3 * doc/gdb.texinfo: remove leading comments that survived M4 but
4 described its role in the doc; add one more font to colophon;
5 strengthen disclaimer about unsupported configs.
7 Wed Nov 27 01:23:41 1991 John Gilmore (gnu at cygnus.com)
9 Fix bugs in C++ debugging.
11 * symtab.h: target_type is not used in record types.
12 Eliminate TYPE_MAIN_VARIANT and TYPE_NEXT_VARIANT. Eliminate
13 lookup_method_type. Add TYPE_TYPE_SPECIFIC macro.
15 * symtab.c (lookup_member_type): Don't chain them up, just
16 allocate one in symbol_obstack when we need one.
17 (allocate_stub_method): Build stub in symbol_obstack.
18 (check_stub_method): Move here from values.c. Don't deallocate
20 (lookup_method_type): Gone now.
22 * buildsym.c: Handle g++ v1 stabs a little bit better.
23 Change some C++ parsing error()s to complain()ts.
24 * buildsym.c, findvar.c, printcmd.c, symtab.c: Make unions and
25 structs have the same representation and work the same as far as
27 * buildsym.c, symtab.c, values.c: Remove all references to
28 TYPE_MAIN_VARIANT and TYPE_NEXT_VARIANT.
30 * valops.c: Improve comments and indentation. Only call
31 check_stub_method when the stub flag is on.
32 * valprint.c: Fix or mark minor bugs and unportabilities.
34 * coffread.c (anonymous unions): Allocate a cplus structure.
36 * mipsread.c: Eliminate "template" types. Build new, real
37 types whenever we need them. Allocate cplus structures as needed.
38 Bulletproof the type parsing a bit more. Mark storage leaks.
39 (parse_type): Copy TYPE_TYPE_SPECIFIC when copying a real type
40 on top of a partial type.
42 Fri Nov 22 16:39:57 1991 John Gilmore (gnu at cygnus.com)
44 * inflow.c (terminal_inferior): Check the results of ioctl's, and
45 print a message if any of them fail.
46 (terminal_ours_1): Store result of ioctl's for debugging, but
47 don't print (the terminal isn't ours...).
49 * tm-tahoe.h (FRAME_ARGS_ADDRESS): No need to offset from frame
52 * m2-exp.y (MAX, MIN): Rename to MAX_FUNC, MIN_FUNC to avoid
53 conflicts with system header files.
55 Fri Nov 22 08:27:40 1991 John Gilmore (gnu at cygnus.com)
57 * Roll VERSION to 4.2.95.
59 * buildsym.c, coredep.c, mem-break.c, xcoffread.c: Put <stdio.h>
61 * config/mh-i386sco: Override compiler to gcc, print warning.
62 * configure.in: Handle i386-none-aout rather than i386-aout-none.
63 * infptrace.c, language.h, utils.c: Lint.
64 * m2-exp.y: #undef MAX and MIN in case system includes set them.
65 * xm-tahoe.h: Set HOST_BYTE_ORDER. Include system versions of
66 {BIG,LITTLE}_ENDIAN and the INT_MAX family first, to avoid
67 redefinition warnings.
68 * defs.h: Reorder things so that the xm-file gets first crack
69 at #define's, followed by defs.h and then the tm-file.
70 * Makefile.in: Remove spaces after 'ignore exit code' - flags.
71 Late-model BSD 'make's don't cope with them.
73 Thu Nov 21 23:48:56 1991 John Gilmore (gnu at cygnus.com)
75 * Makefile.in: Roll new files into various lists.
77 Thu Nov 21 18:26:11 1991 Fred Fish (fnf at cygnus.com)
79 * dwarfread.c (struct_type): Must initialize the c++ specific
80 portion of union types as well as struct types, since gdb attempts
81 to reference the c++ specific info for both types.

105 * xcoffexec.c: Add /* */ to #if 0'd thing to help ANSI.
107 Wed Nov 20 18:35:56 1991 John Gilmore (gnu at cygnus.com)
109 * Remove gdb/hp-include. Support for HP a.out oddities should be
110 in BFD, not in GDB. Move gdb/hp-include/a.out.h to include/a.out.hp.h.
112 * infptrace.c, tm-sun386.h: Cashier <a.out.gnu.h>, remove refs.
114 * configure.in, xconfig, tconfig, Makefile.in, doc/gdbint.texinfo:
115 Makefile fragments for various hosts and targets now come from
116 gdb/config/mh-* and gdb/config/mt-*. This is for consistency with
119 * rs6000-pinsn.c, rs6k-opcode.h: Clean up.
120 * rs6k-opcode.def: Delete.
122 Wed Nov 20 05:04:40 1991 Fred Fish (fnf at cygnus.com)
124 * dwarfread.c: Recognize obsolete form of AT_element_list
125 attribute still used by at least one AT&T compiler, and possibly
128 Tue Nov 19 07:53:55 1991 Fred Fish (fnf at cygnus.com)
130 * dwarfread.c (enum_type, struct_type): Ignore names invented by
131 helpful compilers for anonymous structs, unions, and enums.
133 * c-exp.y, m2-exp.y: Add defines for yymaxdepth, yy_yys, and
134 yy_yyv, so multiple parsers produced by SVR4 versions of yacc
135 can coexist in the same executable without collision.
137 * symtab.h: Add declaration for lookup_template_type() to kill
138 compiler warnings about conversions from int to pointer.
140 Mon Nov 18 17:45:18 1991 Fred Fish (fnf at cygnus.com)
142 * procfs.c: Move inclusion of defs.h to before param.h, as in
143 all the other source files that include both. This is required
144 to supply some typedefs that are used in files included by param.h.
146 * m68k-tdep.c (m68k_skip_prologue): Add generic m68k support for
147 skipping function prologues, ala the other cpu families (i386,
148 mips, m88k, etc). Add the ability to skip movm and fmovm
149 instructions in the prologues. Still needs support for profile
150 (-p compiled) prologue sequences (FIXME).
152 * tm-68k.h: Change SKIP_PROLOGUE macro to use the new generic
153 m68k prologue skipping function by default.
155 * tm-altos.h, tm-isi.h: Continue to use the old definition of
158 Mon Nov 18 15:12:45 1991 John Gilmore (gnu at cygnus.com)
160 * Makefile.in: Remove tdesc stuff, and extra blanks before colons.
161 * blockframe.c: Remove tdesc-related code. Default
163 * infrun.c: Remove tdesc-related code.
164 * m88k-tdep.c (frame_chain_combine, init_frame_pc): Remove copies
165 of defaultable things.
166 * tm-m88k.h: New file, common to all Moto 88k target configs.
167 Derived from tm-delta88.h.
168 * tm-delta88.h: Use it.
169 * xm-m88k.h: Common file for 88K hosts. Remove obsolete stuff.

171 * tm-*.h: Remove FRAME_CHAIN_COMBINE macros, since all are
173 * coffread.c: Remove tdesc stuff.
174 * tconfig/delta88, tconfig/m88k: Remove tdesc stuff.
175 * xconfig/m88k: Rename tm-88k.h to tm-m88k.h.
177 Mon Nov 18 13:51:37 1991 Per Bothner (bothner at cygnus.com)
179 * source.c (open_source_file): If openp fails, try again
180 using just the base (non-directory) part of the filename.
181 This solves various annoying problems, such as when the
182 source was compiled with an absolute pathname - and the
183 source files have moved. Or if the source was compiled
184 using a relative pathname, it can be more convenient
185 to just specific the source directory to the dir command.
187 Mon Nov 18 00:04:41 1991 Fred Fish (fnf at cygnus.com)
189 * cplus-dem.c (munge_function_name): Add missing third arg to
190 instance of call to do_type().
192 * dwarfread.c: Changes to match new dwarf.h. Remove
193 AT_deriv_list, AT_loclist, AT_incomplete, AT_const_data,
196 Sun Nov 17 16:20:53 1991 Michael Tiemann (tiemann at rtl.cygnus.com)
198 * symtab.h (struct type): Moved C++-specific fields into new type
199 `struct cplus_struct_type'. Now takes 10% less memory. Many
201 * symtab.c (init_type): Don't set fields belonging to
202 TYPE_CPLUS_SPECIFIC unless TYPE is TYPE_CODE_STRUCT.
203 * buildsym.c (read_type): Allocate TYPE_CPLUS_SPECIFIC for
205 (read_struct_type): Ditto. Also, add comments about how we can
206 deduce TYPE_VPTR_FIELDNO from inheritance info and fieldname info.
207 * coffread.c (decode_base_type): Allocate TYPE_CPLUS_SPECIFIC for
209 (read_struct_type): Ditto.
210 * dwarfread.c (struct_type): Ditto.

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

263 Motorola 88000 port without tears, I mean without tdescs.
265 * m88k-tdep.c: Blow away all tdesc stuff.
266 Provide functions for all the frame-related macros in
267 tm-delta88.h. Adopt i960-style EXTRA_FRAME_INFO.
268 (examine_prologue, frame_find_saved_regs, skip_prologue): borrow
269 from i960-tdep.c and adapt to the function prologues on the 88k.
270 (read_next_frame_reg): Borrow from mips-tdep.c.
271 FIXME: frame_locals_address should go away.
273 * tm-delta88.h: Dump all the tdesc stuff.
274 Macros for all frame-related stuff call fns of same name.
275 Remove duplicated definitions. FP_REGNUM becomes same as
278 * xm-88k.h: Eliminate lots of library dependencies, now handled
279 in libiberty. Eliminate KDB nonsupport.
281 * doc/gdbint.texinfo: Add rudiments on frames. FIXME, add more.
284 * stack.c (frame_info): Mark frameless functions.
285 Print locals address (FIXME, remove if same).

305 * symtab.c (decode_line_1): For example (see above), here.
306 * buildsym.c, symtab.h: Remove TYPE_FLAGS_HAS{CON,DE}STRUCTOR
307 flags since they are no longer used.
309 Fixes to support C++ methods with functional parameters.
310 * c-exp.y (func_mod rule): Allow (and ignore) list of parameter
311 types in a function type.
312 * eval.c (parse_and_eval_type), value.h: New function,
313 parse_and_eval_type, is based on old code from check_stub_method.
314 But don't actually evaluate the cast, since that calls
315 value_cast(), whcih may fail. Just extract the type
316 from the parsed expression.
317 * values.c (check_stub_method): While looping through the
318 arguments, adjust depth *after* parameter has been handled.
319 Replace call and setup of parse_and_eval with new function
322 Tue Nov 12 09:40:07 1991 Fred Fish (fnf at cygnus.com)
324 * utils.c, rem-multi.shar: Remove fixed arg count version of

329 m88k-xdep.c, main.c, printcmd.c, pyr-xdep.c, source.c,
330 sun386-xdep.c, symm-xdep.c, umax-xdep.c, values.c, xcoffread.c:
331 Change all instances of use of fixed args concat() to variable
332 args concat() now located in libiberty.

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

358 * dwarfread.c (dwarf_psymtab_to_symtab): Remove leftover call
359 to do_cleanups() which resulted from a previous change.
361 * elfread.c: Re-enable compilation of register_addr() stub
362 whenever it is not supplied by coredep.c
364 Sat Nov 9 00:40:32 1991 John Gilmore (gnu at cygnus.com)
366 Add tracking of object files (that contain symbols) to gdb.
367 This includes a "struct objfile" that owns symtabs and psymtabs
368 that were read in from that binary file.
370 * symfile.h: Add struct objfile. Add pointer to the objfile
371 into the struct sym_fns.
372 Replace global `symfile' and `symfile_mtime' with
373 `symfile_objfile'. Add global object_files chain.
375 * symfile.c: Move param.h above symtab.h.
376 (sort_misc_function_vector): Add.
377 (syms_from_objfile): Was syms_from_bfd.

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

432 (struct symtab): Add objfile * and objfile_chain * of symtabs.
433 (struct partial_symtab): Add objfile * and objfile_chain * of
434 psymtabs. Remove symfile_name.

443 * symfile.h, symfile.c, symtab.h: Lint
445 Fri Nov 8 23:38:48 1991 John Gilmore (gnu at cygnus.com)
447 * command.c: Include param.h.
448 * defs.h (warning_setup, warning): Declare.

454 Thu Nov 7 18:26:15 1991 Steve Chamberlain (sac at rtl.cygnus.com)
456 * Makefile.in: link with libiberty after libreadline, since
457 readline might want something in libiberty.
458 * m88k-xdep.c: Fixed the register offsets in the ptrace_user
459 struct for BCS 88k machines.
460 * xm-m88k.h: don't define USIZE if already defined.
461 * configure.in: Added delta88 target.
463 Thu Nov 7 04:51:19 1991 John Gilmore (gnu at cygnus.com)
465 * am29k-pinsn.c, am29k-opcode.h: Fix decoding of mtacc, dmac, fmac.
467 * tm-*.h: Remove READ_DBX_FORMAT, COFF_FORMAT, and
468 READ_MIPS_FORMAT, which have been unused since BFD. Still
469 remaining is COFF_NO_LONG_FILE_NAMES.
470 * tm-sun3.h, tm-altos.h: Remove detritus accidentally left from
471 function calling code moved to m68k-tdep.c.
473 Wed Nov 6 17:21:59 1991 John Gilmore (gnu at cygnus.com)
475 * coffread.c: Eliminate c_nsyms in favor of c_naux.
476 Complain if no auxents on .bf and .ef FCN symbols, and assume
477 lots of line numbers.
478 (init_linenos, enter_linenos): Use a sentinel at the end of the
479 read-in linenos, to make for a fast, safe loop-end test.
481 Wed Nov 6 02:54:08 1991 Steve Chamberlain (sac at cygnus.com)
483 * coffread.c (read_coff_symtab): coffread used to rely on the
484 x_sym.x_misc.x_lnsz.x_lnno field giving the # of linnos in a
485 function. Two of the formats I'm using (29k and 88k) don't seem to
486 set it. Ths patch to fcn_last_line and (enter_linenos) is an
487 attempt to use the actual size of the linno table in the file to set
488 the number of linenos to process.
490 Tue Nov 5 22:47:46 1991 Steve Chamberlain (sac at cygnus.com)
492 * Makefile.in: put a - infront of the mv y.tab.c c-exp.tab.c and
493 mv y.tab.c m2-exp.tab.c, so that if bison is used, and the files
494 are created in place, so the mv fails, then the make continues.
496 Tue Nov 5 16:47:47 1991 Per Bothner (bothner at cygnus.com)
498 Add C++ as a separate language.
499 * defs.h (enum language): Add language_cplus.
500 * dwarfread.c (end_symtab): Support language_cplus.
501 * c-exp.y: Add new struct language_defn cplus_language_defn.
502 Don't set c to be the default language (see main.c).
503 * c-exp.y (yylex): Only look for field of this if
504 language is C++. (First difference from C!)
505 * language.c: Add case branches for C++ (currently, all
506 the same as C). Also, add c++ to "usage" note for "set lang".
507 * valprint.c (typedef_print). Add case branches for C++.
508 * main.c (main): New way to set initial language: Look at
509 file extension of psymtab containing main(). (Same as we
510 do for symtabs, but avoid loading the symtab yet.)
511 * symtab.c: New routine find_main_psymtab(), used by main()
512 to set initial language.
513 * symfile.c (allocate_symtab): Move code for mapping file
514 extensions-> languages to new deduce_language_from_filename().
516 Fix a C++ problem when looking for methods in super-classes.
517 There was confusion between base and derived types.
518 * valops.c (value_fn_field): Change function interface.
519 * values.c: Use new value_fn_field interface.
521 Mon Nov 4 10:49:33 1991 Per Bothner (bothner at cygnus.com)
523 * infrun.c: Fixed typo in comment.
524 * utils.c: All the v*fprintf emulation is now in libiberty,
525 so we can get rid of some junk.
526 * xm-sun3os4.h, xm-sun4os4.h, xconfig/decstation, xconfig/i386sco,
527 xconfig/sun3os4, xconfig/sun4os4: Don`t need HAVE_STRSTR any more.
528 * m68k-pinsn.c (print_insn_arg): Support BB/BW/BL
529 type operands, as used by branch instructions.
530 * gmalloc.c: Fix prototype of memcpy.
531 * elfread.c: Comment out register_addr, since it conflicts
532 with the one in coredep.c.
533 * buildsym.h: Remove extern declarations of two functions
534 that are really static in buildsym.c.
535 * tm-mips.h: Add symbolic names for more registers.
536 * mips-xdep.c (store_inferior_registers): Use new register names.
537 * xm-mips.h: Simplify REGISTER_U_ADDR, since it is now
538 only used for core files, not ptrace. Therefore,
539 the KERNEL_U_ADDR hack is no longer needed.
540 The mapping to ptrace number is now in in mips-xdep.c.
541 * mips-xdep.c: Define REGISTER_PTRACE_ADDR (using the
542 mapping from the old REGISTER_U_ADDR), and use it
543 in {fetch,store}_inferior_registers.
544 * mipsread.c: Rename #include ecoff.h to new name coff-mips.h.
545 * mips-tdep.c (mips_push_dummy_frame, mips_pop_frame):
546 Save/restore FP regs correctly (?).
547 * dbxread.c: Remove duplicate define_symbol and type_synonym_name
548 (these had been previously moved to buildsym.c).
549 Hence, define_symbol becomes extern instead of static.
550 * buildsym.c (read_struct_type): Comment out bogus handling
551 of C++ operator methods. Minor hacking of reading of class
552 contexts. Make define_symbol non-static, so dbxread.c can call it.
554 Fri Nov 1 11:05:47 1991 John Gilmore (gnu at cygnus.com)
556 * mipsread.c (read_mips_symtab, read_the_mips_symtab): Use real
557 filename with error messages.
558 * stack.c (frame_select_command): Rename to select_frame_command
559 to avoid "fr" and "fra" having nonunique completions.
560 * symfile.c (sort_symtab_syms): Ignore sort of zero symtab *.
561 (symfile_init): Print file format name when unable to handle it.
562 (free_named_symtabs): Use BLOCKVECTOR rather than obsolete BLOCKLIST.
563 * symmisc.c (free_symtab): Only free linetable if nonzero.
564 * symtab.h: Remove obsolete BLOCKLIST macros.
566 Thu Oct 31 18:12:43 1991 Stu Grossman (grossman at cygnus.com)
568 * infrun.c (wait_for_inferior): another stepi/nexti fix. Ensure
569 that stop_step is 1 at bottom of main loop. I don't know why this
570 needs to be done, but it helps me sleep better at night.
572 Sun Oct 27 18:18:39 1991 Stu Grossman (grossman at cygnus.com)
574 * main.c (initialize_history): Read history after reading all
577 Sun Oct 27 14:09:25 1991 John Gilmore (gnu at cygnus.com)
579 * buildsym.c: Break out initial malloc sizes.
580 (record_line): Record directly in a subfile. Alloc on demand.
581 (compare_line_numbers): Add from xcoffread.c.
582 (end_symtab): New params say whether to sort pendings and
583 linetable. Patch block stabs if defined. Shrink linetable before
584 allocating the symtab.
585 * buildsym.h: Delete line_vector* and prev_line_number. Add
586 global_stabs and file_stabs for xcoffread.
587 * dbxread.c (start_subfile): Move to buildsym. Change above calls.
588 * symtab.h: LINETABLE(symtab) can now be null. Zap LINELIST.
589 * symmisc.c, symtab.c: Cope with null LINETABLEs.
591 * blockframe.c: Pass fromleaf to INIT_EXTRA_FRAME_INFO.
592 * tm-29k.h, tm-88k.h, tm-i960.h, tm-irix3.h, tm-mips.h, tm-pyr.h,
593 tm-sparc.h: Accept fromleaf parameter.
594 * c-exp.y (yyerror): Pass error message if given.
595 * configure.in: Add rs6000 host and target.
596 * inflow.c (new_tty): O_NOCTTY kludge for RS/6000.
597 * symfile.h (entry_point): Add.
599 Sat Oct 26 00:16:32 1991 John Gilmore (gnu at cygus.com)
601 * buildsym.c: New file. Breaks out symbol-table-building routines
602 from dbxread.c, so they can be shared with xcoffread.c.
603 * buildsym.h: New file. Declarations for buildsym.c users.
604 * dbxread.c: Remove large chunks into buildsym.c.
605 * Makefile.in: Add buildsym.c and buildsym.h.
607 * symfile.c (syms_from_bfd): New routine.
608 (add_symbol_file): Call it to do the real work.
609 (syms_from_bfd): Initialize entry_point before calling symfile_init.
610 * symtab.h, symfile.c, coffread.c, mipsread.c, dwarfread.c:
611 Avoid declaring or setting entry_point (symfile.h & symfile.c cope).
613 Fri Oct 25 10:58:16 1991 Mark Eichin (eichin at cygnus.com)
615 * cplus-dem.c (cplus-demangle): added support for templates, static
616 data, and the new (correct) mangling for destructors.
618 * dwarfread.c: (dwarfwarn): created a varargs version of
619 dwarfwarn, for non __STDC__ compilers.
621 * c-exp.y: (yylex): added match for "template" token.
622 (typebase): added TEMPLATE name '<' type '>' clause, for explicit
623 specification of template types.
625 * symtab.c: (lookup_template_type): new function for finding
626 templates in symbol table.
627 (type_name_no_tag): changed to explicitly check for s/u/e at the
628 beginning of the symbol - if it is a template, none of these will
629 be there (but the name will still contain spaces.)
631 Fri Oct 25 18:59:32 1991 Per Bothner (bothner at cygnus.com)
633 Various fixes to improve g++ debugging.
634 * symtab.h: Add is_const and is_volatile flags for each method.
635 These are bit fields - take their space from voffset,
636 which shrinks to 30 bits. Since voffset is now a bitfield,
637 make it unsigned for portability. This changes its interpretation
638 slightly: Static methods now have voffset 1 instead of -1,
639 and virtual offsets start at 2, not 1.
640 * symtab.c: Renamed gdb_mangle_typename to gdb_mangle_name,
641 since it now returns an entire magled method name, not just
642 the type part. This avoids some duplication.
643 It also allows us to correctly mangle const and volatile
644 methods (using the new is_const and is_volatile bit fields
646 * valprint.c (type_print_base), values.c (check_stub_method):
647 Simplify by using new gdb_mangle_name.
648 * values.c (value_headof): Fix to correctly handle single
649 inheritance (actually two fixes, either of which suffices).
650 * dbxread.c (read_struct_type): Handle const and volatile
652 * dbxread.c (read_struct_type): Yet one more place where
653 we must handle '\\' continuations.
654 * valprint.c (vtbl_ptr_name): Add final '\0'.
656 Fri Oct 25 16:06:38 1991 Stu Grossman (grossman at cygnus.com)
658 * tm-sparc.h, tm-68k.h (EXTRACT_RETURN_VALUE): fix output of
659 short return values for sparc and 68k. Patch from Paul Eggert.
661 * coffread.c, coredep.c, i386-xdep.c: install patches for
662 SysV/386 3.2 from Mauro DePalma.
664 Fri Oct 25 02:02:13 1991 John Gilmore (gnu at cygnus.com)
666 * core.c (core_file_info), exec.c (exec_file_info): Print file
667 type. Use printf_filtered.
669 * valops.c (value_fetch_lazy): Avoid 0-length fetches.
671 Thu Oct 24 23:06:40 1991 Fred Fish (fnf at cygnus.com)
673 * dwarfread.c: Add casts to remove compiler warnings.
675 * tm-3b1.h, tm-68k.h, tm-altos.h, tm-amix.h, tm-hp300bsd.h,
676 tm-hp300hpux.h, tm-isi.h, tm-news.h, tm-pn.h, tm-sun2.h,
677 tm-sun3.h: Remove locally duplicated code for calling functions
678 in the inferior. The only differences were in the specific trap
679 vectors used and whether or not an fpu was present. These are
680 now handled by appropriate definitions of BPT_VECTOR and
681 HAVE_68881 respectively. Other minor obvious cleanups.
683 * valops.c: Correct a minor misspelling.
685 * utils.c: Remove local BSD/USG hacks that are now in libiberty.
687 * dwarfread.c: Remove prototype for dwarfwarn. Does not work
690 Thu Oct 24 09:33:44 1991 John Gilmore (gnu at cygnus.com)
692 * stack.c (frame_command): Always print. Use new
693 frame_select_command to select a frame without printing.
695 * dwarfread.c: Use <varargs.h>, since <stdarg.h> is not portable.
697 Thu Oct 24 01:32:51 1991 Fred Fish (fnf at cygnus.com)
699 * dwarfread.c: New file for DWARF debugging format support.
701 * elfread.c: New file for ELF object file format support.
703 * procfs.c: New file for SVR4 /proc (process file system) support.
705 * tm-amix.h, xm-amix.h, tconfig/amix, xconfig/amix: New files for
708 * xm-svr4.h, tm-svr4.h: New files for SVR4 support.
710 * xm-m68k.h: New file for host machines with m68k cpu.
712 * Makefile.in: Add elfread.c and dwarfread.c to SFILES_MAINDIR.
713 Add elfread.o and dwarfread.o to OBS.
715 * symfile.h: Add "elf" to list of supported formats in comment.
717 * c-exp.y, defs.h, symtab.h, valprint.c: Add three new builtin
718 types to gdb, builtin_type_long_double, builtin_type_complex, and
719 builtin_type_double_complex. Add and use new TARGET_SHORT_BIT,
720 TARGET_INT_BIT, TARGET_LONG_BIT, TARGET_FLOAT_BIT,
721 TARGET_DOUBLE_BIT, TARGET_LONG_DOUBLE_BIT, TARGET_COMPLEX_BIT, and
722 TARGET_DOUBLE_COMPLEX_BIT, as the sizes in bits of the indicated
723 types on the target machine (ala the existing TARGET_LONG_LONG_BIT).
725 * infrun.c: When using SVR4 /proc interface instead of ptrace(),
726 call proc_set_exec_trap() to setup child to stop at first instruction.
728 * inftarg.c: When using SVR4 /proc interface, call proc_wait()
731 * m68k-tdep.c: Add new routines supply_gregset(), fill_gregset(),
732 supply_fpregset(), and fill_fpregset(), which are machine
733 dependent support routines for SVR4 /proc interface.
735 * utils.c: Add warning_setup() and warning(). Warning() behaves
736 the same as error() except that it returns normally rather than
737 jumping back to command level. Modules that don't want to call
738 warning() for some reason, but want to produce their own warnings,
739 can call warning_setup() to ensure compatibility with the way
740 warning() and error() deal with the terminal.
742 * symtab.c: Make internal errors produce more useful messages.
744 * tm-68k.h: Move code that is duplicated in almost every single
745 m68k based machine's configuration files to this common file.
746 Duplications in the configuration files still need to be removed
749 * infrun.c (child_create_inferior): System V versions must call
750 setpgrp() with no arguments, to comply with prototyping typically
753 * munch: Add support for SVR4 style nm output.
755 * dbxread.c, mipsread.c symmisc.c, symtab.c: Remove the object
756 file specific fields from the partial symbol table structure and
757 replace them with a pointer to private data for each different
758 flavor of object file reader to initialize appropriately.
760 Wed Oct 23 09:38:20 1991 John Gilmore (gnu at cygnus.com)
762 * xconfig/sun[34]os4: Add note about strstr botch on sunos4.0.3c
765 * mipsread.c (fixup_undef_type): New function. If a struct /
766 union / enum is defined in a header file but nowhere else used,
767 (by typedefing, pointer referencing or declaration) the mipsread code
768 builds the complete tree for the structure but leaves its code as
769 TYPE_CODE_UNDEF as it doesn't know what kind of aggregate it is.
770 Guess its type based on the details of the members.
772 Tue Oct 22 18:04:32 1991 Stu Grossman (grossman at cygnus.com)
774 * infrun.c (wait_for_inferior): Check return value from
777 Mon Oct 21 17:47:03 1991 Stu Grossman (grossman at cygnus.com)
779 * infrun.c (wait_for_inferior): fix stepi/nexti that was broken
780 by my last edit to this routine.
782 Mon Oct 21 14:27:43 1991 John Gilmore (gnu at cygnus.com)
784 * tm-sun3.h (FIX_CALL_DUMMY): problem with cross debugging.
785 FIX_CALL_DUMMY does unaligned accesses and/or forgets to byte swap
786 the values before putting them into the dummy code. (From Peter
789 Mon Oct 21 10:04:39 1991 Steve Chamberlain (steve at rtl.cygnus.com)
791 * configure.in: added ebmon target.
793 Wed Oct 16 22:49:58 1991 John Gilmore (gnu at cygnus.com)
797 * Makefile.in: Roll VERSION to 4.2.
798 * README, TODO, WHATS.NEW: Update.
800 * core.c (core_open): Improve error message for bad file.
801 Pass .reg virtual memory address to fetch_core_registers to help
802 it find the registers in the core-file header.
803 * coredep.c (fetch_core_registers): Take new argument, use it,
804 and pass it to register_addr to locate the block of registers.
805 * xm-mips.h: Update KERNEL_U_ADDR for new scheme. Cleanup a bit.
807 * dbxread.c (read_dbx_symtab, process_one_symbol): Handle
808 Sequent N_FN_SEQ like everybody else's N_FN.
810 * main.c: Circumvent SCO cc bug with #if !!defined(USG).
811 * tm-i386v.h: #endif guck.
812 * xconfig/i386*: Remove -Dgetpagesize()=4096 kludge.
813 * xconfig/i386sco: Add HAVE_STRSTR to avoid ANSI bdeath.
814 * xconfig/tahoe: Add REGEX, which seems to be missing.
816 * coredep.c: Add <sys/types.h> for SCOnix.
817 * dbxread.c (read_dbx_symntab): Avoid coredump on malformed file.
818 * printcmd.c (print_formatted): Flush output before disassembly.
820 Tue Oct 15 20:12:32 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
822 * doc/refcard.tex (sec "Working Files"): consistent metavars and
823 other improvements, due to comments by François Pinard
824 (pinard@iro.umontreal.ca)
826 * doc/gdb.texinfo (appendix "Installing GDB"): changes in
827 configure, and improvenets related to Pinard's refcard comments
829 Tue Oct 15 08:45:12 1991 John Gilmore (gnu at cygnus.com)
831 Changes from Fred Fish:
832 * tm-68k.h (FPI_REGNUM): Add.
833 * infrun.c (child_create_inferior): flush stdout and stderr
835 * configure.in: Handle amigados, amix hosts and targets.
836 * inflow.c: Handle TIOCGLTC_BROKEN for Amiga.
839 * values.c (show_convenience): Use printf_filtered.
840 * main.c (define_command): Check result of lookup_command for
842 (echo_command): Use printf_filtered, and force output out.
844 * dbxread.c (read_enum_type): Avoid Modula-2 kludge that breaks C
846 * i387-tdep.c (double_to_i387): Fix typo for double_to_ieee_extended.
847 * utils.c (_initialize_utils): If !ISATTY, don't paginate.
848 * configure.in, tconfig/decstation, xconfig/decstation: Rename
849 dec3100 to decstation.
851 Mon Oct 14 13:37:50 1991 Roland H. Pesch (pesch at cygnus.com)
853 * doc/gdb.texinfo: Catch up to changes recorded here in ChangeLog
854 (nodes Continuing and Stepping; Memory; Targets) clarifications
857 Fri Oct 11 23:27:06 1991 John Gilmore (gnu at cygnus.com)
859 * tm-{irix3,mips,nindy960,pn,symmetry,vx960}.h: Move
860 REGISTER_U_ADDR to corresponding xm- file. Sugg. by Peter Schauer.
862 * symmisc.c (print_partial_symtabs): Add printpsyms debug cmd.
864 * m68k-tdep.c (m68k_push_dummy_frame, m68k_pop_frame): Add
865 generic routines for calling inferior functions.
867 * blockframe.c (inside_main_scope, inside_entry_scope): New.
869 * copying.awk: Filter formfeeds out of copying & warrantee.
870 Make them available as `show copying' and `show warrantee' also.
871 * main.c (print_gnu_advertisement): Advt `show' commands.
873 Thu Oct 10 17:25:47 1991 John Gilmore (gnu at cygnus.com)
875 * mach386-xdep.c: Even when cross-compiling, leave in the
876 core-file reading code.
877 * core.c (get_core_registers): Avoid coredump if no .reg section.
879 Wed Oct 9 17:03:34 1991 John Gilmore (gnu at cygnus.com)
881 * mipsread.c, coffread.c: initialise TYPE_VPTR_FIELDNO to -1.
882 This avoids coredumps under `set print object on' in value_headof
883 (called erroneously by value_from_vtable_info) for `p &struct'
884 or `p *struct'. From Peter Schauer.
886 Mon Oct 7 00:06:52 1991 John Gilmore (gnu at cygnus.com)
888 * Makefile.in: Roll version to 4.1.2.
889 * dbxread.c: Use aout64.h, not a.out.gnu.h. Get external symbol entry
890 size from BFD (but, FIXME, we don't yet read external nlists's and
891 convert them to internal nlists's before handling them -- we still
892 assume they have the same size and alignment.) Use SET_NAMESTRING
894 * exec.c (exec_file_command): Move dead coff-encapsulation code
896 * m88k-tdep.c, m88k-xdep.c: Remove encap test and #inc <a.out.h>.
898 Fri Oct 4 22:30:06 1991 John Gilmore (gnu at cygnus.com)
900 * configure.in, tm-i386v.h, xm-i386v.h: Intel 386 Mach host port.
901 * xm-i386mach.h, mach386-xdep.c, xconfig/i386mach: New files.
903 Fri Oct 4 17:04:31 1991 Per Bothner (bothner at cygnus.com)
905 More patches from Peter Schauer <pes@regent.e-technik.tu-muenchen.de>:
906 * mips-xdep.c (store_inferior_registers): Don't try to
907 write the (pseudo) FP.
908 * mipsread.c (parse_partial_symbols): Improved algorithm for
909 setting pst->texthigh.
911 Fri Oct 4 16:47:32 1991 Roland H. Pesch (pesch at cygnus.com)
913 * doc/Makefile: make TEXINPUTS include . everywhere
915 Fri Oct 4 00:35:56 1991 John Gilmore (gnu at cygnus.com)
917 * coffread.c, dbxread.c, symfile.c, symmisc.c, symtab.h: Remove
918 vestiges of typevectors, which were for symsegs and are no longer
919 used. (From a question by Eliot Dresselhaus
920 <dresselh@RFT30.nas.nasa.gov>).
922 Thu Oct 3 09:33:26 1991 John Gilmore (gnu at cygnus.com)
924 * dbxread.c, coffread.c: static-ize functions that were
925 gratuitiously external. (From Fred Fish.)
927 * c-exp.y: sym->class to SYMBOL_CLASS (sym).
929 * dbxread.c (dbx_lookup_type): Keep doubling size of typevector
930 until it is large enough.
932 * dbxread.c (read_type): Handle error case slightly better.
933 Make complaint message not C++-specific.
935 Wed Oct 2 17:21:07 1991 Stu Grossman (grossman at cygnus.com)
937 * infrun.c (wait_for_inferior): Fix step/next so that you only
938 stop at the beginning of a new line. This fixes various problems
939 with for loops, nested if-else's and switch statements.
941 Tue Oct 1 06:33:55 1991 John Gilmore (gnu at cygnus.com)
943 * symtab.c (lookup_symtab_1, lookup_symbol): "fatal" errors
944 between symtabs and psymtabs become ordinary error()s.
946 * dbxread.c (read_dbx_symtab): Relocate end_of_text_addr
947 properly, making "end pc" correct in shared lib psymtabs.
948 (From Guy Harris <guy@auspex.com>.)
950 Mon Sep 30 13:15:31 1991 John Gilmore (gnu at cygnus.com)
952 * dbxread.c: Enable, but soften, const_vol_complaint.
953 (read_dbx_symtab): N_STSYM and N_LCSYM define static vars.
954 Ditto Gould N_NBSTS and N_NBLCS. Also, all types in the psymtab
955 should be file-scope, not global.
956 (read_struct_type): Remove ancient multiple-inheritance warning.
957 (read_range_type): Check base type, complain & patch if undefined.
958 * stack.c (frame_info): Demangle the function name in `info stack'.
961 Sat Sep 28 10:02:33 1991 John Gilmore (gnu at cygnus.com)
963 * eval.c (evaluate_subexp_for_address): Don't use
964 TYPE_POINTER_TYPE directly (it might be zero if this type has
965 never had a pointer created before); use lookup_pointer_type.
966 * symtab.c (lookup_method_type): Arguments were swapped in all
967 callers, so fix it here. I'm amazed this worked at all!
969 Fri Sep 27 18:09:31 1991 John Gilmore (gnu at cygnus.com)
971 * c-exp.y, m2-exp.y: Define more yysymbols that happen to be
972 "bss" rather than "data" symbols, but which still conflict.
975 * coffread.c (coff_symfile_read): Use xmalloc, not malloc.
976 * core.c (core_files_info): Shorten output.
977 * exec.c (exec_files_info): Ditto.
978 (build_section_table): Ignore zero-length sections.
979 * language.c, printcmd.c: Lint.
980 * language.h (get_frame_language): Declare.
981 * saber.suppress: update.
982 * stack.c (find_relative_frame): Remove complex code that was
983 #if 0'd, stick with simple code. Lint.
984 * saber.suppress: Update a bit.
985 * symfile.c (add_symbol_file_command): Add "?" to question.
986 * utils.c (parse_escape): Avoid \a due to bdead compilers.
987 * value.h: Declare typedef_print.
989 * valprint.c (val_print, type_print_base): TYPE_CODE_RANGE less
992 * nindy-tdep.c (nindy_frame_chain_valid): Use lookup_misc_func.
993 (Reported by Mark Peek <mark@imagen.com>.)
995 * solib.c (solib_map_sections): Relocate all sections, even
996 though only the text section's size is tracked. Mark ld_text
997 for eventual elimination as we generalize to N sections.
999 * infrun.c (wait_for_inferior): Don't check if the PC is in a
1000 call_dummy if we were stopped by a random signal that is being
1001 passed to the program. This produced wierd results when calling
1002 functions in the inferior and signals (e.g. SIGALRM) were in use.
1004 Tue Sep 24 18:05:30 1991 John Gilmore (gnu at cygnus.com)
1006 * infrun.c (IN_SIGTRAMP): Not parenthesized properly.
1007 Bugfix from Paul Eggert <eggert@twinsun.com>.
1008 * tm-ultra3.h (IN_SIGTRAMP): Ditto.
1009 * valprint.c (print_floating): Print 9 digits for IEEE floats.
1012 Mon Sep 23 15:50:07 1991 John Gilmore (gnu at cygnus.com)

1018 Fri Sep 20 16:10:52 1991 John Gilmore (gnu at cygnus.com)
1022 * Makefile.in (VERSION): Set to 4.1.
1023 * language.c (set_language_command): Print useful help message,
1024 and restore the language string after giving help.
1025 * valprint.c (typedef_print): Print typedef in C or M2.
1026 * symtab.c (list_symbols): Use it.
1027 * main.c (main): Avoid any output before (gdb) prompt when -q.
1028 * language.c (set_language_command): Handle errors by restoring
1029 the language string to its current state (fix from A. Beers).
1030 * doc/gdbint.texinfo: Roll in information from README. Rearrange
1031 "how to install" and "how to print the doc" stuff so it drops
1033 * configure.in: Rename rtpc CPU to romp to match config.sub.
1034 * README, WHATS.NEW, TODO: Update for gdb-4.1.
1036 Fri Sep 20 17:39:14 1991 Roland H. Pesch (pesch at cygnus.com)
1038 * doc/gdb.texinfo: Updates from ChangeLog. set/show write,
1039 autoloading shared libs, copyright etc on GDB startup, clean up $_
1040 and $__ index refs, set/show listsize and related updates to list
1041 cmd. New host/target configs.
1043 Fri Sep 20 15:46:00 1991 Roland H. Pesch (pesch at cygnus.com)
1045 * doc/Makefile: generate aux version-no file doc/gdbVN.m4
1046 from main Makefile.in version definition
1047 doc/gdb.texinfo: use version recorded in doc/gdbVN.m4 for current
1049 Makefile.in (setup-to-dist): generate doc/gdbVN.m4
1051 * doc/gdb.texinfo: merge new language-switching and lang-specific
1054 Fri Sep 20 15:00:57 1991 Per Bothner (bothner at cygnus.com)
1056 * mcheck.c: Add __ONEFILE kludge to allow compilation by non-ANSI
1057 compilers (which may lack stddef.h).
1059 Fri Sep 20 13:29:42 1991 John Gilmore (gnu at cygnus.com)
1061 * dbxread.c (read_dbx_symtab, process_one_symbol): N_FN and
1062 N_WARNING are the same except for the N_EXT bit, so just use their
1063 values alone, rather than OR-ing them with N_EXT.
1065 Fri Sep 20 12:27:55 1991 Stu Grossman (grossman at cygnus.com)
1067 * mipsread.c (parse_lines): Deal with negative extended line
1070 * c-exp.y, m2-exp.y: #define yyerrflag and yynerrs to avoid
1071 global symbol conflicts.
1073 Fri Sep 20 02:28:15 1991 John Gilmore (gnu at cygnus.com)
1075 * .gdbinit: Move 'set complaints' to top, so it runs even in
1076 case we aren't debugging GDB.
1077 * language.c (_initialize_language): Fix type check and range
1078 check documentation strings.
1079 * utils.c (!HAVE_VPRINTF): Define vfprintf as a function, so
1080 language.c can use it. (Though language.c should really not be
1081 handling warnings/errors the way it does, FIXME.)
1082 * symtab.c (lookup_primitive_type): const lint.
1084 Bugfix from Peter Schauer:
1085 * source.c (lines_to_list): Make signed, to avoid comparison
1086 going unsigned and complaining that -3 is too high for 21 lines.
1087 * stack.c (lines_to_list): Ditto.
1089 Thu Sep 19 23:33:41 1991 John Gilmore (gnu at cygnus.com)
1091 * Makefile.in (HFILES): Add minimon.h.
1092 (VERSION): Roll version number to 4.0.95.
1093 (gdb.tar.Z, make-proto-gdb.dir, setup-to-dist, gdb-XXX.tar.Z):
1094 New rules for building distributions. Normal distribution
1095 is built by doing `make -f Makefile.in gdb.tar.Z' in the directory
1096 one level up from here; it calls make-proto-gdb.dir to build a
1097 directory `proto-gdb' which is an image of the release. The old
1098 `gdb.tar.Z' rule still works too.
1099 * config.sub, configure: Roll in latest from ..
1101 Thu Sep 19 17:41:24 1991 Roland H. Pesch (pesch at cygnus.com)
1103 * doc/gdbint.texinfo: Reorder contents; reorganize new-host,
1104 new-target, and new-config chapters; fix minor typos; come closer
1105 to usual GNU markup conventions for @file @samp @code @var.
1107 Thu Sep 19 17:04:12 1991 Per Bothner (bothner at cygnus.com)
1109 Patches from Peter Schauer <pes@regent.e-technik.tu-muenchen.de>:
1110 * mipsread.c (parse_partial_symbols): Enter the name of all
1111 structs/unions... into the psymtab so we can access them if the
1112 symtab is not read in.
1113 * mips-tdep.c: Remove some unneeded #includes.
1114 * xconfig/dec3100: Add HAVE_STRSTR.
1116 Thu Sep 19 15:14:23 1991 John Gilmore (gnu at cygnus.com)
1118 * Makefile.in: Circumvent Sun Make bug on *-exp.tab.o.
1119 * c-exp.y, m2-exp.y: Lint.
1120 * m2-exp.y: Avoid using yytname[] which is a Bison-ism.
1121 * valprint.c (val_print_fields): Check for stub type.
1122 * mipsread.c (_initialize_mipsread): Avoid using
1123 builtin_type_void at initialize time.
1124 (mipscoff_symfile_read): use it now.
1126 Wed Sep 18 15:55:51 1991 John Gilmore (gnu at cygnus.com)
1128 Merge multiple-language support, and partial Modula-2 support,
1129 from Andrew Beers <beers@cs.buffalo.edu>.
1131 * i387-tdep.c: New file, consolidates most 80387 support,
1132 and eliminates host dependency on double<->extended conversions.
1133 * i386-xdep.c, symm-xdep.c: Remove most 387 support.

1136 * symfile.c (allocate_symtab): New fn, consolidates the work
1137 of allocating and initializing a new struct symtab. Set the
1138 language of the symtab based on its filename extension.
1139 * symfile.h: Declare it.
1140 * mipsread.c (new_symtab): Use it. Minor formatting changes.
1141 * dbxread.c (end_symtab): Use it.
1143 * mipsread.c (parse_symbol, case stParam and stProc): Add #if 0'd

1150 * coffread.c (end_symtab): Use allocate_symtab.
1151 (process_coff_symbol): #if 0'd for functions and params as above.
1152 (read_enum_type): Recognize Modula-2 BOOLEAN.
1153 * symtab.c (add_param_to_type): #if 0'd function to add a
1154 parameter type to a function type's field list.

1157 * i386-xdep.c, pyr-tdep.c, pyr-xdep.c, remote-vx.c, solib.c,
1158 source.c, symfile.c, dbxread.c, breakpoint.c, core.c, exec.c,
1159 i387-tdep.c, infcmd.c, mips-tdep.c, stack.c, printcmd.c: Output
1160 hex with local_hex_string for Modula-2 support.
1162 * breakpoint.c (breakpoint_cond_eval): Use new value_true to test
1163 breakpoint condition language-independently.
1165 * parse.c: New file with the common code remains of expread.y.
1166 * parser-defs.h: New file with common declarations from expread.y.
1167 * c-exp.y: New file with the C parser from expread.y, and other

1170 * expread.y, expread.tab.c: Remove.
1171 * breakpoint.c, eval.c, printcmd.c, expression.h: Use
1172 parse_expression and parse_exp_1 rather than parse_c_expression
1175 * symtab.h (enum languages): Move to defs.h.

1189 TYPE_CODE_BOOL and TYPE_CODE_CHAR.
1191 * expression.h (enum exp_opcode): Add Modula-2 specific opcodes.
1192 * expprint.c: Look up expression opcodes in language-specific

1205 * language.h, language.c: New files for language-specific macros,
1206 declarations, and definitions.
1210 * main.c (main): If error() is called during early

1225 Tue Sep 17 08:37:41 1991 John Gilmore (gnu at cygint.cygnus.com)
1227 Add Andrew Beers' changes for Modula-2 support. His ChangeLog
1228 entries are enclosed herein. Not all of these changes
1229 have been merged into the master GDB sources -- check the
1230 ChangeLog above here for the merge log.
1232 Mon Jun 3 17:05:45 EDT 1991
1234 m2-exp.y Created. Tested outside of GDB for a few days. Proper
1235 operators were added, C specific operators and tokens
1236 removed. yylex() revamped to some extent. Still things
1237 missing from the grammar, such as sets.
1238 Tested for two weeks in GDB v3.5.
1240 Tue Jun 11 17:23:48 EDT 1991
1242 m2-exp.y Added boolean constants TRUE and FALSE to the grammar
1243 so they are built-in. Sort of a hack.
1245 Fri Jun 14 12:53:51 EDT 1991
1247 m2-exp.y Added range checking for numeric constants. Any numeric
1248 constant is assumed to be of builtin type INTEGER unless:
1249 (1) it is octal or hexadecimal, in which case it is a
1250 CARDINAL; (2) it is too big to fit into an INTEGER, in
1251 which case it is a CARDINAL.
1252 eval.c Added simple range checking for +, -, and * on integers.
1253 Doesn't work very well for *, since 6 * 1,000,000,000 =
1254 1,705,032,704, which fails the simple test of result >=
1255 first_operand, no matter in what order the operands are.
1257 Tue Jun 18 14:11:30 EDT 1991
1259 Broke the parser into parts, one containing the C grammar and the other
1260 containing code to be shared by all of the grammars.
1262 The following files no longer exist:
1267 The following files were added:
1269 c-exp.y (The C grammar)
1270 m2-exp.y (The Modula-2 grammar)
1271 parser-code.c (Code that is shared by the above grammar)
1275 Makefile.dist Changed to reflect the above dependencies. NOTE: It is
1276 now necessary to use the Bison compiler compiler, since it
1277 will generate function/variable prefixes other than yy.
1279 Tue Jun 18 16:47:49 EDT 1991
1281 symtab.[ch] Added the external variable working_lang, than holds the
1282 value of the current working language.
1283 Added the ennumerated type language_mode, with the values
1284 language_auto and language_manual, the former meaning that
1285 GDB sets working_lang as needed, and the latter meaning
1286 that the value of working_lang is totally under user
1288 symtab.[ch] Added the Modula-2 pervasive types INTEGER, CARDINAL,
1289 REAL, BOOLEAN and CHAR. Also added the type codes
1290 TYPE_CODE_BOOL and TYPE_CODE_CHAR.
1291 utils.c Added set_language_command and show_language_command to
1292 implement the GDB support commands "set language" and
1294 expression.h A number of identifiers were added to the type exp_opcode
1295 to facilitate Modula-2 builtin functions, integer
1296 division, and array indexing.
1298 Wed Jun 19 13:25:58 EDT 1991
1300 language.h Added the macro STRICT_TYPE, which evaluates to non-zero
1301 if the language specified by working_lang requires the use
1302 of strict typing of expressions. Eventually, even this
1303 will be able to be changed by the user.
1304 Added the macro RANGE_CHECK, which evaluates to non-zero
1305 if the language specified by working_lang requires the
1306 checking of a value against the domain of its type.
1307 Eventually, even this will be able to be changed by the
1309 language.[ch] Predicates involving types (simple_type, ordered_type,
1310 same_type, integral_type, numeric_type, character_type,
1311 boolean_type, float_type) are added. These predicates are
1312 based on the current value of working_lang, and are handy
1315 Wed Jun 19 15:39:34 EDT 1991
1317 eval.c Added the function type_array_rank which computes the rank
1319 valarith.c Added the funtion value_bool, which when given a integer
1320 value.h value (ie. struct value *) as an argument, it returns a
1321 boolean value (ie. struct value *) true if that integer
1322 is non-zero, and a boolean value false otherwise.
1323 valprint.c Added cases for TYPE_CODE_BOOL, so Modula-2 BOOLEAN values
1324 will print out properly.
1326 Wed Jun 19 16:36:34 EDT 1991
1328 valops.c Added the function value_capitalize, which returns it
1329 value.h argument capitalized if its argument is a lowercase
1330 letter, or the argument unchanged if its argument is not a
1332 valarith.c Added the function range_check_p, which returns non-zero
1333 value.h if its value argument is between the integral bounds upper
1335 Added the function range_check_enum_p, which makes sure
1336 that its value argument is a valid member of the domain of
1338 Added the function range_check_range_p, which makes sure
1339 its value argument lies between the upper and lower bounds
1340 of its type argument, which must be a ranged type.
1341 Added the function check_array_index, which range and type
1342 checks an index of an array.
1343 Added the function value_multi_subscript, which computes
1344 array[idx1,idx2...idxN], given a value array and an array
1345 of values representing indicies.
1346 values.c Changed value_from_long to work with TYPE_CODE_CHAR and
1347 unpack_long to work with TYPE_CODE_BOOL and
1350 Wed Jun 19 18:04:08 EDT 1991
1352 symtab.c Stored pervasive types in a structure and make
1353 lookup_pervasive_type() a lookup function that was based
1354 on working_lang. If lookup_pervasive_type() returned
1355 non-zero, then that value was returned (a fix, since
1356 before it simply wouldn't return the pervasive type.)
1357 language.h Added the macro CAST_IS_CONVERSION, which evaluates to
1358 non-zero if the language specified by working_lang means
1359 "conversion" when it says "cast".
1360 valops.c Added the function value_real_cast(), which performs a
1361 value.h *cast*, not a *conversion*, which is what value_cast()
1362 does when it can. In particular,
1363 value_cast(<float_type>,4) = 4.0, while
1364 value_real_cast(<float_type>,4) = some mess.
1365 eval.c Modula-2 builtin functions implemented: ABS, CAP, CHR,
1366 parser-code.c FLOAT, HIGH, MAX, MIN, ODD, ORD, TRUNC, and VAL.
1367 expression.h Added macros MAX_OF_TYPE and MIN_OF_TYPE to work with MAX
1368 and MIN on integral types. *NOTE*: These are currently
1369 hardcoded to work only if there are 8 bits per storage
1371 eval.c Made logical functions call value_bool to return a
1372 properly typed boolean value, based on working_lang.
1374 Thu Jun 20 11:55:27 EDT 1991
1376 valprint.c Types now print out in a Modula-2 fashion. This works for
1377 the cases when the type is printed out step-by-step, that
1378 is, it doesn't work when the name of a structured type
1379 (which includes the keyword "struct", etc.) is simply
1381 FIXME: Perhaps this is bad. Parts of it seem to kludgey,
1382 since type specifications in C and Modula-2 are very
1383 different. The C printing of a type is very recursive,
1384 whereas in Modula-2 it is generally very simple. C has
1385 type prefixes and suffixes, which have no real analogue in
1386 Modula-2. Maybe type_print() should call a language
1387 specific type printer. This is also advantageous if we
1388 compile GDB to exclude some of the languages. We'll just
1389 leave those functions out.
1391 Thu Jun 20 16:57:10 EDT 1991
1393 dbxread.c When reading the complete symbol table in (via
1394 psymtab_to_symtab()), the number and types of function
1395 arguments are added to a function type. define_symbol()
1396 calls add_param_to_type() to accomplish this.
1397 Assumption: when we come across a function definition
1398 (N_FUN symbol with an 'f' or 'F' in the name), its
1399 arguments will appear before another function definition.
1400 When a function is found, a pointer to its type is placed
1401 in the global in_function_type. Changes that
1402 add_param_to_type() makes are to this global.
1403 valprint.c The type of a function now includes (for Modula-2) the
1404 types of its parameters.
1405 eval.c Type checking and a check for the proper number of
1406 arguments is now done for function calls. Not sure of the
1407 impact this has on C++ member function yet.
1409 Thu Jun 20 19:58:48 EDT 1991
1411 valprint.c Rewrote the type printer. Broke it into two language
1412 specific parts, adding the functions type_print_m2() and
1414 An unfortunate consequence is this: if you debugging a C
1415 program in Modula-2 mode (why?), info types does not work
1416 well with regular expressions, since the types are printed
1417 out in Modula-2 terminology, but stored in C terminology.
1418 language.[ch] Added the functions new_type_last(), type_keyword(), and
1419 type_sep() to aid in the printing of typedefs.
1420 symtab.c Made the printing of typedefs as language independent as
1421 possible through calls to new_type_last(), type_keyword(),
1424 Fri Jun 21 11:50:26 EDT 1991
1426 dbxread.c Check all incoming ennumerated types. If it looks like
1427 Modula-2's BOOLEAN type, then change the type_code of the
1428 type to TYPE_CODE_BOOL so we can process it as a boolean
1430 valprint.c Replaced some of the 0x%x with calls to sprintf and
1431 hexformat() in val_print().
1432 language.[ch] Added the function hex_to_string(), which converts its
1433 integral argument to a hexadecimal number (format is
1434 language based) and returns the result as a string.
1436 Mon Jun 24 12:25:07 EDT 1991
1438 valprint.c Some functions call type_print_1() directly, instead of
1439 value.h using type_print(), so they can specify where (column) to
1440 print things. Since type_print() takes care of language
1441 dependence, that needs to be called first. Added a
1442 parameter depth to type_print() (so it is now like
1443 type_print_1). Changed type_print to type_print_at, and
1444 made type_print a macro that passes a depth argument of
1446 symmisc.c Changed all calls to type_print_1 to calls to
1448 Makefile.dist Made it possible to build GDB for a specific set of
1449 depend languages. Do this by passing a definition for the macro
1450 LANGS to make. LANGS should be a string containing a
1451 space-separated list of language names (ie. LANGS="c m2").
1452 The default is to build all languages. Note that grammar
1453 files must follow the naming convention of <lang>-exp.y.
1454 gdb.lang This holds the current value of the LANGS macro. It is
1455 examined every time make is called, and is updated if
1457 eval.c Added #ifdef _LANG_<lang> to these files.
1458 expread.c Still need to add them to dbxread.c and coffread.c.
1466 Mon Jun 24 16:33:11 EDT 1991
1468 language.[ch] Added the functions hexformat_pre() and
1469 hex_to_string_pre(), which take a prefix argument to
1470 include in the format string. Thus, hexformat_pre("08") will
1471 return "0x08x" (if the working language is language_c).
1472 Made hexformat() and hex_to_string() calls to the above
1473 with "" as the prefix argument.
1475 am29k-pinsn.c, arm-pinsn.c, breakpoint.c, convex-tdep.c, exec.c, core.c,
1476 dbxread.c, i386-pinsn.c, i386-stub.c, i386-xdep.c, i960-pinsn.c,
1477 infcmd.c, inflow.c, m68k-pinsn.c, m68k-stub.c, m88k-pinsn.c,
1478 mips-pinsn.c, mips-tdep.c, ns32k-pinsn.c, printcmd.c, pyr-pinsn.c,
1479 pyr-tdep.c, pyr-xdep.c, remote-vx.c, remote.c, solib.c, source.c,
1480 stack.c, sun386-xdep.c, symfile.c, symm-xdep.c, symmisc.c, tahoe-pinsn.c,
1481 valprint.c, vax-pinsn.c
1483 Changed all occurences of 0x%[0-9]*l*x in printf format strings to
1484 calls to hexformat() and hex_to_string(). Format strings without
1485 the leading "0x" were ignored.
1487 depend Updated to take the above into account.
1490 Tue Jun 25 15:27:18 EDT 1991
1492 symtab.h Added the types range_mode_t, range_check_t, type_mode_t,
1493 and type_check_t to keep track of the current state of
1494 range and type checking.
1495 main.c Added the variables range_mode, range_check, type_mode,
1496 and type_check to record the current state of range and
1497 type checking. Added initialization code to main().
1498 language.h Changed the macros STRICT_TYPE and RANGE_CHECK to examine
1499 the above variables.
1502 Tue Jun 25 17:57:08 EDT 1991
1504 dbxread.c process_one_symbol() updates the variable (enum language)
1505 source_lang based on the extension of the filename
1506 contained in the N_SO sybmol that started this symtab.
1507 When end_symtab() is called, the value of source_lang is
1508 put into the language field.
1509 stack.c select_frame() sets working_lang (and possibly type_check
1510 and range_check) to the language field of the symtab
1511 associated with the frame that is selected if working_mode
1512 is language_auto. If working_mode is language_manual, a
1513 warning is printed and working_lang is not set.
1514 language.c Added the function set_type_range(), which sets the value of
1515 type_check and range_check (if their modes call for
1516 automatic setting) based on the current value of
1517 working_lang. A non-zero argument will cause the current
1518 settings to be output.
1521 Wed Jun 26 14:51:40 EDT 1991
1523 eval.c Added range checks on assignment.
1524 m2-exp.y Added the grammar for sets to the language. Currently,
1525 these do not do anything except print an error message.
1527 Wed Jun 26 17:01:04 EDT 1991
1529 m2-exp.y Added the ability for parse_number() to parse negative
1530 numbers. A global flag is set upon encountering a unary
1531 minus. This was done to make, for example, 1 parse as a
1532 CARDINAL, and not as an integer, per Wirth's examples in
1533 Programming in Modula-2 ed.4.
1534 valprint.c Added support for "set radix 2" by then setting
1535 output_format to 't'.
1536 eval.c Implemented range checking on subrange types. Added calls
1537 to range_check_range_p for BINOP_ASSIGN and BINOP_VAL.
1538 Implemented MIN and MAX for ennumerated types. The
1539 minimum value of an ennumerated type is defined by Wirth
1540 as the first identifier, and the maximum as the last.
1541 m2-exp.y Made octal numbers ending with "B" be characters and those
1542 ending with "C" be numbers, per Wirth's book. (p. 34)
1544 Thu Jun 27 14:11:52 EDT 1991
1546 stack.c select_frame() now only sets working_lang, it does not
1547 notify the user. If working_mode is language_manual, then
1548 a warning is issued once.
1549 main.c At the end of each call to execute_command(), working_lang
1550 is checked against the local static (enum language)
1551 current. If they differ and working_mode is
1552 language_auto, the new settings of language, type and
1553 range checking are printed out.
1554 stack.c Modified frame_info() to include the language of the
1555 current frame in the output of "info frame".
1556 language.[ch] Added the function language_str() which returns the name
1557 of the current language.
1559 Fri Jun 28 15:33:14 EDT 1991
1561 m2-exp.y Added the built-in procedures INC, INCL, DEC, and DECL to
1562 the language. INCL and DECL currently cause an error,
1563 since sets are not implemented yet. INC and DEC are
1564 implemented as PREINCREMENT/PREDECREMENT with one
1565 argument, and as ASSIGN_MODIFY with two arguments.
1566 eval.c Added type checking to the above cases.
1567 value.h Added not_lval_constant to the lval_type ennumerated type.
1568 not_lval_constant means that the value is a constant
1569 value; that is 3 or 'a' or TRUE, not as in a constant
1570 identifier. This is used to help coerce numbers such as 3
1571 to either signed or unsigned numbers.
1572 valops.c Added the function value_coerce_constants() which coerces
1573 constant integers as following: if one is a constant and
1574 the other is not, the constant's type is set to the type
1575 of the other argument. If both are constants and one is
1576 signed, the other is converted to a signed constant.
1578 Sat Jun 29 17:26:29 EDT 1991
1580 valarith.c Added a better range checker. It now checks range
1581 (successfully) on integral operations [+-] (signed and
1582 unsigned) for any C sized type. Still does not work well
1583 for multiplication.)
1584 int_in_size() returns an integer that is coerced to fit into
1585 specified number of bytes.
1587 Mon Jul 1 13:04:14 EDT 1991
1589 language.[ch] Added the function binop_result_type(), which returns the
1590 builtin (struct type *) type that would be the result of a
1591 binop on the two values V1 and V2.
1593 Wed Jul 3 19:22:53 EDT 1991
1595 source.c Extended source_info() to include the source language in
1596 the output from "info source".
1598 Fri Jul 5 13:48:52 EDT 1991
1600 utils.c Moved the support functions for the GDB set/show commands
1601 dealing with language into language.c.
1602 language.c Added the function language_info(), which displays info
1603 about the current working language, type and range check
1604 settings. Called via the GDB command "info language".
1605 Added an initialization routine _initialize_language(),
1606 that sets defaults for the language, type and range
1607 variables and sets up the new GDB commands.
1608 main.c Language setup moved to language.c.
1611 Mon Jul 8 10:10:22 EDT 1991
1613 valarith.c Debugged the range checker for arithmetic. Still does not
1614 work for multiplication very well.
1616 Mon Jul 8 12:40:37 EDT 1991
1618 language.[ch] Added the function value_true() which returns non-zero if
1619 its argument represents a boolean true value.
1620 breakpoint.c Changed breakpoint_cond_eval() to call value_true() to
1621 check the truth of an expression.
1623 Thu Jul 11 12:51:34 EDT 1991
1625 language.[ch] Added the predicate structured_type(), which returns
1626 non-zero if the argument is a structured type.
1627 Added the predicate pointer_type(), which returns non-zero
1628 if the argument is a pointer type.
1629 eval.c Added the ability to do addition and substraction on
1630 pointers and integers. This case simply bypasses the
1633 Thu Jul 11 14:41:42 EDT 1991
1636 Added the symbol N_DEFD (0x4a) which is a definition
1637 module dependency that is used by the GNU Modula-2
1638 compiler and the linker. It is not important to GDB,
1639 except that [dbx|coff|mips]read.c should ignore these
1642 Fri Jul 12 16:07:00 EDT 1991
1644 valprint.c Changed the TYPE_LENGTH(type) >= 0 to TYPE_LENGTH(type) >
1645 0 in val_print(). Also added statements to the else part
1646 to coerce type (argument to val_print) to a pointer type
1647 if it is an "array of unspecified length".
1648 valops.c Added the function value_m2_string(), which returns a
1649 (value) value which is a constant string, whose type is
1650 (ARRAY [0..n] OF CHAR). The length field of the type
1651 structure is set to zero, so it will be interpreted as an
1652 "array of unspecified length".
1653 stack.c Moved the language/frame mismatch check to
1654 main.c:execute_command().
1655 main.c The working language is recorded each time
1656 execute_command() is executed. If working lang has
1657 changed during its execution, then the new
1658 language/type/range info is printed out for the user. If
1659 the working language does not match the language of the
1660 frame, a warning is issued.
1662 Sat Jul 13 16:16:39 EDT 1991
1664 eval.c Moved all the type-checking stuff for operators to
1665 language.[ch] language.c. This is so we can keep language-specific
1666 stuff (like for what type operators are defined) in
1668 language.[ch] Added the function binop_type_check(), which checks to see
1669 if its two (value) arguments are type-compatible with its
1670 opcode argument. The opcode should represent an operation
1671 involving an operator. Also added the macro function
1672 unop_type_check, which calls binop_type_check with a
1673 NULL second argument.
1674 expprint.c Added Modula-2 operators to the op_print_tab, so info
1675 expression.h break works correctly. Also added "op_string", which
1676 returns the string corresponding to the (enum exp_opcode)
1677 opcode that is its argument.
1680 Sat Jul 13 18:26:18 EDT 1991
1682 coffread.c Added code to record the type of function arguments with
1683 each paricular function. Code is very similar to that
1685 dbxread.c Moved add_param_to_type() to symtab.c
1686 symtab.[ch] Added function add_param_to_type() from dbxread.c
1688 *** NOTE: The above additions have not been tested.
1690 Mon Jul 15 12:50:47 EDT 1991
1692 langauge.[ch] Added the functions type_error and range_error, which work
1693 like error() except if the type/range mode is set to
1694 *_mode_warn, then they do not do a return_to_top_level(),
1695 but merely print a warning.
1696 Also changed [set|show]_[type|range]_command() to support
1697 the new "warn" feature.
1699 Thu Jul 18 17:50:54 EDT 1991
1701 mipsread.c Added code to record the type of function arguments with
1702 each particular function. Code is very similar to that
1705 *** NOTE: The above additions have not been tested.
1707 Fri Jul 19 11:19:10 EDT 1991
1709 defs.h Added macros MAX_OF_SIZE, MIN_OF_SIZE, UMAX_OF_SIZE, and
1710 UMIN_OF_SIZE, which when given a size of a numeric type,
1711 return the maximum and minimum value it can hold. UMAX...
1712 and UMIN... return the result for unsigned types.
1713 symtab.h Added the macros MAX_OF_TYPE and MIN_OF_TYPE to operate on
1714 struct types. They call above macros.
1715 dbxread.c Renamed the MAX and MIN_OF_TYPE macros to ..._OF_CTYPE to
1716 avoid a name conlict with the above.
1717 c-exp.y Added range checking on numeric constants in
1718 parse_number() for completeness.
1719 valarith.c Made binop_user_defined_p() and unop_user_defined_p()
1720 return 0 if working_lang is not language_c.
1722 Thu Aug 8 14:17:22 EDT 1991
1726 breakpoint.c Documentation strings of some commands changed to
1727 eliminate the references to the C language where
1730 Tue Aug 13 15:48:03 EDT 1991
1732 m2-exp.y Added qualified identifiers to the grammar. The semantics
1733 are slightly different from those of the GDB operator ::
1735 m2-exp.y Added a rule to each grammar of the form: start ::= exp |
1736 type_exp, where type_exp is any valid type expression.
1738 eval.c Added the opcode OP_TYPE, and an error case in eval.c.
1739 printcmd.c Modified ptype_command() so it actually parses the input
1740 (necessary for type expressions with scope qualifiers).
1741 Added the function ptype_eval() which expects an
1742 expression composed of one OP_TYPE element.
1743 *.[ch] Replaced all occurences of parse_c_expression with
1745 *.[ch] Replaced all occurences of parse_c_1 with parse_exp_1
1747 [End of ChangeLog entries from Andrew Beers for Modula-2 support.]
1749 Mon Sep 16 17:19:46 1991 John Gilmore (gnu at cygnus.com)
1751 Small fixes from Peter Schauer:
1753 * infrun.c (child_attach): Lint.
1754 * solib.c (find_solib): Handle shared libs version 2.
1756 Small fixes from David Wood:
1758 * xm-ultra3.h (SYS_SIGLIST_MISSING): Typo.
1762 * remote-vx.c: Move <stdio.h> to top, for FILE. Fix from
1763 John S <basrai%kanga.dnet@c3po.sm-alc.af.mil>.
1765 * utils.c (wrap_here): Avoid wrap action of fputs_filtered if
1766 chars_per_line is at maximum (user typed `set width 0'). Fix
1767 from Andreas Schwab <schwab@ls5.informatik.uni-dortmund.de>.
1769 Tue Sep 17 17:31:04 1991 Stu Grossman (grossman at cygnus.com)
1771 * coredep.c: include ptrace.h where necessary.
1772 * mipsread.c(parse_lines): fix unsigned char problem that was
1773 messing up line numbers on SGI's and possibly other MIPS based
1775 * infrun.c (child_create_inferior): use better test to check
1776 return val from setpgrp().
1777 * tm-irix3.h, xm-irix3.h, tconfig/irix3, xconfig/irix3: add these
1778 for sgi/irix support.
1780 Wed Sep 18 04:33:31 1991 Per Bothner (bothner at cygnus.com)
1782 * mipsread.c (parse_symbol): Put non-static procedures
1783 in the global block.
1785 Fri Sep 13 00:14:52 1991 John Gilmore (gnu at cygnus.com)
1787 Patch together `text_start' and `text_end' for 29K port.
1789 * exec.c (exec_command): If NEED_TEXT_START_END, define the
1790 variables and set them based on the exec file.
1791 * am29k-tdep.c: declare text_start.
1792 * valops.c (call_function_by_hand): declare text_end.
1794 * inferior.h: Eliminate CANNOT_EXECUTE_STACK in favor of
1795 defining CALL_DUMMY_LOCATION as BEFORE_TEXT_END. This is
1796 because machines that do this will also have to know to
1797 set NEED_TEXT_START_END. Besides, it was a redundant way to
1799 * tm-29k.h, tm-convex.h, tm-np1.h: Eliminate
1800 CANNOT_EXECUTE_STACK, define CALL_DUMMY_LOCATION and
1801 NEED_TEXT_START_END.
1803 Thu Sep 12 00:22:24 1991 John Gilmore (gnu at cygint.cygnus.com)
1805 AMD 29000 changes from David Wood <wood@david.ultra.nyu.edu>:
1807 * Makefile.in (CLIBS): Put XM_CLIBS and TM_CLIBS at end.
1808 Pass MUNCH_DEFINE to munch whenever we run it.
1809 * am29k-pinsn.c (print_insn): Handle NOP specially. Avoid %#x
1810 format string; use 0x%x instead.
1811 * am29k-tdep.c: Use DUMMY_SAVE_GREGS and RETURN_REGNUM.
1812 * ultra-xdep.c, xm-ultra.h: New files for Ultracomputer host system.
1813 * xm-rtbsd.h: New host support for RT/PC running BSD Unix.
1814 * inflow.c: Handle `short' process group IDs.
1815 * infptrace.c (fetch_register): Support CANNOT_FETCH_REGISTER,
1816 and check for ptrace errors.
1817 * coffread.c (SDB_REG_TO_REGNUM): Define if not already.
1818 (coff_symfile_init): Initialize text_bfd_scnum.
1819 (read_coff_symtab): Use it to find the text [and absolute?] sections.
1820 * ../config.sub: Add vendor nyu and os "sym[1-9]*".
1821 * configure.in: Add hosts rtpc-*-* and a29k-*-*.
1822 Merge target arm case with other "easy" cases. Add target
1823 cases a29k-*-none (rehack of am29k), a29k-*-kern (remote to
1824 Ultracomputer kernel), and a29k-*-sym1 (ultracomputer OS's user
1826 * minimon.h, remote-adapt.c, remote-mm.c: Add.
1827 * munch: Cope with RT/PC putting fns in data segment.
1828 Restore ability to override `nm' by specifying MUNCH_NM.
1829 * xconfig/rtbsd, xconfig/ultra3: New host systems.
1830 * tconfig/a29k: Rename from tconfig/am29k. Add remote-mm
1831 and remote-adapt. Remove encapsulated coff #define's (the
1832 support should go in BFD, and gdb shouldn't know or care).
1833 * tconfig/a29k-kern: Same, but for remote kernel debugging.
1834 * tconfig/ultra3: For debugging user processes on Ultra3/Sym1.
1835 * tm-29k.h: Update BADMAG (though it should go away).
1836 Allow the register definitions to be overridden in another
1837 tm-file. Fix SR_REGNUM. Add a mess of _REGNUM's. Separate
1838 RETURN_REGNUM from GR96_REGNUM and DUMMY_SAVE_GREGS from
1839 DUMMY_SAVE_GR96, for handling kernel calling conventions
1840 that use GR64+ rather than GR96+.
1841 * tm-ultra3.h: New file, for use on Ultra3 Unix as well as for
1842 remote debugging of Ultra3 kernel. Includes tm-29k.h and
1843 overrides various things.
1845 * remote-mm.c (mm_attach, mm_wait): Handle attach like
1846 child_attach does, making a clean stop in the newly attached
1848 * remote-eb.c: Lint.
1850 * coffread.c: Make coffread independent of any particular
1851 variant of COFF. Avoid #include-ing any particular one except
1852 internalcoff.h. BFD now passes key values for symbol reading
1853 as part of its coff_data structure (LINESZ, SYMESZ, AUXESZ,
1854 and the symbol masks and shifts); use them.
1855 Remove obsolete end_of_text_addr.
1857 * exec.c: Remove unused include files.
1859 Wed Sep 11 19:38:44 1991 John Gilmore (gnu at cygint.cygnus.com)
1861 * Makefile.in (documentation targets): Pass $(M4).
1862 Bugfix from eggert@twinsun.com (Paul Eggert).
1864 * stack.c (down_silently_command): Check for stack existence.
1866 Tue Sep 10 23:08:29 1991 John Gilmore (gnu at cygint.cygnus.com)
1868 * Makefile.in (VERSION): Update to 4.0.3.
1870 Tue Sep 10 09:19:29 1991 John Gilmore (gnu at cygint.cygnus.com)
1872 * core.c (core_file_command): Print frame at coredump with
1873 its level number, by calling print_stack_frame.
1874 * frame.h: Add selected_frame_level, print_stack_frame.
1875 * frame.h, stack.c: Remove print_sel_frame, print_selected_frame.
1876 * convex-tdep.c, convex-xdep.c, infcmd.c, inflow.c, infrun.c:
1877 Change print_sel_frame and print_selected_frame callers to
1880 * dbxread.c (read_ofile_symtab): Avoid empty else clause.
1881 * symfile.c (free_named_symtabs): Ditto.
1882 * main.c (main): wrap_here needs an arg.
1883 * solib.c (find_solib): Avoid memory access if _DYNAMIC is zero.
1884 (solib_add): Avoid noise.
1885 (solib_create_inferior_hook): Lint.
1886 (sharedlibrary_command): Move dont_repeat to here.
1887 * utils.c (error): Call wrap_here to force buffered output.
1889 Small patches from Peter Schauer:
1891 * coffread.c (start_symtab): Free any existing line_vector before
1893 (read_coff_symtab): Ditto for type_vector.
1895 * source.c (lines_to_list): New variable, replacing function.
1896 (all uses): Use as variable.
1897 (_initialize_source): Add 'set listsize' and 'show listsize'.
1898 * utils.c (lines_to_list): Remove function.
1899 * stack.c (print_frame_info): Use as variable.
1900 * defs.h (lines_to_list): Remove declaration.
1902 Mon Sep 9 13:45:57 1991 John Gilmore (gnu at cygint.cygnus.com)
1904 * breakpoint.c (insert_breakpoints): Restore warning about
1905 the program might be running in another process, but only for
1906 systems with this brain death (#ifdef ONE_PROCESS_WRITETEXT).
1907 * xm-hp300bsd.h, xm-mips.h, xm-vax.h: Define it.
1909 * utils.c (error): if error_pre_print is set, print the string
1911 * main.c (main, print_gnu_advertisement, print_gdb_version):
1912 Reformat legalese so it always prints, but acts as an "I'm here"
1913 message while symbols are being read. If any errors occur,
1914 print a few newlines to set off the message and start it at the
1915 left margin. Remove mention of "help" command, and don't yak
1916 about symbol reading.
1917 (catch_errors): Error string is now printed first in case of
1919 * command.c (undef_cmd_error, lookup_cmd): On undefined command,
1920 suggest the "help" command.
1922 * Makefile.in (VERSION): Set to 4.0.2.
1924 Thu Sep 5 23:49:48 1991 John Gilmore (gnu at cygint.cygnus.com)
1926 * .gdbinit: Remove useless "rr" command. Set complaints
1927 to 1 for people debugging gdb.
1929 * breakpoint.c, remote-vx.c: Reword strings printed by
1930 catch_errors callers.
1932 Wed Sep 4 11:07:50 1991 John Gilmore (gnu at cygint.cygnus.com)
1934 * WHATS.NEW: "history write -> history save". Doc "write on/off".
1935 (Fix from kenc@viewlogic.com.)
1937 Fix some infrastructure to be able to cope with host and target
1938 machines with different sized basic types (ints, ptrs, etc).
1939 (Idea from pierre@la.tce.com (Pierre Willard).)
1941 * values.c (value_from_longest): Rename from value_from_long.
1942 Handle pointer types as well as integers, so that targets with
1943 different pointer sizes from the host can be accomodated.
1944 * breakpoint.c, convex-tdep.c, eval.c, expprint.c, printcmd.c,
1945 valarith.c, valops.c, valprint.c, value.h, values.c: Rename
1946 uses of value_from_long to value_from_longest.
1947 * eval.c, findvar.c, printcmd.c, valarith.c, valops.c: Pass
1948 the correct pointer type to value_from_long{est}.
1950 * doc/gdb.texinfo ($_, $__): Describe types of these variables.
1952 * remote-vx.c: Remove obsolete code for calling functions via
1953 vxworks kludge interface (it referenced value_from_long).
1955 * valops.c (value_string): Find malloc with lookup_misc_func, not
1958 Tue Sep 3 18:37:46 1991 John Gilmore (gnu at cygint.cygnus.com)
1960 Make writing to files work properly. (Fixes to BFD are also needed.)
1962 * core.c (core_open): Open file ourselves, read or r/w, depending on
1963 write_files. Use bfd_fdopenr.
1964 * gdbcore.h (write_files): New variable.
1965 * exec.c (write_files): Define variable, add set&show for it.
1966 (exec_file_command): Use write_files to open for read or r/write.
1968 Make shared library reading happen automatically. These changes
1969 are mostly from Peter Schauer <pes@regent.e-technik.tu-muenchen.de>.
1971 * inferior.h (stop_soon_quietly): Add to exported variables.
1972 * infrun.c (child_create_inferior): call solib hook, if defined.
1973 (child_attach): call solib hook, if defined.
1974 * solib.c: Include inferior.h. Add from_tty to so_list as kludge.
1975 (find_solib): Use lookup_misc_func rather than hand-rolled.
1976 (symbol_add_stub): New stub for catch_errors.
1977 (solib_add): Avoid output if !from_tty. Catch errors rather
1978 than just calling symbol_file_add and bombing.
1979 (solib_create_inferior_hook): Interface with the target process
1980 to let it read and alloc shared libs, then figure out what it did.
1982 * core.c (validate_files): Fix typo, soften warning.
1983 (Fix from Hiroto Kagotani <kagotani@cs.titech.ac.jp>.)
1985 * utils.c (fputs_demangled): Avoid duplicate printing if
1986 demangling is off. (Fix from J.T. Conklin <jtc@cayenne.com>.)
1988 * infrun.c (proceed): Cast -1 to (CORE_ADDR) before comparing.
1989 (Fix from pierre@la.tce.com (Pierre Willard).)
1991 * main.c (catch_errors): Change argument to a char * from an int,
1992 since a char * can point to a struct full of glop, but an int
1993 is not guaranteed to be able to hold a pointer.
1994 * breakpoint.c (breakpoint_cond_eval, bpstat_stop_status,
1995 breakpoint_re_set_one, breakpoint_re_set): Adapt.
1996 * core.c (core_open, solib_add_stub): Adapt.
1997 * remote-vx.c (symbol_stub, add_symbol_stub, callers): Adapt.
1999 Wed Aug 28 18:18:05 1991 John Gilmore (gnu at cygint.cygnus.com)
2001 * Makefile.in: Update VERSION to 4.0.1. Evade GNU Make bug
2002 by adding .NOEXPORT target.
2004 Fri Aug 23 17:14:25 1991 John Gilmore (gnu at cygint.cygnus.com)
2008 * Makefile.in (VERSION): Roll to 4.0.
2009 (gdb.tar.Z): Make refcard.ps as well, for shipment.
2011 Fri Aug 23 14:07:09 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
2013 * doc/gdb.texinfo: minor rewordings, crossref to ptype from print,
2016 * doc/Makefile, Makefile.in: generate "gdb-all.texi" rather than
2019 * doc/rdl-apps.texi: renamed from rdl-apps.texinfo
2021 * Makefile.in, doc/Makefile, doc/.Sanitize, doc/gdb.texinfo:
2022 reflect above name change
2024 * WHATS.NEW: correct pointer to refcard.
2026 * doc/gdb.texinfo: update New Features, Installing
2028 * doc/gdbint.texinfo: add short description of configure +template
2030 Fri Aug 23 11:46:08 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
2032 * doc/gdb.texinfo: update, fix bugs in "Installing" appendix
2034 Fri Aug 23 01:02:00 1991 John Gilmore (gnu at cygint.cygnus.com)
2036 * Makefile.in: Add config.sub, make doc/rdl-apps.texinfo for
2037 tar file, add dependencies for referenced doc files.
2039 Thu Aug 22 22:17:06 1991 Stu Grossman (grossman at cygint.cygnus.com)
2041 * coffread.c, symfile.c, stack.c: saberized.
2043 Thu Aug 22 16:20:27 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
2045 * doc/refcard.tex: permuted Essential Commands sec
2047 * doc/gdb.texinfo: new C++ chapter; revised installation appendix;
2049 set/show symbol-reloading
2050 default set complaints 0
2052 RET-repeat disabled after prompted long displays
2053 processID (attach) interpretation of 2nd GDB cmdline arg
2055 Thu Aug 22 14:05:47 1991 Stu Grossman (grossman at cygint.cygnus.com)
2057 * expread.y, coffread.c, dbxread.c, target.c, mem-break.c,
2058 cplus-dem.c, values.c, valprint.c, symfile.c, remote.c,
2059 breakpoint.c, main.c: lint.
2061 Thu Aug 22 02:02:26 1991 John Gilmore (gnu at cygint.cygnus.com)
2063 Install new configuration scheme for GDB and friends.
2065 * config.sub: Translate ordinary names to three-part names.
2066 * configure: Use three-part names internally.
2067 * configure.in: Translate three-part names to filenames.
2069 * README, WHATS.NEW: Update for gdb-4.0.
2070 * Makefile.in: Roll VERSION to 3.99.
2072 Wed Aug 21 18:21:09 1991 John Gilmore (gnu at cygint.cygnus.com)
2074 * infptrace.c (KERNEL_U_ADDR_BSD): Include a.out.gnu.h.
2075 * i960-tdep.c, m68k-tdep.c, sparc-tdep.c, tm-i960.h,
2076 tm-m68k.h, remote-nindy.c: Change ext_format_XXX structs
2077 to single structures rather than arrays; when passing
2078 their address, use &. This avoids trouble with bdead compilers.
2079 * mcheck.c: Don't include <stdlib.h>; just declare "void abort();"
2080 instead. This avoids portability headaches.
2081 * mips-tdep.c (mips_do_registers_info): Only print FP regs if
2083 * source.c (open_source_file): Avoid ANSI const bdeath by
2084 skipping declaration and then casting result value.
2085 * tm-hp300bsd.h: Clarify comment.
2086 * utils.c (strstr): Result is const char *; ANSI bdeath.
2087 * xm-hp300bsd.h: Define HOST_BYTE_ORDER. Redefine INT_MIN,
2088 since system include file defines it differently from "defs.h",
2089 though the two are equivalent for our purposes.
2090 * tconfig/hp300bsd: Add m68k-tdep.o.
2092 Tue Aug 20 16:01:11 1991 John Gilmore (gnu at cygint.cygnus.com)
2094 * tconfig/sun*4: Remove warnings about system assembler.
2096 Mon Aug 19 13:44:46 1991 John Gilmore (gnu at cygint.cygnus.com)
2098 * mcheck.c: Avoid warning about undeclared abort fn.
2099 * tm-sparc.h (PC_ADJUST): Avoid calling error() from this;
2100 it causes recursive calls to error() when used in cleanups.
2101 To do so requires that we make it a function, so we do.
2102 * sparc-tdep.c (sparc_pc_adjust): New implem of PC_ADJUST.
2103 * utils.c (do_cleanups): Remove the current cleanup from the
2104 chain *before* calling it, in case error() is called from it.
2105 The result won't be pretty, but won't be an infinite loop either.
2107 Mon Aug 19 00:41:04 1991 Michael Tiemann (tiemann at cygint.cygnus.com)
2109 * dbxread.c (read_struct_type): Grok anon structs for C++.
2110 (vb_name, vptr_name): Null terminate these strings.
2112 Fri Aug 16 08:31:03 1991 John Gilmore (gnu at cygint.cygnus.com)
2114 Minor bug fixes from BSD Net2 gdb:
2116 * blockframe.c (get_prev_frame_info): If FRAME_CHAIN_COMBINE
2117 returns 0, there is no previous frame.
2118 * breakpoint.c (commands_command): If !from_tty, don't call
2119 input_from_terminal_p().
2120 * dbxread.c (record_misc_function): Speed up slightly.
2121 (compare_psymbols): Ditto.
2122 * infcmd.c (do_registers_info): Take a second argument to
2123 determine whether to print float registers. "info registers"
2124 does not do so anymore. "info all-registers" does, now.
2125 * mips-tdep.c, pyr-tdep.c (xxx_do_registers_info): Take second
2127 * tm-mips.h, tm-pyr.h (DO_REGISTERS_INFO): Pass second arg.
2128 * inflow.c (initialize_inflow): Set tflags_ours correctly.
2132 * breakpoint.c (bpstat_do_actions): Use a cleanup to restore
2133 executing_breakpoint_commands if we are interrupted by error.
2134 * coffread.c (init_lineno): Avoid problem with zero-sized linetab
2135 versus malloc/free. From: john@labtam.labtam.oz.au (John Carey).
2136 * core.c (solib_add_stub, core_open): Call SOLIB_ADD inside a
2137 catch_errors() so we can setup the frame regardless of whether
2138 the shared libs work.
2139 * ieee-float.c (double_to_ieee_extended): Get exponent from
2140 right place in little-endian systems. From John Carey.
2142 Thu Aug 15 18:43:57 1991 John Gilmore (gnu at cygint.cygnus.com)
2144 * main.c: Remove unused terminating_signals and catch_termination().
2145 (long_options): Terminate with a zero element.
2146 [Bugfix from Atsuo Kawaguchi <atsuo@hark86.harl.hitachi.co.jp>.]
2147 (gdb_readline): Make call-compatible with readline.
2148 (init_signals): Improve comments re vfork vs. signal.
2150 * utils.c (prompt_for_continue): Use new gdb_readline().
2151 If we prompt for continuation, we don't let CR repeat the previous
2152 command, once we get back to a prompt. It's too easy to keep
2153 hitting CR, expecting "--more--" prompts, and have some long
2154 command start repeating on you.
2156 Tue Aug 13 16:17:56 1991 John Gilmore (gnu at cygint.cygnus.com)
2158 * blockframe.c (frameless_look_for_prologue): Speed up by
2159 calling SKIP_PROLOGUE_FRAMELESS_P if it's defined.
2160 * tm-sparc.h (SKIP_PROLOGUE, SKIP_PROLOGUE_FRAMELESS_P):
2161 Define two variants, one faster.
2162 * sparc-tdep.c (sparc_frame_chain): Use target_read_memory
2163 and return zero, rather than giving an error.
2164 (setup_arbitrary_frame): Initialize the PC in the new frame.
2165 (skip_prologue): Add a second arg saying whether we're just
2166 checking for a frameless function or not.
2168 * core.c (core_open, core_close, core_xfer_memory): Move
2169 section table pointers and bfd* into the target_ops.
2170 (core_open): Allow errors in shared lib reading, etc.
2171 (core_files_info): Describe shared library sections.
2173 * exec.c (exec_open, exec_close, exec_xfer_memory, xfer_memory,
2174 exec_files_info, set_section_command): Move section table
2175 pointers and bfd* into the target_ops.
2176 (add_to_section_table): Add BFD to section table.
2178 * target.c (target_xfer_memory, target_info): Pass target to
2179 xfer_memory and target_info functions.
2182 * gdbcore.h: Move struct section_table.
2183 * target.h: New home of struct section_table.
2185 * solib.c (solib_add): New argument is the target_ops whose
2186 section list is to be added to, if any. Reallocate the
2187 sections in that target to add any that come from shared libs.
2188 (throughout) so_sections renamed to sections.
2189 (solib_xfer_memory): Deleted.
2190 * tm-sunos.h (SOLIB_ADD): Add target argument.
2191 (SOLIB_XFER_MEMORY): Delete.
2193 * core.c, exec.c, inftarg.c, remote-eb.c, remote-nindy.c,
2194 remote-vx.c, remote.c, target.c, target.h: Remove add_syms vector
2195 from target_ops. It's the same on all targets. Add two section
2196 pointers to target_ops.
2198 * stack.c (find_relative_frame): Dump ancient algorithm for
2199 "down", just use handy "next" pointers.
2200 (frame_command): Don't error if there is no stack; let user
2203 * inflow.c (new_tty_prefork, new_tty): New prefork routine
2204 modifies static state in the parent process; new_tty itself
2205 runs in the child and modifies the child's file descriptors
2206 to match the saved static state.
2207 * infrun.c (child_create_inferior): Call new_tty_prefork,
2210 * infptrace.c (child_xfer_memory): Add ignored target arg.
2211 * remote-eb.c (eb_xfer_inferior_memory): ''
2212 * remote-nindy.c (nindy_xfer_inferior_memory): ''
2213 * remote-vx.c (vx_xfer_memory): ''
2214 * remote.c (remote_xfer_memory): ''. Rename from
2215 remote_xfer_inferior_memory.
2217 * main.c (main): Only try to attach "corefile" argument if
2218 it starts with a digit.
2220 * symfile.c (symbol_reloading): New "set/show" variable.
2221 (symbol_file_add): Shorten message about symbol reading.
2222 (add_symbol_file_command): Merge with add_syms_addr_command,
2223 since this should work on all targets now.
2224 (stop_whining): Default to zero, to shut up complaints
2225 about bad symbol tables on many systems.
2226 (free_named_symtabs): Just exit unless symbol_reloading.
2228 * xm-sun3os4.h, xm-sun4os4.h: Define BROKEN_LARGE_ALLOCA,
2229 and add comment explaining shared library screw.
2231 * source.c: #if defined => #ifdef.
2233 Thu Aug 8 12:23:19 1991 John Gilmore (gnu at cygint.cygnus.com)
2235 * doc/gdbint.texinfo: Improve doc on porting to new OS's.
2237 Tue Aug 6 17:16:15 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
2239 * doc/rdl-apps.texinfo: provide default readline-appendix finder
2240 (doc/Makefile knows how to make one for local config)
2242 * Makefile.in: use doc/Makefile for doc targets
2244 * doc/Makefile: GDB documentation now has its own Makefile
2245 doc/refcard.tex: renamed from "gdbrc.tex"
2246 doc/.Sanitize: add Makefile; recognize renamed refcard.tex
2247 doc/gdbint.texinfo: add markup in "Cleanups" chapter
2250 Fri Aug 2 00:13:06 1991 John Gilmore (gnu at cygint.cygnus.com)
2252 * values.c (baseclass_addr): When reading target memory, use the
2253 length of the basetype, not the upper type. We've only malloc'd
2254 enough space for the basetype, leading to errors in free().
2256 * expprint.c (print_subexp): Print UNOP_MEMVAL of an OP_LONG that
2257 ends up as a function specially, since we know the actual type of
2258 the pointed-to address. This (somewhat) fixes display of
2259 expressions that include misc_function_vector names. Try `cond 1
2260 !strcmp("a","b")' then `i b'.
2262 * infrun.c: Move DO_DEFERRED_STORES from proceed() to resume().
2263 The child can be proceeded from inside wait_for_inferior in
2264 evaluating breakpoint conditions, and DO_DEFERRED_STORES was
2265 getting skipped in that case.
2267 * expprint.c (print_subexp): Use filtered output, since the
2268 subroutines we call use it, otherwise the output is horribly
2269 mangled, since output of wrappable stuff comes out late.
2271 * Makefile.in: Bump VERSION to 3.98.1
2273 * infrun.c (child_create_process): Use execlp to find the
2274 shell to exec our target program. This requires some fiddling
2275 with `environ' since there is no execlpe().
2277 Thu Aug 1 15:35:17 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
2279 * Makefile.in, doc/gdbrc.tex, doc/rc-* (new files):
2280 Minor rearrangement of refcard permits two new make targets--
2281 gdbrc.dvi DVI output for refcard, using CM fonts
2282 gdbrc.ps PostScript refcard, using PS fonts
2284 Wed Jul 31 16:46:21 1991 John Gilmore (gnu at cygint.cygnus.com)
2288 * TODO, Projects, WHATS.NEW, README: Update for gdb-3.98.
2289 * Makefile.in (gdb-all.texinfo): Avoid touching file if M4 dies.
2291 Wed Jul 31 16:35:58 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
2293 * doc/gdb.texinfo: last changes for release.
2294 Minor typo and formatting fixes; incorporated most fixes remaining from
2295 filed mail commenting on earlier drafts.
2297 Added warnings: pipes don't work in run command;
2298 conditions are converse of assertions;
2299 step over fn without debug info goes to next fn;
2300 vars may have "wrong" values near fn entrance, exit
2302 Added example from Kingston on printing repeated nonadjacent values
2304 Added explicit mention that in Emacs gdb mode C-c and C-z are like
2305 shell mode for signals
2307 Renamed "Stepping and Continuing" to "Continuing and Stepping" so it
2308 doesn't sound so much like its parent "Stopping and Continuing"; also
2309 moved entries on continue to top of section, so they don't get lost.
2311 Improved installation directions in appendix, added manual formatting
2314 Tue Jul 30 17:26:39 1991 John Gilmore (gnu at cygint.cygnus.com)
2316 * configure.in: Remove xm.h and tm.h even if we aren't linking
2317 new ones, so "./configure sun4; ./configure none" does the right
2318 thing. Assume that alldeps.mak and depend are already built in
2319 srcdir, and avoid running "make" (particularly "make depend",
2320 which involves "gcc") from inside configure. Build Makefile
2321 directly rather than building Makefile.conf first.
2322 * configure: Regenerate with above changes.
2323 * Makefile.in: Use $(BISON) to find bison. Roll VERSION
2324 to 3.98. Revise gdb.tar.Z procedure to produce a file
2325 called gdb-$(VERSION).tar.Z but which unpacks into a
2326 directory called "gdb". Move non-source files out of
2327 $(SFILES_SUBDIR). Pretty up alldeps.mak with comments.
2328 (depend): Don't try to do "gcc expread.y".
2329 (expread.o): Update dependencies by hand.
2331 Mon Jul 29 15:21:09 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
2334 Fixed a variety of small typos that prevented info from formatting
2335 cleanly; altered too-long heading for GPL Appendix, as discussed
2336 w/RMS; Changed date on cover to July 91.
2338 Fri Jul 26 13:20:02 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
2341 (1) Applied some fixes due to comments from Larry Breed (easier ones
2342 through chapsec 5.2)
2343 (2) Eliminated use of @footnote---had my doubts about it anyways, and
2344 it's broken in latest texinfo
2345 (3) Introduced *some* use of [] for optional arguments, where
2346 explanation is not simpler by listing cmd w arg and cmd w/out arg
2347 separately. Still not using @deffn.
2348 (4) Dropped in GPL-2. NOTE: one of GPL-2 or texinfo is broken; a
2349 couple of headings are too long. Need patches to texinfo or revision
2352 * Partial update to README (which still needs work for this
2353 release!): (1) use of configure corrected for new script,
2354 (2) "make gdb.dvi" and "make gdb.info" mentioned.
2356 Wed Jul 24 06:44:02 1991 John Gilmore (gnu at cygint.cygnus.com)
2358 * symtab.c (lookup_symbol): Don't complain right off about
2359 no debug symbols; use the misc function vector first.
2360 (list_symbols): Use misc function vector to find symbols
2361 that don't have debug info, and print them.
2362 (find_pc_symtab): Temporarily avoid fatal() when psymtab
2363 PC range doesn't match symtab PC range, as it does on the
2364 MIPS because our symtab reading isn't perfect.
2366 * dbxread.c (dbx_symfile_read): Make warning about
2367 "no debug symbols" slightly nicer.
2369 * source.c (select_source_symtab): If "main" symbol exists,
2370 but decode_line_spec can't find line info, don't just return
2371 a zero; try other source symtabs or give an error.
2373 * mipsread.c (parse_partial_symbols): Sort the psymtabs by
2374 their low addresses first, then rip through fixing high addrs.
2376 * ns32k-opcode.h (sfsr): Bugfix from Rune Nerg}rd,
2377 <runene@ifi.uio.no>.
2378 (NS32K_SVC_IMMED_OPERANDS): Reverse the #ifndef.
2380 Tue Jul 23 18:52:43 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
2382 * Minor, mostly mechanical, cleanup of doc subdir for clean
2383 makeinfo'ing and TeXing; also ensured gdb-all.texinfo (post-m4)
2384 and gdb.info (post- texinfo2 makeinfo) generated for distribution.
2386 Sun Jul 21 03:54:52 1991 John Gilmore (gnu at cygint.cygnus.com)
2388 Mostly MIPS and general symbol-reading fixups.
2390 * doc/gdbint.texinfo: Add documentation on symbol-reading
2393 * mipsread.c: Remove kludges around #include "ecoff.h".
2394 Remove redefinitions of a_magic, etc, no longer used.
2395 (parse_symbol, ): Convert "Internal:" printfs to complain()ts.
2396 Fix global overview comments to match symfile.c protocol.
2397 (mipscoff_new_init): Eliminate cur_hdr if we have one.
2398 (mipscoff_symfile_read): Eliminate unused code. Avoid
2399 sorting all the symtabs, when all we have read here is psymtabs.
2400 The symtabs are sorted as they are created anyway. Tell
2401 condense_misc_bunches whether we're mainline.
2402 (psymtab_to_symtab_1): Pass filename when recursing, to make
2403 stack trace more informative.
2404 (parse_partial_symbols): Assume cur_hdr as argument.
2405 (read_mips_symtab): Don't clobber cur_hdr, so it can be freed.
2406 Pass cur_hdr implicitly to parse_partial_symbols. Avoid checking
2407 the TYPE_NAME of char *, since that's done in symfile.c.
2408 (free_numargs, parse_symbol, add_symbol, add_block,
2409 shrink_linetable): Declare these fns void.
2410 (upgrade_type): Convert tree of if's to switch. Clean up
2411 bogus "off == 0" handling with a complaint. Avoid setting
2412 field bitpos and bitsize of array with lower and upper bounds.
2413 Check specified bitsize of elements against their actual type's
2414 bitsize, and complain if different. Complain about unknown
2416 (parse_fdr): Don't assume sizeof(char *) == sizeof (struct *).
2417 (psymtab_to_symtab_1): Print names of subsidiary files that
2418 are being read in. FIXME, we read far too many files. This code
2419 is not the problem, the problem is in parse_fdr where the psymtabs
2421 (cross_ref): Result should indicate that we used one aux entry
2422 normally, or two if we encountered a "next" entry. This used
2423 to leave the caller pointing at the wrong aux entry.
2424 (add_symbol): If overflowed cur_block, reallocate it larger,
2425 chase all pointers to it, and complain(), rather than clobber memory.
2426 (shrink_block): Use xrealloc rather than xmalloc-and-copy.
2427 (new_field): Only allocate one field initially, not two.
2428 Pull ++ out of macro argument. Simplify.
2429 (_initialize_mipsread): Avoid initialization of importd
2430 global_psymbols and static_psymbols.
2432 * symfile.c (psymtab_to_symtab): Depend on XXX_psymtab_to_symtab
2433 to properly set pst->symtab; avoid searching for it.
2434 (symfile_fns): Improve comments, add a FIXME.
2435 * dbxread.c: Update comments to reflect symfile protocol.
2436 (read_ofile_symtab, end_symtab): Return the symtab.
2437 (psymtab_to_symtab_1): Set pst->symtab.
2439 * coffread.c (coff_symfile_read): tell condense_misc_bunches
2440 whether we're mainline.
2442 * symfile.h (sym_fns): Remove unused sym_discard member.
2443 * coffread.c, mipsread.c, dbxread.c: Remove XXX_symfile_discard.
2445 * mtrace.c (mtrace): Take effect if mallwatch is set, even if
2446 the environment variable is not.
2447 * infcmd.c (finish_command): Use filtered printfs.
2448 * cplus-dem.c: Add struct tags to a few unnamed structs.
2449 * valops.c (value_coerce_array): Improve comments.
2450 * valprint.c (type_print_varspec_suffix): Print array size only
2451 if greater than zero.
2452 * m88k-tdep.c: Shift some lines left by one space, that had
2453 apparently been trashed at some point.
2454 * TODO: More things to do, a few got done.
2456 Thu Jul 18 22:46:05 1991 John Gilmore (gnu at cygint.cygnus.com)
2458 * symtab.h (LOC_EXTERNAL): Eliminate in favor of LOC_STATIC.
2459 (ldsymoff, ldsymlen, globals_offset, statics_offset): Improve
2461 * dbxread.c (read_dbx_symtab): LOC_EXTERNAL -> LOC_STATIC.
2462 * expread.y, findvar.c, symmisc.c: Ditto.
2463 * printcmd.c (address_info): Update printed forms of LOC_
2464 symbols. Elim LOC_EXTERNAL.
2465 (print_frame_args): Keep track of param stack offsets before
2466 re-looking up to find the local register param is kept in.
2468 * mipsread.c: Use <symconst.h> and <sym.h> rather than <syms.h>.
2469 Further integration of mipsread into gdb. Eliminate unused
2470 routines, duplicate declarations. Handle static symbols in
2471 psymtabs as well as external symbols. When reading symtabs,
2472 insert symbols into the correct block (global, static, or a local
2474 (read_mips_symtab, parse_partial_symbols): Don't pass useless
2476 (mipscoff_symfile_read): Don't call select_source_symtab.
2477 (parse_symbol): Use SYMBOL_VALUE_ADDRESS where appropriate,
2478 rather than SYMBOL_VALUE.
2479 (parse_external): Comment clobbering of top_stack.
2480 (parse_partial_symbols): Update comments. Allocate and parse
2481 static symbols as well as external symbols. FIXME, enum values
2482 are not handled in this pass, but should be. Inline new_psymbol.
2483 Use SYMBOL_VALUE_ADDRESS.
2484 (psymtab_to_symtab_1): Read symbols into global static block
2485 by default (until enter some function's local block context).
2486 (sort_blocks): Clean up STATIC_BLOCK as well as GLOBAL_BLOCK.
2487 (destroy_all_symtabs, new_psymbol): Eliminate, unused.
2489 * source.c (select_source_symtab): Select a source symtab
2490 from either the symtabs or, failing that, the psymtabs.
2491 (list_command): Update error message.
2492 (forward_search_command, reverse_search_command): Use getc, not
2493 fgetc, for speed. FIXME, add comment about buffers that die if
2494 overrun by long line.
2496 * values.c (unpack_field_as_long, modify_field): Avoid shifting
2497 by an entire word, which is not portable, if we have a 32-bit
2498 field. (Code in dbxread.c already turns such bitfields, if
2499 aligned, into ordinary ints, but fixing this will help for other
2500 symbol formats and for future changes.)
2501 * core.c (core_open): Handle ANSI const brain death.
2502 * utils.c (vprintf): Fix varargs typo.
2504 Sun Jul 14 00:42:53 1991 John Gilmore (gnu at cygint.cygnus.com)
2506 * findvar.c (find_var_value): Handle &function better.
2507 * TODO: Document work needed on &fn and &array.
2508 * printcmd.c (print_address_symbolic): New arg is the prefix
2509 to print if a name is printed.
2510 (print_address_demangle): Honor "set print address" now.
2511 Use new arg above to improve spacing of output.
2512 * valprint.c (val_print): When printing function pointers,
2513 print symbolic form too.
2514 * breakpoint.c (breakpoint_1): Use new print_address_symbolic.
2516 Mon Jul 8 19:02:46 1991 John Gilmore (gnu at cygint.cygnus.com)
2518 * core.c (memory_error): Reword error msg to mislead less.
2520 * mips-pinsn.c (print_insn_arg 'd'): Print $ with reg name.
2522 * mipsread.c (read_mips_symtab, read_the_mips_symtab,
2523 parse_partial_symbols): Use newer BFD internals (external_filehdr
2524 and external_aouthdr), byte-swap the fields that we care about
2525 before using them, and make the file header data local to
2526 read_the_mips_symtab rather than global.
2528 Sat Jul 6 01:34:15 1991 John Gilmore (gnu at cygint.cygnus.com)
2530 * ns32k-opcode.h (movmw, movmd): Fix opcodes. Bug fix
2531 from Rune Nerg}rd <runene@ifi.uio.no> on 5 Jul 1991.
2533 * main.c (command_line_input): Flush stdout and stderr
2534 before every call to readline. This reportedly fixes a bug
2535 that comes up in Sys V running emacs-gdb and/or xxgdb,
2536 when stdin/out are pipes or sockets.
2538 Thu Jul 4 14:47:06 1991 John Gilmore (gnu at cygint.cygnus.com)
2540 * configure.in, Makefile.in: Avoid rebuilding "depend" as much.
2541 Avoid declaring Makefile dependencies, because GNU Make stupidly
2542 tries to update it if we do.
2544 * coffread.c: Revise for minor changes to bfd internal coff
2547 * configure: If -template= is given a relative path, make it
2548 absolute before recurring in subdirectories.
2550 * configure, configure.in, Makefile.in: Install "configure" script
2551 as replacement for config.gdb.
2552 * config.gdb, Makefile.dist, Makefile.sdir: Remove
2553 * README: Update for configure, mostly. FIXME.
2555 * Add dec3100 as equivalent to littlemips. Indicate in all host &
2556 target config files that they are for the host. When the lines
2557 get copied into the Makefile, this makes it more obvious what's
2560 Mon Jun 24 23:49:07 1991 John Gilmore (gnu at cygint.cygnus.com)
2562 * sparc-opcode.h (trap opcodes): Avoid leading spaces or
2563 tabs, which end up in the disassembler output inadvertently.
2565 Wed May 29 23:01:03 1991 John Gilmore (gnu at cygint.cygnus.com)
2567 Make it compile cleanly in an ANSI GCC2 environment.
2569 * blockframe.c: <stdio.h>
2570 * cplus-dem.c: free takes a void *, ifdef __STDC__
2571 * dbxread.c (read_huge_number): avoid gcc2 bug hoisting calc of
2573 * defs.h (alloca): Avoid doing anything if alloca already def'd.
2574 * stddef.h, stdlib.h: Remove these files.
2575 * symtab.c: Avoid declaring qsort, close.
2576 * symfile.c: Avoid declaring close.
2577 * utils.c (vprintf): Declare "ap" arg as proper va_alist.
2578 * sparc-tdep.c: Avoid including lots of Sun-host-specific files.
2580 Assorted other changes.
2581 * dbxread.c: include "libaout.h", not "liba.out.h".
2582 * printcmd.c (print_frame_args): Set recurse properly for
2583 indentation of struct and array parameters.
2584 * valops.c (value_cast): Allow cast to void.
2585 * infrun.c (resume): If NO_SINGLE_STEP, call machine dependent
2586 single_step() in a target-independent fashion.
2587 * sparc-tdep.c (single_step): Don't call ptrace ourselves, just
2588 set up to be ready to continue. This makes us target independent.
2589 * infptrace.c (child_resume): Remove call to single_step; now
2590 can single step a SPARC target of any kind.
2592 Wed May 22 18:18:24 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
2594 * Makefile.dist, doc/gdb.texinfo, doc/*-m4.texinfo: split up GDB
2595 docn into separate sections---basically chapters, plus two loose
2596 pieces that can be configured to go in different places. This
2597 allows GNU m4 to preprocess the manual without coredumping.
2599 * Makefile.dist: tell TeX where to find texinfo.
2601 Mon May 20 12:15:04 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
2603 * Makefile.dist, doc/gdb.texinfo: respectively create, and use,
2604 the new target "rdl-apps.texinfo" which captures the Makefile
2605 variable that records where to find the Readline libraries.
2607 Sun May 19 05:36:59 1991 John Gilmore (gnu at cygint.cygnus.com)
2609 * tahoe-pinsn.c: #include "tahoe-opcode.h", not "opcode.h".
2610 * tm-tahoe.h (FIX_CALL_DUMMY): Ignore more parameters.
2611 * defs.h (const, volatile): Only define if not already defined.
2612 * Makefile.dist (gdb.tar.Z): Create doc subdir w/out CVS/RCS crud.
2614 * README: Update for release 3.95.
2615 * config.gdb: Don't create readline dir in subdir builds.
2616 * main.c: Include with "..." form for non-system include files,
2617 so "gcc -MM" for "make depend" works.
2618 Include readline files with "...h" rather than <readline/...h>.
2619 * mipsread.c: Include "ecoff.h" rather than "intel-coff.h".
2621 * coffread.c: Undo minor damage done by Rich Pixley. Use
2622 different internal and external representations of COFF
2623 data structures. Use new BFD routines for swapping them in and
2625 * symfile.c (free_named_symtabs): Avoid freeing file names that
2626 are null or empty. Old i960 tools seem to produce files that
2627 claim to have empty names, causing each successive file read
2628 to blow away the previous one.
2629 * sparc-xdep.c (deferred_stores): Repair minor damage by Rich.
2630 Move deferred_stores to top of file, but don't separate its
2631 #define's from its variable. Add commentary.
2632 * Makefile.dist: Fix Rich damage; undo "configure" changes in
2633 favor of keeping the (working) config.gdb. Move readline
2636 Fri May 17 12:49:56 1991 Per Bothner (via gnu at cygint.cygnus.com)
2638 * dbxread.c (read_struct_type): Try to handle g++ version 1 MI
2640 * infptrace.c (fetch_registers): no result, since now void.
2641 * tconfig/news: target depends on m68k-tdep too.
2643 Fri May 17 14:40:14 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
2645 * Makefile.dist: added readline/inc-*.texinfo to dependencies for
2648 * readline/inc-history.texinfo, readline/inc-readline.texinfo:
2649 applied various small fixes due to or inspired by RMS comments
2651 * doc/gdb.texinfo: finished using all RMS comments, save those for
2652 appendices on readline and cmd history (which are in other source
2655 Thu May 16 18:06:05 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
2657 * doc/gdb.texinfo: (1) Updated w/ref to RMS comments through
2658 chapter 9; (2) documented 'break' command's menu mode for
2659 overloaded names, in response to hgs problem report C++ p-31
2661 Wed May 15 11:02:48 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
2663 * doc/gdb.texinfo: (1) better introductory example; (2) more
2664 consistent use of @code, @samp, @file, @kbd throughout; small
2665 cleanups to first three nodes; (3) new "Contributors" node;
2666 (4) Appendix, Renamed Commands; (5) divert specialized startup
2667 instructions to "Targets" chapter for generic manuals, while
2668 leaving them up front for manuals specific to specialized
2669 environments; (6) apply fixes from RMS comments through chapter 4.
2671 * pretex.m4: modify explanatory text slightly (and redefine
2672 "regexp") to keep GNU m4 from complaining. (It still crashes
2673 later, but one step at a time...)
2675 Wed May 15 10:32:12 1991 John Gilmore (gnu at cygint.cygnus.com)
2677 * readline/readline.c (update_line): Avoid dereferencing a pointer
2678 before comparing it to its bounds. Saber caught this.
2679 (init_terminal_io): Don't set BC from the "pc=" termcap variable,
2680 and only set PC if tgetstr returned non-null. Saber caught this.
2682 Tue May 14 16:29:53 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)
2684 * Makefile.dist: put gdb.dvi stuff (updated to use M4 preprocessor
2685 stuff for config manual) here where it counts; updated
2686 to use new subdir structure (gdb/doc/).
2688 * Makefile: generated from above via
2692 * gdbint.texinfo: added instructions on generating gdb.info* files
2693 locally for release. These are ordinary info
2694 files, formatted from gdb.texinfo (via gdb-all.texinfo, see
2695 Makefile)---but due to use of texinfo 2, can't count on makeinfo
2696 to generate these, so we distribute them already formatted.
2698 * gdb.texinfo: included full Info node and menu crud (as generated
2699 by C-u M-x texinfo-master-menu using the texinfo-2 elisp code).
2701 * Makefile: updated "gdb.dvi" target to use M4 preprocessor;
2702 put in comments-for-future gdb.info target (one day makeinfo will
2705 Tue May 14 13:51:36 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)
2707 * gdb.texinfo: Updated to include new or old undocumented
2708 commands, at least the following (perhaps some others I forgot to
2709 record): info f, info float, info path, info program, info s, info
2710 set, info source, info terminal, info types, info user, set/show
2712 Also covered all recent GDB command renames for v4.
2714 Mon May 13 14:57:46 1991 John Gilmore (gnu at cygint.cygnus.com)
2716 * mipsread.c: Rather than keeping count of how many symtabs
2717 and psymtabs we have, for sorting purposes, count them when
2718 we need to sort. This fixes bug in rereading of symbol tables.
2720 Fri May 10 15:43:33 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)
2722 * infcmd.c: renamed "info path" to "show paths"

2736 * coffread.c, exec.c, infptrace.c, inftarg.c, remote.c, solib.c,
2737 symtab.h, target.c, target.h: Lint.
2738 * core.c: setup and select frame after reading shared libs,
2739 else reading shared libs will clobber them. Lint.
2740 * utils.c (error): Force out any buffered wrap text.
2742 Fri May 3 22:01:56 1991 John Gilmore (gnu at cygint.cygnus.com)
2744 * remote.c: Remove decls of memory_insert_breakpoint
2745 and memory_remove_breakpoint, no longer used. (Suggestion of
2748 * Makefile.dist: use ${subdir} in paths of BFD and LIBIBERTY,
2749 to make it easier to interface to "configure"'d libraries.
2751 Fri May 3 13:10:01 PDT 1991 Roland Pesch (pesch at fowanton.cygnus.com)
2753 * valprint.c: introduce "set p", "set pr", "show p" and "show pr" as
2754 aliases for set/show print.

2810 * coffread.c [TDESC]: Move setting of debug_info from
2811 coff_symfile_read to find_linenos and make it work with BFD.
2813 * cplus-dem.c [__STDC__]: Make x{m,re}alloc return void*.
2815 * signame.c: Cast const char* to char* when assigning to sys_siglist.
2817 * utils.c (strsave): Make arg const char* not char*.
2819 * infrun.c (wait_for_inferior) [SHIFT_INSN_REGS]: Use

2843 * infptrace.c (PT_WRITE_D, PT_READ_D): Use correct values.
2844 (This still doesn't seem to make MIPS bkpts work.)

2846 (symbol_file_command, add_file_command): Remove, obsol.
2847 * printcmd.c (ptype_command): Say "an enum" rather than "a enum".
2848 Wrap output appropriately.

2850 selected_frame rather than target_has_stack or coredumping.
2851 * valprint.c (type_print_varspec_suffix): Wrap "ptype" output of
2852 enums appropriately.
2854 Wed May 1 14:10:22 1991 Jim Kingdon (kingdon at cygint.cygnus.com)

2858 * cplus-dem.c: Include defs.h and param.h.
2859 Makefile.dist: Don't hack in the "param.h".

2863 can have both ints and enum type_pieces in it.
2864 ({push,pop}_type_int): New functions.
2866 Tue Apr 30 13:18:58 1991 Jim Kingdon (kingdon at cygint.cygnus.com)

2878 symtab.c, cplus-dem.c, value.h, expread.y, valprint.c,
2879 copying.awk, solib.c, inflow.c, symmisc.c
2880 : Lint. Use read_memory not read_memory_integer on CORE_ADDR's.
2881 Use {value_as,unpack}_pointer (added to values.c)
2882 not {value_as,unpack}_long on CORE_ADDR's.
2883 Use longest_to_int (added to defs.h) instead of cast to int.
2884 Remove from_tty arg to mod_path.
2885 Put symfile_bfd in {coff,dbx}read.c not symfile.h.
2886 Use OP_NULL instead of 0 where dummy enum exp_opcode needed.

3369 Thu Apr 4 10:09:35 1991 John Gilmore (gnu at cygint.cygnus.com)
3371 * tm-i386v.h (FLOAT_INFO): Don't define it, since the code
3372 for printing the float info is host-dependent, not
3373 target-dependent. FIXME.
3374 * i386-pinsn.c: Move #includes to top, remove useless ones.
3375 * i386-tdep.c: Don't bother including <.../reg.h> since we
3376 don't use it (and it doesn't exist on host systems).
3378 * ieee-float.c (ieee_extended_to_double): Convert NaN to Inf.
3379 Convert negative numbers properly.
3380 (ieee_test): Make numbers really random; fix format arg.
3382 * infcmd.c (attach_command, detach_command): Don't repeat on CR.
3383 * core.c (core_detach): Unpush core_ops, which might not be on
3384 top. We used to just pop the top, which broke things. Don't
3385 need dont_repeat() any more.
3386 (core_file_command): Psst! Don't repeat it.
3387 * remote-nindy.c (nindy_detach): Don't need dont_repeat() now.
3388 * expprint.c (print_subexp): Avoid switch fallthru on
3389 BINOP_ASSIGN_MODIFY, so we can print += and such.
3390 * frame.h: Fix typo.
3391 * inflow.c (kill_command): After killing inferior, print our
3392 current frame in the core file, if we have one.
3393 (generic_mourn_inferior): When inferior dies, either select
3394 the current frame (in the new target, e.g. core file), or
3395 set both the current and selected frames to NULL.
3397 Changes from Peter Schauer.
3399 * infptrace.c: Avoid <sys/ptrace.h> on USG.
3401 * Make all file names fit in 14 characters (sigh and damn!):
3402 mv hp300hpux-xdep.c hp300ux-xdep.c
3403 mv symmetry-xdep.c symm-xdep.c
3404 mv symmetry-tdep.c symm-tdep.c
3405 mv convex-opcode.h convx-opcode.h
3406 mv tm-vxworks960.h tm-vx960.h
3407 mv tm-vxworks68.h tm-vx68.h
3408 mv Makefile.srcdir Makefile.sdir
3409 mv gdb-int.texinfo gdbint.texinfo
3410 mv remote-sa.m68k.shar rem-m68k.shar
3411 mv remote-multi.shar rem-multi.shar
3412 * Makefile.dist, README, config.gdb, convex-pinsn.c,
3413 tconfig/symmetry, tconfig/vxworks960, tconfig/vxworks68,
3414 xconfig/hp300hpux, xconfig/symmetry: Change names to shorter
3417 * command.c (user_info_1, user_info): New command for listing
3418 the user-defined commands.
3420 Wed Apr 3 15:00:26 1991 John Gilmore (gnu at cygint.cygnus.com)
3422 * dbxread.c (really_free_pendings): Clear file_symbols
3423 and global_symbols after freeing them; otherwise, running
3424 this function twice (if it appears twice on the cleanup
3425 chain), we try to free things twice.
3427 * dbxread.c (read_dbx_symtab): Calculate end_of_text_addr
3428 based on text_addr (the address of text in core), not on addr (the
3429 offset between text in the .o file and in core). This change
3430 is from Peter Schauer.
3432 * main.c: Define ALL_CLEANUPS as a cast of zero.
3433 (return_to_top_level): Use it.
3434 (main): Do all cleanups after each command run as part
3435 of the gdb startup sequence. Also do all cleanups before
3436 entering the command loop, and every time we exit the command
3437 loop and reenter. Before, the cleanups from the startup sequence
3438 were being left undone until the first error!
3439 (command_loop): Rename do_nothing cleanup to command_loop_marker
3440 so we can see it easily when examining the cleanup chain.
3441 (init_signals): Add another do_nothing for signal handling.
3442 (quit_command): Only try to kill target if it has execution.
3443 Problems in the target stack got us into a state where
3444 inferior_pid was nonzero but none of the targets had execution.
3445 In this state you couldn't exit gdb.
3447 * dbxread.c: Two changes from Peter Schauer.
3448 (echo_command): Fflush output after an echo command.
3449 (show_history): Pass all args to cmd_show_list.
3451 * utils.c (init_malloc): Call mtrace to turn on tracing
3452 if the environment variable MALLOC_TRACE is set to a file name.
3453 * mtrace.c: Add source file which provides a log of every malloc,
3454 free, and realloc to a trace file.
3455 * mtrace.awk: Add source file which analyzes the trace file.
3456 * Makefile.dist (GNU_MALLOC, MALLOCSRC): Add mtrace.{c,o,awk}.
3457 (VERSION): Roll to 3.94.3.
3459 * breakpoint.c (breakpoint_1): Add a space to "i watch" output.
3460 (check_duplicates): Don't bother with watchpoints.
3461 (set_raw_breakpoint): Comment about danger of this routine.
3462 (watch_command): Parse and eval all args before calling
3465 * solib.c (find_solib): Avoid error in referencing memory to
3466 see if any more shared libraries have been added. This is
3467 particularly useful if the target has terminated. Bug reported
3470 Changes from Peter Schauer <pesrem@regent.e-technik.tu-muenchen.de>
3471 in bringing up 3.94.2 on the Sun-3.
3473 * Makefile.dist: Include CFLAGS in rule for cplus-dem.o.
3474 * breakpoint.c (enable_breakpoint): Check for valid watchpoint
3475 expression (in scope) before reenabling watchpoint.
3476 * signame.c (init_sigs): Add missing declaration of i, fix
3477 sys_siglist declaration.
3478 * source.c (list_command): Fixed range computation to use
3480 * stack.c (backtrace_command): Do not allow command if target has
3481 no stack, print informative error message.
3482 * target.c (target_command): Do not write into command line
3483 because this fails if the target command is used in a user defined
3484 command. [This change was enhanced by gnu to support any-
3485 unique-prefix matching on target names.]
3486 * valops.c (value_struct_elt): Avoid infinite loop on an
3487 erroneous attempt to print the member of function (try p main.p).
3489 Mon Apr 1 17:05:45 1991 John Gilmore (gnu at cygint.cygnus.com)
3491 * expread.y (name_no_typename): Avoid reduce/reduce errors
3492 caused by ambiguity in handling NAME_OR_INT and NAME_OR_UINT.
3493 Since the GDB parser really doesn't use name_no_typename in a
3494 name-only context, the parser can't tell the diff between
3495 names and numbers here. Avoid allowing a name_no_typename
3496 to be a NAME_OR_*INT to resolve the conflict.
3498 Sun Mar 31 20:12:07 1991 John Gilmore (gnu at cygint.cygnus.com)
3500 Bugfixes from Mark Fox (markf@wrs.com) (test=testField.c):
3502 * valprint.c (val_print_fields): bitfield printing didn't handle
3503 byte order. Indirect through a few more fns to cope.
3505 * values.c (modify_field): also cope with byte order.
3507 Sat Mar 23 10:02:21 1991 John Gilmore (gnu at cygint.cygnus.com)
3509 Cleanup for release 3.94.2:
3511 * Makefile.dist: Pull REMOTE_OBS. Fix saber includes for BFD
3512 include files. Roll version to 3.94.2.
3514 * coffread.c (init_stringtab): Read length into unsigned char
3515 array before swapping; don't assume 32-bit longs.
3517 * target.c (target_info): Don't bother with get_sym_file, just use
3518 the symfile global variable.
3519 * symtab.h, symfile.c (get_sym_file): Delete it.
3521 * dbxread.c (dbx_symfile_init): Don't depend on long == 4 bytes.
3522 (define_symbol): Set symbol line number to 0 if not gcc-compiled.
3523 (read_type): Replace one more error() with complain().
3525 * mipsread.c (parse_partial_symbols): Replace printf with complain.
3527 * i960-tdep.c: Fix copyright attribution.
3529 * config.gdb: Quote all backquotes in doublequotes. You can
3530 quote me on that. BSD 4.4 shell found this one.
3532 * infptrace.c (throughout): The third argument to ptrace is an
3535 * infrun.c (wait_for_inferior): When program has terminated, we
3536 have to call target_terminal_ours before we pop that target off
3537 the stack (e.g. before a call to target_kill or
3538 target_mourn_inferior). This fixes problem where a program
3539 terminates, then GDB stops for (tty output) and you have to type
3540 "fg" to the shell to resume it. FIXME: This code for what to
3541 do after termination really should be in normal_stop instead.
3543 * gdbcore.h (read_memory_check): Change declaration; it changed
3546 * terminal.h: Include <sgtty.h> before <sys/ioctl.h>, since in BSD
3547 4.4 prereleases, this avoids a bug in their sgtty compatability
3549 * remote.c: Use terminal.h rather than hand-rolling the same.
3551 * signame.c, signame.h (psignal): Arg is unsigned, not int.
3552 * utils.c (strsave, strstr): Fix arg types.
3553 * valprint.c (val_print): lint
3555 MIPS symbol table support from Per Bothner:
3557 * symfile.c (symtab_fns): Remove initializer table that needs to
3558 be hacked for each new symbol file format supported.
3559 (add_symtab_fns): New function, chains symbol table
3560 handlers into the global list.
3561 (symfile_init): Search this list.
3562 * symfile.h: Add next pointer, declare add_symtab_fns.
3563 * coffread.c (_initialize_coffread): Call add_symtab_fns.
3564 * dbxread.c (_initialize_dbxread): Call add_symtab_fns.
3566 * mipsread.c (psymtab_to_symtab_1): return void instead of (struct
3567 symbol *). Thus, we no longer need the hack to trash
3568 pst->filename. Good, since that hack confused code in symfile.c!
3570 (reorder_symtabs, destroy_all_symtabs): Removed static
3571 all_symtabs, which was used to qsort symtabs in reorder_symtabs.
3572 Instead, the latter now uses a temporary array (stack-allocated
3573 from an obstack, and then freed).
3575 (parse_symbol): Added a hack to fix up BLOCK_{START,END} if they
3576 haven't been set in the outermost stBlock of a procedure. This was
3577 a problem with f77 binaries on Ultrix 4.?.
3579 (new_symtab, new_symbol, new_type): Continue changing code to use
3580 obstacks more and otherwise conform to dbxread internal style.
3581 Made the free_code of symtabs be free_linetable (as in dbxread)
3582 instead of free_contents. This implies memory leaks when reading
3583 a new symbol table, until the conversion is finished. Did change
3584 (struct symbol) and (struct type) to be allocated on the
3585 symbol_obstack. Blocks and blockvectors are among the things
3588 * mipsread.c (parse_partial_symbols, parse_fdr): It hasn't been
3589 tested much, but it solved one problem (reported by Meissner), and
3590 cleans up some other things. The problem happened when an
3591 included file contains actual code (functions) and not just
3592 definitions. The mips coff is a little inconvenient there, since
3593 it may cause a procedure to be mapped to the wrong psymtab.
3595 * mips-tdep.c (heuristic_proc_desc): Minor cleanup.
3596 * mips-xdep.c (fetch_core_registers): Minor cleanup. FIXME,
3597 this will need work for the new core paradigm.
3599 Opcode patches from the net:
3601 * mips-opcode.h: fix incorrect disassembly of the mfc1, cfc1, and
3602 ctc1 instructions. Also, the cvt.d.w and cvt.s.w instructions were
3603 missing altogether - they are added here. From Bruce Bauman.
3604 * mips-opcode.h: The low mask for C0 instructions was too small.
3605 From Garrett Lau. I modified the fix to check the entire 32-bit
3608 * ns32k-opcode.h: Fix opcodes for deiw and deid. From Bruce
3611 Thu Mar 21 12:56:46 1991 John Gilmore (gnu at cygint.cygnus.com)
3613 Roll in changes from Per Bothner (Tue, 25 Sep 90 11:11:04):
3615 * dbxread.c (read_type): Pointer subtraction (value_sub in
3616 valarith.c) sometimes failed because the types of the
3617 pointers being subtracted were not identical.
3618 These differed because dbxread.c was allocating pointer types
3619 using dbx_alloc_type+smash_to_pointer_type instead of
3620 lookup_pointer_type. I failed to find a justification for the
3621 former, so I changed it to use the latter. Similarly, I
3622 replaced smash_to_function_type by lookup_function_type,
3623 and smash_to_reference_type by lookup_reference_type.
3625 * mipsread.c (parse_symbol, upgrade_type, parse_procedure,
3626 _initialize_mipsread): corresponding changes.
3628 * symtab.c (smash_to_{pointer,reference,function}_type): eliminate.
3630 * source.c (mod_path): Do tilde_expand on each component of the path,
3631 rather than on the (list of) paths as a whole.
3632 (print_source_lines): Set first_line_listed in addition to
3633 current_source_symtab and current_source_line. If the source was
3634 not findable, after a "dir" command to fix the problem,
3635 a "list" would get the wrong lines.
3637 While I was there... (gnu):
3639 * dbxread.c (read_type): Change error to complaint.
3641 Thu Mar 21 12:56:46 1991 John Gilmore (gnu at cygint.cygnus.com)
3643 First attempt at detailed understanding of symbol table memory alloc.
3645 * dbxread.c (dbx_symfile_read): Free our string table if we
3646 aren't the mainline. Free the "info" struct since we're done with
3648 (init_psymbol_list): Free any previously allocated psymbol lists.
3649 (): FIXME: Should realloc-down the psymbol lists when done reading
3650 the main symbol file?
3652 * symmisc.c (free_symtab): Free fullname field too.
3654 * xm-hp300hpux.h (USG): #undef then #define so Makefile can -D.
3655 (REGISTER_ADDR): Make result type unsigned int.
3657 * xconfig/{i386*,hp300hpux,altosgas,altos}: All config files that
3658 define REGEX must also define REGEX1 (its dependency).
3660 Tue Mar 19 21:28:57 1991 John Gilmore (gnu at cygint.cygnus.com)
3662 * tconfig/i960: No longer works, points you at vxworks960 or
3665 * xgdb.c, XGDB-README: Remove file. Users can get the much
3667 * Makefile.dist: Remove all trace of xgdb.
3669 * breakpoint.c (breakpoint_1): Pass demangle arg to
3670 print_address_symbolic.
3671 (clear_breakpoints): Remove unused function.
3672 (breakpoint_re_set_one): Guts of breakpoint_re_set.
3673 (breakpoint_re_set): Use catch_errors to do them all anyway.
3675 * gdb-int.texinfo (Host versus Target): Add section on what is
3676 a "host" feature versus what is a "target" feature.
3678 * infcmd.c (path_command, path_info): Handle the PATH variable
3679 (object search path) as conveniently as the source search path.
3680 * environ.c (set_in_environ): Set some vars in GDB's environment,
3681 in addition to the child's. PATH, G960BASE, G960BIN for starters.
3682 * source.c (mod_path): New function, from guts of
3683 directory_command, modifies a path. Used by path_command.
3684 (directory_command): Call it.
3685 * defs.h (strsave): Declare.
3687 * utils.c (sevenbit_strings): Add new printing option.
3688 (printchar): Use it.
3689 (strsave): Provide this handy helper routine.
3690 (set_width_command): Rename set_screen_width_command.
3691 (_initialize_utils): "set screen-width" => "set width";
3692 "set screen-height" => "set height"; add sevenbit-strings.
3694 * infcmd.c (do_registers_info): Print floating point registers
3695 in raw hex as well as float format, regardless of whether it is
3696 a "virtual" convertible register.
3697 * tm-sparc.h (PRINT_REGISTER_HOOK): Print every pair of float
3698 regs as a double, just in case it's being used that way.
3699 * values.c (unpack_long): Comment on array/function coercion.
3700 (unpack_double): Argument is in target byte order now. For
3701 integer arguments, just call unpack_long and float the result.
3702 * m68k-tdep.c: include defs.h for "const" handling.
3703 * remote-nindy.c: Use ieee-float stuff.
3704 (nindy_fetch_registers): Unpack double regs to host double, then
3706 (nindy_store_registers): Pack extendeds to host double, flip
3707 around by misusing unpack_double, send as target double.
3709 * tm-vxworks68.h (FRAME_CHAIN): Handle current frame pointer of
3710 zero, as when stopped at the first instruction of a process.
3712 * blockframe.c: Fix filename in comment (param.h => tm.h).
3713 * sparc-tdep.c (skip_prologue): More explicit nudging comments.
3714 * tm-68k.h: Fix typos.
3716 Fri Mar 15 01:09:34 1991 John Gilmore (gnu at cygint.cygnus.com)
3718 Changes from a bringup on the DEC Vax under Ultrix 4.0.
3720 * coredep.c (fetch_core_registers): Pass end-address of register
3721 section to register_addr as expected. Don't call supply_register
3722 if we'd just pass it garbage.
3724 * dbxread.c (read_dbx_symtab): Skip N_NSYMS on Ultrix.
3726 * exec.c (xfer_memory): Use boolean xfer_fn result, not int.
3728 * target.c (push_target, target_info): Cast enums to int for < or
3731 * stack.c (print_frame_info): Identify source file & line
3732 even if we can't print it.
3734 * xm-vax.h (MISSING_VPRINTF): No longer missing in Ultrix V4.0.
3736 Sat Mar 9 10:08:20 1991 John Gilmore (gnu at cygint.cygnus.com)
3738 Clean up IEEE floating point support.
3740 * ieee-float.h: New file.
3741 * ieee-float.c: Write real routines to convert between host
3742 doubles and various target IEEE extendeds.
3743 * m68k-xdep.c: Eliminate assembler code for extended floats.
3744 * xconfig/{3b1,altos,altosgas,hp300bsd,isi,news,news1000,sun2os3,
3745 sun2os4,sun3,sun3os3,sun3os4}: Eliminate use of m68k-xdep.o.
3746 * tm-i960.h, tm-68k.h (REGISTER_CONVERT_TO_VIRTUAL,
3747 REGISTER_CONVERT_TO_RAW): Use ieee_extended_to_double and
3748 double_to_ieee_extended.
3749 * i960-tdep.c: Define ext_format_i960.
3750 * m68k-tdep.c: Define ext_format_68881.
3751 * sparc-tdep.c: Define ext_format_sparc, though unused.
3752 * Makefile.dist (HFILES): Add ieee-float.h.
3753 * inftarg.c: #include "ieee-float.h" for the REGISTER_CONVERT
3756 Obsolete the "coffstrip" program in favor of using BFD's strip.
3758 * nindy-share/coffstrip.c: Remove file.
3759 * nindy-share/nindy.c (coffstrip): Routine to run bfd_strip.
3760 * Makefile.dist: Remove references to nindy-share/coffstrip.c.
3761 * tconfig/nindy960: Remove reference to coffstrip.o.
3763 * Makefile.dist: Roll version number to 3.94.1 (not yet final).
3765 Wed Mar 6 09:56:45 1991 John Gilmore (gnu at cygint.cygnus.com)
3767 * symfile.h: Add symfile_bfd, common between dbxread and coffread.
3768 * dbxread.c: Remove static symfile_bfd.
3769 * infcmd.c (do_registers_info): Add PRINT_REGISTER_HOOK, though
3771 * inftarg.c (child_detach): Pop the child_ops vector if the
3772 detach is successful.
3773 * remote-nindy.c (nindy_create_inferior): Don't push a new
3774 nindy_ops since nindy uses the same one for execution and memory
3776 * core.c (core_ops): Use child_attach and child_create_inferior
3777 rather than default attach and create_inferior functions.
3779 Handle floating point registers in core files.
3781 * sparc-xdep.c (fetch_core_registers): Rewrite for float support.
3782 * sun3-xdep.c (fetch_core_registers): Rewrite for float support.
3783 This version untested since BFD doesn't yet support sun3 core
3785 * hp300hpux-xdep.c: Rewrite fetch_core_registers to new calling
3786 conventions. Fix comments and style. This version has not
3787 been compiled yet, since we have no HP inhouse.
3788 * core.c (get_core_registers): Look for two sections, ".reg"
3789 and ".reg2", and pass both to fetch_core_registers sequentially.
3791 Revise directory path yet again.
3793 * source.c (forget_cached_source_info): Not static any more.
3794 (init_source_path): New default source path is "$cdir:$cwd".
3795 (dir_command): Handle variable arguments ($cdir, $cwd).
3796 (source_info): Print "Compilation directory" rather than
3797 "Originally compiled in" to remind people of $cdir.
3798 (openp): If the path contains $cwd, use current directory.
3799 (open_source_file): If compilation directory is known, replace
3800 first $cdir in path with the compilation directory.
3801 (print_source_lines): Even if we can't print the lines, set the
3802 current symtab and line for future commands like "info source" or
3803 "breakpoint". Also, error message now contains the file name,
3804 line number, and file access error message.
3805 (_initialize_source): Fix help text to describe changes.
3806 * main.c (cd_command): Forget cached source info when we chdir.
3807 * utils.c (strstr): Add simple implementation.
3809 Tue Mar 5 01:41:40 1991 John Gilmore (gnu at fowanton.cygnus.com)
3811 * coffread.c (read_one_sym, init_linetable, init_stringtab):
3812 Byte-swap COFF symbol tables if necessary when reading them in.
3813 Use complain() to replace error message in one spot. Needs
3814 corresponding change in bfd/coff-code.h to make some symbol
3815 swapping routines non-static.
3817 Mon Mar 4 00:53:40 1991 John Gilmore (gnu at cygint.cygnus.com)
3819 Merge changes from Eirik Fuller, for UTek.
3821 * defs.h (errno): Add declaration.
3822 * altos-xdep.c, arm-xdep.c, convex-xdep.c, gould-xdep.c,
3823 hp300hpux-xdep.c, infrun.c, inflow.c, infptrace.c, i386-tdep.c,
3824 i386-xdep.c, pyr-xdep.c, mips-xdep.c, remote-eb.c, remote-nindy.c,
3825 remote-vx.c, source.c, standalone.c, stuff.c, sun386-xdep.c,
3826 symmetry-tdep.c, symmetry-xdep.c, umax-xdep.c, utils.c: Eliminate
3827 declarations of errno.
3829 * remote-eb.c: Define B19200 and B38400 as EXTA and EXTB.
3831 * remote-vx.c: Include <sys/time.h> for UTek; Sun gets it via
3832 <rpc/rpc.h> and <rpc/types.h>.
3834 Sat Mar 2 15:47:55 1991 John Gilmore (gnu at cygint.cygnus.com)
3836 * i960-tdep.c (examine_prologue): Add new argument limit,
3837 which stops the scan at the end of the prologue, or at the PC.
3838 This fixes a problem where it walks down into the code for the
3839 user's statements if that code looks like function prologues.
3840 Mark Fox and I have been bouncing this code back and forth, making
3841 small changes to it. Callers changed to match.
3843 Tue Feb 26 01:47:07 1991 Cygnus John Gilmore (cygnus at yuba)
3845 Cleanup for gdb-3.94 release final:
3847 * Makefile.dist: Remove remote-vx.c, remote-nindy.c, and all
3848 the .c files from vx-share and nindy-share, from the various
3849 macros, since they are not found via ALLDEPFILES.
3850 (SFILES): Add tm-i960.h.
3851 (alldeps.mak rule): Break out ALLDEPFILES_MAINDIR and
3852 ALLDEPFILES_SUBDIR. List all the nindy and vxworks subdir files
3854 (TAGFILES_MAINDIR): Change ALLDEPFILES to ALLDEPFILES_MAINDIR.
3855 (gdb.tar.Z): Use ALLDEPFILES_SUBDIR as well as SFILES_SUBDIR.
3857 Mon Feb 25 16:02:35 1991 Cygnus John Gilmore (cygnus at oldman)
3859 * am29k-tdep.c: Add contribution line.
3860 (examine_prologue): Cache information about function prologues in
3861 the misc-function-vector to avoid lots of references over the
3862 serial line while examining instructions.
3864 * core.c (core_close): New function made from cleanup_core.
3866 * core.c, exec.c, inftarg.c, remote-eb.c, remote-nindy.c,
3867 remote-vx.c, remote.c, target.c, target.h,
3868 Update target_ops vector to add attach, close, and load entries.
3869 Use add_syms_addr_command, not add_file_addr_command, for
3870 add_file. Break out close routine from existing code.
3872 * dbxread.c (really_free_pendings): Don't free pending_blocks;
3873 they are in an obstack.
3874 (read_dbx_symtab): Relocate end_of_text_addr in the psymtab.
3876 (define_symbol): Add symbol type parameter; change callers;
3877 pass type parameter to DBX_PARM_SYMBOL_CLASS macro to allow
3878 it to influence the symbol class on the i960.
3879 (define_symbol): Swap LOC_CONST's into target byte order.
3881 * exec.c (exec_close): New function.
3882 (exec_file_command): Call it.
3884 * findvar.c (read_relative_register_raw_bytes): Doc byte order,
3885 Fix byte order of frame pointer.
3886 (read_var_value): Result of 0 if var's value can't be found,
3887 e.g. missing FRAME_ARGS_ADDRESS. Byte-swap LOC_CONST and
3888 LOC_LABEL values to target order. Add LOC_LOCAL_ARG.
3889 (locate_var_value): Use read_var_value and use its lazy address
3890 as the location of the var's value. Lint.
3892 * i960-pinsn.c (next_insn): Add routine from vxgdb for scanning
3895 * i960-tdep.c (arg_address, i960_frame_find_saved_regs): Remove
3896 obsolete Intel versions in favor of vxgdb versions.
3897 (check_host, byteswap, byteswap_val, reorder_val): Eliminate
3898 code dealing with byte order of values, which Intel did in host byte
3899 order rather than gdb-4's target byte order.
3900 (i960_frame_chain_valid): Move to nindy-tdep.c.
3901 (examine_prologue, skip_prologue, frame_find_saved_regs,
3902 frame_args_address, leafproc_return, saved_pc_after_call,
3903 pop_frame): Add vxgdb versions from Mark Fox.
3904 (examine_prologue, frame_struct_result_address): Add code
3905 to deal with the saved value of G13 (struct return address
3907 (frame_args_address): Modify Mark's version to prefer the
3908 saved value over the current value in the topmost frame.
3909 Cache result in the frame info to avoid performance hair in
3911 (print_fault): Add gdb960 code for printing faults.
3912 (_initialize_i960): Actually call check_host.
3914 * ieee-float.c (ieee_extended_to_double, ieee_double_to_extended):
3915 add stub routines. FIXME, these currently just return zero!
3917 * infcmd.c (program_info): Use PRINT_RANDOM_SIGNAL.
3918 (attach_command): Call target_attach, not target_open, now.
3920 * infrun.c (normal_stop): Make global, not static, for vx_attach.
3921 (child_attach): Rename from child_open.
3922 (wait_for_inferior): Use PRINT_RANDOM_SIGNAL. If stop_pc is zero,
3923 don't confuse it with a zero step_resume_break_address.
3925 * inftarg.c (child_detach): Eliminate inferior_pid test.
3926 (child_files_info): Clean up message a bit.
3927 (child_ops): Use child_attach, not child_open, to attach.
3929 * mem-break.c: #ifdef out the whole file if BREAKPOINT is not
3930 set (e.g. on VxWorks or NINDY). Move read_memory_nobpt from
3931 findvar.c to here, since it depends on the contents of the
3932 shadow_contents of breakpoints, but keep if #if 0 since it is
3935 * nindy-tdep.c: New file, contains nindy_frame_chain_valid, moved
3938 * printcmd.c (address_info): Handle LOC_LOCAL_ARG. Lint.
3939 (ptype_command, display_command): Eliminate have_inferior_p and
3940 have_core_file_p in favor of target_has_stack or
3941 target_has_execution.
3942 (print_frame_args): Handle LOC_LOCAL_ARG. Eliminate duplicate
3943 code for actually finding the values of arguments, though we still
3944 keep track of the maximum stack offset for use in printing unnamed
3945 arguments. Handle missing FRAME_ARGS_ADDRESS.
3947 * remote-nindy.c (i960_print_fault): Move to i960-tdep.c.
3948 (struct nindy_regs): Define registers passed to/from nindy.
3949 (nindy_fetch_registers, nindy_store-registers): Translate between
3950 nindy and GDB formats for the registers.
3951 (dcache_init): Statically allocate the cache, since it was being
3952 allocated by a malloc that was never freed anyway.
3953 (nindy_create_inferior): Error, not core dump, if no exec file.
3954 (nindy_before_main_loop): Use target_load, not target_add_file.
3956 * remote-vx.c (net_load): Specify large timeout for load
3957 requests. Allow user to break out with INTERRUPT.
3958 (net_break): Remove useless code, clean up. Change callers.
3959 (parse-args, skip_white_space, find_white_space): Clean up arg
3960 parsing to cope with quoted strings.
3961 (net_wait, net_quit): Never call error, just return status.
3962 (vx_read_register, vx_write_register): Cleanup status checking.
3963 #ifdef the code based on which CPU we are using (960 or 68k),
3964 FIXME, this should be completely general but it isn't yet.
3965 (vx_xfer_memory, vx_resume): Cleanup status checking.
3966 (vx_run_files_info): Improve message.
3967 (vx_load_command): Renamed from vx_add_file_command. Allow load
3969 (net_ptrace): Remove unused routine.
3970 (vx_wait): Adopt code from vxgdb960 to cope with broken
3971 connections to target machine and prompt to disconnect. Remove
3972 debug printouts. Map some EVENT_'s to SIGnals.
3973 (add_symbol_stub, vx_open): Print names of object files we found,
3974 and "ok" if we read their symbols OK. Clarify output in general.
3975 (vx_attach, vx_detach, vx_kill): Add these commands.
3976 (vx_convert_from_virtual, vx_convert_to_virtual): Simplify.
3977 (vx_run_ops): Turn off all_mem, to avoid spurious msg in the
3978 "info files" output, and create_inferior, since we already have
3981 * stack.c (frame_info): Replace Frame_unknown with 0.
3982 (print_frame_arg_vars): Handle LOC_LOCAL_ARG.
3983 (return_command): Pop until the PC matches as well as the FP,
3984 so it works even if the FP is shared with another function,
3985 as in "frameless" or "leaf" procedures.
3987 * symfile.c (load_command): renamed from add_file_target_command.
3988 (add_syms_addr_command): renamed from add_file_addr_command.
3989 (add_syms_command): Stub to call target_add_syms.
3990 (_initialize_symfile): Change command names and descriptions,
3991 add-file => add-syms, and load from alias to its own command.
3993 * target.c (kill_or_be_killed, maybe_kill_then_attach,
3994 maybe_kill_then_create_inferior): Default for attempts to start
3995 a process, if one is already running, is to ask about killing
3996 it and retry if yes.
3997 (upstack_create_inferior): #if-0 it, strata obsolete it.
3998 (push_target, unpush_target, pop_target): to_close() a target
3999 before unstacking it.
4000 (target_info): Renamed from target_files_info.
4001 (_initialize_targets): Rename "i files" as "i target", accessible
4004 * target.h: Improve comments about the target_ vectored routines.
4006 * tm-i960.h: Remove NINDY-specific stuff to tm-nindy960.h.
4007 Convert commenting style to standard GNU style.
4008 (DBX_PARM_SYMBOL_CLASS): allow LOC_LOCAL_ARG's to be recognized.
4009 (SKIP_PROLOGUE): No longer a no-op.
4010 (SAVED_PC_AFTER_CALL): Now handles leaf procedures.
4011 (*_REGNUM): Sort register numbers.
4012 (REGISTER_BYTES, REGISTER_BYTE, REGISTER_RAW_SIZE,
4013 MAX_REGISTER_RAW_SIZE, REGISTER_CONVERTIBLE,
4014 REGISTER_CONVERT_TO_VIRTUAL, REGISTER_CONVERT_TO_RAW): Float regs
4015 are now 10 byte extendeds, not 8 byte doubles.
4016 (FRAME_CHAIN_VALID): Make this config-dependent, since it differs
4017 for nindy versus vxworks targets. FIXME, this should possibly go
4018 in the target vector.
4019 (EXTRA_FRAME_INFO, INIT_EXTRA_FRAME_INFO): Cache both
4020 frame_saved_regs and arg pointer with each frame.
4021 (FRAMELESS_FUNCTION_INVOCATION): New leafproc support.
4022 (FRAME_ARGS_ADDRESS): Use cached result.
4023 (FRAME_ARGS_ADDRESS_CORRECT): New, avoids g14 guessing.
4024 (FRAME_FIND_SAVED_REGS): Change arg to subsidiary fn.
4025 (PRINT_RAMDON_SIGNAL): Call print_fault.
4026 (POP_FRAME): Now works.
4028 * tm-nindy960.h: Break this off tm-i960.h. NINDY-specific
4029 option parsing and startup; STACK_END_ADDR, FRAME_CHAIN_VALID,
4030 BREAKPOINT, and DECR_PC_AFTER_BREAK are here.
4031 (ADDITIONAL_OPTION_HANDLER): use target_load, not
4034 * tm-vxworks960.h: Break this off tm-i960.h. VxGDB specific
4035 startup; DECR_PC_AFTER_BREAK, and FRAME_CHAIN_VALID are here.
4037 * valarith.c (value_subscripted_rvalue): Avoid handling
4038 floats and doubles specially; it gave alignment errors. Lint.
4040 * valops.c (value_of_variable, value_of_this): Error if unknown
4043 * valprint.c (print_floating): Bcopy rather than pointer-deref,
4044 to avoid alignment problems.
4045 (value_print): Handle unknown value address.
4046 (cplus_val_print): Two args are ignored; remove them. Change caller.
4047 (val_print): Use unpack_long rather than pointer-deref.
4050 (unpack_long, unpack_double): Use bcopy rather than pointer-deref
4051 to avoid alignment problems.
4052 (value_being_returned): Error if return value unknown.
4053 (set_return_value): Add bogosity warning, FIXME. *
4055 * TODO: A woman's work is never done.
4057 * Makefile.dist: Distribute REMOTE_OBS into tconfig files.
4058 Separate INCLUDE_CFLAGS for use with lint. Add LINTFILES.
4059 Add ieee-float.o to OBS.
4060 * tconfig/{nindy960,vxworks68,vxworks960}: Include the desired
4061 REMOTE_OBS remote-interface files in the TDEPFILES and TM_FILE.
4062 * tconfig/i960: FIXME. Half-merge, produce warning if config'd.
4064 Changes to generalize the VxWorks RPC protocol slightly, to handle
4065 i960 as well as 68000.
4067 * vx-share/dbgRpcLib.h (VX_SOURCE_STEP): Add.
4068 * vx-share/reg.h: Produce i960 regs #ifdef I80960
4069 * vx-share/xdr_ptrace.c: Skip FPA registers if 960.
4070 * vx-share/xdr_rdb.h: Add SOURCE_STEP struct and xdr decl.
4071 * vx-share/xdr_rdb.c: Add xdr_SOURCE_STEP routine.
4072 * vx-share/xdr_regs.c: Add xdr_regs, xdr_fp_status, xdr_ext_fp
4073 for i960. Change xdr_vectors to xdr_opaques for 68k registers,
4074 so they will move in target byte order rather than network
4075 byte order (happens to be the same).
4077 Mon Feb 25 03:41:44 1991 John Gilmore (gnu at cygint.cygnus.com)
4079 * tm-convex.h (END_OF_TEXT_DEFAULT): Remove #if 0'd block.
4081 Sun Feb 24 00:55:53 1991 John Gilmore (gnu at cygint.cygnus.com)
4084 Add contribution lines to various files, showing where they
4087 * breakpoint.c (break_insn, check_break_insn_size,
4088 read_memory_nobpt): Remove to mem-break.c.
4090 * xm-*.h, param-no-tm.h, tm-29k.h, valprint.c: Change BYTE_ORDER to
4093 * tm-29k.h (STAB_REG_TO_REGNUM): Warn user if symbol table
4094 entry has bad register number. This change is not
4095 tested in this release, FIXME.
4097 * frame.h: Eliminate Frame_unknown in favor of a simple zero.
4100 * value.h: Force value's contents field to be aligned to hold
4101 at least a double or a long long (if supported). This avoids
4102 doing bcopy's in and out of the contents field.
4104 (step_1): Avoid coredump under obscure circumstances when we
4107 * symtab.h (misc_info): Add field to misc function vector for
4108 any kind of cached information the target code desires. AMD
4109 29000 uses this to avoid repeating examine_function_prologue's.
4111 * coffread.c: Lint. Remove static symfile, read_section_header.
4112 core.c (have_core_file_p): Lint: remove.
4113 expprint.c (print_subexp): Lint.
4114 infptrace.c, valops.c, valprint.c: lint.
4116 Roll in changes from vxgdb-5.0.1:
4118 * symtab.h: Comment byte order of each address class. Add
4119 LOC_LOCAL_ARG for frame-relative args (960).
4120 expread.y: Use LOC_LOCAL_ARG where LOC_ARG is used.
4121 symtab.c, symmisc.c: ditto.
4123 * infrun.c (init_wait_for_inferior): Clear stop_signal.
4125 * remote.c (remote_resume): Error if resume with a signal.
4127 * symfile.c (prim_record_misc_function): Clear misc_info.
4128 (fill_in_vptr_fieldno): Check stub type of arg.
4130 * valops.c (value_cast): Avoid looking up names of types whose
4131 name we don't know, to prevent coredump. Sun CC produces typedef
4132 rtx and the name of *rtx is zero...
4134 Mon Feb 18 21:16:25 1991 John Gilmore (gnu at cygint.cygnus.com)
4136 Roll in changes from final AMD 29000 port (Tiemann).
4138 tconfig/am29k: Add COFF_ENCAPSULATE and TARGET=TARGET_AM29K
4139 for ../include/a.out.encap.h. This might not work now that BFD
4140 is separately compiled. Instead, BFD support for encap will have
4141 to translate machine type 29k into the right COFF_MAGIC.
4143 * infcmd.c: Remove references to inferior_pid that aren't used
4144 in actual ptrace calls; use target_has_execution, etc.
4145 (have_inferior_p): Remove function.
4146 (program_info): Print target info rather than "process number";
4147 avoid gratuitous messages unless from_tty.
4148 (run_stack_dummy, finish_command): Set proceed_to_finish.
4149 infrun.c: Remove inferior_pid refs. Decl & init proceed_to_finish.
4150 main.c: Lint. Lose have_inferior_p().
4151 inferior.h (have_inferior_p): Remove, lint.
4152 (proceed_to_finish): Add flag to ask that all regs be saved
4153 by normal_stop, for the few commands that need it, speeding up
4154 serial I/O. Add comments to stop_registers.
4156 * remote-eb.c: Remove newline from breakpoint message we grep
4157 for. Never time out when running the user program.
4161 Wed Feb 13 15:34:40 1991 John Gilmore (gnu at cygint.cygnus.com)
4163 Roll in changes from vxgdb-5.0.1:
4165 * dbxread.c (read_dbx_symtab): If we encounter a "FORTRAN COMMON"
4166 symbol in its raw form, we are processing an unlinked ".o" file.
4167 See if the target environment has assigned it an address, using
4168 target_lookup_symbol (VxWorks does), and enter it into the symtab
4171 * tm-vxworks.h (FRAME_CHAIN, FRAME_CHAIN_VALID): Override usual
4172 68k versions for a simpler version that assumes zero FP at bottom.
4173 Fixes bug of truncated stack reports.
4175 * target.h (target_lookup_symbol): Define this routine's args
4176 and result, finally.
4178 * target.c (nosymbol): Default routine for target_lookup_symbol.
4179 (target_default): Default lookup_symbol and call_function too.
4180 (files_info): Only print has_all_memory warning if a non-dummy
4183 * remote-vx.c (vx_read_register, vx_convert_to_virtual,
4184 vx_convert_from_virtual): If target does not have floating point,
4185 zero register "values", and avoid doing cross-net conversions.
4186 (vx_lookup_symbol): Rename net_lookup_symbol, add to vectors.
4187 (vx_open): Rearrange code that attaches to target and reads
4188 symbols for all loaded modules, to work if some of the modules
4189 are not accessible. Add symbol_stub() and add_symbol_stub()
4190 as callbacks from catch_errors(). Allow connect attempt to be
4191 interrupted painlessly with ^C (FIXME, there are still some bugs
4192 if the interrupt happens during symbol reading.). Print
4193 final message with puts_filtered, since symbol messages are
4198 * main.c (catch_errors): Only print errstring if non-null.
4199 (command_loop): Avoid an ioctl per command to test ISATTY.
4201 * remote-vx.c (net_load): make static; avoid sophomoric msg.
4202 (vx_xfer_memory): Return correct result!
4203 (vx_files_info): Indicate whether target has float or not.
4204 (vx_lookup_symbol): Complain, not error, if target gone.
4205 (vx_open): Print "Connected" msg before disabling immediate-quit.
4206 [FIXME: lookup_symbol and vx_open changes need testing.]
4208 target.c, remote-eb.c, inftarg.c, am29k-opcode.h, target.h,
4209 tm-29k.h, tmm-vxworks68.h, symfile.c, gdb-int.texinfo: Add
4210 contributor lines and update copyrights to 1991.
4212 Changes from an attempted H-PUX host port:
4214 * infptrace.c (PT_ATTACH, PT_DETACH): Handle HP/UX, which
4215 defines PT_ATTACH and PT_DETACH but not PT_KILL.
4216 * remote-eb.c (eb_open): Misplaced endif kills sysv H/PUX.
4217 * remote-vx.c: include <sys/time.h> for HPUX.
4218 * hp300hpux-xdep.c (fetch_core_registers): Rewrite old
4219 "core_file_command" routine to BFD regime. May not work yet.
4221 Attempted port of "gdb-3.4 Van Jacobson xgdb" to modern gdb.
4223 * xgdb.c: Replace X10 version with some VJ version.
4224 (FIXME: Its copyright assignment is not on record.)
4225 * xgdb.c: Update include files to X11R4 (Xaw crud).
4226 (xgdb_display_source, create_text_widget): fix call to
4227 get_filename_and_charpos. Rewack source window stuff for X11R4
4228 (gleaned from include files, and "nm's" of binary libraries, since
4229 I had no doc available).
4230 (append_selection, append_selection_word): Disable with FIXME
4231 since R4 changed interface here.
4232 (create_buttons): Add back the old set of buttons.
4233 (xgdb_create_window): Fix call to XtInitialize (&argc not argc).
4235 * Makefile.dist (xgdb, xgdb-init.c): Update for X11R4 on Suns.
4236 Roll VERSION to 3.94 (not yet final though).
4238 Sat Feb 9 09:46:25 1991 John Gilmore (gnu at cygint.cygnus.com)
4240 * obstack.h (obstack_ptr_grow, obstack_ptr_grow_fast,
4241 obstack_int_grow, obstack_int_grow_fast): Eliminate
4242 cast on left of assignment, which gives MIPS cc fits and is
4245 * sparc-pinsn.c (print_insn): Eliminate 'set' test, subsumed by
4246 F_ALIAS. Use printf, not fprintf, when not passing a file
4248 (compare_opcodes): Check that identical instructions have
4249 identical opcodes, complain otherwise.
4251 * sparc-opcode.h (st %fsr): Fix opcode "lose" mask. This
4252 was reported by Roland McGrath.
4253 (unimp): Only match if exactly zero instruction. (Roland)
4254 (branches and traps): Generate all variations of these
4255 instructions with macros, based on a single call that defines
4256 each condition name and its binary representation.
4257 (set): Turn on alias bit, to avoid test in sparc-pinsn.c.
4259 * valprint.c (val_print_fields): Take, and use, format parameter.
4260 This means that "p/x struct" again prints the elements in the
4261 desired format. Changed callers.
4263 * stack.c (frame_info): Use filtered output, and indicate wrap
4264 points. Remove kludgy formatting designed to avoid line wrap.
4266 * utils.c (wrap_here): If the line is already full (because
4267 we had printed a long indent or long wrapped string), do an
4268 immediate newline-and-indent.
4270 * m68k-pinsn.c (print_insn_arg): Bugfix from
4271 ntmtv!thompson@ames.arc.nasa.gov (Mike Thompson): 'bkpt #0'
4272 instruction is incorrectly disassembled as bkpt #8.
4274 * dbxread.c (end_psymtab): Bugfix from Peter Schauer
4275 <pesrem@regent.e-technik.tu-muenchen.de>: If you want to set a
4276 breakpoint in a *.y file gdb will say Reading in symbols for *.y...
4277 and then will dump core (sometimes). I traced it back to an
4278 uninitialized symfile_name in psymtab_to_symtab.
4279 (const_vol_complaint): Add quotes to message.
4280 (define_symbol): Only believe line number if gcc_compiled.
4281 Avoid allocating symbol if we will not return it.
4283 Add target strata support so that newly established targets go
4284 into their right place in the target stack (e.g. a new exec file
4285 doesn't wipe out the ability to access the running process).
4287 * target.h, core.c, exec.c, inftarg.c, remote-eb.c,
4288 remote-nindy.c, remote-vx.c, remote.c, target.c: Add to_stratum
4289 and initialize it properly in all the targets.
4291 * target.h: Document strata. Change return type of push_target.
4293 * target.c (nomemory): new function for dummy memory access.
4294 (tcomplain): Rename complain, now also used in symfile.c.
4295 (push_target): Push targets within strata. New return value shows
4296 whether new target is on top of stack or not. Always keep dummy
4298 (target_files_info): Ignore dummy target.
4300 * core.c (core_open): Warn user, and skip accessing file, if the
4301 core target is not the topmost target in the stack.
4302 * remote-nindy.c (nindy_create_inferior): Avoid unpush_target, now
4305 * remote-vx.c: Remove vx_prepare_to_store from vxworks memory
4306 target_ops, it doesn't belong there since we have no regs there.
4307 Change name of target from machine => memory to clarify.
4309 Thu Feb 7 16:32:09 1991 John Gilmore (gnu at spiff.cygnus.com)
4311 * Freeze version 3.93 for release.
4313 * Makefile.dist: Handle vx-share and nindy-share subdirs
4314 properly when building gdb.tar.Z.
4316 * symtab.c: lint; add no_symtab_msg to consolidate the messages
4317 printed in various places, so I could change just one copy.
4319 * dbxread.c, coffread.c: Change references to bfd->iostream
4320 to cast to FILE *, now that BFD avoids needing types defined
4321 in other header files.
4323 Tue Feb 5 21:39:35 1991 John Gilmore (gnu at cygint.cygnus.com)
4325 * command.c, dbxread.c, expprint.c, infcmd.c, infptrace.c,
4326 infrun.c, printcmd.c, remote-nindy.c, source.c, sparc-tdep.c,
4327 sparc-xdep.c, symfile.h, symmisc.c, utils.c, valprint.c: Lint
4328 (actually gcc -Wall).
4330 * dbxread.c: Remove first_global_sym, last_global_sym, since
4331 they are never referenced.
4333 * defs.h (baud_rate): Declare.
4334 main.c: Define it, and add the -b option to set it.
4336 * gdb-int.texinfo: Add text on how to define a new host or target
4337 architecture, prompted by Per Bothner's questions about MIPS
4340 * gdb.texinfo: Document "complaints". Change doc of -q since
4341 gdb no longer prints the copyright and blurb if you specify a file
4342 name to be debugged (just like Emacs). Add doc for Nindy-specific
4343 command line flags for specifying target serial port and such.
4344 Update copyright to 1991.
4346 * gdbcore.h: Remove a large mass of now-useless crud, since BFD
4347 has taken over for us the job of ripping up executable files. The
4348 crud caused Per Bothner's port to not compile.
4350 * infrun.c (normal_stop): Avoid printing "Program exited
4351 normally" if we are in batch mode. This allows a GDB which
4352 executes a program on a target system, to behave like a Unix
4353 command (input from stdin, output to stdout, no extraneous
4356 * main.c (main): Allow additional machine-dependent command line
4357 options to be specified with the ADDITIONAL_OPTIONS,
4358 ADDITIONAL_OPTION_CASES, ADDITIONAL_OPTION_HELP, and
4359 ADDITIONAL_OPTION_HANDLER macros. Also allow machine-dependent
4360 processing to occur just before the main loop with
4361 BEFORE_MAIN_LOOP_HOOK.
4362 (main): If a "core file" argument is specified, and it is not a
4363 core file, try it as a process ID to attach.
4364 (symbol_completion_function): Attempt to cope with
4365 "show screen-" TAB, not very successfully. This needs more work,
4367 (batch_file): New function, returns whether we are reading
4368 commands from an interactive tty on stdin, or from somewhere else.
4369 Called by normal_stop since it doesn't get from_tty passed down
4370 to it like many commands do.
4372 * remote-nindy.c: Handle command line options for nindy
4374 (nindy_before_main_loop): Prompt user for tty name if they
4375 don't specify it before getting to the interactive command loop.
4377 * tm-i960.c: Add ADDITIONAL_OPTIONS, etc, to handle -O, -brk,
4378 and -r command line options. Also add hook before main loop
4379 to make it easy to specify a tty.
4381 * TODO: More things to do, one done.
4383 Mon Feb 4 23:57:39 1991 John Gilmore and Mike Tiemann (at cygint.cygnus.com)
4385 * dbxread.c: Make complaint() calls pass pointer, not struct.
4386 Add complaints about badly formatted C++ type information
4387 (const/volatile indicator, and parse errors resulting in
4388 error_type). Fix C++ virtual member fn comment.
4389 (read_struct_type): Avoid bumping pointer if we got a parse
4390 error; this prevents our walking beyond the end of a string.
4391 Terminate loop on null char as well as semicolon.
4392 (process_one_symbol): Fix the LBRAC fix so that it uses the
4393 last previous SLINE, FUN, or SO record's PC address. C++ debug
4394 symbols did not have SLINE records in a useful order compared
4395 to the LBRAC records.
4396 (define_symbol): Handle "catch" records.
4398 * symtab.c (check_stub_type): Added new complain
4399 `stub_noname_complain' and added a consistency check to
4400 keep the debugger from crashing when finishing from an
4401 exception frame. A real fix will be needed later.
4403 Sat Feb 2 10:43:05 1991 John Gilmore (gnu at cygint.cygnus.com)
4405 * infcmd.c (attach_command): Make global.
4407 * Makefile.dist (REMOTE_OBS): Make these compile by default,
4408 but make them easy to comment out. Perhaps later they should
4409 be enabled by what CPU you configure for? FIXME.
4410 (VERSION): Roll to 3.93.
4411 (pinsn.o): Remove rule for obsolete file.
4412 (dbxread.o,coffread.o,mipsread.o): Use ${srcdir} explicitly.
4414 Run down a problem that manifested by printing the wrong function
4415 name in stack traces of read_ofile_symtab. Turned out that the
4416 problem was the SunOS 4.1.1 (and previous) C compiler outputs
4417 the LBRAC symbol with an address in the *data* segment, which
4418 blew our binary search through the blocks.
4420 * dbxread.c: Use the complain() facility consistently to bitch
4421 about problems in the symbol file we are reading.
4422 (finish_block): Add code to check the nesting of the blocks;
4423 complain and Procrust them to fit if wrong.
4424 (make_blockvector): Check the order of the blocks, complain
4425 [but don't cope] if wrong.
4426 (process_one_symbol): ifndef SUN_FIXED_LBRAC_BUG, check LBRAC
4427 symbols to be sure their PC value is greater than the last SLINE
4428 (line number) symbol we've seen, complaining and adopting the
4429 SLINE PC value if wrong.
4431 * symfile.h (struct complaint, complaint_root, complain,
4432 clear_complaints): Add.
4433 * symfile.c (complain, complaint_root, clear_complaints): Add
4434 facility to deal with non-fatal complaints and to regularize their
4436 (symbol_file_add): Clear complaint counters to allow new complaints.
4437 (initialize_symfile): Add 'set complaints' and 'show complaints'.
4439 * dbxread.c (dbx_symfile_read): Remember the address and size
4440 of the string table for the main symbol file, so we won't read it
4442 (dbx_psymtab_to_symtab): Fix the check for main symbol file,
4443 to avoid reading the string table yet again. Lint.
4444 (throughout): Improve filtered output, including word wrap.
4445 (read_range_type): Improve Bothner's fix to handle other types too.
4447 * utils.c: Improve line wrap implementation. Handle unlimited
4448 width by making chars_per_line unsigned.
4449 (puts_filtered): New, easy, function.
4451 * defs.h (puts_filtered): add.
4453 * mipsread.c (compare_symbols, sort_symtab): Remove these fns,
4454 call the identical sort_symtab_syms() in symfile.c instead.
4456 * expread.y: Suggest the `file' command rather than `symbol-file'.
4458 * command.h (enum var_types): Add zinteger for seroable
4460 * command.c (do_setshow_command): Handle var_zinteger. Restructure
4461 nested if's into a switch.
4463 * breakpoint.c (bpstat_print): If bpstat "print" flag is not set,
4464 we did not stop because of a breakpoint (it must have been for
4465 some other reason, like a "stepi"), so don't print anything.
4467 * symtab.c: Include <sys/types.h> all the time. Now that BFD
4468 doesn't include <sys/types.h>, old SunOS's require it for
4471 Sat Feb 2 10:39:15 1991 Per Bothner (bothner@cs.wisc.edu)
4473 A test port of gdb-3.92.6 to the Sony NEWS.
4476 Don't normally link in remote- or vx stuff.
4477 Some of it doesn't compile, and it wastes space for 99% of the users.
4478 Remove reference to no-longer-used HAVE_VPRINTF.
4479 Fixed BFD_DEP typo to BFD_DIR.
4481 Fix cast in arg to bfd_h_getlong.
4482 Make char *prefix be const.
4483 Fix how certain range types are mapped into builtin unsigned int types.
4485 Remove 2 #includes. They cause errors (on Sony, at least),
4486 and aren't needed (they wern't in earlier versions).
4488 print_address_symbolic should never demangle labels
4489 (since it prints *assembler-level* labels).
4491 [This was superseded by the change to printcmd below.]
4494 Add some "volatile" return types to avoid warnings.
4495 If MISSING_VPRINTF add vprintf function and not just macro
4496 (since vprintf is used in printcmd.c).
4498 Unless __GNUC__, use obstack_grow instead of obstack_ptr_grow.
4499 (The latter isn't grokked by some PCC-based compilers.)
4501 [This change is in abeyance, we prefer to fix obstack_ptr_grow.]
4503 Make chunk size of dont_print_obstack 32*4 instead of default 4096.
4504 * nindy-share/coffstrip.c
4505 Added some forward declarations (otherwise, gcc complains
4506 about implicit extern redefined as static).
4508 Sun Jan 20 02:38:19 1991 John Gilmore (gnu at cygint.cygnus.com)
4510 Changes inspired by Per Bothner:
4511 * printcmd.c (print_address_symbolic): Take additional parameter
4512 specifying whether to demangle.
4513 (print_address): Pass in asm_demangle to control demangling.
4514 (print_address_demangle): New fn, takes explicit arg to control
4516 * utils.c: Add new vars demangle and asm_demangle, and let them
4518 (fputs_demangled): If !demangle, just print the argument.
4519 (fprint_symbol): If !demangle, just print raw symbol.
4520 * valprint.c (val_print): Call print_address_demangle rather than
4521 print_address, to cause demangling to depend on the global
4522 rather than assembler-level demangling setting.
4523 * WHATS.NEW, gdb.texinfo: Document.
4525 * main.c (show_command): Show all settings if no arg.
4526 (initialize_main): Make "info set" the same as naked "show".
4527 * command.c (cmd_show_list): Handle prefix commands in the
4528 list, and print the name of the setting as well as its English
4529 description and value.
4531 Allow gdb functions to specify where a line should wrap if it
4532 exceeds the size of a terminal line. Use it to make the output
4534 * utils.c (set_screen_width_command): New fn, mallocs a buffer
4535 of the right size when screen width changes.
4536 (set_screensize_command, screensize_info): Remove #if 0'd fns.
4537 (wrap_here): New fn, indicates a point in the output where we
4538 should wrap the line rather than just letting it overflow at a
4540 (fputs_filtered): Implement wrapping.
4541 (n_spaces): New fn, returns a pointer to N spaces.
4542 (print_spaces_filtered): Use n_spaces.
4543 * defs.h (n_spaces): Declare.
4544 * stack.c (print_frame_info): Wrap with 4-space indent after
4545 fn name and before filename and line number.
4546 * printcmd.c (print_frame_args): Wrap with 4-space indent
4547 before each argument name is printed.
4548 * valprint.c (value_print): Wrap with no indentation before
4550 (val_print_fields): Wrap with indentation relative to nesting
4551 level before each field name.
4552 (val_print): Wrap with nesting indentation before array elements.
4553 * command.c (do_setshow_command): Avoid extra newlines,
4554 wrap with 4-space indent around values printed, end with period.
4555 * WHATS.NEW, gdb.texinfo, gdb-int.texinfo: Document.
4557 * breakpoint.c (breakpoint_1): Implement addressprint for
4558 "info breakpoints" display. Change file name and line number
4559 format to " at file:nnn" rather than " (file line nnn)".
4560 * gdb.texinfo: Document.
4563 Fri Jan 18 07:21:25 1991 John Gilmore (gnu at cygint.cygnus.com)
4565 Frozen for gdb-3.92.6 release.
4567 README, WHATS.NEW: Update for 3.92.6 release.
4569 tconfig/{altos, i386v, i386v32, m88k, umax}: Eliminate
4570 coffread.o from configs since it is now built by default.
4571 tconfig/{3b1, altosgas, arm, convex, hp300bsd, hp300hpux,
4572 i386v-g, i386v32-g, isi, merlin, news, news1000, np1, pn,
4573 pyramid, symmetry, vax, vxworks68}: Eliminate dbxread.o
4574 from configs since it is now built by default.
4576 Makefile.dist: Update for release 3.92.6. Handle files that
4577 have been moved to ../include, ../getopt, or ../bfd. Add
4578 saber.suppress and tests directory. Add config.status to
4579 the release (it will say "none").
4581 coredep.c: Minor formatting fixes.
4583 These changes were made in early December but only checked in now:
4584 * nindy-share/Onindy.c, nindy-share/coffstrip.c,
4585 nindy-share/nindy.c: lint
4586 * nindy-share/nindy.c (ninStopWhy): Don't byteswap the
4587 register values coming back from the target; we store values
4588 in target byte order everywhere.
4590 Wed Jan 16 19:01:37 1991 John Gilmore (gnu at cygint.cygnus.com)
4592 * am29k-opcode.h, am29k-pinsn.c: Add 29050 opcodes.
4594 * valprint.c (cplus_val_print, val_print_fields): New functions,
4595 which print C++ objects. They conspire to avoid printing a
4596 virtual base class more than once, following all the twists and
4597 turns of C++ virtual base rules.
4598 (val_print): Call the above rather than do it by hand.
4600 * symfile.c (symbol_file_add): Only reset symfile_mtime for main
4601 symbol file, not for added files like shared libs. This really
4602 needs to be generalized to a timestamp per file.
4604 * core.c (cleanup_core): Avoid coredump if no core file.
4606 * config.gdb: Accept -host or -target in place of +host or
4609 * coffread.c (find_linenos): Avoid desupported BFD interface
4610 to line numbers. We still read them manually rather than using
4611 BFD's "generic" features.
4613 * gdbrc.tex, threecol.tex: Add GDB reference card and its
4615 Makefile.dist: Add refcard to OTHERS list for creating tar files.
4617 * Makefile.dist: Eliminate use of $< in explicit targets.
4619 * readline/Makefile: Use $< rather than $*.c, which does not
4620 include the VPATH in GNU Make.
4622 * tconfig/i960-bout, tconfig/i960-coff: These are identical
4623 copies of tconfig/i960, added for global configuration
4624 compatability. All i960 versions can read both coff and b.out.
4626 * tm-88k.h: Fix multiline macro that lacked \'s. Remove
4627 COFF_FORMAT and COFF_CHECK_X_ZEROES since these are now handled
4630 * TODO: Think of more things to do.
4632 Wed Jan 2 19:09:29 1991 John Gilmore (gnu at spiff.cygnus.com)
4634 tconfig/{am29k,i960,sun2*,sun3*,sun4*}: Eliminate config
4635 of sdb versus dbx debug symbols. Add kludge for 68881 80-bit to
4636 64-bit float conversion.
4638 tconfig/sun4, tconfig/sun3, xconfig/sun4, xconfig/sun3: Make
4639 equivalent to sun?os4 so global config works.
4641 Wed Jan 2 18:20:51 1991 John Gilmore (gnu at spiff.cygnus.com)
4643 Fix from Eberhard Mattes <mattes@azu.informatik.uni-stuttgart.de>
4645 * main.c: Only declare linesize once; declare pagesize not at
4646 all, since it is never used.
4647 (main): Clear newly allocated line before it is used.
4649 Fri Dec 28 00:13:42 1990 John Gilmore (gnu at cygint)
4651 Further stabilization for the Intel 960.
4653 * Makefile.dist: Parameterize the location of the "include"
4654 and "bfd" directories, as well as "getopt". Add symfile.c.
4655 Link in both dbxread and coffread. Fix up "make depend" to
4656 rewack the locations of include, bfd, and getopt in its output.
4658 * README: Document moving include files, improve some of
4661 * coffread.c: Move common code out to symfile.c. Change
4662 symbol_file_command style interface to use new *_symfile_init
4663 and *_symfile_read interface under BFD. Use BFD internal
4664 info to locate line table, symbols, etc.
4666 * core.c (core_fetch_registers): Rename to get_core_registers
4667 to avoid confusion with fetch_core_registers.
4668 (register_addr): Move to coredep.c, which is already machine
4669 dependent. This leaves core.c pretty clean of dependencies.
4671 * coredep.c (register_addr): Accept this routine from core.c.
4673 * dbxread.c: Move common code (with coffread.c, etc) into new
4674 symfile.c. Each psymtab now contains a pointer to the
4675 format-dependent function that knows how to read it in. Make
4677 (dbx_psymtab_to_symtab): Renamed from psymtab_to_symtab_2.
4678 (process_one_symbol): Add code to complain about a "compiler bug
4679 we muzzle here", if we actually see it.
4681 * eval.c (evaluate_subexp): Insert missing "break" statements
4682 in code that determines whether a variable is an lvalue in
4683 memory, register, or whatever. I detected this via a compiler
4684 bug in which it *almost* mashed out the whole switch statement.
4686 * gdb-int.texinfo: Add minor sections on configuring gdb for
4687 release, and about the README file.
4689 * infcmd.c (registers_info): Fix formatting somewhat. Still
4690 not as pretty as before, but it handles byte swapping.
4692 * remote-nindy.c: If data cache routines are interrupted while
4693 waiting for the remote end, be sure that any uninitialized cache
4694 blocks are on the free list, not on the valid list!
4696 * symfile.h: Flesh out this header file with all the various
4697 routines and variables that have been merged in from dbxread.c
4698 coffread.c, and symtab.c to symfile.c.
4700 * symfile.c: New file, containing code common to dbxread.c,
4701 coffread.c, and some code from symtab.c. All generic code for
4702 reading symbol files should be in here now.
4703 (unrecord_misc_function): Remove unused function.
4705 * symtab.h: Remove file-reading things to symfile.h.
4707 * symtab.c: Remove file-reading things to symfile.c.
4709 * tm-i960.h: Fix FRAME_CHAIN types; define PRINT_RANDOM_SIGNAL
4710 to decode i960 fault types.
4712 * target.h, remote.c, remote-eb.c, remote-vx.c, remote-nindy.c,
4713 target.c: Change type of the "resume" function from int to void,
4714 since its result was never used.
4716 Sat Dec 22 02:51:40 1990 John Gilmore (gnu at cygint)
4718 * main.c: Replace "stupid" with "caution"; you now "set caution
4721 * printcmd.c (print_scalar_formatted): Fix typo in 'g' format
4723 * infcmd.c (do_registers_info): Call val_print to deal with the
4724 byte order of the registers being printed. FIXME, this makes
4725 the formatting of the output uglier.
4727 * infcmd.c (wait_for_inferior): If PRINT_RANDOM_SIGNAL is
4728 defined, call it for signals the debugger doesn't itself use.
4729 The i960 uses this for more detailed fault information.
4731 * remote.c (remote_open): If arg is null, print help rather than
4734 * sparc-xdep.c (register_valid): Avoid declaring size, since
4735 various modules will think of various sizes depending on the
4736 architecture of their tm-file. FIXME, we need protection against
4737 actually entering one of those modules, which would clobber
4738 storage if not for the target architecture compiled into gdb.
4740 * stack.c (up_command, down_command): Always print the frame
4742 (up_silently_command, down_silently_command): New commands
4745 * i960-pinsn.c (reg), i960-tdep.c: Lint.
4747 * i960-tdep.c (i960_frame_chain_valid): Lookup_symbol now takes
4748 more parameters than it used to.
4750 * findvar.c (registers): Increase slop to 256 bytes, which should
4751 protect us against even most RISC machines with large register
4753 (locate_var_value): Move declaration inside related ifdef.
4755 * remote-nindy.c (): Use TIOCSETN rather than TIOCSETP
4756 throughout, to avoid throwing away buffered input from the board.
4757 (nindy_wait): Supply_register takes addr_of_value, not value.
4758 (i960_print_fault): Renamed from i80960_fault.
4759 (nindy_fetch_registers): Avoid have_regs stuff, just get them.
4760 (nindy_store_registers): Avoid regs_changed stuff, just stuff
4762 (nindy_create_inferior): Don't bother to write PC_REGNUM since
4763 we can set the PC in the call to proceed(). Unpush nindy_ops
4764 before pushing it on top, to avoid message to user. Eliminate
4765 commentary from Unix machines that just misleads here.
4766 (reset_command): Fix error message to suggest target command.
4768 Wed Dec 19 11:03:56 1990 John Gilmore (gnu at cygint)
4770 Release 3.92.5 as frozen.
4772 Stabilize the merged release...with help from lint, Saber C,
4775 Everywhere: Add include files needed to declare return types
4776 of functions called.
4778 * gdb.texinfo: Roland Pesch is documenting gdb, glory be!
4780 * breakpoint.h: Add undeclared breakpoint functions, and some
4781 functions for display handling since I couldn't think of a better
4784 * breakpoint.c (insert_breakpoints): Make code for disabling
4785 shared library bkpts more likely to work. It's used when we
4786 rerun a program and stop before the shared library has been
4788 (breakpoint_cond_eval, bpstat_stop_status): Pass arg as int,
4789 cast from pointer, so it squeezes through catch_errors.
4790 (bpstat_stop_status): Fix logic broken some time ago. We now
4791 always create a bpstat if the stop address matches a breakpoint,
4792 even if we don't stop there -- just like the old code used to do
4793 before I got my fingers into it (sigh).
4794 (breakpoint_1): Print "ignore count" after "stop only if"
4795 condition, since that's how it actually works.
4796 (mention): Handle watchpoints as well as breakpoints.
4797 (watch_command): use set_raw_breakpoint and mention to do most
4798 of the work (and initialize all the fields!). Only pass one
4799 arg to parse_c_expression, since that's all it takes.
4801 * command.c (not_just_help_class_command): Rename arg to args
4802 since we ignore "unused argument" warnings on vars named "args".
4803 inflow.c (child_terminal_info): ditto.
4804 infptrace.c (kill_inferior): ditto
4805 main.c (catch_errors, version_info, quit_command, pwd_command,
4806 source_command, dump_me_command, editing_info,
4807 set_history_size_command, set_history, show_history,
4809 stack.c (locals_info): ditto
4810 target.c (target_files_info): ditto
4811 valprint.c (set_input_radix, set_output_radix): ditto
4813 * core.c: Remove old variables for handling core and exec file
4814 sections (data_start, data_end, stack_start, stack_end,
4815 reg_stack_start, reg_stack_end, reg_stack_offset, text_start,
4816 text_end, exec_data_start, exec_data_end, text_offset,
4817 exec_data_offset, data_offset, stack_offset). They're
4818 superseded the more general build_section_table and
4820 (get_exec_file): Mention the `file' command.
4821 (read_memory_check): Rename to memory_error, and only call it
4822 in the case of an actual error.
4823 (read_memory, write_memory): call memory_error.
4824 (core_fetch_registers): Register section name is ".reg".
4826 coredep.c: Remove a bunch of crud now that all this file does
4827 is pull the registers out of a core file.
4828 (fetch_core_registers): Rewrite to actually work, I hope.
4830 dbxread.c: Use a.out.gnu.h, not system a.out, now.
4831 Replace index() with strchr(). Remove all the pre-BFD macro
4832 definitions for accessing the symbol file.
4833 (struct dbx_symfile_info): Encapsulate the information that
4834 dbx_symfile_init needs to pass to dbx_symfile_read in this
4837 (dbx_new_init, dbx_symfile_init, dbx_symfile_read,
4838 dbx_symfile_discard): Rearrange symbol file reading to divide
4839 the format-specific part from the format-independent part,
4840 leaving the format-independent part such as file name expansion
4841 and opening in symtab.c. This replaces
4842 partial_symbol_file_open and partial_symbol_file_read.
4843 Symbol_file_read, add_file, add_file_target_command,
4844 add_file_addr_command move to symtab.c. Pass an explicit
4845 "mainline" flag for when reading the main symbol table, rather
4846 than relying on the offset address to be zero or nonzero.
4848 (dbx_symfile_read): Don't allow void *'s to be printed as
4850 (SWAP_SYMBOL): Use bfd routines to byte-swap the symbols.
4851 (ADD_PSYMBOL_TO_LIST): Make the "function call rather than
4852 macro" debug version really work.
4853 (read_dbx_symtab): Remove unref'd parameter inclink.
4854 Avoid swapping N_SLINE symbols, for speed.
4855 Merge N_TEXT!N_EXT case with the other external symbol
4856 definitions' case. Add comments.
4857 (start_psymtab): Allocate the symfile name in the psymtab on
4858 the psymbol_obstack, rather than using the caller's storage.
4859 (end_psymtab): Only allocate a dependencies list if there are
4861 (psymtab_to_symtab_2): Use BFD when reopening file to read
4862 its symbols for real.
4863 (read_struct_type): Add FIXME comments where it needs work
4865 (read_huge_number): Add FIXME about overflows.
4866 (read_range_type): Add FIXME about comparing a long to 1<<32.
4868 * coffread.c: Minor changes to move things closer to the new
4869 regime with symtab.c and dbxread.c Major work is still needed
4872 * exec.c (exec_file_command): Remove old variables (see core.c
4874 (xfer_memory): If memory transfer is right at the end of a
4875 section, don't lose.
4877 * findvar.c (get_saved_register): If value is in a real
4878 register, LVAL is lval_register, not lval_memory.
4880 frame.h: Declare print_sel_frame and record_selected_frame.
4882 gdb-int.texinfo: New file, for GDB internals documentation.
4883 Very simple, unformatted doc of cleanups is there for now.
4885 gdbcore.h: Remove obsolete variables that described a.out
4886 section addresses and offsets. (See core.c above.)
4887 Declare fetch_core_registers and registers_fetched.
4889 getopt.c: Declare char *alloca(); even on SPARC.
4891 infcmd.c (run_command): Call target_kill rather than
4893 (step_command, next_command, stepi_command, nexti_command):
4894 Declare from_tty parameter even though we don't use it.
4895 (run_stack_dummy): argument BUFFER is a char array, not
4896 a pointer to REGISTER_TYPE.
4897 (finish_command): using_struct_return needed a value *,
4898 not a struct symbol *.
4900 * infptrace.c (child_xfer_memory): To avoid dependency on
4901 where sections are in memory, try PT_WRITE_D and if that fails,
4902 try PT_WRITE_I. Most Unixes don't care which you use.
4904 * infrun.c (step_resume_break_shadow): Change to array to
4905 match other breakpoint shadow storage.
4906 (clear_proceed_status): Pass address of bpstat to
4907 bpstat_clear, not the bpstat itself.
4908 (child_create_inferior): FIXME comment about if the child
4910 (start_inferior): Remove old function.
4911 (child_open): Use target_kill rather than kill_inferior.
4912 (wait_for_inferior): Ditto.
4913 (insert_step_breakpoint, remote_step_breakpoint): Use
4914 new step_resume_break_shadow.
4916 * inftarg.c (child_wait): If all child processes die,
4917 pretend that the one being waited for exited with signal 42.
4919 * main.c (command_line_input): When scanning for comments,
4920 don't coredump on unclosed quotes.
4921 (quit_command): Use target_kill rther than kill_inferior.
4922 (_initialize_main): Rename class_user from "user" to
4925 * printcmd.c (print_command_1): Initialize "fmt" if no format
4926 is specified by the user.
4927 (print_frame_args): Only add to args_printed if we are
4928 actually fetching args from the stack (avoiding undefined
4930 (_initialize_printcmd): Remove bogus \{ from string.
4932 * remote-eb.c (eb_open): Avoid coredump on no argument.
4934 * remote-nindy.c: Bring out of Intel environment into new
4935 target environment. Remove all conditional compilation on
4936 I80960. Massive hacking throughout.
4937 (nindy_xfer_inferior_memory): New routine stolen from
4939 (nindy_create_inferior): New routine pieced together, probably
4940 not quite working yet.
4941 (nindy_ops): New target_ops struct for nindy.
4943 * remote-vx.c: Use write_memory rather than target_write_memory
4944 to get error checking.
4945 (vx_add_file_command, vx_open): Use symbol_file_add rather than
4947 (vx_create_inferior): Use target_terminal_ours...
4949 * signame.c (_initialize_signame): Always initialize, since
4950 we need the table for things other than psignal.
4952 * solib.c (solib_add): Use symbol_file_add, not add_file.
4953 (solib_address): Return boolean result rather than struct
4954 pointer which nobody else knows the type of.
4956 * sparc-tdep.c, valops.c: Use write_memory rather than
4957 target_write_memory, to get error checking.
4959 * stack.c (locals_info, catch_info, args_info,
4960 get_selected_block, frame_command, up_command): Use
4961 target_has_stack, rather than have_inferior_p or
4964 * sun3-xdep.c (fetch_core_registers): Rewrite for new BFD regime.
4966 * symfile.h: New file, defining the interface between the
4967 generic and object-file-specific symbol reading code.
4969 * symtab.c: Move generic symbol-reading interface to symtab.c,
4970 from dbxread.c, coffread.c, mipsread.c, etc. Add symtab_fns
4971 table to map BFD targets to symbol-reading modules in GDB.
4972 Change index to strchr.
4973 (lookup_struct_elt_type): Use error() rather than hand-made
4974 simulations thereof.
4975 (lookup_partial_symbol): Speedup slightly when length == 0.
4976 (symbol_file_add): New function.
4977 (symbol_file_command): Call it.
4978 (symfile_open, symfile_init): New function.
4979 (add_file_target_command, add_file_addr_command): moved from
4982 * target.c (target_command): use target_kill.
4984 * target.h (target_files_info): Don't declare, never called
4987 * tm-sun2.h, tm-sun3.h (STACK_END_ADDR): Use system include
4988 files to determine stack end address.
4990 * valarith.c (value_x_binop, value_x_unop): Change error message
4991 to be more useful. Pass proper argument to value_struct_elt.
4993 * valops.c (value_assign): FIXME comment that long long
4994 bitfields will break here.
4996 * Makefile.dist: Add symfile.h, remote-nindy.c, remote-eb.c.
4997 Update `make saber_gdb' to work better.
4999 * TODO: A woman's work is never done.
5001 * cplus-dem.c, environ.c, inferior.h, infrun.c, inftarg.c,
5002 main.c, obstack.c, printcmd.c, remote-eb.c, remote-nindy.c,
5003 remote-vx.c, remote.c, solib.c, source.c, sparc-pinsn.c,
5004 sparc-tdep.c, sparc-xdep.c, symmisc.c, symtab.c, symtab.h
5005 target.c, terminal.h, tm-sparc.h, tm-sunos.h, utils.c,
5006 valops.c, valprint.c, exec.c: Lint.
5009 Wed Dec 12 23:44:15 1990 John Gilmore (gnu at cygnus.com)
5011 Continuing Intel 960 port merge of GDB.
5013 * Makefile.dist: Merge i960 "nindy-share" files. Rename
5014 malloc.h to gmalloc.h to avoid name conflicts in /usr/include.
5015 Don't ship gdb.dvi in tar file. Link gdb with init.o, not init.c.
5016 Wack over "make depend" so it handles files in subdirectories
5017 vx-share, nindy-share, bfd, and in the current directory.
5019 * blockframe.c (get_prev_frame_info): Remove fatal error
5020 if stack not defined.
5022 * core.c (core_open, core_detach): New functions that handle
5023 the old "core-file" command as "target core" and "detach" instead.
5024 (core_file_command): Call them.
5025 (core_xfer_memory): Use common routine xfer_memory.
5027 * dbxread.c: Include a.out.gnu.h, not system a.out.h.
5028 dbxread now uses bfd for everything but symbol reading itself.
5029 BFD internals are used to drag out the relevant file offsets.
5030 (partial_symbol_file_open): Change args all around for BFD.
5032 * symtab.c: Rename "value" to "val" everywhere, so we can
5034 (symbol_file_command): New command, moved from dbxread.c
5035 and coffread.c. It uses BFD to read the file, then vectors
5036 based on its type, to dbx or coff symbol readers.
5037 * symtab.h: Extern a few vars for symbol_file_command.
5039 * target.h: Breakpoint takes a char * save area, not a char **.
5041 * valprint.c (val_print): When unpacking bitfields, offset
5042 the address in gdb of the value, if it is declared with a shorter
5043 type. Remove the last "runtime kludge test" of host byte order.
5045 * utils.c: Remove old my_bfd_read routine.
5047 * stack.c (frame_info): Use target_has_stack. Print program counter
5048 register's actual name rather than "pc", since it's called the
5049 "ip" (instruction pointer) on the i960 (sigh).
5051 * target.c (target_command): Add command for selecting a target
5052 type and calling its open routine. This is used for initiating
5053 communication with a particular target, in a generic way.
5055 * tm-i960.h: Update for modern gdb. Remove semicolons from
5056 various macros. Handle reading struct return convention, and
5057 error-out attempts to return structs with the "return" command.
5058 Be sure gdb doesn't think we know how to call functions in the
5061 * i960-tdep.c: Rename FRAME_CHAIN_VALID and FRAME_FIND_SAVED_REGS
5062 to i960_xxx in lower case.
5063 (arg_address): Circumvent errors due to LOC_ARG_BLOCK
5064 not being defined yet.
5066 * remote.c (remote_open): Call start_remote to initialize
5067 wait_for_inferior during open.
5068 (remote_xfer_inferior_memory): Return length written rather
5071 * remote-vx.c (target_command -> vx_open): Use new generic
5073 * remote-eb.c, inftarg.c, exec.c: ditto.
5075 * infrun.c: Fix comments.
5076 (attach_program -> child_open): Use new generic target command.
5077 (wait_for_inferior): Clear saved register values before target_wait,
5078 so target_wait can set some of them if convenient.
5080 * infptrace.c (fetch_inferior_registers, store_inferior_registers):
5081 Return success indicator, not void.
5082 (child_xfer_memory): Avoid fetching initial word if we'll
5083 overwrite it anyway.
5085 * infcmd.c (attach_command): Use new generic target open routine.
5086 (_initialize_infcmd): Update doc on attach and detach commands.
5087 (do_registers_info): Merge in a byte-order problem as a FIXME
5090 * findvar.c (find_saved_register): Avoid problem in current frame.
5091 (read_relative_register): Ditto.
5092 (write_register): Convert byte order on the way out.
5094 * exec.c (file_command): Add.
5095 (add_to_section_table, exec_command): Use new bfd_map_over_sections.
5096 (xfer_memory): Common function between core_xfer_memory and
5098 (exec_xfer_memory): Use it.
5100 * pn-opcode.h: Document that a "PN" is a Gould PowerNode.
5102 * breakpoint.c, breakpoint.h, symtab.h, value.h, frame.h, utils.c,
5103 valops.c, stack.c, target.c, sparc-xdep.c, source.c, printcmd.c,
5104 infcmd.c, i960-pinsn.c, eval.c, defs.h: lint and gcc -Wall.
5106 Sun Dec 2 16:45:06 1990 John Gilmore (gnu at cygnus.com)
5108 Merge Intel 960 port of gdb, continuing...
5110 * dbxread.c (partial_symbol_file_open, partial_symbol_file_read,
5111 symbol_file_command): Pass from_tty arg to hush 'em up.
5113 * coffread.c (symbol_file_command): Avoid output if from_tty != 1.
5114 Add magic numbers for 960 COFF format.
5116 Fri Nov 30 09:18:20 1990 John Gilmore (gnu at cygnus.com)
5118 Merge Intel 960 port of gdb, from Intel "1.2" release.
5120 CHANGE_LOG entries from their port, which was based on
5123 Thu Sep 6 11:02:22 PDT 1990
5124 Remove temp file if download is interrupted.
5126 Wed Aug 1 09:08:33 PDT 1990
5127 Now uses binary protocol to talk to NINDY.
5128 Old hex protocol (NINDY 2.13 and older) supported with -O switch.
5129 Times out after 5 seconds when trying to talk to NINDY.
5131 Tue May 29 12:54:49 PDT 1990
5132 Added variable baud rate (-b switch).
5133 Source code reorganization.
5135 Thu Apr 26 11:09:55 PDT 1990
5136 More cleanup of batch mode; specifically, execute "-s", "-e", and
5137 "-se" switches as soon as they are encountered on the invocation line.
5139 Fri Apr 20 13:47:15 PDT 1990
5142 Thu Apr 19 09:54:28 PDT 1990
5143 Add 'reset' command.
5145 Wed Apr 18 09:48:07 PDT 1990
5146 After opening remote tty, wait for 1 second to go by without input
5147 from it before trying to talk to NINDY (fixes problems with the
5148 Heurikon HK80/V960E).
5150 Mon Apr 4 16:33:05 PDT 1990
5151 Some output was not being suppressed in 'batch' mode.
5153 Thu Mar 22 15:31:11 PST 1990
5154 Ask user if old symbol table should be deleted when new file is
5157 Allow user to run a program downloaded before gdb960 was brought up.
5159 Correct "exec-file" help message for i80960 context.
5161 Correct bug in calculating user space address: could occasionally
5162 corrupt user program.
5164 Make sure to zero low-order bits in rip's because of bug in 960CA
5165 A-step part: could cause operation faults when "next"ing across
5168 Correct bug that made it impossible to get source line numbers for
5169 code loaded at addresses higher than 0x7fffffff.
5171 Wed Jan 10 12:43:22 PST 1990
5172 Open remote tty for exclusive use.
5174 Fri Jan 5 12:14:42 PST 1990

5176 opcode for sysctl is 0x659
5178 Mon Oct 23 12:03:04 PDT 1989
5179 Use G960BASE and G960BIN environment variables to find 'sx' utility.
5181 Mon Oct 16 14:15:09 PDT 1989
5182 "sfr0"-"sfr31" should have been named "sf0"-"sf31"
5184 Mon Oct 2 15:56:31 PDT 1989
5186 Added 960CA disassembly support.
5188 To simplify maintenance:
5189 - eliminated use of symblic links on pinsn.c: use i960-pinsn.c
5191 - eliminated opcode.h: incorporates tables into i960-pinsn.c
5192 - moved 960-specific routines from i960-pinsn.c to i960-md.c
5193 - made disassembly interface identical to that in gdmp960.
5197 Wed Nov 28 21:32:48 1990 John Gilmore (gnu at cygint)
5199 * target.h: Allow targets to stack. Add target_has_memory,
5200 _registers, etc. Restructure memory access and "info files"
5201 to walk the target stack.
5202 * exec.c, core.c, inftarg.c, remote.c, remote-vx.c, remote-eb.c,
5203 target.c: Change tables to match target.h.
5204 * inflow.c (child_mourn_inferior): pop child_ops.

5208 * remote-eb.c: New memory regime, new info files.
5209 * remote-vx.c: New memory regime, new info files. Now use
5210 separate targets for VxWorks attachment to machine, and
5211 actually running a process under VxWorks, since one has
5212 stack & execution & regs and the other doesn't.
5213 * remote.c: New memory regime, new info files.
5214 * sparc-xdep.c (fetch_core-registers): New memory regime.
5215 * target.c: New routines and support for stacked targets,
5216 new memory regime, new info files regime.

5220 including use of the new BFD (binary file) library.
5221 * gdbcore.h: Add struct section_table.
5222 * exec.c (build_section_table): Iterate all sections and
5223 record what gdb needs to know about them.

5230 * dbxread.c: Quick changes to make it compile with new BFD.
5231 * utils.c (error): Avoid using bfd_error in generic routines.
5233 * core.c (core_fetch_registers): Get from the ".regs" section of
5235 * sparc-xdep.c (fetch_core_registers): Use the .regs info.
5237 * inferior.h (attach_flag): Export.
5238 * infcmd.c (run_command): use new target_create_inferior.
5239 * infrun.c (child_create_inferior): Don't return result.
5240 * Makefile.dist (VERSION): 3.91.4.
5242 Fri Nov 23 28:15:38 1990 John Gilmore (gnu at cygint)

5245 since been deleted, such as temporary breakpoints.
5246 infcmd.c (program_info): ditto.
5248 * core.c (core_file_command): Display the frame where the core
5253 * remote-vx.c (target_command): Merge in target command from
5254 targ-vx.c. A few other cleanups.
5256 * TODO, Projects: Lots more stuff to do...
5258 Fri Nov 23 18:15:38 1990 John Gilmore (gnu at cygint)
5260 Massive changes to wall off the remote-debugging interface
5261 behind a function vector. The port to handle VxWorks targets
5262 is also part of this.
5264 All files: Replace references to renamed functions,
5265 remove references to remote_debugging, remove references to
5266 have_include_file, have_core_file in favor of target_has_stack,
5267 target_has_memory, etc.
5269 * Modularize the breakpoint interface.
5270 breakpoint.h (BREAKPOINT_MAX): New define sets max length of
5271 a breakpoint instruction.
5272 breakpoint.c: struct breakpoint's shadow_contents now sized as
5274 (insert_breakpoints): Vector to target to install breakpoints.
5275 (remove_breakpoints): Vector to target here too.
5276 Remove REMOTE_SA_SPARC kludges and other remote_debugging.
5277 sparc-tdep.c (single_step): Use new breakpoint interface for
5278 the single-step breakpoints.
5279 mem-break.c (memory_insert_breakpoint, memory_remove_breakpoint):
5280 New file, contains routines to insert and remove breakpoints by
5281 reading out the old contents and later replacing them. This is
5282 how ptrace breakpoints work, and many remote systems as well.
5284 * tm-vxworks68.h: New config file, overrides a few things for
5285 Wind River's preferences.
5287 * target.h: New file, for transfer vector used to talk to the
5288 inferior (child, attached, core, exec, remote, etc). All accesses
5289 to the thing being debugged should come through these vectors.
5290 target.c: New file, routines to handle transfer vector.
5291 (various files): Add transfer vectors XXX_ops for the various
5292 targets and pseudo-targets (core files, etc) we support.
5294 * breakpoint.c (bpstat_stop_status): Further explorations of
5295 watchpoints and why things don't work all the time.
5296 (bpstat_alloc): New fn to allocate a bpstat and chain it.
5298 * config.gdb: Only add "source ${srcdir}/.gdbinit" to
5299 the local gdbinit if it doesn't already have it.
5301 * core.c (core_ops): add and install.
5302 Allow core debugging without exec file.
5304 * dbxread.c (free_and_init_header_files): Merge two fns.
5305 (end_symtab): Free named symbol table when a new version comes in.
5306 (read_dbx_symtab): Relocate all kinds of symbols with base
5307 address. First step toward handling different text, data, bss
5309 (add_file_addr_command): Renamed add_file_command.
5310 (add_file_command): Vector to remote handler.
5311 Add "load" as an alias for "add-file" command.
5313 * defs.h: Allow "volatile" to be used in non-ANSI; use it for
5314 non-returning functions.
5316 * exec.c: Add exec_ops, and push it as a target when an exec
5319 * infcmd.c (run_command): Pass executable file name and arg list
5320 separately when starting an inferior. Permit "run" when no exec
5321 file is specified, for VxWorks.
5322 (detach_command): Move to child_detach in inftarg.c.
5324 * inftarg.c: New file. Unix-child-specific routines, and the
5325 child_ops structure.
5327 * inferior.h (registers): Export "registers" as the way for
5328 target dependent register handlers to find gdb's local copy of
5329 the registers. Rename "stop_after_attach" to "stop_soon_quietly"
5330 since it is now used by places that want wait_for_inferior to
5331 handle the grunge but want to see every trap from the inferior.
5333 * inflow.c (create_inferior): Pull out, and merge into infrun.c.
5334 Eliminate remote_debugging hooks in terminal handling.
5336 * infrun.c: Replace start_inferior with child_create_inferior.
5337 Move all the hair of Unix shells and ptrace idiosyncracies into
5338 child_create_inferior, so remote handlers don't have to deal.
5339 Remove running_in_shell. Rename stop_after_attach to
5340 stop_soon_quietly, and use it in a few other places where we want
5341 to just call wait_for_inferior and get control back on the first
5342 trap. trap_expected now never takes a value > 1.
5343 (init_wait_for_inferior): Initialize static vars when a new
5346 main.c (gdbinit): Add new hook for .gdbinit file name, let
5347 it be overridden by config files as GDBINIT_FILENAME.
5348 (DEFAULT_PROMPT): Add new hook for overriding (gdb) prompt.
5349 Both of these are used for VxWorks gdb.
5351 mcheck.c: rename include file "gmalloc.c" to avoid problems
5352 with system include file "malloc.c".
5354 param-no-tm.h: New include file, same as param.h but does not
5355 include the default "tm.h" file. This is used in files where
5356 the target is known, e.g. remote-eb.c or sparc-xdep.c.
5358 param.h: Now just a shell that includes tm.h and param-no-tm.h.
5360 remote-vx.c: New file, VxWorks remote debugging support. Uses
5361 RPC routines that are shared with the target system, in directory
5364 remote.c: Vectorize remote interface.
5366 source.c: Globalize source_path, and make an alias "l" for "list"
5367 since we now have the "load" command.
5369 sparc-xdep.c: Use new param-no-tm.h.
5371 symmisc.c (free_named_symtab): Add new function from Wind River.
5372 However, ifdef it out for now while we think about what it should
5375 tm-sun3.h, xm-sparc.h, xm-sun3.h, xm-symmetry.h: Move
5377 the xm- file, and change its name to CHILD_PREPARE_TO_STORE, since
5378 non-Unix-children handle this with their own code in the target
5381 Makefile.dist: Roll version to 3.92.3. Add vx-share stuff to
5382 source and target lists. Add vx-share to default list of include
5383 directories. Add new files to src and target lists: mem-break,
5384 target, inftarg, remote-eb, remote-vx, targ-vx. Be sure the
5385 ${srcdir} versions of munch and createtags are used.
5387 * valops.c (find_function_addr): Split out of call_function.
5388 (call_function_by_hand): Rename call_function; this function
5389 calls functions in the target by laboriously patching the target
5390 word-by-word with the right stack, args, regs, etc.
5393 Mon Nov 5 17:29:10 1990 John Gilmore (gnu at cygint)
5395 Handle AMD 29000 a bit better.
5397 * remote-eb.c (readchar): Mask received char log to make it readable.
5398 (remote_start): Pass arguments down to executing program.
5399 Make startaddr unsigned.
5400 infrun.c (start_inferior): Accept args, pass them to
5402 infcmd.c (run_command): Pass args down to start_inferior.
5404 * tconfig/am29k-aout, tconfig/am29k-coff: New files specifying
5405 the target object file format.
5406 tm-29k.h: Pay heed to COFF_ENCAPSULATE.
5408 * am29k-pinsn.c (print_insn): Print 0x on hex numbers in disassembly.
5409 am29k-tdep.c (examine_prologue): Better checking of function prefixes.
5411 Sun Oct 7 18:20:45 1990 John Gilmore (gnu at cygint)
5413 * Makefile.dist (VERSION): Roll version to 3.91.9 and freeze.
5414 * TODO: We did a few things, we have more to do though.
5416 * xm-sparc.h (CLEAR_DEFERRED_STORES): Define.
5417 * inflow.c (inferior_died): Clear deferred stores.
5419 * Debug problems with dummy frames and calls to the inferior.
5420 * tm-sparc.h (PUSH_DUMMY_FRAME, POP_FRAME): Move to sparc-tdep.c.
5421 * sparc-tdep.c (do_restore_insn): Simplify.
5422 (sparc_frame_find_saved_regs): Simplify and fix what we find.
5423 (sparc_push_dummy_frame): Simplify and fix what we push.
5424 (sparc_pop_frame): Slightly more hair here, deciding whether
5425 we are restoring a saved PC or returning to a return address in %i7.
5426 * sparc-xdep.c (read_inferior_registers): Debug if valid reg is read.
5428 * utils.c (xmalloc, xrealloc): Return type depends on __STDC__.
5429 * symtab.h (xmalloc): ditto, for obstack_chunk_alloc.
5430 * obstack.h (chunkfun): ditto.
5431 * defs.h (xmalloc, xrealloc): ditto
5433 * utils.c (quit): Grab the terminal from the child if necessary.
5435 * inflow.c (term_status_command): Rename to term_info, change
5438 * sparc-pinsn.c (print_insn): Disassembly prefers real instructions.
5439 (is_delayed_branch): Speed up.
5440 * sparc-opcode.h: Add ALIAS bit to aliases. Fix up opcode tables.
5441 Still missing some float ops, and needs testing.
5443 * Support for input and output radixes other than base 10
5444 * defs.h (input_radix, output_radix): Declare.
5445 * expread.y (yyparse, parse_number): Handle changes of input
5446 radix, and ambiguous names-or-numbers in radixes >10.
5447 * printcmd.c (print_scalar_formatted): Print formatted hex
5448 numbers in varying column widths.
5449 * valprint.c (val_print): Use output_format to print scalar ints.
5450 (set_input_radix, set_output_radix, set_radix): Create.
5451 (set_output_radix): Set output_format from output_radix.
5452 (_initialize_valprint): add `set radix' but leave the others off.
5454 * main.c (execute_command): Let stupid questions be turned off.
5455 (_initialize_main): Handle "set stupidity", etc.
5457 * main.c, inflow.c, inferior.h, frame.h, command.c, defs.h,
5458 sparc-pinsn.c, sparc-xdep.c, value.h, valops.c, values.c: Lint.
5460 Tue Oct 2 11:20:02 1990 John Gilmore (gnu at cygint)
5462 * TODO, Makefile.dist, ChangeLog: Freeze for 3.91.8 release.
5463 bfd stuff is still screwed up, but with some manual work, it
5466 * breakpoint.c (bpstat_do_actions): Start over if a command
5467 proceeds the inferior, since the inferior will have stopped and
5468 will need to have its new stop-actions taken care of.
5470 * dbxread.c (read_struct_type): Expression gives Sun3 4.0.3
5471 compiler fits, simplify it.
5473 * gdb.texinfo (directory command): Doc new dir command.
5474 source.c (directory_command): "dir" now puts things on the front
5475 of the path, moves dups up front, and handles multiple names
5476 on the command line, inserting each one in order. It also
5477 blows away cached line and full_filename info.
5479 * stack.c (backtrace_command): Skip "more stack frames follow"
5482 * Change #ifndef HAVE_VPRINTF to #define MISSING_VPRINTF in
5483 xm-convex.h, xm-hp300bsd.h, xm-isi.h, xm-merlin.h, xm-news.h,
5484 xm-np1.h, xm-pn.h, xm-pyr.h, xm-symmetry.h, xm-umax.h, xm-vax.h.
5485 The only odd one was Gould NP1, which had defined vprintf to
5488 * Merge Ted Goldstein <tedg@Eng.sun.com>'s changes for epoch.
5489 printcmd.c (print_command_1): Pass 'inspect' flag down as a global
5490 variable, inspect_it.
5491 valprint.c (print_string, val_print): Use the global inspect_it
5492 to indicate whether to print in Epoch style or normal style.
5494 Mon Oct 1 23:55:26 1990 John Gilmore (gnu at cygint)
5496 * printcmd.c (call_command): add an alias for the "print" command
5497 which runs expressions and doesn't print the result if void.
5498 (print_command_1): implement it.
5500 * command.c: Remove #if 0'd code. Initialize all the fields
5501 in add_cmd (). Rename do_nothing_command to
5502 not_just_help_class_command, and make it externally visible.
5503 command.h: add user_commands to struct.
5504 * main.c (define_command): Don't overload c->function with a char
5505 string as well as a function pointer.
5507 * eval.c (evaluate_subexp): Reinstall tiemann changes to
5508 calling convention of value_struct_elt () that got dropped in
5511 * tm-sparc.h (FRAME_FIND_SAVED_REGS): move to sparc-xdep.c.
5512 sparc-tdep.c (sparc_frame_find_saved_regs): ditto.
5514 * tm-sparc.h (POP_FRAME): replace some constants with defines.
5516 * sparc-xdep.c (store_inferior_registers): defer stores to regs
5517 until a good time (e.g. when we are about to run the child),
5518 saving ptrace calls.
5519 * infrun.c (proceed): handle DO_DEFERRED_STORES.
5520 * tm-sparc.h: define DO_DEFERRED_STORES.
5522 * sparc-xdep.c (store_inferior_registers): when storing float
5523 registers, don't store stack regs too. When storing the SP,
5524 however, DO store the stack regs too. This fixes a bug in which
5525 the dummy frame is not recognized when a call_function finishes,
5526 because its frame pointer (in the stack regs) was never
5528 (read_inferior_registers): Mark WIM and TBR and FPS and CPS valid
5529 even though we don't know how to read them from an inferior.
5530 valops.c (call_function): Comment about storing SP.
5532 * infrun.c (save_inferior_status): Save away the original bpstat
5533 chain so it can be restored later. Install the copied version for
5534 use by whoever saved the status. It will be blow away by
5535 restore_inferior_status, and the original chain restored. This is
5536 important for people who have pointers into the original.
5538 * breakpoint.c, command.h, copying.awk, dbxread.c, defs.h,
5539 findvar.c, frame.h, obstack.h, obstack.c, inflow.c, value.h,
5540 main.c, printcmd.c, sparc-tdep.c, symtab.c, valprint.c: lint
5543 Fri Sep 28 20:32:46 1990 John Gilmore (gnu at cygnus.com)
5545 * Makefile.dist: Roll version to 3.91.8. Add bfd.h and bfdconfig.h
5546 temporarily to the makefile. Add am29k-opcode.h and WHATS.NEW.
5547 Add stuff.c and kdb-start.c to the OTHERS list for tar files.
5549 Fri Sep 28 19:12:12 1990 John Gilmore (gnu at cygint)
5551 * Merge Mike Tiemann's multiple inheritance changes from Sun.
5552 Store the baseclasses in a type struct starting from array element
5553 0 rather than from the unusual array element 1.
5555 dbxread.c: the above.
5556 (virtual_context): Add
5557 Read new debug information about which virtual function table
5558 a virtual function is from, and store it in fn_field.fcontext.
5560 symtab.h: Add fcontextt. Fix baseclass indices. Typo in
5561 TYPE_FN_FIELD_STATIC_P.
5563 symtab.c: the above.
5564 valops.c: the above. Handle pointer casts of object *'s.
5565 (search_struct_method): Add.
5566 (value_struct_elt): First arg is now a pointer to a value, and is
5569 valprint.c: the above.
5570 values.c (value_virtual_fn_field): Add type arg. Handle
5571 offsetting to the proper object when calling virtual fns.
5573 (baseclass_addr): Add valuep arg.
5575 * README: Document the current state of BFD config (missing).
5576 * TODO, ChangeLog, Makefile.dist: Roll version.
5577 * WHATS.NEW: Add summary of changes since 3.5.
5579 Thu Sep 27 16:23:12 1990 John Gilmore (gnu at cygint)
5581 * dbxread.c (read_struct_type): Clear bit vectors whenever
5583 symtab.c (B_CLRALL): define.
5585 * tm-sparc.h (STORE_RETURN_VALUE): Avoid clobbering types by
5586 using == rather than =. Huh... This fixes the dreaded problem
5587 wherein builtin_type_int becomes TYPE_CODE_FLT.
5589 * core.c (info_files): Show the inferior pid.
5591 * config.gdb: Avoid putting "dir" command into .gdbinit. GDB
5592 already knows how to look in the source directory.
5594 * Remove psymtab hair from many places. Remove duplicated code
5595 for searching symbol tables. Hide psymtabs from most places.
5596 Make it fast to get from a psymtab to its symtab.
5598 blockframe.c (blockvector_for_pc): Remove psymtab hair.
5599 coffread.c (psymtab_to_symtab): Rename to psymtab_to_symtab2.
5600 mipsread.c (psymtab_to_symtab): Rename to psymtab_to_symtab2.
5601 dbxread.c: export psymtab_to_symtab, make it work if called N times.
5602 (psymtab_to_symtab): Rename to psymtab_to_symtab2. Initialize
5603 new symtab completely. New psymtabs get symtab pointer
5604 initialized to zero. Remove MI warning printf.
5605 symtab.h: Comments. Add psymtab to symtab pointer.
5606 (PSYMTAB_TO_SYMTAB): New macro.
5607 symtab.c: use PSYMTAB_TO_SYMTAB. Add psymtab_to_symtab and export it.
5608 source.c: use PSYMTAB_TO_SYMTAB. Remove symtab version and
5610 stack.c (backtrace_command): Avoid pre-pass to read symbols, if
5612 (print_frame_info): Avoid special-casing symbols that have not yet
5615 * source.c (open_source_file): Quick path if we have already
5616 located the source file by its full name.
5618 * symtab.c (lookup_symbol): Use find_pc_symtab rather than
5619 find_pc_psymtab. When a name is found in the misc function
5620 vector, search the symbol table for its mangled name, not the
5621 name that the user typed.
5623 * bfd.h: Fix missing comment terminators, make #endifs match.
5625 * valarith.c (value_less): Handle unsigned int comparisons.
5626 Add FIXME about pointer compares, which assume host and target
5627 pointers are the same.
5629 * command.c (do_nothing_command): lint
5630 dbxread.c: lint. Remove sort_syms. Document C++ visibility info,
5631 fix comments on debug symbol format for visibility. Actually set
5632 visibility of symbols.
5633 main.c (echo_command): lint; use <readline/history.h>.
5634 tm-sparc.h (FRAME_FIND_SAVED_REGS): lint
5635 obstack.h (_obstack_blank): Rearrange pointer math to avoid
5636 pointing past end of allocated memory; saber complains.
5637 obstack.h: Declare the external functions that we use.
5638 valarith.h: use <string.h>
5639 solib.c (solib_add): lint.
5641 Fri Sep 21 17:05:19 1990 John Gilmore (gnu at cygint)
5643 * main.c (initialize_main): Default info_verbose to off, now that
5644 symbol reading is fast.
5645 (quit_command): Avoid clobbering exec_bfd while quitting.
5647 * Initial BFD (binary file diddling library) merger:
5648 coffread.c: Change AOUTHDR to struct exe_hdr.
5650 core.c: initialize initialized data at compile time.
5651 (core_file_command): Move from coredep.c, convert to bfd.
5652 (xfer_core_file): Convert to bfd.
5653 exec.c (exec_file_command): use bfd routines.
5655 mips-tdep.c: Remove exec_file_command and friends.
5658 * coredep.c: (fetch_core_registers) Convert core_file_command to
5659 fetch_core_registers.
5660 mips-xdep.c, sparc-xdep.c, sun3-xdep.c: ditto.
5662 * utils.c: (error): Bogus crap, FIXME, to print bfd errors.
5663 (my_bfd_read): More bogosity, which I don't think we call.
5664 (program_name): Remove this atrocity asap!
5666 Wed Sep 19 13:36:41 1990 John Gilmore (gnu at cygint)
5669 values.c: allocate_repeat_value was not clearing the
5670 optimized_out field.
5671 (value_static_field): minor stylistic fix (wrong macro was used).
5672 valops.c (value_struct_elt_for_address): didn't work for C++
5675 * signame.c (_initialize_signame): Initialize signal names once.
5677 * breakpoint.h, command.c, copying.awk, defs.h, environ.c,
5678 exec.c, frame.h, infcmd.c, inferior.h, main.c, munch, sun3-xdep.c,
5679 symtab.h, tm-29k.h, valprint.c, value.h, values.c: Lint.
5681 * remote-eb.c: Support user-settable baud rates on the serial port.
5683 * tm-sun3.h (PREPARE_TO_STORE): fix typo.
5685 Fri Sep 14 13:28:29 1990 John Gilmore (gnu at cygint)
5687 * tconfig/sun3os4: Remove warning about native assembler,
5688 since it also occurs in the xconfig file.
5690 * findvar.c (registers): Allocate some slop after `registers'
5691 to prevent stray accesses from trashing the next variable.
5693 * tm-68k.h (REGISTER_BYTES): Allocate the right number of bytes
5694 on the sun-3, by changing the #ifdef from `sun3' (which is not
5695 defined by cc) to `sun'. Symptom was trashed builtin_type_XXX
5696 vars, which happened to follow `registers' in the executable.
5698 * readline/history.c (history_search): Heed gcc-2's advice
5699 and parenthesize && inside ||).
5701 * am29k-opcode.h, am29k-pinsn.c, am29k-tdep.c, remote-eb.c,
5702 tm-29k.c: Insert FSF copyright headers.
5704 * remote-eb.c: Better comments.
5706 * Makefile.dist: Update to 3.91.6.
5707 * TODO: note PREPARE_TO_STORE problem.
5709 Thu Sep 13 09:52:33 1990 Jim Kingdon (kingdon at cygint)
5711 * stack.c (frame_info): Only use FRAME_FIND_SAVED_REGS if defined.
5713 * remote.c: Wrap the whole file in #if !defined (SPECIAL_REMOTE).
5715 * infrun.c (wait_for_inferior, at end): Don't set up
5716 prev_* if the inferior no longer exists.
5718 * inferior.h (CALL_DUMMY_LOCATION): New macro, to replace
5719 CANNOT_EXECUTE_STACK.
5720 valops.c (call_function): Use it.
5722 * tm-convex.h: Add CALL_DUMMY_LENGTH for use by PC_IN_CALL_DUMMY.
5724 * inferior.h (PC_IN_CALL_DUMMY): New macro.
5725 infrun.c (wait_for_inferior, 2 places): Use it.
5727 * values.c (value_being_returned): Only use
5728 EXTRACT_STRUCT_VALUE_ADDRESS if defined.
5730 * Move PREPARE_TO_STORE from xm-sun3.h to tm-sun3.h to do the
5731 right thing for remote-eb.c.
5733 * sun3-xdep.c: Remove extraneous call to remote_store_registers.
5734 * sun386-xdep.c, hp300hpux-xdep.c, sparc-xdep.c: Ditto.
5736 * blockframe.c: Put get_frame_saved_regs inside #if !defined
5737 (FRAME_FIND_SAVED_REGS).
5739 * findvar.c ({fetch,store}_registers): Check for
5740 REMOTE_{FETCH_STORE}_REGISTER macro.
5742 * findvar.c (get_saved_register): Add argument lval and
5743 change meaning of argument addr.
5744 findvar.c: Change calls to get_saved_register to reflect
5745 new calling convention.
5746 valops.c (value_assign): Use get_saved_register instead of
5747 find_saved_register.
5749 Sun Sep 2 12:40:20 1990 Jim Kingdon (kingdon at cygint.cygnus.com)
5751 * coffread.c (read_one_sym): Make temp_aux an AUXENT, not
5752 an (uninitialized) pointer to one. Use "&" when passing it
5755 Fri Aug 31 22:57:54 1990 Jim Kingdon (kingdon at cygint.cygnus.com)
5757 * coffread.c (getfilename): Use DGUX x_offset and x_name if
5760 * coffread.c (symbol_file_command): Put semicolon after
5762 Put safe_to_init_tdesc_context in #if defined (TDESC).
5763 Put #ifdef TDESCs in 1st column for non-ANSI cpp's.
5764 coffread.c: #include <sys/stat.h>.
5765 (read_coff_symtab): Typo: in_source_files -> in_source_file.
5766 Add missing ')' in check for "lc%" and friends. Remove
5768 Declare read_one_sym() at top of file.
5769 (read_file_hdr): Put in extra #ifdefs so MC68MAGIC and
5770 MC68WRMAGIC can have the same value without causing a duplicate
5773 Thu Sep 13 15:55:36 1990 John Gilmore (gnu at cygint)
5775 * Allow a Makefile to be built without building the
5776 tm and xm file links that screw up builds in subdirectories.
5777 This is done with `config.gdb none', then you can do things
5778 like `make gdb.tar.Z'.
5779 * tconfig/none: Config file for no target system
5780 * xconfig/none: Config file for no host system
5781 * config.gdb: If no TM or XM files are called out by the
5782 host or target file, don't make links for them.
5784 * cplus-dem.c: Add documentation.
5786 * dbxread.c (read_ofile_symtab): Turn a fatal error into a
5787 simple error, so the user's gdb doesn't crash due to some object
5788 file problem (e.g. somebody is rebuilding the file out from under
5791 * printcmd.c (print_address_symbolic): demangle the symbol.
5793 * Makefile.dist (OTHERS): Remove tdesc-lib because it has
5794 Motorola copyrights in it. Make "make gdb.tar.Z" work.
5795 (alldeps.mak): sort and uniq all results from this; duplicates
5796 hose gdb.tar.Z link building. Remove RCS files from
5797 tconfig and xconfig. Add config files for sun386. Add
5798 a few odd files to OTHERS and HFILES.
5800 Mon Sep 10 21:20:24 1990 John Gilmore (gnu at cygint)
5802 * Makefile.dist: Pull solib.c to tconfig/sun?os4.
5803 Roll version number to 3.91.5. Make lint work in bindir.
5805 * README: Document cross-debugging and new file structure.
5807 * blockframe.c: Lint. Include "value.h" to declare read_register.
5808 (find_pc_partial_function): remove duplicate line.
5810 * command.h: Lint. Declare error_no_arg and dont_repeat.
5812 * tm-news.h: Remove inadvertently duplicated stuff.
5814 * mipsread.c: Remove cache_pc_function stuff, now done cleanly.
5815 Clean up usage of misc_function_type. Declare some CORE_ADDRs.
5817 * config.gdb: Allow `config.gdb host target' form. Clean
5818 up previous change that printed bogus messages when you just said
5821 * core.c: #include "command.h" for lint.
5824 * main.c: Remove some casts of enums. Lint.
5831 * printcmd.c (initialize_printcmd): Fix thinko in inspect cmd.
5833 * sparc-tdep.c (isannulled): Take instruction as parameter, don't
5834 read it from memory. This will allow us to save ptrace calls
5835 eventually. Changed caller single_step too.
5837 * sparc-xdep.c (fetch_inferior_registers): Avoid reading regs
5838 that we aren't going to use, saving many ptrace calls, especially
5839 when watchpointing or single stepping. Use some #define's for
5841 (store_inferior_registers): Ditto.
5842 (core_file_command): Use some #define's for constants.
5844 * tm-sparc.h: Add #define's for some register numbers, so we
5845 can eliminate the use of random constants in sparc-xdep.c.
5847 * stack.c (frame_command, print_frame_info, up_command,
5848 down_command) Remove frame_changed, since it
5849 causes a bug and doesn't seem to do anything useful. In some
5850 places it was used as a flag, in others as a stack level (?).
5852 * utils.c: Use MISSING_VPRINTF rather than HAVE_VPRINTF, so the
5853 default is to use the portable (vprintf) version rather than the
5855 * xm-news.h (MISSING_VPRINTF): Add.
5857 * valprint.c (val_print): Demangle fancy vtbl printouts. Lint.
5859 Sat Sep 8 00:24:12 1990 John Gilmore (gnu at cygint)
5861 * Remove stuff that forces -Bstatic linking of gdb, and warnings
5862 about linking debugged programs -Bstatic in the sun?os4 config
5863 files in tconfig and xconfig subdirectories.
5865 * main.c (main): Remove unreached exit(0) now that we exit
5868 * Create TODO file for online bug list. There are too many
5869 "little" bugs to keep track of on paper.
5871 * Change Projects file to refer to bug-gdb@cygnus.com
5872 rather than kingdon@ai.
5874 Fri Sep 7 23:35:15 1990 John Gilmore (gnu at cygint)
5876 * Makefile.dist (VERSION): 3.91.4 now.
5878 * symtab.c (init_misc_bunches): Rename from init_misc_functions.
5879 (condense_misc_bunches): Add sanity check that misc_count is
5880 the same as the number of symbols in the bunch.
5882 * coffread.c: rename init_misc_bunches. Pass an argument
5883 to condense_misc_bunches (a zero).
5885 * dbxread.c (partial_symbol_file_read): Call init_misc_bunches
5886 every time we are called; don't rely on our caller to do it.
5887 (add_file): Remove call to init_misc_bunches.
5889 * mipsread.c: Only warn, don't error, if unknown symbol types.
5890 This keeps an old gdb from falling on its face if it sees newly
5891 extended symbol info. Rename init_misc_bunches.
5893 Fri Sep 7 22:58:15 1990 John Gilmore (gnu at cygint)
5895 * Merge in changes from Per Bothner for DECstations and other
5896 MIPS stuff. The rest is Bothner speaking:
5898 The next message is a merger of Alessando Forin's mips port with
5899 mine. I've tried to use my good if biased judgment to get
5900 the best of both. It *does* need testing.
5902 Some of the changes are general, *not* mips-specific.
5905 Didn't believe in little-endian bit order.
5906 There are still inconsistencies about whether flags
5907 like BITS_BIG_ENDIAN are integer (#if ...) or
5908 boolean (#ifdef ...). I tried to paper over them.
5910 dbxread.c,coffread.c,mipsread.c,symtab.c,symtab.h:
5911 Moved some misc_function code that was common to
5912 {dbx,coff,mips}read.c to symtab.c.
5913 In the process, I think I cleaned things up a bit.
5914 At the same time, moved obsavestring and obconcat to symtab.c.
5917 Removed obsolete condense_addl_misc_bunches (use
5918 condense_misc_bunches(1) instead).
5921 Needed to include <sys/dir>, at least on DECstations.
5923 valops.c, mips-tdep.c, tm-mips.h:
5924 Added PUSH_ARGUMENTS macro to support funny argument-pushing
5925 conventions (when STACK_ALIGN is insufficient).
5926 Needed on mips, where doubles need 8-byte alignment,
5927 but ints only need 4.
5930 Removed cruft that was not being used.
5931 Merged in many fixes (most from Frank Yellin, fy@lucid.com).
5934 Print $ before register-names (I think that makes things a little
5936 Never print two instructions, even if one delays.
5937 Removed hex-disassemble set_cmd. (This is not mips-specific,
5938 so I think the argument is whether it is generally worthwhile or not.
5939 I'm inclined to think not, given how easy it is to
5940 convert between radixes in gdb.)
5943 This is basically Alessando's code.
5944 It doesn't use obstacks; I changed it to use obstacks
5945 in a few minor places where using malloc causes a
5946 memory leak. (Probably, more places could/should be changed.)
5947 I added record_misc_function where it was missing.
5948 In symbol_file_command and add_file_command, I tried
5949 to make the code consistent with more recent versions.
5950 Minor sylistic changes in parse_procedure.
5951 Make a .gdbinfo. psuedo-symbol point back to the real
5952 procedure symbol (using the isym field).
5955 This is basically from my port, but with a lot of details
5956 and a number of routines merged in from Alessando's version.
5957 I basically used my code "raw" backtrace (use heuristics
5958 from the actual code, rather than symbol table info) - though
5959 the idea is Alessandro's. I feel my code is a little cleaner
5960 here, particularly in being a little more flexible, such as being
5961 able to handle gcc-produced code (which it now can).
5962 It also doesn't do frame caching (which is not useful
5963 more recent gdb versions).
5964 I also used my code for push_/pop_dummy, more or less.
5965 I tried to incorporate AF's code for testing sigtramp
5966 while backtracing; I probably got it wrong.
5967 Added mips_print_register, which tries to scrunch as much
5968 information as possible on a screen...
5969 Removed the skip-prologue set_cmd. As with hex-disassemble (see
5970 under mips-pinsn.c), I don't see anything mips-specific here,
5971 and I don't see it being all that useful anyway.
5974 Added a $fp psuedo-reg distinct from $fp (nice for gcc).
5975 Use more register names (rather than hard-cases numbers).
5977 Thu Sep 6 18:33:15 1990 John Gilmore (gnu at cygint)
5979 * Hack up 3.90.11 changes:
5981 * Makefile.dist (depend): parameterize $(GCC).
5982 Add solib.c and solib.o.
5983 (readline): Fix vpath for both absolute or relative SRCDIR.
5985 * blockframe.c: Fix from Schaefer@asc.slb.com for shared libs.
5986 Also, let the part I didn't understand at least compile so
5987 I can test the rest. FIXME.
5989 * dbxread.c: Fix thinko using strcmp.
5990 (init_psymbol_list): declare static.
5991 (partial_symbol_file_open): Comment cleanups better, avoid
5992 cleaning up the string table since the caller will do that.
5993 Move the stat for mod time into symbol_file_command, temporarily.
5994 (There should be a mod time for each symbol file, eventually,
5995 to control its rereading. FIXME.)
5997 * infptrace.c (PT_WRITE_D): use same value as PT_WRITE_I for
5998 SunOS, which gives error for shared libs otherwise. (From
5999 Schaefer, probably FIXME needs work for portability.)
6001 * solib.c: Move #include "param.h" to work.
6002 Lowercase all the Uppercase Letters In the Messages.
6003 (find_solib): Clean up inferior_so_name for debug printouts.
6004 Allow no argument, to mean all shared libraries.
6006 * symmisc.c: include param.h to get CLEAR_SOLIB.
6008 Wed Sep 5 18:00:08 1990 John Gilmore (gnu at cygint)
6010 * Merge in Kingdon's changes from FSF: the diffs from 3.90.9
6011 to 3.90.11. ChangeLog entries below are from this.
6013 Wed Jun 13 09:17:39 1990 Jim Kingdon (kingdon at mole.ai.mit.edu)
6017 * Makefile.dist (HFILES): Add tm-sunos.h.
6019 Tue Jun 12 16:15:26 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
6023 * Makefile.dist (gdb.tar.Z): Change linking of config so it works.
6025 Thu Jun 7 16:22:27 EDT 1990 Jay Fenlason (hack@ai.mit.edu)
6027 * sparc-opcode.h Added single-operand version of rett.
6029 Mon Jun 4 18:12:31 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
6031 * m-sparc.h (REG_STRUCT_HAS_ADDR, STRUCT_ARG_SYM_GARBAGE):
6032 Put parens around gcc_p in expansion.
6034 Thu May 24 15:44:51 1990 Jim Kingdon (kingdon at mole.ai.mit.edu)
6036 * utils.c (lines_to_list): Return 10 if lines_per_page == 0.
6038 Wed May 23 16:36:04 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
6040 * Changes for Sun shared libraries:
6041 blockframe.c (find_pc_partial_function): If a non-text symbol
6042 is found, set *address = pc - FUNCTION_START_OFFSET.
6043 breakpoint.c (insert_breakpoints) [DISABLE_UNSETTABLE_BREAK]:
6044 Disable breakpoints instead of giving an error.
6045 source.c (select_source_symtab): Initialize cs_pst.
6046 symmisc.c: Call CLEAR_SOLIB if defined.
6047 symtab.h: Make text{low,high} CORE_ADDR not int.
6048 (psymtab): New field addr.
6050 dbxread.c: Move DECLARE_FILE_HEADERS outside functions.
6051 (record_misc_function): Give correct type for N_DATA symbols.
6052 (condense_misc_bunches): do "misc_function_count = j" regardless
6054 Take code which is shared between symbol_file_command and
6055 add_file_command and put it into partial_symbol_file_{open,read}.
6056 Split add_file_command into add_file_command and add_file.
6057 Make psymtab_to_symtab read in the string table if the file
6059 Two new parameters to read_dbx_symtab and start_psymtab.
6060 tm-sunos.h: New file.
6062 Tue May 22 17:43:03 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
6064 * infcmd.c: Change cont_command to continue_command and "cont"
6067 Mon May 21 14:41:41 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
6069 * breakpoint.c (enable_breakpoint): Get value of watchpoint.
6071 * defs.h [sparc]: Use <alloca.h> regardless of __GNUC__.
6073 * values.c (USE_STRUCT_CONVENTION): Check for structures of
6074 size 1,2,4,8 rather than size < 8.
6076 * dbxread.c (dbx_lookup_type): Do f->length *= 2 as many times
6077 as necessary, not just once.
6079 * sparc-opcode.h: Add a bunch of new opcodes which Sun as supports.
6081 Thu May 17 15:04:09 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
6083 * {t,x}m-sun386.h, sun386-xdep.c, {x,t}config/sun386
6085 * tm-news.h: Add CALL_DUMMY_*.
6087 * tm-68k.h: Remove duplicate comment at FRAME_FIND_SAVED_REGS.
6089 * config.gdb: In list_host, list_target, use ${i}, not $i.
6091 Tue May 15 21:27:12 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
6093 * source.c (find_source_lines) [BROKEN_LARGE_ALLOCA]: Use xmalloc.
6095 * sparc-opcode.h: Change all store floating-point state register
6096 instructions to have the right match & lose fields.
6098 Sat May 5 12:39:18 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
6100 * Makefile.dist: Move -I${srcdir} to GLOBAL_CFLAGS and pass
6102 config.gdb: If srcdir != ., create readline directory and
6103 copy a makefile into it.
6105 * wait.h, infrun.c: Change WRETCODE to WEXITSTATUS for
6106 consistency with POSIX.
6108 * breakpoint.c (bpstat_stop_status): Disable watchpoint
6109 when we exit its exp_valid_block.
6111 Tue Sep 4 11:46:46 1990 John Gilmore (gnu at cygint)
6113 * Makefile.dist: Bump version to 3.91.3.
6115 * Clean up handling of breakpoint commands (somewhat).
6116 Prompted by Tiemann bug report "cont 10" doesn't work any more.
6118 inferior.h: Add breakpoint_proceeded to inferior status struct
6119 and globals; save it and restore it.
6120 (clear_breakpoint_commands): Cleanup, remove old #define.
6122 infrun.c (clear_proceed_status): Set breakpoint_proceeded.
6123 (save_inferior_status, restore_inferior_status): handle it also.
6124 (proceed): Remove earlier code that set breakpoint_proceeded.
6125 It is now set only in clear_proceed_status.
6126 (clear_proceed_status): Cleanup, use bpstat_clear rather
6127 than clear_breakpoint_commands. No callers need the stop_bpstat
6128 between clear_proceed_status and proceed.
6130 infcmd.c: Add breakpoint_proceeded definition and comment.
6131 (cont_command, jump_command, signal_command): Move call to
6132 clear_proceed_status right next to call to proceed.
6134 breakpoint.c (bpstat_do_actions): Avoid clobbering our
6135 caller's argument while running down the chain of breakpoints.
6136 Use new variable "breakpoint_proceeded" to determine when
6137 a command that it executes moves the inferior past the
6139 (bpstat_clear): Handle NULL argument.
6140 (bpstat_clear_actions): Avoid useless call to
6141 breakpoint_auto_delete.
6142 (delete_breakpoint): Clean up bpstat's that are pointing to
6143 the deleted breakpoint from the stop_bpstat chain.
6144 (breakpoint_auto_delete): Simplify.
6146 * Clean up handling of EOF, error on stdin, etc. This was
6147 prompted by a network problem that caused gdb to go into an
6148 infinite loop filling up its malloc'd memory.
6150 main.c (return_to_top_level): Cleanup: call bpstat_clear_actions,
6151 not clear_breakpoints_commands, which is now gone.
6152 (main): If command_loop returns (e.g. from EOF on stdin), do
6153 a quit_command (looping back to command_loop if quit_command
6154 doesn't really quit).
6155 (command_loop): check result from command_line_input and
6156 exit if it returns NULL, rather than passing the NULL to
6158 (gdb_readline): Free malloc'd result space before returning
6161 * utils.c (query): Handle C-d to mean "yes", just as if the
6162 input was not a terminal. Also avoid infinite loop if EOF
6163 occurs in mid-input-line before newline. This allows
6164 query to be used at EOF on stdin with reasonable results.
6166 * infrun.c (proceed): Set breakpoint_proceeded.
6168 * values.c (value_as_long): Avoid infinite recursion for enums.
6169 (_initialize_values): Fix typo in help msg (kingdon).
6171 * Makefile.dist (RL_LIB): Use RL_LIB_DEP for dependencies,
6172 RL_LIB for linking. This allows -lreadline for linking
6173 and nothing for dependencies, once readline is a real library.
6175 * config.gdb: Jim Kingdon: give useful error message if the
6176 host or target type is not recognized.
6178 * defs.h (alloca): SPARC <alloca.h> does not declare alloca,
6179 it just defines it. Dumb, but deal with it.
6181 * Jim Kingdon suggests:
6182 in xconfig/sun3os4, CFLAGS should be XM_CFLAGS.
6184 Wed Aug 29 18:03:27 1990 John Gilmore (gnu at cygint)
6186 * Makefile.dist (VERSION): Bump version # to 3.91.2.
6188 * Clean up Bothner's changes.
6190 * blockframe.c (clear_pc_function_cache): New function.
6191 * blockframe.c: remake cache_pc_function_* static.
6192 * dbxread.c (symbol_file_command): remove references to
6193 cache_pc_function_* variables.
6194 * dbxread.c (read_struct_type): Use VOFFSET_STATIC.
6195 * printcmd.c: Avoid kludging a global variable (addressprint)
6196 to avoid printing the address of a string twice. Instead,
6197 pass the format letter 's' down low enough that it can be seen
6198 to avoid this problem.
6199 (print_formatted): Pass format arg to value_print.
6200 (restore_addressprint): Remove function.
6201 (do_examine): Avoid hacking addressprint, cleanups and such.
6202 (print_frame_args): Add a comment to a Bothner change.
6203 * symtab.h: define VOFFSET_STATIC and use it instead of "-1".
6204 * symmisc.c (free_all_symtabs): Call clear_pc_function_cache
6205 to wipe out the values cached in blockframe.c.
6206 * symtab.c (find_method): Add comment saying how big you must
6207 allocate to be "big enough". Per being terse again.
6208 * valprint.c (val_print): Handle format letter "s" to print
6209 strings without addresses. Add comment to vtbl printing code
6210 which casts with wild abandon. Rearrange reference-printing
6212 @0xaddr: value (print w/addressprint)
6213 value (print w/~addressprint)
6214 @0xaddr (parameter lists w/addressprint)
6215 or nothing (parameter lists w/o addressprint)
6217 Tue Aug 28 10:47:18 1990 John Gilmore (gnu at cygint)
6219 * Merge more changes from Per Bothner:
6221 Gdb's handling of TYPE_CODE_REF was so counter-C++ (and otherwise
6222 annoying) that I tried to improve it. Here are my suggestions.
6224 These patches all attempt to handle TYPE_CODE_REF (as in C++) better.
6227 Do automatic de-reference when taking the address of a reference.
6229 Don't deref_ref when printing parameter lists.
6231 More attempts at treating refernences properly.
6233 In val_print, if deref_ref==0, don't print dangling " = ".
6235 Add COERCE_REF macro, which de-references an REF.
6237 * Merge changes from Per Bothner:
6239 * Fixed (Sony news)-specific configuration problems.
6240 * Fixed other problems with using vanilla pcc and libc (enum problems;
6241 assumption that vsprintf exists).
6242 * Some major speed-ups (finc_pc_partial_function now caches a match;
6243 parsing avoids duplicate symbol_lookup calls).
6244 * Changed handling of baseclasses (no longer use baseclasses field
6245 of struct type, use the first n_baseclasses fields instead).
6246 * Various minor changes/fixes, most C++-related.
6249 Cache the most previous match from find_pc_partial_function.
6250 (Save both low and high ends of matching function's pc range.)
6251 This speeds up the loop of infrun.c:wait_for_inferior quite
6252 a bit, and makes step/next commands much zippier.
6254 Added an enum->int cast (otherwise, some compilers barf).
6256 No longer set baseclass offset to 0, since multiple
6257 inheritance now mostly works.
6258 Added a number of casts, to shut up compiler warnings
6259 (after stabs where made enums, not ints).
6260 When discarding a symbol table (in symbol_file_command),
6261 must clear the cache introduced in blockframe.c.
6262 Don't convert $vtbl_ptr_type to vtbl any more.
6263 Get rid of TYPE_BASECLASEES and baseclass_vec (see also symtab.h).
6264 Mask off sign bit emitted by g++ for virtual table offset.
6265 Set voffset to -1 (not 1) for static member functions.
6267 Changed parsing/lexing of names to avoid doing symbol lookup twice
6268 (once when lexing to determine symbol class, once for real).
6269 Now only call symbol_lookup once. Fields of 'this' win especially big.
6271 Subpress printing addr twice in the case of 'x/s addr'.
6273 lookup_basetype_type is no longer used.
6274 Add find_methods as recursive helper function to decode_line_1.
6275 This allows multiple inheritance to work.
6276 Also, once one or more matches has been found, do not look in
6277 base-classes. (Baseclass methods would be overridden, anyway.)
6279 Removed baseclasses array in struct type.
6280 Instead of using baseclasses[i], use fields[i-1].
6281 Added virtual_field_bits[i] to indicate if the i'th baseclass is virtual.
6282 Changed sign convention of voffset (previous was inconsistent).
6284 Some macros (CALL_DUMMY and relatives) were missing. Put them back.
6286 Used to assume existence of vsprintf. Re-written to not need it
6287 if HAVE_VPRINTF is undefined.
6289 typecmp was too pessimistic. Made it less so.
6291 Don't print space after address.
6292 If vtable points to a misc symbol (with 0 offset), print it,
6293 since that indicates the actual class of the object.
6294 Changed ype_print_derivation_info to use new inheritance
6295 scheme (without baseclasses vector).
6297 In value_primitive_field, fixed some bugs left over from previous set of fixes.
6298 Also, changes needed because TYPE_BASECLASSES were removed.
6300 REGISTER_U_ADDR didn't work for PC. Rewrote to use an array.
6302 Tue Aug 21 20:08:54 1990 John Gilmore (gnu at cygint)
6305 If there is no path set, and the symbols don't indicate what directory
6306 a file was compiled in, look in the current directory. But either
6307 a path or a known compilation directory will prevent this.
6310 Three independent bug fixes:
6311 * Remove the #if 0 block that breaks some stuff.
6312 * SunOS 4.1 fixed the promoted-parameter-wrong-addr bug in Sun C;
6313 adapt gdb to either SunOS 4.0.* or 4.1.
6314 * MAX_OF_TYPE and MIN_OF_TYPE thinko. By tedg@sun, I think.
6317 Instantiate the class T when looking for methods in it. (Tiemann@sun)
6320 (type_print) Demangle the name being printed.
6321 (type_print_base) Handle botched demangling without coredump (tiemann).
6324 (check_stub_method): Document routine.
6325 (tiemann) fix bug for no-arg functions
6326 Avoid clobbering beyond end of malloc'd storage.
6327 Terminate the argument list properly.
6329 Sat Aug 18 01:29:59 1990 Per Bothner (bothner@cs.wisc.edu)
6331 * Changes merged by John Gilmore:
6334 In breakpoint_1, use new print_address_symbolic instead
6335 of find_pc_partial_function. (This forces use of assembler-level
6336 addresses, and avoids misleading non-mangled source-level names.)
6338 Generalize ansi argument such that -1 means skip arglist totally.
6339 Removed global variable print_ansi_qualifiers (which made
6340 code non-reentrant), in favor of extra explicit arguments
6341 to internal routines.
6343 Add new helper function print_address_symbolic.
6344 Use find_pc_misc_function instead of find_pc_partial_function
6345 (since we want assembler-level symbols here).
6347 Print unknown function as just "f (...)", not "f (...) (...)".
6348 Use new fputs_demangled explicitly.
6350 Fixed a typing violation (problem: value.h cannot be imported
6351 without renaming many variable in this file).
6352 lookup_symbol: If no matching misc_func, look for a C++-mangled name.
6353 decode_line_1: Moved forward some never-reached code.
6354 Made decode_line_2 skip function prologues correctly.
6356 fputs_filtered should not demangle by default.
6357 Add new fputs_demangled to demangle on demand..
6359 Change value_struct_elt to use value_primitive_field (using recursive
6360 utility function search_struct_field). This allows foo.bar to work
6361 for multiple inheritance (so far only for data fields).
6362 Change check_field in the same way (recursive helper function
6363 to support multiple inheritance).
6364 (Note: there are more of these problems that I haven't fixed.
6365 Any code that says TYPE_BASECLASS (t, 1) is probably wrong.)
6366 value_of_this: 'this' symbol name is now just "this", note "$this".
6368 Don't print static members.
6369 Avoid printing "members of <type>" if there are none.
6370 Simplified type_print_derivation_info by merging duplicate code.
6371 Remove useless blank lines in type_print_base (ptype command).
6373 Added declaration of new routine value_primitive_field.
6375 Added value_primitive_field which is generalized version of
6376 value_field that can handle multiple inheritance (non-zero offsets etc).
6377 Re-implemented value_field to call value_primitive_field.
6379 Fri Aug 17 23:33:44 1990 John Gilmore (gnu at cygint)
6381 * infcmd.c -- insert else to avoid 'delete env' coredump when you
6382 delete the whole environment. Karl Berry reported the bug.
6383 * source.c - fix openp to avoid //'s in filenames, which
6384 trigger an Emacs bug causing it to not be able to find files
6385 when running gdb in a window.
6386 * dbxread.c - zap the #if 0 that botches the add-file code.
6387 It seems to work a lot better without all the code commented out.

6396 * Makefile - added a ${CFLAGS} to a couple of entries,
6397 added remote-sa.sparc.c
6398 * added remote.sa-sparc.c, a modification of remote.c
6399 which conducts a dialog directly with the SparcStation prom.

6401 remote_insert_breakpoint(), and remote_remove_breakpoint()
6402 to breakpoint.c instead of directly writing breakpoint instructions.
