1 Mon Nov 18 17:45:18 1991 Fred Fish (fnf at cygnus.com)
3 * procfs.c: Move inclusion of defs.h to before param.h, as in
4 all the other source files that include both. This is required
5 to supply some typedefs that are used in files included by param.h.
7 * m68k-tdep.c (m68k_skip_prologue): Add generic m68k support for
8 skipping function prologues, ala the other cpu families (i386,
9 mips, m88k, etc). Add the ability to skip movm and fmovm
10 instructions in the prologues. Still needs support for profile
11 (-p compiled) prologue sequences (FIXME).
13 * tm-68k.h: Change SKIP_PROLOGUE macro to use the new generic
14 m68k prologue skipping function by default.
16 * tm-altos.h, tm-isi.h: Continue to use the old definition of
19 Mon Nov 18 15:12:45 1991 John Gilmore (gnu at cygnus.com)
21 * blockframe.c: Remove tdesc-related code. Default
22 FRAME_CHAIN_COMBINE if not defined.
23 * infrun.c: Remove tdesc-related code.
24 * m88k-tdep.c (frame_chain_combine, init_frame_pc): Remove copies
25 of defaultable things.
26 * tm-m88k.h: New file, common to all Moto 88k target configs.
27 Derived from tm-delta88.h.
28 * tm-delta88.h: Use it.
29 * xm-m88k.h: Common file for 88K hosts. Remove obsolete stuff.
30 * xm-delta88.h: Use it.
31 * tm-*.h: Remove FRAME_CHAIN_COMBINE macros, since all are
33 * coffread.c: Remove tdesc stuff.
34 * tconfig/delta88, tconfig/m88k: Remove tdesc stuff.
35 * xconfig/m88k: Rename tm-88k.h to tm-m88k.h.
37 Mon Nov 18 13:51:37 1991 Per Bothner (bothner at cygnus.com)
39 * source.c (open_source_file): If openp fails, try again
40 using just the base (non-directory) part of the filename.
41 This solves various annoying problems, such as when the
42 source was compiled with an absolute pathname - and the
43 source files have moved. Or if the source was compiled
44 using a relative pathname, it can be more convenient
45 to just specific the source directory to the dir command.
47 Mon Nov 18 00:04:41 1991 Fred Fish (fnf at cygnus.com)
49 * cplus-dem.c (munge_function_name): Add missing third arg to
50 instance of call to do_type().
52 * dwarfread.c: Changes to match new dwarf.h. Remove
53 AT_deriv_list, AT_loclist, AT_incomplete, AT_const_data,
56 Sun Nov 17 16:20:53 1991 Michael Tiemann (tiemann at rtl.cygnus.com)
58 * symtab.h (struct type): Moved C++-specific fields into new type
59 `struct cplus_struct_type'. Now takes 10% less memory. Many
61 * symtab.c (init_type): Don't set fields belonging to
62 TYPE_CPLUS_SPECIFIC unless TYPE is TYPE_CODE_STRUCT.
63 * buildsym.c (read_type): Allocate TYPE_CPLUS_SPECIFIC for
65 (read_struct_type): Ditto. Also, add comments about how we can
66 deduce TYPE_VPTR_FIELDNO from inheritance info and fieldname info.
67 * coffread.c (decode_base_type): Allocate TYPE_CPLUS_SPECIFIC for
69 (read_struct_type): Ditto.
70 * dwarfread.c (struct_type): Ditto.
72 * symtab.c (read_range_type): Don't set TYPE_MAIN_VARIANT.

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

123 Motorola 88000 port without tears, I mean without tdescs.
125 * m88k-tdep.c: Blow away all tdesc stuff.
126 Provide functions for all the frame-related macros in
127 tm-delta88.h. Adopt i960-style EXTRA_FRAME_INFO.
128 (examine_prologue, frame_find_saved_regs, skip_prologue): borrow
129 from i960-tdep.c and adapt to the function prologues on the 88k.
130 (read_next_frame_reg): Borrow from mips-tdep.c.
131 FIXME: frame_locals_address should go away.
133 * tm-delta88.h: Dump all the tdesc stuff.
134 Macros for all frame-related stuff call fns of same name.
135 Remove duplicated definitions. FP_REGNUM becomes same as
138 * xm-88k.h: Eliminate lots of library dependencies, now handled
139 in libiberty. Eliminate KDB nonsupport.
141 * doc/gdbint.texinfo: Add rudiments on frames. FIXME, add more.
144 * stack.c (frame_info): Mark frameless functions.
145 Print locals address (FIXME, remove if same).
146 * blockframe.c: Comment changes, FIXME after.
147 * coffread.c: Even without TDESC, need to zap "@" symbols.
148 Don't register for wierd format names; change the names in BFD.

158 Tue Nov 12 13:43:26 1991 Per Bothner (bothner at cygnus.com)
160 * symtab.c (decode_line_1): Remove spurious call to operator_chars.
162 Allow setting breakpoints on C++ destructors.
163 * valops.c (destructor_name_p): Don't check TYPE_HAS_DESTRUCTOR,
164 since it lies. Rely on callers to catch missing destructors.
165 * symtab.c (decode_line_1): For example (see above), here.
166 * buildsym.c, symtab.h: Remove TYPE_FLAGS_HAS{CON,DE}STRUCTOR
167 flags since they are no longer used.
169 Fixes to support C++ methods with functional parameters.
170 * c-exp.y (func_mod rule): Allow (and ignore) list of parameter
171 types in a function type.
172 * eval.c (parse_and_eval_type), value.h: New function,
173 parse_and_eval_type, is based on old code from check_stub_method.
174 But don't actually evaluate the cast, since that calls
175 value_cast(), whcih may fail. Just extract the type
176 from the parsed expression.
177 * values.c (check_stub_method): While looping through the
178 arguments, adjust depth *after* parameter has been handled.
179 Replace call and setup of parse_and_eval with new function
182 Tue Nov 12 09:40:07 1991 Fred Fish (fnf at cygnus.com)
184 * utils.c, rem-multi.shar: Remove fixed arg count version of
187 * altos-xdep.c, arm-xdep.c, coffread.c, command.c, convex-xdep.c,

189 m88k-xdep.c, main.c, printcmd.c, pyr-xdep.c, source.c,
190 sun386-xdep.c, symm-xdep.c, umax-xdep.c, values.c, xcoffread.c:
191 Change all instances of use of fixed args concat() to variable
192 args concat() now located in libiberty.
194 Tue Nov 12 07:23:46 1991 John Gilmore (gnu at cygnus.com)
196 * Makefile.in: Add xcoffread.c, xcoffexec.c.
197 * xcoffread.c: New file for handling AIX mangled-coff files.

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

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

247 * dbxread.c: Make more errors into complaints.
248 (push_subfile, pop_subfile): Move to buildsym.c.
249 (dbx_symfile_read, dbx_symfile_init, fill_symbuf, read_dbx_symtab,
250 start_psymtab, psymtab_to_symtab_1, read_ofile_symtab,
251 dbx_psymtab_to_symtab, ): Use bfd ops, don't use file descriptor.
252 Pass objfile. Change callers.
253 (fill_symbuf, SWAP_SYMBOL): Take bfd as arg.
254 (read_dbx_symtab): Just wipe out new symbols, not all, on error.
255 (end_psymtab): Blow away psymtab if empty.

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

281 * dwarfread.c (scan_compilation_units, start_psymtab,
282 process_dies, end_symtab, dwarf_build_psymtabs,
283 read_lexical_block_scope, read_func_scope, read_file_scope): Take
284 and use objfile argument.
285 (psymtab_to_symtab_1, read_ofile_symtab): Don't take or use file
286 descriptor. Use BFD internal functions instead.
287 (end_symtab): Call global allocate_symtab.
289 * elfread.c, target.c: Minor changes to accommodate objfiles.
290 * symtab.h: partial_symbol_table has no symfile_name member now.

292 (struct symtab): Add objfile * and objfile_chain * of symtabs.
293 (struct partial_symtab): Add objfile * and objfile_chain * of
294 psymtabs. Remove symfile_name.

307 * command.c: Include param.h.
308 * defs.h (warning_setup, warning): Declare.
309 * expprint.c (print_subexp, UNOP_MEMVAL case): Lint.
310 * inflow.c (new_tty): Use USE_O_NOCTTY #define.

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

986 Wed Sep 18 15:55:51 1991 John Gilmore (gnu at cygnus.com)
988 Merge multiple-language support, and partial Modula-2 support,
989 from Andrew Beers <beers@cs.buffalo.edu>.

1085 Tue Sep 17 08:37:41 1991 John Gilmore (gnu at cygint.cygnus.com)
1087 Add Andrew Beers' changes for Modula-2 support. His ChangeLog
1088 entries are enclosed herein. Not all of these changes
1089 have been merged into the master GDB sources -- check the
1090 ChangeLog above here for the merge log.
1092 Mon Jun 3 17:05:45 EDT 1991
1094 m2-exp.y Created. Tested outside of GDB for a few days. Proper
1095 operators were added, C specific operators and tokens
1096 removed. yylex() revamped to some extent. Still things
1097 missing from the grammar, such as sets.
1098 Tested for two weeks in GDB v3.5.
1100 Tue Jun 11 17:23:48 EDT 1991
1102 m2-exp.y Added boolean constants TRUE and FALSE to the grammar
1103 so they are built-in. Sort of a hack.
1105 Fri Jun 14 12:53:51 EDT 1991
1107 m2-exp.y Added range checking for numeric constants. Any numeric
1108 constant is assumed to be of builtin type INTEGER unless:
1109 (1) it is octal or hexadecimal, in which case it is a
1110 CARDINAL; (2) it is too big to fit into an INTEGER, in
1111 which case it is a CARDINAL.
1112 eval.c Added simple range checking for +, -, and * on integers.
1113 Doesn't work very well for *, since 6 * 1,000,000,000 =
1114 1,705,032,704, which fails the simple test of result >=
1115 first_operand, no matter in what order the operands are.
1117 Tue Jun 18 14:11:30 EDT 1991
1119 Broke the parser into parts, one containing the C grammar and the other
1120 containing code to be shared by all of the grammars.
1122 The following files no longer exist:
1127 The following files were added:
1129 c-exp.y (The C grammar)
1130 m2-exp.y (The Modula-2 grammar)
1131 parser-code.c (Code that is shared by the above grammar)
1135 Makefile.dist Changed to reflect the above dependencies. NOTE: It is
1136 now necessary to use the Bison compiler compiler, since it
1137 will generate function/variable prefixes other than yy.
1139 Tue Jun 18 16:47:49 EDT 1991
1141 symtab.[ch] Added the external variable working_lang, than holds the
1142 value of the current working language.
1143 Added the ennumerated type language_mode, with the values
1144 language_auto and language_manual, the former meaning that
1145 GDB sets working_lang as needed, and the latter meaning
1146 that the value of working_lang is totally under user
1148 symtab.[ch] Added the Modula-2 pervasive types INTEGER, CARDINAL,
1149 REAL, BOOLEAN and CHAR. Also added the type codes
1150 TYPE_CODE_BOOL and TYPE_CODE_CHAR.
1151 utils.c Added set_language_command and show_language_command to
1152 implement the GDB support commands "set language" and
1154 expression.h A number of identifiers were added to the type exp_opcode
1155 to facilitate Modula-2 builtin functions, integer
1156 division, and array indexing.
1158 Wed Jun 19 13:25:58 EDT 1991
1160 language.h Added the macro STRICT_TYPE, which evaluates to non-zero
1161 if the language specified by working_lang requires the use
1162 of strict typing of expressions. Eventually, even this
1163 will be able to be changed by the user.
1164 Added the macro RANGE_CHECK, which evaluates to non-zero
1165 if the language specified by working_lang requires the
1166 checking of a value against the domain of its type.
1167 Eventually, even this will be able to be changed by the
1169 language.[ch] Predicates involving types (simple_type, ordered_type,
1170 same_type, integral_type, numeric_type, character_type,
1171 boolean_type, float_type) are added. These predicates are
1172 based on the current value of working_lang, and are handy
1175 Wed Jun 19 15:39:34 EDT 1991
1177 eval.c Added the function type_array_rank which computes the rank
1179 valarith.c Added the funtion value_bool, which when given a integer
1180 value.h value (ie. struct value *) as an argument, it returns a
1181 boolean value (ie. struct value *) true if that integer
1182 is non-zero, and a boolean value false otherwise.
1183 valprint.c Added cases for TYPE_CODE_BOOL, so Modula-2 BOOLEAN values
1184 will print out properly.
1186 Wed Jun 19 16:36:34 EDT 1991
1188 valops.c Added the function value_capitalize, which returns it
1189 value.h argument capitalized if its argument is a lowercase
1190 letter, or the argument unchanged if its argument is not a
1192 valarith.c Added the function range_check_p, which returns non-zero
1193 value.h if its value argument is between the integral bounds upper
1195 Added the function range_check_enum_p, which makes sure
1196 that its value argument is a valid member of the domain of
1198 Added the function range_check_range_p, which makes sure
1199 its value argument lies between the upper and lower bounds
1200 of its type argument, which must be a ranged type.
1201 Added the function check_array_index, which range and type
1202 checks an index of an array.
1203 Added the function value_multi_subscript, which computes
1204 array[idx1,idx2...idxN], given a value array and an array
1205 of values representing indicies.
1206 values.c Changed value_from_long to work with TYPE_CODE_CHAR and
1207 unpack_long to work with TYPE_CODE_BOOL and
1210 Wed Jun 19 18:04:08 EDT 1991
1212 symtab.c Stored pervasive types in a structure and make
1213 lookup_pervasive_type() a lookup function that was based
1214 on working_lang. If lookup_pervasive_type() returned
1215 non-zero, then that value was returned (a fix, since
1216 before it simply wouldn't return the pervasive type.)
1217 language.h Added the macro CAST_IS_CONVERSION, which evaluates to
1218 non-zero if the language specified by working_lang means
1219 "conversion" when it says "cast".
1220 valops.c Added the function value_real_cast(), which performs a
1221 value.h *cast*, not a *conversion*, which is what value_cast()
1222 does when it can. In particular,
1223 value_cast(<float_type>,4) = 4.0, while
1224 value_real_cast(<float_type>,4) = some mess.
1225 eval.c Modula-2 builtin functions implemented: ABS, CAP, CHR,
1226 parser-code.c FLOAT, HIGH, MAX, MIN, ODD, ORD, TRUNC, and VAL.
1227 expression.h Added macros MAX_OF_TYPE and MIN_OF_TYPE to work with MAX
1228 and MIN on integral types. *NOTE*: These are currently
1229 hardcoded to work only if there are 8 bits per storage
1231 eval.c Made logical functions call value_bool to return a
1232 properly typed boolean value, based on working_lang.
1234 Thu Jun 20 11:55:27 EDT 1991
1236 valprint.c Types now print out in a Modula-2 fashion. This works for
1237 the cases when the type is printed out step-by-step, that
1238 is, it doesn't work when the name of a structured type
1239 (which includes the keyword "struct", etc.) is simply
1241 FIXME: Perhaps this is bad. Parts of it seem to kludgey,
1242 since type specifications in C and Modula-2 are very
1243 different. The C printing of a type is very recursive,
1244 whereas in Modula-2 it is generally very simple. C has
1245 type prefixes and suffixes, which have no real analogue in
1246 Modula-2. Maybe type_print() should call a language
1247 specific type printer. This is also advantageous if we
1248 compile GDB to exclude some of the languages. We'll just
1249 leave those functions out.
1251 Thu Jun 20 16:57:10 EDT 1991
1253 dbxread.c When reading the complete symbol table in (via
1254 psymtab_to_symtab()), the number and types of function
1255 arguments are added to a function type. define_symbol()
1256 calls add_param_to_type() to accomplish this.
1257 Assumption: when we come across a function definition
1258 (N_FUN symbol with an 'f' or 'F' in the name), its
1259 arguments will appear before another function definition.
1260 When a function is found, a pointer to its type is placed
1261 in the global in_function_type. Changes that
1262 add_param_to_type() makes are to this global.
1263 valprint.c The type of a function now includes (for Modula-2) the
1264 types of its parameters.
1265 eval.c Type checking and a check for the proper number of
1266 arguments is now done for function calls. Not sure of the
1267 impact this has on C++ member function yet.
1269 Thu Jun 20 19:58:48 EDT 1991
1271 valprint.c Rewrote the type printer. Broke it into two language
1272 specific parts, adding the functions type_print_m2() and
1274 An unfortunate consequence is this: if you debugging a C
1275 program in Modula-2 mode (why?), info types does not work
1276 well with regular expressions, since the types are printed
1277 out in Modula-2 terminology, but stored in C terminology.
1278 language.[ch] Added the functions new_type_last(), type_keyword(), and
1279 type_sep() to aid in the printing of typedefs.
1280 symtab.c Made the printing of typedefs as language independent as
1281 possible through calls to new_type_last(), type_keyword(),
1284 Fri Jun 21 11:50:26 EDT 1991
1286 dbxread.c Check all incoming ennumerated types. If it looks like
1287 Modula-2's BOOLEAN type, then change the type_code of the
1288 type to TYPE_CODE_BOOL so we can process it as a boolean
1290 valprint.c Replaced some of the 0x%x with calls to sprintf and
1291 hexformat() in val_print().
1292 language.[ch] Added the function hex_to_string(), which converts its
1293 integral argument to a hexadecimal number (format is
1294 language based) and returns the result as a string.
1296 Mon Jun 24 12:25:07 EDT 1991
1298 valprint.c Some functions call type_print_1() directly, instead of
1299 value.h using type_print(), so they can specify where (column) to
1300 print things. Since type_print() takes care of language
1301 dependence, that needs to be called first. Added a
1302 parameter depth to type_print() (so it is now like
1303 type_print_1). Changed type_print to type_print_at, and
1304 made type_print a macro that passes a depth argument of
1306 symmisc.c Changed all calls to type_print_1 to calls to
1308 Makefile.dist Made it possible to build GDB for a specific set of
1309 depend languages. Do this by passing a definition for the macro
1310 LANGS to make. LANGS should be a string containing a
1311 space-separated list of language names (ie. LANGS="c m2").
1312 The default is to build all languages. Note that grammar
1313 files must follow the naming convention of <lang>-exp.y.
1314 gdb.lang This holds the current value of the LANGS macro. It is
1315 examined every time make is called, and is updated if
1317 eval.c Added #ifdef _LANG_<lang> to these files.
1318 expread.c Still need to add them to dbxread.c and coffread.c.
1326 Mon Jun 24 16:33:11 EDT 1991
1328 language.[ch] Added the functions hexformat_pre() and
1329 hex_to_string_pre(), which take a prefix argument to
1330 include in the format string. Thus, hexformat_pre("08") will
1331 return "0x08x" (if the working language is language_c).
1332 Made hexformat() and hex_to_string() calls to the above
1333 with "" as the prefix argument.
1335 am29k-pinsn.c, arm-pinsn.c, breakpoint.c, convex-tdep.c, exec.c, core.c,
1336 dbxread.c, i386-pinsn.c, i386-stub.c, i386-xdep.c, i960-pinsn.c,
1337 infcmd.c, inflow.c, m68k-pinsn.c, m68k-stub.c, m88k-pinsn.c,
1338 mips-pinsn.c, mips-tdep.c, ns32k-pinsn.c, printcmd.c, pyr-pinsn.c,
1339 pyr-tdep.c, pyr-xdep.c, remote-vx.c, remote.c, solib.c, source.c,
1340 stack.c, sun386-xdep.c, symfile.c, symm-xdep.c, symmisc.c, tahoe-pinsn.c,
1341 valprint.c, vax-pinsn.c
1343 Changed all occurences of 0x%[0-9]*l*x in printf format strings to
1344 calls to hexformat() and hex_to_string(). Format strings without
1345 the leading "0x" were ignored.
1347 depend Updated to take the above into account.
1350 Tue Jun 25 15:27:18 EDT 1991
1352 symtab.h Added the types range_mode_t, range_check_t, type_mode_t,
1353 and type_check_t to keep track of the current state of
1354 range and type checking.
1355 main.c Added the variables range_mode, range_check, type_mode,
1356 and type_check to record the current state of range and
1357 type checking. Added initialization code to main().
1358 language.h Changed the macros STRICT_TYPE and RANGE_CHECK to examine
1359 the above variables.
1362 Tue Jun 25 17:57:08 EDT 1991
1364 dbxread.c process_one_symbol() updates the variable (enum language)
1365 source_lang based on the extension of the filename
1366 contained in the N_SO sybmol that started this symtab.
1367 When end_symtab() is called, the value of source_lang is
1368 put into the language field.
1369 stack.c select_frame() sets working_lang (and possibly type_check
1370 and range_check) to the language field of the symtab
1371 associated with the frame that is selected if working_mode
1372 is language_auto. If working_mode is language_manual, a
1373 warning is printed and working_lang is not set.
1374 language.c Added the function set_type_range(), which sets the value of
1375 type_check and range_check (if their modes call for
1376 automatic setting) based on the current value of
1377 working_lang. A non-zero argument will cause the current
1378 settings to be output.
1381 Wed Jun 26 14:51:40 EDT 1991
1383 eval.c Added range checks on assignment.
1384 m2-exp.y Added the grammar for sets to the language. Currently,
1385 these do not do anything except print an error message.
1387 Wed Jun 26 17:01:04 EDT 1991
1389 m2-exp.y Added the ability for parse_number() to parse negative
1390 numbers. A global flag is set upon encountering a unary
1391 minus. This was done to make, for example, 1 parse as a
1392 CARDINAL, and not as an integer, per Wirth's examples in
1393 Programming in Modula-2 ed.4.
1394 valprint.c Added support for "set radix 2" by then setting
1395 output_format to 't'.
1396 eval.c Implemented range checking on subrange types. Added calls
1397 to range_check_range_p for BINOP_ASSIGN and BINOP_VAL.
1398 Implemented MIN and MAX for ennumerated types. The
1399 minimum value of an ennumerated type is defined by Wirth
1400 as the first identifier, and the maximum as the last.
1401 m2-exp.y Made octal numbers ending with "B" be characters and those
1402 ending with "C" be numbers, per Wirth's book. (p. 34)
1404 Thu Jun 27 14:11:52 EDT 1991
1406 stack.c select_frame() now only sets working_lang, it does not
1407 notify the user. If working_mode is language_manual, then
1408 a warning is issued once.
1409 main.c At the end of each call to execute_command(), working_lang
1410 is checked against the local static (enum language)
1411 current. If they differ and working_mode is
1412 language_auto, the new settings of language, type and
1413 range checking are printed out.
1414 stack.c Modified frame_info() to include the language of the
1415 current frame in the output of "info frame".
1416 language.[ch] Added the function language_str() which returns the name
1417 of the current language.
1419 Fri Jun 28 15:33:14 EDT 1991
1421 m2-exp.y Added the built-in procedures INC, INCL, DEC, and DECL to
1422 the language. INCL and DECL currently cause an error,
1423 since sets are not implemented yet. INC and DEC are
1424 implemented as PREINCREMENT/PREDECREMENT with one
1425 argument, and as ASSIGN_MODIFY with two arguments.
1426 eval.c Added type checking to the above cases.
1427 value.h Added not_lval_constant to the lval_type ennumerated type.
1428 not_lval_constant means that the value is a constant
1429 value; that is 3 or 'a' or TRUE, not as in a constant
1430 identifier. This is used to help coerce numbers such as 3
1431 to either signed or unsigned numbers.
1432 valops.c Added the function value_coerce_constants() which coerces
1433 constant integers as following: if one is a constant and
1434 the other is not, the constant's type is set to the type
1435 of the other argument. If both are constants and one is
1436 signed, the other is converted to a signed constant.
1438 Sat Jun 29 17:26:29 EDT 1991
1440 valarith.c Added a better range checker. It now checks range
1441 (successfully) on integral operations [+-] (signed and
1442 unsigned) for any C sized type. Still does not work well
1443 for multiplication.)
1444 int_in_size() returns an integer that is coerced to fit into
1445 specified number of bytes.
1447 Mon Jul 1 13:04:14 EDT 1991
1449 language.[ch] Added the function binop_result_type(), which returns the
1450 builtin (struct type *) type that would be the result of a
1451 binop on the two values V1 and V2.
1453 Wed Jul 3 19:22:53 EDT 1991
1455 source.c Extended source_info() to include the source language in
1456 the output from "info source".
1458 Fri Jul 5 13:48:52 EDT 1991
1460 utils.c Moved the support functions for the GDB set/show commands
1461 dealing with language into language.c.
1462 language.c Added the function language_info(), which displays info
1463 about the current working language, type and range check
1464 settings. Called via the GDB command "info language".
1465 Added an initialization routine _initialize_language(),
1466 that sets defaults for the language, type and range
1467 variables and sets up the new GDB commands.
1468 main.c Language setup moved to language.c.
1471 Mon Jul 8 10:10:22 EDT 1991
1473 valarith.c Debugged the range checker for arithmetic. Still does not
1474 work for multiplication very well.
1476 Mon Jul 8 12:40:37 EDT 1991
1478 language.[ch] Added the function value_true() which returns non-zero if
1479 its argument represents a boolean true value.
1480 breakpoint.c Changed breakpoint_cond_eval() to call value_true() to
1481 check the truth of an expression.
1483 Thu Jul 11 12:51:34 EDT 1991
1485 language.[ch] Added the predicate structured_type(), which returns
1486 non-zero if the argument is a structured type.
1487 Added the predicate pointer_type(), which returns non-zero
1488 if the argument is a pointer type.
1489 eval.c Added the ability to do addition and substraction on
1490 pointers and integers. This case simply bypasses the
1493 Thu Jul 11 14:41:42 EDT 1991
1496 Added the symbol N_DEFD (0x4a) which is a definition
1497 module dependency that is used by the GNU Modula-2
1498 compiler and the linker. It is not important to GDB,
1499 except that [dbx|coff|mips]read.c should ignore these
1502 Fri Jul 12 16:07:00 EDT 1991
1504 valprint.c Changed the TYPE_LENGTH(type) >= 0 to TYPE_LENGTH(type) >
1505 0 in val_print(). Also added statements to the else part
1506 to coerce type (argument to val_print) to a pointer type
1507 if it is an "array of unspecified length".
1508 valops.c Added the function value_m2_string(), which returns a
1509 (value) value which is a constant string, whose type is
1510 (ARRAY [0..n] OF CHAR). The length field of the type
1511 structure is set to zero, so it will be interpreted as an
1512 "array of unspecified length".
1513 stack.c Moved the language/frame mismatch check to
1514 main.c:execute_command().
1515 main.c The working language is recorded each time
1516 execute_command() is executed. If working lang has
1517 changed during its execution, then the new
1518 language/type/range info is printed out for the user. If
1519 the working language does not match the language of the
1520 frame, a warning is issued.
1522 Sat Jul 13 16:16:39 EDT 1991
1524 eval.c Moved all the type-checking stuff for operators to
1525 language.[ch] language.c. This is so we can keep language-specific
1526 stuff (like for what type operators are defined) in
1528 language.[ch] Added the function binop_type_check(), which checks to see
1529 if its two (value) arguments are type-compatible with its
1530 opcode argument. The opcode should represent an operation
1531 involving an operator. Also added the macro function
1532 unop_type_check, which calls binop_type_check with a
1533 NULL second argument.
1534 expprint.c Added Modula-2 operators to the op_print_tab, so info
1535 expression.h break works correctly. Also added "op_string", which
1536 returns the string corresponding to the (enum exp_opcode)
1537 opcode that is its argument.
1540 Sat Jul 13 18:26:18 EDT 1991
1542 coffread.c Added code to record the type of function arguments with
1543 each paricular function. Code is very similar to that
1545 dbxread.c Moved add_param_to_type() to symtab.c
1546 symtab.[ch] Added function add_param_to_type() from dbxread.c
1548 *** NOTE: The above additions have not been tested.
1550 Mon Jul 15 12:50:47 EDT 1991
1552 langauge.[ch] Added the functions type_error and range_error, which work
1553 like error() except if the type/range mode is set to
1554 *_mode_warn, then they do not do a return_to_top_level(),
1555 but merely print a warning.
1556 Also changed [set|show]_[type|range]_command() to support
1557 the new "warn" feature.
1559 Thu Jul 18 17:50:54 EDT 1991
1561 mipsread.c Added code to record the type of function arguments with
1562 each particular function. Code is very similar to that
1565 *** NOTE: The above additions have not been tested.
1567 Fri Jul 19 11:19:10 EDT 1991
1569 defs.h Added macros MAX_OF_SIZE, MIN_OF_SIZE, UMAX_OF_SIZE, and
1570 UMIN_OF_SIZE, which when given a size of a numeric type,
1571 return the maximum and minimum value it can hold. UMAX...
1572 and UMIN... return the result for unsigned types.
1573 symtab.h Added the macros MAX_OF_TYPE and MIN_OF_TYPE to operate on
1574 struct types. They call above macros.
1575 dbxread.c Renamed the MAX and MIN_OF_TYPE macros to ..._OF_CTYPE to
1576 avoid a name conlict with the above.
1577 c-exp.y Added range checking on numeric constants in
1578 parse_number() for completeness.
1579 valarith.c Made binop_user_defined_p() and unop_user_defined_p()
1580 return 0 if working_lang is not language_c.
1582 Thu Aug 8 14:17:22 EDT 1991
1586 breakpoint.c Documentation strings of some commands changed to
1587 eliminate the references to the C language where
1590 Tue Aug 13 15:48:03 EDT 1991
1592 m2-exp.y Added qualified identifiers to the grammar. The semantics
1593 are slightly different from those of the GDB operator ::
1595 m2-exp.y Added a rule to each grammar of the form: start ::= exp |
1596 type_exp, where type_exp is any valid type expression.
1598 eval.c Added the opcode OP_TYPE, and an error case in eval.c.
1599 printcmd.c Modified ptype_command() so it actually parses the input
1600 (necessary for type expressions with scope qualifiers).
1601 Added the function ptype_eval() which expects an
1602 expression composed of one OP_TYPE element.
1603 *.[ch] Replaced all occurences of parse_c_expression with
1605 *.[ch] Replaced all occurences of parse_c_1 with parse_exp_1
1607 [End of ChangeLog entries from Andrew Beers for Modula-2 support.]
1609 Mon Sep 16 17:19:46 1991 John Gilmore (gnu at cygnus.com)
1611 Small fixes from Peter Schauer:
1613 * infrun.c (child_attach): Lint.
1614 * solib.c (find_solib): Handle shared libs version 2.
1616 Small fixes from David Wood:
1618 * xm-ultra3.h (SYS_SIGLIST_MISSING): Typo.
1622 * remote-vx.c: Move <stdio.h> to top, for FILE. Fix from
1623 John S <basrai%kanga.dnet@c3po.sm-alc.af.mil>.
1625 * utils.c (wrap_here): Avoid wrap action of fputs_filtered if
1626 chars_per_line is at maximum (user typed `set width 0'). Fix
1627 from Andreas Schwab <schwab@ls5.informatik.uni-dortmund.de>.
1629 Tue Sep 17 17:31:04 1991 Stu Grossman (grossman at cygnus.com)
1631 * coredep.c: include ptrace.h where necessary.
1632 * mipsread.c(parse_lines): fix unsigned char problem that was
1633 messing up line numbers on SGI's and possibly other MIPS based
1635 * infrun.c (child_create_inferior): use better test to check
1636 return val from setpgrp().
1637 * tm-irix3.h, xm-irix3.h, tconfig/irix3, xconfig/irix3: add these
1638 for sgi/irix support.
1640 Wed Sep 18 04:33:31 1991 Per Bothner (bothner at cygnus.com)
1642 * mipsread.c (parse_symbol): Put non-static procedures
1643 in the global block.
1645 Fri Sep 13 00:14:52 1991 John Gilmore (gnu at cygnus.com)
1647 Patch together `text_start' and `text_end' for 29K port.
1649 * exec.c (exec_command): If NEED_TEXT_START_END, define the
1650 variables and set them based on the exec file.
1651 * am29k-tdep.c: declare text_start.
1652 * valops.c (call_function_by_hand): declare text_end.
1654 * inferior.h: Eliminate CANNOT_EXECUTE_STACK in favor of
1655 defining CALL_DUMMY_LOCATION as BEFORE_TEXT_END. This is
1656 because machines that do this will also have to know to
1657 set NEED_TEXT_START_END. Besides, it was a redundant way to
1659 * tm-29k.h, tm-convex.h, tm-np1.h: Eliminate
1660 CANNOT_EXECUTE_STACK, define CALL_DUMMY_LOCATION and
1661 NEED_TEXT_START_END.
1663 Thu Sep 12 00:22:24 1991 John Gilmore (gnu at cygint.cygnus.com)
1665 AMD 29000 changes from David Wood <wood@david.ultra.nyu.edu>:
1667 * Makefile.in (CLIBS): Put XM_CLIBS and TM_CLIBS at end.
1668 Pass MUNCH_DEFINE to munch whenever we run it.
1669 * am29k-pinsn.c (print_insn): Handle NOP specially. Avoid %#x
1670 format string; use 0x%x instead.
1671 * am29k-tdep.c: Use DUMMY_SAVE_GREGS and RETURN_REGNUM.
1672 * ultra-xdep.c, xm-ultra.h: New files for Ultracomputer host system.
1673 * xm-rtbsd.h: New host support for RT/PC running BSD Unix.
1674 * inflow.c: Handle `short' process group IDs.
1675 * infptrace.c (fetch_register): Support CANNOT_FETCH_REGISTER,
1676 and check for ptrace errors.
1677 * coffread.c (SDB_REG_TO_REGNUM): Define if not already.
1678 (coff_symfile_init): Initialize text_bfd_scnum.
1679 (read_coff_symtab): Use it to find the text [and absolute?] sections.
1680 * ../config.sub: Add vendor nyu and os "sym[1-9]*".
1681 * configure.in: Add hosts rtpc-*-* and a29k-*-*.
1682 Merge target arm case with other "easy" cases. Add target
1683 cases a29k-*-none (rehack of am29k), a29k-*-kern (remote to
1684 Ultracomputer kernel), and a29k-*-sym1 (ultracomputer OS's user
1686 * minimon.h, remote-adapt.c, remote-mm.c: Add.
1687 * munch: Cope with RT/PC putting fns in data segment.
1688 Restore ability to override `nm' by specifying MUNCH_NM.
1689 * xconfig/rtbsd, xconfig/ultra3: New host systems.
1690 * tconfig/a29k: Rename from tconfig/am29k. Add remote-mm
1691 and remote-adapt. Remove encapsulated coff #define's (the
1692 support should go in BFD, and gdb shouldn't know or care).
1693 * tconfig/a29k-kern: Same, but for remote kernel debugging.
1694 * tconfig/ultra3: For debugging user processes on Ultra3/Sym1.
1695 * tm-29k.h: Update BADMAG (though it should go away).
1696 Allow the register definitions to be overridden in another
1697 tm-file. Fix SR_REGNUM. Add a mess of _REGNUM's. Separate
1698 RETURN_REGNUM from GR96_REGNUM and DUMMY_SAVE_GREGS from
1699 DUMMY_SAVE_GR96, for handling kernel calling conventions
1700 that use GR64+ rather than GR96+.
1701 * tm-ultra3.h: New file, for use on Ultra3 Unix as well as for
1702 remote debugging of Ultra3 kernel. Includes tm-29k.h and
1703 overrides various things.
1705 * remote-mm.c (mm_attach, mm_wait): Handle attach like
1706 child_attach does, making a clean stop in the newly attached
1708 * remote-eb.c: Lint.
1710 * coffread.c: Make coffread independent of any particular
1711 variant of COFF. Avoid #include-ing any particular one except
1712 internalcoff.h. BFD now passes key values for symbol reading
1713 as part of its coff_data structure (LINESZ, SYMESZ, AUXESZ,
1714 and the symbol masks and shifts); use them.
1715 Remove obsolete end_of_text_addr.
1717 * exec.c: Remove unused include files.
1719 Wed Sep 11 19:38:44 1991 John Gilmore (gnu at cygint.cygnus.com)
1721 * Makefile.in (documentation targets): Pass $(M4).
1722 Bugfix from eggert@twinsun.com (Paul Eggert).
1724 * stack.c (down_silently_command): Check for stack existence.
1726 Tue Sep 10 23:08:29 1991 John Gilmore (gnu at cygint.cygnus.com)
1728 * Makefile.in (VERSION): Update to 4.0.3.
1730 Tue Sep 10 09:19:29 1991 John Gilmore (gnu at cygint.cygnus.com)
1732 * core.c (core_file_command): Print frame at coredump with
1733 its level number, by calling print_stack_frame.
1734 * frame.h: Add selected_frame_level, print_stack_frame.
1735 * frame.h, stack.c: Remove print_sel_frame, print_selected_frame.
1736 * convex-tdep.c, convex-xdep.c, infcmd.c, inflow.c, infrun.c:
1737 Change print_sel_frame and print_selected_frame callers to
1740 * dbxread.c (read_ofile_symtab): Avoid empty else clause.
1741 * symfile.c (free_named_symtabs): Ditto.
1742 * main.c (main): wrap_here needs an arg.
1743 * solib.c (find_solib): Avoid memory access if _DYNAMIC is zero.
1744 (solib_add): Avoid noise.
1745 (solib_create_inferior_hook): Lint.
1746 (sharedlibrary_command): Move dont_repeat to here.
1747 * utils.c (error): Call wrap_here to force buffered output.
1749 Small patches from Peter Schauer:
1751 * coffread.c (start_symtab): Free any existing line_vector before
1753 (read_coff_symtab): Ditto for type_vector.
1755 * source.c (lines_to_list): New variable, replacing function.
1756 (all uses): Use as variable.
1757 (_initialize_source): Add 'set listsize' and 'show listsize'.
1758 * utils.c (lines_to_list): Remove function.
1759 * stack.c (print_frame_info): Use as variable.
1760 * defs.h (lines_to_list): Remove declaration.
1762 Mon Sep 9 13:45:57 1991 John Gilmore (gnu at cygint.cygnus.com)
1764 * breakpoint.c (insert_breakpoints): Restore warning about
1765 the program might be running in another process, but only for
1766 systems with this brain death (#ifdef ONE_PROCESS_WRITETEXT).
1767 * xm-hp300bsd.h, xm-mips.h, xm-vax.h: Define it.
1769 * utils.c (error): if error_pre_print is set, print the string
1771 * main.c (main, print_gnu_advertisement, print_gdb_version):
1772 Reformat legalese so it always prints, but acts as an "I'm here"
1773 message while symbols are being read. If any errors occur,
1774 print a few newlines to set off the message and start it at the
1775 left margin. Remove mention of "help" command, and don't yak
1776 about symbol reading.
1777 (catch_errors): Error string is now printed first in case of
1779 * command.c (undef_cmd_error, lookup_cmd): On undefined command,
1780 suggest the "help" command.
1782 * Makefile.in (VERSION): Set to 4.0.2.
1784 Thu Sep 5 23:49:48 1991 John Gilmore (gnu at cygint.cygnus.com)
1786 * .gdbinit: Remove useless "rr" command. Set complaints
1787 to 1 for people debugging gdb.
1789 * breakpoint.c, remote-vx.c: Reword strings printed by
1790 catch_errors callers.
1792 Wed Sep 4 11:07:50 1991 John Gilmore (gnu at cygint.cygnus.com)
1794 * WHATS.NEW: "history write -> history save". Doc "write on/off".
1795 (Fix from kenc@viewlogic.com.)
1797 Fix some infrastructure to be able to cope with host and target
1798 machines with different sized basic types (ints, ptrs, etc).
1799 (Idea from pierre@la.tce.com (Pierre Willard).)
1801 * values.c (value_from_longest): Rename from value_from_long.
1802 Handle pointer types as well as integers, so that targets with
1803 different pointer sizes from the host can be accomodated.
1804 * breakpoint.c, convex-tdep.c, eval.c, expprint.c, printcmd.c,
1805 valarith.c, valops.c, valprint.c, value.h, values.c: Rename
1806 uses of value_from_long to value_from_longest.
1807 * eval.c, findvar.c, printcmd.c, valarith.c, valops.c: Pass
1808 the correct pointer type to value_from_long{est}.
1810 * doc/gdb.texinfo ($_, $__): Describe types of these variables.
1812 * remote-vx.c: Remove obsolete code for calling functions via
1813 vxworks kludge interface (it referenced value_from_long).
1815 * valops.c (value_string): Find malloc with lookup_misc_func, not
1818 Tue Sep 3 18:37:46 1991 John Gilmore (gnu at cygint.cygnus.com)
1820 Make writing to files work properly. (Fixes to BFD are also needed.)
1822 * core.c (core_open): Open file ourselves, read or r/w, depending on
1823 write_files. Use bfd_fdopenr.
1824 * gdbcore.h (write_files): New variable.
1825 * exec.c (write_files): Define variable, add set&show for it.
1826 (exec_file_command): Use write_files to open for read or r/write.
1828 Make shared library reading happen automatically. These changes
1829 are mostly from Peter Schauer <pes@regent.e-technik.tu-muenchen.de>.
1831 * inferior.h (stop_soon_quietly): Add to exported variables.
1832 * infrun.c (child_create_inferior): call solib hook, if defined.
1833 (child_attach): call solib hook, if defined.
1834 * solib.c: Include inferior.h. Add from_tty to so_list as kludge.
1835 (find_solib): Use lookup_misc_func rather than hand-rolled.
1836 (symbol_add_stub): New stub for catch_errors.
1837 (solib_add): Avoid output if !from_tty. Catch errors rather
1838 than just calling symbol_file_add and bombing.
1839 (solib_create_inferior_hook): Interface with the target process
1840 to let it read and alloc shared libs, then figure out what it did.
1842 * core.c (validate_files): Fix typo, soften warning.
1843 (Fix from Hiroto Kagotani <kagotani@cs.titech.ac.jp>.)
1845 * utils.c (fputs_demangled): Avoid duplicate printing if
1846 demangling is off. (Fix from J.T. Conklin <jtc@cayenne.com>.)
1848 * infrun.c (proceed): Cast -1 to (CORE_ADDR) before comparing.
1849 (Fix from pierre@la.tce.com (Pierre Willard).)
1851 * main.c (catch_errors): Change argument to a char * from an int,
1852 since a char * can point to a struct full of glop, but an int
1853 is not guaranteed to be able to hold a pointer.
1854 * breakpoint.c (breakpoint_cond_eval, bpstat_stop_status,
1855 breakpoint_re_set_one, breakpoint_re_set): Adapt.
1856 * core.c (core_open, solib_add_stub): Adapt.
1857 * remote-vx.c (symbol_stub, add_symbol_stub, callers): Adapt.
1859 Wed Aug 28 18:18:05 1991 John Gilmore (gnu at cygint.cygnus.com)
1861 * Makefile.in: Update VERSION to 4.0.1. Evade GNU Make bug
1862 by adding .NOEXPORT target.
1864 Fri Aug 23 17:14:25 1991 John Gilmore (gnu at cygint.cygnus.com)
1868 * Makefile.in (VERSION): Roll to 4.0.
1869 (gdb.tar.Z): Make refcard.ps as well, for shipment.
1871 Fri Aug 23 14:07:09 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1873 * doc/gdb.texinfo: minor rewordings, crossref to ptype from print,
1876 * doc/Makefile, Makefile.in: generate "gdb-all.texi" rather than
1879 * doc/rdl-apps.texi: renamed from rdl-apps.texinfo
1881 * Makefile.in, doc/Makefile, doc/.Sanitize, doc/gdb.texinfo:
1882 reflect above name change
1884 * WHATS.NEW: correct pointer to refcard.
1886 * doc/gdb.texinfo: update New Features, Installing
1888 * doc/gdbint.texinfo: add short description of configure +template
1890 Fri Aug 23 11:46:08 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1892 * doc/gdb.texinfo: update, fix bugs in "Installing" appendix
1894 Fri Aug 23 01:02:00 1991 John Gilmore (gnu at cygint.cygnus.com)
1896 * Makefile.in: Add config.sub, make doc/rdl-apps.texinfo for
1897 tar file, add dependencies for referenced doc files.
1899 Thu Aug 22 22:17:06 1991 Stu Grossman (grossman at cygint.cygnus.com)
1901 * coffread.c, symfile.c, stack.c: saberized.
1903 Thu Aug 22 16:20:27 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1905 * doc/refcard.tex: permuted Essential Commands sec
1907 * doc/gdb.texinfo: new C++ chapter; revised installation appendix;
1909 set/show symbol-reloading
1910 default set complaints 0
1912 RET-repeat disabled after prompted long displays
1913 processID (attach) interpretation of 2nd GDB cmdline arg
1915 Thu Aug 22 14:05:47 1991 Stu Grossman (grossman at cygint.cygnus.com)
1917 * expread.y, coffread.c, dbxread.c, target.c, mem-break.c,
1918 cplus-dem.c, values.c, valprint.c, symfile.c, remote.c,
1919 breakpoint.c, main.c: lint.
1921 Thu Aug 22 02:02:26 1991 John Gilmore (gnu at cygint.cygnus.com)
1923 Install new configuration scheme for GDB and friends.
1925 * config.sub: Translate ordinary names to three-part names.
1926 * configure: Use three-part names internally.
1927 * configure.in: Translate three-part names to filenames.
1929 * README, WHATS.NEW: Update for gdb-4.0.
1930 * Makefile.in: Roll VERSION to 3.99.
1932 Wed Aug 21 18:21:09 1991 John Gilmore (gnu at cygint.cygnus.com)
1934 * infptrace.c (KERNEL_U_ADDR_BSD): Include a.out.gnu.h.
1935 * i960-tdep.c, m68k-tdep.c, sparc-tdep.c, tm-i960.h,
1936 tm-m68k.h, remote-nindy.c: Change ext_format_XXX structs
1937 to single structures rather than arrays; when passing
1938 their address, use &. This avoids trouble with bdead compilers.
1939 * mcheck.c: Don't include <stdlib.h>; just declare "void abort();"
1940 instead. This avoids portability headaches.
1941 * mips-tdep.c (mips_do_registers_info): Only print FP regs if
1943 * source.c (open_source_file): Avoid ANSI const bdeath by
1944 skipping declaration and then casting result value.
1945 * tm-hp300bsd.h: Clarify comment.
1946 * utils.c (strstr): Result is const char *; ANSI bdeath.
1947 * xm-hp300bsd.h: Define HOST_BYTE_ORDER. Redefine INT_MIN,
1948 since system include file defines it differently from "defs.h",
1949 though the two are equivalent for our purposes.
1950 * tconfig/hp300bsd: Add m68k-tdep.o.
1952 Tue Aug 20 16:01:11 1991 John Gilmore (gnu at cygint.cygnus.com)
1954 * tconfig/sun*4: Remove warnings about system assembler.
1956 Mon Aug 19 13:44:46 1991 John Gilmore (gnu at cygint.cygnus.com)
1958 * mcheck.c: Avoid warning about undeclared abort fn.
1959 * tm-sparc.h (PC_ADJUST): Avoid calling error() from this;
1960 it causes recursive calls to error() when used in cleanups.
1961 To do so requires that we make it a function, so we do.
1962 * sparc-tdep.c (sparc_pc_adjust): New implem of PC_ADJUST.
1963 * utils.c (do_cleanups): Remove the current cleanup from the
1964 chain *before* calling it, in case error() is called from it.
1965 The result won't be pretty, but won't be an infinite loop either.
1967 Mon Aug 19 00:41:04 1991 Michael Tiemann (tiemann at cygint.cygnus.com)
1969 * dbxread.c (read_struct_type): Grok anon structs for C++.
1970 (vb_name, vptr_name): Null terminate these strings.
1972 Fri Aug 16 08:31:03 1991 John Gilmore (gnu at cygint.cygnus.com)
1974 Minor bug fixes from BSD Net2 gdb:
1976 * blockframe.c (get_prev_frame_info): If FRAME_CHAIN_COMBINE
1977 returns 0, there is no previous frame.
1978 * breakpoint.c (commands_command): If !from_tty, don't call
1979 input_from_terminal_p().
1980 * dbxread.c (record_misc_function): Speed up slightly.
1981 (compare_psymbols): Ditto.
1982 * infcmd.c (do_registers_info): Take a second argument to
1983 determine whether to print float registers. "info registers"
1984 does not do so anymore. "info all-registers" does, now.
1985 * mips-tdep.c, pyr-tdep.c (xxx_do_registers_info): Take second
1987 * tm-mips.h, tm-pyr.h (DO_REGISTERS_INFO): Pass second arg.
1988 * inflow.c (initialize_inflow): Set tflags_ours correctly.
1992 * breakpoint.c (bpstat_do_actions): Use a cleanup to restore
1993 executing_breakpoint_commands if we are interrupted by error.
1994 * coffread.c (init_lineno): Avoid problem with zero-sized linetab
1995 versus malloc/free. From: john@labtam.labtam.oz.au (John Carey).
1996 * core.c (solib_add_stub, core_open): Call SOLIB_ADD inside a
1997 catch_errors() so we can setup the frame regardless of whether
1998 the shared libs work.
1999 * ieee-float.c (double_to_ieee_extended): Get exponent from
2000 right place in little-endian systems. From John Carey.
2002 Thu Aug 15 18:43:57 1991 John Gilmore (gnu at cygint.cygnus.com)
2004 * main.c: Remove unused terminating_signals and catch_termination().
2005 (long_options): Terminate with a zero element.
2006 [Bugfix from Atsuo Kawaguchi <atsuo@hark86.harl.hitachi.co.jp>.]
2007 (gdb_readline): Make call-compatible with readline.
2008 (init_signals): Improve comments re vfork vs. signal.
2010 * utils.c (prompt_for_continue): Use new gdb_readline().
2011 If we prompt for continuation, we don't let CR repeat the previous
2012 command, once we get back to a prompt. It's too easy to keep
2013 hitting CR, expecting "--more--" prompts, and have some long
2014 command start repeating on you.
2016 Tue Aug 13 16:17:56 1991 John Gilmore (gnu at cygint.cygnus.com)
2018 * blockframe.c (frameless_look_for_prologue): Speed up by
2019 calling SKIP_PROLOGUE_FRAMELESS_P if it's defined.
2020 * tm-sparc.h (SKIP_PROLOGUE, SKIP_PROLOGUE_FRAMELESS_P):
2021 Define two variants, one faster.
2022 * sparc-tdep.c (sparc_frame_chain): Use target_read_memory
2023 and return zero, rather than giving an error.
2024 (setup_arbitrary_frame): Initialize the PC in the new frame.
2025 (skip_prologue): Add a second arg saying whether we're just
2026 checking for a frameless function or not.
2028 * core.c (core_open, core_close, core_xfer_memory): Move
2029 section table pointers and bfd* into the target_ops.
2030 (core_open): Allow errors in shared lib reading, etc.
2031 (core_files_info): Describe shared library sections.
2033 * exec.c (exec_open, exec_close, exec_xfer_memory, xfer_memory,
2034 exec_files_info, set_section_command): Move section table
2035 pointers and bfd* into the target_ops.
2036 (add_to_section_table): Add BFD to section table.
2038 * target.c (target_xfer_memory, target_info): Pass target to
2039 xfer_memory and target_info functions.
2042 * gdbcore.h: Move struct section_table.
2043 * target.h: New home of struct section_table.
2045 * solib.c (solib_add): New argument is the target_ops whose
2046 section list is to be added to, if any. Reallocate the
2047 sections in that target to add any that come from shared libs.
2048 (throughout) so_sections renamed to sections.
2049 (solib_xfer_memory): Deleted.
2050 * tm-sunos.h (SOLIB_ADD): Add target argument.
2051 (SOLIB_XFER_MEMORY): Delete.
2053 * core.c, exec.c, inftarg.c, remote-eb.c, remote-nindy.c,
2054 remote-vx.c, remote.c, target.c, target.h: Remove add_syms vector
2055 from target_ops. It's the same on all targets. Add two section
2056 pointers to target_ops.
2058 * stack.c (find_relative_frame): Dump ancient algorithm for
2059 "down", just use handy "next" pointers.
2060 (frame_command): Don't error if there is no stack; let user
2063 * inflow.c (new_tty_prefork, new_tty): New prefork routine
2064 modifies static state in the parent process; new_tty itself
2065 runs in the child and modifies the child's file descriptors
2066 to match the saved static state.
2067 * infrun.c (child_create_inferior): Call new_tty_prefork,
2070 * infptrace.c (child_xfer_memory): Add ignored target arg.
2071 * remote-eb.c (eb_xfer_inferior_memory): ''
2072 * remote-nindy.c (nindy_xfer_inferior_memory): ''
2073 * remote-vx.c (vx_xfer_memory): ''
2074 * remote.c (remote_xfer_memory): ''. Rename from
2075 remote_xfer_inferior_memory.
2077 * main.c (main): Only try to attach "corefile" argument if
2078 it starts with a digit.
2080 * symfile.c (symbol_reloading): New "set/show" variable.
2081 (symbol_file_add): Shorten message about symbol reading.
2082 (add_symbol_file_command): Merge with add_syms_addr_command,
2083 since this should work on all targets now.
2084 (stop_whining): Default to zero, to shut up complaints
2085 about bad symbol tables on many systems.
2086 (free_named_symtabs): Just exit unless symbol_reloading.
2088 * xm-sun3os4.h, xm-sun4os4.h: Define BROKEN_LARGE_ALLOCA,
2089 and add comment explaining shared library screw.
2091 * source.c: #if defined => #ifdef.
2093 Thu Aug 8 12:23:19 1991 John Gilmore (gnu at cygint.cygnus.com)
2095 * doc/gdbint.texinfo: Improve doc on porting to new OS's.
2097 Tue Aug 6 17:16:15 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
2099 * doc/rdl-apps.texinfo: provide default readline-appendix finder
2100 (doc/Makefile knows how to make one for local config)
2102 * Makefile.in: use doc/Makefile for doc targets
2104 * doc/Makefile: GDB documentation now has its own Makefile
2105 doc/refcard.tex: renamed from "gdbrc.tex"
2106 doc/.Sanitize: add Makefile; recognize renamed refcard.tex
2107 doc/gdbint.texinfo: add markup in "Cleanups" chapter
2110 Fri Aug 2 00:13:06 1991 John Gilmore (gnu at cygint.cygnus.com)
2112 * values.c (baseclass_addr): When reading target memory, use the
2113 length of the basetype, not the upper type. We've only malloc'd
2114 enough space for the basetype, leading to errors in free().
2116 * expprint.c (print_subexp): Print UNOP_MEMVAL of an OP_LONG that
2117 ends up as a function specially, since we know the actual type of
2118 the pointed-to address. This (somewhat) fixes display of
2119 expressions that include misc_function_vector names. Try `cond 1
2120 !strcmp("a","b")' then `i b'.
2122 * infrun.c: Move DO_DEFERRED_STORES from proceed() to resume().
2123 The child can be proceeded from inside wait_for_inferior in
2124 evaluating breakpoint conditions, and DO_DEFERRED_STORES was
2125 getting skipped in that case.
2127 * expprint.c (print_subexp): Use filtered output, since the
2128 subroutines we call use it, otherwise the output is horribly
2129 mangled, since output of wrappable stuff comes out late.
2131 * Makefile.in: Bump VERSION to 3.98.1
2133 * infrun.c (child_create_process): Use execlp to find the
2134 shell to exec our target program. This requires some fiddling
2135 with `environ' since there is no execlpe().
2137 Thu Aug 1 15:35:17 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
2139 * Makefile.in, doc/gdbrc.tex, doc/rc-* (new files):
2140 Minor rearrangement of refcard permits two new make targets--
2141 gdbrc.dvi DVI output for refcard, using CM fonts
2142 gdbrc.ps PostScript refcard, using PS fonts
2144 Wed Jul 31 16:46:21 1991 John Gilmore (gnu at cygint.cygnus.com)
2148 * TODO, Projects, WHATS.NEW, README: Update for gdb-3.98.
2149 * Makefile.in (gdb-all.texinfo): Avoid touching file if M4 dies.
2151 Wed Jul 31 16:35:58 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
2153 * doc/gdb.texinfo: last changes for release.
2154 Minor typo and formatting fixes; incorporated most fixes remaining from
2155 filed mail commenting on earlier drafts.
2157 Added warnings: pipes don't work in run command;
2158 conditions are converse of assertions;
2159 step over fn without debug info goes to next fn;
2160 vars may have "wrong" values near fn entrance, exit
2162 Added example from Kingston on printing repeated nonadjacent values
2164 Added explicit mention that in Emacs gdb mode C-c and C-z are like
2165 shell mode for signals
2167 Renamed "Stepping and Continuing" to "Continuing and Stepping" so it
2168 doesn't sound so much like its parent "Stopping and Continuing"; also
2169 moved entries on continue to top of section, so they don't get lost.
2171 Improved installation directions in appendix, added manual formatting
2174 Tue Jul 30 17:26:39 1991 John Gilmore (gnu at cygint.cygnus.com)
2176 * configure.in: Remove xm.h and tm.h even if we aren't linking
2177 new ones, so "./configure sun4; ./configure none" does the right
2178 thing. Assume that alldeps.mak and depend are already built in
2179 srcdir, and avoid running "make" (particularly "make depend",
2180 which involves "gcc") from inside configure. Build Makefile
2181 directly rather than building Makefile.conf first.
2182 * configure: Regenerate with above changes.
2183 * Makefile.in: Use $(BISON) to find bison. Roll VERSION
2184 to 3.98. Revise gdb.tar.Z procedure to produce a file
2185 called gdb-$(VERSION).tar.Z but which unpacks into a
2186 directory called "gdb". Move non-source files out of
2187 $(SFILES_SUBDIR). Pretty up alldeps.mak with comments.
2188 (depend): Don't try to do "gcc expread.y".
2189 (expread.o): Update dependencies by hand.
2191 Mon Jul 29 15:21:09 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
2194 Fixed a variety of small typos that prevented info from formatting
2195 cleanly; altered too-long heading for GPL Appendix, as discussed
2196 w/RMS; Changed date on cover to July 91.
2198 Fri Jul 26 13:20:02 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
2201 (1) Applied some fixes due to comments from Larry Breed (easier ones
2202 through chapsec 5.2)
2203 (2) Eliminated use of @footnote---had my doubts about it anyways, and
2204 it's broken in latest texinfo
2205 (3) Introduced *some* use of [] for optional arguments, where
2206 explanation is not simpler by listing cmd w arg and cmd w/out arg
2207 separately. Still not using @deffn.
2208 (4) Dropped in GPL-2. NOTE: one of GPL-2 or texinfo is broken; a
2209 couple of headings are too long. Need patches to texinfo or revision
2212 * Partial update to README (which still needs work for this
2213 release!): (1) use of configure corrected for new script,
2214 (2) "make gdb.dvi" and "make gdb.info" mentioned.
2216 Wed Jul 24 06:44:02 1991 John Gilmore (gnu at cygint.cygnus.com)
2218 * symtab.c (lookup_symbol): Don't complain right off about
2219 no debug symbols; use the misc function vector first.
2220 (list_symbols): Use misc function vector to find symbols
2221 that don't have debug info, and print them.
2222 (find_pc_symtab): Temporarily avoid fatal() when psymtab
2223 PC range doesn't match symtab PC range, as it does on the
2224 MIPS because our symtab reading isn't perfect.
2226 * dbxread.c (dbx_symfile_read): Make warning about
2227 "no debug symbols" slightly nicer.
2229 * source.c (select_source_symtab): If "main" symbol exists,
2230 but decode_line_spec can't find line info, don't just return
2231 a zero; try other source symtabs or give an error.
2233 * mipsread.c (parse_partial_symbols): Sort the psymtabs by
2234 their low addresses first, then rip through fixing high addrs.
2236 * ns32k-opcode.h (sfsr): Bugfix from Rune Nerg}rd,
2237 <runene@ifi.uio.no>.
2238 (NS32K_SVC_IMMED_OPERANDS): Reverse the #ifndef.
2240 Tue Jul 23 18:52:43 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
2242 * Minor, mostly mechanical, cleanup of doc subdir for clean
2243 makeinfo'ing and TeXing; also ensured gdb-all.texinfo (post-m4)
2244 and gdb.info (post- texinfo2 makeinfo) generated for distribution.
2246 Sun Jul 21 03:54:52 1991 John Gilmore (gnu at cygint.cygnus.com)
2248 Mostly MIPS and general symbol-reading fixups.
2250 * doc/gdbint.texinfo: Add documentation on symbol-reading
2253 * mipsread.c: Remove kludges around #include "ecoff.h".
2254 Remove redefinitions of a_magic, etc, no longer used.
2255 (parse_symbol, ): Convert "Internal:" printfs to complain()ts.
2256 Fix global overview comments to match symfile.c protocol.
2257 (mipscoff_new_init): Eliminate cur_hdr if we have one.
2258 (mipscoff_symfile_read): Eliminate unused code. Avoid
2259 sorting all the symtabs, when all we have read here is psymtabs.
2260 The symtabs are sorted as they are created anyway. Tell
2261 condense_misc_bunches whether we're mainline.
2262 (psymtab_to_symtab_1): Pass filename when recursing, to make
2263 stack trace more informative.
2264 (parse_partial_symbols): Assume cur_hdr as argument.
2265 (read_mips_symtab): Don't clobber cur_hdr, so it can be freed.
2266 Pass cur_hdr implicitly to parse_partial_symbols. Avoid checking
2267 the TYPE_NAME of char *, since that's done in symfile.c.
2268 (free_numargs, parse_symbol, add_symbol, add_block,
2269 shrink_linetable): Declare these fns void.
2270 (upgrade_type): Convert tree of if's to switch. Clean up
2271 bogus "off == 0" handling with a complaint. Avoid setting
2272 field bitpos and bitsize of array with lower and upper bounds.
2273 Check specified bitsize of elements against their actual type's
2274 bitsize, and complain if different. Complain about unknown
2276 (parse_fdr): Don't assume sizeof(char *) == sizeof (struct *).
2277 (psymtab_to_symtab_1): Print names of subsidiary files that
2278 are being read in. FIXME, we read far too many files. This code
2279 is not the problem, the problem is in parse_fdr where the psymtabs
2281 (cross_ref): Result should indicate that we used one aux entry
2282 normally, or two if we encountered a "next" entry. This used
2283 to leave the caller pointing at the wrong aux entry.
2284 (add_symbol): If overflowed cur_block, reallocate it larger,
2285 chase all pointers to it, and complain(), rather than clobber memory.
2286 (shrink_block): Use xrealloc rather than xmalloc-and-copy.
2287 (new_field): Only allocate one field initially, not two.
2288 Pull ++ out of macro argument. Simplify.
2289 (_initialize_mipsread): Avoid initialization of importd
2290 global_psymbols and static_psymbols.
2292 * symfile.c (psymtab_to_symtab): Depend on XXX_psymtab_to_symtab
2293 to properly set pst->symtab; avoid searching for it.
2294 (symfile_fns): Improve comments, add a FIXME.
2295 * dbxread.c: Update comments to reflect symfile protocol.
2296 (read_ofile_symtab, end_symtab): Return the symtab.
2297 (psymtab_to_symtab_1): Set pst->symtab.
2299 * coffread.c (coff_symfile_read): tell condense_misc_bunches
2300 whether we're mainline.
2302 * symfile.h (sym_fns): Remove unused sym_discard member.
2303 * coffread.c, mipsread.c, dbxread.c: Remove XXX_symfile_discard.
2305 * mtrace.c (mtrace): Take effect if mallwatch is set, even if
2306 the environment variable is not.
2307 * infcmd.c (finish_command): Use filtered printfs.
2308 * cplus-dem.c: Add struct tags to a few unnamed structs.
2309 * valops.c (value_coerce_array): Improve comments.
2310 * valprint.c (type_print_varspec_suffix): Print array size only
2311 if greater than zero.
2312 * m88k-tdep.c: Shift some lines left by one space, that had
2313 apparently been trashed at some point.
2314 * TODO: More things to do, a few got done.
2316 Thu Jul 18 22:46:05 1991 John Gilmore (gnu at cygint.cygnus.com)
2318 * symtab.h (LOC_EXTERNAL): Eliminate in favor of LOC_STATIC.
2319 (ldsymoff, ldsymlen, globals_offset, statics_offset): Improve
2321 * dbxread.c (read_dbx_symtab): LOC_EXTERNAL -> LOC_STATIC.
2322 * expread.y, findvar.c, symmisc.c: Ditto.
2323 * printcmd.c (address_info): Update printed forms of LOC_
2324 symbols. Elim LOC_EXTERNAL.
2325 (print_frame_args): Keep track of param stack offsets before
2326 re-looking up to find the local register param is kept in.
2328 * mipsread.c: Use <symconst.h> and <sym.h> rather than <syms.h>.
2329 Further integration of mipsread into gdb. Eliminate unused
2330 routines, duplicate declarations. Handle static symbols in
2331 psymtabs as well as external symbols. When reading symtabs,
2332 insert symbols into the correct block (global, static, or a local
2334 (read_mips_symtab, parse_partial_symbols): Don't pass useless
2336 (mipscoff_symfile_read): Don't call select_source_symtab.
2337 (parse_symbol): Use SYMBOL_VALUE_ADDRESS where appropriate,
2338 rather than SYMBOL_VALUE.
2339 (parse_external): Comment clobbering of top_stack.
2340 (parse_partial_symbols): Update comments. Allocate and parse
2341 static symbols as well as external symbols. FIXME, enum values
2342 are not handled in this pass, but should be. Inline new_psymbol.
2343 Use SYMBOL_VALUE_ADDRESS.
2344 (psymtab_to_symtab_1): Read symbols into global static block
2345 by default (until enter some function's local block context).
2346 (sort_blocks): Clean up STATIC_BLOCK as well as GLOBAL_BLOCK.
2347 (destroy_all_symtabs, new_psymbol): Eliminate, unused.
2349 * source.c (select_source_symtab): Select a source symtab
2350 from either the symtabs or, failing that, the psymtabs.
2351 (list_command): Update error message.
2352 (forward_search_command, reverse_search_command): Use getc, not
2353 fgetc, for speed. FIXME, add comment about buffers that die if
2354 overrun by long line.
2356 * values.c (unpack_field_as_long, modify_field): Avoid shifting
2357 by an entire word, which is not portable, if we have a 32-bit
2358 field. (Code in dbxread.c already turns such bitfields, if
2359 aligned, into ordinary ints, but fixing this will help for other
2360 symbol formats and for future changes.)
2361 * core.c (core_open): Handle ANSI const brain death.
2362 * utils.c (vprintf): Fix varargs typo.
2364 Sun Jul 14 00:42:53 1991 John Gilmore (gnu at cygint.cygnus.com)
2366 * findvar.c (find_var_value): Handle &function better.
2367 * TODO: Document work needed on &fn and &array.
2368 * printcmd.c (print_address_symbolic): New arg is the prefix
2369 to print if a name is printed.
2370 (print_address_demangle): Honor "set print address" now.
2371 Use new arg above to improve spacing of output.
2372 * valprint.c (val_print): When printing function pointers,
2373 print symbolic form too.
2374 * breakpoint.c (breakpoint_1): Use new print_address_symbolic.
2376 Mon Jul 8 19:02:46 1991 John Gilmore (gnu at cygint.cygnus.com)
2378 * core.c (memory_error): Reword error msg to mislead less.
2380 * mips-pinsn.c (print_insn_arg 'd'): Print $ with reg name.
2382 * mipsread.c (read_mips_symtab, read_the_mips_symtab,
2383 parse_partial_symbols): Use newer BFD internals (external_filehdr
2384 and external_aouthdr), byte-swap the fields that we care about
2385 before using them, and make the file header data local to
2386 read_the_mips_symtab rather than global.
2388 Sat Jul 6 01:34:15 1991 John Gilmore (gnu at cygint.cygnus.com)
2390 * ns32k-opcode.h (movmw, movmd): Fix opcodes. Bug fix
2391 from Rune Nerg}rd <runene@ifi.uio.no> on 5 Jul 1991.
2393 * main.c (command_line_input): Flush stdout and stderr
2394 before every call to readline. This reportedly fixes a bug
2395 that comes up in Sys V running emacs-gdb and/or xxgdb,
2396 when stdin/out are pipes or sockets.
2398 Thu Jul 4 14:47:06 1991 John Gilmore (gnu at cygint.cygnus.com)
2400 * configure.in, Makefile.in: Avoid rebuilding "depend" as much.
2401 Avoid declaring Makefile dependencies, because GNU Make stupidly
2402 tries to update it if we do.
2404 * coffread.c: Revise for minor changes to bfd internal coff
2407 * configure: If -template= is given a relative path, make it
2408 absolute before recurring in subdirectories.
2410 * configure, configure.in, Makefile.in: Install "configure" script
2411 as replacement for config.gdb.
2412 * config.gdb, Makefile.dist, Makefile.sdir: Remove
2413 * README: Update for configure, mostly. FIXME.
2415 * Add dec3100 as equivalent to littlemips. Indicate in all host &
2416 target config files that they are for the host. When the lines
2417 get copied into the Makefile, this makes it more obvious what's
2420 Mon Jun 24 23:49:07 1991 John Gilmore (gnu at cygint.cygnus.com)
2422 * sparc-opcode.h (trap opcodes): Avoid leading spaces or
2423 tabs, which end up in the disassembler output inadvertently.
2425 Wed May 29 23:01:03 1991 John Gilmore (gnu at cygint.cygnus.com)
2427 Make it compile cleanly in an ANSI GCC2 environment.
2429 * blockframe.c: <stdio.h>
2430 * cplus-dem.c: free takes a void *, ifdef __STDC__
2431 * dbxread.c (read_huge_number): avoid gcc2 bug hoisting calc of
2433 * defs.h (alloca): Avoid doing anything if alloca already def'd.
2434 * stddef.h, stdlib.h: Remove these files.
2435 * symtab.c: Avoid declaring qsort, close.
2436 * symfile.c: Avoid declaring close.
2437 * utils.c (vprintf): Declare "ap" arg as proper va_alist.
2438 * sparc-tdep.c: Avoid including lots of Sun-host-specific files.
2440 Assorted other changes.
2441 * dbxread.c: include "libaout.h", not "liba.out.h".
2442 * printcmd.c (print_frame_args): Set recurse properly for
2443 indentation of struct and array parameters.
2444 * valops.c (value_cast): Allow cast to void.
2445 * infrun.c (resume): If NO_SINGLE_STEP, call machine dependent
2446 single_step() in a target-independent fashion.
2447 * sparc-tdep.c (single_step): Don't call ptrace ourselves, just
2448 set up to be ready to continue. This makes us target independent.
2449 * infptrace.c (child_resume): Remove call to single_step; now
2450 can single step a SPARC target of any kind.
2452 Wed May 22 18:18:24 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
2454 * Makefile.dist, doc/gdb.texinfo, doc/*-m4.texinfo: split up GDB
2455 docn into separate sections---basically chapters, plus two loose
2456 pieces that can be configured to go in different places. This
2457 allows GNU m4 to preprocess the manual without coredumping.
2459 * Makefile.dist: tell TeX where to find texinfo.
2461 Mon May 20 12:15:04 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
2463 * Makefile.dist, doc/gdb.texinfo: respectively create, and use,
2464 the new target "rdl-apps.texinfo" which captures the Makefile
2465 variable that records where to find the Readline libraries.
2467 Sun May 19 05:36:59 1991 John Gilmore (gnu at cygint.cygnus.com)
2469 * tahoe-pinsn.c: #include "tahoe-opcode.h", not "opcode.h".

2471 * defs.h (const, volatile): Only define if not already defined.
2472 * Makefile.dist (gdb.tar.Z): Create doc subdir w/out CVS/RCS crud.
2474 * README: Update for release 3.95.
2475 * config.gdb: Don't create readline dir in subdir builds.
2476 * main.c: Include with "..." form for non-system include files,
2477 so "gcc -MM" for "make depend" works.
2478 Include readline files with "...h" rather than <readline/...h>.
2479 * mipsread.c: Include "ecoff.h" rather than "intel-coff.h".
2481 * coffread.c: Undo minor damage done by Rich Pixley. Use
2482 different internal and external representations of COFF
2483 data structures. Use new BFD routines for swapping them in and
2485 * symfile.c (free_named_symtabs): Avoid freeing file names that
2486 are null or empty. Old i960 tools seem to produce files that
2487 claim to have empty names, causing each successive file read
2488 to blow away the previous one.
2489 * sparc-xdep.c (deferred_stores): Repair minor damage by Rich.
2490 Move deferred_stores to top of file, but don't separate its
2491 #define's from its variable. Add commentary.
2492 * Makefile.dist: Fix Rich damage; undo "configure" changes in
2493 favor of keeping the (working) config.gdb. Move readline
2496 Fri May 17 12:49:56 1991 Per Bothner (via gnu at cygint.cygnus.com)
2498 * dbxread.c (read_struct_type): Try to handle g++ version 1 MI
2500 * infptrace.c (fetch_registers): no result, since now void.
2501 * tconfig/news: target depends on m68k-tdep too.
2503 Fri May 17 14:40:14 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
2505 * Makefile.dist: added readline/inc-*.texinfo to dependencies for
2508 * readline/inc-history.texinfo, readline/inc-readline.texinfo:
2509 applied various small fixes due to or inspired by RMS comments
2511 * doc/gdb.texinfo: finished using all RMS comments, save those for
2512 appendices on readline and cmd history (which are in other source
2515 Thu May 16 18:06:05 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
2517 * doc/gdb.texinfo: (1) Updated w/ref to RMS comments through
2518 chapter 9; (2) documented 'break' command's menu mode for
2519 overloaded names, in response to hgs problem report C++ p-31
2521 Wed May 15 11:02:48 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
2523 * doc/gdb.texinfo: (1) better introductory example; (2) more
2524 consistent use of @code, @samp, @file, @kbd throughout; small
2525 cleanups to first three nodes; (3) new "Contributors" node;
2526 (4) Appendix, Renamed Commands; (5) divert specialized startup
2527 instructions to "Targets" chapter for generic manuals, while
2528 leaving them up front for manuals specific to specialized
2529 environments; (6) apply fixes from RMS comments through chapter 4.
2531 * pretex.m4: modify explanatory text slightly (and redefine
2532 "regexp") to keep GNU m4 from complaining. (It still crashes
2533 later, but one step at a time...)
2535 Wed May 15 10:32:12 1991 John Gilmore (gnu at cygint.cygnus.com)
2537 * readline/readline.c (update_line): Avoid dereferencing a pointer
2538 before comparing it to its bounds. Saber caught this.
2539 (init_terminal_io): Don't set BC from the "pc=" termcap variable,
2540 and only set PC if tgetstr returned non-null. Saber caught this.
2542 Tue May 14 16:29:53 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)
2544 * Makefile.dist: put gdb.dvi stuff (updated to use M4 preprocessor
2545 stuff for config manual) here where it counts; updated
2546 to use new subdir structure (gdb/doc/).
2548 * Makefile: generated from above via
2552 * gdbint.texinfo: added instructions on generating gdb.info* files
2553 locally for release. These are ordinary info
2554 files, formatted from gdb.texinfo (via gdb-all.texinfo, see
2555 Makefile)---but due to use of texinfo 2, can't count on makeinfo
2556 to generate these, so we distribute them already formatted.
2558 * gdb.texinfo: included full Info node and menu crud (as generated
2559 by C-u M-x texinfo-master-menu using the texinfo-2 elisp code).
2561 * Makefile: updated "gdb.dvi" target to use M4 preprocessor;
2562 put in comments-for-future gdb.info target (one day makeinfo will
2565 Tue May 14 13:51:36 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)
2567 * gdb.texinfo: Updated to include new or old undocumented
2568 commands, at least the following (perhaps some others I forgot to
2569 record): info f, info float, info path, info program, info s, info
2570 set, info source, info terminal, info types, info user, set/show
2572 Also covered all recent GDB command renames for v4.
2574 Mon May 13 14:57:46 1991 John Gilmore (gnu at cygint.cygnus.com)
2576 * mipsread.c: Rather than keeping count of how many symtabs
2577 and psymtabs we have, for sorting purposes, count them when
2578 we need to sort. This fixes bug in rereading of symbol tables.
2580 Fri May 10 15:43:33 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)
2582 * infcmd.c: renamed "info path" to "show paths"

2597 symtab.h, target.c, target.h: Lint.
2598 * core.c: setup and select frame after reading shared libs,
2599 else reading shared libs will clobber them. Lint.
2600 * utils.c (error): Force out any buffered wrap text.
2602 Fri May 3 22:01:56 1991 John Gilmore (gnu at cygint.cygnus.com)
2604 * remote.c: Remove decls of memory_insert_breakpoint
2605 and memory_remove_breakpoint, no longer used. (Suggestion of
2608 * Makefile.dist: use ${subdir} in paths of BFD and LIBIBERTY,
2609 to make it easier to interface to "configure"'d libraries.
2611 Fri May 3 13:10:01 PDT 1991 Roland Pesch (pesch at fowanton.cygnus.com)
2613 * valprint.c: introduce "set p", "set pr", "show p" and "show pr" as
2614 aliases for set/show print.

3126 core.c, exec.c, remote-eb.c, remote-nindy.c, remote-vx.c,
3127 remote-vx.68.c, inftarg.c, remote.c: Add doc field to target struct.

3157 command is add-symbols.
3158 * target.c (dummy_target): Permit add_syms_addr_command.
3160 Sat Apr 13 14:46:07 1991 John Gilmore (gnu at cygint.cygnus.com)
3162 Permit symbols to be superseded when new symbol files have
3163 been read in, particularly for VxWorks.
3165 * dbxread.c (read_dbx_symtab): Allow N_SOL to cleanly take us back
3166 to the main file, as well as to include files. Also, put global
3167 functions into the global psymtab, to make "i fun" work.
3168 (end_psymtab): Free named symtabs and psymtabs for a file, once a
3169 new psymtab for it has been read.
3170 * coffread.c (end_psymtab): Free named symtabs and psymtabs for
3171 a file, once a new symtab has been read for it.
3172 * mipsread.c: FIXME. We need to do the same for MIPS, but it
3173 looks harder to determine the top-level block before it's been
3174 queued to the psymtab list.
3176 * symfile.c (symbol_file_add): Use filtered printing and wrap it.
3177 If we have wiped out any old symbol tables, clean up at end of
3179 (symbol_file_command): Don't reference symfile_fns if it's zero.
3181 * symtab.h (GLOBAL_BLOCK, STATIC_BLOCK, FIRST_LOCAL_BLOCK): New
3182 defines for the blocks of a blockvector that contain global and
3183 file-static symbols and the first of the smaller scope contours.
3184 * symtab.c (lookup_symbol, find_pc_symtab, find_pc_line,
3185 decode_line_1, make_symbol_completion_list): Use the above.
3186 * coffread.c (end_symtab, patch_opaque_types): Ditto.
3187 * dbxread.c (end_symtab): Ditto.
3188 * expread.y (block): Ditto.
3189 * mipsread.c (throughout): Ditto.
3190 * symmisc.c (free_named_symtabs): Ditto.
3192 * symtab.c (list_symbols): Process the first symbol of the
3193 static psymbols list.
3194 (types_info): Restore this function from its untimely #if 0.
3195 It's not perfect, but it is better than nothing.
3196 (_initialize_symtab): Restore "info types".
3198 Thu Apr 11 05:23:19 1991 John Gilmore (gnu at cygint.cygnus.com)
3200 * m68k-stub.c: Remote stub for 680x0's, created from
3201 rem-m68k.shar (which is removed).
3202 * nindy-share/{Makefile,Onindy.c,blout.h,env.h,nindy.c,ttyflush.c}:
3203 Remove RCS log stuff now that we use CVS and it blows our diffs.
3205 Wed Apr 10 14:18:06 1991 John Gilmore (gnu at cygint.cygnus.com)
3207 * symmisc.c (free_named_symtab): Make it work, in its current
3208 kludgy fashion. Change result to indicate if we blew away bkpts.
3209 * dbxread.c (end_symtab): Accumulate result from
3210 free_named_symtab and print warning if we blew user's state.
3211 * symfile.h: free_named_symtab now returns an int.
3213 Mon Apr 8 23:57:43 1991 John Gilmore (gnu at cygint.cygnus.com)
3215 * dbxread.c (dbx_symfile_read): Initialize psymbol list if this
3216 is the first symbol read, even if not mainline.
3217 (dbx_psymtab_to_symtab): symfile might be zero, cope.
3218 * exec.c (exec_ops): Add_syms_addr is valid in our tvec.
3219 (set_section_command): New command ("section xxx yyy" -- should
3220 be renamed to "set section xxx yyy" FIXME) which sets the
3221 base address of a section of the exec file, overriding the
3222 virtual address that BFD reports.
3224 Fri Apr 5 17:14:39 1991 John Gilmore (gnu at cygint.cygnus.com)
3226 * exec.c: Add add_syms_addr_command to exec_ops, so you can
3227 load symbols at any address while examining an exec file.
3229 Thu Apr 4 10:09:35 1991 John Gilmore (gnu at cygint.cygnus.com)
3231 * tm-i386v.h (FLOAT_INFO): Don't define it, since the code
3232 for printing the float info is host-dependent, not
3233 target-dependent. FIXME.
3234 * i386-pinsn.c: Move #includes to top, remove useless ones.
3235 * i386-tdep.c: Don't bother including <.../reg.h> since we
3236 don't use it (and it doesn't exist on host systems).
3238 * ieee-float.c (ieee_extended_to_double): Convert NaN to Inf.
3239 Convert negative numbers properly.
3240 (ieee_test): Make numbers really random; fix format arg.
3242 * infcmd.c (attach_command, detach_command): Don't repeat on CR.
3243 * core.c (core_detach): Unpush core_ops, which might not be on
3244 top. We used to just pop the top, which broke things. Don't
3245 need dont_repeat() any more.
3246 (core_file_command): Psst! Don't repeat it.
3247 * remote-nindy.c (nindy_detach): Don't need dont_repeat() now.
3248 * expprint.c (print_subexp): Avoid switch fallthru on
3249 BINOP_ASSIGN_MODIFY, so we can print += and such.
3250 * frame.h: Fix typo.
3251 * inflow.c (kill_command): After killing inferior, print our
3252 current frame in the core file, if we have one.
3253 (generic_mourn_inferior): When inferior dies, either select
3254 the current frame (in the new target, e.g. core file), or
3255 set both the current and selected frames to NULL.
3257 Changes from Peter Schauer.
3259 * infptrace.c: Avoid <sys/ptrace.h> on USG.
3261 * Make all file names fit in 14 characters (sigh and damn!):
3262 mv hp300hpux-xdep.c hp300ux-xdep.c
3263 mv symmetry-xdep.c symm-xdep.c
3264 mv symmetry-tdep.c symm-tdep.c
3265 mv convex-opcode.h convx-opcode.h
3266 mv tm-vxworks960.h tm-vx960.h
3267 mv tm-vxworks68.h tm-vx68.h
3268 mv Makefile.srcdir Makefile.sdir
3269 mv gdb-int.texinfo gdbint.texinfo
3270 mv remote-sa.m68k.shar rem-m68k.shar
3271 mv remote-multi.shar rem-multi.shar
3272 * Makefile.dist, README, config.gdb, convex-pinsn.c,
3273 tconfig/symmetry, tconfig/vxworks960, tconfig/vxworks68,
3274 xconfig/hp300hpux, xconfig/symmetry: Change names to shorter
3277 * command.c (user_info_1, user_info): New command for listing
3278 the user-defined commands.
3280 Wed Apr 3 15:00:26 1991 John Gilmore (gnu at cygint.cygnus.com)
3282 * dbxread.c (really_free_pendings): Clear file_symbols
3283 and global_symbols after freeing them; otherwise, running
3284 this function twice (if it appears twice on the cleanup
3285 chain), we try to free things twice.
3287 * dbxread.c (read_dbx_symtab): Calculate end_of_text_addr
3288 based on text_addr (the address of text in core), not on addr (the
3289 offset between text in the .o file and in core). This change
3290 is from Peter Schauer.
3292 * main.c: Define ALL_CLEANUPS as a cast of zero.
3293 (return_to_top_level): Use it.
3294 (main): Do all cleanups after each command run as part
3295 of the gdb startup sequence. Also do all cleanups before
3296 entering the command loop, and every time we exit the command
3297 loop and reenter. Before, the cleanups from the startup sequence
3298 were being left undone until the first error!
3299 (command_loop): Rename do_nothing cleanup to command_loop_marker
3300 so we can see it easily when examining the cleanup chain.
3301 (init_signals): Add another do_nothing for signal handling.
3302 (quit_command): Only try to kill target if it has execution.
3303 Problems in the target stack got us into a state where
3304 inferior_pid was nonzero but none of the targets had execution.
3305 In this state you couldn't exit gdb.
3307 * dbxread.c: Two changes from Peter Schauer.
3308 (echo_command): Fflush output after an echo command.
3309 (show_history): Pass all args to cmd_show_list.
3311 * utils.c (init_malloc): Call mtrace to turn on tracing
3312 if the environment variable MALLOC_TRACE is set to a file name.
3313 * mtrace.c: Add source file which provides a log of every malloc,
3314 free, and realloc to a trace file.
3315 * mtrace.awk: Add source file which analyzes the trace file.
3316 * Makefile.dist (GNU_MALLOC, MALLOCSRC): Add mtrace.{c,o,awk}.
3317 (VERSION): Roll to 3.94.3.
3319 * breakpoint.c (breakpoint_1): Add a space to "i watch" output.
3320 (check_duplicates): Don't bother with watchpoints.
3321 (set_raw_breakpoint): Comment about danger of this routine.
3322 (watch_command): Parse and eval all args before calling
3325 * solib.c (find_solib): Avoid error in referencing memory to
3326 see if any more shared libraries have been added. This is
3327 particularly useful if the target has terminated. Bug reported
3330 Changes from Peter Schauer <pesrem@regent.e-technik.tu-muenchen.de>
3331 in bringing up 3.94.2 on the Sun-3.
3333 * Makefile.dist: Include CFLAGS in rule for cplus-dem.o.
3334 * breakpoint.c (enable_breakpoint): Check for valid watchpoint
3335 expression (in scope) before reenabling watchpoint.
3336 * signame.c (init_sigs): Add missing declaration of i, fix
3337 sys_siglist declaration.
3338 * source.c (list_command): Fixed range computation to use
3340 * stack.c (backtrace_command): Do not allow command if target has
3341 no stack, print informative error message.
3342 * target.c (target_command): Do not write into command line
3343 because this fails if the target command is used in a user defined
3344 command. [This change was enhanced by gnu to support any-
3345 unique-prefix matching on target names.]
3346 * valops.c (value_struct_elt): Avoid infinite loop on an
3347 erroneous attempt to print the member of function (try p main.p).
3349 Mon Apr 1 17:05:45 1991 John Gilmore (gnu at cygint.cygnus.com)
3351 * expread.y (name_no_typename): Avoid reduce/reduce errors
3352 caused by ambiguity in handling NAME_OR_INT and NAME_OR_UINT.
3353 Since the GDB parser really doesn't use name_no_typename in a
3354 name-only context, the parser can't tell the diff between
3355 names and numbers here. Avoid allowing a name_no_typename
3356 to be a NAME_OR_*INT to resolve the conflict.
3358 Sun Mar 31 20:12:07 1991 John Gilmore (gnu at cygint.cygnus.com)
3360 Bugfixes from Mark Fox (markf@wrs.com) (test=testField.c):
3362 * valprint.c (val_print_fields): bitfield printing didn't handle
3363 byte order. Indirect through a few more fns to cope.
3365 * values.c (modify_field): also cope with byte order.

3369 Cleanup for release 3.94.2:
3371 * Makefile.dist: Pull REMOTE_OBS. Fix saber includes for BFD
3372 include files. Roll version to 3.94.2.
3374 * coffread.c (init_stringtab): Read length into unsigned char
3375 array before swapping; don't assume 32-bit longs.
3377 * target.c (target_info): Don't bother with get_sym_file, just use
3378 the symfile global variable.
3379 * symtab.h, symfile.c (get_sym_file): Delete it.
3381 * dbxread.c (dbx_symfile_init): Don't depend on long == 4 bytes.
3382 (define_symbol): Set symbol line number to 0 if not gcc-compiled.
3383 (read_type): Replace one more error() with complain().
3385 * mipsread.c (parse_partial_symbols): Replace printf with complain.
3387 * i960-tdep.c: Fix copyright attribution.
3389 * config.gdb: Quote all backquotes in doublequotes. You can
3390 quote me on that. BSD 4.4 shell found this one.
3392 * infptrace.c (throughout): The third argument to ptrace is an
3395 * infrun.c (wait_for_inferior): When program has terminated, we
3396 have to call target_terminal_ours before we pop that target off
3397 the stack (e.g. before a call to target_kill or
3398 target_mourn_inferior). This fixes problem where a program
3399 terminates, then GDB stops for (tty output) and you have to type
3400 "fg" to the shell to resume it. FIXME: This code for what to
3401 do after termination really should be in normal_stop instead.
3403 * gdbcore.h (read_memory_check): Change declaration; it changed
3406 * terminal.h: Include <sgtty.h> before <sys/ioctl.h>, since in BSD
3407 4.4 prereleases, this avoids a bug in their sgtty compatability
3409 * remote.c: Use terminal.h rather than hand-rolling the same.
3411 * signame.c, signame.h (psignal): Arg is unsigned, not int.
3412 * utils.c (strsave, strstr): Fix arg types.
3413 * valprint.c (val_print): lint
3415 MIPS symbol table support from Per Bothner:
3417 * symfile.c (symtab_fns): Remove initializer table that needs to
3418 be hacked for each new symbol file format supported.
3419 (add_symtab_fns): New function, chains symbol table
3420 handlers into the global list.
3421 (symfile_init): Search this list.
3422 * symfile.h: Add next pointer, declare add_symtab_fns.
3423 * coffread.c (_initialize_coffread): Call add_symtab_fns.
3424 * dbxread.c (_initialize_dbxread): Call add_symtab_fns.
3426 * mipsread.c (psymtab_to_symtab_1): return void instead of (struct
3427 symbol *). Thus, we no longer need the hack to trash
3428 pst->filename. Good, since that hack confused code in symfile.c!
3430 (reorder_symtabs, destroy_all_symtabs): Removed static
3431 all_symtabs, which was used to qsort symtabs in reorder_symtabs.
3432 Instead, the latter now uses a temporary array (stack-allocated
3433 from an obstack, and then freed).
3435 (parse_symbol): Added a hack to fix up BLOCK_{START,END} if they
3436 haven't been set in the outermost stBlock of a procedure. This was
3437 a problem with f77 binaries on Ultrix 4.?.
3439 (new_symtab, new_symbol, new_type): Continue changing code to use
3440 obstacks more and otherwise conform to dbxread internal style.
3441 Made the free_code of symtabs be free_linetable (as in dbxread)
3442 instead of free_contents. This implies memory leaks when reading
3443 a new symbol table, until the conversion is finished. Did change
3444 (struct symbol) and (struct type) to be allocated on the
3445 symbol_obstack. Blocks and blockvectors are among the things
3448 * mipsread.c (parse_partial_symbols, parse_fdr): It hasn't been
3449 tested much, but it solved one problem (reported by Meissner), and
3450 cleans up some other things. The problem happened when an
3451 included file contains actual code (functions) and not just
3452 definitions. The mips coff is a little inconvenient there, since
3453 it may cause a procedure to be mapped to the wrong psymtab.
3455 * mips-tdep.c (heuristic_proc_desc): Minor cleanup.
3456 * mips-xdep.c (fetch_core_registers): Minor cleanup. FIXME,
3457 this will need work for the new core paradigm.
3459 Opcode patches from the net:
3461 * mips-opcode.h: fix incorrect disassembly of the mfc1, cfc1, and
3462 ctc1 instructions. Also, the cvt.d.w and cvt.s.w instructions were
3463 missing altogether - they are added here. From Bruce Bauman.
3464 * mips-opcode.h: The low mask for C0 instructions was too small.
3465 From Garrett Lau. I modified the fix to check the entire 32-bit
3468 * ns32k-opcode.h: Fix opcodes for deiw and deid. From Bruce
3471 Thu Mar 21 12:56:46 1991 John Gilmore (gnu at cygint.cygnus.com)
3473 Roll in changes from Per Bothner (Tue, 25 Sep 90 11:11:04):
3475 * dbxread.c (read_type): Pointer subtraction (value_sub in
3476 valarith.c) sometimes failed because the types of the
3477 pointers being subtracted were not identical.
3478 These differed because dbxread.c was allocating pointer types
3479 using dbx_alloc_type+smash_to_pointer_type instead of
3480 lookup_pointer_type. I failed to find a justification for the
3481 former, so I changed it to use the latter. Similarly, I
3482 replaced smash_to_function_type by lookup_function_type,
3483 and smash_to_reference_type by lookup_reference_type.
3485 * mipsread.c (parse_symbol, upgrade_type, parse_procedure,
3486 _initialize_mipsread): corresponding changes.
3488 * symtab.c (smash_to_{pointer,reference,function}_type): eliminate.
3490 * source.c (mod_path): Do tilde_expand on each component of the path,
3491 rather than on the (list of) paths as a whole.
3492 (print_source_lines): Set first_line_listed in addition to
3493 current_source_symtab and current_source_line. If the source was
3494 not findable, after a "dir" command to fix the problem,
3495 a "list" would get the wrong lines.
3497 While I was there... (gnu):
3499 * dbxread.c (read_type): Change error to complaint.
3501 Thu Mar 21 12:56:46 1991 John Gilmore (gnu at cygint.cygnus.com)
3503 First attempt at detailed understanding of symbol table memory alloc.
3505 * dbxread.c (dbx_symfile_read): Free our string table if we
3506 aren't the mainline. Free the "info" struct since we're done with
3508 (init_psymbol_list): Free any previously allocated psymbol lists.
3509 (): FIXME: Should realloc-down the psymbol lists when done reading
3510 the main symbol file?
3512 * symmisc.c (free_symtab): Free fullname field too.
3514 * xm-hp300hpux.h (USG): #undef then #define so Makefile can -D.
3515 (REGISTER_ADDR): Make result type unsigned int.
3517 * xconfig/{i386*,hp300hpux,altosgas,altos}: All config files that
3518 define REGEX must also define REGEX1 (its dependency).
3520 Tue Mar 19 21:28:57 1991 John Gilmore (gnu at cygint.cygnus.com)
3522 * tconfig/i960: No longer works, points you at vxworks960 or
3525 * xgdb.c, XGDB-README: Remove file. Users can get the much
3527 * Makefile.dist: Remove all trace of xgdb.
3529 * breakpoint.c (breakpoint_1): Pass demangle arg to
3530 print_address_symbolic.
3531 (clear_breakpoints): Remove unused function.
3532 (breakpoint_re_set_one): Guts of breakpoint_re_set.
3533 (breakpoint_re_set): Use catch_errors to do them all anyway.
3535 * gdb-int.texinfo (Host versus Target): Add section on what is
3536 a "host" feature versus what is a "target" feature.
3538 * infcmd.c (path_command, path_info): Handle the PATH variable
3539 (object search path) as conveniently as the source search path.
3540 * environ.c (set_in_environ): Set some vars in GDB's environment,
3541 in addition to the child's. PATH, G960BASE, G960BIN for starters.
3542 * source.c (mod_path): New function, from guts of
3543 directory_command, modifies a path. Used by path_command.
3544 (directory_command): Call it.
3545 * defs.h (strsave): Declare.
3547 * utils.c (sevenbit_strings): Add new printing option.
3548 (printchar): Use it.
3549 (strsave): Provide this handy helper routine.
3550 (set_width_command): Rename set_screen_width_command.
3551 (_initialize_utils): "set screen-width" => "set width";
3552 "set screen-height" => "set height"; add sevenbit-strings.
3554 * infcmd.c (do_registers_info): Print floating point registers
3555 in raw hex as well as float format, regardless of whether it is
3556 a "virtual" convertible register.
3557 * tm-sparc.h (PRINT_REGISTER_HOOK): Print every pair of float
3558 regs as a double, just in case it's being used that way.
3559 * values.c (unpack_long): Comment on array/function coercion.
3560 (unpack_double): Argument is in target byte order now. For
3561 integer arguments, just call unpack_long and float the result.
3562 * m68k-tdep.c: include defs.h for "const" handling.
3563 * remote-nindy.c: Use ieee-float stuff.
3564 (nindy_fetch_registers): Unpack double regs to host double, then
3566 (nindy_store_registers): Pack extendeds to host double, flip
3567 around by misusing unpack_double, send as target double.
3569 * tm-vxworks68.h (FRAME_CHAIN): Handle current frame pointer of
3570 zero, as when stopped at the first instruction of a process.
3572 * blockframe.c: Fix filename in comment (param.h => tm.h).
3573 * sparc-tdep.c (skip_prologue): More explicit nudging comments.
3574 * tm-68k.h: Fix typos.
3576 Fri Mar 15 01:09:34 1991 John Gilmore (gnu at cygint.cygnus.com)
3578 Changes from a bringup on the DEC Vax under Ultrix 4.0.
3580 * coredep.c (fetch_core_registers): Pass end-address of register
3581 section to register_addr as expected. Don't call supply_register
3582 if we'd just pass it garbage.
3584 * dbxread.c (read_dbx_symtab): Skip N_NSYMS on Ultrix.
3586 * exec.c (xfer_memory): Use boolean xfer_fn result, not int.
3588 * target.c (push_target, target_info): Cast enums to int for < or
3591 * stack.c (print_frame_info): Identify source file & line
3592 even if we can't print it.
3594 * xm-vax.h (MISSING_VPRINTF): No longer missing in Ultrix V4.0.
3596 Sat Mar 9 10:08:20 1991 John Gilmore (gnu at cygint.cygnus.com)
3598 Clean up IEEE floating point support.
3600 * ieee-float.h: New file.
3601 * ieee-float.c: Write real routines to convert between host
3602 doubles and various target IEEE extendeds.
3603 * m68k-xdep.c: Eliminate assembler code for extended floats.
3604 * xconfig/{3b1,altos,altosgas,hp300bsd,isi,news,news1000,sun2os3,
3605 sun2os4,sun3,sun3os3,sun3os4}: Eliminate use of m68k-xdep.o.
3606 * tm-i960.h, tm-68k.h (REGISTER_CONVERT_TO_VIRTUAL,
3607 REGISTER_CONVERT_TO_RAW): Use ieee_extended_to_double and
3608 double_to_ieee_extended.
3609 * i960-tdep.c: Define ext_format_i960.
3610 * m68k-tdep.c: Define ext_format_68881.
3611 * sparc-tdep.c: Define ext_format_sparc, though unused.
3612 * Makefile.dist (HFILES): Add ieee-float.h.
3613 * inftarg.c: #include "ieee-float.h" for the REGISTER_CONVERT
3616 Obsolete the "coffstrip" program in favor of using BFD's strip.
3618 * nindy-share/coffstrip.c: Remove file.
3619 * nindy-share/nindy.c (coffstrip): Routine to run bfd_strip.
3620 * Makefile.dist: Remove references to nindy-share/coffstrip.c.
3621 * tconfig/nindy960: Remove reference to coffstrip.o.
3623 * Makefile.dist: Roll version number to 3.94.1 (not yet final).
3625 Wed Mar 6 09:56:45 1991 John Gilmore (gnu at cygint.cygnus.com)
3627 * symfile.h: Add symfile_bfd, common between dbxread and coffread.
3628 * dbxread.c: Remove static symfile_bfd.
3629 * infcmd.c (do_registers_info): Add PRINT_REGISTER_HOOK, though
3631 * inftarg.c (child_detach): Pop the child_ops vector if the
3632 detach is successful.
3633 * remote-nindy.c (nindy_create_inferior): Don't push a new
3634 nindy_ops since nindy uses the same one for execution and memory
3636 * core.c (core_ops): Use child_attach and child_create_inferior
3637 rather than default attach and create_inferior functions.
3639 Handle floating point registers in core files.
3641 * sparc-xdep.c (fetch_core_registers): Rewrite for float support.
3642 * sun3-xdep.c (fetch_core_registers): Rewrite for float support.
3643 This version untested since BFD doesn't yet support sun3 core
3645 * hp300hpux-xdep.c: Rewrite fetch_core_registers to new calling
3646 conventions. Fix comments and style. This version has not
3647 been compiled yet, since we have no HP inhouse.
3648 * core.c (get_core_registers): Look for two sections, ".reg"
3649 and ".reg2", and pass both to fetch_core_registers sequentially.
3651 Revise directory path yet again.
3653 * source.c (forget_cached_source_info): Not static any more.
3654 (init_source_path): New default source path is "$cdir:$cwd".
3655 (dir_command): Handle variable arguments ($cdir, $cwd).
3656 (source_info): Print "Compilation directory" rather than
3657 "Originally compiled in" to remind people of $cdir.
3658 (openp): If the path contains $cwd, use current directory.
3659 (open_source_file): If compilation directory is known, replace
3660 first $cdir in path with the compilation directory.
3661 (print_source_lines): Even if we can't print the lines, set the
3662 current symtab and line for future commands like "info source" or
3663 "breakpoint". Also, error message now contains the file name,
3664 line number, and file access error message.
3665 (_initialize_source): Fix help text to describe changes.
3666 * main.c (cd_command): Forget cached source info when we chdir.
3667 * utils.c (strstr): Add simple implementation.
3669 Tue Mar 5 01:41:40 1991 John Gilmore (gnu at fowanton.cygnus.com)
3671 * coffread.c (read_one_sym, init_linetable, init_stringtab):
3672 Byte-swap COFF symbol tables if necessary when reading them in.
3673 Use complain() to replace error message in one spot. Needs
3674 corresponding change in bfd/coff-code.h to make some symbol
3675 swapping routines non-static.
3677 Mon Mar 4 00:53:40 1991 John Gilmore (gnu at cygint.cygnus.com)
3679 Merge changes from Eirik Fuller, for UTek.
3681 * defs.h (errno): Add declaration.
3682 * altos-xdep.c, arm-xdep.c, convex-xdep.c, gould-xdep.c,
3683 hp300hpux-xdep.c, infrun.c, inflow.c, infptrace.c, i386-tdep.c,
3684 i386-xdep.c, pyr-xdep.c, mips-xdep.c, remote-eb.c, remote-nindy.c,
3685 remote-vx.c, source.c, standalone.c, stuff.c, sun386-xdep.c,
3686 symmetry-tdep.c, symmetry-xdep.c, umax-xdep.c, utils.c: Eliminate
3687 declarations of errno.
3689 * remote-eb.c: Define B19200 and B38400 as EXTA and EXTB.
3691 * remote-vx.c: Include <sys/time.h> for UTek; Sun gets it via
3692 <rpc/rpc.h> and <rpc/types.h>.
3694 Sat Mar 2 15:47:55 1991 John Gilmore (gnu at cygint.cygnus.com)
3696 * i960-tdep.c (examine_prologue): Add new argument limit,
3697 which stops the scan at the end of the prologue, or at the PC.
3698 This fixes a problem where it walks down into the code for the
3699 user's statements if that code looks like function prologues.
3700 Mark Fox and I have been bouncing this code back and forth, making
3701 small changes to it. Callers changed to match.
3703 Tue Feb 26 01:47:07 1991 Cygnus John Gilmore (cygnus at yuba)
3705 Cleanup for gdb-3.94 release final:
3707 * Makefile.dist: Remove remote-vx.c, remote-nindy.c, and all
3708 the .c files from vx-share and nindy-share, from the various
3709 macros, since they are not found via ALLDEPFILES.
3710 (SFILES): Add tm-i960.h.
3711 (alldeps.mak rule): Break out ALLDEPFILES_MAINDIR and
3712 ALLDEPFILES_SUBDIR. List all the nindy and vxworks subdir files
3714 (TAGFILES_MAINDIR): Change ALLDEPFILES to ALLDEPFILES_MAINDIR.
3715 (gdb.tar.Z): Use ALLDEPFILES_SUBDIR as well as SFILES_SUBDIR.
3717 Mon Feb 25 16:02:35 1991 Cygnus John Gilmore (cygnus at oldman)
3719 * am29k-tdep.c: Add contribution line.
3720 (examine_prologue): Cache information about function prologues in
3721 the misc-function-vector to avoid lots of references over the
3722 serial line while examining instructions.
3724 * core.c (core_close): New function made from cleanup_core.
3726 * core.c, exec.c, inftarg.c, remote-eb.c, remote-nindy.c,
3727 remote-vx.c, remote.c, target.c, target.h,
3728 Update target_ops vector to add attach, close, and load entries.
3729 Use add_syms_addr_command, not add_file_addr_command, for
3730 add_file. Break out close routine from existing code.
3732 * dbxread.c (really_free_pendings): Don't free pending_blocks;
3733 they are in an obstack.
3734 (read_dbx_symtab): Relocate end_of_text_addr in the psymtab.
3736 (define_symbol): Add symbol type parameter; change callers;
3737 pass type parameter to DBX_PARM_SYMBOL_CLASS macro to allow
3738 it to influence the symbol class on the i960.
3739 (define_symbol): Swap LOC_CONST's into target byte order.
3741 * exec.c (exec_close): New function.
3742 (exec_file_command): Call it.
3744 * findvar.c (read_relative_register_raw_bytes): Doc byte order,
3745 Fix byte order of frame pointer.
3746 (read_var_value): Result of 0 if var's value can't be found,
3747 e.g. missing FRAME_ARGS_ADDRESS. Byte-swap LOC_CONST and
3748 LOC_LABEL values to target order. Add LOC_LOCAL_ARG.
3749 (locate_var_value): Use read_var_value and use its lazy address
3750 as the location of the var's value. Lint.
3752 * i960-pinsn.c (next_insn): Add routine from vxgdb for scanning
3755 * i960-tdep.c (arg_address, i960_frame_find_saved_regs): Remove
3756 obsolete Intel versions in favor of vxgdb versions.
3757 (check_host, byteswap, byteswap_val, reorder_val): Eliminate
3758 code dealing with byte order of values, which Intel did in host byte
3759 order rather than gdb-4's target byte order.
3760 (i960_frame_chain_valid): Move to nindy-tdep.c.
3761 (examine_prologue, skip_prologue, frame_find_saved_regs,
3762 frame_args_address, leafproc_return, saved_pc_after_call,
3763 pop_frame): Add vxgdb versions from Mark Fox.
3764 (examine_prologue, frame_struct_result_address): Add code
3765 to deal with the saved value of G13 (struct return address
3767 (frame_args_address): Modify Mark's version to prefer the
3768 saved value over the current value in the topmost frame.
3769 Cache result in the frame info to avoid performance hair in
3771 (print_fault): Add gdb960 code for printing faults.
3772 (_initialize_i960): Actually call check_host.
3774 * ieee-float.c (ieee_extended_to_double, ieee_double_to_extended):
3775 add stub routines. FIXME, these currently just return zero!
3777 * infcmd.c (program_info): Use PRINT_RANDOM_SIGNAL.
3778 (attach_command): Call target_attach, not target_open, now.
3780 * infrun.c (normal_stop): Make global, not static, for vx_attach.
3781 (child_attach): Rename from child_open.
3782 (wait_for_inferior): Use PRINT_RANDOM_SIGNAL. If stop_pc is zero,
3783 don't confuse it with a zero step_resume_break_address.
3785 * inftarg.c (child_detach): Eliminate inferior_pid test.
3786 (child_files_info): Clean up message a bit.
3787 (child_ops): Use child_attach, not child_open, to attach.
3789 * mem-break.c: #ifdef out the whole file if BREAKPOINT is not
3790 set (e.g. on VxWorks or NINDY). Move read_memory_nobpt from
3791 findvar.c to here, since it depends on the contents of the
3792 shadow_contents of breakpoints, but keep if #if 0 since it is
3795 * nindy-tdep.c: New file, contains nindy_frame_chain_valid, moved
3798 * printcmd.c (address_info): Handle LOC_LOCAL_ARG. Lint.
3799 (ptype_command, display_command): Eliminate have_inferior_p and
3800 have_core_file_p in favor of target_has_stack or
3801 target_has_execution.
3802 (print_frame_args): Handle LOC_LOCAL_ARG. Eliminate duplicate
3803 code for actually finding the values of arguments, though we still
3804 keep track of the maximum stack offset for use in printing unnamed
3805 arguments. Handle missing FRAME_ARGS_ADDRESS.
3807 * remote-nindy.c (i960_print_fault): Move to i960-tdep.c.
3808 (struct nindy_regs): Define registers passed to/from nindy.
3809 (nindy_fetch_registers, nindy_store-registers): Translate between
3810 nindy and GDB formats for the registers.
3811 (dcache_init): Statically allocate the cache, since it was being
3812 allocated by a malloc that was never freed anyway.
3813 (nindy_create_inferior): Error, not core dump, if no exec file.
3814 (nindy_before_main_loop): Use target_load, not target_add_file.
3816 * remote-vx.c (net_load): Specify large timeout for load
3817 requests. Allow user to break out with INTERRUPT.
3818 (net_break): Remove useless code, clean up. Change callers.
3819 (parse-args, skip_white_space, find_white_space): Clean up arg
3820 parsing to cope with quoted strings.
3821 (net_wait, net_quit): Never call error, just return status.
3822 (vx_read_register, vx_write_register): Cleanup status checking.
3823 #ifdef the code based on which CPU we are using (960 or 68k),
3824 FIXME, this should be completely general but it isn't yet.
3825 (vx_xfer_memory, vx_resume): Cleanup status checking.
3826 (vx_run_files_info): Improve message.
3827 (vx_load_command): Renamed from vx_add_file_command. Allow load
3829 (net_ptrace): Remove unused routine.
3830 (vx_wait): Adopt code from vxgdb960 to cope with broken
3831 connections to target machine and prompt to disconnect. Remove
3832 debug printouts. Map some EVENT_'s to SIGnals.
3833 (add_symbol_stub, vx_open): Print names of object files we found,
3834 and "ok" if we read their symbols OK. Clarify output in general.
3835 (vx_attach, vx_detach, vx_kill): Add these commands.
3836 (vx_convert_from_virtual, vx_convert_to_virtual): Simplify.
3837 (vx_run_ops): Turn off all_mem, to avoid spurious msg in the
3838 "info files" output, and create_inferior, since we already have
3841 * stack.c (frame_info): Replace Frame_unknown with 0.
3842 (print_frame_arg_vars): Handle LOC_LOCAL_ARG.
3843 (return_command): Pop until the PC matches as well as the FP,
3844 so it works even if the FP is shared with another function,
3845 as in "frameless" or "leaf" procedures.
3847 * symfile.c (load_command): renamed from add_file_target_command.
3848 (add_syms_addr_command): renamed from add_file_addr_command.
3849 (add_syms_command): Stub to call target_add_syms.
3850 (_initialize_symfile): Change command names and descriptions,
3851 add-file => add-syms, and load from alias to its own command.
3853 * target.c (kill_or_be_killed, maybe_kill_then_attach,
3854 maybe_kill_then_create_inferior): Default for attempts to start
3855 a process, if one is already running, is to ask about killing
3856 it and retry if yes.
3857 (upstack_create_inferior): #if-0 it, strata obsolete it.
3858 (push_target, unpush_target, pop_target): to_close() a target
3859 before unstacking it.
3860 (target_info): Renamed from target_files_info.
3861 (_initialize_targets): Rename "i files" as "i target", accessible
3864 * target.h: Improve comments about the target_ vectored routines.
3866 * tm-i960.h: Remove NINDY-specific stuff to tm-nindy960.h.
3867 Convert commenting style to standard GNU style.
3868 (DBX_PARM_SYMBOL_CLASS): allow LOC_LOCAL_ARG's to be recognized.
3869 (SKIP_PROLOGUE): No longer a no-op.
3870 (SAVED_PC_AFTER_CALL): Now handles leaf procedures.
3871 (*_REGNUM): Sort register numbers.
3872 (REGISTER_BYTES, REGISTER_BYTE, REGISTER_RAW_SIZE,
3873 MAX_REGISTER_RAW_SIZE, REGISTER_CONVERTIBLE,
3874 REGISTER_CONVERT_TO_VIRTUAL, REGISTER_CONVERT_TO_RAW): Float regs
3875 are now 10 byte extendeds, not 8 byte doubles.
3876 (FRAME_CHAIN_VALID): Make this config-dependent, since it differs
3877 for nindy versus vxworks targets. FIXME, this should possibly go
3878 in the target vector.
3879 (EXTRA_FRAME_INFO, INIT_EXTRA_FRAME_INFO): Cache both
3880 frame_saved_regs and arg pointer with each frame.
3881 (FRAMELESS_FUNCTION_INVOCATION): New leafproc support.
3882 (FRAME_ARGS_ADDRESS): Use cached result.
3883 (FRAME_ARGS_ADDRESS_CORRECT): New, avoids g14 guessing.
3884 (FRAME_FIND_SAVED_REGS): Change arg to subsidiary fn.
3885 (PRINT_RAMDON_SIGNAL): Call print_fault.
3886 (POP_FRAME): Now works.
3888 * tm-nindy960.h: Break this off tm-i960.h. NINDY-specific
3889 option parsing and startup; STACK_END_ADDR, FRAME_CHAIN_VALID,
3890 BREAKPOINT, and DECR_PC_AFTER_BREAK are here.
3891 (ADDITIONAL_OPTION_HANDLER): use target_load, not
3894 * tm-vxworks960.h: Break this off tm-i960.h. VxGDB specific
3895 startup; DECR_PC_AFTER_BREAK, and FRAME_CHAIN_VALID are here.
3897 * valarith.c (value_subscripted_rvalue): Avoid handling
3898 floats and doubles specially; it gave alignment errors. Lint.
3900 * valops.c (value_of_variable, value_of_this): Error if unknown
3903 * valprint.c (print_floating): Bcopy rather than pointer-deref,
3904 to avoid alignment problems.
3905 (value_print): Handle unknown value address.
3906 (cplus_val_print): Two args are ignored; remove them. Change caller.
3907 (val_print): Use unpack_long rather than pointer-deref.
3910 (unpack_long, unpack_double): Use bcopy rather than pointer-deref
3911 to avoid alignment problems.
3912 (value_being_returned): Error if return value unknown.
3913 (set_return_value): Add bogosity warning, FIXME. *
3915 * TODO: A woman's work is never done.
3917 * Makefile.dist: Distribute REMOTE_OBS into tconfig files.
3918 Separate INCLUDE_CFLAGS for use with lint. Add LINTFILES.
3919 Add ieee-float.o to OBS.
3920 * tconfig/{nindy960,vxworks68,vxworks960}: Include the desired
3921 REMOTE_OBS remote-interface files in the TDEPFILES and TM_FILE.
3922 * tconfig/i960: FIXME. Half-merge, produce warning if config'd.
3924 Changes to generalize the VxWorks RPC protocol slightly, to handle
3925 i960 as well as 68000.
3927 * vx-share/dbgRpcLib.h (VX_SOURCE_STEP): Add.
3928 * vx-share/reg.h: Produce i960 regs #ifdef I80960
3929 * vx-share/xdr_ptrace.c: Skip FPA registers if 960.
3930 * vx-share/xdr_rdb.h: Add SOURCE_STEP struct and xdr decl.
3931 * vx-share/xdr_rdb.c: Add xdr_SOURCE_STEP routine.
3932 * vx-share/xdr_regs.c: Add xdr_regs, xdr_fp_status, xdr_ext_fp
3933 for i960. Change xdr_vectors to xdr_opaques for 68k registers,
3934 so they will move in target byte order rather than network
3935 byte order (happens to be the same).
3937 Mon Feb 25 03:41:44 1991 John Gilmore (gnu at cygint.cygnus.com)
3939 * tm-convex.h (END_OF_TEXT_DEFAULT): Remove #if 0'd block.
3941 Sun Feb 24 00:55:53 1991 John Gilmore (gnu at cygint.cygnus.com)
3944 Add contribution lines to various files, showing where they
3947 * breakpoint.c (break_insn, check_break_insn_size,
3948 read_memory_nobpt): Remove to mem-break.c.
3950 * xm-*.h, param-no-tm.h, tm-29k.h, valprint.c: Change BYTE_ORDER to
3953 * tm-29k.h (STAB_REG_TO_REGNUM): Warn user if symbol table
3954 entry has bad register number. This change is not
3955 tested in this release, FIXME.
3957 * frame.h: Eliminate Frame_unknown in favor of a simple zero.
3960 * value.h: Force value's contents field to be aligned to hold
3961 at least a double or a long long (if supported). This avoids
3962 doing bcopy's in and out of the contents field.
3964 (step_1): Avoid coredump under obscure circumstances when we
3967 * symtab.h (misc_info): Add field to misc function vector for
3968 any kind of cached information the target code desires. AMD
3969 29000 uses this to avoid repeating examine_function_prologue's.
3971 * coffread.c: Lint. Remove static symfile, read_section_header.
3972 core.c (have_core_file_p): Lint: remove.
3973 expprint.c (print_subexp): Lint.
3974 infptrace.c, valops.c, valprint.c: lint.
3976 Roll in changes from vxgdb-5.0.1:
3978 * symtab.h: Comment byte order of each address class. Add
3979 LOC_LOCAL_ARG for frame-relative args (960).
3980 expread.y: Use LOC_LOCAL_ARG where LOC_ARG is used.
3981 symtab.c, symmisc.c: ditto.
3983 * infrun.c (init_wait_for_inferior): Clear stop_signal.
3985 * remote.c (remote_resume): Error if resume with a signal.
3987 * symfile.c (prim_record_misc_function): Clear misc_info.
3988 (fill_in_vptr_fieldno): Check stub type of arg.
3990 * valops.c (value_cast): Avoid looking up names of types whose
3991 name we don't know, to prevent coredump. Sun CC produces typedef
3992 rtx and the name of *rtx is zero...
3994 Mon Feb 18 21:16:25 1991 John Gilmore (gnu at cygint.cygnus.com)
3996 Roll in changes from final AMD 29000 port (Tiemann).
3998 tconfig/am29k: Add COFF_ENCAPSULATE and TARGET=TARGET_AM29K
3999 for ../include/a.out.encap.h. This might not work now that BFD
4000 is separately compiled. Instead, BFD support for encap will have
4001 to translate machine type 29k into the right COFF_MAGIC.
4003 * infcmd.c: Remove references to inferior_pid that aren't used
4004 in actual ptrace calls; use target_has_execution, etc.
4005 (have_inferior_p): Remove function.
4006 (program_info): Print target info rather than "process number";
4007 avoid gratuitous messages unless from_tty.
4008 (run_stack_dummy, finish_command): Set proceed_to_finish.
4009 infrun.c: Remove inferior_pid refs. Decl & init proceed_to_finish.
4010 main.c: Lint. Lose have_inferior_p().
4011 inferior.h (have_inferior_p): Remove, lint.
4012 (proceed_to_finish): Add flag to ask that all regs be saved
4013 by normal_stop, for the few commands that need it, speeding up
4014 serial I/O. Add comments to stop_registers.
4016 * remote-eb.c: Remove newline from breakpoint message we grep
4017 for. Never time out when running the user program.
4021 Wed Feb 13 15:34:40 1991 John Gilmore (gnu at cygint.cygnus.com)
4023 Roll in changes from vxgdb-5.0.1:
4025 * dbxread.c (read_dbx_symtab): If we encounter a "FORTRAN COMMON"
4026 symbol in its raw form, we are processing an unlinked ".o" file.
4027 See if the target environment has assigned it an address, using
4028 target_lookup_symbol (VxWorks does), and enter it into the symtab
4031 * tm-vxworks.h (FRAME_CHAIN, FRAME_CHAIN_VALID): Override usual
4032 68k versions for a simpler version that assumes zero FP at bottom.
4033 Fixes bug of truncated stack reports.
4035 * target.h (target_lookup_symbol): Define this routine's args
4036 and result, finally.
4038 * target.c (nosymbol): Default routine for target_lookup_symbol.
4039 (target_default): Default lookup_symbol and call_function too.
4040 (files_info): Only print has_all_memory warning if a non-dummy
4043 * remote-vx.c (vx_read_register, vx_convert_to_virtual,
4044 vx_convert_from_virtual): If target does not have floating point,
4045 zero register "values", and avoid doing cross-net conversions.
4046 (vx_lookup_symbol): Rename net_lookup_symbol, add to vectors.
4047 (vx_open): Rearrange code that attaches to target and reads
4048 symbols for all loaded modules, to work if some of the modules
4049 are not accessible. Add symbol_stub() and add_symbol_stub()
4050 as callbacks from catch_errors(). Allow connect attempt to be
4051 interrupted painlessly with ^C (FIXME, there are still some bugs
4052 if the interrupt happens during symbol reading.). Print
4053 final message with puts_filtered, since symbol messages are
4058 * main.c (catch_errors): Only print errstring if non-null.
4059 (command_loop): Avoid an ioctl per command to test ISATTY.
4061 * remote-vx.c (net_load): make static; avoid sophomoric msg.
4062 (vx_xfer_memory): Return correct result!
4063 (vx_files_info): Indicate whether target has float or not.
4064 (vx_lookup_symbol): Complain, not error, if target gone.
4065 (vx_open): Print "Connected" msg before disabling immediate-quit.
4066 [FIXME: lookup_symbol and vx_open changes need testing.]
4068 target.c, remote-eb.c, inftarg.c, am29k-opcode.h, target.h,
4069 tm-29k.h, tmm-vxworks68.h, symfile.c, gdb-int.texinfo: Add
4070 contributor lines and update copyrights to 1991.
4072 Changes from an attempted H-PUX host port:
4074 * infptrace.c (PT_ATTACH, PT_DETACH): Handle HP/UX, which
4075 defines PT_ATTACH and PT_DETACH but not PT_KILL.
4076 * remote-eb.c (eb_open): Misplaced endif kills sysv H/PUX.
4077 * remote-vx.c: include <sys/time.h> for HPUX.
4078 * hp300hpux-xdep.c (fetch_core_registers): Rewrite old
4079 "core_file_command" routine to BFD regime. May not work yet.
4081 Attempted port of "gdb-3.4 Van Jacobson xgdb" to modern gdb.
4083 * xgdb.c: Replace X10 version with some VJ version.
4084 (FIXME: Its copyright assignment is not on record.)
4085 * xgdb.c: Update include files to X11R4 (Xaw crud).
4086 (xgdb_display_source, create_text_widget): fix call to
4087 get_filename_and_charpos. Rewack source window stuff for X11R4
4088 (gleaned from include files, and "nm's" of binary libraries, since
4089 I had no doc available).
4090 (append_selection, append_selection_word): Disable with FIXME
4091 since R4 changed interface here.
4092 (create_buttons): Add back the old set of buttons.
4093 (xgdb_create_window): Fix call to XtInitialize (&argc not argc).
4095 * Makefile.dist (xgdb, xgdb-init.c): Update for X11R4 on Suns.
4096 Roll VERSION to 3.94 (not yet final though).
4098 Sat Feb 9 09:46:25 1991 John Gilmore (gnu at cygint.cygnus.com)
4100 * obstack.h (obstack_ptr_grow, obstack_ptr_grow_fast,
4101 obstack_int_grow, obstack_int_grow_fast): Eliminate
4102 cast on left of assignment, which gives MIPS cc fits and is
4105 * sparc-pinsn.c (print_insn): Eliminate 'set' test, subsumed by
4106 F_ALIAS. Use printf, not fprintf, when not passing a file
4108 (compare_opcodes): Check that identical instructions have
4109 identical opcodes, complain otherwise.
4111 * sparc-opcode.h (st %fsr): Fix opcode "lose" mask. This
4112 was reported by Roland McGrath.
4113 (unimp): Only match if exactly zero instruction. (Roland)
4114 (branches and traps): Generate all variations of these
4115 instructions with macros, based on a single call that defines
4116 each condition name and its binary representation.
4117 (set): Turn on alias bit, to avoid test in sparc-pinsn.c.
4119 * valprint.c (val_print_fields): Take, and use, format parameter.
4120 This means that "p/x struct" again prints the elements in the
4121 desired format. Changed callers.
4123 * stack.c (frame_info): Use filtered output, and indicate wrap
4124 points. Remove kludgy formatting designed to avoid line wrap.
4126 * utils.c (wrap_here): If the line is already full (because
4127 we had printed a long indent or long wrapped string), do an
4128 immediate newline-and-indent.
4130 * m68k-pinsn.c (print_insn_arg): Bugfix from
4131 ntmtv!thompson@ames.arc.nasa.gov (Mike Thompson): 'bkpt #0'
4132 instruction is incorrectly disassembled as bkpt #8.
4134 * dbxread.c (end_psymtab): Bugfix from Peter Schauer
4135 <pesrem@regent.e-technik.tu-muenchen.de>: If you want to set a
4136 breakpoint in a *.y file gdb will say Reading in symbols for *.y...
4137 and then will dump core (sometimes). I traced it back to an
4138 uninitialized symfile_name in psymtab_to_symtab.
4139 (const_vol_complaint): Add quotes to message.
4140 (define_symbol): Only believe line number if gcc_compiled.
4141 Avoid allocating symbol if we will not return it.
4143 Add target strata support so that newly established targets go
4144 into their right place in the target stack (e.g. a new exec file
4145 doesn't wipe out the ability to access the running process).
4147 * target.h, core.c, exec.c, inftarg.c, remote-eb.c,
4148 remote-nindy.c, remote-vx.c, remote.c, target.c: Add to_stratum
4149 and initialize it properly in all the targets.
4151 * target.h: Document strata. Change return type of push_target.
4153 * target.c (nomemory): new function for dummy memory access.
4154 (tcomplain): Rename complain, now also used in symfile.c.
4155 (push_target): Push targets within strata. New return value shows
4156 whether new target is on top of stack or not. Always keep dummy
4158 (target_files_info): Ignore dummy target.
4160 * core.c (core_open): Warn user, and skip accessing file, if the
4161 core target is not the topmost target in the stack.
4162 * remote-nindy.c (nindy_create_inferior): Avoid unpush_target, now
4165 * remote-vx.c: Remove vx_prepare_to_store from vxworks memory
4166 target_ops, it doesn't belong there since we have no regs there.
4167 Change name of target from machine => memory to clarify.
4169 Thu Feb 7 16:32:09 1991 John Gilmore (gnu at spiff.cygnus.com)
4171 * Freeze version 3.93 for release.
4173 * Makefile.dist: Handle vx-share and nindy-share subdirs
4174 properly when building gdb.tar.Z.
4176 * symtab.c: lint; add no_symtab_msg to consolidate the messages
4177 printed in various places, so I could change just one copy.
4179 * dbxread.c, coffread.c: Change references to bfd->iostream
4180 to cast to FILE *, now that BFD avoids needing types defined
4181 in other header files.
4183 Tue Feb 5 21:39:35 1991 John Gilmore (gnu at cygint.cygnus.com)
4185 * command.c, dbxread.c, expprint.c, infcmd.c, infptrace.c,
4186 infrun.c, printcmd.c, remote-nindy.c, source.c, sparc-tdep.c,
4187 sparc-xdep.c, symfile.h, symmisc.c, utils.c, valprint.c: Lint
4188 (actually gcc -Wall).
4190 * dbxread.c: Remove first_global_sym, last_global_sym, since
4191 they are never referenced.
4193 * defs.h (baud_rate): Declare.
4194 main.c: Define it, and add the -b option to set it.
4196 * gdb-int.texinfo: Add text on how to define a new host or target
4197 architecture, prompted by Per Bothner's questions about MIPS
4200 * gdb.texinfo: Document "complaints". Change doc of -q since
4201 gdb no longer prints the copyright and blurb if you specify a file
4202 name to be debugged (just like Emacs). Add doc for Nindy-specific
4203 command line flags for specifying target serial port and such.
4204 Update copyright to 1991.
4206 * gdbcore.h: Remove a large mass of now-useless crud, since BFD
4207 has taken over for us the job of ripping up executable files. The
4208 crud caused Per Bothner's port to not compile.
4210 * infrun.c (normal_stop): Avoid printing "Program exited
4211 normally" if we are in batch mode. This allows a GDB which
4212 executes a program on a target system, to behave like a Unix
4213 command (input from stdin, output to stdout, no extraneous
4216 * main.c (main): Allow additional machine-dependent command line
4217 options to be specified with the ADDITIONAL_OPTIONS,
4218 ADDITIONAL_OPTION_CASES, ADDITIONAL_OPTION_HELP, and
4219 ADDITIONAL_OPTION_HANDLER macros. Also allow machine-dependent
4220 processing to occur just before the main loop with
4221 BEFORE_MAIN_LOOP_HOOK.
4222 (main): If a "core file" argument is specified, and it is not a
4223 core file, try it as a process ID to attach.
4224 (symbol_completion_function): Attempt to cope with
4225 "show screen-" TAB, not very successfully. This needs more work,
4227 (batch_file): New function, returns whether we are reading
4228 commands from an interactive tty on stdin, or from somewhere else.
4229 Called by normal_stop since it doesn't get from_tty passed down
4230 to it like many commands do.
4232 * remote-nindy.c: Handle command line options for nindy
4234 (nindy_before_main_loop): Prompt user for tty name if they
4235 don't specify it before getting to the interactive command loop.
4237 * tm-i960.c: Add ADDITIONAL_OPTIONS, etc, to handle -O, -brk,
4238 and -r command line options. Also add hook before main loop
4239 to make it easy to specify a tty.
4241 * TODO: More things to do, one done.
4243 Mon Feb 4 23:57:39 1991 John Gilmore and Mike Tiemann (at cygint.cygnus.com)
4245 * dbxread.c: Make complaint() calls pass pointer, not struct.
4246 Add complaints about badly formatted C++ type information
4247 (const/volatile indicator, and parse errors resulting in
4248 error_type). Fix C++ virtual member fn comment.
4249 (read_struct_type): Avoid bumping pointer if we got a parse
4250 error; this prevents our walking beyond the end of a string.
4251 Terminate loop on null char as well as semicolon.
4252 (process_one_symbol): Fix the LBRAC fix so that it uses the
4253 last previous SLINE, FUN, or SO record's PC address. C++ debug
4254 symbols did not have SLINE records in a useful order compared
4255 to the LBRAC records.
4256 (define_symbol): Handle "catch" records.
4258 * symtab.c (check_stub_type): Added new complain
4259 `stub_noname_complain' and added a consistency check to
4260 keep the debugger from crashing when finishing from an
4261 exception frame. A real fix will be needed later.
4263 Sat Feb 2 10:43:05 1991 John Gilmore (gnu at cygint.cygnus.com)
4265 * infcmd.c (attach_command): Make global.
4267 * Makefile.dist (REMOTE_OBS): Make these compile by default,
4268 but make them easy to comment out. Perhaps later they should
4269 be enabled by what CPU you configure for? FIXME.
4270 (VERSION): Roll to 3.93.
4271 (pinsn.o): Remove rule for obsolete file.
4272 (dbxread.o,coffread.o,mipsread.o): Use ${srcdir} explicitly.
4274 Run down a problem that manifested by printing the wrong function
4275 name in stack traces of read_ofile_symtab. Turned out that the
4276 problem was the SunOS 4.1.1 (and previous) C compiler outputs
4277 the LBRAC symbol with an address in the *data* segment, which
4278 blew our binary search through the blocks.
4280 * dbxread.c: Use the complain() facility consistently to bitch
4281 about problems in the symbol file we are reading.
4282 (finish_block): Add code to check the nesting of the blocks;
4283 complain and Procrust them to fit if wrong.
4284 (make_blockvector): Check the order of the blocks, complain
4285 [but don't cope] if wrong.
4286 (process_one_symbol): ifndef SUN_FIXED_LBRAC_BUG, check LBRAC
4287 symbols to be sure their PC value is greater than the last SLINE
4288 (line number) symbol we've seen, complaining and adopting the
4289 SLINE PC value if wrong.
4291 * symfile.h (struct complaint, complaint_root, complain,
4292 clear_complaints): Add.
4293 * symfile.c (complain, complaint_root, clear_complaints): Add
4294 facility to deal with non-fatal complaints and to regularize their
4296 (symbol_file_add): Clear complaint counters to allow new complaints.
4297 (initialize_symfile): Add 'set complaints' and 'show complaints'.
4299 * dbxread.c (dbx_symfile_read): Remember the address and size
4300 of the string table for the main symbol file, so we won't read it
4302 (dbx_psymtab_to_symtab): Fix the check for main symbol file,
4303 to avoid reading the string table yet again. Lint.
4304 (throughout): Improve filtered output, including word wrap.
4305 (read_range_type): Improve Bothner's fix to handle other types too.
4307 * utils.c: Improve line wrap implementation. Handle unlimited
4308 width by making chars_per_line unsigned.
4309 (puts_filtered): New, easy, function.
4311 * defs.h (puts_filtered): add.
4313 * mipsread.c (compare_symbols, sort_symtab): Remove these fns,
4314 call the identical sort_symtab_syms() in symfile.c instead.
4316 * expread.y: Suggest the `file' command rather than `symbol-file'.
4318 * command.h (enum var_types): Add zinteger for seroable
4320 * command.c (do_setshow_command): Handle var_zinteger. Restructure
4321 nested if's into a switch.
4323 * breakpoint.c (bpstat_print): If bpstat "print" flag is not set,
4324 we did not stop because of a breakpoint (it must have been for
4325 some other reason, like a "stepi"), so don't print anything.
4327 * symtab.c: Include <sys/types.h> all the time. Now that BFD
4328 doesn't include <sys/types.h>, old SunOS's require it for
4331 Sat Feb 2 10:39:15 1991 Per Bothner (bothner@cs.wisc.edu)
4333 A test port of gdb-3.92.6 to the Sony NEWS.
4336 Don't normally link in remote- or vx stuff.
4337 Some of it doesn't compile, and it wastes space for 99% of the users.
4338 Remove reference to no-longer-used HAVE_VPRINTF.
4339 Fixed BFD_DEP typo to BFD_DIR.
4341 Fix cast in arg to bfd_h_getlong.
4342 Make char *prefix be const.
4343 Fix how certain range types are mapped into builtin unsigned int types.
4345 Remove 2 #includes. They cause errors (on Sony, at least),
4346 and aren't needed (they wern't in earlier versions).
4348 print_address_symbolic should never demangle labels
4349 (since it prints *assembler-level* labels).
4351 [This was superseded by the change to printcmd below.]
4354 Add some "volatile" return types to avoid warnings.
4355 If MISSING_VPRINTF add vprintf function and not just macro
4356 (since vprintf is used in printcmd.c).
4358 Unless __GNUC__, use obstack_grow instead of obstack_ptr_grow.
4359 (The latter isn't grokked by some PCC-based compilers.)
4361 [This change is in abeyance, we prefer to fix obstack_ptr_grow.]
4363 Make chunk size of dont_print_obstack 32*4 instead of default 4096.
4364 * nindy-share/coffstrip.c
4365 Added some forward declarations (otherwise, gcc complains
4366 about implicit extern redefined as static).
4368 Sun Jan 20 02:38:19 1991 John Gilmore (gnu at cygint.cygnus.com)
4370 Changes inspired by Per Bothner:
4371 * printcmd.c (print_address_symbolic): Take additional parameter
4372 specifying whether to demangle.
4373 (print_address): Pass in asm_demangle to control demangling.
4374 (print_address_demangle): New fn, takes explicit arg to control
4376 * utils.c: Add new vars demangle and asm_demangle, and let them
4378 (fputs_demangled): If !demangle, just print the argument.
4379 (fprint_symbol): If !demangle, just print raw symbol.
4380 * valprint.c (val_print): Call print_address_demangle rather than
4381 print_address, to cause demangling to depend on the global
4382 rather than assembler-level demangling setting.
4383 * WHATS.NEW, gdb.texinfo: Document.
4385 * main.c (show_command): Show all settings if no arg.
4386 (initialize_main): Make "info set" the same as naked "show".
4387 * command.c (cmd_show_list): Handle prefix commands in the
4388 list, and print the name of the setting as well as its English
4389 description and value.
4391 Allow gdb functions to specify where a line should wrap if it
4392 exceeds the size of a terminal line. Use it to make the output
4394 * utils.c (set_screen_width_command): New fn, mallocs a buffer
4395 of the right size when screen width changes.
4396 (set_screensize_command, screensize_info): Remove #if 0'd fns.
4397 (wrap_here): New fn, indicates a point in the output where we
4398 should wrap the line rather than just letting it overflow at a
4400 (fputs_filtered): Implement wrapping.
4401 (n_spaces): New fn, returns a pointer to N spaces.
4402 (print_spaces_filtered): Use n_spaces.
4403 * defs.h (n_spaces): Declare.
4404 * stack.c (print_frame_info): Wrap with 4-space indent after
4405 fn name and before filename and line number.
4406 * printcmd.c (print_frame_args): Wrap with 4-space indent
4407 before each argument name is printed.
4408 * valprint.c (value_print): Wrap with no indentation before
4410 (val_print_fields): Wrap with indentation relative to nesting
4411 level before each field name.
4412 (val_print): Wrap with nesting indentation before array elements.
4413 * command.c (do_setshow_command): Avoid extra newlines,
4414 wrap with 4-space indent around values printed, end with period.
4415 * WHATS.NEW, gdb.texinfo, gdb-int.texinfo: Document.
4417 * breakpoint.c (breakpoint_1): Implement addressprint for
4418 "info breakpoints" display. Change file name and line number
4419 format to " at file:nnn" rather than " (file line nnn)".
4420 * gdb.texinfo: Document.
4423 Fri Jan 18 07:21:25 1991 John Gilmore (gnu at cygint.cygnus.com)
4425 Frozen for gdb-3.92.6 release.
4427 README, WHATS.NEW: Update for 3.92.6 release.
4429 tconfig/{altos, i386v, i386v32, m88k, umax}: Eliminate
4430 coffread.o from configs since it is now built by default.
4431 tconfig/{3b1, altosgas, arm, convex, hp300bsd, hp300hpux,
4432 i386v-g, i386v32-g, isi, merlin, news, news1000, np1, pn,
4433 pyramid, symmetry, vax, vxworks68}: Eliminate dbxread.o
4434 from configs since it is now built by default.
4436 Makefile.dist: Update for release 3.92.6. Handle files that
4437 have been moved to ../include, ../getopt, or ../bfd. Add
4438 saber.suppress and tests directory. Add config.status to
4439 the release (it will say "none").
4441 coredep.c: Minor formatting fixes.
4443 These changes were made in early December but only checked in now:
4444 * nindy-share/Onindy.c, nindy-share/coffstrip.c,
4445 nindy-share/nindy.c: lint
4446 * nindy-share/nindy.c (ninStopWhy): Don't byteswap the
4447 register values coming back from the target; we store values
4448 in target byte order everywhere.
4450 Wed Jan 16 19:01:37 1991 John Gilmore (gnu at cygint.cygnus.com)
4452 * am29k-opcode.h, am29k-pinsn.c: Add 29050 opcodes.
4454 * valprint.c (cplus_val_print, val_print_fields): New functions,
4455 which print C++ objects. They conspire to avoid printing a
4456 virtual base class more than once, following all the twists and
4457 turns of C++ virtual base rules.
4458 (val_print): Call the above rather than do it by hand.
4460 * symfile.c (symbol_file_add): Only reset symfile_mtime for main
4461 symbol file, not for added files like shared libs. This really
4462 needs to be generalized to a timestamp per file.
4464 * core.c (cleanup_core): Avoid coredump if no core file.
4466 * config.gdb: Accept -host or -target in place of +host or
4469 * coffread.c (find_linenos): Avoid desupported BFD interface
4470 to line numbers. We still read them manually rather than using
4471 BFD's "generic" features.
4473 * gdbrc.tex, threecol.tex: Add GDB reference card and its
4475 Makefile.dist: Add refcard to OTHERS list for creating tar files.
4477 * Makefile.dist: Eliminate use of $< in explicit targets.
4479 * readline/Makefile: Use $< rather than $*.c, which does not
4480 include the VPATH in GNU Make.
4482 * tconfig/i960-bout, tconfig/i960-coff: These are identical
4483 copies of tconfig/i960, added for global configuration
4484 compatability. All i960 versions can read both coff and b.out.
4486 * tm-88k.h: Fix multiline macro that lacked \'s. Remove
4487 COFF_FORMAT and COFF_CHECK_X_ZEROES since these are now handled
4490 * TODO: Think of more things to do.
4492 Wed Jan 2 19:09:29 1991 John Gilmore (gnu at spiff.cygnus.com)
4494 tconfig/{am29k,i960,sun2*,sun3*,sun4*}: Eliminate config
4495 of sdb versus dbx debug symbols. Add kludge for 68881 80-bit to
4496 64-bit float conversion.
4498 tconfig/sun4, tconfig/sun3, xconfig/sun4, xconfig/sun3: Make
4499 equivalent to sun?os4 so global config works.
4501 Wed Jan 2 18:20:51 1991 John Gilmore (gnu at spiff.cygnus.com)
4503 Fix from Eberhard Mattes <mattes@azu.informatik.uni-stuttgart.de>
4505 * main.c: Only declare linesize once; declare pagesize not at
4506 all, since it is never used.
4507 (main): Clear newly allocated line before it is used.
4509 Fri Dec 28 00:13:42 1990 John Gilmore (gnu at cygint)
4511 Further stabilization for the Intel 960.
4513 * Makefile.dist: Parameterize the location of the "include"
4514 and "bfd" directories, as well as "getopt". Add symfile.c.
4515 Link in both dbxread and coffread. Fix up "make depend" to
4516 rewack the locations of include, bfd, and getopt in its output.
4518 * README: Document moving include files, improve some of
4521 * coffread.c: Move common code out to symfile.c. Change
4522 symbol_file_command style interface to use new *_symfile_init
4523 and *_symfile_read interface under BFD. Use BFD internal
4524 info to locate line table, symbols, etc.
4526 * core.c (core_fetch_registers): Rename to get_core_registers
4527 to avoid confusion with fetch_core_registers.
4528 (register_addr): Move to coredep.c, which is already machine
4529 dependent. This leaves core.c pretty clean of dependencies.
4531 * coredep.c (register_addr): Accept this routine from core.c.
4533 * dbxread.c: Move common code (with coffread.c, etc) into new
4534 symfile.c. Each psymtab now contains a pointer to the
4535 format-dependent function that knows how to read it in. Make
4537 (dbx_psymtab_to_symtab): Renamed from psymtab_to_symtab_2.
4538 (process_one_symbol): Add code to complain about a "compiler bug
4539 we muzzle here", if we actually see it.
4541 * eval.c (evaluate_subexp): Insert missing "break" statements
4542 in code that determines whether a variable is an lvalue in
4543 memory, register, or whatever. I detected this via a compiler
4544 bug in which it *almost* mashed out the whole switch statement.
4546 * gdb-int.texinfo: Add minor sections on configuring gdb for
4547 release, and about the README file.
4549 * infcmd.c (registers_info): Fix formatting somewhat. Still
4550 not as pretty as before, but it handles byte swapping.
4552 * remote-nindy.c: If data cache routines are interrupted while
4553 waiting for the remote end, be sure that any uninitialized cache
4554 blocks are on the free list, not on the valid list!
4556 * symfile.h: Flesh out this header file with all the various
4557 routines and variables that have been merged in from dbxread.c
4558 coffread.c, and symtab.c to symfile.c.
4560 * symfile.c: New file, containing code common to dbxread.c,
4561 coffread.c, and some code from symtab.c. All generic code for
4562 reading symbol files should be in here now.
4563 (unrecord_misc_function): Remove unused function.
4565 * symtab.h: Remove file-reading things to symfile.h.
4567 * symtab.c: Remove file-reading things to symfile.c.
4569 * tm-i960.h: Fix FRAME_CHAIN types; define PRINT_RANDOM_SIGNAL
4570 to decode i960 fault types.
4572 * target.h, remote.c, remote-eb.c, remote-vx.c, remote-nindy.c,
4573 target.c: Change type of the "resume" function from int to void,
4574 since its result was never used.
4576 Sat Dec 22 02:51:40 1990 John Gilmore (gnu at cygint)
4578 * main.c: Replace "stupid" with "caution"; you now "set caution
4581 * printcmd.c (print_scalar_formatted): Fix typo in 'g' format
4583 * infcmd.c (do_registers_info): Call val_print to deal with the
4584 byte order of the registers being printed. FIXME, this makes
4585 the formatting of the output uglier.
4587 * infcmd.c (wait_for_inferior): If PRINT_RANDOM_SIGNAL is
4588 defined, call it for signals the debugger doesn't itself use.
4589 The i960 uses this for more detailed fault information.
4591 * remote.c (remote_open): If arg is null, print help rather than
4594 * sparc-xdep.c (register_valid): Avoid declaring size, since
4595 various modules will think of various sizes depending on the
4596 architecture of their tm-file. FIXME, we need protection against
4597 actually entering one of those modules, which would clobber
4598 storage if not for the target architecture compiled into gdb.
4600 * stack.c (up_command, down_command): Always print the frame
4602 (up_silently_command, down_silently_command): New commands
4605 * i960-pinsn.c (reg), i960-tdep.c: Lint.
4607 * i960-tdep.c (i960_frame_chain_valid): Lookup_symbol now takes
4608 more parameters than it used to.
4610 * findvar.c (registers): Increase slop to 256 bytes, which should
4611 protect us against even most RISC machines with large register
4613 (locate_var_value): Move declaration inside related ifdef.
4615 * remote-nindy.c (): Use TIOCSETN rather than TIOCSETP
4616 throughout, to avoid throwing away buffered input from the board.
4617 (nindy_wait): Supply_register takes addr_of_value, not value.
4618 (i960_print_fault): Renamed from i80960_fault.
4619 (nindy_fetch_registers): Avoid have_regs stuff, just get them.
4620 (nindy_store_registers): Avoid regs_changed stuff, just stuff
4622 (nindy_create_inferior): Don't bother to write PC_REGNUM since
4623 we can set the PC in the call to proceed(). Unpush nindy_ops
4624 before pushing it on top, to avoid message to user. Eliminate
4625 commentary from Unix machines that just misleads here.
4626 (reset_command): Fix error message to suggest target command.
4628 Wed Dec 19 11:03:56 1990 John Gilmore (gnu at cygint)
4630 Release 3.92.5 as frozen.
4632 Stabilize the merged release...with help from lint, Saber C,
4635 Everywhere: Add include files needed to declare return types
4636 of functions called.
4638 * gdb.texinfo: Roland Pesch is documenting gdb, glory be!
4640 * breakpoint.h: Add undeclared breakpoint functions, and some
4641 functions for display handling since I couldn't think of a better
4644 * breakpoint.c (insert_breakpoints): Make code for disabling
4645 shared library bkpts more likely to work. It's used when we
4646 rerun a program and stop before the shared library has been
4648 (breakpoint_cond_eval, bpstat_stop_status): Pass arg as int,
4649 cast from pointer, so it squeezes through catch_errors.
4650 (bpstat_stop_status): Fix logic broken some time ago. We now
4651 always create a bpstat if the stop address matches a breakpoint,
4652 even if we don't stop there -- just like the old code used to do
4653 before I got my fingers into it (sigh).
4654 (breakpoint_1): Print "ignore count" after "stop only if"
4655 condition, since that's how it actually works.
4656 (mention): Handle watchpoints as well as breakpoints.
4657 (watch_command): use set_raw_breakpoint and mention to do most
4658 of the work (and initialize all the fields!). Only pass one
4659 arg to parse_c_expression, since that's all it takes.
4661 * command.c (not_just_help_class_command): Rename arg to args
4662 since we ignore "unused argument" warnings on vars named "args".
4663 inflow.c (child_terminal_info): ditto.
4664 infptrace.c (kill_inferior): ditto
4665 main.c (catch_errors, version_info, quit_command, pwd_command,
4666 source_command, dump_me_command, editing_info,
4667 set_history_size_command, set_history, show_history,
4669 stack.c (locals_info): ditto
4670 target.c (target_files_info): ditto
4671 valprint.c (set_input_radix, set_output_radix): ditto
4673 * core.c: Remove old variables for handling core and exec file
4674 sections (data_start, data_end, stack_start, stack_end,
4675 reg_stack_start, reg_stack_end, reg_stack_offset, text_start,
4676 text_end, exec_data_start, exec_data_end, text_offset,
4677 exec_data_offset, data_offset, stack_offset). They're
4678 superseded the more general build_section_table and
4680 (get_exec_file): Mention the `file' command.
4681 (read_memory_check): Rename to memory_error, and only call it
4682 in the case of an actual error.
4683 (read_memory, write_memory): call memory_error.
4684 (core_fetch_registers): Register section name is ".reg".
4686 coredep.c: Remove a bunch of crud now that all this file does
4687 is pull the registers out of a core file.
4688 (fetch_core_registers): Rewrite to actually work, I hope.
4690 dbxread.c: Use a.out.gnu.h, not system a.out, now.
4691 Replace index() with strchr(). Remove all the pre-BFD macro
4692 definitions for accessing the symbol file.
4693 (struct dbx_symfile_info): Encapsulate the information that
4694 dbx_symfile_init needs to pass to dbx_symfile_read in this
4697 (dbx_new_init, dbx_symfile_init, dbx_symfile_read,
4698 dbx_symfile_discard): Rearrange symbol file reading to divide
4699 the format-specific part from the format-independent part,
4700 leaving the format-independent part such as file name expansion
4701 and opening in symtab.c. This replaces
4702 partial_symbol_file_open and partial_symbol_file_read.
4703 Symbol_file_read, add_file, add_file_target_command,
4704 add_file_addr_command move to symtab.c. Pass an explicit
4705 "mainline" flag for when reading the main symbol table, rather
4706 than relying on the offset address to be zero or nonzero.
4708 (dbx_symfile_read): Don't allow void *'s to be printed as
4710 (SWAP_SYMBOL): Use bfd routines to byte-swap the symbols.
4711 (ADD_PSYMBOL_TO_LIST): Make the "function call rather than
4712 macro" debug version really work.
4713 (read_dbx_symtab): Remove unref'd parameter inclink.
4714 Avoid swapping N_SLINE symbols, for speed.
4715 Merge N_TEXT!N_EXT case with the other external symbol
4716 definitions' case. Add comments.
4717 (start_psymtab): Allocate the symfile name in the psymtab on
4718 the psymbol_obstack, rather than using the caller's storage.
4719 (end_psymtab): Only allocate a dependencies list if there are
4721 (psymtab_to_symtab_2): Use BFD when reopening file to read
4722 its symbols for real.
4723 (read_struct_type): Add FIXME comments where it needs work
4725 (read_huge_number): Add FIXME about overflows.
4726 (read_range_type): Add FIXME about comparing a long to 1<<32.
4728 * coffread.c: Minor changes to move things closer to the new
4729 regime with symtab.c and dbxread.c Major work is still needed
4732 * exec.c (exec_file_command): Remove old variables (see core.c
4734 (xfer_memory): If memory transfer is right at the end of a
4735 section, don't lose.
4737 * findvar.c (get_saved_register): If value is in a real
4738 register, LVAL is lval_register, not lval_memory.
4740 frame.h: Declare print_sel_frame and record_selected_frame.
4742 gdb-int.texinfo: New file, for GDB internals documentation.
4743 Very simple, unformatted doc of cleanups is there for now.
4745 gdbcore.h: Remove obsolete variables that described a.out
4746 section addresses and offsets. (See core.c above.)
4747 Declare fetch_core_registers and registers_fetched.
4749 getopt.c: Declare char *alloca(); even on SPARC.
4751 infcmd.c (run_command): Call target_kill rather than
4753 (step_command, next_command, stepi_command, nexti_command):
4754 Declare from_tty parameter even though we don't use it.
4755 (run_stack_dummy): argument BUFFER is a char array, not
4756 a pointer to REGISTER_TYPE.
4757 (finish_command): using_struct_return needed a value *,
4758 not a struct symbol *.
4760 * infptrace.c (child_xfer_memory): To avoid dependency on
4761 where sections are in memory, try PT_WRITE_D and if that fails,
4762 try PT_WRITE_I. Most Unixes don't care which you use.
4764 * infrun.c (step_resume_break_shadow): Change to array to
4765 match other breakpoint shadow storage.
4766 (clear_proceed_status): Pass address of bpstat to
4767 bpstat_clear, not the bpstat itself.
4768 (child_create_inferior): FIXME comment about if the child
4770 (start_inferior): Remove old function.
4771 (child_open): Use target_kill rather than kill_inferior.
4772 (wait_for_inferior): Ditto.
4773 (insert_step_breakpoint, remote_step_breakpoint): Use
4774 new step_resume_break_shadow.
4776 * inftarg.c (child_wait): If all child processes die,
4777 pretend that the one being waited for exited with signal 42.
4779 * main.c (command_line_input): When scanning for comments,
4780 don't coredump on unclosed quotes.
4781 (quit_command): Use target_kill rther than kill_inferior.
4782 (_initialize_main): Rename class_user from "user" to
4785 * printcmd.c (print_command_1): Initialize "fmt" if no format
4786 is specified by the user.
4787 (print_frame_args): Only add to args_printed if we are
4788 actually fetching args from the stack (avoiding undefined
4790 (_initialize_printcmd): Remove bogus \{ from string.
4792 * remote-eb.c (eb_open): Avoid coredump on no argument.
4794 * remote-nindy.c: Bring out of Intel environment into new
4795 target environment. Remove all conditional compilation on
4796 I80960. Massive hacking throughout.
4797 (nindy_xfer_inferior_memory): New routine stolen from
4799 (nindy_create_inferior): New routine pieced together, probably
4800 not quite working yet.
4801 (nindy_ops): New target_ops struct for nindy.
4803 * remote-vx.c: Use write_memory rather than target_write_memory
4804 to get error checking.
4805 (vx_add_file_command, vx_open): Use symbol_file_add rather than
4807 (vx_create_inferior): Use target_terminal_ours...
4809 * signame.c (_initialize_signame): Always initialize, since
4810 we need the table for things other than psignal.
4812 * solib.c (solib_add): Use symbol_file_add, not add_file.
4813 (solib_address): Return boolean result rather than struct
4814 pointer which nobody else knows the type of.
4816 * sparc-tdep.c, valops.c: Use write_memory rather than
4817 target_write_memory, to get error checking.
4819 * stack.c (locals_info, catch_info, args_info,
4820 get_selected_block, frame_command, up_command): Use
4821 target_has_stack, rather than have_inferior_p or
4824 * sun3-xdep.c (fetch_core_registers): Rewrite for new BFD regime.
4826 * symfile.h: New file, defining the interface between the
4827 generic and object-file-specific symbol reading code.
4829 * symtab.c: Move generic symbol-reading interface to symtab.c,
4830 from dbxread.c, coffread.c, mipsread.c, etc. Add symtab_fns
4831 table to map BFD targets to symbol-reading modules in GDB.
4832 Change index to strchr.
4833 (lookup_struct_elt_type): Use error() rather than hand-made
4834 simulations thereof.
4835 (lookup_partial_symbol): Speedup slightly when length == 0.
4836 (symbol_file_add): New function.
4837 (symbol_file_command): Call it.
4838 (symfile_open, symfile_init): New function.
4839 (add_file_target_command, add_file_addr_command): moved from
4842 * target.c (target_command): use target_kill.
4844 * target.h (target_files_info): Don't declare, never called
4847 * tm-sun2.h, tm-sun3.h (STACK_END_ADDR): Use system include
4848 files to determine stack end address.
4850 * valarith.c (value_x_binop, value_x_unop): Change error message
4851 to be more useful. Pass proper argument to value_struct_elt.
4853 * valops.c (value_assign): FIXME comment that long long
4854 bitfields will break here.
4856 * Makefile.dist: Add symfile.h, remote-nindy.c, remote-eb.c.
4857 Update `make saber_gdb' to work better.
4859 * TODO: A woman's work is never done.
4861 * cplus-dem.c, environ.c, inferior.h, infrun.c, inftarg.c,
4862 main.c, obstack.c, printcmd.c, remote-eb.c, remote-nindy.c,
4863 remote-vx.c, remote.c, solib.c, source.c, sparc-pinsn.c,
4864 sparc-tdep.c, sparc-xdep.c, symmisc.c, symtab.c, symtab.h
4865 target.c, terminal.h, tm-sparc.h, tm-sunos.h, utils.c,
4866 valops.c, valprint.c, exec.c: Lint.
4869 Wed Dec 12 23:44:15 1990 John Gilmore (gnu at cygnus.com)
4871 Continuing Intel 960 port merge of GDB.
4873 * Makefile.dist: Merge i960 "nindy-share" files. Rename
4874 malloc.h to gmalloc.h to avoid name conflicts in /usr/include.
4875 Don't ship gdb.dvi in tar file. Link gdb with init.o, not init.c.
4876 Wack over "make depend" so it handles files in subdirectories
4877 vx-share, nindy-share, bfd, and in the current directory.
4879 * blockframe.c (get_prev_frame_info): Remove fatal error
4880 if stack not defined.
4882 * core.c (core_open, core_detach): New functions that handle
4883 the old "core-file" command as "target core" and "detach" instead.
4884 (core_file_command): Call them.
4885 (core_xfer_memory): Use common routine xfer_memory.
4887 * dbxread.c: Include a.out.gnu.h, not system a.out.h.
4888 dbxread now uses bfd for everything but symbol reading itself.
4889 BFD internals are used to drag out the relevant file offsets.
4890 (partial_symbol_file_open): Change args all around for BFD.
4892 * symtab.c: Rename "value" to "val" everywhere, so we can
4894 (symbol_file_command): New command, moved from dbxread.c
4895 and coffread.c. It uses BFD to read the file, then vectors
4896 based on its type, to dbx or coff symbol readers.
4897 * symtab.h: Extern a few vars for symbol_file_command.
4899 * target.h: Breakpoint takes a char * save area, not a char **.
4901 * valprint.c (val_print): When unpacking bitfields, offset
4902 the address in gdb of the value, if it is declared with a shorter
4903 type. Remove the last "runtime kludge test" of host byte order.
4905 * utils.c: Remove old my_bfd_read routine.
4907 * stack.c (frame_info): Use target_has_stack. Print program counter
4908 register's actual name rather than "pc", since it's called the
4909 "ip" (instruction pointer) on the i960 (sigh).
4911 * target.c (target_command): Add command for selecting a target
4912 type and calling its open routine. This is used for initiating
4913 communication with a particular target, in a generic way.
4915 * tm-i960.h: Update for modern gdb. Remove semicolons from
4916 various macros. Handle reading struct return convention, and
4917 error-out attempts to return structs with the "return" command.
4918 Be sure gdb doesn't think we know how to call functions in the
4921 * i960-tdep.c: Rename FRAME_CHAIN_VALID and FRAME_FIND_SAVED_REGS
4922 to i960_xxx in lower case.
4923 (arg_address): Circumvent errors due to LOC_ARG_BLOCK
4924 not being defined yet.
4926 * remote.c (remote_open): Call start_remote to initialize
4927 wait_for_inferior during open.
4928 (remote_xfer_inferior_memory): Return length written rather
4931 * remote-vx.c (target_command -> vx_open): Use new generic
4933 * remote-eb.c, inftarg.c, exec.c: ditto.
4935 * infrun.c: Fix comments.
4936 (attach_program -> child_open): Use new generic target command.
4937 (wait_for_inferior): Clear saved register values before target_wait,
4938 so target_wait can set some of them if convenient.
4940 * infptrace.c (fetch_inferior_registers, store_inferior_registers):
4941 Return success indicator, not void.
4942 (child_xfer_memory): Avoid fetching initial word if we'll
4943 overwrite it anyway.
4945 * infcmd.c (attach_command): Use new generic target open routine.
4946 (_initialize_infcmd): Update doc on attach and detach commands.
4947 (do_registers_info): Merge in a byte-order problem as a FIXME
4950 * findvar.c (find_saved_register): Avoid problem in current frame.
4951 (read_relative_register): Ditto.
4952 (write_register): Convert byte order on the way out.
4954 * exec.c (file_command): Add.
4955 (add_to_section_table, exec_command): Use new bfd_map_over_sections.
4956 (xfer_memory): Common function between core_xfer_memory and
4958 (exec_xfer_memory): Use it.
4960 * pn-opcode.h: Document that a "PN" is a Gould PowerNode.
4962 * breakpoint.c, breakpoint.h, symtab.h, value.h, frame.h, utils.c,
4963 valops.c, stack.c, target.c, sparc-xdep.c, source.c, printcmd.c,
4964 infcmd.c, i960-pinsn.c, eval.c, defs.h: lint and gcc -Wall.
4966 Sun Dec 2 16:45:06 1990 John Gilmore (gnu at cygnus.com)
4968 Merge Intel 960 port of gdb, continuing...
4970 * dbxread.c (partial_symbol_file_open, partial_symbol_file_read,
4971 symbol_file_command): Pass from_tty arg to hush 'em up.
4973 * coffread.c (symbol_file_command): Avoid output if from_tty != 1.
4974 Add magic numbers for 960 COFF format.
4976 Fri Nov 30 09:18:20 1990 John Gilmore (gnu at cygnus.com)
4978 Merge Intel 960 port of gdb, from Intel "1.2" release.
4980 CHANGE_LOG entries from their port, which was based on
4983 Thu Sep 6 11:02:22 PDT 1990
4984 Remove temp file if download is interrupted.
4986 Wed Aug 1 09:08:33 PDT 1990
4987 Now uses binary protocol to talk to NINDY.
4988 Old hex protocol (NINDY 2.13 and older) supported with -O switch.
4989 Times out after 5 seconds when trying to talk to NINDY.
4991 Tue May 29 12:54:49 PDT 1990
4992 Added variable baud rate (-b switch).
4993 Source code reorganization.
4995 Thu Apr 26 11:09:55 PDT 1990
4996 More cleanup of batch mode; specifically, execute "-s", "-e", and
4997 "-se" switches as soon as they are encountered on the invocation line.
4999 Fri Apr 20 13:47:15 PDT 1990
5002 Thu Apr 19 09:54:28 PDT 1990
5003 Add 'reset' command.
5005 Wed Apr 18 09:48:07 PDT 1990
5006 After opening remote tty, wait for 1 second to go by without input
5007 from it before trying to talk to NINDY (fixes problems with the
5008 Heurikon HK80/V960E).
5010 Mon Apr 4 16:33:05 PDT 1990
5011 Some output was not being suppressed in 'batch' mode.
5013 Thu Mar 22 15:31:11 PST 1990
5014 Ask user if old symbol table should be deleted when new file is
5017 Allow user to run a program downloaded before gdb960 was brought up.
5019 Correct "exec-file" help message for i80960 context.
5021 Correct bug in calculating user space address: could occasionally
5022 corrupt user program.
5024 Make sure to zero low-order bits in rip's because of bug in 960CA
5025 A-step part: could cause operation faults when "next"ing across
5028 Correct bug that made it impossible to get source line numbers for
5029 code loaded at addresses higher than 0x7fffffff.
5031 Wed Jan 10 12:43:22 PST 1990
5032 Open remote tty for exclusive use.
5034 Fri Jan 5 12:14:42 PST 1990
5035 Correct disassembly (CA manual was right after all):
5036 opcode for sysctl is 0x659
5038 Mon Oct 23 12:03:04 PDT 1989
5039 Use G960BASE and G960BIN environment variables to find 'sx' utility.
5041 Mon Oct 16 14:15:09 PDT 1989
5042 "sfr0"-"sfr31" should have been named "sf0"-"sf31"
5044 Mon Oct 2 15:56:31 PDT 1989
5046 Added 960CA disassembly support.
5048 To simplify maintenance:
5049 - eliminated use of symblic links on pinsn.c: use i960-pinsn.c
5051 - eliminated opcode.h: incorporates tables into i960-pinsn.c
5052 - moved 960-specific routines from i960-pinsn.c to i960-md.c
5053 - made disassembly interface identical to that in gdmp960.
5057 Wed Nov 28 21:32:48 1990 John Gilmore (gnu at cygint)
5059 * target.h: Allow targets to stack. Add target_has_memory,
5060 _registers, etc. Restructure memory access and "info files"
5061 to walk the target stack.
5062 * exec.c, core.c, inftarg.c, remote.c, remote-vx.c, remote-eb.c,
5063 target.c: Change tables to match target.h.
5064 * inflow.c (child_mourn_inferior): pop child_ops.
5065 (generic_mourn_inferior): Use new has_stack flag.
5066 * infptrace.c (child_xfer_memory): New memory regime.
5067 * inftarg.c (child_files_info): New "info files" regime.
5068 * remote-eb.c: New memory regime, new info files.
5069 * remote-vx.c: New memory regime, new info files. Now use
5070 separate targets for VxWorks attachment to machine, and
5071 actually running a process under VxWorks, since one has
5072 stack & execution & regs and the other doesn't.
5073 * remote.c: New memory regime, new info files.
5074 * sparc-xdep.c (fetch_core-registers): New memory regime.
5075 * target.c: New routines and support for stacked targets,
5076 new memory regime, new info files regime.
5079 Generalize section handling for an arbitrary number of sections,
5080 including use of the new BFD (binary file) library.
5081 * gdbcore.h: Add struct section_table.
5082 * exec.c (build_section_table): Iterate all sections and
5083 record what gdb needs to know about them.
5084 (exec_command): Use it.
5085 (exec_xfer_memory): Use the table.
5086 (exec_files_info): Print the table.
5087 * core.c (core_file_command, core_xfer_memory, core_files_info):
5089 * source.c (find_source_lines): Use bfd_get_mtime.
5090 * dbxread.c: Quick changes to make it compile with new BFD.
5091 * utils.c (error): Avoid using bfd_error in generic routines.
5093 * core.c (core_fetch_registers): Get from the ".regs" section of
5095 * sparc-xdep.c (fetch_core_registers): Use the .regs info.
5097 * inferior.h (attach_flag): Export.
5098 * infcmd.c (run_command): use new target_create_inferior.
5099 * infrun.c (child_create_inferior): Don't return result.
5100 * Makefile.dist (VERSION): 3.91.4.
5102 Fri Nov 23 28:15:38 1990 John Gilmore (gnu at cygint)
5104 * breakpoint.c (bpstat_num): Handle breakpoints which have
5105 since been deleted, such as temporary breakpoints.
5106 infcmd.c (program_info): ditto.
5108 * core.c (core_file_command): Display the frame where the core
5113 * remote-vx.c (target_command): Merge in target command from
5114 targ-vx.c. A few other cleanups.
5116 * TODO, Projects: Lots more stuff to do...
5118 Fri Nov 23 18:15:38 1990 John Gilmore (gnu at cygint)
5120 Massive changes to wall off the remote-debugging interface
5121 behind a function vector. The port to handle VxWorks targets
5122 is also part of this.
5124 All files: Replace references to renamed functions,
5125 remove references to remote_debugging, remove references to
5126 have_include_file, have_core_file in favor of target_has_stack,
5127 target_has_memory, etc.
5129 * Modularize the breakpoint interface.
5130 breakpoint.h (BREAKPOINT_MAX): New define sets max length of
5131 a breakpoint instruction.
5132 breakpoint.c: struct breakpoint's shadow_contents now sized as
5134 (insert_breakpoints): Vector to target to install breakpoints.
5135 (remove_breakpoints): Vector to target here too.
5136 Remove REMOTE_SA_SPARC kludges and other remote_debugging.
5137 sparc-tdep.c (single_step): Use new breakpoint interface for
5138 the single-step breakpoints.
5139 mem-break.c (memory_insert_breakpoint, memory_remove_breakpoint):
5140 New file, contains routines to insert and remove breakpoints by
5141 reading out the old contents and later replacing them. This is
5142 how ptrace breakpoints work, and many remote systems as well.
5144 * tm-vxworks68.h: New config file, overrides a few things for
5145 Wind River's preferences.
5147 * target.h: New file, for transfer vector used to talk to the
5148 inferior (child, attached, core, exec, remote, etc). All accesses
5149 to the thing being debugged should come through these vectors.
5150 target.c: New file, routines to handle transfer vector.
5151 (various files): Add transfer vectors XXX_ops for the various
5152 targets and pseudo-targets (core files, etc) we support.
5154 * breakpoint.c (bpstat_stop_status): Further explorations of
5155 watchpoints and why things don't work all the time.
5156 (bpstat_alloc): New fn to allocate a bpstat and chain it.
5158 * config.gdb: Only add "source ${srcdir}/.gdbinit" to
5159 the local gdbinit if it doesn't already have it.
5161 * core.c (core_ops): add and install.
5162 Allow core debugging without exec file.
5164 * dbxread.c (free_and_init_header_files): Merge two fns.
5165 (end_symtab): Free named symbol table when a new version comes in.
5166 (read_dbx_symtab): Relocate all kinds of symbols with base
5167 address. First step toward handling different text, data, bss
5169 (add_file_addr_command): Renamed add_file_command.
5170 (add_file_command): Vector to remote handler.
5171 Add "load" as an alias for "add-file" command.
5173 * defs.h: Allow "volatile" to be used in non-ANSI; use it for
5174 non-returning functions.
5176 * exec.c: Add exec_ops, and push it as a target when an exec
5179 * infcmd.c (run_command): Pass executable file name and arg list
5180 separately when starting an inferior. Permit "run" when no exec
5181 file is specified, for VxWorks.
5182 (detach_command): Move to child_detach in inftarg.c.
5184 * inftarg.c: New file. Unix-child-specific routines, and the
5185 child_ops structure.
5187 * inferior.h (registers): Export "registers" as the way for
5188 target dependent register handlers to find gdb's local copy of
5189 the registers. Rename "stop_after_attach" to "stop_soon_quietly"
5190 since it is now used by places that want wait_for_inferior to
5191 handle the grunge but want to see every trap from the inferior.
5193 * inflow.c (create_inferior): Pull out, and merge into infrun.c.
5194 Eliminate remote_debugging hooks in terminal handling.
5196 * infrun.c: Replace start_inferior with child_create_inferior.
5197 Move all the hair of Unix shells and ptrace idiosyncracies into
5198 child_create_inferior, so remote handlers don't have to deal.
5199 Remove running_in_shell. Rename stop_after_attach to
5200 stop_soon_quietly, and use it in a few other places where we want
5201 to just call wait_for_inferior and get control back on the first
5202 trap. trap_expected now never takes a value > 1.
5203 (init_wait_for_inferior): Initialize static vars when a new
5206 main.c (gdbinit): Add new hook for .gdbinit file name, let
5207 it be overridden by config files as GDBINIT_FILENAME.
5208 (DEFAULT_PROMPT): Add new hook for overriding (gdb) prompt.
5209 Both of these are used for VxWorks gdb.
5211 mcheck.c: rename include file "gmalloc.c" to avoid problems
5212 with system include file "malloc.c".
5214 param-no-tm.h: New include file, same as param.h but does not
5215 include the default "tm.h" file. This is used in files where
5216 the target is known, e.g. remote-eb.c or sparc-xdep.c.
5218 param.h: Now just a shell that includes tm.h and param-no-tm.h.
5220 remote-vx.c: New file, VxWorks remote debugging support. Uses
5221 RPC routines that are shared with the target system, in directory
5224 remote.c: Vectorize remote interface.
5226 source.c: Globalize source_path, and make an alias "l" for "list"
5227 since we now have the "load" command.
5229 sparc-xdep.c: Use new param-no-tm.h.
5231 symmisc.c (free_named_symtab): Add new function from Wind River.
5232 However, ifdef it out for now while we think about what it should
5235 tm-sun3.h, xm-sparc.h, xm-sun3.h, xm-symmetry.h: Move
5237 the xm- file, and change its name to CHILD_PREPARE_TO_STORE, since
5238 non-Unix-children handle this with their own code in the target
5241 Makefile.dist: Roll version to 3.92.3. Add vx-share stuff to
5242 source and target lists. Add vx-share to default list of include
5243 directories. Add new files to src and target lists: mem-break,
5244 target, inftarg, remote-eb, remote-vx, targ-vx. Be sure the
5245 ${srcdir} versions of munch and createtags are used.
5247 * valops.c (find_function_addr): Split out of call_function.
5248 (call_function_by_hand): Rename call_function; this function
5249 calls functions in the target by laboriously patching the target
5250 word-by-word with the right stack, args, regs, etc.
5253 Mon Nov 5 17:29:10 1990 John Gilmore (gnu at cygint)
5255 Handle AMD 29000 a bit better.
5257 * remote-eb.c (readchar): Mask received char log to make it readable.
5258 (remote_start): Pass arguments down to executing program.
5259 Make startaddr unsigned.
5260 infrun.c (start_inferior): Accept args, pass them to
5262 infcmd.c (run_command): Pass args down to start_inferior.
5264 * tconfig/am29k-aout, tconfig/am29k-coff: New files specifying
5265 the target object file format.
5266 tm-29k.h: Pay heed to COFF_ENCAPSULATE.
5268 * am29k-pinsn.c (print_insn): Print 0x on hex numbers in disassembly.
5269 am29k-tdep.c (examine_prologue): Better checking of function prefixes.
5271 Sun Oct 7 18:20:45 1990 John Gilmore (gnu at cygint)
5273 * Makefile.dist (VERSION): Roll version to 3.91.9 and freeze.
5274 * TODO: We did a few things, we have more to do though.
5276 * xm-sparc.h (CLEAR_DEFERRED_STORES): Define.
5277 * inflow.c (inferior_died): Clear deferred stores.
5279 * Debug problems with dummy frames and calls to the inferior.
5280 * tm-sparc.h (PUSH_DUMMY_FRAME, POP_FRAME): Move to sparc-tdep.c.
5281 * sparc-tdep.c (do_restore_insn): Simplify.
5282 (sparc_frame_find_saved_regs): Simplify and fix what we find.
5283 (sparc_push_dummy_frame): Simplify and fix what we push.
5284 (sparc_pop_frame): Slightly more hair here, deciding whether
5285 we are restoring a saved PC or returning to a return address in %i7.
5286 * sparc-xdep.c (read_inferior_registers): Debug if valid reg is read.
5288 * utils.c (xmalloc, xrealloc): Return type depends on __STDC__.
5289 * symtab.h (xmalloc): ditto, for obstack_chunk_alloc.
5290 * obstack.h (chunkfun): ditto.
5291 * defs.h (xmalloc, xrealloc): ditto
5293 * utils.c (quit): Grab the terminal from the child if necessary.
5295 * inflow.c (term_status_command): Rename to term_info, change
5298 * sparc-pinsn.c (print_insn): Disassembly prefers real instructions.
5299 (is_delayed_branch): Speed up.
5300 * sparc-opcode.h: Add ALIAS bit to aliases. Fix up opcode tables.
5301 Still missing some float ops, and needs testing.
5303 * Support for input and output radixes other than base 10
5304 * defs.h (input_radix, output_radix): Declare.
5305 * expread.y (yyparse, parse_number): Handle changes of input
5306 radix, and ambiguous names-or-numbers in radixes >10.
5307 * printcmd.c (print_scalar_formatted): Print formatted hex
5308 numbers in varying column widths.
5309 * valprint.c (val_print): Use output_format to print scalar ints.
5310 (set_input_radix, set_output_radix, set_radix): Create.
5311 (set_output_radix): Set output_format from output_radix.
5312 (_initialize_valprint): add `set radix' but leave the others off.
5314 * main.c (execute_command): Let stupid questions be turned off.
5315 (_initialize_main): Handle "set stupidity", etc.
5317 * main.c, inflow.c, inferior.h, frame.h, command.c, defs.h,
5318 sparc-pinsn.c, sparc-xdep.c, value.h, valops.c, values.c: Lint.
5320 Tue Oct 2 11:20:02 1990 John Gilmore (gnu at cygint)
5322 * TODO, Makefile.dist, ChangeLog: Freeze for 3.91.8 release.
5323 bfd stuff is still screwed up, but with some manual work, it
5326 * breakpoint.c (bpstat_do_actions): Start over if a command
5327 proceeds the inferior, since the inferior will have stopped and
5328 will need to have its new stop-actions taken care of.
5330 * dbxread.c (read_struct_type): Expression gives Sun3 4.0.3
5331 compiler fits, simplify it.
5333 * gdb.texinfo (directory command): Doc new dir command.
5334 source.c (directory_command): "dir" now puts things on the front
5335 of the path, moves dups up front, and handles multiple names
5336 on the command line, inserting each one in order. It also
5337 blows away cached line and full_filename info.
5339 * stack.c (backtrace_command): Skip "more stack frames follow"
5342 * Change #ifndef HAVE_VPRINTF to #define MISSING_VPRINTF in
5343 xm-convex.h, xm-hp300bsd.h, xm-isi.h, xm-merlin.h, xm-news.h,
5344 xm-np1.h, xm-pn.h, xm-pyr.h, xm-symmetry.h, xm-umax.h, xm-vax.h.
5345 The only odd one was Gould NP1, which had defined vprintf to
5348 * Merge Ted Goldstein <tedg@Eng.sun.com>'s changes for epoch.
5349 printcmd.c (print_command_1): Pass 'inspect' flag down as a global
5350 variable, inspect_it.
5351 valprint.c (print_string, val_print): Use the global inspect_it
5352 to indicate whether to print in Epoch style or normal style.
5354 Mon Oct 1 23:55:26 1990 John Gilmore (gnu at cygint)
5356 * printcmd.c (call_command): add an alias for the "print" command
5357 which runs expressions and doesn't print the result if void.
5358 (print_command_1): implement it.
5360 * command.c: Remove #if 0'd code. Initialize all the fields
5361 in add_cmd (). Rename do_nothing_command to
5362 not_just_help_class_command, and make it externally visible.
5363 command.h: add user_commands to struct.
5364 * main.c (define_command): Don't overload c->function with a char
5365 string as well as a function pointer.
5367 * eval.c (evaluate_subexp): Reinstall tiemann changes to
5368 calling convention of value_struct_elt () that got dropped in
5371 * tm-sparc.h (FRAME_FIND_SAVED_REGS): move to sparc-xdep.c.
5372 sparc-tdep.c (sparc_frame_find_saved_regs): ditto.
5374 * tm-sparc.h (POP_FRAME): replace some constants with defines.
5376 * sparc-xdep.c (store_inferior_registers): defer stores to regs
5377 until a good time (e.g. when we are about to run the child),
5378 saving ptrace calls.
5379 * infrun.c (proceed): handle DO_DEFERRED_STORES.
5380 * tm-sparc.h: define DO_DEFERRED_STORES.
5382 * sparc-xdep.c (store_inferior_registers): when storing float
5383 registers, don't store stack regs too. When storing the SP,
5384 however, DO store the stack regs too. This fixes a bug in which
5385 the dummy frame is not recognized when a call_function finishes,
5386 because its frame pointer (in the stack regs) was never
5388 (read_inferior_registers): Mark WIM and TBR and FPS and CPS valid
5389 even though we don't know how to read them from an inferior.
5390 valops.c (call_function): Comment about storing SP.
5392 * infrun.c (save_inferior_status): Save away the original bpstat
5393 chain so it can be restored later. Install the copied version for
5394 use by whoever saved the status. It will be blow away by
5395 restore_inferior_status, and the original chain restored. This is
5396 important for people who have pointers into the original.
5398 * breakpoint.c, command.h, copying.awk, dbxread.c, defs.h,
5399 findvar.c, frame.h, obstack.h, obstack.c, inflow.c, value.h,
5400 main.c, printcmd.c, sparc-tdep.c, symtab.c, valprint.c: lint
5403 Fri Sep 28 20:32:46 1990 John Gilmore (gnu at cygnus.com)
5405 * Makefile.dist: Roll version to 3.91.8. Add bfd.h and bfdconfig.h
5406 temporarily to the makefile. Add am29k-opcode.h and WHATS.NEW.
5407 Add stuff.c and kdb-start.c to the OTHERS list for tar files.
5409 Fri Sep 28 19:12:12 1990 John Gilmore (gnu at cygint)
5411 * Merge Mike Tiemann's multiple inheritance changes from Sun.
5412 Store the baseclasses in a type struct starting from array element
5413 0 rather than from the unusual array element 1.
5415 dbxread.c: the above.
5416 (virtual_context): Add
5417 Read new debug information about which virtual function table
5418 a virtual function is from, and store it in fn_field.fcontext.
5420 symtab.h: Add fcontextt. Fix baseclass indices. Typo in
5421 TYPE_FN_FIELD_STATIC_P.
5423 symtab.c: the above.
5424 valops.c: the above. Handle pointer casts of object *'s.
5425 (search_struct_method): Add.
5426 (value_struct_elt): First arg is now a pointer to a value, and is
5429 valprint.c: the above.
5430 values.c (value_virtual_fn_field): Add type arg. Handle
5431 offsetting to the proper object when calling virtual fns.
5433 (baseclass_addr): Add valuep arg.
5435 * README: Document the current state of BFD config (missing).
5436 * TODO, ChangeLog, Makefile.dist: Roll version.
5437 * WHATS.NEW: Add summary of changes since 3.5.
5439 Thu Sep 27 16:23:12 1990 John Gilmore (gnu at cygint)
5441 * dbxread.c (read_struct_type): Clear bit vectors whenever
5443 symtab.c (B_CLRALL): define.
5445 * tm-sparc.h (STORE_RETURN_VALUE): Avoid clobbering types by
5446 using == rather than =. Huh... This fixes the dreaded problem
5447 wherein builtin_type_int becomes TYPE_CODE_FLT.
5449 * core.c (info_files): Show the inferior pid.
5451 * config.gdb: Avoid putting "dir" command into .gdbinit. GDB
5452 already knows how to look in the source directory.
5454 * Remove psymtab hair from many places. Remove duplicated code
5455 for searching symbol tables. Hide psymtabs from most places.
5456 Make it fast to get from a psymtab to its symtab.
5458 blockframe.c (blockvector_for_pc): Remove psymtab hair.
5459 coffread.c (psymtab_to_symtab): Rename to psymtab_to_symtab2.
5460 mipsread.c (psymtab_to_symtab): Rename to psymtab_to_symtab2.
5461 dbxread.c: export psymtab_to_symtab, make it work if called N times.
5462 (psymtab_to_symtab): Rename to psymtab_to_symtab2. Initialize
5463 new symtab completely. New psymtabs get symtab pointer
5464 initialized to zero. Remove MI warning printf.
5465 symtab.h: Comments. Add psymtab to symtab pointer.
5466 (PSYMTAB_TO_SYMTAB): New macro.
5467 symtab.c: use PSYMTAB_TO_SYMTAB. Add psymtab_to_symtab and export it.
5468 source.c: use PSYMTAB_TO_SYMTAB. Remove symtab version and
5470 stack.c (backtrace_command): Avoid pre-pass to read symbols, if
5472 (print_frame_info): Avoid special-casing symbols that have not yet
5475 * source.c (open_source_file): Quick path if we have already
5476 located the source file by its full name.
5478 * symtab.c (lookup_symbol): Use find_pc_symtab rather than
5479 find_pc_psymtab. When a name is found in the misc function
5480 vector, search the symbol table for its mangled name, not the
5481 name that the user typed.
5483 * bfd.h: Fix missing comment terminators, make #endifs match.
5485 * valarith.c (value_less): Handle unsigned int comparisons.
5486 Add FIXME about pointer compares, which assume host and target
5487 pointers are the same.
5489 * command.c (do_nothing_command): lint
5490 dbxread.c: lint. Remove sort_syms. Document C++ visibility info,
5491 fix comments on debug symbol format for visibility. Actually set
5492 visibility of symbols.
5493 main.c (echo_command): lint; use <readline/history.h>.
5494 tm-sparc.h (FRAME_FIND_SAVED_REGS): lint
5495 obstack.h (_obstack_blank): Rearrange pointer math to avoid
5496 pointing past end of allocated memory; saber complains.
5497 obstack.h: Declare the external functions that we use.
5498 valarith.h: use <string.h>
5499 solib.c (solib_add): lint.
5501 Fri Sep 21 17:05:19 1990 John Gilmore (gnu at cygint)
5503 * main.c (initialize_main): Default info_verbose to off, now that
5504 symbol reading is fast.
5505 (quit_command): Avoid clobbering exec_bfd while quitting.
5507 * Initial BFD (binary file diddling library) merger:
5508 coffread.c: Change AOUTHDR to struct exe_hdr.
5510 core.c: initialize initialized data at compile time.
5511 (core_file_command): Move from coredep.c, convert to bfd.
5512 (xfer_core_file): Convert to bfd.
5513 exec.c (exec_file_command): use bfd routines.
5515 mips-tdep.c: Remove exec_file_command and friends.
5518 * coredep.c: (fetch_core_registers) Convert core_file_command to
5519 fetch_core_registers.
5520 mips-xdep.c, sparc-xdep.c, sun3-xdep.c: ditto.
5522 * utils.c: (error): Bogus crap, FIXME, to print bfd errors.
5523 (my_bfd_read): More bogosity, which I don't think we call.
5524 (program_name): Remove this atrocity asap!
5526 Wed Sep 19 13:36:41 1990 John Gilmore (gnu at cygint)
5529 values.c: allocate_repeat_value was not clearing the
5530 optimized_out field.
5531 (value_static_field): minor stylistic fix (wrong macro was used).
5532 valops.c (value_struct_elt_for_address): didn't work for C++
5535 * signame.c (_initialize_signame): Initialize signal names once.
5537 * breakpoint.h, command.c, copying.awk, defs.h, environ.c,
5538 exec.c, frame.h, infcmd.c, inferior.h, main.c, munch, sun3-xdep.c,
5539 symtab.h, tm-29k.h, valprint.c, value.h, values.c: Lint.
5541 * remote-eb.c: Support user-settable baud rates on the serial port.
5543 * tm-sun3.h (PREPARE_TO_STORE): fix typo.
5545 Fri Sep 14 13:28:29 1990 John Gilmore (gnu at cygint)
5547 * tconfig/sun3os4: Remove warning about native assembler,
5548 since it also occurs in the xconfig file.
5550 * findvar.c (registers): Allocate some slop after `registers'
5551 to prevent stray accesses from trashing the next variable.
5553 * tm-68k.h (REGISTER_BYTES): Allocate the right number of bytes
5554 on the sun-3, by changing the #ifdef from `sun3' (which is not
5555 defined by cc) to `sun'. Symptom was trashed builtin_type_XXX
5556 vars, which happened to follow `registers' in the executable.
5558 * readline/history.c (history_search): Heed gcc-2's advice
5559 and parenthesize && inside ||).
5561 * am29k-opcode.h, am29k-pinsn.c, am29k-tdep.c, remote-eb.c,
5562 tm-29k.c: Insert FSF copyright headers.
5564 * remote-eb.c: Better comments.
5566 * Makefile.dist: Update to 3.91.6.
5567 * TODO: note PREPARE_TO_STORE problem.
5569 Thu Sep 13 09:52:33 1990 Jim Kingdon (kingdon at cygint)
5571 * stack.c (frame_info): Only use FRAME_FIND_SAVED_REGS if defined.
5573 * remote.c: Wrap the whole file in #if !defined (SPECIAL_REMOTE).
5575 * infrun.c (wait_for_inferior, at end): Don't set up
5576 prev_* if the inferior no longer exists.
5578 * inferior.h (CALL_DUMMY_LOCATION): New macro, to replace
5579 CANNOT_EXECUTE_STACK.
5580 valops.c (call_function): Use it.
5582 * tm-convex.h: Add CALL_DUMMY_LENGTH for use by PC_IN_CALL_DUMMY.
5584 * inferior.h (PC_IN_CALL_DUMMY): New macro.
5585 infrun.c (wait_for_inferior, 2 places): Use it.
5587 * values.c (value_being_returned): Only use
5588 EXTRACT_STRUCT_VALUE_ADDRESS if defined.
5590 * Move PREPARE_TO_STORE from xm-sun3.h to tm-sun3.h to do the
5591 right thing for remote-eb.c.
5593 * sun3-xdep.c: Remove extraneous call to remote_store_registers.
5594 * sun386-xdep.c, hp300hpux-xdep.c, sparc-xdep.c: Ditto.
5596 * blockframe.c: Put get_frame_saved_regs inside #if !defined
5597 (FRAME_FIND_SAVED_REGS).
5599 * findvar.c ({fetch,store}_registers): Check for
5600 REMOTE_{FETCH_STORE}_REGISTER macro.
5602 * findvar.c (get_saved_register): Add argument lval and
5603 change meaning of argument addr.
5604 findvar.c: Change calls to get_saved_register to reflect
5605 new calling convention.
5606 valops.c (value_assign): Use get_saved_register instead of
5607 find_saved_register.
5609 Sun Sep 2 12:40:20 1990 Jim Kingdon (kingdon at cygint.cygnus.com)
5611 * coffread.c (read_one_sym): Make temp_aux an AUXENT, not
5612 an (uninitialized) pointer to one. Use "&" when passing it
5615 Fri Aug 31 22:57:54 1990 Jim Kingdon (kingdon at cygint.cygnus.com)
5617 * coffread.c (getfilename): Use DGUX x_offset and x_name if
5620 * coffread.c (symbol_file_command): Put semicolon after
5622 Put safe_to_init_tdesc_context in #if defined (TDESC).
5623 Put #ifdef TDESCs in 1st column for non-ANSI cpp's.
5624 coffread.c: #include <sys/stat.h>.
5625 (read_coff_symtab): Typo: in_source_files -> in_source_file.
5626 Add missing ')' in check for "lc%" and friends. Remove
5628 Declare read_one_sym() at top of file.
5629 (read_file_hdr): Put in extra #ifdefs so MC68MAGIC and
5630 MC68WRMAGIC can have the same value without causing a duplicate
5633 Thu Sep 13 15:55:36 1990 John Gilmore (gnu at cygint)
5635 * Allow a Makefile to be built without building the
5636 tm and xm file links that screw up builds in subdirectories.
5637 This is done with `config.gdb none', then you can do things
5638 like `make gdb.tar.Z'.
5639 * tconfig/none: Config file for no target system
5640 * xconfig/none: Config file for no host system
5641 * config.gdb: If no TM or XM files are called out by the
5642 host or target file, don't make links for them.
5644 * cplus-dem.c: Add documentation.
5646 * dbxread.c (read_ofile_symtab): Turn a fatal error into a
5647 simple error, so the user's gdb doesn't crash due to some object
5648 file problem (e.g. somebody is rebuilding the file out from under
5651 * printcmd.c (print_address_symbolic): demangle the symbol.
5653 * Makefile.dist (OTHERS): Remove tdesc-lib because it has
5654 Motorola copyrights in it. Make "make gdb.tar.Z" work.
5655 (alldeps.mak): sort and uniq all results from this; duplicates
5656 hose gdb.tar.Z link building. Remove RCS files from
5657 tconfig and xconfig. Add config files for sun386. Add
5658 a few odd files to OTHERS and HFILES.
5660 Mon Sep 10 21:20:24 1990 John Gilmore (gnu at cygint)
5662 * Makefile.dist: Pull solib.c to tconfig/sun?os4.
5663 Roll version number to 3.91.5. Make lint work in bindir.
5665 * README: Document cross-debugging and new file structure.
5667 * blockframe.c: Lint. Include "value.h" to declare read_register.
5668 (find_pc_partial_function): remove duplicate line.
5670 * command.h: Lint. Declare error_no_arg and dont_repeat.
5672 * tm-news.h: Remove inadvertently duplicated stuff.
5674 * mipsread.c: Remove cache_pc_function stuff, now done cleanly.
5675 Clean up usage of misc_function_type. Declare some CORE_ADDRs.
5677 * config.gdb: Allow `config.gdb host target' form. Clean
5678 up previous change that printed bogus messages when you just said
5681 * core.c: #include "command.h" for lint.
5684 * main.c: Remove some casts of enums. Lint.
5691 * printcmd.c (initialize_printcmd): Fix thinko in inspect cmd.
5693 * sparc-tdep.c (isannulled): Take instruction as parameter, don't
5694 read it from memory. This will allow us to save ptrace calls
5695 eventually. Changed caller single_step too.
5697 * sparc-xdep.c (fetch_inferior_registers): Avoid reading regs
5698 that we aren't going to use, saving many ptrace calls, especially
5699 when watchpointing or single stepping. Use some #define's for
5701 (store_inferior_registers): Ditto.
5702 (core_file_command): Use some #define's for constants.
5704 * tm-sparc.h: Add #define's for some register numbers, so we
5705 can eliminate the use of random constants in sparc-xdep.c.
5707 * stack.c (frame_command, print_frame_info, up_command,
5708 down_command) Remove frame_changed, since it
5709 causes a bug and doesn't seem to do anything useful. In some
5710 places it was used as a flag, in others as a stack level (?).
5712 * utils.c: Use MISSING_VPRINTF rather than HAVE_VPRINTF, so the
5713 default is to use the portable (vprintf) version rather than the
5715 * xm-news.h (MISSING_VPRINTF): Add.
5717 * valprint.c (val_print): Demangle fancy vtbl printouts. Lint.
5719 Sat Sep 8 00:24:12 1990 John Gilmore (gnu at cygint)
5721 * Remove stuff that forces -Bstatic linking of gdb, and warnings
5722 about linking debugged programs -Bstatic in the sun?os4 config
5723 files in tconfig and xconfig subdirectories.
5725 * main.c (main): Remove unreached exit(0) now that we exit
5728 * Create TODO file for online bug list. There are too many
5729 "little" bugs to keep track of on paper.
5731 * Change Projects file to refer to bug-gdb@cygnus.com
5732 rather than kingdon@ai.
5734 Fri Sep 7 23:35:15 1990 John Gilmore (gnu at cygint)
5736 * Makefile.dist (VERSION): 3.91.4 now.
5738 * symtab.c (init_misc_bunches): Rename from init_misc_functions.
5739 (condense_misc_bunches): Add sanity check that misc_count is
5740 the same as the number of symbols in the bunch.
5742 * coffread.c: rename init_misc_bunches. Pass an argument
5743 to condense_misc_bunches (a zero).
5745 * dbxread.c (partial_symbol_file_read): Call init_misc_bunches
5746 every time we are called; don't rely on our caller to do it.
5747 (add_file): Remove call to init_misc_bunches.
5749 * mipsread.c: Only warn, don't error, if unknown symbol types.
5750 This keeps an old gdb from falling on its face if it sees newly
5751 extended symbol info. Rename init_misc_bunches.
5753 Fri Sep 7 22:58:15 1990 John Gilmore (gnu at cygint)
5755 * Merge in changes from Per Bothner for DECstations and other
5756 MIPS stuff. The rest is Bothner speaking:
5758 The next message is a merger of Alessando Forin's mips port with
5759 mine. I've tried to use my good if biased judgment to get
5760 the best of both. It *does* need testing.
5762 Some of the changes are general, *not* mips-specific.
5765 Didn't believe in little-endian bit order.
5766 There are still inconsistencies about whether flags
5767 like BITS_BIG_ENDIAN are integer (#if ...) or
5768 boolean (#ifdef ...). I tried to paper over them.
5770 dbxread.c,coffread.c,mipsread.c,symtab.c,symtab.h:
5771 Moved some misc_function code that was common to
5772 {dbx,coff,mips}read.c to symtab.c.
5773 In the process, I think I cleaned things up a bit.
5774 At the same time, moved obsavestring and obconcat to symtab.c.
5777 Removed obsolete condense_addl_misc_bunches (use
5778 condense_misc_bunches(1) instead).
5781 Needed to include <sys/dir>, at least on DECstations.
5783 valops.c, mips-tdep.c, tm-mips.h:
5784 Added PUSH_ARGUMENTS macro to support funny argument-pushing
5785 conventions (when STACK_ALIGN is insufficient).
5786 Needed on mips, where doubles need 8-byte alignment,
5787 but ints only need 4.
5790 Removed cruft that was not being used.
5791 Merged in many fixes (most from Frank Yellin, fy@lucid.com).
5794 Print $ before register-names (I think that makes things a little
5796 Never print two instructions, even if one delays.
5797 Removed hex-disassemble set_cmd. (This is not mips-specific,
5798 so I think the argument is whether it is generally worthwhile or not.
5799 I'm inclined to think not, given how easy it is to
5800 convert between radixes in gdb.)
5803 This is basically Alessando's code.
5804 It doesn't use obstacks; I changed it to use obstacks
5805 in a few minor places where using malloc causes a
5806 memory leak. (Probably, more places could/should be changed.)
5807 I added record_misc_function where it was missing.
5808 In symbol_file_command and add_file_command, I tried
5809 to make the code consistent with more recent versions.
5810 Minor sylistic changes in parse_procedure.
5811 Make a .gdbinfo. psuedo-symbol point back to the real
5812 procedure symbol (using the isym field).
5815 This is basically from my port, but with a lot of details
5816 and a number of routines merged in from Alessando's version.
5817 I basically used my code "raw" backtrace (use heuristics
5818 from the actual code, rather than symbol table info) - though
5819 the idea is Alessandro's. I feel my code is a little cleaner
5820 here, particularly in being a little more flexible, such as being
5821 able to handle gcc-produced code (which it now can).
5822 It also doesn't do frame caching (which is not useful
5823 more recent gdb versions).
5824 I also used my code for push_/pop_dummy, more or less.
5825 I tried to incorporate AF's code for testing sigtramp
5826 while backtracing; I probably got it wrong.
5827 Added mips_print_register, which tries to scrunch as much
5828 information as possible on a screen...
5829 Removed the skip-prologue set_cmd. As with hex-disassemble (see
5830 under mips-pinsn.c), I don't see anything mips-specific here,
5831 and I don't see it being all that useful anyway.
5834 Added a $fp psuedo-reg distinct from $fp (nice for gcc).
5835 Use more register names (rather than hard-cases numbers).
5837 Thu Sep 6 18:33:15 1990 John Gilmore (gnu at cygint)
5839 * Hack up 3.90.11 changes:
5841 * Makefile.dist (depend): parameterize $(GCC).
5842 Add solib.c and solib.o.
5843 (readline): Fix vpath for both absolute or relative SRCDIR.
5845 * blockframe.c: Fix from Schaefer@asc.slb.com for shared libs.
5846 Also, let the part I didn't understand at least compile so
5847 I can test the rest. FIXME.
5849 * dbxread.c: Fix thinko using strcmp.
5850 (init_psymbol_list): declare static.
5851 (partial_symbol_file_open): Comment cleanups better, avoid
5852 cleaning up the string table since the caller will do that.
5853 Move the stat for mod time into symbol_file_command, temporarily.
5854 (There should be a mod time for each symbol file, eventually,
5855 to control its rereading. FIXME.)
5857 * infptrace.c (PT_WRITE_D): use same value as PT_WRITE_I for
5858 SunOS, which gives error for shared libs otherwise. (From
5859 Schaefer, probably FIXME needs work for portability.)
5861 * solib.c: Move #include "param.h" to work.
5862 Lowercase all the Uppercase Letters In the Messages.
5863 (find_solib): Clean up inferior_so_name for debug printouts.
5864 Allow no argument, to mean all shared libraries.
5866 * symmisc.c: include param.h to get CLEAR_SOLIB.
5868 Wed Sep 5 18:00:08 1990 John Gilmore (gnu at cygint)
5870 * Merge in Kingdon's changes from FSF: the diffs from 3.90.9
5871 to 3.90.11. ChangeLog entries below are from this.
5873 Wed Jun 13 09:17:39 1990 Jim Kingdon (kingdon at mole.ai.mit.edu)
5877 * Makefile.dist (HFILES): Add tm-sunos.h.
5879 Tue Jun 12 16:15:26 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5883 * Makefile.dist (gdb.tar.Z): Change linking of config so it works.
5885 Thu Jun 7 16:22:27 EDT 1990 Jay Fenlason (hack@ai.mit.edu)
5887 * sparc-opcode.h Added single-operand version of rett.
5889 Mon Jun 4 18:12:31 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5891 * m-sparc.h (REG_STRUCT_HAS_ADDR, STRUCT_ARG_SYM_GARBAGE):
5892 Put parens around gcc_p in expansion.
5894 Thu May 24 15:44:51 1990 Jim Kingdon (kingdon at mole.ai.mit.edu)
5896 * utils.c (lines_to_list): Return 10 if lines_per_page == 0.
5898 Wed May 23 16:36:04 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5900 * Changes for Sun shared libraries:
5901 blockframe.c (find_pc_partial_function): If a non-text symbol
5902 is found, set *address = pc - FUNCTION_START_OFFSET.
5903 breakpoint.c (insert_breakpoints) [DISABLE_UNSETTABLE_BREAK]:
5904 Disable breakpoints instead of giving an error.
5905 source.c (select_source_symtab): Initialize cs_pst.
5906 symmisc.c: Call CLEAR_SOLIB if defined.
5907 symtab.h: Make text{low,high} CORE_ADDR not int.
5908 (psymtab): New field addr.
5910 dbxread.c: Move DECLARE_FILE_HEADERS outside functions.
5911 (record_misc_function): Give correct type for N_DATA symbols.
5912 (condense_misc_bunches): do "misc_function_count = j" regardless
5914 Take code which is shared between symbol_file_command and
5915 add_file_command and put it into partial_symbol_file_{open,read}.
5916 Split add_file_command into add_file_command and add_file.
5917 Make psymtab_to_symtab read in the string table if the file
5919 Two new parameters to read_dbx_symtab and start_psymtab.
5920 tm-sunos.h: New file.
5922 Tue May 22 17:43:03 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5924 * infcmd.c: Change cont_command to continue_command and "cont"
5927 Mon May 21 14:41:41 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5929 * breakpoint.c (enable_breakpoint): Get value of watchpoint.
5931 * defs.h [sparc]: Use <alloca.h> regardless of __GNUC__.
5933 * values.c (USE_STRUCT_CONVENTION): Check for structures of
5934 size 1,2,4,8 rather than size < 8.
5936 * dbxread.c (dbx_lookup_type): Do f->length *= 2 as many times
5937 as necessary, not just once.
5939 * sparc-opcode.h: Add a bunch of new opcodes which Sun as supports.
5941 Thu May 17 15:04:09 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5943 * {t,x}m-sun386.h, sun386-xdep.c, {x,t}config/sun386
5945 * tm-news.h: Add CALL_DUMMY_*.
5947 * tm-68k.h: Remove duplicate comment at FRAME_FIND_SAVED_REGS.
5949 * config.gdb: In list_host, list_target, use ${i}, not $i.
5951 Tue May 15 21:27:12 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5953 * source.c (find_source_lines) [BROKEN_LARGE_ALLOCA]: Use xmalloc.
5955 * sparc-opcode.h: Change all store floating-point state register
5956 instructions to have the right match & lose fields.
5958 Sat May 5 12:39:18 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5960 * Makefile.dist: Move -I${srcdir} to GLOBAL_CFLAGS and pass
5962 config.gdb: If srcdir != ., create readline directory and
5963 copy a makefile into it.
5965 * wait.h, infrun.c: Change WRETCODE to WEXITSTATUS for
5966 consistency with POSIX.
5968 * breakpoint.c (bpstat_stop_status): Disable watchpoint
5969 when we exit its exp_valid_block.
5971 Tue Sep 4 11:46:46 1990 John Gilmore (gnu at cygint)
5973 * Makefile.dist: Bump version to 3.91.3.
5975 * Clean up handling of breakpoint commands (somewhat).
5976 Prompted by Tiemann bug report "cont 10" doesn't work any more.
5978 inferior.h: Add breakpoint_proceeded to inferior status struct
5979 and globals; save it and restore it.
5980 (clear_breakpoint_commands): Cleanup, remove old #define.
5982 infrun.c (clear_proceed_status): Set breakpoint_proceeded.
5983 (save_inferior_status, restore_inferior_status): handle it also.
5984 (proceed): Remove earlier code that set breakpoint_proceeded.
5985 It is now set only in clear_proceed_status.
5986 (clear_proceed_status): Cleanup, use bpstat_clear rather
5987 than clear_breakpoint_commands. No callers need the stop_bpstat
5988 between clear_proceed_status and proceed.
5990 infcmd.c: Add breakpoint_proceeded definition and comment.
5991 (cont_command, jump_command, signal_command): Move call to
5992 clear_proceed_status right next to call to proceed.
5994 breakpoint.c (bpstat_do_actions): Avoid clobbering our
5995 caller's argument while running down the chain of breakpoints.
5996 Use new variable "breakpoint_proceeded" to determine when
5997 a command that it executes moves the inferior past the
5999 (bpstat_clear): Handle NULL argument.
6000 (bpstat_clear_actions): Avoid useless call to
6001 breakpoint_auto_delete.
6002 (delete_breakpoint): Clean up bpstat's that are pointing to
6003 the deleted breakpoint from the stop_bpstat chain.
6004 (breakpoint_auto_delete): Simplify.
6006 * Clean up handling of EOF, error on stdin, etc. This was
6007 prompted by a network problem that caused gdb to go into an
6008 infinite loop filling up its malloc'd memory.
6010 main.c (return_to_top_level): Cleanup: call bpstat_clear_actions,
6011 not clear_breakpoints_commands, which is now gone.
6012 (main): If command_loop returns (e.g. from EOF on stdin), do
6013 a quit_command (looping back to command_loop if quit_command
6014 doesn't really quit).
6015 (command_loop): check result from command_line_input and
6016 exit if it returns NULL, rather than passing the NULL to
6018 (gdb_readline): Free malloc'd result space before returning
6021 * utils.c (query): Handle C-d to mean "yes", just as if the
6022 input was not a terminal. Also avoid infinite loop if EOF
6023 occurs in mid-input-line before newline. This allows
6024 query to be used at EOF on stdin with reasonable results.
6026 * infrun.c (proceed): Set breakpoint_proceeded.
6028 * values.c (value_as_long): Avoid infinite recursion for enums.
6029 (_initialize_values): Fix typo in help msg (kingdon).
6031 * Makefile.dist (RL_LIB): Use RL_LIB_DEP for dependencies,
6032 RL_LIB for linking. This allows -lreadline for linking
6033 and nothing for dependencies, once readline is a real library.
6035 * config.gdb: Jim Kingdon: give useful error message if the
6036 host or target type is not recognized.
6038 * defs.h (alloca): SPARC <alloca.h> does not declare alloca,
6039 it just defines it. Dumb, but deal with it.
6041 * Jim Kingdon suggests:
6042 in xconfig/sun3os4, CFLAGS should be XM_CFLAGS.
6044 Wed Aug 29 18:03:27 1990 John Gilmore (gnu at cygint)
6046 * Makefile.dist (VERSION): Bump version # to 3.91.2.
6048 * Clean up Bothner's changes.
6050 * blockframe.c (clear_pc_function_cache): New function.
6051 * blockframe.c: remake cache_pc_function_* static.
6052 * dbxread.c (symbol_file_command): remove references to
6053 cache_pc_function_* variables.
6054 * dbxread.c (read_struct_type): Use VOFFSET_STATIC.
6055 * printcmd.c: Avoid kludging a global variable (addressprint)
6056 to avoid printing the address of a string twice. Instead,
6057 pass the format letter 's' down low enough that it can be seen
6058 to avoid this problem.
6059 (print_formatted): Pass format arg to value_print.
6060 (restore_addressprint): Remove function.
6061 (do_examine): Avoid hacking addressprint, cleanups and such.
6062 (print_frame_args): Add a comment to a Bothner change.
6063 * symtab.h: define VOFFSET_STATIC and use it instead of "-1".
6064 * symmisc.c (free_all_symtabs): Call clear_pc_function_cache
6065 to wipe out the values cached in blockframe.c.
6066 * symtab.c (find_method): Add comment saying how big you must
6067 allocate to be "big enough". Per being terse again.
6068 * valprint.c (val_print): Handle format letter "s" to print
6069 strings without addresses. Add comment to vtbl printing code
6070 which casts with wild abandon. Rearrange reference-printing
6072 @0xaddr: value (print w/addressprint)
6073 value (print w/~addressprint)
6074 @0xaddr (parameter lists w/addressprint)
6075 or nothing (parameter lists w/o addressprint)
6077 Tue Aug 28 10:47:18 1990 John Gilmore (gnu at cygint)
6079 * Merge more changes from Per Bothner:
6081 Gdb's handling of TYPE_CODE_REF was so counter-C++ (and otherwise
6082 annoying) that I tried to improve it. Here are my suggestions.
6084 These patches all attempt to handle TYPE_CODE_REF (as in C++) better.
6087 Do automatic de-reference when taking the address of a reference.
6089 Don't deref_ref when printing parameter lists.
6091 More attempts at treating refernences properly.
6093 In val_print, if deref_ref==0, don't print dangling " = ".
6095 Add COERCE_REF macro, which de-references an REF.
6097 * Merge changes from Per Bothner:
6099 * Fixed (Sony news)-specific configuration problems.
6100 * Fixed other problems with using vanilla pcc and libc (enum problems;
6101 assumption that vsprintf exists).
6102 * Some major speed-ups (finc_pc_partial_function now caches a match;
6103 parsing avoids duplicate symbol_lookup calls).
6104 * Changed handling of baseclasses (no longer use baseclasses field
6105 of struct type, use the first n_baseclasses fields instead).
6106 * Various minor changes/fixes, most C++-related.
6109 Cache the most previous match from find_pc_partial_function.
6110 (Save both low and high ends of matching function's pc range.)
6111 This speeds up the loop of infrun.c:wait_for_inferior quite
6112 a bit, and makes step/next commands much zippier.
6114 Added an enum->int cast (otherwise, some compilers barf).
6116 No longer set baseclass offset to 0, since multiple
6117 inheritance now mostly works.
6118 Added a number of casts, to shut up compiler warnings
6119 (after stabs where made enums, not ints).
6120 When discarding a symbol table (in symbol_file_command),
6121 must clear the cache introduced in blockframe.c.
6122 Don't convert $vtbl_ptr_type to vtbl any more.
6123 Get rid of TYPE_BASECLASEES and baseclass_vec (see also symtab.h).
6124 Mask off sign bit emitted by g++ for virtual table offset.
6125 Set voffset to -1 (not 1) for static member functions.
6127 Changed parsing/lexing of names to avoid doing symbol lookup twice
6128 (once when lexing to determine symbol class, once for real).
6129 Now only call symbol_lookup once. Fields of 'this' win especially big.
6131 Subpress printing addr twice in the case of 'x/s addr'.
6133 lookup_basetype_type is no longer used.
6134 Add find_methods as recursive helper function to decode_line_1.
6135 This allows multiple inheritance to work.
6136 Also, once one or more matches has been found, do not look in
6137 base-classes. (Baseclass methods would be overridden, anyway.)
6139 Removed baseclasses array in struct type.
6140 Instead of using baseclasses[i], use fields[i-1].
6141 Added virtual_field_bits[i] to indicate if the i'th baseclass is virtual.
6142 Changed sign convention of voffset (previous was inconsistent).
6144 Some macros (CALL_DUMMY and relatives) were missing. Put them back.
6146 Used to assume existence of vsprintf. Re-written to not need it
6147 if HAVE_VPRINTF is undefined.
6149 typecmp was too pessimistic. Made it less so.
6151 Don't print space after address.
6152 If vtable points to a misc symbol (with 0 offset), print it,
6153 since that indicates the actual class of the object.
6154 Changed ype_print_derivation_info to use new inheritance
6155 scheme (without baseclasses vector).
6157 In value_primitive_field, fixed some bugs left over from previous set of fixes.
6158 Also, changes needed because TYPE_BASECLASSES were removed.
6160 REGISTER_U_ADDR didn't work for PC. Rewrote to use an array.
6162 Tue Aug 21 20:08:54 1990 John Gilmore (gnu at cygint)
6165 If there is no path set, and the symbols don't indicate what directory
6166 a file was compiled in, look in the current directory. But either
6167 a path or a known compilation directory will prevent this.
6170 Three independent bug fixes:
6171 * Remove the #if 0 block that breaks some stuff.
6172 * SunOS 4.1 fixed the promoted-parameter-wrong-addr bug in Sun C;
6173 adapt gdb to either SunOS 4.0.* or 4.1.
6174 * MAX_OF_TYPE and MIN_OF_TYPE thinko. By tedg@sun, I think.
6177 Instantiate the class T when looking for methods in it. (Tiemann@sun)
6180 (type_print) Demangle the name being printed.
6181 (type_print_base) Handle botched demangling without coredump (tiemann).
6184 (check_stub_method): Document routine.
6185 (tiemann) fix bug for no-arg functions
6186 Avoid clobbering beyond end of malloc'd storage.
6187 Terminate the argument list properly.
6189 Sat Aug 18 01:29:59 1990 Per Bothner (bothner@cs.wisc.edu)
6191 * Changes merged by John Gilmore:
6194 In breakpoint_1, use new print_address_symbolic instead
6195 of find_pc_partial_function. (This forces use of assembler-level
6196 addresses, and avoids misleading non-mangled source-level names.)
6198 Generalize ansi argument such that -1 means skip arglist totally.
6199 Removed global variable print_ansi_qualifiers (which made
6200 code non-reentrant), in favor of extra explicit arguments
6201 to internal routines.
6203 Add new helper function print_address_symbolic.
6204 Use find_pc_misc_function instead of find_pc_partial_function
6205 (since we want assembler-level symbols here).
6207 Print unknown function as just "f (...)", not "f (...) (...)".
6208 Use new fputs_demangled explicitly.
6210 Fixed a typing violation (problem: value.h cannot be imported
6211 without renaming many variable in this file).
6212 lookup_symbol: If no matching misc_func, look for a C++-mangled name.
6213 decode_line_1: Moved forward some never-reached code.
6214 Made decode_line_2 skip function prologues correctly.
6216 fputs_filtered should not demangle by default.
6217 Add new fputs_demangled to demangle on demand..
6219 Change value_struct_elt to use value_primitive_field (using recursive
6220 utility function search_struct_field). This allows foo.bar to work
6221 for multiple inheritance (so far only for data fields).
6222 Change check_field in the same way (recursive helper function
6223 to support multiple inheritance).
6224 (Note: there are more of these problems that I haven't fixed.
6225 Any code that says TYPE_BASECLASS (t, 1) is probably wrong.)
6226 value_of_this: 'this' symbol name is now just "this", note "$this".
6228 Don't print static members.
6229 Avoid printing "members of <type>" if there are none.
6230 Simplified type_print_derivation_info by merging duplicate code.
6231 Remove useless blank lines in type_print_base (ptype command).
6233 Added declaration of new routine value_primitive_field.
6235 Added value_primitive_field which is generalized version of
6236 value_field that can handle multiple inheritance (non-zero offsets etc).
6237 Re-implemented value_field to call value_primitive_field.
6239 Fri Aug 17 23:33:44 1990 John Gilmore (gnu at cygint)
6241 * infcmd.c -- insert else to avoid 'delete env' coredump when you
6242 delete the whole environment. Karl Berry reported the bug.
6243 * source.c - fix openp to avoid //'s in filenames, which
6244 trigger an Emacs bug causing it to not be able to find files
6245 when running gdb in a window.
6246 * dbxread.c - zap the #if 0 that botches the add-file code.
6247 It seems to work a lot better without all the code commented out.
6249 Fri Jul 20 16:58:46 1990 John Gilmore (gnu at cygnus.com)
6251 * Merge Tiemann's and Ted Goldstein's changes, detailed below,
6254 Tue Jul 17 19:34:33 1990 Ted Goldstein (tedg at golem)
6256 * Makefile - added a ${CFLAGS} to a couple of entries,
6257 added remote-sa.sparc.c
6258 * added remote.sa-sparc.c, a modification of remote.c
6259 which conducts a dialog directly with the SparcStation prom.
6260 * breakpoint.c, infrun.c, sparcdep.c added
6261 remote_insert_breakpoint(), and remote_remove_breakpoint()
6262 to breakpoint.c instead of directly writing breakpoint instructions.
6263 * sparcdep.c on remote_debugging,there is no need
6264 to remove signle step breakpoint instructions.
6265 * main.c added "-epoch" flag and "int epoch_interface" to main.c
6267 * printcmd.c - epoch interface sends lisp expressions to open up
6268 epoch windows on inspection.
6269 * valprint.c - added arrayprint, and addressprint and made adding
6270 format controls easier
6271 * wait.h added a couple of undef's because we were getting
6272 complaints about WSTOPSIG and WTERMSIG begin redefined.
6275 Wed Jul 4 05:27:51 1990 Michael Tiemann (tiemann at masham)
6277 * symtab.c (decode_line_1): Add support for handling method stubs
6278 in the type information.
6280 Tue Jul 3 09:39:18 1990 Michael Tiemann (tiemann at masham)
6282 * values.c (baseclass_addr): Run loop from INDEX+1 to
6283 N_BASECLASSES; otherwise, we can still get into a loop.
6284 @@ This should be restructured to use a cleaner search strategy.
6286 Sun Jul 1 12:28:51 1990 Michael Tiemann (tiemann at masham)
6288 * dbxread.c (define_symbol,read_type): Grok GNU C++'s new
6289 abbreviation "Tt" for tags which have the same name as their
6292 Fri Jun 29 01:03:46 1990 Michael Tiemann (tiemann at masham)
6294 * symtab.c (list_symbols): add ability to set breakpoints on all
6295 the functions which match a particular regular expression.
6297 Tue Jun 26 04:26:29 1990 Michael Tiemann (tiemann at masham)
6299 * cplus-dem.c (cplus_demangle): New parameter ANSI says whether we
6300 should print ANSI qualifiers (such as `const' and `volatile').
6301 All callers changed to call with ANSI == 1, except from
6302 `check_method_stub', which uses old-style syntax.
6304 * symseg.h (struct fn_field): Remove unneccessary `args' field.
6305 * symtab.h (TYPE_FN_FIELD_ARGS): Redefined.
6307 * values.c (check_stub_method): New function.
6309 * cplus-dem.c (do_type): Handle "long long" (encoded as 'x').
6311 * dbxread.c (read_type): Handle new GNU C++ method type stubs.
6312 * valprint (type_print_base): Ditto.
6314 * symtab.c (gdb_mangle_typename): New function.
6316 Tue Jun 5 00:18:43 1990 Michael Tiemann (tiemann at gzilla)
6318 * breakpoint.c (catch_command): New function. Provides a
6319 mechanism to set breakpoints based on catch clauses.
6320 (disable_catch): Similar, but disables breakpoints on catch
6322 (delete_catch): Similar, but deleted breakpoints on catch clauses.
6324 Sun Jun 3 22:54:08 1990 Michael Tiemann (tiemann at gzilla)
6326 * blockframe.c (blockvector_for_pc): New function.
6327 * blockframe.c (block_for_pc): Changed to call
6328 `blockvector_for_pc' and get the block itself.
6330 * stack.c (catch_info): New function. Prints info about
6331 exceptions which can be caught in the current frame.
6332 * stack.c (print_frame_label_vars): New function. Similar to
6333 `print_frame_local_vars'.
6334 * stack.c (print_block_frame_labels): Prints out labels that are
6335 defined in this frame. These labels are exceptions that can be
6338 * dbxread.c: Updated to handle N_CATCH symtab types.
6340 Thu May 3 22:10:00 1990 Michael Tiemann (tiemann at teacake)
6342 * valprint.c (everywhere): TYPE_NAME (TYPE) no longer comes in the
6343 form "struct ..." for GNU C++. Don't flush any part of TYPE_NAME
6344 when printing the type.
6346 Wed May 2 22:43:04 1990 Michael Tiemann (tiemann at teacake)
6348 * valprint.c (val_print): Use `baseclass_addr' to access the
6349 baseclasses pointed to via the derived class object at VALADDR.
6351 * values.c (baseclass_addr): New function. Casts derived pointers
6352 to baseclass pointers taking virtual baseclasses and multiple
6353 inheritance into account.
6355 Sat May 5 12:39:18 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
6359 Fri May 4 12:12:55 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
6361 * breakpoint.c (watch_command, bpstat_stop_status): Deal with
6362 exp_valid_block field correctly.
6364 * infrun.c (wait_for_inferior): When checking "don't even think
6365 about breakpoints" if stop_signal == SIGTRAP && trap_expected,
6366 also check step_resume_breakpoint.
6367 Insert breakpoints and continue (not step) if
6368 step_resume_break_address != NULL, even if another_trap.
6369 If trap_expected and we enter sigtramp, then set up a
6371 If trap_expected is set when we hit the step_resume_break,
6373 When calling resume and trap_expected says tell resume to step
6374 (2 places), also check step_resume_break_address.
6376 * infrun.c (wait_for_inferior): Don't set
6377 prev_{pc,sp,func_{start,name}} before calling wait ().
6378 Do set them after exiting loop.
6379 Move their declarations outside functions.
6380 (start_inferior): Initialize them.
6382 Thu May 3 00:15:11 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
6384 * infrun.c (wait_for_inferior, after check for trap_expected > 1):
6385 Restore old code which distinguishes between trap_expected and
6386 running_in_shell, just make the latter take any non-TRAP signal,
6389 * values.c (allocate_value): Zero VALUE_OPTIMIZED_OUT flag.
6391 * Makefile.dist (pinsn.o): Use PINSN_CC to compile.
6392 xconfig/3b1 (CC,PINSN_CC): Define.
6394 * xconfig/altos, altos-dep.c: Rename altos-dep.c to altos-xdep.c.
6398 * breakpoint.c (bpstat_stop_status),
6399 infrun.c (wait_for_inferior) [SHIFT_INST_REGS]: New code.
6401 * param.h, tm-88k.h: Define ADDR_BITS_*.
6402 infcmd.c (jump_command, read_pc), infrun.c (wait_for_inferior),
6403 printcmd.c (do_one_display): Use them.
