3 Fix bugs in C++ debugging.
5 * symtab.h: target_type is not used in record types.
6 Eliminate TYPE_MAIN_VARIANT and TYPE_NEXT_VARIANT. Eliminate
7 lookup_method_type. Add TYPE_TYPE_SPECIFIC macro.
9 * symtab.c (lookup_member_type): Don't chain them up, just
10 allocate one in symbol_obstack when we need one.
11 (allocate_stub_method): Build stub in symbol_obstack.
12 (check_stub_method): Move here from values.c. Don't deallocate
14 (lookup_method_type): Gone now.
16 * buildsym.c: Handle g++ v1 stabs a little bit better.
17 Change some C++ parsing error()s to complain()ts.
18 * buildsym.c, findvar.c, printcmd.c, symtab.c: Make unions and
19 structs have the same representation and work the same as far as
21 * buildsym.c, symtab.c, values.c: Remove all references to
22 TYPE_MAIN_VARIANT and TYPE_NEXT_VARIANT.
24 * valops.c: Improve comments and indentation. Only call
25 check_stub_method when the stub flag is on.
26 * valprint.c: Fix or mark minor bugs and unportabilities.
28 * coffread.c (anonymous unions): Allocate a cplus structure.
30 * mipsread.c: Eliminate "template" types. Build new, real
31 types whenever we need them. Allocate cplus structures as needed.
32 Bulletproof the type parsing a bit more. Mark storage leaks.
33 (parse_type): Copy TYPE_TYPE_SPECIFIC when copying a real type
34 on top of a partial type.
36 Fri Nov 22 16:39:57 1991 John Gilmore (gnu at cygnus.com)
38 * inflow.c (terminal_inferior): Check the results of ioctl's, and
39 print a message if any of them fail.
40 (terminal_ours_1): Store result of ioctl's for debugging, but
41 don't print (the terminal isn't ours...).
43 * tm-tahoe.h (FRAME_ARGS_ADDRESS): No need to offset from frame
46 * m2-exp.y (MAX, MIN): Rename to MAX_FUNC, MIN_FUNC to avoid
47 conflicts with system header files.
49 Fri Nov 22 08:27:40 1991 John Gilmore (gnu at cygnus.com)
51 * Roll VERSION to 4.2.95.
53 * buildsym.c, coredep.c, mem-break.c, xcoffread.c: Put <stdio.h>
55 * config/mh-i386sco: Override compiler to gcc, print warning.
56 * configure.in: Handle i386-none-aout rather than i386-aout-none.
57 * infptrace.c, language.h, utils.c: Lint.
58 * m2-exp.y: #undef MAX and MIN in case system includes set them.
59 * xm-tahoe.h: Set HOST_BYTE_ORDER. Include system versions of
60 {BIG,LITTLE}_ENDIAN and the INT_MAX family first, to avoid
61 redefinition warnings.
62 * defs.h: Reorder things so that the xm-file gets first crack
63 at #define's, followed by defs.h and then the tm-file.
64 * Makefile.in: Remove spaces after 'ignore exit code' - flags.
65 Late-model BSD 'make's don't cope with them.
67 Thu Nov 21 23:48:56 1991 John Gilmore (gnu at cygnus.com)
69 * Makefile.in: Roll new files into various lists.
71 Thu Nov 21 18:26:11 1991 Fred Fish (fnf at cygnus.com)
73 * dwarfread.c (struct_type): Must initialize the c++ specific
74 portion of union types as well as struct types, since gdb attempts
75 to reference the c++ specific info for both types.
77 Thu Nov 21 10:23:52 1991 John Gilmore (gnu at cygnus.com)
79 * Makefile.in: Roll VERSION to 4.2.90.

101 Wed Nov 20 18:35:56 1991 John Gilmore (gnu at cygnus.com)
103 * Remove gdb/hp-include. Support for HP a.out oddities should be
104 in BFD, not in GDB. Move gdb/hp-include/a.out.h to include/a.out.hp.h.
106 * infptrace.c, tm-sun386.h: Cashier <a.out.gnu.h>, remove refs.
108 * configure.in, xconfig, tconfig, Makefile.in, doc/gdbint.texinfo:
109 Makefile fragments for various hosts and targets now come from
110 gdb/config/mh-* and gdb/config/mt-*. This is for consistency with
113 * rs6000-pinsn.c, rs6k-opcode.h: Clean up.
114 * rs6k-opcode.def: Delete.
116 Wed Nov 20 05:04:40 1991 Fred Fish (fnf at cygnus.com)
118 * dwarfread.c: Recognize obsolete form of AT_element_list
119 attribute still used by at least one AT&T compiler, and possibly
122 Tue Nov 19 07:53:55 1991 Fred Fish (fnf at cygnus.com)
124 * dwarfread.c (enum_type, struct_type): Ignore names invented by
125 helpful compilers for anonymous structs, unions, and enums.
127 * c-exp.y, m2-exp.y: Add defines for yymaxdepth, yy_yys, and
128 yy_yyv, so multiple parsers produced by SVR4 versions of yacc
129 can coexist in the same executable without collision.
131 * symtab.h: Add declaration for lookup_template_type() to kill
132 compiler warnings about conversions from int to pointer.
134 Mon Nov 18 17:45:18 1991 Fred Fish (fnf at cygnus.com)
136 * procfs.c: Move inclusion of defs.h to before param.h, as in
137 all the other source files that include both. This is required
138 to supply some typedefs that are used in files included by param.h.
140 * m68k-tdep.c (m68k_skip_prologue): Add generic m68k support for
141 skipping function prologues, ala the other cpu families (i386,
142 mips, m88k, etc). Add the ability to skip movm and fmovm
143 instructions in the prologues. Still needs support for profile
144 (-p compiled) prologue sequences (FIXME).
146 * tm-68k.h: Change SKIP_PROLOGUE macro to use the new generic
147 m68k prologue skipping function by default.
149 * tm-altos.h, tm-isi.h: Continue to use the old definition of
152 Mon Nov 18 15:12:45 1991 John Gilmore (gnu at cygnus.com)
154 * Makefile.in: Remove tdesc stuff, and extra blanks before colons.
155 * blockframe.c: Remove tdesc-related code. Default
157 * infrun.c: Remove tdesc-related code.
158 * m88k-tdep.c (frame_chain_combine, init_frame_pc): Remove copies
159 of defaultable things.
160 * tm-m88k.h: New file, common to all Moto 88k target configs.
161 Derived from tm-delta88.h.
162 * tm-delta88.h: Use it.
163 * xm-m88k.h: Common file for 88K hosts. Remove obsolete stuff.
164 * xm-delta88.h: Use it.
165 * tm-*.h: Remove FRAME_CHAIN_COMBINE macros, since all are
167 * coffread.c: Remove tdesc stuff.
168 * tconfig/delta88, tconfig/m88k: Remove tdesc stuff.
169 * xconfig/m88k: Rename tm-88k.h to tm-m88k.h.
171 Mon Nov 18 13:51:37 1991 Per Bothner (bothner at cygnus.com)
173 * source.c (open_source_file): If openp fails, try again
174 using just the base (non-directory) part of the filename.
175 This solves various annoying problems, such as when the
176 source was compiled with an absolute pathname - and the
177 source files have moved. Or if the source was compiled
178 using a relative pathname, it can be more convenient
179 to just specific the source directory to the dir command.
181 Mon Nov 18 00:04:41 1991 Fred Fish (fnf at cygnus.com)
183 * cplus-dem.c (munge_function_name): Add missing third arg to
184 instance of call to do_type().
186 * dwarfread.c: Changes to match new dwarf.h. Remove
187 AT_deriv_list, AT_loclist, AT_incomplete, AT_const_data,
190 Sun Nov 17 16:20:53 1991 Michael Tiemann (tiemann at rtl.cygnus.com)
192 * symtab.h (struct type): Moved C++-specific fields into new type
193 `struct cplus_struct_type'. Now takes 10% less memory. Many
195 * symtab.c (init_type): Don't set fields belonging to
196 TYPE_CPLUS_SPECIFIC unless TYPE is TYPE_CODE_STRUCT.
197 * buildsym.c (read_type): Allocate TYPE_CPLUS_SPECIFIC for
199 (read_struct_type): Ditto. Also, add comments about how we can
200 deduce TYPE_VPTR_FIELDNO from inheritance info and fieldname info.
201 * coffread.c (decode_base_type): Allocate TYPE_CPLUS_SPECIFIC for
203 (read_struct_type): Ditto.
204 * dwarfread.c (struct_type): Ditto.
206 * symtab.c (read_range_type): Don't set TYPE_MAIN_VARIANT.

217 * mipsread.c (parse_partial_symbols): patch to keep DEC C
218 compiler from making gdb bomb out. Thanks to Ed Santiago!
220 Thu Nov 14 19:27:30 1991 Fred Fish (fnf at cygnus.com)
222 * symfile.c: Add function compact_misc_function_vector() to
223 remove duplicate misc function vector entries. See comments
224 in source for why this is necessary/desirable.
226 * dwarfread.c: Add misc function type parameter to internal
227 record_misc_function(). Remove calls to init_misc_bunches()
228 and condense_misc_bunches(), these are now done in elfread.c.
230 * elfread.c: Add support for reading bfd canonical symbol tables
231 and generating misc function vector entries for global and
232 absolute symbols. Do calls to init_misc_bunches() and
233 condense_misc_bunches() where they will enclose all calls to
234 record_misc_function(), including those in dwarfread.c.
236 Thu Nov 14 17:02:11 1991 Roland H. Pesch (pesch at cygnus.com)
238 * doc/Makefile.in: new targets gdb.me, gdb.ms, gdb.mm
239 (roffable documentation).
240 * doc/gdb.texinfo: embedded hints (as comments) for better
241 texi2roff conversion.
243 Thu Nov 14 13:18:25 1991 John Gilmore (gnu at cygnus.com)

257 Motorola 88000 port without tears, I mean without tdescs.
259 * m88k-tdep.c: Blow away all tdesc stuff.
260 Provide functions for all the frame-related macros in
261 tm-delta88.h. Adopt i960-style EXTRA_FRAME_INFO.
262 (examine_prologue, frame_find_saved_regs, skip_prologue): borrow
263 from i960-tdep.c and adapt to the function prologues on the 88k.
264 (read_next_frame_reg): Borrow from mips-tdep.c.
265 FIXME: frame_locals_address should go away.
267 * tm-delta88.h: Dump all the tdesc stuff.
268 Macros for all frame-related stuff call fns of same name.
269 Remove duplicated definitions. FP_REGNUM becomes same as
272 * xm-88k.h: Eliminate lots of library dependencies, now handled
273 in libiberty. Eliminate KDB nonsupport.
275 * doc/gdbint.texinfo: Add rudiments on frames. FIXME, add more.

303 Fixes to support C++ methods with functional parameters.
304 * c-exp.y (func_mod rule): Allow (and ignore) list of parameter
305 types in a function type.
306 * eval.c (parse_and_eval_type), value.h: New function,
307 parse_and_eval_type, is based on old code from check_stub_method.
308 But don't actually evaluate the cast, since that calls
309 value_cast(), whcih may fail. Just extract the type
310 from the parsed expression.
311 * values.c (check_stub_method): While looping through the
312 arguments, adjust depth *after* parameter has been handled.
313 Replace call and setup of parse_and_eval with new function
316 Tue Nov 12 09:40:07 1991 Fred Fish (fnf at cygnus.com)
318 * utils.c, rem-multi.shar: Remove fixed arg count version of

324 sun386-xdep.c, symm-xdep.c, umax-xdep.c, values.c, xcoffread.c:
325 Change all instances of use of fixed args concat() to variable
326 args concat() now located in libiberty.

334 * rs6000-pinsn.c, rs6000-tdep.c, rs6000-xdep.c, tm-rs6000.h,
335 xm-rs6000.h, rs6k-opcode.def, rs6k-opcode.h: New files.
336 * xcoffexec.c: New file for handling AIX shared libraries.
338 Mon Nov 11 19:14:31 1991 Fred Fish (fnf at cygnus.com)
340 * core.c: Minor rewording of message to user containing name of
341 (and possibly arguments to) the program that generated a core
344 * elfread.c: Remove the register_addr() stub now that it is no
347 * procfs.c: Move misplaced #endif for ATTACH_DETACH. Add new
348 fetch_core_registers() function for core file support.

352 * dwarfread.c (dwarf_psymtab_to_symtab): Remove leftover call
353 to do_cleanups() which resulted from a previous change.
355 * elfread.c: Re-enable compilation of register_addr() stub
356 whenever it is not supplied by coredep.c
358 Sat Nov 9 00:40:32 1991 John Gilmore (gnu at cygnus.com)
360 Add tracking of object files (that contain symbols) to gdb.
361 This includes a "struct objfile" that owns symtabs and psymtabs
362 that were read in from that binary file.
364 * symfile.h: Add struct objfile. Add pointer to the objfile
365 into the struct sym_fns.
366 Replace global `symfile' and `symfile_mtime' with
367 `symfile_objfile'. Add global object_files chain.
369 * symfile.c: Move param.h above symtab.h.
370 (sort_misc_function_vector): Add.
371 (syms_from_objfile): Was syms_from_bfd.
372 (symfile_open): Now returns objfile.
373 (allocate_objfile): New.
374 (free_objfile): New, replacing free_all_.*symtabs.
375 (symfile_init): Takes objfile arg, puts it in sym_fns result.

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

426 (struct symtab): Add objfile * and objfile_chain * of symtabs.
427 (struct partial_symtab): Add objfile * and objfile_chain * of
428 psymtabs. Remove symfile_name.
430 * symmisc.c: Lose free_all_symtabs, free_all_psymtabs.
431 (printsyms_command): Rename from print_symtabs. Add selective
432 listing if 2nd argument given. Print objfile info.
433 (printpsyms_command): Rename from print_partial_symtabs. Ditto all.
434 (printobjfiles_command): New; prints objfiles lists, and checks
435 for consistency of symtab, psymtab, and objfile lists.
437 * symfile.h, symfile.c, symtab.h: Lint
439 Fri Nov 8 23:38:48 1991 John Gilmore (gnu at cygnus.com)
441 * command.c: Include param.h.
442 * defs.h (warning_setup, warning): Declare.

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

1012 Fri Sep 20 16:10:52 1991 John Gilmore (gnu at cygnus.com)
1016 * Makefile.in (VERSION): Set to 4.1.
1017 * language.c (set_language_command): Print useful help message,
1018 and restore the language string after giving help.
1019 * valprint.c (typedef_print): Print typedef in C or M2.
1020 * symtab.c (list_symbols): Use it.
1021 * main.c (main): Avoid any output before (gdb) prompt when -q.
1022 * language.c (set_language_command): Handle errors by restoring
1023 the language string to its current state (fix from A. Beers).
1024 * doc/gdbint.texinfo: Roll in information from README. Rearrange
1025 "how to install" and "how to print the doc" stuff so it drops
1027 * configure.in: Rename rtpc CPU to romp to match config.sub.
1028 * README, WHATS.NEW, TODO: Update for gdb-4.1.
1030 Fri Sep 20 17:39:14 1991 Roland H. Pesch (pesch at cygnus.com)
1032 * doc/gdb.texinfo: Updates from ChangeLog. set/show write,
1033 autoloading shared libs, copyright etc on GDB startup, clean up $_
1034 and $__ index refs, set/show listsize and related updates to list
1035 cmd. New host/target configs.
1037 Fri Sep 20 15:46:00 1991 Roland H. Pesch (pesch at cygnus.com)
1039 * doc/Makefile: generate aux version-no file doc/gdbVN.m4
1040 from main Makefile.in version definition
1041 doc/gdb.texinfo: use version recorded in doc/gdbVN.m4 for current
1043 Makefile.in (setup-to-dist): generate doc/gdbVN.m4
1045 * doc/gdb.texinfo: merge new language-switching and lang-specific
1048 Fri Sep 20 15:00:57 1991 Per Bothner (bothner at cygnus.com)
1050 * mcheck.c: Add __ONEFILE kludge to allow compilation by non-ANSI
1051 compilers (which may lack stddef.h).
1053 Fri Sep 20 13:29:42 1991 John Gilmore (gnu at cygnus.com)
1055 * dbxread.c (read_dbx_symtab, process_one_symbol): N_FN and
1056 N_WARNING are the same except for the N_EXT bit, so just use their
1057 values alone, rather than OR-ing them with N_EXT.
1059 Fri Sep 20 12:27:55 1991 Stu Grossman (grossman at cygnus.com)
1061 * mipsread.c (parse_lines): Deal with negative extended line
1064 * c-exp.y, m2-exp.y: #define yyerrflag and yynerrs to avoid
1065 global symbol conflicts.
1067 Fri Sep 20 02:28:15 1991 John Gilmore (gnu at cygnus.com)
1069 * .gdbinit: Move 'set complaints' to top, so it runs even in
1070 case we aren't debugging GDB.
1071 * language.c (_initialize_language): Fix type check and range
1072 check documentation strings.
1073 * utils.c (!HAVE_VPRINTF): Define vfprintf as a function, so
1074 language.c can use it. (Though language.c should really not be
1075 handling warnings/errors the way it does, FIXME.)
1076 * symtab.c (lookup_primitive_type): const lint.
1078 Bugfix from Peter Schauer:
1079 * source.c (lines_to_list): Make signed, to avoid comparison
1080 going unsigned and complaining that -3 is too high for 21 lines.
1081 * stack.c (lines_to_list): Ditto.
1083 Thu Sep 19 23:33:41 1991 John Gilmore (gnu at cygnus.com)
1085 * Makefile.in (HFILES): Add minimon.h.
1086 (VERSION): Roll version number to 4.0.95.
1087 (gdb.tar.Z, make-proto-gdb.dir, setup-to-dist, gdb-XXX.tar.Z):
1088 New rules for building distributions. Normal distribution
1089 is built by doing `make -f Makefile.in gdb.tar.Z' in the directory
1090 one level up from here; it calls make-proto-gdb.dir to build a
1091 directory `proto-gdb' which is an image of the release. The old
1092 `gdb.tar.Z' rule still works too.
1093 * config.sub, configure: Roll in latest from ..
1095 Thu Sep 19 17:41:24 1991 Roland H. Pesch (pesch at cygnus.com)
1097 * doc/gdbint.texinfo: Reorder contents; reorganize new-host,
1098 new-target, and new-config chapters; fix minor typos; come closer
1099 to usual GNU markup conventions for @file @samp @code @var.
1101 Thu Sep 19 17:04:12 1991 Per Bothner (bothner at cygnus.com)
1103 Patches from Peter Schauer <pes@regent.e-technik.tu-muenchen.de>:
1104 * mipsread.c (parse_partial_symbols): Enter the name of all
1105 structs/unions... into the psymtab so we can access them if the
1106 symtab is not read in.
1107 * mips-tdep.c: Remove some unneeded #includes.
1108 * xconfig/dec3100: Add HAVE_STRSTR.
1110 Thu Sep 19 15:14:23 1991 John Gilmore (gnu at cygnus.com)
1112 * Makefile.in: Circumvent Sun Make bug on *-exp.tab.o.
1113 * c-exp.y, m2-exp.y: Lint.
1114 * m2-exp.y: Avoid using yytname[] which is a Bison-ism.
1115 * valprint.c (val_print_fields): Check for stub type.
1116 * mipsread.c (_initialize_mipsread): Avoid using
1117 builtin_type_void at initialize time.
1118 (mipscoff_symfile_read): use it now.
1120 Wed Sep 18 15:55:51 1991 John Gilmore (gnu at cygnus.com)
1122 Merge multiple-language support, and partial Modula-2 support,
1123 from Andrew Beers <beers@cs.buffalo.edu>.
1125 * i387-tdep.c: New file, consolidates most 80387 support,

1145 (process_coff_symbol): #if 0'd for functions and params as above.
1146 (read_enum_type): Recognize Modula-2 BOOLEAN.
1147 * symtab.c (add_param_to_type): #if 0'd function to add a

1154 hex with local_hex_string for Modula-2 support.
1156 * breakpoint.c (breakpoint_cond_eval): Use new value_true to test

1183 TYPE_CODE_BOOL and TYPE_CODE_CHAR.
1185 * expression.h (enum exp_opcode): Add Modula-2 specific opcodes.
1186 * expprint.c: Look up expression opcodes in language-specific

1219 Tue Sep 17 08:37:41 1991 John Gilmore (gnu at cygint.cygnus.com)
1221 Add Andrew Beers' changes for Modula-2 support. His ChangeLog
1222 entries are enclosed herein. Not all of these changes
1223 have been merged into the master GDB sources -- check the
1224 ChangeLog above here for the merge log.
1226 Mon Jun 3 17:05:45 EDT 1991
1228 m2-exp.y Created. Tested outside of GDB for a few days. Proper
1229 operators were added, C specific operators and tokens
1230 removed. yylex() revamped to some extent. Still things
1231 missing from the grammar, such as sets.
1232 Tested for two weeks in GDB v3.5.
1234 Tue Jun 11 17:23:48 EDT 1991
1236 m2-exp.y Added boolean constants TRUE and FALSE to the grammar
1237 so they are built-in. Sort of a hack.
1239 Fri Jun 14 12:53:51 EDT 1991
1241 m2-exp.y Added range checking for numeric constants. Any numeric
1242 constant is assumed to be of builtin type INTEGER unless:
1243 (1) it is octal or hexadecimal, in which case it is a
1244 CARDINAL; (2) it is too big to fit into an INTEGER, in
1245 which case it is a CARDINAL.
1246 eval.c Added simple range checking for +, -, and * on integers.
1247 Doesn't work very well for *, since 6 * 1,000,000,000 =
1248 1,705,032,704, which fails the simple test of result >=
1249 first_operand, no matter in what order the operands are.
1251 Tue Jun 18 14:11:30 EDT 1991
1253 Broke the parser into parts, one containing the C grammar and the other
1254 containing code to be shared by all of the grammars.
1256 The following files no longer exist:
1261 The following files were added:
1263 c-exp.y (The C grammar)
1264 m2-exp.y (The Modula-2 grammar)
1265 parser-code.c (Code that is shared by the above grammar)
1269 Makefile.dist Changed to reflect the above dependencies. NOTE: It is
1270 now necessary to use the Bison compiler compiler, since it
1271 will generate function/variable prefixes other than yy.
1273 Tue Jun 18 16:47:49 EDT 1991
1275 symtab.[ch] Added the external variable working_lang, than holds the
1276 value of the current working language.
1277 Added the ennumerated type language_mode, with the values
1278 language_auto and language_manual, the former meaning that
1279 GDB sets working_lang as needed, and the latter meaning
1280 that the value of working_lang is totally under user
1282 symtab.[ch] Added the Modula-2 pervasive types INTEGER, CARDINAL,
1283 REAL, BOOLEAN and CHAR. Also added the type codes
1284 TYPE_CODE_BOOL and TYPE_CODE_CHAR.
1285 utils.c Added set_language_command and show_language_command to
1286 implement the GDB support commands "set language" and
1288 expression.h A number of identifiers were added to the type exp_opcode
1289 to facilitate Modula-2 builtin functions, integer
1290 division, and array indexing.
1292 Wed Jun 19 13:25:58 EDT 1991
1294 language.h Added the macro STRICT_TYPE, which evaluates to non-zero
1295 if the language specified by working_lang requires the use
1296 of strict typing of expressions. Eventually, even this
1297 will be able to be changed by the user.
1298 Added the macro RANGE_CHECK, which evaluates to non-zero
1299 if the language specified by working_lang requires the
1300 checking of a value against the domain of its type.
1301 Eventually, even this will be able to be changed by the
1303 language.[ch] Predicates involving types (simple_type, ordered_type,
1304 same_type, integral_type, numeric_type, character_type,
1305 boolean_type, float_type) are added. These predicates are
1306 based on the current value of working_lang, and are handy
1309 Wed Jun 19 15:39:34 EDT 1991
1311 eval.c Added the function type_array_rank which computes the rank
1313 valarith.c Added the funtion value_bool, which when given a integer
1314 value.h value (ie. struct value *) as an argument, it returns a
1315 boolean value (ie. struct value *) true if that integer
1316 is non-zero, and a boolean value false otherwise.
1317 valprint.c Added cases for TYPE_CODE_BOOL, so Modula-2 BOOLEAN values
1318 will print out properly.
1320 Wed Jun 19 16:36:34 EDT 1991
1322 valops.c Added the function value_capitalize, which returns it
1323 value.h argument capitalized if its argument is a lowercase
1324 letter, or the argument unchanged if its argument is not a
1326 valarith.c Added the function range_check_p, which returns non-zero
1327 value.h if its value argument is between the integral bounds upper
1329 Added the function range_check_enum_p, which makes sure
1330 that its value argument is a valid member of the domain of
1332 Added the function range_check_range_p, which makes sure
1333 its value argument lies between the upper and lower bounds
1334 of its type argument, which must be a ranged type.
1335 Added the function check_array_index, which range and type
1336 checks an index of an array.
1337 Added the function value_multi_subscript, which computes
1338 array[idx1,idx2...idxN], given a value array and an array
1339 of values representing indicies.
1340 values.c Changed value_from_long to work with TYPE_CODE_CHAR and
1341 unpack_long to work with TYPE_CODE_BOOL and
1344 Wed Jun 19 18:04:08 EDT 1991
1346 symtab.c Stored pervasive types in a structure and make
1347 lookup_pervasive_type() a lookup function that was based
1348 on working_lang. If lookup_pervasive_type() returned
1349 non-zero, then that value was returned (a fix, since
1350 before it simply wouldn't return the pervasive type.)
1351 language.h Added the macro CAST_IS_CONVERSION, which evaluates to
1352 non-zero if the language specified by working_lang means
1353 "conversion" when it says "cast".
1354 valops.c Added the function value_real_cast(), which performs a
1355 value.h *cast*, not a *conversion*, which is what value_cast()
1356 does when it can. In particular,
1357 value_cast(<float_type>,4) = 4.0, while
1358 value_real_cast(<float_type>,4) = some mess.
1359 eval.c Modula-2 builtin functions implemented: ABS, CAP, CHR,
1360 parser-code.c FLOAT, HIGH, MAX, MIN, ODD, ORD, TRUNC, and VAL.
1361 expression.h Added macros MAX_OF_TYPE and MIN_OF_TYPE to work with MAX
1362 and MIN on integral types. *NOTE*: These are currently
1363 hardcoded to work only if there are 8 bits per storage
1365 eval.c Made logical functions call value_bool to return a
1366 properly typed boolean value, based on working_lang.
1368 Thu Jun 20 11:55:27 EDT 1991
1370 valprint.c Types now print out in a Modula-2 fashion. This works for
1371 the cases when the type is printed out step-by-step, that
1372 is, it doesn't work when the name of a structured type
1373 (which includes the keyword "struct", etc.) is simply
1375 FIXME: Perhaps this is bad. Parts of it seem to kludgey,
1376 since type specifications in C and Modula-2 are very
1377 different. The C printing of a type is very recursive,
1378 whereas in Modula-2 it is generally very simple. C has
1379 type prefixes and suffixes, which have no real analogue in
1380 Modula-2. Maybe type_print() should call a language
1381 specific type printer. This is also advantageous if we
1382 compile GDB to exclude some of the languages. We'll just
1383 leave those functions out.
1385 Thu Jun 20 16:57:10 EDT 1991
1387 dbxread.c When reading the complete symbol table in (via
1388 psymtab_to_symtab()), the number and types of function
1389 arguments are added to a function type. define_symbol()
1390 calls add_param_to_type() to accomplish this.
1391 Assumption: when we come across a function definition
1392 (N_FUN symbol with an 'f' or 'F' in the name), its
1393 arguments will appear before another function definition.
1394 When a function is found, a pointer to its type is placed
1395 in the global in_function_type. Changes that
1396 add_param_to_type() makes are to this global.
1397 valprint.c The type of a function now includes (for Modula-2) the
1398 types of its parameters.
1399 eval.c Type checking and a check for the proper number of
1400 arguments is now done for function calls. Not sure of the
1401 impact this has on C++ member function yet.
1403 Thu Jun 20 19:58:48 EDT 1991
1405 valprint.c Rewrote the type printer. Broke it into two language
1406 specific parts, adding the functions type_print_m2() and
1408 An unfortunate consequence is this: if you debugging a C
1409 program in Modula-2 mode (why?), info types does not work
1410 well with regular expressions, since the types are printed
1411 out in Modula-2 terminology, but stored in C terminology.
1412 language.[ch] Added the functions new_type_last(), type_keyword(), and
1413 type_sep() to aid in the printing of typedefs.
1414 symtab.c Made the printing of typedefs as language independent as
1415 possible through calls to new_type_last(), type_keyword(),
1418 Fri Jun 21 11:50:26 EDT 1991
1420 dbxread.c Check all incoming ennumerated types. If it looks like
1421 Modula-2's BOOLEAN type, then change the type_code of the
1422 type to TYPE_CODE_BOOL so we can process it as a boolean
1424 valprint.c Replaced some of the 0x%x with calls to sprintf and
1425 hexformat() in val_print().
1426 language.[ch] Added the function hex_to_string(), which converts its
1427 integral argument to a hexadecimal number (format is
1428 language based) and returns the result as a string.
1430 Mon Jun 24 12:25:07 EDT 1991
1432 valprint.c Some functions call type_print_1() directly, instead of
1433 value.h using type_print(), so they can specify where (column) to
1434 print things. Since type_print() takes care of language
1435 dependence, that needs to be called first. Added a
1436 parameter depth to type_print() (so it is now like
1437 type_print_1). Changed type_print to type_print_at, and
1438 made type_print a macro that passes a depth argument of
1440 symmisc.c Changed all calls to type_print_1 to calls to
1442 Makefile.dist Made it possible to build GDB for a specific set of
1443 depend languages. Do this by passing a definition for the macro
1444 LANGS to make. LANGS should be a string containing a
1445 space-separated list of language names (ie. LANGS="c m2").
1446 The default is to build all languages. Note that grammar
1447 files must follow the naming convention of <lang>-exp.y.
1448 gdb.lang This holds the current value of the LANGS macro. It is
1449 examined every time make is called, and is updated if
1451 eval.c Added #ifdef _LANG_<lang> to these files.
1452 expread.c Still need to add them to dbxread.c and coffread.c.
1460 Mon Jun 24 16:33:11 EDT 1991
1462 language.[ch] Added the functions hexformat_pre() and
1463 hex_to_string_pre(), which take a prefix argument to
1464 include in the format string. Thus, hexformat_pre("08") will
1465 return "0x08x" (if the working language is language_c).
1466 Made hexformat() and hex_to_string() calls to the above
1467 with "" as the prefix argument.
1469 am29k-pinsn.c, arm-pinsn.c, breakpoint.c, convex-tdep.c, exec.c, core.c,
1470 dbxread.c, i386-pinsn.c, i386-stub.c, i386-xdep.c, i960-pinsn.c,
1471 infcmd.c, inflow.c, m68k-pinsn.c, m68k-stub.c, m88k-pinsn.c,
1472 mips-pinsn.c, mips-tdep.c, ns32k-pinsn.c, printcmd.c, pyr-pinsn.c,
1473 pyr-tdep.c, pyr-xdep.c, remote-vx.c, remote.c, solib.c, source.c,
1474 stack.c, sun386-xdep.c, symfile.c, symm-xdep.c, symmisc.c, tahoe-pinsn.c,
1475 valprint.c, vax-pinsn.c
1477 Changed all occurences of 0x%[0-9]*l*x in printf format strings to
1478 calls to hexformat() and hex_to_string(). Format strings without
1479 the leading "0x" were ignored.
1481 depend Updated to take the above into account.
1484 Tue Jun 25 15:27:18 EDT 1991
1486 symtab.h Added the types range_mode_t, range_check_t, type_mode_t,
1487 and type_check_t to keep track of the current state of
1488 range and type checking.
1489 main.c Added the variables range_mode, range_check, type_mode,
1490 and type_check to record the current state of range and
1491 type checking. Added initialization code to main().
1492 language.h Changed the macros STRICT_TYPE and RANGE_CHECK to examine
1493 the above variables.
1496 Tue Jun 25 17:57:08 EDT 1991
1498 dbxread.c process_one_symbol() updates the variable (enum language)
1499 source_lang based on the extension of the filename
1500 contained in the N_SO sybmol that started this symtab.
1501 When end_symtab() is called, the value of source_lang is
1502 put into the language field.
1503 stack.c select_frame() sets working_lang (and possibly type_check
1504 and range_check) to the language field of the symtab
1505 associated with the frame that is selected if working_mode
1506 is language_auto. If working_mode is language_manual, a
1507 warning is printed and working_lang is not set.
1508 language.c Added the function set_type_range(), which sets the value of
1509 type_check and range_check (if their modes call for
1510 automatic setting) based on the current value of
1511 working_lang. A non-zero argument will cause the current
1512 settings to be output.
1515 Wed Jun 26 14:51:40 EDT 1991
1517 eval.c Added range checks on assignment.
1518 m2-exp.y Added the grammar for sets to the language. Currently,
1519 these do not do anything except print an error message.
1521 Wed Jun 26 17:01:04 EDT 1991
1523 m2-exp.y Added the ability for parse_number() to parse negative
1524 numbers. A global flag is set upon encountering a unary
1525 minus. This was done to make, for example, 1 parse as a
1526 CARDINAL, and not as an integer, per Wirth's examples in
1527 Programming in Modula-2 ed.4.
1528 valprint.c Added support for "set radix 2" by then setting
1529 output_format to 't'.
1530 eval.c Implemented range checking on subrange types. Added calls
1531 to range_check_range_p for BINOP_ASSIGN and BINOP_VAL.
1532 Implemented MIN and MAX for ennumerated types. The
1533 minimum value of an ennumerated type is defined by Wirth
1534 as the first identifier, and the maximum as the last.
1535 m2-exp.y Made octal numbers ending with "B" be characters and those
1536 ending with "C" be numbers, per Wirth's book. (p. 34)
1538 Thu Jun 27 14:11:52 EDT 1991
1540 stack.c select_frame() now only sets working_lang, it does not
1541 notify the user. If working_mode is language_manual, then
1542 a warning is issued once.
1543 main.c At the end of each call to execute_command(), working_lang
1544 is checked against the local static (enum language)
1545 current. If they differ and working_mode is
1546 language_auto, the new settings of language, type and
1547 range checking are printed out.
1548 stack.c Modified frame_info() to include the language of the
1549 current frame in the output of "info frame".
1550 language.[ch] Added the function language_str() which returns the name
1551 of the current language.
1553 Fri Jun 28 15:33:14 EDT 1991
1555 m2-exp.y Added the built-in procedures INC, INCL, DEC, and DECL to
1556 the language. INCL and DECL currently cause an error,
1557 since sets are not implemented yet. INC and DEC are
1558 implemented as PREINCREMENT/PREDECREMENT with one
1559 argument, and as ASSIGN_MODIFY with two arguments.
1560 eval.c Added type checking to the above cases.
1561 value.h Added not_lval_constant to the lval_type ennumerated type.
1562 not_lval_constant means that the value is a constant
1563 value; that is 3 or 'a' or TRUE, not as in a constant
1564 identifier. This is used to help coerce numbers such as 3
1565 to either signed or unsigned numbers.
1566 valops.c Added the function value_coerce_constants() which coerces
1567 constant integers as following: if one is a constant and
1568 the other is not, the constant's type is set to the type
1569 of the other argument. If both are constants and one is
1570 signed, the other is converted to a signed constant.
1572 Sat Jun 29 17:26:29 EDT 1991
1574 valarith.c Added a better range checker. It now checks range
1575 (successfully) on integral operations [+-] (signed and
1576 unsigned) for any C sized type. Still does not work well
1577 for multiplication.)
1578 int_in_size() returns an integer that is coerced to fit into
1579 specified number of bytes.
1581 Mon Jul 1 13:04:14 EDT 1991
1583 language.[ch] Added the function binop_result_type(), which returns the
1584 builtin (struct type *) type that would be the result of a
1585 binop on the two values V1 and V2.
1587 Wed Jul 3 19:22:53 EDT 1991
1589 source.c Extended source_info() to include the source language in
1590 the output from "info source".
1592 Fri Jul 5 13:48:52 EDT 1991
1594 utils.c Moved the support functions for the GDB set/show commands
1595 dealing with language into language.c.
1596 language.c Added the function language_info(), which displays info
1597 about the current working language, type and range check
1598 settings. Called via the GDB command "info language".
1599 Added an initialization routine _initialize_language(),
1600 that sets defaults for the language, type and range
1601 variables and sets up the new GDB commands.
1602 main.c Language setup moved to language.c.
1605 Mon Jul 8 10:10:22 EDT 1991
1607 valarith.c Debugged the range checker for arithmetic. Still does not
1608 work for multiplication very well.
1610 Mon Jul 8 12:40:37 EDT 1991
1612 language.[ch] Added the function value_true() which returns non-zero if
1613 its argument represents a boolean true value.
1614 breakpoint.c Changed breakpoint_cond_eval() to call value_true() to
1615 check the truth of an expression.
1617 Thu Jul 11 12:51:34 EDT 1991
1619 language.[ch] Added the predicate structured_type(), which returns
1620 non-zero if the argument is a structured type.
1621 Added the predicate pointer_type(), which returns non-zero
1622 if the argument is a pointer type.
1623 eval.c Added the ability to do addition and substraction on
1624 pointers and integers. This case simply bypasses the
1627 Thu Jul 11 14:41:42 EDT 1991
1630 Added the symbol N_DEFD (0x4a) which is a definition
1631 module dependency that is used by the GNU Modula-2
1632 compiler and the linker. It is not important to GDB,
1633 except that [dbx|coff|mips]read.c should ignore these
1636 Fri Jul 12 16:07:00 EDT 1991
1638 valprint.c Changed the TYPE_LENGTH(type) >= 0 to TYPE_LENGTH(type) >
1639 0 in val_print(). Also added statements to the else part
1640 to coerce type (argument to val_print) to a pointer type
1641 if it is an "array of unspecified length".
1642 valops.c Added the function value_m2_string(), which returns a
1643 (value) value which is a constant string, whose type is
1644 (ARRAY [0..n] OF CHAR). The length field of the type
1645 structure is set to zero, so it will be interpreted as an
1646 "array of unspecified length".
1647 stack.c Moved the language/frame mismatch check to
1648 main.c:execute_command().
1649 main.c The working language is recorded each time
1650 execute_command() is executed. If working lang has
1651 changed during its execution, then the new
1652 language/type/range info is printed out for the user. If
1653 the working language does not match the language of the
1654 frame, a warning is issued.
1656 Sat Jul 13 16:16:39 EDT 1991
1658 eval.c Moved all the type-checking stuff for operators to
1659 language.[ch] language.c. This is so we can keep language-specific
1660 stuff (like for what type operators are defined) in
1662 language.[ch] Added the function binop_type_check(), which checks to see
1663 if its two (value) arguments are type-compatible with its
1664 opcode argument. The opcode should represent an operation
1665 involving an operator. Also added the macro function
1666 unop_type_check, which calls binop_type_check with a
1667 NULL second argument.
1668 expprint.c Added Modula-2 operators to the op_print_tab, so info
1669 expression.h break works correctly. Also added "op_string", which
1670 returns the string corresponding to the (enum exp_opcode)
1671 opcode that is its argument.
1674 Sat Jul 13 18:26:18 EDT 1991
1676 coffread.c Added code to record the type of function arguments with
1677 each paricular function. Code is very similar to that
1679 dbxread.c Moved add_param_to_type() to symtab.c
1680 symtab.[ch] Added function add_param_to_type() from dbxread.c
1682 *** NOTE: The above additions have not been tested.
1684 Mon Jul 15 12:50:47 EDT 1991
1686 langauge.[ch] Added the functions type_error and range_error, which work
1687 like error() except if the type/range mode is set to
1688 *_mode_warn, then they do not do a return_to_top_level(),
1689 but merely print a warning.
1690 Also changed [set|show]_[type|range]_command() to support
1691 the new "warn" feature.
1693 Thu Jul 18 17:50:54 EDT 1991
1695 mipsread.c Added code to record the type of function arguments with
1696 each particular function. Code is very similar to that
1699 *** NOTE: The above additions have not been tested.
1701 Fri Jul 19 11:19:10 EDT 1991
1703 defs.h Added macros MAX_OF_SIZE, MIN_OF_SIZE, UMAX_OF_SIZE, and
1704 UMIN_OF_SIZE, which when given a size of a numeric type,
1705 return the maximum and minimum value it can hold. UMAX...
1706 and UMIN... return the result for unsigned types.
1707 symtab.h Added the macros MAX_OF_TYPE and MIN_OF_TYPE to operate on
1708 struct types. They call above macros.
1709 dbxread.c Renamed the MAX and MIN_OF_TYPE macros to ..._OF_CTYPE to
1710 avoid a name conlict with the above.
1711 c-exp.y Added range checking on numeric constants in
1712 parse_number() for completeness.
1713 valarith.c Made binop_user_defined_p() and unop_user_defined_p()
1714 return 0 if working_lang is not language_c.
1716 Thu Aug 8 14:17:22 EDT 1991
1720 breakpoint.c Documentation strings of some commands changed to
1721 eliminate the references to the C language where
1724 Tue Aug 13 15:48:03 EDT 1991
1726 m2-exp.y Added qualified identifiers to the grammar. The semantics
1727 are slightly different from those of the GDB operator ::
1729 m2-exp.y Added a rule to each grammar of the form: start ::= exp |
1730 type_exp, where type_exp is any valid type expression.
1732 eval.c Added the opcode OP_TYPE, and an error case in eval.c.
1733 printcmd.c Modified ptype_command() so it actually parses the input
1734 (necessary for type expressions with scope qualifiers).
1735 Added the function ptype_eval() which expects an
1736 expression composed of one OP_TYPE element.
1737 *.[ch] Replaced all occurences of parse_c_expression with
1739 *.[ch] Replaced all occurences of parse_c_1 with parse_exp_1
1741 [End of ChangeLog entries from Andrew Beers for Modula-2 support.]
1743 Mon Sep 16 17:19:46 1991 John Gilmore (gnu at cygnus.com)
1745 Small fixes from Peter Schauer:
1747 * infrun.c (child_attach): Lint.
1748 * solib.c (find_solib): Handle shared libs version 2.
1750 Small fixes from David Wood:
1752 * xm-ultra3.h (SYS_SIGLIST_MISSING): Typo.
1756 * remote-vx.c: Move <stdio.h> to top, for FILE. Fix from
1757 John S <basrai%kanga.dnet@c3po.sm-alc.af.mil>.
1759 * utils.c (wrap_here): Avoid wrap action of fputs_filtered if
1760 chars_per_line is at maximum (user typed `set width 0'). Fix
1761 from Andreas Schwab <schwab@ls5.informatik.uni-dortmund.de>.
1763 Tue Sep 17 17:31:04 1991 Stu Grossman (grossman at cygnus.com)
1765 * coredep.c: include ptrace.h where necessary.
1766 * mipsread.c(parse_lines): fix unsigned char problem that was
1767 messing up line numbers on SGI's and possibly other MIPS based
1769 * infrun.c (child_create_inferior): use better test to check
1770 return val from setpgrp().
1771 * tm-irix3.h, xm-irix3.h, tconfig/irix3, xconfig/irix3: add these
1772 for sgi/irix support.
1774 Wed Sep 18 04:33:31 1991 Per Bothner (bothner at cygnus.com)
1776 * mipsread.c (parse_symbol): Put non-static procedures
1777 in the global block.
1779 Fri Sep 13 00:14:52 1991 John Gilmore (gnu at cygnus.com)
1781 Patch together `text_start' and `text_end' for 29K port.
1783 * exec.c (exec_command): If NEED_TEXT_START_END, define the
1784 variables and set them based on the exec file.
1785 * am29k-tdep.c: declare text_start.
1786 * valops.c (call_function_by_hand): declare text_end.
1788 * inferior.h: Eliminate CANNOT_EXECUTE_STACK in favor of
1789 defining CALL_DUMMY_LOCATION as BEFORE_TEXT_END. This is
1790 because machines that do this will also have to know to
1791 set NEED_TEXT_START_END. Besides, it was a redundant way to
1793 * tm-29k.h, tm-convex.h, tm-np1.h: Eliminate
1794 CANNOT_EXECUTE_STACK, define CALL_DUMMY_LOCATION and
1795 NEED_TEXT_START_END.
1797 Thu Sep 12 00:22:24 1991 John Gilmore (gnu at cygint.cygnus.com)
1799 AMD 29000 changes from David Wood <wood@david.ultra.nyu.edu>:
1801 * Makefile.in (CLIBS): Put XM_CLIBS and TM_CLIBS at end.
1802 Pass MUNCH_DEFINE to munch whenever we run it.
1803 * am29k-pinsn.c (print_insn): Handle NOP specially. Avoid %#x
1804 format string; use 0x%x instead.
1805 * am29k-tdep.c: Use DUMMY_SAVE_GREGS and RETURN_REGNUM.
1806 * ultra-xdep.c, xm-ultra.h: New files for Ultracomputer host system.
1807 * xm-rtbsd.h: New host support for RT/PC running BSD Unix.
1808 * inflow.c: Handle `short' process group IDs.
1809 * infptrace.c (fetch_register): Support CANNOT_FETCH_REGISTER,
1810 and check for ptrace errors.
1811 * coffread.c (SDB_REG_TO_REGNUM): Define if not already.
1812 (coff_symfile_init): Initialize text_bfd_scnum.
1813 (read_coff_symtab): Use it to find the text [and absolute?] sections.
1814 * ../config.sub: Add vendor nyu and os "sym[1-9]*".
1815 * configure.in: Add hosts rtpc-*-* and a29k-*-*.
1816 Merge target arm case with other "easy" cases. Add target
1817 cases a29k-*-none (rehack of am29k), a29k-*-kern (remote to
1818 Ultracomputer kernel), and a29k-*-sym1 (ultracomputer OS's user
1820 * minimon.h, remote-adapt.c, remote-mm.c: Add.
1821 * munch: Cope with RT/PC putting fns in data segment.
1822 Restore ability to override `nm' by specifying MUNCH_NM.
1823 * xconfig/rtbsd, xconfig/ultra3: New host systems.
1824 * tconfig/a29k: Rename from tconfig/am29k. Add remote-mm
1825 and remote-adapt. Remove encapsulated coff #define's (the
1826 support should go in BFD, and gdb shouldn't know or care).
1827 * tconfig/a29k-kern: Same, but for remote kernel debugging.
1828 * tconfig/ultra3: For debugging user processes on Ultra3/Sym1.
1829 * tm-29k.h: Update BADMAG (though it should go away).
1830 Allow the register definitions to be overridden in another
1831 tm-file. Fix SR_REGNUM. Add a mess of _REGNUM's. Separate
1832 RETURN_REGNUM from GR96_REGNUM and DUMMY_SAVE_GREGS from
1833 DUMMY_SAVE_GR96, for handling kernel calling conventions
1834 that use GR64+ rather than GR96+.
1835 * tm-ultra3.h: New file, for use on Ultra3 Unix as well as for
1836 remote debugging of Ultra3 kernel. Includes tm-29k.h and
1837 overrides various things.
1839 * remote-mm.c (mm_attach, mm_wait): Handle attach like
1840 child_attach does, making a clean stop in the newly attached
1842 * remote-eb.c: Lint.
1844 * coffread.c: Make coffread independent of any particular
1845 variant of COFF. Avoid #include-ing any particular one except
1846 internalcoff.h. BFD now passes key values for symbol reading
1847 as part of its coff_data structure (LINESZ, SYMESZ, AUXESZ,
1848 and the symbol masks and shifts); use them.
1849 Remove obsolete end_of_text_addr.
1851 * exec.c: Remove unused include files.
1853 Wed Sep 11 19:38:44 1991 John Gilmore (gnu at cygint.cygnus.com)
1855 * Makefile.in (documentation targets): Pass $(M4).
1856 Bugfix from eggert@twinsun.com (Paul Eggert).
1858 * stack.c (down_silently_command): Check for stack existence.
1860 Tue Sep 10 23:08:29 1991 John Gilmore (gnu at cygint.cygnus.com)
1862 * Makefile.in (VERSION): Update to 4.0.3.
1864 Tue Sep 10 09:19:29 1991 John Gilmore (gnu at cygint.cygnus.com)
1866 * core.c (core_file_command): Print frame at coredump with
1867 its level number, by calling print_stack_frame.
1868 * frame.h: Add selected_frame_level, print_stack_frame.
1869 * frame.h, stack.c: Remove print_sel_frame, print_selected_frame.
1870 * convex-tdep.c, convex-xdep.c, infcmd.c, inflow.c, infrun.c:
1871 Change print_sel_frame and print_selected_frame callers to
1874 * dbxread.c (read_ofile_symtab): Avoid empty else clause.
1875 * symfile.c (free_named_symtabs): Ditto.
1876 * main.c (main): wrap_here needs an arg.
1877 * solib.c (find_solib): Avoid memory access if _DYNAMIC is zero.
1878 (solib_add): Avoid noise.
1879 (solib_create_inferior_hook): Lint.
1880 (sharedlibrary_command): Move dont_repeat to here.
1881 * utils.c (error): Call wrap_here to force buffered output.
1883 Small patches from Peter Schauer:
1885 * coffread.c (start_symtab): Free any existing line_vector before
1887 (read_coff_symtab): Ditto for type_vector.
1889 * source.c (lines_to_list): New variable, replacing function.
1890 (all uses): Use as variable.
1891 (_initialize_source): Add 'set listsize' and 'show listsize'.
1892 * utils.c (lines_to_list): Remove function.
1893 * stack.c (print_frame_info): Use as variable.
1894 * defs.h (lines_to_list): Remove declaration.
1896 Mon Sep 9 13:45:57 1991 John Gilmore (gnu at cygint.cygnus.com)
1898 * breakpoint.c (insert_breakpoints): Restore warning about
1899 the program might be running in another process, but only for
1900 systems with this brain death (#ifdef ONE_PROCESS_WRITETEXT).
1901 * xm-hp300bsd.h, xm-mips.h, xm-vax.h: Define it.
1903 * utils.c (error): if error_pre_print is set, print the string
1905 * main.c (main, print_gnu_advertisement, print_gdb_version):
1906 Reformat legalese so it always prints, but acts as an "I'm here"
1907 message while symbols are being read. If any errors occur,
1908 print a few newlines to set off the message and start it at the
1909 left margin. Remove mention of "help" command, and don't yak
1910 about symbol reading.
1911 (catch_errors): Error string is now printed first in case of
1913 * command.c (undef_cmd_error, lookup_cmd): On undefined command,
1914 suggest the "help" command.
1916 * Makefile.in (VERSION): Set to 4.0.2.
1918 Thu Sep 5 23:49:48 1991 John Gilmore (gnu at cygint.cygnus.com)
1920 * .gdbinit: Remove useless "rr" command. Set complaints
1921 to 1 for people debugging gdb.
1923 * breakpoint.c, remote-vx.c: Reword strings printed by
1924 catch_errors callers.
1926 Wed Sep 4 11:07:50 1991 John Gilmore (gnu at cygint.cygnus.com)
1928 * WHATS.NEW: "history write -> history save". Doc "write on/off".
1929 (Fix from kenc@viewlogic.com.)
1931 Fix some infrastructure to be able to cope with host and target
1932 machines with different sized basic types (ints, ptrs, etc).
1933 (Idea from pierre@la.tce.com (Pierre Willard).)
1935 * values.c (value_from_longest): Rename from value_from_long.
1936 Handle pointer types as well as integers, so that targets with
1937 different pointer sizes from the host can be accomodated.
1938 * breakpoint.c, convex-tdep.c, eval.c, expprint.c, printcmd.c,
1939 valarith.c, valops.c, valprint.c, value.h, values.c: Rename
1940 uses of value_from_long to value_from_longest.
1941 * eval.c, findvar.c, printcmd.c, valarith.c, valops.c: Pass
1942 the correct pointer type to value_from_long{est}.
1944 * doc/gdb.texinfo ($_, $__): Describe types of these variables.
1946 * remote-vx.c: Remove obsolete code for calling functions via
1947 vxworks kludge interface (it referenced value_from_long).
1949 * valops.c (value_string): Find malloc with lookup_misc_func, not
1952 Tue Sep 3 18:37:46 1991 John Gilmore (gnu at cygint.cygnus.com)
1954 Make writing to files work properly. (Fixes to BFD are also needed.)
1956 * core.c (core_open): Open file ourselves, read or r/w, depending on
1957 write_files. Use bfd_fdopenr.
1958 * gdbcore.h (write_files): New variable.
1959 * exec.c (write_files): Define variable, add set&show for it.
1960 (exec_file_command): Use write_files to open for read or r/write.
1962 Make shared library reading happen automatically. These changes
1963 are mostly from Peter Schauer <pes@regent.e-technik.tu-muenchen.de>.
1965 * inferior.h (stop_soon_quietly): Add to exported variables.
1966 * infrun.c (child_create_inferior): call solib hook, if defined.
1967 (child_attach): call solib hook, if defined.
1968 * solib.c: Include inferior.h. Add from_tty to so_list as kludge.
1969 (find_solib): Use lookup_misc_func rather than hand-rolled.
1970 (symbol_add_stub): New stub for catch_errors.
1971 (solib_add): Avoid output if !from_tty. Catch errors rather
1972 than just calling symbol_file_add and bombing.
1973 (solib_create_inferior_hook): Interface with the target process
1974 to let it read and alloc shared libs, then figure out what it did.
1976 * core.c (validate_files): Fix typo, soften warning.
1977 (Fix from Hiroto Kagotani <kagotani@cs.titech.ac.jp>.)
1979 * utils.c (fputs_demangled): Avoid duplicate printing if
1980 demangling is off. (Fix from J.T. Conklin <jtc@cayenne.com>.)
1982 * infrun.c (proceed): Cast -1 to (CORE_ADDR) before comparing.
1983 (Fix from pierre@la.tce.com (Pierre Willard).)
1985 * main.c (catch_errors): Change argument to a char * from an int,
1986 since a char * can point to a struct full of glop, but an int
1987 is not guaranteed to be able to hold a pointer.
1988 * breakpoint.c (breakpoint_cond_eval, bpstat_stop_status,
1989 breakpoint_re_set_one, breakpoint_re_set): Adapt.
1990 * core.c (core_open, solib_add_stub): Adapt.
1991 * remote-vx.c (symbol_stub, add_symbol_stub, callers): Adapt.
1993 Wed Aug 28 18:18:05 1991 John Gilmore (gnu at cygint.cygnus.com)
1995 * Makefile.in: Update VERSION to 4.0.1. Evade GNU Make bug
1996 by adding .NOEXPORT target.
1998 Fri Aug 23 17:14:25 1991 John Gilmore (gnu at cygint.cygnus.com)
2002 * Makefile.in (VERSION): Roll to 4.0.
2003 (gdb.tar.Z): Make refcard.ps as well, for shipment.
2005 Fri Aug 23 14:07:09 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
2007 * doc/gdb.texinfo: minor rewordings, crossref to ptype from print,
2010 * doc/Makefile, Makefile.in: generate "gdb-all.texi" rather than
2013 * doc/rdl-apps.texi: renamed from rdl-apps.texinfo
2015 * Makefile.in, doc/Makefile, doc/.Sanitize, doc/gdb.texinfo:
2016 reflect above name change
2018 * WHATS.NEW: correct pointer to refcard.
2020 * doc/gdb.texinfo: update New Features, Installing
2022 * doc/gdbint.texinfo: add short description of configure +template
2024 Fri Aug 23 11:46:08 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
2026 * doc/gdb.texinfo: update, fix bugs in "Installing" appendix
2028 Fri Aug 23 01:02:00 1991 John Gilmore (gnu at cygint.cygnus.com)
2030 * Makefile.in: Add config.sub, make doc/rdl-apps.texinfo for
2031 tar file, add dependencies for referenced doc files.
2033 Thu Aug 22 22:17:06 1991 Stu Grossman (grossman at cygint.cygnus.com)
2035 * coffread.c, symfile.c, stack.c: saberized.
2037 Thu Aug 22 16:20:27 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
2039 * doc/refcard.tex: permuted Essential Commands sec
2041 * doc/gdb.texinfo: new C++ chapter; revised installation appendix;
2043 set/show symbol-reloading
2044 default set complaints 0
2046 RET-repeat disabled after prompted long displays
2047 processID (attach) interpretation of 2nd GDB cmdline arg
2049 Thu Aug 22 14:05:47 1991 Stu Grossman (grossman at cygint.cygnus.com)
2051 * expread.y, coffread.c, dbxread.c, target.c, mem-break.c,
2052 cplus-dem.c, values.c, valprint.c, symfile.c, remote.c,
2053 breakpoint.c, main.c: lint.
2055 Thu Aug 22 02:02:26 1991 John Gilmore (gnu at cygint.cygnus.com)
2057 Install new configuration scheme for GDB and friends.
2059 * config.sub: Translate ordinary names to three-part names.
2060 * configure: Use three-part names internally.
2061 * configure.in: Translate three-part names to filenames.
2063 * README, WHATS.NEW: Update for gdb-4.0.
2064 * Makefile.in: Roll VERSION to 3.99.
2066 Wed Aug 21 18:21:09 1991 John Gilmore (gnu at cygint.cygnus.com)
2068 * infptrace.c (KERNEL_U_ADDR_BSD): Include a.out.gnu.h.
2069 * i960-tdep.c, m68k-tdep.c, sparc-tdep.c, tm-i960.h,
2070 tm-m68k.h, remote-nindy.c: Change ext_format_XXX structs
2071 to single structures rather than arrays; when passing
2072 their address, use &. This avoids trouble with bdead compilers.
2073 * mcheck.c: Don't include <stdlib.h>; just declare "void abort();"
2074 instead. This avoids portability headaches.
2075 * mips-tdep.c (mips_do_registers_info): Only print FP regs if
2077 * source.c (open_source_file): Avoid ANSI const bdeath by
2078 skipping declaration and then casting result value.
2079 * tm-hp300bsd.h: Clarify comment.
2080 * utils.c (strstr): Result is const char *; ANSI bdeath.
2081 * xm-hp300bsd.h: Define HOST_BYTE_ORDER. Redefine INT_MIN,
2082 since system include file defines it differently from "defs.h",
2083 though the two are equivalent for our purposes.
2084 * tconfig/hp300bsd: Add m68k-tdep.o.
2086 Tue Aug 20 16:01:11 1991 John Gilmore (gnu at cygint.cygnus.com)
2088 * tconfig/sun*4: Remove warnings about system assembler.
2090 Mon Aug 19 13:44:46 1991 John Gilmore (gnu at cygint.cygnus.com)
2092 * mcheck.c: Avoid warning about undeclared abort fn.
2093 * tm-sparc.h (PC_ADJUST): Avoid calling error() from this;
2094 it causes recursive calls to error() when used in cleanups.
2095 To do so requires that we make it a function, so we do.
2096 * sparc-tdep.c (sparc_pc_adjust): New implem of PC_ADJUST.
2097 * utils.c (do_cleanups): Remove the current cleanup from the
2098 chain *before* calling it, in case error() is called from it.
2099 The result won't be pretty, but won't be an infinite loop either.
2101 Mon Aug 19 00:41:04 1991 Michael Tiemann (tiemann at cygint.cygnus.com)
2103 * dbxread.c (read_struct_type): Grok anon structs for C++.
2104 (vb_name, vptr_name): Null terminate these strings.
2106 Fri Aug 16 08:31:03 1991 John Gilmore (gnu at cygint.cygnus.com)
2108 Minor bug fixes from BSD Net2 gdb:
2110 * blockframe.c (get_prev_frame_info): If FRAME_CHAIN_COMBINE
2111 returns 0, there is no previous frame.
2112 * breakpoint.c (commands_command): If !from_tty, don't call
2113 input_from_terminal_p().
2114 * dbxread.c (record_misc_function): Speed up slightly.
2115 (compare_psymbols): Ditto.
2116 * infcmd.c (do_registers_info): Take a second argument to
2117 determine whether to print float registers. "info registers"
2118 does not do so anymore. "info all-registers" does, now.
2119 * mips-tdep.c, pyr-tdep.c (xxx_do_registers_info): Take second
2121 * tm-mips.h, tm-pyr.h (DO_REGISTERS_INFO): Pass second arg.
2122 * inflow.c (initialize_inflow): Set tflags_ours correctly.
2126 * breakpoint.c (bpstat_do_actions): Use a cleanup to restore
2127 executing_breakpoint_commands if we are interrupted by error.
2128 * coffread.c (init_lineno): Avoid problem with zero-sized linetab
2129 versus malloc/free. From: john@labtam.labtam.oz.au (John Carey).
2130 * core.c (solib_add_stub, core_open): Call SOLIB_ADD inside a
2131 catch_errors() so we can setup the frame regardless of whether
2132 the shared libs work.
2133 * ieee-float.c (double_to_ieee_extended): Get exponent from
2134 right place in little-endian systems. From John Carey.
2136 Thu Aug 15 18:43:57 1991 John Gilmore (gnu at cygint.cygnus.com)
2138 * main.c: Remove unused terminating_signals and catch_termination().
2139 (long_options): Terminate with a zero element.
2140 [Bugfix from Atsuo Kawaguchi <atsuo@hark86.harl.hitachi.co.jp>.]
2141 (gdb_readline): Make call-compatible with readline.
2142 (init_signals): Improve comments re vfork vs. signal.
2144 * utils.c (prompt_for_continue): Use new gdb_readline().
2145 If we prompt for continuation, we don't let CR repeat the previous
2146 command, once we get back to a prompt. It's too easy to keep
2147 hitting CR, expecting "--more--" prompts, and have some long
2148 command start repeating on you.
2150 Tue Aug 13 16:17:56 1991 John Gilmore (gnu at cygint.cygnus.com)
2152 * blockframe.c (frameless_look_for_prologue): Speed up by
2153 calling SKIP_PROLOGUE_FRAMELESS_P if it's defined.
2154 * tm-sparc.h (SKIP_PROLOGUE, SKIP_PROLOGUE_FRAMELESS_P):
2155 Define two variants, one faster.
2156 * sparc-tdep.c (sparc_frame_chain): Use target_read_memory
2157 and return zero, rather than giving an error.
2158 (setup_arbitrary_frame): Initialize the PC in the new frame.
2159 (skip_prologue): Add a second arg saying whether we're just
2160 checking for a frameless function or not.
2162 * core.c (core_open, core_close, core_xfer_memory): Move
2163 section table pointers and bfd* into the target_ops.
2164 (core_open): Allow errors in shared lib reading, etc.
2165 (core_files_info): Describe shared library sections.
2167 * exec.c (exec_open, exec_close, exec_xfer_memory, xfer_memory,
2168 exec_files_info, set_section_command): Move section table
2169 pointers and bfd* into the target_ops.
2170 (add_to_section_table): Add BFD to section table.
2172 * target.c (target_xfer_memory, target_info): Pass target to
2173 xfer_memory and target_info functions.
2176 * gdbcore.h: Move struct section_table.
2177 * target.h: New home of struct section_table.
2179 * solib.c (solib_add): New argument is the target_ops whose
2180 section list is to be added to, if any. Reallocate the
2181 sections in that target to add any that come from shared libs.
2182 (throughout) so_sections renamed to sections.
2183 (solib_xfer_memory): Deleted.
2184 * tm-sunos.h (SOLIB_ADD): Add target argument.
2185 (SOLIB_XFER_MEMORY): Delete.
2187 * core.c, exec.c, inftarg.c, remote-eb.c, remote-nindy.c,
2188 remote-vx.c, remote.c, target.c, target.h: Remove add_syms vector
2189 from target_ops. It's the same on all targets. Add two section
2190 pointers to target_ops.
2192 * stack.c (find_relative_frame): Dump ancient algorithm for
2193 "down", just use handy "next" pointers.
2194 (frame_command): Don't error if there is no stack; let user
2197 * inflow.c (new_tty_prefork, new_tty): New prefork routine
2198 modifies static state in the parent process; new_tty itself
2199 runs in the child and modifies the child's file descriptors
2200 to match the saved static state.
2201 * infrun.c (child_create_inferior): Call new_tty_prefork,
2204 * infptrace.c (child_xfer_memory): Add ignored target arg.
2205 * remote-eb.c (eb_xfer_inferior_memory): ''
2206 * remote-nindy.c (nindy_xfer_inferior_memory): ''
2207 * remote-vx.c (vx_xfer_memory): ''
2208 * remote.c (remote_xfer_memory): ''. Rename from
2209 remote_xfer_inferior_memory.
2211 * main.c (main): Only try to attach "corefile" argument if
2212 it starts with a digit.
2214 * symfile.c (symbol_reloading): New "set/show" variable.
2215 (symbol_file_add): Shorten message about symbol reading.
2216 (add_symbol_file_command): Merge with add_syms_addr_command,
2217 since this should work on all targets now.
2218 (stop_whining): Default to zero, to shut up complaints
2219 about bad symbol tables on many systems.
2220 (free_named_symtabs): Just exit unless symbol_reloading.
2222 * xm-sun3os4.h, xm-sun4os4.h: Define BROKEN_LARGE_ALLOCA,
2223 and add comment explaining shared library screw.
2225 * source.c: #if defined => #ifdef.
2227 Thu Aug 8 12:23:19 1991 John Gilmore (gnu at cygint.cygnus.com)
2229 * doc/gdbint.texinfo: Improve doc on porting to new OS's.
2231 Tue Aug 6 17:16:15 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
2233 * doc/rdl-apps.texinfo: provide default readline-appendix finder
2234 (doc/Makefile knows how to make one for local config)
2236 * Makefile.in: use doc/Makefile for doc targets
2238 * doc/Makefile: GDB documentation now has its own Makefile
2239 doc/refcard.tex: renamed from "gdbrc.tex"
2240 doc/.Sanitize: add Makefile; recognize renamed refcard.tex
2241 doc/gdbint.texinfo: add markup in "Cleanups" chapter
2244 Fri Aug 2 00:13:06 1991 John Gilmore (gnu at cygint.cygnus.com)
2246 * values.c (baseclass_addr): When reading target memory, use the
2247 length of the basetype, not the upper type. We've only malloc'd
2248 enough space for the basetype, leading to errors in free().
2250 * expprint.c (print_subexp): Print UNOP_MEMVAL of an OP_LONG that
2251 ends up as a function specially, since we know the actual type of
2252 the pointed-to address. This (somewhat) fixes display of
2253 expressions that include misc_function_vector names. Try `cond 1
2254 !strcmp("a","b")' then `i b'.
2256 * infrun.c: Move DO_DEFERRED_STORES from proceed() to resume().
2257 The child can be proceeded from inside wait_for_inferior in
2258 evaluating breakpoint conditions, and DO_DEFERRED_STORES was
2259 getting skipped in that case.
2261 * expprint.c (print_subexp): Use filtered output, since the
2262 subroutines we call use it, otherwise the output is horribly
2263 mangled, since output of wrappable stuff comes out late.
2265 * Makefile.in: Bump VERSION to 3.98.1
2267 * infrun.c (child_create_process): Use execlp to find the
2268 shell to exec our target program. This requires some fiddling
2269 with `environ' since there is no execlpe().
2271 Thu Aug 1 15:35:17 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
2273 * Makefile.in, doc/gdbrc.tex, doc/rc-* (new files):
2274 Minor rearrangement of refcard permits two new make targets--
2275 gdbrc.dvi DVI output for refcard, using CM fonts
2276 gdbrc.ps PostScript refcard, using PS fonts
2278 Wed Jul 31 16:46:21 1991 John Gilmore (gnu at cygint.cygnus.com)
2282 * TODO, Projects, WHATS.NEW, README: Update for gdb-3.98.
2283 * Makefile.in (gdb-all.texinfo): Avoid touching file if M4 dies.
2285 Wed Jul 31 16:35:58 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
2287 * doc/gdb.texinfo: last changes for release.
2288 Minor typo and formatting fixes; incorporated most fixes remaining from
2289 filed mail commenting on earlier drafts.
2291 Added warnings: pipes don't work in run command;
2292 conditions are converse of assertions;
2293 step over fn without debug info goes to next fn;
2294 vars may have "wrong" values near fn entrance, exit
2296 Added example from Kingston on printing repeated nonadjacent values
2298 Added explicit mention that in Emacs gdb mode C-c and C-z are like
2299 shell mode for signals
2301 Renamed "Stepping and Continuing" to "Continuing and Stepping" so it
2302 doesn't sound so much like its parent "Stopping and Continuing"; also
2303 moved entries on continue to top of section, so they don't get lost.
2305 Improved installation directions in appendix, added manual formatting
2308 Tue Jul 30 17:26:39 1991 John Gilmore (gnu at cygint.cygnus.com)
2310 * configure.in: Remove xm.h and tm.h even if we aren't linking
2311 new ones, so "./configure sun4; ./configure none" does the right
2312 thing. Assume that alldeps.mak and depend are already built in
2313 srcdir, and avoid running "make" (particularly "make depend",
2314 which involves "gcc") from inside configure. Build Makefile
2315 directly rather than building Makefile.conf first.
2316 * configure: Regenerate with above changes.
2317 * Makefile.in: Use $(BISON) to find bison. Roll VERSION
2318 to 3.98. Revise gdb.tar.Z procedure to produce a file
2319 called gdb-$(VERSION).tar.Z but which unpacks into a
2320 directory called "gdb". Move non-source files out of
2321 $(SFILES_SUBDIR). Pretty up alldeps.mak with comments.
2322 (depend): Don't try to do "gcc expread.y".
2323 (expread.o): Update dependencies by hand.
2325 Mon Jul 29 15:21:09 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
2328 Fixed a variety of small typos that prevented info from formatting
2329 cleanly; altered too-long heading for GPL Appendix, as discussed
2330 w/RMS; Changed date on cover to July 91.
2332 Fri Jul 26 13:20:02 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
2335 (1) Applied some fixes due to comments from Larry Breed (easier ones
2336 through chapsec 5.2)
2337 (2) Eliminated use of @footnote---had my doubts about it anyways, and
2338 it's broken in latest texinfo
2339 (3) Introduced *some* use of [] for optional arguments, where
2340 explanation is not simpler by listing cmd w arg and cmd w/out arg
2341 separately. Still not using @deffn.
2342 (4) Dropped in GPL-2. NOTE: one of GPL-2 or texinfo is broken; a
2343 couple of headings are too long. Need patches to texinfo or revision
2346 * Partial update to README (which still needs work for this
2347 release!): (1) use of configure corrected for new script,
2348 (2) "make gdb.dvi" and "make gdb.info" mentioned.
2350 Wed Jul 24 06:44:02 1991 John Gilmore (gnu at cygint.cygnus.com)
2352 * symtab.c (lookup_symbol): Don't complain right off about
2353 no debug symbols; use the misc function vector first.
2354 (list_symbols): Use misc function vector to find symbols
2355 that don't have debug info, and print them.
2356 (find_pc_symtab): Temporarily avoid fatal() when psymtab
2357 PC range doesn't match symtab PC range, as it does on the
2358 MIPS because our symtab reading isn't perfect.
2360 * dbxread.c (dbx_symfile_read): Make warning about
2361 "no debug symbols" slightly nicer.
2363 * source.c (select_source_symtab): If "main" symbol exists,
2364 but decode_line_spec can't find line info, don't just return
2365 a zero; try other source symtabs or give an error.
2367 * mipsread.c (parse_partial_symbols): Sort the psymtabs by
2368 their low addresses first, then rip through fixing high addrs.
2370 * ns32k-opcode.h (sfsr): Bugfix from Rune Nerg}rd,
2371 <runene@ifi.uio.no>.
2372 (NS32K_SVC_IMMED_OPERANDS): Reverse the #ifndef.
2374 Tue Jul 23 18:52:43 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
2376 * Minor, mostly mechanical, cleanup of doc subdir for clean
2377 makeinfo'ing and TeXing; also ensured gdb-all.texinfo (post-m4)
2378 and gdb.info (post- texinfo2 makeinfo) generated for distribution.
2380 Sun Jul 21 03:54:52 1991 John Gilmore (gnu at cygint.cygnus.com)
2382 Mostly MIPS and general symbol-reading fixups.
2384 * doc/gdbint.texinfo: Add documentation on symbol-reading
2387 * mipsread.c: Remove kludges around #include "ecoff.h".
2388 Remove redefinitions of a_magic, etc, no longer used.
2389 (parse_symbol, ): Convert "Internal:" printfs to complain()ts.
2390 Fix global overview comments to match symfile.c protocol.
2391 (mipscoff_new_init): Eliminate cur_hdr if we have one.
2392 (mipscoff_symfile_read): Eliminate unused code. Avoid
2393 sorting all the symtabs, when all we have read here is psymtabs.
2394 The symtabs are sorted as they are created anyway. Tell
2395 condense_misc_bunches whether we're mainline.
2396 (psymtab_to_symtab_1): Pass filename when recursing, to make
2397 stack trace more informative.
2398 (parse_partial_symbols): Assume cur_hdr as argument.
2399 (read_mips_symtab): Don't clobber cur_hdr, so it can be freed.
2400 Pass cur_hdr implicitly to parse_partial_symbols. Avoid checking
2401 the TYPE_NAME of char *, since that's done in symfile.c.
2402 (free_numargs, parse_symbol, add_symbol, add_block,
2403 shrink_linetable): Declare these fns void.
2404 (upgrade_type): Convert tree of if's to switch. Clean up
2405 bogus "off == 0" handling with a complaint. Avoid setting
2406 field bitpos and bitsize of array with lower and upper bounds.
2407 Check specified bitsize of elements against their actual type's
2408 bitsize, and complain if different. Complain about unknown
2410 (parse_fdr): Don't assume sizeof(char *) == sizeof (struct *).
2411 (psymtab_to_symtab_1): Print names of subsidiary files that
2412 are being read in. FIXME, we read far too many files. This code
2413 is not the problem, the problem is in parse_fdr where the psymtabs
2415 (cross_ref): Result should indicate that we used one aux entry
2416 normally, or two if we encountered a "next" entry. This used
2417 to leave the caller pointing at the wrong aux entry.
2418 (add_symbol): If overflowed cur_block, reallocate it larger,
2419 chase all pointers to it, and complain(), rather than clobber memory.
2420 (shrink_block): Use xrealloc rather than xmalloc-and-copy.
2421 (new_field): Only allocate one field initially, not two.
2422 Pull ++ out of macro argument. Simplify.
2423 (_initialize_mipsread): Avoid initialization of importd
2424 global_psymbols and static_psymbols.
2426 * symfile.c (psymtab_to_symtab): Depend on XXX_psymtab_to_symtab
2427 to properly set pst->symtab; avoid searching for it.
2428 (symfile_fns): Improve comments, add a FIXME.
2429 * dbxread.c: Update comments to reflect symfile protocol.
2430 (read_ofile_symtab, end_symtab): Return the symtab.
2431 (psymtab_to_symtab_1): Set pst->symtab.
2433 * coffread.c (coff_symfile_read): tell condense_misc_bunches
2434 whether we're mainline.
2436 * symfile.h (sym_fns): Remove unused sym_discard member.
2437 * coffread.c, mipsread.c, dbxread.c: Remove XXX_symfile_discard.
2439 * mtrace.c (mtrace): Take effect if mallwatch is set, even if
2440 the environment variable is not.
2441 * infcmd.c (finish_command): Use filtered printfs.
2442 * cplus-dem.c: Add struct tags to a few unnamed structs.
2443 * valops.c (value_coerce_array): Improve comments.
2444 * valprint.c (type_print_varspec_suffix): Print array size only
2445 if greater than zero.
2446 * m88k-tdep.c: Shift some lines left by one space, that had
2447 apparently been trashed at some point.
2448 * TODO: More things to do, a few got done.
2450 Thu Jul 18 22:46:05 1991 John Gilmore (gnu at cygint.cygnus.com)
2452 * symtab.h (LOC_EXTERNAL): Eliminate in favor of LOC_STATIC.
2453 (ldsymoff, ldsymlen, globals_offset, statics_offset): Improve
2455 * dbxread.c (read_dbx_symtab): LOC_EXTERNAL -> LOC_STATIC.
2456 * expread.y, findvar.c, symmisc.c: Ditto.
2457 * printcmd.c (address_info): Update printed forms of LOC_
2458 symbols. Elim LOC_EXTERNAL.
2459 (print_frame_args): Keep track of param stack offsets before
2460 re-looking up to find the local register param is kept in.
2462 * mipsread.c: Use <symconst.h> and <sym.h> rather than <syms.h>.
2463 Further integration of mipsread into gdb. Eliminate unused
2464 routines, duplicate declarations. Handle static symbols in
2465 psymtabs as well as external symbols. When reading symtabs,
2466 insert symbols into the correct block (global, static, or a local
2468 (read_mips_symtab, parse_partial_symbols): Don't pass useless
2470 (mipscoff_symfile_read): Don't call select_source_symtab.
2471 (parse_symbol): Use SYMBOL_VALUE_ADDRESS where appropriate,
2472 rather than SYMBOL_VALUE.
2473 (parse_external): Comment clobbering of top_stack.
2474 (parse_partial_symbols): Update comments. Allocate and parse
2475 static symbols as well as external symbols. FIXME, enum values
2476 are not handled in this pass, but should be. Inline new_psymbol.
2477 Use SYMBOL_VALUE_ADDRESS.
2478 (psymtab_to_symtab_1): Read symbols into global static block
2479 by default (until enter some function's local block context).
2480 (sort_blocks): Clean up STATIC_BLOCK as well as GLOBAL_BLOCK.
2481 (destroy_all_symtabs, new_psymbol): Eliminate, unused.
2483 * source.c (select_source_symtab): Select a source symtab
2484 from either the symtabs or, failing that, the psymtabs.
2485 (list_command): Update error message.
2486 (forward_search_command, reverse_search_command): Use getc, not
2487 fgetc, for speed. FIXME, add comment about buffers that die if
2488 overrun by long line.
2490 * values.c (unpack_field_as_long, modify_field): Avoid shifting
2491 by an entire word, which is not portable, if we have a 32-bit
2492 field. (Code in dbxread.c already turns such bitfields, if
2493 aligned, into ordinary ints, but fixing this will help for other
2494 symbol formats and for future changes.)
2495 * core.c (core_open): Handle ANSI const brain death.
2496 * utils.c (vprintf): Fix varargs typo.
2498 Sun Jul 14 00:42:53 1991 John Gilmore (gnu at cygint.cygnus.com)
2500 * findvar.c (find_var_value): Handle &function better.
2501 * TODO: Document work needed on &fn and &array.
2502 * printcmd.c (print_address_symbolic): New arg is the prefix
2503 to print if a name is printed.
2504 (print_address_demangle): Honor "set print address" now.
2505 Use new arg above to improve spacing of output.
2506 * valprint.c (val_print): When printing function pointers,
2507 print symbolic form too.
2508 * breakpoint.c (breakpoint_1): Use new print_address_symbolic.
2510 Mon Jul 8 19:02:46 1991 John Gilmore (gnu at cygint.cygnus.com)
2512 * core.c (memory_error): Reword error msg to mislead less.
2514 * mips-pinsn.c (print_insn_arg 'd'): Print $ with reg name.
2516 * mipsread.c (read_mips_symtab, read_the_mips_symtab,
2517 parse_partial_symbols): Use newer BFD internals (external_filehdr
2518 and external_aouthdr), byte-swap the fields that we care about
2519 before using them, and make the file header data local to
2520 read_the_mips_symtab rather than global.
2522 Sat Jul 6 01:34:15 1991 John Gilmore (gnu at cygint.cygnus.com)
2524 * ns32k-opcode.h (movmw, movmd): Fix opcodes. Bug fix
2525 from Rune Nerg}rd <runene@ifi.uio.no> on 5 Jul 1991.
2527 * main.c (command_line_input): Flush stdout and stderr
2528 before every call to readline. This reportedly fixes a bug
2529 that comes up in Sys V running emacs-gdb and/or xxgdb,
2530 when stdin/out are pipes or sockets.
2532 Thu Jul 4 14:47:06 1991 John Gilmore (gnu at cygint.cygnus.com)
2534 * configure.in, Makefile.in: Avoid rebuilding "depend" as much.
2535 Avoid declaring Makefile dependencies, because GNU Make stupidly
2536 tries to update it if we do.
2538 * coffread.c: Revise for minor changes to bfd internal coff
2541 * configure: If -template= is given a relative path, make it
2542 absolute before recurring in subdirectories.
2544 * configure, configure.in, Makefile.in: Install "configure" script
2545 as replacement for config.gdb.
2546 * config.gdb, Makefile.dist, Makefile.sdir: Remove
2547 * README: Update for configure, mostly. FIXME.
2549 * Add dec3100 as equivalent to littlemips. Indicate in all host &
2550 target config files that they are for the host. When the lines
2551 get copied into the Makefile, this makes it more obvious what's
2554 Mon Jun 24 23:49:07 1991 John Gilmore (gnu at cygint.cygnus.com)
2556 * sparc-opcode.h (trap opcodes): Avoid leading spaces or
2557 tabs, which end up in the disassembler output inadvertently.
2559 Wed May 29 23:01:03 1991 John Gilmore (gnu at cygint.cygnus.com)
2561 Make it compile cleanly in an ANSI GCC2 environment.
2563 * blockframe.c: <stdio.h>
2564 * cplus-dem.c: free takes a void *, ifdef __STDC__
2565 * dbxread.c (read_huge_number): avoid gcc2 bug hoisting calc of
2567 * defs.h (alloca): Avoid doing anything if alloca already def'd.
2568 * stddef.h, stdlib.h: Remove these files.
2569 * symtab.c: Avoid declaring qsort, close.
2570 * symfile.c: Avoid declaring close.
2571 * utils.c (vprintf): Declare "ap" arg as proper va_alist.
2572 * sparc-tdep.c: Avoid including lots of Sun-host-specific files.
2574 Assorted other changes.
2575 * dbxread.c: include "libaout.h", not "liba.out.h".
2576 * printcmd.c (print_frame_args): Set recurse properly for
2577 indentation of struct and array parameters.
2578 * valops.c (value_cast): Allow cast to void.
2579 * infrun.c (resume): If NO_SINGLE_STEP, call machine dependent
2580 single_step() in a target-independent fashion.
2581 * sparc-tdep.c (single_step): Don't call ptrace ourselves, just
2582 set up to be ready to continue. This makes us target independent.
2583 * infptrace.c (child_resume): Remove call to single_step; now
2584 can single step a SPARC target of any kind.
2586 Wed May 22 18:18:24 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
2588 * Makefile.dist, doc/gdb.texinfo, doc/*-m4.texinfo: split up GDB
2589 docn into separate sections---basically chapters, plus two loose
2590 pieces that can be configured to go in different places. This
2591 allows GNU m4 to preprocess the manual without coredumping.
2593 * Makefile.dist: tell TeX where to find texinfo.
2595 Mon May 20 12:15:04 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
2597 * Makefile.dist, doc/gdb.texinfo: respectively create, and use,
2598 the new target "rdl-apps.texinfo" which captures the Makefile
2599 variable that records where to find the Readline libraries.
2601 Sun May 19 05:36:59 1991 John Gilmore (gnu at cygint.cygnus.com)
2603 * tahoe-pinsn.c: #include "tahoe-opcode.h", not "opcode.h".
2604 * tm-tahoe.h (FIX_CALL_DUMMY): Ignore more parameters.
2605 * defs.h (const, volatile): Only define if not already defined.
2606 * Makefile.dist (gdb.tar.Z): Create doc subdir w/out CVS/RCS crud.
2608 * README: Update for release 3.95.
2609 * config.gdb: Don't create readline dir in subdir builds.
2610 * main.c: Include with "..." form for non-system include files,
2611 so "gcc -MM" for "make depend" works.
2612 Include readline files with "...h" rather than <readline/...h>.
2613 * mipsread.c: Include "ecoff.h" rather than "intel-coff.h".
2615 * coffread.c: Undo minor damage done by Rich Pixley. Use
2616 different internal and external representations of COFF
2617 data structures. Use new BFD routines for swapping them in and
2619 * symfile.c (free_named_symtabs): Avoid freeing file names that
2620 are null or empty. Old i960 tools seem to produce files that
2621 claim to have empty names, causing each successive file read
2622 to blow away the previous one.
2623 * sparc-xdep.c (deferred_stores): Repair minor damage by Rich.
2624 Move deferred_stores to top of file, but don't separate its
2625 #define's from its variable. Add commentary.
2626 * Makefile.dist: Fix Rich damage; undo "configure" changes in
2627 favor of keeping the (working) config.gdb. Move readline
2630 Fri May 17 12:49:56 1991 Per Bothner (via gnu at cygint.cygnus.com)
2632 * dbxread.c (read_struct_type): Try to handle g++ version 1 MI
2634 * infptrace.c (fetch_registers): no result, since now void.
2635 * tconfig/news: target depends on m68k-tdep too.
2637 Fri May 17 14:40:14 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
2639 * Makefile.dist: added readline/inc-*.texinfo to dependencies for
2642 * readline/inc-history.texinfo, readline/inc-readline.texinfo:
2643 applied various small fixes due to or inspired by RMS comments
2645 * doc/gdb.texinfo: finished using all RMS comments, save those for
2646 appendices on readline and cmd history (which are in other source
2649 Thu May 16 18:06:05 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
2651 * doc/gdb.texinfo: (1) Updated w/ref to RMS comments through
2652 chapter 9; (2) documented 'break' command's menu mode for
2653 overloaded names, in response to hgs problem report C++ p-31
2655 Wed May 15 11:02:48 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
2657 * doc/gdb.texinfo: (1) better introductory example; (2) more
2658 consistent use of @code, @samp, @file, @kbd throughout; small
2659 cleanups to first three nodes; (3) new "Contributors" node;
2660 (4) Appendix, Renamed Commands; (5) divert specialized startup
2661 instructions to "Targets" chapter for generic manuals, while
2662 leaving them up front for manuals specific to specialized
2663 environments; (6) apply fixes from RMS comments through chapter 4.
2665 * pretex.m4: modify explanatory text slightly (and redefine
2666 "regexp") to keep GNU m4 from complaining. (It still crashes
2667 later, but one step at a time...)
2669 Wed May 15 10:32:12 1991 John Gilmore (gnu at cygint.cygnus.com)
2671 * readline/readline.c (update_line): Avoid dereferencing a pointer
2672 before comparing it to its bounds. Saber caught this.
2673 (init_terminal_io): Don't set BC from the "pc=" termcap variable,
2674 and only set PC if tgetstr returned non-null. Saber caught this.
2676 Tue May 14 16:29:53 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)
2678 * Makefile.dist: put gdb.dvi stuff (updated to use M4 preprocessor
2679 stuff for config manual) here where it counts; updated
2680 to use new subdir structure (gdb/doc/).
2682 * Makefile: generated from above via
2686 * gdbint.texinfo: added instructions on generating gdb.info* files
2687 locally for release. These are ordinary info
2688 files, formatted from gdb.texinfo (via gdb-all.texinfo, see
2689 Makefile)---but due to use of texinfo 2, can't count on makeinfo
2690 to generate these, so we distribute them already formatted.
2692 * gdb.texinfo: included full Info node and menu crud (as generated
2693 by C-u M-x texinfo-master-menu using the texinfo-2 elisp code).
2695 * Makefile: updated "gdb.dvi" target to use M4 preprocessor;
2696 put in comments-for-future gdb.info target (one day makeinfo will
2699 Tue May 14 13:51:36 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)
2701 * gdb.texinfo: Updated to include new or old undocumented
2702 commands, at least the following (perhaps some others I forgot to
2703 record): info f, info float, info path, info program, info s, info
2704 set, info source, info terminal, info types, info user, set/show
2706 Also covered all recent GDB command renames for v4.
2708 Mon May 13 14:57:46 1991 John Gilmore (gnu at cygint.cygnus.com)
2710 * mipsread.c: Rather than keeping count of how many symtabs
2711 and psymtabs we have, for sorting purposes, count them when
2712 we need to sort. This fixes bug in rereading of symbol tables.
2714 Fri May 10 15:43:33 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)
2716 * infcmd.c: renamed "info path" to "show paths"

2730 * coffread.c, exec.c, infptrace.c, inftarg.c, remote.c, solib.c,
2731 symtab.h, target.c, target.h: Lint.
2732 * core.c: setup and select frame after reading shared libs,
2733 else reading shared libs will clobber them. Lint.
2734 * utils.c (error): Force out any buffered wrap text.
2736 Fri May 3 22:01:56 1991 John Gilmore (gnu at cygint.cygnus.com)
2738 * remote.c: Remove decls of memory_insert_breakpoint
2739 and memory_remove_breakpoint, no longer used. (Suggestion of
2742 * Makefile.dist: use ${subdir} in paths of BFD and LIBIBERTY,
2743 to make it easier to interface to "configure"'d libraries.
2745 Fri May 3 13:10:01 PDT 1991 Roland Pesch (pesch at fowanton.cygnus.com)
2747 * valprint.c: introduce "set p", "set pr", "show p" and "show pr" as
2748 aliases for set/show print.

2800 dc_dcontext_t not int.
2802 * coffread.c [TDESC]: Use system include files not <intel-coff.h>.
2804 * coffread.c [TDESC]: Move setting of debug_info from
2805 coff_symfile_read to find_linenos and make it work with BFD.
2807 * cplus-dem.c [__STDC__]: Make x{m,re}alloc return void*.
2809 * signame.c: Cast const char* to char* when assigning to sys_siglist.
2811 * utils.c (strsave): Make arg const char* not char*.
2813 * infrun.c (wait_for_inferior) [SHIFT_INSN_REGS]: Use

2834 Mips bringup and general cleanup
2836 * cplus-dem.c: Move CPLUS_MARKER define to after defs.h.
2837 * infptrace.c (PT_WRITE_D, PT_READ_D): Use correct values.
2838 (This still doesn't seem to make MIPS bkpts work.)
2839 * mipsread.c: Remove dup "Reading symbol data..." msg.
2840 (symbol_file_command, add_file_command): Remove, obsol.
2841 * printcmd.c (ptype_command): Say "an enum" rather than "a enum".
2842 Wrap output appropriately.

2844 selected_frame rather than target_has_stack or coredumping.
2845 * valprint.c (type_print_varspec_suffix): Wrap "ptype" output of
2846 enums appropriately.
2848 Wed May 1 14:10:22 1991 Jim Kingdon (kingdon at cygint.cygnus.com)

2852 * cplus-dem.c: Include defs.h and param.h.
2853 Makefile.dist: Don't hack in the "param.h".
2854 param.h: Don't include defs.h.

2857 can have both ints and enum type_pieces in it.
2858 ({push,pop}_type_int): New functions.
2860 Tue Apr 30 13:18:58 1991 Jim Kingdon (kingdon at cygint.cygnus.com)

2872 symtab.c, cplus-dem.c, value.h, expread.y, valprint.c,
2873 copying.awk, solib.c, inflow.c, symmisc.c
2874 : Lint. Use read_memory not read_memory_integer on CORE_ADDR's.
2875 Use {value_as,unpack}_pointer (added to values.c)
2876 not {value_as,unpack}_long on CORE_ADDR's.
2877 Use longest_to_int (added to defs.h) instead of cast to int.
2878 Remove from_tty arg to mod_path.
2879 Put symfile_bfd in {coff,dbx}read.c not symfile.h.
2880 Use OP_NULL instead of 0 where dummy enum exp_opcode needed.

3365 * tm-i386v.h (FLOAT_INFO): Don't define it, since the code
3366 for printing the float info is host-dependent, not
3367 target-dependent. FIXME.
3368 * i386-pinsn.c: Move #includes to top, remove useless ones.
3369 * i386-tdep.c: Don't bother including <.../reg.h> since we
3370 don't use it (and it doesn't exist on host systems).
3372 * ieee-float.c (ieee_extended_to_double): Convert NaN to Inf.
3373 Convert negative numbers properly.
3374 (ieee_test): Make numbers really random; fix format arg.
3376 * infcmd.c (attach_command, detach_command): Don't repeat on CR.
3377 * core.c (core_detach): Unpush core_ops, which might not be on
3378 top. We used to just pop the top, which broke things. Don't
3379 need dont_repeat() any more.
3380 (core_file_command): Psst! Don't repeat it.
3381 * remote-nindy.c (nindy_detach): Don't need dont_repeat() now.
3382 * expprint.c (print_subexp): Avoid switch fallthru on
3383 BINOP_ASSIGN_MODIFY, so we can print += and such.
3384 * frame.h: Fix typo.
3385 * inflow.c (kill_command): After killing inferior, print our
3386 current frame in the core file, if we have one.
3387 (generic_mourn_inferior): When inferior dies, either select
3388 the current frame (in the new target, e.g. core file), or
3389 set both the current and selected frames to NULL.
3391 Changes from Peter Schauer.
3393 * infptrace.c: Avoid <sys/ptrace.h> on USG.
3395 * Make all file names fit in 14 characters (sigh and damn!):
3396 mv hp300hpux-xdep.c hp300ux-xdep.c
3397 mv symmetry-xdep.c symm-xdep.c

3404 mv remote-sa.m68k.shar rem-m68k.shar
3405 mv remote-multi.shar rem-multi.shar
3406 * Makefile.dist, README, config.gdb, convex-pinsn.c,
3407 tconfig/symmetry, tconfig/vxworks960, tconfig/vxworks68,
3408 xconfig/hp300hpux, xconfig/symmetry: Change names to shorter
3411 * command.c (user_info_1, user_info): New command for listing
3412 the user-defined commands.
3414 Wed Apr 3 15:00:26 1991 John Gilmore (gnu at cygint.cygnus.com)
3416 * dbxread.c (really_free_pendings): Clear file_symbols
3417 and global_symbols after freeing them; otherwise, running
3418 this function twice (if it appears twice on the cleanup
3419 chain), we try to free things twice.
3421 * dbxread.c (read_dbx_symtab): Calculate end_of_text_addr
3422 based on text_addr (the address of text in core), not on addr (the
3423 offset between text in the .o file and in core). This change
3424 is from Peter Schauer.
3426 * main.c: Define ALL_CLEANUPS as a cast of zero.
3427 (return_to_top_level): Use it.
3428 (main): Do all cleanups after each command run as part
3429 of the gdb startup sequence. Also do all cleanups before
3430 entering the command loop, and every time we exit the command
3431 loop and reenter. Before, the cleanups from the startup sequence
3432 were being left undone until the first error!
3433 (command_loop): Rename do_nothing cleanup to command_loop_marker
3434 so we can see it easily when examining the cleanup chain.
3435 (init_signals): Add another do_nothing for signal handling.
3436 (quit_command): Only try to kill target if it has execution.
3437 Problems in the target stack got us into a state where
3438 inferior_pid was nonzero but none of the targets had execution.
3439 In this state you couldn't exit gdb.
3441 * dbxread.c: Two changes from Peter Schauer.
3442 (echo_command): Fflush output after an echo command.
3443 (show_history): Pass all args to cmd_show_list.
3445 * utils.c (init_malloc): Call mtrace to turn on tracing
3446 if the environment variable MALLOC_TRACE is set to a file name.
3447 * mtrace.c: Add source file which provides a log of every malloc,
3448 free, and realloc to a trace file.
3449 * mtrace.awk: Add source file which analyzes the trace file.
3450 * Makefile.dist (GNU_MALLOC, MALLOCSRC): Add mtrace.{c,o,awk}.
3451 (VERSION): Roll to 3.94.3.
3453 * breakpoint.c (breakpoint_1): Add a space to "i watch" output.
3454 (check_duplicates): Don't bother with watchpoints.
3455 (set_raw_breakpoint): Comment about danger of this routine.
3456 (watch_command): Parse and eval all args before calling
3459 * solib.c (find_solib): Avoid error in referencing memory to
3460 see if any more shared libraries have been added. This is
3461 particularly useful if the target has terminated. Bug reported
3464 Changes from Peter Schauer <pesrem@regent.e-technik.tu-muenchen.de>
3465 in bringing up 3.94.2 on the Sun-3.
3467 * Makefile.dist: Include CFLAGS in rule for cplus-dem.o.
3468 * breakpoint.c (enable_breakpoint): Check for valid watchpoint
3469 expression (in scope) before reenabling watchpoint.
3470 * signame.c (init_sigs): Add missing declaration of i, fix
3471 sys_siglist declaration.
3472 * source.c (list_command): Fixed range computation to use
3474 * stack.c (backtrace_command): Do not allow command if target has
3475 no stack, print informative error message.
3476 * target.c (target_command): Do not write into command line
3477 because this fails if the target command is used in a user defined
3478 command. [This change was enhanced by gnu to support any-
3479 unique-prefix matching on target names.]
3480 * valops.c (value_struct_elt): Avoid infinite loop on an
3481 erroneous attempt to print the member of function (try p main.p).
3483 Mon Apr 1 17:05:45 1991 John Gilmore (gnu at cygint.cygnus.com)
3485 * expread.y (name_no_typename): Avoid reduce/reduce errors
3486 caused by ambiguity in handling NAME_OR_INT and NAME_OR_UINT.
3487 Since the GDB parser really doesn't use name_no_typename in a
3488 name-only context, the parser can't tell the diff between
3489 names and numbers here. Avoid allowing a name_no_typename
3490 to be a NAME_OR_*INT to resolve the conflict.
3492 Sun Mar 31 20:12:07 1991 John Gilmore (gnu at cygint.cygnus.com)
3494 Bugfixes from Mark Fox (markf@wrs.com) (test=testField.c):
3496 * valprint.c (val_print_fields): bitfield printing didn't handle
3497 byte order. Indirect through a few more fns to cope.
3499 * values.c (modify_field): also cope with byte order.
3501 Sat Mar 23 10:02:21 1991 John Gilmore (gnu at cygint.cygnus.com)
3503 Cleanup for release 3.94.2:
3505 * Makefile.dist: Pull REMOTE_OBS. Fix saber includes for BFD
3506 include files. Roll version to 3.94.2.
3508 * coffread.c (init_stringtab): Read length into unsigned char
3509 array before swapping; don't assume 32-bit longs.
3511 * target.c (target_info): Don't bother with get_sym_file, just use
3512 the symfile global variable.
3513 * symtab.h, symfile.c (get_sym_file): Delete it.
3515 * dbxread.c (dbx_symfile_init): Don't depend on long == 4 bytes.
3516 (define_symbol): Set symbol line number to 0 if not gcc-compiled.
3517 (read_type): Replace one more error() with complain().
3519 * mipsread.c (parse_partial_symbols): Replace printf with complain.
3521 * i960-tdep.c: Fix copyright attribution.
3523 * config.gdb: Quote all backquotes in doublequotes. You can
3524 quote me on that. BSD 4.4 shell found this one.
3526 * infptrace.c (throughout): The third argument to ptrace is an
3529 * infrun.c (wait_for_inferior): When program has terminated, we
3530 have to call target_terminal_ours before we pop that target off
3531 the stack (e.g. before a call to target_kill or
3532 target_mourn_inferior). This fixes problem where a program
3533 terminates, then GDB stops for (tty output) and you have to type
3534 "fg" to the shell to resume it. FIXME: This code for what to
3535 do after termination really should be in normal_stop instead.
3537 * gdbcore.h (read_memory_check): Change declaration; it changed
3540 * terminal.h: Include <sgtty.h> before <sys/ioctl.h>, since in BSD
3541 4.4 prereleases, this avoids a bug in their sgtty compatability
3543 * remote.c: Use terminal.h rather than hand-rolling the same.
3545 * signame.c, signame.h (psignal): Arg is unsigned, not int.
3546 * utils.c (strsave, strstr): Fix arg types.
3547 * valprint.c (val_print): lint
3549 MIPS symbol table support from Per Bothner:
3551 * symfile.c (symtab_fns): Remove initializer table that needs to
3552 be hacked for each new symbol file format supported.
3553 (add_symtab_fns): New function, chains symbol table
3554 handlers into the global list.
3555 (symfile_init): Search this list.
3556 * symfile.h: Add next pointer, declare add_symtab_fns.
3557 * coffread.c (_initialize_coffread): Call add_symtab_fns.
3558 * dbxread.c (_initialize_dbxread): Call add_symtab_fns.
3560 * mipsread.c (psymtab_to_symtab_1): return void instead of (struct
3561 symbol *). Thus, we no longer need the hack to trash
3562 pst->filename. Good, since that hack confused code in symfile.c!
3564 (reorder_symtabs, destroy_all_symtabs): Removed static
3565 all_symtabs, which was used to qsort symtabs in reorder_symtabs.
3566 Instead, the latter now uses a temporary array (stack-allocated
3567 from an obstack, and then freed).
3569 (parse_symbol): Added a hack to fix up BLOCK_{START,END} if they
3570 haven't been set in the outermost stBlock of a procedure. This was
3571 a problem with f77 binaries on Ultrix 4.?.
3573 (new_symtab, new_symbol, new_type): Continue changing code to use
3574 obstacks more and otherwise conform to dbxread internal style.
3575 Made the free_code of symtabs be free_linetable (as in dbxread)
3576 instead of free_contents. This implies memory leaks when reading
3577 a new symbol table, until the conversion is finished. Did change
3578 (struct symbol) and (struct type) to be allocated on the
3579 symbol_obstack. Blocks and blockvectors are among the things
3582 * mipsread.c (parse_partial_symbols, parse_fdr): It hasn't been
3583 tested much, but it solved one problem (reported by Meissner), and
3584 cleans up some other things. The problem happened when an
3585 included file contains actual code (functions) and not just
3586 definitions. The mips coff is a little inconvenient there, since
3587 it may cause a procedure to be mapped to the wrong psymtab.
3589 * mips-tdep.c (heuristic_proc_desc): Minor cleanup.
3590 * mips-xdep.c (fetch_core_registers): Minor cleanup. FIXME,
3591 this will need work for the new core paradigm.
3593 Opcode patches from the net:
3595 * mips-opcode.h: fix incorrect disassembly of the mfc1, cfc1, and
3596 ctc1 instructions. Also, the cvt.d.w and cvt.s.w instructions were
3597 missing altogether - they are added here. From Bruce Bauman.
3598 * mips-opcode.h: The low mask for C0 instructions was too small.
3599 From Garrett Lau. I modified the fix to check the entire 32-bit
3602 * ns32k-opcode.h: Fix opcodes for deiw and deid. From Bruce
3605 Thu Mar 21 12:56:46 1991 John Gilmore (gnu at cygint.cygnus.com)
3607 Roll in changes from Per Bothner (Tue, 25 Sep 90 11:11:04):
3609 * dbxread.c (read_type): Pointer subtraction (value_sub in
3610 valarith.c) sometimes failed because the types of the
3611 pointers being subtracted were not identical.
3612 These differed because dbxread.c was allocating pointer types
3613 using dbx_alloc_type+smash_to_pointer_type instead of
3614 lookup_pointer_type. I failed to find a justification for the
3615 former, so I changed it to use the latter. Similarly, I
3616 replaced smash_to_function_type by lookup_function_type,
3617 and smash_to_reference_type by lookup_reference_type.
3619 * mipsread.c (parse_symbol, upgrade_type, parse_procedure,
3620 _initialize_mipsread): corresponding changes.
3622 * symtab.c (smash_to_{pointer,reference,function}_type): eliminate.
3624 * source.c (mod_path): Do tilde_expand on each component of the path,
3625 rather than on the (list of) paths as a whole.
3626 (print_source_lines): Set first_line_listed in addition to
3627 current_source_symtab and current_source_line. If the source was
3628 not findable, after a "dir" command to fix the problem,
3629 a "list" would get the wrong lines.
3631 While I was there... (gnu):
3633 * dbxread.c (read_type): Change error to complaint.
3635 Thu Mar 21 12:56:46 1991 John Gilmore (gnu at cygint.cygnus.com)
3637 First attempt at detailed understanding of symbol table memory alloc.
3639 * dbxread.c (dbx_symfile_read): Free our string table if we
3640 aren't the mainline. Free the "info" struct since we're done with
3642 (init_psymbol_list): Free any previously allocated psymbol lists.
3643 (): FIXME: Should realloc-down the psymbol lists when done reading
3644 the main symbol file?
3646 * symmisc.c (free_symtab): Free fullname field too.
3648 * xm-hp300hpux.h (USG): #undef then #define so Makefile can -D.
3649 (REGISTER_ADDR): Make result type unsigned int.
3651 * xconfig/{i386*,hp300hpux,altosgas,altos}: All config files that
3652 define REGEX must also define REGEX1 (its dependency).
3654 Tue Mar 19 21:28:57 1991 John Gilmore (gnu at cygint.cygnus.com)
3656 * tconfig/i960: No longer works, points you at vxworks960 or
3659 * xgdb.c, XGDB-README: Remove file. Users can get the much
3661 * Makefile.dist: Remove all trace of xgdb.
3663 * breakpoint.c (breakpoint_1): Pass demangle arg to
3664 print_address_symbolic.
3665 (clear_breakpoints): Remove unused function.
3666 (breakpoint_re_set_one): Guts of breakpoint_re_set.
3667 (breakpoint_re_set): Use catch_errors to do them all anyway.
3669 * gdb-int.texinfo (Host versus Target): Add section on what is
3670 a "host" feature versus what is a "target" feature.
3672 * infcmd.c (path_command, path_info): Handle the PATH variable
3673 (object search path) as conveniently as the source search path.
3674 * environ.c (set_in_environ): Set some vars in GDB's environment,
3675 in addition to the child's. PATH, G960BASE, G960BIN for starters.
3676 * source.c (mod_path): New function, from guts of
3677 directory_command, modifies a path. Used by path_command.
3678 (directory_command): Call it.
3679 * defs.h (strsave): Declare.
3681 * utils.c (sevenbit_strings): Add new printing option.
3682 (printchar): Use it.
3683 (strsave): Provide this handy helper routine.
3684 (set_width_command): Rename set_screen_width_command.
3685 (_initialize_utils): "set screen-width" => "set width";
3686 "set screen-height" => "set height"; add sevenbit-strings.
3688 * infcmd.c (do_registers_info): Print floating point registers
3689 in raw hex as well as float format, regardless of whether it is
3690 a "virtual" convertible register.
3691 * tm-sparc.h (PRINT_REGISTER_HOOK): Print every pair of float
3692 regs as a double, just in case it's being used that way.
3693 * values.c (unpack_long): Comment on array/function coercion.
3694 (unpack_double): Argument is in target byte order now. For
3695 integer arguments, just call unpack_long and float the result.
3696 * m68k-tdep.c: include defs.h for "const" handling.
3697 * remote-nindy.c: Use ieee-float stuff.
3698 (nindy_fetch_registers): Unpack double regs to host double, then
3700 (nindy_store_registers): Pack extendeds to host double, flip
3701 around by misusing unpack_double, send as target double.
3703 * tm-vxworks68.h (FRAME_CHAIN): Handle current frame pointer of
3704 zero, as when stopped at the first instruction of a process.
3706 * blockframe.c: Fix filename in comment (param.h => tm.h).
3707 * sparc-tdep.c (skip_prologue): More explicit nudging comments.
3708 * tm-68k.h: Fix typos.
3710 Fri Mar 15 01:09:34 1991 John Gilmore (gnu at cygint.cygnus.com)
3712 Changes from a bringup on the DEC Vax under Ultrix 4.0.
3714 * coredep.c (fetch_core_registers): Pass end-address of register
3715 section to register_addr as expected. Don't call supply_register
3716 if we'd just pass it garbage.
3718 * dbxread.c (read_dbx_symtab): Skip N_NSYMS on Ultrix.
3720 * exec.c (xfer_memory): Use boolean xfer_fn result, not int.
3722 * target.c (push_target, target_info): Cast enums to int for < or
3725 * stack.c (print_frame_info): Identify source file & line
3726 even if we can't print it.
3728 * xm-vax.h (MISSING_VPRINTF): No longer missing in Ultrix V4.0.
3730 Sat Mar 9 10:08:20 1991 John Gilmore (gnu at cygint.cygnus.com)
3732 Clean up IEEE floating point support.
3734 * ieee-float.h: New file.
3735 * ieee-float.c: Write real routines to convert between host
3736 doubles and various target IEEE extendeds.
3737 * m68k-xdep.c: Eliminate assembler code for extended floats.
3738 * xconfig/{3b1,altos,altosgas,hp300bsd,isi,news,news1000,sun2os3,
3739 sun2os4,sun3,sun3os3,sun3os4}: Eliminate use of m68k-xdep.o.
3740 * tm-i960.h, tm-68k.h (REGISTER_CONVERT_TO_VIRTUAL,
3741 REGISTER_CONVERT_TO_RAW): Use ieee_extended_to_double and
3742 double_to_ieee_extended.
3743 * i960-tdep.c: Define ext_format_i960.
3744 * m68k-tdep.c: Define ext_format_68881.
3745 * sparc-tdep.c: Define ext_format_sparc, though unused.
3746 * Makefile.dist (HFILES): Add ieee-float.h.
3747 * inftarg.c: #include "ieee-float.h" for the REGISTER_CONVERT
3750 Obsolete the "coffstrip" program in favor of using BFD's strip.
3752 * nindy-share/coffstrip.c: Remove file.
3753 * nindy-share/nindy.c (coffstrip): Routine to run bfd_strip.
3754 * Makefile.dist: Remove references to nindy-share/coffstrip.c.
3755 * tconfig/nindy960: Remove reference to coffstrip.o.
3757 * Makefile.dist: Roll version number to 3.94.1 (not yet final).
3759 Wed Mar 6 09:56:45 1991 John Gilmore (gnu at cygint.cygnus.com)
3761 * symfile.h: Add symfile_bfd, common between dbxread and coffread.
3762 * dbxread.c: Remove static symfile_bfd.
3763 * infcmd.c (do_registers_info): Add PRINT_REGISTER_HOOK, though
3765 * inftarg.c (child_detach): Pop the child_ops vector if the
3766 detach is successful.
3767 * remote-nindy.c (nindy_create_inferior): Don't push a new
3768 nindy_ops since nindy uses the same one for execution and memory
3770 * core.c (core_ops): Use child_attach and child_create_inferior
3771 rather than default attach and create_inferior functions.
3773 Handle floating point registers in core files.
3775 * sparc-xdep.c (fetch_core_registers): Rewrite for float support.
3776 * sun3-xdep.c (fetch_core_registers): Rewrite for float support.
3777 This version untested since BFD doesn't yet support sun3 core
3779 * hp300hpux-xdep.c: Rewrite fetch_core_registers to new calling
3780 conventions. Fix comments and style. This version has not
3781 been compiled yet, since we have no HP inhouse.
3782 * core.c (get_core_registers): Look for two sections, ".reg"
3783 and ".reg2", and pass both to fetch_core_registers sequentially.
3785 Revise directory path yet again.
3787 * source.c (forget_cached_source_info): Not static any more.
3788 (init_source_path): New default source path is "$cdir:$cwd".
3789 (dir_command): Handle variable arguments ($cdir, $cwd).
3790 (source_info): Print "Compilation directory" rather than
3791 "Originally compiled in" to remind people of $cdir.
3792 (openp): If the path contains $cwd, use current directory.
3793 (open_source_file): If compilation directory is known, replace
3794 first $cdir in path with the compilation directory.
3795 (print_source_lines): Even if we can't print the lines, set the
3796 current symtab and line for future commands like "info source" or
3797 "breakpoint". Also, error message now contains the file name,
3798 line number, and file access error message.
3799 (_initialize_source): Fix help text to describe changes.
3800 * main.c (cd_command): Forget cached source info when we chdir.
3801 * utils.c (strstr): Add simple implementation.
3803 Tue Mar 5 01:41:40 1991 John Gilmore (gnu at fowanton.cygnus.com)
3805 * coffread.c (read_one_sym, init_linetable, init_stringtab):
3806 Byte-swap COFF symbol tables if necessary when reading them in.
3807 Use complain() to replace error message in one spot. Needs
3808 corresponding change in bfd/coff-code.h to make some symbol
3809 swapping routines non-static.
3811 Mon Mar 4 00:53:40 1991 John Gilmore (gnu at cygint.cygnus.com)
3813 Merge changes from Eirik Fuller, for UTek.
3815 * defs.h (errno): Add declaration.
3816 * altos-xdep.c, arm-xdep.c, convex-xdep.c, gould-xdep.c,
3817 hp300hpux-xdep.c, infrun.c, inflow.c, infptrace.c, i386-tdep.c,
3818 i386-xdep.c, pyr-xdep.c, mips-xdep.c, remote-eb.c, remote-nindy.c,
3819 remote-vx.c, source.c, standalone.c, stuff.c, sun386-xdep.c,
3820 symmetry-tdep.c, symmetry-xdep.c, umax-xdep.c, utils.c: Eliminate
3821 declarations of errno.
3823 * remote-eb.c: Define B19200 and B38400 as EXTA and EXTB.
3825 * remote-vx.c: Include <sys/time.h> for UTek; Sun gets it via
3826 <rpc/rpc.h> and <rpc/types.h>.
3828 Sat Mar 2 15:47:55 1991 John Gilmore (gnu at cygint.cygnus.com)
3830 * i960-tdep.c (examine_prologue): Add new argument limit,
3831 which stops the scan at the end of the prologue, or at the PC.
3832 This fixes a problem where it walks down into the code for the
3833 user's statements if that code looks like function prologues.
3834 Mark Fox and I have been bouncing this code back and forth, making
3835 small changes to it. Callers changed to match.
3837 Tue Feb 26 01:47:07 1991 Cygnus John Gilmore (cygnus at yuba)
3839 Cleanup for gdb-3.94 release final:
3841 * Makefile.dist: Remove remote-vx.c, remote-nindy.c, and all
3842 the .c files from vx-share and nindy-share, from the various
3843 macros, since they are not found via ALLDEPFILES.
3844 (SFILES): Add tm-i960.h.
3845 (alldeps.mak rule): Break out ALLDEPFILES_MAINDIR and
3846 ALLDEPFILES_SUBDIR. List all the nindy and vxworks subdir files
3848 (TAGFILES_MAINDIR): Change ALLDEPFILES to ALLDEPFILES_MAINDIR.
3849 (gdb.tar.Z): Use ALLDEPFILES_SUBDIR as well as SFILES_SUBDIR.
3851 Mon Feb 25 16:02:35 1991 Cygnus John Gilmore (cygnus at oldman)
3853 * am29k-tdep.c: Add contribution line.
3854 (examine_prologue): Cache information about function prologues in
3855 the misc-function-vector to avoid lots of references over the
3856 serial line while examining instructions.
3858 * core.c (core_close): New function made from cleanup_core.
3860 * core.c, exec.c, inftarg.c, remote-eb.c, remote-nindy.c,
3861 remote-vx.c, remote.c, target.c, target.h,
3862 Update target_ops vector to add attach, close, and load entries.
3863 Use add_syms_addr_command, not add_file_addr_command, for
3864 add_file. Break out close routine from existing code.
3866 * dbxread.c (really_free_pendings): Don't free pending_blocks;
3867 they are in an obstack.
3868 (read_dbx_symtab): Relocate end_of_text_addr in the psymtab.
3870 (define_symbol): Add symbol type parameter; change callers;
3871 pass type parameter to DBX_PARM_SYMBOL_CLASS macro to allow
3872 it to influence the symbol class on the i960.
3873 (define_symbol): Swap LOC_CONST's into target byte order.
3875 * exec.c (exec_close): New function.
3876 (exec_file_command): Call it.
3878 * findvar.c (read_relative_register_raw_bytes): Doc byte order,
3879 Fix byte order of frame pointer.
3880 (read_var_value): Result of 0 if var's value can't be found,
3881 e.g. missing FRAME_ARGS_ADDRESS. Byte-swap LOC_CONST and
3882 LOC_LABEL values to target order. Add LOC_LOCAL_ARG.
3883 (locate_var_value): Use read_var_value and use its lazy address
3884 as the location of the var's value. Lint.
3886 * i960-pinsn.c (next_insn): Add routine from vxgdb for scanning
3889 * i960-tdep.c (arg_address, i960_frame_find_saved_regs): Remove
3890 obsolete Intel versions in favor of vxgdb versions.
3891 (check_host, byteswap, byteswap_val, reorder_val): Eliminate
3892 code dealing with byte order of values, which Intel did in host byte
3893 order rather than gdb-4's target byte order.
3894 (i960_frame_chain_valid): Move to nindy-tdep.c.
3895 (examine_prologue, skip_prologue, frame_find_saved_regs,
3896 frame_args_address, leafproc_return, saved_pc_after_call,
3897 pop_frame): Add vxgdb versions from Mark Fox.
3898 (examine_prologue, frame_struct_result_address): Add code
3899 to deal with the saved value of G13 (struct return address
3901 (frame_args_address): Modify Mark's version to prefer the
3902 saved value over the current value in the topmost frame.
3903 Cache result in the frame info to avoid performance hair in
3905 (print_fault): Add gdb960 code for printing faults.
3906 (_initialize_i960): Actually call check_host.
3908 * ieee-float.c (ieee_extended_to_double, ieee_double_to_extended):
3909 add stub routines. FIXME, these currently just return zero!
3911 * infcmd.c (program_info): Use PRINT_RANDOM_SIGNAL.
3912 (attach_command): Call target_attach, not target_open, now.
3914 * infrun.c (normal_stop): Make global, not static, for vx_attach.
3915 (child_attach): Rename from child_open.
3916 (wait_for_inferior): Use PRINT_RANDOM_SIGNAL. If stop_pc is zero,
3917 don't confuse it with a zero step_resume_break_address.
3919 * inftarg.c (child_detach): Eliminate inferior_pid test.
3920 (child_files_info): Clean up message a bit.
3921 (child_ops): Use child_attach, not child_open, to attach.
3923 * mem-break.c: #ifdef out the whole file if BREAKPOINT is not
3924 set (e.g. on VxWorks or NINDY). Move read_memory_nobpt from
3925 findvar.c to here, since it depends on the contents of the
3926 shadow_contents of breakpoints, but keep if #if 0 since it is
3929 * nindy-tdep.c: New file, contains nindy_frame_chain_valid, moved
3932 * printcmd.c (address_info): Handle LOC_LOCAL_ARG. Lint.
3933 (ptype_command, display_command): Eliminate have_inferior_p and
3934 have_core_file_p in favor of target_has_stack or
3935 target_has_execution.
3936 (print_frame_args): Handle LOC_LOCAL_ARG. Eliminate duplicate
3937 code for actually finding the values of arguments, though we still
3938 keep track of the maximum stack offset for use in printing unnamed
3939 arguments. Handle missing FRAME_ARGS_ADDRESS.
3941 * remote-nindy.c (i960_print_fault): Move to i960-tdep.c.
3942 (struct nindy_regs): Define registers passed to/from nindy.
3943 (nindy_fetch_registers, nindy_store-registers): Translate between
3944 nindy and GDB formats for the registers.
3945 (dcache_init): Statically allocate the cache, since it was being
3946 allocated by a malloc that was never freed anyway.
3947 (nindy_create_inferior): Error, not core dump, if no exec file.
3948 (nindy_before_main_loop): Use target_load, not target_add_file.
3950 * remote-vx.c (net_load): Specify large timeout for load
3951 requests. Allow user to break out with INTERRUPT.
3952 (net_break): Remove useless code, clean up. Change callers.
3953 (parse-args, skip_white_space, find_white_space): Clean up arg
3954 parsing to cope with quoted strings.
3955 (net_wait, net_quit): Never call error, just return status.
3956 (vx_read_register, vx_write_register): Cleanup status checking.
3957 #ifdef the code based on which CPU we are using (960 or 68k),
3958 FIXME, this should be completely general but it isn't yet.
3959 (vx_xfer_memory, vx_resume): Cleanup status checking.
3960 (vx_run_files_info): Improve message.
3961 (vx_load_command): Renamed from vx_add_file_command. Allow load
3963 (net_ptrace): Remove unused routine.
3964 (vx_wait): Adopt code from vxgdb960 to cope with broken
3965 connections to target machine and prompt to disconnect. Remove
3966 debug printouts. Map some EVENT_'s to SIGnals.
3967 (add_symbol_stub, vx_open): Print names of object files we found,
3968 and "ok" if we read their symbols OK. Clarify output in general.
3969 (vx_attach, vx_detach, vx_kill): Add these commands.
3970 (vx_convert_from_virtual, vx_convert_to_virtual): Simplify.
3971 (vx_run_ops): Turn off all_mem, to avoid spurious msg in the
3972 "info files" output, and create_inferior, since we already have
3975 * stack.c (frame_info): Replace Frame_unknown with 0.
3976 (print_frame_arg_vars): Handle LOC_LOCAL_ARG.
3977 (return_command): Pop until the PC matches as well as the FP,
3978 so it works even if the FP is shared with another function,
3979 as in "frameless" or "leaf" procedures.
3981 * symfile.c (load_command): renamed from add_file_target_command.
3982 (add_syms_addr_command): renamed from add_file_addr_command.
3983 (add_syms_command): Stub to call target_add_syms.
3984 (_initialize_symfile): Change command names and descriptions,
3985 add-file => add-syms, and load from alias to its own command.
3987 * target.c (kill_or_be_killed, maybe_kill_then_attach,
3988 maybe_kill_then_create_inferior): Default for attempts to start
3989 a process, if one is already running, is to ask about killing
3990 it and retry if yes.
3991 (upstack_create_inferior): #if-0 it, strata obsolete it.
3992 (push_target, unpush_target, pop_target): to_close() a target
3993 before unstacking it.
3994 (target_info): Renamed from target_files_info.
3995 (_initialize_targets): Rename "i files" as "i target", accessible
3998 * target.h: Improve comments about the target_ vectored routines.
4000 * tm-i960.h: Remove NINDY-specific stuff to tm-nindy960.h.
4001 Convert commenting style to standard GNU style.
4002 (DBX_PARM_SYMBOL_CLASS): allow LOC_LOCAL_ARG's to be recognized.
4003 (SKIP_PROLOGUE): No longer a no-op.
4004 (SAVED_PC_AFTER_CALL): Now handles leaf procedures.
4005 (*_REGNUM): Sort register numbers.
4006 (REGISTER_BYTES, REGISTER_BYTE, REGISTER_RAW_SIZE,
4007 MAX_REGISTER_RAW_SIZE, REGISTER_CONVERTIBLE,
4008 REGISTER_CONVERT_TO_VIRTUAL, REGISTER_CONVERT_TO_RAW): Float regs
4009 are now 10 byte extendeds, not 8 byte doubles.
4010 (FRAME_CHAIN_VALID): Make this config-dependent, since it differs
4011 for nindy versus vxworks targets. FIXME, this should possibly go
4012 in the target vector.
4013 (EXTRA_FRAME_INFO, INIT_EXTRA_FRAME_INFO): Cache both
4014 frame_saved_regs and arg pointer with each frame.
4015 (FRAMELESS_FUNCTION_INVOCATION): New leafproc support.
4016 (FRAME_ARGS_ADDRESS): Use cached result.
4017 (FRAME_ARGS_ADDRESS_CORRECT): New, avoids g14 guessing.
4018 (FRAME_FIND_SAVED_REGS): Change arg to subsidiary fn.
4019 (PRINT_RAMDON_SIGNAL): Call print_fault.
4020 (POP_FRAME): Now works.
4022 * tm-nindy960.h: Break this off tm-i960.h. NINDY-specific
4023 option parsing and startup; STACK_END_ADDR, FRAME_CHAIN_VALID,
4024 BREAKPOINT, and DECR_PC_AFTER_BREAK are here.
4025 (ADDITIONAL_OPTION_HANDLER): use target_load, not
4028 * tm-vxworks960.h: Break this off tm-i960.h. VxGDB specific
4029 startup; DECR_PC_AFTER_BREAK, and FRAME_CHAIN_VALID are here.
4031 * valarith.c (value_subscripted_rvalue): Avoid handling
4032 floats and doubles specially; it gave alignment errors. Lint.
4034 * valops.c (value_of_variable, value_of_this): Error if unknown
4037 * valprint.c (print_floating): Bcopy rather than pointer-deref,
4038 to avoid alignment problems.
4039 (value_print): Handle unknown value address.
4040 (cplus_val_print): Two args are ignored; remove them. Change caller.
4041 (val_print): Use unpack_long rather than pointer-deref.
4044 (unpack_long, unpack_double): Use bcopy rather than pointer-deref
4045 to avoid alignment problems.
4046 (value_being_returned): Error if return value unknown.
4047 (set_return_value): Add bogosity warning, FIXME. *
4049 * TODO: A woman's work is never done.
4051 * Makefile.dist: Distribute REMOTE_OBS into tconfig files.
4052 Separate INCLUDE_CFLAGS for use with lint. Add LINTFILES.
4053 Add ieee-float.o to OBS.
4054 * tconfig/{nindy960,vxworks68,vxworks960}: Include the desired
4055 REMOTE_OBS remote-interface files in the TDEPFILES and TM_FILE.
4056 * tconfig/i960: FIXME. Half-merge, produce warning if config'd.
4058 Changes to generalize the VxWorks RPC protocol slightly, to handle
4059 i960 as well as 68000.
4061 * vx-share/dbgRpcLib.h (VX_SOURCE_STEP): Add.
4062 * vx-share/reg.h: Produce i960 regs #ifdef I80960
4063 * vx-share/xdr_ptrace.c: Skip FPA registers if 960.
4064 * vx-share/xdr_rdb.h: Add SOURCE_STEP struct and xdr decl.
4065 * vx-share/xdr_rdb.c: Add xdr_SOURCE_STEP routine.
4066 * vx-share/xdr_regs.c: Add xdr_regs, xdr_fp_status, xdr_ext_fp
4067 for i960. Change xdr_vectors to xdr_opaques for 68k registers,
4068 so they will move in target byte order rather than network
4069 byte order (happens to be the same).
4071 Mon Feb 25 03:41:44 1991 John Gilmore (gnu at cygint.cygnus.com)
4073 * tm-convex.h (END_OF_TEXT_DEFAULT): Remove #if 0'd block.
4075 Sun Feb 24 00:55:53 1991 John Gilmore (gnu at cygint.cygnus.com)
4078 Add contribution lines to various files, showing where they
4081 * breakpoint.c (break_insn, check_break_insn_size,
4082 read_memory_nobpt): Remove to mem-break.c.
4084 * xm-*.h, param-no-tm.h, tm-29k.h, valprint.c: Change BYTE_ORDER to
4087 * tm-29k.h (STAB_REG_TO_REGNUM): Warn user if symbol table
4088 entry has bad register number. This change is not
4089 tested in this release, FIXME.
4091 * frame.h: Eliminate Frame_unknown in favor of a simple zero.
4094 * value.h: Force value's contents field to be aligned to hold
4095 at least a double or a long long (if supported). This avoids
4096 doing bcopy's in and out of the contents field.
4098 (step_1): Avoid coredump under obscure circumstances when we
4101 * symtab.h (misc_info): Add field to misc function vector for
4102 any kind of cached information the target code desires. AMD
4103 29000 uses this to avoid repeating examine_function_prologue's.
4105 * coffread.c: Lint. Remove static symfile, read_section_header.
4106 core.c (have_core_file_p): Lint: remove.
4107 expprint.c (print_subexp): Lint.
4108 infptrace.c, valops.c, valprint.c: lint.
4110 Roll in changes from vxgdb-5.0.1:
4112 * symtab.h: Comment byte order of each address class. Add
4113 LOC_LOCAL_ARG for frame-relative args (960).
4114 expread.y: Use LOC_LOCAL_ARG where LOC_ARG is used.
4115 symtab.c, symmisc.c: ditto.
4117 * infrun.c (init_wait_for_inferior): Clear stop_signal.
4119 * remote.c (remote_resume): Error if resume with a signal.
4121 * symfile.c (prim_record_misc_function): Clear misc_info.
4122 (fill_in_vptr_fieldno): Check stub type of arg.
4124 * valops.c (value_cast): Avoid looking up names of types whose
4125 name we don't know, to prevent coredump. Sun CC produces typedef
4126 rtx and the name of *rtx is zero...
4128 Mon Feb 18 21:16:25 1991 John Gilmore (gnu at cygint.cygnus.com)
4130 Roll in changes from final AMD 29000 port (Tiemann).
4132 tconfig/am29k: Add COFF_ENCAPSULATE and TARGET=TARGET_AM29K
4133 for ../include/a.out.encap.h. This might not work now that BFD
4134 is separately compiled. Instead, BFD support for encap will have
4135 to translate machine type 29k into the right COFF_MAGIC.
4137 * infcmd.c: Remove references to inferior_pid that aren't used
4138 in actual ptrace calls; use target_has_execution, etc.
4139 (have_inferior_p): Remove function.
4140 (program_info): Print target info rather than "process number";
4141 avoid gratuitous messages unless from_tty.
4142 (run_stack_dummy, finish_command): Set proceed_to_finish.
4143 infrun.c: Remove inferior_pid refs. Decl & init proceed_to_finish.
4144 main.c: Lint. Lose have_inferior_p().
4145 inferior.h (have_inferior_p): Remove, lint.
4146 (proceed_to_finish): Add flag to ask that all regs be saved
4147 by normal_stop, for the few commands that need it, speeding up
4148 serial I/O. Add comments to stop_registers.
4150 * remote-eb.c: Remove newline from breakpoint message we grep
4151 for. Never time out when running the user program.
4155 Wed Feb 13 15:34:40 1991 John Gilmore (gnu at cygint.cygnus.com)
4157 Roll in changes from vxgdb-5.0.1:
4159 * dbxread.c (read_dbx_symtab): If we encounter a "FORTRAN COMMON"
4160 symbol in its raw form, we are processing an unlinked ".o" file.
4161 See if the target environment has assigned it an address, using
4162 target_lookup_symbol (VxWorks does), and enter it into the symtab
4165 * tm-vxworks.h (FRAME_CHAIN, FRAME_CHAIN_VALID): Override usual
4166 68k versions for a simpler version that assumes zero FP at bottom.
4167 Fixes bug of truncated stack reports.
4169 * target.h (target_lookup_symbol): Define this routine's args
4170 and result, finally.
4172 * target.c (nosymbol): Default routine for target_lookup_symbol.
4173 (target_default): Default lookup_symbol and call_function too.
4174 (files_info): Only print has_all_memory warning if a non-dummy
4177 * remote-vx.c (vx_read_register, vx_convert_to_virtual,
4178 vx_convert_from_virtual): If target does not have floating point,
4179 zero register "values", and avoid doing cross-net conversions.
4180 (vx_lookup_symbol): Rename net_lookup_symbol, add to vectors.
4181 (vx_open): Rearrange code that attaches to target and reads
4182 symbols for all loaded modules, to work if some of the modules
4183 are not accessible. Add symbol_stub() and add_symbol_stub()
4184 as callbacks from catch_errors(). Allow connect attempt to be
4185 interrupted painlessly with ^C (FIXME, there are still some bugs
4186 if the interrupt happens during symbol reading.). Print
4187 final message with puts_filtered, since symbol messages are
4192 * main.c (catch_errors): Only print errstring if non-null.
4193 (command_loop): Avoid an ioctl per command to test ISATTY.
4195 * remote-vx.c (net_load): make static; avoid sophomoric msg.
4196 (vx_xfer_memory): Return correct result!
4197 (vx_files_info): Indicate whether target has float or not.
4198 (vx_lookup_symbol): Complain, not error, if target gone.
4199 (vx_open): Print "Connected" msg before disabling immediate-quit.
4200 [FIXME: lookup_symbol and vx_open changes need testing.]
4202 target.c, remote-eb.c, inftarg.c, am29k-opcode.h, target.h,
4203 tm-29k.h, tmm-vxworks68.h, symfile.c, gdb-int.texinfo: Add
4204 contributor lines and update copyrights to 1991.
4206 Changes from an attempted H-PUX host port:
4208 * infptrace.c (PT_ATTACH, PT_DETACH): Handle HP/UX, which
4209 defines PT_ATTACH and PT_DETACH but not PT_KILL.
4210 * remote-eb.c (eb_open): Misplaced endif kills sysv H/PUX.
4211 * remote-vx.c: include <sys/time.h> for HPUX.
4212 * hp300hpux-xdep.c (fetch_core_registers): Rewrite old
4213 "core_file_command" routine to BFD regime. May not work yet.
4215 Attempted port of "gdb-3.4 Van Jacobson xgdb" to modern gdb.
4217 * xgdb.c: Replace X10 version with some VJ version.
4218 (FIXME: Its copyright assignment is not on record.)
4219 * xgdb.c: Update include files to X11R4 (Xaw crud).
4220 (xgdb_display_source, create_text_widget): fix call to
4221 get_filename_and_charpos. Rewack source window stuff for X11R4
4222 (gleaned from include files, and "nm's" of binary libraries, since
4223 I had no doc available).
4224 (append_selection, append_selection_word): Disable with FIXME
4225 since R4 changed interface here.
4226 (create_buttons): Add back the old set of buttons.
4227 (xgdb_create_window): Fix call to XtInitialize (&argc not argc).
4229 * Makefile.dist (xgdb, xgdb-init.c): Update for X11R4 on Suns.
4230 Roll VERSION to 3.94 (not yet final though).
4232 Sat Feb 9 09:46:25 1991 John Gilmore (gnu at cygint.cygnus.com)
4234 * obstack.h (obstack_ptr_grow, obstack_ptr_grow_fast,
4235 obstack_int_grow, obstack_int_grow_fast): Eliminate
4236 cast on left of assignment, which gives MIPS cc fits and is
4239 * sparc-pinsn.c (print_insn): Eliminate 'set' test, subsumed by
4240 F_ALIAS. Use printf, not fprintf, when not passing a file
4242 (compare_opcodes): Check that identical instructions have
4243 identical opcodes, complain otherwise.
4245 * sparc-opcode.h (st %fsr): Fix opcode "lose" mask. This
4246 was reported by Roland McGrath.
4247 (unimp): Only match if exactly zero instruction. (Roland)
4248 (branches and traps): Generate all variations of these
4249 instructions with macros, based on a single call that defines
4250 each condition name and its binary representation.
4251 (set): Turn on alias bit, to avoid test in sparc-pinsn.c.
4253 * valprint.c (val_print_fields): Take, and use, format parameter.
4254 This means that "p/x struct" again prints the elements in the
4255 desired format. Changed callers.
4257 * stack.c (frame_info): Use filtered output, and indicate wrap
4258 points. Remove kludgy formatting designed to avoid line wrap.
4260 * utils.c (wrap_here): If the line is already full (because
4261 we had printed a long indent or long wrapped string), do an
4262 immediate newline-and-indent.
4264 * m68k-pinsn.c (print_insn_arg): Bugfix from
4265 ntmtv!thompson@ames.arc.nasa.gov (Mike Thompson): 'bkpt #0'
4266 instruction is incorrectly disassembled as bkpt #8.
4268 * dbxread.c (end_psymtab): Bugfix from Peter Schauer
4269 <pesrem@regent.e-technik.tu-muenchen.de>: If you want to set a
4270 breakpoint in a *.y file gdb will say Reading in symbols for *.y...
4271 and then will dump core (sometimes). I traced it back to an
4272 uninitialized symfile_name in psymtab_to_symtab.
4273 (const_vol_complaint): Add quotes to message.
4274 (define_symbol): Only believe line number if gcc_compiled.
4275 Avoid allocating symbol if we will not return it.
4277 Add target strata support so that newly established targets go
4278 into their right place in the target stack (e.g. a new exec file
4279 doesn't wipe out the ability to access the running process).
4281 * target.h, core.c, exec.c, inftarg.c, remote-eb.c,
4282 remote-nindy.c, remote-vx.c, remote.c, target.c: Add to_stratum
4283 and initialize it properly in all the targets.
4285 * target.h: Document strata. Change return type of push_target.
4287 * target.c (nomemory): new function for dummy memory access.
4288 (tcomplain): Rename complain, now also used in symfile.c.
4289 (push_target): Push targets within strata. New return value shows
4290 whether new target is on top of stack or not. Always keep dummy
4292 (target_files_info): Ignore dummy target.
4294 * core.c (core_open): Warn user, and skip accessing file, if the
4295 core target is not the topmost target in the stack.
4296 * remote-nindy.c (nindy_create_inferior): Avoid unpush_target, now
4299 * remote-vx.c: Remove vx_prepare_to_store from vxworks memory
4300 target_ops, it doesn't belong there since we have no regs there.
4301 Change name of target from machine => memory to clarify.
4303 Thu Feb 7 16:32:09 1991 John Gilmore (gnu at spiff.cygnus.com)
4305 * Freeze version 3.93 for release.
4307 * Makefile.dist: Handle vx-share and nindy-share subdirs
4308 properly when building gdb.tar.Z.
4310 * symtab.c: lint; add no_symtab_msg to consolidate the messages
4311 printed in various places, so I could change just one copy.
4313 * dbxread.c, coffread.c: Change references to bfd->iostream
4314 to cast to FILE *, now that BFD avoids needing types defined
4315 in other header files.
4317 Tue Feb 5 21:39:35 1991 John Gilmore (gnu at cygint.cygnus.com)
4319 * command.c, dbxread.c, expprint.c, infcmd.c, infptrace.c,
4320 infrun.c, printcmd.c, remote-nindy.c, source.c, sparc-tdep.c,
4321 sparc-xdep.c, symfile.h, symmisc.c, utils.c, valprint.c: Lint
4322 (actually gcc -Wall).
4324 * dbxread.c: Remove first_global_sym, last_global_sym, since
4325 they are never referenced.
4327 * defs.h (baud_rate): Declare.
4328 main.c: Define it, and add the -b option to set it.
4330 * gdb-int.texinfo: Add text on how to define a new host or target
4331 architecture, prompted by Per Bothner's questions about MIPS
4334 * gdb.texinfo: Document "complaints". Change doc of -q since
4335 gdb no longer prints the copyright and blurb if you specify a file
4336 name to be debugged (just like Emacs). Add doc for Nindy-specific
4337 command line flags for specifying target serial port and such.
4338 Update copyright to 1991.
4340 * gdbcore.h: Remove a large mass of now-useless crud, since BFD
4341 has taken over for us the job of ripping up executable files. The
4342 crud caused Per Bothner's port to not compile.
4344 * infrun.c (normal_stop): Avoid printing "Program exited
4345 normally" if we are in batch mode. This allows a GDB which
4346 executes a program on a target system, to behave like a Unix
4347 command (input from stdin, output to stdout, no extraneous
4350 * main.c (main): Allow additional machine-dependent command line
4351 options to be specified with the ADDITIONAL_OPTIONS,
4352 ADDITIONAL_OPTION_CASES, ADDITIONAL_OPTION_HELP, and
4353 ADDITIONAL_OPTION_HANDLER macros. Also allow machine-dependent
4354 processing to occur just before the main loop with
4355 BEFORE_MAIN_LOOP_HOOK.
4356 (main): If a "core file" argument is specified, and it is not a
4357 core file, try it as a process ID to attach.
4358 (symbol_completion_function): Attempt to cope with
4359 "show screen-" TAB, not very successfully. This needs more work,
4361 (batch_file): New function, returns whether we are reading
4362 commands from an interactive tty on stdin, or from somewhere else.
4363 Called by normal_stop since it doesn't get from_tty passed down
4364 to it like many commands do.
4366 * remote-nindy.c: Handle command line options for nindy
4368 (nindy_before_main_loop): Prompt user for tty name if they
4369 don't specify it before getting to the interactive command loop.
4371 * tm-i960.c: Add ADDITIONAL_OPTIONS, etc, to handle -O, -brk,
4372 and -r command line options. Also add hook before main loop
4373 to make it easy to specify a tty.
4375 * TODO: More things to do, one done.
4377 Mon Feb 4 23:57:39 1991 John Gilmore and Mike Tiemann (at cygint.cygnus.com)
4379 * dbxread.c: Make complaint() calls pass pointer, not struct.
4380 Add complaints about badly formatted C++ type information
4381 (const/volatile indicator, and parse errors resulting in
4382 error_type). Fix C++ virtual member fn comment.
4383 (read_struct_type): Avoid bumping pointer if we got a parse
4384 error; this prevents our walking beyond the end of a string.
4385 Terminate loop on null char as well as semicolon.
4386 (process_one_symbol): Fix the LBRAC fix so that it uses the
4387 last previous SLINE, FUN, or SO record's PC address. C++ debug
4388 symbols did not have SLINE records in a useful order compared
4389 to the LBRAC records.
4390 (define_symbol): Handle "catch" records.
4392 * symtab.c (check_stub_type): Added new complain
4393 `stub_noname_complain' and added a consistency check to
4394 keep the debugger from crashing when finishing from an
4395 exception frame. A real fix will be needed later.
4397 Sat Feb 2 10:43:05 1991 John Gilmore (gnu at cygint.cygnus.com)
4399 * infcmd.c (attach_command): Make global.
4401 * Makefile.dist (REMOTE_OBS): Make these compile by default,
4402 but make them easy to comment out. Perhaps later they should
4403 be enabled by what CPU you configure for? FIXME.
4404 (VERSION): Roll to 3.93.
4405 (pinsn.o): Remove rule for obsolete file.
4406 (dbxread.o,coffread.o,mipsread.o): Use ${srcdir} explicitly.
4408 Run down a problem that manifested by printing the wrong function
4409 name in stack traces of read_ofile_symtab. Turned out that the
4410 problem was the SunOS 4.1.1 (and previous) C compiler outputs
4411 the LBRAC symbol with an address in the *data* segment, which
4412 blew our binary search through the blocks.
4414 * dbxread.c: Use the complain() facility consistently to bitch
4415 about problems in the symbol file we are reading.
4416 (finish_block): Add code to check the nesting of the blocks;
4417 complain and Procrust them to fit if wrong.
4418 (make_blockvector): Check the order of the blocks, complain
4419 [but don't cope] if wrong.
4420 (process_one_symbol): ifndef SUN_FIXED_LBRAC_BUG, check LBRAC
4421 symbols to be sure their PC value is greater than the last SLINE
4422 (line number) symbol we've seen, complaining and adopting the
4423 SLINE PC value if wrong.
4425 * symfile.h (struct complaint, complaint_root, complain,
4426 clear_complaints): Add.
4427 * symfile.c (complain, complaint_root, clear_complaints): Add
4428 facility to deal with non-fatal complaints and to regularize their
4430 (symbol_file_add): Clear complaint counters to allow new complaints.
4431 (initialize_symfile): Add 'set complaints' and 'show complaints'.
4433 * dbxread.c (dbx_symfile_read): Remember the address and size
4434 of the string table for the main symbol file, so we won't read it
4436 (dbx_psymtab_to_symtab): Fix the check for main symbol file,
4437 to avoid reading the string table yet again. Lint.
4438 (throughout): Improve filtered output, including word wrap.
4439 (read_range_type): Improve Bothner's fix to handle other types too.
4441 * utils.c: Improve line wrap implementation. Handle unlimited
4442 width by making chars_per_line unsigned.
4443 (puts_filtered): New, easy, function.
4445 * defs.h (puts_filtered): add.
4447 * mipsread.c (compare_symbols, sort_symtab): Remove these fns,
4448 call the identical sort_symtab_syms() in symfile.c instead.
4450 * expread.y: Suggest the `file' command rather than `symbol-file'.
4452 * command.h (enum var_types): Add zinteger for seroable
4454 * command.c (do_setshow_command): Handle var_zinteger. Restructure
4455 nested if's into a switch.
4457 * breakpoint.c (bpstat_print): If bpstat "print" flag is not set,
4458 we did not stop because of a breakpoint (it must have been for
4459 some other reason, like a "stepi"), so don't print anything.
4461 * symtab.c: Include <sys/types.h> all the time. Now that BFD
4462 doesn't include <sys/types.h>, old SunOS's require it for
4465 Sat Feb 2 10:39:15 1991 Per Bothner (bothner@cs.wisc.edu)
4467 A test port of gdb-3.92.6 to the Sony NEWS.
4470 Don't normally link in remote- or vx stuff.
4471 Some of it doesn't compile, and it wastes space for 99% of the users.
4472 Remove reference to no-longer-used HAVE_VPRINTF.
4473 Fixed BFD_DEP typo to BFD_DIR.
4475 Fix cast in arg to bfd_h_getlong.
4476 Make char *prefix be const.
4477 Fix how certain range types are mapped into builtin unsigned int types.
4479 Remove 2 #includes. They cause errors (on Sony, at least),
4480 and aren't needed (they wern't in earlier versions).
4482 print_address_symbolic should never demangle labels
4483 (since it prints *assembler-level* labels).
4485 [This was superseded by the change to printcmd below.]
4488 Add some "volatile" return types to avoid warnings.
4489 If MISSING_VPRINTF add vprintf function and not just macro
4490 (since vprintf is used in printcmd.c).
4492 Unless __GNUC__, use obstack_grow instead of obstack_ptr_grow.
4493 (The latter isn't grokked by some PCC-based compilers.)
4495 [This change is in abeyance, we prefer to fix obstack_ptr_grow.]
4497 Make chunk size of dont_print_obstack 32*4 instead of default 4096.
4498 * nindy-share/coffstrip.c
4499 Added some forward declarations (otherwise, gcc complains
4500 about implicit extern redefined as static).
4502 Sun Jan 20 02:38:19 1991 John Gilmore (gnu at cygint.cygnus.com)
4504 Changes inspired by Per Bothner:
4505 * printcmd.c (print_address_symbolic): Take additional parameter
4506 specifying whether to demangle.
4507 (print_address): Pass in asm_demangle to control demangling.
4508 (print_address_demangle): New fn, takes explicit arg to control
4510 * utils.c: Add new vars demangle and asm_demangle, and let them
4512 (fputs_demangled): If !demangle, just print the argument.
4513 (fprint_symbol): If !demangle, just print raw symbol.
4514 * valprint.c (val_print): Call print_address_demangle rather than
4515 print_address, to cause demangling to depend on the global
4516 rather than assembler-level demangling setting.
4517 * WHATS.NEW, gdb.texinfo: Document.
4519 * main.c (show_command): Show all settings if no arg.
4520 (initialize_main): Make "info set" the same as naked "show".
4521 * command.c (cmd_show_list): Handle prefix commands in the
4522 list, and print the name of the setting as well as its English
4523 description and value.
4525 Allow gdb functions to specify where a line should wrap if it
4526 exceeds the size of a terminal line. Use it to make the output
4528 * utils.c (set_screen_width_command): New fn, mallocs a buffer
4529 of the right size when screen width changes.
4530 (set_screensize_command, screensize_info): Remove #if 0'd fns.
4531 (wrap_here): New fn, indicates a point in the output where we
4532 should wrap the line rather than just letting it overflow at a
4534 (fputs_filtered): Implement wrapping.
4535 (n_spaces): New fn, returns a pointer to N spaces.
4536 (print_spaces_filtered): Use n_spaces.
4537 * defs.h (n_spaces): Declare.
4538 * stack.c (print_frame_info): Wrap with 4-space indent after
4539 fn name and before filename and line number.
4540 * printcmd.c (print_frame_args): Wrap with 4-space indent
4541 before each argument name is printed.
4542 * valprint.c (value_print): Wrap with no indentation before
4544 (val_print_fields): Wrap with indentation relative to nesting
4545 level before each field name.
4546 (val_print): Wrap with nesting indentation before array elements.
4547 * command.c (do_setshow_command): Avoid extra newlines,
4548 wrap with 4-space indent around values printed, end with period.
4549 * WHATS.NEW, gdb.texinfo, gdb-int.texinfo: Document.
4551 * breakpoint.c (breakpoint_1): Implement addressprint for
4552 "info breakpoints" display. Change file name and line number
4553 format to " at file:nnn" rather than " (file line nnn)".
4554 * gdb.texinfo: Document.
4557 Fri Jan 18 07:21:25 1991 John Gilmore (gnu at cygint.cygnus.com)
4559 Frozen for gdb-3.92.6 release.
4561 README, WHATS.NEW: Update for 3.92.6 release.
4563 tconfig/{altos, i386v, i386v32, m88k, umax}: Eliminate
4564 coffread.o from configs since it is now built by default.
4565 tconfig/{3b1, altosgas, arm, convex, hp300bsd, hp300hpux,
4566 i386v-g, i386v32-g, isi, merlin, news, news1000, np1, pn,
4567 pyramid, symmetry, vax, vxworks68}: Eliminate dbxread.o
4568 from configs since it is now built by default.
4570 Makefile.dist: Update for release 3.92.6. Handle files that
4571 have been moved to ../include, ../getopt, or ../bfd. Add
4572 saber.suppress and tests directory. Add config.status to
4573 the release (it will say "none").
4575 coredep.c: Minor formatting fixes.
4577 These changes were made in early December but only checked in now:
4578 * nindy-share/Onindy.c, nindy-share/coffstrip.c,
4579 nindy-share/nindy.c: lint
4580 * nindy-share/nindy.c (ninStopWhy): Don't byteswap the
4581 register values coming back from the target; we store values
4582 in target byte order everywhere.
4584 Wed Jan 16 19:01:37 1991 John Gilmore (gnu at cygint.cygnus.com)
4586 * am29k-opcode.h, am29k-pinsn.c: Add 29050 opcodes.
4588 * valprint.c (cplus_val_print, val_print_fields): New functions,
4589 which print C++ objects. They conspire to avoid printing a
4590 virtual base class more than once, following all the twists and
4591 turns of C++ virtual base rules.
4592 (val_print): Call the above rather than do it by hand.
4594 * symfile.c (symbol_file_add): Only reset symfile_mtime for main
4595 symbol file, not for added files like shared libs. This really
4596 needs to be generalized to a timestamp per file.
4598 * core.c (cleanup_core): Avoid coredump if no core file.
4600 * config.gdb: Accept -host or -target in place of +host or
4603 * coffread.c (find_linenos): Avoid desupported BFD interface
4604 to line numbers. We still read them manually rather than using
4605 BFD's "generic" features.
4607 * gdbrc.tex, threecol.tex: Add GDB reference card and its
4609 Makefile.dist: Add refcard to OTHERS list for creating tar files.
4611 * Makefile.dist: Eliminate use of $< in explicit targets.
4613 * readline/Makefile: Use $< rather than $*.c, which does not
4614 include the VPATH in GNU Make.
4616 * tconfig/i960-bout, tconfig/i960-coff: These are identical
4617 copies of tconfig/i960, added for global configuration
4618 compatability. All i960 versions can read both coff and b.out.
4620 * tm-88k.h: Fix multiline macro that lacked \'s. Remove
4621 COFF_FORMAT and COFF_CHECK_X_ZEROES since these are now handled
4624 * TODO: Think of more things to do.
4626 Wed Jan 2 19:09:29 1991 John Gilmore (gnu at spiff.cygnus.com)
4628 tconfig/{am29k,i960,sun2*,sun3*,sun4*}: Eliminate config
4629 of sdb versus dbx debug symbols. Add kludge for 68881 80-bit to
4630 64-bit float conversion.
4632 tconfig/sun4, tconfig/sun3, xconfig/sun4, xconfig/sun3: Make
4633 equivalent to sun?os4 so global config works.
4635 Wed Jan 2 18:20:51 1991 John Gilmore (gnu at spiff.cygnus.com)
4637 Fix from Eberhard Mattes <mattes@azu.informatik.uni-stuttgart.de>
4639 * main.c: Only declare linesize once; declare pagesize not at
4640 all, since it is never used.
4641 (main): Clear newly allocated line before it is used.
4643 Fri Dec 28 00:13:42 1990 John Gilmore (gnu at cygint)
4645 Further stabilization for the Intel 960.
4647 * Makefile.dist: Parameterize the location of the "include"
4648 and "bfd" directories, as well as "getopt". Add symfile.c.
4649 Link in both dbxread and coffread. Fix up "make depend" to
4650 rewack the locations of include, bfd, and getopt in its output.
4652 * README: Document moving include files, improve some of
4655 * coffread.c: Move common code out to symfile.c. Change
4656 symbol_file_command style interface to use new *_symfile_init
4657 and *_symfile_read interface under BFD. Use BFD internal
4658 info to locate line table, symbols, etc.
4660 * core.c (core_fetch_registers): Rename to get_core_registers
4661 to avoid confusion with fetch_core_registers.
4662 (register_addr): Move to coredep.c, which is already machine
4663 dependent. This leaves core.c pretty clean of dependencies.
4665 * coredep.c (register_addr): Accept this routine from core.c.
4667 * dbxread.c: Move common code (with coffread.c, etc) into new
4668 symfile.c. Each psymtab now contains a pointer to the
4669 format-dependent function that knows how to read it in. Make
4671 (dbx_psymtab_to_symtab): Renamed from psymtab_to_symtab_2.
4672 (process_one_symbol): Add code to complain about a "compiler bug
4673 we muzzle here", if we actually see it.
4675 * eval.c (evaluate_subexp): Insert missing "break" statements
4676 in code that determines whether a variable is an lvalue in
4677 memory, register, or whatever. I detected this via a compiler
4678 bug in which it *almost* mashed out the whole switch statement.
4680 * gdb-int.texinfo: Add minor sections on configuring gdb for
4681 release, and about the README file.
4683 * infcmd.c (registers_info): Fix formatting somewhat. Still
4684 not as pretty as before, but it handles byte swapping.
4686 * remote-nindy.c: If data cache routines are interrupted while
4687 waiting for the remote end, be sure that any uninitialized cache
4688 blocks are on the free list, not on the valid list!
4690 * symfile.h: Flesh out this header file with all the various
4691 routines and variables that have been merged in from dbxread.c
4692 coffread.c, and symtab.c to symfile.c.
4694 * symfile.c: New file, containing code common to dbxread.c,
4695 coffread.c, and some code from symtab.c. All generic code for
4696 reading symbol files should be in here now.
4697 (unrecord_misc_function): Remove unused function.
4699 * symtab.h: Remove file-reading things to symfile.h.
4701 * symtab.c: Remove file-reading things to symfile.c.
4703 * tm-i960.h: Fix FRAME_CHAIN types; define PRINT_RANDOM_SIGNAL
4704 to decode i960 fault types.
4706 * target.h, remote.c, remote-eb.c, remote-vx.c, remote-nindy.c,
4707 target.c: Change type of the "resume" function from int to void,
4708 since its result was never used.
4710 Sat Dec 22 02:51:40 1990 John Gilmore (gnu at cygint)
4712 * main.c: Replace "stupid" with "caution"; you now "set caution
4715 * printcmd.c (print_scalar_formatted): Fix typo in 'g' format
4717 * infcmd.c (do_registers_info): Call val_print to deal with the
4718 byte order of the registers being printed. FIXME, this makes
4719 the formatting of the output uglier.
4721 * infcmd.c (wait_for_inferior): If PRINT_RANDOM_SIGNAL is
4722 defined, call it for signals the debugger doesn't itself use.
4723 The i960 uses this for more detailed fault information.
4725 * remote.c (remote_open): If arg is null, print help rather than
4728 * sparc-xdep.c (register_valid): Avoid declaring size, since
4729 various modules will think of various sizes depending on the
4730 architecture of their tm-file. FIXME, we need protection against
4731 actually entering one of those modules, which would clobber
4732 storage if not for the target architecture compiled into gdb.
4734 * stack.c (up_command, down_command): Always print the frame
4736 (up_silently_command, down_silently_command): New commands
4739 * i960-pinsn.c (reg), i960-tdep.c: Lint.
4741 * i960-tdep.c (i960_frame_chain_valid): Lookup_symbol now takes
4742 more parameters than it used to.
4744 * findvar.c (registers): Increase slop to 256 bytes, which should
4745 protect us against even most RISC machines with large register
4747 (locate_var_value): Move declaration inside related ifdef.
4749 * remote-nindy.c (): Use TIOCSETN rather than TIOCSETP
4750 throughout, to avoid throwing away buffered input from the board.
4751 (nindy_wait): Supply_register takes addr_of_value, not value.
4752 (i960_print_fault): Renamed from i80960_fault.
4753 (nindy_fetch_registers): Avoid have_regs stuff, just get them.
4754 (nindy_store_registers): Avoid regs_changed stuff, just stuff
4756 (nindy_create_inferior): Don't bother to write PC_REGNUM since
4757 we can set the PC in the call to proceed(). Unpush nindy_ops
4758 before pushing it on top, to avoid message to user. Eliminate
4759 commentary from Unix machines that just misleads here.
4760 (reset_command): Fix error message to suggest target command.
4762 Wed Dec 19 11:03:56 1990 John Gilmore (gnu at cygint)
4764 Release 3.92.5 as frozen.
4766 Stabilize the merged release...with help from lint, Saber C,
4769 Everywhere: Add include files needed to declare return types
4770 of functions called.
4772 * gdb.texinfo: Roland Pesch is documenting gdb, glory be!
4774 * breakpoint.h: Add undeclared breakpoint functions, and some
4775 functions for display handling since I couldn't think of a better
4778 * breakpoint.c (insert_breakpoints): Make code for disabling
4779 shared library bkpts more likely to work. It's used when we
4780 rerun a program and stop before the shared library has been
4782 (breakpoint_cond_eval, bpstat_stop_status): Pass arg as int,
4783 cast from pointer, so it squeezes through catch_errors.
4784 (bpstat_stop_status): Fix logic broken some time ago. We now
4785 always create a bpstat if the stop address matches a breakpoint,
4786 even if we don't stop there -- just like the old code used to do
4787 before I got my fingers into it (sigh).
4788 (breakpoint_1): Print "ignore count" after "stop only if"
4789 condition, since that's how it actually works.
4790 (mention): Handle watchpoints as well as breakpoints.
4791 (watch_command): use set_raw_breakpoint and mention to do most
4792 of the work (and initialize all the fields!). Only pass one
4793 arg to parse_c_expression, since that's all it takes.
4795 * command.c (not_just_help_class_command): Rename arg to args
4796 since we ignore "unused argument" warnings on vars named "args".
4797 inflow.c (child_terminal_info): ditto.
4798 infptrace.c (kill_inferior): ditto
4799 main.c (catch_errors, version_info, quit_command, pwd_command,
4800 source_command, dump_me_command, editing_info,
4801 set_history_size_command, set_history, show_history,
4803 stack.c (locals_info): ditto
4804 target.c (target_files_info): ditto
4805 valprint.c (set_input_radix, set_output_radix): ditto
4807 * core.c: Remove old variables for handling core and exec file
4808 sections (data_start, data_end, stack_start, stack_end,
4809 reg_stack_start, reg_stack_end, reg_stack_offset, text_start,
4810 text_end, exec_data_start, exec_data_end, text_offset,
4811 exec_data_offset, data_offset, stack_offset). They're
4812 superseded the more general build_section_table and
4814 (get_exec_file): Mention the `file' command.
4815 (read_memory_check): Rename to memory_error, and only call it
4816 in the case of an actual error.
4817 (read_memory, write_memory): call memory_error.
4818 (core_fetch_registers): Register section name is ".reg".
4820 coredep.c: Remove a bunch of crud now that all this file does
4821 is pull the registers out of a core file.
4822 (fetch_core_registers): Rewrite to actually work, I hope.
4824 dbxread.c: Use a.out.gnu.h, not system a.out, now.
4825 Replace index() with strchr(). Remove all the pre-BFD macro
4826 definitions for accessing the symbol file.
4827 (struct dbx_symfile_info): Encapsulate the information that
4828 dbx_symfile_init needs to pass to dbx_symfile_read in this
4831 (dbx_new_init, dbx_symfile_init, dbx_symfile_read,
4832 dbx_symfile_discard): Rearrange symbol file reading to divide
4833 the format-specific part from the format-independent part,
4834 leaving the format-independent part such as file name expansion
4835 and opening in symtab.c. This replaces
4836 partial_symbol_file_open and partial_symbol_file_read.
4837 Symbol_file_read, add_file, add_file_target_command,
4838 add_file_addr_command move to symtab.c. Pass an explicit
4839 "mainline" flag for when reading the main symbol table, rather
4840 than relying on the offset address to be zero or nonzero.
4842 (dbx_symfile_read): Don't allow void *'s to be printed as
4844 (SWAP_SYMBOL): Use bfd routines to byte-swap the symbols.
4845 (ADD_PSYMBOL_TO_LIST): Make the "function call rather than
4846 macro" debug version really work.
4847 (read_dbx_symtab): Remove unref'd parameter inclink.
4848 Avoid swapping N_SLINE symbols, for speed.
4849 Merge N_TEXT!N_EXT case with the other external symbol
4850 definitions' case. Add comments.
4851 (start_psymtab): Allocate the symfile name in the psymtab on
4852 the psymbol_obstack, rather than using the caller's storage.
4853 (end_psymtab): Only allocate a dependencies list if there are
4855 (psymtab_to_symtab_2): Use BFD when reopening file to read
4856 its symbols for real.
4857 (read_struct_type): Add FIXME comments where it needs work
4859 (read_huge_number): Add FIXME about overflows.
4860 (read_range_type): Add FIXME about comparing a long to 1<<32.
4862 * coffread.c: Minor changes to move things closer to the new
4863 regime with symtab.c and dbxread.c Major work is still needed
4866 * exec.c (exec_file_command): Remove old variables (see core.c
4868 (xfer_memory): If memory transfer is right at the end of a
4869 section, don't lose.
4871 * findvar.c (get_saved_register): If value is in a real
4872 register, LVAL is lval_register, not lval_memory.
4874 frame.h: Declare print_sel_frame and record_selected_frame.
4876 gdb-int.texinfo: New file, for GDB internals documentation.
4877 Very simple, unformatted doc of cleanups is there for now.
4879 gdbcore.h: Remove obsolete variables that described a.out
4880 section addresses and offsets. (See core.c above.)
4881 Declare fetch_core_registers and registers_fetched.
4883 getopt.c: Declare char *alloca(); even on SPARC.
4885 infcmd.c (run_command): Call target_kill rather than
4887 (step_command, next_command, stepi_command, nexti_command):
4888 Declare from_tty parameter even though we don't use it.
4889 (run_stack_dummy): argument BUFFER is a char array, not
4890 a pointer to REGISTER_TYPE.
4891 (finish_command): using_struct_return needed a value *,
4892 not a struct symbol *.
4894 * infptrace.c (child_xfer_memory): To avoid dependency on
4895 where sections are in memory, try PT_WRITE_D and if that fails,
4896 try PT_WRITE_I. Most Unixes don't care which you use.
4898 * infrun.c (step_resume_break_shadow): Change to array to
4899 match other breakpoint shadow storage.
4900 (clear_proceed_status): Pass address of bpstat to
4901 bpstat_clear, not the bpstat itself.
4902 (child_create_inferior): FIXME comment about if the child
4904 (start_inferior): Remove old function.
4905 (child_open): Use target_kill rather than kill_inferior.
4906 (wait_for_inferior): Ditto.
4907 (insert_step_breakpoint, remote_step_breakpoint): Use
4908 new step_resume_break_shadow.
4910 * inftarg.c (child_wait): If all child processes die,
4911 pretend that the one being waited for exited with signal 42.
4913 * main.c (command_line_input): When scanning for comments,
4914 don't coredump on unclosed quotes.
4915 (quit_command): Use target_kill rther than kill_inferior.
4916 (_initialize_main): Rename class_user from "user" to
4919 * printcmd.c (print_command_1): Initialize "fmt" if no format
4920 is specified by the user.
4921 (print_frame_args): Only add to args_printed if we are
4922 actually fetching args from the stack (avoiding undefined
4924 (_initialize_printcmd): Remove bogus \{ from string.
4926 * remote-eb.c (eb_open): Avoid coredump on no argument.
4928 * remote-nindy.c: Bring out of Intel environment into new
4929 target environment. Remove all conditional compilation on
4930 I80960. Massive hacking throughout.
4931 (nindy_xfer_inferior_memory): New routine stolen from
4933 (nindy_create_inferior): New routine pieced together, probably
4934 not quite working yet.
4935 (nindy_ops): New target_ops struct for nindy.
4937 * remote-vx.c: Use write_memory rather than target_write_memory
4938 to get error checking.
4939 (vx_add_file_command, vx_open): Use symbol_file_add rather than
4941 (vx_create_inferior): Use target_terminal_ours...
4943 * signame.c (_initialize_signame): Always initialize, since
4944 we need the table for things other than psignal.
4946 * solib.c (solib_add): Use symbol_file_add, not add_file.
4947 (solib_address): Return boolean result rather than struct
4948 pointer which nobody else knows the type of.
4950 * sparc-tdep.c, valops.c: Use write_memory rather than
4951 target_write_memory, to get error checking.
4953 * stack.c (locals_info, catch_info, args_info,
4954 get_selected_block, frame_command, up_command): Use
4955 target_has_stack, rather than have_inferior_p or
4958 * sun3-xdep.c (fetch_core_registers): Rewrite for new BFD regime.
4960 * symfile.h: New file, defining the interface between the
4961 generic and object-file-specific symbol reading code.
4963 * symtab.c: Move generic symbol-reading interface to symtab.c,
4964 from dbxread.c, coffread.c, mipsread.c, etc. Add symtab_fns
4965 table to map BFD targets to symbol-reading modules in GDB.
4966 Change index to strchr.
4967 (lookup_struct_elt_type): Use error() rather than hand-made
4968 simulations thereof.
4969 (lookup_partial_symbol): Speedup slightly when length == 0.
4970 (symbol_file_add): New function.
4971 (symbol_file_command): Call it.
4972 (symfile_open, symfile_init): New function.
4973 (add_file_target_command, add_file_addr_command): moved from
4976 * target.c (target_command): use target_kill.
4978 * target.h (target_files_info): Don't declare, never called
4981 * tm-sun2.h, tm-sun3.h (STACK_END_ADDR): Use system include
4982 files to determine stack end address.
4984 * valarith.c (value_x_binop, value_x_unop): Change error message
4985 to be more useful. Pass proper argument to value_struct_elt.
4987 * valops.c (value_assign): FIXME comment that long long
4988 bitfields will break here.
4990 * Makefile.dist: Add symfile.h, remote-nindy.c, remote-eb.c.
4991 Update `make saber_gdb' to work better.
4993 * TODO: A woman's work is never done.
4995 * cplus-dem.c, environ.c, inferior.h, infrun.c, inftarg.c,
4996 main.c, obstack.c, printcmd.c, remote-eb.c, remote-nindy.c,
4997 remote-vx.c, remote.c, solib.c, source.c, sparc-pinsn.c,
4998 sparc-tdep.c, sparc-xdep.c, symmisc.c, symtab.c, symtab.h
4999 target.c, terminal.h, tm-sparc.h, tm-sunos.h, utils.c,
5000 valops.c, valprint.c, exec.c: Lint.
5003 Wed Dec 12 23:44:15 1990 John Gilmore (gnu at cygnus.com)
5005 Continuing Intel 960 port merge of GDB.
5007 * Makefile.dist: Merge i960 "nindy-share" files. Rename
5008 malloc.h to gmalloc.h to avoid name conflicts in /usr/include.
5009 Don't ship gdb.dvi in tar file. Link gdb with init.o, not init.c.
5010 Wack over "make depend" so it handles files in subdirectories
5011 vx-share, nindy-share, bfd, and in the current directory.
5013 * blockframe.c (get_prev_frame_info): Remove fatal error
5014 if stack not defined.
5016 * core.c (core_open, core_detach): New functions that handle
5017 the old "core-file" command as "target core" and "detach" instead.
5018 (core_file_command): Call them.
5019 (core_xfer_memory): Use common routine xfer_memory.
5021 * dbxread.c: Include a.out.gnu.h, not system a.out.h.
5022 dbxread now uses bfd for everything but symbol reading itself.
5023 BFD internals are used to drag out the relevant file offsets.
5024 (partial_symbol_file_open): Change args all around for BFD.
5026 * symtab.c: Rename "value" to "val" everywhere, so we can
5028 (symbol_file_command): New command, moved from dbxread.c
5029 and coffread.c. It uses BFD to read the file, then vectors
5030 based on its type, to dbx or coff symbol readers.
5031 * symtab.h: Extern a few vars for symbol_file_command.
5033 * target.h: Breakpoint takes a char * save area, not a char **.
5035 * valprint.c (val_print): When unpacking bitfields, offset
5036 the address in gdb of the value, if it is declared with a shorter
5037 type. Remove the last "runtime kludge test" of host byte order.
5039 * utils.c: Remove old my_bfd_read routine.
5041 * stack.c (frame_info): Use target_has_stack. Print program counter
5042 register's actual name rather than "pc", since it's called the
5043 "ip" (instruction pointer) on the i960 (sigh).
5045 * target.c (target_command): Add command for selecting a target
5046 type and calling its open routine. This is used for initiating
5047 communication with a particular target, in a generic way.
5049 * tm-i960.h: Update for modern gdb. Remove semicolons from
5050 various macros. Handle reading struct return convention, and
5051 error-out attempts to return structs with the "return" command.
5052 Be sure gdb doesn't think we know how to call functions in the
5055 * i960-tdep.c: Rename FRAME_CHAIN_VALID and FRAME_FIND_SAVED_REGS
5056 to i960_xxx in lower case.
5057 (arg_address): Circumvent errors due to LOC_ARG_BLOCK
5058 not being defined yet.
5060 * remote.c (remote_open): Call start_remote to initialize
5061 wait_for_inferior during open.
5062 (remote_xfer_inferior_memory): Return length written rather
5065 * remote-vx.c (target_command -> vx_open): Use new generic
5067 * remote-eb.c, inftarg.c, exec.c: ditto.
5069 * infrun.c: Fix comments.
5070 (attach_program -> child_open): Use new generic target command.
5071 (wait_for_inferior): Clear saved register values before target_wait,
5072 so target_wait can set some of them if convenient.
5074 * infptrace.c (fetch_inferior_registers, store_inferior_registers):
5075 Return success indicator, not void.
5076 (child_xfer_memory): Avoid fetching initial word if we'll
5077 overwrite it anyway.
5079 * infcmd.c (attach_command): Use new generic target open routine.
5080 (_initialize_infcmd): Update doc on attach and detach commands.
5081 (do_registers_info): Merge in a byte-order problem as a FIXME
5084 * findvar.c (find_saved_register): Avoid problem in current frame.
5085 (read_relative_register): Ditto.
5086 (write_register): Convert byte order on the way out.
5088 * exec.c (file_command): Add.
5089 (add_to_section_table, exec_command): Use new bfd_map_over_sections.
5090 (xfer_memory): Common function between core_xfer_memory and
5092 (exec_xfer_memory): Use it.
5094 * pn-opcode.h: Document that a "PN" is a Gould PowerNode.
5096 * breakpoint.c, breakpoint.h, symtab.h, value.h, frame.h, utils.c,
5097 valops.c, stack.c, target.c, sparc-xdep.c, source.c, printcmd.c,
5098 infcmd.c, i960-pinsn.c, eval.c, defs.h: lint and gcc -Wall.
5100 Sun Dec 2 16:45:06 1990 John Gilmore (gnu at cygnus.com)
5102 Merge Intel 960 port of gdb, continuing...
5104 * dbxread.c (partial_symbol_file_open, partial_symbol_file_read,
5105 symbol_file_command): Pass from_tty arg to hush 'em up.
5107 * coffread.c (symbol_file_command): Avoid output if from_tty != 1.
5108 Add magic numbers for 960 COFF format.
5110 Fri Nov 30 09:18:20 1990 John Gilmore (gnu at cygnus.com)
5112 Merge Intel 960 port of gdb, from Intel "1.2" release.
5114 CHANGE_LOG entries from their port, which was based on
5117 Thu Sep 6 11:02:22 PDT 1990
5118 Remove temp file if download is interrupted.
5120 Wed Aug 1 09:08:33 PDT 1990
5121 Now uses binary protocol to talk to NINDY.
5122 Old hex protocol (NINDY 2.13 and older) supported with -O switch.
5123 Times out after 5 seconds when trying to talk to NINDY.
5125 Tue May 29 12:54:49 PDT 1990
5126 Added variable baud rate (-b switch).
5127 Source code reorganization.
5129 Thu Apr 26 11:09:55 PDT 1990
5130 More cleanup of batch mode; specifically, execute "-s", "-e", and
5131 "-se" switches as soon as they are encountered on the invocation line.
5133 Fri Apr 20 13:47:15 PDT 1990
5136 Thu Apr 19 09:54:28 PDT 1990
5137 Add 'reset' command.
5139 Wed Apr 18 09:48:07 PDT 1990
5140 After opening remote tty, wait for 1 second to go by without input
5141 from it before trying to talk to NINDY (fixes problems with the
5142 Heurikon HK80/V960E).
5144 Mon Apr 4 16:33:05 PDT 1990
5145 Some output was not being suppressed in 'batch' mode.
5147 Thu Mar 22 15:31:11 PST 1990
5148 Ask user if old symbol table should be deleted when new file is
5151 Allow user to run a program downloaded before gdb960 was brought up.
5153 Correct "exec-file" help message for i80960 context.
5155 Correct bug in calculating user space address: could occasionally
5156 corrupt user program.
5158 Make sure to zero low-order bits in rip's because of bug in 960CA
5159 A-step part: could cause operation faults when "next"ing across
5162 Correct bug that made it impossible to get source line numbers for
5163 code loaded at addresses higher than 0x7fffffff.
5165 Wed Jan 10 12:43:22 PST 1990
5166 Open remote tty for exclusive use.
5168 Fri Jan 5 12:14:42 PST 1990
5169 Correct disassembly (CA manual was right after all):
5170 opcode for sysctl is 0x659
5172 Mon Oct 23 12:03:04 PDT 1989
5173 Use G960BASE and G960BIN environment variables to find 'sx' utility.
5175 Mon Oct 16 14:15:09 PDT 1989
5176 "sfr0"-"sfr31" should have been named "sf0"-"sf31"
5178 Mon Oct 2 15:56:31 PDT 1989
5180 Added 960CA disassembly support.
5182 To simplify maintenance:
5183 - eliminated use of symblic links on pinsn.c: use i960-pinsn.c
5185 - eliminated opcode.h: incorporates tables into i960-pinsn.c
5186 - moved 960-specific routines from i960-pinsn.c to i960-md.c
5187 - made disassembly interface identical to that in gdmp960.
5191 Wed Nov 28 21:32:48 1990 John Gilmore (gnu at cygint)
5193 * target.h: Allow targets to stack. Add target_has_memory,
5194 _registers, etc. Restructure memory access and "info files"
5195 to walk the target stack.
5196 * exec.c, core.c, inftarg.c, remote.c, remote-vx.c, remote-eb.c,
5197 target.c: Change tables to match target.h.
5198 * inflow.c (child_mourn_inferior): pop child_ops.
5199 (generic_mourn_inferior): Use new has_stack flag.

5202 * remote-eb.c: New memory regime, new info files.
5203 * remote-vx.c: New memory regime, new info files. Now use
5204 separate targets for VxWorks attachment to machine, and
5205 actually running a process under VxWorks, since one has
5206 stack & execution & regs and the other doesn't.
5207 * remote.c: New memory regime, new info files.
5208 * sparc-xdep.c (fetch_core-registers): New memory regime.
5209 * target.c: New routines and support for stacked targets,
5210 new memory regime, new info files regime.
5213 Generalize section handling for an arbitrary number of sections,
5214 including use of the new BFD (binary file) library.
5215 * gdbcore.h: Add struct section_table.
5216 * exec.c (build_section_table): Iterate all sections and
5217 record what gdb needs to know about them.
5218 (exec_command): Use it.

5224 * dbxread.c: Quick changes to make it compile with new BFD.
5225 * utils.c (error): Avoid using bfd_error in generic routines.
5227 * core.c (core_fetch_registers): Get from the ".regs" section of
5229 * sparc-xdep.c (fetch_core_registers): Use the .regs info.
5231 * inferior.h (attach_flag): Export.
5232 * infcmd.c (run_command): use new target_create_inferior.
5233 * infrun.c (child_create_inferior): Don't return result.
5234 * Makefile.dist (VERSION): 3.91.4.
5236 Fri Nov 23 28:15:38 1990 John Gilmore (gnu at cygint)
5238 * breakpoint.c (bpstat_num): Handle breakpoints which have
5239 since been deleted, such as temporary breakpoints.
5240 infcmd.c (program_info): ditto.
5242 * core.c (core_file_command): Display the frame where the core
5247 * remote-vx.c (target_command): Merge in target command from
5248 targ-vx.c. A few other cleanups.
5250 * TODO, Projects: Lots more stuff to do...
5252 Fri Nov 23 18:15:38 1990 John Gilmore (gnu at cygint)
5254 Massive changes to wall off the remote-debugging interface
5255 behind a function vector. The port to handle VxWorks targets
5256 is also part of this.
5258 All files: Replace references to renamed functions,
5259 remove references to remote_debugging, remove references to
5260 have_include_file, have_core_file in favor of target_has_stack,
5261 target_has_memory, etc.
5263 * Modularize the breakpoint interface.
5264 breakpoint.h (BREAKPOINT_MAX): New define sets max length of
5265 a breakpoint instruction.
5266 breakpoint.c: struct breakpoint's shadow_contents now sized as
5268 (insert_breakpoints): Vector to target to install breakpoints.
5269 (remove_breakpoints): Vector to target here too.
5270 Remove REMOTE_SA_SPARC kludges and other remote_debugging.
5271 sparc-tdep.c (single_step): Use new breakpoint interface for
5272 the single-step breakpoints.
5273 mem-break.c (memory_insert_breakpoint, memory_remove_breakpoint):
5274 New file, contains routines to insert and remove breakpoints by
5275 reading out the old contents and later replacing them. This is
5276 how ptrace breakpoints work, and many remote systems as well.
5278 * tm-vxworks68.h: New config file, overrides a few things for
5279 Wind River's preferences.
5281 * target.h: New file, for transfer vector used to talk to the
5282 inferior (child, attached, core, exec, remote, etc). All accesses
5283 to the thing being debugged should come through these vectors.
5284 target.c: New file, routines to handle transfer vector.
5285 (various files): Add transfer vectors XXX_ops for the various
5286 targets and pseudo-targets (core files, etc) we support.
5288 * breakpoint.c (bpstat_stop_status): Further explorations of
5289 watchpoints and why things don't work all the time.
5290 (bpstat_alloc): New fn to allocate a bpstat and chain it.
5292 * config.gdb: Only add "source ${srcdir}/.gdbinit" to
5293 the local gdbinit if it doesn't already have it.
5295 * core.c (core_ops): add and install.
5296 Allow core debugging without exec file.
5298 * dbxread.c (free_and_init_header_files): Merge two fns.
5299 (end_symtab): Free named symbol table when a new version comes in.
5300 (read_dbx_symtab): Relocate all kinds of symbols with base
5301 address. First step toward handling different text, data, bss
5303 (add_file_addr_command): Renamed add_file_command.
5304 (add_file_command): Vector to remote handler.
5305 Add "load" as an alias for "add-file" command.
5307 * defs.h: Allow "volatile" to be used in non-ANSI; use it for
5308 non-returning functions.
5310 * exec.c: Add exec_ops, and push it as a target when an exec
5313 * infcmd.c (run_command): Pass executable file name and arg list
5314 separately when starting an inferior. Permit "run" when no exec
5315 file is specified, for VxWorks.
5316 (detach_command): Move to child_detach in inftarg.c.
5318 * inftarg.c: New file. Unix-child-specific routines, and the
5319 child_ops structure.
5321 * inferior.h (registers): Export "registers" as the way for
5322 target dependent register handlers to find gdb's local copy of
5323 the registers. Rename "stop_after_attach" to "stop_soon_quietly"
5324 since it is now used by places that want wait_for_inferior to
5325 handle the grunge but want to see every trap from the inferior.
5327 * inflow.c (create_inferior): Pull out, and merge into infrun.c.
5328 Eliminate remote_debugging hooks in terminal handling.
5330 * infrun.c: Replace start_inferior with child_create_inferior.
5331 Move all the hair of Unix shells and ptrace idiosyncracies into
5332 child_create_inferior, so remote handlers don't have to deal.
5333 Remove running_in_shell. Rename stop_after_attach to
5334 stop_soon_quietly, and use it in a few other places where we want
5335 to just call wait_for_inferior and get control back on the first
5336 trap. trap_expected now never takes a value > 1.
5337 (init_wait_for_inferior): Initialize static vars when a new
5340 main.c (gdbinit): Add new hook for .gdbinit file name, let
5341 it be overridden by config files as GDBINIT_FILENAME.
5342 (DEFAULT_PROMPT): Add new hook for overriding (gdb) prompt.
5343 Both of these are used for VxWorks gdb.
5345 mcheck.c: rename include file "gmalloc.c" to avoid problems
5346 with system include file "malloc.c".
5348 param-no-tm.h: New include file, same as param.h but does not
5349 include the default "tm.h" file. This is used in files where
5350 the target is known, e.g. remote-eb.c or sparc-xdep.c.
5352 param.h: Now just a shell that includes tm.h and param-no-tm.h.
5354 remote-vx.c: New file, VxWorks remote debugging support. Uses
5355 RPC routines that are shared with the target system, in directory
5358 remote.c: Vectorize remote interface.
5360 source.c: Globalize source_path, and make an alias "l" for "list"
5361 since we now have the "load" command.
5363 sparc-xdep.c: Use new param-no-tm.h.
5365 symmisc.c (free_named_symtab): Add new function from Wind River.
5366 However, ifdef it out for now while we think about what it should
5369 tm-sun3.h, xm-sparc.h, xm-sun3.h, xm-symmetry.h: Move
5371 the xm- file, and change its name to CHILD_PREPARE_TO_STORE, since
5372 non-Unix-children handle this with their own code in the target
5375 Makefile.dist: Roll version to 3.92.3. Add vx-share stuff to
5376 source and target lists. Add vx-share to default list of include
5377 directories. Add new files to src and target lists: mem-break,
5378 target, inftarg, remote-eb, remote-vx, targ-vx. Be sure the
5379 ${srcdir} versions of munch and createtags are used.
5381 * valops.c (find_function_addr): Split out of call_function.
5382 (call_function_by_hand): Rename call_function; this function
5383 calls functions in the target by laboriously patching the target
5384 word-by-word with the right stack, args, regs, etc.
5387 Mon Nov 5 17:29:10 1990 John Gilmore (gnu at cygint)
5389 Handle AMD 29000 a bit better.
5391 * remote-eb.c (readchar): Mask received char log to make it readable.
5392 (remote_start): Pass arguments down to executing program.
5393 Make startaddr unsigned.
5394 infrun.c (start_inferior): Accept args, pass them to
5396 infcmd.c (run_command): Pass args down to start_inferior.
5398 * tconfig/am29k-aout, tconfig/am29k-coff: New files specifying
5399 the target object file format.
5400 tm-29k.h: Pay heed to COFF_ENCAPSULATE.
5402 * am29k-pinsn.c (print_insn): Print 0x on hex numbers in disassembly.
5403 am29k-tdep.c (examine_prologue): Better checking of function prefixes.
5405 Sun Oct 7 18:20:45 1990 John Gilmore (gnu at cygint)
5407 * Makefile.dist (VERSION): Roll version to 3.91.9 and freeze.
5408 * TODO: We did a few things, we have more to do though.

5411 * inflow.c (inferior_died): Clear deferred stores.
5413 * Debug problems with dummy frames and calls to the inferior.
5414 * tm-sparc.h (PUSH_DUMMY_FRAME, POP_FRAME): Move to sparc-tdep.c.
5415 * sparc-tdep.c (do_restore_insn): Simplify.
5416 (sparc_frame_find_saved_regs): Simplify and fix what we find.
5417 (sparc_push_dummy_frame): Simplify and fix what we push.
5418 (sparc_pop_frame): Slightly more hair here, deciding whether
5419 we are restoring a saved PC or returning to a return address in %i7.
5420 * sparc-xdep.c (read_inferior_registers): Debug if valid reg is read.
5422 * utils.c (xmalloc, xrealloc): Return type depends on __STDC__.
5423 * symtab.h (xmalloc): ditto, for obstack_chunk_alloc.
5424 * obstack.h (chunkfun): ditto.
5425 * defs.h (xmalloc, xrealloc): ditto
5427 * utils.c (quit): Grab the terminal from the child if necessary.
5429 * inflow.c (term_status_command): Rename to term_info, change
5432 * sparc-pinsn.c (print_insn): Disassembly prefers real instructions.
5433 (is_delayed_branch): Speed up.
5434 * sparc-opcode.h: Add ALIAS bit to aliases. Fix up opcode tables.
5435 Still missing some float ops, and needs testing.
5437 * Support for input and output radixes other than base 10
5438 * defs.h (input_radix, output_radix): Declare.
5439 * expread.y (yyparse, parse_number): Handle changes of input
5440 radix, and ambiguous names-or-numbers in radixes >10.
5441 * printcmd.c (print_scalar_formatted): Print formatted hex
5442 numbers in varying column widths.
5443 * valprint.c (val_print): Use output_format to print scalar ints.
5444 (set_input_radix, set_output_radix, set_radix): Create.
5445 (set_output_radix): Set output_format from output_radix.
5446 (_initialize_valprint): add `set radix' but leave the others off.
5448 * main.c (execute_command): Let stupid questions be turned off.
5449 (_initialize_main): Handle "set stupidity", etc.
5451 * main.c, inflow.c, inferior.h, frame.h, command.c, defs.h,
5452 sparc-pinsn.c, sparc-xdep.c, value.h, valops.c, values.c: Lint.
5454 Tue Oct 2 11:20:02 1990 John Gilmore (gnu at cygint)
5456 * TODO, Makefile.dist, ChangeLog: Freeze for 3.91.8 release.
5457 bfd stuff is still screwed up, but with some manual work, it
5460 * breakpoint.c (bpstat_do_actions): Start over if a command
5461 proceeds the inferior, since the inferior will have stopped and
5462 will need to have its new stop-actions taken care of.
5464 * dbxread.c (read_struct_type): Expression gives Sun3 4.0.3
5465 compiler fits, simplify it.
5467 * gdb.texinfo (directory command): Doc new dir command.
5468 source.c (directory_command): "dir" now puts things on the front
5469 of the path, moves dups up front, and handles multiple names
5470 on the command line, inserting each one in order. It also
5471 blows away cached line and full_filename info.
5473 * stack.c (backtrace_command): Skip "more stack frames follow"
5476 * Change #ifndef HAVE_VPRINTF to #define MISSING_VPRINTF in
5477 xm-convex.h, xm-hp300bsd.h, xm-isi.h, xm-merlin.h, xm-news.h,
5478 xm-np1.h, xm-pn.h, xm-pyr.h, xm-symmetry.h, xm-umax.h, xm-vax.h.
5479 The only odd one was Gould NP1, which had defined vprintf to
5482 * Merge Ted Goldstein <tedg@Eng.sun.com>'s changes for epoch.
5483 printcmd.c (print_command_1): Pass 'inspect' flag down as a global
5484 variable, inspect_it.
5485 valprint.c (print_string, val_print): Use the global inspect_it
5486 to indicate whether to print in Epoch style or normal style.
5488 Mon Oct 1 23:55:26 1990 John Gilmore (gnu at cygint)
5490 * printcmd.c (call_command): add an alias for the "print" command
5491 which runs expressions and doesn't print the result if void.
5492 (print_command_1): implement it.
5494 * command.c: Remove #if 0'd code. Initialize all the fields
5495 in add_cmd (). Rename do_nothing_command to
5496 not_just_help_class_command, and make it externally visible.
5497 command.h: add user_commands to struct.
5498 * main.c (define_command): Don't overload c->function with a char
5499 string as well as a function pointer.
5501 * eval.c (evaluate_subexp): Reinstall tiemann changes to
5502 calling convention of value_struct_elt () that got dropped in
5505 * tm-sparc.h (FRAME_FIND_SAVED_REGS): move to sparc-xdep.c.
5506 sparc-tdep.c (sparc_frame_find_saved_regs): ditto.
5508 * tm-sparc.h (POP_FRAME): replace some constants with defines.
5510 * sparc-xdep.c (store_inferior_registers): defer stores to regs
5511 until a good time (e.g. when we are about to run the child),
5512 saving ptrace calls.
5513 * infrun.c (proceed): handle DO_DEFERRED_STORES.
5514 * tm-sparc.h: define DO_DEFERRED_STORES.
5516 * sparc-xdep.c (store_inferior_registers): when storing float
5517 registers, don't store stack regs too. When storing the SP,
5518 however, DO store the stack regs too. This fixes a bug in which
5519 the dummy frame is not recognized when a call_function finishes,
5520 because its frame pointer (in the stack regs) was never
5522 (read_inferior_registers): Mark WIM and TBR and FPS and CPS valid
5523 even though we don't know how to read them from an inferior.
5524 valops.c (call_function): Comment about storing SP.
5526 * infrun.c (save_inferior_status): Save away the original bpstat
5527 chain so it can be restored later. Install the copied version for
5528 use by whoever saved the status. It will be blow away by
5529 restore_inferior_status, and the original chain restored. This is
5530 important for people who have pointers into the original.
5532 * breakpoint.c, command.h, copying.awk, dbxread.c, defs.h,
5533 findvar.c, frame.h, obstack.h, obstack.c, inflow.c, value.h,
5534 main.c, printcmd.c, sparc-tdep.c, symtab.c, valprint.c: lint
5537 Fri Sep 28 20:32:46 1990 John Gilmore (gnu at cygnus.com)
5539 * Makefile.dist: Roll version to 3.91.8. Add bfd.h and bfdconfig.h
5540 temporarily to the makefile. Add am29k-opcode.h and WHATS.NEW.
5541 Add stuff.c and kdb-start.c to the OTHERS list for tar files.
5543 Fri Sep 28 19:12:12 1990 John Gilmore (gnu at cygint)
5545 * Merge Mike Tiemann's multiple inheritance changes from Sun.
5546 Store the baseclasses in a type struct starting from array element
5547 0 rather than from the unusual array element 1.
5549 dbxread.c: the above.
5550 (virtual_context): Add
5551 Read new debug information about which virtual function table
5552 a virtual function is from, and store it in fn_field.fcontext.
5554 symtab.h: Add fcontextt. Fix baseclass indices. Typo in
5555 TYPE_FN_FIELD_STATIC_P.
5557 symtab.c: the above.
5558 valops.c: the above. Handle pointer casts of object *'s.
5559 (search_struct_method): Add.
5560 (value_struct_elt): First arg is now a pointer to a value, and is
5563 valprint.c: the above.
5564 values.c (value_virtual_fn_field): Add type arg. Handle
5565 offsetting to the proper object when calling virtual fns.
5567 (baseclass_addr): Add valuep arg.
5569 * README: Document the current state of BFD config (missing).
5570 * TODO, ChangeLog, Makefile.dist: Roll version.
5571 * WHATS.NEW: Add summary of changes since 3.5.
5573 Thu Sep 27 16:23:12 1990 John Gilmore (gnu at cygint)
5575 * dbxread.c (read_struct_type): Clear bit vectors whenever
5577 symtab.c (B_CLRALL): define.
5579 * tm-sparc.h (STORE_RETURN_VALUE): Avoid clobbering types by
5580 using == rather than =. Huh... This fixes the dreaded problem
5581 wherein builtin_type_int becomes TYPE_CODE_FLT.
5583 * core.c (info_files): Show the inferior pid.
5585 * config.gdb: Avoid putting "dir" command into .gdbinit. GDB
5586 already knows how to look in the source directory.
5588 * Remove psymtab hair from many places. Remove duplicated code
5589 for searching symbol tables. Hide psymtabs from most places.
5590 Make it fast to get from a psymtab to its symtab.
5592 blockframe.c (blockvector_for_pc): Remove psymtab hair.
5593 coffread.c (psymtab_to_symtab): Rename to psymtab_to_symtab2.
5594 mipsread.c (psymtab_to_symtab): Rename to psymtab_to_symtab2.
5595 dbxread.c: export psymtab_to_symtab, make it work if called N times.
5596 (psymtab_to_symtab): Rename to psymtab_to_symtab2. Initialize
5597 new symtab completely. New psymtabs get symtab pointer
5598 initialized to zero. Remove MI warning printf.
5599 symtab.h: Comments. Add psymtab to symtab pointer.
5600 (PSYMTAB_TO_SYMTAB): New macro.
5601 symtab.c: use PSYMTAB_TO_SYMTAB. Add psymtab_to_symtab and export it.
5602 source.c: use PSYMTAB_TO_SYMTAB. Remove symtab version and
5604 stack.c (backtrace_command): Avoid pre-pass to read symbols, if
5606 (print_frame_info): Avoid special-casing symbols that have not yet
5609 * source.c (open_source_file): Quick path if we have already
5610 located the source file by its full name.
5612 * symtab.c (lookup_symbol): Use find_pc_symtab rather than
5613 find_pc_psymtab. When a name is found in the misc function
5614 vector, search the symbol table for its mangled name, not the
5615 name that the user typed.
5617 * bfd.h: Fix missing comment terminators, make #endifs match.
5619 * valarith.c (value_less): Handle unsigned int comparisons.
5620 Add FIXME about pointer compares, which assume host and target
5621 pointers are the same.
5623 * command.c (do_nothing_command): lint
5624 dbxread.c: lint. Remove sort_syms. Document C++ visibility info,
5625 fix comments on debug symbol format for visibility. Actually set
5626 visibility of symbols.
5627 main.c (echo_command): lint; use <readline/history.h>.
5628 tm-sparc.h (FRAME_FIND_SAVED_REGS): lint
5629 obstack.h (_obstack_blank): Rearrange pointer math to avoid
5630 pointing past end of allocated memory; saber complains.
5631 obstack.h: Declare the external functions that we use.
5632 valarith.h: use <string.h>
5633 solib.c (solib_add): lint.
5635 Fri Sep 21 17:05:19 1990 John Gilmore (gnu at cygint)
5637 * main.c (initialize_main): Default info_verbose to off, now that
5638 symbol reading is fast.
5639 (quit_command): Avoid clobbering exec_bfd while quitting.
5641 * Initial BFD (binary file diddling library) merger:
5642 coffread.c: Change AOUTHDR to struct exe_hdr.
5644 core.c: initialize initialized data at compile time.
5645 (core_file_command): Move from coredep.c, convert to bfd.
5646 (xfer_core_file): Convert to bfd.
5647 exec.c (exec_file_command): use bfd routines.
5649 mips-tdep.c: Remove exec_file_command and friends.
5652 * coredep.c: (fetch_core_registers) Convert core_file_command to
5653 fetch_core_registers.
5654 mips-xdep.c, sparc-xdep.c, sun3-xdep.c: ditto.
5656 * utils.c: (error): Bogus crap, FIXME, to print bfd errors.
5657 (my_bfd_read): More bogosity, which I don't think we call.
5658 (program_name): Remove this atrocity asap!
5660 Wed Sep 19 13:36:41 1990 John Gilmore (gnu at cygint)
5663 values.c: allocate_repeat_value was not clearing the
5664 optimized_out field.
5665 (value_static_field): minor stylistic fix (wrong macro was used).
5666 valops.c (value_struct_elt_for_address): didn't work for C++
5669 * signame.c (_initialize_signame): Initialize signal names once.
5671 * breakpoint.h, command.c, copying.awk, defs.h, environ.c,
5672 exec.c, frame.h, infcmd.c, inferior.h, main.c, munch, sun3-xdep.c,
5673 symtab.h, tm-29k.h, valprint.c, value.h, values.c: Lint.
5675 * remote-eb.c: Support user-settable baud rates on the serial port.
5677 * tm-sun3.h (PREPARE_TO_STORE): fix typo.
5679 Fri Sep 14 13:28:29 1990 John Gilmore (gnu at cygint)
5681 * tconfig/sun3os4: Remove warning about native assembler,
5682 since it also occurs in the xconfig file.
5684 * findvar.c (registers): Allocate some slop after `registers'
5685 to prevent stray accesses from trashing the next variable.
5687 * tm-68k.h (REGISTER_BYTES): Allocate the right number of bytes
5688 on the sun-3, by changing the #ifdef from `sun3' (which is not
5689 defined by cc) to `sun'. Symptom was trashed builtin_type_XXX
5690 vars, which happened to follow `registers' in the executable.
5692 * readline/history.c (history_search): Heed gcc-2's advice
5693 and parenthesize && inside ||).
5695 * am29k-opcode.h, am29k-pinsn.c, am29k-tdep.c, remote-eb.c,
5696 tm-29k.c: Insert FSF copyright headers.
5698 * remote-eb.c: Better comments.
5700 * Makefile.dist: Update to 3.91.6.
5701 * TODO: note PREPARE_TO_STORE problem.
5703 Thu Sep 13 09:52:33 1990 Jim Kingdon (kingdon at cygint)
5705 * stack.c (frame_info): Only use FRAME_FIND_SAVED_REGS if defined.
5707 * remote.c: Wrap the whole file in #if !defined (SPECIAL_REMOTE).
5709 * infrun.c (wait_for_inferior, at end): Don't set up
5710 prev_* if the inferior no longer exists.
5712 * inferior.h (CALL_DUMMY_LOCATION): New macro, to replace
5713 CANNOT_EXECUTE_STACK.
5714 valops.c (call_function): Use it.
5716 * tm-convex.h: Add CALL_DUMMY_LENGTH for use by PC_IN_CALL_DUMMY.
5718 * inferior.h (PC_IN_CALL_DUMMY): New macro.
5719 infrun.c (wait_for_inferior, 2 places): Use it.
5721 * values.c (value_being_returned): Only use
5722 EXTRACT_STRUCT_VALUE_ADDRESS if defined.
5724 * Move PREPARE_TO_STORE from xm-sun3.h to tm-sun3.h to do the
5725 right thing for remote-eb.c.
5727 * sun3-xdep.c: Remove extraneous call to remote_store_registers.
5728 * sun386-xdep.c, hp300hpux-xdep.c, sparc-xdep.c: Ditto.
5730 * blockframe.c: Put get_frame_saved_regs inside #if !defined
5731 (FRAME_FIND_SAVED_REGS).
5733 * findvar.c ({fetch,store}_registers): Check for
5734 REMOTE_{FETCH_STORE}_REGISTER macro.
5736 * findvar.c (get_saved_register): Add argument lval and
5737 change meaning of argument addr.
5738 findvar.c: Change calls to get_saved_register to reflect
5739 new calling convention.
5740 valops.c (value_assign): Use get_saved_register instead of
5741 find_saved_register.
5743 Sun Sep 2 12:40:20 1990 Jim Kingdon (kingdon at cygint.cygnus.com)
5745 * coffread.c (read_one_sym): Make temp_aux an AUXENT, not
5746 an (uninitialized) pointer to one. Use "&" when passing it
5749 Fri Aug 31 22:57:54 1990 Jim Kingdon (kingdon at cygint.cygnus.com)
5751 * coffread.c (getfilename): Use DGUX x_offset and x_name if
5754 * coffread.c (symbol_file_command): Put semicolon after
5756 Put safe_to_init_tdesc_context in #if defined (TDESC).
5757 Put #ifdef TDESCs in 1st column for non-ANSI cpp's.
5758 coffread.c: #include <sys/stat.h>.
5759 (read_coff_symtab): Typo: in_source_files -> in_source_file.
5760 Add missing ')' in check for "lc%" and friends. Remove
5762 Declare read_one_sym() at top of file.
5763 (read_file_hdr): Put in extra #ifdefs so MC68MAGIC and
5764 MC68WRMAGIC can have the same value without causing a duplicate
5767 Thu Sep 13 15:55:36 1990 John Gilmore (gnu at cygint)
5769 * Allow a Makefile to be built without building the
5770 tm and xm file links that screw up builds in subdirectories.
5771 This is done with `config.gdb none', then you can do things
5772 like `make gdb.tar.Z'.
5773 * tconfig/none: Config file for no target system
5774 * xconfig/none: Config file for no host system
5775 * config.gdb: If no TM or XM files are called out by the
5776 host or target file, don't make links for them.
5778 * cplus-dem.c: Add documentation.
5780 * dbxread.c (read_ofile_symtab): Turn a fatal error into a
5781 simple error, so the user's gdb doesn't crash due to some object
5782 file problem (e.g. somebody is rebuilding the file out from under
5785 * printcmd.c (print_address_symbolic): demangle the symbol.
5787 * Makefile.dist (OTHERS): Remove tdesc-lib because it has
5788 Motorola copyrights in it. Make "make gdb.tar.Z" work.
5789 (alldeps.mak): sort and uniq all results from this; duplicates
5790 hose gdb.tar.Z link building. Remove RCS files from
5791 tconfig and xconfig. Add config files for sun386. Add
5792 a few odd files to OTHERS and HFILES.
5794 Mon Sep 10 21:20:24 1990 John Gilmore (gnu at cygint)
5796 * Makefile.dist: Pull solib.c to tconfig/sun?os4.
5797 Roll version number to 3.91.5. Make lint work in bindir.
5799 * README: Document cross-debugging and new file structure.
5801 * blockframe.c: Lint. Include "value.h" to declare read_register.
5802 (find_pc_partial_function): remove duplicate line.
5804 * command.h: Lint. Declare error_no_arg and dont_repeat.
5806 * tm-news.h: Remove inadvertently duplicated stuff.
5808 * mipsread.c: Remove cache_pc_function stuff, now done cleanly.
5809 Clean up usage of misc_function_type. Declare some CORE_ADDRs.
5811 * config.gdb: Allow `config.gdb host target' form. Clean
5812 up previous change that printed bogus messages when you just said
5815 * core.c: #include "command.h" for lint.
5818 * main.c: Remove some casts of enums. Lint.
5825 * printcmd.c (initialize_printcmd): Fix thinko in inspect cmd.
5827 * sparc-tdep.c (isannulled): Take instruction as parameter, don't
5828 read it from memory. This will allow us to save ptrace calls
5829 eventually. Changed caller single_step too.
5831 * sparc-xdep.c (fetch_inferior_registers): Avoid reading regs
5832 that we aren't going to use, saving many ptrace calls, especially
5833 when watchpointing or single stepping. Use some #define's for
5835 (store_inferior_registers): Ditto.
5836 (core_file_command): Use some #define's for constants.
5838 * tm-sparc.h: Add #define's for some register numbers, so we
5839 can eliminate the use of random constants in sparc-xdep.c.
5841 * stack.c (frame_command, print_frame_info, up_command,
5842 down_command) Remove frame_changed, since it
5843 causes a bug and doesn't seem to do anything useful. In some
5844 places it was used as a flag, in others as a stack level (?).
5846 * utils.c: Use MISSING_VPRINTF rather than HAVE_VPRINTF, so the
5847 default is to use the portable (vprintf) version rather than the
5849 * xm-news.h (MISSING_VPRINTF): Add.
5851 * valprint.c (val_print): Demangle fancy vtbl printouts. Lint.
5853 Sat Sep 8 00:24:12 1990 John Gilmore (gnu at cygint)
5855 * Remove stuff that forces -Bstatic linking of gdb, and warnings
5856 about linking debugged programs -Bstatic in the sun?os4 config
5857 files in tconfig and xconfig subdirectories.
5859 * main.c (main): Remove unreached exit(0) now that we exit
5862 * Create TODO file for online bug list. There are too many
5863 "little" bugs to keep track of on paper.
5865 * Change Projects file to refer to bug-gdb@cygnus.com
5866 rather than kingdon@ai.
5868 Fri Sep 7 23:35:15 1990 John Gilmore (gnu at cygint)
5870 * Makefile.dist (VERSION): 3.91.4 now.
5872 * symtab.c (init_misc_bunches): Rename from init_misc_functions.
5873 (condense_misc_bunches): Add sanity check that misc_count is
5874 the same as the number of symbols in the bunch.
5876 * coffread.c: rename init_misc_bunches. Pass an argument
5877 to condense_misc_bunches (a zero).
5879 * dbxread.c (partial_symbol_file_read): Call init_misc_bunches
5880 every time we are called; don't rely on our caller to do it.
5881 (add_file): Remove call to init_misc_bunches.
5883 * mipsread.c: Only warn, don't error, if unknown symbol types.
5884 This keeps an old gdb from falling on its face if it sees newly
5885 extended symbol info. Rename init_misc_bunches.
5887 Fri Sep 7 22:58:15 1990 John Gilmore (gnu at cygint)
5889 * Merge in changes from Per Bothner for DECstations and other
5890 MIPS stuff. The rest is Bothner speaking:
5892 The next message is a merger of Alessando Forin's mips port with
5893 mine. I've tried to use my good if biased judgment to get
5894 the best of both. It *does* need testing.
5896 Some of the changes are general, *not* mips-specific.
5899 Didn't believe in little-endian bit order.
5900 There are still inconsistencies about whether flags
5901 like BITS_BIG_ENDIAN are integer (#if ...) or
5902 boolean (#ifdef ...). I tried to paper over them.
5904 dbxread.c,coffread.c,mipsread.c,symtab.c,symtab.h:
5905 Moved some misc_function code that was common to
5906 {dbx,coff,mips}read.c to symtab.c.
5907 In the process, I think I cleaned things up a bit.
5908 At the same time, moved obsavestring and obconcat to symtab.c.
5911 Removed obsolete condense_addl_misc_bunches (use
5912 condense_misc_bunches(1) instead).
5915 Needed to include <sys/dir>, at least on DECstations.
5917 valops.c, mips-tdep.c, tm-mips.h:
5918 Added PUSH_ARGUMENTS macro to support funny argument-pushing
5919 conventions (when STACK_ALIGN is insufficient).
5920 Needed on mips, where doubles need 8-byte alignment,
5921 but ints only need 4.
5924 Removed cruft that was not being used.
5925 Merged in many fixes (most from Frank Yellin, fy@lucid.com).
5928 Print $ before register-names (I think that makes things a little
5930 Never print two instructions, even if one delays.
5931 Removed hex-disassemble set_cmd. (This is not mips-specific,
5932 so I think the argument is whether it is generally worthwhile or not.
5933 I'm inclined to think not, given how easy it is to
5934 convert between radixes in gdb.)
5937 This is basically Alessando's code.
5938 It doesn't use obstacks; I changed it to use obstacks
5939 in a few minor places where using malloc causes a
5940 memory leak. (Probably, more places could/should be changed.)
5941 I added record_misc_function where it was missing.
5942 In symbol_file_command and add_file_command, I tried
5943 to make the code consistent with more recent versions.
5944 Minor sylistic changes in parse_procedure.
5945 Make a .gdbinfo. psuedo-symbol point back to the real
5946 procedure symbol (using the isym field).
5949 This is basically from my port, but with a lot of details
5950 and a number of routines merged in from Alessando's version.
5951 I basically used my code "raw" backtrace (use heuristics
5952 from the actual code, rather than symbol table info) - though
5953 the idea is Alessandro's. I feel my code is a little cleaner
5954 here, particularly in being a little more flexible, such as being
5955 able to handle gcc-produced code (which it now can).
5956 It also doesn't do frame caching (which is not useful
5957 more recent gdb versions).
5958 I also used my code for push_/pop_dummy, more or less.
5959 I tried to incorporate AF's code for testing sigtramp
5960 while backtracing; I probably got it wrong.
5961 Added mips_print_register, which tries to scrunch as much
5962 information as possible on a screen...
5963 Removed the skip-prologue set_cmd. As with hex-disassemble (see
5964 under mips-pinsn.c), I don't see anything mips-specific here,
5965 and I don't see it being all that useful anyway.
5968 Added a $fp psuedo-reg distinct from $fp (nice for gcc).
5969 Use more register names (rather than hard-cases numbers).
5971 Thu Sep 6 18:33:15 1990 John Gilmore (gnu at cygint)
5973 * Hack up 3.90.11 changes:
5975 * Makefile.dist (depend): parameterize $(GCC).
5976 Add solib.c and solib.o.
5977 (readline): Fix vpath for both absolute or relative SRCDIR.
5979 * blockframe.c: Fix from Schaefer@asc.slb.com for shared libs.
5980 Also, let the part I didn't understand at least compile so
5981 I can test the rest. FIXME.
5983 * dbxread.c: Fix thinko using strcmp.
5984 (init_psymbol_list): declare static.
5985 (partial_symbol_file_open): Comment cleanups better, avoid
5986 cleaning up the string table since the caller will do that.
5987 Move the stat for mod time into symbol_file_command, temporarily.
5988 (There should be a mod time for each symbol file, eventually,
5989 to control its rereading. FIXME.)
5991 * infptrace.c (PT_WRITE_D): use same value as PT_WRITE_I for
5992 SunOS, which gives error for shared libs otherwise. (From
5993 Schaefer, probably FIXME needs work for portability.)
5995 * solib.c: Move #include "param.h" to work.
5996 Lowercase all the Uppercase Letters In the Messages.
5997 (find_solib): Clean up inferior_so_name for debug printouts.
5998 Allow no argument, to mean all shared libraries.
6000 * symmisc.c: include param.h to get CLEAR_SOLIB.
6002 Wed Sep 5 18:00:08 1990 John Gilmore (gnu at cygint)
6004 * Merge in Kingdon's changes from FSF: the diffs from 3.90.9
6005 to 3.90.11. ChangeLog entries below are from this.
6007 Wed Jun 13 09:17:39 1990 Jim Kingdon (kingdon at mole.ai.mit.edu)
6011 * Makefile.dist (HFILES): Add tm-sunos.h.
6013 Tue Jun 12 16:15:26 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
6017 * Makefile.dist (gdb.tar.Z): Change linking of config so it works.
6019 Thu Jun 7 16:22:27 EDT 1990 Jay Fenlason (hack@ai.mit.edu)
6021 * sparc-opcode.h Added single-operand version of rett.
6023 Mon Jun 4 18:12:31 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
6025 * m-sparc.h (REG_STRUCT_HAS_ADDR, STRUCT_ARG_SYM_GARBAGE):
6026 Put parens around gcc_p in expansion.
6028 Thu May 24 15:44:51 1990 Jim Kingdon (kingdon at mole.ai.mit.edu)
6030 * utils.c (lines_to_list): Return 10 if lines_per_page == 0.
6032 Wed May 23 16:36:04 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
6034 * Changes for Sun shared libraries:
6035 blockframe.c (find_pc_partial_function): If a non-text symbol
6036 is found, set *address = pc - FUNCTION_START_OFFSET.
6037 breakpoint.c (insert_breakpoints) [DISABLE_UNSETTABLE_BREAK]:
6038 Disable breakpoints instead of giving an error.
6039 source.c (select_source_symtab): Initialize cs_pst.
6040 symmisc.c: Call CLEAR_SOLIB if defined.
6041 symtab.h: Make text{low,high} CORE_ADDR not int.
6042 (psymtab): New field addr.
6044 dbxread.c: Move DECLARE_FILE_HEADERS outside functions.
6045 (record_misc_function): Give correct type for N_DATA symbols.
6046 (condense_misc_bunches): do "misc_function_count = j" regardless
6048 Take code which is shared between symbol_file_command and
6049 add_file_command and put it into partial_symbol_file_{open,read}.
6050 Split add_file_command into add_file_command and add_file.
6051 Make psymtab_to_symtab read in the string table if the file
6053 Two new parameters to read_dbx_symtab and start_psymtab.
6054 tm-sunos.h: New file.
6056 Tue May 22 17:43:03 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
6058 * infcmd.c: Change cont_command to continue_command and "cont"
6061 Mon May 21 14:41:41 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
6063 * breakpoint.c (enable_breakpoint): Get value of watchpoint.
6065 * defs.h [sparc]: Use <alloca.h> regardless of __GNUC__.
6067 * values.c (USE_STRUCT_CONVENTION): Check for structures of
6068 size 1,2,4,8 rather than size < 8.
6070 * dbxread.c (dbx_lookup_type): Do f->length *= 2 as many times
6071 as necessary, not just once.
6073 * sparc-opcode.h: Add a bunch of new opcodes which Sun as supports.
6075 Thu May 17 15:04:09 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
6077 * {t,x}m-sun386.h, sun386-xdep.c, {x,t}config/sun386
6079 * tm-news.h: Add CALL_DUMMY_*.
6081 * tm-68k.h: Remove duplicate comment at FRAME_FIND_SAVED_REGS.
6083 * config.gdb: In list_host, list_target, use ${i}, not $i.
6085 Tue May 15 21:27:12 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
6087 * source.c (find_source_lines) [BROKEN_LARGE_ALLOCA]: Use xmalloc.
6089 * sparc-opcode.h: Change all store floating-point state register
6090 instructions to have the right match & lose fields.
6092 Sat May 5 12:39:18 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
6094 * Makefile.dist: Move -I${srcdir} to GLOBAL_CFLAGS and pass
6096 config.gdb: If srcdir != ., create readline directory and
6097 copy a makefile into it.
6099 * wait.h, infrun.c: Change WRETCODE to WEXITSTATUS for
6100 consistency with POSIX.
6102 * breakpoint.c (bpstat_stop_status): Disable watchpoint
6103 when we exit its exp_valid_block.
6105 Tue Sep 4 11:46:46 1990 John Gilmore (gnu at cygint)
6107 * Makefile.dist: Bump version to 3.91.3.
6109 * Clean up handling of breakpoint commands (somewhat).
6110 Prompted by Tiemann bug report "cont 10" doesn't work any more.
6112 inferior.h: Add breakpoint_proceeded to inferior status struct
6113 and globals; save it and restore it.
6114 (clear_breakpoint_commands): Cleanup, remove old #define.
6116 infrun.c (clear_proceed_status): Set breakpoint_proceeded.
6117 (save_inferior_status, restore_inferior_status): handle it also.
6118 (proceed): Remove earlier code that set breakpoint_proceeded.
6119 It is now set only in clear_proceed_status.
6120 (clear_proceed_status): Cleanup, use bpstat_clear rather
6121 than clear_breakpoint_commands. No callers need the stop_bpstat
6122 between clear_proceed_status and proceed.
6124 infcmd.c: Add breakpoint_proceeded definition and comment.
6125 (cont_command, jump_command, signal_command): Move call to
6126 clear_proceed_status right next to call to proceed.
6128 breakpoint.c (bpstat_do_actions): Avoid clobbering our
6129 caller's argument while running down the chain of breakpoints.
6130 Use new variable "breakpoint_proceeded" to determine when
6131 a command that it executes moves the inferior past the
6133 (bpstat_clear): Handle NULL argument.
6134 (bpstat_clear_actions): Avoid useless call to
6135 breakpoint_auto_delete.
6136 (delete_breakpoint): Clean up bpstat's that are pointing to
6137 the deleted breakpoint from the stop_bpstat chain.
6138 (breakpoint_auto_delete): Simplify.
6140 * Clean up handling of EOF, error on stdin, etc. This was
6141 prompted by a network problem that caused gdb to go into an
6142 infinite loop filling up its malloc'd memory.
6144 main.c (return_to_top_level): Cleanup: call bpstat_clear_actions,
6145 not clear_breakpoints_commands, which is now gone.
6146 (main): If command_loop returns (e.g. from EOF on stdin), do
6147 a quit_command (looping back to command_loop if quit_command
6148 doesn't really quit).
6149 (command_loop): check result from command_line_input and
6150 exit if it returns NULL, rather than passing the NULL to
6152 (gdb_readline): Free malloc'd result space before returning
6155 * utils.c (query): Handle C-d to mean "yes", just as if the
6156 input was not a terminal. Also avoid infinite loop if EOF
6157 occurs in mid-input-line before newline. This allows
6158 query to be used at EOF on stdin with reasonable results.
6160 * infrun.c (proceed): Set breakpoint_proceeded.
6162 * values.c (value_as_long): Avoid infinite recursion for enums.
6163 (_initialize_values): Fix typo in help msg (kingdon).
6165 * Makefile.dist (RL_LIB): Use RL_LIB_DEP for dependencies,
6166 RL_LIB for linking. This allows -lreadline for linking
6167 and nothing for dependencies, once readline is a real library.
6169 * config.gdb: Jim Kingdon: give useful error message if the
6170 host or target type is not recognized.
6172 * defs.h (alloca): SPARC <alloca.h> does not declare alloca,
6173 it just defines it. Dumb, but deal with it.
6175 * Jim Kingdon suggests:
6176 in xconfig/sun3os4, CFLAGS should be XM_CFLAGS.
6178 Wed Aug 29 18:03:27 1990 John Gilmore (gnu at cygint)
6180 * Makefile.dist (VERSION): Bump version # to 3.91.2.
6182 * Clean up Bothner's changes.
6184 * blockframe.c (clear_pc_function_cache): New function.
6185 * blockframe.c: remake cache_pc_function_* static.
6186 * dbxread.c (symbol_file_command): remove references to
6187 cache_pc_function_* variables.
6188 * dbxread.c (read_struct_type): Use VOFFSET_STATIC.
6189 * printcmd.c: Avoid kludging a global variable (addressprint)
6190 to avoid printing the address of a string twice. Instead,
6191 pass the format letter 's' down low enough that it can be seen
6192 to avoid this problem.
6193 (print_formatted): Pass format arg to value_print.
6194 (restore_addressprint): Remove function.
6195 (do_examine): Avoid hacking addressprint, cleanups and such.
6196 (print_frame_args): Add a comment to a Bothner change.
6197 * symtab.h: define VOFFSET_STATIC and use it instead of "-1".
6198 * symmisc.c (free_all_symtabs): Call clear_pc_function_cache
6199 to wipe out the values cached in blockframe.c.
6200 * symtab.c (find_method): Add comment saying how big you must
6201 allocate to be "big enough". Per being terse again.
6202 * valprint.c (val_print): Handle format letter "s" to print
6203 strings without addresses. Add comment to vtbl printing code
6204 which casts with wild abandon. Rearrange reference-printing
6206 @0xaddr: value (print w/addressprint)
6207 value (print w/~addressprint)
6208 @0xaddr (parameter lists w/addressprint)
6209 or nothing (parameter lists w/o addressprint)
6211 Tue Aug 28 10:47:18 1990 John Gilmore (gnu at cygint)
6213 * Merge more changes from Per Bothner:
6215 Gdb's handling of TYPE_CODE_REF was so counter-C++ (and otherwise
6216 annoying) that I tried to improve it. Here are my suggestions.
6218 These patches all attempt to handle TYPE_CODE_REF (as in C++) better.
6221 Do automatic de-reference when taking the address of a reference.
6223 Don't deref_ref when printing parameter lists.
6225 More attempts at treating refernences properly.
6227 In val_print, if deref_ref==0, don't print dangling " = ".
6229 Add COERCE_REF macro, which de-references an REF.
6231 * Merge changes from Per Bothner:
6233 * Fixed (Sony news)-specific configuration problems.
6234 * Fixed other problems with using vanilla pcc and libc (enum problems;
6235 assumption that vsprintf exists).
6236 * Some major speed-ups (finc_pc_partial_function now caches a match;
6237 parsing avoids duplicate symbol_lookup calls).
6238 * Changed handling of baseclasses (no longer use baseclasses field
6239 of struct type, use the first n_baseclasses fields instead).
6240 * Various minor changes/fixes, most C++-related.
6243 Cache the most previous match from find_pc_partial_function.
6244 (Save both low and high ends of matching function's pc range.)
6245 This speeds up the loop of infrun.c:wait_for_inferior quite
6246 a bit, and makes step/next commands much zippier.
6248 Added an enum->int cast (otherwise, some compilers barf).
6250 No longer set baseclass offset to 0, since multiple
6251 inheritance now mostly works.
6252 Added a number of casts, to shut up compiler warnings
6253 (after stabs where made enums, not ints).
6254 When discarding a symbol table (in symbol_file_command),
6255 must clear the cache introduced in blockframe.c.
6256 Don't convert $vtbl_ptr_type to vtbl any more.
6257 Get rid of TYPE_BASECLASEES and baseclass_vec (see also symtab.h).
6258 Mask off sign bit emitted by g++ for virtual table offset.
6259 Set voffset to -1 (not 1) for static member functions.
6261 Changed parsing/lexing of names to avoid doing symbol lookup twice
6262 (once when lexing to determine symbol class, once for real).
6263 Now only call symbol_lookup once. Fields of 'this' win especially big.
6265 Subpress printing addr twice in the case of 'x/s addr'.
6267 lookup_basetype_type is no longer used.
6268 Add find_methods as recursive helper function to decode_line_1.
6269 This allows multiple inheritance to work.
6270 Also, once one or more matches has been found, do not look in
6271 base-classes. (Baseclass methods would be overridden, anyway.)
6273 Removed baseclasses array in struct type.
6274 Instead of using baseclasses[i], use fields[i-1].
6275 Added virtual_field_bits[i] to indicate if the i'th baseclass is virtual.
6276 Changed sign convention of voffset (previous was inconsistent).
6278 Some macros (CALL_DUMMY and relatives) were missing. Put them back.
6280 Used to assume existence of vsprintf. Re-written to not need it
6281 if HAVE_VPRINTF is undefined.
6283 typecmp was too pessimistic. Made it less so.
6285 Don't print space after address.
6286 If vtable points to a misc symbol (with 0 offset), print it,
6287 since that indicates the actual class of the object.
6288 Changed ype_print_derivation_info to use new inheritance
6289 scheme (without baseclasses vector).
6291 In value_primitive_field, fixed some bugs left over from previous set of fixes.
6292 Also, changes needed because TYPE_BASECLASSES were removed.
6294 REGISTER_U_ADDR didn't work for PC. Rewrote to use an array.
6296 Tue Aug 21 20:08:54 1990 John Gilmore (gnu at cygint)
6299 If there is no path set, and the symbols don't indicate what directory
6300 a file was compiled in, look in the current directory. But either
6301 a path or a known compilation directory will prevent this.
6304 Three independent bug fixes:
6305 * Remove the #if 0 block that breaks some stuff.
6306 * SunOS 4.1 fixed the promoted-parameter-wrong-addr bug in Sun C;
6307 adapt gdb to either SunOS 4.0.* or 4.1.
6308 * MAX_OF_TYPE and MIN_OF_TYPE thinko. By tedg@sun, I think.
6311 Instantiate the class T when looking for methods in it. (Tiemann@sun)
6314 (type_print) Demangle the name being printed.
6315 (type_print_base) Handle botched demangling without coredump (tiemann).
6318 (check_stub_method): Document routine.
6319 (tiemann) fix bug for no-arg functions
6320 Avoid clobbering beyond end of malloc'd storage.
6321 Terminate the argument list properly.
6323 Sat Aug 18 01:29:59 1990 Per Bothner (bothner@cs.wisc.edu)
6325 * Changes merged by John Gilmore:
6328 In breakpoint_1, use new print_address_symbolic instead
6329 of find_pc_partial_function. (This forces use of assembler-level
6330 addresses, and avoids misleading non-mangled source-level names.)
6332 Generalize ansi argument such that -1 means skip arglist totally.
6333 Removed global variable print_ansi_qualifiers (which made
6334 code non-reentrant), in favor of extra explicit arguments
6335 to internal routines.
6337 Add new helper function print_address_symbolic.
6338 Use find_pc_misc_function instead of find_pc_partial_function
6339 (since we want assembler-level symbols here).
6341 Print unknown function as just "f (...)", not "f (...) (...)".
6342 Use new fputs_demangled explicitly.
6344 Fixed a typing violation (problem: value.h cannot be imported
6345 without renaming many variable in this file).
6346 lookup_symbol: If no matching misc_func, look for a C++-mangled name.
6347 decode_line_1: Moved forward some never-reached code.
6348 Made decode_line_2 skip function prologues correctly.
6350 fputs_filtered should not demangle by default.
6351 Add new fputs_demangled to demangle on demand..
6353 Change value_struct_elt to use value_primitive_field (using recursive
6354 utility function search_struct_field). This allows foo.bar to work
6355 for multiple inheritance (so far only for data fields).
6356 Change check_field in the same way (recursive helper function
6357 to support multiple inheritance).
6358 (Note: there are more of these problems that I haven't fixed.
6359 Any code that says TYPE_BASECLASS (t, 1) is probably wrong.)
6360 value_of_this: 'this' symbol name is now just "this", note "$this".
6362 Don't print static members.
6363 Avoid printing "members of <type>" if there are none.
6364 Simplified type_print_derivation_info by merging duplicate code.
6365 Remove useless blank lines in type_print_base (ptype command).
6367 Added declaration of new routine value_primitive_field.
6369 Added value_primitive_field which is generalized version of
6370 value_field that can handle multiple inheritance (non-zero offsets etc).
6371 Re-implemented value_field to call value_primitive_field.
6373 Fri Aug 17 23:33:44 1990 John Gilmore (gnu at cygint)
6375 * infcmd.c -- insert else to avoid 'delete env' coredump when you
6376 delete the whole environment. Karl Berry reported the bug.
6377 * source.c - fix openp to avoid //'s in filenames, which
6378 trigger an Emacs bug causing it to not be able to find files
6379 when running gdb in a window.
6380 * dbxread.c - zap the #if 0 that botches the add-file code.
6381 It seems to work a lot better without all the code commented out.
6383 Fri Jul 20 16:58:46 1990 John Gilmore (gnu at cygnus.com)
6385 * Merge Tiemann's and Ted Goldstein's changes, detailed below,
6388 Tue Jul 17 19:34:33 1990 Ted Goldstein (tedg at golem)
6390 * Makefile - added a ${CFLAGS} to a couple of entries,
6391 added remote-sa.sparc.c
