[binutils-gdb.git] / gdb / ChangeLog
1 Fri Nov 22 08:27:40 1991 John Gilmore (gnu at cygnus.com)
2
3 * buildsym.c, coredep.c, mem-break.c, xcoffread.c: Put <stdio.h>
4 first, before defs.h.
5 * config/mh-i386sco: Override compiler to gcc, print warning.
6 * configure.in: Handle i386-none-aout rather than i386-aout-none.
7 * infptrace.c, language.h, utils.c: Lint.
8 * m2-exp.y: #undef MAX and MIN in case system includes set them.
9 * xm-tahoe.h: Set HOST_BYTE_ORDER. Include system versions of
10 {BIG,LITTLE}_ENDIAN and the INT_MAX family first, to avoid
11 redefinition warnings.
12 * defs.h: Reorder things so that the xm-file gets first crack
13 at #define's, followed by defs.h and then the tm-file.
14 * Makefile.in: Remove spaces after 'ignore exit code' - flags.
15 Late-model BSD 'make's don't cope with them.
16
17 Thu Nov 21 23:48:56 1991 John Gilmore (gnu at cygnus.com)
18
19 * Makefile.in: Roll new files into various lists.
20
21 Thu Nov 21 18:26:11 1991 Fred Fish (fnf at cygnus.com)
22
23 * dwarfread.c (struct_type): Must initialize the c++ specific
24 portion of union types as well as struct types, since gdb attempts
25 to reference the c++ specific info for both types.
26
27 Thu Nov 21 10:23:52 1991 John Gilmore (gnu at cygnus.com)
28
29 * Makefile.in: Roll VERSION to 4.2.90.
30
31 * defs.h: Incorporate param.h into defs.h. All users changed.
32 * param-no-tm.h: Change users to define TM_FILE_OVERRIDE instead.
33 * param.h, param-no-tm.h: Removed.
34 * Update copyrights in all changed files.
35 * dbxread.c, dwarfread.c, inflow.c, infrun.c, m2-exp.y, putenv.c,
36 solib.c, symtab.h, tm-umax.h, valprint.c: Lint.
37 * tm-convex.h, tm-hp300hpux.h, tm-merlin.h, tm-sparc.h,
38 xm-merlin.h: Avoid host include files in target descriptions.
39 * getpagesize.h: Removed, libiberty copes now.
40 * Makefile.in: Remove getpagesize.h, param.h, param-no-tm.h.
41
42 * exec.c (exec_files_info): If `verbose' is set, show file offset
43 as well.
44
45 * main.c: Use getcwd rather than getwd.
46 * standalone.c: Fake getcwd rather than getwd.
47 * xm-*.h: Remove fake values of MAXPATHLEN.
48
49 * xcoffexec.c: Add /* */ to #if 0'd thing to help ANSI.
50
51 Wed Nov 20 18:35:56 1991 John Gilmore (gnu at cygnus.com)
52
53 * Remove gdb/hp-include. Support for HP a.out oddities should be
54 in BFD, not in GDB. Move gdb/hp-include/a.out.h to include/a.out.hp.h.
55
56 * infptrace.c, tm-sun386.h: Cashier <a.out.gnu.h>, remove refs.
57
58 * configure.in, xconfig, tconfig, Makefile.in, doc/gdbint.texinfo:
59 Makefile fragments for various hosts and targets now come from
60 gdb/config/mh-* and gdb/config/mt-*. This is for consistency with
61 other config setups.
62
63 * rs6000-pinsn.c, rs6k-opcode.h: Clean up.
64 * rs6k-opcode.def: Delete.
65
66 Wed Nov 20 05:04:40 1991 Fred Fish (fnf at cygnus.com)
67
68 * dwarfread.c: Recognize obsolete form of AT_element_list
69 attribute still used by at least one AT&T compiler, and possibly
70 more.
71
72 Tue Nov 19 07:53:55 1991 Fred Fish (fnf at cygnus.com)
73
74 * dwarfread.c (enum_type, struct_type): Ignore names invented by
75 helpful compilers for anonymous structs, unions, and enums.
76
77 * c-exp.y, m2-exp.y: Add defines for yymaxdepth, yy_yys, and
78 yy_yyv, so multiple parsers produced by SVR4 versions of yacc
79 can coexist in the same executable without collision.
80
81 * symtab.h: Add declaration for lookup_template_type() to kill
82 compiler warnings about conversions from int to pointer.
83
84 Mon Nov 18 17:45:18 1991 Fred Fish (fnf at cygnus.com)
85
86 * procfs.c: Move inclusion of defs.h to before param.h, as in
87 all the other source files that include both. This is required
88 to supply some typedefs that are used in files included by param.h.
89
90 * m68k-tdep.c (m68k_skip_prologue): Add generic m68k support for
91 skipping function prologues, ala the other cpu families (i386,
92 mips, m88k, etc). Add the ability to skip movm and fmovm
93 instructions in the prologues. Still needs support for profile
94 (-p compiled) prologue sequences (FIXME).
95
96 * tm-68k.h: Change SKIP_PROLOGUE macro to use the new generic
97 m68k prologue skipping function by default.
98
99 * tm-altos.h, tm-isi.h: Continue to use the old definition of
100 SKIP_PROLOGUE.
101
102 Mon Nov 18 15:12:45 1991 John Gilmore (gnu at cygnus.com)
103
104 * Makefile.in: Remove tdesc stuff, and extra blanks before colons.
105 * blockframe.c: Remove tdesc-related code. Default
106 FRAME_CHAIN_COMBINE.
107 * infrun.c: Remove tdesc-related code.
108 * m88k-tdep.c (frame_chain_combine, init_frame_pc): Remove copies
109 of defaultable things.
110 * tm-m88k.h: New file, common to all Moto 88k target configs.
111 Derived from tm-delta88.h.
112 * tm-delta88.h: Use it.
113 * xm-m88k.h: Common file for 88K hosts. Remove obsolete stuff.
114 * xm-delta88.h: Use it.
115 * tm-*.h: Remove FRAME_CHAIN_COMBINE macros, since all are
116 default.
117 * coffread.c: Remove tdesc stuff.
118 * tconfig/delta88, tconfig/m88k: Remove tdesc stuff.
119 * xconfig/m88k: Rename tm-88k.h to tm-m88k.h.
120
121 Mon Nov 18 13:51:37 1991 Per Bothner (bothner at cygnus.com)
122
123 * source.c (open_source_file): If openp fails, try again
124 using just the base (non-directory) part of the filename.
125 This solves various annoying problems, such as when the
126 source was compiled with an absolute pathname - and the
127 source files have moved. Or if the source was compiled
128 using a relative pathname, it can be more convenient
129 to just specific the source directory to the dir command.
130
131 Mon Nov 18 00:04:41 1991 Fred Fish (fnf at cygnus.com)
132
133 * cplus-dem.c (munge_function_name): Add missing third arg to
134 instance of call to do_type().
135
136 * dwarfread.c: Changes to match new dwarf.h. Remove
137 AT_deriv_list, AT_loclist, AT_incomplete, AT_const_data,
138 and AT_is_external.
139
140 Sun Nov 17 16:20:53 1991 Michael Tiemann (tiemann at rtl.cygnus.com)
141
142 * symtab.h (struct type): Moved C++-specific fields into new type
143 `struct cplus_struct_type'. Now takes 10% less memory. Many
144 macros changed.
145 * symtab.c (init_type): Don't set fields belonging to
146 TYPE_CPLUS_SPECIFIC unless TYPE is TYPE_CODE_STRUCT.
147 * buildsym.c (read_type): Allocate TYPE_CPLUS_SPECIFIC for
148 TYPE_CODE_STRUCT.
149 (read_struct_type): Ditto. Also, add comments about how we can
150 deduce TYPE_VPTR_FIELDNO from inheritance info and fieldname info.
151 * coffread.c (decode_base_type): Allocate TYPE_CPLUS_SPECIFIC for
152 TYPE_CODE_STRUCT.
153 (read_struct_type): Ditto.
154 * dwarfread.c (struct_type): Ditto.
155
156 * symtab.c (read_range_type): Don't set TYPE_MAIN_VARIANT.
157 (lookup_pointer_type): Don't use or set TYPE_MAIN_VARIANT.
158 (lookup_reference_type): Ditto.
159
160 * cplus-dem.c: Many changes made to handle decoding of
161 ANSI-mangled names.
162 * symtab.c (gdb_mangle_name): Mangle/demangle ANSI-mangled names
163 as well.
164
165 Fri Nov 15 17:57:59 1991 Stu Grossman (grossman at cygnus.com)
166
167 * mipsread.c (parse_partial_symbols): patch to keep DEC C
168 compiler from making gdb bomb out. Thanks to Ed Santiago!

170 Thu Nov 14 19:27:30 1991 Fred Fish (fnf at cygnus.com)
171
172 * symfile.c: Add function compact_misc_function_vector() to
173 remove duplicate misc function vector entries. See comments
174 in source for why this is necessary/desirable.
175
176 * dwarfread.c: Add misc function type parameter to internal
177 record_misc_function(). Remove calls to init_misc_bunches()
178 and condense_misc_bunches(), these are now done in elfread.c.
179
180 * elfread.c: Add support for reading bfd canonical symbol tables
181 and generating misc function vector entries for global and
182 absolute symbols. Do calls to init_misc_bunches() and
183 condense_misc_bunches() where they will enclose all calls to
184 record_misc_function(), including those in dwarfread.c.
185
186 Thu Nov 14 17:02:11 1991 Roland H. Pesch (pesch at cygnus.com)
187
188 * doc/Makefile.in: new targets gdb.me, gdb.ms, gdb.mm
189 (roffable documentation).

198 of Nov 12th.
199
200 Wed Nov 13 19:51:11 1991 Steve Chamberlain (sac at cygnus.com)

206
207 Motorola 88000 port without tears, I mean without tdescs.
208
209 * m88k-tdep.c: Blow away all tdesc stuff.
210 Provide functions for all the frame-related macros in
211 tm-delta88.h. Adopt i960-style EXTRA_FRAME_INFO.
212 (examine_prologue, frame_find_saved_regs, skip_prologue): borrow
213 from i960-tdep.c and adapt to the function prologues on the 88k.
214 (read_next_frame_reg): Borrow from mips-tdep.c.
215 FIXME: frame_locals_address should go away.
216
217 * tm-delta88.h: Dump all the tdesc stuff.
218 Macros for all frame-related stuff call fns of same name.
219 Remove duplicated definitions. FP_REGNUM becomes same as
220 SP_REGNUM.
221
222 * xm-88k.h: Eliminate lots of library dependencies, now handled
223 in libiberty. Eliminate KDB nonsupport.
224
225 * doc/gdbint.texinfo: Add rudiments on frames. FIXME, add more.
226
227
228 * stack.c (frame_info): Mark frameless functions.
229 Print locals address (FIXME, remove if same).
230 * blockframe.c: Comment changes, FIXME after.
231 * coffread.c: Even without TDESC, need to zap "@" symbols.
232 Don't register for wierd format names; change the names in BFD.

245
246 Allow setting breakpoints on C++ destructors.
247 * valops.c (destructor_name_p): Don't check TYPE_HAS_DESTRUCTOR,

249 * symtab.c (decode_line_1): For example (see above), here.
250 * buildsym.c, symtab.h: Remove TYPE_FLAGS_HAS{CON,DE}STRUCTOR
251 flags since they are no longer used.

253 Fixes to support C++ methods with functional parameters.
254 * c-exp.y (func_mod rule): Allow (and ignore) list of parameter
255 types in a function type.
256 * eval.c (parse_and_eval_type), value.h: New function,
257 parse_and_eval_type, is based on old code from check_stub_method.
258 But don't actually evaluate the cast, since that calls
259 value_cast(), whcih may fail. Just extract the type
260 from the parsed expression.
261 * values.c (check_stub_method): While looping through the
262 arguments, adjust depth *after* parameter has been handled.
263 Replace call and setup of parse_and_eval with new function
264 parse_and_eval_type.

274 sun386-xdep.c, symm-xdep.c, umax-xdep.c, values.c, xcoffread.c:
275 Change all instances of use of fixed args concat() to variable
276 args concat() now located in libiberty.
277

285 xm-rs6000.h, rs6k-opcode.def, rs6k-opcode.h: New files.
286 * xcoffexec.c: New file for handling AIX shared libraries.
287
288 Mon Nov 11 19:14:31 1991 Fred Fish (fnf at cygnus.com)
289
290 * core.c: Minor rewording of message to user containing name of
291 (and possibly arguments to) the program that generated a core
292 file.
293
294 * elfread.c: Remove the register_addr() stub now that it is no
295 longer needed.
296
297 * procfs.c: Move misplaced #endif for ATTACH_DETACH. Add new
298 fetch_core_registers() function for core file support.
299
300 Sat Nov 9 13:37:57 1991 Fred Fish (fnf at cygnus.com)
301
302 * dwarfread.c (dwarf_psymtab_to_symtab): Remove leftover call

304
305 * elfread.c: Re-enable compilation of register_addr() stub
306 whenever it is not supplied by coredep.c
307

388
389 Fri Nov 8 23:38:48 1991 John Gilmore (gnu at cygnus.com)

397
398 Thu Nov 7 18:26:15 1991 Steve Chamberlain (sac at rtl.cygnus.com)
399
400 * Makefile.in: link with libiberty after libreadline, since
401 readline might want something in libiberty.
402 * m88k-xdep.c: Fixed the register offsets in the ptrace_user
403 struct for BCS 88k machines.
404 * xm-m88k.h: don't define USIZE if already defined.
405 * configure.in: Added delta88 target.
406
407 Thu Nov 7 04:51:19 1991 John Gilmore (gnu at cygnus.com)
408
409 * am29k-pinsn.c, am29k-opcode.h: Fix decoding of mtacc, dmac, fmac.
410
411 * tm-*.h: Remove READ_DBX_FORMAT, COFF_FORMAT, and
412 READ_MIPS_FORMAT, which have been unused since BFD. Still
413 remaining is COFF_NO_LONG_FILE_NAMES.
414 * tm-sun3.h, tm-altos.h: Remove detritus accidentally left from
415 function calling code moved to m68k-tdep.c.
416
417 Wed Nov 6 17:21:59 1991 John Gilmore (gnu at cygnus.com)
418
419 * coffread.c: Eliminate c_nsyms in favor of c_naux.
420 Complain if no auxents on .bf and .ef FCN symbols, and assume
421 lots of line numbers.
422 (init_linenos, enter_linenos): Use a sentinel at the end of the
423 read-in linenos, to make for a fast, safe loop-end test.
424
425 Wed Nov 6 02:54:08 1991 Steve Chamberlain (sac at cygnus.com)
426
427 * coffread.c (read_coff_symtab): coffread used to rely on the
428 x_sym.x_misc.x_lnsz.x_lnno field giving the # of linnos in a
429 function. Two of the formats I'm using (29k and 88k) don't seem to
430 set it. Ths patch to fcn_last_line and (enter_linenos) is an
431 attempt to use the actual size of the linno table in the file to set
432 the number of linenos to process.
433
434 Tue Nov 5 22:47:46 1991 Steve Chamberlain (sac at cygnus.com)

436 * Makefile.in: put a - infront of the mv y.tab.c c-exp.tab.c and
437 mv y.tab.c m2-exp.tab.c, so that if bison is used, and the files
438 are created in place, so the mv fails, then the make continues.
439
440 Tue Nov 5 16:47:47 1991 Per Bothner (bothner at cygnus.com)
441
442 Add C++ as a separate language.
443 * defs.h (enum language): Add language_cplus.
444 * dwarfread.c (end_symtab): Support language_cplus.
445 * c-exp.y: Add new struct language_defn cplus_language_defn.
446 Don't set c to be the default language (see main.c).
447 * c-exp.y (yylex): Only look for field of this if
448 language is C++. (First difference from C!)
449 * language.c: Add case branches for C++ (currently, all
450 the same as C). Also, add c++ to "usage" note for "set lang".
451 * valprint.c (typedef_print). Add case branches for C++.
452 * main.c (main): New way to set initial language: Look at
453 file extension of psymtab containing main(). (Same as we
454 do for symtabs, but avoid loading the symtab yet.)
455 * symtab.c: New routine find_main_psymtab(), used by main()
456 to set initial language.
457 * symfile.c (allocate_symtab): Move code for mapping file
458 extensions-> languages to new deduce_language_from_filename().
459
460 Fix a C++ problem when looking for methods in super-classes.
461 There was confusion between base and derived types.
462 * valops.c (value_fn_field): Change function interface.
463 * values.c: Use new value_fn_field interface.
464
465 Mon Nov 4 10:49:33 1991 Per Bothner (bothner at cygnus.com)
466
467 * infrun.c: Fixed typo in comment.
468 * utils.c: All the v*fprintf emulation is now in libiberty,
469 so we can get rid of some junk.
470 * xm-sun3os4.h, xm-sun4os4.h, xconfig/decstation, xconfig/i386sco,
471 xconfig/sun3os4, xconfig/sun4os4: Don`t need HAVE_STRSTR any more.
472 * m68k-pinsn.c (print_insn_arg): Support BB/BW/BL
473 type operands, as used by branch instructions.
474 * gmalloc.c: Fix prototype of memcpy.
475 * elfread.c: Comment out register_addr, since it conflicts
476 with the one in coredep.c.
477 * buildsym.h: Remove extern declarations of two functions
478 that are really static in buildsym.c.
479 * tm-mips.h: Add symbolic names for more registers.
480 * mips-xdep.c (store_inferior_registers): Use new register names.
481 * xm-mips.h: Simplify REGISTER_U_ADDR, since it is now
482 only used for core files, not ptrace. Therefore,
483 the KERNEL_U_ADDR hack is no longer needed.
484 The mapping to ptrace number is now in in mips-xdep.c.
485 * mips-xdep.c: Define REGISTER_PTRACE_ADDR (using the
486 mapping from the old REGISTER_U_ADDR), and use it
487 in {fetch,store}_inferior_registers.
488 * mipsread.c: Rename #include ecoff.h to new name coff-mips.h.
489 * mips-tdep.c (mips_push_dummy_frame, mips_pop_frame):
490 Save/restore FP regs correctly (?).
491 * dbxread.c: Remove duplicate define_symbol and type_synonym_name
492 (these had been previously moved to buildsym.c).
493 Hence, define_symbol becomes extern instead of static.
494 * buildsym.c (read_struct_type): Comment out bogus handling
495 of C++ operator methods. Minor hacking of reading of class
496 contexts. Make define_symbol non-static, so dbxread.c can call it.
497
498 Fri Nov 1 11:05:47 1991 John Gilmore (gnu at cygnus.com)
499
500 * mipsread.c (read_mips_symtab, read_the_mips_symtab): Use real
501 filename with error messages.
502 * stack.c (frame_select_command): Rename to select_frame_command
503 to avoid "fr" and "fra" having nonunique completions.
504 * symfile.c (sort_symtab_syms): Ignore sort of zero symtab *.
505 (symfile_init): Print file format name when unable to handle it.
506 (free_named_symtabs): Use BLOCKVECTOR rather than obsolete BLOCKLIST.
507 * symmisc.c (free_symtab): Only free linetable if nonzero.
508 * symtab.h: Remove obsolete BLOCKLIST macros.
509
510 Thu Oct 31 18:12:43 1991 Stu Grossman (grossman at cygnus.com)
511
512 * infrun.c (wait_for_inferior): another stepi/nexti fix. Ensure
513 that stop_step is 1 at bottom of main loop. I don't know why this
514 needs to be done, but it helps me sleep better at night.
515
516 Sun Oct 27 18:18:39 1991 Stu Grossman (grossman at cygnus.com)
517
518 * main.c (initialize_history): Read history after reading all
519 init files.
520
521 Sun Oct 27 14:09:25 1991 John Gilmore (gnu at cygnus.com)
522
523 * buildsym.c: Break out initial malloc sizes.
524 (record_line): Record directly in a subfile. Alloc on demand.
525 (compare_line_numbers): Add from xcoffread.c.
526 (end_symtab): New params say whether to sort pendings and
527 linetable. Patch block stabs if defined. Shrink linetable before
528 allocating the symtab.
529 * buildsym.h: Delete line_vector* and prev_line_number. Add
530 global_stabs and file_stabs for xcoffread.
531 * dbxread.c (start_subfile): Move to buildsym. Change above calls.
532 * symtab.h: LINETABLE(symtab) can now be null. Zap LINELIST.
533 * symmisc.c, symtab.c: Cope with null LINETABLEs.
534
535 * blockframe.c: Pass fromleaf to INIT_EXTRA_FRAME_INFO.
536 * tm-29k.h, tm-88k.h, tm-i960.h, tm-irix3.h, tm-mips.h, tm-pyr.h,
537 tm-sparc.h: Accept fromleaf parameter.
538 * c-exp.y (yyerror): Pass error message if given.
539 * configure.in: Add rs6000 host and target.
540 * inflow.c (new_tty): O_NOCTTY kludge for RS/6000.
541 * symfile.h (entry_point): Add.
542
543 Sat Oct 26 00:16:32 1991 John Gilmore (gnu at cygus.com)
544
545 * buildsym.c: New file. Breaks out symbol-table-building routines
546 from dbxread.c, so they can be shared with xcoffread.c.
547 * buildsym.h: New file. Declarations for buildsym.c users.
548 * dbxread.c: Remove large chunks into buildsym.c.
549 * Makefile.in: Add buildsym.c and buildsym.h.
550
551 * symfile.c (syms_from_bfd): New routine.
552 (add_symbol_file): Call it to do the real work.
553 (syms_from_bfd): Initialize entry_point before calling symfile_init.
554 * symtab.h, symfile.c, coffread.c, mipsread.c, dwarfread.c:
555 Avoid declaring or setting entry_point (symfile.h & symfile.c cope).
556
557 Fri Oct 25 10:58:16 1991 Mark Eichin (eichin at cygnus.com)
558
559 * cplus-dem.c (cplus-demangle): added support for templates, static
560 data, and the new (correct) mangling for destructors.
561
562 * dwarfread.c: (dwarfwarn): created a varargs version of
563 dwarfwarn, for non __STDC__ compilers.
564
565 * c-exp.y: (yylex): added match for "template" token.
566 (typebase): added TEMPLATE name '<' type '>' clause, for explicit
567 specification of template types.
568
569 * symtab.c: (lookup_template_type): new function for finding
570 templates in symbol table.
571 (type_name_no_tag): changed to explicitly check for s/u/e at the
572 beginning of the symbol - if it is a template, none of these will
573 be there (but the name will still contain spaces.)
574
575 Fri Oct 25 18:59:32 1991 Per Bothner (bothner at cygnus.com)
576
577 Various fixes to improve g++ debugging.
578 * symtab.h: Add is_const and is_volatile flags for each method.
579 These are bit fields - take their space from voffset,
580 which shrinks to 30 bits. Since voffset is now a bitfield,
581 make it unsigned for portability. This changes its interpretation
582 slightly: Static methods now have voffset 1 instead of -1,
583 and virtual offsets start at 2, not 1.
584 * symtab.c: Renamed gdb_mangle_typename to gdb_mangle_name,
585 since it now returns an entire magled method name, not just
586 the type part. This avoids some duplication.
587 It also allows us to correctly mangle const and volatile
588 methods (using the new is_const and is_volatile bit fields
589 mentioned above).
590 * valprint.c (type_print_base), values.c (check_stub_method):
591 Simplify by using new gdb_mangle_name.
592 * values.c (value_headof): Fix to correctly handle single
593 inheritance (actually two fixes, either of which suffices).
594 * dbxread.c (read_struct_type): Handle const and volatile
595 method specifiers.
596 * dbxread.c (read_struct_type): Yet one more place where
597 we must handle '\\' continuations.
598 * valprint.c (vtbl_ptr_name): Add final '\0'.
599
600 Fri Oct 25 16:06:38 1991 Stu Grossman (grossman at cygnus.com)
601
602 * tm-sparc.h, tm-68k.h (EXTRACT_RETURN_VALUE): fix output of
603 short return values for sparc and 68k. Patch from Paul Eggert.
604
605 * coffread.c, coredep.c, i386-xdep.c: install patches for
606 SysV/386 3.2 from Mauro DePalma.
607
608 Fri Oct 25 02:02:13 1991 John Gilmore (gnu at cygnus.com)
609
610 * core.c (core_file_info), exec.c (exec_file_info): Print file
611 type. Use printf_filtered.
612
613 * valops.c (value_fetch_lazy): Avoid 0-length fetches.
614
615 Thu Oct 24 23:06:40 1991 Fred Fish (fnf at cygnus.com)
616
617 * dwarfread.c: Add casts to remove compiler warnings.
618
619 * tm-3b1.h, tm-68k.h, tm-altos.h, tm-amix.h, tm-hp300bsd.h,
620 tm-hp300hpux.h, tm-isi.h, tm-news.h, tm-pn.h, tm-sun2.h,
621 tm-sun3.h: Remove locally duplicated code for calling functions
622 in the inferior. The only differences were in the specific trap
623 vectors used and whether or not an fpu was present. These are
624 now handled by appropriate definitions of BPT_VECTOR and
625 HAVE_68881 respectively. Other minor obvious cleanups.
626
627 * valops.c: Correct a minor misspelling.
628
629 * utils.c: Remove local BSD/USG hacks that are now in libiberty.
630
631 * dwarfread.c: Remove prototype for dwarfwarn. Does not work
632 with <varargs.h>.
633
634 Thu Oct 24 09:33:44 1991 John Gilmore (gnu at cygnus.com)
635
636 * stack.c (frame_command): Always print. Use new
637 frame_select_command to select a frame without printing.
638
639 * dwarfread.c: Use <varargs.h>, since <stdarg.h> is not portable.
640
641 Thu Oct 24 01:32:51 1991 Fred Fish (fnf at cygnus.com)
642
643 * dwarfread.c: New file for DWARF debugging format support.
644
645 * elfread.c: New file for ELF object file format support.
646
647 * procfs.c: New file for SVR4 /proc (process file system) support.
648
649 * tm-amix.h, xm-amix.h, tconfig/amix, xconfig/amix: New files for
650 Amiga UNIX support.
651
652 * xm-svr4.h, tm-svr4.h: New files for SVR4 support.
653
654 * xm-m68k.h: New file for host machines with m68k cpu.
655
656 * Makefile.in: Add elfread.c and dwarfread.c to SFILES_MAINDIR.
657 Add elfread.o and dwarfread.o to OBS.
658
659 * symfile.h: Add "elf" to list of supported formats in comment.
660
661 * c-exp.y, defs.h, symtab.h, valprint.c: Add three new builtin
662 types to gdb, builtin_type_long_double, builtin_type_complex, and
663 builtin_type_double_complex. Add and use new TARGET_SHORT_BIT,
664 TARGET_INT_BIT, TARGET_LONG_BIT, TARGET_FLOAT_BIT,
665 TARGET_DOUBLE_BIT, TARGET_LONG_DOUBLE_BIT, TARGET_COMPLEX_BIT, and
666 TARGET_DOUBLE_COMPLEX_BIT, as the sizes in bits of the indicated
667 types on the target machine (ala the existing TARGET_LONG_LONG_BIT).
668
669 * infrun.c: When using SVR4 /proc interface instead of ptrace(),
670 call proc_set_exec_trap() to setup child to stop at first instruction.
671
672 * inftarg.c: When using SVR4 /proc interface, call proc_wait()
673 rather than wait().
674
675 * m68k-tdep.c: Add new routines supply_gregset(), fill_gregset(),
676 supply_fpregset(), and fill_fpregset(), which are machine
677 dependent support routines for SVR4 /proc interface.
678
679 * utils.c: Add warning_setup() and warning(). Warning() behaves
680 the same as error() except that it returns normally rather than
681 jumping back to command level. Modules that don't want to call
682 warning() for some reason, but want to produce their own warnings,
683 can call warning_setup() to ensure compatibility with the way
684 warning() and error() deal with the terminal.
685
686 * symtab.c: Make internal errors produce more useful messages.
687
688 * tm-68k.h: Move code that is duplicated in almost every single
689 m68k based machine's configuration files to this common file.
690 Duplications in the configuration files still need to be removed
691 (FIXME).
692
693 * infrun.c (child_create_inferior): System V versions must call
694 setpgrp() with no arguments, to comply with prototyping typically
695 in <unistd.h>.
696
697 * munch: Add support for SVR4 style nm output.
698
699 * dbxread.c, mipsread.c symmisc.c, symtab.c: Remove the object
700 file specific fields from the partial symbol table structure and
701 replace them with a pointer to private data for each different
702 flavor of object file reader to initialize appropriately.
703
704 Wed Oct 23 09:38:20 1991 John Gilmore (gnu at cygnus.com)
705
706 * xconfig/sun[34]os4: Add note about strstr botch on sunos4.0.3c
707 and previous.
708
709 * mipsread.c (fixup_undef_type): New function. If a struct /
710 union / enum is defined in a header file but nowhere else used,
711 (by typedefing, pointer referencing or declaration) the mipsread code
712 builds the complete tree for the structure but leaves its code as
713 TYPE_CODE_UNDEF as it doesn't know what kind of aggregate it is.
714 Guess its type based on the details of the members.
715
716 Tue Oct 22 18:04:32 1991 Stu Grossman (grossman at cygnus.com)
717
718 * infrun.c (wait_for_inferior): Check return value from
719 find_pc_line.
720
721 Mon Oct 21 17:47:03 1991 Stu Grossman (grossman at cygnus.com)
722
723 * infrun.c (wait_for_inferior): fix stepi/nexti that was broken
724 by my last edit to this routine.
725
726 Mon Oct 21 14:27:43 1991 John Gilmore (gnu at cygnus.com)
727
728 * tm-sun3.h (FIX_CALL_DUMMY): problem with cross debugging.
729 FIX_CALL_DUMMY does unaligned accesses and/or forgets to byte swap
730 the values before putting them into the dummy code. (From Peter
731 Schauer)
732
733 Mon Oct 21 10:04:39 1991 Steve Chamberlain (steve at rtl.cygnus.com)
734
735 * configure.in: added ebmon target.
736
737 Wed Oct 16 22:49:58 1991 John Gilmore (gnu at cygnus.com)
738
739 GDB-4.2 release!
740
741 * Makefile.in: Roll VERSION to 4.2.
742 * README, TODO, WHATS.NEW: Update.
743
744 * core.c (core_open): Improve error message for bad file.
745 Pass .reg virtual memory address to fetch_core_registers to help
746 it find the registers in the core-file header.
747 * coredep.c (fetch_core_registers): Take new argument, use it,
748 and pass it to register_addr to locate the block of registers.
749 * xm-mips.h: Update KERNEL_U_ADDR for new scheme. Cleanup a bit.
750
751 * dbxread.c (read_dbx_symtab, process_one_symbol): Handle
752 Sequent N_FN_SEQ like everybody else's N_FN.
753
754 * main.c: Circumvent SCO cc bug with #if !!defined(USG).
755 * tm-i386v.h: #endif guck.
756 * xconfig/i386*: Remove -Dgetpagesize()=4096 kludge.
757 * xconfig/i386sco: Add HAVE_STRSTR to avoid ANSI bdeath.
758 * xconfig/tahoe: Add REGEX, which seems to be missing.
759
760 * coredep.c: Add <sys/types.h> for SCOnix.
761 * dbxread.c (read_dbx_symntab): Avoid coredump on malformed file.
762 * printcmd.c (print_formatted): Flush output before disassembly.
763
764 Tue Oct 15 20:12:32 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
765
766 * doc/refcard.tex (sec "Working Files"): consistent metavars and
767 other improvements, due to comments by François Pinard
768 (pinard@iro.umontreal.ca)
769
770 * doc/gdb.texinfo (appendix "Installing GDB"): changes in
771 configure, and improvenets related to Pinard's refcard comments
772
773 Tue Oct 15 08:45:12 1991 John Gilmore (gnu at cygnus.com)
774
775 Changes from Fred Fish:
776 * tm-68k.h (FPI_REGNUM): Add.
777 * infrun.c (child_create_inferior): flush stdout and stderr
778 before forking.
779 * configure.in: Handle amigados, amix hosts and targets.
780 * inflow.c: Handle TIOCGLTC_BROKEN for Amiga.
781
782 From Andreas Schwab:
783 * values.c (show_convenience): Use printf_filtered.
784 * main.c (define_command): Check result of lookup_command for
785 exact match.
786 (echo_command): Use printf_filtered, and force output out.
787
788 * dbxread.c (read_enum_type): Avoid Modula-2 kludge that breaks C
789 programs.
790 * i387-tdep.c (double_to_i387): Fix typo for double_to_ieee_extended.
791 * utils.c (_initialize_utils): If !ISATTY, don't paginate.
792 * configure.in, tconfig/decstation, xconfig/decstation: Rename
793 dec3100 to decstation.
794
795 Mon Oct 14 13:37:50 1991 Roland H. Pesch (pesch at cygnus.com)
796
797 * doc/gdb.texinfo: Catch up to changes recorded here in ChangeLog
798 (nodes Continuing and Stepping; Memory; Targets) clarifications
799 due to Larry Breed
800
801 Fri Oct 11 23:27:06 1991 John Gilmore (gnu at cygnus.com)
802
803 * tm-{irix3,mips,nindy960,pn,symmetry,vx960}.h: Move
804 REGISTER_U_ADDR to corresponding xm- file. Sugg. by Peter Schauer.
805
806 * symmisc.c (print_partial_symtabs): Add printpsyms debug cmd.
807
808 * m68k-tdep.c (m68k_push_dummy_frame, m68k_pop_frame): Add
809 generic routines for calling inferior functions.
810
811 * blockframe.c (inside_main_scope, inside_entry_scope): New.
812
813 * copying.awk: Filter formfeeds out of copying & warrantee.
814 Make them available as `show copying' and `show warrantee' also.
815 * main.c (print_gnu_advertisement): Advt `show' commands.
816
817 Thu Oct 10 17:25:47 1991 John Gilmore (gnu at cygnus.com)
818
819 * mach386-xdep.c: Even when cross-compiling, leave in the
820 core-file reading code.
821 * core.c (get_core_registers): Avoid coredump if no .reg section.
822
823 Wed Oct 9 17:03:34 1991 John Gilmore (gnu at cygnus.com)
824
825 * mipsread.c, coffread.c: initialise TYPE_VPTR_FIELDNO to -1.
826 This avoids coredumps under `set print object on' in value_headof
827 (called erroneously by value_from_vtable_info) for `p &struct'
828 or `p *struct'. From Peter Schauer.
829
830 Mon Oct 7 00:06:52 1991 John Gilmore (gnu at cygnus.com)
831
832 * Makefile.in: Roll version to 4.1.2.
833 * dbxread.c: Use aout64.h, not a.out.gnu.h. Get external symbol entry
834 size from BFD (but, FIXME, we don't yet read external nlists's and
835 convert them to internal nlists's before handling them -- we still
836 assume they have the same size and alignment.) Use SET_NAMESTRING
837 everywhere useful.
838 * exec.c (exec_file_command): Move dead coff-encapsulation code
839 to BFD.
840 * m88k-tdep.c, m88k-xdep.c: Remove encap test and #inc <a.out.h>.
841
842 Fri Oct 4 22:30:06 1991 John Gilmore (gnu at cygnus.com)
843
844 * configure.in, tm-i386v.h, xm-i386v.h: Intel 386 Mach host port.
845 * xm-i386mach.h, mach386-xdep.c, xconfig/i386mach: New files.
846
847 Fri Oct 4 17:04:31 1991 Per Bothner (bothner at cygnus.com)
848
849 More patches from Peter Schauer <pes@regent.e-technik.tu-muenchen.de>:
850 * mips-xdep.c (store_inferior_registers): Don't try to
851 write the (pseudo) FP.
852 * mipsread.c (parse_partial_symbols): Improved algorithm for
853 setting pst->texthigh.
854
855 Fri Oct 4 16:47:32 1991 Roland H. Pesch (pesch at cygnus.com)
856
857 * doc/Makefile: make TEXINPUTS include . everywhere
858
859 Fri Oct 4 00:35:56 1991 John Gilmore (gnu at cygnus.com)
860
861 * coffread.c, dbxread.c, symfile.c, symmisc.c, symtab.h: Remove
862 vestiges of typevectors, which were for symsegs and are no longer
863 used. (From a question by Eliot Dresselhaus

866 Thu Oct 3 09:33:26 1991 John Gilmore (gnu at cygnus.com)
867
868 * dbxread.c, coffread.c: static-ize functions that were
869 gratuitiously external. (From Fred Fish.)
870
871 * c-exp.y: sym->class to SYMBOL_CLASS (sym).
872
873 * dbxread.c (dbx_lookup_type): Keep doubling size of typevector
874 until it is large enough.
875
876 * dbxread.c (read_type): Handle error case slightly better.
877 Make complaint message not C++-specific.
878
879 Wed Oct 2 17:21:07 1991 Stu Grossman (grossman at cygnus.com)
880
881 * infrun.c (wait_for_inferior): Fix step/next so that you only
882 stop at the beginning of a new line. This fixes various problems
883 with for loops, nested if-else's and switch statements.
884
885 Tue Oct 1 06:33:55 1991 John Gilmore (gnu at cygnus.com)
886
887 * symtab.c (lookup_symtab_1, lookup_symbol): "fatal" errors
888 between symtabs and psymtabs become ordinary error()s.
889
890 * dbxread.c (read_dbx_symtab): Relocate end_of_text_addr
891 properly, making "end pc" correct in shared lib psymtabs.
892 (From Guy Harris <guy@auspex.com>.)
893
894 Mon Sep 30 13:15:31 1991 John Gilmore (gnu at cygnus.com)
895
896 * dbxread.c: Enable, but soften, const_vol_complaint.
897 (read_dbx_symtab): N_STSYM and N_LCSYM define static vars.
898 Ditto Gould N_NBSTS and N_NBLCS. Also, all types in the psymtab
899 should be file-scope, not global.
900 (read_struct_type): Remove ancient multiple-inheritance warning.
901 (read_range_type): Check base type, complain & patch if undefined.
902 * stack.c (frame_info): Demangle the function name in `info stack'.
903 (From Peter Schauer)
904
905 Sat Sep 28 10:02:33 1991 John Gilmore (gnu at cygnus.com)
906
907 * eval.c (evaluate_subexp_for_address): Don't use
908 TYPE_POINTER_TYPE directly (it might be zero if this type has
909 never had a pointer created before); use lookup_pointer_type.
910 * symtab.c (lookup_method_type): Arguments were swapped in all
911 callers, so fix it here. I'm amazed this worked at all!
912
913 Fri Sep 27 18:09:31 1991 John Gilmore (gnu at cygnus.com)
914
915 * c-exp.y, m2-exp.y: Define more yysymbols that happen to be
916 "bss" rather than "data" symbols, but which still conflict.
917 * m2-exp.y: Lint.
918
919 * coffread.c (coff_symfile_read): Use xmalloc, not malloc.
920 * core.c (core_files_info): Shorten output.
921 * exec.c (exec_files_info): Ditto.
922 (build_section_table): Ignore zero-length sections.
923 * language.c, printcmd.c: Lint.
924 * language.h (get_frame_language): Declare.
925 * saber.suppress: update.
926 * stack.c (find_relative_frame): Remove complex code that was
927 #if 0'd, stick with simple code. Lint.
928 * saber.suppress: Update a bit.
929 * symfile.c (add_symbol_file_command): Add "?" to question.
930 * utils.c (parse_escape): Avoid \a due to bdead compilers.
931 * value.h: Declare typedef_print.
932
933 * valprint.c (val_print, type_print_base): TYPE_CODE_RANGE less
934 kludgey.
935
936 * nindy-tdep.c (nindy_frame_chain_valid): Use lookup_misc_func.
937 (Reported by Mark Peek <mark@imagen.com>.)
938
939 * solib.c (solib_map_sections): Relocate all sections, even
940 though only the text section's size is tracked. Mark ld_text
941 for eventual elimination as we generalize to N sections.
942
943 * infrun.c (wait_for_inferior): Don't check if the PC is in a
944 call_dummy if we were stopped by a random signal that is being
945 passed to the program. This produced wierd results when calling
946 functions in the inferior and signals (e.g. SIGALRM) were in use.
947
948 Tue Sep 24 18:05:30 1991 John Gilmore (gnu at cygnus.com)
949
950 * infrun.c (IN_SIGTRAMP): Not parenthesized properly.
951 Bugfix from Paul Eggert <eggert@twinsun.com>.
952 * tm-ultra3.h (IN_SIGTRAMP): Ditto.
953 * valprint.c (print_floating): Print 9 digits for IEEE floats.
954 From Paul Eggert.
955
956 Mon Sep 23 15:50:07 1991 John Gilmore (gnu at cygnus.com)
957
958 * Makefile.in: Roll VERSION to 4.1.1.
959 * source.c (line_info): Peter Schauer fixes a bug I introduced in
960 hex conversion.
961
962 Fri Sep 20 16:10:52 1991 John Gilmore (gnu at cygnus.com)
963
964 GDB-4.1 release!
965
966 * Makefile.in (VERSION): Set to 4.1.
967 * language.c (set_language_command): Print useful help message,
968 and restore the language string after giving help.
969 * valprint.c (typedef_print): Print typedef in C or M2.
970 * symtab.c (list_symbols): Use it.
971 * main.c (main): Avoid any output before (gdb) prompt when -q.
972 * language.c (set_language_command): Handle errors by restoring
973 the language string to its current state (fix from A. Beers).
974 * doc/gdbint.texinfo: Roll in information from README. Rearrange
975 "how to install" and "how to print the doc" stuff so it drops
976 easier into README.
977 * configure.in: Rename rtpc CPU to romp to match config.sub.
978 * README, WHATS.NEW, TODO: Update for gdb-4.1.
979
980 Fri Sep 20 17:39:14 1991 Roland H. Pesch (pesch at cygnus.com)
981
982 * doc/gdb.texinfo: Updates from ChangeLog. set/show write,
983 autoloading shared libs, copyright etc on GDB startup, clean up $_
984 and $__ index refs, set/show listsize and related updates to list
985 cmd. New host/target configs.
986
987 Fri Sep 20 15:46:00 1991 Roland H. Pesch (pesch at cygnus.com)
988
989 * doc/Makefile: generate aux version-no file doc/gdbVN.m4
990 from main Makefile.in version definition
991 doc/gdb.texinfo: use version recorded in doc/gdbVN.m4 for current
992 GDB version no refs
993 Makefile.in (setup-to-dist): generate doc/gdbVN.m4
994
995 * doc/gdb.texinfo: merge new language-switching and lang-specific
996 doc by Andrew Beers
997
998 Fri Sep 20 15:00:57 1991 Per Bothner (bothner at cygnus.com)
999
1000 * mcheck.c: Add __ONEFILE kludge to allow compilation by non-ANSI
1001 compilers (which may lack stddef.h).
1002
1003 Fri Sep 20 13:29:42 1991 John Gilmore (gnu at cygnus.com)
1004
1005 * dbxread.c (read_dbx_symtab, process_one_symbol): N_FN and
1006 N_WARNING are the same except for the N_EXT bit, so just use their
1007 values alone, rather than OR-ing them with N_EXT.
1008
1009 Fri Sep 20 12:27:55 1991 Stu Grossman (grossman at cygnus.com)
1010
1011 * mipsread.c (parse_lines): Deal with negative extended line
1012 offsets correctly.
1013
1014 * c-exp.y, m2-exp.y: #define yyerrflag and yynerrs to avoid
1015 global symbol conflicts.
1016
1017 Fri Sep 20 02:28:15 1991 John Gilmore (gnu at cygnus.com)
1018
1019 * .gdbinit: Move 'set complaints' to top, so it runs even in
1020 case we aren't debugging GDB.
1021 * language.c (_initialize_language): Fix type check and range
1022 check documentation strings.
1023 * utils.c (!HAVE_VPRINTF): Define vfprintf as a function, so
1024 language.c can use it. (Though language.c should really not be
1025 handling warnings/errors the way it does, FIXME.)
1026 * symtab.c (lookup_primitive_type): const lint.
1027
1028 Bugfix from Peter Schauer:
1029 * source.c (lines_to_list): Make signed, to avoid comparison
1030 going unsigned and complaining that -3 is too high for 21 lines.
1031 * stack.c (lines_to_list): Ditto.
1032
1033 Thu Sep 19 23:33:41 1991 John Gilmore (gnu at cygnus.com)
1034
1035 * Makefile.in (HFILES): Add minimon.h.
1036 (VERSION): Roll version number to 4.0.95.
1037 (gdb.tar.Z, make-proto-gdb.dir, setup-to-dist, gdb-XXX.tar.Z):
1038 New rules for building distributions. Normal distribution
1039 is built by doing `make -f Makefile.in gdb.tar.Z' in the directory
1040 one level up from here; it calls make-proto-gdb.dir to build a
1041 directory `proto-gdb' which is an image of the release. The old
1042 `gdb.tar.Z' rule still works too.
1043 * config.sub, configure: Roll in latest from ..
1044
1045 Thu Sep 19 17:41:24 1991 Roland H. Pesch (pesch at cygnus.com)
1046
1047 * doc/gdbint.texinfo: Reorder contents; reorganize new-host,
1048 new-target, and new-config chapters; fix minor typos; come closer
1049 to usual GNU markup conventions for @file @samp @code @var.
1050
1051 Thu Sep 19 17:04:12 1991 Per Bothner (bothner at cygnus.com)
1052
1053 Patches from Peter Schauer <pes@regent.e-technik.tu-muenchen.de>:
1054 * mipsread.c (parse_partial_symbols): Enter the name of all
1055 structs/unions... into the psymtab so we can access them if the
1056 symtab is not read in.
1057 * mips-tdep.c: Remove some unneeded #includes.
1058 * xconfig/dec3100: Add HAVE_STRSTR.
1059
1060 Thu Sep 19 15:14:23 1991 John Gilmore (gnu at cygnus.com)
1061
1062 * Makefile.in: Circumvent Sun Make bug on *-exp.tab.o.
1063 * c-exp.y, m2-exp.y: Lint.
1064 * m2-exp.y: Avoid using yytname[] which is a Bison-ism.
1065 * valprint.c (val_print_fields): Check for stub type.
1066 * mipsread.c (_initialize_mipsread): Avoid using
1067 builtin_type_void at initialize time.
1068 (mipscoff_symfile_read): use it now.
1069
1070 Wed Sep 18 15:55:51 1991 John Gilmore (gnu at cygnus.com)
1071
1072 Merge multiple-language support, and partial Modula-2 support,
1073 from Andrew Beers <beers@cs.buffalo.edu>.
1074
1075 * i387-tdep.c: New file, consolidates most 80387 support,
1076 and eliminates host dependency on double<->extended conversions.
1077 * i386-xdep.c, symm-xdep.c: Remove most 387 support.
1078 * xconfig/i386{sco,v,v-g,v32,v32-g}: Now need i387-tdep.o.
1079

1168
1169 Tue Sep 17 08:37:41 1991 John Gilmore (gnu at cygint.cygnus.com)
1170
1171 Add Andrew Beers' changes for Modula-2 support. His ChangeLog
1172 entries are enclosed herein. Not all of these changes
1173 have been merged into the master GDB sources -- check the
1174 ChangeLog above here for the merge log.
1175
1176 Mon Jun 3 17:05:45 EDT 1991
1177
1178 m2-exp.y Created. Tested outside of GDB for a few days. Proper
1179 operators were added, C specific operators and tokens
1180 removed. yylex() revamped to some extent. Still things
1181 missing from the grammar, such as sets.
1182 Tested for two weeks in GDB v3.5.
1183
1184 Tue Jun 11 17:23:48 EDT 1991
1185
1186 m2-exp.y Added boolean constants TRUE and FALSE to the grammar
1187 so they are built-in. Sort of a hack.
1188
1189 Fri Jun 14 12:53:51 EDT 1991
1190
1191 m2-exp.y Added range checking for numeric constants. Any numeric
1192 constant is assumed to be of builtin type INTEGER unless:
1193 (1) it is octal or hexadecimal, in which case it is a
1194 CARDINAL; (2) it is too big to fit into an INTEGER, in
1195 which case it is a CARDINAL.
1196 eval.c Added simple range checking for +, -, and * on integers.
1197 Doesn't work very well for *, since 6 * 1,000,000,000 =
1198 1,705,032,704, which fails the simple test of result >=
1199 first_operand, no matter in what order the operands are.
1200
1201 Tue Jun 18 14:11:30 EDT 1991
1202
1203 Broke the parser into parts, one containing the C grammar and the other
1204 containing code to be shared by all of the grammars.
1205
1206 The following files no longer exist:
1207
1208 expread.y
1209 expread.tab.c
1210
1211 The following files were added:
1212
1213 c-exp.y (The C grammar)
1214 m2-exp.y (The Modula-2 grammar)
1215 parser-code.c (Code that is shared by the above grammar)
1216 parser-code.h
1217 parser-defs.h
1218
1219 Makefile.dist Changed to reflect the above dependencies. NOTE: It is
1220 now necessary to use the Bison compiler compiler, since it
1221 will generate function/variable prefixes other than yy.
1222
1223 Tue Jun 18 16:47:49 EDT 1991
1224
1225 symtab.[ch] Added the external variable working_lang, than holds the
1226 value of the current working language.
1227 Added the ennumerated type language_mode, with the values
1228 language_auto and language_manual, the former meaning that
1229 GDB sets working_lang as needed, and the latter meaning
1230 that the value of working_lang is totally under user
1231 control.
1232 symtab.[ch] Added the Modula-2 pervasive types INTEGER, CARDINAL,
1233 REAL, BOOLEAN and CHAR. Also added the type codes
1234 TYPE_CODE_BOOL and TYPE_CODE_CHAR.
1235 utils.c Added set_language_command and show_language_command to
1236 implement the GDB support commands "set language" and
1237 "show language".
1238 expression.h A number of identifiers were added to the type exp_opcode
1239 to facilitate Modula-2 builtin functions, integer
1240 division, and array indexing.
1241
1242 Wed Jun 19 13:25:58 EDT 1991
1243
1244 language.h Added the macro STRICT_TYPE, which evaluates to non-zero
1245 if the language specified by working_lang requires the use
1246 of strict typing of expressions. Eventually, even this
1247 will be able to be changed by the user.
1248 Added the macro RANGE_CHECK, which evaluates to non-zero
1249 if the language specified by working_lang requires the
1250 checking of a value against the domain of its type.
1251 Eventually, even this will be able to be changed by the
1252 user.
1253 language.[ch] Predicates involving types (simple_type, ordered_type,
1254 same_type, integral_type, numeric_type, character_type,
1255 boolean_type, float_type) are added. These predicates are
1256 based on the current value of working_lang, and are handy
1257 in type-checking.
1258
1259 Wed Jun 19 15:39:34 EDT 1991
1260
1261 eval.c Added the function type_array_rank which computes the rank
1262 of an array type.
1263 valarith.c Added the funtion value_bool, which when given a integer
1264 value.h value (ie. struct value *) as an argument, it returns a
1265 boolean value (ie. struct value *) true if that integer
1266 is non-zero, and a boolean value false otherwise.
1267 valprint.c Added cases for TYPE_CODE_BOOL, so Modula-2 BOOLEAN values
1268 will print out properly.
1269
1270 Wed Jun 19 16:36:34 EDT 1991
1271
1272 valops.c Added the function value_capitalize, which returns it
1273 value.h argument capitalized if its argument is a lowercase
1274 letter, or the argument unchanged if its argument is not a
1275 letter.
1276 valarith.c Added the function range_check_p, which returns non-zero
1277 value.h if its value argument is between the integral bounds upper
1278 and lower.
1279 Added the function range_check_enum_p, which makes sure
1280 that its value argument is a valid member of the domain of
1281 its type argument.
1282 Added the function range_check_range_p, which makes sure
1283 its value argument lies between the upper and lower bounds
1284 of its type argument, which must be a ranged type.
1285 Added the function check_array_index, which range and type
1286 checks an index of an array.
1287 Added the function value_multi_subscript, which computes
1288 array[idx1,idx2...idxN], given a value array and an array
1289 of values representing indicies.
1290 values.c Changed value_from_long to work with TYPE_CODE_CHAR and
1291 unpack_long to work with TYPE_CODE_BOOL and
1292 TYPE_CODE_CHAR.
1293
1294 Wed Jun 19 18:04:08 EDT 1991
1295
1296 symtab.c Stored pervasive types in a structure and make
1297 lookup_pervasive_type() a lookup function that was based
1298 on working_lang. If lookup_pervasive_type() returned
1299 non-zero, then that value was returned (a fix, since
1300 before it simply wouldn't return the pervasive type.)
1301 language.h Added the macro CAST_IS_CONVERSION, which evaluates to
1302 non-zero if the language specified by working_lang means
1303 "conversion" when it says "cast".
1304 valops.c Added the function value_real_cast(), which performs a
1305 value.h *cast*, not a *conversion*, which is what value_cast()
1306 does when it can. In particular,
1307 value_cast(<float_type>,4) = 4.0, while
1308 value_real_cast(<float_type>,4) = some mess.
1309 eval.c Modula-2 builtin functions implemented: ABS, CAP, CHR,
1310 parser-code.c FLOAT, HIGH, MAX, MIN, ODD, ORD, TRUNC, and VAL.
1311 expression.h Added macros MAX_OF_TYPE and MIN_OF_TYPE to work with MAX
1312 and MIN on integral types. *NOTE*: These are currently
1313 hardcoded to work only if there are 8 bits per storage
1314 unit. FIXME.
1315 eval.c Made logical functions call value_bool to return a
1316 properly typed boolean value, based on working_lang.
1317
1318 Thu Jun 20 11:55:27 EDT 1991
1319
1320 valprint.c Types now print out in a Modula-2 fashion. This works for
1321 the cases when the type is printed out step-by-step, that
1322 is, it doesn't work when the name of a structured type
1323 (which includes the keyword "struct", etc.) is simply
1324 displayed.
1325 FIXME: Perhaps this is bad. Parts of it seem to kludgey,
1326 since type specifications in C and Modula-2 are very
1327 different. The C printing of a type is very recursive,
1328 whereas in Modula-2 it is generally very simple. C has
1329 type prefixes and suffixes, which have no real analogue in
1330 Modula-2. Maybe type_print() should call a language
1331 specific type printer. This is also advantageous if we
1332 compile GDB to exclude some of the languages. We'll just
1333 leave those functions out.
1334
1335 Thu Jun 20 16:57:10 EDT 1991
1336
1337 dbxread.c When reading the complete symbol table in (via
1338 psymtab_to_symtab()), the number and types of function
1339 arguments are added to a function type. define_symbol()
1340 calls add_param_to_type() to accomplish this.
1341 Assumption: when we come across a function definition
1342 (N_FUN symbol with an 'f' or 'F' in the name), its
1343 arguments will appear before another function definition.
1344 When a function is found, a pointer to its type is placed
1345 in the global in_function_type. Changes that
1346 add_param_to_type() makes are to this global.
1347 valprint.c The type of a function now includes (for Modula-2) the
1348 types of its parameters.
1349 eval.c Type checking and a check for the proper number of
1350 arguments is now done for function calls. Not sure of the
1351 impact this has on C++ member function yet.
1352
1353 Thu Jun 20 19:58:48 EDT 1991
1354
1355 valprint.c Rewrote the type printer. Broke it into two language
1356 specific parts, adding the functions type_print_m2() and
1357 type_print_m2_1().
1358 An unfortunate consequence is this: if you debugging a C
1359 program in Modula-2 mode (why?), info types does not work
1360 well with regular expressions, since the types are printed
1361 out in Modula-2 terminology, but stored in C terminology.
1362 language.[ch] Added the functions new_type_last(), type_keyword(), and
1363 type_sep() to aid in the printing of typedefs.
1364 symtab.c Made the printing of typedefs as language independent as
1365 possible through calls to new_type_last(), type_keyword(),
1366 and type_sep().
1367
1368 Fri Jun 21 11:50:26 EDT 1991
1369
1370 dbxread.c Check all incoming ennumerated types. If it looks like
1371 Modula-2's BOOLEAN type, then change the type_code of the
1372 type to TYPE_CODE_BOOL so we can process it as a boolean
1373 variable.
1374 valprint.c Replaced some of the 0x%x with calls to sprintf and
1375 hexformat() in val_print().
1376 language.[ch] Added the function hex_to_string(), which converts its
1377 integral argument to a hexadecimal number (format is
1378 language based) and returns the result as a string.
1379
1380 Mon Jun 24 12:25:07 EDT 1991
1381
1382 valprint.c Some functions call type_print_1() directly, instead of
1383 value.h using type_print(), so they can specify where (column) to
1384 print things. Since type_print() takes care of language
1385 dependence, that needs to be called first. Added a
1386 parameter depth to type_print() (so it is now like
1387 type_print_1). Changed type_print to type_print_at, and
1388 made type_print a macro that passes a depth argument of
1389 zero.
1390 symmisc.c Changed all calls to type_print_1 to calls to
1391 type_print_at.
1392 Makefile.dist Made it possible to build GDB for a specific set of
1393 depend languages. Do this by passing a definition for the macro
1394 LANGS to make. LANGS should be a string containing a
1395 space-separated list of language names (ie. LANGS="c m2").
1396 The default is to build all languages. Note that grammar
1397 files must follow the naming convention of <lang>-exp.y.
1398 gdb.lang This holds the current value of the LANGS macro. It is
1399 examined every time make is called, and is updated if
1400 necessary.
1401 eval.c Added #ifdef _LANG_<lang> to these files.
1402 expread.c Still need to add them to dbxread.c and coffread.c.
1403 main.c
1404 source.c
1405 symtab.c
1406 utils.c
1407 valarith.c
1408 valprint.c
1409
1410 Mon Jun 24 16:33:11 EDT 1991
1411
1412 language.[ch] Added the functions hexformat_pre() and
1413 hex_to_string_pre(), which take a prefix argument to
1414 include in the format string. Thus, hexformat_pre("08") will
1415 return "0x08x" (if the working language is language_c).
1416 Made hexformat() and hex_to_string() calls to the above
1417 with "" as the prefix argument.
1418
1419 am29k-pinsn.c, arm-pinsn.c, breakpoint.c, convex-tdep.c, exec.c, core.c,
1420 dbxread.c, i386-pinsn.c, i386-stub.c, i386-xdep.c, i960-pinsn.c,
1421 infcmd.c, inflow.c, m68k-pinsn.c, m68k-stub.c, m88k-pinsn.c,
1422 mips-pinsn.c, mips-tdep.c, ns32k-pinsn.c, printcmd.c, pyr-pinsn.c,
1423 pyr-tdep.c, pyr-xdep.c, remote-vx.c, remote.c, solib.c, source.c,
1424 stack.c, sun386-xdep.c, symfile.c, symm-xdep.c, symmisc.c, tahoe-pinsn.c,
1425 valprint.c, vax-pinsn.c
1426
1427 Changed all occurences of 0x%[0-9]*l*x in printf format strings to
1428 calls to hexformat() and hex_to_string(). Format strings without
1429 the leading "0x" were ignored.
1430
1431 depend Updated to take the above into account.
1432
1433
1434 Tue Jun 25 15:27:18 EDT 1991
1435
1436 symtab.h Added the types range_mode_t, range_check_t, type_mode_t,
1437 and type_check_t to keep track of the current state of
1438 range and type checking.
1439 main.c Added the variables range_mode, range_check, type_mode,
1440 and type_check to record the current state of range and
1441 type checking. Added initialization code to main().
1442 language.h Changed the macros STRICT_TYPE and RANGE_CHECK to examine
1443 the above variables.
1444
1445
1446 Tue Jun 25 17:57:08 EDT 1991
1447
1448 dbxread.c process_one_symbol() updates the variable (enum language)
1449 source_lang based on the extension of the filename
1450 contained in the N_SO sybmol that started this symtab.
1451 When end_symtab() is called, the value of source_lang is
1452 put into the language field.
1453 stack.c select_frame() sets working_lang (and possibly type_check
1454 and range_check) to the language field of the symtab
1455 associated with the frame that is selected if working_mode
1456 is language_auto. If working_mode is language_manual, a
1457 warning is printed and working_lang is not set.
1458 language.c Added the function set_type_range(), which sets the value of
1459 type_check and range_check (if their modes call for
1460 automatic setting) based on the current value of
1461 working_lang. A non-zero argument will cause the current
1462 settings to be output.
1463
1464
1465 Wed Jun 26 14:51:40 EDT 1991
1466
1467 eval.c Added range checks on assignment.
1468 m2-exp.y Added the grammar for sets to the language. Currently,
1469 these do not do anything except print an error message.
1470
1471 Wed Jun 26 17:01:04 EDT 1991
1472
1473 m2-exp.y Added the ability for parse_number() to parse negative
1474 numbers. A global flag is set upon encountering a unary
1475 minus. This was done to make, for example, 1 parse as a
1476 CARDINAL, and not as an integer, per Wirth's examples in
1477 Programming in Modula-2 ed.4.
1478 valprint.c Added support for "set radix 2" by then setting
1479 output_format to 't'.
1480 eval.c Implemented range checking on subrange types. Added calls
1481 to range_check_range_p for BINOP_ASSIGN and BINOP_VAL.
1482 Implemented MIN and MAX for ennumerated types. The
1483 minimum value of an ennumerated type is defined by Wirth
1484 as the first identifier, and the maximum as the last.
1485 m2-exp.y Made octal numbers ending with "B" be characters and those
1486 ending with "C" be numbers, per Wirth's book. (p. 34)
1487
1488 Thu Jun 27 14:11:52 EDT 1991
1489
1490 stack.c select_frame() now only sets working_lang, it does not
1491 notify the user. If working_mode is language_manual, then
1492 a warning is issued once.
1493 main.c At the end of each call to execute_command(), working_lang
1494 is checked against the local static (enum language)
1495 current. If they differ and working_mode is
1496 language_auto, the new settings of language, type and
1497 range checking are printed out.
1498 stack.c Modified frame_info() to include the language of the
1499 current frame in the output of "info frame".
1500 language.[ch] Added the function language_str() which returns the name
1501 of the current language.
1502
1503 Fri Jun 28 15:33:14 EDT 1991
1504
1505 m2-exp.y Added the built-in procedures INC, INCL, DEC, and DECL to
1506 the language. INCL and DECL currently cause an error,
1507 since sets are not implemented yet. INC and DEC are
1508 implemented as PREINCREMENT/PREDECREMENT with one
1509 argument, and as ASSIGN_MODIFY with two arguments.
1510 eval.c Added type checking to the above cases.
1511 value.h Added not_lval_constant to the lval_type ennumerated type.
1512 not_lval_constant means that the value is a constant
1513 value; that is 3 or 'a' or TRUE, not as in a constant
1514 identifier. This is used to help coerce numbers such as 3
1515 to either signed or unsigned numbers.
1516 valops.c Added the function value_coerce_constants() which coerces
1517 constant integers as following: if one is a constant and
1518 the other is not, the constant's type is set to the type
1519 of the other argument. If both are constants and one is
1520 signed, the other is converted to a signed constant.
1521
1522 Sat Jun 29 17:26:29 EDT 1991
1523
1524 valarith.c Added a better range checker. It now checks range
1525 (successfully) on integral operations [+-] (signed and
1526 unsigned) for any C sized type. Still does not work well
1527 for multiplication.)
1528 int_in_size() returns an integer that is coerced to fit into
1529 specified number of bytes.
1530
1531 Mon Jul 1 13:04:14 EDT 1991
1532
1533 language.[ch] Added the function binop_result_type(), which returns the
1534 builtin (struct type *) type that would be the result of a
1535 binop on the two values V1 and V2.
1536
1537 Wed Jul 3 19:22:53 EDT 1991
1538
1539 source.c Extended source_info() to include the source language in
1540 the output from "info source".
1541
1542 Fri Jul 5 13:48:52 EDT 1991
1543
1544 utils.c Moved the support functions for the GDB set/show commands
1545 dealing with language into language.c.
1546 language.c Added the function language_info(), which displays info
1547 about the current working language, type and range check
1548 settings. Called via the GDB command "info language".
1549 Added an initialization routine _initialize_language(),
1550 that sets defaults for the language, type and range
1551 variables and sets up the new GDB commands.
1552 main.c Language setup moved to language.c.
1553 depend Rebuilt.
1554
1555 Mon Jul 8 10:10:22 EDT 1991
1556
1557 valarith.c Debugged the range checker for arithmetic. Still does not
1558 work for multiplication very well.
1559
1560 Mon Jul 8 12:40:37 EDT 1991
1561
1562 language.[ch] Added the function value_true() which returns non-zero if
1563 its argument represents a boolean true value.
1564 breakpoint.c Changed breakpoint_cond_eval() to call value_true() to
1565 check the truth of an expression.
1566
1567 Thu Jul 11 12:51:34 EDT 1991
1568
1569 language.[ch] Added the predicate structured_type(), which returns
1570 non-zero if the argument is a structured type.
1571 Added the predicate pointer_type(), which returns non-zero
1572 if the argument is a pointer type.
1573 eval.c Added the ability to do addition and substraction on
1574 pointers and integers. This case simply bypasses the
1575 type checker.
1576
1577 Thu Jul 11 14:41:42 EDT 1991
1578
1579 include/stab.def
1580 Added the symbol N_DEFD (0x4a) which is a definition
1581 module dependency that is used by the GNU Modula-2
1582 compiler and the linker. It is not important to GDB,
1583 except that [dbx|coff|mips]read.c should ignore these
1584 symbols.
1585
1586 Fri Jul 12 16:07:00 EDT 1991
1587
1588 valprint.c Changed the TYPE_LENGTH(type) >= 0 to TYPE_LENGTH(type) >
1589 0 in val_print(). Also added statements to the else part
1590 to coerce type (argument to val_print) to a pointer type
1591 if it is an "array of unspecified length".
1592 valops.c Added the function value_m2_string(), which returns a
1593 (value) value which is a constant string, whose type is
1594 (ARRAY [0..n] OF CHAR). The length field of the type
1595 structure is set to zero, so it will be interpreted as an
1596 "array of unspecified length".
1597 stack.c Moved the language/frame mismatch check to
1598 main.c:execute_command().
1599 main.c The working language is recorded each time
1600 execute_command() is executed. If working lang has
1601 changed during its execution, then the new
1602 language/type/range info is printed out for the user. If
1603 the working language does not match the language of the
1604 frame, a warning is issued.
1605
1606 Sat Jul 13 16:16:39 EDT 1991
1607
1608 eval.c Moved all the type-checking stuff for operators to
1609 language.[ch] language.c. This is so we can keep language-specific
1610 stuff (like for what type operators are defined) in
1611 language.c.
1612 language.[ch] Added the function binop_type_check(), which checks to see
1613 if its two (value) arguments are type-compatible with its
1614 opcode argument. The opcode should represent an operation
1615 involving an operator. Also added the macro function
1616 unop_type_check, which calls binop_type_check with a
1617 NULL second argument.
1618 expprint.c Added Modula-2 operators to the op_print_tab, so info
1619 expression.h break works correctly. Also added "op_string", which
1620 returns the string corresponding to the (enum exp_opcode)
1621 opcode that is its argument.
1622
1623
1624 Sat Jul 13 18:26:18 EDT 1991
1625
1626 coffread.c Added code to record the type of function arguments with
1627 each paricular function. Code is very similar to that
1628 added to dbxread.c.
1629 dbxread.c Moved add_param_to_type() to symtab.c
1630 symtab.[ch] Added function add_param_to_type() from dbxread.c
1631
1632 *** NOTE: The above additions have not been tested.
1633
1634 Mon Jul 15 12:50:47 EDT 1991
1635
1636 langauge.[ch] Added the functions type_error and range_error, which work
1637 like error() except if the type/range mode is set to
1638 *_mode_warn, then they do not do a return_to_top_level(),
1639 but merely print a warning.
1640 Also changed [set|show]_[type|range]_command() to support
1641 the new "warn" feature.
1642
1643 Thu Jul 18 17:50:54 EDT 1991
1644
1645 mipsread.c Added code to record the type of function arguments with
1646 each particular function. Code is very similar to that
1647 added to dbxread.c.
1648
1649 *** NOTE: The above additions have not been tested.
1650
1651 Fri Jul 19 11:19:10 EDT 1991
1652
1653 defs.h Added macros MAX_OF_SIZE, MIN_OF_SIZE, UMAX_OF_SIZE, and
1654 UMIN_OF_SIZE, which when given a size of a numeric type,
1655 return the maximum and minimum value it can hold. UMAX...
1656 and UMIN... return the result for unsigned types.
1657 symtab.h Added the macros MAX_OF_TYPE and MIN_OF_TYPE to operate on
1658 struct types. They call above macros.
1659 dbxread.c Renamed the MAX and MIN_OF_TYPE macros to ..._OF_CTYPE to
1660 avoid a name conlict with the above.
1661 c-exp.y Added range checking on numeric constants in
1662 parse_number() for completeness.
1663 valarith.c Made binop_user_defined_p() and unop_user_defined_p()
1664 return 0 if working_lang is not language_c.
1665
1666 Thu Aug 8 14:17:22 EDT 1991
1667
1668 main.c
1669 printcmd.c
1670 breakpoint.c Documentation strings of some commands changed to
1671 eliminate the references to the C language where
1672 appropriate.
1673
1674 Tue Aug 13 15:48:03 EDT 1991
1675
1676 m2-exp.y Added qualified identifiers to the grammar. The semantics
1677 are slightly different from those of the GDB operator ::
1678 c-exp.y
1679 m2-exp.y Added a rule to each grammar of the form: start ::= exp |
1680 type_exp, where type_exp is any valid type expression.
1681 expression.h
1682 eval.c Added the opcode OP_TYPE, and an error case in eval.c.
1683 printcmd.c Modified ptype_command() so it actually parses the input
1684 (necessary for type expressions with scope qualifiers).
1685 Added the function ptype_eval() which expects an
1686 expression composed of one OP_TYPE element.
1687 *.[ch] Replaced all occurences of parse_c_expression with
1688 parse_expression
1689 *.[ch] Replaced all occurences of parse_c_1 with parse_exp_1

1706 * remote-vx.c: Move <stdio.h> to top, for FILE. Fix from
1707 John S <basrai%kanga.dnet@c3po.sm-alc.af.mil>.
1708
1709 * utils.c (wrap_here): Avoid wrap action of fputs_filtered if
1710 chars_per_line is at maximum (user typed `set width 0'). Fix
1711 from Andreas Schwab <schwab@ls5.informatik.uni-dortmund.de>.
1712
1713 Tue Sep 17 17:31:04 1991 Stu Grossman (grossman at cygnus.com)
1714
1715 * coredep.c: include ptrace.h where necessary.
1716 * mipsread.c(parse_lines): fix unsigned char problem that was
1717 messing up line numbers on SGI's and possibly other MIPS based
1718 platforms.
1719 * infrun.c (child_create_inferior): use better test to check
1720 return val from setpgrp().
1721 * tm-irix3.h, xm-irix3.h, tconfig/irix3, xconfig/irix3: add these
1722 for sgi/irix support.
1723
1724 Wed Sep 18 04:33:31 1991 Per Bothner (bothner at cygnus.com)
1725

1730
1731 Patch together `text_start' and `text_end' for 29K port.
1732
1733 * exec.c (exec_command): If NEED_TEXT_START_END, define the
1734 variables and set them based on the exec file.

1736 * valops.c (call_function_by_hand): declare text_end.
1737
1738 * inferior.h: Eliminate CANNOT_EXECUTE_STACK in favor of
1739 defining CALL_DUMMY_LOCATION as BEFORE_TEXT_END. This is
1740 because machines that do this will also have to know to
1741 set NEED_TEXT_START_END. Besides, it was a redundant way to
1742 say the same thing.
1743 * tm-29k.h, tm-convex.h, tm-np1.h: Eliminate
1744 CANNOT_EXECUTE_STACK, define CALL_DUMMY_LOCATION and
1745 NEED_TEXT_START_END.

1753 * am29k-pinsn.c (print_insn): Handle NOP specially. Avoid %#x
1754 format string; use 0x%x instead.
1755 * am29k-tdep.c: Use DUMMY_SAVE_GREGS and RETURN_REGNUM.
1756 * ultra-xdep.c, xm-ultra.h: New files for Ultracomputer host system.
1757 * xm-rtbsd.h: New host support for RT/PC running BSD Unix.
1758 * inflow.c: Handle `short' process group IDs.
1759 * infptrace.c (fetch_register): Support CANNOT_FETCH_REGISTER,
1760 and check for ptrace errors.
1761 * coffread.c (SDB_REG_TO_REGNUM): Define if not already.
1762 (coff_symfile_init): Initialize text_bfd_scnum.
1763 (read_coff_symtab): Use it to find the text [and absolute?] sections.
1764 * ../config.sub: Add vendor nyu and os "sym[1-9]*".
1765 * configure.in: Add hosts rtpc-*-* and a29k-*-*.
1766 Merge target arm case with other "easy" cases. Add target
1767 cases a29k-*-none (rehack of am29k), a29k-*-kern (remote to
1768 Ultracomputer kernel), and a29k-*-sym1 (ultracomputer OS's user
1769 process).
1770 * minimon.h, remote-adapt.c, remote-mm.c: Add.
1771 * munch: Cope with RT/PC putting fns in data segment.
1772 Restore ability to override `nm' by specifying MUNCH_NM.
1773 * xconfig/rtbsd, xconfig/ultra3: New host systems.
1774 * tconfig/a29k: Rename from tconfig/am29k. Add remote-mm
1775 and remote-adapt. Remove encapsulated coff #define's (the
1776 support should go in BFD, and gdb shouldn't know or care).
1777 * tconfig/a29k-kern: Same, but for remote kernel debugging.
1778 * tconfig/ultra3: For debugging user processes on Ultra3/Sym1.
1779 * tm-29k.h: Update BADMAG (though it should go away).
1780 Allow the register definitions to be overridden in another
1781 tm-file. Fix SR_REGNUM. Add a mess of _REGNUM's. Separate
1782 RETURN_REGNUM from GR96_REGNUM and DUMMY_SAVE_GREGS from
1783 DUMMY_SAVE_GR96, for handling kernel calling conventions
1784 that use GR64+ rather than GR96+.
1785 * tm-ultra3.h: New file, for use on Ultra3 Unix as well as for
1786 remote debugging of Ultra3 kernel. Includes tm-29k.h and
1787 overrides various things.
1788
1789 * remote-mm.c (mm_attach, mm_wait): Handle attach like
1790 child_attach does, making a clean stop in the newly attached
1791 program.
1792 * remote-eb.c: Lint.
1793
1794 * coffread.c: Make coffread independent of any particular
1795 variant of COFF. Avoid #include-ing any particular one except
1796 internalcoff.h. BFD now passes key values for symbol reading
1797 as part of its coff_data structure (LINESZ, SYMESZ, AUXESZ,
1798 and the symbol masks and shifts); use them.
1799 Remove obsolete end_of_text_addr.
1800
1801 * exec.c: Remove unused include files.
1802
1803 Wed Sep 11 19:38:44 1991 John Gilmore (gnu at cygint.cygnus.com)
1804
1805 * Makefile.in (documentation targets): Pass $(M4).
1806 Bugfix from eggert@twinsun.com (Paul Eggert).
1807
1808 * stack.c (down_silently_command): Check for stack existence.
1809
1810 Tue Sep 10 23:08:29 1991 John Gilmore (gnu at cygint.cygnus.com)
1811
1812 * Makefile.in (VERSION): Update to 4.0.3.
1813
1814 Tue Sep 10 09:19:29 1991 John Gilmore (gnu at cygint.cygnus.com)
1815
1816 * core.c (core_file_command): Print frame at coredump with
1817 its level number, by calling print_stack_frame.
1818 * frame.h: Add selected_frame_level, print_stack_frame.
1819 * frame.h, stack.c: Remove print_sel_frame, print_selected_frame.
1820 * convex-tdep.c, convex-xdep.c, infcmd.c, inflow.c, infrun.c:
1821 Change print_sel_frame and print_selected_frame callers to
1822 print_stack_frame.
1823
1824 * dbxread.c (read_ofile_symtab): Avoid empty else clause.
1825 * symfile.c (free_named_symtabs): Ditto.
1826 * main.c (main): wrap_here needs an arg.
1827 * solib.c (find_solib): Avoid memory access if _DYNAMIC is zero.
1828 (solib_add): Avoid noise.
1829 (solib_create_inferior_hook): Lint.
1830 (sharedlibrary_command): Move dont_repeat to here.
1831 * utils.c (error): Call wrap_here to force buffered output.
1832
1833 Small patches from Peter Schauer:
1834
1835 * coffread.c (start_symtab): Free any existing line_vector before
1836 malloc-ing new one.
1837 (read_coff_symtab): Ditto for type_vector.
1838
1839 * source.c (lines_to_list): New variable, replacing function.
1840 (all uses): Use as variable.
1841 (_initialize_source): Add 'set listsize' and 'show listsize'.
1842 * utils.c (lines_to_list): Remove function.
1843 * stack.c (print_frame_info): Use as variable.
1844 * defs.h (lines_to_list): Remove declaration.
1845
1846 Mon Sep 9 13:45:57 1991 John Gilmore (gnu at cygint.cygnus.com)
1847
1848 * breakpoint.c (insert_breakpoints): Restore warning about
1849 the program might be running in another process, but only for
1850 systems with this brain death (#ifdef ONE_PROCESS_WRITETEXT).
1851 * xm-hp300bsd.h, xm-mips.h, xm-vax.h: Define it.
1852
1853 * utils.c (error): if error_pre_print is set, print the string
1854 first.
1855 * main.c (main, print_gnu_advertisement, print_gdb_version):
1856 Reformat legalese so it always prints, but acts as an "I'm here"
1857 message while symbols are being read. If any errors occur,
1858 print a few newlines to set off the message and start it at the
1859 left margin. Remove mention of "help" command, and don't yak
1860 about symbol reading.
1861 (catch_errors): Error string is now printed first in case of
1862 error, not last.
1863 * command.c (undef_cmd_error, lookup_cmd): On undefined command,
1864 suggest the "help" command.
1865
1866 * Makefile.in (VERSION): Set to 4.0.2.
1867
1868 Thu Sep 5 23:49:48 1991 John Gilmore (gnu at cygint.cygnus.com)
1869
1870 * .gdbinit: Remove useless "rr" command. Set complaints
1871 to 1 for people debugging gdb.
1872
1873 * breakpoint.c, remote-vx.c: Reword strings printed by
1874 catch_errors callers.
1875
1876 Wed Sep 4 11:07:50 1991 John Gilmore (gnu at cygint.cygnus.com)
1877
1878 * WHATS.NEW: "history write -> history save". Doc "write on/off".
1879 (Fix from kenc@viewlogic.com.)
1880
1881 Fix some infrastructure to be able to cope with host and target
1882 machines with different sized basic types (ints, ptrs, etc).
1883 (Idea from pierre@la.tce.com (Pierre Willard).)
1884
1885 * values.c (value_from_longest): Rename from value_from_long.
1886 Handle pointer types as well as integers, so that targets with
1887 different pointer sizes from the host can be accomodated.
1888 * breakpoint.c, convex-tdep.c, eval.c, expprint.c, printcmd.c,
1889 valarith.c, valops.c, valprint.c, value.h, values.c: Rename
1890 uses of value_from_long to value_from_longest.
1891 * eval.c, findvar.c, printcmd.c, valarith.c, valops.c: Pass
1892 the correct pointer type to value_from_long{est}.
1893
1894 * doc/gdb.texinfo ($_, $__): Describe types of these variables.
1895
1896 * remote-vx.c: Remove obsolete code for calling functions via
1897 vxworks kludge interface (it referenced value_from_long).
1898
1899 * valops.c (value_string): Find malloc with lookup_misc_func, not
1900 raw search.
1901
1902 Tue Sep 3 18:37:46 1991 John Gilmore (gnu at cygint.cygnus.com)
1903
1904 Make writing to files work properly. (Fixes to BFD are also needed.)
1905
1906 * core.c (core_open): Open file ourselves, read or r/w, depending on
1907 write_files. Use bfd_fdopenr.
1908 * gdbcore.h (write_files): New variable.
1909 * exec.c (write_files): Define variable, add set&show for it.
1910 (exec_file_command): Use write_files to open for read or r/write.
1911
1912 Make shared library reading happen automatically. These changes
1913 are mostly from Peter Schauer <pes@regent.e-technik.tu-muenchen.de>.
1914
1915 * inferior.h (stop_soon_quietly): Add to exported variables.
1916 * infrun.c (child_create_inferior): call solib hook, if defined.
1917 (child_attach): call solib hook, if defined.
1918 * solib.c: Include inferior.h. Add from_tty to so_list as kludge.
1919 (find_solib): Use lookup_misc_func rather than hand-rolled.
1920 (symbol_add_stub): New stub for catch_errors.
1921 (solib_add): Avoid output if !from_tty. Catch errors rather
1922 than just calling symbol_file_add and bombing.
1923 (solib_create_inferior_hook): Interface with the target process
1924 to let it read and alloc shared libs, then figure out what it did.
1925
1926 * core.c (validate_files): Fix typo, soften warning.
1927 (Fix from Hiroto Kagotani <kagotani@cs.titech.ac.jp>.)
1928
1929 * utils.c (fputs_demangled): Avoid duplicate printing if
1930 demangling is off. (Fix from J.T. Conklin <jtc@cayenne.com>.)
1931
1932 * infrun.c (proceed): Cast -1 to (CORE_ADDR) before comparing.
1933 (Fix from pierre@la.tce.com (Pierre Willard).)
1934
1935 * main.c (catch_errors): Change argument to a char * from an int,
1936 since a char * can point to a struct full of glop, but an int
1937 is not guaranteed to be able to hold a pointer.
1938 * breakpoint.c (breakpoint_cond_eval, bpstat_stop_status,
1939 breakpoint_re_set_one, breakpoint_re_set): Adapt.
1940 * core.c (core_open, solib_add_stub): Adapt.
1941 * remote-vx.c (symbol_stub, add_symbol_stub, callers): Adapt.
1942
1943 Wed Aug 28 18:18:05 1991 John Gilmore (gnu at cygint.cygnus.com)
1944
1945 * Makefile.in: Update VERSION to 4.0.1. Evade GNU Make bug
1946 by adding .NOEXPORT target.
1947
1948 Fri Aug 23 17:14:25 1991 John Gilmore (gnu at cygint.cygnus.com)
1949
1950 * GDB-4.0 release!
1951 * Update README.
1952 * Makefile.in (VERSION): Roll to 4.0.
1953 (gdb.tar.Z): Make refcard.ps as well, for shipment.
1954
1955 Fri Aug 23 14:07:09 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1956
1957 * doc/gdb.texinfo: minor rewordings, crossref to ptype from print,
1958 more on printsyms.
1959
1960 * doc/Makefile, Makefile.in: generate "gdb-all.texi" rather than
1961 "gdb-all.texinfo"
1962
1963 * doc/rdl-apps.texi: renamed from rdl-apps.texinfo
1964
1965 * Makefile.in, doc/Makefile, doc/.Sanitize, doc/gdb.texinfo:
1966 reflect above name change
1967
1968 * WHATS.NEW: correct pointer to refcard.
1969
1970 * doc/gdb.texinfo: update New Features, Installing
1971
1972 * doc/gdbint.texinfo: add short description of configure +template
1973
1974 Fri Aug 23 11:46:08 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1975
1976 * doc/gdb.texinfo: update, fix bugs in "Installing" appendix
1977
1978 Fri Aug 23 01:02:00 1991 John Gilmore (gnu at cygint.cygnus.com)
1979
1980 * Makefile.in: Add config.sub, make doc/rdl-apps.texinfo for
1981 tar file, add dependencies for referenced doc files.
1982
1983 Thu Aug 22 22:17:06 1991 Stu Grossman (grossman at cygint.cygnus.com)
1984
1985 * coffread.c, symfile.c, stack.c: saberized.
1986
1987 Thu Aug 22 16:20:27 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1988
1989 * doc/refcard.tex: permuted Essential Commands sec
1990
1991 * doc/gdb.texinfo: new C++ chapter; revised installation appendix;
1992 new doc for
1993 set/show symbol-reloading
1994 default set complaints 0
1995 info all-registers
1996 RET-repeat disabled after prompted long displays
1997 processID (attach) interpretation of 2nd GDB cmdline arg
1998
1999 Thu Aug 22 14:05:47 1991 Stu Grossman (grossman at cygint.cygnus.com)
2000
2001 * expread.y, coffread.c, dbxread.c, target.c, mem-break.c,
2002 cplus-dem.c, values.c, valprint.c, symfile.c, remote.c,
2003 breakpoint.c, main.c: lint.
2004
2005 Thu Aug 22 02:02:26 1991 John Gilmore (gnu at cygint.cygnus.com)
2006
2007 Install new configuration scheme for GDB and friends.
2008
2009 * config.sub: Translate ordinary names to three-part names.
2010 * configure: Use three-part names internally.
2011 * configure.in: Translate three-part names to filenames.
2012
2013 * README, WHATS.NEW: Update for gdb-4.0.
2014 * Makefile.in: Roll VERSION to 3.99.
2015
2016 Wed Aug 21 18:21:09 1991 John Gilmore (gnu at cygint.cygnus.com)
2017
2018 * infptrace.c (KERNEL_U_ADDR_BSD): Include a.out.gnu.h.
2019 * i960-tdep.c, m68k-tdep.c, sparc-tdep.c, tm-i960.h,
2020 tm-m68k.h, remote-nindy.c: Change ext_format_XXX structs
2021 to single structures rather than arrays; when passing
2022 their address, use &. This avoids trouble with bdead compilers.
2023 * mcheck.c: Don't include <stdlib.h>; just declare "void abort();"
2024 instead. This avoids portability headaches.
2025 * mips-tdep.c (mips_do_registers_info): Only print FP regs if
2026 asked to.
2027 * source.c (open_source_file): Avoid ANSI const bdeath by
2028 skipping declaration and then casting result value.
2029 * tm-hp300bsd.h: Clarify comment.
2030 * utils.c (strstr): Result is const char *; ANSI bdeath.
2031 * xm-hp300bsd.h: Define HOST_BYTE_ORDER. Redefine INT_MIN,
2032 since system include file defines it differently from "defs.h",
2033 though the two are equivalent for our purposes.
2034 * tconfig/hp300bsd: Add m68k-tdep.o.
2035
2036 Tue Aug 20 16:01:11 1991 John Gilmore (gnu at cygint.cygnus.com)
2037
2038 * tconfig/sun*4: Remove warnings about system assembler.
2039
2040 Mon Aug 19 13:44:46 1991 John Gilmore (gnu at cygint.cygnus.com)
2041
2042 * mcheck.c: Avoid warning about undeclared abort fn.
2043 * tm-sparc.h (PC_ADJUST): Avoid calling error() from this;
2044 it causes recursive calls to error() when used in cleanups.
2045 To do so requires that we make it a function, so we do.
2046 * sparc-tdep.c (sparc_pc_adjust): New implem of PC_ADJUST.
2047 * utils.c (do_cleanups): Remove the current cleanup from the
2048 chain *before* calling it, in case error() is called from it.
2049 The result won't be pretty, but won't be an infinite loop either.
2050
2051 Mon Aug 19 00:41:04 1991 Michael Tiemann (tiemann at cygint.cygnus.com)
2052
2053 * dbxread.c (read_struct_type): Grok anon structs for C++.
2054 (vb_name, vptr_name): Null terminate these strings.
2055
2056 Fri Aug 16 08:31:03 1991 John Gilmore (gnu at cygint.cygnus.com)
2057
2058 Minor bug fixes from BSD Net2 gdb:
2059
2060 * blockframe.c (get_prev_frame_info): If FRAME_CHAIN_COMBINE
2061 returns 0, there is no previous frame.
2062 * breakpoint.c (commands_command): If !from_tty, don't call
2063 input_from_terminal_p().
2064 * dbxread.c (record_misc_function): Speed up slightly.
2065 (compare_psymbols): Ditto.
2066 * infcmd.c (do_registers_info): Take a second argument to
2067 determine whether to print float registers. "info registers"
2068 does not do so anymore. "info all-registers" does, now.
2069 * mips-tdep.c, pyr-tdep.c (xxx_do_registers_info): Take second
2070 arg and ignore it.
2071 * tm-mips.h, tm-pyr.h (DO_REGISTERS_INFO): Pass second arg.
2072 * inflow.c (initialize_inflow): Set tflags_ours correctly.
2073
2074 Other fixes:
2075
2076 * breakpoint.c (bpstat_do_actions): Use a cleanup to restore
2077 executing_breakpoint_commands if we are interrupted by error.
2078 * coffread.c (init_lineno): Avoid problem with zero-sized linetab
2079 versus malloc/free. From: john@labtam.labtam.oz.au (John Carey).
2080 * core.c (solib_add_stub, core_open): Call SOLIB_ADD inside a
2081 catch_errors() so we can setup the frame regardless of whether
2082 the shared libs work.
2083 * ieee-float.c (double_to_ieee_extended): Get exponent from
2084 right place in little-endian systems. From John Carey.
2085
2086 Thu Aug 15 18:43:57 1991 John Gilmore (gnu at cygint.cygnus.com)
2087
2088 * main.c: Remove unused terminating_signals and catch_termination().
2089 (long_options): Terminate with a zero element.
2090 [Bugfix from Atsuo Kawaguchi <atsuo@hark86.harl.hitachi.co.jp>.]
2091 (gdb_readline): Make call-compatible with readline.
2092 (init_signals): Improve comments re vfork vs. signal.
2093
2094 * utils.c (prompt_for_continue): Use new gdb_readline().
2095 If we prompt for continuation, we don't let CR repeat the previous
2096 command, once we get back to a prompt. It's too easy to keep
2097 hitting CR, expecting "--more--" prompts, and have some long
2098 command start repeating on you.
2099
2100 Tue Aug 13 16:17:56 1991 John Gilmore (gnu at cygint.cygnus.com)
2101
2102 * blockframe.c (frameless_look_for_prologue): Speed up by
2103 calling SKIP_PROLOGUE_FRAMELESS_P if it's defined.
2104 * tm-sparc.h (SKIP_PROLOGUE, SKIP_PROLOGUE_FRAMELESS_P):
2105 Define two variants, one faster.
2106 * sparc-tdep.c (sparc_frame_chain): Use target_read_memory
2107 and return zero, rather than giving an error.
2108 (setup_arbitrary_frame): Initialize the PC in the new frame.
2109 (skip_prologue): Add a second arg saying whether we're just
2110 checking for a frameless function or not.
2111
2112 * core.c (core_open, core_close, core_xfer_memory): Move
2113 section table pointers and bfd* into the target_ops.
2114 (core_open): Allow errors in shared lib reading, etc.
2115 (core_files_info): Describe shared library sections.
2116
2117 * exec.c (exec_open, exec_close, exec_xfer_memory, xfer_memory,
2118 exec_files_info, set_section_command): Move section table
2119 pointers and bfd* into the target_ops.
2120 (add_to_section_table): Add BFD to section table.
2121
2122 * target.c (target_xfer_memory, target_info): Pass target to
2123 xfer_memory and target_info functions.
2124 * target.h: ''
2125
2126 * gdbcore.h: Move struct section_table.
2127 * target.h: New home of struct section_table.
2128
2129 * solib.c (solib_add): New argument is the target_ops whose
2130 section list is to be added to, if any. Reallocate the
2131 sections in that target to add any that come from shared libs.
2132 (throughout) so_sections renamed to sections.
2133 (solib_xfer_memory): Deleted.
2134 * tm-sunos.h (SOLIB_ADD): Add target argument.
2135 (SOLIB_XFER_MEMORY): Delete.
2136
2137 * core.c, exec.c, inftarg.c, remote-eb.c, remote-nindy.c,
2138 remote-vx.c, remote.c, target.c, target.h: Remove add_syms vector
2139 from target_ops. It's the same on all targets. Add two section
2140 pointers to target_ops.
2141
2142 * stack.c (find_relative_frame): Dump ancient algorithm for
2143 "down", just use handy "next" pointers.
2144 (frame_command): Don't error if there is no stack; let user
2145 set one.
2146
2147 * inflow.c (new_tty_prefork, new_tty): New prefork routine
2148 modifies static state in the parent process; new_tty itself
2149 runs in the child and modifies the child's file descriptors
2150 to match the saved static state.
2151 * infrun.c (child_create_inferior): Call new_tty_prefork,
2152 fork, then new_tty.
2153
2154 * infptrace.c (child_xfer_memory): Add ignored target arg.
2155 * remote-eb.c (eb_xfer_inferior_memory): ''
2156 * remote-nindy.c (nindy_xfer_inferior_memory): ''
2157 * remote-vx.c (vx_xfer_memory): ''
2158 * remote.c (remote_xfer_memory): ''. Rename from
2159 remote_xfer_inferior_memory.
2160
2161 * main.c (main): Only try to attach "corefile" argument if
2162 it starts with a digit.
2163
2164 * symfile.c (symbol_reloading): New "set/show" variable.
2165 (symbol_file_add): Shorten message about symbol reading.
2166 (add_symbol_file_command): Merge with add_syms_addr_command,
2167 since this should work on all targets now.
2168 (stop_whining): Default to zero, to shut up complaints
2169 about bad symbol tables on many systems.
2170 (free_named_symtabs): Just exit unless symbol_reloading.
2171
2172 * xm-sun3os4.h, xm-sun4os4.h: Define BROKEN_LARGE_ALLOCA,
2173 and add comment explaining shared library screw.
2174
2175 * source.c: #if defined => #ifdef.
2176
2177 Thu Aug 8 12:23:19 1991 John Gilmore (gnu at cygint.cygnus.com)
2178
2179 * doc/gdbint.texinfo: Improve doc on porting to new OS's.
2180
2181 Tue Aug 6 17:16:15 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
2182
2183 * doc/rdl-apps.texinfo: provide default readline-appendix finder
2184 (doc/Makefile knows how to make one for local config)
2185
2186 * Makefile.in: use doc/Makefile for doc targets
2187
2188 * doc/Makefile: GDB documentation now has its own Makefile
2189 doc/refcard.tex: renamed from "gdbrc.tex"
2190 doc/.Sanitize: add Makefile; recognize renamed refcard.tex
2191 doc/gdbint.texinfo: add markup in "Cleanups" chapter
2192
2193
2194 Fri Aug 2 00:13:06 1991 John Gilmore (gnu at cygint.cygnus.com)
2195
2196 * values.c (baseclass_addr): When reading target memory, use the
2197 length of the basetype, not the upper type. We've only malloc'd
2198 enough space for the basetype, leading to errors in free().
2199
2200 * expprint.c (print_subexp): Print UNOP_MEMVAL of an OP_LONG that
2201 ends up as a function specially, since we know the actual type of
2202 the pointed-to address. This (somewhat) fixes display of
2203 expressions that include misc_function_vector names. Try `cond 1
2204 !strcmp("a","b")' then `i b'.
2205
2206 * infrun.c: Move DO_DEFERRED_STORES from proceed() to resume().
2207 The child can be proceeded from inside wait_for_inferior in
2208 evaluating breakpoint conditions, and DO_DEFERRED_STORES was
2209 getting skipped in that case.
2210
2211 * expprint.c (print_subexp): Use filtered output, since the
2212 subroutines we call use it, otherwise the output is horribly
2213 mangled, since output of wrappable stuff comes out late.
2214
2215 * Makefile.in: Bump VERSION to 3.98.1
2216
2217 * infrun.c (child_create_process): Use execlp to find the
2218 shell to exec our target program. This requires some fiddling
2219 with `environ' since there is no execlpe().
2220
2221 Thu Aug 1 15:35:17 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
2222
2223 * Makefile.in, doc/gdbrc.tex, doc/rc-* (new files):
2224 Minor rearrangement of refcard permits two new make targets--
2225 gdbrc.dvi DVI output for refcard, using CM fonts
2226 gdbrc.ps PostScript refcard, using PS fonts
2227
2228 Wed Jul 31 16:46:21 1991 John Gilmore (gnu at cygint.cygnus.com)
2229
2230 * GDB-3.98 release.
2231
2232 * TODO, Projects, WHATS.NEW, README: Update for gdb-3.98.
2233 * Makefile.in (gdb-all.texinfo): Avoid touching file if M4 dies.
2234
2235 Wed Jul 31 16:35:58 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
2236
2237 * doc/gdb.texinfo: last changes for release.
2238 Minor typo and formatting fixes; incorporated most fixes remaining from
2239 filed mail commenting on earlier drafts.
2240
2241 Added warnings: pipes don't work in run command;
2242 conditions are converse of assertions;
2243 step over fn without debug info goes to next fn;
2244 vars may have "wrong" values near fn entrance, exit
2245
2246 Added example from Kingston on printing repeated nonadjacent values
2247
2248 Added explicit mention that in Emacs gdb mode C-c and C-z are like
2249 shell mode for signals
2250
2251 Renamed "Stepping and Continuing" to "Continuing and Stepping" so it
2252 doesn't sound so much like its parent "Stopping and Continuing"; also
2253 moved entries on continue to top of section, so they don't get lost.
2254
2255 Improved installation directions in appendix, added manual formatting
2256 instructions
2257
2258 Tue Jul 30 17:26:39 1991 John Gilmore (gnu at cygint.cygnus.com)
2259
2260 * configure.in: Remove xm.h and tm.h even if we aren't linking
2261 new ones, so "./configure sun4; ./configure none" does the right
2262 thing. Assume that alldeps.mak and depend are already built in
2263 srcdir, and avoid running "make" (particularly "make depend",
2264 which involves "gcc") from inside configure. Build Makefile
2265 directly rather than building Makefile.conf first.
2266 * configure: Regenerate with above changes.
2267 * Makefile.in: Use $(BISON) to find bison. Roll VERSION
2268 to 3.98. Revise gdb.tar.Z procedure to produce a file
2269 called gdb-$(VERSION).tar.Z but which unpacks into a
2270 directory called "gdb". Move non-source files out of
2271 $(SFILES_SUBDIR). Pretty up alldeps.mak with comments.
2272 (depend): Don't try to do "gcc expread.y".
2273 (expread.o): Update dependencies by hand.
2274
2275 Mon Jul 29 15:21:09 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
2276
2277 * doc/gdb.texinfo:
2278 Fixed a variety of small typos that prevented info from formatting
2279 cleanly; altered too-long heading for GPL Appendix, as discussed
2280 w/RMS; Changed date on cover to July 91.
2281
2282 Fri Jul 26 13:20:02 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
2283
2284 * doc/gdb.texinfo:
2285 (1) Applied some fixes due to comments from Larry Breed (easier ones
2286 through chapsec 5.2)
2287 (2) Eliminated use of @footnote---had my doubts about it anyways, and
2288 it's broken in latest texinfo
2289 (3) Introduced *some* use of [] for optional arguments, where
2290 explanation is not simpler by listing cmd w arg and cmd w/out arg
2291 separately. Still not using @deffn.
2292 (4) Dropped in GPL-2. NOTE: one of GPL-2 or texinfo is broken; a
2293 couple of headings are too long. Need patches to texinfo or revision
2294 to GPL-2.
2295
2296 * Partial update to README (which still needs work for this
2297 release!): (1) use of configure corrected for new script,
2298 (2) "make gdb.dvi" and "make gdb.info" mentioned.
2299
2300 Wed Jul 24 06:44:02 1991 John Gilmore (gnu at cygint.cygnus.com)
2301
2302 * symtab.c (lookup_symbol): Don't complain right off about
2303 no debug symbols; use the misc function vector first.
2304 (list_symbols): Use misc function vector to find symbols
2305 that don't have debug info, and print them.
2306 (find_pc_symtab): Temporarily avoid fatal() when psymtab
2307 PC range doesn't match symtab PC range, as it does on the
2308 MIPS because our symtab reading isn't perfect.
2309
2310 * dbxread.c (dbx_symfile_read): Make warning about
2311 "no debug symbols" slightly nicer.
2312
2313 * source.c (select_source_symtab): If "main" symbol exists,
2314 but decode_line_spec can't find line info, don't just return
2315 a zero; try other source symtabs or give an error.
2316
2317 * mipsread.c (parse_partial_symbols): Sort the psymtabs by
2318 their low addresses first, then rip through fixing high addrs.
2319
2320 * ns32k-opcode.h (sfsr): Bugfix from Rune Nerg}rd,
2321 <runene@ifi.uio.no>.
2322 (NS32K_SVC_IMMED_OPERANDS): Reverse the #ifndef.
2323
2324 Tue Jul 23 18:52:43 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
2325
2326 * Minor, mostly mechanical, cleanup of doc subdir for clean
2327 makeinfo'ing and TeXing; also ensured gdb-all.texinfo (post-m4)
2328 and gdb.info (post- texinfo2 makeinfo) generated for distribution.
2329
2330 Sun Jul 21 03:54:52 1991 John Gilmore (gnu at cygint.cygnus.com)
2331
2332 Mostly MIPS and general symbol-reading fixups.
2333
2334 * doc/gdbint.texinfo: Add documentation on symbol-reading
2335 interface.
2336
2337 * mipsread.c: Remove kludges around #include "ecoff.h".
2338 Remove redefinitions of a_magic, etc, no longer used.
2339 (parse_symbol, ): Convert "Internal:" printfs to complain()ts.
2340 Fix global overview comments to match symfile.c protocol.
2341 (mipscoff_new_init): Eliminate cur_hdr if we have one.
2342 (mipscoff_symfile_read): Eliminate unused code. Avoid
2343 sorting all the symtabs, when all we have read here is psymtabs.
2344 The symtabs are sorted as they are created anyway. Tell
2345 condense_misc_bunches whether we're mainline.
2346 (psymtab_to_symtab_1): Pass filename when recursing, to make
2347 stack trace more informative.
2348 (parse_partial_symbols): Assume cur_hdr as argument.
2349 (read_mips_symtab): Don't clobber cur_hdr, so it can be freed.
2350 Pass cur_hdr implicitly to parse_partial_symbols. Avoid checking
2351 the TYPE_NAME of char *, since that's done in symfile.c.
2352 (free_numargs, parse_symbol, add_symbol, add_block,
2353 shrink_linetable): Declare these fns void.
2354 (upgrade_type): Convert tree of if's to switch. Clean up
2355 bogus "off == 0" handling with a complaint. Avoid setting
2356 field bitpos and bitsize of array with lower and upper bounds.
2357 Check specified bitsize of elements against their actual type's
2358 bitsize, and complain if different. Complain about unknown
2359 type qualifiers.
2360 (parse_fdr): Don't assume sizeof(char *) == sizeof (struct *).
2361 (psymtab_to_symtab_1): Print names of subsidiary files that
2362 are being read in. FIXME, we read far too many files. This code
2363 is not the problem, the problem is in parse_fdr where the psymtabs
2364 are set up.
2365 (cross_ref): Result should indicate that we used one aux entry
2366 normally, or two if we encountered a "next" entry. This used
2367 to leave the caller pointing at the wrong aux entry.
2368 (add_symbol): If overflowed cur_block, reallocate it larger,
2369 chase all pointers to it, and complain(), rather than clobber memory.
2370 (shrink_block): Use xrealloc rather than xmalloc-and-copy.
2371 (new_field): Only allocate one field initially, not two.
2372 Pull ++ out of macro argument. Simplify.
2373 (_initialize_mipsread): Avoid initialization of importd
2374 global_psymbols and static_psymbols.
2375
2376 * symfile.c (psymtab_to_symtab): Depend on XXX_psymtab_to_symtab
2377 to properly set pst->symtab; avoid searching for it.
2378 (symfile_fns): Improve comments, add a FIXME.
2379 * dbxread.c: Update comments to reflect symfile protocol.
2380 (read_ofile_symtab, end_symtab): Return the symtab.
2381 (psymtab_to_symtab_1): Set pst->symtab.
2382
2383 * coffread.c (coff_symfile_read): tell condense_misc_bunches
2384 whether we're mainline.
2385
2386 * symfile.h (sym_fns): Remove unused sym_discard member.
2387 * coffread.c, mipsread.c, dbxread.c: Remove XXX_symfile_discard.
2388
2389 * mtrace.c (mtrace): Take effect if mallwatch is set, even if
2390 the environment variable is not.
2391 * infcmd.c (finish_command): Use filtered printfs.
2392 * cplus-dem.c: Add struct tags to a few unnamed structs.
2393 * valops.c (value_coerce_array): Improve comments.
2394 * valprint.c (type_print_varspec_suffix): Print array size only
2395 if greater than zero.
2396 * m88k-tdep.c: Shift some lines left by one space, that had
2397 apparently been trashed at some point.
2398 * TODO: More things to do, a few got done.
2399
2400 Thu Jul 18 22:46:05 1991 John Gilmore (gnu at cygint.cygnus.com)
2401
2402 * symtab.h (LOC_EXTERNAL): Eliminate in favor of LOC_STATIC.
2403 (ldsymoff, ldsymlen, globals_offset, statics_offset): Improve
2404 comments.
2405 * dbxread.c (read_dbx_symtab): LOC_EXTERNAL -> LOC_STATIC.
2406 * expread.y, findvar.c, symmisc.c: Ditto.
2407 * printcmd.c (address_info): Update printed forms of LOC_
2408 symbols. Elim LOC_EXTERNAL.
2409 (print_frame_args): Keep track of param stack offsets before
2410 re-looking up to find the local register param is kept in.
2411
2412 * mipsread.c: Use <symconst.h> and <sym.h> rather than <syms.h>.
2413 Further integration of mipsread into gdb. Eliminate unused
2414 routines, duplicate declarations. Handle static symbols in
2415 psymtabs as well as external symbols. When reading symtabs,
2416 insert symbols into the correct block (global, static, or a local
2417 block).
2418 (read_mips_symtab, parse_partial_symbols): Don't pass useless
2419 "incremental" arg.
2420 (mipscoff_symfile_read): Don't call select_source_symtab.
2421 (parse_symbol): Use SYMBOL_VALUE_ADDRESS where appropriate,
2422 rather than SYMBOL_VALUE.
2423 (parse_external): Comment clobbering of top_stack.
2424 (parse_partial_symbols): Update comments. Allocate and parse
2425 static symbols as well as external symbols. FIXME, enum values
2426 are not handled in this pass, but should be. Inline new_psymbol.
2427 Use SYMBOL_VALUE_ADDRESS.
2428 (psymtab_to_symtab_1): Read symbols into global static block
2429 by default (until enter some function's local block context).
2430 (sort_blocks): Clean up STATIC_BLOCK as well as GLOBAL_BLOCK.
2431 (destroy_all_symtabs, new_psymbol): Eliminate, unused.
2432
2433 * source.c (select_source_symtab): Select a source symtab
2434 from either the symtabs or, failing that, the psymtabs.
2435 (list_command): Update error message.
2436 (forward_search_command, reverse_search_command): Use getc, not
2437 fgetc, for speed. FIXME, add comment about buffers that die if
2438 overrun by long line.
2439
2440 * values.c (unpack_field_as_long, modify_field): Avoid shifting
2441 by an entire word, which is not portable, if we have a 32-bit
2442 field. (Code in dbxread.c already turns such bitfields, if
2443 aligned, into ordinary ints, but fixing this will help for other
2444 symbol formats and for future changes.)
2445 * core.c (core_open): Handle ANSI const brain death.
2446 * utils.c (vprintf): Fix varargs typo.
2447
2448 Sun Jul 14 00:42:53 1991 John Gilmore (gnu at cygint.cygnus.com)
2449
2450 * findvar.c (find_var_value): Handle &function better.
2451 * TODO: Document work needed on &fn and &array.
2452 * printcmd.c (print_address_symbolic): New arg is the prefix
2453 to print if a name is printed.
2454 (print_address_demangle): Honor "set print address" now.
2455 Use new arg above to improve spacing of output.
2456 * valprint.c (val_print): When printing function pointers,
2457 print symbolic form too.
2458 * breakpoint.c (breakpoint_1): Use new print_address_symbolic.
2459
2460 Mon Jul 8 19:02:46 1991 John Gilmore (gnu at cygint.cygnus.com)
2461
2462 * core.c (memory_error): Reword error msg to mislead less.
2463
2464 * mips-pinsn.c (print_insn_arg 'd'): Print $ with reg name.
2465
2466 * mipsread.c (read_mips_symtab, read_the_mips_symtab,
2467 parse_partial_symbols): Use newer BFD internals (external_filehdr
2468 and external_aouthdr), byte-swap the fields that we care about
2469 before using them, and make the file header data local to
2470 read_the_mips_symtab rather than global.
2471
2472 Sat Jul 6 01:34:15 1991 John Gilmore (gnu at cygint.cygnus.com)
2473
2474 * ns32k-opcode.h (movmw, movmd): Fix opcodes. Bug fix
2475 from Rune Nerg}rd <runene@ifi.uio.no> on 5 Jul 1991.
2476
2477 * main.c (command_line_input): Flush stdout and stderr
2478 before every call to readline. This reportedly fixes a bug
2479 that comes up in Sys V running emacs-gdb and/or xxgdb,
2480 when stdin/out are pipes or sockets.
2481
2482 Thu Jul 4 14:47:06 1991 John Gilmore (gnu at cygint.cygnus.com)
2483
2484 * configure.in, Makefile.in: Avoid rebuilding "depend" as much.
2485 Avoid declaring Makefile dependencies, because GNU Make stupidly
2486 tries to update it if we do.
2487
2488 * coffread.c: Revise for minor changes to bfd internal coff
2489 indexes.
2490
2491 * configure: If -template= is given a relative path, make it
2492 absolute before recurring in subdirectories.
2493
2494 * configure, configure.in, Makefile.in: Install "configure" script
2495 as replacement for config.gdb.
2496 * config.gdb, Makefile.dist, Makefile.sdir: Remove
2497 * README: Update for configure, mostly. FIXME.
2498
2499 * Add dec3100 as equivalent to littlemips. Indicate in all host &
2500 target config files that they are for the host. When the lines
2501 get copied into the Makefile, this makes it more obvious what's
2502 up.
2503
2504 Mon Jun 24 23:49:07 1991 John Gilmore (gnu at cygint.cygnus.com)
2505
2506 * sparc-opcode.h (trap opcodes): Avoid leading spaces or
2507 tabs, which end up in the disassembler output inadvertently.
2508
2509 Wed May 29 23:01:03 1991 John Gilmore (gnu at cygint.cygnus.com)
2510
2511 Make it compile cleanly in an ANSI GCC2 environment.
2512
2513 * blockframe.c: <stdio.h>
2514 * cplus-dem.c: free takes a void *, ifdef __STDC__
2515 * dbxread.c (read_huge_number): avoid gcc2 bug hoisting calc of
2516 LONG_MAX/radix.
2517 * defs.h (alloca): Avoid doing anything if alloca already def'd.
2518 * stddef.h, stdlib.h: Remove these files.
2519 * symtab.c: Avoid declaring qsort, close.
2520 * symfile.c: Avoid declaring close.
2521 * utils.c (vprintf): Declare "ap" arg as proper va_alist.
2522 * sparc-tdep.c: Avoid including lots of Sun-host-specific files.
2523
2524 Assorted other changes.
2525 * dbxread.c: include "libaout.h", not "liba.out.h".
2526 * printcmd.c (print_frame_args): Set recurse properly for
2527 indentation of struct and array parameters.
2528 * valops.c (value_cast): Allow cast to void.
2529 * infrun.c (resume): If NO_SINGLE_STEP, call machine dependent
2530 single_step() in a target-independent fashion.
2531 * sparc-tdep.c (single_step): Don't call ptrace ourselves, just
2532 set up to be ready to continue. This makes us target independent.
2533 * infptrace.c (child_resume): Remove call to single_step; now
2534 can single step a SPARC target of any kind.
2535
2536 Wed May 22 18:18:24 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
2537
2538 * Makefile.dist, doc/gdb.texinfo, doc/*-m4.texinfo: split up GDB
2539 docn into separate sections---basically chapters, plus two loose
2540 pieces that can be configured to go in different places. This
2541 allows GNU m4 to preprocess the manual without coredumping.
2542
2543 * Makefile.dist: tell TeX where to find texinfo.
2544
2545 Mon May 20 12:15:04 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
2546
2547 * Makefile.dist, doc/gdb.texinfo: respectively create, and use,
2548 the new target "rdl-apps.texinfo" which captures the Makefile
2549 variable that records where to find the Readline libraries.
2550
2551 Sun May 19 05:36:59 1991 John Gilmore (gnu at cygint.cygnus.com)
2552
2553 * tahoe-pinsn.c: #include "tahoe-opcode.h", not "opcode.h".
2554 * tm-tahoe.h (FIX_CALL_DUMMY): Ignore more parameters.
2555 * defs.h (const, volatile): Only define if not already defined.
2556 * Makefile.dist (gdb.tar.Z): Create doc subdir w/out CVS/RCS crud.
2557
2558 * README: Update for release 3.95.
2559 * config.gdb: Don't create readline dir in subdir builds.
2560 * main.c: Include with "..." form for non-system include files,
2561 so "gcc -MM" for "make depend" works.
2562 Include readline files with "...h" rather than <readline/...h>.
2563 * mipsread.c: Include "ecoff.h" rather than "intel-coff.h".
2564
2565 * coffread.c: Undo minor damage done by Rich Pixley. Use
2566 different internal and external representations of COFF
2567 data structures. Use new BFD routines for swapping them in and
2568 out.
2569 * symfile.c (free_named_symtabs): Avoid freeing file names that
2570 are null or empty. Old i960 tools seem to produce files that
2571 claim to have empty names, causing each successive file read
2572 to blow away the previous one.
2573 * sparc-xdep.c (deferred_stores): Repair minor damage by Rich.
2574 Move deferred_stores to top of file, but don't separate its
2575 #define's from its variable. Add commentary.
2576 * Makefile.dist: Fix Rich damage; undo "configure" changes in
2577 favor of keeping the (working) config.gdb. Move readline
2578 library up a notch.
2579
2580 Fri May 17 12:49:56 1991 Per Bothner (via gnu at cygint.cygnus.com)
2581
2582 * dbxread.c (read_struct_type): Try to handle g++ version 1 MI
2583 debug info.
2584 * infptrace.c (fetch_registers): no result, since now void.
2585 * tconfig/news: target depends on m68k-tdep too.
2586
2587 Fri May 17 14:40:14 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
2588
2589 * Makefile.dist: added readline/inc-*.texinfo to dependencies for
2590 gdb.dvi target
2591
2592 * readline/inc-history.texinfo, readline/inc-readline.texinfo:
2593 applied various small fixes due to or inspired by RMS comments
2594
2595 * doc/gdb.texinfo: finished using all RMS comments, save those for
2596 appendices on readline and cmd history (which are in other source
2597 files)
2598
2599 Thu May 16 18:06:05 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
2600
2601 * doc/gdb.texinfo: (1) Updated w/ref to RMS comments through
2602 chapter 9; (2) documented 'break' command's menu mode for
2603 overloaded names, in response to hgs problem report C++ p-31
2604
2605 Wed May 15 11:02:48 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
2606
2607 * doc/gdb.texinfo: (1) better introductory example; (2) more
2608 consistent use of @code, @samp, @file, @kbd throughout; small
2609 cleanups to first three nodes; (3) new "Contributors" node;
2610 (4) Appendix, Renamed Commands; (5) divert specialized startup
2611 instructions to "Targets" chapter for generic manuals, while
2612 leaving them up front for manuals specific to specialized
2613 environments; (6) apply fixes from RMS comments through chapter 4.
2614
2615 * pretex.m4: modify explanatory text slightly (and redefine
2616 "regexp") to keep GNU m4 from complaining. (It still crashes
2617 later, but one step at a time...)
2618
2619 Wed May 15 10:32:12 1991 John Gilmore (gnu at cygint.cygnus.com)
2620
2621 * readline/readline.c (update_line): Avoid dereferencing a pointer
2622 before comparing it to its bounds. Saber caught this.
2623 (init_terminal_io): Don't set BC from the "pc=" termcap variable,
2624 and only set PC if tgetstr returned non-null. Saber caught this.
2625
2626 Tue May 14 16:29:53 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)
2627
2628 * Makefile.dist: put gdb.dvi stuff (updated to use M4 preprocessor
2629 stuff for config manual) here where it counts; updated
2630 to use new subdir structure (gdb/doc/).
2631
2632 * Makefile: generated from above via
2633 config.gdb none
2634 before checkin
2635
2636 * gdbint.texinfo: added instructions on generating gdb.info* files
2637 locally for release. These are ordinary info
2638 files, formatted from gdb.texinfo (via gdb-all.texinfo, see
2639 Makefile)---but due to use of texinfo 2, can't count on makeinfo
2640 to generate these, so we distribute them already formatted.
2641
2642 * gdb.texinfo: included full Info node and menu crud (as generated
2643 by C-u M-x texinfo-master-menu using the texinfo-2 elisp code).
2644
2645 * Makefile: updated "gdb.dvi" target to use M4 preprocessor;
2646 put in comments-for-future gdb.info target (one day makeinfo will
2647 work again).
2648
2649 Tue May 14 13:51:36 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)
2650
2651 * gdb.texinfo: Updated to include new or old undocumented
2652 commands, at least the following (perhaps some others I forgot to
2653 record): info f, info float, info path, info program, info s, info
2654 set, info source, info terminal, info types, info user, set/show
2655 print object.
2656 Also covered all recent GDB command renames for v4.
2657
2658 Mon May 13 14:57:46 1991 John Gilmore (gnu at cygint.cygnus.com)
2659
2660 * mipsread.c: Rather than keeping count of how many symtabs
2661 and psymtabs we have, for sorting purposes, count them when
2662 we need to sort. This fixes bug in rereading of symbol tables.
2663
2664 Fri May 10 15:43:33 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)
2665

2682 * core.c: setup and select frame after reading shared libs,
2683 else reading shared libs will clobber them. Lint.
2684 * utils.c (error): Force out any buffered wrap text.
2685
2686 Fri May 3 22:01:56 1991 John Gilmore (gnu at cygint.cygnus.com)
2687
2688 * remote.c: Remove decls of memory_insert_breakpoint
2689 and memory_remove_breakpoint, no longer used. (Suggestion of
2690 Jan Norden).
2691
2692 * Makefile.dist: use ${subdir} in paths of BFD and LIBIBERTY,
2693 to make it easier to interface to "configure"'d libraries.
2694
2695 Fri May 3 13:10:01 PDT 1991 Roland Pesch (pesch at fowanton.cygnus.com)
2696

3248
3249 * dbxread.c (read_dbx_symtab): Allow N_SOL to cleanly take us back

3251 functions into the global psymtab, to make "i fun" work.
3252 (end_psymtab): Free named symtabs and psymtabs for a file, once a
3253 new psymtab for it has been read.
3254 * coffread.c (end_psymtab): Free named symtabs and psymtabs for
3255 a file, once a new symtab has been read for it.
3256 * mipsread.c: FIXME. We need to do the same for MIPS, but it
3257 looks harder to determine the top-level block before it's been
3258 queued to the psymtab list.
3259
3260 * symfile.c (symbol_file_add): Use filtered printing and wrap it.
3261 If we have wiped out any old symbol tables, clean up at end of

3264
3265 * symtab.h (GLOBAL_BLOCK, STATIC_BLOCK, FIRST_LOCAL_BLOCK): New

3275
3276 * symtab.c (list_symbols): Process the first symbol of the
3277 static psymbols list.
3278 (types_info): Restore this function from its untimely #if 0.
3279 It's not perfect, but it is better than nothing.

3281
3282 Thu Apr 11 05:23:19 1991 John Gilmore (gnu at cygint.cygnus.com)
3283
3284 * m68k-stub.c: Remote stub for 680x0's, created from

3287 Remove RCS log stuff now that we use CVS and it blows our diffs.
3288
3289 Wed Apr 10 14:18:06 1991 John Gilmore (gnu at cygint.cygnus.com)
3290
3291 * symmisc.c (free_named_symtab): Make it work, in its current
3292 kludgy fashion. Change result to indicate if we blew away bkpts.

3294 free_named_symtab and print warning if we blew user's state.
3295 * symfile.h: free_named_symtab now returns an int.
3296
3297 Mon Apr 8 23:57:43 1991 John Gilmore (gnu at cygint.cygnus.com)
3298
3299 * dbxread.c (dbx_symfile_read): Initialize psymbol list if this
3300 is the first symbol read, even if not mainline.
3301 (dbx_psymtab_to_symtab): symfile might be zero, cope.
3302 * exec.c (exec_ops): Add_syms_addr is valid in our tvec.
3303 (set_section_command): New command ("section xxx yyy" -- should
3304 be renamed to "set section xxx yyy" FIXME) which sets the
3305 base address of a section of the exec file, overriding the
3306 virtual address that BFD reports.
3307
3308 Fri Apr 5 17:14:39 1991 John Gilmore (gnu at cygint.cygnus.com)
3309
3310 * exec.c: Add add_syms_addr_command to exec_ops, so you can
3311 load symbols at any address while examining an exec file.
3312
3313 Thu Apr 4 10:09:35 1991 John Gilmore (gnu at cygint.cygnus.com)
3314
3315 * tm-i386v.h (FLOAT_INFO): Don't define it, since the code
3316 for printing the float info is host-dependent, not
3317 target-dependent. FIXME.
3318 * i386-pinsn.c: Move #includes to top, remove useless ones.
3319 * i386-tdep.c: Don't bother including <.../reg.h> since we
3320 don't use it (and it doesn't exist on host systems).
3321
3322 * ieee-float.c (ieee_extended_to_double): Convert NaN to Inf.
3323 Convert negative numbers properly.
3324 (ieee_test): Make numbers really random; fix format arg.
3325
3326 * infcmd.c (attach_command, detach_command): Don't repeat on CR.
3327 * core.c (core_detach): Unpush core_ops, which might not be on
3328 top. We used to just pop the top, which broke things. Don't
3329 need dont_repeat() any more.
3330 (core_file_command): Psst! Don't repeat it.
3331 * remote-nindy.c (nindy_detach): Don't need dont_repeat() now.
3332 * expprint.c (print_subexp): Avoid switch fallthru on
3333 BINOP_ASSIGN_MODIFY, so we can print += and such.
3334 * frame.h: Fix typo.
3335 * inflow.c (kill_command): After killing inferior, print our
3336 current frame in the core file, if we have one.
3337 (generic_mourn_inferior): When inferior dies, either select
3338 the current frame (in the new target, e.g. core file), or
3339 set both the current and selected frames to NULL.
3340
3341 Changes from Peter Schauer.
3342
3343 * infptrace.c: Avoid <sys/ptrace.h> on USG.
3344
3345 * Make all file names fit in 14 characters (sigh and damn!):
3346 mv hp300hpux-xdep.c hp300ux-xdep.c
3347 mv symmetry-xdep.c symm-xdep.c
3348 mv symmetry-tdep.c symm-tdep.c
3349 mv convex-opcode.h convx-opcode.h
3350 mv tm-vxworks960.h tm-vx960.h
3351 mv tm-vxworks68.h tm-vx68.h
3352 mv Makefile.srcdir Makefile.sdir
3353 mv gdb-int.texinfo gdbint.texinfo
3354 mv remote-sa.m68k.shar rem-m68k.shar
3355 mv remote-multi.shar rem-multi.shar
3356 * Makefile.dist, README, config.gdb, convex-pinsn.c,
3357 tconfig/symmetry, tconfig/vxworks960, tconfig/vxworks68,
3358 xconfig/hp300hpux, xconfig/symmetry: Change names to shorter
3359 names.
3360
3361 * command.c (user_info_1, user_info): New command for listing
3362 the user-defined commands.
3363
3364 Wed Apr 3 15:00:26 1991 John Gilmore (gnu at cygint.cygnus.com)
3365
3366 * dbxread.c (really_free_pendings): Clear file_symbols
3367 and global_symbols after freeing them; otherwise, running
3368 this function twice (if it appears twice on the cleanup
3369 chain), we try to free things twice.
3370
3371 * dbxread.c (read_dbx_symtab): Calculate end_of_text_addr
3372 based on text_addr (the address of text in core), not on addr (the
3373 offset between text in the .o file and in core). This change
3374 is from Peter Schauer.
3375
3376 * main.c: Define ALL_CLEANUPS as a cast of zero.
3377 (return_to_top_level): Use it.
3378 (main): Do all cleanups after each command run as part
3379 of the gdb startup sequence. Also do all cleanups before
3380 entering the command loop, and every time we exit the command
3381 loop and reenter. Before, the cleanups from the startup sequence
3382 were being left undone until the first error!
3383 (command_loop): Rename do_nothing cleanup to command_loop_marker
3384 so we can see it easily when examining the cleanup chain.
3385 (init_signals): Add another do_nothing for signal handling.
3386 (quit_command): Only try to kill target if it has execution.
3387 Problems in the target stack got us into a state where
3388 inferior_pid was nonzero but none of the targets had execution.
3389 In this state you couldn't exit gdb.
3390
3391 * dbxread.c: Two changes from Peter Schauer.
3392 (echo_command): Fflush output after an echo command.
3393 (show_history): Pass all args to cmd_show_list.
3394
3395 * utils.c (init_malloc): Call mtrace to turn on tracing
3396 if the environment variable MALLOC_TRACE is set to a file name.
3397 * mtrace.c: Add source file which provides a log of every malloc,
3398 free, and realloc to a trace file.
3399 * mtrace.awk: Add source file which analyzes the trace file.
3400 * Makefile.dist (GNU_MALLOC, MALLOCSRC): Add mtrace.{c,o,awk}.
3401 (VERSION): Roll to 3.94.3.
3402
3403 * breakpoint.c (breakpoint_1): Add a space to "i watch" output.
3404 (check_duplicates): Don't bother with watchpoints.
3405 (set_raw_breakpoint): Comment about danger of this routine.
3406 (watch_command): Parse and eval all args before calling
3407 set_raw_breakpoint.
3408
3409 * solib.c (find_solib): Avoid error in referencing memory to
3410 see if any more shared libraries have been added. This is
3411 particularly useful if the target has terminated. Bug reported
3412 by Peter Schauer.
3413
3414 Changes from Peter Schauer <pesrem@regent.e-technik.tu-muenchen.de>
3415 in bringing up 3.94.2 on the Sun-3.
3416
3417 * Makefile.dist: Include CFLAGS in rule for cplus-dem.o.
3418 * breakpoint.c (enable_breakpoint): Check for valid watchpoint
3419 expression (in scope) before reenabling watchpoint.
3420 * signame.c (init_sigs): Add missing declaration of i, fix
3421 sys_siglist declaration.
3422 * source.c (list_command): Fixed range computation to use
3423 lines_to_list ().
3424 * stack.c (backtrace_command): Do not allow command if target has
3425 no stack, print informative error message.
3426 * target.c (target_command): Do not write into command line
3427 because this fails if the target command is used in a user defined
3428 command. [This change was enhanced by gnu to support any-
3429 unique-prefix matching on target names.]
3430 * valops.c (value_struct_elt): Avoid infinite loop on an
3431 erroneous attempt to print the member of function (try p main.p).
3432
3433 Mon Apr 1 17:05:45 1991 John Gilmore (gnu at cygint.cygnus.com)
3434
3435 * expread.y (name_no_typename): Avoid reduce/reduce errors
3436 caused by ambiguity in handling NAME_OR_INT and NAME_OR_UINT.
3437 Since the GDB parser really doesn't use name_no_typename in a
3438 name-only context, the parser can't tell the diff between
3439 names and numbers here. Avoid allowing a name_no_typename
3440 to be a NAME_OR_*INT to resolve the conflict.
3441
3442 Sun Mar 31 20:12:07 1991 John Gilmore (gnu at cygint.cygnus.com)
3443
3444 Bugfixes from Mark Fox (markf@wrs.com) (test=testField.c):
3445
3446 * valprint.c (val_print_fields): bitfield printing didn't handle
3447 byte order. Indirect through a few more fns to cope.
3448
3449 * values.c (modify_field): also cope with byte order.
3450
3451 Sat Mar 23 10:02:21 1991 John Gilmore (gnu at cygint.cygnus.com)
3452
3453 Cleanup for release 3.94.2:
3454
3455 * Makefile.dist: Pull REMOTE_OBS. Fix saber includes for BFD
3456 include files. Roll version to 3.94.2.
3457
3458 * coffread.c (init_stringtab): Read length into unsigned char
3459 array before swapping; don't assume 32-bit longs.
3460
3461 * target.c (target_info): Don't bother with get_sym_file, just use
3462 the symfile global variable.
3463 * symtab.h, symfile.c (get_sym_file): Delete it.
3464
3465 * dbxread.c (dbx_symfile_init): Don't depend on long == 4 bytes.
3466 (define_symbol): Set symbol line number to 0 if not gcc-compiled.
3467 (read_type): Replace one more error() with complain().
3468
3469 * mipsread.c (parse_partial_symbols): Replace printf with complain.
3470
3471 * i960-tdep.c: Fix copyright attribution.
3472
3473 * config.gdb: Quote all backquotes in doublequotes. You can
3474 quote me on that. BSD 4.4 shell found this one.
3475
3476 * infptrace.c (throughout): The third argument to ptrace is an
3477 int *, not an int.
3478
3479 * infrun.c (wait_for_inferior): When program has terminated, we
3480 have to call target_terminal_ours before we pop that target off
3481 the stack (e.g. before a call to target_kill or
3482 target_mourn_inferior). This fixes problem where a program
3483 terminates, then GDB stops for (tty output) and you have to type
3484 "fg" to the shell to resume it. FIXME: This code for what to
3485 do after termination really should be in normal_stop instead.
3486
3487 * gdbcore.h (read_memory_check): Change declaration; it changed
3488 names months ago.
3489
3490 * terminal.h: Include <sgtty.h> before <sys/ioctl.h>, since in BSD
3491 4.4 prereleases, this avoids a bug in their sgtty compatability
3492 support.
3493 * remote.c: Use terminal.h rather than hand-rolling the same.
3494
3495 * signame.c, signame.h (psignal): Arg is unsigned, not int.
3496 * utils.c (strsave, strstr): Fix arg types.
3497 * valprint.c (val_print): lint
3498
3499 MIPS symbol table support from Per Bothner:
3500
3501 * symfile.c (symtab_fns): Remove initializer table that needs to
3502 be hacked for each new symbol file format supported.
3503 (add_symtab_fns): New function, chains symbol table
3504 handlers into the global list.
3505 (symfile_init): Search this list.
3506 * symfile.h: Add next pointer, declare add_symtab_fns.
3507 * coffread.c (_initialize_coffread): Call add_symtab_fns.
3508 * dbxread.c (_initialize_dbxread): Call add_symtab_fns.
3509
3510 * mipsread.c (psymtab_to_symtab_1): return void instead of (struct
3511 symbol *). Thus, we no longer need the hack to trash
3512 pst->filename. Good, since that hack confused code in symfile.c!
3513
3514 (reorder_symtabs, destroy_all_symtabs): Removed static
3515 all_symtabs, which was used to qsort symtabs in reorder_symtabs.
3516 Instead, the latter now uses a temporary array (stack-allocated
3517 from an obstack, and then freed).
3518
3519 (parse_symbol): Added a hack to fix up BLOCK_{START,END} if they
3520 haven't been set in the outermost stBlock of a procedure. This was
3521 a problem with f77 binaries on Ultrix 4.?.
3522
3523 (new_symtab, new_symbol, new_type): Continue changing code to use
3524 obstacks more and otherwise conform to dbxread internal style.
3525 Made the free_code of symtabs be free_linetable (as in dbxread)
3526 instead of free_contents. This implies memory leaks when reading
3527 a new symbol table, until the conversion is finished. Did change
3528 (struct symbol) and (struct type) to be allocated on the
3529 symbol_obstack. Blocks and blockvectors are among the things
3530 still "leaking."
3531
3532 * mipsread.c (parse_partial_symbols, parse_fdr): It hasn't been
3533 tested much, but it solved one problem (reported by Meissner), and
3534 cleans up some other things. The problem happened when an
3535 included file contains actual code (functions) and not just
3536 definitions. The mips coff is a little inconvenient there, since
3537 it may cause a procedure to be mapped to the wrong psymtab.
3538
3539 * mips-tdep.c (heuristic_proc_desc): Minor cleanup.
3540 * mips-xdep.c (fetch_core_registers): Minor cleanup. FIXME,
3541 this will need work for the new core paradigm.
3542
3543 Opcode patches from the net:
3544
3545 * mips-opcode.h: fix incorrect disassembly of the mfc1, cfc1, and
3546 ctc1 instructions. Also, the cvt.d.w and cvt.s.w instructions were
3547 missing altogether - they are added here. From Bruce Bauman.
3548 * mips-opcode.h: The low mask for C0 instructions was too small.
3549 From Garrett Lau. I modified the fix to check the entire 32-bit
3550 opcode.
3551
3552 * ns32k-opcode.h: Fix opcodes for deiw and deid. From Bruce
3553 Bauman.
3554
3555 Thu Mar 21 12:56:46 1991 John Gilmore (gnu at cygint.cygnus.com)
3556
3557 Roll in changes from Per Bothner (Tue, 25 Sep 90 11:11:04):
3558
3559 * dbxread.c (read_type): Pointer subtraction (value_sub in
3560 valarith.c) sometimes failed because the types of the
3561 pointers being subtracted were not identical.
3562 These differed because dbxread.c was allocating pointer types
3563 using dbx_alloc_type+smash_to_pointer_type instead of
3564 lookup_pointer_type. I failed to find a justification for the
3565 former, so I changed it to use the latter. Similarly, I
3566 replaced smash_to_function_type by lookup_function_type,
3567 and smash_to_reference_type by lookup_reference_type.
3568
3569 * mipsread.c (parse_symbol, upgrade_type, parse_procedure,
3570 _initialize_mipsread): corresponding changes.
3571
3572 * symtab.c (smash_to_{pointer,reference,function}_type): eliminate.
3573
3574 * source.c (mod_path): Do tilde_expand on each component of the path,
3575 rather than on the (list of) paths as a whole.
3576 (print_source_lines): Set first_line_listed in addition to
3577 current_source_symtab and current_source_line. If the source was
3578 not findable, after a "dir" command to fix the problem,
3579 a "list" would get the wrong lines.
3580
3581 While I was there... (gnu):
3582
3583 * dbxread.c (read_type): Change error to complaint.
3584
3585 Thu Mar 21 12:56:46 1991 John Gilmore (gnu at cygint.cygnus.com)
3586
3587 First attempt at detailed understanding of symbol table memory alloc.
3588
3589 * dbxread.c (dbx_symfile_read): Free our string table if we
3590 aren't the mainline. Free the "info" struct since we're done with
3591 it.
3592 (init_psymbol_list): Free any previously allocated psymbol lists.
3593 (): FIXME: Should realloc-down the psymbol lists when done reading
3594 the main symbol file?
3595
3596 * symmisc.c (free_symtab): Free fullname field too.
3597
3598 * xm-hp300hpux.h (USG): #undef then #define so Makefile can -D.
3599 (REGISTER_ADDR): Make result type unsigned int.
3600
3601 * xconfig/{i386*,hp300hpux,altosgas,altos}: All config files that
3602 define REGEX must also define REGEX1 (its dependency).
3603
3604 Tue Mar 19 21:28:57 1991 John Gilmore (gnu at cygint.cygnus.com)
3605
3606 * tconfig/i960: No longer works, points you at vxworks960 or
3607 nindy960.
3608
3609 * xgdb.c, XGDB-README: Remove file. Users can get the much
3610 better xxgdb.
3611 * Makefile.dist: Remove all trace of xgdb.
3612
3613 * breakpoint.c (breakpoint_1): Pass demangle arg to
3614 print_address_symbolic.
3615 (clear_breakpoints): Remove unused function.
3616 (breakpoint_re_set_one): Guts of breakpoint_re_set.
3617 (breakpoint_re_set): Use catch_errors to do them all anyway.
3618
3619 * gdb-int.texinfo (Host versus Target): Add section on what is
3620 a "host" feature versus what is a "target" feature.
3621
3622 * infcmd.c (path_command, path_info): Handle the PATH variable
3623 (object search path) as conveniently as the source search path.
3624 * environ.c (set_in_environ): Set some vars in GDB's environment,
3625 in addition to the child's. PATH, G960BASE, G960BIN for starters.
3626 * source.c (mod_path): New function, from guts of
3627 directory_command, modifies a path. Used by path_command.
3628 (directory_command): Call it.
3629 * defs.h (strsave): Declare.
3630
3631 * utils.c (sevenbit_strings): Add new printing option.
3632 (printchar): Use it.
3633 (strsave): Provide this handy helper routine.
3634 (set_width_command): Rename set_screen_width_command.
3635 (_initialize_utils): "set screen-width" => "set width";
3636 "set screen-height" => "set height"; add sevenbit-strings.
3637
3638 * infcmd.c (do_registers_info): Print floating point registers
3639 in raw hex as well as float format, regardless of whether it is
3640 a "virtual" convertible register.
3641 * tm-sparc.h (PRINT_REGISTER_HOOK): Print every pair of float
3642 regs as a double, just in case it's being used that way.
3643 * values.c (unpack_long): Comment on array/function coercion.
3644 (unpack_double): Argument is in target byte order now. For
3645 integer arguments, just call unpack_long and float the result.
3646 * m68k-tdep.c: include defs.h for "const" handling.
3647 * remote-nindy.c: Use ieee-float stuff.
3648 (nindy_fetch_registers): Unpack double regs to host double, then
3649 to extended.
3650 (nindy_store_registers): Pack extendeds to host double, flip
3651 around by misusing unpack_double, send as target double.
3652
3653 * tm-vxworks68.h (FRAME_CHAIN): Handle current frame pointer of
3654 zero, as when stopped at the first instruction of a process.
3655
3656 * blockframe.c: Fix filename in comment (param.h => tm.h).
3657 * sparc-tdep.c (skip_prologue): More explicit nudging comments.
3658 * tm-68k.h: Fix typos.
3659
3660 Fri Mar 15 01:09:34 1991 John Gilmore (gnu at cygint.cygnus.com)
3661
3662 Changes from a bringup on the DEC Vax under Ultrix 4.0.
3663
3664 * coredep.c (fetch_core_registers): Pass end-address of register
3665 section to register_addr as expected. Don't call supply_register
3666 if we'd just pass it garbage.
3667
3668 * dbxread.c (read_dbx_symtab): Skip N_NSYMS on Ultrix.
3669
3670 * exec.c (xfer_memory): Use boolean xfer_fn result, not int.
3671
3672 * target.c (push_target, target_info): Cast enums to int for < or
3673 > comparison.
3674
3675 * stack.c (print_frame_info): Identify source file & line
3676 even if we can't print it.
3677
3678 * xm-vax.h (MISSING_VPRINTF): No longer missing in Ultrix V4.0.
3679
3680 Sat Mar 9 10:08:20 1991 John Gilmore (gnu at cygint.cygnus.com)
3681
3682 Clean up IEEE floating point support.
3683
3684 * ieee-float.h: New file.
3685 * ieee-float.c: Write real routines to convert between host
3686 doubles and various target IEEE extendeds.
3687 * m68k-xdep.c: Eliminate assembler code for extended floats.
3688 * xconfig/{3b1,altos,altosgas,hp300bsd,isi,news,news1000,sun2os3,
3689 sun2os4,sun3,sun3os3,sun3os4}: Eliminate use of m68k-xdep.o.
3690 * tm-i960.h, tm-68k.h (REGISTER_CONVERT_TO_VIRTUAL,
3691 REGISTER_CONVERT_TO_RAW): Use ieee_extended_to_double and
3692 double_to_ieee_extended.
3693 * i960-tdep.c: Define ext_format_i960.
3694 * m68k-tdep.c: Define ext_format_68881.
3695 * sparc-tdep.c: Define ext_format_sparc, though unused.
3696 * Makefile.dist (HFILES): Add ieee-float.h.
3697 * inftarg.c: #include "ieee-float.h" for the REGISTER_CONVERT
3698 macros.
3699
3700 Obsolete the "coffstrip" program in favor of using BFD's strip.
3701
3702 * nindy-share/coffstrip.c: Remove file.
3703 * nindy-share/nindy.c (coffstrip): Routine to run bfd_strip.
3704 * Makefile.dist: Remove references to nindy-share/coffstrip.c.
3705 * tconfig/nindy960: Remove reference to coffstrip.o.
3706
3707 * Makefile.dist: Roll version number to 3.94.1 (not yet final).
3708
3709 Wed Mar 6 09:56:45 1991 John Gilmore (gnu at cygint.cygnus.com)
3710
3711 * symfile.h: Add symfile_bfd, common between dbxread and coffread.
3712 * dbxread.c: Remove static symfile_bfd.
3713 * infcmd.c (do_registers_info): Add PRINT_REGISTER_HOOK, though
3714 it is not used yet.
3715 * inftarg.c (child_detach): Pop the child_ops vector if the
3716 detach is successful.
3717 * remote-nindy.c (nindy_create_inferior): Don't push a new
3718 nindy_ops since nindy uses the same one for execution and memory
3719 examination anyway.
3720 * core.c (core_ops): Use child_attach and child_create_inferior
3721 rather than default attach and create_inferior functions.
3722
3723 Handle floating point registers in core files.
3724
3725 * sparc-xdep.c (fetch_core_registers): Rewrite for float support.
3726 * sun3-xdep.c (fetch_core_registers): Rewrite for float support.
3727 This version untested since BFD doesn't yet support sun3 core
3728 files.
3729 * hp300hpux-xdep.c: Rewrite fetch_core_registers to new calling
3730 conventions. Fix comments and style. This version has not
3731 been compiled yet, since we have no HP inhouse.
3732 * core.c (get_core_registers): Look for two sections, ".reg"
3733 and ".reg2", and pass both to fetch_core_registers sequentially.
3734
3735 Revise directory path yet again.
3736
3737 * source.c (forget_cached_source_info): Not static any more.
3738 (init_source_path): New default source path is "$cdir:$cwd".
3739 (dir_command): Handle variable arguments ($cdir, $cwd).
3740 (source_info): Print "Compilation directory" rather than
3741 "Originally compiled in" to remind people of $cdir.
3742 (openp): If the path contains $cwd, use current directory.
3743 (open_source_file): If compilation directory is known, replace
3744 first $cdir in path with the compilation directory.
3745 (print_source_lines): Even if we can't print the lines, set the
3746 current symtab and line for future commands like "info source" or
3747 "breakpoint". Also, error message now contains the file name,
3748 line number, and file access error message.
3749 (_initialize_source): Fix help text to describe changes.
3750 * main.c (cd_command): Forget cached source info when we chdir.
3751 * utils.c (strstr): Add simple implementation.
3752
3753 Tue Mar 5 01:41:40 1991 John Gilmore (gnu at fowanton.cygnus.com)
3754
3755 * coffread.c (read_one_sym, init_linetable, init_stringtab):
3756 Byte-swap COFF symbol tables if necessary when reading them in.
3757 Use complain() to replace error message in one spot. Needs
3758 corresponding change in bfd/coff-code.h to make some symbol
3759 swapping routines non-static.
3760
3761 Mon Mar 4 00:53:40 1991 John Gilmore (gnu at cygint.cygnus.com)
3762
3763 Merge changes from Eirik Fuller, for UTek.
3764
3765 * defs.h (errno): Add declaration.
3766 * altos-xdep.c, arm-xdep.c, convex-xdep.c, gould-xdep.c,
3767 hp300hpux-xdep.c, infrun.c, inflow.c, infptrace.c, i386-tdep.c,
3768 i386-xdep.c, pyr-xdep.c, mips-xdep.c, remote-eb.c, remote-nindy.c,
3769 remote-vx.c, source.c, standalone.c, stuff.c, sun386-xdep.c,
3770 symmetry-tdep.c, symmetry-xdep.c, umax-xdep.c, utils.c: Eliminate
3771 declarations of errno.
3772
3773 * remote-eb.c: Define B19200 and B38400 as EXTA and EXTB.
3774
3775 * remote-vx.c: Include <sys/time.h> for UTek; Sun gets it via
3776 <rpc/rpc.h> and <rpc/types.h>.
3777
3778 Sat Mar 2 15:47:55 1991 John Gilmore (gnu at cygint.cygnus.com)
3779
3780 * i960-tdep.c (examine_prologue): Add new argument limit,
3781 which stops the scan at the end of the prologue, or at the PC.
3782 This fixes a problem where it walks down into the code for the
3783 user's statements if that code looks like function prologues.
3784 Mark Fox and I have been bouncing this code back and forth, making
3785 small changes to it. Callers changed to match.
3786
3787 Tue Feb 26 01:47:07 1991 Cygnus John Gilmore (cygnus at yuba)
3788
3789 Cleanup for gdb-3.94 release final:
3790
3791 * Makefile.dist: Remove remote-vx.c, remote-nindy.c, and all
3792 the .c files from vx-share and nindy-share, from the various
3793 macros, since they are not found via ALLDEPFILES.
3794 (SFILES): Add tm-i960.h.
3795 (alldeps.mak rule): Break out ALLDEPFILES_MAINDIR and
3796 ALLDEPFILES_SUBDIR. List all the nindy and vxworks subdir files
3797 in the SUBDIR list.
3798 (TAGFILES_MAINDIR): Change ALLDEPFILES to ALLDEPFILES_MAINDIR.
3799 (gdb.tar.Z): Use ALLDEPFILES_SUBDIR as well as SFILES_SUBDIR.
3800
3801 Mon Feb 25 16:02:35 1991 Cygnus John Gilmore (cygnus at oldman)
3802
3803 * am29k-tdep.c: Add contribution line.
3804 (examine_prologue): Cache information about function prologues in
3805 the misc-function-vector to avoid lots of references over the
3806 serial line while examining instructions.
3807
3808 * core.c (core_close): New function made from cleanup_core.
3809
3810 * core.c, exec.c, inftarg.c, remote-eb.c, remote-nindy.c,
3811 remote-vx.c, remote.c, target.c, target.h,
3812 Update target_ops vector to add attach, close, and load entries.
3813 Use add_syms_addr_command, not add_file_addr_command, for
3814 add_file. Break out close routine from existing code.
3815
3816 * dbxread.c (really_free_pendings): Don't free pending_blocks;
3817 they are in an obstack.
3818 (read_dbx_symtab): Relocate end_of_text_addr in the psymtab.
3819 Lint.
3820 (define_symbol): Add symbol type parameter; change callers;
3821 pass type parameter to DBX_PARM_SYMBOL_CLASS macro to allow
3822 it to influence the symbol class on the i960.
3823 (define_symbol): Swap LOC_CONST's into target byte order.
3824
3825 * exec.c (exec_close): New function.
3826 (exec_file_command): Call it.
3827
3828 * findvar.c (read_relative_register_raw_bytes): Doc byte order,
3829 Fix byte order of frame pointer.
3830 (read_var_value): Result of 0 if var's value can't be found,
3831 e.g. missing FRAME_ARGS_ADDRESS. Byte-swap LOC_CONST and
3832 LOC_LABEL values to target order. Add LOC_LOCAL_ARG.
3833 (locate_var_value): Use read_var_value and use its lazy address
3834 as the location of the var's value. Lint.
3835
3836 * i960-pinsn.c (next_insn): Add routine from vxgdb for scanning
3837 instructions.
3838
3839 * i960-tdep.c (arg_address, i960_frame_find_saved_regs): Remove
3840 obsolete Intel versions in favor of vxgdb versions.
3841 (check_host, byteswap, byteswap_val, reorder_val): Eliminate
3842 code dealing with byte order of values, which Intel did in host byte
3843 order rather than gdb-4's target byte order.
3844 (i960_frame_chain_valid): Move to nindy-tdep.c.
3845 (examine_prologue, skip_prologue, frame_find_saved_regs,
3846 frame_args_address, leafproc_return, saved_pc_after_call,
3847 pop_frame): Add vxgdb versions from Mark Fox.
3848 (examine_prologue, frame_struct_result_address): Add code
3849 to deal with the saved value of G13 (struct return address
3850 pointer).
3851 (frame_args_address): Modify Mark's version to prefer the
3852 saved value over the current value in the topmost frame.
3853 Cache result in the frame info to avoid performance hair in
3854 callers.
3855 (print_fault): Add gdb960 code for printing faults.
3856 (_initialize_i960): Actually call check_host.
3857
3858 * ieee-float.c (ieee_extended_to_double, ieee_double_to_extended):
3859 add stub routines. FIXME, these currently just return zero!
3860
3861 * infcmd.c (program_info): Use PRINT_RANDOM_SIGNAL.
3862 (attach_command): Call target_attach, not target_open, now.
3863
3864 * infrun.c (normal_stop): Make global, not static, for vx_attach.
3865 (child_attach): Rename from child_open.
3866 (wait_for_inferior): Use PRINT_RANDOM_SIGNAL. If stop_pc is zero,
3867 don't confuse it with a zero step_resume_break_address.
3868
3869 * inftarg.c (child_detach): Eliminate inferior_pid test.
3870 (child_files_info): Clean up message a bit.
3871 (child_ops): Use child_attach, not child_open, to attach.
3872
3873 * mem-break.c: #ifdef out the whole file if BREAKPOINT is not
3874 set (e.g. on VxWorks or NINDY). Move read_memory_nobpt from
3875 findvar.c to here, since it depends on the contents of the
3876 shadow_contents of breakpoints, but keep if #if 0 since it is
3877 never called.
3878
3879 * nindy-tdep.c: New file, contains nindy_frame_chain_valid, moved
3880 from i960-tdep.c.
3881
3882 * printcmd.c (address_info): Handle LOC_LOCAL_ARG. Lint.
3883 (ptype_command, display_command): Eliminate have_inferior_p and
3884 have_core_file_p in favor of target_has_stack or
3885 target_has_execution.
3886 (print_frame_args): Handle LOC_LOCAL_ARG. Eliminate duplicate
3887 code for actually finding the values of arguments, though we still
3888 keep track of the maximum stack offset for use in printing unnamed
3889 arguments. Handle missing FRAME_ARGS_ADDRESS.
3890
3891 * remote-nindy.c (i960_print_fault): Move to i960-tdep.c.
3892 (struct nindy_regs): Define registers passed to/from nindy.
3893 (nindy_fetch_registers, nindy_store-registers): Translate between
3894 nindy and GDB formats for the registers.
3895 (dcache_init): Statically allocate the cache, since it was being
3896 allocated by a malloc that was never freed anyway.
3897 (nindy_create_inferior): Error, not core dump, if no exec file.
3898 (nindy_before_main_loop): Use target_load, not target_add_file.
3899
3900 * remote-vx.c (net_load): Specify large timeout for load
3901 requests. Allow user to break out with INTERRUPT.
3902 (net_break): Remove useless code, clean up. Change callers.
3903 (parse-args, skip_white_space, find_white_space): Clean up arg
3904 parsing to cope with quoted strings.
3905 (net_wait, net_quit): Never call error, just return status.
3906 (vx_read_register, vx_write_register): Cleanup status checking.
3907 #ifdef the code based on which CPU we are using (960 or 68k),
3908 FIXME, this should be completely general but it isn't yet.
3909 (vx_xfer_memory, vx_resume): Cleanup status checking.
3910 (vx_run_files_info): Improve message.
3911 (vx_load_command): Renamed from vx_add_file_command. Allow load
3912 to be interrupted.
3913 (net_ptrace): Remove unused routine.
3914 (vx_wait): Adopt code from vxgdb960 to cope with broken
3915 connections to target machine and prompt to disconnect. Remove
3916 debug printouts. Map some EVENT_'s to SIGnals.
3917 (add_symbol_stub, vx_open): Print names of object files we found,
3918 and "ok" if we read their symbols OK. Clarify output in general.
3919 (vx_attach, vx_detach, vx_kill): Add these commands.
3920 (vx_convert_from_virtual, vx_convert_to_virtual): Simplify.
3921 (vx_run_ops): Turn off all_mem, to avoid spurious msg in the
3922 "info files" output, and create_inferior, since we already have
3923 an inferior.
3924
3925 * stack.c (frame_info): Replace Frame_unknown with 0.
3926 (print_frame_arg_vars): Handle LOC_LOCAL_ARG.
3927 (return_command): Pop until the PC matches as well as the FP,
3928 so it works even if the FP is shared with another function,
3929 as in "frameless" or "leaf" procedures.
3930
3931 * symfile.c (load_command): renamed from add_file_target_command.
3932 (add_syms_addr_command): renamed from add_file_addr_command.
3933 (add_syms_command): Stub to call target_add_syms.
3934 (_initialize_symfile): Change command names and descriptions,
3935 add-file => add-syms, and load from alias to its own command.
3936
3937 * target.c (kill_or_be_killed, maybe_kill_then_attach,
3938 maybe_kill_then_create_inferior): Default for attempts to start
3939 a process, if one is already running, is to ask about killing
3940 it and retry if yes.
3941 (upstack_create_inferior): #if-0 it, strata obsolete it.
3942 (push_target, unpush_target, pop_target): to_close() a target
3943 before unstacking it.
3944 (target_info): Renamed from target_files_info.
3945 (_initialize_targets): Rename "i files" as "i target", accessible
3946 under both names.
3947
3948 * target.h: Improve comments about the target_ vectored routines.
3949
3950 * tm-i960.h: Remove NINDY-specific stuff to tm-nindy960.h.
3951 Convert commenting style to standard GNU style.
3952 (DBX_PARM_SYMBOL_CLASS): allow LOC_LOCAL_ARG's to be recognized.
3953 (SKIP_PROLOGUE): No longer a no-op.
3954 (SAVED_PC_AFTER_CALL): Now handles leaf procedures.
3955 (*_REGNUM): Sort register numbers.
3956 (REGISTER_BYTES, REGISTER_BYTE, REGISTER_RAW_SIZE,
3957 MAX_REGISTER_RAW_SIZE, REGISTER_CONVERTIBLE,
3958 REGISTER_CONVERT_TO_VIRTUAL, REGISTER_CONVERT_TO_RAW): Float regs
3959 are now 10 byte extendeds, not 8 byte doubles.
3960 (FRAME_CHAIN_VALID): Make this config-dependent, since it differs
3961 for nindy versus vxworks targets. FIXME, this should possibly go
3962 in the target vector.
3963 (EXTRA_FRAME_INFO, INIT_EXTRA_FRAME_INFO): Cache both
3964 frame_saved_regs and arg pointer with each frame.
3965 (FRAMELESS_FUNCTION_INVOCATION): New leafproc support.
3966 (FRAME_ARGS_ADDRESS): Use cached result.
3967 (FRAME_ARGS_ADDRESS_CORRECT): New, avoids g14 guessing.
3968 (FRAME_FIND_SAVED_REGS): Change arg to subsidiary fn.
3969 (PRINT_RAMDON_SIGNAL): Call print_fault.
3970 (POP_FRAME): Now works.
3971
3972 * tm-nindy960.h: Break this off tm-i960.h. NINDY-specific
3973 option parsing and startup; STACK_END_ADDR, FRAME_CHAIN_VALID,
3974 BREAKPOINT, and DECR_PC_AFTER_BREAK are here.
3975 (ADDITIONAL_OPTION_HANDLER): use target_load, not
3976 target_add_file.
3977
3978 * tm-vxworks960.h: Break this off tm-i960.h. VxGDB specific
3979 startup; DECR_PC_AFTER_BREAK, and FRAME_CHAIN_VALID are here.
3980
3981 * valarith.c (value_subscripted_rvalue): Avoid handling
3982 floats and doubles specially; it gave alignment errors. Lint.
3983
3984 * valops.c (value_of_variable, value_of_this): Error if unknown
3985 value.
3986
3987 * valprint.c (print_floating): Bcopy rather than pointer-deref,
3988 to avoid alignment problems.
3989 (value_print): Handle unknown value address.
3990 (cplus_val_print): Two args are ignored; remove them. Change caller.
3991 (val_print): Use unpack_long rather than pointer-deref.
3992
3993 * values.c: Lint.
3994 (unpack_long, unpack_double): Use bcopy rather than pointer-deref
3995 to avoid alignment problems.
3996 (value_being_returned): Error if return value unknown.
3997 (set_return_value): Add bogosity warning, FIXME. *
3998
3999 * TODO: A woman's work is never done.
4000
4001 * Makefile.dist: Distribute REMOTE_OBS into tconfig files.
4002 Separate INCLUDE_CFLAGS for use with lint. Add LINTFILES.
4003 Add ieee-float.o to OBS.
4004 * tconfig/{nindy960,vxworks68,vxworks960}: Include the desired
4005 REMOTE_OBS remote-interface files in the TDEPFILES and TM_FILE.
4006 * tconfig/i960: FIXME. Half-merge, produce warning if config'd.
4007
4008 Changes to generalize the VxWorks RPC protocol slightly, to handle
4009 i960 as well as 68000.
4010
4011 * vx-share/dbgRpcLib.h (VX_SOURCE_STEP): Add.
4012 * vx-share/reg.h: Produce i960 regs #ifdef I80960
4013 * vx-share/xdr_ptrace.c: Skip FPA registers if 960.
4014 * vx-share/xdr_rdb.h: Add SOURCE_STEP struct and xdr decl.
4015 * vx-share/xdr_rdb.c: Add xdr_SOURCE_STEP routine.
4016 * vx-share/xdr_regs.c: Add xdr_regs, xdr_fp_status, xdr_ext_fp
4017 for i960. Change xdr_vectors to xdr_opaques for 68k registers,
4018 so they will move in target byte order rather than network
4019 byte order (happens to be the same).
4020
4021 Mon Feb 25 03:41:44 1991 John Gilmore (gnu at cygint.cygnus.com)
4022
4023 * tm-convex.h (END_OF_TEXT_DEFAULT): Remove #if 0'd block.
4024
4025 Sun Feb 24 00:55:53 1991 John Gilmore (gnu at cygint.cygnus.com)
4026
4027 * am29k-pinsn.c,
4028 Add contribution lines to various files, showing where they
4029 came from.
4030
4031 * breakpoint.c (break_insn, check_break_insn_size,
4032 read_memory_nobpt): Remove to mem-break.c.
4033
4034 * xm-*.h, param-no-tm.h, tm-29k.h, valprint.c: Change BYTE_ORDER to
4035 HOST_BYTE_ORDER.
4036
4037 * tm-29k.h (STAB_REG_TO_REGNUM): Warn user if symbol table
4038 entry has bad register number. This change is not
4039 tested in this release, FIXME.
4040
4041 * frame.h: Eliminate Frame_unknown in favor of a simple zero.
4042 tm-vax.h: Ditto.
4043
4044 * value.h: Force value's contents field to be aligned to hold
4045 at least a double or a long long (if supported). This avoids
4046 doing bcopy's in and out of the contents field.
4047
4048 (step_1): Avoid coredump under obscure circumstances when we
4049 have no frame.
4050
4051 * symtab.h (misc_info): Add field to misc function vector for
4052 any kind of cached information the target code desires. AMD
4053 29000 uses this to avoid repeating examine_function_prologue's.
4054
4055 * coffread.c: Lint. Remove static symfile, read_section_header.
4056 core.c (have_core_file_p): Lint: remove.
4057 expprint.c (print_subexp): Lint.
4058 infptrace.c, valops.c, valprint.c: lint.
4059
4060 Roll in changes from vxgdb-5.0.1:
4061
4062 * symtab.h: Comment byte order of each address class. Add
4063 LOC_LOCAL_ARG for frame-relative args (960).
4064 expread.y: Use LOC_LOCAL_ARG where LOC_ARG is used.
4065 symtab.c, symmisc.c: ditto.
4066
4067 * infrun.c (init_wait_for_inferior): Clear stop_signal.
4068
4069 * remote.c (remote_resume): Error if resume with a signal.
4070
4071 * symfile.c (prim_record_misc_function): Clear misc_info.
4072 (fill_in_vptr_fieldno): Check stub type of arg.
4073
4074 * valops.c (value_cast): Avoid looking up names of types whose
4075 name we don't know, to prevent coredump. Sun CC produces typedef
4076 rtx and the name of *rtx is zero...
4077
4078 Mon Feb 18 21:16:25 1991 John Gilmore (gnu at cygint.cygnus.com)
4079
4080 Roll in changes from final AMD 29000 port (Tiemann).
4081
4082 tconfig/am29k: Add COFF_ENCAPSULATE and TARGET=TARGET_AM29K
4083 for ../include/a.out.encap.h. This might not work now that BFD
4084 is separately compiled. Instead, BFD support for encap will have
4085 to translate machine type 29k into the right COFF_MAGIC.
4086
4087 * infcmd.c: Remove references to inferior_pid that aren't used
4088 in actual ptrace calls; use target_has_execution, etc.
4089 (have_inferior_p): Remove function.
4090 (program_info): Print target info rather than "process number";
4091 avoid gratuitous messages unless from_tty.
4092 (run_stack_dummy, finish_command): Set proceed_to_finish.
4093 infrun.c: Remove inferior_pid refs. Decl & init proceed_to_finish.
4094 main.c: Lint. Lose have_inferior_p().
4095 inferior.h (have_inferior_p): Remove, lint.
4096 (proceed_to_finish): Add flag to ask that all regs be saved
4097 by normal_stop, for the few commands that need it, speeding up
4098 serial I/O. Add comments to stop_registers.
4099
4100 * remote-eb.c: Remove newline from breakpoint message we grep
4101 for. Never time out when running the user program.
4102
4103
4104
4105 Wed Feb 13 15:34:40 1991 John Gilmore (gnu at cygint.cygnus.com)
4106
4107 Roll in changes from vxgdb-5.0.1:
4108
4109 * dbxread.c (read_dbx_symtab): If we encounter a "FORTRAN COMMON"
4110 symbol in its raw form, we are processing an unlinked ".o" file.
4111 See if the target environment has assigned it an address, using
4112 target_lookup_symbol (VxWorks does), and enter it into the symtab
4113 that way.
4114
4115 * tm-vxworks.h (FRAME_CHAIN, FRAME_CHAIN_VALID): Override usual
4116 68k versions for a simpler version that assumes zero FP at bottom.
4117 Fixes bug of truncated stack reports.
4118
4119 * target.h (target_lookup_symbol): Define this routine's args
4120 and result, finally.
4121
4122 * target.c (nosymbol): Default routine for target_lookup_symbol.
4123 (target_default): Default lookup_symbol and call_function too.
4124 (files_info): Only print has_all_memory warning if a non-dummy
4125 target follows.
4126
4127 * remote-vx.c (vx_read_register, vx_convert_to_virtual,
4128 vx_convert_from_virtual): If target does not have floating point,
4129 zero register "values", and avoid doing cross-net conversions.
4130 (vx_lookup_symbol): Rename net_lookup_symbol, add to vectors.
4131 (vx_open): Rearrange code that attaches to target and reads
4132 symbols for all loaded modules, to work if some of the modules
4133 are not accessible. Add symbol_stub() and add_symbol_stub()
4134 as callbacks from catch_errors(). Allow connect attempt to be
4135 interrupted painlessly with ^C (FIXME, there are still some bugs
4136 if the interrupt happens during symbol reading.). Print
4137 final message with puts_filtered, since symbol messages are
4138 now filtered too.
4139
4140 Misc cleanup:
4141
4142 * main.c (catch_errors): Only print errstring if non-null.
4143 (command_loop): Avoid an ioctl per command to test ISATTY.
4144
4145 * remote-vx.c (net_load): make static; avoid sophomoric msg.
4146 (vx_xfer_memory): Return correct result!
4147 (vx_files_info): Indicate whether target has float or not.
4148 (vx_lookup_symbol): Complain, not error, if target gone.
4149 (vx_open): Print "Connected" msg before disabling immediate-quit.
4150 [FIXME: lookup_symbol and vx_open changes need testing.]
4151
4152 target.c, remote-eb.c, inftarg.c, am29k-opcode.h, target.h,
4153 tm-29k.h, tmm-vxworks68.h, symfile.c, gdb-int.texinfo: Add
4154 contributor lines and update copyrights to 1991.
4155
4156 Changes from an attempted H-PUX host port:
4157
4158 * infptrace.c (PT_ATTACH, PT_DETACH): Handle HP/UX, which
4159 defines PT_ATTACH and PT_DETACH but not PT_KILL.
4160 * remote-eb.c (eb_open): Misplaced endif kills sysv H/PUX.
4161 * remote-vx.c: include <sys/time.h> for HPUX.
4162 * hp300hpux-xdep.c (fetch_core_registers): Rewrite old
4163 "core_file_command" routine to BFD regime. May not work yet.
4164
4165 Attempted port of "gdb-3.4 Van Jacobson xgdb" to modern gdb.
4166
4167 * xgdb.c: Replace X10 version with some VJ version.
4168 (FIXME: Its copyright assignment is not on record.)
4169 * xgdb.c: Update include files to X11R4 (Xaw crud).
4170 (xgdb_display_source, create_text_widget): fix call to
4171 get_filename_and_charpos. Rewack source window stuff for X11R4
4172 (gleaned from include files, and "nm's" of binary libraries, since
4173 I had no doc available).
4174 (append_selection, append_selection_word): Disable with FIXME
4175 since R4 changed interface here.
4176 (create_buttons): Add back the old set of buttons.
4177 (xgdb_create_window): Fix call to XtInitialize (&argc not argc).
4178
4179 * Makefile.dist (xgdb, xgdb-init.c): Update for X11R4 on Suns.
4180 Roll VERSION to 3.94 (not yet final though).
4181
4182 Sat Feb 9 09:46:25 1991 John Gilmore (gnu at cygint.cygnus.com)
4183
4184 * obstack.h (obstack_ptr_grow, obstack_ptr_grow_fast,
4185 obstack_int_grow, obstack_int_grow_fast): Eliminate
4186 cast on left of assignment, which gives MIPS cc fits and is
4187 not Standard C.
4188
4189 * sparc-pinsn.c (print_insn): Eliminate 'set' test, subsumed by
4190 F_ALIAS. Use printf, not fprintf, when not passing a file
4191 pointer...
4192 (compare_opcodes): Check that identical instructions have
4193 identical opcodes, complain otherwise.
4194
4195 * sparc-opcode.h (st %fsr): Fix opcode "lose" mask. This
4196 was reported by Roland McGrath.
4197 (unimp): Only match if exactly zero instruction. (Roland)
4198 (branches and traps): Generate all variations of these
4199 instructions with macros, based on a single call that defines
4200 each condition name and its binary representation.
4201 (set): Turn on alias bit, to avoid test in sparc-pinsn.c.
4202
4203 * valprint.c (val_print_fields): Take, and use, format parameter.
4204 This means that "p/x struct" again prints the elements in the
4205 desired format. Changed callers.
4206
4207 * stack.c (frame_info): Use filtered output, and indicate wrap
4208 points. Remove kludgy formatting designed to avoid line wrap.
4209
4210 * utils.c (wrap_here): If the line is already full (because
4211 we had printed a long indent or long wrapped string), do an
4212 immediate newline-and-indent.
4213
4214 * m68k-pinsn.c (print_insn_arg): Bugfix from
4215 ntmtv!thompson@ames.arc.nasa.gov (Mike Thompson): 'bkpt #0'
4216 instruction is incorrectly disassembled as bkpt #8.
4217
4218 * dbxread.c (end_psymtab): Bugfix from Peter Schauer
4219 <pesrem@regent.e-technik.tu-muenchen.de>: If you want to set a
4220 breakpoint in a *.y file gdb will say Reading in symbols for *.y...
4221 and then will dump core (sometimes). I traced it back to an
4222 uninitialized symfile_name in psymtab_to_symtab.
4223 (const_vol_complaint): Add quotes to message.
4224 (define_symbol): Only believe line number if gcc_compiled.
4225 Avoid allocating symbol if we will not return it.
4226
4227 Add target strata support so that newly established targets go
4228 into their right place in the target stack (e.g. a new exec file
4229 doesn't wipe out the ability to access the running process).
4230
4231 * target.h, core.c, exec.c, inftarg.c, remote-eb.c,
4232 remote-nindy.c, remote-vx.c, remote.c, target.c: Add to_stratum
4233 and initialize it properly in all the targets.
4234
4235 * target.h: Document strata. Change return type of push_target.
4236
4237 * target.c (nomemory): new function for dummy memory access.
4238 (tcomplain): Rename complain, now also used in symfile.c.
4239 (push_target): Push targets within strata. New return value shows
4240 whether new target is on top of stack or not. Always keep dummy
4241 target on stack.
4242 (target_files_info): Ignore dummy target.
4243
4244 * core.c (core_open): Warn user, and skip accessing file, if the
4245 core target is not the topmost target in the stack.
4246 * remote-nindy.c (nindy_create_inferior): Avoid unpush_target, now
4247 already handled.
4248
4249 * remote-vx.c: Remove vx_prepare_to_store from vxworks memory
4250 target_ops, it doesn't belong there since we have no regs there.
4251 Change name of target from machine => memory to clarify.
4252
4253 Thu Feb 7 16:32:09 1991 John Gilmore (gnu at spiff.cygnus.com)
4254
4255 * Freeze version 3.93 for release.
4256
4257 * Makefile.dist: Handle vx-share and nindy-share subdirs
4258 properly when building gdb.tar.Z.
4259
4260 * symtab.c: lint; add no_symtab_msg to consolidate the messages
4261 printed in various places, so I could change just one copy.
4262
4263 * dbxread.c, coffread.c: Change references to bfd->iostream
4264 to cast to FILE *, now that BFD avoids needing types defined
4265 in other header files.
4266
4267 Tue Feb 5 21:39:35 1991 John Gilmore (gnu at cygint.cygnus.com)
4268
4269 * command.c, dbxread.c, expprint.c, infcmd.c, infptrace.c,
4270 infrun.c, printcmd.c, remote-nindy.c, source.c, sparc-tdep.c,
4271 sparc-xdep.c, symfile.h, symmisc.c, utils.c, valprint.c: Lint
4272 (actually gcc -Wall).
4273
4274 * dbxread.c: Remove first_global_sym, last_global_sym, since
4275 they are never referenced.
4276
4277 * defs.h (baud_rate): Declare.
4278 main.c: Define it, and add the -b option to set it.
4279
4280 * gdb-int.texinfo: Add text on how to define a new host or target
4281 architecture, prompted by Per Bothner's questions about MIPS
4282 support.
4283
4284 * gdb.texinfo: Document "complaints". Change doc of -q since
4285 gdb no longer prints the copyright and blurb if you specify a file
4286 name to be debugged (just like Emacs). Add doc for Nindy-specific
4287 command line flags for specifying target serial port and such.
4288 Update copyright to 1991.
4289
4290 * gdbcore.h: Remove a large mass of now-useless crud, since BFD
4291 has taken over for us the job of ripping up executable files. The
4292 crud caused Per Bothner's port to not compile.
4293
4294 * infrun.c (normal_stop): Avoid printing "Program exited
4295 normally" if we are in batch mode. This allows a GDB which
4296 executes a program on a target system, to behave like a Unix
4297 command (input from stdin, output to stdout, no extraneous
4298 output).
4299
4300 * main.c (main): Allow additional machine-dependent command line
4301 options to be specified with the ADDITIONAL_OPTIONS,
4302 ADDITIONAL_OPTION_CASES, ADDITIONAL_OPTION_HELP, and
4303 ADDITIONAL_OPTION_HANDLER macros. Also allow machine-dependent
4304 processing to occur just before the main loop with
4305 BEFORE_MAIN_LOOP_HOOK.
4306 (main): If a "core file" argument is specified, and it is not a
4307 core file, try it as a process ID to attach.
4308 (symbol_completion_function): Attempt to cope with
4309 "show screen-" TAB, not very successfully. This needs more work,
4310 FIXME.
4311 (batch_file): New function, returns whether we are reading
4312 commands from an interactive tty on stdin, or from somewhere else.
4313 Called by normal_stop since it doesn't get from_tty passed down
4314 to it like many commands do.
4315
4316 * remote-nindy.c: Handle command line options for nindy
4317 connection.
4318 (nindy_before_main_loop): Prompt user for tty name if they
4319 don't specify it before getting to the interactive command loop.
4320
4321 * tm-i960.c: Add ADDITIONAL_OPTIONS, etc, to handle -O, -brk,
4322 and -r command line options. Also add hook before main loop
4323 to make it easy to specify a tty.
4324
4325 * TODO: More things to do, one done.
4326
4327 Mon Feb 4 23:57:39 1991 John Gilmore and Mike Tiemann (at cygint.cygnus.com)
4328
4329 * dbxread.c: Make complaint() calls pass pointer, not struct.
4330 Add complaints about badly formatted C++ type information
4331 (const/volatile indicator, and parse errors resulting in
4332 error_type). Fix C++ virtual member fn comment.
4333 (read_struct_type): Avoid bumping pointer if we got a parse
4334 error; this prevents our walking beyond the end of a string.
4335 Terminate loop on null char as well as semicolon.
4336 (process_one_symbol): Fix the LBRAC fix so that it uses the
4337 last previous SLINE, FUN, or SO record's PC address. C++ debug
4338 symbols did not have SLINE records in a useful order compared
4339 to the LBRAC records.
4340 (define_symbol): Handle "catch" records.
4341
4342 * symtab.c (check_stub_type): Added new complain
4343 `stub_noname_complain' and added a consistency check to
4344 keep the debugger from crashing when finishing from an
4345 exception frame. A real fix will be needed later.
4346
4347 Sat Feb 2 10:43:05 1991 John Gilmore (gnu at cygint.cygnus.com)
4348
4349 * infcmd.c (attach_command): Make global.
4350
4351 * Makefile.dist (REMOTE_OBS): Make these compile by default,
4352 but make them easy to comment out. Perhaps later they should
4353 be enabled by what CPU you configure for? FIXME.
4354 (VERSION): Roll to 3.93.
4355 (pinsn.o): Remove rule for obsolete file.
4356 (dbxread.o,coffread.o,mipsread.o): Use ${srcdir} explicitly.
4357
4358 Run down a problem that manifested by printing the wrong function
4359 name in stack traces of read_ofile_symtab. Turned out that the
4360 problem was the SunOS 4.1.1 (and previous) C compiler outputs
4361 the LBRAC symbol with an address in the *data* segment, which
4362 blew our binary search through the blocks.
4363
4364 * dbxread.c: Use the complain() facility consistently to bitch
4365 about problems in the symbol file we are reading.
4366 (finish_block): Add code to check the nesting of the blocks;
4367 complain and Procrust them to fit if wrong.
4368 (make_blockvector): Check the order of the blocks, complain
4369 [but don't cope] if wrong.
4370 (process_one_symbol): ifndef SUN_FIXED_LBRAC_BUG, check LBRAC
4371 symbols to be sure their PC value is greater than the last SLINE
4372 (line number) symbol we've seen, complaining and adopting the
4373 SLINE PC value if wrong.
4374
4375 * symfile.h (struct complaint, complaint_root, complain,
4376 clear_complaints): Add.
4377 * symfile.c (complain, complaint_root, clear_complaints): Add
4378 facility to deal with non-fatal complaints and to regularize their
4379 suppression.
4380 (symbol_file_add): Clear complaint counters to allow new complaints.
4381 (initialize_symfile): Add 'set complaints' and 'show complaints'.
4382
4383 * dbxread.c (dbx_symfile_read): Remember the address and size
4384 of the string table for the main symbol file, so we won't read it
4385 more than once.
4386 (dbx_psymtab_to_symtab): Fix the check for main symbol file,
4387 to avoid reading the string table yet again. Lint.
4388 (throughout): Improve filtered output, including word wrap.
4389 (read_range_type): Improve Bothner's fix to handle other types too.
4390
4391 * utils.c: Improve line wrap implementation. Handle unlimited
4392 width by making chars_per_line unsigned.
4393 (puts_filtered): New, easy, function.
4394
4395 * defs.h (puts_filtered): add.
4396
4397 * mipsread.c (compare_symbols, sort_symtab): Remove these fns,
4398 call the identical sort_symtab_syms() in symfile.c instead.
4399
4400 * expread.y: Suggest the `file' command rather than `symbol-file'.
4401
4402 * command.h (enum var_types): Add zinteger for seroable
4403 unsigned integer.
4404 * command.c (do_setshow_command): Handle var_zinteger. Restructure
4405 nested if's into a switch.
4406
4407 * breakpoint.c (bpstat_print): If bpstat "print" flag is not set,
4408 we did not stop because of a breakpoint (it must have been for
4409 some other reason, like a "stepi"), so don't print anything.
4410
4411 * symtab.c: Include <sys/types.h> all the time. Now that BFD
4412 doesn't include <sys/types.h>, old SunOS's require it for
4413 <sys/stat.h>.
4414
4415 Sat Feb 2 10:39:15 1991 Per Bothner (bothner@cs.wisc.edu)
4416
4417 A test port of gdb-3.92.6 to the Sony NEWS.
4418
4419 * Makefile.dist
4420 Don't normally link in remote- or vx stuff.
4421 Some of it doesn't compile, and it wastes space for 99% of the users.
4422 Remove reference to no-longer-used HAVE_VPRINTF.
4423 Fixed BFD_DEP typo to BFD_DIR.
4424 * dbxread.c
4425 Fix cast in arg to bfd_h_getlong.
4426 Make char *prefix be const.
4427 Fix how certain range types are mapped into builtin unsigned int types.
4428 * infrun.c
4429 Remove 2 #includes. They cause errors (on Sony, at least),
4430 and aren't needed (they wern't in earlier versions).
4431 * printcmd.c
4432 print_address_symbolic should never demangle labels
4433 (since it prints *assembler-level* labels).
4434
4435 [This was superseded by the change to printcmd below.]
4436
4437 * utils.c
4438 Add some "volatile" return types to avoid warnings.
4439 If MISSING_VPRINTF add vprintf function and not just macro
4440 (since vprintf is used in printcmd.c).
4441 * valprint.c
4442 Unless __GNUC__, use obstack_grow instead of obstack_ptr_grow.
4443 (The latter isn't grokked by some PCC-based compilers.)
4444
4445 [This change is in abeyance, we prefer to fix obstack_ptr_grow.]
4446
4447 Make chunk size of dont_print_obstack 32*4 instead of default 4096.
4448 * nindy-share/coffstrip.c
4449 Added some forward declarations (otherwise, gcc complains
4450 about implicit extern redefined as static).
4451
4452 Sun Jan 20 02:38:19 1991 John Gilmore (gnu at cygint.cygnus.com)
4453
4454 Changes inspired by Per Bothner:
4455 * printcmd.c (print_address_symbolic): Take additional parameter
4456 specifying whether to demangle.
4457 (print_address): Pass in asm_demangle to control demangling.
4458 (print_address_demangle): New fn, takes explicit arg to control
4459 demangling.
4460 * utils.c: Add new vars demangle and asm_demangle, and let them
4461 be set and shown.
4462 (fputs_demangled): If !demangle, just print the argument.
4463 (fprint_symbol): If !demangle, just print raw symbol.
4464 * valprint.c (val_print): Call print_address_demangle rather than
4465 print_address, to cause demangling to depend on the global
4466 rather than assembler-level demangling setting.
4467 * WHATS.NEW, gdb.texinfo: Document.
4468
4469 * main.c (show_command): Show all settings if no arg.
4470 (initialize_main): Make "info set" the same as naked "show".
4471 * command.c (cmd_show_list): Handle prefix commands in the
4472 list, and print the name of the setting as well as its English
4473 description and value.
4474
4475 Allow gdb functions to specify where a line should wrap if it
4476 exceeds the size of a terminal line. Use it to make the output
4477 prettier.
4478 * utils.c (set_screen_width_command): New fn, mallocs a buffer
4479 of the right size when screen width changes.
4480 (set_screensize_command, screensize_info): Remove #if 0'd fns.
4481 (wrap_here): New fn, indicates a point in the output where we
4482 should wrap the line rather than just letting it overflow at a
4483 random place.
4484 (fputs_filtered): Implement wrapping.
4485 (n_spaces): New fn, returns a pointer to N spaces.
4486 (print_spaces_filtered): Use n_spaces.
4487 * defs.h (n_spaces): Declare.
4488 * stack.c (print_frame_info): Wrap with 4-space indent after
4489 fn name and before filename and line number.
4490 * printcmd.c (print_frame_args): Wrap with 4-space indent
4491 before each argument name is printed.
4492 * valprint.c (value_print): Wrap with no indentation before
4493 each repetition.
4494 (val_print_fields): Wrap with indentation relative to nesting
4495 level before each field name.
4496 (val_print): Wrap with nesting indentation before array elements.
4497 * command.c (do_setshow_command): Avoid extra newlines,
4498 wrap with 4-space indent around values printed, end with period.
4499 * WHATS.NEW, gdb.texinfo, gdb-int.texinfo: Document.
4500
4501 * breakpoint.c (breakpoint_1): Implement addressprint for
4502 "info breakpoints" display. Change file name and line number
4503 format to " at file:nnn" rather than " (file line nnn)".
4504 * gdb.texinfo: Document.
4505
4506
4507 Fri Jan 18 07:21:25 1991 John Gilmore (gnu at cygint.cygnus.com)
4508
4509 Frozen for gdb-3.92.6 release.
4510
4511 README, WHATS.NEW: Update for 3.92.6 release.
4512
4513 tconfig/{altos, i386v, i386v32, m88k, umax}: Eliminate
4514 coffread.o from configs since it is now built by default.
4515 tconfig/{3b1, altosgas, arm, convex, hp300bsd, hp300hpux,
4516 i386v-g, i386v32-g, isi, merlin, news, news1000, np1, pn,
4517 pyramid, symmetry, vax, vxworks68}: Eliminate dbxread.o
4518 from configs since it is now built by default.
4519
4520 Makefile.dist: Update for release 3.92.6. Handle files that
4521 have been moved to ../include, ../getopt, or ../bfd. Add
4522 saber.suppress and tests directory. Add config.status to
4523 the release (it will say "none").
4524
4525 coredep.c: Minor formatting fixes.
4526
4527 These changes were made in early December but only checked in now:
4528 * nindy-share/Onindy.c, nindy-share/coffstrip.c,
4529 nindy-share/nindy.c: lint
4530 * nindy-share/nindy.c (ninStopWhy): Don't byteswap the
4531 register values coming back from the target; we store values
4532 in target byte order everywhere.
4533
4534 Wed Jan 16 19:01:37 1991 John Gilmore (gnu at cygint.cygnus.com)
4535
4536 * am29k-opcode.h, am29k-pinsn.c: Add 29050 opcodes.
4537
4538 * valprint.c (cplus_val_print, val_print_fields): New functions,
4539 which print C++ objects. They conspire to avoid printing a
4540 virtual base class more than once, following all the twists and
4541 turns of C++ virtual base rules.
4542 (val_print): Call the above rather than do it by hand.
4543
4544 * symfile.c (symbol_file_add): Only reset symfile_mtime for main
4545 symbol file, not for added files like shared libs. This really
4546 needs to be generalized to a timestamp per file.
4547
4548 * core.c (cleanup_core): Avoid coredump if no core file.
4549
4550 * config.gdb: Accept -host or -target in place of +host or
4551 +target.
4552
4553 * coffread.c (find_linenos): Avoid desupported BFD interface
4554 to line numbers. We still read them manually rather than using
4555 BFD's "generic" features.
4556
4557 * gdbrc.tex, threecol.tex: Add GDB reference card and its
4558 formatting code.
4559 Makefile.dist: Add refcard to OTHERS list for creating tar files.
4560
4561 * Makefile.dist: Eliminate use of $< in explicit targets.
4562
4563 * readline/Makefile: Use $< rather than $*.c, which does not
4564 include the VPATH in GNU Make.
4565
4566 * tconfig/i960-bout, tconfig/i960-coff: These are identical
4567 copies of tconfig/i960, added for global configuration
4568 compatability. All i960 versions can read both coff and b.out.
4569
4570 * tm-88k.h: Fix multiline macro that lacked \'s. Remove
4571 COFF_FORMAT and COFF_CHECK_X_ZEROES since these are now handled
4572 automaticaly.
4573
4574 * TODO: Think of more things to do.
4575
4576 Wed Jan 2 19:09:29 1991 John Gilmore (gnu at spiff.cygnus.com)
4577
4578 tconfig/{am29k,i960,sun2*,sun3*,sun4*}: Eliminate config
4579 of sdb versus dbx debug symbols. Add kludge for 68881 80-bit to
4580 64-bit float conversion.
4581
4582 tconfig/sun4, tconfig/sun3, xconfig/sun4, xconfig/sun3: Make
4583 equivalent to sun?os4 so global config works.
4584
4585 Wed Jan 2 18:20:51 1991 John Gilmore (gnu at spiff.cygnus.com)
4586
4587 Fix from Eberhard Mattes <mattes@azu.informatik.uni-stuttgart.de>
4588
4589 * main.c: Only declare linesize once; declare pagesize not at
4590 all, since it is never used.
4591 (main): Clear newly allocated line before it is used.
4592
4593 Fri Dec 28 00:13:42 1990 John Gilmore (gnu at cygint)
4594
4595 Further stabilization for the Intel 960.
4596
4597 * Makefile.dist: Parameterize the location of the "include"
4598 and "bfd" directories, as well as "getopt". Add symfile.c.
4599 Link in both dbxread and coffread. Fix up "make depend" to
4600 rewack the locations of include, bfd, and getopt in its output.
4601
4602 * README: Document moving include files, improve some of
4603 the other doc.
4604
4605 * coffread.c: Move common code out to symfile.c. Change
4606 symbol_file_command style interface to use new *_symfile_init
4607 and *_symfile_read interface under BFD. Use BFD internal
4608 info to locate line table, symbols, etc.
4609
4610 * core.c (core_fetch_registers): Rename to get_core_registers
4611 to avoid confusion with fetch_core_registers.
4612 (register_addr): Move to coredep.c, which is already machine
4613 dependent. This leaves core.c pretty clean of dependencies.
4614
4615 * coredep.c (register_addr): Accept this routine from core.c.
4616
4617 * dbxread.c: Move common code (with coffread.c, etc) into new
4618 symfile.c. Each psymtab now contains a pointer to the
4619 format-dependent function that knows how to read it in. Make
4620 some things static.
4621 (dbx_psymtab_to_symtab): Renamed from psymtab_to_symtab_2.
4622 (process_one_symbol): Add code to complain about a "compiler bug
4623 we muzzle here", if we actually see it.
4624
4625 * eval.c (evaluate_subexp): Insert missing "break" statements
4626 in code that determines whether a variable is an lvalue in
4627 memory, register, or whatever. I detected this via a compiler
4628 bug in which it *almost* mashed out the whole switch statement.
4629
4630 * gdb-int.texinfo: Add minor sections on configuring gdb for
4631 release, and about the README file.
4632
4633 * infcmd.c (registers_info): Fix formatting somewhat. Still
4634 not as pretty as before, but it handles byte swapping.
4635
4636 * remote-nindy.c: If data cache routines are interrupted while
4637 waiting for the remote end, be sure that any uninitialized cache
4638 blocks are on the free list, not on the valid list!
4639
4640 * symfile.h: Flesh out this header file with all the various
4641 routines and variables that have been merged in from dbxread.c
4642 coffread.c, and symtab.c to symfile.c.
4643
4644 * symfile.c: New file, containing code common to dbxread.c,
4645 coffread.c, and some code from symtab.c. All generic code for
4646 reading symbol files should be in here now.
4647 (unrecord_misc_function): Remove unused function.
4648
4649 * symtab.h: Remove file-reading things to symfile.h.
4650
4651 * symtab.c: Remove file-reading things to symfile.c.
4652
4653 * tm-i960.h: Fix FRAME_CHAIN types; define PRINT_RANDOM_SIGNAL
4654 to decode i960 fault types.
4655
4656 * target.h, remote.c, remote-eb.c, remote-vx.c, remote-nindy.c,
4657 target.c: Change type of the "resume" function from int to void,
4658 since its result was never used.
4659
4660 Sat Dec 22 02:51:40 1990 John Gilmore (gnu at cygint)
4661
4662 * main.c: Replace "stupid" with "caution"; you now "set caution
4663 on or off".
4664
4665 * printcmd.c (print_scalar_formatted): Fix typo in 'g' format
4666
4667 * infcmd.c (do_registers_info): Call val_print to deal with the
4668 byte order of the registers being printed. FIXME, this makes
4669 the formatting of the output uglier.
4670
4671 * infcmd.c (wait_for_inferior): If PRINT_RANDOM_SIGNAL is
4672 defined, call it for signals the debugger doesn't itself use.
4673 The i960 uses this for more detailed fault information.
4674
4675 * remote.c (remote_open): If arg is null, print help rather than
4676 dumping core.
4677
4678 * sparc-xdep.c (register_valid): Avoid declaring size, since
4679 various modules will think of various sizes depending on the
4680 architecture of their tm-file. FIXME, we need protection against
4681 actually entering one of those modules, which would clobber
4682 storage if not for the target architecture compiled into gdb.
4683
4684 * stack.c (up_command, down_command): Always print the frame
4685 you arrive at.
4686 (up_silently_command, down_silently_command): New commands
4687 for use in scripts.
4688
4689 * i960-pinsn.c (reg), i960-tdep.c: Lint.
4690
4691 * i960-tdep.c (i960_frame_chain_valid): Lookup_symbol now takes
4692 more parameters than it used to.
4693
4694 * findvar.c (registers): Increase slop to 256 bytes, which should
4695 protect us against even most RISC machines with large register
4696 sets.
4697 (locate_var_value): Move declaration inside related ifdef.
4698
4699 * remote-nindy.c (): Use TIOCSETN rather than TIOCSETP
4700 throughout, to avoid throwing away buffered input from the board.
4701 (nindy_wait): Supply_register takes addr_of_value, not value.
4702 (i960_print_fault): Renamed from i80960_fault.
4703 (nindy_fetch_registers): Avoid have_regs stuff, just get them.
4704 (nindy_store_registers): Avoid regs_changed stuff, just stuff
4705 them.
4706 (nindy_create_inferior): Don't bother to write PC_REGNUM since
4707 we can set the PC in the call to proceed(). Unpush nindy_ops
4708 before pushing it on top, to avoid message to user. Eliminate
4709 commentary from Unix machines that just misleads here.
4710 (reset_command): Fix error message to suggest target command.
4711
4712 Wed Dec 19 11:03:56 1990 John Gilmore (gnu at cygint)
4713
4714 Release 3.92.5 as frozen.
4715
4716 Stabilize the merged release...with help from lint, Saber C,
4717 gcc -W, etc.
4718
4719 Everywhere: Add include files needed to declare return types
4720 of functions called.
4721
4722 * gdb.texinfo: Roland Pesch is documenting gdb, glory be!
4723
4724 * breakpoint.h: Add undeclared breakpoint functions, and some
4725 functions for display handling since I couldn't think of a better
4726 .h to put them in.
4727
4728 * breakpoint.c (insert_breakpoints): Make code for disabling
4729 shared library bkpts more likely to work. It's used when we
4730 rerun a program and stop before the shared library has been
4731 mapped in.
4732 (breakpoint_cond_eval, bpstat_stop_status): Pass arg as int,
4733 cast from pointer, so it squeezes through catch_errors.
4734 (bpstat_stop_status): Fix logic broken some time ago. We now
4735 always create a bpstat if the stop address matches a breakpoint,
4736 even if we don't stop there -- just like the old code used to do
4737 before I got my fingers into it (sigh).
4738 (breakpoint_1): Print "ignore count" after "stop only if"
4739 condition, since that's how it actually works.
4740 (mention): Handle watchpoints as well as breakpoints.
4741 (watch_command): use set_raw_breakpoint and mention to do most
4742 of the work (and initialize all the fields!). Only pass one
4743 arg to parse_c_expression, since that's all it takes.
4744
4745 * command.c (not_just_help_class_command): Rename arg to args
4746 since we ignore "unused argument" warnings on vars named "args".
4747 inflow.c (child_terminal_info): ditto.
4748 infptrace.c (kill_inferior): ditto
4749 main.c (catch_errors, version_info, quit_command, pwd_command,
4750 source_command, dump_me_command, editing_info,
4751 set_history_size_command, set_history, show_history,
4752 set_verbose): ditto
4753 stack.c (locals_info): ditto
4754 target.c (target_files_info): ditto
4755 valprint.c (set_input_radix, set_output_radix): ditto
4756
4757 * core.c: Remove old variables for handling core and exec file
4758 sections (data_start, data_end, stack_start, stack_end,
4759 reg_stack_start, reg_stack_end, reg_stack_offset, text_start,
4760 text_end, exec_data_start, exec_data_end, text_offset,
4761 exec_data_offset, data_offset, stack_offset). They're
4762 superseded the more general build_section_table and
4763 xfer_memory.
4764 (get_exec_file): Mention the `file' command.
4765 (read_memory_check): Rename to memory_error, and only call it
4766 in the case of an actual error.
4767 (read_memory, write_memory): call memory_error.
4768 (core_fetch_registers): Register section name is ".reg".
4769
4770 coredep.c: Remove a bunch of crud now that all this file does
4771 is pull the registers out of a core file.
4772 (fetch_core_registers): Rewrite to actually work, I hope.
4773
4774 dbxread.c: Use a.out.gnu.h, not system a.out, now.
4775 Replace index() with strchr(). Remove all the pre-BFD macro
4776 definitions for accessing the symbol file.
4777 (struct dbx_symfile_info): Encapsulate the information that
4778 dbx_symfile_init needs to pass to dbx_symfile_read in this
4779 struct.
4780
4781 (dbx_new_init, dbx_symfile_init, dbx_symfile_read,
4782 dbx_symfile_discard): Rearrange symbol file reading to divide
4783 the format-specific part from the format-independent part,
4784 leaving the format-independent part such as file name expansion
4785 and opening in symtab.c. This replaces
4786 partial_symbol_file_open and partial_symbol_file_read.
4787 Symbol_file_read, add_file, add_file_target_command,
4788 add_file_addr_command move to symtab.c. Pass an explicit
4789 "mainline" flag for when reading the main symbol table, rather
4790 than relying on the offset address to be zero or nonzero.
4791
4792 (dbx_symfile_read): Don't allow void *'s to be printed as
4793 typedefs.
4794 (SWAP_SYMBOL): Use bfd routines to byte-swap the symbols.
4795 (ADD_PSYMBOL_TO_LIST): Make the "function call rather than
4796 macro" debug version really work.
4797 (read_dbx_symtab): Remove unref'd parameter inclink.
4798 Avoid swapping N_SLINE symbols, for speed.
4799 Merge N_TEXT!N_EXT case with the other external symbol
4800 definitions' case. Add comments.
4801 (start_psymtab): Allocate the symfile name in the psymtab on
4802 the psymbol_obstack, rather than using the caller's storage.
4803 (end_psymtab): Only allocate a dependencies list if there are
4804 more than zero.
4805 (psymtab_to_symtab_2): Use BFD when reopening file to read
4806 its symbols for real.
4807 (read_struct_type): Add FIXME comments where it needs work
4808 for C++ bogosity.
4809 (read_huge_number): Add FIXME about overflows.
4810 (read_range_type): Add FIXME about comparing a long to 1<<32.
4811
4812 * coffread.c: Minor changes to move things closer to the new
4813 regime with symtab.c and dbxread.c Major work is still needed
4814 here.
4815
4816 * exec.c (exec_file_command): Remove old variables (see core.c
4817 above).
4818 (xfer_memory): If memory transfer is right at the end of a
4819 section, don't lose.
4820
4821 * findvar.c (get_saved_register): If value is in a real
4822 register, LVAL is lval_register, not lval_memory.
4823
4824 frame.h: Declare print_sel_frame and record_selected_frame.
4825
4826 gdb-int.texinfo: New file, for GDB internals documentation.
4827 Very simple, unformatted doc of cleanups is there for now.
4828
4829 gdbcore.h: Remove obsolete variables that described a.out
4830 section addresses and offsets. (See core.c above.)
4831 Declare fetch_core_registers and registers_fetched.
4832
4833 getopt.c: Declare char *alloca(); even on SPARC.
4834
4835 infcmd.c (run_command): Call target_kill rather than
4836 kill_inferior.
4837 (step_command, next_command, stepi_command, nexti_command):
4838 Declare from_tty parameter even though we don't use it.
4839 (run_stack_dummy): argument BUFFER is a char array, not
4840 a pointer to REGISTER_TYPE.
4841 (finish_command): using_struct_return needed a value *,
4842 not a struct symbol *.
4843
4844 * infptrace.c (child_xfer_memory): To avoid dependency on
4845 where sections are in memory, try PT_WRITE_D and if that fails,
4846 try PT_WRITE_I. Most Unixes don't care which you use.
4847
4848 * infrun.c (step_resume_break_shadow): Change to array to
4849 match other breakpoint shadow storage.
4850 (clear_proceed_status): Pass address of bpstat to
4851 bpstat_clear, not the bpstat itself.
4852 (child_create_inferior): FIXME comment about if the child
4853 exits.
4854 (start_inferior): Remove old function.
4855 (child_open): Use target_kill rather than kill_inferior.
4856 (wait_for_inferior): Ditto.
4857 (insert_step_breakpoint, remote_step_breakpoint): Use
4858 new step_resume_break_shadow.
4859
4860 * inftarg.c (child_wait): If all child processes die,
4861 pretend that the one being waited for exited with signal 42.
4862
4863 * main.c (command_line_input): When scanning for comments,
4864 don't coredump on unclosed quotes.
4865 (quit_command): Use target_kill rther than kill_inferior.
4866 (_initialize_main): Rename class_user from "user" to
4867 "user-defined".
4868
4869 * printcmd.c (print_command_1): Initialize "fmt" if no format
4870 is specified by the user.
4871 (print_frame_args): Only add to args_printed if we are
4872 actually fetching args from the stack (avoiding undefined
4873 arg_size).
4874 (_initialize_printcmd): Remove bogus \{ from string.
4875
4876 * remote-eb.c (eb_open): Avoid coredump on no argument.
4877
4878 * remote-nindy.c: Bring out of Intel environment into new
4879 target environment. Remove all conditional compilation on
4880 I80960. Massive hacking throughout.
4881 (nindy_xfer_inferior_memory): New routine stolen from
4882 infptrace.c.
4883 (nindy_create_inferior): New routine pieced together, probably
4884 not quite working yet.
4885 (nindy_ops): New target_ops struct for nindy.
4886
4887 * remote-vx.c: Use write_memory rather than target_write_memory
4888 to get error checking.
4889 (vx_add_file_command, vx_open): Use symbol_file_add rather than
4890 add_file.
4891 (vx_create_inferior): Use target_terminal_ours...
4892
4893 * signame.c (_initialize_signame): Always initialize, since
4894 we need the table for things other than psignal.
4895
4896 * solib.c (solib_add): Use symbol_file_add, not add_file.
4897 (solib_address): Return boolean result rather than struct
4898 pointer which nobody else knows the type of.
4899
4900 * sparc-tdep.c, valops.c: Use write_memory rather than
4901 target_write_memory, to get error checking.
4902
4903 * stack.c (locals_info, catch_info, args_info,
4904 get_selected_block, frame_command, up_command): Use
4905 target_has_stack, rather than have_inferior_p or
4906 have_core_file_p.
4907
4908 * sun3-xdep.c (fetch_core_registers): Rewrite for new BFD regime.
4909
4910 * symfile.h: New file, defining the interface between the
4911 generic and object-file-specific symbol reading code.
4912
4913 * symtab.c: Move generic symbol-reading interface to symtab.c,
4914 from dbxread.c, coffread.c, mipsread.c, etc. Add symtab_fns
4915 table to map BFD targets to symbol-reading modules in GDB.
4916 Change index to strchr.
4917 (lookup_struct_elt_type): Use error() rather than hand-made
4918 simulations thereof.
4919 (lookup_partial_symbol): Speedup slightly when length == 0.
4920 (symbol_file_add): New function.
4921 (symbol_file_command): Call it.
4922 (symfile_open, symfile_init): New function.
4923 (add_file_target_command, add_file_addr_command): moved from
4924 dbxread.c.
4925
4926 * target.c (target_command): use target_kill.
4927
4928 * target.h (target_files_info): Don't declare, never called
4929 from outside.
4930
4931 * tm-sun2.h, tm-sun3.h (STACK_END_ADDR): Use system include
4932 files to determine stack end address.
4933
4934 * valarith.c (value_x_binop, value_x_unop): Change error message
4935 to be more useful. Pass proper argument to value_struct_elt.
4936
4937 * valops.c (value_assign): FIXME comment that long long
4938 bitfields will break here.
4939
4940 * Makefile.dist: Add symfile.h, remote-nindy.c, remote-eb.c.
4941 Update `make saber_gdb' to work better.
4942
4943 * TODO: A woman's work is never done.
4944
4945 * cplus-dem.c, environ.c, inferior.h, infrun.c, inftarg.c,
4946 main.c, obstack.c, printcmd.c, remote-eb.c, remote-nindy.c,
4947 remote-vx.c, remote.c, solib.c, source.c, sparc-pinsn.c,
4948 sparc-tdep.c, sparc-xdep.c, symmisc.c, symtab.c, symtab.h
4949 target.c, terminal.h, tm-sparc.h, tm-sunos.h, utils.c,
4950 valops.c, valprint.c, exec.c: Lint.
4951
4952
4953 Wed Dec 12 23:44:15 1990 John Gilmore (gnu at cygnus.com)
4954
4955 Continuing Intel 960 port merge of GDB.
4956
4957 * Makefile.dist: Merge i960 "nindy-share" files. Rename
4958 malloc.h to gmalloc.h to avoid name conflicts in /usr/include.
4959 Don't ship gdb.dvi in tar file. Link gdb with init.o, not init.c.
4960 Wack over "make depend" so it handles files in subdirectories
4961 vx-share, nindy-share, bfd, and in the current directory.
4962
4963 * blockframe.c (get_prev_frame_info): Remove fatal error
4964 if stack not defined.
4965
4966 * core.c (core_open, core_detach): New functions that handle
4967 the old "core-file" command as "target core" and "detach" instead.
4968 (core_file_command): Call them.
4969 (core_xfer_memory): Use common routine xfer_memory.
4970
4971 * dbxread.c: Include a.out.gnu.h, not system a.out.h.
4972 dbxread now uses bfd for everything but symbol reading itself.
4973 BFD internals are used to drag out the relevant file offsets.
4974 (partial_symbol_file_open): Change args all around for BFD.
4975
4976 * symtab.c: Rename "value" to "val" everywhere, so we can
4977 #include "value.h".
4978 (symbol_file_command): New command, moved from dbxread.c
4979 and coffread.c. It uses BFD to read the file, then vectors
4980 based on its type, to dbx or coff symbol readers.
4981 * symtab.h: Extern a few vars for symbol_file_command.
4982
4983 * target.h: Breakpoint takes a char * save area, not a char **.
4984
4985 * valprint.c (val_print): When unpacking bitfields, offset
4986 the address in gdb of the value, if it is declared with a shorter
4987 type. Remove the last "runtime kludge test" of host byte order.
4988
4989 * utils.c: Remove old my_bfd_read routine.
4990
4991 * stack.c (frame_info): Use target_has_stack. Print program counter
4992 register's actual name rather than "pc", since it's called the
4993 "ip" (instruction pointer) on the i960 (sigh).
4994
4995 * target.c (target_command): Add command for selecting a target
4996 type and calling its open routine. This is used for initiating
4997 communication with a particular target, in a generic way.
4998
4999 * tm-i960.h: Update for modern gdb. Remove semicolons from
5000 various macros. Handle reading struct return convention, and
5001 error-out attempts to return structs with the "return" command.
5002 Be sure gdb doesn't think we know how to call functions in the
5003 inferior.
5004
5005 * i960-tdep.c: Rename FRAME_CHAIN_VALID and FRAME_FIND_SAVED_REGS
5006 to i960_xxx in lower case.
5007 (arg_address): Circumvent errors due to LOC_ARG_BLOCK
5008 not being defined yet.
5009
5010 * remote.c (remote_open): Call start_remote to initialize
5011 wait_for_inferior during open.
5012 (remote_xfer_inferior_memory): Return length written rather
5013 than errno value.
5014
5015 * remote-vx.c (target_command -> vx_open): Use new generic
5016 target command.
5017 * remote-eb.c, inftarg.c, exec.c: ditto.
5018
5019 * infrun.c: Fix comments.
5020 (attach_program -> child_open): Use new generic target command.
5021 (wait_for_inferior): Clear saved register values before target_wait,
5022 so target_wait can set some of them if convenient.
5023
5024 * infptrace.c (fetch_inferior_registers, store_inferior_registers):
5025 Return success indicator, not void.
5026 (child_xfer_memory): Avoid fetching initial word if we'll
5027 overwrite it anyway.
5028
5029 * infcmd.c (attach_command): Use new generic target open routine.
5030 (_initialize_infcmd): Update doc on attach and detach commands.
5031 (do_registers_info): Merge in a byte-order problem as a FIXME
5032 comment.
5033
5034 * findvar.c (find_saved_register): Avoid problem in current frame.
5035 (read_relative_register): Ditto.
5036 (write_register): Convert byte order on the way out.
5037
5038 * exec.c (file_command): Add.
5039 (add_to_section_table, exec_command): Use new bfd_map_over_sections.
5040 (xfer_memory): Common function between core_xfer_memory and
5041 exec_xfer_memory.
5042 (exec_xfer_memory): Use it.
5043
5044 * pn-opcode.h: Document that a "PN" is a Gould PowerNode.
5045
5046 * breakpoint.c, breakpoint.h, symtab.h, value.h, frame.h, utils.c,
5047 valops.c, stack.c, target.c, sparc-xdep.c, source.c, printcmd.c,
5048 infcmd.c, i960-pinsn.c, eval.c, defs.h: lint and gcc -Wall.
5049
5050 Sun Dec 2 16:45:06 1990 John Gilmore (gnu at cygnus.com)
5051
5052 Merge Intel 960 port of gdb, continuing...
5053
5054 * dbxread.c (partial_symbol_file_open, partial_symbol_file_read,
5055 symbol_file_command): Pass from_tty arg to hush 'em up.
5056
5057 * coffread.c (symbol_file_command): Avoid output if from_tty != 1.
5058 Add magic numbers for 960 COFF format.
5059
5060 Fri Nov 30 09:18:20 1990 John Gilmore (gnu at cygnus.com)
5061
5062 Merge Intel 960 port of gdb, from Intel "1.2" release.
5063
5064 CHANGE_LOG entries from their port, which was based on
5065 gdb+-2.8.0:
5066
5067 Thu Sep 6 11:02:22 PDT 1990
5068 Remove temp file if download is interrupted.
5069
5070 Wed Aug 1 09:08:33 PDT 1990
5071 Now uses binary protocol to talk to NINDY.
5072 Old hex protocol (NINDY 2.13 and older) supported with -O switch.
5073 Times out after 5 seconds when trying to talk to NINDY.
5074
5075 Tue May 29 12:54:49 PDT 1990
5076 Added variable baud rate (-b switch).
5077 Source code reorganization.
5078
5079 Thu Apr 26 11:09:55 PDT 1990
5080 More cleanup of batch mode; specifically, execute "-s", "-e", and
5081 "-se" switches as soon as they are encountered on the invocation line.
5082
5083 Fri Apr 20 13:47:15 PDT 1990
5084 Add -brk switch.
5085
5086 Thu Apr 19 09:54:28 PDT 1990
5087 Add 'reset' command.
5088
5089 Wed Apr 18 09:48:07 PDT 1990
5090 After opening remote tty, wait for 1 second to go by without input
5091 from it before trying to talk to NINDY (fixes problems with the
5092 Heurikon HK80/V960E).
5093
5094 Mon Apr 4 16:33:05 PDT 1990
5095 Some output was not being suppressed in 'batch' mode.
5096
5097 Thu Mar 22 15:31:11 PST 1990
5098 Ask user if old symbol table should be deleted when new file is
5099 downloaded.
5100
5101 Allow user to run a program downloaded before gdb960 was brought up.
5102
5103 Correct "exec-file" help message for i80960 context.
5104
5105 Correct bug in calculating user space address: could occasionally
5106 corrupt user program.
5107
5108 Make sure to zero low-order bits in rip's because of bug in 960CA
5109 A-step part: could cause operation faults when "next"ing across
5110 a function call.
5111
5112 Correct bug that made it impossible to get source line numbers for
5113 code loaded at addresses higher than 0x7fffffff.
5114
5115 Wed Jan 10 12:43:22 PST 1990
5116 Open remote tty for exclusive use.
5117
5118 Fri Jan 5 12:14:42 PST 1990
5119 Correct disassembly (CA manual was right after all):
5120 opcode for sysctl is 0x659
5121
5122 Mon Oct 23 12:03:04 PDT 1989
5123 Use G960BASE and G960BIN environment variables to find 'sx' utility.
5124
5125 Mon Oct 16 14:15:09 PDT 1989
5126 "sfr0"-"sfr31" should have been named "sf0"-"sf31"
5127
5128 Mon Oct 2 15:56:31 PDT 1989
5129
5130 Added 960CA disassembly support.
5131
5132 To simplify maintenance:
5133 - eliminated use of symblic links on pinsn.c: use i960-pinsn.c
5134 directly instead.
5135 - eliminated opcode.h: incorporates tables into i960-pinsn.c
5136 - moved 960-specific routines from i960-pinsn.c to i960-md.c
5137 - made disassembly interface identical to that in gdmp960.
5138
5139
5140
5141 Wed Nov 28 21:32:48 1990 John Gilmore (gnu at cygint)
5142
5143 * target.h: Allow targets to stack. Add target_has_memory,
5144 _registers, etc. Restructure memory access and "info files"
5145 to walk the target stack.
5146 * exec.c, core.c, inftarg.c, remote.c, remote-vx.c, remote-eb.c,
5147 target.c: Change tables to match target.h.
5148 * inflow.c (child_mourn_inferior): pop child_ops.
5149 (generic_mourn_inferior): Use new has_stack flag.
5150 * infptrace.c (child_xfer_memory): New memory regime.
5151 * inftarg.c (child_files_info): New "info files" regime.
5152 * remote-eb.c: New memory regime, new info files.
5153 * remote-vx.c: New memory regime, new info files. Now use
5154 separate targets for VxWorks attachment to machine, and
5155 actually running a process under VxWorks, since one has
5156 stack & execution & regs and the other doesn't.
5157 * remote.c: New memory regime, new info files.
5158 * sparc-xdep.c (fetch_core-registers): New memory regime.
5159 * target.c: New routines and support for stacked targets,
5160 new memory regime, new info files regime.
5161
5162
5163 Generalize section handling for an arbitrary number of sections,
5164 including use of the new BFD (binary file) library.
5165 * gdbcore.h: Add struct section_table.
5166 * exec.c (build_section_table): Iterate all sections and
5167 record what gdb needs to know about them.
5168 (exec_command): Use it.
5169 (exec_xfer_memory): Use the table.
5170 (exec_files_info): Print the table.
5171 * core.c (core_file_command, core_xfer_memory, core_files_info):
5172 Likewise.
5173 * source.c (find_source_lines): Use bfd_get_mtime.
5174 * dbxread.c: Quick changes to make it compile with new BFD.
5175 * utils.c (error): Avoid using bfd_error in generic routines.
5176
5177 * core.c (core_fetch_registers): Get from the ".regs" section of
5178 the BFD core file.
5179 * sparc-xdep.c (fetch_core_registers): Use the .regs info.
5180
5181 * inferior.h (attach_flag): Export.
5182 * infcmd.c (run_command): use new target_create_inferior.
5183 * infrun.c (child_create_inferior): Don't return result.
5184 * Makefile.dist (VERSION): 3.91.4.
5185
5186 Fri Nov 23 28:15:38 1990 John Gilmore (gnu at cygint)
5187
5188 * breakpoint.c (bpstat_num): Handle breakpoints which have
5189 since been deleted, such as temporary breakpoints.
5190 infcmd.c (program_info): ditto.
5191
5192 * core.c (core_file_command): Display the frame where the core
5193 dump occurred.
5194
5195 * main.c: lint.
5196
5197 * remote-vx.c (target_command): Merge in target command from
5198 targ-vx.c. A few other cleanups.
5199
5200 * TODO, Projects: Lots more stuff to do...
5201
5202 Fri Nov 23 18:15:38 1990 John Gilmore (gnu at cygint)
5203
5204 Massive changes to wall off the remote-debugging interface
5205 behind a function vector. The port to handle VxWorks targets
5206 is also part of this.
5207
5208 All files: Replace references to renamed functions,
5209 remove references to remote_debugging, remove references to
5210 have_include_file, have_core_file in favor of target_has_stack,
5211 target_has_memory, etc.
5212
5213 * Modularize the breakpoint interface.
5214 breakpoint.h (BREAKPOINT_MAX): New define sets max length of
5215 a breakpoint instruction.
5216 breakpoint.c: struct breakpoint's shadow_contents now sized as
5217 BREAKPOINT_MAX.
5218 (insert_breakpoints): Vector to target to install breakpoints.
5219 (remove_breakpoints): Vector to target here too.
5220 Remove REMOTE_SA_SPARC kludges and other remote_debugging.
5221 sparc-tdep.c (single_step): Use new breakpoint interface for
5222 the single-step breakpoints.
5223 mem-break.c (memory_insert_breakpoint, memory_remove_breakpoint):
5224 New file, contains routines to insert and remove breakpoints by
5225 reading out the old contents and later replacing them. This is
5226 how ptrace breakpoints work, and many remote systems as well.
5227
5228 * tm-vxworks68.h: New config file, overrides a few things for
5229 Wind River's preferences.
5230
5231 * target.h: New file, for transfer vector used to talk to the
5232 inferior (child, attached, core, exec, remote, etc). All accesses
5233 to the thing being debugged should come through these vectors.
5234 target.c: New file, routines to handle transfer vector.
5235 (various files): Add transfer vectors XXX_ops for the various
5236 targets and pseudo-targets (core files, etc) we support.
5237
5238 * breakpoint.c (bpstat_stop_status): Further explorations of
5239 watchpoints and why things don't work all the time.
5240 (bpstat_alloc): New fn to allocate a bpstat and chain it.
5241
5242 * config.gdb: Only add "source ${srcdir}/.gdbinit" to
5243 the local gdbinit if it doesn't already have it.
5244
5245 * core.c (core_ops): add and install.
5246 Allow core debugging without exec file.
5247
5248 * dbxread.c (free_and_init_header_files): Merge two fns.
5249 (end_symtab): Free named symbol table when a new version comes in.
5250 (read_dbx_symtab): Relocate all kinds of symbols with base
5251 address. First step toward handling different text, data, bss
5252 reloc.
5253 (add_file_addr_command): Renamed add_file_command.
5254 (add_file_command): Vector to remote handler.
5255 Add "load" as an alias for "add-file" command.
5256
5257 * defs.h: Allow "volatile" to be used in non-ANSI; use it for
5258 non-returning functions.
5259
5260 * exec.c: Add exec_ops, and push it as a target when an exec
5261 file is specified.
5262
5263 * infcmd.c (run_command): Pass executable file name and arg list
5264 separately when starting an inferior. Permit "run" when no exec
5265 file is specified, for VxWorks.
5266 (detach_command): Move to child_detach in inftarg.c.
5267
5268 * inftarg.c: New file. Unix-child-specific routines, and the
5269 child_ops structure.
5270
5271 * inferior.h (registers): Export "registers" as the way for
5272 target dependent register handlers to find gdb's local copy of
5273 the registers. Rename "stop_after_attach" to "stop_soon_quietly"
5274 since it is now used by places that want wait_for_inferior to
5275 handle the grunge but want to see every trap from the inferior.
5276
5277 * inflow.c (create_inferior): Pull out, and merge into infrun.c.
5278 Eliminate remote_debugging hooks in terminal handling.
5279
5280 * infrun.c: Replace start_inferior with child_create_inferior.
5281 Move all the hair of Unix shells and ptrace idiosyncracies into
5282 child_create_inferior, so remote handlers don't have to deal.
5283 Remove running_in_shell. Rename stop_after_attach to
5284 stop_soon_quietly, and use it in a few other places where we want
5285 to just call wait_for_inferior and get control back on the first
5286 trap. trap_expected now never takes a value > 1.
5287 (init_wait_for_inferior): Initialize static vars when a new
5288 process is created.
5289
5290 main.c (gdbinit): Add new hook for .gdbinit file name, let
5291 it be overridden by config files as GDBINIT_FILENAME.
5292 (DEFAULT_PROMPT): Add new hook for overriding (gdb) prompt.
5293 Both of these are used for VxWorks gdb.
5294
5295 mcheck.c: rename include file "gmalloc.c" to avoid problems
5296 with system include file "malloc.c".
5297
5298 param-no-tm.h: New include file, same as param.h but does not
5299 include the default "tm.h" file. This is used in files where
5300 the target is known, e.g. remote-eb.c or sparc-xdep.c.
5301
5302 param.h: Now just a shell that includes tm.h and param-no-tm.h.
5303
5304 remote-vx.c: New file, VxWorks remote debugging support. Uses
5305 RPC routines that are shared with the target system, in directory
5306 ${srcdir}/vx-share.
5307
5308 remote.c: Vectorize remote interface.
5309
5310 source.c: Globalize source_path, and make an alias "l" for "list"
5311 since we now have the "load" command.
5312
5313 sparc-xdep.c: Use new param-no-tm.h.
5314
5315 symmisc.c (free_named_symtab): Add new function from Wind River.
5316 However, ifdef it out for now while we think about what it should
5317 really be doing.
5318
5319 tm-sun3.h, xm-sparc.h, xm-sun3.h, xm-symmetry.h: Move
5320 PREPARE_TO_STORE to
5321 the xm- file, and change its name to CHILD_PREPARE_TO_STORE, since
5322 non-Unix-children handle this with their own code in the target
5323 transfer vector.
5324
5325 Makefile.dist: Roll version to 3.92.3. Add vx-share stuff to
5326 source and target lists. Add vx-share to default list of include
5327 directories. Add new files to src and target lists: mem-break,
5328 target, inftarg, remote-eb, remote-vx, targ-vx. Be sure the
5329 ${srcdir} versions of munch and createtags are used.
5330
5331 * valops.c (find_function_addr): Split out of call_function.
5332 (call_function_by_hand): Rename call_function; this function
5333 calls functions in the target by laboriously patching the target
5334 word-by-word with the right stack, args, regs, etc.
5335
5336
5337 Mon Nov 5 17:29:10 1990 John Gilmore (gnu at cygint)
5338
5339 Handle AMD 29000 a bit better.
5340
5341 * remote-eb.c (readchar): Mask received char log to make it readable.
5342 (remote_start): Pass arguments down to executing program.
5343 Make startaddr unsigned.
5344 infrun.c (start_inferior): Accept args, pass them to
5345 remote_start.
5346 infcmd.c (run_command): Pass args down to start_inferior.
5347
5348 * tconfig/am29k-aout, tconfig/am29k-coff: New files specifying
5349 the target object file format.
5350 tm-29k.h: Pay heed to COFF_ENCAPSULATE.
5351
5352 * am29k-pinsn.c (print_insn): Print 0x on hex numbers in disassembly.
5353 am29k-tdep.c (examine_prologue): Better checking of function prefixes.
5354
5355 Sun Oct 7 18:20:45 1990 John Gilmore (gnu at cygint)
5356
5357 * Makefile.dist (VERSION): Roll version to 3.91.9 and freeze.
5358 * TODO: We did a few things, we have more to do though.
5359
5360 * xm-sparc.h (CLEAR_DEFERRED_STORES): Define.
5361 * inflow.c (inferior_died): Clear deferred stores.
5362
5363 * Debug problems with dummy frames and calls to the inferior.
5364 * tm-sparc.h (PUSH_DUMMY_FRAME, POP_FRAME): Move to sparc-tdep.c.
5365 * sparc-tdep.c (do_restore_insn): Simplify.
5366 (sparc_frame_find_saved_regs): Simplify and fix what we find.
5367 (sparc_push_dummy_frame): Simplify and fix what we push.
5368 (sparc_pop_frame): Slightly more hair here, deciding whether
5369 we are restoring a saved PC or returning to a return address in %i7.
5370 * sparc-xdep.c (read_inferior_registers): Debug if valid reg is read.
5371
5372 * utils.c (xmalloc, xrealloc): Return type depends on __STDC__.
5373 * symtab.h (xmalloc): ditto, for obstack_chunk_alloc.
5374 * obstack.h (chunkfun): ditto.
5375 * defs.h (xmalloc, xrealloc): ditto
5376
5377 * utils.c (quit): Grab the terminal from the child if necessary.
5378
5379 * inflow.c (term_status_command): Rename to term_info, change
5380 to "info terminal".
5381
5382 * sparc-pinsn.c (print_insn): Disassembly prefers real instructions.
5383 (is_delayed_branch): Speed up.
5384 * sparc-opcode.h: Add ALIAS bit to aliases. Fix up opcode tables.
5385 Still missing some float ops, and needs testing.
5386
5387 * Support for input and output radixes other than base 10
5388 * defs.h (input_radix, output_radix): Declare.
5389 * expread.y (yyparse, parse_number): Handle changes of input
5390 radix, and ambiguous names-or-numbers in radixes >10.
5391 * printcmd.c (print_scalar_formatted): Print formatted hex
5392 numbers in varying column widths.
5393 * valprint.c (val_print): Use output_format to print scalar ints.
5394 (set_input_radix, set_output_radix, set_radix): Create.
5395 (set_output_radix): Set output_format from output_radix.
5396 (_initialize_valprint): add `set radix' but leave the others off.
5397
5398 * main.c (execute_command): Let stupid questions be turned off.
5399 (_initialize_main): Handle "set stupidity", etc.
5400
5401 * main.c, inflow.c, inferior.h, frame.h, command.c, defs.h,
5402 sparc-pinsn.c, sparc-xdep.c, value.h, valops.c, values.c: Lint.
5403
5404 Tue Oct 2 11:20:02 1990 John Gilmore (gnu at cygint)
5405
5406 * TODO, Makefile.dist, ChangeLog: Freeze for 3.91.8 release.
5407 bfd stuff is still screwed up, but with some manual work, it
5408 compiles.
5409
5410 * breakpoint.c (bpstat_do_actions): Start over if a command
5411 proceeds the inferior, since the inferior will have stopped and
5412 will need to have its new stop-actions taken care of.
5413
5414 * dbxread.c (read_struct_type): Expression gives Sun3 4.0.3
5415 compiler fits, simplify it.
5416
5417 * gdb.texinfo (directory command): Doc new dir command.
5418 source.c (directory_command): "dir" now puts things on the front
5419 of the path, moves dups up front, and handles multiple names
5420 on the command line, inserting each one in order. It also
5421 blows away cached line and full_filename info.
5422
5423 * stack.c (backtrace_command): Skip "more stack frames follow"
5424 unless interactive.
5425
5426 * Change #ifndef HAVE_VPRINTF to #define MISSING_VPRINTF in
5427 xm-convex.h, xm-hp300bsd.h, xm-isi.h, xm-merlin.h, xm-news.h,
5428 xm-np1.h, xm-pn.h, xm-pyr.h, xm-symmetry.h, xm-umax.h, xm-vax.h.
5429 The only odd one was Gould NP1, which had defined vprintf to
5430 "printf"!!!
5431
5432 * Merge Ted Goldstein <tedg@Eng.sun.com>'s changes for epoch.
5433 printcmd.c (print_command_1): Pass 'inspect' flag down as a global
5434 variable, inspect_it.
5435 valprint.c (print_string, val_print): Use the global inspect_it
5436 to indicate whether to print in Epoch style or normal style.
5437
5438 Mon Oct 1 23:55:26 1990 John Gilmore (gnu at cygint)
5439
5440 * printcmd.c (call_command): add an alias for the "print" command
5441 which runs expressions and doesn't print the result if void.
5442 (print_command_1): implement it.
5443
5444 * command.c: Remove #if 0'd code. Initialize all the fields
5445 in add_cmd (). Rename do_nothing_command to
5446 not_just_help_class_command, and make it externally visible.
5447 command.h: add user_commands to struct.
5448 * main.c (define_command): Don't overload c->function with a char
5449 string as well as a function pointer.
5450
5451 * eval.c (evaluate_subexp): Reinstall tiemann changes to
5452 calling convention of value_struct_elt () that got dropped in
5453 merge.
5454
5455 * tm-sparc.h (FRAME_FIND_SAVED_REGS): move to sparc-xdep.c.
5456 sparc-tdep.c (sparc_frame_find_saved_regs): ditto.
5457
5458 * tm-sparc.h (POP_FRAME): replace some constants with defines.
5459
5460 * sparc-xdep.c (store_inferior_registers): defer stores to regs
5461 until a good time (e.g. when we are about to run the child),
5462 saving ptrace calls.
5463 * infrun.c (proceed): handle DO_DEFERRED_STORES.
5464 * tm-sparc.h: define DO_DEFERRED_STORES.
5465
5466 * sparc-xdep.c (store_inferior_registers): when storing float
5467 registers, don't store stack regs too. When storing the SP,
5468 however, DO store the stack regs too. This fixes a bug in which
5469 the dummy frame is not recognized when a call_function finishes,
5470 because its frame pointer (in the stack regs) was never
5471 initialized.
5472 (read_inferior_registers): Mark WIM and TBR and FPS and CPS valid
5473 even though we don't know how to read them from an inferior.
5474 valops.c (call_function): Comment about storing SP.
5475
5476 * infrun.c (save_inferior_status): Save away the original bpstat
5477 chain so it can be restored later. Install the copied version for
5478 use by whoever saved the status. It will be blow away by
5479 restore_inferior_status, and the original chain restored. This is
5480 important for people who have pointers into the original.
5481
5482 * breakpoint.c, command.h, copying.awk, dbxread.c, defs.h,
5483 findvar.c, frame.h, obstack.h, obstack.c, inflow.c, value.h,
5484 main.c, printcmd.c, sparc-tdep.c, symtab.c, valprint.c: lint
5485
5486
5487 Fri Sep 28 20:32:46 1990 John Gilmore (gnu at cygnus.com)
5488
5489 * Makefile.dist: Roll version to 3.91.8. Add bfd.h and bfdconfig.h
5490 temporarily to the makefile. Add am29k-opcode.h and WHATS.NEW.
5491 Add stuff.c and kdb-start.c to the OTHERS list for tar files.
5492
5493 Fri Sep 28 19:12:12 1990 John Gilmore (gnu at cygint)
5494
5495 * Merge Mike Tiemann's multiple inheritance changes from Sun.
5496 Store the baseclasses in a type struct starting from array element
5497 0 rather than from the unusual array element 1.
5498
5499 dbxread.c: the above.
5500 (virtual_context): Add
5501 Read new debug information about which virtual function table
5502 a virtual function is from, and store it in fn_field.fcontext.
5503
5504 symtab.h: Add fcontextt. Fix baseclass indices. Typo in
5505 TYPE_FN_FIELD_STATIC_P.
5506
5507 symtab.c: the above.
5508 valops.c: the above. Handle pointer casts of object *'s.
5509 (search_struct_method): Add.
5510 (value_struct_elt): First arg is now a pointer to a value, and is
5511 modified on return.
5512
5513 valprint.c: the above.
5514 values.c (value_virtual_fn_field): Add type arg. Handle
5515 offsetting to the proper object when calling virtual fns.
5516 The above.
5517 (baseclass_addr): Add valuep arg.
5518
5519 * README: Document the current state of BFD config (missing).
5520 * TODO, ChangeLog, Makefile.dist: Roll version.
5521 * WHATS.NEW: Add summary of changes since 3.5.
5522
5523 Thu Sep 27 16:23:12 1990 John Gilmore (gnu at cygint)
5524
5525 * dbxread.c (read_struct_type): Clear bit vectors whenever
5526 we allocate one.
5527 symtab.c (B_CLRALL): define.
5528
5529 * tm-sparc.h (STORE_RETURN_VALUE): Avoid clobbering types by
5530 using == rather than =. Huh... This fixes the dreaded problem
5531 wherein builtin_type_int becomes TYPE_CODE_FLT.
5532
5533 * core.c (info_files): Show the inferior pid.
5534
5535 * config.gdb: Avoid putting "dir" command into .gdbinit. GDB
5536 already knows how to look in the source directory.
5537
5538 * Remove psymtab hair from many places. Remove duplicated code
5539 for searching symbol tables. Hide psymtabs from most places.
5540 Make it fast to get from a psymtab to its symtab.
5541
5542 blockframe.c (blockvector_for_pc): Remove psymtab hair.
5543 coffread.c (psymtab_to_symtab): Rename to psymtab_to_symtab2.
5544 mipsread.c (psymtab_to_symtab): Rename to psymtab_to_symtab2.
5545 dbxread.c: export psymtab_to_symtab, make it work if called N times.
5546 (psymtab_to_symtab): Rename to psymtab_to_symtab2. Initialize
5547 new symtab completely. New psymtabs get symtab pointer
5548 initialized to zero. Remove MI warning printf.
5549 symtab.h: Comments. Add psymtab to symtab pointer.
5550 (PSYMTAB_TO_SYMTAB): New macro.
5551 symtab.c: use PSYMTAB_TO_SYMTAB. Add psymtab_to_symtab and export it.
5552 source.c: use PSYMTAB_TO_SYMTAB. Remove symtab version and
5553 compilation fields.
5554 stack.c (backtrace_command): Avoid pre-pass to read symbols, if
5555 verbose is not set.
5556 (print_frame_info): Avoid special-casing symbols that have not yet
5557 been read in.
5558
5559 * source.c (open_source_file): Quick path if we have already
5560 located the source file by its full name.
5561
5562 * symtab.c (lookup_symbol): Use find_pc_symtab rather than
5563 find_pc_psymtab. When a name is found in the misc function
5564 vector, search the symbol table for its mangled name, not the
5565 name that the user typed.
5566
5567 * bfd.h: Fix missing comment terminators, make #endifs match.
5568
5569 * valarith.c (value_less): Handle unsigned int comparisons.
5570 Add FIXME about pointer compares, which assume host and target
5571 pointers are the same.
5572
5573 * command.c (do_nothing_command): lint
5574 dbxread.c: lint. Remove sort_syms. Document C++ visibility info,
5575 fix comments on debug symbol format for visibility. Actually set
5576 visibility of symbols.
5577 main.c (echo_command): lint; use <readline/history.h>.
5578 tm-sparc.h (FRAME_FIND_SAVED_REGS): lint
5579 obstack.h (_obstack_blank): Rearrange pointer math to avoid
5580 pointing past end of allocated memory; saber complains.
5581 obstack.h: Declare the external functions that we use.
5582 valarith.h: use <string.h>
5583 solib.c (solib_add): lint.
5584
5585 Fri Sep 21 17:05:19 1990 John Gilmore (gnu at cygint)
5586
5587 * main.c (initialize_main): Default info_verbose to off, now that
5588 symbol reading is fast.
5589 (quit_command): Avoid clobbering exec_bfd while quitting.
5590
5591 * Initial BFD (binary file diddling library) merger:
5592 coffread.c: Change AOUTHDR to struct exe_hdr.
5593 dbxread.c: ditto.
5594 core.c: initialize initialized data at compile time.
5595 (core_file_command): Move from coredep.c, convert to bfd.
5596 (xfer_core_file): Convert to bfd.
5597 exec.c (exec_file_command): use bfd routines.
5598 gdbcore.h: BFD.
5599 mips-tdep.c: Remove exec_file_command and friends.
5600 source.c: bfd.
5601
5602 * coredep.c: (fetch_core_registers) Convert core_file_command to
5603 fetch_core_registers.
5604 mips-xdep.c, sparc-xdep.c, sun3-xdep.c: ditto.
5605
5606 * utils.c: (error): Bogus crap, FIXME, to print bfd errors.
5607 (my_bfd_read): More bogosity, which I don't think we call.
5608 (program_name): Remove this atrocity asap!
5609
5610 Wed Sep 19 13:36:41 1990 John Gilmore (gnu at cygint)
5611
5612 * From Per Bothner:
5613 values.c: allocate_repeat_value was not clearing the
5614 optimized_out field.
5615 (value_static_field): minor stylistic fix (wrong macro was used).
5616 valops.c (value_struct_elt_for_address): didn't work for C++
5617 static fields.
5618
5619 * signame.c (_initialize_signame): Initialize signal names once.
5620
5621 * breakpoint.h, command.c, copying.awk, defs.h, environ.c,
5622 exec.c, frame.h, infcmd.c, inferior.h, main.c, munch, sun3-xdep.c,
5623 symtab.h, tm-29k.h, valprint.c, value.h, values.c: Lint.
5624
5625 * remote-eb.c: Support user-settable baud rates on the serial port.
5626
5627 * tm-sun3.h (PREPARE_TO_STORE): fix typo.
5628
5629 Fri Sep 14 13:28:29 1990 John Gilmore (gnu at cygint)
5630
5631 * tconfig/sun3os4: Remove warning about native assembler,
5632 since it also occurs in the xconfig file.
5633
5634 * findvar.c (registers): Allocate some slop after `registers'
5635 to prevent stray accesses from trashing the next variable.
5636
5637 * tm-68k.h (REGISTER_BYTES): Allocate the right number of bytes
5638 on the sun-3, by changing the #ifdef from `sun3' (which is not
5639 defined by cc) to `sun'. Symptom was trashed builtin_type_XXX
5640 vars, which happened to follow `registers' in the executable.
5641
5642 * readline/history.c (history_search): Heed gcc-2's advice
5643 and parenthesize && inside ||).
5644
5645 * am29k-opcode.h, am29k-pinsn.c, am29k-tdep.c, remote-eb.c,
5646 tm-29k.c: Insert FSF copyright headers.
5647
5648 * remote-eb.c: Better comments.
5649
5650 * Makefile.dist: Update to 3.91.6.
5651 * TODO: note PREPARE_TO_STORE problem.
5652
5653 Thu Sep 13 09:52:33 1990 Jim Kingdon (kingdon at cygint)
5654
5655 * stack.c (frame_info): Only use FRAME_FIND_SAVED_REGS if defined.
5656
5657 * remote.c: Wrap the whole file in #if !defined (SPECIAL_REMOTE).
5658
5659 * infrun.c (wait_for_inferior, at end): Don't set up
5660 prev_* if the inferior no longer exists.
5661
5662 * inferior.h (CALL_DUMMY_LOCATION): New macro, to replace
5663 CANNOT_EXECUTE_STACK.
5664 valops.c (call_function): Use it.
5665
5666 * tm-convex.h: Add CALL_DUMMY_LENGTH for use by PC_IN_CALL_DUMMY.
5667
5668 * inferior.h (PC_IN_CALL_DUMMY): New macro.
5669 infrun.c (wait_for_inferior, 2 places): Use it.
5670
5671 * values.c (value_being_returned): Only use
5672 EXTRACT_STRUCT_VALUE_ADDRESS if defined.
5673
5674 * Move PREPARE_TO_STORE from xm-sun3.h to tm-sun3.h to do the
5675 right thing for remote-eb.c.
5676
5677 * sun3-xdep.c: Remove extraneous call to remote_store_registers.
5678 * sun386-xdep.c, hp300hpux-xdep.c, sparc-xdep.c: Ditto.
5679
5680 * blockframe.c: Put get_frame_saved_regs inside #if !defined
5681 (FRAME_FIND_SAVED_REGS).
5682
5683 * findvar.c ({fetch,store}_registers): Check for
5684 REMOTE_{FETCH_STORE}_REGISTER macro.
5685
5686 * findvar.c (get_saved_register): Add argument lval and
5687 change meaning of argument addr.
5688 findvar.c: Change calls to get_saved_register to reflect
5689 new calling convention.
5690 valops.c (value_assign): Use get_saved_register instead of
5691 find_saved_register.
5692
5693 Sun Sep 2 12:40:20 1990 Jim Kingdon (kingdon at cygint.cygnus.com)
5694
5695 * coffread.c (read_one_sym): Make temp_aux an AUXENT, not
5696 an (uninitialized) pointer to one. Use "&" when passing it
5697 to fread.
5698
5699 Fri Aug 31 22:57:54 1990 Jim Kingdon (kingdon at cygint.cygnus.com)
5700
5701 * coffread.c (getfilename): Use DGUX x_offset and x_name if
5702 defined.
5703
5704 * coffread.c (symbol_file_command): Put semicolon after
5705 "int from_tty".
5706 Put safe_to_init_tdesc_context in #if defined (TDESC).
5707 Put #ifdef TDESCs in 1st column for non-ANSI cpp's.
5708 coffread.c: #include <sys/stat.h>.
5709 (read_coff_symtab): Typo: in_source_files -> in_source_file.
5710 Add missing ')' in check for "lc%" and friends. Remove
5711 extraneous '}'.
5712 Declare read_one_sym() at top of file.
5713 (read_file_hdr): Put in extra #ifdefs so MC68MAGIC and
5714 MC68WRMAGIC can have the same value without causing a duplicate
5715 case.
5716
5717 Thu Sep 13 15:55:36 1990 John Gilmore (gnu at cygint)
5718
5719 * Allow a Makefile to be built without building the
5720 tm and xm file links that screw up builds in subdirectories.
5721 This is done with `config.gdb none', then you can do things
5722 like `make gdb.tar.Z'.
5723 * tconfig/none: Config file for no target system
5724 * xconfig/none: Config file for no host system
5725 * config.gdb: If no TM or XM files are called out by the
5726 host or target file, don't make links for them.
5727
5728 * cplus-dem.c: Add documentation.
5729
5730 * dbxread.c (read_ofile_symtab): Turn a fatal error into a
5731 simple error, so the user's gdb doesn't crash due to some object
5732 file problem (e.g. somebody is rebuilding the file out from under
5733 gdb).
5734
5735 * printcmd.c (print_address_symbolic): demangle the symbol.
5736
5737 * Makefile.dist (OTHERS): Remove tdesc-lib because it has
5738 Motorola copyrights in it. Make "make gdb.tar.Z" work.
5739 (alldeps.mak): sort and uniq all results from this; duplicates
5740 hose gdb.tar.Z link building. Remove RCS files from
5741 tconfig and xconfig. Add config files for sun386. Add
5742 a few odd files to OTHERS and HFILES.
5743
5744 Mon Sep 10 21:20:24 1990 John Gilmore (gnu at cygint)
5745
5746 * Makefile.dist: Pull solib.c to tconfig/sun?os4.
5747 Roll version number to 3.91.5. Make lint work in bindir.
5748
5749 * README: Document cross-debugging and new file structure.
5750
5751 * blockframe.c: Lint. Include "value.h" to declare read_register.
5752 (find_pc_partial_function): remove duplicate line.
5753
5754 * command.h: Lint. Declare error_no_arg and dont_repeat.
5755
5756 * tm-news.h: Remove inadvertently duplicated stuff.
5757
5758 * mipsread.c: Remove cache_pc_function stuff, now done cleanly.
5759 Clean up usage of misc_function_type. Declare some CORE_ADDRs.
5760
5761 * config.gdb: Allow `config.gdb host target' form. Clean
5762 up previous change that printed bogus messages when you just said
5763 `config.gdb'.
5764
5765 * core.c: #include "command.h" for lint.
5766 * dbxread.c: lint
5767 * eval.c: lint
5768 * main.c: Remove some casts of enums. Lint.
5769 * source.c: lint
5770 * symtab.c: lint
5771 * symtab.h: lint
5772 * expread.y: lint
5773 * valarith.c: lint
5774
5775 * printcmd.c (initialize_printcmd): Fix thinko in inspect cmd.
5776
5777 * sparc-tdep.c (isannulled): Take instruction as parameter, don't
5778 read it from memory. This will allow us to save ptrace calls
5779 eventually. Changed caller single_step too.
5780
5781 * sparc-xdep.c (fetch_inferior_registers): Avoid reading regs
5782 that we aren't going to use, saving many ptrace calls, especially
5783 when watchpointing or single stepping. Use some #define's for
5784 constants.
5785 (store_inferior_registers): Ditto.
5786 (core_file_command): Use some #define's for constants.
5787
5788 * tm-sparc.h: Add #define's for some register numbers, so we
5789 can eliminate the use of random constants in sparc-xdep.c.
5790
5791 * stack.c (frame_command, print_frame_info, up_command,
5792 down_command) Remove frame_changed, since it
5793 causes a bug and doesn't seem to do anything useful. In some
5794 places it was used as a flag, in others as a stack level (?).
5795
5796 * utils.c: Use MISSING_VPRINTF rather than HAVE_VPRINTF, so the
5797 default is to use the portable (vprintf) version rather than the
5798 kludge version.
5799 * xm-news.h (MISSING_VPRINTF): Add.
5800
5801 * valprint.c (val_print): Demangle fancy vtbl printouts. Lint.
5802
5803 Sat Sep 8 00:24:12 1990 John Gilmore (gnu at cygint)
5804
5805 * Remove stuff that forces -Bstatic linking of gdb, and warnings
5806 about linking debugged programs -Bstatic in the sun?os4 config
5807 files in tconfig and xconfig subdirectories.
5808
5809 * main.c (main): Remove unreached exit(0) now that we exit
5810 via quit_command().
5811
5812 * Create TODO file for online bug list. There are too many
5813 "little" bugs to keep track of on paper.
5814
5815 * Change Projects file to refer to bug-gdb@cygnus.com
5816 rather than kingdon@ai.
5817
5818 Fri Sep 7 23:35:15 1990 John Gilmore (gnu at cygint)
5819
5820 * Makefile.dist (VERSION): 3.91.4 now.
5821
5822 * symtab.c (init_misc_bunches): Rename from init_misc_functions.
5823 (condense_misc_bunches): Add sanity check that misc_count is
5824 the same as the number of symbols in the bunch.
5825
5826 * coffread.c: rename init_misc_bunches. Pass an argument
5827 to condense_misc_bunches (a zero).
5828
5829 * dbxread.c (partial_symbol_file_read): Call init_misc_bunches
5830 every time we are called; don't rely on our caller to do it.
5831 (add_file): Remove call to init_misc_bunches.
5832
5833 * mipsread.c: Only warn, don't error, if unknown symbol types.
5834 This keeps an old gdb from falling on its face if it sees newly
5835 extended symbol info. Rename init_misc_bunches.
5836
5837 Fri Sep 7 22:58:15 1990 John Gilmore (gnu at cygint)
5838
5839 * Merge in changes from Per Bothner for DECstations and other
5840 MIPS stuff. The rest is Bothner speaking:
5841
5842 The next message is a merger of Alessando Forin's mips port with
5843 mine. I've tried to use my good if biased judgment to get
5844 the best of both. It *does* need testing.
5845
5846 Some of the changes are general, *not* mips-specific.
5847
5848 param.h:
5849 Didn't believe in little-endian bit order.
5850 There are still inconsistencies about whether flags
5851 like BITS_BIG_ENDIAN are integer (#if ...) or
5852 boolean (#ifdef ...). I tried to paper over them.
5853
5854 dbxread.c,coffread.c,mipsread.c,symtab.c,symtab.h:
5855 Moved some misc_function code that was common to
5856 {dbx,coff,mips}read.c to symtab.c.
5857 In the process, I think I cleaned things up a bit.
5858 At the same time, moved obsavestring and obconcat to symtab.c.
5859
5860 dbxread.c:
5861 Removed obsolete condense_addl_misc_bunches (use
5862 condense_misc_bunches(1) instead).
5863
5864 exec.c:
5865 Needed to include <sys/dir>, at least on DECstations.
5866
5867 valops.c, mips-tdep.c, tm-mips.h:
5868 Added PUSH_ARGUMENTS macro to support funny argument-pushing
5869 conventions (when STACK_ALIGN is insufficient).
5870 Needed on mips, where doubles need 8-byte alignment,
5871 but ints only need 4.
5872
5873 mips-opcode.h:
5874 Removed cruft that was not being used.
5875 Merged in many fixes (most from Frank Yellin, fy@lucid.com).
5876
5877 mips-pinsn.c:
5878 Print $ before register-names (I think that makes things a little
5879 more consistent).
5880 Never print two instructions, even if one delays.
5881 Removed hex-disassemble set_cmd. (This is not mips-specific,
5882 so I think the argument is whether it is generally worthwhile or not.
5883 I'm inclined to think not, given how easy it is to
5884 convert between radixes in gdb.)
5885
5886 mipsread.c:
5887 This is basically Alessando's code.
5888 It doesn't use obstacks; I changed it to use obstacks
5889 in a few minor places where using malloc causes a
5890 memory leak. (Probably, more places could/should be changed.)
5891 I added record_misc_function where it was missing.
5892 In symbol_file_command and add_file_command, I tried
5893 to make the code consistent with more recent versions.
5894 Minor sylistic changes in parse_procedure.
5895 Make a .gdbinfo. psuedo-symbol point back to the real
5896 procedure symbol (using the isym field).
5897
5898 mips-tdep.c:
5899 This is basically from my port, but with a lot of details
5900 and a number of routines merged in from Alessando's version.
5901 I basically used my code "raw" backtrace (use heuristics
5902 from the actual code, rather than symbol table info) - though
5903 the idea is Alessandro's. I feel my code is a little cleaner
5904 here, particularly in being a little more flexible, such as being
5905 able to handle gcc-produced code (which it now can).
5906 It also doesn't do frame caching (which is not useful
5907 more recent gdb versions).
5908 I also used my code for push_/pop_dummy, more or less.
5909 I tried to incorporate AF's code for testing sigtramp
5910 while backtracing; I probably got it wrong.
5911 Added mips_print_register, which tries to scrunch as much
5912 information as possible on a screen...
5913 Removed the skip-prologue set_cmd. As with hex-disassemble (see
5914 under mips-pinsn.c), I don't see anything mips-specific here,
5915 and I don't see it being all that useful anyway.
5916
5917 tm-mips.h:
5918 Added a $fp psuedo-reg distinct from $fp (nice for gcc).
5919 Use more register names (rather than hard-cases numbers).
5920
5921 Thu Sep 6 18:33:15 1990 John Gilmore (gnu at cygint)
5922
5923 * Hack up 3.90.11 changes:
5924
5925 * Makefile.dist (depend): parameterize $(GCC).
5926 Add solib.c and solib.o.
5927 (readline): Fix vpath for both absolute or relative SRCDIR.
5928
5929 * blockframe.c: Fix from Schaefer@asc.slb.com for shared libs.
5930 Also, let the part I didn't understand at least compile so
5931 I can test the rest. FIXME.
5932
5933 * dbxread.c: Fix thinko using strcmp.
5934 (init_psymbol_list): declare static.
5935 (partial_symbol_file_open): Comment cleanups better, avoid
5936 cleaning up the string table since the caller will do that.
5937 Move the stat for mod time into symbol_file_command, temporarily.
5938 (There should be a mod time for each symbol file, eventually,
5939 to control its rereading. FIXME.)
5940
5941 * infptrace.c (PT_WRITE_D): use same value as PT_WRITE_I for
5942 SunOS, which gives error for shared libs otherwise. (From
5943 Schaefer, probably FIXME needs work for portability.)
5944
5945 * solib.c: Move #include "param.h" to work.
5946 Lowercase all the Uppercase Letters In the Messages.
5947 (find_solib): Clean up inferior_so_name for debug printouts.
5948 Allow no argument, to mean all shared libraries.
5949
5950 * symmisc.c: include param.h to get CLEAR_SOLIB.
5951
5952 Wed Sep 5 18:00:08 1990 John Gilmore (gnu at cygint)
5953
5954 * Merge in Kingdon's changes from FSF: the diffs from 3.90.9
5955 to 3.90.11. ChangeLog entries below are from this.

6012
6013 * breakpoint.c (enable_breakpoint): Get value of watchpoint.
6014
6015 * defs.h [sparc]: Use <alloca.h> regardless of __GNUC__.
6016
6017 * values.c (USE_STRUCT_CONVENTION): Check for structures of
6018 size 1,2,4,8 rather than size < 8.
6019
6020 * dbxread.c (dbx_lookup_type): Do f->length *= 2 as many times
6021 as necessary, not just once.
6022

6034
6035 Tue May 15 21:27:12 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
6036
6037 * source.c (find_source_lines) [BROKEN_LARGE_ALLOCA]: Use xmalloc.
6038
6039 * sparc-opcode.h: Change all store floating-point state register
6040 instructions to have the right match & lose fields.
6041
6042 Sat May 5 12:39:18 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
6043
6044 * Makefile.dist: Move -I${srcdir} to GLOBAL_CFLAGS and pass
6045 VPATH to readline.
6046 config.gdb: If srcdir != ., create readline directory and
6047 copy a makefile into it.
6048
6049 * wait.h, infrun.c: Change WRETCODE to WEXITSTATUS for
6050 consistency with POSIX.
6051
6052 * breakpoint.c (bpstat_stop_status): Disable watchpoint
6053 when we exit its exp_valid_block.
6054
6055 Tue Sep 4 11:46:46 1990 John Gilmore (gnu at cygint)
6056
6057 * Makefile.dist: Bump version to 3.91.3.
6058

6060 Prompted by Tiemann bug report "cont 10" doesn't work any more.
6061
6062 inferior.h: Add breakpoint_proceeded to inferior status struct
6063 and globals; save it and restore it.
6064 (clear_breakpoint_commands): Cleanup, remove old #define.
6065
6066 infrun.c (clear_proceed_status): Set breakpoint_proceeded.
6067 (save_inferior_status, restore_inferior_status): handle it also.
6068 (proceed): Remove earlier code that set breakpoint_proceeded.
6069 It is now set only in clear_proceed_status.
6070 (clear_proceed_status): Cleanup, use bpstat_clear rather
6071 than clear_breakpoint_commands. No callers need the stop_bpstat
6072 between clear_proceed_status and proceed.
6073
6074 infcmd.c: Add breakpoint_proceeded definition and comment.
6075 (cont_command, jump_command, signal_command): Move call to
6076 clear_proceed_status right next to call to proceed.
6077
6078 breakpoint.c (bpstat_do_actions): Avoid clobbering our
6079 caller's argument while running down the chain of breakpoints.
6080 Use new variable "breakpoint_proceeded" to determine when
6081 a command that it executes moves the inferior past the
6082 breakpoint.
6083 (bpstat_clear): Handle NULL argument.
6084 (bpstat_clear_actions): Avoid useless call to
6085 breakpoint_auto_delete.
6086 (delete_breakpoint): Clean up bpstat's that are pointing to
6087 the deleted breakpoint from the stop_bpstat chain.
6088 (breakpoint_auto_delete): Simplify.
6089
6090 * Clean up handling of EOF, error on stdin, etc. This was
6091 prompted by a network problem that caused gdb to go into an
6092 infinite loop filling up its malloc'd memory.
6093
6094 main.c (return_to_top_level): Cleanup: call bpstat_clear_actions,
6095 not clear_breakpoints_commands, which is now gone.
6096 (main): If command_loop returns (e.g. from EOF on stdin), do
6097 a quit_command (looping back to command_loop if quit_command
6098 doesn't really quit).
6099 (command_loop): check result from command_line_input and
6100 exit if it returns NULL, rather than passing the NULL to
6101 execute_command.
6102 (gdb_readline): Free malloc'd result space before returning
6103 NULL for EOF.
6104
6105 * utils.c (query): Handle C-d to mean "yes", just as if the
6106 input was not a terminal. Also avoid infinite loop if EOF
6107 occurs in mid-input-line before newline. This allows
6108 query to be used at EOF on stdin with reasonable results.
6109
6110 * infrun.c (proceed): Set breakpoint_proceeded.
6111
6112 * values.c (value_as_long): Avoid infinite recursion for enums.
6113 (_initialize_values): Fix typo in help msg (kingdon).
6114
6115 * Makefile.dist (RL_LIB): Use RL_LIB_DEP for dependencies,
6116 RL_LIB for linking. This allows -lreadline for linking
6117 and nothing for dependencies, once readline is a real library.
6118
6119 * config.gdb: Jim Kingdon: give useful error message if the
6120 host or target type is not recognized.
6121
6122 * defs.h (alloca): SPARC <alloca.h> does not declare alloca,
6123 it just defines it. Dumb, but deal with it.
6124
6125 * Jim Kingdon suggests:
6126 in xconfig/sun3os4, CFLAGS should be XM_CFLAGS.
6127
6128 Wed Aug 29 18:03:27 1990 John Gilmore (gnu at cygint)
6129
6130 * Makefile.dist (VERSION): Bump version # to 3.91.2.
6131
6132 * Clean up Bothner's changes.
6133
6134 * blockframe.c (clear_pc_function_cache): New function.
6135 * blockframe.c: remake cache_pc_function_* static.
6136 * dbxread.c (symbol_file_command): remove references to
6137 cache_pc_function_* variables.
6138 * dbxread.c (read_struct_type): Use VOFFSET_STATIC.
6139 * printcmd.c: Avoid kludging a global variable (addressprint)
6140 to avoid printing the address of a string twice. Instead,
6141 pass the format letter 's' down low enough that it can be seen
6142 to avoid this problem.
6143 (print_formatted): Pass format arg to value_print.
6144 (restore_addressprint): Remove function.
6145 (do_examine): Avoid hacking addressprint, cleanups and such.
6146 (print_frame_args): Add a comment to a Bothner change.
6147 * symtab.h: define VOFFSET_STATIC and use it instead of "-1".
6148 * symmisc.c (free_all_symtabs): Call clear_pc_function_cache
6149 to wipe out the values cached in blockframe.c.
6150 * symtab.c (find_method): Add comment saying how big you must
6151 allocate to be "big enough". Per being terse again.
6152 * valprint.c (val_print): Handle format letter "s" to print
6153 strings without addresses. Add comment to vtbl printing code
6154 which casts with wild abandon. Rearrange reference-printing
6155 code so it prints:
6156 @0xaddr: value (print w/addressprint)
6157 value (print w/~addressprint)
6158 @0xaddr (parameter lists w/addressprint)
6159 or nothing (parameter lists w/o addressprint)
6160
6161 Tue Aug 28 10:47:18 1990 John Gilmore (gnu at cygint)
6162
6163 * Merge more changes from Per Bothner:
6164
6165 Gdb's handling of TYPE_CODE_REF was so counter-C++ (and otherwise
6166 annoying) that I tried to improve it. Here are my suggestions.
6167
6168 These patches all attempt to handle TYPE_CODE_REF (as in C++) better.
6169
6170 findvar.c:
6171 Do automatic de-reference when taking the address of a reference.
6172 printcmd.c:
6173 Don't deref_ref when printing parameter lists.
6174 valops.c:
6175 More attempts at treating refernences properly.
6176 valprint.c:
6177 In val_print, if deref_ref==0, don't print dangling " = ".
6178 value.h:
6179 Add COERCE_REF macro, which de-references an REF.
6180
6181 * Merge changes from Per Bothner:
6182
6183 * Fixed (Sony news)-specific configuration problems.
6184 * Fixed other problems with using vanilla pcc and libc (enum problems;
6185 assumption that vsprintf exists).
6186 * Some major speed-ups (finc_pc_partial_function now caches a match;
6187 parsing avoids duplicate symbol_lookup calls).
6188 * Changed handling of baseclasses (no longer use baseclasses field
6189 of struct type, use the first n_baseclasses fields instead).
6190 * Various minor changes/fixes, most C++-related.
6191
6192 blockframe.c:
6193 Cache the most previous match from find_pc_partial_function.
6194 (Save both low and high ends of matching function's pc range.)
6195 This speeds up the loop of infrun.c:wait_for_inferior quite
6196 a bit, and makes step/next commands much zippier.
6197 command.c:
6198 Added an enum->int cast (otherwise, some compilers barf).
6199 dbxread.c:
6200 No longer set baseclass offset to 0, since multiple
6201 inheritance now mostly works.
6202 Added a number of casts, to shut up compiler warnings
6203 (after stabs where made enums, not ints).
6204 When discarding a symbol table (in symbol_file_command),
6205 must clear the cache introduced in blockframe.c.
6206 Don't convert $vtbl_ptr_type to vtbl any more.
6207 Get rid of TYPE_BASECLASEES and baseclass_vec (see also symtab.h).
6208 Mask off sign bit emitted by g++ for virtual table offset.
6209 Set voffset to -1 (not 1) for static member functions.
6210 expread.y:
6211 Changed parsing/lexing of names to avoid doing symbol lookup twice
6212 (once when lexing to determine symbol class, once for real).
6213 Now only call symbol_lookup once. Fields of 'this' win especially big.
6214 printcmd.c:
6215 Subpress printing addr twice in the case of 'x/s addr'.
6216 symtab.c:
6217 lookup_basetype_type is no longer used.
6218 Add find_methods as recursive helper function to decode_line_1.
6219 This allows multiple inheritance to work.
6220 Also, once one or more matches has been found, do not look in
6221 base-classes. (Baseclass methods would be overridden, anyway.)
6222 symtab.h:
6223 Removed baseclasses array in struct type.
6224 Instead of using baseclasses[i], use fields[i-1].
6225 Added virtual_field_bits[i] to indicate if the i'th baseclass is virtual.
6226 Changed sign convention of voffset (previous was inconsistent).
6227 tm-news.h:
6228 Some macros (CALL_DUMMY and relatives) were missing. Put them back.
6229 utils.c:
6230 Used to assume existence of vsprintf. Re-written to not need it
6231 if HAVE_VPRINTF is undefined.
6232 valops.c:
6233 typecmp was too pessimistic. Made it less so.
6234 valprint.c:
6235 Don't print space after address.
6236 If vtable points to a misc symbol (with 0 offset), print it,
6237 since that indicates the actual class of the object.
6238 Changed ype_print_derivation_info to use new inheritance
6239 scheme (without baseclasses vector).
6240 values.c:
6241 In value_primitive_field, fixed some bugs left over from previous set of fixes.
6242 Also, changes needed because TYPE_BASECLASSES were removed.
6243 xm-news.h:
6244 REGISTER_U_ADDR didn't work for PC. Rewrote to use an array.
6245
6246 Tue Aug 21 20:08:54 1990 John Gilmore (gnu at cygint)
6247
6248 * source.c:
6249 If there is no path set, and the symbols don't indicate what directory
6250 a file was compiled in, look in the current directory. But either
6251 a path or a known compilation directory will prevent this.
6252
6253 * dbxread.c:
6254 Three independent bug fixes:
6255 * Remove the #if 0 block that breaks some stuff.
6256 * SunOS 4.1 fixed the promoted-parameter-wrong-addr bug in Sun C;
6257 adapt gdb to either SunOS 4.0.* or 4.1.
6258 * MAX_OF_TYPE and MIN_OF_TYPE thinko. By tedg@sun, I think.
6259
6260 * symtab.c:
6261 Instantiate the class T when looking for methods in it. (Tiemann@sun)
6262
6263 * valprint.c:
6264 (type_print) Demangle the name being printed.
6265 (type_print_base) Handle botched demangling without coredump (tiemann).
6266
6267 * values.c:
6268 (check_stub_method): Document routine.
6269 (tiemann) fix bug for no-arg functions
6270 Avoid clobbering beyond end of malloc'd storage.
6271 Terminate the argument list properly.
6272
6273 Sat Aug 18 01:29:59 1990 Per Bothner (bothner@cs.wisc.edu)
6274
6275 * Changes merged by John Gilmore:
6276
6277 breakpoint.c:
6278 In breakpoint_1, use new print_address_symbolic instead
6279 of find_pc_partial_function. (This forces use of assembler-level
6280 addresses, and avoids misleading non-mangled source-level names.)
6281 cplus-dem.c:
6282 Generalize ansi argument such that -1 means skip arglist totally.
6283 Removed global variable print_ansi_qualifiers (which made
6284 code non-reentrant), in favor of extra explicit arguments
6285 to internal routines.
6286 printcmd.c:
6287 Add new helper function print_address_symbolic.
6288 Use find_pc_misc_function instead of find_pc_partial_function
6289 (since we want assembler-level symbols here).
6290 stack.c:
6291 Print unknown function as just "f (...)", not "f (...) (...)".
6292 Use new fputs_demangled explicitly.
6293 symtab.c:
6294 Fixed a typing violation (problem: value.h cannot be imported
6295 without renaming many variable in this file).
6296 lookup_symbol: If no matching misc_func, look for a C++-mangled name.
6297 decode_line_1: Moved forward some never-reached code.
6298 Made decode_line_2 skip function prologues correctly.
6299 utils.c:
6300 fputs_filtered should not demangle by default.
6301 Add new fputs_demangled to demangle on demand..
6302 valops.c:
6303 Change value_struct_elt to use value_primitive_field (using recursive
6304 utility function search_struct_field). This allows foo.bar to work
6305 for multiple inheritance (so far only for data fields).
6306 Change check_field in the same way (recursive helper function
6307 to support multiple inheritance).
6308 (Note: there are more of these problems that I haven't fixed.
6309 Any code that says TYPE_BASECLASS (t, 1) is probably wrong.)
6310 value_of_this: 'this' symbol name is now just "this", note "$this".
6311 valprint.c:
6312 Don't print static members.
6313 Avoid printing "members of <type>" if there are none.
6314 Simplified type_print_derivation_info by merging duplicate code.
6315 Remove useless blank lines in type_print_base (ptype command).
6316 value.h:
6317 Added declaration of new routine value_primitive_field.
6318 values.c:
6319 Added value_primitive_field which is generalized version of
6320 value_field that can handle multiple inheritance (non-zero offsets etc).
6321 Re-implemented value_field to call value_primitive_field.
6322
6323 Fri Aug 17 23:33:44 1990 John Gilmore (gnu at cygint)
6324
6325 * infcmd.c -- insert else to avoid 'delete env' coredump when you
6326 delete the whole environment. Karl Berry reported the bug.
6327 * source.c - fix openp to avoid //'s in filenames, which
6328 trigger an Emacs bug causing it to not be able to find files
6329 when running gdb in a window.
6330 * dbxread.c - zap the #if 0 that botches the add-file code.
6331 It seems to work a lot better without all the code commented out.
6332
6333 Fri Jul 20 16:58:46 1990 John Gilmore (gnu at cygnus.com)
6334
6335 * Merge Tiemann's and Ted Goldstein's changes, detailed below,
6336 into gdb-3.90.9.
6337
6338 Tue Jul 17 19:34:33 1990 Ted Goldstein (tedg at golem)
6339
6340 * Makefile - added a ${CFLAGS} to a couple of entries,
6341 added remote-sa.sparc.c
6342 * added remote.sa-sparc.c, a modification of remote.c
6343 which conducts a dialog directly with the SparcStation prom.
6344 * breakpoint.c, infrun.c, sparcdep.c added
6345 remote_insert_breakpoint(), and remote_remove_breakpoint()
6346 to breakpoint.c instead of directly writing breakpoint instructions.
6347 * sparcdep.c on remote_debugging,there is no need
6348 to remove signle step breakpoint instructions.
6349 * main.c added "-epoch" flag and "int epoch_interface" to main.c
6350 global variable
6351 * printcmd.c - epoch interface sends lisp expressions to open up
6352 epoch windows on inspection.
6353 * valprint.c - added arrayprint, and addressprint and made adding
6354 format controls easier
6355 * wait.h added a couple of undef's because we were getting
6356 complaints about WSTOPSIG and WTERMSIG begin redefined.
6357
6358
6359 Wed Jul 4 05:27:51 1990 Michael Tiemann (tiemann at masham)
6360
6361 * symtab.c (decode_line_1): Add support for handling method stubs
6362 in the type information.
6363
6364 Tue Jul 3 09:39:18 1990 Michael Tiemann (tiemann at masham)
6365
6366 * values.c (baseclass_addr): Run loop from INDEX+1 to
6367 N_BASECLASSES; otherwise, we can still get into a loop.
6368 @@ This should be restructured to use a cleaner search strategy.
6369
6370 Sun Jul 1 12:28:51 1990 Michael Tiemann (tiemann at masham)
6371
6372 * dbxread.c (define_symbol,read_type): Grok GNU C++'s new
6373 abbreviation "Tt" for tags which have the same name as their
6374 typedecls.
6375
6376 Fri Jun 29 01:03:46 1990 Michael Tiemann (tiemann at masham)
6377
6378 * symtab.c (list_symbols): add ability to set breakpoints on all
6379 the functions which match a particular regular expression.
6380
6381 Tue Jun 26 04:26:29 1990 Michael Tiemann (tiemann at masham)
6382
6383 * cplus-dem.c (cplus_demangle): New parameter ANSI says whether we
6384 should print ANSI qualifiers (such as `const' and `volatile').
6385 All callers changed to call with ANSI == 1, except from
6386 `check_method_stub', which uses old-style syntax.
6387
6388 * symseg.h (struct fn_field): Remove unneccessary `args' field.
6389 * symtab.h (TYPE_FN_FIELD_ARGS): Redefined.
6390
6391 * values.c (check_stub_method): New function.
6392
6393 * cplus-dem.c (do_type): Handle "long long" (encoded as 'x').
6394
6395 * dbxread.c (read_type): Handle new GNU C++ method type stubs.
6396 * valprint (type_print_base): Ditto.
6397
6398 * symtab.c (gdb_mangle_typename): New function.
6399
6400 Tue Jun 5 00:18:43 1990 Michael Tiemann (tiemann at gzilla)
6401
6402 * breakpoint.c (catch_command): New function. Provides a
6403 mechanism to set breakpoints based on catch clauses.
6404 (disable_catch): Similar, but disables breakpoints on catch
6405 clauses.
6406 (delete_catch): Similar, but deleted breakpoints on catch clauses.
6407
6408 Sun Jun 3 22:54:08 1990 Michael Tiemann (tiemann at gzilla)
6409
6410 * blockframe.c (blockvector_for_pc): New function.
6411 * blockframe.c (block_for_pc): Changed to call
6412 `blockvector_for_pc' and get the block itself.
6413
6414 * stack.c (catch_info): New function. Prints info about
6415 exceptions which can be caught in the current frame.
6416 * stack.c (print_frame_label_vars): New function. Similar to
6417 `print_frame_local_vars'.
6418 * stack.c (print_block_frame_labels): Prints out labels that are
6419 defined in this frame. These labels are exceptions that can be
6420 caught.
6421
6422 * dbxread.c: Updated to handle N_CATCH symtab types.
6423
6424 Thu May 3 22:10:00 1990 Michael Tiemann (tiemann at teacake)
6425
6426 * valprint.c (everywhere): TYPE_NAME (TYPE) no longer comes in the
6427 form "struct ..." for GNU C++. Don't flush any part of TYPE_NAME
6428 when printing the type.
6429
6430 Wed May 2 22:43:04 1990 Michael Tiemann (tiemann at teacake)
6431
6432 * valprint.c (val_print): Use `baseclass_addr' to access the
6433 baseclasses pointed to via the derived class object at VALADDR.
6434
6435 * values.c (baseclass_addr): New function. Casts derived pointers
6436 to baseclass pointers taking virtual baseclasses and multiple
6437 inheritance into account.
6438
6439 Sat May 5 12:39:18 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
6440
6441 * Version 3.90.9.
6442
6443 Fri May 4 12:12:55 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
6444
6445 * breakpoint.c (watch_command, bpstat_stop_status): Deal with
6446 exp_valid_block field correctly.
6447
6448 * infrun.c (wait_for_inferior): When checking "don't even think
6449 about breakpoints" if stop_signal == SIGTRAP && trap_expected,
6450 also check step_resume_breakpoint.
6451 Insert breakpoints and continue (not step) if
6452 step_resume_break_address != NULL, even if another_trap.
6453 If trap_expected and we enter sigtramp, then set up a
6454 step_resume_break.
6455 If trap_expected is set when we hit the step_resume_break,
6456 set another_trap.
6457 When calling resume and trap_expected says tell resume to step
6458 (2 places), also check step_resume_break_address.
6459
6460 * infrun.c (wait_for_inferior): Don't set
6461 prev_{pc,sp,func_{start,name}} before calling wait ().
6462 Do set them after exiting loop.
6463 Move their declarations outside functions.
6464 (start_inferior): Initialize them.
6465
6466 Thu May 3 00:15:11 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
6467
6468 * infrun.c (wait_for_inferior, after check for trap_expected > 1):
6469 Restore old code which distinguishes between trap_expected and
6470 running_in_shell, just make the latter take any non-TRAP signal,
6471 not just SEGV.
6472
6473 * values.c (allocate_value): Zero VALUE_OPTIMIZED_OUT flag.
6474
6475 * Makefile.dist (pinsn.o): Use PINSN_CC to compile.
6476 xconfig/3b1 (CC,PINSN_CC): Define.
6477
6478 * xconfig/altos, altos-dep.c: Rename altos-dep.c to altos-xdep.c.
6479
6480 * Version 3.90.8
6481
6482 * breakpoint.c (bpstat_stop_status),
6483 infrun.c (wait_for_inferior) [SHIFT_INST_REGS]: New code.
6484
6485 * param.h, tm-88k.h: Define ADDR_BITS_*.
6486 infcmd.c (jump_command, read_pc), infrun.c (wait_for_inferior),
6487 printcmd.c (do_one_display): Use them.
6488
6489 * utils.c: Split #ifdef USG into a USG_UTILS and a QUEUE_MISSING.
6490 xm-88k.h: Define USG_UTILS.
6491
6492 Wed May 2 00:05:33 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
6493
6494 * printcmd.c (printf_command) [__INT_VARARGS_H]: New code.
6495 (printf_command): Add from_tty parameter.
6496
6497 * valprint.c (value_print): Check VALUE_OPTIMIZED_OUT flag.
6498
6499 * value.h: Add optimized_out field and change lazy field to
6500 char. Add macro VALUE_OPTIMIZED_OUT.
6501
6502 * i386-pinsn.c: Change from Eirik Fuller to write to stream directly
6503 instead of stuffing things in buffers (oappend, etc).
6504
6505 * breakpoint.c (bpstat_do_actions): If *BSP is set to NULL by
6506 execute_command, exit both loops.
6507
6508 * Makefile.dist: Don't set TARGET_ARCH. Add .c.o rule.
6509
6510 Tue May 1 17:07:23 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
6511
6512 * Makefile.dist (RAPP_OBS, rapp),
6513 rgdb.c, rserial.c, rudp.c, serial.c, udp.c, xdep.h,
6514 remote.h: Added.
6515 m68k-xdep.c, coredep.c: Wrap in #if !defined (RDB).
6516
6517 * valops.c (value_struct_elt), values.c (value_static_field):
