1 Tue Nov 19 07:53:55 1991 Fred Fish (fnf at cygnus.com)
3 * c-exp.y, m2-exp.y: Add defines for yymaxdepth, yy_yys, and
4 yy_yyv, so multiple parsers produced by SVR4 versions of yacc
5 can coexist in the same executable without collision.
7 * symtab.h: Add declaration for lookup_template_type() to kill
8 compiler warnings about conversions from int to pointer.
10 Mon Nov 18 17:45:18 1991 Fred Fish (fnf at cygnus.com)
12 * procfs.c: Move inclusion of defs.h to before param.h, as in
13 all the other source files that include both. This is required
14 to supply some typedefs that are used in files included by param.h.
16 * m68k-tdep.c (m68k_skip_prologue): Add generic m68k support for
17 skipping function prologues, ala the other cpu families (i386,
18 mips, m88k, etc). Add the ability to skip movm and fmovm
19 instructions in the prologues. Still needs support for profile
20 (-p compiled) prologue sequences (FIXME).
22 * tm-68k.h: Change SKIP_PROLOGUE macro to use the new generic
23 m68k prologue skipping function by default.
25 * tm-altos.h, tm-isi.h: Continue to use the old definition of
28 Mon Nov 18 15:12:45 1991 John Gilmore (gnu at cygnus.com)
30 * Makefile.in: Remove tdesc stuff, and extra blanks before colons.
31 * blockframe.c: Remove tdesc-related code. Default
33 * infrun.c: Remove tdesc-related code.
34 * m88k-tdep.c (frame_chain_combine, init_frame_pc): Remove copies
35 of defaultable things.
36 * tm-m88k.h: New file, common to all Moto 88k target configs.
37 Derived from tm-delta88.h.
38 * tm-delta88.h: Use it.
39 * xm-m88k.h: Common file for 88K hosts. Remove obsolete stuff.
40 * xm-delta88.h: Use it.
41 * tm-*.h: Remove FRAME_CHAIN_COMBINE macros, since all are
43 * coffread.c: Remove tdesc stuff.
44 * tconfig/delta88, tconfig/m88k: Remove tdesc stuff.
45 * xconfig/m88k: Rename tm-88k.h to tm-m88k.h.
47 Mon Nov 18 13:51:37 1991 Per Bothner (bothner at cygnus.com)
49 * source.c (open_source_file): If openp fails, try again
50 using just the base (non-directory) part of the filename.
51 This solves various annoying problems, such as when the
52 source was compiled with an absolute pathname - and the
53 source files have moved. Or if the source was compiled
54 using a relative pathname, it can be more convenient
55 to just specific the source directory to the dir command.
57 Mon Nov 18 00:04:41 1991 Fred Fish (fnf at cygnus.com)
59 * cplus-dem.c (munge_function_name): Add missing third arg to
60 instance of call to do_type().
62 * dwarfread.c: Changes to match new dwarf.h. Remove
63 AT_deriv_list, AT_loclist, AT_incomplete, AT_const_data,
66 Sun Nov 17 16:20:53 1991 Michael Tiemann (tiemann at rtl.cygnus.com)
68 * symtab.h (struct type): Moved C++-specific fields into new type
69 `struct cplus_struct_type'. Now takes 10% less memory. Many
71 * symtab.c (init_type): Don't set fields belonging to
72 TYPE_CPLUS_SPECIFIC unless TYPE is TYPE_CODE_STRUCT.
73 * buildsym.c (read_type): Allocate TYPE_CPLUS_SPECIFIC for
75 (read_struct_type): Ditto. Also, add comments about how we can
76 deduce TYPE_VPTR_FIELDNO from inheritance info and fieldname info.
77 * coffread.c (decode_base_type): Allocate TYPE_CPLUS_SPECIFIC for
79 (read_struct_type): Ditto.
80 * dwarfread.c (struct_type): Ditto.
82 * symtab.c (read_range_type): Don't set TYPE_MAIN_VARIANT.
83 (lookup_pointer_type): Don't use or set TYPE_MAIN_VARIANT.
84 (lookup_reference_type): Ditto.
86 * cplus-dem.c: Many changes made to handle decoding of

93 * mipsread.c (parse_partial_symbols): patch to keep DEC C
94 compiler from making gdb bomb out. Thanks to Ed Santiago!
96 Thu Nov 14 19:27:30 1991 Fred Fish (fnf at cygnus.com)
98 * symfile.c: Add function compact_misc_function_vector() to
99 remove duplicate misc function vector entries. See comments
100 in source for why this is necessary/desirable.
102 * dwarfread.c: Add misc function type parameter to internal
103 record_misc_function(). Remove calls to init_misc_bunches()
104 and condense_misc_bunches(), these are now done in elfread.c.
106 * elfread.c: Add support for reading bfd canonical symbol tables
107 and generating misc function vector entries for global and
108 absolute symbols. Do calls to init_misc_bunches() and
109 condense_misc_bunches() where they will enclose all calls to
110 record_misc_function(), including those in dwarfread.c.
112 Thu Nov 14 17:02:11 1991 Roland H. Pesch (pesch at cygnus.com)
114 * doc/Makefile.in: new targets gdb.me, gdb.ms, gdb.mm
115 (roffable documentation).
116 * doc/gdb.texinfo: embedded hints (as comments) for better
117 texi2roff conversion.
119 Thu Nov 14 13:18:25 1991 John Gilmore (gnu at cygnus.com)

133 Motorola 88000 port without tears, I mean without tdescs.
135 * m88k-tdep.c: Blow away all tdesc stuff.
136 Provide functions for all the frame-related macros in
137 tm-delta88.h. Adopt i960-style EXTRA_FRAME_INFO.
138 (examine_prologue, frame_find_saved_regs, skip_prologue): borrow
139 from i960-tdep.c and adapt to the function prologues on the 88k.
140 (read_next_frame_reg): Borrow from mips-tdep.c.
141 FIXME: frame_locals_address should go away.
143 * tm-delta88.h: Dump all the tdesc stuff.
144 Macros for all frame-related stuff call fns of same name.
145 Remove duplicated definitions. FP_REGNUM becomes same as
148 * xm-88k.h: Eliminate lots of library dependencies, now handled
149 in libiberty. Eliminate KDB nonsupport.
151 * doc/gdbint.texinfo: Add rudiments on frames. FIXME, add more.
154 * stack.c (frame_info): Mark frameless functions.
155 Print locals address (FIXME, remove if same).
156 * blockframe.c: Comment changes, FIXME after.
157 * coffread.c: Even without TDESC, need to zap "@" symbols.
158 Don't register for wierd format names; change the names in BFD.
160 * alloca.c, language.c, tdesc.c: Lint.
161 * tdesc.c, tdesc-lib: FIXME: remove these.
163 Tue Nov 12 19:30:22 1991 John Gilmore (gnu at cygnus.com)
165 * Makefile.in: Add tdesc library support. Fixups to lint,
168 Tue Nov 12 13:43:26 1991 Per Bothner (bothner at cygnus.com)
170 * symtab.c (decode_line_1): Remove spurious call to operator_chars.
172 Allow setting breakpoints on C++ destructors.
173 * valops.c (destructor_name_p): Don't check TYPE_HAS_DESTRUCTOR,
174 since it lies. Rely on callers to catch missing destructors.
175 * symtab.c (decode_line_1): For example (see above), here.
176 * buildsym.c, symtab.h: Remove TYPE_FLAGS_HAS{CON,DE}STRUCTOR
177 flags since they are no longer used.
179 Fixes to support C++ methods with functional parameters.
180 * c-exp.y (func_mod rule): Allow (and ignore) list of parameter
181 types in a function type.
182 * eval.c (parse_and_eval_type), value.h: New function,
183 parse_and_eval_type, is based on old code from check_stub_method.
184 But don't actually evaluate the cast, since that calls
185 value_cast(), whcih may fail. Just extract the type
186 from the parsed expression.
187 * values.c (check_stub_method): While looping through the
188 arguments, adjust depth *after* parameter has been handled.
189 Replace call and setup of parse_and_eval with new function
192 Tue Nov 12 09:40:07 1991 Fred Fish (fnf at cygnus.com)
194 * utils.c, rem-multi.shar: Remove fixed arg count version of
197 * altos-xdep.c, arm-xdep.c, coffread.c, command.c, convex-xdep.c,
198 core.c, dwarfread.c, gould-xdep.c, infcmd.c, language.c,
199 m88k-xdep.c, main.c, printcmd.c, pyr-xdep.c, source.c,
200 sun386-xdep.c, symm-xdep.c, umax-xdep.c, values.c, xcoffread.c:
201 Change all instances of use of fixed args concat() to variable
202 args concat() now located in libiberty.
204 Tue Nov 12 07:23:46 1991 John Gilmore (gnu at cygnus.com)
206 * Makefile.in: Add xcoffread.c, xcoffexec.c.
207 * xcoffread.c: New file for handling AIX mangled-coff files.

209 * buildsym.c: Add hooks for xcoffread.c.
210 * rs6000-pinsn.c, rs6000-tdep.c, rs6000-xdep.c, tm-rs6000.h,
211 xm-rs6000.h, rs6k-opcode.def, rs6k-opcode.h: New files.
212 * xcoffexec.c: New file for handling AIX shared libraries.
214 Mon Nov 11 19:14:31 1991 Fred Fish (fnf at cygnus.com)
216 * core.c: Minor rewording of message to user containing name of
217 (and possibly arguments to) the program that generated a core
220 * elfread.c: Remove the register_addr() stub now that it is no
223 * procfs.c: Move misplaced #endif for ATTACH_DETACH. Add new
224 fetch_core_registers() function for core file support.

228 * dwarfread.c (dwarf_psymtab_to_symtab): Remove leftover call
229 to do_cleanups() which resulted from a previous change.
231 * elfread.c: Re-enable compilation of register_addr() stub
232 whenever it is not supplied by coredep.c
234 Sat Nov 9 00:40:32 1991 John Gilmore (gnu at cygnus.com)
236 Add tracking of object files (that contain symbols) to gdb.
237 This includes a "struct objfile" that owns symtabs and psymtabs
238 that were read in from that binary file.
240 * symfile.h: Add struct objfile. Add pointer to the objfile
241 into the struct sym_fns.
242 Replace global `symfile' and `symfile_mtime' with
243 `symfile_objfile'. Add global object_files chain.
245 * symfile.c: Move param.h above symtab.h.
246 (sort_misc_function_vector): Add.
247 (syms_from_objfile): Was syms_from_bfd.
248 (symfile_open): Now returns objfile.
249 (allocate_objfile): New.
250 (free_objfile): New, replacing free_all_.*symtabs.
251 (symfile_init): Takes objfile arg, puts it in sym_fns result.

257 * dbxread.c: Make more errors into complaints.
258 (push_subfile, pop_subfile): Move to buildsym.c.
259 (dbx_symfile_read, dbx_symfile_init, fill_symbuf, read_dbx_symtab,
260 start_psymtab, psymtab_to_symtab_1, read_ofile_symtab,
261 dbx_psymtab_to_symtab, ): Use bfd ops, don't use file descriptor.
262 Pass objfile. Change callers.
263 (fill_symbuf, SWAP_SYMBOL): Take bfd as arg.
264 (read_dbx_symtab): Just wipe out new symbols, not all, on error.
265 (end_psymtab): Blow away psymtab if empty.

270 * buildsym.c (end_symtab): Pass objfile.
271 (dbx_lookup_type): Handle null typevector.
272 (dbx_alloc_type): Check file number, not sym number, for -1.
273 (find_symbol_in_list): Add for xcoffread.
274 (start_symtab): Default typevector is empty. Keep reusing same
276 (end_symtab): Take objfile argument and pass it to
277 allocate_symtab. Don't make a symtab if no blocks or symbols.
278 Handle empty typevector.
279 (push_context): New function for context stack nesting.
280 (read_type): Mark FIXME where we need to reintroduce type smashing.
282 * buildsym.h (pop_context): Macro, paired with push_context.
283 (subfile_stack): Move here from dbxread.c.
285 * coffread.c (end_symtab, read_coff_symtab): Take and use objfile arg.
286 (read_coff_symtab): Cleanup by freeing objfile, not all symtabs.

291 * dwarfread.c (scan_compilation_units, start_psymtab,
292 process_dies, end_symtab, dwarf_build_psymtabs,
293 read_lexical_block_scope, read_func_scope, read_file_scope): Take
294 and use objfile argument.
295 (psymtab_to_symtab_1, read_ofile_symtab): Don't take or use file
296 descriptor. Use BFD internal functions instead.
297 (end_symtab): Call global allocate_symtab.
299 * elfread.c, target.c: Minor changes to accommodate objfiles.
300 * symtab.h: partial_symbol_table has no symfile_name member now.

302 (struct symtab): Add objfile * and objfile_chain * of symtabs.
303 (struct partial_symtab): Add objfile * and objfile_chain * of
304 psymtabs. Remove symfile_name.
306 * symmisc.c: Lose free_all_symtabs, free_all_psymtabs.
307 (printsyms_command): Rename from print_symtabs. Add selective
308 listing if 2nd argument given. Print objfile info.
309 (printpsyms_command): Rename from print_partial_symtabs. Ditto all.
310 (printobjfiles_command): New; prints objfiles lists, and checks

313 * symfile.h, symfile.c, symtab.h: Lint
315 Fri Nov 8 23:38:48 1991 John Gilmore (gnu at cygnus.com)
317 * command.c: Include param.h.
318 * defs.h (warning_setup, warning): Declare.
319 * expprint.c (print_subexp, UNOP_MEMVAL case): Lint.
320 * inflow.c (new_tty): Use USE_O_NOCTTY #define.

324 Thu Nov 7 18:26:15 1991 Steve Chamberlain (sac at rtl.cygnus.com)
326 * Makefile.in: link with libiberty after libreadline, since
327 readline might want something in libiberty.
328 * m88k-xdep.c: Fixed the register offsets in the ptrace_user
329 struct for BCS 88k machines.
330 * xm-m88k.h: don't define USIZE if already defined.
331 * configure.in: Added delta88 target.
333 Thu Nov 7 04:51:19 1991 John Gilmore (gnu at cygnus.com)
335 * am29k-pinsn.c, am29k-opcode.h: Fix decoding of mtacc, dmac, fmac.
337 * tm-*.h: Remove READ_DBX_FORMAT, COFF_FORMAT, and
338 READ_MIPS_FORMAT, which have been unused since BFD. Still
339 remaining is COFF_NO_LONG_FILE_NAMES.
340 * tm-sun3.h, tm-altos.h: Remove detritus accidentally left from
341 function calling code moved to m68k-tdep.c.
343 Wed Nov 6 17:21:59 1991 John Gilmore (gnu at cygnus.com)
345 * coffread.c: Eliminate c_nsyms in favor of c_naux.
346 Complain if no auxents on .bf and .ef FCN symbols, and assume
347 lots of line numbers.
348 (init_linenos, enter_linenos): Use a sentinel at the end of the
349 read-in linenos, to make for a fast, safe loop-end test.
351 Wed Nov 6 02:54:08 1991 Steve Chamberlain (sac at cygnus.com)
353 * coffread.c (read_coff_symtab): coffread used to rely on the
354 x_sym.x_misc.x_lnsz.x_lnno field giving the # of linnos in a
355 function. Two of the formats I'm using (29k and 88k) don't seem to
356 set it. Ths patch to fcn_last_line and (enter_linenos) is an
357 attempt to use the actual size of the linno table in the file to set
358 the number of linenos to process.
360 Tue Nov 5 22:47:46 1991 Steve Chamberlain (sac at cygnus.com)
362 * Makefile.in: put a - infront of the mv y.tab.c c-exp.tab.c and
363 mv y.tab.c m2-exp.tab.c, so that if bison is used, and the files
364 are created in place, so the mv fails, then the make continues.
366 Tue Nov 5 16:47:47 1991 Per Bothner (bothner at cygnus.com)
368 Add C++ as a separate language.
369 * defs.h (enum language): Add language_cplus.
370 * dwarfread.c (end_symtab): Support language_cplus.
371 * c-exp.y: Add new struct language_defn cplus_language_defn.
372 Don't set c to be the default language (see main.c).
373 * c-exp.y (yylex): Only look for field of this if
374 language is C++. (First difference from C!)
375 * language.c: Add case branches for C++ (currently, all
376 the same as C). Also, add c++ to "usage" note for "set lang".
377 * valprint.c (typedef_print). Add case branches for C++.
378 * main.c (main): New way to set initial language: Look at
379 file extension of psymtab containing main(). (Same as we
380 do for symtabs, but avoid loading the symtab yet.)
381 * symtab.c: New routine find_main_psymtab(), used by main()
382 to set initial language.
383 * symfile.c (allocate_symtab): Move code for mapping file
384 extensions-> languages to new deduce_language_from_filename().
386 Fix a C++ problem when looking for methods in super-classes.
387 There was confusion between base and derived types.
388 * valops.c (value_fn_field): Change function interface.
389 * values.c: Use new value_fn_field interface.
391 Mon Nov 4 10:49:33 1991 Per Bothner (bothner at cygnus.com)
393 * infrun.c: Fixed typo in comment.
394 * utils.c: All the v*fprintf emulation is now in libiberty,
395 so we can get rid of some junk.
396 * xm-sun3os4.h, xm-sun4os4.h, xconfig/decstation, xconfig/i386sco,
397 xconfig/sun3os4, xconfig/sun4os4: Don`t need HAVE_STRSTR any more.
398 * m68k-pinsn.c (print_insn_arg): Support BB/BW/BL
399 type operands, as used by branch instructions.
400 * gmalloc.c: Fix prototype of memcpy.
401 * elfread.c: Comment out register_addr, since it conflicts
402 with the one in coredep.c.
403 * buildsym.h: Remove extern declarations of two functions
404 that are really static in buildsym.c.
405 * tm-mips.h: Add symbolic names for more registers.
406 * mips-xdep.c (store_inferior_registers): Use new register names.
407 * xm-mips.h: Simplify REGISTER_U_ADDR, since it is now
408 only used for core files, not ptrace. Therefore,
409 the KERNEL_U_ADDR hack is no longer needed.
410 The mapping to ptrace number is now in in mips-xdep.c.
411 * mips-xdep.c: Define REGISTER_PTRACE_ADDR (using the
412 mapping from the old REGISTER_U_ADDR), and use it
413 in {fetch,store}_inferior_registers.
414 * mipsread.c: Rename #include ecoff.h to new name coff-mips.h.
415 * mips-tdep.c (mips_push_dummy_frame, mips_pop_frame):
416 Save/restore FP regs correctly (?).
417 * dbxread.c: Remove duplicate define_symbol and type_synonym_name
418 (these had been previously moved to buildsym.c).
419 Hence, define_symbol becomes extern instead of static.
420 * buildsym.c (read_struct_type): Comment out bogus handling
421 of C++ operator methods. Minor hacking of reading of class
422 contexts. Make define_symbol non-static, so dbxread.c can call it.
424 Fri Nov 1 11:05:47 1991 John Gilmore (gnu at cygnus.com)
426 * mipsread.c (read_mips_symtab, read_the_mips_symtab): Use real
427 filename with error messages.
428 * stack.c (frame_select_command): Rename to select_frame_command
429 to avoid "fr" and "fra" having nonunique completions.
430 * symfile.c (sort_symtab_syms): Ignore sort of zero symtab *.
431 (symfile_init): Print file format name when unable to handle it.
432 (free_named_symtabs): Use BLOCKVECTOR rather than obsolete BLOCKLIST.
433 * symmisc.c (free_symtab): Only free linetable if nonzero.
434 * symtab.h: Remove obsolete BLOCKLIST macros.
436 Thu Oct 31 18:12:43 1991 Stu Grossman (grossman at cygnus.com)
438 * infrun.c (wait_for_inferior): another stepi/nexti fix. Ensure
439 that stop_step is 1 at bottom of main loop. I don't know why this
440 needs to be done, but it helps me sleep better at night.
442 Sun Oct 27 18:18:39 1991 Stu Grossman (grossman at cygnus.com)
444 * main.c (initialize_history): Read history after reading all
447 Sun Oct 27 14:09:25 1991 John Gilmore (gnu at cygnus.com)
449 * buildsym.c: Break out initial malloc sizes.
450 (record_line): Record directly in a subfile. Alloc on demand.
451 (compare_line_numbers): Add from xcoffread.c.
452 (end_symtab): New params say whether to sort pendings and
453 linetable. Patch block stabs if defined. Shrink linetable before
454 allocating the symtab.
455 * buildsym.h: Delete line_vector* and prev_line_number. Add
456 global_stabs and file_stabs for xcoffread.
457 * dbxread.c (start_subfile): Move to buildsym. Change above calls.
458 * symtab.h: LINETABLE(symtab) can now be null. Zap LINELIST.
459 * symmisc.c, symtab.c: Cope with null LINETABLEs.
461 * blockframe.c: Pass fromleaf to INIT_EXTRA_FRAME_INFO.
462 * tm-29k.h, tm-88k.h, tm-i960.h, tm-irix3.h, tm-mips.h, tm-pyr.h,
463 tm-sparc.h: Accept fromleaf parameter.
464 * c-exp.y (yyerror): Pass error message if given.
465 * configure.in: Add rs6000 host and target.
466 * inflow.c (new_tty): O_NOCTTY kludge for RS/6000.
467 * symfile.h (entry_point): Add.
469 Sat Oct 26 00:16:32 1991 John Gilmore (gnu at cygus.com)
471 * buildsym.c: New file. Breaks out symbol-table-building routines
472 from dbxread.c, so they can be shared with xcoffread.c.
473 * buildsym.h: New file. Declarations for buildsym.c users.
474 * dbxread.c: Remove large chunks into buildsym.c.
475 * Makefile.in: Add buildsym.c and buildsym.h.
477 * symfile.c (syms_from_bfd): New routine.
478 (add_symbol_file): Call it to do the real work.
479 (syms_from_bfd): Initialize entry_point before calling symfile_init.
480 * symtab.h, symfile.c, coffread.c, mipsread.c, dwarfread.c:
481 Avoid declaring or setting entry_point (symfile.h & symfile.c cope).
483 Fri Oct 25 10:58:16 1991 Mark Eichin (eichin at cygnus.com)
485 * cplus-dem.c (cplus-demangle): added support for templates, static
486 data, and the new (correct) mangling for destructors.
488 * dwarfread.c: (dwarfwarn): created a varargs version of
489 dwarfwarn, for non __STDC__ compilers.
491 * c-exp.y: (yylex): added match for "template" token.
492 (typebase): added TEMPLATE name '<' type '>' clause, for explicit
493 specification of template types.
495 * symtab.c: (lookup_template_type): new function for finding
496 templates in symbol table.
497 (type_name_no_tag): changed to explicitly check for s/u/e at the
498 beginning of the symbol - if it is a template, none of these will
499 be there (but the name will still contain spaces.)
501 Fri Oct 25 18:59:32 1991 Per Bothner (bothner at cygnus.com)
503 Various fixes to improve g++ debugging.
504 * symtab.h: Add is_const and is_volatile flags for each method.
505 These are bit fields - take their space from voffset,
506 which shrinks to 30 bits. Since voffset is now a bitfield,
507 make it unsigned for portability. This changes its interpretation
508 slightly: Static methods now have voffset 1 instead of -1,
509 and virtual offsets start at 2, not 1.
510 * symtab.c: Renamed gdb_mangle_typename to gdb_mangle_name,
511 since it now returns an entire magled method name, not just
512 the type part. This avoids some duplication.
513 It also allows us to correctly mangle const and volatile
514 methods (using the new is_const and is_volatile bit fields
516 * valprint.c (type_print_base), values.c (check_stub_method):
517 Simplify by using new gdb_mangle_name.
518 * values.c (value_headof): Fix to correctly handle single
519 inheritance (actually two fixes, either of which suffices).
520 * dbxread.c (read_struct_type): Handle const and volatile
522 * dbxread.c (read_struct_type): Yet one more place where
523 we must handle '\\' continuations.
524 * valprint.c (vtbl_ptr_name): Add final '\0'.
526 Fri Oct 25 16:06:38 1991 Stu Grossman (grossman at cygnus.com)
528 * tm-sparc.h, tm-68k.h (EXTRACT_RETURN_VALUE): fix output of
529 short return values for sparc and 68k. Patch from Paul Eggert.
531 * coffread.c, coredep.c, i386-xdep.c: install patches for
532 SysV/386 3.2 from Mauro DePalma.
534 Fri Oct 25 02:02:13 1991 John Gilmore (gnu at cygnus.com)
536 * core.c (core_file_info), exec.c (exec_file_info): Print file
537 type. Use printf_filtered.
539 * valops.c (value_fetch_lazy): Avoid 0-length fetches.
541 Thu Oct 24 23:06:40 1991 Fred Fish (fnf at cygnus.com)
543 * dwarfread.c: Add casts to remove compiler warnings.
545 * tm-3b1.h, tm-68k.h, tm-altos.h, tm-amix.h, tm-hp300bsd.h,
546 tm-hp300hpux.h, tm-isi.h, tm-news.h, tm-pn.h, tm-sun2.h,
547 tm-sun3.h: Remove locally duplicated code for calling functions
548 in the inferior. The only differences were in the specific trap
549 vectors used and whether or not an fpu was present. These are
550 now handled by appropriate definitions of BPT_VECTOR and
551 HAVE_68881 respectively. Other minor obvious cleanups.
553 * valops.c: Correct a minor misspelling.
555 * utils.c: Remove local BSD/USG hacks that are now in libiberty.
557 * dwarfread.c: Remove prototype for dwarfwarn. Does not work
560 Thu Oct 24 09:33:44 1991 John Gilmore (gnu at cygnus.com)
562 * stack.c (frame_command): Always print. Use new
563 frame_select_command to select a frame without printing.
565 * dwarfread.c: Use <varargs.h>, since <stdarg.h> is not portable.
567 Thu Oct 24 01:32:51 1991 Fred Fish (fnf at cygnus.com)
569 * dwarfread.c: New file for DWARF debugging format support.
571 * elfread.c: New file for ELF object file format support.
573 * procfs.c: New file for SVR4 /proc (process file system) support.
575 * tm-amix.h, xm-amix.h, tconfig/amix, xconfig/amix: New files for
578 * xm-svr4.h, tm-svr4.h: New files for SVR4 support.
580 * xm-m68k.h: New file for host machines with m68k cpu.
582 * Makefile.in: Add elfread.c and dwarfread.c to SFILES_MAINDIR.
583 Add elfread.o and dwarfread.o to OBS.
585 * symfile.h: Add "elf" to list of supported formats in comment.
587 * c-exp.y, defs.h, symtab.h, valprint.c: Add three new builtin
588 types to gdb, builtin_type_long_double, builtin_type_complex, and
589 builtin_type_double_complex. Add and use new TARGET_SHORT_BIT,
590 TARGET_INT_BIT, TARGET_LONG_BIT, TARGET_FLOAT_BIT,
591 TARGET_DOUBLE_BIT, TARGET_LONG_DOUBLE_BIT, TARGET_COMPLEX_BIT, and
592 TARGET_DOUBLE_COMPLEX_BIT, as the sizes in bits of the indicated
593 types on the target machine (ala the existing TARGET_LONG_LONG_BIT).
595 * infrun.c: When using SVR4 /proc interface instead of ptrace(),
596 call proc_set_exec_trap() to setup child to stop at first instruction.
598 * inftarg.c: When using SVR4 /proc interface, call proc_wait()
601 * m68k-tdep.c: Add new routines supply_gregset(), fill_gregset(),
602 supply_fpregset(), and fill_fpregset(), which are machine
603 dependent support routines for SVR4 /proc interface.
605 * utils.c: Add warning_setup() and warning(). Warning() behaves
606 the same as error() except that it returns normally rather than
607 jumping back to command level. Modules that don't want to call
608 warning() for some reason, but want to produce their own warnings,
609 can call warning_setup() to ensure compatibility with the way
610 warning() and error() deal with the terminal.
612 * symtab.c: Make internal errors produce more useful messages.
614 * tm-68k.h: Move code that is duplicated in almost every single
615 m68k based machine's configuration files to this common file.
616 Duplications in the configuration files still need to be removed
619 * infrun.c (child_create_inferior): System V versions must call
620 setpgrp() with no arguments, to comply with prototyping typically
623 * munch: Add support for SVR4 style nm output.
625 * dbxread.c, mipsread.c symmisc.c, symtab.c: Remove the object
626 file specific fields from the partial symbol table structure and
627 replace them with a pointer to private data for each different
628 flavor of object file reader to initialize appropriately.
630 Wed Oct 23 09:38:20 1991 John Gilmore (gnu at cygnus.com)
632 * xconfig/sun[34]os4: Add note about strstr botch on sunos4.0.3c
635 * mipsread.c (fixup_undef_type): New function. If a struct /
636 union / enum is defined in a header file but nowhere else used,
637 (by typedefing, pointer referencing or declaration) the mipsread code
638 builds the complete tree for the structure but leaves its code as
639 TYPE_CODE_UNDEF as it doesn't know what kind of aggregate it is.
640 Guess its type based on the details of the members.
642 Tue Oct 22 18:04:32 1991 Stu Grossman (grossman at cygnus.com)
644 * infrun.c (wait_for_inferior): Check return value from
647 Mon Oct 21 17:47:03 1991 Stu Grossman (grossman at cygnus.com)
649 * infrun.c (wait_for_inferior): fix stepi/nexti that was broken
650 by my last edit to this routine.
652 Mon Oct 21 14:27:43 1991 John Gilmore (gnu at cygnus.com)
654 * tm-sun3.h (FIX_CALL_DUMMY): problem with cross debugging.
655 FIX_CALL_DUMMY does unaligned accesses and/or forgets to byte swap
656 the values before putting them into the dummy code. (From Peter
659 Mon Oct 21 10:04:39 1991 Steve Chamberlain (steve at rtl.cygnus.com)
661 * configure.in: added ebmon target.
663 Wed Oct 16 22:49:58 1991 John Gilmore (gnu at cygnus.com)
667 * Makefile.in: Roll VERSION to 4.2.
668 * README, TODO, WHATS.NEW: Update.
670 * core.c (core_open): Improve error message for bad file.
671 Pass .reg virtual memory address to fetch_core_registers to help
672 it find the registers in the core-file header.
673 * coredep.c (fetch_core_registers): Take new argument, use it,
674 and pass it to register_addr to locate the block of registers.
675 * xm-mips.h: Update KERNEL_U_ADDR for new scheme. Cleanup a bit.
677 * dbxread.c (read_dbx_symtab, process_one_symbol): Handle
678 Sequent N_FN_SEQ like everybody else's N_FN.
680 * main.c: Circumvent SCO cc bug with #if !!defined(USG).
681 * tm-i386v.h: #endif guck.
682 * xconfig/i386*: Remove -Dgetpagesize()=4096 kludge.
683 * xconfig/i386sco: Add HAVE_STRSTR to avoid ANSI bdeath.
684 * xconfig/tahoe: Add REGEX, which seems to be missing.
686 * coredep.c: Add <sys/types.h> for SCOnix.
687 * dbxread.c (read_dbx_symntab): Avoid coredump on malformed file.
688 * printcmd.c (print_formatted): Flush output before disassembly.
690 Tue Oct 15 20:12:32 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
692 * doc/refcard.tex (sec "Working Files"): consistent metavars and
693 other improvements, due to comments by François Pinard
694 (pinard@iro.umontreal.ca)
696 * doc/gdb.texinfo (appendix "Installing GDB"): changes in
697 configure, and improvenets related to Pinard's refcard comments
699 Tue Oct 15 08:45:12 1991 John Gilmore (gnu at cygnus.com)
701 Changes from Fred Fish:
702 * tm-68k.h (FPI_REGNUM): Add.
703 * infrun.c (child_create_inferior): flush stdout and stderr
705 * configure.in: Handle amigados, amix hosts and targets.
706 * inflow.c: Handle TIOCGLTC_BROKEN for Amiga.
709 * values.c (show_convenience): Use printf_filtered.
710 * main.c (define_command): Check result of lookup_command for
712 (echo_command): Use printf_filtered, and force output out.
714 * dbxread.c (read_enum_type): Avoid Modula-2 kludge that breaks C
716 * i387-tdep.c (double_to_i387): Fix typo for double_to_ieee_extended.
717 * utils.c (_initialize_utils): If !ISATTY, don't paginate.
718 * configure.in, tconfig/decstation, xconfig/decstation: Rename
719 dec3100 to decstation.
721 Mon Oct 14 13:37:50 1991 Roland H. Pesch (pesch at cygnus.com)
723 * doc/gdb.texinfo: Catch up to changes recorded here in ChangeLog
724 (nodes Continuing and Stepping; Memory; Targets) clarifications
727 Fri Oct 11 23:27:06 1991 John Gilmore (gnu at cygnus.com)
729 * tm-{irix3,mips,nindy960,pn,symmetry,vx960}.h: Move
730 REGISTER_U_ADDR to corresponding xm- file. Sugg. by Peter Schauer.
732 * symmisc.c (print_partial_symtabs): Add printpsyms debug cmd.
734 * m68k-tdep.c (m68k_push_dummy_frame, m68k_pop_frame): Add
735 generic routines for calling inferior functions.
737 * blockframe.c (inside_main_scope, inside_entry_scope): New.
739 * copying.awk: Filter formfeeds out of copying & warrantee.
740 Make them available as `show copying' and `show warrantee' also.
741 * main.c (print_gnu_advertisement): Advt `show' commands.
743 Thu Oct 10 17:25:47 1991 John Gilmore (gnu at cygnus.com)
745 * mach386-xdep.c: Even when cross-compiling, leave in the
746 core-file reading code.
747 * core.c (get_core_registers): Avoid coredump if no .reg section.
749 Wed Oct 9 17:03:34 1991 John Gilmore (gnu at cygnus.com)
751 * mipsread.c, coffread.c: initialise TYPE_VPTR_FIELDNO to -1.
752 This avoids coredumps under `set print object on' in value_headof
753 (called erroneously by value_from_vtable_info) for `p &struct'
754 or `p *struct'. From Peter Schauer.
756 Mon Oct 7 00:06:52 1991 John Gilmore (gnu at cygnus.com)
758 * Makefile.in: Roll version to 4.1.2.
759 * dbxread.c: Use aout64.h, not a.out.gnu.h. Get external symbol entry
760 size from BFD (but, FIXME, we don't yet read external nlists's and
761 convert them to internal nlists's before handling them -- we still
762 assume they have the same size and alignment.) Use SET_NAMESTRING
764 * exec.c (exec_file_command): Move dead coff-encapsulation code
766 * m88k-tdep.c, m88k-xdep.c: Remove encap test and #inc <a.out.h>.
768 Fri Oct 4 22:30:06 1991 John Gilmore (gnu at cygnus.com)
770 * configure.in, tm-i386v.h, xm-i386v.h: Intel 386 Mach host port.
771 * xm-i386mach.h, mach386-xdep.c, xconfig/i386mach: New files.
773 Fri Oct 4 17:04:31 1991 Per Bothner (bothner at cygnus.com)
775 More patches from Peter Schauer <pes@regent.e-technik.tu-muenchen.de>:
776 * mips-xdep.c (store_inferior_registers): Don't try to
777 write the (pseudo) FP.
778 * mipsread.c (parse_partial_symbols): Improved algorithm for
779 setting pst->texthigh.
781 Fri Oct 4 16:47:32 1991 Roland H. Pesch (pesch at cygnus.com)
783 * doc/Makefile: make TEXINPUTS include . everywhere
785 Fri Oct 4 00:35:56 1991 John Gilmore (gnu at cygnus.com)
787 * coffread.c, dbxread.c, symfile.c, symmisc.c, symtab.h: Remove
788 vestiges of typevectors, which were for symsegs and are no longer
789 used. (From a question by Eliot Dresselhaus
790 <dresselh@RFT30.nas.nasa.gov>).
792 Thu Oct 3 09:33:26 1991 John Gilmore (gnu at cygnus.com)
794 * dbxread.c, coffread.c: static-ize functions that were
795 gratuitiously external. (From Fred Fish.)
797 * c-exp.y: sym->class to SYMBOL_CLASS (sym).
799 * dbxread.c (dbx_lookup_type): Keep doubling size of typevector
800 until it is large enough.
802 * dbxread.c (read_type): Handle error case slightly better.
803 Make complaint message not C++-specific.
805 Wed Oct 2 17:21:07 1991 Stu Grossman (grossman at cygnus.com)
807 * infrun.c (wait_for_inferior): Fix step/next so that you only
808 stop at the beginning of a new line. This fixes various problems
809 with for loops, nested if-else's and switch statements.
811 Tue Oct 1 06:33:55 1991 John Gilmore (gnu at cygnus.com)
813 * symtab.c (lookup_symtab_1, lookup_symbol): "fatal" errors
814 between symtabs and psymtabs become ordinary error()s.
816 * dbxread.c (read_dbx_symtab): Relocate end_of_text_addr
817 properly, making "end pc" correct in shared lib psymtabs.
818 (From Guy Harris <guy@auspex.com>.)
820 Mon Sep 30 13:15:31 1991 John Gilmore (gnu at cygnus.com)
822 * dbxread.c: Enable, but soften, const_vol_complaint.
823 (read_dbx_symtab): N_STSYM and N_LCSYM define static vars.
824 Ditto Gould N_NBSTS and N_NBLCS. Also, all types in the psymtab
825 should be file-scope, not global.
826 (read_struct_type): Remove ancient multiple-inheritance warning.
827 (read_range_type): Check base type, complain & patch if undefined.
828 * stack.c (frame_info): Demangle the function name in `info stack'.
831 Sat Sep 28 10:02:33 1991 John Gilmore (gnu at cygnus.com)
833 * eval.c (evaluate_subexp_for_address): Don't use
834 TYPE_POINTER_TYPE directly (it might be zero if this type has
835 never had a pointer created before); use lookup_pointer_type.
836 * symtab.c (lookup_method_type): Arguments were swapped in all
837 callers, so fix it here. I'm amazed this worked at all!
839 Fri Sep 27 18:09:31 1991 John Gilmore (gnu at cygnus.com)
841 * c-exp.y, m2-exp.y: Define more yysymbols that happen to be
842 "bss" rather than "data" symbols, but which still conflict.
845 * coffread.c (coff_symfile_read): Use xmalloc, not malloc.
846 * core.c (core_files_info): Shorten output.
847 * exec.c (exec_files_info): Ditto.
848 (build_section_table): Ignore zero-length sections.
849 * language.c, printcmd.c: Lint.
850 * language.h (get_frame_language): Declare.
851 * saber.suppress: update.
852 * stack.c (find_relative_frame): Remove complex code that was
853 #if 0'd, stick with simple code. Lint.
854 * saber.suppress: Update a bit.
855 * symfile.c (add_symbol_file_command): Add "?" to question.
856 * utils.c (parse_escape): Avoid \a due to bdead compilers.
857 * value.h: Declare typedef_print.
859 * valprint.c (val_print, type_print_base): TYPE_CODE_RANGE less
862 * nindy-tdep.c (nindy_frame_chain_valid): Use lookup_misc_func.
863 (Reported by Mark Peek <mark@imagen.com>.)
865 * solib.c (solib_map_sections): Relocate all sections, even
866 though only the text section's size is tracked. Mark ld_text
867 for eventual elimination as we generalize to N sections.
869 * infrun.c (wait_for_inferior): Don't check if the PC is in a
870 call_dummy if we were stopped by a random signal that is being
871 passed to the program. This produced wierd results when calling
872 functions in the inferior and signals (e.g. SIGALRM) were in use.
874 Tue Sep 24 18:05:30 1991 John Gilmore (gnu at cygnus.com)
876 * infrun.c (IN_SIGTRAMP): Not parenthesized properly.
877 Bugfix from Paul Eggert <eggert@twinsun.com>.
878 * tm-ultra3.h (IN_SIGTRAMP): Ditto.
879 * valprint.c (print_floating): Print 9 digits for IEEE floats.
882 Mon Sep 23 15:50:07 1991 John Gilmore (gnu at cygnus.com)
884 * Makefile.in: Roll VERSION to 4.1.1.
885 * source.c (line_info): Peter Schauer fixes a bug I introduced in
888 Fri Sep 20 16:10:52 1991 John Gilmore (gnu at cygnus.com)
892 * Makefile.in (VERSION): Set to 4.1.
893 * language.c (set_language_command): Print useful help message,
894 and restore the language string after giving help.
895 * valprint.c (typedef_print): Print typedef in C or M2.
896 * symtab.c (list_symbols): Use it.
897 * main.c (main): Avoid any output before (gdb) prompt when -q.
898 * language.c (set_language_command): Handle errors by restoring
899 the language string to its current state (fix from A. Beers).
900 * doc/gdbint.texinfo: Roll in information from README. Rearrange
901 "how to install" and "how to print the doc" stuff so it drops
903 * configure.in: Rename rtpc CPU to romp to match config.sub.
904 * README, WHATS.NEW, TODO: Update for gdb-4.1.
906 Fri Sep 20 17:39:14 1991 Roland H. Pesch (pesch at cygnus.com)
908 * doc/gdb.texinfo: Updates from ChangeLog. set/show write,
909 autoloading shared libs, copyright etc on GDB startup, clean up $_
910 and $__ index refs, set/show listsize and related updates to list
911 cmd. New host/target configs.
913 Fri Sep 20 15:46:00 1991 Roland H. Pesch (pesch at cygnus.com)
915 * doc/Makefile: generate aux version-no file doc/gdbVN.m4
916 from main Makefile.in version definition
917 doc/gdb.texinfo: use version recorded in doc/gdbVN.m4 for current
919 Makefile.in (setup-to-dist): generate doc/gdbVN.m4
921 * doc/gdb.texinfo: merge new language-switching and lang-specific
924 Fri Sep 20 15:00:57 1991 Per Bothner (bothner at cygnus.com)
926 * mcheck.c: Add __ONEFILE kludge to allow compilation by non-ANSI
927 compilers (which may lack stddef.h).
929 Fri Sep 20 13:29:42 1991 John Gilmore (gnu at cygnus.com)
931 * dbxread.c (read_dbx_symtab, process_one_symbol): N_FN and
932 N_WARNING are the same except for the N_EXT bit, so just use their
933 values alone, rather than OR-ing them with N_EXT.
935 Fri Sep 20 12:27:55 1991 Stu Grossman (grossman at cygnus.com)
937 * mipsread.c (parse_lines): Deal with negative extended line
940 * c-exp.y, m2-exp.y: #define yyerrflag and yynerrs to avoid
941 global symbol conflicts.
943 Fri Sep 20 02:28:15 1991 John Gilmore (gnu at cygnus.com)
945 * .gdbinit: Move 'set complaints' to top, so it runs even in
946 case we aren't debugging GDB.
947 * language.c (_initialize_language): Fix type check and range
948 check documentation strings.
949 * utils.c (!HAVE_VPRINTF): Define vfprintf as a function, so
950 language.c can use it. (Though language.c should really not be
951 handling warnings/errors the way it does, FIXME.)
952 * symtab.c (lookup_primitive_type): const lint.
954 Bugfix from Peter Schauer:
955 * source.c (lines_to_list): Make signed, to avoid comparison
956 going unsigned and complaining that -3 is too high for 21 lines.
957 * stack.c (lines_to_list): Ditto.
959 Thu Sep 19 23:33:41 1991 John Gilmore (gnu at cygnus.com)
961 * Makefile.in (HFILES): Add minimon.h.
962 (VERSION): Roll version number to 4.0.95.
963 (gdb.tar.Z, make-proto-gdb.dir, setup-to-dist, gdb-XXX.tar.Z):
964 New rules for building distributions. Normal distribution
965 is built by doing `make -f Makefile.in gdb.tar.Z' in the directory
966 one level up from here; it calls make-proto-gdb.dir to build a
967 directory `proto-gdb' which is an image of the release. The old
968 `gdb.tar.Z' rule still works too.

973 * doc/gdbint.texinfo: Reorder contents; reorganize new-host,
974 new-target, and new-config chapters; fix minor typos; come closer
975 to usual GNU markup conventions for @file @samp @code @var.
977 Thu Sep 19 17:04:12 1991 Per Bothner (bothner at cygnus.com)
979 Patches from Peter Schauer <pes@regent.e-technik.tu-muenchen.de>:
980 * mipsread.c (parse_partial_symbols): Enter the name of all
981 structs/unions... into the psymtab so we can access them if the
982 symtab is not read in.
983 * mips-tdep.c: Remove some unneeded #includes.

1095 Tue Sep 17 08:37:41 1991 John Gilmore (gnu at cygint.cygnus.com)
1097 Add Andrew Beers' changes for Modula-2 support. His ChangeLog
1098 entries are enclosed herein. Not all of these changes
1099 have been merged into the master GDB sources -- check the
1100 ChangeLog above here for the merge log.
1102 Mon Jun 3 17:05:45 EDT 1991
1104 m2-exp.y Created. Tested outside of GDB for a few days. Proper
1105 operators were added, C specific operators and tokens
1106 removed. yylex() revamped to some extent. Still things
1107 missing from the grammar, such as sets.
1108 Tested for two weeks in GDB v3.5.
1110 Tue Jun 11 17:23:48 EDT 1991
1112 m2-exp.y Added boolean constants TRUE and FALSE to the grammar
1113 so they are built-in. Sort of a hack.
1115 Fri Jun 14 12:53:51 EDT 1991
1117 m2-exp.y Added range checking for numeric constants. Any numeric
1118 constant is assumed to be of builtin type INTEGER unless:
1119 (1) it is octal or hexadecimal, in which case it is a
1120 CARDINAL; (2) it is too big to fit into an INTEGER, in
1121 which case it is a CARDINAL.
1122 eval.c Added simple range checking for +, -, and * on integers.
1123 Doesn't work very well for *, since 6 * 1,000,000,000 =
1124 1,705,032,704, which fails the simple test of result >=
1125 first_operand, no matter in what order the operands are.
1127 Tue Jun 18 14:11:30 EDT 1991
1129 Broke the parser into parts, one containing the C grammar and the other
1130 containing code to be shared by all of the grammars.
1132 The following files no longer exist:
1137 The following files were added:
1139 c-exp.y (The C grammar)
1140 m2-exp.y (The Modula-2 grammar)
1141 parser-code.c (Code that is shared by the above grammar)
1145 Makefile.dist Changed to reflect the above dependencies. NOTE: It is
1146 now necessary to use the Bison compiler compiler, since it
1147 will generate function/variable prefixes other than yy.
1149 Tue Jun 18 16:47:49 EDT 1991
1151 symtab.[ch] Added the external variable working_lang, than holds the
1152 value of the current working language.
1153 Added the ennumerated type language_mode, with the values
1154 language_auto and language_manual, the former meaning that
1155 GDB sets working_lang as needed, and the latter meaning
1156 that the value of working_lang is totally under user
1158 symtab.[ch] Added the Modula-2 pervasive types INTEGER, CARDINAL,
1159 REAL, BOOLEAN and CHAR. Also added the type codes
1160 TYPE_CODE_BOOL and TYPE_CODE_CHAR.
1161 utils.c Added set_language_command and show_language_command to
1162 implement the GDB support commands "set language" and
1164 expression.h A number of identifiers were added to the type exp_opcode
1165 to facilitate Modula-2 builtin functions, integer
1166 division, and array indexing.
1168 Wed Jun 19 13:25:58 EDT 1991
1170 language.h Added the macro STRICT_TYPE, which evaluates to non-zero
1171 if the language specified by working_lang requires the use
1172 of strict typing of expressions. Eventually, even this
1173 will be able to be changed by the user.
1174 Added the macro RANGE_CHECK, which evaluates to non-zero
1175 if the language specified by working_lang requires the
1176 checking of a value against the domain of its type.
1177 Eventually, even this will be able to be changed by the
1179 language.[ch] Predicates involving types (simple_type, ordered_type,
1180 same_type, integral_type, numeric_type, character_type,
1181 boolean_type, float_type) are added. These predicates are
1182 based on the current value of working_lang, and are handy
1185 Wed Jun 19 15:39:34 EDT 1991
1187 eval.c Added the function type_array_rank which computes the rank
1189 valarith.c Added the funtion value_bool, which when given a integer
1190 value.h value (ie. struct value *) as an argument, it returns a
1191 boolean value (ie. struct value *) true if that integer
1192 is non-zero, and a boolean value false otherwise.
1193 valprint.c Added cases for TYPE_CODE_BOOL, so Modula-2 BOOLEAN values
1194 will print out properly.
1196 Wed Jun 19 16:36:34 EDT 1991
1198 valops.c Added the function value_capitalize, which returns it
1199 value.h argument capitalized if its argument is a lowercase
1200 letter, or the argument unchanged if its argument is not a
1202 valarith.c Added the function range_check_p, which returns non-zero
1203 value.h if its value argument is between the integral bounds upper
1205 Added the function range_check_enum_p, which makes sure
1206 that its value argument is a valid member of the domain of
1208 Added the function range_check_range_p, which makes sure
1209 its value argument lies between the upper and lower bounds
1210 of its type argument, which must be a ranged type.
1211 Added the function check_array_index, which range and type
1212 checks an index of an array.
1213 Added the function value_multi_subscript, which computes
1214 array[idx1,idx2...idxN], given a value array and an array
1215 of values representing indicies.
1216 values.c Changed value_from_long to work with TYPE_CODE_CHAR and
1217 unpack_long to work with TYPE_CODE_BOOL and
1220 Wed Jun 19 18:04:08 EDT 1991
1222 symtab.c Stored pervasive types in a structure and make
1223 lookup_pervasive_type() a lookup function that was based
1224 on working_lang. If lookup_pervasive_type() returned
1225 non-zero, then that value was returned (a fix, since
1226 before it simply wouldn't return the pervasive type.)
1227 language.h Added the macro CAST_IS_CONVERSION, which evaluates to
1228 non-zero if the language specified by working_lang means
1229 "conversion" when it says "cast".
1230 valops.c Added the function value_real_cast(), which performs a
1231 value.h *cast*, not a *conversion*, which is what value_cast()
1232 does when it can. In particular,
1233 value_cast(<float_type>,4) = 4.0, while
1234 value_real_cast(<float_type>,4) = some mess.
1235 eval.c Modula-2 builtin functions implemented: ABS, CAP, CHR,
1236 parser-code.c FLOAT, HIGH, MAX, MIN, ODD, ORD, TRUNC, and VAL.
1237 expression.h Added macros MAX_OF_TYPE and MIN_OF_TYPE to work with MAX
1238 and MIN on integral types. *NOTE*: These are currently
1239 hardcoded to work only if there are 8 bits per storage
1241 eval.c Made logical functions call value_bool to return a
1242 properly typed boolean value, based on working_lang.
1244 Thu Jun 20 11:55:27 EDT 1991
1246 valprint.c Types now print out in a Modula-2 fashion. This works for
1247 the cases when the type is printed out step-by-step, that
1248 is, it doesn't work when the name of a structured type
1249 (which includes the keyword "struct", etc.) is simply
1251 FIXME: Perhaps this is bad. Parts of it seem to kludgey,
1252 since type specifications in C and Modula-2 are very
1253 different. The C printing of a type is very recursive,
1254 whereas in Modula-2 it is generally very simple. C has
1255 type prefixes and suffixes, which have no real analogue in
1256 Modula-2. Maybe type_print() should call a language
1257 specific type printer. This is also advantageous if we
1258 compile GDB to exclude some of the languages. We'll just
1259 leave those functions out.
1261 Thu Jun 20 16:57:10 EDT 1991
1263 dbxread.c When reading the complete symbol table in (via
1264 psymtab_to_symtab()), the number and types of function
1265 arguments are added to a function type. define_symbol()
1266 calls add_param_to_type() to accomplish this.
1267 Assumption: when we come across a function definition
1268 (N_FUN symbol with an 'f' or 'F' in the name), its
1269 arguments will appear before another function definition.
1270 When a function is found, a pointer to its type is placed
1271 in the global in_function_type. Changes that
1272 add_param_to_type() makes are to this global.
1273 valprint.c The type of a function now includes (for Modula-2) the
1274 types of its parameters.
1275 eval.c Type checking and a check for the proper number of
1276 arguments is now done for function calls. Not sure of the
1277 impact this has on C++ member function yet.
1279 Thu Jun 20 19:58:48 EDT 1991
1281 valprint.c Rewrote the type printer. Broke it into two language
1282 specific parts, adding the functions type_print_m2() and
1284 An unfortunate consequence is this: if you debugging a C
1285 program in Modula-2 mode (why?), info types does not work
1286 well with regular expressions, since the types are printed
1287 out in Modula-2 terminology, but stored in C terminology.
1288 language.[ch] Added the functions new_type_last(), type_keyword(), and
1289 type_sep() to aid in the printing of typedefs.
1290 symtab.c Made the printing of typedefs as language independent as
1291 possible through calls to new_type_last(), type_keyword(),
1294 Fri Jun 21 11:50:26 EDT 1991
1296 dbxread.c Check all incoming ennumerated types. If it looks like
1297 Modula-2's BOOLEAN type, then change the type_code of the
1298 type to TYPE_CODE_BOOL so we can process it as a boolean
1300 valprint.c Replaced some of the 0x%x with calls to sprintf and
1301 hexformat() in val_print().
1302 language.[ch] Added the function hex_to_string(), which converts its
1303 integral argument to a hexadecimal number (format is
1304 language based) and returns the result as a string.
1306 Mon Jun 24 12:25:07 EDT 1991
1308 valprint.c Some functions call type_print_1() directly, instead of
1309 value.h using type_print(), so they can specify where (column) to
1310 print things. Since type_print() takes care of language
1311 dependence, that needs to be called first. Added a
1312 parameter depth to type_print() (so it is now like
1313 type_print_1). Changed type_print to type_print_at, and
1314 made type_print a macro that passes a depth argument of
1316 symmisc.c Changed all calls to type_print_1 to calls to
1318 Makefile.dist Made it possible to build GDB for a specific set of
1319 depend languages. Do this by passing a definition for the macro
1320 LANGS to make. LANGS should be a string containing a
1321 space-separated list of language names (ie. LANGS="c m2").
1322 The default is to build all languages. Note that grammar
1323 files must follow the naming convention of <lang>-exp.y.
1324 gdb.lang This holds the current value of the LANGS macro. It is
1325 examined every time make is called, and is updated if
1327 eval.c Added #ifdef _LANG_<lang> to these files.
1328 expread.c Still need to add them to dbxread.c and coffread.c.
1336 Mon Jun 24 16:33:11 EDT 1991
1338 language.[ch] Added the functions hexformat_pre() and
1339 hex_to_string_pre(), which take a prefix argument to
1340 include in the format string. Thus, hexformat_pre("08") will
1341 return "0x08x" (if the working language is language_c).
1342 Made hexformat() and hex_to_string() calls to the above
1343 with "" as the prefix argument.
1345 am29k-pinsn.c, arm-pinsn.c, breakpoint.c, convex-tdep.c, exec.c, core.c,
1346 dbxread.c, i386-pinsn.c, i386-stub.c, i386-xdep.c, i960-pinsn.c,
1347 infcmd.c, inflow.c, m68k-pinsn.c, m68k-stub.c, m88k-pinsn.c,
1348 mips-pinsn.c, mips-tdep.c, ns32k-pinsn.c, printcmd.c, pyr-pinsn.c,
1349 pyr-tdep.c, pyr-xdep.c, remote-vx.c, remote.c, solib.c, source.c,
1350 stack.c, sun386-xdep.c, symfile.c, symm-xdep.c, symmisc.c, tahoe-pinsn.c,
1351 valprint.c, vax-pinsn.c
1353 Changed all occurences of 0x%[0-9]*l*x in printf format strings to
1354 calls to hexformat() and hex_to_string(). Format strings without
1355 the leading "0x" were ignored.
1357 depend Updated to take the above into account.
1360 Tue Jun 25 15:27:18 EDT 1991
1362 symtab.h Added the types range_mode_t, range_check_t, type_mode_t,
1363 and type_check_t to keep track of the current state of
1364 range and type checking.
1365 main.c Added the variables range_mode, range_check, type_mode,
1366 and type_check to record the current state of range and
1367 type checking. Added initialization code to main().
1368 language.h Changed the macros STRICT_TYPE and RANGE_CHECK to examine
1369 the above variables.
1372 Tue Jun 25 17:57:08 EDT 1991
1374 dbxread.c process_one_symbol() updates the variable (enum language)
1375 source_lang based on the extension of the filename
1376 contained in the N_SO sybmol that started this symtab.
1377 When end_symtab() is called, the value of source_lang is
1378 put into the language field.
1379 stack.c select_frame() sets working_lang (and possibly type_check
1380 and range_check) to the language field of the symtab
1381 associated with the frame that is selected if working_mode
1382 is language_auto. If working_mode is language_manual, a
1383 warning is printed and working_lang is not set.
1384 language.c Added the function set_type_range(), which sets the value of
1385 type_check and range_check (if their modes call for
1386 automatic setting) based on the current value of
1387 working_lang. A non-zero argument will cause the current
1388 settings to be output.
1391 Wed Jun 26 14:51:40 EDT 1991
1393 eval.c Added range checks on assignment.
1394 m2-exp.y Added the grammar for sets to the language. Currently,
1395 these do not do anything except print an error message.
1397 Wed Jun 26 17:01:04 EDT 1991
1399 m2-exp.y Added the ability for parse_number() to parse negative
1400 numbers. A global flag is set upon encountering a unary
1401 minus. This was done to make, for example, 1 parse as a
1402 CARDINAL, and not as an integer, per Wirth's examples in
1403 Programming in Modula-2 ed.4.
1404 valprint.c Added support for "set radix 2" by then setting
1405 output_format to 't'.
1406 eval.c Implemented range checking on subrange types. Added calls
1407 to range_check_range_p for BINOP_ASSIGN and BINOP_VAL.
1408 Implemented MIN and MAX for ennumerated types. The
1409 minimum value of an ennumerated type is defined by Wirth
1410 as the first identifier, and the maximum as the last.
1411 m2-exp.y Made octal numbers ending with "B" be characters and those
1412 ending with "C" be numbers, per Wirth's book. (p. 34)
1414 Thu Jun 27 14:11:52 EDT 1991
1416 stack.c select_frame() now only sets working_lang, it does not
1417 notify the user. If working_mode is language_manual, then
1418 a warning is issued once.
1419 main.c At the end of each call to execute_command(), working_lang
1420 is checked against the local static (enum language)
1421 current. If they differ and working_mode is
1422 language_auto, the new settings of language, type and
1423 range checking are printed out.
1424 stack.c Modified frame_info() to include the language of the
1425 current frame in the output of "info frame".
1426 language.[ch] Added the function language_str() which returns the name
1427 of the current language.
1429 Fri Jun 28 15:33:14 EDT 1991
1431 m2-exp.y Added the built-in procedures INC, INCL, DEC, and DECL to
1432 the language. INCL and DECL currently cause an error,
1433 since sets are not implemented yet. INC and DEC are
1434 implemented as PREINCREMENT/PREDECREMENT with one
1435 argument, and as ASSIGN_MODIFY with two arguments.
1436 eval.c Added type checking to the above cases.
1437 value.h Added not_lval_constant to the lval_type ennumerated type.
1438 not_lval_constant means that the value is a constant
1439 value; that is 3 or 'a' or TRUE, not as in a constant
1440 identifier. This is used to help coerce numbers such as 3
1441 to either signed or unsigned numbers.
1442 valops.c Added the function value_coerce_constants() which coerces
1443 constant integers as following: if one is a constant and
1444 the other is not, the constant's type is set to the type
1445 of the other argument. If both are constants and one is
1446 signed, the other is converted to a signed constant.
1448 Sat Jun 29 17:26:29 EDT 1991
1450 valarith.c Added a better range checker. It now checks range
1451 (successfully) on integral operations [+-] (signed and
1452 unsigned) for any C sized type. Still does not work well
1453 for multiplication.)
1454 int_in_size() returns an integer that is coerced to fit into
1455 specified number of bytes.
1457 Mon Jul 1 13:04:14 EDT 1991
1459 language.[ch] Added the function binop_result_type(), which returns the
1460 builtin (struct type *) type that would be the result of a
1461 binop on the two values V1 and V2.
1463 Wed Jul 3 19:22:53 EDT 1991
1465 source.c Extended source_info() to include the source language in
1466 the output from "info source".
1468 Fri Jul 5 13:48:52 EDT 1991
1470 utils.c Moved the support functions for the GDB set/show commands
1471 dealing with language into language.c.
1472 language.c Added the function language_info(), which displays info
1473 about the current working language, type and range check
1474 settings. Called via the GDB command "info language".
1475 Added an initialization routine _initialize_language(),
1476 that sets defaults for the language, type and range
1477 variables and sets up the new GDB commands.
1478 main.c Language setup moved to language.c.
1481 Mon Jul 8 10:10:22 EDT 1991
1483 valarith.c Debugged the range checker for arithmetic. Still does not
1484 work for multiplication very well.
1486 Mon Jul 8 12:40:37 EDT 1991
1488 language.[ch] Added the function value_true() which returns non-zero if
1489 its argument represents a boolean true value.
1490 breakpoint.c Changed breakpoint_cond_eval() to call value_true() to
1491 check the truth of an expression.
1493 Thu Jul 11 12:51:34 EDT 1991
1495 language.[ch] Added the predicate structured_type(), which returns
1496 non-zero if the argument is a structured type.
1497 Added the predicate pointer_type(), which returns non-zero
1498 if the argument is a pointer type.
1499 eval.c Added the ability to do addition and substraction on
1500 pointers and integers. This case simply bypasses the
1503 Thu Jul 11 14:41:42 EDT 1991
1506 Added the symbol N_DEFD (0x4a) which is a definition
1507 module dependency that is used by the GNU Modula-2
1508 compiler and the linker. It is not important to GDB,
1509 except that [dbx|coff|mips]read.c should ignore these
1512 Fri Jul 12 16:07:00 EDT 1991
1514 valprint.c Changed the TYPE_LENGTH(type) >= 0 to TYPE_LENGTH(type) >
1515 0 in val_print(). Also added statements to the else part
1516 to coerce type (argument to val_print) to a pointer type
1517 if it is an "array of unspecified length".
1518 valops.c Added the function value_m2_string(), which returns a
1519 (value) value which is a constant string, whose type is
1520 (ARRAY [0..n] OF CHAR). The length field of the type
1521 structure is set to zero, so it will be interpreted as an
1522 "array of unspecified length".
1523 stack.c Moved the language/frame mismatch check to
1524 main.c:execute_command().
1525 main.c The working language is recorded each time
1526 execute_command() is executed. If working lang has
1527 changed during its execution, then the new
1528 language/type/range info is printed out for the user. If
1529 the working language does not match the language of the
1530 frame, a warning is issued.
1532 Sat Jul 13 16:16:39 EDT 1991
1534 eval.c Moved all the type-checking stuff for operators to
1535 language.[ch] language.c. This is so we can keep language-specific
1536 stuff (like for what type operators are defined) in
1538 language.[ch] Added the function binop_type_check(), which checks to see
1539 if its two (value) arguments are type-compatible with its
1540 opcode argument. The opcode should represent an operation
1541 involving an operator. Also added the macro function
1542 unop_type_check, which calls binop_type_check with a
1543 NULL second argument.
1544 expprint.c Added Modula-2 operators to the op_print_tab, so info
1545 expression.h break works correctly. Also added "op_string", which
1546 returns the string corresponding to the (enum exp_opcode)
1547 opcode that is its argument.
1550 Sat Jul 13 18:26:18 EDT 1991
1552 coffread.c Added code to record the type of function arguments with
1553 each paricular function. Code is very similar to that
1555 dbxread.c Moved add_param_to_type() to symtab.c
1556 symtab.[ch] Added function add_param_to_type() from dbxread.c
1558 *** NOTE: The above additions have not been tested.
1560 Mon Jul 15 12:50:47 EDT 1991
1562 langauge.[ch] Added the functions type_error and range_error, which work
1563 like error() except if the type/range mode is set to
1564 *_mode_warn, then they do not do a return_to_top_level(),
1565 but merely print a warning.
1566 Also changed [set|show]_[type|range]_command() to support
1567 the new "warn" feature.
1569 Thu Jul 18 17:50:54 EDT 1991
1571 mipsread.c Added code to record the type of function arguments with
1572 each particular function. Code is very similar to that
1575 *** NOTE: The above additions have not been tested.
1577 Fri Jul 19 11:19:10 EDT 1991
1579 defs.h Added macros MAX_OF_SIZE, MIN_OF_SIZE, UMAX_OF_SIZE, and
1580 UMIN_OF_SIZE, which when given a size of a numeric type,
1581 return the maximum and minimum value it can hold. UMAX...
1582 and UMIN... return the result for unsigned types.
1583 symtab.h Added the macros MAX_OF_TYPE and MIN_OF_TYPE to operate on
1584 struct types. They call above macros.
1585 dbxread.c Renamed the MAX and MIN_OF_TYPE macros to ..._OF_CTYPE to
1586 avoid a name conlict with the above.
1587 c-exp.y Added range checking on numeric constants in
1588 parse_number() for completeness.
1589 valarith.c Made binop_user_defined_p() and unop_user_defined_p()
1590 return 0 if working_lang is not language_c.
1592 Thu Aug 8 14:17:22 EDT 1991
1596 breakpoint.c Documentation strings of some commands changed to
1597 eliminate the references to the C language where
1600 Tue Aug 13 15:48:03 EDT 1991
1602 m2-exp.y Added qualified identifiers to the grammar. The semantics
1603 are slightly different from those of the GDB operator ::
1605 m2-exp.y Added a rule to each grammar of the form: start ::= exp |
1606 type_exp, where type_exp is any valid type expression.
1608 eval.c Added the opcode OP_TYPE, and an error case in eval.c.
1609 printcmd.c Modified ptype_command() so it actually parses the input
1610 (necessary for type expressions with scope qualifiers).
1611 Added the function ptype_eval() which expects an
1612 expression composed of one OP_TYPE element.
1613 *.[ch] Replaced all occurences of parse_c_expression with
1615 *.[ch] Replaced all occurences of parse_c_1 with parse_exp_1
1617 [End of ChangeLog entries from Andrew Beers for Modula-2 support.]
1619 Mon Sep 16 17:19:46 1991 John Gilmore (gnu at cygnus.com)
1621 Small fixes from Peter Schauer:
1623 * infrun.c (child_attach): Lint.
1624 * solib.c (find_solib): Handle shared libs version 2.
1626 Small fixes from David Wood:
1628 * xm-ultra3.h (SYS_SIGLIST_MISSING): Typo.
1632 * remote-vx.c: Move <stdio.h> to top, for FILE. Fix from
1633 John S <basrai%kanga.dnet@c3po.sm-alc.af.mil>.
1635 * utils.c (wrap_here): Avoid wrap action of fputs_filtered if
1636 chars_per_line is at maximum (user typed `set width 0'). Fix
1637 from Andreas Schwab <schwab@ls5.informatik.uni-dortmund.de>.
1639 Tue Sep 17 17:31:04 1991 Stu Grossman (grossman at cygnus.com)
1641 * coredep.c: include ptrace.h where necessary.
1642 * mipsread.c(parse_lines): fix unsigned char problem that was
1643 messing up line numbers on SGI's and possibly other MIPS based
1645 * infrun.c (child_create_inferior): use better test to check
1646 return val from setpgrp().
1647 * tm-irix3.h, xm-irix3.h, tconfig/irix3, xconfig/irix3: add these
1648 for sgi/irix support.
1650 Wed Sep 18 04:33:31 1991 Per Bothner (bothner at cygnus.com)
1652 * mipsread.c (parse_symbol): Put non-static procedures
1653 in the global block.
1655 Fri Sep 13 00:14:52 1991 John Gilmore (gnu at cygnus.com)
1657 Patch together `text_start' and `text_end' for 29K port.
1659 * exec.c (exec_command): If NEED_TEXT_START_END, define the
1660 variables and set them based on the exec file.
1661 * am29k-tdep.c: declare text_start.
1662 * valops.c (call_function_by_hand): declare text_end.
1664 * inferior.h: Eliminate CANNOT_EXECUTE_STACK in favor of
1665 defining CALL_DUMMY_LOCATION as BEFORE_TEXT_END. This is
1666 because machines that do this will also have to know to
1667 set NEED_TEXT_START_END. Besides, it was a redundant way to
1669 * tm-29k.h, tm-convex.h, tm-np1.h: Eliminate
1670 CANNOT_EXECUTE_STACK, define CALL_DUMMY_LOCATION and
1671 NEED_TEXT_START_END.
1673 Thu Sep 12 00:22:24 1991 John Gilmore (gnu at cygint.cygnus.com)
1675 AMD 29000 changes from David Wood <wood@david.ultra.nyu.edu>:
1677 * Makefile.in (CLIBS): Put XM_CLIBS and TM_CLIBS at end.
1678 Pass MUNCH_DEFINE to munch whenever we run it.
1679 * am29k-pinsn.c (print_insn): Handle NOP specially. Avoid %#x
1680 format string; use 0x%x instead.
1681 * am29k-tdep.c: Use DUMMY_SAVE_GREGS and RETURN_REGNUM.
1682 * ultra-xdep.c, xm-ultra.h: New files for Ultracomputer host system.
1683 * xm-rtbsd.h: New host support for RT/PC running BSD Unix.
1684 * inflow.c: Handle `short' process group IDs.
1685 * infptrace.c (fetch_register): Support CANNOT_FETCH_REGISTER,
1686 and check for ptrace errors.
1687 * coffread.c (SDB_REG_TO_REGNUM): Define if not already.
1688 (coff_symfile_init): Initialize text_bfd_scnum.
1689 (read_coff_symtab): Use it to find the text [and absolute?] sections.
1690 * ../config.sub: Add vendor nyu and os "sym[1-9]*".
1691 * configure.in: Add hosts rtpc-*-* and a29k-*-*.
1692 Merge target arm case with other "easy" cases. Add target
1693 cases a29k-*-none (rehack of am29k), a29k-*-kern (remote to
1694 Ultracomputer kernel), and a29k-*-sym1 (ultracomputer OS's user
1696 * minimon.h, remote-adapt.c, remote-mm.c: Add.
1697 * munch: Cope with RT/PC putting fns in data segment.
1698 Restore ability to override `nm' by specifying MUNCH_NM.
1699 * xconfig/rtbsd, xconfig/ultra3: New host systems.
1700 * tconfig/a29k: Rename from tconfig/am29k. Add remote-mm
1701 and remote-adapt. Remove encapsulated coff #define's (the
1702 support should go in BFD, and gdb shouldn't know or care).
1703 * tconfig/a29k-kern: Same, but for remote kernel debugging.
1704 * tconfig/ultra3: For debugging user processes on Ultra3/Sym1.
1705 * tm-29k.h: Update BADMAG (though it should go away).
1706 Allow the register definitions to be overridden in another
1707 tm-file. Fix SR_REGNUM. Add a mess of _REGNUM's. Separate
1708 RETURN_REGNUM from GR96_REGNUM and DUMMY_SAVE_GREGS from
1709 DUMMY_SAVE_GR96, for handling kernel calling conventions
1710 that use GR64+ rather than GR96+.
1711 * tm-ultra3.h: New file, for use on Ultra3 Unix as well as for
1712 remote debugging of Ultra3 kernel. Includes tm-29k.h and
1713 overrides various things.
1715 * remote-mm.c (mm_attach, mm_wait): Handle attach like
1716 child_attach does, making a clean stop in the newly attached
1718 * remote-eb.c: Lint.
1720 * coffread.c: Make coffread independent of any particular
1721 variant of COFF. Avoid #include-ing any particular one except
1722 internalcoff.h. BFD now passes key values for symbol reading
1723 as part of its coff_data structure (LINESZ, SYMESZ, AUXESZ,
1724 and the symbol masks and shifts); use them.
1725 Remove obsolete end_of_text_addr.
1727 * exec.c: Remove unused include files.
1729 Wed Sep 11 19:38:44 1991 John Gilmore (gnu at cygint.cygnus.com)
1731 * Makefile.in (documentation targets): Pass $(M4).
1732 Bugfix from eggert@twinsun.com (Paul Eggert).
1734 * stack.c (down_silently_command): Check for stack existence.
1736 Tue Sep 10 23:08:29 1991 John Gilmore (gnu at cygint.cygnus.com)
1738 * Makefile.in (VERSION): Update to 4.0.3.
1740 Tue Sep 10 09:19:29 1991 John Gilmore (gnu at cygint.cygnus.com)
1742 * core.c (core_file_command): Print frame at coredump with
1743 its level number, by calling print_stack_frame.
1744 * frame.h: Add selected_frame_level, print_stack_frame.
1745 * frame.h, stack.c: Remove print_sel_frame, print_selected_frame.
1746 * convex-tdep.c, convex-xdep.c, infcmd.c, inflow.c, infrun.c:
1747 Change print_sel_frame and print_selected_frame callers to
1750 * dbxread.c (read_ofile_symtab): Avoid empty else clause.
1751 * symfile.c (free_named_symtabs): Ditto.
1752 * main.c (main): wrap_here needs an arg.
1753 * solib.c (find_solib): Avoid memory access if _DYNAMIC is zero.
1754 (solib_add): Avoid noise.
1755 (solib_create_inferior_hook): Lint.
1756 (sharedlibrary_command): Move dont_repeat to here.
1757 * utils.c (error): Call wrap_here to force buffered output.
1759 Small patches from Peter Schauer:
1761 * coffread.c (start_symtab): Free any existing line_vector before
1763 (read_coff_symtab): Ditto for type_vector.
1765 * source.c (lines_to_list): New variable, replacing function.
1766 (all uses): Use as variable.
1767 (_initialize_source): Add 'set listsize' and 'show listsize'.
1768 * utils.c (lines_to_list): Remove function.
1769 * stack.c (print_frame_info): Use as variable.
1770 * defs.h (lines_to_list): Remove declaration.
1772 Mon Sep 9 13:45:57 1991 John Gilmore (gnu at cygint.cygnus.com)
1774 * breakpoint.c (insert_breakpoints): Restore warning about
1775 the program might be running in another process, but only for
1776 systems with this brain death (#ifdef ONE_PROCESS_WRITETEXT).
1777 * xm-hp300bsd.h, xm-mips.h, xm-vax.h: Define it.
1779 * utils.c (error): if error_pre_print is set, print the string
1781 * main.c (main, print_gnu_advertisement, print_gdb_version):
1782 Reformat legalese so it always prints, but acts as an "I'm here"
1783 message while symbols are being read. If any errors occur,
1784 print a few newlines to set off the message and start it at the
1785 left margin. Remove mention of "help" command, and don't yak
1786 about symbol reading.
1787 (catch_errors): Error string is now printed first in case of
1789 * command.c (undef_cmd_error, lookup_cmd): On undefined command,
1790 suggest the "help" command.
1792 * Makefile.in (VERSION): Set to 4.0.2.
1794 Thu Sep 5 23:49:48 1991 John Gilmore (gnu at cygint.cygnus.com)
1796 * .gdbinit: Remove useless "rr" command. Set complaints
1797 to 1 for people debugging gdb.
1799 * breakpoint.c, remote-vx.c: Reword strings printed by
1800 catch_errors callers.
1802 Wed Sep 4 11:07:50 1991 John Gilmore (gnu at cygint.cygnus.com)
1804 * WHATS.NEW: "history write -> history save". Doc "write on/off".
1805 (Fix from kenc@viewlogic.com.)
1807 Fix some infrastructure to be able to cope with host and target
1808 machines with different sized basic types (ints, ptrs, etc).
1809 (Idea from pierre@la.tce.com (Pierre Willard).)
1811 * values.c (value_from_longest): Rename from value_from_long.
1812 Handle pointer types as well as integers, so that targets with
1813 different pointer sizes from the host can be accomodated.
1814 * breakpoint.c, convex-tdep.c, eval.c, expprint.c, printcmd.c,
1815 valarith.c, valops.c, valprint.c, value.h, values.c: Rename
1816 uses of value_from_long to value_from_longest.
1817 * eval.c, findvar.c, printcmd.c, valarith.c, valops.c: Pass
1818 the correct pointer type to value_from_long{est}.
1820 * doc/gdb.texinfo ($_, $__): Describe types of these variables.
1822 * remote-vx.c: Remove obsolete code for calling functions via
1823 vxworks kludge interface (it referenced value_from_long).
1825 * valops.c (value_string): Find malloc with lookup_misc_func, not
1828 Tue Sep 3 18:37:46 1991 John Gilmore (gnu at cygint.cygnus.com)
1830 Make writing to files work properly. (Fixes to BFD are also needed.)
1832 * core.c (core_open): Open file ourselves, read or r/w, depending on
1833 write_files. Use bfd_fdopenr.
1834 * gdbcore.h (write_files): New variable.
1835 * exec.c (write_files): Define variable, add set&show for it.
1836 (exec_file_command): Use write_files to open for read or r/write.
1838 Make shared library reading happen automatically. These changes
1839 are mostly from Peter Schauer <pes@regent.e-technik.tu-muenchen.de>.
1841 * inferior.h (stop_soon_quietly): Add to exported variables.
1842 * infrun.c (child_create_inferior): call solib hook, if defined.
1843 (child_attach): call solib hook, if defined.
1844 * solib.c: Include inferior.h. Add from_tty to so_list as kludge.
1845 (find_solib): Use lookup_misc_func rather than hand-rolled.
1846 (symbol_add_stub): New stub for catch_errors.
1847 (solib_add): Avoid output if !from_tty. Catch errors rather
1848 than just calling symbol_file_add and bombing.
1849 (solib_create_inferior_hook): Interface with the target process
1850 to let it read and alloc shared libs, then figure out what it did.
1852 * core.c (validate_files): Fix typo, soften warning.
1853 (Fix from Hiroto Kagotani <kagotani@cs.titech.ac.jp>.)
1855 * utils.c (fputs_demangled): Avoid duplicate printing if
1856 demangling is off. (Fix from J.T. Conklin <jtc@cayenne.com>.)
1858 * infrun.c (proceed): Cast -1 to (CORE_ADDR) before comparing.
1859 (Fix from pierre@la.tce.com (Pierre Willard).)
1861 * main.c (catch_errors): Change argument to a char * from an int,
1862 since a char * can point to a struct full of glop, but an int
1863 is not guaranteed to be able to hold a pointer.
1864 * breakpoint.c (breakpoint_cond_eval, bpstat_stop_status,
1865 breakpoint_re_set_one, breakpoint_re_set): Adapt.
1866 * core.c (core_open, solib_add_stub): Adapt.
1867 * remote-vx.c (symbol_stub, add_symbol_stub, callers): Adapt.
1869 Wed Aug 28 18:18:05 1991 John Gilmore (gnu at cygint.cygnus.com)
1871 * Makefile.in: Update VERSION to 4.0.1. Evade GNU Make bug
1872 by adding .NOEXPORT target.
1874 Fri Aug 23 17:14:25 1991 John Gilmore (gnu at cygint.cygnus.com)
1878 * Makefile.in (VERSION): Roll to 4.0.
1879 (gdb.tar.Z): Make refcard.ps as well, for shipment.
1881 Fri Aug 23 14:07:09 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1883 * doc/gdb.texinfo: minor rewordings, crossref to ptype from print,
1886 * doc/Makefile, Makefile.in: generate "gdb-all.texi" rather than
1889 * doc/rdl-apps.texi: renamed from rdl-apps.texinfo
1891 * Makefile.in, doc/Makefile, doc/.Sanitize, doc/gdb.texinfo:
1892 reflect above name change
1894 * WHATS.NEW: correct pointer to refcard.
1896 * doc/gdb.texinfo: update New Features, Installing
1898 * doc/gdbint.texinfo: add short description of configure +template
1900 Fri Aug 23 11:46:08 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1902 * doc/gdb.texinfo: update, fix bugs in "Installing" appendix
1904 Fri Aug 23 01:02:00 1991 John Gilmore (gnu at cygint.cygnus.com)
1906 * Makefile.in: Add config.sub, make doc/rdl-apps.texinfo for
1907 tar file, add dependencies for referenced doc files.
1909 Thu Aug 22 22:17:06 1991 Stu Grossman (grossman at cygint.cygnus.com)
1911 * coffread.c, symfile.c, stack.c: saberized.
1913 Thu Aug 22 16:20:27 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1915 * doc/refcard.tex: permuted Essential Commands sec
1917 * doc/gdb.texinfo: new C++ chapter; revised installation appendix;
1919 set/show symbol-reloading
1920 default set complaints 0
1922 RET-repeat disabled after prompted long displays
1923 processID (attach) interpretation of 2nd GDB cmdline arg
1925 Thu Aug 22 14:05:47 1991 Stu Grossman (grossman at cygint.cygnus.com)
1927 * expread.y, coffread.c, dbxread.c, target.c, mem-break.c,
1928 cplus-dem.c, values.c, valprint.c, symfile.c, remote.c,
1929 breakpoint.c, main.c: lint.
1931 Thu Aug 22 02:02:26 1991 John Gilmore (gnu at cygint.cygnus.com)
1933 Install new configuration scheme for GDB and friends.
1935 * config.sub: Translate ordinary names to three-part names.
1936 * configure: Use three-part names internally.
1937 * configure.in: Translate three-part names to filenames.
1939 * README, WHATS.NEW: Update for gdb-4.0.
1940 * Makefile.in: Roll VERSION to 3.99.
1942 Wed Aug 21 18:21:09 1991 John Gilmore (gnu at cygint.cygnus.com)
1944 * infptrace.c (KERNEL_U_ADDR_BSD): Include a.out.gnu.h.
1945 * i960-tdep.c, m68k-tdep.c, sparc-tdep.c, tm-i960.h,
1946 tm-m68k.h, remote-nindy.c: Change ext_format_XXX structs
1947 to single structures rather than arrays; when passing
1948 their address, use &. This avoids trouble with bdead compilers.
1949 * mcheck.c: Don't include <stdlib.h>; just declare "void abort();"
1950 instead. This avoids portability headaches.
1951 * mips-tdep.c (mips_do_registers_info): Only print FP regs if
1953 * source.c (open_source_file): Avoid ANSI const bdeath by
1954 skipping declaration and then casting result value.
1955 * tm-hp300bsd.h: Clarify comment.
1956 * utils.c (strstr): Result is const char *; ANSI bdeath.
1957 * xm-hp300bsd.h: Define HOST_BYTE_ORDER. Redefine INT_MIN,
1958 since system include file defines it differently from "defs.h",
1959 though the two are equivalent for our purposes.
1960 * tconfig/hp300bsd: Add m68k-tdep.o.
1962 Tue Aug 20 16:01:11 1991 John Gilmore (gnu at cygint.cygnus.com)
1964 * tconfig/sun*4: Remove warnings about system assembler.
1966 Mon Aug 19 13:44:46 1991 John Gilmore (gnu at cygint.cygnus.com)
1968 * mcheck.c: Avoid warning about undeclared abort fn.
1969 * tm-sparc.h (PC_ADJUST): Avoid calling error() from this;
1970 it causes recursive calls to error() when used in cleanups.
1971 To do so requires that we make it a function, so we do.
1972 * sparc-tdep.c (sparc_pc_adjust): New implem of PC_ADJUST.
1973 * utils.c (do_cleanups): Remove the current cleanup from the
1974 chain *before* calling it, in case error() is called from it.
1975 The result won't be pretty, but won't be an infinite loop either.
1977 Mon Aug 19 00:41:04 1991 Michael Tiemann (tiemann at cygint.cygnus.com)
1979 * dbxread.c (read_struct_type): Grok anon structs for C++.
1980 (vb_name, vptr_name): Null terminate these strings.
1982 Fri Aug 16 08:31:03 1991 John Gilmore (gnu at cygint.cygnus.com)
1984 Minor bug fixes from BSD Net2 gdb:
1986 * blockframe.c (get_prev_frame_info): If FRAME_CHAIN_COMBINE
1987 returns 0, there is no previous frame.
1988 * breakpoint.c (commands_command): If !from_tty, don't call
1989 input_from_terminal_p().
1990 * dbxread.c (record_misc_function): Speed up slightly.
1991 (compare_psymbols): Ditto.
1992 * infcmd.c (do_registers_info): Take a second argument to
1993 determine whether to print float registers. "info registers"
1994 does not do so anymore. "info all-registers" does, now.
1995 * mips-tdep.c, pyr-tdep.c (xxx_do_registers_info): Take second
1997 * tm-mips.h, tm-pyr.h (DO_REGISTERS_INFO): Pass second arg.
1998 * inflow.c (initialize_inflow): Set tflags_ours correctly.
2002 * breakpoint.c (bpstat_do_actions): Use a cleanup to restore
2003 executing_breakpoint_commands if we are interrupted by error.
2004 * coffread.c (init_lineno): Avoid problem with zero-sized linetab
2005 versus malloc/free. From: john@labtam.labtam.oz.au (John Carey).
2006 * core.c (solib_add_stub, core_open): Call SOLIB_ADD inside a
2007 catch_errors() so we can setup the frame regardless of whether
2008 the shared libs work.
2009 * ieee-float.c (double_to_ieee_extended): Get exponent from
2010 right place in little-endian systems. From John Carey.
2012 Thu Aug 15 18:43:57 1991 John Gilmore (gnu at cygint.cygnus.com)
2014 * main.c: Remove unused terminating_signals and catch_termination().
2015 (long_options): Terminate with a zero element.
2016 [Bugfix from Atsuo Kawaguchi <atsuo@hark86.harl.hitachi.co.jp>.]
2017 (gdb_readline): Make call-compatible with readline.
2018 (init_signals): Improve comments re vfork vs. signal.
2020 * utils.c (prompt_for_continue): Use new gdb_readline().
2021 If we prompt for continuation, we don't let CR repeat the previous
2022 command, once we get back to a prompt. It's too easy to keep
2023 hitting CR, expecting "--more--" prompts, and have some long
2024 command start repeating on you.
2026 Tue Aug 13 16:17:56 1991 John Gilmore (gnu at cygint.cygnus.com)
2028 * blockframe.c (frameless_look_for_prologue): Speed up by
2029 calling SKIP_PROLOGUE_FRAMELESS_P if it's defined.
2030 * tm-sparc.h (SKIP_PROLOGUE, SKIP_PROLOGUE_FRAMELESS_P):
2031 Define two variants, one faster.
2032 * sparc-tdep.c (sparc_frame_chain): Use target_read_memory
2033 and return zero, rather than giving an error.
2034 (setup_arbitrary_frame): Initialize the PC in the new frame.
2035 (skip_prologue): Add a second arg saying whether we're just
2036 checking for a frameless function or not.
2038 * core.c (core_open, core_close, core_xfer_memory): Move
2039 section table pointers and bfd* into the target_ops.
2040 (core_open): Allow errors in shared lib reading, etc.
2041 (core_files_info): Describe shared library sections.
2043 * exec.c (exec_open, exec_close, exec_xfer_memory, xfer_memory,
2044 exec_files_info, set_section_command): Move section table
2045 pointers and bfd* into the target_ops.
2046 (add_to_section_table): Add BFD to section table.
2048 * target.c (target_xfer_memory, target_info): Pass target to
2049 xfer_memory and target_info functions.
2052 * gdbcore.h: Move struct section_table.
2053 * target.h: New home of struct section_table.
2055 * solib.c (solib_add): New argument is the target_ops whose
2056 section list is to be added to, if any. Reallocate the
2057 sections in that target to add any that come from shared libs.
2058 (throughout) so_sections renamed to sections.
2059 (solib_xfer_memory): Deleted.
2060 * tm-sunos.h (SOLIB_ADD): Add target argument.
2061 (SOLIB_XFER_MEMORY): Delete.
2063 * core.c, exec.c, inftarg.c, remote-eb.c, remote-nindy.c,
2064 remote-vx.c, remote.c, target.c, target.h: Remove add_syms vector
2065 from target_ops. It's the same on all targets. Add two section
2066 pointers to target_ops.
2068 * stack.c (find_relative_frame): Dump ancient algorithm for
2069 "down", just use handy "next" pointers.
2070 (frame_command): Don't error if there is no stack; let user
2073 * inflow.c (new_tty_prefork, new_tty): New prefork routine
2074 modifies static state in the parent process; new_tty itself
2075 runs in the child and modifies the child's file descriptors
2076 to match the saved static state.
2077 * infrun.c (child_create_inferior): Call new_tty_prefork,
2080 * infptrace.c (child_xfer_memory): Add ignored target arg.
2081 * remote-eb.c (eb_xfer_inferior_memory): ''
2082 * remote-nindy.c (nindy_xfer_inferior_memory): ''
2083 * remote-vx.c (vx_xfer_memory): ''
2084 * remote.c (remote_xfer_memory): ''. Rename from
2085 remote_xfer_inferior_memory.
2087 * main.c (main): Only try to attach "corefile" argument if
2088 it starts with a digit.
2090 * symfile.c (symbol_reloading): New "set/show" variable.
2091 (symbol_file_add): Shorten message about symbol reading.
2092 (add_symbol_file_command): Merge with add_syms_addr_command,
2093 since this should work on all targets now.
2094 (stop_whining): Default to zero, to shut up complaints
2095 about bad symbol tables on many systems.
2096 (free_named_symtabs): Just exit unless symbol_reloading.
2098 * xm-sun3os4.h, xm-sun4os4.h: Define BROKEN_LARGE_ALLOCA,
2099 and add comment explaining shared library screw.
2101 * source.c: #if defined => #ifdef.
2103 Thu Aug 8 12:23:19 1991 John Gilmore (gnu at cygint.cygnus.com)
2105 * doc/gdbint.texinfo: Improve doc on porting to new OS's.
2107 Tue Aug 6 17:16:15 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
2109 * doc/rdl-apps.texinfo: provide default readline-appendix finder
2110 (doc/Makefile knows how to make one for local config)
2112 * Makefile.in: use doc/Makefile for doc targets
2114 * doc/Makefile: GDB documentation now has its own Makefile
2115 doc/refcard.tex: renamed from "gdbrc.tex"
2116 doc/.Sanitize: add Makefile; recognize renamed refcard.tex
2117 doc/gdbint.texinfo: add markup in "Cleanups" chapter
2120 Fri Aug 2 00:13:06 1991 John Gilmore (gnu at cygint.cygnus.com)
2122 * values.c (baseclass_addr): When reading target memory, use the
2123 length of the basetype, not the upper type. We've only malloc'd
2124 enough space for the basetype, leading to errors in free().
2126 * expprint.c (print_subexp): Print UNOP_MEMVAL of an OP_LONG that
2127 ends up as a function specially, since we know the actual type of
2128 the pointed-to address. This (somewhat) fixes display of
2129 expressions that include misc_function_vector names. Try `cond 1
2130 !strcmp("a","b")' then `i b'.
2132 * infrun.c: Move DO_DEFERRED_STORES from proceed() to resume().
2133 The child can be proceeded from inside wait_for_inferior in
2134 evaluating breakpoint conditions, and DO_DEFERRED_STORES was
2135 getting skipped in that case.
2137 * expprint.c (print_subexp): Use filtered output, since the
2138 subroutines we call use it, otherwise the output is horribly
2139 mangled, since output of wrappable stuff comes out late.
2141 * Makefile.in: Bump VERSION to 3.98.1
2143 * infrun.c (child_create_process): Use execlp to find the
2144 shell to exec our target program. This requires some fiddling
2145 with `environ' since there is no execlpe().
2147 Thu Aug 1 15:35:17 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
2149 * Makefile.in, doc/gdbrc.tex, doc/rc-* (new files):
2150 Minor rearrangement of refcard permits two new make targets--
2151 gdbrc.dvi DVI output for refcard, using CM fonts
2152 gdbrc.ps PostScript refcard, using PS fonts
2154 Wed Jul 31 16:46:21 1991 John Gilmore (gnu at cygint.cygnus.com)
2158 * TODO, Projects, WHATS.NEW, README: Update for gdb-3.98.
2159 * Makefile.in (gdb-all.texinfo): Avoid touching file if M4 dies.
2161 Wed Jul 31 16:35:58 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
2163 * doc/gdb.texinfo: last changes for release.
2164 Minor typo and formatting fixes; incorporated most fixes remaining from
2165 filed mail commenting on earlier drafts.
2167 Added warnings: pipes don't work in run command;
2168 conditions are converse of assertions;
2169 step over fn without debug info goes to next fn;
2170 vars may have "wrong" values near fn entrance, exit
2172 Added example from Kingston on printing repeated nonadjacent values
2174 Added explicit mention that in Emacs gdb mode C-c and C-z are like
2175 shell mode for signals
2177 Renamed "Stepping and Continuing" to "Continuing and Stepping" so it
2178 doesn't sound so much like its parent "Stopping and Continuing"; also
2179 moved entries on continue to top of section, so they don't get lost.
2181 Improved installation directions in appendix, added manual formatting
2184 Tue Jul 30 17:26:39 1991 John Gilmore (gnu at cygint.cygnus.com)
2186 * configure.in: Remove xm.h and tm.h even if we aren't linking
2187 new ones, so "./configure sun4; ./configure none" does the right
2188 thing. Assume that alldeps.mak and depend are already built in
2189 srcdir, and avoid running "make" (particularly "make depend",
2190 which involves "gcc") from inside configure. Build Makefile
2191 directly rather than building Makefile.conf first.
2192 * configure: Regenerate with above changes.
2193 * Makefile.in: Use $(BISON) to find bison. Roll VERSION
2194 to 3.98. Revise gdb.tar.Z procedure to produce a file
2195 called gdb-$(VERSION).tar.Z but which unpacks into a
2196 directory called "gdb". Move non-source files out of
2197 $(SFILES_SUBDIR). Pretty up alldeps.mak with comments.
2198 (depend): Don't try to do "gcc expread.y".
2199 (expread.o): Update dependencies by hand.
2201 Mon Jul 29 15:21:09 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
2204 Fixed a variety of small typos that prevented info from formatting
2205 cleanly; altered too-long heading for GPL Appendix, as discussed
2206 w/RMS; Changed date on cover to July 91.
2208 Fri Jul 26 13:20:02 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
2211 (1) Applied some fixes due to comments from Larry Breed (easier ones
2212 through chapsec 5.2)
2213 (2) Eliminated use of @footnote---had my doubts about it anyways, and
2214 it's broken in latest texinfo
2215 (3) Introduced *some* use of [] for optional arguments, where
2216 explanation is not simpler by listing cmd w arg and cmd w/out arg
2217 separately. Still not using @deffn.
2218 (4) Dropped in GPL-2. NOTE: one of GPL-2 or texinfo is broken; a
2219 couple of headings are too long. Need patches to texinfo or revision
2222 * Partial update to README (which still needs work for this
2223 release!): (1) use of configure corrected for new script,
2224 (2) "make gdb.dvi" and "make gdb.info" mentioned.
2226 Wed Jul 24 06:44:02 1991 John Gilmore (gnu at cygint.cygnus.com)
2228 * symtab.c (lookup_symbol): Don't complain right off about
2229 no debug symbols; use the misc function vector first.
2230 (list_symbols): Use misc function vector to find symbols
2231 that don't have debug info, and print them.
2232 (find_pc_symtab): Temporarily avoid fatal() when psymtab
2233 PC range doesn't match symtab PC range, as it does on the
2234 MIPS because our symtab reading isn't perfect.
2236 * dbxread.c (dbx_symfile_read): Make warning about
2237 "no debug symbols" slightly nicer.
2239 * source.c (select_source_symtab): If "main" symbol exists,
2240 but decode_line_spec can't find line info, don't just return
2241 a zero; try other source symtabs or give an error.
2243 * mipsread.c (parse_partial_symbols): Sort the psymtabs by
2244 their low addresses first, then rip through fixing high addrs.
2246 * ns32k-opcode.h (sfsr): Bugfix from Rune Nerg}rd,
2247 <runene@ifi.uio.no>.
2248 (NS32K_SVC_IMMED_OPERANDS): Reverse the #ifndef.
2250 Tue Jul 23 18:52:43 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
2252 * Minor, mostly mechanical, cleanup of doc subdir for clean
2253 makeinfo'ing and TeXing; also ensured gdb-all.texinfo (post-m4)
2254 and gdb.info (post- texinfo2 makeinfo) generated for distribution.
2256 Sun Jul 21 03:54:52 1991 John Gilmore (gnu at cygint.cygnus.com)
2258 Mostly MIPS and general symbol-reading fixups.
2260 * doc/gdbint.texinfo: Add documentation on symbol-reading
2263 * mipsread.c: Remove kludges around #include "ecoff.h".
2264 Remove redefinitions of a_magic, etc, no longer used.
2265 (parse_symbol, ): Convert "Internal:" printfs to complain()ts.
2266 Fix global overview comments to match symfile.c protocol.
2267 (mipscoff_new_init): Eliminate cur_hdr if we have one.
2268 (mipscoff_symfile_read): Eliminate unused code. Avoid
2269 sorting all the symtabs, when all we have read here is psymtabs.
2270 The symtabs are sorted as they are created anyway. Tell
2271 condense_misc_bunches whether we're mainline.
2272 (psymtab_to_symtab_1): Pass filename when recursing, to make
2273 stack trace more informative.
2274 (parse_partial_symbols): Assume cur_hdr as argument.
2275 (read_mips_symtab): Don't clobber cur_hdr, so it can be freed.
2276 Pass cur_hdr implicitly to parse_partial_symbols. Avoid checking
2277 the TYPE_NAME of char *, since that's done in symfile.c.
2278 (free_numargs, parse_symbol, add_symbol, add_block,
2279 shrink_linetable): Declare these fns void.
2280 (upgrade_type): Convert tree of if's to switch. Clean up
2281 bogus "off == 0" handling with a complaint. Avoid setting
2282 field bitpos and bitsize of array with lower and upper bounds.
2283 Check specified bitsize of elements against their actual type's
2284 bitsize, and complain if different. Complain about unknown
2286 (parse_fdr): Don't assume sizeof(char *) == sizeof (struct *).
2287 (psymtab_to_symtab_1): Print names of subsidiary files that
2288 are being read in. FIXME, we read far too many files. This code
2289 is not the problem, the problem is in parse_fdr where the psymtabs
2291 (cross_ref): Result should indicate that we used one aux entry
2292 normally, or two if we encountered a "next" entry. This used
2293 to leave the caller pointing at the wrong aux entry.
2294 (add_symbol): If overflowed cur_block, reallocate it larger,
2295 chase all pointers to it, and complain(), rather than clobber memory.
2296 (shrink_block): Use xrealloc rather than xmalloc-and-copy.
2297 (new_field): Only allocate one field initially, not two.
2298 Pull ++ out of macro argument. Simplify.
2299 (_initialize_mipsread): Avoid initialization of importd
2300 global_psymbols and static_psymbols.
2302 * symfile.c (psymtab_to_symtab): Depend on XXX_psymtab_to_symtab
2303 to properly set pst->symtab; avoid searching for it.
2304 (symfile_fns): Improve comments, add a FIXME.
2305 * dbxread.c: Update comments to reflect symfile protocol.
2306 (read_ofile_symtab, end_symtab): Return the symtab.
2307 (psymtab_to_symtab_1): Set pst->symtab.
2309 * coffread.c (coff_symfile_read): tell condense_misc_bunches
2310 whether we're mainline.
2312 * symfile.h (sym_fns): Remove unused sym_discard member.
2313 * coffread.c, mipsread.c, dbxread.c: Remove XXX_symfile_discard.
2315 * mtrace.c (mtrace): Take effect if mallwatch is set, even if
2316 the environment variable is not.
2317 * infcmd.c (finish_command): Use filtered printfs.
2318 * cplus-dem.c: Add struct tags to a few unnamed structs.
2319 * valops.c (value_coerce_array): Improve comments.
2320 * valprint.c (type_print_varspec_suffix): Print array size only
2321 if greater than zero.
2322 * m88k-tdep.c: Shift some lines left by one space, that had
2323 apparently been trashed at some point.
2324 * TODO: More things to do, a few got done.
2326 Thu Jul 18 22:46:05 1991 John Gilmore (gnu at cygint.cygnus.com)
2328 * symtab.h (LOC_EXTERNAL): Eliminate in favor of LOC_STATIC.
2329 (ldsymoff, ldsymlen, globals_offset, statics_offset): Improve
2331 * dbxread.c (read_dbx_symtab): LOC_EXTERNAL -> LOC_STATIC.
2332 * expread.y, findvar.c, symmisc.c: Ditto.
2333 * printcmd.c (address_info): Update printed forms of LOC_
2334 symbols. Elim LOC_EXTERNAL.
2335 (print_frame_args): Keep track of param stack offsets before
2336 re-looking up to find the local register param is kept in.
2338 * mipsread.c: Use <symconst.h> and <sym.h> rather than <syms.h>.
2339 Further integration of mipsread into gdb. Eliminate unused
2340 routines, duplicate declarations. Handle static symbols in
2341 psymtabs as well as external symbols. When reading symtabs,
2342 insert symbols into the correct block (global, static, or a local
2344 (read_mips_symtab, parse_partial_symbols): Don't pass useless
2346 (mipscoff_symfile_read): Don't call select_source_symtab.
2347 (parse_symbol): Use SYMBOL_VALUE_ADDRESS where appropriate,
2348 rather than SYMBOL_VALUE.
2349 (parse_external): Comment clobbering of top_stack.
2350 (parse_partial_symbols): Update comments. Allocate and parse
2351 static symbols as well as external symbols. FIXME, enum values
2352 are not handled in this pass, but should be. Inline new_psymbol.
2353 Use SYMBOL_VALUE_ADDRESS.
2354 (psymtab_to_symtab_1): Read symbols into global static block
2355 by default (until enter some function's local block context).
2356 (sort_blocks): Clean up STATIC_BLOCK as well as GLOBAL_BLOCK.
2357 (destroy_all_symtabs, new_psymbol): Eliminate, unused.
2359 * source.c (select_source_symtab): Select a source symtab
2360 from either the symtabs or, failing that, the psymtabs.
2361 (list_command): Update error message.
2362 (forward_search_command, reverse_search_command): Use getc, not
2363 fgetc, for speed. FIXME, add comment about buffers that die if
2364 overrun by long line.
2366 * values.c (unpack_field_as_long, modify_field): Avoid shifting
2367 by an entire word, which is not portable, if we have a 32-bit
2368 field. (Code in dbxread.c already turns such bitfields, if
2369 aligned, into ordinary ints, but fixing this will help for other
2370 symbol formats and for future changes.)
2371 * core.c (core_open): Handle ANSI const brain death.
2372 * utils.c (vprintf): Fix varargs typo.
2374 Sun Jul 14 00:42:53 1991 John Gilmore (gnu at cygint.cygnus.com)
2376 * findvar.c (find_var_value): Handle &function better.
2377 * TODO: Document work needed on &fn and &array.
2378 * printcmd.c (print_address_symbolic): New arg is the prefix
2379 to print if a name is printed.
2380 (print_address_demangle): Honor "set print address" now.
2381 Use new arg above to improve spacing of output.
2382 * valprint.c (val_print): When printing function pointers,
2383 print symbolic form too.
2384 * breakpoint.c (breakpoint_1): Use new print_address_symbolic.
2386 Mon Jul 8 19:02:46 1991 John Gilmore (gnu at cygint.cygnus.com)
2388 * core.c (memory_error): Reword error msg to mislead less.
2390 * mips-pinsn.c (print_insn_arg 'd'): Print $ with reg name.
2392 * mipsread.c (read_mips_symtab, read_the_mips_symtab,
2393 parse_partial_symbols): Use newer BFD internals (external_filehdr
2394 and external_aouthdr), byte-swap the fields that we care about
2395 before using them, and make the file header data local to
2396 read_the_mips_symtab rather than global.
2398 Sat Jul 6 01:34:15 1991 John Gilmore (gnu at cygint.cygnus.com)
2400 * ns32k-opcode.h (movmw, movmd): Fix opcodes. Bug fix
2401 from Rune Nerg}rd <runene@ifi.uio.no> on 5 Jul 1991.
2403 * main.c (command_line_input): Flush stdout and stderr
2404 before every call to readline. This reportedly fixes a bug
2405 that comes up in Sys V running emacs-gdb and/or xxgdb,
2406 when stdin/out are pipes or sockets.
2408 Thu Jul 4 14:47:06 1991 John Gilmore (gnu at cygint.cygnus.com)
2410 * configure.in, Makefile.in: Avoid rebuilding "depend" as much.
2411 Avoid declaring Makefile dependencies, because GNU Make stupidly
2412 tries to update it if we do.
2414 * coffread.c: Revise for minor changes to bfd internal coff
2417 * configure: If -template= is given a relative path, make it
2418 absolute before recurring in subdirectories.
2420 * configure, configure.in, Makefile.in: Install "configure" script
2421 as replacement for config.gdb.
2422 * config.gdb, Makefile.dist, Makefile.sdir: Remove
2423 * README: Update for configure, mostly. FIXME.
2425 * Add dec3100 as equivalent to littlemips. Indicate in all host &
2426 target config files that they are for the host. When the lines
2427 get copied into the Makefile, this makes it more obvious what's
2430 Mon Jun 24 23:49:07 1991 John Gilmore (gnu at cygint.cygnus.com)
2432 * sparc-opcode.h (trap opcodes): Avoid leading spaces or
2433 tabs, which end up in the disassembler output inadvertently.
2435 Wed May 29 23:01:03 1991 John Gilmore (gnu at cygint.cygnus.com)
2437 Make it compile cleanly in an ANSI GCC2 environment.
2439 * blockframe.c: <stdio.h>
2440 * cplus-dem.c: free takes a void *, ifdef __STDC__
2441 * dbxread.c (read_huge_number): avoid gcc2 bug hoisting calc of
2443 * defs.h (alloca): Avoid doing anything if alloca already def'd.
2444 * stddef.h, stdlib.h: Remove these files.
2445 * symtab.c: Avoid declaring qsort, close.
2446 * symfile.c: Avoid declaring close.
2447 * utils.c (vprintf): Declare "ap" arg as proper va_alist.
2448 * sparc-tdep.c: Avoid including lots of Sun-host-specific files.
2450 Assorted other changes.
2451 * dbxread.c: include "libaout.h", not "liba.out.h".
2452 * printcmd.c (print_frame_args): Set recurse properly for
2453 indentation of struct and array parameters.
2454 * valops.c (value_cast): Allow cast to void.
2455 * infrun.c (resume): If NO_SINGLE_STEP, call machine dependent
2456 single_step() in a target-independent fashion.
2457 * sparc-tdep.c (single_step): Don't call ptrace ourselves, just
2458 set up to be ready to continue. This makes us target independent.
2459 * infptrace.c (child_resume): Remove call to single_step; now
2460 can single step a SPARC target of any kind.
2462 Wed May 22 18:18:24 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
2464 * Makefile.dist, doc/gdb.texinfo, doc/*-m4.texinfo: split up GDB
2465 docn into separate sections---basically chapters, plus two loose
2466 pieces that can be configured to go in different places. This
2467 allows GNU m4 to preprocess the manual without coredumping.
2469 * Makefile.dist: tell TeX where to find texinfo.
2471 Mon May 20 12:15:04 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
2473 * Makefile.dist, doc/gdb.texinfo: respectively create, and use,
2474 the new target "rdl-apps.texinfo" which captures the Makefile
2475 variable that records where to find the Readline libraries.
2477 Sun May 19 05:36:59 1991 John Gilmore (gnu at cygint.cygnus.com)
2479 * tahoe-pinsn.c: #include "tahoe-opcode.h", not "opcode.h".

2481 * defs.h (const, volatile): Only define if not already defined.
2482 * Makefile.dist (gdb.tar.Z): Create doc subdir w/out CVS/RCS crud.
2484 * README: Update for release 3.95.
2485 * config.gdb: Don't create readline dir in subdir builds.
2486 * main.c: Include with "..." form for non-system include files,
2487 so "gcc -MM" for "make depend" works.
2488 Include readline files with "...h" rather than <readline/...h>.
2489 * mipsread.c: Include "ecoff.h" rather than "intel-coff.h".
2491 * coffread.c: Undo minor damage done by Rich Pixley. Use
2492 different internal and external representations of COFF
2493 data structures. Use new BFD routines for swapping them in and
2495 * symfile.c (free_named_symtabs): Avoid freeing file names that
2496 are null or empty. Old i960 tools seem to produce files that
2497 claim to have empty names, causing each successive file read
2498 to blow away the previous one.
2499 * sparc-xdep.c (deferred_stores): Repair minor damage by Rich.
2500 Move deferred_stores to top of file, but don't separate its
2501 #define's from its variable. Add commentary.
2502 * Makefile.dist: Fix Rich damage; undo "configure" changes in
2503 favor of keeping the (working) config.gdb. Move readline
2506 Fri May 17 12:49:56 1991 Per Bothner (via gnu at cygint.cygnus.com)
2508 * dbxread.c (read_struct_type): Try to handle g++ version 1 MI
2510 * infptrace.c (fetch_registers): no result, since now void.
2511 * tconfig/news: target depends on m68k-tdep too.
2513 Fri May 17 14:40:14 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
2515 * Makefile.dist: added readline/inc-*.texinfo to dependencies for
2518 * readline/inc-history.texinfo, readline/inc-readline.texinfo:
2519 applied various small fixes due to or inspired by RMS comments
2521 * doc/gdb.texinfo: finished using all RMS comments, save those for
2522 appendices on readline and cmd history (which are in other source
2525 Thu May 16 18:06:05 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
2527 * doc/gdb.texinfo: (1) Updated w/ref to RMS comments through
2528 chapter 9; (2) documented 'break' command's menu mode for
2529 overloaded names, in response to hgs problem report C++ p-31
2531 Wed May 15 11:02:48 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
2533 * doc/gdb.texinfo: (1) better introductory example; (2) more
2534 consistent use of @code, @samp, @file, @kbd throughout; small
2535 cleanups to first three nodes; (3) new "Contributors" node;
2536 (4) Appendix, Renamed Commands; (5) divert specialized startup
2537 instructions to "Targets" chapter for generic manuals, while
2538 leaving them up front for manuals specific to specialized
2539 environments; (6) apply fixes from RMS comments through chapter 4.
2541 * pretex.m4: modify explanatory text slightly (and redefine
2542 "regexp") to keep GNU m4 from complaining. (It still crashes
2543 later, but one step at a time...)
2545 Wed May 15 10:32:12 1991 John Gilmore (gnu at cygint.cygnus.com)
2547 * readline/readline.c (update_line): Avoid dereferencing a pointer
2548 before comparing it to its bounds. Saber caught this.
2549 (init_terminal_io): Don't set BC from the "pc=" termcap variable,
2550 and only set PC if tgetstr returned non-null. Saber caught this.
2552 Tue May 14 16:29:53 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)
2554 * Makefile.dist: put gdb.dvi stuff (updated to use M4 preprocessor
2555 stuff for config manual) here where it counts; updated
2556 to use new subdir structure (gdb/doc/).
2558 * Makefile: generated from above via
2562 * gdbint.texinfo: added instructions on generating gdb.info* files
2563 locally for release. These are ordinary info
2564 files, formatted from gdb.texinfo (via gdb-all.texinfo, see
2565 Makefile)---but due to use of texinfo 2, can't count on makeinfo
2566 to generate these, so we distribute them already formatted.
2568 * gdb.texinfo: included full Info node and menu crud (as generated
2569 by C-u M-x texinfo-master-menu using the texinfo-2 elisp code).
2571 * Makefile: updated "gdb.dvi" target to use M4 preprocessor;
2572 put in comments-for-future gdb.info target (one day makeinfo will
2575 Tue May 14 13:51:36 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)
2577 * gdb.texinfo: Updated to include new or old undocumented
2578 commands, at least the following (perhaps some others I forgot to
2579 record): info f, info float, info path, info program, info s, info
2580 set, info source, info terminal, info types, info user, set/show
2582 Also covered all recent GDB command renames for v4.
2584 Mon May 13 14:57:46 1991 John Gilmore (gnu at cygint.cygnus.com)
2586 * mipsread.c: Rather than keeping count of how many symtabs
2587 and psymtabs we have, for sorting purposes, count them when
2588 we need to sort. This fixes bug in rereading of symbol tables.
2590 Fri May 10 15:43:33 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)
2592 * infcmd.c: renamed "info path" to "show paths"

2607 symtab.h, target.c, target.h: Lint.
2608 * core.c: setup and select frame after reading shared libs,
2609 else reading shared libs will clobber them. Lint.
2610 * utils.c (error): Force out any buffered wrap text.
2612 Fri May 3 22:01:56 1991 John Gilmore (gnu at cygint.cygnus.com)
2614 * remote.c: Remove decls of memory_insert_breakpoint
2615 and memory_remove_breakpoint, no longer used. (Suggestion of
2618 * Makefile.dist: use ${subdir} in paths of BFD and LIBIBERTY,
2619 to make it easier to interface to "configure"'d libraries.
2621 Fri May 3 13:10:01 PDT 1991 Roland Pesch (pesch at fowanton.cygnus.com)
2623 * valprint.c: introduce "set p", "set pr", "show p" and "show pr" as
2624 aliases for set/show print.

3173 been read in, particularly for VxWorks.
3175 * dbxread.c (read_dbx_symtab): Allow N_SOL to cleanly take us back
3176 to the main file, as well as to include files. Also, put global
3177 functions into the global psymtab, to make "i fun" work.
3178 (end_psymtab): Free named symtabs and psymtabs for a file, once a
3179 new psymtab for it has been read.
3180 * coffread.c (end_psymtab): Free named symtabs and psymtabs for
3181 a file, once a new symtab has been read for it.
3182 * mipsread.c: FIXME. We need to do the same for MIPS, but it
3183 looks harder to determine the top-level block before it's been
3184 queued to the psymtab list.
3186 * symfile.c (symbol_file_add): Use filtered printing and wrap it.
3187 If we have wiped out any old symbol tables, clean up at end of
3189 (symbol_file_command): Don't reference symfile_fns if it's zero.
3191 * symtab.h (GLOBAL_BLOCK, STATIC_BLOCK, FIRST_LOCAL_BLOCK): New
3192 defines for the blocks of a blockvector that contain global and
3193 file-static symbols and the first of the smaller scope contours.

3202 * symtab.c (list_symbols): Process the first symbol of the
3203 static psymbols list.
3204 (types_info): Restore this function from its untimely #if 0.
3205 It's not perfect, but it is better than nothing.
3206 (_initialize_symtab): Restore "info types".

3210 * m68k-stub.c: Remote stub for 680x0's, created from
3211 rem-m68k.shar (which is removed).

3217 * symmisc.c (free_named_symtab): Make it work, in its current
3218 kludgy fashion. Change result to indicate if we blew away bkpts.

3220 free_named_symtab and print warning if we blew user's state.
3221 * symfile.h: free_named_symtab now returns an int.
3223 Mon Apr 8 23:57:43 1991 John Gilmore (gnu at cygint.cygnus.com)
3225 * dbxread.c (dbx_symfile_read): Initialize psymbol list if this
3226 is the first symbol read, even if not mainline.
3227 (dbx_psymtab_to_symtab): symfile might be zero, cope.
3228 * exec.c (exec_ops): Add_syms_addr is valid in our tvec.
3229 (set_section_command): New command ("section xxx yyy" -- should
3230 be renamed to "set section xxx yyy" FIXME) which sets the
3231 base address of a section of the exec file, overriding the
3232 virtual address that BFD reports.
3234 Fri Apr 5 17:14:39 1991 John Gilmore (gnu at cygint.cygnus.com)
3236 * exec.c: Add add_syms_addr_command to exec_ops, so you can
3237 load symbols at any address while examining an exec file.
3239 Thu Apr 4 10:09:35 1991 John Gilmore (gnu at cygint.cygnus.com)
3241 * tm-i386v.h (FLOAT_INFO): Don't define it, since the code
3242 for printing the float info is host-dependent, not
3243 target-dependent. FIXME.
3244 * i386-pinsn.c: Move #includes to top, remove useless ones.
3245 * i386-tdep.c: Don't bother including <.../reg.h> since we
3246 don't use it (and it doesn't exist on host systems).
3248 * ieee-float.c (ieee_extended_to_double): Convert NaN to Inf.
3249 Convert negative numbers properly.
3250 (ieee_test): Make numbers really random; fix format arg.
3252 * infcmd.c (attach_command, detach_command): Don't repeat on CR.
3253 * core.c (core_detach): Unpush core_ops, which might not be on
3254 top. We used to just pop the top, which broke things. Don't
3255 need dont_repeat() any more.
3256 (core_file_command): Psst! Don't repeat it.
3257 * remote-nindy.c (nindy_detach): Don't need dont_repeat() now.
3258 * expprint.c (print_subexp): Avoid switch fallthru on
3259 BINOP_ASSIGN_MODIFY, so we can print += and such.
3260 * frame.h: Fix typo.
3261 * inflow.c (kill_command): After killing inferior, print our
3262 current frame in the core file, if we have one.
3263 (generic_mourn_inferior): When inferior dies, either select
3264 the current frame (in the new target, e.g. core file), or
3265 set both the current and selected frames to NULL.
3267 Changes from Peter Schauer.
3269 * infptrace.c: Avoid <sys/ptrace.h> on USG.
3271 * Make all file names fit in 14 characters (sigh and damn!):
3272 mv hp300hpux-xdep.c hp300ux-xdep.c
3273 mv symmetry-xdep.c symm-xdep.c
3274 mv symmetry-tdep.c symm-tdep.c
3275 mv convex-opcode.h convx-opcode.h
3276 mv tm-vxworks960.h tm-vx960.h
3277 mv tm-vxworks68.h tm-vx68.h
3278 mv Makefile.srcdir Makefile.sdir
3279 mv gdb-int.texinfo gdbint.texinfo
3280 mv remote-sa.m68k.shar rem-m68k.shar
3281 mv remote-multi.shar rem-multi.shar
3282 * Makefile.dist, README, config.gdb, convex-pinsn.c,
3283 tconfig/symmetry, tconfig/vxworks960, tconfig/vxworks68,
3284 xconfig/hp300hpux, xconfig/symmetry: Change names to shorter
3287 * command.c (user_info_1, user_info): New command for listing
3288 the user-defined commands.
3290 Wed Apr 3 15:00:26 1991 John Gilmore (gnu at cygint.cygnus.com)
3292 * dbxread.c (really_free_pendings): Clear file_symbols
3293 and global_symbols after freeing them; otherwise, running
3294 this function twice (if it appears twice on the cleanup
3295 chain), we try to free things twice.
3297 * dbxread.c (read_dbx_symtab): Calculate end_of_text_addr
3298 based on text_addr (the address of text in core), not on addr (the
3299 offset between text in the .o file and in core). This change
3300 is from Peter Schauer.
3302 * main.c: Define ALL_CLEANUPS as a cast of zero.
3303 (return_to_top_level): Use it.
3304 (main): Do all cleanups after each command run as part
3305 of the gdb startup sequence. Also do all cleanups before
3306 entering the command loop, and every time we exit the command
3307 loop and reenter. Before, the cleanups from the startup sequence
3308 were being left undone until the first error!
3309 (command_loop): Rename do_nothing cleanup to command_loop_marker
3310 so we can see it easily when examining the cleanup chain.
3311 (init_signals): Add another do_nothing for signal handling.
3312 (quit_command): Only try to kill target if it has execution.
3313 Problems in the target stack got us into a state where
3314 inferior_pid was nonzero but none of the targets had execution.
3315 In this state you couldn't exit gdb.
3317 * dbxread.c: Two changes from Peter Schauer.
3318 (echo_command): Fflush output after an echo command.
3319 (show_history): Pass all args to cmd_show_list.
3321 * utils.c (init_malloc): Call mtrace to turn on tracing
3322 if the environment variable MALLOC_TRACE is set to a file name.
3323 * mtrace.c: Add source file which provides a log of every malloc,
3324 free, and realloc to a trace file.
3325 * mtrace.awk: Add source file which analyzes the trace file.
3326 * Makefile.dist (GNU_MALLOC, MALLOCSRC): Add mtrace.{c,o,awk}.
3327 (VERSION): Roll to 3.94.3.
3329 * breakpoint.c (breakpoint_1): Add a space to "i watch" output.
3330 (check_duplicates): Don't bother with watchpoints.
3331 (set_raw_breakpoint): Comment about danger of this routine.
3332 (watch_command): Parse and eval all args before calling
3335 * solib.c (find_solib): Avoid error in referencing memory to
3336 see if any more shared libraries have been added. This is
3337 particularly useful if the target has terminated. Bug reported
3340 Changes from Peter Schauer <pesrem@regent.e-technik.tu-muenchen.de>
3341 in bringing up 3.94.2 on the Sun-3.
3343 * Makefile.dist: Include CFLAGS in rule for cplus-dem.o.
3344 * breakpoint.c (enable_breakpoint): Check for valid watchpoint
3345 expression (in scope) before reenabling watchpoint.
3346 * signame.c (init_sigs): Add missing declaration of i, fix
3347 sys_siglist declaration.
3348 * source.c (list_command): Fixed range computation to use
3350 * stack.c (backtrace_command): Do not allow command if target has
3351 no stack, print informative error message.
3352 * target.c (target_command): Do not write into command line
3353 because this fails if the target command is used in a user defined
3354 command. [This change was enhanced by gnu to support any-
3355 unique-prefix matching on target names.]
3356 * valops.c (value_struct_elt): Avoid infinite loop on an
3357 erroneous attempt to print the member of function (try p main.p).
3359 Mon Apr 1 17:05:45 1991 John Gilmore (gnu at cygint.cygnus.com)
3361 * expread.y (name_no_typename): Avoid reduce/reduce errors
3362 caused by ambiguity in handling NAME_OR_INT and NAME_OR_UINT.
3363 Since the GDB parser really doesn't use name_no_typename in a
3364 name-only context, the parser can't tell the diff between
3365 names and numbers here. Avoid allowing a name_no_typename
3366 to be a NAME_OR_*INT to resolve the conflict.
3368 Sun Mar 31 20:12:07 1991 John Gilmore (gnu at cygint.cygnus.com)
3370 Bugfixes from Mark Fox (markf@wrs.com) (test=testField.c):
3372 * valprint.c (val_print_fields): bitfield printing didn't handle
3373 byte order. Indirect through a few more fns to cope.
3375 * values.c (modify_field): also cope with byte order.
3377 Sat Mar 23 10:02:21 1991 John Gilmore (gnu at cygint.cygnus.com)
3379 Cleanup for release 3.94.2:
3381 * Makefile.dist: Pull REMOTE_OBS. Fix saber includes for BFD
3382 include files. Roll version to 3.94.2.
3384 * coffread.c (init_stringtab): Read length into unsigned char
3385 array before swapping; don't assume 32-bit longs.
3387 * target.c (target_info): Don't bother with get_sym_file, just use
3388 the symfile global variable.
3389 * symtab.h, symfile.c (get_sym_file): Delete it.
3391 * dbxread.c (dbx_symfile_init): Don't depend on long == 4 bytes.
3392 (define_symbol): Set symbol line number to 0 if not gcc-compiled.
3393 (read_type): Replace one more error() with complain().
3395 * mipsread.c (parse_partial_symbols): Replace printf with complain.
3397 * i960-tdep.c: Fix copyright attribution.
3399 * config.gdb: Quote all backquotes in doublequotes. You can
3400 quote me on that. BSD 4.4 shell found this one.
3402 * infptrace.c (throughout): The third argument to ptrace is an
3405 * infrun.c (wait_for_inferior): When program has terminated, we
3406 have to call target_terminal_ours before we pop that target off
3407 the stack (e.g. before a call to target_kill or
3408 target_mourn_inferior). This fixes problem where a program
3409 terminates, then GDB stops for (tty output) and you have to type
3410 "fg" to the shell to resume it. FIXME: This code for what to
3411 do after termination really should be in normal_stop instead.
3413 * gdbcore.h (read_memory_check): Change declaration; it changed
3416 * terminal.h: Include <sgtty.h> before <sys/ioctl.h>, since in BSD
3417 4.4 prereleases, this avoids a bug in their sgtty compatability
3419 * remote.c: Use terminal.h rather than hand-rolling the same.
3421 * signame.c, signame.h (psignal): Arg is unsigned, not int.
3422 * utils.c (strsave, strstr): Fix arg types.
3423 * valprint.c (val_print): lint
3425 MIPS symbol table support from Per Bothner:
3427 * symfile.c (symtab_fns): Remove initializer table that needs to
3428 be hacked for each new symbol file format supported.
3429 (add_symtab_fns): New function, chains symbol table
3430 handlers into the global list.
3431 (symfile_init): Search this list.
3432 * symfile.h: Add next pointer, declare add_symtab_fns.
3433 * coffread.c (_initialize_coffread): Call add_symtab_fns.
3434 * dbxread.c (_initialize_dbxread): Call add_symtab_fns.
3436 * mipsread.c (psymtab_to_symtab_1): return void instead of (struct
3437 symbol *). Thus, we no longer need the hack to trash
3438 pst->filename. Good, since that hack confused code in symfile.c!
3440 (reorder_symtabs, destroy_all_symtabs): Removed static
3441 all_symtabs, which was used to qsort symtabs in reorder_symtabs.
3442 Instead, the latter now uses a temporary array (stack-allocated
3443 from an obstack, and then freed).
3445 (parse_symbol): Added a hack to fix up BLOCK_{START,END} if they
3446 haven't been set in the outermost stBlock of a procedure. This was
3447 a problem with f77 binaries on Ultrix 4.?.
3449 (new_symtab, new_symbol, new_type): Continue changing code to use
3450 obstacks more and otherwise conform to dbxread internal style.
3451 Made the free_code of symtabs be free_linetable (as in dbxread)
3452 instead of free_contents. This implies memory leaks when reading
3453 a new symbol table, until the conversion is finished. Did change
3454 (struct symbol) and (struct type) to be allocated on the
3455 symbol_obstack. Blocks and blockvectors are among the things
3458 * mipsread.c (parse_partial_symbols, parse_fdr): It hasn't been
3459 tested much, but it solved one problem (reported by Meissner), and
3460 cleans up some other things. The problem happened when an
3461 included file contains actual code (functions) and not just
3462 definitions. The mips coff is a little inconvenient there, since
3463 it may cause a procedure to be mapped to the wrong psymtab.
3465 * mips-tdep.c (heuristic_proc_desc): Minor cleanup.
3466 * mips-xdep.c (fetch_core_registers): Minor cleanup. FIXME,
3467 this will need work for the new core paradigm.
3469 Opcode patches from the net:
3471 * mips-opcode.h: fix incorrect disassembly of the mfc1, cfc1, and
3472 ctc1 instructions. Also, the cvt.d.w and cvt.s.w instructions were
3473 missing altogether - they are added here. From Bruce Bauman.
3474 * mips-opcode.h: The low mask for C0 instructions was too small.
3475 From Garrett Lau. I modified the fix to check the entire 32-bit
3478 * ns32k-opcode.h: Fix opcodes for deiw and deid. From Bruce
3481 Thu Mar 21 12:56:46 1991 John Gilmore (gnu at cygint.cygnus.com)
3483 Roll in changes from Per Bothner (Tue, 25 Sep 90 11:11:04):
3485 * dbxread.c (read_type): Pointer subtraction (value_sub in
3486 valarith.c) sometimes failed because the types of the
3487 pointers being subtracted were not identical.
3488 These differed because dbxread.c was allocating pointer types
3489 using dbx_alloc_type+smash_to_pointer_type instead of
3490 lookup_pointer_type. I failed to find a justification for the
3491 former, so I changed it to use the latter. Similarly, I
3492 replaced smash_to_function_type by lookup_function_type,
3493 and smash_to_reference_type by lookup_reference_type.
3495 * mipsread.c (parse_symbol, upgrade_type, parse_procedure,
3496 _initialize_mipsread): corresponding changes.
3498 * symtab.c (smash_to_{pointer,reference,function}_type): eliminate.
3500 * source.c (mod_path): Do tilde_expand on each component of the path,
3501 rather than on the (list of) paths as a whole.
3502 (print_source_lines): Set first_line_listed in addition to
3503 current_source_symtab and current_source_line. If the source was
3504 not findable, after a "dir" command to fix the problem,
3505 a "list" would get the wrong lines.
3507 While I was there... (gnu):
3509 * dbxread.c (read_type): Change error to complaint.
3511 Thu Mar 21 12:56:46 1991 John Gilmore (gnu at cygint.cygnus.com)
3513 First attempt at detailed understanding of symbol table memory alloc.
3515 * dbxread.c (dbx_symfile_read): Free our string table if we
3516 aren't the mainline. Free the "info" struct since we're done with
3518 (init_psymbol_list): Free any previously allocated psymbol lists.
3519 (): FIXME: Should realloc-down the psymbol lists when done reading
3520 the main symbol file?
3522 * symmisc.c (free_symtab): Free fullname field too.
3524 * xm-hp300hpux.h (USG): #undef then #define so Makefile can -D.
3525 (REGISTER_ADDR): Make result type unsigned int.
3527 * xconfig/{i386*,hp300hpux,altosgas,altos}: All config files that
3528 define REGEX must also define REGEX1 (its dependency).
3530 Tue Mar 19 21:28:57 1991 John Gilmore (gnu at cygint.cygnus.com)
3532 * tconfig/i960: No longer works, points you at vxworks960 or
3535 * xgdb.c, XGDB-README: Remove file. Users can get the much
3537 * Makefile.dist: Remove all trace of xgdb.
3539 * breakpoint.c (breakpoint_1): Pass demangle arg to
3540 print_address_symbolic.
3541 (clear_breakpoints): Remove unused function.
3542 (breakpoint_re_set_one): Guts of breakpoint_re_set.
3543 (breakpoint_re_set): Use catch_errors to do them all anyway.
3545 * gdb-int.texinfo (Host versus Target): Add section on what is
3546 a "host" feature versus what is a "target" feature.
3548 * infcmd.c (path_command, path_info): Handle the PATH variable
3549 (object search path) as conveniently as the source search path.
3550 * environ.c (set_in_environ): Set some vars in GDB's environment,
3551 in addition to the child's. PATH, G960BASE, G960BIN for starters.
3552 * source.c (mod_path): New function, from guts of
3553 directory_command, modifies a path. Used by path_command.
3554 (directory_command): Call it.
3555 * defs.h (strsave): Declare.
3557 * utils.c (sevenbit_strings): Add new printing option.
3558 (printchar): Use it.
3559 (strsave): Provide this handy helper routine.
3560 (set_width_command): Rename set_screen_width_command.
3561 (_initialize_utils): "set screen-width" => "set width";
3562 "set screen-height" => "set height"; add sevenbit-strings.
3564 * infcmd.c (do_registers_info): Print floating point registers
3565 in raw hex as well as float format, regardless of whether it is
3566 a "virtual" convertible register.
3567 * tm-sparc.h (PRINT_REGISTER_HOOK): Print every pair of float
3568 regs as a double, just in case it's being used that way.
3569 * values.c (unpack_long): Comment on array/function coercion.
3570 (unpack_double): Argument is in target byte order now. For
3571 integer arguments, just call unpack_long and float the result.
3572 * m68k-tdep.c: include defs.h for "const" handling.
3573 * remote-nindy.c: Use ieee-float stuff.
3574 (nindy_fetch_registers): Unpack double regs to host double, then
3576 (nindy_store_registers): Pack extendeds to host double, flip
3577 around by misusing unpack_double, send as target double.
3579 * tm-vxworks68.h (FRAME_CHAIN): Handle current frame pointer of
3580 zero, as when stopped at the first instruction of a process.
3582 * blockframe.c: Fix filename in comment (param.h => tm.h).
3583 * sparc-tdep.c (skip_prologue): More explicit nudging comments.
3584 * tm-68k.h: Fix typos.
3586 Fri Mar 15 01:09:34 1991 John Gilmore (gnu at cygint.cygnus.com)
3588 Changes from a bringup on the DEC Vax under Ultrix 4.0.
3590 * coredep.c (fetch_core_registers): Pass end-address of register
3591 section to register_addr as expected. Don't call supply_register
3592 if we'd just pass it garbage.
3594 * dbxread.c (read_dbx_symtab): Skip N_NSYMS on Ultrix.
3596 * exec.c (xfer_memory): Use boolean xfer_fn result, not int.
3598 * target.c (push_target, target_info): Cast enums to int for < or
3601 * stack.c (print_frame_info): Identify source file & line
3602 even if we can't print it.
3604 * xm-vax.h (MISSING_VPRINTF): No longer missing in Ultrix V4.0.
3606 Sat Mar 9 10:08:20 1991 John Gilmore (gnu at cygint.cygnus.com)
3608 Clean up IEEE floating point support.
3610 * ieee-float.h: New file.
3611 * ieee-float.c: Write real routines to convert between host
3612 doubles and various target IEEE extendeds.
3613 * m68k-xdep.c: Eliminate assembler code for extended floats.
3614 * xconfig/{3b1,altos,altosgas,hp300bsd,isi,news,news1000,sun2os3,
3615 sun2os4,sun3,sun3os3,sun3os4}: Eliminate use of m68k-xdep.o.
3616 * tm-i960.h, tm-68k.h (REGISTER_CONVERT_TO_VIRTUAL,
3617 REGISTER_CONVERT_TO_RAW): Use ieee_extended_to_double and
3618 double_to_ieee_extended.
3619 * i960-tdep.c: Define ext_format_i960.
3620 * m68k-tdep.c: Define ext_format_68881.
3621 * sparc-tdep.c: Define ext_format_sparc, though unused.
3622 * Makefile.dist (HFILES): Add ieee-float.h.
3623 * inftarg.c: #include "ieee-float.h" for the REGISTER_CONVERT
3626 Obsolete the "coffstrip" program in favor of using BFD's strip.
3628 * nindy-share/coffstrip.c: Remove file.
3629 * nindy-share/nindy.c (coffstrip): Routine to run bfd_strip.
3630 * Makefile.dist: Remove references to nindy-share/coffstrip.c.
3631 * tconfig/nindy960: Remove reference to coffstrip.o.
3633 * Makefile.dist: Roll version number to 3.94.1 (not yet final).
3635 Wed Mar 6 09:56:45 1991 John Gilmore (gnu at cygint.cygnus.com)
3637 * symfile.h: Add symfile_bfd, common between dbxread and coffread.
3638 * dbxread.c: Remove static symfile_bfd.
3639 * infcmd.c (do_registers_info): Add PRINT_REGISTER_HOOK, though
3641 * inftarg.c (child_detach): Pop the child_ops vector if the
3642 detach is successful.
3643 * remote-nindy.c (nindy_create_inferior): Don't push a new
3644 nindy_ops since nindy uses the same one for execution and memory
3646 * core.c (core_ops): Use child_attach and child_create_inferior
3647 rather than default attach and create_inferior functions.
3649 Handle floating point registers in core files.
3651 * sparc-xdep.c (fetch_core_registers): Rewrite for float support.
3652 * sun3-xdep.c (fetch_core_registers): Rewrite for float support.
3653 This version untested since BFD doesn't yet support sun3 core
3655 * hp300hpux-xdep.c: Rewrite fetch_core_registers to new calling
3656 conventions. Fix comments and style. This version has not
3657 been compiled yet, since we have no HP inhouse.
3658 * core.c (get_core_registers): Look for two sections, ".reg"
3659 and ".reg2", and pass both to fetch_core_registers sequentially.
3661 Revise directory path yet again.
3663 * source.c (forget_cached_source_info): Not static any more.
3664 (init_source_path): New default source path is "$cdir:$cwd".
3665 (dir_command): Handle variable arguments ($cdir, $cwd).
3666 (source_info): Print "Compilation directory" rather than
3667 "Originally compiled in" to remind people of $cdir.
3668 (openp): If the path contains $cwd, use current directory.
3669 (open_source_file): If compilation directory is known, replace
3670 first $cdir in path with the compilation directory.
3671 (print_source_lines): Even if we can't print the lines, set the
3672 current symtab and line for future commands like "info source" or
3673 "breakpoint". Also, error message now contains the file name,
3674 line number, and file access error message.
3675 (_initialize_source): Fix help text to describe changes.
3676 * main.c (cd_command): Forget cached source info when we chdir.
3677 * utils.c (strstr): Add simple implementation.
3679 Tue Mar 5 01:41:40 1991 John Gilmore (gnu at fowanton.cygnus.com)
3681 * coffread.c (read_one_sym, init_linetable, init_stringtab):
3682 Byte-swap COFF symbol tables if necessary when reading them in.
3683 Use complain() to replace error message in one spot. Needs
3684 corresponding change in bfd/coff-code.h to make some symbol
3685 swapping routines non-static.
3687 Mon Mar 4 00:53:40 1991 John Gilmore (gnu at cygint.cygnus.com)
3689 Merge changes from Eirik Fuller, for UTek.
3691 * defs.h (errno): Add declaration.
3692 * altos-xdep.c, arm-xdep.c, convex-xdep.c, gould-xdep.c,
3693 hp300hpux-xdep.c, infrun.c, inflow.c, infptrace.c, i386-tdep.c,
3694 i386-xdep.c, pyr-xdep.c, mips-xdep.c, remote-eb.c, remote-nindy.c,
3695 remote-vx.c, source.c, standalone.c, stuff.c, sun386-xdep.c,
3696 symmetry-tdep.c, symmetry-xdep.c, umax-xdep.c, utils.c: Eliminate
3697 declarations of errno.
3699 * remote-eb.c: Define B19200 and B38400 as EXTA and EXTB.
3701 * remote-vx.c: Include <sys/time.h> for UTek; Sun gets it via
3702 <rpc/rpc.h> and <rpc/types.h>.
3704 Sat Mar 2 15:47:55 1991 John Gilmore (gnu at cygint.cygnus.com)
3706 * i960-tdep.c (examine_prologue): Add new argument limit,
3707 which stops the scan at the end of the prologue, or at the PC.
3708 This fixes a problem where it walks down into the code for the
3709 user's statements if that code looks like function prologues.
3710 Mark Fox and I have been bouncing this code back and forth, making
3711 small changes to it. Callers changed to match.
3713 Tue Feb 26 01:47:07 1991 Cygnus John Gilmore (cygnus at yuba)
3715 Cleanup for gdb-3.94 release final:
3717 * Makefile.dist: Remove remote-vx.c, remote-nindy.c, and all
3718 the .c files from vx-share and nindy-share, from the various
3719 macros, since they are not found via ALLDEPFILES.
3720 (SFILES): Add tm-i960.h.
3721 (alldeps.mak rule): Break out ALLDEPFILES_MAINDIR and
3722 ALLDEPFILES_SUBDIR. List all the nindy and vxworks subdir files
3724 (TAGFILES_MAINDIR): Change ALLDEPFILES to ALLDEPFILES_MAINDIR.
3725 (gdb.tar.Z): Use ALLDEPFILES_SUBDIR as well as SFILES_SUBDIR.
3727 Mon Feb 25 16:02:35 1991 Cygnus John Gilmore (cygnus at oldman)
3729 * am29k-tdep.c: Add contribution line.
3730 (examine_prologue): Cache information about function prologues in
3731 the misc-function-vector to avoid lots of references over the
3732 serial line while examining instructions.
3734 * core.c (core_close): New function made from cleanup_core.
3736 * core.c, exec.c, inftarg.c, remote-eb.c, remote-nindy.c,
3737 remote-vx.c, remote.c, target.c, target.h,
3738 Update target_ops vector to add attach, close, and load entries.
3739 Use add_syms_addr_command, not add_file_addr_command, for
3740 add_file. Break out close routine from existing code.
3742 * dbxread.c (really_free_pendings): Don't free pending_blocks;
3743 they are in an obstack.
3744 (read_dbx_symtab): Relocate end_of_text_addr in the psymtab.
3746 (define_symbol): Add symbol type parameter; change callers;
3747 pass type parameter to DBX_PARM_SYMBOL_CLASS macro to allow
3748 it to influence the symbol class on the i960.
3749 (define_symbol): Swap LOC_CONST's into target byte order.
3751 * exec.c (exec_close): New function.
3752 (exec_file_command): Call it.
3754 * findvar.c (read_relative_register_raw_bytes): Doc byte order,
3755 Fix byte order of frame pointer.
3756 (read_var_value): Result of 0 if var's value can't be found,
3757 e.g. missing FRAME_ARGS_ADDRESS. Byte-swap LOC_CONST and
3758 LOC_LABEL values to target order. Add LOC_LOCAL_ARG.
3759 (locate_var_value): Use read_var_value and use its lazy address
3760 as the location of the var's value. Lint.
3762 * i960-pinsn.c (next_insn): Add routine from vxgdb for scanning
3765 * i960-tdep.c (arg_address, i960_frame_find_saved_regs): Remove
3766 obsolete Intel versions in favor of vxgdb versions.
3767 (check_host, byteswap, byteswap_val, reorder_val): Eliminate
3768 code dealing with byte order of values, which Intel did in host byte
3769 order rather than gdb-4's target byte order.
3770 (i960_frame_chain_valid): Move to nindy-tdep.c.
3771 (examine_prologue, skip_prologue, frame_find_saved_regs,
3772 frame_args_address, leafproc_return, saved_pc_after_call,
3773 pop_frame): Add vxgdb versions from Mark Fox.
3774 (examine_prologue, frame_struct_result_address): Add code
3775 to deal with the saved value of G13 (struct return address
3777 (frame_args_address): Modify Mark's version to prefer the
3778 saved value over the current value in the topmost frame.
3779 Cache result in the frame info to avoid performance hair in
3781 (print_fault): Add gdb960 code for printing faults.
3782 (_initialize_i960): Actually call check_host.
3784 * ieee-float.c (ieee_extended_to_double, ieee_double_to_extended):
3785 add stub routines. FIXME, these currently just return zero!
3787 * infcmd.c (program_info): Use PRINT_RANDOM_SIGNAL.
3788 (attach_command): Call target_attach, not target_open, now.
3790 * infrun.c (normal_stop): Make global, not static, for vx_attach.
3791 (child_attach): Rename from child_open.
3792 (wait_for_inferior): Use PRINT_RANDOM_SIGNAL. If stop_pc is zero,
3793 don't confuse it with a zero step_resume_break_address.
3795 * inftarg.c (child_detach): Eliminate inferior_pid test.
3796 (child_files_info): Clean up message a bit.
3797 (child_ops): Use child_attach, not child_open, to attach.
3799 * mem-break.c: #ifdef out the whole file if BREAKPOINT is not
3800 set (e.g. on VxWorks or NINDY). Move read_memory_nobpt from
3801 findvar.c to here, since it depends on the contents of the
3802 shadow_contents of breakpoints, but keep if #if 0 since it is
3805 * nindy-tdep.c: New file, contains nindy_frame_chain_valid, moved
3808 * printcmd.c (address_info): Handle LOC_LOCAL_ARG. Lint.
3809 (ptype_command, display_command): Eliminate have_inferior_p and
3810 have_core_file_p in favor of target_has_stack or
3811 target_has_execution.
3812 (print_frame_args): Handle LOC_LOCAL_ARG. Eliminate duplicate
3813 code for actually finding the values of arguments, though we still
3814 keep track of the maximum stack offset for use in printing unnamed
3815 arguments. Handle missing FRAME_ARGS_ADDRESS.
3817 * remote-nindy.c (i960_print_fault): Move to i960-tdep.c.
3818 (struct nindy_regs): Define registers passed to/from nindy.
3819 (nindy_fetch_registers, nindy_store-registers): Translate between
3820 nindy and GDB formats for the registers.
3821 (dcache_init): Statically allocate the cache, since it was being
3822 allocated by a malloc that was never freed anyway.
3823 (nindy_create_inferior): Error, not core dump, if no exec file.
3824 (nindy_before_main_loop): Use target_load, not target_add_file.
3826 * remote-vx.c (net_load): Specify large timeout for load
3827 requests. Allow user to break out with INTERRUPT.
3828 (net_break): Remove useless code, clean up. Change callers.
3829 (parse-args, skip_white_space, find_white_space): Clean up arg
3830 parsing to cope with quoted strings.
3831 (net_wait, net_quit): Never call error, just return status.
3832 (vx_read_register, vx_write_register): Cleanup status checking.
3833 #ifdef the code based on which CPU we are using (960 or 68k),
3834 FIXME, this should be completely general but it isn't yet.
3835 (vx_xfer_memory, vx_resume): Cleanup status checking.
3836 (vx_run_files_info): Improve message.
3837 (vx_load_command): Renamed from vx_add_file_command. Allow load
3839 (net_ptrace): Remove unused routine.
3840 (vx_wait): Adopt code from vxgdb960 to cope with broken
3841 connections to target machine and prompt to disconnect. Remove
3842 debug printouts. Map some EVENT_'s to SIGnals.
3843 (add_symbol_stub, vx_open): Print names of object files we found,
3844 and "ok" if we read their symbols OK. Clarify output in general.
3845 (vx_attach, vx_detach, vx_kill): Add these commands.
3846 (vx_convert_from_virtual, vx_convert_to_virtual): Simplify.
3847 (vx_run_ops): Turn off all_mem, to avoid spurious msg in the
3848 "info files" output, and create_inferior, since we already have
3851 * stack.c (frame_info): Replace Frame_unknown with 0.
3852 (print_frame_arg_vars): Handle LOC_LOCAL_ARG.
3853 (return_command): Pop until the PC matches as well as the FP,
3854 so it works even if the FP is shared with another function,
3855 as in "frameless" or "leaf" procedures.
3857 * symfile.c (load_command): renamed from add_file_target_command.
3858 (add_syms_addr_command): renamed from add_file_addr_command.
3859 (add_syms_command): Stub to call target_add_syms.
3860 (_initialize_symfile): Change command names and descriptions,
3861 add-file => add-syms, and load from alias to its own command.
3863 * target.c (kill_or_be_killed, maybe_kill_then_attach,
3864 maybe_kill_then_create_inferior): Default for attempts to start
3865 a process, if one is already running, is to ask about killing
3866 it and retry if yes.
3867 (upstack_create_inferior): #if-0 it, strata obsolete it.
3868 (push_target, unpush_target, pop_target): to_close() a target
3869 before unstacking it.
3870 (target_info): Renamed from target_files_info.
3871 (_initialize_targets): Rename "i files" as "i target", accessible
3874 * target.h: Improve comments about the target_ vectored routines.
3876 * tm-i960.h: Remove NINDY-specific stuff to tm-nindy960.h.
3877 Convert commenting style to standard GNU style.
3878 (DBX_PARM_SYMBOL_CLASS): allow LOC_LOCAL_ARG's to be recognized.
3879 (SKIP_PROLOGUE): No longer a no-op.
3880 (SAVED_PC_AFTER_CALL): Now handles leaf procedures.
3881 (*_REGNUM): Sort register numbers.
3882 (REGISTER_BYTES, REGISTER_BYTE, REGISTER_RAW_SIZE,
3883 MAX_REGISTER_RAW_SIZE, REGISTER_CONVERTIBLE,
3884 REGISTER_CONVERT_TO_VIRTUAL, REGISTER_CONVERT_TO_RAW): Float regs
3885 are now 10 byte extendeds, not 8 byte doubles.
3886 (FRAME_CHAIN_VALID): Make this config-dependent, since it differs
3887 for nindy versus vxworks targets. FIXME, this should possibly go
3888 in the target vector.
3889 (EXTRA_FRAME_INFO, INIT_EXTRA_FRAME_INFO): Cache both
3890 frame_saved_regs and arg pointer with each frame.
3891 (FRAMELESS_FUNCTION_INVOCATION): New leafproc support.
3892 (FRAME_ARGS_ADDRESS): Use cached result.
3893 (FRAME_ARGS_ADDRESS_CORRECT): New, avoids g14 guessing.
3894 (FRAME_FIND_SAVED_REGS): Change arg to subsidiary fn.
3895 (PRINT_RAMDON_SIGNAL): Call print_fault.
3896 (POP_FRAME): Now works.
3898 * tm-nindy960.h: Break this off tm-i960.h. NINDY-specific
3899 option parsing and startup; STACK_END_ADDR, FRAME_CHAIN_VALID,
3900 BREAKPOINT, and DECR_PC_AFTER_BREAK are here.
3901 (ADDITIONAL_OPTION_HANDLER): use target_load, not
3904 * tm-vxworks960.h: Break this off tm-i960.h. VxGDB specific
3905 startup; DECR_PC_AFTER_BREAK, and FRAME_CHAIN_VALID are here.
3907 * valarith.c (value_subscripted_rvalue): Avoid handling
3908 floats and doubles specially; it gave alignment errors. Lint.
3910 * valops.c (value_of_variable, value_of_this): Error if unknown
3913 * valprint.c (print_floating): Bcopy rather than pointer-deref,
3914 to avoid alignment problems.
3915 (value_print): Handle unknown value address.
3916 (cplus_val_print): Two args are ignored; remove them. Change caller.
3917 (val_print): Use unpack_long rather than pointer-deref.
3920 (unpack_long, unpack_double): Use bcopy rather than pointer-deref
3921 to avoid alignment problems.
3922 (value_being_returned): Error if return value unknown.
3923 (set_return_value): Add bogosity warning, FIXME. *
3925 * TODO: A woman's work is never done.
3927 * Makefile.dist: Distribute REMOTE_OBS into tconfig files.
3928 Separate INCLUDE_CFLAGS for use with lint. Add LINTFILES.
3929 Add ieee-float.o to OBS.
3930 * tconfig/{nindy960,vxworks68,vxworks960}: Include the desired
3931 REMOTE_OBS remote-interface files in the TDEPFILES and TM_FILE.
3932 * tconfig/i960: FIXME. Half-merge, produce warning if config'd.
3934 Changes to generalize the VxWorks RPC protocol slightly, to handle
3935 i960 as well as 68000.
3937 * vx-share/dbgRpcLib.h (VX_SOURCE_STEP): Add.
3938 * vx-share/reg.h: Produce i960 regs #ifdef I80960
3939 * vx-share/xdr_ptrace.c: Skip FPA registers if 960.
3940 * vx-share/xdr_rdb.h: Add SOURCE_STEP struct and xdr decl.
3941 * vx-share/xdr_rdb.c: Add xdr_SOURCE_STEP routine.
3942 * vx-share/xdr_regs.c: Add xdr_regs, xdr_fp_status, xdr_ext_fp
3943 for i960. Change xdr_vectors to xdr_opaques for 68k registers,
3944 so they will move in target byte order rather than network
3945 byte order (happens to be the same).
3947 Mon Feb 25 03:41:44 1991 John Gilmore (gnu at cygint.cygnus.com)
3949 * tm-convex.h (END_OF_TEXT_DEFAULT): Remove #if 0'd block.
3951 Sun Feb 24 00:55:53 1991 John Gilmore (gnu at cygint.cygnus.com)
3954 Add contribution lines to various files, showing where they
3957 * breakpoint.c (break_insn, check_break_insn_size,
3958 read_memory_nobpt): Remove to mem-break.c.
3960 * xm-*.h, param-no-tm.h, tm-29k.h, valprint.c: Change BYTE_ORDER to
3963 * tm-29k.h (STAB_REG_TO_REGNUM): Warn user if symbol table
3964 entry has bad register number. This change is not
3965 tested in this release, FIXME.
3967 * frame.h: Eliminate Frame_unknown in favor of a simple zero.
3970 * value.h: Force value's contents field to be aligned to hold
3971 at least a double or a long long (if supported). This avoids
3972 doing bcopy's in and out of the contents field.
3974 (step_1): Avoid coredump under obscure circumstances when we
3977 * symtab.h (misc_info): Add field to misc function vector for
3978 any kind of cached information the target code desires. AMD
3979 29000 uses this to avoid repeating examine_function_prologue's.
3981 * coffread.c: Lint. Remove static symfile, read_section_header.
3982 core.c (have_core_file_p): Lint: remove.
3983 expprint.c (print_subexp): Lint.
3984 infptrace.c, valops.c, valprint.c: lint.
3986 Roll in changes from vxgdb-5.0.1:
3988 * symtab.h: Comment byte order of each address class. Add
3989 LOC_LOCAL_ARG for frame-relative args (960).
3990 expread.y: Use LOC_LOCAL_ARG where LOC_ARG is used.
3991 symtab.c, symmisc.c: ditto.
3993 * infrun.c (init_wait_for_inferior): Clear stop_signal.
3995 * remote.c (remote_resume): Error if resume with a signal.
3997 * symfile.c (prim_record_misc_function): Clear misc_info.
3998 (fill_in_vptr_fieldno): Check stub type of arg.
4000 * valops.c (value_cast): Avoid looking up names of types whose
4001 name we don't know, to prevent coredump. Sun CC produces typedef
4002 rtx and the name of *rtx is zero...
4004 Mon Feb 18 21:16:25 1991 John Gilmore (gnu at cygint.cygnus.com)
4006 Roll in changes from final AMD 29000 port (Tiemann).
4008 tconfig/am29k: Add COFF_ENCAPSULATE and TARGET=TARGET_AM29K
4009 for ../include/a.out.encap.h. This might not work now that BFD
4010 is separately compiled. Instead, BFD support for encap will have
4011 to translate machine type 29k into the right COFF_MAGIC.
4013 * infcmd.c: Remove references to inferior_pid that aren't used
4014 in actual ptrace calls; use target_has_execution, etc.
4015 (have_inferior_p): Remove function.
4016 (program_info): Print target info rather than "process number";
4017 avoid gratuitous messages unless from_tty.
4018 (run_stack_dummy, finish_command): Set proceed_to_finish.
4019 infrun.c: Remove inferior_pid refs. Decl & init proceed_to_finish.
4020 main.c: Lint. Lose have_inferior_p().
4021 inferior.h (have_inferior_p): Remove, lint.
4022 (proceed_to_finish): Add flag to ask that all regs be saved
4023 by normal_stop, for the few commands that need it, speeding up
4024 serial I/O. Add comments to stop_registers.
4026 * remote-eb.c: Remove newline from breakpoint message we grep
4027 for. Never time out when running the user program.
4031 Wed Feb 13 15:34:40 1991 John Gilmore (gnu at cygint.cygnus.com)
4033 Roll in changes from vxgdb-5.0.1:
4035 * dbxread.c (read_dbx_symtab): If we encounter a "FORTRAN COMMON"
4036 symbol in its raw form, we are processing an unlinked ".o" file.
4037 See if the target environment has assigned it an address, using
4038 target_lookup_symbol (VxWorks does), and enter it into the symtab
4041 * tm-vxworks.h (FRAME_CHAIN, FRAME_CHAIN_VALID): Override usual
4042 68k versions for a simpler version that assumes zero FP at bottom.
4043 Fixes bug of truncated stack reports.
4045 * target.h (target_lookup_symbol): Define this routine's args
4046 and result, finally.
4048 * target.c (nosymbol): Default routine for target_lookup_symbol.
4049 (target_default): Default lookup_symbol and call_function too.
4050 (files_info): Only print has_all_memory warning if a non-dummy
4053 * remote-vx.c (vx_read_register, vx_convert_to_virtual,
4054 vx_convert_from_virtual): If target does not have floating point,
4055 zero register "values", and avoid doing cross-net conversions.
4056 (vx_lookup_symbol): Rename net_lookup_symbol, add to vectors.
4057 (vx_open): Rearrange code that attaches to target and reads
4058 symbols for all loaded modules, to work if some of the modules
4059 are not accessible. Add symbol_stub() and add_symbol_stub()
4060 as callbacks from catch_errors(). Allow connect attempt to be
4061 interrupted painlessly with ^C (FIXME, there are still some bugs
4062 if the interrupt happens during symbol reading.). Print
4063 final message with puts_filtered, since symbol messages are
4068 * main.c (catch_errors): Only print errstring if non-null.
4069 (command_loop): Avoid an ioctl per command to test ISATTY.
4071 * remote-vx.c (net_load): make static; avoid sophomoric msg.
4072 (vx_xfer_memory): Return correct result!
4073 (vx_files_info): Indicate whether target has float or not.
4074 (vx_lookup_symbol): Complain, not error, if target gone.
4075 (vx_open): Print "Connected" msg before disabling immediate-quit.
4076 [FIXME: lookup_symbol and vx_open changes need testing.]
4078 target.c, remote-eb.c, inftarg.c, am29k-opcode.h, target.h,
4079 tm-29k.h, tmm-vxworks68.h, symfile.c, gdb-int.texinfo: Add
4080 contributor lines and update copyrights to 1991.
4082 Changes from an attempted H-PUX host port:
4084 * infptrace.c (PT_ATTACH, PT_DETACH): Handle HP/UX, which
4085 defines PT_ATTACH and PT_DETACH but not PT_KILL.
4086 * remote-eb.c (eb_open): Misplaced endif kills sysv H/PUX.
4087 * remote-vx.c: include <sys/time.h> for HPUX.
4088 * hp300hpux-xdep.c (fetch_core_registers): Rewrite old
4089 "core_file_command" routine to BFD regime. May not work yet.
4091 Attempted port of "gdb-3.4 Van Jacobson xgdb" to modern gdb.
4093 * xgdb.c: Replace X10 version with some VJ version.
4094 (FIXME: Its copyright assignment is not on record.)
4095 * xgdb.c: Update include files to X11R4 (Xaw crud).
4096 (xgdb_display_source, create_text_widget): fix call to
4097 get_filename_and_charpos. Rewack source window stuff for X11R4
4098 (gleaned from include files, and "nm's" of binary libraries, since
4099 I had no doc available).
4100 (append_selection, append_selection_word): Disable with FIXME
4101 since R4 changed interface here.
4102 (create_buttons): Add back the old set of buttons.
4103 (xgdb_create_window): Fix call to XtInitialize (&argc not argc).
4105 * Makefile.dist (xgdb, xgdb-init.c): Update for X11R4 on Suns.
4106 Roll VERSION to 3.94 (not yet final though).
4108 Sat Feb 9 09:46:25 1991 John Gilmore (gnu at cygint.cygnus.com)
4110 * obstack.h (obstack_ptr_grow, obstack_ptr_grow_fast,
4111 obstack_int_grow, obstack_int_grow_fast): Eliminate
4112 cast on left of assignment, which gives MIPS cc fits and is
4115 * sparc-pinsn.c (print_insn): Eliminate 'set' test, subsumed by
4116 F_ALIAS. Use printf, not fprintf, when not passing a file
4118 (compare_opcodes): Check that identical instructions have
4119 identical opcodes, complain otherwise.
4121 * sparc-opcode.h (st %fsr): Fix opcode "lose" mask. This
4122 was reported by Roland McGrath.
4123 (unimp): Only match if exactly zero instruction. (Roland)
4124 (branches and traps): Generate all variations of these
4125 instructions with macros, based on a single call that defines
4126 each condition name and its binary representation.
4127 (set): Turn on alias bit, to avoid test in sparc-pinsn.c.
4129 * valprint.c (val_print_fields): Take, and use, format parameter.
4130 This means that "p/x struct" again prints the elements in the
4131 desired format. Changed callers.
4133 * stack.c (frame_info): Use filtered output, and indicate wrap
4134 points. Remove kludgy formatting designed to avoid line wrap.
4136 * utils.c (wrap_here): If the line is already full (because
4137 we had printed a long indent or long wrapped string), do an
4138 immediate newline-and-indent.
4140 * m68k-pinsn.c (print_insn_arg): Bugfix from
4141 ntmtv!thompson@ames.arc.nasa.gov (Mike Thompson): 'bkpt #0'
4142 instruction is incorrectly disassembled as bkpt #8.
4144 * dbxread.c (end_psymtab): Bugfix from Peter Schauer
4145 <pesrem@regent.e-technik.tu-muenchen.de>: If you want to set a
4146 breakpoint in a *.y file gdb will say Reading in symbols for *.y...
4147 and then will dump core (sometimes). I traced it back to an
4148 uninitialized symfile_name in psymtab_to_symtab.
4149 (const_vol_complaint): Add quotes to message.
4150 (define_symbol): Only believe line number if gcc_compiled.
4151 Avoid allocating symbol if we will not return it.
4153 Add target strata support so that newly established targets go
4154 into their right place in the target stack (e.g. a new exec file
4155 doesn't wipe out the ability to access the running process).
4157 * target.h, core.c, exec.c, inftarg.c, remote-eb.c,
4158 remote-nindy.c, remote-vx.c, remote.c, target.c: Add to_stratum
4159 and initialize it properly in all the targets.
4161 * target.h: Document strata. Change return type of push_target.
4163 * target.c (nomemory): new function for dummy memory access.
4164 (tcomplain): Rename complain, now also used in symfile.c.
4165 (push_target): Push targets within strata. New return value shows
4166 whether new target is on top of stack or not. Always keep dummy
4168 (target_files_info): Ignore dummy target.
4170 * core.c (core_open): Warn user, and skip accessing file, if the
4171 core target is not the topmost target in the stack.
4172 * remote-nindy.c (nindy_create_inferior): Avoid unpush_target, now
4175 * remote-vx.c: Remove vx_prepare_to_store from vxworks memory
4176 target_ops, it doesn't belong there since we have no regs there.
4177 Change name of target from machine => memory to clarify.
4179 Thu Feb 7 16:32:09 1991 John Gilmore (gnu at spiff.cygnus.com)
4181 * Freeze version 3.93 for release.
4183 * Makefile.dist: Handle vx-share and nindy-share subdirs
4184 properly when building gdb.tar.Z.
4186 * symtab.c: lint; add no_symtab_msg to consolidate the messages
4187 printed in various places, so I could change just one copy.
4189 * dbxread.c, coffread.c: Change references to bfd->iostream
4190 to cast to FILE *, now that BFD avoids needing types defined
4191 in other header files.
4193 Tue Feb 5 21:39:35 1991 John Gilmore (gnu at cygint.cygnus.com)
4195 * command.c, dbxread.c, expprint.c, infcmd.c, infptrace.c,
4196 infrun.c, printcmd.c, remote-nindy.c, source.c, sparc-tdep.c,
4197 sparc-xdep.c, symfile.h, symmisc.c, utils.c, valprint.c: Lint
4198 (actually gcc -Wall).
4200 * dbxread.c: Remove first_global_sym, last_global_sym, since
4201 they are never referenced.
4203 * defs.h (baud_rate): Declare.
4204 main.c: Define it, and add the -b option to set it.
4206 * gdb-int.texinfo: Add text on how to define a new host or target
4207 architecture, prompted by Per Bothner's questions about MIPS
4210 * gdb.texinfo: Document "complaints". Change doc of -q since
4211 gdb no longer prints the copyright and blurb if you specify a file
4212 name to be debugged (just like Emacs). Add doc for Nindy-specific
4213 command line flags for specifying target serial port and such.
4214 Update copyright to 1991.
4216 * gdbcore.h: Remove a large mass of now-useless crud, since BFD
4217 has taken over for us the job of ripping up executable files. The
4218 crud caused Per Bothner's port to not compile.
4220 * infrun.c (normal_stop): Avoid printing "Program exited
4221 normally" if we are in batch mode. This allows a GDB which
4222 executes a program on a target system, to behave like a Unix
4223 command (input from stdin, output to stdout, no extraneous
4226 * main.c (main): Allow additional machine-dependent command line
4227 options to be specified with the ADDITIONAL_OPTIONS,
4228 ADDITIONAL_OPTION_CASES, ADDITIONAL_OPTION_HELP, and
4229 ADDITIONAL_OPTION_HANDLER macros. Also allow machine-dependent
4230 processing to occur just before the main loop with
4231 BEFORE_MAIN_LOOP_HOOK.
4232 (main): If a "core file" argument is specified, and it is not a
4233 core file, try it as a process ID to attach.
4234 (symbol_completion_function): Attempt to cope with
4235 "show screen-" TAB, not very successfully. This needs more work,
4237 (batch_file): New function, returns whether we are reading
4238 commands from an interactive tty on stdin, or from somewhere else.
4239 Called by normal_stop since it doesn't get from_tty passed down
4240 to it like many commands do.
4242 * remote-nindy.c: Handle command line options for nindy
4244 (nindy_before_main_loop): Prompt user for tty name if they
4245 don't specify it before getting to the interactive command loop.
4247 * tm-i960.c: Add ADDITIONAL_OPTIONS, etc, to handle -O, -brk,
4248 and -r command line options. Also add hook before main loop
4249 to make it easy to specify a tty.
4251 * TODO: More things to do, one done.
4253 Mon Feb 4 23:57:39 1991 John Gilmore and Mike Tiemann (at cygint.cygnus.com)
4255 * dbxread.c: Make complaint() calls pass pointer, not struct.
4256 Add complaints about badly formatted C++ type information
4257 (const/volatile indicator, and parse errors resulting in
4258 error_type). Fix C++ virtual member fn comment.
4259 (read_struct_type): Avoid bumping pointer if we got a parse
4260 error; this prevents our walking beyond the end of a string.
4261 Terminate loop on null char as well as semicolon.
4262 (process_one_symbol): Fix the LBRAC fix so that it uses the
4263 last previous SLINE, FUN, or SO record's PC address. C++ debug
4264 symbols did not have SLINE records in a useful order compared
4265 to the LBRAC records.
4266 (define_symbol): Handle "catch" records.
4268 * symtab.c (check_stub_type): Added new complain
4269 `stub_noname_complain' and added a consistency check to
4270 keep the debugger from crashing when finishing from an
4271 exception frame. A real fix will be needed later.
4273 Sat Feb 2 10:43:05 1991 John Gilmore (gnu at cygint.cygnus.com)
4275 * infcmd.c (attach_command): Make global.
4277 * Makefile.dist (REMOTE_OBS): Make these compile by default,
4278 but make them easy to comment out. Perhaps later they should
4279 be enabled by what CPU you configure for? FIXME.
4280 (VERSION): Roll to 3.93.
4281 (pinsn.o): Remove rule for obsolete file.
4282 (dbxread.o,coffread.o,mipsread.o): Use ${srcdir} explicitly.
4284 Run down a problem that manifested by printing the wrong function
4285 name in stack traces of read_ofile_symtab. Turned out that the
4286 problem was the SunOS 4.1.1 (and previous) C compiler outputs
4287 the LBRAC symbol with an address in the *data* segment, which
4288 blew our binary search through the blocks.
4290 * dbxread.c: Use the complain() facility consistently to bitch
4291 about problems in the symbol file we are reading.
4292 (finish_block): Add code to check the nesting of the blocks;
4293 complain and Procrust them to fit if wrong.
4294 (make_blockvector): Check the order of the blocks, complain
4295 [but don't cope] if wrong.
4296 (process_one_symbol): ifndef SUN_FIXED_LBRAC_BUG, check LBRAC
4297 symbols to be sure their PC value is greater than the last SLINE
4298 (line number) symbol we've seen, complaining and adopting the
4299 SLINE PC value if wrong.
4301 * symfile.h (struct complaint, complaint_root, complain,
4302 clear_complaints): Add.
4303 * symfile.c (complain, complaint_root, clear_complaints): Add
4304 facility to deal with non-fatal complaints and to regularize their
4306 (symbol_file_add): Clear complaint counters to allow new complaints.
4307 (initialize_symfile): Add 'set complaints' and 'show complaints'.
4309 * dbxread.c (dbx_symfile_read): Remember the address and size
4310 of the string table for the main symbol file, so we won't read it
4312 (dbx_psymtab_to_symtab): Fix the check for main symbol file,
4313 to avoid reading the string table yet again. Lint.
4314 (throughout): Improve filtered output, including word wrap.
4315 (read_range_type): Improve Bothner's fix to handle other types too.
4317 * utils.c: Improve line wrap implementation. Handle unlimited
4318 width by making chars_per_line unsigned.
4319 (puts_filtered): New, easy, function.
4321 * defs.h (puts_filtered): add.
4323 * mipsread.c (compare_symbols, sort_symtab): Remove these fns,
4324 call the identical sort_symtab_syms() in symfile.c instead.
4326 * expread.y: Suggest the `file' command rather than `symbol-file'.
4328 * command.h (enum var_types): Add zinteger for seroable
4330 * command.c (do_setshow_command): Handle var_zinteger. Restructure
4331 nested if's into a switch.
4333 * breakpoint.c (bpstat_print): If bpstat "print" flag is not set,
4334 we did not stop because of a breakpoint (it must have been for
4335 some other reason, like a "stepi"), so don't print anything.
4337 * symtab.c: Include <sys/types.h> all the time. Now that BFD
4338 doesn't include <sys/types.h>, old SunOS's require it for
4341 Sat Feb 2 10:39:15 1991 Per Bothner (bothner@cs.wisc.edu)
4343 A test port of gdb-3.92.6 to the Sony NEWS.
4346 Don't normally link in remote- or vx stuff.
4347 Some of it doesn't compile, and it wastes space for 99% of the users.
4348 Remove reference to no-longer-used HAVE_VPRINTF.
4349 Fixed BFD_DEP typo to BFD_DIR.
4351 Fix cast in arg to bfd_h_getlong.
4352 Make char *prefix be const.
4353 Fix how certain range types are mapped into builtin unsigned int types.
4355 Remove 2 #includes. They cause errors (on Sony, at least),
4356 and aren't needed (they wern't in earlier versions).
4358 print_address_symbolic should never demangle labels
4359 (since it prints *assembler-level* labels).
4361 [This was superseded by the change to printcmd below.]
4364 Add some "volatile" return types to avoid warnings.
4365 If MISSING_VPRINTF add vprintf function and not just macro
4366 (since vprintf is used in printcmd.c).
4368 Unless __GNUC__, use obstack_grow instead of obstack_ptr_grow.
4369 (The latter isn't grokked by some PCC-based compilers.)
4371 [This change is in abeyance, we prefer to fix obstack_ptr_grow.]
4373 Make chunk size of dont_print_obstack 32*4 instead of default 4096.
4374 * nindy-share/coffstrip.c
4375 Added some forward declarations (otherwise, gcc complains
4376 about implicit extern redefined as static).
4378 Sun Jan 20 02:38:19 1991 John Gilmore (gnu at cygint.cygnus.com)
4380 Changes inspired by Per Bothner:
4381 * printcmd.c (print_address_symbolic): Take additional parameter
4382 specifying whether to demangle.
4383 (print_address): Pass in asm_demangle to control demangling.
4384 (print_address_demangle): New fn, takes explicit arg to control
4386 * utils.c: Add new vars demangle and asm_demangle, and let them
4388 (fputs_demangled): If !demangle, just print the argument.
4389 (fprint_symbol): If !demangle, just print raw symbol.
4390 * valprint.c (val_print): Call print_address_demangle rather than
4391 print_address, to cause demangling to depend on the global
4392 rather than assembler-level demangling setting.
4393 * WHATS.NEW, gdb.texinfo: Document.
4395 * main.c (show_command): Show all settings if no arg.
4396 (initialize_main): Make "info set" the same as naked "show".
4397 * command.c (cmd_show_list): Handle prefix commands in the
4398 list, and print the name of the setting as well as its English
4399 description and value.
4401 Allow gdb functions to specify where a line should wrap if it
4402 exceeds the size of a terminal line. Use it to make the output
4404 * utils.c (set_screen_width_command): New fn, mallocs a buffer
4405 of the right size when screen width changes.
4406 (set_screensize_command, screensize_info): Remove #if 0'd fns.
4407 (wrap_here): New fn, indicates a point in the output where we
4408 should wrap the line rather than just letting it overflow at a
4410 (fputs_filtered): Implement wrapping.
4411 (n_spaces): New fn, returns a pointer to N spaces.
4412 (print_spaces_filtered): Use n_spaces.
4413 * defs.h (n_spaces): Declare.
4414 * stack.c (print_frame_info): Wrap with 4-space indent after
4415 fn name and before filename and line number.
4416 * printcmd.c (print_frame_args): Wrap with 4-space indent
4417 before each argument name is printed.
4418 * valprint.c (value_print): Wrap with no indentation before
4420 (val_print_fields): Wrap with indentation relative to nesting
4421 level before each field name.
4422 (val_print): Wrap with nesting indentation before array elements.
4423 * command.c (do_setshow_command): Avoid extra newlines,
4424 wrap with 4-space indent around values printed, end with period.
4425 * WHATS.NEW, gdb.texinfo, gdb-int.texinfo: Document.
4427 * breakpoint.c (breakpoint_1): Implement addressprint for
4428 "info breakpoints" display. Change file name and line number
4429 format to " at file:nnn" rather than " (file line nnn)".
4430 * gdb.texinfo: Document.
4433 Fri Jan 18 07:21:25 1991 John Gilmore (gnu at cygint.cygnus.com)
4435 Frozen for gdb-3.92.6 release.
4437 README, WHATS.NEW: Update for 3.92.6 release.
4439 tconfig/{altos, i386v, i386v32, m88k, umax}: Eliminate
4440 coffread.o from configs since it is now built by default.
4441 tconfig/{3b1, altosgas, arm, convex, hp300bsd, hp300hpux,
4442 i386v-g, i386v32-g, isi, merlin, news, news1000, np1, pn,
4443 pyramid, symmetry, vax, vxworks68}: Eliminate dbxread.o
4444 from configs since it is now built by default.
4446 Makefile.dist: Update for release 3.92.6. Handle files that
4447 have been moved to ../include, ../getopt, or ../bfd. Add
4448 saber.suppress and tests directory. Add config.status to
4449 the release (it will say "none").
4451 coredep.c: Minor formatting fixes.
4453 These changes were made in early December but only checked in now:
4454 * nindy-share/Onindy.c, nindy-share/coffstrip.c,
4455 nindy-share/nindy.c: lint
4456 * nindy-share/nindy.c (ninStopWhy): Don't byteswap the
4457 register values coming back from the target; we store values
4458 in target byte order everywhere.
4460 Wed Jan 16 19:01:37 1991 John Gilmore (gnu at cygint.cygnus.com)
4462 * am29k-opcode.h, am29k-pinsn.c: Add 29050 opcodes.
4464 * valprint.c (cplus_val_print, val_print_fields): New functions,
4465 which print C++ objects. They conspire to avoid printing a
4466 virtual base class more than once, following all the twists and
4467 turns of C++ virtual base rules.
4468 (val_print): Call the above rather than do it by hand.
4470 * symfile.c (symbol_file_add): Only reset symfile_mtime for main
4471 symbol file, not for added files like shared libs. This really
4472 needs to be generalized to a timestamp per file.
4474 * core.c (cleanup_core): Avoid coredump if no core file.
4476 * config.gdb: Accept -host or -target in place of +host or
4479 * coffread.c (find_linenos): Avoid desupported BFD interface
4480 to line numbers. We still read them manually rather than using
4481 BFD's "generic" features.
4483 * gdbrc.tex, threecol.tex: Add GDB reference card and its
4485 Makefile.dist: Add refcard to OTHERS list for creating tar files.
4487 * Makefile.dist: Eliminate use of $< in explicit targets.
4489 * readline/Makefile: Use $< rather than $*.c, which does not
4490 include the VPATH in GNU Make.
4492 * tconfig/i960-bout, tconfig/i960-coff: These are identical
4493 copies of tconfig/i960, added for global configuration
4494 compatability. All i960 versions can read both coff and b.out.
4496 * tm-88k.h: Fix multiline macro that lacked \'s. Remove
4497 COFF_FORMAT and COFF_CHECK_X_ZEROES since these are now handled
4500 * TODO: Think of more things to do.
4502 Wed Jan 2 19:09:29 1991 John Gilmore (gnu at spiff.cygnus.com)
4504 tconfig/{am29k,i960,sun2*,sun3*,sun4*}: Eliminate config
4505 of sdb versus dbx debug symbols. Add kludge for 68881 80-bit to
4506 64-bit float conversion.
4508 tconfig/sun4, tconfig/sun3, xconfig/sun4, xconfig/sun3: Make
4509 equivalent to sun?os4 so global config works.
4511 Wed Jan 2 18:20:51 1991 John Gilmore (gnu at spiff.cygnus.com)
4513 Fix from Eberhard Mattes <mattes@azu.informatik.uni-stuttgart.de>
4515 * main.c: Only declare linesize once; declare pagesize not at
4516 all, since it is never used.
4517 (main): Clear newly allocated line before it is used.
4519 Fri Dec 28 00:13:42 1990 John Gilmore (gnu at cygint)
4521 Further stabilization for the Intel 960.
4523 * Makefile.dist: Parameterize the location of the "include"
4524 and "bfd" directories, as well as "getopt". Add symfile.c.
4525 Link in both dbxread and coffread. Fix up "make depend" to
4526 rewack the locations of include, bfd, and getopt in its output.
4528 * README: Document moving include files, improve some of
4531 * coffread.c: Move common code out to symfile.c. Change
4532 symbol_file_command style interface to use new *_symfile_init
4533 and *_symfile_read interface under BFD. Use BFD internal
4534 info to locate line table, symbols, etc.
4536 * core.c (core_fetch_registers): Rename to get_core_registers
4537 to avoid confusion with fetch_core_registers.
4538 (register_addr): Move to coredep.c, which is already machine
4539 dependent. This leaves core.c pretty clean of dependencies.
4541 * coredep.c (register_addr): Accept this routine from core.c.
4543 * dbxread.c: Move common code (with coffread.c, etc) into new
4544 symfile.c. Each psymtab now contains a pointer to the
4545 format-dependent function that knows how to read it in. Make
4547 (dbx_psymtab_to_symtab): Renamed from psymtab_to_symtab_2.
4548 (process_one_symbol): Add code to complain about a "compiler bug
4549 we muzzle here", if we actually see it.
4551 * eval.c (evaluate_subexp): Insert missing "break" statements
4552 in code that determines whether a variable is an lvalue in
4553 memory, register, or whatever. I detected this via a compiler
4554 bug in which it *almost* mashed out the whole switch statement.
4556 * gdb-int.texinfo: Add minor sections on configuring gdb for
4557 release, and about the README file.
4559 * infcmd.c (registers_info): Fix formatting somewhat. Still
4560 not as pretty as before, but it handles byte swapping.
4562 * remote-nindy.c: If data cache routines are interrupted while
4563 waiting for the remote end, be sure that any uninitialized cache
4564 blocks are on the free list, not on the valid list!
4566 * symfile.h: Flesh out this header file with all the various
4567 routines and variables that have been merged in from dbxread.c
4568 coffread.c, and symtab.c to symfile.c.
4570 * symfile.c: New file, containing code common to dbxread.c,
4571 coffread.c, and some code from symtab.c. All generic code for
4572 reading symbol files should be in here now.
4573 (unrecord_misc_function): Remove unused function.
4575 * symtab.h: Remove file-reading things to symfile.h.
4577 * symtab.c: Remove file-reading things to symfile.c.
4579 * tm-i960.h: Fix FRAME_CHAIN types; define PRINT_RANDOM_SIGNAL
4580 to decode i960 fault types.
4582 * target.h, remote.c, remote-eb.c, remote-vx.c, remote-nindy.c,
4583 target.c: Change type of the "resume" function from int to void,
4584 since its result was never used.
4586 Sat Dec 22 02:51:40 1990 John Gilmore (gnu at cygint)
4588 * main.c: Replace "stupid" with "caution"; you now "set caution
4591 * printcmd.c (print_scalar_formatted): Fix typo in 'g' format
4593 * infcmd.c (do_registers_info): Call val_print to deal with the
4594 byte order of the registers being printed. FIXME, this makes
4595 the formatting of the output uglier.
4597 * infcmd.c (wait_for_inferior): If PRINT_RANDOM_SIGNAL is
4598 defined, call it for signals the debugger doesn't itself use.
4599 The i960 uses this for more detailed fault information.
4601 * remote.c (remote_open): If arg is null, print help rather than
4604 * sparc-xdep.c (register_valid): Avoid declaring size, since
4605 various modules will think of various sizes depending on the
4606 architecture of their tm-file. FIXME, we need protection against
4607 actually entering one of those modules, which would clobber
4608 storage if not for the target architecture compiled into gdb.
4610 * stack.c (up_command, down_command): Always print the frame
4612 (up_silently_command, down_silently_command): New commands
4615 * i960-pinsn.c (reg), i960-tdep.c: Lint.
4617 * i960-tdep.c (i960_frame_chain_valid): Lookup_symbol now takes
4618 more parameters than it used to.
4620 * findvar.c (registers): Increase slop to 256 bytes, which should
4621 protect us against even most RISC machines with large register
4623 (locate_var_value): Move declaration inside related ifdef.
4625 * remote-nindy.c (): Use TIOCSETN rather than TIOCSETP
4626 throughout, to avoid throwing away buffered input from the board.
4627 (nindy_wait): Supply_register takes addr_of_value, not value.
4628 (i960_print_fault): Renamed from i80960_fault.
4629 (nindy_fetch_registers): Avoid have_regs stuff, just get them.
4630 (nindy_store_registers): Avoid regs_changed stuff, just stuff
4632 (nindy_create_inferior): Don't bother to write PC_REGNUM since
4633 we can set the PC in the call to proceed(). Unpush nindy_ops
4634 before pushing it on top, to avoid message to user. Eliminate
4635 commentary from Unix machines that just misleads here.
4636 (reset_command): Fix error message to suggest target command.
4638 Wed Dec 19 11:03:56 1990 John Gilmore (gnu at cygint)
4640 Release 3.92.5 as frozen.
4642 Stabilize the merged release...with help from lint, Saber C,
4645 Everywhere: Add include files needed to declare return types
4646 of functions called.
4648 * gdb.texinfo: Roland Pesch is documenting gdb, glory be!
4650 * breakpoint.h: Add undeclared breakpoint functions, and some
4651 functions for display handling since I couldn't think of a better
4654 * breakpoint.c (insert_breakpoints): Make code for disabling
4655 shared library bkpts more likely to work. It's used when we
4656 rerun a program and stop before the shared library has been
4658 (breakpoint_cond_eval, bpstat_stop_status): Pass arg as int,
4659 cast from pointer, so it squeezes through catch_errors.
4660 (bpstat_stop_status): Fix logic broken some time ago. We now
4661 always create a bpstat if the stop address matches a breakpoint,
4662 even if we don't stop there -- just like the old code used to do
4663 before I got my fingers into it (sigh).
4664 (breakpoint_1): Print "ignore count" after "stop only if"
4665 condition, since that's how it actually works.
4666 (mention): Handle watchpoints as well as breakpoints.
4667 (watch_command): use set_raw_breakpoint and mention to do most
4668 of the work (and initialize all the fields!). Only pass one
4669 arg to parse_c_expression, since that's all it takes.
4671 * command.c (not_just_help_class_command): Rename arg to args
4672 since we ignore "unused argument" warnings on vars named "args".
4673 inflow.c (child_terminal_info): ditto.
4674 infptrace.c (kill_inferior): ditto
4675 main.c (catch_errors, version_info, quit_command, pwd_command,
4676 source_command, dump_me_command, editing_info,
4677 set_history_size_command, set_history, show_history,
4679 stack.c (locals_info): ditto
4680 target.c (target_files_info): ditto
4681 valprint.c (set_input_radix, set_output_radix): ditto
4683 * core.c: Remove old variables for handling core and exec file
4684 sections (data_start, data_end, stack_start, stack_end,
4685 reg_stack_start, reg_stack_end, reg_stack_offset, text_start,
4686 text_end, exec_data_start, exec_data_end, text_offset,
4687 exec_data_offset, data_offset, stack_offset). They're
4688 superseded the more general build_section_table and
4690 (get_exec_file): Mention the `file' command.
4691 (read_memory_check): Rename to memory_error, and only call it
4692 in the case of an actual error.
4693 (read_memory, write_memory): call memory_error.
4694 (core_fetch_registers): Register section name is ".reg".
4696 coredep.c: Remove a bunch of crud now that all this file does
4697 is pull the registers out of a core file.
4698 (fetch_core_registers): Rewrite to actually work, I hope.
4700 dbxread.c: Use a.out.gnu.h, not system a.out, now.
4701 Replace index() with strchr(). Remove all the pre-BFD macro
4702 definitions for accessing the symbol file.
4703 (struct dbx_symfile_info): Encapsulate the information that
4704 dbx_symfile_init needs to pass to dbx_symfile_read in this
4707 (dbx_new_init, dbx_symfile_init, dbx_symfile_read,
4708 dbx_symfile_discard): Rearrange symbol file reading to divide
4709 the format-specific part from the format-independent part,
4710 leaving the format-independent part such as file name expansion
4711 and opening in symtab.c. This replaces
4712 partial_symbol_file_open and partial_symbol_file_read.
4713 Symbol_file_read, add_file, add_file_target_command,
4714 add_file_addr_command move to symtab.c. Pass an explicit
4715 "mainline" flag for when reading the main symbol table, rather
4716 than relying on the offset address to be zero or nonzero.
4718 (dbx_symfile_read): Don't allow void *'s to be printed as
4720 (SWAP_SYMBOL): Use bfd routines to byte-swap the symbols.
4721 (ADD_PSYMBOL_TO_LIST): Make the "function call rather than
4722 macro" debug version really work.
4723 (read_dbx_symtab): Remove unref'd parameter inclink.
4724 Avoid swapping N_SLINE symbols, for speed.
4725 Merge N_TEXT!N_EXT case with the other external symbol
4726 definitions' case. Add comments.
4727 (start_psymtab): Allocate the symfile name in the psymtab on
4728 the psymbol_obstack, rather than using the caller's storage.
4729 (end_psymtab): Only allocate a dependencies list if there are
4731 (psymtab_to_symtab_2): Use BFD when reopening file to read
4732 its symbols for real.
4733 (read_struct_type): Add FIXME comments where it needs work
4735 (read_huge_number): Add FIXME about overflows.
4736 (read_range_type): Add FIXME about comparing a long to 1<<32.
4738 * coffread.c: Minor changes to move things closer to the new
4739 regime with symtab.c and dbxread.c Major work is still needed
4742 * exec.c (exec_file_command): Remove old variables (see core.c
4744 (xfer_memory): If memory transfer is right at the end of a
4745 section, don't lose.
4747 * findvar.c (get_saved_register): If value is in a real
4748 register, LVAL is lval_register, not lval_memory.
4750 frame.h: Declare print_sel_frame and record_selected_frame.
4752 gdb-int.texinfo: New file, for GDB internals documentation.
4753 Very simple, unformatted doc of cleanups is there for now.
4755 gdbcore.h: Remove obsolete variables that described a.out
4756 section addresses and offsets. (See core.c above.)
4757 Declare fetch_core_registers and registers_fetched.
4759 getopt.c: Declare char *alloca(); even on SPARC.
4761 infcmd.c (run_command): Call target_kill rather than
4763 (step_command, next_command, stepi_command, nexti_command):
4764 Declare from_tty parameter even though we don't use it.
4765 (run_stack_dummy): argument BUFFER is a char array, not
4766 a pointer to REGISTER_TYPE.
4767 (finish_command): using_struct_return needed a value *,
4768 not a struct symbol *.
4770 * infptrace.c (child_xfer_memory): To avoid dependency on
4771 where sections are in memory, try PT_WRITE_D and if that fails,
4772 try PT_WRITE_I. Most Unixes don't care which you use.
4774 * infrun.c (step_resume_break_shadow): Change to array to
4775 match other breakpoint shadow storage.
4776 (clear_proceed_status): Pass address of bpstat to
4777 bpstat_clear, not the bpstat itself.
4778 (child_create_inferior): FIXME comment about if the child
4780 (start_inferior): Remove old function.
4781 (child_open): Use target_kill rather than kill_inferior.
4782 (wait_for_inferior): Ditto.
4783 (insert_step_breakpoint, remote_step_breakpoint): Use
4784 new step_resume_break_shadow.
4786 * inftarg.c (child_wait): If all child processes die,
4787 pretend that the one being waited for exited with signal 42.
4789 * main.c (command_line_input): When scanning for comments,
4790 don't coredump on unclosed quotes.
4791 (quit_command): Use target_kill rther than kill_inferior.
4792 (_initialize_main): Rename class_user from "user" to
4795 * printcmd.c (print_command_1): Initialize "fmt" if no format
4796 is specified by the user.
4797 (print_frame_args): Only add to args_printed if we are
4798 actually fetching args from the stack (avoiding undefined
4800 (_initialize_printcmd): Remove bogus \{ from string.
4802 * remote-eb.c (eb_open): Avoid coredump on no argument.
4804 * remote-nindy.c: Bring out of Intel environment into new
4805 target environment. Remove all conditional compilation on
4806 I80960. Massive hacking throughout.
4807 (nindy_xfer_inferior_memory): New routine stolen from
4809 (nindy_create_inferior): New routine pieced together, probably
4810 not quite working yet.
4811 (nindy_ops): New target_ops struct for nindy.
4813 * remote-vx.c: Use write_memory rather than target_write_memory
4814 to get error checking.
4815 (vx_add_file_command, vx_open): Use symbol_file_add rather than
4817 (vx_create_inferior): Use target_terminal_ours...
4819 * signame.c (_initialize_signame): Always initialize, since
4820 we need the table for things other than psignal.
4822 * solib.c (solib_add): Use symbol_file_add, not add_file.
4823 (solib_address): Return boolean result rather than struct
4824 pointer which nobody else knows the type of.
4826 * sparc-tdep.c, valops.c: Use write_memory rather than
4827 target_write_memory, to get error checking.
4829 * stack.c (locals_info, catch_info, args_info,
4830 get_selected_block, frame_command, up_command): Use
4831 target_has_stack, rather than have_inferior_p or
4834 * sun3-xdep.c (fetch_core_registers): Rewrite for new BFD regime.
4836 * symfile.h: New file, defining the interface between the
4837 generic and object-file-specific symbol reading code.
4839 * symtab.c: Move generic symbol-reading interface to symtab.c,
4840 from dbxread.c, coffread.c, mipsread.c, etc. Add symtab_fns
4841 table to map BFD targets to symbol-reading modules in GDB.
4842 Change index to strchr.
4843 (lookup_struct_elt_type): Use error() rather than hand-made
4844 simulations thereof.
4845 (lookup_partial_symbol): Speedup slightly when length == 0.
4846 (symbol_file_add): New function.
4847 (symbol_file_command): Call it.
4848 (symfile_open, symfile_init): New function.
4849 (add_file_target_command, add_file_addr_command): moved from
4852 * target.c (target_command): use target_kill.
4854 * target.h (target_files_info): Don't declare, never called
4857 * tm-sun2.h, tm-sun3.h (STACK_END_ADDR): Use system include
4858 files to determine stack end address.
4860 * valarith.c (value_x_binop, value_x_unop): Change error message
4861 to be more useful. Pass proper argument to value_struct_elt.
4863 * valops.c (value_assign): FIXME comment that long long
4864 bitfields will break here.
4866 * Makefile.dist: Add symfile.h, remote-nindy.c, remote-eb.c.
4867 Update `make saber_gdb' to work better.
4869 * TODO: A woman's work is never done.
4871 * cplus-dem.c, environ.c, inferior.h, infrun.c, inftarg.c,
4872 main.c, obstack.c, printcmd.c, remote-eb.c, remote-nindy.c,
4873 remote-vx.c, remote.c, solib.c, source.c, sparc-pinsn.c,
4874 sparc-tdep.c, sparc-xdep.c, symmisc.c, symtab.c, symtab.h
4875 target.c, terminal.h, tm-sparc.h, tm-sunos.h, utils.c,
4876 valops.c, valprint.c, exec.c: Lint.
4879 Wed Dec 12 23:44:15 1990 John Gilmore (gnu at cygnus.com)
4881 Continuing Intel 960 port merge of GDB.
4883 * Makefile.dist: Merge i960 "nindy-share" files. Rename
4884 malloc.h to gmalloc.h to avoid name conflicts in /usr/include.
4885 Don't ship gdb.dvi in tar file. Link gdb with init.o, not init.c.
4886 Wack over "make depend" so it handles files in subdirectories
4887 vx-share, nindy-share, bfd, and in the current directory.
4889 * blockframe.c (get_prev_frame_info): Remove fatal error
4890 if stack not defined.
4892 * core.c (core_open, core_detach): New functions that handle
4893 the old "core-file" command as "target core" and "detach" instead.
4894 (core_file_command): Call them.
4895 (core_xfer_memory): Use common routine xfer_memory.
4897 * dbxread.c: Include a.out.gnu.h, not system a.out.h.
4898 dbxread now uses bfd for everything but symbol reading itself.
4899 BFD internals are used to drag out the relevant file offsets.
4900 (partial_symbol_file_open): Change args all around for BFD.
4902 * symtab.c: Rename "value" to "val" everywhere, so we can
4904 (symbol_file_command): New command, moved from dbxread.c
4905 and coffread.c. It uses BFD to read the file, then vectors
4906 based on its type, to dbx or coff symbol readers.
4907 * symtab.h: Extern a few vars for symbol_file_command.
4909 * target.h: Breakpoint takes a char * save area, not a char **.
4911 * valprint.c (val_print): When unpacking bitfields, offset
4912 the address in gdb of the value, if it is declared with a shorter
4913 type. Remove the last "runtime kludge test" of host byte order.
4915 * utils.c: Remove old my_bfd_read routine.
4917 * stack.c (frame_info): Use target_has_stack. Print program counter
4918 register's actual name rather than "pc", since it's called the
4919 "ip" (instruction pointer) on the i960 (sigh).
4921 * target.c (target_command): Add command for selecting a target
4922 type and calling its open routine. This is used for initiating
4923 communication with a particular target, in a generic way.
4925 * tm-i960.h: Update for modern gdb. Remove semicolons from
4926 various macros. Handle reading struct return convention, and
4927 error-out attempts to return structs with the "return" command.
4928 Be sure gdb doesn't think we know how to call functions in the
4931 * i960-tdep.c: Rename FRAME_CHAIN_VALID and FRAME_FIND_SAVED_REGS
4932 to i960_xxx in lower case.
4933 (arg_address): Circumvent errors due to LOC_ARG_BLOCK
4934 not being defined yet.
4936 * remote.c (remote_open): Call start_remote to initialize
4937 wait_for_inferior during open.
4938 (remote_xfer_inferior_memory): Return length written rather
4941 * remote-vx.c (target_command -> vx_open): Use new generic
4943 * remote-eb.c, inftarg.c, exec.c: ditto.
4945 * infrun.c: Fix comments.
4946 (attach_program -> child_open): Use new generic target command.
4947 (wait_for_inferior): Clear saved register values before target_wait,
4948 so target_wait can set some of them if convenient.
4950 * infptrace.c (fetch_inferior_registers, store_inferior_registers):
4951 Return success indicator, not void.
4952 (child_xfer_memory): Avoid fetching initial word if we'll
4953 overwrite it anyway.
4955 * infcmd.c (attach_command): Use new generic target open routine.
4956 (_initialize_infcmd): Update doc on attach and detach commands.
4957 (do_registers_info): Merge in a byte-order problem as a FIXME
4960 * findvar.c (find_saved_register): Avoid problem in current frame.
4961 (read_relative_register): Ditto.
4962 (write_register): Convert byte order on the way out.
4964 * exec.c (file_command): Add.
4965 (add_to_section_table, exec_command): Use new bfd_map_over_sections.
4966 (xfer_memory): Common function between core_xfer_memory and
4968 (exec_xfer_memory): Use it.
4970 * pn-opcode.h: Document that a "PN" is a Gould PowerNode.
4972 * breakpoint.c, breakpoint.h, symtab.h, value.h, frame.h, utils.c,
4973 valops.c, stack.c, target.c, sparc-xdep.c, source.c, printcmd.c,
4974 infcmd.c, i960-pinsn.c, eval.c, defs.h: lint and gcc -Wall.
4976 Sun Dec 2 16:45:06 1990 John Gilmore (gnu at cygnus.com)
4978 Merge Intel 960 port of gdb, continuing...
4980 * dbxread.c (partial_symbol_file_open, partial_symbol_file_read,
4981 symbol_file_command): Pass from_tty arg to hush 'em up.
4983 * coffread.c (symbol_file_command): Avoid output if from_tty != 1.
4984 Add magic numbers for 960 COFF format.
4986 Fri Nov 30 09:18:20 1990 John Gilmore (gnu at cygnus.com)
4988 Merge Intel 960 port of gdb, from Intel "1.2" release.
4990 CHANGE_LOG entries from their port, which was based on
4993 Thu Sep 6 11:02:22 PDT 1990
4994 Remove temp file if download is interrupted.
4996 Wed Aug 1 09:08:33 PDT 1990
4997 Now uses binary protocol to talk to NINDY.
4998 Old hex protocol (NINDY 2.13 and older) supported with -O switch.
4999 Times out after 5 seconds when trying to talk to NINDY.
5001 Tue May 29 12:54:49 PDT 1990
5002 Added variable baud rate (-b switch).
5003 Source code reorganization.
5005 Thu Apr 26 11:09:55 PDT 1990
5006 More cleanup of batch mode; specifically, execute "-s", "-e", and
5007 "-se" switches as soon as they are encountered on the invocation line.
5009 Fri Apr 20 13:47:15 PDT 1990
5012 Thu Apr 19 09:54:28 PDT 1990
5013 Add 'reset' command.
5015 Wed Apr 18 09:48:07 PDT 1990
5016 After opening remote tty, wait for 1 second to go by without input
5017 from it before trying to talk to NINDY (fixes problems with the
5018 Heurikon HK80/V960E).
5020 Mon Apr 4 16:33:05 PDT 1990
5021 Some output was not being suppressed in 'batch' mode.
5023 Thu Mar 22 15:31:11 PST 1990
5024 Ask user if old symbol table should be deleted when new file is
5027 Allow user to run a program downloaded before gdb960 was brought up.
5029 Correct "exec-file" help message for i80960 context.
5031 Correct bug in calculating user space address: could occasionally
5032 corrupt user program.
5034 Make sure to zero low-order bits in rip's because of bug in 960CA
5035 A-step part: could cause operation faults when "next"ing across
5038 Correct bug that made it impossible to get source line numbers for
5039 code loaded at addresses higher than 0x7fffffff.
5041 Wed Jan 10 12:43:22 PST 1990
5042 Open remote tty for exclusive use.
5044 Fri Jan 5 12:14:42 PST 1990
5045 Correct disassembly (CA manual was right after all):
5046 opcode for sysctl is 0x659
5048 Mon Oct 23 12:03:04 PDT 1989
5049 Use G960BASE and G960BIN environment variables to find 'sx' utility.
5051 Mon Oct 16 14:15:09 PDT 1989
5052 "sfr0"-"sfr31" should have been named "sf0"-"sf31"
5054 Mon Oct 2 15:56:31 PDT 1989
5056 Added 960CA disassembly support.
5058 To simplify maintenance:
5059 - eliminated use of symblic links on pinsn.c: use i960-pinsn.c
5061 - eliminated opcode.h: incorporates tables into i960-pinsn.c
5062 - moved 960-specific routines from i960-pinsn.c to i960-md.c
5063 - made disassembly interface identical to that in gdmp960.
5067 Wed Nov 28 21:32:48 1990 John Gilmore (gnu at cygint)
5069 * target.h: Allow targets to stack. Add target_has_memory,
5070 _registers, etc. Restructure memory access and "info files"
5071 to walk the target stack.
5072 * exec.c, core.c, inftarg.c, remote.c, remote-vx.c, remote-eb.c,
5073 target.c: Change tables to match target.h.
5074 * inflow.c (child_mourn_inferior): pop child_ops.
5075 (generic_mourn_inferior): Use new has_stack flag.
5076 * infptrace.c (child_xfer_memory): New memory regime.
5077 * inftarg.c (child_files_info): New "info files" regime.
5078 * remote-eb.c: New memory regime, new info files.
5079 * remote-vx.c: New memory regime, new info files. Now use
5080 separate targets for VxWorks attachment to machine, and
5081 actually running a process under VxWorks, since one has
5082 stack & execution & regs and the other doesn't.
5083 * remote.c: New memory regime, new info files.
5084 * sparc-xdep.c (fetch_core-registers): New memory regime.
5085 * target.c: New routines and support for stacked targets,
5086 new memory regime, new info files regime.
5089 Generalize section handling for an arbitrary number of sections,
5090 including use of the new BFD (binary file) library.
5091 * gdbcore.h: Add struct section_table.
5092 * exec.c (build_section_table): Iterate all sections and
5093 record what gdb needs to know about them.
5094 (exec_command): Use it.
5095 (exec_xfer_memory): Use the table.
5096 (exec_files_info): Print the table.
5097 * core.c (core_file_command, core_xfer_memory, core_files_info):
5099 * source.c (find_source_lines): Use bfd_get_mtime.
5100 * dbxread.c: Quick changes to make it compile with new BFD.
5101 * utils.c (error): Avoid using bfd_error in generic routines.
5103 * core.c (core_fetch_registers): Get from the ".regs" section of
5105 * sparc-xdep.c (fetch_core_registers): Use the .regs info.
5107 * inferior.h (attach_flag): Export.
5108 * infcmd.c (run_command): use new target_create_inferior.
5109 * infrun.c (child_create_inferior): Don't return result.
5110 * Makefile.dist (VERSION): 3.91.4.
5112 Fri Nov 23 28:15:38 1990 John Gilmore (gnu at cygint)
5114 * breakpoint.c (bpstat_num): Handle breakpoints which have
5115 since been deleted, such as temporary breakpoints.
5116 infcmd.c (program_info): ditto.
5118 * core.c (core_file_command): Display the frame where the core
5123 * remote-vx.c (target_command): Merge in target command from
5124 targ-vx.c. A few other cleanups.
5126 * TODO, Projects: Lots more stuff to do...
5128 Fri Nov 23 18:15:38 1990 John Gilmore (gnu at cygint)
5130 Massive changes to wall off the remote-debugging interface
5131 behind a function vector. The port to handle VxWorks targets
5132 is also part of this.
5134 All files: Replace references to renamed functions,
5135 remove references to remote_debugging, remove references to
5136 have_include_file, have_core_file in favor of target_has_stack,
5137 target_has_memory, etc.
5139 * Modularize the breakpoint interface.
5140 breakpoint.h (BREAKPOINT_MAX): New define sets max length of
5141 a breakpoint instruction.
5142 breakpoint.c: struct breakpoint's shadow_contents now sized as
5144 (insert_breakpoints): Vector to target to install breakpoints.
5145 (remove_breakpoints): Vector to target here too.
5146 Remove REMOTE_SA_SPARC kludges and other remote_debugging.
5147 sparc-tdep.c (single_step): Use new breakpoint interface for
5148 the single-step breakpoints.
5149 mem-break.c (memory_insert_breakpoint, memory_remove_breakpoint):
5150 New file, contains routines to insert and remove breakpoints by
5151 reading out the old contents and later replacing them. This is
5152 how ptrace breakpoints work, and many remote systems as well.
5154 * tm-vxworks68.h: New config file, overrides a few things for
5155 Wind River's preferences.
5157 * target.h: New file, for transfer vector used to talk to the
5158 inferior (child, attached, core, exec, remote, etc). All accesses
5159 to the thing being debugged should come through these vectors.
5160 target.c: New file, routines to handle transfer vector.
5161 (various files): Add transfer vectors XXX_ops for the various
5162 targets and pseudo-targets (core files, etc) we support.
5164 * breakpoint.c (bpstat_stop_status): Further explorations of
5165 watchpoints and why things don't work all the time.
5166 (bpstat_alloc): New fn to allocate a bpstat and chain it.
5168 * config.gdb: Only add "source ${srcdir}/.gdbinit" to
5169 the local gdbinit if it doesn't already have it.
5171 * core.c (core_ops): add and install.
5172 Allow core debugging without exec file.
5174 * dbxread.c (free_and_init_header_files): Merge two fns.
5175 (end_symtab): Free named symbol table when a new version comes in.
5176 (read_dbx_symtab): Relocate all kinds of symbols with base
5177 address. First step toward handling different text, data, bss
5179 (add_file_addr_command): Renamed add_file_command.
5180 (add_file_command): Vector to remote handler.
5181 Add "load" as an alias for "add-file" command.
5183 * defs.h: Allow "volatile" to be used in non-ANSI; use it for
5184 non-returning functions.
5186 * exec.c: Add exec_ops, and push it as a target when an exec
5189 * infcmd.c (run_command): Pass executable file name and arg list
5190 separately when starting an inferior. Permit "run" when no exec
5191 file is specified, for VxWorks.
5192 (detach_command): Move to child_detach in inftarg.c.
5194 * inftarg.c: New file. Unix-child-specific routines, and the
5195 child_ops structure.
5197 * inferior.h (registers): Export "registers" as the way for
5198 target dependent register handlers to find gdb's local copy of
5199 the registers. Rename "stop_after_attach" to "stop_soon_quietly"
5200 since it is now used by places that want wait_for_inferior to
5201 handle the grunge but want to see every trap from the inferior.
5203 * inflow.c (create_inferior): Pull out, and merge into infrun.c.
5204 Eliminate remote_debugging hooks in terminal handling.
5206 * infrun.c: Replace start_inferior with child_create_inferior.
5207 Move all the hair of Unix shells and ptrace idiosyncracies into
5208 child_create_inferior, so remote handlers don't have to deal.
5209 Remove running_in_shell. Rename stop_after_attach to
5210 stop_soon_quietly, and use it in a few other places where we want
5211 to just call wait_for_inferior and get control back on the first
5212 trap. trap_expected now never takes a value > 1.
5213 (init_wait_for_inferior): Initialize static vars when a new
5216 main.c (gdbinit): Add new hook for .gdbinit file name, let
5217 it be overridden by config files as GDBINIT_FILENAME.
5218 (DEFAULT_PROMPT): Add new hook for overriding (gdb) prompt.
5219 Both of these are used for VxWorks gdb.
5221 mcheck.c: rename include file "gmalloc.c" to avoid problems
5222 with system include file "malloc.c".
5224 param-no-tm.h: New include file, same as param.h but does not
5225 include the default "tm.h" file. This is used in files where
5226 the target is known, e.g. remote-eb.c or sparc-xdep.c.
5228 param.h: Now just a shell that includes tm.h and param-no-tm.h.
5230 remote-vx.c: New file, VxWorks remote debugging support. Uses
5231 RPC routines that are shared with the target system, in directory
5234 remote.c: Vectorize remote interface.
5236 source.c: Globalize source_path, and make an alias "l" for "list"
5237 since we now have the "load" command.
5239 sparc-xdep.c: Use new param-no-tm.h.
5241 symmisc.c (free_named_symtab): Add new function from Wind River.
5242 However, ifdef it out for now while we think about what it should
5245 tm-sun3.h, xm-sparc.h, xm-sun3.h, xm-symmetry.h: Move
5247 the xm- file, and change its name to CHILD_PREPARE_TO_STORE, since
5248 non-Unix-children handle this with their own code in the target
5251 Makefile.dist: Roll version to 3.92.3. Add vx-share stuff to
5252 source and target lists. Add vx-share to default list of include
5253 directories. Add new files to src and target lists: mem-break,
5254 target, inftarg, remote-eb, remote-vx, targ-vx. Be sure the
5255 ${srcdir} versions of munch and createtags are used.
5257 * valops.c (find_function_addr): Split out of call_function.
5258 (call_function_by_hand): Rename call_function; this function
5259 calls functions in the target by laboriously patching the target
5260 word-by-word with the right stack, args, regs, etc.
5263 Mon Nov 5 17:29:10 1990 John Gilmore (gnu at cygint)
5265 Handle AMD 29000 a bit better.
5267 * remote-eb.c (readchar): Mask received char log to make it readable.
5268 (remote_start): Pass arguments down to executing program.
5269 Make startaddr unsigned.
5270 infrun.c (start_inferior): Accept args, pass them to
5272 infcmd.c (run_command): Pass args down to start_inferior.
5274 * tconfig/am29k-aout, tconfig/am29k-coff: New files specifying
5275 the target object file format.
5276 tm-29k.h: Pay heed to COFF_ENCAPSULATE.
5278 * am29k-pinsn.c (print_insn): Print 0x on hex numbers in disassembly.
5279 am29k-tdep.c (examine_prologue): Better checking of function prefixes.
5281 Sun Oct 7 18:20:45 1990 John Gilmore (gnu at cygint)
5283 * Makefile.dist (VERSION): Roll version to 3.91.9 and freeze.
5284 * TODO: We did a few things, we have more to do though.
5286 * xm-sparc.h (CLEAR_DEFERRED_STORES): Define.
5287 * inflow.c (inferior_died): Clear deferred stores.
5289 * Debug problems with dummy frames and calls to the inferior.
5290 * tm-sparc.h (PUSH_DUMMY_FRAME, POP_FRAME): Move to sparc-tdep.c.
5291 * sparc-tdep.c (do_restore_insn): Simplify.
5292 (sparc_frame_find_saved_regs): Simplify and fix what we find.
5293 (sparc_push_dummy_frame): Simplify and fix what we push.
5294 (sparc_pop_frame): Slightly more hair here, deciding whether
5295 we are restoring a saved PC or returning to a return address in %i7.
5296 * sparc-xdep.c (read_inferior_registers): Debug if valid reg is read.
5298 * utils.c (xmalloc, xrealloc): Return type depends on __STDC__.
5299 * symtab.h (xmalloc): ditto, for obstack_chunk_alloc.
5300 * obstack.h (chunkfun): ditto.
5301 * defs.h (xmalloc, xrealloc): ditto
5303 * utils.c (quit): Grab the terminal from the child if necessary.
5305 * inflow.c (term_status_command): Rename to term_info, change
5308 * sparc-pinsn.c (print_insn): Disassembly prefers real instructions.
5309 (is_delayed_branch): Speed up.
5310 * sparc-opcode.h: Add ALIAS bit to aliases. Fix up opcode tables.
5311 Still missing some float ops, and needs testing.
5313 * Support for input and output radixes other than base 10
5314 * defs.h (input_radix, output_radix): Declare.
5315 * expread.y (yyparse, parse_number): Handle changes of input
5316 radix, and ambiguous names-or-numbers in radixes >10.
5317 * printcmd.c (print_scalar_formatted): Print formatted hex
5318 numbers in varying column widths.
5319 * valprint.c (val_print): Use output_format to print scalar ints.
5320 (set_input_radix, set_output_radix, set_radix): Create.
5321 (set_output_radix): Set output_format from output_radix.
5322 (_initialize_valprint): add `set radix' but leave the others off.
5324 * main.c (execute_command): Let stupid questions be turned off.
5325 (_initialize_main): Handle "set stupidity", etc.
5327 * main.c, inflow.c, inferior.h, frame.h, command.c, defs.h,
5328 sparc-pinsn.c, sparc-xdep.c, value.h, valops.c, values.c: Lint.
5330 Tue Oct 2 11:20:02 1990 John Gilmore (gnu at cygint)
5332 * TODO, Makefile.dist, ChangeLog: Freeze for 3.91.8 release.
5333 bfd stuff is still screwed up, but with some manual work, it
5336 * breakpoint.c (bpstat_do_actions): Start over if a command
5337 proceeds the inferior, since the inferior will have stopped and
5338 will need to have its new stop-actions taken care of.
5340 * dbxread.c (read_struct_type): Expression gives Sun3 4.0.3
5341 compiler fits, simplify it.
5343 * gdb.texinfo (directory command): Doc new dir command.
5344 source.c (directory_command): "dir" now puts things on the front
5345 of the path, moves dups up front, and handles multiple names
5346 on the command line, inserting each one in order. It also
5347 blows away cached line and full_filename info.
5349 * stack.c (backtrace_command): Skip "more stack frames follow"
5352 * Change #ifndef HAVE_VPRINTF to #define MISSING_VPRINTF in
5353 xm-convex.h, xm-hp300bsd.h, xm-isi.h, xm-merlin.h, xm-news.h,
5354 xm-np1.h, xm-pn.h, xm-pyr.h, xm-symmetry.h, xm-umax.h, xm-vax.h.
5355 The only odd one was Gould NP1, which had defined vprintf to
5358 * Merge Ted Goldstein <tedg@Eng.sun.com>'s changes for epoch.
5359 printcmd.c (print_command_1): Pass 'inspect' flag down as a global
5360 variable, inspect_it.
5361 valprint.c (print_string, val_print): Use the global inspect_it
5362 to indicate whether to print in Epoch style or normal style.
5364 Mon Oct 1 23:55:26 1990 John Gilmore (gnu at cygint)
5366 * printcmd.c (call_command): add an alias for the "print" command
5367 which runs expressions and doesn't print the result if void.
5368 (print_command_1): implement it.
5370 * command.c: Remove #if 0'd code. Initialize all the fields
5371 in add_cmd (). Rename do_nothing_command to
5372 not_just_help_class_command, and make it externally visible.
5373 command.h: add user_commands to struct.
5374 * main.c (define_command): Don't overload c->function with a char
5375 string as well as a function pointer.
5377 * eval.c (evaluate_subexp): Reinstall tiemann changes to
5378 calling convention of value_struct_elt () that got dropped in
5381 * tm-sparc.h (FRAME_FIND_SAVED_REGS): move to sparc-xdep.c.
5382 sparc-tdep.c (sparc_frame_find_saved_regs): ditto.
5384 * tm-sparc.h (POP_FRAME): replace some constants with defines.
5386 * sparc-xdep.c (store_inferior_registers): defer stores to regs
5387 until a good time (e.g. when we are about to run the child),
5388 saving ptrace calls.
5389 * infrun.c (proceed): handle DO_DEFERRED_STORES.
5390 * tm-sparc.h: define DO_DEFERRED_STORES.
5392 * sparc-xdep.c (store_inferior_registers): when storing float
5393 registers, don't store stack regs too. When storing the SP,
5394 however, DO store the stack regs too. This fixes a bug in which
5395 the dummy frame is not recognized when a call_function finishes,
5396 because its frame pointer (in the stack regs) was never
5398 (read_inferior_registers): Mark WIM and TBR and FPS and CPS valid
5399 even though we don't know how to read them from an inferior.
5400 valops.c (call_function): Comment about storing SP.
5402 * infrun.c (save_inferior_status): Save away the original bpstat
5403 chain so it can be restored later. Install the copied version for
5404 use by whoever saved the status. It will be blow away by
5405 restore_inferior_status, and the original chain restored. This is
5406 important for people who have pointers into the original.
5408 * breakpoint.c, command.h, copying.awk, dbxread.c, defs.h,
5409 findvar.c, frame.h, obstack.h, obstack.c, inflow.c, value.h,
5410 main.c, printcmd.c, sparc-tdep.c, symtab.c, valprint.c: lint
5413 Fri Sep 28 20:32:46 1990 John Gilmore (gnu at cygnus.com)
5415 * Makefile.dist: Roll version to 3.91.8. Add bfd.h and bfdconfig.h
5416 temporarily to the makefile. Add am29k-opcode.h and WHATS.NEW.
5417 Add stuff.c and kdb-start.c to the OTHERS list for tar files.
5419 Fri Sep 28 19:12:12 1990 John Gilmore (gnu at cygint)
5421 * Merge Mike Tiemann's multiple inheritance changes from Sun.
5422 Store the baseclasses in a type struct starting from array element
5423 0 rather than from the unusual array element 1.
5425 dbxread.c: the above.
5426 (virtual_context): Add
5427 Read new debug information about which virtual function table
5428 a virtual function is from, and store it in fn_field.fcontext.
5430 symtab.h: Add fcontextt. Fix baseclass indices. Typo in
5431 TYPE_FN_FIELD_STATIC_P.
5433 symtab.c: the above.
5434 valops.c: the above. Handle pointer casts of object *'s.
5435 (search_struct_method): Add.
5436 (value_struct_elt): First arg is now a pointer to a value, and is
5439 valprint.c: the above.
5440 values.c (value_virtual_fn_field): Add type arg. Handle
5441 offsetting to the proper object when calling virtual fns.
5443 (baseclass_addr): Add valuep arg.
5445 * README: Document the current state of BFD config (missing).
5446 * TODO, ChangeLog, Makefile.dist: Roll version.
5447 * WHATS.NEW: Add summary of changes since 3.5.
5449 Thu Sep 27 16:23:12 1990 John Gilmore (gnu at cygint)
5451 * dbxread.c (read_struct_type): Clear bit vectors whenever
5453 symtab.c (B_CLRALL): define.
5455 * tm-sparc.h (STORE_RETURN_VALUE): Avoid clobbering types by
5456 using == rather than =. Huh... This fixes the dreaded problem
5457 wherein builtin_type_int becomes TYPE_CODE_FLT.
5459 * core.c (info_files): Show the inferior pid.
5461 * config.gdb: Avoid putting "dir" command into .gdbinit. GDB
5462 already knows how to look in the source directory.
5464 * Remove psymtab hair from many places. Remove duplicated code
5465 for searching symbol tables. Hide psymtabs from most places.
5466 Make it fast to get from a psymtab to its symtab.
5468 blockframe.c (blockvector_for_pc): Remove psymtab hair.
5469 coffread.c (psymtab_to_symtab): Rename to psymtab_to_symtab2.
5470 mipsread.c (psymtab_to_symtab): Rename to psymtab_to_symtab2.
5471 dbxread.c: export psymtab_to_symtab, make it work if called N times.
5472 (psymtab_to_symtab): Rename to psymtab_to_symtab2. Initialize
5473 new symtab completely. New psymtabs get symtab pointer
5474 initialized to zero. Remove MI warning printf.
5475 symtab.h: Comments. Add psymtab to symtab pointer.
5476 (PSYMTAB_TO_SYMTAB): New macro.
5477 symtab.c: use PSYMTAB_TO_SYMTAB. Add psymtab_to_symtab and export it.
5478 source.c: use PSYMTAB_TO_SYMTAB. Remove symtab version and
5480 stack.c (backtrace_command): Avoid pre-pass to read symbols, if
5482 (print_frame_info): Avoid special-casing symbols that have not yet
5485 * source.c (open_source_file): Quick path if we have already
5486 located the source file by its full name.
5488 * symtab.c (lookup_symbol): Use find_pc_symtab rather than
5489 find_pc_psymtab. When a name is found in the misc function
5490 vector, search the symbol table for its mangled name, not the
5491 name that the user typed.
5493 * bfd.h: Fix missing comment terminators, make #endifs match.
5495 * valarith.c (value_less): Handle unsigned int comparisons.
5496 Add FIXME about pointer compares, which assume host and target
5497 pointers are the same.
5499 * command.c (do_nothing_command): lint
5500 dbxread.c: lint. Remove sort_syms. Document C++ visibility info,
5501 fix comments on debug symbol format for visibility. Actually set
5502 visibility of symbols.
5503 main.c (echo_command): lint; use <readline/history.h>.
5504 tm-sparc.h (FRAME_FIND_SAVED_REGS): lint
5505 obstack.h (_obstack_blank): Rearrange pointer math to avoid
5506 pointing past end of allocated memory; saber complains.
5507 obstack.h: Declare the external functions that we use.
5508 valarith.h: use <string.h>
5509 solib.c (solib_add): lint.
5511 Fri Sep 21 17:05:19 1990 John Gilmore (gnu at cygint)
5513 * main.c (initialize_main): Default info_verbose to off, now that
5514 symbol reading is fast.
5515 (quit_command): Avoid clobbering exec_bfd while quitting.
5517 * Initial BFD (binary file diddling library) merger:
5518 coffread.c: Change AOUTHDR to struct exe_hdr.
5520 core.c: initialize initialized data at compile time.
5521 (core_file_command): Move from coredep.c, convert to bfd.
5522 (xfer_core_file): Convert to bfd.
5523 exec.c (exec_file_command): use bfd routines.
5525 mips-tdep.c: Remove exec_file_command and friends.
5528 * coredep.c: (fetch_core_registers) Convert core_file_command to
5529 fetch_core_registers.
5530 mips-xdep.c, sparc-xdep.c, sun3-xdep.c: ditto.
5532 * utils.c: (error): Bogus crap, FIXME, to print bfd errors.
5533 (my_bfd_read): More bogosity, which I don't think we call.
5534 (program_name): Remove this atrocity asap!
5536 Wed Sep 19 13:36:41 1990 John Gilmore (gnu at cygint)
5539 values.c: allocate_repeat_value was not clearing the
5540 optimized_out field.
5541 (value_static_field): minor stylistic fix (wrong macro was used).
5542 valops.c (value_struct_elt_for_address): didn't work for C++
5545 * signame.c (_initialize_signame): Initialize signal names once.
5547 * breakpoint.h, command.c, copying.awk, defs.h, environ.c,
5548 exec.c, frame.h, infcmd.c, inferior.h, main.c, munch, sun3-xdep.c,
5549 symtab.h, tm-29k.h, valprint.c, value.h, values.c: Lint.
5551 * remote-eb.c: Support user-settable baud rates on the serial port.
5553 * tm-sun3.h (PREPARE_TO_STORE): fix typo.
5555 Fri Sep 14 13:28:29 1990 John Gilmore (gnu at cygint)
5557 * tconfig/sun3os4: Remove warning about native assembler,
5558 since it also occurs in the xconfig file.
5560 * findvar.c (registers): Allocate some slop after `registers'
5561 to prevent stray accesses from trashing the next variable.
5563 * tm-68k.h (REGISTER_BYTES): Allocate the right number of bytes
5564 on the sun-3, by changing the #ifdef from `sun3' (which is not
5565 defined by cc) to `sun'. Symptom was trashed builtin_type_XXX
5566 vars, which happened to follow `registers' in the executable.
5568 * readline/history.c (history_search): Heed gcc-2's advice
5569 and parenthesize && inside ||).
5571 * am29k-opcode.h, am29k-pinsn.c, am29k-tdep.c, remote-eb.c,
5572 tm-29k.c: Insert FSF copyright headers.
5574 * remote-eb.c: Better comments.
5576 * Makefile.dist: Update to 3.91.6.
5577 * TODO: note PREPARE_TO_STORE problem.
5579 Thu Sep 13 09:52:33 1990 Jim Kingdon (kingdon at cygint)
5581 * stack.c (frame_info): Only use FRAME_FIND_SAVED_REGS if defined.
5583 * remote.c: Wrap the whole file in #if !defined (SPECIAL_REMOTE).
5585 * infrun.c (wait_for_inferior, at end): Don't set up
5586 prev_* if the inferior no longer exists.
5588 * inferior.h (CALL_DUMMY_LOCATION): New macro, to replace
5589 CANNOT_EXECUTE_STACK.
5590 valops.c (call_function): Use it.
5592 * tm-convex.h: Add CALL_DUMMY_LENGTH for use by PC_IN_CALL_DUMMY.
5594 * inferior.h (PC_IN_CALL_DUMMY): New macro.
5595 infrun.c (wait_for_inferior, 2 places): Use it.
5597 * values.c (value_being_returned): Only use
5598 EXTRACT_STRUCT_VALUE_ADDRESS if defined.
5600 * Move PREPARE_TO_STORE from xm-sun3.h to tm-sun3.h to do the
5601 right thing for remote-eb.c.
5603 * sun3-xdep.c: Remove extraneous call to remote_store_registers.
5604 * sun386-xdep.c, hp300hpux-xdep.c, sparc-xdep.c: Ditto.
5606 * blockframe.c: Put get_frame_saved_regs inside #if !defined
5607 (FRAME_FIND_SAVED_REGS).
5609 * findvar.c ({fetch,store}_registers): Check for
5610 REMOTE_{FETCH_STORE}_REGISTER macro.
5612 * findvar.c (get_saved_register): Add argument lval and
5613 change meaning of argument addr.
5614 findvar.c: Change calls to get_saved_register to reflect
5615 new calling convention.
5616 valops.c (value_assign): Use get_saved_register instead of
5617 find_saved_register.
5619 Sun Sep 2 12:40:20 1990 Jim Kingdon (kingdon at cygint.cygnus.com)
5621 * coffread.c (read_one_sym): Make temp_aux an AUXENT, not
5622 an (uninitialized) pointer to one. Use "&" when passing it
5625 Fri Aug 31 22:57:54 1990 Jim Kingdon (kingdon at cygint.cygnus.com)
5627 * coffread.c (getfilename): Use DGUX x_offset and x_name if
5630 * coffread.c (symbol_file_command): Put semicolon after
5632 Put safe_to_init_tdesc_context in #if defined (TDESC).
5633 Put #ifdef TDESCs in 1st column for non-ANSI cpp's.
5634 coffread.c: #include <sys/stat.h>.
5635 (read_coff_symtab): Typo: in_source_files -> in_source_file.
5636 Add missing ')' in check for "lc%" and friends. Remove
5638 Declare read_one_sym() at top of file.
5639 (read_file_hdr): Put in extra #ifdefs so MC68MAGIC and
5640 MC68WRMAGIC can have the same value without causing a duplicate
5643 Thu Sep 13 15:55:36 1990 John Gilmore (gnu at cygint)
5645 * Allow a Makefile to be built without building the
5646 tm and xm file links that screw up builds in subdirectories.
5647 This is done with `config.gdb none', then you can do things
5648 like `make gdb.tar.Z'.
5649 * tconfig/none: Config file for no target system
5650 * xconfig/none: Config file for no host system
5651 * config.gdb: If no TM or XM files are called out by the
5652 host or target file, don't make links for them.
5654 * cplus-dem.c: Add documentation.
5656 * dbxread.c (read_ofile_symtab): Turn a fatal error into a
5657 simple error, so the user's gdb doesn't crash due to some object
5658 file problem (e.g. somebody is rebuilding the file out from under
5661 * printcmd.c (print_address_symbolic): demangle the symbol.
5663 * Makefile.dist (OTHERS): Remove tdesc-lib because it has
5664 Motorola copyrights in it. Make "make gdb.tar.Z" work.
5665 (alldeps.mak): sort and uniq all results from this; duplicates
5666 hose gdb.tar.Z link building. Remove RCS files from
5667 tconfig and xconfig. Add config files for sun386. Add
5668 a few odd files to OTHERS and HFILES.
5670 Mon Sep 10 21:20:24 1990 John Gilmore (gnu at cygint)
5672 * Makefile.dist: Pull solib.c to tconfig/sun?os4.
5673 Roll version number to 3.91.5. Make lint work in bindir.
5675 * README: Document cross-debugging and new file structure.
5677 * blockframe.c: Lint. Include "value.h" to declare read_register.
5678 (find_pc_partial_function): remove duplicate line.
5680 * command.h: Lint. Declare error_no_arg and dont_repeat.
5682 * tm-news.h: Remove inadvertently duplicated stuff.
5684 * mipsread.c: Remove cache_pc_function stuff, now done cleanly.
5685 Clean up usage of misc_function_type. Declare some CORE_ADDRs.
5687 * config.gdb: Allow `config.gdb host target' form. Clean
5688 up previous change that printed bogus messages when you just said
5691 * core.c: #include "command.h" for lint.
5694 * main.c: Remove some casts of enums. Lint.
5701 * printcmd.c (initialize_printcmd): Fix thinko in inspect cmd.
5703 * sparc-tdep.c (isannulled): Take instruction as parameter, don't
5704 read it from memory. This will allow us to save ptrace calls
5705 eventually. Changed caller single_step too.
5707 * sparc-xdep.c (fetch_inferior_registers): Avoid reading regs
5708 that we aren't going to use, saving many ptrace calls, especially
5709 when watchpointing or single stepping. Use some #define's for
5711 (store_inferior_registers): Ditto.
5712 (core_file_command): Use some #define's for constants.
5714 * tm-sparc.h: Add #define's for some register numbers, so we
5715 can eliminate the use of random constants in sparc-xdep.c.
5717 * stack.c (frame_command, print_frame_info, up_command,
5718 down_command) Remove frame_changed, since it
5719 causes a bug and doesn't seem to do anything useful. In some
5720 places it was used as a flag, in others as a stack level (?).
5722 * utils.c: Use MISSING_VPRINTF rather than HAVE_VPRINTF, so the
5723 default is to use the portable (vprintf) version rather than the
5725 * xm-news.h (MISSING_VPRINTF): Add.
5727 * valprint.c (val_print): Demangle fancy vtbl printouts. Lint.
5729 Sat Sep 8 00:24:12 1990 John Gilmore (gnu at cygint)
5731 * Remove stuff that forces -Bstatic linking of gdb, and warnings
5732 about linking debugged programs -Bstatic in the sun?os4 config
5733 files in tconfig and xconfig subdirectories.
5735 * main.c (main): Remove unreached exit(0) now that we exit
5738 * Create TODO file for online bug list. There are too many
5739 "little" bugs to keep track of on paper.
5741 * Change Projects file to refer to bug-gdb@cygnus.com
5742 rather than kingdon@ai.
5744 Fri Sep 7 23:35:15 1990 John Gilmore (gnu at cygint)
5746 * Makefile.dist (VERSION): 3.91.4 now.
5748 * symtab.c (init_misc_bunches): Rename from init_misc_functions.
5749 (condense_misc_bunches): Add sanity check that misc_count is
5750 the same as the number of symbols in the bunch.
5752 * coffread.c: rename init_misc_bunches. Pass an argument
5753 to condense_misc_bunches (a zero).
5755 * dbxread.c (partial_symbol_file_read): Call init_misc_bunches
5756 every time we are called; don't rely on our caller to do it.
5757 (add_file): Remove call to init_misc_bunches.
5759 * mipsread.c: Only warn, don't error, if unknown symbol types.
5760 This keeps an old gdb from falling on its face if it sees newly
5761 extended symbol info. Rename init_misc_bunches.
5763 Fri Sep 7 22:58:15 1990 John Gilmore (gnu at cygint)
5765 * Merge in changes from Per Bothner for DECstations and other
5766 MIPS stuff. The rest is Bothner speaking:
5768 The next message is a merger of Alessando Forin's mips port with
5769 mine. I've tried to use my good if biased judgment to get
5770 the best of both. It *does* need testing.
5772 Some of the changes are general, *not* mips-specific.
5775 Didn't believe in little-endian bit order.
5776 There are still inconsistencies about whether flags
5777 like BITS_BIG_ENDIAN are integer (#if ...) or
5778 boolean (#ifdef ...). I tried to paper over them.
5780 dbxread.c,coffread.c,mipsread.c,symtab.c,symtab.h:
5781 Moved some misc_function code that was common to
5782 {dbx,coff,mips}read.c to symtab.c.
5783 In the process, I think I cleaned things up a bit.
5784 At the same time, moved obsavestring and obconcat to symtab.c.
5787 Removed obsolete condense_addl_misc_bunches (use
5788 condense_misc_bunches(1) instead).
5791 Needed to include <sys/dir>, at least on DECstations.
5793 valops.c, mips-tdep.c, tm-mips.h:
5794 Added PUSH_ARGUMENTS macro to support funny argument-pushing
5795 conventions (when STACK_ALIGN is insufficient).
5796 Needed on mips, where doubles need 8-byte alignment,
5797 but ints only need 4.
5800 Removed cruft that was not being used.
5801 Merged in many fixes (most from Frank Yellin, fy@lucid.com).
5804 Print $ before register-names (I think that makes things a little
5806 Never print two instructions, even if one delays.
5807 Removed hex-disassemble set_cmd. (This is not mips-specific,
5808 so I think the argument is whether it is generally worthwhile or not.
5809 I'm inclined to think not, given how easy it is to
5810 convert between radixes in gdb.)
5813 This is basically Alessando's code.
5814 It doesn't use obstacks; I changed it to use obstacks
5815 in a few minor places where using malloc causes a
5816 memory leak. (Probably, more places could/should be changed.)
5817 I added record_misc_function where it was missing.
5818 In symbol_file_command and add_file_command, I tried
5819 to make the code consistent with more recent versions.
5820 Minor sylistic changes in parse_procedure.
5821 Make a .gdbinfo. psuedo-symbol point back to the real
5822 procedure symbol (using the isym field).
5825 This is basically from my port, but with a lot of details
5826 and a number of routines merged in from Alessando's version.
5827 I basically used my code "raw" backtrace (use heuristics
5828 from the actual code, rather than symbol table info) - though
5829 the idea is Alessandro's. I feel my code is a little cleaner
5830 here, particularly in being a little more flexible, such as being
5831 able to handle gcc-produced code (which it now can).
5832 It also doesn't do frame caching (which is not useful
5833 more recent gdb versions).
5834 I also used my code for push_/pop_dummy, more or less.
5835 I tried to incorporate AF's code for testing sigtramp
5836 while backtracing; I probably got it wrong.
5837 Added mips_print_register, which tries to scrunch as much
5838 information as possible on a screen...
5839 Removed the skip-prologue set_cmd. As with hex-disassemble (see
5840 under mips-pinsn.c), I don't see anything mips-specific here,
5841 and I don't see it being all that useful anyway.
5844 Added a $fp psuedo-reg distinct from $fp (nice for gcc).
5845 Use more register names (rather than hard-cases numbers).
5847 Thu Sep 6 18:33:15 1990 John Gilmore (gnu at cygint)
5849 * Hack up 3.90.11 changes:
5851 * Makefile.dist (depend): parameterize $(GCC).
5852 Add solib.c and solib.o.
5853 (readline): Fix vpath for both absolute or relative SRCDIR.
5855 * blockframe.c: Fix from Schaefer@asc.slb.com for shared libs.
5856 Also, let the part I didn't understand at least compile so
5857 I can test the rest. FIXME.
5859 * dbxread.c: Fix thinko using strcmp.
5860 (init_psymbol_list): declare static.
5861 (partial_symbol_file_open): Comment cleanups better, avoid
5862 cleaning up the string table since the caller will do that.
5863 Move the stat for mod time into symbol_file_command, temporarily.
5864 (There should be a mod time for each symbol file, eventually,
5865 to control its rereading. FIXME.)
5867 * infptrace.c (PT_WRITE_D): use same value as PT_WRITE_I for
5868 SunOS, which gives error for shared libs otherwise. (From
5869 Schaefer, probably FIXME needs work for portability.)
5871 * solib.c: Move #include "param.h" to work.

5902 Put parens around gcc_p in expansion.
5904 Thu May 24 15:44:51 1990 Jim Kingdon (kingdon at mole.ai.mit.edu)
5906 * utils.c (lines_to_list): Return 10 if lines_per_page == 0.
5908 Wed May 23 16:36:04 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5910 * Changes for Sun shared libraries:
5911 blockframe.c (find_pc_partial_function): If a non-text symbol
5912 is found, set *address = pc - FUNCTION_START_OFFSET.
5913 breakpoint.c (insert_breakpoints) [DISABLE_UNSETTABLE_BREAK]:
5914 Disable breakpoints instead of giving an error.
5915 source.c (select_source_symtab): Initialize cs_pst.
5916 symmisc.c: Call CLEAR_SOLIB if defined.
5917 symtab.h: Make text{low,high} CORE_ADDR not int.
5918 (psymtab): New field addr.
5920 dbxread.c: Move DECLARE_FILE_HEADERS outside functions.
5921 (record_misc_function): Give correct type for N_DATA symbols.
5922 (condense_misc_bunches): do "misc_function_count = j" regardless
5924 Take code which is shared between symbol_file_command and
5925 add_file_command and put it into partial_symbol_file_{open,read}.

5932 Tue May 22 17:43:03 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5934 * infcmd.c: Change cont_command to continue_command and "cont"
5937 Mon May 21 14:41:41 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5939 * breakpoint.c (enable_breakpoint): Get value of watchpoint.
5941 * defs.h [sparc]: Use <alloca.h> regardless of __GNUC__.
5943 * values.c (USE_STRUCT_CONVENTION): Check for structures of
5944 size 1,2,4,8 rather than size < 8.
5946 * dbxread.c (dbx_lookup_type): Do f->length *= 2 as many times
5947 as necessary, not just once.
5949 * sparc-opcode.h: Add a bunch of new opcodes which Sun as supports.
5951 Thu May 17 15:04:09 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5953 * {t,x}m-sun386.h, sun386-xdep.c, {x,t}config/sun386
5955 * tm-news.h: Add CALL_DUMMY_*.
5957 * tm-68k.h: Remove duplicate comment at FRAME_FIND_SAVED_REGS.
5959 * config.gdb: In list_host, list_target, use ${i}, not $i.
5961 Tue May 15 21:27:12 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5963 * source.c (find_source_lines) [BROKEN_LARGE_ALLOCA]: Use xmalloc.
5965 * sparc-opcode.h: Change all store floating-point state register
5966 instructions to have the right match & lose fields.
5968 Sat May 5 12:39:18 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5970 * Makefile.dist: Move -I${srcdir} to GLOBAL_CFLAGS and pass
5972 config.gdb: If srcdir != ., create readline directory and
5973 copy a makefile into it.
5975 * wait.h, infrun.c: Change WRETCODE to WEXITSTATUS for
5976 consistency with POSIX.
5978 * breakpoint.c (bpstat_stop_status): Disable watchpoint
5979 when we exit its exp_valid_block.
5981 Tue Sep 4 11:46:46 1990 John Gilmore (gnu at cygint)
5983 * Makefile.dist: Bump version to 3.91.3.
5985 * Clean up handling of breakpoint commands (somewhat).
5986 Prompted by Tiemann bug report "cont 10" doesn't work any more.
5988 inferior.h: Add breakpoint_proceeded to inferior status struct
5989 and globals; save it and restore it.
5990 (clear_breakpoint_commands): Cleanup, remove old #define.
5992 infrun.c (clear_proceed_status): Set breakpoint_proceeded.
5993 (save_inferior_status, restore_inferior_status): handle it also.
5994 (proceed): Remove earlier code that set breakpoint_proceeded.
5995 It is now set only in clear_proceed_status.
5996 (clear_proceed_status): Cleanup, use bpstat_clear rather
5997 than clear_breakpoint_commands. No callers need the stop_bpstat
5998 between clear_proceed_status and proceed.
6000 infcmd.c: Add breakpoint_proceeded definition and comment.
6001 (cont_command, jump_command, signal_command): Move call to
6002 clear_proceed_status right next to call to proceed.
6004 breakpoint.c (bpstat_do_actions): Avoid clobbering our
6005 caller's argument while running down the chain of breakpoints.
6006 Use new variable "breakpoint_proceeded" to determine when
6007 a command that it executes moves the inferior past the
6009 (bpstat_clear): Handle NULL argument.
6010 (bpstat_clear_actions): Avoid useless call to
6011 breakpoint_auto_delete.
6012 (delete_breakpoint): Clean up bpstat's that are pointing to
6013 the deleted breakpoint from the stop_bpstat chain.
6014 (breakpoint_auto_delete): Simplify.
6016 * Clean up handling of EOF, error on stdin, etc. This was
6017 prompted by a network problem that caused gdb to go into an
6018 infinite loop filling up its malloc'd memory.
6020 main.c (return_to_top_level): Cleanup: call bpstat_clear_actions,
6021 not clear_breakpoints_commands, which is now gone.
6022 (main): If command_loop returns (e.g. from EOF on stdin), do
6023 a quit_command (looping back to command_loop if quit_command
6024 doesn't really quit).
6025 (command_loop): check result from command_line_input and
6026 exit if it returns NULL, rather than passing the NULL to
6028 (gdb_readline): Free malloc'd result space before returning
6031 * utils.c (query): Handle C-d to mean "yes", just as if the
6032 input was not a terminal. Also avoid infinite loop if EOF
6033 occurs in mid-input-line before newline. This allows
6034 query to be used at EOF on stdin with reasonable results.
6036 * infrun.c (proceed): Set breakpoint_proceeded.
6038 * values.c (value_as_long): Avoid infinite recursion for enums.
6039 (_initialize_values): Fix typo in help msg (kingdon).
6041 * Makefile.dist (RL_LIB): Use RL_LIB_DEP for dependencies,
6042 RL_LIB for linking. This allows -lreadline for linking
6043 and nothing for dependencies, once readline is a real library.
6045 * config.gdb: Jim Kingdon: give useful error message if the
6046 host or target type is not recognized.
6048 * defs.h (alloca): SPARC <alloca.h> does not declare alloca,
6049 it just defines it. Dumb, but deal with it.
6051 * Jim Kingdon suggests:
6052 in xconfig/sun3os4, CFLAGS should be XM_CFLAGS.
6054 Wed Aug 29 18:03:27 1990 John Gilmore (gnu at cygint)
6056 * Makefile.dist (VERSION): Bump version # to 3.91.2.
6058 * Clean up Bothner's changes.
6060 * blockframe.c (clear_pc_function_cache): New function.
6061 * blockframe.c: remake cache_pc_function_* static.
6062 * dbxread.c (symbol_file_command): remove references to
6063 cache_pc_function_* variables.
6064 * dbxread.c (read_struct_type): Use VOFFSET_STATIC.
6065 * printcmd.c: Avoid kludging a global variable (addressprint)
6066 to avoid printing the address of a string twice. Instead,
6067 pass the format letter 's' down low enough that it can be seen
6068 to avoid this problem.
6069 (print_formatted): Pass format arg to value_print.
6070 (restore_addressprint): Remove function.
6071 (do_examine): Avoid hacking addressprint, cleanups and such.
6072 (print_frame_args): Add a comment to a Bothner change.
6073 * symtab.h: define VOFFSET_STATIC and use it instead of "-1".
6074 * symmisc.c (free_all_symtabs): Call clear_pc_function_cache
6075 to wipe out the values cached in blockframe.c.
6076 * symtab.c (find_method): Add comment saying how big you must
6077 allocate to be "big enough". Per being terse again.
6078 * valprint.c (val_print): Handle format letter "s" to print
6079 strings without addresses. Add comment to vtbl printing code
6080 which casts with wild abandon. Rearrange reference-printing
6082 @0xaddr: value (print w/addressprint)
6083 value (print w/~addressprint)
6084 @0xaddr (parameter lists w/addressprint)
6085 or nothing (parameter lists w/o addressprint)
6087 Tue Aug 28 10:47:18 1990 John Gilmore (gnu at cygint)
6089 * Merge more changes from Per Bothner:
6091 Gdb's handling of TYPE_CODE_REF was so counter-C++ (and otherwise
6092 annoying) that I tried to improve it. Here are my suggestions.
6094 These patches all attempt to handle TYPE_CODE_REF (as in C++) better.
6097 Do automatic de-reference when taking the address of a reference.
6099 Don't deref_ref when printing parameter lists.
6101 More attempts at treating refernences properly.
6103 In val_print, if deref_ref==0, don't print dangling " = ".
6105 Add COERCE_REF macro, which de-references an REF.
6107 * Merge changes from Per Bothner:
6109 * Fixed (Sony news)-specific configuration problems.
6110 * Fixed other problems with using vanilla pcc and libc (enum problems;
6111 assumption that vsprintf exists).
6112 * Some major speed-ups (finc_pc_partial_function now caches a match;
6113 parsing avoids duplicate symbol_lookup calls).
6114 * Changed handling of baseclasses (no longer use baseclasses field
6115 of struct type, use the first n_baseclasses fields instead).
6116 * Various minor changes/fixes, most C++-related.
6119 Cache the most previous match from find_pc_partial_function.
6120 (Save both low and high ends of matching function's pc range.)
6121 This speeds up the loop of infrun.c:wait_for_inferior quite
6122 a bit, and makes step/next commands much zippier.
6124 Added an enum->int cast (otherwise, some compilers barf).
6126 No longer set baseclass offset to 0, since multiple
6127 inheritance now mostly works.
6128 Added a number of casts, to shut up compiler warnings
6129 (after stabs where made enums, not ints).
6130 When discarding a symbol table (in symbol_file_command),
6131 must clear the cache introduced in blockframe.c.
6132 Don't convert $vtbl_ptr_type to vtbl any more.
6133 Get rid of TYPE_BASECLASEES and baseclass_vec (see also symtab.h).
6134 Mask off sign bit emitted by g++ for virtual table offset.
6135 Set voffset to -1 (not 1) for static member functions.
6137 Changed parsing/lexing of names to avoid doing symbol lookup twice
6138 (once when lexing to determine symbol class, once for real).
6139 Now only call symbol_lookup once. Fields of 'this' win especially big.
6141 Subpress printing addr twice in the case of 'x/s addr'.
6143 lookup_basetype_type is no longer used.
6144 Add find_methods as recursive helper function to decode_line_1.
6145 This allows multiple inheritance to work.
6146 Also, once one or more matches has been found, do not look in
6147 base-classes. (Baseclass methods would be overridden, anyway.)
6149 Removed baseclasses array in struct type.
6150 Instead of using baseclasses[i], use fields[i-1].
6151 Added virtual_field_bits[i] to indicate if the i'th baseclass is virtual.
6152 Changed sign convention of voffset (previous was inconsistent).
6154 Some macros (CALL_DUMMY and relatives) were missing. Put them back.
6156 Used to assume existence of vsprintf. Re-written to not need it
6157 if HAVE_VPRINTF is undefined.
6159 typecmp was too pessimistic. Made it less so.
6161 Don't print space after address.
6162 If vtable points to a misc symbol (with 0 offset), print it,
6163 since that indicates the actual class of the object.
6164 Changed ype_print_derivation_info to use new inheritance
6165 scheme (without baseclasses vector).
6167 In value_primitive_field, fixed some bugs left over from previous set of fixes.
6168 Also, changes needed because TYPE_BASECLASSES were removed.
6170 REGISTER_U_ADDR didn't work for PC. Rewrote to use an array.
6172 Tue Aug 21 20:08:54 1990 John Gilmore (gnu at cygint)
6175 If there is no path set, and the symbols don't indicate what directory
6176 a file was compiled in, look in the current directory. But either
6177 a path or a known compilation directory will prevent this.
6180 Three independent bug fixes:
6181 * Remove the #if 0 block that breaks some stuff.
6182 * SunOS 4.1 fixed the promoted-parameter-wrong-addr bug in Sun C;
6183 adapt gdb to either SunOS 4.0.* or 4.1.
6184 * MAX_OF_TYPE and MIN_OF_TYPE thinko. By tedg@sun, I think.
6187 Instantiate the class T when looking for methods in it. (Tiemann@sun)
6190 (type_print) Demangle the name being printed.
6191 (type_print_base) Handle botched demangling without coredump (tiemann).
6194 (check_stub_method): Document routine.
6195 (tiemann) fix bug for no-arg functions
6196 Avoid clobbering beyond end of malloc'd storage.
6197 Terminate the argument list properly.
6199 Sat Aug 18 01:29:59 1990 Per Bothner (bothner@cs.wisc.edu)
6201 * Changes merged by John Gilmore:
6204 In breakpoint_1, use new print_address_symbolic instead
6205 of find_pc_partial_function. (This forces use of assembler-level
6206 addresses, and avoids misleading non-mangled source-level names.)
6208 Generalize ansi argument such that -1 means skip arglist totally.
6209 Removed global variable print_ansi_qualifiers (which made
6210 code non-reentrant), in favor of extra explicit arguments
6211 to internal routines.
6213 Add new helper function print_address_symbolic.
6214 Use find_pc_misc_function instead of find_pc_partial_function
6215 (since we want assembler-level symbols here).
6217 Print unknown function as just "f (...)", not "f (...) (...)".
6218 Use new fputs_demangled explicitly.
6220 Fixed a typing violation (problem: value.h cannot be imported
6221 without renaming many variable in this file).
6222 lookup_symbol: If no matching misc_func, look for a C++-mangled name.
6223 decode_line_1: Moved forward some never-reached code.
6224 Made decode_line_2 skip function prologues correctly.
6226 fputs_filtered should not demangle by default.
6227 Add new fputs_demangled to demangle on demand..
6229 Change value_struct_elt to use value_primitive_field (using recursive
6230 utility function search_struct_field). This allows foo.bar to work
6231 for multiple inheritance (so far only for data fields).
6232 Change check_field in the same way (recursive helper function
6233 to support multiple inheritance).
6234 (Note: there are more of these problems that I haven't fixed.
6235 Any code that says TYPE_BASECLASS (t, 1) is probably wrong.)
6236 value_of_this: 'this' symbol name is now just "this", note "$this".
6238 Don't print static members.
6239 Avoid printing "members of <type>" if there are none.
6240 Simplified type_print_derivation_info by merging duplicate code.
6241 Remove useless blank lines in type_print_base (ptype command).
6243 Added declaration of new routine value_primitive_field.
6245 Added value_primitive_field which is generalized version of
6246 value_field that can handle multiple inheritance (non-zero offsets etc).
6247 Re-implemented value_field to call value_primitive_field.
6249 Fri Aug 17 23:33:44 1990 John Gilmore (gnu at cygint)
6251 * infcmd.c -- insert else to avoid 'delete env' coredump when you
6252 delete the whole environment. Karl Berry reported the bug.
6253 * source.c - fix openp to avoid //'s in filenames, which
6254 trigger an Emacs bug causing it to not be able to find files
6255 when running gdb in a window.
6256 * dbxread.c - zap the #if 0 that botches the add-file code.
6257 It seems to work a lot better without all the code commented out.
6259 Fri Jul 20 16:58:46 1990 John Gilmore (gnu at cygnus.com)
6261 * Merge Tiemann's and Ted Goldstein's changes, detailed below,
6264 Tue Jul 17 19:34:33 1990 Ted Goldstein (tedg at golem)
6266 * Makefile - added a ${CFLAGS} to a couple of entries,
6267 added remote-sa.sparc.c
6268 * added remote.sa-sparc.c, a modification of remote.c
6269 which conducts a dialog directly with the SparcStation prom.
6270 * breakpoint.c, infrun.c, sparcdep.c added
6271 remote_insert_breakpoint(), and remote_remove_breakpoint()
6272 to breakpoint.c instead of directly writing breakpoint instructions.
6273 * sparcdep.c on remote_debugging,there is no need
6274 to remove signle step breakpoint instructions.
6275 * main.c added "-epoch" flag and "int epoch_interface" to main.c
6277 * printcmd.c - epoch interface sends lisp expressions to open up
6278 epoch windows on inspection.
6279 * valprint.c - added arrayprint, and addressprint and made adding
6280 format controls easier
6281 * wait.h added a couple of undef's because we were getting
6282 complaints about WSTOPSIG and WTERMSIG begin redefined.
6285 Wed Jul 4 05:27:51 1990 Michael Tiemann (tiemann at masham)
6287 * symtab.c (decode_line_1): Add support for handling method stubs
6288 in the type information.
6290 Tue Jul 3 09:39:18 1990 Michael Tiemann (tiemann at masham)
6292 * values.c (baseclass_addr): Run loop from INDEX+1 to
6293 N_BASECLASSES; otherwise, we can still get into a loop.
6294 @@ This should be restructured to use a cleaner search strategy.
6296 Sun Jul 1 12:28:51 1990 Michael Tiemann (tiemann at masham)
6298 * dbxread.c (define_symbol,read_type): Grok GNU C++'s new
6299 abbreviation "Tt" for tags which have the same name as their
6302 Fri Jun 29 01:03:46 1990 Michael Tiemann (tiemann at masham)
6304 * symtab.c (list_symbols): add ability to set breakpoints on all
6305 the functions which match a particular regular expression.
6307 Tue Jun 26 04:26:29 1990 Michael Tiemann (tiemann at masham)
6309 * cplus-dem.c (cplus_demangle): New parameter ANSI says whether we
6310 should print ANSI qualifiers (such as `const' and `volatile').
6311 All callers changed to call with ANSI == 1, except from
6312 `check_method_stub', which uses old-style syntax.
6314 * symseg.h (struct fn_field): Remove unneccessary `args' field.
6315 * symtab.h (TYPE_FN_FIELD_ARGS): Redefined.
6317 * values.c (check_stub_method): New function.
6319 * cplus-dem.c (do_type): Handle "long long" (encoded as 'x').
6321 * dbxread.c (read_type): Handle new GNU C++ method type stubs.
6322 * valprint (type_print_base): Ditto.
6324 * symtab.c (gdb_mangle_typename): New function.
6326 Tue Jun 5 00:18:43 1990 Michael Tiemann (tiemann at gzilla)
6328 * breakpoint.c (catch_command): New function. Provides a
6329 mechanism to set breakpoints based on catch clauses.
6330 (disable_catch): Similar, but disables breakpoints on catch
6332 (delete_catch): Similar, but deleted breakpoints on catch clauses.
6334 Sun Jun 3 22:54:08 1990 Michael Tiemann (tiemann at gzilla)
6336 * blockframe.c (blockvector_for_pc): New function.
6337 * blockframe.c (block_for_pc): Changed to call
6338 `blockvector_for_pc' and get the block itself.
6340 * stack.c (catch_info): New function. Prints info about
6341 exceptions which can be caught in the current frame.
6342 * stack.c (print_frame_label_vars): New function. Similar to
6343 `print_frame_local_vars'.
6344 * stack.c (print_block_frame_labels): Prints out labels that are
6345 defined in this frame. These labels are exceptions that can be
6348 * dbxread.c: Updated to handle N_CATCH symtab types.
6350 Thu May 3 22:10:00 1990 Michael Tiemann (tiemann at teacake)
6352 * valprint.c (everywhere): TYPE_NAME (TYPE) no longer comes in the
6353 form "struct ..." for GNU C++. Don't flush any part of TYPE_NAME
6354 when printing the type.
6356 Wed May 2 22:43:04 1990 Michael Tiemann (tiemann at teacake)
6358 * valprint.c (val_print): Use `baseclass_addr' to access the
6359 baseclasses pointed to via the derived class object at VALADDR.
6361 * values.c (baseclass_addr): New function. Casts derived pointers
6362 to baseclass pointers taking virtual baseclasses and multiple
6363 inheritance into account.
6365 Sat May 5 12:39:18 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
6369 Fri May 4 12:12:55 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
6371 * breakpoint.c (watch_command, bpstat_stop_status): Deal with
6372 exp_valid_block field correctly.
6374 * infrun.c (wait_for_inferior): When checking "don't even think
6375 about breakpoints" if stop_signal == SIGTRAP && trap_expected,
6376 also check step_resume_breakpoint.
6377 Insert breakpoints and continue (not step) if
6378 step_resume_break_address != NULL, even if another_trap.
6379 If trap_expected and we enter sigtramp, then set up a
6381 If trap_expected is set when we hit the step_resume_break,
6383 When calling resume and trap_expected says tell resume to step
6384 (2 places), also check step_resume_break_address.
6386 * infrun.c (wait_for_inferior): Don't set
6387 prev_{pc,sp,func_{start,name}} before calling wait ().
6388 Do set them after exiting loop.
6389 Move their declarations outside functions.
6390 (start_inferior): Initialize them.
6392 Thu May 3 00:15:11 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
6394 * infrun.c (wait_for_inferior, after check for trap_expected > 1):
6395 Restore old code which distinguishes between trap_expected and
6396 running_in_shell, just make the latter take any non-TRAP signal,
6399 * values.c (allocate_value): Zero VALUE_OPTIMIZED_OUT flag.
6401 * Makefile.dist (pinsn.o): Use PINSN_CC to compile.
6402 xconfig/3b1 (CC,PINSN_CC): Define.
