59 Eliminate TYPE_MAIN_VARIANT and TYPE_NEXT_VARIANT. Eliminate
60 lookup_method_type. Add TYPE_TYPE_SPECIFIC macro.

70 Change some C++ parsing error()s to complain()ts.
71 * buildsym.c, findvar.c, printcmd.c, symtab.c: Make unions and
72 structs have the same representation and work the same as far as
74 * buildsym.c, symtab.c, values.c: Remove all references to
75 TYPE_MAIN_VARIANT and TYPE_NEXT_VARIANT.
77 * valops.c: Improve comments and indentation. Only call
78 check_stub_method when the stub flag is on.
79 * valprint.c: Fix or mark minor bugs and unportabilities.
81 * coffread.c (anonymous unions): Allocate a cplus structure.
83 * mipsread.c: Eliminate "template" types. Build new, real
84 types whenever we need them. Allocate cplus structures as needed.
85 Bulletproof the type parsing a bit more. Mark storage leaks.
86 (parse_type): Copy TYPE_TYPE_SPECIFIC when copying a real type
87 on top of a partial type.

92 print a message if any of them fail.
93 (terminal_ours_1): Store result of ioctl's for debugging, but
94 don't print (the terminal isn't ours...).
96 * tm-tahoe.h (FRAME_ARGS_ADDRESS): No need to offset from frame
99 * m2-exp.y (MAX, MIN): Rename to MAX_FUNC, MIN_FUNC to avoid
100 conflicts with system header files.
102 Fri Nov 22 08:27:40 1991 John Gilmore (gnu at cygnus.com)
104 * Roll VERSION to 4.2.95.
106 * buildsym.c, coredep.c, mem-break.c, xcoffread.c: Put <stdio.h>
107 first, before defs.h.

109 * configure.in: Handle i386-none-aout rather than i386-aout-none.
110 * infptrace.c, language.h, utils.c: Lint.
111 * m2-exp.y: #undef MAX and MIN in case system includes set them.
112 * xm-tahoe.h: Set HOST_BYTE_ORDER. Include system versions of
113 {BIG,LITTLE}_ENDIAN and the INT_MAX family first, to avoid
114 redefinition warnings.
115 * defs.h: Reorder things so that the xm-file gets first crack
116 at #define's, followed by defs.h and then the tm-file.
117 * Makefile.in: Remove spaces after 'ignore exit code' - flags.

124 Thu Nov 21 18:26:11 1991 Fred Fish (fnf at cygnus.com)
126 * dwarfread.c (struct_type): Must initialize the c++ specific
127 portion of union types as well as struct types, since gdb attempts

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

208 * blockframe.c: Remove tdesc-related code. Default
210 * infrun.c: Remove tdesc-related code.
211 * m88k-tdep.c (frame_chain_combine, init_frame_pc): Remove copies
212 of defaultable things.
213 * tm-m88k.h: New file, common to all Moto 88k target configs.
214 Derived from tm-delta88.h.

224 Mon Nov 18 13:51:37 1991 Per Bothner (bothner at cygnus.com)
226 * source.c (open_source_file): If openp fails, try again
227 using just the base (non-directory) part of the filename.
228 This solves various annoying problems, such as when the
229 source was compiled with an absolute pathname - and the
230 source files have moved. Or if the source was compiled
231 using a relative pathname, it can be more convenient
232 to just specific the source directory to the dir command.
234 Mon Nov 18 00:04:41 1991 Fred Fish (fnf at cygnus.com)
236 * cplus-dem.c (munge_function_name): Add missing third arg to
237 instance of call to do_type().

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

249 TYPE_CPLUS_SPECIFIC unless TYPE is TYPE_CODE_STRUCT.
250 * buildsym.c (read_type): Allocate TYPE_CPLUS_SPECIFIC for
252 (read_struct_type): Ditto. Also, add comments about how we can
253 deduce TYPE_VPTR_FIELDNO from inheritance info and fieldname info.
254 * coffread.c (decode_base_type): Allocate TYPE_CPLUS_SPECIFIC for
256 (read_struct_type): Ditto.

275 * symfile.c: Add function compact_misc_function_vector() to
276 remove duplicate misc function vector entries. See comments
277 in source for why this is necessary/desirable.
279 * dwarfread.c: Add misc function type parameter to internal
280 record_misc_function(). Remove calls to init_misc_bunches()
281 and condense_misc_bunches(), these are now done in elfread.c.
283 * elfread.c: Add support for reading bfd canonical symbol tables
284 and generating misc function vector entries for global and
285 absolute symbols. Do calls to init_misc_bunches() and
286 condense_misc_bunches() where they will enclose all calls to
287 record_misc_function(), including those in dwarfread.c.
289 Thu Nov 14 17:02:11 1991 Roland H. Pesch (pesch at cygnus.com)
291 * doc/Makefile.in: new targets gdb.me, gdb.ms, gdb.mm
292 (roffable documentation).
293 * doc/gdb.texinfo: embedded hints (as comments) for better
294 texi2roff conversion.

316 from i960-tdep.c and adapt to the function prologues on the 88k.
317 (read_next_frame_reg): Borrow from mips-tdep.c.
318 FIXME: frame_locals_address should go away.
320 * tm-delta88.h: Dump all the tdesc stuff.
321 Macros for all frame-related stuff call fns of same name.
322 Remove duplicated definitions. FP_REGNUM becomes same as
325 * xm-88k.h: Eliminate lots of library dependencies, now handled
326 in libiberty. Eliminate KDB nonsupport.
328 * doc/gdbint.texinfo: Add rudiments on frames. FIXME, add more.

356 Fixes to support C++ methods with functional parameters.
357 * c-exp.y (func_mod rule): Allow (and ignore) list of parameter
358 types in a function type.
359 * eval.c (parse_and_eval_type), value.h: New function,
360 parse_and_eval_type, is based on old code from check_stub_method.
361 But don't actually evaluate the cast, since that calls
362 value_cast(), whcih may fail. Just extract the type
363 from the parsed expression.
364 * values.c (check_stub_method): While looping through the
365 arguments, adjust depth *after* parameter has been handled.
366 Replace call and setup of parse_and_eval with new function

414 This includes a "struct objfile" that owns symtabs and psymtabs
415 that were read in from that binary file.
417 * symfile.h: Add struct objfile. Add pointer to the objfile
418 into the struct sym_fns.

490 * symfile.h, symfile.c, symtab.h: Lint
492 Fri Nov 8 23:38:48 1991 John Gilmore (gnu at cygnus.com)

501 Thu Nov 7 18:26:15 1991 Steve Chamberlain (sac at rtl.cygnus.com)
503 * Makefile.in: link with libiberty after libreadline, since
504 readline might want something in libiberty.
505 * m88k-xdep.c: Fixed the register offsets in the ptrace_user
506 struct for BCS 88k machines.
507 * xm-m88k.h: don't define USIZE if already defined.
508 * configure.in: Added delta88 target.
510 Thu Nov 7 04:51:19 1991 John Gilmore (gnu at cygnus.com)
512 * am29k-pinsn.c, am29k-opcode.h: Fix decoding of mtacc, dmac, fmac.
514 * tm-*.h: Remove READ_DBX_FORMAT, COFF_FORMAT, and
515 READ_MIPS_FORMAT, which have been unused since BFD. Still
516 remaining is COFF_NO_LONG_FILE_NAMES.
517 * tm-sun3.h, tm-altos.h: Remove detritus accidentally left from
518 function calling code moved to m68k-tdep.c.
520 Wed Nov 6 17:21:59 1991 John Gilmore (gnu at cygnus.com)
522 * coffread.c: Eliminate c_nsyms in favor of c_naux.
523 Complain if no auxents on .bf and .ef FCN symbols, and assume
524 lots of line numbers.
525 (init_linenos, enter_linenos): Use a sentinel at the end of the
526 read-in linenos, to make for a fast, safe loop-end test.
528 Wed Nov 6 02:54:08 1991 Steve Chamberlain (sac at cygnus.com)
530 * coffread.c (read_coff_symtab): coffread used to rely on the
531 x_sym.x_misc.x_lnsz.x_lnno field giving the # of linnos in a
532 function. Two of the formats I'm using (29k and 88k) don't seem to
533 set it. Ths patch to fcn_last_line and (enter_linenos) is an
534 attempt to use the actual size of the linno table in the file to set
535 the number of linenos to process.
537 Tue Nov 5 22:47:46 1991 Steve Chamberlain (sac at cygnus.com)
539 * Makefile.in: put a - infront of the mv y.tab.c c-exp.tab.c and
540 mv y.tab.c m2-exp.tab.c, so that if bison is used, and the files
541 are created in place, so the mv fails, then the make continues.
543 Tue Nov 5 16:47:47 1991 Per Bothner (bothner at cygnus.com)
545 Add C++ as a separate language.
546 * defs.h (enum language): Add language_cplus.
547 * dwarfread.c (end_symtab): Support language_cplus.
548 * c-exp.y: Add new struct language_defn cplus_language_defn.
549 Don't set c to be the default language (see main.c).
550 * c-exp.y (yylex): Only look for field of this if
551 language is C++. (First difference from C!)
552 * language.c: Add case branches for C++ (currently, all
553 the same as C). Also, add c++ to "usage" note for "set lang".
554 * valprint.c (typedef_print). Add case branches for C++.
555 * main.c (main): New way to set initial language: Look at
556 file extension of psymtab containing main(). (Same as we
557 do for symtabs, but avoid loading the symtab yet.)
558 * symtab.c: New routine find_main_psymtab(), used by main()
559 to set initial language.
560 * symfile.c (allocate_symtab): Move code for mapping file
561 extensions-> languages to new deduce_language_from_filename().
563 Fix a C++ problem when looking for methods in super-classes.
564 There was confusion between base and derived types.
565 * valops.c (value_fn_field): Change function interface.
566 * values.c: Use new value_fn_field interface.
568 Mon Nov 4 10:49:33 1991 Per Bothner (bothner at cygnus.com)
570 * infrun.c: Fixed typo in comment.
571 * utils.c: All the v*fprintf emulation is now in libiberty,
572 so we can get rid of some junk.
573 * xm-sun3os4.h, xm-sun4os4.h, xconfig/decstation, xconfig/i386sco,
574 xconfig/sun3os4, xconfig/sun4os4: Don`t need HAVE_STRSTR any more.
575 * m68k-pinsn.c (print_insn_arg): Support BB/BW/BL
576 type operands, as used by branch instructions.
577 * gmalloc.c: Fix prototype of memcpy.
578 * elfread.c: Comment out register_addr, since it conflicts
579 with the one in coredep.c.
580 * buildsym.h: Remove extern declarations of two functions
581 that are really static in buildsym.c.
582 * tm-mips.h: Add symbolic names for more registers.
583 * mips-xdep.c (store_inferior_registers): Use new register names.
584 * xm-mips.h: Simplify REGISTER_U_ADDR, since it is now
585 only used for core files, not ptrace. Therefore,
586 the KERNEL_U_ADDR hack is no longer needed.
587 The mapping to ptrace number is now in in mips-xdep.c.
588 * mips-xdep.c: Define REGISTER_PTRACE_ADDR (using the
589 mapping from the old REGISTER_U_ADDR), and use it
590 in {fetch,store}_inferior_registers.
591 * mipsread.c: Rename #include ecoff.h to new name coff-mips.h.
592 * mips-tdep.c (mips_push_dummy_frame, mips_pop_frame):
593 Save/restore FP regs correctly (?).
594 * dbxread.c: Remove duplicate define_symbol and type_synonym_name
595 (these had been previously moved to buildsym.c).
596 Hence, define_symbol becomes extern instead of static.
597 * buildsym.c (read_struct_type): Comment out bogus handling
598 of C++ operator methods. Minor hacking of reading of class
599 contexts. Make define_symbol non-static, so dbxread.c can call it.
601 Fri Nov 1 11:05:47 1991 John Gilmore (gnu at cygnus.com)
603 * mipsread.c (read_mips_symtab, read_the_mips_symtab): Use real
604 filename with error messages.
605 * stack.c (frame_select_command): Rename to select_frame_command
606 to avoid "fr" and "fra" having nonunique completions.
607 * symfile.c (sort_symtab_syms): Ignore sort of zero symtab *.
608 (symfile_init): Print file format name when unable to handle it.
609 (free_named_symtabs): Use BLOCKVECTOR rather than obsolete BLOCKLIST.
610 * symmisc.c (free_symtab): Only free linetable if nonzero.
611 * symtab.h: Remove obsolete BLOCKLIST macros.
613 Thu Oct 31 18:12:43 1991 Stu Grossman (grossman at cygnus.com)
615 * infrun.c (wait_for_inferior): another stepi/nexti fix. Ensure
616 that stop_step is 1 at bottom of main loop. I don't know why this
617 needs to be done, but it helps me sleep better at night.
619 Sun Oct 27 18:18:39 1991 Stu Grossman (grossman at cygnus.com)
621 * main.c (initialize_history): Read history after reading all
624 Sun Oct 27 14:09:25 1991 John Gilmore (gnu at cygnus.com)
626 * buildsym.c: Break out initial malloc sizes.
627 (record_line): Record directly in a subfile. Alloc on demand.
628 (compare_line_numbers): Add from xcoffread.c.
629 (end_symtab): New params say whether to sort pendings and
630 linetable. Patch block stabs if defined. Shrink linetable before
631 allocating the symtab.
632 * buildsym.h: Delete line_vector* and prev_line_number. Add
633 global_stabs and file_stabs for xcoffread.
634 * dbxread.c (start_subfile): Move to buildsym. Change above calls.
635 * symtab.h: LINETABLE(symtab) can now be null. Zap LINELIST.
636 * symmisc.c, symtab.c: Cope with null LINETABLEs.
638 * blockframe.c: Pass fromleaf to INIT_EXTRA_FRAME_INFO.
639 * tm-29k.h, tm-88k.h, tm-i960.h, tm-irix3.h, tm-mips.h, tm-pyr.h,
640 tm-sparc.h: Accept fromleaf parameter.
641 * c-exp.y (yyerror): Pass error message if given.
642 * configure.in: Add rs6000 host and target.
643 * inflow.c (new_tty): O_NOCTTY kludge for RS/6000.
644 * symfile.h (entry_point): Add.
646 Sat Oct 26 00:16:32 1991 John Gilmore (gnu at cygus.com)
648 * buildsym.c: New file. Breaks out symbol-table-building routines
649 from dbxread.c, so they can be shared with xcoffread.c.
650 * buildsym.h: New file. Declarations for buildsym.c users.
651 * dbxread.c: Remove large chunks into buildsym.c.
652 * Makefile.in: Add buildsym.c and buildsym.h.
654 * symfile.c (syms_from_bfd): New routine.
655 (add_symbol_file): Call it to do the real work.
656 (syms_from_bfd): Initialize entry_point before calling symfile_init.
657 * symtab.h, symfile.c, coffread.c, mipsread.c, dwarfread.c:
658 Avoid declaring or setting entry_point (symfile.h & symfile.c cope).
660 Fri Oct 25 10:58:16 1991 Mark Eichin (eichin at cygnus.com)
662 * cplus-dem.c (cplus-demangle): added support for templates, static
663 data, and the new (correct) mangling for destructors.
665 * dwarfread.c: (dwarfwarn): created a varargs version of
666 dwarfwarn, for non __STDC__ compilers.
668 * c-exp.y: (yylex): added match for "template" token.
669 (typebase): added TEMPLATE name '<' type '>' clause, for explicit
670 specification of template types.
672 * symtab.c: (lookup_template_type): new function for finding
673 templates in symbol table.
674 (type_name_no_tag): changed to explicitly check for s/u/e at the
675 beginning of the symbol - if it is a template, none of these will
676 be there (but the name will still contain spaces.)
678 Fri Oct 25 18:59:32 1991 Per Bothner (bothner at cygnus.com)
680 Various fixes to improve g++ debugging.
681 * symtab.h: Add is_const and is_volatile flags for each method.
682 These are bit fields - take their space from voffset,
683 which shrinks to 30 bits. Since voffset is now a bitfield,
684 make it unsigned for portability. This changes its interpretation
685 slightly: Static methods now have voffset 1 instead of -1,
686 and virtual offsets start at 2, not 1.
687 * symtab.c: Renamed gdb_mangle_typename to gdb_mangle_name,
688 since it now returns an entire magled method name, not just
689 the type part. This avoids some duplication.
690 It also allows us to correctly mangle const and volatile
691 methods (using the new is_const and is_volatile bit fields
693 * valprint.c (type_print_base), values.c (check_stub_method):
694 Simplify by using new gdb_mangle_name.
695 * values.c (value_headof): Fix to correctly handle single
696 inheritance (actually two fixes, either of which suffices).
697 * dbxread.c (read_struct_type): Handle const and volatile
699 * dbxread.c (read_struct_type): Yet one more place where
700 we must handle '\\' continuations.
701 * valprint.c (vtbl_ptr_name): Add final '\0'.
703 Fri Oct 25 16:06:38 1991 Stu Grossman (grossman at cygnus.com)
705 * tm-sparc.h, tm-68k.h (EXTRACT_RETURN_VALUE): fix output of
706 short return values for sparc and 68k. Patch from Paul Eggert.
708 * coffread.c, coredep.c, i386-xdep.c: install patches for
709 SysV/386 3.2 from Mauro DePalma.
711 Fri Oct 25 02:02:13 1991 John Gilmore (gnu at cygnus.com)
713 * core.c (core_file_info), exec.c (exec_file_info): Print file
714 type. Use printf_filtered.
716 * valops.c (value_fetch_lazy): Avoid 0-length fetches.
718 Thu Oct 24 23:06:40 1991 Fred Fish (fnf at cygnus.com)
720 * dwarfread.c: Add casts to remove compiler warnings.
722 * tm-3b1.h, tm-68k.h, tm-altos.h, tm-amix.h, tm-hp300bsd.h,
723 tm-hp300hpux.h, tm-isi.h, tm-news.h, tm-pn.h, tm-sun2.h,
724 tm-sun3.h: Remove locally duplicated code for calling functions
725 in the inferior. The only differences were in the specific trap
726 vectors used and whether or not an fpu was present. These are
727 now handled by appropriate definitions of BPT_VECTOR and
728 HAVE_68881 respectively. Other minor obvious cleanups.
730 * valops.c: Correct a minor misspelling.
732 * utils.c: Remove local BSD/USG hacks that are now in libiberty.
734 * dwarfread.c: Remove prototype for dwarfwarn. Does not work
737 Thu Oct 24 09:33:44 1991 John Gilmore (gnu at cygnus.com)
739 * stack.c (frame_command): Always print. Use new
740 frame_select_command to select a frame without printing.
742 * dwarfread.c: Use <varargs.h>, since <stdarg.h> is not portable.
744 Thu Oct 24 01:32:51 1991 Fred Fish (fnf at cygnus.com)
746 * dwarfread.c: New file for DWARF debugging format support.
748 * elfread.c: New file for ELF object file format support.
750 * procfs.c: New file for SVR4 /proc (process file system) support.
752 * tm-amix.h, xm-amix.h, tconfig/amix, xconfig/amix: New files for
755 * xm-svr4.h, tm-svr4.h: New files for SVR4 support.
757 * xm-m68k.h: New file for host machines with m68k cpu.
759 * Makefile.in: Add elfread.c and dwarfread.c to SFILES_MAINDIR.
760 Add elfread.o and dwarfread.o to OBS.
762 * symfile.h: Add "elf" to list of supported formats in comment.
764 * c-exp.y, defs.h, symtab.h, valprint.c: Add three new builtin
765 types to gdb, builtin_type_long_double, builtin_type_complex, and
766 builtin_type_double_complex. Add and use new TARGET_SHORT_BIT,
767 TARGET_INT_BIT, TARGET_LONG_BIT, TARGET_FLOAT_BIT,
768 TARGET_DOUBLE_BIT, TARGET_LONG_DOUBLE_BIT, TARGET_COMPLEX_BIT, and
769 TARGET_DOUBLE_COMPLEX_BIT, as the sizes in bits of the indicated
770 types on the target machine (ala the existing TARGET_LONG_LONG_BIT).
772 * infrun.c: When using SVR4 /proc interface instead of ptrace(),
773 call proc_set_exec_trap() to setup child to stop at first instruction.
775 * inftarg.c: When using SVR4 /proc interface, call proc_wait()
778 * m68k-tdep.c: Add new routines supply_gregset(), fill_gregset(),
779 supply_fpregset(), and fill_fpregset(), which are machine
780 dependent support routines for SVR4 /proc interface.
782 * utils.c: Add warning_setup() and warning(). Warning() behaves
783 the same as error() except that it returns normally rather than
784 jumping back to command level. Modules that don't want to call
785 warning() for some reason, but want to produce their own warnings,
786 can call warning_setup() to ensure compatibility with the way
787 warning() and error() deal with the terminal.
789 * symtab.c: Make internal errors produce more useful messages.
791 * tm-68k.h: Move code that is duplicated in almost every single
792 m68k based machine's configuration files to this common file.
793 Duplications in the configuration files still need to be removed
796 * infrun.c (child_create_inferior): System V versions must call
797 setpgrp() with no arguments, to comply with prototyping typically
800 * munch: Add support for SVR4 style nm output.
802 * dbxread.c, mipsread.c symmisc.c, symtab.c: Remove the object
803 file specific fields from the partial symbol table structure and
804 replace them with a pointer to private data for each different
805 flavor of object file reader to initialize appropriately.
807 Wed Oct 23 09:38:20 1991 John Gilmore (gnu at cygnus.com)
809 * xconfig/sun[34]os4: Add note about strstr botch on sunos4.0.3c
812 * mipsread.c (fixup_undef_type): New function. If a struct /
813 union / enum is defined in a header file but nowhere else used,
814 (by typedefing, pointer referencing or declaration) the mipsread code
815 builds the complete tree for the structure but leaves its code as
816 TYPE_CODE_UNDEF as it doesn't know what kind of aggregate it is.
817 Guess its type based on the details of the members.
819 Tue Oct 22 18:04:32 1991 Stu Grossman (grossman at cygnus.com)
821 * infrun.c (wait_for_inferior): Check return value from
824 Mon Oct 21 17:47:03 1991 Stu Grossman (grossman at cygnus.com)
826 * infrun.c (wait_for_inferior): fix stepi/nexti that was broken
827 by my last edit to this routine.
829 Mon Oct 21 14:27:43 1991 John Gilmore (gnu at cygnus.com)
831 * tm-sun3.h (FIX_CALL_DUMMY): problem with cross debugging.
832 FIX_CALL_DUMMY does unaligned accesses and/or forgets to byte swap
833 the values before putting them into the dummy code. (From Peter
836 Mon Oct 21 10:04:39 1991 Steve Chamberlain (steve at rtl.cygnus.com)
838 * configure.in: added ebmon target.
840 Wed Oct 16 22:49:58 1991 John Gilmore (gnu at cygnus.com)
844 * Makefile.in: Roll VERSION to 4.2.
845 * README, TODO, WHATS.NEW: Update.
847 * core.c (core_open): Improve error message for bad file.
848 Pass .reg virtual memory address to fetch_core_registers to help
849 it find the registers in the core-file header.
850 * coredep.c (fetch_core_registers): Take new argument, use it,
851 and pass it to register_addr to locate the block of registers.
852 * xm-mips.h: Update KERNEL_U_ADDR for new scheme. Cleanup a bit.
854 * dbxread.c (read_dbx_symtab, process_one_symbol): Handle
855 Sequent N_FN_SEQ like everybody else's N_FN.
857 * main.c: Circumvent SCO cc bug with #if !!defined(USG).
858 * tm-i386v.h: #endif guck.
859 * xconfig/i386*: Remove -Dgetpagesize()=4096 kludge.
860 * xconfig/i386sco: Add HAVE_STRSTR to avoid ANSI bdeath.
861 * xconfig/tahoe: Add REGEX, which seems to be missing.
863 * coredep.c: Add <sys/types.h> for SCOnix.
864 * dbxread.c (read_dbx_symntab): Avoid coredump on malformed file.
865 * printcmd.c (print_formatted): Flush output before disassembly.
867 Tue Oct 15 20:12:32 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
869 * doc/refcard.tex (sec "Working Files"): consistent metavars and
870 other improvements, due to comments by François Pinard
871 (pinard@iro.umontreal.ca)
873 * doc/gdb.texinfo (appendix "Installing GDB"): changes in
874 configure, and improvenets related to Pinard's refcard comments
876 Tue Oct 15 08:45:12 1991 John Gilmore (gnu at cygnus.com)
878 Changes from Fred Fish:
879 * tm-68k.h (FPI_REGNUM): Add.
880 * infrun.c (child_create_inferior): flush stdout and stderr
882 * configure.in: Handle amigados, amix hosts and targets.
883 * inflow.c: Handle TIOCGLTC_BROKEN for Amiga.
886 * values.c (show_convenience): Use printf_filtered.
887 * main.c (define_command): Check result of lookup_command for
889 (echo_command): Use printf_filtered, and force output out.
891 * dbxread.c (read_enum_type): Avoid Modula-2 kludge that breaks C
893 * i387-tdep.c (double_to_i387): Fix typo for double_to_ieee_extended.
894 * utils.c (_initialize_utils): If !ISATTY, don't paginate.
895 * configure.in, tconfig/decstation, xconfig/decstation: Rename
896 dec3100 to decstation.
898 Mon Oct 14 13:37:50 1991 Roland H. Pesch (pesch at cygnus.com)
900 * doc/gdb.texinfo: Catch up to changes recorded here in ChangeLog
901 (nodes Continuing and Stepping; Memory; Targets) clarifications
904 Fri Oct 11 23:27:06 1991 John Gilmore (gnu at cygnus.com)
906 * tm-{irix3,mips,nindy960,pn,symmetry,vx960}.h: Move
907 REGISTER_U_ADDR to corresponding xm- file. Sugg. by Peter Schauer.
909 * symmisc.c (print_partial_symtabs): Add printpsyms debug cmd.
911 * m68k-tdep.c (m68k_push_dummy_frame, m68k_pop_frame): Add
912 generic routines for calling inferior functions.
914 * blockframe.c (inside_main_scope, inside_entry_scope): New.
916 * copying.awk: Filter formfeeds out of copying & warrantee.
917 Make them available as `show copying' and `show warrantee' also.
918 * main.c (print_gnu_advertisement): Advt `show' commands.
920 Thu Oct 10 17:25:47 1991 John Gilmore (gnu at cygnus.com)
922 * mach386-xdep.c: Even when cross-compiling, leave in the
923 core-file reading code.
924 * core.c (get_core_registers): Avoid coredump if no .reg section.
926 Wed Oct 9 17:03:34 1991 John Gilmore (gnu at cygnus.com)
928 * mipsread.c, coffread.c: initialise TYPE_VPTR_FIELDNO to -1.
929 This avoids coredumps under `set print object on' in value_headof
930 (called erroneously by value_from_vtable_info) for `p &struct'
931 or `p *struct'. From Peter Schauer.
933 Mon Oct 7 00:06:52 1991 John Gilmore (gnu at cygnus.com)
935 * Makefile.in: Roll version to 4.1.2.
936 * dbxread.c: Use aout64.h, not a.out.gnu.h. Get external symbol entry
937 size from BFD (but, FIXME, we don't yet read external nlists's and
938 convert them to internal nlists's before handling them -- we still
939 assume they have the same size and alignment.) Use SET_NAMESTRING
941 * exec.c (exec_file_command): Move dead coff-encapsulation code
943 * m88k-tdep.c, m88k-xdep.c: Remove encap test and #inc <a.out.h>.
945 Fri Oct 4 22:30:06 1991 John Gilmore (gnu at cygnus.com)
947 * configure.in, tm-i386v.h, xm-i386v.h: Intel 386 Mach host port.
948 * xm-i386mach.h, mach386-xdep.c, xconfig/i386mach: New files.
950 Fri Oct 4 17:04:31 1991 Per Bothner (bothner at cygnus.com)
952 More patches from Peter Schauer <pes@regent.e-technik.tu-muenchen.de>:
953 * mips-xdep.c (store_inferior_registers): Don't try to
954 write the (pseudo) FP.
955 * mipsread.c (parse_partial_symbols): Improved algorithm for
956 setting pst->texthigh.
958 Fri Oct 4 16:47:32 1991 Roland H. Pesch (pesch at cygnus.com)
960 * doc/Makefile: make TEXINPUTS include . everywhere
962 Fri Oct 4 00:35:56 1991 John Gilmore (gnu at cygnus.com)
964 * coffread.c, dbxread.c, symfile.c, symmisc.c, symtab.h: Remove
965 vestiges of typevectors, which were for symsegs and are no longer
966 used. (From a question by Eliot Dresselhaus
967 <dresselh@RFT30.nas.nasa.gov>).
969 Thu Oct 3 09:33:26 1991 John Gilmore (gnu at cygnus.com)
971 * dbxread.c, coffread.c: static-ize functions that were
972 gratuitiously external. (From Fred Fish.)
974 * c-exp.y: sym->class to SYMBOL_CLASS (sym).
976 * dbxread.c (dbx_lookup_type): Keep doubling size of typevector
977 until it is large enough.
979 * dbxread.c (read_type): Handle error case slightly better.
980 Make complaint message not C++-specific.
982 Wed Oct 2 17:21:07 1991 Stu Grossman (grossman at cygnus.com)
984 * infrun.c (wait_for_inferior): Fix step/next so that you only
985 stop at the beginning of a new line. This fixes various problems
986 with for loops, nested if-else's and switch statements.
988 Tue Oct 1 06:33:55 1991 John Gilmore (gnu at cygnus.com)
990 * symtab.c (lookup_symtab_1, lookup_symbol): "fatal" errors
991 between symtabs and psymtabs become ordinary error()s.
993 * dbxread.c (read_dbx_symtab): Relocate end_of_text_addr
994 properly, making "end pc" correct in shared lib psymtabs.
995 (From Guy Harris <guy@auspex.com>.)
997 Mon Sep 30 13:15:31 1991 John Gilmore (gnu at cygnus.com)
999 * dbxread.c: Enable, but soften, const_vol_complaint.
1000 (read_dbx_symtab): N_STSYM and N_LCSYM define static vars.
1001 Ditto Gould N_NBSTS and N_NBLCS. Also, all types in the psymtab
1002 should be file-scope, not global.
1003 (read_struct_type): Remove ancient multiple-inheritance warning.
1004 (read_range_type): Check base type, complain & patch if undefined.
1005 * stack.c (frame_info): Demangle the function name in `info stack'.
1006 (From Peter Schauer)
1008 Sat Sep 28 10:02:33 1991 John Gilmore (gnu at cygnus.com)
1010 * eval.c (evaluate_subexp_for_address): Don't use
1011 TYPE_POINTER_TYPE directly (it might be zero if this type has
1012 never had a pointer created before); use lookup_pointer_type.
1013 * symtab.c (lookup_method_type): Arguments were swapped in all
1014 callers, so fix it here. I'm amazed this worked at all!
1016 Fri Sep 27 18:09:31 1991 John Gilmore (gnu at cygnus.com)
1018 * c-exp.y, m2-exp.y: Define more yysymbols that happen to be
1019 "bss" rather than "data" symbols, but which still conflict.
1022 * coffread.c (coff_symfile_read): Use xmalloc, not malloc.
1023 * core.c (core_files_info): Shorten output.
1024 * exec.c (exec_files_info): Ditto.
1025 (build_section_table): Ignore zero-length sections.
1026 * language.c, printcmd.c: Lint.
1027 * language.h (get_frame_language): Declare.
1028 * saber.suppress: update.
1029 * stack.c (find_relative_frame): Remove complex code that was
1030 #if 0'd, stick with simple code. Lint.
1031 * saber.suppress: Update a bit.
1032 * symfile.c (add_symbol_file_command): Add "?" to question.
1033 * utils.c (parse_escape): Avoid \a due to bdead compilers.
1034 * value.h: Declare typedef_print.
1036 * valprint.c (val_print, type_print_base): TYPE_CODE_RANGE less
1039 * nindy-tdep.c (nindy_frame_chain_valid): Use lookup_misc_func.
1040 (Reported by Mark Peek <mark@imagen.com>.)
1042 * solib.c (solib_map_sections): Relocate all sections, even
1043 though only the text section's size is tracked. Mark ld_text
1044 for eventual elimination as we generalize to N sections.
1046 * infrun.c (wait_for_inferior): Don't check if the PC is in a
1047 call_dummy if we were stopped by a random signal that is being
1048 passed to the program. This produced wierd results when calling
1049 functions in the inferior and signals (e.g. SIGALRM) were in use.
1051 Tue Sep 24 18:05:30 1991 John Gilmore (gnu at cygnus.com)
1053 * infrun.c (IN_SIGTRAMP): Not parenthesized properly.
1054 Bugfix from Paul Eggert <eggert@twinsun.com>.
1055 * tm-ultra3.h (IN_SIGTRAMP): Ditto.
1056 * valprint.c (print_floating): Print 9 digits for IEEE floats.
1059 Mon Sep 23 15:50:07 1991 John Gilmore (gnu at cygnus.com)

1069 * Makefile.in (VERSION): Set to 4.1.
1070 * language.c (set_language_command): Print useful help message,
1071 and restore the language string after giving help.
1072 * valprint.c (typedef_print): Print typedef in C or M2.
1073 * symtab.c (list_symbols): Use it.
1074 * main.c (main): Avoid any output before (gdb) prompt when -q.
1075 * language.c (set_language_command): Handle errors by restoring
1076 the language string to its current state (fix from A. Beers).
1077 * doc/gdbint.texinfo: Roll in information from README. Rearrange
1078 "how to install" and "how to print the doc" stuff so it drops
1080 * configure.in: Rename rtpc CPU to romp to match config.sub.
1081 * README, WHATS.NEW, TODO: Update for gdb-4.1.
1083 Fri Sep 20 17:39:14 1991 Roland H. Pesch (pesch at cygnus.com)
1085 * doc/gdb.texinfo: Updates from ChangeLog. set/show write,
1086 autoloading shared libs, copyright etc on GDB startup, clean up $_
1087 and $__ index refs, set/show listsize and related updates to list
1088 cmd. New host/target configs.
1090 Fri Sep 20 15:46:00 1991 Roland H. Pesch (pesch at cygnus.com)
1092 * doc/Makefile: generate aux version-no file doc/gdbVN.m4
1093 from main Makefile.in version definition
1094 doc/gdb.texinfo: use version recorded in doc/gdbVN.m4 for current
1096 Makefile.in (setup-to-dist): generate doc/gdbVN.m4
1098 * doc/gdb.texinfo: merge new language-switching and lang-specific
1101 Fri Sep 20 15:00:57 1991 Per Bothner (bothner at cygnus.com)
1103 * mcheck.c: Add __ONEFILE kludge to allow compilation by non-ANSI
1104 compilers (which may lack stddef.h).
1106 Fri Sep 20 13:29:42 1991 John Gilmore (gnu at cygnus.com)
1108 * dbxread.c (read_dbx_symtab, process_one_symbol): N_FN and
1109 N_WARNING are the same except for the N_EXT bit, so just use their
1110 values alone, rather than OR-ing them with N_EXT.
1112 Fri Sep 20 12:27:55 1991 Stu Grossman (grossman at cygnus.com)
1114 * mipsread.c (parse_lines): Deal with negative extended line
1117 * c-exp.y, m2-exp.y: #define yyerrflag and yynerrs to avoid
1118 global symbol conflicts.
1120 Fri Sep 20 02:28:15 1991 John Gilmore (gnu at cygnus.com)
1122 * .gdbinit: Move 'set complaints' to top, so it runs even in
1123 case we aren't debugging GDB.
1124 * language.c (_initialize_language): Fix type check and range
1125 check documentation strings.
1126 * utils.c (!HAVE_VPRINTF): Define vfprintf as a function, so
1127 language.c can use it. (Though language.c should really not be
1128 handling warnings/errors the way it does, FIXME.)
1129 * symtab.c (lookup_primitive_type): const lint.
1131 Bugfix from Peter Schauer:
1132 * source.c (lines_to_list): Make signed, to avoid comparison
1133 going unsigned and complaining that -3 is too high for 21 lines.
1134 * stack.c (lines_to_list): Ditto.
1136 Thu Sep 19 23:33:41 1991 John Gilmore (gnu at cygnus.com)
1138 * Makefile.in (HFILES): Add minimon.h.
1139 (VERSION): Roll version number to 4.0.95.
1140 (gdb.tar.Z, make-proto-gdb.dir, setup-to-dist, gdb-XXX.tar.Z):
1141 New rules for building distributions. Normal distribution
1142 is built by doing `make -f Makefile.in gdb.tar.Z' in the directory
1143 one level up from here; it calls make-proto-gdb.dir to build a
1144 directory `proto-gdb' which is an image of the release. The old
1145 `gdb.tar.Z' rule still works too.
1146 * config.sub, configure: Roll in latest from ..
1148 Thu Sep 19 17:41:24 1991 Roland H. Pesch (pesch at cygnus.com)
1150 * doc/gdbint.texinfo: Reorder contents; reorganize new-host,
1151 new-target, and new-config chapters; fix minor typos; come closer
1152 to usual GNU markup conventions for @file @samp @code @var.
1154 Thu Sep 19 17:04:12 1991 Per Bothner (bothner at cygnus.com)
1156 Patches from Peter Schauer <pes@regent.e-technik.tu-muenchen.de>:
1157 * mipsread.c (parse_partial_symbols): Enter the name of all
1158 structs/unions... into the psymtab so we can access them if the
1159 symtab is not read in.
1160 * mips-tdep.c: Remove some unneeded #includes.
1161 * xconfig/dec3100: Add HAVE_STRSTR.
1163 Thu Sep 19 15:14:23 1991 John Gilmore (gnu at cygnus.com)
1165 * Makefile.in: Circumvent Sun Make bug on *-exp.tab.o.
1166 * c-exp.y, m2-exp.y: Lint.
1167 * m2-exp.y: Avoid using yytname[] which is a Bison-ism.
1168 * valprint.c (val_print_fields): Check for stub type.
1169 * mipsread.c (_initialize_mipsread): Avoid using
1170 builtin_type_void at initialize time.

1173 Wed Sep 18 15:55:51 1991 John Gilmore (gnu at cygnus.com)
1175 Merge multiple-language support, and partial Modula-2 support,
1176 from Andrew Beers <beers@cs.buffalo.edu>.
1178 * i387-tdep.c: New file, consolidates most 80387 support,
1179 and eliminates host dependency on double<->extended conversions.
1180 * i386-xdep.c, symm-xdep.c: Remove most 387 support.

1198 (process_coff_symbol): #if 0'd for functions and params as above.
1199 (read_enum_type): Recognize Modula-2 BOOLEAN.
1200 * symtab.c (add_param_to_type): #if 0'd function to add a

1205 source.c, symfile.c, dbxread.c, breakpoint.c, core.c, exec.c,
1206 i387-tdep.c, infcmd.c, mips-tdep.c, stack.c, printcmd.c: Output
1207 hex with local_hex_string for Modula-2 support.
1209 * breakpoint.c (breakpoint_cond_eval): Use new value_true to test

1212 * parse.c: New file with the common code remains of expread.y.
1213 * parser-defs.h: New file with common declarations from expread.y.

1236 TYPE_CODE_BOOL and TYPE_CODE_CHAR.
1238 * expression.h (enum exp_opcode): Add Modula-2 specific opcodes.
1239 * expprint.c: Look up expression opcodes in language-specific

1272 Tue Sep 17 08:37:41 1991 John Gilmore (gnu at cygint.cygnus.com)
1274 Add Andrew Beers' changes for Modula-2 support. His ChangeLog
1275 entries are enclosed herein. Not all of these changes
1276 have been merged into the master GDB sources -- check the
1277 ChangeLog above here for the merge log.
1279 Mon Jun 3 17:05:45 EDT 1991
1281 m2-exp.y Created. Tested outside of GDB for a few days. Proper
1282 operators were added, C specific operators and tokens
1283 removed. yylex() revamped to some extent. Still things
1284 missing from the grammar, such as sets.
1285 Tested for two weeks in GDB v3.5.
1287 Tue Jun 11 17:23:48 EDT 1991
1289 m2-exp.y Added boolean constants TRUE and FALSE to the grammar
1290 so they are built-in. Sort of a hack.
1292 Fri Jun 14 12:53:51 EDT 1991
1294 m2-exp.y Added range checking for numeric constants. Any numeric
1295 constant is assumed to be of builtin type INTEGER unless:
1296 (1) it is octal or hexadecimal, in which case it is a
1297 CARDINAL; (2) it is too big to fit into an INTEGER, in
1298 which case it is a CARDINAL.
1299 eval.c Added simple range checking for +, -, and * on integers.
1300 Doesn't work very well for *, since 6 * 1,000,000,000 =
1301 1,705,032,704, which fails the simple test of result >=
1302 first_operand, no matter in what order the operands are.
1304 Tue Jun 18 14:11:30 EDT 1991
1306 Broke the parser into parts, one containing the C grammar and the other
1307 containing code to be shared by all of the grammars.
1309 The following files no longer exist:
1314 The following files were added:
1316 c-exp.y (The C grammar)
1317 m2-exp.y (The Modula-2 grammar)
1318 parser-code.c (Code that is shared by the above grammar)
1322 Makefile.dist Changed to reflect the above dependencies. NOTE: It is
1323 now necessary to use the Bison compiler compiler, since it
1324 will generate function/variable prefixes other than yy.
1326 Tue Jun 18 16:47:49 EDT 1991
1328 symtab.[ch] Added the external variable working_lang, than holds the
1329 value of the current working language.
1330 Added the ennumerated type language_mode, with the values
1331 language_auto and language_manual, the former meaning that
1332 GDB sets working_lang as needed, and the latter meaning
1333 that the value of working_lang is totally under user
1335 symtab.[ch] Added the Modula-2 pervasive types INTEGER, CARDINAL,
1336 REAL, BOOLEAN and CHAR. Also added the type codes
1337 TYPE_CODE_BOOL and TYPE_CODE_CHAR.
1338 utils.c Added set_language_command and show_language_command to
1339 implement the GDB support commands "set language" and
1341 expression.h A number of identifiers were added to the type exp_opcode
1342 to facilitate Modula-2 builtin functions, integer
1343 division, and array indexing.
1345 Wed Jun 19 13:25:58 EDT 1991
1347 language.h Added the macro STRICT_TYPE, which evaluates to non-zero
1348 if the language specified by working_lang requires the use
1349 of strict typing of expressions. Eventually, even this
1350 will be able to be changed by the user.
1351 Added the macro RANGE_CHECK, which evaluates to non-zero
1352 if the language specified by working_lang requires the
1353 checking of a value against the domain of its type.
1354 Eventually, even this will be able to be changed by the
1356 language.[ch] Predicates involving types (simple_type, ordered_type,
1357 same_type, integral_type, numeric_type, character_type,
1358 boolean_type, float_type) are added. These predicates are
1359 based on the current value of working_lang, and are handy
1362 Wed Jun 19 15:39:34 EDT 1991
1364 eval.c Added the function type_array_rank which computes the rank
1366 valarith.c Added the funtion value_bool, which when given a integer
1367 value.h value (ie. struct value *) as an argument, it returns a
1368 boolean value (ie. struct value *) true if that integer
1369 is non-zero, and a boolean value false otherwise.
1370 valprint.c Added cases for TYPE_CODE_BOOL, so Modula-2 BOOLEAN values
1371 will print out properly.
1373 Wed Jun 19 16:36:34 EDT 1991
1375 valops.c Added the function value_capitalize, which returns it
1376 value.h argument capitalized if its argument is a lowercase
1377 letter, or the argument unchanged if its argument is not a
1379 valarith.c Added the function range_check_p, which returns non-zero
1380 value.h if its value argument is between the integral bounds upper
1382 Added the function range_check_enum_p, which makes sure
1383 that its value argument is a valid member of the domain of
1385 Added the function range_check_range_p, which makes sure
1386 its value argument lies between the upper and lower bounds
1387 of its type argument, which must be a ranged type.
1388 Added the function check_array_index, which range and type
1389 checks an index of an array.
1390 Added the function value_multi_subscript, which computes
1391 array[idx1,idx2...idxN], given a value array and an array
1392 of values representing indicies.
1393 values.c Changed value_from_long to work with TYPE_CODE_CHAR and
1394 unpack_long to work with TYPE_CODE_BOOL and
1397 Wed Jun 19 18:04:08 EDT 1991
1399 symtab.c Stored pervasive types in a structure and make
1400 lookup_pervasive_type() a lookup function that was based
1401 on working_lang. If lookup_pervasive_type() returned
1402 non-zero, then that value was returned (a fix, since
1403 before it simply wouldn't return the pervasive type.)
1404 language.h Added the macro CAST_IS_CONVERSION, which evaluates to
1405 non-zero if the language specified by working_lang means
1406 "conversion" when it says "cast".
1407 valops.c Added the function value_real_cast(), which performs a
1408 value.h *cast*, not a *conversion*, which is what value_cast()
1409 does when it can. In particular,
1410 value_cast(<float_type>,4) = 4.0, while
1411 value_real_cast(<float_type>,4) = some mess.
1412 eval.c Modula-2 builtin functions implemented: ABS, CAP, CHR,
1413 parser-code.c FLOAT, HIGH, MAX, MIN, ODD, ORD, TRUNC, and VAL.
1414 expression.h Added macros MAX_OF_TYPE and MIN_OF_TYPE to work with MAX
1415 and MIN on integral types. *NOTE*: These are currently
1416 hardcoded to work only if there are 8 bits per storage
1418 eval.c Made logical functions call value_bool to return a
1419 properly typed boolean value, based on working_lang.
1421 Thu Jun 20 11:55:27 EDT 1991
1423 valprint.c Types now print out in a Modula-2 fashion. This works for
1424 the cases when the type is printed out step-by-step, that
1425 is, it doesn't work when the name of a structured type
1426 (which includes the keyword "struct", etc.) is simply
1428 FIXME: Perhaps this is bad. Parts of it seem to kludgey,
1429 since type specifications in C and Modula-2 are very
1430 different. The C printing of a type is very recursive,
1431 whereas in Modula-2 it is generally very simple. C has
1432 type prefixes and suffixes, which have no real analogue in
1433 Modula-2. Maybe type_print() should call a language
1434 specific type printer. This is also advantageous if we
1435 compile GDB to exclude some of the languages. We'll just
1436 leave those functions out.
1438 Thu Jun 20 16:57:10 EDT 1991
1440 dbxread.c When reading the complete symbol table in (via
1441 psymtab_to_symtab()), the number and types of function
1442 arguments are added to a function type. define_symbol()
1443 calls add_param_to_type() to accomplish this.
1444 Assumption: when we come across a function definition
1445 (N_FUN symbol with an 'f' or 'F' in the name), its
1446 arguments will appear before another function definition.
1447 When a function is found, a pointer to its type is placed
1448 in the global in_function_type. Changes that
1449 add_param_to_type() makes are to this global.
1450 valprint.c The type of a function now includes (for Modula-2) the
1451 types of its parameters.
1452 eval.c Type checking and a check for the proper number of
1453 arguments is now done for function calls. Not sure of the
1454 impact this has on C++ member function yet.
1456 Thu Jun 20 19:58:48 EDT 1991
1458 valprint.c Rewrote the type printer. Broke it into two language
1459 specific parts, adding the functions type_print_m2() and
1461 An unfortunate consequence is this: if you debugging a C
1462 program in Modula-2 mode (why?), info types does not work
1463 well with regular expressions, since the types are printed
1464 out in Modula-2 terminology, but stored in C terminology.
1465 language.[ch] Added the functions new_type_last(), type_keyword(), and
1466 type_sep() to aid in the printing of typedefs.
1467 symtab.c Made the printing of typedefs as language independent as
1468 possible through calls to new_type_last(), type_keyword(),
1471 Fri Jun 21 11:50:26 EDT 1991
1473 dbxread.c Check all incoming ennumerated types. If it looks like
1474 Modula-2's BOOLEAN type, then change the type_code of the
1475 type to TYPE_CODE_BOOL so we can process it as a boolean
1477 valprint.c Replaced some of the 0x%x with calls to sprintf and
1478 hexformat() in val_print().
1479 language.[ch] Added the function hex_to_string(), which converts its
1480 integral argument to a hexadecimal number (format is
1481 language based) and returns the result as a string.
1483 Mon Jun 24 12:25:07 EDT 1991
1485 valprint.c Some functions call type_print_1() directly, instead of
1486 value.h using type_print(), so they can specify where (column) to
1487 print things. Since type_print() takes care of language
1488 dependence, that needs to be called first. Added a
1489 parameter depth to type_print() (so it is now like
1490 type_print_1). Changed type_print to type_print_at, and
1491 made type_print a macro that passes a depth argument of
1493 symmisc.c Changed all calls to type_print_1 to calls to
1495 Makefile.dist Made it possible to build GDB for a specific set of
1496 depend languages. Do this by passing a definition for the macro
1497 LANGS to make. LANGS should be a string containing a
1498 space-separated list of language names (ie. LANGS="c m2").
1499 The default is to build all languages. Note that grammar
1500 files must follow the naming convention of <lang>-exp.y.
1501 gdb.lang This holds the current value of the LANGS macro. It is
1502 examined every time make is called, and is updated if
1504 eval.c Added #ifdef _LANG_<lang> to these files.
1505 expread.c Still need to add them to dbxread.c and coffread.c.
1513 Mon Jun 24 16:33:11 EDT 1991
1515 language.[ch] Added the functions hexformat_pre() and
1516 hex_to_string_pre(), which take a prefix argument to
1517 include in the format string. Thus, hexformat_pre("08") will
1518 return "0x08x" (if the working language is language_c).
1519 Made hexformat() and hex_to_string() calls to the above
1520 with "" as the prefix argument.
1522 am29k-pinsn.c, arm-pinsn.c, breakpoint.c, convex-tdep.c, exec.c, core.c,
1523 dbxread.c, i386-pinsn.c, i386-stub.c, i386-xdep.c, i960-pinsn.c,
1524 infcmd.c, inflow.c, m68k-pinsn.c, m68k-stub.c, m88k-pinsn.c,
1525 mips-pinsn.c, mips-tdep.c, ns32k-pinsn.c, printcmd.c, pyr-pinsn.c,
1526 pyr-tdep.c, pyr-xdep.c, remote-vx.c, remote.c, solib.c, source.c,
1527 stack.c, sun386-xdep.c, symfile.c, symm-xdep.c, symmisc.c, tahoe-pinsn.c,
1528 valprint.c, vax-pinsn.c
1530 Changed all occurences of 0x%[0-9]*l*x in printf format strings to
1531 calls to hexformat() and hex_to_string(). Format strings without
1532 the leading "0x" were ignored.
1534 depend Updated to take the above into account.
1537 Tue Jun 25 15:27:18 EDT 1991
1539 symtab.h Added the types range_mode_t, range_check_t, type_mode_t,
1540 and type_check_t to keep track of the current state of
1541 range and type checking.
1542 main.c Added the variables range_mode, range_check, type_mode,
1543 and type_check to record the current state of range and
1544 type checking. Added initialization code to main().
1545 language.h Changed the macros STRICT_TYPE and RANGE_CHECK to examine
1546 the above variables.
1549 Tue Jun 25 17:57:08 EDT 1991
1551 dbxread.c process_one_symbol() updates the variable (enum language)
1552 source_lang based on the extension of the filename
1553 contained in the N_SO sybmol that started this symtab.
1554 When end_symtab() is called, the value of source_lang is
1555 put into the language field.
1556 stack.c select_frame() sets working_lang (and possibly type_check
1557 and range_check) to the language field of the symtab
1558 associated with the frame that is selected if working_mode
1559 is language_auto. If working_mode is language_manual, a
1560 warning is printed and working_lang is not set.
1561 language.c Added the function set_type_range(), which sets the value of
1562 type_check and range_check (if their modes call for
1563 automatic setting) based on the current value of
1564 working_lang. A non-zero argument will cause the current
1565 settings to be output.
1568 Wed Jun 26 14:51:40 EDT 1991
1570 eval.c Added range checks on assignment.
1571 m2-exp.y Added the grammar for sets to the language. Currently,
1572 these do not do anything except print an error message.
1574 Wed Jun 26 17:01:04 EDT 1991
1576 m2-exp.y Added the ability for parse_number() to parse negative
1577 numbers. A global flag is set upon encountering a unary
1578 minus. This was done to make, for example, 1 parse as a
1579 CARDINAL, and not as an integer, per Wirth's examples in
1580 Programming in Modula-2 ed.4.
1581 valprint.c Added support for "set radix 2" by then setting
1582 output_format to 't'.
1583 eval.c Implemented range checking on subrange types. Added calls
1584 to range_check_range_p for BINOP_ASSIGN and BINOP_VAL.
1585 Implemented MIN and MAX for ennumerated types. The
1586 minimum value of an ennumerated type is defined by Wirth
1587 as the first identifier, and the maximum as the last.
1588 m2-exp.y Made octal numbers ending with "B" be characters and those
1589 ending with "C" be numbers, per Wirth's book. (p. 34)
1591 Thu Jun 27 14:11:52 EDT 1991
1593 stack.c select_frame() now only sets working_lang, it does not
1594 notify the user. If working_mode is language_manual, then
1595 a warning is issued once.
1596 main.c At the end of each call to execute_command(), working_lang
1597 is checked against the local static (enum language)
1598 current. If they differ and working_mode is
1599 language_auto, the new settings of language, type and
1600 range checking are printed out.
1601 stack.c Modified frame_info() to include the language of the
1602 current frame in the output of "info frame".
1603 language.[ch] Added the function language_str() which returns the name
1604 of the current language.
1606 Fri Jun 28 15:33:14 EDT 1991
1608 m2-exp.y Added the built-in procedures INC, INCL, DEC, and DECL to
1609 the language. INCL and DECL currently cause an error,
1610 since sets are not implemented yet. INC and DEC are
1611 implemented as PREINCREMENT/PREDECREMENT with one
1612 argument, and as ASSIGN_MODIFY with two arguments.
1613 eval.c Added type checking to the above cases.
1614 value.h Added not_lval_constant to the lval_type ennumerated type.
1615 not_lval_constant means that the value is a constant
1616 value; that is 3 or 'a' or TRUE, not as in a constant
1617 identifier. This is used to help coerce numbers such as 3
1618 to either signed or unsigned numbers.
1619 valops.c Added the function value_coerce_constants() which coerces
1620 constant integers as following: if one is a constant and
1621 the other is not, the constant's type is set to the type
1622 of the other argument. If both are constants and one is
1623 signed, the other is converted to a signed constant.
1625 Sat Jun 29 17:26:29 EDT 1991
1627 valarith.c Added a better range checker. It now checks range
1628 (successfully) on integral operations [+-] (signed and
1629 unsigned) for any C sized type. Still does not work well
1630 for multiplication.)
1631 int_in_size() returns an integer that is coerced to fit into
1632 specified number of bytes.
1634 Mon Jul 1 13:04:14 EDT 1991
1636 language.[ch] Added the function binop_result_type(), which returns the
1637 builtin (struct type *) type that would be the result of a
1638 binop on the two values V1 and V2.
1640 Wed Jul 3 19:22:53 EDT 1991
1642 source.c Extended source_info() to include the source language in
1643 the output from "info source".
1645 Fri Jul 5 13:48:52 EDT 1991
1647 utils.c Moved the support functions for the GDB set/show commands
1648 dealing with language into language.c.
1649 language.c Added the function language_info(), which displays info
1650 about the current working language, type and range check
1651 settings. Called via the GDB command "info language".
1652 Added an initialization routine _initialize_language(),
1653 that sets defaults for the language, type and range
1654 variables and sets up the new GDB commands.
1655 main.c Language setup moved to language.c.
1658 Mon Jul 8 10:10:22 EDT 1991
1660 valarith.c Debugged the range checker for arithmetic. Still does not
1661 work for multiplication very well.
1663 Mon Jul 8 12:40:37 EDT 1991
1665 language.[ch] Added the function value_true() which returns non-zero if
1666 its argument represents a boolean true value.
1667 breakpoint.c Changed breakpoint_cond_eval() to call value_true() to
1668 check the truth of an expression.
1670 Thu Jul 11 12:51:34 EDT 1991
1672 language.[ch] Added the predicate structured_type(), which returns
1673 non-zero if the argument is a structured type.
1674 Added the predicate pointer_type(), which returns non-zero
1675 if the argument is a pointer type.
1676 eval.c Added the ability to do addition and substraction on
1677 pointers and integers. This case simply bypasses the
1680 Thu Jul 11 14:41:42 EDT 1991
1683 Added the symbol N_DEFD (0x4a) which is a definition
1684 module dependency that is used by the GNU Modula-2
1685 compiler and the linker. It is not important to GDB,
1686 except that [dbx|coff|mips]read.c should ignore these
1689 Fri Jul 12 16:07:00 EDT 1991
1691 valprint.c Changed the TYPE_LENGTH(type) >= 0 to TYPE_LENGTH(type) >
1692 0 in val_print(). Also added statements to the else part
1693 to coerce type (argument to val_print) to a pointer type
1694 if it is an "array of unspecified length".
1695 valops.c Added the function value_m2_string(), which returns a
1696 (value) value which is a constant string, whose type is
1697 (ARRAY [0..n] OF CHAR). The length field of the type
1698 structure is set to zero, so it will be interpreted as an
1699 "array of unspecified length".
1700 stack.c Moved the language/frame mismatch check to
1701 main.c:execute_command().
1702 main.c The working language is recorded each time
1703 execute_command() is executed. If working lang has
1704 changed during its execution, then the new
1705 language/type/range info is printed out for the user. If
1706 the working language does not match the language of the
1707 frame, a warning is issued.
1709 Sat Jul 13 16:16:39 EDT 1991
1711 eval.c Moved all the type-checking stuff for operators to
1712 language.[ch] language.c. This is so we can keep language-specific
1713 stuff (like for what type operators are defined) in
1715 language.[ch] Added the function binop_type_check(), which checks to see
1716 if its two (value) arguments are type-compatible with its
1717 opcode argument. The opcode should represent an operation
1718 involving an operator. Also added the macro function
1719 unop_type_check, which calls binop_type_check with a
1720 NULL second argument.
1721 expprint.c Added Modula-2 operators to the op_print_tab, so info
1722 expression.h break works correctly. Also added "op_string", which
1723 returns the string corresponding to the (enum exp_opcode)
1724 opcode that is its argument.
1727 Sat Jul 13 18:26:18 EDT 1991
1729 coffread.c Added code to record the type of function arguments with
1730 each paricular function. Code is very similar to that
1732 dbxread.c Moved add_param_to_type() to symtab.c
1733 symtab.[ch] Added function add_param_to_type() from dbxread.c
1735 *** NOTE: The above additions have not been tested.
1737 Mon Jul 15 12:50:47 EDT 1991
1739 langauge.[ch] Added the functions type_error and range_error, which work
1740 like error() except if the type/range mode is set to
1741 *_mode_warn, then they do not do a return_to_top_level(),
1742 but merely print a warning.
1743 Also changed [set|show]_[type|range]_command() to support
1744 the new "warn" feature.
1746 Thu Jul 18 17:50:54 EDT 1991
1748 mipsread.c Added code to record the type of function arguments with
1749 each particular function. Code is very similar to that
1752 *** NOTE: The above additions have not been tested.
1754 Fri Jul 19 11:19:10 EDT 1991
1756 defs.h Added macros MAX_OF_SIZE, MIN_OF_SIZE, UMAX_OF_SIZE, and
1757 UMIN_OF_SIZE, which when given a size of a numeric type,
1758 return the maximum and minimum value it can hold. UMAX...
1759 and UMIN... return the result for unsigned types.
1760 symtab.h Added the macros MAX_OF_TYPE and MIN_OF_TYPE to operate on
1761 struct types. They call above macros.
1762 dbxread.c Renamed the MAX and MIN_OF_TYPE macros to ..._OF_CTYPE to
1763 avoid a name conlict with the above.
1764 c-exp.y Added range checking on numeric constants in
1765 parse_number() for completeness.
1766 valarith.c Made binop_user_defined_p() and unop_user_defined_p()
1767 return 0 if working_lang is not language_c.
1769 Thu Aug 8 14:17:22 EDT 1991
1773 breakpoint.c Documentation strings of some commands changed to
1774 eliminate the references to the C language where
1777 Tue Aug 13 15:48:03 EDT 1991
1779 m2-exp.y Added qualified identifiers to the grammar. The semantics
1780 are slightly different from those of the GDB operator ::
1782 m2-exp.y Added a rule to each grammar of the form: start ::= exp |
1783 type_exp, where type_exp is any valid type expression.
1785 eval.c Added the opcode OP_TYPE, and an error case in eval.c.
1786 printcmd.c Modified ptype_command() so it actually parses the input
1787 (necessary for type expressions with scope qualifiers).
1788 Added the function ptype_eval() which expects an
1789 expression composed of one OP_TYPE element.
1790 *.[ch] Replaced all occurences of parse_c_expression with
1792 *.[ch] Replaced all occurences of parse_c_1 with parse_exp_1
1794 [End of ChangeLog entries from Andrew Beers for Modula-2 support.]
1796 Mon Sep 16 17:19:46 1991 John Gilmore (gnu at cygnus.com)
1798 Small fixes from Peter Schauer:
1800 * infrun.c (child_attach): Lint.
1801 * solib.c (find_solib): Handle shared libs version 2.
1803 Small fixes from David Wood:
1805 * xm-ultra3.h (SYS_SIGLIST_MISSING): Typo.
1809 * remote-vx.c: Move <stdio.h> to top, for FILE. Fix from
1810 John S <basrai%kanga.dnet@c3po.sm-alc.af.mil>.
1812 * utils.c (wrap_here): Avoid wrap action of fputs_filtered if
1813 chars_per_line is at maximum (user typed `set width 0'). Fix
1814 from Andreas Schwab <schwab@ls5.informatik.uni-dortmund.de>.
1816 Tue Sep 17 17:31:04 1991 Stu Grossman (grossman at cygnus.com)
1818 * coredep.c: include ptrace.h where necessary.
1819 * mipsread.c(parse_lines): fix unsigned char problem that was
1820 messing up line numbers on SGI's and possibly other MIPS based
1822 * infrun.c (child_create_inferior): use better test to check
1823 return val from setpgrp().
1824 * tm-irix3.h, xm-irix3.h, tconfig/irix3, xconfig/irix3: add these
1825 for sgi/irix support.
1827 Wed Sep 18 04:33:31 1991 Per Bothner (bothner at cygnus.com)
1829 * mipsread.c (parse_symbol): Put non-static procedures
1830 in the global block.
1832 Fri Sep 13 00:14:52 1991 John Gilmore (gnu at cygnus.com)
1834 Patch together `text_start' and `text_end' for 29K port.
1836 * exec.c (exec_command): If NEED_TEXT_START_END, define the
1837 variables and set them based on the exec file.
1838 * am29k-tdep.c: declare text_start.
1839 * valops.c (call_function_by_hand): declare text_end.
1841 * inferior.h: Eliminate CANNOT_EXECUTE_STACK in favor of
1842 defining CALL_DUMMY_LOCATION as BEFORE_TEXT_END. This is
1843 because machines that do this will also have to know to
1844 set NEED_TEXT_START_END. Besides, it was a redundant way to
1846 * tm-29k.h, tm-convex.h, tm-np1.h: Eliminate
1847 CANNOT_EXECUTE_STACK, define CALL_DUMMY_LOCATION and
1848 NEED_TEXT_START_END.
1850 Thu Sep 12 00:22:24 1991 John Gilmore (gnu at cygint.cygnus.com)
1852 AMD 29000 changes from David Wood <wood@david.ultra.nyu.edu>:
1854 * Makefile.in (CLIBS): Put XM_CLIBS and TM_CLIBS at end.
1855 Pass MUNCH_DEFINE to munch whenever we run it.
1856 * am29k-pinsn.c (print_insn): Handle NOP specially. Avoid %#x
1857 format string; use 0x%x instead.
1858 * am29k-tdep.c: Use DUMMY_SAVE_GREGS and RETURN_REGNUM.
1859 * ultra-xdep.c, xm-ultra.h: New files for Ultracomputer host system.
1860 * xm-rtbsd.h: New host support for RT/PC running BSD Unix.
1861 * inflow.c: Handle `short' process group IDs.
1862 * infptrace.c (fetch_register): Support CANNOT_FETCH_REGISTER,
1863 and check for ptrace errors.
1864 * coffread.c (SDB_REG_TO_REGNUM): Define if not already.
1865 (coff_symfile_init): Initialize text_bfd_scnum.
1866 (read_coff_symtab): Use it to find the text [and absolute?] sections.
1867 * ../config.sub: Add vendor nyu and os "sym[1-9]*".
1868 * configure.in: Add hosts rtpc-*-* and a29k-*-*.
1869 Merge target arm case with other "easy" cases. Add target
1870 cases a29k-*-none (rehack of am29k), a29k-*-kern (remote to
1871 Ultracomputer kernel), and a29k-*-sym1 (ultracomputer OS's user
1873 * minimon.h, remote-adapt.c, remote-mm.c: Add.
1874 * munch: Cope with RT/PC putting fns in data segment.
1875 Restore ability to override `nm' by specifying MUNCH_NM.
1876 * xconfig/rtbsd, xconfig/ultra3: New host systems.
1877 * tconfig/a29k: Rename from tconfig/am29k. Add remote-mm
1878 and remote-adapt. Remove encapsulated coff #define's (the
1879 support should go in BFD, and gdb shouldn't know or care).
1880 * tconfig/a29k-kern: Same, but for remote kernel debugging.
1881 * tconfig/ultra3: For debugging user processes on Ultra3/Sym1.
1882 * tm-29k.h: Update BADMAG (though it should go away).
1883 Allow the register definitions to be overridden in another
1884 tm-file. Fix SR_REGNUM. Add a mess of _REGNUM's. Separate
1885 RETURN_REGNUM from GR96_REGNUM and DUMMY_SAVE_GREGS from
1886 DUMMY_SAVE_GR96, for handling kernel calling conventions
1887 that use GR64+ rather than GR96+.
1888 * tm-ultra3.h: New file, for use on Ultra3 Unix as well as for
1889 remote debugging of Ultra3 kernel. Includes tm-29k.h and
1890 overrides various things.
1892 * remote-mm.c (mm_attach, mm_wait): Handle attach like
1893 child_attach does, making a clean stop in the newly attached
1895 * remote-eb.c: Lint.
1897 * coffread.c: Make coffread independent of any particular
1898 variant of COFF. Avoid #include-ing any particular one except
1899 internalcoff.h. BFD now passes key values for symbol reading
1900 as part of its coff_data structure (LINESZ, SYMESZ, AUXESZ,
1901 and the symbol masks and shifts); use them.
1902 Remove obsolete end_of_text_addr.
1904 * exec.c: Remove unused include files.
1906 Wed Sep 11 19:38:44 1991 John Gilmore (gnu at cygint.cygnus.com)
1908 * Makefile.in (documentation targets): Pass $(M4).
1909 Bugfix from eggert@twinsun.com (Paul Eggert).
1911 * stack.c (down_silently_command): Check for stack existence.
1913 Tue Sep 10 23:08:29 1991 John Gilmore (gnu at cygint.cygnus.com)
1915 * Makefile.in (VERSION): Update to 4.0.3.
1917 Tue Sep 10 09:19:29 1991 John Gilmore (gnu at cygint.cygnus.com)
1919 * core.c (core_file_command): Print frame at coredump with
1920 its level number, by calling print_stack_frame.
1921 * frame.h: Add selected_frame_level, print_stack_frame.
1922 * frame.h, stack.c: Remove print_sel_frame, print_selected_frame.
1923 * convex-tdep.c, convex-xdep.c, infcmd.c, inflow.c, infrun.c:
1924 Change print_sel_frame and print_selected_frame callers to
1927 * dbxread.c (read_ofile_symtab): Avoid empty else clause.
1928 * symfile.c (free_named_symtabs): Ditto.
1929 * main.c (main): wrap_here needs an arg.
1930 * solib.c (find_solib): Avoid memory access if _DYNAMIC is zero.
1931 (solib_add): Avoid noise.
1932 (solib_create_inferior_hook): Lint.
1933 (sharedlibrary_command): Move dont_repeat to here.
1934 * utils.c (error): Call wrap_here to force buffered output.
1936 Small patches from Peter Schauer:
1938 * coffread.c (start_symtab): Free any existing line_vector before
1940 (read_coff_symtab): Ditto for type_vector.
1942 * source.c (lines_to_list): New variable, replacing function.
1943 (all uses): Use as variable.
1944 (_initialize_source): Add 'set listsize' and 'show listsize'.
1945 * utils.c (lines_to_list): Remove function.
1946 * stack.c (print_frame_info): Use as variable.
1947 * defs.h (lines_to_list): Remove declaration.
1949 Mon Sep 9 13:45:57 1991 John Gilmore (gnu at cygint.cygnus.com)
1951 * breakpoint.c (insert_breakpoints): Restore warning about
1952 the program might be running in another process, but only for
1953 systems with this brain death (#ifdef ONE_PROCESS_WRITETEXT).
1954 * xm-hp300bsd.h, xm-mips.h, xm-vax.h: Define it.
1956 * utils.c (error): if error_pre_print is set, print the string
1958 * main.c (main, print_gnu_advertisement, print_gdb_version):
1959 Reformat legalese so it always prints, but acts as an "I'm here"
1960 message while symbols are being read. If any errors occur,
1961 print a few newlines to set off the message and start it at the
1962 left margin. Remove mention of "help" command, and don't yak
1963 about symbol reading.
1964 (catch_errors): Error string is now printed first in case of
1966 * command.c (undef_cmd_error, lookup_cmd): On undefined command,
1967 suggest the "help" command.
1969 * Makefile.in (VERSION): Set to 4.0.2.
1971 Thu Sep 5 23:49:48 1991 John Gilmore (gnu at cygint.cygnus.com)
1973 * .gdbinit: Remove useless "rr" command. Set complaints
1974 to 1 for people debugging gdb.
1976 * breakpoint.c, remote-vx.c: Reword strings printed by
1977 catch_errors callers.
1979 Wed Sep 4 11:07:50 1991 John Gilmore (gnu at cygint.cygnus.com)
1981 * WHATS.NEW: "history write -> history save". Doc "write on/off".
1982 (Fix from kenc@viewlogic.com.)
1984 Fix some infrastructure to be able to cope with host and target
1985 machines with different sized basic types (ints, ptrs, etc).
1986 (Idea from pierre@la.tce.com (Pierre Willard).)
1988 * values.c (value_from_longest): Rename from value_from_long.
1989 Handle pointer types as well as integers, so that targets with
1990 different pointer sizes from the host can be accomodated.
1991 * breakpoint.c, convex-tdep.c, eval.c, expprint.c, printcmd.c,
1992 valarith.c, valops.c, valprint.c, value.h, values.c: Rename
1993 uses of value_from_long to value_from_longest.
1994 * eval.c, findvar.c, printcmd.c, valarith.c, valops.c: Pass
1995 the correct pointer type to value_from_long{est}.
1997 * doc/gdb.texinfo ($_, $__): Describe types of these variables.
1999 * remote-vx.c: Remove obsolete code for calling functions via
2000 vxworks kludge interface (it referenced value_from_long).
2002 * valops.c (value_string): Find malloc with lookup_misc_func, not
2005 Tue Sep 3 18:37:46 1991 John Gilmore (gnu at cygint.cygnus.com)
2007 Make writing to files work properly. (Fixes to BFD are also needed.)
2009 * core.c (core_open): Open file ourselves, read or r/w, depending on
2010 write_files. Use bfd_fdopenr.
2011 * gdbcore.h (write_files): New variable.
2012 * exec.c (write_files): Define variable, add set&show for it.
2013 (exec_file_command): Use write_files to open for read or r/write.
2015 Make shared library reading happen automatically. These changes
2016 are mostly from Peter Schauer <pes@regent.e-technik.tu-muenchen.de>.
2018 * inferior.h (stop_soon_quietly): Add to exported variables.
2019 * infrun.c (child_create_inferior): call solib hook, if defined.
2020 (child_attach): call solib hook, if defined.
2021 * solib.c: Include inferior.h. Add from_tty to so_list as kludge.
2022 (find_solib): Use lookup_misc_func rather than hand-rolled.
2023 (symbol_add_stub): New stub for catch_errors.
2024 (solib_add): Avoid output if !from_tty. Catch errors rather
2025 than just calling symbol_file_add and bombing.
2026 (solib_create_inferior_hook): Interface with the target process
2027 to let it read and alloc shared libs, then figure out what it did.
2029 * core.c (validate_files): Fix typo, soften warning.
2030 (Fix from Hiroto Kagotani <kagotani@cs.titech.ac.jp>.)
2032 * utils.c (fputs_demangled): Avoid duplicate printing if
2033 demangling is off. (Fix from J.T. Conklin <jtc@cayenne.com>.)
2035 * infrun.c (proceed): Cast -1 to (CORE_ADDR) before comparing.
2036 (Fix from pierre@la.tce.com (Pierre Willard).)
2038 * main.c (catch_errors): Change argument to a char * from an int,
2039 since a char * can point to a struct full of glop, but an int
2040 is not guaranteed to be able to hold a pointer.
2041 * breakpoint.c (breakpoint_cond_eval, bpstat_stop_status,
2042 breakpoint_re_set_one, breakpoint_re_set): Adapt.
2043 * core.c (core_open, solib_add_stub): Adapt.
2044 * remote-vx.c (symbol_stub, add_symbol_stub, callers): Adapt.
2046 Wed Aug 28 18:18:05 1991 John Gilmore (gnu at cygint.cygnus.com)
2048 * Makefile.in: Update VERSION to 4.0.1. Evade GNU Make bug
2049 by adding .NOEXPORT target.
2051 Fri Aug 23 17:14:25 1991 John Gilmore (gnu at cygint.cygnus.com)
2055 * Makefile.in (VERSION): Roll to 4.0.
2056 (gdb.tar.Z): Make refcard.ps as well, for shipment.
2058 Fri Aug 23 14:07:09 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
2060 * doc/gdb.texinfo: minor rewordings, crossref to ptype from print,
2063 * doc/Makefile, Makefile.in: generate "gdb-all.texi" rather than
2066 * doc/rdl-apps.texi: renamed from rdl-apps.texinfo
2068 * Makefile.in, doc/Makefile, doc/.Sanitize, doc/gdb.texinfo:
2069 reflect above name change
2071 * WHATS.NEW: correct pointer to refcard.
2073 * doc/gdb.texinfo: update New Features, Installing
2075 * doc/gdbint.texinfo: add short description of configure +template
2077 Fri Aug 23 11:46:08 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
2079 * doc/gdb.texinfo: update, fix bugs in "Installing" appendix
2081 Fri Aug 23 01:02:00 1991 John Gilmore (gnu at cygint.cygnus.com)
2083 * Makefile.in: Add config.sub, make doc/rdl-apps.texinfo for
2084 tar file, add dependencies for referenced doc files.
2086 Thu Aug 22 22:17:06 1991 Stu Grossman (grossman at cygint.cygnus.com)
2088 * coffread.c, symfile.c, stack.c: saberized.
2090 Thu Aug 22 16:20:27 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
2092 * doc/refcard.tex: permuted Essential Commands sec
2094 * doc/gdb.texinfo: new C++ chapter; revised installation appendix;
2096 set/show symbol-reloading
2097 default set complaints 0
2099 RET-repeat disabled after prompted long displays
2100 processID (attach) interpretation of 2nd GDB cmdline arg
2102 Thu Aug 22 14:05:47 1991 Stu Grossman (grossman at cygint.cygnus.com)
2104 * expread.y, coffread.c, dbxread.c, target.c, mem-break.c,
2105 cplus-dem.c, values.c, valprint.c, symfile.c, remote.c,
2106 breakpoint.c, main.c: lint.
2108 Thu Aug 22 02:02:26 1991 John Gilmore (gnu at cygint.cygnus.com)
2110 Install new configuration scheme for GDB and friends.
2112 * config.sub: Translate ordinary names to three-part names.
2113 * configure: Use three-part names internally.
2114 * configure.in: Translate three-part names to filenames.
2116 * README, WHATS.NEW: Update for gdb-4.0.
2117 * Makefile.in: Roll VERSION to 3.99.
2119 Wed Aug 21 18:21:09 1991 John Gilmore (gnu at cygint.cygnus.com)
2121 * infptrace.c (KERNEL_U_ADDR_BSD): Include a.out.gnu.h.
2122 * i960-tdep.c, m68k-tdep.c, sparc-tdep.c, tm-i960.h,
2123 tm-m68k.h, remote-nindy.c: Change ext_format_XXX structs
2124 to single structures rather than arrays; when passing
2125 their address, use &. This avoids trouble with bdead compilers.
2126 * mcheck.c: Don't include <stdlib.h>; just declare "void abort();"
2127 instead. This avoids portability headaches.
2128 * mips-tdep.c (mips_do_registers_info): Only print FP regs if
2130 * source.c (open_source_file): Avoid ANSI const bdeath by
2131 skipping declaration and then casting result value.
2132 * tm-hp300bsd.h: Clarify comment.
2133 * utils.c (strstr): Result is const char *; ANSI bdeath.
2134 * xm-hp300bsd.h: Define HOST_BYTE_ORDER. Redefine INT_MIN,
2135 since system include file defines it differently from "defs.h",
2136 though the two are equivalent for our purposes.
2137 * tconfig/hp300bsd: Add m68k-tdep.o.
2139 Tue Aug 20 16:01:11 1991 John Gilmore (gnu at cygint.cygnus.com)
2141 * tconfig/sun*4: Remove warnings about system assembler.
2143 Mon Aug 19 13:44:46 1991 John Gilmore (gnu at cygint.cygnus.com)
2145 * mcheck.c: Avoid warning about undeclared abort fn.
2146 * tm-sparc.h (PC_ADJUST): Avoid calling error() from this;
2147 it causes recursive calls to error() when used in cleanups.
2148 To do so requires that we make it a function, so we do.
2149 * sparc-tdep.c (sparc_pc_adjust): New implem of PC_ADJUST.
2150 * utils.c (do_cleanups): Remove the current cleanup from the
2151 chain *before* calling it, in case error() is called from it.
2152 The result won't be pretty, but won't be an infinite loop either.
2154 Mon Aug 19 00:41:04 1991 Michael Tiemann (tiemann at cygint.cygnus.com)
2156 * dbxread.c (read_struct_type): Grok anon structs for C++.
2157 (vb_name, vptr_name): Null terminate these strings.
2159 Fri Aug 16 08:31:03 1991 John Gilmore (gnu at cygint.cygnus.com)
2161 Minor bug fixes from BSD Net2 gdb:
2163 * blockframe.c (get_prev_frame_info): If FRAME_CHAIN_COMBINE
2164 returns 0, there is no previous frame.
2165 * breakpoint.c (commands_command): If !from_tty, don't call
2166 input_from_terminal_p().
2167 * dbxread.c (record_misc_function): Speed up slightly.
2168 (compare_psymbols): Ditto.
2169 * infcmd.c (do_registers_info): Take a second argument to
2170 determine whether to print float registers. "info registers"
2171 does not do so anymore. "info all-registers" does, now.
2172 * mips-tdep.c, pyr-tdep.c (xxx_do_registers_info): Take second
2174 * tm-mips.h, tm-pyr.h (DO_REGISTERS_INFO): Pass second arg.
2175 * inflow.c (initialize_inflow): Set tflags_ours correctly.
2179 * breakpoint.c (bpstat_do_actions): Use a cleanup to restore
2180 executing_breakpoint_commands if we are interrupted by error.
2181 * coffread.c (init_lineno): Avoid problem with zero-sized linetab
2182 versus malloc/free. From: john@labtam.labtam.oz.au (John Carey).
2183 * core.c (solib_add_stub, core_open): Call SOLIB_ADD inside a
2184 catch_errors() so we can setup the frame regardless of whether
2185 the shared libs work.
2186 * ieee-float.c (double_to_ieee_extended): Get exponent from
2187 right place in little-endian systems. From John Carey.
2189 Thu Aug 15 18:43:57 1991 John Gilmore (gnu at cygint.cygnus.com)
2191 * main.c: Remove unused terminating_signals and catch_termination().
2192 (long_options): Terminate with a zero element.
2193 [Bugfix from Atsuo Kawaguchi <atsuo@hark86.harl.hitachi.co.jp>.]
2194 (gdb_readline): Make call-compatible with readline.
2195 (init_signals): Improve comments re vfork vs. signal.
2197 * utils.c (prompt_for_continue): Use new gdb_readline().
2198 If we prompt for continuation, we don't let CR repeat the previous
2199 command, once we get back to a prompt. It's too easy to keep
2200 hitting CR, expecting "--more--" prompts, and have some long
2201 command start repeating on you.
2203 Tue Aug 13 16:17:56 1991 John Gilmore (gnu at cygint.cygnus.com)
2205 * blockframe.c (frameless_look_for_prologue): Speed up by
2206 calling SKIP_PROLOGUE_FRAMELESS_P if it's defined.
2207 * tm-sparc.h (SKIP_PROLOGUE, SKIP_PROLOGUE_FRAMELESS_P):
2208 Define two variants, one faster.
2209 * sparc-tdep.c (sparc_frame_chain): Use target_read_memory
2210 and return zero, rather than giving an error.
2211 (setup_arbitrary_frame): Initialize the PC in the new frame.
2212 (skip_prologue): Add a second arg saying whether we're just
2213 checking for a frameless function or not.
2215 * core.c (core_open, core_close, core_xfer_memory): Move
2216 section table pointers and bfd* into the target_ops.
2217 (core_open): Allow errors in shared lib reading, etc.
2218 (core_files_info): Describe shared library sections.
2220 * exec.c (exec_open, exec_close, exec_xfer_memory, xfer_memory,
2221 exec_files_info, set_section_command): Move section table
2222 pointers and bfd* into the target_ops.
2223 (add_to_section_table): Add BFD to section table.
2225 * target.c (target_xfer_memory, target_info): Pass target to
2226 xfer_memory and target_info functions.
2229 * gdbcore.h: Move struct section_table.
2230 * target.h: New home of struct section_table.
2232 * solib.c (solib_add): New argument is the target_ops whose
2233 section list is to be added to, if any. Reallocate the
2234 sections in that target to add any that come from shared libs.
2235 (throughout) so_sections renamed to sections.
2236 (solib_xfer_memory): Deleted.
2237 * tm-sunos.h (SOLIB_ADD): Add target argument.
2238 (SOLIB_XFER_MEMORY): Delete.
2240 * core.c, exec.c, inftarg.c, remote-eb.c, remote-nindy.c,
2241 remote-vx.c, remote.c, target.c, target.h: Remove add_syms vector
2242 from target_ops. It's the same on all targets. Add two section
2243 pointers to target_ops.
2245 * stack.c (find_relative_frame): Dump ancient algorithm for
2246 "down", just use handy "next" pointers.
2247 (frame_command): Don't error if there is no stack; let user
2250 * inflow.c (new_tty_prefork, new_tty): New prefork routine
2251 modifies static state in the parent process; new_tty itself
2252 runs in the child and modifies the child's file descriptors
2253 to match the saved static state.
2254 * infrun.c (child_create_inferior): Call new_tty_prefork,
2257 * infptrace.c (child_xfer_memory): Add ignored target arg.
2258 * remote-eb.c (eb_xfer_inferior_memory): ''
2259 * remote-nindy.c (nindy_xfer_inferior_memory): ''
2260 * remote-vx.c (vx_xfer_memory): ''
2261 * remote.c (remote_xfer_memory): ''. Rename from
2262 remote_xfer_inferior_memory.
2264 * main.c (main): Only try to attach "corefile" argument if
2265 it starts with a digit.
2267 * symfile.c (symbol_reloading): New "set/show" variable.
2268 (symbol_file_add): Shorten message about symbol reading.
2269 (add_symbol_file_command): Merge with add_syms_addr_command,
2270 since this should work on all targets now.
2271 (stop_whining): Default to zero, to shut up complaints
2272 about bad symbol tables on many systems.
2273 (free_named_symtabs): Just exit unless symbol_reloading.
2275 * xm-sun3os4.h, xm-sun4os4.h: Define BROKEN_LARGE_ALLOCA,
2276 and add comment explaining shared library screw.
2278 * source.c: #if defined => #ifdef.
2280 Thu Aug 8 12:23:19 1991 John Gilmore (gnu at cygint.cygnus.com)
2282 * doc/gdbint.texinfo: Improve doc on porting to new OS's.
2284 Tue Aug 6 17:16:15 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
2286 * doc/rdl-apps.texinfo: provide default readline-appendix finder
2287 (doc/Makefile knows how to make one for local config)
2289 * Makefile.in: use doc/Makefile for doc targets
2291 * doc/Makefile: GDB documentation now has its own Makefile
2292 doc/refcard.tex: renamed from "gdbrc.tex"
2293 doc/.Sanitize: add Makefile; recognize renamed refcard.tex
2294 doc/gdbint.texinfo: add markup in "Cleanups" chapter
2297 Fri Aug 2 00:13:06 1991 John Gilmore (gnu at cygint.cygnus.com)
2299 * values.c (baseclass_addr): When reading target memory, use the
2300 length of the basetype, not the upper type. We've only malloc'd
2301 enough space for the basetype, leading to errors in free().
2303 * expprint.c (print_subexp): Print UNOP_MEMVAL of an OP_LONG that
2304 ends up as a function specially, since we know the actual type of
2305 the pointed-to address. This (somewhat) fixes display of
2306 expressions that include misc_function_vector names. Try `cond 1
2307 !strcmp("a","b")' then `i b'.
2309 * infrun.c: Move DO_DEFERRED_STORES from proceed() to resume().
2310 The child can be proceeded from inside wait_for_inferior in
2311 evaluating breakpoint conditions, and DO_DEFERRED_STORES was
2312 getting skipped in that case.
2314 * expprint.c (print_subexp): Use filtered output, since the
2315 subroutines we call use it, otherwise the output is horribly
2316 mangled, since output of wrappable stuff comes out late.
2318 * Makefile.in: Bump VERSION to 3.98.1
2320 * infrun.c (child_create_process): Use execlp to find the
2321 shell to exec our target program. This requires some fiddling
2322 with `environ' since there is no execlpe().
2324 Thu Aug 1 15:35:17 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
2326 * Makefile.in, doc/gdbrc.tex, doc/rc-* (new files):
2327 Minor rearrangement of refcard permits two new make targets--
2328 gdbrc.dvi DVI output for refcard, using CM fonts
2329 gdbrc.ps PostScript refcard, using PS fonts
2331 Wed Jul 31 16:46:21 1991 John Gilmore (gnu at cygint.cygnus.com)
2335 * TODO, Projects, WHATS.NEW, README: Update for gdb-3.98.
2336 * Makefile.in (gdb-all.texinfo): Avoid touching file if M4 dies.
2338 Wed Jul 31 16:35:58 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
2340 * doc/gdb.texinfo: last changes for release.
2341 Minor typo and formatting fixes; incorporated most fixes remaining from
2342 filed mail commenting on earlier drafts.
2344 Added warnings: pipes don't work in run command;
2345 conditions are converse of assertions;
2346 step over fn without debug info goes to next fn;
2347 vars may have "wrong" values near fn entrance, exit
2349 Added example from Kingston on printing repeated nonadjacent values
2351 Added explicit mention that in Emacs gdb mode C-c and C-z are like
2352 shell mode for signals
2354 Renamed "Stepping and Continuing" to "Continuing and Stepping" so it
2355 doesn't sound so much like its parent "Stopping and Continuing"; also
2356 moved entries on continue to top of section, so they don't get lost.
2358 Improved installation directions in appendix, added manual formatting
2361 Tue Jul 30 17:26:39 1991 John Gilmore (gnu at cygint.cygnus.com)
2363 * configure.in: Remove xm.h and tm.h even if we aren't linking
2364 new ones, so "./configure sun4; ./configure none" does the right
2365 thing. Assume that alldeps.mak and depend are already built in
2366 srcdir, and avoid running "make" (particularly "make depend",
2367 which involves "gcc") from inside configure. Build Makefile
2368 directly rather than building Makefile.conf first.
2369 * configure: Regenerate with above changes.
2370 * Makefile.in: Use $(BISON) to find bison. Roll VERSION
2371 to 3.98. Revise gdb.tar.Z procedure to produce a file
2372 called gdb-$(VERSION).tar.Z but which unpacks into a
2373 directory called "gdb". Move non-source files out of
2374 $(SFILES_SUBDIR). Pretty up alldeps.mak with comments.
2375 (depend): Don't try to do "gcc expread.y".
2376 (expread.o): Update dependencies by hand.
2378 Mon Jul 29 15:21:09 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
2381 Fixed a variety of small typos that prevented info from formatting
2382 cleanly; altered too-long heading for GPL Appendix, as discussed
2383 w/RMS; Changed date on cover to July 91.
2385 Fri Jul 26 13:20:02 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
2388 (1) Applied some fixes due to comments from Larry Breed (easier ones
2389 through chapsec 5.2)
2390 (2) Eliminated use of @footnote---had my doubts about it anyways, and
2391 it's broken in latest texinfo
2392 (3) Introduced *some* use of [] for optional arguments, where
2393 explanation is not simpler by listing cmd w arg and cmd w/out arg
2394 separately. Still not using @deffn.
2395 (4) Dropped in GPL-2. NOTE: one of GPL-2 or texinfo is broken; a
2396 couple of headings are too long. Need patches to texinfo or revision
2399 * Partial update to README (which still needs work for this
2400 release!): (1) use of configure corrected for new script,
2401 (2) "make gdb.dvi" and "make gdb.info" mentioned.
2403 Wed Jul 24 06:44:02 1991 John Gilmore (gnu at cygint.cygnus.com)
2405 * symtab.c (lookup_symbol): Don't complain right off about
2406 no debug symbols; use the misc function vector first.
2407 (list_symbols): Use misc function vector to find symbols
2408 that don't have debug info, and print them.
2409 (find_pc_symtab): Temporarily avoid fatal() when psymtab
2410 PC range doesn't match symtab PC range, as it does on the
2411 MIPS because our symtab reading isn't perfect.
2413 * dbxread.c (dbx_symfile_read): Make warning about
2414 "no debug symbols" slightly nicer.
2416 * source.c (select_source_symtab): If "main" symbol exists,
2417 but decode_line_spec can't find line info, don't just return
2418 a zero; try other source symtabs or give an error.
2420 * mipsread.c (parse_partial_symbols): Sort the psymtabs by
2421 their low addresses first, then rip through fixing high addrs.
2423 * ns32k-opcode.h (sfsr): Bugfix from Rune Nerg}rd,
2424 <runene@ifi.uio.no>.
2425 (NS32K_SVC_IMMED_OPERANDS): Reverse the #ifndef.
2427 Tue Jul 23 18:52:43 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
2429 * Minor, mostly mechanical, cleanup of doc subdir for clean
2430 makeinfo'ing and TeXing; also ensured gdb-all.texinfo (post-m4)
2431 and gdb.info (post- texinfo2 makeinfo) generated for distribution.
2433 Sun Jul 21 03:54:52 1991 John Gilmore (gnu at cygint.cygnus.com)
2435 Mostly MIPS and general symbol-reading fixups.
2437 * doc/gdbint.texinfo: Add documentation on symbol-reading
2440 * mipsread.c: Remove kludges around #include "ecoff.h".
2441 Remove redefinitions of a_magic, etc, no longer used.
2442 (parse_symbol, ): Convert "Internal:" printfs to complain()ts.
2443 Fix global overview comments to match symfile.c protocol.
2444 (mipscoff_new_init): Eliminate cur_hdr if we have one.
2445 (mipscoff_symfile_read): Eliminate unused code. Avoid
2446 sorting all the symtabs, when all we have read here is psymtabs.
2447 The symtabs are sorted as they are created anyway. Tell
2448 condense_misc_bunches whether we're mainline.
2449 (psymtab_to_symtab_1): Pass filename when recursing, to make
2450 stack trace more informative.
2451 (parse_partial_symbols): Assume cur_hdr as argument.
2452 (read_mips_symtab): Don't clobber cur_hdr, so it can be freed.
2453 Pass cur_hdr implicitly to parse_partial_symbols. Avoid checking
2454 the TYPE_NAME of char *, since that's done in symfile.c.
2455 (free_numargs, parse_symbol, add_symbol, add_block,
2456 shrink_linetable): Declare these fns void.
2457 (upgrade_type): Convert tree of if's to switch. Clean up
2458 bogus "off == 0" handling with a complaint. Avoid setting
2459 field bitpos and bitsize of array with lower and upper bounds.
2460 Check specified bitsize of elements against their actual type's
2461 bitsize, and complain if different. Complain about unknown
2463 (parse_fdr): Don't assume sizeof(char *) == sizeof (struct *).
2464 (psymtab_to_symtab_1): Print names of subsidiary files that
2465 are being read in. FIXME, we read far too many files. This code
2466 is not the problem, the problem is in parse_fdr where the psymtabs
2468 (cross_ref): Result should indicate that we used one aux entry
2469 normally, or two if we encountered a "next" entry. This used
2470 to leave the caller pointing at the wrong aux entry.
2471 (add_symbol): If overflowed cur_block, reallocate it larger,
2472 chase all pointers to it, and complain(), rather than clobber memory.
2473 (shrink_block): Use xrealloc rather than xmalloc-and-copy.
2474 (new_field): Only allocate one field initially, not two.
2475 Pull ++ out of macro argument. Simplify.
2476 (_initialize_mipsread): Avoid initialization of importd
2477 global_psymbols and static_psymbols.
2479 * symfile.c (psymtab_to_symtab): Depend on XXX_psymtab_to_symtab
2480 to properly set pst->symtab; avoid searching for it.
2481 (symfile_fns): Improve comments, add a FIXME.
2482 * dbxread.c: Update comments to reflect symfile protocol.
2483 (read_ofile_symtab, end_symtab): Return the symtab.
2484 (psymtab_to_symtab_1): Set pst->symtab.
2486 * coffread.c (coff_symfile_read): tell condense_misc_bunches
2487 whether we're mainline.
2489 * symfile.h (sym_fns): Remove unused sym_discard member.
2490 * coffread.c, mipsread.c, dbxread.c: Remove XXX_symfile_discard.
2492 * mtrace.c (mtrace): Take effect if mallwatch is set, even if
2493 the environment variable is not.
2494 * infcmd.c (finish_command): Use filtered printfs.
2495 * cplus-dem.c: Add struct tags to a few unnamed structs.
2496 * valops.c (value_coerce_array): Improve comments.
2497 * valprint.c (type_print_varspec_suffix): Print array size only
2498 if greater than zero.
2499 * m88k-tdep.c: Shift some lines left by one space, that had
2500 apparently been trashed at some point.
2501 * TODO: More things to do, a few got done.
2503 Thu Jul 18 22:46:05 1991 John Gilmore (gnu at cygint.cygnus.com)
2505 * symtab.h (LOC_EXTERNAL): Eliminate in favor of LOC_STATIC.
2506 (ldsymoff, ldsymlen, globals_offset, statics_offset): Improve
2508 * dbxread.c (read_dbx_symtab): LOC_EXTERNAL -> LOC_STATIC.
2509 * expread.y, findvar.c, symmisc.c: Ditto.
2510 * printcmd.c (address_info): Update printed forms of LOC_
2511 symbols. Elim LOC_EXTERNAL.
2512 (print_frame_args): Keep track of param stack offsets before
2513 re-looking up to find the local register param is kept in.
2515 * mipsread.c: Use <symconst.h> and <sym.h> rather than <syms.h>.
2516 Further integration of mipsread into gdb. Eliminate unused
2517 routines, duplicate declarations. Handle static symbols in
2518 psymtabs as well as external symbols. When reading symtabs,
2519 insert symbols into the correct block (global, static, or a local
2521 (read_mips_symtab, parse_partial_symbols): Don't pass useless
2523 (mipscoff_symfile_read): Don't call select_source_symtab.
2524 (parse_symbol): Use SYMBOL_VALUE_ADDRESS where appropriate,
2525 rather than SYMBOL_VALUE.
2526 (parse_external): Comment clobbering of top_stack.
2527 (parse_partial_symbols): Update comments. Allocate and parse
2528 static symbols as well as external symbols. FIXME, enum values
2529 are not handled in this pass, but should be. Inline new_psymbol.
2530 Use SYMBOL_VALUE_ADDRESS.
2531 (psymtab_to_symtab_1): Read symbols into global static block
2532 by default (until enter some function's local block context).
2533 (sort_blocks): Clean up STATIC_BLOCK as well as GLOBAL_BLOCK.
2534 (destroy_all_symtabs, new_psymbol): Eliminate, unused.
2536 * source.c (select_source_symtab): Select a source symtab
2537 from either the symtabs or, failing that, the psymtabs.
2538 (list_command): Update error message.
2539 (forward_search_command, reverse_search_command): Use getc, not
2540 fgetc, for speed. FIXME, add comment about buffers that die if
2541 overrun by long line.
2543 * values.c (unpack_field_as_long, modify_field): Avoid shifting
2544 by an entire word, which is not portable, if we have a 32-bit
2545 field. (Code in dbxread.c already turns such bitfields, if
2546 aligned, into ordinary ints, but fixing this will help for other
2547 symbol formats and for future changes.)
2548 * core.c (core_open): Handle ANSI const brain death.
2549 * utils.c (vprintf): Fix varargs typo.
2551 Sun Jul 14 00:42:53 1991 John Gilmore (gnu at cygint.cygnus.com)
2553 * findvar.c (find_var_value): Handle &function better.
2554 * TODO: Document work needed on &fn and &array.
2555 * printcmd.c (print_address_symbolic): New arg is the prefix
2556 to print if a name is printed.
2557 (print_address_demangle): Honor "set print address" now.
2558 Use new arg above to improve spacing of output.
2559 * valprint.c (val_print): When printing function pointers,
2560 print symbolic form too.
2561 * breakpoint.c (breakpoint_1): Use new print_address_symbolic.
2563 Mon Jul 8 19:02:46 1991 John Gilmore (gnu at cygint.cygnus.com)
2565 * core.c (memory_error): Reword error msg to mislead less.
2567 * mips-pinsn.c (print_insn_arg 'd'): Print $ with reg name.
2569 * mipsread.c (read_mips_symtab, read_the_mips_symtab,
2570 parse_partial_symbols): Use newer BFD internals (external_filehdr
2571 and external_aouthdr), byte-swap the fields that we care about
2572 before using them, and make the file header data local to
2573 read_the_mips_symtab rather than global.
2575 Sat Jul 6 01:34:15 1991 John Gilmore (gnu at cygint.cygnus.com)
2577 * ns32k-opcode.h (movmw, movmd): Fix opcodes. Bug fix
2578 from Rune Nerg}rd <runene@ifi.uio.no> on 5 Jul 1991.
2580 * main.c (command_line_input): Flush stdout and stderr
2581 before every call to readline. This reportedly fixes a bug
2582 that comes up in Sys V running emacs-gdb and/or xxgdb,
2583 when stdin/out are pipes or sockets.
2585 Thu Jul 4 14:47:06 1991 John Gilmore (gnu at cygint.cygnus.com)
2587 * configure.in, Makefile.in: Avoid rebuilding "depend" as much.
2588 Avoid declaring Makefile dependencies, because GNU Make stupidly
2589 tries to update it if we do.
2591 * coffread.c: Revise for minor changes to bfd internal coff
2594 * configure: If -template= is given a relative path, make it
2595 absolute before recurring in subdirectories.
2597 * configure, configure.in, Makefile.in: Install "configure" script
2598 as replacement for config.gdb.
2599 * config.gdb, Makefile.dist, Makefile.sdir: Remove
2600 * README: Update for configure, mostly. FIXME.
2602 * Add dec3100 as equivalent to littlemips. Indicate in all host &
2603 target config files that they are for the host. When the lines
2604 get copied into the Makefile, this makes it more obvious what's
2607 Mon Jun 24 23:49:07 1991 John Gilmore (gnu at cygint.cygnus.com)
2609 * sparc-opcode.h (trap opcodes): Avoid leading spaces or
2610 tabs, which end up in the disassembler output inadvertently.
2612 Wed May 29 23:01:03 1991 John Gilmore (gnu at cygint.cygnus.com)
2614 Make it compile cleanly in an ANSI GCC2 environment.
2616 * blockframe.c: <stdio.h>
2617 * cplus-dem.c: free takes a void *, ifdef __STDC__
2618 * dbxread.c (read_huge_number): avoid gcc2 bug hoisting calc of
2620 * defs.h (alloca): Avoid doing anything if alloca already def'd.
2621 * stddef.h, stdlib.h: Remove these files.
2622 * symtab.c: Avoid declaring qsort, close.
2623 * symfile.c: Avoid declaring close.
2624 * utils.c (vprintf): Declare "ap" arg as proper va_alist.
2625 * sparc-tdep.c: Avoid including lots of Sun-host-specific files.
2627 Assorted other changes.
2628 * dbxread.c: include "libaout.h", not "liba.out.h".
2629 * printcmd.c (print_frame_args): Set recurse properly for
2630 indentation of struct and array parameters.
2631 * valops.c (value_cast): Allow cast to void.
2632 * infrun.c (resume): If NO_SINGLE_STEP, call machine dependent
2633 single_step() in a target-independent fashion.
2634 * sparc-tdep.c (single_step): Don't call ptrace ourselves, just
2635 set up to be ready to continue. This makes us target independent.
2636 * infptrace.c (child_resume): Remove call to single_step; now
2637 can single step a SPARC target of any kind.
2639 Wed May 22 18:18:24 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
2641 * Makefile.dist, doc/gdb.texinfo, doc/*-m4.texinfo: split up GDB
2642 docn into separate sections---basically chapters, plus two loose
2643 pieces that can be configured to go in different places. This
2644 allows GNU m4 to preprocess the manual without coredumping.
2646 * Makefile.dist: tell TeX where to find texinfo.
2648 Mon May 20 12:15:04 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
2650 * Makefile.dist, doc/gdb.texinfo: respectively create, and use,
2651 the new target "rdl-apps.texinfo" which captures the Makefile
2652 variable that records where to find the Readline libraries.
2654 Sun May 19 05:36:59 1991 John Gilmore (gnu at cygint.cygnus.com)
2656 * tahoe-pinsn.c: #include "tahoe-opcode.h", not "opcode.h".
2657 * tm-tahoe.h (FIX_CALL_DUMMY): Ignore more parameters.
2658 * defs.h (const, volatile): Only define if not already defined.
2659 * Makefile.dist (gdb.tar.Z): Create doc subdir w/out CVS/RCS crud.
2661 * README: Update for release 3.95.
2662 * config.gdb: Don't create readline dir in subdir builds.
2663 * main.c: Include with "..." form for non-system include files,
2664 so "gcc -MM" for "make depend" works.
2665 Include readline files with "...h" rather than <readline/...h>.
2666 * mipsread.c: Include "ecoff.h" rather than "intel-coff.h".
2668 * coffread.c: Undo minor damage done by Rich Pixley. Use
2669 different internal and external representations of COFF
2670 data structures. Use new BFD routines for swapping them in and
2672 * symfile.c (free_named_symtabs): Avoid freeing file names that
2673 are null or empty. Old i960 tools seem to produce files that
2674 claim to have empty names, causing each successive file read
2675 to blow away the previous one.
2676 * sparc-xdep.c (deferred_stores): Repair minor damage by Rich.
2677 Move deferred_stores to top of file, but don't separate its
2678 #define's from its variable. Add commentary.
2679 * Makefile.dist: Fix Rich damage; undo "configure" changes in
2680 favor of keeping the (working) config.gdb. Move readline
2683 Fri May 17 12:49:56 1991 Per Bothner (via gnu at cygint.cygnus.com)
2685 * dbxread.c (read_struct_type): Try to handle g++ version 1 MI
2687 * infptrace.c (fetch_registers): no result, since now void.
2688 * tconfig/news: target depends on m68k-tdep too.
2690 Fri May 17 14:40:14 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
2692 * Makefile.dist: added readline/inc-*.texinfo to dependencies for
2695 * readline/inc-history.texinfo, readline/inc-readline.texinfo:
2696 applied various small fixes due to or inspired by RMS comments
2698 * doc/gdb.texinfo: finished using all RMS comments, save those for
2699 appendices on readline and cmd history (which are in other source
2702 Thu May 16 18:06:05 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
2704 * doc/gdb.texinfo: (1) Updated w/ref to RMS comments through
2705 chapter 9; (2) documented 'break' command's menu mode for
2706 overloaded names, in response to hgs problem report C++ p-31
2708 Wed May 15 11:02:48 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
2710 * doc/gdb.texinfo: (1) better introductory example; (2) more
2711 consistent use of @code, @samp, @file, @kbd throughout; small
2712 cleanups to first three nodes; (3) new "Contributors" node;
2713 (4) Appendix, Renamed Commands; (5) divert specialized startup
2714 instructions to "Targets" chapter for generic manuals, while
2715 leaving them up front for manuals specific to specialized
2716 environments; (6) apply fixes from RMS comments through chapter 4.
2718 * pretex.m4: modify explanatory text slightly (and redefine
2719 "regexp") to keep GNU m4 from complaining. (It still crashes
2720 later, but one step at a time...)
2722 Wed May 15 10:32:12 1991 John Gilmore (gnu at cygint.cygnus.com)
2724 * readline/readline.c (update_line): Avoid dereferencing a pointer
2725 before comparing it to its bounds. Saber caught this.
2726 (init_terminal_io): Don't set BC from the "pc=" termcap variable,
2727 and only set PC if tgetstr returned non-null. Saber caught this.
2729 Tue May 14 16:29:53 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)
2731 * Makefile.dist: put gdb.dvi stuff (updated to use M4 preprocessor
2732 stuff for config manual) here where it counts; updated
2733 to use new subdir structure (gdb/doc/).
2735 * Makefile: generated from above via
2739 * gdbint.texinfo: added instructions on generating gdb.info* files
2740 locally for release. These are ordinary info
2741 files, formatted from gdb.texinfo (via gdb-all.texinfo, see
2742 Makefile)---but due to use of texinfo 2, can't count on makeinfo
2743 to generate these, so we distribute them already formatted.
2745 * gdb.texinfo: included full Info node and menu crud (as generated
2746 by C-u M-x texinfo-master-menu using the texinfo-2 elisp code).
2748 * Makefile: updated "gdb.dvi" target to use M4 preprocessor;
2749 put in comments-for-future gdb.info target (one day makeinfo will
2752 Tue May 14 13:51:36 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)
2754 * gdb.texinfo: Updated to include new or old undocumented
2755 commands, at least the following (perhaps some others I forgot to
2756 record): info f, info float, info path, info program, info s, info
2757 set, info source, info terminal, info types, info user, set/show
2759 Also covered all recent GDB command renames for v4.
2761 Mon May 13 14:57:46 1991 John Gilmore (gnu at cygint.cygnus.com)
2763 * mipsread.c: Rather than keeping count of how many symtabs
2764 and psymtabs we have, for sorting purposes, count them when
2765 we need to sort. This fixes bug in rereading of symbol tables.
2767 Fri May 10 15:43:33 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)
2769 * infcmd.c: renamed "info path" to "show paths"
2770 * gdbrc.tex: documented above.
2772 Wed May 8 04:51:11 1991 John Gilmore (gnu at cygint.cygnus.com)
2774 * remote.c: Fix comments.

2777 Sat May 4 11:11:07 1991 John Gilmore (gnu at cygint.cygnus.com)
2779 * Makefile.dist: Roll VERSION to 3.95.
2780 Fix up "saber_gdb" to work again.
2781 * saber.suppress: Update.
2783 * coffread.c, exec.c, infptrace.c, inftarg.c, remote.c, solib.c,
2784 symtab.h, target.c, target.h: Lint.
2785 * core.c: setup and select frame after reading shared libs,
2786 else reading shared libs will clobber them. Lint.
2787 * utils.c (error): Force out any buffered wrap text.
2789 Fri May 3 22:01:56 1991 John Gilmore (gnu at cygint.cygnus.com)
2791 * remote.c: Remove decls of memory_insert_breakpoint
2792 and memory_remove_breakpoint, no longer used. (Suggestion of
2795 * Makefile.dist: use ${subdir} in paths of BFD and LIBIBERTY,
2796 to make it easier to interface to "configure"'d libraries.
2798 Fri May 3 13:10:01 PDT 1991 Roland Pesch (pesch at fowanton.cygnus.com)
2800 * valprint.c: introduce "set p", "set pr", "show p" and "show pr" as
2801 aliases for set/show print.
2803 Thu May 2 11:22:02 1991 Jim Kingdon (kingdon at cygint.cygnus.com)

2843 * {x,t}config/m88k ({X,T}DEPFILES): Add missing files.
2845 * mtrace.c: Don't typedef things like size_t, just #define them.
2847 * coffread.c [TDESC]: #if 0 out references to coffsyn.
2849 * symtab.h (struct symtab): Include EXTRA_SYMTAB_INFO.
2850 tm-88k.h: Define EXTRA_SYMTAB_INFO.

2853 dc_dcontext_t not int.
2855 * coffread.c [TDESC]: Use system include files not <intel-coff.h>.
2857 * coffread.c [TDESC]: Move setting of debug_info from
2858 coff_symfile_read to find_linenos and make it work with BFD.
2860 * cplus-dem.c [__STDC__]: Make x{m,re}alloc return void*.
2862 * signame.c: Cast const char* to char* when assigning to sys_siglist.
2864 * utils.c (strsave): Make arg const char* not char*.
2866 * infrun.c (wait_for_inferior) [SHIFT_INSN_REGS]: Use
2867 bpstat_explains_signal (stop_bpstat) not stop_breakpoint.

2885 Thu May 2 17:53:56 1991 John Gilmore (gnu at cygint.cygnus.com)
2887 Mips bringup and general cleanup
2889 * cplus-dem.c: Move CPLUS_MARKER define to after defs.h.
2890 * infptrace.c (PT_WRITE_D, PT_READ_D): Use correct values.
2891 (This still doesn't seem to make MIPS bkpts work.)
2892 * mipsread.c: Remove dup "Reading symbol data..." msg.
2893 (symbol_file_command, add_file_command): Remove, obsol.
2894 * printcmd.c (ptype_command): Say "an enum" rather than "a enum".
2895 Wrap output appropriately.
2896 * stack.c (locals_info, catch_info, args_info): Check
2897 selected_frame rather than target_has_stack or coredumping.
2898 * valprint.c (type_print_varspec_suffix): Wrap "ptype" output of
2899 enums appropriately.
2901 Wed May 1 14:10:22 1991 Jim Kingdon (kingdon at cygint.cygnus.com)
2903 * signame.c: Include defs.h and param.h.

3374 * dbxread.c (end_symtab): Ditto.
3375 * expread.y (block): Ditto.
3376 * mipsread.c (throughout): Ditto.
3377 * symmisc.c (free_named_symtabs): Ditto.
3379 * symtab.c (list_symbols): Process the first symbol of the
3380 static psymbols list.
3381 (types_info): Restore this function from its untimely #if 0.
3382 It's not perfect, but it is better than nothing.
3383 (_initialize_symtab): Restore "info types".
3385 Thu Apr 11 05:23:19 1991 John Gilmore (gnu at cygint.cygnus.com)
3387 * m68k-stub.c: Remote stub for 680x0's, created from
3388 rem-m68k.shar (which is removed).
3389 * nindy-share/{Makefile,Onindy.c,blout.h,env.h,nindy.c,ttyflush.c}:
3390 Remove RCS log stuff now that we use CVS and it blows our diffs.
3392 Wed Apr 10 14:18:06 1991 John Gilmore (gnu at cygint.cygnus.com)
3394 * symmisc.c (free_named_symtab): Make it work, in its current
3395 kludgy fashion. Change result to indicate if we blew away bkpts.
3396 * dbxread.c (end_symtab): Accumulate result from
3397 free_named_symtab and print warning if we blew user's state.
3398 * symfile.h: free_named_symtab now returns an int.
3400 Mon Apr 8 23:57:43 1991 John Gilmore (gnu at cygint.cygnus.com)
3402 * dbxread.c (dbx_symfile_read): Initialize psymbol list if this
3403 is the first symbol read, even if not mainline.
3404 (dbx_psymtab_to_symtab): symfile might be zero, cope.
3405 * exec.c (exec_ops): Add_syms_addr is valid in our tvec.
3406 (set_section_command): New command ("section xxx yyy" -- should
3407 be renamed to "set section xxx yyy" FIXME) which sets the
3408 base address of a section of the exec file, overriding the
3409 virtual address that BFD reports.
3411 Fri Apr 5 17:14:39 1991 John Gilmore (gnu at cygint.cygnus.com)
3413 * exec.c: Add add_syms_addr_command to exec_ops, so you can
3414 load symbols at any address while examining an exec file.
3416 Thu Apr 4 10:09:35 1991 John Gilmore (gnu at cygint.cygnus.com)
3418 * tm-i386v.h (FLOAT_INFO): Don't define it, since the code
3419 for printing the float info is host-dependent, not
3420 target-dependent. FIXME.
3421 * i386-pinsn.c: Move #includes to top, remove useless ones.
3422 * i386-tdep.c: Don't bother including <.../reg.h> since we
3423 don't use it (and it doesn't exist on host systems).
3425 * ieee-float.c (ieee_extended_to_double): Convert NaN to Inf.
3426 Convert negative numbers properly.
3427 (ieee_test): Make numbers really random; fix format arg.
3429 * infcmd.c (attach_command, detach_command): Don't repeat on CR.
3430 * core.c (core_detach): Unpush core_ops, which might not be on
3431 top. We used to just pop the top, which broke things. Don't
3432 need dont_repeat() any more.
3433 (core_file_command): Psst! Don't repeat it.
3434 * remote-nindy.c (nindy_detach): Don't need dont_repeat() now.
3435 * expprint.c (print_subexp): Avoid switch fallthru on
3436 BINOP_ASSIGN_MODIFY, so we can print += and such.
3437 * frame.h: Fix typo.
3438 * inflow.c (kill_command): After killing inferior, print our
3439 current frame in the core file, if we have one.
3440 (generic_mourn_inferior): When inferior dies, either select
3441 the current frame (in the new target, e.g. core file), or
3442 set both the current and selected frames to NULL.
3444 Changes from Peter Schauer.
3446 * infptrace.c: Avoid <sys/ptrace.h> on USG.
3448 * Make all file names fit in 14 characters (sigh and damn!):
3449 mv hp300hpux-xdep.c hp300ux-xdep.c
3450 mv symmetry-xdep.c symm-xdep.c
3451 mv symmetry-tdep.c symm-tdep.c
3452 mv convex-opcode.h convx-opcode.h
3453 mv tm-vxworks960.h tm-vx960.h
3454 mv tm-vxworks68.h tm-vx68.h
3455 mv Makefile.srcdir Makefile.sdir
3456 mv gdb-int.texinfo gdbint.texinfo
3457 mv remote-sa.m68k.shar rem-m68k.shar
3458 mv remote-multi.shar rem-multi.shar
3459 * Makefile.dist, README, config.gdb, convex-pinsn.c,
3460 tconfig/symmetry, tconfig/vxworks960, tconfig/vxworks68,
3461 xconfig/hp300hpux, xconfig/symmetry: Change names to shorter
3464 * command.c (user_info_1, user_info): New command for listing
3465 the user-defined commands.
3467 Wed Apr 3 15:00:26 1991 John Gilmore (gnu at cygint.cygnus.com)
3469 * dbxread.c (really_free_pendings): Clear file_symbols
3470 and global_symbols after freeing them; otherwise, running
3471 this function twice (if it appears twice on the cleanup
3472 chain), we try to free things twice.
3474 * dbxread.c (read_dbx_symtab): Calculate end_of_text_addr
3475 based on text_addr (the address of text in core), not on addr (the
3476 offset between text in the .o file and in core). This change
3477 is from Peter Schauer.
3479 * main.c: Define ALL_CLEANUPS as a cast of zero.
3480 (return_to_top_level): Use it.
3481 (main): Do all cleanups after each command run as part
3482 of the gdb startup sequence. Also do all cleanups before
3483 entering the command loop, and every time we exit the command
3484 loop and reenter. Before, the cleanups from the startup sequence
3485 were being left undone until the first error!
3486 (command_loop): Rename do_nothing cleanup to command_loop_marker
3487 so we can see it easily when examining the cleanup chain.
3488 (init_signals): Add another do_nothing for signal handling.
3489 (quit_command): Only try to kill target if it has execution.
3490 Problems in the target stack got us into a state where
3491 inferior_pid was nonzero but none of the targets had execution.
3492 In this state you couldn't exit gdb.
3494 * dbxread.c: Two changes from Peter Schauer.
3495 (echo_command): Fflush output after an echo command.
3496 (show_history): Pass all args to cmd_show_list.
3498 * utils.c (init_malloc): Call mtrace to turn on tracing
3499 if the environment variable MALLOC_TRACE is set to a file name.
3500 * mtrace.c: Add source file which provides a log of every malloc,
3501 free, and realloc to a trace file.
3502 * mtrace.awk: Add source file which analyzes the trace file.
3503 * Makefile.dist (GNU_MALLOC, MALLOCSRC): Add mtrace.{c,o,awk}.
3504 (VERSION): Roll to 3.94.3.
3506 * breakpoint.c (breakpoint_1): Add a space to "i watch" output.
3507 (check_duplicates): Don't bother with watchpoints.
3508 (set_raw_breakpoint): Comment about danger of this routine.
3509 (watch_command): Parse and eval all args before calling
3512 * solib.c (find_solib): Avoid error in referencing memory to
3513 see if any more shared libraries have been added. This is
3514 particularly useful if the target has terminated. Bug reported
3517 Changes from Peter Schauer <pesrem@regent.e-technik.tu-muenchen.de>
3518 in bringing up 3.94.2 on the Sun-3.
3520 * Makefile.dist: Include CFLAGS in rule for cplus-dem.o.
3521 * breakpoint.c (enable_breakpoint): Check for valid watchpoint
3522 expression (in scope) before reenabling watchpoint.
3523 * signame.c (init_sigs): Add missing declaration of i, fix
3524 sys_siglist declaration.
3525 * source.c (list_command): Fixed range computation to use
3527 * stack.c (backtrace_command): Do not allow command if target has
3528 no stack, print informative error message.
3529 * target.c (target_command): Do not write into command line
3530 because this fails if the target command is used in a user defined
3531 command. [This change was enhanced by gnu to support any-
3532 unique-prefix matching on target names.]
3533 * valops.c (value_struct_elt): Avoid infinite loop on an
3534 erroneous attempt to print the member of function (try p main.p).
3536 Mon Apr 1 17:05:45 1991 John Gilmore (gnu at cygint.cygnus.com)
3538 * expread.y (name_no_typename): Avoid reduce/reduce errors
3539 caused by ambiguity in handling NAME_OR_INT and NAME_OR_UINT.
3540 Since the GDB parser really doesn't use name_no_typename in a
3541 name-only context, the parser can't tell the diff between
3542 names and numbers here. Avoid allowing a name_no_typename
3543 to be a NAME_OR_*INT to resolve the conflict.
3545 Sun Mar 31 20:12:07 1991 John Gilmore (gnu at cygint.cygnus.com)
3547 Bugfixes from Mark Fox (markf@wrs.com) (test=testField.c):
3549 * valprint.c (val_print_fields): bitfield printing didn't handle
3550 byte order. Indirect through a few more fns to cope.
3552 * values.c (modify_field): also cope with byte order.
3554 Sat Mar 23 10:02:21 1991 John Gilmore (gnu at cygint.cygnus.com)
3556 Cleanup for release 3.94.2:
3558 * Makefile.dist: Pull REMOTE_OBS. Fix saber includes for BFD
3559 include files. Roll version to 3.94.2.
3561 * coffread.c (init_stringtab): Read length into unsigned char
3562 array before swapping; don't assume 32-bit longs.
3564 * target.c (target_info): Don't bother with get_sym_file, just use
3565 the symfile global variable.
3566 * symtab.h, symfile.c (get_sym_file): Delete it.
3568 * dbxread.c (dbx_symfile_init): Don't depend on long == 4 bytes.
3569 (define_symbol): Set symbol line number to 0 if not gcc-compiled.
3570 (read_type): Replace one more error() with complain().
3572 * mipsread.c (parse_partial_symbols): Replace printf with complain.
3574 * i960-tdep.c: Fix copyright attribution.
3576 * config.gdb: Quote all backquotes in doublequotes. You can
3577 quote me on that. BSD 4.4 shell found this one.
3579 * infptrace.c (throughout): The third argument to ptrace is an
3582 * infrun.c (wait_for_inferior): When program has terminated, we
3583 have to call target_terminal_ours before we pop that target off
3584 the stack (e.g. before a call to target_kill or
3585 target_mourn_inferior). This fixes problem where a program
3586 terminates, then GDB stops for (tty output) and you have to type
3587 "fg" to the shell to resume it. FIXME: This code for what to
3588 do after termination really should be in normal_stop instead.
3590 * gdbcore.h (read_memory_check): Change declaration; it changed
3593 * terminal.h: Include <sgtty.h> before <sys/ioctl.h>, since in BSD
3594 4.4 prereleases, this avoids a bug in their sgtty compatability
3596 * remote.c: Use terminal.h rather than hand-rolling the same.
3598 * signame.c, signame.h (psignal): Arg is unsigned, not int.
3599 * utils.c (strsave, strstr): Fix arg types.
3600 * valprint.c (val_print): lint
3602 MIPS symbol table support from Per Bothner:
3604 * symfile.c (symtab_fns): Remove initializer table that needs to
3605 be hacked for each new symbol file format supported.
3606 (add_symtab_fns): New function, chains symbol table
3607 handlers into the global list.
3608 (symfile_init): Search this list.
3609 * symfile.h: Add next pointer, declare add_symtab_fns.
3610 * coffread.c (_initialize_coffread): Call add_symtab_fns.
3611 * dbxread.c (_initialize_dbxread): Call add_symtab_fns.
3613 * mipsread.c (psymtab_to_symtab_1): return void instead of (struct
3614 symbol *). Thus, we no longer need the hack to trash
3615 pst->filename. Good, since that hack confused code in symfile.c!
3617 (reorder_symtabs, destroy_all_symtabs): Removed static
3618 all_symtabs, which was used to qsort symtabs in reorder_symtabs.
3619 Instead, the latter now uses a temporary array (stack-allocated
3620 from an obstack, and then freed).
3622 (parse_symbol): Added a hack to fix up BLOCK_{START,END} if they
3623 haven't been set in the outermost stBlock of a procedure. This was
3624 a problem with f77 binaries on Ultrix 4.?.
3626 (new_symtab, new_symbol, new_type): Continue changing code to use
3627 obstacks more and otherwise conform to dbxread internal style.
3628 Made the free_code of symtabs be free_linetable (as in dbxread)
3629 instead of free_contents. This implies memory leaks when reading
3630 a new symbol table, until the conversion is finished. Did change
3631 (struct symbol) and (struct type) to be allocated on the
3632 symbol_obstack. Blocks and blockvectors are among the things
3635 * mipsread.c (parse_partial_symbols, parse_fdr): It hasn't been
3636 tested much, but it solved one problem (reported by Meissner), and
3637 cleans up some other things. The problem happened when an
3638 included file contains actual code (functions) and not just
3639 definitions. The mips coff is a little inconvenient there, since
3640 it may cause a procedure to be mapped to the wrong psymtab.
3642 * mips-tdep.c (heuristic_proc_desc): Minor cleanup.
3643 * mips-xdep.c (fetch_core_registers): Minor cleanup. FIXME,
3644 this will need work for the new core paradigm.
3646 Opcode patches from the net:
3648 * mips-opcode.h: fix incorrect disassembly of the mfc1, cfc1, and
3649 ctc1 instructions. Also, the cvt.d.w and cvt.s.w instructions were
3650 missing altogether - they are added here. From Bruce Bauman.
3651 * mips-opcode.h: The low mask for C0 instructions was too small.
3652 From Garrett Lau. I modified the fix to check the entire 32-bit
3655 * ns32k-opcode.h: Fix opcodes for deiw and deid. From Bruce
3658 Thu Mar 21 12:56:46 1991 John Gilmore (gnu at cygint.cygnus.com)
3660 Roll in changes from Per Bothner (Tue, 25 Sep 90 11:11:04):
3662 * dbxread.c (read_type): Pointer subtraction (value_sub in
3663 valarith.c) sometimes failed because the types of the
3664 pointers being subtracted were not identical.
3665 These differed because dbxread.c was allocating pointer types
3666 using dbx_alloc_type+smash_to_pointer_type instead of
3667 lookup_pointer_type. I failed to find a justification for the
3668 former, so I changed it to use the latter. Similarly, I
3669 replaced smash_to_function_type by lookup_function_type,
3670 and smash_to_reference_type by lookup_reference_type.
3672 * mipsread.c (parse_symbol, upgrade_type, parse_procedure,
3673 _initialize_mipsread): corresponding changes.
3675 * symtab.c (smash_to_{pointer,reference,function}_type): eliminate.
3677 * source.c (mod_path): Do tilde_expand on each component of the path,
3678 rather than on the (list of) paths as a whole.
3679 (print_source_lines): Set first_line_listed in addition to
3680 current_source_symtab and current_source_line. If the source was
3681 not findable, after a "dir" command to fix the problem,
3682 a "list" would get the wrong lines.
3684 While I was there... (gnu):
3686 * dbxread.c (read_type): Change error to complaint.
3688 Thu Mar 21 12:56:46 1991 John Gilmore (gnu at cygint.cygnus.com)
3690 First attempt at detailed understanding of symbol table memory alloc.
3692 * dbxread.c (dbx_symfile_read): Free our string table if we
3693 aren't the mainline. Free the "info" struct since we're done with
3695 (init_psymbol_list): Free any previously allocated psymbol lists.
3696 (): FIXME: Should realloc-down the psymbol lists when done reading
3697 the main symbol file?
3699 * symmisc.c (free_symtab): Free fullname field too.
3701 * xm-hp300hpux.h (USG): #undef then #define so Makefile can -D.
3702 (REGISTER_ADDR): Make result type unsigned int.
3704 * xconfig/{i386*,hp300hpux,altosgas,altos}: All config files that
3705 define REGEX must also define REGEX1 (its dependency).
3707 Tue Mar 19 21:28:57 1991 John Gilmore (gnu at cygint.cygnus.com)
3709 * tconfig/i960: No longer works, points you at vxworks960 or
3712 * xgdb.c, XGDB-README: Remove file. Users can get the much
3714 * Makefile.dist: Remove all trace of xgdb.
3716 * breakpoint.c (breakpoint_1): Pass demangle arg to
3717 print_address_symbolic.
3718 (clear_breakpoints): Remove unused function.
3719 (breakpoint_re_set_one): Guts of breakpoint_re_set.
3720 (breakpoint_re_set): Use catch_errors to do them all anyway.
3722 * gdb-int.texinfo (Host versus Target): Add section on what is
3723 a "host" feature versus what is a "target" feature.
3725 * infcmd.c (path_command, path_info): Handle the PATH variable
3726 (object search path) as conveniently as the source search path.
3727 * environ.c (set_in_environ): Set some vars in GDB's environment,
3728 in addition to the child's. PATH, G960BASE, G960BIN for starters.
3729 * source.c (mod_path): New function, from guts of
3730 directory_command, modifies a path. Used by path_command.
3731 (directory_command): Call it.
3732 * defs.h (strsave): Declare.
3734 * utils.c (sevenbit_strings): Add new printing option.
3735 (printchar): Use it.
3736 (strsave): Provide this handy helper routine.
3737 (set_width_command): Rename set_screen_width_command.
3738 (_initialize_utils): "set screen-width" => "set width";
3739 "set screen-height" => "set height"; add sevenbit-strings.
3741 * infcmd.c (do_registers_info): Print floating point registers
3742 in raw hex as well as float format, regardless of whether it is
3743 a "virtual" convertible register.
3744 * tm-sparc.h (PRINT_REGISTER_HOOK): Print every pair of float
3745 regs as a double, just in case it's being used that way.
3746 * values.c (unpack_long): Comment on array/function coercion.
3747 (unpack_double): Argument is in target byte order now. For
3748 integer arguments, just call unpack_long and float the result.
3749 * m68k-tdep.c: include defs.h for "const" handling.
3750 * remote-nindy.c: Use ieee-float stuff.
3751 (nindy_fetch_registers): Unpack double regs to host double, then
3753 (nindy_store_registers): Pack extendeds to host double, flip
3754 around by misusing unpack_double, send as target double.
3756 * tm-vxworks68.h (FRAME_CHAIN): Handle current frame pointer of
3757 zero, as when stopped at the first instruction of a process.
3759 * blockframe.c: Fix filename in comment (param.h => tm.h).
3760 * sparc-tdep.c (skip_prologue): More explicit nudging comments.
3761 * tm-68k.h: Fix typos.
3763 Fri Mar 15 01:09:34 1991 John Gilmore (gnu at cygint.cygnus.com)
3765 Changes from a bringup on the DEC Vax under Ultrix 4.0.
3767 * coredep.c (fetch_core_registers): Pass end-address of register
3768 section to register_addr as expected. Don't call supply_register
3769 if we'd just pass it garbage.
3771 * dbxread.c (read_dbx_symtab): Skip N_NSYMS on Ultrix.
3773 * exec.c (xfer_memory): Use boolean xfer_fn result, not int.
3775 * target.c (push_target, target_info): Cast enums to int for < or
3778 * stack.c (print_frame_info): Identify source file & line
3779 even if we can't print it.
3781 * xm-vax.h (MISSING_VPRINTF): No longer missing in Ultrix V4.0.
3783 Sat Mar 9 10:08:20 1991 John Gilmore (gnu at cygint.cygnus.com)
3785 Clean up IEEE floating point support.
3787 * ieee-float.h: New file.
3788 * ieee-float.c: Write real routines to convert between host
3789 doubles and various target IEEE extendeds.
3790 * m68k-xdep.c: Eliminate assembler code for extended floats.
3791 * xconfig/{3b1,altos,altosgas,hp300bsd,isi,news,news1000,sun2os3,
3792 sun2os4,sun3,sun3os3,sun3os4}: Eliminate use of m68k-xdep.o.
3793 * tm-i960.h, tm-68k.h (REGISTER_CONVERT_TO_VIRTUAL,
3794 REGISTER_CONVERT_TO_RAW): Use ieee_extended_to_double and
3795 double_to_ieee_extended.
3796 * i960-tdep.c: Define ext_format_i960.
3797 * m68k-tdep.c: Define ext_format_68881.
3798 * sparc-tdep.c: Define ext_format_sparc, though unused.
3799 * Makefile.dist (HFILES): Add ieee-float.h.
3800 * inftarg.c: #include "ieee-float.h" for the REGISTER_CONVERT
3803 Obsolete the "coffstrip" program in favor of using BFD's strip.
3805 * nindy-share/coffstrip.c: Remove file.
3806 * nindy-share/nindy.c (coffstrip): Routine to run bfd_strip.
3807 * Makefile.dist: Remove references to nindy-share/coffstrip.c.
3808 * tconfig/nindy960: Remove reference to coffstrip.o.
3810 * Makefile.dist: Roll version number to 3.94.1 (not yet final).
3812 Wed Mar 6 09:56:45 1991 John Gilmore (gnu at cygint.cygnus.com)
3814 * symfile.h: Add symfile_bfd, common between dbxread and coffread.
3815 * dbxread.c: Remove static symfile_bfd.
3816 * infcmd.c (do_registers_info): Add PRINT_REGISTER_HOOK, though
3818 * inftarg.c (child_detach): Pop the child_ops vector if the
3819 detach is successful.
3820 * remote-nindy.c (nindy_create_inferior): Don't push a new
3821 nindy_ops since nindy uses the same one for execution and memory
3823 * core.c (core_ops): Use child_attach and child_create_inferior
3824 rather than default attach and create_inferior functions.
3826 Handle floating point registers in core files.
3828 * sparc-xdep.c (fetch_core_registers): Rewrite for float support.
3829 * sun3-xdep.c (fetch_core_registers): Rewrite for float support.
3830 This version untested since BFD doesn't yet support sun3 core
3832 * hp300hpux-xdep.c: Rewrite fetch_core_registers to new calling
3833 conventions. Fix comments and style. This version has not
3834 been compiled yet, since we have no HP inhouse.
3835 * core.c (get_core_registers): Look for two sections, ".reg"
3836 and ".reg2", and pass both to fetch_core_registers sequentially.
3838 Revise directory path yet again.
3840 * source.c (forget_cached_source_info): Not static any more.
3841 (init_source_path): New default source path is "$cdir:$cwd".
3842 (dir_command): Handle variable arguments ($cdir, $cwd).
3843 (source_info): Print "Compilation directory" rather than
3844 "Originally compiled in" to remind people of $cdir.
3845 (openp): If the path contains $cwd, use current directory.
3846 (open_source_file): If compilation directory is known, replace
3847 first $cdir in path with the compilation directory.
3848 (print_source_lines): Even if we can't print the lines, set the
3849 current symtab and line for future commands like "info source" or
3850 "breakpoint". Also, error message now contains the file name,
3851 line number, and file access error message.
3852 (_initialize_source): Fix help text to describe changes.
3853 * main.c (cd_command): Forget cached source info when we chdir.
3854 * utils.c (strstr): Add simple implementation.
3856 Tue Mar 5 01:41:40 1991 John Gilmore (gnu at fowanton.cygnus.com)
3858 * coffread.c (read_one_sym, init_linetable, init_stringtab):
3859 Byte-swap COFF symbol tables if necessary when reading them in.
3860 Use complain() to replace error message in one spot. Needs
3861 corresponding change in bfd/coff-code.h to make some symbol
3862 swapping routines non-static.
3864 Mon Mar 4 00:53:40 1991 John Gilmore (gnu at cygint.cygnus.com)
3866 Merge changes from Eirik Fuller, for UTek.
3868 * defs.h (errno): Add declaration.
3869 * altos-xdep.c, arm-xdep.c, convex-xdep.c, gould-xdep.c,
3870 hp300hpux-xdep.c, infrun.c, inflow.c, infptrace.c, i386-tdep.c,
3871 i386-xdep.c, pyr-xdep.c, mips-xdep.c, remote-eb.c, remote-nindy.c,
3872 remote-vx.c, source.c, standalone.c, stuff.c, sun386-xdep.c,
3873 symmetry-tdep.c, symmetry-xdep.c, umax-xdep.c, utils.c: Eliminate
3874 declarations of errno.
3876 * remote-eb.c: Define B19200 and B38400 as EXTA and EXTB.
3878 * remote-vx.c: Include <sys/time.h> for UTek; Sun gets it via
3879 <rpc/rpc.h> and <rpc/types.h>.
3881 Sat Mar 2 15:47:55 1991 John Gilmore (gnu at cygint.cygnus.com)
3883 * i960-tdep.c (examine_prologue): Add new argument limit,
3884 which stops the scan at the end of the prologue, or at the PC.
3885 This fixes a problem where it walks down into the code for the
3886 user's statements if that code looks like function prologues.
3887 Mark Fox and I have been bouncing this code back and forth, making
3888 small changes to it. Callers changed to match.
3890 Tue Feb 26 01:47:07 1991 Cygnus John Gilmore (cygnus at yuba)
3892 Cleanup for gdb-3.94 release final:
3894 * Makefile.dist: Remove remote-vx.c, remote-nindy.c, and all
3895 the .c files from vx-share and nindy-share, from the various
3896 macros, since they are not found via ALLDEPFILES.
3897 (SFILES): Add tm-i960.h.
3898 (alldeps.mak rule): Break out ALLDEPFILES_MAINDIR and
3899 ALLDEPFILES_SUBDIR. List all the nindy and vxworks subdir files
3901 (TAGFILES_MAINDIR): Change ALLDEPFILES to ALLDEPFILES_MAINDIR.
3902 (gdb.tar.Z): Use ALLDEPFILES_SUBDIR as well as SFILES_SUBDIR.
3904 Mon Feb 25 16:02:35 1991 Cygnus John Gilmore (cygnus at oldman)
3906 * am29k-tdep.c: Add contribution line.
3907 (examine_prologue): Cache information about function prologues in
3908 the misc-function-vector to avoid lots of references over the
3909 serial line while examining instructions.
3911 * core.c (core_close): New function made from cleanup_core.
3913 * core.c, exec.c, inftarg.c, remote-eb.c, remote-nindy.c,
3914 remote-vx.c, remote.c, target.c, target.h,
3915 Update target_ops vector to add attach, close, and load entries.
3916 Use add_syms_addr_command, not add_file_addr_command, for
3917 add_file. Break out close routine from existing code.
3919 * dbxread.c (really_free_pendings): Don't free pending_blocks;
3920 they are in an obstack.
3921 (read_dbx_symtab): Relocate end_of_text_addr in the psymtab.
3923 (define_symbol): Add symbol type parameter; change callers;
3924 pass type parameter to DBX_PARM_SYMBOL_CLASS macro to allow
3925 it to influence the symbol class on the i960.
3926 (define_symbol): Swap LOC_CONST's into target byte order.
3928 * exec.c (exec_close): New function.
3929 (exec_file_command): Call it.
3931 * findvar.c (read_relative_register_raw_bytes): Doc byte order,
3932 Fix byte order of frame pointer.
3933 (read_var_value): Result of 0 if var's value can't be found,
3934 e.g. missing FRAME_ARGS_ADDRESS. Byte-swap LOC_CONST and
3935 LOC_LABEL values to target order. Add LOC_LOCAL_ARG.
3936 (locate_var_value): Use read_var_value and use its lazy address
3937 as the location of the var's value. Lint.
3939 * i960-pinsn.c (next_insn): Add routine from vxgdb for scanning
3942 * i960-tdep.c (arg_address, i960_frame_find_saved_regs): Remove
3943 obsolete Intel versions in favor of vxgdb versions.
3944 (check_host, byteswap, byteswap_val, reorder_val): Eliminate
3945 code dealing with byte order of values, which Intel did in host byte
3946 order rather than gdb-4's target byte order.
3947 (i960_frame_chain_valid): Move to nindy-tdep.c.
3948 (examine_prologue, skip_prologue, frame_find_saved_regs,
3949 frame_args_address, leafproc_return, saved_pc_after_call,
3950 pop_frame): Add vxgdb versions from Mark Fox.
3951 (examine_prologue, frame_struct_result_address): Add code
3952 to deal with the saved value of G13 (struct return address
3954 (frame_args_address): Modify Mark's version to prefer the
3955 saved value over the current value in the topmost frame.
3956 Cache result in the frame info to avoid performance hair in
3958 (print_fault): Add gdb960 code for printing faults.
3959 (_initialize_i960): Actually call check_host.
3961 * ieee-float.c (ieee_extended_to_double, ieee_double_to_extended):
3962 add stub routines. FIXME, these currently just return zero!
3964 * infcmd.c (program_info): Use PRINT_RANDOM_SIGNAL.
3965 (attach_command): Call target_attach, not target_open, now.
3967 * infrun.c (normal_stop): Make global, not static, for vx_attach.
3968 (child_attach): Rename from child_open.
3969 (wait_for_inferior): Use PRINT_RANDOM_SIGNAL. If stop_pc is zero,
3970 don't confuse it with a zero step_resume_break_address.
3972 * inftarg.c (child_detach): Eliminate inferior_pid test.
3973 (child_files_info): Clean up message a bit.
3974 (child_ops): Use child_attach, not child_open, to attach.
3976 * mem-break.c: #ifdef out the whole file if BREAKPOINT is not
3977 set (e.g. on VxWorks or NINDY). Move read_memory_nobpt from
3978 findvar.c to here, since it depends on the contents of the
3979 shadow_contents of breakpoints, but keep if #if 0 since it is
3982 * nindy-tdep.c: New file, contains nindy_frame_chain_valid, moved
3985 * printcmd.c (address_info): Handle LOC_LOCAL_ARG. Lint.
3986 (ptype_command, display_command): Eliminate have_inferior_p and
3987 have_core_file_p in favor of target_has_stack or
3988 target_has_execution.
3989 (print_frame_args): Handle LOC_LOCAL_ARG. Eliminate duplicate
3990 code for actually finding the values of arguments, though we still
3991 keep track of the maximum stack offset for use in printing unnamed
3992 arguments. Handle missing FRAME_ARGS_ADDRESS.
3994 * remote-nindy.c (i960_print_fault): Move to i960-tdep.c.
3995 (struct nindy_regs): Define registers passed to/from nindy.
3996 (nindy_fetch_registers, nindy_store-registers): Translate between
3997 nindy and GDB formats for the registers.
3998 (dcache_init): Statically allocate the cache, since it was being
3999 allocated by a malloc that was never freed anyway.
4000 (nindy_create_inferior): Error, not core dump, if no exec file.
4001 (nindy_before_main_loop): Use target_load, not target_add_file.
4003 * remote-vx.c (net_load): Specify large timeout for load
4004 requests. Allow user to break out with INTERRUPT.
4005 (net_break): Remove useless code, clean up. Change callers.
4006 (parse-args, skip_white_space, find_white_space): Clean up arg
4007 parsing to cope with quoted strings.
4008 (net_wait, net_quit): Never call error, just return status.
4009 (vx_read_register, vx_write_register): Cleanup status checking.
4010 #ifdef the code based on which CPU we are using (960 or 68k),
4011 FIXME, this should be completely general but it isn't yet.
4012 (vx_xfer_memory, vx_resume): Cleanup status checking.
4013 (vx_run_files_info): Improve message.
4014 (vx_load_command): Renamed from vx_add_file_command. Allow load
4016 (net_ptrace): Remove unused routine.
4017 (vx_wait): Adopt code from vxgdb960 to cope with broken
4018 connections to target machine and prompt to disconnect. Remove
4019 debug printouts. Map some EVENT_'s to SIGnals.
4020 (add_symbol_stub, vx_open): Print names of object files we found,
4021 and "ok" if we read their symbols OK. Clarify output in general.
4022 (vx_attach, vx_detach, vx_kill): Add these commands.
4023 (vx_convert_from_virtual, vx_convert_to_virtual): Simplify.
4024 (vx_run_ops): Turn off all_mem, to avoid spurious msg in the
4025 "info files" output, and create_inferior, since we already have
4028 * stack.c (frame_info): Replace Frame_unknown with 0.
4029 (print_frame_arg_vars): Handle LOC_LOCAL_ARG.
4030 (return_command): Pop until the PC matches as well as the FP,
4031 so it works even if the FP is shared with another function,
4032 as in "frameless" or "leaf" procedures.
4034 * symfile.c (load_command): renamed from add_file_target_command.
4035 (add_syms_addr_command): renamed from add_file_addr_command.
4036 (add_syms_command): Stub to call target_add_syms.
4037 (_initialize_symfile): Change command names and descriptions,
4038 add-file => add-syms, and load from alias to its own command.
4040 * target.c (kill_or_be_killed, maybe_kill_then_attach,
4041 maybe_kill_then_create_inferior): Default for attempts to start
4042 a process, if one is already running, is to ask about killing
4043 it and retry if yes.
4044 (upstack_create_inferior): #if-0 it, strata obsolete it.
4045 (push_target, unpush_target, pop_target): to_close() a target
4046 before unstacking it.
4047 (target_info): Renamed from target_files_info.
4048 (_initialize_targets): Rename "i files" as "i target", accessible
4051 * target.h: Improve comments about the target_ vectored routines.
4053 * tm-i960.h: Remove NINDY-specific stuff to tm-nindy960.h.
4054 Convert commenting style to standard GNU style.
4055 (DBX_PARM_SYMBOL_CLASS): allow LOC_LOCAL_ARG's to be recognized.
4056 (SKIP_PROLOGUE): No longer a no-op.
4057 (SAVED_PC_AFTER_CALL): Now handles leaf procedures.
4058 (*_REGNUM): Sort register numbers.
4059 (REGISTER_BYTES, REGISTER_BYTE, REGISTER_RAW_SIZE,
4060 MAX_REGISTER_RAW_SIZE, REGISTER_CONVERTIBLE,
4061 REGISTER_CONVERT_TO_VIRTUAL, REGISTER_CONVERT_TO_RAW): Float regs
4062 are now 10 byte extendeds, not 8 byte doubles.
4063 (FRAME_CHAIN_VALID): Make this config-dependent, since it differs
4064 for nindy versus vxworks targets. FIXME, this should possibly go
4065 in the target vector.
4066 (EXTRA_FRAME_INFO, INIT_EXTRA_FRAME_INFO): Cache both
4067 frame_saved_regs and arg pointer with each frame.
4068 (FRAMELESS_FUNCTION_INVOCATION): New leafproc support.
4069 (FRAME_ARGS_ADDRESS): Use cached result.
4070 (FRAME_ARGS_ADDRESS_CORRECT): New, avoids g14 guessing.
4071 (FRAME_FIND_SAVED_REGS): Change arg to subsidiary fn.
4072 (PRINT_RAMDON_SIGNAL): Call print_fault.
4073 (POP_FRAME): Now works.
4075 * tm-nindy960.h: Break this off tm-i960.h. NINDY-specific
4076 option parsing and startup; STACK_END_ADDR, FRAME_CHAIN_VALID,
4077 BREAKPOINT, and DECR_PC_AFTER_BREAK are here.
4078 (ADDITIONAL_OPTION_HANDLER): use target_load, not
4081 * tm-vxworks960.h: Break this off tm-i960.h. VxGDB specific
4082 startup; DECR_PC_AFTER_BREAK, and FRAME_CHAIN_VALID are here.
4084 * valarith.c (value_subscripted_rvalue): Avoid handling
4085 floats and doubles specially; it gave alignment errors. Lint.
4087 * valops.c (value_of_variable, value_of_this): Error if unknown
4090 * valprint.c (print_floating): Bcopy rather than pointer-deref,
4091 to avoid alignment problems.
4092 (value_print): Handle unknown value address.
4093 (cplus_val_print): Two args are ignored; remove them. Change caller.
4094 (val_print): Use unpack_long rather than pointer-deref.
4097 (unpack_long, unpack_double): Use bcopy rather than pointer-deref
4098 to avoid alignment problems.
4099 (value_being_returned): Error if return value unknown.
4100 (set_return_value): Add bogosity warning, FIXME. *
4102 * TODO: A woman's work is never done.
4104 * Makefile.dist: Distribute REMOTE_OBS into tconfig files.
4105 Separate INCLUDE_CFLAGS for use with lint. Add LINTFILES.
4106 Add ieee-float.o to OBS.
4107 * tconfig/{nindy960,vxworks68,vxworks960}: Include the desired
4108 REMOTE_OBS remote-interface files in the TDEPFILES and TM_FILE.
4109 * tconfig/i960: FIXME. Half-merge, produce warning if config'd.
4111 Changes to generalize the VxWorks RPC protocol slightly, to handle
4112 i960 as well as 68000.
4114 * vx-share/dbgRpcLib.h (VX_SOURCE_STEP): Add.
4115 * vx-share/reg.h: Produce i960 regs #ifdef I80960
4116 * vx-share/xdr_ptrace.c: Skip FPA registers if 960.
4117 * vx-share/xdr_rdb.h: Add SOURCE_STEP struct and xdr decl.
4118 * vx-share/xdr_rdb.c: Add xdr_SOURCE_STEP routine.
4119 * vx-share/xdr_regs.c: Add xdr_regs, xdr_fp_status, xdr_ext_fp
4120 for i960. Change xdr_vectors to xdr_opaques for 68k registers,
4121 so they will move in target byte order rather than network
4122 byte order (happens to be the same).
4124 Mon Feb 25 03:41:44 1991 John Gilmore (gnu at cygint.cygnus.com)
4126 * tm-convex.h (END_OF_TEXT_DEFAULT): Remove #if 0'd block.
4128 Sun Feb 24 00:55:53 1991 John Gilmore (gnu at cygint.cygnus.com)
4131 Add contribution lines to various files, showing where they
4134 * breakpoint.c (break_insn, check_break_insn_size,
4135 read_memory_nobpt): Remove to mem-break.c.
4137 * xm-*.h, param-no-tm.h, tm-29k.h, valprint.c: Change BYTE_ORDER to
4140 * tm-29k.h (STAB_REG_TO_REGNUM): Warn user if symbol table
4141 entry has bad register number. This change is not
4142 tested in this release, FIXME.
4144 * frame.h: Eliminate Frame_unknown in favor of a simple zero.
4147 * value.h: Force value's contents field to be aligned to hold
4148 at least a double or a long long (if supported). This avoids
4149 doing bcopy's in and out of the contents field.
4151 (step_1): Avoid coredump under obscure circumstances when we
4154 * symtab.h (misc_info): Add field to misc function vector for
4155 any kind of cached information the target code desires. AMD
4156 29000 uses this to avoid repeating examine_function_prologue's.
4158 * coffread.c: Lint. Remove static symfile, read_section_header.
4159 core.c (have_core_file_p): Lint: remove.
4160 expprint.c (print_subexp): Lint.
4161 infptrace.c, valops.c, valprint.c: lint.
4163 Roll in changes from vxgdb-5.0.1:
4165 * symtab.h: Comment byte order of each address class. Add
4166 LOC_LOCAL_ARG for frame-relative args (960).
4167 expread.y: Use LOC_LOCAL_ARG where LOC_ARG is used.
4168 symtab.c, symmisc.c: ditto.
4170 * infrun.c (init_wait_for_inferior): Clear stop_signal.
4172 * remote.c (remote_resume): Error if resume with a signal.
4174 * symfile.c (prim_record_misc_function): Clear misc_info.
4175 (fill_in_vptr_fieldno): Check stub type of arg.
4177 * valops.c (value_cast): Avoid looking up names of types whose
4178 name we don't know, to prevent coredump. Sun CC produces typedef
4179 rtx and the name of *rtx is zero...
4181 Mon Feb 18 21:16:25 1991 John Gilmore (gnu at cygint.cygnus.com)
4183 Roll in changes from final AMD 29000 port (Tiemann).
4185 tconfig/am29k: Add COFF_ENCAPSULATE and TARGET=TARGET_AM29K
4186 for ../include/a.out.encap.h. This might not work now that BFD
4187 is separately compiled. Instead, BFD support for encap will have
4188 to translate machine type 29k into the right COFF_MAGIC.
4190 * infcmd.c: Remove references to inferior_pid that aren't used
4191 in actual ptrace calls; use target_has_execution, etc.
4192 (have_inferior_p): Remove function.
4193 (program_info): Print target info rather than "process number";
4194 avoid gratuitous messages unless from_tty.
4195 (run_stack_dummy, finish_command): Set proceed_to_finish.
4196 infrun.c: Remove inferior_pid refs. Decl & init proceed_to_finish.
4197 main.c: Lint. Lose have_inferior_p().
4198 inferior.h (have_inferior_p): Remove, lint.
4199 (proceed_to_finish): Add flag to ask that all regs be saved
4200 by normal_stop, for the few commands that need it, speeding up
4201 serial I/O. Add comments to stop_registers.
4203 * remote-eb.c: Remove newline from breakpoint message we grep
4204 for. Never time out when running the user program.
4208 Wed Feb 13 15:34:40 1991 John Gilmore (gnu at cygint.cygnus.com)
4210 Roll in changes from vxgdb-5.0.1:
4212 * dbxread.c (read_dbx_symtab): If we encounter a "FORTRAN COMMON"
4213 symbol in its raw form, we are processing an unlinked ".o" file.
4214 See if the target environment has assigned it an address, using
4215 target_lookup_symbol (VxWorks does), and enter it into the symtab
4218 * tm-vxworks.h (FRAME_CHAIN, FRAME_CHAIN_VALID): Override usual
4219 68k versions for a simpler version that assumes zero FP at bottom.
4220 Fixes bug of truncated stack reports.
4222 * target.h (target_lookup_symbol): Define this routine's args
4223 and result, finally.
4225 * target.c (nosymbol): Default routine for target_lookup_symbol.
4226 (target_default): Default lookup_symbol and call_function too.
4227 (files_info): Only print has_all_memory warning if a non-dummy
4230 * remote-vx.c (vx_read_register, vx_convert_to_virtual,
4231 vx_convert_from_virtual): If target does not have floating point,
4232 zero register "values", and avoid doing cross-net conversions.
4233 (vx_lookup_symbol): Rename net_lookup_symbol, add to vectors.
4234 (vx_open): Rearrange code that attaches to target and reads
4235 symbols for all loaded modules, to work if some of the modules
4236 are not accessible. Add symbol_stub() and add_symbol_stub()
4237 as callbacks from catch_errors(). Allow connect attempt to be
4238 interrupted painlessly with ^C (FIXME, there are still some bugs
4239 if the interrupt happens during symbol reading.). Print
4240 final message with puts_filtered, since symbol messages are
4245 * main.c (catch_errors): Only print errstring if non-null.
4246 (command_loop): Avoid an ioctl per command to test ISATTY.
4248 * remote-vx.c (net_load): make static; avoid sophomoric msg.
4249 (vx_xfer_memory): Return correct result!
4250 (vx_files_info): Indicate whether target has float or not.
4251 (vx_lookup_symbol): Complain, not error, if target gone.
4252 (vx_open): Print "Connected" msg before disabling immediate-quit.
4253 [FIXME: lookup_symbol and vx_open changes need testing.]
4255 target.c, remote-eb.c, inftarg.c, am29k-opcode.h, target.h,
4256 tm-29k.h, tmm-vxworks68.h, symfile.c, gdb-int.texinfo: Add
4257 contributor lines and update copyrights to 1991.
4259 Changes from an attempted H-PUX host port:
4261 * infptrace.c (PT_ATTACH, PT_DETACH): Handle HP/UX, which
4262 defines PT_ATTACH and PT_DETACH but not PT_KILL.
4263 * remote-eb.c (eb_open): Misplaced endif kills sysv H/PUX.
4264 * remote-vx.c: include <sys/time.h> for HPUX.
4265 * hp300hpux-xdep.c (fetch_core_registers): Rewrite old
4266 "core_file_command" routine to BFD regime. May not work yet.
4268 Attempted port of "gdb-3.4 Van Jacobson xgdb" to modern gdb.
4270 * xgdb.c: Replace X10 version with some VJ version.
4271 (FIXME: Its copyright assignment is not on record.)
4272 * xgdb.c: Update include files to X11R4 (Xaw crud).
4273 (xgdb_display_source, create_text_widget): fix call to
4274 get_filename_and_charpos. Rewack source window stuff for X11R4
4275 (gleaned from include files, and "nm's" of binary libraries, since
4276 I had no doc available).
4277 (append_selection, append_selection_word): Disable with FIXME
4278 since R4 changed interface here.
4279 (create_buttons): Add back the old set of buttons.
4280 (xgdb_create_window): Fix call to XtInitialize (&argc not argc).
4282 * Makefile.dist (xgdb, xgdb-init.c): Update for X11R4 on Suns.
4283 Roll VERSION to 3.94 (not yet final though).
4285 Sat Feb 9 09:46:25 1991 John Gilmore (gnu at cygint.cygnus.com)
4287 * obstack.h (obstack_ptr_grow, obstack_ptr_grow_fast,
4288 obstack_int_grow, obstack_int_grow_fast): Eliminate
4289 cast on left of assignment, which gives MIPS cc fits and is
4292 * sparc-pinsn.c (print_insn): Eliminate 'set' test, subsumed by
4293 F_ALIAS. Use printf, not fprintf, when not passing a file
4295 (compare_opcodes): Check that identical instructions have
4296 identical opcodes, complain otherwise.
4298 * sparc-opcode.h (st %fsr): Fix opcode "lose" mask. This
4299 was reported by Roland McGrath.
4300 (unimp): Only match if exactly zero instruction. (Roland)
4301 (branches and traps): Generate all variations of these
4302 instructions with macros, based on a single call that defines
4303 each condition name and its binary representation.
4304 (set): Turn on alias bit, to avoid test in sparc-pinsn.c.
4306 * valprint.c (val_print_fields): Take, and use, format parameter.
4307 This means that "p/x struct" again prints the elements in the
4308 desired format. Changed callers.
4310 * stack.c (frame_info): Use filtered output, and indicate wrap
4311 points. Remove kludgy formatting designed to avoid line wrap.
4313 * utils.c (wrap_here): If the line is already full (because
4314 we had printed a long indent or long wrapped string), do an
4315 immediate newline-and-indent.
4317 * m68k-pinsn.c (print_insn_arg): Bugfix from
4318 ntmtv!thompson@ames.arc.nasa.gov (Mike Thompson): 'bkpt #0'
4319 instruction is incorrectly disassembled as bkpt #8.
4321 * dbxread.c (end_psymtab): Bugfix from Peter Schauer
4322 <pesrem@regent.e-technik.tu-muenchen.de>: If you want to set a
4323 breakpoint in a *.y file gdb will say Reading in symbols for *.y...
4324 and then will dump core (sometimes). I traced it back to an
4325 uninitialized symfile_name in psymtab_to_symtab.
4326 (const_vol_complaint): Add quotes to message.
4327 (define_symbol): Only believe line number if gcc_compiled.
4328 Avoid allocating symbol if we will not return it.
4330 Add target strata support so that newly established targets go
4331 into their right place in the target stack (e.g. a new exec file
4332 doesn't wipe out the ability to access the running process).
4334 * target.h, core.c, exec.c, inftarg.c, remote-eb.c,
4335 remote-nindy.c, remote-vx.c, remote.c, target.c: Add to_stratum
4336 and initialize it properly in all the targets.
4338 * target.h: Document strata. Change return type of push_target.
4340 * target.c (nomemory): new function for dummy memory access.
4341 (tcomplain): Rename complain, now also used in symfile.c.
4342 (push_target): Push targets within strata. New return value shows
4343 whether new target is on top of stack or not. Always keep dummy
4345 (target_files_info): Ignore dummy target.
4347 * core.c (core_open): Warn user, and skip accessing file, if the
4348 core target is not the topmost target in the stack.
4349 * remote-nindy.c (nindy_create_inferior): Avoid unpush_target, now
4352 * remote-vx.c: Remove vx_prepare_to_store from vxworks memory
4353 target_ops, it doesn't belong there since we have no regs there.
4354 Change name of target from machine => memory to clarify.
4356 Thu Feb 7 16:32:09 1991 John Gilmore (gnu at spiff.cygnus.com)
4358 * Freeze version 3.93 for release.
4360 * Makefile.dist: Handle vx-share and nindy-share subdirs
4361 properly when building gdb.tar.Z.
4363 * symtab.c: lint; add no_symtab_msg to consolidate the messages
4364 printed in various places, so I could change just one copy.
4366 * dbxread.c, coffread.c: Change references to bfd->iostream
4367 to cast to FILE *, now that BFD avoids needing types defined
4368 in other header files.
4370 Tue Feb 5 21:39:35 1991 John Gilmore (gnu at cygint.cygnus.com)
4372 * command.c, dbxread.c, expprint.c, infcmd.c, infptrace.c,
4373 infrun.c, printcmd.c, remote-nindy.c, source.c, sparc-tdep.c,
4374 sparc-xdep.c, symfile.h, symmisc.c, utils.c, valprint.c: Lint
4375 (actually gcc -Wall).
4377 * dbxread.c: Remove first_global_sym, last_global_sym, since
4378 they are never referenced.
4380 * defs.h (baud_rate): Declare.
4381 main.c: Define it, and add the -b option to set it.
4383 * gdb-int.texinfo: Add text on how to define a new host or target
4384 architecture, prompted by Per Bothner's questions about MIPS
4387 * gdb.texinfo: Document "complaints". Change doc of -q since
4388 gdb no longer prints the copyright and blurb if you specify a file
4389 name to be debugged (just like Emacs). Add doc for Nindy-specific
4390 command line flags for specifying target serial port and such.
4391 Update copyright to 1991.
4393 * gdbcore.h: Remove a large mass of now-useless crud, since BFD
4394 has taken over for us the job of ripping up executable files. The
4395 crud caused Per Bothner's port to not compile.
4397 * infrun.c (normal_stop): Avoid printing "Program exited
4398 normally" if we are in batch mode. This allows a GDB which
4399 executes a program on a target system, to behave like a Unix
4400 command (input from stdin, output to stdout, no extraneous
4403 * main.c (main): Allow additional machine-dependent command line
4404 options to be specified with the ADDITIONAL_OPTIONS,
4405 ADDITIONAL_OPTION_CASES, ADDITIONAL_OPTION_HELP, and
4406 ADDITIONAL_OPTION_HANDLER macros. Also allow machine-dependent
4407 processing to occur just before the main loop with
4408 BEFORE_MAIN_LOOP_HOOK.
4409 (main): If a "core file" argument is specified, and it is not a
4410 core file, try it as a process ID to attach.
4411 (symbol_completion_function): Attempt to cope with
4412 "show screen-" TAB, not very successfully. This needs more work,
4414 (batch_file): New function, returns whether we are reading
4415 commands from an interactive tty on stdin, or from somewhere else.
4416 Called by normal_stop since it doesn't get from_tty passed down
4417 to it like many commands do.
4419 * remote-nindy.c: Handle command line options for nindy
4421 (nindy_before_main_loop): Prompt user for tty name if they
4422 don't specify it before getting to the interactive command loop.
4424 * tm-i960.c: Add ADDITIONAL_OPTIONS, etc, to handle -O, -brk,
4425 and -r command line options. Also add hook before main loop
4426 to make it easy to specify a tty.
4428 * TODO: More things to do, one done.
4430 Mon Feb 4 23:57:39 1991 John Gilmore and Mike Tiemann (at cygint.cygnus.com)
4432 * dbxread.c: Make complaint() calls pass pointer, not struct.
4433 Add complaints about badly formatted C++ type information
4434 (const/volatile indicator, and parse errors resulting in
4435 error_type). Fix C++ virtual member fn comment.
4436 (read_struct_type): Avoid bumping pointer if we got a parse
4437 error; this prevents our walking beyond the end of a string.
4438 Terminate loop on null char as well as semicolon.
4439 (process_one_symbol): Fix the LBRAC fix so that it uses the
4440 last previous SLINE, FUN, or SO record's PC address. C++ debug
4441 symbols did not have SLINE records in a useful order compared
4442 to the LBRAC records.
4443 (define_symbol): Handle "catch" records.
4445 * symtab.c (check_stub_type): Added new complain
4446 `stub_noname_complain' and added a consistency check to
4447 keep the debugger from crashing when finishing from an
4448 exception frame. A real fix will be needed later.
4450 Sat Feb 2 10:43:05 1991 John Gilmore (gnu at cygint.cygnus.com)
4452 * infcmd.c (attach_command): Make global.
4454 * Makefile.dist (REMOTE_OBS): Make these compile by default,
4455 but make them easy to comment out. Perhaps later they should
4456 be enabled by what CPU you configure for? FIXME.
4457 (VERSION): Roll to 3.93.
4458 (pinsn.o): Remove rule for obsolete file.
4459 (dbxread.o,coffread.o,mipsread.o): Use ${srcdir} explicitly.
4461 Run down a problem that manifested by printing the wrong function
4462 name in stack traces of read_ofile_symtab. Turned out that the
4463 problem was the SunOS 4.1.1 (and previous) C compiler outputs
4464 the LBRAC symbol with an address in the *data* segment, which
4465 blew our binary search through the blocks.
4467 * dbxread.c: Use the complain() facility consistently to bitch
4468 about problems in the symbol file we are reading.
4469 (finish_block): Add code to check the nesting of the blocks;
4470 complain and Procrust them to fit if wrong.
4471 (make_blockvector): Check the order of the blocks, complain
4472 [but don't cope] if wrong.
4473 (process_one_symbol): ifndef SUN_FIXED_LBRAC_BUG, check LBRAC
4474 symbols to be sure their PC value is greater than the last SLINE
4475 (line number) symbol we've seen, complaining and adopting the
4476 SLINE PC value if wrong.
4478 * symfile.h (struct complaint, complaint_root, complain,
4479 clear_complaints): Add.
4480 * symfile.c (complain, complaint_root, clear_complaints): Add
4481 facility to deal with non-fatal complaints and to regularize their
4483 (symbol_file_add): Clear complaint counters to allow new complaints.
4484 (initialize_symfile): Add 'set complaints' and 'show complaints'.
4486 * dbxread.c (dbx_symfile_read): Remember the address and size
4487 of the string table for the main symbol file, so we won't read it
4489 (dbx_psymtab_to_symtab): Fix the check for main symbol file,
4490 to avoid reading the string table yet again. Lint.
4491 (throughout): Improve filtered output, including word wrap.
4492 (read_range_type): Improve Bothner's fix to handle other types too.
4494 * utils.c: Improve line wrap implementation. Handle unlimited
4495 width by making chars_per_line unsigned.
4496 (puts_filtered): New, easy, function.
4498 * defs.h (puts_filtered): add.
4500 * mipsread.c (compare_symbols, sort_symtab): Remove these fns,
4501 call the identical sort_symtab_syms() in symfile.c instead.
4503 * expread.y: Suggest the `file' command rather than `symbol-file'.
4505 * command.h (enum var_types): Add zinteger for seroable
4507 * command.c (do_setshow_command): Handle var_zinteger. Restructure
4508 nested if's into a switch.
4510 * breakpoint.c (bpstat_print): If bpstat "print" flag is not set,
4511 we did not stop because of a breakpoint (it must have been for
4512 some other reason, like a "stepi"), so don't print anything.
4514 * symtab.c: Include <sys/types.h> all the time. Now that BFD
4515 doesn't include <sys/types.h>, old SunOS's require it for
4518 Sat Feb 2 10:39:15 1991 Per Bothner (bothner@cs.wisc.edu)
4520 A test port of gdb-3.92.6 to the Sony NEWS.
4523 Don't normally link in remote- or vx stuff.
4524 Some of it doesn't compile, and it wastes space for 99% of the users.
4525 Remove reference to no-longer-used HAVE_VPRINTF.
4526 Fixed BFD_DEP typo to BFD_DIR.
4528 Fix cast in arg to bfd_h_getlong.
4529 Make char *prefix be const.
4530 Fix how certain range types are mapped into builtin unsigned int types.
4532 Remove 2 #includes. They cause errors (on Sony, at least),
4533 and aren't needed (they wern't in earlier versions).
4535 print_address_symbolic should never demangle labels
4536 (since it prints *assembler-level* labels).
4538 [This was superseded by the change to printcmd below.]
4541 Add some "volatile" return types to avoid warnings.
4542 If MISSING_VPRINTF add vprintf function and not just macro
4543 (since vprintf is used in printcmd.c).
4545 Unless __GNUC__, use obstack_grow instead of obstack_ptr_grow.
4546 (The latter isn't grokked by some PCC-based compilers.)
4548 [This change is in abeyance, we prefer to fix obstack_ptr_grow.]
4550 Make chunk size of dont_print_obstack 32*4 instead of default 4096.
4551 * nindy-share/coffstrip.c
4552 Added some forward declarations (otherwise, gcc complains
4553 about implicit extern redefined as static).
4555 Sun Jan 20 02:38:19 1991 John Gilmore (gnu at cygint.cygnus.com)
4557 Changes inspired by Per Bothner:
4558 * printcmd.c (print_address_symbolic): Take additional parameter
4559 specifying whether to demangle.
4560 (print_address): Pass in asm_demangle to control demangling.
4561 (print_address_demangle): New fn, takes explicit arg to control
4563 * utils.c: Add new vars demangle and asm_demangle, and let them
4565 (fputs_demangled): If !demangle, just print the argument.
4566 (fprint_symbol): If !demangle, just print raw symbol.
4567 * valprint.c (val_print): Call print_address_demangle rather than
4568 print_address, to cause demangling to depend on the global
4569 rather than assembler-level demangling setting.
4570 * WHATS.NEW, gdb.texinfo: Document.
4572 * main.c (show_command): Show all settings if no arg.
4573 (initialize_main): Make "info set" the same as naked "show".
4574 * command.c (cmd_show_list): Handle prefix commands in the
4575 list, and print the name of the setting as well as its English
4576 description and value.
4578 Allow gdb functions to specify where a line should wrap if it
4579 exceeds the size of a terminal line. Use it to make the output
4581 * utils.c (set_screen_width_command): New fn, mallocs a buffer
4582 of the right size when screen width changes.
4583 (set_screensize_command, screensize_info): Remove #if 0'd fns.
4584 (wrap_here): New fn, indicates a point in the output where we
4585 should wrap the line rather than just letting it overflow at a
4587 (fputs_filtered): Implement wrapping.
4588 (n_spaces): New fn, returns a pointer to N spaces.
4589 (print_spaces_filtered): Use n_spaces.
4590 * defs.h (n_spaces): Declare.
4591 * stack.c (print_frame_info): Wrap with 4-space indent after
4592 fn name and before filename and line number.
4593 * printcmd.c (print_frame_args): Wrap with 4-space indent
4594 before each argument name is printed.
4595 * valprint.c (value_print): Wrap with no indentation before
4597 (val_print_fields): Wrap with indentation relative to nesting
4598 level before each field name.
4599 (val_print): Wrap with nesting indentation before array elements.
4600 * command.c (do_setshow_command): Avoid extra newlines,
4601 wrap with 4-space indent around values printed, end with period.
4602 * WHATS.NEW, gdb.texinfo, gdb-int.texinfo: Document.
4604 * breakpoint.c (breakpoint_1): Implement addressprint for
4605 "info breakpoints" display. Change file name and line number
4606 format to " at file:nnn" rather than " (file line nnn)".
4607 * gdb.texinfo: Document.
4610 Fri Jan 18 07:21:25 1991 John Gilmore (gnu at cygint.cygnus.com)
4612 Frozen for gdb-3.92.6 release.
4614 README, WHATS.NEW: Update for 3.92.6 release.
4616 tconfig/{altos, i386v, i386v32, m88k, umax}: Eliminate
4617 coffread.o from configs since it is now built by default.
4618 tconfig/{3b1, altosgas, arm, convex, hp300bsd, hp300hpux,
4619 i386v-g, i386v32-g, isi, merlin, news, news1000, np1, pn,
4620 pyramid, symmetry, vax, vxworks68}: Eliminate dbxread.o
4621 from configs since it is now built by default.
4623 Makefile.dist: Update for release 3.92.6. Handle files that
4624 have been moved to ../include, ../getopt, or ../bfd. Add
4625 saber.suppress and tests directory. Add config.status to
4626 the release (it will say "none").
4628 coredep.c: Minor formatting fixes.
4630 These changes were made in early December but only checked in now:
4631 * nindy-share/Onindy.c, nindy-share/coffstrip.c,
4632 nindy-share/nindy.c: lint
4633 * nindy-share/nindy.c (ninStopWhy): Don't byteswap the
4634 register values coming back from the target; we store values
4635 in target byte order everywhere.
4637 Wed Jan 16 19:01:37 1991 John Gilmore (gnu at cygint.cygnus.com)
4639 * am29k-opcode.h, am29k-pinsn.c: Add 29050 opcodes.
4641 * valprint.c (cplus_val_print, val_print_fields): New functions,
4642 which print C++ objects. They conspire to avoid printing a
4643 virtual base class more than once, following all the twists and
4644 turns of C++ virtual base rules.
4645 (val_print): Call the above rather than do it by hand.
4647 * symfile.c (symbol_file_add): Only reset symfile_mtime for main
4648 symbol file, not for added files like shared libs. This really
4649 needs to be generalized to a timestamp per file.
4651 * core.c (cleanup_core): Avoid coredump if no core file.
4653 * config.gdb: Accept -host or -target in place of +host or
4656 * coffread.c (find_linenos): Avoid desupported BFD interface
4657 to line numbers. We still read them manually rather than using
4658 BFD's "generic" features.
4660 * gdbrc.tex, threecol.tex: Add GDB reference card and its
4662 Makefile.dist: Add refcard to OTHERS list for creating tar files.
4664 * Makefile.dist: Eliminate use of $< in explicit targets.
4666 * readline/Makefile: Use $< rather than $*.c, which does not
4667 include the VPATH in GNU Make.
4669 * tconfig/i960-bout, tconfig/i960-coff: These are identical
4670 copies of tconfig/i960, added for global configuration
4671 compatability. All i960 versions can read both coff and b.out.
4673 * tm-88k.h: Fix multiline macro that lacked \'s. Remove
4674 COFF_FORMAT and COFF_CHECK_X_ZEROES since these are now handled
4677 * TODO: Think of more things to do.
4679 Wed Jan 2 19:09:29 1991 John Gilmore (gnu at spiff.cygnus.com)
4681 tconfig/{am29k,i960,sun2*,sun3*,sun4*}: Eliminate config
4682 of sdb versus dbx debug symbols. Add kludge for 68881 80-bit to
4683 64-bit float conversion.
4685 tconfig/sun4, tconfig/sun3, xconfig/sun4, xconfig/sun3: Make
4686 equivalent to sun?os4 so global config works.
4688 Wed Jan 2 18:20:51 1991 John Gilmore (gnu at spiff.cygnus.com)
4690 Fix from Eberhard Mattes <mattes@azu.informatik.uni-stuttgart.de>
4692 * main.c: Only declare linesize once; declare pagesize not at
4693 all, since it is never used.
4694 (main): Clear newly allocated line before it is used.
4696 Fri Dec 28 00:13:42 1990 John Gilmore (gnu at cygint)
4698 Further stabilization for the Intel 960.
4700 * Makefile.dist: Parameterize the location of the "include"
4701 and "bfd" directories, as well as "getopt". Add symfile.c.
4702 Link in both dbxread and coffread. Fix up "make depend" to
4703 rewack the locations of include, bfd, and getopt in its output.
4705 * README: Document moving include files, improve some of
4708 * coffread.c: Move common code out to symfile.c. Change
4709 symbol_file_command style interface to use new *_symfile_init
4710 and *_symfile_read interface under BFD. Use BFD internal
4711 info to locate line table, symbols, etc.
4713 * core.c (core_fetch_registers): Rename to get_core_registers
4714 to avoid confusion with fetch_core_registers.
4715 (register_addr): Move to coredep.c, which is already machine
4716 dependent. This leaves core.c pretty clean of dependencies.
4718 * coredep.c (register_addr): Accept this routine from core.c.
4720 * dbxread.c: Move common code (with coffread.c, etc) into new
4721 symfile.c. Each psymtab now contains a pointer to the
4722 format-dependent function that knows how to read it in. Make
4724 (dbx_psymtab_to_symtab): Renamed from psymtab_to_symtab_2.
4725 (process_one_symbol): Add code to complain about a "compiler bug
4726 we muzzle here", if we actually see it.
4728 * eval.c (evaluate_subexp): Insert missing "break" statements
4729 in code that determines whether a variable is an lvalue in
4730 memory, register, or whatever. I detected this via a compiler
4731 bug in which it *almost* mashed out the whole switch statement.
4733 * gdb-int.texinfo: Add minor sections on configuring gdb for
4734 release, and about the README file.
4736 * infcmd.c (registers_info): Fix formatting somewhat. Still
4737 not as pretty as before, but it handles byte swapping.
4739 * remote-nindy.c: If data cache routines are interrupted while
4740 waiting for the remote end, be sure that any uninitialized cache
4741 blocks are on the free list, not on the valid list!
4743 * symfile.h: Flesh out this header file with all the various
4744 routines and variables that have been merged in from dbxread.c
4745 coffread.c, and symtab.c to symfile.c.
4747 * symfile.c: New file, containing code common to dbxread.c,
4748 coffread.c, and some code from symtab.c. All generic code for
4749 reading symbol files should be in here now.
4750 (unrecord_misc_function): Remove unused function.
4752 * symtab.h: Remove file-reading things to symfile.h.
4754 * symtab.c: Remove file-reading things to symfile.c.
4756 * tm-i960.h: Fix FRAME_CHAIN types; define PRINT_RANDOM_SIGNAL
4757 to decode i960 fault types.
4759 * target.h, remote.c, remote-eb.c, remote-vx.c, remote-nindy.c,
4760 target.c: Change type of the "resume" function from int to void,
4761 since its result was never used.
4763 Sat Dec 22 02:51:40 1990 John Gilmore (gnu at cygint)
4765 * main.c: Replace "stupid" with "caution"; you now "set caution
4768 * printcmd.c (print_scalar_formatted): Fix typo in 'g' format
4770 * infcmd.c (do_registers_info): Call val_print to deal with the
4771 byte order of the registers being printed. FIXME, this makes
4772 the formatting of the output uglier.
4774 * infcmd.c (wait_for_inferior): If PRINT_RANDOM_SIGNAL is
4775 defined, call it for signals the debugger doesn't itself use.
4776 The i960 uses this for more detailed fault information.
4778 * remote.c (remote_open): If arg is null, print help rather than
4781 * sparc-xdep.c (register_valid): Avoid declaring size, since
4782 various modules will think of various sizes depending on the
4783 architecture of their tm-file. FIXME, we need protection against
4784 actually entering one of those modules, which would clobber
4785 storage if not for the target architecture compiled into gdb.
4787 * stack.c (up_command, down_command): Always print the frame
4789 (up_silently_command, down_silently_command): New commands
4792 * i960-pinsn.c (reg), i960-tdep.c: Lint.
4794 * i960-tdep.c (i960_frame_chain_valid): Lookup_symbol now takes
4795 more parameters than it used to.
4797 * findvar.c (registers): Increase slop to 256 bytes, which should
4798 protect us against even most RISC machines with large register
4800 (locate_var_value): Move declaration inside related ifdef.
4802 * remote-nindy.c (): Use TIOCSETN rather than TIOCSETP
4803 throughout, to avoid throwing away buffered input from the board.
4804 (nindy_wait): Supply_register takes addr_of_value, not value.
4805 (i960_print_fault): Renamed from i80960_fault.
4806 (nindy_fetch_registers): Avoid have_regs stuff, just get them.
4807 (nindy_store_registers): Avoid regs_changed stuff, just stuff
4809 (nindy_create_inferior): Don't bother to write PC_REGNUM since
4810 we can set the PC in the call to proceed(). Unpush nindy_ops
4811 before pushing it on top, to avoid message to user. Eliminate
4812 commentary from Unix machines that just misleads here.
4813 (reset_command): Fix error message to suggest target command.
4815 Wed Dec 19 11:03:56 1990 John Gilmore (gnu at cygint)
4817 Release 3.92.5 as frozen.
4819 Stabilize the merged release...with help from lint, Saber C,
4822 Everywhere: Add include files needed to declare return types
4823 of functions called.
4825 * gdb.texinfo: Roland Pesch is documenting gdb, glory be!
4827 * breakpoint.h: Add undeclared breakpoint functions, and some
4828 functions for display handling since I couldn't think of a better
4831 * breakpoint.c (insert_breakpoints): Make code for disabling
4832 shared library bkpts more likely to work. It's used when we
4833 rerun a program and stop before the shared library has been
4835 (breakpoint_cond_eval, bpstat_stop_status): Pass arg as int,
4836 cast from pointer, so it squeezes through catch_errors.
4837 (bpstat_stop_status): Fix logic broken some time ago. We now
4838 always create a bpstat if the stop address matches a breakpoint,
4839 even if we don't stop there -- just like the old code used to do
4840 before I got my fingers into it (sigh).
4841 (breakpoint_1): Print "ignore count" after "stop only if"
4842 condition, since that's how it actually works.
4843 (mention): Handle watchpoints as well as breakpoints.
4844 (watch_command): use set_raw_breakpoint and mention to do most
4845 of the work (and initialize all the fields!). Only pass one
4846 arg to parse_c_expression, since that's all it takes.
4848 * command.c (not_just_help_class_command): Rename arg to args
4849 since we ignore "unused argument" warnings on vars named "args".
4850 inflow.c (child_terminal_info): ditto.
4851 infptrace.c (kill_inferior): ditto
4852 main.c (catch_errors, version_info, quit_command, pwd_command,
4853 source_command, dump_me_command, editing_info,
4854 set_history_size_command, set_history, show_history,
4856 stack.c (locals_info): ditto
4857 target.c (target_files_info): ditto
4858 valprint.c (set_input_radix, set_output_radix): ditto
4860 * core.c: Remove old variables for handling core and exec file
4861 sections (data_start, data_end, stack_start, stack_end,
4862 reg_stack_start, reg_stack_end, reg_stack_offset, text_start,
4863 text_end, exec_data_start, exec_data_end, text_offset,
4864 exec_data_offset, data_offset, stack_offset). They're
4865 superseded the more general build_section_table and
4867 (get_exec_file): Mention the `file' command.
4868 (read_memory_check): Rename to memory_error, and only call it
4869 in the case of an actual error.
4870 (read_memory, write_memory): call memory_error.
4871 (core_fetch_registers): Register section name is ".reg".
4873 coredep.c: Remove a bunch of crud now that all this file does
4874 is pull the registers out of a core file.
4875 (fetch_core_registers): Rewrite to actually work, I hope.
4877 dbxread.c: Use a.out.gnu.h, not system a.out, now.
4878 Replace index() with strchr(). Remove all the pre-BFD macro
4879 definitions for accessing the symbol file.
4880 (struct dbx_symfile_info): Encapsulate the information that
4881 dbx_symfile_init needs to pass to dbx_symfile_read in this
4884 (dbx_new_init, dbx_symfile_init, dbx_symfile_read,
4885 dbx_symfile_discard): Rearrange symbol file reading to divide
4886 the format-specific part from the format-independent part,
4887 leaving the format-independent part such as file name expansion
4888 and opening in symtab.c. This replaces
4889 partial_symbol_file_open and partial_symbol_file_read.
4890 Symbol_file_read, add_file, add_file_target_command,
4891 add_file_addr_command move to symtab.c. Pass an explicit
4892 "mainline" flag for when reading the main symbol table, rather
4893 than relying on the offset address to be zero or nonzero.
4895 (dbx_symfile_read): Don't allow void *'s to be printed as
4897 (SWAP_SYMBOL): Use bfd routines to byte-swap the symbols.
4898 (ADD_PSYMBOL_TO_LIST): Make the "function call rather than
4899 macro" debug version really work.
4900 (read_dbx_symtab): Remove unref'd parameter inclink.
4901 Avoid swapping N_SLINE symbols, for speed.
4902 Merge N_TEXT!N_EXT case with the other external symbol
4903 definitions' case. Add comments.
4904 (start_psymtab): Allocate the symfile name in the psymtab on
4905 the psymbol_obstack, rather than using the caller's storage.
4906 (end_psymtab): Only allocate a dependencies list if there are
4908 (psymtab_to_symtab_2): Use BFD when reopening file to read
4909 its symbols for real.
4910 (read_struct_type): Add FIXME comments where it needs work
4912 (read_huge_number): Add FIXME about overflows.
4913 (read_range_type): Add FIXME about comparing a long to 1<<32.
4915 * coffread.c: Minor changes to move things closer to the new
4916 regime with symtab.c and dbxread.c Major work is still needed
4919 * exec.c (exec_file_command): Remove old variables (see core.c
4921 (xfer_memory): If memory transfer is right at the end of a
4922 section, don't lose.
4924 * findvar.c (get_saved_register): If value is in a real
4925 register, LVAL is lval_register, not lval_memory.
4927 frame.h: Declare print_sel_frame and record_selected_frame.
4929 gdb-int.texinfo: New file, for GDB internals documentation.
4930 Very simple, unformatted doc of cleanups is there for now.
4932 gdbcore.h: Remove obsolete variables that described a.out
4933 section addresses and offsets. (See core.c above.)
4934 Declare fetch_core_registers and registers_fetched.
4936 getopt.c: Declare char *alloca(); even on SPARC.
4938 infcmd.c (run_command): Call target_kill rather than
4940 (step_command, next_command, stepi_command, nexti_command):
4941 Declare from_tty parameter even though we don't use it.
4942 (run_stack_dummy): argument BUFFER is a char array, not
4943 a pointer to REGISTER_TYPE.
4944 (finish_command): using_struct_return needed a value *,
4945 not a struct symbol *.
4947 * infptrace.c (child_xfer_memory): To avoid dependency on
4948 where sections are in memory, try PT_WRITE_D and if that fails,
4949 try PT_WRITE_I. Most Unixes don't care which you use.
4951 * infrun.c (step_resume_break_shadow): Change to array to
4952 match other breakpoint shadow storage.
4953 (clear_proceed_status): Pass address of bpstat to
4954 bpstat_clear, not the bpstat itself.
4955 (child_create_inferior): FIXME comment about if the child
4957 (start_inferior): Remove old function.
4958 (child_open): Use target_kill rather than kill_inferior.
4959 (wait_for_inferior): Ditto.
4960 (insert_step_breakpoint, remote_step_breakpoint): Use
4961 new step_resume_break_shadow.
4963 * inftarg.c (child_wait): If all child processes die,
4964 pretend that the one being waited for exited with signal 42.
4966 * main.c (command_line_input): When scanning for comments,
4967 don't coredump on unclosed quotes.
4968 (quit_command): Use target_kill rther than kill_inferior.
4969 (_initialize_main): Rename class_user from "user" to
4972 * printcmd.c (print_command_1): Initialize "fmt" if no format
4973 is specified by the user.
4974 (print_frame_args): Only add to args_printed if we are
4975 actually fetching args from the stack (avoiding undefined
4977 (_initialize_printcmd): Remove bogus \{ from string.
4979 * remote-eb.c (eb_open): Avoid coredump on no argument.
4981 * remote-nindy.c: Bring out of Intel environment into new
4982 target environment. Remove all conditional compilation on
4983 I80960. Massive hacking throughout.
4984 (nindy_xfer_inferior_memory): New routine stolen from
4986 (nindy_create_inferior): New routine pieced together, probably
4987 not quite working yet.
4988 (nindy_ops): New target_ops struct for nindy.
4990 * remote-vx.c: Use write_memory rather than target_write_memory
4991 to get error checking.
4992 (vx_add_file_command, vx_open): Use symbol_file_add rather than
4994 (vx_create_inferior): Use target_terminal_ours...
4996 * signame.c (_initialize_signame): Always initialize, since
4997 we need the table for things other than psignal.
4999 * solib.c (solib_add): Use symbol_file_add, not add_file.
5000 (solib_address): Return boolean result rather than struct
5001 pointer which nobody else knows the type of.
5003 * sparc-tdep.c, valops.c: Use write_memory rather than
5004 target_write_memory, to get error checking.
5006 * stack.c (locals_info, catch_info, args_info,
5007 get_selected_block, frame_command, up_command): Use
5008 target_has_stack, rather than have_inferior_p or
5011 * sun3-xdep.c (fetch_core_registers): Rewrite for new BFD regime.
5013 * symfile.h: New file, defining the interface between the
5014 generic and object-file-specific symbol reading code.
5016 * symtab.c: Move generic symbol-reading interface to symtab.c,
5017 from dbxread.c, coffread.c, mipsread.c, etc. Add symtab_fns
5018 table to map BFD targets to symbol-reading modules in GDB.
5019 Change index to strchr.
5020 (lookup_struct_elt_type): Use error() rather than hand-made
5021 simulations thereof.
5022 (lookup_partial_symbol): Speedup slightly when length == 0.
5023 (symbol_file_add): New function.
5024 (symbol_file_command): Call it.
5025 (symfile_open, symfile_init): New function.
5026 (add_file_target_command, add_file_addr_command): moved from
5029 * target.c (target_command): use target_kill.
5031 * target.h (target_files_info): Don't declare, never called
5034 * tm-sun2.h, tm-sun3.h (STACK_END_ADDR): Use system include
5035 files to determine stack end address.
5037 * valarith.c (value_x_binop, value_x_unop): Change error message
5038 to be more useful. Pass proper argument to value_struct_elt.
5040 * valops.c (value_assign): FIXME comment that long long
5041 bitfields will break here.
5043 * Makefile.dist: Add symfile.h, remote-nindy.c, remote-eb.c.
5044 Update `make saber_gdb' to work better.
5046 * TODO: A woman's work is never done.
5048 * cplus-dem.c, environ.c, inferior.h, infrun.c, inftarg.c,
5049 main.c, obstack.c, printcmd.c, remote-eb.c, remote-nindy.c,
5050 remote-vx.c, remote.c, solib.c, source.c, sparc-pinsn.c,
5051 sparc-tdep.c, sparc-xdep.c, symmisc.c, symtab.c, symtab.h
5052 target.c, terminal.h, tm-sparc.h, tm-sunos.h, utils.c,
5053 valops.c, valprint.c, exec.c: Lint.
5056 Wed Dec 12 23:44:15 1990 John Gilmore (gnu at cygnus.com)
5058 Continuing Intel 960 port merge of GDB.
5060 * Makefile.dist: Merge i960 "nindy-share" files. Rename
5061 malloc.h to gmalloc.h to avoid name conflicts in /usr/include.
5062 Don't ship gdb.dvi in tar file. Link gdb with init.o, not init.c.
5063 Wack over "make depend" so it handles files in subdirectories
5064 vx-share, nindy-share, bfd, and in the current directory.
5066 * blockframe.c (get_prev_frame_info): Remove fatal error
5067 if stack not defined.
5069 * core.c (core_open, core_detach): New functions that handle
5070 the old "core-file" command as "target core" and "detach" instead.
5071 (core_file_command): Call them.
5072 (core_xfer_memory): Use common routine xfer_memory.
5074 * dbxread.c: Include a.out.gnu.h, not system a.out.h.
5075 dbxread now uses bfd for everything but symbol reading itself.
5076 BFD internals are used to drag out the relevant file offsets.
5077 (partial_symbol_file_open): Change args all around for BFD.
5079 * symtab.c: Rename "value" to "val" everywhere, so we can
5081 (symbol_file_command): New command, moved from dbxread.c
5082 and coffread.c. It uses BFD to read the file, then vectors
5083 based on its type, to dbx or coff symbol readers.
5084 * symtab.h: Extern a few vars for symbol_file_command.
5086 * target.h: Breakpoint takes a char * save area, not a char **.
5088 * valprint.c (val_print): When unpacking bitfields, offset
5089 the address in gdb of the value, if it is declared with a shorter
5090 type. Remove the last "runtime kludge test" of host byte order.
5092 * utils.c: Remove old my_bfd_read routine.
5094 * stack.c (frame_info): Use target_has_stack. Print program counter
5095 register's actual name rather than "pc", since it's called the
5096 "ip" (instruction pointer) on the i960 (sigh).
5098 * target.c (target_command): Add command for selecting a target
5099 type and calling its open routine. This is used for initiating
5100 communication with a particular target, in a generic way.
5102 * tm-i960.h: Update for modern gdb. Remove semicolons from
5103 various macros. Handle reading struct return convention, and
5104 error-out attempts to return structs with the "return" command.
5105 Be sure gdb doesn't think we know how to call functions in the
5108 * i960-tdep.c: Rename FRAME_CHAIN_VALID and FRAME_FIND_SAVED_REGS
5109 to i960_xxx in lower case.
5110 (arg_address): Circumvent errors due to LOC_ARG_BLOCK
5111 not being defined yet.
5113 * remote.c (remote_open): Call start_remote to initialize
5114 wait_for_inferior during open.
5115 (remote_xfer_inferior_memory): Return length written rather
5118 * remote-vx.c (target_command -> vx_open): Use new generic
5120 * remote-eb.c, inftarg.c, exec.c: ditto.
5122 * infrun.c: Fix comments.
5123 (attach_program -> child_open): Use new generic target command.
5124 (wait_for_inferior): Clear saved register values before target_wait,
5125 so target_wait can set some of them if convenient.
5127 * infptrace.c (fetch_inferior_registers, store_inferior_registers):
5128 Return success indicator, not void.
5129 (child_xfer_memory): Avoid fetching initial word if we'll
5130 overwrite it anyway.
5132 * infcmd.c (attach_command): Use new generic target open routine.
5133 (_initialize_infcmd): Update doc on attach and detach commands.
5134 (do_registers_info): Merge in a byte-order problem as a FIXME
5137 * findvar.c (find_saved_register): Avoid problem in current frame.
5138 (read_relative_register): Ditto.
5139 (write_register): Convert byte order on the way out.
5141 * exec.c (file_command): Add.
5142 (add_to_section_table, exec_command): Use new bfd_map_over_sections.
5143 (xfer_memory): Common function between core_xfer_memory and
5145 (exec_xfer_memory): Use it.
5147 * pn-opcode.h: Document that a "PN" is a Gould PowerNode.
5149 * breakpoint.c, breakpoint.h, symtab.h, value.h, frame.h, utils.c,
5150 valops.c, stack.c, target.c, sparc-xdep.c, source.c, printcmd.c,
5151 infcmd.c, i960-pinsn.c, eval.c, defs.h: lint and gcc -Wall.
5153 Sun Dec 2 16:45:06 1990 John Gilmore (gnu at cygnus.com)
5155 Merge Intel 960 port of gdb, continuing...
5157 * dbxread.c (partial_symbol_file_open, partial_symbol_file_read,
5158 symbol_file_command): Pass from_tty arg to hush 'em up.
5160 * coffread.c (symbol_file_command): Avoid output if from_tty != 1.
5161 Add magic numbers for 960 COFF format.
5163 Fri Nov 30 09:18:20 1990 John Gilmore (gnu at cygnus.com)
5165 Merge Intel 960 port of gdb, from Intel "1.2" release.
5167 CHANGE_LOG entries from their port, which was based on
5170 Thu Sep 6 11:02:22 PDT 1990
5171 Remove temp file if download is interrupted.
5173 Wed Aug 1 09:08:33 PDT 1990
5174 Now uses binary protocol to talk to NINDY.
5175 Old hex protocol (NINDY 2.13 and older) supported with -O switch.
5176 Times out after 5 seconds when trying to talk to NINDY.
5178 Tue May 29 12:54:49 PDT 1990
5179 Added variable baud rate (-b switch).
5180 Source code reorganization.
5182 Thu Apr 26 11:09:55 PDT 1990
5183 More cleanup of batch mode; specifically, execute "-s", "-e", and
5184 "-se" switches as soon as they are encountered on the invocation line.
5186 Fri Apr 20 13:47:15 PDT 1990
5189 Thu Apr 19 09:54:28 PDT 1990
5190 Add 'reset' command.
5192 Wed Apr 18 09:48:07 PDT 1990
5193 After opening remote tty, wait for 1 second to go by without input
5194 from it before trying to talk to NINDY (fixes problems with the
5195 Heurikon HK80/V960E).
5197 Mon Apr 4 16:33:05 PDT 1990
5198 Some output was not being suppressed in 'batch' mode.
5200 Thu Mar 22 15:31:11 PST 1990
5201 Ask user if old symbol table should be deleted when new file is
5204 Allow user to run a program downloaded before gdb960 was brought up.
5206 Correct "exec-file" help message for i80960 context.
5208 Correct bug in calculating user space address: could occasionally
5209 corrupt user program.
5211 Make sure to zero low-order bits in rip's because of bug in 960CA
5212 A-step part: could cause operation faults when "next"ing across
5215 Correct bug that made it impossible to get source line numbers for
5216 code loaded at addresses higher than 0x7fffffff.
5218 Wed Jan 10 12:43:22 PST 1990
5219 Open remote tty for exclusive use.
5221 Fri Jan 5 12:14:42 PST 1990
5222 Correct disassembly (CA manual was right after all):
5223 opcode for sysctl is 0x659
5225 Mon Oct 23 12:03:04 PDT 1989
5226 Use G960BASE and G960BIN environment variables to find 'sx' utility.
5228 Mon Oct 16 14:15:09 PDT 1989
5229 "sfr0"-"sfr31" should have been named "sf0"-"sf31"
5231 Mon Oct 2 15:56:31 PDT 1989
5233 Added 960CA disassembly support.
5235 To simplify maintenance:
5236 - eliminated use of symblic links on pinsn.c: use i960-pinsn.c
5238 - eliminated opcode.h: incorporates tables into i960-pinsn.c
5239 - moved 960-specific routines from i960-pinsn.c to i960-md.c
5240 - made disassembly interface identical to that in gdmp960.
5244 Wed Nov 28 21:32:48 1990 John Gilmore (gnu at cygint)
5246 * target.h: Allow targets to stack. Add target_has_memory,
5247 _registers, etc. Restructure memory access and "info files"
5248 to walk the target stack.
5249 * exec.c, core.c, inftarg.c, remote.c, remote-vx.c, remote-eb.c,
5250 target.c: Change tables to match target.h.

5255 * remote-eb.c: New memory regime, new info files.
5256 * remote-vx.c: New memory regime, new info files. Now use
5257 separate targets for VxWorks attachment to machine, and
5258 actually running a process under VxWorks, since one has
5259 stack & execution & regs and the other doesn't.
5260 * remote.c: New memory regime, new info files.
5261 * sparc-xdep.c (fetch_core-registers): New memory regime.
5262 * target.c: New routines and support for stacked targets,
5263 new memory regime, new info files regime.

5267 including use of the new BFD (binary file) library.
5268 * gdbcore.h: Add struct section_table.
5269 * exec.c (build_section_table): Iterate all sections and
5270 record what gdb needs to know about them.

5277 * dbxread.c: Quick changes to make it compile with new BFD.
5278 * utils.c (error): Avoid using bfd_error in generic routines.
5280 * core.c (core_fetch_registers): Get from the ".regs" section of
5282 * sparc-xdep.c (fetch_core_registers): Use the .regs info.
5284 * inferior.h (attach_flag): Export.
5285 * infcmd.c (run_command): use new target_create_inferior.
5286 * infrun.c (child_create_inferior): Don't return result.

5292 since been deleted, such as temporary breakpoints.
5293 infcmd.c (program_info): ditto.
5295 * core.c (core_file_command): Display the frame where the core
5300 * remote-vx.c (target_command): Merge in target command from
5301 targ-vx.c. A few other cleanups.
5303 * TODO, Projects: Lots more stuff to do...
5305 Fri Nov 23 18:15:38 1990 John Gilmore (gnu at cygint)
5307 Massive changes to wall off the remote-debugging interface
5308 behind a function vector. The port to handle VxWorks targets
5309 is also part of this.
5311 All files: Replace references to renamed functions,
5312 remove references to remote_debugging, remove references to
5313 have_include_file, have_core_file in favor of target_has_stack,
5314 target_has_memory, etc.
5316 * Modularize the breakpoint interface.
5317 breakpoint.h (BREAKPOINT_MAX): New define sets max length of
5318 a breakpoint instruction.
5319 breakpoint.c: struct breakpoint's shadow_contents now sized as
5321 (insert_breakpoints): Vector to target to install breakpoints.
5322 (remove_breakpoints): Vector to target here too.
5323 Remove REMOTE_SA_SPARC kludges and other remote_debugging.
5324 sparc-tdep.c (single_step): Use new breakpoint interface for
5325 the single-step breakpoints.
5326 mem-break.c (memory_insert_breakpoint, memory_remove_breakpoint):
5327 New file, contains routines to insert and remove breakpoints by
5328 reading out the old contents and later replacing them. This is
5329 how ptrace breakpoints work, and many remote systems as well.
5331 * tm-vxworks68.h: New config file, overrides a few things for
5332 Wind River's preferences.
5334 * target.h: New file, for transfer vector used to talk to the
5335 inferior (child, attached, core, exec, remote, etc). All accesses
5336 to the thing being debugged should come through these vectors.
5337 target.c: New file, routines to handle transfer vector.
5338 (various files): Add transfer vectors XXX_ops for the various
5339 targets and pseudo-targets (core files, etc) we support.
5341 * breakpoint.c (bpstat_stop_status): Further explorations of
5342 watchpoints and why things don't work all the time.
5343 (bpstat_alloc): New fn to allocate a bpstat and chain it.
5345 * config.gdb: Only add "source ${srcdir}/.gdbinit" to
5346 the local gdbinit if it doesn't already have it.
5348 * core.c (core_ops): add and install.
5349 Allow core debugging without exec file.
5351 * dbxread.c (free_and_init_header_files): Merge two fns.
5352 (end_symtab): Free named symbol table when a new version comes in.
5353 (read_dbx_symtab): Relocate all kinds of symbols with base
5354 address. First step toward handling different text, data, bss
5356 (add_file_addr_command): Renamed add_file_command.
5357 (add_file_command): Vector to remote handler.
5358 Add "load" as an alias for "add-file" command.
5360 * defs.h: Allow "volatile" to be used in non-ANSI; use it for
5361 non-returning functions.
5363 * exec.c: Add exec_ops, and push it as a target when an exec
5366 * infcmd.c (run_command): Pass executable file name and arg list
5367 separately when starting an inferior. Permit "run" when no exec
5368 file is specified, for VxWorks.
5369 (detach_command): Move to child_detach in inftarg.c.
5371 * inftarg.c: New file. Unix-child-specific routines, and the
5372 child_ops structure.
5374 * inferior.h (registers): Export "registers" as the way for
5375 target dependent register handlers to find gdb's local copy of
5376 the registers. Rename "stop_after_attach" to "stop_soon_quietly"
5377 since it is now used by places that want wait_for_inferior to
5378 handle the grunge but want to see every trap from the inferior.
5380 * inflow.c (create_inferior): Pull out, and merge into infrun.c.
5381 Eliminate remote_debugging hooks in terminal handling.
5383 * infrun.c: Replace start_inferior with child_create_inferior.
5384 Move all the hair of Unix shells and ptrace idiosyncracies into
5385 child_create_inferior, so remote handlers don't have to deal.
5386 Remove running_in_shell. Rename stop_after_attach to
5387 stop_soon_quietly, and use it in a few other places where we want
5388 to just call wait_for_inferior and get control back on the first
5389 trap. trap_expected now never takes a value > 1.
5390 (init_wait_for_inferior): Initialize static vars when a new
5393 main.c (gdbinit): Add new hook for .gdbinit file name, let
5394 it be overridden by config files as GDBINIT_FILENAME.
5395 (DEFAULT_PROMPT): Add new hook for overriding (gdb) prompt.
5396 Both of these are used for VxWorks gdb.
5398 mcheck.c: rename include file "gmalloc.c" to avoid problems
5399 with system include file "malloc.c".
5401 param-no-tm.h: New include file, same as param.h but does not
5402 include the default "tm.h" file. This is used in files where
5403 the target is known, e.g. remote-eb.c or sparc-xdep.c.
5405 param.h: Now just a shell that includes tm.h and param-no-tm.h.
5407 remote-vx.c: New file, VxWorks remote debugging support. Uses
5408 RPC routines that are shared with the target system, in directory
5411 remote.c: Vectorize remote interface.
5413 source.c: Globalize source_path, and make an alias "l" for "list"
5414 since we now have the "load" command.
5416 sparc-xdep.c: Use new param-no-tm.h.
5418 symmisc.c (free_named_symtab): Add new function from Wind River.
5419 However, ifdef it out for now while we think about what it should
5422 tm-sun3.h, xm-sparc.h, xm-sun3.h, xm-symmetry.h: Move
5424 the xm- file, and change its name to CHILD_PREPARE_TO_STORE, since
5425 non-Unix-children handle this with their own code in the target
5428 Makefile.dist: Roll version to 3.92.3. Add vx-share stuff to
5429 source and target lists. Add vx-share to default list of include
5430 directories. Add new files to src and target lists: mem-break,
5431 target, inftarg, remote-eb, remote-vx, targ-vx. Be sure the
5432 ${srcdir} versions of munch and createtags are used.
5434 * valops.c (find_function_addr): Split out of call_function.
5435 (call_function_by_hand): Rename call_function; this function
5436 calls functions in the target by laboriously patching the target
5437 word-by-word with the right stack, args, regs, etc.
5440 Mon Nov 5 17:29:10 1990 John Gilmore (gnu at cygint)
5442 Handle AMD 29000 a bit better.
5444 * remote-eb.c (readchar): Mask received char log to make it readable.
5445 (remote_start): Pass arguments down to executing program.
5446 Make startaddr unsigned.
5447 infrun.c (start_inferior): Accept args, pass them to
5449 infcmd.c (run_command): Pass args down to start_inferior.
5451 * tconfig/am29k-aout, tconfig/am29k-coff: New files specifying
5452 the target object file format.
5453 tm-29k.h: Pay heed to COFF_ENCAPSULATE.
5455 * am29k-pinsn.c (print_insn): Print 0x on hex numbers in disassembly.
5456 am29k-tdep.c (examine_prologue): Better checking of function prefixes.
5458 Sun Oct 7 18:20:45 1990 John Gilmore (gnu at cygint)
5460 * Makefile.dist (VERSION): Roll version to 3.91.9 and freeze.
5461 * TODO: We did a few things, we have more to do though.
5463 * xm-sparc.h (CLEAR_DEFERRED_STORES): Define.
5464 * inflow.c (inferior_died): Clear deferred stores.
5466 * Debug problems with dummy frames and calls to the inferior.
5467 * tm-sparc.h (PUSH_DUMMY_FRAME, POP_FRAME): Move to sparc-tdep.c.
5468 * sparc-tdep.c (do_restore_insn): Simplify.
5469 (sparc_frame_find_saved_regs): Simplify and fix what we find.
5470 (sparc_push_dummy_frame): Simplify and fix what we push.
5471 (sparc_pop_frame): Slightly more hair here, deciding whether
5472 we are restoring a saved PC or returning to a return address in %i7.
5473 * sparc-xdep.c (read_inferior_registers): Debug if valid reg is read.
5475 * utils.c (xmalloc, xrealloc): Return type depends on __STDC__.
5476 * symtab.h (xmalloc): ditto, for obstack_chunk_alloc.
5477 * obstack.h (chunkfun): ditto.
5478 * defs.h (xmalloc, xrealloc): ditto
5480 * utils.c (quit): Grab the terminal from the child if necessary.
5482 * inflow.c (term_status_command): Rename to term_info, change
5485 * sparc-pinsn.c (print_insn): Disassembly prefers real instructions.
5486 (is_delayed_branch): Speed up.
5487 * sparc-opcode.h: Add ALIAS bit to aliases. Fix up opcode tables.
5488 Still missing some float ops, and needs testing.
5490 * Support for input and output radixes other than base 10
5491 * defs.h (input_radix, output_radix): Declare.
5492 * expread.y (yyparse, parse_number): Handle changes of input
5493 radix, and ambiguous names-or-numbers in radixes >10.
5494 * printcmd.c (print_scalar_formatted): Print formatted hex
5495 numbers in varying column widths.
5496 * valprint.c (val_print): Use output_format to print scalar ints.
5497 (set_input_radix, set_output_radix, set_radix): Create.
5498 (set_output_radix): Set output_format from output_radix.
5499 (_initialize_valprint): add `set radix' but leave the others off.
5501 * main.c (execute_command): Let stupid questions be turned off.
5502 (_initialize_main): Handle "set stupidity", etc.
5504 * main.c, inflow.c, inferior.h, frame.h, command.c, defs.h,
5505 sparc-pinsn.c, sparc-xdep.c, value.h, valops.c, values.c: Lint.
5507 Tue Oct 2 11:20:02 1990 John Gilmore (gnu at cygint)
5509 * TODO, Makefile.dist, ChangeLog: Freeze for 3.91.8 release.
5510 bfd stuff is still screwed up, but with some manual work, it
5513 * breakpoint.c (bpstat_do_actions): Start over if a command
5514 proceeds the inferior, since the inferior will have stopped and
5515 will need to have its new stop-actions taken care of.
5517 * dbxread.c (read_struct_type): Expression gives Sun3 4.0.3
5518 compiler fits, simplify it.
5520 * gdb.texinfo (directory command): Doc new dir command.
5521 source.c (directory_command): "dir" now puts things on the front
5522 of the path, moves dups up front, and handles multiple names
5523 on the command line, inserting each one in order. It also
5524 blows away cached line and full_filename info.
5526 * stack.c (backtrace_command): Skip "more stack frames follow"
5529 * Change #ifndef HAVE_VPRINTF to #define MISSING_VPRINTF in
5530 xm-convex.h, xm-hp300bsd.h, xm-isi.h, xm-merlin.h, xm-news.h,
5531 xm-np1.h, xm-pn.h, xm-pyr.h, xm-symmetry.h, xm-umax.h, xm-vax.h.
5532 The only odd one was Gould NP1, which had defined vprintf to
5535 * Merge Ted Goldstein <tedg@Eng.sun.com>'s changes for epoch.
5536 printcmd.c (print_command_1): Pass 'inspect' flag down as a global
5537 variable, inspect_it.
5538 valprint.c (print_string, val_print): Use the global inspect_it
5539 to indicate whether to print in Epoch style or normal style.
5541 Mon Oct 1 23:55:26 1990 John Gilmore (gnu at cygint)
5543 * printcmd.c (call_command): add an alias for the "print" command
5544 which runs expressions and doesn't print the result if void.
5545 (print_command_1): implement it.
5547 * command.c: Remove #if 0'd code. Initialize all the fields
5548 in add_cmd (). Rename do_nothing_command to
5549 not_just_help_class_command, and make it externally visible.
5550 command.h: add user_commands to struct.
5551 * main.c (define_command): Don't overload c->function with a char
5552 string as well as a function pointer.
5554 * eval.c (evaluate_subexp): Reinstall tiemann changes to
5555 calling convention of value_struct_elt () that got dropped in
5558 * tm-sparc.h (FRAME_FIND_SAVED_REGS): move to sparc-xdep.c.
5559 sparc-tdep.c (sparc_frame_find_saved_regs): ditto.
5561 * tm-sparc.h (POP_FRAME): replace some constants with defines.
5563 * sparc-xdep.c (store_inferior_registers): defer stores to regs
5564 until a good time (e.g. when we are about to run the child),
5565 saving ptrace calls.
5566 * infrun.c (proceed): handle DO_DEFERRED_STORES.
5567 * tm-sparc.h: define DO_DEFERRED_STORES.
5569 * sparc-xdep.c (store_inferior_registers): when storing float
5570 registers, don't store stack regs too. When storing the SP,
5571 however, DO store the stack regs too. This fixes a bug in which
5572 the dummy frame is not recognized when a call_function finishes,
5573 because its frame pointer (in the stack regs) was never
5575 (read_inferior_registers): Mark WIM and TBR and FPS and CPS valid
5576 even though we don't know how to read them from an inferior.
5577 valops.c (call_function): Comment about storing SP.
5579 * infrun.c (save_inferior_status): Save away the original bpstat
5580 chain so it can be restored later. Install the copied version for
5581 use by whoever saved the status. It will be blow away by
5582 restore_inferior_status, and the original chain restored. This is
5583 important for people who have pointers into the original.
5585 * breakpoint.c, command.h, copying.awk, dbxread.c, defs.h,
5586 findvar.c, frame.h, obstack.h, obstack.c, inflow.c, value.h,
5587 main.c, printcmd.c, sparc-tdep.c, symtab.c, valprint.c: lint
5590 Fri Sep 28 20:32:46 1990 John Gilmore (gnu at cygnus.com)
5592 * Makefile.dist: Roll version to 3.91.8. Add bfd.h and bfdconfig.h
5593 temporarily to the makefile. Add am29k-opcode.h and WHATS.NEW.
5594 Add stuff.c and kdb-start.c to the OTHERS list for tar files.
5596 Fri Sep 28 19:12:12 1990 John Gilmore (gnu at cygint)
5598 * Merge Mike Tiemann's multiple inheritance changes from Sun.
5599 Store the baseclasses in a type struct starting from array element
5600 0 rather than from the unusual array element 1.
5602 dbxread.c: the above.
5603 (virtual_context): Add
5604 Read new debug information about which virtual function table
5605 a virtual function is from, and store it in fn_field.fcontext.
5607 symtab.h: Add fcontextt. Fix baseclass indices. Typo in
5608 TYPE_FN_FIELD_STATIC_P.
5610 symtab.c: the above.
5611 valops.c: the above. Handle pointer casts of object *'s.
5612 (search_struct_method): Add.
5613 (value_struct_elt): First arg is now a pointer to a value, and is
5616 valprint.c: the above.
5617 values.c (value_virtual_fn_field): Add type arg. Handle
5618 offsetting to the proper object when calling virtual fns.
5620 (baseclass_addr): Add valuep arg.
5622 * README: Document the current state of BFD config (missing).
5623 * TODO, ChangeLog, Makefile.dist: Roll version.
5624 * WHATS.NEW: Add summary of changes since 3.5.
5626 Thu Sep 27 16:23:12 1990 John Gilmore (gnu at cygint)
5628 * dbxread.c (read_struct_type): Clear bit vectors whenever
5630 symtab.c (B_CLRALL): define.
5632 * tm-sparc.h (STORE_RETURN_VALUE): Avoid clobbering types by
5633 using == rather than =. Huh... This fixes the dreaded problem
5634 wherein builtin_type_int becomes TYPE_CODE_FLT.
5636 * core.c (info_files): Show the inferior pid.
5638 * config.gdb: Avoid putting "dir" command into .gdbinit. GDB
5639 already knows how to look in the source directory.
5641 * Remove psymtab hair from many places. Remove duplicated code
5642 for searching symbol tables. Hide psymtabs from most places.
5643 Make it fast to get from a psymtab to its symtab.
5645 blockframe.c (blockvector_for_pc): Remove psymtab hair.
5646 coffread.c (psymtab_to_symtab): Rename to psymtab_to_symtab2.
5647 mipsread.c (psymtab_to_symtab): Rename to psymtab_to_symtab2.
5648 dbxread.c: export psymtab_to_symtab, make it work if called N times.
5649 (psymtab_to_symtab): Rename to psymtab_to_symtab2. Initialize
5650 new symtab completely. New psymtabs get symtab pointer
5651 initialized to zero. Remove MI warning printf.
5652 symtab.h: Comments. Add psymtab to symtab pointer.
5653 (PSYMTAB_TO_SYMTAB): New macro.
5654 symtab.c: use PSYMTAB_TO_SYMTAB. Add psymtab_to_symtab and export it.
5655 source.c: use PSYMTAB_TO_SYMTAB. Remove symtab version and
5657 stack.c (backtrace_command): Avoid pre-pass to read symbols, if
5659 (print_frame_info): Avoid special-casing symbols that have not yet
5662 * source.c (open_source_file): Quick path if we have already
5663 located the source file by its full name.
5665 * symtab.c (lookup_symbol): Use find_pc_symtab rather than
5666 find_pc_psymtab. When a name is found in the misc function
5667 vector, search the symbol table for its mangled name, not the
5668 name that the user typed.
5670 * bfd.h: Fix missing comment terminators, make #endifs match.
5672 * valarith.c (value_less): Handle unsigned int comparisons.
5673 Add FIXME about pointer compares, which assume host and target
5674 pointers are the same.
5676 * command.c (do_nothing_command): lint
5677 dbxread.c: lint. Remove sort_syms. Document C++ visibility info,
5678 fix comments on debug symbol format for visibility. Actually set
5679 visibility of symbols.
5680 main.c (echo_command): lint; use <readline/history.h>.
5681 tm-sparc.h (FRAME_FIND_SAVED_REGS): lint
5682 obstack.h (_obstack_blank): Rearrange pointer math to avoid
5683 pointing past end of allocated memory; saber complains.
5684 obstack.h: Declare the external functions that we use.
5685 valarith.h: use <string.h>
5686 solib.c (solib_add): lint.
5688 Fri Sep 21 17:05:19 1990 John Gilmore (gnu at cygint)
5690 * main.c (initialize_main): Default info_verbose to off, now that
5691 symbol reading is fast.
5692 (quit_command): Avoid clobbering exec_bfd while quitting.
5694 * Initial BFD (binary file diddling library) merger:
5695 coffread.c: Change AOUTHDR to struct exe_hdr.
5697 core.c: initialize initialized data at compile time.
5698 (core_file_command): Move from coredep.c, convert to bfd.
5699 (xfer_core_file): Convert to bfd.
5700 exec.c (exec_file_command): use bfd routines.
5702 mips-tdep.c: Remove exec_file_command and friends.
5705 * coredep.c: (fetch_core_registers) Convert core_file_command to
5706 fetch_core_registers.
5707 mips-xdep.c, sparc-xdep.c, sun3-xdep.c: ditto.
5709 * utils.c: (error): Bogus crap, FIXME, to print bfd errors.
5710 (my_bfd_read): More bogosity, which I don't think we call.
5711 (program_name): Remove this atrocity asap!
5713 Wed Sep 19 13:36:41 1990 John Gilmore (gnu at cygint)
5716 values.c: allocate_repeat_value was not clearing the
5717 optimized_out field.
5718 (value_static_field): minor stylistic fix (wrong macro was used).
5719 valops.c (value_struct_elt_for_address): didn't work for C++
5722 * signame.c (_initialize_signame): Initialize signal names once.
5724 * breakpoint.h, command.c, copying.awk, defs.h, environ.c,
5725 exec.c, frame.h, infcmd.c, inferior.h, main.c, munch, sun3-xdep.c,
5726 symtab.h, tm-29k.h, valprint.c, value.h, values.c: Lint.
5728 * remote-eb.c: Support user-settable baud rates on the serial port.
5730 * tm-sun3.h (PREPARE_TO_STORE): fix typo.
5732 Fri Sep 14 13:28:29 1990 John Gilmore (gnu at cygint)
5734 * tconfig/sun3os4: Remove warning about native assembler,
5735 since it also occurs in the xconfig file.
5737 * findvar.c (registers): Allocate some slop after `registers'
5738 to prevent stray accesses from trashing the next variable.
5740 * tm-68k.h (REGISTER_BYTES): Allocate the right number of bytes
5741 on the sun-3, by changing the #ifdef from `sun3' (which is not
5742 defined by cc) to `sun'. Symptom was trashed builtin_type_XXX
5743 vars, which happened to follow `registers' in the executable.
5745 * readline/history.c (history_search): Heed gcc-2's advice
5746 and parenthesize && inside ||).
5748 * am29k-opcode.h, am29k-pinsn.c, am29k-tdep.c, remote-eb.c,
5749 tm-29k.c: Insert FSF copyright headers.
5751 * remote-eb.c: Better comments.
5753 * Makefile.dist: Update to 3.91.6.
5754 * TODO: note PREPARE_TO_STORE problem.
5756 Thu Sep 13 09:52:33 1990 Jim Kingdon (kingdon at cygint)
5758 * stack.c (frame_info): Only use FRAME_FIND_SAVED_REGS if defined.
5760 * remote.c: Wrap the whole file in #if !defined (SPECIAL_REMOTE).
5762 * infrun.c (wait_for_inferior, at end): Don't set up
5763 prev_* if the inferior no longer exists.
5765 * inferior.h (CALL_DUMMY_LOCATION): New macro, to replace
5766 CANNOT_EXECUTE_STACK.
5767 valops.c (call_function): Use it.
5769 * tm-convex.h: Add CALL_DUMMY_LENGTH for use by PC_IN_CALL_DUMMY.
5771 * inferior.h (PC_IN_CALL_DUMMY): New macro.
5772 infrun.c (wait_for_inferior, 2 places): Use it.
5774 * values.c (value_being_returned): Only use
5775 EXTRACT_STRUCT_VALUE_ADDRESS if defined.
5777 * Move PREPARE_TO_STORE from xm-sun3.h to tm-sun3.h to do the
5778 right thing for remote-eb.c.
5780 * sun3-xdep.c: Remove extraneous call to remote_store_registers.
5781 * sun386-xdep.c, hp300hpux-xdep.c, sparc-xdep.c: Ditto.
5783 * blockframe.c: Put get_frame_saved_regs inside #if !defined
5784 (FRAME_FIND_SAVED_REGS).
5786 * findvar.c ({fetch,store}_registers): Check for
5787 REMOTE_{FETCH_STORE}_REGISTER macro.
5789 * findvar.c (get_saved_register): Add argument lval and
5790 change meaning of argument addr.
5791 findvar.c: Change calls to get_saved_register to reflect
5792 new calling convention.
5793 valops.c (value_assign): Use get_saved_register instead of
5794 find_saved_register.
5796 Sun Sep 2 12:40:20 1990 Jim Kingdon (kingdon at cygint.cygnus.com)
5798 * coffread.c (read_one_sym): Make temp_aux an AUXENT, not
5799 an (uninitialized) pointer to one. Use "&" when passing it
5802 Fri Aug 31 22:57:54 1990 Jim Kingdon (kingdon at cygint.cygnus.com)
5804 * coffread.c (getfilename): Use DGUX x_offset and x_name if
5807 * coffread.c (symbol_file_command): Put semicolon after
5809 Put safe_to_init_tdesc_context in #if defined (TDESC).
5810 Put #ifdef TDESCs in 1st column for non-ANSI cpp's.
5811 coffread.c: #include <sys/stat.h>.
5812 (read_coff_symtab): Typo: in_source_files -> in_source_file.
5813 Add missing ')' in check for "lc%" and friends. Remove
5815 Declare read_one_sym() at top of file.
5816 (read_file_hdr): Put in extra #ifdefs so MC68MAGIC and
5817 MC68WRMAGIC can have the same value without causing a duplicate
5820 Thu Sep 13 15:55:36 1990 John Gilmore (gnu at cygint)
5822 * Allow a Makefile to be built without building the
5823 tm and xm file links that screw up builds in subdirectories.
5824 This is done with `config.gdb none', then you can do things
5825 like `make gdb.tar.Z'.
5826 * tconfig/none: Config file for no target system
5827 * xconfig/none: Config file for no host system
5828 * config.gdb: If no TM or XM files are called out by the
5829 host or target file, don't make links for them.
5831 * cplus-dem.c: Add documentation.
5833 * dbxread.c (read_ofile_symtab): Turn a fatal error into a
5834 simple error, so the user's gdb doesn't crash due to some object
5835 file problem (e.g. somebody is rebuilding the file out from under
5838 * printcmd.c (print_address_symbolic): demangle the symbol.
5840 * Makefile.dist (OTHERS): Remove tdesc-lib because it has
5841 Motorola copyrights in it. Make "make gdb.tar.Z" work.
5842 (alldeps.mak): sort and uniq all results from this; duplicates
5843 hose gdb.tar.Z link building. Remove RCS files from
5844 tconfig and xconfig. Add config files for sun386. Add
5845 a few odd files to OTHERS and HFILES.
5847 Mon Sep 10 21:20:24 1990 John Gilmore (gnu at cygint)
5849 * Makefile.dist: Pull solib.c to tconfig/sun?os4.
5850 Roll version number to 3.91.5. Make lint work in bindir.
5852 * README: Document cross-debugging and new file structure.
5854 * blockframe.c: Lint. Include "value.h" to declare read_register.
5855 (find_pc_partial_function): remove duplicate line.
5857 * command.h: Lint. Declare error_no_arg and dont_repeat.
5859 * tm-news.h: Remove inadvertently duplicated stuff.
5861 * mipsread.c: Remove cache_pc_function stuff, now done cleanly.
5862 Clean up usage of misc_function_type. Declare some CORE_ADDRs.
5864 * config.gdb: Allow `config.gdb host target' form. Clean
5865 up previous change that printed bogus messages when you just said
5868 * core.c: #include "command.h" for lint.
5871 * main.c: Remove some casts of enums. Lint.
5878 * printcmd.c (initialize_printcmd): Fix thinko in inspect cmd.
5880 * sparc-tdep.c (isannulled): Take instruction as parameter, don't
5881 read it from memory. This will allow us to save ptrace calls
5882 eventually. Changed caller single_step too.
5884 * sparc-xdep.c (fetch_inferior_registers): Avoid reading regs
5885 that we aren't going to use, saving many ptrace calls, especially
5886 when watchpointing or single stepping. Use some #define's for
5888 (store_inferior_registers): Ditto.
5889 (core_file_command): Use some #define's for constants.
5891 * tm-sparc.h: Add #define's for some register numbers, so we
5892 can eliminate the use of random constants in sparc-xdep.c.
5894 * stack.c (frame_command, print_frame_info, up_command,
5895 down_command) Remove frame_changed, since it
5896 causes a bug and doesn't seem to do anything useful. In some
5897 places it was used as a flag, in others as a stack level (?).
5899 * utils.c: Use MISSING_VPRINTF rather than HAVE_VPRINTF, so the
5900 default is to use the portable (vprintf) version rather than the
5902 * xm-news.h (MISSING_VPRINTF): Add.
5904 * valprint.c (val_print): Demangle fancy vtbl printouts. Lint.
5906 Sat Sep 8 00:24:12 1990 John Gilmore (gnu at cygint)
5908 * Remove stuff that forces -Bstatic linking of gdb, and warnings
5909 about linking debugged programs -Bstatic in the sun?os4 config
5910 files in tconfig and xconfig subdirectories.
5912 * main.c (main): Remove unreached exit(0) now that we exit
5915 * Create TODO file for online bug list. There are too many
5916 "little" bugs to keep track of on paper.
5918 * Change Projects file to refer to bug-gdb@cygnus.com
5919 rather than kingdon@ai.
5921 Fri Sep 7 23:35:15 1990 John Gilmore (gnu at cygint)
5923 * Makefile.dist (VERSION): 3.91.4 now.
5925 * symtab.c (init_misc_bunches): Rename from init_misc_functions.
5926 (condense_misc_bunches): Add sanity check that misc_count is
5927 the same as the number of symbols in the bunch.
5929 * coffread.c: rename init_misc_bunches. Pass an argument
5930 to condense_misc_bunches (a zero).
5932 * dbxread.c (partial_symbol_file_read): Call init_misc_bunches
5933 every time we are called; don't rely on our caller to do it.
5934 (add_file): Remove call to init_misc_bunches.
5936 * mipsread.c: Only warn, don't error, if unknown symbol types.
5937 This keeps an old gdb from falling on its face if it sees newly
5938 extended symbol info. Rename init_misc_bunches.
5940 Fri Sep 7 22:58:15 1990 John Gilmore (gnu at cygint)
5942 * Merge in changes from Per Bothner for DECstations and other
5943 MIPS stuff. The rest is Bothner speaking:
5945 The next message is a merger of Alessando Forin's mips port with
5946 mine. I've tried to use my good if biased judgment to get
5947 the best of both. It *does* need testing.
5949 Some of the changes are general, *not* mips-specific.
5952 Didn't believe in little-endian bit order.
5953 There are still inconsistencies about whether flags
5954 like BITS_BIG_ENDIAN are integer (#if ...) or
5955 boolean (#ifdef ...). I tried to paper over them.
5957 dbxread.c,coffread.c,mipsread.c,symtab.c,symtab.h:
5958 Moved some misc_function code that was common to
5959 {dbx,coff,mips}read.c to symtab.c.
5960 In the process, I think I cleaned things up a bit.
5961 At the same time, moved obsavestring and obconcat to symtab.c.
5964 Removed obsolete condense_addl_misc_bunches (use
5965 condense_misc_bunches(1) instead).
5968 Needed to include <sys/dir>, at least on DECstations.
5970 valops.c, mips-tdep.c, tm-mips.h:
5971 Added PUSH_ARGUMENTS macro to support funny argument-pushing
5972 conventions (when STACK_ALIGN is insufficient).
5973 Needed on mips, where doubles need 8-byte alignment,
5974 but ints only need 4.
5977 Removed cruft that was not being used.
5978 Merged in many fixes (most from Frank Yellin, fy@lucid.com).
5981 Print $ before register-names (I think that makes things a little
5983 Never print two instructions, even if one delays.
5984 Removed hex-disassemble set_cmd. (This is not mips-specific,
5985 so I think the argument is whether it is generally worthwhile or not.
5986 I'm inclined to think not, given how easy it is to
5987 convert between radixes in gdb.)
5990 This is basically Alessando's code.
5991 It doesn't use obstacks; I changed it to use obstacks
5992 in a few minor places where using malloc causes a
5993 memory leak. (Probably, more places could/should be changed.)
5994 I added record_misc_function where it was missing.
5995 In symbol_file_command and add_file_command, I tried
5996 to make the code consistent with more recent versions.
5997 Minor sylistic changes in parse_procedure.
5998 Make a .gdbinfo. psuedo-symbol point back to the real
5999 procedure symbol (using the isym field).
6002 This is basically from my port, but with a lot of details
6003 and a number of routines merged in from Alessando's version.
6004 I basically used my code "raw" backtrace (use heuristics
6005 from the actual code, rather than symbol table info) - though
6006 the idea is Alessandro's. I feel my code is a little cleaner
6007 here, particularly in being a little more flexible, such as being
6008 able to handle gcc-produced code (which it now can).
6009 It also doesn't do frame caching (which is not useful
6010 more recent gdb versions).
6011 I also used my code for push_/pop_dummy, more or less.
6012 I tried to incorporate AF's code for testing sigtramp
6013 while backtracing; I probably got it wrong.
6014 Added mips_print_register, which tries to scrunch as much
6015 information as possible on a screen...
6016 Removed the skip-prologue set_cmd. As with hex-disassemble (see
6017 under mips-pinsn.c), I don't see anything mips-specific here,
6018 and I don't see it being all that useful anyway.
6021 Added a $fp psuedo-reg distinct from $fp (nice for gcc).
6022 Use more register names (rather than hard-cases numbers).
6024 Thu Sep 6 18:33:15 1990 John Gilmore (gnu at cygint)
6026 * Hack up 3.90.11 changes:
6028 * Makefile.dist (depend): parameterize $(GCC).
6029 Add solib.c and solib.o.
6030 (readline): Fix vpath for both absolute or relative SRCDIR.
6032 * blockframe.c: Fix from Schaefer@asc.slb.com for shared libs.
6033 Also, let the part I didn't understand at least compile so
6034 I can test the rest. FIXME.
6036 * dbxread.c: Fix thinko using strcmp.
6037 (init_psymbol_list): declare static.
6038 (partial_symbol_file_open): Comment cleanups better, avoid
6039 cleaning up the string table since the caller will do that.
6040 Move the stat for mod time into symbol_file_command, temporarily.
6041 (There should be a mod time for each symbol file, eventually,
6042 to control its rereading. FIXME.)
6044 * infptrace.c (PT_WRITE_D): use same value as PT_WRITE_I for
6045 SunOS, which gives error for shared libs otherwise. (From
6046 Schaefer, probably FIXME needs work for portability.)
6048 * solib.c: Move #include "param.h" to work.
6049 Lowercase all the Uppercase Letters In the Messages.
6050 (find_solib): Clean up inferior_so_name for debug printouts.
6051 Allow no argument, to mean all shared libraries.
6053 * symmisc.c: include param.h to get CLEAR_SOLIB.
6055 Wed Sep 5 18:00:08 1990 John Gilmore (gnu at cygint)
6057 * Merge in Kingdon's changes from FSF: the diffs from 3.90.9
6058 to 3.90.11. ChangeLog entries below are from this.
6060 Wed Jun 13 09:17:39 1990 Jim Kingdon (kingdon at mole.ai.mit.edu)
6064 * Makefile.dist (HFILES): Add tm-sunos.h.
6066 Tue Jun 12 16:15:26 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
6070 * Makefile.dist (gdb.tar.Z): Change linking of config so it works.
6072 Thu Jun 7 16:22:27 EDT 1990 Jay Fenlason (hack@ai.mit.edu)
6074 * sparc-opcode.h Added single-operand version of rett.
6076 Mon Jun 4 18:12:31 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
6078 * m-sparc.h (REG_STRUCT_HAS_ADDR, STRUCT_ARG_SYM_GARBAGE):
6079 Put parens around gcc_p in expansion.
6081 Thu May 24 15:44:51 1990 Jim Kingdon (kingdon at mole.ai.mit.edu)
6083 * utils.c (lines_to_list): Return 10 if lines_per_page == 0.
6085 Wed May 23 16:36:04 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
6087 * Changes for Sun shared libraries:
6088 blockframe.c (find_pc_partial_function): If a non-text symbol
6089 is found, set *address = pc - FUNCTION_START_OFFSET.
6090 breakpoint.c (insert_breakpoints) [DISABLE_UNSETTABLE_BREAK]:
6091 Disable breakpoints instead of giving an error.
6092 source.c (select_source_symtab): Initialize cs_pst.
6093 symmisc.c: Call CLEAR_SOLIB if defined.
6094 symtab.h: Make text{low,high} CORE_ADDR not int.
6095 (psymtab): New field addr.
6097 dbxread.c: Move DECLARE_FILE_HEADERS outside functions.
6098 (record_misc_function): Give correct type for N_DATA symbols.
6099 (condense_misc_bunches): do "misc_function_count = j" regardless
6101 Take code which is shared between symbol_file_command and
6102 add_file_command and put it into partial_symbol_file_{open,read}.
6103 Split add_file_command into add_file_command and add_file.
6104 Make psymtab_to_symtab read in the string table if the file
6106 Two new parameters to read_dbx_symtab and start_psymtab.
6107 tm-sunos.h: New file.
6109 Tue May 22 17:43:03 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
6111 * infcmd.c: Change cont_command to continue_command and "cont"
6114 Mon May 21 14:41:41 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
6116 * breakpoint.c (enable_breakpoint): Get value of watchpoint.
6118 * defs.h [sparc]: Use <alloca.h> regardless of __GNUC__.
6120 * values.c (USE_STRUCT_CONVENTION): Check for structures of
6121 size 1,2,4,8 rather than size < 8.
6123 * dbxread.c (dbx_lookup_type): Do f->length *= 2 as many times
6124 as necessary, not just once.
6126 * sparc-opcode.h: Add a bunch of new opcodes which Sun as supports.
6128 Thu May 17 15:04:09 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
6130 * {t,x}m-sun386.h, sun386-xdep.c, {x,t}config/sun386
6132 * tm-news.h: Add CALL_DUMMY_*.
6134 * tm-68k.h: Remove duplicate comment at FRAME_FIND_SAVED_REGS.
6136 * config.gdb: In list_host, list_target, use ${i}, not $i.
6138 Tue May 15 21:27:12 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
6140 * source.c (find_source_lines) [BROKEN_LARGE_ALLOCA]: Use xmalloc.
6142 * sparc-opcode.h: Change all store floating-point state register
6143 instructions to have the right match & lose fields.
6145 Sat May 5 12:39:18 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
6147 * Makefile.dist: Move -I${srcdir} to GLOBAL_CFLAGS and pass
6149 config.gdb: If srcdir != ., create readline directory and
6150 copy a makefile into it.
6152 * wait.h, infrun.c: Change WRETCODE to WEXITSTATUS for
6153 consistency with POSIX.
6155 * breakpoint.c (bpstat_stop_status): Disable watchpoint
6156 when we exit its exp_valid_block.
6158 Tue Sep 4 11:46:46 1990 John Gilmore (gnu at cygint)
6160 * Makefile.dist: Bump version to 3.91.3.
6162 * Clean up handling of breakpoint commands (somewhat).
6163 Prompted by Tiemann bug report "cont 10" doesn't work any more.
6165 inferior.h: Add breakpoint_proceeded to inferior status struct
6166 and globals; save it and restore it.
6167 (clear_breakpoint_commands): Cleanup, remove old #define.
6169 infrun.c (clear_proceed_status): Set breakpoint_proceeded.
6170 (save_inferior_status, restore_inferior_status): handle it also.
6171 (proceed): Remove earlier code that set breakpoint_proceeded.
6172 It is now set only in clear_proceed_status.
6173 (clear_proceed_status): Cleanup, use bpstat_clear rather
6174 than clear_breakpoint_commands. No callers need the stop_bpstat
6175 between clear_proceed_status and proceed.
6177 infcmd.c: Add breakpoint_proceeded definition and comment.
6178 (cont_command, jump_command, signal_command): Move call to
6179 clear_proceed_status right next to call to proceed.
6181 breakpoint.c (bpstat_do_actions): Avoid clobbering our
6182 caller's argument while running down the chain of breakpoints.
6183 Use new variable "breakpoint_proceeded" to determine when
6184 a command that it executes moves the inferior past the
6186 (bpstat_clear): Handle NULL argument.
6187 (bpstat_clear_actions): Avoid useless call to
6188 breakpoint_auto_delete.
6189 (delete_breakpoint): Clean up bpstat's that are pointing to
6190 the deleted breakpoint from the stop_bpstat chain.
6191 (breakpoint_auto_delete): Simplify.
6193 * Clean up handling of EOF, error on stdin, etc. This was
6194 prompted by a network problem that caused gdb to go into an
6195 infinite loop filling up its malloc'd memory.
6197 main.c (return_to_top_level): Cleanup: call bpstat_clear_actions,
6198 not clear_breakpoints_commands, which is now gone.
6199 (main): If command_loop returns (e.g. from EOF on stdin), do
6200 a quit_command (looping back to command_loop if quit_command
6201 doesn't really quit).
6202 (command_loop): check result from command_line_input and
6203 exit if it returns NULL, rather than passing the NULL to
6205 (gdb_readline): Free malloc'd result space before returning
6208 * utils.c (query): Handle C-d to mean "yes", just as if the
6209 input was not a terminal. Also avoid infinite loop if EOF
6210 occurs in mid-input-line before newline. This allows
6211 query to be used at EOF on stdin with reasonable results.
6213 * infrun.c (proceed): Set breakpoint_proceeded.
6215 * values.c (value_as_long): Avoid infinite recursion for enums.
6216 (_initialize_values): Fix typo in help msg (kingdon).
6218 * Makefile.dist (RL_LIB): Use RL_LIB_DEP for dependencies,
6219 RL_LIB for linking. This allows -lreadline for linking
6220 and nothing for dependencies, once readline is a real library.
6222 * config.gdb: Jim Kingdon: give useful error message if the
6223 host or target type is not recognized.
6225 * defs.h (alloca): SPARC <alloca.h> does not declare alloca,
6226 it just defines it. Dumb, but deal with it.
6228 * Jim Kingdon suggests:
6229 in xconfig/sun3os4, CFLAGS should be XM_CFLAGS.
6231 Wed Aug 29 18:03:27 1990 John Gilmore (gnu at cygint)
6233 * Makefile.dist (VERSION): Bump version # to 3.91.2.
6235 * Clean up Bothner's changes.
6237 * blockframe.c (clear_pc_function_cache): New function.
6238 * blockframe.c: remake cache_pc_function_* static.
6239 * dbxread.c (symbol_file_command): remove references to
6240 cache_pc_function_* variables.
6241 * dbxread.c (read_struct_type): Use VOFFSET_STATIC.
6242 * printcmd.c: Avoid kludging a global variable (addressprint)
6243 to avoid printing the address of a string twice. Instead,
6244 pass the format letter 's' down low enough that it can be seen
6245 to avoid this problem.
6246 (print_formatted): Pass format arg to value_print.
6247 (restore_addressprint): Remove function.
6248 (do_examine): Avoid hacking addressprint, cleanups and such.
6249 (print_frame_args): Add a comment to a Bothner change.
6250 * symtab.h: define VOFFSET_STATIC and use it instead of "-1".
6251 * symmisc.c (free_all_symtabs): Call clear_pc_function_cache
6252 to wipe out the values cached in blockframe.c.
6253 * symtab.c (find_method): Add comment saying how big you must
6254 allocate to be "big enough". Per being terse again.
6255 * valprint.c (val_print): Handle format letter "s" to print
6256 strings without addresses. Add comment to vtbl printing code
6257 which casts with wild abandon. Rearrange reference-printing
6259 @0xaddr: value (print w/addressprint)
6260 value (print w/~addressprint)
6261 @0xaddr (parameter lists w/addressprint)
6262 or nothing (parameter lists w/o addressprint)
6264 Tue Aug 28 10:47:18 1990 John Gilmore (gnu at cygint)
6266 * Merge more changes from Per Bothner:
6268 Gdb's handling of TYPE_CODE_REF was so counter-C++ (and otherwise
6269 annoying) that I tried to improve it. Here are my suggestions.
6271 These patches all attempt to handle TYPE_CODE_REF (as in C++) better.
6274 Do automatic de-reference when taking the address of a reference.
6276 Don't deref_ref when printing parameter lists.
6278 More attempts at treating refernences properly.
6280 In val_print, if deref_ref==0, don't print dangling " = ".
6282 Add COERCE_REF macro, which de-references an REF.
6284 * Merge changes from Per Bothner:
6286 * Fixed (Sony news)-specific configuration problems.
6287 * Fixed other problems with using vanilla pcc and libc (enum problems;
6288 assumption that vsprintf exists).
6289 * Some major speed-ups (finc_pc_partial_function now caches a match;
6290 parsing avoids duplicate symbol_lookup calls).
6291 * Changed handling of baseclasses (no longer use baseclasses field
6292 of struct type, use the first n_baseclasses fields instead).
6293 * Various minor changes/fixes, most C++-related.
6296 Cache the most previous match from find_pc_partial_function.
6297 (Save both low and high ends of matching function's pc range.)
6298 This speeds up the loop of infrun.c:wait_for_inferior quite
6299 a bit, and makes step/next commands much zippier.
6301 Added an enum->int cast (otherwise, some compilers barf).
6303 No longer set baseclass offset to 0, since multiple
6304 inheritance now mostly works.
6305 Added a number of casts, to shut up compiler warnings
6306 (after stabs where made enums, not ints).
6307 When discarding a symbol table (in symbol_file_command),
6308 must clear the cache introduced in blockframe.c.
6309 Don't convert $vtbl_ptr_type to vtbl any more.
6310 Get rid of TYPE_BASECLASEES and baseclass_vec (see also symtab.h).
6311 Mask off sign bit emitted by g++ for virtual table offset.
6312 Set voffset to -1 (not 1) for static member functions.
6314 Changed parsing/lexing of names to avoid doing symbol lookup twice
6315 (once when lexing to determine symbol class, once for real).
6316 Now only call symbol_lookup once. Fields of 'this' win especially big.
6318 Subpress printing addr twice in the case of 'x/s addr'.
6320 lookup_basetype_type is no longer used.
6321 Add find_methods as recursive helper function to decode_line_1.
6322 This allows multiple inheritance to work.
6323 Also, once one or more matches has been found, do not look in
6324 base-classes. (Baseclass methods would be overridden, anyway.)
6326 Removed baseclasses array in struct type.
6327 Instead of using baseclasses[i], use fields[i-1].
6328 Added virtual_field_bits[i] to indicate if the i'th baseclass is virtual.
6329 Changed sign convention of voffset (previous was inconsistent).
6331 Some macros (CALL_DUMMY and relatives) were missing. Put them back.
6333 Used to assume existence of vsprintf. Re-written to not need it
6334 if HAVE_VPRINTF is undefined.
6336 typecmp was too pessimistic. Made it less so.
6338 Don't print space after address.
6339 If vtable points to a misc symbol (with 0 offset), print it,
6340 since that indicates the actual class of the object.
6341 Changed ype_print_derivation_info to use new inheritance
6342 scheme (without baseclasses vector).
6344 In value_primitive_field, fixed some bugs left over from previous set of fixes.
6345 Also, changes needed because TYPE_BASECLASSES were removed.
6347 REGISTER_U_ADDR didn't work for PC. Rewrote to use an array.
6349 Tue Aug 21 20:08:54 1990 John Gilmore (gnu at cygint)
6352 If there is no path set, and the symbols don't indicate what directory
6353 a file was compiled in, look in the current directory. But either
6354 a path or a known compilation directory will prevent this.
6357 Three independent bug fixes:
6358 * Remove the #if 0 block that breaks some stuff.
6359 * SunOS 4.1 fixed the promoted-parameter-wrong-addr bug in Sun C;
6360 adapt gdb to either SunOS 4.0.* or 4.1.
6361 * MAX_OF_TYPE and MIN_OF_TYPE thinko. By tedg@sun, I think.
6364 Instantiate the class T when looking for methods in it. (Tiemann@sun)
6367 (type_print) Demangle the name being printed.
6368 (type_print_base) Handle botched demangling without coredump (tiemann).
6371 (check_stub_method): Document routine.
6372 (tiemann) fix bug for no-arg functions
6373 Avoid clobbering beyond end of malloc'd storage.
6374 Terminate the argument list properly.
6376 Sat Aug 18 01:29:59 1990 Per Bothner (bothner@cs.wisc.edu)
6378 * Changes merged by John Gilmore:
6381 In breakpoint_1, use new print_address_symbolic instead
6382 of find_pc_partial_function. (This forces use of assembler-level
6383 addresses, and avoids misleading non-mangled source-level names.)
6385 Generalize ansi argument such that -1 means skip arglist totally.
6386 Removed global variable print_ansi_qualifiers (which made
6387 code non-reentrant), in favor of extra explicit arguments
6388 to internal routines.
6390 Add new helper function print_address_symbolic.
6391 Use find_pc_misc_function instead of find_pc_partial_function
6392 (since we want assembler-level symbols here).
6394 Print unknown function as just "f (...)", not "f (...) (...)".
6395 Use new fputs_demangled explicitly.
6397 Fixed a typing violation (problem: value.h cannot be imported
6398 without renaming many variable in this file).
6399 lookup_symbol: If no matching misc_func, look for a C++-mangled name.
6400 decode_line_1: Moved forward some never-reached code.
6401 Made decode_line_2 skip function prologues correctly.
6403 fputs_filtered should not demangle by default.
6404 Add new fputs_demangled to demangle on demand..
6406 Change value_struct_elt to use value_primitive_field (using recursive
6407 utility function search_struct_field). This allows foo.bar to work
6408 for multiple inheritance (so far only for data fields).
6409 Change check_field in the same way (recursive helper function
6410 to support multiple inheritance).
6411 (Note: there are more of these problems that I haven't fixed.
6412 Any code that says TYPE_BASECLASS (t, 1) is probably wrong.)
6413 value_of_this: 'this' symbol name is now just "this", note "$this".
6415 Don't print static members.
6416 Avoid printing "members of <type>" if there are none.
6417 Simplified type_print_derivation_info by merging duplicate code.
6418 Remove useless blank lines in type_print_base (ptype command).
6420 Added declaration of new routine value_primitive_field.
6422 Added value_primitive_field which is generalized version of
6423 value_field that can handle multiple inheritance (non-zero offsets etc).
6424 Re-implemented value_field to call value_primitive_field.
6426 Fri Aug 17 23:33:44 1990 John Gilmore (gnu at cygint)
6428 * infcmd.c -- insert else to avoid 'delete env' coredump when you
6429 delete the whole environment. Karl Berry reported the bug.
6430 * source.c - fix openp to avoid //'s in filenames, which
6431 trigger an Emacs bug causing it to not be able to find files
6432 when running gdb in a window.
6433 * dbxread.c - zap the #if 0 that botches the add-file code.
6434 It seems to work a lot better without all the code commented out.

6451 to remove signle step breakpoint instructions.
6452 * main.c added "-epoch" flag and "int epoch_interface" to main.c

6457 format controls easier
6458 * wait.h added a couple of undef's because we were getting
6459 complaints about WSTOPSIG and WTERMSIG begin redefined.
