5 Thu Dec 5 03:34:21 1991 John Gilmore (gnu at cygnus.com)
7 * coredep.c (fetch_core_registers): Fencepost error. Fixed by
8 Jay Lepreau <lepreau@cs.utah.edu>.
10 * inflow.c: Remember whether GDB has a terminal. Avoid switching
11 terminals back and forth if we don't have one.

14 * dbxread.c (read_dbx_symtab): Enum type numbers can be in (1,2) form.
17 * buildsym.c (define_symbol, read_range_type): Add
18 long_kludge_name that passes the names of range types being
19 defined, down to where we must choose between 'int' and 'long'
20 variants. This fails on Sun C anyway since the compiler itself is
21 confused between int and long.
22 (read_array_type, cleanup_undefined_types): Correct the size of
23 array type whose element-type size isn't immediately known.
25 Early preparation to blow away many builtin types, building them
26 on the fly as needed. Don't compare types to builtin types with
27 ==; examine the relevant fields instead.
28 * coffread.c (process_coff_symbol: C_ARG, C_REGPARM): Avoid ==.
29 * buildsym.c (define_symbol, case 'p'): Avoid ==.
30 * valops.c (value_arg_coerce): Avoid ==. Don't assume host and
31 target types are the same.
32 * valprint.c (val_print): I finally understand arrays, remove FIXME.
34 * symmisc.c (printpsyms_command): Reduce redundancy, and put all
35 addresses in GDB itself into parens for easy cleanup and diffing.
37 Wed Dec 4 21:05:30 1991 Fred Fish (fnf at cygnus.com)
39 * dwarfread (enum_type): Arrange for the order of enumeration
40 members to match the source code order; not the order in the
41 Dwarf information, which is explicitly reverse order.
43 Wed Dec 4 18:24:39 1991 John Gilmore (gnu at cygnus.com)
45 * main.c (input_from_terminal_p): Check whether GDB has a
47 (initialize_main): Revise doc for `set editing'.

63 * main.c (initialize_main): Revise command descriptions.
64 * command.c (show_user): `info user' -> `show user'.
65 * symtab.c (_initialize_symtab): Typo in `info types' desc.
67 * coffread.c (coff_symfile_read): Avoid select_source_symtab,
68 since it is not needed and can cause errors when examining ".o"s.
69 (read_coff_symtab, decode_base_type): Use complain, not printf.
70 Print symbol name, not its number.
71 Remove "#if defined(clipper) #define BELIEVE_PCC_PROMOTION", which
72 someday should go in a clipper target config file.
74 * symfile.c (compact_misc_function_vector): Handle empty vector.
75 (complain, clear_complaints, syms_from_objfile): Fix complaint
77 * xcoffexec.c: Change syms_from_objfile caller.
79 * sparc-xdep.c: Force tm-file as tm-sparc.h, to make it compile
80 when configured for cross debugging. FIXME, this needs a more
83 Mon Dec 2 11:04:05 1991 Per Bothner (bothner at cygnus.com)
85 * mips-tdep.c (init_extra_frame_info): Float register
86 'i' has gdb-internal number 'FP0+i', not '32+i'.
87 * mipsread.c (new_symbol): Translate g++ special
88 symbol "$t" to "this".
90 Sat Nov 30 21:29:55 1991 Steve Chamberlain (sac at cygnus.com)

114 * tm-i386v.h: Allow START_INFERIOR_TRAPS_EXPECTED and
115 DECR_PC_AFTER_BREAK to be predefined by files including
118 * i386-tdep.c: Add supply_gregset(), fill_gregset(),
119 supply_fpregset(), and fill_fpregset() functions, which are
120 target dependent support functions for the SVR4 /proc register
123 * dwarfread.c (enum_type, struct_type): Expand recognized
124 compiler generated tags to include symbols beginning with '.' as
127 * symtab.c (sources_info): Change simple printf of error message

138 Fix bugs in C++ debugging.
140 * symtab.h: target_type is not used in record types.
141 Eliminate TYPE_MAIN_VARIANT and TYPE_NEXT_VARIANT. Eliminate
142 lookup_method_type. Add TYPE_TYPE_SPECIFIC macro.

145 allocate one in symbol_obstack when we need one.
146 (allocate_stub_method): Build stub in symbol_obstack.
147 (check_stub_method): Move here from values.c. Don't deallocate
149 (lookup_method_type): Gone now.
151 * buildsym.c: Handle g++ v1 stabs a little bit better.
152 Change some C++ parsing error()s to complain()ts.
153 * buildsym.c, findvar.c, printcmd.c, symtab.c: Make unions and
154 structs have the same representation and work the same as far as
156 * buildsym.c, symtab.c, values.c: Remove all references to
157 TYPE_MAIN_VARIANT and TYPE_NEXT_VARIANT.
159 * valops.c: Improve comments and indentation. Only call
160 check_stub_method when the stub flag is on.
161 * valprint.c: Fix or mark minor bugs and unportabilities.
163 * coffread.c (anonymous unions): Allocate a cplus structure.
165 * mipsread.c: Eliminate "template" types. Build new, real
166 types whenever we need them. Allocate cplus structures as needed.
167 Bulletproof the type parsing a bit more. Mark storage leaks.
168 (parse_type): Copy TYPE_TYPE_SPECIFIC when copying a real type
169 on top of a partial type.
171 Fri Nov 22 16:39:57 1991 John Gilmore (gnu at cygnus.com)
173 * inflow.c (terminal_inferior): Check the results of ioctl's, and
174 print a message if any of them fail.
175 (terminal_ours_1): Store result of ioctl's for debugging, but
176 don't print (the terminal isn't ours...).
178 * tm-tahoe.h (FRAME_ARGS_ADDRESS): No need to offset from frame
181 * m2-exp.y (MAX, MIN): Rename to MAX_FUNC, MIN_FUNC to avoid
182 conflicts with system header files.
184 Fri Nov 22 08:27:40 1991 John Gilmore (gnu at cygnus.com)
186 * Roll VERSION to 4.2.95.
188 * buildsym.c, coredep.c, mem-break.c, xcoffread.c: Put <stdio.h>
189 first, before defs.h.
190 * config/mh-i386sco: Override compiler to gcc, print warning.
191 * configure.in: Handle i386-none-aout rather than i386-aout-none.
192 * infptrace.c, language.h, utils.c: Lint.
193 * m2-exp.y: #undef MAX and MIN in case system includes set them.
194 * xm-tahoe.h: Set HOST_BYTE_ORDER. Include system versions of
195 {BIG,LITTLE}_ENDIAN and the INT_MAX family first, to avoid
196 redefinition warnings.
197 * defs.h: Reorder things so that the xm-file gets first crack
198 at #define's, followed by defs.h and then the tm-file.
199 * Makefile.in: Remove spaces after 'ignore exit code' - flags.
200 Late-model BSD 'make's don't cope with them.
202 Thu Nov 21 23:48:56 1991 John Gilmore (gnu at cygnus.com)
204 * Makefile.in: Roll new files into various lists.
206 Thu Nov 21 18:26:11 1991 Fred Fish (fnf at cygnus.com)
208 * dwarfread.c (struct_type): Must initialize the c++ specific
209 portion of union types as well as struct types, since gdb attempts
210 to reference the c++ specific info for both types.
212 Thu Nov 21 10:23:52 1991 John Gilmore (gnu at cygnus.com)
214 * Makefile.in: Roll VERSION to 4.2.90.

236 Wed Nov 20 18:35:56 1991 John Gilmore (gnu at cygnus.com)
238 * Remove gdb/hp-include. Support for HP a.out oddities should be
239 in BFD, not in GDB. Move gdb/hp-include/a.out.h to include/a.out.hp.h.
241 * infptrace.c, tm-sun386.h: Cashier <a.out.gnu.h>, remove refs.
243 * configure.in, xconfig, tconfig, Makefile.in, doc/gdbint.texinfo:
244 Makefile fragments for various hosts and targets now come from
245 gdb/config/mh-* and gdb/config/mt-*. This is for consistency with
248 * rs6000-pinsn.c, rs6k-opcode.h: Clean up.
249 * rs6k-opcode.def: Delete.
251 Wed Nov 20 05:04:40 1991 Fred Fish (fnf at cygnus.com)
253 * dwarfread.c: Recognize obsolete form of AT_element_list
254 attribute still used by at least one AT&T compiler, and possibly
257 Tue Nov 19 07:53:55 1991 Fred Fish (fnf at cygnus.com)
259 * dwarfread.c (enum_type, struct_type): Ignore names invented by
260 helpful compilers for anonymous structs, unions, and enums.
262 * c-exp.y, m2-exp.y: Add defines for yymaxdepth, yy_yys, and
263 yy_yyv, so multiple parsers produced by SVR4 versions of yacc
264 can coexist in the same executable without collision.
266 * symtab.h: Add declaration for lookup_template_type() to kill
267 compiler warnings about conversions from int to pointer.
269 Mon Nov 18 17:45:18 1991 Fred Fish (fnf at cygnus.com)
271 * procfs.c: Move inclusion of defs.h to before param.h, as in
272 all the other source files that include both. This is required
273 to supply some typedefs that are used in files included by param.h.
275 * m68k-tdep.c (m68k_skip_prologue): Add generic m68k support for
276 skipping function prologues, ala the other cpu families (i386,
277 mips, m88k, etc). Add the ability to skip movm and fmovm
278 instructions in the prologues. Still needs support for profile
279 (-p compiled) prologue sequences (FIXME).
281 * tm-68k.h: Change SKIP_PROLOGUE macro to use the new generic
282 m68k prologue skipping function by default.
284 * tm-altos.h, tm-isi.h: Continue to use the old definition of
287 Mon Nov 18 15:12:45 1991 John Gilmore (gnu at cygnus.com)
289 * Makefile.in: Remove tdesc stuff, and extra blanks before colons.
290 * blockframe.c: Remove tdesc-related code. Default
292 * infrun.c: Remove tdesc-related code.
293 * m88k-tdep.c (frame_chain_combine, init_frame_pc): Remove copies
294 of defaultable things.
295 * tm-m88k.h: New file, common to all Moto 88k target configs.
296 Derived from tm-delta88.h.
297 * tm-delta88.h: Use it.
298 * xm-m88k.h: Common file for 88K hosts. Remove obsolete stuff.
299 * xm-delta88.h: Use it.
300 * tm-*.h: Remove FRAME_CHAIN_COMBINE macros, since all are
302 * coffread.c: Remove tdesc stuff.
303 * tconfig/delta88, tconfig/m88k: Remove tdesc stuff.
304 * xconfig/m88k: Rename tm-88k.h to tm-m88k.h.
306 Mon Nov 18 13:51:37 1991 Per Bothner (bothner at cygnus.com)
308 * source.c (open_source_file): If openp fails, try again
309 using just the base (non-directory) part of the filename.
310 This solves various annoying problems, such as when the
311 source was compiled with an absolute pathname - and the
312 source files have moved. Or if the source was compiled
313 using a relative pathname, it can be more convenient
314 to just specific the source directory to the dir command.
316 Mon Nov 18 00:04:41 1991 Fred Fish (fnf at cygnus.com)
318 * cplus-dem.c (munge_function_name): Add missing third arg to
319 instance of call to do_type().

325 Sun Nov 17 16:20:53 1991 Michael Tiemann (tiemann at rtl.cygnus.com)
327 * symtab.h (struct type): Moved C++-specific fields into new type
328 `struct cplus_struct_type'. Now takes 10% less memory. Many
330 * symtab.c (init_type): Don't set fields belonging to
331 TYPE_CPLUS_SPECIFIC unless TYPE is TYPE_CODE_STRUCT.
332 * buildsym.c (read_type): Allocate TYPE_CPLUS_SPECIFIC for
334 (read_struct_type): Ditto. Also, add comments about how we can
335 deduce TYPE_VPTR_FIELDNO from inheritance info and fieldname info.
336 * coffread.c (decode_base_type): Allocate TYPE_CPLUS_SPECIFIC for
338 (read_struct_type): Ditto.
339 * dwarfread.c (struct_type): Ditto.
341 * symtab.c (read_range_type): Don't set TYPE_MAIN_VARIANT.
342 (lookup_pointer_type): Don't use or set TYPE_MAIN_VARIANT.

352 * mipsread.c (parse_partial_symbols): patch to keep DEC C
353 compiler from making gdb bomb out. Thanks to Ed Santiago!
355 Thu Nov 14 19:27:30 1991 Fred Fish (fnf at cygnus.com)
357 * symfile.c: Add function compact_misc_function_vector() to
358 remove duplicate misc function vector entries. See comments
359 in source for why this is necessary/desirable.
361 * dwarfread.c: Add misc function type parameter to internal
362 record_misc_function(). Remove calls to init_misc_bunches()
363 and condense_misc_bunches(), these are now done in elfread.c.
365 * elfread.c: Add support for reading bfd canonical symbol tables
366 and generating misc function vector entries for global and
367 absolute symbols. Do calls to init_misc_bunches() and
368 condense_misc_bunches() where they will enclose all calls to
369 record_misc_function(), including those in dwarfread.c.
371 Thu Nov 14 17:02:11 1991 Roland H. Pesch (pesch at cygnus.com)
373 * doc/Makefile.in: new targets gdb.me, gdb.ms, gdb.mm
374 (roffable documentation).
375 * doc/gdb.texinfo: embedded hints (as comments) for better
376 texi2roff conversion.

392 Motorola 88000 port without tears, I mean without tdescs.
394 * m88k-tdep.c: Blow away all tdesc stuff.
395 Provide functions for all the frame-related macros in
396 tm-delta88.h. Adopt i960-style EXTRA_FRAME_INFO.
397 (examine_prologue, frame_find_saved_regs, skip_prologue): borrow
398 from i960-tdep.c and adapt to the function prologues on the 88k.
399 (read_next_frame_reg): Borrow from mips-tdep.c.
400 FIXME: frame_locals_address should go away.
402 * tm-delta88.h: Dump all the tdesc stuff.
403 Macros for all frame-related stuff call fns of same name.
404 Remove duplicated definitions. FP_REGNUM becomes same as
407 * xm-88k.h: Eliminate lots of library dependencies, now handled
408 in libiberty. Eliminate KDB nonsupport.
410 * doc/gdbint.texinfo: Add rudiments on frames. FIXME, add more.
413 * stack.c (frame_info): Mark frameless functions.
414 Print locals address (FIXME, remove if same).
415 * blockframe.c: Comment changes, FIXME after.
416 * coffread.c: Even without TDESC, need to zap "@" symbols.
417 Don't register for wierd format names; change the names in BFD.
419 * alloca.c, language.c, tdesc.c: Lint.
420 * tdesc.c, tdesc-lib: FIXME: remove these.
422 Tue Nov 12 19:30:22 1991 John Gilmore (gnu at cygnus.com)
424 * Makefile.in: Add tdesc library support. Fixups to lint,

431 Allow setting breakpoints on C++ destructors.
432 * valops.c (destructor_name_p): Don't check TYPE_HAS_DESTRUCTOR,
433 since it lies. Rely on callers to catch missing destructors.
434 * symtab.c (decode_line_1): For example (see above), here.
435 * buildsym.c, symtab.h: Remove TYPE_FLAGS_HAS{CON,DE}STRUCTOR
436 flags since they are no longer used.
438 Fixes to support C++ methods with functional parameters.
439 * c-exp.y (func_mod rule): Allow (and ignore) list of parameter
440 types in a function type.
441 * eval.c (parse_and_eval_type), value.h: New function,
442 parse_and_eval_type, is based on old code from check_stub_method.
443 But don't actually evaluate the cast, since that calls
444 value_cast(), whcih may fail. Just extract the type
445 from the parsed expression.
446 * values.c (check_stub_method): While looping through the
447 arguments, adjust depth *after* parameter has been handled.
448 Replace call and setup of parse_and_eval with new function

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

487 * dwarfread.c (dwarf_psymtab_to_symtab): Remove leftover call
488 to do_cleanups() which resulted from a previous change.
490 * elfread.c: Re-enable compilation of register_addr() stub
491 whenever it is not supplied by coredep.c
493 Sat Nov 9 00:40:32 1991 John Gilmore (gnu at cygnus.com)
495 Add tracking of object files (that contain symbols) to gdb.
496 This includes a "struct objfile" that owns symtabs and psymtabs
497 that were read in from that binary file.
499 * symfile.h: Add struct objfile. Add pointer to the objfile
500 into the struct sym_fns.
501 Replace global `symfile' and `symfile_mtime' with
502 `symfile_objfile'. Add global object_files chain.
504 * symfile.c: Move param.h above symtab.h.
505 (sort_misc_function_vector): Add.
506 (syms_from_objfile): Was syms_from_bfd.

514 (free_all_psymtabs, free_all_symtabs): Move here from symmisc.c.
516 * dbxread.c: Make more errors into complaints.
517 (push_subfile, pop_subfile): Move to buildsym.c.
518 (dbx_symfile_read, dbx_symfile_init, fill_symbuf, read_dbx_symtab,
519 start_psymtab, psymtab_to_symtab_1, read_ofile_symtab,
520 dbx_psymtab_to_symtab, ): Use bfd ops, don't use file descriptor.
521 Pass objfile. Change callers.
522 (fill_symbuf, SWAP_SYMBOL): Take bfd as arg.
523 (read_dbx_symtab): Just wipe out new symbols, not all, on error.
524 (end_psymtab): Blow away psymtab if empty.
525 (process_symbol_pair): Swallow into read_ofile_symtab.
526 (process_one_symbol): Use push_context and pop_context.
527 (virtual_context): Delete #if 0'd obsolete stuff.
529 * buildsym.c (end_symtab): Pass objfile.
530 (dbx_lookup_type): Handle null typevector.
531 (dbx_alloc_type): Check file number, not sym number, for -1.
532 (find_symbol_in_list): Add for xcoffread.
533 (start_symtab): Default typevector is empty. Keep reusing same
535 (end_symtab): Take objfile argument and pass it to
536 allocate_symtab. Don't make a symtab if no blocks or symbols.
537 Handle empty typevector.
538 (push_context): New function for context stack nesting.
539 (read_type): Mark FIXME where we need to reintroduce type smashing.
541 * buildsym.h (pop_context): Macro, paired with push_context.
542 (subfile_stack): Move here from dbxread.c.
544 * coffread.c (end_symtab, read_coff_symtab): Take and use objfile arg.
545 (read_coff_symtab): Cleanup by freeing objfile, not all symtabs.
547 * mipsread.c (read_mips_symtab, parse_partial_symbols, parse_fdr,
548 new_psymtab, new_symtab): Take and use objfile arg.
550 * dwarfread.c (scan_compilation_units, start_psymtab,
551 process_dies, end_symtab, dwarf_build_psymtabs,
552 read_lexical_block_scope, read_func_scope, read_file_scope): Take
553 and use objfile argument.
554 (psymtab_to_symtab_1, read_ofile_symtab): Don't take or use file
555 descriptor. Use BFD internal functions instead.
556 (end_symtab): Call global allocate_symtab.
558 * elfread.c, target.c: Minor changes to accommodate objfiles.
559 * symtab.h: partial_symbol_table has no symfile_name member now.
560 (fn_fieldlists voffset): avoid non-int bitfield.
561 (struct symtab): Add objfile * and objfile_chain * of symtabs.
562 (struct partial_symtab): Add objfile * and objfile_chain * of
563 psymtabs. Remove symfile_name.
565 * symmisc.c: Lose free_all_symtabs, free_all_psymtabs.
566 (printsyms_command): Rename from print_symtabs. Add selective
567 listing if 2nd argument given. Print objfile info.
568 (printpsyms_command): Rename from print_partial_symtabs. Ditto all.
569 (printobjfiles_command): New; prints objfiles lists, and checks

572 * symfile.h, symfile.c, symtab.h: Lint
574 Fri Nov 8 23:38:48 1991 John Gilmore (gnu at cygnus.com)
576 * command.c: Include param.h.
577 * defs.h (warning_setup, warning): Declare.
578 * expprint.c (print_subexp, UNOP_MEMVAL case): Lint.
579 * inflow.c (new_tty): Use USE_O_NOCTTY #define.
580 * language.c, printcmd.c (print_scalar_formatted), signame.c,
583 Thu Nov 7 18:26:15 1991 Steve Chamberlain (sac at rtl.cygnus.com)
585 * Makefile.in: link with libiberty after libreadline, since
586 readline might want something in libiberty.
587 * m88k-xdep.c: Fixed the register offsets in the ptrace_user
588 struct for BCS 88k machines.
589 * xm-m88k.h: don't define USIZE if already defined.
590 * configure.in: Added delta88 target.
592 Thu Nov 7 04:51:19 1991 John Gilmore (gnu at cygnus.com)
594 * am29k-pinsn.c, am29k-opcode.h: Fix decoding of mtacc, dmac, fmac.
596 * tm-*.h: Remove READ_DBX_FORMAT, COFF_FORMAT, and
597 READ_MIPS_FORMAT, which have been unused since BFD. Still
598 remaining is COFF_NO_LONG_FILE_NAMES.
599 * tm-sun3.h, tm-altos.h: Remove detritus accidentally left from
600 function calling code moved to m68k-tdep.c.
602 Wed Nov 6 17:21:59 1991 John Gilmore (gnu at cygnus.com)
604 * coffread.c: Eliminate c_nsyms in favor of c_naux.
605 Complain if no auxents on .bf and .ef FCN symbols, and assume
606 lots of line numbers.
607 (init_linenos, enter_linenos): Use a sentinel at the end of the
608 read-in linenos, to make for a fast, safe loop-end test.
610 Wed Nov 6 02:54:08 1991 Steve Chamberlain (sac at cygnus.com)
612 * coffread.c (read_coff_symtab): coffread used to rely on the
613 x_sym.x_misc.x_lnsz.x_lnno field giving the # of linnos in a
614 function. Two of the formats I'm using (29k and 88k) don't seem to
615 set it. Ths patch to fcn_last_line and (enter_linenos) is an
616 attempt to use the actual size of the linno table in the file to set
617 the number of linenos to process.
619 Tue Nov 5 22:47:46 1991 Steve Chamberlain (sac at cygnus.com)
621 * Makefile.in: put a - infront of the mv y.tab.c c-exp.tab.c and
622 mv y.tab.c m2-exp.tab.c, so that if bison is used, and the files
623 are created in place, so the mv fails, then the make continues.
625 Tue Nov 5 16:47:47 1991 Per Bothner (bothner at cygnus.com)
627 Add C++ as a separate language.
628 * defs.h (enum language): Add language_cplus.
629 * dwarfread.c (end_symtab): Support language_cplus.
630 * c-exp.y: Add new struct language_defn cplus_language_defn.
631 Don't set c to be the default language (see main.c).
632 * c-exp.y (yylex): Only look for field of this if
633 language is C++. (First difference from C!)
634 * language.c: Add case branches for C++ (currently, all
635 the same as C). Also, add c++ to "usage" note for "set lang".
636 * valprint.c (typedef_print). Add case branches for C++.
637 * main.c (main): New way to set initial language: Look at
638 file extension of psymtab containing main(). (Same as we
639 do for symtabs, but avoid loading the symtab yet.)
640 * symtab.c: New routine find_main_psymtab(), used by main()
641 to set initial language.
642 * symfile.c (allocate_symtab): Move code for mapping file
643 extensions-> languages to new deduce_language_from_filename().
645 Fix a C++ problem when looking for methods in super-classes.
646 There was confusion between base and derived types.
647 * valops.c (value_fn_field): Change function interface.
648 * values.c: Use new value_fn_field interface.
650 Mon Nov 4 10:49:33 1991 Per Bothner (bothner at cygnus.com)
652 * infrun.c: Fixed typo in comment.
653 * utils.c: All the v*fprintf emulation is now in libiberty,
654 so we can get rid of some junk.
655 * xm-sun3os4.h, xm-sun4os4.h, xconfig/decstation, xconfig/i386sco,
656 xconfig/sun3os4, xconfig/sun4os4: Don`t need HAVE_STRSTR any more.
657 * m68k-pinsn.c (print_insn_arg): Support BB/BW/BL
658 type operands, as used by branch instructions.
659 * gmalloc.c: Fix prototype of memcpy.
660 * elfread.c: Comment out register_addr, since it conflicts
661 with the one in coredep.c.
662 * buildsym.h: Remove extern declarations of two functions
663 that are really static in buildsym.c.
664 * tm-mips.h: Add symbolic names for more registers.
665 * mips-xdep.c (store_inferior_registers): Use new register names.
666 * xm-mips.h: Simplify REGISTER_U_ADDR, since it is now
667 only used for core files, not ptrace. Therefore,
668 the KERNEL_U_ADDR hack is no longer needed.
669 The mapping to ptrace number is now in in mips-xdep.c.
670 * mips-xdep.c: Define REGISTER_PTRACE_ADDR (using the
671 mapping from the old REGISTER_U_ADDR), and use it
672 in {fetch,store}_inferior_registers.
673 * mipsread.c: Rename #include ecoff.h to new name coff-mips.h.
674 * mips-tdep.c (mips_push_dummy_frame, mips_pop_frame):
675 Save/restore FP regs correctly (?).
676 * dbxread.c: Remove duplicate define_symbol and type_synonym_name
677 (these had been previously moved to buildsym.c).
678 Hence, define_symbol becomes extern instead of static.
679 * buildsym.c (read_struct_type): Comment out bogus handling
680 of C++ operator methods. Minor hacking of reading of class
681 contexts. Make define_symbol non-static, so dbxread.c can call it.
683 Fri Nov 1 11:05:47 1991 John Gilmore (gnu at cygnus.com)
685 * mipsread.c (read_mips_symtab, read_the_mips_symtab): Use real
686 filename with error messages.
687 * stack.c (frame_select_command): Rename to select_frame_command
688 to avoid "fr" and "fra" having nonunique completions.
689 * symfile.c (sort_symtab_syms): Ignore sort of zero symtab *.
690 (symfile_init): Print file format name when unable to handle it.
691 (free_named_symtabs): Use BLOCKVECTOR rather than obsolete BLOCKLIST.
692 * symmisc.c (free_symtab): Only free linetable if nonzero.
693 * symtab.h: Remove obsolete BLOCKLIST macros.
695 Thu Oct 31 18:12:43 1991 Stu Grossman (grossman at cygnus.com)
697 * infrun.c (wait_for_inferior): another stepi/nexti fix. Ensure
698 that stop_step is 1 at bottom of main loop. I don't know why this
699 needs to be done, but it helps me sleep better at night.
701 Sun Oct 27 18:18:39 1991 Stu Grossman (grossman at cygnus.com)
703 * main.c (initialize_history): Read history after reading all
706 Sun Oct 27 14:09:25 1991 John Gilmore (gnu at cygnus.com)
708 * buildsym.c: Break out initial malloc sizes.
709 (record_line): Record directly in a subfile. Alloc on demand.
710 (compare_line_numbers): Add from xcoffread.c.
711 (end_symtab): New params say whether to sort pendings and
712 linetable. Patch block stabs if defined. Shrink linetable before
713 allocating the symtab.
714 * buildsym.h: Delete line_vector* and prev_line_number. Add
715 global_stabs and file_stabs for xcoffread.
716 * dbxread.c (start_subfile): Move to buildsym. Change above calls.
717 * symtab.h: LINETABLE(symtab) can now be null. Zap LINELIST.
718 * symmisc.c, symtab.c: Cope with null LINETABLEs.
720 * blockframe.c: Pass fromleaf to INIT_EXTRA_FRAME_INFO.
721 * tm-29k.h, tm-88k.h, tm-i960.h, tm-irix3.h, tm-mips.h, tm-pyr.h,
722 tm-sparc.h: Accept fromleaf parameter.
723 * c-exp.y (yyerror): Pass error message if given.
724 * configure.in: Add rs6000 host and target.
725 * inflow.c (new_tty): O_NOCTTY kludge for RS/6000.
726 * symfile.h (entry_point): Add.
728 Sat Oct 26 00:16:32 1991 John Gilmore (gnu at cygus.com)
730 * buildsym.c: New file. Breaks out symbol-table-building routines
731 from dbxread.c, so they can be shared with xcoffread.c.
732 * buildsym.h: New file. Declarations for buildsym.c users.
733 * dbxread.c: Remove large chunks into buildsym.c.
734 * Makefile.in: Add buildsym.c and buildsym.h.
736 * symfile.c (syms_from_bfd): New routine.
737 (add_symbol_file): Call it to do the real work.
738 (syms_from_bfd): Initialize entry_point before calling symfile_init.
739 * symtab.h, symfile.c, coffread.c, mipsread.c, dwarfread.c:
740 Avoid declaring or setting entry_point (symfile.h & symfile.c cope).
742 Fri Oct 25 10:58:16 1991 Mark Eichin (eichin at cygnus.com)
744 * cplus-dem.c (cplus-demangle): added support for templates, static
745 data, and the new (correct) mangling for destructors.
747 * dwarfread.c: (dwarfwarn): created a varargs version of
748 dwarfwarn, for non __STDC__ compilers.
750 * c-exp.y: (yylex): added match for "template" token.
751 (typebase): added TEMPLATE name '<' type '>' clause, for explicit
752 specification of template types.
754 * symtab.c: (lookup_template_type): new function for finding
755 templates in symbol table.
756 (type_name_no_tag): changed to explicitly check for s/u/e at the
757 beginning of the symbol - if it is a template, none of these will
758 be there (but the name will still contain spaces.)
760 Fri Oct 25 18:59:32 1991 Per Bothner (bothner at cygnus.com)
762 Various fixes to improve g++ debugging.
763 * symtab.h: Add is_const and is_volatile flags for each method.
764 These are bit fields - take their space from voffset,
765 which shrinks to 30 bits. Since voffset is now a bitfield,
766 make it unsigned for portability. This changes its interpretation
767 slightly: Static methods now have voffset 1 instead of -1,
768 and virtual offsets start at 2, not 1.
769 * symtab.c: Renamed gdb_mangle_typename to gdb_mangle_name,
770 since it now returns an entire magled method name, not just
771 the type part. This avoids some duplication.
772 It also allows us to correctly mangle const and volatile
773 methods (using the new is_const and is_volatile bit fields
775 * valprint.c (type_print_base), values.c (check_stub_method):
776 Simplify by using new gdb_mangle_name.
777 * values.c (value_headof): Fix to correctly handle single
778 inheritance (actually two fixes, either of which suffices).
779 * dbxread.c (read_struct_type): Handle const and volatile
781 * dbxread.c (read_struct_type): Yet one more place where
782 we must handle '\\' continuations.
783 * valprint.c (vtbl_ptr_name): Add final '\0'.
785 Fri Oct 25 16:06:38 1991 Stu Grossman (grossman at cygnus.com)
787 * tm-sparc.h, tm-68k.h (EXTRACT_RETURN_VALUE): fix output of
788 short return values for sparc and 68k. Patch from Paul Eggert.
790 * coffread.c, coredep.c, i386-xdep.c: install patches for
791 SysV/386 3.2 from Mauro DePalma.
793 Fri Oct 25 02:02:13 1991 John Gilmore (gnu at cygnus.com)
795 * core.c (core_file_info), exec.c (exec_file_info): Print file
796 type. Use printf_filtered.
798 * valops.c (value_fetch_lazy): Avoid 0-length fetches.
800 Thu Oct 24 23:06:40 1991 Fred Fish (fnf at cygnus.com)
802 * dwarfread.c: Add casts to remove compiler warnings.
804 * tm-3b1.h, tm-68k.h, tm-altos.h, tm-amix.h, tm-hp300bsd.h,
805 tm-hp300hpux.h, tm-isi.h, tm-news.h, tm-pn.h, tm-sun2.h,
806 tm-sun3.h: Remove locally duplicated code for calling functions
807 in the inferior. The only differences were in the specific trap
808 vectors used and whether or not an fpu was present. These are
809 now handled by appropriate definitions of BPT_VECTOR and
810 HAVE_68881 respectively. Other minor obvious cleanups.
812 * valops.c: Correct a minor misspelling.
814 * utils.c: Remove local BSD/USG hacks that are now in libiberty.
816 * dwarfread.c: Remove prototype for dwarfwarn. Does not work
819 Thu Oct 24 09:33:44 1991 John Gilmore (gnu at cygnus.com)
821 * stack.c (frame_command): Always print. Use new
822 frame_select_command to select a frame without printing.
824 * dwarfread.c: Use <varargs.h>, since <stdarg.h> is not portable.
826 Thu Oct 24 01:32:51 1991 Fred Fish (fnf at cygnus.com)
828 * dwarfread.c: New file for DWARF debugging format support.
830 * elfread.c: New file for ELF object file format support.
832 * procfs.c: New file for SVR4 /proc (process file system) support.
834 * tm-amix.h, xm-amix.h, tconfig/amix, xconfig/amix: New files for
837 * xm-svr4.h, tm-svr4.h: New files for SVR4 support.
839 * xm-m68k.h: New file for host machines with m68k cpu.
841 * Makefile.in: Add elfread.c and dwarfread.c to SFILES_MAINDIR.
842 Add elfread.o and dwarfread.o to OBS.
844 * symfile.h: Add "elf" to list of supported formats in comment.
846 * c-exp.y, defs.h, symtab.h, valprint.c: Add three new builtin
847 types to gdb, builtin_type_long_double, builtin_type_complex, and
848 builtin_type_double_complex. Add and use new TARGET_SHORT_BIT,
849 TARGET_INT_BIT, TARGET_LONG_BIT, TARGET_FLOAT_BIT,
850 TARGET_DOUBLE_BIT, TARGET_LONG_DOUBLE_BIT, TARGET_COMPLEX_BIT, and
851 TARGET_DOUBLE_COMPLEX_BIT, as the sizes in bits of the indicated
852 types on the target machine (ala the existing TARGET_LONG_LONG_BIT).
854 * infrun.c: When using SVR4 /proc interface instead of ptrace(),
855 call proc_set_exec_trap() to setup child to stop at first instruction.
857 * inftarg.c: When using SVR4 /proc interface, call proc_wait()
860 * m68k-tdep.c: Add new routines supply_gregset(), fill_gregset(),
861 supply_fpregset(), and fill_fpregset(), which are machine
862 dependent support routines for SVR4 /proc interface.
864 * utils.c: Add warning_setup() and warning(). Warning() behaves
865 the same as error() except that it returns normally rather than
866 jumping back to command level. Modules that don't want to call
867 warning() for some reason, but want to produce their own warnings,
868 can call warning_setup() to ensure compatibility with the way
869 warning() and error() deal with the terminal.
871 * symtab.c: Make internal errors produce more useful messages.
873 * tm-68k.h: Move code that is duplicated in almost every single
874 m68k based machine's configuration files to this common file.
875 Duplications in the configuration files still need to be removed
878 * infrun.c (child_create_inferior): System V versions must call
879 setpgrp() with no arguments, to comply with prototyping typically
882 * munch: Add support for SVR4 style nm output.
884 * dbxread.c, mipsread.c symmisc.c, symtab.c: Remove the object
885 file specific fields from the partial symbol table structure and
886 replace them with a pointer to private data for each different
887 flavor of object file reader to initialize appropriately.
889 Wed Oct 23 09:38:20 1991 John Gilmore (gnu at cygnus.com)
891 * xconfig/sun[34]os4: Add note about strstr botch on sunos4.0.3c
894 * mipsread.c (fixup_undef_type): New function. If a struct /
895 union / enum is defined in a header file but nowhere else used,
896 (by typedefing, pointer referencing or declaration) the mipsread code
897 builds the complete tree for the structure but leaves its code as
898 TYPE_CODE_UNDEF as it doesn't know what kind of aggregate it is.
899 Guess its type based on the details of the members.
901 Tue Oct 22 18:04:32 1991 Stu Grossman (grossman at cygnus.com)
903 * infrun.c (wait_for_inferior): Check return value from
906 Mon Oct 21 17:47:03 1991 Stu Grossman (grossman at cygnus.com)
908 * infrun.c (wait_for_inferior): fix stepi/nexti that was broken
909 by my last edit to this routine.
911 Mon Oct 21 14:27:43 1991 John Gilmore (gnu at cygnus.com)
913 * tm-sun3.h (FIX_CALL_DUMMY): problem with cross debugging.
914 FIX_CALL_DUMMY does unaligned accesses and/or forgets to byte swap
915 the values before putting them into the dummy code. (From Peter
918 Mon Oct 21 10:04:39 1991 Steve Chamberlain (steve at rtl.cygnus.com)
920 * configure.in: added ebmon target.
922 Wed Oct 16 22:49:58 1991 John Gilmore (gnu at cygnus.com)
926 * Makefile.in: Roll VERSION to 4.2.
927 * README, TODO, WHATS.NEW: Update.
929 * core.c (core_open): Improve error message for bad file.
930 Pass .reg virtual memory address to fetch_core_registers to help
931 it find the registers in the core-file header.
932 * coredep.c (fetch_core_registers): Take new argument, use it,
933 and pass it to register_addr to locate the block of registers.
934 * xm-mips.h: Update KERNEL_U_ADDR for new scheme. Cleanup a bit.
936 * dbxread.c (read_dbx_symtab, process_one_symbol): Handle
937 Sequent N_FN_SEQ like everybody else's N_FN.
939 * main.c: Circumvent SCO cc bug with #if !!defined(USG).
940 * tm-i386v.h: #endif guck.
941 * xconfig/i386*: Remove -Dgetpagesize()=4096 kludge.
942 * xconfig/i386sco: Add HAVE_STRSTR to avoid ANSI bdeath.
943 * xconfig/tahoe: Add REGEX, which seems to be missing.
945 * coredep.c: Add <sys/types.h> for SCOnix.
946 * dbxread.c (read_dbx_symntab): Avoid coredump on malformed file.
947 * printcmd.c (print_formatted): Flush output before disassembly.
949 Tue Oct 15 20:12:32 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
951 * doc/refcard.tex (sec "Working Files"): consistent metavars and
952 other improvements, due to comments by François Pinard
953 (pinard@iro.umontreal.ca)
955 * doc/gdb.texinfo (appendix "Installing GDB"): changes in
956 configure, and improvenets related to Pinard's refcard comments
958 Tue Oct 15 08:45:12 1991 John Gilmore (gnu at cygnus.com)
960 Changes from Fred Fish:
961 * tm-68k.h (FPI_REGNUM): Add.

982 * doc/gdb.texinfo: Catch up to changes recorded here in ChangeLog
983 (nodes Continuing and Stepping; Memory; Targets) clarifications
986 Fri Oct 11 23:27:06 1991 John Gilmore (gnu at cygnus.com)
988 * tm-{irix3,mips,nindy960,pn,symmetry,vx960}.h: Move
989 REGISTER_U_ADDR to corresponding xm- file. Sugg. by Peter Schauer.
991 * symmisc.c (print_partial_symtabs): Add printpsyms debug cmd.
993 * m68k-tdep.c (m68k_push_dummy_frame, m68k_pop_frame): Add
994 generic routines for calling inferior functions.
996 * blockframe.c (inside_main_scope, inside_entry_scope): New.
998 * copying.awk: Filter formfeeds out of copying & warrantee.
999 Make them available as `show copying' and `show warrantee' also.
1000 * main.c (print_gnu_advertisement): Advt `show' commands.
1002 Thu Oct 10 17:25:47 1991 John Gilmore (gnu at cygnus.com)
1004 * mach386-xdep.c: Even when cross-compiling, leave in the
1005 core-file reading code.
1006 * core.c (get_core_registers): Avoid coredump if no .reg section.
1008 Wed Oct 9 17:03:34 1991 John Gilmore (gnu at cygnus.com)
1010 * mipsread.c, coffread.c: initialise TYPE_VPTR_FIELDNO to -1.
1011 This avoids coredumps under `set print object on' in value_headof
1012 (called erroneously by value_from_vtable_info) for `p &struct'
1013 or `p *struct'. From Peter Schauer.
1015 Mon Oct 7 00:06:52 1991 John Gilmore (gnu at cygnus.com)
1017 * Makefile.in: Roll version to 4.1.2.
1018 * dbxread.c: Use aout64.h, not a.out.gnu.h. Get external symbol entry
1019 size from BFD (but, FIXME, we don't yet read external nlists's and
1020 convert them to internal nlists's before handling them -- we still
1021 assume they have the same size and alignment.) Use SET_NAMESTRING
1023 * exec.c (exec_file_command): Move dead coff-encapsulation code
1025 * m88k-tdep.c, m88k-xdep.c: Remove encap test and #inc <a.out.h>.
1027 Fri Oct 4 22:30:06 1991 John Gilmore (gnu at cygnus.com)
1029 * configure.in, tm-i386v.h, xm-i386v.h: Intel 386 Mach host port.
1030 * xm-i386mach.h, mach386-xdep.c, xconfig/i386mach: New files.
1032 Fri Oct 4 17:04:31 1991 Per Bothner (bothner at cygnus.com)
1034 More patches from Peter Schauer <pes@regent.e-technik.tu-muenchen.de>:
1035 * mips-xdep.c (store_inferior_registers): Don't try to
1036 write the (pseudo) FP.
1037 * mipsread.c (parse_partial_symbols): Improved algorithm for
1038 setting pst->texthigh.
1040 Fri Oct 4 16:47:32 1991 Roland H. Pesch (pesch at cygnus.com)
1042 * doc/Makefile: make TEXINPUTS include . everywhere
1044 Fri Oct 4 00:35:56 1991 John Gilmore (gnu at cygnus.com)
1046 * coffread.c, dbxread.c, symfile.c, symmisc.c, symtab.h: Remove
1047 vestiges of typevectors, which were for symsegs and are no longer
1048 used. (From a question by Eliot Dresselhaus
1049 <dresselh@RFT30.nas.nasa.gov>).
1051 Thu Oct 3 09:33:26 1991 John Gilmore (gnu at cygnus.com)
1053 * dbxread.c, coffread.c: static-ize functions that were
1054 gratuitiously external. (From Fred Fish.)
1056 * c-exp.y: sym->class to SYMBOL_CLASS (sym).
1058 * dbxread.c (dbx_lookup_type): Keep doubling size of typevector
1059 until it is large enough.
1061 * dbxread.c (read_type): Handle error case slightly better.
1062 Make complaint message not C++-specific.
1064 Wed Oct 2 17:21:07 1991 Stu Grossman (grossman at cygnus.com)
1066 * infrun.c (wait_for_inferior): Fix step/next so that you only
1067 stop at the beginning of a new line. This fixes various problems
1068 with for loops, nested if-else's and switch statements.
1070 Tue Oct 1 06:33:55 1991 John Gilmore (gnu at cygnus.com)
1072 * symtab.c (lookup_symtab_1, lookup_symbol): "fatal" errors
1073 between symtabs and psymtabs become ordinary error()s.
1075 * dbxread.c (read_dbx_symtab): Relocate end_of_text_addr
1076 properly, making "end pc" correct in shared lib psymtabs.
1077 (From Guy Harris <guy@auspex.com>.)
1079 Mon Sep 30 13:15:31 1991 John Gilmore (gnu at cygnus.com)
1081 * dbxread.c: Enable, but soften, const_vol_complaint.
1082 (read_dbx_symtab): N_STSYM and N_LCSYM define static vars.
1083 Ditto Gould N_NBSTS and N_NBLCS. Also, all types in the psymtab
1084 should be file-scope, not global.
1085 (read_struct_type): Remove ancient multiple-inheritance warning.
1086 (read_range_type): Check base type, complain & patch if undefined.
1087 * stack.c (frame_info): Demangle the function name in `info stack'.
1088 (From Peter Schauer)
1090 Sat Sep 28 10:02:33 1991 John Gilmore (gnu at cygnus.com)
1092 * eval.c (evaluate_subexp_for_address): Don't use
1093 TYPE_POINTER_TYPE directly (it might be zero if this type has
1094 never had a pointer created before); use lookup_pointer_type.
1095 * symtab.c (lookup_method_type): Arguments were swapped in all
1096 callers, so fix it here. I'm amazed this worked at all!
1098 Fri Sep 27 18:09:31 1991 John Gilmore (gnu at cygnus.com)
1100 * c-exp.y, m2-exp.y: Define more yysymbols that happen to be
1101 "bss" rather than "data" symbols, but which still conflict.
1104 * coffread.c (coff_symfile_read): Use xmalloc, not malloc.
1105 * core.c (core_files_info): Shorten output.
1106 * exec.c (exec_files_info): Ditto.
1107 (build_section_table): Ignore zero-length sections.
1108 * language.c, printcmd.c: Lint.
1109 * language.h (get_frame_language): Declare.
1110 * saber.suppress: update.
1111 * stack.c (find_relative_frame): Remove complex code that was
1112 #if 0'd, stick with simple code. Lint.
1113 * saber.suppress: Update a bit.
1114 * symfile.c (add_symbol_file_command): Add "?" to question.
1115 * utils.c (parse_escape): Avoid \a due to bdead compilers.
1116 * value.h: Declare typedef_print.
1118 * valprint.c (val_print, type_print_base): TYPE_CODE_RANGE less
1121 * nindy-tdep.c (nindy_frame_chain_valid): Use lookup_misc_func.
1122 (Reported by Mark Peek <mark@imagen.com>.)
1124 * solib.c (solib_map_sections): Relocate all sections, even
1125 though only the text section's size is tracked. Mark ld_text
1126 for eventual elimination as we generalize to N sections.
1128 * infrun.c (wait_for_inferior): Don't check if the PC is in a
1129 call_dummy if we were stopped by a random signal that is being
1130 passed to the program. This produced wierd results when calling
1131 functions in the inferior and signals (e.g. SIGALRM) were in use.
1133 Tue Sep 24 18:05:30 1991 John Gilmore (gnu at cygnus.com)
1135 * infrun.c (IN_SIGTRAMP): Not parenthesized properly.
1136 Bugfix from Paul Eggert <eggert@twinsun.com>.
1137 * tm-ultra3.h (IN_SIGTRAMP): Ditto.
1138 * valprint.c (print_floating): Print 9 digits for IEEE floats.
1141 Mon Sep 23 15:50:07 1991 John Gilmore (gnu at cygnus.com)

1147 Fri Sep 20 16:10:52 1991 John Gilmore (gnu at cygnus.com)
1151 * Makefile.in (VERSION): Set to 4.1.
1152 * language.c (set_language_command): Print useful help message,
1153 and restore the language string after giving help.
1154 * valprint.c (typedef_print): Print typedef in C or M2.
1155 * symtab.c (list_symbols): Use it.
1156 * main.c (main): Avoid any output before (gdb) prompt when -q.
1157 * language.c (set_language_command): Handle errors by restoring
1158 the language string to its current state (fix from A. Beers).
1159 * doc/gdbint.texinfo: Roll in information from README. Rearrange
1160 "how to install" and "how to print the doc" stuff so it drops
1162 * configure.in: Rename rtpc CPU to romp to match config.sub.
1163 * README, WHATS.NEW, TODO: Update for gdb-4.1.
1165 Fri Sep 20 17:39:14 1991 Roland H. Pesch (pesch at cygnus.com)
1167 * doc/gdb.texinfo: Updates from ChangeLog. set/show write,
1168 autoloading shared libs, copyright etc on GDB startup, clean up $_
1169 and $__ index refs, set/show listsize and related updates to list
1170 cmd. New host/target configs.
1172 Fri Sep 20 15:46:00 1991 Roland H. Pesch (pesch at cygnus.com)
1174 * doc/Makefile: generate aux version-no file doc/gdbVN.m4
1175 from main Makefile.in version definition
1176 doc/gdb.texinfo: use version recorded in doc/gdbVN.m4 for current
1178 Makefile.in (setup-to-dist): generate doc/gdbVN.m4
1180 * doc/gdb.texinfo: merge new language-switching and lang-specific
1183 Fri Sep 20 15:00:57 1991 Per Bothner (bothner at cygnus.com)
1185 * mcheck.c: Add __ONEFILE kludge to allow compilation by non-ANSI
1186 compilers (which may lack stddef.h).
1188 Fri Sep 20 13:29:42 1991 John Gilmore (gnu at cygnus.com)
1190 * dbxread.c (read_dbx_symtab, process_one_symbol): N_FN and
1191 N_WARNING are the same except for the N_EXT bit, so just use their
1192 values alone, rather than OR-ing them with N_EXT.
1194 Fri Sep 20 12:27:55 1991 Stu Grossman (grossman at cygnus.com)
1196 * mipsread.c (parse_lines): Deal with negative extended line
1199 * c-exp.y, m2-exp.y: #define yyerrflag and yynerrs to avoid
1200 global symbol conflicts.
1202 Fri Sep 20 02:28:15 1991 John Gilmore (gnu at cygnus.com)
1204 * .gdbinit: Move 'set complaints' to top, so it runs even in
1205 case we aren't debugging GDB.
1206 * language.c (_initialize_language): Fix type check and range
1207 check documentation strings.
1208 * utils.c (!HAVE_VPRINTF): Define vfprintf as a function, so
1209 language.c can use it. (Though language.c should really not be
1210 handling warnings/errors the way it does, FIXME.)
1211 * symtab.c (lookup_primitive_type): const lint.
1213 Bugfix from Peter Schauer:
1214 * source.c (lines_to_list): Make signed, to avoid comparison
1215 going unsigned and complaining that -3 is too high for 21 lines.
1216 * stack.c (lines_to_list): Ditto.
1218 Thu Sep 19 23:33:41 1991 John Gilmore (gnu at cygnus.com)
1220 * Makefile.in (HFILES): Add minimon.h.
1221 (VERSION): Roll version number to 4.0.95.
1222 (gdb.tar.Z, make-proto-gdb.dir, setup-to-dist, gdb-XXX.tar.Z):
1223 New rules for building distributions. Normal distribution
1224 is built by doing `make -f Makefile.in gdb.tar.Z' in the directory
1225 one level up from here; it calls make-proto-gdb.dir to build a
1226 directory `proto-gdb' which is an image of the release. The old
1227 `gdb.tar.Z' rule still works too.
1228 * config.sub, configure: Roll in latest from ..
1230 Thu Sep 19 17:41:24 1991 Roland H. Pesch (pesch at cygnus.com)
1232 * doc/gdbint.texinfo: Reorder contents; reorganize new-host,
1233 new-target, and new-config chapters; fix minor typos; come closer
1234 to usual GNU markup conventions for @file @samp @code @var.
1236 Thu Sep 19 17:04:12 1991 Per Bothner (bothner at cygnus.com)
1238 Patches from Peter Schauer <pes@regent.e-technik.tu-muenchen.de>:
1239 * mipsread.c (parse_partial_symbols): Enter the name of all
1240 structs/unions... into the psymtab so we can access them if the
1241 symtab is not read in.
1242 * mips-tdep.c: Remove some unneeded #includes.
1243 * xconfig/dec3100: Add HAVE_STRSTR.
1245 Thu Sep 19 15:14:23 1991 John Gilmore (gnu at cygnus.com)
1247 * Makefile.in: Circumvent Sun Make bug on *-exp.tab.o.
1248 * c-exp.y, m2-exp.y: Lint.
1249 * m2-exp.y: Avoid using yytname[] which is a Bison-ism.
1250 * valprint.c (val_print_fields): Check for stub type.
1251 * mipsread.c (_initialize_mipsread): Avoid using
1252 builtin_type_void at initialize time.
1253 (mipscoff_symfile_read): use it now.
1255 Wed Sep 18 15:55:51 1991 John Gilmore (gnu at cygnus.com)
1257 Merge multiple-language support, and partial Modula-2 support,
1258 from Andrew Beers <beers@cs.buffalo.edu>.
1260 * i387-tdep.c: New file, consolidates most 80387 support,
1261 and eliminates host dependency on double<->extended conversions.
1262 * i386-xdep.c, symm-xdep.c: Remove most 387 support.
1263 * xconfig/i386{sco,v,v-g,v32,v32-g}: Now need i387-tdep.o.
1265 * symfile.c (allocate_symtab): New fn, consolidates the work
1266 of allocating and initializing a new struct symtab. Set the
1267 language of the symtab based on its filename extension.
1268 * symfile.h: Declare it.
1269 * mipsread.c (new_symtab): Use it. Minor formatting changes.
1270 * dbxread.c (end_symtab): Use it.
1272 * mipsread.c (parse_symbol, case stParam and stProc): Add #if 0'd
1273 code for saving types of parameters with each function definition.
1274 * dbxread.c (define_symbol, function and parameter cases): Ditto.
1275 (read_dbx_symtab, case N_DEFD): Ignore.
1276 (read_enum_type): Recognize FALSE/TRUE enum as Modula-2 BOOLEAN.
1277 (read_range_type): Rename MAX_OF_TYPE to MAX_OF_C_TYPE, etc.
1278 #if 0 out its uses, though, since they set a dead value.
1279 * coffread.c (end_symtab): Use allocate_symtab.
1280 (process_coff_symbol): #if 0'd for functions and params as above.
1281 (read_enum_type): Recognize Modula-2 BOOLEAN.
1282 * symtab.c (add_param_to_type): #if 0'd function to add a
1283 parameter type to a function type's field list.
1285 * defs.h (local_hex_format, local_hex_string, *_custom): Add.
1286 * i386-xdep.c, pyr-tdep.c, pyr-xdep.c, remote-vx.c, solib.c,
1287 source.c, symfile.c, dbxread.c, breakpoint.c, core.c, exec.c,
1288 i387-tdep.c, infcmd.c, mips-tdep.c, stack.c, printcmd.c: Output
1289 hex with local_hex_string for Modula-2 support.
1291 * breakpoint.c (breakpoint_cond_eval): Use new value_true to test
1292 breakpoint condition language-independently.
1294 * parse.c: New file with the common code remains of expread.y.
1295 * parser-defs.h: New file with common declarations from expread.y.
1296 * c-exp.y: New file with the C parser from expread.y, and other

1354 Tue Sep 17 08:37:41 1991 John Gilmore (gnu at cygint.cygnus.com)
1356 Add Andrew Beers' changes for Modula-2 support. His ChangeLog
1357 entries are enclosed herein. Not all of these changes
1358 have been merged into the master GDB sources -- check the
1359 ChangeLog above here for the merge log.
1361 Mon Jun 3 17:05:45 EDT 1991
1363 m2-exp.y Created. Tested outside of GDB for a few days. Proper
1364 operators were added, C specific operators and tokens
1365 removed. yylex() revamped to some extent. Still things
1366 missing from the grammar, such as sets.
1367 Tested for two weeks in GDB v3.5.
1369 Tue Jun 11 17:23:48 EDT 1991
1371 m2-exp.y Added boolean constants TRUE and FALSE to the grammar
1372 so they are built-in. Sort of a hack.
1374 Fri Jun 14 12:53:51 EDT 1991
1376 m2-exp.y Added range checking for numeric constants. Any numeric
1377 constant is assumed to be of builtin type INTEGER unless:
1378 (1) it is octal or hexadecimal, in which case it is a
1379 CARDINAL; (2) it is too big to fit into an INTEGER, in
1380 which case it is a CARDINAL.
1381 eval.c Added simple range checking for +, -, and * on integers.
1382 Doesn't work very well for *, since 6 * 1,000,000,000 =
1383 1,705,032,704, which fails the simple test of result >=
1384 first_operand, no matter in what order the operands are.
1386 Tue Jun 18 14:11:30 EDT 1991
1388 Broke the parser into parts, one containing the C grammar and the other
1389 containing code to be shared by all of the grammars.
1391 The following files no longer exist:
1396 The following files were added:
1398 c-exp.y (The C grammar)
1399 m2-exp.y (The Modula-2 grammar)
1400 parser-code.c (Code that is shared by the above grammar)
1404 Makefile.dist Changed to reflect the above dependencies. NOTE: It is
1405 now necessary to use the Bison compiler compiler, since it
1406 will generate function/variable prefixes other than yy.
1408 Tue Jun 18 16:47:49 EDT 1991
1410 symtab.[ch] Added the external variable working_lang, than holds the
1411 value of the current working language.
1412 Added the ennumerated type language_mode, with the values
1413 language_auto and language_manual, the former meaning that
1414 GDB sets working_lang as needed, and the latter meaning
1415 that the value of working_lang is totally under user
1417 symtab.[ch] Added the Modula-2 pervasive types INTEGER, CARDINAL,
1418 REAL, BOOLEAN and CHAR. Also added the type codes
1419 TYPE_CODE_BOOL and TYPE_CODE_CHAR.
1420 utils.c Added set_language_command and show_language_command to
1421 implement the GDB support commands "set language" and
1423 expression.h A number of identifiers were added to the type exp_opcode
1424 to facilitate Modula-2 builtin functions, integer
1425 division, and array indexing.
1427 Wed Jun 19 13:25:58 EDT 1991
1429 language.h Added the macro STRICT_TYPE, which evaluates to non-zero
1430 if the language specified by working_lang requires the use
1431 of strict typing of expressions. Eventually, even this
1432 will be able to be changed by the user.
1433 Added the macro RANGE_CHECK, which evaluates to non-zero
1434 if the language specified by working_lang requires the
1435 checking of a value against the domain of its type.
1436 Eventually, even this will be able to be changed by the
1438 language.[ch] Predicates involving types (simple_type, ordered_type,
1439 same_type, integral_type, numeric_type, character_type,
1440 boolean_type, float_type) are added. These predicates are
1441 based on the current value of working_lang, and are handy
1444 Wed Jun 19 15:39:34 EDT 1991
1446 eval.c Added the function type_array_rank which computes the rank
1448 valarith.c Added the funtion value_bool, which when given a integer
1449 value.h value (ie. struct value *) as an argument, it returns a
1450 boolean value (ie. struct value *) true if that integer
1451 is non-zero, and a boolean value false otherwise.
1452 valprint.c Added cases for TYPE_CODE_BOOL, so Modula-2 BOOLEAN values
1453 will print out properly.
1455 Wed Jun 19 16:36:34 EDT 1991
1457 valops.c Added the function value_capitalize, which returns it
1458 value.h argument capitalized if its argument is a lowercase
1459 letter, or the argument unchanged if its argument is not a
1461 valarith.c Added the function range_check_p, which returns non-zero
1462 value.h if its value argument is between the integral bounds upper
1464 Added the function range_check_enum_p, which makes sure
1465 that its value argument is a valid member of the domain of
1467 Added the function range_check_range_p, which makes sure
1468 its value argument lies between the upper and lower bounds
1469 of its type argument, which must be a ranged type.
1470 Added the function check_array_index, which range and type
1471 checks an index of an array.
1472 Added the function value_multi_subscript, which computes
1473 array[idx1,idx2...idxN], given a value array and an array
1474 of values representing indicies.
1475 values.c Changed value_from_long to work with TYPE_CODE_CHAR and
1476 unpack_long to work with TYPE_CODE_BOOL and
1479 Wed Jun 19 18:04:08 EDT 1991
1481 symtab.c Stored pervasive types in a structure and make
1482 lookup_pervasive_type() a lookup function that was based
1483 on working_lang. If lookup_pervasive_type() returned
1484 non-zero, then that value was returned (a fix, since
1485 before it simply wouldn't return the pervasive type.)
1486 language.h Added the macro CAST_IS_CONVERSION, which evaluates to
1487 non-zero if the language specified by working_lang means
1488 "conversion" when it says "cast".
1489 valops.c Added the function value_real_cast(), which performs a
1490 value.h *cast*, not a *conversion*, which is what value_cast()
1491 does when it can. In particular,
1492 value_cast(<float_type>,4) = 4.0, while
1493 value_real_cast(<float_type>,4) = some mess.
1494 eval.c Modula-2 builtin functions implemented: ABS, CAP, CHR,
1495 parser-code.c FLOAT, HIGH, MAX, MIN, ODD, ORD, TRUNC, and VAL.
1496 expression.h Added macros MAX_OF_TYPE and MIN_OF_TYPE to work with MAX
1497 and MIN on integral types. *NOTE*: These are currently
1498 hardcoded to work only if there are 8 bits per storage
1500 eval.c Made logical functions call value_bool to return a
1501 properly typed boolean value, based on working_lang.
1503 Thu Jun 20 11:55:27 EDT 1991
1505 valprint.c Types now print out in a Modula-2 fashion. This works for
1506 the cases when the type is printed out step-by-step, that
1507 is, it doesn't work when the name of a structured type
1508 (which includes the keyword "struct", etc.) is simply
1510 FIXME: Perhaps this is bad. Parts of it seem to kludgey,
1511 since type specifications in C and Modula-2 are very
1512 different. The C printing of a type is very recursive,
1513 whereas in Modula-2 it is generally very simple. C has
1514 type prefixes and suffixes, which have no real analogue in
1515 Modula-2. Maybe type_print() should call a language
1516 specific type printer. This is also advantageous if we
1517 compile GDB to exclude some of the languages. We'll just
1518 leave those functions out.
1520 Thu Jun 20 16:57:10 EDT 1991
1522 dbxread.c When reading the complete symbol table in (via
1523 psymtab_to_symtab()), the number and types of function
1524 arguments are added to a function type. define_symbol()
1525 calls add_param_to_type() to accomplish this.
1526 Assumption: when we come across a function definition
1527 (N_FUN symbol with an 'f' or 'F' in the name), its
1528 arguments will appear before another function definition.
1529 When a function is found, a pointer to its type is placed
1530 in the global in_function_type. Changes that
1531 add_param_to_type() makes are to this global.
1532 valprint.c The type of a function now includes (for Modula-2) the
1533 types of its parameters.
1534 eval.c Type checking and a check for the proper number of
1535 arguments is now done for function calls. Not sure of the
1536 impact this has on C++ member function yet.
1538 Thu Jun 20 19:58:48 EDT 1991
1540 valprint.c Rewrote the type printer. Broke it into two language
1541 specific parts, adding the functions type_print_m2() and
1543 An unfortunate consequence is this: if you debugging a C
1544 program in Modula-2 mode (why?), info types does not work
1545 well with regular expressions, since the types are printed
1546 out in Modula-2 terminology, but stored in C terminology.
1547 language.[ch] Added the functions new_type_last(), type_keyword(), and
1548 type_sep() to aid in the printing of typedefs.
1549 symtab.c Made the printing of typedefs as language independent as
1550 possible through calls to new_type_last(), type_keyword(),
1553 Fri Jun 21 11:50:26 EDT 1991
1555 dbxread.c Check all incoming ennumerated types. If it looks like
1556 Modula-2's BOOLEAN type, then change the type_code of the
1557 type to TYPE_CODE_BOOL so we can process it as a boolean
1559 valprint.c Replaced some of the 0x%x with calls to sprintf and
1560 hexformat() in val_print().
1561 language.[ch] Added the function hex_to_string(), which converts its
1562 integral argument to a hexadecimal number (format is
1563 language based) and returns the result as a string.
1565 Mon Jun 24 12:25:07 EDT 1991
1567 valprint.c Some functions call type_print_1() directly, instead of
1568 value.h using type_print(), so they can specify where (column) to
1569 print things. Since type_print() takes care of language
1570 dependence, that needs to be called first. Added a
1571 parameter depth to type_print() (so it is now like
1572 type_print_1). Changed type_print to type_print_at, and
1573 made type_print a macro that passes a depth argument of
1575 symmisc.c Changed all calls to type_print_1 to calls to
1577 Makefile.dist Made it possible to build GDB for a specific set of
1578 depend languages. Do this by passing a definition for the macro
1579 LANGS to make. LANGS should be a string containing a
1580 space-separated list of language names (ie. LANGS="c m2").
1581 The default is to build all languages. Note that grammar
1582 files must follow the naming convention of <lang>-exp.y.
1583 gdb.lang This holds the current value of the LANGS macro. It is
1584 examined every time make is called, and is updated if
1586 eval.c Added #ifdef _LANG_<lang> to these files.
1587 expread.c Still need to add them to dbxread.c and coffread.c.
1595 Mon Jun 24 16:33:11 EDT 1991
1597 language.[ch] Added the functions hexformat_pre() and
1598 hex_to_string_pre(), which take a prefix argument to
1599 include in the format string. Thus, hexformat_pre("08") will
1600 return "0x08x" (if the working language is language_c).
1601 Made hexformat() and hex_to_string() calls to the above
1602 with "" as the prefix argument.
1604 am29k-pinsn.c, arm-pinsn.c, breakpoint.c, convex-tdep.c, exec.c, core.c,
1605 dbxread.c, i386-pinsn.c, i386-stub.c, i386-xdep.c, i960-pinsn.c,
1606 infcmd.c, inflow.c, m68k-pinsn.c, m68k-stub.c, m88k-pinsn.c,
1607 mips-pinsn.c, mips-tdep.c, ns32k-pinsn.c, printcmd.c, pyr-pinsn.c,
1608 pyr-tdep.c, pyr-xdep.c, remote-vx.c, remote.c, solib.c, source.c,
1609 stack.c, sun386-xdep.c, symfile.c, symm-xdep.c, symmisc.c, tahoe-pinsn.c,
1610 valprint.c, vax-pinsn.c
1612 Changed all occurences of 0x%[0-9]*l*x in printf format strings to
1613 calls to hexformat() and hex_to_string(). Format strings without
1614 the leading "0x" were ignored.
1616 depend Updated to take the above into account.
1619 Tue Jun 25 15:27:18 EDT 1991
1621 symtab.h Added the types range_mode_t, range_check_t, type_mode_t,
1622 and type_check_t to keep track of the current state of
1623 range and type checking.
1624 main.c Added the variables range_mode, range_check, type_mode,
1625 and type_check to record the current state of range and
1626 type checking. Added initialization code to main().
1627 language.h Changed the macros STRICT_TYPE and RANGE_CHECK to examine
1628 the above variables.
1631 Tue Jun 25 17:57:08 EDT 1991
1633 dbxread.c process_one_symbol() updates the variable (enum language)
1634 source_lang based on the extension of the filename
1635 contained in the N_SO sybmol that started this symtab.
1636 When end_symtab() is called, the value of source_lang is
1637 put into the language field.
1638 stack.c select_frame() sets working_lang (and possibly type_check
1639 and range_check) to the language field of the symtab
1640 associated with the frame that is selected if working_mode
1641 is language_auto. If working_mode is language_manual, a
1642 warning is printed and working_lang is not set.
1643 language.c Added the function set_type_range(), which sets the value of
1644 type_check and range_check (if their modes call for
1645 automatic setting) based on the current value of
1646 working_lang. A non-zero argument will cause the current
1647 settings to be output.
1650 Wed Jun 26 14:51:40 EDT 1991
1652 eval.c Added range checks on assignment.
1653 m2-exp.y Added the grammar for sets to the language. Currently,
1654 these do not do anything except print an error message.
1656 Wed Jun 26 17:01:04 EDT 1991
1658 m2-exp.y Added the ability for parse_number() to parse negative
1659 numbers. A global flag is set upon encountering a unary
1660 minus. This was done to make, for example, 1 parse as a
1661 CARDINAL, and not as an integer, per Wirth's examples in
1662 Programming in Modula-2 ed.4.
1663 valprint.c Added support for "set radix 2" by then setting
1664 output_format to 't'.
1665 eval.c Implemented range checking on subrange types. Added calls
1666 to range_check_range_p for BINOP_ASSIGN and BINOP_VAL.
1667 Implemented MIN and MAX for ennumerated types. The
1668 minimum value of an ennumerated type is defined by Wirth
1669 as the first identifier, and the maximum as the last.
1670 m2-exp.y Made octal numbers ending with "B" be characters and those
1671 ending with "C" be numbers, per Wirth's book. (p. 34)
1673 Thu Jun 27 14:11:52 EDT 1991
1675 stack.c select_frame() now only sets working_lang, it does not
1676 notify the user. If working_mode is language_manual, then
1677 a warning is issued once.
1678 main.c At the end of each call to execute_command(), working_lang
1679 is checked against the local static (enum language)
1680 current. If they differ and working_mode is
1681 language_auto, the new settings of language, type and
1682 range checking are printed out.
1683 stack.c Modified frame_info() to include the language of the
1684 current frame in the output of "info frame".
1685 language.[ch] Added the function language_str() which returns the name
1686 of the current language.
1688 Fri Jun 28 15:33:14 EDT 1991
1690 m2-exp.y Added the built-in procedures INC, INCL, DEC, and DECL to
1691 the language. INCL and DECL currently cause an error,
1692 since sets are not implemented yet. INC and DEC are
1693 implemented as PREINCREMENT/PREDECREMENT with one
1694 argument, and as ASSIGN_MODIFY with two arguments.
1695 eval.c Added type checking to the above cases.
1696 value.h Added not_lval_constant to the lval_type ennumerated type.
1697 not_lval_constant means that the value is a constant
1698 value; that is 3 or 'a' or TRUE, not as in a constant
1699 identifier. This is used to help coerce numbers such as 3
1700 to either signed or unsigned numbers.
1701 valops.c Added the function value_coerce_constants() which coerces
1702 constant integers as following: if one is a constant and
1703 the other is not, the constant's type is set to the type
1704 of the other argument. If both are constants and one is
1705 signed, the other is converted to a signed constant.
1707 Sat Jun 29 17:26:29 EDT 1991
1709 valarith.c Added a better range checker. It now checks range
1710 (successfully) on integral operations [+-] (signed and
1711 unsigned) for any C sized type. Still does not work well
1712 for multiplication.)
1713 int_in_size() returns an integer that is coerced to fit into
1714 specified number of bytes.
1716 Mon Jul 1 13:04:14 EDT 1991
1718 language.[ch] Added the function binop_result_type(), which returns the
1719 builtin (struct type *) type that would be the result of a
1720 binop on the two values V1 and V2.
1722 Wed Jul 3 19:22:53 EDT 1991
1724 source.c Extended source_info() to include the source language in
1725 the output from "info source".
1727 Fri Jul 5 13:48:52 EDT 1991
1729 utils.c Moved the support functions for the GDB set/show commands
1730 dealing with language into language.c.
1731 language.c Added the function language_info(), which displays info
1732 about the current working language, type and range check
1733 settings. Called via the GDB command "info language".
1734 Added an initialization routine _initialize_language(),
1735 that sets defaults for the language, type and range
1736 variables and sets up the new GDB commands.
1737 main.c Language setup moved to language.c.
1740 Mon Jul 8 10:10:22 EDT 1991
1742 valarith.c Debugged the range checker for arithmetic. Still does not
1743 work for multiplication very well.
1745 Mon Jul 8 12:40:37 EDT 1991
1747 language.[ch] Added the function value_true() which returns non-zero if
1748 its argument represents a boolean true value.
1749 breakpoint.c Changed breakpoint_cond_eval() to call value_true() to
1750 check the truth of an expression.
1752 Thu Jul 11 12:51:34 EDT 1991
1754 language.[ch] Added the predicate structured_type(), which returns
1755 non-zero if the argument is a structured type.
1756 Added the predicate pointer_type(), which returns non-zero
1757 if the argument is a pointer type.
1758 eval.c Added the ability to do addition and substraction on
1759 pointers and integers. This case simply bypasses the
1762 Thu Jul 11 14:41:42 EDT 1991
1765 Added the symbol N_DEFD (0x4a) which is a definition
1766 module dependency that is used by the GNU Modula-2
1767 compiler and the linker. It is not important to GDB,
1768 except that [dbx|coff|mips]read.c should ignore these
1771 Fri Jul 12 16:07:00 EDT 1991
1773 valprint.c Changed the TYPE_LENGTH(type) >= 0 to TYPE_LENGTH(type) >
1774 0 in val_print(). Also added statements to the else part
1775 to coerce type (argument to val_print) to a pointer type
1776 if it is an "array of unspecified length".
1777 valops.c Added the function value_m2_string(), which returns a
1778 (value) value which is a constant string, whose type is
1779 (ARRAY [0..n] OF CHAR). The length field of the type
1780 structure is set to zero, so it will be interpreted as an
1781 "array of unspecified length".
1782 stack.c Moved the language/frame mismatch check to
1783 main.c:execute_command().
1784 main.c The working language is recorded each time
1785 execute_command() is executed. If working lang has
1786 changed during its execution, then the new
1787 language/type/range info is printed out for the user. If
1788 the working language does not match the language of the
1789 frame, a warning is issued.
1791 Sat Jul 13 16:16:39 EDT 1991
1793 eval.c Moved all the type-checking stuff for operators to
1794 language.[ch] language.c. This is so we can keep language-specific
1795 stuff (like for what type operators are defined) in
1797 language.[ch] Added the function binop_type_check(), which checks to see
1798 if its two (value) arguments are type-compatible with its
1799 opcode argument. The opcode should represent an operation
1800 involving an operator. Also added the macro function
1801 unop_type_check, which calls binop_type_check with a
1802 NULL second argument.
1803 expprint.c Added Modula-2 operators to the op_print_tab, so info
1804 expression.h break works correctly. Also added "op_string", which
1805 returns the string corresponding to the (enum exp_opcode)
1806 opcode that is its argument.
1809 Sat Jul 13 18:26:18 EDT 1991
1811 coffread.c Added code to record the type of function arguments with
1812 each paricular function. Code is very similar to that
1814 dbxread.c Moved add_param_to_type() to symtab.c
1815 symtab.[ch] Added function add_param_to_type() from dbxread.c
1817 *** NOTE: The above additions have not been tested.
1819 Mon Jul 15 12:50:47 EDT 1991
1821 langauge.[ch] Added the functions type_error and range_error, which work
1822 like error() except if the type/range mode is set to
1823 *_mode_warn, then they do not do a return_to_top_level(),
1824 but merely print a warning.
1825 Also changed [set|show]_[type|range]_command() to support
1826 the new "warn" feature.
1828 Thu Jul 18 17:50:54 EDT 1991
1830 mipsread.c Added code to record the type of function arguments with
1831 each particular function. Code is very similar to that
1834 *** NOTE: The above additions have not been tested.
1836 Fri Jul 19 11:19:10 EDT 1991
1838 defs.h Added macros MAX_OF_SIZE, MIN_OF_SIZE, UMAX_OF_SIZE, and
1839 UMIN_OF_SIZE, which when given a size of a numeric type,
1840 return the maximum and minimum value it can hold. UMAX...
1841 and UMIN... return the result for unsigned types.
1842 symtab.h Added the macros MAX_OF_TYPE and MIN_OF_TYPE to operate on
1843 struct types. They call above macros.
1844 dbxread.c Renamed the MAX and MIN_OF_TYPE macros to ..._OF_CTYPE to
1845 avoid a name conlict with the above.
1846 c-exp.y Added range checking on numeric constants in
1847 parse_number() for completeness.
1848 valarith.c Made binop_user_defined_p() and unop_user_defined_p()
1849 return 0 if working_lang is not language_c.
1851 Thu Aug 8 14:17:22 EDT 1991
1855 breakpoint.c Documentation strings of some commands changed to
1856 eliminate the references to the C language where
1859 Tue Aug 13 15:48:03 EDT 1991
1861 m2-exp.y Added qualified identifiers to the grammar. The semantics
1862 are slightly different from those of the GDB operator ::
1864 m2-exp.y Added a rule to each grammar of the form: start ::= exp |
1865 type_exp, where type_exp is any valid type expression.
1867 eval.c Added the opcode OP_TYPE, and an error case in eval.c.
1868 printcmd.c Modified ptype_command() so it actually parses the input
1869 (necessary for type expressions with scope qualifiers).
1870 Added the function ptype_eval() which expects an
1871 expression composed of one OP_TYPE element.
1872 *.[ch] Replaced all occurences of parse_c_expression with
1874 *.[ch] Replaced all occurences of parse_c_1 with parse_exp_1
1876 [End of ChangeLog entries from Andrew Beers for Modula-2 support.]
1878 Mon Sep 16 17:19:46 1991 John Gilmore (gnu at cygnus.com)
1880 Small fixes from Peter Schauer:
1882 * infrun.c (child_attach): Lint.
1883 * solib.c (find_solib): Handle shared libs version 2.
1885 Small fixes from David Wood:
1887 * xm-ultra3.h (SYS_SIGLIST_MISSING): Typo.
1891 * remote-vx.c: Move <stdio.h> to top, for FILE. Fix from
1892 John S <basrai%kanga.dnet@c3po.sm-alc.af.mil>.
1894 * utils.c (wrap_here): Avoid wrap action of fputs_filtered if
1895 chars_per_line is at maximum (user typed `set width 0'). Fix
1896 from Andreas Schwab <schwab@ls5.informatik.uni-dortmund.de>.
1898 Tue Sep 17 17:31:04 1991 Stu Grossman (grossman at cygnus.com)
1900 * coredep.c: include ptrace.h where necessary.
1901 * mipsread.c(parse_lines): fix unsigned char problem that was
1902 messing up line numbers on SGI's and possibly other MIPS based
1904 * infrun.c (child_create_inferior): use better test to check
1905 return val from setpgrp().
1906 * tm-irix3.h, xm-irix3.h, tconfig/irix3, xconfig/irix3: add these
1907 for sgi/irix support.
1909 Wed Sep 18 04:33:31 1991 Per Bothner (bothner at cygnus.com)
1911 * mipsread.c (parse_symbol): Put non-static procedures
1912 in the global block.
1914 Fri Sep 13 00:14:52 1991 John Gilmore (gnu at cygnus.com)
1916 Patch together `text_start' and `text_end' for 29K port.
1918 * exec.c (exec_command): If NEED_TEXT_START_END, define the
1919 variables and set them based on the exec file.
1920 * am29k-tdep.c: declare text_start.
1921 * valops.c (call_function_by_hand): declare text_end.
1923 * inferior.h: Eliminate CANNOT_EXECUTE_STACK in favor of
1924 defining CALL_DUMMY_LOCATION as BEFORE_TEXT_END. This is
1925 because machines that do this will also have to know to
1926 set NEED_TEXT_START_END. Besides, it was a redundant way to
1928 * tm-29k.h, tm-convex.h, tm-np1.h: Eliminate
1929 CANNOT_EXECUTE_STACK, define CALL_DUMMY_LOCATION and
1930 NEED_TEXT_START_END.
1932 Thu Sep 12 00:22:24 1991 John Gilmore (gnu at cygint.cygnus.com)
1934 AMD 29000 changes from David Wood <wood@david.ultra.nyu.edu>:
1936 * Makefile.in (CLIBS): Put XM_CLIBS and TM_CLIBS at end.
1937 Pass MUNCH_DEFINE to munch whenever we run it.
1938 * am29k-pinsn.c (print_insn): Handle NOP specially. Avoid %#x
1939 format string; use 0x%x instead.
1940 * am29k-tdep.c: Use DUMMY_SAVE_GREGS and RETURN_REGNUM.
1941 * ultra-xdep.c, xm-ultra.h: New files for Ultracomputer host system.
1942 * xm-rtbsd.h: New host support for RT/PC running BSD Unix.
1943 * inflow.c: Handle `short' process group IDs.
1944 * infptrace.c (fetch_register): Support CANNOT_FETCH_REGISTER,

1947 (coff_symfile_init): Initialize text_bfd_scnum.
1948 (read_coff_symtab): Use it to find the text [and absolute?] sections.
1949 * ../config.sub: Add vendor nyu and os "sym[1-9]*".
1950 * configure.in: Add hosts rtpc-*-* and a29k-*-*.
1951 Merge target arm case with other "easy" cases. Add target
1952 cases a29k-*-none (rehack of am29k), a29k-*-kern (remote to
1953 Ultracomputer kernel), and a29k-*-sym1 (ultracomputer OS's user
1955 * minimon.h, remote-adapt.c, remote-mm.c: Add.
1956 * munch: Cope with RT/PC putting fns in data segment.
1957 Restore ability to override `nm' by specifying MUNCH_NM.
1958 * xconfig/rtbsd, xconfig/ultra3: New host systems.
1959 * tconfig/a29k: Rename from tconfig/am29k. Add remote-mm
1960 and remote-adapt. Remove encapsulated coff #define's (the
1961 support should go in BFD, and gdb shouldn't know or care).
1962 * tconfig/a29k-kern: Same, but for remote kernel debugging.
1963 * tconfig/ultra3: For debugging user processes on Ultra3/Sym1.
1964 * tm-29k.h: Update BADMAG (though it should go away).
1965 Allow the register definitions to be overridden in another
1966 tm-file. Fix SR_REGNUM. Add a mess of _REGNUM's. Separate
1967 RETURN_REGNUM from GR96_REGNUM and DUMMY_SAVE_GREGS from
1968 DUMMY_SAVE_GR96, for handling kernel calling conventions
1969 that use GR64+ rather than GR96+.
1970 * tm-ultra3.h: New file, for use on Ultra3 Unix as well as for
1971 remote debugging of Ultra3 kernel. Includes tm-29k.h and
1972 overrides various things.
1974 * remote-mm.c (mm_attach, mm_wait): Handle attach like
1975 child_attach does, making a clean stop in the newly attached
1977 * remote-eb.c: Lint.
1979 * coffread.c: Make coffread independent of any particular
1980 variant of COFF. Avoid #include-ing any particular one except
1981 internalcoff.h. BFD now passes key values for symbol reading
1982 as part of its coff_data structure (LINESZ, SYMESZ, AUXESZ,
1983 and the symbol masks and shifts); use them.
1984 Remove obsolete end_of_text_addr.
1986 * exec.c: Remove unused include files.
1988 Wed Sep 11 19:38:44 1991 John Gilmore (gnu at cygint.cygnus.com)
1990 * Makefile.in (documentation targets): Pass $(M4).
1991 Bugfix from eggert@twinsun.com (Paul Eggert).
1993 * stack.c (down_silently_command): Check for stack existence.
1995 Tue Sep 10 23:08:29 1991 John Gilmore (gnu at cygint.cygnus.com)
1997 * Makefile.in (VERSION): Update to 4.0.3.
1999 Tue Sep 10 09:19:29 1991 John Gilmore (gnu at cygint.cygnus.com)
2001 * core.c (core_file_command): Print frame at coredump with
2002 its level number, by calling print_stack_frame.
2003 * frame.h: Add selected_frame_level, print_stack_frame.
2004 * frame.h, stack.c: Remove print_sel_frame, print_selected_frame.
2005 * convex-tdep.c, convex-xdep.c, infcmd.c, inflow.c, infrun.c:
2006 Change print_sel_frame and print_selected_frame callers to
2009 * dbxread.c (read_ofile_symtab): Avoid empty else clause.
2010 * symfile.c (free_named_symtabs): Ditto.
2011 * main.c (main): wrap_here needs an arg.
2012 * solib.c (find_solib): Avoid memory access if _DYNAMIC is zero.
2013 (solib_add): Avoid noise.
2014 (solib_create_inferior_hook): Lint.
2015 (sharedlibrary_command): Move dont_repeat to here.
2016 * utils.c (error): Call wrap_here to force buffered output.
2018 Small patches from Peter Schauer:
2020 * coffread.c (start_symtab): Free any existing line_vector before
2022 (read_coff_symtab): Ditto for type_vector.
2024 * source.c (lines_to_list): New variable, replacing function.
2025 (all uses): Use as variable.
2026 (_initialize_source): Add 'set listsize' and 'show listsize'.
2027 * utils.c (lines_to_list): Remove function.
2028 * stack.c (print_frame_info): Use as variable.
2029 * defs.h (lines_to_list): Remove declaration.
2031 Mon Sep 9 13:45:57 1991 John Gilmore (gnu at cygint.cygnus.com)
2033 * breakpoint.c (insert_breakpoints): Restore warning about
2034 the program might be running in another process, but only for
2035 systems with this brain death (#ifdef ONE_PROCESS_WRITETEXT).
2036 * xm-hp300bsd.h, xm-mips.h, xm-vax.h: Define it.
2038 * utils.c (error): if error_pre_print is set, print the string
2040 * main.c (main, print_gnu_advertisement, print_gdb_version):
2041 Reformat legalese so it always prints, but acts as an "I'm here"
2042 message while symbols are being read. If any errors occur,
2043 print a few newlines to set off the message and start it at the
2044 left margin. Remove mention of "help" command, and don't yak
2045 about symbol reading.
2046 (catch_errors): Error string is now printed first in case of
2048 * command.c (undef_cmd_error, lookup_cmd): On undefined command,
2049 suggest the "help" command.
2051 * Makefile.in (VERSION): Set to 4.0.2.
2053 Thu Sep 5 23:49:48 1991 John Gilmore (gnu at cygint.cygnus.com)
2055 * .gdbinit: Remove useless "rr" command. Set complaints
2056 to 1 for people debugging gdb.
2058 * breakpoint.c, remote-vx.c: Reword strings printed by
2059 catch_errors callers.
2061 Wed Sep 4 11:07:50 1991 John Gilmore (gnu at cygint.cygnus.com)
2063 * WHATS.NEW: "history write -> history save". Doc "write on/off".
2064 (Fix from kenc@viewlogic.com.)
2066 Fix some infrastructure to be able to cope with host and target
2067 machines with different sized basic types (ints, ptrs, etc).
2068 (Idea from pierre@la.tce.com (Pierre Willard).)
2070 * values.c (value_from_longest): Rename from value_from_long.
2071 Handle pointer types as well as integers, so that targets with
2072 different pointer sizes from the host can be accomodated.
2073 * breakpoint.c, convex-tdep.c, eval.c, expprint.c, printcmd.c,
2074 valarith.c, valops.c, valprint.c, value.h, values.c: Rename
2075 uses of value_from_long to value_from_longest.
2076 * eval.c, findvar.c, printcmd.c, valarith.c, valops.c: Pass
2077 the correct pointer type to value_from_long{est}.
2079 * doc/gdb.texinfo ($_, $__): Describe types of these variables.
2081 * remote-vx.c: Remove obsolete code for calling functions via
2082 vxworks kludge interface (it referenced value_from_long).
2084 * valops.c (value_string): Find malloc with lookup_misc_func, not
2087 Tue Sep 3 18:37:46 1991 John Gilmore (gnu at cygint.cygnus.com)
2089 Make writing to files work properly. (Fixes to BFD are also needed.)
2091 * core.c (core_open): Open file ourselves, read or r/w, depending on
2092 write_files. Use bfd_fdopenr.
2093 * gdbcore.h (write_files): New variable.
2094 * exec.c (write_files): Define variable, add set&show for it.
2095 (exec_file_command): Use write_files to open for read or r/write.
2097 Make shared library reading happen automatically. These changes
2098 are mostly from Peter Schauer <pes@regent.e-technik.tu-muenchen.de>.
2100 * inferior.h (stop_soon_quietly): Add to exported variables.
2101 * infrun.c (child_create_inferior): call solib hook, if defined.
2102 (child_attach): call solib hook, if defined.
2103 * solib.c: Include inferior.h. Add from_tty to so_list as kludge.
2104 (find_solib): Use lookup_misc_func rather than hand-rolled.
2105 (symbol_add_stub): New stub for catch_errors.
2106 (solib_add): Avoid output if !from_tty. Catch errors rather
2107 than just calling symbol_file_add and bombing.
2108 (solib_create_inferior_hook): Interface with the target process
2109 to let it read and alloc shared libs, then figure out what it did.
2111 * core.c (validate_files): Fix typo, soften warning.
2112 (Fix from Hiroto Kagotani <kagotani@cs.titech.ac.jp>.)
2114 * utils.c (fputs_demangled): Avoid duplicate printing if
2115 demangling is off. (Fix from J.T. Conklin <jtc@cayenne.com>.)
2117 * infrun.c (proceed): Cast -1 to (CORE_ADDR) before comparing.
2118 (Fix from pierre@la.tce.com (Pierre Willard).)
2120 * main.c (catch_errors): Change argument to a char * from an int,
2121 since a char * can point to a struct full of glop, but an int
2122 is not guaranteed to be able to hold a pointer.
2123 * breakpoint.c (breakpoint_cond_eval, bpstat_stop_status,
2124 breakpoint_re_set_one, breakpoint_re_set): Adapt.
2125 * core.c (core_open, solib_add_stub): Adapt.
2126 * remote-vx.c (symbol_stub, add_symbol_stub, callers): Adapt.
2128 Wed Aug 28 18:18:05 1991 John Gilmore (gnu at cygint.cygnus.com)
2130 * Makefile.in: Update VERSION to 4.0.1. Evade GNU Make bug
2131 by adding .NOEXPORT target.
2133 Fri Aug 23 17:14:25 1991 John Gilmore (gnu at cygint.cygnus.com)
2137 * Makefile.in (VERSION): Roll to 4.0.
2138 (gdb.tar.Z): Make refcard.ps as well, for shipment.
2140 Fri Aug 23 14:07:09 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
2142 * doc/gdb.texinfo: minor rewordings, crossref to ptype from print,
2145 * doc/Makefile, Makefile.in: generate "gdb-all.texi" rather than
2148 * doc/rdl-apps.texi: renamed from rdl-apps.texinfo
2150 * Makefile.in, doc/Makefile, doc/.Sanitize, doc/gdb.texinfo:
2151 reflect above name change
2153 * WHATS.NEW: correct pointer to refcard.
2155 * doc/gdb.texinfo: update New Features, Installing
2157 * doc/gdbint.texinfo: add short description of configure +template
2159 Fri Aug 23 11:46:08 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
2161 * doc/gdb.texinfo: update, fix bugs in "Installing" appendix
2163 Fri Aug 23 01:02:00 1991 John Gilmore (gnu at cygint.cygnus.com)
2165 * Makefile.in: Add config.sub, make doc/rdl-apps.texinfo for
2166 tar file, add dependencies for referenced doc files.
2168 Thu Aug 22 22:17:06 1991 Stu Grossman (grossman at cygint.cygnus.com)
2170 * coffread.c, symfile.c, stack.c: saberized.
2172 Thu Aug 22 16:20:27 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
2174 * doc/refcard.tex: permuted Essential Commands sec
2176 * doc/gdb.texinfo: new C++ chapter; revised installation appendix;
2178 set/show symbol-reloading
2179 default set complaints 0
2181 RET-repeat disabled after prompted long displays
2182 processID (attach) interpretation of 2nd GDB cmdline arg
2184 Thu Aug 22 14:05:47 1991 Stu Grossman (grossman at cygint.cygnus.com)
2186 * expread.y, coffread.c, dbxread.c, target.c, mem-break.c,
2187 cplus-dem.c, values.c, valprint.c, symfile.c, remote.c,
2188 breakpoint.c, main.c: lint.
2190 Thu Aug 22 02:02:26 1991 John Gilmore (gnu at cygint.cygnus.com)
2192 Install new configuration scheme for GDB and friends.
2194 * config.sub: Translate ordinary names to three-part names.
2195 * configure: Use three-part names internally.
2196 * configure.in: Translate three-part names to filenames.
2198 * README, WHATS.NEW: Update for gdb-4.0.
2199 * Makefile.in: Roll VERSION to 3.99.
2201 Wed Aug 21 18:21:09 1991 John Gilmore (gnu at cygint.cygnus.com)
2203 * infptrace.c (KERNEL_U_ADDR_BSD): Include a.out.gnu.h.
2204 * i960-tdep.c, m68k-tdep.c, sparc-tdep.c, tm-i960.h,
2205 tm-m68k.h, remote-nindy.c: Change ext_format_XXX structs
2206 to single structures rather than arrays; when passing
2207 their address, use &. This avoids trouble with bdead compilers.
2208 * mcheck.c: Don't include <stdlib.h>; just declare "void abort();"
2209 instead. This avoids portability headaches.
2210 * mips-tdep.c (mips_do_registers_info): Only print FP regs if
2212 * source.c (open_source_file): Avoid ANSI const bdeath by
2213 skipping declaration and then casting result value.
2214 * tm-hp300bsd.h: Clarify comment.
2215 * utils.c (strstr): Result is const char *; ANSI bdeath.
2216 * xm-hp300bsd.h: Define HOST_BYTE_ORDER. Redefine INT_MIN,
2217 since system include file defines it differently from "defs.h",
2218 though the two are equivalent for our purposes.
2219 * tconfig/hp300bsd: Add m68k-tdep.o.
2221 Tue Aug 20 16:01:11 1991 John Gilmore (gnu at cygint.cygnus.com)
2223 * tconfig/sun*4: Remove warnings about system assembler.
2225 Mon Aug 19 13:44:46 1991 John Gilmore (gnu at cygint.cygnus.com)
2227 * mcheck.c: Avoid warning about undeclared abort fn.
2228 * tm-sparc.h (PC_ADJUST): Avoid calling error() from this;
2229 it causes recursive calls to error() when used in cleanups.
2230 To do so requires that we make it a function, so we do.
2231 * sparc-tdep.c (sparc_pc_adjust): New implem of PC_ADJUST.
2232 * utils.c (do_cleanups): Remove the current cleanup from the
2233 chain *before* calling it, in case error() is called from it.
2234 The result won't be pretty, but won't be an infinite loop either.
2236 Mon Aug 19 00:41:04 1991 Michael Tiemann (tiemann at cygint.cygnus.com)
2238 * dbxread.c (read_struct_type): Grok anon structs for C++.
2239 (vb_name, vptr_name): Null terminate these strings.
2241 Fri Aug 16 08:31:03 1991 John Gilmore (gnu at cygint.cygnus.com)
2243 Minor bug fixes from BSD Net2 gdb:
2245 * blockframe.c (get_prev_frame_info): If FRAME_CHAIN_COMBINE
2246 returns 0, there is no previous frame.
2247 * breakpoint.c (commands_command): If !from_tty, don't call
2248 input_from_terminal_p().
2249 * dbxread.c (record_misc_function): Speed up slightly.
2250 (compare_psymbols): Ditto.
2251 * infcmd.c (do_registers_info): Take a second argument to
2252 determine whether to print float registers. "info registers"
2253 does not do so anymore. "info all-registers" does, now.
2254 * mips-tdep.c, pyr-tdep.c (xxx_do_registers_info): Take second
2256 * tm-mips.h, tm-pyr.h (DO_REGISTERS_INFO): Pass second arg.
2257 * inflow.c (initialize_inflow): Set tflags_ours correctly.
2261 * breakpoint.c (bpstat_do_actions): Use a cleanup to restore
2262 executing_breakpoint_commands if we are interrupted by error.
2263 * coffread.c (init_lineno): Avoid problem with zero-sized linetab
2264 versus malloc/free. From: john@labtam.labtam.oz.au (John Carey).
2265 * core.c (solib_add_stub, core_open): Call SOLIB_ADD inside a
2266 catch_errors() so we can setup the frame regardless of whether
2267 the shared libs work.
2268 * ieee-float.c (double_to_ieee_extended): Get exponent from
2269 right place in little-endian systems. From John Carey.
2271 Thu Aug 15 18:43:57 1991 John Gilmore (gnu at cygint.cygnus.com)
2273 * main.c: Remove unused terminating_signals and catch_termination().
2274 (long_options): Terminate with a zero element.
2275 [Bugfix from Atsuo Kawaguchi <atsuo@hark86.harl.hitachi.co.jp>.]
2276 (gdb_readline): Make call-compatible with readline.
2277 (init_signals): Improve comments re vfork vs. signal.
2279 * utils.c (prompt_for_continue): Use new gdb_readline().
2280 If we prompt for continuation, we don't let CR repeat the previous
2281 command, once we get back to a prompt. It's too easy to keep
2282 hitting CR, expecting "--more--" prompts, and have some long
2283 command start repeating on you.
2285 Tue Aug 13 16:17:56 1991 John Gilmore (gnu at cygint.cygnus.com)
2287 * blockframe.c (frameless_look_for_prologue): Speed up by
2288 calling SKIP_PROLOGUE_FRAMELESS_P if it's defined.
2289 * tm-sparc.h (SKIP_PROLOGUE, SKIP_PROLOGUE_FRAMELESS_P):
2290 Define two variants, one faster.
2291 * sparc-tdep.c (sparc_frame_chain): Use target_read_memory
2292 and return zero, rather than giving an error.
2293 (setup_arbitrary_frame): Initialize the PC in the new frame.
2294 (skip_prologue): Add a second arg saying whether we're just
2295 checking for a frameless function or not.
2297 * core.c (core_open, core_close, core_xfer_memory): Move
2298 section table pointers and bfd* into the target_ops.
2299 (core_open): Allow errors in shared lib reading, etc.
2300 (core_files_info): Describe shared library sections.
2302 * exec.c (exec_open, exec_close, exec_xfer_memory, xfer_memory,
2303 exec_files_info, set_section_command): Move section table
2304 pointers and bfd* into the target_ops.
2305 (add_to_section_table): Add BFD to section table.
2307 * target.c (target_xfer_memory, target_info): Pass target to
2308 xfer_memory and target_info functions.
2311 * gdbcore.h: Move struct section_table.
2312 * target.h: New home of struct section_table.
2314 * solib.c (solib_add): New argument is the target_ops whose
2315 section list is to be added to, if any. Reallocate the
2316 sections in that target to add any that come from shared libs.
2317 (throughout) so_sections renamed to sections.
2318 (solib_xfer_memory): Deleted.
2319 * tm-sunos.h (SOLIB_ADD): Add target argument.
2320 (SOLIB_XFER_MEMORY): Delete.
2322 * core.c, exec.c, inftarg.c, remote-eb.c, remote-nindy.c,
2323 remote-vx.c, remote.c, target.c, target.h: Remove add_syms vector
2324 from target_ops. It's the same on all targets. Add two section
2325 pointers to target_ops.
2327 * stack.c (find_relative_frame): Dump ancient algorithm for
2328 "down", just use handy "next" pointers.
2329 (frame_command): Don't error if there is no stack; let user
2332 * inflow.c (new_tty_prefork, new_tty): New prefork routine
2333 modifies static state in the parent process; new_tty itself
2334 runs in the child and modifies the child's file descriptors
2335 to match the saved static state.
2336 * infrun.c (child_create_inferior): Call new_tty_prefork,
2339 * infptrace.c (child_xfer_memory): Add ignored target arg.
2340 * remote-eb.c (eb_xfer_inferior_memory): ''
2341 * remote-nindy.c (nindy_xfer_inferior_memory): ''
2342 * remote-vx.c (vx_xfer_memory): ''
2343 * remote.c (remote_xfer_memory): ''. Rename from
2344 remote_xfer_inferior_memory.
2346 * main.c (main): Only try to attach "corefile" argument if
2347 it starts with a digit.
2349 * symfile.c (symbol_reloading): New "set/show" variable.
2350 (symbol_file_add): Shorten message about symbol reading.
2351 (add_symbol_file_command): Merge with add_syms_addr_command,
2352 since this should work on all targets now.
2353 (stop_whining): Default to zero, to shut up complaints
2354 about bad symbol tables on many systems.
2355 (free_named_symtabs): Just exit unless symbol_reloading.
2357 * xm-sun3os4.h, xm-sun4os4.h: Define BROKEN_LARGE_ALLOCA,
2358 and add comment explaining shared library screw.
2360 * source.c: #if defined => #ifdef.
2362 Thu Aug 8 12:23:19 1991 John Gilmore (gnu at cygint.cygnus.com)
2364 * doc/gdbint.texinfo: Improve doc on porting to new OS's.
2366 Tue Aug 6 17:16:15 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
2368 * doc/rdl-apps.texinfo: provide default readline-appendix finder
2369 (doc/Makefile knows how to make one for local config)
2371 * Makefile.in: use doc/Makefile for doc targets
2373 * doc/Makefile: GDB documentation now has its own Makefile
2374 doc/refcard.tex: renamed from "gdbrc.tex"
2375 doc/.Sanitize: add Makefile; recognize renamed refcard.tex
2376 doc/gdbint.texinfo: add markup in "Cleanups" chapter
2379 Fri Aug 2 00:13:06 1991 John Gilmore (gnu at cygint.cygnus.com)
2381 * values.c (baseclass_addr): When reading target memory, use the
2382 length of the basetype, not the upper type. We've only malloc'd
2383 enough space for the basetype, leading to errors in free().
2385 * expprint.c (print_subexp): Print UNOP_MEMVAL of an OP_LONG that
2386 ends up as a function specially, since we know the actual type of
2387 the pointed-to address. This (somewhat) fixes display of
2388 expressions that include misc_function_vector names. Try `cond 1
2389 !strcmp("a","b")' then `i b'.
2391 * infrun.c: Move DO_DEFERRED_STORES from proceed() to resume().
2392 The child can be proceeded from inside wait_for_inferior in
2393 evaluating breakpoint conditions, and DO_DEFERRED_STORES was
2394 getting skipped in that case.
2396 * expprint.c (print_subexp): Use filtered output, since the
2397 subroutines we call use it, otherwise the output is horribly
2398 mangled, since output of wrappable stuff comes out late.
2400 * Makefile.in: Bump VERSION to 3.98.1
2402 * infrun.c (child_create_process): Use execlp to find the
2403 shell to exec our target program. This requires some fiddling
2404 with `environ' since there is no execlpe().
2406 Thu Aug 1 15:35:17 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
2408 * Makefile.in, doc/gdbrc.tex, doc/rc-* (new files):
2409 Minor rearrangement of refcard permits two new make targets--
2410 gdbrc.dvi DVI output for refcard, using CM fonts
2411 gdbrc.ps PostScript refcard, using PS fonts
2413 Wed Jul 31 16:46:21 1991 John Gilmore (gnu at cygint.cygnus.com)
2417 * TODO, Projects, WHATS.NEW, README: Update for gdb-3.98.
2418 * Makefile.in (gdb-all.texinfo): Avoid touching file if M4 dies.
2420 Wed Jul 31 16:35:58 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
2422 * doc/gdb.texinfo: last changes for release.
2423 Minor typo and formatting fixes; incorporated most fixes remaining from
2424 filed mail commenting on earlier drafts.
2426 Added warnings: pipes don't work in run command;
2427 conditions are converse of assertions;
2428 step over fn without debug info goes to next fn;
2429 vars may have "wrong" values near fn entrance, exit
2431 Added example from Kingston on printing repeated nonadjacent values
2433 Added explicit mention that in Emacs gdb mode C-c and C-z are like
2434 shell mode for signals
2436 Renamed "Stepping and Continuing" to "Continuing and Stepping" so it
2437 doesn't sound so much like its parent "Stopping and Continuing"; also
2438 moved entries on continue to top of section, so they don't get lost.
2440 Improved installation directions in appendix, added manual formatting
2443 Tue Jul 30 17:26:39 1991 John Gilmore (gnu at cygint.cygnus.com)
2445 * configure.in: Remove xm.h and tm.h even if we aren't linking
2446 new ones, so "./configure sun4; ./configure none" does the right
2447 thing. Assume that alldeps.mak and depend are already built in
2448 srcdir, and avoid running "make" (particularly "make depend",
2449 which involves "gcc") from inside configure. Build Makefile
2450 directly rather than building Makefile.conf first.
2451 * configure: Regenerate with above changes.
2452 * Makefile.in: Use $(BISON) to find bison. Roll VERSION
2453 to 3.98. Revise gdb.tar.Z procedure to produce a file
2454 called gdb-$(VERSION).tar.Z but which unpacks into a
2455 directory called "gdb". Move non-source files out of
2456 $(SFILES_SUBDIR). Pretty up alldeps.mak with comments.
2457 (depend): Don't try to do "gcc expread.y".
2458 (expread.o): Update dependencies by hand.
2460 Mon Jul 29 15:21:09 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
2463 Fixed a variety of small typos that prevented info from formatting
2464 cleanly; altered too-long heading for GPL Appendix, as discussed
2465 w/RMS; Changed date on cover to July 91.
2467 Fri Jul 26 13:20:02 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
2470 (1) Applied some fixes due to comments from Larry Breed (easier ones
2471 through chapsec 5.2)
2472 (2) Eliminated use of @footnote---had my doubts about it anyways, and
2473 it's broken in latest texinfo
2474 (3) Introduced *some* use of [] for optional arguments, where
2475 explanation is not simpler by listing cmd w arg and cmd w/out arg
2476 separately. Still not using @deffn.
2477 (4) Dropped in GPL-2. NOTE: one of GPL-2 or texinfo is broken; a
2478 couple of headings are too long. Need patches to texinfo or revision
2481 * Partial update to README (which still needs work for this
2482 release!): (1) use of configure corrected for new script,
2483 (2) "make gdb.dvi" and "make gdb.info" mentioned.
2485 Wed Jul 24 06:44:02 1991 John Gilmore (gnu at cygint.cygnus.com)
2487 * symtab.c (lookup_symbol): Don't complain right off about
2488 no debug symbols; use the misc function vector first.
2489 (list_symbols): Use misc function vector to find symbols
2490 that don't have debug info, and print them.
2491 (find_pc_symtab): Temporarily avoid fatal() when psymtab
2492 PC range doesn't match symtab PC range, as it does on the
2493 MIPS because our symtab reading isn't perfect.
2495 * dbxread.c (dbx_symfile_read): Make warning about
2496 "no debug symbols" slightly nicer.
2498 * source.c (select_source_symtab): If "main" symbol exists,
2499 but decode_line_spec can't find line info, don't just return
2500 a zero; try other source symtabs or give an error.
2502 * mipsread.c (parse_partial_symbols): Sort the psymtabs by
2503 their low addresses first, then rip through fixing high addrs.
2505 * ns32k-opcode.h (sfsr): Bugfix from Rune Nerg}rd,
2506 <runene@ifi.uio.no>.
2507 (NS32K_SVC_IMMED_OPERANDS): Reverse the #ifndef.
2509 Tue Jul 23 18:52:43 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
2511 * Minor, mostly mechanical, cleanup of doc subdir for clean
2512 makeinfo'ing and TeXing; also ensured gdb-all.texinfo (post-m4)
2513 and gdb.info (post- texinfo2 makeinfo) generated for distribution.
2515 Sun Jul 21 03:54:52 1991 John Gilmore (gnu at cygint.cygnus.com)
2517 Mostly MIPS and general symbol-reading fixups.
2519 * doc/gdbint.texinfo: Add documentation on symbol-reading
2522 * mipsread.c: Remove kludges around #include "ecoff.h".
2523 Remove redefinitions of a_magic, etc, no longer used.
2524 (parse_symbol, ): Convert "Internal:" printfs to complain()ts.
2525 Fix global overview comments to match symfile.c protocol.
2526 (mipscoff_new_init): Eliminate cur_hdr if we have one.
2527 (mipscoff_symfile_read): Eliminate unused code. Avoid
2528 sorting all the symtabs, when all we have read here is psymtabs.
2529 The symtabs are sorted as they are created anyway. Tell
2530 condense_misc_bunches whether we're mainline.
2531 (psymtab_to_symtab_1): Pass filename when recursing, to make
2532 stack trace more informative.
2533 (parse_partial_symbols): Assume cur_hdr as argument.
2534 (read_mips_symtab): Don't clobber cur_hdr, so it can be freed.
2535 Pass cur_hdr implicitly to parse_partial_symbols. Avoid checking
2536 the TYPE_NAME of char *, since that's done in symfile.c.
2537 (free_numargs, parse_symbol, add_symbol, add_block,
2538 shrink_linetable): Declare these fns void.
2539 (upgrade_type): Convert tree of if's to switch. Clean up
2540 bogus "off == 0" handling with a complaint. Avoid setting
2541 field bitpos and bitsize of array with lower and upper bounds.
2542 Check specified bitsize of elements against their actual type's
2543 bitsize, and complain if different. Complain about unknown
2545 (parse_fdr): Don't assume sizeof(char *) == sizeof (struct *).
2546 (psymtab_to_symtab_1): Print names of subsidiary files that
2547 are being read in. FIXME, we read far too many files. This code
2548 is not the problem, the problem is in parse_fdr where the psymtabs
2550 (cross_ref): Result should indicate that we used one aux entry
2551 normally, or two if we encountered a "next" entry. This used
2552 to leave the caller pointing at the wrong aux entry.
2553 (add_symbol): If overflowed cur_block, reallocate it larger,
2554 chase all pointers to it, and complain(), rather than clobber memory.
2555 (shrink_block): Use xrealloc rather than xmalloc-and-copy.
2556 (new_field): Only allocate one field initially, not two.
2557 Pull ++ out of macro argument. Simplify.
2558 (_initialize_mipsread): Avoid initialization of importd
2559 global_psymbols and static_psymbols.
2561 * symfile.c (psymtab_to_symtab): Depend on XXX_psymtab_to_symtab
2562 to properly set pst->symtab; avoid searching for it.
2563 (symfile_fns): Improve comments, add a FIXME.
2564 * dbxread.c: Update comments to reflect symfile protocol.
2565 (read_ofile_symtab, end_symtab): Return the symtab.
2566 (psymtab_to_symtab_1): Set pst->symtab.
2568 * coffread.c (coff_symfile_read): tell condense_misc_bunches
2569 whether we're mainline.
2571 * symfile.h (sym_fns): Remove unused sym_discard member.
2572 * coffread.c, mipsread.c, dbxread.c: Remove XXX_symfile_discard.
2574 * mtrace.c (mtrace): Take effect if mallwatch is set, even if
2575 the environment variable is not.
2576 * infcmd.c (finish_command): Use filtered printfs.
2577 * cplus-dem.c: Add struct tags to a few unnamed structs.
2578 * valops.c (value_coerce_array): Improve comments.
2579 * valprint.c (type_print_varspec_suffix): Print array size only
2580 if greater than zero.
2581 * m88k-tdep.c: Shift some lines left by one space, that had
2582 apparently been trashed at some point.
2583 * TODO: More things to do, a few got done.
2585 Thu Jul 18 22:46:05 1991 John Gilmore (gnu at cygint.cygnus.com)
2587 * symtab.h (LOC_EXTERNAL): Eliminate in favor of LOC_STATIC.
2588 (ldsymoff, ldsymlen, globals_offset, statics_offset): Improve
2590 * dbxread.c (read_dbx_symtab): LOC_EXTERNAL -> LOC_STATIC.
2591 * expread.y, findvar.c, symmisc.c: Ditto.
2592 * printcmd.c (address_info): Update printed forms of LOC_
2593 symbols. Elim LOC_EXTERNAL.
2594 (print_frame_args): Keep track of param stack offsets before
2595 re-looking up to find the local register param is kept in.
2597 * mipsread.c: Use <symconst.h> and <sym.h> rather than <syms.h>.
2598 Further integration of mipsread into gdb. Eliminate unused
2599 routines, duplicate declarations. Handle static symbols in
2600 psymtabs as well as external symbols. When reading symtabs,
2601 insert symbols into the correct block (global, static, or a local
2603 (read_mips_symtab, parse_partial_symbols): Don't pass useless
2605 (mipscoff_symfile_read): Don't call select_source_symtab.
2606 (parse_symbol): Use SYMBOL_VALUE_ADDRESS where appropriate,
2607 rather than SYMBOL_VALUE.
2608 (parse_external): Comment clobbering of top_stack.
2609 (parse_partial_symbols): Update comments. Allocate and parse
2610 static symbols as well as external symbols. FIXME, enum values
2611 are not handled in this pass, but should be. Inline new_psymbol.
2612 Use SYMBOL_VALUE_ADDRESS.
2613 (psymtab_to_symtab_1): Read symbols into global static block
2614 by default (until enter some function's local block context).
2615 (sort_blocks): Clean up STATIC_BLOCK as well as GLOBAL_BLOCK.
2616 (destroy_all_symtabs, new_psymbol): Eliminate, unused.
2618 * source.c (select_source_symtab): Select a source symtab
2619 from either the symtabs or, failing that, the psymtabs.
2620 (list_command): Update error message.
2621 (forward_search_command, reverse_search_command): Use getc, not
2622 fgetc, for speed. FIXME, add comment about buffers that die if
2623 overrun by long line.
2625 * values.c (unpack_field_as_long, modify_field): Avoid shifting
2626 by an entire word, which is not portable, if we have a 32-bit
2627 field. (Code in dbxread.c already turns such bitfields, if
2628 aligned, into ordinary ints, but fixing this will help for other
2629 symbol formats and for future changes.)
2630 * core.c (core_open): Handle ANSI const brain death.
2631 * utils.c (vprintf): Fix varargs typo.
2633 Sun Jul 14 00:42:53 1991 John Gilmore (gnu at cygint.cygnus.com)
2635 * findvar.c (find_var_value): Handle &function better.
2636 * TODO: Document work needed on &fn and &array.
2637 * printcmd.c (print_address_symbolic): New arg is the prefix
2638 to print if a name is printed.
2639 (print_address_demangle): Honor "set print address" now.
2640 Use new arg above to improve spacing of output.
2641 * valprint.c (val_print): When printing function pointers,
2642 print symbolic form too.
2643 * breakpoint.c (breakpoint_1): Use new print_address_symbolic.
2645 Mon Jul 8 19:02:46 1991 John Gilmore (gnu at cygint.cygnus.com)
2647 * core.c (memory_error): Reword error msg to mislead less.
2649 * mips-pinsn.c (print_insn_arg 'd'): Print $ with reg name.
2651 * mipsread.c (read_mips_symtab, read_the_mips_symtab,
2652 parse_partial_symbols): Use newer BFD internals (external_filehdr
2653 and external_aouthdr), byte-swap the fields that we care about
2654 before using them, and make the file header data local to
2655 read_the_mips_symtab rather than global.
2657 Sat Jul 6 01:34:15 1991 John Gilmore (gnu at cygint.cygnus.com)
2659 * ns32k-opcode.h (movmw, movmd): Fix opcodes. Bug fix
2660 from Rune Nerg}rd <runene@ifi.uio.no> on 5 Jul 1991.
2662 * main.c (command_line_input): Flush stdout and stderr
2663 before every call to readline. This reportedly fixes a bug
2664 that comes up in Sys V running emacs-gdb and/or xxgdb,
2665 when stdin/out are pipes or sockets.
2667 Thu Jul 4 14:47:06 1991 John Gilmore (gnu at cygint.cygnus.com)
2669 * configure.in, Makefile.in: Avoid rebuilding "depend" as much.
2670 Avoid declaring Makefile dependencies, because GNU Make stupidly
2671 tries to update it if we do.
2673 * coffread.c: Revise for minor changes to bfd internal coff
2676 * configure: If -template= is given a relative path, make it
2677 absolute before recurring in subdirectories.
2679 * configure, configure.in, Makefile.in: Install "configure" script
2680 as replacement for config.gdb.
2681 * config.gdb, Makefile.dist, Makefile.sdir: Remove
2682 * README: Update for configure, mostly. FIXME.
2684 * Add dec3100 as equivalent to littlemips. Indicate in all host &
2685 target config files that they are for the host. When the lines
2686 get copied into the Makefile, this makes it more obvious what's
2689 Mon Jun 24 23:49:07 1991 John Gilmore (gnu at cygint.cygnus.com)
2691 * sparc-opcode.h (trap opcodes): Avoid leading spaces or
2692 tabs, which end up in the disassembler output inadvertently.
2694 Wed May 29 23:01:03 1991 John Gilmore (gnu at cygint.cygnus.com)
2696 Make it compile cleanly in an ANSI GCC2 environment.
2698 * blockframe.c: <stdio.h>
2699 * cplus-dem.c: free takes a void *, ifdef __STDC__
2700 * dbxread.c (read_huge_number): avoid gcc2 bug hoisting calc of
2702 * defs.h (alloca): Avoid doing anything if alloca already def'd.
2703 * stddef.h, stdlib.h: Remove these files.
2704 * symtab.c: Avoid declaring qsort, close.
2705 * symfile.c: Avoid declaring close.
2706 * utils.c (vprintf): Declare "ap" arg as proper va_alist.
2707 * sparc-tdep.c: Avoid including lots of Sun-host-specific files.
2709 Assorted other changes.
2710 * dbxread.c: include "libaout.h", not "liba.out.h".
2711 * printcmd.c (print_frame_args): Set recurse properly for
2712 indentation of struct and array parameters.
2713 * valops.c (value_cast): Allow cast to void.
2714 * infrun.c (resume): If NO_SINGLE_STEP, call machine dependent
2715 single_step() in a target-independent fashion.
2716 * sparc-tdep.c (single_step): Don't call ptrace ourselves, just
2717 set up to be ready to continue. This makes us target independent.
2718 * infptrace.c (child_resume): Remove call to single_step; now
2719 can single step a SPARC target of any kind.
2721 Wed May 22 18:18:24 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
2723 * Makefile.dist, doc/gdb.texinfo, doc/*-m4.texinfo: split up GDB
2724 docn into separate sections---basically chapters, plus two loose
2725 pieces that can be configured to go in different places. This
2726 allows GNU m4 to preprocess the manual without coredumping.
2728 * Makefile.dist: tell TeX where to find texinfo.
2730 Mon May 20 12:15:04 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
2732 * Makefile.dist, doc/gdb.texinfo: respectively create, and use,
2733 the new target "rdl-apps.texinfo" which captures the Makefile
2734 variable that records where to find the Readline libraries.
2736 Sun May 19 05:36:59 1991 John Gilmore (gnu at cygint.cygnus.com)
2738 * tahoe-pinsn.c: #include "tahoe-opcode.h", not "opcode.h".
2739 * tm-tahoe.h (FIX_CALL_DUMMY): Ignore more parameters.
2740 * defs.h (const, volatile): Only define if not already defined.
2741 * Makefile.dist (gdb.tar.Z): Create doc subdir w/out CVS/RCS crud.
2743 * README: Update for release 3.95.
2744 * config.gdb: Don't create readline dir in subdir builds.
2745 * main.c: Include with "..." form for non-system include files,
2746 so "gcc -MM" for "make depend" works.
2747 Include readline files with "...h" rather than <readline/...h>.
2748 * mipsread.c: Include "ecoff.h" rather than "intel-coff.h".
2750 * coffread.c: Undo minor damage done by Rich Pixley. Use
2751 different internal and external representations of COFF
2752 data structures. Use new BFD routines for swapping them in and
2754 * symfile.c (free_named_symtabs): Avoid freeing file names that
2755 are null or empty. Old i960 tools seem to produce files that
2756 claim to have empty names, causing each successive file read
2757 to blow away the previous one.
2758 * sparc-xdep.c (deferred_stores): Repair minor damage by Rich.
2759 Move deferred_stores to top of file, but don't separate its
2760 #define's from its variable. Add commentary.
2761 * Makefile.dist: Fix Rich damage; undo "configure" changes in
2762 favor of keeping the (working) config.gdb. Move readline
2765 Fri May 17 12:49:56 1991 Per Bothner (via gnu at cygint.cygnus.com)
2767 * dbxread.c (read_struct_type): Try to handle g++ version 1 MI
2769 * infptrace.c (fetch_registers): no result, since now void.
2770 * tconfig/news: target depends on m68k-tdep too.
2772 Fri May 17 14:40:14 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
2774 * Makefile.dist: added readline/inc-*.texinfo to dependencies for
2777 * readline/inc-history.texinfo, readline/inc-readline.texinfo:
2778 applied various small fixes due to or inspired by RMS comments
2780 * doc/gdb.texinfo: finished using all RMS comments, save those for
2781 appendices on readline and cmd history (which are in other source
2784 Thu May 16 18:06:05 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
2786 * doc/gdb.texinfo: (1) Updated w/ref to RMS comments through
2787 chapter 9; (2) documented 'break' command's menu mode for
2788 overloaded names, in response to hgs problem report C++ p-31
2790 Wed May 15 11:02:48 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
2792 * doc/gdb.texinfo: (1) better introductory example; (2) more
2793 consistent use of @code, @samp, @file, @kbd throughout; small
2794 cleanups to first three nodes; (3) new "Contributors" node;
2795 (4) Appendix, Renamed Commands; (5) divert specialized startup
2796 instructions to "Targets" chapter for generic manuals, while
2797 leaving them up front for manuals specific to specialized
2798 environments; (6) apply fixes from RMS comments through chapter 4.
2800 * pretex.m4: modify explanatory text slightly (and redefine
2801 "regexp") to keep GNU m4 from complaining. (It still crashes
2802 later, but one step at a time...)
2804 Wed May 15 10:32:12 1991 John Gilmore (gnu at cygint.cygnus.com)
2806 * readline/readline.c (update_line): Avoid dereferencing a pointer
2807 before comparing it to its bounds. Saber caught this.
2808 (init_terminal_io): Don't set BC from the "pc=" termcap variable,
2809 and only set PC if tgetstr returned non-null. Saber caught this.
2811 Tue May 14 16:29:53 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)
2813 * Makefile.dist: put gdb.dvi stuff (updated to use M4 preprocessor
2814 stuff for config manual) here where it counts; updated
2815 to use new subdir structure (gdb/doc/).
2817 * Makefile: generated from above via
2821 * gdbint.texinfo: added instructions on generating gdb.info* files
2822 locally for release. These are ordinary info
2823 files, formatted from gdb.texinfo (via gdb-all.texinfo, see
2824 Makefile)---but due to use of texinfo 2, can't count on makeinfo
2825 to generate these, so we distribute them already formatted.
2827 * gdb.texinfo: included full Info node and menu crud (as generated
2828 by C-u M-x texinfo-master-menu using the texinfo-2 elisp code).
2830 * Makefile: updated "gdb.dvi" target to use M4 preprocessor;
2831 put in comments-for-future gdb.info target (one day makeinfo will
2834 Tue May 14 13:51:36 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)
2836 * gdb.texinfo: Updated to include new or old undocumented
2837 commands, at least the following (perhaps some others I forgot to
2838 record): info f, info float, info path, info program, info s, info
2839 set, info source, info terminal, info types, info user, set/show
2841 Also covered all recent GDB command renames for v4.
2843 Mon May 13 14:57:46 1991 John Gilmore (gnu at cygint.cygnus.com)
2845 * mipsread.c: Rather than keeping count of how many symtabs
2846 and psymtabs we have, for sorting purposes, count them when
2847 we need to sort. This fixes bug in rereading of symbol tables.
2849 Fri May 10 15:43:33 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)
2851 * infcmd.c: renamed "info path" to "show paths"
2852 * gdbrc.tex: documented above.
2854 Wed May 8 04:51:11 1991 John Gilmore (gnu at cygint.cygnus.com)
2856 * remote.c: Fix comments.
2857 * utils.c (error): Force out any pending wrap output.
2859 Sat May 4 11:11:07 1991 John Gilmore (gnu at cygint.cygnus.com)
2861 * Makefile.dist: Roll VERSION to 3.95.
2862 Fix up "saber_gdb" to work again.
2863 * saber.suppress: Update.
2865 * coffread.c, exec.c, infptrace.c, inftarg.c, remote.c, solib.c,
2866 symtab.h, target.c, target.h: Lint.
2867 * core.c: setup and select frame after reading shared libs,
2868 else reading shared libs will clobber them. Lint.
2869 * utils.c (error): Force out any buffered wrap text.
2871 Fri May 3 22:01:56 1991 John Gilmore (gnu at cygint.cygnus.com)
2873 * remote.c: Remove decls of memory_insert_breakpoint
2874 and memory_remove_breakpoint, no longer used. (Suggestion of
2877 * Makefile.dist: use ${subdir} in paths of BFD and LIBIBERTY,
2878 to make it easier to interface to "configure"'d libraries.
2880 Fri May 3 13:10:01 PDT 1991 Roland Pesch (pesch at fowanton.cygnus.com)
2882 * valprint.c: introduce "set p", "set pr", "show p" and "show pr" as
2883 aliases for set/show print.
2885 Thu May 2 11:22:02 1991 Jim Kingdon (kingdon at cygint.cygnus.com)
2887 * coffread.c (coff_sym_fns) [TDESC]: Make the type be m88kbcs.
2889 * m88k-tdep.c (IEEE_isNAN): New function.
2891 * infrun.c, m88k-tdep.c, m88k-xdep.c: Change
2892 initialize_{tdesc,dcontext} to init_{tdesc,dcontext}.
2894 * infrun.c [TDESC]: Add a bunch of crud.
2896 * xm-88k.h [__GNUC__]: Don't define memset.
2898 * m88k-xdep.c: #if 0 out push_breakpoint.
2900 * tm-88k.h: Define GET_SAVED_REGISTER.
2902 * tm-88k.h: Define DGUX.
2904 * m88k-opcode.h (UEXT, SEXT, MAKE): Put parentheses around arguments.
2906 * m88k-pinsn.c (sprint_address): Declare at top of file.
2908 * m88k-xdep.c: #if 0 out core_file_command.
2910 * values.c ({unpack_,value_as_}pointer): Just call
2911 {unpack_,value_as_}long (for now anyway).
2913 * m88k-tdep.c (get_saved_register): Make get_reg a dc_word_t (*)().
2914 (psr_register): Change return type to dc_word_t.

3386 * inftarg.c (child_open), remote-vx{,.68}.c (vx_proc_open):
3387 New function to give correct error message.
3389 Thu Apr 11 17:19:41 1991 Jim Kingdon (kingdon at cygint.cygnus.com)
3391 * target.h: Add to_doc and target_preopen.
3392 target.c: Add target_preopen and target_command.
3394 (add_target): Call add_cmd and mess with targetlist->doc.
3395 core.c, exec.c, remote-eb.c, remote-nindy.c, remote-vx.c,
3396 remote-vx.68.c, inftarg.c, remote.c: Add doc field to target struct.
3397 Call target_preopen from open routine.
3399 * main.c: Rename editing_info to show_commands.
3400 (_initialize_main): Rename "info editing" to "show commands".
3402 * source.c: Rename directories_info to show_directories.
3403 (_initialize_values): Rename "info directories" to "show directories".
3405 * values.c: Rename convenience_info to show_convenience.
3406 (_initialize_values): Rename "info convenience" to "show convenience".
3408 * copying.awk (_initialize_copying): Rename "info copying" to
3409 "show copying" and "info warranty" to "show warranty".
3410 Rename {copying,warranty}_info to show_{copying,warranty}.
3412 * symfile.c: Rename add_syms_command to add_symbol_file_command.
3413 (_initialize_symfile, add_syms_addr_command):
3414 Rename add-syms to add-symbol-file.
3416 Thu Apr 18 18:08:30 1991 John Gilmore (gnu at cygint.cygnus.com)
3418 * symfile.h (free_named_symtabs): Rename from free_named_symtab.
3419 * symfile.c (clear_symtab_users_once, cashier_psymtab,
3420 free_named_symtabs): Move these routines from symmisc.c.
3421 * symmisc.c (same): same.
3422 (free_symtab): Make non-static.
3423 * symtab.h (free_symtab): Declare as exported void fn now.
3424 * dbxread.c (end_symtab, end_psymtab): Change comments.
3425 (initialize_dbxread): Call dbx_new_init() in case the first
3426 command is add-symbols.
3427 * target.c (dummy_target): Permit add_syms_addr_command.
3429 Sat Apr 13 14:46:07 1991 John Gilmore (gnu at cygint.cygnus.com)
3431 Permit symbols to be superseded when new symbol files have
3432 been read in, particularly for VxWorks.
3434 * dbxread.c (read_dbx_symtab): Allow N_SOL to cleanly take us back
3435 to the main file, as well as to include files. Also, put global
3436 functions into the global psymtab, to make "i fun" work.
3437 (end_psymtab): Free named symtabs and psymtabs for a file, once a
3438 new psymtab for it has been read.
3439 * coffread.c (end_psymtab): Free named symtabs and psymtabs for
3440 a file, once a new symtab has been read for it.
3441 * mipsread.c: FIXME. We need to do the same for MIPS, but it
3442 looks harder to determine the top-level block before it's been
3443 queued to the psymtab list.
3445 * symfile.c (symbol_file_add): Use filtered printing and wrap it.
3446 If we have wiped out any old symbol tables, clean up at end of
3448 (symbol_file_command): Don't reference symfile_fns if it's zero.
3450 * symtab.h (GLOBAL_BLOCK, STATIC_BLOCK, FIRST_LOCAL_BLOCK): New
3451 defines for the blocks of a blockvector that contain global and
3452 file-static symbols and the first of the smaller scope contours.
3453 * symtab.c (lookup_symbol, find_pc_symtab, find_pc_line,
3454 decode_line_1, make_symbol_completion_list): Use the above.
3455 * coffread.c (end_symtab, patch_opaque_types): Ditto.
3456 * dbxread.c (end_symtab): Ditto.
3457 * expread.y (block): Ditto.
3458 * mipsread.c (throughout): Ditto.
3459 * symmisc.c (free_named_symtabs): Ditto.
3461 * symtab.c (list_symbols): Process the first symbol of the
3462 static psymbols list.
3463 (types_info): Restore this function from its untimely #if 0.
3464 It's not perfect, but it is better than nothing.
3465 (_initialize_symtab): Restore "info types".
3467 Thu Apr 11 05:23:19 1991 John Gilmore (gnu at cygint.cygnus.com)
3469 * m68k-stub.c: Remote stub for 680x0's, created from
3470 rem-m68k.shar (which is removed).
3471 * nindy-share/{Makefile,Onindy.c,blout.h,env.h,nindy.c,ttyflush.c}:
3472 Remove RCS log stuff now that we use CVS and it blows our diffs.
3474 Wed Apr 10 14:18:06 1991 John Gilmore (gnu at cygint.cygnus.com)
3476 * symmisc.c (free_named_symtab): Make it work, in its current
3477 kludgy fashion. Change result to indicate if we blew away bkpts.
3478 * dbxread.c (end_symtab): Accumulate result from
3479 free_named_symtab and print warning if we blew user's state.
3480 * symfile.h: free_named_symtab now returns an int.
3482 Mon Apr 8 23:57:43 1991 John Gilmore (gnu at cygint.cygnus.com)
3484 * dbxread.c (dbx_symfile_read): Initialize psymbol list if this
3485 is the first symbol read, even if not mainline.
3486 (dbx_psymtab_to_symtab): symfile might be zero, cope.
3487 * exec.c (exec_ops): Add_syms_addr is valid in our tvec.
3488 (set_section_command): New command ("section xxx yyy" -- should
3489 be renamed to "set section xxx yyy" FIXME) which sets the
3490 base address of a section of the exec file, overriding the
3491 virtual address that BFD reports.
3493 Fri Apr 5 17:14:39 1991 John Gilmore (gnu at cygint.cygnus.com)
3495 * exec.c: Add add_syms_addr_command to exec_ops, so you can
3496 load symbols at any address while examining an exec file.
3498 Thu Apr 4 10:09:35 1991 John Gilmore (gnu at cygint.cygnus.com)
3500 * tm-i386v.h (FLOAT_INFO): Don't define it, since the code
3501 for printing the float info is host-dependent, not
3502 target-dependent. FIXME.
3503 * i386-pinsn.c: Move #includes to top, remove useless ones.
3504 * i386-tdep.c: Don't bother including <.../reg.h> since we
3505 don't use it (and it doesn't exist on host systems).
3507 * ieee-float.c (ieee_extended_to_double): Convert NaN to Inf.
3508 Convert negative numbers properly.
3509 (ieee_test): Make numbers really random; fix format arg.
3511 * infcmd.c (attach_command, detach_command): Don't repeat on CR.
3512 * core.c (core_detach): Unpush core_ops, which might not be on
3513 top. We used to just pop the top, which broke things. Don't
3514 need dont_repeat() any more.
3515 (core_file_command): Psst! Don't repeat it.
3516 * remote-nindy.c (nindy_detach): Don't need dont_repeat() now.
3517 * expprint.c (print_subexp): Avoid switch fallthru on
3518 BINOP_ASSIGN_MODIFY, so we can print += and such.
3519 * frame.h: Fix typo.
3520 * inflow.c (kill_command): After killing inferior, print our
3521 current frame in the core file, if we have one.
3522 (generic_mourn_inferior): When inferior dies, either select
3523 the current frame (in the new target, e.g. core file), or
3524 set both the current and selected frames to NULL.
3526 Changes from Peter Schauer.
3528 * infptrace.c: Avoid <sys/ptrace.h> on USG.
3530 * Make all file names fit in 14 characters (sigh and damn!):
3531 mv hp300hpux-xdep.c hp300ux-xdep.c
3532 mv symmetry-xdep.c symm-xdep.c
3533 mv symmetry-tdep.c symm-tdep.c
3534 mv convex-opcode.h convx-opcode.h
3535 mv tm-vxworks960.h tm-vx960.h
3536 mv tm-vxworks68.h tm-vx68.h
3537 mv Makefile.srcdir Makefile.sdir
3538 mv gdb-int.texinfo gdbint.texinfo
3539 mv remote-sa.m68k.shar rem-m68k.shar
3540 mv remote-multi.shar rem-multi.shar
3541 * Makefile.dist, README, config.gdb, convex-pinsn.c,
3542 tconfig/symmetry, tconfig/vxworks960, tconfig/vxworks68,
3543 xconfig/hp300hpux, xconfig/symmetry: Change names to shorter
3546 * command.c (user_info_1, user_info): New command for listing
3547 the user-defined commands.
3549 Wed Apr 3 15:00:26 1991 John Gilmore (gnu at cygint.cygnus.com)
3551 * dbxread.c (really_free_pendings): Clear file_symbols
3552 and global_symbols after freeing them; otherwise, running
3553 this function twice (if it appears twice on the cleanup
3554 chain), we try to free things twice.
3556 * dbxread.c (read_dbx_symtab): Calculate end_of_text_addr
3557 based on text_addr (the address of text in core), not on addr (the
3558 offset between text in the .o file and in core). This change
3559 is from Peter Schauer.
3561 * main.c: Define ALL_CLEANUPS as a cast of zero.
3562 (return_to_top_level): Use it.
3563 (main): Do all cleanups after each command run as part
3564 of the gdb startup sequence. Also do all cleanups before
3565 entering the command loop, and every time we exit the command
3566 loop and reenter. Before, the cleanups from the startup sequence
3567 were being left undone until the first error!
3568 (command_loop): Rename do_nothing cleanup to command_loop_marker
3569 so we can see it easily when examining the cleanup chain.
3570 (init_signals): Add another do_nothing for signal handling.
3571 (quit_command): Only try to kill target if it has execution.
3572 Problems in the target stack got us into a state where
3573 inferior_pid was nonzero but none of the targets had execution.
3574 In this state you couldn't exit gdb.
3576 * dbxread.c: Two changes from Peter Schauer.
3577 (echo_command): Fflush output after an echo command.
3578 (show_history): Pass all args to cmd_show_list.
3580 * utils.c (init_malloc): Call mtrace to turn on tracing
3581 if the environment variable MALLOC_TRACE is set to a file name.
3582 * mtrace.c: Add source file which provides a log of every malloc,
3583 free, and realloc to a trace file.
3584 * mtrace.awk: Add source file which analyzes the trace file.
3585 * Makefile.dist (GNU_MALLOC, MALLOCSRC): Add mtrace.{c,o,awk}.
3586 (VERSION): Roll to 3.94.3.
3588 * breakpoint.c (breakpoint_1): Add a space to "i watch" output.
3589 (check_duplicates): Don't bother with watchpoints.
3590 (set_raw_breakpoint): Comment about danger of this routine.
3591 (watch_command): Parse and eval all args before calling
3594 * solib.c (find_solib): Avoid error in referencing memory to
3595 see if any more shared libraries have been added. This is
3596 particularly useful if the target has terminated. Bug reported
3599 Changes from Peter Schauer <pesrem@regent.e-technik.tu-muenchen.de>
3600 in bringing up 3.94.2 on the Sun-3.
3602 * Makefile.dist: Include CFLAGS in rule for cplus-dem.o.
3603 * breakpoint.c (enable_breakpoint): Check for valid watchpoint
3604 expression (in scope) before reenabling watchpoint.
3605 * signame.c (init_sigs): Add missing declaration of i, fix
3606 sys_siglist declaration.
3607 * source.c (list_command): Fixed range computation to use
3609 * stack.c (backtrace_command): Do not allow command if target has
3610 no stack, print informative error message.
3611 * target.c (target_command): Do not write into command line
3612 because this fails if the target command is used in a user defined
3613 command. [This change was enhanced by gnu to support any-
3614 unique-prefix matching on target names.]
3615 * valops.c (value_struct_elt): Avoid infinite loop on an
3616 erroneous attempt to print the member of function (try p main.p).
3618 Mon Apr 1 17:05:45 1991 John Gilmore (gnu at cygint.cygnus.com)
3620 * expread.y (name_no_typename): Avoid reduce/reduce errors
3621 caused by ambiguity in handling NAME_OR_INT and NAME_OR_UINT.
3622 Since the GDB parser really doesn't use name_no_typename in a
3623 name-only context, the parser can't tell the diff between
3624 names and numbers here. Avoid allowing a name_no_typename
3625 to be a NAME_OR_*INT to resolve the conflict.
3627 Sun Mar 31 20:12:07 1991 John Gilmore (gnu at cygint.cygnus.com)
3629 Bugfixes from Mark Fox (markf@wrs.com) (test=testField.c):
3631 * valprint.c (val_print_fields): bitfield printing didn't handle
3632 byte order. Indirect through a few more fns to cope.
3634 * values.c (modify_field): also cope with byte order.
3636 Sat Mar 23 10:02:21 1991 John Gilmore (gnu at cygint.cygnus.com)
3638 Cleanup for release 3.94.2:
3640 * Makefile.dist: Pull REMOTE_OBS. Fix saber includes for BFD
3641 include files. Roll version to 3.94.2.
3643 * coffread.c (init_stringtab): Read length into unsigned char
3644 array before swapping; don't assume 32-bit longs.
3646 * target.c (target_info): Don't bother with get_sym_file, just use
3647 the symfile global variable.
3648 * symtab.h, symfile.c (get_sym_file): Delete it.
3650 * dbxread.c (dbx_symfile_init): Don't depend on long == 4 bytes.
3651 (define_symbol): Set symbol line number to 0 if not gcc-compiled.
3652 (read_type): Replace one more error() with complain().
3654 * mipsread.c (parse_partial_symbols): Replace printf with complain.
3656 * i960-tdep.c: Fix copyright attribution.
3658 * config.gdb: Quote all backquotes in doublequotes. You can
3659 quote me on that. BSD 4.4 shell found this one.
3661 * infptrace.c (throughout): The third argument to ptrace is an
3664 * infrun.c (wait_for_inferior): When program has terminated, we
3665 have to call target_terminal_ours before we pop that target off
3666 the stack (e.g. before a call to target_kill or
3667 target_mourn_inferior). This fixes problem where a program
3668 terminates, then GDB stops for (tty output) and you have to type
3669 "fg" to the shell to resume it. FIXME: This code for what to
3670 do after termination really should be in normal_stop instead.
3672 * gdbcore.h (read_memory_check): Change declaration; it changed
3675 * terminal.h: Include <sgtty.h> before <sys/ioctl.h>, since in BSD
3676 4.4 prereleases, this avoids a bug in their sgtty compatability
3678 * remote.c: Use terminal.h rather than hand-rolling the same.
3680 * signame.c, signame.h (psignal): Arg is unsigned, not int.
3681 * utils.c (strsave, strstr): Fix arg types.
3682 * valprint.c (val_print): lint
3684 MIPS symbol table support from Per Bothner:
3686 * symfile.c (symtab_fns): Remove initializer table that needs to
3687 be hacked for each new symbol file format supported.
3688 (add_symtab_fns): New function, chains symbol table
3689 handlers into the global list.
3690 (symfile_init): Search this list.
3691 * symfile.h: Add next pointer, declare add_symtab_fns.
3692 * coffread.c (_initialize_coffread): Call add_symtab_fns.
3693 * dbxread.c (_initialize_dbxread): Call add_symtab_fns.
3695 * mipsread.c (psymtab_to_symtab_1): return void instead of (struct
3696 symbol *). Thus, we no longer need the hack to trash
3697 pst->filename. Good, since that hack confused code in symfile.c!
3699 (reorder_symtabs, destroy_all_symtabs): Removed static
3700 all_symtabs, which was used to qsort symtabs in reorder_symtabs.
3701 Instead, the latter now uses a temporary array (stack-allocated
3702 from an obstack, and then freed).
3704 (parse_symbol): Added a hack to fix up BLOCK_{START,END} if they
3705 haven't been set in the outermost stBlock of a procedure. This was
3706 a problem with f77 binaries on Ultrix 4.?.
3708 (new_symtab, new_symbol, new_type): Continue changing code to use
3709 obstacks more and otherwise conform to dbxread internal style.
3710 Made the free_code of symtabs be free_linetable (as in dbxread)
3711 instead of free_contents. This implies memory leaks when reading
3712 a new symbol table, until the conversion is finished. Did change
3713 (struct symbol) and (struct type) to be allocated on the
3714 symbol_obstack. Blocks and blockvectors are among the things
3717 * mipsread.c (parse_partial_symbols, parse_fdr): It hasn't been
3718 tested much, but it solved one problem (reported by Meissner), and
3719 cleans up some other things. The problem happened when an
3720 included file contains actual code (functions) and not just
3721 definitions. The mips coff is a little inconvenient there, since
3722 it may cause a procedure to be mapped to the wrong psymtab.
3724 * mips-tdep.c (heuristic_proc_desc): Minor cleanup.
3725 * mips-xdep.c (fetch_core_registers): Minor cleanup. FIXME,
3726 this will need work for the new core paradigm.
3728 Opcode patches from the net:
3730 * mips-opcode.h: fix incorrect disassembly of the mfc1, cfc1, and
3731 ctc1 instructions. Also, the cvt.d.w and cvt.s.w instructions were
3732 missing altogether - they are added here. From Bruce Bauman.
3733 * mips-opcode.h: The low mask for C0 instructions was too small.
3734 From Garrett Lau. I modified the fix to check the entire 32-bit
3737 * ns32k-opcode.h: Fix opcodes for deiw and deid. From Bruce
3740 Thu Mar 21 12:56:46 1991 John Gilmore (gnu at cygint.cygnus.com)
3742 Roll in changes from Per Bothner (Tue, 25 Sep 90 11:11:04):
3744 * dbxread.c (read_type): Pointer subtraction (value_sub in
3745 valarith.c) sometimes failed because the types of the
3746 pointers being subtracted were not identical.
3747 These differed because dbxread.c was allocating pointer types
3748 using dbx_alloc_type+smash_to_pointer_type instead of
3749 lookup_pointer_type. I failed to find a justification for the
3750 former, so I changed it to use the latter. Similarly, I
3751 replaced smash_to_function_type by lookup_function_type,
3752 and smash_to_reference_type by lookup_reference_type.
3754 * mipsread.c (parse_symbol, upgrade_type, parse_procedure,
3755 _initialize_mipsread): corresponding changes.
3757 * symtab.c (smash_to_{pointer,reference,function}_type): eliminate.
3759 * source.c (mod_path): Do tilde_expand on each component of the path,
3760 rather than on the (list of) paths as a whole.
3761 (print_source_lines): Set first_line_listed in addition to
3762 current_source_symtab and current_source_line. If the source was
3763 not findable, after a "dir" command to fix the problem,
3764 a "list" would get the wrong lines.
3766 While I was there... (gnu):
3768 * dbxread.c (read_type): Change error to complaint.
3770 Thu Mar 21 12:56:46 1991 John Gilmore (gnu at cygint.cygnus.com)
3772 First attempt at detailed understanding of symbol table memory alloc.
3774 * dbxread.c (dbx_symfile_read): Free our string table if we
3775 aren't the mainline. Free the "info" struct since we're done with
3777 (init_psymbol_list): Free any previously allocated psymbol lists.
3778 (): FIXME: Should realloc-down the psymbol lists when done reading
3779 the main symbol file?
3781 * symmisc.c (free_symtab): Free fullname field too.
3783 * xm-hp300hpux.h (USG): #undef then #define so Makefile can -D.
3784 (REGISTER_ADDR): Make result type unsigned int.
3786 * xconfig/{i386*,hp300hpux,altosgas,altos}: All config files that
3787 define REGEX must also define REGEX1 (its dependency).
3789 Tue Mar 19 21:28:57 1991 John Gilmore (gnu at cygint.cygnus.com)
3791 * tconfig/i960: No longer works, points you at vxworks960 or
3794 * xgdb.c, XGDB-README: Remove file. Users can get the much
3796 * Makefile.dist: Remove all trace of xgdb.
3798 * breakpoint.c (breakpoint_1): Pass demangle arg to
3799 print_address_symbolic.
3800 (clear_breakpoints): Remove unused function.
3801 (breakpoint_re_set_one): Guts of breakpoint_re_set.
3802 (breakpoint_re_set): Use catch_errors to do them all anyway.
3804 * gdb-int.texinfo (Host versus Target): Add section on what is
3805 a "host" feature versus what is a "target" feature.
3807 * infcmd.c (path_command, path_info): Handle the PATH variable
3808 (object search path) as conveniently as the source search path.
3809 * environ.c (set_in_environ): Set some vars in GDB's environment,
3810 in addition to the child's. PATH, G960BASE, G960BIN for starters.
3811 * source.c (mod_path): New function, from guts of
3812 directory_command, modifies a path. Used by path_command.
3813 (directory_command): Call it.
3814 * defs.h (strsave): Declare.
3816 * utils.c (sevenbit_strings): Add new printing option.
3817 (printchar): Use it.
3818 (strsave): Provide this handy helper routine.
3819 (set_width_command): Rename set_screen_width_command.
3820 (_initialize_utils): "set screen-width" => "set width";
3821 "set screen-height" => "set height"; add sevenbit-strings.
3823 * infcmd.c (do_registers_info): Print floating point registers
3824 in raw hex as well as float format, regardless of whether it is
3825 a "virtual" convertible register.
3826 * tm-sparc.h (PRINT_REGISTER_HOOK): Print every pair of float
3827 regs as a double, just in case it's being used that way.
3828 * values.c (unpack_long): Comment on array/function coercion.
3829 (unpack_double): Argument is in target byte order now. For
3830 integer arguments, just call unpack_long and float the result.
3831 * m68k-tdep.c: include defs.h for "const" handling.
3832 * remote-nindy.c: Use ieee-float stuff.
3833 (nindy_fetch_registers): Unpack double regs to host double, then
3835 (nindy_store_registers): Pack extendeds to host double, flip
3836 around by misusing unpack_double, send as target double.
3838 * tm-vxworks68.h (FRAME_CHAIN): Handle current frame pointer of
3839 zero, as when stopped at the first instruction of a process.
3841 * blockframe.c: Fix filename in comment (param.h => tm.h).
3842 * sparc-tdep.c (skip_prologue): More explicit nudging comments.
3843 * tm-68k.h: Fix typos.
3845 Fri Mar 15 01:09:34 1991 John Gilmore (gnu at cygint.cygnus.com)
3847 Changes from a bringup on the DEC Vax under Ultrix 4.0.
3849 * coredep.c (fetch_core_registers): Pass end-address of register
3850 section to register_addr as expected. Don't call supply_register
3851 if we'd just pass it garbage.
3853 * dbxread.c (read_dbx_symtab): Skip N_NSYMS on Ultrix.
3855 * exec.c (xfer_memory): Use boolean xfer_fn result, not int.

3860 * stack.c (print_frame_info): Identify source file & line
3861 even if we can't print it.
3863 * xm-vax.h (MISSING_VPRINTF): No longer missing in Ultrix V4.0.
3865 Sat Mar 9 10:08:20 1991 John Gilmore (gnu at cygint.cygnus.com)
3867 Clean up IEEE floating point support.
3869 * ieee-float.h: New file.

3879 * m68k-tdep.c: Define ext_format_68881.
3880 * sparc-tdep.c: Define ext_format_sparc, though unused.
3881 * Makefile.dist (HFILES): Add ieee-float.h.
3882 * inftarg.c: #include "ieee-float.h" for the REGISTER_CONVERT
3885 Obsolete the "coffstrip" program in favor of using BFD's strip.
3887 * nindy-share/coffstrip.c: Remove file.
3888 * nindy-share/nindy.c (coffstrip): Routine to run bfd_strip.
3889 * Makefile.dist: Remove references to nindy-share/coffstrip.c.
3890 * tconfig/nindy960: Remove reference to coffstrip.o.
3892 * Makefile.dist: Roll version number to 3.94.1 (not yet final).
3894 Wed Mar 6 09:56:45 1991 John Gilmore (gnu at cygint.cygnus.com)
3896 * symfile.h: Add symfile_bfd, common between dbxread and coffread.
3897 * dbxread.c: Remove static symfile_bfd.
3898 * infcmd.c (do_registers_info): Add PRINT_REGISTER_HOOK, though
3900 * inftarg.c (child_detach): Pop the child_ops vector if the
3901 detach is successful.
3902 * remote-nindy.c (nindy_create_inferior): Don't push a new
3903 nindy_ops since nindy uses the same one for execution and memory
3905 * core.c (core_ops): Use child_attach and child_create_inferior
3906 rather than default attach and create_inferior functions.
3908 Handle floating point registers in core files.
3910 * sparc-xdep.c (fetch_core_registers): Rewrite for float support.
3911 * sun3-xdep.c (fetch_core_registers): Rewrite for float support.
3912 This version untested since BFD doesn't yet support sun3 core
3914 * hp300hpux-xdep.c: Rewrite fetch_core_registers to new calling
3915 conventions. Fix comments and style. This version has not
3916 been compiled yet, since we have no HP inhouse.
3917 * core.c (get_core_registers): Look for two sections, ".reg"
3918 and ".reg2", and pass both to fetch_core_registers sequentially.
3920 Revise directory path yet again.
3922 * source.c (forget_cached_source_info): Not static any more.
3923 (init_source_path): New default source path is "$cdir:$cwd".
3924 (dir_command): Handle variable arguments ($cdir, $cwd).
3925 (source_info): Print "Compilation directory" rather than
3926 "Originally compiled in" to remind people of $cdir.
3927 (openp): If the path contains $cwd, use current directory.
3928 (open_source_file): If compilation directory is known, replace
3929 first $cdir in path with the compilation directory.
3930 (print_source_lines): Even if we can't print the lines, set the
3931 current symtab and line for future commands like "info source" or
3932 "breakpoint". Also, error message now contains the file name,
3933 line number, and file access error message.
3934 (_initialize_source): Fix help text to describe changes.
3935 * main.c (cd_command): Forget cached source info when we chdir.
3936 * utils.c (strstr): Add simple implementation.
3938 Tue Mar 5 01:41:40 1991 John Gilmore (gnu at fowanton.cygnus.com)
3940 * coffread.c (read_one_sym, init_linetable, init_stringtab):
3941 Byte-swap COFF symbol tables if necessary when reading them in.
3942 Use complain() to replace error message in one spot. Needs
3943 corresponding change in bfd/coff-code.h to make some symbol
3944 swapping routines non-static.
3946 Mon Mar 4 00:53:40 1991 John Gilmore (gnu at cygint.cygnus.com)
3948 Merge changes from Eirik Fuller, for UTek.

3956 declarations of errno.
3958 * remote-eb.c: Define B19200 and B38400 as EXTA and EXTB.
3960 * remote-vx.c: Include <sys/time.h> for UTek; Sun gets it via
3961 <rpc/rpc.h> and <rpc/types.h>.
3963 Sat Mar 2 15:47:55 1991 John Gilmore (gnu at cygint.cygnus.com)
3965 * i960-tdep.c (examine_prologue): Add new argument limit,
3966 which stops the scan at the end of the prologue, or at the PC.
3967 This fixes a problem where it walks down into the code for the
3968 user's statements if that code looks like function prologues.
3969 Mark Fox and I have been bouncing this code back and forth, making
3970 small changes to it. Callers changed to match.
3972 Tue Feb 26 01:47:07 1991 Cygnus John Gilmore (cygnus at yuba)
3974 Cleanup for gdb-3.94 release final:
3976 * Makefile.dist: Remove remote-vx.c, remote-nindy.c, and all
3977 the .c files from vx-share and nindy-share, from the various
3978 macros, since they are not found via ALLDEPFILES.
3979 (SFILES): Add tm-i960.h.
3980 (alldeps.mak rule): Break out ALLDEPFILES_MAINDIR and
3981 ALLDEPFILES_SUBDIR. List all the nindy and vxworks subdir files
3983 (TAGFILES_MAINDIR): Change ALLDEPFILES to ALLDEPFILES_MAINDIR.
3984 (gdb.tar.Z): Use ALLDEPFILES_SUBDIR as well as SFILES_SUBDIR.

3988 * am29k-tdep.c: Add contribution line.
3989 (examine_prologue): Cache information about function prologues in
3990 the misc-function-vector to avoid lots of references over the
3991 serial line while examining instructions.
3993 * core.c (core_close): New function made from cleanup_core.
3995 * core.c, exec.c, inftarg.c, remote-eb.c, remote-nindy.c,
3996 remote-vx.c, remote.c, target.c, target.h,
3997 Update target_ops vector to add attach, close, and load entries.
3998 Use add_syms_addr_command, not add_file_addr_command, for
3999 add_file. Break out close routine from existing code.
4001 * dbxread.c (really_free_pendings): Don't free pending_blocks;
4002 they are in an obstack.
4003 (read_dbx_symtab): Relocate end_of_text_addr in the psymtab.
4005 (define_symbol): Add symbol type parameter; change callers;
4006 pass type parameter to DBX_PARM_SYMBOL_CLASS macro to allow
4007 it to influence the symbol class on the i960.
4008 (define_symbol): Swap LOC_CONST's into target byte order.
4010 * exec.c (exec_close): New function.
4011 (exec_file_command): Call it.
4013 * findvar.c (read_relative_register_raw_bytes): Doc byte order,
4014 Fix byte order of frame pointer.
4015 (read_var_value): Result of 0 if var's value can't be found,
4016 e.g. missing FRAME_ARGS_ADDRESS. Byte-swap LOC_CONST and
4017 LOC_LABEL values to target order. Add LOC_LOCAL_ARG.
4018 (locate_var_value): Use read_var_value and use its lazy address
4019 as the location of the var's value. Lint.
4021 * i960-pinsn.c (next_insn): Add routine from vxgdb for scanning
4024 * i960-tdep.c (arg_address, i960_frame_find_saved_regs): Remove
4025 obsolete Intel versions in favor of vxgdb versions.
4026 (check_host, byteswap, byteswap_val, reorder_val): Eliminate
4027 code dealing with byte order of values, which Intel did in host byte
4028 order rather than gdb-4's target byte order.
4029 (i960_frame_chain_valid): Move to nindy-tdep.c.
4030 (examine_prologue, skip_prologue, frame_find_saved_regs,
4031 frame_args_address, leafproc_return, saved_pc_after_call,
4032 pop_frame): Add vxgdb versions from Mark Fox.
4033 (examine_prologue, frame_struct_result_address): Add code
4034 to deal with the saved value of G13 (struct return address
4036 (frame_args_address): Modify Mark's version to prefer the
4037 saved value over the current value in the topmost frame.
4038 Cache result in the frame info to avoid performance hair in
4040 (print_fault): Add gdb960 code for printing faults.
4041 (_initialize_i960): Actually call check_host.
4043 * ieee-float.c (ieee_extended_to_double, ieee_double_to_extended):
4044 add stub routines. FIXME, these currently just return zero!
4046 * infcmd.c (program_info): Use PRINT_RANDOM_SIGNAL.
4047 (attach_command): Call target_attach, not target_open, now.
4049 * infrun.c (normal_stop): Make global, not static, for vx_attach.
4050 (child_attach): Rename from child_open.
4051 (wait_for_inferior): Use PRINT_RANDOM_SIGNAL. If stop_pc is zero,
4052 don't confuse it with a zero step_resume_break_address.
4054 * inftarg.c (child_detach): Eliminate inferior_pid test.
4055 (child_files_info): Clean up message a bit.
4056 (child_ops): Use child_attach, not child_open, to attach.
4058 * mem-break.c: #ifdef out the whole file if BREAKPOINT is not
4059 set (e.g. on VxWorks or NINDY). Move read_memory_nobpt from
4060 findvar.c to here, since it depends on the contents of the
4061 shadow_contents of breakpoints, but keep if #if 0 since it is
4064 * nindy-tdep.c: New file, contains nindy_frame_chain_valid, moved
4067 * printcmd.c (address_info): Handle LOC_LOCAL_ARG. Lint.
4068 (ptype_command, display_command): Eliminate have_inferior_p and
4069 have_core_file_p in favor of target_has_stack or
4070 target_has_execution.
4071 (print_frame_args): Handle LOC_LOCAL_ARG. Eliminate duplicate
4072 code for actually finding the values of arguments, though we still
4073 keep track of the maximum stack offset for use in printing unnamed
4074 arguments. Handle missing FRAME_ARGS_ADDRESS.
4076 * remote-nindy.c (i960_print_fault): Move to i960-tdep.c.
4077 (struct nindy_regs): Define registers passed to/from nindy.
4078 (nindy_fetch_registers, nindy_store-registers): Translate between
4079 nindy and GDB formats for the registers.
4080 (dcache_init): Statically allocate the cache, since it was being
4081 allocated by a malloc that was never freed anyway.
4082 (nindy_create_inferior): Error, not core dump, if no exec file.
4083 (nindy_before_main_loop): Use target_load, not target_add_file.
4085 * remote-vx.c (net_load): Specify large timeout for load
4086 requests. Allow user to break out with INTERRUPT.
4087 (net_break): Remove useless code, clean up. Change callers.
4088 (parse-args, skip_white_space, find_white_space): Clean up arg
4089 parsing to cope with quoted strings.
4090 (net_wait, net_quit): Never call error, just return status.
4091 (vx_read_register, vx_write_register): Cleanup status checking.
4092 #ifdef the code based on which CPU we are using (960 or 68k),
4093 FIXME, this should be completely general but it isn't yet.
4094 (vx_xfer_memory, vx_resume): Cleanup status checking.
4095 (vx_run_files_info): Improve message.
4096 (vx_load_command): Renamed from vx_add_file_command. Allow load
4098 (net_ptrace): Remove unused routine.
4099 (vx_wait): Adopt code from vxgdb960 to cope with broken
4100 connections to target machine and prompt to disconnect. Remove
4101 debug printouts. Map some EVENT_'s to SIGnals.
4102 (add_symbol_stub, vx_open): Print names of object files we found,
4103 and "ok" if we read their symbols OK. Clarify output in general.
4104 (vx_attach, vx_detach, vx_kill): Add these commands.
4105 (vx_convert_from_virtual, vx_convert_to_virtual): Simplify.
4106 (vx_run_ops): Turn off all_mem, to avoid spurious msg in the
4107 "info files" output, and create_inferior, since we already have
4110 * stack.c (frame_info): Replace Frame_unknown with 0.
4111 (print_frame_arg_vars): Handle LOC_LOCAL_ARG.
4112 (return_command): Pop until the PC matches as well as the FP,
4113 so it works even if the FP is shared with another function,
4114 as in "frameless" or "leaf" procedures.
4116 * symfile.c (load_command): renamed from add_file_target_command.
4117 (add_syms_addr_command): renamed from add_file_addr_command.
4118 (add_syms_command): Stub to call target_add_syms.
4119 (_initialize_symfile): Change command names and descriptions,
4120 add-file => add-syms, and load from alias to its own command.
4122 * target.c (kill_or_be_killed, maybe_kill_then_attach,
4123 maybe_kill_then_create_inferior): Default for attempts to start
4124 a process, if one is already running, is to ask about killing
4125 it and retry if yes.
4126 (upstack_create_inferior): #if-0 it, strata obsolete it.
4127 (push_target, unpush_target, pop_target): to_close() a target
4128 before unstacking it.
4129 (target_info): Renamed from target_files_info.
4130 (_initialize_targets): Rename "i files" as "i target", accessible
4133 * target.h: Improve comments about the target_ vectored routines.
4135 * tm-i960.h: Remove NINDY-specific stuff to tm-nindy960.h.
4136 Convert commenting style to standard GNU style.
4137 (DBX_PARM_SYMBOL_CLASS): allow LOC_LOCAL_ARG's to be recognized.
4138 (SKIP_PROLOGUE): No longer a no-op.
4139 (SAVED_PC_AFTER_CALL): Now handles leaf procedures.
4140 (*_REGNUM): Sort register numbers.
4141 (REGISTER_BYTES, REGISTER_BYTE, REGISTER_RAW_SIZE,
4142 MAX_REGISTER_RAW_SIZE, REGISTER_CONVERTIBLE,
4143 REGISTER_CONVERT_TO_VIRTUAL, REGISTER_CONVERT_TO_RAW): Float regs
4144 are now 10 byte extendeds, not 8 byte doubles.
4145 (FRAME_CHAIN_VALID): Make this config-dependent, since it differs
4146 for nindy versus vxworks targets. FIXME, this should possibly go
4147 in the target vector.
4148 (EXTRA_FRAME_INFO, INIT_EXTRA_FRAME_INFO): Cache both
4149 frame_saved_regs and arg pointer with each frame.
4150 (FRAMELESS_FUNCTION_INVOCATION): New leafproc support.
4151 (FRAME_ARGS_ADDRESS): Use cached result.
4152 (FRAME_ARGS_ADDRESS_CORRECT): New, avoids g14 guessing.
4153 (FRAME_FIND_SAVED_REGS): Change arg to subsidiary fn.
4154 (PRINT_RAMDON_SIGNAL): Call print_fault.
4155 (POP_FRAME): Now works.
4157 * tm-nindy960.h: Break this off tm-i960.h. NINDY-specific
4158 option parsing and startup; STACK_END_ADDR, FRAME_CHAIN_VALID,
4159 BREAKPOINT, and DECR_PC_AFTER_BREAK are here.
4160 (ADDITIONAL_OPTION_HANDLER): use target_load, not
4163 * tm-vxworks960.h: Break this off tm-i960.h. VxGDB specific
4164 startup; DECR_PC_AFTER_BREAK, and FRAME_CHAIN_VALID are here.
4166 * valarith.c (value_subscripted_rvalue): Avoid handling
4167 floats and doubles specially; it gave alignment errors. Lint.
4169 * valops.c (value_of_variable, value_of_this): Error if unknown
4172 * valprint.c (print_floating): Bcopy rather than pointer-deref,
4173 to avoid alignment problems.
4174 (value_print): Handle unknown value address.
4175 (cplus_val_print): Two args are ignored; remove them. Change caller.
4176 (val_print): Use unpack_long rather than pointer-deref.
4179 (unpack_long, unpack_double): Use bcopy rather than pointer-deref
4180 to avoid alignment problems.
4181 (value_being_returned): Error if return value unknown.
4182 (set_return_value): Add bogosity warning, FIXME. *
4184 * TODO: A woman's work is never done.
4186 * Makefile.dist: Distribute REMOTE_OBS into tconfig files.
4187 Separate INCLUDE_CFLAGS for use with lint. Add LINTFILES.
4188 Add ieee-float.o to OBS.
4189 * tconfig/{nindy960,vxworks68,vxworks960}: Include the desired
4190 REMOTE_OBS remote-interface files in the TDEPFILES and TM_FILE.
4191 * tconfig/i960: FIXME. Half-merge, produce warning if config'd.
4193 Changes to generalize the VxWorks RPC protocol slightly, to handle
4194 i960 as well as 68000.
4196 * vx-share/dbgRpcLib.h (VX_SOURCE_STEP): Add.
4197 * vx-share/reg.h: Produce i960 regs #ifdef I80960
4198 * vx-share/xdr_ptrace.c: Skip FPA registers if 960.
4199 * vx-share/xdr_rdb.h: Add SOURCE_STEP struct and xdr decl.
4200 * vx-share/xdr_rdb.c: Add xdr_SOURCE_STEP routine.
4201 * vx-share/xdr_regs.c: Add xdr_regs, xdr_fp_status, xdr_ext_fp
4202 for i960. Change xdr_vectors to xdr_opaques for 68k registers,
4203 so they will move in target byte order rather than network
4204 byte order (happens to be the same).
4206 Mon Feb 25 03:41:44 1991 John Gilmore (gnu at cygint.cygnus.com)
4208 * tm-convex.h (END_OF_TEXT_DEFAULT): Remove #if 0'd block.
4210 Sun Feb 24 00:55:53 1991 John Gilmore (gnu at cygint.cygnus.com)
4213 Add contribution lines to various files, showing where they
4216 * breakpoint.c (break_insn, check_break_insn_size,
4217 read_memory_nobpt): Remove to mem-break.c.
4219 * xm-*.h, param-no-tm.h, tm-29k.h, valprint.c: Change BYTE_ORDER to
4222 * tm-29k.h (STAB_REG_TO_REGNUM): Warn user if symbol table
4223 entry has bad register number. This change is not
4224 tested in this release, FIXME.
4226 * frame.h: Eliminate Frame_unknown in favor of a simple zero.
4229 * value.h: Force value's contents field to be aligned to hold
4230 at least a double or a long long (if supported). This avoids
4231 doing bcopy's in and out of the contents field.
4233 (step_1): Avoid coredump under obscure circumstances when we
4236 * symtab.h (misc_info): Add field to misc function vector for
4237 any kind of cached information the target code desires. AMD
4238 29000 uses this to avoid repeating examine_function_prologue's.
4240 * coffread.c: Lint. Remove static symfile, read_section_header.
4241 core.c (have_core_file_p): Lint: remove.
4242 expprint.c (print_subexp): Lint.
4243 infptrace.c, valops.c, valprint.c: lint.
4245 Roll in changes from vxgdb-5.0.1:
4247 * symtab.h: Comment byte order of each address class. Add
4248 LOC_LOCAL_ARG for frame-relative args (960).
4249 expread.y: Use LOC_LOCAL_ARG where LOC_ARG is used.
4250 symtab.c, symmisc.c: ditto.
4252 * infrun.c (init_wait_for_inferior): Clear stop_signal.
4254 * remote.c (remote_resume): Error if resume with a signal.
4256 * symfile.c (prim_record_misc_function): Clear misc_info.
4257 (fill_in_vptr_fieldno): Check stub type of arg.
4259 * valops.c (value_cast): Avoid looking up names of types whose
4260 name we don't know, to prevent coredump. Sun CC produces typedef
4261 rtx and the name of *rtx is zero...
4263 Mon Feb 18 21:16:25 1991 John Gilmore (gnu at cygint.cygnus.com)
4265 Roll in changes from final AMD 29000 port (Tiemann).
4267 tconfig/am29k: Add COFF_ENCAPSULATE and TARGET=TARGET_AM29K
4268 for ../include/a.out.encap.h. This might not work now that BFD
4269 is separately compiled. Instead, BFD support for encap will have
4270 to translate machine type 29k into the right COFF_MAGIC.
4272 * infcmd.c: Remove references to inferior_pid that aren't used
4273 in actual ptrace calls; use target_has_execution, etc.
4274 (have_inferior_p): Remove function.
4275 (program_info): Print target info rather than "process number";
4276 avoid gratuitous messages unless from_tty.
4277 (run_stack_dummy, finish_command): Set proceed_to_finish.
4278 infrun.c: Remove inferior_pid refs. Decl & init proceed_to_finish.
4279 main.c: Lint. Lose have_inferior_p().
4280 inferior.h (have_inferior_p): Remove, lint.
4281 (proceed_to_finish): Add flag to ask that all regs be saved
4282 by normal_stop, for the few commands that need it, speeding up
4283 serial I/O. Add comments to stop_registers.
4285 * remote-eb.c: Remove newline from breakpoint message we grep
4286 for. Never time out when running the user program.
4290 Wed Feb 13 15:34:40 1991 John Gilmore (gnu at cygint.cygnus.com)
4292 Roll in changes from vxgdb-5.0.1:
4294 * dbxread.c (read_dbx_symtab): If we encounter a "FORTRAN COMMON"
4295 symbol in its raw form, we are processing an unlinked ".o" file.
4296 See if the target environment has assigned it an address, using
4297 target_lookup_symbol (VxWorks does), and enter it into the symtab
4300 * tm-vxworks.h (FRAME_CHAIN, FRAME_CHAIN_VALID): Override usual
4301 68k versions for a simpler version that assumes zero FP at bottom.
4302 Fixes bug of truncated stack reports.
4304 * target.h (target_lookup_symbol): Define this routine's args
4305 and result, finally.
4307 * target.c (nosymbol): Default routine for target_lookup_symbol.
4308 (target_default): Default lookup_symbol and call_function too.
4309 (files_info): Only print has_all_memory warning if a non-dummy
4312 * remote-vx.c (vx_read_register, vx_convert_to_virtual,
4313 vx_convert_from_virtual): If target does not have floating point,
4314 zero register "values", and avoid doing cross-net conversions.
4315 (vx_lookup_symbol): Rename net_lookup_symbol, add to vectors.
4316 (vx_open): Rearrange code that attaches to target and reads
4317 symbols for all loaded modules, to work if some of the modules
4318 are not accessible. Add symbol_stub() and add_symbol_stub()
4319 as callbacks from catch_errors(). Allow connect attempt to be
4320 interrupted painlessly with ^C (FIXME, there are still some bugs
4321 if the interrupt happens during symbol reading.). Print
4322 final message with puts_filtered, since symbol messages are
4327 * main.c (catch_errors): Only print errstring if non-null.
4328 (command_loop): Avoid an ioctl per command to test ISATTY.
4330 * remote-vx.c (net_load): make static; avoid sophomoric msg.
4331 (vx_xfer_memory): Return correct result!
4332 (vx_files_info): Indicate whether target has float or not.
4333 (vx_lookup_symbol): Complain, not error, if target gone.
4334 (vx_open): Print "Connected" msg before disabling immediate-quit.
4335 [FIXME: lookup_symbol and vx_open changes need testing.]
4337 target.c, remote-eb.c, inftarg.c, am29k-opcode.h, target.h,
4338 tm-29k.h, tmm-vxworks68.h, symfile.c, gdb-int.texinfo: Add
4339 contributor lines and update copyrights to 1991.
4341 Changes from an attempted H-PUX host port:
4343 * infptrace.c (PT_ATTACH, PT_DETACH): Handle HP/UX, which
4344 defines PT_ATTACH and PT_DETACH but not PT_KILL.
4345 * remote-eb.c (eb_open): Misplaced endif kills sysv H/PUX.
4346 * remote-vx.c: include <sys/time.h> for HPUX.
4347 * hp300hpux-xdep.c (fetch_core_registers): Rewrite old
4348 "core_file_command" routine to BFD regime. May not work yet.
4350 Attempted port of "gdb-3.4 Van Jacobson xgdb" to modern gdb.
4352 * xgdb.c: Replace X10 version with some VJ version.
4353 (FIXME: Its copyright assignment is not on record.)
4354 * xgdb.c: Update include files to X11R4 (Xaw crud).
4355 (xgdb_display_source, create_text_widget): fix call to
4356 get_filename_and_charpos. Rewack source window stuff for X11R4
4357 (gleaned from include files, and "nm's" of binary libraries, since
4358 I had no doc available).
4359 (append_selection, append_selection_word): Disable with FIXME
4360 since R4 changed interface here.
4361 (create_buttons): Add back the old set of buttons.
4362 (xgdb_create_window): Fix call to XtInitialize (&argc not argc).
4364 * Makefile.dist (xgdb, xgdb-init.c): Update for X11R4 on Suns.
4365 Roll VERSION to 3.94 (not yet final though).
4367 Sat Feb 9 09:46:25 1991 John Gilmore (gnu at cygint.cygnus.com)
4369 * obstack.h (obstack_ptr_grow, obstack_ptr_grow_fast,
4370 obstack_int_grow, obstack_int_grow_fast): Eliminate
4371 cast on left of assignment, which gives MIPS cc fits and is
4374 * sparc-pinsn.c (print_insn): Eliminate 'set' test, subsumed by
4375 F_ALIAS. Use printf, not fprintf, when not passing a file
4377 (compare_opcodes): Check that identical instructions have
4378 identical opcodes, complain otherwise.
4380 * sparc-opcode.h (st %fsr): Fix opcode "lose" mask. This
4381 was reported by Roland McGrath.
4382 (unimp): Only match if exactly zero instruction. (Roland)
4383 (branches and traps): Generate all variations of these
4384 instructions with macros, based on a single call that defines
4385 each condition name and its binary representation.
4386 (set): Turn on alias bit, to avoid test in sparc-pinsn.c.
4388 * valprint.c (val_print_fields): Take, and use, format parameter.
4389 This means that "p/x struct" again prints the elements in the
4390 desired format. Changed callers.
4392 * stack.c (frame_info): Use filtered output, and indicate wrap
4393 points. Remove kludgy formatting designed to avoid line wrap.
4395 * utils.c (wrap_here): If the line is already full (because
4396 we had printed a long indent or long wrapped string), do an
4397 immediate newline-and-indent.
4399 * m68k-pinsn.c (print_insn_arg): Bugfix from
4400 ntmtv!thompson@ames.arc.nasa.gov (Mike Thompson): 'bkpt #0'
4401 instruction is incorrectly disassembled as bkpt #8.
4403 * dbxread.c (end_psymtab): Bugfix from Peter Schauer
4404 <pesrem@regent.e-technik.tu-muenchen.de>: If you want to set a
4405 breakpoint in a *.y file gdb will say Reading in symbols for *.y...
4406 and then will dump core (sometimes). I traced it back to an
4407 uninitialized symfile_name in psymtab_to_symtab.
4408 (const_vol_complaint): Add quotes to message.
4409 (define_symbol): Only believe line number if gcc_compiled.
4410 Avoid allocating symbol if we will not return it.
4412 Add target strata support so that newly established targets go
4413 into their right place in the target stack (e.g. a new exec file
4414 doesn't wipe out the ability to access the running process).
4416 * target.h, core.c, exec.c, inftarg.c, remote-eb.c,
4417 remote-nindy.c, remote-vx.c, remote.c, target.c: Add to_stratum
4418 and initialize it properly in all the targets.
4420 * target.h: Document strata. Change return type of push_target.
4422 * target.c (nomemory): new function for dummy memory access.
4423 (tcomplain): Rename complain, now also used in symfile.c.
4424 (push_target): Push targets within strata. New return value shows
4425 whether new target is on top of stack or not. Always keep dummy
4427 (target_files_info): Ignore dummy target.
4429 * core.c (core_open): Warn user, and skip accessing file, if the
4430 core target is not the topmost target in the stack.
4431 * remote-nindy.c (nindy_create_inferior): Avoid unpush_target, now
4434 * remote-vx.c: Remove vx_prepare_to_store from vxworks memory
4435 target_ops, it doesn't belong there since we have no regs there.
4436 Change name of target from machine => memory to clarify.
4438 Thu Feb 7 16:32:09 1991 John Gilmore (gnu at spiff.cygnus.com)
4440 * Freeze version 3.93 for release.
4442 * Makefile.dist: Handle vx-share and nindy-share subdirs
4443 properly when building gdb.tar.Z.
4445 * symtab.c: lint; add no_symtab_msg to consolidate the messages
4446 printed in various places, so I could change just one copy.
4448 * dbxread.c, coffread.c: Change references to bfd->iostream
4449 to cast to FILE *, now that BFD avoids needing types defined
4450 in other header files.
4452 Tue Feb 5 21:39:35 1991 John Gilmore (gnu at cygint.cygnus.com)
4454 * command.c, dbxread.c, expprint.c, infcmd.c, infptrace.c,
4455 infrun.c, printcmd.c, remote-nindy.c, source.c, sparc-tdep.c,
4456 sparc-xdep.c, symfile.h, symmisc.c, utils.c, valprint.c: Lint
4457 (actually gcc -Wall).
4459 * dbxread.c: Remove first_global_sym, last_global_sym, since
4460 they are never referenced.
4462 * defs.h (baud_rate): Declare.
4463 main.c: Define it, and add the -b option to set it.
4465 * gdb-int.texinfo: Add text on how to define a new host or target
4466 architecture, prompted by Per Bothner's questions about MIPS
4469 * gdb.texinfo: Document "complaints". Change doc of -q since
4470 gdb no longer prints the copyright and blurb if you specify a file
4471 name to be debugged (just like Emacs). Add doc for Nindy-specific
4472 command line flags for specifying target serial port and such.
4473 Update copyright to 1991.
4475 * gdbcore.h: Remove a large mass of now-useless crud, since BFD
4476 has taken over for us the job of ripping up executable files. The
4477 crud caused Per Bothner's port to not compile.
4479 * infrun.c (normal_stop): Avoid printing "Program exited
4480 normally" if we are in batch mode. This allows a GDB which
4481 executes a program on a target system, to behave like a Unix
4482 command (input from stdin, output to stdout, no extraneous
4485 * main.c (main): Allow additional machine-dependent command line
4486 options to be specified with the ADDITIONAL_OPTIONS,
4487 ADDITIONAL_OPTION_CASES, ADDITIONAL_OPTION_HELP, and
4488 ADDITIONAL_OPTION_HANDLER macros. Also allow machine-dependent
4489 processing to occur just before the main loop with
4490 BEFORE_MAIN_LOOP_HOOK.
4491 (main): If a "core file" argument is specified, and it is not a
4492 core file, try it as a process ID to attach.
4493 (symbol_completion_function): Attempt to cope with
4494 "show screen-" TAB, not very successfully. This needs more work,
4496 (batch_file): New function, returns whether we are reading
4497 commands from an interactive tty on stdin, or from somewhere else.
4498 Called by normal_stop since it doesn't get from_tty passed down
4499 to it like many commands do.
4501 * remote-nindy.c: Handle command line options for nindy
4503 (nindy_before_main_loop): Prompt user for tty name if they
4504 don't specify it before getting to the interactive command loop.
4506 * tm-i960.c: Add ADDITIONAL_OPTIONS, etc, to handle -O, -brk,
4507 and -r command line options. Also add hook before main loop
4508 to make it easy to specify a tty.
4510 * TODO: More things to do, one done.
4512 Mon Feb 4 23:57:39 1991 John Gilmore and Mike Tiemann (at cygint.cygnus.com)
4514 * dbxread.c: Make complaint() calls pass pointer, not struct.
4515 Add complaints about badly formatted C++ type information
4516 (const/volatile indicator, and parse errors resulting in
4517 error_type). Fix C++ virtual member fn comment.
4518 (read_struct_type): Avoid bumping pointer if we got a parse
4519 error; this prevents our walking beyond the end of a string.
4520 Terminate loop on null char as well as semicolon.
4521 (process_one_symbol): Fix the LBRAC fix so that it uses the
4522 last previous SLINE, FUN, or SO record's PC address. C++ debug
4523 symbols did not have SLINE records in a useful order compared
4524 to the LBRAC records.
4525 (define_symbol): Handle "catch" records.
4527 * symtab.c (check_stub_type): Added new complain
4528 `stub_noname_complain' and added a consistency check to
4529 keep the debugger from crashing when finishing from an
4530 exception frame. A real fix will be needed later.
4532 Sat Feb 2 10:43:05 1991 John Gilmore (gnu at cygint.cygnus.com)
4534 * infcmd.c (attach_command): Make global.
4536 * Makefile.dist (REMOTE_OBS): Make these compile by default,
4537 but make them easy to comment out. Perhaps later they should
4538 be enabled by what CPU you configure for? FIXME.
4539 (VERSION): Roll to 3.93.
4540 (pinsn.o): Remove rule for obsolete file.
4541 (dbxread.o,coffread.o,mipsread.o): Use ${srcdir} explicitly.
4543 Run down a problem that manifested by printing the wrong function
4544 name in stack traces of read_ofile_symtab. Turned out that the
4545 problem was the SunOS 4.1.1 (and previous) C compiler outputs
4546 the LBRAC symbol with an address in the *data* segment, which
4547 blew our binary search through the blocks.
4549 * dbxread.c: Use the complain() facility consistently to bitch
4550 about problems in the symbol file we are reading.
4551 (finish_block): Add code to check the nesting of the blocks;
4552 complain and Procrust them to fit if wrong.
4553 (make_blockvector): Check the order of the blocks, complain
4554 [but don't cope] if wrong.
4555 (process_one_symbol): ifndef SUN_FIXED_LBRAC_BUG, check LBRAC
4556 symbols to be sure their PC value is greater than the last SLINE
4557 (line number) symbol we've seen, complaining and adopting the
4558 SLINE PC value if wrong.
4560 * symfile.h (struct complaint, complaint_root, complain,
4561 clear_complaints): Add.
4562 * symfile.c (complain, complaint_root, clear_complaints): Add
4563 facility to deal with non-fatal complaints and to regularize their
4565 (symbol_file_add): Clear complaint counters to allow new complaints.
4566 (initialize_symfile): Add 'set complaints' and 'show complaints'.
4568 * dbxread.c (dbx_symfile_read): Remember the address and size
4569 of the string table for the main symbol file, so we won't read it
4571 (dbx_psymtab_to_symtab): Fix the check for main symbol file,
4572 to avoid reading the string table yet again. Lint.
4573 (throughout): Improve filtered output, including word wrap.
4574 (read_range_type): Improve Bothner's fix to handle other types too.
4576 * utils.c: Improve line wrap implementation. Handle unlimited
4577 width by making chars_per_line unsigned.
4578 (puts_filtered): New, easy, function.
4580 * defs.h (puts_filtered): add.
4582 * mipsread.c (compare_symbols, sort_symtab): Remove these fns,
4583 call the identical sort_symtab_syms() in symfile.c instead.
4585 * expread.y: Suggest the `file' command rather than `symbol-file'.
4587 * command.h (enum var_types): Add zinteger for seroable
4589 * command.c (do_setshow_command): Handle var_zinteger. Restructure
4590 nested if's into a switch.
4592 * breakpoint.c (bpstat_print): If bpstat "print" flag is not set,
4593 we did not stop because of a breakpoint (it must have been for
4594 some other reason, like a "stepi"), so don't print anything.
4596 * symtab.c: Include <sys/types.h> all the time. Now that BFD
4597 doesn't include <sys/types.h>, old SunOS's require it for
4600 Sat Feb 2 10:39:15 1991 Per Bothner (bothner@cs.wisc.edu)
4602 A test port of gdb-3.92.6 to the Sony NEWS.
4605 Don't normally link in remote- or vx stuff.
4606 Some of it doesn't compile, and it wastes space for 99% of the users.
4607 Remove reference to no-longer-used HAVE_VPRINTF.
4608 Fixed BFD_DEP typo to BFD_DIR.
4610 Fix cast in arg to bfd_h_getlong.
4611 Make char *prefix be const.
4612 Fix how certain range types are mapped into builtin unsigned int types.
4614 Remove 2 #includes. They cause errors (on Sony, at least),
4615 and aren't needed (they wern't in earlier versions).
4617 print_address_symbolic should never demangle labels
4618 (since it prints *assembler-level* labels).
4620 [This was superseded by the change to printcmd below.]
4623 Add some "volatile" return types to avoid warnings.
4624 If MISSING_VPRINTF add vprintf function and not just macro
4625 (since vprintf is used in printcmd.c).
4627 Unless __GNUC__, use obstack_grow instead of obstack_ptr_grow.
4628 (The latter isn't grokked by some PCC-based compilers.)
4630 [This change is in abeyance, we prefer to fix obstack_ptr_grow.]
4632 Make chunk size of dont_print_obstack 32*4 instead of default 4096.
4633 * nindy-share/coffstrip.c
4634 Added some forward declarations (otherwise, gcc complains
4635 about implicit extern redefined as static).
4637 Sun Jan 20 02:38:19 1991 John Gilmore (gnu at cygint.cygnus.com)
4639 Changes inspired by Per Bothner:
4640 * printcmd.c (print_address_symbolic): Take additional parameter
4641 specifying whether to demangle.
4642 (print_address): Pass in asm_demangle to control demangling.
4643 (print_address_demangle): New fn, takes explicit arg to control
4645 * utils.c: Add new vars demangle and asm_demangle, and let them
4647 (fputs_demangled): If !demangle, just print the argument.
4648 (fprint_symbol): If !demangle, just print raw symbol.
4649 * valprint.c (val_print): Call print_address_demangle rather than
4650 print_address, to cause demangling to depend on the global
4651 rather than assembler-level demangling setting.
4652 * WHATS.NEW, gdb.texinfo: Document.
4654 * main.c (show_command): Show all settings if no arg.
4655 (initialize_main): Make "info set" the same as naked "show".
4656 * command.c (cmd_show_list): Handle prefix commands in the
4657 list, and print the name of the setting as well as its English
4658 description and value.
4660 Allow gdb functions to specify where a line should wrap if it
4661 exceeds the size of a terminal line. Use it to make the output
4663 * utils.c (set_screen_width_command): New fn, mallocs a buffer
4664 of the right size when screen width changes.
4665 (set_screensize_command, screensize_info): Remove #if 0'd fns.
4666 (wrap_here): New fn, indicates a point in the output where we
4667 should wrap the line rather than just letting it overflow at a
4669 (fputs_filtered): Implement wrapping.
4670 (n_spaces): New fn, returns a pointer to N spaces.
4671 (print_spaces_filtered): Use n_spaces.
4672 * defs.h (n_spaces): Declare.
4673 * stack.c (print_frame_info): Wrap with 4-space indent after
4674 fn name and before filename and line number.
4675 * printcmd.c (print_frame_args): Wrap with 4-space indent
4676 before each argument name is printed.
4677 * valprint.c (value_print): Wrap with no indentation before
4679 (val_print_fields): Wrap with indentation relative to nesting
4680 level before each field name.
4681 (val_print): Wrap with nesting indentation before array elements.
4682 * command.c (do_setshow_command): Avoid extra newlines,
4683 wrap with 4-space indent around values printed, end with period.
4684 * WHATS.NEW, gdb.texinfo, gdb-int.texinfo: Document.
4686 * breakpoint.c (breakpoint_1): Implement addressprint for
4687 "info breakpoints" display. Change file name and line number
4688 format to " at file:nnn" rather than " (file line nnn)".
4689 * gdb.texinfo: Document.
4692 Fri Jan 18 07:21:25 1991 John Gilmore (gnu at cygint.cygnus.com)
4694 Frozen for gdb-3.92.6 release.
4696 README, WHATS.NEW: Update for 3.92.6 release.
4698 tconfig/{altos, i386v, i386v32, m88k, umax}: Eliminate
4699 coffread.o from configs since it is now built by default.
4700 tconfig/{3b1, altosgas, arm, convex, hp300bsd, hp300hpux,
4701 i386v-g, i386v32-g, isi, merlin, news, news1000, np1, pn,
4702 pyramid, symmetry, vax, vxworks68}: Eliminate dbxread.o
4703 from configs since it is now built by default.
4705 Makefile.dist: Update for release 3.92.6. Handle files that
4706 have been moved to ../include, ../getopt, or ../bfd. Add
4707 saber.suppress and tests directory. Add config.status to
4708 the release (it will say "none").
4710 coredep.c: Minor formatting fixes.
4712 These changes were made in early December but only checked in now:
4713 * nindy-share/Onindy.c, nindy-share/coffstrip.c,
4714 nindy-share/nindy.c: lint
4715 * nindy-share/nindy.c (ninStopWhy): Don't byteswap the
4716 register values coming back from the target; we store values
4717 in target byte order everywhere.
4719 Wed Jan 16 19:01:37 1991 John Gilmore (gnu at cygint.cygnus.com)
4721 * am29k-opcode.h, am29k-pinsn.c: Add 29050 opcodes.
4723 * valprint.c (cplus_val_print, val_print_fields): New functions,
4724 which print C++ objects. They conspire to avoid printing a
4725 virtual base class more than once, following all the twists and
4726 turns of C++ virtual base rules.
4727 (val_print): Call the above rather than do it by hand.
4729 * symfile.c (symbol_file_add): Only reset symfile_mtime for main
4730 symbol file, not for added files like shared libs. This really
4731 needs to be generalized to a timestamp per file.
4733 * core.c (cleanup_core): Avoid coredump if no core file.
4735 * config.gdb: Accept -host or -target in place of +host or
4738 * coffread.c (find_linenos): Avoid desupported BFD interface
4739 to line numbers. We still read them manually rather than using
4740 BFD's "generic" features.
4742 * gdbrc.tex, threecol.tex: Add GDB reference card and its
4744 Makefile.dist: Add refcard to OTHERS list for creating tar files.
4746 * Makefile.dist: Eliminate use of $< in explicit targets.
4748 * readline/Makefile: Use $< rather than $*.c, which does not
4749 include the VPATH in GNU Make.
4751 * tconfig/i960-bout, tconfig/i960-coff: These are identical
4752 copies of tconfig/i960, added for global configuration
4753 compatability. All i960 versions can read both coff and b.out.
4755 * tm-88k.h: Fix multiline macro that lacked \'s. Remove
4756 COFF_FORMAT and COFF_CHECK_X_ZEROES since these are now handled
4759 * TODO: Think of more things to do.
4761 Wed Jan 2 19:09:29 1991 John Gilmore (gnu at spiff.cygnus.com)
4763 tconfig/{am29k,i960,sun2*,sun3*,sun4*}: Eliminate config
4764 of sdb versus dbx debug symbols. Add kludge for 68881 80-bit to
4765 64-bit float conversion.
4767 tconfig/sun4, tconfig/sun3, xconfig/sun4, xconfig/sun3: Make
4768 equivalent to sun?os4 so global config works.
4770 Wed Jan 2 18:20:51 1991 John Gilmore (gnu at spiff.cygnus.com)
4772 Fix from Eberhard Mattes <mattes@azu.informatik.uni-stuttgart.de>
4774 * main.c: Only declare linesize once; declare pagesize not at
4775 all, since it is never used.
4776 (main): Clear newly allocated line before it is used.
4778 Fri Dec 28 00:13:42 1990 John Gilmore (gnu at cygint)
4780 Further stabilization for the Intel 960.
4782 * Makefile.dist: Parameterize the location of the "include"
4783 and "bfd" directories, as well as "getopt". Add symfile.c.
4784 Link in both dbxread and coffread. Fix up "make depend" to
4785 rewack the locations of include, bfd, and getopt in its output.
4787 * README: Document moving include files, improve some of
4790 * coffread.c: Move common code out to symfile.c. Change
4791 symbol_file_command style interface to use new *_symfile_init
4792 and *_symfile_read interface under BFD. Use BFD internal
4793 info to locate line table, symbols, etc.
4795 * core.c (core_fetch_registers): Rename to get_core_registers
4796 to avoid confusion with fetch_core_registers.
4797 (register_addr): Move to coredep.c, which is already machine
4798 dependent. This leaves core.c pretty clean of dependencies.
4800 * coredep.c (register_addr): Accept this routine from core.c.
4802 * dbxread.c: Move common code (with coffread.c, etc) into new
4803 symfile.c. Each psymtab now contains a pointer to the
4804 format-dependent function that knows how to read it in. Make
4806 (dbx_psymtab_to_symtab): Renamed from psymtab_to_symtab_2.
4807 (process_one_symbol): Add code to complain about a "compiler bug
4808 we muzzle here", if we actually see it.
4810 * eval.c (evaluate_subexp): Insert missing "break" statements
4811 in code that determines whether a variable is an lvalue in
4812 memory, register, or whatever. I detected this via a compiler
4813 bug in which it *almost* mashed out the whole switch statement.
4815 * gdb-int.texinfo: Add minor sections on configuring gdb for
4816 release, and about the README file.
4818 * infcmd.c (registers_info): Fix formatting somewhat. Still
4819 not as pretty as before, but it handles byte swapping.
4821 * remote-nindy.c: If data cache routines are interrupted while
4822 waiting for the remote end, be sure that any uninitialized cache
4823 blocks are on the free list, not on the valid list!
4825 * symfile.h: Flesh out this header file with all the various
4826 routines and variables that have been merged in from dbxread.c
4827 coffread.c, and symtab.c to symfile.c.
4829 * symfile.c: New file, containing code common to dbxread.c,
4830 coffread.c, and some code from symtab.c. All generic code for
4831 reading symbol files should be in here now.
4832 (unrecord_misc_function): Remove unused function.
4834 * symtab.h: Remove file-reading things to symfile.h.
4836 * symtab.c: Remove file-reading things to symfile.c.
4838 * tm-i960.h: Fix FRAME_CHAIN types; define PRINT_RANDOM_SIGNAL
4839 to decode i960 fault types.
4841 * target.h, remote.c, remote-eb.c, remote-vx.c, remote-nindy.c,
4842 target.c: Change type of the "resume" function from int to void,
4843 since its result was never used.
4845 Sat Dec 22 02:51:40 1990 John Gilmore (gnu at cygint)
4847 * main.c: Replace "stupid" with "caution"; you now "set caution
4850 * printcmd.c (print_scalar_formatted): Fix typo in 'g' format
4852 * infcmd.c (do_registers_info): Call val_print to deal with the
4853 byte order of the registers being printed. FIXME, this makes
4854 the formatting of the output uglier.
4856 * infcmd.c (wait_for_inferior): If PRINT_RANDOM_SIGNAL is
4857 defined, call it for signals the debugger doesn't itself use.
4858 The i960 uses this for more detailed fault information.
4860 * remote.c (remote_open): If arg is null, print help rather than
4863 * sparc-xdep.c (register_valid): Avoid declaring size, since
4864 various modules will think of various sizes depending on the
4865 architecture of their tm-file. FIXME, we need protection against
4866 actually entering one of those modules, which would clobber
4867 storage if not for the target architecture compiled into gdb.
4869 * stack.c (up_command, down_command): Always print the frame
4871 (up_silently_command, down_silently_command): New commands
4874 * i960-pinsn.c (reg), i960-tdep.c: Lint.
4876 * i960-tdep.c (i960_frame_chain_valid): Lookup_symbol now takes
4877 more parameters than it used to.
4879 * findvar.c (registers): Increase slop to 256 bytes, which should
4880 protect us against even most RISC machines with large register
4882 (locate_var_value): Move declaration inside related ifdef.
4884 * remote-nindy.c (): Use TIOCSETN rather than TIOCSETP
4885 throughout, to avoid throwing away buffered input from the board.
4886 (nindy_wait): Supply_register takes addr_of_value, not value.
4887 (i960_print_fault): Renamed from i80960_fault.
4888 (nindy_fetch_registers): Avoid have_regs stuff, just get them.
4889 (nindy_store_registers): Avoid regs_changed stuff, just stuff
4891 (nindy_create_inferior): Don't bother to write PC_REGNUM since
4892 we can set the PC in the call to proceed(). Unpush nindy_ops
4893 before pushing it on top, to avoid message to user. Eliminate
4894 commentary from Unix machines that just misleads here.
4895 (reset_command): Fix error message to suggest target command.
4897 Wed Dec 19 11:03:56 1990 John Gilmore (gnu at cygint)
4899 Release 3.92.5 as frozen.
4901 Stabilize the merged release...with help from lint, Saber C,
4904 Everywhere: Add include files needed to declare return types
4905 of functions called.
4907 * gdb.texinfo: Roland Pesch is documenting gdb, glory be!
4909 * breakpoint.h: Add undeclared breakpoint functions, and some
4910 functions for display handling since I couldn't think of a better
4913 * breakpoint.c (insert_breakpoints): Make code for disabling
4914 shared library bkpts more likely to work. It's used when we
4915 rerun a program and stop before the shared library has been
4917 (breakpoint_cond_eval, bpstat_stop_status): Pass arg as int,
4918 cast from pointer, so it squeezes through catch_errors.
4919 (bpstat_stop_status): Fix logic broken some time ago. We now
4920 always create a bpstat if the stop address matches a breakpoint,
4921 even if we don't stop there -- just like the old code used to do
4922 before I got my fingers into it (sigh).
4923 (breakpoint_1): Print "ignore count" after "stop only if"
4924 condition, since that's how it actually works.
4925 (mention): Handle watchpoints as well as breakpoints.
4926 (watch_command): use set_raw_breakpoint and mention to do most
4927 of the work (and initialize all the fields!). Only pass one
4928 arg to parse_c_expression, since that's all it takes.
4930 * command.c (not_just_help_class_command): Rename arg to args
4931 since we ignore "unused argument" warnings on vars named "args".
4932 inflow.c (child_terminal_info): ditto.
4933 infptrace.c (kill_inferior): ditto
4934 main.c (catch_errors, version_info, quit_command, pwd_command,
4935 source_command, dump_me_command, editing_info,
4936 set_history_size_command, set_history, show_history,
4938 stack.c (locals_info): ditto
4939 target.c (target_files_info): ditto
4940 valprint.c (set_input_radix, set_output_radix): ditto
4942 * core.c: Remove old variables for handling core and exec file
4943 sections (data_start, data_end, stack_start, stack_end,
4944 reg_stack_start, reg_stack_end, reg_stack_offset, text_start,
4945 text_end, exec_data_start, exec_data_end, text_offset,
4946 exec_data_offset, data_offset, stack_offset). They're
4947 superseded the more general build_section_table and
4949 (get_exec_file): Mention the `file' command.
4950 (read_memory_check): Rename to memory_error, and only call it
4951 in the case of an actual error.
4952 (read_memory, write_memory): call memory_error.
4953 (core_fetch_registers): Register section name is ".reg".
4955 coredep.c: Remove a bunch of crud now that all this file does
4956 is pull the registers out of a core file.
4957 (fetch_core_registers): Rewrite to actually work, I hope.
4959 dbxread.c: Use a.out.gnu.h, not system a.out, now.
4960 Replace index() with strchr(). Remove all the pre-BFD macro
4961 definitions for accessing the symbol file.
4962 (struct dbx_symfile_info): Encapsulate the information that
4963 dbx_symfile_init needs to pass to dbx_symfile_read in this
4966 (dbx_new_init, dbx_symfile_init, dbx_symfile_read,
4967 dbx_symfile_discard): Rearrange symbol file reading to divide
4968 the format-specific part from the format-independent part,
4969 leaving the format-independent part such as file name expansion
4970 and opening in symtab.c. This replaces
4971 partial_symbol_file_open and partial_symbol_file_read.
4972 Symbol_file_read, add_file, add_file_target_command,
4973 add_file_addr_command move to symtab.c. Pass an explicit
4974 "mainline" flag for when reading the main symbol table, rather
4975 than relying on the offset address to be zero or nonzero.
4977 (dbx_symfile_read): Don't allow void *'s to be printed as
4979 (SWAP_SYMBOL): Use bfd routines to byte-swap the symbols.
4980 (ADD_PSYMBOL_TO_LIST): Make the "function call rather than
4981 macro" debug version really work.
4982 (read_dbx_symtab): Remove unref'd parameter inclink.
4983 Avoid swapping N_SLINE symbols, for speed.
4984 Merge N_TEXT!N_EXT case with the other external symbol
4985 definitions' case. Add comments.
4986 (start_psymtab): Allocate the symfile name in the psymtab on
4987 the psymbol_obstack, rather than using the caller's storage.
4988 (end_psymtab): Only allocate a dependencies list if there are
4990 (psymtab_to_symtab_2): Use BFD when reopening file to read
4991 its symbols for real.
4992 (read_struct_type): Add FIXME comments where it needs work
4994 (read_huge_number): Add FIXME about overflows.
4995 (read_range_type): Add FIXME about comparing a long to 1<<32.
4997 * coffread.c: Minor changes to move things closer to the new
4998 regime with symtab.c and dbxread.c Major work is still needed
5001 * exec.c (exec_file_command): Remove old variables (see core.c
5003 (xfer_memory): If memory transfer is right at the end of a
5004 section, don't lose.
5006 * findvar.c (get_saved_register): If value is in a real
5007 register, LVAL is lval_register, not lval_memory.
5009 frame.h: Declare print_sel_frame and record_selected_frame.
5011 gdb-int.texinfo: New file, for GDB internals documentation.
5012 Very simple, unformatted doc of cleanups is there for now.
5014 gdbcore.h: Remove obsolete variables that described a.out
5015 section addresses and offsets. (See core.c above.)
5016 Declare fetch_core_registers and registers_fetched.
5018 getopt.c: Declare char *alloca(); even on SPARC.
5020 infcmd.c (run_command): Call target_kill rather than
5022 (step_command, next_command, stepi_command, nexti_command):
5023 Declare from_tty parameter even though we don't use it.
5024 (run_stack_dummy): argument BUFFER is a char array, not
5025 a pointer to REGISTER_TYPE.
5026 (finish_command): using_struct_return needed a value *,
5027 not a struct symbol *.
5029 * infptrace.c (child_xfer_memory): To avoid dependency on
5030 where sections are in memory, try PT_WRITE_D and if that fails,
5031 try PT_WRITE_I. Most Unixes don't care which you use.
5033 * infrun.c (step_resume_break_shadow): Change to array to
5034 match other breakpoint shadow storage.
5035 (clear_proceed_status): Pass address of bpstat to
5036 bpstat_clear, not the bpstat itself.
5037 (child_create_inferior): FIXME comment about if the child
5039 (start_inferior): Remove old function.
5040 (child_open): Use target_kill rather than kill_inferior.
5041 (wait_for_inferior): Ditto.
5042 (insert_step_breakpoint, remote_step_breakpoint): Use
5043 new step_resume_break_shadow.
5045 * inftarg.c (child_wait): If all child processes die,
5046 pretend that the one being waited for exited with signal 42.
5048 * main.c (command_line_input): When scanning for comments,
5049 don't coredump on unclosed quotes.
5050 (quit_command): Use target_kill rther than kill_inferior.
5051 (_initialize_main): Rename class_user from "user" to
5054 * printcmd.c (print_command_1): Initialize "fmt" if no format
5055 is specified by the user.
5056 (print_frame_args): Only add to args_printed if we are
5057 actually fetching args from the stack (avoiding undefined
5059 (_initialize_printcmd): Remove bogus \{ from string.
5061 * remote-eb.c (eb_open): Avoid coredump on no argument.
5063 * remote-nindy.c: Bring out of Intel environment into new
5064 target environment. Remove all conditional compilation on
5065 I80960. Massive hacking throughout.
5066 (nindy_xfer_inferior_memory): New routine stolen from
5068 (nindy_create_inferior): New routine pieced together, probably
5069 not quite working yet.
5070 (nindy_ops): New target_ops struct for nindy.
5072 * remote-vx.c: Use write_memory rather than target_write_memory
5073 to get error checking.
5074 (vx_add_file_command, vx_open): Use symbol_file_add rather than
5076 (vx_create_inferior): Use target_terminal_ours...
5078 * signame.c (_initialize_signame): Always initialize, since
5079 we need the table for things other than psignal.
5081 * solib.c (solib_add): Use symbol_file_add, not add_file.
5082 (solib_address): Return boolean result rather than struct
5083 pointer which nobody else knows the type of.
5085 * sparc-tdep.c, valops.c: Use write_memory rather than
5086 target_write_memory, to get error checking.
5088 * stack.c (locals_info, catch_info, args_info,
5089 get_selected_block, frame_command, up_command): Use
5090 target_has_stack, rather than have_inferior_p or
5093 * sun3-xdep.c (fetch_core_registers): Rewrite for new BFD regime.
5095 * symfile.h: New file, defining the interface between the
5096 generic and object-file-specific symbol reading code.
5098 * symtab.c: Move generic symbol-reading interface to symtab.c,
5099 from dbxread.c, coffread.c, mipsread.c, etc. Add symtab_fns
5100 table to map BFD targets to symbol-reading modules in GDB.
5101 Change index to strchr.
5102 (lookup_struct_elt_type): Use error() rather than hand-made
5103 simulations thereof.
5104 (lookup_partial_symbol): Speedup slightly when length == 0.
5105 (symbol_file_add): New function.
5106 (symbol_file_command): Call it.
5107 (symfile_open, symfile_init): New function.
5108 (add_file_target_command, add_file_addr_command): moved from
5111 * target.c (target_command): use target_kill.
5113 * target.h (target_files_info): Don't declare, never called
5116 * tm-sun2.h, tm-sun3.h (STACK_END_ADDR): Use system include
5117 files to determine stack end address.
5119 * valarith.c (value_x_binop, value_x_unop): Change error message
5120 to be more useful. Pass proper argument to value_struct_elt.
5122 * valops.c (value_assign): FIXME comment that long long
5123 bitfields will break here.
5125 * Makefile.dist: Add symfile.h, remote-nindy.c, remote-eb.c.
5126 Update `make saber_gdb' to work better.
5128 * TODO: A woman's work is never done.
5130 * cplus-dem.c, environ.c, inferior.h, infrun.c, inftarg.c,
5131 main.c, obstack.c, printcmd.c, remote-eb.c, remote-nindy.c,
5132 remote-vx.c, remote.c, solib.c, source.c, sparc-pinsn.c,
5133 sparc-tdep.c, sparc-xdep.c, symmisc.c, symtab.c, symtab.h
5134 target.c, terminal.h, tm-sparc.h, tm-sunos.h, utils.c,
5135 valops.c, valprint.c, exec.c: Lint.
5138 Wed Dec 12 23:44:15 1990 John Gilmore (gnu at cygnus.com)
5140 Continuing Intel 960 port merge of GDB.
5142 * Makefile.dist: Merge i960 "nindy-share" files. Rename
5143 malloc.h to gmalloc.h to avoid name conflicts in /usr/include.
5144 Don't ship gdb.dvi in tar file. Link gdb with init.o, not init.c.
5145 Wack over "make depend" so it handles files in subdirectories
5146 vx-share, nindy-share, bfd, and in the current directory.
5148 * blockframe.c (get_prev_frame_info): Remove fatal error
5149 if stack not defined.
5151 * core.c (core_open, core_detach): New functions that handle
5152 the old "core-file" command as "target core" and "detach" instead.
5153 (core_file_command): Call them.
5154 (core_xfer_memory): Use common routine xfer_memory.
5156 * dbxread.c: Include a.out.gnu.h, not system a.out.h.
5157 dbxread now uses bfd for everything but symbol reading itself.
5158 BFD internals are used to drag out the relevant file offsets.
5159 (partial_symbol_file_open): Change args all around for BFD.
5161 * symtab.c: Rename "value" to "val" everywhere, so we can
5163 (symbol_file_command): New command, moved from dbxread.c
5164 and coffread.c. It uses BFD to read the file, then vectors
5165 based on its type, to dbx or coff symbol readers.
5166 * symtab.h: Extern a few vars for symbol_file_command.
5168 * target.h: Breakpoint takes a char * save area, not a char **.
5170 * valprint.c (val_print): When unpacking bitfields, offset
5171 the address in gdb of the value, if it is declared with a shorter
5172 type. Remove the last "runtime kludge test" of host byte order.
5174 * utils.c: Remove old my_bfd_read routine.
5176 * stack.c (frame_info): Use target_has_stack. Print program counter
5177 register's actual name rather than "pc", since it's called the
5178 "ip" (instruction pointer) on the i960 (sigh).
5180 * target.c (target_command): Add command for selecting a target
5181 type and calling its open routine. This is used for initiating
5182 communication with a particular target, in a generic way.
5184 * tm-i960.h: Update for modern gdb. Remove semicolons from
5185 various macros. Handle reading struct return convention, and
5186 error-out attempts to return structs with the "return" command.
5187 Be sure gdb doesn't think we know how to call functions in the
5190 * i960-tdep.c: Rename FRAME_CHAIN_VALID and FRAME_FIND_SAVED_REGS
5191 to i960_xxx in lower case.
5192 (arg_address): Circumvent errors due to LOC_ARG_BLOCK
5193 not being defined yet.
5195 * remote.c (remote_open): Call start_remote to initialize
5196 wait_for_inferior during open.
5197 (remote_xfer_inferior_memory): Return length written rather
5200 * remote-vx.c (target_command -> vx_open): Use new generic
5202 * remote-eb.c, inftarg.c, exec.c: ditto.
5204 * infrun.c: Fix comments.
5205 (attach_program -> child_open): Use new generic target command.
5206 (wait_for_inferior): Clear saved register values before target_wait,
5207 so target_wait can set some of them if convenient.
5209 * infptrace.c (fetch_inferior_registers, store_inferior_registers):
5210 Return success indicator, not void.
5211 (child_xfer_memory): Avoid fetching initial word if we'll
5212 overwrite it anyway.
5214 * infcmd.c (attach_command): Use new generic target open routine.
5215 (_initialize_infcmd): Update doc on attach and detach commands.
5216 (do_registers_info): Merge in a byte-order problem as a FIXME
5219 * findvar.c (find_saved_register): Avoid problem in current frame.
5220 (read_relative_register): Ditto.
5221 (write_register): Convert byte order on the way out.
5223 * exec.c (file_command): Add.
5224 (add_to_section_table, exec_command): Use new bfd_map_over_sections.
5225 (xfer_memory): Common function between core_xfer_memory and
5227 (exec_xfer_memory): Use it.
5229 * pn-opcode.h: Document that a "PN" is a Gould PowerNode.
5231 * breakpoint.c, breakpoint.h, symtab.h, value.h, frame.h, utils.c,
5232 valops.c, stack.c, target.c, sparc-xdep.c, source.c, printcmd.c,
5233 infcmd.c, i960-pinsn.c, eval.c, defs.h: lint and gcc -Wall.
5235 Sun Dec 2 16:45:06 1990 John Gilmore (gnu at cygnus.com)
5237 Merge Intel 960 port of gdb, continuing...
5239 * dbxread.c (partial_symbol_file_open, partial_symbol_file_read,
5240 symbol_file_command): Pass from_tty arg to hush 'em up.
5242 * coffread.c (symbol_file_command): Avoid output if from_tty != 1.
5243 Add magic numbers for 960 COFF format.
5245 Fri Nov 30 09:18:20 1990 John Gilmore (gnu at cygnus.com)
5247 Merge Intel 960 port of gdb, from Intel "1.2" release.
5249 CHANGE_LOG entries from their port, which was based on
5252 Thu Sep 6 11:02:22 PDT 1990
5253 Remove temp file if download is interrupted.
5255 Wed Aug 1 09:08:33 PDT 1990
5256 Now uses binary protocol to talk to NINDY.
5257 Old hex protocol (NINDY 2.13 and older) supported with -O switch.
5258 Times out after 5 seconds when trying to talk to NINDY.
5260 Tue May 29 12:54:49 PDT 1990
5261 Added variable baud rate (-b switch).
5262 Source code reorganization.
5264 Thu Apr 26 11:09:55 PDT 1990
5265 More cleanup of batch mode; specifically, execute "-s", "-e", and
5266 "-se" switches as soon as they are encountered on the invocation line.
5268 Fri Apr 20 13:47:15 PDT 1990
5271 Thu Apr 19 09:54:28 PDT 1990
5272 Add 'reset' command.
5274 Wed Apr 18 09:48:07 PDT 1990
5275 After opening remote tty, wait for 1 second to go by without input
5276 from it before trying to talk to NINDY (fixes problems with the
5277 Heurikon HK80/V960E).
5279 Mon Apr 4 16:33:05 PDT 1990
5280 Some output was not being suppressed in 'batch' mode.
5282 Thu Mar 22 15:31:11 PST 1990
5283 Ask user if old symbol table should be deleted when new file is
5286 Allow user to run a program downloaded before gdb960 was brought up.
5288 Correct "exec-file" help message for i80960 context.
5290 Correct bug in calculating user space address: could occasionally
5291 corrupt user program.
5293 Make sure to zero low-order bits in rip's because of bug in 960CA
5294 A-step part: could cause operation faults when "next"ing across
5297 Correct bug that made it impossible to get source line numbers for
5298 code loaded at addresses higher than 0x7fffffff.
5300 Wed Jan 10 12:43:22 PST 1990
5301 Open remote tty for exclusive use.
5303 Fri Jan 5 12:14:42 PST 1990
5304 Correct disassembly (CA manual was right after all):
5305 opcode for sysctl is 0x659
5307 Mon Oct 23 12:03:04 PDT 1989
5308 Use G960BASE and G960BIN environment variables to find 'sx' utility.
5310 Mon Oct 16 14:15:09 PDT 1989
5311 "sfr0"-"sfr31" should have been named "sf0"-"sf31"
5313 Mon Oct 2 15:56:31 PDT 1989
5315 Added 960CA disassembly support.
5317 To simplify maintenance:
5318 - eliminated use of symblic links on pinsn.c: use i960-pinsn.c
5320 - eliminated opcode.h: incorporates tables into i960-pinsn.c
5321 - moved 960-specific routines from i960-pinsn.c to i960-md.c
5322 - made disassembly interface identical to that in gdmp960.
5326 Wed Nov 28 21:32:48 1990 John Gilmore (gnu at cygint)
5328 * target.h: Allow targets to stack. Add target_has_memory,
5329 _registers, etc. Restructure memory access and "info files"
5330 to walk the target stack.
5331 * exec.c, core.c, inftarg.c, remote.c, remote-vx.c, remote-eb.c,
5332 target.c: Change tables to match target.h.
5333 * inflow.c (child_mourn_inferior): pop child_ops.
5334 (generic_mourn_inferior): Use new has_stack flag.
5335 * infptrace.c (child_xfer_memory): New memory regime.
5336 * inftarg.c (child_files_info): New "info files" regime.
5337 * remote-eb.c: New memory regime, new info files.
5338 * remote-vx.c: New memory regime, new info files. Now use
5339 separate targets for VxWorks attachment to machine, and
5340 actually running a process under VxWorks, since one has
5341 stack & execution & regs and the other doesn't.
5342 * remote.c: New memory regime, new info files.
5343 * sparc-xdep.c (fetch_core-registers): New memory regime.
5344 * target.c: New routines and support for stacked targets,
5345 new memory regime, new info files regime.
5348 Generalize section handling for an arbitrary number of sections,
5349 including use of the new BFD (binary file) library.
5350 * gdbcore.h: Add struct section_table.
5351 * exec.c (build_section_table): Iterate all sections and
5352 record what gdb needs to know about them.
5353 (exec_command): Use it.
5354 (exec_xfer_memory): Use the table.
5355 (exec_files_info): Print the table.
5356 * core.c (core_file_command, core_xfer_memory, core_files_info):
5358 * source.c (find_source_lines): Use bfd_get_mtime.
5359 * dbxread.c: Quick changes to make it compile with new BFD.
5360 * utils.c (error): Avoid using bfd_error in generic routines.
5362 * core.c (core_fetch_registers): Get from the ".regs" section of
5364 * sparc-xdep.c (fetch_core_registers): Use the .regs info.
5366 * inferior.h (attach_flag): Export.
5367 * infcmd.c (run_command): use new target_create_inferior.
5368 * infrun.c (child_create_inferior): Don't return result.
5369 * Makefile.dist (VERSION): 3.91.4.
5371 Fri Nov 23 28:15:38 1990 John Gilmore (gnu at cygint)
5373 * breakpoint.c (bpstat_num): Handle breakpoints which have
5374 since been deleted, such as temporary breakpoints.
5375 infcmd.c (program_info): ditto.
5377 * core.c (core_file_command): Display the frame where the core
5382 * remote-vx.c (target_command): Merge in target command from
5383 targ-vx.c. A few other cleanups.
5385 * TODO, Projects: Lots more stuff to do...
5387 Fri Nov 23 18:15:38 1990 John Gilmore (gnu at cygint)
5389 Massive changes to wall off the remote-debugging interface
5390 behind a function vector. The port to handle VxWorks targets
5391 is also part of this.
5393 All files: Replace references to renamed functions,
5394 remove references to remote_debugging, remove references to
5395 have_include_file, have_core_file in favor of target_has_stack,
5396 target_has_memory, etc.
5398 * Modularize the breakpoint interface.
5399 breakpoint.h (BREAKPOINT_MAX): New define sets max length of
5400 a breakpoint instruction.
5401 breakpoint.c: struct breakpoint's shadow_contents now sized as
5403 (insert_breakpoints): Vector to target to install breakpoints.
5404 (remove_breakpoints): Vector to target here too.
5405 Remove REMOTE_SA_SPARC kludges and other remote_debugging.
5406 sparc-tdep.c (single_step): Use new breakpoint interface for
5407 the single-step breakpoints.
5408 mem-break.c (memory_insert_breakpoint, memory_remove_breakpoint):
5409 New file, contains routines to insert and remove breakpoints by
5410 reading out the old contents and later replacing them. This is
5411 how ptrace breakpoints work, and many remote systems as well.
5413 * tm-vxworks68.h: New config file, overrides a few things for
5414 Wind River's preferences.
5416 * target.h: New file, for transfer vector used to talk to the
5417 inferior (child, attached, core, exec, remote, etc). All accesses
5418 to the thing being debugged should come through these vectors.
5419 target.c: New file, routines to handle transfer vector.
5420 (various files): Add transfer vectors XXX_ops for the various
5421 targets and pseudo-targets (core files, etc) we support.
5423 * breakpoint.c (bpstat_stop_status): Further explorations of
5424 watchpoints and why things don't work all the time.
5425 (bpstat_alloc): New fn to allocate a bpstat and chain it.
5427 * config.gdb: Only add "source ${srcdir}/.gdbinit" to
5428 the local gdbinit if it doesn't already have it.
5430 * core.c (core_ops): add and install.
5431 Allow core debugging without exec file.
5433 * dbxread.c (free_and_init_header_files): Merge two fns.
5434 (end_symtab): Free named symbol table when a new version comes in.
5435 (read_dbx_symtab): Relocate all kinds of symbols with base
5436 address. First step toward handling different text, data, bss
5438 (add_file_addr_command): Renamed add_file_command.
5439 (add_file_command): Vector to remote handler.
5440 Add "load" as an alias for "add-file" command.
5442 * defs.h: Allow "volatile" to be used in non-ANSI; use it for
5443 non-returning functions.
5445 * exec.c: Add exec_ops, and push it as a target when an exec
5448 * infcmd.c (run_command): Pass executable file name and arg list
5449 separately when starting an inferior. Permit "run" when no exec
5450 file is specified, for VxWorks.
5451 (detach_command): Move to child_detach in inftarg.c.
5453 * inftarg.c: New file. Unix-child-specific routines, and the
5454 child_ops structure.
5456 * inferior.h (registers): Export "registers" as the way for
5457 target dependent register handlers to find gdb's local copy of
5458 the registers. Rename "stop_after_attach" to "stop_soon_quietly"
5459 since it is now used by places that want wait_for_inferior to
5460 handle the grunge but want to see every trap from the inferior.
5462 * inflow.c (create_inferior): Pull out, and merge into infrun.c.
5463 Eliminate remote_debugging hooks in terminal handling.
5465 * infrun.c: Replace start_inferior with child_create_inferior.
5466 Move all the hair of Unix shells and ptrace idiosyncracies into
5467 child_create_inferior, so remote handlers don't have to deal.
5468 Remove running_in_shell. Rename stop_after_attach to
5469 stop_soon_quietly, and use it in a few other places where we want
5470 to just call wait_for_inferior and get control back on the first
5471 trap. trap_expected now never takes a value > 1.
5472 (init_wait_for_inferior): Initialize static vars when a new
5475 main.c (gdbinit): Add new hook for .gdbinit file name, let
5476 it be overridden by config files as GDBINIT_FILENAME.
5477 (DEFAULT_PROMPT): Add new hook for overriding (gdb) prompt.
5478 Both of these are used for VxWorks gdb.
5480 mcheck.c: rename include file "gmalloc.c" to avoid problems
5481 with system include file "malloc.c".
5483 param-no-tm.h: New include file, same as param.h but does not
5484 include the default "tm.h" file. This is used in files where
5485 the target is known, e.g. remote-eb.c or sparc-xdep.c.
5487 param.h: Now just a shell that includes tm.h and param-no-tm.h.
5489 remote-vx.c: New file, VxWorks remote debugging support. Uses
5490 RPC routines that are shared with the target system, in directory
5493 remote.c: Vectorize remote interface.
5495 source.c: Globalize source_path, and make an alias "l" for "list"
5496 since we now have the "load" command.
5498 sparc-xdep.c: Use new param-no-tm.h.
5500 symmisc.c (free_named_symtab): Add new function from Wind River.
5501 However, ifdef it out for now while we think about what it should
5504 tm-sun3.h, xm-sparc.h, xm-sun3.h, xm-symmetry.h: Move
5506 the xm- file, and change its name to CHILD_PREPARE_TO_STORE, since
5507 non-Unix-children handle this with their own code in the target
5510 Makefile.dist: Roll version to 3.92.3. Add vx-share stuff to
5511 source and target lists. Add vx-share to default list of include
5512 directories. Add new files to src and target lists: mem-break,
5513 target, inftarg, remote-eb, remote-vx, targ-vx. Be sure the
5514 ${srcdir} versions of munch and createtags are used.
5516 * valops.c (find_function_addr): Split out of call_function.
5517 (call_function_by_hand): Rename call_function; this function
5518 calls functions in the target by laboriously patching the target
5519 word-by-word with the right stack, args, regs, etc.
5522 Mon Nov 5 17:29:10 1990 John Gilmore (gnu at cygint)
5524 Handle AMD 29000 a bit better.
5526 * remote-eb.c (readchar): Mask received char log to make it readable.
5527 (remote_start): Pass arguments down to executing program.
5528 Make startaddr unsigned.
5529 infrun.c (start_inferior): Accept args, pass them to
5531 infcmd.c (run_command): Pass args down to start_inferior.
5533 * tconfig/am29k-aout, tconfig/am29k-coff: New files specifying
5534 the target object file format.
5535 tm-29k.h: Pay heed to COFF_ENCAPSULATE.
5537 * am29k-pinsn.c (print_insn): Print 0x on hex numbers in disassembly.
5538 am29k-tdep.c (examine_prologue): Better checking of function prefixes.
5540 Sun Oct 7 18:20:45 1990 John Gilmore (gnu at cygint)
5542 * Makefile.dist (VERSION): Roll version to 3.91.9 and freeze.
5543 * TODO: We did a few things, we have more to do though.
5545 * xm-sparc.h (CLEAR_DEFERRED_STORES): Define.
5546 * inflow.c (inferior_died): Clear deferred stores.
5548 * Debug problems with dummy frames and calls to the inferior.
5549 * tm-sparc.h (PUSH_DUMMY_FRAME, POP_FRAME): Move to sparc-tdep.c.
5550 * sparc-tdep.c (do_restore_insn): Simplify.
5551 (sparc_frame_find_saved_regs): Simplify and fix what we find.
5552 (sparc_push_dummy_frame): Simplify and fix what we push.
5553 (sparc_pop_frame): Slightly more hair here, deciding whether
5554 we are restoring a saved PC or returning to a return address in %i7.
5555 * sparc-xdep.c (read_inferior_registers): Debug if valid reg is read.
5557 * utils.c (xmalloc, xrealloc): Return type depends on __STDC__.
5558 * symtab.h (xmalloc): ditto, for obstack_chunk_alloc.
5559 * obstack.h (chunkfun): ditto.
5560 * defs.h (xmalloc, xrealloc): ditto
5562 * utils.c (quit): Grab the terminal from the child if necessary.
5564 * inflow.c (term_status_command): Rename to term_info, change
5567 * sparc-pinsn.c (print_insn): Disassembly prefers real instructions.
5568 (is_delayed_branch): Speed up.
5569 * sparc-opcode.h: Add ALIAS bit to aliases. Fix up opcode tables.
5570 Still missing some float ops, and needs testing.
5572 * Support for input and output radixes other than base 10
5573 * defs.h (input_radix, output_radix): Declare.
5574 * expread.y (yyparse, parse_number): Handle changes of input
5575 radix, and ambiguous names-or-numbers in radixes >10.
5576 * printcmd.c (print_scalar_formatted): Print formatted hex
5577 numbers in varying column widths.
5578 * valprint.c (val_print): Use output_format to print scalar ints.
5579 (set_input_radix, set_output_radix, set_radix): Create.
5580 (set_output_radix): Set output_format from output_radix.
5581 (_initialize_valprint): add `set radix' but leave the others off.
5583 * main.c (execute_command): Let stupid questions be turned off.
5584 (_initialize_main): Handle "set stupidity", etc.
5586 * main.c, inflow.c, inferior.h, frame.h, command.c, defs.h,
5587 sparc-pinsn.c, sparc-xdep.c, value.h, valops.c, values.c: Lint.
5589 Tue Oct 2 11:20:02 1990 John Gilmore (gnu at cygint)
5591 * TODO, Makefile.dist, ChangeLog: Freeze for 3.91.8 release.
5592 bfd stuff is still screwed up, but with some manual work, it
5595 * breakpoint.c (bpstat_do_actions): Start over if a command
5596 proceeds the inferior, since the inferior will have stopped and
5597 will need to have its new stop-actions taken care of.
5599 * dbxread.c (read_struct_type): Expression gives Sun3 4.0.3
5600 compiler fits, simplify it.
5602 * gdb.texinfo (directory command): Doc new dir command.
5603 source.c (directory_command): "dir" now puts things on the front
5604 of the path, moves dups up front, and handles multiple names
5605 on the command line, inserting each one in order. It also
5606 blows away cached line and full_filename info.
5608 * stack.c (backtrace_command): Skip "more stack frames follow"
5611 * Change #ifndef HAVE_VPRINTF to #define MISSING_VPRINTF in
5612 xm-convex.h, xm-hp300bsd.h, xm-isi.h, xm-merlin.h, xm-news.h,
5613 xm-np1.h, xm-pn.h, xm-pyr.h, xm-symmetry.h, xm-umax.h, xm-vax.h.
5614 The only odd one was Gould NP1, which had defined vprintf to
5617 * Merge Ted Goldstein <tedg@Eng.sun.com>'s changes for epoch.
5618 printcmd.c (print_command_1): Pass 'inspect' flag down as a global
5619 variable, inspect_it.
5620 valprint.c (print_string, val_print): Use the global inspect_it
5621 to indicate whether to print in Epoch style or normal style.
5623 Mon Oct 1 23:55:26 1990 John Gilmore (gnu at cygint)
5625 * printcmd.c (call_command): add an alias for the "print" command
5626 which runs expressions and doesn't print the result if void.
5627 (print_command_1): implement it.
5629 * command.c: Remove #if 0'd code. Initialize all the fields
5630 in add_cmd (). Rename do_nothing_command to
5631 not_just_help_class_command, and make it externally visible.
5632 command.h: add user_commands to struct.
5633 * main.c (define_command): Don't overload c->function with a char
5634 string as well as a function pointer.
5636 * eval.c (evaluate_subexp): Reinstall tiemann changes to
5637 calling convention of value_struct_elt () that got dropped in
5640 * tm-sparc.h (FRAME_FIND_SAVED_REGS): move to sparc-xdep.c.
5641 sparc-tdep.c (sparc_frame_find_saved_regs): ditto.
5643 * tm-sparc.h (POP_FRAME): replace some constants with defines.
5645 * sparc-xdep.c (store_inferior_registers): defer stores to regs
5646 until a good time (e.g. when we are about to run the child),
5647 saving ptrace calls.
5648 * infrun.c (proceed): handle DO_DEFERRED_STORES.
5649 * tm-sparc.h: define DO_DEFERRED_STORES.
5651 * sparc-xdep.c (store_inferior_registers): when storing float
5652 registers, don't store stack regs too. When storing the SP,
5653 however, DO store the stack regs too. This fixes a bug in which
5654 the dummy frame is not recognized when a call_function finishes,
5655 because its frame pointer (in the stack regs) was never
5657 (read_inferior_registers): Mark WIM and TBR and FPS and CPS valid
5658 even though we don't know how to read them from an inferior.
5659 valops.c (call_function): Comment about storing SP.
5661 * infrun.c (save_inferior_status): Save away the original bpstat
5662 chain so it can be restored later. Install the copied version for
5663 use by whoever saved the status. It will be blow away by
5664 restore_inferior_status, and the original chain restored. This is
5665 important for people who have pointers into the original.
5667 * breakpoint.c, command.h, copying.awk, dbxread.c, defs.h,
5668 findvar.c, frame.h, obstack.h, obstack.c, inflow.c, value.h,
5669 main.c, printcmd.c, sparc-tdep.c, symtab.c, valprint.c: lint
5672 Fri Sep 28 20:32:46 1990 John Gilmore (gnu at cygnus.com)
5674 * Makefile.dist: Roll version to 3.91.8. Add bfd.h and bfdconfig.h
5675 temporarily to the makefile. Add am29k-opcode.h and WHATS.NEW.
5676 Add stuff.c and kdb-start.c to the OTHERS list for tar files.
5678 Fri Sep 28 19:12:12 1990 John Gilmore (gnu at cygint)
5680 * Merge Mike Tiemann's multiple inheritance changes from Sun.
5681 Store the baseclasses in a type struct starting from array element
5682 0 rather than from the unusual array element 1.
5684 dbxread.c: the above.
5685 (virtual_context): Add
5686 Read new debug information about which virtual function table
5687 a virtual function is from, and store it in fn_field.fcontext.
5689 symtab.h: Add fcontextt. Fix baseclass indices. Typo in
5690 TYPE_FN_FIELD_STATIC_P.
5692 symtab.c: the above.
5693 valops.c: the above. Handle pointer casts of object *'s.
5694 (search_struct_method): Add.
5695 (value_struct_elt): First arg is now a pointer to a value, and is
5698 valprint.c: the above.
5699 values.c (value_virtual_fn_field): Add type arg. Handle
5700 offsetting to the proper object when calling virtual fns.
5702 (baseclass_addr): Add valuep arg.
5704 * README: Document the current state of BFD config (missing).
5705 * TODO, ChangeLog, Makefile.dist: Roll version.
5706 * WHATS.NEW: Add summary of changes since 3.5.
5708 Thu Sep 27 16:23:12 1990 John Gilmore (gnu at cygint)
5710 * dbxread.c (read_struct_type): Clear bit vectors whenever
5712 symtab.c (B_CLRALL): define.
5714 * tm-sparc.h (STORE_RETURN_VALUE): Avoid clobbering types by
5715 using == rather than =. Huh... This fixes the dreaded problem
5716 wherein builtin_type_int becomes TYPE_CODE_FLT.
5718 * core.c (info_files): Show the inferior pid.
5720 * config.gdb: Avoid putting "dir" command into .gdbinit. GDB
5721 already knows how to look in the source directory.
5723 * Remove psymtab hair from many places. Remove duplicated code
5724 for searching symbol tables. Hide psymtabs from most places.
5725 Make it fast to get from a psymtab to its symtab.
5727 blockframe.c (blockvector_for_pc): Remove psymtab hair.
5728 coffread.c (psymtab_to_symtab): Rename to psymtab_to_symtab2.
5729 mipsread.c (psymtab_to_symtab): Rename to psymtab_to_symtab2.
5730 dbxread.c: export psymtab_to_symtab, make it work if called N times.
5731 (psymtab_to_symtab): Rename to psymtab_to_symtab2. Initialize
5732 new symtab completely. New psymtabs get symtab pointer
5733 initialized to zero. Remove MI warning printf.
5734 symtab.h: Comments. Add psymtab to symtab pointer.
5735 (PSYMTAB_TO_SYMTAB): New macro.
5736 symtab.c: use PSYMTAB_TO_SYMTAB. Add psymtab_to_symtab and export it.
5737 source.c: use PSYMTAB_TO_SYMTAB. Remove symtab version and
5739 stack.c (backtrace_command): Avoid pre-pass to read symbols, if
5741 (print_frame_info): Avoid special-casing symbols that have not yet
5744 * source.c (open_source_file): Quick path if we have already
5745 located the source file by its full name.
5747 * symtab.c (lookup_symbol): Use find_pc_symtab rather than
5748 find_pc_psymtab. When a name is found in the misc function
5749 vector, search the symbol table for its mangled name, not the
5750 name that the user typed.
5752 * bfd.h: Fix missing comment terminators, make #endifs match.
5754 * valarith.c (value_less): Handle unsigned int comparisons.
5755 Add FIXME about pointer compares, which assume host and target
5756 pointers are the same.
5758 * command.c (do_nothing_command): lint
5759 dbxread.c: lint. Remove sort_syms. Document C++ visibility info,
5760 fix comments on debug symbol format for visibility. Actually set
5761 visibility of symbols.
5762 main.c (echo_command): lint; use <readline/history.h>.
5763 tm-sparc.h (FRAME_FIND_SAVED_REGS): lint
5764 obstack.h (_obstack_blank): Rearrange pointer math to avoid
5765 pointing past end of allocated memory; saber complains.
5766 obstack.h: Declare the external functions that we use.
5767 valarith.h: use <string.h>
5768 solib.c (solib_add): lint.
5770 Fri Sep 21 17:05:19 1990 John Gilmore (gnu at cygint)
5772 * main.c (initialize_main): Default info_verbose to off, now that
5773 symbol reading is fast.
5774 (quit_command): Avoid clobbering exec_bfd while quitting.
5776 * Initial BFD (binary file diddling library) merger:
5777 coffread.c: Change AOUTHDR to struct exe_hdr.
5779 core.c: initialize initialized data at compile time.
5780 (core_file_command): Move from coredep.c, convert to bfd.
5781 (xfer_core_file): Convert to bfd.
5782 exec.c (exec_file_command): use bfd routines.
5784 mips-tdep.c: Remove exec_file_command and friends.
5787 * coredep.c: (fetch_core_registers) Convert core_file_command to
5788 fetch_core_registers.
5789 mips-xdep.c, sparc-xdep.c, sun3-xdep.c: ditto.
5791 * utils.c: (error): Bogus crap, FIXME, to print bfd errors.
5792 (my_bfd_read): More bogosity, which I don't think we call.
5793 (program_name): Remove this atrocity asap!
5795 Wed Sep 19 13:36:41 1990 John Gilmore (gnu at cygint)
5798 values.c: allocate_repeat_value was not clearing the
5799 optimized_out field.
5800 (value_static_field): minor stylistic fix (wrong macro was used).
5801 valops.c (value_struct_elt_for_address): didn't work for C++
5804 * signame.c (_initialize_signame): Initialize signal names once.
5806 * breakpoint.h, command.c, copying.awk, defs.h, environ.c,
5807 exec.c, frame.h, infcmd.c, inferior.h, main.c, munch, sun3-xdep.c,
5808 symtab.h, tm-29k.h, valprint.c, value.h, values.c: Lint.
5810 * remote-eb.c: Support user-settable baud rates on the serial port.
5812 * tm-sun3.h (PREPARE_TO_STORE): fix typo.
5814 Fri Sep 14 13:28:29 1990 John Gilmore (gnu at cygint)
5816 * tconfig/sun3os4: Remove warning about native assembler,
5817 since it also occurs in the xconfig file.
5819 * findvar.c (registers): Allocate some slop after `registers'
5820 to prevent stray accesses from trashing the next variable.
5822 * tm-68k.h (REGISTER_BYTES): Allocate the right number of bytes
5823 on the sun-3, by changing the #ifdef from `sun3' (which is not
5824 defined by cc) to `sun'. Symptom was trashed builtin_type_XXX
5825 vars, which happened to follow `registers' in the executable.
5827 * readline/history.c (history_search): Heed gcc-2's advice
5828 and parenthesize && inside ||).
5830 * am29k-opcode.h, am29k-pinsn.c, am29k-tdep.c, remote-eb.c,
5831 tm-29k.c: Insert FSF copyright headers.
5833 * remote-eb.c: Better comments.
5835 * Makefile.dist: Update to 3.91.6.
5836 * TODO: note PREPARE_TO_STORE problem.
5838 Thu Sep 13 09:52:33 1990 Jim Kingdon (kingdon at cygint)
5840 * stack.c (frame_info): Only use FRAME_FIND_SAVED_REGS if defined.
5842 * remote.c: Wrap the whole file in #if !defined (SPECIAL_REMOTE).
5844 * infrun.c (wait_for_inferior, at end): Don't set up
5845 prev_* if the inferior no longer exists.
5847 * inferior.h (CALL_DUMMY_LOCATION): New macro, to replace
5848 CANNOT_EXECUTE_STACK.
5849 valops.c (call_function): Use it.
5851 * tm-convex.h: Add CALL_DUMMY_LENGTH for use by PC_IN_CALL_DUMMY.
5853 * inferior.h (PC_IN_CALL_DUMMY): New macro.
5854 infrun.c (wait_for_inferior, 2 places): Use it.
5856 * values.c (value_being_returned): Only use
5857 EXTRACT_STRUCT_VALUE_ADDRESS if defined.
5859 * Move PREPARE_TO_STORE from xm-sun3.h to tm-sun3.h to do the
5860 right thing for remote-eb.c.
5862 * sun3-xdep.c: Remove extraneous call to remote_store_registers.
5863 * sun386-xdep.c, hp300hpux-xdep.c, sparc-xdep.c: Ditto.
5865 * blockframe.c: Put get_frame_saved_regs inside #if !defined
5866 (FRAME_FIND_SAVED_REGS).
5868 * findvar.c ({fetch,store}_registers): Check for
5869 REMOTE_{FETCH_STORE}_REGISTER macro.
5871 * findvar.c (get_saved_register): Add argument lval and
5872 change meaning of argument addr.
5873 findvar.c: Change calls to get_saved_register to reflect
5874 new calling convention.
5875 valops.c (value_assign): Use get_saved_register instead of
5876 find_saved_register.
5878 Sun Sep 2 12:40:20 1990 Jim Kingdon (kingdon at cygint.cygnus.com)
5880 * coffread.c (read_one_sym): Make temp_aux an AUXENT, not
5881 an (uninitialized) pointer to one. Use "&" when passing it
5884 Fri Aug 31 22:57:54 1990 Jim Kingdon (kingdon at cygint.cygnus.com)
5886 * coffread.c (getfilename): Use DGUX x_offset and x_name if
5889 * coffread.c (symbol_file_command): Put semicolon after
5891 Put safe_to_init_tdesc_context in #if defined (TDESC).
5892 Put #ifdef TDESCs in 1st column for non-ANSI cpp's.
5893 coffread.c: #include <sys/stat.h>.
5894 (read_coff_symtab): Typo: in_source_files -> in_source_file.
5895 Add missing ')' in check for "lc%" and friends. Remove
5897 Declare read_one_sym() at top of file.
5898 (read_file_hdr): Put in extra #ifdefs so MC68MAGIC and
5899 MC68WRMAGIC can have the same value without causing a duplicate
5902 Thu Sep 13 15:55:36 1990 John Gilmore (gnu at cygint)
5904 * Allow a Makefile to be built without building the
5905 tm and xm file links that screw up builds in subdirectories.
5906 This is done with `config.gdb none', then you can do things
5907 like `make gdb.tar.Z'.
5908 * tconfig/none: Config file for no target system
5909 * xconfig/none: Config file for no host system
5910 * config.gdb: If no TM or XM files are called out by the
5911 host or target file, don't make links for them.
5913 * cplus-dem.c: Add documentation.
5915 * dbxread.c (read_ofile_symtab): Turn a fatal error into a
5916 simple error, so the user's gdb doesn't crash due to some object
5917 file problem (e.g. somebody is rebuilding the file out from under
5920 * printcmd.c (print_address_symbolic): demangle the symbol.
5922 * Makefile.dist (OTHERS): Remove tdesc-lib because it has
5923 Motorola copyrights in it. Make "make gdb.tar.Z" work.
5924 (alldeps.mak): sort and uniq all results from this; duplicates
5925 hose gdb.tar.Z link building. Remove RCS files from
5926 tconfig and xconfig. Add config files for sun386. Add
5927 a few odd files to OTHERS and HFILES.
5929 Mon Sep 10 21:20:24 1990 John Gilmore (gnu at cygint)
5931 * Makefile.dist: Pull solib.c to tconfig/sun?os4.
5932 Roll version number to 3.91.5. Make lint work in bindir.
5934 * README: Document cross-debugging and new file structure.
5936 * blockframe.c: Lint. Include "value.h" to declare read_register.
5937 (find_pc_partial_function): remove duplicate line.
5939 * command.h: Lint. Declare error_no_arg and dont_repeat.
5941 * tm-news.h: Remove inadvertently duplicated stuff.
5943 * mipsread.c: Remove cache_pc_function stuff, now done cleanly.
5944 Clean up usage of misc_function_type. Declare some CORE_ADDRs.
5946 * config.gdb: Allow `config.gdb host target' form. Clean
5947 up previous change that printed bogus messages when you just said
5950 * core.c: #include "command.h" for lint.
5953 * main.c: Remove some casts of enums. Lint.
5960 * printcmd.c (initialize_printcmd): Fix thinko in inspect cmd.
5962 * sparc-tdep.c (isannulled): Take instruction as parameter, don't
5963 read it from memory. This will allow us to save ptrace calls
5964 eventually. Changed caller single_step too.
5966 * sparc-xdep.c (fetch_inferior_registers): Avoid reading regs
5967 that we aren't going to use, saving many ptrace calls, especially
5968 when watchpointing or single stepping. Use some #define's for
5970 (store_inferior_registers): Ditto.
5971 (core_file_command): Use some #define's for constants.
5973 * tm-sparc.h: Add #define's for some register numbers, so we
5974 can eliminate the use of random constants in sparc-xdep.c.
5976 * stack.c (frame_command, print_frame_info, up_command,
5977 down_command) Remove frame_changed, since it
5978 causes a bug and doesn't seem to do anything useful. In some
5979 places it was used as a flag, in others as a stack level (?).
5981 * utils.c: Use MISSING_VPRINTF rather than HAVE_VPRINTF, so the
5982 default is to use the portable (vprintf) version rather than the
5984 * xm-news.h (MISSING_VPRINTF): Add.
5986 * valprint.c (val_print): Demangle fancy vtbl printouts. Lint.
5988 Sat Sep 8 00:24:12 1990 John Gilmore (gnu at cygint)
5990 * Remove stuff that forces -Bstatic linking of gdb, and warnings
5991 about linking debugged programs -Bstatic in the sun?os4 config
5992 files in tconfig and xconfig subdirectories.
5994 * main.c (main): Remove unreached exit(0) now that we exit
5997 * Create TODO file for online bug list. There are too many
5998 "little" bugs to keep track of on paper.
6000 * Change Projects file to refer to bug-gdb@cygnus.com
6001 rather than kingdon@ai.
6003 Fri Sep 7 23:35:15 1990 John Gilmore (gnu at cygint)
6005 * Makefile.dist (VERSION): 3.91.4 now.
6007 * symtab.c (init_misc_bunches): Rename from init_misc_functions.
6008 (condense_misc_bunches): Add sanity check that misc_count is
6009 the same as the number of symbols in the bunch.
6011 * coffread.c: rename init_misc_bunches. Pass an argument
6012 to condense_misc_bunches (a zero).
6014 * dbxread.c (partial_symbol_file_read): Call init_misc_bunches
6015 every time we are called; don't rely on our caller to do it.
6016 (add_file): Remove call to init_misc_bunches.
6018 * mipsread.c: Only warn, don't error, if unknown symbol types.
6019 This keeps an old gdb from falling on its face if it sees newly
6020 extended symbol info. Rename init_misc_bunches.
6022 Fri Sep 7 22:58:15 1990 John Gilmore (gnu at cygint)
6024 * Merge in changes from Per Bothner for DECstations and other
6025 MIPS stuff. The rest is Bothner speaking:
6027 The next message is a merger of Alessando Forin's mips port with
6028 mine. I've tried to use my good if biased judgment to get
6029 the best of both. It *does* need testing.
6031 Some of the changes are general, *not* mips-specific.
6034 Didn't believe in little-endian bit order.
6035 There are still inconsistencies about whether flags
6036 like BITS_BIG_ENDIAN are integer (#if ...) or
6037 boolean (#ifdef ...). I tried to paper over them.
6039 dbxread.c,coffread.c,mipsread.c,symtab.c,symtab.h:
6040 Moved some misc_function code that was common to
6041 {dbx,coff,mips}read.c to symtab.c.
6042 In the process, I think I cleaned things up a bit.
6043 At the same time, moved obsavestring and obconcat to symtab.c.
6046 Removed obsolete condense_addl_misc_bunches (use
6047 condense_misc_bunches(1) instead).
6050 Needed to include <sys/dir>, at least on DECstations.
6052 valops.c, mips-tdep.c, tm-mips.h:
6053 Added PUSH_ARGUMENTS macro to support funny argument-pushing
6054 conventions (when STACK_ALIGN is insufficient).
6055 Needed on mips, where doubles need 8-byte alignment,
6056 but ints only need 4.
6059 Removed cruft that was not being used.
6060 Merged in many fixes (most from Frank Yellin, fy@lucid.com).
6063 Print $ before register-names (I think that makes things a little
6065 Never print two instructions, even if one delays.
6066 Removed hex-disassemble set_cmd. (This is not mips-specific,
6067 so I think the argument is whether it is generally worthwhile or not.
6068 I'm inclined to think not, given how easy it is to
6069 convert between radixes in gdb.)
6072 This is basically Alessando's code.
6073 It doesn't use obstacks; I changed it to use obstacks
6074 in a few minor places where using malloc causes a
6075 memory leak. (Probably, more places could/should be changed.)
6076 I added record_misc_function where it was missing.
6077 In symbol_file_command and add_file_command, I tried
6078 to make the code consistent with more recent versions.
6079 Minor sylistic changes in parse_procedure.
6080 Make a .gdbinfo. psuedo-symbol point back to the real
6081 procedure symbol (using the isym field).
6084 This is basically from my port, but with a lot of details
6085 and a number of routines merged in from Alessando's version.
6086 I basically used my code "raw" backtrace (use heuristics
6087 from the actual code, rather than symbol table info) - though
6088 the idea is Alessandro's. I feel my code is a little cleaner
6089 here, particularly in being a little more flexible, such as being
6090 able to handle gcc-produced code (which it now can).
6091 It also doesn't do frame caching (which is not useful
6092 more recent gdb versions).
6093 I also used my code for push_/pop_dummy, more or less.
6094 I tried to incorporate AF's code for testing sigtramp
6095 while backtracing; I probably got it wrong.
6096 Added mips_print_register, which tries to scrunch as much
6097 information as possible on a screen...
6098 Removed the skip-prologue set_cmd. As with hex-disassemble (see
6099 under mips-pinsn.c), I don't see anything mips-specific here,
6100 and I don't see it being all that useful anyway.
6103 Added a $fp psuedo-reg distinct from $fp (nice for gcc).
6104 Use more register names (rather than hard-cases numbers).
6106 Thu Sep 6 18:33:15 1990 John Gilmore (gnu at cygint)
6108 * Hack up 3.90.11 changes:
6110 * Makefile.dist (depend): parameterize $(GCC).
6111 Add solib.c and solib.o.
6112 (readline): Fix vpath for both absolute or relative SRCDIR.
6114 * blockframe.c: Fix from Schaefer@asc.slb.com for shared libs.
6115 Also, let the part I didn't understand at least compile so
6116 I can test the rest. FIXME.
6118 * dbxread.c: Fix thinko using strcmp.
6119 (init_psymbol_list): declare static.
6120 (partial_symbol_file_open): Comment cleanups better, avoid
6121 cleaning up the string table since the caller will do that.
6122 Move the stat for mod time into symbol_file_command, temporarily.
6123 (There should be a mod time for each symbol file, eventually,
6124 to control its rereading. FIXME.)
6126 * infptrace.c (PT_WRITE_D): use same value as PT_WRITE_I for
6127 SunOS, which gives error for shared libs otherwise. (From
6128 Schaefer, probably FIXME needs work for portability.)
6130 * solib.c: Move #include "param.h" to work.
6131 Lowercase all the Uppercase Letters In the Messages.
6132 (find_solib): Clean up inferior_so_name for debug printouts.
6133 Allow no argument, to mean all shared libraries.
6135 * symmisc.c: include param.h to get CLEAR_SOLIB.
6137 Wed Sep 5 18:00:08 1990 John Gilmore (gnu at cygint)
6139 * Merge in Kingdon's changes from FSF: the diffs from 3.90.9
6140 to 3.90.11. ChangeLog entries below are from this.
6142 Wed Jun 13 09:17:39 1990 Jim Kingdon (kingdon at mole.ai.mit.edu)
6146 * Makefile.dist (HFILES): Add tm-sunos.h.
6148 Tue Jun 12 16:15:26 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
6152 * Makefile.dist (gdb.tar.Z): Change linking of config so it works.
6154 Thu Jun 7 16:22:27 EDT 1990 Jay Fenlason (hack@ai.mit.edu)
6156 * sparc-opcode.h Added single-operand version of rett.
6158 Mon Jun 4 18:12:31 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
6160 * m-sparc.h (REG_STRUCT_HAS_ADDR, STRUCT_ARG_SYM_GARBAGE):
6161 Put parens around gcc_p in expansion.
6163 Thu May 24 15:44:51 1990 Jim Kingdon (kingdon at mole.ai.mit.edu)
6165 * utils.c (lines_to_list): Return 10 if lines_per_page == 0.
6167 Wed May 23 16:36:04 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
6169 * Changes for Sun shared libraries:
6170 blockframe.c (find_pc_partial_function): If a non-text symbol
6171 is found, set *address = pc - FUNCTION_START_OFFSET.
6172 breakpoint.c (insert_breakpoints) [DISABLE_UNSETTABLE_BREAK]:
6173 Disable breakpoints instead of giving an error.
6174 source.c (select_source_symtab): Initialize cs_pst.
6175 symmisc.c: Call CLEAR_SOLIB if defined.
6176 symtab.h: Make text{low,high} CORE_ADDR not int.
6177 (psymtab): New field addr.
6179 dbxread.c: Move DECLARE_FILE_HEADERS outside functions.
6180 (record_misc_function): Give correct type for N_DATA symbols.
6181 (condense_misc_bunches): do "misc_function_count = j" regardless
6183 Take code which is shared between symbol_file_command and
6184 add_file_command and put it into partial_symbol_file_{open,read}.
6185 Split add_file_command into add_file_command and add_file.
6186 Make psymtab_to_symtab read in the string table if the file
6188 Two new parameters to read_dbx_symtab and start_psymtab.
6189 tm-sunos.h: New file.
6191 Tue May 22 17:43:03 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
6193 * infcmd.c: Change cont_command to continue_command and "cont"
6196 Mon May 21 14:41:41 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
6198 * breakpoint.c (enable_breakpoint): Get value of watchpoint.
6200 * defs.h [sparc]: Use <alloca.h> regardless of __GNUC__.
6202 * values.c (USE_STRUCT_CONVENTION): Check for structures of
6203 size 1,2,4,8 rather than size < 8.
6205 * dbxread.c (dbx_lookup_type): Do f->length *= 2 as many times
6206 as necessary, not just once.
6208 * sparc-opcode.h: Add a bunch of new opcodes which Sun as supports.
6210 Thu May 17 15:04:09 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
6212 * {t,x}m-sun386.h, sun386-xdep.c, {x,t}config/sun386
6214 * tm-news.h: Add CALL_DUMMY_*.
6216 * tm-68k.h: Remove duplicate comment at FRAME_FIND_SAVED_REGS.
6218 * config.gdb: In list_host, list_target, use ${i}, not $i.
6220 Tue May 15 21:27:12 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
6222 * source.c (find_source_lines) [BROKEN_LARGE_ALLOCA]: Use xmalloc.
6224 * sparc-opcode.h: Change all store floating-point state register
6225 instructions to have the right match & lose fields.
6227 Sat May 5 12:39:18 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
6229 * Makefile.dist: Move -I${srcdir} to GLOBAL_CFLAGS and pass
6231 config.gdb: If srcdir != ., create readline directory and
6232 copy a makefile into it.
6234 * wait.h, infrun.c: Change WRETCODE to WEXITSTATUS for
6235 consistency with POSIX.
6237 * breakpoint.c (bpstat_stop_status): Disable watchpoint
6238 when we exit its exp_valid_block.
6240 Tue Sep 4 11:46:46 1990 John Gilmore (gnu at cygint)
6242 * Makefile.dist: Bump version to 3.91.3.
6244 * Clean up handling of breakpoint commands (somewhat).
6245 Prompted by Tiemann bug report "cont 10" doesn't work any more.
6247 inferior.h: Add breakpoint_proceeded to inferior status struct
6248 and globals; save it and restore it.
6249 (clear_breakpoint_commands): Cleanup, remove old #define.
6251 infrun.c (clear_proceed_status): Set breakpoint_proceeded.
6252 (save_inferior_status, restore_inferior_status): handle it also.
6253 (proceed): Remove earlier code that set breakpoint_proceeded.
6254 It is now set only in clear_proceed_status.
6255 (clear_proceed_status): Cleanup, use bpstat_clear rather
6256 than clear_breakpoint_commands. No callers need the stop_bpstat
6257 between clear_proceed_status and proceed.
6259 infcmd.c: Add breakpoint_proceeded definition and comment.
6260 (cont_command, jump_command, signal_command): Move call to
6261 clear_proceed_status right next to call to proceed.
6263 breakpoint.c (bpstat_do_actions): Avoid clobbering our
6264 caller's argument while running down the chain of breakpoints.
6265 Use new variable "breakpoint_proceeded" to determine when
6266 a command that it executes moves the inferior past the
6268 (bpstat_clear): Handle NULL argument.
6269 (bpstat_clear_actions): Avoid useless call to
6270 breakpoint_auto_delete.
6271 (delete_breakpoint): Clean up bpstat's that are pointing to
6272 the deleted breakpoint from the stop_bpstat chain.
6273 (breakpoint_auto_delete): Simplify.
6275 * Clean up handling of EOF, error on stdin, etc. This was
6276 prompted by a network problem that caused gdb to go into an
6277 infinite loop filling up its malloc'd memory.
6279 main.c (return_to_top_level): Cleanup: call bpstat_clear_actions,
6280 not clear_breakpoints_commands, which is now gone.
6281 (main): If command_loop returns (e.g. from EOF on stdin), do
6282 a quit_command (looping back to command_loop if quit_command
6283 doesn't really quit).
6284 (command_loop): check result from command_line_input and
6285 exit if it returns NULL, rather than passing the NULL to
6287 (gdb_readline): Free malloc'd result space before returning
6290 * utils.c (query): Handle C-d to mean "yes", just as if the
6291 input was not a terminal. Also avoid infinite loop if EOF
6292 occurs in mid-input-line before newline. This allows
6293 query to be used at EOF on stdin with reasonable results.
6295 * infrun.c (proceed): Set breakpoint_proceeded.
6297 * values.c (value_as_long): Avoid infinite recursion for enums.
6298 (_initialize_values): Fix typo in help msg (kingdon).
6300 * Makefile.dist (RL_LIB): Use RL_LIB_DEP for dependencies,
6301 RL_LIB for linking. This allows -lreadline for linking
6302 and nothing for dependencies, once readline is a real library.
6304 * config.gdb: Jim Kingdon: give useful error message if the
6305 host or target type is not recognized.
6307 * defs.h (alloca): SPARC <alloca.h> does not declare alloca,
6308 it just defines it. Dumb, but deal with it.
6310 * Jim Kingdon suggests:
6311 in xconfig/sun3os4, CFLAGS should be XM_CFLAGS.
6313 Wed Aug 29 18:03:27 1990 John Gilmore (gnu at cygint)
6315 * Makefile.dist (VERSION): Bump version # to 3.91.2.
6317 * Clean up Bothner's changes.
6319 * blockframe.c (clear_pc_function_cache): New function.
6320 * blockframe.c: remake cache_pc_function_* static.
6321 * dbxread.c (symbol_file_command): remove references to
6322 cache_pc_function_* variables.
6323 * dbxread.c (read_struct_type): Use VOFFSET_STATIC.
6324 * printcmd.c: Avoid kludging a global variable (addressprint)
6325 to avoid printing the address of a string twice. Instead,
6326 pass the format letter 's' down low enough that it can be seen
6327 to avoid this problem.
6328 (print_formatted): Pass format arg to value_print.
6329 (restore_addressprint): Remove function.
6330 (do_examine): Avoid hacking addressprint, cleanups and such.
6331 (print_frame_args): Add a comment to a Bothner change.
6332 * symtab.h: define VOFFSET_STATIC and use it instead of "-1".
6333 * symmisc.c (free_all_symtabs): Call clear_pc_function_cache
6334 to wipe out the values cached in blockframe.c.
6335 * symtab.c (find_method): Add comment saying how big you must
6336 allocate to be "big enough". Per being terse again.
6337 * valprint.c (val_print): Handle format letter "s" to print
6338 strings without addresses. Add comment to vtbl printing code
6339 which casts with wild abandon. Rearrange reference-printing
6341 @0xaddr: value (print w/addressprint)
6342 value (print w/~addressprint)
6343 @0xaddr (parameter lists w/addressprint)
6344 or nothing (parameter lists w/o addressprint)
6346 Tue Aug 28 10:47:18 1990 John Gilmore (gnu at cygint)
6348 * Merge more changes from Per Bothner:
6350 Gdb's handling of TYPE_CODE_REF was so counter-C++ (and otherwise
6351 annoying) that I tried to improve it. Here are my suggestions.
6353 These patches all attempt to handle TYPE_CODE_REF (as in C++) better.
6356 Do automatic de-reference when taking the address of a reference.
6358 Don't deref_ref when printing parameter lists.
6360 More attempts at treating refernences properly.
6362 In val_print, if deref_ref==0, don't print dangling " = ".
6364 Add COERCE_REF macro, which de-references an REF.
6366 * Merge changes from Per Bothner:
6368 * Fixed (Sony news)-specific configuration problems.
6369 * Fixed other problems with using vanilla pcc and libc (enum problems;
6370 assumption that vsprintf exists).
6371 * Some major speed-ups (finc_pc_partial_function now caches a match;
6372 parsing avoids duplicate symbol_lookup calls).
6373 * Changed handling of baseclasses (no longer use baseclasses field
6374 of struct type, use the first n_baseclasses fields instead).
6375 * Various minor changes/fixes, most C++-related.
6378 Cache the most previous match from find_pc_partial_function.
6379 (Save both low and high ends of matching function's pc range.)
6380 This speeds up the loop of infrun.c:wait_for_inferior quite
6381 a bit, and makes step/next commands much zippier.
6383 Added an enum->int cast (otherwise, some compilers barf).
6385 No longer set baseclass offset to 0, since multiple
6386 inheritance now mostly works.
6387 Added a number of casts, to shut up compiler warnings
6388 (after stabs where made enums, not ints).
6389 When discarding a symbol table (in symbol_file_command),
6390 must clear the cache introduced in blockframe.c.
6391 Don't convert $vtbl_ptr_type to vtbl any more.
6392 Get rid of TYPE_BASECLASEES and baseclass_vec (see also symtab.h).
6393 Mask off sign bit emitted by g++ for virtual table offset.
6394 Set voffset to -1 (not 1) for static member functions.
6396 Changed parsing/lexing of names to avoid doing symbol lookup twice
6397 (once when lexing to determine symbol class, once for real).
6398 Now only call symbol_lookup once. Fields of 'this' win especially big.
6400 Subpress printing addr twice in the case of 'x/s addr'.
6402 lookup_basetype_type is no longer used.
6403 Add find_methods as recursive helper function to decode_line_1.
6404 This allows multiple inheritance to work.
6405 Also, once one or more matches has been found, do not look in
6406 base-classes. (Baseclass methods would be overridden, anyway.)
6408 Removed baseclasses array in struct type.
6409 Instead of using baseclasses[i], use fields[i-1].
6410 Added virtual_field_bits[i] to indicate if the i'th baseclass is virtual.
6411 Changed sign convention of voffset (previous was inconsistent).
6413 Some macros (CALL_DUMMY and relatives) were missing. Put them back.
6415 Used to assume existence of vsprintf. Re-written to not need it
6416 if HAVE_VPRINTF is undefined.
6418 typecmp was too pessimistic. Made it less so.
6420 Don't print space after address.
6421 If vtable points to a misc symbol (with 0 offset), print it,
6422 since that indicates the actual class of the object.
6423 Changed ype_print_derivation_info to use new inheritance
6424 scheme (without baseclasses vector).
6426 In value_primitive_field, fixed some bugs left over from previous set of fixes.
6427 Also, changes needed because TYPE_BASECLASSES were removed.
6429 REGISTER_U_ADDR didn't work for PC. Rewrote to use an array.
6431 Tue Aug 21 20:08:54 1990 John Gilmore (gnu at cygint)
6434 If there is no path set, and the symbols don't indicate what directory
6435 a file was compiled in, look in the current directory. But either
6436 a path or a known compilation directory will prevent this.
6439 Three independent bug fixes:
6440 * Remove the #if 0 block that breaks some stuff.
6441 * SunOS 4.1 fixed the promoted-parameter-wrong-addr bug in Sun C;
6442 adapt gdb to either SunOS 4.0.* or 4.1.
6443 * MAX_OF_TYPE and MIN_OF_TYPE thinko. By tedg@sun, I think.
6446 Instantiate the class T when looking for methods in it. (Tiemann@sun)
6449 (type_print) Demangle the name being printed.
6450 (type_print_base) Handle botched demangling without coredump (tiemann).
6453 (check_stub_method): Document routine.
6454 (tiemann) fix bug for no-arg functions
6455 Avoid clobbering beyond end of malloc'd storage.
6456 Terminate the argument list properly.
6458 Sat Aug 18 01:29:59 1990 Per Bothner (bothner@cs.wisc.edu)
6460 * Changes merged by John Gilmore:
6463 In breakpoint_1, use new print_address_symbolic instead
6464 of find_pc_partial_function. (This forces use of assembler-level
6465 addresses, and avoids misleading non-mangled source-level names.)
6467 Generalize ansi argument such that -1 means skip arglist totally.
6468 Removed global variable print_ansi_qualifiers (which made
6469 code non-reentrant), in favor of extra explicit arguments
6470 to internal routines.
6472 Add new helper function print_address_symbolic.
6473 Use find_pc_misc_function instead of find_pc_partial_function
6474 (since we want assembler-level symbols here).
6476 Print unknown function as just "f (...)", not "f (...) (...)".
6477 Use new fputs_demangled explicitly.
6479 Fixed a typing violation (problem: value.h cannot be imported
6480 without renaming many variable in this file).
6481 lookup_symbol: If no matching misc_func, look for a C++-mangled name.
6482 decode_line_1: Moved forward some never-reached code.
6483 Made decode_line_2 skip function prologues correctly.
6485 fputs_filtered should not demangle by default.
6486 Add new fputs_demangled to demangle on demand..
6488 Change value_struct_elt to use value_primitive_field (using recursive
6489 utility function search_struct_field). This allows foo.bar to work
6490 for multiple inheritance (so far only for data fields).
6491 Change check_field in the same way (recursive helper function
6492 to support multiple inheritance).
6493 (Note: there are more of these problems that I haven't fixed.
6494 Any code that says TYPE_BASECLASS (t, 1) is probably wrong.)
6495 value_of_this: 'this' symbol name is now just "this", note "$this".
6497 Don't print static members.
6498 Avoid printing "members of <type>" if there are none.
6499 Simplified type_print_derivation_info by merging duplicate code.
6500 Remove useless blank lines in type_print_base (ptype command).
6502 Added declaration of new routine value_primitive_field.
6504 Added value_primitive_field which is generalized version of
6505 value_field that can handle multiple inheritance (non-zero offsets etc).
6506 Re-implemented value_field to call value_primitive_field.
6508 Fri Aug 17 23:33:44 1990 John Gilmore (gnu at cygint)
6510 * infcmd.c -- insert else to avoid 'delete env' coredump when you
6511 delete the whole environment. Karl Berry reported the bug.
6512 * source.c - fix openp to avoid //'s in filenames, which
6513 trigger an Emacs bug causing it to not be able to find files
6514 when running gdb in a window.
6515 * dbxread.c - zap the #if 0 that botches the add-file code.
6516 It seems to work a lot better without all the code commented out.
6518 Fri Jul 20 16:58:46 1990 John Gilmore (gnu at cygnus.com)
6520 * Merge Tiemann's and Ted Goldstein's changes, detailed below,
6523 Tue Jul 17 19:34:33 1990 Ted Goldstein (tedg at golem)
6525 * Makefile - added a ${CFLAGS} to a couple of entries,
6526 added remote-sa.sparc.c
6527 * added remote.sa-sparc.c, a modification of remote.c
6528 which conducts a dialog directly with the SparcStation prom.
6529 * breakpoint.c, infrun.c, sparcdep.c added
6530 remote_insert_breakpoint(), and remote_remove_breakpoint()
6531 to breakpoint.c instead of directly writing breakpoint instructions.
6532 * sparcdep.c on remote_debugging,there is no need
6533 to remove signle step breakpoint instructions.
6534 * main.c added "-epoch" flag and "int epoch_interface" to main.c
6536 * printcmd.c - epoch interface sends lisp expressions to open up
6537 epoch windows on inspection.
6538 * valprint.c - added arrayprint, and addressprint and made adding
6539 format controls easier
6540 * wait.h added a couple of undef's because we were getting
6541 complaints about WSTOPSIG and WTERMSIG begin redefined.

6611 * valprint.c (everywhere): TYPE_NAME (TYPE) no longer comes in the
6612 form "struct ..." for GNU C++. Don't flush any part of TYPE_NAME
6613 when printing the type.
6615 Wed May 2 22:43:04 1990 Michael Tiemann (tiemann at teacake)

6637 step_resume_break_address != NULL, even if another_trap.
6638 If trap_expected and we enter sigtramp, then set up a
6640 If trap_expected is set when we hit the step_resume_break,
