33 (complain, clear_complaints, syms_from_objfile): Fix complaint
35 * xcoffexec.c: Change syms_from_objfile caller.

41 Mon Dec 2 11:04:05 1991 Per Bothner (bothner at cygnus.com)
43 * mips-tdep.c (init_extra_frame_info): Float register
44 'i' has gdb-internal number 'FP0+i', not '32+i'.
45 * mipsread.c (new_symbol): Translate g++ special
46 symbol "$t" to "this".

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

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

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

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

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

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

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

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

289 TYPE_CPLUS_SPECIFIC unless TYPE is TYPE_CODE_STRUCT.
290 * buildsym.c (read_type): Allocate TYPE_CPLUS_SPECIFIC for
292 (read_struct_type): Ditto. Also, add comments about how we can
293 deduce TYPE_VPTR_FIELDNO from inheritance info and fieldname info.
294 * coffread.c (decode_base_type): Allocate TYPE_CPLUS_SPECIFIC for
296 (read_struct_type): Ditto.
297 * dwarfread.c (struct_type): Ditto.
299 * symtab.c (read_range_type): Don't set TYPE_MAIN_VARIANT.

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

350 Motorola 88000 port without tears, I mean without tdescs.
352 * m88k-tdep.c: Blow away all tdesc stuff.
353 Provide functions for all the frame-related macros in
354 tm-delta88.h. Adopt i960-style EXTRA_FRAME_INFO.

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

392 * symtab.c (decode_line_1): For example (see above), here.
393 * buildsym.c, symtab.h: Remove TYPE_FLAGS_HAS{CON,DE}STRUCTOR
394 flags since they are no longer used.
396 Fixes to support C++ methods with functional parameters.
397 * c-exp.y (func_mod rule): Allow (and ignore) list of parameter
398 types in a function type.
399 * eval.c (parse_and_eval_type), value.h: New function,
400 parse_and_eval_type, is based on old code from check_stub_method.
401 But don't actually evaluate the cast, since that calls
402 value_cast(), whcih may fail. Just extract the type
403 from the parsed expression.
404 * values.c (check_stub_method): While looping through the
405 arguments, adjust depth *after* parameter has been handled.
406 Replace call and setup of parse_and_eval with new function

454 This includes a "struct objfile" that owns symtabs and psymtabs
455 that were read in from that binary file.
457 * symfile.h: Add struct objfile. Add pointer to the objfile
458 into the struct sym_fns.
459 Replace global `symfile' and `symfile_mtime' with

508 * dwarfread.c (scan_compilation_units, start_psymtab,
509 process_dies, end_symtab, dwarf_build_psymtabs,
510 read_lexical_block_scope, read_func_scope, read_file_scope): Take
511 and use objfile argument.
512 (psymtab_to_symtab_1, read_ofile_symtab): Don't take or use file
513 descriptor. Use BFD internal functions instead.
514 (end_symtab): Call global allocate_symtab.
516 * elfread.c, target.c: Minor changes to accommodate objfiles.
517 * symtab.h: partial_symbol_table has no symfile_name member now.
518 (fn_fieldlists voffset): avoid non-int bitfield.
519 (struct symtab): Add objfile * and objfile_chain * of symtabs.
520 (struct partial_symtab): Add objfile * and objfile_chain * of
521 psymtabs. Remove symfile_name.
523 * symmisc.c: Lose free_all_symtabs, free_all_psymtabs.
524 (printsyms_command): Rename from print_symtabs. Add selective
525 listing if 2nd argument given. Print objfile info.
526 (printpsyms_command): Rename from print_partial_symtabs. Ditto all.
527 (printobjfiles_command): New; prints objfiles lists, and checks
528 for consistency of symtab, psymtab, and objfile lists.
530 * symfile.h, symfile.c, symtab.h: Lint
532 Fri Nov 8 23:38:48 1991 John Gilmore (gnu at cygnus.com)
534 * command.c: Include param.h.
535 * defs.h (warning_setup, warning): Declare.
536 * expprint.c (print_subexp, UNOP_MEMVAL case): Lint.
537 * inflow.c (new_tty): Use USE_O_NOCTTY #define.
538 * language.c, printcmd.c (print_scalar_formatted), signame.c,
541 Thu Nov 7 18:26:15 1991 Steve Chamberlain (sac at rtl.cygnus.com)
543 * Makefile.in: link with libiberty after libreadline, since
544 readline might want something in libiberty.
545 * m88k-xdep.c: Fixed the register offsets in the ptrace_user
546 struct for BCS 88k machines.
547 * xm-m88k.h: don't define USIZE if already defined.
548 * configure.in: Added delta88 target.
550 Thu Nov 7 04:51:19 1991 John Gilmore (gnu at cygnus.com)
552 * am29k-pinsn.c, am29k-opcode.h: Fix decoding of mtacc, dmac, fmac.
554 * tm-*.h: Remove READ_DBX_FORMAT, COFF_FORMAT, and
555 READ_MIPS_FORMAT, which have been unused since BFD. Still
556 remaining is COFF_NO_LONG_FILE_NAMES.
557 * tm-sun3.h, tm-altos.h: Remove detritus accidentally left from
558 function calling code moved to m68k-tdep.c.
560 Wed Nov 6 17:21:59 1991 John Gilmore (gnu at cygnus.com)
562 * coffread.c: Eliminate c_nsyms in favor of c_naux.
563 Complain if no auxents on .bf and .ef FCN symbols, and assume
564 lots of line numbers.
565 (init_linenos, enter_linenos): Use a sentinel at the end of the
566 read-in linenos, to make for a fast, safe loop-end test.
568 Wed Nov 6 02:54:08 1991 Steve Chamberlain (sac at cygnus.com)
570 * coffread.c (read_coff_symtab): coffread used to rely on the
571 x_sym.x_misc.x_lnsz.x_lnno field giving the # of linnos in a
572 function. Two of the formats I'm using (29k and 88k) don't seem to
573 set it. Ths patch to fcn_last_line and (enter_linenos) is an
574 attempt to use the actual size of the linno table in the file to set
575 the number of linenos to process.
577 Tue Nov 5 22:47:46 1991 Steve Chamberlain (sac at cygnus.com)
579 * Makefile.in: put a - infront of the mv y.tab.c c-exp.tab.c and
580 mv y.tab.c m2-exp.tab.c, so that if bison is used, and the files
581 are created in place, so the mv fails, then the make continues.
583 Tue Nov 5 16:47:47 1991 Per Bothner (bothner at cygnus.com)
585 Add C++ as a separate language.
586 * defs.h (enum language): Add language_cplus.
587 * dwarfread.c (end_symtab): Support language_cplus.
588 * c-exp.y: Add new struct language_defn cplus_language_defn.
589 Don't set c to be the default language (see main.c).
590 * c-exp.y (yylex): Only look for field of this if
591 language is C++. (First difference from C!)
592 * language.c: Add case branches for C++ (currently, all
593 the same as C). Also, add c++ to "usage" note for "set lang".
594 * valprint.c (typedef_print). Add case branches for C++.
595 * main.c (main): New way to set initial language: Look at
596 file extension of psymtab containing main(). (Same as we
597 do for symtabs, but avoid loading the symtab yet.)
598 * symtab.c: New routine find_main_psymtab(), used by main()
599 to set initial language.
600 * symfile.c (allocate_symtab): Move code for mapping file
601 extensions-> languages to new deduce_language_from_filename().
603 Fix a C++ problem when looking for methods in super-classes.
604 There was confusion between base and derived types.
605 * valops.c (value_fn_field): Change function interface.
606 * values.c: Use new value_fn_field interface.
608 Mon Nov 4 10:49:33 1991 Per Bothner (bothner at cygnus.com)
610 * infrun.c: Fixed typo in comment.
611 * utils.c: All the v*fprintf emulation is now in libiberty,
612 so we can get rid of some junk.
613 * xm-sun3os4.h, xm-sun4os4.h, xconfig/decstation, xconfig/i386sco,
614 xconfig/sun3os4, xconfig/sun4os4: Don`t need HAVE_STRSTR any more.
615 * m68k-pinsn.c (print_insn_arg): Support BB/BW/BL
616 type operands, as used by branch instructions.
617 * gmalloc.c: Fix prototype of memcpy.
618 * elfread.c: Comment out register_addr, since it conflicts
619 with the one in coredep.c.
620 * buildsym.h: Remove extern declarations of two functions
621 that are really static in buildsym.c.
622 * tm-mips.h: Add symbolic names for more registers.
623 * mips-xdep.c (store_inferior_registers): Use new register names.
624 * xm-mips.h: Simplify REGISTER_U_ADDR, since it is now
625 only used for core files, not ptrace. Therefore,
626 the KERNEL_U_ADDR hack is no longer needed.
627 The mapping to ptrace number is now in in mips-xdep.c.
628 * mips-xdep.c: Define REGISTER_PTRACE_ADDR (using the
629 mapping from the old REGISTER_U_ADDR), and use it
630 in {fetch,store}_inferior_registers.
631 * mipsread.c: Rename #include ecoff.h to new name coff-mips.h.
632 * mips-tdep.c (mips_push_dummy_frame, mips_pop_frame):
633 Save/restore FP regs correctly (?).
634 * dbxread.c: Remove duplicate define_symbol and type_synonym_name
635 (these had been previously moved to buildsym.c).
636 Hence, define_symbol becomes extern instead of static.
637 * buildsym.c (read_struct_type): Comment out bogus handling
638 of C++ operator methods. Minor hacking of reading of class
639 contexts. Make define_symbol non-static, so dbxread.c can call it.
641 Fri Nov 1 11:05:47 1991 John Gilmore (gnu at cygnus.com)
643 * mipsread.c (read_mips_symtab, read_the_mips_symtab): Use real
644 filename with error messages.
645 * stack.c (frame_select_command): Rename to select_frame_command
646 to avoid "fr" and "fra" having nonunique completions.
647 * symfile.c (sort_symtab_syms): Ignore sort of zero symtab *.
648 (symfile_init): Print file format name when unable to handle it.
649 (free_named_symtabs): Use BLOCKVECTOR rather than obsolete BLOCKLIST.
650 * symmisc.c (free_symtab): Only free linetable if nonzero.
651 * symtab.h: Remove obsolete BLOCKLIST macros.
653 Thu Oct 31 18:12:43 1991 Stu Grossman (grossman at cygnus.com)
655 * infrun.c (wait_for_inferior): another stepi/nexti fix. Ensure
656 that stop_step is 1 at bottom of main loop. I don't know why this
657 needs to be done, but it helps me sleep better at night.
659 Sun Oct 27 18:18:39 1991 Stu Grossman (grossman at cygnus.com)
661 * main.c (initialize_history): Read history after reading all
664 Sun Oct 27 14:09:25 1991 John Gilmore (gnu at cygnus.com)
666 * buildsym.c: Break out initial malloc sizes.
667 (record_line): Record directly in a subfile. Alloc on demand.
668 (compare_line_numbers): Add from xcoffread.c.
669 (end_symtab): New params say whether to sort pendings and
670 linetable. Patch block stabs if defined. Shrink linetable before
671 allocating the symtab.
672 * buildsym.h: Delete line_vector* and prev_line_number. Add
673 global_stabs and file_stabs for xcoffread.
674 * dbxread.c (start_subfile): Move to buildsym. Change above calls.
675 * symtab.h: LINETABLE(symtab) can now be null. Zap LINELIST.
676 * symmisc.c, symtab.c: Cope with null LINETABLEs.
678 * blockframe.c: Pass fromleaf to INIT_EXTRA_FRAME_INFO.
679 * tm-29k.h, tm-88k.h, tm-i960.h, tm-irix3.h, tm-mips.h, tm-pyr.h,
680 tm-sparc.h: Accept fromleaf parameter.
681 * c-exp.y (yyerror): Pass error message if given.
682 * configure.in: Add rs6000 host and target.
683 * inflow.c (new_tty): O_NOCTTY kludge for RS/6000.
684 * symfile.h (entry_point): Add.
686 Sat Oct 26 00:16:32 1991 John Gilmore (gnu at cygus.com)
688 * buildsym.c: New file. Breaks out symbol-table-building routines
689 from dbxread.c, so they can be shared with xcoffread.c.
690 * buildsym.h: New file. Declarations for buildsym.c users.
691 * dbxread.c: Remove large chunks into buildsym.c.
692 * Makefile.in: Add buildsym.c and buildsym.h.
694 * symfile.c (syms_from_bfd): New routine.
695 (add_symbol_file): Call it to do the real work.
696 (syms_from_bfd): Initialize entry_point before calling symfile_init.
697 * symtab.h, symfile.c, coffread.c, mipsread.c, dwarfread.c:
698 Avoid declaring or setting entry_point (symfile.h & symfile.c cope).
700 Fri Oct 25 10:58:16 1991 Mark Eichin (eichin at cygnus.com)
702 * cplus-dem.c (cplus-demangle): added support for templates, static
703 data, and the new (correct) mangling for destructors.
705 * dwarfread.c: (dwarfwarn): created a varargs version of
706 dwarfwarn, for non __STDC__ compilers.
708 * c-exp.y: (yylex): added match for "template" token.
709 (typebase): added TEMPLATE name '<' type '>' clause, for explicit
710 specification of template types.
712 * symtab.c: (lookup_template_type): new function for finding
713 templates in symbol table.
714 (type_name_no_tag): changed to explicitly check for s/u/e at the
715 beginning of the symbol - if it is a template, none of these will
716 be there (but the name will still contain spaces.)
718 Fri Oct 25 18:59:32 1991 Per Bothner (bothner at cygnus.com)
720 Various fixes to improve g++ debugging.
721 * symtab.h: Add is_const and is_volatile flags for each method.
722 These are bit fields - take their space from voffset,
723 which shrinks to 30 bits. Since voffset is now a bitfield,
724 make it unsigned for portability. This changes its interpretation
725 slightly: Static methods now have voffset 1 instead of -1,
726 and virtual offsets start at 2, not 1.
727 * symtab.c: Renamed gdb_mangle_typename to gdb_mangle_name,
728 since it now returns an entire magled method name, not just
729 the type part. This avoids some duplication.
730 It also allows us to correctly mangle const and volatile
731 methods (using the new is_const and is_volatile bit fields
733 * valprint.c (type_print_base), values.c (check_stub_method):
734 Simplify by using new gdb_mangle_name.
735 * values.c (value_headof): Fix to correctly handle single
736 inheritance (actually two fixes, either of which suffices).
737 * dbxread.c (read_struct_type): Handle const and volatile
739 * dbxread.c (read_struct_type): Yet one more place where
740 we must handle '\\' continuations.
741 * valprint.c (vtbl_ptr_name): Add final '\0'.
743 Fri Oct 25 16:06:38 1991 Stu Grossman (grossman at cygnus.com)
745 * tm-sparc.h, tm-68k.h (EXTRACT_RETURN_VALUE): fix output of
746 short return values for sparc and 68k. Patch from Paul Eggert.
748 * coffread.c, coredep.c, i386-xdep.c: install patches for
749 SysV/386 3.2 from Mauro DePalma.
751 Fri Oct 25 02:02:13 1991 John Gilmore (gnu at cygnus.com)
753 * core.c (core_file_info), exec.c (exec_file_info): Print file
754 type. Use printf_filtered.
756 * valops.c (value_fetch_lazy): Avoid 0-length fetches.
758 Thu Oct 24 23:06:40 1991 Fred Fish (fnf at cygnus.com)
760 * dwarfread.c: Add casts to remove compiler warnings.
762 * tm-3b1.h, tm-68k.h, tm-altos.h, tm-amix.h, tm-hp300bsd.h,
763 tm-hp300hpux.h, tm-isi.h, tm-news.h, tm-pn.h, tm-sun2.h,
764 tm-sun3.h: Remove locally duplicated code for calling functions
765 in the inferior. The only differences were in the specific trap
766 vectors used and whether or not an fpu was present. These are
767 now handled by appropriate definitions of BPT_VECTOR and
768 HAVE_68881 respectively. Other minor obvious cleanups.
770 * valops.c: Correct a minor misspelling.
772 * utils.c: Remove local BSD/USG hacks that are now in libiberty.
774 * dwarfread.c: Remove prototype for dwarfwarn. Does not work
777 Thu Oct 24 09:33:44 1991 John Gilmore (gnu at cygnus.com)
779 * stack.c (frame_command): Always print. Use new
780 frame_select_command to select a frame without printing.
782 * dwarfread.c: Use <varargs.h>, since <stdarg.h> is not portable.
784 Thu Oct 24 01:32:51 1991 Fred Fish (fnf at cygnus.com)
786 * dwarfread.c: New file for DWARF debugging format support.
788 * elfread.c: New file for ELF object file format support.
790 * procfs.c: New file for SVR4 /proc (process file system) support.
792 * tm-amix.h, xm-amix.h, tconfig/amix, xconfig/amix: New files for
795 * xm-svr4.h, tm-svr4.h: New files for SVR4 support.
797 * xm-m68k.h: New file for host machines with m68k cpu.
799 * Makefile.in: Add elfread.c and dwarfread.c to SFILES_MAINDIR.
800 Add elfread.o and dwarfread.o to OBS.
802 * symfile.h: Add "elf" to list of supported formats in comment.
804 * c-exp.y, defs.h, symtab.h, valprint.c: Add three new builtin
805 types to gdb, builtin_type_long_double, builtin_type_complex, and
806 builtin_type_double_complex. Add and use new TARGET_SHORT_BIT,
807 TARGET_INT_BIT, TARGET_LONG_BIT, TARGET_FLOAT_BIT,
808 TARGET_DOUBLE_BIT, TARGET_LONG_DOUBLE_BIT, TARGET_COMPLEX_BIT, and
809 TARGET_DOUBLE_COMPLEX_BIT, as the sizes in bits of the indicated
810 types on the target machine (ala the existing TARGET_LONG_LONG_BIT).
812 * infrun.c: When using SVR4 /proc interface instead of ptrace(),
813 call proc_set_exec_trap() to setup child to stop at first instruction.
815 * inftarg.c: When using SVR4 /proc interface, call proc_wait()
818 * m68k-tdep.c: Add new routines supply_gregset(), fill_gregset(),
819 supply_fpregset(), and fill_fpregset(), which are machine
820 dependent support routines for SVR4 /proc interface.
822 * utils.c: Add warning_setup() and warning(). Warning() behaves
823 the same as error() except that it returns normally rather than
824 jumping back to command level. Modules that don't want to call
825 warning() for some reason, but want to produce their own warnings,
826 can call warning_setup() to ensure compatibility with the way
827 warning() and error() deal with the terminal.
829 * symtab.c: Make internal errors produce more useful messages.
831 * tm-68k.h: Move code that is duplicated in almost every single
832 m68k based machine's configuration files to this common file.
833 Duplications in the configuration files still need to be removed
836 * infrun.c (child_create_inferior): System V versions must call
837 setpgrp() with no arguments, to comply with prototyping typically
840 * munch: Add support for SVR4 style nm output.
842 * dbxread.c, mipsread.c symmisc.c, symtab.c: Remove the object
843 file specific fields from the partial symbol table structure and
844 replace them with a pointer to private data for each different
845 flavor of object file reader to initialize appropriately.
847 Wed Oct 23 09:38:20 1991 John Gilmore (gnu at cygnus.com)
849 * xconfig/sun[34]os4: Add note about strstr botch on sunos4.0.3c
852 * mipsread.c (fixup_undef_type): New function. If a struct /
853 union / enum is defined in a header file but nowhere else used,
854 (by typedefing, pointer referencing or declaration) the mipsread code
855 builds the complete tree for the structure but leaves its code as
856 TYPE_CODE_UNDEF as it doesn't know what kind of aggregate it is.
857 Guess its type based on the details of the members.
859 Tue Oct 22 18:04:32 1991 Stu Grossman (grossman at cygnus.com)
861 * infrun.c (wait_for_inferior): Check return value from
864 Mon Oct 21 17:47:03 1991 Stu Grossman (grossman at cygnus.com)
866 * infrun.c (wait_for_inferior): fix stepi/nexti that was broken
867 by my last edit to this routine.
869 Mon Oct 21 14:27:43 1991 John Gilmore (gnu at cygnus.com)
871 * tm-sun3.h (FIX_CALL_DUMMY): problem with cross debugging.
872 FIX_CALL_DUMMY does unaligned accesses and/or forgets to byte swap
873 the values before putting them into the dummy code. (From Peter
876 Mon Oct 21 10:04:39 1991 Steve Chamberlain (steve at rtl.cygnus.com)
878 * configure.in: added ebmon target.
880 Wed Oct 16 22:49:58 1991 John Gilmore (gnu at cygnus.com)
884 * Makefile.in: Roll VERSION to 4.2.
885 * README, TODO, WHATS.NEW: Update.
887 * core.c (core_open): Improve error message for bad file.
888 Pass .reg virtual memory address to fetch_core_registers to help
889 it find the registers in the core-file header.
890 * coredep.c (fetch_core_registers): Take new argument, use it,
891 and pass it to register_addr to locate the block of registers.
892 * xm-mips.h: Update KERNEL_U_ADDR for new scheme. Cleanup a bit.
894 * dbxread.c (read_dbx_symtab, process_one_symbol): Handle
895 Sequent N_FN_SEQ like everybody else's N_FN.
897 * main.c: Circumvent SCO cc bug with #if !!defined(USG).
898 * tm-i386v.h: #endif guck.
899 * xconfig/i386*: Remove -Dgetpagesize()=4096 kludge.
900 * xconfig/i386sco: Add HAVE_STRSTR to avoid ANSI bdeath.
901 * xconfig/tahoe: Add REGEX, which seems to be missing.
903 * coredep.c: Add <sys/types.h> for SCOnix.
904 * dbxread.c (read_dbx_symntab): Avoid coredump on malformed file.
905 * printcmd.c (print_formatted): Flush output before disassembly.
907 Tue Oct 15 20:12:32 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
909 * doc/refcard.tex (sec "Working Files"): consistent metavars and
910 other improvements, due to comments by François Pinard
911 (pinard@iro.umontreal.ca)
913 * doc/gdb.texinfo (appendix "Installing GDB"): changes in
914 configure, and improvenets related to Pinard's refcard comments
916 Tue Oct 15 08:45:12 1991 John Gilmore (gnu at cygnus.com)
918 Changes from Fred Fish:
919 * tm-68k.h (FPI_REGNUM): Add.
920 * infrun.c (child_create_inferior): flush stdout and stderr
922 * configure.in: Handle amigados, amix hosts and targets.
923 * inflow.c: Handle TIOCGLTC_BROKEN for Amiga.
926 * values.c (show_convenience): Use printf_filtered.
927 * main.c (define_command): Check result of lookup_command for
929 (echo_command): Use printf_filtered, and force output out.
931 * dbxread.c (read_enum_type): Avoid Modula-2 kludge that breaks C
933 * i387-tdep.c (double_to_i387): Fix typo for double_to_ieee_extended.
934 * utils.c (_initialize_utils): If !ISATTY, don't paginate.
935 * configure.in, tconfig/decstation, xconfig/decstation: Rename
936 dec3100 to decstation.
938 Mon Oct 14 13:37:50 1991 Roland H. Pesch (pesch at cygnus.com)
940 * doc/gdb.texinfo: Catch up to changes recorded here in ChangeLog
941 (nodes Continuing and Stepping; Memory; Targets) clarifications
944 Fri Oct 11 23:27:06 1991 John Gilmore (gnu at cygnus.com)
946 * tm-{irix3,mips,nindy960,pn,symmetry,vx960}.h: Move
947 REGISTER_U_ADDR to corresponding xm- file. Sugg. by Peter Schauer.
949 * symmisc.c (print_partial_symtabs): Add printpsyms debug cmd.
951 * m68k-tdep.c (m68k_push_dummy_frame, m68k_pop_frame): Add
952 generic routines for calling inferior functions.
954 * blockframe.c (inside_main_scope, inside_entry_scope): New.
956 * copying.awk: Filter formfeeds out of copying & warrantee.
957 Make them available as `show copying' and `show warrantee' also.
958 * main.c (print_gnu_advertisement): Advt `show' commands.
960 Thu Oct 10 17:25:47 1991 John Gilmore (gnu at cygnus.com)
962 * mach386-xdep.c: Even when cross-compiling, leave in the
963 core-file reading code.
964 * core.c (get_core_registers): Avoid coredump if no .reg section.
966 Wed Oct 9 17:03:34 1991 John Gilmore (gnu at cygnus.com)
968 * mipsread.c, coffread.c: initialise TYPE_VPTR_FIELDNO to -1.
969 This avoids coredumps under `set print object on' in value_headof
970 (called erroneously by value_from_vtable_info) for `p &struct'
971 or `p *struct'. From Peter Schauer.
973 Mon Oct 7 00:06:52 1991 John Gilmore (gnu at cygnus.com)
975 * Makefile.in: Roll version to 4.1.2.
976 * dbxread.c: Use aout64.h, not a.out.gnu.h. Get external symbol entry
977 size from BFD (but, FIXME, we don't yet read external nlists's and
978 convert them to internal nlists's before handling them -- we still
979 assume they have the same size and alignment.) Use SET_NAMESTRING
981 * exec.c (exec_file_command): Move dead coff-encapsulation code
983 * m88k-tdep.c, m88k-xdep.c: Remove encap test and #inc <a.out.h>.
985 Fri Oct 4 22:30:06 1991 John Gilmore (gnu at cygnus.com)
987 * configure.in, tm-i386v.h, xm-i386v.h: Intel 386 Mach host port.
988 * xm-i386mach.h, mach386-xdep.c, xconfig/i386mach: New files.
990 Fri Oct 4 17:04:31 1991 Per Bothner (bothner at cygnus.com)
992 More patches from Peter Schauer <pes@regent.e-technik.tu-muenchen.de>:
993 * mips-xdep.c (store_inferior_registers): Don't try to
994 write the (pseudo) FP.
995 * mipsread.c (parse_partial_symbols): Improved algorithm for
996 setting pst->texthigh.
998 Fri Oct 4 16:47:32 1991 Roland H. Pesch (pesch at cygnus.com)
1000 * doc/Makefile: make TEXINPUTS include . everywhere
1002 Fri Oct 4 00:35:56 1991 John Gilmore (gnu at cygnus.com)
1004 * coffread.c, dbxread.c, symfile.c, symmisc.c, symtab.h: Remove
1005 vestiges of typevectors, which were for symsegs and are no longer
1006 used. (From a question by Eliot Dresselhaus
1007 <dresselh@RFT30.nas.nasa.gov>).
1009 Thu Oct 3 09:33:26 1991 John Gilmore (gnu at cygnus.com)
1011 * dbxread.c, coffread.c: static-ize functions that were
1012 gratuitiously external. (From Fred Fish.)
1014 * c-exp.y: sym->class to SYMBOL_CLASS (sym).
1016 * dbxread.c (dbx_lookup_type): Keep doubling size of typevector
1017 until it is large enough.
1019 * dbxread.c (read_type): Handle error case slightly better.
1020 Make complaint message not C++-specific.
1022 Wed Oct 2 17:21:07 1991 Stu Grossman (grossman at cygnus.com)
1024 * infrun.c (wait_for_inferior): Fix step/next so that you only
1025 stop at the beginning of a new line. This fixes various problems
1026 with for loops, nested if-else's and switch statements.
1028 Tue Oct 1 06:33:55 1991 John Gilmore (gnu at cygnus.com)
1030 * symtab.c (lookup_symtab_1, lookup_symbol): "fatal" errors
1031 between symtabs and psymtabs become ordinary error()s.
1033 * dbxread.c (read_dbx_symtab): Relocate end_of_text_addr
1034 properly, making "end pc" correct in shared lib psymtabs.
1035 (From Guy Harris <guy@auspex.com>.)
1037 Mon Sep 30 13:15:31 1991 John Gilmore (gnu at cygnus.com)
1039 * dbxread.c: Enable, but soften, const_vol_complaint.
1040 (read_dbx_symtab): N_STSYM and N_LCSYM define static vars.
1041 Ditto Gould N_NBSTS and N_NBLCS. Also, all types in the psymtab
1042 should be file-scope, not global.
1043 (read_struct_type): Remove ancient multiple-inheritance warning.
1044 (read_range_type): Check base type, complain & patch if undefined.
1045 * stack.c (frame_info): Demangle the function name in `info stack'.
1046 (From Peter Schauer)
1048 Sat Sep 28 10:02:33 1991 John Gilmore (gnu at cygnus.com)
1050 * eval.c (evaluate_subexp_for_address): Don't use
1051 TYPE_POINTER_TYPE directly (it might be zero if this type has
1052 never had a pointer created before); use lookup_pointer_type.
1053 * symtab.c (lookup_method_type): Arguments were swapped in all
1054 callers, so fix it here. I'm amazed this worked at all!
1056 Fri Sep 27 18:09:31 1991 John Gilmore (gnu at cygnus.com)
1058 * c-exp.y, m2-exp.y: Define more yysymbols that happen to be
1059 "bss" rather than "data" symbols, but which still conflict.
1062 * coffread.c (coff_symfile_read): Use xmalloc, not malloc.
1063 * core.c (core_files_info): Shorten output.
1064 * exec.c (exec_files_info): Ditto.
1065 (build_section_table): Ignore zero-length sections.
1066 * language.c, printcmd.c: Lint.
1067 * language.h (get_frame_language): Declare.
1068 * saber.suppress: update.
1069 * stack.c (find_relative_frame): Remove complex code that was
1070 #if 0'd, stick with simple code. Lint.
1071 * saber.suppress: Update a bit.
1072 * symfile.c (add_symbol_file_command): Add "?" to question.
1073 * utils.c (parse_escape): Avoid \a due to bdead compilers.
1074 * value.h: Declare typedef_print.
1076 * valprint.c (val_print, type_print_base): TYPE_CODE_RANGE less
1079 * nindy-tdep.c (nindy_frame_chain_valid): Use lookup_misc_func.
1080 (Reported by Mark Peek <mark@imagen.com>.)
1082 * solib.c (solib_map_sections): Relocate all sections, even
1083 though only the text section's size is tracked. Mark ld_text
1084 for eventual elimination as we generalize to N sections.
1086 * infrun.c (wait_for_inferior): Don't check if the PC is in a
1087 call_dummy if we were stopped by a random signal that is being
1088 passed to the program. This produced wierd results when calling
1089 functions in the inferior and signals (e.g. SIGALRM) were in use.
1091 Tue Sep 24 18:05:30 1991 John Gilmore (gnu at cygnus.com)
1093 * infrun.c (IN_SIGTRAMP): Not parenthesized properly.
1094 Bugfix from Paul Eggert <eggert@twinsun.com>.
1095 * tm-ultra3.h (IN_SIGTRAMP): Ditto.
1096 * valprint.c (print_floating): Print 9 digits for IEEE floats.

1109 * Makefile.in (VERSION): Set to 4.1.
1110 * language.c (set_language_command): Print useful help message,
1111 and restore the language string after giving help.
1112 * valprint.c (typedef_print): Print typedef in C or M2.
1113 * symtab.c (list_symbols): Use it.
1114 * main.c (main): Avoid any output before (gdb) prompt when -q.
1115 * language.c (set_language_command): Handle errors by restoring
1116 the language string to its current state (fix from A. Beers).
1117 * doc/gdbint.texinfo: Roll in information from README. Rearrange
1118 "how to install" and "how to print the doc" stuff so it drops
1120 * configure.in: Rename rtpc CPU to romp to match config.sub.
1121 * README, WHATS.NEW, TODO: Update for gdb-4.1.
1123 Fri Sep 20 17:39:14 1991 Roland H. Pesch (pesch at cygnus.com)
1125 * doc/gdb.texinfo: Updates from ChangeLog. set/show write,
1126 autoloading shared libs, copyright etc on GDB startup, clean up $_
1127 and $__ index refs, set/show listsize and related updates to list
1128 cmd. New host/target configs.
1130 Fri Sep 20 15:46:00 1991 Roland H. Pesch (pesch at cygnus.com)
1132 * doc/Makefile: generate aux version-no file doc/gdbVN.m4
1133 from main Makefile.in version definition
1134 doc/gdb.texinfo: use version recorded in doc/gdbVN.m4 for current
1136 Makefile.in (setup-to-dist): generate doc/gdbVN.m4
1138 * doc/gdb.texinfo: merge new language-switching and lang-specific
1141 Fri Sep 20 15:00:57 1991 Per Bothner (bothner at cygnus.com)
1143 * mcheck.c: Add __ONEFILE kludge to allow compilation by non-ANSI
1144 compilers (which may lack stddef.h).
1146 Fri Sep 20 13:29:42 1991 John Gilmore (gnu at cygnus.com)
1148 * dbxread.c (read_dbx_symtab, process_one_symbol): N_FN and
1149 N_WARNING are the same except for the N_EXT bit, so just use their
1150 values alone, rather than OR-ing them with N_EXT.
1152 Fri Sep 20 12:27:55 1991 Stu Grossman (grossman at cygnus.com)
1154 * mipsread.c (parse_lines): Deal with negative extended line
1157 * c-exp.y, m2-exp.y: #define yyerrflag and yynerrs to avoid
1158 global symbol conflicts.
1160 Fri Sep 20 02:28:15 1991 John Gilmore (gnu at cygnus.com)
1162 * .gdbinit: Move 'set complaints' to top, so it runs even in
1163 case we aren't debugging GDB.
1164 * language.c (_initialize_language): Fix type check and range
1165 check documentation strings.
1166 * utils.c (!HAVE_VPRINTF): Define vfprintf as a function, so
1167 language.c can use it. (Though language.c should really not be
1168 handling warnings/errors the way it does, FIXME.)
1169 * symtab.c (lookup_primitive_type): const lint.
1171 Bugfix from Peter Schauer:
1172 * source.c (lines_to_list): Make signed, to avoid comparison
1173 going unsigned and complaining that -3 is too high for 21 lines.
1174 * stack.c (lines_to_list): Ditto.
1176 Thu Sep 19 23:33:41 1991 John Gilmore (gnu at cygnus.com)
1178 * Makefile.in (HFILES): Add minimon.h.
1179 (VERSION): Roll version number to 4.0.95.
1180 (gdb.tar.Z, make-proto-gdb.dir, setup-to-dist, gdb-XXX.tar.Z):
1181 New rules for building distributions. Normal distribution
1182 is built by doing `make -f Makefile.in gdb.tar.Z' in the directory
1183 one level up from here; it calls make-proto-gdb.dir to build a
1184 directory `proto-gdb' which is an image of the release. The old
1185 `gdb.tar.Z' rule still works too.
1186 * config.sub, configure: Roll in latest from ..
1188 Thu Sep 19 17:41:24 1991 Roland H. Pesch (pesch at cygnus.com)
1190 * doc/gdbint.texinfo: Reorder contents; reorganize new-host,
1191 new-target, and new-config chapters; fix minor typos; come closer
1192 to usual GNU markup conventions for @file @samp @code @var.
1194 Thu Sep 19 17:04:12 1991 Per Bothner (bothner at cygnus.com)
1196 Patches from Peter Schauer <pes@regent.e-technik.tu-muenchen.de>:
1197 * mipsread.c (parse_partial_symbols): Enter the name of all
1198 structs/unions... into the psymtab so we can access them if the
1199 symtab is not read in.
1200 * mips-tdep.c: Remove some unneeded #includes.
1201 * xconfig/dec3100: Add HAVE_STRSTR.
1203 Thu Sep 19 15:14:23 1991 John Gilmore (gnu at cygnus.com)
1205 * Makefile.in: Circumvent Sun Make bug on *-exp.tab.o.
1206 * c-exp.y, m2-exp.y: Lint.
1207 * m2-exp.y: Avoid using yytname[] which is a Bison-ism.
1208 * valprint.c (val_print_fields): Check for stub type.
1209 * mipsread.c (_initialize_mipsread): Avoid using
1210 builtin_type_void at initialize time.
1211 (mipscoff_symfile_read): use it now.
1213 Wed Sep 18 15:55:51 1991 John Gilmore (gnu at cygnus.com)
1215 Merge multiple-language support, and partial Modula-2 support,
1216 from Andrew Beers <beers@cs.buffalo.edu>.
1218 * i387-tdep.c: New file, consolidates most 80387 support,
1219 and eliminates host dependency on double<->extended conversions.
1220 * i386-xdep.c, symm-xdep.c: Remove most 387 support.
1221 * xconfig/i386{sco,v,v-g,v32,v32-g}: Now need i387-tdep.o.
1223 * symfile.c (allocate_symtab): New fn, consolidates the work
1224 of allocating and initializing a new struct symtab. Set the
1225 language of the symtab based on its filename extension.
1226 * symfile.h: Declare it.
1227 * mipsread.c (new_symtab): Use it. Minor formatting changes.
1228 * dbxread.c (end_symtab): Use it.
1230 * mipsread.c (parse_symbol, case stParam and stProc): Add #if 0'd
1231 code for saving types of parameters with each function definition.

1235 (read_range_type): Rename MAX_OF_TYPE to MAX_OF_C_TYPE, etc.
1236 #if 0 out its uses, though, since they set a dead value.
1237 * coffread.c (end_symtab): Use allocate_symtab.
1238 (process_coff_symbol): #if 0'd for functions and params as above.
1239 (read_enum_type): Recognize Modula-2 BOOLEAN.
1240 * symtab.c (add_param_to_type): #if 0'd function to add a
1241 parameter type to a function type's field list.
1243 * defs.h (local_hex_format, local_hex_string, *_custom): Add.
1244 * i386-xdep.c, pyr-tdep.c, pyr-xdep.c, remote-vx.c, solib.c,
1245 source.c, symfile.c, dbxread.c, breakpoint.c, core.c, exec.c,
1246 i387-tdep.c, infcmd.c, mips-tdep.c, stack.c, printcmd.c: Output
1247 hex with local_hex_string for Modula-2 support.
1249 * breakpoint.c (breakpoint_cond_eval): Use new value_true to test
1250 breakpoint condition language-independently.
1252 * parse.c: New file with the common code remains of expread.y.
1253 * parser-defs.h: New file with common declarations from expread.y.
1254 * c-exp.y: New file with the C parser from expread.y, and other
1255 language-specific information.
1256 * m2-exp.y: New file with the Modula-2 parser and etc.
1257 * expread.y, expread.tab.c: Remove.
1258 * breakpoint.c, eval.c, printcmd.c, expression.h: Use
1259 parse_expression and parse_exp_1 rather than parse_c_expression
1262 * symtab.h (enum languages): Move to defs.h.
1263 (enum type_code): Add TYPE_CODE_CHAR and TYPE_CODE_BOOL.

1278 * expression.h (enum exp_opcode): Add Modula-2 specific opcodes.
1279 * expprint.c: Look up expression opcodes in language-specific

1312 Tue Sep 17 08:37:41 1991 John Gilmore (gnu at cygint.cygnus.com)
1314 Add Andrew Beers' changes for Modula-2 support. His ChangeLog
1315 entries are enclosed herein. Not all of these changes
1316 have been merged into the master GDB sources -- check the
1317 ChangeLog above here for the merge log.
1319 Mon Jun 3 17:05:45 EDT 1991
1321 m2-exp.y Created. Tested outside of GDB for a few days. Proper
1322 operators were added, C specific operators and tokens
1323 removed. yylex() revamped to some extent. Still things
1324 missing from the grammar, such as sets.
1325 Tested for two weeks in GDB v3.5.
1327 Tue Jun 11 17:23:48 EDT 1991
1329 m2-exp.y Added boolean constants TRUE and FALSE to the grammar
1330 so they are built-in. Sort of a hack.
1332 Fri Jun 14 12:53:51 EDT 1991
1334 m2-exp.y Added range checking for numeric constants. Any numeric
1335 constant is assumed to be of builtin type INTEGER unless:
1336 (1) it is octal or hexadecimal, in which case it is a
1337 CARDINAL; (2) it is too big to fit into an INTEGER, in
1338 which case it is a CARDINAL.
1339 eval.c Added simple range checking for +, -, and * on integers.
1340 Doesn't work very well for *, since 6 * 1,000,000,000 =
1341 1,705,032,704, which fails the simple test of result >=
1342 first_operand, no matter in what order the operands are.
1344 Tue Jun 18 14:11:30 EDT 1991
1346 Broke the parser into parts, one containing the C grammar and the other
1347 containing code to be shared by all of the grammars.
1349 The following files no longer exist:
1354 The following files were added:
1356 c-exp.y (The C grammar)
1357 m2-exp.y (The Modula-2 grammar)
1358 parser-code.c (Code that is shared by the above grammar)
1362 Makefile.dist Changed to reflect the above dependencies. NOTE: It is
1363 now necessary to use the Bison compiler compiler, since it
1364 will generate function/variable prefixes other than yy.
1366 Tue Jun 18 16:47:49 EDT 1991
1368 symtab.[ch] Added the external variable working_lang, than holds the
1369 value of the current working language.
1370 Added the ennumerated type language_mode, with the values
1371 language_auto and language_manual, the former meaning that
1372 GDB sets working_lang as needed, and the latter meaning
1373 that the value of working_lang is totally under user
1375 symtab.[ch] Added the Modula-2 pervasive types INTEGER, CARDINAL,
1376 REAL, BOOLEAN and CHAR. Also added the type codes
1377 TYPE_CODE_BOOL and TYPE_CODE_CHAR.
1378 utils.c Added set_language_command and show_language_command to
1379 implement the GDB support commands "set language" and
1381 expression.h A number of identifiers were added to the type exp_opcode
1382 to facilitate Modula-2 builtin functions, integer
1383 division, and array indexing.
1385 Wed Jun 19 13:25:58 EDT 1991
1387 language.h Added the macro STRICT_TYPE, which evaluates to non-zero
1388 if the language specified by working_lang requires the use
1389 of strict typing of expressions. Eventually, even this
1390 will be able to be changed by the user.
1391 Added the macro RANGE_CHECK, which evaluates to non-zero
1392 if the language specified by working_lang requires the
1393 checking of a value against the domain of its type.
1394 Eventually, even this will be able to be changed by the
1396 language.[ch] Predicates involving types (simple_type, ordered_type,
1397 same_type, integral_type, numeric_type, character_type,
1398 boolean_type, float_type) are added. These predicates are
1399 based on the current value of working_lang, and are handy
1402 Wed Jun 19 15:39:34 EDT 1991
1404 eval.c Added the function type_array_rank which computes the rank
1406 valarith.c Added the funtion value_bool, which when given a integer
1407 value.h value (ie. struct value *) as an argument, it returns a
1408 boolean value (ie. struct value *) true if that integer
1409 is non-zero, and a boolean value false otherwise.
1410 valprint.c Added cases for TYPE_CODE_BOOL, so Modula-2 BOOLEAN values
1411 will print out properly.
1413 Wed Jun 19 16:36:34 EDT 1991
1415 valops.c Added the function value_capitalize, which returns it
1416 value.h argument capitalized if its argument is a lowercase
1417 letter, or the argument unchanged if its argument is not a
1419 valarith.c Added the function range_check_p, which returns non-zero
1420 value.h if its value argument is between the integral bounds upper
1422 Added the function range_check_enum_p, which makes sure
1423 that its value argument is a valid member of the domain of
1425 Added the function range_check_range_p, which makes sure
1426 its value argument lies between the upper and lower bounds
1427 of its type argument, which must be a ranged type.
1428 Added the function check_array_index, which range and type
1429 checks an index of an array.
1430 Added the function value_multi_subscript, which computes
1431 array[idx1,idx2...idxN], given a value array and an array
1432 of values representing indicies.
1433 values.c Changed value_from_long to work with TYPE_CODE_CHAR and
1434 unpack_long to work with TYPE_CODE_BOOL and
1437 Wed Jun 19 18:04:08 EDT 1991
1439 symtab.c Stored pervasive types in a structure and make
1440 lookup_pervasive_type() a lookup function that was based
1441 on working_lang. If lookup_pervasive_type() returned
1442 non-zero, then that value was returned (a fix, since
1443 before it simply wouldn't return the pervasive type.)
1444 language.h Added the macro CAST_IS_CONVERSION, which evaluates to
1445 non-zero if the language specified by working_lang means
1446 "conversion" when it says "cast".
1447 valops.c Added the function value_real_cast(), which performs a
1448 value.h *cast*, not a *conversion*, which is what value_cast()
1449 does when it can. In particular,
1450 value_cast(<float_type>,4) = 4.0, while
1451 value_real_cast(<float_type>,4) = some mess.
1452 eval.c Modula-2 builtin functions implemented: ABS, CAP, CHR,
1453 parser-code.c FLOAT, HIGH, MAX, MIN, ODD, ORD, TRUNC, and VAL.
1454 expression.h Added macros MAX_OF_TYPE and MIN_OF_TYPE to work with MAX
1455 and MIN on integral types. *NOTE*: These are currently
1456 hardcoded to work only if there are 8 bits per storage
1458 eval.c Made logical functions call value_bool to return a
1459 properly typed boolean value, based on working_lang.
1461 Thu Jun 20 11:55:27 EDT 1991
1463 valprint.c Types now print out in a Modula-2 fashion. This works for
1464 the cases when the type is printed out step-by-step, that
1465 is, it doesn't work when the name of a structured type
1466 (which includes the keyword "struct", etc.) is simply
1468 FIXME: Perhaps this is bad. Parts of it seem to kludgey,
1469 since type specifications in C and Modula-2 are very
1470 different. The C printing of a type is very recursive,
1471 whereas in Modula-2 it is generally very simple. C has
1472 type prefixes and suffixes, which have no real analogue in
1473 Modula-2. Maybe type_print() should call a language
1474 specific type printer. This is also advantageous if we
1475 compile GDB to exclude some of the languages. We'll just
1476 leave those functions out.
1478 Thu Jun 20 16:57:10 EDT 1991
1480 dbxread.c When reading the complete symbol table in (via
1481 psymtab_to_symtab()), the number and types of function
1482 arguments are added to a function type. define_symbol()
1483 calls add_param_to_type() to accomplish this.
1484 Assumption: when we come across a function definition
1485 (N_FUN symbol with an 'f' or 'F' in the name), its
1486 arguments will appear before another function definition.
1487 When a function is found, a pointer to its type is placed
1488 in the global in_function_type. Changes that
1489 add_param_to_type() makes are to this global.
1490 valprint.c The type of a function now includes (for Modula-2) the
1491 types of its parameters.
1492 eval.c Type checking and a check for the proper number of
1493 arguments is now done for function calls. Not sure of the
1494 impact this has on C++ member function yet.
1496 Thu Jun 20 19:58:48 EDT 1991
1498 valprint.c Rewrote the type printer. Broke it into two language
1499 specific parts, adding the functions type_print_m2() and
1501 An unfortunate consequence is this: if you debugging a C
1502 program in Modula-2 mode (why?), info types does not work
1503 well with regular expressions, since the types are printed
1504 out in Modula-2 terminology, but stored in C terminology.
1505 language.[ch] Added the functions new_type_last(), type_keyword(), and
1506 type_sep() to aid in the printing of typedefs.
1507 symtab.c Made the printing of typedefs as language independent as
1508 possible through calls to new_type_last(), type_keyword(),
1511 Fri Jun 21 11:50:26 EDT 1991
1513 dbxread.c Check all incoming ennumerated types. If it looks like
1514 Modula-2's BOOLEAN type, then change the type_code of the
1515 type to TYPE_CODE_BOOL so we can process it as a boolean
1517 valprint.c Replaced some of the 0x%x with calls to sprintf and
1518 hexformat() in val_print().
1519 language.[ch] Added the function hex_to_string(), which converts its
1520 integral argument to a hexadecimal number (format is
1521 language based) and returns the result as a string.
1523 Mon Jun 24 12:25:07 EDT 1991
1525 valprint.c Some functions call type_print_1() directly, instead of
1526 value.h using type_print(), so they can specify where (column) to
1527 print things. Since type_print() takes care of language
1528 dependence, that needs to be called first. Added a
1529 parameter depth to type_print() (so it is now like
1530 type_print_1). Changed type_print to type_print_at, and
1531 made type_print a macro that passes a depth argument of
1533 symmisc.c Changed all calls to type_print_1 to calls to
1535 Makefile.dist Made it possible to build GDB for a specific set of
1536 depend languages. Do this by passing a definition for the macro
1537 LANGS to make. LANGS should be a string containing a
1538 space-separated list of language names (ie. LANGS="c m2").
1539 The default is to build all languages. Note that grammar
1540 files must follow the naming convention of <lang>-exp.y.
1541 gdb.lang This holds the current value of the LANGS macro. It is
1542 examined every time make is called, and is updated if
1544 eval.c Added #ifdef _LANG_<lang> to these files.
1545 expread.c Still need to add them to dbxread.c and coffread.c.
1553 Mon Jun 24 16:33:11 EDT 1991
1555 language.[ch] Added the functions hexformat_pre() and
1556 hex_to_string_pre(), which take a prefix argument to
1557 include in the format string. Thus, hexformat_pre("08") will
1558 return "0x08x" (if the working language is language_c).
1559 Made hexformat() and hex_to_string() calls to the above
1560 with "" as the prefix argument.
1562 am29k-pinsn.c, arm-pinsn.c, breakpoint.c, convex-tdep.c, exec.c, core.c,
1563 dbxread.c, i386-pinsn.c, i386-stub.c, i386-xdep.c, i960-pinsn.c,
1564 infcmd.c, inflow.c, m68k-pinsn.c, m68k-stub.c, m88k-pinsn.c,
1565 mips-pinsn.c, mips-tdep.c, ns32k-pinsn.c, printcmd.c, pyr-pinsn.c,
1566 pyr-tdep.c, pyr-xdep.c, remote-vx.c, remote.c, solib.c, source.c,
1567 stack.c, sun386-xdep.c, symfile.c, symm-xdep.c, symmisc.c, tahoe-pinsn.c,
1568 valprint.c, vax-pinsn.c
1570 Changed all occurences of 0x%[0-9]*l*x in printf format strings to
1571 calls to hexformat() and hex_to_string(). Format strings without
1572 the leading "0x" were ignored.
1574 depend Updated to take the above into account.
1577 Tue Jun 25 15:27:18 EDT 1991
1579 symtab.h Added the types range_mode_t, range_check_t, type_mode_t,
1580 and type_check_t to keep track of the current state of
1581 range and type checking.
1582 main.c Added the variables range_mode, range_check, type_mode,
1583 and type_check to record the current state of range and
1584 type checking. Added initialization code to main().
1585 language.h Changed the macros STRICT_TYPE and RANGE_CHECK to examine
1586 the above variables.
1589 Tue Jun 25 17:57:08 EDT 1991
1591 dbxread.c process_one_symbol() updates the variable (enum language)
1592 source_lang based on the extension of the filename
1593 contained in the N_SO sybmol that started this symtab.
1594 When end_symtab() is called, the value of source_lang is
1595 put into the language field.
1596 stack.c select_frame() sets working_lang (and possibly type_check
1597 and range_check) to the language field of the symtab
1598 associated with the frame that is selected if working_mode
1599 is language_auto. If working_mode is language_manual, a
1600 warning is printed and working_lang is not set.
1601 language.c Added the function set_type_range(), which sets the value of
1602 type_check and range_check (if their modes call for
1603 automatic setting) based on the current value of
1604 working_lang. A non-zero argument will cause the current
1605 settings to be output.
1608 Wed Jun 26 14:51:40 EDT 1991
1610 eval.c Added range checks on assignment.
1611 m2-exp.y Added the grammar for sets to the language. Currently,
1612 these do not do anything except print an error message.
1614 Wed Jun 26 17:01:04 EDT 1991
1616 m2-exp.y Added the ability for parse_number() to parse negative
1617 numbers. A global flag is set upon encountering a unary
1618 minus. This was done to make, for example, 1 parse as a
1619 CARDINAL, and not as an integer, per Wirth's examples in
1620 Programming in Modula-2 ed.4.
1621 valprint.c Added support for "set radix 2" by then setting
1622 output_format to 't'.
1623 eval.c Implemented range checking on subrange types. Added calls
1624 to range_check_range_p for BINOP_ASSIGN and BINOP_VAL.
1625 Implemented MIN and MAX for ennumerated types. The
1626 minimum value of an ennumerated type is defined by Wirth
1627 as the first identifier, and the maximum as the last.
1628 m2-exp.y Made octal numbers ending with "B" be characters and those
1629 ending with "C" be numbers, per Wirth's book. (p. 34)
1631 Thu Jun 27 14:11:52 EDT 1991
1633 stack.c select_frame() now only sets working_lang, it does not
1634 notify the user. If working_mode is language_manual, then
1635 a warning is issued once.
1636 main.c At the end of each call to execute_command(), working_lang
1637 is checked against the local static (enum language)
1638 current. If they differ and working_mode is
1639 language_auto, the new settings of language, type and
1640 range checking are printed out.
1641 stack.c Modified frame_info() to include the language of the
1642 current frame in the output of "info frame".
1643 language.[ch] Added the function language_str() which returns the name
1644 of the current language.
1646 Fri Jun 28 15:33:14 EDT 1991
1648 m2-exp.y Added the built-in procedures INC, INCL, DEC, and DECL to
1649 the language. INCL and DECL currently cause an error,
1650 since sets are not implemented yet. INC and DEC are
1651 implemented as PREINCREMENT/PREDECREMENT with one
1652 argument, and as ASSIGN_MODIFY with two arguments.
1653 eval.c Added type checking to the above cases.
1654 value.h Added not_lval_constant to the lval_type ennumerated type.
1655 not_lval_constant means that the value is a constant
1656 value; that is 3 or 'a' or TRUE, not as in a constant
1657 identifier. This is used to help coerce numbers such as 3
1658 to either signed or unsigned numbers.
1659 valops.c Added the function value_coerce_constants() which coerces
1660 constant integers as following: if one is a constant and
1661 the other is not, the constant's type is set to the type
1662 of the other argument. If both are constants and one is
1663 signed, the other is converted to a signed constant.
1665 Sat Jun 29 17:26:29 EDT 1991
1667 valarith.c Added a better range checker. It now checks range
1668 (successfully) on integral operations [+-] (signed and
1669 unsigned) for any C sized type. Still does not work well
1670 for multiplication.)
1671 int_in_size() returns an integer that is coerced to fit into
1672 specified number of bytes.
1674 Mon Jul 1 13:04:14 EDT 1991
1676 language.[ch] Added the function binop_result_type(), which returns the
1677 builtin (struct type *) type that would be the result of a
1678 binop on the two values V1 and V2.
1680 Wed Jul 3 19:22:53 EDT 1991
1682 source.c Extended source_info() to include the source language in
1683 the output from "info source".
1685 Fri Jul 5 13:48:52 EDT 1991
1687 utils.c Moved the support functions for the GDB set/show commands
1688 dealing with language into language.c.
1689 language.c Added the function language_info(), which displays info
1690 about the current working language, type and range check
1691 settings. Called via the GDB command "info language".
1692 Added an initialization routine _initialize_language(),
1693 that sets defaults for the language, type and range
1694 variables and sets up the new GDB commands.
1695 main.c Language setup moved to language.c.
1698 Mon Jul 8 10:10:22 EDT 1991
1700 valarith.c Debugged the range checker for arithmetic. Still does not
1701 work for multiplication very well.
1703 Mon Jul 8 12:40:37 EDT 1991
1705 language.[ch] Added the function value_true() which returns non-zero if
1706 its argument represents a boolean true value.
1707 breakpoint.c Changed breakpoint_cond_eval() to call value_true() to
1708 check the truth of an expression.
1710 Thu Jul 11 12:51:34 EDT 1991
1712 language.[ch] Added the predicate structured_type(), which returns
1713 non-zero if the argument is a structured type.
1714 Added the predicate pointer_type(), which returns non-zero
1715 if the argument is a pointer type.
1716 eval.c Added the ability to do addition and substraction on
1717 pointers and integers. This case simply bypasses the
1720 Thu Jul 11 14:41:42 EDT 1991
1723 Added the symbol N_DEFD (0x4a) which is a definition
1724 module dependency that is used by the GNU Modula-2
1725 compiler and the linker. It is not important to GDB,
1726 except that [dbx|coff|mips]read.c should ignore these
1729 Fri Jul 12 16:07:00 EDT 1991
1731 valprint.c Changed the TYPE_LENGTH(type) >= 0 to TYPE_LENGTH(type) >
1732 0 in val_print(). Also added statements to the else part
1733 to coerce type (argument to val_print) to a pointer type
1734 if it is an "array of unspecified length".
1735 valops.c Added the function value_m2_string(), which returns a
1736 (value) value which is a constant string, whose type is
1737 (ARRAY [0..n] OF CHAR). The length field of the type
1738 structure is set to zero, so it will be interpreted as an
1739 "array of unspecified length".
1740 stack.c Moved the language/frame mismatch check to
1741 main.c:execute_command().
1742 main.c The working language is recorded each time
1743 execute_command() is executed. If working lang has
1744 changed during its execution, then the new
1745 language/type/range info is printed out for the user. If
1746 the working language does not match the language of the
1747 frame, a warning is issued.
1749 Sat Jul 13 16:16:39 EDT 1991
1751 eval.c Moved all the type-checking stuff for operators to
1752 language.[ch] language.c. This is so we can keep language-specific
1753 stuff (like for what type operators are defined) in
1755 language.[ch] Added the function binop_type_check(), which checks to see
1756 if its two (value) arguments are type-compatible with its
1757 opcode argument. The opcode should represent an operation
1758 involving an operator. Also added the macro function
1759 unop_type_check, which calls binop_type_check with a
1760 NULL second argument.
1761 expprint.c Added Modula-2 operators to the op_print_tab, so info
1762 expression.h break works correctly. Also added "op_string", which
1763 returns the string corresponding to the (enum exp_opcode)
1764 opcode that is its argument.
1767 Sat Jul 13 18:26:18 EDT 1991
1769 coffread.c Added code to record the type of function arguments with
1770 each paricular function. Code is very similar to that
1772 dbxread.c Moved add_param_to_type() to symtab.c
1773 symtab.[ch] Added function add_param_to_type() from dbxread.c
1775 *** NOTE: The above additions have not been tested.
1777 Mon Jul 15 12:50:47 EDT 1991
1779 langauge.[ch] Added the functions type_error and range_error, which work
1780 like error() except if the type/range mode is set to
1781 *_mode_warn, then they do not do a return_to_top_level(),
1782 but merely print a warning.
1783 Also changed [set|show]_[type|range]_command() to support
1784 the new "warn" feature.
1786 Thu Jul 18 17:50:54 EDT 1991
1788 mipsread.c Added code to record the type of function arguments with
1789 each particular function. Code is very similar to that
1792 *** NOTE: The above additions have not been tested.
1794 Fri Jul 19 11:19:10 EDT 1991
1796 defs.h Added macros MAX_OF_SIZE, MIN_OF_SIZE, UMAX_OF_SIZE, and
1797 UMIN_OF_SIZE, which when given a size of a numeric type,
1798 return the maximum and minimum value it can hold. UMAX...
1799 and UMIN... return the result for unsigned types.
1800 symtab.h Added the macros MAX_OF_TYPE and MIN_OF_TYPE to operate on
1801 struct types. They call above macros.
1802 dbxread.c Renamed the MAX and MIN_OF_TYPE macros to ..._OF_CTYPE to
1803 avoid a name conlict with the above.
1804 c-exp.y Added range checking on numeric constants in
1805 parse_number() for completeness.
1806 valarith.c Made binop_user_defined_p() and unop_user_defined_p()
1807 return 0 if working_lang is not language_c.
1809 Thu Aug 8 14:17:22 EDT 1991
1813 breakpoint.c Documentation strings of some commands changed to
1814 eliminate the references to the C language where
1817 Tue Aug 13 15:48:03 EDT 1991
1819 m2-exp.y Added qualified identifiers to the grammar. The semantics
1820 are slightly different from those of the GDB operator ::
1822 m2-exp.y Added a rule to each grammar of the form: start ::= exp |
1823 type_exp, where type_exp is any valid type expression.
1825 eval.c Added the opcode OP_TYPE, and an error case in eval.c.
1826 printcmd.c Modified ptype_command() so it actually parses the input
1827 (necessary for type expressions with scope qualifiers).
1828 Added the function ptype_eval() which expects an
1829 expression composed of one OP_TYPE element.
1830 *.[ch] Replaced all occurences of parse_c_expression with
1832 *.[ch] Replaced all occurences of parse_c_1 with parse_exp_1
1834 [End of ChangeLog entries from Andrew Beers for Modula-2 support.]
1836 Mon Sep 16 17:19:46 1991 John Gilmore (gnu at cygnus.com)
1838 Small fixes from Peter Schauer:
1840 * infrun.c (child_attach): Lint.
1841 * solib.c (find_solib): Handle shared libs version 2.
1843 Small fixes from David Wood:
1845 * xm-ultra3.h (SYS_SIGLIST_MISSING): Typo.
1849 * remote-vx.c: Move <stdio.h> to top, for FILE. Fix from
1850 John S <basrai%kanga.dnet@c3po.sm-alc.af.mil>.
1852 * utils.c (wrap_here): Avoid wrap action of fputs_filtered if
1853 chars_per_line is at maximum (user typed `set width 0'). Fix
1854 from Andreas Schwab <schwab@ls5.informatik.uni-dortmund.de>.
1856 Tue Sep 17 17:31:04 1991 Stu Grossman (grossman at cygnus.com)
1858 * coredep.c: include ptrace.h where necessary.
1859 * mipsread.c(parse_lines): fix unsigned char problem that was
1860 messing up line numbers on SGI's and possibly other MIPS based
1862 * infrun.c (child_create_inferior): use better test to check
1863 return val from setpgrp().
1864 * tm-irix3.h, xm-irix3.h, tconfig/irix3, xconfig/irix3: add these
1865 for sgi/irix support.
1867 Wed Sep 18 04:33:31 1991 Per Bothner (bothner at cygnus.com)
1869 * mipsread.c (parse_symbol): Put non-static procedures
1870 in the global block.
1872 Fri Sep 13 00:14:52 1991 John Gilmore (gnu at cygnus.com)
1874 Patch together `text_start' and `text_end' for 29K port.
1876 * exec.c (exec_command): If NEED_TEXT_START_END, define the
1877 variables and set them based on the exec file.
1878 * am29k-tdep.c: declare text_start.
1879 * valops.c (call_function_by_hand): declare text_end.
1881 * inferior.h: Eliminate CANNOT_EXECUTE_STACK in favor of
1882 defining CALL_DUMMY_LOCATION as BEFORE_TEXT_END. This is
1883 because machines that do this will also have to know to
1884 set NEED_TEXT_START_END. Besides, it was a redundant way to
1886 * tm-29k.h, tm-convex.h, tm-np1.h: Eliminate
1887 CANNOT_EXECUTE_STACK, define CALL_DUMMY_LOCATION and
1888 NEED_TEXT_START_END.
1890 Thu Sep 12 00:22:24 1991 John Gilmore (gnu at cygint.cygnus.com)
1892 AMD 29000 changes from David Wood <wood@david.ultra.nyu.edu>:
1894 * Makefile.in (CLIBS): Put XM_CLIBS and TM_CLIBS at end.
1895 Pass MUNCH_DEFINE to munch whenever we run it.
1896 * am29k-pinsn.c (print_insn): Handle NOP specially. Avoid %#x
1897 format string; use 0x%x instead.
1898 * am29k-tdep.c: Use DUMMY_SAVE_GREGS and RETURN_REGNUM.
1899 * ultra-xdep.c, xm-ultra.h: New files for Ultracomputer host system.
1900 * xm-rtbsd.h: New host support for RT/PC running BSD Unix.
1901 * inflow.c: Handle `short' process group IDs.
1902 * infptrace.c (fetch_register): Support CANNOT_FETCH_REGISTER,
1903 and check for ptrace errors.
1904 * coffread.c (SDB_REG_TO_REGNUM): Define if not already.
1905 (coff_symfile_init): Initialize text_bfd_scnum.
1906 (read_coff_symtab): Use it to find the text [and absolute?] sections.
1907 * ../config.sub: Add vendor nyu and os "sym[1-9]*".
1908 * configure.in: Add hosts rtpc-*-* and a29k-*-*.
1909 Merge target arm case with other "easy" cases. Add target
1910 cases a29k-*-none (rehack of am29k), a29k-*-kern (remote to
1911 Ultracomputer kernel), and a29k-*-sym1 (ultracomputer OS's user
1913 * minimon.h, remote-adapt.c, remote-mm.c: Add.
1914 * munch: Cope with RT/PC putting fns in data segment.
1915 Restore ability to override `nm' by specifying MUNCH_NM.
1916 * xconfig/rtbsd, xconfig/ultra3: New host systems.
1917 * tconfig/a29k: Rename from tconfig/am29k. Add remote-mm
1918 and remote-adapt. Remove encapsulated coff #define's (the
1919 support should go in BFD, and gdb shouldn't know or care).
1920 * tconfig/a29k-kern: Same, but for remote kernel debugging.
1921 * tconfig/ultra3: For debugging user processes on Ultra3/Sym1.
1922 * tm-29k.h: Update BADMAG (though it should go away).
1923 Allow the register definitions to be overridden in another
1924 tm-file. Fix SR_REGNUM. Add a mess of _REGNUM's. Separate
1925 RETURN_REGNUM from GR96_REGNUM and DUMMY_SAVE_GREGS from
1926 DUMMY_SAVE_GR96, for handling kernel calling conventions
1927 that use GR64+ rather than GR96+.
1928 * tm-ultra3.h: New file, for use on Ultra3 Unix as well as for
1929 remote debugging of Ultra3 kernel. Includes tm-29k.h and
1930 overrides various things.
1932 * remote-mm.c (mm_attach, mm_wait): Handle attach like
1933 child_attach does, making a clean stop in the newly attached
1935 * remote-eb.c: Lint.
1937 * coffread.c: Make coffread independent of any particular
1938 variant of COFF. Avoid #include-ing any particular one except
1939 internalcoff.h. BFD now passes key values for symbol reading
1940 as part of its coff_data structure (LINESZ, SYMESZ, AUXESZ,
1941 and the symbol masks and shifts); use them.
1942 Remove obsolete end_of_text_addr.
1944 * exec.c: Remove unused include files.
1946 Wed Sep 11 19:38:44 1991 John Gilmore (gnu at cygint.cygnus.com)
1948 * Makefile.in (documentation targets): Pass $(M4).
1949 Bugfix from eggert@twinsun.com (Paul Eggert).
1951 * stack.c (down_silently_command): Check for stack existence.
1953 Tue Sep 10 23:08:29 1991 John Gilmore (gnu at cygint.cygnus.com)
1955 * Makefile.in (VERSION): Update to 4.0.3.
1957 Tue Sep 10 09:19:29 1991 John Gilmore (gnu at cygint.cygnus.com)
1959 * core.c (core_file_command): Print frame at coredump with
1960 its level number, by calling print_stack_frame.
1961 * frame.h: Add selected_frame_level, print_stack_frame.
1962 * frame.h, stack.c: Remove print_sel_frame, print_selected_frame.
1963 * convex-tdep.c, convex-xdep.c, infcmd.c, inflow.c, infrun.c:
1964 Change print_sel_frame and print_selected_frame callers to
1967 * dbxread.c (read_ofile_symtab): Avoid empty else clause.
1968 * symfile.c (free_named_symtabs): Ditto.
1969 * main.c (main): wrap_here needs an arg.
1970 * solib.c (find_solib): Avoid memory access if _DYNAMIC is zero.
1971 (solib_add): Avoid noise.
1972 (solib_create_inferior_hook): Lint.
1973 (sharedlibrary_command): Move dont_repeat to here.
1974 * utils.c (error): Call wrap_here to force buffered output.
1976 Small patches from Peter Schauer:
1978 * coffread.c (start_symtab): Free any existing line_vector before
1980 (read_coff_symtab): Ditto for type_vector.
1982 * source.c (lines_to_list): New variable, replacing function.
1983 (all uses): Use as variable.
1984 (_initialize_source): Add 'set listsize' and 'show listsize'.
1985 * utils.c (lines_to_list): Remove function.
1986 * stack.c (print_frame_info): Use as variable.
1987 * defs.h (lines_to_list): Remove declaration.
1989 Mon Sep 9 13:45:57 1991 John Gilmore (gnu at cygint.cygnus.com)
1991 * breakpoint.c (insert_breakpoints): Restore warning about
1992 the program might be running in another process, but only for
1993 systems with this brain death (#ifdef ONE_PROCESS_WRITETEXT).
1994 * xm-hp300bsd.h, xm-mips.h, xm-vax.h: Define it.
1996 * utils.c (error): if error_pre_print is set, print the string
1998 * main.c (main, print_gnu_advertisement, print_gdb_version):
1999 Reformat legalese so it always prints, but acts as an "I'm here"
2000 message while symbols are being read. If any errors occur,
2001 print a few newlines to set off the message and start it at the
2002 left margin. Remove mention of "help" command, and don't yak
2003 about symbol reading.
2004 (catch_errors): Error string is now printed first in case of
2006 * command.c (undef_cmd_error, lookup_cmd): On undefined command,
2007 suggest the "help" command.
2009 * Makefile.in (VERSION): Set to 4.0.2.
2011 Thu Sep 5 23:49:48 1991 John Gilmore (gnu at cygint.cygnus.com)
2013 * .gdbinit: Remove useless "rr" command. Set complaints
2014 to 1 for people debugging gdb.
2016 * breakpoint.c, remote-vx.c: Reword strings printed by
2017 catch_errors callers.
2019 Wed Sep 4 11:07:50 1991 John Gilmore (gnu at cygint.cygnus.com)
2021 * WHATS.NEW: "history write -> history save". Doc "write on/off".
2022 (Fix from kenc@viewlogic.com.)
2024 Fix some infrastructure to be able to cope with host and target
2025 machines with different sized basic types (ints, ptrs, etc).
2026 (Idea from pierre@la.tce.com (Pierre Willard).)
2028 * values.c (value_from_longest): Rename from value_from_long.
2029 Handle pointer types as well as integers, so that targets with
2030 different pointer sizes from the host can be accomodated.
2031 * breakpoint.c, convex-tdep.c, eval.c, expprint.c, printcmd.c,
2032 valarith.c, valops.c, valprint.c, value.h, values.c: Rename
2033 uses of value_from_long to value_from_longest.
2034 * eval.c, findvar.c, printcmd.c, valarith.c, valops.c: Pass
2035 the correct pointer type to value_from_long{est}.
2037 * doc/gdb.texinfo ($_, $__): Describe types of these variables.
2039 * remote-vx.c: Remove obsolete code for calling functions via
2040 vxworks kludge interface (it referenced value_from_long).
2042 * valops.c (value_string): Find malloc with lookup_misc_func, not
2045 Tue Sep 3 18:37:46 1991 John Gilmore (gnu at cygint.cygnus.com)
2047 Make writing to files work properly. (Fixes to BFD are also needed.)
2049 * core.c (core_open): Open file ourselves, read or r/w, depending on
2050 write_files. Use bfd_fdopenr.
2051 * gdbcore.h (write_files): New variable.
2052 * exec.c (write_files): Define variable, add set&show for it.
2053 (exec_file_command): Use write_files to open for read or r/write.
2055 Make shared library reading happen automatically. These changes
2056 are mostly from Peter Schauer <pes@regent.e-technik.tu-muenchen.de>.
2058 * inferior.h (stop_soon_quietly): Add to exported variables.
2059 * infrun.c (child_create_inferior): call solib hook, if defined.
2060 (child_attach): call solib hook, if defined.
2061 * solib.c: Include inferior.h. Add from_tty to so_list as kludge.
2062 (find_solib): Use lookup_misc_func rather than hand-rolled.
2063 (symbol_add_stub): New stub for catch_errors.
2064 (solib_add): Avoid output if !from_tty. Catch errors rather
2065 than just calling symbol_file_add and bombing.
2066 (solib_create_inferior_hook): Interface with the target process
2067 to let it read and alloc shared libs, then figure out what it did.
2069 * core.c (validate_files): Fix typo, soften warning.
2070 (Fix from Hiroto Kagotani <kagotani@cs.titech.ac.jp>.)
2072 * utils.c (fputs_demangled): Avoid duplicate printing if
2073 demangling is off. (Fix from J.T. Conklin <jtc@cayenne.com>.)
2075 * infrun.c (proceed): Cast -1 to (CORE_ADDR) before comparing.
2076 (Fix from pierre@la.tce.com (Pierre Willard).)
2078 * main.c (catch_errors): Change argument to a char * from an int,
2079 since a char * can point to a struct full of glop, but an int
2080 is not guaranteed to be able to hold a pointer.
2081 * breakpoint.c (breakpoint_cond_eval, bpstat_stop_status,
2082 breakpoint_re_set_one, breakpoint_re_set): Adapt.
2083 * core.c (core_open, solib_add_stub): Adapt.
2084 * remote-vx.c (symbol_stub, add_symbol_stub, callers): Adapt.
2086 Wed Aug 28 18:18:05 1991 John Gilmore (gnu at cygint.cygnus.com)
2088 * Makefile.in: Update VERSION to 4.0.1. Evade GNU Make bug
2089 by adding .NOEXPORT target.
2091 Fri Aug 23 17:14:25 1991 John Gilmore (gnu at cygint.cygnus.com)
2095 * Makefile.in (VERSION): Roll to 4.0.
2096 (gdb.tar.Z): Make refcard.ps as well, for shipment.
2098 Fri Aug 23 14:07:09 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
2100 * doc/gdb.texinfo: minor rewordings, crossref to ptype from print,
2103 * doc/Makefile, Makefile.in: generate "gdb-all.texi" rather than
2106 * doc/rdl-apps.texi: renamed from rdl-apps.texinfo
2108 * Makefile.in, doc/Makefile, doc/.Sanitize, doc/gdb.texinfo:
2109 reflect above name change
2111 * WHATS.NEW: correct pointer to refcard.
2113 * doc/gdb.texinfo: update New Features, Installing
2115 * doc/gdbint.texinfo: add short description of configure +template
2117 Fri Aug 23 11:46:08 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
2119 * doc/gdb.texinfo: update, fix bugs in "Installing" appendix
2121 Fri Aug 23 01:02:00 1991 John Gilmore (gnu at cygint.cygnus.com)
2123 * Makefile.in: Add config.sub, make doc/rdl-apps.texinfo for
2124 tar file, add dependencies for referenced doc files.
2126 Thu Aug 22 22:17:06 1991 Stu Grossman (grossman at cygint.cygnus.com)
2128 * coffread.c, symfile.c, stack.c: saberized.
2130 Thu Aug 22 16:20:27 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
2132 * doc/refcard.tex: permuted Essential Commands sec
2134 * doc/gdb.texinfo: new C++ chapter; revised installation appendix;
2136 set/show symbol-reloading
2137 default set complaints 0
2139 RET-repeat disabled after prompted long displays
2140 processID (attach) interpretation of 2nd GDB cmdline arg
2142 Thu Aug 22 14:05:47 1991 Stu Grossman (grossman at cygint.cygnus.com)
2144 * expread.y, coffread.c, dbxread.c, target.c, mem-break.c,
2145 cplus-dem.c, values.c, valprint.c, symfile.c, remote.c,
2146 breakpoint.c, main.c: lint.
2148 Thu Aug 22 02:02:26 1991 John Gilmore (gnu at cygint.cygnus.com)
2150 Install new configuration scheme for GDB and friends.
2152 * config.sub: Translate ordinary names to three-part names.
2153 * configure: Use three-part names internally.
2154 * configure.in: Translate three-part names to filenames.
2156 * README, WHATS.NEW: Update for gdb-4.0.
2157 * Makefile.in: Roll VERSION to 3.99.
2159 Wed Aug 21 18:21:09 1991 John Gilmore (gnu at cygint.cygnus.com)
2161 * infptrace.c (KERNEL_U_ADDR_BSD): Include a.out.gnu.h.
2162 * i960-tdep.c, m68k-tdep.c, sparc-tdep.c, tm-i960.h,
2163 tm-m68k.h, remote-nindy.c: Change ext_format_XXX structs
2164 to single structures rather than arrays; when passing
2165 their address, use &. This avoids trouble with bdead compilers.
2166 * mcheck.c: Don't include <stdlib.h>; just declare "void abort();"
2167 instead. This avoids portability headaches.
2168 * mips-tdep.c (mips_do_registers_info): Only print FP regs if
2170 * source.c (open_source_file): Avoid ANSI const bdeath by
2171 skipping declaration and then casting result value.
2172 * tm-hp300bsd.h: Clarify comment.
2173 * utils.c (strstr): Result is const char *; ANSI bdeath.
2174 * xm-hp300bsd.h: Define HOST_BYTE_ORDER. Redefine INT_MIN,
2175 since system include file defines it differently from "defs.h",
2176 though the two are equivalent for our purposes.
2177 * tconfig/hp300bsd: Add m68k-tdep.o.
2179 Tue Aug 20 16:01:11 1991 John Gilmore (gnu at cygint.cygnus.com)
2181 * tconfig/sun*4: Remove warnings about system assembler.
2183 Mon Aug 19 13:44:46 1991 John Gilmore (gnu at cygint.cygnus.com)
2185 * mcheck.c: Avoid warning about undeclared abort fn.
2186 * tm-sparc.h (PC_ADJUST): Avoid calling error() from this;
2187 it causes recursive calls to error() when used in cleanups.
2188 To do so requires that we make it a function, so we do.
2189 * sparc-tdep.c (sparc_pc_adjust): New implem of PC_ADJUST.
2190 * utils.c (do_cleanups): Remove the current cleanup from the
2191 chain *before* calling it, in case error() is called from it.
2192 The result won't be pretty, but won't be an infinite loop either.
2194 Mon Aug 19 00:41:04 1991 Michael Tiemann (tiemann at cygint.cygnus.com)
2196 * dbxread.c (read_struct_type): Grok anon structs for C++.
2197 (vb_name, vptr_name): Null terminate these strings.
2199 Fri Aug 16 08:31:03 1991 John Gilmore (gnu at cygint.cygnus.com)
2201 Minor bug fixes from BSD Net2 gdb:
2203 * blockframe.c (get_prev_frame_info): If FRAME_CHAIN_COMBINE
2204 returns 0, there is no previous frame.
2205 * breakpoint.c (commands_command): If !from_tty, don't call
2206 input_from_terminal_p().
2207 * dbxread.c (record_misc_function): Speed up slightly.
2208 (compare_psymbols): Ditto.
2209 * infcmd.c (do_registers_info): Take a second argument to
2210 determine whether to print float registers. "info registers"
2211 does not do so anymore. "info all-registers" does, now.
2212 * mips-tdep.c, pyr-tdep.c (xxx_do_registers_info): Take second
2214 * tm-mips.h, tm-pyr.h (DO_REGISTERS_INFO): Pass second arg.
2215 * inflow.c (initialize_inflow): Set tflags_ours correctly.
2219 * breakpoint.c (bpstat_do_actions): Use a cleanup to restore
2220 executing_breakpoint_commands if we are interrupted by error.
2221 * coffread.c (init_lineno): Avoid problem with zero-sized linetab
2222 versus malloc/free. From: john@labtam.labtam.oz.au (John Carey).
2223 * core.c (solib_add_stub, core_open): Call SOLIB_ADD inside a
2224 catch_errors() so we can setup the frame regardless of whether
2225 the shared libs work.
2226 * ieee-float.c (double_to_ieee_extended): Get exponent from
2227 right place in little-endian systems. From John Carey.
2229 Thu Aug 15 18:43:57 1991 John Gilmore (gnu at cygint.cygnus.com)
2231 * main.c: Remove unused terminating_signals and catch_termination().
2232 (long_options): Terminate with a zero element.
2233 [Bugfix from Atsuo Kawaguchi <atsuo@hark86.harl.hitachi.co.jp>.]
2234 (gdb_readline): Make call-compatible with readline.
2235 (init_signals): Improve comments re vfork vs. signal.
2237 * utils.c (prompt_for_continue): Use new gdb_readline().
2238 If we prompt for continuation, we don't let CR repeat the previous
2239 command, once we get back to a prompt. It's too easy to keep
2240 hitting CR, expecting "--more--" prompts, and have some long
2241 command start repeating on you.
2243 Tue Aug 13 16:17:56 1991 John Gilmore (gnu at cygint.cygnus.com)
2245 * blockframe.c (frameless_look_for_prologue): Speed up by
2246 calling SKIP_PROLOGUE_FRAMELESS_P if it's defined.
2247 * tm-sparc.h (SKIP_PROLOGUE, SKIP_PROLOGUE_FRAMELESS_P):
2248 Define two variants, one faster.
2249 * sparc-tdep.c (sparc_frame_chain): Use target_read_memory
2250 and return zero, rather than giving an error.
2251 (setup_arbitrary_frame): Initialize the PC in the new frame.
2252 (skip_prologue): Add a second arg saying whether we're just
2253 checking for a frameless function or not.
2255 * core.c (core_open, core_close, core_xfer_memory): Move
2256 section table pointers and bfd* into the target_ops.
2257 (core_open): Allow errors in shared lib reading, etc.
2258 (core_files_info): Describe shared library sections.
2260 * exec.c (exec_open, exec_close, exec_xfer_memory, xfer_memory,
2261 exec_files_info, set_section_command): Move section table
2262 pointers and bfd* into the target_ops.
2263 (add_to_section_table): Add BFD to section table.
2265 * target.c (target_xfer_memory, target_info): Pass target to
2266 xfer_memory and target_info functions.
2269 * gdbcore.h: Move struct section_table.
2270 * target.h: New home of struct section_table.
2272 * solib.c (solib_add): New argument is the target_ops whose
2273 section list is to be added to, if any. Reallocate the
2274 sections in that target to add any that come from shared libs.
2275 (throughout) so_sections renamed to sections.
2276 (solib_xfer_memory): Deleted.
2277 * tm-sunos.h (SOLIB_ADD): Add target argument.
2278 (SOLIB_XFER_MEMORY): Delete.
2280 * core.c, exec.c, inftarg.c, remote-eb.c, remote-nindy.c,
2281 remote-vx.c, remote.c, target.c, target.h: Remove add_syms vector
2282 from target_ops. It's the same on all targets. Add two section
2283 pointers to target_ops.
2285 * stack.c (find_relative_frame): Dump ancient algorithm for
2286 "down", just use handy "next" pointers.
2287 (frame_command): Don't error if there is no stack; let user
2290 * inflow.c (new_tty_prefork, new_tty): New prefork routine
2291 modifies static state in the parent process; new_tty itself
2292 runs in the child and modifies the child's file descriptors
2293 to match the saved static state.
2294 * infrun.c (child_create_inferior): Call new_tty_prefork,
2297 * infptrace.c (child_xfer_memory): Add ignored target arg.
2298 * remote-eb.c (eb_xfer_inferior_memory): ''
2299 * remote-nindy.c (nindy_xfer_inferior_memory): ''
2300 * remote-vx.c (vx_xfer_memory): ''
2301 * remote.c (remote_xfer_memory): ''. Rename from
2302 remote_xfer_inferior_memory.
2304 * main.c (main): Only try to attach "corefile" argument if
2305 it starts with a digit.
2307 * symfile.c (symbol_reloading): New "set/show" variable.
2308 (symbol_file_add): Shorten message about symbol reading.
2309 (add_symbol_file_command): Merge with add_syms_addr_command,
2310 since this should work on all targets now.
2311 (stop_whining): Default to zero, to shut up complaints
2312 about bad symbol tables on many systems.
2313 (free_named_symtabs): Just exit unless symbol_reloading.
2315 * xm-sun3os4.h, xm-sun4os4.h: Define BROKEN_LARGE_ALLOCA,
2316 and add comment explaining shared library screw.
2318 * source.c: #if defined => #ifdef.
2320 Thu Aug 8 12:23:19 1991 John Gilmore (gnu at cygint.cygnus.com)
2322 * doc/gdbint.texinfo: Improve doc on porting to new OS's.
2324 Tue Aug 6 17:16:15 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
2326 * doc/rdl-apps.texinfo: provide default readline-appendix finder
2327 (doc/Makefile knows how to make one for local config)
2329 * Makefile.in: use doc/Makefile for doc targets
2331 * doc/Makefile: GDB documentation now has its own Makefile
2332 doc/refcard.tex: renamed from "gdbrc.tex"
2333 doc/.Sanitize: add Makefile; recognize renamed refcard.tex
2334 doc/gdbint.texinfo: add markup in "Cleanups" chapter
2337 Fri Aug 2 00:13:06 1991 John Gilmore (gnu at cygint.cygnus.com)
2339 * values.c (baseclass_addr): When reading target memory, use the
2340 length of the basetype, not the upper type. We've only malloc'd
2341 enough space for the basetype, leading to errors in free().
2343 * expprint.c (print_subexp): Print UNOP_MEMVAL of an OP_LONG that
2344 ends up as a function specially, since we know the actual type of
2345 the pointed-to address. This (somewhat) fixes display of
2346 expressions that include misc_function_vector names. Try `cond 1
2347 !strcmp("a","b")' then `i b'.
2349 * infrun.c: Move DO_DEFERRED_STORES from proceed() to resume().
2350 The child can be proceeded from inside wait_for_inferior in
2351 evaluating breakpoint conditions, and DO_DEFERRED_STORES was
2352 getting skipped in that case.
2354 * expprint.c (print_subexp): Use filtered output, since the
2355 subroutines we call use it, otherwise the output is horribly
2356 mangled, since output of wrappable stuff comes out late.
2358 * Makefile.in: Bump VERSION to 3.98.1
2360 * infrun.c (child_create_process): Use execlp to find the
2361 shell to exec our target program. This requires some fiddling
2362 with `environ' since there is no execlpe().
2364 Thu Aug 1 15:35:17 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
2366 * Makefile.in, doc/gdbrc.tex, doc/rc-* (new files):
2367 Minor rearrangement of refcard permits two new make targets--
2368 gdbrc.dvi DVI output for refcard, using CM fonts
2369 gdbrc.ps PostScript refcard, using PS fonts
2371 Wed Jul 31 16:46:21 1991 John Gilmore (gnu at cygint.cygnus.com)
2375 * TODO, Projects, WHATS.NEW, README: Update for gdb-3.98.
2376 * Makefile.in (gdb-all.texinfo): Avoid touching file if M4 dies.
2378 Wed Jul 31 16:35:58 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
2380 * doc/gdb.texinfo: last changes for release.
2381 Minor typo and formatting fixes; incorporated most fixes remaining from
2382 filed mail commenting on earlier drafts.
2384 Added warnings: pipes don't work in run command;
2385 conditions are converse of assertions;
2386 step over fn without debug info goes to next fn;
2387 vars may have "wrong" values near fn entrance, exit
2389 Added example from Kingston on printing repeated nonadjacent values
2391 Added explicit mention that in Emacs gdb mode C-c and C-z are like
2392 shell mode for signals
2394 Renamed "Stepping and Continuing" to "Continuing and Stepping" so it
2395 doesn't sound so much like its parent "Stopping and Continuing"; also
2396 moved entries on continue to top of section, so they don't get lost.
2398 Improved installation directions in appendix, added manual formatting
2401 Tue Jul 30 17:26:39 1991 John Gilmore (gnu at cygint.cygnus.com)
2403 * configure.in: Remove xm.h and tm.h even if we aren't linking
2404 new ones, so "./configure sun4; ./configure none" does the right
2405 thing. Assume that alldeps.mak and depend are already built in
2406 srcdir, and avoid running "make" (particularly "make depend",
2407 which involves "gcc") from inside configure. Build Makefile
2408 directly rather than building Makefile.conf first.
2409 * configure: Regenerate with above changes.
2410 * Makefile.in: Use $(BISON) to find bison. Roll VERSION
2411 to 3.98. Revise gdb.tar.Z procedure to produce a file
2412 called gdb-$(VERSION).tar.Z but which unpacks into a
2413 directory called "gdb". Move non-source files out of
2414 $(SFILES_SUBDIR). Pretty up alldeps.mak with comments.
2415 (depend): Don't try to do "gcc expread.y".
2416 (expread.o): Update dependencies by hand.
2418 Mon Jul 29 15:21:09 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
2421 Fixed a variety of small typos that prevented info from formatting
2422 cleanly; altered too-long heading for GPL Appendix, as discussed
2423 w/RMS; Changed date on cover to July 91.
2425 Fri Jul 26 13:20:02 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
2428 (1) Applied some fixes due to comments from Larry Breed (easier ones
2429 through chapsec 5.2)
2430 (2) Eliminated use of @footnote---had my doubts about it anyways, and
2431 it's broken in latest texinfo
2432 (3) Introduced *some* use of [] for optional arguments, where
2433 explanation is not simpler by listing cmd w arg and cmd w/out arg
2434 separately. Still not using @deffn.
2435 (4) Dropped in GPL-2. NOTE: one of GPL-2 or texinfo is broken; a
2436 couple of headings are too long. Need patches to texinfo or revision
2439 * Partial update to README (which still needs work for this
2440 release!): (1) use of configure corrected for new script,
2441 (2) "make gdb.dvi" and "make gdb.info" mentioned.
2443 Wed Jul 24 06:44:02 1991 John Gilmore (gnu at cygint.cygnus.com)
2445 * symtab.c (lookup_symbol): Don't complain right off about
2446 no debug symbols; use the misc function vector first.
2447 (list_symbols): Use misc function vector to find symbols
2448 that don't have debug info, and print them.
2449 (find_pc_symtab): Temporarily avoid fatal() when psymtab
2450 PC range doesn't match symtab PC range, as it does on the
2451 MIPS because our symtab reading isn't perfect.
2453 * dbxread.c (dbx_symfile_read): Make warning about
2454 "no debug symbols" slightly nicer.
2456 * source.c (select_source_symtab): If "main" symbol exists,
2457 but decode_line_spec can't find line info, don't just return
2458 a zero; try other source symtabs or give an error.
2460 * mipsread.c (parse_partial_symbols): Sort the psymtabs by
2461 their low addresses first, then rip through fixing high addrs.
2463 * ns32k-opcode.h (sfsr): Bugfix from Rune Nerg}rd,
2464 <runene@ifi.uio.no>.
2465 (NS32K_SVC_IMMED_OPERANDS): Reverse the #ifndef.
2467 Tue Jul 23 18:52:43 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
2469 * Minor, mostly mechanical, cleanup of doc subdir for clean
2470 makeinfo'ing and TeXing; also ensured gdb-all.texinfo (post-m4)
2471 and gdb.info (post- texinfo2 makeinfo) generated for distribution.
2473 Sun Jul 21 03:54:52 1991 John Gilmore (gnu at cygint.cygnus.com)
2475 Mostly MIPS and general symbol-reading fixups.
2477 * doc/gdbint.texinfo: Add documentation on symbol-reading
2480 * mipsread.c: Remove kludges around #include "ecoff.h".
2481 Remove redefinitions of a_magic, etc, no longer used.
2482 (parse_symbol, ): Convert "Internal:" printfs to complain()ts.
2483 Fix global overview comments to match symfile.c protocol.
2484 (mipscoff_new_init): Eliminate cur_hdr if we have one.
2485 (mipscoff_symfile_read): Eliminate unused code. Avoid
2486 sorting all the symtabs, when all we have read here is psymtabs.
2487 The symtabs are sorted as they are created anyway. Tell
2488 condense_misc_bunches whether we're mainline.
2489 (psymtab_to_symtab_1): Pass filename when recursing, to make
2490 stack trace more informative.
2491 (parse_partial_symbols): Assume cur_hdr as argument.
2492 (read_mips_symtab): Don't clobber cur_hdr, so it can be freed.
2493 Pass cur_hdr implicitly to parse_partial_symbols. Avoid checking
2494 the TYPE_NAME of char *, since that's done in symfile.c.
2495 (free_numargs, parse_symbol, add_symbol, add_block,
2496 shrink_linetable): Declare these fns void.
2497 (upgrade_type): Convert tree of if's to switch. Clean up
2498 bogus "off == 0" handling with a complaint. Avoid setting
2499 field bitpos and bitsize of array with lower and upper bounds.
2500 Check specified bitsize of elements against their actual type's
2501 bitsize, and complain if different. Complain about unknown
2503 (parse_fdr): Don't assume sizeof(char *) == sizeof (struct *).
2504 (psymtab_to_symtab_1): Print names of subsidiary files that
2505 are being read in. FIXME, we read far too many files. This code
2506 is not the problem, the problem is in parse_fdr where the psymtabs
2508 (cross_ref): Result should indicate that we used one aux entry
2509 normally, or two if we encountered a "next" entry. This used
2510 to leave the caller pointing at the wrong aux entry.
2511 (add_symbol): If overflowed cur_block, reallocate it larger,
2512 chase all pointers to it, and complain(), rather than clobber memory.
2513 (shrink_block): Use xrealloc rather than xmalloc-and-copy.
2514 (new_field): Only allocate one field initially, not two.
2515 Pull ++ out of macro argument. Simplify.
2516 (_initialize_mipsread): Avoid initialization of importd
2517 global_psymbols and static_psymbols.
2519 * symfile.c (psymtab_to_symtab): Depend on XXX_psymtab_to_symtab
2520 to properly set pst->symtab; avoid searching for it.
2521 (symfile_fns): Improve comments, add a FIXME.
2522 * dbxread.c: Update comments to reflect symfile protocol.
2523 (read_ofile_symtab, end_symtab): Return the symtab.
2524 (psymtab_to_symtab_1): Set pst->symtab.
2526 * coffread.c (coff_symfile_read): tell condense_misc_bunches
2527 whether we're mainline.
2529 * symfile.h (sym_fns): Remove unused sym_discard member.
2530 * coffread.c, mipsread.c, dbxread.c: Remove XXX_symfile_discard.
2532 * mtrace.c (mtrace): Take effect if mallwatch is set, even if
2533 the environment variable is not.
2534 * infcmd.c (finish_command): Use filtered printfs.
2535 * cplus-dem.c: Add struct tags to a few unnamed structs.
2536 * valops.c (value_coerce_array): Improve comments.
2537 * valprint.c (type_print_varspec_suffix): Print array size only
2538 if greater than zero.
2539 * m88k-tdep.c: Shift some lines left by one space, that had
2540 apparently been trashed at some point.
2541 * TODO: More things to do, a few got done.
2543 Thu Jul 18 22:46:05 1991 John Gilmore (gnu at cygint.cygnus.com)
2545 * symtab.h (LOC_EXTERNAL): Eliminate in favor of LOC_STATIC.
2546 (ldsymoff, ldsymlen, globals_offset, statics_offset): Improve
2548 * dbxread.c (read_dbx_symtab): LOC_EXTERNAL -> LOC_STATIC.
2549 * expread.y, findvar.c, symmisc.c: Ditto.
2550 * printcmd.c (address_info): Update printed forms of LOC_
2551 symbols. Elim LOC_EXTERNAL.
2552 (print_frame_args): Keep track of param stack offsets before
2553 re-looking up to find the local register param is kept in.
2555 * mipsread.c: Use <symconst.h> and <sym.h> rather than <syms.h>.
2556 Further integration of mipsread into gdb. Eliminate unused
2557 routines, duplicate declarations. Handle static symbols in
2558 psymtabs as well as external symbols. When reading symtabs,
2559 insert symbols into the correct block (global, static, or a local
2561 (read_mips_symtab, parse_partial_symbols): Don't pass useless
2563 (mipscoff_symfile_read): Don't call select_source_symtab.
2564 (parse_symbol): Use SYMBOL_VALUE_ADDRESS where appropriate,
2565 rather than SYMBOL_VALUE.
2566 (parse_external): Comment clobbering of top_stack.
2567 (parse_partial_symbols): Update comments. Allocate and parse
2568 static symbols as well as external symbols. FIXME, enum values
2569 are not handled in this pass, but should be. Inline new_psymbol.
2570 Use SYMBOL_VALUE_ADDRESS.
2571 (psymtab_to_symtab_1): Read symbols into global static block
2572 by default (until enter some function's local block context).
2573 (sort_blocks): Clean up STATIC_BLOCK as well as GLOBAL_BLOCK.
2574 (destroy_all_symtabs, new_psymbol): Eliminate, unused.
2576 * source.c (select_source_symtab): Select a source symtab
2577 from either the symtabs or, failing that, the psymtabs.
2578 (list_command): Update error message.
2579 (forward_search_command, reverse_search_command): Use getc, not
2580 fgetc, for speed. FIXME, add comment about buffers that die if
2581 overrun by long line.
2583 * values.c (unpack_field_as_long, modify_field): Avoid shifting
2584 by an entire word, which is not portable, if we have a 32-bit
2585 field. (Code in dbxread.c already turns such bitfields, if
2586 aligned, into ordinary ints, but fixing this will help for other
2587 symbol formats and for future changes.)
2588 * core.c (core_open): Handle ANSI const brain death.
2589 * utils.c (vprintf): Fix varargs typo.
2591 Sun Jul 14 00:42:53 1991 John Gilmore (gnu at cygint.cygnus.com)
2593 * findvar.c (find_var_value): Handle &function better.
2594 * TODO: Document work needed on &fn and &array.
2595 * printcmd.c (print_address_symbolic): New arg is the prefix
2596 to print if a name is printed.
2597 (print_address_demangle): Honor "set print address" now.
2598 Use new arg above to improve spacing of output.
2599 * valprint.c (val_print): When printing function pointers,
2600 print symbolic form too.
2601 * breakpoint.c (breakpoint_1): Use new print_address_symbolic.
2603 Mon Jul 8 19:02:46 1991 John Gilmore (gnu at cygint.cygnus.com)
2605 * core.c (memory_error): Reword error msg to mislead less.
2607 * mips-pinsn.c (print_insn_arg 'd'): Print $ with reg name.
2609 * mipsread.c (read_mips_symtab, read_the_mips_symtab,
2610 parse_partial_symbols): Use newer BFD internals (external_filehdr
2611 and external_aouthdr), byte-swap the fields that we care about
2612 before using them, and make the file header data local to
2613 read_the_mips_symtab rather than global.
2615 Sat Jul 6 01:34:15 1991 John Gilmore (gnu at cygint.cygnus.com)
2617 * ns32k-opcode.h (movmw, movmd): Fix opcodes. Bug fix
2618 from Rune Nerg}rd <runene@ifi.uio.no> on 5 Jul 1991.
2620 * main.c (command_line_input): Flush stdout and stderr
2621 before every call to readline. This reportedly fixes a bug
2622 that comes up in Sys V running emacs-gdb and/or xxgdb,
2623 when stdin/out are pipes or sockets.
2625 Thu Jul 4 14:47:06 1991 John Gilmore (gnu at cygint.cygnus.com)
2627 * configure.in, Makefile.in: Avoid rebuilding "depend" as much.
2628 Avoid declaring Makefile dependencies, because GNU Make stupidly
2629 tries to update it if we do.
2631 * coffread.c: Revise for minor changes to bfd internal coff
2634 * configure: If -template= is given a relative path, make it
2635 absolute before recurring in subdirectories.
2637 * configure, configure.in, Makefile.in: Install "configure" script
2638 as replacement for config.gdb.
2639 * config.gdb, Makefile.dist, Makefile.sdir: Remove
2640 * README: Update for configure, mostly. FIXME.
2642 * Add dec3100 as equivalent to littlemips. Indicate in all host &
2643 target config files that they are for the host. When the lines
2644 get copied into the Makefile, this makes it more obvious what's
2647 Mon Jun 24 23:49:07 1991 John Gilmore (gnu at cygint.cygnus.com)
2649 * sparc-opcode.h (trap opcodes): Avoid leading spaces or
2650 tabs, which end up in the disassembler output inadvertently.
2652 Wed May 29 23:01:03 1991 John Gilmore (gnu at cygint.cygnus.com)
2654 Make it compile cleanly in an ANSI GCC2 environment.
2656 * blockframe.c: <stdio.h>
2657 * cplus-dem.c: free takes a void *, ifdef __STDC__
2658 * dbxread.c (read_huge_number): avoid gcc2 bug hoisting calc of
2660 * defs.h (alloca): Avoid doing anything if alloca already def'd.
2661 * stddef.h, stdlib.h: Remove these files.
2662 * symtab.c: Avoid declaring qsort, close.
2663 * symfile.c: Avoid declaring close.
2664 * utils.c (vprintf): Declare "ap" arg as proper va_alist.
2665 * sparc-tdep.c: Avoid including lots of Sun-host-specific files.
2667 Assorted other changes.
2668 * dbxread.c: include "libaout.h", not "liba.out.h".
2669 * printcmd.c (print_frame_args): Set recurse properly for
2670 indentation of struct and array parameters.
2671 * valops.c (value_cast): Allow cast to void.
2672 * infrun.c (resume): If NO_SINGLE_STEP, call machine dependent
2673 single_step() in a target-independent fashion.
2674 * sparc-tdep.c (single_step): Don't call ptrace ourselves, just
2675 set up to be ready to continue. This makes us target independent.
2676 * infptrace.c (child_resume): Remove call to single_step; now
2677 can single step a SPARC target of any kind.
2679 Wed May 22 18:18:24 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
2681 * Makefile.dist, doc/gdb.texinfo, doc/*-m4.texinfo: split up GDB
2682 docn into separate sections---basically chapters, plus two loose
2683 pieces that can be configured to go in different places. This
2684 allows GNU m4 to preprocess the manual without coredumping.
2686 * Makefile.dist: tell TeX where to find texinfo.
2688 Mon May 20 12:15:04 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
2690 * Makefile.dist, doc/gdb.texinfo: respectively create, and use,
2691 the new target "rdl-apps.texinfo" which captures the Makefile
2692 variable that records where to find the Readline libraries.
2694 Sun May 19 05:36:59 1991 John Gilmore (gnu at cygint.cygnus.com)
2696 * tahoe-pinsn.c: #include "tahoe-opcode.h", not "opcode.h".
2697 * tm-tahoe.h (FIX_CALL_DUMMY): Ignore more parameters.
2698 * defs.h (const, volatile): Only define if not already defined.
2699 * Makefile.dist (gdb.tar.Z): Create doc subdir w/out CVS/RCS crud.
2701 * README: Update for release 3.95.
2702 * config.gdb: Don't create readline dir in subdir builds.
2703 * main.c: Include with "..." form for non-system include files,
2704 so "gcc -MM" for "make depend" works.
2705 Include readline files with "...h" rather than <readline/...h>.
2706 * mipsread.c: Include "ecoff.h" rather than "intel-coff.h".
2708 * coffread.c: Undo minor damage done by Rich Pixley. Use
2709 different internal and external representations of COFF
2710 data structures. Use new BFD routines for swapping them in and
2712 * symfile.c (free_named_symtabs): Avoid freeing file names that
2713 are null or empty. Old i960 tools seem to produce files that
2714 claim to have empty names, causing each successive file read
2715 to blow away the previous one.
2716 * sparc-xdep.c (deferred_stores): Repair minor damage by Rich.
2717 Move deferred_stores to top of file, but don't separate its
2718 #define's from its variable. Add commentary.
2719 * Makefile.dist: Fix Rich damage; undo "configure" changes in
2720 favor of keeping the (working) config.gdb. Move readline
2723 Fri May 17 12:49:56 1991 Per Bothner (via gnu at cygint.cygnus.com)
2725 * dbxread.c (read_struct_type): Try to handle g++ version 1 MI
2727 * infptrace.c (fetch_registers): no result, since now void.
2728 * tconfig/news: target depends on m68k-tdep too.
2730 Fri May 17 14:40:14 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
2732 * Makefile.dist: added readline/inc-*.texinfo to dependencies for
2735 * readline/inc-history.texinfo, readline/inc-readline.texinfo:
2736 applied various small fixes due to or inspired by RMS comments
2738 * doc/gdb.texinfo: finished using all RMS comments, save those for
2739 appendices on readline and cmd history (which are in other source
2742 Thu May 16 18:06:05 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
2744 * doc/gdb.texinfo: (1) Updated w/ref to RMS comments through
2745 chapter 9; (2) documented 'break' command's menu mode for
2746 overloaded names, in response to hgs problem report C++ p-31
2748 Wed May 15 11:02:48 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
2750 * doc/gdb.texinfo: (1) better introductory example; (2) more
2751 consistent use of @code, @samp, @file, @kbd throughout; small
2752 cleanups to first three nodes; (3) new "Contributors" node;
2753 (4) Appendix, Renamed Commands; (5) divert specialized startup
2754 instructions to "Targets" chapter for generic manuals, while
2755 leaving them up front for manuals specific to specialized
2756 environments; (6) apply fixes from RMS comments through chapter 4.
2758 * pretex.m4: modify explanatory text slightly (and redefine
2759 "regexp") to keep GNU m4 from complaining. (It still crashes
2760 later, but one step at a time...)
2762 Wed May 15 10:32:12 1991 John Gilmore (gnu at cygint.cygnus.com)
2764 * readline/readline.c (update_line): Avoid dereferencing a pointer
2765 before comparing it to its bounds. Saber caught this.
2766 (init_terminal_io): Don't set BC from the "pc=" termcap variable,
2767 and only set PC if tgetstr returned non-null. Saber caught this.
2769 Tue May 14 16:29:53 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)
2771 * Makefile.dist: put gdb.dvi stuff (updated to use M4 preprocessor
2772 stuff for config manual) here where it counts; updated
2773 to use new subdir structure (gdb/doc/).
2775 * Makefile: generated from above via
2779 * gdbint.texinfo: added instructions on generating gdb.info* files
2780 locally for release. These are ordinary info
2781 files, formatted from gdb.texinfo (via gdb-all.texinfo, see
2782 Makefile)---but due to use of texinfo 2, can't count on makeinfo
2783 to generate these, so we distribute them already formatted.
2785 * gdb.texinfo: included full Info node and menu crud (as generated
2786 by C-u M-x texinfo-master-menu using the texinfo-2 elisp code).
2788 * Makefile: updated "gdb.dvi" target to use M4 preprocessor;
2789 put in comments-for-future gdb.info target (one day makeinfo will
2792 Tue May 14 13:51:36 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)
2794 * gdb.texinfo: Updated to include new or old undocumented
2795 commands, at least the following (perhaps some others I forgot to
2796 record): info f, info float, info path, info program, info s, info
2797 set, info source, info terminal, info types, info user, set/show
2799 Also covered all recent GDB command renames for v4.
2801 Mon May 13 14:57:46 1991 John Gilmore (gnu at cygint.cygnus.com)
2803 * mipsread.c: Rather than keeping count of how many symtabs
2804 and psymtabs we have, for sorting purposes, count them when
2805 we need to sort. This fixes bug in rereading of symbol tables.
2807 Fri May 10 15:43:33 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)
2809 * infcmd.c: renamed "info path" to "show paths"
2810 * gdbrc.tex: documented above.
2812 Wed May 8 04:51:11 1991 John Gilmore (gnu at cygint.cygnus.com)
2814 * remote.c: Fix comments.
2815 * utils.c (error): Force out any pending wrap output.
2817 Sat May 4 11:11:07 1991 John Gilmore (gnu at cygint.cygnus.com)
2819 * Makefile.dist: Roll VERSION to 3.95.
2820 Fix up "saber_gdb" to work again.
2821 * saber.suppress: Update.
2823 * coffread.c, exec.c, infptrace.c, inftarg.c, remote.c, solib.c,
2824 symtab.h, target.c, target.h: Lint.
2825 * core.c: setup and select frame after reading shared libs,
2826 else reading shared libs will clobber them. Lint.
2827 * utils.c (error): Force out any buffered wrap text.
2829 Fri May 3 22:01:56 1991 John Gilmore (gnu at cygint.cygnus.com)
2831 * remote.c: Remove decls of memory_insert_breakpoint
2832 and memory_remove_breakpoint, no longer used. (Suggestion of
2835 * Makefile.dist: use ${subdir} in paths of BFD and LIBIBERTY,
2836 to make it easier to interface to "configure"'d libraries.
2838 Fri May 3 13:10:01 PDT 1991 Roland Pesch (pesch at fowanton.cygnus.com)
2840 * valprint.c: introduce "set p", "set pr", "show p" and "show pr" as
2841 aliases for set/show print.
2843 Thu May 2 11:22:02 1991 Jim Kingdon (kingdon at cygint.cygnus.com)

2869 {unpack_,value_as_}long (for now anyway).
2871 * m88k-tdep.c (get_saved_register): Make get_reg a dc_word_t (*)().
2872 (psr_register): Change return type to dc_word_t.
2874 * m88k-tdep.c (tdesc_read_function): Comment out call to ptrace.
2876 * m88k-tdep.c (get_saved_register): Add lvalp parameter.
2878 * gdbcore.h (write_memory): Don't prototype it.
2880 * tm-88k.h, m88k-tdep.c: Make stack_error, stack_jmp global.
2881 m88k-xdep.c: Don't mention stack_error.
2883 * {x,t}config/m88k ({X,T}DEPFILES): Add missing files.
2885 * mtrace.c: Don't typedef things like size_t, just #define them.
2887 * coffread.c [TDESC]: #if 0 out references to coffsyn.
2889 * symtab.h (struct symtab): Include EXTRA_SYMTAB_INFO.
2890 tm-88k.h: Define EXTRA_SYMTAB_INFO.
2892 * coffread.c [TDESC]: Include "tdesc.h" and make tdesc_handle
2893 dc_dcontext_t not int.
2895 * coffread.c [TDESC]: Use system include files not <intel-coff.h>.
2897 * coffread.c [TDESC]: Move setting of debug_info from
2898 coff_symfile_read to find_linenos and make it work with BFD.
2900 * cplus-dem.c [__STDC__]: Make x{m,re}alloc return void*.
2902 * signame.c: Cast const char* to char* when assigning to sys_siglist.
2904 * utils.c (strsave): Make arg const char* not char*.
2906 * infrun.c (wait_for_inferior) [SHIFT_INSN_REGS]: Use
2907 bpstat_explains_signal (stop_bpstat) not stop_breakpoint.
2909 * tm-88k.h (START_INFERIOR_HOOK): Make tdesc_handle a dc_handle_t.

3382 * dbxread.c (end_symtab, end_psymtab): Change comments.
3383 (initialize_dbxread): Call dbx_new_init() in case the first
3384 command is add-symbols.
3385 * target.c (dummy_target): Permit add_syms_addr_command.
3387 Sat Apr 13 14:46:07 1991 John Gilmore (gnu at cygint.cygnus.com)
3389 Permit symbols to be superseded when new symbol files have
3390 been read in, particularly for VxWorks.
3392 * dbxread.c (read_dbx_symtab): Allow N_SOL to cleanly take us back
3393 to the main file, as well as to include files. Also, put global
3394 functions into the global psymtab, to make "i fun" work.
3395 (end_psymtab): Free named symtabs and psymtabs for a file, once a
3396 new psymtab for it has been read.
3397 * coffread.c (end_psymtab): Free named symtabs and psymtabs for
3398 a file, once a new symtab has been read for it.
3399 * mipsread.c: FIXME. We need to do the same for MIPS, but it
3400 looks harder to determine the top-level block before it's been
3401 queued to the psymtab list.
3403 * symfile.c (symbol_file_add): Use filtered printing and wrap it.
3404 If we have wiped out any old symbol tables, clean up at end of
3406 (symbol_file_command): Don't reference symfile_fns if it's zero.
3408 * symtab.h (GLOBAL_BLOCK, STATIC_BLOCK, FIRST_LOCAL_BLOCK): New
3409 defines for the blocks of a blockvector that contain global and
3410 file-static symbols and the first of the smaller scope contours.
3411 * symtab.c (lookup_symbol, find_pc_symtab, find_pc_line,
3412 decode_line_1, make_symbol_completion_list): Use the above.
3413 * coffread.c (end_symtab, patch_opaque_types): Ditto.
3414 * dbxread.c (end_symtab): Ditto.
3415 * expread.y (block): Ditto.
3416 * mipsread.c (throughout): Ditto.
3417 * symmisc.c (free_named_symtabs): Ditto.
3419 * symtab.c (list_symbols): Process the first symbol of the
3420 static psymbols list.
3421 (types_info): Restore this function from its untimely #if 0.
3422 It's not perfect, but it is better than nothing.
3423 (_initialize_symtab): Restore "info types".
3425 Thu Apr 11 05:23:19 1991 John Gilmore (gnu at cygint.cygnus.com)
3427 * m68k-stub.c: Remote stub for 680x0's, created from
3428 rem-m68k.shar (which is removed).
3429 * nindy-share/{Makefile,Onindy.c,blout.h,env.h,nindy.c,ttyflush.c}:
3430 Remove RCS log stuff now that we use CVS and it blows our diffs.
3432 Wed Apr 10 14:18:06 1991 John Gilmore (gnu at cygint.cygnus.com)
3434 * symmisc.c (free_named_symtab): Make it work, in its current
3435 kludgy fashion. Change result to indicate if we blew away bkpts.
3436 * dbxread.c (end_symtab): Accumulate result from
3437 free_named_symtab and print warning if we blew user's state.
3438 * symfile.h: free_named_symtab now returns an int.
3440 Mon Apr 8 23:57:43 1991 John Gilmore (gnu at cygint.cygnus.com)
3442 * dbxread.c (dbx_symfile_read): Initialize psymbol list if this
3443 is the first symbol read, even if not mainline.
3444 (dbx_psymtab_to_symtab): symfile might be zero, cope.
3445 * exec.c (exec_ops): Add_syms_addr is valid in our tvec.
3446 (set_section_command): New command ("section xxx yyy" -- should
3447 be renamed to "set section xxx yyy" FIXME) which sets the
3448 base address of a section of the exec file, overriding the
3449 virtual address that BFD reports.
3451 Fri Apr 5 17:14:39 1991 John Gilmore (gnu at cygint.cygnus.com)
3453 * exec.c: Add add_syms_addr_command to exec_ops, so you can
3454 load symbols at any address while examining an exec file.
3456 Thu Apr 4 10:09:35 1991 John Gilmore (gnu at cygint.cygnus.com)
3458 * tm-i386v.h (FLOAT_INFO): Don't define it, since the code
3459 for printing the float info is host-dependent, not
3460 target-dependent. FIXME.
3461 * i386-pinsn.c: Move #includes to top, remove useless ones.
3462 * i386-tdep.c: Don't bother including <.../reg.h> since we
3463 don't use it (and it doesn't exist on host systems).
3465 * ieee-float.c (ieee_extended_to_double): Convert NaN to Inf.
3466 Convert negative numbers properly.
3467 (ieee_test): Make numbers really random; fix format arg.
3469 * infcmd.c (attach_command, detach_command): Don't repeat on CR.
3470 * core.c (core_detach): Unpush core_ops, which might not be on
3471 top. We used to just pop the top, which broke things. Don't
3472 need dont_repeat() any more.
3473 (core_file_command): Psst! Don't repeat it.
3474 * remote-nindy.c (nindy_detach): Don't need dont_repeat() now.
3475 * expprint.c (print_subexp): Avoid switch fallthru on
3476 BINOP_ASSIGN_MODIFY, so we can print += and such.
3477 * frame.h: Fix typo.
3478 * inflow.c (kill_command): After killing inferior, print our
3479 current frame in the core file, if we have one.
3480 (generic_mourn_inferior): When inferior dies, either select
3481 the current frame (in the new target, e.g. core file), or
3482 set both the current and selected frames to NULL.
3484 Changes from Peter Schauer.
3486 * infptrace.c: Avoid <sys/ptrace.h> on USG.
3488 * Make all file names fit in 14 characters (sigh and damn!):
3489 mv hp300hpux-xdep.c hp300ux-xdep.c
3490 mv symmetry-xdep.c symm-xdep.c
3491 mv symmetry-tdep.c symm-tdep.c
3492 mv convex-opcode.h convx-opcode.h
3493 mv tm-vxworks960.h tm-vx960.h
3494 mv tm-vxworks68.h tm-vx68.h
3495 mv Makefile.srcdir Makefile.sdir
3496 mv gdb-int.texinfo gdbint.texinfo
3497 mv remote-sa.m68k.shar rem-m68k.shar
3498 mv remote-multi.shar rem-multi.shar
3499 * Makefile.dist, README, config.gdb, convex-pinsn.c,
3500 tconfig/symmetry, tconfig/vxworks960, tconfig/vxworks68,
3501 xconfig/hp300hpux, xconfig/symmetry: Change names to shorter
3504 * command.c (user_info_1, user_info): New command for listing
3505 the user-defined commands.
3507 Wed Apr 3 15:00:26 1991 John Gilmore (gnu at cygint.cygnus.com)
3509 * dbxread.c (really_free_pendings): Clear file_symbols
3510 and global_symbols after freeing them; otherwise, running
3511 this function twice (if it appears twice on the cleanup
3512 chain), we try to free things twice.
3514 * dbxread.c (read_dbx_symtab): Calculate end_of_text_addr
3515 based on text_addr (the address of text in core), not on addr (the
3516 offset between text in the .o file and in core). This change
3517 is from Peter Schauer.
3519 * main.c: Define ALL_CLEANUPS as a cast of zero.
3520 (return_to_top_level): Use it.
3521 (main): Do all cleanups after each command run as part
3522 of the gdb startup sequence. Also do all cleanups before
3523 entering the command loop, and every time we exit the command
3524 loop and reenter. Before, the cleanups from the startup sequence
3525 were being left undone until the first error!
3526 (command_loop): Rename do_nothing cleanup to command_loop_marker
3527 so we can see it easily when examining the cleanup chain.
3528 (init_signals): Add another do_nothing for signal handling.
3529 (quit_command): Only try to kill target if it has execution.
3530 Problems in the target stack got us into a state where
3531 inferior_pid was nonzero but none of the targets had execution.
3532 In this state you couldn't exit gdb.
3534 * dbxread.c: Two changes from Peter Schauer.
3535 (echo_command): Fflush output after an echo command.
3536 (show_history): Pass all args to cmd_show_list.
3538 * utils.c (init_malloc): Call mtrace to turn on tracing
3539 if the environment variable MALLOC_TRACE is set to a file name.
3540 * mtrace.c: Add source file which provides a log of every malloc,
3541 free, and realloc to a trace file.
3542 * mtrace.awk: Add source file which analyzes the trace file.
3543 * Makefile.dist (GNU_MALLOC, MALLOCSRC): Add mtrace.{c,o,awk}.
3544 (VERSION): Roll to 3.94.3.
3546 * breakpoint.c (breakpoint_1): Add a space to "i watch" output.
3547 (check_duplicates): Don't bother with watchpoints.
3548 (set_raw_breakpoint): Comment about danger of this routine.
3549 (watch_command): Parse and eval all args before calling
3552 * solib.c (find_solib): Avoid error in referencing memory to
3553 see if any more shared libraries have been added. This is
3554 particularly useful if the target has terminated. Bug reported
3557 Changes from Peter Schauer <pesrem@regent.e-technik.tu-muenchen.de>
3558 in bringing up 3.94.2 on the Sun-3.
3560 * Makefile.dist: Include CFLAGS in rule for cplus-dem.o.
3561 * breakpoint.c (enable_breakpoint): Check for valid watchpoint
3562 expression (in scope) before reenabling watchpoint.
3563 * signame.c (init_sigs): Add missing declaration of i, fix
3564 sys_siglist declaration.
3565 * source.c (list_command): Fixed range computation to use
3567 * stack.c (backtrace_command): Do not allow command if target has
3568 no stack, print informative error message.
3569 * target.c (target_command): Do not write into command line
3570 because this fails if the target command is used in a user defined
3571 command. [This change was enhanced by gnu to support any-
3572 unique-prefix matching on target names.]
3573 * valops.c (value_struct_elt): Avoid infinite loop on an
3574 erroneous attempt to print the member of function (try p main.p).
3576 Mon Apr 1 17:05:45 1991 John Gilmore (gnu at cygint.cygnus.com)
3578 * expread.y (name_no_typename): Avoid reduce/reduce errors
3579 caused by ambiguity in handling NAME_OR_INT and NAME_OR_UINT.
3580 Since the GDB parser really doesn't use name_no_typename in a
3581 name-only context, the parser can't tell the diff between
3582 names and numbers here. Avoid allowing a name_no_typename
3583 to be a NAME_OR_*INT to resolve the conflict.
3585 Sun Mar 31 20:12:07 1991 John Gilmore (gnu at cygint.cygnus.com)
3587 Bugfixes from Mark Fox (markf@wrs.com) (test=testField.c):
3589 * valprint.c (val_print_fields): bitfield printing didn't handle
3590 byte order. Indirect through a few more fns to cope.
3592 * values.c (modify_field): also cope with byte order.
3594 Sat Mar 23 10:02:21 1991 John Gilmore (gnu at cygint.cygnus.com)
3596 Cleanup for release 3.94.2:
3598 * Makefile.dist: Pull REMOTE_OBS. Fix saber includes for BFD
3599 include files. Roll version to 3.94.2.
3601 * coffread.c (init_stringtab): Read length into unsigned char
3602 array before swapping; don't assume 32-bit longs.
3604 * target.c (target_info): Don't bother with get_sym_file, just use
3605 the symfile global variable.
3606 * symtab.h, symfile.c (get_sym_file): Delete it.
3608 * dbxread.c (dbx_symfile_init): Don't depend on long == 4 bytes.
3609 (define_symbol): Set symbol line number to 0 if not gcc-compiled.
3610 (read_type): Replace one more error() with complain().
3612 * mipsread.c (parse_partial_symbols): Replace printf with complain.
3614 * i960-tdep.c: Fix copyright attribution.
3616 * config.gdb: Quote all backquotes in doublequotes. You can
3617 quote me on that. BSD 4.4 shell found this one.
3619 * infptrace.c (throughout): The third argument to ptrace is an
3622 * infrun.c (wait_for_inferior): When program has terminated, we
3623 have to call target_terminal_ours before we pop that target off
3624 the stack (e.g. before a call to target_kill or
3625 target_mourn_inferior). This fixes problem where a program
3626 terminates, then GDB stops for (tty output) and you have to type
3627 "fg" to the shell to resume it. FIXME: This code for what to
3628 do after termination really should be in normal_stop instead.
3630 * gdbcore.h (read_memory_check): Change declaration; it changed
3633 * terminal.h: Include <sgtty.h> before <sys/ioctl.h>, since in BSD
3634 4.4 prereleases, this avoids a bug in their sgtty compatability
3636 * remote.c: Use terminal.h rather than hand-rolling the same.
3638 * signame.c, signame.h (psignal): Arg is unsigned, not int.
3639 * utils.c (strsave, strstr): Fix arg types.
3640 * valprint.c (val_print): lint
3642 MIPS symbol table support from Per Bothner:
3644 * symfile.c (symtab_fns): Remove initializer table that needs to
3645 be hacked for each new symbol file format supported.
3646 (add_symtab_fns): New function, chains symbol table
3647 handlers into the global list.
3648 (symfile_init): Search this list.
3649 * symfile.h: Add next pointer, declare add_symtab_fns.
3650 * coffread.c (_initialize_coffread): Call add_symtab_fns.
3651 * dbxread.c (_initialize_dbxread): Call add_symtab_fns.
3653 * mipsread.c (psymtab_to_symtab_1): return void instead of (struct
3654 symbol *). Thus, we no longer need the hack to trash
3655 pst->filename. Good, since that hack confused code in symfile.c!
3657 (reorder_symtabs, destroy_all_symtabs): Removed static
3658 all_symtabs, which was used to qsort symtabs in reorder_symtabs.
3659 Instead, the latter now uses a temporary array (stack-allocated
3660 from an obstack, and then freed).
3662 (parse_symbol): Added a hack to fix up BLOCK_{START,END} if they
3663 haven't been set in the outermost stBlock of a procedure. This was
3664 a problem with f77 binaries on Ultrix 4.?.
3666 (new_symtab, new_symbol, new_type): Continue changing code to use
3667 obstacks more and otherwise conform to dbxread internal style.
3668 Made the free_code of symtabs be free_linetable (as in dbxread)
3669 instead of free_contents. This implies memory leaks when reading
3670 a new symbol table, until the conversion is finished. Did change
3671 (struct symbol) and (struct type) to be allocated on the
3672 symbol_obstack. Blocks and blockvectors are among the things
3675 * mipsread.c (parse_partial_symbols, parse_fdr): It hasn't been
3676 tested much, but it solved one problem (reported by Meissner), and
3677 cleans up some other things. The problem happened when an
3678 included file contains actual code (functions) and not just
3679 definitions. The mips coff is a little inconvenient there, since
3680 it may cause a procedure to be mapped to the wrong psymtab.
3682 * mips-tdep.c (heuristic_proc_desc): Minor cleanup.
3683 * mips-xdep.c (fetch_core_registers): Minor cleanup. FIXME,
3684 this will need work for the new core paradigm.
3686 Opcode patches from the net:
3688 * mips-opcode.h: fix incorrect disassembly of the mfc1, cfc1, and
3689 ctc1 instructions. Also, the cvt.d.w and cvt.s.w instructions were
3690 missing altogether - they are added here. From Bruce Bauman.
3691 * mips-opcode.h: The low mask for C0 instructions was too small.
3692 From Garrett Lau. I modified the fix to check the entire 32-bit
3695 * ns32k-opcode.h: Fix opcodes for deiw and deid. From Bruce
3698 Thu Mar 21 12:56:46 1991 John Gilmore (gnu at cygint.cygnus.com)
3700 Roll in changes from Per Bothner (Tue, 25 Sep 90 11:11:04):
3702 * dbxread.c (read_type): Pointer subtraction (value_sub in
3703 valarith.c) sometimes failed because the types of the
3704 pointers being subtracted were not identical.
3705 These differed because dbxread.c was allocating pointer types
3706 using dbx_alloc_type+smash_to_pointer_type instead of
3707 lookup_pointer_type. I failed to find a justification for the
3708 former, so I changed it to use the latter. Similarly, I
3709 replaced smash_to_function_type by lookup_function_type,
3710 and smash_to_reference_type by lookup_reference_type.
3712 * mipsread.c (parse_symbol, upgrade_type, parse_procedure,
3713 _initialize_mipsread): corresponding changes.
3715 * symtab.c (smash_to_{pointer,reference,function}_type): eliminate.
3717 * source.c (mod_path): Do tilde_expand on each component of the path,
3718 rather than on the (list of) paths as a whole.
3719 (print_source_lines): Set first_line_listed in addition to
3720 current_source_symtab and current_source_line. If the source was
3721 not findable, after a "dir" command to fix the problem,
3722 a "list" would get the wrong lines.
3724 While I was there... (gnu):
3726 * dbxread.c (read_type): Change error to complaint.
3728 Thu Mar 21 12:56:46 1991 John Gilmore (gnu at cygint.cygnus.com)
3730 First attempt at detailed understanding of symbol table memory alloc.
3732 * dbxread.c (dbx_symfile_read): Free our string table if we
3733 aren't the mainline. Free the "info" struct since we're done with
3735 (init_psymbol_list): Free any previously allocated psymbol lists.
3736 (): FIXME: Should realloc-down the psymbol lists when done reading
3737 the main symbol file?
3739 * symmisc.c (free_symtab): Free fullname field too.
3741 * xm-hp300hpux.h (USG): #undef then #define so Makefile can -D.
3742 (REGISTER_ADDR): Make result type unsigned int.
3744 * xconfig/{i386*,hp300hpux,altosgas,altos}: All config files that
3745 define REGEX must also define REGEX1 (its dependency).
3747 Tue Mar 19 21:28:57 1991 John Gilmore (gnu at cygint.cygnus.com)
3749 * tconfig/i960: No longer works, points you at vxworks960 or
3752 * xgdb.c, XGDB-README: Remove file. Users can get the much
3754 * Makefile.dist: Remove all trace of xgdb.
3756 * breakpoint.c (breakpoint_1): Pass demangle arg to
3757 print_address_symbolic.
3758 (clear_breakpoints): Remove unused function.
3759 (breakpoint_re_set_one): Guts of breakpoint_re_set.
3760 (breakpoint_re_set): Use catch_errors to do them all anyway.
3762 * gdb-int.texinfo (Host versus Target): Add section on what is
3763 a "host" feature versus what is a "target" feature.
3765 * infcmd.c (path_command, path_info): Handle the PATH variable
3766 (object search path) as conveniently as the source search path.
3767 * environ.c (set_in_environ): Set some vars in GDB's environment,
3768 in addition to the child's. PATH, G960BASE, G960BIN for starters.
3769 * source.c (mod_path): New function, from guts of
3770 directory_command, modifies a path. Used by path_command.
3771 (directory_command): Call it.
3772 * defs.h (strsave): Declare.
3774 * utils.c (sevenbit_strings): Add new printing option.
3775 (printchar): Use it.
3776 (strsave): Provide this handy helper routine.
3777 (set_width_command): Rename set_screen_width_command.
3778 (_initialize_utils): "set screen-width" => "set width";
3779 "set screen-height" => "set height"; add sevenbit-strings.
3781 * infcmd.c (do_registers_info): Print floating point registers
3782 in raw hex as well as float format, regardless of whether it is
3783 a "virtual" convertible register.
3784 * tm-sparc.h (PRINT_REGISTER_HOOK): Print every pair of float
3785 regs as a double, just in case it's being used that way.
3786 * values.c (unpack_long): Comment on array/function coercion.
3787 (unpack_double): Argument is in target byte order now. For
3788 integer arguments, just call unpack_long and float the result.
3789 * m68k-tdep.c: include defs.h for "const" handling.
3790 * remote-nindy.c: Use ieee-float stuff.
3791 (nindy_fetch_registers): Unpack double regs to host double, then
3793 (nindy_store_registers): Pack extendeds to host double, flip
3794 around by misusing unpack_double, send as target double.
3796 * tm-vxworks68.h (FRAME_CHAIN): Handle current frame pointer of
3797 zero, as when stopped at the first instruction of a process.
3799 * blockframe.c: Fix filename in comment (param.h => tm.h).
3800 * sparc-tdep.c (skip_prologue): More explicit nudging comments.
3801 * tm-68k.h: Fix typos.
3803 Fri Mar 15 01:09:34 1991 John Gilmore (gnu at cygint.cygnus.com)
3805 Changes from a bringup on the DEC Vax under Ultrix 4.0.
3807 * coredep.c (fetch_core_registers): Pass end-address of register
3808 section to register_addr as expected. Don't call supply_register
3809 if we'd just pass it garbage.
3811 * dbxread.c (read_dbx_symtab): Skip N_NSYMS on Ultrix.
3813 * exec.c (xfer_memory): Use boolean xfer_fn result, not int.
3815 * target.c (push_target, target_info): Cast enums to int for < or
3818 * stack.c (print_frame_info): Identify source file & line
3819 even if we can't print it.
3821 * xm-vax.h (MISSING_VPRINTF): No longer missing in Ultrix V4.0.
3823 Sat Mar 9 10:08:20 1991 John Gilmore (gnu at cygint.cygnus.com)
3825 Clean up IEEE floating point support.
3827 * ieee-float.h: New file.
3828 * ieee-float.c: Write real routines to convert between host
3829 doubles and various target IEEE extendeds.
3830 * m68k-xdep.c: Eliminate assembler code for extended floats.
3831 * xconfig/{3b1,altos,altosgas,hp300bsd,isi,news,news1000,sun2os3,
3832 sun2os4,sun3,sun3os3,sun3os4}: Eliminate use of m68k-xdep.o.
3833 * tm-i960.h, tm-68k.h (REGISTER_CONVERT_TO_VIRTUAL,
3834 REGISTER_CONVERT_TO_RAW): Use ieee_extended_to_double and
3835 double_to_ieee_extended.
3836 * i960-tdep.c: Define ext_format_i960.
3837 * m68k-tdep.c: Define ext_format_68881.
3838 * sparc-tdep.c: Define ext_format_sparc, though unused.
3839 * Makefile.dist (HFILES): Add ieee-float.h.
3840 * inftarg.c: #include "ieee-float.h" for the REGISTER_CONVERT
3843 Obsolete the "coffstrip" program in favor of using BFD's strip.
3845 * nindy-share/coffstrip.c: Remove file.
3846 * nindy-share/nindy.c (coffstrip): Routine to run bfd_strip.
3847 * Makefile.dist: Remove references to nindy-share/coffstrip.c.
3848 * tconfig/nindy960: Remove reference to coffstrip.o.
3850 * Makefile.dist: Roll version number to 3.94.1 (not yet final).
3852 Wed Mar 6 09:56:45 1991 John Gilmore (gnu at cygint.cygnus.com)
3854 * symfile.h: Add symfile_bfd, common between dbxread and coffread.
3855 * dbxread.c: Remove static symfile_bfd.
3856 * infcmd.c (do_registers_info): Add PRINT_REGISTER_HOOK, though
3858 * inftarg.c (child_detach): Pop the child_ops vector if the
3859 detach is successful.
3860 * remote-nindy.c (nindy_create_inferior): Don't push a new
3861 nindy_ops since nindy uses the same one for execution and memory
3863 * core.c (core_ops): Use child_attach and child_create_inferior
3864 rather than default attach and create_inferior functions.
3866 Handle floating point registers in core files.
3868 * sparc-xdep.c (fetch_core_registers): Rewrite for float support.
3869 * sun3-xdep.c (fetch_core_registers): Rewrite for float support.
3870 This version untested since BFD doesn't yet support sun3 core
3872 * hp300hpux-xdep.c: Rewrite fetch_core_registers to new calling
3873 conventions. Fix comments and style. This version has not
3874 been compiled yet, since we have no HP inhouse.
3875 * core.c (get_core_registers): Look for two sections, ".reg"
3876 and ".reg2", and pass both to fetch_core_registers sequentially.
3878 Revise directory path yet again.
3880 * source.c (forget_cached_source_info): Not static any more.
3881 (init_source_path): New default source path is "$cdir:$cwd".
3882 (dir_command): Handle variable arguments ($cdir, $cwd).
3883 (source_info): Print "Compilation directory" rather than
3884 "Originally compiled in" to remind people of $cdir.
3885 (openp): If the path contains $cwd, use current directory.
3886 (open_source_file): If compilation directory is known, replace
3887 first $cdir in path with the compilation directory.
3888 (print_source_lines): Even if we can't print the lines, set the
3889 current symtab and line for future commands like "info source" or
3890 "breakpoint". Also, error message now contains the file name,
3891 line number, and file access error message.
3892 (_initialize_source): Fix help text to describe changes.
3893 * main.c (cd_command): Forget cached source info when we chdir.
3894 * utils.c (strstr): Add simple implementation.
3896 Tue Mar 5 01:41:40 1991 John Gilmore (gnu at fowanton.cygnus.com)
3898 * coffread.c (read_one_sym, init_linetable, init_stringtab):
3899 Byte-swap COFF symbol tables if necessary when reading them in.
3900 Use complain() to replace error message in one spot. Needs
3901 corresponding change in bfd/coff-code.h to make some symbol
3902 swapping routines non-static.
3904 Mon Mar 4 00:53:40 1991 John Gilmore (gnu at cygint.cygnus.com)
3906 Merge changes from Eirik Fuller, for UTek.
3908 * defs.h (errno): Add declaration.
3909 * altos-xdep.c, arm-xdep.c, convex-xdep.c, gould-xdep.c,
3910 hp300hpux-xdep.c, infrun.c, inflow.c, infptrace.c, i386-tdep.c,
3911 i386-xdep.c, pyr-xdep.c, mips-xdep.c, remote-eb.c, remote-nindy.c,
3912 remote-vx.c, source.c, standalone.c, stuff.c, sun386-xdep.c,
3913 symmetry-tdep.c, symmetry-xdep.c, umax-xdep.c, utils.c: Eliminate
3914 declarations of errno.
3916 * remote-eb.c: Define B19200 and B38400 as EXTA and EXTB.
3918 * remote-vx.c: Include <sys/time.h> for UTek; Sun gets it via
3919 <rpc/rpc.h> and <rpc/types.h>.
3921 Sat Mar 2 15:47:55 1991 John Gilmore (gnu at cygint.cygnus.com)
3923 * i960-tdep.c (examine_prologue): Add new argument limit,
3924 which stops the scan at the end of the prologue, or at the PC.
3925 This fixes a problem where it walks down into the code for the
3926 user's statements if that code looks like function prologues.
3927 Mark Fox and I have been bouncing this code back and forth, making
3928 small changes to it. Callers changed to match.
3930 Tue Feb 26 01:47:07 1991 Cygnus John Gilmore (cygnus at yuba)
3932 Cleanup for gdb-3.94 release final:
3934 * Makefile.dist: Remove remote-vx.c, remote-nindy.c, and all
3935 the .c files from vx-share and nindy-share, from the various
3936 macros, since they are not found via ALLDEPFILES.
3937 (SFILES): Add tm-i960.h.
3938 (alldeps.mak rule): Break out ALLDEPFILES_MAINDIR and
3939 ALLDEPFILES_SUBDIR. List all the nindy and vxworks subdir files
3941 (TAGFILES_MAINDIR): Change ALLDEPFILES to ALLDEPFILES_MAINDIR.
3942 (gdb.tar.Z): Use ALLDEPFILES_SUBDIR as well as SFILES_SUBDIR.
3944 Mon Feb 25 16:02:35 1991 Cygnus John Gilmore (cygnus at oldman)
3946 * am29k-tdep.c: Add contribution line.
3947 (examine_prologue): Cache information about function prologues in
3948 the misc-function-vector to avoid lots of references over the
3949 serial line while examining instructions.
3951 * core.c (core_close): New function made from cleanup_core.
3953 * core.c, exec.c, inftarg.c, remote-eb.c, remote-nindy.c,
3954 remote-vx.c, remote.c, target.c, target.h,
3955 Update target_ops vector to add attach, close, and load entries.
3956 Use add_syms_addr_command, not add_file_addr_command, for
3957 add_file. Break out close routine from existing code.
3959 * dbxread.c (really_free_pendings): Don't free pending_blocks;
3960 they are in an obstack.
3961 (read_dbx_symtab): Relocate end_of_text_addr in the psymtab.
3963 (define_symbol): Add symbol type parameter; change callers;
3964 pass type parameter to DBX_PARM_SYMBOL_CLASS macro to allow
3965 it to influence the symbol class on the i960.
3966 (define_symbol): Swap LOC_CONST's into target byte order.
3968 * exec.c (exec_close): New function.
3969 (exec_file_command): Call it.
3971 * findvar.c (read_relative_register_raw_bytes): Doc byte order,
3972 Fix byte order of frame pointer.
3973 (read_var_value): Result of 0 if var's value can't be found,
3974 e.g. missing FRAME_ARGS_ADDRESS. Byte-swap LOC_CONST and
3975 LOC_LABEL values to target order. Add LOC_LOCAL_ARG.
3976 (locate_var_value): Use read_var_value and use its lazy address
3977 as the location of the var's value. Lint.
3979 * i960-pinsn.c (next_insn): Add routine from vxgdb for scanning
3982 * i960-tdep.c (arg_address, i960_frame_find_saved_regs): Remove
3983 obsolete Intel versions in favor of vxgdb versions.
3984 (check_host, byteswap, byteswap_val, reorder_val): Eliminate
3985 code dealing with byte order of values, which Intel did in host byte
3986 order rather than gdb-4's target byte order.
3987 (i960_frame_chain_valid): Move to nindy-tdep.c.
3988 (examine_prologue, skip_prologue, frame_find_saved_regs,
3989 frame_args_address, leafproc_return, saved_pc_after_call,
3990 pop_frame): Add vxgdb versions from Mark Fox.
3991 (examine_prologue, frame_struct_result_address): Add code
3992 to deal with the saved value of G13 (struct return address
3994 (frame_args_address): Modify Mark's version to prefer the
3995 saved value over the current value in the topmost frame.
3996 Cache result in the frame info to avoid performance hair in
3998 (print_fault): Add gdb960 code for printing faults.
3999 (_initialize_i960): Actually call check_host.
4001 * ieee-float.c (ieee_extended_to_double, ieee_double_to_extended):
4002 add stub routines. FIXME, these currently just return zero!
4004 * infcmd.c (program_info): Use PRINT_RANDOM_SIGNAL.
4005 (attach_command): Call target_attach, not target_open, now.
4007 * infrun.c (normal_stop): Make global, not static, for vx_attach.
4008 (child_attach): Rename from child_open.
4009 (wait_for_inferior): Use PRINT_RANDOM_SIGNAL. If stop_pc is zero,
4010 don't confuse it with a zero step_resume_break_address.
4012 * inftarg.c (child_detach): Eliminate inferior_pid test.
4013 (child_files_info): Clean up message a bit.
4014 (child_ops): Use child_attach, not child_open, to attach.
4016 * mem-break.c: #ifdef out the whole file if BREAKPOINT is not
4017 set (e.g. on VxWorks or NINDY). Move read_memory_nobpt from
4018 findvar.c to here, since it depends on the contents of the
4019 shadow_contents of breakpoints, but keep if #if 0 since it is
4022 * nindy-tdep.c: New file, contains nindy_frame_chain_valid, moved
4025 * printcmd.c (address_info): Handle LOC_LOCAL_ARG. Lint.
4026 (ptype_command, display_command): Eliminate have_inferior_p and
4027 have_core_file_p in favor of target_has_stack or
4028 target_has_execution.
4029 (print_frame_args): Handle LOC_LOCAL_ARG. Eliminate duplicate
4030 code for actually finding the values of arguments, though we still
4031 keep track of the maximum stack offset for use in printing unnamed
4032 arguments. Handle missing FRAME_ARGS_ADDRESS.
4034 * remote-nindy.c (i960_print_fault): Move to i960-tdep.c.
4035 (struct nindy_regs): Define registers passed to/from nindy.
4036 (nindy_fetch_registers, nindy_store-registers): Translate between
4037 nindy and GDB formats for the registers.
4038 (dcache_init): Statically allocate the cache, since it was being
4039 allocated by a malloc that was never freed anyway.
4040 (nindy_create_inferior): Error, not core dump, if no exec file.
4041 (nindy_before_main_loop): Use target_load, not target_add_file.
4043 * remote-vx.c (net_load): Specify large timeout for load
4044 requests. Allow user to break out with INTERRUPT.
4045 (net_break): Remove useless code, clean up. Change callers.
4046 (parse-args, skip_white_space, find_white_space): Clean up arg
4047 parsing to cope with quoted strings.
4048 (net_wait, net_quit): Never call error, just return status.
4049 (vx_read_register, vx_write_register): Cleanup status checking.
4050 #ifdef the code based on which CPU we are using (960 or 68k),
4051 FIXME, this should be completely general but it isn't yet.
4052 (vx_xfer_memory, vx_resume): Cleanup status checking.
4053 (vx_run_files_info): Improve message.
4054 (vx_load_command): Renamed from vx_add_file_command. Allow load
4056 (net_ptrace): Remove unused routine.
4057 (vx_wait): Adopt code from vxgdb960 to cope with broken
4058 connections to target machine and prompt to disconnect. Remove
4059 debug printouts. Map some EVENT_'s to SIGnals.
4060 (add_symbol_stub, vx_open): Print names of object files we found,
4061 and "ok" if we read their symbols OK. Clarify output in general.
4062 (vx_attach, vx_detach, vx_kill): Add these commands.
4063 (vx_convert_from_virtual, vx_convert_to_virtual): Simplify.
4064 (vx_run_ops): Turn off all_mem, to avoid spurious msg in the
4065 "info files" output, and create_inferior, since we already have
4068 * stack.c (frame_info): Replace Frame_unknown with 0.
4069 (print_frame_arg_vars): Handle LOC_LOCAL_ARG.
4070 (return_command): Pop until the PC matches as well as the FP,
4071 so it works even if the FP is shared with another function,
4072 as in "frameless" or "leaf" procedures.
4074 * symfile.c (load_command): renamed from add_file_target_command.
4075 (add_syms_addr_command): renamed from add_file_addr_command.
4076 (add_syms_command): Stub to call target_add_syms.
4077 (_initialize_symfile): Change command names and descriptions,
4078 add-file => add-syms, and load from alias to its own command.
4080 * target.c (kill_or_be_killed, maybe_kill_then_attach,
4081 maybe_kill_then_create_inferior): Default for attempts to start
4082 a process, if one is already running, is to ask about killing
4083 it and retry if yes.
4084 (upstack_create_inferior): #if-0 it, strata obsolete it.
4085 (push_target, unpush_target, pop_target): to_close() a target
4086 before unstacking it.
4087 (target_info): Renamed from target_files_info.
4088 (_initialize_targets): Rename "i files" as "i target", accessible
4091 * target.h: Improve comments about the target_ vectored routines.
4093 * tm-i960.h: Remove NINDY-specific stuff to tm-nindy960.h.
4094 Convert commenting style to standard GNU style.
4095 (DBX_PARM_SYMBOL_CLASS): allow LOC_LOCAL_ARG's to be recognized.
4096 (SKIP_PROLOGUE): No longer a no-op.
4097 (SAVED_PC_AFTER_CALL): Now handles leaf procedures.
4098 (*_REGNUM): Sort register numbers.
4099 (REGISTER_BYTES, REGISTER_BYTE, REGISTER_RAW_SIZE,
4100 MAX_REGISTER_RAW_SIZE, REGISTER_CONVERTIBLE,
4101 REGISTER_CONVERT_TO_VIRTUAL, REGISTER_CONVERT_TO_RAW): Float regs
4102 are now 10 byte extendeds, not 8 byte doubles.
4103 (FRAME_CHAIN_VALID): Make this config-dependent, since it differs
4104 for nindy versus vxworks targets. FIXME, this should possibly go
4105 in the target vector.
4106 (EXTRA_FRAME_INFO, INIT_EXTRA_FRAME_INFO): Cache both
4107 frame_saved_regs and arg pointer with each frame.
4108 (FRAMELESS_FUNCTION_INVOCATION): New leafproc support.
4109 (FRAME_ARGS_ADDRESS): Use cached result.
4110 (FRAME_ARGS_ADDRESS_CORRECT): New, avoids g14 guessing.
4111 (FRAME_FIND_SAVED_REGS): Change arg to subsidiary fn.
4112 (PRINT_RAMDON_SIGNAL): Call print_fault.
4113 (POP_FRAME): Now works.
4115 * tm-nindy960.h: Break this off tm-i960.h. NINDY-specific
4116 option parsing and startup; STACK_END_ADDR, FRAME_CHAIN_VALID,
4117 BREAKPOINT, and DECR_PC_AFTER_BREAK are here.
4118 (ADDITIONAL_OPTION_HANDLER): use target_load, not
4121 * tm-vxworks960.h: Break this off tm-i960.h. VxGDB specific
4122 startup; DECR_PC_AFTER_BREAK, and FRAME_CHAIN_VALID are here.
4124 * valarith.c (value_subscripted_rvalue): Avoid handling
4125 floats and doubles specially; it gave alignment errors. Lint.
4127 * valops.c (value_of_variable, value_of_this): Error if unknown
4130 * valprint.c (print_floating): Bcopy rather than pointer-deref,
4131 to avoid alignment problems.
4132 (value_print): Handle unknown value address.
4133 (cplus_val_print): Two args are ignored; remove them. Change caller.
4134 (val_print): Use unpack_long rather than pointer-deref.
4137 (unpack_long, unpack_double): Use bcopy rather than pointer-deref
4138 to avoid alignment problems.
4139 (value_being_returned): Error if return value unknown.
4140 (set_return_value): Add bogosity warning, FIXME. *
4142 * TODO: A woman's work is never done.
4144 * Makefile.dist: Distribute REMOTE_OBS into tconfig files.
4145 Separate INCLUDE_CFLAGS for use with lint. Add LINTFILES.
4146 Add ieee-float.o to OBS.
4147 * tconfig/{nindy960,vxworks68,vxworks960}: Include the desired
4148 REMOTE_OBS remote-interface files in the TDEPFILES and TM_FILE.
4149 * tconfig/i960: FIXME. Half-merge, produce warning if config'd.
4151 Changes to generalize the VxWorks RPC protocol slightly, to handle
4152 i960 as well as 68000.
4154 * vx-share/dbgRpcLib.h (VX_SOURCE_STEP): Add.
4155 * vx-share/reg.h: Produce i960 regs #ifdef I80960
4156 * vx-share/xdr_ptrace.c: Skip FPA registers if 960.
4157 * vx-share/xdr_rdb.h: Add SOURCE_STEP struct and xdr decl.
4158 * vx-share/xdr_rdb.c: Add xdr_SOURCE_STEP routine.
4159 * vx-share/xdr_regs.c: Add xdr_regs, xdr_fp_status, xdr_ext_fp
4160 for i960. Change xdr_vectors to xdr_opaques for 68k registers,
4161 so they will move in target byte order rather than network
4162 byte order (happens to be the same).
4164 Mon Feb 25 03:41:44 1991 John Gilmore (gnu at cygint.cygnus.com)
4166 * tm-convex.h (END_OF_TEXT_DEFAULT): Remove #if 0'd block.
4168 Sun Feb 24 00:55:53 1991 John Gilmore (gnu at cygint.cygnus.com)
4171 Add contribution lines to various files, showing where they
4174 * breakpoint.c (break_insn, check_break_insn_size,
4175 read_memory_nobpt): Remove to mem-break.c.
4177 * xm-*.h, param-no-tm.h, tm-29k.h, valprint.c: Change BYTE_ORDER to
4180 * tm-29k.h (STAB_REG_TO_REGNUM): Warn user if symbol table
4181 entry has bad register number. This change is not
4182 tested in this release, FIXME.
4184 * frame.h: Eliminate Frame_unknown in favor of a simple zero.
4187 * value.h: Force value's contents field to be aligned to hold
4188 at least a double or a long long (if supported). This avoids
4189 doing bcopy's in and out of the contents field.
4191 (step_1): Avoid coredump under obscure circumstances when we
4194 * symtab.h (misc_info): Add field to misc function vector for
4195 any kind of cached information the target code desires. AMD
4196 29000 uses this to avoid repeating examine_function_prologue's.
4198 * coffread.c: Lint. Remove static symfile, read_section_header.
4199 core.c (have_core_file_p): Lint: remove.
4200 expprint.c (print_subexp): Lint.
4201 infptrace.c, valops.c, valprint.c: lint.
4203 Roll in changes from vxgdb-5.0.1:
4205 * symtab.h: Comment byte order of each address class. Add
4206 LOC_LOCAL_ARG for frame-relative args (960).
4207 expread.y: Use LOC_LOCAL_ARG where LOC_ARG is used.
4208 symtab.c, symmisc.c: ditto.
4210 * infrun.c (init_wait_for_inferior): Clear stop_signal.
4212 * remote.c (remote_resume): Error if resume with a signal.
4214 * symfile.c (prim_record_misc_function): Clear misc_info.
4215 (fill_in_vptr_fieldno): Check stub type of arg.
4217 * valops.c (value_cast): Avoid looking up names of types whose
4218 name we don't know, to prevent coredump. Sun CC produces typedef
4219 rtx and the name of *rtx is zero...
4221 Mon Feb 18 21:16:25 1991 John Gilmore (gnu at cygint.cygnus.com)
4223 Roll in changes from final AMD 29000 port (Tiemann).
4225 tconfig/am29k: Add COFF_ENCAPSULATE and TARGET=TARGET_AM29K
4226 for ../include/a.out.encap.h. This might not work now that BFD
4227 is separately compiled. Instead, BFD support for encap will have
4228 to translate machine type 29k into the right COFF_MAGIC.
4230 * infcmd.c: Remove references to inferior_pid that aren't used
4231 in actual ptrace calls; use target_has_execution, etc.
4232 (have_inferior_p): Remove function.
4233 (program_info): Print target info rather than "process number";
4234 avoid gratuitous messages unless from_tty.
4235 (run_stack_dummy, finish_command): Set proceed_to_finish.
4236 infrun.c: Remove inferior_pid refs. Decl & init proceed_to_finish.
4237 main.c: Lint. Lose have_inferior_p().
4238 inferior.h (have_inferior_p): Remove, lint.
4239 (proceed_to_finish): Add flag to ask that all regs be saved
4240 by normal_stop, for the few commands that need it, speeding up
4241 serial I/O. Add comments to stop_registers.
4243 * remote-eb.c: Remove newline from breakpoint message we grep
4244 for. Never time out when running the user program.
4248 Wed Feb 13 15:34:40 1991 John Gilmore (gnu at cygint.cygnus.com)
4250 Roll in changes from vxgdb-5.0.1:
4252 * dbxread.c (read_dbx_symtab): If we encounter a "FORTRAN COMMON"
4253 symbol in its raw form, we are processing an unlinked ".o" file.
4254 See if the target environment has assigned it an address, using
4255 target_lookup_symbol (VxWorks does), and enter it into the symtab
4258 * tm-vxworks.h (FRAME_CHAIN, FRAME_CHAIN_VALID): Override usual
4259 68k versions for a simpler version that assumes zero FP at bottom.
4260 Fixes bug of truncated stack reports.
4262 * target.h (target_lookup_symbol): Define this routine's args
4263 and result, finally.
4265 * target.c (nosymbol): Default routine for target_lookup_symbol.
4266 (target_default): Default lookup_symbol and call_function too.
4267 (files_info): Only print has_all_memory warning if a non-dummy
4270 * remote-vx.c (vx_read_register, vx_convert_to_virtual,
4271 vx_convert_from_virtual): If target does not have floating point,
4272 zero register "values", and avoid doing cross-net conversions.
4273 (vx_lookup_symbol): Rename net_lookup_symbol, add to vectors.
4274 (vx_open): Rearrange code that attaches to target and reads
4275 symbols for all loaded modules, to work if some of the modules
4276 are not accessible. Add symbol_stub() and add_symbol_stub()
4277 as callbacks from catch_errors(). Allow connect attempt to be
4278 interrupted painlessly with ^C (FIXME, there are still some bugs
4279 if the interrupt happens during symbol reading.). Print
4280 final message with puts_filtered, since symbol messages are
4285 * main.c (catch_errors): Only print errstring if non-null.
4286 (command_loop): Avoid an ioctl per command to test ISATTY.
4288 * remote-vx.c (net_load): make static; avoid sophomoric msg.
4289 (vx_xfer_memory): Return correct result!
4290 (vx_files_info): Indicate whether target has float or not.
4291 (vx_lookup_symbol): Complain, not error, if target gone.
4292 (vx_open): Print "Connected" msg before disabling immediate-quit.
4293 [FIXME: lookup_symbol and vx_open changes need testing.]
4295 target.c, remote-eb.c, inftarg.c, am29k-opcode.h, target.h,
4296 tm-29k.h, tmm-vxworks68.h, symfile.c, gdb-int.texinfo: Add
4297 contributor lines and update copyrights to 1991.
4299 Changes from an attempted H-PUX host port:
4301 * infptrace.c (PT_ATTACH, PT_DETACH): Handle HP/UX, which
4302 defines PT_ATTACH and PT_DETACH but not PT_KILL.
4303 * remote-eb.c (eb_open): Misplaced endif kills sysv H/PUX.
4304 * remote-vx.c: include <sys/time.h> for HPUX.
4305 * hp300hpux-xdep.c (fetch_core_registers): Rewrite old
4306 "core_file_command" routine to BFD regime. May not work yet.
4308 Attempted port of "gdb-3.4 Van Jacobson xgdb" to modern gdb.
4310 * xgdb.c: Replace X10 version with some VJ version.
4311 (FIXME: Its copyright assignment is not on record.)
4312 * xgdb.c: Update include files to X11R4 (Xaw crud).
4313 (xgdb_display_source, create_text_widget): fix call to
4314 get_filename_and_charpos. Rewack source window stuff for X11R4
4315 (gleaned from include files, and "nm's" of binary libraries, since
4316 I had no doc available).
4317 (append_selection, append_selection_word): Disable with FIXME
4318 since R4 changed interface here.
4319 (create_buttons): Add back the old set of buttons.
4320 (xgdb_create_window): Fix call to XtInitialize (&argc not argc).
4322 * Makefile.dist (xgdb, xgdb-init.c): Update for X11R4 on Suns.
4323 Roll VERSION to 3.94 (not yet final though).
4325 Sat Feb 9 09:46:25 1991 John Gilmore (gnu at cygint.cygnus.com)
4327 * obstack.h (obstack_ptr_grow, obstack_ptr_grow_fast,
4328 obstack_int_grow, obstack_int_grow_fast): Eliminate
4329 cast on left of assignment, which gives MIPS cc fits and is
4332 * sparc-pinsn.c (print_insn): Eliminate 'set' test, subsumed by
4333 F_ALIAS. Use printf, not fprintf, when not passing a file
4335 (compare_opcodes): Check that identical instructions have
4336 identical opcodes, complain otherwise.
4338 * sparc-opcode.h (st %fsr): Fix opcode "lose" mask. This
4339 was reported by Roland McGrath.
4340 (unimp): Only match if exactly zero instruction. (Roland)
4341 (branches and traps): Generate all variations of these
4342 instructions with macros, based on a single call that defines
4343 each condition name and its binary representation.
4344 (set): Turn on alias bit, to avoid test in sparc-pinsn.c.
4346 * valprint.c (val_print_fields): Take, and use, format parameter.
4347 This means that "p/x struct" again prints the elements in the
4348 desired format. Changed callers.
4350 * stack.c (frame_info): Use filtered output, and indicate wrap
4351 points. Remove kludgy formatting designed to avoid line wrap.
4353 * utils.c (wrap_here): If the line is already full (because
4354 we had printed a long indent or long wrapped string), do an
4355 immediate newline-and-indent.
4357 * m68k-pinsn.c (print_insn_arg): Bugfix from
4358 ntmtv!thompson@ames.arc.nasa.gov (Mike Thompson): 'bkpt #0'
4359 instruction is incorrectly disassembled as bkpt #8.
4361 * dbxread.c (end_psymtab): Bugfix from Peter Schauer
4362 <pesrem@regent.e-technik.tu-muenchen.de>: If you want to set a
4363 breakpoint in a *.y file gdb will say Reading in symbols for *.y...
4364 and then will dump core (sometimes). I traced it back to an
4365 uninitialized symfile_name in psymtab_to_symtab.
4366 (const_vol_complaint): Add quotes to message.
4367 (define_symbol): Only believe line number if gcc_compiled.
4368 Avoid allocating symbol if we will not return it.
4370 Add target strata support so that newly established targets go
4371 into their right place in the target stack (e.g. a new exec file
4372 doesn't wipe out the ability to access the running process).
4374 * target.h, core.c, exec.c, inftarg.c, remote-eb.c,
4375 remote-nindy.c, remote-vx.c, remote.c, target.c: Add to_stratum
4376 and initialize it properly in all the targets.
4378 * target.h: Document strata. Change return type of push_target.
4380 * target.c (nomemory): new function for dummy memory access.
4381 (tcomplain): Rename complain, now also used in symfile.c.
4382 (push_target): Push targets within strata. New return value shows
4383 whether new target is on top of stack or not. Always keep dummy
4385 (target_files_info): Ignore dummy target.
4387 * core.c (core_open): Warn user, and skip accessing file, if the
4388 core target is not the topmost target in the stack.
4389 * remote-nindy.c (nindy_create_inferior): Avoid unpush_target, now
4392 * remote-vx.c: Remove vx_prepare_to_store from vxworks memory
4393 target_ops, it doesn't belong there since we have no regs there.
4394 Change name of target from machine => memory to clarify.
4396 Thu Feb 7 16:32:09 1991 John Gilmore (gnu at spiff.cygnus.com)
4398 * Freeze version 3.93 for release.
4400 * Makefile.dist: Handle vx-share and nindy-share subdirs
4401 properly when building gdb.tar.Z.
4403 * symtab.c: lint; add no_symtab_msg to consolidate the messages
4404 printed in various places, so I could change just one copy.
4406 * dbxread.c, coffread.c: Change references to bfd->iostream
4407 to cast to FILE *, now that BFD avoids needing types defined
4408 in other header files.
4410 Tue Feb 5 21:39:35 1991 John Gilmore (gnu at cygint.cygnus.com)
4412 * command.c, dbxread.c, expprint.c, infcmd.c, infptrace.c,
4413 infrun.c, printcmd.c, remote-nindy.c, source.c, sparc-tdep.c,
4414 sparc-xdep.c, symfile.h, symmisc.c, utils.c, valprint.c: Lint
4415 (actually gcc -Wall).
4417 * dbxread.c: Remove first_global_sym, last_global_sym, since
4418 they are never referenced.
4420 * defs.h (baud_rate): Declare.
4421 main.c: Define it, and add the -b option to set it.
4423 * gdb-int.texinfo: Add text on how to define a new host or target
4424 architecture, prompted by Per Bothner's questions about MIPS
4427 * gdb.texinfo: Document "complaints". Change doc of -q since
4428 gdb no longer prints the copyright and blurb if you specify a file
4429 name to be debugged (just like Emacs). Add doc for Nindy-specific
4430 command line flags for specifying target serial port and such.
4431 Update copyright to 1991.
4433 * gdbcore.h: Remove a large mass of now-useless crud, since BFD
4434 has taken over for us the job of ripping up executable files. The
4435 crud caused Per Bothner's port to not compile.
4437 * infrun.c (normal_stop): Avoid printing "Program exited
4438 normally" if we are in batch mode. This allows a GDB which
4439 executes a program on a target system, to behave like a Unix
4440 command (input from stdin, output to stdout, no extraneous
4443 * main.c (main): Allow additional machine-dependent command line
4444 options to be specified with the ADDITIONAL_OPTIONS,
4445 ADDITIONAL_OPTION_CASES, ADDITIONAL_OPTION_HELP, and
4446 ADDITIONAL_OPTION_HANDLER macros. Also allow machine-dependent
4447 processing to occur just before the main loop with
4448 BEFORE_MAIN_LOOP_HOOK.
4449 (main): If a "core file" argument is specified, and it is not a
4450 core file, try it as a process ID to attach.
4451 (symbol_completion_function): Attempt to cope with
4452 "show screen-" TAB, not very successfully. This needs more work,
4454 (batch_file): New function, returns whether we are reading
4455 commands from an interactive tty on stdin, or from somewhere else.
4456 Called by normal_stop since it doesn't get from_tty passed down
4457 to it like many commands do.
4459 * remote-nindy.c: Handle command line options for nindy
4461 (nindy_before_main_loop): Prompt user for tty name if they
4462 don't specify it before getting to the interactive command loop.
4464 * tm-i960.c: Add ADDITIONAL_OPTIONS, etc, to handle -O, -brk,
4465 and -r command line options. Also add hook before main loop
4466 to make it easy to specify a tty.
4468 * TODO: More things to do, one done.
4470 Mon Feb 4 23:57:39 1991 John Gilmore and Mike Tiemann (at cygint.cygnus.com)
4472 * dbxread.c: Make complaint() calls pass pointer, not struct.
4473 Add complaints about badly formatted C++ type information
4474 (const/volatile indicator, and parse errors resulting in
4475 error_type). Fix C++ virtual member fn comment.
4476 (read_struct_type): Avoid bumping pointer if we got a parse
4477 error; this prevents our walking beyond the end of a string.
4478 Terminate loop on null char as well as semicolon.
4479 (process_one_symbol): Fix the LBRAC fix so that it uses the
4480 last previous SLINE, FUN, or SO record's PC address. C++ debug
4481 symbols did not have SLINE records in a useful order compared
4482 to the LBRAC records.
4483 (define_symbol): Handle "catch" records.
4485 * symtab.c (check_stub_type): Added new complain
4486 `stub_noname_complain' and added a consistency check to
4487 keep the debugger from crashing when finishing from an
4488 exception frame. A real fix will be needed later.
4490 Sat Feb 2 10:43:05 1991 John Gilmore (gnu at cygint.cygnus.com)
4492 * infcmd.c (attach_command): Make global.
4494 * Makefile.dist (REMOTE_OBS): Make these compile by default,
4495 but make them easy to comment out. Perhaps later they should
4496 be enabled by what CPU you configure for? FIXME.
4497 (VERSION): Roll to 3.93.
4498 (pinsn.o): Remove rule for obsolete file.
4499 (dbxread.o,coffread.o,mipsread.o): Use ${srcdir} explicitly.
4501 Run down a problem that manifested by printing the wrong function
4502 name in stack traces of read_ofile_symtab. Turned out that the
4503 problem was the SunOS 4.1.1 (and previous) C compiler outputs
4504 the LBRAC symbol with an address in the *data* segment, which
4505 blew our binary search through the blocks.
4507 * dbxread.c: Use the complain() facility consistently to bitch
4508 about problems in the symbol file we are reading.
4509 (finish_block): Add code to check the nesting of the blocks;
4510 complain and Procrust them to fit if wrong.
4511 (make_blockvector): Check the order of the blocks, complain
4512 [but don't cope] if wrong.
4513 (process_one_symbol): ifndef SUN_FIXED_LBRAC_BUG, check LBRAC
4514 symbols to be sure their PC value is greater than the last SLINE
4515 (line number) symbol we've seen, complaining and adopting the
4516 SLINE PC value if wrong.
4518 * symfile.h (struct complaint, complaint_root, complain,
4519 clear_complaints): Add.
4520 * symfile.c (complain, complaint_root, clear_complaints): Add
4521 facility to deal with non-fatal complaints and to regularize their
4523 (symbol_file_add): Clear complaint counters to allow new complaints.
4524 (initialize_symfile): Add 'set complaints' and 'show complaints'.
4526 * dbxread.c (dbx_symfile_read): Remember the address and size
4527 of the string table for the main symbol file, so we won't read it
4529 (dbx_psymtab_to_symtab): Fix the check for main symbol file,
4530 to avoid reading the string table yet again. Lint.
4531 (throughout): Improve filtered output, including word wrap.
4532 (read_range_type): Improve Bothner's fix to handle other types too.
4534 * utils.c: Improve line wrap implementation. Handle unlimited
4535 width by making chars_per_line unsigned.
4536 (puts_filtered): New, easy, function.
4538 * defs.h (puts_filtered): add.
4540 * mipsread.c (compare_symbols, sort_symtab): Remove these fns,
4541 call the identical sort_symtab_syms() in symfile.c instead.
4543 * expread.y: Suggest the `file' command rather than `symbol-file'.
4545 * command.h (enum var_types): Add zinteger for seroable
4547 * command.c (do_setshow_command): Handle var_zinteger. Restructure
4548 nested if's into a switch.
4550 * breakpoint.c (bpstat_print): If bpstat "print" flag is not set,
4551 we did not stop because of a breakpoint (it must have been for
4552 some other reason, like a "stepi"), so don't print anything.
4554 * symtab.c: Include <sys/types.h> all the time. Now that BFD
4555 doesn't include <sys/types.h>, old SunOS's require it for
4558 Sat Feb 2 10:39:15 1991 Per Bothner (bothner@cs.wisc.edu)
4560 A test port of gdb-3.92.6 to the Sony NEWS.
4563 Don't normally link in remote- or vx stuff.
4564 Some of it doesn't compile, and it wastes space for 99% of the users.
4565 Remove reference to no-longer-used HAVE_VPRINTF.
4566 Fixed BFD_DEP typo to BFD_DIR.
4568 Fix cast in arg to bfd_h_getlong.
4569 Make char *prefix be const.
4570 Fix how certain range types are mapped into builtin unsigned int types.
4572 Remove 2 #includes. They cause errors (on Sony, at least),
4573 and aren't needed (they wern't in earlier versions).
4575 print_address_symbolic should never demangle labels
4576 (since it prints *assembler-level* labels).
4578 [This was superseded by the change to printcmd below.]
4581 Add some "volatile" return types to avoid warnings.
4582 If MISSING_VPRINTF add vprintf function and not just macro
4583 (since vprintf is used in printcmd.c).
4585 Unless __GNUC__, use obstack_grow instead of obstack_ptr_grow.
4586 (The latter isn't grokked by some PCC-based compilers.)
4588 [This change is in abeyance, we prefer to fix obstack_ptr_grow.]
4590 Make chunk size of dont_print_obstack 32*4 instead of default 4096.
4591 * nindy-share/coffstrip.c
4592 Added some forward declarations (otherwise, gcc complains
4593 about implicit extern redefined as static).
4595 Sun Jan 20 02:38:19 1991 John Gilmore (gnu at cygint.cygnus.com)
4597 Changes inspired by Per Bothner:
4598 * printcmd.c (print_address_symbolic): Take additional parameter
4599 specifying whether to demangle.
4600 (print_address): Pass in asm_demangle to control demangling.
4601 (print_address_demangle): New fn, takes explicit arg to control
4603 * utils.c: Add new vars demangle and asm_demangle, and let them
4605 (fputs_demangled): If !demangle, just print the argument.
4606 (fprint_symbol): If !demangle, just print raw symbol.
4607 * valprint.c (val_print): Call print_address_demangle rather than
4608 print_address, to cause demangling to depend on the global
4609 rather than assembler-level demangling setting.
4610 * WHATS.NEW, gdb.texinfo: Document.
4612 * main.c (show_command): Show all settings if no arg.
4613 (initialize_main): Make "info set" the same as naked "show".
4614 * command.c (cmd_show_list): Handle prefix commands in the
4615 list, and print the name of the setting as well as its English
4616 description and value.
4618 Allow gdb functions to specify where a line should wrap if it
4619 exceeds the size of a terminal line. Use it to make the output
4621 * utils.c (set_screen_width_command): New fn, mallocs a buffer
4622 of the right size when screen width changes.
4623 (set_screensize_command, screensize_info): Remove #if 0'd fns.
4624 (wrap_here): New fn, indicates a point in the output where we
4625 should wrap the line rather than just letting it overflow at a
4627 (fputs_filtered): Implement wrapping.
4628 (n_spaces): New fn, returns a pointer to N spaces.
4629 (print_spaces_filtered): Use n_spaces.
4630 * defs.h (n_spaces): Declare.
4631 * stack.c (print_frame_info): Wrap with 4-space indent after
4632 fn name and before filename and line number.
4633 * printcmd.c (print_frame_args): Wrap with 4-space indent
4634 before each argument name is printed.
4635 * valprint.c (value_print): Wrap with no indentation before
4637 (val_print_fields): Wrap with indentation relative to nesting
4638 level before each field name.
4639 (val_print): Wrap with nesting indentation before array elements.
4640 * command.c (do_setshow_command): Avoid extra newlines,
4641 wrap with 4-space indent around values printed, end with period.
4642 * WHATS.NEW, gdb.texinfo, gdb-int.texinfo: Document.
4644 * breakpoint.c (breakpoint_1): Implement addressprint for
4645 "info breakpoints" display. Change file name and line number
4646 format to " at file:nnn" rather than " (file line nnn)".
4647 * gdb.texinfo: Document.
4650 Fri Jan 18 07:21:25 1991 John Gilmore (gnu at cygint.cygnus.com)
4652 Frozen for gdb-3.92.6 release.
4654 README, WHATS.NEW: Update for 3.92.6 release.
4656 tconfig/{altos, i386v, i386v32, m88k, umax}: Eliminate
4657 coffread.o from configs since it is now built by default.
4658 tconfig/{3b1, altosgas, arm, convex, hp300bsd, hp300hpux,
4659 i386v-g, i386v32-g, isi, merlin, news, news1000, np1, pn,
4660 pyramid, symmetry, vax, vxworks68}: Eliminate dbxread.o
4661 from configs since it is now built by default.
4663 Makefile.dist: Update for release 3.92.6. Handle files that
4664 have been moved to ../include, ../getopt, or ../bfd. Add
4665 saber.suppress and tests directory. Add config.status to
4666 the release (it will say "none").
4668 coredep.c: Minor formatting fixes.
4670 These changes were made in early December but only checked in now:
4671 * nindy-share/Onindy.c, nindy-share/coffstrip.c,
4672 nindy-share/nindy.c: lint
4673 * nindy-share/nindy.c (ninStopWhy): Don't byteswap the
4674 register values coming back from the target; we store values
4675 in target byte order everywhere.
4677 Wed Jan 16 19:01:37 1991 John Gilmore (gnu at cygint.cygnus.com)
4679 * am29k-opcode.h, am29k-pinsn.c: Add 29050 opcodes.
4681 * valprint.c (cplus_val_print, val_print_fields): New functions,
4682 which print C++ objects. They conspire to avoid printing a
4683 virtual base class more than once, following all the twists and
4684 turns of C++ virtual base rules.
4685 (val_print): Call the above rather than do it by hand.
4687 * symfile.c (symbol_file_add): Only reset symfile_mtime for main
4688 symbol file, not for added files like shared libs. This really
4689 needs to be generalized to a timestamp per file.
4691 * core.c (cleanup_core): Avoid coredump if no core file.
4693 * config.gdb: Accept -host or -target in place of +host or
4696 * coffread.c (find_linenos): Avoid desupported BFD interface
4697 to line numbers. We still read them manually rather than using
4698 BFD's "generic" features.
4700 * gdbrc.tex, threecol.tex: Add GDB reference card and its
4702 Makefile.dist: Add refcard to OTHERS list for creating tar files.
4704 * Makefile.dist: Eliminate use of $< in explicit targets.
4706 * readline/Makefile: Use $< rather than $*.c, which does not
4707 include the VPATH in GNU Make.
4709 * tconfig/i960-bout, tconfig/i960-coff: These are identical
4710 copies of tconfig/i960, added for global configuration
4711 compatability. All i960 versions can read both coff and b.out.
4713 * tm-88k.h: Fix multiline macro that lacked \'s. Remove
4714 COFF_FORMAT and COFF_CHECK_X_ZEROES since these are now handled
4717 * TODO: Think of more things to do.
4719 Wed Jan 2 19:09:29 1991 John Gilmore (gnu at spiff.cygnus.com)
4721 tconfig/{am29k,i960,sun2*,sun3*,sun4*}: Eliminate config
4722 of sdb versus dbx debug symbols. Add kludge for 68881 80-bit to
4723 64-bit float conversion.
4725 tconfig/sun4, tconfig/sun3, xconfig/sun4, xconfig/sun3: Make
4726 equivalent to sun?os4 so global config works.
4728 Wed Jan 2 18:20:51 1991 John Gilmore (gnu at spiff.cygnus.com)
4730 Fix from Eberhard Mattes <mattes@azu.informatik.uni-stuttgart.de>
4732 * main.c: Only declare linesize once; declare pagesize not at
4733 all, since it is never used.
4734 (main): Clear newly allocated line before it is used.
4736 Fri Dec 28 00:13:42 1990 John Gilmore (gnu at cygint)
4738 Further stabilization for the Intel 960.
4740 * Makefile.dist: Parameterize the location of the "include"
4741 and "bfd" directories, as well as "getopt". Add symfile.c.
4742 Link in both dbxread and coffread. Fix up "make depend" to
4743 rewack the locations of include, bfd, and getopt in its output.
4745 * README: Document moving include files, improve some of
4748 * coffread.c: Move common code out to symfile.c. Change
4749 symbol_file_command style interface to use new *_symfile_init
4750 and *_symfile_read interface under BFD. Use BFD internal
4751 info to locate line table, symbols, etc.
4753 * core.c (core_fetch_registers): Rename to get_core_registers
4754 to avoid confusion with fetch_core_registers.
4755 (register_addr): Move to coredep.c, which is already machine
4756 dependent. This leaves core.c pretty clean of dependencies.
4758 * coredep.c (register_addr): Accept this routine from core.c.
4760 * dbxread.c: Move common code (with coffread.c, etc) into new
4761 symfile.c. Each psymtab now contains a pointer to the
4762 format-dependent function that knows how to read it in. Make
4764 (dbx_psymtab_to_symtab): Renamed from psymtab_to_symtab_2.
4765 (process_one_symbol): Add code to complain about a "compiler bug
4766 we muzzle here", if we actually see it.
4768 * eval.c (evaluate_subexp): Insert missing "break" statements
4769 in code that determines whether a variable is an lvalue in
4770 memory, register, or whatever. I detected this via a compiler
4771 bug in which it *almost* mashed out the whole switch statement.
4773 * gdb-int.texinfo: Add minor sections on configuring gdb for
4774 release, and about the README file.
4776 * infcmd.c (registers_info): Fix formatting somewhat. Still
4777 not as pretty as before, but it handles byte swapping.
4779 * remote-nindy.c: If data cache routines are interrupted while
4780 waiting for the remote end, be sure that any uninitialized cache
4781 blocks are on the free list, not on the valid list!
4783 * symfile.h: Flesh out this header file with all the various
4784 routines and variables that have been merged in from dbxread.c
4785 coffread.c, and symtab.c to symfile.c.
4787 * symfile.c: New file, containing code common to dbxread.c,
4788 coffread.c, and some code from symtab.c. All generic code for
4789 reading symbol files should be in here now.
4790 (unrecord_misc_function): Remove unused function.
4792 * symtab.h: Remove file-reading things to symfile.h.
4794 * symtab.c: Remove file-reading things to symfile.c.
4796 * tm-i960.h: Fix FRAME_CHAIN types; define PRINT_RANDOM_SIGNAL
4797 to decode i960 fault types.
4799 * target.h, remote.c, remote-eb.c, remote-vx.c, remote-nindy.c,
4800 target.c: Change type of the "resume" function from int to void,
4801 since its result was never used.
4803 Sat Dec 22 02:51:40 1990 John Gilmore (gnu at cygint)
4805 * main.c: Replace "stupid" with "caution"; you now "set caution
4808 * printcmd.c (print_scalar_formatted): Fix typo in 'g' format
4810 * infcmd.c (do_registers_info): Call val_print to deal with the
4811 byte order of the registers being printed. FIXME, this makes
4812 the formatting of the output uglier.
4814 * infcmd.c (wait_for_inferior): If PRINT_RANDOM_SIGNAL is
4815 defined, call it for signals the debugger doesn't itself use.
4816 The i960 uses this for more detailed fault information.
4818 * remote.c (remote_open): If arg is null, print help rather than
4821 * sparc-xdep.c (register_valid): Avoid declaring size, since
4822 various modules will think of various sizes depending on the
4823 architecture of their tm-file. FIXME, we need protection against
4824 actually entering one of those modules, which would clobber
4825 storage if not for the target architecture compiled into gdb.
4827 * stack.c (up_command, down_command): Always print the frame
4829 (up_silently_command, down_silently_command): New commands
4832 * i960-pinsn.c (reg), i960-tdep.c: Lint.
4834 * i960-tdep.c (i960_frame_chain_valid): Lookup_symbol now takes
4835 more parameters than it used to.
4837 * findvar.c (registers): Increase slop to 256 bytes, which should
4838 protect us against even most RISC machines with large register
4840 (locate_var_value): Move declaration inside related ifdef.
4842 * remote-nindy.c (): Use TIOCSETN rather than TIOCSETP
4843 throughout, to avoid throwing away buffered input from the board.
4844 (nindy_wait): Supply_register takes addr_of_value, not value.
4845 (i960_print_fault): Renamed from i80960_fault.
4846 (nindy_fetch_registers): Avoid have_regs stuff, just get them.
4847 (nindy_store_registers): Avoid regs_changed stuff, just stuff
4849 (nindy_create_inferior): Don't bother to write PC_REGNUM since
4850 we can set the PC in the call to proceed(). Unpush nindy_ops
4851 before pushing it on top, to avoid message to user. Eliminate
4852 commentary from Unix machines that just misleads here.
4853 (reset_command): Fix error message to suggest target command.
4855 Wed Dec 19 11:03:56 1990 John Gilmore (gnu at cygint)
4857 Release 3.92.5 as frozen.
4859 Stabilize the merged release...with help from lint, Saber C,
4862 Everywhere: Add include files needed to declare return types
4863 of functions called.
4865 * gdb.texinfo: Roland Pesch is documenting gdb, glory be!
4867 * breakpoint.h: Add undeclared breakpoint functions, and some
4868 functions for display handling since I couldn't think of a better
4871 * breakpoint.c (insert_breakpoints): Make code for disabling
4872 shared library bkpts more likely to work. It's used when we
4873 rerun a program and stop before the shared library has been
4875 (breakpoint_cond_eval, bpstat_stop_status): Pass arg as int,
4876 cast from pointer, so it squeezes through catch_errors.
4877 (bpstat_stop_status): Fix logic broken some time ago. We now
4878 always create a bpstat if the stop address matches a breakpoint,
4879 even if we don't stop there -- just like the old code used to do
4880 before I got my fingers into it (sigh).
4881 (breakpoint_1): Print "ignore count" after "stop only if"
4882 condition, since that's how it actually works.
4883 (mention): Handle watchpoints as well as breakpoints.
4884 (watch_command): use set_raw_breakpoint and mention to do most
4885 of the work (and initialize all the fields!). Only pass one
4886 arg to parse_c_expression, since that's all it takes.
4888 * command.c (not_just_help_class_command): Rename arg to args
4889 since we ignore "unused argument" warnings on vars named "args".
4890 inflow.c (child_terminal_info): ditto.
4891 infptrace.c (kill_inferior): ditto
4892 main.c (catch_errors, version_info, quit_command, pwd_command,
4893 source_command, dump_me_command, editing_info,
4894 set_history_size_command, set_history, show_history,
4896 stack.c (locals_info): ditto
4897 target.c (target_files_info): ditto
4898 valprint.c (set_input_radix, set_output_radix): ditto
4900 * core.c: Remove old variables for handling core and exec file
4901 sections (data_start, data_end, stack_start, stack_end,
4902 reg_stack_start, reg_stack_end, reg_stack_offset, text_start,
4903 text_end, exec_data_start, exec_data_end, text_offset,
4904 exec_data_offset, data_offset, stack_offset). They're
4905 superseded the more general build_section_table and
4907 (get_exec_file): Mention the `file' command.
4908 (read_memory_check): Rename to memory_error, and only call it
4909 in the case of an actual error.
4910 (read_memory, write_memory): call memory_error.
4911 (core_fetch_registers): Register section name is ".reg".
4913 coredep.c: Remove a bunch of crud now that all this file does
4914 is pull the registers out of a core file.
4915 (fetch_core_registers): Rewrite to actually work, I hope.
4917 dbxread.c: Use a.out.gnu.h, not system a.out, now.
4918 Replace index() with strchr(). Remove all the pre-BFD macro
4919 definitions for accessing the symbol file.
4920 (struct dbx_symfile_info): Encapsulate the information that
4921 dbx_symfile_init needs to pass to dbx_symfile_read in this
4924 (dbx_new_init, dbx_symfile_init, dbx_symfile_read,
4925 dbx_symfile_discard): Rearrange symbol file reading to divide
4926 the format-specific part from the format-independent part,
4927 leaving the format-independent part such as file name expansion
4928 and opening in symtab.c. This replaces
4929 partial_symbol_file_open and partial_symbol_file_read.
4930 Symbol_file_read, add_file, add_file_target_command,
4931 add_file_addr_command move to symtab.c. Pass an explicit
4932 "mainline" flag for when reading the main symbol table, rather
4933 than relying on the offset address to be zero or nonzero.
4935 (dbx_symfile_read): Don't allow void *'s to be printed as
4937 (SWAP_SYMBOL): Use bfd routines to byte-swap the symbols.
4938 (ADD_PSYMBOL_TO_LIST): Make the "function call rather than
4939 macro" debug version really work.
4940 (read_dbx_symtab): Remove unref'd parameter inclink.
4941 Avoid swapping N_SLINE symbols, for speed.
4942 Merge N_TEXT!N_EXT case with the other external symbol
4943 definitions' case. Add comments.
4944 (start_psymtab): Allocate the symfile name in the psymtab on
4945 the psymbol_obstack, rather than using the caller's storage.
4946 (end_psymtab): Only allocate a dependencies list if there are
4948 (psymtab_to_symtab_2): Use BFD when reopening file to read
4949 its symbols for real.
4950 (read_struct_type): Add FIXME comments where it needs work
4952 (read_huge_number): Add FIXME about overflows.
4953 (read_range_type): Add FIXME about comparing a long to 1<<32.
4955 * coffread.c: Minor changes to move things closer to the new
4956 regime with symtab.c and dbxread.c Major work is still needed
4959 * exec.c (exec_file_command): Remove old variables (see core.c
4961 (xfer_memory): If memory transfer is right at the end of a
4962 section, don't lose.
4964 * findvar.c (get_saved_register): If value is in a real
4965 register, LVAL is lval_register, not lval_memory.
4967 frame.h: Declare print_sel_frame and record_selected_frame.
4969 gdb-int.texinfo: New file, for GDB internals documentation.
4970 Very simple, unformatted doc of cleanups is there for now.
4972 gdbcore.h: Remove obsolete variables that described a.out
4973 section addresses and offsets. (See core.c above.)
4974 Declare fetch_core_registers and registers_fetched.
4976 getopt.c: Declare char *alloca(); even on SPARC.
4978 infcmd.c (run_command): Call target_kill rather than
4980 (step_command, next_command, stepi_command, nexti_command):
4981 Declare from_tty parameter even though we don't use it.
4982 (run_stack_dummy): argument BUFFER is a char array, not
4983 a pointer to REGISTER_TYPE.
4984 (finish_command): using_struct_return needed a value *,
4985 not a struct symbol *.
4987 * infptrace.c (child_xfer_memory): To avoid dependency on
4988 where sections are in memory, try PT_WRITE_D and if that fails,
4989 try PT_WRITE_I. Most Unixes don't care which you use.
4991 * infrun.c (step_resume_break_shadow): Change to array to
4992 match other breakpoint shadow storage.
4993 (clear_proceed_status): Pass address of bpstat to
4994 bpstat_clear, not the bpstat itself.
4995 (child_create_inferior): FIXME comment about if the child
4997 (start_inferior): Remove old function.
4998 (child_open): Use target_kill rather than kill_inferior.
4999 (wait_for_inferior): Ditto.
5000 (insert_step_breakpoint, remote_step_breakpoint): Use
5001 new step_resume_break_shadow.
5003 * inftarg.c (child_wait): If all child processes die,
5004 pretend that the one being waited for exited with signal 42.
5006 * main.c (command_line_input): When scanning for comments,
5007 don't coredump on unclosed quotes.
5008 (quit_command): Use target_kill rther than kill_inferior.
5009 (_initialize_main): Rename class_user from "user" to
5012 * printcmd.c (print_command_1): Initialize "fmt" if no format
5013 is specified by the user.
5014 (print_frame_args): Only add to args_printed if we are
5015 actually fetching args from the stack (avoiding undefined
5017 (_initialize_printcmd): Remove bogus \{ from string.
5019 * remote-eb.c (eb_open): Avoid coredump on no argument.
5021 * remote-nindy.c: Bring out of Intel environment into new
5022 target environment. Remove all conditional compilation on
5023 I80960. Massive hacking throughout.
5024 (nindy_xfer_inferior_memory): New routine stolen from
5026 (nindy_create_inferior): New routine pieced together, probably
5027 not quite working yet.
5028 (nindy_ops): New target_ops struct for nindy.
5030 * remote-vx.c: Use write_memory rather than target_write_memory
5031 to get error checking.
5032 (vx_add_file_command, vx_open): Use symbol_file_add rather than
5034 (vx_create_inferior): Use target_terminal_ours...
5036 * signame.c (_initialize_signame): Always initialize, since
5037 we need the table for things other than psignal.
5039 * solib.c (solib_add): Use symbol_file_add, not add_file.
5040 (solib_address): Return boolean result rather than struct
5041 pointer which nobody else knows the type of.
5043 * sparc-tdep.c, valops.c: Use write_memory rather than
5044 target_write_memory, to get error checking.
5046 * stack.c (locals_info, catch_info, args_info,
5047 get_selected_block, frame_command, up_command): Use
5048 target_has_stack, rather than have_inferior_p or
5051 * sun3-xdep.c (fetch_core_registers): Rewrite for new BFD regime.
5053 * symfile.h: New file, defining the interface between the
5054 generic and object-file-specific symbol reading code.
5056 * symtab.c: Move generic symbol-reading interface to symtab.c,
5057 from dbxread.c, coffread.c, mipsread.c, etc. Add symtab_fns
5058 table to map BFD targets to symbol-reading modules in GDB.
5059 Change index to strchr.
5060 (lookup_struct_elt_type): Use error() rather than hand-made
5061 simulations thereof.
5062 (lookup_partial_symbol): Speedup slightly when length == 0.
5063 (symbol_file_add): New function.
5064 (symbol_file_command): Call it.
5065 (symfile_open, symfile_init): New function.
5066 (add_file_target_command, add_file_addr_command): moved from
5069 * target.c (target_command): use target_kill.
5071 * target.h (target_files_info): Don't declare, never called
5074 * tm-sun2.h, tm-sun3.h (STACK_END_ADDR): Use system include
5075 files to determine stack end address.
5077 * valarith.c (value_x_binop, value_x_unop): Change error message
5078 to be more useful. Pass proper argument to value_struct_elt.
5080 * valops.c (value_assign): FIXME comment that long long
5081 bitfields will break here.
5083 * Makefile.dist: Add symfile.h, remote-nindy.c, remote-eb.c.
5084 Update `make saber_gdb' to work better.
5086 * TODO: A woman's work is never done.
5088 * cplus-dem.c, environ.c, inferior.h, infrun.c, inftarg.c,
5089 main.c, obstack.c, printcmd.c, remote-eb.c, remote-nindy.c,
5090 remote-vx.c, remote.c, solib.c, source.c, sparc-pinsn.c,
5091 sparc-tdep.c, sparc-xdep.c, symmisc.c, symtab.c, symtab.h
5092 target.c, terminal.h, tm-sparc.h, tm-sunos.h, utils.c,
5093 valops.c, valprint.c, exec.c: Lint.
5096 Wed Dec 12 23:44:15 1990 John Gilmore (gnu at cygnus.com)
5098 Continuing Intel 960 port merge of GDB.
5100 * Makefile.dist: Merge i960 "nindy-share" files. Rename
5101 malloc.h to gmalloc.h to avoid name conflicts in /usr/include.
5102 Don't ship gdb.dvi in tar file. Link gdb with init.o, not init.c.
5103 Wack over "make depend" so it handles files in subdirectories
5104 vx-share, nindy-share, bfd, and in the current directory.
5106 * blockframe.c (get_prev_frame_info): Remove fatal error
5107 if stack not defined.
5109 * core.c (core_open, core_detach): New functions that handle
5110 the old "core-file" command as "target core" and "detach" instead.
5111 (core_file_command): Call them.
5112 (core_xfer_memory): Use common routine xfer_memory.
5114 * dbxread.c: Include a.out.gnu.h, not system a.out.h.
5115 dbxread now uses bfd for everything but symbol reading itself.
5116 BFD internals are used to drag out the relevant file offsets.
5117 (partial_symbol_file_open): Change args all around for BFD.
5119 * symtab.c: Rename "value" to "val" everywhere, so we can
5121 (symbol_file_command): New command, moved from dbxread.c
5122 and coffread.c. It uses BFD to read the file, then vectors
5123 based on its type, to dbx or coff symbol readers.
5124 * symtab.h: Extern a few vars for symbol_file_command.
5126 * target.h: Breakpoint takes a char * save area, not a char **.
5128 * valprint.c (val_print): When unpacking bitfields, offset
5129 the address in gdb of the value, if it is declared with a shorter
5130 type. Remove the last "runtime kludge test" of host byte order.
5132 * utils.c: Remove old my_bfd_read routine.
5134 * stack.c (frame_info): Use target_has_stack. Print program counter
5135 register's actual name rather than "pc", since it's called the
5136 "ip" (instruction pointer) on the i960 (sigh).
5138 * target.c (target_command): Add command for selecting a target
5139 type and calling its open routine. This is used for initiating
5140 communication with a particular target, in a generic way.
5142 * tm-i960.h: Update for modern gdb. Remove semicolons from
5143 various macros. Handle reading struct return convention, and
5144 error-out attempts to return structs with the "return" command.
5145 Be sure gdb doesn't think we know how to call functions in the
5148 * i960-tdep.c: Rename FRAME_CHAIN_VALID and FRAME_FIND_SAVED_REGS
5149 to i960_xxx in lower case.
5150 (arg_address): Circumvent errors due to LOC_ARG_BLOCK
5151 not being defined yet.
5153 * remote.c (remote_open): Call start_remote to initialize
5154 wait_for_inferior during open.
5155 (remote_xfer_inferior_memory): Return length written rather
5158 * remote-vx.c (target_command -> vx_open): Use new generic
5160 * remote-eb.c, inftarg.c, exec.c: ditto.
5162 * infrun.c: Fix comments.
5163 (attach_program -> child_open): Use new generic target command.
5164 (wait_for_inferior): Clear saved register values before target_wait,
5165 so target_wait can set some of them if convenient.
5167 * infptrace.c (fetch_inferior_registers, store_inferior_registers):
5168 Return success indicator, not void.
5169 (child_xfer_memory): Avoid fetching initial word if we'll
5170 overwrite it anyway.
5172 * infcmd.c (attach_command): Use new generic target open routine.
5173 (_initialize_infcmd): Update doc on attach and detach commands.
5174 (do_registers_info): Merge in a byte-order problem as a FIXME
5177 * findvar.c (find_saved_register): Avoid problem in current frame.
5178 (read_relative_register): Ditto.
5179 (write_register): Convert byte order on the way out.
5181 * exec.c (file_command): Add.
5182 (add_to_section_table, exec_command): Use new bfd_map_over_sections.
5183 (xfer_memory): Common function between core_xfer_memory and
5185 (exec_xfer_memory): Use it.
5187 * pn-opcode.h: Document that a "PN" is a Gould PowerNode.
5189 * breakpoint.c, breakpoint.h, symtab.h, value.h, frame.h, utils.c,
5190 valops.c, stack.c, target.c, sparc-xdep.c, source.c, printcmd.c,
5191 infcmd.c, i960-pinsn.c, eval.c, defs.h: lint and gcc -Wall.
5193 Sun Dec 2 16:45:06 1990 John Gilmore (gnu at cygnus.com)
5195 Merge Intel 960 port of gdb, continuing...
5197 * dbxread.c (partial_symbol_file_open, partial_symbol_file_read,
5198 symbol_file_command): Pass from_tty arg to hush 'em up.
5200 * coffread.c (symbol_file_command): Avoid output if from_tty != 1.
5201 Add magic numbers for 960 COFF format.
5203 Fri Nov 30 09:18:20 1990 John Gilmore (gnu at cygnus.com)
5205 Merge Intel 960 port of gdb, from Intel "1.2" release.
5207 CHANGE_LOG entries from their port, which was based on

5211 Remove temp file if download is interrupted.
5213 Wed Aug 1 09:08:33 PDT 1990
5214 Now uses binary protocol to talk to NINDY.
5215 Old hex protocol (NINDY 2.13 and older) supported with -O switch.
5216 Times out after 5 seconds when trying to talk to NINDY.
5218 Tue May 29 12:54:49 PDT 1990
5219 Added variable baud rate (-b switch).
5220 Source code reorganization.
5222 Thu Apr 26 11:09:55 PDT 1990
5223 More cleanup of batch mode; specifically, execute "-s", "-e", and
5224 "-se" switches as soon as they are encountered on the invocation line.
5226 Fri Apr 20 13:47:15 PDT 1990
5229 Thu Apr 19 09:54:28 PDT 1990
5230 Add 'reset' command.
5232 Wed Apr 18 09:48:07 PDT 1990
5233 After opening remote tty, wait for 1 second to go by without input
5234 from it before trying to talk to NINDY (fixes problems with the
5235 Heurikon HK80/V960E).
5237 Mon Apr 4 16:33:05 PDT 1990
5238 Some output was not being suppressed in 'batch' mode.
5240 Thu Mar 22 15:31:11 PST 1990
5241 Ask user if old symbol table should be deleted when new file is
5244 Allow user to run a program downloaded before gdb960 was brought up.
5246 Correct "exec-file" help message for i80960 context.
5248 Correct bug in calculating user space address: could occasionally
5249 corrupt user program.
5251 Make sure to zero low-order bits in rip's because of bug in 960CA
5252 A-step part: could cause operation faults when "next"ing across
5255 Correct bug that made it impossible to get source line numbers for
5256 code loaded at addresses higher than 0x7fffffff.
5258 Wed Jan 10 12:43:22 PST 1990
5259 Open remote tty for exclusive use.
5261 Fri Jan 5 12:14:42 PST 1990
5262 Correct disassembly (CA manual was right after all):
5263 opcode for sysctl is 0x659
5265 Mon Oct 23 12:03:04 PDT 1989
5266 Use G960BASE and G960BIN environment variables to find 'sx' utility.
5268 Mon Oct 16 14:15:09 PDT 1989
5269 "sfr0"-"sfr31" should have been named "sf0"-"sf31"
5271 Mon Oct 2 15:56:31 PDT 1989
5273 Added 960CA disassembly support.
5275 To simplify maintenance:
5276 - eliminated use of symblic links on pinsn.c: use i960-pinsn.c
5278 - eliminated opcode.h: incorporates tables into i960-pinsn.c
5279 - moved 960-specific routines from i960-pinsn.c to i960-md.c
5280 - made disassembly interface identical to that in gdmp960.
5284 Wed Nov 28 21:32:48 1990 John Gilmore (gnu at cygint)
5286 * target.h: Allow targets to stack. Add target_has_memory,
5287 _registers, etc. Restructure memory access and "info files"
5288 to walk the target stack.
5289 * exec.c, core.c, inftarg.c, remote.c, remote-vx.c, remote-eb.c,
5290 target.c: Change tables to match target.h.

5296 * remote-vx.c: New memory regime, new info files. Now use
5297 separate targets for VxWorks attachment to machine, and
5298 actually running a process under VxWorks, since one has
5299 stack & execution & regs and the other doesn't.
5300 * remote.c: New memory regime, new info files.
5301 * sparc-xdep.c (fetch_core-registers): New memory regime.
5302 * target.c: New routines and support for stacked targets,
5303 new memory regime, new info files regime.

5332 since been deleted, such as temporary breakpoints.
5333 infcmd.c (program_info): ditto.
5335 * core.c (core_file_command): Display the frame where the core
5340 * remote-vx.c (target_command): Merge in target command from
5341 targ-vx.c. A few other cleanups.
5343 * TODO, Projects: Lots more stuff to do...
5345 Fri Nov 23 18:15:38 1990 John Gilmore (gnu at cygint)
5347 Massive changes to wall off the remote-debugging interface
5348 behind a function vector. The port to handle VxWorks targets
5349 is also part of this.
5351 All files: Replace references to renamed functions,
5352 remove references to remote_debugging, remove references to
5353 have_include_file, have_core_file in favor of target_has_stack,
5354 target_has_memory, etc.
5356 * Modularize the breakpoint interface.
5357 breakpoint.h (BREAKPOINT_MAX): New define sets max length of
5358 a breakpoint instruction.
5359 breakpoint.c: struct breakpoint's shadow_contents now sized as
5361 (insert_breakpoints): Vector to target to install breakpoints.
5362 (remove_breakpoints): Vector to target here too.
5363 Remove REMOTE_SA_SPARC kludges and other remote_debugging.
5364 sparc-tdep.c (single_step): Use new breakpoint interface for
5365 the single-step breakpoints.
5366 mem-break.c (memory_insert_breakpoint, memory_remove_breakpoint):
5367 New file, contains routines to insert and remove breakpoints by
5368 reading out the old contents and later replacing them. This is
5369 how ptrace breakpoints work, and many remote systems as well.
5371 * tm-vxworks68.h: New config file, overrides a few things for
5372 Wind River's preferences.
5374 * target.h: New file, for transfer vector used to talk to the
5375 inferior (child, attached, core, exec, remote, etc). All accesses
5376 to the thing being debugged should come through these vectors.
5377 target.c: New file, routines to handle transfer vector.
5378 (various files): Add transfer vectors XXX_ops for the various
5379 targets and pseudo-targets (core files, etc) we support.
5381 * breakpoint.c (bpstat_stop_status): Further explorations of
5382 watchpoints and why things don't work all the time.
5383 (bpstat_alloc): New fn to allocate a bpstat and chain it.
5385 * config.gdb: Only add "source ${srcdir}/.gdbinit" to
5386 the local gdbinit if it doesn't already have it.
5388 * core.c (core_ops): add and install.
5389 Allow core debugging without exec file.
5391 * dbxread.c (free_and_init_header_files): Merge two fns.
5392 (end_symtab): Free named symbol table when a new version comes in.
5393 (read_dbx_symtab): Relocate all kinds of symbols with base
5394 address. First step toward handling different text, data, bss
5396 (add_file_addr_command): Renamed add_file_command.
5397 (add_file_command): Vector to remote handler.
5398 Add "load" as an alias for "add-file" command.
5400 * defs.h: Allow "volatile" to be used in non-ANSI; use it for
5401 non-returning functions.
5403 * exec.c: Add exec_ops, and push it as a target when an exec
5406 * infcmd.c (run_command): Pass executable file name and arg list
5407 separately when starting an inferior. Permit "run" when no exec
5408 file is specified, for VxWorks.
5409 (detach_command): Move to child_detach in inftarg.c.
5411 * inftarg.c: New file. Unix-child-specific routines, and the
5412 child_ops structure.
5414 * inferior.h (registers): Export "registers" as the way for
5415 target dependent register handlers to find gdb's local copy of
5416 the registers. Rename "stop_after_attach" to "stop_soon_quietly"
5417 since it is now used by places that want wait_for_inferior to
5418 handle the grunge but want to see every trap from the inferior.
5420 * inflow.c (create_inferior): Pull out, and merge into infrun.c.
5421 Eliminate remote_debugging hooks in terminal handling.
5423 * infrun.c: Replace start_inferior with child_create_inferior.
5424 Move all the hair of Unix shells and ptrace idiosyncracies into
5425 child_create_inferior, so remote handlers don't have to deal.
5426 Remove running_in_shell. Rename stop_after_attach to
5427 stop_soon_quietly, and use it in a few other places where we want
5428 to just call wait_for_inferior and get control back on the first
5429 trap. trap_expected now never takes a value > 1.
5430 (init_wait_for_inferior): Initialize static vars when a new
5433 main.c (gdbinit): Add new hook for .gdbinit file name, let
5434 it be overridden by config files as GDBINIT_FILENAME.
5435 (DEFAULT_PROMPT): Add new hook for overriding (gdb) prompt.
5436 Both of these are used for VxWorks gdb.
5438 mcheck.c: rename include file "gmalloc.c" to avoid problems
5439 with system include file "malloc.c".
5441 param-no-tm.h: New include file, same as param.h but does not
5442 include the default "tm.h" file. This is used in files where
5443 the target is known, e.g. remote-eb.c or sparc-xdep.c.
5445 param.h: Now just a shell that includes tm.h and param-no-tm.h.
5447 remote-vx.c: New file, VxWorks remote debugging support. Uses
5448 RPC routines that are shared with the target system, in directory
5451 remote.c: Vectorize remote interface.
5453 source.c: Globalize source_path, and make an alias "l" for "list"
5454 since we now have the "load" command.
5456 sparc-xdep.c: Use new param-no-tm.h.
5458 symmisc.c (free_named_symtab): Add new function from Wind River.
5459 However, ifdef it out for now while we think about what it should
5462 tm-sun3.h, xm-sparc.h, xm-sun3.h, xm-symmetry.h: Move
5464 the xm- file, and change its name to CHILD_PREPARE_TO_STORE, since
5465 non-Unix-children handle this with their own code in the target
5468 Makefile.dist: Roll version to 3.92.3. Add vx-share stuff to
5469 source and target lists. Add vx-share to default list of include
5470 directories. Add new files to src and target lists: mem-break,
5471 target, inftarg, remote-eb, remote-vx, targ-vx. Be sure the
5472 ${srcdir} versions of munch and createtags are used.
5474 * valops.c (find_function_addr): Split out of call_function.
5475 (call_function_by_hand): Rename call_function; this function
5476 calls functions in the target by laboriously patching the target
5477 word-by-word with the right stack, args, regs, etc.
5480 Mon Nov 5 17:29:10 1990 John Gilmore (gnu at cygint)
5482 Handle AMD 29000 a bit better.
5484 * remote-eb.c (readchar): Mask received char log to make it readable.
5485 (remote_start): Pass arguments down to executing program.
5486 Make startaddr unsigned.
5487 infrun.c (start_inferior): Accept args, pass them to
5489 infcmd.c (run_command): Pass args down to start_inferior.
5491 * tconfig/am29k-aout, tconfig/am29k-coff: New files specifying
5492 the target object file format.
5493 tm-29k.h: Pay heed to COFF_ENCAPSULATE.
5495 * am29k-pinsn.c (print_insn): Print 0x on hex numbers in disassembly.
5496 am29k-tdep.c (examine_prologue): Better checking of function prefixes.
5498 Sun Oct 7 18:20:45 1990 John Gilmore (gnu at cygint)
5500 * Makefile.dist (VERSION): Roll version to 3.91.9 and freeze.
5501 * TODO: We did a few things, we have more to do though.
5503 * xm-sparc.h (CLEAR_DEFERRED_STORES): Define.
5504 * inflow.c (inferior_died): Clear deferred stores.
5506 * Debug problems with dummy frames and calls to the inferior.
5507 * tm-sparc.h (PUSH_DUMMY_FRAME, POP_FRAME): Move to sparc-tdep.c.
5508 * sparc-tdep.c (do_restore_insn): Simplify.
5509 (sparc_frame_find_saved_regs): Simplify and fix what we find.
5510 (sparc_push_dummy_frame): Simplify and fix what we push.
5511 (sparc_pop_frame): Slightly more hair here, deciding whether
5512 we are restoring a saved PC or returning to a return address in %i7.
5513 * sparc-xdep.c (read_inferior_registers): Debug if valid reg is read.
5515 * utils.c (xmalloc, xrealloc): Return type depends on __STDC__.
5516 * symtab.h (xmalloc): ditto, for obstack_chunk_alloc.
5517 * obstack.h (chunkfun): ditto.
5518 * defs.h (xmalloc, xrealloc): ditto
5520 * utils.c (quit): Grab the terminal from the child if necessary.
5522 * inflow.c (term_status_command): Rename to term_info, change
5525 * sparc-pinsn.c (print_insn): Disassembly prefers real instructions.
5526 (is_delayed_branch): Speed up.
5527 * sparc-opcode.h: Add ALIAS bit to aliases. Fix up opcode tables.
5528 Still missing some float ops, and needs testing.
5530 * Support for input and output radixes other than base 10
5531 * defs.h (input_radix, output_radix): Declare.
5532 * expread.y (yyparse, parse_number): Handle changes of input
5533 radix, and ambiguous names-or-numbers in radixes >10.
5534 * printcmd.c (print_scalar_formatted): Print formatted hex
5535 numbers in varying column widths.
5536 * valprint.c (val_print): Use output_format to print scalar ints.
5537 (set_input_radix, set_output_radix, set_radix): Create.
5538 (set_output_radix): Set output_format from output_radix.
5539 (_initialize_valprint): add `set radix' but leave the others off.
5541 * main.c (execute_command): Let stupid questions be turned off.
5542 (_initialize_main): Handle "set stupidity", etc.
5544 * main.c, inflow.c, inferior.h, frame.h, command.c, defs.h,
5545 sparc-pinsn.c, sparc-xdep.c, value.h, valops.c, values.c: Lint.
5547 Tue Oct 2 11:20:02 1990 John Gilmore (gnu at cygint)
5549 * TODO, Makefile.dist, ChangeLog: Freeze for 3.91.8 release.
5550 bfd stuff is still screwed up, but with some manual work, it
5553 * breakpoint.c (bpstat_do_actions): Start over if a command
5554 proceeds the inferior, since the inferior will have stopped and
5555 will need to have its new stop-actions taken care of.
5557 * dbxread.c (read_struct_type): Expression gives Sun3 4.0.3
5558 compiler fits, simplify it.
5560 * gdb.texinfo (directory command): Doc new dir command.
5561 source.c (directory_command): "dir" now puts things on the front
5562 of the path, moves dups up front, and handles multiple names
5563 on the command line, inserting each one in order. It also
5564 blows away cached line and full_filename info.
5566 * stack.c (backtrace_command): Skip "more stack frames follow"
5569 * Change #ifndef HAVE_VPRINTF to #define MISSING_VPRINTF in
5570 xm-convex.h, xm-hp300bsd.h, xm-isi.h, xm-merlin.h, xm-news.h,
5571 xm-np1.h, xm-pn.h, xm-pyr.h, xm-symmetry.h, xm-umax.h, xm-vax.h.
5572 The only odd one was Gould NP1, which had defined vprintf to
5575 * Merge Ted Goldstein <tedg@Eng.sun.com>'s changes for epoch.
5576 printcmd.c (print_command_1): Pass 'inspect' flag down as a global
5577 variable, inspect_it.
5578 valprint.c (print_string, val_print): Use the global inspect_it
5579 to indicate whether to print in Epoch style or normal style.
5581 Mon Oct 1 23:55:26 1990 John Gilmore (gnu at cygint)
5583 * printcmd.c (call_command): add an alias for the "print" command
5584 which runs expressions and doesn't print the result if void.
5585 (print_command_1): implement it.
5587 * command.c: Remove #if 0'd code. Initialize all the fields
5588 in add_cmd (). Rename do_nothing_command to
5589 not_just_help_class_command, and make it externally visible.
5590 command.h: add user_commands to struct.
5591 * main.c (define_command): Don't overload c->function with a char
5592 string as well as a function pointer.
5594 * eval.c (evaluate_subexp): Reinstall tiemann changes to
5595 calling convention of value_struct_elt () that got dropped in
5598 * tm-sparc.h (FRAME_FIND_SAVED_REGS): move to sparc-xdep.c.
5599 sparc-tdep.c (sparc_frame_find_saved_regs): ditto.
5601 * tm-sparc.h (POP_FRAME): replace some constants with defines.
5603 * sparc-xdep.c (store_inferior_registers): defer stores to regs
5604 until a good time (e.g. when we are about to run the child),
5605 saving ptrace calls.
5606 * infrun.c (proceed): handle DO_DEFERRED_STORES.
5607 * tm-sparc.h: define DO_DEFERRED_STORES.
5609 * sparc-xdep.c (store_inferior_registers): when storing float
5610 registers, don't store stack regs too. When storing the SP,
5611 however, DO store the stack regs too. This fixes a bug in which
5612 the dummy frame is not recognized when a call_function finishes,
5613 because its frame pointer (in the stack regs) was never
5615 (read_inferior_registers): Mark WIM and TBR and FPS and CPS valid
5616 even though we don't know how to read them from an inferior.
5617 valops.c (call_function): Comment about storing SP.
5619 * infrun.c (save_inferior_status): Save away the original bpstat
5620 chain so it can be restored later. Install the copied version for
5621 use by whoever saved the status. It will be blow away by
5622 restore_inferior_status, and the original chain restored. This is
5623 important for people who have pointers into the original.
5625 * breakpoint.c, command.h, copying.awk, dbxread.c, defs.h,
5626 findvar.c, frame.h, obstack.h, obstack.c, inflow.c, value.h,
5627 main.c, printcmd.c, sparc-tdep.c, symtab.c, valprint.c: lint
5630 Fri Sep 28 20:32:46 1990 John Gilmore (gnu at cygnus.com)
5632 * Makefile.dist: Roll version to 3.91.8. Add bfd.h and bfdconfig.h
5633 temporarily to the makefile. Add am29k-opcode.h and WHATS.NEW.
5634 Add stuff.c and kdb-start.c to the OTHERS list for tar files.
5636 Fri Sep 28 19:12:12 1990 John Gilmore (gnu at cygint)
5638 * Merge Mike Tiemann's multiple inheritance changes from Sun.
5639 Store the baseclasses in a type struct starting from array element
5640 0 rather than from the unusual array element 1.
5642 dbxread.c: the above.
5643 (virtual_context): Add
5644 Read new debug information about which virtual function table
5645 a virtual function is from, and store it in fn_field.fcontext.
5647 symtab.h: Add fcontextt. Fix baseclass indices. Typo in
5648 TYPE_FN_FIELD_STATIC_P.
5650 symtab.c: the above.
5651 valops.c: the above. Handle pointer casts of object *'s.
5652 (search_struct_method): Add.
5653 (value_struct_elt): First arg is now a pointer to a value, and is
5656 valprint.c: the above.
5657 values.c (value_virtual_fn_field): Add type arg. Handle
5658 offsetting to the proper object when calling virtual fns.
5660 (baseclass_addr): Add valuep arg.
5662 * README: Document the current state of BFD config (missing).
5663 * TODO, ChangeLog, Makefile.dist: Roll version.
5664 * WHATS.NEW: Add summary of changes since 3.5.
5666 Thu Sep 27 16:23:12 1990 John Gilmore (gnu at cygint)
5668 * dbxread.c (read_struct_type): Clear bit vectors whenever
5670 symtab.c (B_CLRALL): define.
5672 * tm-sparc.h (STORE_RETURN_VALUE): Avoid clobbering types by
5673 using == rather than =. Huh... This fixes the dreaded problem
5674 wherein builtin_type_int becomes TYPE_CODE_FLT.
5676 * core.c (info_files): Show the inferior pid.
5678 * config.gdb: Avoid putting "dir" command into .gdbinit. GDB
5679 already knows how to look in the source directory.
5681 * Remove psymtab hair from many places. Remove duplicated code
5682 for searching symbol tables. Hide psymtabs from most places.
5683 Make it fast to get from a psymtab to its symtab.
5685 blockframe.c (blockvector_for_pc): Remove psymtab hair.
5686 coffread.c (psymtab_to_symtab): Rename to psymtab_to_symtab2.
5687 mipsread.c (psymtab_to_symtab): Rename to psymtab_to_symtab2.
5688 dbxread.c: export psymtab_to_symtab, make it work if called N times.
5689 (psymtab_to_symtab): Rename to psymtab_to_symtab2. Initialize
5690 new symtab completely. New psymtabs get symtab pointer
5691 initialized to zero. Remove MI warning printf.
5692 symtab.h: Comments. Add psymtab to symtab pointer.
5693 (PSYMTAB_TO_SYMTAB): New macro.
5694 symtab.c: use PSYMTAB_TO_SYMTAB. Add psymtab_to_symtab and export it.
5695 source.c: use PSYMTAB_TO_SYMTAB. Remove symtab version and
5697 stack.c (backtrace_command): Avoid pre-pass to read symbols, if
5699 (print_frame_info): Avoid special-casing symbols that have not yet
5702 * source.c (open_source_file): Quick path if we have already
5703 located the source file by its full name.
5705 * symtab.c (lookup_symbol): Use find_pc_symtab rather than
5706 find_pc_psymtab. When a name is found in the misc function
5707 vector, search the symbol table for its mangled name, not the
5708 name that the user typed.
5710 * bfd.h: Fix missing comment terminators, make #endifs match.
5712 * valarith.c (value_less): Handle unsigned int comparisons.
5713 Add FIXME about pointer compares, which assume host and target
5714 pointers are the same.
5716 * command.c (do_nothing_command): lint
5717 dbxread.c: lint. Remove sort_syms. Document C++ visibility info,
5718 fix comments on debug symbol format for visibility. Actually set
5719 visibility of symbols.
5720 main.c (echo_command): lint; use <readline/history.h>.
5721 tm-sparc.h (FRAME_FIND_SAVED_REGS): lint
5722 obstack.h (_obstack_blank): Rearrange pointer math to avoid
5723 pointing past end of allocated memory; saber complains.
5724 obstack.h: Declare the external functions that we use.
5725 valarith.h: use <string.h>
5726 solib.c (solib_add): lint.
5728 Fri Sep 21 17:05:19 1990 John Gilmore (gnu at cygint)
5730 * main.c (initialize_main): Default info_verbose to off, now that
5731 symbol reading is fast.
5732 (quit_command): Avoid clobbering exec_bfd while quitting.
5734 * Initial BFD (binary file diddling library) merger:
5735 coffread.c: Change AOUTHDR to struct exe_hdr.
5737 core.c: initialize initialized data at compile time.
5738 (core_file_command): Move from coredep.c, convert to bfd.
5739 (xfer_core_file): Convert to bfd.
5740 exec.c (exec_file_command): use bfd routines.
5742 mips-tdep.c: Remove exec_file_command and friends.
5745 * coredep.c: (fetch_core_registers) Convert core_file_command to
5746 fetch_core_registers.
5747 mips-xdep.c, sparc-xdep.c, sun3-xdep.c: ditto.
5749 * utils.c: (error): Bogus crap, FIXME, to print bfd errors.
5750 (my_bfd_read): More bogosity, which I don't think we call.
5751 (program_name): Remove this atrocity asap!
5753 Wed Sep 19 13:36:41 1990 John Gilmore (gnu at cygint)
5756 values.c: allocate_repeat_value was not clearing the
5757 optimized_out field.
5758 (value_static_field): minor stylistic fix (wrong macro was used).
5759 valops.c (value_struct_elt_for_address): didn't work for C++
5762 * signame.c (_initialize_signame): Initialize signal names once.
5764 * breakpoint.h, command.c, copying.awk, defs.h, environ.c,
5765 exec.c, frame.h, infcmd.c, inferior.h, main.c, munch, sun3-xdep.c,
5766 symtab.h, tm-29k.h, valprint.c, value.h, values.c: Lint.
5768 * remote-eb.c: Support user-settable baud rates on the serial port.
5770 * tm-sun3.h (PREPARE_TO_STORE): fix typo.
5772 Fri Sep 14 13:28:29 1990 John Gilmore (gnu at cygint)
5774 * tconfig/sun3os4: Remove warning about native assembler,
5775 since it also occurs in the xconfig file.
5777 * findvar.c (registers): Allocate some slop after `registers'
5778 to prevent stray accesses from trashing the next variable.
5780 * tm-68k.h (REGISTER_BYTES): Allocate the right number of bytes
5781 on the sun-3, by changing the #ifdef from `sun3' (which is not
5782 defined by cc) to `sun'. Symptom was trashed builtin_type_XXX
5783 vars, which happened to follow `registers' in the executable.
5785 * readline/history.c (history_search): Heed gcc-2's advice
5786 and parenthesize && inside ||).
5788 * am29k-opcode.h, am29k-pinsn.c, am29k-tdep.c, remote-eb.c,
5789 tm-29k.c: Insert FSF copyright headers.
5791 * remote-eb.c: Better comments.
5793 * Makefile.dist: Update to 3.91.6.
5794 * TODO: note PREPARE_TO_STORE problem.
5796 Thu Sep 13 09:52:33 1990 Jim Kingdon (kingdon at cygint)
5798 * stack.c (frame_info): Only use FRAME_FIND_SAVED_REGS if defined.
5800 * remote.c: Wrap the whole file in #if !defined (SPECIAL_REMOTE).
5802 * infrun.c (wait_for_inferior, at end): Don't set up
5803 prev_* if the inferior no longer exists.
5805 * inferior.h (CALL_DUMMY_LOCATION): New macro, to replace
5806 CANNOT_EXECUTE_STACK.
5807 valops.c (call_function): Use it.
5809 * tm-convex.h: Add CALL_DUMMY_LENGTH for use by PC_IN_CALL_DUMMY.
5811 * inferior.h (PC_IN_CALL_DUMMY): New macro.
5812 infrun.c (wait_for_inferior, 2 places): Use it.
5814 * values.c (value_being_returned): Only use
5815 EXTRACT_STRUCT_VALUE_ADDRESS if defined.
5817 * Move PREPARE_TO_STORE from xm-sun3.h to tm-sun3.h to do the
5818 right thing for remote-eb.c.
5820 * sun3-xdep.c: Remove extraneous call to remote_store_registers.
5821 * sun386-xdep.c, hp300hpux-xdep.c, sparc-xdep.c: Ditto.
5823 * blockframe.c: Put get_frame_saved_regs inside #if !defined
5824 (FRAME_FIND_SAVED_REGS).
5826 * findvar.c ({fetch,store}_registers): Check for
5827 REMOTE_{FETCH_STORE}_REGISTER macro.
5829 * findvar.c (get_saved_register): Add argument lval and
5830 change meaning of argument addr.
5831 findvar.c: Change calls to get_saved_register to reflect
5832 new calling convention.
5833 valops.c (value_assign): Use get_saved_register instead of
5834 find_saved_register.
5836 Sun Sep 2 12:40:20 1990 Jim Kingdon (kingdon at cygint.cygnus.com)
5838 * coffread.c (read_one_sym): Make temp_aux an AUXENT, not
5839 an (uninitialized) pointer to one. Use "&" when passing it
5842 Fri Aug 31 22:57:54 1990 Jim Kingdon (kingdon at cygint.cygnus.com)
5844 * coffread.c (getfilename): Use DGUX x_offset and x_name if
5847 * coffread.c (symbol_file_command): Put semicolon after
5849 Put safe_to_init_tdesc_context in #if defined (TDESC).
5850 Put #ifdef TDESCs in 1st column for non-ANSI cpp's.
5851 coffread.c: #include <sys/stat.h>.
5852 (read_coff_symtab): Typo: in_source_files -> in_source_file.
5853 Add missing ')' in check for "lc%" and friends. Remove
5855 Declare read_one_sym() at top of file.
5856 (read_file_hdr): Put in extra #ifdefs so MC68MAGIC and
5857 MC68WRMAGIC can have the same value without causing a duplicate
5860 Thu Sep 13 15:55:36 1990 John Gilmore (gnu at cygint)
5862 * Allow a Makefile to be built without building the
5863 tm and xm file links that screw up builds in subdirectories.
5864 This is done with `config.gdb none', then you can do things
5865 like `make gdb.tar.Z'.
5866 * tconfig/none: Config file for no target system
5867 * xconfig/none: Config file for no host system
5868 * config.gdb: If no TM or XM files are called out by the
5869 host or target file, don't make links for them.
5871 * cplus-dem.c: Add documentation.
5873 * dbxread.c (read_ofile_symtab): Turn a fatal error into a
5874 simple error, so the user's gdb doesn't crash due to some object
5875 file problem (e.g. somebody is rebuilding the file out from under
5878 * printcmd.c (print_address_symbolic): demangle the symbol.
5880 * Makefile.dist (OTHERS): Remove tdesc-lib because it has
5881 Motorola copyrights in it. Make "make gdb.tar.Z" work.
5882 (alldeps.mak): sort and uniq all results from this; duplicates
5883 hose gdb.tar.Z link building. Remove RCS files from
5884 tconfig and xconfig. Add config files for sun386. Add
5885 a few odd files to OTHERS and HFILES.
5887 Mon Sep 10 21:20:24 1990 John Gilmore (gnu at cygint)
5889 * Makefile.dist: Pull solib.c to tconfig/sun?os4.
5890 Roll version number to 3.91.5. Make lint work in bindir.
5892 * README: Document cross-debugging and new file structure.
5894 * blockframe.c: Lint. Include "value.h" to declare read_register.
5895 (find_pc_partial_function): remove duplicate line.
5897 * command.h: Lint. Declare error_no_arg and dont_repeat.
5899 * tm-news.h: Remove inadvertently duplicated stuff.
5901 * mipsread.c: Remove cache_pc_function stuff, now done cleanly.
5902 Clean up usage of misc_function_type. Declare some CORE_ADDRs.
5904 * config.gdb: Allow `config.gdb host target' form. Clean
5905 up previous change that printed bogus messages when you just said
5908 * core.c: #include "command.h" for lint.
5911 * main.c: Remove some casts of enums. Lint.
5918 * printcmd.c (initialize_printcmd): Fix thinko in inspect cmd.
5920 * sparc-tdep.c (isannulled): Take instruction as parameter, don't
5921 read it from memory. This will allow us to save ptrace calls
5922 eventually. Changed caller single_step too.
5924 * sparc-xdep.c (fetch_inferior_registers): Avoid reading regs
5925 that we aren't going to use, saving many ptrace calls, especially
5926 when watchpointing or single stepping. Use some #define's for
5928 (store_inferior_registers): Ditto.
5929 (core_file_command): Use some #define's for constants.
5931 * tm-sparc.h: Add #define's for some register numbers, so we
5932 can eliminate the use of random constants in sparc-xdep.c.
5934 * stack.c (frame_command, print_frame_info, up_command,
5935 down_command) Remove frame_changed, since it
5936 causes a bug and doesn't seem to do anything useful. In some
5937 places it was used as a flag, in others as a stack level (?).
5939 * utils.c: Use MISSING_VPRINTF rather than HAVE_VPRINTF, so the
5940 default is to use the portable (vprintf) version rather than the
5942 * xm-news.h (MISSING_VPRINTF): Add.
5944 * valprint.c (val_print): Demangle fancy vtbl printouts. Lint.
5946 Sat Sep 8 00:24:12 1990 John Gilmore (gnu at cygint)
5948 * Remove stuff that forces -Bstatic linking of gdb, and warnings
5949 about linking debugged programs -Bstatic in the sun?os4 config
5950 files in tconfig and xconfig subdirectories.
5952 * main.c (main): Remove unreached exit(0) now that we exit
5955 * Create TODO file for online bug list. There are too many
5956 "little" bugs to keep track of on paper.
5958 * Change Projects file to refer to bug-gdb@cygnus.com
5959 rather than kingdon@ai.
5961 Fri Sep 7 23:35:15 1990 John Gilmore (gnu at cygint)
5963 * Makefile.dist (VERSION): 3.91.4 now.
5965 * symtab.c (init_misc_bunches): Rename from init_misc_functions.
5966 (condense_misc_bunches): Add sanity check that misc_count is
5967 the same as the number of symbols in the bunch.
5969 * coffread.c: rename init_misc_bunches. Pass an argument
5970 to condense_misc_bunches (a zero).
5972 * dbxread.c (partial_symbol_file_read): Call init_misc_bunches
5973 every time we are called; don't rely on our caller to do it.
5974 (add_file): Remove call to init_misc_bunches.
5976 * mipsread.c: Only warn, don't error, if unknown symbol types.
5977 This keeps an old gdb from falling on its face if it sees newly
5978 extended symbol info. Rename init_misc_bunches.
5980 Fri Sep 7 22:58:15 1990 John Gilmore (gnu at cygint)
5982 * Merge in changes from Per Bothner for DECstations and other
5983 MIPS stuff. The rest is Bothner speaking:
5985 The next message is a merger of Alessando Forin's mips port with
5986 mine. I've tried to use my good if biased judgment to get
5987 the best of both. It *does* need testing.
5989 Some of the changes are general, *not* mips-specific.
5992 Didn't believe in little-endian bit order.
5993 There are still inconsistencies about whether flags
5994 like BITS_BIG_ENDIAN are integer (#if ...) or
5995 boolean (#ifdef ...). I tried to paper over them.
5997 dbxread.c,coffread.c,mipsread.c,symtab.c,symtab.h:
5998 Moved some misc_function code that was common to
5999 {dbx,coff,mips}read.c to symtab.c.
6000 In the process, I think I cleaned things up a bit.
6001 At the same time, moved obsavestring and obconcat to symtab.c.
6004 Removed obsolete condense_addl_misc_bunches (use
6005 condense_misc_bunches(1) instead).
6008 Needed to include <sys/dir>, at least on DECstations.
6010 valops.c, mips-tdep.c, tm-mips.h:
6011 Added PUSH_ARGUMENTS macro to support funny argument-pushing
6012 conventions (when STACK_ALIGN is insufficient).
6013 Needed on mips, where doubles need 8-byte alignment,
6014 but ints only need 4.
6017 Removed cruft that was not being used.
6018 Merged in many fixes (most from Frank Yellin, fy@lucid.com).
6021 Print $ before register-names (I think that makes things a little
6023 Never print two instructions, even if one delays.
6024 Removed hex-disassemble set_cmd. (This is not mips-specific,
6025 so I think the argument is whether it is generally worthwhile or not.
6026 I'm inclined to think not, given how easy it is to
6027 convert between radixes in gdb.)
6030 This is basically Alessando's code.
6031 It doesn't use obstacks; I changed it to use obstacks
6032 in a few minor places where using malloc causes a
6033 memory leak. (Probably, more places could/should be changed.)
6034 I added record_misc_function where it was missing.
6035 In symbol_file_command and add_file_command, I tried
6036 to make the code consistent with more recent versions.
6037 Minor sylistic changes in parse_procedure.
6038 Make a .gdbinfo. psuedo-symbol point back to the real
6039 procedure symbol (using the isym field).
6042 This is basically from my port, but with a lot of details
6043 and a number of routines merged in from Alessando's version.
6044 I basically used my code "raw" backtrace (use heuristics
6045 from the actual code, rather than symbol table info) - though
6046 the idea is Alessandro's. I feel my code is a little cleaner
6047 here, particularly in being a little more flexible, such as being
6048 able to handle gcc-produced code (which it now can).
6049 It also doesn't do frame caching (which is not useful
6050 more recent gdb versions).
6051 I also used my code for push_/pop_dummy, more or less.
6052 I tried to incorporate AF's code for testing sigtramp
6053 while backtracing; I probably got it wrong.
6054 Added mips_print_register, which tries to scrunch as much
6055 information as possible on a screen...
6056 Removed the skip-prologue set_cmd. As with hex-disassemble (see
6057 under mips-pinsn.c), I don't see anything mips-specific here,
6058 and I don't see it being all that useful anyway.
6061 Added a $fp psuedo-reg distinct from $fp (nice for gcc).
6062 Use more register names (rather than hard-cases numbers).
6064 Thu Sep 6 18:33:15 1990 John Gilmore (gnu at cygint)
6066 * Hack up 3.90.11 changes:
6068 * Makefile.dist (depend): parameterize $(GCC).
6069 Add solib.c and solib.o.
6070 (readline): Fix vpath for both absolute or relative SRCDIR.
6072 * blockframe.c: Fix from Schaefer@asc.slb.com for shared libs.
6073 Also, let the part I didn't understand at least compile so
6074 I can test the rest. FIXME.
6076 * dbxread.c: Fix thinko using strcmp.
6077 (init_psymbol_list): declare static.
6078 (partial_symbol_file_open): Comment cleanups better, avoid
6079 cleaning up the string table since the caller will do that.
6080 Move the stat for mod time into symbol_file_command, temporarily.
6081 (There should be a mod time for each symbol file, eventually,
6082 to control its rereading. FIXME.)
6084 * infptrace.c (PT_WRITE_D): use same value as PT_WRITE_I for
6085 SunOS, which gives error for shared libs otherwise. (From
6086 Schaefer, probably FIXME needs work for portability.)
6088 * solib.c: Move #include "param.h" to work.
6089 Lowercase all the Uppercase Letters In the Messages.
6090 (find_solib): Clean up inferior_so_name for debug printouts.
6091 Allow no argument, to mean all shared libraries.
6093 * symmisc.c: include param.h to get CLEAR_SOLIB.
6095 Wed Sep 5 18:00:08 1990 John Gilmore (gnu at cygint)
6097 * Merge in Kingdon's changes from FSF: the diffs from 3.90.9
6098 to 3.90.11. ChangeLog entries below are from this.
6100 Wed Jun 13 09:17:39 1990 Jim Kingdon (kingdon at mole.ai.mit.edu)
6104 * Makefile.dist (HFILES): Add tm-sunos.h.
6106 Tue Jun 12 16:15:26 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
6110 * Makefile.dist (gdb.tar.Z): Change linking of config so it works.
6112 Thu Jun 7 16:22:27 EDT 1990 Jay Fenlason (hack@ai.mit.edu)
6114 * sparc-opcode.h Added single-operand version of rett.
6116 Mon Jun 4 18:12:31 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
6118 * m-sparc.h (REG_STRUCT_HAS_ADDR, STRUCT_ARG_SYM_GARBAGE):
6119 Put parens around gcc_p in expansion.
6121 Thu May 24 15:44:51 1990 Jim Kingdon (kingdon at mole.ai.mit.edu)
6123 * utils.c (lines_to_list): Return 10 if lines_per_page == 0.
6125 Wed May 23 16:36:04 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
6127 * Changes for Sun shared libraries:
6128 blockframe.c (find_pc_partial_function): If a non-text symbol
6129 is found, set *address = pc - FUNCTION_START_OFFSET.
6130 breakpoint.c (insert_breakpoints) [DISABLE_UNSETTABLE_BREAK]:
6131 Disable breakpoints instead of giving an error.
6132 source.c (select_source_symtab): Initialize cs_pst.
6133 symmisc.c: Call CLEAR_SOLIB if defined.
6134 symtab.h: Make text{low,high} CORE_ADDR not int.
6135 (psymtab): New field addr.
6137 dbxread.c: Move DECLARE_FILE_HEADERS outside functions.
6138 (record_misc_function): Give correct type for N_DATA symbols.
6139 (condense_misc_bunches): do "misc_function_count = j" regardless
6141 Take code which is shared between symbol_file_command and
6142 add_file_command and put it into partial_symbol_file_{open,read}.
6143 Split add_file_command into add_file_command and add_file.
6144 Make psymtab_to_symtab read in the string table if the file
6146 Two new parameters to read_dbx_symtab and start_psymtab.
6147 tm-sunos.h: New file.
6149 Tue May 22 17:43:03 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
6151 * infcmd.c: Change cont_command to continue_command and "cont"
6154 Mon May 21 14:41:41 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
6156 * breakpoint.c (enable_breakpoint): Get value of watchpoint.
6158 * defs.h [sparc]: Use <alloca.h> regardless of __GNUC__.
6160 * values.c (USE_STRUCT_CONVENTION): Check for structures of
6161 size 1,2,4,8 rather than size < 8.
6163 * dbxread.c (dbx_lookup_type): Do f->length *= 2 as many times
6164 as necessary, not just once.
6166 * sparc-opcode.h: Add a bunch of new opcodes which Sun as supports.
6168 Thu May 17 15:04:09 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
6170 * {t,x}m-sun386.h, sun386-xdep.c, {x,t}config/sun386
6172 * tm-news.h: Add CALL_DUMMY_*.
6174 * tm-68k.h: Remove duplicate comment at FRAME_FIND_SAVED_REGS.
6176 * config.gdb: In list_host, list_target, use ${i}, not $i.
6178 Tue May 15 21:27:12 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
6180 * source.c (find_source_lines) [BROKEN_LARGE_ALLOCA]: Use xmalloc.
6182 * sparc-opcode.h: Change all store floating-point state register
6183 instructions to have the right match & lose fields.
6185 Sat May 5 12:39:18 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
6187 * Makefile.dist: Move -I${srcdir} to GLOBAL_CFLAGS and pass
6189 config.gdb: If srcdir != ., create readline directory and
6190 copy a makefile into it.
6192 * wait.h, infrun.c: Change WRETCODE to WEXITSTATUS for
6193 consistency with POSIX.
6195 * breakpoint.c (bpstat_stop_status): Disable watchpoint
6196 when we exit its exp_valid_block.
6198 Tue Sep 4 11:46:46 1990 John Gilmore (gnu at cygint)
6200 * Makefile.dist: Bump version to 3.91.3.
6202 * Clean up handling of breakpoint commands (somewhat).
6203 Prompted by Tiemann bug report "cont 10" doesn't work any more.
6205 inferior.h: Add breakpoint_proceeded to inferior status struct
6206 and globals; save it and restore it.
6207 (clear_breakpoint_commands): Cleanup, remove old #define.
6209 infrun.c (clear_proceed_status): Set breakpoint_proceeded.
6210 (save_inferior_status, restore_inferior_status): handle it also.
6211 (proceed): Remove earlier code that set breakpoint_proceeded.
6212 It is now set only in clear_proceed_status.
6213 (clear_proceed_status): Cleanup, use bpstat_clear rather
6214 than clear_breakpoint_commands. No callers need the stop_bpstat
6215 between clear_proceed_status and proceed.
6217 infcmd.c: Add breakpoint_proceeded definition and comment.
6218 (cont_command, jump_command, signal_command): Move call to
6219 clear_proceed_status right next to call to proceed.
6221 breakpoint.c (bpstat_do_actions): Avoid clobbering our
6222 caller's argument while running down the chain of breakpoints.
6223 Use new variable "breakpoint_proceeded" to determine when
6224 a command that it executes moves the inferior past the
6226 (bpstat_clear): Handle NULL argument.
6227 (bpstat_clear_actions): Avoid useless call to
6228 breakpoint_auto_delete.
6229 (delete_breakpoint): Clean up bpstat's that are pointing to
6230 the deleted breakpoint from the stop_bpstat chain.
6231 (breakpoint_auto_delete): Simplify.
6233 * Clean up handling of EOF, error on stdin, etc. This was
6234 prompted by a network problem that caused gdb to go into an
6235 infinite loop filling up its malloc'd memory.
6237 main.c (return_to_top_level): Cleanup: call bpstat_clear_actions,
6238 not clear_breakpoints_commands, which is now gone.
6239 (main): If command_loop returns (e.g. from EOF on stdin), do
6240 a quit_command (looping back to command_loop if quit_command
6241 doesn't really quit).
6242 (command_loop): check result from command_line_input and
6243 exit if it returns NULL, rather than passing the NULL to
6245 (gdb_readline): Free malloc'd result space before returning
6248 * utils.c (query): Handle C-d to mean "yes", just as if the
6249 input was not a terminal. Also avoid infinite loop if EOF
6250 occurs in mid-input-line before newline. This allows
6251 query to be used at EOF on stdin with reasonable results.
6253 * infrun.c (proceed): Set breakpoint_proceeded.
6255 * values.c (value_as_long): Avoid infinite recursion for enums.
6256 (_initialize_values): Fix typo in help msg (kingdon).
6258 * Makefile.dist (RL_LIB): Use RL_LIB_DEP for dependencies,
6259 RL_LIB for linking. This allows -lreadline for linking
6260 and nothing for dependencies, once readline is a real library.
6262 * config.gdb: Jim Kingdon: give useful error message if the
6263 host or target type is not recognized.
6265 * defs.h (alloca): SPARC <alloca.h> does not declare alloca,
6266 it just defines it. Dumb, but deal with it.
6268 * Jim Kingdon suggests:
6269 in xconfig/sun3os4, CFLAGS should be XM_CFLAGS.
6271 Wed Aug 29 18:03:27 1990 John Gilmore (gnu at cygint)
6273 * Makefile.dist (VERSION): Bump version # to 3.91.2.
6275 * Clean up Bothner's changes.
6277 * blockframe.c (clear_pc_function_cache): New function.
6278 * blockframe.c: remake cache_pc_function_* static.
6279 * dbxread.c (symbol_file_command): remove references to
6280 cache_pc_function_* variables.
6281 * dbxread.c (read_struct_type): Use VOFFSET_STATIC.
6282 * printcmd.c: Avoid kludging a global variable (addressprint)
6283 to avoid printing the address of a string twice. Instead,
6284 pass the format letter 's' down low enough that it can be seen
6285 to avoid this problem.
6286 (print_formatted): Pass format arg to value_print.
6287 (restore_addressprint): Remove function.
6288 (do_examine): Avoid hacking addressprint, cleanups and such.
6289 (print_frame_args): Add a comment to a Bothner change.
6290 * symtab.h: define VOFFSET_STATIC and use it instead of "-1".
6291 * symmisc.c (free_all_symtabs): Call clear_pc_function_cache
6292 to wipe out the values cached in blockframe.c.
6293 * symtab.c (find_method): Add comment saying how big you must
6294 allocate to be "big enough". Per being terse again.
6295 * valprint.c (val_print): Handle format letter "s" to print
6296 strings without addresses. Add comment to vtbl printing code
6297 which casts with wild abandon. Rearrange reference-printing
6299 @0xaddr: value (print w/addressprint)
6300 value (print w/~addressprint)
6301 @0xaddr (parameter lists w/addressprint)
6302 or nothing (parameter lists w/o addressprint)
6304 Tue Aug 28 10:47:18 1990 John Gilmore (gnu at cygint)
6306 * Merge more changes from Per Bothner:
6308 Gdb's handling of TYPE_CODE_REF was so counter-C++ (and otherwise
6309 annoying) that I tried to improve it. Here are my suggestions.
6311 These patches all attempt to handle TYPE_CODE_REF (as in C++) better.
6314 Do automatic de-reference when taking the address of a reference.
6316 Don't deref_ref when printing parameter lists.
6318 More attempts at treating refernences properly.
6320 In val_print, if deref_ref==0, don't print dangling " = ".
6322 Add COERCE_REF macro, which de-references an REF.
6324 * Merge changes from Per Bothner:
6326 * Fixed (Sony news)-specific configuration problems.
6327 * Fixed other problems with using vanilla pcc and libc (enum problems;
6328 assumption that vsprintf exists).
6329 * Some major speed-ups (finc_pc_partial_function now caches a match;
6330 parsing avoids duplicate symbol_lookup calls).
6331 * Changed handling of baseclasses (no longer use baseclasses field
6332 of struct type, use the first n_baseclasses fields instead).
6333 * Various minor changes/fixes, most C++-related.
6336 Cache the most previous match from find_pc_partial_function.
6337 (Save both low and high ends of matching function's pc range.)
6338 This speeds up the loop of infrun.c:wait_for_inferior quite
6339 a bit, and makes step/next commands much zippier.
6341 Added an enum->int cast (otherwise, some compilers barf).
6343 No longer set baseclass offset to 0, since multiple
6344 inheritance now mostly works.
6345 Added a number of casts, to shut up compiler warnings
6346 (after stabs where made enums, not ints).
6347 When discarding a symbol table (in symbol_file_command),
6348 must clear the cache introduced in blockframe.c.
6349 Don't convert $vtbl_ptr_type to vtbl any more.
6350 Get rid of TYPE_BASECLASEES and baseclass_vec (see also symtab.h).
6351 Mask off sign bit emitted by g++ for virtual table offset.
6352 Set voffset to -1 (not 1) for static member functions.
6354 Changed parsing/lexing of names to avoid doing symbol lookup twice
6355 (once when lexing to determine symbol class, once for real).
6356 Now only call symbol_lookup once. Fields of 'this' win especially big.
6358 Subpress printing addr twice in the case of 'x/s addr'.
6360 lookup_basetype_type is no longer used.
6361 Add find_methods as recursive helper function to decode_line_1.
6362 This allows multiple inheritance to work.
6363 Also, once one or more matches has been found, do not look in
6364 base-classes. (Baseclass methods would be overridden, anyway.)
6366 Removed baseclasses array in struct type.
6367 Instead of using baseclasses[i], use fields[i-1].
6368 Added virtual_field_bits[i] to indicate if the i'th baseclass is virtual.
6369 Changed sign convention of voffset (previous was inconsistent).
6371 Some macros (CALL_DUMMY and relatives) were missing. Put them back.
6373 Used to assume existence of vsprintf. Re-written to not need it
6374 if HAVE_VPRINTF is undefined.
6376 typecmp was too pessimistic. Made it less so.
6378 Don't print space after address.
6379 If vtable points to a misc symbol (with 0 offset), print it,
6380 since that indicates the actual class of the object.
6381 Changed ype_print_derivation_info to use new inheritance
6382 scheme (without baseclasses vector).
6384 In value_primitive_field, fixed some bugs left over from previous set of fixes.
6385 Also, changes needed because TYPE_BASECLASSES were removed.
6387 REGISTER_U_ADDR didn't work for PC. Rewrote to use an array.
6389 Tue Aug 21 20:08:54 1990 John Gilmore (gnu at cygint)
6392 If there is no path set, and the symbols don't indicate what directory
6393 a file was compiled in, look in the current directory. But either
6394 a path or a known compilation directory will prevent this.
6397 Three independent bug fixes:
6398 * Remove the #if 0 block that breaks some stuff.
6399 * SunOS 4.1 fixed the promoted-parameter-wrong-addr bug in Sun C;
6400 adapt gdb to either SunOS 4.0.* or 4.1.
6401 * MAX_OF_TYPE and MIN_OF_TYPE thinko. By tedg@sun, I think.
6404 Instantiate the class T when looking for methods in it. (Tiemann@sun)
6407 (type_print) Demangle the name being printed.
6408 (type_print_base) Handle botched demangling without coredump (tiemann).
6411 (check_stub_method): Document routine.
6412 (tiemann) fix bug for no-arg functions
6413 Avoid clobbering beyond end of malloc'd storage.
6414 Terminate the argument list properly.
6416 Sat Aug 18 01:29:59 1990 Per Bothner (bothner@cs.wisc.edu)
6418 * Changes merged by John Gilmore:
6421 In breakpoint_1, use new print_address_symbolic instead
6422 of find_pc_partial_function. (This forces use of assembler-level
6423 addresses, and avoids misleading non-mangled source-level names.)
6425 Generalize ansi argument such that -1 means skip arglist totally.
6426 Removed global variable print_ansi_qualifiers (which made
6427 code non-reentrant), in favor of extra explicit arguments
6428 to internal routines.
6430 Add new helper function print_address_symbolic.
6431 Use find_pc_misc_function instead of find_pc_partial_function
6432 (since we want assembler-level symbols here).
6434 Print unknown function as just "f (...)", not "f (...) (...)".
6435 Use new fputs_demangled explicitly.
6437 Fixed a typing violation (problem: value.h cannot be imported
6438 without renaming many variable in this file).
6439 lookup_symbol: If no matching misc_func, look for a C++-mangled name.
6440 decode_line_1: Moved forward some never-reached code.
6441 Made decode_line_2 skip function prologues correctly.
6443 fputs_filtered should not demangle by default.
6444 Add new fputs_demangled to demangle on demand..
6446 Change value_struct_elt to use value_primitive_field (using recursive
6447 utility function search_struct_field). This allows foo.bar to work
6448 for multiple inheritance (so far only for data fields).
6449 Change check_field in the same way (recursive helper function
6450 to support multiple inheritance).
6451 (Note: there are more of these problems that I haven't fixed.
6452 Any code that says TYPE_BASECLASS (t, 1) is probably wrong.)
6453 value_of_this: 'this' symbol name is now just "this", note "$this".
6455 Don't print static members.
6456 Avoid printing "members of <type>" if there are none.
6457 Simplified type_print_derivation_info by merging duplicate code.
6458 Remove useless blank lines in type_print_base (ptype command).
6460 Added declaration of new routine value_primitive_field.
6462 Added value_primitive_field which is generalized version of
6463 value_field that can handle multiple inheritance (non-zero offsets etc).
6464 Re-implemented value_field to call value_primitive_field.
6466 Fri Aug 17 23:33:44 1990 John Gilmore (gnu at cygint)
6468 * infcmd.c -- insert else to avoid 'delete env' coredump when you
6469 delete the whole environment. Karl Berry reported the bug.
6470 * source.c - fix openp to avoid //'s in filenames, which
6471 trigger an Emacs bug causing it to not be able to find files
6472 when running gdb in a window.
6473 * dbxread.c - zap the #if 0 that botches the add-file code.
6474 It seems to work a lot better without all the code commented out.
6476 Fri Jul 20 16:58:46 1990 John Gilmore (gnu at cygnus.com)
6478 * Merge Tiemann's and Ted Goldstein's changes, detailed below,
6481 Tue Jul 17 19:34:33 1990 Ted Goldstein (tedg at golem)
6483 * Makefile - added a ${CFLAGS} to a couple of entries,
6484 added remote-sa.sparc.c
6485 * added remote.sa-sparc.c, a modification of remote.c
6486 which conducts a dialog directly with the SparcStation prom.
6487 * breakpoint.c, infrun.c, sparcdep.c added
6488 remote_insert_breakpoint(), and remote_remove_breakpoint()
6489 to breakpoint.c instead of directly writing breakpoint instructions.
6490 * sparcdep.c on remote_debugging,there is no need
6491 to remove signle step breakpoint instructions.
6492 * main.c added "-epoch" flag and "int epoch_interface" to main.c
6494 * printcmd.c - epoch interface sends lisp expressions to open up
6495 epoch windows on inspection.
6496 * valprint.c - added arrayprint, and addressprint and made adding
6497 format controls easier
6498 * wait.h added a couple of undef's because we were getting
6499 complaints about WSTOPSIG and WTERMSIG begin redefined.

6595 step_resume_break_address != NULL, even if another_trap.
6596 If trap_expected and we enter sigtramp, then set up a
