1 Fri Nov 22 08:27:40 1991 John Gilmore (gnu at cygnus.com)
3 * buildsym.c, coredep.c, mem-break.c, xcoffread.c: Put <stdio.h>
5 * config/mh-i386sco: Override compiler to gcc, print warning.
6 * infptrace.c, language.h, utils.c: Lint.
7 * m2-exp.y: #undef MAX and MIN in case system includes set them.
8 * xm-tahoe.h: Set HOST_BYTE_ORDER. Include system versions of
9 {BIG,LITTLE}_ENDIAN and the INT_MAX family first, to avoid
10 redefinition warnings.
11 * defs.h: Reorder things so that the xm-file gets first crack
12 at #define's, followed by defs.h and then the tm-file.
13 * Makefile.in: Remove spaces after 'ignore exit code' - flags.
14 Late-model BSD 'make's don't cope with them.
16 Thu Nov 21 23:48:56 1991 John Gilmore (gnu at cygnus.com)
18 * Makefile.in: Roll new files into various lists.
20 Thu Nov 21 18:26:11 1991 Fred Fish (fnf at cygnus.com)
22 * dwarfread.c (struct_type): Must initialize the c++ specific
23 portion of union types as well as struct types, since gdb attempts
24 to reference the c++ specific info for both types.
26 Thu Nov 21 10:23:52 1991 John Gilmore (gnu at cygnus.com)
28 * Makefile.in: Roll VERSION to 4.2.90.
30 * defs.h: Incorporate param.h into defs.h. All users changed.
31 * param-no-tm.h: Change users to define TM_FILE_OVERRIDE instead.
32 * param.h, param-no-tm.h: Removed.
33 * Update copyrights in all changed files.
34 * dbxread.c, dwarfread.c, inflow.c, infrun.c, m2-exp.y, putenv.c,
35 solib.c, symtab.h, tm-umax.h, valprint.c: Lint.
36 * tm-convex.h, tm-hp300hpux.h, tm-merlin.h, tm-sparc.h,
37 xm-merlin.h: Avoid host include files in target descriptions.
38 * getpagesize.h: Removed, libiberty copes now.
39 * Makefile.in: Remove getpagesize.h, param.h, param-no-tm.h.
41 * exec.c (exec_files_info): If `verbose' is set, show file offset
44 * main.c: Use getcwd rather than getwd.
45 * standalone.c: Fake getcwd rather than getwd.
46 * xm-*.h: Remove fake values of MAXPATHLEN.
48 * xcoffexec.c: Add /* */ to #if 0'd thing to help ANSI.
50 Wed Nov 20 18:35:56 1991 John Gilmore (gnu at cygnus.com)
52 * Remove gdb/hp-include. Support for HP a.out oddities should be
53 in BFD, not in GDB. Move gdb/hp-include/a.out.h to include/a.out.hp.h.
55 * infptrace.c, tm-sun386.h: Cashier <a.out.gnu.h>, remove refs.
57 * configure.in, xconfig, tconfig, Makefile.in, doc/gdbint.texinfo:
58 Makefile fragments for various hosts and targets now come from
59 gdb/config/mh-* and gdb/config/mt-*. This is for consistency with
62 * rs6000-pinsn.c, rs6k-opcode.h: Clean up.
63 * rs6k-opcode.def: Delete.
65 Wed Nov 20 05:04:40 1991 Fred Fish (fnf at cygnus.com)
67 * dwarfread.c: Recognize obsolete form of AT_element_list
68 attribute still used by at least one AT&T compiler, and possibly
71 Tue Nov 19 07:53:55 1991 Fred Fish (fnf at cygnus.com)
73 * dwarfread.c (enum_type, struct_type): Ignore names invented by
74 helpful compilers for anonymous structs, unions, and enums.
76 * c-exp.y, m2-exp.y: Add defines for yymaxdepth, yy_yys, and
77 yy_yyv, so multiple parsers produced by SVR4 versions of yacc
78 can coexist in the same executable without collision.
80 * symtab.h: Add declaration for lookup_template_type() to kill
81 compiler warnings about conversions from int to pointer.
83 Mon Nov 18 17:45:18 1991 Fred Fish (fnf at cygnus.com)
85 * procfs.c: Move inclusion of defs.h to before param.h, as in
86 all the other source files that include both. This is required
87 to supply some typedefs that are used in files included by param.h.
89 * m68k-tdep.c (m68k_skip_prologue): Add generic m68k support for
90 skipping function prologues, ala the other cpu families (i386,
91 mips, m88k, etc). Add the ability to skip movm and fmovm
92 instructions in the prologues. Still needs support for profile
93 (-p compiled) prologue sequences (FIXME).
95 * tm-68k.h: Change SKIP_PROLOGUE macro to use the new generic
96 m68k prologue skipping function by default.
98 * tm-altos.h, tm-isi.h: Continue to use the old definition of
101 Mon Nov 18 15:12:45 1991 John Gilmore (gnu at cygnus.com)
103 * Makefile.in: Remove tdesc stuff, and extra blanks before colons.
104 * blockframe.c: Remove tdesc-related code. Default
106 * infrun.c: Remove tdesc-related code.
107 * m88k-tdep.c (frame_chain_combine, init_frame_pc): Remove copies
108 of defaultable things.
109 * tm-m88k.h: New file, common to all Moto 88k target configs.
110 Derived from tm-delta88.h.
111 * tm-delta88.h: Use it.
112 * xm-m88k.h: Common file for 88K hosts. Remove obsolete stuff.
113 * xm-delta88.h: Use it.
114 * tm-*.h: Remove FRAME_CHAIN_COMBINE macros, since all are
116 * coffread.c: Remove tdesc stuff.
117 * tconfig/delta88, tconfig/m88k: Remove tdesc stuff.
118 * xconfig/m88k: Rename tm-88k.h to tm-m88k.h.
120 Mon Nov 18 13:51:37 1991 Per Bothner (bothner at cygnus.com)
122 * source.c (open_source_file): If openp fails, try again
123 using just the base (non-directory) part of the filename.
124 This solves various annoying problems, such as when the
125 source was compiled with an absolute pathname - and the
126 source files have moved. Or if the source was compiled
127 using a relative pathname, it can be more convenient
128 to just specific the source directory to the dir command.
130 Mon Nov 18 00:04:41 1991 Fred Fish (fnf at cygnus.com)
132 * cplus-dem.c (munge_function_name): Add missing third arg to
133 instance of call to do_type().
135 * dwarfread.c: Changes to match new dwarf.h. Remove
136 AT_deriv_list, AT_loclist, AT_incomplete, AT_const_data,
139 Sun Nov 17 16:20:53 1991 Michael Tiemann (tiemann at rtl.cygnus.com)
141 * symtab.h (struct type): Moved C++-specific fields into new type
142 `struct cplus_struct_type'. Now takes 10% less memory. Many
144 * symtab.c (init_type): Don't set fields belonging to
145 TYPE_CPLUS_SPECIFIC unless TYPE is TYPE_CODE_STRUCT.
146 * buildsym.c (read_type): Allocate TYPE_CPLUS_SPECIFIC for
148 (read_struct_type): Ditto. Also, add comments about how we can
149 deduce TYPE_VPTR_FIELDNO from inheritance info and fieldname info.
150 * coffread.c (decode_base_type): Allocate TYPE_CPLUS_SPECIFIC for
152 (read_struct_type): Ditto.
153 * dwarfread.c (struct_type): Ditto.
155 * symtab.c (read_range_type): Don't set TYPE_MAIN_VARIANT.
156 (lookup_pointer_type): Don't use or set TYPE_MAIN_VARIANT.
157 (lookup_reference_type): Ditto.

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

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

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

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

282 * buildsym.c: Add hooks for xcoffread.c.
283 * rs6000-pinsn.c, rs6000-tdep.c, rs6000-xdep.c, tm-rs6000.h,
284 xm-rs6000.h, rs6k-opcode.def, rs6k-opcode.h: New files.
285 * xcoffexec.c: New file for handling AIX shared libraries.
287 Mon Nov 11 19:14:31 1991 Fred Fish (fnf at cygnus.com)

290 (and possibly arguments to) the program that generated a core
293 * elfread.c: Remove the register_addr() stub now that it is no
296 * procfs.c: Move misplaced #endif for ATTACH_DETACH. Add new
297 fetch_core_registers() function for core file support.

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

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

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

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

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

397 Thu Nov 7 18:26:15 1991 Steve Chamberlain (sac at rtl.cygnus.com)
399 * Makefile.in: link with libiberty after libreadline, since
400 readline might want something in libiberty.
401 * m88k-xdep.c: Fixed the register offsets in the ptrace_user
402 struct for BCS 88k machines.
403 * xm-m88k.h: don't define USIZE if already defined.
404 * configure.in: Added delta88 target.
406 Thu Nov 7 04:51:19 1991 John Gilmore (gnu at cygnus.com)
408 * am29k-pinsn.c, am29k-opcode.h: Fix decoding of mtacc, dmac, fmac.
410 * tm-*.h: Remove READ_DBX_FORMAT, COFF_FORMAT, and
411 READ_MIPS_FORMAT, which have been unused since BFD. Still
412 remaining is COFF_NO_LONG_FILE_NAMES.
413 * tm-sun3.h, tm-altos.h: Remove detritus accidentally left from
414 function calling code moved to m68k-tdep.c.
416 Wed Nov 6 17:21:59 1991 John Gilmore (gnu at cygnus.com)
418 * coffread.c: Eliminate c_nsyms in favor of c_naux.
419 Complain if no auxents on .bf and .ef FCN symbols, and assume
420 lots of line numbers.
421 (init_linenos, enter_linenos): Use a sentinel at the end of the
422 read-in linenos, to make for a fast, safe loop-end test.
424 Wed Nov 6 02:54:08 1991 Steve Chamberlain (sac at cygnus.com)
426 * coffread.c (read_coff_symtab): coffread used to rely on the
427 x_sym.x_misc.x_lnsz.x_lnno field giving the # of linnos in a
428 function. Two of the formats I'm using (29k and 88k) don't seem to
429 set it. Ths patch to fcn_last_line and (enter_linenos) is an
430 attempt to use the actual size of the linno table in the file to set
431 the number of linenos to process.
433 Tue Nov 5 22:47:46 1991 Steve Chamberlain (sac at cygnus.com)
435 * Makefile.in: put a - infront of the mv y.tab.c c-exp.tab.c and
436 mv y.tab.c m2-exp.tab.c, so that if bison is used, and the files
437 are created in place, so the mv fails, then the make continues.
439 Tue Nov 5 16:47:47 1991 Per Bothner (bothner at cygnus.com)
441 Add C++ as a separate language.
442 * defs.h (enum language): Add language_cplus.
443 * dwarfread.c (end_symtab): Support language_cplus.
444 * c-exp.y: Add new struct language_defn cplus_language_defn.
445 Don't set c to be the default language (see main.c).
446 * c-exp.y (yylex): Only look for field of this if
447 language is C++. (First difference from C!)
448 * language.c: Add case branches for C++ (currently, all
449 the same as C). Also, add c++ to "usage" note for "set lang".
450 * valprint.c (typedef_print). Add case branches for C++.
451 * main.c (main): New way to set initial language: Look at
452 file extension of psymtab containing main(). (Same as we
453 do for symtabs, but avoid loading the symtab yet.)
454 * symtab.c: New routine find_main_psymtab(), used by main()
455 to set initial language.
456 * symfile.c (allocate_symtab): Move code for mapping file
457 extensions-> languages to new deduce_language_from_filename().
459 Fix a C++ problem when looking for methods in super-classes.
460 There was confusion between base and derived types.
461 * valops.c (value_fn_field): Change function interface.
462 * values.c: Use new value_fn_field interface.

467 * utils.c: All the v*fprintf emulation is now in libiberty,
468 so we can get rid of some junk.
469 * xm-sun3os4.h, xm-sun4os4.h, xconfig/decstation, xconfig/i386sco,
470 xconfig/sun3os4, xconfig/sun4os4: Don`t need HAVE_STRSTR any more.
471 * m68k-pinsn.c (print_insn_arg): Support BB/BW/BL
472 type operands, as used by branch instructions.
473 * gmalloc.c: Fix prototype of memcpy.
474 * elfread.c: Comment out register_addr, since it conflicts
475 with the one in coredep.c.
476 * buildsym.h: Remove extern declarations of two functions
477 that are really static in buildsym.c.
478 * tm-mips.h: Add symbolic names for more registers.
479 * mips-xdep.c (store_inferior_registers): Use new register names.
480 * xm-mips.h: Simplify REGISTER_U_ADDR, since it is now
481 only used for core files, not ptrace. Therefore,
482 the KERNEL_U_ADDR hack is no longer needed.
483 The mapping to ptrace number is now in in mips-xdep.c.
484 * mips-xdep.c: Define REGISTER_PTRACE_ADDR (using the
485 mapping from the old REGISTER_U_ADDR), and use it
486 in {fetch,store}_inferior_registers.
487 * mipsread.c: Rename #include ecoff.h to new name coff-mips.h.
488 * mips-tdep.c (mips_push_dummy_frame, mips_pop_frame):
489 Save/restore FP regs correctly (?).
490 * dbxread.c: Remove duplicate define_symbol and type_synonym_name
491 (these had been previously moved to buildsym.c).
492 Hence, define_symbol becomes extern instead of static.
493 * buildsym.c (read_struct_type): Comment out bogus handling
494 of C++ operator methods. Minor hacking of reading of class
495 contexts. Make define_symbol non-static, so dbxread.c can call it.
497 Fri Nov 1 11:05:47 1991 John Gilmore (gnu at cygnus.com)
499 * mipsread.c (read_mips_symtab, read_the_mips_symtab): Use real
500 filename with error messages.
501 * stack.c (frame_select_command): Rename to select_frame_command
502 to avoid "fr" and "fra" having nonunique completions.
503 * symfile.c (sort_symtab_syms): Ignore sort of zero symtab *.
504 (symfile_init): Print file format name when unable to handle it.
505 (free_named_symtabs): Use BLOCKVECTOR rather than obsolete BLOCKLIST.
506 * symmisc.c (free_symtab): Only free linetable if nonzero.
507 * symtab.h: Remove obsolete BLOCKLIST macros.
509 Thu Oct 31 18:12:43 1991 Stu Grossman (grossman at cygnus.com)
511 * infrun.c (wait_for_inferior): another stepi/nexti fix. Ensure
512 that stop_step is 1 at bottom of main loop. I don't know why this
513 needs to be done, but it helps me sleep better at night.
515 Sun Oct 27 18:18:39 1991 Stu Grossman (grossman at cygnus.com)
517 * main.c (initialize_history): Read history after reading all
520 Sun Oct 27 14:09:25 1991 John Gilmore (gnu at cygnus.com)
522 * buildsym.c: Break out initial malloc sizes.
523 (record_line): Record directly in a subfile. Alloc on demand.
524 (compare_line_numbers): Add from xcoffread.c.
525 (end_symtab): New params say whether to sort pendings and
526 linetable. Patch block stabs if defined. Shrink linetable before
527 allocating the symtab.
528 * buildsym.h: Delete line_vector* and prev_line_number. Add
529 global_stabs and file_stabs for xcoffread.
530 * dbxread.c (start_subfile): Move to buildsym. Change above calls.
531 * symtab.h: LINETABLE(symtab) can now be null. Zap LINELIST.
532 * symmisc.c, symtab.c: Cope with null LINETABLEs.
534 * blockframe.c: Pass fromleaf to INIT_EXTRA_FRAME_INFO.
535 * tm-29k.h, tm-88k.h, tm-i960.h, tm-irix3.h, tm-mips.h, tm-pyr.h,
536 tm-sparc.h: Accept fromleaf parameter.
537 * c-exp.y (yyerror): Pass error message if given.
538 * configure.in: Add rs6000 host and target.
539 * inflow.c (new_tty): O_NOCTTY kludge for RS/6000.
540 * symfile.h (entry_point): Add.
542 Sat Oct 26 00:16:32 1991 John Gilmore (gnu at cygus.com)
544 * buildsym.c: New file. Breaks out symbol-table-building routines
545 from dbxread.c, so they can be shared with xcoffread.c.
546 * buildsym.h: New file. Declarations for buildsym.c users.
547 * dbxread.c: Remove large chunks into buildsym.c.
548 * Makefile.in: Add buildsym.c and buildsym.h.
550 * symfile.c (syms_from_bfd): New routine.
551 (add_symbol_file): Call it to do the real work.
552 (syms_from_bfd): Initialize entry_point before calling symfile_init.
553 * symtab.h, symfile.c, coffread.c, mipsread.c, dwarfread.c:
554 Avoid declaring or setting entry_point (symfile.h & symfile.c cope).
556 Fri Oct 25 10:58:16 1991 Mark Eichin (eichin at cygnus.com)
558 * cplus-dem.c (cplus-demangle): added support for templates, static
559 data, and the new (correct) mangling for destructors.
561 * dwarfread.c: (dwarfwarn): created a varargs version of
562 dwarfwarn, for non __STDC__ compilers.
564 * c-exp.y: (yylex): added match for "template" token.
565 (typebase): added TEMPLATE name '<' type '>' clause, for explicit
566 specification of template types.
568 * symtab.c: (lookup_template_type): new function for finding
569 templates in symbol table.
570 (type_name_no_tag): changed to explicitly check for s/u/e at the
571 beginning of the symbol - if it is a template, none of these will
572 be there (but the name will still contain spaces.)
574 Fri Oct 25 18:59:32 1991 Per Bothner (bothner at cygnus.com)
576 Various fixes to improve g++ debugging.
577 * symtab.h: Add is_const and is_volatile flags for each method.
578 These are bit fields - take their space from voffset,
579 which shrinks to 30 bits. Since voffset is now a bitfield,
580 make it unsigned for portability. This changes its interpretation
581 slightly: Static methods now have voffset 1 instead of -1,
582 and virtual offsets start at 2, not 1.
583 * symtab.c: Renamed gdb_mangle_typename to gdb_mangle_name,
584 since it now returns an entire magled method name, not just
585 the type part. This avoids some duplication.
586 It also allows us to correctly mangle const and volatile
587 methods (using the new is_const and is_volatile bit fields
589 * valprint.c (type_print_base), values.c (check_stub_method):
590 Simplify by using new gdb_mangle_name.
591 * values.c (value_headof): Fix to correctly handle single
592 inheritance (actually two fixes, either of which suffices).
593 * dbxread.c (read_struct_type): Handle const and volatile
595 * dbxread.c (read_struct_type): Yet one more place where
596 we must handle '\\' continuations.
597 * valprint.c (vtbl_ptr_name): Add final '\0'.
599 Fri Oct 25 16:06:38 1991 Stu Grossman (grossman at cygnus.com)
601 * tm-sparc.h, tm-68k.h (EXTRACT_RETURN_VALUE): fix output of
602 short return values for sparc and 68k. Patch from Paul Eggert.
604 * coffread.c, coredep.c, i386-xdep.c: install patches for
605 SysV/386 3.2 from Mauro DePalma.
607 Fri Oct 25 02:02:13 1991 John Gilmore (gnu at cygnus.com)
609 * core.c (core_file_info), exec.c (exec_file_info): Print file
610 type. Use printf_filtered.
612 * valops.c (value_fetch_lazy): Avoid 0-length fetches.
614 Thu Oct 24 23:06:40 1991 Fred Fish (fnf at cygnus.com)
616 * dwarfread.c: Add casts to remove compiler warnings.
618 * tm-3b1.h, tm-68k.h, tm-altos.h, tm-amix.h, tm-hp300bsd.h,
619 tm-hp300hpux.h, tm-isi.h, tm-news.h, tm-pn.h, tm-sun2.h,
620 tm-sun3.h: Remove locally duplicated code for calling functions
621 in the inferior. The only differences were in the specific trap
622 vectors used and whether or not an fpu was present. These are
623 now handled by appropriate definitions of BPT_VECTOR and
624 HAVE_68881 respectively. Other minor obvious cleanups.
626 * valops.c: Correct a minor misspelling.
628 * utils.c: Remove local BSD/USG hacks that are now in libiberty.
630 * dwarfread.c: Remove prototype for dwarfwarn. Does not work
633 Thu Oct 24 09:33:44 1991 John Gilmore (gnu at cygnus.com)
635 * stack.c (frame_command): Always print. Use new
636 frame_select_command to select a frame without printing.
638 * dwarfread.c: Use <varargs.h>, since <stdarg.h> is not portable.
640 Thu Oct 24 01:32:51 1991 Fred Fish (fnf at cygnus.com)
642 * dwarfread.c: New file for DWARF debugging format support.
644 * elfread.c: New file for ELF object file format support.
646 * procfs.c: New file for SVR4 /proc (process file system) support.
648 * tm-amix.h, xm-amix.h, tconfig/amix, xconfig/amix: New files for
651 * xm-svr4.h, tm-svr4.h: New files for SVR4 support.
653 * xm-m68k.h: New file for host machines with m68k cpu.
655 * Makefile.in: Add elfread.c and dwarfread.c to SFILES_MAINDIR.
656 Add elfread.o and dwarfread.o to OBS.
658 * symfile.h: Add "elf" to list of supported formats in comment.
660 * c-exp.y, defs.h, symtab.h, valprint.c: Add three new builtin
661 types to gdb, builtin_type_long_double, builtin_type_complex, and
662 builtin_type_double_complex. Add and use new TARGET_SHORT_BIT,
663 TARGET_INT_BIT, TARGET_LONG_BIT, TARGET_FLOAT_BIT,
664 TARGET_DOUBLE_BIT, TARGET_LONG_DOUBLE_BIT, TARGET_COMPLEX_BIT, and
665 TARGET_DOUBLE_COMPLEX_BIT, as the sizes in bits of the indicated
666 types on the target machine (ala the existing TARGET_LONG_LONG_BIT).
668 * infrun.c: When using SVR4 /proc interface instead of ptrace(),
669 call proc_set_exec_trap() to setup child to stop at first instruction.
671 * inftarg.c: When using SVR4 /proc interface, call proc_wait()
674 * m68k-tdep.c: Add new routines supply_gregset(), fill_gregset(),
675 supply_fpregset(), and fill_fpregset(), which are machine
676 dependent support routines for SVR4 /proc interface.
678 * utils.c: Add warning_setup() and warning(). Warning() behaves
679 the same as error() except that it returns normally rather than
680 jumping back to command level. Modules that don't want to call
681 warning() for some reason, but want to produce their own warnings,
682 can call warning_setup() to ensure compatibility with the way
683 warning() and error() deal with the terminal.
685 * symtab.c: Make internal errors produce more useful messages.
687 * tm-68k.h: Move code that is duplicated in almost every single
688 m68k based machine's configuration files to this common file.
689 Duplications in the configuration files still need to be removed
692 * infrun.c (child_create_inferior): System V versions must call
693 setpgrp() with no arguments, to comply with prototyping typically
696 * munch: Add support for SVR4 style nm output.
698 * dbxread.c, mipsread.c symmisc.c, symtab.c: Remove the object
699 file specific fields from the partial symbol table structure and
700 replace them with a pointer to private data for each different
701 flavor of object file reader to initialize appropriately.
703 Wed Oct 23 09:38:20 1991 John Gilmore (gnu at cygnus.com)
705 * xconfig/sun[34]os4: Add note about strstr botch on sunos4.0.3c
708 * mipsread.c (fixup_undef_type): New function. If a struct /
709 union / enum is defined in a header file but nowhere else used,
710 (by typedefing, pointer referencing or declaration) the mipsread code
711 builds the complete tree for the structure but leaves its code as
712 TYPE_CODE_UNDEF as it doesn't know what kind of aggregate it is.
713 Guess its type based on the details of the members.
715 Tue Oct 22 18:04:32 1991 Stu Grossman (grossman at cygnus.com)
717 * infrun.c (wait_for_inferior): Check return value from
720 Mon Oct 21 17:47:03 1991 Stu Grossman (grossman at cygnus.com)
722 * infrun.c (wait_for_inferior): fix stepi/nexti that was broken
723 by my last edit to this routine.
725 Mon Oct 21 14:27:43 1991 John Gilmore (gnu at cygnus.com)
727 * tm-sun3.h (FIX_CALL_DUMMY): problem with cross debugging.
728 FIX_CALL_DUMMY does unaligned accesses and/or forgets to byte swap
729 the values before putting them into the dummy code. (From Peter
732 Mon Oct 21 10:04:39 1991 Steve Chamberlain (steve at rtl.cygnus.com)
734 * configure.in: added ebmon target.
736 Wed Oct 16 22:49:58 1991 John Gilmore (gnu at cygnus.com)
740 * Makefile.in: Roll VERSION to 4.2.
741 * README, TODO, WHATS.NEW: Update.
743 * core.c (core_open): Improve error message for bad file.
744 Pass .reg virtual memory address to fetch_core_registers to help
745 it find the registers in the core-file header.
746 * coredep.c (fetch_core_registers): Take new argument, use it,
747 and pass it to register_addr to locate the block of registers.
748 * xm-mips.h: Update KERNEL_U_ADDR for new scheme. Cleanup a bit.
750 * dbxread.c (read_dbx_symtab, process_one_symbol): Handle
751 Sequent N_FN_SEQ like everybody else's N_FN.
753 * main.c: Circumvent SCO cc bug with #if !!defined(USG).
754 * tm-i386v.h: #endif guck.
755 * xconfig/i386*: Remove -Dgetpagesize()=4096 kludge.
756 * xconfig/i386sco: Add HAVE_STRSTR to avoid ANSI bdeath.
757 * xconfig/tahoe: Add REGEX, which seems to be missing.
759 * coredep.c: Add <sys/types.h> for SCOnix.
760 * dbxread.c (read_dbx_symntab): Avoid coredump on malformed file.
761 * printcmd.c (print_formatted): Flush output before disassembly.
763 Tue Oct 15 20:12:32 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
765 * doc/refcard.tex (sec "Working Files"): consistent metavars and
766 other improvements, due to comments by François Pinard
767 (pinard@iro.umontreal.ca)
769 * doc/gdb.texinfo (appendix "Installing GDB"): changes in
770 configure, and improvenets related to Pinard's refcard comments
772 Tue Oct 15 08:45:12 1991 John Gilmore (gnu at cygnus.com)
774 Changes from Fred Fish:
775 * tm-68k.h (FPI_REGNUM): Add.
776 * infrun.c (child_create_inferior): flush stdout and stderr
778 * configure.in: Handle amigados, amix hosts and targets.
779 * inflow.c: Handle TIOCGLTC_BROKEN for Amiga.
782 * values.c (show_convenience): Use printf_filtered.
783 * main.c (define_command): Check result of lookup_command for
785 (echo_command): Use printf_filtered, and force output out.
787 * dbxread.c (read_enum_type): Avoid Modula-2 kludge that breaks C
789 * i387-tdep.c (double_to_i387): Fix typo for double_to_ieee_extended.
790 * utils.c (_initialize_utils): If !ISATTY, don't paginate.
791 * configure.in, tconfig/decstation, xconfig/decstation: Rename
792 dec3100 to decstation.
794 Mon Oct 14 13:37:50 1991 Roland H. Pesch (pesch at cygnus.com)
796 * doc/gdb.texinfo: Catch up to changes recorded here in ChangeLog
797 (nodes Continuing and Stepping; Memory; Targets) clarifications
800 Fri Oct 11 23:27:06 1991 John Gilmore (gnu at cygnus.com)
802 * tm-{irix3,mips,nindy960,pn,symmetry,vx960}.h: Move
803 REGISTER_U_ADDR to corresponding xm- file. Sugg. by Peter Schauer.
805 * symmisc.c (print_partial_symtabs): Add printpsyms debug cmd.
807 * m68k-tdep.c (m68k_push_dummy_frame, m68k_pop_frame): Add
808 generic routines for calling inferior functions.
810 * blockframe.c (inside_main_scope, inside_entry_scope): New.
812 * copying.awk: Filter formfeeds out of copying & warrantee.
813 Make them available as `show copying' and `show warrantee' also.
814 * main.c (print_gnu_advertisement): Advt `show' commands.
816 Thu Oct 10 17:25:47 1991 John Gilmore (gnu at cygnus.com)
818 * mach386-xdep.c: Even when cross-compiling, leave in the
819 core-file reading code.
820 * core.c (get_core_registers): Avoid coredump if no .reg section.
822 Wed Oct 9 17:03:34 1991 John Gilmore (gnu at cygnus.com)
824 * mipsread.c, coffread.c: initialise TYPE_VPTR_FIELDNO to -1.
825 This avoids coredumps under `set print object on' in value_headof
826 (called erroneously by value_from_vtable_info) for `p &struct'
827 or `p *struct'. From Peter Schauer.
829 Mon Oct 7 00:06:52 1991 John Gilmore (gnu at cygnus.com)
831 * Makefile.in: Roll version to 4.1.2.
832 * dbxread.c: Use aout64.h, not a.out.gnu.h. Get external symbol entry
833 size from BFD (but, FIXME, we don't yet read external nlists's and
834 convert them to internal nlists's before handling them -- we still
835 assume they have the same size and alignment.) Use SET_NAMESTRING
837 * exec.c (exec_file_command): Move dead coff-encapsulation code
839 * m88k-tdep.c, m88k-xdep.c: Remove encap test and #inc <a.out.h>.
841 Fri Oct 4 22:30:06 1991 John Gilmore (gnu at cygnus.com)
843 * configure.in, tm-i386v.h, xm-i386v.h: Intel 386 Mach host port.
844 * xm-i386mach.h, mach386-xdep.c, xconfig/i386mach: New files.
846 Fri Oct 4 17:04:31 1991 Per Bothner (bothner at cygnus.com)
848 More patches from Peter Schauer <pes@regent.e-technik.tu-muenchen.de>:
849 * mips-xdep.c (store_inferior_registers): Don't try to
850 write the (pseudo) FP.
851 * mipsread.c (parse_partial_symbols): Improved algorithm for
852 setting pst->texthigh.
854 Fri Oct 4 16:47:32 1991 Roland H. Pesch (pesch at cygnus.com)
856 * doc/Makefile: make TEXINPUTS include . everywhere
858 Fri Oct 4 00:35:56 1991 John Gilmore (gnu at cygnus.com)
860 * coffread.c, dbxread.c, symfile.c, symmisc.c, symtab.h: Remove
861 vestiges of typevectors, which were for symsegs and are no longer
862 used. (From a question by Eliot Dresselhaus
863 <dresselh@RFT30.nas.nasa.gov>).
865 Thu Oct 3 09:33:26 1991 John Gilmore (gnu at cygnus.com)
867 * dbxread.c, coffread.c: static-ize functions that were
868 gratuitiously external. (From Fred Fish.)
870 * c-exp.y: sym->class to SYMBOL_CLASS (sym).
872 * dbxread.c (dbx_lookup_type): Keep doubling size of typevector
873 until it is large enough.
875 * dbxread.c (read_type): Handle error case slightly better.
876 Make complaint message not C++-specific.
878 Wed Oct 2 17:21:07 1991 Stu Grossman (grossman at cygnus.com)
880 * infrun.c (wait_for_inferior): Fix step/next so that you only
881 stop at the beginning of a new line. This fixes various problems
882 with for loops, nested if-else's and switch statements.
884 Tue Oct 1 06:33:55 1991 John Gilmore (gnu at cygnus.com)
886 * symtab.c (lookup_symtab_1, lookup_symbol): "fatal" errors
887 between symtabs and psymtabs become ordinary error()s.
889 * dbxread.c (read_dbx_symtab): Relocate end_of_text_addr
890 properly, making "end pc" correct in shared lib psymtabs.
891 (From Guy Harris <guy@auspex.com>.)
893 Mon Sep 30 13:15:31 1991 John Gilmore (gnu at cygnus.com)
895 * dbxread.c: Enable, but soften, const_vol_complaint.
896 (read_dbx_symtab): N_STSYM and N_LCSYM define static vars.
897 Ditto Gould N_NBSTS and N_NBLCS. Also, all types in the psymtab
898 should be file-scope, not global.
899 (read_struct_type): Remove ancient multiple-inheritance warning.
900 (read_range_type): Check base type, complain & patch if undefined.
901 * stack.c (frame_info): Demangle the function name in `info stack'.
904 Sat Sep 28 10:02:33 1991 John Gilmore (gnu at cygnus.com)
906 * eval.c (evaluate_subexp_for_address): Don't use
907 TYPE_POINTER_TYPE directly (it might be zero if this type has
908 never had a pointer created before); use lookup_pointer_type.
909 * symtab.c (lookup_method_type): Arguments were swapped in all
910 callers, so fix it here. I'm amazed this worked at all!
912 Fri Sep 27 18:09:31 1991 John Gilmore (gnu at cygnus.com)
914 * c-exp.y, m2-exp.y: Define more yysymbols that happen to be
915 "bss" rather than "data" symbols, but which still conflict.
918 * coffread.c (coff_symfile_read): Use xmalloc, not malloc.
919 * core.c (core_files_info): Shorten output.
920 * exec.c (exec_files_info): Ditto.
921 (build_section_table): Ignore zero-length sections.
922 * language.c, printcmd.c: Lint.
923 * language.h (get_frame_language): Declare.
924 * saber.suppress: update.
925 * stack.c (find_relative_frame): Remove complex code that was
926 #if 0'd, stick with simple code. Lint.
927 * saber.suppress: Update a bit.
928 * symfile.c (add_symbol_file_command): Add "?" to question.
929 * utils.c (parse_escape): Avoid \a due to bdead compilers.
930 * value.h: Declare typedef_print.
932 * valprint.c (val_print, type_print_base): TYPE_CODE_RANGE less
935 * nindy-tdep.c (nindy_frame_chain_valid): Use lookup_misc_func.
936 (Reported by Mark Peek <mark@imagen.com>.)
938 * solib.c (solib_map_sections): Relocate all sections, even
939 though only the text section's size is tracked. Mark ld_text
940 for eventual elimination as we generalize to N sections.
942 * infrun.c (wait_for_inferior): Don't check if the PC is in a
943 call_dummy if we were stopped by a random signal that is being
944 passed to the program. This produced wierd results when calling
945 functions in the inferior and signals (e.g. SIGALRM) were in use.
947 Tue Sep 24 18:05:30 1991 John Gilmore (gnu at cygnus.com)
949 * infrun.c (IN_SIGTRAMP): Not parenthesized properly.
950 Bugfix from Paul Eggert <eggert@twinsun.com>.
951 * tm-ultra3.h (IN_SIGTRAMP): Ditto.
952 * valprint.c (print_floating): Print 9 digits for IEEE floats.
955 Mon Sep 23 15:50:07 1991 John Gilmore (gnu at cygnus.com)
957 * Makefile.in: Roll VERSION to 4.1.1.
958 * source.c (line_info): Peter Schauer fixes a bug I introduced in
961 Fri Sep 20 16:10:52 1991 John Gilmore (gnu at cygnus.com)
965 * Makefile.in (VERSION): Set to 4.1.
966 * language.c (set_language_command): Print useful help message,
967 and restore the language string after giving help.
968 * valprint.c (typedef_print): Print typedef in C or M2.
969 * symtab.c (list_symbols): Use it.
970 * main.c (main): Avoid any output before (gdb) prompt when -q.
971 * language.c (set_language_command): Handle errors by restoring
972 the language string to its current state (fix from A. Beers).
973 * doc/gdbint.texinfo: Roll in information from README. Rearrange
974 "how to install" and "how to print the doc" stuff so it drops
976 * configure.in: Rename rtpc CPU to romp to match config.sub.
977 * README, WHATS.NEW, TODO: Update for gdb-4.1.
979 Fri Sep 20 17:39:14 1991 Roland H. Pesch (pesch at cygnus.com)
981 * doc/gdb.texinfo: Updates from ChangeLog. set/show write,
982 autoloading shared libs, copyright etc on GDB startup, clean up $_
983 and $__ index refs, set/show listsize and related updates to list
984 cmd. New host/target configs.
986 Fri Sep 20 15:46:00 1991 Roland H. Pesch (pesch at cygnus.com)
988 * doc/Makefile: generate aux version-no file doc/gdbVN.m4
989 from main Makefile.in version definition
990 doc/gdb.texinfo: use version recorded in doc/gdbVN.m4 for current
992 Makefile.in (setup-to-dist): generate doc/gdbVN.m4
994 * doc/gdb.texinfo: merge new language-switching and lang-specific
997 Fri Sep 20 15:00:57 1991 Per Bothner (bothner at cygnus.com)
999 * mcheck.c: Add __ONEFILE kludge to allow compilation by non-ANSI
1000 compilers (which may lack stddef.h).
1002 Fri Sep 20 13:29:42 1991 John Gilmore (gnu at cygnus.com)
1004 * dbxread.c (read_dbx_symtab, process_one_symbol): N_FN and
1005 N_WARNING are the same except for the N_EXT bit, so just use their
1006 values alone, rather than OR-ing them with N_EXT.
1008 Fri Sep 20 12:27:55 1991 Stu Grossman (grossman at cygnus.com)
1010 * mipsread.c (parse_lines): Deal with negative extended line
1013 * c-exp.y, m2-exp.y: #define yyerrflag and yynerrs to avoid
1014 global symbol conflicts.
1016 Fri Sep 20 02:28:15 1991 John Gilmore (gnu at cygnus.com)
1018 * .gdbinit: Move 'set complaints' to top, so it runs even in
1019 case we aren't debugging GDB.
1020 * language.c (_initialize_language): Fix type check and range
1021 check documentation strings.
1022 * utils.c (!HAVE_VPRINTF): Define vfprintf as a function, so
1023 language.c can use it. (Though language.c should really not be
1024 handling warnings/errors the way it does, FIXME.)
1025 * symtab.c (lookup_primitive_type): const lint.
1027 Bugfix from Peter Schauer:
1028 * source.c (lines_to_list): Make signed, to avoid comparison
1029 going unsigned and complaining that -3 is too high for 21 lines.
1030 * stack.c (lines_to_list): Ditto.
1032 Thu Sep 19 23:33:41 1991 John Gilmore (gnu at cygnus.com)
1034 * Makefile.in (HFILES): Add minimon.h.
1035 (VERSION): Roll version number to 4.0.95.
1036 (gdb.tar.Z, make-proto-gdb.dir, setup-to-dist, gdb-XXX.tar.Z):
1037 New rules for building distributions. Normal distribution
1038 is built by doing `make -f Makefile.in gdb.tar.Z' in the directory
1039 one level up from here; it calls make-proto-gdb.dir to build a
1040 directory `proto-gdb' which is an image of the release. The old
1041 `gdb.tar.Z' rule still works too.
1042 * config.sub, configure: Roll in latest from ..
1044 Thu Sep 19 17:41:24 1991 Roland H. Pesch (pesch at cygnus.com)
1046 * doc/gdbint.texinfo: Reorder contents; reorganize new-host,
1047 new-target, and new-config chapters; fix minor typos; come closer
1048 to usual GNU markup conventions for @file @samp @code @var.
1050 Thu Sep 19 17:04:12 1991 Per Bothner (bothner at cygnus.com)
1052 Patches from Peter Schauer <pes@regent.e-technik.tu-muenchen.de>:
1053 * mipsread.c (parse_partial_symbols): Enter the name of all
1054 structs/unions... into the psymtab so we can access them if the
1055 symtab is not read in.
1056 * mips-tdep.c: Remove some unneeded #includes.
1057 * xconfig/dec3100: Add HAVE_STRSTR.
1059 Thu Sep 19 15:14:23 1991 John Gilmore (gnu at cygnus.com)
1061 * Makefile.in: Circumvent Sun Make bug on *-exp.tab.o.
1062 * c-exp.y, m2-exp.y: Lint.
1063 * m2-exp.y: Avoid using yytname[] which is a Bison-ism.
1064 * valprint.c (val_print_fields): Check for stub type.
1065 * mipsread.c (_initialize_mipsread): Avoid using
1066 builtin_type_void at initialize time.
1067 (mipscoff_symfile_read): use it now.
1069 Wed Sep 18 15:55:51 1991 John Gilmore (gnu at cygnus.com)
1071 Merge multiple-language support, and partial Modula-2 support,
1072 from Andrew Beers <beers@cs.buffalo.edu>.
1074 * i387-tdep.c: New file, consolidates most 80387 support,

1094 (process_coff_symbol): #if 0'd for functions and params as above.
1095 (read_enum_type): Recognize Modula-2 BOOLEAN.
1096 * symtab.c (add_param_to_type): #if 0'd function to add a

1132 TYPE_CODE_BOOL and TYPE_CODE_CHAR.
1134 * expression.h (enum exp_opcode): Add Modula-2 specific opcodes.
1135 * expprint.c: Look up expression opcodes in language-specific

1168 Tue Sep 17 08:37:41 1991 John Gilmore (gnu at cygint.cygnus.com)
1170 Add Andrew Beers' changes for Modula-2 support. His ChangeLog
1171 entries are enclosed herein. Not all of these changes
1172 have been merged into the master GDB sources -- check the
1173 ChangeLog above here for the merge log.
1175 Mon Jun 3 17:05:45 EDT 1991
1177 m2-exp.y Created. Tested outside of GDB for a few days. Proper
1178 operators were added, C specific operators and tokens
1179 removed. yylex() revamped to some extent. Still things
1180 missing from the grammar, such as sets.
1181 Tested for two weeks in GDB v3.5.
1183 Tue Jun 11 17:23:48 EDT 1991
1185 m2-exp.y Added boolean constants TRUE and FALSE to the grammar
1186 so they are built-in. Sort of a hack.
1188 Fri Jun 14 12:53:51 EDT 1991
1190 m2-exp.y Added range checking for numeric constants. Any numeric
1191 constant is assumed to be of builtin type INTEGER unless:
1192 (1) it is octal or hexadecimal, in which case it is a
1193 CARDINAL; (2) it is too big to fit into an INTEGER, in
1194 which case it is a CARDINAL.
1195 eval.c Added simple range checking for +, -, and * on integers.
1196 Doesn't work very well for *, since 6 * 1,000,000,000 =
1197 1,705,032,704, which fails the simple test of result >=
1198 first_operand, no matter in what order the operands are.
1200 Tue Jun 18 14:11:30 EDT 1991
1202 Broke the parser into parts, one containing the C grammar and the other
1203 containing code to be shared by all of the grammars.
1205 The following files no longer exist:
1210 The following files were added:
1212 c-exp.y (The C grammar)
1213 m2-exp.y (The Modula-2 grammar)
1214 parser-code.c (Code that is shared by the above grammar)
1218 Makefile.dist Changed to reflect the above dependencies. NOTE: It is
1219 now necessary to use the Bison compiler compiler, since it
1220 will generate function/variable prefixes other than yy.
1222 Tue Jun 18 16:47:49 EDT 1991
1224 symtab.[ch] Added the external variable working_lang, than holds the
1225 value of the current working language.
1226 Added the ennumerated type language_mode, with the values
1227 language_auto and language_manual, the former meaning that
1228 GDB sets working_lang as needed, and the latter meaning
1229 that the value of working_lang is totally under user
1231 symtab.[ch] Added the Modula-2 pervasive types INTEGER, CARDINAL,
1232 REAL, BOOLEAN and CHAR. Also added the type codes
1233 TYPE_CODE_BOOL and TYPE_CODE_CHAR.
1234 utils.c Added set_language_command and show_language_command to
1235 implement the GDB support commands "set language" and
1237 expression.h A number of identifiers were added to the type exp_opcode
1238 to facilitate Modula-2 builtin functions, integer
1239 division, and array indexing.
1241 Wed Jun 19 13:25:58 EDT 1991
1243 language.h Added the macro STRICT_TYPE, which evaluates to non-zero
1244 if the language specified by working_lang requires the use
1245 of strict typing of expressions. Eventually, even this
1246 will be able to be changed by the user.
1247 Added the macro RANGE_CHECK, which evaluates to non-zero
1248 if the language specified by working_lang requires the
1249 checking of a value against the domain of its type.
1250 Eventually, even this will be able to be changed by the
1252 language.[ch] Predicates involving types (simple_type, ordered_type,
1253 same_type, integral_type, numeric_type, character_type,
1254 boolean_type, float_type) are added. These predicates are
1255 based on the current value of working_lang, and are handy
1258 Wed Jun 19 15:39:34 EDT 1991
1260 eval.c Added the function type_array_rank which computes the rank
1262 valarith.c Added the funtion value_bool, which when given a integer
1263 value.h value (ie. struct value *) as an argument, it returns a
1264 boolean value (ie. struct value *) true if that integer
1265 is non-zero, and a boolean value false otherwise.
1266 valprint.c Added cases for TYPE_CODE_BOOL, so Modula-2 BOOLEAN values
1267 will print out properly.
1269 Wed Jun 19 16:36:34 EDT 1991
1271 valops.c Added the function value_capitalize, which returns it
1272 value.h argument capitalized if its argument is a lowercase
1273 letter, or the argument unchanged if its argument is not a
1275 valarith.c Added the function range_check_p, which returns non-zero
1276 value.h if its value argument is between the integral bounds upper
1278 Added the function range_check_enum_p, which makes sure
1279 that its value argument is a valid member of the domain of
1281 Added the function range_check_range_p, which makes sure
1282 its value argument lies between the upper and lower bounds
1283 of its type argument, which must be a ranged type.
1284 Added the function check_array_index, which range and type
1285 checks an index of an array.
1286 Added the function value_multi_subscript, which computes
1287 array[idx1,idx2...idxN], given a value array and an array
1288 of values representing indicies.
1289 values.c Changed value_from_long to work with TYPE_CODE_CHAR and
1290 unpack_long to work with TYPE_CODE_BOOL and
1293 Wed Jun 19 18:04:08 EDT 1991
1295 symtab.c Stored pervasive types in a structure and make
1296 lookup_pervasive_type() a lookup function that was based
1297 on working_lang. If lookup_pervasive_type() returned
1298 non-zero, then that value was returned (a fix, since
1299 before it simply wouldn't return the pervasive type.)
1300 language.h Added the macro CAST_IS_CONVERSION, which evaluates to
1301 non-zero if the language specified by working_lang means
1302 "conversion" when it says "cast".
1303 valops.c Added the function value_real_cast(), which performs a
1304 value.h *cast*, not a *conversion*, which is what value_cast()
1305 does when it can. In particular,
1306 value_cast(<float_type>,4) = 4.0, while
1307 value_real_cast(<float_type>,4) = some mess.
1308 eval.c Modula-2 builtin functions implemented: ABS, CAP, CHR,
1309 parser-code.c FLOAT, HIGH, MAX, MIN, ODD, ORD, TRUNC, and VAL.
1310 expression.h Added macros MAX_OF_TYPE and MIN_OF_TYPE to work with MAX
1311 and MIN on integral types. *NOTE*: These are currently
1312 hardcoded to work only if there are 8 bits per storage
1314 eval.c Made logical functions call value_bool to return a
1315 properly typed boolean value, based on working_lang.
1317 Thu Jun 20 11:55:27 EDT 1991
1319 valprint.c Types now print out in a Modula-2 fashion. This works for
1320 the cases when the type is printed out step-by-step, that
1321 is, it doesn't work when the name of a structured type
1322 (which includes the keyword "struct", etc.) is simply
1324 FIXME: Perhaps this is bad. Parts of it seem to kludgey,
1325 since type specifications in C and Modula-2 are very
1326 different. The C printing of a type is very recursive,
1327 whereas in Modula-2 it is generally very simple. C has
1328 type prefixes and suffixes, which have no real analogue in
1329 Modula-2. Maybe type_print() should call a language
1330 specific type printer. This is also advantageous if we
1331 compile GDB to exclude some of the languages. We'll just
1332 leave those functions out.
1334 Thu Jun 20 16:57:10 EDT 1991
1336 dbxread.c When reading the complete symbol table in (via
1337 psymtab_to_symtab()), the number and types of function
1338 arguments are added to a function type. define_symbol()
1339 calls add_param_to_type() to accomplish this.
1340 Assumption: when we come across a function definition
1341 (N_FUN symbol with an 'f' or 'F' in the name), its
1342 arguments will appear before another function definition.
1343 When a function is found, a pointer to its type is placed
1344 in the global in_function_type. Changes that
1345 add_param_to_type() makes are to this global.
1346 valprint.c The type of a function now includes (for Modula-2) the
1347 types of its parameters.
1348 eval.c Type checking and a check for the proper number of
1349 arguments is now done for function calls. Not sure of the
1350 impact this has on C++ member function yet.
1352 Thu Jun 20 19:58:48 EDT 1991
1354 valprint.c Rewrote the type printer. Broke it into two language
1355 specific parts, adding the functions type_print_m2() and
1357 An unfortunate consequence is this: if you debugging a C
1358 program in Modula-2 mode (why?), info types does not work
1359 well with regular expressions, since the types are printed
1360 out in Modula-2 terminology, but stored in C terminology.
1361 language.[ch] Added the functions new_type_last(), type_keyword(), and
1362 type_sep() to aid in the printing of typedefs.
1363 symtab.c Made the printing of typedefs as language independent as
1364 possible through calls to new_type_last(), type_keyword(),
1367 Fri Jun 21 11:50:26 EDT 1991
1369 dbxread.c Check all incoming ennumerated types. If it looks like
1370 Modula-2's BOOLEAN type, then change the type_code of the
1371 type to TYPE_CODE_BOOL so we can process it as a boolean
1373 valprint.c Replaced some of the 0x%x with calls to sprintf and
1374 hexformat() in val_print().
1375 language.[ch] Added the function hex_to_string(), which converts its
1376 integral argument to a hexadecimal number (format is
1377 language based) and returns the result as a string.
1379 Mon Jun 24 12:25:07 EDT 1991
1381 valprint.c Some functions call type_print_1() directly, instead of
1382 value.h using type_print(), so they can specify where (column) to
1383 print things. Since type_print() takes care of language
1384 dependence, that needs to be called first. Added a
1385 parameter depth to type_print() (so it is now like
1386 type_print_1). Changed type_print to type_print_at, and
1387 made type_print a macro that passes a depth argument of
1389 symmisc.c Changed all calls to type_print_1 to calls to
1391 Makefile.dist Made it possible to build GDB for a specific set of
1392 depend languages. Do this by passing a definition for the macro
1393 LANGS to make. LANGS should be a string containing a
1394 space-separated list of language names (ie. LANGS="c m2").
1395 The default is to build all languages. Note that grammar
1396 files must follow the naming convention of <lang>-exp.y.
1397 gdb.lang This holds the current value of the LANGS macro. It is
1398 examined every time make is called, and is updated if
1400 eval.c Added #ifdef _LANG_<lang> to these files.
1401 expread.c Still need to add them to dbxread.c and coffread.c.
1409 Mon Jun 24 16:33:11 EDT 1991
1411 language.[ch] Added the functions hexformat_pre() and
1412 hex_to_string_pre(), which take a prefix argument to
1413 include in the format string. Thus, hexformat_pre("08") will
1414 return "0x08x" (if the working language is language_c).
1415 Made hexformat() and hex_to_string() calls to the above
1416 with "" as the prefix argument.
1418 am29k-pinsn.c, arm-pinsn.c, breakpoint.c, convex-tdep.c, exec.c, core.c,
1419 dbxread.c, i386-pinsn.c, i386-stub.c, i386-xdep.c, i960-pinsn.c,
1420 infcmd.c, inflow.c, m68k-pinsn.c, m68k-stub.c, m88k-pinsn.c,
1421 mips-pinsn.c, mips-tdep.c, ns32k-pinsn.c, printcmd.c, pyr-pinsn.c,
1422 pyr-tdep.c, pyr-xdep.c, remote-vx.c, remote.c, solib.c, source.c,
1423 stack.c, sun386-xdep.c, symfile.c, symm-xdep.c, symmisc.c, tahoe-pinsn.c,
1424 valprint.c, vax-pinsn.c
1426 Changed all occurences of 0x%[0-9]*l*x in printf format strings to
1427 calls to hexformat() and hex_to_string(). Format strings without
1428 the leading "0x" were ignored.
1430 depend Updated to take the above into account.
1433 Tue Jun 25 15:27:18 EDT 1991
1435 symtab.h Added the types range_mode_t, range_check_t, type_mode_t,
1436 and type_check_t to keep track of the current state of
1437 range and type checking.
1438 main.c Added the variables range_mode, range_check, type_mode,
1439 and type_check to record the current state of range and
1440 type checking. Added initialization code to main().
1441 language.h Changed the macros STRICT_TYPE and RANGE_CHECK to examine
1442 the above variables.
1445 Tue Jun 25 17:57:08 EDT 1991
1447 dbxread.c process_one_symbol() updates the variable (enum language)
1448 source_lang based on the extension of the filename
1449 contained in the N_SO sybmol that started this symtab.
1450 When end_symtab() is called, the value of source_lang is
1451 put into the language field.
1452 stack.c select_frame() sets working_lang (and possibly type_check
1453 and range_check) to the language field of the symtab
1454 associated with the frame that is selected if working_mode
1455 is language_auto. If working_mode is language_manual, a
1456 warning is printed and working_lang is not set.
1457 language.c Added the function set_type_range(), which sets the value of
1458 type_check and range_check (if their modes call for
1459 automatic setting) based on the current value of
1460 working_lang. A non-zero argument will cause the current
1461 settings to be output.
1464 Wed Jun 26 14:51:40 EDT 1991
1466 eval.c Added range checks on assignment.
1467 m2-exp.y Added the grammar for sets to the language. Currently,
1468 these do not do anything except print an error message.
1470 Wed Jun 26 17:01:04 EDT 1991
1472 m2-exp.y Added the ability for parse_number() to parse negative
1473 numbers. A global flag is set upon encountering a unary
1474 minus. This was done to make, for example, 1 parse as a
1475 CARDINAL, and not as an integer, per Wirth's examples in
1476 Programming in Modula-2 ed.4.
1477 valprint.c Added support for "set radix 2" by then setting
1478 output_format to 't'.
1479 eval.c Implemented range checking on subrange types. Added calls
1480 to range_check_range_p for BINOP_ASSIGN and BINOP_VAL.
1481 Implemented MIN and MAX for ennumerated types. The
1482 minimum value of an ennumerated type is defined by Wirth
1483 as the first identifier, and the maximum as the last.
1484 m2-exp.y Made octal numbers ending with "B" be characters and those
1485 ending with "C" be numbers, per Wirth's book. (p. 34)
1487 Thu Jun 27 14:11:52 EDT 1991
1489 stack.c select_frame() now only sets working_lang, it does not
1490 notify the user. If working_mode is language_manual, then
1491 a warning is issued once.
1492 main.c At the end of each call to execute_command(), working_lang
1493 is checked against the local static (enum language)
1494 current. If they differ and working_mode is
1495 language_auto, the new settings of language, type and
1496 range checking are printed out.
1497 stack.c Modified frame_info() to include the language of the
1498 current frame in the output of "info frame".
1499 language.[ch] Added the function language_str() which returns the name
1500 of the current language.
1502 Fri Jun 28 15:33:14 EDT 1991
1504 m2-exp.y Added the built-in procedures INC, INCL, DEC, and DECL to
1505 the language. INCL and DECL currently cause an error,
1506 since sets are not implemented yet. INC and DEC are
1507 implemented as PREINCREMENT/PREDECREMENT with one
1508 argument, and as ASSIGN_MODIFY with two arguments.
1509 eval.c Added type checking to the above cases.
1510 value.h Added not_lval_constant to the lval_type ennumerated type.
1511 not_lval_constant means that the value is a constant
1512 value; that is 3 or 'a' or TRUE, not as in a constant
1513 identifier. This is used to help coerce numbers such as 3
1514 to either signed or unsigned numbers.
1515 valops.c Added the function value_coerce_constants() which coerces
1516 constant integers as following: if one is a constant and
1517 the other is not, the constant's type is set to the type
1518 of the other argument. If both are constants and one is
1519 signed, the other is converted to a signed constant.
1521 Sat Jun 29 17:26:29 EDT 1991
1523 valarith.c Added a better range checker. It now checks range
1524 (successfully) on integral operations [+-] (signed and
1525 unsigned) for any C sized type. Still does not work well
1526 for multiplication.)
1527 int_in_size() returns an integer that is coerced to fit into
1528 specified number of bytes.
1530 Mon Jul 1 13:04:14 EDT 1991
1532 language.[ch] Added the function binop_result_type(), which returns the
1533 builtin (struct type *) type that would be the result of a
1534 binop on the two values V1 and V2.
1536 Wed Jul 3 19:22:53 EDT 1991
1538 source.c Extended source_info() to include the source language in
1539 the output from "info source".
1541 Fri Jul 5 13:48:52 EDT 1991
1543 utils.c Moved the support functions for the GDB set/show commands
1544 dealing with language into language.c.
1545 language.c Added the function language_info(), which displays info
1546 about the current working language, type and range check
1547 settings. Called via the GDB command "info language".
1548 Added an initialization routine _initialize_language(),
1549 that sets defaults for the language, type and range
1550 variables and sets up the new GDB commands.
1551 main.c Language setup moved to language.c.
1554 Mon Jul 8 10:10:22 EDT 1991
1556 valarith.c Debugged the range checker for arithmetic. Still does not
1557 work for multiplication very well.
1559 Mon Jul 8 12:40:37 EDT 1991
1561 language.[ch] Added the function value_true() which returns non-zero if
1562 its argument represents a boolean true value.
1563 breakpoint.c Changed breakpoint_cond_eval() to call value_true() to
1564 check the truth of an expression.
1566 Thu Jul 11 12:51:34 EDT 1991
1568 language.[ch] Added the predicate structured_type(), which returns
1569 non-zero if the argument is a structured type.
1570 Added the predicate pointer_type(), which returns non-zero
1571 if the argument is a pointer type.
1572 eval.c Added the ability to do addition and substraction on
1573 pointers and integers. This case simply bypasses the
1576 Thu Jul 11 14:41:42 EDT 1991
1579 Added the symbol N_DEFD (0x4a) which is a definition
1580 module dependency that is used by the GNU Modula-2
1581 compiler and the linker. It is not important to GDB,
1582 except that [dbx|coff|mips]read.c should ignore these
1585 Fri Jul 12 16:07:00 EDT 1991
1587 valprint.c Changed the TYPE_LENGTH(type) >= 0 to TYPE_LENGTH(type) >
1588 0 in val_print(). Also added statements to the else part
1589 to coerce type (argument to val_print) to a pointer type
1590 if it is an "array of unspecified length".
1591 valops.c Added the function value_m2_string(), which returns a
1592 (value) value which is a constant string, whose type is
1593 (ARRAY [0..n] OF CHAR). The length field of the type
1594 structure is set to zero, so it will be interpreted as an
1595 "array of unspecified length".
1596 stack.c Moved the language/frame mismatch check to
1597 main.c:execute_command().
1598 main.c The working language is recorded each time
1599 execute_command() is executed. If working lang has
1600 changed during its execution, then the new
1601 language/type/range info is printed out for the user. If
1602 the working language does not match the language of the
1603 frame, a warning is issued.
1605 Sat Jul 13 16:16:39 EDT 1991
1607 eval.c Moved all the type-checking stuff for operators to
1608 language.[ch] language.c. This is so we can keep language-specific
1609 stuff (like for what type operators are defined) in
1611 language.[ch] Added the function binop_type_check(), which checks to see
1612 if its two (value) arguments are type-compatible with its
1613 opcode argument. The opcode should represent an operation
1614 involving an operator. Also added the macro function
1615 unop_type_check, which calls binop_type_check with a
1616 NULL second argument.
1617 expprint.c Added Modula-2 operators to the op_print_tab, so info
1618 expression.h break works correctly. Also added "op_string", which
1619 returns the string corresponding to the (enum exp_opcode)
1620 opcode that is its argument.
1623 Sat Jul 13 18:26:18 EDT 1991
1625 coffread.c Added code to record the type of function arguments with
1626 each paricular function. Code is very similar to that
1628 dbxread.c Moved add_param_to_type() to symtab.c
1629 symtab.[ch] Added function add_param_to_type() from dbxread.c
1631 *** NOTE: The above additions have not been tested.
1633 Mon Jul 15 12:50:47 EDT 1991
1635 langauge.[ch] Added the functions type_error and range_error, which work
1636 like error() except if the type/range mode is set to
1637 *_mode_warn, then they do not do a return_to_top_level(),
1638 but merely print a warning.
1639 Also changed [set|show]_[type|range]_command() to support
1640 the new "warn" feature.
1642 Thu Jul 18 17:50:54 EDT 1991
1644 mipsread.c Added code to record the type of function arguments with
1645 each particular function. Code is very similar to that
1648 *** NOTE: The above additions have not been tested.
1650 Fri Jul 19 11:19:10 EDT 1991
1652 defs.h Added macros MAX_OF_SIZE, MIN_OF_SIZE, UMAX_OF_SIZE, and
1653 UMIN_OF_SIZE, which when given a size of a numeric type,
1654 return the maximum and minimum value it can hold. UMAX...
1655 and UMIN... return the result for unsigned types.
1656 symtab.h Added the macros MAX_OF_TYPE and MIN_OF_TYPE to operate on
1657 struct types. They call above macros.
1658 dbxread.c Renamed the MAX and MIN_OF_TYPE macros to ..._OF_CTYPE to
1659 avoid a name conlict with the above.
1660 c-exp.y Added range checking on numeric constants in
1661 parse_number() for completeness.
1662 valarith.c Made binop_user_defined_p() and unop_user_defined_p()
1663 return 0 if working_lang is not language_c.
1665 Thu Aug 8 14:17:22 EDT 1991
1669 breakpoint.c Documentation strings of some commands changed to
1670 eliminate the references to the C language where
1673 Tue Aug 13 15:48:03 EDT 1991
1675 m2-exp.y Added qualified identifiers to the grammar. The semantics
1676 are slightly different from those of the GDB operator ::
1678 m2-exp.y Added a rule to each grammar of the form: start ::= exp |
1679 type_exp, where type_exp is any valid type expression.
1681 eval.c Added the opcode OP_TYPE, and an error case in eval.c.
1682 printcmd.c Modified ptype_command() so it actually parses the input
1683 (necessary for type expressions with scope qualifiers).
1684 Added the function ptype_eval() which expects an
1685 expression composed of one OP_TYPE element.
1686 *.[ch] Replaced all occurences of parse_c_expression with
1688 *.[ch] Replaced all occurences of parse_c_1 with parse_exp_1
1690 [End of ChangeLog entries from Andrew Beers for Modula-2 support.]
1692 Mon Sep 16 17:19:46 1991 John Gilmore (gnu at cygnus.com)
1694 Small fixes from Peter Schauer:
1696 * infrun.c (child_attach): Lint.
1697 * solib.c (find_solib): Handle shared libs version 2.
1699 Small fixes from David Wood:
1701 * xm-ultra3.h (SYS_SIGLIST_MISSING): Typo.
1705 * remote-vx.c: Move <stdio.h> to top, for FILE. Fix from
1706 John S <basrai%kanga.dnet@c3po.sm-alc.af.mil>.
1708 * utils.c (wrap_here): Avoid wrap action of fputs_filtered if
1709 chars_per_line is at maximum (user typed `set width 0'). Fix
1710 from Andreas Schwab <schwab@ls5.informatik.uni-dortmund.de>.
1712 Tue Sep 17 17:31:04 1991 Stu Grossman (grossman at cygnus.com)
1714 * coredep.c: include ptrace.h where necessary.
1715 * mipsread.c(parse_lines): fix unsigned char problem that was
1716 messing up line numbers on SGI's and possibly other MIPS based
1718 * infrun.c (child_create_inferior): use better test to check
1719 return val from setpgrp().
1720 * tm-irix3.h, xm-irix3.h, tconfig/irix3, xconfig/irix3: add these
1721 for sgi/irix support.
1723 Wed Sep 18 04:33:31 1991 Per Bothner (bothner at cygnus.com)
1725 * mipsread.c (parse_symbol): Put non-static procedures
1726 in the global block.
1728 Fri Sep 13 00:14:52 1991 John Gilmore (gnu at cygnus.com)
1730 Patch together `text_start' and `text_end' for 29K port.
1732 * exec.c (exec_command): If NEED_TEXT_START_END, define the
1733 variables and set them based on the exec file.
1734 * am29k-tdep.c: declare text_start.
1735 * valops.c (call_function_by_hand): declare text_end.
1737 * inferior.h: Eliminate CANNOT_EXECUTE_STACK in favor of
1738 defining CALL_DUMMY_LOCATION as BEFORE_TEXT_END. This is
1739 because machines that do this will also have to know to
1740 set NEED_TEXT_START_END. Besides, it was a redundant way to
1742 * tm-29k.h, tm-convex.h, tm-np1.h: Eliminate
1743 CANNOT_EXECUTE_STACK, define CALL_DUMMY_LOCATION and
1744 NEED_TEXT_START_END.
1746 Thu Sep 12 00:22:24 1991 John Gilmore (gnu at cygint.cygnus.com)
1748 AMD 29000 changes from David Wood <wood@david.ultra.nyu.edu>:
1750 * Makefile.in (CLIBS): Put XM_CLIBS and TM_CLIBS at end.
1751 Pass MUNCH_DEFINE to munch whenever we run it.
1752 * am29k-pinsn.c (print_insn): Handle NOP specially. Avoid %#x
1753 format string; use 0x%x instead.
1754 * am29k-tdep.c: Use DUMMY_SAVE_GREGS and RETURN_REGNUM.
1755 * ultra-xdep.c, xm-ultra.h: New files for Ultracomputer host system.
1756 * xm-rtbsd.h: New host support for RT/PC running BSD Unix.
1757 * inflow.c: Handle `short' process group IDs.
1758 * infptrace.c (fetch_register): Support CANNOT_FETCH_REGISTER,
1759 and check for ptrace errors.
1760 * coffread.c (SDB_REG_TO_REGNUM): Define if not already.
1761 (coff_symfile_init): Initialize text_bfd_scnum.
1762 (read_coff_symtab): Use it to find the text [and absolute?] sections.
1763 * ../config.sub: Add vendor nyu and os "sym[1-9]*".
1764 * configure.in: Add hosts rtpc-*-* and a29k-*-*.
1765 Merge target arm case with other "easy" cases. Add target
1766 cases a29k-*-none (rehack of am29k), a29k-*-kern (remote to
1767 Ultracomputer kernel), and a29k-*-sym1 (ultracomputer OS's user
1769 * minimon.h, remote-adapt.c, remote-mm.c: Add.
1770 * munch: Cope with RT/PC putting fns in data segment.
1771 Restore ability to override `nm' by specifying MUNCH_NM.
1772 * xconfig/rtbsd, xconfig/ultra3: New host systems.
1773 * tconfig/a29k: Rename from tconfig/am29k. Add remote-mm
1774 and remote-adapt. Remove encapsulated coff #define's (the
1775 support should go in BFD, and gdb shouldn't know or care).
1776 * tconfig/a29k-kern: Same, but for remote kernel debugging.
1777 * tconfig/ultra3: For debugging user processes on Ultra3/Sym1.
1778 * tm-29k.h: Update BADMAG (though it should go away).
1779 Allow the register definitions to be overridden in another
1780 tm-file. Fix SR_REGNUM. Add a mess of _REGNUM's. Separate
1781 RETURN_REGNUM from GR96_REGNUM and DUMMY_SAVE_GREGS from
1782 DUMMY_SAVE_GR96, for handling kernel calling conventions
1783 that use GR64+ rather than GR96+.
1784 * tm-ultra3.h: New file, for use on Ultra3 Unix as well as for
1785 remote debugging of Ultra3 kernel. Includes tm-29k.h and
1786 overrides various things.
1788 * remote-mm.c (mm_attach, mm_wait): Handle attach like
1789 child_attach does, making a clean stop in the newly attached
1791 * remote-eb.c: Lint.
1793 * coffread.c: Make coffread independent of any particular
1794 variant of COFF. Avoid #include-ing any particular one except
1795 internalcoff.h. BFD now passes key values for symbol reading
1796 as part of its coff_data structure (LINESZ, SYMESZ, AUXESZ,
1797 and the symbol masks and shifts); use them.
1798 Remove obsolete end_of_text_addr.
1800 * exec.c: Remove unused include files.
1802 Wed Sep 11 19:38:44 1991 John Gilmore (gnu at cygint.cygnus.com)
1804 * Makefile.in (documentation targets): Pass $(M4).
1805 Bugfix from eggert@twinsun.com (Paul Eggert).
1807 * stack.c (down_silently_command): Check for stack existence.
1809 Tue Sep 10 23:08:29 1991 John Gilmore (gnu at cygint.cygnus.com)
1811 * Makefile.in (VERSION): Update to 4.0.3.
1813 Tue Sep 10 09:19:29 1991 John Gilmore (gnu at cygint.cygnus.com)
1815 * core.c (core_file_command): Print frame at coredump with
1816 its level number, by calling print_stack_frame.
1817 * frame.h: Add selected_frame_level, print_stack_frame.
1818 * frame.h, stack.c: Remove print_sel_frame, print_selected_frame.
1819 * convex-tdep.c, convex-xdep.c, infcmd.c, inflow.c, infrun.c:
1820 Change print_sel_frame and print_selected_frame callers to
1823 * dbxread.c (read_ofile_symtab): Avoid empty else clause.
1824 * symfile.c (free_named_symtabs): Ditto.
1825 * main.c (main): wrap_here needs an arg.
1826 * solib.c (find_solib): Avoid memory access if _DYNAMIC is zero.
1827 (solib_add): Avoid noise.
1828 (solib_create_inferior_hook): Lint.
1829 (sharedlibrary_command): Move dont_repeat to here.
1830 * utils.c (error): Call wrap_here to force buffered output.
1832 Small patches from Peter Schauer:
1834 * coffread.c (start_symtab): Free any existing line_vector before
1836 (read_coff_symtab): Ditto for type_vector.
1838 * source.c (lines_to_list): New variable, replacing function.
1839 (all uses): Use as variable.
1840 (_initialize_source): Add 'set listsize' and 'show listsize'.
1841 * utils.c (lines_to_list): Remove function.
1842 * stack.c (print_frame_info): Use as variable.
1843 * defs.h (lines_to_list): Remove declaration.
1845 Mon Sep 9 13:45:57 1991 John Gilmore (gnu at cygint.cygnus.com)
1847 * breakpoint.c (insert_breakpoints): Restore warning about
1848 the program might be running in another process, but only for
1849 systems with this brain death (#ifdef ONE_PROCESS_WRITETEXT).
1850 * xm-hp300bsd.h, xm-mips.h, xm-vax.h: Define it.
1852 * utils.c (error): if error_pre_print is set, print the string
1854 * main.c (main, print_gnu_advertisement, print_gdb_version):
1855 Reformat legalese so it always prints, but acts as an "I'm here"
1856 message while symbols are being read. If any errors occur,
1857 print a few newlines to set off the message and start it at the
1858 left margin. Remove mention of "help" command, and don't yak
1859 about symbol reading.
1860 (catch_errors): Error string is now printed first in case of
1862 * command.c (undef_cmd_error, lookup_cmd): On undefined command,
1863 suggest the "help" command.
1865 * Makefile.in (VERSION): Set to 4.0.2.
1867 Thu Sep 5 23:49:48 1991 John Gilmore (gnu at cygint.cygnus.com)
1869 * .gdbinit: Remove useless "rr" command. Set complaints
1870 to 1 for people debugging gdb.
1872 * breakpoint.c, remote-vx.c: Reword strings printed by
1873 catch_errors callers.
1875 Wed Sep 4 11:07:50 1991 John Gilmore (gnu at cygint.cygnus.com)
1877 * WHATS.NEW: "history write -> history save". Doc "write on/off".
1878 (Fix from kenc@viewlogic.com.)
1880 Fix some infrastructure to be able to cope with host and target
1881 machines with different sized basic types (ints, ptrs, etc).
1882 (Idea from pierre@la.tce.com (Pierre Willard).)
1884 * values.c (value_from_longest): Rename from value_from_long.
1885 Handle pointer types as well as integers, so that targets with
1886 different pointer sizes from the host can be accomodated.
1887 * breakpoint.c, convex-tdep.c, eval.c, expprint.c, printcmd.c,
1888 valarith.c, valops.c, valprint.c, value.h, values.c: Rename
1889 uses of value_from_long to value_from_longest.
1890 * eval.c, findvar.c, printcmd.c, valarith.c, valops.c: Pass
1891 the correct pointer type to value_from_long{est}.
1893 * doc/gdb.texinfo ($_, $__): Describe types of these variables.
1895 * remote-vx.c: Remove obsolete code for calling functions via
1896 vxworks kludge interface (it referenced value_from_long).
1898 * valops.c (value_string): Find malloc with lookup_misc_func, not
1901 Tue Sep 3 18:37:46 1991 John Gilmore (gnu at cygint.cygnus.com)
1903 Make writing to files work properly. (Fixes to BFD are also needed.)
1905 * core.c (core_open): Open file ourselves, read or r/w, depending on
1906 write_files. Use bfd_fdopenr.
1907 * gdbcore.h (write_files): New variable.
1908 * exec.c (write_files): Define variable, add set&show for it.
1909 (exec_file_command): Use write_files to open for read or r/write.
1911 Make shared library reading happen automatically. These changes
1912 are mostly from Peter Schauer <pes@regent.e-technik.tu-muenchen.de>.
1914 * inferior.h (stop_soon_quietly): Add to exported variables.
1915 * infrun.c (child_create_inferior): call solib hook, if defined.
1916 (child_attach): call solib hook, if defined.
1917 * solib.c: Include inferior.h. Add from_tty to so_list as kludge.
1918 (find_solib): Use lookup_misc_func rather than hand-rolled.
1919 (symbol_add_stub): New stub for catch_errors.
1920 (solib_add): Avoid output if !from_tty. Catch errors rather
1921 than just calling symbol_file_add and bombing.
1922 (solib_create_inferior_hook): Interface with the target process
1923 to let it read and alloc shared libs, then figure out what it did.
1925 * core.c (validate_files): Fix typo, soften warning.
1926 (Fix from Hiroto Kagotani <kagotani@cs.titech.ac.jp>.)
1928 * utils.c (fputs_demangled): Avoid duplicate printing if
1929 demangling is off. (Fix from J.T. Conklin <jtc@cayenne.com>.)
1931 * infrun.c (proceed): Cast -1 to (CORE_ADDR) before comparing.
1932 (Fix from pierre@la.tce.com (Pierre Willard).)
1934 * main.c (catch_errors): Change argument to a char * from an int,
1935 since a char * can point to a struct full of glop, but an int
1936 is not guaranteed to be able to hold a pointer.
1937 * breakpoint.c (breakpoint_cond_eval, bpstat_stop_status,
1938 breakpoint_re_set_one, breakpoint_re_set): Adapt.
1939 * core.c (core_open, solib_add_stub): Adapt.
1940 * remote-vx.c (symbol_stub, add_symbol_stub, callers): Adapt.
1942 Wed Aug 28 18:18:05 1991 John Gilmore (gnu at cygint.cygnus.com)
1944 * Makefile.in: Update VERSION to 4.0.1. Evade GNU Make bug
1945 by adding .NOEXPORT target.
1947 Fri Aug 23 17:14:25 1991 John Gilmore (gnu at cygint.cygnus.com)
1951 * Makefile.in (VERSION): Roll to 4.0.
1952 (gdb.tar.Z): Make refcard.ps as well, for shipment.
1954 Fri Aug 23 14:07:09 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1956 * doc/gdb.texinfo: minor rewordings, crossref to ptype from print,
1959 * doc/Makefile, Makefile.in: generate "gdb-all.texi" rather than
1962 * doc/rdl-apps.texi: renamed from rdl-apps.texinfo
1964 * Makefile.in, doc/Makefile, doc/.Sanitize, doc/gdb.texinfo:
1965 reflect above name change
1967 * WHATS.NEW: correct pointer to refcard.
1969 * doc/gdb.texinfo: update New Features, Installing
1971 * doc/gdbint.texinfo: add short description of configure +template
1973 Fri Aug 23 11:46:08 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1975 * doc/gdb.texinfo: update, fix bugs in "Installing" appendix
1977 Fri Aug 23 01:02:00 1991 John Gilmore (gnu at cygint.cygnus.com)
1979 * Makefile.in: Add config.sub, make doc/rdl-apps.texinfo for
1980 tar file, add dependencies for referenced doc files.
1982 Thu Aug 22 22:17:06 1991 Stu Grossman (grossman at cygint.cygnus.com)
1984 * coffread.c, symfile.c, stack.c: saberized.
1986 Thu Aug 22 16:20:27 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1988 * doc/refcard.tex: permuted Essential Commands sec
1990 * doc/gdb.texinfo: new C++ chapter; revised installation appendix;
1992 set/show symbol-reloading
1993 default set complaints 0
1995 RET-repeat disabled after prompted long displays
1996 processID (attach) interpretation of 2nd GDB cmdline arg
1998 Thu Aug 22 14:05:47 1991 Stu Grossman (grossman at cygint.cygnus.com)
2000 * expread.y, coffread.c, dbxread.c, target.c, mem-break.c,
2001 cplus-dem.c, values.c, valprint.c, symfile.c, remote.c,
2002 breakpoint.c, main.c: lint.
2004 Thu Aug 22 02:02:26 1991 John Gilmore (gnu at cygint.cygnus.com)
2006 Install new configuration scheme for GDB and friends.
2008 * config.sub: Translate ordinary names to three-part names.
2009 * configure: Use three-part names internally.
2010 * configure.in: Translate three-part names to filenames.
2012 * README, WHATS.NEW: Update for gdb-4.0.
2013 * Makefile.in: Roll VERSION to 3.99.
2015 Wed Aug 21 18:21:09 1991 John Gilmore (gnu at cygint.cygnus.com)
2017 * infptrace.c (KERNEL_U_ADDR_BSD): Include a.out.gnu.h.
2018 * i960-tdep.c, m68k-tdep.c, sparc-tdep.c, tm-i960.h,
2019 tm-m68k.h, remote-nindy.c: Change ext_format_XXX structs
2020 to single structures rather than arrays; when passing
2021 their address, use &. This avoids trouble with bdead compilers.
2022 * mcheck.c: Don't include <stdlib.h>; just declare "void abort();"
2023 instead. This avoids portability headaches.
2024 * mips-tdep.c (mips_do_registers_info): Only print FP regs if
2026 * source.c (open_source_file): Avoid ANSI const bdeath by
2027 skipping declaration and then casting result value.
2028 * tm-hp300bsd.h: Clarify comment.
2029 * utils.c (strstr): Result is const char *; ANSI bdeath.
2030 * xm-hp300bsd.h: Define HOST_BYTE_ORDER. Redefine INT_MIN,
2031 since system include file defines it differently from "defs.h",
2032 though the two are equivalent for our purposes.
2033 * tconfig/hp300bsd: Add m68k-tdep.o.
2035 Tue Aug 20 16:01:11 1991 John Gilmore (gnu at cygint.cygnus.com)
2037 * tconfig/sun*4: Remove warnings about system assembler.
2039 Mon Aug 19 13:44:46 1991 John Gilmore (gnu at cygint.cygnus.com)
2041 * mcheck.c: Avoid warning about undeclared abort fn.
2042 * tm-sparc.h (PC_ADJUST): Avoid calling error() from this;
2043 it causes recursive calls to error() when used in cleanups.
2044 To do so requires that we make it a function, so we do.
2045 * sparc-tdep.c (sparc_pc_adjust): New implem of PC_ADJUST.
2046 * utils.c (do_cleanups): Remove the current cleanup from the
2047 chain *before* calling it, in case error() is called from it.
2048 The result won't be pretty, but won't be an infinite loop either.
2050 Mon Aug 19 00:41:04 1991 Michael Tiemann (tiemann at cygint.cygnus.com)
2052 * dbxread.c (read_struct_type): Grok anon structs for C++.
2053 (vb_name, vptr_name): Null terminate these strings.
2055 Fri Aug 16 08:31:03 1991 John Gilmore (gnu at cygint.cygnus.com)
2057 Minor bug fixes from BSD Net2 gdb:
2059 * blockframe.c (get_prev_frame_info): If FRAME_CHAIN_COMBINE
2060 returns 0, there is no previous frame.
2061 * breakpoint.c (commands_command): If !from_tty, don't call
2062 input_from_terminal_p().
2063 * dbxread.c (record_misc_function): Speed up slightly.
2064 (compare_psymbols): Ditto.
2065 * infcmd.c (do_registers_info): Take a second argument to
2066 determine whether to print float registers. "info registers"
2067 does not do so anymore. "info all-registers" does, now.
2068 * mips-tdep.c, pyr-tdep.c (xxx_do_registers_info): Take second
2070 * tm-mips.h, tm-pyr.h (DO_REGISTERS_INFO): Pass second arg.
2071 * inflow.c (initialize_inflow): Set tflags_ours correctly.
2075 * breakpoint.c (bpstat_do_actions): Use a cleanup to restore
2076 executing_breakpoint_commands if we are interrupted by error.
2077 * coffread.c (init_lineno): Avoid problem with zero-sized linetab
2078 versus malloc/free. From: john@labtam.labtam.oz.au (John Carey).
2079 * core.c (solib_add_stub, core_open): Call SOLIB_ADD inside a
2080 catch_errors() so we can setup the frame regardless of whether
2081 the shared libs work.
2082 * ieee-float.c (double_to_ieee_extended): Get exponent from
2083 right place in little-endian systems. From John Carey.
2085 Thu Aug 15 18:43:57 1991 John Gilmore (gnu at cygint.cygnus.com)
2087 * main.c: Remove unused terminating_signals and catch_termination().
2088 (long_options): Terminate with a zero element.
2089 [Bugfix from Atsuo Kawaguchi <atsuo@hark86.harl.hitachi.co.jp>.]
2090 (gdb_readline): Make call-compatible with readline.
2091 (init_signals): Improve comments re vfork vs. signal.
2093 * utils.c (prompt_for_continue): Use new gdb_readline().
2094 If we prompt for continuation, we don't let CR repeat the previous
2095 command, once we get back to a prompt. It's too easy to keep
2096 hitting CR, expecting "--more--" prompts, and have some long
2097 command start repeating on you.
2099 Tue Aug 13 16:17:56 1991 John Gilmore (gnu at cygint.cygnus.com)
2101 * blockframe.c (frameless_look_for_prologue): Speed up by
2102 calling SKIP_PROLOGUE_FRAMELESS_P if it's defined.
2103 * tm-sparc.h (SKIP_PROLOGUE, SKIP_PROLOGUE_FRAMELESS_P):
2104 Define two variants, one faster.
2105 * sparc-tdep.c (sparc_frame_chain): Use target_read_memory
2106 and return zero, rather than giving an error.
2107 (setup_arbitrary_frame): Initialize the PC in the new frame.
2108 (skip_prologue): Add a second arg saying whether we're just
2109 checking for a frameless function or not.
2111 * core.c (core_open, core_close, core_xfer_memory): Move
2112 section table pointers and bfd* into the target_ops.
2113 (core_open): Allow errors in shared lib reading, etc.
2114 (core_files_info): Describe shared library sections.
2116 * exec.c (exec_open, exec_close, exec_xfer_memory, xfer_memory,
2117 exec_files_info, set_section_command): Move section table
2118 pointers and bfd* into the target_ops.
2119 (add_to_section_table): Add BFD to section table.
2121 * target.c (target_xfer_memory, target_info): Pass target to
2122 xfer_memory and target_info functions.
2125 * gdbcore.h: Move struct section_table.
2126 * target.h: New home of struct section_table.
2128 * solib.c (solib_add): New argument is the target_ops whose
2129 section list is to be added to, if any. Reallocate the
2130 sections in that target to add any that come from shared libs.
2131 (throughout) so_sections renamed to sections.
2132 (solib_xfer_memory): Deleted.
2133 * tm-sunos.h (SOLIB_ADD): Add target argument.
2134 (SOLIB_XFER_MEMORY): Delete.
2136 * core.c, exec.c, inftarg.c, remote-eb.c, remote-nindy.c,
2137 remote-vx.c, remote.c, target.c, target.h: Remove add_syms vector
2138 from target_ops. It's the same on all targets. Add two section
2139 pointers to target_ops.
2141 * stack.c (find_relative_frame): Dump ancient algorithm for
2142 "down", just use handy "next" pointers.
2143 (frame_command): Don't error if there is no stack; let user
2146 * inflow.c (new_tty_prefork, new_tty): New prefork routine
2147 modifies static state in the parent process; new_tty itself
2148 runs in the child and modifies the child's file descriptors
2149 to match the saved static state.
2150 * infrun.c (child_create_inferior): Call new_tty_prefork,
2153 * infptrace.c (child_xfer_memory): Add ignored target arg.
2154 * remote-eb.c (eb_xfer_inferior_memory): ''
2155 * remote-nindy.c (nindy_xfer_inferior_memory): ''
2156 * remote-vx.c (vx_xfer_memory): ''
2157 * remote.c (remote_xfer_memory): ''. Rename from
2158 remote_xfer_inferior_memory.
2160 * main.c (main): Only try to attach "corefile" argument if
2161 it starts with a digit.
2163 * symfile.c (symbol_reloading): New "set/show" variable.
2164 (symbol_file_add): Shorten message about symbol reading.
2165 (add_symbol_file_command): Merge with add_syms_addr_command,
2166 since this should work on all targets now.
2167 (stop_whining): Default to zero, to shut up complaints
2168 about bad symbol tables on many systems.
2169 (free_named_symtabs): Just exit unless symbol_reloading.
2171 * xm-sun3os4.h, xm-sun4os4.h: Define BROKEN_LARGE_ALLOCA,
2172 and add comment explaining shared library screw.
2174 * source.c: #if defined => #ifdef.
2176 Thu Aug 8 12:23:19 1991 John Gilmore (gnu at cygint.cygnus.com)
2178 * doc/gdbint.texinfo: Improve doc on porting to new OS's.
2180 Tue Aug 6 17:16:15 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
2182 * doc/rdl-apps.texinfo: provide default readline-appendix finder
2183 (doc/Makefile knows how to make one for local config)
2185 * Makefile.in: use doc/Makefile for doc targets
2187 * doc/Makefile: GDB documentation now has its own Makefile
2188 doc/refcard.tex: renamed from "gdbrc.tex"
2189 doc/.Sanitize: add Makefile; recognize renamed refcard.tex
2190 doc/gdbint.texinfo: add markup in "Cleanups" chapter
2193 Fri Aug 2 00:13:06 1991 John Gilmore (gnu at cygint.cygnus.com)
2195 * values.c (baseclass_addr): When reading target memory, use the
2196 length of the basetype, not the upper type. We've only malloc'd
2197 enough space for the basetype, leading to errors in free().
2199 * expprint.c (print_subexp): Print UNOP_MEMVAL of an OP_LONG that
2200 ends up as a function specially, since we know the actual type of
2201 the pointed-to address. This (somewhat) fixes display of
2202 expressions that include misc_function_vector names. Try `cond 1
2203 !strcmp("a","b")' then `i b'.
2205 * infrun.c: Move DO_DEFERRED_STORES from proceed() to resume().
2206 The child can be proceeded from inside wait_for_inferior in
2207 evaluating breakpoint conditions, and DO_DEFERRED_STORES was
2208 getting skipped in that case.
2210 * expprint.c (print_subexp): Use filtered output, since the
2211 subroutines we call use it, otherwise the output is horribly
2212 mangled, since output of wrappable stuff comes out late.
2214 * Makefile.in: Bump VERSION to 3.98.1
2216 * infrun.c (child_create_process): Use execlp to find the
2217 shell to exec our target program. This requires some fiddling
2218 with `environ' since there is no execlpe().
2220 Thu Aug 1 15:35:17 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
2222 * Makefile.in, doc/gdbrc.tex, doc/rc-* (new files):
2223 Minor rearrangement of refcard permits two new make targets--
2224 gdbrc.dvi DVI output for refcard, using CM fonts
2225 gdbrc.ps PostScript refcard, using PS fonts
2227 Wed Jul 31 16:46:21 1991 John Gilmore (gnu at cygint.cygnus.com)
2231 * TODO, Projects, WHATS.NEW, README: Update for gdb-3.98.
2232 * Makefile.in (gdb-all.texinfo): Avoid touching file if M4 dies.
2234 Wed Jul 31 16:35:58 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
2236 * doc/gdb.texinfo: last changes for release.
2237 Minor typo and formatting fixes; incorporated most fixes remaining from
2238 filed mail commenting on earlier drafts.
2240 Added warnings: pipes don't work in run command;
2241 conditions are converse of assertions;
2242 step over fn without debug info goes to next fn;
2243 vars may have "wrong" values near fn entrance, exit
2245 Added example from Kingston on printing repeated nonadjacent values
2247 Added explicit mention that in Emacs gdb mode C-c and C-z are like
2248 shell mode for signals
2250 Renamed "Stepping and Continuing" to "Continuing and Stepping" so it
2251 doesn't sound so much like its parent "Stopping and Continuing"; also
2252 moved entries on continue to top of section, so they don't get lost.
2254 Improved installation directions in appendix, added manual formatting
2257 Tue Jul 30 17:26:39 1991 John Gilmore (gnu at cygint.cygnus.com)
2259 * configure.in: Remove xm.h and tm.h even if we aren't linking
2260 new ones, so "./configure sun4; ./configure none" does the right
2261 thing. Assume that alldeps.mak and depend are already built in
2262 srcdir, and avoid running "make" (particularly "make depend",
2263 which involves "gcc") from inside configure. Build Makefile
2264 directly rather than building Makefile.conf first.
2265 * configure: Regenerate with above changes.
2266 * Makefile.in: Use $(BISON) to find bison. Roll VERSION
2267 to 3.98. Revise gdb.tar.Z procedure to produce a file
2268 called gdb-$(VERSION).tar.Z but which unpacks into a
2269 directory called "gdb". Move non-source files out of
2270 $(SFILES_SUBDIR). Pretty up alldeps.mak with comments.
2271 (depend): Don't try to do "gcc expread.y".
2272 (expread.o): Update dependencies by hand.
2274 Mon Jul 29 15:21:09 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
2277 Fixed a variety of small typos that prevented info from formatting
2278 cleanly; altered too-long heading for GPL Appendix, as discussed
2279 w/RMS; Changed date on cover to July 91.
2281 Fri Jul 26 13:20:02 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
2284 (1) Applied some fixes due to comments from Larry Breed (easier ones
2285 through chapsec 5.2)
2286 (2) Eliminated use of @footnote---had my doubts about it anyways, and
2287 it's broken in latest texinfo
2288 (3) Introduced *some* use of [] for optional arguments, where
2289 explanation is not simpler by listing cmd w arg and cmd w/out arg
2290 separately. Still not using @deffn.
2291 (4) Dropped in GPL-2. NOTE: one of GPL-2 or texinfo is broken; a
2292 couple of headings are too long. Need patches to texinfo or revision
2295 * Partial update to README (which still needs work for this
2296 release!): (1) use of configure corrected for new script,
2297 (2) "make gdb.dvi" and "make gdb.info" mentioned.
2299 Wed Jul 24 06:44:02 1991 John Gilmore (gnu at cygint.cygnus.com)
2301 * symtab.c (lookup_symbol): Don't complain right off about
2302 no debug symbols; use the misc function vector first.
2303 (list_symbols): Use misc function vector to find symbols
2304 that don't have debug info, and print them.
2305 (find_pc_symtab): Temporarily avoid fatal() when psymtab
2306 PC range doesn't match symtab PC range, as it does on the
2307 MIPS because our symtab reading isn't perfect.
2309 * dbxread.c (dbx_symfile_read): Make warning about
2310 "no debug symbols" slightly nicer.
2312 * source.c (select_source_symtab): If "main" symbol exists,
2313 but decode_line_spec can't find line info, don't just return
2314 a zero; try other source symtabs or give an error.
2316 * mipsread.c (parse_partial_symbols): Sort the psymtabs by
2317 their low addresses first, then rip through fixing high addrs.
2319 * ns32k-opcode.h (sfsr): Bugfix from Rune Nerg}rd,
2320 <runene@ifi.uio.no>.
2321 (NS32K_SVC_IMMED_OPERANDS): Reverse the #ifndef.
2323 Tue Jul 23 18:52:43 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
2325 * Minor, mostly mechanical, cleanup of doc subdir for clean
2326 makeinfo'ing and TeXing; also ensured gdb-all.texinfo (post-m4)
2327 and gdb.info (post- texinfo2 makeinfo) generated for distribution.
2329 Sun Jul 21 03:54:52 1991 John Gilmore (gnu at cygint.cygnus.com)
2331 Mostly MIPS and general symbol-reading fixups.
2333 * doc/gdbint.texinfo: Add documentation on symbol-reading
2336 * mipsread.c: Remove kludges around #include "ecoff.h".
2337 Remove redefinitions of a_magic, etc, no longer used.
2338 (parse_symbol, ): Convert "Internal:" printfs to complain()ts.
2339 Fix global overview comments to match symfile.c protocol.
2340 (mipscoff_new_init): Eliminate cur_hdr if we have one.
2341 (mipscoff_symfile_read): Eliminate unused code. Avoid
2342 sorting all the symtabs, when all we have read here is psymtabs.
2343 The symtabs are sorted as they are created anyway. Tell
2344 condense_misc_bunches whether we're mainline.
2345 (psymtab_to_symtab_1): Pass filename when recursing, to make
2346 stack trace more informative.
2347 (parse_partial_symbols): Assume cur_hdr as argument.
2348 (read_mips_symtab): Don't clobber cur_hdr, so it can be freed.
2349 Pass cur_hdr implicitly to parse_partial_symbols. Avoid checking
2350 the TYPE_NAME of char *, since that's done in symfile.c.
2351 (free_numargs, parse_symbol, add_symbol, add_block,
2352 shrink_linetable): Declare these fns void.
2353 (upgrade_type): Convert tree of if's to switch. Clean up
2354 bogus "off == 0" handling with a complaint. Avoid setting
2355 field bitpos and bitsize of array with lower and upper bounds.
2356 Check specified bitsize of elements against their actual type's
2357 bitsize, and complain if different. Complain about unknown
2359 (parse_fdr): Don't assume sizeof(char *) == sizeof (struct *).
2360 (psymtab_to_symtab_1): Print names of subsidiary files that
2361 are being read in. FIXME, we read far too many files. This code
2362 is not the problem, the problem is in parse_fdr where the psymtabs
2364 (cross_ref): Result should indicate that we used one aux entry
2365 normally, or two if we encountered a "next" entry. This used
2366 to leave the caller pointing at the wrong aux entry.
2367 (add_symbol): If overflowed cur_block, reallocate it larger,
2368 chase all pointers to it, and complain(), rather than clobber memory.
2369 (shrink_block): Use xrealloc rather than xmalloc-and-copy.
2370 (new_field): Only allocate one field initially, not two.
2371 Pull ++ out of macro argument. Simplify.
2372 (_initialize_mipsread): Avoid initialization of importd
2373 global_psymbols and static_psymbols.
2375 * symfile.c (psymtab_to_symtab): Depend on XXX_psymtab_to_symtab
2376 to properly set pst->symtab; avoid searching for it.
2377 (symfile_fns): Improve comments, add a FIXME.
2378 * dbxread.c: Update comments to reflect symfile protocol.
2379 (read_ofile_symtab, end_symtab): Return the symtab.
2380 (psymtab_to_symtab_1): Set pst->symtab.
2382 * coffread.c (coff_symfile_read): tell condense_misc_bunches
2383 whether we're mainline.
2385 * symfile.h (sym_fns): Remove unused sym_discard member.
2386 * coffread.c, mipsread.c, dbxread.c: Remove XXX_symfile_discard.
2388 * mtrace.c (mtrace): Take effect if mallwatch is set, even if
2389 the environment variable is not.
2390 * infcmd.c (finish_command): Use filtered printfs.
2391 * cplus-dem.c: Add struct tags to a few unnamed structs.
2392 * valops.c (value_coerce_array): Improve comments.
2393 * valprint.c (type_print_varspec_suffix): Print array size only
2394 if greater than zero.
2395 * m88k-tdep.c: Shift some lines left by one space, that had
2396 apparently been trashed at some point.
2397 * TODO: More things to do, a few got done.
2399 Thu Jul 18 22:46:05 1991 John Gilmore (gnu at cygint.cygnus.com)
2401 * symtab.h (LOC_EXTERNAL): Eliminate in favor of LOC_STATIC.
2402 (ldsymoff, ldsymlen, globals_offset, statics_offset): Improve
2404 * dbxread.c (read_dbx_symtab): LOC_EXTERNAL -> LOC_STATIC.
2405 * expread.y, findvar.c, symmisc.c: Ditto.
2406 * printcmd.c (address_info): Update printed forms of LOC_
2407 symbols. Elim LOC_EXTERNAL.
2408 (print_frame_args): Keep track of param stack offsets before
2409 re-looking up to find the local register param is kept in.
2411 * mipsread.c: Use <symconst.h> and <sym.h> rather than <syms.h>.
2412 Further integration of mipsread into gdb. Eliminate unused
2413 routines, duplicate declarations. Handle static symbols in
2414 psymtabs as well as external symbols. When reading symtabs,
2415 insert symbols into the correct block (global, static, or a local
2417 (read_mips_symtab, parse_partial_symbols): Don't pass useless
2419 (mipscoff_symfile_read): Don't call select_source_symtab.
2420 (parse_symbol): Use SYMBOL_VALUE_ADDRESS where appropriate,
2421 rather than SYMBOL_VALUE.
2422 (parse_external): Comment clobbering of top_stack.
2423 (parse_partial_symbols): Update comments. Allocate and parse
2424 static symbols as well as external symbols. FIXME, enum values
2425 are not handled in this pass, but should be. Inline new_psymbol.
2426 Use SYMBOL_VALUE_ADDRESS.
2427 (psymtab_to_symtab_1): Read symbols into global static block
2428 by default (until enter some function's local block context).
2429 (sort_blocks): Clean up STATIC_BLOCK as well as GLOBAL_BLOCK.
2430 (destroy_all_symtabs, new_psymbol): Eliminate, unused.
2432 * source.c (select_source_symtab): Select a source symtab
2433 from either the symtabs or, failing that, the psymtabs.
2434 (list_command): Update error message.
2435 (forward_search_command, reverse_search_command): Use getc, not
2436 fgetc, for speed. FIXME, add comment about buffers that die if
2437 overrun by long line.
2439 * values.c (unpack_field_as_long, modify_field): Avoid shifting
2440 by an entire word, which is not portable, if we have a 32-bit
2441 field. (Code in dbxread.c already turns such bitfields, if
2442 aligned, into ordinary ints, but fixing this will help for other
2443 symbol formats and for future changes.)
2444 * core.c (core_open): Handle ANSI const brain death.
2445 * utils.c (vprintf): Fix varargs typo.
2447 Sun Jul 14 00:42:53 1991 John Gilmore (gnu at cygint.cygnus.com)
2449 * findvar.c (find_var_value): Handle &function better.
2450 * TODO: Document work needed on &fn and &array.
2451 * printcmd.c (print_address_symbolic): New arg is the prefix
2452 to print if a name is printed.
2453 (print_address_demangle): Honor "set print address" now.
2454 Use new arg above to improve spacing of output.
2455 * valprint.c (val_print): When printing function pointers,
2456 print symbolic form too.
2457 * breakpoint.c (breakpoint_1): Use new print_address_symbolic.
2459 Mon Jul 8 19:02:46 1991 John Gilmore (gnu at cygint.cygnus.com)
2461 * core.c (memory_error): Reword error msg to mislead less.
2463 * mips-pinsn.c (print_insn_arg 'd'): Print $ with reg name.
2465 * mipsread.c (read_mips_symtab, read_the_mips_symtab,
2466 parse_partial_symbols): Use newer BFD internals (external_filehdr
2467 and external_aouthdr), byte-swap the fields that we care about
2468 before using them, and make the file header data local to
2469 read_the_mips_symtab rather than global.
2471 Sat Jul 6 01:34:15 1991 John Gilmore (gnu at cygint.cygnus.com)
2473 * ns32k-opcode.h (movmw, movmd): Fix opcodes. Bug fix
2474 from Rune Nerg}rd <runene@ifi.uio.no> on 5 Jul 1991.
2476 * main.c (command_line_input): Flush stdout and stderr
2477 before every call to readline. This reportedly fixes a bug
2478 that comes up in Sys V running emacs-gdb and/or xxgdb,
2479 when stdin/out are pipes or sockets.
2481 Thu Jul 4 14:47:06 1991 John Gilmore (gnu at cygint.cygnus.com)
2483 * configure.in, Makefile.in: Avoid rebuilding "depend" as much.
2484 Avoid declaring Makefile dependencies, because GNU Make stupidly
2485 tries to update it if we do.
2487 * coffread.c: Revise for minor changes to bfd internal coff
2490 * configure: If -template= is given a relative path, make it
2491 absolute before recurring in subdirectories.
2493 * configure, configure.in, Makefile.in: Install "configure" script
2494 as replacement for config.gdb.
2495 * config.gdb, Makefile.dist, Makefile.sdir: Remove
2496 * README: Update for configure, mostly. FIXME.
2498 * Add dec3100 as equivalent to littlemips. Indicate in all host &
2499 target config files that they are for the host. When the lines
2500 get copied into the Makefile, this makes it more obvious what's
2503 Mon Jun 24 23:49:07 1991 John Gilmore (gnu at cygint.cygnus.com)
2505 * sparc-opcode.h (trap opcodes): Avoid leading spaces or
2506 tabs, which end up in the disassembler output inadvertently.
2508 Wed May 29 23:01:03 1991 John Gilmore (gnu at cygint.cygnus.com)
2510 Make it compile cleanly in an ANSI GCC2 environment.
2512 * blockframe.c: <stdio.h>
2513 * cplus-dem.c: free takes a void *, ifdef __STDC__
2514 * dbxread.c (read_huge_number): avoid gcc2 bug hoisting calc of
2516 * defs.h (alloca): Avoid doing anything if alloca already def'd.
2517 * stddef.h, stdlib.h: Remove these files.
2518 * symtab.c: Avoid declaring qsort, close.
2519 * symfile.c: Avoid declaring close.
2520 * utils.c (vprintf): Declare "ap" arg as proper va_alist.
2521 * sparc-tdep.c: Avoid including lots of Sun-host-specific files.
2523 Assorted other changes.
2524 * dbxread.c: include "libaout.h", not "liba.out.h".
2525 * printcmd.c (print_frame_args): Set recurse properly for
2526 indentation of struct and array parameters.
2527 * valops.c (value_cast): Allow cast to void.
2528 * infrun.c (resume): If NO_SINGLE_STEP, call machine dependent
2529 single_step() in a target-independent fashion.
2530 * sparc-tdep.c (single_step): Don't call ptrace ourselves, just
2531 set up to be ready to continue. This makes us target independent.
2532 * infptrace.c (child_resume): Remove call to single_step; now
2533 can single step a SPARC target of any kind.
2535 Wed May 22 18:18:24 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
2537 * Makefile.dist, doc/gdb.texinfo, doc/*-m4.texinfo: split up GDB
2538 docn into separate sections---basically chapters, plus two loose
2539 pieces that can be configured to go in different places. This
2540 allows GNU m4 to preprocess the manual without coredumping.
2542 * Makefile.dist: tell TeX where to find texinfo.
2544 Mon May 20 12:15:04 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
2546 * Makefile.dist, doc/gdb.texinfo: respectively create, and use,
2547 the new target "rdl-apps.texinfo" which captures the Makefile
2548 variable that records where to find the Readline libraries.
2550 Sun May 19 05:36:59 1991 John Gilmore (gnu at cygint.cygnus.com)
2552 * tahoe-pinsn.c: #include "tahoe-opcode.h", not "opcode.h".
2553 * tm-tahoe.h (FIX_CALL_DUMMY): Ignore more parameters.
2554 * defs.h (const, volatile): Only define if not already defined.
2555 * Makefile.dist (gdb.tar.Z): Create doc subdir w/out CVS/RCS crud.
2557 * README: Update for release 3.95.
2558 * config.gdb: Don't create readline dir in subdir builds.
2559 * main.c: Include with "..." form for non-system include files,
2560 so "gcc -MM" for "make depend" works.
2561 Include readline files with "...h" rather than <readline/...h>.
2562 * mipsread.c: Include "ecoff.h" rather than "intel-coff.h".
2564 * coffread.c: Undo minor damage done by Rich Pixley. Use
2565 different internal and external representations of COFF
2566 data structures. Use new BFD routines for swapping them in and
2568 * symfile.c (free_named_symtabs): Avoid freeing file names that
2569 are null or empty. Old i960 tools seem to produce files that
2570 claim to have empty names, causing each successive file read
2571 to blow away the previous one.
2572 * sparc-xdep.c (deferred_stores): Repair minor damage by Rich.
2573 Move deferred_stores to top of file, but don't separate its
2574 #define's from its variable. Add commentary.
2575 * Makefile.dist: Fix Rich damage; undo "configure" changes in
2576 favor of keeping the (working) config.gdb. Move readline
2579 Fri May 17 12:49:56 1991 Per Bothner (via gnu at cygint.cygnus.com)
2581 * dbxread.c (read_struct_type): Try to handle g++ version 1 MI
2583 * infptrace.c (fetch_registers): no result, since now void.
2584 * tconfig/news: target depends on m68k-tdep too.
2586 Fri May 17 14:40:14 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
2588 * Makefile.dist: added readline/inc-*.texinfo to dependencies for
2591 * readline/inc-history.texinfo, readline/inc-readline.texinfo:
2592 applied various small fixes due to or inspired by RMS comments
2594 * doc/gdb.texinfo: finished using all RMS comments, save those for
2595 appendices on readline and cmd history (which are in other source
2598 Thu May 16 18:06:05 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
2600 * doc/gdb.texinfo: (1) Updated w/ref to RMS comments through
2601 chapter 9; (2) documented 'break' command's menu mode for
2602 overloaded names, in response to hgs problem report C++ p-31
2604 Wed May 15 11:02:48 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
2606 * doc/gdb.texinfo: (1) better introductory example; (2) more
2607 consistent use of @code, @samp, @file, @kbd throughout; small
2608 cleanups to first three nodes; (3) new "Contributors" node;
2609 (4) Appendix, Renamed Commands; (5) divert specialized startup
2610 instructions to "Targets" chapter for generic manuals, while
2611 leaving them up front for manuals specific to specialized
2612 environments; (6) apply fixes from RMS comments through chapter 4.
2614 * pretex.m4: modify explanatory text slightly (and redefine
2615 "regexp") to keep GNU m4 from complaining. (It still crashes
2616 later, but one step at a time...)
2618 Wed May 15 10:32:12 1991 John Gilmore (gnu at cygint.cygnus.com)
2620 * readline/readline.c (update_line): Avoid dereferencing a pointer
2621 before comparing it to its bounds. Saber caught this.
2622 (init_terminal_io): Don't set BC from the "pc=" termcap variable,
2623 and only set PC if tgetstr returned non-null. Saber caught this.
2625 Tue May 14 16:29:53 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)
2627 * Makefile.dist: put gdb.dvi stuff (updated to use M4 preprocessor
2628 stuff for config manual) here where it counts; updated
2629 to use new subdir structure (gdb/doc/).
2631 * Makefile: generated from above via
2635 * gdbint.texinfo: added instructions on generating gdb.info* files
2636 locally for release. These are ordinary info
2637 files, formatted from gdb.texinfo (via gdb-all.texinfo, see
2638 Makefile)---but due to use of texinfo 2, can't count on makeinfo
2639 to generate these, so we distribute them already formatted.
2641 * gdb.texinfo: included full Info node and menu crud (as generated
2642 by C-u M-x texinfo-master-menu using the texinfo-2 elisp code).
2644 * Makefile: updated "gdb.dvi" target to use M4 preprocessor;
2645 put in comments-for-future gdb.info target (one day makeinfo will
2648 Tue May 14 13:51:36 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)
2650 * gdb.texinfo: Updated to include new or old undocumented
2651 commands, at least the following (perhaps some others I forgot to
2652 record): info f, info float, info path, info program, info s, info
2653 set, info source, info terminal, info types, info user, set/show
2655 Also covered all recent GDB command renames for v4.
2657 Mon May 13 14:57:46 1991 John Gilmore (gnu at cygint.cygnus.com)
2659 * mipsread.c: Rather than keeping count of how many symtabs
2660 and psymtabs we have, for sorting purposes, count them when
2661 we need to sort. This fixes bug in rereading of symbol tables.
2663 Fri May 10 15:43:33 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)
2665 * infcmd.c: renamed "info path" to "show paths"

2679 * coffread.c, exec.c, infptrace.c, inftarg.c, remote.c, solib.c,
2680 symtab.h, target.c, target.h: Lint.
2681 * core.c: setup and select frame after reading shared libs,
2682 else reading shared libs will clobber them. Lint.
2683 * utils.c (error): Force out any buffered wrap text.
2685 Fri May 3 22:01:56 1991 John Gilmore (gnu at cygint.cygnus.com)
2687 * remote.c: Remove decls of memory_insert_breakpoint
2688 and memory_remove_breakpoint, no longer used. (Suggestion of
2691 * Makefile.dist: use ${subdir} in paths of BFD and LIBIBERTY,
2692 to make it easier to interface to "configure"'d libraries.
2694 Fri May 3 13:10:01 PDT 1991 Roland Pesch (pesch at fowanton.cygnus.com)
2696 * valprint.c: introduce "set p", "set pr", "show p" and "show pr" as
2697 aliases for set/show print.

2753 * coffread.c [TDESC]: Move setting of debug_info from
2754 coff_symfile_read to find_linenos and make it work with BFD.
2756 * cplus-dem.c [__STDC__]: Make x{m,re}alloc return void*.
2758 * signame.c: Cast const char* to char* when assigning to sys_siglist.
2760 * utils.c (strsave): Make arg const char* not char*.
2762 * infrun.c (wait_for_inferior) [SHIFT_INSN_REGS]: Use

2783 Mips bringup and general cleanup
2785 * cplus-dem.c: Move CPLUS_MARKER define to after defs.h.
2786 * infptrace.c (PT_WRITE_D, PT_READ_D): Use correct values.
2787 (This still doesn't seem to make MIPS bkpts work.)

2789 (symbol_file_command, add_file_command): Remove, obsol.
2790 * printcmd.c (ptype_command): Say "an enum" rather than "a enum".
2791 Wrap output appropriately.

2793 selected_frame rather than target_has_stack or coredumping.
2794 * valprint.c (type_print_varspec_suffix): Wrap "ptype" output of
2795 enums appropriately.
2797 Wed May 1 14:10:22 1991 Jim Kingdon (kingdon at cygint.cygnus.com)

2806 can have both ints and enum type_pieces in it.
2807 ({push,pop}_type_int): New functions.
2809 Tue Apr 30 13:18:58 1991 Jim Kingdon (kingdon at cygint.cygnus.com)

2821 symtab.c, cplus-dem.c, value.h, expread.y, valprint.c,
2822 copying.awk, solib.c, inflow.c, symmisc.c
2823 : Lint. Use read_memory not read_memory_integer on CORE_ADDR's.
2824 Use {value_as,unpack}_pointer (added to values.c)
2825 not {value_as,unpack}_long on CORE_ADDR's.
2826 Use longest_to_int (added to defs.h) instead of cast to int.
2827 Remove from_tty arg to mod_path.
2828 Put symfile_bfd in {coff,dbx}read.c not symfile.h.
2829 Use OP_NULL instead of 0 where dummy enum exp_opcode needed.

2872 * param-no-tm.h: Make BITS_BIG_ENDIAN defined to 0/1, not defined
2873 or not defined. Don't define it based on TARGET_BYTE_ORDER if

2876 values.c (modify_field, unpack_field_as_long):

2880 Fri Apr 26 12:02:06 1991 Jim Kingdon (kingdon at cygint.cygnus.com)
2882 * tm-sparc.h: Add comments about gcc version 2 and structure passing.
2884 * xconfig/i386v{,32}{,-g}: Add XM_CFLAGS=-Dgetpagesize()=4096.
2885 gmalloc.c: #if 0 out !HAVE_GETPAGESIZE code.
2887 * expread.y (abs_decl): Accept '&' and '&' abs_decl.

3302 (set_section_command): New command ("section xxx yyy" -- should
3303 be renamed to "set section xxx yyy" FIXME) which sets the

3317 * i386-pinsn.c: Move #includes to top, remove useless ones.
3318 * i386-tdep.c: Don't bother including <.../reg.h> since we

3335 current frame in the core file, if we have one.

3360 * command.c (user_info_1, user_info): New command for listing
3361 the user-defined commands.
3363 Wed Apr 3 15:00:26 1991 John Gilmore (gnu at cygint.cygnus.com)
3365 * dbxread.c (really_free_pendings): Clear file_symbols
3366 and global_symbols after freeing them; otherwise, running
3367 this function twice (if it appears twice on the cleanup
3368 chain), we try to free things twice.
3370 * dbxread.c (read_dbx_symtab): Calculate end_of_text_addr
3371 based on text_addr (the address of text in core), not on addr (the
3372 offset between text in the .o file and in core). This change
3373 is from Peter Schauer.
3375 * main.c: Define ALL_CLEANUPS as a cast of zero.
3376 (return_to_top_level): Use it.
3377 (main): Do all cleanups after each command run as part
3378 of the gdb startup sequence. Also do all cleanups before
3379 entering the command loop, and every time we exit the command
3380 loop and reenter. Before, the cleanups from the startup sequence
3381 were being left undone until the first error!
3382 (command_loop): Rename do_nothing cleanup to command_loop_marker
3383 so we can see it easily when examining the cleanup chain.
3384 (init_signals): Add another do_nothing for signal handling.
3385 (quit_command): Only try to kill target if it has execution.
3386 Problems in the target stack got us into a state where
3387 inferior_pid was nonzero but none of the targets had execution.
3388 In this state you couldn't exit gdb.
3390 * dbxread.c: Two changes from Peter Schauer.
3391 (echo_command): Fflush output after an echo command.
3392 (show_history): Pass all args to cmd_show_list.
3394 * utils.c (init_malloc): Call mtrace to turn on tracing
3395 if the environment variable MALLOC_TRACE is set to a file name.
3396 * mtrace.c: Add source file which provides a log of every malloc,
3397 free, and realloc to a trace file.
3398 * mtrace.awk: Add source file which analyzes the trace file.
3399 * Makefile.dist (GNU_MALLOC, MALLOCSRC): Add mtrace.{c,o,awk}.
3400 (VERSION): Roll to 3.94.3.
3402 * breakpoint.c (breakpoint_1): Add a space to "i watch" output.
3403 (check_duplicates): Don't bother with watchpoints.
3404 (set_raw_breakpoint): Comment about danger of this routine.
3405 (watch_command): Parse and eval all args before calling
3408 * solib.c (find_solib): Avoid error in referencing memory to
3409 see if any more shared libraries have been added. This is
3410 particularly useful if the target has terminated. Bug reported
3413 Changes from Peter Schauer <pesrem@regent.e-technik.tu-muenchen.de>
3414 in bringing up 3.94.2 on the Sun-3.
3416 * Makefile.dist: Include CFLAGS in rule for cplus-dem.o.
3417 * breakpoint.c (enable_breakpoint): Check for valid watchpoint
3418 expression (in scope) before reenabling watchpoint.
3419 * signame.c (init_sigs): Add missing declaration of i, fix
3420 sys_siglist declaration.
3421 * source.c (list_command): Fixed range computation to use
3423 * stack.c (backtrace_command): Do not allow command if target has
3424 no stack, print informative error message.
3425 * target.c (target_command): Do not write into command line
3426 because this fails if the target command is used in a user defined
3427 command. [This change was enhanced by gnu to support any-
3428 unique-prefix matching on target names.]
3429 * valops.c (value_struct_elt): Avoid infinite loop on an
3430 erroneous attempt to print the member of function (try p main.p).
3432 Mon Apr 1 17:05:45 1991 John Gilmore (gnu at cygint.cygnus.com)
3434 * expread.y (name_no_typename): Avoid reduce/reduce errors
3435 caused by ambiguity in handling NAME_OR_INT and NAME_OR_UINT.
3436 Since the GDB parser really doesn't use name_no_typename in a
3437 name-only context, the parser can't tell the diff between
3438 names and numbers here. Avoid allowing a name_no_typename
3439 to be a NAME_OR_*INT to resolve the conflict.
3441 Sun Mar 31 20:12:07 1991 John Gilmore (gnu at cygint.cygnus.com)
3443 Bugfixes from Mark Fox (markf@wrs.com) (test=testField.c):
3445 * valprint.c (val_print_fields): bitfield printing didn't handle
3446 byte order. Indirect through a few more fns to cope.
3448 * values.c (modify_field): also cope with byte order.
3450 Sat Mar 23 10:02:21 1991 John Gilmore (gnu at cygint.cygnus.com)
3452 Cleanup for release 3.94.2:
3454 * Makefile.dist: Pull REMOTE_OBS. Fix saber includes for BFD
3455 include files. Roll version to 3.94.2.
3457 * coffread.c (init_stringtab): Read length into unsigned char
3458 array before swapping; don't assume 32-bit longs.
3460 * target.c (target_info): Don't bother with get_sym_file, just use
3461 the symfile global variable.
3462 * symtab.h, symfile.c (get_sym_file): Delete it.
3464 * dbxread.c (dbx_symfile_init): Don't depend on long == 4 bytes.
3465 (define_symbol): Set symbol line number to 0 if not gcc-compiled.
3466 (read_type): Replace one more error() with complain().
3468 * mipsread.c (parse_partial_symbols): Replace printf with complain.
3470 * i960-tdep.c: Fix copyright attribution.
3472 * config.gdb: Quote all backquotes in doublequotes. You can
3473 quote me on that. BSD 4.4 shell found this one.
3475 * infptrace.c (throughout): The third argument to ptrace is an
3478 * infrun.c (wait_for_inferior): When program has terminated, we
3479 have to call target_terminal_ours before we pop that target off
3480 the stack (e.g. before a call to target_kill or
3481 target_mourn_inferior). This fixes problem where a program
3482 terminates, then GDB stops for (tty output) and you have to type
3483 "fg" to the shell to resume it. FIXME: This code for what to
3484 do after termination really should be in normal_stop instead.
3486 * gdbcore.h (read_memory_check): Change declaration; it changed
3489 * terminal.h: Include <sgtty.h> before <sys/ioctl.h>, since in BSD
3490 4.4 prereleases, this avoids a bug in their sgtty compatability
3492 * remote.c: Use terminal.h rather than hand-rolling the same.
3494 * signame.c, signame.h (psignal): Arg is unsigned, not int.
3495 * utils.c (strsave, strstr): Fix arg types.
3496 * valprint.c (val_print): lint
3498 MIPS symbol table support from Per Bothner:
3500 * symfile.c (symtab_fns): Remove initializer table that needs to
3501 be hacked for each new symbol file format supported.
3502 (add_symtab_fns): New function, chains symbol table
3503 handlers into the global list.
3504 (symfile_init): Search this list.
3505 * symfile.h: Add next pointer, declare add_symtab_fns.
3506 * coffread.c (_initialize_coffread): Call add_symtab_fns.
3507 * dbxread.c (_initialize_dbxread): Call add_symtab_fns.
3509 * mipsread.c (psymtab_to_symtab_1): return void instead of (struct
3510 symbol *). Thus, we no longer need the hack to trash
3511 pst->filename. Good, since that hack confused code in symfile.c!
3513 (reorder_symtabs, destroy_all_symtabs): Removed static
3514 all_symtabs, which was used to qsort symtabs in reorder_symtabs.
3515 Instead, the latter now uses a temporary array (stack-allocated
3516 from an obstack, and then freed).
3518 (parse_symbol): Added a hack to fix up BLOCK_{START,END} if they
3519 haven't been set in the outermost stBlock of a procedure. This was
3520 a problem with f77 binaries on Ultrix 4.?.
3522 (new_symtab, new_symbol, new_type): Continue changing code to use
3523 obstacks more and otherwise conform to dbxread internal style.
3524 Made the free_code of symtabs be free_linetable (as in dbxread)
3525 instead of free_contents. This implies memory leaks when reading
3526 a new symbol table, until the conversion is finished. Did change
3527 (struct symbol) and (struct type) to be allocated on the
3528 symbol_obstack. Blocks and blockvectors are among the things
3531 * mipsread.c (parse_partial_symbols, parse_fdr): It hasn't been
3532 tested much, but it solved one problem (reported by Meissner), and
3533 cleans up some other things. The problem happened when an
3534 included file contains actual code (functions) and not just
3535 definitions. The mips coff is a little inconvenient there, since
3536 it may cause a procedure to be mapped to the wrong psymtab.
3538 * mips-tdep.c (heuristic_proc_desc): Minor cleanup.
3539 * mips-xdep.c (fetch_core_registers): Minor cleanup. FIXME,
3540 this will need work for the new core paradigm.
3542 Opcode patches from the net:
3544 * mips-opcode.h: fix incorrect disassembly of the mfc1, cfc1, and
3545 ctc1 instructions. Also, the cvt.d.w and cvt.s.w instructions were
3546 missing altogether - they are added here. From Bruce Bauman.
3547 * mips-opcode.h: The low mask for C0 instructions was too small.
3548 From Garrett Lau. I modified the fix to check the entire 32-bit
3551 * ns32k-opcode.h: Fix opcodes for deiw and deid. From Bruce
3554 Thu Mar 21 12:56:46 1991 John Gilmore (gnu at cygint.cygnus.com)
3556 Roll in changes from Per Bothner (Tue, 25 Sep 90 11:11:04):
3558 * dbxread.c (read_type): Pointer subtraction (value_sub in
3559 valarith.c) sometimes failed because the types of the
3560 pointers being subtracted were not identical.
3561 These differed because dbxread.c was allocating pointer types
3562 using dbx_alloc_type+smash_to_pointer_type instead of
3563 lookup_pointer_type. I failed to find a justification for the
3564 former, so I changed it to use the latter. Similarly, I
3565 replaced smash_to_function_type by lookup_function_type,
3566 and smash_to_reference_type by lookup_reference_type.
3568 * mipsread.c (parse_symbol, upgrade_type, parse_procedure,
3569 _initialize_mipsread): corresponding changes.
3571 * symtab.c (smash_to_{pointer,reference,function}_type): eliminate.
3573 * source.c (mod_path): Do tilde_expand on each component of the path,
3574 rather than on the (list of) paths as a whole.
3575 (print_source_lines): Set first_line_listed in addition to
3576 current_source_symtab and current_source_line. If the source was
3577 not findable, after a "dir" command to fix the problem,
3578 a "list" would get the wrong lines.
3580 While I was there... (gnu):
3582 * dbxread.c (read_type): Change error to complaint.
3584 Thu Mar 21 12:56:46 1991 John Gilmore (gnu at cygint.cygnus.com)
3586 First attempt at detailed understanding of symbol table memory alloc.
3588 * dbxread.c (dbx_symfile_read): Free our string table if we
3589 aren't the mainline. Free the "info" struct since we're done with
3591 (init_psymbol_list): Free any previously allocated psymbol lists.
3592 (): FIXME: Should realloc-down the psymbol lists when done reading
3593 the main symbol file?
3595 * symmisc.c (free_symtab): Free fullname field too.
3597 * xm-hp300hpux.h (USG): #undef then #define so Makefile can -D.
3598 (REGISTER_ADDR): Make result type unsigned int.
3600 * xconfig/{i386*,hp300hpux,altosgas,altos}: All config files that
3601 define REGEX must also define REGEX1 (its dependency).
3603 Tue Mar 19 21:28:57 1991 John Gilmore (gnu at cygint.cygnus.com)
3605 * tconfig/i960: No longer works, points you at vxworks960 or
3608 * xgdb.c, XGDB-README: Remove file. Users can get the much
3610 * Makefile.dist: Remove all trace of xgdb.
3612 * breakpoint.c (breakpoint_1): Pass demangle arg to
3613 print_address_symbolic.
3614 (clear_breakpoints): Remove unused function.
3615 (breakpoint_re_set_one): Guts of breakpoint_re_set.
3616 (breakpoint_re_set): Use catch_errors to do them all anyway.
3618 * gdb-int.texinfo (Host versus Target): Add section on what is
3619 a "host" feature versus what is a "target" feature.
3621 * infcmd.c (path_command, path_info): Handle the PATH variable
3622 (object search path) as conveniently as the source search path.
3623 * environ.c (set_in_environ): Set some vars in GDB's environment,
3624 in addition to the child's. PATH, G960BASE, G960BIN for starters.
3625 * source.c (mod_path): New function, from guts of
3626 directory_command, modifies a path. Used by path_command.
3627 (directory_command): Call it.
3628 * defs.h (strsave): Declare.
3630 * utils.c (sevenbit_strings): Add new printing option.
3631 (printchar): Use it.
3632 (strsave): Provide this handy helper routine.
3633 (set_width_command): Rename set_screen_width_command.
3634 (_initialize_utils): "set screen-width" => "set width";
3635 "set screen-height" => "set height"; add sevenbit-strings.
3637 * infcmd.c (do_registers_info): Print floating point registers
3638 in raw hex as well as float format, regardless of whether it is
3639 a "virtual" convertible register.
3640 * tm-sparc.h (PRINT_REGISTER_HOOK): Print every pair of float
3641 regs as a double, just in case it's being used that way.
3642 * values.c (unpack_long): Comment on array/function coercion.
3643 (unpack_double): Argument is in target byte order now. For
3644 integer arguments, just call unpack_long and float the result.
3645 * m68k-tdep.c: include defs.h for "const" handling.
3646 * remote-nindy.c: Use ieee-float stuff.
3647 (nindy_fetch_registers): Unpack double regs to host double, then
3649 (nindy_store_registers): Pack extendeds to host double, flip
3650 around by misusing unpack_double, send as target double.
3652 * tm-vxworks68.h (FRAME_CHAIN): Handle current frame pointer of
3653 zero, as when stopped at the first instruction of a process.
3655 * blockframe.c: Fix filename in comment (param.h => tm.h).
3656 * sparc-tdep.c (skip_prologue): More explicit nudging comments.
3657 * tm-68k.h: Fix typos.
3659 Fri Mar 15 01:09:34 1991 John Gilmore (gnu at cygint.cygnus.com)
3661 Changes from a bringup on the DEC Vax under Ultrix 4.0.
3663 * coredep.c (fetch_core_registers): Pass end-address of register
3664 section to register_addr as expected. Don't call supply_register
3665 if we'd just pass it garbage.
3667 * dbxread.c (read_dbx_symtab): Skip N_NSYMS on Ultrix.
3669 * exec.c (xfer_memory): Use boolean xfer_fn result, not int.
3671 * target.c (push_target, target_info): Cast enums to int for < or
3674 * stack.c (print_frame_info): Identify source file & line
3675 even if we can't print it.
3677 * xm-vax.h (MISSING_VPRINTF): No longer missing in Ultrix V4.0.
3679 Sat Mar 9 10:08:20 1991 John Gilmore (gnu at cygint.cygnus.com)
3681 Clean up IEEE floating point support.
3683 * ieee-float.h: New file.
3684 * ieee-float.c: Write real routines to convert between host
3685 doubles and various target IEEE extendeds.
3686 * m68k-xdep.c: Eliminate assembler code for extended floats.
3687 * xconfig/{3b1,altos,altosgas,hp300bsd,isi,news,news1000,sun2os3,
3688 sun2os4,sun3,sun3os3,sun3os4}: Eliminate use of m68k-xdep.o.
3689 * tm-i960.h, tm-68k.h (REGISTER_CONVERT_TO_VIRTUAL,
3690 REGISTER_CONVERT_TO_RAW): Use ieee_extended_to_double and
3691 double_to_ieee_extended.
3692 * i960-tdep.c: Define ext_format_i960.
3693 * m68k-tdep.c: Define ext_format_68881.
3694 * sparc-tdep.c: Define ext_format_sparc, though unused.
3695 * Makefile.dist (HFILES): Add ieee-float.h.
3696 * inftarg.c: #include "ieee-float.h" for the REGISTER_CONVERT
3699 Obsolete the "coffstrip" program in favor of using BFD's strip.
3701 * nindy-share/coffstrip.c: Remove file.
3702 * nindy-share/nindy.c (coffstrip): Routine to run bfd_strip.
3703 * Makefile.dist: Remove references to nindy-share/coffstrip.c.
3704 * tconfig/nindy960: Remove reference to coffstrip.o.
3706 * Makefile.dist: Roll version number to 3.94.1 (not yet final).
3708 Wed Mar 6 09:56:45 1991 John Gilmore (gnu at cygint.cygnus.com)
3710 * symfile.h: Add symfile_bfd, common between dbxread and coffread.
3711 * dbxread.c: Remove static symfile_bfd.
3712 * infcmd.c (do_registers_info): Add PRINT_REGISTER_HOOK, though
3714 * inftarg.c (child_detach): Pop the child_ops vector if the
3715 detach is successful.
3716 * remote-nindy.c (nindy_create_inferior): Don't push a new
3717 nindy_ops since nindy uses the same one for execution and memory
3719 * core.c (core_ops): Use child_attach and child_create_inferior
3720 rather than default attach and create_inferior functions.
3722 Handle floating point registers in core files.
3724 * sparc-xdep.c (fetch_core_registers): Rewrite for float support.
3725 * sun3-xdep.c (fetch_core_registers): Rewrite for float support.
3726 This version untested since BFD doesn't yet support sun3 core
3728 * hp300hpux-xdep.c: Rewrite fetch_core_registers to new calling
3729 conventions. Fix comments and style. This version has not
3730 been compiled yet, since we have no HP inhouse.
3731 * core.c (get_core_registers): Look for two sections, ".reg"
3732 and ".reg2", and pass both to fetch_core_registers sequentially.
3734 Revise directory path yet again.
3736 * source.c (forget_cached_source_info): Not static any more.
3737 (init_source_path): New default source path is "$cdir:$cwd".
3738 (dir_command): Handle variable arguments ($cdir, $cwd).
3739 (source_info): Print "Compilation directory" rather than
3740 "Originally compiled in" to remind people of $cdir.
3741 (openp): If the path contains $cwd, use current directory.
3742 (open_source_file): If compilation directory is known, replace
3743 first $cdir in path with the compilation directory.
3744 (print_source_lines): Even if we can't print the lines, set the
3745 current symtab and line for future commands like "info source" or
3746 "breakpoint". Also, error message now contains the file name,
3747 line number, and file access error message.
3748 (_initialize_source): Fix help text to describe changes.
3749 * main.c (cd_command): Forget cached source info when we chdir.
3750 * utils.c (strstr): Add simple implementation.
3752 Tue Mar 5 01:41:40 1991 John Gilmore (gnu at fowanton.cygnus.com)
3754 * coffread.c (read_one_sym, init_linetable, init_stringtab):
3755 Byte-swap COFF symbol tables if necessary when reading them in.
3756 Use complain() to replace error message in one spot. Needs
3757 corresponding change in bfd/coff-code.h to make some symbol
3758 swapping routines non-static.
3760 Mon Mar 4 00:53:40 1991 John Gilmore (gnu at cygint.cygnus.com)
3762 Merge changes from Eirik Fuller, for UTek.
3764 * defs.h (errno): Add declaration.
3765 * altos-xdep.c, arm-xdep.c, convex-xdep.c, gould-xdep.c,
3766 hp300hpux-xdep.c, infrun.c, inflow.c, infptrace.c, i386-tdep.c,
3767 i386-xdep.c, pyr-xdep.c, mips-xdep.c, remote-eb.c, remote-nindy.c,
3768 remote-vx.c, source.c, standalone.c, stuff.c, sun386-xdep.c,
3769 symmetry-tdep.c, symmetry-xdep.c, umax-xdep.c, utils.c: Eliminate
3770 declarations of errno.
3772 * remote-eb.c: Define B19200 and B38400 as EXTA and EXTB.
3774 * remote-vx.c: Include <sys/time.h> for UTek; Sun gets it via
3775 <rpc/rpc.h> and <rpc/types.h>.
3777 Sat Mar 2 15:47:55 1991 John Gilmore (gnu at cygint.cygnus.com)
3779 * i960-tdep.c (examine_prologue): Add new argument limit,
3780 which stops the scan at the end of the prologue, or at the PC.
3781 This fixes a problem where it walks down into the code for the
3782 user's statements if that code looks like function prologues.
3783 Mark Fox and I have been bouncing this code back and forth, making
3784 small changes to it. Callers changed to match.
3786 Tue Feb 26 01:47:07 1991 Cygnus John Gilmore (cygnus at yuba)
3788 Cleanup for gdb-3.94 release final:
3790 * Makefile.dist: Remove remote-vx.c, remote-nindy.c, and all
3791 the .c files from vx-share and nindy-share, from the various
3792 macros, since they are not found via ALLDEPFILES.
3793 (SFILES): Add tm-i960.h.
3794 (alldeps.mak rule): Break out ALLDEPFILES_MAINDIR and
3795 ALLDEPFILES_SUBDIR. List all the nindy and vxworks subdir files
3797 (TAGFILES_MAINDIR): Change ALLDEPFILES to ALLDEPFILES_MAINDIR.
3798 (gdb.tar.Z): Use ALLDEPFILES_SUBDIR as well as SFILES_SUBDIR.
3800 Mon Feb 25 16:02:35 1991 Cygnus John Gilmore (cygnus at oldman)
3802 * am29k-tdep.c: Add contribution line.
3803 (examine_prologue): Cache information about function prologues in
3804 the misc-function-vector to avoid lots of references over the
3805 serial line while examining instructions.
3807 * core.c (core_close): New function made from cleanup_core.
3809 * core.c, exec.c, inftarg.c, remote-eb.c, remote-nindy.c,
3810 remote-vx.c, remote.c, target.c, target.h,
3811 Update target_ops vector to add attach, close, and load entries.
3812 Use add_syms_addr_command, not add_file_addr_command, for
3813 add_file. Break out close routine from existing code.
3815 * dbxread.c (really_free_pendings): Don't free pending_blocks;
3816 they are in an obstack.
3817 (read_dbx_symtab): Relocate end_of_text_addr in the psymtab.
3819 (define_symbol): Add symbol type parameter; change callers;
3820 pass type parameter to DBX_PARM_SYMBOL_CLASS macro to allow
3821 it to influence the symbol class on the i960.
3822 (define_symbol): Swap LOC_CONST's into target byte order.
3824 * exec.c (exec_close): New function.
3825 (exec_file_command): Call it.
3827 * findvar.c (read_relative_register_raw_bytes): Doc byte order,
3828 Fix byte order of frame pointer.
3829 (read_var_value): Result of 0 if var's value can't be found,
3830 e.g. missing FRAME_ARGS_ADDRESS. Byte-swap LOC_CONST and
3831 LOC_LABEL values to target order. Add LOC_LOCAL_ARG.
3832 (locate_var_value): Use read_var_value and use its lazy address
3833 as the location of the var's value. Lint.
3835 * i960-pinsn.c (next_insn): Add routine from vxgdb for scanning
3838 * i960-tdep.c (arg_address, i960_frame_find_saved_regs): Remove
3839 obsolete Intel versions in favor of vxgdb versions.
3840 (check_host, byteswap, byteswap_val, reorder_val): Eliminate
3841 code dealing with byte order of values, which Intel did in host byte
3842 order rather than gdb-4's target byte order.
3843 (i960_frame_chain_valid): Move to nindy-tdep.c.
3844 (examine_prologue, skip_prologue, frame_find_saved_regs,
3845 frame_args_address, leafproc_return, saved_pc_after_call,
3846 pop_frame): Add vxgdb versions from Mark Fox.
3847 (examine_prologue, frame_struct_result_address): Add code
3848 to deal with the saved value of G13 (struct return address
3850 (frame_args_address): Modify Mark's version to prefer the
3851 saved value over the current value in the topmost frame.
3852 Cache result in the frame info to avoid performance hair in
3854 (print_fault): Add gdb960 code for printing faults.
3855 (_initialize_i960): Actually call check_host.
3857 * ieee-float.c (ieee_extended_to_double, ieee_double_to_extended):
3858 add stub routines. FIXME, these currently just return zero!
3860 * infcmd.c (program_info): Use PRINT_RANDOM_SIGNAL.
3861 (attach_command): Call target_attach, not target_open, now.
3863 * infrun.c (normal_stop): Make global, not static, for vx_attach.
3864 (child_attach): Rename from child_open.
3865 (wait_for_inferior): Use PRINT_RANDOM_SIGNAL. If stop_pc is zero,
3866 don't confuse it with a zero step_resume_break_address.
3868 * inftarg.c (child_detach): Eliminate inferior_pid test.
3869 (child_files_info): Clean up message a bit.
3870 (child_ops): Use child_attach, not child_open, to attach.
3872 * mem-break.c: #ifdef out the whole file if BREAKPOINT is not
3873 set (e.g. on VxWorks or NINDY). Move read_memory_nobpt from
3874 findvar.c to here, since it depends on the contents of the
3875 shadow_contents of breakpoints, but keep if #if 0 since it is
3878 * nindy-tdep.c: New file, contains nindy_frame_chain_valid, moved
3881 * printcmd.c (address_info): Handle LOC_LOCAL_ARG. Lint.
3882 (ptype_command, display_command): Eliminate have_inferior_p and
3883 have_core_file_p in favor of target_has_stack or
3884 target_has_execution.
3885 (print_frame_args): Handle LOC_LOCAL_ARG. Eliminate duplicate
3886 code for actually finding the values of arguments, though we still
3887 keep track of the maximum stack offset for use in printing unnamed
3888 arguments. Handle missing FRAME_ARGS_ADDRESS.
3890 * remote-nindy.c (i960_print_fault): Move to i960-tdep.c.
3891 (struct nindy_regs): Define registers passed to/from nindy.
3892 (nindy_fetch_registers, nindy_store-registers): Translate between
3893 nindy and GDB formats for the registers.
3894 (dcache_init): Statically allocate the cache, since it was being
3895 allocated by a malloc that was never freed anyway.
3896 (nindy_create_inferior): Error, not core dump, if no exec file.
3897 (nindy_before_main_loop): Use target_load, not target_add_file.
3899 * remote-vx.c (net_load): Specify large timeout for load
3900 requests. Allow user to break out with INTERRUPT.
3901 (net_break): Remove useless code, clean up. Change callers.
3902 (parse-args, skip_white_space, find_white_space): Clean up arg
3903 parsing to cope with quoted strings.
3904 (net_wait, net_quit): Never call error, just return status.
3905 (vx_read_register, vx_write_register): Cleanup status checking.
3906 #ifdef the code based on which CPU we are using (960 or 68k),
3907 FIXME, this should be completely general but it isn't yet.
3908 (vx_xfer_memory, vx_resume): Cleanup status checking.
3909 (vx_run_files_info): Improve message.
3910 (vx_load_command): Renamed from vx_add_file_command. Allow load
3912 (net_ptrace): Remove unused routine.
3913 (vx_wait): Adopt code from vxgdb960 to cope with broken
3914 connections to target machine and prompt to disconnect. Remove
3915 debug printouts. Map some EVENT_'s to SIGnals.
3916 (add_symbol_stub, vx_open): Print names of object files we found,
3917 and "ok" if we read their symbols OK. Clarify output in general.
3918 (vx_attach, vx_detach, vx_kill): Add these commands.
3919 (vx_convert_from_virtual, vx_convert_to_virtual): Simplify.
3920 (vx_run_ops): Turn off all_mem, to avoid spurious msg in the
3921 "info files" output, and create_inferior, since we already have
3924 * stack.c (frame_info): Replace Frame_unknown with 0.
3925 (print_frame_arg_vars): Handle LOC_LOCAL_ARG.
3926 (return_command): Pop until the PC matches as well as the FP,
3927 so it works even if the FP is shared with another function,
3928 as in "frameless" or "leaf" procedures.
3930 * symfile.c (load_command): renamed from add_file_target_command.
3931 (add_syms_addr_command): renamed from add_file_addr_command.
3932 (add_syms_command): Stub to call target_add_syms.
3933 (_initialize_symfile): Change command names and descriptions,
3934 add-file => add-syms, and load from alias to its own command.
3936 * target.c (kill_or_be_killed, maybe_kill_then_attach,
3937 maybe_kill_then_create_inferior): Default for attempts to start
3938 a process, if one is already running, is to ask about killing
3939 it and retry if yes.
3940 (upstack_create_inferior): #if-0 it, strata obsolete it.
3941 (push_target, unpush_target, pop_target): to_close() a target
3942 before unstacking it.
3943 (target_info): Renamed from target_files_info.
3944 (_initialize_targets): Rename "i files" as "i target", accessible
3947 * target.h: Improve comments about the target_ vectored routines.
3949 * tm-i960.h: Remove NINDY-specific stuff to tm-nindy960.h.
3950 Convert commenting style to standard GNU style.
3951 (DBX_PARM_SYMBOL_CLASS): allow LOC_LOCAL_ARG's to be recognized.
3952 (SKIP_PROLOGUE): No longer a no-op.
3953 (SAVED_PC_AFTER_CALL): Now handles leaf procedures.
3954 (*_REGNUM): Sort register numbers.
3955 (REGISTER_BYTES, REGISTER_BYTE, REGISTER_RAW_SIZE,
3956 MAX_REGISTER_RAW_SIZE, REGISTER_CONVERTIBLE,
3957 REGISTER_CONVERT_TO_VIRTUAL, REGISTER_CONVERT_TO_RAW): Float regs
3958 are now 10 byte extendeds, not 8 byte doubles.
3959 (FRAME_CHAIN_VALID): Make this config-dependent, since it differs
3960 for nindy versus vxworks targets. FIXME, this should possibly go
3961 in the target vector.
3962 (EXTRA_FRAME_INFO, INIT_EXTRA_FRAME_INFO): Cache both
3963 frame_saved_regs and arg pointer with each frame.
3964 (FRAMELESS_FUNCTION_INVOCATION): New leafproc support.
3965 (FRAME_ARGS_ADDRESS): Use cached result.
3966 (FRAME_ARGS_ADDRESS_CORRECT): New, avoids g14 guessing.
3967 (FRAME_FIND_SAVED_REGS): Change arg to subsidiary fn.
3968 (PRINT_RAMDON_SIGNAL): Call print_fault.
3969 (POP_FRAME): Now works.
3971 * tm-nindy960.h: Break this off tm-i960.h. NINDY-specific
3972 option parsing and startup; STACK_END_ADDR, FRAME_CHAIN_VALID,
3973 BREAKPOINT, and DECR_PC_AFTER_BREAK are here.
3974 (ADDITIONAL_OPTION_HANDLER): use target_load, not
3977 * tm-vxworks960.h: Break this off tm-i960.h. VxGDB specific
3978 startup; DECR_PC_AFTER_BREAK, and FRAME_CHAIN_VALID are here.
3980 * valarith.c (value_subscripted_rvalue): Avoid handling
3981 floats and doubles specially; it gave alignment errors. Lint.
3983 * valops.c (value_of_variable, value_of_this): Error if unknown
3986 * valprint.c (print_floating): Bcopy rather than pointer-deref,
3987 to avoid alignment problems.
3988 (value_print): Handle unknown value address.
3989 (cplus_val_print): Two args are ignored; remove them. Change caller.
3990 (val_print): Use unpack_long rather than pointer-deref.
3993 (unpack_long, unpack_double): Use bcopy rather than pointer-deref
3994 to avoid alignment problems.
3995 (value_being_returned): Error if return value unknown.
3996 (set_return_value): Add bogosity warning, FIXME. *
3998 * TODO: A woman's work is never done.
4000 * Makefile.dist: Distribute REMOTE_OBS into tconfig files.
4001 Separate INCLUDE_CFLAGS for use with lint. Add LINTFILES.
4002 Add ieee-float.o to OBS.
4003 * tconfig/{nindy960,vxworks68,vxworks960}: Include the desired
4004 REMOTE_OBS remote-interface files in the TDEPFILES and TM_FILE.
4005 * tconfig/i960: FIXME. Half-merge, produce warning if config'd.
4007 Changes to generalize the VxWorks RPC protocol slightly, to handle
4008 i960 as well as 68000.
4010 * vx-share/dbgRpcLib.h (VX_SOURCE_STEP): Add.
4011 * vx-share/reg.h: Produce i960 regs #ifdef I80960
4012 * vx-share/xdr_ptrace.c: Skip FPA registers if 960.
4013 * vx-share/xdr_rdb.h: Add SOURCE_STEP struct and xdr decl.
4014 * vx-share/xdr_rdb.c: Add xdr_SOURCE_STEP routine.
4015 * vx-share/xdr_regs.c: Add xdr_regs, xdr_fp_status, xdr_ext_fp
4016 for i960. Change xdr_vectors to xdr_opaques for 68k registers,
4017 so they will move in target byte order rather than network
4018 byte order (happens to be the same).
4020 Mon Feb 25 03:41:44 1991 John Gilmore (gnu at cygint.cygnus.com)
4022 * tm-convex.h (END_OF_TEXT_DEFAULT): Remove #if 0'd block.
4024 Sun Feb 24 00:55:53 1991 John Gilmore (gnu at cygint.cygnus.com)
4027 Add contribution lines to various files, showing where they
4030 * breakpoint.c (break_insn, check_break_insn_size,
4031 read_memory_nobpt): Remove to mem-break.c.
4033 * xm-*.h, param-no-tm.h, tm-29k.h, valprint.c: Change BYTE_ORDER to
4036 * tm-29k.h (STAB_REG_TO_REGNUM): Warn user if symbol table
4037 entry has bad register number. This change is not
4038 tested in this release, FIXME.
4040 * frame.h: Eliminate Frame_unknown in favor of a simple zero.
4043 * value.h: Force value's contents field to be aligned to hold
4044 at least a double or a long long (if supported). This avoids
4045 doing bcopy's in and out of the contents field.
4047 (step_1): Avoid coredump under obscure circumstances when we
4050 * symtab.h (misc_info): Add field to misc function vector for
4051 any kind of cached information the target code desires. AMD
4052 29000 uses this to avoid repeating examine_function_prologue's.
4054 * coffread.c: Lint. Remove static symfile, read_section_header.
4055 core.c (have_core_file_p): Lint: remove.
4056 expprint.c (print_subexp): Lint.
4057 infptrace.c, valops.c, valprint.c: lint.
4059 Roll in changes from vxgdb-5.0.1:
4061 * symtab.h: Comment byte order of each address class. Add
4062 LOC_LOCAL_ARG for frame-relative args (960).
4063 expread.y: Use LOC_LOCAL_ARG where LOC_ARG is used.
4064 symtab.c, symmisc.c: ditto.
4066 * infrun.c (init_wait_for_inferior): Clear stop_signal.
4068 * remote.c (remote_resume): Error if resume with a signal.
4070 * symfile.c (prim_record_misc_function): Clear misc_info.
4071 (fill_in_vptr_fieldno): Check stub type of arg.
4073 * valops.c (value_cast): Avoid looking up names of types whose
4074 name we don't know, to prevent coredump. Sun CC produces typedef
4075 rtx and the name of *rtx is zero...
4077 Mon Feb 18 21:16:25 1991 John Gilmore (gnu at cygint.cygnus.com)
4079 Roll in changes from final AMD 29000 port (Tiemann).
4081 tconfig/am29k: Add COFF_ENCAPSULATE and TARGET=TARGET_AM29K
4082 for ../include/a.out.encap.h. This might not work now that BFD
4083 is separately compiled. Instead, BFD support for encap will have
4084 to translate machine type 29k into the right COFF_MAGIC.
4086 * infcmd.c: Remove references to inferior_pid that aren't used
4087 in actual ptrace calls; use target_has_execution, etc.
4088 (have_inferior_p): Remove function.
4089 (program_info): Print target info rather than "process number";
4090 avoid gratuitous messages unless from_tty.
4091 (run_stack_dummy, finish_command): Set proceed_to_finish.
4092 infrun.c: Remove inferior_pid refs. Decl & init proceed_to_finish.
4093 main.c: Lint. Lose have_inferior_p().
4094 inferior.h (have_inferior_p): Remove, lint.
4095 (proceed_to_finish): Add flag to ask that all regs be saved
4096 by normal_stop, for the few commands that need it, speeding up
4097 serial I/O. Add comments to stop_registers.
4099 * remote-eb.c: Remove newline from breakpoint message we grep
4100 for. Never time out when running the user program.
4104 Wed Feb 13 15:34:40 1991 John Gilmore (gnu at cygint.cygnus.com)
4106 Roll in changes from vxgdb-5.0.1:
4108 * dbxread.c (read_dbx_symtab): If we encounter a "FORTRAN COMMON"
4109 symbol in its raw form, we are processing an unlinked ".o" file.
4110 See if the target environment has assigned it an address, using
4111 target_lookup_symbol (VxWorks does), and enter it into the symtab
4114 * tm-vxworks.h (FRAME_CHAIN, FRAME_CHAIN_VALID): Override usual
4115 68k versions for a simpler version that assumes zero FP at bottom.
4116 Fixes bug of truncated stack reports.
4118 * target.h (target_lookup_symbol): Define this routine's args
4119 and result, finally.
4121 * target.c (nosymbol): Default routine for target_lookup_symbol.
4122 (target_default): Default lookup_symbol and call_function too.
4123 (files_info): Only print has_all_memory warning if a non-dummy
4126 * remote-vx.c (vx_read_register, vx_convert_to_virtual,
4127 vx_convert_from_virtual): If target does not have floating point,
4128 zero register "values", and avoid doing cross-net conversions.
4129 (vx_lookup_symbol): Rename net_lookup_symbol, add to vectors.
4130 (vx_open): Rearrange code that attaches to target and reads
4131 symbols for all loaded modules, to work if some of the modules
4132 are not accessible. Add symbol_stub() and add_symbol_stub()
4133 as callbacks from catch_errors(). Allow connect attempt to be
4134 interrupted painlessly with ^C (FIXME, there are still some bugs
4135 if the interrupt happens during symbol reading.). Print
4136 final message with puts_filtered, since symbol messages are
4141 * main.c (catch_errors): Only print errstring if non-null.
4142 (command_loop): Avoid an ioctl per command to test ISATTY.
4144 * remote-vx.c (net_load): make static; avoid sophomoric msg.
4145 (vx_xfer_memory): Return correct result!
4146 (vx_files_info): Indicate whether target has float or not.
4147 (vx_lookup_symbol): Complain, not error, if target gone.
4148 (vx_open): Print "Connected" msg before disabling immediate-quit.
4149 [FIXME: lookup_symbol and vx_open changes need testing.]
4151 target.c, remote-eb.c, inftarg.c, am29k-opcode.h, target.h,
4152 tm-29k.h, tmm-vxworks68.h, symfile.c, gdb-int.texinfo: Add
4153 contributor lines and update copyrights to 1991.
4155 Changes from an attempted H-PUX host port:
4157 * infptrace.c (PT_ATTACH, PT_DETACH): Handle HP/UX, which
4158 defines PT_ATTACH and PT_DETACH but not PT_KILL.
4159 * remote-eb.c (eb_open): Misplaced endif kills sysv H/PUX.
4160 * remote-vx.c: include <sys/time.h> for HPUX.
4161 * hp300hpux-xdep.c (fetch_core_registers): Rewrite old
4162 "core_file_command" routine to BFD regime. May not work yet.
4164 Attempted port of "gdb-3.4 Van Jacobson xgdb" to modern gdb.
4166 * xgdb.c: Replace X10 version with some VJ version.
4167 (FIXME: Its copyright assignment is not on record.)
4168 * xgdb.c: Update include files to X11R4 (Xaw crud).
4169 (xgdb_display_source, create_text_widget): fix call to
4170 get_filename_and_charpos. Rewack source window stuff for X11R4
4171 (gleaned from include files, and "nm's" of binary libraries, since
4172 I had no doc available).
4173 (append_selection, append_selection_word): Disable with FIXME
4174 since R4 changed interface here.
4175 (create_buttons): Add back the old set of buttons.
4176 (xgdb_create_window): Fix call to XtInitialize (&argc not argc).
4178 * Makefile.dist (xgdb, xgdb-init.c): Update for X11R4 on Suns.
4179 Roll VERSION to 3.94 (not yet final though).
4181 Sat Feb 9 09:46:25 1991 John Gilmore (gnu at cygint.cygnus.com)
4183 * obstack.h (obstack_ptr_grow, obstack_ptr_grow_fast,
4184 obstack_int_grow, obstack_int_grow_fast): Eliminate
4185 cast on left of assignment, which gives MIPS cc fits and is
4188 * sparc-pinsn.c (print_insn): Eliminate 'set' test, subsumed by
4189 F_ALIAS. Use printf, not fprintf, when not passing a file
4191 (compare_opcodes): Check that identical instructions have
4192 identical opcodes, complain otherwise.
4194 * sparc-opcode.h (st %fsr): Fix opcode "lose" mask. This
4195 was reported by Roland McGrath.
4196 (unimp): Only match if exactly zero instruction. (Roland)
4197 (branches and traps): Generate all variations of these
4198 instructions with macros, based on a single call that defines
4199 each condition name and its binary representation.
4200 (set): Turn on alias bit, to avoid test in sparc-pinsn.c.
4202 * valprint.c (val_print_fields): Take, and use, format parameter.
4203 This means that "p/x struct" again prints the elements in the
4204 desired format. Changed callers.
4206 * stack.c (frame_info): Use filtered output, and indicate wrap
4207 points. Remove kludgy formatting designed to avoid line wrap.
4209 * utils.c (wrap_here): If the line is already full (because
4210 we had printed a long indent or long wrapped string), do an
4211 immediate newline-and-indent.
4213 * m68k-pinsn.c (print_insn_arg): Bugfix from
4214 ntmtv!thompson@ames.arc.nasa.gov (Mike Thompson): 'bkpt #0'
4215 instruction is incorrectly disassembled as bkpt #8.
4217 * dbxread.c (end_psymtab): Bugfix from Peter Schauer
4218 <pesrem@regent.e-technik.tu-muenchen.de>: If you want to set a
4219 breakpoint in a *.y file gdb will say Reading in symbols for *.y...
4220 and then will dump core (sometimes). I traced it back to an
4221 uninitialized symfile_name in psymtab_to_symtab.
4222 (const_vol_complaint): Add quotes to message.
4223 (define_symbol): Only believe line number if gcc_compiled.
4224 Avoid allocating symbol if we will not return it.
4226 Add target strata support so that newly established targets go
4227 into their right place in the target stack (e.g. a new exec file
4228 doesn't wipe out the ability to access the running process).
4230 * target.h, core.c, exec.c, inftarg.c, remote-eb.c,
4231 remote-nindy.c, remote-vx.c, remote.c, target.c: Add to_stratum
4232 and initialize it properly in all the targets.
4234 * target.h: Document strata. Change return type of push_target.
4236 * target.c (nomemory): new function for dummy memory access.
4237 (tcomplain): Rename complain, now also used in symfile.c.
4238 (push_target): Push targets within strata. New return value shows
4239 whether new target is on top of stack or not. Always keep dummy
4241 (target_files_info): Ignore dummy target.
4243 * core.c (core_open): Warn user, and skip accessing file, if the
4244 core target is not the topmost target in the stack.
4245 * remote-nindy.c (nindy_create_inferior): Avoid unpush_target, now
4248 * remote-vx.c: Remove vx_prepare_to_store from vxworks memory
4249 target_ops, it doesn't belong there since we have no regs there.
4250 Change name of target from machine => memory to clarify.
4252 Thu Feb 7 16:32:09 1991 John Gilmore (gnu at spiff.cygnus.com)
4254 * Freeze version 3.93 for release.
4256 * Makefile.dist: Handle vx-share and nindy-share subdirs
4257 properly when building gdb.tar.Z.
4259 * symtab.c: lint; add no_symtab_msg to consolidate the messages
4260 printed in various places, so I could change just one copy.
4262 * dbxread.c, coffread.c: Change references to bfd->iostream
4263 to cast to FILE *, now that BFD avoids needing types defined
4264 in other header files.
4266 Tue Feb 5 21:39:35 1991 John Gilmore (gnu at cygint.cygnus.com)
4268 * command.c, dbxread.c, expprint.c, infcmd.c, infptrace.c,
4269 infrun.c, printcmd.c, remote-nindy.c, source.c, sparc-tdep.c,
4270 sparc-xdep.c, symfile.h, symmisc.c, utils.c, valprint.c: Lint
4271 (actually gcc -Wall).
4273 * dbxread.c: Remove first_global_sym, last_global_sym, since
4274 they are never referenced.
4276 * defs.h (baud_rate): Declare.
4277 main.c: Define it, and add the -b option to set it.
4279 * gdb-int.texinfo: Add text on how to define a new host or target
4280 architecture, prompted by Per Bothner's questions about MIPS
4283 * gdb.texinfo: Document "complaints". Change doc of -q since
4284 gdb no longer prints the copyright and blurb if you specify a file
4285 name to be debugged (just like Emacs). Add doc for Nindy-specific
4286 command line flags for specifying target serial port and such.
4287 Update copyright to 1991.
4289 * gdbcore.h: Remove a large mass of now-useless crud, since BFD
4290 has taken over for us the job of ripping up executable files. The
4291 crud caused Per Bothner's port to not compile.
4293 * infrun.c (normal_stop): Avoid printing "Program exited
4294 normally" if we are in batch mode. This allows a GDB which
4295 executes a program on a target system, to behave like a Unix
4296 command (input from stdin, output to stdout, no extraneous
4299 * main.c (main): Allow additional machine-dependent command line
4300 options to be specified with the ADDITIONAL_OPTIONS,
4301 ADDITIONAL_OPTION_CASES, ADDITIONAL_OPTION_HELP, and
4302 ADDITIONAL_OPTION_HANDLER macros. Also allow machine-dependent
4303 processing to occur just before the main loop with
4304 BEFORE_MAIN_LOOP_HOOK.
4305 (main): If a "core file" argument is specified, and it is not a
4306 core file, try it as a process ID to attach.
4307 (symbol_completion_function): Attempt to cope with
4308 "show screen-" TAB, not very successfully. This needs more work,
4310 (batch_file): New function, returns whether we are reading
4311 commands from an interactive tty on stdin, or from somewhere else.
4312 Called by normal_stop since it doesn't get from_tty passed down
4313 to it like many commands do.
4315 * remote-nindy.c: Handle command line options for nindy
4317 (nindy_before_main_loop): Prompt user for tty name if they
4318 don't specify it before getting to the interactive command loop.
4320 * tm-i960.c: Add ADDITIONAL_OPTIONS, etc, to handle -O, -brk,
4321 and -r command line options. Also add hook before main loop
4322 to make it easy to specify a tty.
4324 * TODO: More things to do, one done.
4326 Mon Feb 4 23:57:39 1991 John Gilmore and Mike Tiemann (at cygint.cygnus.com)
4328 * dbxread.c: Make complaint() calls pass pointer, not struct.
4329 Add complaints about badly formatted C++ type information
4330 (const/volatile indicator, and parse errors resulting in
4331 error_type). Fix C++ virtual member fn comment.
4332 (read_struct_type): Avoid bumping pointer if we got a parse
4333 error; this prevents our walking beyond the end of a string.
4334 Terminate loop on null char as well as semicolon.
4335 (process_one_symbol): Fix the LBRAC fix so that it uses the
4336 last previous SLINE, FUN, or SO record's PC address. C++ debug
4337 symbols did not have SLINE records in a useful order compared
4338 to the LBRAC records.
4339 (define_symbol): Handle "catch" records.
4341 * symtab.c (check_stub_type): Added new complain
4342 `stub_noname_complain' and added a consistency check to
4343 keep the debugger from crashing when finishing from an
4344 exception frame. A real fix will be needed later.
4346 Sat Feb 2 10:43:05 1991 John Gilmore (gnu at cygint.cygnus.com)
4348 * infcmd.c (attach_command): Make global.
4350 * Makefile.dist (REMOTE_OBS): Make these compile by default,
4351 but make them easy to comment out. Perhaps later they should
4352 be enabled by what CPU you configure for? FIXME.
4353 (VERSION): Roll to 3.93.
4354 (pinsn.o): Remove rule for obsolete file.
4355 (dbxread.o,coffread.o,mipsread.o): Use ${srcdir} explicitly.
4357 Run down a problem that manifested by printing the wrong function
4358 name in stack traces of read_ofile_symtab. Turned out that the
4359 problem was the SunOS 4.1.1 (and previous) C compiler outputs
4360 the LBRAC symbol with an address in the *data* segment, which
4361 blew our binary search through the blocks.
4363 * dbxread.c: Use the complain() facility consistently to bitch
4364 about problems in the symbol file we are reading.
4365 (finish_block): Add code to check the nesting of the blocks;
4366 complain and Procrust them to fit if wrong.
4367 (make_blockvector): Check the order of the blocks, complain
4368 [but don't cope] if wrong.
4369 (process_one_symbol): ifndef SUN_FIXED_LBRAC_BUG, check LBRAC
4370 symbols to be sure their PC value is greater than the last SLINE
4371 (line number) symbol we've seen, complaining and adopting the
4372 SLINE PC value if wrong.
4374 * symfile.h (struct complaint, complaint_root, complain,
4375 clear_complaints): Add.
4376 * symfile.c (complain, complaint_root, clear_complaints): Add
4377 facility to deal with non-fatal complaints and to regularize their
4379 (symbol_file_add): Clear complaint counters to allow new complaints.
4380 (initialize_symfile): Add 'set complaints' and 'show complaints'.
4382 * dbxread.c (dbx_symfile_read): Remember the address and size
4383 of the string table for the main symbol file, so we won't read it
4385 (dbx_psymtab_to_symtab): Fix the check for main symbol file,
4386 to avoid reading the string table yet again. Lint.
4387 (throughout): Improve filtered output, including word wrap.
4388 (read_range_type): Improve Bothner's fix to handle other types too.
4390 * utils.c: Improve line wrap implementation. Handle unlimited
4391 width by making chars_per_line unsigned.
4392 (puts_filtered): New, easy, function.
4394 * defs.h (puts_filtered): add.
4396 * mipsread.c (compare_symbols, sort_symtab): Remove these fns,
4397 call the identical sort_symtab_syms() in symfile.c instead.
4399 * expread.y: Suggest the `file' command rather than `symbol-file'.
4401 * command.h (enum var_types): Add zinteger for seroable
4403 * command.c (do_setshow_command): Handle var_zinteger. Restructure
4404 nested if's into a switch.
4406 * breakpoint.c (bpstat_print): If bpstat "print" flag is not set,
4407 we did not stop because of a breakpoint (it must have been for
4408 some other reason, like a "stepi"), so don't print anything.
4410 * symtab.c: Include <sys/types.h> all the time. Now that BFD
4411 doesn't include <sys/types.h>, old SunOS's require it for
4414 Sat Feb 2 10:39:15 1991 Per Bothner (bothner@cs.wisc.edu)
4416 A test port of gdb-3.92.6 to the Sony NEWS.
4419 Don't normally link in remote- or vx stuff.
4420 Some of it doesn't compile, and it wastes space for 99% of the users.
4421 Remove reference to no-longer-used HAVE_VPRINTF.
4422 Fixed BFD_DEP typo to BFD_DIR.
4424 Fix cast in arg to bfd_h_getlong.
4425 Make char *prefix be const.
4426 Fix how certain range types are mapped into builtin unsigned int types.
4428 Remove 2 #includes. They cause errors (on Sony, at least),
4429 and aren't needed (they wern't in earlier versions).
4431 print_address_symbolic should never demangle labels
4432 (since it prints *assembler-level* labels).
4434 [This was superseded by the change to printcmd below.]
4437 Add some "volatile" return types to avoid warnings.
4438 If MISSING_VPRINTF add vprintf function and not just macro
4439 (since vprintf is used in printcmd.c).
4441 Unless __GNUC__, use obstack_grow instead of obstack_ptr_grow.
4442 (The latter isn't grokked by some PCC-based compilers.)
4444 [This change is in abeyance, we prefer to fix obstack_ptr_grow.]
4446 Make chunk size of dont_print_obstack 32*4 instead of default 4096.
4447 * nindy-share/coffstrip.c
4448 Added some forward declarations (otherwise, gcc complains
4449 about implicit extern redefined as static).
4451 Sun Jan 20 02:38:19 1991 John Gilmore (gnu at cygint.cygnus.com)
4453 Changes inspired by Per Bothner:
4454 * printcmd.c (print_address_symbolic): Take additional parameter
4455 specifying whether to demangle.
4456 (print_address): Pass in asm_demangle to control demangling.
4457 (print_address_demangle): New fn, takes explicit arg to control
4459 * utils.c: Add new vars demangle and asm_demangle, and let them
4461 (fputs_demangled): If !demangle, just print the argument.
4462 (fprint_symbol): If !demangle, just print raw symbol.
4463 * valprint.c (val_print): Call print_address_demangle rather than
4464 print_address, to cause demangling to depend on the global
4465 rather than assembler-level demangling setting.
4466 * WHATS.NEW, gdb.texinfo: Document.
4468 * main.c (show_command): Show all settings if no arg.
4469 (initialize_main): Make "info set" the same as naked "show".
4470 * command.c (cmd_show_list): Handle prefix commands in the
4471 list, and print the name of the setting as well as its English
4472 description and value.
4474 Allow gdb functions to specify where a line should wrap if it
4475 exceeds the size of a terminal line. Use it to make the output
4477 * utils.c (set_screen_width_command): New fn, mallocs a buffer
4478 of the right size when screen width changes.
4479 (set_screensize_command, screensize_info): Remove #if 0'd fns.
4480 (wrap_here): New fn, indicates a point in the output where we
4481 should wrap the line rather than just letting it overflow at a
4483 (fputs_filtered): Implement wrapping.
4484 (n_spaces): New fn, returns a pointer to N spaces.
4485 (print_spaces_filtered): Use n_spaces.
4486 * defs.h (n_spaces): Declare.
4487 * stack.c (print_frame_info): Wrap with 4-space indent after
4488 fn name and before filename and line number.
4489 * printcmd.c (print_frame_args): Wrap with 4-space indent
4490 before each argument name is printed.
4491 * valprint.c (value_print): Wrap with no indentation before
4493 (val_print_fields): Wrap with indentation relative to nesting
4494 level before each field name.
4495 (val_print): Wrap with nesting indentation before array elements.
4496 * command.c (do_setshow_command): Avoid extra newlines,
4497 wrap with 4-space indent around values printed, end with period.
4498 * WHATS.NEW, gdb.texinfo, gdb-int.texinfo: Document.
4500 * breakpoint.c (breakpoint_1): Implement addressprint for
4501 "info breakpoints" display. Change file name and line number
4502 format to " at file:nnn" rather than " (file line nnn)".
4503 * gdb.texinfo: Document.
4506 Fri Jan 18 07:21:25 1991 John Gilmore (gnu at cygint.cygnus.com)
4508 Frozen for gdb-3.92.6 release.
4510 README, WHATS.NEW: Update for 3.92.6 release.
4512 tconfig/{altos, i386v, i386v32, m88k, umax}: Eliminate
4513 coffread.o from configs since it is now built by default.
4514 tconfig/{3b1, altosgas, arm, convex, hp300bsd, hp300hpux,
4515 i386v-g, i386v32-g, isi, merlin, news, news1000, np1, pn,
4516 pyramid, symmetry, vax, vxworks68}: Eliminate dbxread.o
4517 from configs since it is now built by default.
4519 Makefile.dist: Update for release 3.92.6. Handle files that
4520 have been moved to ../include, ../getopt, or ../bfd. Add
4521 saber.suppress and tests directory. Add config.status to
4522 the release (it will say "none").
4524 coredep.c: Minor formatting fixes.
4526 These changes were made in early December but only checked in now:
4527 * nindy-share/Onindy.c, nindy-share/coffstrip.c,
4528 nindy-share/nindy.c: lint
4529 * nindy-share/nindy.c (ninStopWhy): Don't byteswap the
4530 register values coming back from the target; we store values
4531 in target byte order everywhere.
4533 Wed Jan 16 19:01:37 1991 John Gilmore (gnu at cygint.cygnus.com)
4535 * am29k-opcode.h, am29k-pinsn.c: Add 29050 opcodes.
4537 * valprint.c (cplus_val_print, val_print_fields): New functions,
4538 which print C++ objects. They conspire to avoid printing a
4539 virtual base class more than once, following all the twists and
4540 turns of C++ virtual base rules.
4541 (val_print): Call the above rather than do it by hand.
4543 * symfile.c (symbol_file_add): Only reset symfile_mtime for main
4544 symbol file, not for added files like shared libs. This really
4545 needs to be generalized to a timestamp per file.
4547 * core.c (cleanup_core): Avoid coredump if no core file.
4549 * config.gdb: Accept -host or -target in place of +host or
4552 * coffread.c (find_linenos): Avoid desupported BFD interface
4553 to line numbers. We still read them manually rather than using
4554 BFD's "generic" features.
4556 * gdbrc.tex, threecol.tex: Add GDB reference card and its
4558 Makefile.dist: Add refcard to OTHERS list for creating tar files.
4560 * Makefile.dist: Eliminate use of $< in explicit targets.
4562 * readline/Makefile: Use $< rather than $*.c, which does not
4563 include the VPATH in GNU Make.
4565 * tconfig/i960-bout, tconfig/i960-coff: These are identical
4566 copies of tconfig/i960, added for global configuration
4567 compatability. All i960 versions can read both coff and b.out.
4569 * tm-88k.h: Fix multiline macro that lacked \'s. Remove
4570 COFF_FORMAT and COFF_CHECK_X_ZEROES since these are now handled
4573 * TODO: Think of more things to do.
4575 Wed Jan 2 19:09:29 1991 John Gilmore (gnu at spiff.cygnus.com)
4577 tconfig/{am29k,i960,sun2*,sun3*,sun4*}: Eliminate config
4578 of sdb versus dbx debug symbols. Add kludge for 68881 80-bit to
4579 64-bit float conversion.
4581 tconfig/sun4, tconfig/sun3, xconfig/sun4, xconfig/sun3: Make
4582 equivalent to sun?os4 so global config works.
4584 Wed Jan 2 18:20:51 1991 John Gilmore (gnu at spiff.cygnus.com)
4586 Fix from Eberhard Mattes <mattes@azu.informatik.uni-stuttgart.de>
4588 * main.c: Only declare linesize once; declare pagesize not at
4589 all, since it is never used.
4590 (main): Clear newly allocated line before it is used.
4592 Fri Dec 28 00:13:42 1990 John Gilmore (gnu at cygint)
4594 Further stabilization for the Intel 960.
4596 * Makefile.dist: Parameterize the location of the "include"
4597 and "bfd" directories, as well as "getopt". Add symfile.c.
4598 Link in both dbxread and coffread. Fix up "make depend" to
4599 rewack the locations of include, bfd, and getopt in its output.
4601 * README: Document moving include files, improve some of
4604 * coffread.c: Move common code out to symfile.c. Change
4605 symbol_file_command style interface to use new *_symfile_init
4606 and *_symfile_read interface under BFD. Use BFD internal
4607 info to locate line table, symbols, etc.
4609 * core.c (core_fetch_registers): Rename to get_core_registers
4610 to avoid confusion with fetch_core_registers.
4611 (register_addr): Move to coredep.c, which is already machine
4612 dependent. This leaves core.c pretty clean of dependencies.
4614 * coredep.c (register_addr): Accept this routine from core.c.
4616 * dbxread.c: Move common code (with coffread.c, etc) into new
4617 symfile.c. Each psymtab now contains a pointer to the
4618 format-dependent function that knows how to read it in. Make
4620 (dbx_psymtab_to_symtab): Renamed from psymtab_to_symtab_2.
4621 (process_one_symbol): Add code to complain about a "compiler bug
4622 we muzzle here", if we actually see it.
4624 * eval.c (evaluate_subexp): Insert missing "break" statements
4625 in code that determines whether a variable is an lvalue in
4626 memory, register, or whatever. I detected this via a compiler
4627 bug in which it *almost* mashed out the whole switch statement.
4629 * gdb-int.texinfo: Add minor sections on configuring gdb for
4630 release, and about the README file.
4632 * infcmd.c (registers_info): Fix formatting somewhat. Still
4633 not as pretty as before, but it handles byte swapping.
4635 * remote-nindy.c: If data cache routines are interrupted while
4636 waiting for the remote end, be sure that any uninitialized cache
4637 blocks are on the free list, not on the valid list!
4639 * symfile.h: Flesh out this header file with all the various
4640 routines and variables that have been merged in from dbxread.c
4641 coffread.c, and symtab.c to symfile.c.
4643 * symfile.c: New file, containing code common to dbxread.c,
4644 coffread.c, and some code from symtab.c. All generic code for
4645 reading symbol files should be in here now.
4646 (unrecord_misc_function): Remove unused function.
4648 * symtab.h: Remove file-reading things to symfile.h.
4650 * symtab.c: Remove file-reading things to symfile.c.
4652 * tm-i960.h: Fix FRAME_CHAIN types; define PRINT_RANDOM_SIGNAL
4653 to decode i960 fault types.
4655 * target.h, remote.c, remote-eb.c, remote-vx.c, remote-nindy.c,
4656 target.c: Change type of the "resume" function from int to void,
4657 since its result was never used.
4659 Sat Dec 22 02:51:40 1990 John Gilmore (gnu at cygint)
4661 * main.c: Replace "stupid" with "caution"; you now "set caution
4664 * printcmd.c (print_scalar_formatted): Fix typo in 'g' format
4666 * infcmd.c (do_registers_info): Call val_print to deal with the
4667 byte order of the registers being printed. FIXME, this makes
4668 the formatting of the output uglier.
4670 * infcmd.c (wait_for_inferior): If PRINT_RANDOM_SIGNAL is
4671 defined, call it for signals the debugger doesn't itself use.
4672 The i960 uses this for more detailed fault information.
4674 * remote.c (remote_open): If arg is null, print help rather than
4677 * sparc-xdep.c (register_valid): Avoid declaring size, since
4678 various modules will think of various sizes depending on the
4679 architecture of their tm-file. FIXME, we need protection against
4680 actually entering one of those modules, which would clobber
4681 storage if not for the target architecture compiled into gdb.
4683 * stack.c (up_command, down_command): Always print the frame
4685 (up_silently_command, down_silently_command): New commands
4688 * i960-pinsn.c (reg), i960-tdep.c: Lint.
4690 * i960-tdep.c (i960_frame_chain_valid): Lookup_symbol now takes
4691 more parameters than it used to.
4693 * findvar.c (registers): Increase slop to 256 bytes, which should
4694 protect us against even most RISC machines with large register
4696 (locate_var_value): Move declaration inside related ifdef.
4698 * remote-nindy.c (): Use TIOCSETN rather than TIOCSETP
4699 throughout, to avoid throwing away buffered input from the board.
4700 (nindy_wait): Supply_register takes addr_of_value, not value.
4701 (i960_print_fault): Renamed from i80960_fault.
4702 (nindy_fetch_registers): Avoid have_regs stuff, just get them.
4703 (nindy_store_registers): Avoid regs_changed stuff, just stuff
4705 (nindy_create_inferior): Don't bother to write PC_REGNUM since
4706 we can set the PC in the call to proceed(). Unpush nindy_ops
4707 before pushing it on top, to avoid message to user. Eliminate
4708 commentary from Unix machines that just misleads here.
4709 (reset_command): Fix error message to suggest target command.
4711 Wed Dec 19 11:03:56 1990 John Gilmore (gnu at cygint)
4713 Release 3.92.5 as frozen.
4715 Stabilize the merged release...with help from lint, Saber C,
4718 Everywhere: Add include files needed to declare return types
4719 of functions called.
4721 * gdb.texinfo: Roland Pesch is documenting gdb, glory be!
4723 * breakpoint.h: Add undeclared breakpoint functions, and some
4724 functions for display handling since I couldn't think of a better
4727 * breakpoint.c (insert_breakpoints): Make code for disabling
4728 shared library bkpts more likely to work. It's used when we
4729 rerun a program and stop before the shared library has been
4731 (breakpoint_cond_eval, bpstat_stop_status): Pass arg as int,
4732 cast from pointer, so it squeezes through catch_errors.
4733 (bpstat_stop_status): Fix logic broken some time ago. We now
4734 always create a bpstat if the stop address matches a breakpoint,
4735 even if we don't stop there -- just like the old code used to do
4736 before I got my fingers into it (sigh).
4737 (breakpoint_1): Print "ignore count" after "stop only if"
4738 condition, since that's how it actually works.
4739 (mention): Handle watchpoints as well as breakpoints.
4740 (watch_command): use set_raw_breakpoint and mention to do most
4741 of the work (and initialize all the fields!). Only pass one
4742 arg to parse_c_expression, since that's all it takes.
4744 * command.c (not_just_help_class_command): Rename arg to args
4745 since we ignore "unused argument" warnings on vars named "args".
4746 inflow.c (child_terminal_info): ditto.
4747 infptrace.c (kill_inferior): ditto
4748 main.c (catch_errors, version_info, quit_command, pwd_command,
4749 source_command, dump_me_command, editing_info,
4750 set_history_size_command, set_history, show_history,
4752 stack.c (locals_info): ditto
4753 target.c (target_files_info): ditto
4754 valprint.c (set_input_radix, set_output_radix): ditto
4756 * core.c: Remove old variables for handling core and exec file
4757 sections (data_start, data_end, stack_start, stack_end,
4758 reg_stack_start, reg_stack_end, reg_stack_offset, text_start,
4759 text_end, exec_data_start, exec_data_end, text_offset,
4760 exec_data_offset, data_offset, stack_offset). They're
4761 superseded the more general build_section_table and
4763 (get_exec_file): Mention the `file' command.
4764 (read_memory_check): Rename to memory_error, and only call it
4765 in the case of an actual error.
4766 (read_memory, write_memory): call memory_error.
4767 (core_fetch_registers): Register section name is ".reg".
4769 coredep.c: Remove a bunch of crud now that all this file does
4770 is pull the registers out of a core file.
4771 (fetch_core_registers): Rewrite to actually work, I hope.
4773 dbxread.c: Use a.out.gnu.h, not system a.out, now.
4774 Replace index() with strchr(). Remove all the pre-BFD macro
4775 definitions for accessing the symbol file.
4776 (struct dbx_symfile_info): Encapsulate the information that
4777 dbx_symfile_init needs to pass to dbx_symfile_read in this
4780 (dbx_new_init, dbx_symfile_init, dbx_symfile_read,
4781 dbx_symfile_discard): Rearrange symbol file reading to divide
4782 the format-specific part from the format-independent part,
4783 leaving the format-independent part such as file name expansion
4784 and opening in symtab.c. This replaces
4785 partial_symbol_file_open and partial_symbol_file_read.
4786 Symbol_file_read, add_file, add_file_target_command,
4787 add_file_addr_command move to symtab.c. Pass an explicit
4788 "mainline" flag for when reading the main symbol table, rather
4789 than relying on the offset address to be zero or nonzero.
4791 (dbx_symfile_read): Don't allow void *'s to be printed as
4793 (SWAP_SYMBOL): Use bfd routines to byte-swap the symbols.
4794 (ADD_PSYMBOL_TO_LIST): Make the "function call rather than
4795 macro" debug version really work.
4796 (read_dbx_symtab): Remove unref'd parameter inclink.
4797 Avoid swapping N_SLINE symbols, for speed.
4798 Merge N_TEXT!N_EXT case with the other external symbol
4799 definitions' case. Add comments.
4800 (start_psymtab): Allocate the symfile name in the psymtab on
4801 the psymbol_obstack, rather than using the caller's storage.
4802 (end_psymtab): Only allocate a dependencies list if there are
4804 (psymtab_to_symtab_2): Use BFD when reopening file to read
4805 its symbols for real.
4806 (read_struct_type): Add FIXME comments where it needs work
4808 (read_huge_number): Add FIXME about overflows.
4809 (read_range_type): Add FIXME about comparing a long to 1<<32.
4811 * coffread.c: Minor changes to move things closer to the new
4812 regime with symtab.c and dbxread.c Major work is still needed
4815 * exec.c (exec_file_command): Remove old variables (see core.c
4817 (xfer_memory): If memory transfer is right at the end of a
4818 section, don't lose.
4820 * findvar.c (get_saved_register): If value is in a real
4821 register, LVAL is lval_register, not lval_memory.
4823 frame.h: Declare print_sel_frame and record_selected_frame.
4825 gdb-int.texinfo: New file, for GDB internals documentation.
4826 Very simple, unformatted doc of cleanups is there for now.
4828 gdbcore.h: Remove obsolete variables that described a.out
4829 section addresses and offsets. (See core.c above.)
4830 Declare fetch_core_registers and registers_fetched.
4832 getopt.c: Declare char *alloca(); even on SPARC.
4834 infcmd.c (run_command): Call target_kill rather than
4836 (step_command, next_command, stepi_command, nexti_command):
4837 Declare from_tty parameter even though we don't use it.
4838 (run_stack_dummy): argument BUFFER is a char array, not
4839 a pointer to REGISTER_TYPE.
4840 (finish_command): using_struct_return needed a value *,
4841 not a struct symbol *.
4843 * infptrace.c (child_xfer_memory): To avoid dependency on
4844 where sections are in memory, try PT_WRITE_D and if that fails,
4845 try PT_WRITE_I. Most Unixes don't care which you use.
4847 * infrun.c (step_resume_break_shadow): Change to array to
4848 match other breakpoint shadow storage.
4849 (clear_proceed_status): Pass address of bpstat to
4850 bpstat_clear, not the bpstat itself.
4851 (child_create_inferior): FIXME comment about if the child
4853 (start_inferior): Remove old function.
4854 (child_open): Use target_kill rather than kill_inferior.
4855 (wait_for_inferior): Ditto.
4856 (insert_step_breakpoint, remote_step_breakpoint): Use
4857 new step_resume_break_shadow.
4859 * inftarg.c (child_wait): If all child processes die,
4860 pretend that the one being waited for exited with signal 42.
4862 * main.c (command_line_input): When scanning for comments,
4863 don't coredump on unclosed quotes.
4864 (quit_command): Use target_kill rther than kill_inferior.
4865 (_initialize_main): Rename class_user from "user" to
4868 * printcmd.c (print_command_1): Initialize "fmt" if no format
4869 is specified by the user.
4870 (print_frame_args): Only add to args_printed if we are
4871 actually fetching args from the stack (avoiding undefined
4873 (_initialize_printcmd): Remove bogus \{ from string.
4875 * remote-eb.c (eb_open): Avoid coredump on no argument.
4877 * remote-nindy.c: Bring out of Intel environment into new
4878 target environment. Remove all conditional compilation on
4879 I80960. Massive hacking throughout.
4880 (nindy_xfer_inferior_memory): New routine stolen from
4882 (nindy_create_inferior): New routine pieced together, probably
4883 not quite working yet.
4884 (nindy_ops): New target_ops struct for nindy.
4886 * remote-vx.c: Use write_memory rather than target_write_memory
4887 to get error checking.
4888 (vx_add_file_command, vx_open): Use symbol_file_add rather than
4890 (vx_create_inferior): Use target_terminal_ours...
4892 * signame.c (_initialize_signame): Always initialize, since
4893 we need the table for things other than psignal.
4895 * solib.c (solib_add): Use symbol_file_add, not add_file.
4896 (solib_address): Return boolean result rather than struct
4897 pointer which nobody else knows the type of.
4899 * sparc-tdep.c, valops.c: Use write_memory rather than
4900 target_write_memory, to get error checking.
4902 * stack.c (locals_info, catch_info, args_info,
4903 get_selected_block, frame_command, up_command): Use
4904 target_has_stack, rather than have_inferior_p or
4907 * sun3-xdep.c (fetch_core_registers): Rewrite for new BFD regime.
4909 * symfile.h: New file, defining the interface between the
4910 generic and object-file-specific symbol reading code.
4912 * symtab.c: Move generic symbol-reading interface to symtab.c,
4913 from dbxread.c, coffread.c, mipsread.c, etc. Add symtab_fns
4914 table to map BFD targets to symbol-reading modules in GDB.
4915 Change index to strchr.
4916 (lookup_struct_elt_type): Use error() rather than hand-made
4917 simulations thereof.
4918 (lookup_partial_symbol): Speedup slightly when length == 0.
4919 (symbol_file_add): New function.
4920 (symbol_file_command): Call it.
4921 (symfile_open, symfile_init): New function.
4922 (add_file_target_command, add_file_addr_command): moved from
4925 * target.c (target_command): use target_kill.
4927 * target.h (target_files_info): Don't declare, never called
4930 * tm-sun2.h, tm-sun3.h (STACK_END_ADDR): Use system include
4931 files to determine stack end address.
4933 * valarith.c (value_x_binop, value_x_unop): Change error message
4934 to be more useful. Pass proper argument to value_struct_elt.
4936 * valops.c (value_assign): FIXME comment that long long
4937 bitfields will break here.
4939 * Makefile.dist: Add symfile.h, remote-nindy.c, remote-eb.c.
4940 Update `make saber_gdb' to work better.
4942 * TODO: A woman's work is never done.
4944 * cplus-dem.c, environ.c, inferior.h, infrun.c, inftarg.c,
4945 main.c, obstack.c, printcmd.c, remote-eb.c, remote-nindy.c,
4946 remote-vx.c, remote.c, solib.c, source.c, sparc-pinsn.c,
4947 sparc-tdep.c, sparc-xdep.c, symmisc.c, symtab.c, symtab.h
4948 target.c, terminal.h, tm-sparc.h, tm-sunos.h, utils.c,
4949 valops.c, valprint.c, exec.c: Lint.
4952 Wed Dec 12 23:44:15 1990 John Gilmore (gnu at cygnus.com)
4954 Continuing Intel 960 port merge of GDB.
4956 * Makefile.dist: Merge i960 "nindy-share" files. Rename
4957 malloc.h to gmalloc.h to avoid name conflicts in /usr/include.
4958 Don't ship gdb.dvi in tar file. Link gdb with init.o, not init.c.
4959 Wack over "make depend" so it handles files in subdirectories
4960 vx-share, nindy-share, bfd, and in the current directory.
4962 * blockframe.c (get_prev_frame_info): Remove fatal error
4963 if stack not defined.
4965 * core.c (core_open, core_detach): New functions that handle
4966 the old "core-file" command as "target core" and "detach" instead.
4967 (core_file_command): Call them.
4968 (core_xfer_memory): Use common routine xfer_memory.
4970 * dbxread.c: Include a.out.gnu.h, not system a.out.h.
4971 dbxread now uses bfd for everything but symbol reading itself.
4972 BFD internals are used to drag out the relevant file offsets.
4973 (partial_symbol_file_open): Change args all around for BFD.
4975 * symtab.c: Rename "value" to "val" everywhere, so we can
4977 (symbol_file_command): New command, moved from dbxread.c
4978 and coffread.c. It uses BFD to read the file, then vectors
4979 based on its type, to dbx or coff symbol readers.
4980 * symtab.h: Extern a few vars for symbol_file_command.
4982 * target.h: Breakpoint takes a char * save area, not a char **.
4984 * valprint.c (val_print): When unpacking bitfields, offset
4985 the address in gdb of the value, if it is declared with a shorter
4986 type. Remove the last "runtime kludge test" of host byte order.
4988 * utils.c: Remove old my_bfd_read routine.
4990 * stack.c (frame_info): Use target_has_stack. Print program counter
4991 register's actual name rather than "pc", since it's called the
4992 "ip" (instruction pointer) on the i960 (sigh).
4994 * target.c (target_command): Add command for selecting a target
4995 type and calling its open routine. This is used for initiating
4996 communication with a particular target, in a generic way.
4998 * tm-i960.h: Update for modern gdb. Remove semicolons from
4999 various macros. Handle reading struct return convention, and
5000 error-out attempts to return structs with the "return" command.
5001 Be sure gdb doesn't think we know how to call functions in the
5004 * i960-tdep.c: Rename FRAME_CHAIN_VALID and FRAME_FIND_SAVED_REGS
5005 to i960_xxx in lower case.
5006 (arg_address): Circumvent errors due to LOC_ARG_BLOCK
5007 not being defined yet.
5009 * remote.c (remote_open): Call start_remote to initialize
5010 wait_for_inferior during open.
5011 (remote_xfer_inferior_memory): Return length written rather
5014 * remote-vx.c (target_command -> vx_open): Use new generic
5016 * remote-eb.c, inftarg.c, exec.c: ditto.
5018 * infrun.c: Fix comments.
5019 (attach_program -> child_open): Use new generic target command.
5020 (wait_for_inferior): Clear saved register values before target_wait,
5021 so target_wait can set some of them if convenient.
5023 * infptrace.c (fetch_inferior_registers, store_inferior_registers):
5024 Return success indicator, not void.
5025 (child_xfer_memory): Avoid fetching initial word if we'll
5026 overwrite it anyway.
5028 * infcmd.c (attach_command): Use new generic target open routine.
5029 (_initialize_infcmd): Update doc on attach and detach commands.
5030 (do_registers_info): Merge in a byte-order problem as a FIXME
5033 * findvar.c (find_saved_register): Avoid problem in current frame.
5034 (read_relative_register): Ditto.
5035 (write_register): Convert byte order on the way out.
5037 * exec.c (file_command): Add.
5038 (add_to_section_table, exec_command): Use new bfd_map_over_sections.
5039 (xfer_memory): Common function between core_xfer_memory and
5041 (exec_xfer_memory): Use it.
5043 * pn-opcode.h: Document that a "PN" is a Gould PowerNode.
5045 * breakpoint.c, breakpoint.h, symtab.h, value.h, frame.h, utils.c,
5046 valops.c, stack.c, target.c, sparc-xdep.c, source.c, printcmd.c,
5047 infcmd.c, i960-pinsn.c, eval.c, defs.h: lint and gcc -Wall.
5049 Sun Dec 2 16:45:06 1990 John Gilmore (gnu at cygnus.com)
5051 Merge Intel 960 port of gdb, continuing...
5053 * dbxread.c (partial_symbol_file_open, partial_symbol_file_read,
5054 symbol_file_command): Pass from_tty arg to hush 'em up.
5056 * coffread.c (symbol_file_command): Avoid output if from_tty != 1.
5057 Add magic numbers for 960 COFF format.
5059 Fri Nov 30 09:18:20 1990 John Gilmore (gnu at cygnus.com)
5061 Merge Intel 960 port of gdb, from Intel "1.2" release.
5063 CHANGE_LOG entries from their port, which was based on
5066 Thu Sep 6 11:02:22 PDT 1990
5067 Remove temp file if download is interrupted.
5069 Wed Aug 1 09:08:33 PDT 1990
5070 Now uses binary protocol to talk to NINDY.
5071 Old hex protocol (NINDY 2.13 and older) supported with -O switch.
5072 Times out after 5 seconds when trying to talk to NINDY.
5074 Tue May 29 12:54:49 PDT 1990
5075 Added variable baud rate (-b switch).
5076 Source code reorganization.
5078 Thu Apr 26 11:09:55 PDT 1990
5079 More cleanup of batch mode; specifically, execute "-s", "-e", and
5080 "-se" switches as soon as they are encountered on the invocation line.
5082 Fri Apr 20 13:47:15 PDT 1990
5085 Thu Apr 19 09:54:28 PDT 1990
5086 Add 'reset' command.
5088 Wed Apr 18 09:48:07 PDT 1990
5089 After opening remote tty, wait for 1 second to go by without input
5090 from it before trying to talk to NINDY (fixes problems with the
5091 Heurikon HK80/V960E).
5093 Mon Apr 4 16:33:05 PDT 1990
5094 Some output was not being suppressed in 'batch' mode.
5096 Thu Mar 22 15:31:11 PST 1990
5097 Ask user if old symbol table should be deleted when new file is
5100 Allow user to run a program downloaded before gdb960 was brought up.
5102 Correct "exec-file" help message for i80960 context.
5104 Correct bug in calculating user space address: could occasionally
5105 corrupt user program.
5107 Make sure to zero low-order bits in rip's because of bug in 960CA
5108 A-step part: could cause operation faults when "next"ing across
5111 Correct bug that made it impossible to get source line numbers for
5112 code loaded at addresses higher than 0x7fffffff.
5114 Wed Jan 10 12:43:22 PST 1990
5115 Open remote tty for exclusive use.
5117 Fri Jan 5 12:14:42 PST 1990
5118 Correct disassembly (CA manual was right after all):
5119 opcode for sysctl is 0x659
5121 Mon Oct 23 12:03:04 PDT 1989
5122 Use G960BASE and G960BIN environment variables to find 'sx' utility.
5124 Mon Oct 16 14:15:09 PDT 1989
5125 "sfr0"-"sfr31" should have been named "sf0"-"sf31"
5127 Mon Oct 2 15:56:31 PDT 1989
5129 Added 960CA disassembly support.
5131 To simplify maintenance:
5132 - eliminated use of symblic links on pinsn.c: use i960-pinsn.c
5134 - eliminated opcode.h: incorporates tables into i960-pinsn.c
5135 - moved 960-specific routines from i960-pinsn.c to i960-md.c
5136 - made disassembly interface identical to that in gdmp960.
5140 Wed Nov 28 21:32:48 1990 John Gilmore (gnu at cygint)
5142 * target.h: Allow targets to stack. Add target_has_memory,
5143 _registers, etc. Restructure memory access and "info files"
5144 to walk the target stack.
5145 * exec.c, core.c, inftarg.c, remote.c, remote-vx.c, remote-eb.c,
5146 target.c: Change tables to match target.h.
5147 * inflow.c (child_mourn_inferior): pop child_ops.
5148 (generic_mourn_inferior): Use new has_stack flag.
5149 * infptrace.c (child_xfer_memory): New memory regime.
5150 * inftarg.c (child_files_info): New "info files" regime.
5151 * remote-eb.c: New memory regime, new info files.
5152 * remote-vx.c: New memory regime, new info files. Now use
5153 separate targets for VxWorks attachment to machine, and
5154 actually running a process under VxWorks, since one has
5155 stack & execution & regs and the other doesn't.
5156 * remote.c: New memory regime, new info files.
5157 * sparc-xdep.c (fetch_core-registers): New memory regime.
5158 * target.c: New routines and support for stacked targets,
5159 new memory regime, new info files regime.
5162 Generalize section handling for an arbitrary number of sections,
5163 including use of the new BFD (binary file) library.
5164 * gdbcore.h: Add struct section_table.
5165 * exec.c (build_section_table): Iterate all sections and
5166 record what gdb needs to know about them.
5167 (exec_command): Use it.
5168 (exec_xfer_memory): Use the table.
5169 (exec_files_info): Print the table.
5170 * core.c (core_file_command, core_xfer_memory, core_files_info):
5172 * source.c (find_source_lines): Use bfd_get_mtime.
5173 * dbxread.c: Quick changes to make it compile with new BFD.
5174 * utils.c (error): Avoid using bfd_error in generic routines.
5176 * core.c (core_fetch_registers): Get from the ".regs" section of
5178 * sparc-xdep.c (fetch_core_registers): Use the .regs info.
5180 * inferior.h (attach_flag): Export.
5181 * infcmd.c (run_command): use new target_create_inferior.
5182 * infrun.c (child_create_inferior): Don't return result.
5183 * Makefile.dist (VERSION): 3.91.4.
5185 Fri Nov 23 28:15:38 1990 John Gilmore (gnu at cygint)
5187 * breakpoint.c (bpstat_num): Handle breakpoints which have
5188 since been deleted, such as temporary breakpoints.
5189 infcmd.c (program_info): ditto.
5191 * core.c (core_file_command): Display the frame where the core
5196 * remote-vx.c (target_command): Merge in target command from
5197 targ-vx.c. A few other cleanups.
5199 * TODO, Projects: Lots more stuff to do...
5201 Fri Nov 23 18:15:38 1990 John Gilmore (gnu at cygint)
5203 Massive changes to wall off the remote-debugging interface
5204 behind a function vector. The port to handle VxWorks targets
5205 is also part of this.
5207 All files: Replace references to renamed functions,
5208 remove references to remote_debugging, remove references to
5209 have_include_file, have_core_file in favor of target_has_stack,
5210 target_has_memory, etc.
5212 * Modularize the breakpoint interface.
5213 breakpoint.h (BREAKPOINT_MAX): New define sets max length of
5214 a breakpoint instruction.
5215 breakpoint.c: struct breakpoint's shadow_contents now sized as
5217 (insert_breakpoints): Vector to target to install breakpoints.
5218 (remove_breakpoints): Vector to target here too.
5219 Remove REMOTE_SA_SPARC kludges and other remote_debugging.
5220 sparc-tdep.c (single_step): Use new breakpoint interface for
5221 the single-step breakpoints.
5222 mem-break.c (memory_insert_breakpoint, memory_remove_breakpoint):
5223 New file, contains routines to insert and remove breakpoints by
5224 reading out the old contents and later replacing them. This is
5225 how ptrace breakpoints work, and many remote systems as well.
5227 * tm-vxworks68.h: New config file, overrides a few things for
5228 Wind River's preferences.
5230 * target.h: New file, for transfer vector used to talk to the
5231 inferior (child, attached, core, exec, remote, etc). All accesses
5232 to the thing being debugged should come through these vectors.
5233 target.c: New file, routines to handle transfer vector.
5234 (various files): Add transfer vectors XXX_ops for the various
5235 targets and pseudo-targets (core files, etc) we support.
5237 * breakpoint.c (bpstat_stop_status): Further explorations of
5238 watchpoints and why things don't work all the time.
5239 (bpstat_alloc): New fn to allocate a bpstat and chain it.
5241 * config.gdb: Only add "source ${srcdir}/.gdbinit" to
5242 the local gdbinit if it doesn't already have it.
5244 * core.c (core_ops): add and install.
5245 Allow core debugging without exec file.
5247 * dbxread.c (free_and_init_header_files): Merge two fns.
5248 (end_symtab): Free named symbol table when a new version comes in.
5249 (read_dbx_symtab): Relocate all kinds of symbols with base
5250 address. First step toward handling different text, data, bss
5252 (add_file_addr_command): Renamed add_file_command.
5253 (add_file_command): Vector to remote handler.
5254 Add "load" as an alias for "add-file" command.
5256 * defs.h: Allow "volatile" to be used in non-ANSI; use it for
5257 non-returning functions.
5259 * exec.c: Add exec_ops, and push it as a target when an exec
5262 * infcmd.c (run_command): Pass executable file name and arg list
5263 separately when starting an inferior. Permit "run" when no exec
5264 file is specified, for VxWorks.
5265 (detach_command): Move to child_detach in inftarg.c.
5267 * inftarg.c: New file. Unix-child-specific routines, and the
5268 child_ops structure.
5270 * inferior.h (registers): Export "registers" as the way for
5271 target dependent register handlers to find gdb's local copy of
5272 the registers. Rename "stop_after_attach" to "stop_soon_quietly"
5273 since it is now used by places that want wait_for_inferior to
5274 handle the grunge but want to see every trap from the inferior.
5276 * inflow.c (create_inferior): Pull out, and merge into infrun.c.
5277 Eliminate remote_debugging hooks in terminal handling.
5279 * infrun.c: Replace start_inferior with child_create_inferior.
5280 Move all the hair of Unix shells and ptrace idiosyncracies into
5281 child_create_inferior, so remote handlers don't have to deal.
5282 Remove running_in_shell. Rename stop_after_attach to
5283 stop_soon_quietly, and use it in a few other places where we want
5284 to just call wait_for_inferior and get control back on the first
5285 trap. trap_expected now never takes a value > 1.
5286 (init_wait_for_inferior): Initialize static vars when a new
5289 main.c (gdbinit): Add new hook for .gdbinit file name, let
5290 it be overridden by config files as GDBINIT_FILENAME.
5291 (DEFAULT_PROMPT): Add new hook for overriding (gdb) prompt.
5292 Both of these are used for VxWorks gdb.
5294 mcheck.c: rename include file "gmalloc.c" to avoid problems
5295 with system include file "malloc.c".
5297 param-no-tm.h: New include file, same as param.h but does not
5298 include the default "tm.h" file. This is used in files where
5299 the target is known, e.g. remote-eb.c or sparc-xdep.c.
5301 param.h: Now just a shell that includes tm.h and param-no-tm.h.
5303 remote-vx.c: New file, VxWorks remote debugging support. Uses
5304 RPC routines that are shared with the target system, in directory
5307 remote.c: Vectorize remote interface.
5309 source.c: Globalize source_path, and make an alias "l" for "list"
5310 since we now have the "load" command.
5312 sparc-xdep.c: Use new param-no-tm.h.
5314 symmisc.c (free_named_symtab): Add new function from Wind River.
5315 However, ifdef it out for now while we think about what it should
5318 tm-sun3.h, xm-sparc.h, xm-sun3.h, xm-symmetry.h: Move
5320 the xm- file, and change its name to CHILD_PREPARE_TO_STORE, since
5321 non-Unix-children handle this with their own code in the target
5324 Makefile.dist: Roll version to 3.92.3. Add vx-share stuff to
5325 source and target lists. Add vx-share to default list of include
5326 directories. Add new files to src and target lists: mem-break,
5327 target, inftarg, remote-eb, remote-vx, targ-vx. Be sure the
5328 ${srcdir} versions of munch and createtags are used.
5330 * valops.c (find_function_addr): Split out of call_function.
5331 (call_function_by_hand): Rename call_function; this function
5332 calls functions in the target by laboriously patching the target
5333 word-by-word with the right stack, args, regs, etc.
5336 Mon Nov 5 17:29:10 1990 John Gilmore (gnu at cygint)
5338 Handle AMD 29000 a bit better.
5340 * remote-eb.c (readchar): Mask received char log to make it readable.
5341 (remote_start): Pass arguments down to executing program.
5342 Make startaddr unsigned.
5343 infrun.c (start_inferior): Accept args, pass them to
5345 infcmd.c (run_command): Pass args down to start_inferior.
5347 * tconfig/am29k-aout, tconfig/am29k-coff: New files specifying
5348 the target object file format.
5349 tm-29k.h: Pay heed to COFF_ENCAPSULATE.
5351 * am29k-pinsn.c (print_insn): Print 0x on hex numbers in disassembly.
5352 am29k-tdep.c (examine_prologue): Better checking of function prefixes.
5354 Sun Oct 7 18:20:45 1990 John Gilmore (gnu at cygint)
5356 * Makefile.dist (VERSION): Roll version to 3.91.9 and freeze.
5357 * TODO: We did a few things, we have more to do though.
5359 * xm-sparc.h (CLEAR_DEFERRED_STORES): Define.
5360 * inflow.c (inferior_died): Clear deferred stores.
5362 * Debug problems with dummy frames and calls to the inferior.
5363 * tm-sparc.h (PUSH_DUMMY_FRAME, POP_FRAME): Move to sparc-tdep.c.
5364 * sparc-tdep.c (do_restore_insn): Simplify.
5365 (sparc_frame_find_saved_regs): Simplify and fix what we find.
5366 (sparc_push_dummy_frame): Simplify and fix what we push.
5367 (sparc_pop_frame): Slightly more hair here, deciding whether
5368 we are restoring a saved PC or returning to a return address in %i7.
5369 * sparc-xdep.c (read_inferior_registers): Debug if valid reg is read.
5371 * utils.c (xmalloc, xrealloc): Return type depends on __STDC__.
5372 * symtab.h (xmalloc): ditto, for obstack_chunk_alloc.
5373 * obstack.h (chunkfun): ditto.
5374 * defs.h (xmalloc, xrealloc): ditto
5376 * utils.c (quit): Grab the terminal from the child if necessary.
5378 * inflow.c (term_status_command): Rename to term_info, change
5381 * sparc-pinsn.c (print_insn): Disassembly prefers real instructions.
5382 (is_delayed_branch): Speed up.
5383 * sparc-opcode.h: Add ALIAS bit to aliases. Fix up opcode tables.
5384 Still missing some float ops, and needs testing.
5386 * Support for input and output radixes other than base 10
5387 * defs.h (input_radix, output_radix): Declare.
5388 * expread.y (yyparse, parse_number): Handle changes of input
5389 radix, and ambiguous names-or-numbers in radixes >10.
5390 * printcmd.c (print_scalar_formatted): Print formatted hex
5391 numbers in varying column widths.
5392 * valprint.c (val_print): Use output_format to print scalar ints.
5393 (set_input_radix, set_output_radix, set_radix): Create.
5394 (set_output_radix): Set output_format from output_radix.
5395 (_initialize_valprint): add `set radix' but leave the others off.
5397 * main.c (execute_command): Let stupid questions be turned off.
5398 (_initialize_main): Handle "set stupidity", etc.
5400 * main.c, inflow.c, inferior.h, frame.h, command.c, defs.h,
5401 sparc-pinsn.c, sparc-xdep.c, value.h, valops.c, values.c: Lint.
5403 Tue Oct 2 11:20:02 1990 John Gilmore (gnu at cygint)
5405 * TODO, Makefile.dist, ChangeLog: Freeze for 3.91.8 release.
5406 bfd stuff is still screwed up, but with some manual work, it
5409 * breakpoint.c (bpstat_do_actions): Start over if a command
5410 proceeds the inferior, since the inferior will have stopped and
5411 will need to have its new stop-actions taken care of.
5413 * dbxread.c (read_struct_type): Expression gives Sun3 4.0.3
5414 compiler fits, simplify it.
5416 * gdb.texinfo (directory command): Doc new dir command.
5417 source.c (directory_command): "dir" now puts things on the front
5418 of the path, moves dups up front, and handles multiple names
5419 on the command line, inserting each one in order. It also
5420 blows away cached line and full_filename info.
5422 * stack.c (backtrace_command): Skip "more stack frames follow"
5425 * Change #ifndef HAVE_VPRINTF to #define MISSING_VPRINTF in
5426 xm-convex.h, xm-hp300bsd.h, xm-isi.h, xm-merlin.h, xm-news.h,
5427 xm-np1.h, xm-pn.h, xm-pyr.h, xm-symmetry.h, xm-umax.h, xm-vax.h.
5428 The only odd one was Gould NP1, which had defined vprintf to
5431 * Merge Ted Goldstein <tedg@Eng.sun.com>'s changes for epoch.
5432 printcmd.c (print_command_1): Pass 'inspect' flag down as a global
5433 variable, inspect_it.
5434 valprint.c (print_string, val_print): Use the global inspect_it
5435 to indicate whether to print in Epoch style or normal style.
5437 Mon Oct 1 23:55:26 1990 John Gilmore (gnu at cygint)
5439 * printcmd.c (call_command): add an alias for the "print" command
5440 which runs expressions and doesn't print the result if void.
5441 (print_command_1): implement it.
5443 * command.c: Remove #if 0'd code. Initialize all the fields
5444 in add_cmd (). Rename do_nothing_command to
5445 not_just_help_class_command, and make it externally visible.
5446 command.h: add user_commands to struct.
5447 * main.c (define_command): Don't overload c->function with a char
5448 string as well as a function pointer.
5450 * eval.c (evaluate_subexp): Reinstall tiemann changes to
5451 calling convention of value_struct_elt () that got dropped in
5454 * tm-sparc.h (FRAME_FIND_SAVED_REGS): move to sparc-xdep.c.
5455 sparc-tdep.c (sparc_frame_find_saved_regs): ditto.
5457 * tm-sparc.h (POP_FRAME): replace some constants with defines.
5459 * sparc-xdep.c (store_inferior_registers): defer stores to regs
5460 until a good time (e.g. when we are about to run the child),
5461 saving ptrace calls.
5462 * infrun.c (proceed): handle DO_DEFERRED_STORES.
5463 * tm-sparc.h: define DO_DEFERRED_STORES.
5465 * sparc-xdep.c (store_inferior_registers): when storing float
5466 registers, don't store stack regs too. When storing the SP,
5467 however, DO store the stack regs too. This fixes a bug in which
5468 the dummy frame is not recognized when a call_function finishes,
5469 because its frame pointer (in the stack regs) was never
5471 (read_inferior_registers): Mark WIM and TBR and FPS and CPS valid
5472 even though we don't know how to read them from an inferior.
5473 valops.c (call_function): Comment about storing SP.
5475 * infrun.c (save_inferior_status): Save away the original bpstat
5476 chain so it can be restored later. Install the copied version for
5477 use by whoever saved the status. It will be blow away by
5478 restore_inferior_status, and the original chain restored. This is
5479 important for people who have pointers into the original.
5481 * breakpoint.c, command.h, copying.awk, dbxread.c, defs.h,
5482 findvar.c, frame.h, obstack.h, obstack.c, inflow.c, value.h,
5483 main.c, printcmd.c, sparc-tdep.c, symtab.c, valprint.c: lint
5486 Fri Sep 28 20:32:46 1990 John Gilmore (gnu at cygnus.com)
5488 * Makefile.dist: Roll version to 3.91.8. Add bfd.h and bfdconfig.h
5489 temporarily to the makefile. Add am29k-opcode.h and WHATS.NEW.
5490 Add stuff.c and kdb-start.c to the OTHERS list for tar files.
5492 Fri Sep 28 19:12:12 1990 John Gilmore (gnu at cygint)
5494 * Merge Mike Tiemann's multiple inheritance changes from Sun.
5495 Store the baseclasses in a type struct starting from array element
5496 0 rather than from the unusual array element 1.
5498 dbxread.c: the above.
5499 (virtual_context): Add
5500 Read new debug information about which virtual function table
5501 a virtual function is from, and store it in fn_field.fcontext.
5503 symtab.h: Add fcontextt. Fix baseclass indices. Typo in
5504 TYPE_FN_FIELD_STATIC_P.
5506 symtab.c: the above.
5507 valops.c: the above. Handle pointer casts of object *'s.
5508 (search_struct_method): Add.
5509 (value_struct_elt): First arg is now a pointer to a value, and is
5512 valprint.c: the above.
5513 values.c (value_virtual_fn_field): Add type arg. Handle
5514 offsetting to the proper object when calling virtual fns.
5516 (baseclass_addr): Add valuep arg.
5518 * README: Document the current state of BFD config (missing).
5519 * TODO, ChangeLog, Makefile.dist: Roll version.
5520 * WHATS.NEW: Add summary of changes since 3.5.
5522 Thu Sep 27 16:23:12 1990 John Gilmore (gnu at cygint)
5524 * dbxread.c (read_struct_type): Clear bit vectors whenever
5526 symtab.c (B_CLRALL): define.
5528 * tm-sparc.h (STORE_RETURN_VALUE): Avoid clobbering types by
5529 using == rather than =. Huh... This fixes the dreaded problem
5530 wherein builtin_type_int becomes TYPE_CODE_FLT.
5532 * core.c (info_files): Show the inferior pid.
5534 * config.gdb: Avoid putting "dir" command into .gdbinit. GDB
5535 already knows how to look in the source directory.
5537 * Remove psymtab hair from many places. Remove duplicated code
5538 for searching symbol tables. Hide psymtabs from most places.
5539 Make it fast to get from a psymtab to its symtab.
5541 blockframe.c (blockvector_for_pc): Remove psymtab hair.
5542 coffread.c (psymtab_to_symtab): Rename to psymtab_to_symtab2.
5543 mipsread.c (psymtab_to_symtab): Rename to psymtab_to_symtab2.
5544 dbxread.c: export psymtab_to_symtab, make it work if called N times.
5545 (psymtab_to_symtab): Rename to psymtab_to_symtab2. Initialize
5546 new symtab completely. New psymtabs get symtab pointer
5547 initialized to zero. Remove MI warning printf.
5548 symtab.h: Comments. Add psymtab to symtab pointer.
5549 (PSYMTAB_TO_SYMTAB): New macro.
5550 symtab.c: use PSYMTAB_TO_SYMTAB. Add psymtab_to_symtab and export it.
5551 source.c: use PSYMTAB_TO_SYMTAB. Remove symtab version and
5553 stack.c (backtrace_command): Avoid pre-pass to read symbols, if
5555 (print_frame_info): Avoid special-casing symbols that have not yet
5558 * source.c (open_source_file): Quick path if we have already
5559 located the source file by its full name.
5561 * symtab.c (lookup_symbol): Use find_pc_symtab rather than
5562 find_pc_psymtab. When a name is found in the misc function
5563 vector, search the symbol table for its mangled name, not the
5564 name that the user typed.
5566 * bfd.h: Fix missing comment terminators, make #endifs match.
5568 * valarith.c (value_less): Handle unsigned int comparisons.
5569 Add FIXME about pointer compares, which assume host and target
5570 pointers are the same.
5572 * command.c (do_nothing_command): lint
5573 dbxread.c: lint. Remove sort_syms. Document C++ visibility info,
5574 fix comments on debug symbol format for visibility. Actually set
5575 visibility of symbols.
5576 main.c (echo_command): lint; use <readline/history.h>.
5577 tm-sparc.h (FRAME_FIND_SAVED_REGS): lint
5578 obstack.h (_obstack_blank): Rearrange pointer math to avoid
5579 pointing past end of allocated memory; saber complains.
5580 obstack.h: Declare the external functions that we use.
5581 valarith.h: use <string.h>
5582 solib.c (solib_add): lint.
5584 Fri Sep 21 17:05:19 1990 John Gilmore (gnu at cygint)
5586 * main.c (initialize_main): Default info_verbose to off, now that
5587 symbol reading is fast.
5588 (quit_command): Avoid clobbering exec_bfd while quitting.
5590 * Initial BFD (binary file diddling library) merger:
5591 coffread.c: Change AOUTHDR to struct exe_hdr.
5593 core.c: initialize initialized data at compile time.
5594 (core_file_command): Move from coredep.c, convert to bfd.
5595 (xfer_core_file): Convert to bfd.
5596 exec.c (exec_file_command): use bfd routines.
5598 mips-tdep.c: Remove exec_file_command and friends.
5601 * coredep.c: (fetch_core_registers) Convert core_file_command to
5602 fetch_core_registers.
5603 mips-xdep.c, sparc-xdep.c, sun3-xdep.c: ditto.
5605 * utils.c: (error): Bogus crap, FIXME, to print bfd errors.
5606 (my_bfd_read): More bogosity, which I don't think we call.
5607 (program_name): Remove this atrocity asap!
5609 Wed Sep 19 13:36:41 1990 John Gilmore (gnu at cygint)
5612 values.c: allocate_repeat_value was not clearing the
5613 optimized_out field.
5614 (value_static_field): minor stylistic fix (wrong macro was used).
5615 valops.c (value_struct_elt_for_address): didn't work for C++
5618 * signame.c (_initialize_signame): Initialize signal names once.
5620 * breakpoint.h, command.c, copying.awk, defs.h, environ.c,
5621 exec.c, frame.h, infcmd.c, inferior.h, main.c, munch, sun3-xdep.c,
5622 symtab.h, tm-29k.h, valprint.c, value.h, values.c: Lint.
5624 * remote-eb.c: Support user-settable baud rates on the serial port.
5626 * tm-sun3.h (PREPARE_TO_STORE): fix typo.
5628 Fri Sep 14 13:28:29 1990 John Gilmore (gnu at cygint)
5630 * tconfig/sun3os4: Remove warning about native assembler,
5631 since it also occurs in the xconfig file.
5633 * findvar.c (registers): Allocate some slop after `registers'
5634 to prevent stray accesses from trashing the next variable.
5636 * tm-68k.h (REGISTER_BYTES): Allocate the right number of bytes
5637 on the sun-3, by changing the #ifdef from `sun3' (which is not
5638 defined by cc) to `sun'. Symptom was trashed builtin_type_XXX
5639 vars, which happened to follow `registers' in the executable.
5641 * readline/history.c (history_search): Heed gcc-2's advice
5642 and parenthesize && inside ||).
5644 * am29k-opcode.h, am29k-pinsn.c, am29k-tdep.c, remote-eb.c,
5645 tm-29k.c: Insert FSF copyright headers.
5647 * remote-eb.c: Better comments.
5649 * Makefile.dist: Update to 3.91.6.
5650 * TODO: note PREPARE_TO_STORE problem.
5652 Thu Sep 13 09:52:33 1990 Jim Kingdon (kingdon at cygint)
5654 * stack.c (frame_info): Only use FRAME_FIND_SAVED_REGS if defined.
5656 * remote.c: Wrap the whole file in #if !defined (SPECIAL_REMOTE).
5658 * infrun.c (wait_for_inferior, at end): Don't set up
5659 prev_* if the inferior no longer exists.
5661 * inferior.h (CALL_DUMMY_LOCATION): New macro, to replace
5662 CANNOT_EXECUTE_STACK.
5663 valops.c (call_function): Use it.
5665 * tm-convex.h: Add CALL_DUMMY_LENGTH for use by PC_IN_CALL_DUMMY.
5667 * inferior.h (PC_IN_CALL_DUMMY): New macro.
5668 infrun.c (wait_for_inferior, 2 places): Use it.
5670 * values.c (value_being_returned): Only use
5671 EXTRACT_STRUCT_VALUE_ADDRESS if defined.
5673 * Move PREPARE_TO_STORE from xm-sun3.h to tm-sun3.h to do the
5674 right thing for remote-eb.c.
5676 * sun3-xdep.c: Remove extraneous call to remote_store_registers.
5677 * sun386-xdep.c, hp300hpux-xdep.c, sparc-xdep.c: Ditto.
5679 * blockframe.c: Put get_frame_saved_regs inside #if !defined
5680 (FRAME_FIND_SAVED_REGS).
5682 * findvar.c ({fetch,store}_registers): Check for
5683 REMOTE_{FETCH_STORE}_REGISTER macro.
5685 * findvar.c (get_saved_register): Add argument lval and
5686 change meaning of argument addr.
5687 findvar.c: Change calls to get_saved_register to reflect
5688 new calling convention.
5689 valops.c (value_assign): Use get_saved_register instead of
5690 find_saved_register.
5692 Sun Sep 2 12:40:20 1990 Jim Kingdon (kingdon at cygint.cygnus.com)
5694 * coffread.c (read_one_sym): Make temp_aux an AUXENT, not
5695 an (uninitialized) pointer to one. Use "&" when passing it
5698 Fri Aug 31 22:57:54 1990 Jim Kingdon (kingdon at cygint.cygnus.com)
5700 * coffread.c (getfilename): Use DGUX x_offset and x_name if
5703 * coffread.c (symbol_file_command): Put semicolon after
5705 Put safe_to_init_tdesc_context in #if defined (TDESC).
5706 Put #ifdef TDESCs in 1st column for non-ANSI cpp's.
5707 coffread.c: #include <sys/stat.h>.
5708 (read_coff_symtab): Typo: in_source_files -> in_source_file.
5709 Add missing ')' in check for "lc%" and friends. Remove
5711 Declare read_one_sym() at top of file.
5712 (read_file_hdr): Put in extra #ifdefs so MC68MAGIC and
5713 MC68WRMAGIC can have the same value without causing a duplicate
5716 Thu Sep 13 15:55:36 1990 John Gilmore (gnu at cygint)
5718 * Allow a Makefile to be built without building the
5719 tm and xm file links that screw up builds in subdirectories.
5720 This is done with `config.gdb none', then you can do things
5721 like `make gdb.tar.Z'.
5722 * tconfig/none: Config file for no target system
5723 * xconfig/none: Config file for no host system
5724 * config.gdb: If no TM or XM files are called out by the
5725 host or target file, don't make links for them.
5727 * cplus-dem.c: Add documentation.
5729 * dbxread.c (read_ofile_symtab): Turn a fatal error into a
5730 simple error, so the user's gdb doesn't crash due to some object
5731 file problem (e.g. somebody is rebuilding the file out from under
5734 * printcmd.c (print_address_symbolic): demangle the symbol.
5736 * Makefile.dist (OTHERS): Remove tdesc-lib because it has
5737 Motorola copyrights in it. Make "make gdb.tar.Z" work.
5738 (alldeps.mak): sort and uniq all results from this; duplicates
5739 hose gdb.tar.Z link building. Remove RCS files from
5740 tconfig and xconfig. Add config files for sun386. Add
5741 a few odd files to OTHERS and HFILES.
5743 Mon Sep 10 21:20:24 1990 John Gilmore (gnu at cygint)
5745 * Makefile.dist: Pull solib.c to tconfig/sun?os4.
5746 Roll version number to 3.91.5. Make lint work in bindir.
5748 * README: Document cross-debugging and new file structure.
5750 * blockframe.c: Lint. Include "value.h" to declare read_register.
5751 (find_pc_partial_function): remove duplicate line.
5753 * command.h: Lint. Declare error_no_arg and dont_repeat.
5755 * tm-news.h: Remove inadvertently duplicated stuff.
5757 * mipsread.c: Remove cache_pc_function stuff, now done cleanly.
5758 Clean up usage of misc_function_type. Declare some CORE_ADDRs.
5760 * config.gdb: Allow `config.gdb host target' form. Clean
5761 up previous change that printed bogus messages when you just said
5764 * core.c: #include "command.h" for lint.
5767 * main.c: Remove some casts of enums. Lint.
5774 * printcmd.c (initialize_printcmd): Fix thinko in inspect cmd.
5776 * sparc-tdep.c (isannulled): Take instruction as parameter, don't
5777 read it from memory. This will allow us to save ptrace calls
5778 eventually. Changed caller single_step too.
5780 * sparc-xdep.c (fetch_inferior_registers): Avoid reading regs
5781 that we aren't going to use, saving many ptrace calls, especially
5782 when watchpointing or single stepping. Use some #define's for
5784 (store_inferior_registers): Ditto.
5785 (core_file_command): Use some #define's for constants.
5787 * tm-sparc.h: Add #define's for some register numbers, so we
5788 can eliminate the use of random constants in sparc-xdep.c.
5790 * stack.c (frame_command, print_frame_info, up_command,
5791 down_command) Remove frame_changed, since it
5792 causes a bug and doesn't seem to do anything useful. In some
5793 places it was used as a flag, in others as a stack level (?).
5795 * utils.c: Use MISSING_VPRINTF rather than HAVE_VPRINTF, so the
5796 default is to use the portable (vprintf) version rather than the
5798 * xm-news.h (MISSING_VPRINTF): Add.
5800 * valprint.c (val_print): Demangle fancy vtbl printouts. Lint.
5802 Sat Sep 8 00:24:12 1990 John Gilmore (gnu at cygint)
5804 * Remove stuff that forces -Bstatic linking of gdb, and warnings
5805 about linking debugged programs -Bstatic in the sun?os4 config
5806 files in tconfig and xconfig subdirectories.
5808 * main.c (main): Remove unreached exit(0) now that we exit
5811 * Create TODO file for online bug list. There are too many
5812 "little" bugs to keep track of on paper.
5814 * Change Projects file to refer to bug-gdb@cygnus.com
5815 rather than kingdon@ai.
5817 Fri Sep 7 23:35:15 1990 John Gilmore (gnu at cygint)
5819 * Makefile.dist (VERSION): 3.91.4 now.
5821 * symtab.c (init_misc_bunches): Rename from init_misc_functions.
5822 (condense_misc_bunches): Add sanity check that misc_count is
5823 the same as the number of symbols in the bunch.
5825 * coffread.c: rename init_misc_bunches. Pass an argument
5826 to condense_misc_bunches (a zero).
5828 * dbxread.c (partial_symbol_file_read): Call init_misc_bunches
5829 every time we are called; don't rely on our caller to do it.
5830 (add_file): Remove call to init_misc_bunches.
5832 * mipsread.c: Only warn, don't error, if unknown symbol types.
5833 This keeps an old gdb from falling on its face if it sees newly
5834 extended symbol info. Rename init_misc_bunches.
5836 Fri Sep 7 22:58:15 1990 John Gilmore (gnu at cygint)
5838 * Merge in changes from Per Bothner for DECstations and other
5839 MIPS stuff. The rest is Bothner speaking:
5841 The next message is a merger of Alessando Forin's mips port with
5842 mine. I've tried to use my good if biased judgment to get
5843 the best of both. It *does* need testing.
5845 Some of the changes are general, *not* mips-specific.
5848 Didn't believe in little-endian bit order.
5849 There are still inconsistencies about whether flags
5850 like BITS_BIG_ENDIAN are integer (#if ...) or
5851 boolean (#ifdef ...). I tried to paper over them.
5853 dbxread.c,coffread.c,mipsread.c,symtab.c,symtab.h:
5854 Moved some misc_function code that was common to
5855 {dbx,coff,mips}read.c to symtab.c.
5856 In the process, I think I cleaned things up a bit.
5857 At the same time, moved obsavestring and obconcat to symtab.c.
5860 Removed obsolete condense_addl_misc_bunches (use
5861 condense_misc_bunches(1) instead).
5864 Needed to include <sys/dir>, at least on DECstations.
5866 valops.c, mips-tdep.c, tm-mips.h:
5867 Added PUSH_ARGUMENTS macro to support funny argument-pushing
5868 conventions (when STACK_ALIGN is insufficient).
5869 Needed on mips, where doubles need 8-byte alignment,
5870 but ints only need 4.
5873 Removed cruft that was not being used.
5874 Merged in many fixes (most from Frank Yellin, fy@lucid.com).
5877 Print $ before register-names (I think that makes things a little
5879 Never print two instructions, even if one delays.
5880 Removed hex-disassemble set_cmd. (This is not mips-specific,
5881 so I think the argument is whether it is generally worthwhile or not.
5882 I'm inclined to think not, given how easy it is to
5883 convert between radixes in gdb.)
5886 This is basically Alessando's code.
5887 It doesn't use obstacks; I changed it to use obstacks
5888 in a few minor places where using malloc causes a
5889 memory leak. (Probably, more places could/should be changed.)
5890 I added record_misc_function where it was missing.
5891 In symbol_file_command and add_file_command, I tried
5892 to make the code consistent with more recent versions.
5893 Minor sylistic changes in parse_procedure.
5894 Make a .gdbinfo. psuedo-symbol point back to the real
5895 procedure symbol (using the isym field).
5898 This is basically from my port, but with a lot of details
5899 and a number of routines merged in from Alessando's version.
5900 I basically used my code "raw" backtrace (use heuristics
5901 from the actual code, rather than symbol table info) - though
5902 the idea is Alessandro's. I feel my code is a little cleaner
5903 here, particularly in being a little more flexible, such as being
5904 able to handle gcc-produced code (which it now can).
5905 It also doesn't do frame caching (which is not useful
5906 more recent gdb versions).
5907 I also used my code for push_/pop_dummy, more or less.
5908 I tried to incorporate AF's code for testing sigtramp
5909 while backtracing; I probably got it wrong.
5910 Added mips_print_register, which tries to scrunch as much
5911 information as possible on a screen...
5912 Removed the skip-prologue set_cmd. As with hex-disassemble (see
5913 under mips-pinsn.c), I don't see anything mips-specific here,
5914 and I don't see it being all that useful anyway.
5917 Added a $fp psuedo-reg distinct from $fp (nice for gcc).
5918 Use more register names (rather than hard-cases numbers).
5920 Thu Sep 6 18:33:15 1990 John Gilmore (gnu at cygint)
5922 * Hack up 3.90.11 changes:
5924 * Makefile.dist (depend): parameterize $(GCC).
5925 Add solib.c and solib.o.
5926 (readline): Fix vpath for both absolute or relative SRCDIR.
5928 * blockframe.c: Fix from Schaefer@asc.slb.com for shared libs.
5929 Also, let the part I didn't understand at least compile so
5930 I can test the rest. FIXME.
5932 * dbxread.c: Fix thinko using strcmp.
5933 (init_psymbol_list): declare static.
5934 (partial_symbol_file_open): Comment cleanups better, avoid
5935 cleaning up the string table since the caller will do that.
5936 Move the stat for mod time into symbol_file_command, temporarily.
5937 (There should be a mod time for each symbol file, eventually,
5938 to control its rereading. FIXME.)
5940 * infptrace.c (PT_WRITE_D): use same value as PT_WRITE_I for
5941 SunOS, which gives error for shared libs otherwise. (From
5942 Schaefer, probably FIXME needs work for portability.)
5944 * solib.c: Move #include "param.h" to work.
5945 Lowercase all the Uppercase Letters In the Messages.
5946 (find_solib): Clean up inferior_so_name for debug printouts.
5947 Allow no argument, to mean all shared libraries.
5949 * symmisc.c: include param.h to get CLEAR_SOLIB.
5951 Wed Sep 5 18:00:08 1990 John Gilmore (gnu at cygint)
5953 * Merge in Kingdon's changes from FSF: the diffs from 3.90.9
5954 to 3.90.11. ChangeLog entries below are from this.
5956 Wed Jun 13 09:17:39 1990 Jim Kingdon (kingdon at mole.ai.mit.edu)
5960 * Makefile.dist (HFILES): Add tm-sunos.h.
5962 Tue Jun 12 16:15:26 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5966 * Makefile.dist (gdb.tar.Z): Change linking of config so it works.
5968 Thu Jun 7 16:22:27 EDT 1990 Jay Fenlason (hack@ai.mit.edu)
5970 * sparc-opcode.h Added single-operand version of rett.
5972 Mon Jun 4 18:12:31 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5974 * m-sparc.h (REG_STRUCT_HAS_ADDR, STRUCT_ARG_SYM_GARBAGE):
5975 Put parens around gcc_p in expansion.
5977 Thu May 24 15:44:51 1990 Jim Kingdon (kingdon at mole.ai.mit.edu)
5979 * utils.c (lines_to_list): Return 10 if lines_per_page == 0.
5981 Wed May 23 16:36:04 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5983 * Changes for Sun shared libraries:
5984 blockframe.c (find_pc_partial_function): If a non-text symbol
5985 is found, set *address = pc - FUNCTION_START_OFFSET.
5986 breakpoint.c (insert_breakpoints) [DISABLE_UNSETTABLE_BREAK]:
5987 Disable breakpoints instead of giving an error.
5988 source.c (select_source_symtab): Initialize cs_pst.
5989 symmisc.c: Call CLEAR_SOLIB if defined.
5990 symtab.h: Make text{low,high} CORE_ADDR not int.
5991 (psymtab): New field addr.
5993 dbxread.c: Move DECLARE_FILE_HEADERS outside functions.
5994 (record_misc_function): Give correct type for N_DATA symbols.
5995 (condense_misc_bunches): do "misc_function_count = j" regardless
5997 Take code which is shared between symbol_file_command and
5998 add_file_command and put it into partial_symbol_file_{open,read}.
5999 Split add_file_command into add_file_command and add_file.
6000 Make psymtab_to_symtab read in the string table if the file
6002 Two new parameters to read_dbx_symtab and start_psymtab.
6003 tm-sunos.h: New file.
6005 Tue May 22 17:43:03 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
6007 * infcmd.c: Change cont_command to continue_command and "cont"
6010 Mon May 21 14:41:41 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
6012 * breakpoint.c (enable_breakpoint): Get value of watchpoint.
6014 * defs.h [sparc]: Use <alloca.h> regardless of __GNUC__.
6016 * values.c (USE_STRUCT_CONVENTION): Check for structures of
6017 size 1,2,4,8 rather than size < 8.
6019 * dbxread.c (dbx_lookup_type): Do f->length *= 2 as many times
6020 as necessary, not just once.
6022 * sparc-opcode.h: Add a bunch of new opcodes which Sun as supports.
6024 Thu May 17 15:04:09 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
6026 * {t,x}m-sun386.h, sun386-xdep.c, {x,t}config/sun386
6028 * tm-news.h: Add CALL_DUMMY_*.
6030 * tm-68k.h: Remove duplicate comment at FRAME_FIND_SAVED_REGS.
6032 * config.gdb: In list_host, list_target, use ${i}, not $i.
6034 Tue May 15 21:27:12 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
6036 * source.c (find_source_lines) [BROKEN_LARGE_ALLOCA]: Use xmalloc.
6038 * sparc-opcode.h: Change all store floating-point state register
6039 instructions to have the right match & lose fields.
6041 Sat May 5 12:39:18 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
6043 * Makefile.dist: Move -I${srcdir} to GLOBAL_CFLAGS and pass
6045 config.gdb: If srcdir != ., create readline directory and
6046 copy a makefile into it.
6048 * wait.h, infrun.c: Change WRETCODE to WEXITSTATUS for
6049 consistency with POSIX.
6051 * breakpoint.c (bpstat_stop_status): Disable watchpoint
6052 when we exit its exp_valid_block.
6054 Tue Sep 4 11:46:46 1990 John Gilmore (gnu at cygint)
6056 * Makefile.dist: Bump version to 3.91.3.
6058 * Clean up handling of breakpoint commands (somewhat).
6059 Prompted by Tiemann bug report "cont 10" doesn't work any more.
6061 inferior.h: Add breakpoint_proceeded to inferior status struct
6062 and globals; save it and restore it.
6063 (clear_breakpoint_commands): Cleanup, remove old #define.
6065 infrun.c (clear_proceed_status): Set breakpoint_proceeded.
6066 (save_inferior_status, restore_inferior_status): handle it also.
6067 (proceed): Remove earlier code that set breakpoint_proceeded.
6068 It is now set only in clear_proceed_status.
6069 (clear_proceed_status): Cleanup, use bpstat_clear rather
6070 than clear_breakpoint_commands. No callers need the stop_bpstat
6071 between clear_proceed_status and proceed.
6073 infcmd.c: Add breakpoint_proceeded definition and comment.
6074 (cont_command, jump_command, signal_command): Move call to
6075 clear_proceed_status right next to call to proceed.
6077 breakpoint.c (bpstat_do_actions): Avoid clobbering our
6078 caller's argument while running down the chain of breakpoints.
6079 Use new variable "breakpoint_proceeded" to determine when
6080 a command that it executes moves the inferior past the
6082 (bpstat_clear): Handle NULL argument.
6083 (bpstat_clear_actions): Avoid useless call to
6084 breakpoint_auto_delete.
6085 (delete_breakpoint): Clean up bpstat's that are pointing to
6086 the deleted breakpoint from the stop_bpstat chain.
6087 (breakpoint_auto_delete): Simplify.
6089 * Clean up handling of EOF, error on stdin, etc. This was
6090 prompted by a network problem that caused gdb to go into an
6091 infinite loop filling up its malloc'd memory.
6093 main.c (return_to_top_level): Cleanup: call bpstat_clear_actions,
6094 not clear_breakpoints_commands, which is now gone.
6095 (main): If command_loop returns (e.g. from EOF on stdin), do
6096 a quit_command (looping back to command_loop if quit_command
6097 doesn't really quit).
6098 (command_loop): check result from command_line_input and
6099 exit if it returns NULL, rather than passing the NULL to
6101 (gdb_readline): Free malloc'd result space before returning
6104 * utils.c (query): Handle C-d to mean "yes", just as if the
6105 input was not a terminal. Also avoid infinite loop if EOF
6106 occurs in mid-input-line before newline. This allows
6107 query to be used at EOF on stdin with reasonable results.
6109 * infrun.c (proceed): Set breakpoint_proceeded.
6111 * values.c (value_as_long): Avoid infinite recursion for enums.
6112 (_initialize_values): Fix typo in help msg (kingdon).
6114 * Makefile.dist (RL_LIB): Use RL_LIB_DEP for dependencies,
6115 RL_LIB for linking. This allows -lreadline for linking
6116 and nothing for dependencies, once readline is a real library.
6118 * config.gdb: Jim Kingdon: give useful error message if the
6119 host or target type is not recognized.
6121 * defs.h (alloca): SPARC <alloca.h> does not declare alloca,
6122 it just defines it. Dumb, but deal with it.
6124 * Jim Kingdon suggests:
6125 in xconfig/sun3os4, CFLAGS should be XM_CFLAGS.
6127 Wed Aug 29 18:03:27 1990 John Gilmore (gnu at cygint)
6129 * Makefile.dist (VERSION): Bump version # to 3.91.2.
6131 * Clean up Bothner's changes.
6133 * blockframe.c (clear_pc_function_cache): New function.
6134 * blockframe.c: remake cache_pc_function_* static.
6135 * dbxread.c (symbol_file_command): remove references to
6136 cache_pc_function_* variables.
6137 * dbxread.c (read_struct_type): Use VOFFSET_STATIC.
6138 * printcmd.c: Avoid kludging a global variable (addressprint)
6139 to avoid printing the address of a string twice. Instead,
6140 pass the format letter 's' down low enough that it can be seen
6141 to avoid this problem.
6142 (print_formatted): Pass format arg to value_print.
6143 (restore_addressprint): Remove function.
6144 (do_examine): Avoid hacking addressprint, cleanups and such.
6145 (print_frame_args): Add a comment to a Bothner change.
6146 * symtab.h: define VOFFSET_STATIC and use it instead of "-1".
6147 * symmisc.c (free_all_symtabs): Call clear_pc_function_cache
6148 to wipe out the values cached in blockframe.c.
6149 * symtab.c (find_method): Add comment saying how big you must
6150 allocate to be "big enough". Per being terse again.
6151 * valprint.c (val_print): Handle format letter "s" to print
6152 strings without addresses. Add comment to vtbl printing code
6153 which casts with wild abandon. Rearrange reference-printing
6155 @0xaddr: value (print w/addressprint)
6156 value (print w/~addressprint)
6157 @0xaddr (parameter lists w/addressprint)
6158 or nothing (parameter lists w/o addressprint)
6160 Tue Aug 28 10:47:18 1990 John Gilmore (gnu at cygint)
6162 * Merge more changes from Per Bothner:
6164 Gdb's handling of TYPE_CODE_REF was so counter-C++ (and otherwise
6165 annoying) that I tried to improve it. Here are my suggestions.
6167 These patches all attempt to handle TYPE_CODE_REF (as in C++) better.
6170 Do automatic de-reference when taking the address of a reference.
6172 Don't deref_ref when printing parameter lists.
6174 More attempts at treating refernences properly.
6176 In val_print, if deref_ref==0, don't print dangling " = ".
6178 Add COERCE_REF macro, which de-references an REF.
6180 * Merge changes from Per Bothner:
6182 * Fixed (Sony news)-specific configuration problems.
6183 * Fixed other problems with using vanilla pcc and libc (enum problems;
6184 assumption that vsprintf exists).
6185 * Some major speed-ups (finc_pc_partial_function now caches a match;
6186 parsing avoids duplicate symbol_lookup calls).
6187 * Changed handling of baseclasses (no longer use baseclasses field
6188 of struct type, use the first n_baseclasses fields instead).
6189 * Various minor changes/fixes, most C++-related.
6192 Cache the most previous match from find_pc_partial_function.
6193 (Save both low and high ends of matching function's pc range.)
6194 This speeds up the loop of infrun.c:wait_for_inferior quite
6195 a bit, and makes step/next commands much zippier.
6197 Added an enum->int cast (otherwise, some compilers barf).
6199 No longer set baseclass offset to 0, since multiple
6200 inheritance now mostly works.
6201 Added a number of casts, to shut up compiler warnings
6202 (after stabs where made enums, not ints).
6203 When discarding a symbol table (in symbol_file_command),
6204 must clear the cache introduced in blockframe.c.
6205 Don't convert $vtbl_ptr_type to vtbl any more.
6206 Get rid of TYPE_BASECLASEES and baseclass_vec (see also symtab.h).
6207 Mask off sign bit emitted by g++ for virtual table offset.
6208 Set voffset to -1 (not 1) for static member functions.
6210 Changed parsing/lexing of names to avoid doing symbol lookup twice
6211 (once when lexing to determine symbol class, once for real).
6212 Now only call symbol_lookup once. Fields of 'this' win especially big.
6214 Subpress printing addr twice in the case of 'x/s addr'.
6216 lookup_basetype_type is no longer used.
6217 Add find_methods as recursive helper function to decode_line_1.
6218 This allows multiple inheritance to work.
6219 Also, once one or more matches has been found, do not look in
6220 base-classes. (Baseclass methods would be overridden, anyway.)
6222 Removed baseclasses array in struct type.
6223 Instead of using baseclasses[i], use fields[i-1].
6224 Added virtual_field_bits[i] to indicate if the i'th baseclass is virtual.
6225 Changed sign convention of voffset (previous was inconsistent).
6227 Some macros (CALL_DUMMY and relatives) were missing. Put them back.
6229 Used to assume existence of vsprintf. Re-written to not need it
6230 if HAVE_VPRINTF is undefined.
6232 typecmp was too pessimistic. Made it less so.
6234 Don't print space after address.
6235 If vtable points to a misc symbol (with 0 offset), print it,
6236 since that indicates the actual class of the object.
6237 Changed ype_print_derivation_info to use new inheritance
6238 scheme (without baseclasses vector).
6240 In value_primitive_field, fixed some bugs left over from previous set of fixes.
6241 Also, changes needed because TYPE_BASECLASSES were removed.
6243 REGISTER_U_ADDR didn't work for PC. Rewrote to use an array.
6245 Tue Aug 21 20:08:54 1990 John Gilmore (gnu at cygint)
6248 If there is no path set, and the symbols don't indicate what directory
6249 a file was compiled in, look in the current directory. But either
6250 a path or a known compilation directory will prevent this.
6253 Three independent bug fixes:
6254 * Remove the #if 0 block that breaks some stuff.
6255 * SunOS 4.1 fixed the promoted-parameter-wrong-addr bug in Sun C;
6256 adapt gdb to either SunOS 4.0.* or 4.1.
6257 * MAX_OF_TYPE and MIN_OF_TYPE thinko. By tedg@sun, I think.
6260 Instantiate the class T when looking for methods in it. (Tiemann@sun)
6263 (type_print) Demangle the name being printed.
6264 (type_print_base) Handle botched demangling without coredump (tiemann).
6267 (check_stub_method): Document routine.
6268 (tiemann) fix bug for no-arg functions
6269 Avoid clobbering beyond end of malloc'd storage.
6270 Terminate the argument list properly.
6272 Sat Aug 18 01:29:59 1990 Per Bothner (bothner@cs.wisc.edu)
6274 * Changes merged by John Gilmore:
6277 In breakpoint_1, use new print_address_symbolic instead
6278 of find_pc_partial_function. (This forces use of assembler-level
6279 addresses, and avoids misleading non-mangled source-level names.)
6281 Generalize ansi argument such that -1 means skip arglist totally.
6282 Removed global variable print_ansi_qualifiers (which made
6283 code non-reentrant), in favor of extra explicit arguments
6284 to internal routines.
6286 Add new helper function print_address_symbolic.
6287 Use find_pc_misc_function instead of find_pc_partial_function
6288 (since we want assembler-level symbols here).
6290 Print unknown function as just "f (...)", not "f (...) (...)".
6291 Use new fputs_demangled explicitly.
6293 Fixed a typing violation (problem: value.h cannot be imported
6294 without renaming many variable in this file).
6295 lookup_symbol: If no matching misc_func, look for a C++-mangled name.
6296 decode_line_1: Moved forward some never-reached code.
6297 Made decode_line_2 skip function prologues correctly.
6299 fputs_filtered should not demangle by default.
6300 Add new fputs_demangled to demangle on demand..
6302 Change value_struct_elt to use value_primitive_field (using recursive
6303 utility function search_struct_field). This allows foo.bar to work
6304 for multiple inheritance (so far only for data fields).
6305 Change check_field in the same way (recursive helper function
6306 to support multiple inheritance).
6307 (Note: there are more of these problems that I haven't fixed.
6308 Any code that says TYPE_BASECLASS (t, 1) is probably wrong.)
6309 value_of_this: 'this' symbol name is now just "this", note "$this".
6311 Don't print static members.
6312 Avoid printing "members of <type>" if there are none.
6313 Simplified type_print_derivation_info by merging duplicate code.
6314 Remove useless blank lines in type_print_base (ptype command).
6316 Added declaration of new routine value_primitive_field.
6318 Added value_primitive_field which is generalized version of
6319 value_field that can handle multiple inheritance (non-zero offsets etc).
6320 Re-implemented value_field to call value_primitive_field.
6322 Fri Aug 17 23:33:44 1990 John Gilmore (gnu at cygint)
6324 * infcmd.c -- insert else to avoid 'delete env' coredump when you
6325 delete the whole environment. Karl Berry reported the bug.
6326 * source.c - fix openp to avoid //'s in filenames, which
6327 trigger an Emacs bug causing it to not be able to find files
6328 when running gdb in a window.
6329 * dbxread.c - zap the #if 0 that botches the add-file code.
6330 It seems to work a lot better without all the code commented out.
6332 Fri Jul 20 16:58:46 1990 John Gilmore (gnu at cygnus.com)
6334 * Merge Tiemann's and Ted Goldstein's changes, detailed below,
6337 Tue Jul 17 19:34:33 1990 Ted Goldstein (tedg at golem)
6339 * Makefile - added a ${CFLAGS} to a couple of entries,
6340 added remote-sa.sparc.c
6341 * added remote.sa-sparc.c, a modification of remote.c
6342 which conducts a dialog directly with the SparcStation prom.
6343 * breakpoint.c, infrun.c, sparcdep.c added
6344 remote_insert_breakpoint(), and remote_remove_breakpoint()
6345 to breakpoint.c instead of directly writing breakpoint instructions.
6346 * sparcdep.c on remote_debugging,there is no need
6347 to remove signle step breakpoint instructions.
6348 * main.c added "-epoch" flag and "int epoch_interface" to main.c
6350 * printcmd.c - epoch interface sends lisp expressions to open up
6351 epoch windows on inspection.
6352 * valprint.c - added arrayprint, and addressprint and made adding
6353 format controls easier
6354 * wait.h added a couple of undef's because we were getting
6355 complaints about WSTOPSIG and WTERMSIG begin redefined.
6358 Wed Jul 4 05:27:51 1990 Michael Tiemann (tiemann at masham)
6360 * symtab.c (decode_line_1): Add support for handling method stubs
6361 in the type information.
6363 Tue Jul 3 09:39:18 1990 Michael Tiemann (tiemann at masham)
6365 * values.c (baseclass_addr): Run loop from INDEX+1 to
6366 N_BASECLASSES; otherwise, we can still get into a loop.
6367 @@ This should be restructured to use a cleaner search strategy.
6369 Sun Jul 1 12:28:51 1990 Michael Tiemann (tiemann at masham)
6371 * dbxread.c (define_symbol,read_type): Grok GNU C++'s new
6372 abbreviation "Tt" for tags which have the same name as their
6375 Fri Jun 29 01:03:46 1990 Michael Tiemann (tiemann at masham)
6377 * symtab.c (list_symbols): add ability to set breakpoints on all
6378 the functions which match a particular regular expression.
6380 Tue Jun 26 04:26:29 1990 Michael Tiemann (tiemann at masham)
6382 * cplus-dem.c (cplus_demangle): New parameter ANSI says whether we
6383 should print ANSI qualifiers (such as `const' and `volatile').
6384 All callers changed to call with ANSI == 1, except from
6385 `check_method_stub', which uses old-style syntax.
6387 * symseg.h (struct fn_field): Remove unneccessary `args' field.
6388 * symtab.h (TYPE_FN_FIELD_ARGS): Redefined.
6390 * values.c (check_stub_method): New function.
