1 Fri Nov 22 16:39:57 1991 John Gilmore (gnu at cygnus.com)
3 * tm-tahoe.h (FRAME_ARGS_ADDRESS): No need to offset from frame
6 * m2-exp.y (MAX, MIN): Rename to MAX_FUNC, MIN_FUNC to avoid
7 conflicts with system header files.
9 Fri Nov 22 08:27:40 1991 John Gilmore (gnu at cygnus.com)
11 * Roll VERSION to 4.2.95.
13 * buildsym.c, coredep.c, mem-break.c, xcoffread.c: Put <stdio.h>
15 * config/mh-i386sco: Override compiler to gcc, print warning.
16 * configure.in: Handle i386-none-aout rather than i386-aout-none.
17 * infptrace.c, language.h, utils.c: Lint.
18 * m2-exp.y: #undef MAX and MIN in case system includes set them.
19 * xm-tahoe.h: Set HOST_BYTE_ORDER. Include system versions of
20 {BIG,LITTLE}_ENDIAN and the INT_MAX family first, to avoid
21 redefinition warnings.
22 * defs.h: Reorder things so that the xm-file gets first crack
23 at #define's, followed by defs.h and then the tm-file.
24 * Makefile.in: Remove spaces after 'ignore exit code' - flags.
25 Late-model BSD 'make's don't cope with them.
27 Thu Nov 21 23:48:56 1991 John Gilmore (gnu at cygnus.com)
29 * Makefile.in: Roll new files into various lists.
31 Thu Nov 21 18:26:11 1991 Fred Fish (fnf at cygnus.com)
33 * dwarfread.c (struct_type): Must initialize the c++ specific
34 portion of union types as well as struct types, since gdb attempts
35 to reference the c++ specific info for both types.
37 Thu Nov 21 10:23:52 1991 John Gilmore (gnu at cygnus.com)
39 * Makefile.in: Roll VERSION to 4.2.90.

42 * param-no-tm.h: Change users to define TM_FILE_OVERRIDE instead.
43 * param.h, param-no-tm.h: Removed.
44 * Update copyrights in all changed files.
45 * dbxread.c, dwarfread.c, inflow.c, infrun.c, m2-exp.y, putenv.c,
46 solib.c, symtab.h, tm-umax.h, valprint.c: Lint.
47 * tm-convex.h, tm-hp300hpux.h, tm-merlin.h, tm-sparc.h,
48 xm-merlin.h: Avoid host include files in target descriptions.
49 * getpagesize.h: Removed, libiberty copes now.
50 * Makefile.in: Remove getpagesize.h, param.h, param-no-tm.h.
52 * exec.c (exec_files_info): If `verbose' is set, show file offset

56 * standalone.c: Fake getcwd rather than getwd.
57 * xm-*.h: Remove fake values of MAXPATHLEN.
59 * xcoffexec.c: Add /* */ to #if 0'd thing to help ANSI.
61 Wed Nov 20 18:35:56 1991 John Gilmore (gnu at cygnus.com)
63 * Remove gdb/hp-include. Support for HP a.out oddities should be
64 in BFD, not in GDB. Move gdb/hp-include/a.out.h to include/a.out.hp.h.
66 * infptrace.c, tm-sun386.h: Cashier <a.out.gnu.h>, remove refs.
68 * configure.in, xconfig, tconfig, Makefile.in, doc/gdbint.texinfo:
69 Makefile fragments for various hosts and targets now come from
70 gdb/config/mh-* and gdb/config/mt-*. This is for consistency with
73 * rs6000-pinsn.c, rs6k-opcode.h: Clean up.
74 * rs6k-opcode.def: Delete.
76 Wed Nov 20 05:04:40 1991 Fred Fish (fnf at cygnus.com)
78 * dwarfread.c: Recognize obsolete form of AT_element_list
79 attribute still used by at least one AT&T compiler, and possibly
82 Tue Nov 19 07:53:55 1991 Fred Fish (fnf at cygnus.com)
84 * dwarfread.c (enum_type, struct_type): Ignore names invented by
85 helpful compilers for anonymous structs, unions, and enums.
87 * c-exp.y, m2-exp.y: Add defines for yymaxdepth, yy_yys, and
88 yy_yyv, so multiple parsers produced by SVR4 versions of yacc
89 can coexist in the same executable without collision.
91 * symtab.h: Add declaration for lookup_template_type() to kill
92 compiler warnings about conversions from int to pointer.
94 Mon Nov 18 17:45:18 1991 Fred Fish (fnf at cygnus.com)
96 * procfs.c: Move inclusion of defs.h to before param.h, as in
97 all the other source files that include both. This is required
98 to supply some typedefs that are used in files included by param.h.
100 * m68k-tdep.c (m68k_skip_prologue): Add generic m68k support for
101 skipping function prologues, ala the other cpu families (i386,
102 mips, m88k, etc). Add the ability to skip movm and fmovm
103 instructions in the prologues. Still needs support for profile
104 (-p compiled) prologue sequences (FIXME).
106 * tm-68k.h: Change SKIP_PROLOGUE macro to use the new generic
107 m68k prologue skipping function by default.
109 * tm-altos.h, tm-isi.h: Continue to use the old definition of
112 Mon Nov 18 15:12:45 1991 John Gilmore (gnu at cygnus.com)
114 * Makefile.in: Remove tdesc stuff, and extra blanks before colons.
115 * blockframe.c: Remove tdesc-related code. Default
117 * infrun.c: Remove tdesc-related code.
118 * m88k-tdep.c (frame_chain_combine, init_frame_pc): Remove copies
119 of defaultable things.
120 * tm-m88k.h: New file, common to all Moto 88k target configs.
121 Derived from tm-delta88.h.
122 * tm-delta88.h: Use it.
123 * xm-m88k.h: Common file for 88K hosts. Remove obsolete stuff.
124 * xm-delta88.h: Use it.
125 * tm-*.h: Remove FRAME_CHAIN_COMBINE macros, since all are
127 * coffread.c: Remove tdesc stuff.
128 * tconfig/delta88, tconfig/m88k: Remove tdesc stuff.
129 * xconfig/m88k: Rename tm-88k.h to tm-m88k.h.
131 Mon Nov 18 13:51:37 1991 Per Bothner (bothner at cygnus.com)
133 * source.c (open_source_file): If openp fails, try again
134 using just the base (non-directory) part of the filename.
135 This solves various annoying problems, such as when the
136 source was compiled with an absolute pathname - and the
137 source files have moved. Or if the source was compiled
138 using a relative pathname, it can be more convenient
139 to just specific the source directory to the dir command.
141 Mon Nov 18 00:04:41 1991 Fred Fish (fnf at cygnus.com)
143 * cplus-dem.c (munge_function_name): Add missing third arg to
144 instance of call to do_type().
146 * dwarfread.c: Changes to match new dwarf.h. Remove
147 AT_deriv_list, AT_loclist, AT_incomplete, AT_const_data,
150 Sun Nov 17 16:20:53 1991 Michael Tiemann (tiemann at rtl.cygnus.com)
152 * symtab.h (struct type): Moved C++-specific fields into new type
153 `struct cplus_struct_type'. Now takes 10% less memory. Many
155 * symtab.c (init_type): Don't set fields belonging to
156 TYPE_CPLUS_SPECIFIC unless TYPE is TYPE_CODE_STRUCT.
157 * buildsym.c (read_type): Allocate TYPE_CPLUS_SPECIFIC for
159 (read_struct_type): Ditto. Also, add comments about how we can
160 deduce TYPE_VPTR_FIELDNO from inheritance info and fieldname info.
161 * coffread.c (decode_base_type): Allocate TYPE_CPLUS_SPECIFIC for
163 (read_struct_type): Ditto.
164 * dwarfread.c (struct_type): Ditto.
166 * symtab.c (read_range_type): Don't set TYPE_MAIN_VARIANT.
167 (lookup_pointer_type): Don't use or set TYPE_MAIN_VARIANT.
168 (lookup_reference_type): Ditto.

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

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

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

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

294 * rs6000-pinsn.c, rs6000-tdep.c, rs6000-xdep.c, tm-rs6000.h,
295 xm-rs6000.h, rs6k-opcode.def, rs6k-opcode.h: New files.
296 * xcoffexec.c: New file for handling AIX shared libraries.
298 Mon Nov 11 19:14:31 1991 Fred Fish (fnf at cygnus.com)

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

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

386 (struct symtab): Add objfile * and objfile_chain * of symtabs.
387 (struct partial_symtab): Add objfile * and objfile_chain * of
388 psymtabs. Remove symfile_name.
390 * symmisc.c: Lose free_all_symtabs, free_all_psymtabs.

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

397 * symfile.h, symfile.c, symtab.h: Lint
399 Fri Nov 8 23:38:48 1991 John Gilmore (gnu at cygnus.com)
401 * command.c: Include param.h.
402 * defs.h (warning_setup, warning): Declare.

408 Thu Nov 7 18:26:15 1991 Steve Chamberlain (sac at rtl.cygnus.com)
410 * Makefile.in: link with libiberty after libreadline, since
411 readline might want something in libiberty.
412 * m88k-xdep.c: Fixed the register offsets in the ptrace_user
413 struct for BCS 88k machines.
414 * xm-m88k.h: don't define USIZE if already defined.
415 * configure.in: Added delta88 target.
417 Thu Nov 7 04:51:19 1991 John Gilmore (gnu at cygnus.com)
419 * am29k-pinsn.c, am29k-opcode.h: Fix decoding of mtacc, dmac, fmac.
421 * tm-*.h: Remove READ_DBX_FORMAT, COFF_FORMAT, and
422 READ_MIPS_FORMAT, which have been unused since BFD. Still
423 remaining is COFF_NO_LONG_FILE_NAMES.
424 * tm-sun3.h, tm-altos.h: Remove detritus accidentally left from
425 function calling code moved to m68k-tdep.c.
427 Wed Nov 6 17:21:59 1991 John Gilmore (gnu at cygnus.com)
429 * coffread.c: Eliminate c_nsyms in favor of c_naux.
430 Complain if no auxents on .bf and .ef FCN symbols, and assume
431 lots of line numbers.
432 (init_linenos, enter_linenos): Use a sentinel at the end of the
433 read-in linenos, to make for a fast, safe loop-end test.
435 Wed Nov 6 02:54:08 1991 Steve Chamberlain (sac at cygnus.com)
437 * coffread.c (read_coff_symtab): coffread used to rely on the
438 x_sym.x_misc.x_lnsz.x_lnno field giving the # of linnos in a
439 function. Two of the formats I'm using (29k and 88k) don't seem to
440 set it. Ths patch to fcn_last_line and (enter_linenos) is an
441 attempt to use the actual size of the linno table in the file to set
442 the number of linenos to process.
444 Tue Nov 5 22:47:46 1991 Steve Chamberlain (sac at cygnus.com)
446 * Makefile.in: put a - infront of the mv y.tab.c c-exp.tab.c and
447 mv y.tab.c m2-exp.tab.c, so that if bison is used, and the files
448 are created in place, so the mv fails, then the make continues.
450 Tue Nov 5 16:47:47 1991 Per Bothner (bothner at cygnus.com)
452 Add C++ as a separate language.
453 * defs.h (enum language): Add language_cplus.

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

968 * Makefile.in: Roll VERSION to 4.1.1.
969 * source.c (line_info): Peter Schauer fixes a bug I introduced in
972 Fri Sep 20 16:10:52 1991 John Gilmore (gnu at cygnus.com)
976 * Makefile.in (VERSION): Set to 4.1.
977 * language.c (set_language_command): Print useful help message,
978 and restore the language string after giving help.
979 * valprint.c (typedef_print): Print typedef in C or M2.
980 * symtab.c (list_symbols): Use it.
981 * main.c (main): Avoid any output before (gdb) prompt when -q.
982 * language.c (set_language_command): Handle errors by restoring
983 the language string to its current state (fix from A. Beers).
984 * doc/gdbint.texinfo: Roll in information from README. Rearrange
985 "how to install" and "how to print the doc" stuff so it drops
987 * configure.in: Rename rtpc CPU to romp to match config.sub.
988 * README, WHATS.NEW, TODO: Update for gdb-4.1.
990 Fri Sep 20 17:39:14 1991 Roland H. Pesch (pesch at cygnus.com)
992 * doc/gdb.texinfo: Updates from ChangeLog. set/show write,
993 autoloading shared libs, copyright etc on GDB startup, clean up $_
994 and $__ index refs, set/show listsize and related updates to list
995 cmd. New host/target configs.
997 Fri Sep 20 15:46:00 1991 Roland H. Pesch (pesch at cygnus.com)
999 * doc/Makefile: generate aux version-no file doc/gdbVN.m4
1000 from main Makefile.in version definition
1001 doc/gdb.texinfo: use version recorded in doc/gdbVN.m4 for current
1003 Makefile.in (setup-to-dist): generate doc/gdbVN.m4
1005 * doc/gdb.texinfo: merge new language-switching and lang-specific
1008 Fri Sep 20 15:00:57 1991 Per Bothner (bothner at cygnus.com)
1010 * mcheck.c: Add __ONEFILE kludge to allow compilation by non-ANSI
1011 compilers (which may lack stddef.h).
1013 Fri Sep 20 13:29:42 1991 John Gilmore (gnu at cygnus.com)
1015 * dbxread.c (read_dbx_symtab, process_one_symbol): N_FN and
1016 N_WARNING are the same except for the N_EXT bit, so just use their
1017 values alone, rather than OR-ing them with N_EXT.
1019 Fri Sep 20 12:27:55 1991 Stu Grossman (grossman at cygnus.com)
1021 * mipsread.c (parse_lines): Deal with negative extended line
1024 * c-exp.y, m2-exp.y: #define yyerrflag and yynerrs to avoid
1025 global symbol conflicts.
1027 Fri Sep 20 02:28:15 1991 John Gilmore (gnu at cygnus.com)
1029 * .gdbinit: Move 'set complaints' to top, so it runs even in
1030 case we aren't debugging GDB.
1031 * language.c (_initialize_language): Fix type check and range
1032 check documentation strings.
1033 * utils.c (!HAVE_VPRINTF): Define vfprintf as a function, so
1034 language.c can use it. (Though language.c should really not be
1035 handling warnings/errors the way it does, FIXME.)
1036 * symtab.c (lookup_primitive_type): const lint.
1038 Bugfix from Peter Schauer:
1039 * source.c (lines_to_list): Make signed, to avoid comparison
1040 going unsigned and complaining that -3 is too high for 21 lines.
1041 * stack.c (lines_to_list): Ditto.
1043 Thu Sep 19 23:33:41 1991 John Gilmore (gnu at cygnus.com)
1045 * Makefile.in (HFILES): Add minimon.h.
1046 (VERSION): Roll version number to 4.0.95.
1047 (gdb.tar.Z, make-proto-gdb.dir, setup-to-dist, gdb-XXX.tar.Z):
1048 New rules for building distributions. Normal distribution
1049 is built by doing `make -f Makefile.in gdb.tar.Z' in the directory
1050 one level up from here; it calls make-proto-gdb.dir to build a
1051 directory `proto-gdb' which is an image of the release. The old
1052 `gdb.tar.Z' rule still works too.
1053 * config.sub, configure: Roll in latest from ..
1055 Thu Sep 19 17:41:24 1991 Roland H. Pesch (pesch at cygnus.com)
1057 * doc/gdbint.texinfo: Reorder contents; reorganize new-host,
1058 new-target, and new-config chapters; fix minor typos; come closer
1059 to usual GNU markup conventions for @file @samp @code @var.
1061 Thu Sep 19 17:04:12 1991 Per Bothner (bothner at cygnus.com)
1063 Patches from Peter Schauer <pes@regent.e-technik.tu-muenchen.de>:
1064 * mipsread.c (parse_partial_symbols): Enter the name of all
1065 structs/unions... into the psymtab so we can access them if the
1066 symtab is not read in.
1067 * mips-tdep.c: Remove some unneeded #includes.
1068 * xconfig/dec3100: Add HAVE_STRSTR.
1070 Thu Sep 19 15:14:23 1991 John Gilmore (gnu at cygnus.com)
1072 * Makefile.in: Circumvent Sun Make bug on *-exp.tab.o.
1073 * c-exp.y, m2-exp.y: Lint.
1074 * m2-exp.y: Avoid using yytname[] which is a Bison-ism.
1075 * valprint.c (val_print_fields): Check for stub type.
1076 * mipsread.c (_initialize_mipsread): Avoid using
1077 builtin_type_void at initialize time.
1078 (mipscoff_symfile_read): use it now.
1080 Wed Sep 18 15:55:51 1991 John Gilmore (gnu at cygnus.com)
1082 Merge multiple-language support, and partial Modula-2 support,
1083 from Andrew Beers <beers@cs.buffalo.edu>.
1085 * i387-tdep.c: New file, consolidates most 80387 support,
1086 and eliminates host dependency on double<->extended conversions.
1087 * i386-xdep.c, symm-xdep.c: Remove most 387 support.
1088 * xconfig/i386{sco,v,v-g,v32,v32-g}: Now need i387-tdep.o.
1090 * symfile.c (allocate_symtab): New fn, consolidates the work
1091 of allocating and initializing a new struct symtab. Set the
1092 language of the symtab based on its filename extension.
1093 * symfile.h: Declare it.
1094 * mipsread.c (new_symtab): Use it. Minor formatting changes.
1095 * dbxread.c (end_symtab): Use it.
1097 * mipsread.c (parse_symbol, case stParam and stProc): Add #if 0'd

1104 * coffread.c (end_symtab): Use allocate_symtab.
1105 (process_coff_symbol): #if 0'd for functions and params as above.
1106 (read_enum_type): Recognize Modula-2 BOOLEAN.
1107 * symtab.c (add_param_to_type): #if 0'd function to add a

1114 hex with local_hex_string for Modula-2 support.
1116 * breakpoint.c (breakpoint_cond_eval): Use new value_true to test

1143 TYPE_CODE_BOOL and TYPE_CODE_CHAR.
1145 * expression.h (enum exp_opcode): Add Modula-2 specific opcodes.
1146 * expprint.c: Look up expression opcodes in language-specific

1179 Tue Sep 17 08:37:41 1991 John Gilmore (gnu at cygint.cygnus.com)
1181 Add Andrew Beers' changes for Modula-2 support. His ChangeLog
1182 entries are enclosed herein. Not all of these changes
1183 have been merged into the master GDB sources -- check the
1184 ChangeLog above here for the merge log.
1186 Mon Jun 3 17:05:45 EDT 1991
1188 m2-exp.y Created. Tested outside of GDB for a few days. Proper
1189 operators were added, C specific operators and tokens
1190 removed. yylex() revamped to some extent. Still things
1191 missing from the grammar, such as sets.
1192 Tested for two weeks in GDB v3.5.
1194 Tue Jun 11 17:23:48 EDT 1991
1196 m2-exp.y Added boolean constants TRUE and FALSE to the grammar
1197 so they are built-in. Sort of a hack.
1199 Fri Jun 14 12:53:51 EDT 1991
1201 m2-exp.y Added range checking for numeric constants. Any numeric
1202 constant is assumed to be of builtin type INTEGER unless:
1203 (1) it is octal or hexadecimal, in which case it is a
1204 CARDINAL; (2) it is too big to fit into an INTEGER, in
1205 which case it is a CARDINAL.
1206 eval.c Added simple range checking for +, -, and * on integers.
1207 Doesn't work very well for *, since 6 * 1,000,000,000 =
1208 1,705,032,704, which fails the simple test of result >=
1209 first_operand, no matter in what order the operands are.
1211 Tue Jun 18 14:11:30 EDT 1991
1213 Broke the parser into parts, one containing the C grammar and the other
1214 containing code to be shared by all of the grammars.
1216 The following files no longer exist:
1221 The following files were added:
1223 c-exp.y (The C grammar)
1224 m2-exp.y (The Modula-2 grammar)
1225 parser-code.c (Code that is shared by the above grammar)
1229 Makefile.dist Changed to reflect the above dependencies. NOTE: It is
1230 now necessary to use the Bison compiler compiler, since it
1231 will generate function/variable prefixes other than yy.
1233 Tue Jun 18 16:47:49 EDT 1991
1235 symtab.[ch] Added the external variable working_lang, than holds the
1236 value of the current working language.
1237 Added the ennumerated type language_mode, with the values
1238 language_auto and language_manual, the former meaning that
1239 GDB sets working_lang as needed, and the latter meaning
1240 that the value of working_lang is totally under user
1242 symtab.[ch] Added the Modula-2 pervasive types INTEGER, CARDINAL,
1243 REAL, BOOLEAN and CHAR. Also added the type codes
1244 TYPE_CODE_BOOL and TYPE_CODE_CHAR.
1245 utils.c Added set_language_command and show_language_command to
1246 implement the GDB support commands "set language" and
1248 expression.h A number of identifiers were added to the type exp_opcode
1249 to facilitate Modula-2 builtin functions, integer
1250 division, and array indexing.
1252 Wed Jun 19 13:25:58 EDT 1991
1254 language.h Added the macro STRICT_TYPE, which evaluates to non-zero
1255 if the language specified by working_lang requires the use
1256 of strict typing of expressions. Eventually, even this
1257 will be able to be changed by the user.
1258 Added the macro RANGE_CHECK, which evaluates to non-zero
1259 if the language specified by working_lang requires the
1260 checking of a value against the domain of its type.
1261 Eventually, even this will be able to be changed by the
1263 language.[ch] Predicates involving types (simple_type, ordered_type,
1264 same_type, integral_type, numeric_type, character_type,
1265 boolean_type, float_type) are added. These predicates are
1266 based on the current value of working_lang, and are handy
1269 Wed Jun 19 15:39:34 EDT 1991
1271 eval.c Added the function type_array_rank which computes the rank
1273 valarith.c Added the funtion value_bool, which when given a integer
1274 value.h value (ie. struct value *) as an argument, it returns a
1275 boolean value (ie. struct value *) true if that integer
1276 is non-zero, and a boolean value false otherwise.
1277 valprint.c Added cases for TYPE_CODE_BOOL, so Modula-2 BOOLEAN values
1278 will print out properly.
1280 Wed Jun 19 16:36:34 EDT 1991
1282 valops.c Added the function value_capitalize, which returns it
1283 value.h argument capitalized if its argument is a lowercase
1284 letter, or the argument unchanged if its argument is not a
1286 valarith.c Added the function range_check_p, which returns non-zero
1287 value.h if its value argument is between the integral bounds upper
1289 Added the function range_check_enum_p, which makes sure
1290 that its value argument is a valid member of the domain of
1292 Added the function range_check_range_p, which makes sure
1293 its value argument lies between the upper and lower bounds
1294 of its type argument, which must be a ranged type.
1295 Added the function check_array_index, which range and type
1296 checks an index of an array.
1297 Added the function value_multi_subscript, which computes
1298 array[idx1,idx2...idxN], given a value array and an array
1299 of values representing indicies.
1300 values.c Changed value_from_long to work with TYPE_CODE_CHAR and
1301 unpack_long to work with TYPE_CODE_BOOL and
1304 Wed Jun 19 18:04:08 EDT 1991
1306 symtab.c Stored pervasive types in a structure and make
1307 lookup_pervasive_type() a lookup function that was based
1308 on working_lang. If lookup_pervasive_type() returned
1309 non-zero, then that value was returned (a fix, since
1310 before it simply wouldn't return the pervasive type.)
1311 language.h Added the macro CAST_IS_CONVERSION, which evaluates to
1312 non-zero if the language specified by working_lang means
1313 "conversion" when it says "cast".
1314 valops.c Added the function value_real_cast(), which performs a
1315 value.h *cast*, not a *conversion*, which is what value_cast()
1316 does when it can. In particular,
1317 value_cast(<float_type>,4) = 4.0, while
1318 value_real_cast(<float_type>,4) = some mess.
1319 eval.c Modula-2 builtin functions implemented: ABS, CAP, CHR,
1320 parser-code.c FLOAT, HIGH, MAX, MIN, ODD, ORD, TRUNC, and VAL.
1321 expression.h Added macros MAX_OF_TYPE and MIN_OF_TYPE to work with MAX
1322 and MIN on integral types. *NOTE*: These are currently
1323 hardcoded to work only if there are 8 bits per storage
1325 eval.c Made logical functions call value_bool to return a
1326 properly typed boolean value, based on working_lang.
1328 Thu Jun 20 11:55:27 EDT 1991
1330 valprint.c Types now print out in a Modula-2 fashion. This works for
1331 the cases when the type is printed out step-by-step, that
1332 is, it doesn't work when the name of a structured type
1333 (which includes the keyword "struct", etc.) is simply
1335 FIXME: Perhaps this is bad. Parts of it seem to kludgey,
1336 since type specifications in C and Modula-2 are very
1337 different. The C printing of a type is very recursive,
1338 whereas in Modula-2 it is generally very simple. C has
1339 type prefixes and suffixes, which have no real analogue in
1340 Modula-2. Maybe type_print() should call a language
1341 specific type printer. This is also advantageous if we
1342 compile GDB to exclude some of the languages. We'll just
1343 leave those functions out.
1345 Thu Jun 20 16:57:10 EDT 1991
1347 dbxread.c When reading the complete symbol table in (via
1348 psymtab_to_symtab()), the number and types of function
1349 arguments are added to a function type. define_symbol()
1350 calls add_param_to_type() to accomplish this.
1351 Assumption: when we come across a function definition
1352 (N_FUN symbol with an 'f' or 'F' in the name), its
1353 arguments will appear before another function definition.
1354 When a function is found, a pointer to its type is placed
1355 in the global in_function_type. Changes that
1356 add_param_to_type() makes are to this global.
1357 valprint.c The type of a function now includes (for Modula-2) the
1358 types of its parameters.
1359 eval.c Type checking and a check for the proper number of
1360 arguments is now done for function calls. Not sure of the
1361 impact this has on C++ member function yet.
1363 Thu Jun 20 19:58:48 EDT 1991
1365 valprint.c Rewrote the type printer. Broke it into two language
1366 specific parts, adding the functions type_print_m2() and
1368 An unfortunate consequence is this: if you debugging a C
1369 program in Modula-2 mode (why?), info types does not work
1370 well with regular expressions, since the types are printed
1371 out in Modula-2 terminology, but stored in C terminology.
1372 language.[ch] Added the functions new_type_last(), type_keyword(), and
1373 type_sep() to aid in the printing of typedefs.
1374 symtab.c Made the printing of typedefs as language independent as
1375 possible through calls to new_type_last(), type_keyword(),
1378 Fri Jun 21 11:50:26 EDT 1991
1380 dbxread.c Check all incoming ennumerated types. If it looks like
1381 Modula-2's BOOLEAN type, then change the type_code of the
1382 type to TYPE_CODE_BOOL so we can process it as a boolean
1384 valprint.c Replaced some of the 0x%x with calls to sprintf and
1385 hexformat() in val_print().
1386 language.[ch] Added the function hex_to_string(), which converts its
1387 integral argument to a hexadecimal number (format is
1388 language based) and returns the result as a string.
1390 Mon Jun 24 12:25:07 EDT 1991
1392 valprint.c Some functions call type_print_1() directly, instead of
1393 value.h using type_print(), so they can specify where (column) to
1394 print things. Since type_print() takes care of language
1395 dependence, that needs to be called first. Added a
1396 parameter depth to type_print() (so it is now like
1397 type_print_1). Changed type_print to type_print_at, and
1398 made type_print a macro that passes a depth argument of
1400 symmisc.c Changed all calls to type_print_1 to calls to
1402 Makefile.dist Made it possible to build GDB for a specific set of
1403 depend languages. Do this by passing a definition for the macro
1404 LANGS to make. LANGS should be a string containing a
1405 space-separated list of language names (ie. LANGS="c m2").
1406 The default is to build all languages. Note that grammar
1407 files must follow the naming convention of <lang>-exp.y.
1408 gdb.lang This holds the current value of the LANGS macro. It is
1409 examined every time make is called, and is updated if
1411 eval.c Added #ifdef _LANG_<lang> to these files.
1412 expread.c Still need to add them to dbxread.c and coffread.c.
1420 Mon Jun 24 16:33:11 EDT 1991
1422 language.[ch] Added the functions hexformat_pre() and
1423 hex_to_string_pre(), which take a prefix argument to
1424 include in the format string. Thus, hexformat_pre("08") will
1425 return "0x08x" (if the working language is language_c).
1426 Made hexformat() and hex_to_string() calls to the above
1427 with "" as the prefix argument.
1429 am29k-pinsn.c, arm-pinsn.c, breakpoint.c, convex-tdep.c, exec.c, core.c,
1430 dbxread.c, i386-pinsn.c, i386-stub.c, i386-xdep.c, i960-pinsn.c,
1431 infcmd.c, inflow.c, m68k-pinsn.c, m68k-stub.c, m88k-pinsn.c,
1432 mips-pinsn.c, mips-tdep.c, ns32k-pinsn.c, printcmd.c, pyr-pinsn.c,
1433 pyr-tdep.c, pyr-xdep.c, remote-vx.c, remote.c, solib.c, source.c,
1434 stack.c, sun386-xdep.c, symfile.c, symm-xdep.c, symmisc.c, tahoe-pinsn.c,
1435 valprint.c, vax-pinsn.c
1437 Changed all occurences of 0x%[0-9]*l*x in printf format strings to
1438 calls to hexformat() and hex_to_string(). Format strings without
1439 the leading "0x" were ignored.
1441 depend Updated to take the above into account.
1444 Tue Jun 25 15:27:18 EDT 1991
1446 symtab.h Added the types range_mode_t, range_check_t, type_mode_t,
1447 and type_check_t to keep track of the current state of
1448 range and type checking.
1449 main.c Added the variables range_mode, range_check, type_mode,
1450 and type_check to record the current state of range and
1451 type checking. Added initialization code to main().
1452 language.h Changed the macros STRICT_TYPE and RANGE_CHECK to examine
1453 the above variables.
1456 Tue Jun 25 17:57:08 EDT 1991
1458 dbxread.c process_one_symbol() updates the variable (enum language)
1459 source_lang based on the extension of the filename
1460 contained in the N_SO sybmol that started this symtab.
1461 When end_symtab() is called, the value of source_lang is
1462 put into the language field.
1463 stack.c select_frame() sets working_lang (and possibly type_check
1464 and range_check) to the language field of the symtab
1465 associated with the frame that is selected if working_mode
1466 is language_auto. If working_mode is language_manual, a
1467 warning is printed and working_lang is not set.
1468 language.c Added the function set_type_range(), which sets the value of
1469 type_check and range_check (if their modes call for
1470 automatic setting) based on the current value of
1471 working_lang. A non-zero argument will cause the current
1472 settings to be output.
1475 Wed Jun 26 14:51:40 EDT 1991
1477 eval.c Added range checks on assignment.
1478 m2-exp.y Added the grammar for sets to the language. Currently,
1479 these do not do anything except print an error message.
1481 Wed Jun 26 17:01:04 EDT 1991
1483 m2-exp.y Added the ability for parse_number() to parse negative
1484 numbers. A global flag is set upon encountering a unary
1485 minus. This was done to make, for example, 1 parse as a
1486 CARDINAL, and not as an integer, per Wirth's examples in
1487 Programming in Modula-2 ed.4.
1488 valprint.c Added support for "set radix 2" by then setting
1489 output_format to 't'.
1490 eval.c Implemented range checking on subrange types. Added calls
1491 to range_check_range_p for BINOP_ASSIGN and BINOP_VAL.
1492 Implemented MIN and MAX for ennumerated types. The
1493 minimum value of an ennumerated type is defined by Wirth
1494 as the first identifier, and the maximum as the last.
1495 m2-exp.y Made octal numbers ending with "B" be characters and those
1496 ending with "C" be numbers, per Wirth's book. (p. 34)
1498 Thu Jun 27 14:11:52 EDT 1991
1500 stack.c select_frame() now only sets working_lang, it does not
1501 notify the user. If working_mode is language_manual, then
1502 a warning is issued once.
1503 main.c At the end of each call to execute_command(), working_lang
1504 is checked against the local static (enum language)
1505 current. If they differ and working_mode is
1506 language_auto, the new settings of language, type and
1507 range checking are printed out.
1508 stack.c Modified frame_info() to include the language of the
1509 current frame in the output of "info frame".
1510 language.[ch] Added the function language_str() which returns the name
1511 of the current language.
1513 Fri Jun 28 15:33:14 EDT 1991
1515 m2-exp.y Added the built-in procedures INC, INCL, DEC, and DECL to
1516 the language. INCL and DECL currently cause an error,
1517 since sets are not implemented yet. INC and DEC are
1518 implemented as PREINCREMENT/PREDECREMENT with one
1519 argument, and as ASSIGN_MODIFY with two arguments.
1520 eval.c Added type checking to the above cases.
1521 value.h Added not_lval_constant to the lval_type ennumerated type.
1522 not_lval_constant means that the value is a constant
1523 value; that is 3 or 'a' or TRUE, not as in a constant
1524 identifier. This is used to help coerce numbers such as 3
1525 to either signed or unsigned numbers.
1526 valops.c Added the function value_coerce_constants() which coerces
1527 constant integers as following: if one is a constant and
1528 the other is not, the constant's type is set to the type
1529 of the other argument. If both are constants and one is
1530 signed, the other is converted to a signed constant.
1532 Sat Jun 29 17:26:29 EDT 1991
1534 valarith.c Added a better range checker. It now checks range
1535 (successfully) on integral operations [+-] (signed and
1536 unsigned) for any C sized type. Still does not work well
1537 for multiplication.)
1538 int_in_size() returns an integer that is coerced to fit into
1539 specified number of bytes.
1541 Mon Jul 1 13:04:14 EDT 1991
1543 language.[ch] Added the function binop_result_type(), which returns the
1544 builtin (struct type *) type that would be the result of a
1545 binop on the two values V1 and V2.
1547 Wed Jul 3 19:22:53 EDT 1991
1549 source.c Extended source_info() to include the source language in
1550 the output from "info source".
1552 Fri Jul 5 13:48:52 EDT 1991
1554 utils.c Moved the support functions for the GDB set/show commands
1555 dealing with language into language.c.
1556 language.c Added the function language_info(), which displays info
1557 about the current working language, type and range check
1558 settings. Called via the GDB command "info language".
1559 Added an initialization routine _initialize_language(),
1560 that sets defaults for the language, type and range
1561 variables and sets up the new GDB commands.
1562 main.c Language setup moved to language.c.
1565 Mon Jul 8 10:10:22 EDT 1991
1567 valarith.c Debugged the range checker for arithmetic. Still does not
1568 work for multiplication very well.
1570 Mon Jul 8 12:40:37 EDT 1991
1572 language.[ch] Added the function value_true() which returns non-zero if
1573 its argument represents a boolean true value.
1574 breakpoint.c Changed breakpoint_cond_eval() to call value_true() to
1575 check the truth of an expression.
1577 Thu Jul 11 12:51:34 EDT 1991
1579 language.[ch] Added the predicate structured_type(), which returns
1580 non-zero if the argument is a structured type.
1581 Added the predicate pointer_type(), which returns non-zero
1582 if the argument is a pointer type.
1583 eval.c Added the ability to do addition and substraction on
1584 pointers and integers. This case simply bypasses the
1587 Thu Jul 11 14:41:42 EDT 1991
1590 Added the symbol N_DEFD (0x4a) which is a definition
1591 module dependency that is used by the GNU Modula-2
1592 compiler and the linker. It is not important to GDB,
1593 except that [dbx|coff|mips]read.c should ignore these
1596 Fri Jul 12 16:07:00 EDT 1991
1598 valprint.c Changed the TYPE_LENGTH(type) >= 0 to TYPE_LENGTH(type) >
1599 0 in val_print(). Also added statements to the else part
1600 to coerce type (argument to val_print) to a pointer type
1601 if it is an "array of unspecified length".
1602 valops.c Added the function value_m2_string(), which returns a
1603 (value) value which is a constant string, whose type is
1604 (ARRAY [0..n] OF CHAR). The length field of the type
1605 structure is set to zero, so it will be interpreted as an
1606 "array of unspecified length".
1607 stack.c Moved the language/frame mismatch check to
1608 main.c:execute_command().
1609 main.c The working language is recorded each time
1610 execute_command() is executed. If working lang has
1611 changed during its execution, then the new
1612 language/type/range info is printed out for the user. If
1613 the working language does not match the language of the
1614 frame, a warning is issued.
1616 Sat Jul 13 16:16:39 EDT 1991
1618 eval.c Moved all the type-checking stuff for operators to
1619 language.[ch] language.c. This is so we can keep language-specific
1620 stuff (like for what type operators are defined) in
1622 language.[ch] Added the function binop_type_check(), which checks to see
1623 if its two (value) arguments are type-compatible with its
1624 opcode argument. The opcode should represent an operation
1625 involving an operator. Also added the macro function
1626 unop_type_check, which calls binop_type_check with a
1627 NULL second argument.
1628 expprint.c Added Modula-2 operators to the op_print_tab, so info
1629 expression.h break works correctly. Also added "op_string", which
1630 returns the string corresponding to the (enum exp_opcode)
1631 opcode that is its argument.
1634 Sat Jul 13 18:26:18 EDT 1991
1636 coffread.c Added code to record the type of function arguments with
1637 each paricular function. Code is very similar to that
1639 dbxread.c Moved add_param_to_type() to symtab.c
1640 symtab.[ch] Added function add_param_to_type() from dbxread.c
1642 *** NOTE: The above additions have not been tested.
1644 Mon Jul 15 12:50:47 EDT 1991
1646 langauge.[ch] Added the functions type_error and range_error, which work
1647 like error() except if the type/range mode is set to
1648 *_mode_warn, then they do not do a return_to_top_level(),
1649 but merely print a warning.
1650 Also changed [set|show]_[type|range]_command() to support
1651 the new "warn" feature.
1653 Thu Jul 18 17:50:54 EDT 1991
1655 mipsread.c Added code to record the type of function arguments with
1656 each particular function. Code is very similar to that
1659 *** NOTE: The above additions have not been tested.
1661 Fri Jul 19 11:19:10 EDT 1991
1663 defs.h Added macros MAX_OF_SIZE, MIN_OF_SIZE, UMAX_OF_SIZE, and
1664 UMIN_OF_SIZE, which when given a size of a numeric type,
1665 return the maximum and minimum value it can hold. UMAX...
1666 and UMIN... return the result for unsigned types.
1667 symtab.h Added the macros MAX_OF_TYPE and MIN_OF_TYPE to operate on
1668 struct types. They call above macros.
1669 dbxread.c Renamed the MAX and MIN_OF_TYPE macros to ..._OF_CTYPE to
1670 avoid a name conlict with the above.
1671 c-exp.y Added range checking on numeric constants in
1672 parse_number() for completeness.
1673 valarith.c Made binop_user_defined_p() and unop_user_defined_p()
1674 return 0 if working_lang is not language_c.
1676 Thu Aug 8 14:17:22 EDT 1991
1680 breakpoint.c Documentation strings of some commands changed to
1681 eliminate the references to the C language where
1684 Tue Aug 13 15:48:03 EDT 1991
1686 m2-exp.y Added qualified identifiers to the grammar. The semantics
1687 are slightly different from those of the GDB operator ::
1689 m2-exp.y Added a rule to each grammar of the form: start ::= exp |
1690 type_exp, where type_exp is any valid type expression.
1692 eval.c Added the opcode OP_TYPE, and an error case in eval.c.
1693 printcmd.c Modified ptype_command() so it actually parses the input
1694 (necessary for type expressions with scope qualifiers).
1695 Added the function ptype_eval() which expects an
1696 expression composed of one OP_TYPE element.
1697 *.[ch] Replaced all occurences of parse_c_expression with
1699 *.[ch] Replaced all occurences of parse_c_1 with parse_exp_1
1701 [End of ChangeLog entries from Andrew Beers for Modula-2 support.]
1703 Mon Sep 16 17:19:46 1991 John Gilmore (gnu at cygnus.com)
1705 Small fixes from Peter Schauer:
1707 * infrun.c (child_attach): Lint.
1708 * solib.c (find_solib): Handle shared libs version 2.
1710 Small fixes from David Wood:
1712 * xm-ultra3.h (SYS_SIGLIST_MISSING): Typo.
1716 * remote-vx.c: Move <stdio.h> to top, for FILE. Fix from
1717 John S <basrai%kanga.dnet@c3po.sm-alc.af.mil>.
1719 * utils.c (wrap_here): Avoid wrap action of fputs_filtered if
1720 chars_per_line is at maximum (user typed `set width 0'). Fix
1721 from Andreas Schwab <schwab@ls5.informatik.uni-dortmund.de>.
1723 Tue Sep 17 17:31:04 1991 Stu Grossman (grossman at cygnus.com)
1725 * coredep.c: include ptrace.h where necessary.
1726 * mipsread.c(parse_lines): fix unsigned char problem that was
1727 messing up line numbers on SGI's and possibly other MIPS based
1729 * infrun.c (child_create_inferior): use better test to check
1730 return val from setpgrp().
1731 * tm-irix3.h, xm-irix3.h, tconfig/irix3, xconfig/irix3: add these
1732 for sgi/irix support.
1734 Wed Sep 18 04:33:31 1991 Per Bothner (bothner at cygnus.com)
1736 * mipsread.c (parse_symbol): Put non-static procedures
1737 in the global block.
1739 Fri Sep 13 00:14:52 1991 John Gilmore (gnu at cygnus.com)
1741 Patch together `text_start' and `text_end' for 29K port.
1743 * exec.c (exec_command): If NEED_TEXT_START_END, define the
1744 variables and set them based on the exec file.
1745 * am29k-tdep.c: declare text_start.
1746 * valops.c (call_function_by_hand): declare text_end.
1748 * inferior.h: Eliminate CANNOT_EXECUTE_STACK in favor of
1749 defining CALL_DUMMY_LOCATION as BEFORE_TEXT_END. This is
1750 because machines that do this will also have to know to
1751 set NEED_TEXT_START_END. Besides, it was a redundant way to
1753 * tm-29k.h, tm-convex.h, tm-np1.h: Eliminate
1754 CANNOT_EXECUTE_STACK, define CALL_DUMMY_LOCATION and
1755 NEED_TEXT_START_END.
1757 Thu Sep 12 00:22:24 1991 John Gilmore (gnu at cygint.cygnus.com)
1759 AMD 29000 changes from David Wood <wood@david.ultra.nyu.edu>:
1761 * Makefile.in (CLIBS): Put XM_CLIBS and TM_CLIBS at end.
1762 Pass MUNCH_DEFINE to munch whenever we run it.
1763 * am29k-pinsn.c (print_insn): Handle NOP specially. Avoid %#x
1764 format string; use 0x%x instead.
1765 * am29k-tdep.c: Use DUMMY_SAVE_GREGS and RETURN_REGNUM.
1766 * ultra-xdep.c, xm-ultra.h: New files for Ultracomputer host system.
1767 * xm-rtbsd.h: New host support for RT/PC running BSD Unix.
1768 * inflow.c: Handle `short' process group IDs.
1769 * infptrace.c (fetch_register): Support CANNOT_FETCH_REGISTER,
1770 and check for ptrace errors.
1771 * coffread.c (SDB_REG_TO_REGNUM): Define if not already.
1772 (coff_symfile_init): Initialize text_bfd_scnum.
1773 (read_coff_symtab): Use it to find the text [and absolute?] sections.
1774 * ../config.sub: Add vendor nyu and os "sym[1-9]*".
1775 * configure.in: Add hosts rtpc-*-* and a29k-*-*.
1776 Merge target arm case with other "easy" cases. Add target
1777 cases a29k-*-none (rehack of am29k), a29k-*-kern (remote to
1778 Ultracomputer kernel), and a29k-*-sym1 (ultracomputer OS's user
1780 * minimon.h, remote-adapt.c, remote-mm.c: Add.
1781 * munch: Cope with RT/PC putting fns in data segment.
1782 Restore ability to override `nm' by specifying MUNCH_NM.
1783 * xconfig/rtbsd, xconfig/ultra3: New host systems.
1784 * tconfig/a29k: Rename from tconfig/am29k. Add remote-mm
1785 and remote-adapt. Remove encapsulated coff #define's (the
1786 support should go in BFD, and gdb shouldn't know or care).
1787 * tconfig/a29k-kern: Same, but for remote kernel debugging.
1788 * tconfig/ultra3: For debugging user processes on Ultra3/Sym1.
1789 * tm-29k.h: Update BADMAG (though it should go away).
1790 Allow the register definitions to be overridden in another
1791 tm-file. Fix SR_REGNUM. Add a mess of _REGNUM's. Separate
1792 RETURN_REGNUM from GR96_REGNUM and DUMMY_SAVE_GREGS from
1793 DUMMY_SAVE_GR96, for handling kernel calling conventions
1794 that use GR64+ rather than GR96+.
1795 * tm-ultra3.h: New file, for use on Ultra3 Unix as well as for
1796 remote debugging of Ultra3 kernel. Includes tm-29k.h and
1797 overrides various things.
1799 * remote-mm.c (mm_attach, mm_wait): Handle attach like
1800 child_attach does, making a clean stop in the newly attached
1802 * remote-eb.c: Lint.
1804 * coffread.c: Make coffread independent of any particular
1805 variant of COFF. Avoid #include-ing any particular one except
1806 internalcoff.h. BFD now passes key values for symbol reading
1807 as part of its coff_data structure (LINESZ, SYMESZ, AUXESZ,
1808 and the symbol masks and shifts); use them.
1809 Remove obsolete end_of_text_addr.
1811 * exec.c: Remove unused include files.
1813 Wed Sep 11 19:38:44 1991 John Gilmore (gnu at cygint.cygnus.com)
1815 * Makefile.in (documentation targets): Pass $(M4).
1816 Bugfix from eggert@twinsun.com (Paul Eggert).
1818 * stack.c (down_silently_command): Check for stack existence.
1820 Tue Sep 10 23:08:29 1991 John Gilmore (gnu at cygint.cygnus.com)
1822 * Makefile.in (VERSION): Update to 4.0.3.
1824 Tue Sep 10 09:19:29 1991 John Gilmore (gnu at cygint.cygnus.com)
1826 * core.c (core_file_command): Print frame at coredump with
1827 its level number, by calling print_stack_frame.
1828 * frame.h: Add selected_frame_level, print_stack_frame.
1829 * frame.h, stack.c: Remove print_sel_frame, print_selected_frame.
1830 * convex-tdep.c, convex-xdep.c, infcmd.c, inflow.c, infrun.c:
1831 Change print_sel_frame and print_selected_frame callers to
1834 * dbxread.c (read_ofile_symtab): Avoid empty else clause.
1835 * symfile.c (free_named_symtabs): Ditto.
1836 * main.c (main): wrap_here needs an arg.
1837 * solib.c (find_solib): Avoid memory access if _DYNAMIC is zero.
1838 (solib_add): Avoid noise.
1839 (solib_create_inferior_hook): Lint.
1840 (sharedlibrary_command): Move dont_repeat to here.
1841 * utils.c (error): Call wrap_here to force buffered output.
1843 Small patches from Peter Schauer:
1845 * coffread.c (start_symtab): Free any existing line_vector before
1847 (read_coff_symtab): Ditto for type_vector.
1849 * source.c (lines_to_list): New variable, replacing function.
1850 (all uses): Use as variable.
1851 (_initialize_source): Add 'set listsize' and 'show listsize'.
1852 * utils.c (lines_to_list): Remove function.
1853 * stack.c (print_frame_info): Use as variable.
1854 * defs.h (lines_to_list): Remove declaration.
1856 Mon Sep 9 13:45:57 1991 John Gilmore (gnu at cygint.cygnus.com)
1858 * breakpoint.c (insert_breakpoints): Restore warning about
1859 the program might be running in another process, but only for
1860 systems with this brain death (#ifdef ONE_PROCESS_WRITETEXT).
1861 * xm-hp300bsd.h, xm-mips.h, xm-vax.h: Define it.
1863 * utils.c (error): if error_pre_print is set, print the string
1865 * main.c (main, print_gnu_advertisement, print_gdb_version):
1866 Reformat legalese so it always prints, but acts as an "I'm here"
1867 message while symbols are being read. If any errors occur,
1868 print a few newlines to set off the message and start it at the
1869 left margin. Remove mention of "help" command, and don't yak
1870 about symbol reading.
1871 (catch_errors): Error string is now printed first in case of
1873 * command.c (undef_cmd_error, lookup_cmd): On undefined command,
1874 suggest the "help" command.
1876 * Makefile.in (VERSION): Set to 4.0.2.
1878 Thu Sep 5 23:49:48 1991 John Gilmore (gnu at cygint.cygnus.com)
1880 * .gdbinit: Remove useless "rr" command. Set complaints
1881 to 1 for people debugging gdb.
1883 * breakpoint.c, remote-vx.c: Reword strings printed by
1884 catch_errors callers.
1886 Wed Sep 4 11:07:50 1991 John Gilmore (gnu at cygint.cygnus.com)
1888 * WHATS.NEW: "history write -> history save". Doc "write on/off".
1889 (Fix from kenc@viewlogic.com.)
1891 Fix some infrastructure to be able to cope with host and target
1892 machines with different sized basic types (ints, ptrs, etc).
1893 (Idea from pierre@la.tce.com (Pierre Willard).)
1895 * values.c (value_from_longest): Rename from value_from_long.
1896 Handle pointer types as well as integers, so that targets with
1897 different pointer sizes from the host can be accomodated.
1898 * breakpoint.c, convex-tdep.c, eval.c, expprint.c, printcmd.c,
1899 valarith.c, valops.c, valprint.c, value.h, values.c: Rename
1900 uses of value_from_long to value_from_longest.
1901 * eval.c, findvar.c, printcmd.c, valarith.c, valops.c: Pass
1902 the correct pointer type to value_from_long{est}.
1904 * doc/gdb.texinfo ($_, $__): Describe types of these variables.
1906 * remote-vx.c: Remove obsolete code for calling functions via
1907 vxworks kludge interface (it referenced value_from_long).
1909 * valops.c (value_string): Find malloc with lookup_misc_func, not
1912 Tue Sep 3 18:37:46 1991 John Gilmore (gnu at cygint.cygnus.com)
1914 Make writing to files work properly. (Fixes to BFD are also needed.)
1916 * core.c (core_open): Open file ourselves, read or r/w, depending on
1917 write_files. Use bfd_fdopenr.
1918 * gdbcore.h (write_files): New variable.
1919 * exec.c (write_files): Define variable, add set&show for it.
1920 (exec_file_command): Use write_files to open for read or r/write.
1922 Make shared library reading happen automatically. These changes
1923 are mostly from Peter Schauer <pes@regent.e-technik.tu-muenchen.de>.
1925 * inferior.h (stop_soon_quietly): Add to exported variables.
1926 * infrun.c (child_create_inferior): call solib hook, if defined.
1927 (child_attach): call solib hook, if defined.
1928 * solib.c: Include inferior.h. Add from_tty to so_list as kludge.
1929 (find_solib): Use lookup_misc_func rather than hand-rolled.
1930 (symbol_add_stub): New stub for catch_errors.
1931 (solib_add): Avoid output if !from_tty. Catch errors rather
1932 than just calling symbol_file_add and bombing.
1933 (solib_create_inferior_hook): Interface with the target process
1934 to let it read and alloc shared libs, then figure out what it did.
1936 * core.c (validate_files): Fix typo, soften warning.
1937 (Fix from Hiroto Kagotani <kagotani@cs.titech.ac.jp>.)
1939 * utils.c (fputs_demangled): Avoid duplicate printing if
1940 demangling is off. (Fix from J.T. Conklin <jtc@cayenne.com>.)
1942 * infrun.c (proceed): Cast -1 to (CORE_ADDR) before comparing.
1943 (Fix from pierre@la.tce.com (Pierre Willard).)
1945 * main.c (catch_errors): Change argument to a char * from an int,
1946 since a char * can point to a struct full of glop, but an int
1947 is not guaranteed to be able to hold a pointer.
1948 * breakpoint.c (breakpoint_cond_eval, bpstat_stop_status,
1949 breakpoint_re_set_one, breakpoint_re_set): Adapt.
1950 * core.c (core_open, solib_add_stub): Adapt.
1951 * remote-vx.c (symbol_stub, add_symbol_stub, callers): Adapt.
1953 Wed Aug 28 18:18:05 1991 John Gilmore (gnu at cygint.cygnus.com)
1955 * Makefile.in: Update VERSION to 4.0.1. Evade GNU Make bug
1956 by adding .NOEXPORT target.
1958 Fri Aug 23 17:14:25 1991 John Gilmore (gnu at cygint.cygnus.com)
1962 * Makefile.in (VERSION): Roll to 4.0.
1963 (gdb.tar.Z): Make refcard.ps as well, for shipment.
1965 Fri Aug 23 14:07:09 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1967 * doc/gdb.texinfo: minor rewordings, crossref to ptype from print,
1970 * doc/Makefile, Makefile.in: generate "gdb-all.texi" rather than
1973 * doc/rdl-apps.texi: renamed from rdl-apps.texinfo
1975 * Makefile.in, doc/Makefile, doc/.Sanitize, doc/gdb.texinfo:
1976 reflect above name change
1978 * WHATS.NEW: correct pointer to refcard.
1980 * doc/gdb.texinfo: update New Features, Installing
1982 * doc/gdbint.texinfo: add short description of configure +template
1984 Fri Aug 23 11:46:08 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1986 * doc/gdb.texinfo: update, fix bugs in "Installing" appendix
1988 Fri Aug 23 01:02:00 1991 John Gilmore (gnu at cygint.cygnus.com)
1990 * Makefile.in: Add config.sub, make doc/rdl-apps.texinfo for
1991 tar file, add dependencies for referenced doc files.
1993 Thu Aug 22 22:17:06 1991 Stu Grossman (grossman at cygint.cygnus.com)
1995 * coffread.c, symfile.c, stack.c: saberized.
1997 Thu Aug 22 16:20:27 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1999 * doc/refcard.tex: permuted Essential Commands sec
2001 * doc/gdb.texinfo: new C++ chapter; revised installation appendix;
2003 set/show symbol-reloading
2004 default set complaints 0
2006 RET-repeat disabled after prompted long displays
2007 processID (attach) interpretation of 2nd GDB cmdline arg
2009 Thu Aug 22 14:05:47 1991 Stu Grossman (grossman at cygint.cygnus.com)
2011 * expread.y, coffread.c, dbxread.c, target.c, mem-break.c,
2012 cplus-dem.c, values.c, valprint.c, symfile.c, remote.c,
2013 breakpoint.c, main.c: lint.
2015 Thu Aug 22 02:02:26 1991 John Gilmore (gnu at cygint.cygnus.com)
2017 Install new configuration scheme for GDB and friends.
2019 * config.sub: Translate ordinary names to three-part names.
2020 * configure: Use three-part names internally.
2021 * configure.in: Translate three-part names to filenames.
2023 * README, WHATS.NEW: Update for gdb-4.0.
2024 * Makefile.in: Roll VERSION to 3.99.
2026 Wed Aug 21 18:21:09 1991 John Gilmore (gnu at cygint.cygnus.com)
2028 * infptrace.c (KERNEL_U_ADDR_BSD): Include a.out.gnu.h.
2029 * i960-tdep.c, m68k-tdep.c, sparc-tdep.c, tm-i960.h,
2030 tm-m68k.h, remote-nindy.c: Change ext_format_XXX structs
2031 to single structures rather than arrays; when passing
2032 their address, use &. This avoids trouble with bdead compilers.
2033 * mcheck.c: Don't include <stdlib.h>; just declare "void abort();"
2034 instead. This avoids portability headaches.
2035 * mips-tdep.c (mips_do_registers_info): Only print FP regs if
2037 * source.c (open_source_file): Avoid ANSI const bdeath by
2038 skipping declaration and then casting result value.
2039 * tm-hp300bsd.h: Clarify comment.
2040 * utils.c (strstr): Result is const char *; ANSI bdeath.
2041 * xm-hp300bsd.h: Define HOST_BYTE_ORDER. Redefine INT_MIN,
2042 since system include file defines it differently from "defs.h",
2043 though the two are equivalent for our purposes.
2044 * tconfig/hp300bsd: Add m68k-tdep.o.
2046 Tue Aug 20 16:01:11 1991 John Gilmore (gnu at cygint.cygnus.com)
2048 * tconfig/sun*4: Remove warnings about system assembler.
2050 Mon Aug 19 13:44:46 1991 John Gilmore (gnu at cygint.cygnus.com)
2052 * mcheck.c: Avoid warning about undeclared abort fn.
2053 * tm-sparc.h (PC_ADJUST): Avoid calling error() from this;
2054 it causes recursive calls to error() when used in cleanups.
2055 To do so requires that we make it a function, so we do.
2056 * sparc-tdep.c (sparc_pc_adjust): New implem of PC_ADJUST.
2057 * utils.c (do_cleanups): Remove the current cleanup from the
2058 chain *before* calling it, in case error() is called from it.
2059 The result won't be pretty, but won't be an infinite loop either.
2061 Mon Aug 19 00:41:04 1991 Michael Tiemann (tiemann at cygint.cygnus.com)
2063 * dbxread.c (read_struct_type): Grok anon structs for C++.
2064 (vb_name, vptr_name): Null terminate these strings.
2066 Fri Aug 16 08:31:03 1991 John Gilmore (gnu at cygint.cygnus.com)
2068 Minor bug fixes from BSD Net2 gdb:
2070 * blockframe.c (get_prev_frame_info): If FRAME_CHAIN_COMBINE
2071 returns 0, there is no previous frame.
2072 * breakpoint.c (commands_command): If !from_tty, don't call
2073 input_from_terminal_p().
2074 * dbxread.c (record_misc_function): Speed up slightly.
2075 (compare_psymbols): Ditto.
2076 * infcmd.c (do_registers_info): Take a second argument to
2077 determine whether to print float registers. "info registers"
2078 does not do so anymore. "info all-registers" does, now.
2079 * mips-tdep.c, pyr-tdep.c (xxx_do_registers_info): Take second
2081 * tm-mips.h, tm-pyr.h (DO_REGISTERS_INFO): Pass second arg.
2082 * inflow.c (initialize_inflow): Set tflags_ours correctly.
2086 * breakpoint.c (bpstat_do_actions): Use a cleanup to restore
2087 executing_breakpoint_commands if we are interrupted by error.
2088 * coffread.c (init_lineno): Avoid problem with zero-sized linetab
2089 versus malloc/free. From: john@labtam.labtam.oz.au (John Carey).
2090 * core.c (solib_add_stub, core_open): Call SOLIB_ADD inside a
2091 catch_errors() so we can setup the frame regardless of whether
2092 the shared libs work.
2093 * ieee-float.c (double_to_ieee_extended): Get exponent from
2094 right place in little-endian systems. From John Carey.
2096 Thu Aug 15 18:43:57 1991 John Gilmore (gnu at cygint.cygnus.com)
2098 * main.c: Remove unused terminating_signals and catch_termination().
2099 (long_options): Terminate with a zero element.
2100 [Bugfix from Atsuo Kawaguchi <atsuo@hark86.harl.hitachi.co.jp>.]
2101 (gdb_readline): Make call-compatible with readline.
2102 (init_signals): Improve comments re vfork vs. signal.
2104 * utils.c (prompt_for_continue): Use new gdb_readline().
2105 If we prompt for continuation, we don't let CR repeat the previous
2106 command, once we get back to a prompt. It's too easy to keep
2107 hitting CR, expecting "--more--" prompts, and have some long
2108 command start repeating on you.
2110 Tue Aug 13 16:17:56 1991 John Gilmore (gnu at cygint.cygnus.com)
2112 * blockframe.c (frameless_look_for_prologue): Speed up by
2113 calling SKIP_PROLOGUE_FRAMELESS_P if it's defined.
2114 * tm-sparc.h (SKIP_PROLOGUE, SKIP_PROLOGUE_FRAMELESS_P):
2115 Define two variants, one faster.
2116 * sparc-tdep.c (sparc_frame_chain): Use target_read_memory
2117 and return zero, rather than giving an error.
2118 (setup_arbitrary_frame): Initialize the PC in the new frame.
2119 (skip_prologue): Add a second arg saying whether we're just
2120 checking for a frameless function or not.
2122 * core.c (core_open, core_close, core_xfer_memory): Move
2123 section table pointers and bfd* into the target_ops.
2124 (core_open): Allow errors in shared lib reading, etc.
2125 (core_files_info): Describe shared library sections.
2127 * exec.c (exec_open, exec_close, exec_xfer_memory, xfer_memory,
2128 exec_files_info, set_section_command): Move section table
2129 pointers and bfd* into the target_ops.
2130 (add_to_section_table): Add BFD to section table.
2132 * target.c (target_xfer_memory, target_info): Pass target to
2133 xfer_memory and target_info functions.
2136 * gdbcore.h: Move struct section_table.
2137 * target.h: New home of struct section_table.
2139 * solib.c (solib_add): New argument is the target_ops whose
2140 section list is to be added to, if any. Reallocate the
2141 sections in that target to add any that come from shared libs.
2142 (throughout) so_sections renamed to sections.
2143 (solib_xfer_memory): Deleted.
2144 * tm-sunos.h (SOLIB_ADD): Add target argument.
2145 (SOLIB_XFER_MEMORY): Delete.
2147 * core.c, exec.c, inftarg.c, remote-eb.c, remote-nindy.c,
2148 remote-vx.c, remote.c, target.c, target.h: Remove add_syms vector
2149 from target_ops. It's the same on all targets. Add two section
2150 pointers to target_ops.
2152 * stack.c (find_relative_frame): Dump ancient algorithm for
2153 "down", just use handy "next" pointers.
2154 (frame_command): Don't error if there is no stack; let user
2157 * inflow.c (new_tty_prefork, new_tty): New prefork routine
2158 modifies static state in the parent process; new_tty itself
2159 runs in the child and modifies the child's file descriptors
2160 to match the saved static state.
2161 * infrun.c (child_create_inferior): Call new_tty_prefork,
2164 * infptrace.c (child_xfer_memory): Add ignored target arg.
2165 * remote-eb.c (eb_xfer_inferior_memory): ''
2166 * remote-nindy.c (nindy_xfer_inferior_memory): ''
2167 * remote-vx.c (vx_xfer_memory): ''
2168 * remote.c (remote_xfer_memory): ''. Rename from
2169 remote_xfer_inferior_memory.
2171 * main.c (main): Only try to attach "corefile" argument if
2172 it starts with a digit.
2174 * symfile.c (symbol_reloading): New "set/show" variable.
2175 (symbol_file_add): Shorten message about symbol reading.
2176 (add_symbol_file_command): Merge with add_syms_addr_command,
2177 since this should work on all targets now.
2178 (stop_whining): Default to zero, to shut up complaints
2179 about bad symbol tables on many systems.
2180 (free_named_symtabs): Just exit unless symbol_reloading.
2182 * xm-sun3os4.h, xm-sun4os4.h: Define BROKEN_LARGE_ALLOCA,
2183 and add comment explaining shared library screw.
2185 * source.c: #if defined => #ifdef.
2187 Thu Aug 8 12:23:19 1991 John Gilmore (gnu at cygint.cygnus.com)
2189 * doc/gdbint.texinfo: Improve doc on porting to new OS's.
2191 Tue Aug 6 17:16:15 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
2193 * doc/rdl-apps.texinfo: provide default readline-appendix finder
2194 (doc/Makefile knows how to make one for local config)
2196 * Makefile.in: use doc/Makefile for doc targets
2198 * doc/Makefile: GDB documentation now has its own Makefile
2199 doc/refcard.tex: renamed from "gdbrc.tex"
2200 doc/.Sanitize: add Makefile; recognize renamed refcard.tex
2201 doc/gdbint.texinfo: add markup in "Cleanups" chapter
2204 Fri Aug 2 00:13:06 1991 John Gilmore (gnu at cygint.cygnus.com)
2206 * values.c (baseclass_addr): When reading target memory, use the
2207 length of the basetype, not the upper type. We've only malloc'd
2208 enough space for the basetype, leading to errors in free().
2210 * expprint.c (print_subexp): Print UNOP_MEMVAL of an OP_LONG that
2211 ends up as a function specially, since we know the actual type of
2212 the pointed-to address. This (somewhat) fixes display of
2213 expressions that include misc_function_vector names. Try `cond 1
2214 !strcmp("a","b")' then `i b'.
2216 * infrun.c: Move DO_DEFERRED_STORES from proceed() to resume().
2217 The child can be proceeded from inside wait_for_inferior in
2218 evaluating breakpoint conditions, and DO_DEFERRED_STORES was
2219 getting skipped in that case.
2221 * expprint.c (print_subexp): Use filtered output, since the
2222 subroutines we call use it, otherwise the output is horribly
2223 mangled, since output of wrappable stuff comes out late.
2225 * Makefile.in: Bump VERSION to 3.98.1
2227 * infrun.c (child_create_process): Use execlp to find the
2228 shell to exec our target program. This requires some fiddling
2229 with `environ' since there is no execlpe().
2231 Thu Aug 1 15:35:17 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
2233 * Makefile.in, doc/gdbrc.tex, doc/rc-* (new files):
2234 Minor rearrangement of refcard permits two new make targets--
2235 gdbrc.dvi DVI output for refcard, using CM fonts
2236 gdbrc.ps PostScript refcard, using PS fonts
2238 Wed Jul 31 16:46:21 1991 John Gilmore (gnu at cygint.cygnus.com)
2242 * TODO, Projects, WHATS.NEW, README: Update for gdb-3.98.
2243 * Makefile.in (gdb-all.texinfo): Avoid touching file if M4 dies.
2245 Wed Jul 31 16:35:58 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
2247 * doc/gdb.texinfo: last changes for release.
2248 Minor typo and formatting fixes; incorporated most fixes remaining from
2249 filed mail commenting on earlier drafts.
2251 Added warnings: pipes don't work in run command;
2252 conditions are converse of assertions;
2253 step over fn without debug info goes to next fn;
2254 vars may have "wrong" values near fn entrance, exit
2256 Added example from Kingston on printing repeated nonadjacent values
2258 Added explicit mention that in Emacs gdb mode C-c and C-z are like
2259 shell mode for signals
2261 Renamed "Stepping and Continuing" to "Continuing and Stepping" so it
2262 doesn't sound so much like its parent "Stopping and Continuing"; also
2263 moved entries on continue to top of section, so they don't get lost.
2265 Improved installation directions in appendix, added manual formatting
2268 Tue Jul 30 17:26:39 1991 John Gilmore (gnu at cygint.cygnus.com)
2270 * configure.in: Remove xm.h and tm.h even if we aren't linking
2271 new ones, so "./configure sun4; ./configure none" does the right
2272 thing. Assume that alldeps.mak and depend are already built in
2273 srcdir, and avoid running "make" (particularly "make depend",
2274 which involves "gcc") from inside configure. Build Makefile
2275 directly rather than building Makefile.conf first.
2276 * configure: Regenerate with above changes.
2277 * Makefile.in: Use $(BISON) to find bison. Roll VERSION
2278 to 3.98. Revise gdb.tar.Z procedure to produce a file
2279 called gdb-$(VERSION).tar.Z but which unpacks into a
2280 directory called "gdb". Move non-source files out of
2281 $(SFILES_SUBDIR). Pretty up alldeps.mak with comments.
2282 (depend): Don't try to do "gcc expread.y".
2283 (expread.o): Update dependencies by hand.
2285 Mon Jul 29 15:21:09 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
2288 Fixed a variety of small typos that prevented info from formatting
2289 cleanly; altered too-long heading for GPL Appendix, as discussed
2290 w/RMS; Changed date on cover to July 91.
2292 Fri Jul 26 13:20:02 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
2295 (1) Applied some fixes due to comments from Larry Breed (easier ones
2296 through chapsec 5.2)
2297 (2) Eliminated use of @footnote---had my doubts about it anyways, and
2298 it's broken in latest texinfo
2299 (3) Introduced *some* use of [] for optional arguments, where
2300 explanation is not simpler by listing cmd w arg and cmd w/out arg
2301 separately. Still not using @deffn.
2302 (4) Dropped in GPL-2. NOTE: one of GPL-2 or texinfo is broken; a
2303 couple of headings are too long. Need patches to texinfo or revision
2306 * Partial update to README (which still needs work for this
2307 release!): (1) use of configure corrected for new script,
2308 (2) "make gdb.dvi" and "make gdb.info" mentioned.
2310 Wed Jul 24 06:44:02 1991 John Gilmore (gnu at cygint.cygnus.com)
2312 * symtab.c (lookup_symbol): Don't complain right off about
2313 no debug symbols; use the misc function vector first.
2314 (list_symbols): Use misc function vector to find symbols
2315 that don't have debug info, and print them.
2316 (find_pc_symtab): Temporarily avoid fatal() when psymtab
2317 PC range doesn't match symtab PC range, as it does on the
2318 MIPS because our symtab reading isn't perfect.
2320 * dbxread.c (dbx_symfile_read): Make warning about
2321 "no debug symbols" slightly nicer.
2323 * source.c (select_source_symtab): If "main" symbol exists,
2324 but decode_line_spec can't find line info, don't just return
2325 a zero; try other source symtabs or give an error.
2327 * mipsread.c (parse_partial_symbols): Sort the psymtabs by
2328 their low addresses first, then rip through fixing high addrs.
2330 * ns32k-opcode.h (sfsr): Bugfix from Rune Nerg}rd,
2331 <runene@ifi.uio.no>.
2332 (NS32K_SVC_IMMED_OPERANDS): Reverse the #ifndef.
2334 Tue Jul 23 18:52:43 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
2336 * Minor, mostly mechanical, cleanup of doc subdir for clean
2337 makeinfo'ing and TeXing; also ensured gdb-all.texinfo (post-m4)
2338 and gdb.info (post- texinfo2 makeinfo) generated for distribution.
2340 Sun Jul 21 03:54:52 1991 John Gilmore (gnu at cygint.cygnus.com)
2342 Mostly MIPS and general symbol-reading fixups.
2344 * doc/gdbint.texinfo: Add documentation on symbol-reading
2347 * mipsread.c: Remove kludges around #include "ecoff.h".
2348 Remove redefinitions of a_magic, etc, no longer used.
2349 (parse_symbol, ): Convert "Internal:" printfs to complain()ts.
2350 Fix global overview comments to match symfile.c protocol.
2351 (mipscoff_new_init): Eliminate cur_hdr if we have one.
2352 (mipscoff_symfile_read): Eliminate unused code. Avoid
2353 sorting all the symtabs, when all we have read here is psymtabs.
2354 The symtabs are sorted as they are created anyway. Tell
2355 condense_misc_bunches whether we're mainline.
2356 (psymtab_to_symtab_1): Pass filename when recursing, to make
2357 stack trace more informative.
2358 (parse_partial_symbols): Assume cur_hdr as argument.
2359 (read_mips_symtab): Don't clobber cur_hdr, so it can be freed.
2360 Pass cur_hdr implicitly to parse_partial_symbols. Avoid checking
2361 the TYPE_NAME of char *, since that's done in symfile.c.
2362 (free_numargs, parse_symbol, add_symbol, add_block,
2363 shrink_linetable): Declare these fns void.
2364 (upgrade_type): Convert tree of if's to switch. Clean up
2365 bogus "off == 0" handling with a complaint. Avoid setting
2366 field bitpos and bitsize of array with lower and upper bounds.
2367 Check specified bitsize of elements against their actual type's
2368 bitsize, and complain if different. Complain about unknown
2370 (parse_fdr): Don't assume sizeof(char *) == sizeof (struct *).
2371 (psymtab_to_symtab_1): Print names of subsidiary files that
2372 are being read in. FIXME, we read far too many files. This code
2373 is not the problem, the problem is in parse_fdr where the psymtabs
2375 (cross_ref): Result should indicate that we used one aux entry
2376 normally, or two if we encountered a "next" entry. This used
2377 to leave the caller pointing at the wrong aux entry.
2378 (add_symbol): If overflowed cur_block, reallocate it larger,
2379 chase all pointers to it, and complain(), rather than clobber memory.
2380 (shrink_block): Use xrealloc rather than xmalloc-and-copy.
2381 (new_field): Only allocate one field initially, not two.
2382 Pull ++ out of macro argument. Simplify.
2383 (_initialize_mipsread): Avoid initialization of importd
2384 global_psymbols and static_psymbols.
2386 * symfile.c (psymtab_to_symtab): Depend on XXX_psymtab_to_symtab
2387 to properly set pst->symtab; avoid searching for it.
2388 (symfile_fns): Improve comments, add a FIXME.
2389 * dbxread.c: Update comments to reflect symfile protocol.
2390 (read_ofile_symtab, end_symtab): Return the symtab.
2391 (psymtab_to_symtab_1): Set pst->symtab.
2393 * coffread.c (coff_symfile_read): tell condense_misc_bunches
2394 whether we're mainline.
2396 * symfile.h (sym_fns): Remove unused sym_discard member.
2397 * coffread.c, mipsread.c, dbxread.c: Remove XXX_symfile_discard.
2399 * mtrace.c (mtrace): Take effect if mallwatch is set, even if
2400 the environment variable is not.
2401 * infcmd.c (finish_command): Use filtered printfs.
2402 * cplus-dem.c: Add struct tags to a few unnamed structs.
2403 * valops.c (value_coerce_array): Improve comments.
2404 * valprint.c (type_print_varspec_suffix): Print array size only
2405 if greater than zero.
2406 * m88k-tdep.c: Shift some lines left by one space, that had
2407 apparently been trashed at some point.
2408 * TODO: More things to do, a few got done.
2410 Thu Jul 18 22:46:05 1991 John Gilmore (gnu at cygint.cygnus.com)
2412 * symtab.h (LOC_EXTERNAL): Eliminate in favor of LOC_STATIC.
2413 (ldsymoff, ldsymlen, globals_offset, statics_offset): Improve
2415 * dbxread.c (read_dbx_symtab): LOC_EXTERNAL -> LOC_STATIC.
2416 * expread.y, findvar.c, symmisc.c: Ditto.
2417 * printcmd.c (address_info): Update printed forms of LOC_
2418 symbols. Elim LOC_EXTERNAL.
2419 (print_frame_args): Keep track of param stack offsets before
2420 re-looking up to find the local register param is kept in.
2422 * mipsread.c: Use <symconst.h> and <sym.h> rather than <syms.h>.
2423 Further integration of mipsread into gdb. Eliminate unused
2424 routines, duplicate declarations. Handle static symbols in
2425 psymtabs as well as external symbols. When reading symtabs,
2426 insert symbols into the correct block (global, static, or a local
2428 (read_mips_symtab, parse_partial_symbols): Don't pass useless
2430 (mipscoff_symfile_read): Don't call select_source_symtab.
2431 (parse_symbol): Use SYMBOL_VALUE_ADDRESS where appropriate,
2432 rather than SYMBOL_VALUE.
2433 (parse_external): Comment clobbering of top_stack.
2434 (parse_partial_symbols): Update comments. Allocate and parse
2435 static symbols as well as external symbols. FIXME, enum values
2436 are not handled in this pass, but should be. Inline new_psymbol.
2437 Use SYMBOL_VALUE_ADDRESS.
2438 (psymtab_to_symtab_1): Read symbols into global static block
2439 by default (until enter some function's local block context).
2440 (sort_blocks): Clean up STATIC_BLOCK as well as GLOBAL_BLOCK.
2441 (destroy_all_symtabs, new_psymbol): Eliminate, unused.
2443 * source.c (select_source_symtab): Select a source symtab
2444 from either the symtabs or, failing that, the psymtabs.
2445 (list_command): Update error message.
2446 (forward_search_command, reverse_search_command): Use getc, not
2447 fgetc, for speed. FIXME, add comment about buffers that die if
2448 overrun by long line.
2450 * values.c (unpack_field_as_long, modify_field): Avoid shifting
2451 by an entire word, which is not portable, if we have a 32-bit
2452 field. (Code in dbxread.c already turns such bitfields, if
2453 aligned, into ordinary ints, but fixing this will help for other
2454 symbol formats and for future changes.)
2455 * core.c (core_open): Handle ANSI const brain death.
2456 * utils.c (vprintf): Fix varargs typo.
2458 Sun Jul 14 00:42:53 1991 John Gilmore (gnu at cygint.cygnus.com)
2460 * findvar.c (find_var_value): Handle &function better.
2461 * TODO: Document work needed on &fn and &array.
2462 * printcmd.c (print_address_symbolic): New arg is the prefix
2463 to print if a name is printed.
2464 (print_address_demangle): Honor "set print address" now.
2465 Use new arg above to improve spacing of output.
2466 * valprint.c (val_print): When printing function pointers,
2467 print symbolic form too.
2468 * breakpoint.c (breakpoint_1): Use new print_address_symbolic.
2470 Mon Jul 8 19:02:46 1991 John Gilmore (gnu at cygint.cygnus.com)
2472 * core.c (memory_error): Reword error msg to mislead less.
2474 * mips-pinsn.c (print_insn_arg 'd'): Print $ with reg name.
2476 * mipsread.c (read_mips_symtab, read_the_mips_symtab,
2477 parse_partial_symbols): Use newer BFD internals (external_filehdr
2478 and external_aouthdr), byte-swap the fields that we care about
2479 before using them, and make the file header data local to
2480 read_the_mips_symtab rather than global.
2482 Sat Jul 6 01:34:15 1991 John Gilmore (gnu at cygint.cygnus.com)
2484 * ns32k-opcode.h (movmw, movmd): Fix opcodes. Bug fix
2485 from Rune Nerg}rd <runene@ifi.uio.no> on 5 Jul 1991.
2487 * main.c (command_line_input): Flush stdout and stderr
2488 before every call to readline. This reportedly fixes a bug
2489 that comes up in Sys V running emacs-gdb and/or xxgdb,
2490 when stdin/out are pipes or sockets.
2492 Thu Jul 4 14:47:06 1991 John Gilmore (gnu at cygint.cygnus.com)
2494 * configure.in, Makefile.in: Avoid rebuilding "depend" as much.
2495 Avoid declaring Makefile dependencies, because GNU Make stupidly
2496 tries to update it if we do.
2498 * coffread.c: Revise for minor changes to bfd internal coff
2501 * configure: If -template= is given a relative path, make it
2502 absolute before recurring in subdirectories.
2504 * configure, configure.in, Makefile.in: Install "configure" script
2505 as replacement for config.gdb.
2506 * config.gdb, Makefile.dist, Makefile.sdir: Remove
2507 * README: Update for configure, mostly. FIXME.
2509 * Add dec3100 as equivalent to littlemips. Indicate in all host &
2510 target config files that they are for the host. When the lines
2511 get copied into the Makefile, this makes it more obvious what's
2514 Mon Jun 24 23:49:07 1991 John Gilmore (gnu at cygint.cygnus.com)
2516 * sparc-opcode.h (trap opcodes): Avoid leading spaces or
2517 tabs, which end up in the disassembler output inadvertently.
2519 Wed May 29 23:01:03 1991 John Gilmore (gnu at cygint.cygnus.com)
2521 Make it compile cleanly in an ANSI GCC2 environment.
2523 * blockframe.c: <stdio.h>
2524 * cplus-dem.c: free takes a void *, ifdef __STDC__
2525 * dbxread.c (read_huge_number): avoid gcc2 bug hoisting calc of
2527 * defs.h (alloca): Avoid doing anything if alloca already def'd.
2528 * stddef.h, stdlib.h: Remove these files.
2529 * symtab.c: Avoid declaring qsort, close.
2530 * symfile.c: Avoid declaring close.
2531 * utils.c (vprintf): Declare "ap" arg as proper va_alist.
2532 * sparc-tdep.c: Avoid including lots of Sun-host-specific files.
2534 Assorted other changes.
2535 * dbxread.c: include "libaout.h", not "liba.out.h".
2536 * printcmd.c (print_frame_args): Set recurse properly for
2537 indentation of struct and array parameters.
2538 * valops.c (value_cast): Allow cast to void.
2539 * infrun.c (resume): If NO_SINGLE_STEP, call machine dependent
2540 single_step() in a target-independent fashion.
2541 * sparc-tdep.c (single_step): Don't call ptrace ourselves, just
2542 set up to be ready to continue. This makes us target independent.
2543 * infptrace.c (child_resume): Remove call to single_step; now
2544 can single step a SPARC target of any kind.
2546 Wed May 22 18:18:24 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
2548 * Makefile.dist, doc/gdb.texinfo, doc/*-m4.texinfo: split up GDB
2549 docn into separate sections---basically chapters, plus two loose
2550 pieces that can be configured to go in different places. This
2551 allows GNU m4 to preprocess the manual without coredumping.
2553 * Makefile.dist: tell TeX where to find texinfo.
2555 Mon May 20 12:15:04 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
2557 * Makefile.dist, doc/gdb.texinfo: respectively create, and use,
2558 the new target "rdl-apps.texinfo" which captures the Makefile
2559 variable that records where to find the Readline libraries.
2561 Sun May 19 05:36:59 1991 John Gilmore (gnu at cygint.cygnus.com)
2563 * tahoe-pinsn.c: #include "tahoe-opcode.h", not "opcode.h".
2564 * tm-tahoe.h (FIX_CALL_DUMMY): Ignore more parameters.
2565 * defs.h (const, volatile): Only define if not already defined.
2566 * Makefile.dist (gdb.tar.Z): Create doc subdir w/out CVS/RCS crud.
2568 * README: Update for release 3.95.
2569 * config.gdb: Don't create readline dir in subdir builds.
2570 * main.c: Include with "..." form for non-system include files,
2571 so "gcc -MM" for "make depend" works.
2572 Include readline files with "...h" rather than <readline/...h>.
2573 * mipsread.c: Include "ecoff.h" rather than "intel-coff.h".
2575 * coffread.c: Undo minor damage done by Rich Pixley. Use
2576 different internal and external representations of COFF
2577 data structures. Use new BFD routines for swapping them in and
2579 * symfile.c (free_named_symtabs): Avoid freeing file names that
2580 are null or empty. Old i960 tools seem to produce files that
2581 claim to have empty names, causing each successive file read
2582 to blow away the previous one.
2583 * sparc-xdep.c (deferred_stores): Repair minor damage by Rich.
2584 Move deferred_stores to top of file, but don't separate its
2585 #define's from its variable. Add commentary.
2586 * Makefile.dist: Fix Rich damage; undo "configure" changes in
2587 favor of keeping the (working) config.gdb. Move readline
2590 Fri May 17 12:49:56 1991 Per Bothner (via gnu at cygint.cygnus.com)
2592 * dbxread.c (read_struct_type): Try to handle g++ version 1 MI
2594 * infptrace.c (fetch_registers): no result, since now void.
2595 * tconfig/news: target depends on m68k-tdep too.
2597 Fri May 17 14:40:14 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
2599 * Makefile.dist: added readline/inc-*.texinfo to dependencies for
2602 * readline/inc-history.texinfo, readline/inc-readline.texinfo:
2603 applied various small fixes due to or inspired by RMS comments
2605 * doc/gdb.texinfo: finished using all RMS comments, save those for
2606 appendices on readline and cmd history (which are in other source
2609 Thu May 16 18:06:05 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
2611 * doc/gdb.texinfo: (1) Updated w/ref to RMS comments through
2612 chapter 9; (2) documented 'break' command's menu mode for
2613 overloaded names, in response to hgs problem report C++ p-31
2615 Wed May 15 11:02:48 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
2617 * doc/gdb.texinfo: (1) better introductory example; (2) more
2618 consistent use of @code, @samp, @file, @kbd throughout; small
2619 cleanups to first three nodes; (3) new "Contributors" node;
2620 (4) Appendix, Renamed Commands; (5) divert specialized startup
2621 instructions to "Targets" chapter for generic manuals, while
2622 leaving them up front for manuals specific to specialized
2623 environments; (6) apply fixes from RMS comments through chapter 4.
2625 * pretex.m4: modify explanatory text slightly (and redefine
2626 "regexp") to keep GNU m4 from complaining. (It still crashes
2627 later, but one step at a time...)
2629 Wed May 15 10:32:12 1991 John Gilmore (gnu at cygint.cygnus.com)
2631 * readline/readline.c (update_line): Avoid dereferencing a pointer
2632 before comparing it to its bounds. Saber caught this.
2633 (init_terminal_io): Don't set BC from the "pc=" termcap variable,
2634 and only set PC if tgetstr returned non-null. Saber caught this.
2636 Tue May 14 16:29:53 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)
2638 * Makefile.dist: put gdb.dvi stuff (updated to use M4 preprocessor
2639 stuff for config manual) here where it counts; updated
2640 to use new subdir structure (gdb/doc/).
2642 * Makefile: generated from above via
2646 * gdbint.texinfo: added instructions on generating gdb.info* files
2647 locally for release. These are ordinary info
2648 files, formatted from gdb.texinfo (via gdb-all.texinfo, see
2649 Makefile)---but due to use of texinfo 2, can't count on makeinfo
2650 to generate these, so we distribute them already formatted.
2652 * gdb.texinfo: included full Info node and menu crud (as generated
2653 by C-u M-x texinfo-master-menu using the texinfo-2 elisp code).
2655 * Makefile: updated "gdb.dvi" target to use M4 preprocessor;
2656 put in comments-for-future gdb.info target (one day makeinfo will
2659 Tue May 14 13:51:36 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)
2661 * gdb.texinfo: Updated to include new or old undocumented
2662 commands, at least the following (perhaps some others I forgot to
2663 record): info f, info float, info path, info program, info s, info
2664 set, info source, info terminal, info types, info user, set/show
2666 Also covered all recent GDB command renames for v4.
2668 Mon May 13 14:57:46 1991 John Gilmore (gnu at cygint.cygnus.com)
2670 * mipsread.c: Rather than keeping count of how many symtabs
2671 and psymtabs we have, for sorting purposes, count them when
2672 we need to sort. This fixes bug in rereading of symbol tables.
2674 Fri May 10 15:43:33 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)
2676 * infcmd.c: renamed "info path" to "show paths"

2687 Fix up "saber_gdb" to work again.
2688 * saber.suppress: Update.
2690 * coffread.c, exec.c, infptrace.c, inftarg.c, remote.c, solib.c,
2691 symtab.h, target.c, target.h: Lint.
2692 * core.c: setup and select frame after reading shared libs,
2693 else reading shared libs will clobber them. Lint.
2694 * utils.c (error): Force out any buffered wrap text.
2696 Fri May 3 22:01:56 1991 John Gilmore (gnu at cygint.cygnus.com)
2698 * remote.c: Remove decls of memory_insert_breakpoint
2699 and memory_remove_breakpoint, no longer used. (Suggestion of
2702 * Makefile.dist: use ${subdir} in paths of BFD and LIBIBERTY,
2703 to make it easier to interface to "configure"'d libraries.
2705 Fri May 3 13:10:01 PDT 1991 Roland Pesch (pesch at fowanton.cygnus.com)
2707 * valprint.c: introduce "set p", "set pr", "show p" and "show pr" as
2708 aliases for set/show print.
2710 Thu May 2 11:22:02 1991 Jim Kingdon (kingdon at cygint.cygnus.com)

2760 dc_dcontext_t not int.
2762 * coffread.c [TDESC]: Use system include files not <intel-coff.h>.
2764 * coffread.c [TDESC]: Move setting of debug_info from
2765 coff_symfile_read to find_linenos and make it work with BFD.
2767 * cplus-dem.c [__STDC__]: Make x{m,re}alloc return void*.
2769 * signame.c: Cast const char* to char* when assigning to sys_siglist.
2771 * utils.c (strsave): Make arg const char* not char*.
2773 * infrun.c (wait_for_inferior) [SHIFT_INSN_REGS]: Use

2792 Thu May 2 17:53:56 1991 John Gilmore (gnu at cygint.cygnus.com)
2794 Mips bringup and general cleanup
2796 * cplus-dem.c: Move CPLUS_MARKER define to after defs.h.
2797 * infptrace.c (PT_WRITE_D, PT_READ_D): Use correct values.
2798 (This still doesn't seem to make MIPS bkpts work.)
2799 * mipsread.c: Remove dup "Reading symbol data..." msg.
2800 (symbol_file_command, add_file_command): Remove, obsol.
2801 * printcmd.c (ptype_command): Say "an enum" rather than "a enum".
2802 Wrap output appropriately.
2803 * stack.c (locals_info, catch_info, args_info): Check
2804 selected_frame rather than target_has_stack or coredumping.
2805 * valprint.c (type_print_varspec_suffix): Wrap "ptype" output of
2806 enums appropriately.
2808 Wed May 1 14:10:22 1991 Jim Kingdon (kingdon at cygint.cygnus.com)
2810 * signame.c: Include defs.h and param.h.
2812 * cplus-dem.c: Include defs.h and param.h.
2813 Makefile.dist: Don't hack in the "param.h".
2814 param.h: Don't include defs.h.

2817 can have both ints and enum type_pieces in it.
2818 ({push,pop}_type_int): New functions.
2820 Tue Apr 30 13:18:58 1991 Jim Kingdon (kingdon at cygint.cygnus.com)

2832 symtab.c, cplus-dem.c, value.h, expread.y, valprint.c,
2833 copying.awk, solib.c, inflow.c, symmisc.c
2834 : Lint. Use read_memory not read_memory_integer on CORE_ADDR's.
2835 Use {value_as,unpack}_pointer (added to values.c)
2836 not {value_as,unpack}_long on CORE_ADDR's.
2837 Use longest_to_int (added to defs.h) instead of cast to int.
2838 Remove from_tty arg to mod_path.
2839 Put symfile_bfd in {coff,dbx}read.c not symfile.h.
2840 Use OP_NULL instead of 0 where dummy enum exp_opcode needed.

2881 Sun Apr 28 22:04:47 1991 Jim Kingdon (kingdon at cygint.cygnus.com)
2883 * param-no-tm.h: Make BITS_BIG_ENDIAN defined to 0/1, not defined
2884 or not defined. Don't define it based on TARGET_BYTE_ORDER if

2886 mips-opcode.h (BIT_FIELDS_*),
2887 values.c (modify_field, unpack_field_as_long):
2888 Use #if BITS_BIG_ENDIAN not #ifdef BITS_BIG_ENDIAN.
2889 {x,t}m-tahoe.h, tahoe-pinsn.c, tahoe-opcode.h: New files.
2891 Fri Apr 26 12:02:06 1991 Jim Kingdon (kingdon at cygint.cygnus.com)
2893 * tm-sparc.h: Add comments about gcc version 2 and structure passing.

3313 (set_section_command): New command ("section xxx yyy" -- should
3314 be renamed to "set section xxx yyy" FIXME) which sets the

3328 * i386-pinsn.c: Move #includes to top, remove useless ones.
3329 * i386-tdep.c: Don't bother including <.../reg.h> since we

3346 current frame in the core file, if we have one.

3366 * Makefile.dist, README, config.gdb, convex-pinsn.c,
3367 tconfig/symmetry, tconfig/vxworks960, tconfig/vxworks68,
3368 xconfig/hp300hpux, xconfig/symmetry: Change names to shorter
3371 * command.c (user_info_1, user_info): New command for listing
3372 the user-defined commands.
3374 Wed Apr 3 15:00:26 1991 John Gilmore (gnu at cygint.cygnus.com)
3376 * dbxread.c (really_free_pendings): Clear file_symbols
3377 and global_symbols after freeing them; otherwise, running
3378 this function twice (if it appears twice on the cleanup
3379 chain), we try to free things twice.
3381 * dbxread.c (read_dbx_symtab): Calculate end_of_text_addr
3382 based on text_addr (the address of text in core), not on addr (the
3383 offset between text in the .o file and in core). This change
3384 is from Peter Schauer.
3386 * main.c: Define ALL_CLEANUPS as a cast of zero.
3387 (return_to_top_level): Use it.
3388 (main): Do all cleanups after each command run as part
3389 of the gdb startup sequence. Also do all cleanups before
3390 entering the command loop, and every time we exit the command
3391 loop and reenter. Before, the cleanups from the startup sequence
3392 were being left undone until the first error!
3393 (command_loop): Rename do_nothing cleanup to command_loop_marker
3394 so we can see it easily when examining the cleanup chain.
3395 (init_signals): Add another do_nothing for signal handling.
3396 (quit_command): Only try to kill target if it has execution.
3397 Problems in the target stack got us into a state where
3398 inferior_pid was nonzero but none of the targets had execution.
3399 In this state you couldn't exit gdb.
3401 * dbxread.c: Two changes from Peter Schauer.
3402 (echo_command): Fflush output after an echo command.
3403 (show_history): Pass all args to cmd_show_list.
3405 * utils.c (init_malloc): Call mtrace to turn on tracing
3406 if the environment variable MALLOC_TRACE is set to a file name.
3407 * mtrace.c: Add source file which provides a log of every malloc,
3408 free, and realloc to a trace file.
3409 * mtrace.awk: Add source file which analyzes the trace file.
3410 * Makefile.dist (GNU_MALLOC, MALLOCSRC): Add mtrace.{c,o,awk}.
3411 (VERSION): Roll to 3.94.3.
3413 * breakpoint.c (breakpoint_1): Add a space to "i watch" output.
3414 (check_duplicates): Don't bother with watchpoints.
3415 (set_raw_breakpoint): Comment about danger of this routine.
3416 (watch_command): Parse and eval all args before calling
3419 * solib.c (find_solib): Avoid error in referencing memory to
3420 see if any more shared libraries have been added. This is
3421 particularly useful if the target has terminated. Bug reported
3424 Changes from Peter Schauer <pesrem@regent.e-technik.tu-muenchen.de>
3425 in bringing up 3.94.2 on the Sun-3.
3427 * Makefile.dist: Include CFLAGS in rule for cplus-dem.o.
3428 * breakpoint.c (enable_breakpoint): Check for valid watchpoint
3429 expression (in scope) before reenabling watchpoint.
3430 * signame.c (init_sigs): Add missing declaration of i, fix
3431 sys_siglist declaration.
3432 * source.c (list_command): Fixed range computation to use
3434 * stack.c (backtrace_command): Do not allow command if target has
3435 no stack, print informative error message.
3436 * target.c (target_command): Do not write into command line
3437 because this fails if the target command is used in a user defined
3438 command. [This change was enhanced by gnu to support any-
3439 unique-prefix matching on target names.]
3440 * valops.c (value_struct_elt): Avoid infinite loop on an
3441 erroneous attempt to print the member of function (try p main.p).
3443 Mon Apr 1 17:05:45 1991 John Gilmore (gnu at cygint.cygnus.com)
3445 * expread.y (name_no_typename): Avoid reduce/reduce errors
3446 caused by ambiguity in handling NAME_OR_INT and NAME_OR_UINT.
3447 Since the GDB parser really doesn't use name_no_typename in a
3448 name-only context, the parser can't tell the diff between
3449 names and numbers here. Avoid allowing a name_no_typename
3450 to be a NAME_OR_*INT to resolve the conflict.
3452 Sun Mar 31 20:12:07 1991 John Gilmore (gnu at cygint.cygnus.com)
3454 Bugfixes from Mark Fox (markf@wrs.com) (test=testField.c):
3456 * valprint.c (val_print_fields): bitfield printing didn't handle
3457 byte order. Indirect through a few more fns to cope.
3459 * values.c (modify_field): also cope with byte order.
3461 Sat Mar 23 10:02:21 1991 John Gilmore (gnu at cygint.cygnus.com)
3463 Cleanup for release 3.94.2:
3465 * Makefile.dist: Pull REMOTE_OBS. Fix saber includes for BFD
3466 include files. Roll version to 3.94.2.
3468 * coffread.c (init_stringtab): Read length into unsigned char
3469 array before swapping; don't assume 32-bit longs.
3471 * target.c (target_info): Don't bother with get_sym_file, just use
3472 the symfile global variable.
3473 * symtab.h, symfile.c (get_sym_file): Delete it.
3475 * dbxread.c (dbx_symfile_init): Don't depend on long == 4 bytes.
3476 (define_symbol): Set symbol line number to 0 if not gcc-compiled.
3477 (read_type): Replace one more error() with complain().
3479 * mipsread.c (parse_partial_symbols): Replace printf with complain.
3481 * i960-tdep.c: Fix copyright attribution.
3483 * config.gdb: Quote all backquotes in doublequotes. You can
3484 quote me on that. BSD 4.4 shell found this one.
3486 * infptrace.c (throughout): The third argument to ptrace is an
3489 * infrun.c (wait_for_inferior): When program has terminated, we
3490 have to call target_terminal_ours before we pop that target off
3491 the stack (e.g. before a call to target_kill or
3492 target_mourn_inferior). This fixes problem where a program
3493 terminates, then GDB stops for (tty output) and you have to type
3494 "fg" to the shell to resume it. FIXME: This code for what to
3495 do after termination really should be in normal_stop instead.
3497 * gdbcore.h (read_memory_check): Change declaration; it changed
3500 * terminal.h: Include <sgtty.h> before <sys/ioctl.h>, since in BSD
3501 4.4 prereleases, this avoids a bug in their sgtty compatability
3503 * remote.c: Use terminal.h rather than hand-rolling the same.
3505 * signame.c, signame.h (psignal): Arg is unsigned, not int.
3506 * utils.c (strsave, strstr): Fix arg types.
3507 * valprint.c (val_print): lint
3509 MIPS symbol table support from Per Bothner:
3511 * symfile.c (symtab_fns): Remove initializer table that needs to
3512 be hacked for each new symbol file format supported.
3513 (add_symtab_fns): New function, chains symbol table
3514 handlers into the global list.
3515 (symfile_init): Search this list.
3516 * symfile.h: Add next pointer, declare add_symtab_fns.
3517 * coffread.c (_initialize_coffread): Call add_symtab_fns.
3518 * dbxread.c (_initialize_dbxread): Call add_symtab_fns.
3520 * mipsread.c (psymtab_to_symtab_1): return void instead of (struct
3521 symbol *). Thus, we no longer need the hack to trash
3522 pst->filename. Good, since that hack confused code in symfile.c!
3524 (reorder_symtabs, destroy_all_symtabs): Removed static
3525 all_symtabs, which was used to qsort symtabs in reorder_symtabs.
3526 Instead, the latter now uses a temporary array (stack-allocated
3527 from an obstack, and then freed).
3529 (parse_symbol): Added a hack to fix up BLOCK_{START,END} if they
3530 haven't been set in the outermost stBlock of a procedure. This was
3531 a problem with f77 binaries on Ultrix 4.?.
3533 (new_symtab, new_symbol, new_type): Continue changing code to use
3534 obstacks more and otherwise conform to dbxread internal style.
3535 Made the free_code of symtabs be free_linetable (as in dbxread)
3536 instead of free_contents. This implies memory leaks when reading
3537 a new symbol table, until the conversion is finished. Did change
3538 (struct symbol) and (struct type) to be allocated on the
3539 symbol_obstack. Blocks and blockvectors are among the things
3542 * mipsread.c (parse_partial_symbols, parse_fdr): It hasn't been
3543 tested much, but it solved one problem (reported by Meissner), and
3544 cleans up some other things. The problem happened when an
3545 included file contains actual code (functions) and not just
3546 definitions. The mips coff is a little inconvenient there, since
3547 it may cause a procedure to be mapped to the wrong psymtab.
3549 * mips-tdep.c (heuristic_proc_desc): Minor cleanup.
3550 * mips-xdep.c (fetch_core_registers): Minor cleanup. FIXME,
3551 this will need work for the new core paradigm.
3553 Opcode patches from the net:
3555 * mips-opcode.h: fix incorrect disassembly of the mfc1, cfc1, and
3556 ctc1 instructions. Also, the cvt.d.w and cvt.s.w instructions were
3557 missing altogether - they are added here. From Bruce Bauman.
3558 * mips-opcode.h: The low mask for C0 instructions was too small.
3559 From Garrett Lau. I modified the fix to check the entire 32-bit
3562 * ns32k-opcode.h: Fix opcodes for deiw and deid. From Bruce
3565 Thu Mar 21 12:56:46 1991 John Gilmore (gnu at cygint.cygnus.com)
3567 Roll in changes from Per Bothner (Tue, 25 Sep 90 11:11:04):
3569 * dbxread.c (read_type): Pointer subtraction (value_sub in
3570 valarith.c) sometimes failed because the types of the
3571 pointers being subtracted were not identical.
3572 These differed because dbxread.c was allocating pointer types
3573 using dbx_alloc_type+smash_to_pointer_type instead of
3574 lookup_pointer_type. I failed to find a justification for the
3575 former, so I changed it to use the latter. Similarly, I
3576 replaced smash_to_function_type by lookup_function_type,
3577 and smash_to_reference_type by lookup_reference_type.
3579 * mipsread.c (parse_symbol, upgrade_type, parse_procedure,
3580 _initialize_mipsread): corresponding changes.
3582 * symtab.c (smash_to_{pointer,reference,function}_type): eliminate.
3584 * source.c (mod_path): Do tilde_expand on each component of the path,
3585 rather than on the (list of) paths as a whole.
3586 (print_source_lines): Set first_line_listed in addition to
3587 current_source_symtab and current_source_line. If the source was
3588 not findable, after a "dir" command to fix the problem,
3589 a "list" would get the wrong lines.
3591 While I was there... (gnu):
3593 * dbxread.c (read_type): Change error to complaint.
3595 Thu Mar 21 12:56:46 1991 John Gilmore (gnu at cygint.cygnus.com)
3597 First attempt at detailed understanding of symbol table memory alloc.
3599 * dbxread.c (dbx_symfile_read): Free our string table if we
3600 aren't the mainline. Free the "info" struct since we're done with
3602 (init_psymbol_list): Free any previously allocated psymbol lists.
3603 (): FIXME: Should realloc-down the psymbol lists when done reading
3604 the main symbol file?
3606 * symmisc.c (free_symtab): Free fullname field too.
3608 * xm-hp300hpux.h (USG): #undef then #define so Makefile can -D.
3609 (REGISTER_ADDR): Make result type unsigned int.
3611 * xconfig/{i386*,hp300hpux,altosgas,altos}: All config files that
3612 define REGEX must also define REGEX1 (its dependency).
3614 Tue Mar 19 21:28:57 1991 John Gilmore (gnu at cygint.cygnus.com)
3616 * tconfig/i960: No longer works, points you at vxworks960 or
3619 * xgdb.c, XGDB-README: Remove file. Users can get the much
3621 * Makefile.dist: Remove all trace of xgdb.
3623 * breakpoint.c (breakpoint_1): Pass demangle arg to
3624 print_address_symbolic.
3625 (clear_breakpoints): Remove unused function.
3626 (breakpoint_re_set_one): Guts of breakpoint_re_set.
3627 (breakpoint_re_set): Use catch_errors to do them all anyway.
3629 * gdb-int.texinfo (Host versus Target): Add section on what is
3630 a "host" feature versus what is a "target" feature.
3632 * infcmd.c (path_command, path_info): Handle the PATH variable
3633 (object search path) as conveniently as the source search path.
3634 * environ.c (set_in_environ): Set some vars in GDB's environment,
3635 in addition to the child's. PATH, G960BASE, G960BIN for starters.
3636 * source.c (mod_path): New function, from guts of
3637 directory_command, modifies a path. Used by path_command.
3638 (directory_command): Call it.
3639 * defs.h (strsave): Declare.
3641 * utils.c (sevenbit_strings): Add new printing option.
3642 (printchar): Use it.
3643 (strsave): Provide this handy helper routine.
3644 (set_width_command): Rename set_screen_width_command.
3645 (_initialize_utils): "set screen-width" => "set width";
3646 "set screen-height" => "set height"; add sevenbit-strings.
3648 * infcmd.c (do_registers_info): Print floating point registers
3649 in raw hex as well as float format, regardless of whether it is
3650 a "virtual" convertible register.
3651 * tm-sparc.h (PRINT_REGISTER_HOOK): Print every pair of float
3652 regs as a double, just in case it's being used that way.
3653 * values.c (unpack_long): Comment on array/function coercion.
3654 (unpack_double): Argument is in target byte order now. For
3655 integer arguments, just call unpack_long and float the result.
3656 * m68k-tdep.c: include defs.h for "const" handling.
3657 * remote-nindy.c: Use ieee-float stuff.
3658 (nindy_fetch_registers): Unpack double regs to host double, then
3660 (nindy_store_registers): Pack extendeds to host double, flip
3661 around by misusing unpack_double, send as target double.
3663 * tm-vxworks68.h (FRAME_CHAIN): Handle current frame pointer of
3664 zero, as when stopped at the first instruction of a process.
3666 * blockframe.c: Fix filename in comment (param.h => tm.h).
3667 * sparc-tdep.c (skip_prologue): More explicit nudging comments.
3668 * tm-68k.h: Fix typos.
3670 Fri Mar 15 01:09:34 1991 John Gilmore (gnu at cygint.cygnus.com)
3672 Changes from a bringup on the DEC Vax under Ultrix 4.0.
3674 * coredep.c (fetch_core_registers): Pass end-address of register
3675 section to register_addr as expected. Don't call supply_register
3676 if we'd just pass it garbage.
3678 * dbxread.c (read_dbx_symtab): Skip N_NSYMS on Ultrix.
3680 * exec.c (xfer_memory): Use boolean xfer_fn result, not int.
3682 * target.c (push_target, target_info): Cast enums to int for < or
3685 * stack.c (print_frame_info): Identify source file & line
3686 even if we can't print it.
3688 * xm-vax.h (MISSING_VPRINTF): No longer missing in Ultrix V4.0.
3690 Sat Mar 9 10:08:20 1991 John Gilmore (gnu at cygint.cygnus.com)
3692 Clean up IEEE floating point support.
3694 * ieee-float.h: New file.
3695 * ieee-float.c: Write real routines to convert between host
3696 doubles and various target IEEE extendeds.
3697 * m68k-xdep.c: Eliminate assembler code for extended floats.
3698 * xconfig/{3b1,altos,altosgas,hp300bsd,isi,news,news1000,sun2os3,
3699 sun2os4,sun3,sun3os3,sun3os4}: Eliminate use of m68k-xdep.o.
3700 * tm-i960.h, tm-68k.h (REGISTER_CONVERT_TO_VIRTUAL,
3701 REGISTER_CONVERT_TO_RAW): Use ieee_extended_to_double and
3702 double_to_ieee_extended.
3703 * i960-tdep.c: Define ext_format_i960.
3704 * m68k-tdep.c: Define ext_format_68881.
3705 * sparc-tdep.c: Define ext_format_sparc, though unused.
3706 * Makefile.dist (HFILES): Add ieee-float.h.
3707 * inftarg.c: #include "ieee-float.h" for the REGISTER_CONVERT
3710 Obsolete the "coffstrip" program in favor of using BFD's strip.
3712 * nindy-share/coffstrip.c: Remove file.
3713 * nindy-share/nindy.c (coffstrip): Routine to run bfd_strip.
3714 * Makefile.dist: Remove references to nindy-share/coffstrip.c.
3715 * tconfig/nindy960: Remove reference to coffstrip.o.
3717 * Makefile.dist: Roll version number to 3.94.1 (not yet final).
3719 Wed Mar 6 09:56:45 1991 John Gilmore (gnu at cygint.cygnus.com)
3721 * symfile.h: Add symfile_bfd, common between dbxread and coffread.
3722 * dbxread.c: Remove static symfile_bfd.
3723 * infcmd.c (do_registers_info): Add PRINT_REGISTER_HOOK, though
3725 * inftarg.c (child_detach): Pop the child_ops vector if the
3726 detach is successful.
3727 * remote-nindy.c (nindy_create_inferior): Don't push a new
3728 nindy_ops since nindy uses the same one for execution and memory
3730 * core.c (core_ops): Use child_attach and child_create_inferior
3731 rather than default attach and create_inferior functions.
3733 Handle floating point registers in core files.
3735 * sparc-xdep.c (fetch_core_registers): Rewrite for float support.
3736 * sun3-xdep.c (fetch_core_registers): Rewrite for float support.
3737 This version untested since BFD doesn't yet support sun3 core
3739 * hp300hpux-xdep.c: Rewrite fetch_core_registers to new calling
3740 conventions. Fix comments and style. This version has not
3741 been compiled yet, since we have no HP inhouse.
3742 * core.c (get_core_registers): Look for two sections, ".reg"
3743 and ".reg2", and pass both to fetch_core_registers sequentially.
3745 Revise directory path yet again.
3747 * source.c (forget_cached_source_info): Not static any more.
3748 (init_source_path): New default source path is "$cdir:$cwd".
3749 (dir_command): Handle variable arguments ($cdir, $cwd).
3750 (source_info): Print "Compilation directory" rather than
3751 "Originally compiled in" to remind people of $cdir.
3752 (openp): If the path contains $cwd, use current directory.
3753 (open_source_file): If compilation directory is known, replace
3754 first $cdir in path with the compilation directory.
3755 (print_source_lines): Even if we can't print the lines, set the
3756 current symtab and line for future commands like "info source" or
3757 "breakpoint". Also, error message now contains the file name,
3758 line number, and file access error message.
3759 (_initialize_source): Fix help text to describe changes.
3760 * main.c (cd_command): Forget cached source info when we chdir.
3761 * utils.c (strstr): Add simple implementation.
3763 Tue Mar 5 01:41:40 1991 John Gilmore (gnu at fowanton.cygnus.com)
3765 * coffread.c (read_one_sym, init_linetable, init_stringtab):
3766 Byte-swap COFF symbol tables if necessary when reading them in.
3767 Use complain() to replace error message in one spot. Needs
3768 corresponding change in bfd/coff-code.h to make some symbol
3769 swapping routines non-static.
3771 Mon Mar 4 00:53:40 1991 John Gilmore (gnu at cygint.cygnus.com)
3773 Merge changes from Eirik Fuller, for UTek.
3775 * defs.h (errno): Add declaration.
3776 * altos-xdep.c, arm-xdep.c, convex-xdep.c, gould-xdep.c,
3777 hp300hpux-xdep.c, infrun.c, inflow.c, infptrace.c, i386-tdep.c,
3778 i386-xdep.c, pyr-xdep.c, mips-xdep.c, remote-eb.c, remote-nindy.c,
3779 remote-vx.c, source.c, standalone.c, stuff.c, sun386-xdep.c,
3780 symmetry-tdep.c, symmetry-xdep.c, umax-xdep.c, utils.c: Eliminate
3781 declarations of errno.
3783 * remote-eb.c: Define B19200 and B38400 as EXTA and EXTB.
3785 * remote-vx.c: Include <sys/time.h> for UTek; Sun gets it via
3786 <rpc/rpc.h> and <rpc/types.h>.
3788 Sat Mar 2 15:47:55 1991 John Gilmore (gnu at cygint.cygnus.com)
3790 * i960-tdep.c (examine_prologue): Add new argument limit,
3791 which stops the scan at the end of the prologue, or at the PC.
3792 This fixes a problem where it walks down into the code for the
3793 user's statements if that code looks like function prologues.
3794 Mark Fox and I have been bouncing this code back and forth, making
3795 small changes to it. Callers changed to match.
3797 Tue Feb 26 01:47:07 1991 Cygnus John Gilmore (cygnus at yuba)
3799 Cleanup for gdb-3.94 release final:
3801 * Makefile.dist: Remove remote-vx.c, remote-nindy.c, and all
3802 the .c files from vx-share and nindy-share, from the various
3803 macros, since they are not found via ALLDEPFILES.
3804 (SFILES): Add tm-i960.h.
3805 (alldeps.mak rule): Break out ALLDEPFILES_MAINDIR and
3806 ALLDEPFILES_SUBDIR. List all the nindy and vxworks subdir files
3808 (TAGFILES_MAINDIR): Change ALLDEPFILES to ALLDEPFILES_MAINDIR.
3809 (gdb.tar.Z): Use ALLDEPFILES_SUBDIR as well as SFILES_SUBDIR.
3811 Mon Feb 25 16:02:35 1991 Cygnus John Gilmore (cygnus at oldman)
3813 * am29k-tdep.c: Add contribution line.
3814 (examine_prologue): Cache information about function prologues in
3815 the misc-function-vector to avoid lots of references over the
3816 serial line while examining instructions.
3818 * core.c (core_close): New function made from cleanup_core.
3820 * core.c, exec.c, inftarg.c, remote-eb.c, remote-nindy.c,
3821 remote-vx.c, remote.c, target.c, target.h,
3822 Update target_ops vector to add attach, close, and load entries.
3823 Use add_syms_addr_command, not add_file_addr_command, for
3824 add_file. Break out close routine from existing code.
3826 * dbxread.c (really_free_pendings): Don't free pending_blocks;
3827 they are in an obstack.
3828 (read_dbx_symtab): Relocate end_of_text_addr in the psymtab.
3830 (define_symbol): Add symbol type parameter; change callers;
3831 pass type parameter to DBX_PARM_SYMBOL_CLASS macro to allow
3832 it to influence the symbol class on the i960.
3833 (define_symbol): Swap LOC_CONST's into target byte order.
3835 * exec.c (exec_close): New function.
3836 (exec_file_command): Call it.
3838 * findvar.c (read_relative_register_raw_bytes): Doc byte order,
3839 Fix byte order of frame pointer.
3840 (read_var_value): Result of 0 if var's value can't be found,
3841 e.g. missing FRAME_ARGS_ADDRESS. Byte-swap LOC_CONST and
3842 LOC_LABEL values to target order. Add LOC_LOCAL_ARG.
3843 (locate_var_value): Use read_var_value and use its lazy address
3844 as the location of the var's value. Lint.
3846 * i960-pinsn.c (next_insn): Add routine from vxgdb for scanning
3849 * i960-tdep.c (arg_address, i960_frame_find_saved_regs): Remove
3850 obsolete Intel versions in favor of vxgdb versions.
3851 (check_host, byteswap, byteswap_val, reorder_val): Eliminate
3852 code dealing with byte order of values, which Intel did in host byte
3853 order rather than gdb-4's target byte order.
3854 (i960_frame_chain_valid): Move to nindy-tdep.c.
3855 (examine_prologue, skip_prologue, frame_find_saved_regs,
3856 frame_args_address, leafproc_return, saved_pc_after_call,
3857 pop_frame): Add vxgdb versions from Mark Fox.
3858 (examine_prologue, frame_struct_result_address): Add code
3859 to deal with the saved value of G13 (struct return address
3861 (frame_args_address): Modify Mark's version to prefer the
3862 saved value over the current value in the topmost frame.
3863 Cache result in the frame info to avoid performance hair in
3865 (print_fault): Add gdb960 code for printing faults.
3866 (_initialize_i960): Actually call check_host.
3868 * ieee-float.c (ieee_extended_to_double, ieee_double_to_extended):
3869 add stub routines. FIXME, these currently just return zero!
3871 * infcmd.c (program_info): Use PRINT_RANDOM_SIGNAL.
3872 (attach_command): Call target_attach, not target_open, now.
3874 * infrun.c (normal_stop): Make global, not static, for vx_attach.
3875 (child_attach): Rename from child_open.
3876 (wait_for_inferior): Use PRINT_RANDOM_SIGNAL. If stop_pc is zero,
3877 don't confuse it with a zero step_resume_break_address.
3879 * inftarg.c (child_detach): Eliminate inferior_pid test.
3880 (child_files_info): Clean up message a bit.
3881 (child_ops): Use child_attach, not child_open, to attach.
3883 * mem-break.c: #ifdef out the whole file if BREAKPOINT is not
3884 set (e.g. on VxWorks or NINDY). Move read_memory_nobpt from
3885 findvar.c to here, since it depends on the contents of the
3886 shadow_contents of breakpoints, but keep if #if 0 since it is
3889 * nindy-tdep.c: New file, contains nindy_frame_chain_valid, moved
3892 * printcmd.c (address_info): Handle LOC_LOCAL_ARG. Lint.
3893 (ptype_command, display_command): Eliminate have_inferior_p and
3894 have_core_file_p in favor of target_has_stack or
3895 target_has_execution.
3896 (print_frame_args): Handle LOC_LOCAL_ARG. Eliminate duplicate
3897 code for actually finding the values of arguments, though we still
3898 keep track of the maximum stack offset for use in printing unnamed
3899 arguments. Handle missing FRAME_ARGS_ADDRESS.
3901 * remote-nindy.c (i960_print_fault): Move to i960-tdep.c.
3902 (struct nindy_regs): Define registers passed to/from nindy.
3903 (nindy_fetch_registers, nindy_store-registers): Translate between
3904 nindy and GDB formats for the registers.
3905 (dcache_init): Statically allocate the cache, since it was being
3906 allocated by a malloc that was never freed anyway.
3907 (nindy_create_inferior): Error, not core dump, if no exec file.
3908 (nindy_before_main_loop): Use target_load, not target_add_file.
3910 * remote-vx.c (net_load): Specify large timeout for load
3911 requests. Allow user to break out with INTERRUPT.
3912 (net_break): Remove useless code, clean up. Change callers.
3913 (parse-args, skip_white_space, find_white_space): Clean up arg
3914 parsing to cope with quoted strings.
3915 (net_wait, net_quit): Never call error, just return status.
3916 (vx_read_register, vx_write_register): Cleanup status checking.
3917 #ifdef the code based on which CPU we are using (960 or 68k),
3918 FIXME, this should be completely general but it isn't yet.
3919 (vx_xfer_memory, vx_resume): Cleanup status checking.
3920 (vx_run_files_info): Improve message.
3921 (vx_load_command): Renamed from vx_add_file_command. Allow load
3923 (net_ptrace): Remove unused routine.
3924 (vx_wait): Adopt code from vxgdb960 to cope with broken
3925 connections to target machine and prompt to disconnect. Remove
3926 debug printouts. Map some EVENT_'s to SIGnals.
3927 (add_symbol_stub, vx_open): Print names of object files we found,
3928 and "ok" if we read their symbols OK. Clarify output in general.
3929 (vx_attach, vx_detach, vx_kill): Add these commands.
3930 (vx_convert_from_virtual, vx_convert_to_virtual): Simplify.
3931 (vx_run_ops): Turn off all_mem, to avoid spurious msg in the
3932 "info files" output, and create_inferior, since we already have
3935 * stack.c (frame_info): Replace Frame_unknown with 0.
3936 (print_frame_arg_vars): Handle LOC_LOCAL_ARG.
3937 (return_command): Pop until the PC matches as well as the FP,
3938 so it works even if the FP is shared with another function,
3939 as in "frameless" or "leaf" procedures.
3941 * symfile.c (load_command): renamed from add_file_target_command.
3942 (add_syms_addr_command): renamed from add_file_addr_command.
3943 (add_syms_command): Stub to call target_add_syms.
3944 (_initialize_symfile): Change command names and descriptions,
3945 add-file => add-syms, and load from alias to its own command.
3947 * target.c (kill_or_be_killed, maybe_kill_then_attach,
3948 maybe_kill_then_create_inferior): Default for attempts to start
3949 a process, if one is already running, is to ask about killing
3950 it and retry if yes.
3951 (upstack_create_inferior): #if-0 it, strata obsolete it.
3952 (push_target, unpush_target, pop_target): to_close() a target
3953 before unstacking it.
3954 (target_info): Renamed from target_files_info.
3955 (_initialize_targets): Rename "i files" as "i target", accessible
3958 * target.h: Improve comments about the target_ vectored routines.
3960 * tm-i960.h: Remove NINDY-specific stuff to tm-nindy960.h.
3961 Convert commenting style to standard GNU style.
3962 (DBX_PARM_SYMBOL_CLASS): allow LOC_LOCAL_ARG's to be recognized.
3963 (SKIP_PROLOGUE): No longer a no-op.
3964 (SAVED_PC_AFTER_CALL): Now handles leaf procedures.
3965 (*_REGNUM): Sort register numbers.
3966 (REGISTER_BYTES, REGISTER_BYTE, REGISTER_RAW_SIZE,
3967 MAX_REGISTER_RAW_SIZE, REGISTER_CONVERTIBLE,
3968 REGISTER_CONVERT_TO_VIRTUAL, REGISTER_CONVERT_TO_RAW): Float regs
3969 are now 10 byte extendeds, not 8 byte doubles.
3970 (FRAME_CHAIN_VALID): Make this config-dependent, since it differs
3971 for nindy versus vxworks targets. FIXME, this should possibly go
3972 in the target vector.
3973 (EXTRA_FRAME_INFO, INIT_EXTRA_FRAME_INFO): Cache both
3974 frame_saved_regs and arg pointer with each frame.
3975 (FRAMELESS_FUNCTION_INVOCATION): New leafproc support.
3976 (FRAME_ARGS_ADDRESS): Use cached result.
3977 (FRAME_ARGS_ADDRESS_CORRECT): New, avoids g14 guessing.
3978 (FRAME_FIND_SAVED_REGS): Change arg to subsidiary fn.
3979 (PRINT_RAMDON_SIGNAL): Call print_fault.
3980 (POP_FRAME): Now works.
3982 * tm-nindy960.h: Break this off tm-i960.h. NINDY-specific
3983 option parsing and startup; STACK_END_ADDR, FRAME_CHAIN_VALID,
3984 BREAKPOINT, and DECR_PC_AFTER_BREAK are here.
3985 (ADDITIONAL_OPTION_HANDLER): use target_load, not
3988 * tm-vxworks960.h: Break this off tm-i960.h. VxGDB specific
3989 startup; DECR_PC_AFTER_BREAK, and FRAME_CHAIN_VALID are here.
3991 * valarith.c (value_subscripted_rvalue): Avoid handling
3992 floats and doubles specially; it gave alignment errors. Lint.
3994 * valops.c (value_of_variable, value_of_this): Error if unknown
3997 * valprint.c (print_floating): Bcopy rather than pointer-deref,
3998 to avoid alignment problems.
3999 (value_print): Handle unknown value address.
4000 (cplus_val_print): Two args are ignored; remove them. Change caller.
4001 (val_print): Use unpack_long rather than pointer-deref.
4004 (unpack_long, unpack_double): Use bcopy rather than pointer-deref
4005 to avoid alignment problems.
4006 (value_being_returned): Error if return value unknown.
4007 (set_return_value): Add bogosity warning, FIXME. *
4009 * TODO: A woman's work is never done.
4011 * Makefile.dist: Distribute REMOTE_OBS into tconfig files.
4012 Separate INCLUDE_CFLAGS for use with lint. Add LINTFILES.
4013 Add ieee-float.o to OBS.
4014 * tconfig/{nindy960,vxworks68,vxworks960}: Include the desired
4015 REMOTE_OBS remote-interface files in the TDEPFILES and TM_FILE.
4016 * tconfig/i960: FIXME. Half-merge, produce warning if config'd.
4018 Changes to generalize the VxWorks RPC protocol slightly, to handle
4019 i960 as well as 68000.
4021 * vx-share/dbgRpcLib.h (VX_SOURCE_STEP): Add.
4022 * vx-share/reg.h: Produce i960 regs #ifdef I80960
4023 * vx-share/xdr_ptrace.c: Skip FPA registers if 960.
4024 * vx-share/xdr_rdb.h: Add SOURCE_STEP struct and xdr decl.
4025 * vx-share/xdr_rdb.c: Add xdr_SOURCE_STEP routine.
4026 * vx-share/xdr_regs.c: Add xdr_regs, xdr_fp_status, xdr_ext_fp
4027 for i960. Change xdr_vectors to xdr_opaques for 68k registers,
4028 so they will move in target byte order rather than network
4029 byte order (happens to be the same).
4031 Mon Feb 25 03:41:44 1991 John Gilmore (gnu at cygint.cygnus.com)
4033 * tm-convex.h (END_OF_TEXT_DEFAULT): Remove #if 0'd block.
4035 Sun Feb 24 00:55:53 1991 John Gilmore (gnu at cygint.cygnus.com)
4038 Add contribution lines to various files, showing where they
4041 * breakpoint.c (break_insn, check_break_insn_size,
4042 read_memory_nobpt): Remove to mem-break.c.
4044 * xm-*.h, param-no-tm.h, tm-29k.h, valprint.c: Change BYTE_ORDER to
4047 * tm-29k.h (STAB_REG_TO_REGNUM): Warn user if symbol table
4048 entry has bad register number. This change is not
4049 tested in this release, FIXME.
4051 * frame.h: Eliminate Frame_unknown in favor of a simple zero.
4054 * value.h: Force value's contents field to be aligned to hold
4055 at least a double or a long long (if supported). This avoids
4056 doing bcopy's in and out of the contents field.
4058 (step_1): Avoid coredump under obscure circumstances when we
4061 * symtab.h (misc_info): Add field to misc function vector for
4062 any kind of cached information the target code desires. AMD
4063 29000 uses this to avoid repeating examine_function_prologue's.
4065 * coffread.c: Lint. Remove static symfile, read_section_header.
4066 core.c (have_core_file_p): Lint: remove.
4067 expprint.c (print_subexp): Lint.
4068 infptrace.c, valops.c, valprint.c: lint.
4070 Roll in changes from vxgdb-5.0.1:
4072 * symtab.h: Comment byte order of each address class. Add
4073 LOC_LOCAL_ARG for frame-relative args (960).
4074 expread.y: Use LOC_LOCAL_ARG where LOC_ARG is used.
4075 symtab.c, symmisc.c: ditto.
4077 * infrun.c (init_wait_for_inferior): Clear stop_signal.
4079 * remote.c (remote_resume): Error if resume with a signal.
4081 * symfile.c (prim_record_misc_function): Clear misc_info.
4082 (fill_in_vptr_fieldno): Check stub type of arg.
4084 * valops.c (value_cast): Avoid looking up names of types whose
4085 name we don't know, to prevent coredump. Sun CC produces typedef
4086 rtx and the name of *rtx is zero...
4088 Mon Feb 18 21:16:25 1991 John Gilmore (gnu at cygint.cygnus.com)
4090 Roll in changes from final AMD 29000 port (Tiemann).
4092 tconfig/am29k: Add COFF_ENCAPSULATE and TARGET=TARGET_AM29K
4093 for ../include/a.out.encap.h. This might not work now that BFD
4094 is separately compiled. Instead, BFD support for encap will have
4095 to translate machine type 29k into the right COFF_MAGIC.
4097 * infcmd.c: Remove references to inferior_pid that aren't used
4098 in actual ptrace calls; use target_has_execution, etc.
4099 (have_inferior_p): Remove function.
4100 (program_info): Print target info rather than "process number";
4101 avoid gratuitous messages unless from_tty.
4102 (run_stack_dummy, finish_command): Set proceed_to_finish.
4103 infrun.c: Remove inferior_pid refs. Decl & init proceed_to_finish.
4104 main.c: Lint. Lose have_inferior_p().
4105 inferior.h (have_inferior_p): Remove, lint.
4106 (proceed_to_finish): Add flag to ask that all regs be saved
4107 by normal_stop, for the few commands that need it, speeding up
4108 serial I/O. Add comments to stop_registers.
4110 * remote-eb.c: Remove newline from breakpoint message we grep
4111 for. Never time out when running the user program.
4115 Wed Feb 13 15:34:40 1991 John Gilmore (gnu at cygint.cygnus.com)
4117 Roll in changes from vxgdb-5.0.1:
4119 * dbxread.c (read_dbx_symtab): If we encounter a "FORTRAN COMMON"
4120 symbol in its raw form, we are processing an unlinked ".o" file.
4121 See if the target environment has assigned it an address, using
4122 target_lookup_symbol (VxWorks does), and enter it into the symtab
4125 * tm-vxworks.h (FRAME_CHAIN, FRAME_CHAIN_VALID): Override usual
4126 68k versions for a simpler version that assumes zero FP at bottom.
4127 Fixes bug of truncated stack reports.
4129 * target.h (target_lookup_symbol): Define this routine's args
4130 and result, finally.
4132 * target.c (nosymbol): Default routine for target_lookup_symbol.
4133 (target_default): Default lookup_symbol and call_function too.
4134 (files_info): Only print has_all_memory warning if a non-dummy
4137 * remote-vx.c (vx_read_register, vx_convert_to_virtual,
4138 vx_convert_from_virtual): If target does not have floating point,
4139 zero register "values", and avoid doing cross-net conversions.
4140 (vx_lookup_symbol): Rename net_lookup_symbol, add to vectors.
4141 (vx_open): Rearrange code that attaches to target and reads
4142 symbols for all loaded modules, to work if some of the modules
4143 are not accessible. Add symbol_stub() and add_symbol_stub()
4144 as callbacks from catch_errors(). Allow connect attempt to be
4145 interrupted painlessly with ^C (FIXME, there are still some bugs
4146 if the interrupt happens during symbol reading.). Print
4147 final message with puts_filtered, since symbol messages are
4152 * main.c (catch_errors): Only print errstring if non-null.
4153 (command_loop): Avoid an ioctl per command to test ISATTY.
4155 * remote-vx.c (net_load): make static; avoid sophomoric msg.
4156 (vx_xfer_memory): Return correct result!
4157 (vx_files_info): Indicate whether target has float or not.
4158 (vx_lookup_symbol): Complain, not error, if target gone.
4159 (vx_open): Print "Connected" msg before disabling immediate-quit.
4160 [FIXME: lookup_symbol and vx_open changes need testing.]
4162 target.c, remote-eb.c, inftarg.c, am29k-opcode.h, target.h,
4163 tm-29k.h, tmm-vxworks68.h, symfile.c, gdb-int.texinfo: Add
4164 contributor lines and update copyrights to 1991.
4166 Changes from an attempted H-PUX host port:
4168 * infptrace.c (PT_ATTACH, PT_DETACH): Handle HP/UX, which
4169 defines PT_ATTACH and PT_DETACH but not PT_KILL.
4170 * remote-eb.c (eb_open): Misplaced endif kills sysv H/PUX.
4171 * remote-vx.c: include <sys/time.h> for HPUX.
4172 * hp300hpux-xdep.c (fetch_core_registers): Rewrite old
4173 "core_file_command" routine to BFD regime. May not work yet.
4175 Attempted port of "gdb-3.4 Van Jacobson xgdb" to modern gdb.
4177 * xgdb.c: Replace X10 version with some VJ version.
4178 (FIXME: Its copyright assignment is not on record.)
4179 * xgdb.c: Update include files to X11R4 (Xaw crud).
4180 (xgdb_display_source, create_text_widget): fix call to
4181 get_filename_and_charpos. Rewack source window stuff for X11R4
4182 (gleaned from include files, and "nm's" of binary libraries, since
4183 I had no doc available).
4184 (append_selection, append_selection_word): Disable with FIXME
4185 since R4 changed interface here.
4186 (create_buttons): Add back the old set of buttons.
4187 (xgdb_create_window): Fix call to XtInitialize (&argc not argc).
4189 * Makefile.dist (xgdb, xgdb-init.c): Update for X11R4 on Suns.
4190 Roll VERSION to 3.94 (not yet final though).
4192 Sat Feb 9 09:46:25 1991 John Gilmore (gnu at cygint.cygnus.com)
4194 * obstack.h (obstack_ptr_grow, obstack_ptr_grow_fast,
4195 obstack_int_grow, obstack_int_grow_fast): Eliminate
4196 cast on left of assignment, which gives MIPS cc fits and is
4199 * sparc-pinsn.c (print_insn): Eliminate 'set' test, subsumed by
4200 F_ALIAS. Use printf, not fprintf, when not passing a file
4202 (compare_opcodes): Check that identical instructions have
4203 identical opcodes, complain otherwise.
4205 * sparc-opcode.h (st %fsr): Fix opcode "lose" mask. This
4206 was reported by Roland McGrath.
4207 (unimp): Only match if exactly zero instruction. (Roland)
4208 (branches and traps): Generate all variations of these
4209 instructions with macros, based on a single call that defines
4210 each condition name and its binary representation.
4211 (set): Turn on alias bit, to avoid test in sparc-pinsn.c.
4213 * valprint.c (val_print_fields): Take, and use, format parameter.
4214 This means that "p/x struct" again prints the elements in the
4215 desired format. Changed callers.
4217 * stack.c (frame_info): Use filtered output, and indicate wrap
4218 points. Remove kludgy formatting designed to avoid line wrap.
4220 * utils.c (wrap_here): If the line is already full (because
4221 we had printed a long indent or long wrapped string), do an
4222 immediate newline-and-indent.
4224 * m68k-pinsn.c (print_insn_arg): Bugfix from
4225 ntmtv!thompson@ames.arc.nasa.gov (Mike Thompson): 'bkpt #0'
4226 instruction is incorrectly disassembled as bkpt #8.
4228 * dbxread.c (end_psymtab): Bugfix from Peter Schauer
4229 <pesrem@regent.e-technik.tu-muenchen.de>: If you want to set a
4230 breakpoint in a *.y file gdb will say Reading in symbols for *.y...
4231 and then will dump core (sometimes). I traced it back to an
4232 uninitialized symfile_name in psymtab_to_symtab.
4233 (const_vol_complaint): Add quotes to message.
4234 (define_symbol): Only believe line number if gcc_compiled.
4235 Avoid allocating symbol if we will not return it.
4237 Add target strata support so that newly established targets go
4238 into their right place in the target stack (e.g. a new exec file
4239 doesn't wipe out the ability to access the running process).
4241 * target.h, core.c, exec.c, inftarg.c, remote-eb.c,
4242 remote-nindy.c, remote-vx.c, remote.c, target.c: Add to_stratum
4243 and initialize it properly in all the targets.
4245 * target.h: Document strata. Change return type of push_target.
4247 * target.c (nomemory): new function for dummy memory access.
4248 (tcomplain): Rename complain, now also used in symfile.c.
4249 (push_target): Push targets within strata. New return value shows
4250 whether new target is on top of stack or not. Always keep dummy
4252 (target_files_info): Ignore dummy target.
4254 * core.c (core_open): Warn user, and skip accessing file, if the
4255 core target is not the topmost target in the stack.
4256 * remote-nindy.c (nindy_create_inferior): Avoid unpush_target, now
4259 * remote-vx.c: Remove vx_prepare_to_store from vxworks memory
4260 target_ops, it doesn't belong there since we have no regs there.
4261 Change name of target from machine => memory to clarify.
4263 Thu Feb 7 16:32:09 1991 John Gilmore (gnu at spiff.cygnus.com)
4265 * Freeze version 3.93 for release.
4267 * Makefile.dist: Handle vx-share and nindy-share subdirs
4268 properly when building gdb.tar.Z.
4270 * symtab.c: lint; add no_symtab_msg to consolidate the messages
4271 printed in various places, so I could change just one copy.
4273 * dbxread.c, coffread.c: Change references to bfd->iostream
4274 to cast to FILE *, now that BFD avoids needing types defined
4275 in other header files.
4277 Tue Feb 5 21:39:35 1991 John Gilmore (gnu at cygint.cygnus.com)
4279 * command.c, dbxread.c, expprint.c, infcmd.c, infptrace.c,
4280 infrun.c, printcmd.c, remote-nindy.c, source.c, sparc-tdep.c,
4281 sparc-xdep.c, symfile.h, symmisc.c, utils.c, valprint.c: Lint
4282 (actually gcc -Wall).
4284 * dbxread.c: Remove first_global_sym, last_global_sym, since
4285 they are never referenced.
4287 * defs.h (baud_rate): Declare.
4288 main.c: Define it, and add the -b option to set it.
4290 * gdb-int.texinfo: Add text on how to define a new host or target
4291 architecture, prompted by Per Bothner's questions about MIPS
4294 * gdb.texinfo: Document "complaints". Change doc of -q since
4295 gdb no longer prints the copyright and blurb if you specify a file
4296 name to be debugged (just like Emacs). Add doc for Nindy-specific
4297 command line flags for specifying target serial port and such.
4298 Update copyright to 1991.
4300 * gdbcore.h: Remove a large mass of now-useless crud, since BFD
4301 has taken over for us the job of ripping up executable files. The
4302 crud caused Per Bothner's port to not compile.
4304 * infrun.c (normal_stop): Avoid printing "Program exited
4305 normally" if we are in batch mode. This allows a GDB which
4306 executes a program on a target system, to behave like a Unix
4307 command (input from stdin, output to stdout, no extraneous
4310 * main.c (main): Allow additional machine-dependent command line
4311 options to be specified with the ADDITIONAL_OPTIONS,
4312 ADDITIONAL_OPTION_CASES, ADDITIONAL_OPTION_HELP, and
4313 ADDITIONAL_OPTION_HANDLER macros. Also allow machine-dependent
4314 processing to occur just before the main loop with
4315 BEFORE_MAIN_LOOP_HOOK.
4316 (main): If a "core file" argument is specified, and it is not a
4317 core file, try it as a process ID to attach.
4318 (symbol_completion_function): Attempt to cope with
4319 "show screen-" TAB, not very successfully. This needs more work,
4321 (batch_file): New function, returns whether we are reading
4322 commands from an interactive tty on stdin, or from somewhere else.
4323 Called by normal_stop since it doesn't get from_tty passed down
4324 to it like many commands do.
4326 * remote-nindy.c: Handle command line options for nindy
4328 (nindy_before_main_loop): Prompt user for tty name if they
4329 don't specify it before getting to the interactive command loop.
4331 * tm-i960.c: Add ADDITIONAL_OPTIONS, etc, to handle -O, -brk,
4332 and -r command line options. Also add hook before main loop
4333 to make it easy to specify a tty.
4335 * TODO: More things to do, one done.
4337 Mon Feb 4 23:57:39 1991 John Gilmore and Mike Tiemann (at cygint.cygnus.com)
4339 * dbxread.c: Make complaint() calls pass pointer, not struct.
4340 Add complaints about badly formatted C++ type information
4341 (const/volatile indicator, and parse errors resulting in
4342 error_type). Fix C++ virtual member fn comment.
4343 (read_struct_type): Avoid bumping pointer if we got a parse
4344 error; this prevents our walking beyond the end of a string.
4345 Terminate loop on null char as well as semicolon.
4346 (process_one_symbol): Fix the LBRAC fix so that it uses the
4347 last previous SLINE, FUN, or SO record's PC address. C++ debug
4348 symbols did not have SLINE records in a useful order compared
4349 to the LBRAC records.
4350 (define_symbol): Handle "catch" records.
4352 * symtab.c (check_stub_type): Added new complain
4353 `stub_noname_complain' and added a consistency check to
4354 keep the debugger from crashing when finishing from an
4355 exception frame. A real fix will be needed later.
4357 Sat Feb 2 10:43:05 1991 John Gilmore (gnu at cygint.cygnus.com)
4359 * infcmd.c (attach_command): Make global.
4361 * Makefile.dist (REMOTE_OBS): Make these compile by default,
4362 but make them easy to comment out. Perhaps later they should
4363 be enabled by what CPU you configure for? FIXME.
4364 (VERSION): Roll to 3.93.
4365 (pinsn.o): Remove rule for obsolete file.
4366 (dbxread.o,coffread.o,mipsread.o): Use ${srcdir} explicitly.
4368 Run down a problem that manifested by printing the wrong function
4369 name in stack traces of read_ofile_symtab. Turned out that the
4370 problem was the SunOS 4.1.1 (and previous) C compiler outputs
4371 the LBRAC symbol with an address in the *data* segment, which
4372 blew our binary search through the blocks.
4374 * dbxread.c: Use the complain() facility consistently to bitch
4375 about problems in the symbol file we are reading.
4376 (finish_block): Add code to check the nesting of the blocks;
4377 complain and Procrust them to fit if wrong.
4378 (make_blockvector): Check the order of the blocks, complain
4379 [but don't cope] if wrong.
4380 (process_one_symbol): ifndef SUN_FIXED_LBRAC_BUG, check LBRAC
4381 symbols to be sure their PC value is greater than the last SLINE
4382 (line number) symbol we've seen, complaining and adopting the
4383 SLINE PC value if wrong.
4385 * symfile.h (struct complaint, complaint_root, complain,
4386 clear_complaints): Add.
4387 * symfile.c (complain, complaint_root, clear_complaints): Add
4388 facility to deal with non-fatal complaints and to regularize their
4390 (symbol_file_add): Clear complaint counters to allow new complaints.
4391 (initialize_symfile): Add 'set complaints' and 'show complaints'.
4393 * dbxread.c (dbx_symfile_read): Remember the address and size
4394 of the string table for the main symbol file, so we won't read it
4396 (dbx_psymtab_to_symtab): Fix the check for main symbol file,
4397 to avoid reading the string table yet again. Lint.
4398 (throughout): Improve filtered output, including word wrap.
4399 (read_range_type): Improve Bothner's fix to handle other types too.
4401 * utils.c: Improve line wrap implementation. Handle unlimited
4402 width by making chars_per_line unsigned.
4403 (puts_filtered): New, easy, function.
4405 * defs.h (puts_filtered): add.
4407 * mipsread.c (compare_symbols, sort_symtab): Remove these fns,
4408 call the identical sort_symtab_syms() in symfile.c instead.
4410 * expread.y: Suggest the `file' command rather than `symbol-file'.
4412 * command.h (enum var_types): Add zinteger for seroable
4414 * command.c (do_setshow_command): Handle var_zinteger. Restructure
4415 nested if's into a switch.
4417 * breakpoint.c (bpstat_print): If bpstat "print" flag is not set,
4418 we did not stop because of a breakpoint (it must have been for
4419 some other reason, like a "stepi"), so don't print anything.
4421 * symtab.c: Include <sys/types.h> all the time. Now that BFD
4422 doesn't include <sys/types.h>, old SunOS's require it for
4425 Sat Feb 2 10:39:15 1991 Per Bothner (bothner@cs.wisc.edu)
4427 A test port of gdb-3.92.6 to the Sony NEWS.
4430 Don't normally link in remote- or vx stuff.
4431 Some of it doesn't compile, and it wastes space for 99% of the users.
4432 Remove reference to no-longer-used HAVE_VPRINTF.
4433 Fixed BFD_DEP typo to BFD_DIR.
4435 Fix cast in arg to bfd_h_getlong.
4436 Make char *prefix be const.
4437 Fix how certain range types are mapped into builtin unsigned int types.
4439 Remove 2 #includes. They cause errors (on Sony, at least),
4440 and aren't needed (they wern't in earlier versions).
4442 print_address_symbolic should never demangle labels
4443 (since it prints *assembler-level* labels).
4445 [This was superseded by the change to printcmd below.]
4448 Add some "volatile" return types to avoid warnings.
4449 If MISSING_VPRINTF add vprintf function and not just macro
4450 (since vprintf is used in printcmd.c).
4452 Unless __GNUC__, use obstack_grow instead of obstack_ptr_grow.
4453 (The latter isn't grokked by some PCC-based compilers.)
4455 [This change is in abeyance, we prefer to fix obstack_ptr_grow.]
4457 Make chunk size of dont_print_obstack 32*4 instead of default 4096.
4458 * nindy-share/coffstrip.c
4459 Added some forward declarations (otherwise, gcc complains
4460 about implicit extern redefined as static).
4462 Sun Jan 20 02:38:19 1991 John Gilmore (gnu at cygint.cygnus.com)
4464 Changes inspired by Per Bothner:
4465 * printcmd.c (print_address_symbolic): Take additional parameter
4466 specifying whether to demangle.
4467 (print_address): Pass in asm_demangle to control demangling.
4468 (print_address_demangle): New fn, takes explicit arg to control
4470 * utils.c: Add new vars demangle and asm_demangle, and let them
4472 (fputs_demangled): If !demangle, just print the argument.
4473 (fprint_symbol): If !demangle, just print raw symbol.
4474 * valprint.c (val_print): Call print_address_demangle rather than
4475 print_address, to cause demangling to depend on the global
4476 rather than assembler-level demangling setting.
4477 * WHATS.NEW, gdb.texinfo: Document.
4479 * main.c (show_command): Show all settings if no arg.
4480 (initialize_main): Make "info set" the same as naked "show".
4481 * command.c (cmd_show_list): Handle prefix commands in the
4482 list, and print the name of the setting as well as its English
4483 description and value.
4485 Allow gdb functions to specify where a line should wrap if it
4486 exceeds the size of a terminal line. Use it to make the output
4488 * utils.c (set_screen_width_command): New fn, mallocs a buffer
4489 of the right size when screen width changes.
4490 (set_screensize_command, screensize_info): Remove #if 0'd fns.
4491 (wrap_here): New fn, indicates a point in the output where we
4492 should wrap the line rather than just letting it overflow at a
4494 (fputs_filtered): Implement wrapping.
4495 (n_spaces): New fn, returns a pointer to N spaces.
4496 (print_spaces_filtered): Use n_spaces.
4497 * defs.h (n_spaces): Declare.
4498 * stack.c (print_frame_info): Wrap with 4-space indent after
4499 fn name and before filename and line number.
4500 * printcmd.c (print_frame_args): Wrap with 4-space indent
4501 before each argument name is printed.
4502 * valprint.c (value_print): Wrap with no indentation before
4504 (val_print_fields): Wrap with indentation relative to nesting
4505 level before each field name.
4506 (val_print): Wrap with nesting indentation before array elements.
4507 * command.c (do_setshow_command): Avoid extra newlines,
4508 wrap with 4-space indent around values printed, end with period.
4509 * WHATS.NEW, gdb.texinfo, gdb-int.texinfo: Document.
4511 * breakpoint.c (breakpoint_1): Implement addressprint for
4512 "info breakpoints" display. Change file name and line number
4513 format to " at file:nnn" rather than " (file line nnn)".
4514 * gdb.texinfo: Document.
4517 Fri Jan 18 07:21:25 1991 John Gilmore (gnu at cygint.cygnus.com)
4519 Frozen for gdb-3.92.6 release.
4521 README, WHATS.NEW: Update for 3.92.6 release.
4523 tconfig/{altos, i386v, i386v32, m88k, umax}: Eliminate
4524 coffread.o from configs since it is now built by default.
4525 tconfig/{3b1, altosgas, arm, convex, hp300bsd, hp300hpux,
4526 i386v-g, i386v32-g, isi, merlin, news, news1000, np1, pn,
4527 pyramid, symmetry, vax, vxworks68}: Eliminate dbxread.o
4528 from configs since it is now built by default.
4530 Makefile.dist: Update for release 3.92.6. Handle files that
4531 have been moved to ../include, ../getopt, or ../bfd. Add
4532 saber.suppress and tests directory. Add config.status to
4533 the release (it will say "none").
4535 coredep.c: Minor formatting fixes.
4537 These changes were made in early December but only checked in now:
4538 * nindy-share/Onindy.c, nindy-share/coffstrip.c,
4539 nindy-share/nindy.c: lint
4540 * nindy-share/nindy.c (ninStopWhy): Don't byteswap the
4541 register values coming back from the target; we store values
4542 in target byte order everywhere.
4544 Wed Jan 16 19:01:37 1991 John Gilmore (gnu at cygint.cygnus.com)
4546 * am29k-opcode.h, am29k-pinsn.c: Add 29050 opcodes.
4548 * valprint.c (cplus_val_print, val_print_fields): New functions,
4549 which print C++ objects. They conspire to avoid printing a
4550 virtual base class more than once, following all the twists and
4551 turns of C++ virtual base rules.
4552 (val_print): Call the above rather than do it by hand.
4554 * symfile.c (symbol_file_add): Only reset symfile_mtime for main
4555 symbol file, not for added files like shared libs. This really
4556 needs to be generalized to a timestamp per file.
4558 * core.c (cleanup_core): Avoid coredump if no core file.
4560 * config.gdb: Accept -host or -target in place of +host or
4563 * coffread.c (find_linenos): Avoid desupported BFD interface
4564 to line numbers. We still read them manually rather than using
4565 BFD's "generic" features.
4567 * gdbrc.tex, threecol.tex: Add GDB reference card and its
4569 Makefile.dist: Add refcard to OTHERS list for creating tar files.
4571 * Makefile.dist: Eliminate use of $< in explicit targets.
4573 * readline/Makefile: Use $< rather than $*.c, which does not
4574 include the VPATH in GNU Make.
4576 * tconfig/i960-bout, tconfig/i960-coff: These are identical
4577 copies of tconfig/i960, added for global configuration
4578 compatability. All i960 versions can read both coff and b.out.
4580 * tm-88k.h: Fix multiline macro that lacked \'s. Remove
4581 COFF_FORMAT and COFF_CHECK_X_ZEROES since these are now handled
4584 * TODO: Think of more things to do.
4586 Wed Jan 2 19:09:29 1991 John Gilmore (gnu at spiff.cygnus.com)
4588 tconfig/{am29k,i960,sun2*,sun3*,sun4*}: Eliminate config
4589 of sdb versus dbx debug symbols. Add kludge for 68881 80-bit to
4590 64-bit float conversion.
4592 tconfig/sun4, tconfig/sun3, xconfig/sun4, xconfig/sun3: Make
4593 equivalent to sun?os4 so global config works.
4595 Wed Jan 2 18:20:51 1991 John Gilmore (gnu at spiff.cygnus.com)
4597 Fix from Eberhard Mattes <mattes@azu.informatik.uni-stuttgart.de>
4599 * main.c: Only declare linesize once; declare pagesize not at
4600 all, since it is never used.
4601 (main): Clear newly allocated line before it is used.
4603 Fri Dec 28 00:13:42 1990 John Gilmore (gnu at cygint)
4605 Further stabilization for the Intel 960.
4607 * Makefile.dist: Parameterize the location of the "include"
4608 and "bfd" directories, as well as "getopt". Add symfile.c.
4609 Link in both dbxread and coffread. Fix up "make depend" to
4610 rewack the locations of include, bfd, and getopt in its output.
4612 * README: Document moving include files, improve some of
4615 * coffread.c: Move common code out to symfile.c. Change
4616 symbol_file_command style interface to use new *_symfile_init
4617 and *_symfile_read interface under BFD. Use BFD internal
4618 info to locate line table, symbols, etc.
4620 * core.c (core_fetch_registers): Rename to get_core_registers
4621 to avoid confusion with fetch_core_registers.
4622 (register_addr): Move to coredep.c, which is already machine
4623 dependent. This leaves core.c pretty clean of dependencies.
4625 * coredep.c (register_addr): Accept this routine from core.c.
4627 * dbxread.c: Move common code (with coffread.c, etc) into new
4628 symfile.c. Each psymtab now contains a pointer to the
4629 format-dependent function that knows how to read it in. Make
4631 (dbx_psymtab_to_symtab): Renamed from psymtab_to_symtab_2.
4632 (process_one_symbol): Add code to complain about a "compiler bug
4633 we muzzle here", if we actually see it.
4635 * eval.c (evaluate_subexp): Insert missing "break" statements
4636 in code that determines whether a variable is an lvalue in
4637 memory, register, or whatever. I detected this via a compiler
4638 bug in which it *almost* mashed out the whole switch statement.
4640 * gdb-int.texinfo: Add minor sections on configuring gdb for
4641 release, and about the README file.
4643 * infcmd.c (registers_info): Fix formatting somewhat. Still
4644 not as pretty as before, but it handles byte swapping.
4646 * remote-nindy.c: If data cache routines are interrupted while
4647 waiting for the remote end, be sure that any uninitialized cache
4648 blocks are on the free list, not on the valid list!
4650 * symfile.h: Flesh out this header file with all the various
4651 routines and variables that have been merged in from dbxread.c
4652 coffread.c, and symtab.c to symfile.c.
4654 * symfile.c: New file, containing code common to dbxread.c,
4655 coffread.c, and some code from symtab.c. All generic code for
4656 reading symbol files should be in here now.
4657 (unrecord_misc_function): Remove unused function.
4659 * symtab.h: Remove file-reading things to symfile.h.
4661 * symtab.c: Remove file-reading things to symfile.c.
4663 * tm-i960.h: Fix FRAME_CHAIN types; define PRINT_RANDOM_SIGNAL
4664 to decode i960 fault types.
4666 * target.h, remote.c, remote-eb.c, remote-vx.c, remote-nindy.c,
4667 target.c: Change type of the "resume" function from int to void,
4668 since its result was never used.
4670 Sat Dec 22 02:51:40 1990 John Gilmore (gnu at cygint)
4672 * main.c: Replace "stupid" with "caution"; you now "set caution
4675 * printcmd.c (print_scalar_formatted): Fix typo in 'g' format
4677 * infcmd.c (do_registers_info): Call val_print to deal with the
4678 byte order of the registers being printed. FIXME, this makes
4679 the formatting of the output uglier.
4681 * infcmd.c (wait_for_inferior): If PRINT_RANDOM_SIGNAL is
4682 defined, call it for signals the debugger doesn't itself use.
4683 The i960 uses this for more detailed fault information.
4685 * remote.c (remote_open): If arg is null, print help rather than
4688 * sparc-xdep.c (register_valid): Avoid declaring size, since
4689 various modules will think of various sizes depending on the
4690 architecture of their tm-file. FIXME, we need protection against
4691 actually entering one of those modules, which would clobber
4692 storage if not for the target architecture compiled into gdb.
4694 * stack.c (up_command, down_command): Always print the frame
4696 (up_silently_command, down_silently_command): New commands
4699 * i960-pinsn.c (reg), i960-tdep.c: Lint.
4701 * i960-tdep.c (i960_frame_chain_valid): Lookup_symbol now takes
4702 more parameters than it used to.
4704 * findvar.c (registers): Increase slop to 256 bytes, which should
4705 protect us against even most RISC machines with large register
4707 (locate_var_value): Move declaration inside related ifdef.
4709 * remote-nindy.c (): Use TIOCSETN rather than TIOCSETP
4710 throughout, to avoid throwing away buffered input from the board.
4711 (nindy_wait): Supply_register takes addr_of_value, not value.
4712 (i960_print_fault): Renamed from i80960_fault.
4713 (nindy_fetch_registers): Avoid have_regs stuff, just get them.
4714 (nindy_store_registers): Avoid regs_changed stuff, just stuff
4716 (nindy_create_inferior): Don't bother to write PC_REGNUM since
4717 we can set the PC in the call to proceed(). Unpush nindy_ops
4718 before pushing it on top, to avoid message to user. Eliminate
4719 commentary from Unix machines that just misleads here.
4720 (reset_command): Fix error message to suggest target command.
4722 Wed Dec 19 11:03:56 1990 John Gilmore (gnu at cygint)
4724 Release 3.92.5 as frozen.
4726 Stabilize the merged release...with help from lint, Saber C,
4729 Everywhere: Add include files needed to declare return types
4730 of functions called.
4732 * gdb.texinfo: Roland Pesch is documenting gdb, glory be!
4734 * breakpoint.h: Add undeclared breakpoint functions, and some
4735 functions for display handling since I couldn't think of a better
4738 * breakpoint.c (insert_breakpoints): Make code for disabling
4739 shared library bkpts more likely to work. It's used when we
4740 rerun a program and stop before the shared library has been
4742 (breakpoint_cond_eval, bpstat_stop_status): Pass arg as int,
4743 cast from pointer, so it squeezes through catch_errors.
4744 (bpstat_stop_status): Fix logic broken some time ago. We now
4745 always create a bpstat if the stop address matches a breakpoint,
4746 even if we don't stop there -- just like the old code used to do
4747 before I got my fingers into it (sigh).
4748 (breakpoint_1): Print "ignore count" after "stop only if"
4749 condition, since that's how it actually works.
4750 (mention): Handle watchpoints as well as breakpoints.
4751 (watch_command): use set_raw_breakpoint and mention to do most
4752 of the work (and initialize all the fields!). Only pass one
4753 arg to parse_c_expression, since that's all it takes.
4755 * command.c (not_just_help_class_command): Rename arg to args
4756 since we ignore "unused argument" warnings on vars named "args".
4757 inflow.c (child_terminal_info): ditto.
4758 infptrace.c (kill_inferior): ditto
4759 main.c (catch_errors, version_info, quit_command, pwd_command,
4760 source_command, dump_me_command, editing_info,
4761 set_history_size_command, set_history, show_history,
4763 stack.c (locals_info): ditto
4764 target.c (target_files_info): ditto
4765 valprint.c (set_input_radix, set_output_radix): ditto
4767 * core.c: Remove old variables for handling core and exec file
4768 sections (data_start, data_end, stack_start, stack_end,
4769 reg_stack_start, reg_stack_end, reg_stack_offset, text_start,
4770 text_end, exec_data_start, exec_data_end, text_offset,
4771 exec_data_offset, data_offset, stack_offset). They're
4772 superseded the more general build_section_table and
4774 (get_exec_file): Mention the `file' command.
4775 (read_memory_check): Rename to memory_error, and only call it
4776 in the case of an actual error.
4777 (read_memory, write_memory): call memory_error.
4778 (core_fetch_registers): Register section name is ".reg".
4780 coredep.c: Remove a bunch of crud now that all this file does
4781 is pull the registers out of a core file.
4782 (fetch_core_registers): Rewrite to actually work, I hope.
4784 dbxread.c: Use a.out.gnu.h, not system a.out, now.
4785 Replace index() with strchr(). Remove all the pre-BFD macro
4786 definitions for accessing the symbol file.
4787 (struct dbx_symfile_info): Encapsulate the information that
4788 dbx_symfile_init needs to pass to dbx_symfile_read in this
4791 (dbx_new_init, dbx_symfile_init, dbx_symfile_read,
4792 dbx_symfile_discard): Rearrange symbol file reading to divide
4793 the format-specific part from the format-independent part,
4794 leaving the format-independent part such as file name expansion
4795 and opening in symtab.c. This replaces
4796 partial_symbol_file_open and partial_symbol_file_read.
4797 Symbol_file_read, add_file, add_file_target_command,
4798 add_file_addr_command move to symtab.c. Pass an explicit
4799 "mainline" flag for when reading the main symbol table, rather
4800 than relying on the offset address to be zero or nonzero.
4802 (dbx_symfile_read): Don't allow void *'s to be printed as
4804 (SWAP_SYMBOL): Use bfd routines to byte-swap the symbols.
4805 (ADD_PSYMBOL_TO_LIST): Make the "function call rather than
4806 macro" debug version really work.
4807 (read_dbx_symtab): Remove unref'd parameter inclink.
4808 Avoid swapping N_SLINE symbols, for speed.
4809 Merge N_TEXT!N_EXT case with the other external symbol
4810 definitions' case. Add comments.
4811 (start_psymtab): Allocate the symfile name in the psymtab on
4812 the psymbol_obstack, rather than using the caller's storage.
4813 (end_psymtab): Only allocate a dependencies list if there are
4815 (psymtab_to_symtab_2): Use BFD when reopening file to read
4816 its symbols for real.

4820 (read_range_type): Add FIXME about comparing a long to 1<<32.
4822 * coffread.c: Minor changes to move things closer to the new
4823 regime with symtab.c and dbxread.c Major work is still needed
4826 * exec.c (exec_file_command): Remove old variables (see core.c
4828 (xfer_memory): If memory transfer is right at the end of a
4829 section, don't lose.
4831 * findvar.c (get_saved_register): If value is in a real
4832 register, LVAL is lval_register, not lval_memory.
4834 frame.h: Declare print_sel_frame and record_selected_frame.
4836 gdb-int.texinfo: New file, for GDB internals documentation.
4837 Very simple, unformatted doc of cleanups is there for now.
4839 gdbcore.h: Remove obsolete variables that described a.out
4840 section addresses and offsets. (See core.c above.)
4841 Declare fetch_core_registers and registers_fetched.
4843 getopt.c: Declare char *alloca(); even on SPARC.
4845 infcmd.c (run_command): Call target_kill rather than
4847 (step_command, next_command, stepi_command, nexti_command):
4848 Declare from_tty parameter even though we don't use it.
4849 (run_stack_dummy): argument BUFFER is a char array, not
4850 a pointer to REGISTER_TYPE.
4851 (finish_command): using_struct_return needed a value *,
4852 not a struct symbol *.
4854 * infptrace.c (child_xfer_memory): To avoid dependency on
4855 where sections are in memory, try PT_WRITE_D and if that fails,
4856 try PT_WRITE_I. Most Unixes don't care which you use.
4858 * infrun.c (step_resume_break_shadow): Change to array to
4859 match other breakpoint shadow storage.
4860 (clear_proceed_status): Pass address of bpstat to
4861 bpstat_clear, not the bpstat itself.
4862 (child_create_inferior): FIXME comment about if the child
4864 (start_inferior): Remove old function.
4865 (child_open): Use target_kill rather than kill_inferior.
4866 (wait_for_inferior): Ditto.
4867 (insert_step_breakpoint, remote_step_breakpoint): Use
4868 new step_resume_break_shadow.
4870 * inftarg.c (child_wait): If all child processes die,
4871 pretend that the one being waited for exited with signal 42.
4873 * main.c (command_line_input): When scanning for comments,
4874 don't coredump on unclosed quotes.
4875 (quit_command): Use target_kill rther than kill_inferior.
4876 (_initialize_main): Rename class_user from "user" to
4879 * printcmd.c (print_command_1): Initialize "fmt" if no format
4880 is specified by the user.
4881 (print_frame_args): Only add to args_printed if we are
4882 actually fetching args from the stack (avoiding undefined
4884 (_initialize_printcmd): Remove bogus \{ from string.
4886 * remote-eb.c (eb_open): Avoid coredump on no argument.
4888 * remote-nindy.c: Bring out of Intel environment into new
4889 target environment. Remove all conditional compilation on
4890 I80960. Massive hacking throughout.
4891 (nindy_xfer_inferior_memory): New routine stolen from
4893 (nindy_create_inferior): New routine pieced together, probably
4894 not quite working yet.
4895 (nindy_ops): New target_ops struct for nindy.
4897 * remote-vx.c: Use write_memory rather than target_write_memory
4898 to get error checking.
4899 (vx_add_file_command, vx_open): Use symbol_file_add rather than
4901 (vx_create_inferior): Use target_terminal_ours...
4903 * signame.c (_initialize_signame): Always initialize, since
4904 we need the table for things other than psignal.
4906 * solib.c (solib_add): Use symbol_file_add, not add_file.
4907 (solib_address): Return boolean result rather than struct
4908 pointer which nobody else knows the type of.
4910 * sparc-tdep.c, valops.c: Use write_memory rather than
4911 target_write_memory, to get error checking.
4913 * stack.c (locals_info, catch_info, args_info,
4914 get_selected_block, frame_command, up_command): Use
4915 target_has_stack, rather than have_inferior_p or
4918 * sun3-xdep.c (fetch_core_registers): Rewrite for new BFD regime.
4920 * symfile.h: New file, defining the interface between the
4921 generic and object-file-specific symbol reading code.
4923 * symtab.c: Move generic symbol-reading interface to symtab.c,
4924 from dbxread.c, coffread.c, mipsread.c, etc. Add symtab_fns
4925 table to map BFD targets to symbol-reading modules in GDB.
4926 Change index to strchr.
4927 (lookup_struct_elt_type): Use error() rather than hand-made
4928 simulations thereof.
4929 (lookup_partial_symbol): Speedup slightly when length == 0.
4930 (symbol_file_add): New function.
4931 (symbol_file_command): Call it.
4932 (symfile_open, symfile_init): New function.
4933 (add_file_target_command, add_file_addr_command): moved from
4936 * target.c (target_command): use target_kill.
4938 * target.h (target_files_info): Don't declare, never called
4941 * tm-sun2.h, tm-sun3.h (STACK_END_ADDR): Use system include
4942 files to determine stack end address.
4944 * valarith.c (value_x_binop, value_x_unop): Change error message
4945 to be more useful. Pass proper argument to value_struct_elt.
4947 * valops.c (value_assign): FIXME comment that long long
4948 bitfields will break here.
4950 * Makefile.dist: Add symfile.h, remote-nindy.c, remote-eb.c.
4951 Update `make saber_gdb' to work better.
4953 * TODO: A woman's work is never done.
4955 * cplus-dem.c, environ.c, inferior.h, infrun.c, inftarg.c,
4956 main.c, obstack.c, printcmd.c, remote-eb.c, remote-nindy.c,
4957 remote-vx.c, remote.c, solib.c, source.c, sparc-pinsn.c,
4958 sparc-tdep.c, sparc-xdep.c, symmisc.c, symtab.c, symtab.h
4959 target.c, terminal.h, tm-sparc.h, tm-sunos.h, utils.c,
4960 valops.c, valprint.c, exec.c: Lint.
4963 Wed Dec 12 23:44:15 1990 John Gilmore (gnu at cygnus.com)
4965 Continuing Intel 960 port merge of GDB.
4967 * Makefile.dist: Merge i960 "nindy-share" files. Rename
4968 malloc.h to gmalloc.h to avoid name conflicts in /usr/include.
4969 Don't ship gdb.dvi in tar file. Link gdb with init.o, not init.c.
4970 Wack over "make depend" so it handles files in subdirectories
4971 vx-share, nindy-share, bfd, and in the current directory.
4973 * blockframe.c (get_prev_frame_info): Remove fatal error
4974 if stack not defined.
4976 * core.c (core_open, core_detach): New functions that handle
4977 the old "core-file" command as "target core" and "detach" instead.
4978 (core_file_command): Call them.
4979 (core_xfer_memory): Use common routine xfer_memory.
4981 * dbxread.c: Include a.out.gnu.h, not system a.out.h.
4982 dbxread now uses bfd for everything but symbol reading itself.
4983 BFD internals are used to drag out the relevant file offsets.
4984 (partial_symbol_file_open): Change args all around for BFD.
4986 * symtab.c: Rename "value" to "val" everywhere, so we can
4988 (symbol_file_command): New command, moved from dbxread.c
4989 and coffread.c. It uses BFD to read the file, then vectors
4990 based on its type, to dbx or coff symbol readers.
4991 * symtab.h: Extern a few vars for symbol_file_command.
4993 * target.h: Breakpoint takes a char * save area, not a char **.
4995 * valprint.c (val_print): When unpacking bitfields, offset
4996 the address in gdb of the value, if it is declared with a shorter
4997 type. Remove the last "runtime kludge test" of host byte order.
4999 * utils.c: Remove old my_bfd_read routine.
5001 * stack.c (frame_info): Use target_has_stack. Print program counter
5002 register's actual name rather than "pc", since it's called the
5003 "ip" (instruction pointer) on the i960 (sigh).
5005 * target.c (target_command): Add command for selecting a target
5006 type and calling its open routine. This is used for initiating
5007 communication with a particular target, in a generic way.
5009 * tm-i960.h: Update for modern gdb. Remove semicolons from
5010 various macros. Handle reading struct return convention, and
5011 error-out attempts to return structs with the "return" command.
5012 Be sure gdb doesn't think we know how to call functions in the
5015 * i960-tdep.c: Rename FRAME_CHAIN_VALID and FRAME_FIND_SAVED_REGS
5016 to i960_xxx in lower case.
5017 (arg_address): Circumvent errors due to LOC_ARG_BLOCK
5018 not being defined yet.
5020 * remote.c (remote_open): Call start_remote to initialize
5021 wait_for_inferior during open.
5022 (remote_xfer_inferior_memory): Return length written rather
5025 * remote-vx.c (target_command -> vx_open): Use new generic
5027 * remote-eb.c, inftarg.c, exec.c: ditto.
5029 * infrun.c: Fix comments.
5030 (attach_program -> child_open): Use new generic target command.
5031 (wait_for_inferior): Clear saved register values before target_wait,
5032 so target_wait can set some of them if convenient.
5034 * infptrace.c (fetch_inferior_registers, store_inferior_registers):
5035 Return success indicator, not void.
5036 (child_xfer_memory): Avoid fetching initial word if we'll
5037 overwrite it anyway.
5039 * infcmd.c (attach_command): Use new generic target open routine.
5040 (_initialize_infcmd): Update doc on attach and detach commands.
5041 (do_registers_info): Merge in a byte-order problem as a FIXME
5044 * findvar.c (find_saved_register): Avoid problem in current frame.
5045 (read_relative_register): Ditto.
5046 (write_register): Convert byte order on the way out.
5048 * exec.c (file_command): Add.
5049 (add_to_section_table, exec_command): Use new bfd_map_over_sections.
5050 (xfer_memory): Common function between core_xfer_memory and
5052 (exec_xfer_memory): Use it.
5054 * pn-opcode.h: Document that a "PN" is a Gould PowerNode.
5056 * breakpoint.c, breakpoint.h, symtab.h, value.h, frame.h, utils.c,
5057 valops.c, stack.c, target.c, sparc-xdep.c, source.c, printcmd.c,
5058 infcmd.c, i960-pinsn.c, eval.c, defs.h: lint and gcc -Wall.
5060 Sun Dec 2 16:45:06 1990 John Gilmore (gnu at cygnus.com)
5062 Merge Intel 960 port of gdb, continuing...
5064 * dbxread.c (partial_symbol_file_open, partial_symbol_file_read,
5065 symbol_file_command): Pass from_tty arg to hush 'em up.
5067 * coffread.c (symbol_file_command): Avoid output if from_tty != 1.
5068 Add magic numbers for 960 COFF format.
5070 Fri Nov 30 09:18:20 1990 John Gilmore (gnu at cygnus.com)
5072 Merge Intel 960 port of gdb, from Intel "1.2" release.
5074 CHANGE_LOG entries from their port, which was based on
5077 Thu Sep 6 11:02:22 PDT 1990
5078 Remove temp file if download is interrupted.
5080 Wed Aug 1 09:08:33 PDT 1990
5081 Now uses binary protocol to talk to NINDY.
5082 Old hex protocol (NINDY 2.13 and older) supported with -O switch.
5083 Times out after 5 seconds when trying to talk to NINDY.
5085 Tue May 29 12:54:49 PDT 1990
5086 Added variable baud rate (-b switch).
5087 Source code reorganization.
5089 Thu Apr 26 11:09:55 PDT 1990
5090 More cleanup of batch mode; specifically, execute "-s", "-e", and
5091 "-se" switches as soon as they are encountered on the invocation line.
5093 Fri Apr 20 13:47:15 PDT 1990
5096 Thu Apr 19 09:54:28 PDT 1990
5097 Add 'reset' command.
5099 Wed Apr 18 09:48:07 PDT 1990
5100 After opening remote tty, wait for 1 second to go by without input
5101 from it before trying to talk to NINDY (fixes problems with the
5102 Heurikon HK80/V960E).
5104 Mon Apr 4 16:33:05 PDT 1990
5105 Some output was not being suppressed in 'batch' mode.
5107 Thu Mar 22 15:31:11 PST 1990
5108 Ask user if old symbol table should be deleted when new file is
5111 Allow user to run a program downloaded before gdb960 was brought up.
5113 Correct "exec-file" help message for i80960 context.
5115 Correct bug in calculating user space address: could occasionally
5116 corrupt user program.
5118 Make sure to zero low-order bits in rip's because of bug in 960CA
5119 A-step part: could cause operation faults when "next"ing across
5122 Correct bug that made it impossible to get source line numbers for
5123 code loaded at addresses higher than 0x7fffffff.
5125 Wed Jan 10 12:43:22 PST 1990
5126 Open remote tty for exclusive use.
5128 Fri Jan 5 12:14:42 PST 1990
5129 Correct disassembly (CA manual was right after all):
5130 opcode for sysctl is 0x659
5132 Mon Oct 23 12:03:04 PDT 1989
5133 Use G960BASE and G960BIN environment variables to find 'sx' utility.
5135 Mon Oct 16 14:15:09 PDT 1989
5136 "sfr0"-"sfr31" should have been named "sf0"-"sf31"
5138 Mon Oct 2 15:56:31 PDT 1989
5140 Added 960CA disassembly support.
5142 To simplify maintenance:
5143 - eliminated use of symblic links on pinsn.c: use i960-pinsn.c
5145 - eliminated opcode.h: incorporates tables into i960-pinsn.c
5146 - moved 960-specific routines from i960-pinsn.c to i960-md.c
5147 - made disassembly interface identical to that in gdmp960.
5151 Wed Nov 28 21:32:48 1990 John Gilmore (gnu at cygint)
5153 * target.h: Allow targets to stack. Add target_has_memory,
5154 _registers, etc. Restructure memory access and "info files"
5155 to walk the target stack.
5156 * exec.c, core.c, inftarg.c, remote.c, remote-vx.c, remote-eb.c,
5157 target.c: Change tables to match target.h.
5158 * inflow.c (child_mourn_inferior): pop child_ops.
5159 (generic_mourn_inferior): Use new has_stack flag.
5160 * infptrace.c (child_xfer_memory): New memory regime.
5161 * inftarg.c (child_files_info): New "info files" regime.
5162 * remote-eb.c: New memory regime, new info files.
5163 * remote-vx.c: New memory regime, new info files. Now use
5164 separate targets for VxWorks attachment to machine, and
5165 actually running a process under VxWorks, since one has
5166 stack & execution & regs and the other doesn't.
5167 * remote.c: New memory regime, new info files.
5168 * sparc-xdep.c (fetch_core-registers): New memory regime.
5169 * target.c: New routines and support for stacked targets,
5170 new memory regime, new info files regime.
5173 Generalize section handling for an arbitrary number of sections,
5174 including use of the new BFD (binary file) library.
5175 * gdbcore.h: Add struct section_table.
5176 * exec.c (build_section_table): Iterate all sections and
5177 record what gdb needs to know about them.
5178 (exec_command): Use it.
5179 (exec_xfer_memory): Use the table.
5180 (exec_files_info): Print the table.
5181 * core.c (core_file_command, core_xfer_memory, core_files_info):
5183 * source.c (find_source_lines): Use bfd_get_mtime.
5184 * dbxread.c: Quick changes to make it compile with new BFD.
5185 * utils.c (error): Avoid using bfd_error in generic routines.
5187 * core.c (core_fetch_registers): Get from the ".regs" section of
5189 * sparc-xdep.c (fetch_core_registers): Use the .regs info.
5191 * inferior.h (attach_flag): Export.
5192 * infcmd.c (run_command): use new target_create_inferior.
5193 * infrun.c (child_create_inferior): Don't return result.
5194 * Makefile.dist (VERSION): 3.91.4.
5196 Fri Nov 23 28:15:38 1990 John Gilmore (gnu at cygint)
5198 * breakpoint.c (bpstat_num): Handle breakpoints which have
5199 since been deleted, such as temporary breakpoints.
5200 infcmd.c (program_info): ditto.
5202 * core.c (core_file_command): Display the frame where the core
5207 * remote-vx.c (target_command): Merge in target command from
5208 targ-vx.c. A few other cleanups.
5210 * TODO, Projects: Lots more stuff to do...
5212 Fri Nov 23 18:15:38 1990 John Gilmore (gnu at cygint)
5214 Massive changes to wall off the remote-debugging interface
5215 behind a function vector. The port to handle VxWorks targets
5216 is also part of this.
5218 All files: Replace references to renamed functions,
5219 remove references to remote_debugging, remove references to
5220 have_include_file, have_core_file in favor of target_has_stack,
5221 target_has_memory, etc.
5223 * Modularize the breakpoint interface.
5224 breakpoint.h (BREAKPOINT_MAX): New define sets max length of
5225 a breakpoint instruction.
5226 breakpoint.c: struct breakpoint's shadow_contents now sized as
5228 (insert_breakpoints): Vector to target to install breakpoints.
5229 (remove_breakpoints): Vector to target here too.
5230 Remove REMOTE_SA_SPARC kludges and other remote_debugging.
5231 sparc-tdep.c (single_step): Use new breakpoint interface for
5232 the single-step breakpoints.
5233 mem-break.c (memory_insert_breakpoint, memory_remove_breakpoint):
5234 New file, contains routines to insert and remove breakpoints by
5235 reading out the old contents and later replacing them. This is
5236 how ptrace breakpoints work, and many remote systems as well.
5238 * tm-vxworks68.h: New config file, overrides a few things for
5239 Wind River's preferences.
5241 * target.h: New file, for transfer vector used to talk to the
5242 inferior (child, attached, core, exec, remote, etc). All accesses
5243 to the thing being debugged should come through these vectors.
5244 target.c: New file, routines to handle transfer vector.
5245 (various files): Add transfer vectors XXX_ops for the various
5246 targets and pseudo-targets (core files, etc) we support.
5248 * breakpoint.c (bpstat_stop_status): Further explorations of
5249 watchpoints and why things don't work all the time.
5250 (bpstat_alloc): New fn to allocate a bpstat and chain it.
5252 * config.gdb: Only add "source ${srcdir}/.gdbinit" to
5253 the local gdbinit if it doesn't already have it.
5255 * core.c (core_ops): add and install.
5256 Allow core debugging without exec file.
5258 * dbxread.c (free_and_init_header_files): Merge two fns.
5259 (end_symtab): Free named symbol table when a new version comes in.
5260 (read_dbx_symtab): Relocate all kinds of symbols with base
5261 address. First step toward handling different text, data, bss
5263 (add_file_addr_command): Renamed add_file_command.
5264 (add_file_command): Vector to remote handler.
5265 Add "load" as an alias for "add-file" command.
5267 * defs.h: Allow "volatile" to be used in non-ANSI; use it for
5268 non-returning functions.
5270 * exec.c: Add exec_ops, and push it as a target when an exec
5273 * infcmd.c (run_command): Pass executable file name and arg list
5274 separately when starting an inferior. Permit "run" when no exec
5275 file is specified, for VxWorks.
5276 (detach_command): Move to child_detach in inftarg.c.
5278 * inftarg.c: New file. Unix-child-specific routines, and the
5279 child_ops structure.
5281 * inferior.h (registers): Export "registers" as the way for
5282 target dependent register handlers to find gdb's local copy of
5283 the registers. Rename "stop_after_attach" to "stop_soon_quietly"
5284 since it is now used by places that want wait_for_inferior to
5285 handle the grunge but want to see every trap from the inferior.
5287 * inflow.c (create_inferior): Pull out, and merge into infrun.c.
5288 Eliminate remote_debugging hooks in terminal handling.
5290 * infrun.c: Replace start_inferior with child_create_inferior.
5291 Move all the hair of Unix shells and ptrace idiosyncracies into
5292 child_create_inferior, so remote handlers don't have to deal.
5293 Remove running_in_shell. Rename stop_after_attach to
5294 stop_soon_quietly, and use it in a few other places where we want
5295 to just call wait_for_inferior and get control back on the first
5296 trap. trap_expected now never takes a value > 1.
5297 (init_wait_for_inferior): Initialize static vars when a new
5300 main.c (gdbinit): Add new hook for .gdbinit file name, let
5301 it be overridden by config files as GDBINIT_FILENAME.
5302 (DEFAULT_PROMPT): Add new hook for overriding (gdb) prompt.
5303 Both of these are used for VxWorks gdb.
5305 mcheck.c: rename include file "gmalloc.c" to avoid problems
5306 with system include file "malloc.c".
5308 param-no-tm.h: New include file, same as param.h but does not
5309 include the default "tm.h" file. This is used in files where
5310 the target is known, e.g. remote-eb.c or sparc-xdep.c.
5312 param.h: Now just a shell that includes tm.h and param-no-tm.h.
5314 remote-vx.c: New file, VxWorks remote debugging support. Uses
5315 RPC routines that are shared with the target system, in directory
5318 remote.c: Vectorize remote interface.
5320 source.c: Globalize source_path, and make an alias "l" for "list"
5321 since we now have the "load" command.
5323 sparc-xdep.c: Use new param-no-tm.h.
5325 symmisc.c (free_named_symtab): Add new function from Wind River.
5326 However, ifdef it out for now while we think about what it should
5329 tm-sun3.h, xm-sparc.h, xm-sun3.h, xm-symmetry.h: Move
5331 the xm- file, and change its name to CHILD_PREPARE_TO_STORE, since
5332 non-Unix-children handle this with their own code in the target
5335 Makefile.dist: Roll version to 3.92.3. Add vx-share stuff to
5336 source and target lists. Add vx-share to default list of include
5337 directories. Add new files to src and target lists: mem-break,
5338 target, inftarg, remote-eb, remote-vx, targ-vx. Be sure the
5339 ${srcdir} versions of munch and createtags are used.
5341 * valops.c (find_function_addr): Split out of call_function.
5342 (call_function_by_hand): Rename call_function; this function
5343 calls functions in the target by laboriously patching the target
5344 word-by-word with the right stack, args, regs, etc.
5347 Mon Nov 5 17:29:10 1990 John Gilmore (gnu at cygint)
5349 Handle AMD 29000 a bit better.
5351 * remote-eb.c (readchar): Mask received char log to make it readable.
5352 (remote_start): Pass arguments down to executing program.
5353 Make startaddr unsigned.
5354 infrun.c (start_inferior): Accept args, pass them to
5356 infcmd.c (run_command): Pass args down to start_inferior.
5358 * tconfig/am29k-aout, tconfig/am29k-coff: New files specifying
5359 the target object file format.
5360 tm-29k.h: Pay heed to COFF_ENCAPSULATE.
5362 * am29k-pinsn.c (print_insn): Print 0x on hex numbers in disassembly.
5363 am29k-tdep.c (examine_prologue): Better checking of function prefixes.
5365 Sun Oct 7 18:20:45 1990 John Gilmore (gnu at cygint)
5367 * Makefile.dist (VERSION): Roll version to 3.91.9 and freeze.
5368 * TODO: We did a few things, we have more to do though.

5371 * inflow.c (inferior_died): Clear deferred stores.
5373 * Debug problems with dummy frames and calls to the inferior.

5375 * sparc-tdep.c (do_restore_insn): Simplify.
5376 (sparc_frame_find_saved_regs): Simplify and fix what we find.
5377 (sparc_push_dummy_frame): Simplify and fix what we push.
5378 (sparc_pop_frame): Slightly more hair here, deciding whether
5379 we are restoring a saved PC or returning to a return address in %i7.
5380 * sparc-xdep.c (read_inferior_registers): Debug if valid reg is read.
5382 * utils.c (xmalloc, xrealloc): Return type depends on __STDC__.
5383 * symtab.h (xmalloc): ditto, for obstack_chunk_alloc.
5384 * obstack.h (chunkfun): ditto.
5385 * defs.h (xmalloc, xrealloc): ditto
5387 * utils.c (quit): Grab the terminal from the child if necessary.
5389 * inflow.c (term_status_command): Rename to term_info, change
5392 * sparc-pinsn.c (print_insn): Disassembly prefers real instructions.
5393 (is_delayed_branch): Speed up.
5394 * sparc-opcode.h: Add ALIAS bit to aliases. Fix up opcode tables.
5395 Still missing some float ops, and needs testing.
5397 * Support for input and output radixes other than base 10
5398 * defs.h (input_radix, output_radix): Declare.
5399 * expread.y (yyparse, parse_number): Handle changes of input
5400 radix, and ambiguous names-or-numbers in radixes >10.
5401 * printcmd.c (print_scalar_formatted): Print formatted hex
5402 numbers in varying column widths.
5403 * valprint.c (val_print): Use output_format to print scalar ints.
5404 (set_input_radix, set_output_radix, set_radix): Create.
5405 (set_output_radix): Set output_format from output_radix.
5406 (_initialize_valprint): add `set radix' but leave the others off.
5408 * main.c (execute_command): Let stupid questions be turned off.
5409 (_initialize_main): Handle "set stupidity", etc.
5411 * main.c, inflow.c, inferior.h, frame.h, command.c, defs.h,
5412 sparc-pinsn.c, sparc-xdep.c, value.h, valops.c, values.c: Lint.
5414 Tue Oct 2 11:20:02 1990 John Gilmore (gnu at cygint)
5416 * TODO, Makefile.dist, ChangeLog: Freeze for 3.91.8 release.
5417 bfd stuff is still screwed up, but with some manual work, it
5420 * breakpoint.c (bpstat_do_actions): Start over if a command
5421 proceeds the inferior, since the inferior will have stopped and
5422 will need to have its new stop-actions taken care of.
5424 * dbxread.c (read_struct_type): Expression gives Sun3 4.0.3
5425 compiler fits, simplify it.
5427 * gdb.texinfo (directory command): Doc new dir command.
5428 source.c (directory_command): "dir" now puts things on the front
5429 of the path, moves dups up front, and handles multiple names
5430 on the command line, inserting each one in order. It also
5431 blows away cached line and full_filename info.
5433 * stack.c (backtrace_command): Skip "more stack frames follow"
5436 * Change #ifndef HAVE_VPRINTF to #define MISSING_VPRINTF in
5437 xm-convex.h, xm-hp300bsd.h, xm-isi.h, xm-merlin.h, xm-news.h,
5438 xm-np1.h, xm-pn.h, xm-pyr.h, xm-symmetry.h, xm-umax.h, xm-vax.h.
5439 The only odd one was Gould NP1, which had defined vprintf to
5442 * Merge Ted Goldstein <tedg@Eng.sun.com>'s changes for epoch.
5443 printcmd.c (print_command_1): Pass 'inspect' flag down as a global
5444 variable, inspect_it.
5445 valprint.c (print_string, val_print): Use the global inspect_it
5446 to indicate whether to print in Epoch style or normal style.
5448 Mon Oct 1 23:55:26 1990 John Gilmore (gnu at cygint)
5450 * printcmd.c (call_command): add an alias for the "print" command
5451 which runs expressions and doesn't print the result if void.
5452 (print_command_1): implement it.
5454 * command.c: Remove #if 0'd code. Initialize all the fields
5455 in add_cmd (). Rename do_nothing_command to
5456 not_just_help_class_command, and make it externally visible.
5457 command.h: add user_commands to struct.
5458 * main.c (define_command): Don't overload c->function with a char
5459 string as well as a function pointer.
5461 * eval.c (evaluate_subexp): Reinstall tiemann changes to
5462 calling convention of value_struct_elt () that got dropped in
5465 * tm-sparc.h (FRAME_FIND_SAVED_REGS): move to sparc-xdep.c.
5466 sparc-tdep.c (sparc_frame_find_saved_regs): ditto.
5468 * tm-sparc.h (POP_FRAME): replace some constants with defines.
5470 * sparc-xdep.c (store_inferior_registers): defer stores to regs
5471 until a good time (e.g. when we are about to run the child),
5472 saving ptrace calls.
5473 * infrun.c (proceed): handle DO_DEFERRED_STORES.
5474 * tm-sparc.h: define DO_DEFERRED_STORES.
5476 * sparc-xdep.c (store_inferior_registers): when storing float
5477 registers, don't store stack regs too. When storing the SP,
5478 however, DO store the stack regs too. This fixes a bug in which
5479 the dummy frame is not recognized when a call_function finishes,
5480 because its frame pointer (in the stack regs) was never
5482 (read_inferior_registers): Mark WIM and TBR and FPS and CPS valid
5483 even though we don't know how to read them from an inferior.
5484 valops.c (call_function): Comment about storing SP.
5486 * infrun.c (save_inferior_status): Save away the original bpstat
5487 chain so it can be restored later. Install the copied version for
5488 use by whoever saved the status. It will be blow away by
5489 restore_inferior_status, and the original chain restored. This is
5490 important for people who have pointers into the original.
5492 * breakpoint.c, command.h, copying.awk, dbxread.c, defs.h,
5493 findvar.c, frame.h, obstack.h, obstack.c, inflow.c, value.h,
5494 main.c, printcmd.c, sparc-tdep.c, symtab.c, valprint.c: lint
5497 Fri Sep 28 20:32:46 1990 John Gilmore (gnu at cygnus.com)
5499 * Makefile.dist: Roll version to 3.91.8. Add bfd.h and bfdconfig.h
5500 temporarily to the makefile. Add am29k-opcode.h and WHATS.NEW.
5501 Add stuff.c and kdb-start.c to the OTHERS list for tar files.
5503 Fri Sep 28 19:12:12 1990 John Gilmore (gnu at cygint)
5505 * Merge Mike Tiemann's multiple inheritance changes from Sun.
5506 Store the baseclasses in a type struct starting from array element
5507 0 rather than from the unusual array element 1.
5509 dbxread.c: the above.
5510 (virtual_context): Add
5511 Read new debug information about which virtual function table
5512 a virtual function is from, and store it in fn_field.fcontext.
5514 symtab.h: Add fcontextt. Fix baseclass indices. Typo in
5515 TYPE_FN_FIELD_STATIC_P.
5517 symtab.c: the above.
5518 valops.c: the above. Handle pointer casts of object *'s.
5519 (search_struct_method): Add.
5520 (value_struct_elt): First arg is now a pointer to a value, and is
5523 valprint.c: the above.
5524 values.c (value_virtual_fn_field): Add type arg. Handle
5525 offsetting to the proper object when calling virtual fns.
5527 (baseclass_addr): Add valuep arg.
5529 * README: Document the current state of BFD config (missing).
5530 * TODO, ChangeLog, Makefile.dist: Roll version.
5531 * WHATS.NEW: Add summary of changes since 3.5.
5533 Thu Sep 27 16:23:12 1990 John Gilmore (gnu at cygint)
5535 * dbxread.c (read_struct_type): Clear bit vectors whenever
5537 symtab.c (B_CLRALL): define.
5539 * tm-sparc.h (STORE_RETURN_VALUE): Avoid clobbering types by
5540 using == rather than =. Huh... This fixes the dreaded problem
5541 wherein builtin_type_int becomes TYPE_CODE_FLT.
5543 * core.c (info_files): Show the inferior pid.
5545 * config.gdb: Avoid putting "dir" command into .gdbinit. GDB
5546 already knows how to look in the source directory.
5548 * Remove psymtab hair from many places. Remove duplicated code
5549 for searching symbol tables. Hide psymtabs from most places.
5550 Make it fast to get from a psymtab to its symtab.
5552 blockframe.c (blockvector_for_pc): Remove psymtab hair.
5553 coffread.c (psymtab_to_symtab): Rename to psymtab_to_symtab2.
5554 mipsread.c (psymtab_to_symtab): Rename to psymtab_to_symtab2.
5555 dbxread.c: export psymtab_to_symtab, make it work if called N times.
5556 (psymtab_to_symtab): Rename to psymtab_to_symtab2. Initialize
5557 new symtab completely. New psymtabs get symtab pointer
5558 initialized to zero. Remove MI warning printf.
5559 symtab.h: Comments. Add psymtab to symtab pointer.
5560 (PSYMTAB_TO_SYMTAB): New macro.
5561 symtab.c: use PSYMTAB_TO_SYMTAB. Add psymtab_to_symtab and export it.
5562 source.c: use PSYMTAB_TO_SYMTAB. Remove symtab version and
5564 stack.c (backtrace_command): Avoid pre-pass to read symbols, if
5566 (print_frame_info): Avoid special-casing symbols that have not yet
5569 * source.c (open_source_file): Quick path if we have already
5570 located the source file by its full name.
5572 * symtab.c (lookup_symbol): Use find_pc_symtab rather than
5573 find_pc_psymtab. When a name is found in the misc function
5574 vector, search the symbol table for its mangled name, not the
5575 name that the user typed.
5577 * bfd.h: Fix missing comment terminators, make #endifs match.
5579 * valarith.c (value_less): Handle unsigned int comparisons.
5580 Add FIXME about pointer compares, which assume host and target
5581 pointers are the same.
5583 * command.c (do_nothing_command): lint
5584 dbxread.c: lint. Remove sort_syms. Document C++ visibility info,
5585 fix comments on debug symbol format for visibility. Actually set
5586 visibility of symbols.
5587 main.c (echo_command): lint; use <readline/history.h>.
5588 tm-sparc.h (FRAME_FIND_SAVED_REGS): lint
5589 obstack.h (_obstack_blank): Rearrange pointer math to avoid
5590 pointing past end of allocated memory; saber complains.
5591 obstack.h: Declare the external functions that we use.
5592 valarith.h: use <string.h>
5593 solib.c (solib_add): lint.
5595 Fri Sep 21 17:05:19 1990 John Gilmore (gnu at cygint)
5597 * main.c (initialize_main): Default info_verbose to off, now that
5598 symbol reading is fast.
5599 (quit_command): Avoid clobbering exec_bfd while quitting.
5601 * Initial BFD (binary file diddling library) merger:
5602 coffread.c: Change AOUTHDR to struct exe_hdr.
5604 core.c: initialize initialized data at compile time.
5605 (core_file_command): Move from coredep.c, convert to bfd.
5606 (xfer_core_file): Convert to bfd.
5607 exec.c (exec_file_command): use bfd routines.
5609 mips-tdep.c: Remove exec_file_command and friends.
5612 * coredep.c: (fetch_core_registers) Convert core_file_command to
5613 fetch_core_registers.
5614 mips-xdep.c, sparc-xdep.c, sun3-xdep.c: ditto.
5616 * utils.c: (error): Bogus crap, FIXME, to print bfd errors.
5617 (my_bfd_read): More bogosity, which I don't think we call.
5618 (program_name): Remove this atrocity asap!
5620 Wed Sep 19 13:36:41 1990 John Gilmore (gnu at cygint)
5623 values.c: allocate_repeat_value was not clearing the
5624 optimized_out field.
5625 (value_static_field): minor stylistic fix (wrong macro was used).
5626 valops.c (value_struct_elt_for_address): didn't work for C++
5629 * signame.c (_initialize_signame): Initialize signal names once.
5631 * breakpoint.h, command.c, copying.awk, defs.h, environ.c,
5632 exec.c, frame.h, infcmd.c, inferior.h, main.c, munch, sun3-xdep.c,
5633 symtab.h, tm-29k.h, valprint.c, value.h, values.c: Lint.
5635 * remote-eb.c: Support user-settable baud rates on the serial port.
5637 * tm-sun3.h (PREPARE_TO_STORE): fix typo.
5639 Fri Sep 14 13:28:29 1990 John Gilmore (gnu at cygint)
5641 * tconfig/sun3os4: Remove warning about native assembler,
5642 since it also occurs in the xconfig file.
5644 * findvar.c (registers): Allocate some slop after `registers'
5645 to prevent stray accesses from trashing the next variable.
5647 * tm-68k.h (REGISTER_BYTES): Allocate the right number of bytes
5648 on the sun-3, by changing the #ifdef from `sun3' (which is not
5649 defined by cc) to `sun'. Symptom was trashed builtin_type_XXX
5650 vars, which happened to follow `registers' in the executable.
5652 * readline/history.c (history_search): Heed gcc-2's advice
5653 and parenthesize && inside ||).
5655 * am29k-opcode.h, am29k-pinsn.c, am29k-tdep.c, remote-eb.c,
5656 tm-29k.c: Insert FSF copyright headers.
5658 * remote-eb.c: Better comments.
5660 * Makefile.dist: Update to 3.91.6.
5661 * TODO: note PREPARE_TO_STORE problem.
5663 Thu Sep 13 09:52:33 1990 Jim Kingdon (kingdon at cygint)
5665 * stack.c (frame_info): Only use FRAME_FIND_SAVED_REGS if defined.
5667 * remote.c: Wrap the whole file in #if !defined (SPECIAL_REMOTE).
5669 * infrun.c (wait_for_inferior, at end): Don't set up
5670 prev_* if the inferior no longer exists.
5672 * inferior.h (CALL_DUMMY_LOCATION): New macro, to replace
5673 CANNOT_EXECUTE_STACK.
5674 valops.c (call_function): Use it.
5676 * tm-convex.h: Add CALL_DUMMY_LENGTH for use by PC_IN_CALL_DUMMY.
5678 * inferior.h (PC_IN_CALL_DUMMY): New macro.
5679 infrun.c (wait_for_inferior, 2 places): Use it.
5681 * values.c (value_being_returned): Only use
5682 EXTRACT_STRUCT_VALUE_ADDRESS if defined.
5684 * Move PREPARE_TO_STORE from xm-sun3.h to tm-sun3.h to do the
5685 right thing for remote-eb.c.
5687 * sun3-xdep.c: Remove extraneous call to remote_store_registers.
5688 * sun386-xdep.c, hp300hpux-xdep.c, sparc-xdep.c: Ditto.
5690 * blockframe.c: Put get_frame_saved_regs inside #if !defined
5691 (FRAME_FIND_SAVED_REGS).
5693 * findvar.c ({fetch,store}_registers): Check for
5694 REMOTE_{FETCH_STORE}_REGISTER macro.
5696 * findvar.c (get_saved_register): Add argument lval and
5697 change meaning of argument addr.
5698 findvar.c: Change calls to get_saved_register to reflect
5699 new calling convention.
5700 valops.c (value_assign): Use get_saved_register instead of
5701 find_saved_register.
5703 Sun Sep 2 12:40:20 1990 Jim Kingdon (kingdon at cygint.cygnus.com)
5705 * coffread.c (read_one_sym): Make temp_aux an AUXENT, not
5706 an (uninitialized) pointer to one. Use "&" when passing it
5709 Fri Aug 31 22:57:54 1990 Jim Kingdon (kingdon at cygint.cygnus.com)
5711 * coffread.c (getfilename): Use DGUX x_offset and x_name if
5714 * coffread.c (symbol_file_command): Put semicolon after
5716 Put safe_to_init_tdesc_context in #if defined (TDESC).
5717 Put #ifdef TDESCs in 1st column for non-ANSI cpp's.
5718 coffread.c: #include <sys/stat.h>.
5719 (read_coff_symtab): Typo: in_source_files -> in_source_file.
5720 Add missing ')' in check for "lc%" and friends. Remove
5722 Declare read_one_sym() at top of file.
5723 (read_file_hdr): Put in extra #ifdefs so MC68MAGIC and
5724 MC68WRMAGIC can have the same value without causing a duplicate
5727 Thu Sep 13 15:55:36 1990 John Gilmore (gnu at cygint)
5729 * Allow a Makefile to be built without building the
5730 tm and xm file links that screw up builds in subdirectories.
5731 This is done with `config.gdb none', then you can do things
5732 like `make gdb.tar.Z'.
5733 * tconfig/none: Config file for no target system
5734 * xconfig/none: Config file for no host system
5735 * config.gdb: If no TM or XM files are called out by the
5736 host or target file, don't make links for them.
5738 * cplus-dem.c: Add documentation.
5740 * dbxread.c (read_ofile_symtab): Turn a fatal error into a
5741 simple error, so the user's gdb doesn't crash due to some object
5742 file problem (e.g. somebody is rebuilding the file out from under
5745 * printcmd.c (print_address_symbolic): demangle the symbol.
5747 * Makefile.dist (OTHERS): Remove tdesc-lib because it has
5748 Motorola copyrights in it. Make "make gdb.tar.Z" work.
5749 (alldeps.mak): sort and uniq all results from this; duplicates
5750 hose gdb.tar.Z link building. Remove RCS files from
5751 tconfig and xconfig. Add config files for sun386. Add
5752 a few odd files to OTHERS and HFILES.
5754 Mon Sep 10 21:20:24 1990 John Gilmore (gnu at cygint)
5756 * Makefile.dist: Pull solib.c to tconfig/sun?os4.
5757 Roll version number to 3.91.5. Make lint work in bindir.
5759 * README: Document cross-debugging and new file structure.
5761 * blockframe.c: Lint. Include "value.h" to declare read_register.
5762 (find_pc_partial_function): remove duplicate line.
5764 * command.h: Lint. Declare error_no_arg and dont_repeat.
5766 * tm-news.h: Remove inadvertently duplicated stuff.
5768 * mipsread.c: Remove cache_pc_function stuff, now done cleanly.
5769 Clean up usage of misc_function_type. Declare some CORE_ADDRs.
5771 * config.gdb: Allow `config.gdb host target' form. Clean
5772 up previous change that printed bogus messages when you just said
5775 * core.c: #include "command.h" for lint.
5778 * main.c: Remove some casts of enums. Lint.
5785 * printcmd.c (initialize_printcmd): Fix thinko in inspect cmd.
5787 * sparc-tdep.c (isannulled): Take instruction as parameter, don't
5788 read it from memory. This will allow us to save ptrace calls
5789 eventually. Changed caller single_step too.
5791 * sparc-xdep.c (fetch_inferior_registers): Avoid reading regs
5792 that we aren't going to use, saving many ptrace calls, especially
5793 when watchpointing or single stepping. Use some #define's for
5795 (store_inferior_registers): Ditto.
5796 (core_file_command): Use some #define's for constants.
5798 * tm-sparc.h: Add #define's for some register numbers, so we
5799 can eliminate the use of random constants in sparc-xdep.c.
5801 * stack.c (frame_command, print_frame_info, up_command,
5802 down_command) Remove frame_changed, since it
5803 causes a bug and doesn't seem to do anything useful. In some
5804 places it was used as a flag, in others as a stack level (?).
5806 * utils.c: Use MISSING_VPRINTF rather than HAVE_VPRINTF, so the
5807 default is to use the portable (vprintf) version rather than the
5809 * xm-news.h (MISSING_VPRINTF): Add.
5811 * valprint.c (val_print): Demangle fancy vtbl printouts. Lint.
5813 Sat Sep 8 00:24:12 1990 John Gilmore (gnu at cygint)
5815 * Remove stuff that forces -Bstatic linking of gdb, and warnings
5816 about linking debugged programs -Bstatic in the sun?os4 config
5817 files in tconfig and xconfig subdirectories.
5819 * main.c (main): Remove unreached exit(0) now that we exit
5822 * Create TODO file for online bug list. There are too many
5823 "little" bugs to keep track of on paper.
5825 * Change Projects file to refer to bug-gdb@cygnus.com
5826 rather than kingdon@ai.
5828 Fri Sep 7 23:35:15 1990 John Gilmore (gnu at cygint)
5830 * Makefile.dist (VERSION): 3.91.4 now.
5832 * symtab.c (init_misc_bunches): Rename from init_misc_functions.
5833 (condense_misc_bunches): Add sanity check that misc_count is
5834 the same as the number of symbols in the bunch.
5836 * coffread.c: rename init_misc_bunches. Pass an argument
5837 to condense_misc_bunches (a zero).
5839 * dbxread.c (partial_symbol_file_read): Call init_misc_bunches
5840 every time we are called; don't rely on our caller to do it.
5841 (add_file): Remove call to init_misc_bunches.
5843 * mipsread.c: Only warn, don't error, if unknown symbol types.
5844 This keeps an old gdb from falling on its face if it sees newly
5845 extended symbol info. Rename init_misc_bunches.
5847 Fri Sep 7 22:58:15 1990 John Gilmore (gnu at cygint)
5849 * Merge in changes from Per Bothner for DECstations and other
5850 MIPS stuff. The rest is Bothner speaking:
5852 The next message is a merger of Alessando Forin's mips port with
5853 mine. I've tried to use my good if biased judgment to get
5854 the best of both. It *does* need testing.
5856 Some of the changes are general, *not* mips-specific.
5859 Didn't believe in little-endian bit order.
5860 There are still inconsistencies about whether flags
5861 like BITS_BIG_ENDIAN are integer (#if ...) or
5862 boolean (#ifdef ...). I tried to paper over them.
5864 dbxread.c,coffread.c,mipsread.c,symtab.c,symtab.h:
5865 Moved some misc_function code that was common to
5866 {dbx,coff,mips}read.c to symtab.c.
5867 In the process, I think I cleaned things up a bit.
5868 At the same time, moved obsavestring and obconcat to symtab.c.
5871 Removed obsolete condense_addl_misc_bunches (use
5872 condense_misc_bunches(1) instead).
5875 Needed to include <sys/dir>, at least on DECstations.
5877 valops.c, mips-tdep.c, tm-mips.h:
5878 Added PUSH_ARGUMENTS macro to support funny argument-pushing
5879 conventions (when STACK_ALIGN is insufficient).
5880 Needed on mips, where doubles need 8-byte alignment,
5881 but ints only need 4.
5884 Removed cruft that was not being used.
5885 Merged in many fixes (most from Frank Yellin, fy@lucid.com).
5888 Print $ before register-names (I think that makes things a little
5890 Never print two instructions, even if one delays.
5891 Removed hex-disassemble set_cmd. (This is not mips-specific,
5892 so I think the argument is whether it is generally worthwhile or not.
5893 I'm inclined to think not, given how easy it is to
5894 convert between radixes in gdb.)
5897 This is basically Alessando's code.
5898 It doesn't use obstacks; I changed it to use obstacks
5899 in a few minor places where using malloc causes a
5900 memory leak. (Probably, more places could/should be changed.)
5901 I added record_misc_function where it was missing.
5902 In symbol_file_command and add_file_command, I tried
5903 to make the code consistent with more recent versions.
5904 Minor sylistic changes in parse_procedure.
5905 Make a .gdbinfo. psuedo-symbol point back to the real
5906 procedure symbol (using the isym field).
5909 This is basically from my port, but with a lot of details
5910 and a number of routines merged in from Alessando's version.
5911 I basically used my code "raw" backtrace (use heuristics
5912 from the actual code, rather than symbol table info) - though
5913 the idea is Alessandro's. I feel my code is a little cleaner
5914 here, particularly in being a little more flexible, such as being
5915 able to handle gcc-produced code (which it now can).
5916 It also doesn't do frame caching (which is not useful
5917 more recent gdb versions).
5918 I also used my code for push_/pop_dummy, more or less.
5919 I tried to incorporate AF's code for testing sigtramp
5920 while backtracing; I probably got it wrong.
5921 Added mips_print_register, which tries to scrunch as much
5922 information as possible on a screen...
5923 Removed the skip-prologue set_cmd. As with hex-disassemble (see
5924 under mips-pinsn.c), I don't see anything mips-specific here,
5925 and I don't see it being all that useful anyway.
5928 Added a $fp psuedo-reg distinct from $fp (nice for gcc).
5929 Use more register names (rather than hard-cases numbers).
5931 Thu Sep 6 18:33:15 1990 John Gilmore (gnu at cygint)
5933 * Hack up 3.90.11 changes:
5935 * Makefile.dist (depend): parameterize $(GCC).
5936 Add solib.c and solib.o.
5937 (readline): Fix vpath for both absolute or relative SRCDIR.
5939 * blockframe.c: Fix from Schaefer@asc.slb.com for shared libs.
5940 Also, let the part I didn't understand at least compile so
5941 I can test the rest. FIXME.
5943 * dbxread.c: Fix thinko using strcmp.
5944 (init_psymbol_list): declare static.
5945 (partial_symbol_file_open): Comment cleanups better, avoid
5946 cleaning up the string table since the caller will do that.
5947 Move the stat for mod time into symbol_file_command, temporarily.
5948 (There should be a mod time for each symbol file, eventually,
5949 to control its rereading. FIXME.)
5951 * infptrace.c (PT_WRITE_D): use same value as PT_WRITE_I for
5952 SunOS, which gives error for shared libs otherwise. (From
5953 Schaefer, probably FIXME needs work for portability.)
5955 * solib.c: Move #include "param.h" to work.
5956 Lowercase all the Uppercase Letters In the Messages.
5957 (find_solib): Clean up inferior_so_name for debug printouts.
5958 Allow no argument, to mean all shared libraries.
5960 * symmisc.c: include param.h to get CLEAR_SOLIB.
5962 Wed Sep 5 18:00:08 1990 John Gilmore (gnu at cygint)
5964 * Merge in Kingdon's changes from FSF: the diffs from 3.90.9
5965 to 3.90.11. ChangeLog entries below are from this.
5967 Wed Jun 13 09:17:39 1990 Jim Kingdon (kingdon at mole.ai.mit.edu)
5971 * Makefile.dist (HFILES): Add tm-sunos.h.
5973 Tue Jun 12 16:15:26 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5977 * Makefile.dist (gdb.tar.Z): Change linking of config so it works.
5979 Thu Jun 7 16:22:27 EDT 1990 Jay Fenlason (hack@ai.mit.edu)
5981 * sparc-opcode.h Added single-operand version of rett.
5983 Mon Jun 4 18:12:31 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5985 * m-sparc.h (REG_STRUCT_HAS_ADDR, STRUCT_ARG_SYM_GARBAGE):
5986 Put parens around gcc_p in expansion.
5988 Thu May 24 15:44:51 1990 Jim Kingdon (kingdon at mole.ai.mit.edu)
5990 * utils.c (lines_to_list): Return 10 if lines_per_page == 0.
5992 Wed May 23 16:36:04 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5994 * Changes for Sun shared libraries:
5995 blockframe.c (find_pc_partial_function): If a non-text symbol
5996 is found, set *address = pc - FUNCTION_START_OFFSET.
5997 breakpoint.c (insert_breakpoints) [DISABLE_UNSETTABLE_BREAK]:
5998 Disable breakpoints instead of giving an error.
5999 source.c (select_source_symtab): Initialize cs_pst.
6000 symmisc.c: Call CLEAR_SOLIB if defined.
6001 symtab.h: Make text{low,high} CORE_ADDR not int.
6002 (psymtab): New field addr.
6004 dbxread.c: Move DECLARE_FILE_HEADERS outside functions.
6005 (record_misc_function): Give correct type for N_DATA symbols.
6006 (condense_misc_bunches): do "misc_function_count = j" regardless
6008 Take code which is shared between symbol_file_command and
6009 add_file_command and put it into partial_symbol_file_{open,read}.
6010 Split add_file_command into add_file_command and add_file.
6011 Make psymtab_to_symtab read in the string table if the file
6013 Two new parameters to read_dbx_symtab and start_psymtab.
6014 tm-sunos.h: New file.
6016 Tue May 22 17:43:03 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
6018 * infcmd.c: Change cont_command to continue_command and "cont"
6021 Mon May 21 14:41:41 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
6023 * breakpoint.c (enable_breakpoint): Get value of watchpoint.
6025 * defs.h [sparc]: Use <alloca.h> regardless of __GNUC__.
6027 * values.c (USE_STRUCT_CONVENTION): Check for structures of
6028 size 1,2,4,8 rather than size < 8.
6030 * dbxread.c (dbx_lookup_type): Do f->length *= 2 as many times
6031 as necessary, not just once.
6033 * sparc-opcode.h: Add a bunch of new opcodes which Sun as supports.
6035 Thu May 17 15:04:09 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
6037 * {t,x}m-sun386.h, sun386-xdep.c, {x,t}config/sun386
6039 * tm-news.h: Add CALL_DUMMY_*.
6041 * tm-68k.h: Remove duplicate comment at FRAME_FIND_SAVED_REGS.
6043 * config.gdb: In list_host, list_target, use ${i}, not $i.
6045 Tue May 15 21:27:12 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
6047 * source.c (find_source_lines) [BROKEN_LARGE_ALLOCA]: Use xmalloc.
6049 * sparc-opcode.h: Change all store floating-point state register
6050 instructions to have the right match & lose fields.
6052 Sat May 5 12:39:18 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
6054 * Makefile.dist: Move -I${srcdir} to GLOBAL_CFLAGS and pass
6056 config.gdb: If srcdir != ., create readline directory and
6057 copy a makefile into it.
6059 * wait.h, infrun.c: Change WRETCODE to WEXITSTATUS for
6060 consistency with POSIX.
6062 * breakpoint.c (bpstat_stop_status): Disable watchpoint
6063 when we exit its exp_valid_block.
6065 Tue Sep 4 11:46:46 1990 John Gilmore (gnu at cygint)
6067 * Makefile.dist: Bump version to 3.91.3.
6069 * Clean up handling of breakpoint commands (somewhat).
6070 Prompted by Tiemann bug report "cont 10" doesn't work any more.
6072 inferior.h: Add breakpoint_proceeded to inferior status struct
6073 and globals; save it and restore it.
6074 (clear_breakpoint_commands): Cleanup, remove old #define.
6076 infrun.c (clear_proceed_status): Set breakpoint_proceeded.
6077 (save_inferior_status, restore_inferior_status): handle it also.
6078 (proceed): Remove earlier code that set breakpoint_proceeded.
6079 It is now set only in clear_proceed_status.
6080 (clear_proceed_status): Cleanup, use bpstat_clear rather
6081 than clear_breakpoint_commands. No callers need the stop_bpstat
6082 between clear_proceed_status and proceed.
6084 infcmd.c: Add breakpoint_proceeded definition and comment.
6085 (cont_command, jump_command, signal_command): Move call to
6086 clear_proceed_status right next to call to proceed.
6088 breakpoint.c (bpstat_do_actions): Avoid clobbering our
6089 caller's argument while running down the chain of breakpoints.
6090 Use new variable "breakpoint_proceeded" to determine when
6091 a command that it executes moves the inferior past the
6093 (bpstat_clear): Handle NULL argument.
6094 (bpstat_clear_actions): Avoid useless call to
6095 breakpoint_auto_delete.
6096 (delete_breakpoint): Clean up bpstat's that are pointing to
6097 the deleted breakpoint from the stop_bpstat chain.
6098 (breakpoint_auto_delete): Simplify.
6100 * Clean up handling of EOF, error on stdin, etc. This was
6101 prompted by a network problem that caused gdb to go into an
6102 infinite loop filling up its malloc'd memory.
6104 main.c (return_to_top_level): Cleanup: call bpstat_clear_actions,
6105 not clear_breakpoints_commands, which is now gone.
6106 (main): If command_loop returns (e.g. from EOF on stdin), do
6107 a quit_command (looping back to command_loop if quit_command
6108 doesn't really quit).
6109 (command_loop): check result from command_line_input and
6110 exit if it returns NULL, rather than passing the NULL to
6112 (gdb_readline): Free malloc'd result space before returning
6115 * utils.c (query): Handle C-d to mean "yes", just as if the
6116 input was not a terminal. Also avoid infinite loop if EOF
6117 occurs in mid-input-line before newline. This allows
6118 query to be used at EOF on stdin with reasonable results.
6120 * infrun.c (proceed): Set breakpoint_proceeded.
6122 * values.c (value_as_long): Avoid infinite recursion for enums.
6123 (_initialize_values): Fix typo in help msg (kingdon).
6125 * Makefile.dist (RL_LIB): Use RL_LIB_DEP for dependencies,
6126 RL_LIB for linking. This allows -lreadline for linking
6127 and nothing for dependencies, once readline is a real library.
6129 * config.gdb: Jim Kingdon: give useful error message if the
6130 host or target type is not recognized.
6132 * defs.h (alloca): SPARC <alloca.h> does not declare alloca,
6133 it just defines it. Dumb, but deal with it.
6135 * Jim Kingdon suggests:
6136 in xconfig/sun3os4, CFLAGS should be XM_CFLAGS.
6138 Wed Aug 29 18:03:27 1990 John Gilmore (gnu at cygint)
6140 * Makefile.dist (VERSION): Bump version # to 3.91.2.
6142 * Clean up Bothner's changes.
6144 * blockframe.c (clear_pc_function_cache): New function.
6145 * blockframe.c: remake cache_pc_function_* static.
6146 * dbxread.c (symbol_file_command): remove references to
6147 cache_pc_function_* variables.
6148 * dbxread.c (read_struct_type): Use VOFFSET_STATIC.
6149 * printcmd.c: Avoid kludging a global variable (addressprint)
6150 to avoid printing the address of a string twice. Instead,
6151 pass the format letter 's' down low enough that it can be seen
6152 to avoid this problem.
6153 (print_formatted): Pass format arg to value_print.
6154 (restore_addressprint): Remove function.
6155 (do_examine): Avoid hacking addressprint, cleanups and such.
6156 (print_frame_args): Add a comment to a Bothner change.
6157 * symtab.h: define VOFFSET_STATIC and use it instead of "-1".
6158 * symmisc.c (free_all_symtabs): Call clear_pc_function_cache
6159 to wipe out the values cached in blockframe.c.
6160 * symtab.c (find_method): Add comment saying how big you must
6161 allocate to be "big enough". Per being terse again.
6162 * valprint.c (val_print): Handle format letter "s" to print
6163 strings without addresses. Add comment to vtbl printing code
6164 which casts with wild abandon. Rearrange reference-printing
6166 @0xaddr: value (print w/addressprint)
6167 value (print w/~addressprint)
6168 @0xaddr (parameter lists w/addressprint)
6169 or nothing (parameter lists w/o addressprint)
6171 Tue Aug 28 10:47:18 1990 John Gilmore (gnu at cygint)
6173 * Merge more changes from Per Bothner:
6175 Gdb's handling of TYPE_CODE_REF was so counter-C++ (and otherwise
6176 annoying) that I tried to improve it. Here are my suggestions.
6178 These patches all attempt to handle TYPE_CODE_REF (as in C++) better.
6181 Do automatic de-reference when taking the address of a reference.
6183 Don't deref_ref when printing parameter lists.
6185 More attempts at treating refernences properly.
6187 In val_print, if deref_ref==0, don't print dangling " = ".
6189 Add COERCE_REF macro, which de-references an REF.
6191 * Merge changes from Per Bothner:
6193 * Fixed (Sony news)-specific configuration problems.
6194 * Fixed other problems with using vanilla pcc and libc (enum problems;
6195 assumption that vsprintf exists).
6196 * Some major speed-ups (finc_pc_partial_function now caches a match;
6197 parsing avoids duplicate symbol_lookup calls).
6198 * Changed handling of baseclasses (no longer use baseclasses field
6199 of struct type, use the first n_baseclasses fields instead).
6200 * Various minor changes/fixes, most C++-related.
6203 Cache the most previous match from find_pc_partial_function.
6204 (Save both low and high ends of matching function's pc range.)
6205 This speeds up the loop of infrun.c:wait_for_inferior quite
6206 a bit, and makes step/next commands much zippier.
6208 Added an enum->int cast (otherwise, some compilers barf).
6210 No longer set baseclass offset to 0, since multiple
6211 inheritance now mostly works.
6212 Added a number of casts, to shut up compiler warnings
6213 (after stabs where made enums, not ints).
6214 When discarding a symbol table (in symbol_file_command),
6215 must clear the cache introduced in blockframe.c.
6216 Don't convert $vtbl_ptr_type to vtbl any more.
6217 Get rid of TYPE_BASECLASEES and baseclass_vec (see also symtab.h).
6218 Mask off sign bit emitted by g++ for virtual table offset.
6219 Set voffset to -1 (not 1) for static member functions.
6221 Changed parsing/lexing of names to avoid doing symbol lookup twice
6222 (once when lexing to determine symbol class, once for real).
6223 Now only call symbol_lookup once. Fields of 'this' win especially big.
6225 Subpress printing addr twice in the case of 'x/s addr'.
6227 lookup_basetype_type is no longer used.
6228 Add find_methods as recursive helper function to decode_line_1.
6229 This allows multiple inheritance to work.
6230 Also, once one or more matches has been found, do not look in
6231 base-classes. (Baseclass methods would be overridden, anyway.)
6233 Removed baseclasses array in struct type.
6234 Instead of using baseclasses[i], use fields[i-1].
6235 Added virtual_field_bits[i] to indicate if the i'th baseclass is virtual.
6236 Changed sign convention of voffset (previous was inconsistent).
6238 Some macros (CALL_DUMMY and relatives) were missing. Put them back.
6240 Used to assume existence of vsprintf. Re-written to not need it
6241 if HAVE_VPRINTF is undefined.
6243 typecmp was too pessimistic. Made it less so.
6245 Don't print space after address.
6246 If vtable points to a misc symbol (with 0 offset), print it,
6247 since that indicates the actual class of the object.
6248 Changed ype_print_derivation_info to use new inheritance
6249 scheme (without baseclasses vector).
6251 In value_primitive_field, fixed some bugs left over from previous set of fixes.
6252 Also, changes needed because TYPE_BASECLASSES were removed.
6254 REGISTER_U_ADDR didn't work for PC. Rewrote to use an array.
6256 Tue Aug 21 20:08:54 1990 John Gilmore (gnu at cygint)
6259 If there is no path set, and the symbols don't indicate what directory
6260 a file was compiled in, look in the current directory. But either
6261 a path or a known compilation directory will prevent this.
6264 Three independent bug fixes:
6265 * Remove the #if 0 block that breaks some stuff.
6266 * SunOS 4.1 fixed the promoted-parameter-wrong-addr bug in Sun C;
6267 adapt gdb to either SunOS 4.0.* or 4.1.
6268 * MAX_OF_TYPE and MIN_OF_TYPE thinko. By tedg@sun, I think.
6271 Instantiate the class T when looking for methods in it. (Tiemann@sun)
6274 (type_print) Demangle the name being printed.
6275 (type_print_base) Handle botched demangling without coredump (tiemann).
6278 (check_stub_method): Document routine.
6279 (tiemann) fix bug for no-arg functions
6280 Avoid clobbering beyond end of malloc'd storage.
6281 Terminate the argument list properly.
6283 Sat Aug 18 01:29:59 1990 Per Bothner (bothner@cs.wisc.edu)
6285 * Changes merged by John Gilmore:
6288 In breakpoint_1, use new print_address_symbolic instead
6289 of find_pc_partial_function. (This forces use of assembler-level
6290 addresses, and avoids misleading non-mangled source-level names.)
6292 Generalize ansi argument such that -1 means skip arglist totally.
6293 Removed global variable print_ansi_qualifiers (which made
6294 code non-reentrant), in favor of extra explicit arguments
6295 to internal routines.
6297 Add new helper function print_address_symbolic.
6298 Use find_pc_misc_function instead of find_pc_partial_function
6299 (since we want assembler-level symbols here).
6301 Print unknown function as just "f (...)", not "f (...) (...)".
6302 Use new fputs_demangled explicitly.
6304 Fixed a typing violation (problem: value.h cannot be imported
6305 without renaming many variable in this file).
6306 lookup_symbol: If no matching misc_func, look for a C++-mangled name.
6307 decode_line_1: Moved forward some never-reached code.
6308 Made decode_line_2 skip function prologues correctly.
6310 fputs_filtered should not demangle by default.
6311 Add new fputs_demangled to demangle on demand..
6313 Change value_struct_elt to use value_primitive_field (using recursive
6314 utility function search_struct_field). This allows foo.bar to work
6315 for multiple inheritance (so far only for data fields).
6316 Change check_field in the same way (recursive helper function
6317 to support multiple inheritance).
6318 (Note: there are more of these problems that I haven't fixed.
6319 Any code that says TYPE_BASECLASS (t, 1) is probably wrong.)
6320 value_of_this: 'this' symbol name is now just "this", note "$this".
6322 Don't print static members.
6323 Avoid printing "members of <type>" if there are none.
6324 Simplified type_print_derivation_info by merging duplicate code.
6325 Remove useless blank lines in type_print_base (ptype command).
6327 Added declaration of new routine value_primitive_field.
6329 Added value_primitive_field which is generalized version of
6330 value_field that can handle multiple inheritance (non-zero offsets etc).
6331 Re-implemented value_field to call value_primitive_field.
6333 Fri Aug 17 23:33:44 1990 John Gilmore (gnu at cygint)
6335 * infcmd.c -- insert else to avoid 'delete env' coredump when you
6336 delete the whole environment. Karl Berry reported the bug.
6337 * source.c - fix openp to avoid //'s in filenames, which
6338 trigger an Emacs bug causing it to not be able to find files
6339 when running gdb in a window.
6340 * dbxread.c - zap the #if 0 that botches the add-file code.
6341 It seems to work a lot better without all the code commented out.
6343 Fri Jul 20 16:58:46 1990 John Gilmore (gnu at cygnus.com)
6345 * Merge Tiemann's and Ted Goldstein's changes, detailed below,
6348 Tue Jul 17 19:34:33 1990 Ted Goldstein (tedg at golem)
6350 * Makefile - added a ${CFLAGS} to a couple of entries,
6351 added remote-sa.sparc.c
6352 * added remote.sa-sparc.c, a modification of remote.c
6353 which conducts a dialog directly with the SparcStation prom.
6354 * breakpoint.c, infrun.c, sparcdep.c added
6355 remote_insert_breakpoint(), and remote_remove_breakpoint()
6356 to breakpoint.c instead of directly writing breakpoint instructions.
6357 * sparcdep.c on remote_debugging,there is no need
6358 to remove signle step breakpoint instructions.
6359 * main.c added "-epoch" flag and "int epoch_interface" to main.c
6361 * printcmd.c - epoch interface sends lisp expressions to open up
6362 epoch windows on inspection.
6363 * valprint.c - added arrayprint, and addressprint and made adding
6364 format controls easier
6365 * wait.h added a couple of undef's because we were getting
6366 complaints about WSTOPSIG and WTERMSIG begin redefined.
6369 Wed Jul 4 05:27:51 1990 Michael Tiemann (tiemann at masham)
6371 * symtab.c (decode_line_1): Add support for handling method stubs
6372 in the type information.
6374 Tue Jul 3 09:39:18 1990 Michael Tiemann (tiemann at masham)
6376 * values.c (baseclass_addr): Run loop from INDEX+1 to
6377 N_BASECLASSES; otherwise, we can still get into a loop.
6378 @@ This should be restructured to use a cleaner search strategy.
6380 Sun Jul 1 12:28:51 1990 Michael Tiemann (tiemann at masham)
6382 * dbxread.c (define_symbol,read_type): Grok GNU C++'s new
6383 abbreviation "Tt" for tags which have the same name as their
6386 Fri Jun 29 01:03:46 1990 Michael Tiemann (tiemann at masham)
6388 * symtab.c (list_symbols): add ability to set breakpoints on all
6389 the functions which match a particular regular expression.
6391 Tue Jun 26 04:26:29 1990 Michael Tiemann (tiemann at masham)
