3 * inflow.c: Remember whether GDB has a terminal. Avoid switching
4 terminals back and forth if we don't have one.

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

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

105 New files for i386/SVR4.
107 * tm-i386v.h: Allow START_INFERIOR_TRAPS_EXPECTED and
108 DECR_PC_AFTER_BREAK to be predefined by files including
111 * i386-tdep.c: Add supply_gregset(), fill_gregset(),
112 supply_fpregset(), and fill_fpregset() functions, which are
113 target dependent support functions for the SVR4 /proc register
116 * dwarfread.c (enum_type, struct_type): Expand recognized
117 compiler generated tags to include symbols beginning with '.' as
120 * symtab.c (sources_info): Change simple printf of error message
123 Fri Nov 29 16:04:21 1991 Roland H. Pesch (pesch at cygnus.com)
125 * doc/gdb.texinfo: remove leading comments that survived M4 but
126 described its role in the doc; add one more font to colophon;
127 strengthen disclaimer about unsupported configs.

134 Eliminate TYPE_MAIN_VARIANT and TYPE_NEXT_VARIANT. Eliminate
135 lookup_method_type. Add TYPE_TYPE_SPECIFIC macro.

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

197 * Makefile.in: Roll new files into various lists.
199 Thu Nov 21 18:26:11 1991 Fred Fish (fnf at cygnus.com)
201 * dwarfread.c (struct_type): Must initialize the c++ specific
202 portion of union types as well as struct types, since gdb attempts
203 to reference the c++ specific info for both types.
205 Thu Nov 21 10:23:52 1991 John Gilmore (gnu at cygnus.com)
207 * Makefile.in: Roll VERSION to 4.2.90.

229 Wed Nov 20 18:35:56 1991 John Gilmore (gnu at cygnus.com)
231 * Remove gdb/hp-include. Support for HP a.out oddities should be
232 in BFD, not in GDB. Move gdb/hp-include/a.out.h to include/a.out.hp.h.
234 * infptrace.c, tm-sun386.h: Cashier <a.out.gnu.h>, remove refs.
236 * configure.in, xconfig, tconfig, Makefile.in, doc/gdbint.texinfo:
237 Makefile fragments for various hosts and targets now come from
238 gdb/config/mh-* and gdb/config/mt-*. This is for consistency with
241 * rs6000-pinsn.c, rs6k-opcode.h: Clean up.
242 * rs6k-opcode.def: Delete.
244 Wed Nov 20 05:04:40 1991 Fred Fish (fnf at cygnus.com)
246 * dwarfread.c: Recognize obsolete form of AT_element_list
247 attribute still used by at least one AT&T compiler, and possibly
250 Tue Nov 19 07:53:55 1991 Fred Fish (fnf at cygnus.com)
252 * dwarfread.c (enum_type, struct_type): Ignore names invented by
253 helpful compilers for anonymous structs, unions, and enums.
255 * c-exp.y, m2-exp.y: Add defines for yymaxdepth, yy_yys, and
256 yy_yyv, so multiple parsers produced by SVR4 versions of yacc
257 can coexist in the same executable without collision.
259 * symtab.h: Add declaration for lookup_template_type() to kill
260 compiler warnings about conversions from int to pointer.
262 Mon Nov 18 17:45:18 1991 Fred Fish (fnf at cygnus.com)
264 * procfs.c: Move inclusion of defs.h to before param.h, as in
265 all the other source files that include both. This is required
266 to supply some typedefs that are used in files included by param.h.
268 * m68k-tdep.c (m68k_skip_prologue): Add generic m68k support for
269 skipping function prologues, ala the other cpu families (i386,
270 mips, m88k, etc). Add the ability to skip movm and fmovm
271 instructions in the prologues. Still needs support for profile
272 (-p compiled) prologue sequences (FIXME).
274 * tm-68k.h: Change SKIP_PROLOGUE macro to use the new generic
275 m68k prologue skipping function by default.
277 * tm-altos.h, tm-isi.h: Continue to use the old definition of
280 Mon Nov 18 15:12:45 1991 John Gilmore (gnu at cygnus.com)
282 * Makefile.in: Remove tdesc stuff, and extra blanks before colons.
283 * blockframe.c: Remove tdesc-related code. Default
285 * infrun.c: Remove tdesc-related code.
286 * m88k-tdep.c (frame_chain_combine, init_frame_pc): Remove copies
287 of defaultable things.
288 * tm-m88k.h: New file, common to all Moto 88k target configs.
289 Derived from tm-delta88.h.
290 * tm-delta88.h: Use it.
291 * xm-m88k.h: Common file for 88K hosts. Remove obsolete stuff.
292 * xm-delta88.h: Use it.
293 * tm-*.h: Remove FRAME_CHAIN_COMBINE macros, since all are
295 * coffread.c: Remove tdesc stuff.
296 * tconfig/delta88, tconfig/m88k: Remove tdesc stuff.
297 * xconfig/m88k: Rename tm-88k.h to tm-m88k.h.
299 Mon Nov 18 13:51:37 1991 Per Bothner (bothner at cygnus.com)
301 * source.c (open_source_file): If openp fails, try again
302 using just the base (non-directory) part of the filename.
303 This solves various annoying problems, such as when the
304 source was compiled with an absolute pathname - and the
305 source files have moved. Or if the source was compiled
306 using a relative pathname, it can be more convenient
307 to just specific the source directory to the dir command.
309 Mon Nov 18 00:04:41 1991 Fred Fish (fnf at cygnus.com)
311 * cplus-dem.c (munge_function_name): Add missing third arg to
312 instance of call to do_type().
314 * dwarfread.c: Changes to match new dwarf.h. Remove
315 AT_deriv_list, AT_loclist, AT_incomplete, AT_const_data,
318 Sun Nov 17 16:20:53 1991 Michael Tiemann (tiemann at rtl.cygnus.com)
320 * symtab.h (struct type): Moved C++-specific fields into new type
321 `struct cplus_struct_type'. Now takes 10% less memory. Many
323 * symtab.c (init_type): Don't set fields belonging to
324 TYPE_CPLUS_SPECIFIC unless TYPE is TYPE_CODE_STRUCT.
325 * buildsym.c (read_type): Allocate TYPE_CPLUS_SPECIFIC for
327 (read_struct_type): Ditto. Also, add comments about how we can
328 deduce TYPE_VPTR_FIELDNO from inheritance info and fieldname info.
329 * coffread.c (decode_base_type): Allocate TYPE_CPLUS_SPECIFIC for
331 (read_struct_type): Ditto.
332 * dwarfread.c (struct_type): Ditto.
334 * symtab.c (read_range_type): Don't set TYPE_MAIN_VARIANT.
335 (lookup_pointer_type): Don't use or set TYPE_MAIN_VARIANT.
336 (lookup_reference_type): Ditto.

345 * mipsread.c (parse_partial_symbols): patch to keep DEC C
346 compiler from making gdb bomb out. Thanks to Ed Santiago!
348 Thu Nov 14 19:27:30 1991 Fred Fish (fnf at cygnus.com)
350 * symfile.c: Add function compact_misc_function_vector() to
351 remove duplicate misc function vector entries. See comments
352 in source for why this is necessary/desirable.
354 * dwarfread.c: Add misc function type parameter to internal
355 record_misc_function(). Remove calls to init_misc_bunches()
356 and condense_misc_bunches(), these are now done in elfread.c.
358 * elfread.c: Add support for reading bfd canonical symbol tables
359 and generating misc function vector entries for global and
360 absolute symbols. Do calls to init_misc_bunches() and
361 condense_misc_bunches() where they will enclose all calls to
362 record_misc_function(), including those in dwarfread.c.
364 Thu Nov 14 17:02:11 1991 Roland H. Pesch (pesch at cygnus.com)
366 * doc/Makefile.in: new targets gdb.me, gdb.ms, gdb.mm
367 (roffable documentation).
368 * doc/gdb.texinfo: embedded hints (as comments) for better
369 texi2roff conversion.
371 Thu Nov 14 13:18:25 1991 John Gilmore (gnu at cygnus.com)

385 Motorola 88000 port without tears, I mean without tdescs.
387 * m88k-tdep.c: Blow away all tdesc stuff.
388 Provide functions for all the frame-related macros in
389 tm-delta88.h. Adopt i960-style EXTRA_FRAME_INFO.
390 (examine_prologue, frame_find_saved_regs, skip_prologue): borrow
391 from i960-tdep.c and adapt to the function prologues on the 88k.
392 (read_next_frame_reg): Borrow from mips-tdep.c.
393 FIXME: frame_locals_address should go away.
395 * tm-delta88.h: Dump all the tdesc stuff.
396 Macros for all frame-related stuff call fns of same name.
397 Remove duplicated definitions. FP_REGNUM becomes same as
400 * xm-88k.h: Eliminate lots of library dependencies, now handled
401 in libiberty. Eliminate KDB nonsupport.
403 * doc/gdbint.texinfo: Add rudiments on frames. FIXME, add more.
406 * stack.c (frame_info): Mark frameless functions.
407 Print locals address (FIXME, remove if same).
408 * blockframe.c: Comment changes, FIXME after.
409 * coffread.c: Even without TDESC, need to zap "@" symbols.
410 Don't register for wierd format names; change the names in BFD.
412 * alloca.c, language.c, tdesc.c: Lint.
413 * tdesc.c, tdesc-lib: FIXME: remove these.
415 Tue Nov 12 19:30:22 1991 John Gilmore (gnu at cygnus.com)
417 * Makefile.in: Add tdesc library support. Fixups to lint,
420 Tue Nov 12 13:43:26 1991 Per Bothner (bothner at cygnus.com)

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

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

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

512 start_psymtab, psymtab_to_symtab_1, read_ofile_symtab,
513 dbx_psymtab_to_symtab, ): Use bfd ops, don't use file descriptor.
514 Pass objfile. Change callers.
515 (fill_symbuf, SWAP_SYMBOL): Take bfd as arg.
516 (read_dbx_symtab): Just wipe out new symbols, not all, on error.
517 (end_psymtab): Blow away psymtab if empty.
518 (process_symbol_pair): Swallow into read_ofile_symtab.
519 (process_one_symbol): Use push_context and pop_context.
520 (virtual_context): Delete #if 0'd obsolete stuff.
522 * buildsym.c (end_symtab): Pass objfile.
523 (dbx_lookup_type): Handle null typevector.
524 (dbx_alloc_type): Check file number, not sym number, for -1.
525 (find_symbol_in_list): Add for xcoffread.
526 (start_symtab): Default typevector is empty. Keep reusing same
528 (end_symtab): Take objfile argument and pass it to
529 allocate_symtab. Don't make a symtab if no blocks or symbols.
530 Handle empty typevector.
531 (push_context): New function for context stack nesting.
532 (read_type): Mark FIXME where we need to reintroduce type smashing.
534 * buildsym.h (pop_context): Macro, paired with push_context.
535 (subfile_stack): Move here from dbxread.c.
537 * coffread.c (end_symtab, read_coff_symtab): Take and use objfile arg.
538 (read_coff_symtab): Cleanup by freeing objfile, not all symtabs.
540 * mipsread.c (read_mips_symtab, parse_partial_symbols, parse_fdr,
541 new_psymtab, new_symtab): Take and use objfile arg.
543 * dwarfread.c (scan_compilation_units, start_psymtab,
544 process_dies, end_symtab, dwarf_build_psymtabs,
545 read_lexical_block_scope, read_func_scope, read_file_scope): Take
546 and use objfile argument.
547 (psymtab_to_symtab_1, read_ofile_symtab): Don't take or use file
548 descriptor. Use BFD internal functions instead.
549 (end_symtab): Call global allocate_symtab.
551 * elfread.c, target.c: Minor changes to accommodate objfiles.
552 * symtab.h: partial_symbol_table has no symfile_name member now.
553 (fn_fieldlists voffset): avoid non-int bitfield.
554 (struct symtab): Add objfile * and objfile_chain * of symtabs.
555 (struct partial_symtab): Add objfile * and objfile_chain * of
556 psymtabs. Remove symfile_name.
558 * symmisc.c: Lose free_all_symtabs, free_all_psymtabs.
559 (printsyms_command): Rename from print_symtabs. Add selective
560 listing if 2nd argument given. Print objfile info.
561 (printpsyms_command): Rename from print_partial_symtabs. Ditto all.
562 (printobjfiles_command): New; prints objfiles lists, and checks
563 for consistency of symtab, psymtab, and objfile lists.
565 * symfile.h, symfile.c, symtab.h: Lint
567 Fri Nov 8 23:38:48 1991 John Gilmore (gnu at cygnus.com)
569 * command.c: Include param.h.
570 * defs.h (warning_setup, warning): Declare.
571 * expprint.c (print_subexp, UNOP_MEMVAL case): Lint.
572 * inflow.c (new_tty): Use USE_O_NOCTTY #define.
573 * language.c, printcmd.c (print_scalar_formatted), signame.c,
576 Thu Nov 7 18:26:15 1991 Steve Chamberlain (sac at rtl.cygnus.com)
578 * Makefile.in: link with libiberty after libreadline, since
579 readline might want something in libiberty.
580 * m88k-xdep.c: Fixed the register offsets in the ptrace_user
581 struct for BCS 88k machines.
582 * xm-m88k.h: don't define USIZE if already defined.
583 * configure.in: Added delta88 target.
585 Thu Nov 7 04:51:19 1991 John Gilmore (gnu at cygnus.com)
587 * am29k-pinsn.c, am29k-opcode.h: Fix decoding of mtacc, dmac, fmac.
589 * tm-*.h: Remove READ_DBX_FORMAT, COFF_FORMAT, and
590 READ_MIPS_FORMAT, which have been unused since BFD. Still
591 remaining is COFF_NO_LONG_FILE_NAMES.
592 * tm-sun3.h, tm-altos.h: Remove detritus accidentally left from
593 function calling code moved to m68k-tdep.c.
595 Wed Nov 6 17:21:59 1991 John Gilmore (gnu at cygnus.com)
597 * coffread.c: Eliminate c_nsyms in favor of c_naux.
598 Complain if no auxents on .bf and .ef FCN symbols, and assume
599 lots of line numbers.
600 (init_linenos, enter_linenos): Use a sentinel at the end of the
601 read-in linenos, to make for a fast, safe loop-end test.
603 Wed Nov 6 02:54:08 1991 Steve Chamberlain (sac at cygnus.com)
605 * coffread.c (read_coff_symtab): coffread used to rely on the
606 x_sym.x_misc.x_lnsz.x_lnno field giving the # of linnos in a
607 function. Two of the formats I'm using (29k and 88k) don't seem to
608 set it. Ths patch to fcn_last_line and (enter_linenos) is an
609 attempt to use the actual size of the linno table in the file to set
610 the number of linenos to process.
612 Tue Nov 5 22:47:46 1991 Steve Chamberlain (sac at cygnus.com)
614 * Makefile.in: put a - infront of the mv y.tab.c c-exp.tab.c and
615 mv y.tab.c m2-exp.tab.c, so that if bison is used, and the files
616 are created in place, so the mv fails, then the make continues.
618 Tue Nov 5 16:47:47 1991 Per Bothner (bothner at cygnus.com)
620 Add C++ as a separate language.
621 * defs.h (enum language): Add language_cplus.
622 * dwarfread.c (end_symtab): Support language_cplus.
623 * c-exp.y: Add new struct language_defn cplus_language_defn.
624 Don't set c to be the default language (see main.c).
625 * c-exp.y (yylex): Only look for field of this if
626 language is C++. (First difference from C!)
627 * language.c: Add case branches for C++ (currently, all
628 the same as C). Also, add c++ to "usage" note for "set lang".
629 * valprint.c (typedef_print). Add case branches for C++.
630 * main.c (main): New way to set initial language: Look at
631 file extension of psymtab containing main(). (Same as we
632 do for symtabs, but avoid loading the symtab yet.)
633 * symtab.c: New routine find_main_psymtab(), used by main()
634 to set initial language.
635 * symfile.c (allocate_symtab): Move code for mapping file
636 extensions-> languages to new deduce_language_from_filename().
638 Fix a C++ problem when looking for methods in super-classes.
639 There was confusion between base and derived types.
640 * valops.c (value_fn_field): Change function interface.
641 * values.c: Use new value_fn_field interface.
643 Mon Nov 4 10:49:33 1991 Per Bothner (bothner at cygnus.com)
645 * infrun.c: Fixed typo in comment.
646 * utils.c: All the v*fprintf emulation is now in libiberty,
647 so we can get rid of some junk.
648 * xm-sun3os4.h, xm-sun4os4.h, xconfig/decstation, xconfig/i386sco,
649 xconfig/sun3os4, xconfig/sun4os4: Don`t need HAVE_STRSTR any more.
650 * m68k-pinsn.c (print_insn_arg): Support BB/BW/BL
651 type operands, as used by branch instructions.
652 * gmalloc.c: Fix prototype of memcpy.
653 * elfread.c: Comment out register_addr, since it conflicts
654 with the one in coredep.c.
655 * buildsym.h: Remove extern declarations of two functions
656 that are really static in buildsym.c.
657 * tm-mips.h: Add symbolic names for more registers.
658 * mips-xdep.c (store_inferior_registers): Use new register names.
659 * xm-mips.h: Simplify REGISTER_U_ADDR, since it is now
660 only used for core files, not ptrace. Therefore,
661 the KERNEL_U_ADDR hack is no longer needed.
662 The mapping to ptrace number is now in in mips-xdep.c.
663 * mips-xdep.c: Define REGISTER_PTRACE_ADDR (using the
664 mapping from the old REGISTER_U_ADDR), and use it
665 in {fetch,store}_inferior_registers.
666 * mipsread.c: Rename #include ecoff.h to new name coff-mips.h.
667 * mips-tdep.c (mips_push_dummy_frame, mips_pop_frame):
668 Save/restore FP regs correctly (?).
669 * dbxread.c: Remove duplicate define_symbol and type_synonym_name
670 (these had been previously moved to buildsym.c).
671 Hence, define_symbol becomes extern instead of static.
672 * buildsym.c (read_struct_type): Comment out bogus handling
673 of C++ operator methods. Minor hacking of reading of class
674 contexts. Make define_symbol non-static, so dbxread.c can call it.
676 Fri Nov 1 11:05:47 1991 John Gilmore (gnu at cygnus.com)
678 * mipsread.c (read_mips_symtab, read_the_mips_symtab): Use real
679 filename with error messages.
680 * stack.c (frame_select_command): Rename to select_frame_command
681 to avoid "fr" and "fra" having nonunique completions.
682 * symfile.c (sort_symtab_syms): Ignore sort of zero symtab *.
683 (symfile_init): Print file format name when unable to handle it.
684 (free_named_symtabs): Use BLOCKVECTOR rather than obsolete BLOCKLIST.
685 * symmisc.c (free_symtab): Only free linetable if nonzero.
686 * symtab.h: Remove obsolete BLOCKLIST macros.
688 Thu Oct 31 18:12:43 1991 Stu Grossman (grossman at cygnus.com)
690 * infrun.c (wait_for_inferior): another stepi/nexti fix. Ensure
691 that stop_step is 1 at bottom of main loop. I don't know why this
692 needs to be done, but it helps me sleep better at night.
694 Sun Oct 27 18:18:39 1991 Stu Grossman (grossman at cygnus.com)
696 * main.c (initialize_history): Read history after reading all
699 Sun Oct 27 14:09:25 1991 John Gilmore (gnu at cygnus.com)
701 * buildsym.c: Break out initial malloc sizes.
702 (record_line): Record directly in a subfile. Alloc on demand.
703 (compare_line_numbers): Add from xcoffread.c.
704 (end_symtab): New params say whether to sort pendings and
705 linetable. Patch block stabs if defined. Shrink linetable before
706 allocating the symtab.
707 * buildsym.h: Delete line_vector* and prev_line_number. Add
708 global_stabs and file_stabs for xcoffread.
709 * dbxread.c (start_subfile): Move to buildsym. Change above calls.
710 * symtab.h: LINETABLE(symtab) can now be null. Zap LINELIST.
711 * symmisc.c, symtab.c: Cope with null LINETABLEs.
713 * blockframe.c: Pass fromleaf to INIT_EXTRA_FRAME_INFO.
714 * tm-29k.h, tm-88k.h, tm-i960.h, tm-irix3.h, tm-mips.h, tm-pyr.h,
715 tm-sparc.h: Accept fromleaf parameter.
716 * c-exp.y (yyerror): Pass error message if given.
717 * configure.in: Add rs6000 host and target.
718 * inflow.c (new_tty): O_NOCTTY kludge for RS/6000.
719 * symfile.h (entry_point): Add.
721 Sat Oct 26 00:16:32 1991 John Gilmore (gnu at cygus.com)
723 * buildsym.c: New file. Breaks out symbol-table-building routines
724 from dbxread.c, so they can be shared with xcoffread.c.
725 * buildsym.h: New file. Declarations for buildsym.c users.
726 * dbxread.c: Remove large chunks into buildsym.c.
727 * Makefile.in: Add buildsym.c and buildsym.h.
729 * symfile.c (syms_from_bfd): New routine.
730 (add_symbol_file): Call it to do the real work.
731 (syms_from_bfd): Initialize entry_point before calling symfile_init.
732 * symtab.h, symfile.c, coffread.c, mipsread.c, dwarfread.c:
733 Avoid declaring or setting entry_point (symfile.h & symfile.c cope).
735 Fri Oct 25 10:58:16 1991 Mark Eichin (eichin at cygnus.com)
737 * cplus-dem.c (cplus-demangle): added support for templates, static
738 data, and the new (correct) mangling for destructors.
740 * dwarfread.c: (dwarfwarn): created a varargs version of
741 dwarfwarn, for non __STDC__ compilers.
743 * c-exp.y: (yylex): added match for "template" token.
744 (typebase): added TEMPLATE name '<' type '>' clause, for explicit
745 specification of template types.
747 * symtab.c: (lookup_template_type): new function for finding
748 templates in symbol table.
749 (type_name_no_tag): changed to explicitly check for s/u/e at the
750 beginning of the symbol - if it is a template, none of these will
751 be there (but the name will still contain spaces.)
753 Fri Oct 25 18:59:32 1991 Per Bothner (bothner at cygnus.com)
755 Various fixes to improve g++ debugging.
756 * symtab.h: Add is_const and is_volatile flags for each method.
757 These are bit fields - take their space from voffset,
758 which shrinks to 30 bits. Since voffset is now a bitfield,
759 make it unsigned for portability. This changes its interpretation
760 slightly: Static methods now have voffset 1 instead of -1,
761 and virtual offsets start at 2, not 1.
762 * symtab.c: Renamed gdb_mangle_typename to gdb_mangle_name,
763 since it now returns an entire magled method name, not just
764 the type part. This avoids some duplication.
765 It also allows us to correctly mangle const and volatile
766 methods (using the new is_const and is_volatile bit fields
768 * valprint.c (type_print_base), values.c (check_stub_method):
769 Simplify by using new gdb_mangle_name.
770 * values.c (value_headof): Fix to correctly handle single
771 inheritance (actually two fixes, either of which suffices).
772 * dbxread.c (read_struct_type): Handle const and volatile
774 * dbxread.c (read_struct_type): Yet one more place where
775 we must handle '\\' continuations.
776 * valprint.c (vtbl_ptr_name): Add final '\0'.
778 Fri Oct 25 16:06:38 1991 Stu Grossman (grossman at cygnus.com)
780 * tm-sparc.h, tm-68k.h (EXTRACT_RETURN_VALUE): fix output of
781 short return values for sparc and 68k. Patch from Paul Eggert.
783 * coffread.c, coredep.c, i386-xdep.c: install patches for
784 SysV/386 3.2 from Mauro DePalma.
786 Fri Oct 25 02:02:13 1991 John Gilmore (gnu at cygnus.com)
788 * core.c (core_file_info), exec.c (exec_file_info): Print file
789 type. Use printf_filtered.
791 * valops.c (value_fetch_lazy): Avoid 0-length fetches.
793 Thu Oct 24 23:06:40 1991 Fred Fish (fnf at cygnus.com)
795 * dwarfread.c: Add casts to remove compiler warnings.
797 * tm-3b1.h, tm-68k.h, tm-altos.h, tm-amix.h, tm-hp300bsd.h,
798 tm-hp300hpux.h, tm-isi.h, tm-news.h, tm-pn.h, tm-sun2.h,
799 tm-sun3.h: Remove locally duplicated code for calling functions
800 in the inferior. The only differences were in the specific trap
801 vectors used and whether or not an fpu was present. These are
802 now handled by appropriate definitions of BPT_VECTOR and
803 HAVE_68881 respectively. Other minor obvious cleanups.
805 * valops.c: Correct a minor misspelling.
807 * utils.c: Remove local BSD/USG hacks that are now in libiberty.
809 * dwarfread.c: Remove prototype for dwarfwarn. Does not work
812 Thu Oct 24 09:33:44 1991 John Gilmore (gnu at cygnus.com)
814 * stack.c (frame_command): Always print. Use new
815 frame_select_command to select a frame without printing.
817 * dwarfread.c: Use <varargs.h>, since <stdarg.h> is not portable.
819 Thu Oct 24 01:32:51 1991 Fred Fish (fnf at cygnus.com)
821 * dwarfread.c: New file for DWARF debugging format support.
823 * elfread.c: New file for ELF object file format support.
825 * procfs.c: New file for SVR4 /proc (process file system) support.
827 * tm-amix.h, xm-amix.h, tconfig/amix, xconfig/amix: New files for
830 * xm-svr4.h, tm-svr4.h: New files for SVR4 support.
832 * xm-m68k.h: New file for host machines with m68k cpu.
834 * Makefile.in: Add elfread.c and dwarfread.c to SFILES_MAINDIR.
835 Add elfread.o and dwarfread.o to OBS.
837 * symfile.h: Add "elf" to list of supported formats in comment.
839 * c-exp.y, defs.h, symtab.h, valprint.c: Add three new builtin
840 types to gdb, builtin_type_long_double, builtin_type_complex, and
841 builtin_type_double_complex. Add and use new TARGET_SHORT_BIT,
842 TARGET_INT_BIT, TARGET_LONG_BIT, TARGET_FLOAT_BIT,
843 TARGET_DOUBLE_BIT, TARGET_LONG_DOUBLE_BIT, TARGET_COMPLEX_BIT, and
844 TARGET_DOUBLE_COMPLEX_BIT, as the sizes in bits of the indicated
845 types on the target machine (ala the existing TARGET_LONG_LONG_BIT).
847 * infrun.c: When using SVR4 /proc interface instead of ptrace(),
848 call proc_set_exec_trap() to setup child to stop at first instruction.
850 * inftarg.c: When using SVR4 /proc interface, call proc_wait()
853 * m68k-tdep.c: Add new routines supply_gregset(), fill_gregset(),
854 supply_fpregset(), and fill_fpregset(), which are machine
855 dependent support routines for SVR4 /proc interface.
857 * utils.c: Add warning_setup() and warning(). Warning() behaves
858 the same as error() except that it returns normally rather than
859 jumping back to command level. Modules that don't want to call
860 warning() for some reason, but want to produce their own warnings,
861 can call warning_setup() to ensure compatibility with the way
862 warning() and error() deal with the terminal.
864 * symtab.c: Make internal errors produce more useful messages.
866 * tm-68k.h: Move code that is duplicated in almost every single
867 m68k based machine's configuration files to this common file.
868 Duplications in the configuration files still need to be removed
871 * infrun.c (child_create_inferior): System V versions must call
872 setpgrp() with no arguments, to comply with prototyping typically
875 * munch: Add support for SVR4 style nm output.
877 * dbxread.c, mipsread.c symmisc.c, symtab.c: Remove the object
878 file specific fields from the partial symbol table structure and
879 replace them with a pointer to private data for each different
880 flavor of object file reader to initialize appropriately.
882 Wed Oct 23 09:38:20 1991 John Gilmore (gnu at cygnus.com)
884 * xconfig/sun[34]os4: Add note about strstr botch on sunos4.0.3c
887 * mipsread.c (fixup_undef_type): New function. If a struct /
888 union / enum is defined in a header file but nowhere else used,
889 (by typedefing, pointer referencing or declaration) the mipsread code
890 builds the complete tree for the structure but leaves its code as
891 TYPE_CODE_UNDEF as it doesn't know what kind of aggregate it is.
892 Guess its type based on the details of the members.
894 Tue Oct 22 18:04:32 1991 Stu Grossman (grossman at cygnus.com)
896 * infrun.c (wait_for_inferior): Check return value from
899 Mon Oct 21 17:47:03 1991 Stu Grossman (grossman at cygnus.com)
901 * infrun.c (wait_for_inferior): fix stepi/nexti that was broken
902 by my last edit to this routine.
904 Mon Oct 21 14:27:43 1991 John Gilmore (gnu at cygnus.com)
906 * tm-sun3.h (FIX_CALL_DUMMY): problem with cross debugging.
907 FIX_CALL_DUMMY does unaligned accesses and/or forgets to byte swap
908 the values before putting them into the dummy code. (From Peter
911 Mon Oct 21 10:04:39 1991 Steve Chamberlain (steve at rtl.cygnus.com)
913 * configure.in: added ebmon target.
915 Wed Oct 16 22:49:58 1991 John Gilmore (gnu at cygnus.com)
919 * Makefile.in: Roll VERSION to 4.2.
920 * README, TODO, WHATS.NEW: Update.
922 * core.c (core_open): Improve error message for bad file.
923 Pass .reg virtual memory address to fetch_core_registers to help
924 it find the registers in the core-file header.
925 * coredep.c (fetch_core_registers): Take new argument, use it,
926 and pass it to register_addr to locate the block of registers.
927 * xm-mips.h: Update KERNEL_U_ADDR for new scheme. Cleanup a bit.
929 * dbxread.c (read_dbx_symtab, process_one_symbol): Handle
930 Sequent N_FN_SEQ like everybody else's N_FN.
932 * main.c: Circumvent SCO cc bug with #if !!defined(USG).
933 * tm-i386v.h: #endif guck.
934 * xconfig/i386*: Remove -Dgetpagesize()=4096 kludge.
935 * xconfig/i386sco: Add HAVE_STRSTR to avoid ANSI bdeath.
936 * xconfig/tahoe: Add REGEX, which seems to be missing.
938 * coredep.c: Add <sys/types.h> for SCOnix.
939 * dbxread.c (read_dbx_symntab): Avoid coredump on malformed file.
940 * printcmd.c (print_formatted): Flush output before disassembly.
942 Tue Oct 15 20:12:32 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
944 * doc/refcard.tex (sec "Working Files"): consistent metavars and
945 other improvements, due to comments by François Pinard
946 (pinard@iro.umontreal.ca)
948 * doc/gdb.texinfo (appendix "Installing GDB"): changes in
949 configure, and improvenets related to Pinard's refcard comments
951 Tue Oct 15 08:45:12 1991 John Gilmore (gnu at cygnus.com)
953 Changes from Fred Fish:
954 * tm-68k.h (FPI_REGNUM): Add.

976 (nodes Continuing and Stepping; Memory; Targets) clarifications
979 Fri Oct 11 23:27:06 1991 John Gilmore (gnu at cygnus.com)
981 * tm-{irix3,mips,nindy960,pn,symmetry,vx960}.h: Move
982 REGISTER_U_ADDR to corresponding xm- file. Sugg. by Peter Schauer.
984 * symmisc.c (print_partial_symtabs): Add printpsyms debug cmd.
986 * m68k-tdep.c (m68k_push_dummy_frame, m68k_pop_frame): Add
987 generic routines for calling inferior functions.
989 * blockframe.c (inside_main_scope, inside_entry_scope): New.
991 * copying.awk: Filter formfeeds out of copying & warrantee.
992 Make them available as `show copying' and `show warrantee' also.
993 * main.c (print_gnu_advertisement): Advt `show' commands.
995 Thu Oct 10 17:25:47 1991 John Gilmore (gnu at cygnus.com)
997 * mach386-xdep.c: Even when cross-compiling, leave in the
998 core-file reading code.
999 * core.c (get_core_registers): Avoid coredump if no .reg section.
1001 Wed Oct 9 17:03:34 1991 John Gilmore (gnu at cygnus.com)
1003 * mipsread.c, coffread.c: initialise TYPE_VPTR_FIELDNO to -1.
1004 This avoids coredumps under `set print object on' in value_headof
1005 (called erroneously by value_from_vtable_info) for `p &struct'
1006 or `p *struct'. From Peter Schauer.
1008 Mon Oct 7 00:06:52 1991 John Gilmore (gnu at cygnus.com)
1010 * Makefile.in: Roll version to 4.1.2.
1011 * dbxread.c: Use aout64.h, not a.out.gnu.h. Get external symbol entry
1012 size from BFD (but, FIXME, we don't yet read external nlists's and
1013 convert them to internal nlists's before handling them -- we still
1014 assume they have the same size and alignment.) Use SET_NAMESTRING
1016 * exec.c (exec_file_command): Move dead coff-encapsulation code
1018 * m88k-tdep.c, m88k-xdep.c: Remove encap test and #inc <a.out.h>.
1020 Fri Oct 4 22:30:06 1991 John Gilmore (gnu at cygnus.com)
1022 * configure.in, tm-i386v.h, xm-i386v.h: Intel 386 Mach host port.

1025 Fri Oct 4 17:04:31 1991 Per Bothner (bothner at cygnus.com)
1027 More patches from Peter Schauer <pes@regent.e-technik.tu-muenchen.de>:
1028 * mips-xdep.c (store_inferior_registers): Don't try to
1029 write the (pseudo) FP.
1030 * mipsread.c (parse_partial_symbols): Improved algorithm for
1031 setting pst->texthigh.
1033 Fri Oct 4 16:47:32 1991 Roland H. Pesch (pesch at cygnus.com)
1035 * doc/Makefile: make TEXINPUTS include . everywhere
1037 Fri Oct 4 00:35:56 1991 John Gilmore (gnu at cygnus.com)
1039 * coffread.c, dbxread.c, symfile.c, symmisc.c, symtab.h: Remove
1040 vestiges of typevectors, which were for symsegs and are no longer
1041 used. (From a question by Eliot Dresselhaus
1042 <dresselh@RFT30.nas.nasa.gov>).
1044 Thu Oct 3 09:33:26 1991 John Gilmore (gnu at cygnus.com)
1046 * dbxread.c, coffread.c: static-ize functions that were
1047 gratuitiously external. (From Fred Fish.)
1049 * c-exp.y: sym->class to SYMBOL_CLASS (sym).
1051 * dbxread.c (dbx_lookup_type): Keep doubling size of typevector
1052 until it is large enough.
1054 * dbxread.c (read_type): Handle error case slightly better.
1055 Make complaint message not C++-specific.
1057 Wed Oct 2 17:21:07 1991 Stu Grossman (grossman at cygnus.com)
1059 * infrun.c (wait_for_inferior): Fix step/next so that you only
1060 stop at the beginning of a new line. This fixes various problems
1061 with for loops, nested if-else's and switch statements.
1063 Tue Oct 1 06:33:55 1991 John Gilmore (gnu at cygnus.com)
1065 * symtab.c (lookup_symtab_1, lookup_symbol): "fatal" errors
1066 between symtabs and psymtabs become ordinary error()s.
1068 * dbxread.c (read_dbx_symtab): Relocate end_of_text_addr
1069 properly, making "end pc" correct in shared lib psymtabs.
1070 (From Guy Harris <guy@auspex.com>.)
1072 Mon Sep 30 13:15:31 1991 John Gilmore (gnu at cygnus.com)
1074 * dbxread.c: Enable, but soften, const_vol_complaint.
1075 (read_dbx_symtab): N_STSYM and N_LCSYM define static vars.
1076 Ditto Gould N_NBSTS and N_NBLCS. Also, all types in the psymtab
1077 should be file-scope, not global.
1078 (read_struct_type): Remove ancient multiple-inheritance warning.
1079 (read_range_type): Check base type, complain & patch if undefined.
1080 * stack.c (frame_info): Demangle the function name in `info stack'.
1081 (From Peter Schauer)
1083 Sat Sep 28 10:02:33 1991 John Gilmore (gnu at cygnus.com)
1085 * eval.c (evaluate_subexp_for_address): Don't use
1086 TYPE_POINTER_TYPE directly (it might be zero if this type has
1087 never had a pointer created before); use lookup_pointer_type.
1088 * symtab.c (lookup_method_type): Arguments were swapped in all
1089 callers, so fix it here. I'm amazed this worked at all!
1091 Fri Sep 27 18:09:31 1991 John Gilmore (gnu at cygnus.com)
1093 * c-exp.y, m2-exp.y: Define more yysymbols that happen to be
1094 "bss" rather than "data" symbols, but which still conflict.
1097 * coffread.c (coff_symfile_read): Use xmalloc, not malloc.
1098 * core.c (core_files_info): Shorten output.
1099 * exec.c (exec_files_info): Ditto.
1100 (build_section_table): Ignore zero-length sections.
1101 * language.c, printcmd.c: Lint.
1102 * language.h (get_frame_language): Declare.
1103 * saber.suppress: update.
1104 * stack.c (find_relative_frame): Remove complex code that was
1105 #if 0'd, stick with simple code. Lint.
1106 * saber.suppress: Update a bit.
1107 * symfile.c (add_symbol_file_command): Add "?" to question.
1108 * utils.c (parse_escape): Avoid \a due to bdead compilers.
1109 * value.h: Declare typedef_print.
1111 * valprint.c (val_print, type_print_base): TYPE_CODE_RANGE less
1114 * nindy-tdep.c (nindy_frame_chain_valid): Use lookup_misc_func.
1115 (Reported by Mark Peek <mark@imagen.com>.)
1117 * solib.c (solib_map_sections): Relocate all sections, even
1118 though only the text section's size is tracked. Mark ld_text
1119 for eventual elimination as we generalize to N sections.
1121 * infrun.c (wait_for_inferior): Don't check if the PC is in a
1122 call_dummy if we were stopped by a random signal that is being
1123 passed to the program. This produced wierd results when calling
1124 functions in the inferior and signals (e.g. SIGALRM) were in use.
1126 Tue Sep 24 18:05:30 1991 John Gilmore (gnu at cygnus.com)
1128 * infrun.c (IN_SIGTRAMP): Not parenthesized properly.
1129 Bugfix from Paul Eggert <eggert@twinsun.com>.
1130 * tm-ultra3.h (IN_SIGTRAMP): Ditto.
1131 * valprint.c (print_floating): Print 9 digits for IEEE floats.

1140 Fri Sep 20 16:10:52 1991 John Gilmore (gnu at cygnus.com)
1144 * Makefile.in (VERSION): Set to 4.1.
1145 * language.c (set_language_command): Print useful help message,
1146 and restore the language string after giving help.
1147 * valprint.c (typedef_print): Print typedef in C or M2.
1148 * symtab.c (list_symbols): Use it.
1149 * main.c (main): Avoid any output before (gdb) prompt when -q.
1150 * language.c (set_language_command): Handle errors by restoring
1151 the language string to its current state (fix from A. Beers).
1152 * doc/gdbint.texinfo: Roll in information from README. Rearrange
1153 "how to install" and "how to print the doc" stuff so it drops
1155 * configure.in: Rename rtpc CPU to romp to match config.sub.
1156 * README, WHATS.NEW, TODO: Update for gdb-4.1.
1158 Fri Sep 20 17:39:14 1991 Roland H. Pesch (pesch at cygnus.com)

1161 autoloading shared libs, copyright etc on GDB startup, clean up $_
1162 and $__ index refs, set/show listsize and related updates to list
1163 cmd. New host/target configs.
1165 Fri Sep 20 15:46:00 1991 Roland H. Pesch (pesch at cygnus.com)
1167 * doc/Makefile: generate aux version-no file doc/gdbVN.m4
1168 from main Makefile.in version definition
1169 doc/gdb.texinfo: use version recorded in doc/gdbVN.m4 for current
1171 Makefile.in (setup-to-dist): generate doc/gdbVN.m4
1173 * doc/gdb.texinfo: merge new language-switching and lang-specific
1176 Fri Sep 20 15:00:57 1991 Per Bothner (bothner at cygnus.com)
1178 * mcheck.c: Add __ONEFILE kludge to allow compilation by non-ANSI
1179 compilers (which may lack stddef.h).
1181 Fri Sep 20 13:29:42 1991 John Gilmore (gnu at cygnus.com)
1183 * dbxread.c (read_dbx_symtab, process_one_symbol): N_FN and
1184 N_WARNING are the same except for the N_EXT bit, so just use their
1185 values alone, rather than OR-ing them with N_EXT.
1187 Fri Sep 20 12:27:55 1991 Stu Grossman (grossman at cygnus.com)
1189 * mipsread.c (parse_lines): Deal with negative extended line
1192 * c-exp.y, m2-exp.y: #define yyerrflag and yynerrs to avoid
1193 global symbol conflicts.
1195 Fri Sep 20 02:28:15 1991 John Gilmore (gnu at cygnus.com)
1197 * .gdbinit: Move 'set complaints' to top, so it runs even in
1198 case we aren't debugging GDB.
1199 * language.c (_initialize_language): Fix type check and range
1200 check documentation strings.
1201 * utils.c (!HAVE_VPRINTF): Define vfprintf as a function, so
1202 language.c can use it. (Though language.c should really not be
1203 handling warnings/errors the way it does, FIXME.)
1204 * symtab.c (lookup_primitive_type): const lint.
1206 Bugfix from Peter Schauer:
1207 * source.c (lines_to_list): Make signed, to avoid comparison
1208 going unsigned and complaining that -3 is too high for 21 lines.
1209 * stack.c (lines_to_list): Ditto.
1211 Thu Sep 19 23:33:41 1991 John Gilmore (gnu at cygnus.com)
1213 * Makefile.in (HFILES): Add minimon.h.
1214 (VERSION): Roll version number to 4.0.95.
1215 (gdb.tar.Z, make-proto-gdb.dir, setup-to-dist, gdb-XXX.tar.Z):
1216 New rules for building distributions. Normal distribution
1217 is built by doing `make -f Makefile.in gdb.tar.Z' in the directory
1218 one level up from here; it calls make-proto-gdb.dir to build a
1219 directory `proto-gdb' which is an image of the release. The old
1220 `gdb.tar.Z' rule still works too.
1221 * config.sub, configure: Roll in latest from ..
1223 Thu Sep 19 17:41:24 1991 Roland H. Pesch (pesch at cygnus.com)
1225 * doc/gdbint.texinfo: Reorder contents; reorganize new-host,
1226 new-target, and new-config chapters; fix minor typos; come closer
1227 to usual GNU markup conventions for @file @samp @code @var.
1229 Thu Sep 19 17:04:12 1991 Per Bothner (bothner at cygnus.com)
1231 Patches from Peter Schauer <pes@regent.e-technik.tu-muenchen.de>:
1232 * mipsread.c (parse_partial_symbols): Enter the name of all
1233 structs/unions... into the psymtab so we can access them if the
1234 symtab is not read in.
1235 * mips-tdep.c: Remove some unneeded #includes.
1236 * xconfig/dec3100: Add HAVE_STRSTR.
1238 Thu Sep 19 15:14:23 1991 John Gilmore (gnu at cygnus.com)
1240 * Makefile.in: Circumvent Sun Make bug on *-exp.tab.o.
1241 * c-exp.y, m2-exp.y: Lint.
1242 * m2-exp.y: Avoid using yytname[] which is a Bison-ism.
1243 * valprint.c (val_print_fields): Check for stub type.
1244 * mipsread.c (_initialize_mipsread): Avoid using
1245 builtin_type_void at initialize time.
1246 (mipscoff_symfile_read): use it now.
1248 Wed Sep 18 15:55:51 1991 John Gilmore (gnu at cygnus.com)
1250 Merge multiple-language support, and partial Modula-2 support,
1251 from Andrew Beers <beers@cs.buffalo.edu>.
1253 * i387-tdep.c: New file, consolidates most 80387 support,
1254 and eliminates host dependency on double<->extended conversions.
1255 * i386-xdep.c, symm-xdep.c: Remove most 387 support.
1256 * xconfig/i386{sco,v,v-g,v32,v32-g}: Now need i387-tdep.o.
1258 * symfile.c (allocate_symtab): New fn, consolidates the work
1259 of allocating and initializing a new struct symtab. Set the
1260 language of the symtab based on its filename extension.
1261 * symfile.h: Declare it.
1262 * mipsread.c (new_symtab): Use it. Minor formatting changes.
1263 * dbxread.c (end_symtab): Use it.
1265 * mipsread.c (parse_symbol, case stParam and stProc): Add #if 0'd
1266 code for saving types of parameters with each function definition.

1275 * symtab.c (add_param_to_type): #if 0'd function to add a
1276 parameter type to a function type's field list.

1347 Tue Sep 17 08:37:41 1991 John Gilmore (gnu at cygint.cygnus.com)
1349 Add Andrew Beers' changes for Modula-2 support. His ChangeLog
1350 entries are enclosed herein. Not all of these changes
1351 have been merged into the master GDB sources -- check the
1352 ChangeLog above here for the merge log.
1354 Mon Jun 3 17:05:45 EDT 1991
1356 m2-exp.y Created. Tested outside of GDB for a few days. Proper
1357 operators were added, C specific operators and tokens
1358 removed. yylex() revamped to some extent. Still things
1359 missing from the grammar, such as sets.
1360 Tested for two weeks in GDB v3.5.
1362 Tue Jun 11 17:23:48 EDT 1991
1364 m2-exp.y Added boolean constants TRUE and FALSE to the grammar
1365 so they are built-in. Sort of a hack.
1367 Fri Jun 14 12:53:51 EDT 1991
1369 m2-exp.y Added range checking for numeric constants. Any numeric
1370 constant is assumed to be of builtin type INTEGER unless:
1371 (1) it is octal or hexadecimal, in which case it is a
1372 CARDINAL; (2) it is too big to fit into an INTEGER, in
1373 which case it is a CARDINAL.
1374 eval.c Added simple range checking for +, -, and * on integers.
1375 Doesn't work very well for *, since 6 * 1,000,000,000 =
1376 1,705,032,704, which fails the simple test of result >=
1377 first_operand, no matter in what order the operands are.
1379 Tue Jun 18 14:11:30 EDT 1991
1381 Broke the parser into parts, one containing the C grammar and the other
1382 containing code to be shared by all of the grammars.
1384 The following files no longer exist:
1389 The following files were added:
1391 c-exp.y (The C grammar)
1392 m2-exp.y (The Modula-2 grammar)
1393 parser-code.c (Code that is shared by the above grammar)
1397 Makefile.dist Changed to reflect the above dependencies. NOTE: It is
1398 now necessary to use the Bison compiler compiler, since it
1399 will generate function/variable prefixes other than yy.
1401 Tue Jun 18 16:47:49 EDT 1991
1403 symtab.[ch] Added the external variable working_lang, than holds the
1404 value of the current working language.
1405 Added the ennumerated type language_mode, with the values
1406 language_auto and language_manual, the former meaning that
1407 GDB sets working_lang as needed, and the latter meaning
1408 that the value of working_lang is totally under user
1410 symtab.[ch] Added the Modula-2 pervasive types INTEGER, CARDINAL,
1411 REAL, BOOLEAN and CHAR. Also added the type codes
1412 TYPE_CODE_BOOL and TYPE_CODE_CHAR.
1413 utils.c Added set_language_command and show_language_command to
1414 implement the GDB support commands "set language" and
1416 expression.h A number of identifiers were added to the type exp_opcode
1417 to facilitate Modula-2 builtin functions, integer
1418 division, and array indexing.
1420 Wed Jun 19 13:25:58 EDT 1991
1422 language.h Added the macro STRICT_TYPE, which evaluates to non-zero
1423 if the language specified by working_lang requires the use
1424 of strict typing of expressions. Eventually, even this
1425 will be able to be changed by the user.
1426 Added the macro RANGE_CHECK, which evaluates to non-zero
1427 if the language specified by working_lang requires the
1428 checking of a value against the domain of its type.
1429 Eventually, even this will be able to be changed by the
1431 language.[ch] Predicates involving types (simple_type, ordered_type,
1432 same_type, integral_type, numeric_type, character_type,
1433 boolean_type, float_type) are added. These predicates are
1434 based on the current value of working_lang, and are handy
1437 Wed Jun 19 15:39:34 EDT 1991
1439 eval.c Added the function type_array_rank which computes the rank
1441 valarith.c Added the funtion value_bool, which when given a integer
1442 value.h value (ie. struct value *) as an argument, it returns a
1443 boolean value (ie. struct value *) true if that integer
1444 is non-zero, and a boolean value false otherwise.
1445 valprint.c Added cases for TYPE_CODE_BOOL, so Modula-2 BOOLEAN values
1446 will print out properly.
1448 Wed Jun 19 16:36:34 EDT 1991
1450 valops.c Added the function value_capitalize, which returns it
1451 value.h argument capitalized if its argument is a lowercase
1452 letter, or the argument unchanged if its argument is not a
1454 valarith.c Added the function range_check_p, which returns non-zero
1455 value.h if its value argument is between the integral bounds upper
1457 Added the function range_check_enum_p, which makes sure
1458 that its value argument is a valid member of the domain of
1460 Added the function range_check_range_p, which makes sure
1461 its value argument lies between the upper and lower bounds
1462 of its type argument, which must be a ranged type.
1463 Added the function check_array_index, which range and type
1464 checks an index of an array.
1465 Added the function value_multi_subscript, which computes
1466 array[idx1,idx2...idxN], given a value array and an array
1467 of values representing indicies.
1468 values.c Changed value_from_long to work with TYPE_CODE_CHAR and
1469 unpack_long to work with TYPE_CODE_BOOL and
1472 Wed Jun 19 18:04:08 EDT 1991
1474 symtab.c Stored pervasive types in a structure and make
1475 lookup_pervasive_type() a lookup function that was based
1476 on working_lang. If lookup_pervasive_type() returned
1477 non-zero, then that value was returned (a fix, since
1478 before it simply wouldn't return the pervasive type.)
1479 language.h Added the macro CAST_IS_CONVERSION, which evaluates to
1480 non-zero if the language specified by working_lang means
1481 "conversion" when it says "cast".
1482 valops.c Added the function value_real_cast(), which performs a
1483 value.h *cast*, not a *conversion*, which is what value_cast()
1484 does when it can. In particular,
1485 value_cast(<float_type>,4) = 4.0, while
1486 value_real_cast(<float_type>,4) = some mess.
1487 eval.c Modula-2 builtin functions implemented: ABS, CAP, CHR,
1488 parser-code.c FLOAT, HIGH, MAX, MIN, ODD, ORD, TRUNC, and VAL.
1489 expression.h Added macros MAX_OF_TYPE and MIN_OF_TYPE to work with MAX
1490 and MIN on integral types. *NOTE*: These are currently
1491 hardcoded to work only if there are 8 bits per storage
1493 eval.c Made logical functions call value_bool to return a
1494 properly typed boolean value, based on working_lang.
1496 Thu Jun 20 11:55:27 EDT 1991
1498 valprint.c Types now print out in a Modula-2 fashion. This works for
1499 the cases when the type is printed out step-by-step, that
1500 is, it doesn't work when the name of a structured type
1501 (which includes the keyword "struct", etc.) is simply
1503 FIXME: Perhaps this is bad. Parts of it seem to kludgey,
1504 since type specifications in C and Modula-2 are very
1505 different. The C printing of a type is very recursive,
1506 whereas in Modula-2 it is generally very simple. C has
1507 type prefixes and suffixes, which have no real analogue in
1508 Modula-2. Maybe type_print() should call a language
1509 specific type printer. This is also advantageous if we
1510 compile GDB to exclude some of the languages. We'll just
1511 leave those functions out.
1513 Thu Jun 20 16:57:10 EDT 1991
1515 dbxread.c When reading the complete symbol table in (via
1516 psymtab_to_symtab()), the number and types of function
1517 arguments are added to a function type. define_symbol()
1518 calls add_param_to_type() to accomplish this.
1519 Assumption: when we come across a function definition
1520 (N_FUN symbol with an 'f' or 'F' in the name), its
1521 arguments will appear before another function definition.
1522 When a function is found, a pointer to its type is placed
1523 in the global in_function_type. Changes that
1524 add_param_to_type() makes are to this global.
1525 valprint.c The type of a function now includes (for Modula-2) the
1526 types of its parameters.
1527 eval.c Type checking and a check for the proper number of
1528 arguments is now done for function calls. Not sure of the
1529 impact this has on C++ member function yet.
1531 Thu Jun 20 19:58:48 EDT 1991
1533 valprint.c Rewrote the type printer. Broke it into two language
1534 specific parts, adding the functions type_print_m2() and
1536 An unfortunate consequence is this: if you debugging a C
1537 program in Modula-2 mode (why?), info types does not work
1538 well with regular expressions, since the types are printed
1539 out in Modula-2 terminology, but stored in C terminology.
1540 language.[ch] Added the functions new_type_last(), type_keyword(), and
1541 type_sep() to aid in the printing of typedefs.
1542 symtab.c Made the printing of typedefs as language independent as
1543 possible through calls to new_type_last(), type_keyword(),
1546 Fri Jun 21 11:50:26 EDT 1991
1548 dbxread.c Check all incoming ennumerated types. If it looks like
1549 Modula-2's BOOLEAN type, then change the type_code of the
1550 type to TYPE_CODE_BOOL so we can process it as a boolean
1552 valprint.c Replaced some of the 0x%x with calls to sprintf and
1553 hexformat() in val_print().
1554 language.[ch] Added the function hex_to_string(), which converts its
1555 integral argument to a hexadecimal number (format is
1556 language based) and returns the result as a string.
1558 Mon Jun 24 12:25:07 EDT 1991
1560 valprint.c Some functions call type_print_1() directly, instead of
1561 value.h using type_print(), so they can specify where (column) to
1562 print things. Since type_print() takes care of language
1563 dependence, that needs to be called first. Added a
1564 parameter depth to type_print() (so it is now like
1565 type_print_1). Changed type_print to type_print_at, and
1566 made type_print a macro that passes a depth argument of
1568 symmisc.c Changed all calls to type_print_1 to calls to
1570 Makefile.dist Made it possible to build GDB for a specific set of
1571 depend languages. Do this by passing a definition for the macro
1572 LANGS to make. LANGS should be a string containing a
1573 space-separated list of language names (ie. LANGS="c m2").
1574 The default is to build all languages. Note that grammar
1575 files must follow the naming convention of <lang>-exp.y.
1576 gdb.lang This holds the current value of the LANGS macro. It is
1577 examined every time make is called, and is updated if
1579 eval.c Added #ifdef _LANG_<lang> to these files.
1580 expread.c Still need to add them to dbxread.c and coffread.c.
1588 Mon Jun 24 16:33:11 EDT 1991
1590 language.[ch] Added the functions hexformat_pre() and
1591 hex_to_string_pre(), which take a prefix argument to
1592 include in the format string. Thus, hexformat_pre("08") will
1593 return "0x08x" (if the working language is language_c).
1594 Made hexformat() and hex_to_string() calls to the above
1595 with "" as the prefix argument.
1597 am29k-pinsn.c, arm-pinsn.c, breakpoint.c, convex-tdep.c, exec.c, core.c,
1598 dbxread.c, i386-pinsn.c, i386-stub.c, i386-xdep.c, i960-pinsn.c,
1599 infcmd.c, inflow.c, m68k-pinsn.c, m68k-stub.c, m88k-pinsn.c,
1600 mips-pinsn.c, mips-tdep.c, ns32k-pinsn.c, printcmd.c, pyr-pinsn.c,
1601 pyr-tdep.c, pyr-xdep.c, remote-vx.c, remote.c, solib.c, source.c,
1602 stack.c, sun386-xdep.c, symfile.c, symm-xdep.c, symmisc.c, tahoe-pinsn.c,
1603 valprint.c, vax-pinsn.c
1605 Changed all occurences of 0x%[0-9]*l*x in printf format strings to
1606 calls to hexformat() and hex_to_string(). Format strings without
1607 the leading "0x" were ignored.
1609 depend Updated to take the above into account.
1612 Tue Jun 25 15:27:18 EDT 1991
1614 symtab.h Added the types range_mode_t, range_check_t, type_mode_t,
1615 and type_check_t to keep track of the current state of
1616 range and type checking.
1617 main.c Added the variables range_mode, range_check, type_mode,
1618 and type_check to record the current state of range and
1619 type checking. Added initialization code to main().
1620 language.h Changed the macros STRICT_TYPE and RANGE_CHECK to examine
1621 the above variables.
1624 Tue Jun 25 17:57:08 EDT 1991
1626 dbxread.c process_one_symbol() updates the variable (enum language)
1627 source_lang based on the extension of the filename
1628 contained in the N_SO sybmol that started this symtab.
1629 When end_symtab() is called, the value of source_lang is
1630 put into the language field.
1631 stack.c select_frame() sets working_lang (and possibly type_check
1632 and range_check) to the language field of the symtab
1633 associated with the frame that is selected if working_mode
1634 is language_auto. If working_mode is language_manual, a
1635 warning is printed and working_lang is not set.
1636 language.c Added the function set_type_range(), which sets the value of
1637 type_check and range_check (if their modes call for
1638 automatic setting) based on the current value of
1639 working_lang. A non-zero argument will cause the current
1640 settings to be output.
1643 Wed Jun 26 14:51:40 EDT 1991
1645 eval.c Added range checks on assignment.
1646 m2-exp.y Added the grammar for sets to the language. Currently,
1647 these do not do anything except print an error message.
1649 Wed Jun 26 17:01:04 EDT 1991
1651 m2-exp.y Added the ability for parse_number() to parse negative
1652 numbers. A global flag is set upon encountering a unary
1653 minus. This was done to make, for example, 1 parse as a
1654 CARDINAL, and not as an integer, per Wirth's examples in
1655 Programming in Modula-2 ed.4.
1656 valprint.c Added support for "set radix 2" by then setting
1657 output_format to 't'.
1658 eval.c Implemented range checking on subrange types. Added calls
1659 to range_check_range_p for BINOP_ASSIGN and BINOP_VAL.
1660 Implemented MIN and MAX for ennumerated types. The
1661 minimum value of an ennumerated type is defined by Wirth
1662 as the first identifier, and the maximum as the last.
1663 m2-exp.y Made octal numbers ending with "B" be characters and those
1664 ending with "C" be numbers, per Wirth's book. (p. 34)
1666 Thu Jun 27 14:11:52 EDT 1991
1668 stack.c select_frame() now only sets working_lang, it does not
1669 notify the user. If working_mode is language_manual, then
1670 a warning is issued once.
1671 main.c At the end of each call to execute_command(), working_lang
1672 is checked against the local static (enum language)
1673 current. If they differ and working_mode is
1674 language_auto, the new settings of language, type and
1675 range checking are printed out.
1676 stack.c Modified frame_info() to include the language of the
1677 current frame in the output of "info frame".
1678 language.[ch] Added the function language_str() which returns the name
1679 of the current language.
1681 Fri Jun 28 15:33:14 EDT 1991
1683 m2-exp.y Added the built-in procedures INC, INCL, DEC, and DECL to
1684 the language. INCL and DECL currently cause an error,
1685 since sets are not implemented yet. INC and DEC are
1686 implemented as PREINCREMENT/PREDECREMENT with one
1687 argument, and as ASSIGN_MODIFY with two arguments.
1688 eval.c Added type checking to the above cases.
1689 value.h Added not_lval_constant to the lval_type ennumerated type.
1690 not_lval_constant means that the value is a constant
1691 value; that is 3 or 'a' or TRUE, not as in a constant
1692 identifier. This is used to help coerce numbers such as 3
1693 to either signed or unsigned numbers.
1694 valops.c Added the function value_coerce_constants() which coerces
1695 constant integers as following: if one is a constant and
1696 the other is not, the constant's type is set to the type
1697 of the other argument. If both are constants and one is
1698 signed, the other is converted to a signed constant.
1700 Sat Jun 29 17:26:29 EDT 1991
1702 valarith.c Added a better range checker. It now checks range
1703 (successfully) on integral operations [+-] (signed and
1704 unsigned) for any C sized type. Still does not work well
1705 for multiplication.)
1706 int_in_size() returns an integer that is coerced to fit into
1707 specified number of bytes.
1709 Mon Jul 1 13:04:14 EDT 1991
1711 language.[ch] Added the function binop_result_type(), which returns the
1712 builtin (struct type *) type that would be the result of a
1713 binop on the two values V1 and V2.
1715 Wed Jul 3 19:22:53 EDT 1991
1717 source.c Extended source_info() to include the source language in
1718 the output from "info source".
1720 Fri Jul 5 13:48:52 EDT 1991
1722 utils.c Moved the support functions for the GDB set/show commands
1723 dealing with language into language.c.
1724 language.c Added the function language_info(), which displays info
1725 about the current working language, type and range check
1726 settings. Called via the GDB command "info language".
1727 Added an initialization routine _initialize_language(),
1728 that sets defaults for the language, type and range
1729 variables and sets up the new GDB commands.
1730 main.c Language setup moved to language.c.
1733 Mon Jul 8 10:10:22 EDT 1991
1735 valarith.c Debugged the range checker for arithmetic. Still does not
1736 work for multiplication very well.
1738 Mon Jul 8 12:40:37 EDT 1991
1740 language.[ch] Added the function value_true() which returns non-zero if
1741 its argument represents a boolean true value.
1742 breakpoint.c Changed breakpoint_cond_eval() to call value_true() to
1743 check the truth of an expression.
1745 Thu Jul 11 12:51:34 EDT 1991
1747 language.[ch] Added the predicate structured_type(), which returns
1748 non-zero if the argument is a structured type.
1749 Added the predicate pointer_type(), which returns non-zero
1750 if the argument is a pointer type.
1751 eval.c Added the ability to do addition and substraction on
1752 pointers and integers. This case simply bypasses the
1755 Thu Jul 11 14:41:42 EDT 1991
1758 Added the symbol N_DEFD (0x4a) which is a definition
1759 module dependency that is used by the GNU Modula-2
1760 compiler and the linker. It is not important to GDB,
1761 except that [dbx|coff|mips]read.c should ignore these
1764 Fri Jul 12 16:07:00 EDT 1991
1766 valprint.c Changed the TYPE_LENGTH(type) >= 0 to TYPE_LENGTH(type) >
1767 0 in val_print(). Also added statements to the else part
1768 to coerce type (argument to val_print) to a pointer type
1769 if it is an "array of unspecified length".
1770 valops.c Added the function value_m2_string(), which returns a
1771 (value) value which is a constant string, whose type is
1772 (ARRAY [0..n] OF CHAR). The length field of the type
1773 structure is set to zero, so it will be interpreted as an
1774 "array of unspecified length".
1775 stack.c Moved the language/frame mismatch check to
1776 main.c:execute_command().
1777 main.c The working language is recorded each time
1778 execute_command() is executed. If working lang has
1779 changed during its execution, then the new
1780 language/type/range info is printed out for the user. If
1781 the working language does not match the language of the
1782 frame, a warning is issued.
1784 Sat Jul 13 16:16:39 EDT 1991
1786 eval.c Moved all the type-checking stuff for operators to
1787 language.[ch] language.c. This is so we can keep language-specific
1788 stuff (like for what type operators are defined) in
1790 language.[ch] Added the function binop_type_check(), which checks to see
1791 if its two (value) arguments are type-compatible with its
1792 opcode argument. The opcode should represent an operation
1793 involving an operator. Also added the macro function
1794 unop_type_check, which calls binop_type_check with a
1795 NULL second argument.
1796 expprint.c Added Modula-2 operators to the op_print_tab, so info
1797 expression.h break works correctly. Also added "op_string", which
1798 returns the string corresponding to the (enum exp_opcode)
1799 opcode that is its argument.
1802 Sat Jul 13 18:26:18 EDT 1991
1804 coffread.c Added code to record the type of function arguments with
1805 each paricular function. Code is very similar to that
1807 dbxread.c Moved add_param_to_type() to symtab.c
1808 symtab.[ch] Added function add_param_to_type() from dbxread.c
1810 *** NOTE: The above additions have not been tested.
1812 Mon Jul 15 12:50:47 EDT 1991
1814 langauge.[ch] Added the functions type_error and range_error, which work
1815 like error() except if the type/range mode is set to
1816 *_mode_warn, then they do not do a return_to_top_level(),
1817 but merely print a warning.
1818 Also changed [set|show]_[type|range]_command() to support
1819 the new "warn" feature.
1821 Thu Jul 18 17:50:54 EDT 1991
1823 mipsread.c Added code to record the type of function arguments with
1824 each particular function. Code is very similar to that
1827 *** NOTE: The above additions have not been tested.
1829 Fri Jul 19 11:19:10 EDT 1991
1831 defs.h Added macros MAX_OF_SIZE, MIN_OF_SIZE, UMAX_OF_SIZE, and
1832 UMIN_OF_SIZE, which when given a size of a numeric type,
1833 return the maximum and minimum value it can hold. UMAX...
1834 and UMIN... return the result for unsigned types.
1835 symtab.h Added the macros MAX_OF_TYPE and MIN_OF_TYPE to operate on
1836 struct types. They call above macros.
1837 dbxread.c Renamed the MAX and MIN_OF_TYPE macros to ..._OF_CTYPE to
1838 avoid a name conlict with the above.
1839 c-exp.y Added range checking on numeric constants in
1840 parse_number() for completeness.
1841 valarith.c Made binop_user_defined_p() and unop_user_defined_p()
1842 return 0 if working_lang is not language_c.
1844 Thu Aug 8 14:17:22 EDT 1991
1848 breakpoint.c Documentation strings of some commands changed to
1849 eliminate the references to the C language where
1852 Tue Aug 13 15:48:03 EDT 1991
1854 m2-exp.y Added qualified identifiers to the grammar. The semantics
1855 are slightly different from those of the GDB operator ::
1857 m2-exp.y Added a rule to each grammar of the form: start ::= exp |
1858 type_exp, where type_exp is any valid type expression.
1860 eval.c Added the opcode OP_TYPE, and an error case in eval.c.
1861 printcmd.c Modified ptype_command() so it actually parses the input
1862 (necessary for type expressions with scope qualifiers).
1863 Added the function ptype_eval() which expects an
1864 expression composed of one OP_TYPE element.
1865 *.[ch] Replaced all occurences of parse_c_expression with
1867 *.[ch] Replaced all occurences of parse_c_1 with parse_exp_1
1869 [End of ChangeLog entries from Andrew Beers for Modula-2 support.]
1871 Mon Sep 16 17:19:46 1991 John Gilmore (gnu at cygnus.com)
1873 Small fixes from Peter Schauer:
1875 * infrun.c (child_attach): Lint.
1876 * solib.c (find_solib): Handle shared libs version 2.
1878 Small fixes from David Wood:
1880 * xm-ultra3.h (SYS_SIGLIST_MISSING): Typo.
1884 * remote-vx.c: Move <stdio.h> to top, for FILE. Fix from
1885 John S <basrai%kanga.dnet@c3po.sm-alc.af.mil>.
1887 * utils.c (wrap_here): Avoid wrap action of fputs_filtered if
1888 chars_per_line is at maximum (user typed `set width 0'). Fix
1889 from Andreas Schwab <schwab@ls5.informatik.uni-dortmund.de>.
1891 Tue Sep 17 17:31:04 1991 Stu Grossman (grossman at cygnus.com)
1893 * coredep.c: include ptrace.h where necessary.
1894 * mipsread.c(parse_lines): fix unsigned char problem that was
1895 messing up line numbers on SGI's and possibly other MIPS based
1897 * infrun.c (child_create_inferior): use better test to check
1898 return val from setpgrp().
1899 * tm-irix3.h, xm-irix3.h, tconfig/irix3, xconfig/irix3: add these
1900 for sgi/irix support.
1902 Wed Sep 18 04:33:31 1991 Per Bothner (bothner at cygnus.com)
1904 * mipsread.c (parse_symbol): Put non-static procedures
1905 in the global block.
1907 Fri Sep 13 00:14:52 1991 John Gilmore (gnu at cygnus.com)
1909 Patch together `text_start' and `text_end' for 29K port.
1911 * exec.c (exec_command): If NEED_TEXT_START_END, define the
1912 variables and set them based on the exec file.
1913 * am29k-tdep.c: declare text_start.
1914 * valops.c (call_function_by_hand): declare text_end.
1916 * inferior.h: Eliminate CANNOT_EXECUTE_STACK in favor of
1917 defining CALL_DUMMY_LOCATION as BEFORE_TEXT_END. This is
1918 because machines that do this will also have to know to
1919 set NEED_TEXT_START_END. Besides, it was a redundant way to
1921 * tm-29k.h, tm-convex.h, tm-np1.h: Eliminate
1922 CANNOT_EXECUTE_STACK, define CALL_DUMMY_LOCATION and
1923 NEED_TEXT_START_END.
1925 Thu Sep 12 00:22:24 1991 John Gilmore (gnu at cygint.cygnus.com)
1927 AMD 29000 changes from David Wood <wood@david.ultra.nyu.edu>:
1929 * Makefile.in (CLIBS): Put XM_CLIBS and TM_CLIBS at end.
1930 Pass MUNCH_DEFINE to munch whenever we run it.
1931 * am29k-pinsn.c (print_insn): Handle NOP specially. Avoid %#x
1932 format string; use 0x%x instead.
1933 * am29k-tdep.c: Use DUMMY_SAVE_GREGS and RETURN_REGNUM.
1934 * ultra-xdep.c, xm-ultra.h: New files for Ultracomputer host system.
1935 * xm-rtbsd.h: New host support for RT/PC running BSD Unix.
1936 * inflow.c: Handle `short' process group IDs.
1937 * infptrace.c (fetch_register): Support CANNOT_FETCH_REGISTER,

1940 (coff_symfile_init): Initialize text_bfd_scnum.
1941 (read_coff_symtab): Use it to find the text [and absolute?] sections.
1942 * ../config.sub: Add vendor nyu and os "sym[1-9]*".
1943 * configure.in: Add hosts rtpc-*-* and a29k-*-*.
1944 Merge target arm case with other "easy" cases. Add target
1945 cases a29k-*-none (rehack of am29k), a29k-*-kern (remote to
1946 Ultracomputer kernel), and a29k-*-sym1 (ultracomputer OS's user
1948 * minimon.h, remote-adapt.c, remote-mm.c: Add.
1949 * munch: Cope with RT/PC putting fns in data segment.
1950 Restore ability to override `nm' by specifying MUNCH_NM.
1951 * xconfig/rtbsd, xconfig/ultra3: New host systems.
1952 * tconfig/a29k: Rename from tconfig/am29k. Add remote-mm
1953 and remote-adapt. Remove encapsulated coff #define's (the
1954 support should go in BFD, and gdb shouldn't know or care).
1955 * tconfig/a29k-kern: Same, but for remote kernel debugging.
1956 * tconfig/ultra3: For debugging user processes on Ultra3/Sym1.
1957 * tm-29k.h: Update BADMAG (though it should go away).
1958 Allow the register definitions to be overridden in another
1959 tm-file. Fix SR_REGNUM. Add a mess of _REGNUM's. Separate
1960 RETURN_REGNUM from GR96_REGNUM and DUMMY_SAVE_GREGS from
1961 DUMMY_SAVE_GR96, for handling kernel calling conventions
1962 that use GR64+ rather than GR96+.
1963 * tm-ultra3.h: New file, for use on Ultra3 Unix as well as for
1964 remote debugging of Ultra3 kernel. Includes tm-29k.h and
1965 overrides various things.
1967 * remote-mm.c (mm_attach, mm_wait): Handle attach like
1968 child_attach does, making a clean stop in the newly attached
1970 * remote-eb.c: Lint.
1972 * coffread.c: Make coffread independent of any particular
1973 variant of COFF. Avoid #include-ing any particular one except
1974 internalcoff.h. BFD now passes key values for symbol reading
1975 as part of its coff_data structure (LINESZ, SYMESZ, AUXESZ,
1976 and the symbol masks and shifts); use them.
1977 Remove obsolete end_of_text_addr.
1979 * exec.c: Remove unused include files.
1981 Wed Sep 11 19:38:44 1991 John Gilmore (gnu at cygint.cygnus.com)
1983 * Makefile.in (documentation targets): Pass $(M4).
1984 Bugfix from eggert@twinsun.com (Paul Eggert).
1986 * stack.c (down_silently_command): Check for stack existence.
1988 Tue Sep 10 23:08:29 1991 John Gilmore (gnu at cygint.cygnus.com)
1990 * Makefile.in (VERSION): Update to 4.0.3.
1992 Tue Sep 10 09:19:29 1991 John Gilmore (gnu at cygint.cygnus.com)
1994 * core.c (core_file_command): Print frame at coredump with
1995 its level number, by calling print_stack_frame.
1996 * frame.h: Add selected_frame_level, print_stack_frame.
1997 * frame.h, stack.c: Remove print_sel_frame, print_selected_frame.
1998 * convex-tdep.c, convex-xdep.c, infcmd.c, inflow.c, infrun.c:
1999 Change print_sel_frame and print_selected_frame callers to
2002 * dbxread.c (read_ofile_symtab): Avoid empty else clause.
2003 * symfile.c (free_named_symtabs): Ditto.
2004 * main.c (main): wrap_here needs an arg.
2005 * solib.c (find_solib): Avoid memory access if _DYNAMIC is zero.
2006 (solib_add): Avoid noise.
2007 (solib_create_inferior_hook): Lint.
2008 (sharedlibrary_command): Move dont_repeat to here.
2009 * utils.c (error): Call wrap_here to force buffered output.
2011 Small patches from Peter Schauer:
2013 * coffread.c (start_symtab): Free any existing line_vector before
2015 (read_coff_symtab): Ditto for type_vector.
2017 * source.c (lines_to_list): New variable, replacing function.
2018 (all uses): Use as variable.
2019 (_initialize_source): Add 'set listsize' and 'show listsize'.
2020 * utils.c (lines_to_list): Remove function.
2021 * stack.c (print_frame_info): Use as variable.
2022 * defs.h (lines_to_list): Remove declaration.
2024 Mon Sep 9 13:45:57 1991 John Gilmore (gnu at cygint.cygnus.com)
2026 * breakpoint.c (insert_breakpoints): Restore warning about
2027 the program might be running in another process, but only for
2028 systems with this brain death (#ifdef ONE_PROCESS_WRITETEXT).
2029 * xm-hp300bsd.h, xm-mips.h, xm-vax.h: Define it.
2031 * utils.c (error): if error_pre_print is set, print the string
2033 * main.c (main, print_gnu_advertisement, print_gdb_version):
2034 Reformat legalese so it always prints, but acts as an "I'm here"
2035 message while symbols are being read. If any errors occur,
2036 print a few newlines to set off the message and start it at the
2037 left margin. Remove mention of "help" command, and don't yak
2038 about symbol reading.
2039 (catch_errors): Error string is now printed first in case of
2041 * command.c (undef_cmd_error, lookup_cmd): On undefined command,
2042 suggest the "help" command.
2044 * Makefile.in (VERSION): Set to 4.0.2.
2046 Thu Sep 5 23:49:48 1991 John Gilmore (gnu at cygint.cygnus.com)
2048 * .gdbinit: Remove useless "rr" command. Set complaints
2049 to 1 for people debugging gdb.
2051 * breakpoint.c, remote-vx.c: Reword strings printed by
2052 catch_errors callers.
2054 Wed Sep 4 11:07:50 1991 John Gilmore (gnu at cygint.cygnus.com)
2056 * WHATS.NEW: "history write -> history save". Doc "write on/off".
2057 (Fix from kenc@viewlogic.com.)
2059 Fix some infrastructure to be able to cope with host and target
2060 machines with different sized basic types (ints, ptrs, etc).
2061 (Idea from pierre@la.tce.com (Pierre Willard).)
2063 * values.c (value_from_longest): Rename from value_from_long.
2064 Handle pointer types as well as integers, so that targets with
2065 different pointer sizes from the host can be accomodated.
2066 * breakpoint.c, convex-tdep.c, eval.c, expprint.c, printcmd.c,
2067 valarith.c, valops.c, valprint.c, value.h, values.c: Rename
2068 uses of value_from_long to value_from_longest.
2069 * eval.c, findvar.c, printcmd.c, valarith.c, valops.c: Pass
2070 the correct pointer type to value_from_long{est}.
2072 * doc/gdb.texinfo ($_, $__): Describe types of these variables.
2074 * remote-vx.c: Remove obsolete code for calling functions via
2075 vxworks kludge interface (it referenced value_from_long).
2077 * valops.c (value_string): Find malloc with lookup_misc_func, not
2080 Tue Sep 3 18:37:46 1991 John Gilmore (gnu at cygint.cygnus.com)
2082 Make writing to files work properly. (Fixes to BFD are also needed.)
2084 * core.c (core_open): Open file ourselves, read or r/w, depending on
2085 write_files. Use bfd_fdopenr.
2086 * gdbcore.h (write_files): New variable.
2087 * exec.c (write_files): Define variable, add set&show for it.
2088 (exec_file_command): Use write_files to open for read or r/write.
2090 Make shared library reading happen automatically. These changes
2091 are mostly from Peter Schauer <pes@regent.e-technik.tu-muenchen.de>.
2093 * inferior.h (stop_soon_quietly): Add to exported variables.
2094 * infrun.c (child_create_inferior): call solib hook, if defined.
2095 (child_attach): call solib hook, if defined.
2096 * solib.c: Include inferior.h. Add from_tty to so_list as kludge.
2097 (find_solib): Use lookup_misc_func rather than hand-rolled.
2098 (symbol_add_stub): New stub for catch_errors.
2099 (solib_add): Avoid output if !from_tty. Catch errors rather
2100 than just calling symbol_file_add and bombing.
2101 (solib_create_inferior_hook): Interface with the target process
2102 to let it read and alloc shared libs, then figure out what it did.
2104 * core.c (validate_files): Fix typo, soften warning.
2105 (Fix from Hiroto Kagotani <kagotani@cs.titech.ac.jp>.)
2107 * utils.c (fputs_demangled): Avoid duplicate printing if
2108 demangling is off. (Fix from J.T. Conklin <jtc@cayenne.com>.)
2110 * infrun.c (proceed): Cast -1 to (CORE_ADDR) before comparing.
2111 (Fix from pierre@la.tce.com (Pierre Willard).)
2113 * main.c (catch_errors): Change argument to a char * from an int,
2114 since a char * can point to a struct full of glop, but an int
2115 is not guaranteed to be able to hold a pointer.
2116 * breakpoint.c (breakpoint_cond_eval, bpstat_stop_status,
2117 breakpoint_re_set_one, breakpoint_re_set): Adapt.
2118 * core.c (core_open, solib_add_stub): Adapt.
2119 * remote-vx.c (symbol_stub, add_symbol_stub, callers): Adapt.
2121 Wed Aug 28 18:18:05 1991 John Gilmore (gnu at cygint.cygnus.com)
2123 * Makefile.in: Update VERSION to 4.0.1. Evade GNU Make bug
2124 by adding .NOEXPORT target.
2126 Fri Aug 23 17:14:25 1991 John Gilmore (gnu at cygint.cygnus.com)
2130 * Makefile.in (VERSION): Roll to 4.0.
2131 (gdb.tar.Z): Make refcard.ps as well, for shipment.
2133 Fri Aug 23 14:07:09 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
2135 * doc/gdb.texinfo: minor rewordings, crossref to ptype from print,
2138 * doc/Makefile, Makefile.in: generate "gdb-all.texi" rather than
2141 * doc/rdl-apps.texi: renamed from rdl-apps.texinfo
2143 * Makefile.in, doc/Makefile, doc/.Sanitize, doc/gdb.texinfo:
2144 reflect above name change
2146 * WHATS.NEW: correct pointer to refcard.
2148 * doc/gdb.texinfo: update New Features, Installing
2150 * doc/gdbint.texinfo: add short description of configure +template
2152 Fri Aug 23 11:46:08 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
2154 * doc/gdb.texinfo: update, fix bugs in "Installing" appendix
2156 Fri Aug 23 01:02:00 1991 John Gilmore (gnu at cygint.cygnus.com)
2158 * Makefile.in: Add config.sub, make doc/rdl-apps.texinfo for
2159 tar file, add dependencies for referenced doc files.
2161 Thu Aug 22 22:17:06 1991 Stu Grossman (grossman at cygint.cygnus.com)
2163 * coffread.c, symfile.c, stack.c: saberized.
2165 Thu Aug 22 16:20:27 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
2167 * doc/refcard.tex: permuted Essential Commands sec
2169 * doc/gdb.texinfo: new C++ chapter; revised installation appendix;
2171 set/show symbol-reloading
2172 default set complaints 0
2174 RET-repeat disabled after prompted long displays
2175 processID (attach) interpretation of 2nd GDB cmdline arg
2177 Thu Aug 22 14:05:47 1991 Stu Grossman (grossman at cygint.cygnus.com)
2179 * expread.y, coffread.c, dbxread.c, target.c, mem-break.c,
2180 cplus-dem.c, values.c, valprint.c, symfile.c, remote.c,
2181 breakpoint.c, main.c: lint.
2183 Thu Aug 22 02:02:26 1991 John Gilmore (gnu at cygint.cygnus.com)
2185 Install new configuration scheme for GDB and friends.
2187 * config.sub: Translate ordinary names to three-part names.
2188 * configure: Use three-part names internally.
2189 * configure.in: Translate three-part names to filenames.
2191 * README, WHATS.NEW: Update for gdb-4.0.
2192 * Makefile.in: Roll VERSION to 3.99.
2194 Wed Aug 21 18:21:09 1991 John Gilmore (gnu at cygint.cygnus.com)
2196 * infptrace.c (KERNEL_U_ADDR_BSD): Include a.out.gnu.h.
2197 * i960-tdep.c, m68k-tdep.c, sparc-tdep.c, tm-i960.h,
2198 tm-m68k.h, remote-nindy.c: Change ext_format_XXX structs
2199 to single structures rather than arrays; when passing
2200 their address, use &. This avoids trouble with bdead compilers.
2201 * mcheck.c: Don't include <stdlib.h>; just declare "void abort();"
2202 instead. This avoids portability headaches.
2203 * mips-tdep.c (mips_do_registers_info): Only print FP regs if
2205 * source.c (open_source_file): Avoid ANSI const bdeath by
2206 skipping declaration and then casting result value.
2207 * tm-hp300bsd.h: Clarify comment.
2208 * utils.c (strstr): Result is const char *; ANSI bdeath.
2209 * xm-hp300bsd.h: Define HOST_BYTE_ORDER. Redefine INT_MIN,
2210 since system include file defines it differently from "defs.h",
2211 though the two are equivalent for our purposes.
2212 * tconfig/hp300bsd: Add m68k-tdep.o.
2214 Tue Aug 20 16:01:11 1991 John Gilmore (gnu at cygint.cygnus.com)
2216 * tconfig/sun*4: Remove warnings about system assembler.
2218 Mon Aug 19 13:44:46 1991 John Gilmore (gnu at cygint.cygnus.com)
2220 * mcheck.c: Avoid warning about undeclared abort fn.
2221 * tm-sparc.h (PC_ADJUST): Avoid calling error() from this;
2222 it causes recursive calls to error() when used in cleanups.
2223 To do so requires that we make it a function, so we do.
2224 * sparc-tdep.c (sparc_pc_adjust): New implem of PC_ADJUST.
2225 * utils.c (do_cleanups): Remove the current cleanup from the
2226 chain *before* calling it, in case error() is called from it.
2227 The result won't be pretty, but won't be an infinite loop either.
2229 Mon Aug 19 00:41:04 1991 Michael Tiemann (tiemann at cygint.cygnus.com)
2231 * dbxread.c (read_struct_type): Grok anon structs for C++.
2232 (vb_name, vptr_name): Null terminate these strings.
2234 Fri Aug 16 08:31:03 1991 John Gilmore (gnu at cygint.cygnus.com)
2236 Minor bug fixes from BSD Net2 gdb:
2238 * blockframe.c (get_prev_frame_info): If FRAME_CHAIN_COMBINE
2239 returns 0, there is no previous frame.
2240 * breakpoint.c (commands_command): If !from_tty, don't call
2241 input_from_terminal_p().
2242 * dbxread.c (record_misc_function): Speed up slightly.
2243 (compare_psymbols): Ditto.
2244 * infcmd.c (do_registers_info): Take a second argument to
2245 determine whether to print float registers. "info registers"
2246 does not do so anymore. "info all-registers" does, now.
2247 * mips-tdep.c, pyr-tdep.c (xxx_do_registers_info): Take second
2249 * tm-mips.h, tm-pyr.h (DO_REGISTERS_INFO): Pass second arg.
2250 * inflow.c (initialize_inflow): Set tflags_ours correctly.
2254 * breakpoint.c (bpstat_do_actions): Use a cleanup to restore
2255 executing_breakpoint_commands if we are interrupted by error.
2256 * coffread.c (init_lineno): Avoid problem with zero-sized linetab
2257 versus malloc/free. From: john@labtam.labtam.oz.au (John Carey).
2258 * core.c (solib_add_stub, core_open): Call SOLIB_ADD inside a
2259 catch_errors() so we can setup the frame regardless of whether
2260 the shared libs work.
2261 * ieee-float.c (double_to_ieee_extended): Get exponent from
2262 right place in little-endian systems. From John Carey.
2264 Thu Aug 15 18:43:57 1991 John Gilmore (gnu at cygint.cygnus.com)
2266 * main.c: Remove unused terminating_signals and catch_termination().
2267 (long_options): Terminate with a zero element.
2268 [Bugfix from Atsuo Kawaguchi <atsuo@hark86.harl.hitachi.co.jp>.]
2269 (gdb_readline): Make call-compatible with readline.
2270 (init_signals): Improve comments re vfork vs. signal.
2272 * utils.c (prompt_for_continue): Use new gdb_readline().
2273 If we prompt for continuation, we don't let CR repeat the previous
2274 command, once we get back to a prompt. It's too easy to keep
2275 hitting CR, expecting "--more--" prompts, and have some long
2276 command start repeating on you.
2278 Tue Aug 13 16:17:56 1991 John Gilmore (gnu at cygint.cygnus.com)
2280 * blockframe.c (frameless_look_for_prologue): Speed up by
2281 calling SKIP_PROLOGUE_FRAMELESS_P if it's defined.
2282 * tm-sparc.h (SKIP_PROLOGUE, SKIP_PROLOGUE_FRAMELESS_P):
2283 Define two variants, one faster.
2284 * sparc-tdep.c (sparc_frame_chain): Use target_read_memory
2285 and return zero, rather than giving an error.
2286 (setup_arbitrary_frame): Initialize the PC in the new frame.
2287 (skip_prologue): Add a second arg saying whether we're just
2288 checking for a frameless function or not.
2290 * core.c (core_open, core_close, core_xfer_memory): Move
2291 section table pointers and bfd* into the target_ops.
2292 (core_open): Allow errors in shared lib reading, etc.
2293 (core_files_info): Describe shared library sections.
2295 * exec.c (exec_open, exec_close, exec_xfer_memory, xfer_memory,
2296 exec_files_info, set_section_command): Move section table
2297 pointers and bfd* into the target_ops.
2298 (add_to_section_table): Add BFD to section table.
2300 * target.c (target_xfer_memory, target_info): Pass target to
2301 xfer_memory and target_info functions.
2304 * gdbcore.h: Move struct section_table.
2305 * target.h: New home of struct section_table.
2307 * solib.c (solib_add): New argument is the target_ops whose
2308 section list is to be added to, if any. Reallocate the
2309 sections in that target to add any that come from shared libs.
2310 (throughout) so_sections renamed to sections.
2311 (solib_xfer_memory): Deleted.
2312 * tm-sunos.h (SOLIB_ADD): Add target argument.
2313 (SOLIB_XFER_MEMORY): Delete.
2315 * core.c, exec.c, inftarg.c, remote-eb.c, remote-nindy.c,
2316 remote-vx.c, remote.c, target.c, target.h: Remove add_syms vector
2317 from target_ops. It's the same on all targets. Add two section
2318 pointers to target_ops.
2320 * stack.c (find_relative_frame): Dump ancient algorithm for
2321 "down", just use handy "next" pointers.
2322 (frame_command): Don't error if there is no stack; let user
2325 * inflow.c (new_tty_prefork, new_tty): New prefork routine
2326 modifies static state in the parent process; new_tty itself
2327 runs in the child and modifies the child's file descriptors
2328 to match the saved static state.
2329 * infrun.c (child_create_inferior): Call new_tty_prefork,
2332 * infptrace.c (child_xfer_memory): Add ignored target arg.
2333 * remote-eb.c (eb_xfer_inferior_memory): ''
2334 * remote-nindy.c (nindy_xfer_inferior_memory): ''
2335 * remote-vx.c (vx_xfer_memory): ''
2336 * remote.c (remote_xfer_memory): ''. Rename from
2337 remote_xfer_inferior_memory.
2339 * main.c (main): Only try to attach "corefile" argument if
2340 it starts with a digit.
2342 * symfile.c (symbol_reloading): New "set/show" variable.
2343 (symbol_file_add): Shorten message about symbol reading.
2344 (add_symbol_file_command): Merge with add_syms_addr_command,
2345 since this should work on all targets now.
2346 (stop_whining): Default to zero, to shut up complaints
2347 about bad symbol tables on many systems.
2348 (free_named_symtabs): Just exit unless symbol_reloading.
2350 * xm-sun3os4.h, xm-sun4os4.h: Define BROKEN_LARGE_ALLOCA,
2351 and add comment explaining shared library screw.
2353 * source.c: #if defined => #ifdef.
2355 Thu Aug 8 12:23:19 1991 John Gilmore (gnu at cygint.cygnus.com)
2357 * doc/gdbint.texinfo: Improve doc on porting to new OS's.
2359 Tue Aug 6 17:16:15 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
2361 * doc/rdl-apps.texinfo: provide default readline-appendix finder
2362 (doc/Makefile knows how to make one for local config)
2364 * Makefile.in: use doc/Makefile for doc targets
2366 * doc/Makefile: GDB documentation now has its own Makefile
2367 doc/refcard.tex: renamed from "gdbrc.tex"
2368 doc/.Sanitize: add Makefile; recognize renamed refcard.tex
2369 doc/gdbint.texinfo: add markup in "Cleanups" chapter
2372 Fri Aug 2 00:13:06 1991 John Gilmore (gnu at cygint.cygnus.com)
2374 * values.c (baseclass_addr): When reading target memory, use the
2375 length of the basetype, not the upper type. We've only malloc'd
2376 enough space for the basetype, leading to errors in free().
2378 * expprint.c (print_subexp): Print UNOP_MEMVAL of an OP_LONG that
2379 ends up as a function specially, since we know the actual type of
2380 the pointed-to address. This (somewhat) fixes display of
2381 expressions that include misc_function_vector names. Try `cond 1
2382 !strcmp("a","b")' then `i b'.
2384 * infrun.c: Move DO_DEFERRED_STORES from proceed() to resume().
2385 The child can be proceeded from inside wait_for_inferior in
2386 evaluating breakpoint conditions, and DO_DEFERRED_STORES was
2387 getting skipped in that case.
2389 * expprint.c (print_subexp): Use filtered output, since the
2390 subroutines we call use it, otherwise the output is horribly
2391 mangled, since output of wrappable stuff comes out late.
2393 * Makefile.in: Bump VERSION to 3.98.1
2395 * infrun.c (child_create_process): Use execlp to find the
2396 shell to exec our target program. This requires some fiddling
2397 with `environ' since there is no execlpe().
2399 Thu Aug 1 15:35:17 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
2401 * Makefile.in, doc/gdbrc.tex, doc/rc-* (new files):
2402 Minor rearrangement of refcard permits two new make targets--
2403 gdbrc.dvi DVI output for refcard, using CM fonts
2404 gdbrc.ps PostScript refcard, using PS fonts
2406 Wed Jul 31 16:46:21 1991 John Gilmore (gnu at cygint.cygnus.com)
2410 * TODO, Projects, WHATS.NEW, README: Update for gdb-3.98.
2411 * Makefile.in (gdb-all.texinfo): Avoid touching file if M4 dies.
2413 Wed Jul 31 16:35:58 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
2415 * doc/gdb.texinfo: last changes for release.
2416 Minor typo and formatting fixes; incorporated most fixes remaining from
2417 filed mail commenting on earlier drafts.
2419 Added warnings: pipes don't work in run command;
2420 conditions are converse of assertions;
2421 step over fn without debug info goes to next fn;
2422 vars may have "wrong" values near fn entrance, exit
2424 Added example from Kingston on printing repeated nonadjacent values
2426 Added explicit mention that in Emacs gdb mode C-c and C-z are like
2427 shell mode for signals
2429 Renamed "Stepping and Continuing" to "Continuing and Stepping" so it
2430 doesn't sound so much like its parent "Stopping and Continuing"; also
2431 moved entries on continue to top of section, so they don't get lost.
2433 Improved installation directions in appendix, added manual formatting
2436 Tue Jul 30 17:26:39 1991 John Gilmore (gnu at cygint.cygnus.com)
2438 * configure.in: Remove xm.h and tm.h even if we aren't linking
2439 new ones, so "./configure sun4; ./configure none" does the right
2440 thing. Assume that alldeps.mak and depend are already built in
2441 srcdir, and avoid running "make" (particularly "make depend",
2442 which involves "gcc") from inside configure. Build Makefile
2443 directly rather than building Makefile.conf first.
2444 * configure: Regenerate with above changes.
2445 * Makefile.in: Use $(BISON) to find bison. Roll VERSION
2446 to 3.98. Revise gdb.tar.Z procedure to produce a file
2447 called gdb-$(VERSION).tar.Z but which unpacks into a
2448 directory called "gdb". Move non-source files out of
2449 $(SFILES_SUBDIR). Pretty up alldeps.mak with comments.
2450 (depend): Don't try to do "gcc expread.y".
2451 (expread.o): Update dependencies by hand.
2453 Mon Jul 29 15:21:09 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
2456 Fixed a variety of small typos that prevented info from formatting
2457 cleanly; altered too-long heading for GPL Appendix, as discussed
2458 w/RMS; Changed date on cover to July 91.
2460 Fri Jul 26 13:20:02 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
2463 (1) Applied some fixes due to comments from Larry Breed (easier ones
2464 through chapsec 5.2)
2465 (2) Eliminated use of @footnote---had my doubts about it anyways, and
2466 it's broken in latest texinfo
2467 (3) Introduced *some* use of [] for optional arguments, where
2468 explanation is not simpler by listing cmd w arg and cmd w/out arg
2469 separately. Still not using @deffn.
2470 (4) Dropped in GPL-2. NOTE: one of GPL-2 or texinfo is broken; a
2471 couple of headings are too long. Need patches to texinfo or revision
2474 * Partial update to README (which still needs work for this
2475 release!): (1) use of configure corrected for new script,
2476 (2) "make gdb.dvi" and "make gdb.info" mentioned.
2478 Wed Jul 24 06:44:02 1991 John Gilmore (gnu at cygint.cygnus.com)
2480 * symtab.c (lookup_symbol): Don't complain right off about
2481 no debug symbols; use the misc function vector first.
2482 (list_symbols): Use misc function vector to find symbols
2483 that don't have debug info, and print them.
2484 (find_pc_symtab): Temporarily avoid fatal() when psymtab
2485 PC range doesn't match symtab PC range, as it does on the
2486 MIPS because our symtab reading isn't perfect.
2488 * dbxread.c (dbx_symfile_read): Make warning about
2489 "no debug symbols" slightly nicer.
2491 * source.c (select_source_symtab): If "main" symbol exists,
2492 but decode_line_spec can't find line info, don't just return
2493 a zero; try other source symtabs or give an error.
2495 * mipsread.c (parse_partial_symbols): Sort the psymtabs by
2496 their low addresses first, then rip through fixing high addrs.
2498 * ns32k-opcode.h (sfsr): Bugfix from Rune Nerg}rd,
2499 <runene@ifi.uio.no>.
2500 (NS32K_SVC_IMMED_OPERANDS): Reverse the #ifndef.
2502 Tue Jul 23 18:52:43 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
2504 * Minor, mostly mechanical, cleanup of doc subdir for clean
2505 makeinfo'ing and TeXing; also ensured gdb-all.texinfo (post-m4)
2506 and gdb.info (post- texinfo2 makeinfo) generated for distribution.
2508 Sun Jul 21 03:54:52 1991 John Gilmore (gnu at cygint.cygnus.com)
2510 Mostly MIPS and general symbol-reading fixups.
2512 * doc/gdbint.texinfo: Add documentation on symbol-reading
2515 * mipsread.c: Remove kludges around #include "ecoff.h".
2516 Remove redefinitions of a_magic, etc, no longer used.
2517 (parse_symbol, ): Convert "Internal:" printfs to complain()ts.
2518 Fix global overview comments to match symfile.c protocol.
2519 (mipscoff_new_init): Eliminate cur_hdr if we have one.
2520 (mipscoff_symfile_read): Eliminate unused code. Avoid
2521 sorting all the symtabs, when all we have read here is psymtabs.
2522 The symtabs are sorted as they are created anyway. Tell
2523 condense_misc_bunches whether we're mainline.
2524 (psymtab_to_symtab_1): Pass filename when recursing, to make
2525 stack trace more informative.
2526 (parse_partial_symbols): Assume cur_hdr as argument.
2527 (read_mips_symtab): Don't clobber cur_hdr, so it can be freed.
2528 Pass cur_hdr implicitly to parse_partial_symbols. Avoid checking
2529 the TYPE_NAME of char *, since that's done in symfile.c.
2530 (free_numargs, parse_symbol, add_symbol, add_block,
2531 shrink_linetable): Declare these fns void.
2532 (upgrade_type): Convert tree of if's to switch. Clean up
2533 bogus "off == 0" handling with a complaint. Avoid setting
2534 field bitpos and bitsize of array with lower and upper bounds.
2535 Check specified bitsize of elements against their actual type's
2536 bitsize, and complain if different. Complain about unknown
2538 (parse_fdr): Don't assume sizeof(char *) == sizeof (struct *).
2539 (psymtab_to_symtab_1): Print names of subsidiary files that
2540 are being read in. FIXME, we read far too many files. This code
2541 is not the problem, the problem is in parse_fdr where the psymtabs
2543 (cross_ref): Result should indicate that we used one aux entry
2544 normally, or two if we encountered a "next" entry. This used
2545 to leave the caller pointing at the wrong aux entry.
2546 (add_symbol): If overflowed cur_block, reallocate it larger,
2547 chase all pointers to it, and complain(), rather than clobber memory.
2548 (shrink_block): Use xrealloc rather than xmalloc-and-copy.
2549 (new_field): Only allocate one field initially, not two.
2550 Pull ++ out of macro argument. Simplify.
2551 (_initialize_mipsread): Avoid initialization of importd
2552 global_psymbols and static_psymbols.
2554 * symfile.c (psymtab_to_symtab): Depend on XXX_psymtab_to_symtab
2555 to properly set pst->symtab; avoid searching for it.
2556 (symfile_fns): Improve comments, add a FIXME.
2557 * dbxread.c: Update comments to reflect symfile protocol.
2558 (read_ofile_symtab, end_symtab): Return the symtab.
2559 (psymtab_to_symtab_1): Set pst->symtab.
2561 * coffread.c (coff_symfile_read): tell condense_misc_bunches
2562 whether we're mainline.
2564 * symfile.h (sym_fns): Remove unused sym_discard member.
2565 * coffread.c, mipsread.c, dbxread.c: Remove XXX_symfile_discard.
2567 * mtrace.c (mtrace): Take effect if mallwatch is set, even if
2568 the environment variable is not.
2569 * infcmd.c (finish_command): Use filtered printfs.
2570 * cplus-dem.c: Add struct tags to a few unnamed structs.
2571 * valops.c (value_coerce_array): Improve comments.
2572 * valprint.c (type_print_varspec_suffix): Print array size only
2573 if greater than zero.
2574 * m88k-tdep.c: Shift some lines left by one space, that had
2575 apparently been trashed at some point.
2576 * TODO: More things to do, a few got done.
2578 Thu Jul 18 22:46:05 1991 John Gilmore (gnu at cygint.cygnus.com)
2580 * symtab.h (LOC_EXTERNAL): Eliminate in favor of LOC_STATIC.
2581 (ldsymoff, ldsymlen, globals_offset, statics_offset): Improve
2583 * dbxread.c (read_dbx_symtab): LOC_EXTERNAL -> LOC_STATIC.
2584 * expread.y, findvar.c, symmisc.c: Ditto.
2585 * printcmd.c (address_info): Update printed forms of LOC_
2586 symbols. Elim LOC_EXTERNAL.
2587 (print_frame_args): Keep track of param stack offsets before
2588 re-looking up to find the local register param is kept in.
2590 * mipsread.c: Use <symconst.h> and <sym.h> rather than <syms.h>.
2591 Further integration of mipsread into gdb. Eliminate unused
2592 routines, duplicate declarations. Handle static symbols in
2593 psymtabs as well as external symbols. When reading symtabs,
2594 insert symbols into the correct block (global, static, or a local
2596 (read_mips_symtab, parse_partial_symbols): Don't pass useless
2598 (mipscoff_symfile_read): Don't call select_source_symtab.
2599 (parse_symbol): Use SYMBOL_VALUE_ADDRESS where appropriate,
2600 rather than SYMBOL_VALUE.
2601 (parse_external): Comment clobbering of top_stack.
2602 (parse_partial_symbols): Update comments. Allocate and parse
2603 static symbols as well as external symbols. FIXME, enum values
2604 are not handled in this pass, but should be. Inline new_psymbol.
2605 Use SYMBOL_VALUE_ADDRESS.
2606 (psymtab_to_symtab_1): Read symbols into global static block
2607 by default (until enter some function's local block context).
2608 (sort_blocks): Clean up STATIC_BLOCK as well as GLOBAL_BLOCK.
2609 (destroy_all_symtabs, new_psymbol): Eliminate, unused.
2611 * source.c (select_source_symtab): Select a source symtab
2612 from either the symtabs or, failing that, the psymtabs.
2613 (list_command): Update error message.
2614 (forward_search_command, reverse_search_command): Use getc, not
2615 fgetc, for speed. FIXME, add comment about buffers that die if
2616 overrun by long line.
2618 * values.c (unpack_field_as_long, modify_field): Avoid shifting
2619 by an entire word, which is not portable, if we have a 32-bit
2620 field. (Code in dbxread.c already turns such bitfields, if
2621 aligned, into ordinary ints, but fixing this will help for other
2622 symbol formats and for future changes.)
2623 * core.c (core_open): Handle ANSI const brain death.
2624 * utils.c (vprintf): Fix varargs typo.
2626 Sun Jul 14 00:42:53 1991 John Gilmore (gnu at cygint.cygnus.com)
2628 * findvar.c (find_var_value): Handle &function better.
2629 * TODO: Document work needed on &fn and &array.
2630 * printcmd.c (print_address_symbolic): New arg is the prefix
2631 to print if a name is printed.
2632 (print_address_demangle): Honor "set print address" now.
2633 Use new arg above to improve spacing of output.
2634 * valprint.c (val_print): When printing function pointers,
2635 print symbolic form too.
2636 * breakpoint.c (breakpoint_1): Use new print_address_symbolic.
2638 Mon Jul 8 19:02:46 1991 John Gilmore (gnu at cygint.cygnus.com)
2640 * core.c (memory_error): Reword error msg to mislead less.
2642 * mips-pinsn.c (print_insn_arg 'd'): Print $ with reg name.
2644 * mipsread.c (read_mips_symtab, read_the_mips_symtab,
2645 parse_partial_symbols): Use newer BFD internals (external_filehdr
2646 and external_aouthdr), byte-swap the fields that we care about
2647 before using them, and make the file header data local to
2648 read_the_mips_symtab rather than global.
2650 Sat Jul 6 01:34:15 1991 John Gilmore (gnu at cygint.cygnus.com)
2652 * ns32k-opcode.h (movmw, movmd): Fix opcodes. Bug fix
2653 from Rune Nerg}rd <runene@ifi.uio.no> on 5 Jul 1991.
2655 * main.c (command_line_input): Flush stdout and stderr
2656 before every call to readline. This reportedly fixes a bug
2657 that comes up in Sys V running emacs-gdb and/or xxgdb,
2658 when stdin/out are pipes or sockets.
2660 Thu Jul 4 14:47:06 1991 John Gilmore (gnu at cygint.cygnus.com)
2662 * configure.in, Makefile.in: Avoid rebuilding "depend" as much.
2663 Avoid declaring Makefile dependencies, because GNU Make stupidly
2664 tries to update it if we do.
2666 * coffread.c: Revise for minor changes to bfd internal coff
2669 * configure: If -template= is given a relative path, make it
2670 absolute before recurring in subdirectories.
2672 * configure, configure.in, Makefile.in: Install "configure" script
2673 as replacement for config.gdb.
2674 * config.gdb, Makefile.dist, Makefile.sdir: Remove
2675 * README: Update for configure, mostly. FIXME.
2677 * Add dec3100 as equivalent to littlemips. Indicate in all host &
2678 target config files that they are for the host. When the lines
2679 get copied into the Makefile, this makes it more obvious what's
2682 Mon Jun 24 23:49:07 1991 John Gilmore (gnu at cygint.cygnus.com)
2684 * sparc-opcode.h (trap opcodes): Avoid leading spaces or
2685 tabs, which end up in the disassembler output inadvertently.
2687 Wed May 29 23:01:03 1991 John Gilmore (gnu at cygint.cygnus.com)
2689 Make it compile cleanly in an ANSI GCC2 environment.
2691 * blockframe.c: <stdio.h>
2692 * cplus-dem.c: free takes a void *, ifdef __STDC__
2693 * dbxread.c (read_huge_number): avoid gcc2 bug hoisting calc of
2695 * defs.h (alloca): Avoid doing anything if alloca already def'd.
2696 * stddef.h, stdlib.h: Remove these files.
2697 * symtab.c: Avoid declaring qsort, close.
2698 * symfile.c: Avoid declaring close.
2699 * utils.c (vprintf): Declare "ap" arg as proper va_alist.
2700 * sparc-tdep.c: Avoid including lots of Sun-host-specific files.
2702 Assorted other changes.
2703 * dbxread.c: include "libaout.h", not "liba.out.h".
2704 * printcmd.c (print_frame_args): Set recurse properly for
2705 indentation of struct and array parameters.
2706 * valops.c (value_cast): Allow cast to void.
2707 * infrun.c (resume): If NO_SINGLE_STEP, call machine dependent
2708 single_step() in a target-independent fashion.
2709 * sparc-tdep.c (single_step): Don't call ptrace ourselves, just
2710 set up to be ready to continue. This makes us target independent.
2711 * infptrace.c (child_resume): Remove call to single_step; now
2712 can single step a SPARC target of any kind.
2714 Wed May 22 18:18:24 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
2716 * Makefile.dist, doc/gdb.texinfo, doc/*-m4.texinfo: split up GDB
2717 docn into separate sections---basically chapters, plus two loose
2718 pieces that can be configured to go in different places. This
2719 allows GNU m4 to preprocess the manual without coredumping.
2721 * Makefile.dist: tell TeX where to find texinfo.
2723 Mon May 20 12:15:04 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
2725 * Makefile.dist, doc/gdb.texinfo: respectively create, and use,
2726 the new target "rdl-apps.texinfo" which captures the Makefile
2727 variable that records where to find the Readline libraries.
2729 Sun May 19 05:36:59 1991 John Gilmore (gnu at cygint.cygnus.com)
2731 * tahoe-pinsn.c: #include "tahoe-opcode.h", not "opcode.h".
2732 * tm-tahoe.h (FIX_CALL_DUMMY): Ignore more parameters.
2733 * defs.h (const, volatile): Only define if not already defined.
2734 * Makefile.dist (gdb.tar.Z): Create doc subdir w/out CVS/RCS crud.
2736 * README: Update for release 3.95.
2737 * config.gdb: Don't create readline dir in subdir builds.
2738 * main.c: Include with "..." form for non-system include files,
2739 so "gcc -MM" for "make depend" works.
2740 Include readline files with "...h" rather than <readline/...h>.
2741 * mipsread.c: Include "ecoff.h" rather than "intel-coff.h".
2743 * coffread.c: Undo minor damage done by Rich Pixley. Use
2744 different internal and external representations of COFF
2745 data structures. Use new BFD routines for swapping them in and
2747 * symfile.c (free_named_symtabs): Avoid freeing file names that
2748 are null or empty. Old i960 tools seem to produce files that
2749 claim to have empty names, causing each successive file read
2750 to blow away the previous one.
2751 * sparc-xdep.c (deferred_stores): Repair minor damage by Rich.
2752 Move deferred_stores to top of file, but don't separate its
2753 #define's from its variable. Add commentary.
2754 * Makefile.dist: Fix Rich damage; undo "configure" changes in
2755 favor of keeping the (working) config.gdb. Move readline
2758 Fri May 17 12:49:56 1991 Per Bothner (via gnu at cygint.cygnus.com)
2760 * dbxread.c (read_struct_type): Try to handle g++ version 1 MI
2762 * infptrace.c (fetch_registers): no result, since now void.
2763 * tconfig/news: target depends on m68k-tdep too.
2765 Fri May 17 14:40:14 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
2767 * Makefile.dist: added readline/inc-*.texinfo to dependencies for
2770 * readline/inc-history.texinfo, readline/inc-readline.texinfo:
2771 applied various small fixes due to or inspired by RMS comments
2773 * doc/gdb.texinfo: finished using all RMS comments, save those for
2774 appendices on readline and cmd history (which are in other source
2777 Thu May 16 18:06:05 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
2779 * doc/gdb.texinfo: (1) Updated w/ref to RMS comments through
2780 chapter 9; (2) documented 'break' command's menu mode for
2781 overloaded names, in response to hgs problem report C++ p-31
2783 Wed May 15 11:02:48 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
2785 * doc/gdb.texinfo: (1) better introductory example; (2) more
2786 consistent use of @code, @samp, @file, @kbd throughout; small
2787 cleanups to first three nodes; (3) new "Contributors" node;
2788 (4) Appendix, Renamed Commands; (5) divert specialized startup
2789 instructions to "Targets" chapter for generic manuals, while
2790 leaving them up front for manuals specific to specialized
2791 environments; (6) apply fixes from RMS comments through chapter 4.
2793 * pretex.m4: modify explanatory text slightly (and redefine
2794 "regexp") to keep GNU m4 from complaining. (It still crashes
2795 later, but one step at a time...)
2797 Wed May 15 10:32:12 1991 John Gilmore (gnu at cygint.cygnus.com)
2799 * readline/readline.c (update_line): Avoid dereferencing a pointer
2800 before comparing it to its bounds. Saber caught this.
2801 (init_terminal_io): Don't set BC from the "pc=" termcap variable,
2802 and only set PC if tgetstr returned non-null. Saber caught this.
2804 Tue May 14 16:29:53 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)
2806 * Makefile.dist: put gdb.dvi stuff (updated to use M4 preprocessor
2807 stuff for config manual) here where it counts; updated
2808 to use new subdir structure (gdb/doc/).
2810 * Makefile: generated from above via
2814 * gdbint.texinfo: added instructions on generating gdb.info* files
2815 locally for release. These are ordinary info
2816 files, formatted from gdb.texinfo (via gdb-all.texinfo, see
2817 Makefile)---but due to use of texinfo 2, can't count on makeinfo
2818 to generate these, so we distribute them already formatted.
2820 * gdb.texinfo: included full Info node and menu crud (as generated
2821 by C-u M-x texinfo-master-menu using the texinfo-2 elisp code).
2823 * Makefile: updated "gdb.dvi" target to use M4 preprocessor;
2824 put in comments-for-future gdb.info target (one day makeinfo will
2827 Tue May 14 13:51:36 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)
2829 * gdb.texinfo: Updated to include new or old undocumented
2830 commands, at least the following (perhaps some others I forgot to
2831 record): info f, info float, info path, info program, info s, info
2832 set, info source, info terminal, info types, info user, set/show
2834 Also covered all recent GDB command renames for v4.
2836 Mon May 13 14:57:46 1991 John Gilmore (gnu at cygint.cygnus.com)
2838 * mipsread.c: Rather than keeping count of how many symtabs
2839 and psymtabs we have, for sorting purposes, count them when
2840 we need to sort. This fixes bug in rereading of symbol tables.
2842 Fri May 10 15:43:33 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)
2844 * infcmd.c: renamed "info path" to "show paths"
2845 * gdbrc.tex: documented above.
2847 Wed May 8 04:51:11 1991 John Gilmore (gnu at cygint.cygnus.com)
2849 * remote.c: Fix comments.
2850 * utils.c (error): Force out any pending wrap output.
2852 Sat May 4 11:11:07 1991 John Gilmore (gnu at cygint.cygnus.com)
2854 * Makefile.dist: Roll VERSION to 3.95.
2855 Fix up "saber_gdb" to work again.
2856 * saber.suppress: Update.
2858 * coffread.c, exec.c, infptrace.c, inftarg.c, remote.c, solib.c,
2859 symtab.h, target.c, target.h: Lint.
2860 * core.c: setup and select frame after reading shared libs,
2861 else reading shared libs will clobber them. Lint.
2862 * utils.c (error): Force out any buffered wrap text.
2864 Fri May 3 22:01:56 1991 John Gilmore (gnu at cygint.cygnus.com)
2866 * remote.c: Remove decls of memory_insert_breakpoint
2867 and memory_remove_breakpoint, no longer used. (Suggestion of
2870 * Makefile.dist: use ${subdir} in paths of BFD and LIBIBERTY,
2871 to make it easier to interface to "configure"'d libraries.
2873 Fri May 3 13:10:01 PDT 1991 Roland Pesch (pesch at fowanton.cygnus.com)
2875 * valprint.c: introduce "set p", "set pr", "show p" and "show pr" as
2876 aliases for set/show print.
2878 Thu May 2 11:22:02 1991 Jim Kingdon (kingdon at cygint.cygnus.com)
2880 * coffread.c (coff_sym_fns) [TDESC]: Make the type be m88kbcs.
2882 * m88k-tdep.c (IEEE_isNAN): New function.
2884 * infrun.c, m88k-tdep.c, m88k-xdep.c: Change
2885 initialize_{tdesc,dcontext} to init_{tdesc,dcontext}.
2887 * infrun.c [TDESC]: Add a bunch of crud.
2889 * xm-88k.h [__GNUC__]: Don't define memset.
2891 * m88k-xdep.c: #if 0 out push_breakpoint.
2893 * tm-88k.h: Define GET_SAVED_REGISTER.
2895 * tm-88k.h: Define DGUX.
2897 * m88k-opcode.h (UEXT, SEXT, MAKE): Put parentheses around arguments.
2899 * m88k-pinsn.c (sprint_address): Declare at top of file.
2901 * m88k-xdep.c: #if 0 out core_file_command.
2903 * values.c ({unpack_,value_as_}pointer): Just call
2904 {unpack_,value_as_}long (for now anyway).
2906 * m88k-tdep.c (get_saved_register): Make get_reg a dc_word_t (*)().
2907 (psr_register): Change return type to dc_word_t.
2909 * m88k-tdep.c (tdesc_read_function): Comment out call to ptrace.
2911 * m88k-tdep.c (get_saved_register): Add lvalp parameter.
2913 * gdbcore.h (write_memory): Don't prototype it.

3384 * target.h: Add to_doc and target_preopen.
3385 target.c: Add target_preopen and target_command.
3387 (add_target): Call add_cmd and mess with targetlist->doc.
3388 core.c, exec.c, remote-eb.c, remote-nindy.c, remote-vx.c,
3389 remote-vx.68.c, inftarg.c, remote.c: Add doc field to target struct.
3390 Call target_preopen from open routine.
3392 * main.c: Rename editing_info to show_commands.
3393 (_initialize_main): Rename "info editing" to "show commands".
3395 * source.c: Rename directories_info to show_directories.
3396 (_initialize_values): Rename "info directories" to "show directories".
3398 * values.c: Rename convenience_info to show_convenience.
3399 (_initialize_values): Rename "info convenience" to "show convenience".
3401 * copying.awk (_initialize_copying): Rename "info copying" to
3402 "show copying" and "info warranty" to "show warranty".
3403 Rename {copying,warranty}_info to show_{copying,warranty}.
3405 * symfile.c: Rename add_syms_command to add_symbol_file_command.
3406 (_initialize_symfile, add_syms_addr_command):
3407 Rename add-syms to add-symbol-file.
3409 Thu Apr 18 18:08:30 1991 John Gilmore (gnu at cygint.cygnus.com)
3411 * symfile.h (free_named_symtabs): Rename from free_named_symtab.
3412 * symfile.c (clear_symtab_users_once, cashier_psymtab,
3413 free_named_symtabs): Move these routines from symmisc.c.
3414 * symmisc.c (same): same.
3415 (free_symtab): Make non-static.
3416 * symtab.h (free_symtab): Declare as exported void fn now.
3417 * dbxread.c (end_symtab, end_psymtab): Change comments.
3418 (initialize_dbxread): Call dbx_new_init() in case the first
3419 command is add-symbols.
3420 * target.c (dummy_target): Permit add_syms_addr_command.
3422 Sat Apr 13 14:46:07 1991 John Gilmore (gnu at cygint.cygnus.com)
3424 Permit symbols to be superseded when new symbol files have
3425 been read in, particularly for VxWorks.
3427 * dbxread.c (read_dbx_symtab): Allow N_SOL to cleanly take us back
3428 to the main file, as well as to include files. Also, put global
3429 functions into the global psymtab, to make "i fun" work.
3430 (end_psymtab): Free named symtabs and psymtabs for a file, once a
3431 new psymtab for it has been read.
3432 * coffread.c (end_psymtab): Free named symtabs and psymtabs for
3433 a file, once a new symtab has been read for it.
3434 * mipsread.c: FIXME. We need to do the same for MIPS, but it
3435 looks harder to determine the top-level block before it's been
3436 queued to the psymtab list.
3438 * symfile.c (symbol_file_add): Use filtered printing and wrap it.
3439 If we have wiped out any old symbol tables, clean up at end of
3441 (symbol_file_command): Don't reference symfile_fns if it's zero.
3443 * symtab.h (GLOBAL_BLOCK, STATIC_BLOCK, FIRST_LOCAL_BLOCK): New
3444 defines for the blocks of a blockvector that contain global and
3445 file-static symbols and the first of the smaller scope contours.
3446 * symtab.c (lookup_symbol, find_pc_symtab, find_pc_line,
3447 decode_line_1, make_symbol_completion_list): Use the above.
3448 * coffread.c (end_symtab, patch_opaque_types): Ditto.
3449 * dbxread.c (end_symtab): Ditto.
3450 * expread.y (block): Ditto.
3451 * mipsread.c (throughout): Ditto.
3452 * symmisc.c (free_named_symtabs): Ditto.
3454 * symtab.c (list_symbols): Process the first symbol of the
3455 static psymbols list.
3456 (types_info): Restore this function from its untimely #if 0.
3457 It's not perfect, but it is better than nothing.
3458 (_initialize_symtab): Restore "info types".
3460 Thu Apr 11 05:23:19 1991 John Gilmore (gnu at cygint.cygnus.com)
3462 * m68k-stub.c: Remote stub for 680x0's, created from
3463 rem-m68k.shar (which is removed).
3464 * nindy-share/{Makefile,Onindy.c,blout.h,env.h,nindy.c,ttyflush.c}:
3465 Remove RCS log stuff now that we use CVS and it blows our diffs.
3467 Wed Apr 10 14:18:06 1991 John Gilmore (gnu at cygint.cygnus.com)
3469 * symmisc.c (free_named_symtab): Make it work, in its current
3470 kludgy fashion. Change result to indicate if we blew away bkpts.
3471 * dbxread.c (end_symtab): Accumulate result from
3472 free_named_symtab and print warning if we blew user's state.
3473 * symfile.h: free_named_symtab now returns an int.
3475 Mon Apr 8 23:57:43 1991 John Gilmore (gnu at cygint.cygnus.com)
3477 * dbxread.c (dbx_symfile_read): Initialize psymbol list if this
3478 is the first symbol read, even if not mainline.
3479 (dbx_psymtab_to_symtab): symfile might be zero, cope.
3480 * exec.c (exec_ops): Add_syms_addr is valid in our tvec.
3481 (set_section_command): New command ("section xxx yyy" -- should
3482 be renamed to "set section xxx yyy" FIXME) which sets the
3483 base address of a section of the exec file, overriding the
3484 virtual address that BFD reports.
3486 Fri Apr 5 17:14:39 1991 John Gilmore (gnu at cygint.cygnus.com)
3488 * exec.c: Add add_syms_addr_command to exec_ops, so you can
3489 load symbols at any address while examining an exec file.
3491 Thu Apr 4 10:09:35 1991 John Gilmore (gnu at cygint.cygnus.com)
3493 * tm-i386v.h (FLOAT_INFO): Don't define it, since the code
3494 for printing the float info is host-dependent, not
3495 target-dependent. FIXME.
3496 * i386-pinsn.c: Move #includes to top, remove useless ones.
3497 * i386-tdep.c: Don't bother including <.../reg.h> since we
3498 don't use it (and it doesn't exist on host systems).
3500 * ieee-float.c (ieee_extended_to_double): Convert NaN to Inf.
3501 Convert negative numbers properly.
3502 (ieee_test): Make numbers really random; fix format arg.
3504 * infcmd.c (attach_command, detach_command): Don't repeat on CR.
3505 * core.c (core_detach): Unpush core_ops, which might not be on
3506 top. We used to just pop the top, which broke things. Don't
3507 need dont_repeat() any more.
3508 (core_file_command): Psst! Don't repeat it.
3509 * remote-nindy.c (nindy_detach): Don't need dont_repeat() now.
3510 * expprint.c (print_subexp): Avoid switch fallthru on
3511 BINOP_ASSIGN_MODIFY, so we can print += and such.
3512 * frame.h: Fix typo.
3513 * inflow.c (kill_command): After killing inferior, print our
3514 current frame in the core file, if we have one.
3515 (generic_mourn_inferior): When inferior dies, either select
3516 the current frame (in the new target, e.g. core file), or
3517 set both the current and selected frames to NULL.
3519 Changes from Peter Schauer.
3521 * infptrace.c: Avoid <sys/ptrace.h> on USG.
3523 * Make all file names fit in 14 characters (sigh and damn!):
3524 mv hp300hpux-xdep.c hp300ux-xdep.c
3525 mv symmetry-xdep.c symm-xdep.c
3526 mv symmetry-tdep.c symm-tdep.c
3527 mv convex-opcode.h convx-opcode.h
3528 mv tm-vxworks960.h tm-vx960.h
3529 mv tm-vxworks68.h tm-vx68.h
3530 mv Makefile.srcdir Makefile.sdir
3531 mv gdb-int.texinfo gdbint.texinfo
3532 mv remote-sa.m68k.shar rem-m68k.shar
3533 mv remote-multi.shar rem-multi.shar
3534 * Makefile.dist, README, config.gdb, convex-pinsn.c,
3535 tconfig/symmetry, tconfig/vxworks960, tconfig/vxworks68,
3536 xconfig/hp300hpux, xconfig/symmetry: Change names to shorter
3539 * command.c (user_info_1, user_info): New command for listing
3540 the user-defined commands.
3542 Wed Apr 3 15:00:26 1991 John Gilmore (gnu at cygint.cygnus.com)
3544 * dbxread.c (really_free_pendings): Clear file_symbols
3545 and global_symbols after freeing them; otherwise, running
3546 this function twice (if it appears twice on the cleanup
3547 chain), we try to free things twice.
3549 * dbxread.c (read_dbx_symtab): Calculate end_of_text_addr
3550 based on text_addr (the address of text in core), not on addr (the
3551 offset between text in the .o file and in core). This change
3552 is from Peter Schauer.
3554 * main.c: Define ALL_CLEANUPS as a cast of zero.
3555 (return_to_top_level): Use it.
3556 (main): Do all cleanups after each command run as part
3557 of the gdb startup sequence. Also do all cleanups before
3558 entering the command loop, and every time we exit the command
3559 loop and reenter. Before, the cleanups from the startup sequence
3560 were being left undone until the first error!
3561 (command_loop): Rename do_nothing cleanup to command_loop_marker
3562 so we can see it easily when examining the cleanup chain.
3563 (init_signals): Add another do_nothing for signal handling.
3564 (quit_command): Only try to kill target if it has execution.
3565 Problems in the target stack got us into a state where
3566 inferior_pid was nonzero but none of the targets had execution.
3567 In this state you couldn't exit gdb.
3569 * dbxread.c: Two changes from Peter Schauer.
3570 (echo_command): Fflush output after an echo command.
3571 (show_history): Pass all args to cmd_show_list.
3573 * utils.c (init_malloc): Call mtrace to turn on tracing
3574 if the environment variable MALLOC_TRACE is set to a file name.
3575 * mtrace.c: Add source file which provides a log of every malloc,
3576 free, and realloc to a trace file.
3577 * mtrace.awk: Add source file which analyzes the trace file.
3578 * Makefile.dist (GNU_MALLOC, MALLOCSRC): Add mtrace.{c,o,awk}.
3579 (VERSION): Roll to 3.94.3.
3581 * breakpoint.c (breakpoint_1): Add a space to "i watch" output.
3582 (check_duplicates): Don't bother with watchpoints.
3583 (set_raw_breakpoint): Comment about danger of this routine.
3584 (watch_command): Parse and eval all args before calling
3587 * solib.c (find_solib): Avoid error in referencing memory to
3588 see if any more shared libraries have been added. This is
3589 particularly useful if the target has terminated. Bug reported
3592 Changes from Peter Schauer <pesrem@regent.e-technik.tu-muenchen.de>
3593 in bringing up 3.94.2 on the Sun-3.
3595 * Makefile.dist: Include CFLAGS in rule for cplus-dem.o.
3596 * breakpoint.c (enable_breakpoint): Check for valid watchpoint
3597 expression (in scope) before reenabling watchpoint.
3598 * signame.c (init_sigs): Add missing declaration of i, fix
3599 sys_siglist declaration.
3600 * source.c (list_command): Fixed range computation to use
3602 * stack.c (backtrace_command): Do not allow command if target has
3603 no stack, print informative error message.
3604 * target.c (target_command): Do not write into command line
3605 because this fails if the target command is used in a user defined
3606 command. [This change was enhanced by gnu to support any-
3607 unique-prefix matching on target names.]
3608 * valops.c (value_struct_elt): Avoid infinite loop on an
3609 erroneous attempt to print the member of function (try p main.p).
3611 Mon Apr 1 17:05:45 1991 John Gilmore (gnu at cygint.cygnus.com)
3613 * expread.y (name_no_typename): Avoid reduce/reduce errors
3614 caused by ambiguity in handling NAME_OR_INT and NAME_OR_UINT.
3615 Since the GDB parser really doesn't use name_no_typename in a
3616 name-only context, the parser can't tell the diff between
3617 names and numbers here. Avoid allowing a name_no_typename
3618 to be a NAME_OR_*INT to resolve the conflict.
3620 Sun Mar 31 20:12:07 1991 John Gilmore (gnu at cygint.cygnus.com)
3622 Bugfixes from Mark Fox (markf@wrs.com) (test=testField.c):
3624 * valprint.c (val_print_fields): bitfield printing didn't handle
3625 byte order. Indirect through a few more fns to cope.
3627 * values.c (modify_field): also cope with byte order.
3629 Sat Mar 23 10:02:21 1991 John Gilmore (gnu at cygint.cygnus.com)
3631 Cleanup for release 3.94.2:
3633 * Makefile.dist: Pull REMOTE_OBS. Fix saber includes for BFD
3634 include files. Roll version to 3.94.2.
3636 * coffread.c (init_stringtab): Read length into unsigned char
3637 array before swapping; don't assume 32-bit longs.
3639 * target.c (target_info): Don't bother with get_sym_file, just use
3640 the symfile global variable.
3641 * symtab.h, symfile.c (get_sym_file): Delete it.
3643 * dbxread.c (dbx_symfile_init): Don't depend on long == 4 bytes.
3644 (define_symbol): Set symbol line number to 0 if not gcc-compiled.
3645 (read_type): Replace one more error() with complain().
3647 * mipsread.c (parse_partial_symbols): Replace printf with complain.
3649 * i960-tdep.c: Fix copyright attribution.
3651 * config.gdb: Quote all backquotes in doublequotes. You can
3652 quote me on that. BSD 4.4 shell found this one.
3654 * infptrace.c (throughout): The third argument to ptrace is an
3657 * infrun.c (wait_for_inferior): When program has terminated, we
3658 have to call target_terminal_ours before we pop that target off
3659 the stack (e.g. before a call to target_kill or
3660 target_mourn_inferior). This fixes problem where a program
3661 terminates, then GDB stops for (tty output) and you have to type
3662 "fg" to the shell to resume it. FIXME: This code for what to
3663 do after termination really should be in normal_stop instead.
3665 * gdbcore.h (read_memory_check): Change declaration; it changed
3668 * terminal.h: Include <sgtty.h> before <sys/ioctl.h>, since in BSD
3669 4.4 prereleases, this avoids a bug in their sgtty compatability
3671 * remote.c: Use terminal.h rather than hand-rolling the same.
3673 * signame.c, signame.h (psignal): Arg is unsigned, not int.
3674 * utils.c (strsave, strstr): Fix arg types.
3675 * valprint.c (val_print): lint
3677 MIPS symbol table support from Per Bothner:
3679 * symfile.c (symtab_fns): Remove initializer table that needs to
3680 be hacked for each new symbol file format supported.
3681 (add_symtab_fns): New function, chains symbol table
3682 handlers into the global list.
3683 (symfile_init): Search this list.
3684 * symfile.h: Add next pointer, declare add_symtab_fns.
3685 * coffread.c (_initialize_coffread): Call add_symtab_fns.
3686 * dbxread.c (_initialize_dbxread): Call add_symtab_fns.
3688 * mipsread.c (psymtab_to_symtab_1): return void instead of (struct
3689 symbol *). Thus, we no longer need the hack to trash
3690 pst->filename. Good, since that hack confused code in symfile.c!
3692 (reorder_symtabs, destroy_all_symtabs): Removed static
3693 all_symtabs, which was used to qsort symtabs in reorder_symtabs.
3694 Instead, the latter now uses a temporary array (stack-allocated
3695 from an obstack, and then freed).
3697 (parse_symbol): Added a hack to fix up BLOCK_{START,END} if they
3698 haven't been set in the outermost stBlock of a procedure. This was
3699 a problem with f77 binaries on Ultrix 4.?.
3701 (new_symtab, new_symbol, new_type): Continue changing code to use
3702 obstacks more and otherwise conform to dbxread internal style.
3703 Made the free_code of symtabs be free_linetable (as in dbxread)
3704 instead of free_contents. This implies memory leaks when reading
3705 a new symbol table, until the conversion is finished. Did change
3706 (struct symbol) and (struct type) to be allocated on the
3707 symbol_obstack. Blocks and blockvectors are among the things
3710 * mipsread.c (parse_partial_symbols, parse_fdr): It hasn't been
3711 tested much, but it solved one problem (reported by Meissner), and
3712 cleans up some other things. The problem happened when an
3713 included file contains actual code (functions) and not just
3714 definitions. The mips coff is a little inconvenient there, since
3715 it may cause a procedure to be mapped to the wrong psymtab.
3717 * mips-tdep.c (heuristic_proc_desc): Minor cleanup.
3718 * mips-xdep.c (fetch_core_registers): Minor cleanup. FIXME,
3719 this will need work for the new core paradigm.
3721 Opcode patches from the net:
3723 * mips-opcode.h: fix incorrect disassembly of the mfc1, cfc1, and
3724 ctc1 instructions. Also, the cvt.d.w and cvt.s.w instructions were
3725 missing altogether - they are added here. From Bruce Bauman.
3726 * mips-opcode.h: The low mask for C0 instructions was too small.
3727 From Garrett Lau. I modified the fix to check the entire 32-bit
3730 * ns32k-opcode.h: Fix opcodes for deiw and deid. From Bruce
3733 Thu Mar 21 12:56:46 1991 John Gilmore (gnu at cygint.cygnus.com)
3735 Roll in changes from Per Bothner (Tue, 25 Sep 90 11:11:04):
3737 * dbxread.c (read_type): Pointer subtraction (value_sub in
3738 valarith.c) sometimes failed because the types of the
3739 pointers being subtracted were not identical.
3740 These differed because dbxread.c was allocating pointer types
3741 using dbx_alloc_type+smash_to_pointer_type instead of
3742 lookup_pointer_type. I failed to find a justification for the
3743 former, so I changed it to use the latter. Similarly, I
3744 replaced smash_to_function_type by lookup_function_type,
3745 and smash_to_reference_type by lookup_reference_type.
3747 * mipsread.c (parse_symbol, upgrade_type, parse_procedure,
3748 _initialize_mipsread): corresponding changes.
3750 * symtab.c (smash_to_{pointer,reference,function}_type): eliminate.
3752 * source.c (mod_path): Do tilde_expand on each component of the path,
3753 rather than on the (list of) paths as a whole.
3754 (print_source_lines): Set first_line_listed in addition to
3755 current_source_symtab and current_source_line. If the source was
3756 not findable, after a "dir" command to fix the problem,
3757 a "list" would get the wrong lines.
3759 While I was there... (gnu):
3761 * dbxread.c (read_type): Change error to complaint.
3763 Thu Mar 21 12:56:46 1991 John Gilmore (gnu at cygint.cygnus.com)
3765 First attempt at detailed understanding of symbol table memory alloc.
3767 * dbxread.c (dbx_symfile_read): Free our string table if we
3768 aren't the mainline. Free the "info" struct since we're done with
3770 (init_psymbol_list): Free any previously allocated psymbol lists.
3771 (): FIXME: Should realloc-down the psymbol lists when done reading
3772 the main symbol file?
3774 * symmisc.c (free_symtab): Free fullname field too.
3776 * xm-hp300hpux.h (USG): #undef then #define so Makefile can -D.
3777 (REGISTER_ADDR): Make result type unsigned int.
3779 * xconfig/{i386*,hp300hpux,altosgas,altos}: All config files that
3780 define REGEX must also define REGEX1 (its dependency).
3782 Tue Mar 19 21:28:57 1991 John Gilmore (gnu at cygint.cygnus.com)
3784 * tconfig/i960: No longer works, points you at vxworks960 or
3787 * xgdb.c, XGDB-README: Remove file. Users can get the much
3789 * Makefile.dist: Remove all trace of xgdb.
3791 * breakpoint.c (breakpoint_1): Pass demangle arg to
3792 print_address_symbolic.
3793 (clear_breakpoints): Remove unused function.
3794 (breakpoint_re_set_one): Guts of breakpoint_re_set.
3795 (breakpoint_re_set): Use catch_errors to do them all anyway.
3797 * gdb-int.texinfo (Host versus Target): Add section on what is
3798 a "host" feature versus what is a "target" feature.
3800 * infcmd.c (path_command, path_info): Handle the PATH variable
3801 (object search path) as conveniently as the source search path.
3802 * environ.c (set_in_environ): Set some vars in GDB's environment,
3803 in addition to the child's. PATH, G960BASE, G960BIN for starters.
3804 * source.c (mod_path): New function, from guts of
3805 directory_command, modifies a path. Used by path_command.
3806 (directory_command): Call it.
3807 * defs.h (strsave): Declare.
3809 * utils.c (sevenbit_strings): Add new printing option.
3810 (printchar): Use it.
3811 (strsave): Provide this handy helper routine.
3812 (set_width_command): Rename set_screen_width_command.
3813 (_initialize_utils): "set screen-width" => "set width";
3814 "set screen-height" => "set height"; add sevenbit-strings.
3816 * infcmd.c (do_registers_info): Print floating point registers
3817 in raw hex as well as float format, regardless of whether it is
3818 a "virtual" convertible register.
3819 * tm-sparc.h (PRINT_REGISTER_HOOK): Print every pair of float
3820 regs as a double, just in case it's being used that way.
3821 * values.c (unpack_long): Comment on array/function coercion.
3822 (unpack_double): Argument is in target byte order now. For
3823 integer arguments, just call unpack_long and float the result.
3824 * m68k-tdep.c: include defs.h for "const" handling.
3825 * remote-nindy.c: Use ieee-float stuff.
3826 (nindy_fetch_registers): Unpack double regs to host double, then
3828 (nindy_store_registers): Pack extendeds to host double, flip
3829 around by misusing unpack_double, send as target double.
3831 * tm-vxworks68.h (FRAME_CHAIN): Handle current frame pointer of
3832 zero, as when stopped at the first instruction of a process.
3834 * blockframe.c: Fix filename in comment (param.h => tm.h).
3835 * sparc-tdep.c (skip_prologue): More explicit nudging comments.
3836 * tm-68k.h: Fix typos.
3838 Fri Mar 15 01:09:34 1991 John Gilmore (gnu at cygint.cygnus.com)
3840 Changes from a bringup on the DEC Vax under Ultrix 4.0.
3842 * coredep.c (fetch_core_registers): Pass end-address of register
3843 section to register_addr as expected. Don't call supply_register
3844 if we'd just pass it garbage.
3846 * dbxread.c (read_dbx_symtab): Skip N_NSYMS on Ultrix.
3848 * exec.c (xfer_memory): Use boolean xfer_fn result, not int.
3850 * target.c (push_target, target_info): Cast enums to int for < or
3853 * stack.c (print_frame_info): Identify source file & line
3854 even if we can't print it.
3856 * xm-vax.h (MISSING_VPRINTF): No longer missing in Ultrix V4.0.
3858 Sat Mar 9 10:08:20 1991 John Gilmore (gnu at cygint.cygnus.com)
3860 Clean up IEEE floating point support.

3872 * m68k-tdep.c: Define ext_format_68881.
3873 * sparc-tdep.c: Define ext_format_sparc, though unused.
3874 * Makefile.dist (HFILES): Add ieee-float.h.
3875 * inftarg.c: #include "ieee-float.h" for the REGISTER_CONVERT
3878 Obsolete the "coffstrip" program in favor of using BFD's strip.
3880 * nindy-share/coffstrip.c: Remove file.
3881 * nindy-share/nindy.c (coffstrip): Routine to run bfd_strip.
3882 * Makefile.dist: Remove references to nindy-share/coffstrip.c.
3883 * tconfig/nindy960: Remove reference to coffstrip.o.
3885 * Makefile.dist: Roll version number to 3.94.1 (not yet final).
3887 Wed Mar 6 09:56:45 1991 John Gilmore (gnu at cygint.cygnus.com)
3889 * symfile.h: Add symfile_bfd, common between dbxread and coffread.
3890 * dbxread.c: Remove static symfile_bfd.
3891 * infcmd.c (do_registers_info): Add PRINT_REGISTER_HOOK, though
3893 * inftarg.c (child_detach): Pop the child_ops vector if the
3894 detach is successful.
3895 * remote-nindy.c (nindy_create_inferior): Don't push a new
3896 nindy_ops since nindy uses the same one for execution and memory
3898 * core.c (core_ops): Use child_attach and child_create_inferior
3899 rather than default attach and create_inferior functions.
3901 Handle floating point registers in core files.
3903 * sparc-xdep.c (fetch_core_registers): Rewrite for float support.
3904 * sun3-xdep.c (fetch_core_registers): Rewrite for float support.
3905 This version untested since BFD doesn't yet support sun3 core
3907 * hp300hpux-xdep.c: Rewrite fetch_core_registers to new calling
3908 conventions. Fix comments and style. This version has not
3909 been compiled yet, since we have no HP inhouse.
3910 * core.c (get_core_registers): Look for two sections, ".reg"
3911 and ".reg2", and pass both to fetch_core_registers sequentially.
3913 Revise directory path yet again.
3915 * source.c (forget_cached_source_info): Not static any more.
3916 (init_source_path): New default source path is "$cdir:$cwd".
3917 (dir_command): Handle variable arguments ($cdir, $cwd).
3918 (source_info): Print "Compilation directory" rather than
3919 "Originally compiled in" to remind people of $cdir.
3920 (openp): If the path contains $cwd, use current directory.
3921 (open_source_file): If compilation directory is known, replace
3922 first $cdir in path with the compilation directory.
3923 (print_source_lines): Even if we can't print the lines, set the
3924 current symtab and line for future commands like "info source" or
3925 "breakpoint". Also, error message now contains the file name,
3926 line number, and file access error message.
3927 (_initialize_source): Fix help text to describe changes.
3928 * main.c (cd_command): Forget cached source info when we chdir.
3929 * utils.c (strstr): Add simple implementation.

3933 * coffread.c (read_one_sym, init_linetable, init_stringtab):
3934 Byte-swap COFF symbol tables if necessary when reading them in.
3935 Use complain() to replace error message in one spot. Needs
3936 corresponding change in bfd/coff-code.h to make some symbol
3937 swapping routines non-static.
3939 Mon Mar 4 00:53:40 1991 John Gilmore (gnu at cygint.cygnus.com)
3941 Merge changes from Eirik Fuller, for UTek.

3949 declarations of errno.
3951 * remote-eb.c: Define B19200 and B38400 as EXTA and EXTB.
3953 * remote-vx.c: Include <sys/time.h> for UTek; Sun gets it via
3954 <rpc/rpc.h> and <rpc/types.h>.
3956 Sat Mar 2 15:47:55 1991 John Gilmore (gnu at cygint.cygnus.com)
3958 * i960-tdep.c (examine_prologue): Add new argument limit,
3959 which stops the scan at the end of the prologue, or at the PC.
3960 This fixes a problem where it walks down into the code for the
3961 user's statements if that code looks like function prologues.
3962 Mark Fox and I have been bouncing this code back and forth, making
3963 small changes to it. Callers changed to match.
3965 Tue Feb 26 01:47:07 1991 Cygnus John Gilmore (cygnus at yuba)
3967 Cleanup for gdb-3.94 release final:
3969 * Makefile.dist: Remove remote-vx.c, remote-nindy.c, and all
3970 the .c files from vx-share and nindy-share, from the various
3971 macros, since they are not found via ALLDEPFILES.
3972 (SFILES): Add tm-i960.h.
3973 (alldeps.mak rule): Break out ALLDEPFILES_MAINDIR and
3974 ALLDEPFILES_SUBDIR. List all the nindy and vxworks subdir files
3976 (TAGFILES_MAINDIR): Change ALLDEPFILES to ALLDEPFILES_MAINDIR.
3977 (gdb.tar.Z): Use ALLDEPFILES_SUBDIR as well as SFILES_SUBDIR.

3981 * am29k-tdep.c: Add contribution line.
3982 (examine_prologue): Cache information about function prologues in
3983 the misc-function-vector to avoid lots of references over the
3984 serial line while examining instructions.
3986 * core.c (core_close): New function made from cleanup_core.
3988 * core.c, exec.c, inftarg.c, remote-eb.c, remote-nindy.c,
3989 remote-vx.c, remote.c, target.c, target.h,
3990 Update target_ops vector to add attach, close, and load entries.
3991 Use add_syms_addr_command, not add_file_addr_command, for
3992 add_file. Break out close routine from existing code.
3994 * dbxread.c (really_free_pendings): Don't free pending_blocks;
3995 they are in an obstack.
3996 (read_dbx_symtab): Relocate end_of_text_addr in the psymtab.
3998 (define_symbol): Add symbol type parameter; change callers;
3999 pass type parameter to DBX_PARM_SYMBOL_CLASS macro to allow
4000 it to influence the symbol class on the i960.
4001 (define_symbol): Swap LOC_CONST's into target byte order.
4003 * exec.c (exec_close): New function.
4004 (exec_file_command): Call it.
4006 * findvar.c (read_relative_register_raw_bytes): Doc byte order,
4007 Fix byte order of frame pointer.
4008 (read_var_value): Result of 0 if var's value can't be found,
4009 e.g. missing FRAME_ARGS_ADDRESS. Byte-swap LOC_CONST and
4010 LOC_LABEL values to target order. Add LOC_LOCAL_ARG.
4011 (locate_var_value): Use read_var_value and use its lazy address
4012 as the location of the var's value. Lint.
4014 * i960-pinsn.c (next_insn): Add routine from vxgdb for scanning
4017 * i960-tdep.c (arg_address, i960_frame_find_saved_regs): Remove
4018 obsolete Intel versions in favor of vxgdb versions.
4019 (check_host, byteswap, byteswap_val, reorder_val): Eliminate
4020 code dealing with byte order of values, which Intel did in host byte
4021 order rather than gdb-4's target byte order.
4022 (i960_frame_chain_valid): Move to nindy-tdep.c.
4023 (examine_prologue, skip_prologue, frame_find_saved_regs,
4024 frame_args_address, leafproc_return, saved_pc_after_call,
4025 pop_frame): Add vxgdb versions from Mark Fox.
4026 (examine_prologue, frame_struct_result_address): Add code
4027 to deal with the saved value of G13 (struct return address
4029 (frame_args_address): Modify Mark's version to prefer the
4030 saved value over the current value in the topmost frame.
4031 Cache result in the frame info to avoid performance hair in
4033 (print_fault): Add gdb960 code for printing faults.
4034 (_initialize_i960): Actually call check_host.
4036 * ieee-float.c (ieee_extended_to_double, ieee_double_to_extended):
4037 add stub routines. FIXME, these currently just return zero!
4039 * infcmd.c (program_info): Use PRINT_RANDOM_SIGNAL.
4040 (attach_command): Call target_attach, not target_open, now.
4042 * infrun.c (normal_stop): Make global, not static, for vx_attach.
4043 (child_attach): Rename from child_open.
4044 (wait_for_inferior): Use PRINT_RANDOM_SIGNAL. If stop_pc is zero,
4045 don't confuse it with a zero step_resume_break_address.
4047 * inftarg.c (child_detach): Eliminate inferior_pid test.
4048 (child_files_info): Clean up message a bit.
4049 (child_ops): Use child_attach, not child_open, to attach.
4051 * mem-break.c: #ifdef out the whole file if BREAKPOINT is not
4052 set (e.g. on VxWorks or NINDY). Move read_memory_nobpt from
4053 findvar.c to here, since it depends on the contents of the
4054 shadow_contents of breakpoints, but keep if #if 0 since it is
4057 * nindy-tdep.c: New file, contains nindy_frame_chain_valid, moved
4060 * printcmd.c (address_info): Handle LOC_LOCAL_ARG. Lint.
4061 (ptype_command, display_command): Eliminate have_inferior_p and
4062 have_core_file_p in favor of target_has_stack or
4063 target_has_execution.
4064 (print_frame_args): Handle LOC_LOCAL_ARG. Eliminate duplicate
4065 code for actually finding the values of arguments, though we still
4066 keep track of the maximum stack offset for use in printing unnamed
4067 arguments. Handle missing FRAME_ARGS_ADDRESS.
4069 * remote-nindy.c (i960_print_fault): Move to i960-tdep.c.
4070 (struct nindy_regs): Define registers passed to/from nindy.
4071 (nindy_fetch_registers, nindy_store-registers): Translate between
4072 nindy and GDB formats for the registers.
4073 (dcache_init): Statically allocate the cache, since it was being
4074 allocated by a malloc that was never freed anyway.
4075 (nindy_create_inferior): Error, not core dump, if no exec file.
4076 (nindy_before_main_loop): Use target_load, not target_add_file.
4078 * remote-vx.c (net_load): Specify large timeout for load
4079 requests. Allow user to break out with INTERRUPT.
4080 (net_break): Remove useless code, clean up. Change callers.
4081 (parse-args, skip_white_space, find_white_space): Clean up arg
4082 parsing to cope with quoted strings.
4083 (net_wait, net_quit): Never call error, just return status.
4084 (vx_read_register, vx_write_register): Cleanup status checking.
4085 #ifdef the code based on which CPU we are using (960 or 68k),
4086 FIXME, this should be completely general but it isn't yet.
4087 (vx_xfer_memory, vx_resume): Cleanup status checking.
4088 (vx_run_files_info): Improve message.
4089 (vx_load_command): Renamed from vx_add_file_command. Allow load
4091 (net_ptrace): Remove unused routine.
4092 (vx_wait): Adopt code from vxgdb960 to cope with broken
4093 connections to target machine and prompt to disconnect. Remove
4094 debug printouts. Map some EVENT_'s to SIGnals.
4095 (add_symbol_stub, vx_open): Print names of object files we found,
4096 and "ok" if we read their symbols OK. Clarify output in general.
4097 (vx_attach, vx_detach, vx_kill): Add these commands.
4098 (vx_convert_from_virtual, vx_convert_to_virtual): Simplify.
4099 (vx_run_ops): Turn off all_mem, to avoid spurious msg in the
4100 "info files" output, and create_inferior, since we already have
4103 * stack.c (frame_info): Replace Frame_unknown with 0.
4104 (print_frame_arg_vars): Handle LOC_LOCAL_ARG.
4105 (return_command): Pop until the PC matches as well as the FP,
4106 so it works even if the FP is shared with another function,
4107 as in "frameless" or "leaf" procedures.
4109 * symfile.c (load_command): renamed from add_file_target_command.
4110 (add_syms_addr_command): renamed from add_file_addr_command.
4111 (add_syms_command): Stub to call target_add_syms.
4112 (_initialize_symfile): Change command names and descriptions,
4113 add-file => add-syms, and load from alias to its own command.
4115 * target.c (kill_or_be_killed, maybe_kill_then_attach,
4116 maybe_kill_then_create_inferior): Default for attempts to start
4117 a process, if one is already running, is to ask about killing
4118 it and retry if yes.
4119 (upstack_create_inferior): #if-0 it, strata obsolete it.
4120 (push_target, unpush_target, pop_target): to_close() a target
4121 before unstacking it.
4122 (target_info): Renamed from target_files_info.
4123 (_initialize_targets): Rename "i files" as "i target", accessible
4126 * target.h: Improve comments about the target_ vectored routines.
4128 * tm-i960.h: Remove NINDY-specific stuff to tm-nindy960.h.
4129 Convert commenting style to standard GNU style.
4130 (DBX_PARM_SYMBOL_CLASS): allow LOC_LOCAL_ARG's to be recognized.
4131 (SKIP_PROLOGUE): No longer a no-op.
4132 (SAVED_PC_AFTER_CALL): Now handles leaf procedures.
4133 (*_REGNUM): Sort register numbers.
4134 (REGISTER_BYTES, REGISTER_BYTE, REGISTER_RAW_SIZE,
4135 MAX_REGISTER_RAW_SIZE, REGISTER_CONVERTIBLE,
4136 REGISTER_CONVERT_TO_VIRTUAL, REGISTER_CONVERT_TO_RAW): Float regs
4137 are now 10 byte extendeds, not 8 byte doubles.
4138 (FRAME_CHAIN_VALID): Make this config-dependent, since it differs
4139 for nindy versus vxworks targets. FIXME, this should possibly go
4140 in the target vector.
4141 (EXTRA_FRAME_INFO, INIT_EXTRA_FRAME_INFO): Cache both
4142 frame_saved_regs and arg pointer with each frame.
4143 (FRAMELESS_FUNCTION_INVOCATION): New leafproc support.
4144 (FRAME_ARGS_ADDRESS): Use cached result.
4145 (FRAME_ARGS_ADDRESS_CORRECT): New, avoids g14 guessing.
4146 (FRAME_FIND_SAVED_REGS): Change arg to subsidiary fn.
4147 (PRINT_RAMDON_SIGNAL): Call print_fault.
4148 (POP_FRAME): Now works.
4150 * tm-nindy960.h: Break this off tm-i960.h. NINDY-specific
4151 option parsing and startup; STACK_END_ADDR, FRAME_CHAIN_VALID,
4152 BREAKPOINT, and DECR_PC_AFTER_BREAK are here.
4153 (ADDITIONAL_OPTION_HANDLER): use target_load, not
4156 * tm-vxworks960.h: Break this off tm-i960.h. VxGDB specific
4157 startup; DECR_PC_AFTER_BREAK, and FRAME_CHAIN_VALID are here.
4159 * valarith.c (value_subscripted_rvalue): Avoid handling
4160 floats and doubles specially; it gave alignment errors. Lint.
4162 * valops.c (value_of_variable, value_of_this): Error if unknown
4165 * valprint.c (print_floating): Bcopy rather than pointer-deref,
4166 to avoid alignment problems.
4167 (value_print): Handle unknown value address.
4168 (cplus_val_print): Two args are ignored; remove them. Change caller.
4169 (val_print): Use unpack_long rather than pointer-deref.
4172 (unpack_long, unpack_double): Use bcopy rather than pointer-deref
4173 to avoid alignment problems.
4174 (value_being_returned): Error if return value unknown.
4175 (set_return_value): Add bogosity warning, FIXME. *
4177 * TODO: A woman's work is never done.
4179 * Makefile.dist: Distribute REMOTE_OBS into tconfig files.
4180 Separate INCLUDE_CFLAGS for use with lint. Add LINTFILES.
4181 Add ieee-float.o to OBS.
4182 * tconfig/{nindy960,vxworks68,vxworks960}: Include the desired
4183 REMOTE_OBS remote-interface files in the TDEPFILES and TM_FILE.
4184 * tconfig/i960: FIXME. Half-merge, produce warning if config'd.
4186 Changes to generalize the VxWorks RPC protocol slightly, to handle
4187 i960 as well as 68000.
4189 * vx-share/dbgRpcLib.h (VX_SOURCE_STEP): Add.
4190 * vx-share/reg.h: Produce i960 regs #ifdef I80960
4191 * vx-share/xdr_ptrace.c: Skip FPA registers if 960.
4192 * vx-share/xdr_rdb.h: Add SOURCE_STEP struct and xdr decl.
4193 * vx-share/xdr_rdb.c: Add xdr_SOURCE_STEP routine.
4194 * vx-share/xdr_regs.c: Add xdr_regs, xdr_fp_status, xdr_ext_fp
4195 for i960. Change xdr_vectors to xdr_opaques for 68k registers,
4196 so they will move in target byte order rather than network
4197 byte order (happens to be the same).
4199 Mon Feb 25 03:41:44 1991 John Gilmore (gnu at cygint.cygnus.com)
4201 * tm-convex.h (END_OF_TEXT_DEFAULT): Remove #if 0'd block.
4203 Sun Feb 24 00:55:53 1991 John Gilmore (gnu at cygint.cygnus.com)
4206 Add contribution lines to various files, showing where they
4209 * breakpoint.c (break_insn, check_break_insn_size,
4210 read_memory_nobpt): Remove to mem-break.c.
4212 * xm-*.h, param-no-tm.h, tm-29k.h, valprint.c: Change BYTE_ORDER to
4215 * tm-29k.h (STAB_REG_TO_REGNUM): Warn user if symbol table
4216 entry has bad register number. This change is not
4217 tested in this release, FIXME.
4219 * frame.h: Eliminate Frame_unknown in favor of a simple zero.
4222 * value.h: Force value's contents field to be aligned to hold
4223 at least a double or a long long (if supported). This avoids
4224 doing bcopy's in and out of the contents field.
4226 (step_1): Avoid coredump under obscure circumstances when we
4229 * symtab.h (misc_info): Add field to misc function vector for
4230 any kind of cached information the target code desires. AMD
4231 29000 uses this to avoid repeating examine_function_prologue's.
4233 * coffread.c: Lint. Remove static symfile, read_section_header.
4234 core.c (have_core_file_p): Lint: remove.
4235 expprint.c (print_subexp): Lint.
4236 infptrace.c, valops.c, valprint.c: lint.
4238 Roll in changes from vxgdb-5.0.1:
4240 * symtab.h: Comment byte order of each address class. Add
4241 LOC_LOCAL_ARG for frame-relative args (960).
4242 expread.y: Use LOC_LOCAL_ARG where LOC_ARG is used.
4243 symtab.c, symmisc.c: ditto.
4245 * infrun.c (init_wait_for_inferior): Clear stop_signal.
4247 * remote.c (remote_resume): Error if resume with a signal.
4249 * symfile.c (prim_record_misc_function): Clear misc_info.
4250 (fill_in_vptr_fieldno): Check stub type of arg.
4252 * valops.c (value_cast): Avoid looking up names of types whose
4253 name we don't know, to prevent coredump. Sun CC produces typedef
4254 rtx and the name of *rtx is zero...
4256 Mon Feb 18 21:16:25 1991 John Gilmore (gnu at cygint.cygnus.com)
4258 Roll in changes from final AMD 29000 port (Tiemann).
4260 tconfig/am29k: Add COFF_ENCAPSULATE and TARGET=TARGET_AM29K
4261 for ../include/a.out.encap.h. This might not work now that BFD
4262 is separately compiled. Instead, BFD support for encap will have
4263 to translate machine type 29k into the right COFF_MAGIC.
4265 * infcmd.c: Remove references to inferior_pid that aren't used
4266 in actual ptrace calls; use target_has_execution, etc.
4267 (have_inferior_p): Remove function.
4268 (program_info): Print target info rather than "process number";
4269 avoid gratuitous messages unless from_tty.
4270 (run_stack_dummy, finish_command): Set proceed_to_finish.
4271 infrun.c: Remove inferior_pid refs. Decl & init proceed_to_finish.
4272 main.c: Lint. Lose have_inferior_p().
4273 inferior.h (have_inferior_p): Remove, lint.
4274 (proceed_to_finish): Add flag to ask that all regs be saved
4275 by normal_stop, for the few commands that need it, speeding up
4276 serial I/O. Add comments to stop_registers.
4278 * remote-eb.c: Remove newline from breakpoint message we grep
4279 for. Never time out when running the user program.
4283 Wed Feb 13 15:34:40 1991 John Gilmore (gnu at cygint.cygnus.com)
4285 Roll in changes from vxgdb-5.0.1:
4287 * dbxread.c (read_dbx_symtab): If we encounter a "FORTRAN COMMON"
4288 symbol in its raw form, we are processing an unlinked ".o" file.
4289 See if the target environment has assigned it an address, using
4290 target_lookup_symbol (VxWorks does), and enter it into the symtab
4293 * tm-vxworks.h (FRAME_CHAIN, FRAME_CHAIN_VALID): Override usual
4294 68k versions for a simpler version that assumes zero FP at bottom.
4295 Fixes bug of truncated stack reports.
4297 * target.h (target_lookup_symbol): Define this routine's args
4298 and result, finally.
4300 * target.c (nosymbol): Default routine for target_lookup_symbol.
4301 (target_default): Default lookup_symbol and call_function too.
4302 (files_info): Only print has_all_memory warning if a non-dummy
4305 * remote-vx.c (vx_read_register, vx_convert_to_virtual,
4306 vx_convert_from_virtual): If target does not have floating point,
4307 zero register "values", and avoid doing cross-net conversions.
4308 (vx_lookup_symbol): Rename net_lookup_symbol, add to vectors.
4309 (vx_open): Rearrange code that attaches to target and reads
4310 symbols for all loaded modules, to work if some of the modules
4311 are not accessible. Add symbol_stub() and add_symbol_stub()
4312 as callbacks from catch_errors(). Allow connect attempt to be
4313 interrupted painlessly with ^C (FIXME, there are still some bugs
4314 if the interrupt happens during symbol reading.). Print
4315 final message with puts_filtered, since symbol messages are
4320 * main.c (catch_errors): Only print errstring if non-null.
4321 (command_loop): Avoid an ioctl per command to test ISATTY.
4323 * remote-vx.c (net_load): make static; avoid sophomoric msg.
4324 (vx_xfer_memory): Return correct result!
4325 (vx_files_info): Indicate whether target has float or not.
4326 (vx_lookup_symbol): Complain, not error, if target gone.
4327 (vx_open): Print "Connected" msg before disabling immediate-quit.
4328 [FIXME: lookup_symbol and vx_open changes need testing.]
4330 target.c, remote-eb.c, inftarg.c, am29k-opcode.h, target.h,
4331 tm-29k.h, tmm-vxworks68.h, symfile.c, gdb-int.texinfo: Add
4332 contributor lines and update copyrights to 1991.
4334 Changes from an attempted H-PUX host port:
4336 * infptrace.c (PT_ATTACH, PT_DETACH): Handle HP/UX, which
4337 defines PT_ATTACH and PT_DETACH but not PT_KILL.
4338 * remote-eb.c (eb_open): Misplaced endif kills sysv H/PUX.
4339 * remote-vx.c: include <sys/time.h> for HPUX.
4340 * hp300hpux-xdep.c (fetch_core_registers): Rewrite old
4341 "core_file_command" routine to BFD regime. May not work yet.
4343 Attempted port of "gdb-3.4 Van Jacobson xgdb" to modern gdb.
4345 * xgdb.c: Replace X10 version with some VJ version.
4346 (FIXME: Its copyright assignment is not on record.)
4347 * xgdb.c: Update include files to X11R4 (Xaw crud).
4348 (xgdb_display_source, create_text_widget): fix call to
4349 get_filename_and_charpos. Rewack source window stuff for X11R4
4350 (gleaned from include files, and "nm's" of binary libraries, since
4351 I had no doc available).
4352 (append_selection, append_selection_word): Disable with FIXME
4353 since R4 changed interface here.
4354 (create_buttons): Add back the old set of buttons.
4355 (xgdb_create_window): Fix call to XtInitialize (&argc not argc).
4357 * Makefile.dist (xgdb, xgdb-init.c): Update for X11R4 on Suns.
4358 Roll VERSION to 3.94 (not yet final though).
4360 Sat Feb 9 09:46:25 1991 John Gilmore (gnu at cygint.cygnus.com)
4362 * obstack.h (obstack_ptr_grow, obstack_ptr_grow_fast,
4363 obstack_int_grow, obstack_int_grow_fast): Eliminate
4364 cast on left of assignment, which gives MIPS cc fits and is
4367 * sparc-pinsn.c (print_insn): Eliminate 'set' test, subsumed by
4368 F_ALIAS. Use printf, not fprintf, when not passing a file
4370 (compare_opcodes): Check that identical instructions have
4371 identical opcodes, complain otherwise.
4373 * sparc-opcode.h (st %fsr): Fix opcode "lose" mask. This
4374 was reported by Roland McGrath.
4375 (unimp): Only match if exactly zero instruction. (Roland)
4376 (branches and traps): Generate all variations of these
4377 instructions with macros, based on a single call that defines
4378 each condition name and its binary representation.
4379 (set): Turn on alias bit, to avoid test in sparc-pinsn.c.
4381 * valprint.c (val_print_fields): Take, and use, format parameter.
4382 This means that "p/x struct" again prints the elements in the
4383 desired format. Changed callers.
4385 * stack.c (frame_info): Use filtered output, and indicate wrap
4386 points. Remove kludgy formatting designed to avoid line wrap.
4388 * utils.c (wrap_here): If the line is already full (because
4389 we had printed a long indent or long wrapped string), do an
4390 immediate newline-and-indent.
4392 * m68k-pinsn.c (print_insn_arg): Bugfix from
4393 ntmtv!thompson@ames.arc.nasa.gov (Mike Thompson): 'bkpt #0'
4394 instruction is incorrectly disassembled as bkpt #8.
4396 * dbxread.c (end_psymtab): Bugfix from Peter Schauer
4397 <pesrem@regent.e-technik.tu-muenchen.de>: If you want to set a
4398 breakpoint in a *.y file gdb will say Reading in symbols for *.y...
4399 and then will dump core (sometimes). I traced it back to an
4400 uninitialized symfile_name in psymtab_to_symtab.
4401 (const_vol_complaint): Add quotes to message.
4402 (define_symbol): Only believe line number if gcc_compiled.
4403 Avoid allocating symbol if we will not return it.
4405 Add target strata support so that newly established targets go
4406 into their right place in the target stack (e.g. a new exec file
4407 doesn't wipe out the ability to access the running process).
4409 * target.h, core.c, exec.c, inftarg.c, remote-eb.c,
4410 remote-nindy.c, remote-vx.c, remote.c, target.c: Add to_stratum
4411 and initialize it properly in all the targets.
4413 * target.h: Document strata. Change return type of push_target.
4415 * target.c (nomemory): new function for dummy memory access.
4416 (tcomplain): Rename complain, now also used in symfile.c.
4417 (push_target): Push targets within strata. New return value shows
4418 whether new target is on top of stack or not. Always keep dummy
4420 (target_files_info): Ignore dummy target.
4422 * core.c (core_open): Warn user, and skip accessing file, if the
4423 core target is not the topmost target in the stack.
4424 * remote-nindy.c (nindy_create_inferior): Avoid unpush_target, now
4427 * remote-vx.c: Remove vx_prepare_to_store from vxworks memory
4428 target_ops, it doesn't belong there since we have no regs there.
4429 Change name of target from machine => memory to clarify.
4431 Thu Feb 7 16:32:09 1991 John Gilmore (gnu at spiff.cygnus.com)
4433 * Freeze version 3.93 for release.
4435 * Makefile.dist: Handle vx-share and nindy-share subdirs
4436 properly when building gdb.tar.Z.
4438 * symtab.c: lint; add no_symtab_msg to consolidate the messages
4439 printed in various places, so I could change just one copy.
4441 * dbxread.c, coffread.c: Change references to bfd->iostream
4442 to cast to FILE *, now that BFD avoids needing types defined
4443 in other header files.
4445 Tue Feb 5 21:39:35 1991 John Gilmore (gnu at cygint.cygnus.com)
4447 * command.c, dbxread.c, expprint.c, infcmd.c, infptrace.c,
4448 infrun.c, printcmd.c, remote-nindy.c, source.c, sparc-tdep.c,
4449 sparc-xdep.c, symfile.h, symmisc.c, utils.c, valprint.c: Lint
4450 (actually gcc -Wall).
4452 * dbxread.c: Remove first_global_sym, last_global_sym, since
4453 they are never referenced.
4455 * defs.h (baud_rate): Declare.
4456 main.c: Define it, and add the -b option to set it.
4458 * gdb-int.texinfo: Add text on how to define a new host or target
4459 architecture, prompted by Per Bothner's questions about MIPS
4462 * gdb.texinfo: Document "complaints". Change doc of -q since
4463 gdb no longer prints the copyright and blurb if you specify a file
4464 name to be debugged (just like Emacs). Add doc for Nindy-specific
4465 command line flags for specifying target serial port and such.
4466 Update copyright to 1991.
4468 * gdbcore.h: Remove a large mass of now-useless crud, since BFD
4469 has taken over for us the job of ripping up executable files. The
4470 crud caused Per Bothner's port to not compile.
4472 * infrun.c (normal_stop): Avoid printing "Program exited
4473 normally" if we are in batch mode. This allows a GDB which
4474 executes a program on a target system, to behave like a Unix
4475 command (input from stdin, output to stdout, no extraneous
4478 * main.c (main): Allow additional machine-dependent command line
4479 options to be specified with the ADDITIONAL_OPTIONS,
4480 ADDITIONAL_OPTION_CASES, ADDITIONAL_OPTION_HELP, and
4481 ADDITIONAL_OPTION_HANDLER macros. Also allow machine-dependent
4482 processing to occur just before the main loop with
4483 BEFORE_MAIN_LOOP_HOOK.
4484 (main): If a "core file" argument is specified, and it is not a
4485 core file, try it as a process ID to attach.
4486 (symbol_completion_function): Attempt to cope with
4487 "show screen-" TAB, not very successfully. This needs more work,
4489 (batch_file): New function, returns whether we are reading
4490 commands from an interactive tty on stdin, or from somewhere else.
4491 Called by normal_stop since it doesn't get from_tty passed down
4492 to it like many commands do.
4494 * remote-nindy.c: Handle command line options for nindy
4496 (nindy_before_main_loop): Prompt user for tty name if they
4497 don't specify it before getting to the interactive command loop.
4499 * tm-i960.c: Add ADDITIONAL_OPTIONS, etc, to handle -O, -brk,
4500 and -r command line options. Also add hook before main loop
4501 to make it easy to specify a tty.
4503 * TODO: More things to do, one done.
4505 Mon Feb 4 23:57:39 1991 John Gilmore and Mike Tiemann (at cygint.cygnus.com)
4507 * dbxread.c: Make complaint() calls pass pointer, not struct.
4508 Add complaints about badly formatted C++ type information
4509 (const/volatile indicator, and parse errors resulting in
4510 error_type). Fix C++ virtual member fn comment.
4511 (read_struct_type): Avoid bumping pointer if we got a parse
4512 error; this prevents our walking beyond the end of a string.
4513 Terminate loop on null char as well as semicolon.
4514 (process_one_symbol): Fix the LBRAC fix so that it uses the
4515 last previous SLINE, FUN, or SO record's PC address. C++ debug
4516 symbols did not have SLINE records in a useful order compared
4517 to the LBRAC records.
4518 (define_symbol): Handle "catch" records.
4520 * symtab.c (check_stub_type): Added new complain
4521 `stub_noname_complain' and added a consistency check to
4522 keep the debugger from crashing when finishing from an
4523 exception frame. A real fix will be needed later.
4525 Sat Feb 2 10:43:05 1991 John Gilmore (gnu at cygint.cygnus.com)
4527 * infcmd.c (attach_command): Make global.
4529 * Makefile.dist (REMOTE_OBS): Make these compile by default,
4530 but make them easy to comment out. Perhaps later they should
4531 be enabled by what CPU you configure for? FIXME.
4532 (VERSION): Roll to 3.93.
4533 (pinsn.o): Remove rule for obsolete file.
4534 (dbxread.o,coffread.o,mipsread.o): Use ${srcdir} explicitly.
4536 Run down a problem that manifested by printing the wrong function
4537 name in stack traces of read_ofile_symtab. Turned out that the
4538 problem was the SunOS 4.1.1 (and previous) C compiler outputs
4539 the LBRAC symbol with an address in the *data* segment, which
4540 blew our binary search through the blocks.
4542 * dbxread.c: Use the complain() facility consistently to bitch
4543 about problems in the symbol file we are reading.
4544 (finish_block): Add code to check the nesting of the blocks;
4545 complain and Procrust them to fit if wrong.
4546 (make_blockvector): Check the order of the blocks, complain
4547 [but don't cope] if wrong.
4548 (process_one_symbol): ifndef SUN_FIXED_LBRAC_BUG, check LBRAC
4549 symbols to be sure their PC value is greater than the last SLINE
4550 (line number) symbol we've seen, complaining and adopting the
4551 SLINE PC value if wrong.
4553 * symfile.h (struct complaint, complaint_root, complain,
4554 clear_complaints): Add.
4555 * symfile.c (complain, complaint_root, clear_complaints): Add
4556 facility to deal with non-fatal complaints and to regularize their
4558 (symbol_file_add): Clear complaint counters to allow new complaints.
4559 (initialize_symfile): Add 'set complaints' and 'show complaints'.
4561 * dbxread.c (dbx_symfile_read): Remember the address and size
4562 of the string table for the main symbol file, so we won't read it
4564 (dbx_psymtab_to_symtab): Fix the check for main symbol file,
4565 to avoid reading the string table yet again. Lint.
4566 (throughout): Improve filtered output, including word wrap.
4567 (read_range_type): Improve Bothner's fix to handle other types too.
4569 * utils.c: Improve line wrap implementation. Handle unlimited
4570 width by making chars_per_line unsigned.
4571 (puts_filtered): New, easy, function.
4573 * defs.h (puts_filtered): add.
4575 * mipsread.c (compare_symbols, sort_symtab): Remove these fns,
4576 call the identical sort_symtab_syms() in symfile.c instead.
4578 * expread.y: Suggest the `file' command rather than `symbol-file'.
4580 * command.h (enum var_types): Add zinteger for seroable
4582 * command.c (do_setshow_command): Handle var_zinteger. Restructure
4583 nested if's into a switch.
4585 * breakpoint.c (bpstat_print): If bpstat "print" flag is not set,
4586 we did not stop because of a breakpoint (it must have been for
4587 some other reason, like a "stepi"), so don't print anything.
4589 * symtab.c: Include <sys/types.h> all the time. Now that BFD
4590 doesn't include <sys/types.h>, old SunOS's require it for
4593 Sat Feb 2 10:39:15 1991 Per Bothner (bothner@cs.wisc.edu)
4595 A test port of gdb-3.92.6 to the Sony NEWS.
4598 Don't normally link in remote- or vx stuff.
4599 Some of it doesn't compile, and it wastes space for 99% of the users.
4600 Remove reference to no-longer-used HAVE_VPRINTF.
4601 Fixed BFD_DEP typo to BFD_DIR.
4603 Fix cast in arg to bfd_h_getlong.
4604 Make char *prefix be const.
4605 Fix how certain range types are mapped into builtin unsigned int types.
4607 Remove 2 #includes. They cause errors (on Sony, at least),
4608 and aren't needed (they wern't in earlier versions).
4610 print_address_symbolic should never demangle labels
4611 (since it prints *assembler-level* labels).
4613 [This was superseded by the change to printcmd below.]
4616 Add some "volatile" return types to avoid warnings.
4617 If MISSING_VPRINTF add vprintf function and not just macro
4618 (since vprintf is used in printcmd.c).
4620 Unless __GNUC__, use obstack_grow instead of obstack_ptr_grow.
4621 (The latter isn't grokked by some PCC-based compilers.)
4623 [This change is in abeyance, we prefer to fix obstack_ptr_grow.]
4625 Make chunk size of dont_print_obstack 32*4 instead of default 4096.
4626 * nindy-share/coffstrip.c
4627 Added some forward declarations (otherwise, gcc complains
4628 about implicit extern redefined as static).
4630 Sun Jan 20 02:38:19 1991 John Gilmore (gnu at cygint.cygnus.com)
4632 Changes inspired by Per Bothner:
4633 * printcmd.c (print_address_symbolic): Take additional parameter
4634 specifying whether to demangle.
4635 (print_address): Pass in asm_demangle to control demangling.
4636 (print_address_demangle): New fn, takes explicit arg to control
4638 * utils.c: Add new vars demangle and asm_demangle, and let them
4640 (fputs_demangled): If !demangle, just print the argument.
4641 (fprint_symbol): If !demangle, just print raw symbol.
4642 * valprint.c (val_print): Call print_address_demangle rather than
4643 print_address, to cause demangling to depend on the global
4644 rather than assembler-level demangling setting.
4645 * WHATS.NEW, gdb.texinfo: Document.
4647 * main.c (show_command): Show all settings if no arg.
4648 (initialize_main): Make "info set" the same as naked "show".
4649 * command.c (cmd_show_list): Handle prefix commands in the
4650 list, and print the name of the setting as well as its English
4651 description and value.
4653 Allow gdb functions to specify where a line should wrap if it
4654 exceeds the size of a terminal line. Use it to make the output
4656 * utils.c (set_screen_width_command): New fn, mallocs a buffer
4657 of the right size when screen width changes.
4658 (set_screensize_command, screensize_info): Remove #if 0'd fns.
4659 (wrap_here): New fn, indicates a point in the output where we
4660 should wrap the line rather than just letting it overflow at a
4662 (fputs_filtered): Implement wrapping.
4663 (n_spaces): New fn, returns a pointer to N spaces.
4664 (print_spaces_filtered): Use n_spaces.
4665 * defs.h (n_spaces): Declare.
4666 * stack.c (print_frame_info): Wrap with 4-space indent after
4667 fn name and before filename and line number.
4668 * printcmd.c (print_frame_args): Wrap with 4-space indent
4669 before each argument name is printed.
4670 * valprint.c (value_print): Wrap with no indentation before
4672 (val_print_fields): Wrap with indentation relative to nesting
4673 level before each field name.
4674 (val_print): Wrap with nesting indentation before array elements.
4675 * command.c (do_setshow_command): Avoid extra newlines,
4676 wrap with 4-space indent around values printed, end with period.
4677 * WHATS.NEW, gdb.texinfo, gdb-int.texinfo: Document.
4679 * breakpoint.c (breakpoint_1): Implement addressprint for
4680 "info breakpoints" display. Change file name and line number
4681 format to " at file:nnn" rather than " (file line nnn)".
4682 * gdb.texinfo: Document.
4685 Fri Jan 18 07:21:25 1991 John Gilmore (gnu at cygint.cygnus.com)
4687 Frozen for gdb-3.92.6 release.
4689 README, WHATS.NEW: Update for 3.92.6 release.
4691 tconfig/{altos, i386v, i386v32, m88k, umax}: Eliminate
4692 coffread.o from configs since it is now built by default.
4693 tconfig/{3b1, altosgas, arm, convex, hp300bsd, hp300hpux,
4694 i386v-g, i386v32-g, isi, merlin, news, news1000, np1, pn,
4695 pyramid, symmetry, vax, vxworks68}: Eliminate dbxread.o
4696 from configs since it is now built by default.
4698 Makefile.dist: Update for release 3.92.6. Handle files that
4699 have been moved to ../include, ../getopt, or ../bfd. Add
4700 saber.suppress and tests directory. Add config.status to
4701 the release (it will say "none").
4703 coredep.c: Minor formatting fixes.
4705 These changes were made in early December but only checked in now:
4706 * nindy-share/Onindy.c, nindy-share/coffstrip.c,
4707 nindy-share/nindy.c: lint
4708 * nindy-share/nindy.c (ninStopWhy): Don't byteswap the
4709 register values coming back from the target; we store values
4710 in target byte order everywhere.
4712 Wed Jan 16 19:01:37 1991 John Gilmore (gnu at cygint.cygnus.com)
4714 * am29k-opcode.h, am29k-pinsn.c: Add 29050 opcodes.
4716 * valprint.c (cplus_val_print, val_print_fields): New functions,
4717 which print C++ objects. They conspire to avoid printing a
4718 virtual base class more than once, following all the twists and
4719 turns of C++ virtual base rules.
4720 (val_print): Call the above rather than do it by hand.
4722 * symfile.c (symbol_file_add): Only reset symfile_mtime for main
4723 symbol file, not for added files like shared libs. This really
4724 needs to be generalized to a timestamp per file.
4726 * core.c (cleanup_core): Avoid coredump if no core file.
4728 * config.gdb: Accept -host or -target in place of +host or
4731 * coffread.c (find_linenos): Avoid desupported BFD interface
4732 to line numbers. We still read them manually rather than using
4733 BFD's "generic" features.
4735 * gdbrc.tex, threecol.tex: Add GDB reference card and its
4737 Makefile.dist: Add refcard to OTHERS list for creating tar files.
4739 * Makefile.dist: Eliminate use of $< in explicit targets.
4741 * readline/Makefile: Use $< rather than $*.c, which does not
4742 include the VPATH in GNU Make.
4744 * tconfig/i960-bout, tconfig/i960-coff: These are identical
4745 copies of tconfig/i960, added for global configuration
4746 compatability. All i960 versions can read both coff and b.out.
4748 * tm-88k.h: Fix multiline macro that lacked \'s. Remove
4749 COFF_FORMAT and COFF_CHECK_X_ZEROES since these are now handled
4752 * TODO: Think of more things to do.
4754 Wed Jan 2 19:09:29 1991 John Gilmore (gnu at spiff.cygnus.com)
4756 tconfig/{am29k,i960,sun2*,sun3*,sun4*}: Eliminate config
4757 of sdb versus dbx debug symbols. Add kludge for 68881 80-bit to
4758 64-bit float conversion.
4760 tconfig/sun4, tconfig/sun3, xconfig/sun4, xconfig/sun3: Make
4761 equivalent to sun?os4 so global config works.
4763 Wed Jan 2 18:20:51 1991 John Gilmore (gnu at spiff.cygnus.com)
4765 Fix from Eberhard Mattes <mattes@azu.informatik.uni-stuttgart.de>
4767 * main.c: Only declare linesize once; declare pagesize not at
4768 all, since it is never used.
4769 (main): Clear newly allocated line before it is used.
4771 Fri Dec 28 00:13:42 1990 John Gilmore (gnu at cygint)
4773 Further stabilization for the Intel 960.
4775 * Makefile.dist: Parameterize the location of the "include"
4776 and "bfd" directories, as well as "getopt". Add symfile.c.
4777 Link in both dbxread and coffread. Fix up "make depend" to
4778 rewack the locations of include, bfd, and getopt in its output.
4780 * README: Document moving include files, improve some of
4783 * coffread.c: Move common code out to symfile.c. Change
4784 symbol_file_command style interface to use new *_symfile_init
4785 and *_symfile_read interface under BFD. Use BFD internal
4786 info to locate line table, symbols, etc.
4788 * core.c (core_fetch_registers): Rename to get_core_registers
4789 to avoid confusion with fetch_core_registers.
4790 (register_addr): Move to coredep.c, which is already machine
4791 dependent. This leaves core.c pretty clean of dependencies.
4793 * coredep.c (register_addr): Accept this routine from core.c.
4795 * dbxread.c: Move common code (with coffread.c, etc) into new
4796 symfile.c. Each psymtab now contains a pointer to the
4797 format-dependent function that knows how to read it in. Make
4799 (dbx_psymtab_to_symtab): Renamed from psymtab_to_symtab_2.
4800 (process_one_symbol): Add code to complain about a "compiler bug
4801 we muzzle here", if we actually see it.
4803 * eval.c (evaluate_subexp): Insert missing "break" statements
4804 in code that determines whether a variable is an lvalue in
4805 memory, register, or whatever. I detected this via a compiler
4806 bug in which it *almost* mashed out the whole switch statement.
4808 * gdb-int.texinfo: Add minor sections on configuring gdb for
4809 release, and about the README file.
4811 * infcmd.c (registers_info): Fix formatting somewhat. Still
4812 not as pretty as before, but it handles byte swapping.
4814 * remote-nindy.c: If data cache routines are interrupted while
4815 waiting for the remote end, be sure that any uninitialized cache
4816 blocks are on the free list, not on the valid list!
4818 * symfile.h: Flesh out this header file with all the various
4819 routines and variables that have been merged in from dbxread.c
4820 coffread.c, and symtab.c to symfile.c.
4822 * symfile.c: New file, containing code common to dbxread.c,
4823 coffread.c, and some code from symtab.c. All generic code for
4824 reading symbol files should be in here now.
4825 (unrecord_misc_function): Remove unused function.
4827 * symtab.h: Remove file-reading things to symfile.h.
4829 * symtab.c: Remove file-reading things to symfile.c.
4831 * tm-i960.h: Fix FRAME_CHAIN types; define PRINT_RANDOM_SIGNAL
4832 to decode i960 fault types.
4834 * target.h, remote.c, remote-eb.c, remote-vx.c, remote-nindy.c,
4835 target.c: Change type of the "resume" function from int to void,
4836 since its result was never used.
4838 Sat Dec 22 02:51:40 1990 John Gilmore (gnu at cygint)
4840 * main.c: Replace "stupid" with "caution"; you now "set caution
4843 * printcmd.c (print_scalar_formatted): Fix typo in 'g' format
4845 * infcmd.c (do_registers_info): Call val_print to deal with the
4846 byte order of the registers being printed. FIXME, this makes
4847 the formatting of the output uglier.
4849 * infcmd.c (wait_for_inferior): If PRINT_RANDOM_SIGNAL is
4850 defined, call it for signals the debugger doesn't itself use.
4851 The i960 uses this for more detailed fault information.
4853 * remote.c (remote_open): If arg is null, print help rather than
4856 * sparc-xdep.c (register_valid): Avoid declaring size, since
4857 various modules will think of various sizes depending on the
4858 architecture of their tm-file. FIXME, we need protection against
4859 actually entering one of those modules, which would clobber
4860 storage if not for the target architecture compiled into gdb.
4862 * stack.c (up_command, down_command): Always print the frame
4864 (up_silently_command, down_silently_command): New commands
4867 * i960-pinsn.c (reg), i960-tdep.c: Lint.
4869 * i960-tdep.c (i960_frame_chain_valid): Lookup_symbol now takes
4870 more parameters than it used to.
4872 * findvar.c (registers): Increase slop to 256 bytes, which should
4873 protect us against even most RISC machines with large register
4875 (locate_var_value): Move declaration inside related ifdef.
4877 * remote-nindy.c (): Use TIOCSETN rather than TIOCSETP
4878 throughout, to avoid throwing away buffered input from the board.
4879 (nindy_wait): Supply_register takes addr_of_value, not value.
4880 (i960_print_fault): Renamed from i80960_fault.
4881 (nindy_fetch_registers): Avoid have_regs stuff, just get them.
4882 (nindy_store_registers): Avoid regs_changed stuff, just stuff
4884 (nindy_create_inferior): Don't bother to write PC_REGNUM since
4885 we can set the PC in the call to proceed(). Unpush nindy_ops
4886 before pushing it on top, to avoid message to user. Eliminate
4887 commentary from Unix machines that just misleads here.
4888 (reset_command): Fix error message to suggest target command.
4890 Wed Dec 19 11:03:56 1990 John Gilmore (gnu at cygint)
4892 Release 3.92.5 as frozen.
4894 Stabilize the merged release...with help from lint, Saber C,
4897 Everywhere: Add include files needed to declare return types
4898 of functions called.
4900 * gdb.texinfo: Roland Pesch is documenting gdb, glory be!
4902 * breakpoint.h: Add undeclared breakpoint functions, and some
4903 functions for display handling since I couldn't think of a better
4906 * breakpoint.c (insert_breakpoints): Make code for disabling
4907 shared library bkpts more likely to work. It's used when we
4908 rerun a program and stop before the shared library has been
4910 (breakpoint_cond_eval, bpstat_stop_status): Pass arg as int,
4911 cast from pointer, so it squeezes through catch_errors.
4912 (bpstat_stop_status): Fix logic broken some time ago. We now
4913 always create a bpstat if the stop address matches a breakpoint,
4914 even if we don't stop there -- just like the old code used to do
4915 before I got my fingers into it (sigh).
4916 (breakpoint_1): Print "ignore count" after "stop only if"
4917 condition, since that's how it actually works.
4918 (mention): Handle watchpoints as well as breakpoints.
4919 (watch_command): use set_raw_breakpoint and mention to do most
4920 of the work (and initialize all the fields!). Only pass one
4921 arg to parse_c_expression, since that's all it takes.
4923 * command.c (not_just_help_class_command): Rename arg to args
4924 since we ignore "unused argument" warnings on vars named "args".
4925 inflow.c (child_terminal_info): ditto.
4926 infptrace.c (kill_inferior): ditto
4927 main.c (catch_errors, version_info, quit_command, pwd_command,
4928 source_command, dump_me_command, editing_info,
4929 set_history_size_command, set_history, show_history,
4931 stack.c (locals_info): ditto
4932 target.c (target_files_info): ditto
4933 valprint.c (set_input_radix, set_output_radix): ditto
4935 * core.c: Remove old variables for handling core and exec file
4936 sections (data_start, data_end, stack_start, stack_end,
4937 reg_stack_start, reg_stack_end, reg_stack_offset, text_start,
4938 text_end, exec_data_start, exec_data_end, text_offset,
4939 exec_data_offset, data_offset, stack_offset). They're
4940 superseded the more general build_section_table and
4942 (get_exec_file): Mention the `file' command.
4943 (read_memory_check): Rename to memory_error, and only call it
4944 in the case of an actual error.
4945 (read_memory, write_memory): call memory_error.
4946 (core_fetch_registers): Register section name is ".reg".
4948 coredep.c: Remove a bunch of crud now that all this file does
4949 is pull the registers out of a core file.
4950 (fetch_core_registers): Rewrite to actually work, I hope.
4952 dbxread.c: Use a.out.gnu.h, not system a.out, now.
4953 Replace index() with strchr(). Remove all the pre-BFD macro
4954 definitions for accessing the symbol file.
4955 (struct dbx_symfile_info): Encapsulate the information that
4956 dbx_symfile_init needs to pass to dbx_symfile_read in this
4959 (dbx_new_init, dbx_symfile_init, dbx_symfile_read,
4960 dbx_symfile_discard): Rearrange symbol file reading to divide
4961 the format-specific part from the format-independent part,
4962 leaving the format-independent part such as file name expansion
4963 and opening in symtab.c. This replaces
4964 partial_symbol_file_open and partial_symbol_file_read.
4965 Symbol_file_read, add_file, add_file_target_command,
4966 add_file_addr_command move to symtab.c. Pass an explicit
4967 "mainline" flag for when reading the main symbol table, rather
4968 than relying on the offset address to be zero or nonzero.
4970 (dbx_symfile_read): Don't allow void *'s to be printed as
4972 (SWAP_SYMBOL): Use bfd routines to byte-swap the symbols.
4973 (ADD_PSYMBOL_TO_LIST): Make the "function call rather than
4974 macro" debug version really work.
4975 (read_dbx_symtab): Remove unref'd parameter inclink.
4976 Avoid swapping N_SLINE symbols, for speed.
4977 Merge N_TEXT!N_EXT case with the other external symbol
4978 definitions' case. Add comments.
4979 (start_psymtab): Allocate the symfile name in the psymtab on
4980 the psymbol_obstack, rather than using the caller's storage.
4981 (end_psymtab): Only allocate a dependencies list if there are
4983 (psymtab_to_symtab_2): Use BFD when reopening file to read
4984 its symbols for real.
4985 (read_struct_type): Add FIXME comments where it needs work
4987 (read_huge_number): Add FIXME about overflows.
4988 (read_range_type): Add FIXME about comparing a long to 1<<32.
4990 * coffread.c: Minor changes to move things closer to the new
4991 regime with symtab.c and dbxread.c Major work is still needed
4994 * exec.c (exec_file_command): Remove old variables (see core.c
4996 (xfer_memory): If memory transfer is right at the end of a
4997 section, don't lose.
4999 * findvar.c (get_saved_register): If value is in a real
5000 register, LVAL is lval_register, not lval_memory.
5002 frame.h: Declare print_sel_frame and record_selected_frame.
5004 gdb-int.texinfo: New file, for GDB internals documentation.
5005 Very simple, unformatted doc of cleanups is there for now.
5007 gdbcore.h: Remove obsolete variables that described a.out
5008 section addresses and offsets. (See core.c above.)
5009 Declare fetch_core_registers and registers_fetched.
5011 getopt.c: Declare char *alloca(); even on SPARC.
5013 infcmd.c (run_command): Call target_kill rather than
5015 (step_command, next_command, stepi_command, nexti_command):
5016 Declare from_tty parameter even though we don't use it.
5017 (run_stack_dummy): argument BUFFER is a char array, not
5018 a pointer to REGISTER_TYPE.
5019 (finish_command): using_struct_return needed a value *,
5020 not a struct symbol *.
5022 * infptrace.c (child_xfer_memory): To avoid dependency on
5023 where sections are in memory, try PT_WRITE_D and if that fails,
5024 try PT_WRITE_I. Most Unixes don't care which you use.
5026 * infrun.c (step_resume_break_shadow): Change to array to
5027 match other breakpoint shadow storage.
5028 (clear_proceed_status): Pass address of bpstat to
5029 bpstat_clear, not the bpstat itself.
5030 (child_create_inferior): FIXME comment about if the child
5032 (start_inferior): Remove old function.
5033 (child_open): Use target_kill rather than kill_inferior.
5034 (wait_for_inferior): Ditto.
5035 (insert_step_breakpoint, remote_step_breakpoint): Use
5036 new step_resume_break_shadow.
5038 * inftarg.c (child_wait): If all child processes die,
5039 pretend that the one being waited for exited with signal 42.
5041 * main.c (command_line_input): When scanning for comments,
5042 don't coredump on unclosed quotes.
5043 (quit_command): Use target_kill rther than kill_inferior.
5044 (_initialize_main): Rename class_user from "user" to
5047 * printcmd.c (print_command_1): Initialize "fmt" if no format
5048 is specified by the user.
5049 (print_frame_args): Only add to args_printed if we are
5050 actually fetching args from the stack (avoiding undefined
5052 (_initialize_printcmd): Remove bogus \{ from string.
5054 * remote-eb.c (eb_open): Avoid coredump on no argument.
5056 * remote-nindy.c: Bring out of Intel environment into new
5057 target environment. Remove all conditional compilation on
5058 I80960. Massive hacking throughout.
5059 (nindy_xfer_inferior_memory): New routine stolen from
5061 (nindy_create_inferior): New routine pieced together, probably
5062 not quite working yet.
5063 (nindy_ops): New target_ops struct for nindy.
5065 * remote-vx.c: Use write_memory rather than target_write_memory
5066 to get error checking.
5067 (vx_add_file_command, vx_open): Use symbol_file_add rather than
5069 (vx_create_inferior): Use target_terminal_ours...
5071 * signame.c (_initialize_signame): Always initialize, since
5072 we need the table for things other than psignal.
5074 * solib.c (solib_add): Use symbol_file_add, not add_file.
5075 (solib_address): Return boolean result rather than struct
5076 pointer which nobody else knows the type of.
5078 * sparc-tdep.c, valops.c: Use write_memory rather than
5079 target_write_memory, to get error checking.
5081 * stack.c (locals_info, catch_info, args_info,
5082 get_selected_block, frame_command, up_command): Use
5083 target_has_stack, rather than have_inferior_p or
5086 * sun3-xdep.c (fetch_core_registers): Rewrite for new BFD regime.
5088 * symfile.h: New file, defining the interface between the
5089 generic and object-file-specific symbol reading code.
5091 * symtab.c: Move generic symbol-reading interface to symtab.c,
5092 from dbxread.c, coffread.c, mipsread.c, etc. Add symtab_fns
5093 table to map BFD targets to symbol-reading modules in GDB.
5094 Change index to strchr.
5095 (lookup_struct_elt_type): Use error() rather than hand-made
5096 simulations thereof.
5097 (lookup_partial_symbol): Speedup slightly when length == 0.
5098 (symbol_file_add): New function.
5099 (symbol_file_command): Call it.
5100 (symfile_open, symfile_init): New function.
5101 (add_file_target_command, add_file_addr_command): moved from
5104 * target.c (target_command): use target_kill.
5106 * target.h (target_files_info): Don't declare, never called
5109 * tm-sun2.h, tm-sun3.h (STACK_END_ADDR): Use system include
5110 files to determine stack end address.
5112 * valarith.c (value_x_binop, value_x_unop): Change error message
5113 to be more useful. Pass proper argument to value_struct_elt.
5115 * valops.c (value_assign): FIXME comment that long long
5116 bitfields will break here.
5118 * Makefile.dist: Add symfile.h, remote-nindy.c, remote-eb.c.
5119 Update `make saber_gdb' to work better.
5121 * TODO: A woman's work is never done.
5123 * cplus-dem.c, environ.c, inferior.h, infrun.c, inftarg.c,
5124 main.c, obstack.c, printcmd.c, remote-eb.c, remote-nindy.c,
5125 remote-vx.c, remote.c, solib.c, source.c, sparc-pinsn.c,
5126 sparc-tdep.c, sparc-xdep.c, symmisc.c, symtab.c, symtab.h
5127 target.c, terminal.h, tm-sparc.h, tm-sunos.h, utils.c,
5128 valops.c, valprint.c, exec.c: Lint.
5131 Wed Dec 12 23:44:15 1990 John Gilmore (gnu at cygnus.com)
5133 Continuing Intel 960 port merge of GDB.
5135 * Makefile.dist: Merge i960 "nindy-share" files. Rename
5136 malloc.h to gmalloc.h to avoid name conflicts in /usr/include.
5137 Don't ship gdb.dvi in tar file. Link gdb with init.o, not init.c.
5138 Wack over "make depend" so it handles files in subdirectories
5139 vx-share, nindy-share, bfd, and in the current directory.
5141 * blockframe.c (get_prev_frame_info): Remove fatal error
5142 if stack not defined.
5144 * core.c (core_open, core_detach): New functions that handle
5145 the old "core-file" command as "target core" and "detach" instead.
5146 (core_file_command): Call them.
5147 (core_xfer_memory): Use common routine xfer_memory.
5149 * dbxread.c: Include a.out.gnu.h, not system a.out.h.
5150 dbxread now uses bfd for everything but symbol reading itself.
5151 BFD internals are used to drag out the relevant file offsets.
5152 (partial_symbol_file_open): Change args all around for BFD.
5154 * symtab.c: Rename "value" to "val" everywhere, so we can
5156 (symbol_file_command): New command, moved from dbxread.c
5157 and coffread.c. It uses BFD to read the file, then vectors
5158 based on its type, to dbx or coff symbol readers.
5159 * symtab.h: Extern a few vars for symbol_file_command.
5161 * target.h: Breakpoint takes a char * save area, not a char **.
5163 * valprint.c (val_print): When unpacking bitfields, offset
5164 the address in gdb of the value, if it is declared with a shorter
5165 type. Remove the last "runtime kludge test" of host byte order.
5167 * utils.c: Remove old my_bfd_read routine.
5169 * stack.c (frame_info): Use target_has_stack. Print program counter
5170 register's actual name rather than "pc", since it's called the
5171 "ip" (instruction pointer) on the i960 (sigh).
5173 * target.c (target_command): Add command for selecting a target
5174 type and calling its open routine. This is used for initiating
5175 communication with a particular target, in a generic way.
5177 * tm-i960.h: Update for modern gdb. Remove semicolons from
5178 various macros. Handle reading struct return convention, and
5179 error-out attempts to return structs with the "return" command.
5180 Be sure gdb doesn't think we know how to call functions in the
5183 * i960-tdep.c: Rename FRAME_CHAIN_VALID and FRAME_FIND_SAVED_REGS
5184 to i960_xxx in lower case.
5185 (arg_address): Circumvent errors due to LOC_ARG_BLOCK
5186 not being defined yet.
5188 * remote.c (remote_open): Call start_remote to initialize
5189 wait_for_inferior during open.
5190 (remote_xfer_inferior_memory): Return length written rather
5193 * remote-vx.c (target_command -> vx_open): Use new generic
5195 * remote-eb.c, inftarg.c, exec.c: ditto.
5197 * infrun.c: Fix comments.
5198 (attach_program -> child_open): Use new generic target command.
5199 (wait_for_inferior): Clear saved register values before target_wait,
5200 so target_wait can set some of them if convenient.
5202 * infptrace.c (fetch_inferior_registers, store_inferior_registers):
5203 Return success indicator, not void.
5204 (child_xfer_memory): Avoid fetching initial word if we'll
5205 overwrite it anyway.
5207 * infcmd.c (attach_command): Use new generic target open routine.
5208 (_initialize_infcmd): Update doc on attach and detach commands.
5209 (do_registers_info): Merge in a byte-order problem as a FIXME
5212 * findvar.c (find_saved_register): Avoid problem in current frame.
5213 (read_relative_register): Ditto.
5214 (write_register): Convert byte order on the way out.
5216 * exec.c (file_command): Add.
5217 (add_to_section_table, exec_command): Use new bfd_map_over_sections.
5218 (xfer_memory): Common function between core_xfer_memory and
5220 (exec_xfer_memory): Use it.
5222 * pn-opcode.h: Document that a "PN" is a Gould PowerNode.
5224 * breakpoint.c, breakpoint.h, symtab.h, value.h, frame.h, utils.c,
5225 valops.c, stack.c, target.c, sparc-xdep.c, source.c, printcmd.c,
5226 infcmd.c, i960-pinsn.c, eval.c, defs.h: lint and gcc -Wall.
5228 Sun Dec 2 16:45:06 1990 John Gilmore (gnu at cygnus.com)
5230 Merge Intel 960 port of gdb, continuing...
5232 * dbxread.c (partial_symbol_file_open, partial_symbol_file_read,
5233 symbol_file_command): Pass from_tty arg to hush 'em up.
5235 * coffread.c (symbol_file_command): Avoid output if from_tty != 1.
5236 Add magic numbers for 960 COFF format.
5238 Fri Nov 30 09:18:20 1990 John Gilmore (gnu at cygnus.com)
5240 Merge Intel 960 port of gdb, from Intel "1.2" release.
5242 CHANGE_LOG entries from their port, which was based on
5245 Thu Sep 6 11:02:22 PDT 1990
5246 Remove temp file if download is interrupted.
5248 Wed Aug 1 09:08:33 PDT 1990
5249 Now uses binary protocol to talk to NINDY.
5250 Old hex protocol (NINDY 2.13 and older) supported with -O switch.
5251 Times out after 5 seconds when trying to talk to NINDY.
5253 Tue May 29 12:54:49 PDT 1990
5254 Added variable baud rate (-b switch).
5255 Source code reorganization.
5257 Thu Apr 26 11:09:55 PDT 1990
5258 More cleanup of batch mode; specifically, execute "-s", "-e", and
5259 "-se" switches as soon as they are encountered on the invocation line.
5261 Fri Apr 20 13:47:15 PDT 1990
5264 Thu Apr 19 09:54:28 PDT 1990
5265 Add 'reset' command.
5267 Wed Apr 18 09:48:07 PDT 1990
5268 After opening remote tty, wait for 1 second to go by without input
5269 from it before trying to talk to NINDY (fixes problems with the
5270 Heurikon HK80/V960E).
5272 Mon Apr 4 16:33:05 PDT 1990
5273 Some output was not being suppressed in 'batch' mode.
5275 Thu Mar 22 15:31:11 PST 1990
5276 Ask user if old symbol table should be deleted when new file is
5279 Allow user to run a program downloaded before gdb960 was brought up.
5281 Correct "exec-file" help message for i80960 context.
5283 Correct bug in calculating user space address: could occasionally
5284 corrupt user program.
5286 Make sure to zero low-order bits in rip's because of bug in 960CA
5287 A-step part: could cause operation faults when "next"ing across
5290 Correct bug that made it impossible to get source line numbers for
5291 code loaded at addresses higher than 0x7fffffff.
5293 Wed Jan 10 12:43:22 PST 1990
5294 Open remote tty for exclusive use.
5296 Fri Jan 5 12:14:42 PST 1990
5297 Correct disassembly (CA manual was right after all):
5298 opcode for sysctl is 0x659
5300 Mon Oct 23 12:03:04 PDT 1989
5301 Use G960BASE and G960BIN environment variables to find 'sx' utility.
5303 Mon Oct 16 14:15:09 PDT 1989
5304 "sfr0"-"sfr31" should have been named "sf0"-"sf31"
5306 Mon Oct 2 15:56:31 PDT 1989
5308 Added 960CA disassembly support.
5310 To simplify maintenance:
5311 - eliminated use of symblic links on pinsn.c: use i960-pinsn.c
5313 - eliminated opcode.h: incorporates tables into i960-pinsn.c
5314 - moved 960-specific routines from i960-pinsn.c to i960-md.c
5315 - made disassembly interface identical to that in gdmp960.
5319 Wed Nov 28 21:32:48 1990 John Gilmore (gnu at cygint)
5321 * target.h: Allow targets to stack. Add target_has_memory,
5322 _registers, etc. Restructure memory access and "info files"
5323 to walk the target stack.
5324 * exec.c, core.c, inftarg.c, remote.c, remote-vx.c, remote-eb.c,
5325 target.c: Change tables to match target.h.
5326 * inflow.c (child_mourn_inferior): pop child_ops.
5327 (generic_mourn_inferior): Use new has_stack flag.
5328 * infptrace.c (child_xfer_memory): New memory regime.
5329 * inftarg.c (child_files_info): New "info files" regime.
5330 * remote-eb.c: New memory regime, new info files.
5331 * remote-vx.c: New memory regime, new info files. Now use
5332 separate targets for VxWorks attachment to machine, and
5333 actually running a process under VxWorks, since one has
5334 stack & execution & regs and the other doesn't.
5335 * remote.c: New memory regime, new info files.
5336 * sparc-xdep.c (fetch_core-registers): New memory regime.
5337 * target.c: New routines and support for stacked targets,
5338 new memory regime, new info files regime.
5341 Generalize section handling for an arbitrary number of sections,
5342 including use of the new BFD (binary file) library.
5343 * gdbcore.h: Add struct section_table.
5344 * exec.c (build_section_table): Iterate all sections and
5345 record what gdb needs to know about them.
5346 (exec_command): Use it.
5347 (exec_xfer_memory): Use the table.
5348 (exec_files_info): Print the table.
5349 * core.c (core_file_command, core_xfer_memory, core_files_info):
5351 * source.c (find_source_lines): Use bfd_get_mtime.
5352 * dbxread.c: Quick changes to make it compile with new BFD.
5353 * utils.c (error): Avoid using bfd_error in generic routines.
5355 * core.c (core_fetch_registers): Get from the ".regs" section of
5357 * sparc-xdep.c (fetch_core_registers): Use the .regs info.
5359 * inferior.h (attach_flag): Export.
5360 * infcmd.c (run_command): use new target_create_inferior.
5361 * infrun.c (child_create_inferior): Don't return result.
5362 * Makefile.dist (VERSION): 3.91.4.
5364 Fri Nov 23 28:15:38 1990 John Gilmore (gnu at cygint)
5366 * breakpoint.c (bpstat_num): Handle breakpoints which have
5367 since been deleted, such as temporary breakpoints.
5368 infcmd.c (program_info): ditto.
5370 * core.c (core_file_command): Display the frame where the core
5375 * remote-vx.c (target_command): Merge in target command from
5376 targ-vx.c. A few other cleanups.
5378 * TODO, Projects: Lots more stuff to do...
5380 Fri Nov 23 18:15:38 1990 John Gilmore (gnu at cygint)
5382 Massive changes to wall off the remote-debugging interface
5383 behind a function vector. The port to handle VxWorks targets
5384 is also part of this.
5386 All files: Replace references to renamed functions,
5387 remove references to remote_debugging, remove references to
5388 have_include_file, have_core_file in favor of target_has_stack,
5389 target_has_memory, etc.
5391 * Modularize the breakpoint interface.
5392 breakpoint.h (BREAKPOINT_MAX): New define sets max length of
5393 a breakpoint instruction.
5394 breakpoint.c: struct breakpoint's shadow_contents now sized as
5396 (insert_breakpoints): Vector to target to install breakpoints.
5397 (remove_breakpoints): Vector to target here too.
5398 Remove REMOTE_SA_SPARC kludges and other remote_debugging.
5399 sparc-tdep.c (single_step): Use new breakpoint interface for
5400 the single-step breakpoints.
5401 mem-break.c (memory_insert_breakpoint, memory_remove_breakpoint):
5402 New file, contains routines to insert and remove breakpoints by
5403 reading out the old contents and later replacing them. This is
5404 how ptrace breakpoints work, and many remote systems as well.
5406 * tm-vxworks68.h: New config file, overrides a few things for
5407 Wind River's preferences.
5409 * target.h: New file, for transfer vector used to talk to the
5410 inferior (child, attached, core, exec, remote, etc). All accesses
5411 to the thing being debugged should come through these vectors.
5412 target.c: New file, routines to handle transfer vector.
5413 (various files): Add transfer vectors XXX_ops for the various
5414 targets and pseudo-targets (core files, etc) we support.
5416 * breakpoint.c (bpstat_stop_status): Further explorations of
5417 watchpoints and why things don't work all the time.
5418 (bpstat_alloc): New fn to allocate a bpstat and chain it.
5420 * config.gdb: Only add "source ${srcdir}/.gdbinit" to
5421 the local gdbinit if it doesn't already have it.
5423 * core.c (core_ops): add and install.
5424 Allow core debugging without exec file.
5426 * dbxread.c (free_and_init_header_files): Merge two fns.
5427 (end_symtab): Free named symbol table when a new version comes in.
5428 (read_dbx_symtab): Relocate all kinds of symbols with base
5429 address. First step toward handling different text, data, bss
5431 (add_file_addr_command): Renamed add_file_command.
5432 (add_file_command): Vector to remote handler.
5433 Add "load" as an alias for "add-file" command.
5435 * defs.h: Allow "volatile" to be used in non-ANSI; use it for
5436 non-returning functions.
5438 * exec.c: Add exec_ops, and push it as a target when an exec
5441 * infcmd.c (run_command): Pass executable file name and arg list
5442 separately when starting an inferior. Permit "run" when no exec
5443 file is specified, for VxWorks.
5444 (detach_command): Move to child_detach in inftarg.c.
5446 * inftarg.c: New file. Unix-child-specific routines, and the
5447 child_ops structure.
5449 * inferior.h (registers): Export "registers" as the way for
5450 target dependent register handlers to find gdb's local copy of
5451 the registers. Rename "stop_after_attach" to "stop_soon_quietly"
5452 since it is now used by places that want wait_for_inferior to
5453 handle the grunge but want to see every trap from the inferior.
5455 * inflow.c (create_inferior): Pull out, and merge into infrun.c.
5456 Eliminate remote_debugging hooks in terminal handling.
5458 * infrun.c: Replace start_inferior with child_create_inferior.
5459 Move all the hair of Unix shells and ptrace idiosyncracies into
5460 child_create_inferior, so remote handlers don't have to deal.
5461 Remove running_in_shell. Rename stop_after_attach to
5462 stop_soon_quietly, and use it in a few other places where we want
5463 to just call wait_for_inferior and get control back on the first
5464 trap. trap_expected now never takes a value > 1.
5465 (init_wait_for_inferior): Initialize static vars when a new
5468 main.c (gdbinit): Add new hook for .gdbinit file name, let
5469 it be overridden by config files as GDBINIT_FILENAME.
5470 (DEFAULT_PROMPT): Add new hook for overriding (gdb) prompt.
5471 Both of these are used for VxWorks gdb.
5473 mcheck.c: rename include file "gmalloc.c" to avoid problems
5474 with system include file "malloc.c".
5476 param-no-tm.h: New include file, same as param.h but does not
5477 include the default "tm.h" file. This is used in files where
5478 the target is known, e.g. remote-eb.c or sparc-xdep.c.
5480 param.h: Now just a shell that includes tm.h and param-no-tm.h.
5482 remote-vx.c: New file, VxWorks remote debugging support. Uses
5483 RPC routines that are shared with the target system, in directory
5486 remote.c: Vectorize remote interface.
5488 source.c: Globalize source_path, and make an alias "l" for "list"
5489 since we now have the "load" command.
5491 sparc-xdep.c: Use new param-no-tm.h.
5493 symmisc.c (free_named_symtab): Add new function from Wind River.
5494 However, ifdef it out for now while we think about what it should
5497 tm-sun3.h, xm-sparc.h, xm-sun3.h, xm-symmetry.h: Move
5499 the xm- file, and change its name to CHILD_PREPARE_TO_STORE, since
5500 non-Unix-children handle this with their own code in the target
5503 Makefile.dist: Roll version to 3.92.3. Add vx-share stuff to
5504 source and target lists. Add vx-share to default list of include
5505 directories. Add new files to src and target lists: mem-break,
5506 target, inftarg, remote-eb, remote-vx, targ-vx. Be sure the
5507 ${srcdir} versions of munch and createtags are used.
5509 * valops.c (find_function_addr): Split out of call_function.
5510 (call_function_by_hand): Rename call_function; this function
5511 calls functions in the target by laboriously patching the target
5512 word-by-word with the right stack, args, regs, etc.
5515 Mon Nov 5 17:29:10 1990 John Gilmore (gnu at cygint)
5517 Handle AMD 29000 a bit better.
5519 * remote-eb.c (readchar): Mask received char log to make it readable.
5520 (remote_start): Pass arguments down to executing program.
5521 Make startaddr unsigned.
5522 infrun.c (start_inferior): Accept args, pass them to
5524 infcmd.c (run_command): Pass args down to start_inferior.
5526 * tconfig/am29k-aout, tconfig/am29k-coff: New files specifying
5527 the target object file format.
5528 tm-29k.h: Pay heed to COFF_ENCAPSULATE.
5530 * am29k-pinsn.c (print_insn): Print 0x on hex numbers in disassembly.
5531 am29k-tdep.c (examine_prologue): Better checking of function prefixes.
5533 Sun Oct 7 18:20:45 1990 John Gilmore (gnu at cygint)
5535 * Makefile.dist (VERSION): Roll version to 3.91.9 and freeze.
5536 * TODO: We did a few things, we have more to do though.

5539 * inflow.c (inferior_died): Clear deferred stores.
5541 * Debug problems with dummy frames and calls to the inferior.
5542 * tm-sparc.h (PUSH_DUMMY_FRAME, POP_FRAME): Move to sparc-tdep.c.
5543 * sparc-tdep.c (do_restore_insn): Simplify.
5544 (sparc_frame_find_saved_regs): Simplify and fix what we find.
5545 (sparc_push_dummy_frame): Simplify and fix what we push.
5546 (sparc_pop_frame): Slightly more hair here, deciding whether
5547 we are restoring a saved PC or returning to a return address in %i7.
5548 * sparc-xdep.c (read_inferior_registers): Debug if valid reg is read.
5550 * utils.c (xmalloc, xrealloc): Return type depends on __STDC__.
5551 * symtab.h (xmalloc): ditto, for obstack_chunk_alloc.
5552 * obstack.h (chunkfun): ditto.
5553 * defs.h (xmalloc, xrealloc): ditto
5555 * utils.c (quit): Grab the terminal from the child if necessary.
5557 * inflow.c (term_status_command): Rename to term_info, change
5560 * sparc-pinsn.c (print_insn): Disassembly prefers real instructions.
5561 (is_delayed_branch): Speed up.
5562 * sparc-opcode.h: Add ALIAS bit to aliases. Fix up opcode tables.
5563 Still missing some float ops, and needs testing.
5565 * Support for input and output radixes other than base 10
5566 * defs.h (input_radix, output_radix): Declare.
5567 * expread.y (yyparse, parse_number): Handle changes of input
5568 radix, and ambiguous names-or-numbers in radixes >10.
5569 * printcmd.c (print_scalar_formatted): Print formatted hex
5570 numbers in varying column widths.
5571 * valprint.c (val_print): Use output_format to print scalar ints.
5572 (set_input_radix, set_output_radix, set_radix): Create.
5573 (set_output_radix): Set output_format from output_radix.
5574 (_initialize_valprint): add `set radix' but leave the others off.
5576 * main.c (execute_command): Let stupid questions be turned off.
5577 (_initialize_main): Handle "set stupidity", etc.
5579 * main.c, inflow.c, inferior.h, frame.h, command.c, defs.h,
5580 sparc-pinsn.c, sparc-xdep.c, value.h, valops.c, values.c: Lint.
5582 Tue Oct 2 11:20:02 1990 John Gilmore (gnu at cygint)
5584 * TODO, Makefile.dist, ChangeLog: Freeze for 3.91.8 release.
5585 bfd stuff is still screwed up, but with some manual work, it
5588 * breakpoint.c (bpstat_do_actions): Start over if a command
5589 proceeds the inferior, since the inferior will have stopped and
5590 will need to have its new stop-actions taken care of.
5592 * dbxread.c (read_struct_type): Expression gives Sun3 4.0.3
5593 compiler fits, simplify it.
5595 * gdb.texinfo (directory command): Doc new dir command.
5596 source.c (directory_command): "dir" now puts things on the front
5597 of the path, moves dups up front, and handles multiple names
5598 on the command line, inserting each one in order. It also
5599 blows away cached line and full_filename info.
5601 * stack.c (backtrace_command): Skip "more stack frames follow"
5604 * Change #ifndef HAVE_VPRINTF to #define MISSING_VPRINTF in
5605 xm-convex.h, xm-hp300bsd.h, xm-isi.h, xm-merlin.h, xm-news.h,
5606 xm-np1.h, xm-pn.h, xm-pyr.h, xm-symmetry.h, xm-umax.h, xm-vax.h.
5607 The only odd one was Gould NP1, which had defined vprintf to
5610 * Merge Ted Goldstein <tedg@Eng.sun.com>'s changes for epoch.
5611 printcmd.c (print_command_1): Pass 'inspect' flag down as a global
5612 variable, inspect_it.
5613 valprint.c (print_string, val_print): Use the global inspect_it
5614 to indicate whether to print in Epoch style or normal style.
5616 Mon Oct 1 23:55:26 1990 John Gilmore (gnu at cygint)
5618 * printcmd.c (call_command): add an alias for the "print" command
5619 which runs expressions and doesn't print the result if void.
5620 (print_command_1): implement it.
5622 * command.c: Remove #if 0'd code. Initialize all the fields
5623 in add_cmd (). Rename do_nothing_command to
5624 not_just_help_class_command, and make it externally visible.
5625 command.h: add user_commands to struct.
5626 * main.c (define_command): Don't overload c->function with a char
5627 string as well as a function pointer.
5629 * eval.c (evaluate_subexp): Reinstall tiemann changes to
5630 calling convention of value_struct_elt () that got dropped in
5633 * tm-sparc.h (FRAME_FIND_SAVED_REGS): move to sparc-xdep.c.
5634 sparc-tdep.c (sparc_frame_find_saved_regs): ditto.
5636 * tm-sparc.h (POP_FRAME): replace some constants with defines.
5638 * sparc-xdep.c (store_inferior_registers): defer stores to regs
5639 until a good time (e.g. when we are about to run the child),
5640 saving ptrace calls.
5641 * infrun.c (proceed): handle DO_DEFERRED_STORES.
5642 * tm-sparc.h: define DO_DEFERRED_STORES.
5644 * sparc-xdep.c (store_inferior_registers): when storing float
5645 registers, don't store stack regs too. When storing the SP,
5646 however, DO store the stack regs too. This fixes a bug in which
5647 the dummy frame is not recognized when a call_function finishes,
5648 because its frame pointer (in the stack regs) was never
5650 (read_inferior_registers): Mark WIM and TBR and FPS and CPS valid
5651 even though we don't know how to read them from an inferior.
5652 valops.c (call_function): Comment about storing SP.
5654 * infrun.c (save_inferior_status): Save away the original bpstat
5655 chain so it can be restored later. Install the copied version for
5656 use by whoever saved the status. It will be blow away by
5657 restore_inferior_status, and the original chain restored. This is
5658 important for people who have pointers into the original.
5660 * breakpoint.c, command.h, copying.awk, dbxread.c, defs.h,
5661 findvar.c, frame.h, obstack.h, obstack.c, inflow.c, value.h,
5662 main.c, printcmd.c, sparc-tdep.c, symtab.c, valprint.c: lint
5665 Fri Sep 28 20:32:46 1990 John Gilmore (gnu at cygnus.com)
5667 * Makefile.dist: Roll version to 3.91.8. Add bfd.h and bfdconfig.h
5668 temporarily to the makefile. Add am29k-opcode.h and WHATS.NEW.
5669 Add stuff.c and kdb-start.c to the OTHERS list for tar files.
5671 Fri Sep 28 19:12:12 1990 John Gilmore (gnu at cygint)
5673 * Merge Mike Tiemann's multiple inheritance changes from Sun.
5674 Store the baseclasses in a type struct starting from array element
5675 0 rather than from the unusual array element 1.
5677 dbxread.c: the above.
5678 (virtual_context): Add
5679 Read new debug information about which virtual function table
5680 a virtual function is from, and store it in fn_field.fcontext.
5682 symtab.h: Add fcontextt. Fix baseclass indices. Typo in
5683 TYPE_FN_FIELD_STATIC_P.
5685 symtab.c: the above.
5686 valops.c: the above. Handle pointer casts of object *'s.
5687 (search_struct_method): Add.
5688 (value_struct_elt): First arg is now a pointer to a value, and is
5691 valprint.c: the above.
5692 values.c (value_virtual_fn_field): Add type arg. Handle
5693 offsetting to the proper object when calling virtual fns.
5695 (baseclass_addr): Add valuep arg.
5697 * README: Document the current state of BFD config (missing).
5698 * TODO, ChangeLog, Makefile.dist: Roll version.
5699 * WHATS.NEW: Add summary of changes since 3.5.
5701 Thu Sep 27 16:23:12 1990 John Gilmore (gnu at cygint)
5703 * dbxread.c (read_struct_type): Clear bit vectors whenever
5705 symtab.c (B_CLRALL): define.
5707 * tm-sparc.h (STORE_RETURN_VALUE): Avoid clobbering types by
5708 using == rather than =. Huh... This fixes the dreaded problem
5709 wherein builtin_type_int becomes TYPE_CODE_FLT.
5711 * core.c (info_files): Show the inferior pid.
5713 * config.gdb: Avoid putting "dir" command into .gdbinit. GDB
5714 already knows how to look in the source directory.
5716 * Remove psymtab hair from many places. Remove duplicated code
5717 for searching symbol tables. Hide psymtabs from most places.
5718 Make it fast to get from a psymtab to its symtab.
5720 blockframe.c (blockvector_for_pc): Remove psymtab hair.
5721 coffread.c (psymtab_to_symtab): Rename to psymtab_to_symtab2.
5722 mipsread.c (psymtab_to_symtab): Rename to psymtab_to_symtab2.
5723 dbxread.c: export psymtab_to_symtab, make it work if called N times.
5724 (psymtab_to_symtab): Rename to psymtab_to_symtab2. Initialize
5725 new symtab completely. New psymtabs get symtab pointer
5726 initialized to zero. Remove MI warning printf.
5727 symtab.h: Comments. Add psymtab to symtab pointer.
5728 (PSYMTAB_TO_SYMTAB): New macro.
5729 symtab.c: use PSYMTAB_TO_SYMTAB. Add psymtab_to_symtab and export it.
5730 source.c: use PSYMTAB_TO_SYMTAB. Remove symtab version and
5732 stack.c (backtrace_command): Avoid pre-pass to read symbols, if
5734 (print_frame_info): Avoid special-casing symbols that have not yet
5737 * source.c (open_source_file): Quick path if we have already
5738 located the source file by its full name.
5740 * symtab.c (lookup_symbol): Use find_pc_symtab rather than
5741 find_pc_psymtab. When a name is found in the misc function
5742 vector, search the symbol table for its mangled name, not the
5743 name that the user typed.
5745 * bfd.h: Fix missing comment terminators, make #endifs match.
5747 * valarith.c (value_less): Handle unsigned int comparisons.
5748 Add FIXME about pointer compares, which assume host and target
5749 pointers are the same.
5751 * command.c (do_nothing_command): lint
5752 dbxread.c: lint. Remove sort_syms. Document C++ visibility info,
5753 fix comments on debug symbol format for visibility. Actually set
5754 visibility of symbols.
5755 main.c (echo_command): lint; use <readline/history.h>.
5756 tm-sparc.h (FRAME_FIND_SAVED_REGS): lint
5757 obstack.h (_obstack_blank): Rearrange pointer math to avoid
5758 pointing past end of allocated memory; saber complains.
5759 obstack.h: Declare the external functions that we use.
5760 valarith.h: use <string.h>
5761 solib.c (solib_add): lint.
5763 Fri Sep 21 17:05:19 1990 John Gilmore (gnu at cygint)
5765 * main.c (initialize_main): Default info_verbose to off, now that
5766 symbol reading is fast.
5767 (quit_command): Avoid clobbering exec_bfd while quitting.
5769 * Initial BFD (binary file diddling library) merger:
5770 coffread.c: Change AOUTHDR to struct exe_hdr.
5772 core.c: initialize initialized data at compile time.
5773 (core_file_command): Move from coredep.c, convert to bfd.
5774 (xfer_core_file): Convert to bfd.
5775 exec.c (exec_file_command): use bfd routines.
5777 mips-tdep.c: Remove exec_file_command and friends.
5780 * coredep.c: (fetch_core_registers) Convert core_file_command to
5781 fetch_core_registers.
5782 mips-xdep.c, sparc-xdep.c, sun3-xdep.c: ditto.
5784 * utils.c: (error): Bogus crap, FIXME, to print bfd errors.
5785 (my_bfd_read): More bogosity, which I don't think we call.
5786 (program_name): Remove this atrocity asap!
5788 Wed Sep 19 13:36:41 1990 John Gilmore (gnu at cygint)
5791 values.c: allocate_repeat_value was not clearing the
5792 optimized_out field.
5793 (value_static_field): minor stylistic fix (wrong macro was used).
5794 valops.c (value_struct_elt_for_address): didn't work for C++
5797 * signame.c (_initialize_signame): Initialize signal names once.
5799 * breakpoint.h, command.c, copying.awk, defs.h, environ.c,
5800 exec.c, frame.h, infcmd.c, inferior.h, main.c, munch, sun3-xdep.c,
5801 symtab.h, tm-29k.h, valprint.c, value.h, values.c: Lint.
5803 * remote-eb.c: Support user-settable baud rates on the serial port.
5805 * tm-sun3.h (PREPARE_TO_STORE): fix typo.
5807 Fri Sep 14 13:28:29 1990 John Gilmore (gnu at cygint)
5809 * tconfig/sun3os4: Remove warning about native assembler,
5810 since it also occurs in the xconfig file.
5812 * findvar.c (registers): Allocate some slop after `registers'
5813 to prevent stray accesses from trashing the next variable.
5815 * tm-68k.h (REGISTER_BYTES): Allocate the right number of bytes
5816 on the sun-3, by changing the #ifdef from `sun3' (which is not
5817 defined by cc) to `sun'. Symptom was trashed builtin_type_XXX
5818 vars, which happened to follow `registers' in the executable.
5820 * readline/history.c (history_search): Heed gcc-2's advice
5821 and parenthesize && inside ||).
5823 * am29k-opcode.h, am29k-pinsn.c, am29k-tdep.c, remote-eb.c,
5824 tm-29k.c: Insert FSF copyright headers.
5826 * remote-eb.c: Better comments.
5828 * Makefile.dist: Update to 3.91.6.
5829 * TODO: note PREPARE_TO_STORE problem.
5831 Thu Sep 13 09:52:33 1990 Jim Kingdon (kingdon at cygint)
5833 * stack.c (frame_info): Only use FRAME_FIND_SAVED_REGS if defined.
5835 * remote.c: Wrap the whole file in #if !defined (SPECIAL_REMOTE).
5837 * infrun.c (wait_for_inferior, at end): Don't set up
5838 prev_* if the inferior no longer exists.
5840 * inferior.h (CALL_DUMMY_LOCATION): New macro, to replace
5841 CANNOT_EXECUTE_STACK.
5842 valops.c (call_function): Use it.
5844 * tm-convex.h: Add CALL_DUMMY_LENGTH for use by PC_IN_CALL_DUMMY.
5846 * inferior.h (PC_IN_CALL_DUMMY): New macro.
5847 infrun.c (wait_for_inferior, 2 places): Use it.
5849 * values.c (value_being_returned): Only use
5850 EXTRACT_STRUCT_VALUE_ADDRESS if defined.
5852 * Move PREPARE_TO_STORE from xm-sun3.h to tm-sun3.h to do the
5853 right thing for remote-eb.c.
5855 * sun3-xdep.c: Remove extraneous call to remote_store_registers.
5856 * sun386-xdep.c, hp300hpux-xdep.c, sparc-xdep.c: Ditto.
5858 * blockframe.c: Put get_frame_saved_regs inside #if !defined
5859 (FRAME_FIND_SAVED_REGS).
5861 * findvar.c ({fetch,store}_registers): Check for
5862 REMOTE_{FETCH_STORE}_REGISTER macro.
5864 * findvar.c (get_saved_register): Add argument lval and
5865 change meaning of argument addr.
5866 findvar.c: Change calls to get_saved_register to reflect
5867 new calling convention.
5868 valops.c (value_assign): Use get_saved_register instead of
5869 find_saved_register.
5871 Sun Sep 2 12:40:20 1990 Jim Kingdon (kingdon at cygint.cygnus.com)
5873 * coffread.c (read_one_sym): Make temp_aux an AUXENT, not
5874 an (uninitialized) pointer to one. Use "&" when passing it
5877 Fri Aug 31 22:57:54 1990 Jim Kingdon (kingdon at cygint.cygnus.com)
5879 * coffread.c (getfilename): Use DGUX x_offset and x_name if
5882 * coffread.c (symbol_file_command): Put semicolon after
5884 Put safe_to_init_tdesc_context in #if defined (TDESC).
5885 Put #ifdef TDESCs in 1st column for non-ANSI cpp's.
5886 coffread.c: #include <sys/stat.h>.
5887 (read_coff_symtab): Typo: in_source_files -> in_source_file.
5888 Add missing ')' in check for "lc%" and friends. Remove
5890 Declare read_one_sym() at top of file.
5891 (read_file_hdr): Put in extra #ifdefs so MC68MAGIC and
5892 MC68WRMAGIC can have the same value without causing a duplicate
5895 Thu Sep 13 15:55:36 1990 John Gilmore (gnu at cygint)
5897 * Allow a Makefile to be built without building the
5898 tm and xm file links that screw up builds in subdirectories.
5899 This is done with `config.gdb none', then you can do things
5900 like `make gdb.tar.Z'.
5901 * tconfig/none: Config file for no target system
5902 * xconfig/none: Config file for no host system
5903 * config.gdb: If no TM or XM files are called out by the
5904 host or target file, don't make links for them.
5906 * cplus-dem.c: Add documentation.
5908 * dbxread.c (read_ofile_symtab): Turn a fatal error into a
5909 simple error, so the user's gdb doesn't crash due to some object
5910 file problem (e.g. somebody is rebuilding the file out from under
5913 * printcmd.c (print_address_symbolic): demangle the symbol.
5915 * Makefile.dist (OTHERS): Remove tdesc-lib because it has
5916 Motorola copyrights in it. Make "make gdb.tar.Z" work.
5917 (alldeps.mak): sort and uniq all results from this; duplicates
5918 hose gdb.tar.Z link building. Remove RCS files from
5919 tconfig and xconfig. Add config files for sun386. Add
5920 a few odd files to OTHERS and HFILES.
5922 Mon Sep 10 21:20:24 1990 John Gilmore (gnu at cygint)
5924 * Makefile.dist: Pull solib.c to tconfig/sun?os4.
5925 Roll version number to 3.91.5. Make lint work in bindir.
5927 * README: Document cross-debugging and new file structure.
5929 * blockframe.c: Lint. Include "value.h" to declare read_register.
5930 (find_pc_partial_function): remove duplicate line.
5932 * command.h: Lint. Declare error_no_arg and dont_repeat.
5934 * tm-news.h: Remove inadvertently duplicated stuff.
5936 * mipsread.c: Remove cache_pc_function stuff, now done cleanly.
5937 Clean up usage of misc_function_type. Declare some CORE_ADDRs.
5939 * config.gdb: Allow `config.gdb host target' form. Clean
5940 up previous change that printed bogus messages when you just said
5943 * core.c: #include "command.h" for lint.
5946 * main.c: Remove some casts of enums. Lint.
5953 * printcmd.c (initialize_printcmd): Fix thinko in inspect cmd.
5955 * sparc-tdep.c (isannulled): Take instruction as parameter, don't
5956 read it from memory. This will allow us to save ptrace calls
5957 eventually. Changed caller single_step too.
5959 * sparc-xdep.c (fetch_inferior_registers): Avoid reading regs
5960 that we aren't going to use, saving many ptrace calls, especially
5961 when watchpointing or single stepping. Use some #define's for
5963 (store_inferior_registers): Ditto.
5964 (core_file_command): Use some #define's for constants.
5966 * tm-sparc.h: Add #define's for some register numbers, so we
5967 can eliminate the use of random constants in sparc-xdep.c.
5969 * stack.c (frame_command, print_frame_info, up_command,
5970 down_command) Remove frame_changed, since it
5971 causes a bug and doesn't seem to do anything useful. In some
5972 places it was used as a flag, in others as a stack level (?).
5974 * utils.c: Use MISSING_VPRINTF rather than HAVE_VPRINTF, so the
5975 default is to use the portable (vprintf) version rather than the
5977 * xm-news.h (MISSING_VPRINTF): Add.
5979 * valprint.c (val_print): Demangle fancy vtbl printouts. Lint.
5981 Sat Sep 8 00:24:12 1990 John Gilmore (gnu at cygint)
5983 * Remove stuff that forces -Bstatic linking of gdb, and warnings
5984 about linking debugged programs -Bstatic in the sun?os4 config
5985 files in tconfig and xconfig subdirectories.
5987 * main.c (main): Remove unreached exit(0) now that we exit
5990 * Create TODO file for online bug list. There are too many
5991 "little" bugs to keep track of on paper.
5993 * Change Projects file to refer to bug-gdb@cygnus.com
5994 rather than kingdon@ai.
5996 Fri Sep 7 23:35:15 1990 John Gilmore (gnu at cygint)
5998 * Makefile.dist (VERSION): 3.91.4 now.
6000 * symtab.c (init_misc_bunches): Rename from init_misc_functions.
6001 (condense_misc_bunches): Add sanity check that misc_count is
6002 the same as the number of symbols in the bunch.
6004 * coffread.c: rename init_misc_bunches. Pass an argument
6005 to condense_misc_bunches (a zero).
6007 * dbxread.c (partial_symbol_file_read): Call init_misc_bunches
6008 every time we are called; don't rely on our caller to do it.
6009 (add_file): Remove call to init_misc_bunches.
6011 * mipsread.c: Only warn, don't error, if unknown symbol types.
6012 This keeps an old gdb from falling on its face if it sees newly
6013 extended symbol info. Rename init_misc_bunches.
6015 Fri Sep 7 22:58:15 1990 John Gilmore (gnu at cygint)
6017 * Merge in changes from Per Bothner for DECstations and other
6018 MIPS stuff. The rest is Bothner speaking:
6020 The next message is a merger of Alessando Forin's mips port with
6021 mine. I've tried to use my good if biased judgment to get
6022 the best of both. It *does* need testing.
6024 Some of the changes are general, *not* mips-specific.
6027 Didn't believe in little-endian bit order.
6028 There are still inconsistencies about whether flags
6029 like BITS_BIG_ENDIAN are integer (#if ...) or
6030 boolean (#ifdef ...). I tried to paper over them.
6032 dbxread.c,coffread.c,mipsread.c,symtab.c,symtab.h:
6033 Moved some misc_function code that was common to
6034 {dbx,coff,mips}read.c to symtab.c.
6035 In the process, I think I cleaned things up a bit.
6036 At the same time, moved obsavestring and obconcat to symtab.c.
6039 Removed obsolete condense_addl_misc_bunches (use
6040 condense_misc_bunches(1) instead).
6043 Needed to include <sys/dir>, at least on DECstations.
6045 valops.c, mips-tdep.c, tm-mips.h:
6046 Added PUSH_ARGUMENTS macro to support funny argument-pushing
6047 conventions (when STACK_ALIGN is insufficient).
6048 Needed on mips, where doubles need 8-byte alignment,
6049 but ints only need 4.
6052 Removed cruft that was not being used.
6053 Merged in many fixes (most from Frank Yellin, fy@lucid.com).
6056 Print $ before register-names (I think that makes things a little
6058 Never print two instructions, even if one delays.
6059 Removed hex-disassemble set_cmd. (This is not mips-specific,
6060 so I think the argument is whether it is generally worthwhile or not.
6061 I'm inclined to think not, given how easy it is to
6062 convert between radixes in gdb.)
6065 This is basically Alessando's code.
6066 It doesn't use obstacks; I changed it to use obstacks
6067 in a few minor places where using malloc causes a
6068 memory leak. (Probably, more places could/should be changed.)
6069 I added record_misc_function where it was missing.
6070 In symbol_file_command and add_file_command, I tried
6071 to make the code consistent with more recent versions.
6072 Minor sylistic changes in parse_procedure.
6073 Make a .gdbinfo. psuedo-symbol point back to the real
6074 procedure symbol (using the isym field).
6077 This is basically from my port, but with a lot of details
6078 and a number of routines merged in from Alessando's version.
6079 I basically used my code "raw" backtrace (use heuristics
6080 from the actual code, rather than symbol table info) - though
6081 the idea is Alessandro's. I feel my code is a little cleaner
6082 here, particularly in being a little more flexible, such as being
6083 able to handle gcc-produced code (which it now can).
6084 It also doesn't do frame caching (which is not useful
6085 more recent gdb versions).
6086 I also used my code for push_/pop_dummy, more or less.
6087 I tried to incorporate AF's code for testing sigtramp
6088 while backtracing; I probably got it wrong.
6089 Added mips_print_register, which tries to scrunch as much
6090 information as possible on a screen...
6091 Removed the skip-prologue set_cmd. As with hex-disassemble (see
6092 under mips-pinsn.c), I don't see anything mips-specific here,
6093 and I don't see it being all that useful anyway.
6096 Added a $fp psuedo-reg distinct from $fp (nice for gcc).
6097 Use more register names (rather than hard-cases numbers).
6099 Thu Sep 6 18:33:15 1990 John Gilmore (gnu at cygint)
6101 * Hack up 3.90.11 changes:
6103 * Makefile.dist (depend): parameterize $(GCC).
6104 Add solib.c and solib.o.
6105 (readline): Fix vpath for both absolute or relative SRCDIR.
6107 * blockframe.c: Fix from Schaefer@asc.slb.com for shared libs.
6108 Also, let the part I didn't understand at least compile so
6109 I can test the rest. FIXME.
6111 * dbxread.c: Fix thinko using strcmp.
6112 (init_psymbol_list): declare static.
6113 (partial_symbol_file_open): Comment cleanups better, avoid
6114 cleaning up the string table since the caller will do that.
6115 Move the stat for mod time into symbol_file_command, temporarily.
6116 (There should be a mod time for each symbol file, eventually,
6117 to control its rereading. FIXME.)
6119 * infptrace.c (PT_WRITE_D): use same value as PT_WRITE_I for
6120 SunOS, which gives error for shared libs otherwise. (From
6121 Schaefer, probably FIXME needs work for portability.)
6123 * solib.c: Move #include "param.h" to work.
6124 Lowercase all the Uppercase Letters In the Messages.
6125 (find_solib): Clean up inferior_so_name for debug printouts.
6126 Allow no argument, to mean all shared libraries.
6128 * symmisc.c: include param.h to get CLEAR_SOLIB.
6130 Wed Sep 5 18:00:08 1990 John Gilmore (gnu at cygint)
6132 * Merge in Kingdon's changes from FSF: the diffs from 3.90.9
6133 to 3.90.11. ChangeLog entries below are from this.
6135 Wed Jun 13 09:17:39 1990 Jim Kingdon (kingdon at mole.ai.mit.edu)
6139 * Makefile.dist (HFILES): Add tm-sunos.h.
6141 Tue Jun 12 16:15:26 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
6145 * Makefile.dist (gdb.tar.Z): Change linking of config so it works.
6147 Thu Jun 7 16:22:27 EDT 1990 Jay Fenlason (hack@ai.mit.edu)
6149 * sparc-opcode.h Added single-operand version of rett.
6151 Mon Jun 4 18:12:31 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
6153 * m-sparc.h (REG_STRUCT_HAS_ADDR, STRUCT_ARG_SYM_GARBAGE):
6154 Put parens around gcc_p in expansion.
6156 Thu May 24 15:44:51 1990 Jim Kingdon (kingdon at mole.ai.mit.edu)
6158 * utils.c (lines_to_list): Return 10 if lines_per_page == 0.
6160 Wed May 23 16:36:04 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
6162 * Changes for Sun shared libraries:
6163 blockframe.c (find_pc_partial_function): If a non-text symbol
6164 is found, set *address = pc - FUNCTION_START_OFFSET.
6165 breakpoint.c (insert_breakpoints) [DISABLE_UNSETTABLE_BREAK]:
6166 Disable breakpoints instead of giving an error.
6167 source.c (select_source_symtab): Initialize cs_pst.
6168 symmisc.c: Call CLEAR_SOLIB if defined.
6169 symtab.h: Make text{low,high} CORE_ADDR not int.
6170 (psymtab): New field addr.
6172 dbxread.c: Move DECLARE_FILE_HEADERS outside functions.
6173 (record_misc_function): Give correct type for N_DATA symbols.
6174 (condense_misc_bunches): do "misc_function_count = j" regardless
6176 Take code which is shared between symbol_file_command and
6177 add_file_command and put it into partial_symbol_file_{open,read}.
6178 Split add_file_command into add_file_command and add_file.
6179 Make psymtab_to_symtab read in the string table if the file
6181 Two new parameters to read_dbx_symtab and start_psymtab.
6182 tm-sunos.h: New file.
6184 Tue May 22 17:43:03 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
6186 * infcmd.c: Change cont_command to continue_command and "cont"
6189 Mon May 21 14:41:41 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
6191 * breakpoint.c (enable_breakpoint): Get value of watchpoint.
6193 * defs.h [sparc]: Use <alloca.h> regardless of __GNUC__.
6195 * values.c (USE_STRUCT_CONVENTION): Check for structures of
6196 size 1,2,4,8 rather than size < 8.
6198 * dbxread.c (dbx_lookup_type): Do f->length *= 2 as many times
6199 as necessary, not just once.
6201 * sparc-opcode.h: Add a bunch of new opcodes which Sun as supports.
6203 Thu May 17 15:04:09 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
6205 * {t,x}m-sun386.h, sun386-xdep.c, {x,t}config/sun386
6207 * tm-news.h: Add CALL_DUMMY_*.
6209 * tm-68k.h: Remove duplicate comment at FRAME_FIND_SAVED_REGS.
6211 * config.gdb: In list_host, list_target, use ${i}, not $i.
6213 Tue May 15 21:27:12 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
6215 * source.c (find_source_lines) [BROKEN_LARGE_ALLOCA]: Use xmalloc.
6217 * sparc-opcode.h: Change all store floating-point state register
6218 instructions to have the right match & lose fields.
6220 Sat May 5 12:39:18 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
6222 * Makefile.dist: Move -I${srcdir} to GLOBAL_CFLAGS and pass
6224 config.gdb: If srcdir != ., create readline directory and
6225 copy a makefile into it.
6227 * wait.h, infrun.c: Change WRETCODE to WEXITSTATUS for
6228 consistency with POSIX.
6230 * breakpoint.c (bpstat_stop_status): Disable watchpoint
6231 when we exit its exp_valid_block.
6233 Tue Sep 4 11:46:46 1990 John Gilmore (gnu at cygint)
6235 * Makefile.dist: Bump version to 3.91.3.
6237 * Clean up handling of breakpoint commands (somewhat).
6238 Prompted by Tiemann bug report "cont 10" doesn't work any more.
6240 inferior.h: Add breakpoint_proceeded to inferior status struct
6241 and globals; save it and restore it.
6242 (clear_breakpoint_commands): Cleanup, remove old #define.
6244 infrun.c (clear_proceed_status): Set breakpoint_proceeded.
6245 (save_inferior_status, restore_inferior_status): handle it also.
6246 (proceed): Remove earlier code that set breakpoint_proceeded.
6247 It is now set only in clear_proceed_status.
6248 (clear_proceed_status): Cleanup, use bpstat_clear rather
6249 than clear_breakpoint_commands. No callers need the stop_bpstat
6250 between clear_proceed_status and proceed.
6252 infcmd.c: Add breakpoint_proceeded definition and comment.
6253 (cont_command, jump_command, signal_command): Move call to
6254 clear_proceed_status right next to call to proceed.
6256 breakpoint.c (bpstat_do_actions): Avoid clobbering our
6257 caller's argument while running down the chain of breakpoints.
6258 Use new variable "breakpoint_proceeded" to determine when
6259 a command that it executes moves the inferior past the
6261 (bpstat_clear): Handle NULL argument.
6262 (bpstat_clear_actions): Avoid useless call to
6263 breakpoint_auto_delete.
6264 (delete_breakpoint): Clean up bpstat's that are pointing to
6265 the deleted breakpoint from the stop_bpstat chain.
6266 (breakpoint_auto_delete): Simplify.
6268 * Clean up handling of EOF, error on stdin, etc. This was
6269 prompted by a network problem that caused gdb to go into an
6270 infinite loop filling up its malloc'd memory.
6272 main.c (return_to_top_level): Cleanup: call bpstat_clear_actions,
6273 not clear_breakpoints_commands, which is now gone.
6274 (main): If command_loop returns (e.g. from EOF on stdin), do
6275 a quit_command (looping back to command_loop if quit_command
6276 doesn't really quit).
6277 (command_loop): check result from command_line_input and
6278 exit if it returns NULL, rather than passing the NULL to
6280 (gdb_readline): Free malloc'd result space before returning
6283 * utils.c (query): Handle C-d to mean "yes", just as if the
6284 input was not a terminal. Also avoid infinite loop if EOF
6285 occurs in mid-input-line before newline. This allows
6286 query to be used at EOF on stdin with reasonable results.
6288 * infrun.c (proceed): Set breakpoint_proceeded.
6290 * values.c (value_as_long): Avoid infinite recursion for enums.
6291 (_initialize_values): Fix typo in help msg (kingdon).
6293 * Makefile.dist (RL_LIB): Use RL_LIB_DEP for dependencies,
6294 RL_LIB for linking. This allows -lreadline for linking
6295 and nothing for dependencies, once readline is a real library.
6297 * config.gdb: Jim Kingdon: give useful error message if the
6298 host or target type is not recognized.
6300 * defs.h (alloca): SPARC <alloca.h> does not declare alloca,
6301 it just defines it. Dumb, but deal with it.
6303 * Jim Kingdon suggests:
6304 in xconfig/sun3os4, CFLAGS should be XM_CFLAGS.
6306 Wed Aug 29 18:03:27 1990 John Gilmore (gnu at cygint)
6308 * Makefile.dist (VERSION): Bump version # to 3.91.2.
6310 * Clean up Bothner's changes.
6312 * blockframe.c (clear_pc_function_cache): New function.
6313 * blockframe.c: remake cache_pc_function_* static.
6314 * dbxread.c (symbol_file_command): remove references to
6315 cache_pc_function_* variables.
6316 * dbxread.c (read_struct_type): Use VOFFSET_STATIC.
6317 * printcmd.c: Avoid kludging a global variable (addressprint)
6318 to avoid printing the address of a string twice. Instead,
6319 pass the format letter 's' down low enough that it can be seen
6320 to avoid this problem.
6321 (print_formatted): Pass format arg to value_print.
6322 (restore_addressprint): Remove function.
6323 (do_examine): Avoid hacking addressprint, cleanups and such.
6324 (print_frame_args): Add a comment to a Bothner change.
6325 * symtab.h: define VOFFSET_STATIC and use it instead of "-1".
6326 * symmisc.c (free_all_symtabs): Call clear_pc_function_cache
6327 to wipe out the values cached in blockframe.c.
6328 * symtab.c (find_method): Add comment saying how big you must
6329 allocate to be "big enough". Per being terse again.
6330 * valprint.c (val_print): Handle format letter "s" to print
6331 strings without addresses. Add comment to vtbl printing code
6332 which casts with wild abandon. Rearrange reference-printing
6334 @0xaddr: value (print w/addressprint)
6335 value (print w/~addressprint)
6336 @0xaddr (parameter lists w/addressprint)
6337 or nothing (parameter lists w/o addressprint)
6339 Tue Aug 28 10:47:18 1990 John Gilmore (gnu at cygint)
6341 * Merge more changes from Per Bothner:
6343 Gdb's handling of TYPE_CODE_REF was so counter-C++ (and otherwise
6344 annoying) that I tried to improve it. Here are my suggestions.
6346 These patches all attempt to handle TYPE_CODE_REF (as in C++) better.
6349 Do automatic de-reference when taking the address of a reference.
6351 Don't deref_ref when printing parameter lists.
6353 More attempts at treating refernences properly.
6355 In val_print, if deref_ref==0, don't print dangling " = ".
6357 Add COERCE_REF macro, which de-references an REF.
6359 * Merge changes from Per Bothner:
6361 * Fixed (Sony news)-specific configuration problems.
6362 * Fixed other problems with using vanilla pcc and libc (enum problems;
6363 assumption that vsprintf exists).
6364 * Some major speed-ups (finc_pc_partial_function now caches a match;
6365 parsing avoids duplicate symbol_lookup calls).
6366 * Changed handling of baseclasses (no longer use baseclasses field
6367 of struct type, use the first n_baseclasses fields instead).
6368 * Various minor changes/fixes, most C++-related.
6371 Cache the most previous match from find_pc_partial_function.
6372 (Save both low and high ends of matching function's pc range.)
6373 This speeds up the loop of infrun.c:wait_for_inferior quite
6374 a bit, and makes step/next commands much zippier.
6376 Added an enum->int cast (otherwise, some compilers barf).
6378 No longer set baseclass offset to 0, since multiple
6379 inheritance now mostly works.
6380 Added a number of casts, to shut up compiler warnings
6381 (after stabs where made enums, not ints).
6382 When discarding a symbol table (in symbol_file_command),
6383 must clear the cache introduced in blockframe.c.
6384 Don't convert $vtbl_ptr_type to vtbl any more.
6385 Get rid of TYPE_BASECLASEES and baseclass_vec (see also symtab.h).
6386 Mask off sign bit emitted by g++ for virtual table offset.
6387 Set voffset to -1 (not 1) for static member functions.
6389 Changed parsing/lexing of names to avoid doing symbol lookup twice
6390 (once when lexing to determine symbol class, once for real).
6391 Now only call symbol_lookup once. Fields of 'this' win especially big.
6393 Subpress printing addr twice in the case of 'x/s addr'.
6395 lookup_basetype_type is no longer used.
6396 Add find_methods as recursive helper function to decode_line_1.
6397 This allows multiple inheritance to work.
6398 Also, once one or more matches has been found, do not look in
6399 base-classes. (Baseclass methods would be overridden, anyway.)
6401 Removed baseclasses array in struct type.
6402 Instead of using baseclasses[i], use fields[i-1].
6403 Added virtual_field_bits[i] to indicate if the i'th baseclass is virtual.
6404 Changed sign convention of voffset (previous was inconsistent).
6406 Some macros (CALL_DUMMY and relatives) were missing. Put them back.
6408 Used to assume existence of vsprintf. Re-written to not need it
6409 if HAVE_VPRINTF is undefined.
6411 typecmp was too pessimistic. Made it less so.
6413 Don't print space after address.
6414 If vtable points to a misc symbol (with 0 offset), print it,
6415 since that indicates the actual class of the object.
6416 Changed ype_print_derivation_info to use new inheritance
6417 scheme (without baseclasses vector).
6419 In value_primitive_field, fixed some bugs left over from previous set of fixes.
6420 Also, changes needed because TYPE_BASECLASSES were removed.
6422 REGISTER_U_ADDR didn't work for PC. Rewrote to use an array.
6424 Tue Aug 21 20:08:54 1990 John Gilmore (gnu at cygint)
6427 If there is no path set, and the symbols don't indicate what directory
6428 a file was compiled in, look in the current directory. But either
6429 a path or a known compilation directory will prevent this.
6432 Three independent bug fixes:
6433 * Remove the #if 0 block that breaks some stuff.
6434 * SunOS 4.1 fixed the promoted-parameter-wrong-addr bug in Sun C;
6435 adapt gdb to either SunOS 4.0.* or 4.1.
6436 * MAX_OF_TYPE and MIN_OF_TYPE thinko. By tedg@sun, I think.
6439 Instantiate the class T when looking for methods in it. (Tiemann@sun)
6442 (type_print) Demangle the name being printed.
6443 (type_print_base) Handle botched demangling without coredump (tiemann).
6446 (check_stub_method): Document routine.
6447 (tiemann) fix bug for no-arg functions
6448 Avoid clobbering beyond end of malloc'd storage.
6449 Terminate the argument list properly.
6451 Sat Aug 18 01:29:59 1990 Per Bothner (bothner@cs.wisc.edu)
6453 * Changes merged by John Gilmore:
6456 In breakpoint_1, use new print_address_symbolic instead
6457 of find_pc_partial_function. (This forces use of assembler-level
6458 addresses, and avoids misleading non-mangled source-level names.)
6460 Generalize ansi argument such that -1 means skip arglist totally.
6461 Removed global variable print_ansi_qualifiers (which made
6462 code non-reentrant), in favor of extra explicit arguments
6463 to internal routines.
6465 Add new helper function print_address_symbolic.
6466 Use find_pc_misc_function instead of find_pc_partial_function
6467 (since we want assembler-level symbols here).
6469 Print unknown function as just "f (...)", not "f (...) (...)".
6470 Use new fputs_demangled explicitly.
6472 Fixed a typing violation (problem: value.h cannot be imported
6473 without renaming many variable in this file).
6474 lookup_symbol: If no matching misc_func, look for a C++-mangled name.
6475 decode_line_1: Moved forward some never-reached code.
6476 Made decode_line_2 skip function prologues correctly.
6478 fputs_filtered should not demangle by default.
6479 Add new fputs_demangled to demangle on demand..
6481 Change value_struct_elt to use value_primitive_field (using recursive
6482 utility function search_struct_field). This allows foo.bar to work
6483 for multiple inheritance (so far only for data fields).
6484 Change check_field in the same way (recursive helper function
6485 to support multiple inheritance).
6486 (Note: there are more of these problems that I haven't fixed.
6487 Any code that says TYPE_BASECLASS (t, 1) is probably wrong.)
6488 value_of_this: 'this' symbol name is now just "this", note "$this".
6490 Don't print static members.
6491 Avoid printing "members of <type>" if there are none.
6492 Simplified type_print_derivation_info by merging duplicate code.
6493 Remove useless blank lines in type_print_base (ptype command).
6495 Added declaration of new routine value_primitive_field.
6497 Added value_primitive_field which is generalized version of
6498 value_field that can handle multiple inheritance (non-zero offsets etc).
6499 Re-implemented value_field to call value_primitive_field.
6501 Fri Aug 17 23:33:44 1990 John Gilmore (gnu at cygint)
6503 * infcmd.c -- insert else to avoid 'delete env' coredump when you
6504 delete the whole environment. Karl Berry reported the bug.
6505 * source.c - fix openp to avoid //'s in filenames, which
6506 trigger an Emacs bug causing it to not be able to find files
6507 when running gdb in a window.
6508 * dbxread.c - zap the #if 0 that botches the add-file code.
6509 It seems to work a lot better without all the code commented out.
6511 Fri Jul 20 16:58:46 1990 John Gilmore (gnu at cygnus.com)
6513 * Merge Tiemann's and Ted Goldstein's changes, detailed below,
6516 Tue Jul 17 19:34:33 1990 Ted Goldstein (tedg at golem)
6518 * Makefile - added a ${CFLAGS} to a couple of entries,
6519 added remote-sa.sparc.c
6520 * added remote.sa-sparc.c, a modification of remote.c
6521 which conducts a dialog directly with the SparcStation prom.
6522 * breakpoint.c, infrun.c, sparcdep.c added
6523 remote_insert_breakpoint(), and remote_remove_breakpoint()
6524 to breakpoint.c instead of directly writing breakpoint instructions.
6525 * sparcdep.c on remote_debugging,there is no need
6526 to remove signle step breakpoint instructions.
6527 * main.c added "-epoch" flag and "int epoch_interface" to main.c
6529 * printcmd.c - epoch interface sends lisp expressions to open up
6530 epoch windows on inspection.
6531 * valprint.c - added arrayprint, and addressprint and made adding
6532 format controls easier
6533 * wait.h added a couple of undef's because we were getting
6534 complaints about WSTOPSIG and WTERMSIG begin redefined.

6562 should print ANSI qualifiers (such as `const' and `volatile').
6563 All callers changed to call with ANSI == 1, except from
6564 `check_method_stub', which uses old-style syntax.

6567 * symtab.h (TYPE_FN_FIELD_ARGS): Redefined.
6569 * values.c (check_stub_method): New function.

6604 * valprint.c (everywhere): TYPE_NAME (TYPE) no longer comes in the
6605 form "struct ..." for GNU C++. Don't flush any part of TYPE_NAME
6606 when printing the type.

6630 step_resume_break_address != NULL, even if another_trap.
6631 If trap_expected and we enter sigtramp, then set up a
6633 If trap_expected is set when we hit the step_resume_break,
