: Include <sgtty.h> before <sys/ioctl.h>, since in BSD
3640 4.4 prereleases, this avoids a bug in their sgtty compatability
3642 * remote.c: Use terminal.h rather than hand-rolling the same.
3644 * signame.c, signame.h (psignal): Arg is unsigned, not int.
3645 * utils.c (strsave, strstr): Fix arg types.
3646 * valprint.c (val_print): lint
3648 MIPS symbol table support from Per Bothner:
3650 * symfile.c (symtab_fns): Remove initializer table that needs to
3651 be hacked for each new symbol file format supported.
3652 (add_symtab_fns): New function, chains symbol table
3653 handlers into the global list.
3654 (symfile_init): Search this list.
3655 * symfile.h: Add next pointer, declare add_symtab_fns.
3656 * coffread.c (_initialize_coffread): Call add_symtab_fns.
3657 * dbxread.c (_initialize_dbxread): Call add_symtab_fns.
3659 * mipsread.c (psymtab_to_symtab_1): return void instead of (struct
3660 symbol *). Thus, we no longer need the hack to trash
3661 pst->filename. Good, since that hack confused code in symfile.c!
3663 (reorder_symtabs, destroy_all_symtabs): Removed static
3664 all_symtabs, which was used to qsort symtabs in reorder_symtabs.
3665 Instead, the latter now uses a temporary array (stack-allocated
3666 from an obstack, and then freed).
3668 (parse_symbol): Added a hack to fix up BLOCK_{START,END} if they
3669 haven't been set in the outermost stBlock of a procedure. This was
3670 a problem with f77 binaries on Ultrix 4.?.
3672 (new_symtab, new_symbol, new_type): Continue changing code to use
3673 obstacks more and otherwise conform to dbxread internal style.
3674 Made the free_code of symtabs be free_linetable (as in dbxread)
3675 instead of free_contents. This implies memory leaks when reading
3676 a new symbol table, until the conversion is finished. Did change
3677 (struct symbol) and (struct type) to be allocated on the
3678 symbol_obstack. Blocks and blockvectors are among the things
3681 * mipsread.c (parse_partial_symbols, parse_fdr): It hasn't been
3682 tested much, but it solved one problem (reported by Meissner), and
3683 cleans up some other things. The problem happened when an
3684 included file contains actual code (functions) and not just
3685 definitions. The mips coff is a little inconvenient there, since
3686 it may cause a procedure to be mapped to the wrong psymtab.
3688 * mips-tdep.c (heuristic_proc_desc): Minor cleanup.
3689 * mips-xdep.c (fetch_core_registers): Minor cleanup. FIXME,
3690 this will need work for the new core paradigm.
3692 Opcode patches from the net:
3694 * mips-opcode.h: fix incorrect disassembly of the mfc1, cfc1, and
3695 ctc1 instructions. Also, the cvt.d.w and cvt.s.w instructions were
3696 missing altogether - they are added here. From Bruce Bauman.
3697 * mips-opcode.h: The low mask for C0 instructions was too small.
3698 From Garrett Lau. I modified the fix to check the entire 32-bit
3701 * ns32k-opcode.h: Fix opcodes for deiw and deid. From Bruce
3704 Thu Mar 21 12:56:46 1991 John Gilmore (gnu at cygint.cygnus.com)
3706 Roll in changes from Per Bothner (Tue, 25 Sep 90 11:11:04):
3708 * dbxread.c (read_type): Pointer subtraction (value_sub in
3709 valarith.c) sometimes failed because the types of the
3710 pointers being subtracted were not identical.
3711 These differed because dbxread.c was allocating pointer types
3712 using dbx_alloc_type+smash_to_pointer_type instead of
3713 lookup_pointer_type. I failed to find a justification for the
3714 former, so I changed it to use the latter. Similarly, I
3715 replaced smash_to_function_type by lookup_function_type,
3716 and smash_to_reference_type by lookup_reference_type.
3718 * mipsread.c (parse_symbol, upgrade_type, parse_procedure,
3719 _initialize_mipsread): corresponding changes.
3721 * symtab.c (smash_to_{pointer,reference,function}_type): eliminate.
3723 * source.c (mod_path): Do tilde_expand on each component of the path,
3724 rather than on the (list of) paths as a whole.
3725 (print_source_lines): Set first_line_listed in addition to
3726 current_source_symtab and current_source_line. If the source was
3727 not findable, after a "dir" command to fix the problem,
3728 a "list" would get the wrong lines.
3730 While I was there... (gnu):
3732 * dbxread.c (read_type): Change error to complaint.
3734 Thu Mar 21 12:56:46 1991 John Gilmore (gnu at cygint.cygnus.com)
3736 First attempt at detailed understanding of symbol table memory alloc.
3738 * dbxread.c (dbx_symfile_read): Free our string table if we
3739 aren't the mainline. Free the "info" struct since we're done with
3741 (init_psymbol_list): Free any previously allocated psymbol lists.
3742 (): FIXME: Should realloc-down the psymbol lists when done reading
3743 the main symbol file?
3745 * symmisc.c (free_symtab): Free fullname field too.
3747 * xm-hp300hpux.h (USG): #undef then #define so Makefile can -D.
3748 (REGISTER_ADDR): Make result type unsigned int.
3750 * xconfig/{i386*,hp300hpux,altosgas,altos}: All config files that
3751 define REGEX must also define REGEX1 (its dependency).
3753 Tue Mar 19 21:28:57 1991 John Gilmore (gnu at cygint.cygnus.com)
3755 * tconfig/i960: No longer works, points you at vxworks960 or
3758 * xgdb.c, XGDB-README: Remove file. Users can get the much
3760 * Makefile.dist: Remove all trace of xgdb.
3762 * breakpoint.c (breakpoint_1): Pass demangle arg to
3763 print_address_symbolic.
3764 (clear_breakpoints): Remove unused function.
3765 (breakpoint_re_set_one): Guts of breakpoint_re_set.
3766 (breakpoint_re_set): Use catch_errors to do them all anyway.
3768 * gdb-int.texinfo (Host versus Target): Add section on what is
3769 a "host" feature versus what is a "target" feature.
3771 * infcmd.c (path_command, path_info): Handle the PATH variable
3772 (object search path) as conveniently as the source search path.
3773 * environ.c (set_in_environ): Set some vars in GDB's environment,
3774 in addition to the child's. PATH, G960BASE, G960BIN for starters.
3775 * source.c (mod_path): New function, from guts of
3776 directory_command, modifies a path. Used by path_command.
3777 (directory_command): Call it.
3778 * defs.h (strsave): Declare.
3780 * utils.c (sevenbit_strings): Add new printing option.
3781 (printchar): Use it.
3782 (strsave): Provide this handy helper routine.
3783 (set_width_command): Rename set_screen_width_command.
3784 (_initialize_utils): "set screen-width" => "set width";
3785 "set screen-height" => "set height"; add sevenbit-strings.
3787 * infcmd.c (do_registers_info): Print floating point registers
3788 in raw hex as well as float format, regardless of whether it is
3789 a "virtual" convertible register.
3790 * tm-sparc.h (PRINT_REGISTER_HOOK): Print every pair of float
3791 regs as a double, just in case it's being used that way.
3792 * values.c (unpack_long): Comment on array/function coercion.
3793 (unpack_double): Argument is in target byte order now. For
3794 integer arguments, just call unpack_long and float the result.
3795 * m68k-tdep.c: include defs.h for "const" handling.
3796 * remote-nindy.c: Use ieee-float stuff.
3797 (nindy_fetch_registers): Unpack double regs to host double, then
3799 (nindy_store_registers): Pack extendeds to host double, flip
3800 around by misusing unpack_double, send as target double.
3802 * tm-vxworks68.h (FRAME_CHAIN): Handle current frame pointer of
3803 zero, as when stopped at the first instruction of a process.
3805 * blockframe.c: Fix filename in comment (param.h => tm.h).
3806 * sparc-tdep.c (skip_prologue): More explicit nudging comments.
3807 * tm-68k.h: Fix typos.
3809 Fri Mar 15 01:09:34 1991 John Gilmore (gnu at cygint.cygnus.com)
3811 Changes from a bringup on the DEC Vax under Ultrix 4.0.
3813 * coredep.c (fetch_core_registers): Pass end-address of register
3814 section to register_addr as expected. Don't call supply_register
3815 if we'd just pass it garbage.
3817 * dbxread.c (read_dbx_symtab): Skip N_NSYMS on Ultrix.
3819 * exec.c (xfer_memory): Use boolean xfer_fn result, not int.
3821 * target.c (push_target, target_info): Cast enums to int for < or
3824 * stack.c (print_frame_info): Identify source file & line
3825 even if we can't print it.
3827 * xm-vax.h (MISSING_VPRINTF): No longer missing in Ultrix V4.0.
3829 Sat Mar 9 10:08:20 1991 John Gilmore (gnu at cygint.cygnus.com)
3831 Clean up IEEE floating point support.
3833 * ieee-float.h: New file.
3834 * ieee-float.c: Write real routines to convert between host
3835 doubles and various target IEEE extendeds.
3836 * m68k-xdep.c: Eliminate assembler code for extended floats.
3837 * xconfig/{3b1,altos,altosgas,hp300bsd,isi,news,news1000,sun2os3,
3838 sun2os4,sun3,sun3os3,sun3os4}: Eliminate use of m68k-xdep.o.
3839 * tm-i960.h, tm-68k.h (REGISTER_CONVERT_TO_VIRTUAL,
3840 REGISTER_CONVERT_TO_RAW): Use ieee_extended_to_double and
3841 double_to_ieee_extended.
3842 * i960-tdep.c: Define ext_format_i960.
3843 * m68k-tdep.c: Define ext_format_68881.
3844 * sparc-tdep.c: Define ext_format_sparc, though unused.
3845 * Makefile.dist (HFILES): Add ieee-float.h.
3846 * inftarg.c: #include "ieee-float.h" for the REGISTER_CONVERT
3849 Obsolete the "coffstrip" program in favor of using BFD's strip.
3851 * nindy-share/coffstrip.c: Remove file.
3852 * nindy-share/nindy.c (coffstrip): Routine to run bfd_strip.
3853 * Makefile.dist: Remove references to nindy-share/coffstrip.c.
3854 * tconfig/nindy960: Remove reference to coffstrip.o.
3856 * Makefile.dist: Roll version number to 3.94.1 (not yet final).
3858 Wed Mar 6 09:56:45 1991 John Gilmore (gnu at cygint.cygnus.com)
3860 * symfile.h: Add symfile_bfd, common between dbxread and coffread.
3861 * dbxread.c: Remove static symfile_bfd.
3862 * infcmd.c (do_registers_info): Add PRINT_REGISTER_HOOK, though
3864 * inftarg.c (child_detach): Pop the child_ops vector if the
3865 detach is successful.
3866 * remote-nindy.c (nindy_create_inferior): Don't push a new
3867 nindy_ops since nindy uses the same one for execution and memory
3869 * core.c (core_ops): Use child_attach and child_create_inferior
3870 rather than default attach and create_inferior functions.
3872 Handle floating point registers in core files.
3874 * sparc-xdep.c (fetch_core_registers): Rewrite for float support.
3875 * sun3-xdep.c (fetch_core_registers): Rewrite for float support.
3876 This version untested since BFD doesn't yet support sun3 core
3878 * hp300hpux-xdep.c: Rewrite fetch_core_registers to new calling
3879 conventions. Fix comments and style. This version has not
3880 been compiled yet, since we have no HP inhouse.
3881 * core.c (get_core_registers): Look for two sections, ".reg"
3882 and ".reg2", and pass both to fetch_core_registers sequentially.
3884 Revise directory path yet again.
3886 * source.c (forget_cached_source_info): Not static any more.
3887 (init_source_path): New default source path is "$cdir:$cwd".
3888 (dir_command): Handle variable arguments ($cdir, $cwd).
3889 (source_info): Print "Compilation directory" rather than
3890 "Originally compiled in" to remind people of $cdir.
3891 (openp): If the path contains $cwd, use current directory.
3892 (open_source_file): If compilation directory is known, replace
3893 first $cdir in path with the compilation directory.
3894 (print_source_lines): Even if we can't print the lines, set the
3895 current symtab and line for future commands like "info source" or
3896 "breakpoint". Also, error message now contains the file name,
3897 line number, and file access error message.
3898 (_initialize_source): Fix help text to describe changes.
3899 * main.c (cd_command): Forget cached source info when we chdir.
3900 * utils.c (strstr): Add simple implementation.
3902 Tue Mar 5 01:41:40 1991 John Gilmore (gnu at fowanton.cygnus.com)
3904 * coffread.c (read_one_sym, init_linetable, init_stringtab):
3905 Byte-swap COFF symbol tables if necessary when reading them in.
3906 Use complain() to replace error message in one spot. Needs
3907 corresponding change in bfd/coff-code.h to make some symbol
3908 swapping routines non-static.
3910 Mon Mar 4 00:53:40 1991 John Gilmore (gnu at cygint.cygnus.com)
3912 Merge changes from Eirik Fuller, for UTek.
3914 * defs.h (errno): Add declaration.
3915 * altos-xdep.c, arm-xdep.c, convex-xdep.c, gould-xdep.c,
3916 hp300hpux-xdep.c, infrun.c, inflow.c, infptrace.c, i386-tdep.c,
3917 i386-xdep.c, pyr-xdep.c, mips-xdep.c, remote-eb.c, remote-nindy.c,
3918 remote-vx.c, source.c, standalone.c, stuff.c, sun386-xdep.c,
3919 symmetry-tdep.c, symmetry-xdep.c, umax-xdep.c, utils.c: Eliminate
3920 declarations of errno.
3922 * remote-eb.c: Define B19200 and B38400 as EXTA and EXTB.
3924 * remote-vx.c: Include <sys/time.h> for UTek; Sun gets it via
3925 <rpc/rpc.h> and <rpc/types.h>.
3927 Sat Mar 2 15:47:55 1991 John Gilmore (gnu at cygint.cygnus.com)
3929 * i960-tdep.c (examine_prologue): Add new argument limit,
3930 which stops the scan at the end of the prologue, or at the PC.
3931 This fixes a problem where it walks down into the code for the
3932 user's statements if that code looks like function prologues.
3933 Mark Fox and I have been bouncing this code back and forth, making
3934 small changes to it. Callers changed to match.
3936 Tue Feb 26 01:47:07 1991 Cygnus John Gilmore (cygnus at yuba)
3938 Cleanup for gdb-3.94 release final:
3940 * Makefile.dist: Remove remote-vx.c, remote-nindy.c, and all
3941 the .c files from vx-share and nindy-share, from the various
3942 macros, since they are not found via ALLDEPFILES.
3943 (SFILES): Add tm-i960.h.
3944 (alldeps.mak rule): Break out ALLDEPFILES_MAINDIR and
3945 ALLDEPFILES_SUBDIR. List all the nindy and vxworks subdir files
3947 (TAGFILES_MAINDIR): Change ALLDEPFILES to ALLDEPFILES_MAINDIR.
3948 (gdb.tar.Z): Use ALLDEPFILES_SUBDIR as well as SFILES_SUBDIR.
3950 Mon Feb 25 16:02:35 1991 Cygnus John Gilmore (cygnus at oldman)
3952 * am29k-tdep.c: Add contribution line.
3953 (examine_prologue): Cache information about function prologues in
3954 the misc-function-vector to avoid lots of references over the
3955 serial line while examining instructions.
3957 * core.c (core_close): New function made from cleanup_core.
3959 * core.c, exec.c, inftarg.c, remote-eb.c, remote-nindy.c,
3960 remote-vx.c, remote.c, target.c, target.h,
3961 Update target_ops vector to add attach, close, and load entries.
3962 Use add_syms_addr_command, not add_file_addr_command, for
3963 add_file. Break out close routine from existing code.
3965 * dbxread.c (really_free_pendings): Don't free pending_blocks;
3966 they are in an obstack.
3967 (read_dbx_symtab): Relocate end_of_text_addr in the psymtab.
3969 (define_symbol): Add symbol type parameter; change callers;
3970 pass type parameter to DBX_PARM_SYMBOL_CLASS macro to allow
3971 it to influence the symbol class on the i960.
3972 (define_symbol): Swap LOC_CONST's into target byte order.
3974 * exec.c (exec_close): New function.
3975 (exec_file_command): Call it.
3977 * findvar.c (read_relative_register_raw_bytes): Doc byte order,
3978 Fix byte order of frame pointer.
3979 (read_var_value): Result of 0 if var's value can't be found,
3980 e.g. missing FRAME_ARGS_ADDRESS. Byte-swap LOC_CONST and
3981 LOC_LABEL values to target order. Add LOC_LOCAL_ARG.
3982 (locate_var_value): Use read_var_value and use its lazy address
3983 as the location of the var's value. Lint.
3985 * i960-pinsn.c (next_insn): Add routine from vxgdb for scanning
3988 * i960-tdep.c (arg_address, i960_frame_find_saved_regs): Remove
3989 obsolete Intel versions in favor of vxgdb versions.
3990 (check_host, byteswap, byteswap_val, reorder_val): Eliminate
3991 code dealing with byte order of values, which Intel did in host byte
3992 order rather than gdb-4's target byte order.
3993 (i960_frame_chain_valid): Move to nindy-tdep.c.
3994 (examine_prologue, skip_prologue, frame_find_saved_regs,
3995 frame_args_address, leafproc_return, saved_pc_after_call,
3996 pop_frame): Add vxgdb versions from Mark Fox.
3997 (examine_prologue, frame_struct_result_address): Add code
3998 to deal with the saved value of G13 (struct return address
4000 (frame_args_address): Modify Mark's version to prefer the
4001 saved value over the current value in the topmost frame.
4002 Cache result in the frame info to avoid performance hair in
4004 (print_fault): Add gdb960 code for printing faults.
4005 (_initialize_i960): Actually call check_host.
4007 * ieee-float.c (ieee_extended_to_double, ieee_double_to_extended):
4008 add stub routines. FIXME, these currently just return zero!
4010 * infcmd.c (program_info): Use PRINT_RANDOM_SIGNAL.
4011 (attach_command): Call target_attach, not target_open, now.
4013 * infrun.c (normal_stop): Make global, not static, for vx_attach.
4014 (child_attach): Rename from child_open.
4015 (wait_for_inferior): Use PRINT_RANDOM_SIGNAL. If stop_pc is zero,
4016 don't confuse it with a zero step_resume_break_address.
4018 * inftarg.c (child_detach): Eliminate inferior_pid test.
4019 (child_files_info): Clean up message a bit.
4020 (child_ops): Use child_attach, not child_open, to attach.
4022 * mem-break.c: #ifdef out the whole file if BREAKPOINT is not
4023 set (e.g. on VxWorks or NINDY). Move read_memory_nobpt from
4024 findvar.c to here, since it depends on the contents of the
4025 shadow_contents of breakpoints, but keep if #if 0 since it is
4028 * nindy-tdep.c: New file, contains nindy_frame_chain_valid, moved
4031 * printcmd.c (address_info): Handle LOC_LOCAL_ARG. Lint.
4032 (ptype_command, display_command): Eliminate have_inferior_p and
4033 have_core_file_p in favor of target_has_stack or
4034 target_has_execution.
4035 (print_frame_args): Handle LOC_LOCAL_ARG. Eliminate duplicate
4036 code for actually finding the values of arguments, though we still
4037 keep track of the maximum stack offset for use in printing unnamed
4038 arguments. Handle missing FRAME_ARGS_ADDRESS.
4040 * remote-nindy.c (i960_print_fault): Move to i960-tdep.c.
4041 (struct nindy_regs): Define registers passed to/from nindy.
4042 (nindy_fetch_registers, nindy_store-registers): Translate between
4043 nindy and GDB formats for the registers.
4044 (dcache_init): Statically allocate the cache, since it was being
4045 allocated by a malloc that was never freed anyway.
4046 (nindy_create_inferior): Error, not core dump, if no exec file.
4047 (nindy_before_main_loop): Use target_load, not target_add_file.
4049 * remote-vx.c (net_load): Specify large timeout for load
4050 requests. Allow user to break out with INTERRUPT.
4051 (net_break): Remove useless code, clean up. Change callers.
4052 (parse-args, skip_white_space, find_white_space): Clean up arg
4053 parsing to cope with quoted strings.
4054 (net_wait, net_quit): Never call error, just return status.
4055 (vx_read_register, vx_write_register): Cleanup status checking.
4056 #ifdef the code based on which CPU we are using (960 or 68k),
4057 FIXME, this should be completely general but it isn't yet.
4058 (vx_xfer_memory, vx_resume): Cleanup status checking.
4059 (vx_run_files_info): Improve message.
4060 (vx_load_command): Renamed from vx_add_file_command. Allow load
4062 (net_ptrace): Remove unused routine.
4063 (vx_wait): Adopt code from vxgdb960 to cope with broken
4064 connections to target machine and prompt to disconnect. Remove
4065 debug printouts. Map some EVENT_'s to SIGnals.
4066 (add_symbol_stub, vx_open): Print names of object files we found,
4067 and "ok" if we read their symbols OK. Clarify output in general.
4068 (vx_attach, vx_detach, vx_kill): Add these commands.
4069 (vx_convert_from_virtual, vx_convert_to_virtual): Simplify.
4070 (vx_run_ops): Turn off all_mem, to avoid spurious msg in the
4071 "info files" output, and create_inferior, since we already have
4074 * stack.c (frame_info): Replace Frame_unknown with 0.
4075 (print_frame_arg_vars): Handle LOC_LOCAL_ARG.
4076 (return_command): Pop until the PC matches as well as the FP,
4077 so it works even if the FP is shared with another function,
4078 as in "frameless" or "leaf" procedures.
4080 * symfile.c (load_command): renamed from add_file_target_command.
4081 (add_syms_addr_command): renamed from add_file_addr_command.
4082 (add_syms_command): Stub to call target_add_syms.
4083 (_initialize_symfile): Change command names and descriptions,
4084 add-file => add-syms, and load from alias to its own command.
4086 * target.c (kill_or_be_killed, maybe_kill_then_attach,
4087 maybe_kill_then_create_inferior): Default for attempts to start
4088 a process, if one is already running, is to ask about killing
4089 it and retry if yes.
4090 (upstack_create_inferior): #if-0 it, strata obsolete it.
4091 (push_target, unpush_target, pop_target): to_close() a target
4092 before unstacking it.
4093 (target_info): Renamed from target_files_info.
4094 (_initialize_targets): Rename "i files" as "i target", accessible
4097 * target.h: Improve comments about the target_ vectored routines.
4099 * tm-i960.h: Remove NINDY-specific stuff to tm-nindy960.h.
4100 Convert commenting style to standard GNU style.
4101 (DBX_PARM_SYMBOL_CLASS): allow LOC_LOCAL_ARG's to be recognized.
4102 (SKIP_PROLOGUE): No longer a no-op.
4103 (SAVED_PC_AFTER_CALL): Now handles leaf procedures.
4104 (*_REGNUM): Sort register numbers.
4105 (REGISTER_BYTES, REGISTER_BYTE, REGISTER_RAW_SIZE,
4106 MAX_REGISTER_RAW_SIZE, REGISTER_CONVERTIBLE,
4107 REGISTER_CONVERT_TO_VIRTUAL, REGISTER_CONVERT_TO_RAW): Float regs
4108 are now 10 byte extendeds, not 8 byte doubles.
4109 (FRAME_CHAIN_VALID): Make this config-dependent, since it differs
4110 for nindy versus vxworks targets. FIXME, this should possibly go
4111 in the target vector.
4112 (EXTRA_FRAME_INFO, INIT_EXTRA_FRAME_INFO): Cache both
4113 frame_saved_regs and arg pointer with each frame.
4114 (FRAMELESS_FUNCTION_INVOCATION): New leafproc support.
4115 (FRAME_ARGS_ADDRESS): Use cached result.
4116 (FRAME_ARGS_ADDRESS_CORRECT): New, avoids g14 guessing.
4117 (FRAME_FIND_SAVED_REGS): Change arg to subsidiary fn.
4118 (PRINT_RAMDON_SIGNAL): Call print_fault.
4119 (POP_FRAME): Now works.
4121 * tm-nindy960.h: Break this off tm-i960.h. NINDY-specific
4122 option parsing and startup; STACK_END_ADDR, FRAME_CHAIN_VALID,
4123 BREAKPOINT, and DECR_PC_AFTER_BREAK are here.
4124 (ADDITIONAL_OPTION_HANDLER): use target_load, not
4127 * tm-vxworks960.h: Break this off tm-i960.h. VxGDB specific
4128 startup; DECR_PC_AFTER_BREAK, and FRAME_CHAIN_VALID are here.
4130 * valarith.c (value_subscripted_rvalue): Avoid handling
4131 floats and doubles specially; it gave alignment errors. Lint.
4133 * valops.c (value_of_variable, value_of_this): Error if unknown
4136 * valprint.c (print_floating): Bcopy rather than pointer-deref,
4137 to avoid alignment problems.
4138 (value_print): Handle unknown value address.
4139 (cplus_val_print): Two args are ignored; remove them. Change caller.
4140 (val_print): Use unpack_long rather than pointer-deref.
4143 (unpack_long, unpack_double): Use bcopy rather than pointer-deref
4144 to avoid alignment problems.
4145 (value_being_returned): Error if return value unknown.
4146 (set_return_value): Add bogosity warning, FIXME. *
4148 * TODO: A woman's work is never done.
4150 * Makefile.dist: Distribute REMOTE_OBS into tconfig files.
4151 Separate INCLUDE_CFLAGS for use with lint. Add LINTFILES.
4152 Add ieee-float.o to OBS.
4153 * tconfig/{nindy960,vxworks68,vxworks960}: Include the desired
4154 REMOTE_OBS remote-interface files in the TDEPFILES and TM_FILE.
4155 * tconfig/i960: FIXME. Half-merge, produce warning if config'd.
4157 Changes to generalize the VxWorks RPC protocol slightly, to handle
4158 i960 as well as 68000.
4160 * vx-share/dbgRpcLib.h (VX_SOURCE_STEP): Add.
4161 * vx-share/reg.h: Produce i960 regs #ifdef I80960
4162 * vx-share/xdr_ptrace.c: Skip FPA registers if 960.
4163 * vx-share/xdr_rdb.h: Add SOURCE_STEP struct and xdr decl.
4164 * vx-share/xdr_rdb.c: Add xdr_SOURCE_STEP routine.
4165 * vx-share/xdr_regs.c: Add xdr_regs, xdr_fp_status, xdr_ext_fp
4166 for i960. Change xdr_vectors to xdr_opaques for 68k registers,
4167 so they will move in target byte order rather than network
4168 byte order (happens to be the same).
4170 Mon Feb 25 03:41:44 1991 John Gilmore (gnu at cygint.cygnus.com)
4172 * tm-convex.h (END_OF_TEXT_DEFAULT): Remove #if 0'd block.
4174 Sun Feb 24 00:55:53 1991 John Gilmore (gnu at cygint.cygnus.com)
4177 Add contribution lines to various files, showing where they
4180 * breakpoint.c (break_insn, check_break_insn_size,
4181 read_memory_nobpt): Remove to mem-break.c.
4183 * xm-*.h, param-no-tm.h, tm-29k.h, valprint.c: Change BYTE_ORDER to
4186 * tm-29k.h (STAB_REG_TO_REGNUM): Warn user if symbol table
4187 entry has bad register number. This change is not
4188 tested in this release, FIXME.
4190 * frame.h: Eliminate Frame_unknown in favor of a simple zero.
4193 * value.h: Force value's contents field to be aligned to hold
4194 at least a double or a long long (if supported). This avoids
4195 doing bcopy's in and out of the contents field.
4197 (step_1): Avoid coredump under obscure circumstances when we
4200 * symtab.h (misc_info): Add field to misc function vector for
4201 any kind of cached information the target code desires. AMD
4202 29000 uses this to avoid repeating examine_function_prologue's.
4204 * coffread.c: Lint. Remove static symfile, read_section_header.
4205 core.c (have_core_file_p): Lint: remove.
4206 expprint.c (print_subexp): Lint.
4207 infptrace.c, valops.c, valprint.c: lint.
4209 Roll in changes from vxgdb-5.0.1:
4211 * symtab.h: Comment byte order of each address class. Add
4212 LOC_LOCAL_ARG for frame-relative args (960).
4213 expread.y: Use LOC_LOCAL_ARG where LOC_ARG is used.
4214 symtab.c, symmisc.c: ditto.
4216 * infrun.c (init_wait_for_inferior): Clear stop_signal.
4218 * remote.c (remote_resume): Error if resume with a signal.
4220 * symfile.c (prim_record_misc_function): Clear misc_info.
4221 (fill_in_vptr_fieldno): Check stub type of arg.
4223 * valops.c (value_cast): Avoid looking up names of types whose
4224 name we don't know, to prevent coredump. Sun CC produces typedef
4225 rtx and the name of *rtx is zero...
4227 Mon Feb 18 21:16:25 1991 John Gilmore (gnu at cygint.cygnus.com)
4229 Roll in changes from final AMD 29000 port (Tiemann).
4231 tconfig/am29k: Add COFF_ENCAPSULATE and TARGET=TARGET_AM29K
4232 for ../include/a.out.encap.h. This might not work now that BFD
4233 is separately compiled. Instead, BFD support for encap will have
4234 to translate machine type 29k into the right COFF_MAGIC.
4236 * infcmd.c: Remove references to inferior_pid that aren't used
4237 in actual ptrace calls; use target_has_execution, etc.
4238 (have_inferior_p): Remove function.
4239 (program_info): Print target info rather than "process number";
4240 avoid gratuitous messages unless from_tty.
4241 (run_stack_dummy, finish_command): Set proceed_to_finish.
4242 infrun.c: Remove inferior_pid refs. Decl & init proceed_to_finish.
4243 main.c: Lint. Lose have_inferior_p().
4244 inferior.h (have_inferior_p): Remove, lint.
4245 (proceed_to_finish): Add flag to ask that all regs be saved
4246 by normal_stop, for the few commands that need it, speeding up
4247 serial I/O. Add comments to stop_registers.
4249 * remote-eb.c: Remove newline from breakpoint message we grep
4250 for. Never time out when running the user program.
4254 Wed Feb 13 15:34:40 1991 John Gilmore (gnu at cygint.cygnus.com)
4256 Roll in changes from vxgdb-5.0.1:
4258 * dbxread.c (read_dbx_symtab): If we encounter a "FORTRAN COMMON"
4259 symbol in its raw form, we are processing an unlinked ".o" file.
4260 See if the target environment has assigned it an address, using
4261 target_lookup_symbol (VxWorks does), and enter it into the symtab
4264 * tm-vxworks.h (FRAME_CHAIN, FRAME_CHAIN_VALID): Override usual
4265 68k versions for a simpler version that assumes zero FP at bottom.
4266 Fixes bug of truncated stack reports.
4268 * target.h (target_lookup_symbol): Define this routine's args
4269 and result, finally.
4271 * target.c (nosymbol): Default routine for target_lookup_symbol.
4272 (target_default): Default lookup_symbol and call_function too.
4273 (files_info): Only print has_all_memory warning if a non-dummy
4276 * remote-vx.c (vx_read_register, vx_convert_to_virtual,
4277 vx_convert_from_virtual): If target does not have floating point,
4278 zero register "values", and avoid doing cross-net conversions.
4279 (vx_lookup_symbol): Rename net_lookup_symbol, add to vectors.
4280 (vx_open): Rearrange code that attaches to target and reads
4281 symbols for all loaded modules, to work if some of the modules
4282 are not accessible. Add symbol_stub() and add_symbol_stub()
4283 as callbacks from catch_errors(). Allow connect attempt to be
4284 interrupted painlessly with ^C (FIXME, there are still some bugs
4285 if the interrupt happens during symbol reading.). Print
4286 final message with puts_filtered, since symbol messages are
4291 * main.c (catch_errors): Only print errstring if non-null.
4292 (command_loop): Avoid an ioctl per command to test ISATTY.
4294 * remote-vx.c (net_load): make static; avoid sophomoric msg.
4295 (vx_xfer_memory): Return correct result!
4296 (vx_files_info): Indicate whether target has float or not.
4297 (vx_lookup_symbol): Complain, not error, if target gone.
4298 (vx_open): Print "Connected" msg before disabling immediate-quit.
4299 [FIXME: lookup_symbol and vx_open changes need testing.]
4301 target.c, remote-eb.c, inftarg.c, am29k-opcode.h, target.h,
4302 tm-29k.h, tmm-vxworks68.h, symfile.c, gdb-int.texinfo: Add
4303 contributor lines and update copyrights to 1991.
4305 Changes from an attempted H-PUX host port:
4307 * infptrace.c (PT_ATTACH, PT_DETACH): Handle HP/UX, which
4308 defines PT_ATTACH and PT_DETACH but not PT_KILL.
4309 * remote-eb.c (eb_open): Misplaced endif kills sysv H/PUX.
4310 * remote-vx.c: include <sys/time.h> for HPUX.
4311 * hp300hpux-xdep.c (fetch_core_registers): Rewrite old
4312 "core_file_command" routine to BFD regime. May not work yet.
4314 Attempted port of "gdb-3.4 Van Jacobson xgdb" to modern gdb.
4316 * xgdb.c: Replace X10 version with some VJ version.
4317 (FIXME: Its copyright assignment is not on record.)
4318 * xgdb.c: Update include files to X11R4 (Xaw crud).
4319 (xgdb_display_source, create_text_widget): fix call to
4320 get_filename_and_charpos. Rewack source window stuff for X11R4
4321 (gleaned from include files, and "nm's" of binary libraries, since
4322 I had no doc available).
4323 (append_selection, append_selection_word): Disable with FIXME
4324 since R4 changed interface here.
4325 (create_buttons): Add back the old set of buttons.
4326 (xgdb_create_window): Fix call to XtInitialize (&argc not argc).
4328 * Makefile.dist (xgdb, xgdb-init.c): Update for X11R4 on Suns.
4329 Roll VERSION to 3.94 (not yet final though).
4331 Sat Feb 9 09:46:25 1991 John Gilmore (gnu at cygint.cygnus.com)
4333 * obstack.h (obstack_ptr_grow, obstack_ptr_grow_fast,
4334 obstack_int_grow, obstack_int_grow_fast): Eliminate
4335 cast on left of assignment, which gives MIPS cc fits and is
4338 * sparc-pinsn.c (print_insn): Eliminate 'set' test, subsumed by
4339 F_ALIAS. Use printf, not fprintf, when not passing a file
4341 (compare_opcodes): Check that identical instructions have
4342 identical opcodes, complain otherwise.
4344 * sparc-opcode.h (st %fsr): Fix opcode "lose" mask. This
4345 was reported by Roland McGrath.
4346 (unimp): Only match if exactly zero instruction. (Roland)
4347 (branches and traps): Generate all variations of these
4348 instructions with macros, based on a single call that defines
4349 each condition name and its binary representation.
4350 (set): Turn on alias bit, to avoid test in sparc-pinsn.c.
4352 * valprint.c (val_print_fields): Take, and use, format parameter.
4353 This means that "p/x struct" again prints the elements in the
4354 desired format. Changed callers.
4356 * stack.c (frame_info): Use filtered output, and indicate wrap
4357 points. Remove kludgy formatting designed to avoid line wrap.
4359 * utils.c (wrap_here): If the line is already full (because
4360 we had printed a long indent or long wrapped string), do an
4361 immediate newline-and-indent.
4363 * m68k-pinsn.c (print_insn_arg): Bugfix from
4364 ntmtv!thompson@ames.arc.nasa.gov (Mike Thompson): 'bkpt #0'
4365 instruction is incorrectly disassembled as bkpt #8.
4367 * dbxread.c (end_psymtab): Bugfix from Peter Schauer
4368 <pesrem@regent.e-technik.tu-muenchen.de>: If you want to set a
4369 breakpoint in a *.y file gdb will say Reading in symbols for *.y...
4370 and then will dump core (sometimes). I traced it back to an
4371 uninitialized symfile_name in psymtab_to_symtab.
4372 (const_vol_complaint): Add quotes to message.
4373 (define_symbol): Only believe line number if gcc_compiled.
4374 Avoid allocating symbol if we will not return it.
4376 Add target strata support so that newly established targets go
4377 into their right place in the target stack (e.g. a new exec file
4378 doesn't wipe out the ability to access the running process).
4380 * target.h, core.c, exec.c, inftarg.c, remote-eb.c,
4381 remote-nindy.c, remote-vx.c, remote.c, target.c: Add to_stratum
4382 and initialize it properly in all the targets.
4384 * target.h: Document strata. Change return type of push_target.
4386 * target.c (nomemory): new function for dummy memory access.
4387 (tcomplain): Rename complain, now also used in symfile.c.
4388 (push_target): Push targets within strata. New return value shows
4389 whether new target is on top of stack or not. Always keep dummy
4391 (target_files_info): Ignore dummy target.
4393 * core.c (core_open): Warn user, and skip accessing file, if the
4394 core target is not the topmost target in the stack.
4395 * remote-nindy.c (nindy_create_inferior): Avoid unpush_target, now
4398 * remote-vx.c: Remove vx_prepare_to_store from vxworks memory
4399 target_ops, it doesn't belong there since we have no regs there.
4400 Change name of target from machine => memory to clarify.
4402 Thu Feb 7 16:32:09 1991 John Gilmore (gnu at spiff.cygnus.com)
4404 * Freeze version 3.93 for release.
4406 * Makefile.dist: Handle vx-share and nindy-share subdirs
4407 properly when building gdb.tar.Z.
4409 * symtab.c: lint; add no_symtab_msg to consolidate the messages
4410 printed in various places, so I could change just one copy.
4412 * dbxread.c, coffread.c: Change references to bfd->iostream
4413 to cast to FILE *, now that BFD avoids needing types defined
4414 in other header files.
4416 Tue Feb 5 21:39:35 1991 John Gilmore (gnu at cygint.cygnus.com)
4418 * command.c, dbxread.c, expprint.c, infcmd.c, infptrace.c,
4419 infrun.c, printcmd.c, remote-nindy.c, source.c, sparc-tdep.c,
4420 sparc-xdep.c, symfile.h, symmisc.c, utils.c, valprint.c: Lint
4421 (actually gcc -Wall).
4423 * dbxread.c: Remove first_global_sym, last_global_sym, since
4424 they are never referenced.
4426 * defs.h (baud_rate): Declare.
4427 main.c: Define it, and add the -b option to set it.
4429 * gdb-int.texinfo: Add text on how to define a new host or target
4430 architecture, prompted by Per Bothner's questions about MIPS
4433 * gdb.texinfo: Document "complaints". Change doc of -q since
4434 gdb no longer prints the copyright and blurb if you specify a file
4435 name to be debugged (just like Emacs). Add doc for Nindy-specific
4436 command line flags for specifying target serial port and such.
4437 Update copyright to 1991.
4439 * gdbcore.h: Remove a large mass of now-useless crud, since BFD
4440 has taken over for us the job of ripping up executable files. The
4441 crud caused Per Bothner's port to not compile.
4443 * infrun.c (normal_stop): Avoid printing "Program exited
4444 normally" if we are in batch mode. This allows a GDB which
4445 executes a program on a target system, to behave like a Unix
4446 command (input from stdin, output to stdout, no extraneous
4449 * main.c (main): Allow additional machine-dependent command line
4450 options to be specified with the ADDITIONAL_OPTIONS,
4451 ADDITIONAL_OPTION_CASES, ADDITIONAL_OPTION_HELP, and
4452 ADDITIONAL_OPTION_HANDLER macros. Also allow machine-dependent
4453 processing to occur just before the main loop with
4454 BEFORE_MAIN_LOOP_HOOK.
4455 (main): If a "core file" argument is specified, and it is not a
4456 core file, try it as a process ID to attach.
4457 (symbol_completion_function): Attempt to cope with
4458 "show screen-" TAB, not very successfully. This needs more work,
4460 (batch_file): New function, returns whether we are reading
4461 commands from an interactive tty on stdin, or from somewhere else.
4462 Called by normal_stop since it doesn't get from_tty passed down
4463 to it like many commands do.
4465 * remote-nindy.c: Handle command line options for nindy
4467 (nindy_before_main_loop): Prompt user for tty name if they
4468 don't specify it before getting to the interactive command loop.
4470 * tm-i960.c: Add ADDITIONAL_OPTIONS, etc, to handle -O, -brk,
4471 and -r command line options. Also add hook before main loop
4472 to make it easy to specify a tty.
4474 * TODO: More things to do, one done.
4476 Mon Feb 4 23:57:39 1991 John Gilmore and Mike Tiemann (at cygint.cygnus.com)
4478 * dbxread.c: Make complaint() calls pass pointer, not struct.
4479 Add complaints about badly formatted C++ type information
4480 (const/volatile indicator, and parse errors resulting in
4481 error_type). Fix C++ virtual member fn comment.
4482 (read_struct_type): Avoid bumping pointer if we got a parse
4483 error; this prevents our walking beyond the end of a string.
4484 Terminate loop on null char as well as semicolon.
4485 (process_one_symbol): Fix the LBRAC fix so that it uses the
4486 last previous SLINE, FUN, or SO record's PC address. C++ debug
4487 symbols did not have SLINE records in a useful order compared
4488 to the LBRAC records.
4489 (define_symbol): Handle "catch" records.
4491 * symtab.c (check_stub_type): Added new complain
4492 `stub_noname_complain' and added a consistency check to
4493 keep the debugger from crashing when finishing from an
4494 exception frame. A real fix will be needed later.
4496 Sat Feb 2 10:43:05 1991 John Gilmore (gnu at cygint.cygnus.com)
4498 * infcmd.c (attach_command): Make global.
4500 * Makefile.dist (REMOTE_OBS): Make these compile by default,
4501 but make them easy to comment out. Perhaps later they should
4502 be enabled by what CPU you configure for? FIXME.
4503 (VERSION): Roll to 3.93.
4504 (pinsn.o): Remove rule for obsolete file.
4505 (dbxread.o,coffread.o,mipsread.o): Use ${srcdir} explicitly.
4507 Run down a problem that manifested by printing the wrong function
4508 name in stack traces of read_ofile_symtab. Turned out that the
4509 problem was the SunOS 4.1.1 (and previous) C compiler outputs
4510 the LBRAC symbol with an address in the *data* segment, which
4511 blew our binary search through the blocks.
4513 * dbxread.c: Use the complain() facility consistently to bitch
4514 about problems in the symbol file we are reading.
4515 (finish_block): Add code to check the nesting of the blocks;
4516 complain and Procrust them to fit if wrong.
4517 (make_blockvector): Check the order of the blocks, complain
4518 [but don't cope] if wrong.
4519 (process_one_symbol): ifndef SUN_FIXED_LBRAC_BUG, check LBRAC
4520 symbols to be sure their PC value is greater than the last SLINE
4521 (line number) symbol we've seen, complaining and adopting the
4522 SLINE PC value if wrong.
4524 * symfile.h (struct complaint, complaint_root, complain,
4525 clear_complaints): Add.
4526 * symfile.c (complain, complaint_root, clear_complaints): Add
4527 facility to deal with non-fatal complaints and to regularize their
4529 (symbol_file_add): Clear complaint counters to allow new complaints.
4530 (initialize_symfile): Add 'set complaints' and 'show complaints'.
4532 * dbxread.c (dbx_symfile_read): Remember the address and size
4533 of the string table for the main symbol file, so we won't read it
4535 (dbx_psymtab_to_symtab): Fix the check for main symbol file,
4536 to avoid reading the string table yet again. Lint.
4537 (throughout): Improve filtered output, including word wrap.
4538 (read_range_type): Improve Bothner's fix to handle other types too.
4540 * utils.c: Improve line wrap implementation. Handle unlimited
4541 width by making chars_per_line unsigned.
4542 (puts_filtered): New, easy, function.
4544 * defs.h (puts_filtered): add.
4546 * mipsread.c (compare_symbols, sort_symtab): Remove these fns,
4547 call the identical sort_symtab_syms() in symfile.c instead.
4549 * expread.y: Suggest the `file' command rather than `symbol-file'.
4551 * command.h (enum var_types): Add zinteger for seroable
4553 * command.c (do_setshow_command): Handle var_zinteger. Restructure
4554 nested if's into a switch.
4556 * breakpoint.c (bpstat_print): If bpstat "print" flag is not set,
4557 we did not stop because of a breakpoint (it must have been for
4558 some other reason, like a "stepi"), so don't print anything.
4560 * symtab.c: Include <sys/types.h> all the time. Now that BFD
4561 doesn't include <sys/types.h>, old SunOS's require it for
4564 Sat Feb 2 10:39:15 1991 Per Bothner (bothner@cs.wisc.edu)
4566 A test port of gdb-3.92.6 to the Sony NEWS.
4569 Don't normally link in remote- or vx stuff.
4570 Some of it doesn't compile, and it wastes space for 99% of the users.
4571 Remove reference to no-longer-used HAVE_VPRINTF.
4572 Fixed BFD_DEP typo to BFD_DIR.
4574 Fix cast in arg to bfd_h_getlong.
4575 Make char *prefix be const.
4576 Fix how certain range types are mapped into builtin unsigned int types.
4578 Remove 2 #includes. They cause errors (on Sony, at least),
4579 and aren't needed (they wern't in earlier versions).
4581 print_address_symbolic should never demangle labels
4582 (since it prints *assembler-level* labels).
4584 [This was superseded by the change to printcmd below.]
4587 Add some "volatile" return types to avoid warnings.
4588 If MISSING_VPRINTF add vprintf function and not just macro
4589 (since vprintf is used in printcmd.c).
4591 Unless __GNUC__, use obstack_grow instead of obstack_ptr_grow.
4592 (The latter isn't grokked by some PCC-based compilers.)
4594 [This change is in abeyance, we prefer to fix obstack_ptr_grow.]
4596 Make chunk size of dont_print_obstack 32*4 instead of default 4096.
4597 * nindy-share/coffstrip.c
4598 Added some forward declarations (otherwise, gcc complains
4599 about implicit extern redefined as static).
4601 Sun Jan 20 02:38:19 1991 John Gilmore (gnu at cygint.cygnus.com)
4603 Changes inspired by Per Bothner:
4604 * printcmd.c (print_address_symbolic): Take additional parameter
4605 specifying whether to demangle.
4606 (print_address): Pass in asm_demangle to control demangling.
4607 (print_address_demangle): New fn, takes explicit arg to control
4609 * utils.c: Add new vars demangle and asm_demangle, and let them
4611 (fputs_demangled): If !demangle, just print the argument.
4612 (fprint_symbol): If !demangle, just print raw symbol.
4613 * valprint.c (val_print): Call print_address_demangle rather than
4614 print_address, to cause demangling to depend on the global
4615 rather than assembler-level demangling setting.
4616 * WHATS.NEW, gdb.texinfo: Document.
4618 * main.c (show_command): Show all settings if no arg.
4619 (initialize_main): Make "info set" the same as naked "show".
4620 * command.c (cmd_show_list): Handle prefix commands in the
4621 list, and print the name of the setting as well as its English
4622 description and value.
4624 Allow gdb functions to specify where a line should wrap if it
4625 exceeds the size of a terminal line. Use it to make the output
4627 * utils.c (set_screen_width_command): New fn, mallocs a buffer
4628 of the right size when screen width changes.
4629 (set_screensize_command, screensize_info): Remove #if 0'd fns.
4630 (wrap_here): New fn, indicates a point in the output where we
4631 should wrap the line rather than just letting it overflow at a
4633 (fputs_filtered): Implement wrapping.
4634 (n_spaces): New fn, returns a pointer to N spaces.
4635 (print_spaces_filtered): Use n_spaces.
4636 * defs.h (n_spaces): Declare.
4637 * stack.c (print_frame_info): Wrap with 4-space indent after
4638 fn name and before filename and line number.
4639 * printcmd.c (print_frame_args): Wrap with 4-space indent
4640 before each argument name is printed.
4641 * valprint.c (value_print): Wrap with no indentation before
4643 (val_print_fields): Wrap with indentation relative to nesting
4644 level before each field name.
4645 (val_print): Wrap with nesting indentation before array elements.
4646 * command.c (do_setshow_command): Avoid extra newlines,
4647 wrap with 4-space indent around values printed, end with period.
4648 * WHATS.NEW, gdb.texinfo, gdb-int.texinfo: Document.
4650 * breakpoint.c (breakpoint_1): Implement addressprint for
4651 "info breakpoints" display. Change file name and line number
4652 format to " at file:nnn" rather than " (file line nnn)".
4653 * gdb.texinfo: Document.
4656 Fri Jan 18 07:21:25 1991 John Gilmore (gnu at cygint.cygnus.com)
4658 Frozen for gdb-3.92.6 release.
4660 README, WHATS.NEW: Update for 3.92.6 release.
4662 tconfig/{altos, i386v, i386v32, m88k, umax}: Eliminate
4663 coffread.o from configs since it is now built by default.
4664 tconfig/{3b1, altosgas, arm, convex, hp300bsd, hp300hpux,
4665 i386v-g, i386v32-g, isi, merlin, news, news1000, np1, pn,
4666 pyramid, symmetry, vax, vxworks68}: Eliminate dbxread.o
4667 from configs since it is now built by default.
4669 Makefile.dist: Update for release 3.92.6. Handle files that
4670 have been moved to ../include, ../getopt, or ../bfd. Add
4671 saber.suppress and tests directory. Add config.status to
4672 the release (it will say "none").
4674 coredep.c: Minor formatting fixes.
4676 These changes were made in early December but only checked in now:
4677 * nindy-share/Onindy.c, nindy-share/coffstrip.c,
4678 nindy-share/nindy.c: lint
4679 * nindy-share/nindy.c (ninStopWhy): Don't byteswap the
4680 register values coming back from the target; we store values
4681 in target byte order everywhere.
4683 Wed Jan 16 19:01:37 1991 John Gilmore (gnu at cygint.cygnus.com)
4685 * am29k-opcode.h, am29k-pinsn.c: Add 29050 opcodes.
4687 * valprint.c (cplus_val_print, val_print_fields): New functions,
4688 which print C++ objects. They conspire to avoid printing a
4689 virtual base class more than once, following all the twists and
4690 turns of C++ virtual base rules.
4691 (val_print): Call the above rather than do it by hand.
4693 * symfile.c (symbol_file_add): Only reset symfile_mtime for main
4694 symbol file, not for added files like shared libs. This really
4695 needs to be generalized to a timestamp per file.
4697 * core.c (cleanup_core): Avoid coredump if no core file.
4699 * config.gdb: Accept -host or -target in place of +host or
4702 * coffread.c (find_linenos): Avoid desupported BFD interface
4703 to line numbers. We still read them manually rather than using
4704 BFD's "generic" features.
4706 * gdbrc.tex, threecol.tex: Add GDB reference card and its
4708 Makefile.dist: Add refcard to OTHERS list for creating tar files.
4710 * Makefile.dist: Eliminate use of $< in explicit targets.
4712 * readline/Makefile: Use $< rather than $*.c, which does not
4713 include the VPATH in GNU Make.
4715 * tconfig/i960-bout, tconfig/i960-coff: These are identical
4716 copies of tconfig/i960, added for global configuration
4717 compatability. All i960 versions can read both coff and b.out.
4719 * tm-88k.h: Fix multiline macro that lacked \'s. Remove
4720 COFF_FORMAT and COFF_CHECK_X_ZEROES since these are now handled
4723 * TODO: Think of more things to do.
4725 Wed Jan 2 19:09:29 1991 John Gilmore (gnu at spiff.cygnus.com)
4727 tconfig/{am29k,i960,sun2*,sun3*,sun4*}: Eliminate config
4728 of sdb versus dbx debug symbols. Add kludge for 68881 80-bit to
4729 64-bit float conversion.
4731 tconfig/sun4, tconfig/sun3, xconfig/sun4, xconfig/sun3: Make
4732 equivalent to sun?os4 so global config works.
4734 Wed Jan 2 18:20:51 1991 John Gilmore (gnu at spiff.cygnus.com)
4736 Fix from Eberhard Mattes <mattes@azu.informatik.uni-stuttgart.de>
4738 * main.c: Only declare linesize once; declare pagesize not at
4739 all, since it is never used.
4740 (main): Clear newly allocated line before it is used.
4742 Fri Dec 28 00:13:42 1990 John Gilmore (gnu at cygint)
4744 Further stabilization for the Intel 960.
4746 * Makefile.dist: Parameterize the location of the "include"
4747 and "bfd" directories, as well as "getopt". Add symfile.c.
4748 Link in both dbxread and coffread. Fix up "make depend" to
4749 rewack the locations of include, bfd, and getopt in its output.
4751 * README: Document moving include files, improve some of
4754 * coffread.c: Move common code out to symfile.c. Change
4755 symbol_file_command style interface to use new *_symfile_init
4756 and *_symfile_read interface under BFD. Use BFD internal
4757 info to locate line table, symbols, etc.
4759 * core.c (core_fetch_registers): Rename to get_core_registers
4760 to avoid confusion with fetch_core_registers.
4761 (register_addr): Move to coredep.c, which is already machine
4762 dependent. This leaves core.c pretty clean of dependencies.
4764 * coredep.c (register_addr): Accept this routine from core.c.
4766 * dbxread.c: Move common code (with coffread.c, etc) into new
4767 symfile.c. Each psymtab now contains a pointer to the
4768 format-dependent function that knows how to read it in. Make
4770 (dbx_psymtab_to_symtab): Renamed from psymtab_to_symtab_2.
4771 (process_one_symbol): Add code to complain about a "compiler bug
4772 we muzzle here", if we actually see it.
4774 * eval.c (evaluate_subexp): Insert missing "break" statements
4775 in code that determines whether a variable is an lvalue in
4776 memory, register, or whatever. I detected this via a compiler
4777 bug in which it *almost* mashed out the whole switch statement.
4779 * gdb-int.texinfo: Add minor sections on configuring gdb for
4780 release, and about the README file.
4782 * infcmd.c (registers_info): Fix formatting somewhat. Still
4783 not as pretty as before, but it handles byte swapping.
4785 * remote-nindy.c: If data cache routines are interrupted while
4786 waiting for the remote end, be sure that any uninitialized cache
4787 blocks are on the free list, not on the valid list!
4789 * symfile.h: Flesh out this header file with all the various
4790 routines and variables that have been merged in from dbxread.c
4791 coffread.c, and symtab.c to symfile.c.
4793 * symfile.c: New file, containing code common to dbxread.c,
4794 coffread.c, and some code from symtab.c. All generic code for
4795 reading symbol files should be in here now.
4796 (unrecord_misc_function): Remove unused function.
4798 * symtab.h: Remove file-reading things to symfile.h.
4800 * symtab.c: Remove file-reading things to symfile.c.
4802 * tm-i960.h: Fix FRAME_CHAIN types; define PRINT_RANDOM_SIGNAL
4803 to decode i960 fault types.
4805 * target.h, remote.c, remote-eb.c, remote-vx.c, remote-nindy.c,
4806 target.c: Change type of the "resume" function from int to void,
4807 since its result was never used.
4809 Sat Dec 22 02:51:40 1990 John Gilmore (gnu at cygint)
4811 * main.c: Replace "stupid" with "caution"; you now "set caution
4814 * printcmd.c (print_scalar_formatted): Fix typo in 'g' format
4816 * infcmd.c (do_registers_info): Call val_print to deal with the
4817 byte order of the registers being printed. FIXME, this makes
4818 the formatting of the output uglier.
4820 * infcmd.c (wait_for_inferior): If PRINT_RANDOM_SIGNAL is
4821 defined, call it for signals the debugger doesn't itself use.
4822 The i960 uses this for more detailed fault information.
4824 * remote.c (remote_open): If arg is null, print help rather than
4827 * sparc-xdep.c (register_valid): Avoid declaring size, since
4828 various modules will think of various sizes depending on the
4829 architecture of their tm-file. FIXME, we need protection against
4830 actually entering one of those modules, which would clobber
4831 storage if not for the target architecture compiled into gdb.
4833 * stack.c (up_command, down_command): Always print the frame
4835 (up_silently_command, down_silently_command): New commands
4838 * i960-pinsn.c (reg), i960-tdep.c: Lint.
4840 * i960-tdep.c (i960_frame_chain_valid): Lookup_symbol now takes
4841 more parameters than it used to.
4843 * findvar.c (registers): Increase slop to 256 bytes, which should
4844 protect us against even most RISC machines with large register
4846 (locate_var_value): Move declaration inside related ifdef.
4848 * remote-nindy.c (): Use TIOCSETN rather than TIOCSETP
4849 throughout, to avoid throwing away buffered input from the board.
4850 (nindy_wait): Supply_register takes addr_of_value, not value.
4851 (i960_print_fault): Renamed from i80960_fault.
4852 (nindy_fetch_registers): Avoid have_regs stuff, just get them.
4853 (nindy_store_registers): Avoid regs_changed stuff, just stuff
4855 (nindy_create_inferior): Don't bother to write PC_REGNUM since
4856 we can set the PC in the call to proceed(). Unpush nindy_ops
4857 before pushing it on top, to avoid message to user. Eliminate
4858 commentary from Unix machines that just misleads here.
4859 (reset_command): Fix error message to suggest target command.
4861 Wed Dec 19 11:03:56 1990 John Gilmore (gnu at cygint)
4863 Release 3.92.5 as frozen.
4865 Stabilize the merged release...with help from lint, Saber C,
4868 Everywhere: Add include files needed to declare return types
4869 of functions called.
4871 * gdb.texinfo: Roland Pesch is documenting gdb, glory be!
4873 * breakpoint.h: Add undeclared breakpoint functions, and some
4874 functions for display handling since I couldn't think of a better
4877 * breakpoint.c (insert_breakpoints): Make code for disabling
4878 shared library bkpts more likely to work. It's used when we
4879 rerun a program and stop before the shared library has been
4881 (breakpoint_cond_eval, bpstat_stop_status): Pass arg as int,
4882 cast from pointer, so it squeezes through catch_errors.
4883 (bpstat_stop_status): Fix logic broken some time ago. We now
4884 always create a bpstat if the stop address matches a breakpoint,
4885 even if we don't stop there -- just like the old code used to do
4886 before I got my fingers into it (sigh).
4887 (breakpoint_1): Print "ignore count" after "stop only if"
4888 condition, since that's how it actually works.
4889 (mention): Handle watchpoints as well as breakpoints.
4890 (watch_command): use set_raw_breakpoint and mention to do most
4891 of the work (and initialize all the fields!). Only pass one
4892 arg to parse_c_expression, since that's all it takes.
4894 * command.c (not_just_help_class_command): Rename arg to args
4895 since we ignore "unused argument" warnings on vars named "args".
4896 inflow.c (child_terminal_info): ditto.
4897 infptrace.c (kill_inferior): ditto
4898 main.c (catch_errors, version_info, quit_command, pwd_command,
4899 source_command, dump_me_command, editing_info,
4900 set_history_size_command, set_history, show_history,
4902 stack.c (locals_info): ditto
4903 target.c (target_files_info): ditto
4904 valprint.c (set_input_radix, set_output_radix): ditto
4906 * core.c: Remove old variables for handling core and exec file
4907 sections (data_start, data_end, stack_start, stack_end,
4908 reg_stack_start, reg_stack_end, reg_stack_offset, text_start,
4909 text_end, exec_data_start, exec_data_end, text_offset,
4910 exec_data_offset, data_offset, stack_offset). They're
4911 superseded the more general build_section_table and
4913 (get_exec_file): Mention the `file' command.
4914 (read_memory_check): Rename to memory_error, and only call it
4915 in the case of an actual error.
4916 (read_memory, write_memory): call memory_error.
4917 (core_fetch_registers): Register section name is ".reg".
4919 coredep.c: Remove a bunch of crud now that all this file does
4920 is pull the registers out of a core file.
4921 (fetch_core_registers): Rewrite to actually work, I hope.
4923 dbxread.c: Use a.out.gnu.h, not system a.out, now.
4924 Replace index() with strchr(). Remove all the pre-BFD macro
4925 definitions for accessing the symbol file.
4926 (struct dbx_symfile_info): Encapsulate the information that
4927 dbx_symfile_init needs to pass to dbx_symfile_read in this
4930 (dbx_new_init, dbx_symfile_init, dbx_symfile_read,
4931 dbx_symfile_discard): Rearrange symbol file reading to divide
4932 the format-specific part from the format-independent part,
4933 leaving the format-independent part such as file name expansion
4934 and opening in symtab.c. This replaces
4935 partial_symbol_file_open and partial_symbol_file_read.
4936 Symbol_file_read, add_file, add_file_target_command,
4937 add_file_addr_command move to symtab.c. Pass an explicit
4938 "mainline" flag for when reading the main symbol table, rather
4939 than relying on the offset address to be zero or nonzero.
4941 (dbx_symfile_read): Don't allow void *'s to be printed as
4943 (SWAP_SYMBOL): Use bfd routines to byte-swap the symbols.
4944 (ADD_PSYMBOL_TO_LIST): Make the "function call rather than
4945 macro" debug version really work.
4946 (read_dbx_symtab): Remove unref'd parameter inclink.
4947 Avoid swapping N_SLINE symbols, for speed.
4948 Merge N_TEXT!N_EXT case with the other external symbol
4949 definitions' case. Add comments.
4950 (start_psymtab): Allocate the symfile name in the psymtab on
4951 the psymbol_obstack, rather than using the caller's storage.
4952 (end_psymtab): Only allocate a dependencies list if there are
4954 (psymtab_to_symtab_2): Use BFD when reopening file to read
4955 its symbols for real.
4956 (read_struct_type): Add FIXME comments where it needs work
4958 (read_huge_number): Add FIXME about overflows.
4959 (read_range_type): Add FIXME about comparing a long to 1<<32.
4961 * coffread.c: Minor changes to move things closer to the new
4962 regime with symtab.c and dbxread.c Major work is still needed
4965 * exec.c (exec_file_command): Remove old variables (see core.c
4967 (xfer_memory): If memory transfer is right at the end of a
4968 section, don't lose.
4970 * findvar.c (get_saved_register): If value is in a real
4971 register, LVAL is lval_register, not lval_memory.
4973 frame.h: Declare print_sel_frame and record_selected_frame.
4975 gdb-int.texinfo: New file, for GDB internals documentation.
4976 Very simple, unformatted doc of cleanups is there for now.
4978 gdbcore.h: Remove obsolete variables that described a.out
4979 section addresses and offsets. (See core.c above.)
4980 Declare fetch_core_registers and registers_fetched.
4982 getopt.c: Declare char *alloca(); even on SPARC.
4984 infcmd.c (run_command): Call target_kill rather than
4986 (step_command, next_command, stepi_command, nexti_command):
4987 Declare from_tty parameter even though we don't use it.
4988 (run_stack_dummy): argument BUFFER is a char array, not
4989 a pointer to REGISTER_TYPE.
4990 (finish_command): using_struct_return needed a value *,
4991 not a struct symbol *.
4993 * infptrace.c (child_xfer_memory): To avoid dependency on
4994 where sections are in memory, try PT_WRITE_D and if that fails,
4995 try PT_WRITE_I. Most Unixes don't care which you use.
4997 * infrun.c (step_resume_break_shadow): Change to array to
4998 match other breakpoint shadow storage.
4999 (clear_proceed_status): Pass address of bpstat to
5000 bpstat_clear, not the bpstat itself.
5001 (child_create_inferior): FIXME comment about if the child
5003 (start_inferior): Remove old function.
5004 (child_open): Use target_kill rather than kill_inferior.
5005 (wait_for_inferior): Ditto.
5006 (insert_step_breakpoint, remote_step_breakpoint): Use
5007 new step_resume_break_shadow.
5009 * inftarg.c (child_wait): If all child processes die,
5010 pretend that the one being waited for exited with signal 42.
5012 * main.c (command_line_input): When scanning for comments,
5013 don't coredump on unclosed quotes.
5014 (quit_command): Use target_kill rther than kill_inferior.
5015 (_initialize_main): Rename class_user from "user" to
5018 * printcmd.c (print_command_1): Initialize "fmt" if no format
5019 is specified by the user.
5020 (print_frame_args): Only add to args_printed if we are
5021 actually fetching args from the stack (avoiding undefined
5023 (_initialize_printcmd): Remove bogus \{ from string.
5025 * remote-eb.c (eb_open): Avoid coredump on no argument.
5027 * remote-nindy.c: Bring out of Intel environment into new
5028 target environment. Remove all conditional compilation on
5029 I80960. Massive hacking throughout.
5030 (nindy_xfer_inferior_memory): New routine stolen from
5032 (nindy_create_inferior): New routine pieced together, probably
5033 not quite working yet.
5034 (nindy_ops): New target_ops struct for nindy.
5036 * remote-vx.c: Use write_memory rather than target_write_memory
5037 to get error checking.
5038 (vx_add_file_command, vx_open): Use symbol_file_add rather than
5040 (vx_create_inferior): Use target_terminal_ours...
5042 * signame.c (_initialize_signame): Always initialize, since
5043 we need the table for things other than psignal.
5045 * solib.c (solib_add): Use symbol_file_add, not add_file.
5046 (solib_address): Return boolean result rather than struct
5047 pointer which nobody else knows the type of.
5049 * sparc-tdep.c, valops.c: Use write_memory rather than
5050 target_write_memory, to get error checking.
5052 * stack.c (locals_info, catch_info, args_info,
5053 get_selected_block, frame_command, up_command): Use
5054 target_has_stack, rather than have_inferior_p or
5057 * sun3-xdep.c (fetch_core_registers): Rewrite for new BFD regime.
5059 * symfile.h: New file, defining the interface between the
5060 generic and object-file-specific symbol reading code.
5062 * symtab.c: Move generic symbol-reading interface to symtab.c,
5063 from dbxread.c, coffread.c, mipsread.c, etc. Add symtab_fns
5064 table to map BFD targets to symbol-reading modules in GDB.
5065 Change index to strchr.
5066 (lookup_struct_elt_type): Use error() rather than hand-made
5067 simulations thereof.
5068 (lookup_partial_symbol): Speedup slightly when length == 0.
5069 (symbol_file_add): New function.
5070 (symbol_file_command): Call it.
5071 (symfile_open, symfile_init): New function.
5072 (add_file_target_command, add_file_addr_command): moved from
5075 * target.c (target_command): use target_kill.
5077 * target.h (target_files_info): Don't declare, never called
5080 * tm-sun2.h, tm-sun3.h (STACK_END_ADDR): Use system include
5081 files to determine stack end address.
5083 * valarith.c (value_x_binop, value_x_unop): Change error message
5084 to be more useful. Pass proper argument to value_struct_elt.
5086 * valops.c (value_assign): FIXME comment that long long
5087 bitfields will break here.
5089 * Makefile.dist: Add symfile.h, remote-nindy.c, remote-eb.c.
5090 Update `make saber_gdb' to work better.
5092 * TODO: A woman's work is never done.
5094 * cplus-dem.c, environ.c, inferior.h, infrun.c, inftarg.c,
5095 main.c, obstack.c, printcmd.c, remote-eb.c, remote-nindy.c,
5096 remote-vx.c, remote.c, solib.c, source.c, sparc-pinsn.c,
5097 sparc-tdep.c, sparc-xdep.c, symmisc.c, symtab.c, symtab.h
5098 target.c, terminal.h, tm-sparc.h, tm-sunos.h, utils.c,
5099 valops.c, valprint.c, exec.c: Lint.
5102 Wed Dec 12 23:44:15 1990 John Gilmore (gnu at cygnus.com)
5104 Continuing Intel 960 port merge of GDB.
5106 * Makefile.dist: Merge i960 "nindy-share" files. Rename
5107 malloc.h to gmalloc.h to avoid name conflicts in /usr/include.
5108 Don't ship gdb.dvi in tar file. Link gdb with init.o, not init.c.
5109 Wack over "make depend" so it handles files in subdirectories
5110 vx-share, nindy-share, bfd, and in the current directory.
5112 * blockframe.c (get_prev_frame_info): Remove fatal error
5113 if stack not defined.
5115 * core.c (core_open, core_detach): New functions that handle
5116 the old "core-file" command as "target core" and "detach" instead.
5117 (core_file_command): Call them.
5118 (core_xfer_memory): Use common routine xfer_memory.
5120 * dbxread.c: Include a.out.gnu.h, not system a.out.h.
5121 dbxread now uses bfd for everything but symbol reading itself.
5122 BFD internals are used to drag out the relevant file offsets.
5123 (partial_symbol_file_open): Change args all around for BFD.
5125 * symtab.c: Rename "value" to "val" everywhere, so we can
5127 (symbol_file_command): New command, moved from dbxread.c
5128 and coffread.c. It uses BFD to read the file, then vectors
5129 based on its type, to dbx or coff symbol readers.
5130 * symtab.h: Extern a few vars for symbol_file_command.
5132 * target.h: Breakpoint takes a char * save area, not a char **.
5134 * valprint.c (val_print): When unpacking bitfields, offset
5135 the address in gdb of the value, if it is declared with a shorter
5136 type. Remove the last "runtime kludge test" of host byte order.
5138 * utils.c: Remove old my_bfd_read routine.
5140 * stack.c (frame_info): Use target_has_stack. Print program counter
5141 register's actual name rather than "pc", since it's called the
5142 "ip" (instruction pointer) on the i960 (sigh).
5144 * target.c (target_command): Add command for selecting a target
5145 type and calling its open routine. This is used for initiating
5146 communication with a particular target, in a generic way.
5148 * tm-i960.h: Update for modern gdb. Remove semicolons from
5149 various macros. Handle reading struct return convention, and
5150 error-out attempts to return structs with the "return" command.
5151 Be sure gdb doesn't think we know how to call functions in the
5154 * i960-tdep.c: Rename FRAME_CHAIN_VALID and FRAME_FIND_SAVED_REGS
5155 to i960_xxx in lower case.
5156 (arg_address): Circumvent errors due to LOC_ARG_BLOCK
5157 not being defined yet.
5159 * remote.c (remote_open): Call start_remote to initialize
5160 wait_for_inferior during open.
5161 (remote_xfer_inferior_memory): Return length written rather
5164 * remote-vx.c (target_command -> vx_open): Use new generic
5166 * remote-eb.c, inftarg.c, exec.c: ditto.
5168 * infrun.c: Fix comments.
5169 (attach_program -> child_open): Use new generic target command.
5170 (wait_for_inferior): Clear saved register values before target_wait,
5171 so target_wait can set some of them if convenient.
5173 * infptrace.c (fetch_inferior_registers, store_inferior_registers):
5174 Return success indicator, not void.
5175 (child_xfer_memory): Avoid fetching initial word if we'll
5176 overwrite it anyway.
5178 * infcmd.c (attach_command): Use new generic target open routine.
5179 (_initialize_infcmd): Update doc on attach and detach commands.
5180 (do_registers_info): Merge in a byte-order problem as a FIXME
5183 * findvar.c (find_saved_register): Avoid problem in current frame.
5184 (read_relative_register): Ditto.
5185 (write_register): Convert byte order on the way out.
5187 * exec.c (file_command): Add.
5188 (add_to_section_table, exec_command): Use new bfd_map_over_sections.
5189 (xfer_memory): Common function between core_xfer_memory and
5191 (exec_xfer_memory): Use it.
5193 * pn-opcode.h: Document that a "PN" is a Gould PowerNode.
5195 * breakpoint.c, breakpoint.h, symtab.h, value.h, frame.h, utils.c,
5196 valops.c, stack.c, target.c, sparc-xdep.c, source.c, printcmd.c,
5197 infcmd.c, i960-pinsn.c, eval.c, defs.h: lint and gcc -Wall.
5199 Sun Dec 2 16:45:06 1990 John Gilmore (gnu at cygnus.com)
5201 Merge Intel 960 port of gdb, continuing...
5203 * dbxread.c (partial_symbol_file_open, partial_symbol_file_read,
5204 symbol_file_command): Pass from_tty arg to hush 'em up.
5206 * coffread.c (symbol_file_command): Avoid output if from_tty != 1.
5207 Add magic numbers for 960 COFF format.
5209 Fri Nov 30 09:18:20 1990 John Gilmore (gnu at cygnus.com)
5211 Merge Intel 960 port of gdb, from Intel "1.2" release.
5213 CHANGE_LOG entries from their port, which was based on

5217 Remove temp file if download is interrupted.
5219 Wed Aug 1 09:08:33 PDT 1990
5220 Now uses binary protocol to talk to NINDY.
5221 Old hex protocol (NINDY 2.13 and older) supported with -O switch.
5222 Times out after 5 seconds when trying to talk to NINDY.
5224 Tue May 29 12:54:49 PDT 1990
5225 Added variable baud rate (-b switch).
5226 Source code reorganization.
5228 Thu Apr 26 11:09:55 PDT 1990
5229 More cleanup of batch mode; specifically, execute "-s", "-e", and
5230 "-se" switches as soon as they are encountered on the invocation line.
5232 Fri Apr 20 13:47:15 PDT 1990
5235 Thu Apr 19 09:54:28 PDT 1990
5236 Add 'reset' command.
5238 Wed Apr 18 09:48:07 PDT 1990
5239 After opening remote tty, wait for 1 second to go by without input
5240 from it before trying to talk to NINDY (fixes problems with the
5241 Heurikon HK80/V960E).
5243 Mon Apr 4 16:33:05 PDT 1990
5244 Some output was not being suppressed in 'batch' mode.
5246 Thu Mar 22 15:31:11 PST 1990
5247 Ask user if old symbol table should be deleted when new file is
5250 Allow user to run a program downloaded before gdb960 was brought up.
5252 Correct "exec-file" help message for i80960 context.
5254 Correct bug in calculating user space address: could occasionally
5255 corrupt user program.
5257 Make sure to zero low-order bits in rip's because of bug in 960CA
5258 A-step part: could cause operation faults when "next"ing across
5261 Correct bug that made it impossible to get source line numbers for
5262 code loaded at addresses higher than 0x7fffffff.
5264 Wed Jan 10 12:43:22 PST 1990
5265 Open remote tty for exclusive use.
5267 Fri Jan 5 12:14:42 PST 1990
5268 Correct disassembly (CA manual was right after all):
5269 opcode for sysctl is 0x659
5271 Mon Oct 23 12:03:04 PDT 1989
5272 Use G960BASE and G960BIN environment variables to find 'sx' utility.
5274 Mon Oct 16 14:15:09 PDT 1989
5275 "sfr0"-"sfr31" should have been named "sf0"-"sf31"
5277 Mon Oct 2 15:56:31 PDT 1989
5279 Added 960CA disassembly support.
5281 To simplify maintenance:
5282 - eliminated use of symblic links on pinsn.c: use i960-pinsn.c
5284 - eliminated opcode.h: incorporates tables into i960-pinsn.c
5285 - moved 960-specific routines from i960-pinsn.c to i960-md.c
5286 - made disassembly interface identical to that in gdmp960.
5290 Wed Nov 28 21:32:48 1990 John Gilmore (gnu at cygint)
5292 * target.h: Allow targets to stack. Add target_has_memory,
5293 _registers, etc. Restructure memory access and "info files"
5294 to walk the target stack.
5295 * exec.c, core.c, inftarg.c, remote.c, remote-vx.c, remote-eb.c,
5296 target.c: Change tables to match target.h.

5301 * remote-eb.c: New memory regime, new info files.
5302 * remote-vx.c: New memory regime, new info files. Now use
5303 separate targets for VxWorks attachment to machine, and
5304 actually running a process under VxWorks, since one has
5305 stack & execution & regs and the other doesn't.
5306 * remote.c: New memory regime, new info files.
5307 * sparc-xdep.c (fetch_core-registers): New memory regime.
5308 * target.c: New routines and support for stacked targets,
5309 new memory regime, new info files regime.

5315 * exec.c (build_section_table): Iterate all sections and
5316 record what gdb needs to know about them.

5322 * source.c (find_source_lines): Use bfd_get_mtime.
5323 * dbxread.c: Quick changes to make it compile with new BFD.
5324 * utils.c (error): Avoid using bfd_error in generic routines.
5326 * core.c (core_fetch_registers): Get from the ".regs" section of
5328 * sparc-xdep.c (fetch_core_registers): Use the .regs info.
5330 * inferior.h (attach_flag): Export.
5331 * infcmd.c (run_command): use new target_create_inferior.
5332 * infrun.c (child_create_inferior): Don't return result.
5333 * Makefile.dist (VERSION): 3.91.4.
5335 Fri Nov 23 28:15:38 1990 John Gilmore (gnu at cygint)
5337 * breakpoint.c (bpstat_num): Handle breakpoints which have
5338 since been deleted, such as temporary breakpoints.
5339 infcmd.c (program_info): ditto.
5341 * core.c (core_file_command): Display the frame where the core
5346 * remote-vx.c (target_command): Merge in target command from
5347 targ-vx.c. A few other cleanups.
5349 * TODO, Projects: Lots more stuff to do...
5351 Fri Nov 23 18:15:38 1990 John Gilmore (gnu at cygint)
5353 Massive changes to wall off the remote-debugging interface
5354 behind a function vector. The port to handle VxWorks targets
5355 is also part of this.
5357 All files: Replace references to renamed functions,
5358 remove references to remote_debugging, remove references to
5359 have_include_file, have_core_file in favor of target_has_stack,
5360 target_has_memory, etc.
5362 * Modularize the breakpoint interface.
5363 breakpoint.h (BREAKPOINT_MAX): New define sets max length of
5364 a breakpoint instruction.
5365 breakpoint.c: struct breakpoint's shadow_contents now sized as
5367 (insert_breakpoints): Vector to target to install breakpoints.
5368 (remove_breakpoints): Vector to target here too.
5369 Remove REMOTE_SA_SPARC kludges and other remote_debugging.
5370 sparc-tdep.c (single_step): Use new breakpoint interface for
5371 the single-step breakpoints.
5372 mem-break.c (memory_insert_breakpoint, memory_remove_breakpoint):
5373 New file, contains routines to insert and remove breakpoints by
5374 reading out the old contents and later replacing them. This is
5375 how ptrace breakpoints work, and many remote systems as well.
5377 * tm-vxworks68.h: New config file, overrides a few things for
5378 Wind River's preferences.
5380 * target.h: New file, for transfer vector used to talk to the
5381 inferior (child, attached, core, exec, remote, etc). All accesses
5382 to the thing being debugged should come through these vectors.
5383 target.c: New file, routines to handle transfer vector.
5384 (various files): Add transfer vectors XXX_ops for the various
5385 targets and pseudo-targets (core files, etc) we support.
5387 * breakpoint.c (bpstat_stop_status): Further explorations of
5388 watchpoints and why things don't work all the time.
5389 (bpstat_alloc): New fn to allocate a bpstat and chain it.
5391 * config.gdb: Only add "source ${srcdir}/.gdbinit" to
5392 the local gdbinit if it doesn't already have it.
5394 * core.c (core_ops): add and install.
5395 Allow core debugging without exec file.
5397 * dbxread.c (free_and_init_header_files): Merge two fns.
5398 (end_symtab): Free named symbol table when a new version comes in.
5399 (read_dbx_symtab): Relocate all kinds of symbols with base
5400 address. First step toward handling different text, data, bss
5402 (add_file_addr_command): Renamed add_file_command.
5403 (add_file_command): Vector to remote handler.
5404 Add "load" as an alias for "add-file" command.
5406 * defs.h: Allow "volatile" to be used in non-ANSI; use it for
5407 non-returning functions.
5409 * exec.c: Add exec_ops, and push it as a target when an exec
5412 * infcmd.c (run_command): Pass executable file name and arg list
5413 separately when starting an inferior. Permit "run" when no exec
5414 file is specified, for VxWorks.
5415 (detach_command): Move to child_detach in inftarg.c.
5417 * inftarg.c: New file. Unix-child-specific routines, and the
5418 child_ops structure.
5420 * inferior.h (registers): Export "registers" as the way for
5421 target dependent register handlers to find gdb's local copy of
5422 the registers. Rename "stop_after_attach" to "stop_soon_quietly"
5423 since it is now used by places that want wait_for_inferior to
5424 handle the grunge but want to see every trap from the inferior.
5426 * inflow.c (create_inferior): Pull out, and merge into infrun.c.
5427 Eliminate remote_debugging hooks in terminal handling.
5429 * infrun.c: Replace start_inferior with child_create_inferior.
5430 Move all the hair of Unix shells and ptrace idiosyncracies into
5431 child_create_inferior, so remote handlers don't have to deal.
5432 Remove running_in_shell. Rename stop_after_attach to
5433 stop_soon_quietly, and use it in a few other places where we want
5434 to just call wait_for_inferior and get control back on the first
5435 trap. trap_expected now never takes a value > 1.
5436 (init_wait_for_inferior): Initialize static vars when a new
5439 main.c (gdbinit): Add new hook for .gdbinit file name, let
5440 it be overridden by config files as GDBINIT_FILENAME.
5441 (DEFAULT_PROMPT): Add new hook for overriding (gdb) prompt.
5442 Both of these are used for VxWorks gdb.
5444 mcheck.c: rename include file "gmalloc.c" to avoid problems
5445 with system include file "malloc.c".
5447 param-no-tm.h: New include file, same as param.h but does not
5448 include the default "tm.h" file. This is used in files where
5449 the target is known, e.g. remote-eb.c or sparc-xdep.c.
5451 param.h: Now just a shell that includes tm.h and param-no-tm.h.
5453 remote-vx.c: New file, VxWorks remote debugging support. Uses
5454 RPC routines that are shared with the target system, in directory
5457 remote.c: Vectorize remote interface.
5459 source.c: Globalize source_path, and make an alias "l" for "list"
5460 since we now have the "load" command.
5462 sparc-xdep.c: Use new param-no-tm.h.
5464 symmisc.c (free_named_symtab): Add new function from Wind River.
5465 However, ifdef it out for now while we think about what it should
5468 tm-sun3.h, xm-sparc.h, xm-sun3.h, xm-symmetry.h: Move
5470 the xm- file, and change its name to CHILD_PREPARE_TO_STORE, since
5471 non-Unix-children handle this with their own code in the target
5474 Makefile.dist: Roll version to 3.92.3. Add vx-share stuff to
5475 source and target lists. Add vx-share to default list of include
5476 directories. Add new files to src and target lists: mem-break,
5477 target, inftarg, remote-eb, remote-vx, targ-vx. Be sure the
5478 ${srcdir} versions of munch and createtags are used.
5480 * valops.c (find_function_addr): Split out of call_function.
5481 (call_function_by_hand): Rename call_function; this function
5482 calls functions in the target by laboriously patching the target
5483 word-by-word with the right stack, args, regs, etc.
5486 Mon Nov 5 17:29:10 1990 John Gilmore (gnu at cygint)
5488 Handle AMD 29000 a bit better.
5490 * remote-eb.c (readchar): Mask received char log to make it readable.
5491 (remote_start): Pass arguments down to executing program.
5492 Make startaddr unsigned.
5493 infrun.c (start_inferior): Accept args, pass them to
5495 infcmd.c (run_command): Pass args down to start_inferior.
5497 * tconfig/am29k-aout, tconfig/am29k-coff: New files specifying
5498 the target object file format.
5499 tm-29k.h: Pay heed to COFF_ENCAPSULATE.
5501 * am29k-pinsn.c (print_insn): Print 0x on hex numbers in disassembly.
5502 am29k-tdep.c (examine_prologue): Better checking of function prefixes.
5504 Sun Oct 7 18:20:45 1990 John Gilmore (gnu at cygint)
5506 * Makefile.dist (VERSION): Roll version to 3.91.9 and freeze.
5507 * TODO: We did a few things, we have more to do though.
5509 * xm-sparc.h (CLEAR_DEFERRED_STORES): Define.
5510 * inflow.c (inferior_died): Clear deferred stores.
5512 * Debug problems with dummy frames and calls to the inferior.
5513 * tm-sparc.h (PUSH_DUMMY_FRAME, POP_FRAME): Move to sparc-tdep.c.
5514 * sparc-tdep.c (do_restore_insn): Simplify.
5515 (sparc_frame_find_saved_regs): Simplify and fix what we find.
5516 (sparc_push_dummy_frame): Simplify and fix what we push.
5517 (sparc_pop_frame): Slightly more hair here, deciding whether
5518 we are restoring a saved PC or returning to a return address in %i7.
5519 * sparc-xdep.c (read_inferior_registers): Debug if valid reg is read.
5521 * utils.c (xmalloc, xrealloc): Return type depends on __STDC__.
5522 * symtab.h (xmalloc): ditto, for obstack_chunk_alloc.
5523 * obstack.h (chunkfun): ditto.
5524 * defs.h (xmalloc, xrealloc): ditto
5526 * utils.c (quit): Grab the terminal from the child if necessary.
5528 * inflow.c (term_status_command): Rename to term_info, change
5531 * sparc-pinsn.c (print_insn): Disassembly prefers real instructions.
5532 (is_delayed_branch): Speed up.
5533 * sparc-opcode.h: Add ALIAS bit to aliases. Fix up opcode tables.
5534 Still missing some float ops, and needs testing.
5536 * Support for input and output radixes other than base 10
5537 * defs.h (input_radix, output_radix): Declare.
5538 * expread.y (yyparse, parse_number): Handle changes of input
5539 radix, and ambiguous names-or-numbers in radixes >10.
5540 * printcmd.c (print_scalar_formatted): Print formatted hex
5541 numbers in varying column widths.
5542 * valprint.c (val_print): Use output_format to print scalar ints.
5543 (set_input_radix, set_output_radix, set_radix): Create.
5544 (set_output_radix): Set output_format from output_radix.
5545 (_initialize_valprint): add `set radix' but leave the others off.
5547 * main.c (execute_command): Let stupid questions be turned off.
5548 (_initialize_main): Handle "set stupidity", etc.
5550 * main.c, inflow.c, inferior.h, frame.h, command.c, defs.h,
5551 sparc-pinsn.c, sparc-xdep.c, value.h, valops.c, values.c: Lint.
5553 Tue Oct 2 11:20:02 1990 John Gilmore (gnu at cygint)
5555 * TODO, Makefile.dist, ChangeLog: Freeze for 3.91.8 release.
5556 bfd stuff is still screwed up, but with some manual work, it
5559 * breakpoint.c (bpstat_do_actions): Start over if a command
5560 proceeds the inferior, since the inferior will have stopped and
5561 will need to have its new stop-actions taken care of.
5563 * dbxread.c (read_struct_type): Expression gives Sun3 4.0.3
5564 compiler fits, simplify it.
5566 * gdb.texinfo (directory command): Doc new dir command.
5567 source.c (directory_command): "dir" now puts things on the front
5568 of the path, moves dups up front, and handles multiple names
5569 on the command line, inserting each one in order. It also
5570 blows away cached line and full_filename info.
5572 * stack.c (backtrace_command): Skip "more stack frames follow"
5575 * Change #ifndef HAVE_VPRINTF to #define MISSING_VPRINTF in
5576 xm-convex.h, xm-hp300bsd.h, xm-isi.h, xm-merlin.h, xm-news.h,
5577 xm-np1.h, xm-pn.h, xm-pyr.h, xm-symmetry.h, xm-umax.h, xm-vax.h.
5578 The only odd one was Gould NP1, which had defined vprintf to
5581 * Merge Ted Goldstein <tedg@Eng.sun.com>'s changes for epoch.
5582 printcmd.c (print_command_1): Pass 'inspect' flag down as a global
5583 variable, inspect_it.
5584 valprint.c (print_string, val_print): Use the global inspect_it
5585 to indicate whether to print in Epoch style or normal style.
5587 Mon Oct 1 23:55:26 1990 John Gilmore (gnu at cygint)
5589 * printcmd.c (call_command): add an alias for the "print" command
5590 which runs expressions and doesn't print the result if void.
5591 (print_command_1): implement it.
5593 * command.c: Remove #if 0'd code. Initialize all the fields
5594 in add_cmd (). Rename do_nothing_command to
5595 not_just_help_class_command, and make it externally visible.
5596 command.h: add user_commands to struct.
5597 * main.c (define_command): Don't overload c->function with a char
5598 string as well as a function pointer.
5600 * eval.c (evaluate_subexp): Reinstall tiemann changes to
5601 calling convention of value_struct_elt () that got dropped in
5604 * tm-sparc.h (FRAME_FIND_SAVED_REGS): move to sparc-xdep.c.
5605 sparc-tdep.c (sparc_frame_find_saved_regs): ditto.
5607 * tm-sparc.h (POP_FRAME): replace some constants with defines.
5609 * sparc-xdep.c (store_inferior_registers): defer stores to regs
5610 until a good time (e.g. when we are about to run the child),
5611 saving ptrace calls.
5612 * infrun.c (proceed): handle DO_DEFERRED_STORES.
5613 * tm-sparc.h: define DO_DEFERRED_STORES.
5615 * sparc-xdep.c (store_inferior_registers): when storing float
5616 registers, don't store stack regs too. When storing the SP,
5617 however, DO store the stack regs too. This fixes a bug in which
5618 the dummy frame is not recognized when a call_function finishes,
5619 because its frame pointer (in the stack regs) was never
5621 (read_inferior_registers): Mark WIM and TBR and FPS and CPS valid
5622 even though we don't know how to read them from an inferior.
5623 valops.c (call_function): Comment about storing SP.
5625 * infrun.c (save_inferior_status): Save away the original bpstat
5626 chain so it can be restored later. Install the copied version for
5627 use by whoever saved the status. It will be blow away by
5628 restore_inferior_status, and the original chain restored. This is
5629 important for people who have pointers into the original.
5631 * breakpoint.c, command.h, copying.awk, dbxread.c, defs.h,
5632 findvar.c, frame.h, obstack.h, obstack.c, inflow.c, value.h,
5633 main.c, printcmd.c, sparc-tdep.c, symtab.c, valprint.c: lint
5636 Fri Sep 28 20:32:46 1990 John Gilmore (gnu at cygnus.com)
5638 * Makefile.dist: Roll version to 3.91.8. Add bfd.h and bfdconfig.h
5639 temporarily to the makefile. Add am29k-opcode.h and WHATS.NEW.
5640 Add stuff.c and kdb-start.c to the OTHERS list for tar files.
5642 Fri Sep 28 19:12:12 1990 John Gilmore (gnu at cygint)
5644 * Merge Mike Tiemann's multiple inheritance changes from Sun.
5645 Store the baseclasses in a type struct starting from array element
5646 0 rather than from the unusual array element 1.
5648 dbxread.c: the above.
5649 (virtual_context): Add
5650 Read new debug information about which virtual function table
5651 a virtual function is from, and store it in fn_field.fcontext.
5653 symtab.h: Add fcontextt. Fix baseclass indices. Typo in
5654 TYPE_FN_FIELD_STATIC_P.
5656 symtab.c: the above.
5657 valops.c: the above. Handle pointer casts of object *'s.
5658 (search_struct_method): Add.
5659 (value_struct_elt): First arg is now a pointer to a value, and is
5662 valprint.c: the above.
5663 values.c (value_virtual_fn_field): Add type arg. Handle
5664 offsetting to the proper object when calling virtual fns.
5666 (baseclass_addr): Add valuep arg.
5668 * README: Document the current state of BFD config (missing).
5669 * TODO, ChangeLog, Makefile.dist: Roll version.
5670 * WHATS.NEW: Add summary of changes since 3.5.
5672 Thu Sep 27 16:23:12 1990 John Gilmore (gnu at cygint)
5674 * dbxread.c (read_struct_type): Clear bit vectors whenever
5676 symtab.c (B_CLRALL): define.
5678 * tm-sparc.h (STORE_RETURN_VALUE): Avoid clobbering types by
5679 using == rather than =. Huh... This fixes the dreaded problem
5680 wherein builtin_type_int becomes TYPE_CODE_FLT.
5682 * core.c (info_files): Show the inferior pid.
5684 * config.gdb: Avoid putting "dir" command into .gdbinit. GDB
5685 already knows how to look in the source directory.
5687 * Remove psymtab hair from many places. Remove duplicated code
5688 for searching symbol tables. Hide psymtabs from most places.
5689 Make it fast to get from a psymtab to its symtab.
5691 blockframe.c (blockvector_for_pc): Remove psymtab hair.
5692 coffread.c (psymtab_to_symtab): Rename to psymtab_to_symtab2.
5693 mipsread.c (psymtab_to_symtab): Rename to psymtab_to_symtab2.
5694 dbxread.c: export psymtab_to_symtab, make it work if called N times.
5695 (psymtab_to_symtab): Rename to psymtab_to_symtab2. Initialize
5696 new symtab completely. New psymtabs get symtab pointer
5697 initialized to zero. Remove MI warning printf.
5698 symtab.h: Comments. Add psymtab to symtab pointer.
5699 (PSYMTAB_TO_SYMTAB): New macro.
5700 symtab.c: use PSYMTAB_TO_SYMTAB. Add psymtab_to_symtab and export it.
5701 source.c: use PSYMTAB_TO_SYMTAB. Remove symtab version and
5703 stack.c (backtrace_command): Avoid pre-pass to read symbols, if
5705 (print_frame_info): Avoid special-casing symbols that have not yet
5708 * source.c (open_source_file): Quick path if we have already
5709 located the source file by its full name.
5711 * symtab.c (lookup_symbol): Use find_pc_symtab rather than
5712 find_pc_psymtab. When a name is found in the misc function
5713 vector, search the symbol table for its mangled name, not the
5714 name that the user typed.
5716 * bfd.h: Fix missing comment terminators, make #endifs match.
5718 * valarith.c (value_less): Handle unsigned int comparisons.
5719 Add FIXME about pointer compares, which assume host and target
5720 pointers are the same.
5722 * command.c (do_nothing_command): lint
5723 dbxread.c: lint. Remove sort_syms. Document C++ visibility info,
5724 fix comments on debug symbol format for visibility. Actually set
5725 visibility of symbols.
5726 main.c (echo_command): lint; use <readline/history.h>.
5727 tm-sparc.h (FRAME_FIND_SAVED_REGS): lint
5728 obstack.h (_obstack_blank): Rearrange pointer math to avoid
5729 pointing past end of allocated memory; saber complains.
5730 obstack.h: Declare the external functions that we use.
5731 valarith.h: use <string.h>
5732 solib.c (solib_add): lint.
5734 Fri Sep 21 17:05:19 1990 John Gilmore (gnu at cygint)
5736 * main.c (initialize_main): Default info_verbose to off, now that
5737 symbol reading is fast.
5738 (quit_command): Avoid clobbering exec_bfd while quitting.
5740 * Initial BFD (binary file diddling library) merger:
5741 coffread.c: Change AOUTHDR to struct exe_hdr.
5743 core.c: initialize initialized data at compile time.
5744 (core_file_command): Move from coredep.c, convert to bfd.
5745 (xfer_core_file): Convert to bfd.
5746 exec.c (exec_file_command): use bfd routines.
5748 mips-tdep.c: Remove exec_file_command and friends.
5751 * coredep.c: (fetch_core_registers) Convert core_file_command to
5752 fetch_core_registers.
5753 mips-xdep.c, sparc-xdep.c, sun3-xdep.c: ditto.
5755 * utils.c: (error): Bogus crap, FIXME, to print bfd errors.
5756 (my_bfd_read): More bogosity, which I don't think we call.
5757 (program_name): Remove this atrocity asap!
5759 Wed Sep 19 13:36:41 1990 John Gilmore (gnu at cygint)
5762 values.c: allocate_repeat_value was not clearing the
5763 optimized_out field.
5764 (value_static_field): minor stylistic fix (wrong macro was used).
5765 valops.c (value_struct_elt_for_address): didn't work for C++
5768 * signame.c (_initialize_signame): Initialize signal names once.
5770 * breakpoint.h, command.c, copying.awk, defs.h, environ.c,
5771 exec.c, frame.h, infcmd.c, inferior.h, main.c, munch, sun3-xdep.c,
5772 symtab.h, tm-29k.h, valprint.c, value.h, values.c: Lint.
5774 * remote-eb.c: Support user-settable baud rates on the serial port.
5776 * tm-sun3.h (PREPARE_TO_STORE): fix typo.
5778 Fri Sep 14 13:28:29 1990 John Gilmore (gnu at cygint)
5780 * tconfig/sun3os4: Remove warning about native assembler,
5781 since it also occurs in the xconfig file.
5783 * findvar.c (registers): Allocate some slop after `registers'
5784 to prevent stray accesses from trashing the next variable.
5786 * tm-68k.h (REGISTER_BYTES): Allocate the right number of bytes
5787 on the sun-3, by changing the #ifdef from `sun3' (which is not
5788 defined by cc) to `sun'. Symptom was trashed builtin_type_XXX
5789 vars, which happened to follow `registers' in the executable.
5791 * readline/history.c (history_search): Heed gcc-2's advice
5792 and parenthesize && inside ||).
5794 * am29k-opcode.h, am29k-pinsn.c, am29k-tdep.c, remote-eb.c,
5795 tm-29k.c: Insert FSF copyright headers.
5797 * remote-eb.c: Better comments.
5799 * Makefile.dist: Update to 3.91.6.
5800 * TODO: note PREPARE_TO_STORE problem.
5802 Thu Sep 13 09:52:33 1990 Jim Kingdon (kingdon at cygint)
5804 * stack.c (frame_info): Only use FRAME_FIND_SAVED_REGS if defined.
5806 * remote.c: Wrap the whole file in #if !defined (SPECIAL_REMOTE).
5808 * infrun.c (wait_for_inferior, at end): Don't set up
5809 prev_* if the inferior no longer exists.
5811 * inferior.h (CALL_DUMMY_LOCATION): New macro, to replace
5812 CANNOT_EXECUTE_STACK.
5813 valops.c (call_function): Use it.
5815 * tm-convex.h: Add CALL_DUMMY_LENGTH for use by PC_IN_CALL_DUMMY.
5817 * inferior.h (PC_IN_CALL_DUMMY): New macro.
5818 infrun.c (wait_for_inferior, 2 places): Use it.
5820 * values.c (value_being_returned): Only use
5821 EXTRACT_STRUCT_VALUE_ADDRESS if defined.
5823 * Move PREPARE_TO_STORE from xm-sun3.h to tm-sun3.h to do the
5824 right thing for remote-eb.c.
5826 * sun3-xdep.c: Remove extraneous call to remote_store_registers.
5827 * sun386-xdep.c, hp300hpux-xdep.c, sparc-xdep.c: Ditto.
5829 * blockframe.c: Put get_frame_saved_regs inside #if !defined
5830 (FRAME_FIND_SAVED_REGS).
5832 * findvar.c ({fetch,store}_registers): Check for
5833 REMOTE_{FETCH_STORE}_REGISTER macro.
5835 * findvar.c (get_saved_register): Add argument lval and
5836 change meaning of argument addr.
5837 findvar.c: Change calls to get_saved_register to reflect
5838 new calling convention.
5839 valops.c (value_assign): Use get_saved_register instead of
5840 find_saved_register.
5842 Sun Sep 2 12:40:20 1990 Jim Kingdon (kingdon at cygint.cygnus.com)
5844 * coffread.c (read_one_sym): Make temp_aux an AUXENT, not
5845 an (uninitialized) pointer to one. Use "&" when passing it
5848 Fri Aug 31 22:57:54 1990 Jim Kingdon (kingdon at cygint.cygnus.com)
5850 * coffread.c (getfilename): Use DGUX x_offset and x_name if
5853 * coffread.c (symbol_file_command): Put semicolon after
5855 Put safe_to_init_tdesc_context in #if defined (TDESC).
5856 Put #ifdef TDESCs in 1st column for non-ANSI cpp's.
5857 coffread.c: #include <sys/stat.h>.
5858 (read_coff_symtab): Typo: in_source_files -> in_source_file.
5859 Add missing ')' in check for "lc%" and friends. Remove
5861 Declare read_one_sym() at top of file.
5862 (read_file_hdr): Put in extra #ifdefs so MC68MAGIC and
5863 MC68WRMAGIC can have the same value without causing a duplicate
5866 Thu Sep 13 15:55:36 1990 John Gilmore (gnu at cygint)
5868 * Allow a Makefile to be built without building the
5869 tm and xm file links that screw up builds in subdirectories.
5870 This is done with `config.gdb none', then you can do things
5871 like `make gdb.tar.Z'.
5872 * tconfig/none: Config file for no target system
5873 * xconfig/none: Config file for no host system
5874 * config.gdb: If no TM or XM files are called out by the
5875 host or target file, don't make links for them.
5877 * cplus-dem.c: Add documentation.
5879 * dbxread.c (read_ofile_symtab): Turn a fatal error into a
5880 simple error, so the user's gdb doesn't crash due to some object
5881 file problem (e.g. somebody is rebuilding the file out from under
5884 * printcmd.c (print_address_symbolic): demangle the symbol.
5886 * Makefile.dist (OTHERS): Remove tdesc-lib because it has
5887 Motorola copyrights in it. Make "make gdb.tar.Z" work.
5888 (alldeps.mak): sort and uniq all results from this; duplicates
5889 hose gdb.tar.Z link building. Remove RCS files from
5890 tconfig and xconfig. Add config files for sun386. Add
5891 a few odd files to OTHERS and HFILES.
5893 Mon Sep 10 21:20:24 1990 John Gilmore (gnu at cygint)
5895 * Makefile.dist: Pull solib.c to tconfig/sun?os4.
5896 Roll version number to 3.91.5. Make lint work in bindir.
5898 * README: Document cross-debugging and new file structure.
5900 * blockframe.c: Lint. Include "value.h" to declare read_register.
5901 (find_pc_partial_function): remove duplicate line.
5903 * command.h: Lint. Declare error_no_arg and dont_repeat.
5905 * tm-news.h: Remove inadvertently duplicated stuff.
5907 * mipsread.c: Remove cache_pc_function stuff, now done cleanly.
5908 Clean up usage of misc_function_type. Declare some CORE_ADDRs.
5910 * config.gdb: Allow `config.gdb host target' form. Clean
5911 up previous change that printed bogus messages when you just said
5914 * core.c: #include "command.h" for lint.
5917 * main.c: Remove some casts of enums. Lint.
5924 * printcmd.c (initialize_printcmd): Fix thinko in inspect cmd.
5926 * sparc-tdep.c (isannulled): Take instruction as parameter, don't
5927 read it from memory. This will allow us to save ptrace calls
5928 eventually. Changed caller single_step too.
5930 * sparc-xdep.c (fetch_inferior_registers): Avoid reading regs
5931 that we aren't going to use, saving many ptrace calls, especially
5932 when watchpointing or single stepping. Use some #define's for
5934 (store_inferior_registers): Ditto.
5935 (core_file_command): Use some #define's for constants.
5937 * tm-sparc.h: Add #define's for some register numbers, so we
5938 can eliminate the use of random constants in sparc-xdep.c.
5940 * stack.c (frame_command, print_frame_info, up_command,
5941 down_command) Remove frame_changed, since it
5942 causes a bug and doesn't seem to do anything useful. In some
5943 places it was used as a flag, in others as a stack level (?).
5945 * utils.c: Use MISSING_VPRINTF rather than HAVE_VPRINTF, so the
5946 default is to use the portable (vprintf) version rather than the
5948 * xm-news.h (MISSING_VPRINTF): Add.
5950 * valprint.c (val_print): Demangle fancy vtbl printouts. Lint.
5952 Sat Sep 8 00:24:12 1990 John Gilmore (gnu at cygint)
5954 * Remove stuff that forces -Bstatic linking of gdb, and warnings
5955 about linking debugged programs -Bstatic in the sun?os4 config
5956 files in tconfig and xconfig subdirectories.
5958 * main.c (main): Remove unreached exit(0) now that we exit
5961 * Create TODO file for online bug list. There are too many
5962 "little" bugs to keep track of on paper.
5964 * Change Projects file to refer to bug-gdb@cygnus.com
5965 rather than kingdon@ai.
5967 Fri Sep 7 23:35:15 1990 John Gilmore (gnu at cygint)
5969 * Makefile.dist (VERSION): 3.91.4 now.
5971 * symtab.c (init_misc_bunches): Rename from init_misc_functions.
5972 (condense_misc_bunches): Add sanity check that misc_count is
5973 the same as the number of symbols in the bunch.
5975 * coffread.c: rename init_misc_bunches. Pass an argument
5976 to condense_misc_bunches (a zero).
5978 * dbxread.c (partial_symbol_file_read): Call init_misc_bunches
5979 every time we are called; don't rely on our caller to do it.
5980 (add_file): Remove call to init_misc_bunches.
5982 * mipsread.c: Only warn, don't error, if unknown symbol types.
5983 This keeps an old gdb from falling on its face if it sees newly
5984 extended symbol info. Rename init_misc_bunches.
5986 Fri Sep 7 22:58:15 1990 John Gilmore (gnu at cygint)
5988 * Merge in changes from Per Bothner for DECstations and other
5989 MIPS stuff. The rest is Bothner speaking:
5991 The next message is a merger of Alessando Forin's mips port with
5992 mine. I've tried to use my good if biased judgment to get
5993 the best of both. It *does* need testing.
5995 Some of the changes are general, *not* mips-specific.
5998 Didn't believe in little-endian bit order.
5999 There are still inconsistencies about whether flags
6000 like BITS_BIG_ENDIAN are integer (#if ...) or
6001 boolean (#ifdef ...). I tried to paper over them.
6003 dbxread.c,coffread.c,mipsread.c,symtab.c,symtab.h:
6004 Moved some misc_function code that was common to
6005 {dbx,coff,mips}read.c to symtab.c.
6006 In the process, I think I cleaned things up a bit.
6007 At the same time, moved obsavestring and obconcat to symtab.c.
6010 Removed obsolete condense_addl_misc_bunches (use
6011 condense_misc_bunches(1) instead).
6014 Needed to include <sys/dir>, at least on DECstations.
6016 valops.c, mips-tdep.c, tm-mips.h:
6017 Added PUSH_ARGUMENTS macro to support funny argument-pushing
6018 conventions (when STACK_ALIGN is insufficient).
6019 Needed on mips, where doubles need 8-byte alignment,
6020 but ints only need 4.
6023 Removed cruft that was not being used.
6024 Merged in many fixes (most from Frank Yellin, fy@lucid.com).
6027 Print $ before register-names (I think that makes things a little
6029 Never print two instructions, even if one delays.
6030 Removed hex-disassemble set_cmd. (This is not mips-specific,
6031 so I think the argument is whether it is generally worthwhile or not.
6032 I'm inclined to think not, given how easy it is to
6033 convert between radixes in gdb.)
6036 This is basically Alessando's code.
6037 It doesn't use obstacks; I changed it to use obstacks
6038 in a few minor places where using malloc causes a
6039 memory leak. (Probably, more places could/should be changed.)
6040 I added record_misc_function where it was missing.
6041 In symbol_file_command and add_file_command, I tried
6042 to make the code consistent with more recent versions.
6043 Minor sylistic changes in parse_procedure.
6044 Make a .gdbinfo. psuedo-symbol point back to the real
6045 procedure symbol (using the isym field).
6048 This is basically from my port, but with a lot of details
6049 and a number of routines merged in from Alessando's version.
6050 I basically used my code "raw" backtrace (use heuristics
6051 from the actual code, rather than symbol table info) - though
6052 the idea is Alessandro's. I feel my code is a little cleaner
6053 here, particularly in being a little more flexible, such as being
6054 able to handle gcc-produced code (which it now can).
6055 It also doesn't do frame caching (which is not useful
6056 more recent gdb versions).
6057 I also used my code for push_/pop_dummy, more or less.
6058 I tried to incorporate AF's code for testing sigtramp
6059 while backtracing; I probably got it wrong.
6060 Added mips_print_register, which tries to scrunch as much
6061 information as possible on a screen...
6062 Removed the skip-prologue set_cmd. As with hex-disassemble (see
6063 under mips-pinsn.c), I don't see anything mips-specific here,
6064 and I don't see it being all that useful anyway.
6067 Added a $fp psuedo-reg distinct from $fp (nice for gcc).
6068 Use more register names (rather than hard-cases numbers).
6070 Thu Sep 6 18:33:15 1990 John Gilmore (gnu at cygint)
6072 * Hack up 3.90.11 changes:
6074 * Makefile.dist (depend): parameterize $(GCC).
6075 Add solib.c and solib.o.
6076 (readline): Fix vpath for both absolute or relative SRCDIR.
6078 * blockframe.c: Fix from Schaefer@asc.slb.com for shared libs.
6079 Also, let the part I didn't understand at least compile so
6080 I can test the rest. FIXME.
6082 * dbxread.c: Fix thinko using strcmp.
6083 (init_psymbol_list): declare static.
6084 (partial_symbol_file_open): Comment cleanups better, avoid
6085 cleaning up the string table since the caller will do that.
6086 Move the stat for mod time into symbol_file_command, temporarily.
6087 (There should be a mod time for each symbol file, eventually,
6088 to control its rereading. FIXME.)
6090 * infptrace.c (PT_WRITE_D): use same value as PT_WRITE_I for
6091 SunOS, which gives error for shared libs otherwise. (From
6092 Schaefer, probably FIXME needs work for portability.)
6094 * solib.c: Move #include "param.h" to work.
6095 Lowercase all the Uppercase Letters In the Messages.
6096 (find_solib): Clean up inferior_so_name for debug printouts.
6097 Allow no argument, to mean all shared libraries.
6099 * symmisc.c: include param.h to get CLEAR_SOLIB.
6101 Wed Sep 5 18:00:08 1990 John Gilmore (gnu at cygint)
6103 * Merge in Kingdon's changes from FSF: the diffs from 3.90.9
6104 to 3.90.11. ChangeLog entries below are from this.
6106 Wed Jun 13 09:17:39 1990 Jim Kingdon (kingdon at mole.ai.mit.edu)
6110 * Makefile.dist (HFILES): Add tm-sunos.h.
6112 Tue Jun 12 16:15:26 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
6116 * Makefile.dist (gdb.tar.Z): Change linking of config so it works.
6118 Thu Jun 7 16:22:27 EDT 1990 Jay Fenlason (hack@ai.mit.edu)
6120 * sparc-opcode.h Added single-operand version of rett.
6122 Mon Jun 4 18:12:31 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
6124 * m-sparc.h (REG_STRUCT_HAS_ADDR, STRUCT_ARG_SYM_GARBAGE):
6125 Put parens around gcc_p in expansion.
6127 Thu May 24 15:44:51 1990 Jim Kingdon (kingdon at mole.ai.mit.edu)
6129 * utils.c (lines_to_list): Return 10 if lines_per_page == 0.
6131 Wed May 23 16:36:04 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
6133 * Changes for Sun shared libraries:
6134 blockframe.c (find_pc_partial_function): If a non-text symbol
6135 is found, set *address = pc - FUNCTION_START_OFFSET.
6136 breakpoint.c (insert_breakpoints) [DISABLE_UNSETTABLE_BREAK]:
6137 Disable breakpoints instead of giving an error.
6138 source.c (select_source_symtab): Initialize cs_pst.
6139 symmisc.c: Call CLEAR_SOLIB if defined.
6140 symtab.h: Make text{low,high} CORE_ADDR not int.
6141 (psymtab): New field addr.
6143 dbxread.c: Move DECLARE_FILE_HEADERS outside functions.
6144 (record_misc_function): Give correct type for N_DATA symbols.
6145 (condense_misc_bunches): do "misc_function_count = j" regardless
6147 Take code which is shared between symbol_file_command and
6148 add_file_command and put it into partial_symbol_file_{open,read}.
6149 Split add_file_command into add_file_command and add_file.
6150 Make psymtab_to_symtab read in the string table if the file
6152 Two new parameters to read_dbx_symtab and start_psymtab.
6153 tm-sunos.h: New file.
6155 Tue May 22 17:43:03 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
6157 * infcmd.c: Change cont_command to continue_command and "cont"
6160 Mon May 21 14:41:41 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
6162 * breakpoint.c (enable_breakpoint): Get value of watchpoint.
6164 * defs.h [sparc]: Use <alloca.h> regardless of __GNUC__.
6166 * values.c (USE_STRUCT_CONVENTION): Check for structures of
6167 size 1,2,4,8 rather than size < 8.
6169 * dbxread.c (dbx_lookup_type): Do f->length *= 2 as many times
6170 as necessary, not just once.
6172 * sparc-opcode.h: Add a bunch of new opcodes which Sun as supports.
6174 Thu May 17 15:04:09 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
6176 * {t,x}m-sun386.h, sun386-xdep.c, {x,t}config/sun386
6178 * tm-news.h: Add CALL_DUMMY_*.
6180 * tm-68k.h: Remove duplicate comment at FRAME_FIND_SAVED_REGS.
6182 * config.gdb: In list_host, list_target, use ${i}, not $i.
6184 Tue May 15 21:27:12 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
6186 * source.c (find_source_lines) [BROKEN_LARGE_ALLOCA]: Use xmalloc.
6188 * sparc-opcode.h: Change all store floating-point state register
6189 instructions to have the right match & lose fields.
6191 Sat May 5 12:39:18 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
6193 * Makefile.dist: Move -I${srcdir} to GLOBAL_CFLAGS and pass
6195 config.gdb: If srcdir != ., create readline directory and
6196 copy a makefile into it.
6198 * wait.h, infrun.c: Change WRETCODE to WEXITSTATUS for
6199 consistency with POSIX.
6201 * breakpoint.c (bpstat_stop_status): Disable watchpoint
6202 when we exit its exp_valid_block.
6204 Tue Sep 4 11:46:46 1990 John Gilmore (gnu at cygint)
6206 * Makefile.dist: Bump version to 3.91.3.
6208 * Clean up handling of breakpoint commands (somewhat).
6209 Prompted by Tiemann bug report "cont 10" doesn't work any more.
6211 inferior.h: Add breakpoint_proceeded to inferior status struct
6212 and globals; save it and restore it.
6213 (clear_breakpoint_commands): Cleanup, remove old #define.
6215 infrun.c (clear_proceed_status): Set breakpoint_proceeded.
6216 (save_inferior_status, restore_inferior_status): handle it also.
6217 (proceed): Remove earlier code that set breakpoint_proceeded.
6218 It is now set only in clear_proceed_status.
6219 (clear_proceed_status): Cleanup, use bpstat_clear rather
6220 than clear_breakpoint_commands. No callers need the stop_bpstat
6221 between clear_proceed_status and proceed.
6223 infcmd.c: Add breakpoint_proceeded definition and comment.
6224 (cont_command, jump_command, signal_command): Move call to
6225 clear_proceed_status right next to call to proceed.
6227 breakpoint.c (bpstat_do_actions): Avoid clobbering our
6228 caller's argument while running down the chain of breakpoints.
6229 Use new variable "breakpoint_proceeded" to determine when
6230 a command that it executes moves the inferior past the
6232 (bpstat_clear): Handle NULL argument.
6233 (bpstat_clear_actions): Avoid useless call to
6234 breakpoint_auto_delete.
6235 (delete_breakpoint): Clean up bpstat's that are pointing to
6236 the deleted breakpoint from the stop_bpstat chain.
6237 (breakpoint_auto_delete): Simplify.
6239 * Clean up handling of EOF, error on stdin, etc. This was
6240 prompted by a network problem that caused gdb to go into an
6241 infinite loop filling up its malloc'd memory.
6243 main.c (return_to_top_level): Cleanup: call bpstat_clear_actions,
6244 not clear_breakpoints_commands, which is now gone.
6245 (main): If command_loop returns (e.g. from EOF on stdin), do
6246 a quit_command (looping back to command_loop if quit_command
6247 doesn't really quit).
6248 (command_loop): check result from command_line_input and
6249 exit if it returns NULL, rather than passing the NULL to
6251 (gdb_readline): Free malloc'd result space before returning
6254 * utils.c (query): Handle C-d to mean "yes", just as if the
6255 input was not a terminal. Also avoid infinite loop if EOF
6256 occurs in mid-input-line before newline. This allows
6257 query to be used at EOF on stdin with reasonable results.
6259 * infrun.c (proceed): Set breakpoint_proceeded.
6261 * values.c (value_as_long): Avoid infinite recursion for enums.
6262 (_initialize_values): Fix typo in help msg (kingdon).
6264 * Makefile.dist (RL_LIB): Use RL_LIB_DEP for dependencies,
6265 RL_LIB for linking. This allows -lreadline for linking
6266 and nothing for dependencies, once readline is a real library.
6268 * config.gdb: Jim Kingdon: give useful error message if the
6269 host or target type is not recognized.
6271 * defs.h (alloca): SPARC <alloca.h> does not declare alloca,
6272 it just defines it. Dumb, but deal with it.
6274 * Jim Kingdon suggests:
6275 in xconfig/sun3os4, CFLAGS should be XM_CFLAGS.
6277 Wed Aug 29 18:03:27 1990 John Gilmore (gnu at cygint)
6279 * Makefile.dist (VERSION): Bump version # to 3.91.2.
6281 * Clean up Bothner's changes.
6283 * blockframe.c (clear_pc_function_cache): New function.
6284 * blockframe.c: remake cache_pc_function_* static.
6285 * dbxread.c (symbol_file_command): remove references to
6286 cache_pc_function_* variables.
6287 * dbxread.c (read_struct_type): Use VOFFSET_STATIC.
6288 * printcmd.c: Avoid kludging a global variable (addressprint)
6289 to avoid printing the address of a string twice. Instead,
6290 pass the format letter 's' down low enough that it can be seen
6291 to avoid this problem.
6292 (print_formatted): Pass format arg to value_print.
6293 (restore_addressprint): Remove function.
6294 (do_examine): Avoid hacking addressprint, cleanups and such.
6295 (print_frame_args): Add a comment to a Bothner change.
6296 * symtab.h: define VOFFSET_STATIC and use it instead of "-1".
6297 * symmisc.c (free_all_symtabs): Call clear_pc_function_cache
6298 to wipe out the values cached in blockframe.c.
6299 * symtab.c (find_method): Add comment saying how big you must
6300 allocate to be "big enough". Per being terse again.
6301 * valprint.c (val_print): Handle format letter "s" to print
6302 strings without addresses. Add comment to vtbl printing code
6303 which casts with wild abandon. Rearrange reference-printing
6305 @0xaddr: value (print w/addressprint)
6306 value (print w/~addressprint)
6307 @0xaddr (parameter lists w/addressprint)
6308 or nothing (parameter lists w/o addressprint)
6310 Tue Aug 28 10:47:18 1990 John Gilmore (gnu at cygint)
6312 * Merge more changes from Per Bothner:
6314 Gdb's handling of TYPE_CODE_REF was so counter-C++ (and otherwise
6315 annoying) that I tried to improve it. Here are my suggestions.
6317 These patches all attempt to handle TYPE_CODE_REF (as in C++) better.
6320 Do automatic de-reference when taking the address of a reference.
6322 Don't deref_ref when printing parameter lists.
6324 More attempts at treating refernences properly.
6326 In val_print, if deref_ref==0, don't print dangling " = ".
6328 Add COERCE_REF macro, which de-references an REF.
6330 * Merge changes from Per Bothner:
6332 * Fixed (Sony news)-specific configuration problems.
6333 * Fixed other problems with using vanilla pcc and libc (enum problems;
6334 assumption that vsprintf exists).
6335 * Some major speed-ups (finc_pc_partial_function now caches a match;
6336 parsing avoids duplicate symbol_lookup calls).
6337 * Changed handling of baseclasses (no longer use baseclasses field
6338 of struct type, use the first n_baseclasses fields instead).
6339 * Various minor changes/fixes, most C++-related.
6342 Cache the most previous match from find_pc_partial_function.
6343 (Save both low and high ends of matching function's pc range.)
6344 This speeds up the loop of infrun.c:wait_for_inferior quite
6345 a bit, and makes step/next commands much zippier.
6347 Added an enum->int cast (otherwise, some compilers barf).
6349 No longer set baseclass offset to 0, since multiple
6350 inheritance now mostly works.
6351 Added a number of casts, to shut up compiler warnings
6352 (after stabs where made enums, not ints).
6353 When discarding a symbol table (in symbol_file_command),
6354 must clear the cache introduced in blockframe.c.
6355 Don't convert $vtbl_ptr_type to vtbl any more.
6356 Get rid of TYPE_BASECLASEES and baseclass_vec (see also symtab.h).
6357 Mask off sign bit emitted by g++ for virtual table offset.
6358 Set voffset to -1 (not 1) for static member functions.
6360 Changed parsing/lexing of names to avoid doing symbol lookup twice
6361 (once when lexing to determine symbol class, once for real).
6362 Now only call symbol_lookup once. Fields of 'this' win especially big.
6364 Subpress printing addr twice in the case of 'x/s addr'.
6366 lookup_basetype_type is no longer used.
6367 Add find_methods as recursive helper function to decode_line_1.
6368 This allows multiple inheritance to work.
6369 Also, once one or more matches has been found, do not look in
6370 base-classes. (Baseclass methods would be overridden, anyway.)
6372 Removed baseclasses array in struct type.
6373 Instead of using baseclasses[i], use fields[i-1].
6374 Added virtual_field_bits[i] to indicate if the i'th baseclass is virtual.
6375 Changed sign convention of voffset (previous was inconsistent).
6377 Some macros (CALL_DUMMY and relatives) were missing. Put them back.
6379 Used to assume existence of vsprintf. Re-written to not need it
6380 if HAVE_VPRINTF is undefined.
6382 typecmp was too pessimistic. Made it less so.
6384 Don't print space after address.
6385 If vtable points to a misc symbol (with 0 offset), print it,
6386 since that indicates the actual class of the object.
6387 Changed ype_print_derivation_info to use new inheritance
6388 scheme (without baseclasses vector).
6390 In value_primitive_field, fixed some bugs left over from previous set of fixes.
6391 Also, changes needed because TYPE_BASECLASSES were removed.
6393 REGISTER_U_ADDR didn't work for PC. Rewrote to use an array.
6395 Tue Aug 21 20:08:54 1990 John Gilmore (gnu at cygint)
6398 If there is no path set, and the symbols don't indicate what directory
6399 a file was compiled in, look in the current directory. But either
6400 a path or a known compilation directory will prevent this.
6403 Three independent bug fixes:
6404 * Remove the #if 0 block that breaks some stuff.
6405 * SunOS 4.1 fixed the promoted-parameter-wrong-addr bug in Sun C;
6406 adapt gdb to either SunOS 4.0.* or 4.1.
6407 * MAX_OF_TYPE and MIN_OF_TYPE thinko. By tedg@sun, I think.
6410 Instantiate the class T when looking for methods in it. (Tiemann@sun)
6413 (type_print) Demangle the name being printed.
6414 (type_print_base) Handle botched demangling without coredump (tiemann).
6417 (check_stub_method): Document routine.
6418 (tiemann) fix bug for no-arg functions
6419 Avoid clobbering beyond end of malloc'd storage.
6420 Terminate the argument list properly.
6422 Sat Aug 18 01:29:59 1990 Per Bothner (bothner@cs.wisc.edu)
6424 * Changes merged by John Gilmore:
6427 In breakpoint_1, use new print_address_symbolic instead
6428 of find_pc_partial_function. (This forces use of assembler-level
6429 addresses, and avoids misleading non-mangled source-level names.)
6431 Generalize ansi argument such that -1 means skip arglist totally.
6432 Removed global variable print_ansi_qualifiers (which made
6433 code non-reentrant), in favor of extra explicit arguments
6434 to internal routines.
6436 Add new helper function print_address_symbolic.
6437 Use find_pc_misc_function instead of find_pc_partial_function
6438 (since we want assembler-level symbols here).
6440 Print unknown function as just "f (...)", not "f (...) (...)".
6441 Use new fputs_demangled explicitly.
6443 Fixed a typing violation (problem: value.h cannot be imported
6444 without renaming many variable in this file).
6445 lookup_symbol: If no matching misc_func, look for a C++-mangled name.
6446 decode_line_1: Moved forward some never-reached code.
6447 Made decode_line_2 skip function prologues correctly.
6449 fputs_filtered should not demangle by default.
6450 Add new fputs_demangled to demangle on demand..
6452 Change value_struct_elt to use value_primitive_field (using recursive
6453 utility function search_struct_field). This allows foo.bar to work
6454 for multiple inheritance (so far only for data fields).
6455 Change check_field in the same way (recursive helper function
6456 to support multiple inheritance).
6457 (Note: there are more of these problems that I haven't fixed.
6458 Any code that says TYPE_BASECLASS (t, 1) is probably wrong.)
6459 value_of_this: 'this' symbol name is now just "this", note "$this".
6461 Don't print static members.
6462 Avoid printing "members of <type>" if there are none.
6463 Simplified type_print_derivation_info by merging duplicate code.
6464 Remove useless blank lines in type_print_base (ptype command).
6466 Added declaration of new routine value_primitive_field.
6468 Added value_primitive_field which is generalized version of
6469 value_field that can handle multiple inheritance (non-zero offsets etc).
6470 Re-implemented value_field to call value_primitive_field.
6472 Fri Aug 17 23:33:44 1990 John Gilmore (gnu at cygint)
6474 * infcmd.c -- insert else to avoid 'delete env' coredump when you
6475 delete the whole environment. Karl Berry reported the bug.
6476 * source.c - fix openp to avoid //'s in filenames, which
6477 trigger an Emacs bug causing it to not be able to find files
6478 when running gdb in a window.
6479 * dbxread.c - zap the #if 0 that botches the add-file code.
6480 It seems to work a lot better without all the code commented out.
6482 Fri Jul 20 16:58:46 1990 John Gilmore (gnu at cygnus.com)
6484 * Merge Tiemann's and Ted Goldstein's changes, detailed below,
6487 Tue Jul 17 19:34:33 1990 Ted Goldstein (tedg at golem)
6489 * Makefile - added a ${CFLAGS} to a couple of entries,
6490 added remote-sa.sparc.c
6491 * added remote.sa-sparc.c, a modification of remote.c
6492 which conducts a dialog directly with the SparcStation prom.
6493 * breakpoint.c, infrun.c, sparcdep.c added
6494 remote_insert_breakpoint(), and remote_remove_breakpoint()
6495 to breakpoint.c instead of directly writing breakpoint instructions.
6496 * sparcdep.c on remote_debugging,there is no need
6497 to remove signle step breakpoint instructions.
6498 * main.c added "-epoch" flag and "int epoch_interface" to main.c
6500 * printcmd.c - epoch interface sends lisp expressions to open up
6501 epoch windows on inspection.
6502 * valprint.c - added arrayprint, and addressprint and made adding
6503 format controls easier
6504 * wait.h added a couple of undef's because we were getting
6505 complaints about WSTOPSIG and WTERMSIG begin redefined.

6575 * valprint.c (everywhere): TYPE_NAME (TYPE) no longer comes in the
6576 form "struct ..." for GNU C++. Don't flush any part of TYPE_NAME
6577 when printing the type.

6601 step_resume_break_address != NULL, even if another_trap.
6602 If trap_expected and we enter sigtramp, then set up a
