12 * xm-delta88.h: Use it.
13 * tm-*.h: Remove FRAME_CHAIN_COMBINE macros, since all are
15 * coffread.c: Remove tdesc stuff.
16 * tconfig/delta88, tconfig/m88k: Remove tdesc stuff.
17 * xconfig/m88k: Rename tm-88k.h to tm-m88k.h.
19 Mon Nov 18 13:51:37 1991 Per Bothner (bothner at cygnus.com)
21 * source.c (open_source_file): If openp fails, try again
22 using just the base (non-directory) part of the filename.
23 This solves various annoying problems, such as when the
24 source was compiled with an absolute pathname - and the
25 source files have moved. Or if the source was compiled
26 using a relative pathname, it can be more convenient
27 to just specific the source directory to the dir command.
29 Mon Nov 18 00:04:41 1991 Fred Fish (fnf at cygnus.com)
31 * cplus-dem.c (munge_function_name): Add missing third arg to
32 instance of call to do_type().

40 * symtab.h (struct type): Moved C++-specific fields into new type
41 `struct cplus_struct_type'. Now takes 10% less memory. Many

44 TYPE_CPLUS_SPECIFIC unless TYPE is TYPE_CODE_STRUCT.
45 * buildsym.c (read_type): Allocate TYPE_CPLUS_SPECIFIC for
47 (read_struct_type): Ditto. Also, add comments about how we can
48 deduce TYPE_VPTR_FIELDNO from inheritance info and fieldname info.
49 * coffread.c (decode_base_type): Allocate TYPE_CPLUS_SPECIFIC for
51 (read_struct_type): Ditto.
52 * dwarfread.c (struct_type): Ditto.

66 compiler from making gdb bomb out. Thanks to Ed Santiago!
68 Thu Nov 14 19:27:30 1991 Fred Fish (fnf at cygnus.com)
70 * symfile.c: Add function compact_misc_function_vector() to
71 remove duplicate misc function vector entries. See comments
72 in source for why this is necessary/desirable.
74 * dwarfread.c: Add misc function type parameter to internal
75 record_misc_function(). Remove calls to init_misc_bunches()
76 and condense_misc_bunches(), these are now done in elfread.c.
78 * elfread.c: Add support for reading bfd canonical symbol tables
79 and generating misc function vector entries for global and
80 absolute symbols. Do calls to init_misc_bunches() and
81 condense_misc_bunches() where they will enclose all calls to
82 record_misc_function(), including those in dwarfread.c.
84 Thu Nov 14 17:02:11 1991 Roland H. Pesch (pesch at cygnus.com)
86 * doc/Makefile.in: new targets gdb.me, gdb.ms, gdb.mm

110 (examine_prologue, frame_find_saved_regs, skip_prologue): borrow
111 from i960-tdep.c and adapt to the function prologues on the 88k.
112 (read_next_frame_reg): Borrow from mips-tdep.c.
113 FIXME: frame_locals_address should go away.
115 * tm-delta88.h: Dump all the tdesc stuff.
116 Macros for all frame-related stuff call fns of same name.
117 Remove duplicated definitions. FP_REGNUM becomes same as
120 * xm-88k.h: Eliminate lots of library dependencies, now handled
121 in libiberty. Eliminate KDB nonsupport.
123 * doc/gdbint.texinfo: Add rudiments on frames. FIXME, add more.
126 * stack.c (frame_info): Mark frameless functions.
127 Print locals address (FIXME, remove if same).

142 * symtab.c (decode_line_1): Remove spurious call to operator_chars.
144 Allow setting breakpoints on C++ destructors.
145 * valops.c (destructor_name_p): Don't check TYPE_HAS_DESTRUCTOR,
146 since it lies. Rely on callers to catch missing destructors.
147 * symtab.c (decode_line_1): For example (see above), here.
148 * buildsym.c, symtab.h: Remove TYPE_FLAGS_HAS{CON,DE}STRUCTOR
149 flags since they are no longer used.
151 Fixes to support C++ methods with functional parameters.
152 * c-exp.y (func_mod rule): Allow (and ignore) list of parameter
153 types in a function type.
154 * eval.c (parse_and_eval_type), value.h: New function,
155 parse_and_eval_type, is based on old code from check_stub_method.
156 But don't actually evaluate the cast, since that calls
157 value_cast(), whcih may fail. Just extract the type
158 from the parsed expression.
159 * values.c (check_stub_method): While looping through the
160 arguments, adjust depth *after* parameter has been handled.
161 Replace call and setup of parse_and_eval with new function
164 Tue Nov 12 09:40:07 1991 Fred Fish (fnf at cygnus.com)
166 * utils.c, rem-multi.shar: Remove fixed arg count version of

171 m88k-xdep.c, main.c, printcmd.c, pyr-xdep.c, source.c,
172 sun386-xdep.c, symm-xdep.c, umax-xdep.c, values.c, xcoffread.c:
173 Change all instances of use of fixed args concat() to variable
174 args concat() now located in libiberty.
176 Tue Nov 12 07:23:46 1991 John Gilmore (gnu at cygnus.com)

183 xm-rs6000.h, rs6k-opcode.def, rs6k-opcode.h: New files.
184 * xcoffexec.c: New file for handling AIX shared libraries.
186 Mon Nov 11 19:14:31 1991 Fred Fish (fnf at cygnus.com)
188 * core.c: Minor rewording of message to user containing name of
189 (and possibly arguments to) the program that generated a core
192 * elfread.c: Remove the register_addr() stub now that it is no
195 * procfs.c: Move misplaced #endif for ATTACH_DETACH. Add new
196 fetch_core_registers() function for core file support.

200 * dwarfread.c (dwarf_psymtab_to_symtab): Remove leftover call
201 to do_cleanups() which resulted from a previous change.
203 * elfread.c: Re-enable compilation of register_addr() stub
204 whenever it is not supplied by coredep.c
206 Sat Nov 9 00:40:32 1991 John Gilmore (gnu at cygnus.com)
208 Add tracking of object files (that contain symbols) to gdb.
209 This includes a "struct objfile" that owns symtabs and psymtabs
210 that were read in from that binary file.
212 * symfile.h: Add struct objfile. Add pointer to the objfile
213 into the struct sym_fns.
214 Replace global `symfile' and `symfile_mtime' with
215 `symfile_objfile'. Add global object_files chain.
217 * symfile.c: Move param.h above symtab.h.
218 (sort_misc_function_vector): Add.
219 (syms_from_objfile): Was syms_from_bfd.
220 (symfile_open): Now returns objfile.
221 (allocate_objfile): New.
222 (free_objfile): New, replacing free_all_.*symtabs.
223 (symfile_init): Takes objfile arg, puts it in sym_fns result.

229 * dbxread.c: Make more errors into complaints.
230 (push_subfile, pop_subfile): Move to buildsym.c.
231 (dbx_symfile_read, dbx_symfile_init, fill_symbuf, read_dbx_symtab,
232 start_psymtab, psymtab_to_symtab_1, read_ofile_symtab,
233 dbx_psymtab_to_symtab, ): Use bfd ops, don't use file descriptor.
234 Pass objfile. Change callers.
235 (fill_symbuf, SWAP_SYMBOL): Take bfd as arg.
236 (read_dbx_symtab): Just wipe out new symbols, not all, on error.
237 (end_psymtab): Blow away psymtab if empty.

243 (dbx_lookup_type): Handle null typevector.
244 (dbx_alloc_type): Check file number, not sym number, for -1.
245 (find_symbol_in_list): Add for xcoffread.
246 (start_symtab): Default typevector is empty. Keep reusing same
248 (end_symtab): Take objfile argument and pass it to
249 allocate_symtab. Don't make a symtab if no blocks or symbols.
250 Handle empty typevector.
251 (push_context): New function for context stack nesting.
252 (read_type): Mark FIXME where we need to reintroduce type smashing.
254 * buildsym.h (pop_context): Macro, paired with push_context.
255 (subfile_stack): Move here from dbxread.c.
257 * coffread.c (end_symtab, read_coff_symtab): Take and use objfile arg.
258 (read_coff_symtab): Cleanup by freeing objfile, not all symtabs.

263 * dwarfread.c (scan_compilation_units, start_psymtab,
264 process_dies, end_symtab, dwarf_build_psymtabs,
265 read_lexical_block_scope, read_func_scope, read_file_scope): Take
266 and use objfile argument.
267 (psymtab_to_symtab_1, read_ofile_symtab): Don't take or use file
268 descriptor. Use BFD internal functions instead.
269 (end_symtab): Call global allocate_symtab.
271 * elfread.c, target.c: Minor changes to accommodate objfiles.
272 * symtab.h: partial_symbol_table has no symfile_name member now.

274 (struct symtab): Add objfile * and objfile_chain * of symtabs.
275 (struct partial_symtab): Add objfile * and objfile_chain * of
276 psymtabs. Remove symfile_name.

280 listing if 2nd argument given. Print objfile info.
281 (printpsyms_command): Rename from print_partial_symtabs. Ditto all.
282 (printobjfiles_command): New; prints objfiles lists, and checks

285 * symfile.h, symfile.c, symtab.h: Lint
287 Fri Nov 8 23:38:48 1991 John Gilmore (gnu at cygnus.com)
289 * command.c: Include param.h.
290 * defs.h (warning_setup, warning): Declare.
291 * expprint.c (print_subexp, UNOP_MEMVAL case): Lint.
292 * inflow.c (new_tty): Use USE_O_NOCTTY #define.
293 * language.c, printcmd.c (print_scalar_formatted), signame.c,
296 Thu Nov 7 18:26:15 1991 Steve Chamberlain (sac at rtl.cygnus.com)
298 * Makefile.in: link with libiberty after libreadline, since
299 readline might want something in libiberty.
300 * m88k-xdep.c: Fixed the register offsets in the ptrace_user
301 struct for BCS 88k machines.
302 * xm-m88k.h: don't define USIZE if already defined.
303 * configure.in: Added delta88 target.
305 Thu Nov 7 04:51:19 1991 John Gilmore (gnu at cygnus.com)
307 * am29k-pinsn.c, am29k-opcode.h: Fix decoding of mtacc, dmac, fmac.
309 * tm-*.h: Remove READ_DBX_FORMAT, COFF_FORMAT, and
310 READ_MIPS_FORMAT, which have been unused since BFD. Still
311 remaining is COFF_NO_LONG_FILE_NAMES.
312 * tm-sun3.h, tm-altos.h: Remove detritus accidentally left from
313 function calling code moved to m68k-tdep.c.
315 Wed Nov 6 17:21:59 1991 John Gilmore (gnu at cygnus.com)
317 * coffread.c: Eliminate c_nsyms in favor of c_naux.
318 Complain if no auxents on .bf and .ef FCN symbols, and assume
319 lots of line numbers.
320 (init_linenos, enter_linenos): Use a sentinel at the end of the
321 read-in linenos, to make for a fast, safe loop-end test.
323 Wed Nov 6 02:54:08 1991 Steve Chamberlain (sac at cygnus.com)
325 * coffread.c (read_coff_symtab): coffread used to rely on the
326 x_sym.x_misc.x_lnsz.x_lnno field giving the # of linnos in a
327 function. Two of the formats I'm using (29k and 88k) don't seem to
328 set it. Ths patch to fcn_last_line and (enter_linenos) is an
329 attempt to use the actual size of the linno table in the file to set
330 the number of linenos to process.
332 Tue Nov 5 22:47:46 1991 Steve Chamberlain (sac at cygnus.com)
334 * Makefile.in: put a - infront of the mv y.tab.c c-exp.tab.c and
335 mv y.tab.c m2-exp.tab.c, so that if bison is used, and the files
336 are created in place, so the mv fails, then the make continues.
338 Tue Nov 5 16:47:47 1991 Per Bothner (bothner at cygnus.com)
340 Add C++ as a separate language.
341 * defs.h (enum language): Add language_cplus.
342 * dwarfread.c (end_symtab): Support language_cplus.
343 * c-exp.y: Add new struct language_defn cplus_language_defn.
344 Don't set c to be the default language (see main.c).
345 * c-exp.y (yylex): Only look for field of this if
346 language is C++. (First difference from C!)
347 * language.c: Add case branches for C++ (currently, all
348 the same as C). Also, add c++ to "usage" note for "set lang".
349 * valprint.c (typedef_print). Add case branches for C++.
350 * main.c (main): New way to set initial language: Look at
351 file extension of psymtab containing main(). (Same as we
352 do for symtabs, but avoid loading the symtab yet.)
353 * symtab.c: New routine find_main_psymtab(), used by main()
354 to set initial language.
355 * symfile.c (allocate_symtab): Move code for mapping file
356 extensions-> languages to new deduce_language_from_filename().
358 Fix a C++ problem when looking for methods in super-classes.
359 There was confusion between base and derived types.
360 * valops.c (value_fn_field): Change function interface.
361 * values.c: Use new value_fn_field interface.
363 Mon Nov 4 10:49:33 1991 Per Bothner (bothner at cygnus.com)
365 * infrun.c: Fixed typo in comment.
366 * utils.c: All the v*fprintf emulation is now in libiberty,
367 so we can get rid of some junk.
368 * xm-sun3os4.h, xm-sun4os4.h, xconfig/decstation, xconfig/i386sco,
369 xconfig/sun3os4, xconfig/sun4os4: Don`t need HAVE_STRSTR any more.
370 * m68k-pinsn.c (print_insn_arg): Support BB/BW/BL
371 type operands, as used by branch instructions.
372 * gmalloc.c: Fix prototype of memcpy.
373 * elfread.c: Comment out register_addr, since it conflicts
374 with the one in coredep.c.
375 * buildsym.h: Remove extern declarations of two functions
376 that are really static in buildsym.c.
377 * tm-mips.h: Add symbolic names for more registers.
378 * mips-xdep.c (store_inferior_registers): Use new register names.
379 * xm-mips.h: Simplify REGISTER_U_ADDR, since it is now
380 only used for core files, not ptrace. Therefore,
381 the KERNEL_U_ADDR hack is no longer needed.
382 The mapping to ptrace number is now in in mips-xdep.c.
383 * mips-xdep.c: Define REGISTER_PTRACE_ADDR (using the
384 mapping from the old REGISTER_U_ADDR), and use it
385 in {fetch,store}_inferior_registers.
386 * mipsread.c: Rename #include ecoff.h to new name coff-mips.h.
387 * mips-tdep.c (mips_push_dummy_frame, mips_pop_frame):
388 Save/restore FP regs correctly (?).
389 * dbxread.c: Remove duplicate define_symbol and type_synonym_name
390 (these had been previously moved to buildsym.c).
391 Hence, define_symbol becomes extern instead of static.
392 * buildsym.c (read_struct_type): Comment out bogus handling
393 of C++ operator methods. Minor hacking of reading of class
394 contexts. Make define_symbol non-static, so dbxread.c can call it.
396 Fri Nov 1 11:05:47 1991 John Gilmore (gnu at cygnus.com)
398 * mipsread.c (read_mips_symtab, read_the_mips_symtab): Use real
399 filename with error messages.
400 * stack.c (frame_select_command): Rename to select_frame_command
401 to avoid "fr" and "fra" having nonunique completions.
402 * symfile.c (sort_symtab_syms): Ignore sort of zero symtab *.
403 (symfile_init): Print file format name when unable to handle it.
404 (free_named_symtabs): Use BLOCKVECTOR rather than obsolete BLOCKLIST.
405 * symmisc.c (free_symtab): Only free linetable if nonzero.
406 * symtab.h: Remove obsolete BLOCKLIST macros.
408 Thu Oct 31 18:12:43 1991 Stu Grossman (grossman at cygnus.com)
410 * infrun.c (wait_for_inferior): another stepi/nexti fix. Ensure
411 that stop_step is 1 at bottom of main loop. I don't know why this
412 needs to be done, but it helps me sleep better at night.
414 Sun Oct 27 18:18:39 1991 Stu Grossman (grossman at cygnus.com)
416 * main.c (initialize_history): Read history after reading all
419 Sun Oct 27 14:09:25 1991 John Gilmore (gnu at cygnus.com)
421 * buildsym.c: Break out initial malloc sizes.
422 (record_line): Record directly in a subfile. Alloc on demand.
423 (compare_line_numbers): Add from xcoffread.c.
424 (end_symtab): New params say whether to sort pendings and
425 linetable. Patch block stabs if defined. Shrink linetable before
426 allocating the symtab.
427 * buildsym.h: Delete line_vector* and prev_line_number. Add
428 global_stabs and file_stabs for xcoffread.
429 * dbxread.c (start_subfile): Move to buildsym. Change above calls.
430 * symtab.h: LINETABLE(symtab) can now be null. Zap LINELIST.
431 * symmisc.c, symtab.c: Cope with null LINETABLEs.
433 * blockframe.c: Pass fromleaf to INIT_EXTRA_FRAME_INFO.
434 * tm-29k.h, tm-88k.h, tm-i960.h, tm-irix3.h, tm-mips.h, tm-pyr.h,
435 tm-sparc.h: Accept fromleaf parameter.
436 * c-exp.y (yyerror): Pass error message if given.
437 * configure.in: Add rs6000 host and target.
438 * inflow.c (new_tty): O_NOCTTY kludge for RS/6000.
439 * symfile.h (entry_point): Add.
441 Sat Oct 26 00:16:32 1991 John Gilmore (gnu at cygus.com)
443 * buildsym.c: New file. Breaks out symbol-table-building routines
444 from dbxread.c, so they can be shared with xcoffread.c.
445 * buildsym.h: New file. Declarations for buildsym.c users.
446 * dbxread.c: Remove large chunks into buildsym.c.
447 * Makefile.in: Add buildsym.c and buildsym.h.
449 * symfile.c (syms_from_bfd): New routine.
450 (add_symbol_file): Call it to do the real work.
451 (syms_from_bfd): Initialize entry_point before calling symfile_init.
452 * symtab.h, symfile.c, coffread.c, mipsread.c, dwarfread.c:
453 Avoid declaring or setting entry_point (symfile.h & symfile.c cope).
455 Fri Oct 25 10:58:16 1991 Mark Eichin (eichin at cygnus.com)
457 * cplus-dem.c (cplus-demangle): added support for templates, static
458 data, and the new (correct) mangling for destructors.
460 * dwarfread.c: (dwarfwarn): created a varargs version of
461 dwarfwarn, for non __STDC__ compilers.
463 * c-exp.y: (yylex): added match for "template" token.
464 (typebase): added TEMPLATE name '<' type '>' clause, for explicit
465 specification of template types.
467 * symtab.c: (lookup_template_type): new function for finding
468 templates in symbol table.
469 (type_name_no_tag): changed to explicitly check for s/u/e at the
470 beginning of the symbol - if it is a template, none of these will
471 be there (but the name will still contain spaces.)
473 Fri Oct 25 18:59:32 1991 Per Bothner (bothner at cygnus.com)
475 Various fixes to improve g++ debugging.
476 * symtab.h: Add is_const and is_volatile flags for each method.
477 These are bit fields - take their space from voffset,
478 which shrinks to 30 bits. Since voffset is now a bitfield,
479 make it unsigned for portability. This changes its interpretation
480 slightly: Static methods now have voffset 1 instead of -1,
481 and virtual offsets start at 2, not 1.
482 * symtab.c: Renamed gdb_mangle_typename to gdb_mangle_name,
483 since it now returns an entire magled method name, not just
484 the type part. This avoids some duplication.
485 It also allows us to correctly mangle const and volatile
486 methods (using the new is_const and is_volatile bit fields
488 * valprint.c (type_print_base), values.c (check_stub_method):
489 Simplify by using new gdb_mangle_name.
490 * values.c (value_headof): Fix to correctly handle single
491 inheritance (actually two fixes, either of which suffices).
492 * dbxread.c (read_struct_type): Handle const and volatile
494 * dbxread.c (read_struct_type): Yet one more place where
495 we must handle '\\' continuations.
496 * valprint.c (vtbl_ptr_name): Add final '\0'.
498 Fri Oct 25 16:06:38 1991 Stu Grossman (grossman at cygnus.com)
500 * tm-sparc.h, tm-68k.h (EXTRACT_RETURN_VALUE): fix output of
501 short return values for sparc and 68k. Patch from Paul Eggert.
503 * coffread.c, coredep.c, i386-xdep.c: install patches for
504 SysV/386 3.2 from Mauro DePalma.
506 Fri Oct 25 02:02:13 1991 John Gilmore (gnu at cygnus.com)
508 * core.c (core_file_info), exec.c (exec_file_info): Print file
509 type. Use printf_filtered.
511 * valops.c (value_fetch_lazy): Avoid 0-length fetches.
513 Thu Oct 24 23:06:40 1991 Fred Fish (fnf at cygnus.com)
515 * dwarfread.c: Add casts to remove compiler warnings.
517 * tm-3b1.h, tm-68k.h, tm-altos.h, tm-amix.h, tm-hp300bsd.h,
518 tm-hp300hpux.h, tm-isi.h, tm-news.h, tm-pn.h, tm-sun2.h,
519 tm-sun3.h: Remove locally duplicated code for calling functions
520 in the inferior. The only differences were in the specific trap
521 vectors used and whether or not an fpu was present. These are
522 now handled by appropriate definitions of BPT_VECTOR and
523 HAVE_68881 respectively. Other minor obvious cleanups.
525 * valops.c: Correct a minor misspelling.
527 * utils.c: Remove local BSD/USG hacks that are now in libiberty.
529 * dwarfread.c: Remove prototype for dwarfwarn. Does not work
532 Thu Oct 24 09:33:44 1991 John Gilmore (gnu at cygnus.com)
534 * stack.c (frame_command): Always print. Use new
535 frame_select_command to select a frame without printing.
537 * dwarfread.c: Use <varargs.h>, since <stdarg.h> is not portable.
539 Thu Oct 24 01:32:51 1991 Fred Fish (fnf at cygnus.com)
541 * dwarfread.c: New file for DWARF debugging format support.
543 * elfread.c: New file for ELF object file format support.
545 * procfs.c: New file for SVR4 /proc (process file system) support.
547 * tm-amix.h, xm-amix.h, tconfig/amix, xconfig/amix: New files for
550 * xm-svr4.h, tm-svr4.h: New files for SVR4 support.
552 * xm-m68k.h: New file for host machines with m68k cpu.
554 * Makefile.in: Add elfread.c and dwarfread.c to SFILES_MAINDIR.
555 Add elfread.o and dwarfread.o to OBS.
557 * symfile.h: Add "elf" to list of supported formats in comment.
559 * c-exp.y, defs.h, symtab.h, valprint.c: Add three new builtin
560 types to gdb, builtin_type_long_double, builtin_type_complex, and
561 builtin_type_double_complex. Add and use new TARGET_SHORT_BIT,
562 TARGET_INT_BIT, TARGET_LONG_BIT, TARGET_FLOAT_BIT,
563 TARGET_DOUBLE_BIT, TARGET_LONG_DOUBLE_BIT, TARGET_COMPLEX_BIT, and
564 TARGET_DOUBLE_COMPLEX_BIT, as the sizes in bits of the indicated
565 types on the target machine (ala the existing TARGET_LONG_LONG_BIT).
567 * infrun.c: When using SVR4 /proc interface instead of ptrace(),
568 call proc_set_exec_trap() to setup child to stop at first instruction.
570 * inftarg.c: When using SVR4 /proc interface, call proc_wait()
573 * m68k-tdep.c: Add new routines supply_gregset(), fill_gregset(),
574 supply_fpregset(), and fill_fpregset(), which are machine
575 dependent support routines for SVR4 /proc interface.
577 * utils.c: Add warning_setup() and warning(). Warning() behaves
578 the same as error() except that it returns normally rather than
579 jumping back to command level. Modules that don't want to call
580 warning() for some reason, but want to produce their own warnings,
581 can call warning_setup() to ensure compatibility with the way
582 warning() and error() deal with the terminal.
584 * symtab.c: Make internal errors produce more useful messages.
586 * tm-68k.h: Move code that is duplicated in almost every single
587 m68k based machine's configuration files to this common file.
588 Duplications in the configuration files still need to be removed
591 * infrun.c (child_create_inferior): System V versions must call
592 setpgrp() with no arguments, to comply with prototyping typically
595 * munch: Add support for SVR4 style nm output.
597 * dbxread.c, mipsread.c symmisc.c, symtab.c: Remove the object
598 file specific fields from the partial symbol table structure and
599 replace them with a pointer to private data for each different
600 flavor of object file reader to initialize appropriately.
602 Wed Oct 23 09:38:20 1991 John Gilmore (gnu at cygnus.com)
604 * xconfig/sun[34]os4: Add note about strstr botch on sunos4.0.3c
607 * mipsread.c (fixup_undef_type): New function. If a struct /
608 union / enum is defined in a header file but nowhere else used,
609 (by typedefing, pointer referencing or declaration) the mipsread code
610 builds the complete tree for the structure but leaves its code as
611 TYPE_CODE_UNDEF as it doesn't know what kind of aggregate it is.
612 Guess its type based on the details of the members.
614 Tue Oct 22 18:04:32 1991 Stu Grossman (grossman at cygnus.com)
616 * infrun.c (wait_for_inferior): Check return value from
619 Mon Oct 21 17:47:03 1991 Stu Grossman (grossman at cygnus.com)
621 * infrun.c (wait_for_inferior): fix stepi/nexti that was broken
622 by my last edit to this routine.
624 Mon Oct 21 14:27:43 1991 John Gilmore (gnu at cygnus.com)
626 * tm-sun3.h (FIX_CALL_DUMMY): problem with cross debugging.
627 FIX_CALL_DUMMY does unaligned accesses and/or forgets to byte swap
628 the values before putting them into the dummy code. (From Peter
631 Mon Oct 21 10:04:39 1991 Steve Chamberlain (steve at rtl.cygnus.com)
633 * configure.in: added ebmon target.
635 Wed Oct 16 22:49:58 1991 John Gilmore (gnu at cygnus.com)
639 * Makefile.in: Roll VERSION to 4.2.
640 * README, TODO, WHATS.NEW: Update.
642 * core.c (core_open): Improve error message for bad file.
643 Pass .reg virtual memory address to fetch_core_registers to help
644 it find the registers in the core-file header.
645 * coredep.c (fetch_core_registers): Take new argument, use it,
646 and pass it to register_addr to locate the block of registers.
647 * xm-mips.h: Update KERNEL_U_ADDR for new scheme. Cleanup a bit.
649 * dbxread.c (read_dbx_symtab, process_one_symbol): Handle
650 Sequent N_FN_SEQ like everybody else's N_FN.
652 * main.c: Circumvent SCO cc bug with #if !!defined(USG).
653 * tm-i386v.h: #endif guck.
654 * xconfig/i386*: Remove -Dgetpagesize()=4096 kludge.
655 * xconfig/i386sco: Add HAVE_STRSTR to avoid ANSI bdeath.
656 * xconfig/tahoe: Add REGEX, which seems to be missing.
658 * coredep.c: Add <sys/types.h> for SCOnix.
659 * dbxread.c (read_dbx_symntab): Avoid coredump on malformed file.
660 * printcmd.c (print_formatted): Flush output before disassembly.
662 Tue Oct 15 20:12:32 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
664 * doc/refcard.tex (sec "Working Files"): consistent metavars and
665 other improvements, due to comments by François Pinard
666 (pinard@iro.umontreal.ca)
668 * doc/gdb.texinfo (appendix "Installing GDB"): changes in
669 configure, and improvenets related to Pinard's refcard comments
671 Tue Oct 15 08:45:12 1991 John Gilmore (gnu at cygnus.com)
673 Changes from Fred Fish:
674 * tm-68k.h (FPI_REGNUM): Add.
675 * infrun.c (child_create_inferior): flush stdout and stderr
677 * configure.in: Handle amigados, amix hosts and targets.
678 * inflow.c: Handle TIOCGLTC_BROKEN for Amiga.
681 * values.c (show_convenience): Use printf_filtered.
682 * main.c (define_command): Check result of lookup_command for
684 (echo_command): Use printf_filtered, and force output out.
686 * dbxread.c (read_enum_type): Avoid Modula-2 kludge that breaks C
688 * i387-tdep.c (double_to_i387): Fix typo for double_to_ieee_extended.
689 * utils.c (_initialize_utils): If !ISATTY, don't paginate.
690 * configure.in, tconfig/decstation, xconfig/decstation: Rename
691 dec3100 to decstation.
693 Mon Oct 14 13:37:50 1991 Roland H. Pesch (pesch at cygnus.com)
695 * doc/gdb.texinfo: Catch up to changes recorded here in ChangeLog
696 (nodes Continuing and Stepping; Memory; Targets) clarifications
699 Fri Oct 11 23:27:06 1991 John Gilmore (gnu at cygnus.com)
701 * tm-{irix3,mips,nindy960,pn,symmetry,vx960}.h: Move
702 REGISTER_U_ADDR to corresponding xm- file. Sugg. by Peter Schauer.
704 * symmisc.c (print_partial_symtabs): Add printpsyms debug cmd.
706 * m68k-tdep.c (m68k_push_dummy_frame, m68k_pop_frame): Add
707 generic routines for calling inferior functions.
709 * blockframe.c (inside_main_scope, inside_entry_scope): New.
711 * copying.awk: Filter formfeeds out of copying & warrantee.
712 Make them available as `show copying' and `show warrantee' also.
713 * main.c (print_gnu_advertisement): Advt `show' commands.
715 Thu Oct 10 17:25:47 1991 John Gilmore (gnu at cygnus.com)
717 * mach386-xdep.c: Even when cross-compiling, leave in the
718 core-file reading code.
719 * core.c (get_core_registers): Avoid coredump if no .reg section.
721 Wed Oct 9 17:03:34 1991 John Gilmore (gnu at cygnus.com)
723 * mipsread.c, coffread.c: initialise TYPE_VPTR_FIELDNO to -1.
724 This avoids coredumps under `set print object on' in value_headof
725 (called erroneously by value_from_vtable_info) for `p &struct'
726 or `p *struct'. From Peter Schauer.
728 Mon Oct 7 00:06:52 1991 John Gilmore (gnu at cygnus.com)
730 * Makefile.in: Roll version to 4.1.2.
731 * dbxread.c: Use aout64.h, not a.out.gnu.h. Get external symbol entry
732 size from BFD (but, FIXME, we don't yet read external nlists's and
733 convert them to internal nlists's before handling them -- we still
734 assume they have the same size and alignment.) Use SET_NAMESTRING
736 * exec.c (exec_file_command): Move dead coff-encapsulation code
738 * m88k-tdep.c, m88k-xdep.c: Remove encap test and #inc <a.out.h>.
740 Fri Oct 4 22:30:06 1991 John Gilmore (gnu at cygnus.com)
742 * configure.in, tm-i386v.h, xm-i386v.h: Intel 386 Mach host port.
743 * xm-i386mach.h, mach386-xdep.c, xconfig/i386mach: New files.
745 Fri Oct 4 17:04:31 1991 Per Bothner (bothner at cygnus.com)
747 More patches from Peter Schauer <pes@regent.e-technik.tu-muenchen.de>:
748 * mips-xdep.c (store_inferior_registers): Don't try to
749 write the (pseudo) FP.
750 * mipsread.c (parse_partial_symbols): Improved algorithm for
751 setting pst->texthigh.
753 Fri Oct 4 16:47:32 1991 Roland H. Pesch (pesch at cygnus.com)
755 * doc/Makefile: make TEXINPUTS include . everywhere
757 Fri Oct 4 00:35:56 1991 John Gilmore (gnu at cygnus.com)
759 * coffread.c, dbxread.c, symfile.c, symmisc.c, symtab.h: Remove
760 vestiges of typevectors, which were for symsegs and are no longer
761 used. (From a question by Eliot Dresselhaus
762 <dresselh@RFT30.nas.nasa.gov>).
764 Thu Oct 3 09:33:26 1991 John Gilmore (gnu at cygnus.com)
766 * dbxread.c, coffread.c: static-ize functions that were
767 gratuitiously external. (From Fred Fish.)
769 * c-exp.y: sym->class to SYMBOL_CLASS (sym).
771 * dbxread.c (dbx_lookup_type): Keep doubling size of typevector
772 until it is large enough.
774 * dbxread.c (read_type): Handle error case slightly better.
775 Make complaint message not C++-specific.
777 Wed Oct 2 17:21:07 1991 Stu Grossman (grossman at cygnus.com)
779 * infrun.c (wait_for_inferior): Fix step/next so that you only
780 stop at the beginning of a new line. This fixes various problems
781 with for loops, nested if-else's and switch statements.
783 Tue Oct 1 06:33:55 1991 John Gilmore (gnu at cygnus.com)
785 * symtab.c (lookup_symtab_1, lookup_symbol): "fatal" errors
786 between symtabs and psymtabs become ordinary error()s.
788 * dbxread.c (read_dbx_symtab): Relocate end_of_text_addr
789 properly, making "end pc" correct in shared lib psymtabs.
790 (From Guy Harris <guy@auspex.com>.)
792 Mon Sep 30 13:15:31 1991 John Gilmore (gnu at cygnus.com)
794 * dbxread.c: Enable, but soften, const_vol_complaint.
795 (read_dbx_symtab): N_STSYM and N_LCSYM define static vars.
796 Ditto Gould N_NBSTS and N_NBLCS. Also, all types in the psymtab
797 should be file-scope, not global.
798 (read_struct_type): Remove ancient multiple-inheritance warning.
799 (read_range_type): Check base type, complain & patch if undefined.
800 * stack.c (frame_info): Demangle the function name in `info stack'.
803 Sat Sep 28 10:02:33 1991 John Gilmore (gnu at cygnus.com)
805 * eval.c (evaluate_subexp_for_address): Don't use
806 TYPE_POINTER_TYPE directly (it might be zero if this type has
807 never had a pointer created before); use lookup_pointer_type.
808 * symtab.c (lookup_method_type): Arguments were swapped in all
809 callers, so fix it here. I'm amazed this worked at all!
811 Fri Sep 27 18:09:31 1991 John Gilmore (gnu at cygnus.com)
813 * c-exp.y, m2-exp.y: Define more yysymbols that happen to be
814 "bss" rather than "data" symbols, but which still conflict.
817 * coffread.c (coff_symfile_read): Use xmalloc, not malloc.
818 * core.c (core_files_info): Shorten output.
819 * exec.c (exec_files_info): Ditto.
820 (build_section_table): Ignore zero-length sections.
821 * language.c, printcmd.c: Lint.
822 * language.h (get_frame_language): Declare.
823 * saber.suppress: update.
824 * stack.c (find_relative_frame): Remove complex code that was
825 #if 0'd, stick with simple code. Lint.
826 * saber.suppress: Update a bit.
827 * symfile.c (add_symbol_file_command): Add "?" to question.
828 * utils.c (parse_escape): Avoid \a due to bdead compilers.
829 * value.h: Declare typedef_print.
831 * valprint.c (val_print, type_print_base): TYPE_CODE_RANGE less
834 * nindy-tdep.c (nindy_frame_chain_valid): Use lookup_misc_func.
835 (Reported by Mark Peek <mark@imagen.com>.)
837 * solib.c (solib_map_sections): Relocate all sections, even
838 though only the text section's size is tracked. Mark ld_text
839 for eventual elimination as we generalize to N sections.
841 * infrun.c (wait_for_inferior): Don't check if the PC is in a
842 call_dummy if we were stopped by a random signal that is being
843 passed to the program. This produced wierd results when calling
844 functions in the inferior and signals (e.g. SIGALRM) were in use.
846 Tue Sep 24 18:05:30 1991 John Gilmore (gnu at cygnus.com)
848 * infrun.c (IN_SIGTRAMP): Not parenthesized properly.
849 Bugfix from Paul Eggert <eggert@twinsun.com>.
850 * tm-ultra3.h (IN_SIGTRAMP): Ditto.
851 * valprint.c (print_floating): Print 9 digits for IEEE floats.
854 Mon Sep 23 15:50:07 1991 John Gilmore (gnu at cygnus.com)
856 * Makefile.in: Roll VERSION to 4.1.1.
857 * source.c (line_info): Peter Schauer fixes a bug I introduced in
860 Fri Sep 20 16:10:52 1991 John Gilmore (gnu at cygnus.com)
864 * Makefile.in (VERSION): Set to 4.1.
865 * language.c (set_language_command): Print useful help message,
866 and restore the language string after giving help.
867 * valprint.c (typedef_print): Print typedef in C or M2.
868 * symtab.c (list_symbols): Use it.
869 * main.c (main): Avoid any output before (gdb) prompt when -q.
870 * language.c (set_language_command): Handle errors by restoring
871 the language string to its current state (fix from A. Beers).
872 * doc/gdbint.texinfo: Roll in information from README. Rearrange
873 "how to install" and "how to print the doc" stuff so it drops
875 * configure.in: Rename rtpc CPU to romp to match config.sub.
876 * README, WHATS.NEW, TODO: Update for gdb-4.1.
878 Fri Sep 20 17:39:14 1991 Roland H. Pesch (pesch at cygnus.com)
880 * doc/gdb.texinfo: Updates from ChangeLog. set/show write,
881 autoloading shared libs, copyright etc on GDB startup, clean up $_
882 and $__ index refs, set/show listsize and related updates to list
883 cmd. New host/target configs.
885 Fri Sep 20 15:46:00 1991 Roland H. Pesch (pesch at cygnus.com)
887 * doc/Makefile: generate aux version-no file doc/gdbVN.m4
888 from main Makefile.in version definition
889 doc/gdb.texinfo: use version recorded in doc/gdbVN.m4 for current
891 Makefile.in (setup-to-dist): generate doc/gdbVN.m4
893 * doc/gdb.texinfo: merge new language-switching and lang-specific
896 Fri Sep 20 15:00:57 1991 Per Bothner (bothner at cygnus.com)
898 * mcheck.c: Add __ONEFILE kludge to allow compilation by non-ANSI
899 compilers (which may lack stddef.h).
901 Fri Sep 20 13:29:42 1991 John Gilmore (gnu at cygnus.com)
903 * dbxread.c (read_dbx_symtab, process_one_symbol): N_FN and
904 N_WARNING are the same except for the N_EXT bit, so just use their
905 values alone, rather than OR-ing them with N_EXT.
907 Fri Sep 20 12:27:55 1991 Stu Grossman (grossman at cygnus.com)
909 * mipsread.c (parse_lines): Deal with negative extended line
912 * c-exp.y, m2-exp.y: #define yyerrflag and yynerrs to avoid
913 global symbol conflicts.
915 Fri Sep 20 02:28:15 1991 John Gilmore (gnu at cygnus.com)
917 * .gdbinit: Move 'set complaints' to top, so it runs even in
918 case we aren't debugging GDB.
919 * language.c (_initialize_language): Fix type check and range
920 check documentation strings.
921 * utils.c (!HAVE_VPRINTF): Define vfprintf as a function, so
922 language.c can use it. (Though language.c should really not be
923 handling warnings/errors the way it does, FIXME.)
924 * symtab.c (lookup_primitive_type): const lint.
926 Bugfix from Peter Schauer:
927 * source.c (lines_to_list): Make signed, to avoid comparison
928 going unsigned and complaining that -3 is too high for 21 lines.
929 * stack.c (lines_to_list): Ditto.
931 Thu Sep 19 23:33:41 1991 John Gilmore (gnu at cygnus.com)
933 * Makefile.in (HFILES): Add minimon.h.
934 (VERSION): Roll version number to 4.0.95.
935 (gdb.tar.Z, make-proto-gdb.dir, setup-to-dist, gdb-XXX.tar.Z):
936 New rules for building distributions. Normal distribution
937 is built by doing `make -f Makefile.in gdb.tar.Z' in the directory
938 one level up from here; it calls make-proto-gdb.dir to build a
939 directory `proto-gdb' which is an image of the release. The old
940 `gdb.tar.Z' rule still works too.
941 * config.sub, configure: Roll in latest from ..
943 Thu Sep 19 17:41:24 1991 Roland H. Pesch (pesch at cygnus.com)
945 * doc/gdbint.texinfo: Reorder contents; reorganize new-host,
946 new-target, and new-config chapters; fix minor typos; come closer
947 to usual GNU markup conventions for @file @samp @code @var.
949 Thu Sep 19 17:04:12 1991 Per Bothner (bothner at cygnus.com)
951 Patches from Peter Schauer <pes@regent.e-technik.tu-muenchen.de>:
952 * mipsread.c (parse_partial_symbols): Enter the name of all
953 structs/unions... into the psymtab so we can access them if the
954 symtab is not read in.
955 * mips-tdep.c: Remove some unneeded #includes.
956 * xconfig/dec3100: Add HAVE_STRSTR.
958 Thu Sep 19 15:14:23 1991 John Gilmore (gnu at cygnus.com)
960 * Makefile.in: Circumvent Sun Make bug on *-exp.tab.o.
961 * c-exp.y, m2-exp.y: Lint.
962 * m2-exp.y: Avoid using yytname[] which is a Bison-ism.
963 * valprint.c (val_print_fields): Check for stub type.
964 * mipsread.c (_initialize_mipsread): Avoid using
965 builtin_type_void at initialize time.
966 (mipscoff_symfile_read): use it now.
968 Wed Sep 18 15:55:51 1991 John Gilmore (gnu at cygnus.com)

1067 Tue Sep 17 08:37:41 1991 John Gilmore (gnu at cygint.cygnus.com)
1069 Add Andrew Beers' changes for Modula-2 support. His ChangeLog
1070 entries are enclosed herein. Not all of these changes
1071 have been merged into the master GDB sources -- check the
1072 ChangeLog above here for the merge log.
1074 Mon Jun 3 17:05:45 EDT 1991
1076 m2-exp.y Created. Tested outside of GDB for a few days. Proper
1077 operators were added, C specific operators and tokens
1078 removed. yylex() revamped to some extent. Still things
1079 missing from the grammar, such as sets.
1080 Tested for two weeks in GDB v3.5.
1082 Tue Jun 11 17:23:48 EDT 1991
1084 m2-exp.y Added boolean constants TRUE and FALSE to the grammar
1085 so they are built-in. Sort of a hack.
1087 Fri Jun 14 12:53:51 EDT 1991
1089 m2-exp.y Added range checking for numeric constants. Any numeric
1090 constant is assumed to be of builtin type INTEGER unless:
1091 (1) it is octal or hexadecimal, in which case it is a
1092 CARDINAL; (2) it is too big to fit into an INTEGER, in
1093 which case it is a CARDINAL.
1094 eval.c Added simple range checking for +, -, and * on integers.
1095 Doesn't work very well for *, since 6 * 1,000,000,000 =
1096 1,705,032,704, which fails the simple test of result >=
1097 first_operand, no matter in what order the operands are.
1099 Tue Jun 18 14:11:30 EDT 1991
1101 Broke the parser into parts, one containing the C grammar and the other
1102 containing code to be shared by all of the grammars.
1104 The following files no longer exist:
1109 The following files were added:
1111 c-exp.y (The C grammar)
1112 m2-exp.y (The Modula-2 grammar)
1113 parser-code.c (Code that is shared by the above grammar)
1117 Makefile.dist Changed to reflect the above dependencies. NOTE: It is
1118 now necessary to use the Bison compiler compiler, since it
1119 will generate function/variable prefixes other than yy.
1121 Tue Jun 18 16:47:49 EDT 1991
1123 symtab.[ch] Added the external variable working_lang, than holds the
1124 value of the current working language.
1125 Added the ennumerated type language_mode, with the values
1126 language_auto and language_manual, the former meaning that
1127 GDB sets working_lang as needed, and the latter meaning
1128 that the value of working_lang is totally under user
1130 symtab.[ch] Added the Modula-2 pervasive types INTEGER, CARDINAL,
1131 REAL, BOOLEAN and CHAR. Also added the type codes
1132 TYPE_CODE_BOOL and TYPE_CODE_CHAR.
1133 utils.c Added set_language_command and show_language_command to
1134 implement the GDB support commands "set language" and
1136 expression.h A number of identifiers were added to the type exp_opcode
1137 to facilitate Modula-2 builtin functions, integer
1138 division, and array indexing.
1140 Wed Jun 19 13:25:58 EDT 1991
1142 language.h Added the macro STRICT_TYPE, which evaluates to non-zero
1143 if the language specified by working_lang requires the use
1144 of strict typing of expressions. Eventually, even this
1145 will be able to be changed by the user.
1146 Added the macro RANGE_CHECK, which evaluates to non-zero
1147 if the language specified by working_lang requires the
1148 checking of a value against the domain of its type.
1149 Eventually, even this will be able to be changed by the
1151 language.[ch] Predicates involving types (simple_type, ordered_type,
1152 same_type, integral_type, numeric_type, character_type,
1153 boolean_type, float_type) are added. These predicates are
1154 based on the current value of working_lang, and are handy
1157 Wed Jun 19 15:39:34 EDT 1991
1159 eval.c Added the function type_array_rank which computes the rank
1161 valarith.c Added the funtion value_bool, which when given a integer
1162 value.h value (ie. struct value *) as an argument, it returns a
1163 boolean value (ie. struct value *) true if that integer
1164 is non-zero, and a boolean value false otherwise.
1165 valprint.c Added cases for TYPE_CODE_BOOL, so Modula-2 BOOLEAN values
1166 will print out properly.
1168 Wed Jun 19 16:36:34 EDT 1991
1170 valops.c Added the function value_capitalize, which returns it
1171 value.h argument capitalized if its argument is a lowercase
1172 letter, or the argument unchanged if its argument is not a
1174 valarith.c Added the function range_check_p, which returns non-zero
1175 value.h if its value argument is between the integral bounds upper
1177 Added the function range_check_enum_p, which makes sure
1178 that its value argument is a valid member of the domain of
1180 Added the function range_check_range_p, which makes sure
1181 its value argument lies between the upper and lower bounds
1182 of its type argument, which must be a ranged type.
1183 Added the function check_array_index, which range and type
1184 checks an index of an array.
1185 Added the function value_multi_subscript, which computes
1186 array[idx1,idx2...idxN], given a value array and an array
1187 of values representing indicies.
1188 values.c Changed value_from_long to work with TYPE_CODE_CHAR and
1189 unpack_long to work with TYPE_CODE_BOOL and
1192 Wed Jun 19 18:04:08 EDT 1991
1194 symtab.c Stored pervasive types in a structure and make
1195 lookup_pervasive_type() a lookup function that was based
1196 on working_lang. If lookup_pervasive_type() returned
1197 non-zero, then that value was returned (a fix, since
1198 before it simply wouldn't return the pervasive type.)
1199 language.h Added the macro CAST_IS_CONVERSION, which evaluates to
1200 non-zero if the language specified by working_lang means
1201 "conversion" when it says "cast".
1202 valops.c Added the function value_real_cast(), which performs a
1203 value.h *cast*, not a *conversion*, which is what value_cast()
1204 does when it can. In particular,
1205 value_cast(<float_type>,4) = 4.0, while
1206 value_real_cast(<float_type>,4) = some mess.
1207 eval.c Modula-2 builtin functions implemented: ABS, CAP, CHR,
1208 parser-code.c FLOAT, HIGH, MAX, MIN, ODD, ORD, TRUNC, and VAL.
1209 expression.h Added macros MAX_OF_TYPE and MIN_OF_TYPE to work with MAX
1210 and MIN on integral types. *NOTE*: These are currently
1211 hardcoded to work only if there are 8 bits per storage
1213 eval.c Made logical functions call value_bool to return a
1214 properly typed boolean value, based on working_lang.
1216 Thu Jun 20 11:55:27 EDT 1991
1218 valprint.c Types now print out in a Modula-2 fashion. This works for
1219 the cases when the type is printed out step-by-step, that
1220 is, it doesn't work when the name of a structured type
1221 (which includes the keyword "struct", etc.) is simply
1223 FIXME: Perhaps this is bad. Parts of it seem to kludgey,
1224 since type specifications in C and Modula-2 are very
1225 different. The C printing of a type is very recursive,
1226 whereas in Modula-2 it is generally very simple. C has
1227 type prefixes and suffixes, which have no real analogue in
1228 Modula-2. Maybe type_print() should call a language
1229 specific type printer. This is also advantageous if we
1230 compile GDB to exclude some of the languages. We'll just
1231 leave those functions out.
1233 Thu Jun 20 16:57:10 EDT 1991
1235 dbxread.c When reading the complete symbol table in (via
1236 psymtab_to_symtab()), the number and types of function
1237 arguments are added to a function type. define_symbol()
1238 calls add_param_to_type() to accomplish this.
1239 Assumption: when we come across a function definition
1240 (N_FUN symbol with an 'f' or 'F' in the name), its
1241 arguments will appear before another function definition.
1242 When a function is found, a pointer to its type is placed
1243 in the global in_function_type. Changes that
1244 add_param_to_type() makes are to this global.
1245 valprint.c The type of a function now includes (for Modula-2) the
1246 types of its parameters.
1247 eval.c Type checking and a check for the proper number of
1248 arguments is now done for function calls. Not sure of the
1249 impact this has on C++ member function yet.
1251 Thu Jun 20 19:58:48 EDT 1991
1253 valprint.c Rewrote the type printer. Broke it into two language
1254 specific parts, adding the functions type_print_m2() and
1256 An unfortunate consequence is this: if you debugging a C
1257 program in Modula-2 mode (why?), info types does not work
1258 well with regular expressions, since the types are printed
1259 out in Modula-2 terminology, but stored in C terminology.
1260 language.[ch] Added the functions new_type_last(), type_keyword(), and
1261 type_sep() to aid in the printing of typedefs.
1262 symtab.c Made the printing of typedefs as language independent as
1263 possible through calls to new_type_last(), type_keyword(),
1266 Fri Jun 21 11:50:26 EDT 1991
1268 dbxread.c Check all incoming ennumerated types. If it looks like
1269 Modula-2's BOOLEAN type, then change the type_code of the
1270 type to TYPE_CODE_BOOL so we can process it as a boolean
1272 valprint.c Replaced some of the 0x%x with calls to sprintf and
1273 hexformat() in val_print().
1274 language.[ch] Added the function hex_to_string(), which converts its
1275 integral argument to a hexadecimal number (format is
1276 language based) and returns the result as a string.
1278 Mon Jun 24 12:25:07 EDT 1991
1280 valprint.c Some functions call type_print_1() directly, instead of
1281 value.h using type_print(), so they can specify where (column) to
1282 print things. Since type_print() takes care of language
1283 dependence, that needs to be called first. Added a
1284 parameter depth to type_print() (so it is now like
1285 type_print_1). Changed type_print to type_print_at, and
1286 made type_print a macro that passes a depth argument of
1288 symmisc.c Changed all calls to type_print_1 to calls to
1290 Makefile.dist Made it possible to build GDB for a specific set of
1291 depend languages. Do this by passing a definition for the macro
1292 LANGS to make. LANGS should be a string containing a
1293 space-separated list of language names (ie. LANGS="c m2").
1294 The default is to build all languages. Note that grammar
1295 files must follow the naming convention of <lang>-exp.y.
1296 gdb.lang This holds the current value of the LANGS macro. It is
1297 examined every time make is called, and is updated if
1299 eval.c Added #ifdef _LANG_<lang> to these files.
1300 expread.c Still need to add them to dbxread.c and coffread.c.
1308 Mon Jun 24 16:33:11 EDT 1991
1310 language.[ch] Added the functions hexformat_pre() and
1311 hex_to_string_pre(), which take a prefix argument to
1312 include in the format string. Thus, hexformat_pre("08") will
1313 return "0x08x" (if the working language is language_c).
1314 Made hexformat() and hex_to_string() calls to the above
1315 with "" as the prefix argument.
1317 am29k-pinsn.c, arm-pinsn.c, breakpoint.c, convex-tdep.c, exec.c, core.c,
1318 dbxread.c, i386-pinsn.c, i386-stub.c, i386-xdep.c, i960-pinsn.c,
1319 infcmd.c, inflow.c, m68k-pinsn.c, m68k-stub.c, m88k-pinsn.c,
1320 mips-pinsn.c, mips-tdep.c, ns32k-pinsn.c, printcmd.c, pyr-pinsn.c,
1321 pyr-tdep.c, pyr-xdep.c, remote-vx.c, remote.c, solib.c, source.c,
1322 stack.c, sun386-xdep.c, symfile.c, symm-xdep.c, symmisc.c, tahoe-pinsn.c,
1323 valprint.c, vax-pinsn.c
1325 Changed all occurences of 0x%[0-9]*l*x in printf format strings to
1326 calls to hexformat() and hex_to_string(). Format strings without
1327 the leading "0x" were ignored.
1329 depend Updated to take the above into account.
1332 Tue Jun 25 15:27:18 EDT 1991
1334 symtab.h Added the types range_mode_t, range_check_t, type_mode_t,
1335 and type_check_t to keep track of the current state of
1336 range and type checking.
1337 main.c Added the variables range_mode, range_check, type_mode,
1338 and type_check to record the current state of range and
1339 type checking. Added initialization code to main().
1340 language.h Changed the macros STRICT_TYPE and RANGE_CHECK to examine
1341 the above variables.
1344 Tue Jun 25 17:57:08 EDT 1991
1346 dbxread.c process_one_symbol() updates the variable (enum language)
1347 source_lang based on the extension of the filename
1348 contained in the N_SO sybmol that started this symtab.
1349 When end_symtab() is called, the value of source_lang is
1350 put into the language field.
1351 stack.c select_frame() sets working_lang (and possibly type_check
1352 and range_check) to the language field of the symtab
1353 associated with the frame that is selected if working_mode
1354 is language_auto. If working_mode is language_manual, a
1355 warning is printed and working_lang is not set.
1356 language.c Added the function set_type_range(), which sets the value of
1357 type_check and range_check (if their modes call for
1358 automatic setting) based on the current value of
1359 working_lang. A non-zero argument will cause the current
1360 settings to be output.
1363 Wed Jun 26 14:51:40 EDT 1991
1365 eval.c Added range checks on assignment.
1366 m2-exp.y Added the grammar for sets to the language. Currently,
1367 these do not do anything except print an error message.
1369 Wed Jun 26 17:01:04 EDT 1991
1371 m2-exp.y Added the ability for parse_number() to parse negative
1372 numbers. A global flag is set upon encountering a unary
1373 minus. This was done to make, for example, 1 parse as a
1374 CARDINAL, and not as an integer, per Wirth's examples in
1375 Programming in Modula-2 ed.4.
1376 valprint.c Added support for "set radix 2" by then setting
1377 output_format to 't'.
1378 eval.c Implemented range checking on subrange types. Added calls
1379 to range_check_range_p for BINOP_ASSIGN and BINOP_VAL.
1380 Implemented MIN and MAX for ennumerated types. The
1381 minimum value of an ennumerated type is defined by Wirth
1382 as the first identifier, and the maximum as the last.
1383 m2-exp.y Made octal numbers ending with "B" be characters and those
1384 ending with "C" be numbers, per Wirth's book. (p. 34)
1386 Thu Jun 27 14:11:52 EDT 1991
1388 stack.c select_frame() now only sets working_lang, it does not
1389 notify the user. If working_mode is language_manual, then
1390 a warning is issued once.
1391 main.c At the end of each call to execute_command(), working_lang
1392 is checked against the local static (enum language)
1393 current. If they differ and working_mode is
1394 language_auto, the new settings of language, type and
1395 range checking are printed out.
1396 stack.c Modified frame_info() to include the language of the
1397 current frame in the output of "info frame".
1398 language.[ch] Added the function language_str() which returns the name
1399 of the current language.
1401 Fri Jun 28 15:33:14 EDT 1991
1403 m2-exp.y Added the built-in procedures INC, INCL, DEC, and DECL to
1404 the language. INCL and DECL currently cause an error,
1405 since sets are not implemented yet. INC and DEC are
1406 implemented as PREINCREMENT/PREDECREMENT with one
1407 argument, and as ASSIGN_MODIFY with two arguments.
1408 eval.c Added type checking to the above cases.
1409 value.h Added not_lval_constant to the lval_type ennumerated type.
1410 not_lval_constant means that the value is a constant
1411 value; that is 3 or 'a' or TRUE, not as in a constant
1412 identifier. This is used to help coerce numbers such as 3
1413 to either signed or unsigned numbers.
1414 valops.c Added the function value_coerce_constants() which coerces
1415 constant integers as following: if one is a constant and
1416 the other is not, the constant's type is set to the type
1417 of the other argument. If both are constants and one is
1418 signed, the other is converted to a signed constant.
1420 Sat Jun 29 17:26:29 EDT 1991
1422 valarith.c Added a better range checker. It now checks range
1423 (successfully) on integral operations [+-] (signed and
1424 unsigned) for any C sized type. Still does not work well
1425 for multiplication.)
1426 int_in_size() returns an integer that is coerced to fit into
1427 specified number of bytes.
1429 Mon Jul 1 13:04:14 EDT 1991
1431 language.[ch] Added the function binop_result_type(), which returns the
1432 builtin (struct type *) type that would be the result of a
1433 binop on the two values V1 and V2.
1435 Wed Jul 3 19:22:53 EDT 1991
1437 source.c Extended source_info() to include the source language in
1438 the output from "info source".
1440 Fri Jul 5 13:48:52 EDT 1991
1442 utils.c Moved the support functions for the GDB set/show commands
1443 dealing with language into language.c.
1444 language.c Added the function language_info(), which displays info
1445 about the current working language, type and range check
1446 settings. Called via the GDB command "info language".
1447 Added an initialization routine _initialize_language(),
1448 that sets defaults for the language, type and range
1449 variables and sets up the new GDB commands.
1450 main.c Language setup moved to language.c.
1453 Mon Jul 8 10:10:22 EDT 1991
1455 valarith.c Debugged the range checker for arithmetic. Still does not
1456 work for multiplication very well.
1458 Mon Jul 8 12:40:37 EDT 1991
1460 language.[ch] Added the function value_true() which returns non-zero if
1461 its argument represents a boolean true value.
1462 breakpoint.c Changed breakpoint_cond_eval() to call value_true() to
1463 check the truth of an expression.
1465 Thu Jul 11 12:51:34 EDT 1991
1467 language.[ch] Added the predicate structured_type(), which returns
1468 non-zero if the argument is a structured type.
1469 Added the predicate pointer_type(), which returns non-zero
1470 if the argument is a pointer type.
1471 eval.c Added the ability to do addition and substraction on
1472 pointers and integers. This case simply bypasses the
1475 Thu Jul 11 14:41:42 EDT 1991
1478 Added the symbol N_DEFD (0x4a) which is a definition
1479 module dependency that is used by the GNU Modula-2
1480 compiler and the linker. It is not important to GDB,
1481 except that [dbx|coff|mips]read.c should ignore these
1484 Fri Jul 12 16:07:00 EDT 1991
1486 valprint.c Changed the TYPE_LENGTH(type) >= 0 to TYPE_LENGTH(type) >
1487 0 in val_print(). Also added statements to the else part
1488 to coerce type (argument to val_print) to a pointer type
1489 if it is an "array of unspecified length".
1490 valops.c Added the function value_m2_string(), which returns a
1491 (value) value which is a constant string, whose type is
1492 (ARRAY [0..n] OF CHAR). The length field of the type
1493 structure is set to zero, so it will be interpreted as an
1494 "array of unspecified length".
1495 stack.c Moved the language/frame mismatch check to
1496 main.c:execute_command().
1497 main.c The working language is recorded each time
1498 execute_command() is executed. If working lang has
1499 changed during its execution, then the new
1500 language/type/range info is printed out for the user. If
1501 the working language does not match the language of the
1502 frame, a warning is issued.
1504 Sat Jul 13 16:16:39 EDT 1991
1506 eval.c Moved all the type-checking stuff for operators to
1507 language.[ch] language.c. This is so we can keep language-specific
1508 stuff (like for what type operators are defined) in
1510 language.[ch] Added the function binop_type_check(), which checks to see
1511 if its two (value) arguments are type-compatible with its
1512 opcode argument. The opcode should represent an operation
1513 involving an operator. Also added the macro function
1514 unop_type_check, which calls binop_type_check with a
1515 NULL second argument.
1516 expprint.c Added Modula-2 operators to the op_print_tab, so info
1517 expression.h break works correctly. Also added "op_string", which
1518 returns the string corresponding to the (enum exp_opcode)
1519 opcode that is its argument.
1522 Sat Jul 13 18:26:18 EDT 1991
1524 coffread.c Added code to record the type of function arguments with
1525 each paricular function. Code is very similar to that
1527 dbxread.c Moved add_param_to_type() to symtab.c
1528 symtab.[ch] Added function add_param_to_type() from dbxread.c
1530 *** NOTE: The above additions have not been tested.
1532 Mon Jul 15 12:50:47 EDT 1991
1534 langauge.[ch] Added the functions type_error and range_error, which work
1535 like error() except if the type/range mode is set to
1536 *_mode_warn, then they do not do a return_to_top_level(),
1537 but merely print a warning.
1538 Also changed [set|show]_[type|range]_command() to support
1539 the new "warn" feature.
1541 Thu Jul 18 17:50:54 EDT 1991
1543 mipsread.c Added code to record the type of function arguments with
1544 each particular function. Code is very similar to that
1547 *** NOTE: The above additions have not been tested.
1549 Fri Jul 19 11:19:10 EDT 1991
1551 defs.h Added macros MAX_OF_SIZE, MIN_OF_SIZE, UMAX_OF_SIZE, and
1552 UMIN_OF_SIZE, which when given a size of a numeric type,
1553 return the maximum and minimum value it can hold. UMAX...
1554 and UMIN... return the result for unsigned types.
1555 symtab.h Added the macros MAX_OF_TYPE and MIN_OF_TYPE to operate on
1556 struct types. They call above macros.
1557 dbxread.c Renamed the MAX and MIN_OF_TYPE macros to ..._OF_CTYPE to
1558 avoid a name conlict with the above.
1559 c-exp.y Added range checking on numeric constants in
1560 parse_number() for completeness.
1561 valarith.c Made binop_user_defined_p() and unop_user_defined_p()
1562 return 0 if working_lang is not language_c.
1564 Thu Aug 8 14:17:22 EDT 1991
1568 breakpoint.c Documentation strings of some commands changed to
1569 eliminate the references to the C language where
1572 Tue Aug 13 15:48:03 EDT 1991
1574 m2-exp.y Added qualified identifiers to the grammar. The semantics
1575 are slightly different from those of the GDB operator ::
1577 m2-exp.y Added a rule to each grammar of the form: start ::= exp |
1578 type_exp, where type_exp is any valid type expression.
1580 eval.c Added the opcode OP_TYPE, and an error case in eval.c.
1581 printcmd.c Modified ptype_command() so it actually parses the input
1582 (necessary for type expressions with scope qualifiers).
1583 Added the function ptype_eval() which expects an
1584 expression composed of one OP_TYPE element.
1585 *.[ch] Replaced all occurences of parse_c_expression with
1587 *.[ch] Replaced all occurences of parse_c_1 with parse_exp_1
1589 [End of ChangeLog entries from Andrew Beers for Modula-2 support.]
1591 Mon Sep 16 17:19:46 1991 John Gilmore (gnu at cygnus.com)
1593 Small fixes from Peter Schauer:
1595 * infrun.c (child_attach): Lint.
1596 * solib.c (find_solib): Handle shared libs version 2.
1598 Small fixes from David Wood:
1600 * xm-ultra3.h (SYS_SIGLIST_MISSING): Typo.
1604 * remote-vx.c: Move <stdio.h> to top, for FILE. Fix from
1605 John S <basrai%kanga.dnet@c3po.sm-alc.af.mil>.
1607 * utils.c (wrap_here): Avoid wrap action of fputs_filtered if
1608 chars_per_line is at maximum (user typed `set width 0'). Fix
1609 from Andreas Schwab <schwab@ls5.informatik.uni-dortmund.de>.
1611 Tue Sep 17 17:31:04 1991 Stu Grossman (grossman at cygnus.com)
1613 * coredep.c: include ptrace.h where necessary.
1614 * mipsread.c(parse_lines): fix unsigned char problem that was
1615 messing up line numbers on SGI's and possibly other MIPS based
1617 * infrun.c (child_create_inferior): use better test to check
1618 return val from setpgrp().
1619 * tm-irix3.h, xm-irix3.h, tconfig/irix3, xconfig/irix3: add these
1620 for sgi/irix support.
1622 Wed Sep 18 04:33:31 1991 Per Bothner (bothner at cygnus.com)
1624 * mipsread.c (parse_symbol): Put non-static procedures
1625 in the global block.
1627 Fri Sep 13 00:14:52 1991 John Gilmore (gnu at cygnus.com)
1629 Patch together `text_start' and `text_end' for 29K port.
1631 * exec.c (exec_command): If NEED_TEXT_START_END, define the
1632 variables and set them based on the exec file.
1633 * am29k-tdep.c: declare text_start.
1634 * valops.c (call_function_by_hand): declare text_end.
1636 * inferior.h: Eliminate CANNOT_EXECUTE_STACK in favor of
1637 defining CALL_DUMMY_LOCATION as BEFORE_TEXT_END. This is
1638 because machines that do this will also have to know to
1639 set NEED_TEXT_START_END. Besides, it was a redundant way to
1641 * tm-29k.h, tm-convex.h, tm-np1.h: Eliminate
1642 CANNOT_EXECUTE_STACK, define CALL_DUMMY_LOCATION and
1643 NEED_TEXT_START_END.
1645 Thu Sep 12 00:22:24 1991 John Gilmore (gnu at cygint.cygnus.com)
1647 AMD 29000 changes from David Wood <wood@david.ultra.nyu.edu>:
1649 * Makefile.in (CLIBS): Put XM_CLIBS and TM_CLIBS at end.
1650 Pass MUNCH_DEFINE to munch whenever we run it.
1651 * am29k-pinsn.c (print_insn): Handle NOP specially. Avoid %#x
1652 format string; use 0x%x instead.
1653 * am29k-tdep.c: Use DUMMY_SAVE_GREGS and RETURN_REGNUM.
1654 * ultra-xdep.c, xm-ultra.h: New files for Ultracomputer host system.
1655 * xm-rtbsd.h: New host support for RT/PC running BSD Unix.
1656 * inflow.c: Handle `short' process group IDs.
1657 * infptrace.c (fetch_register): Support CANNOT_FETCH_REGISTER,
1658 and check for ptrace errors.
1659 * coffread.c (SDB_REG_TO_REGNUM): Define if not already.
1660 (coff_symfile_init): Initialize text_bfd_scnum.
1661 (read_coff_symtab): Use it to find the text [and absolute?] sections.
1662 * ../config.sub: Add vendor nyu and os "sym[1-9]*".
1663 * configure.in: Add hosts rtpc-*-* and a29k-*-*.
1664 Merge target arm case with other "easy" cases. Add target
1665 cases a29k-*-none (rehack of am29k), a29k-*-kern (remote to
1666 Ultracomputer kernel), and a29k-*-sym1 (ultracomputer OS's user
1668 * minimon.h, remote-adapt.c, remote-mm.c: Add.
1669 * munch: Cope with RT/PC putting fns in data segment.
1670 Restore ability to override `nm' by specifying MUNCH_NM.
1671 * xconfig/rtbsd, xconfig/ultra3: New host systems.
1672 * tconfig/a29k: Rename from tconfig/am29k. Add remote-mm
1673 and remote-adapt. Remove encapsulated coff #define's (the
1674 support should go in BFD, and gdb shouldn't know or care).
1675 * tconfig/a29k-kern: Same, but for remote kernel debugging.
1676 * tconfig/ultra3: For debugging user processes on Ultra3/Sym1.
1677 * tm-29k.h: Update BADMAG (though it should go away).
1678 Allow the register definitions to be overridden in another
1679 tm-file. Fix SR_REGNUM. Add a mess of _REGNUM's. Separate
1680 RETURN_REGNUM from GR96_REGNUM and DUMMY_SAVE_GREGS from
1681 DUMMY_SAVE_GR96, for handling kernel calling conventions
1682 that use GR64+ rather than GR96+.
1683 * tm-ultra3.h: New file, for use on Ultra3 Unix as well as for
1684 remote debugging of Ultra3 kernel. Includes tm-29k.h and
1685 overrides various things.
1687 * remote-mm.c (mm_attach, mm_wait): Handle attach like
1688 child_attach does, making a clean stop in the newly attached
1690 * remote-eb.c: Lint.
1692 * coffread.c: Make coffread independent of any particular
1693 variant of COFF. Avoid #include-ing any particular one except
1694 internalcoff.h. BFD now passes key values for symbol reading
1695 as part of its coff_data structure (LINESZ, SYMESZ, AUXESZ,
1696 and the symbol masks and shifts); use them.
1697 Remove obsolete end_of_text_addr.
1699 * exec.c: Remove unused include files.
1701 Wed Sep 11 19:38:44 1991 John Gilmore (gnu at cygint.cygnus.com)
1703 * Makefile.in (documentation targets): Pass $(M4).
1704 Bugfix from eggert@twinsun.com (Paul Eggert).
1706 * stack.c (down_silently_command): Check for stack existence.
1708 Tue Sep 10 23:08:29 1991 John Gilmore (gnu at cygint.cygnus.com)
1710 * Makefile.in (VERSION): Update to 4.0.3.
1712 Tue Sep 10 09:19:29 1991 John Gilmore (gnu at cygint.cygnus.com)
1714 * core.c (core_file_command): Print frame at coredump with
1715 its level number, by calling print_stack_frame.
1716 * frame.h: Add selected_frame_level, print_stack_frame.
1717 * frame.h, stack.c: Remove print_sel_frame, print_selected_frame.
1718 * convex-tdep.c, convex-xdep.c, infcmd.c, inflow.c, infrun.c:
1719 Change print_sel_frame and print_selected_frame callers to
1722 * dbxread.c (read_ofile_symtab): Avoid empty else clause.
1723 * symfile.c (free_named_symtabs): Ditto.
1724 * main.c (main): wrap_here needs an arg.
1725 * solib.c (find_solib): Avoid memory access if _DYNAMIC is zero.
1726 (solib_add): Avoid noise.
1727 (solib_create_inferior_hook): Lint.
1728 (sharedlibrary_command): Move dont_repeat to here.
1729 * utils.c (error): Call wrap_here to force buffered output.
1731 Small patches from Peter Schauer:
1733 * coffread.c (start_symtab): Free any existing line_vector before
1735 (read_coff_symtab): Ditto for type_vector.
1737 * source.c (lines_to_list): New variable, replacing function.
1738 (all uses): Use as variable.
1739 (_initialize_source): Add 'set listsize' and 'show listsize'.
1740 * utils.c (lines_to_list): Remove function.
1741 * stack.c (print_frame_info): Use as variable.
1742 * defs.h (lines_to_list): Remove declaration.
1744 Mon Sep 9 13:45:57 1991 John Gilmore (gnu at cygint.cygnus.com)
1746 * breakpoint.c (insert_breakpoints): Restore warning about
1747 the program might be running in another process, but only for
1748 systems with this brain death (#ifdef ONE_PROCESS_WRITETEXT).
1749 * xm-hp300bsd.h, xm-mips.h, xm-vax.h: Define it.
1751 * utils.c (error): if error_pre_print is set, print the string
1753 * main.c (main, print_gnu_advertisement, print_gdb_version):
1754 Reformat legalese so it always prints, but acts as an "I'm here"
1755 message while symbols are being read. If any errors occur,
1756 print a few newlines to set off the message and start it at the
1757 left margin. Remove mention of "help" command, and don't yak
1758 about symbol reading.
1759 (catch_errors): Error string is now printed first in case of
1761 * command.c (undef_cmd_error, lookup_cmd): On undefined command,
1762 suggest the "help" command.
1764 * Makefile.in (VERSION): Set to 4.0.2.
1766 Thu Sep 5 23:49:48 1991 John Gilmore (gnu at cygint.cygnus.com)
1768 * .gdbinit: Remove useless "rr" command. Set complaints
1769 to 1 for people debugging gdb.
1771 * breakpoint.c, remote-vx.c: Reword strings printed by
1772 catch_errors callers.
1774 Wed Sep 4 11:07:50 1991 John Gilmore (gnu at cygint.cygnus.com)
1776 * WHATS.NEW: "history write -> history save". Doc "write on/off".
1777 (Fix from kenc@viewlogic.com.)
1779 Fix some infrastructure to be able to cope with host and target
1780 machines with different sized basic types (ints, ptrs, etc).
1781 (Idea from pierre@la.tce.com (Pierre Willard).)
1783 * values.c (value_from_longest): Rename from value_from_long.
1784 Handle pointer types as well as integers, so that targets with
1785 different pointer sizes from the host can be accomodated.
1786 * breakpoint.c, convex-tdep.c, eval.c, expprint.c, printcmd.c,
1787 valarith.c, valops.c, valprint.c, value.h, values.c: Rename
1788 uses of value_from_long to value_from_longest.
1789 * eval.c, findvar.c, printcmd.c, valarith.c, valops.c: Pass
1790 the correct pointer type to value_from_long{est}.
1792 * doc/gdb.texinfo ($_, $__): Describe types of these variables.
1794 * remote-vx.c: Remove obsolete code for calling functions via
1795 vxworks kludge interface (it referenced value_from_long).
1797 * valops.c (value_string): Find malloc with lookup_misc_func, not
1800 Tue Sep 3 18:37:46 1991 John Gilmore (gnu at cygint.cygnus.com)
1802 Make writing to files work properly. (Fixes to BFD are also needed.)
1804 * core.c (core_open): Open file ourselves, read or r/w, depending on
1805 write_files. Use bfd_fdopenr.
1806 * gdbcore.h (write_files): New variable.
1807 * exec.c (write_files): Define variable, add set&show for it.
1808 (exec_file_command): Use write_files to open for read or r/write.
1810 Make shared library reading happen automatically. These changes
1811 are mostly from Peter Schauer <pes@regent.e-technik.tu-muenchen.de>.
1813 * inferior.h (stop_soon_quietly): Add to exported variables.
1814 * infrun.c (child_create_inferior): call solib hook, if defined.
1815 (child_attach): call solib hook, if defined.
1816 * solib.c: Include inferior.h. Add from_tty to so_list as kludge.
1817 (find_solib): Use lookup_misc_func rather than hand-rolled.
1818 (symbol_add_stub): New stub for catch_errors.
1819 (solib_add): Avoid output if !from_tty. Catch errors rather
1820 than just calling symbol_file_add and bombing.
1821 (solib_create_inferior_hook): Interface with the target process
1822 to let it read and alloc shared libs, then figure out what it did.
1824 * core.c (validate_files): Fix typo, soften warning.
1825 (Fix from Hiroto Kagotani <kagotani@cs.titech.ac.jp>.)
1827 * utils.c (fputs_demangled): Avoid duplicate printing if
1828 demangling is off. (Fix from J.T. Conklin <jtc@cayenne.com>.)
1830 * infrun.c (proceed): Cast -1 to (CORE_ADDR) before comparing.
1831 (Fix from pierre@la.tce.com (Pierre Willard).)
1833 * main.c (catch_errors): Change argument to a char * from an int,
1834 since a char * can point to a struct full of glop, but an int
1835 is not guaranteed to be able to hold a pointer.
1836 * breakpoint.c (breakpoint_cond_eval, bpstat_stop_status,
1837 breakpoint_re_set_one, breakpoint_re_set): Adapt.
1838 * core.c (core_open, solib_add_stub): Adapt.
1839 * remote-vx.c (symbol_stub, add_symbol_stub, callers): Adapt.
1841 Wed Aug 28 18:18:05 1991 John Gilmore (gnu at cygint.cygnus.com)
1843 * Makefile.in: Update VERSION to 4.0.1. Evade GNU Make bug
1844 by adding .NOEXPORT target.
1846 Fri Aug 23 17:14:25 1991 John Gilmore (gnu at cygint.cygnus.com)
1850 * Makefile.in (VERSION): Roll to 4.0.
1851 (gdb.tar.Z): Make refcard.ps as well, for shipment.
1853 Fri Aug 23 14:07:09 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1855 * doc/gdb.texinfo: minor rewordings, crossref to ptype from print,
1858 * doc/Makefile, Makefile.in: generate "gdb-all.texi" rather than
1861 * doc/rdl-apps.texi: renamed from rdl-apps.texinfo
1863 * Makefile.in, doc/Makefile, doc/.Sanitize, doc/gdb.texinfo:
1864 reflect above name change
1866 * WHATS.NEW: correct pointer to refcard.
1868 * doc/gdb.texinfo: update New Features, Installing
1870 * doc/gdbint.texinfo: add short description of configure +template
1872 Fri Aug 23 11:46:08 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1874 * doc/gdb.texinfo: update, fix bugs in "Installing" appendix
1876 Fri Aug 23 01:02:00 1991 John Gilmore (gnu at cygint.cygnus.com)
1878 * Makefile.in: Add config.sub, make doc/rdl-apps.texinfo for
1879 tar file, add dependencies for referenced doc files.
1881 Thu Aug 22 22:17:06 1991 Stu Grossman (grossman at cygint.cygnus.com)
1883 * coffread.c, symfile.c, stack.c: saberized.
1885 Thu Aug 22 16:20:27 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1887 * doc/refcard.tex: permuted Essential Commands sec
1889 * doc/gdb.texinfo: new C++ chapter; revised installation appendix;
1891 set/show symbol-reloading
1892 default set complaints 0
1894 RET-repeat disabled after prompted long displays
1895 processID (attach) interpretation of 2nd GDB cmdline arg
1897 Thu Aug 22 14:05:47 1991 Stu Grossman (grossman at cygint.cygnus.com)
1899 * expread.y, coffread.c, dbxread.c, target.c, mem-break.c,
1900 cplus-dem.c, values.c, valprint.c, symfile.c, remote.c,
1901 breakpoint.c, main.c: lint.
1903 Thu Aug 22 02:02:26 1991 John Gilmore (gnu at cygint.cygnus.com)
1905 Install new configuration scheme for GDB and friends.
1907 * config.sub: Translate ordinary names to three-part names.
1908 * configure: Use three-part names internally.
1909 * configure.in: Translate three-part names to filenames.
1911 * README, WHATS.NEW: Update for gdb-4.0.
1912 * Makefile.in: Roll VERSION to 3.99.
1914 Wed Aug 21 18:21:09 1991 John Gilmore (gnu at cygint.cygnus.com)
1916 * infptrace.c (KERNEL_U_ADDR_BSD): Include a.out.gnu.h.
1917 * i960-tdep.c, m68k-tdep.c, sparc-tdep.c, tm-i960.h,
1918 tm-m68k.h, remote-nindy.c: Change ext_format_XXX structs
1919 to single structures rather than arrays; when passing
1920 their address, use &. This avoids trouble with bdead compilers.
1921 * mcheck.c: Don't include <stdlib.h>; just declare "void abort();"
1922 instead. This avoids portability headaches.
1923 * mips-tdep.c (mips_do_registers_info): Only print FP regs if
1925 * source.c (open_source_file): Avoid ANSI const bdeath by
1926 skipping declaration and then casting result value.
1927 * tm-hp300bsd.h: Clarify comment.
1928 * utils.c (strstr): Result is const char *; ANSI bdeath.
1929 * xm-hp300bsd.h: Define HOST_BYTE_ORDER. Redefine INT_MIN,
1930 since system include file defines it differently from "defs.h",
1931 though the two are equivalent for our purposes.
1932 * tconfig/hp300bsd: Add m68k-tdep.o.
1934 Tue Aug 20 16:01:11 1991 John Gilmore (gnu at cygint.cygnus.com)
1936 * tconfig/sun*4: Remove warnings about system assembler.
1938 Mon Aug 19 13:44:46 1991 John Gilmore (gnu at cygint.cygnus.com)
1940 * mcheck.c: Avoid warning about undeclared abort fn.
1941 * tm-sparc.h (PC_ADJUST): Avoid calling error() from this;
1942 it causes recursive calls to error() when used in cleanups.
1943 To do so requires that we make it a function, so we do.
1944 * sparc-tdep.c (sparc_pc_adjust): New implem of PC_ADJUST.
1945 * utils.c (do_cleanups): Remove the current cleanup from the
1946 chain *before* calling it, in case error() is called from it.
1947 The result won't be pretty, but won't be an infinite loop either.
1949 Mon Aug 19 00:41:04 1991 Michael Tiemann (tiemann at cygint.cygnus.com)
1951 * dbxread.c (read_struct_type): Grok anon structs for C++.
1952 (vb_name, vptr_name): Null terminate these strings.
1954 Fri Aug 16 08:31:03 1991 John Gilmore (gnu at cygint.cygnus.com)
1956 Minor bug fixes from BSD Net2 gdb:
1958 * blockframe.c (get_prev_frame_info): If FRAME_CHAIN_COMBINE
1959 returns 0, there is no previous frame.
1960 * breakpoint.c (commands_command): If !from_tty, don't call
1961 input_from_terminal_p().
1962 * dbxread.c (record_misc_function): Speed up slightly.
1963 (compare_psymbols): Ditto.
1964 * infcmd.c (do_registers_info): Take a second argument to
1965 determine whether to print float registers. "info registers"
1966 does not do so anymore. "info all-registers" does, now.
1967 * mips-tdep.c, pyr-tdep.c (xxx_do_registers_info): Take second
1969 * tm-mips.h, tm-pyr.h (DO_REGISTERS_INFO): Pass second arg.
1970 * inflow.c (initialize_inflow): Set tflags_ours correctly.
1974 * breakpoint.c (bpstat_do_actions): Use a cleanup to restore
1975 executing_breakpoint_commands if we are interrupted by error.
1976 * coffread.c (init_lineno): Avoid problem with zero-sized linetab
1977 versus malloc/free. From: john@labtam.labtam.oz.au (John Carey).
1978 * core.c (solib_add_stub, core_open): Call SOLIB_ADD inside a
1979 catch_errors() so we can setup the frame regardless of whether
1980 the shared libs work.
1981 * ieee-float.c (double_to_ieee_extended): Get exponent from
1982 right place in little-endian systems. From John Carey.
1984 Thu Aug 15 18:43:57 1991 John Gilmore (gnu at cygint.cygnus.com)
1986 * main.c: Remove unused terminating_signals and catch_termination().
1987 (long_options): Terminate with a zero element.
1988 [Bugfix from Atsuo Kawaguchi <atsuo@hark86.harl.hitachi.co.jp>.]
1989 (gdb_readline): Make call-compatible with readline.
1990 (init_signals): Improve comments re vfork vs. signal.
1992 * utils.c (prompt_for_continue): Use new gdb_readline().
1993 If we prompt for continuation, we don't let CR repeat the previous
1994 command, once we get back to a prompt. It's too easy to keep
1995 hitting CR, expecting "--more--" prompts, and have some long
1996 command start repeating on you.
1998 Tue Aug 13 16:17:56 1991 John Gilmore (gnu at cygint.cygnus.com)
2000 * blockframe.c (frameless_look_for_prologue): Speed up by
2001 calling SKIP_PROLOGUE_FRAMELESS_P if it's defined.
2002 * tm-sparc.h (SKIP_PROLOGUE, SKIP_PROLOGUE_FRAMELESS_P):
2003 Define two variants, one faster.
2004 * sparc-tdep.c (sparc_frame_chain): Use target_read_memory
2005 and return zero, rather than giving an error.
2006 (setup_arbitrary_frame): Initialize the PC in the new frame.
2007 (skip_prologue): Add a second arg saying whether we're just
2008 checking for a frameless function or not.
2010 * core.c (core_open, core_close, core_xfer_memory): Move
2011 section table pointers and bfd* into the target_ops.
2012 (core_open): Allow errors in shared lib reading, etc.
2013 (core_files_info): Describe shared library sections.
2015 * exec.c (exec_open, exec_close, exec_xfer_memory, xfer_memory,
2016 exec_files_info, set_section_command): Move section table
2017 pointers and bfd* into the target_ops.
2018 (add_to_section_table): Add BFD to section table.
2020 * target.c (target_xfer_memory, target_info): Pass target to
2021 xfer_memory and target_info functions.
2024 * gdbcore.h: Move struct section_table.
2025 * target.h: New home of struct section_table.
2027 * solib.c (solib_add): New argument is the target_ops whose
2028 section list is to be added to, if any. Reallocate the
2029 sections in that target to add any that come from shared libs.
2030 (throughout) so_sections renamed to sections.
2031 (solib_xfer_memory): Deleted.
2032 * tm-sunos.h (SOLIB_ADD): Add target argument.
2033 (SOLIB_XFER_MEMORY): Delete.
2035 * core.c, exec.c, inftarg.c, remote-eb.c, remote-nindy.c,
2036 remote-vx.c, remote.c, target.c, target.h: Remove add_syms vector
2037 from target_ops. It's the same on all targets. Add two section
2038 pointers to target_ops.
2040 * stack.c (find_relative_frame): Dump ancient algorithm for
2041 "down", just use handy "next" pointers.
2042 (frame_command): Don't error if there is no stack; let user
2045 * inflow.c (new_tty_prefork, new_tty): New prefork routine
2046 modifies static state in the parent process; new_tty itself
2047 runs in the child and modifies the child's file descriptors
2048 to match the saved static state.
2049 * infrun.c (child_create_inferior): Call new_tty_prefork,
2052 * infptrace.c (child_xfer_memory): Add ignored target arg.
2053 * remote-eb.c (eb_xfer_inferior_memory): ''
2054 * remote-nindy.c (nindy_xfer_inferior_memory): ''
2055 * remote-vx.c (vx_xfer_memory): ''
2056 * remote.c (remote_xfer_memory): ''. Rename from
2057 remote_xfer_inferior_memory.
2059 * main.c (main): Only try to attach "corefile" argument if
2060 it starts with a digit.
2062 * symfile.c (symbol_reloading): New "set/show" variable.
2063 (symbol_file_add): Shorten message about symbol reading.
2064 (add_symbol_file_command): Merge with add_syms_addr_command,
2065 since this should work on all targets now.
2066 (stop_whining): Default to zero, to shut up complaints
2067 about bad symbol tables on many systems.
2068 (free_named_symtabs): Just exit unless symbol_reloading.
2070 * xm-sun3os4.h, xm-sun4os4.h: Define BROKEN_LARGE_ALLOCA,
2071 and add comment explaining shared library screw.
2073 * source.c: #if defined => #ifdef.
2075 Thu Aug 8 12:23:19 1991 John Gilmore (gnu at cygint.cygnus.com)
2077 * doc/gdbint.texinfo: Improve doc on porting to new OS's.
2079 Tue Aug 6 17:16:15 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
2081 * doc/rdl-apps.texinfo: provide default readline-appendix finder
2082 (doc/Makefile knows how to make one for local config)
2084 * Makefile.in: use doc/Makefile for doc targets
2086 * doc/Makefile: GDB documentation now has its own Makefile
2087 doc/refcard.tex: renamed from "gdbrc.tex"
2088 doc/.Sanitize: add Makefile; recognize renamed refcard.tex
2089 doc/gdbint.texinfo: add markup in "Cleanups" chapter
2092 Fri Aug 2 00:13:06 1991 John Gilmore (gnu at cygint.cygnus.com)
2094 * values.c (baseclass_addr): When reading target memory, use the
2095 length of the basetype, not the upper type. We've only malloc'd
2096 enough space for the basetype, leading to errors in free().
2098 * expprint.c (print_subexp): Print UNOP_MEMVAL of an OP_LONG that
2099 ends up as a function specially, since we know the actual type of
2100 the pointed-to address. This (somewhat) fixes display of
2101 expressions that include misc_function_vector names. Try `cond 1
2102 !strcmp("a","b")' then `i b'.
2104 * infrun.c: Move DO_DEFERRED_STORES from proceed() to resume().
2105 The child can be proceeded from inside wait_for_inferior in
2106 evaluating breakpoint conditions, and DO_DEFERRED_STORES was
2107 getting skipped in that case.
2109 * expprint.c (print_subexp): Use filtered output, since the
2110 subroutines we call use it, otherwise the output is horribly
2111 mangled, since output of wrappable stuff comes out late.
2113 * Makefile.in: Bump VERSION to 3.98.1
2115 * infrun.c (child_create_process): Use execlp to find the
2116 shell to exec our target program. This requires some fiddling
2117 with `environ' since there is no execlpe().
2119 Thu Aug 1 15:35:17 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
2121 * Makefile.in, doc/gdbrc.tex, doc/rc-* (new files):
2122 Minor rearrangement of refcard permits two new make targets--
2123 gdbrc.dvi DVI output for refcard, using CM fonts
2124 gdbrc.ps PostScript refcard, using PS fonts
2126 Wed Jul 31 16:46:21 1991 John Gilmore (gnu at cygint.cygnus.com)
2130 * TODO, Projects, WHATS.NEW, README: Update for gdb-3.98.
2131 * Makefile.in (gdb-all.texinfo): Avoid touching file if M4 dies.
2133 Wed Jul 31 16:35:58 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
2135 * doc/gdb.texinfo: last changes for release.
2136 Minor typo and formatting fixes; incorporated most fixes remaining from
2137 filed mail commenting on earlier drafts.
2139 Added warnings: pipes don't work in run command;
2140 conditions are converse of assertions;
2141 step over fn without debug info goes to next fn;
2142 vars may have "wrong" values near fn entrance, exit
2144 Added example from Kingston on printing repeated nonadjacent values
2146 Added explicit mention that in Emacs gdb mode C-c and C-z are like
2147 shell mode for signals
2149 Renamed "Stepping and Continuing" to "Continuing and Stepping" so it
2150 doesn't sound so much like its parent "Stopping and Continuing"; also
2151 moved entries on continue to top of section, so they don't get lost.
2153 Improved installation directions in appendix, added manual formatting
2156 Tue Jul 30 17:26:39 1991 John Gilmore (gnu at cygint.cygnus.com)
2158 * configure.in: Remove xm.h and tm.h even if we aren't linking
2159 new ones, so "./configure sun4; ./configure none" does the right
2160 thing. Assume that alldeps.mak and depend are already built in
2161 srcdir, and avoid running "make" (particularly "make depend",
2162 which involves "gcc") from inside configure. Build Makefile
2163 directly rather than building Makefile.conf first.
2164 * configure: Regenerate with above changes.
2165 * Makefile.in: Use $(BISON) to find bison. Roll VERSION
2166 to 3.98. Revise gdb.tar.Z procedure to produce a file
2167 called gdb-$(VERSION).tar.Z but which unpacks into a
2168 directory called "gdb". Move non-source files out of
2169 $(SFILES_SUBDIR). Pretty up alldeps.mak with comments.
2170 (depend): Don't try to do "gcc expread.y".
2171 (expread.o): Update dependencies by hand.
2173 Mon Jul 29 15:21:09 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
2176 Fixed a variety of small typos that prevented info from formatting
2177 cleanly; altered too-long heading for GPL Appendix, as discussed
2178 w/RMS; Changed date on cover to July 91.
2180 Fri Jul 26 13:20:02 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
2183 (1) Applied some fixes due to comments from Larry Breed (easier ones
2184 through chapsec 5.2)
2185 (2) Eliminated use of @footnote---had my doubts about it anyways, and
2186 it's broken in latest texinfo
2187 (3) Introduced *some* use of [] for optional arguments, where
2188 explanation is not simpler by listing cmd w arg and cmd w/out arg
2189 separately. Still not using @deffn.
2190 (4) Dropped in GPL-2. NOTE: one of GPL-2 or texinfo is broken; a
2191 couple of headings are too long. Need patches to texinfo or revision
2194 * Partial update to README (which still needs work for this
2195 release!): (1) use of configure corrected for new script,
2196 (2) "make gdb.dvi" and "make gdb.info" mentioned.
2198 Wed Jul 24 06:44:02 1991 John Gilmore (gnu at cygint.cygnus.com)
2200 * symtab.c (lookup_symbol): Don't complain right off about
2201 no debug symbols; use the misc function vector first.
2202 (list_symbols): Use misc function vector to find symbols
2203 that don't have debug info, and print them.
2204 (find_pc_symtab): Temporarily avoid fatal() when psymtab
2205 PC range doesn't match symtab PC range, as it does on the
2206 MIPS because our symtab reading isn't perfect.
2208 * dbxread.c (dbx_symfile_read): Make warning about
2209 "no debug symbols" slightly nicer.
2211 * source.c (select_source_symtab): If "main" symbol exists,
2212 but decode_line_spec can't find line info, don't just return
2213 a zero; try other source symtabs or give an error.
2215 * mipsread.c (parse_partial_symbols): Sort the psymtabs by
2216 their low addresses first, then rip through fixing high addrs.
2218 * ns32k-opcode.h (sfsr): Bugfix from Rune Nerg}rd,
2219 <runene@ifi.uio.no>.
2220 (NS32K_SVC_IMMED_OPERANDS): Reverse the #ifndef.
2222 Tue Jul 23 18:52:43 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
2224 * Minor, mostly mechanical, cleanup of doc subdir for clean
2225 makeinfo'ing and TeXing; also ensured gdb-all.texinfo (post-m4)
2226 and gdb.info (post- texinfo2 makeinfo) generated for distribution.
2228 Sun Jul 21 03:54:52 1991 John Gilmore (gnu at cygint.cygnus.com)
2230 Mostly MIPS and general symbol-reading fixups.
2232 * doc/gdbint.texinfo: Add documentation on symbol-reading
2235 * mipsread.c: Remove kludges around #include "ecoff.h".
2236 Remove redefinitions of a_magic, etc, no longer used.
2237 (parse_symbol, ): Convert "Internal:" printfs to complain()ts.
2238 Fix global overview comments to match symfile.c protocol.
2239 (mipscoff_new_init): Eliminate cur_hdr if we have one.
2240 (mipscoff_symfile_read): Eliminate unused code. Avoid
2241 sorting all the symtabs, when all we have read here is psymtabs.
2242 The symtabs are sorted as they are created anyway. Tell
2243 condense_misc_bunches whether we're mainline.
2244 (psymtab_to_symtab_1): Pass filename when recursing, to make
2245 stack trace more informative.
2246 (parse_partial_symbols): Assume cur_hdr as argument.
2247 (read_mips_symtab): Don't clobber cur_hdr, so it can be freed.
2248 Pass cur_hdr implicitly to parse_partial_symbols. Avoid checking
2249 the TYPE_NAME of char *, since that's done in symfile.c.
2250 (free_numargs, parse_symbol, add_symbol, add_block,
2251 shrink_linetable): Declare these fns void.
2252 (upgrade_type): Convert tree of if's to switch. Clean up
2253 bogus "off == 0" handling with a complaint. Avoid setting
2254 field bitpos and bitsize of array with lower and upper bounds.
2255 Check specified bitsize of elements against their actual type's
2256 bitsize, and complain if different. Complain about unknown
2258 (parse_fdr): Don't assume sizeof(char *) == sizeof (struct *).
2259 (psymtab_to_symtab_1): Print names of subsidiary files that
2260 are being read in. FIXME, we read far too many files. This code
2261 is not the problem, the problem is in parse_fdr where the psymtabs
2263 (cross_ref): Result should indicate that we used one aux entry
2264 normally, or two if we encountered a "next" entry. This used
2265 to leave the caller pointing at the wrong aux entry.
2266 (add_symbol): If overflowed cur_block, reallocate it larger,
2267 chase all pointers to it, and complain(), rather than clobber memory.
2268 (shrink_block): Use xrealloc rather than xmalloc-and-copy.
2269 (new_field): Only allocate one field initially, not two.
2270 Pull ++ out of macro argument. Simplify.
2271 (_initialize_mipsread): Avoid initialization of importd
2272 global_psymbols and static_psymbols.
2274 * symfile.c (psymtab_to_symtab): Depend on XXX_psymtab_to_symtab
2275 to properly set pst->symtab; avoid searching for it.
2276 (symfile_fns): Improve comments, add a FIXME.
2277 * dbxread.c: Update comments to reflect symfile protocol.
2278 (read_ofile_symtab, end_symtab): Return the symtab.
2279 (psymtab_to_symtab_1): Set pst->symtab.
2281 * coffread.c (coff_symfile_read): tell condense_misc_bunches
2282 whether we're mainline.
2284 * symfile.h (sym_fns): Remove unused sym_discard member.
2285 * coffread.c, mipsread.c, dbxread.c: Remove XXX_symfile_discard.
2287 * mtrace.c (mtrace): Take effect if mallwatch is set, even if
2288 the environment variable is not.
2289 * infcmd.c (finish_command): Use filtered printfs.
2290 * cplus-dem.c: Add struct tags to a few unnamed structs.
2291 * valops.c (value_coerce_array): Improve comments.
2292 * valprint.c (type_print_varspec_suffix): Print array size only
2293 if greater than zero.
2294 * m88k-tdep.c: Shift some lines left by one space, that had
2295 apparently been trashed at some point.
2296 * TODO: More things to do, a few got done.
2298 Thu Jul 18 22:46:05 1991 John Gilmore (gnu at cygint.cygnus.com)
2300 * symtab.h (LOC_EXTERNAL): Eliminate in favor of LOC_STATIC.
2301 (ldsymoff, ldsymlen, globals_offset, statics_offset): Improve
2303 * dbxread.c (read_dbx_symtab): LOC_EXTERNAL -> LOC_STATIC.
2304 * expread.y, findvar.c, symmisc.c: Ditto.
2305 * printcmd.c (address_info): Update printed forms of LOC_
2306 symbols. Elim LOC_EXTERNAL.
2307 (print_frame_args): Keep track of param stack offsets before
2308 re-looking up to find the local register param is kept in.
2310 * mipsread.c: Use <symconst.h> and <sym.h> rather than <syms.h>.
2311 Further integration of mipsread into gdb. Eliminate unused
2312 routines, duplicate declarations. Handle static symbols in
2313 psymtabs as well as external symbols. When reading symtabs,
2314 insert symbols into the correct block (global, static, or a local
2316 (read_mips_symtab, parse_partial_symbols): Don't pass useless
2318 (mipscoff_symfile_read): Don't call select_source_symtab.
2319 (parse_symbol): Use SYMBOL_VALUE_ADDRESS where appropriate,
2320 rather than SYMBOL_VALUE.
2321 (parse_external): Comment clobbering of top_stack.
2322 (parse_partial_symbols): Update comments. Allocate and parse
2323 static symbols as well as external symbols. FIXME, enum values
2324 are not handled in this pass, but should be. Inline new_psymbol.
2325 Use SYMBOL_VALUE_ADDRESS.
2326 (psymtab_to_symtab_1): Read symbols into global static block
2327 by default (until enter some function's local block context).
2328 (sort_blocks): Clean up STATIC_BLOCK as well as GLOBAL_BLOCK.
2329 (destroy_all_symtabs, new_psymbol): Eliminate, unused.
2331 * source.c (select_source_symtab): Select a source symtab
2332 from either the symtabs or, failing that, the psymtabs.
2333 (list_command): Update error message.
2334 (forward_search_command, reverse_search_command): Use getc, not
2335 fgetc, for speed. FIXME, add comment about buffers that die if
2336 overrun by long line.
2338 * values.c (unpack_field_as_long, modify_field): Avoid shifting
2339 by an entire word, which is not portable, if we have a 32-bit
2340 field. (Code in dbxread.c already turns such bitfields, if
2341 aligned, into ordinary ints, but fixing this will help for other
2342 symbol formats and for future changes.)
2343 * core.c (core_open): Handle ANSI const brain death.
2344 * utils.c (vprintf): Fix varargs typo.
2346 Sun Jul 14 00:42:53 1991 John Gilmore (gnu at cygint.cygnus.com)
2348 * findvar.c (find_var_value): Handle &function better.
2349 * TODO: Document work needed on &fn and &array.
2350 * printcmd.c (print_address_symbolic): New arg is the prefix
2351 to print if a name is printed.
2352 (print_address_demangle): Honor "set print address" now.
2353 Use new arg above to improve spacing of output.
2354 * valprint.c (val_print): When printing function pointers,
2355 print symbolic form too.
2356 * breakpoint.c (breakpoint_1): Use new print_address_symbolic.
2358 Mon Jul 8 19:02:46 1991 John Gilmore (gnu at cygint.cygnus.com)
2360 * core.c (memory_error): Reword error msg to mislead less.
2362 * mips-pinsn.c (print_insn_arg 'd'): Print $ with reg name.
2364 * mipsread.c (read_mips_symtab, read_the_mips_symtab,
2365 parse_partial_symbols): Use newer BFD internals (external_filehdr
2366 and external_aouthdr), byte-swap the fields that we care about
2367 before using them, and make the file header data local to
2368 read_the_mips_symtab rather than global.
2370 Sat Jul 6 01:34:15 1991 John Gilmore (gnu at cygint.cygnus.com)
2372 * ns32k-opcode.h (movmw, movmd): Fix opcodes. Bug fix
2373 from Rune Nerg}rd <runene@ifi.uio.no> on 5 Jul 1991.
2375 * main.c (command_line_input): Flush stdout and stderr
2376 before every call to readline. This reportedly fixes a bug
2377 that comes up in Sys V running emacs-gdb and/or xxgdb,
2378 when stdin/out are pipes or sockets.
2380 Thu Jul 4 14:47:06 1991 John Gilmore (gnu at cygint.cygnus.com)
2382 * configure.in, Makefile.in: Avoid rebuilding "depend" as much.
2383 Avoid declaring Makefile dependencies, because GNU Make stupidly
2384 tries to update it if we do.
2386 * coffread.c: Revise for minor changes to bfd internal coff
2389 * configure: If -template= is given a relative path, make it
2390 absolute before recurring in subdirectories.
2392 * configure, configure.in, Makefile.in: Install "configure" script
2393 as replacement for config.gdb.
2394 * config.gdb, Makefile.dist, Makefile.sdir: Remove
2395 * README: Update for configure, mostly. FIXME.
2397 * Add dec3100 as equivalent to littlemips. Indicate in all host &
2398 target config files that they are for the host. When the lines
2399 get copied into the Makefile, this makes it more obvious what's
2402 Mon Jun 24 23:49:07 1991 John Gilmore (gnu at cygint.cygnus.com)
2404 * sparc-opcode.h (trap opcodes): Avoid leading spaces or
2405 tabs, which end up in the disassembler output inadvertently.
2407 Wed May 29 23:01:03 1991 John Gilmore (gnu at cygint.cygnus.com)
2409 Make it compile cleanly in an ANSI GCC2 environment.
2411 * blockframe.c: <stdio.h>
2412 * cplus-dem.c: free takes a void *, ifdef __STDC__
2413 * dbxread.c (read_huge_number): avoid gcc2 bug hoisting calc of
2415 * defs.h (alloca): Avoid doing anything if alloca already def'd.
2416 * stddef.h, stdlib.h: Remove these files.
2417 * symtab.c: Avoid declaring qsort, close.
2418 * symfile.c: Avoid declaring close.
2419 * utils.c (vprintf): Declare "ap" arg as proper va_alist.
2420 * sparc-tdep.c: Avoid including lots of Sun-host-specific files.
2422 Assorted other changes.
2423 * dbxread.c: include "libaout.h", not "liba.out.h".
2424 * printcmd.c (print_frame_args): Set recurse properly for
2425 indentation of struct and array parameters.
2426 * valops.c (value_cast): Allow cast to void.
2427 * infrun.c (resume): If NO_SINGLE_STEP, call machine dependent
2428 single_step() in a target-independent fashion.
2429 * sparc-tdep.c (single_step): Don't call ptrace ourselves, just
2430 set up to be ready to continue. This makes us target independent.
2431 * infptrace.c (child_resume): Remove call to single_step; now
2432 can single step a SPARC target of any kind.
2434 Wed May 22 18:18:24 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
2436 * Makefile.dist, doc/gdb.texinfo, doc/*-m4.texinfo: split up GDB
2437 docn into separate sections---basically chapters, plus two loose
2438 pieces that can be configured to go in different places. This
2439 allows GNU m4 to preprocess the manual without coredumping.
2441 * Makefile.dist: tell TeX where to find texinfo.
2443 Mon May 20 12:15:04 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
2445 * Makefile.dist, doc/gdb.texinfo: respectively create, and use,
2446 the new target "rdl-apps.texinfo" which captures the Makefile
2447 variable that records where to find the Readline libraries.
2449 Sun May 19 05:36:59 1991 John Gilmore (gnu at cygint.cygnus.com)
2451 * tahoe-pinsn.c: #include "tahoe-opcode.h", not "opcode.h".
2452 * tm-tahoe.h (FIX_CALL_DUMMY): Ignore more parameters.
2453 * defs.h (const, volatile): Only define if not already defined.
2454 * Makefile.dist (gdb.tar.Z): Create doc subdir w/out CVS/RCS crud.
2456 * README: Update for release 3.95.
2457 * config.gdb: Don't create readline dir in subdir builds.
2458 * main.c: Include with "..." form for non-system include files,
2459 so "gcc -MM" for "make depend" works.
2460 Include readline files with "...h" rather than <readline/...h>.
2461 * mipsread.c: Include "ecoff.h" rather than "intel-coff.h".
2463 * coffread.c: Undo minor damage done by Rich Pixley. Use
2464 different internal and external representations of COFF
2465 data structures. Use new BFD routines for swapping them in and
2467 * symfile.c (free_named_symtabs): Avoid freeing file names that
2468 are null or empty. Old i960 tools seem to produce files that
2469 claim to have empty names, causing each successive file read
2470 to blow away the previous one.
2471 * sparc-xdep.c (deferred_stores): Repair minor damage by Rich.
2472 Move deferred_stores to top of file, but don't separate its
2473 #define's from its variable. Add commentary.
2474 * Makefile.dist: Fix Rich damage; undo "configure" changes in
2475 favor of keeping the (working) config.gdb. Move readline
2478 Fri May 17 12:49:56 1991 Per Bothner (via gnu at cygint.cygnus.com)
2480 * dbxread.c (read_struct_type): Try to handle g++ version 1 MI
2482 * infptrace.c (fetch_registers): no result, since now void.
2483 * tconfig/news: target depends on m68k-tdep too.
2485 Fri May 17 14:40:14 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
2487 * Makefile.dist: added readline/inc-*.texinfo to dependencies for
2490 * readline/inc-history.texinfo, readline/inc-readline.texinfo:
2491 applied various small fixes due to or inspired by RMS comments
2493 * doc/gdb.texinfo: finished using all RMS comments, save those for
2494 appendices on readline and cmd history (which are in other source
2497 Thu May 16 18:06:05 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
2499 * doc/gdb.texinfo: (1) Updated w/ref to RMS comments through
2500 chapter 9; (2) documented 'break' command's menu mode for
2501 overloaded names, in response to hgs problem report C++ p-31
2503 Wed May 15 11:02:48 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
2505 * doc/gdb.texinfo: (1) better introductory example; (2) more
2506 consistent use of @code, @samp, @file, @kbd throughout; small
2507 cleanups to first three nodes; (3) new "Contributors" node;
2508 (4) Appendix, Renamed Commands; (5) divert specialized startup
2509 instructions to "Targets" chapter for generic manuals, while
2510 leaving them up front for manuals specific to specialized
2511 environments; (6) apply fixes from RMS comments through chapter 4.
2513 * pretex.m4: modify explanatory text slightly (and redefine
2514 "regexp") to keep GNU m4 from complaining. (It still crashes
2515 later, but one step at a time...)
2517 Wed May 15 10:32:12 1991 John Gilmore (gnu at cygint.cygnus.com)
2519 * readline/readline.c (update_line): Avoid dereferencing a pointer
2520 before comparing it to its bounds. Saber caught this.
2521 (init_terminal_io): Don't set BC from the "pc=" termcap variable,
2522 and only set PC if tgetstr returned non-null. Saber caught this.
2524 Tue May 14 16:29:53 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)
2526 * Makefile.dist: put gdb.dvi stuff (updated to use M4 preprocessor
2527 stuff for config manual) here where it counts; updated
2528 to use new subdir structure (gdb/doc/).
2530 * Makefile: generated from above via
2534 * gdbint.texinfo: added instructions on generating gdb.info* files
2535 locally for release. These are ordinary info
2536 files, formatted from gdb.texinfo (via gdb-all.texinfo, see
2537 Makefile)---but due to use of texinfo 2, can't count on makeinfo
2538 to generate these, so we distribute them already formatted.
2540 * gdb.texinfo: included full Info node and menu crud (as generated
2541 by C-u M-x texinfo-master-menu using the texinfo-2 elisp code).
2543 * Makefile: updated "gdb.dvi" target to use M4 preprocessor;
2544 put in comments-for-future gdb.info target (one day makeinfo will
2547 Tue May 14 13:51:36 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)
2549 * gdb.texinfo: Updated to include new or old undocumented
2550 commands, at least the following (perhaps some others I forgot to
2551 record): info f, info float, info path, info program, info s, info
2552 set, info source, info terminal, info types, info user, set/show
2554 Also covered all recent GDB command renames for v4.
2556 Mon May 13 14:57:46 1991 John Gilmore (gnu at cygint.cygnus.com)
2558 * mipsread.c: Rather than keeping count of how many symtabs
2559 and psymtabs we have, for sorting purposes, count them when
2560 we need to sort. This fixes bug in rereading of symbol tables.
2562 Fri May 10 15:43:33 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)
2564 * infcmd.c: renamed "info path" to "show paths"

2579 symtab.h, target.c, target.h: Lint.
2580 * core.c: setup and select frame after reading shared libs,
2581 else reading shared libs will clobber them. Lint.
2582 * utils.c (error): Force out any buffered wrap text.
2584 Fri May 3 22:01:56 1991 John Gilmore (gnu at cygint.cygnus.com)
2586 * remote.c: Remove decls of memory_insert_breakpoint
2587 and memory_remove_breakpoint, no longer used. (Suggestion of
2590 * Makefile.dist: use ${subdir} in paths of BFD and LIBIBERTY,
2591 to make it easier to interface to "configure"'d libraries.
2593 Fri May 3 13:10:01 PDT 1991 Roland Pesch (pesch at fowanton.cygnus.com)
2595 * valprint.c: introduce "set p", "set pr", "show p" and "show pr" as
2596 aliases for set/show print.

2890 (2, 3) Look in the STATIC_BLOCK for all the symtabs and psymtabs
2893 * main.c (cd_command): Call dont_repeat.

3108 core.c, exec.c, remote-eb.c, remote-nindy.c, remote-vx.c,
3109 remote-vx.68.c, inftarg.c, remote.c: Add doc field to target struct.

3139 command is add-symbols.
3140 * target.c (dummy_target): Permit add_syms_addr_command.
3142 Sat Apr 13 14:46:07 1991 John Gilmore (gnu at cygint.cygnus.com)
3144 Permit symbols to be superseded when new symbol files have
3145 been read in, particularly for VxWorks.
3147 * dbxread.c (read_dbx_symtab): Allow N_SOL to cleanly take us back
3148 to the main file, as well as to include files. Also, put global
3149 functions into the global psymtab, to make "i fun" work.
3150 (end_psymtab): Free named symtabs and psymtabs for a file, once a
3151 new psymtab for it has been read.
3152 * coffread.c (end_psymtab): Free named symtabs and psymtabs for
3153 a file, once a new symtab has been read for it.
3154 * mipsread.c: FIXME. We need to do the same for MIPS, but it
3155 looks harder to determine the top-level block before it's been
3156 queued to the psymtab list.
3158 * symfile.c (symbol_file_add): Use filtered printing and wrap it.
3159 If we have wiped out any old symbol tables, clean up at end of
3161 (symbol_file_command): Don't reference symfile_fns if it's zero.
3163 * symtab.h (GLOBAL_BLOCK, STATIC_BLOCK, FIRST_LOCAL_BLOCK): New
3164 defines for the blocks of a blockvector that contain global and
3165 file-static symbols and the first of the smaller scope contours.
3166 * symtab.c (lookup_symbol, find_pc_symtab, find_pc_line,
3167 decode_line_1, make_symbol_completion_list): Use the above.
3168 * coffread.c (end_symtab, patch_opaque_types): Ditto.
3169 * dbxread.c (end_symtab): Ditto.
3170 * expread.y (block): Ditto.
3171 * mipsread.c (throughout): Ditto.
3172 * symmisc.c (free_named_symtabs): Ditto.
3174 * symtab.c (list_symbols): Process the first symbol of the
3175 static psymbols list.
3176 (types_info): Restore this function from its untimely #if 0.
3177 It's not perfect, but it is better than nothing.
3178 (_initialize_symtab): Restore "info types".
3180 Thu Apr 11 05:23:19 1991 John Gilmore (gnu at cygint.cygnus.com)
3182 * m68k-stub.c: Remote stub for 680x0's, created from
3183 rem-m68k.shar (which is removed).
3184 * nindy-share/{Makefile,Onindy.c,blout.h,env.h,nindy.c,ttyflush.c}:
3185 Remove RCS log stuff now that we use CVS and it blows our diffs.
3187 Wed Apr 10 14:18:06 1991 John Gilmore (gnu at cygint.cygnus.com)
3189 * symmisc.c (free_named_symtab): Make it work, in its current
3190 kludgy fashion. Change result to indicate if we blew away bkpts.
3191 * dbxread.c (end_symtab): Accumulate result from
3192 free_named_symtab and print warning if we blew user's state.
3193 * symfile.h: free_named_symtab now returns an int.
3195 Mon Apr 8 23:57:43 1991 John Gilmore (gnu at cygint.cygnus.com)
3197 * dbxread.c (dbx_symfile_read): Initialize psymbol list if this
3198 is the first symbol read, even if not mainline.
3199 (dbx_psymtab_to_symtab): symfile might be zero, cope.
3200 * exec.c (exec_ops): Add_syms_addr is valid in our tvec.
3201 (set_section_command): New command ("section xxx yyy" -- should
3202 be renamed to "set section xxx yyy" FIXME) which sets the
3203 base address of a section of the exec file, overriding the
3204 virtual address that BFD reports.
3206 Fri Apr 5 17:14:39 1991 John Gilmore (gnu at cygint.cygnus.com)
3208 * exec.c: Add add_syms_addr_command to exec_ops, so you can
3209 load symbols at any address while examining an exec file.
3211 Thu Apr 4 10:09:35 1991 John Gilmore (gnu at cygint.cygnus.com)
3213 * tm-i386v.h (FLOAT_INFO): Don't define it, since the code
3214 for printing the float info is host-dependent, not
3215 target-dependent. FIXME.
3216 * i386-pinsn.c: Move #includes to top, remove useless ones.
3217 * i386-tdep.c: Don't bother including <.../reg.h> since we
3218 don't use it (and it doesn't exist on host systems).
3220 * ieee-float.c (ieee_extended_to_double): Convert NaN to Inf.
3221 Convert negative numbers properly.
3222 (ieee_test): Make numbers really random; fix format arg.
3224 * infcmd.c (attach_command, detach_command): Don't repeat on CR.
3225 * core.c (core_detach): Unpush core_ops, which might not be on
3226 top. We used to just pop the top, which broke things. Don't
3227 need dont_repeat() any more.
3228 (core_file_command): Psst! Don't repeat it.
3229 * remote-nindy.c (nindy_detach): Don't need dont_repeat() now.
3230 * expprint.c (print_subexp): Avoid switch fallthru on
3231 BINOP_ASSIGN_MODIFY, so we can print += and such.
3232 * frame.h: Fix typo.
3233 * inflow.c (kill_command): After killing inferior, print our
3234 current frame in the core file, if we have one.
3235 (generic_mourn_inferior): When inferior dies, either select
3236 the current frame (in the new target, e.g. core file), or
3237 set both the current and selected frames to NULL.
3239 Changes from Peter Schauer.
3241 * infptrace.c: Avoid <sys/ptrace.h> on USG.
3243 * Make all file names fit in 14 characters (sigh and damn!):
3244 mv hp300hpux-xdep.c hp300ux-xdep.c
3245 mv symmetry-xdep.c symm-xdep.c
3246 mv symmetry-tdep.c symm-tdep.c
3247 mv convex-opcode.h convx-opcode.h
3248 mv tm-vxworks960.h tm-vx960.h
3249 mv tm-vxworks68.h tm-vx68.h
3250 mv Makefile.srcdir Makefile.sdir
3251 mv gdb-int.texinfo gdbint.texinfo
3252 mv remote-sa.m68k.shar rem-m68k.shar
3253 mv remote-multi.shar rem-multi.shar
3254 * Makefile.dist, README, config.gdb, convex-pinsn.c,
3255 tconfig/symmetry, tconfig/vxworks960, tconfig/vxworks68,
3256 xconfig/hp300hpux, xconfig/symmetry: Change names to shorter
3259 * command.c (user_info_1, user_info): New command for listing
3260 the user-defined commands.
3262 Wed Apr 3 15:00:26 1991 John Gilmore (gnu at cygint.cygnus.com)
3264 * dbxread.c (really_free_pendings): Clear file_symbols
3265 and global_symbols after freeing them; otherwise, running
3266 this function twice (if it appears twice on the cleanup
3267 chain), we try to free things twice.
3269 * dbxread.c (read_dbx_symtab): Calculate end_of_text_addr
3270 based on text_addr (the address of text in core), not on addr (the
3271 offset between text in the .o file and in core). This change
3272 is from Peter Schauer.
3274 * main.c: Define ALL_CLEANUPS as a cast of zero.
3275 (return_to_top_level): Use it.
3276 (main): Do all cleanups after each command run as part
3277 of the gdb startup sequence. Also do all cleanups before
3278 entering the command loop, and every time we exit the command
3279 loop and reenter. Before, the cleanups from the startup sequence
3280 were being left undone until the first error!
3281 (command_loop): Rename do_nothing cleanup to command_loop_marker
3282 so we can see it easily when examining the cleanup chain.
3283 (init_signals): Add another do_nothing for signal handling.
3284 (quit_command): Only try to kill target if it has execution.
3285 Problems in the target stack got us into a state where
3286 inferior_pid was nonzero but none of the targets had execution.
3287 In this state you couldn't exit gdb.
3289 * dbxread.c: Two changes from Peter Schauer.
3290 (echo_command): Fflush output after an echo command.
3291 (show_history): Pass all args to cmd_show_list.
3293 * utils.c (init_malloc): Call mtrace to turn on tracing
3294 if the environment variable MALLOC_TRACE is set to a file name.
3295 * mtrace.c: Add source file which provides a log of every malloc,
3296 free, and realloc to a trace file.
3297 * mtrace.awk: Add source file which analyzes the trace file.
3298 * Makefile.dist (GNU_MALLOC, MALLOCSRC): Add mtrace.{c,o,awk}.
3299 (VERSION): Roll to 3.94.3.
3301 * breakpoint.c (breakpoint_1): Add a space to "i watch" output.
3302 (check_duplicates): Don't bother with watchpoints.
3303 (set_raw_breakpoint): Comment about danger of this routine.
3304 (watch_command): Parse and eval all args before calling
3307 * solib.c (find_solib): Avoid error in referencing memory to
3308 see if any more shared libraries have been added. This is
3309 particularly useful if the target has terminated. Bug reported
3312 Changes from Peter Schauer <pesrem@regent.e-technik.tu-muenchen.de>
3313 in bringing up 3.94.2 on the Sun-3.
3315 * Makefile.dist: Include CFLAGS in rule for cplus-dem.o.
3316 * breakpoint.c (enable_breakpoint): Check for valid watchpoint
3317 expression (in scope) before reenabling watchpoint.
3318 * signame.c (init_sigs): Add missing declaration of i, fix
3319 sys_siglist declaration.
3320 * source.c (list_command): Fixed range computation to use
3322 * stack.c (backtrace_command): Do not allow command if target has
3323 no stack, print informative error message.
3324 * target.c (target_command): Do not write into command line
3325 because this fails if the target command is used in a user defined
3326 command. [This change was enhanced by gnu to support any-
3327 unique-prefix matching on target names.]
3328 * valops.c (value_struct_elt): Avoid infinite loop on an
3329 erroneous attempt to print the member of function (try p main.p).
3331 Mon Apr 1 17:05:45 1991 John Gilmore (gnu at cygint.cygnus.com)
3333 * expread.y (name_no_typename): Avoid reduce/reduce errors
3334 caused by ambiguity in handling NAME_OR_INT and NAME_OR_UINT.
3335 Since the GDB parser really doesn't use name_no_typename in a
3336 name-only context, the parser can't tell the diff between
3337 names and numbers here. Avoid allowing a name_no_typename
3338 to be a NAME_OR_*INT to resolve the conflict.
3340 Sun Mar 31 20:12:07 1991 John Gilmore (gnu at cygint.cygnus.com)
3342 Bugfixes from Mark Fox (markf@wrs.com) (test=testField.c):
3344 * valprint.c (val_print_fields): bitfield printing didn't handle
3345 byte order. Indirect through a few more fns to cope.
3347 * values.c (modify_field): also cope with byte order.
3349 Sat Mar 23 10:02:21 1991 John Gilmore (gnu at cygint.cygnus.com)
3351 Cleanup for release 3.94.2:
3353 * Makefile.dist: Pull REMOTE_OBS. Fix saber includes for BFD
3354 include files. Roll version to 3.94.2.
3356 * coffread.c (init_stringtab): Read length into unsigned char
3357 array before swapping; don't assume 32-bit longs.
3359 * target.c (target_info): Don't bother with get_sym_file, just use
3360 the symfile global variable.
3361 * symtab.h, symfile.c (get_sym_file): Delete it.
3363 * dbxread.c (dbx_symfile_init): Don't depend on long == 4 bytes.
3364 (define_symbol): Set symbol line number to 0 if not gcc-compiled.
3365 (read_type): Replace one more error() with complain().
3367 * mipsread.c (parse_partial_symbols): Replace printf with complain.
3369 * i960-tdep.c: Fix copyright attribution.
3371 * config.gdb: Quote all backquotes in doublequotes. You can
3372 quote me on that. BSD 4.4 shell found this one.
3374 * infptrace.c (throughout): The third argument to ptrace is an
3377 * infrun.c (wait_for_inferior): When program has terminated, we
3378 have to call target_terminal_ours before we pop that target off
3379 the stack (e.g. before a call to target_kill or
3380 target_mourn_inferior). This fixes problem where a program
3381 terminates, then GDB stops for (tty output) and you have to type
3382 "fg" to the shell to resume it. FIXME: This code for what to
3383 do after termination really should be in normal_stop instead.
3385 * gdbcore.h (read_memory_check): Change declaration; it changed
3388 * terminal.h: Include <sgtty.h> before <sys/ioctl.h>, since in BSD
3389 4.4 prereleases, this avoids a bug in their sgtty compatability
3391 * remote.c: Use terminal.h rather than hand-rolling the same.
3393 * signame.c, signame.h (psignal): Arg is unsigned, not int.
3394 * utils.c (strsave, strstr): Fix arg types.
3395 * valprint.c (val_print): lint
3397 MIPS symbol table support from Per Bothner:
3399 * symfile.c (symtab_fns): Remove initializer table that needs to
3400 be hacked for each new symbol file format supported.
3401 (add_symtab_fns): New function, chains symbol table
3402 handlers into the global list.
3403 (symfile_init): Search this list.
3404 * symfile.h: Add next pointer, declare add_symtab_fns.
3405 * coffread.c (_initialize_coffread): Call add_symtab_fns.
3406 * dbxread.c (_initialize_dbxread): Call add_symtab_fns.
3408 * mipsread.c (psymtab_to_symtab_1): return void instead of (struct
3409 symbol *). Thus, we no longer need the hack to trash
3410 pst->filename. Good, since that hack confused code in symfile.c!
3412 (reorder_symtabs, destroy_all_symtabs): Removed static
3413 all_symtabs, which was used to qsort symtabs in reorder_symtabs.
3414 Instead, the latter now uses a temporary array (stack-allocated
3415 from an obstack, and then freed).
3417 (parse_symbol): Added a hack to fix up BLOCK_{START,END} if they
3418 haven't been set in the outermost stBlock of a procedure. This was
3419 a problem with f77 binaries on Ultrix 4.?.
3421 (new_symtab, new_symbol, new_type): Continue changing code to use
3422 obstacks more and otherwise conform to dbxread internal style.
3423 Made the free_code of symtabs be free_linetable (as in dbxread)
3424 instead of free_contents. This implies memory leaks when reading
3425 a new symbol table, until the conversion is finished. Did change
3426 (struct symbol) and (struct type) to be allocated on the
3427 symbol_obstack. Blocks and blockvectors are among the things
3430 * mipsread.c (parse_partial_symbols, parse_fdr): It hasn't been
3431 tested much, but it solved one problem (reported by Meissner), and
3432 cleans up some other things. The problem happened when an
3433 included file contains actual code (functions) and not just
3434 definitions. The mips coff is a little inconvenient there, since
3435 it may cause a procedure to be mapped to the wrong psymtab.
3437 * mips-tdep.c (heuristic_proc_desc): Minor cleanup.
3438 * mips-xdep.c (fetch_core_registers): Minor cleanup. FIXME,
3439 this will need work for the new core paradigm.
3441 Opcode patches from the net:
3443 * mips-opcode.h: fix incorrect disassembly of the mfc1, cfc1, and
3444 ctc1 instructions. Also, the cvt.d.w and cvt.s.w instructions were
3445 missing altogether - they are added here. From Bruce Bauman.
3446 * mips-opcode.h: The low mask for C0 instructions was too small.
3447 From Garrett Lau. I modified the fix to check the entire 32-bit
3450 * ns32k-opcode.h: Fix opcodes for deiw and deid. From Bruce
3453 Thu Mar 21 12:56:46 1991 John Gilmore (gnu at cygint.cygnus.com)
3455 Roll in changes from Per Bothner (Tue, 25 Sep 90 11:11:04):
3457 * dbxread.c (read_type): Pointer subtraction (value_sub in
3458 valarith.c) sometimes failed because the types of the
3459 pointers being subtracted were not identical.
3460 These differed because dbxread.c was allocating pointer types
3461 using dbx_alloc_type+smash_to_pointer_type instead of
3462 lookup_pointer_type. I failed to find a justification for the
3463 former, so I changed it to use the latter. Similarly, I
3464 replaced smash_to_function_type by lookup_function_type,
3465 and smash_to_reference_type by lookup_reference_type.
3467 * mipsread.c (parse_symbol, upgrade_type, parse_procedure,
3468 _initialize_mipsread): corresponding changes.
3470 * symtab.c (smash_to_{pointer,reference,function}_type): eliminate.
3472 * source.c (mod_path): Do tilde_expand on each component of the path,
3473 rather than on the (list of) paths as a whole.
3474 (print_source_lines): Set first_line_listed in addition to
3475 current_source_symtab and current_source_line. If the source was
3476 not findable, after a "dir" command to fix the problem,
3477 a "list" would get the wrong lines.
3479 While I was there... (gnu):
3481 * dbxread.c (read_type): Change error to complaint.
3483 Thu Mar 21 12:56:46 1991 John Gilmore (gnu at cygint.cygnus.com)
3485 First attempt at detailed understanding of symbol table memory alloc.
3487 * dbxread.c (dbx_symfile_read): Free our string table if we
3488 aren't the mainline. Free the "info" struct since we're done with
3490 (init_psymbol_list): Free any previously allocated psymbol lists.
3491 (): FIXME: Should realloc-down the psymbol lists when done reading
3492 the main symbol file?
3494 * symmisc.c (free_symtab): Free fullname field too.
3496 * xm-hp300hpux.h (USG): #undef then #define so Makefile can -D.
3497 (REGISTER_ADDR): Make result type unsigned int.
3499 * xconfig/{i386*,hp300hpux,altosgas,altos}: All config files that
3500 define REGEX must also define REGEX1 (its dependency).
3502 Tue Mar 19 21:28:57 1991 John Gilmore (gnu at cygint.cygnus.com)
3504 * tconfig/i960: No longer works, points you at vxworks960 or
3507 * xgdb.c, XGDB-README: Remove file. Users can get the much
3509 * Makefile.dist: Remove all trace of xgdb.
3511 * breakpoint.c (breakpoint_1): Pass demangle arg to
3512 print_address_symbolic.
3513 (clear_breakpoints): Remove unused function.
3514 (breakpoint_re_set_one): Guts of breakpoint_re_set.
3515 (breakpoint_re_set): Use catch_errors to do them all anyway.
3517 * gdb-int.texinfo (Host versus Target): Add section on what is
3518 a "host" feature versus what is a "target" feature.
3520 * infcmd.c (path_command, path_info): Handle the PATH variable
3521 (object search path) as conveniently as the source search path.
3522 * environ.c (set_in_environ): Set some vars in GDB's environment,
3523 in addition to the child's. PATH, G960BASE, G960BIN for starters.
3524 * source.c (mod_path): New function, from guts of
3525 directory_command, modifies a path. Used by path_command.
3526 (directory_command): Call it.
3527 * defs.h (strsave): Declare.
3529 * utils.c (sevenbit_strings): Add new printing option.
3530 (printchar): Use it.
3531 (strsave): Provide this handy helper routine.
3532 (set_width_command): Rename set_screen_width_command.
3533 (_initialize_utils): "set screen-width" => "set width";
3534 "set screen-height" => "set height"; add sevenbit-strings.
3536 * infcmd.c (do_registers_info): Print floating point registers
3537 in raw hex as well as float format, regardless of whether it is
3538 a "virtual" convertible register.
3539 * tm-sparc.h (PRINT_REGISTER_HOOK): Print every pair of float
3540 regs as a double, just in case it's being used that way.
3541 * values.c (unpack_long): Comment on array/function coercion.
3542 (unpack_double): Argument is in target byte order now. For
3543 integer arguments, just call unpack_long and float the result.
3544 * m68k-tdep.c: include defs.h for "const" handling.
3545 * remote-nindy.c: Use ieee-float stuff.
3546 (nindy_fetch_registers): Unpack double regs to host double, then
3548 (nindy_store_registers): Pack extendeds to host double, flip
3549 around by misusing unpack_double, send as target double.
3551 * tm-vxworks68.h (FRAME_CHAIN): Handle current frame pointer of
3552 zero, as when stopped at the first instruction of a process.
3554 * blockframe.c: Fix filename in comment (param.h => tm.h).
3555 * sparc-tdep.c (skip_prologue): More explicit nudging comments.
3556 * tm-68k.h: Fix typos.
3558 Fri Mar 15 01:09:34 1991 John Gilmore (gnu at cygint.cygnus.com)
3560 Changes from a bringup on the DEC Vax under Ultrix 4.0.
3562 * coredep.c (fetch_core_registers): Pass end-address of register
3563 section to register_addr as expected. Don't call supply_register
3564 if we'd just pass it garbage.
3566 * dbxread.c (read_dbx_symtab): Skip N_NSYMS on Ultrix.
3568 * exec.c (xfer_memory): Use boolean xfer_fn result, not int.
3570 * target.c (push_target, target_info): Cast enums to int for < or
3573 * stack.c (print_frame_info): Identify source file & line
3574 even if we can't print it.
3576 * xm-vax.h (MISSING_VPRINTF): No longer missing in Ultrix V4.0.
3578 Sat Mar 9 10:08:20 1991 John Gilmore (gnu at cygint.cygnus.com)
3580 Clean up IEEE floating point support.
3582 * ieee-float.h: New file.
3583 * ieee-float.c: Write real routines to convert between host
3584 doubles and various target IEEE extendeds.
3585 * m68k-xdep.c: Eliminate assembler code for extended floats.
3586 * xconfig/{3b1,altos,altosgas,hp300bsd,isi,news,news1000,sun2os3,
3587 sun2os4,sun3,sun3os3,sun3os4}: Eliminate use of m68k-xdep.o.
3588 * tm-i960.h, tm-68k.h (REGISTER_CONVERT_TO_VIRTUAL,
3589 REGISTER_CONVERT_TO_RAW): Use ieee_extended_to_double and
3590 double_to_ieee_extended.
3591 * i960-tdep.c: Define ext_format_i960.
3592 * m68k-tdep.c: Define ext_format_68881.
3593 * sparc-tdep.c: Define ext_format_sparc, though unused.
3594 * Makefile.dist (HFILES): Add ieee-float.h.
3595 * inftarg.c: #include "ieee-float.h" for the REGISTER_CONVERT
3598 Obsolete the "coffstrip" program in favor of using BFD's strip.
3600 * nindy-share/coffstrip.c: Remove file.
3601 * nindy-share/nindy.c (coffstrip): Routine to run bfd_strip.
3602 * Makefile.dist: Remove references to nindy-share/coffstrip.c.
3603 * tconfig/nindy960: Remove reference to coffstrip.o.
3605 * Makefile.dist: Roll version number to 3.94.1 (not yet final).
3607 Wed Mar 6 09:56:45 1991 John Gilmore (gnu at cygint.cygnus.com)
3609 * symfile.h: Add symfile_bfd, common between dbxread and coffread.
3610 * dbxread.c: Remove static symfile_bfd.
3611 * infcmd.c (do_registers_info): Add PRINT_REGISTER_HOOK, though
3613 * inftarg.c (child_detach): Pop the child_ops vector if the
3614 detach is successful.
3615 * remote-nindy.c (nindy_create_inferior): Don't push a new
3616 nindy_ops since nindy uses the same one for execution and memory
3618 * core.c (core_ops): Use child_attach and child_create_inferior
3619 rather than default attach and create_inferior functions.
3621 Handle floating point registers in core files.
3623 * sparc-xdep.c (fetch_core_registers): Rewrite for float support.
3624 * sun3-xdep.c (fetch_core_registers): Rewrite for float support.
3625 This version untested since BFD doesn't yet support sun3 core
3627 * hp300hpux-xdep.c: Rewrite fetch_core_registers to new calling
3628 conventions. Fix comments and style. This version has not
3629 been compiled yet, since we have no HP inhouse.
3630 * core.c (get_core_registers): Look for two sections, ".reg"
3631 and ".reg2", and pass both to fetch_core_registers sequentially.
3633 Revise directory path yet again.
3635 * source.c (forget_cached_source_info): Not static any more.
3636 (init_source_path): New default source path is "$cdir:$cwd".
3637 (dir_command): Handle variable arguments ($cdir, $cwd).
3638 (source_info): Print "Compilation directory" rather than
3639 "Originally compiled in" to remind people of $cdir.
3640 (openp): If the path contains $cwd, use current directory.
3641 (open_source_file): If compilation directory is known, replace
3642 first $cdir in path with the compilation directory.
3643 (print_source_lines): Even if we can't print the lines, set the
3644 current symtab and line for future commands like "info source" or
3645 "breakpoint". Also, error message now contains the file name,
3646 line number, and file access error message.
3647 (_initialize_source): Fix help text to describe changes.
3648 * main.c (cd_command): Forget cached source info when we chdir.
3649 * utils.c (strstr): Add simple implementation.
3651 Tue Mar 5 01:41:40 1991 John Gilmore (gnu at fowanton.cygnus.com)
3653 * coffread.c (read_one_sym, init_linetable, init_stringtab):
3654 Byte-swap COFF symbol tables if necessary when reading them in.
3655 Use complain() to replace error message in one spot. Needs
3656 corresponding change in bfd/coff-code.h to make some symbol
3657 swapping routines non-static.
3659 Mon Mar 4 00:53:40 1991 John Gilmore (gnu at cygint.cygnus.com)
3661 Merge changes from Eirik Fuller, for UTek.
3663 * defs.h (errno): Add declaration.
3664 * altos-xdep.c, arm-xdep.c, convex-xdep.c, gould-xdep.c,
3665 hp300hpux-xdep.c, infrun.c, inflow.c, infptrace.c, i386-tdep.c,
3666 i386-xdep.c, pyr-xdep.c, mips-xdep.c, remote-eb.c, remote-nindy.c,
3667 remote-vx.c, source.c, standalone.c, stuff.c, sun386-xdep.c,
3668 symmetry-tdep.c, symmetry-xdep.c, umax-xdep.c, utils.c: Eliminate
3669 declarations of errno.
3671 * remote-eb.c: Define B19200 and B38400 as EXTA and EXTB.
3673 * remote-vx.c: Include <sys/time.h> for UTek; Sun gets it via
3674 <rpc/rpc.h> and <rpc/types.h>.
3676 Sat Mar 2 15:47:55 1991 John Gilmore (gnu at cygint.cygnus.com)
3678 * i960-tdep.c (examine_prologue): Add new argument limit,
3679 which stops the scan at the end of the prologue, or at the PC.
3680 This fixes a problem where it walks down into the code for the
3681 user's statements if that code looks like function prologues.
3682 Mark Fox and I have been bouncing this code back and forth, making
3683 small changes to it. Callers changed to match.
3685 Tue Feb 26 01:47:07 1991 Cygnus John Gilmore (cygnus at yuba)
3687 Cleanup for gdb-3.94 release final:
3689 * Makefile.dist: Remove remote-vx.c, remote-nindy.c, and all
3690 the .c files from vx-share and nindy-share, from the various
3691 macros, since they are not found via ALLDEPFILES.
3692 (SFILES): Add tm-i960.h.
3693 (alldeps.mak rule): Break out ALLDEPFILES_MAINDIR and
3694 ALLDEPFILES_SUBDIR. List all the nindy and vxworks subdir files
3696 (TAGFILES_MAINDIR): Change ALLDEPFILES to ALLDEPFILES_MAINDIR.
3697 (gdb.tar.Z): Use ALLDEPFILES_SUBDIR as well as SFILES_SUBDIR.
3699 Mon Feb 25 16:02:35 1991 Cygnus John Gilmore (cygnus at oldman)
3701 * am29k-tdep.c: Add contribution line.
3702 (examine_prologue): Cache information about function prologues in
3703 the misc-function-vector to avoid lots of references over the
3704 serial line while examining instructions.
3706 * core.c (core_close): New function made from cleanup_core.
3708 * core.c, exec.c, inftarg.c, remote-eb.c, remote-nindy.c,
3709 remote-vx.c, remote.c, target.c, target.h,
3710 Update target_ops vector to add attach, close, and load entries.
3711 Use add_syms_addr_command, not add_file_addr_command, for
3712 add_file. Break out close routine from existing code.
3714 * dbxread.c (really_free_pendings): Don't free pending_blocks;
3715 they are in an obstack.
3716 (read_dbx_symtab): Relocate end_of_text_addr in the psymtab.
3718 (define_symbol): Add symbol type parameter; change callers;
3719 pass type parameter to DBX_PARM_SYMBOL_CLASS macro to allow
3720 it to influence the symbol class on the i960.
3721 (define_symbol): Swap LOC_CONST's into target byte order.
3723 * exec.c (exec_close): New function.
3724 (exec_file_command): Call it.
3726 * findvar.c (read_relative_register_raw_bytes): Doc byte order,
3727 Fix byte order of frame pointer.
3728 (read_var_value): Result of 0 if var's value can't be found,
3729 e.g. missing FRAME_ARGS_ADDRESS. Byte-swap LOC_CONST and
3730 LOC_LABEL values to target order. Add LOC_LOCAL_ARG.
3731 (locate_var_value): Use read_var_value and use its lazy address
3732 as the location of the var's value. Lint.
3734 * i960-pinsn.c (next_insn): Add routine from vxgdb for scanning
3737 * i960-tdep.c (arg_address, i960_frame_find_saved_regs): Remove
3738 obsolete Intel versions in favor of vxgdb versions.
3739 (check_host, byteswap, byteswap_val, reorder_val): Eliminate
3740 code dealing with byte order of values, which Intel did in host byte
3741 order rather than gdb-4's target byte order.
3742 (i960_frame_chain_valid): Move to nindy-tdep.c.
3743 (examine_prologue, skip_prologue, frame_find_saved_regs,
3744 frame_args_address, leafproc_return, saved_pc_after_call,
3745 pop_frame): Add vxgdb versions from Mark Fox.
3746 (examine_prologue, frame_struct_result_address): Add code
3747 to deal with the saved value of G13 (struct return address
3749 (frame_args_address): Modify Mark's version to prefer the
3750 saved value over the current value in the topmost frame.
3751 Cache result in the frame info to avoid performance hair in
3753 (print_fault): Add gdb960 code for printing faults.
3754 (_initialize_i960): Actually call check_host.
3756 * ieee-float.c (ieee_extended_to_double, ieee_double_to_extended):
3757 add stub routines. FIXME, these currently just return zero!
3759 * infcmd.c (program_info): Use PRINT_RANDOM_SIGNAL.
3760 (attach_command): Call target_attach, not target_open, now.
3762 * infrun.c (normal_stop): Make global, not static, for vx_attach.
3763 (child_attach): Rename from child_open.
3764 (wait_for_inferior): Use PRINT_RANDOM_SIGNAL. If stop_pc is zero,
3765 don't confuse it with a zero step_resume_break_address.
3767 * inftarg.c (child_detach): Eliminate inferior_pid test.
3768 (child_files_info): Clean up message a bit.
3769 (child_ops): Use child_attach, not child_open, to attach.
3771 * mem-break.c: #ifdef out the whole file if BREAKPOINT is not
3772 set (e.g. on VxWorks or NINDY). Move read_memory_nobpt from
3773 findvar.c to here, since it depends on the contents of the
3774 shadow_contents of breakpoints, but keep if #if 0 since it is
3777 * nindy-tdep.c: New file, contains nindy_frame_chain_valid, moved
3780 * printcmd.c (address_info): Handle LOC_LOCAL_ARG. Lint.
3781 (ptype_command, display_command): Eliminate have_inferior_p and
3782 have_core_file_p in favor of target_has_stack or
3783 target_has_execution.
3784 (print_frame_args): Handle LOC_LOCAL_ARG. Eliminate duplicate
3785 code for actually finding the values of arguments, though we still
3786 keep track of the maximum stack offset for use in printing unnamed
3787 arguments. Handle missing FRAME_ARGS_ADDRESS.
3789 * remote-nindy.c (i960_print_fault): Move to i960-tdep.c.
3790 (struct nindy_regs): Define registers passed to/from nindy.
3791 (nindy_fetch_registers, nindy_store-registers): Translate between
3792 nindy and GDB formats for the registers.
3793 (dcache_init): Statically allocate the cache, since it was being
3794 allocated by a malloc that was never freed anyway.
3795 (nindy_create_inferior): Error, not core dump, if no exec file.
3796 (nindy_before_main_loop): Use target_load, not target_add_file.
3798 * remote-vx.c (net_load): Specify large timeout for load
3799 requests. Allow user to break out with INTERRUPT.
3800 (net_break): Remove useless code, clean up. Change callers.
3801 (parse-args, skip_white_space, find_white_space): Clean up arg
3802 parsing to cope with quoted strings.
3803 (net_wait, net_quit): Never call error, just return status.
3804 (vx_read_register, vx_write_register): Cleanup status checking.
3805 #ifdef the code based on which CPU we are using (960 or 68k),
3806 FIXME, this should be completely general but it isn't yet.
3807 (vx_xfer_memory, vx_resume): Cleanup status checking.
3808 (vx_run_files_info): Improve message.
3809 (vx_load_command): Renamed from vx_add_file_command. Allow load
3811 (net_ptrace): Remove unused routine.
3812 (vx_wait): Adopt code from vxgdb960 to cope with broken
3813 connections to target machine and prompt to disconnect. Remove
3814 debug printouts. Map some EVENT_'s to SIGnals.
3815 (add_symbol_stub, vx_open): Print names of object files we found,
3816 and "ok" if we read their symbols OK. Clarify output in general.
3817 (vx_attach, vx_detach, vx_kill): Add these commands.
3818 (vx_convert_from_virtual, vx_convert_to_virtual): Simplify.
3819 (vx_run_ops): Turn off all_mem, to avoid spurious msg in the
3820 "info files" output, and create_inferior, since we already have
3823 * stack.c (frame_info): Replace Frame_unknown with 0.
3824 (print_frame_arg_vars): Handle LOC_LOCAL_ARG.
3825 (return_command): Pop until the PC matches as well as the FP,
3826 so it works even if the FP is shared with another function,
3827 as in "frameless" or "leaf" procedures.
3829 * symfile.c (load_command): renamed from add_file_target_command.
3830 (add_syms_addr_command): renamed from add_file_addr_command.
3831 (add_syms_command): Stub to call target_add_syms.
3832 (_initialize_symfile): Change command names and descriptions,
3833 add-file => add-syms, and load from alias to its own command.
3835 * target.c (kill_or_be_killed, maybe_kill_then_attach,
3836 maybe_kill_then_create_inferior): Default for attempts to start
3837 a process, if one is already running, is to ask about killing
3838 it and retry if yes.
3839 (upstack_create_inferior): #if-0 it, strata obsolete it.
3840 (push_target, unpush_target, pop_target): to_close() a target
3841 before unstacking it.
3842 (target_info): Renamed from target_files_info.
3843 (_initialize_targets): Rename "i files" as "i target", accessible
3846 * target.h: Improve comments about the target_ vectored routines.
3848 * tm-i960.h: Remove NINDY-specific stuff to tm-nindy960.h.
3849 Convert commenting style to standard GNU style.
3850 (DBX_PARM_SYMBOL_CLASS): allow LOC_LOCAL_ARG's to be recognized.
3851 (SKIP_PROLOGUE): No longer a no-op.
3852 (SAVED_PC_AFTER_CALL): Now handles leaf procedures.
3853 (*_REGNUM): Sort register numbers.
3854 (REGISTER_BYTES, REGISTER_BYTE, REGISTER_RAW_SIZE,
3855 MAX_REGISTER_RAW_SIZE, REGISTER_CONVERTIBLE,
3856 REGISTER_CONVERT_TO_VIRTUAL, REGISTER_CONVERT_TO_RAW): Float regs
3857 are now 10 byte extendeds, not 8 byte doubles.
3858 (FRAME_CHAIN_VALID): Make this config-dependent, since it differs
3859 for nindy versus vxworks targets. FIXME, this should possibly go
3860 in the target vector.
3861 (EXTRA_FRAME_INFO, INIT_EXTRA_FRAME_INFO): Cache both
3862 frame_saved_regs and arg pointer with each frame.
3863 (FRAMELESS_FUNCTION_INVOCATION): New leafproc support.
3864 (FRAME_ARGS_ADDRESS): Use cached result.
3865 (FRAME_ARGS_ADDRESS_CORRECT): New, avoids g14 guessing.
3866 (FRAME_FIND_SAVED_REGS): Change arg to subsidiary fn.
3867 (PRINT_RAMDON_SIGNAL): Call print_fault.
3868 (POP_FRAME): Now works.
3870 * tm-nindy960.h: Break this off tm-i960.h. NINDY-specific
3871 option parsing and startup; STACK_END_ADDR, FRAME_CHAIN_VALID,
3872 BREAKPOINT, and DECR_PC_AFTER_BREAK are here.
3873 (ADDITIONAL_OPTION_HANDLER): use target_load, not
3876 * tm-vxworks960.h: Break this off tm-i960.h. VxGDB specific
3877 startup; DECR_PC_AFTER_BREAK, and FRAME_CHAIN_VALID are here.
3879 * valarith.c (value_subscripted_rvalue): Avoid handling
3880 floats and doubles specially; it gave alignment errors. Lint.
3882 * valops.c (value_of_variable, value_of_this): Error if unknown
3885 * valprint.c (print_floating): Bcopy rather than pointer-deref,
3886 to avoid alignment problems.
3887 (value_print): Handle unknown value address.
3888 (cplus_val_print): Two args are ignored; remove them. Change caller.
3889 (val_print): Use unpack_long rather than pointer-deref.
3892 (unpack_long, unpack_double): Use bcopy rather than pointer-deref
3893 to avoid alignment problems.
3894 (value_being_returned): Error if return value unknown.
3895 (set_return_value): Add bogosity warning, FIXME. *
3897 * TODO: A woman's work is never done.
3899 * Makefile.dist: Distribute REMOTE_OBS into tconfig files.
3900 Separate INCLUDE_CFLAGS for use with lint. Add LINTFILES.
3901 Add ieee-float.o to OBS.
3902 * tconfig/{nindy960,vxworks68,vxworks960}: Include the desired
3903 REMOTE_OBS remote-interface files in the TDEPFILES and TM_FILE.
3904 * tconfig/i960: FIXME. Half-merge, produce warning if config'd.
3906 Changes to generalize the VxWorks RPC protocol slightly, to handle
3907 i960 as well as 68000.
3909 * vx-share/dbgRpcLib.h (VX_SOURCE_STEP): Add.
3910 * vx-share/reg.h: Produce i960 regs #ifdef I80960
3911 * vx-share/xdr_ptrace.c: Skip FPA registers if 960.
3912 * vx-share/xdr_rdb.h: Add SOURCE_STEP struct and xdr decl.
3913 * vx-share/xdr_rdb.c: Add xdr_SOURCE_STEP routine.
3914 * vx-share/xdr_regs.c: Add xdr_regs, xdr_fp_status, xdr_ext_fp
3915 for i960. Change xdr_vectors to xdr_opaques for 68k registers,
3916 so they will move in target byte order rather than network
3917 byte order (happens to be the same).
3919 Mon Feb 25 03:41:44 1991 John Gilmore (gnu at cygint.cygnus.com)
3921 * tm-convex.h (END_OF_TEXT_DEFAULT): Remove #if 0'd block.
3923 Sun Feb 24 00:55:53 1991 John Gilmore (gnu at cygint.cygnus.com)
3926 Add contribution lines to various files, showing where they
3929 * breakpoint.c (break_insn, check_break_insn_size,
3930 read_memory_nobpt): Remove to mem-break.c.
3932 * xm-*.h, param-no-tm.h, tm-29k.h, valprint.c: Change BYTE_ORDER to
3935 * tm-29k.h (STAB_REG_TO_REGNUM): Warn user if symbol table
3936 entry has bad register number. This change is not
3937 tested in this release, FIXME.
3939 * frame.h: Eliminate Frame_unknown in favor of a simple zero.
3942 * value.h: Force value's contents field to be aligned to hold
3943 at least a double or a long long (if supported). This avoids
3944 doing bcopy's in and out of the contents field.
3946 (step_1): Avoid coredump under obscure circumstances when we
3949 * symtab.h (misc_info): Add field to misc function vector for
3950 any kind of cached information the target code desires. AMD
3951 29000 uses this to avoid repeating examine_function_prologue's.
3953 * coffread.c: Lint. Remove static symfile, read_section_header.
3954 core.c (have_core_file_p): Lint: remove.
3955 expprint.c (print_subexp): Lint.
3956 infptrace.c, valops.c, valprint.c: lint.
3958 Roll in changes from vxgdb-5.0.1:
3960 * symtab.h: Comment byte order of each address class. Add
3961 LOC_LOCAL_ARG for frame-relative args (960).
3962 expread.y: Use LOC_LOCAL_ARG where LOC_ARG is used.
3963 symtab.c, symmisc.c: ditto.
3965 * infrun.c (init_wait_for_inferior): Clear stop_signal.
3967 * remote.c (remote_resume): Error if resume with a signal.
3969 * symfile.c (prim_record_misc_function): Clear misc_info.
3970 (fill_in_vptr_fieldno): Check stub type of arg.
3972 * valops.c (value_cast): Avoid looking up names of types whose
3973 name we don't know, to prevent coredump. Sun CC produces typedef
3974 rtx and the name of *rtx is zero...
3976 Mon Feb 18 21:16:25 1991 John Gilmore (gnu at cygint.cygnus.com)
3978 Roll in changes from final AMD 29000 port (Tiemann).
3980 tconfig/am29k: Add COFF_ENCAPSULATE and TARGET=TARGET_AM29K
3981 for ../include/a.out.encap.h. This might not work now that BFD
3982 is separately compiled. Instead, BFD support for encap will have
3983 to translate machine type 29k into the right COFF_MAGIC.
3985 * infcmd.c: Remove references to inferior_pid that aren't used
3986 in actual ptrace calls; use target_has_execution, etc.
3987 (have_inferior_p): Remove function.
3988 (program_info): Print target info rather than "process number";
3989 avoid gratuitous messages unless from_tty.
3990 (run_stack_dummy, finish_command): Set proceed_to_finish.
3991 infrun.c: Remove inferior_pid refs. Decl & init proceed_to_finish.
3992 main.c: Lint. Lose have_inferior_p().
3993 inferior.h (have_inferior_p): Remove, lint.
3994 (proceed_to_finish): Add flag to ask that all regs be saved
3995 by normal_stop, for the few commands that need it, speeding up
3996 serial I/O. Add comments to stop_registers.
3998 * remote-eb.c: Remove newline from breakpoint message we grep
3999 for. Never time out when running the user program.
4003 Wed Feb 13 15:34:40 1991 John Gilmore (gnu at cygint.cygnus.com)
4005 Roll in changes from vxgdb-5.0.1:
4007 * dbxread.c (read_dbx_symtab): If we encounter a "FORTRAN COMMON"
4008 symbol in its raw form, we are processing an unlinked ".o" file.
4009 See if the target environment has assigned it an address, using
4010 target_lookup_symbol (VxWorks does), and enter it into the symtab
4013 * tm-vxworks.h (FRAME_CHAIN, FRAME_CHAIN_VALID): Override usual
4014 68k versions for a simpler version that assumes zero FP at bottom.
4015 Fixes bug of truncated stack reports.
4017 * target.h (target_lookup_symbol): Define this routine's args
4018 and result, finally.
4020 * target.c (nosymbol): Default routine for target_lookup_symbol.
4021 (target_default): Default lookup_symbol and call_function too.
4022 (files_info): Only print has_all_memory warning if a non-dummy
4025 * remote-vx.c (vx_read_register, vx_convert_to_virtual,
4026 vx_convert_from_virtual): If target does not have floating point,
4027 zero register "values", and avoid doing cross-net conversions.
4028 (vx_lookup_symbol): Rename net_lookup_symbol, add to vectors.
4029 (vx_open): Rearrange code that attaches to target and reads
4030 symbols for all loaded modules, to work if some of the modules
4031 are not accessible. Add symbol_stub() and add_symbol_stub()
4032 as callbacks from catch_errors(). Allow connect attempt to be
4033 interrupted painlessly with ^C (FIXME, there are still some bugs
4034 if the interrupt happens during symbol reading.). Print
4035 final message with puts_filtered, since symbol messages are
4040 * main.c (catch_errors): Only print errstring if non-null.
4041 (command_loop): Avoid an ioctl per command to test ISATTY.
4043 * remote-vx.c (net_load): make static; avoid sophomoric msg.
4044 (vx_xfer_memory): Return correct result!
4045 (vx_files_info): Indicate whether target has float or not.
4046 (vx_lookup_symbol): Complain, not error, if target gone.
4047 (vx_open): Print "Connected" msg before disabling immediate-quit.
4048 [FIXME: lookup_symbol and vx_open changes need testing.]
4050 target.c, remote-eb.c, inftarg.c, am29k-opcode.h, target.h,
4051 tm-29k.h, tmm-vxworks68.h, symfile.c, gdb-int.texinfo: Add
4052 contributor lines and update copyrights to 1991.
4054 Changes from an attempted H-PUX host port:
4056 * infptrace.c (PT_ATTACH, PT_DETACH): Handle HP/UX, which
4057 defines PT_ATTACH and PT_DETACH but not PT_KILL.
4058 * remote-eb.c (eb_open): Misplaced endif kills sysv H/PUX.
4059 * remote-vx.c: include <sys/time.h> for HPUX.
4060 * hp300hpux-xdep.c (fetch_core_registers): Rewrite old
4061 "core_file_command" routine to BFD regime. May not work yet.
4063 Attempted port of "gdb-3.4 Van Jacobson xgdb" to modern gdb.
4065 * xgdb.c: Replace X10 version with some VJ version.
4066 (FIXME: Its copyright assignment is not on record.)
4067 * xgdb.c: Update include files to X11R4 (Xaw crud).
4068 (xgdb_display_source, create_text_widget): fix call to
4069 get_filename_and_charpos. Rewack source window stuff for X11R4
4070 (gleaned from include files, and "nm's" of binary libraries, since
4071 I had no doc available).
4072 (append_selection, append_selection_word): Disable with FIXME
4073 since R4 changed interface here.
4074 (create_buttons): Add back the old set of buttons.
4075 (xgdb_create_window): Fix call to XtInitialize (&argc not argc).
4077 * Makefile.dist (xgdb, xgdb-init.c): Update for X11R4 on Suns.
4078 Roll VERSION to 3.94 (not yet final though).
4080 Sat Feb 9 09:46:25 1991 John Gilmore (gnu at cygint.cygnus.com)
4082 * obstack.h (obstack_ptr_grow, obstack_ptr_grow_fast,
4083 obstack_int_grow, obstack_int_grow_fast): Eliminate
4084 cast on left of assignment, which gives MIPS cc fits and is
4087 * sparc-pinsn.c (print_insn): Eliminate 'set' test, subsumed by
4088 F_ALIAS. Use printf, not fprintf, when not passing a file
4090 (compare_opcodes): Check that identical instructions have
4091 identical opcodes, complain otherwise.
4093 * sparc-opcode.h (st %fsr): Fix opcode "lose" mask. This
4094 was reported by Roland McGrath.
4095 (unimp): Only match if exactly zero instruction. (Roland)
4096 (branches and traps): Generate all variations of these
4097 instructions with macros, based on a single call that defines
4098 each condition name and its binary representation.
4099 (set): Turn on alias bit, to avoid test in sparc-pinsn.c.
4101 * valprint.c (val_print_fields): Take, and use, format parameter.
4102 This means that "p/x struct" again prints the elements in the
4103 desired format. Changed callers.
4105 * stack.c (frame_info): Use filtered output, and indicate wrap
4106 points. Remove kludgy formatting designed to avoid line wrap.
4108 * utils.c (wrap_here): If the line is already full (because
4109 we had printed a long indent or long wrapped string), do an
4110 immediate newline-and-indent.
4112 * m68k-pinsn.c (print_insn_arg): Bugfix from
4113 ntmtv!thompson@ames.arc.nasa.gov (Mike Thompson): 'bkpt #0'
4114 instruction is incorrectly disassembled as bkpt #8.
4116 * dbxread.c (end_psymtab): Bugfix from Peter Schauer
4117 <pesrem@regent.e-technik.tu-muenchen.de>: If you want to set a
4118 breakpoint in a *.y file gdb will say Reading in symbols for *.y...
4119 and then will dump core (sometimes). I traced it back to an
4120 uninitialized symfile_name in psymtab_to_symtab.
4121 (const_vol_complaint): Add quotes to message.
4122 (define_symbol): Only believe line number if gcc_compiled.
4123 Avoid allocating symbol if we will not return it.
4125 Add target strata support so that newly established targets go
4126 into their right place in the target stack (e.g. a new exec file
4127 doesn't wipe out the ability to access the running process).
4129 * target.h, core.c, exec.c, inftarg.c, remote-eb.c,
4130 remote-nindy.c, remote-vx.c, remote.c, target.c: Add to_stratum
4131 and initialize it properly in all the targets.
4133 * target.h: Document strata. Change return type of push_target.
4135 * target.c (nomemory): new function for dummy memory access.
4136 (tcomplain): Rename complain, now also used in symfile.c.
4137 (push_target): Push targets within strata. New return value shows
4138 whether new target is on top of stack or not. Always keep dummy
4140 (target_files_info): Ignore dummy target.
4142 * core.c (core_open): Warn user, and skip accessing file, if the
4143 core target is not the topmost target in the stack.
4144 * remote-nindy.c (nindy_create_inferior): Avoid unpush_target, now
4147 * remote-vx.c: Remove vx_prepare_to_store from vxworks memory
4148 target_ops, it doesn't belong there since we have no regs there.
4149 Change name of target from machine => memory to clarify.
4151 Thu Feb 7 16:32:09 1991 John Gilmore (gnu at spiff.cygnus.com)
4153 * Freeze version 3.93 for release.
4155 * Makefile.dist: Handle vx-share and nindy-share subdirs
4156 properly when building gdb.tar.Z.
4158 * symtab.c: lint; add no_symtab_msg to consolidate the messages
4159 printed in various places, so I could change just one copy.
4161 * dbxread.c, coffread.c: Change references to bfd->iostream
4162 to cast to FILE *, now that BFD avoids needing types defined
4163 in other header files.
4165 Tue Feb 5 21:39:35 1991 John Gilmore (gnu at cygint.cygnus.com)
4167 * command.c, dbxread.c, expprint.c, infcmd.c, infptrace.c,
4168 infrun.c, printcmd.c, remote-nindy.c, source.c, sparc-tdep.c,
4169 sparc-xdep.c, symfile.h, symmisc.c, utils.c, valprint.c: Lint
4170 (actually gcc -Wall).
4172 * dbxread.c: Remove first_global_sym, last_global_sym, since
4173 they are never referenced.
4175 * defs.h (baud_rate): Declare.
4176 main.c: Define it, and add the -b option to set it.
4178 * gdb-int.texinfo: Add text on how to define a new host or target
4179 architecture, prompted by Per Bothner's questions about MIPS
4182 * gdb.texinfo: Document "complaints". Change doc of -q since
4183 gdb no longer prints the copyright and blurb if you specify a file
4184 name to be debugged (just like Emacs). Add doc for Nindy-specific
4185 command line flags for specifying target serial port and such.
4186 Update copyright to 1991.
4188 * gdbcore.h: Remove a large mass of now-useless crud, since BFD
4189 has taken over for us the job of ripping up executable files. The
4190 crud caused Per Bothner's port to not compile.
4192 * infrun.c (normal_stop): Avoid printing "Program exited
4193 normally" if we are in batch mode. This allows a GDB which
4194 executes a program on a target system, to behave like a Unix
4195 command (input from stdin, output to stdout, no extraneous
4198 * main.c (main): Allow additional machine-dependent command line
4199 options to be specified with the ADDITIONAL_OPTIONS,
4200 ADDITIONAL_OPTION_CASES, ADDITIONAL_OPTION_HELP, and
4201 ADDITIONAL_OPTION_HANDLER macros. Also allow machine-dependent
4202 processing to occur just before the main loop with
4203 BEFORE_MAIN_LOOP_HOOK.
4204 (main): If a "core file" argument is specified, and it is not a
4205 core file, try it as a process ID to attach.
4206 (symbol_completion_function): Attempt to cope with
4207 "show screen-" TAB, not very successfully. This needs more work,
4209 (batch_file): New function, returns whether we are reading
4210 commands from an interactive tty on stdin, or from somewhere else.
4211 Called by normal_stop since it doesn't get from_tty passed down
4212 to it like many commands do.
4214 * remote-nindy.c: Handle command line options for nindy
4216 (nindy_before_main_loop): Prompt user for tty name if they
4217 don't specify it before getting to the interactive command loop.
4219 * tm-i960.c: Add ADDITIONAL_OPTIONS, etc, to handle -O, -brk,
4220 and -r command line options. Also add hook before main loop
4221 to make it easy to specify a tty.
4223 * TODO: More things to do, one done.
4225 Mon Feb 4 23:57:39 1991 John Gilmore and Mike Tiemann (at cygint.cygnus.com)
4227 * dbxread.c: Make complaint() calls pass pointer, not struct.
4228 Add complaints about badly formatted C++ type information
4229 (const/volatile indicator, and parse errors resulting in
4230 error_type). Fix C++ virtual member fn comment.
4231 (read_struct_type): Avoid bumping pointer if we got a parse
4232 error; this prevents our walking beyond the end of a string.
4233 Terminate loop on null char as well as semicolon.
4234 (process_one_symbol): Fix the LBRAC fix so that it uses the
4235 last previous SLINE, FUN, or SO record's PC address. C++ debug
4236 symbols did not have SLINE records in a useful order compared
4237 to the LBRAC records.
4238 (define_symbol): Handle "catch" records.
4240 * symtab.c (check_stub_type): Added new complain
4241 `stub_noname_complain' and added a consistency check to
4242 keep the debugger from crashing when finishing from an
4243 exception frame. A real fix will be needed later.
4245 Sat Feb 2 10:43:05 1991 John Gilmore (gnu at cygint.cygnus.com)
4247 * infcmd.c (attach_command): Make global.
4249 * Makefile.dist (REMOTE_OBS): Make these compile by default,
4250 but make them easy to comment out. Perhaps later they should
4251 be enabled by what CPU you configure for? FIXME.
4252 (VERSION): Roll to 3.93.
4253 (pinsn.o): Remove rule for obsolete file.
4254 (dbxread.o,coffread.o,mipsread.o): Use ${srcdir} explicitly.
4256 Run down a problem that manifested by printing the wrong function
4257 name in stack traces of read_ofile_symtab. Turned out that the
4258 problem was the SunOS 4.1.1 (and previous) C compiler outputs
4259 the LBRAC symbol with an address in the *data* segment, which
4260 blew our binary search through the blocks.
4262 * dbxread.c: Use the complain() facility consistently to bitch
4263 about problems in the symbol file we are reading.
4264 (finish_block): Add code to check the nesting of the blocks;
4265 complain and Procrust them to fit if wrong.
4266 (make_blockvector): Check the order of the blocks, complain
4267 [but don't cope] if wrong.
4268 (process_one_symbol): ifndef SUN_FIXED_LBRAC_BUG, check LBRAC
4269 symbols to be sure their PC value is greater than the last SLINE
4270 (line number) symbol we've seen, complaining and adopting the
4271 SLINE PC value if wrong.
4273 * symfile.h (struct complaint, complaint_root, complain,
4274 clear_complaints): Add.
4275 * symfile.c (complain, complaint_root, clear_complaints): Add
4276 facility to deal with non-fatal complaints and to regularize their
4278 (symbol_file_add): Clear complaint counters to allow new complaints.
4279 (initialize_symfile): Add 'set complaints' and 'show complaints'.
4281 * dbxread.c (dbx_symfile_read): Remember the address and size
4282 of the string table for the main symbol file, so we won't read it
4284 (dbx_psymtab_to_symtab): Fix the check for main symbol file,
4285 to avoid reading the string table yet again. Lint.
4286 (throughout): Improve filtered output, including word wrap.
4287 (read_range_type): Improve Bothner's fix to handle other types too.
4289 * utils.c: Improve line wrap implementation. Handle unlimited
4290 width by making chars_per_line unsigned.
4291 (puts_filtered): New, easy, function.
4293 * defs.h (puts_filtered): add.
4295 * mipsread.c (compare_symbols, sort_symtab): Remove these fns,
4296 call the identical sort_symtab_syms() in symfile.c instead.
4298 * expread.y: Suggest the `file' command rather than `symbol-file'.
4300 * command.h (enum var_types): Add zinteger for seroable
4302 * command.c (do_setshow_command): Handle var_zinteger. Restructure
4303 nested if's into a switch.
4305 * breakpoint.c (bpstat_print): If bpstat "print" flag is not set,
4306 we did not stop because of a breakpoint (it must have been for
4307 some other reason, like a "stepi"), so don't print anything.
4309 * symtab.c: Include <sys/types.h> all the time. Now that BFD
4310 doesn't include <sys/types.h>, old SunOS's require it for
4313 Sat Feb 2 10:39:15 1991 Per Bothner (bothner@cs.wisc.edu)
4315 A test port of gdb-3.92.6 to the Sony NEWS.
4318 Don't normally link in remote- or vx stuff.
4319 Some of it doesn't compile, and it wastes space for 99% of the users.
4320 Remove reference to no-longer-used HAVE_VPRINTF.
4321 Fixed BFD_DEP typo to BFD_DIR.
4323 Fix cast in arg to bfd_h_getlong.
4324 Make char *prefix be const.
4325 Fix how certain range types are mapped into builtin unsigned int types.
4327 Remove 2 #includes. They cause errors (on Sony, at least),
4328 and aren't needed (they wern't in earlier versions).
4330 print_address_symbolic should never demangle labels
4331 (since it prints *assembler-level* labels).
4333 [This was superseded by the change to printcmd below.]
4336 Add some "volatile" return types to avoid warnings.
4337 If MISSING_VPRINTF add vprintf function and not just macro
4338 (since vprintf is used in printcmd.c).
4340 Unless __GNUC__, use obstack_grow instead of obstack_ptr_grow.
4341 (The latter isn't grokked by some PCC-based compilers.)
4343 [This change is in abeyance, we prefer to fix obstack_ptr_grow.]
4345 Make chunk size of dont_print_obstack 32*4 instead of default 4096.
4346 * nindy-share/coffstrip.c
4347 Added some forward declarations (otherwise, gcc complains
4348 about implicit extern redefined as static).
4350 Sun Jan 20 02:38:19 1991 John Gilmore (gnu at cygint.cygnus.com)
4352 Changes inspired by Per Bothner:
4353 * printcmd.c (print_address_symbolic): Take additional parameter
4354 specifying whether to demangle.
4355 (print_address): Pass in asm_demangle to control demangling.
4356 (print_address_demangle): New fn, takes explicit arg to control
4358 * utils.c: Add new vars demangle and asm_demangle, and let them
4360 (fputs_demangled): If !demangle, just print the argument.
4361 (fprint_symbol): If !demangle, just print raw symbol.
4362 * valprint.c (val_print): Call print_address_demangle rather than
4363 print_address, to cause demangling to depend on the global
4364 rather than assembler-level demangling setting.
4365 * WHATS.NEW, gdb.texinfo: Document.
4367 * main.c (show_command): Show all settings if no arg.
4368 (initialize_main): Make "info set" the same as naked "show".
4369 * command.c (cmd_show_list): Handle prefix commands in the
4370 list, and print the name of the setting as well as its English
4371 description and value.
4373 Allow gdb functions to specify where a line should wrap if it
4374 exceeds the size of a terminal line. Use it to make the output
4376 * utils.c (set_screen_width_command): New fn, mallocs a buffer
4377 of the right size when screen width changes.
4378 (set_screensize_command, screensize_info): Remove #if 0'd fns.
4379 (wrap_here): New fn, indicates a point in the output where we
4380 should wrap the line rather than just letting it overflow at a
4382 (fputs_filtered): Implement wrapping.
4383 (n_spaces): New fn, returns a pointer to N spaces.
4384 (print_spaces_filtered): Use n_spaces.
4385 * defs.h (n_spaces): Declare.
4386 * stack.c (print_frame_info): Wrap with 4-space indent after
4387 fn name and before filename and line number.
4388 * printcmd.c (print_frame_args): Wrap with 4-space indent
4389 before each argument name is printed.
4390 * valprint.c (value_print): Wrap with no indentation before
4392 (val_print_fields): Wrap with indentation relative to nesting
4393 level before each field name.
4394 (val_print): Wrap with nesting indentation before array elements.
4395 * command.c (do_setshow_command): Avoid extra newlines,
4396 wrap with 4-space indent around values printed, end with period.
4397 * WHATS.NEW, gdb.texinfo, gdb-int.texinfo: Document.
4399 * breakpoint.c (breakpoint_1): Implement addressprint for
4400 "info breakpoints" display. Change file name and line number
4401 format to " at file:nnn" rather than " (file line nnn)".
4402 * gdb.texinfo: Document.
4405 Fri Jan 18 07:21:25 1991 John Gilmore (gnu at cygint.cygnus.com)
4407 Frozen for gdb-3.92.6 release.
4409 README, WHATS.NEW: Update for 3.92.6 release.
4411 tconfig/{altos, i386v, i386v32, m88k, umax}: Eliminate
4412 coffread.o from configs since it is now built by default.
4413 tconfig/{3b1, altosgas, arm, convex, hp300bsd, hp300hpux,
4414 i386v-g, i386v32-g, isi, merlin, news, news1000, np1, pn,
4415 pyramid, symmetry, vax, vxworks68}: Eliminate dbxread.o
4416 from configs since it is now built by default.
4418 Makefile.dist: Update for release 3.92.6. Handle files that
4419 have been moved to ../include, ../getopt, or ../bfd. Add
4420 saber.suppress and tests directory. Add config.status to
4421 the release (it will say "none").
4423 coredep.c: Minor formatting fixes.
4425 These changes were made in early December but only checked in now:
4426 * nindy-share/Onindy.c, nindy-share/coffstrip.c,
4427 nindy-share/nindy.c: lint
4428 * nindy-share/nindy.c (ninStopWhy): Don't byteswap the
4429 register values coming back from the target; we store values
4430 in target byte order everywhere.
4432 Wed Jan 16 19:01:37 1991 John Gilmore (gnu at cygint.cygnus.com)
4434 * am29k-opcode.h, am29k-pinsn.c: Add 29050 opcodes.
4436 * valprint.c (cplus_val_print, val_print_fields): New functions,
4437 which print C++ objects. They conspire to avoid printing a
4438 virtual base class more than once, following all the twists and
4439 turns of C++ virtual base rules.
4440 (val_print): Call the above rather than do it by hand.
4442 * symfile.c (symbol_file_add): Only reset symfile_mtime for main
4443 symbol file, not for added files like shared libs. This really
4444 needs to be generalized to a timestamp per file.
4446 * core.c (cleanup_core): Avoid coredump if no core file.
4448 * config.gdb: Accept -host or -target in place of +host or
4451 * coffread.c (find_linenos): Avoid desupported BFD interface
4452 to line numbers. We still read them manually rather than using
4453 BFD's "generic" features.
4455 * gdbrc.tex, threecol.tex: Add GDB reference card and its
4457 Makefile.dist: Add refcard to OTHERS list for creating tar files.
4459 * Makefile.dist: Eliminate use of $< in explicit targets.
4461 * readline/Makefile: Use $< rather than $*.c, which does not
4462 include the VPATH in GNU Make.
4464 * tconfig/i960-bout, tconfig/i960-coff: These are identical
4465 copies of tconfig/i960, added for global configuration
4466 compatability. All i960 versions can read both coff and b.out.
4468 * tm-88k.h: Fix multiline macro that lacked \'s. Remove
4469 COFF_FORMAT and COFF_CHECK_X_ZEROES since these are now handled
4472 * TODO: Think of more things to do.
4474 Wed Jan 2 19:09:29 1991 John Gilmore (gnu at spiff.cygnus.com)
4476 tconfig/{am29k,i960,sun2*,sun3*,sun4*}: Eliminate config
4477 of sdb versus dbx debug symbols. Add kludge for 68881 80-bit to
4478 64-bit float conversion.
4480 tconfig/sun4, tconfig/sun3, xconfig/sun4, xconfig/sun3: Make
4481 equivalent to sun?os4 so global config works.
4483 Wed Jan 2 18:20:51 1991 John Gilmore (gnu at spiff.cygnus.com)
4485 Fix from Eberhard Mattes <mattes@azu.informatik.uni-stuttgart.de>
4487 * main.c: Only declare linesize once; declare pagesize not at
4488 all, since it is never used.
4489 (main): Clear newly allocated line before it is used.
4491 Fri Dec 28 00:13:42 1990 John Gilmore (gnu at cygint)
4493 Further stabilization for the Intel 960.
4495 * Makefile.dist: Parameterize the location of the "include"
4496 and "bfd" directories, as well as "getopt". Add symfile.c.
4497 Link in both dbxread and coffread. Fix up "make depend" to
4498 rewack the locations of include, bfd, and getopt in its output.
4500 * README: Document moving include files, improve some of
4503 * coffread.c: Move common code out to symfile.c. Change
4504 symbol_file_command style interface to use new *_symfile_init
4505 and *_symfile_read interface under BFD. Use BFD internal
4506 info to locate line table, symbols, etc.
4508 * core.c (core_fetch_registers): Rename to get_core_registers
4509 to avoid confusion with fetch_core_registers.
4510 (register_addr): Move to coredep.c, which is already machine
4511 dependent. This leaves core.c pretty clean of dependencies.
4513 * coredep.c (register_addr): Accept this routine from core.c.
4515 * dbxread.c: Move common code (with coffread.c, etc) into new
4516 symfile.c. Each psymtab now contains a pointer to the
4517 format-dependent function that knows how to read it in. Make
4519 (dbx_psymtab_to_symtab): Renamed from psymtab_to_symtab_2.
4520 (process_one_symbol): Add code to complain about a "compiler bug
4521 we muzzle here", if we actually see it.
4523 * eval.c (evaluate_subexp): Insert missing "break" statements
4524 in code that determines whether a variable is an lvalue in
4525 memory, register, or whatever. I detected this via a compiler
4526 bug in which it *almost* mashed out the whole switch statement.
4528 * gdb-int.texinfo: Add minor sections on configuring gdb for
4529 release, and about the README file.
4531 * infcmd.c (registers_info): Fix formatting somewhat. Still
4532 not as pretty as before, but it handles byte swapping.
4534 * remote-nindy.c: If data cache routines are interrupted while
4535 waiting for the remote end, be sure that any uninitialized cache
4536 blocks are on the free list, not on the valid list!
4538 * symfile.h: Flesh out this header file with all the various
4539 routines and variables that have been merged in from dbxread.c
4540 coffread.c, and symtab.c to symfile.c.
4542 * symfile.c: New file, containing code common to dbxread.c,
4543 coffread.c, and some code from symtab.c. All generic code for
4544 reading symbol files should be in here now.
4545 (unrecord_misc_function): Remove unused function.
4547 * symtab.h: Remove file-reading things to symfile.h.
4549 * symtab.c: Remove file-reading things to symfile.c.
4551 * tm-i960.h: Fix FRAME_CHAIN types; define PRINT_RANDOM_SIGNAL
4552 to decode i960 fault types.
4554 * target.h, remote.c, remote-eb.c, remote-vx.c, remote-nindy.c,
4555 target.c: Change type of the "resume" function from int to void,
4556 since its result was never used.
4558 Sat Dec 22 02:51:40 1990 John Gilmore (gnu at cygint)
4560 * main.c: Replace "stupid" with "caution"; you now "set caution
4563 * printcmd.c (print_scalar_formatted): Fix typo in 'g' format
4565 * infcmd.c (do_registers_info): Call val_print to deal with the
4566 byte order of the registers being printed. FIXME, this makes
4567 the formatting of the output uglier.
4569 * infcmd.c (wait_for_inferior): If PRINT_RANDOM_SIGNAL is
4570 defined, call it for signals the debugger doesn't itself use.
4571 The i960 uses this for more detailed fault information.
4573 * remote.c (remote_open): If arg is null, print help rather than
4576 * sparc-xdep.c (register_valid): Avoid declaring size, since
4577 various modules will think of various sizes depending on the
4578 architecture of their tm-file. FIXME, we need protection against
4579 actually entering one of those modules, which would clobber
4580 storage if not for the target architecture compiled into gdb.
4582 * stack.c (up_command, down_command): Always print the frame
4584 (up_silently_command, down_silently_command): New commands
4587 * i960-pinsn.c (reg), i960-tdep.c: Lint.
4589 * i960-tdep.c (i960_frame_chain_valid): Lookup_symbol now takes
4590 more parameters than it used to.
4592 * findvar.c (registers): Increase slop to 256 bytes, which should
4593 protect us against even most RISC machines with large register
4595 (locate_var_value): Move declaration inside related ifdef.
4597 * remote-nindy.c (): Use TIOCSETN rather than TIOCSETP
4598 throughout, to avoid throwing away buffered input from the board.
4599 (nindy_wait): Supply_register takes addr_of_value, not value.
4600 (i960_print_fault): Renamed from i80960_fault.
4601 (nindy_fetch_registers): Avoid have_regs stuff, just get them.
4602 (nindy_store_registers): Avoid regs_changed stuff, just stuff
4604 (nindy_create_inferior): Don't bother to write PC_REGNUM since
4605 we can set the PC in the call to proceed(). Unpush nindy_ops
4606 before pushing it on top, to avoid message to user. Eliminate
4607 commentary from Unix machines that just misleads here.
4608 (reset_command): Fix error message to suggest target command.
4610 Wed Dec 19 11:03:56 1990 John Gilmore (gnu at cygint)
4612 Release 3.92.5 as frozen.
4614 Stabilize the merged release...with help from lint, Saber C,
4617 Everywhere: Add include files needed to declare return types
4618 of functions called.
4620 * gdb.texinfo: Roland Pesch is documenting gdb, glory be!
4622 * breakpoint.h: Add undeclared breakpoint functions, and some
4623 functions for display handling since I couldn't think of a better
4626 * breakpoint.c (insert_breakpoints): Make code for disabling
4627 shared library bkpts more likely to work. It's used when we
4628 rerun a program and stop before the shared library has been
4630 (breakpoint_cond_eval, bpstat_stop_status): Pass arg as int,
4631 cast from pointer, so it squeezes through catch_errors.
4632 (bpstat_stop_status): Fix logic broken some time ago. We now
4633 always create a bpstat if the stop address matches a breakpoint,
4634 even if we don't stop there -- just like the old code used to do
4635 before I got my fingers into it (sigh).
4636 (breakpoint_1): Print "ignore count" after "stop only if"
4637 condition, since that's how it actually works.
4638 (mention): Handle watchpoints as well as breakpoints.
4639 (watch_command): use set_raw_breakpoint and mention to do most
4640 of the work (and initialize all the fields!). Only pass one
4641 arg to parse_c_expression, since that's all it takes.
4643 * command.c (not_just_help_class_command): Rename arg to args
4644 since we ignore "unused argument" warnings on vars named "args".
4645 inflow.c (child_terminal_info): ditto.
4646 infptrace.c (kill_inferior): ditto
4647 main.c (catch_errors, version_info, quit_command, pwd_command,
4648 source_command, dump_me_command, editing_info,
4649 set_history_size_command, set_history, show_history,
4651 stack.c (locals_info): ditto
4652 target.c (target_files_info): ditto
4653 valprint.c (set_input_radix, set_output_radix): ditto
4655 * core.c: Remove old variables for handling core and exec file
4656 sections (data_start, data_end, stack_start, stack_end,
4657 reg_stack_start, reg_stack_end, reg_stack_offset, text_start,
4658 text_end, exec_data_start, exec_data_end, text_offset,
4659 exec_data_offset, data_offset, stack_offset). They're
4660 superseded the more general build_section_table and
4662 (get_exec_file): Mention the `file' command.
4663 (read_memory_check): Rename to memory_error, and only call it
4664 in the case of an actual error.
4665 (read_memory, write_memory): call memory_error.
4666 (core_fetch_registers): Register section name is ".reg".
4668 coredep.c: Remove a bunch of crud now that all this file does
4669 is pull the registers out of a core file.
4670 (fetch_core_registers): Rewrite to actually work, I hope.
4672 dbxread.c: Use a.out.gnu.h, not system a.out, now.
4673 Replace index() with strchr(). Remove all the pre-BFD macro
4674 definitions for accessing the symbol file.
4675 (struct dbx_symfile_info): Encapsulate the information that
4676 dbx_symfile_init needs to pass to dbx_symfile_read in this
4679 (dbx_new_init, dbx_symfile_init, dbx_symfile_read,
4680 dbx_symfile_discard): Rearrange symbol file reading to divide
4681 the format-specific part from the format-independent part,
4682 leaving the format-independent part such as file name expansion
4683 and opening in symtab.c. This replaces
4684 partial_symbol_file_open and partial_symbol_file_read.
4685 Symbol_file_read, add_file, add_file_target_command,
4686 add_file_addr_command move to symtab.c. Pass an explicit
4687 "mainline" flag for when reading the main symbol table, rather
4688 than relying on the offset address to be zero or nonzero.
4690 (dbx_symfile_read): Don't allow void *'s to be printed as
4692 (SWAP_SYMBOL): Use bfd routines to byte-swap the symbols.
4693 (ADD_PSYMBOL_TO_LIST): Make the "function call rather than
4694 macro" debug version really work.
4695 (read_dbx_symtab): Remove unref'd parameter inclink.
4696 Avoid swapping N_SLINE symbols, for speed.
4697 Merge N_TEXT!N_EXT case with the other external symbol
4698 definitions' case. Add comments.
4699 (start_psymtab): Allocate the symfile name in the psymtab on
4700 the psymbol_obstack, rather than using the caller's storage.
4701 (end_psymtab): Only allocate a dependencies list if there are
4703 (psymtab_to_symtab_2): Use BFD when reopening file to read
4704 its symbols for real.
4705 (read_struct_type): Add FIXME comments where it needs work
4707 (read_huge_number): Add FIXME about overflows.
4708 (read_range_type): Add FIXME about comparing a long to 1<<32.
4710 * coffread.c: Minor changes to move things closer to the new
4711 regime with symtab.c and dbxread.c Major work is still needed
4714 * exec.c (exec_file_command): Remove old variables (see core.c
4716 (xfer_memory): If memory transfer is right at the end of a
4717 section, don't lose.
4719 * findvar.c (get_saved_register): If value is in a real
4720 register, LVAL is lval_register, not lval_memory.
4722 frame.h: Declare print_sel_frame and record_selected_frame.
4724 gdb-int.texinfo: New file, for GDB internals documentation.
4725 Very simple, unformatted doc of cleanups is there for now.
4727 gdbcore.h: Remove obsolete variables that described a.out
4728 section addresses and offsets. (See core.c above.)
4729 Declare fetch_core_registers and registers_fetched.
4731 getopt.c: Declare char *alloca(); even on SPARC.
4733 infcmd.c (run_command): Call target_kill rather than
4735 (step_command, next_command, stepi_command, nexti_command):
4736 Declare from_tty parameter even though we don't use it.
4737 (run_stack_dummy): argument BUFFER is a char array, not
4738 a pointer to REGISTER_TYPE.
4739 (finish_command): using_struct_return needed a value *,
4740 not a struct symbol *.
4742 * infptrace.c (child_xfer_memory): To avoid dependency on
4743 where sections are in memory, try PT_WRITE_D and if that fails,
4744 try PT_WRITE_I. Most Unixes don't care which you use.
4746 * infrun.c (step_resume_break_shadow): Change to array to
4747 match other breakpoint shadow storage.
4748 (clear_proceed_status): Pass address of bpstat to
4749 bpstat_clear, not the bpstat itself.
4750 (child_create_inferior): FIXME comment about if the child
4752 (start_inferior): Remove old function.
4753 (child_open): Use target_kill rather than kill_inferior.
4754 (wait_for_inferior): Ditto.
4755 (insert_step_breakpoint, remote_step_breakpoint): Use
4756 new step_resume_break_shadow.
4758 * inftarg.c (child_wait): If all child processes die,
4759 pretend that the one being waited for exited with signal 42.
4761 * main.c (command_line_input): When scanning for comments,
4762 don't coredump on unclosed quotes.
4763 (quit_command): Use target_kill rther than kill_inferior.
4764 (_initialize_main): Rename class_user from "user" to
4767 * printcmd.c (print_command_1): Initialize "fmt" if no format
4768 is specified by the user.
4769 (print_frame_args): Only add to args_printed if we are
4770 actually fetching args from the stack (avoiding undefined
4772 (_initialize_printcmd): Remove bogus \{ from string.
4774 * remote-eb.c (eb_open): Avoid coredump on no argument.
4776 * remote-nindy.c: Bring out of Intel environment into new
4777 target environment. Remove all conditional compilation on
4778 I80960. Massive hacking throughout.
4779 (nindy_xfer_inferior_memory): New routine stolen from
4781 (nindy_create_inferior): New routine pieced together, probably
4782 not quite working yet.
4783 (nindy_ops): New target_ops struct for nindy.
4785 * remote-vx.c: Use write_memory rather than target_write_memory
4786 to get error checking.
4787 (vx_add_file_command, vx_open): Use symbol_file_add rather than
4789 (vx_create_inferior): Use target_terminal_ours...
4791 * signame.c (_initialize_signame): Always initialize, since
4792 we need the table for things other than psignal.
4794 * solib.c (solib_add): Use symbol_file_add, not add_file.
4795 (solib_address): Return boolean result rather than struct
4796 pointer which nobody else knows the type of.
4798 * sparc-tdep.c, valops.c: Use write_memory rather than
4799 target_write_memory, to get error checking.
4801 * stack.c (locals_info, catch_info, args_info,
4802 get_selected_block, frame_command, up_command): Use
4803 target_has_stack, rather than have_inferior_p or
4806 * sun3-xdep.c (fetch_core_registers): Rewrite for new BFD regime.
4808 * symfile.h: New file, defining the interface between the
4809 generic and object-file-specific symbol reading code.
4811 * symtab.c: Move generic symbol-reading interface to symtab.c,
4812 from dbxread.c, coffread.c, mipsread.c, etc. Add symtab_fns
4813 table to map BFD targets to symbol-reading modules in GDB.
4814 Change index to strchr.
4815 (lookup_struct_elt_type): Use error() rather than hand-made
4816 simulations thereof.
4817 (lookup_partial_symbol): Speedup slightly when length == 0.
4818 (symbol_file_add): New function.
4819 (symbol_file_command): Call it.
4820 (symfile_open, symfile_init): New function.
4821 (add_file_target_command, add_file_addr_command): moved from
4824 * target.c (target_command): use target_kill.
4826 * target.h (target_files_info): Don't declare, never called
4829 * tm-sun2.h, tm-sun3.h (STACK_END_ADDR): Use system include
4830 files to determine stack end address.
4832 * valarith.c (value_x_binop, value_x_unop): Change error message
4833 to be more useful. Pass proper argument to value_struct_elt.
4835 * valops.c (value_assign): FIXME comment that long long
4836 bitfields will break here.
4838 * Makefile.dist: Add symfile.h, remote-nindy.c, remote-eb.c.
4839 Update `make saber_gdb' to work better.
4841 * TODO: A woman's work is never done.
4843 * cplus-dem.c, environ.c, inferior.h, infrun.c, inftarg.c,
4844 main.c, obstack.c, printcmd.c, remote-eb.c, remote-nindy.c,
4845 remote-vx.c, remote.c, solib.c, source.c, sparc-pinsn.c,
4846 sparc-tdep.c, sparc-xdep.c, symmisc.c, symtab.c, symtab.h
4847 target.c, terminal.h, tm-sparc.h, tm-sunos.h, utils.c,
4848 valops.c, valprint.c, exec.c: Lint.
4851 Wed Dec 12 23:44:15 1990 John Gilmore (gnu at cygnus.com)
4853 Continuing Intel 960 port merge of GDB.
4855 * Makefile.dist: Merge i960 "nindy-share" files. Rename
4856 malloc.h to gmalloc.h to avoid name conflicts in /usr/include.
4857 Don't ship gdb.dvi in tar file. Link gdb with init.o, not init.c.
4858 Wack over "make depend" so it handles files in subdirectories
4859 vx-share, nindy-share, bfd, and in the current directory.
4861 * blockframe.c (get_prev_frame_info): Remove fatal error
4862 if stack not defined.
4864 * core.c (core_open, core_detach): New functions that handle
4865 the old "core-file" command as "target core" and "detach" instead.
4866 (core_file_command): Call them.
4867 (core_xfer_memory): Use common routine xfer_memory.
4869 * dbxread.c: Include a.out.gnu.h, not system a.out.h.
4870 dbxread now uses bfd for everything but symbol reading itself.
4871 BFD internals are used to drag out the relevant file offsets.
4872 (partial_symbol_file_open): Change args all around for BFD.
4874 * symtab.c: Rename "value" to "val" everywhere, so we can
4876 (symbol_file_command): New command, moved from dbxread.c
4877 and coffread.c. It uses BFD to read the file, then vectors
4878 based on its type, to dbx or coff symbol readers.
4879 * symtab.h: Extern a few vars for symbol_file_command.
4881 * target.h: Breakpoint takes a char * save area, not a char **.
4883 * valprint.c (val_print): When unpacking bitfields, offset
4884 the address in gdb of the value, if it is declared with a shorter
4885 type. Remove the last "runtime kludge test" of host byte order.
4887 * utils.c: Remove old my_bfd_read routine.
4889 * stack.c (frame_info): Use target_has_stack. Print program counter
4890 register's actual name rather than "pc", since it's called the
4891 "ip" (instruction pointer) on the i960 (sigh).
4893 * target.c (target_command): Add command for selecting a target
4894 type and calling its open routine. This is used for initiating
4895 communication with a particular target, in a generic way.
4897 * tm-i960.h: Update for modern gdb. Remove semicolons from
4898 various macros. Handle reading struct return convention, and
4899 error-out attempts to return structs with the "return" command.
4900 Be sure gdb doesn't think we know how to call functions in the
4903 * i960-tdep.c: Rename FRAME_CHAIN_VALID and FRAME_FIND_SAVED_REGS
4904 to i960_xxx in lower case.
4905 (arg_address): Circumvent errors due to LOC_ARG_BLOCK
4906 not being defined yet.
4908 * remote.c (remote_open): Call start_remote to initialize
4909 wait_for_inferior during open.
4910 (remote_xfer_inferior_memory): Return length written rather
4913 * remote-vx.c (target_command -> vx_open): Use new generic
4915 * remote-eb.c, inftarg.c, exec.c: ditto.
4917 * infrun.c: Fix comments.
4918 (attach_program -> child_open): Use new generic target command.
4919 (wait_for_inferior): Clear saved register values before target_wait,
4920 so target_wait can set some of them if convenient.
4922 * infptrace.c (fetch_inferior_registers, store_inferior_registers):
4923 Return success indicator, not void.
4924 (child_xfer_memory): Avoid fetching initial word if we'll
4925 overwrite it anyway.
4927 * infcmd.c (attach_command): Use new generic target open routine.
4928 (_initialize_infcmd): Update doc on attach and detach commands.
4929 (do_registers_info): Merge in a byte-order problem as a FIXME
4932 * findvar.c (find_saved_register): Avoid problem in current frame.
4933 (read_relative_register): Ditto.
4934 (write_register): Convert byte order on the way out.
4936 * exec.c (file_command): Add.
4937 (add_to_section_table, exec_command): Use new bfd_map_over_sections.
4938 (xfer_memory): Common function between core_xfer_memory and
4940 (exec_xfer_memory): Use it.
4942 * pn-opcode.h: Document that a "PN" is a Gould PowerNode.
4944 * breakpoint.c, breakpoint.h, symtab.h, value.h, frame.h, utils.c,
4945 valops.c, stack.c, target.c, sparc-xdep.c, source.c, printcmd.c,
4946 infcmd.c, i960-pinsn.c, eval.c, defs.h: lint and gcc -Wall.
4948 Sun Dec 2 16:45:06 1990 John Gilmore (gnu at cygnus.com)
4950 Merge Intel 960 port of gdb, continuing...
4952 * dbxread.c (partial_symbol_file_open, partial_symbol_file_read,
4953 symbol_file_command): Pass from_tty arg to hush 'em up.
4955 * coffread.c (symbol_file_command): Avoid output if from_tty != 1.
4956 Add magic numbers for 960 COFF format.
4958 Fri Nov 30 09:18:20 1990 John Gilmore (gnu at cygnus.com)
4960 Merge Intel 960 port of gdb, from Intel "1.2" release.
4962 CHANGE_LOG entries from their port, which was based on
4965 Thu Sep 6 11:02:22 PDT 1990
4966 Remove temp file if download is interrupted.
4968 Wed Aug 1 09:08:33 PDT 1990
4969 Now uses binary protocol to talk to NINDY.
4970 Old hex protocol (NINDY 2.13 and older) supported with -O switch.
4971 Times out after 5 seconds when trying to talk to NINDY.
4973 Tue May 29 12:54:49 PDT 1990
4974 Added variable baud rate (-b switch).
4975 Source code reorganization.
4977 Thu Apr 26 11:09:55 PDT 1990
4978 More cleanup of batch mode; specifically, execute "-s", "-e", and
4979 "-se" switches as soon as they are encountered on the invocation line.
4981 Fri Apr 20 13:47:15 PDT 1990
4984 Thu Apr 19 09:54:28 PDT 1990
4985 Add 'reset' command.
4987 Wed Apr 18 09:48:07 PDT 1990
4988 After opening remote tty, wait for 1 second to go by without input
4989 from it before trying to talk to NINDY (fixes problems with the
4990 Heurikon HK80/V960E).
4992 Mon Apr 4 16:33:05 PDT 1990
4993 Some output was not being suppressed in 'batch' mode.
4995 Thu Mar 22 15:31:11 PST 1990
4996 Ask user if old symbol table should be deleted when new file is
4999 Allow user to run a program downloaded before gdb960 was brought up.
5001 Correct "exec-file" help message for i80960 context.
5003 Correct bug in calculating user space address: could occasionally
5004 corrupt user program.
5006 Make sure to zero low-order bits in rip's because of bug in 960CA
5007 A-step part: could cause operation faults when "next"ing across
5010 Correct bug that made it impossible to get source line numbers for
5011 code loaded at addresses higher than 0x7fffffff.
5013 Wed Jan 10 12:43:22 PST 1990
5014 Open remote tty for exclusive use.
5016 Fri Jan 5 12:14:42 PST 1990
5017 Correct disassembly (CA manual was right after all):
5018 opcode for sysctl is 0x659
5020 Mon Oct 23 12:03:04 PDT 1989
5021 Use G960BASE and G960BIN environment variables to find 'sx' utility.
5023 Mon Oct 16 14:15:09 PDT 1989
5024 "sfr0"-"sfr31" should have been named "sf0"-"sf31"
5026 Mon Oct 2 15:56:31 PDT 1989
5028 Added 960CA disassembly support.
5030 To simplify maintenance:
5031 - eliminated use of symblic links on pinsn.c: use i960-pinsn.c
5033 - eliminated opcode.h: incorporates tables into i960-pinsn.c
5034 - moved 960-specific routines from i960-pinsn.c to i960-md.c
5035 - made disassembly interface identical to that in gdmp960.
5039 Wed Nov 28 21:32:48 1990 John Gilmore (gnu at cygint)
5041 * target.h: Allow targets to stack. Add target_has_memory,
5042 _registers, etc. Restructure memory access and "info files"
5043 to walk the target stack.
5044 * exec.c, core.c, inftarg.c, remote.c, remote-vx.c, remote-eb.c,
5045 target.c: Change tables to match target.h.
5046 * inflow.c (child_mourn_inferior): pop child_ops.
5047 (generic_mourn_inferior): Use new has_stack flag.
5048 * infptrace.c (child_xfer_memory): New memory regime.
5049 * inftarg.c (child_files_info): New "info files" regime.
5050 * remote-eb.c: New memory regime, new info files.
5051 * remote-vx.c: New memory regime, new info files. Now use
5052 separate targets for VxWorks attachment to machine, and
5053 actually running a process under VxWorks, since one has
5054 stack & execution & regs and the other doesn't.
5055 * remote.c: New memory regime, new info files.
5056 * sparc-xdep.c (fetch_core-registers): New memory regime.
5057 * target.c: New routines and support for stacked targets,
5058 new memory regime, new info files regime.
5061 Generalize section handling for an arbitrary number of sections,
5062 including use of the new BFD (binary file) library.
5063 * gdbcore.h: Add struct section_table.
5064 * exec.c (build_section_table): Iterate all sections and
5065 record what gdb needs to know about them.
5066 (exec_command): Use it.
5067 (exec_xfer_memory): Use the table.
5068 (exec_files_info): Print the table.
5069 * core.c (core_file_command, core_xfer_memory, core_files_info):
5071 * source.c (find_source_lines): Use bfd_get_mtime.
5072 * dbxread.c: Quick changes to make it compile with new BFD.
5073 * utils.c (error): Avoid using bfd_error in generic routines.
5075 * core.c (core_fetch_registers): Get from the ".regs" section of
5077 * sparc-xdep.c (fetch_core_registers): Use the .regs info.
5079 * inferior.h (attach_flag): Export.
5080 * infcmd.c (run_command): use new target_create_inferior.
5081 * infrun.c (child_create_inferior): Don't return result.
5082 * Makefile.dist (VERSION): 3.91.4.
5084 Fri Nov 23 28:15:38 1990 John Gilmore (gnu at cygint)
5086 * breakpoint.c (bpstat_num): Handle breakpoints which have
5087 since been deleted, such as temporary breakpoints.
5088 infcmd.c (program_info): ditto.
5090 * core.c (core_file_command): Display the frame where the core
5095 * remote-vx.c (target_command): Merge in target command from
5096 targ-vx.c. A few other cleanups.
5098 * TODO, Projects: Lots more stuff to do...
5100 Fri Nov 23 18:15:38 1990 John Gilmore (gnu at cygint)
5102 Massive changes to wall off the remote-debugging interface
5103 behind a function vector. The port to handle VxWorks targets
5104 is also part of this.
5106 All files: Replace references to renamed functions,
5107 remove references to remote_debugging, remove references to
5108 have_include_file, have_core_file in favor of target_has_stack,
5109 target_has_memory, etc.
5111 * Modularize the breakpoint interface.
5112 breakpoint.h (BREAKPOINT_MAX): New define sets max length of
5113 a breakpoint instruction.
5114 breakpoint.c: struct breakpoint's shadow_contents now sized as
5116 (insert_breakpoints): Vector to target to install breakpoints.
5117 (remove_breakpoints): Vector to target here too.
5118 Remove REMOTE_SA_SPARC kludges and other remote_debugging.
5119 sparc-tdep.c (single_step): Use new breakpoint interface for
5120 the single-step breakpoints.
5121 mem-break.c (memory_insert_breakpoint, memory_remove_breakpoint):
5122 New file, contains routines to insert and remove breakpoints by
5123 reading out the old contents and later replacing them. This is
5124 how ptrace breakpoints work, and many remote systems as well.
5126 * tm-vxworks68.h: New config file, overrides a few things for
5127 Wind River's preferences.
5129 * target.h: New file, for transfer vector used to talk to the
5130 inferior (child, attached, core, exec, remote, etc). All accesses
5131 to the thing being debugged should come through these vectors.
5132 target.c: New file, routines to handle transfer vector.
5133 (various files): Add transfer vectors XXX_ops for the various
5134 targets and pseudo-targets (core files, etc) we support.
5136 * breakpoint.c (bpstat_stop_status): Further explorations of
5137 watchpoints and why things don't work all the time.
5138 (bpstat_alloc): New fn to allocate a bpstat and chain it.
5140 * config.gdb: Only add "source ${srcdir}/.gdbinit" to
5141 the local gdbinit if it doesn't already have it.
5143 * core.c (core_ops): add and install.
5144 Allow core debugging without exec file.
5146 * dbxread.c (free_and_init_header_files): Merge two fns.
5147 (end_symtab): Free named symbol table when a new version comes in.
5148 (read_dbx_symtab): Relocate all kinds of symbols with base
5149 address. First step toward handling different text, data, bss
5151 (add_file_addr_command): Renamed add_file_command.
5152 (add_file_command): Vector to remote handler.
5153 Add "load" as an alias for "add-file" command.
5155 * defs.h: Allow "volatile" to be used in non-ANSI; use it for
5156 non-returning functions.
5158 * exec.c: Add exec_ops, and push it as a target when an exec
5161 * infcmd.c (run_command): Pass executable file name and arg list
5162 separately when starting an inferior. Permit "run" when no exec
5163 file is specified, for VxWorks.
5164 (detach_command): Move to child_detach in inftarg.c.
5166 * inftarg.c: New file. Unix-child-specific routines, and the
5167 child_ops structure.
5169 * inferior.h (registers): Export "registers" as the way for
5170 target dependent register handlers to find gdb's local copy of
5171 the registers. Rename "stop_after_attach" to "stop_soon_quietly"
5172 since it is now used by places that want wait_for_inferior to
5173 handle the grunge but want to see every trap from the inferior.
5175 * inflow.c (create_inferior): Pull out, and merge into infrun.c.
5176 Eliminate remote_debugging hooks in terminal handling.
5178 * infrun.c: Replace start_inferior with child_create_inferior.
5179 Move all the hair of Unix shells and ptrace idiosyncracies into
5180 child_create_inferior, so remote handlers don't have to deal.
5181 Remove running_in_shell. Rename stop_after_attach to
5182 stop_soon_quietly, and use it in a few other places where we want
5183 to just call wait_for_inferior and get control back on the first
5184 trap. trap_expected now never takes a value > 1.
5185 (init_wait_for_inferior): Initialize static vars when a new
5188 main.c (gdbinit): Add new hook for .gdbinit file name, let
5189 it be overridden by config files as GDBINIT_FILENAME.
5190 (DEFAULT_PROMPT): Add new hook for overriding (gdb) prompt.
5191 Both of these are used for VxWorks gdb.
5193 mcheck.c: rename include file "gmalloc.c" to avoid problems
5194 with system include file "malloc.c".
5196 param-no-tm.h: New include file, same as param.h but does not
5197 include the default "tm.h" file. This is used in files where
5198 the target is known, e.g. remote-eb.c or sparc-xdep.c.
5200 param.h: Now just a shell that includes tm.h and param-no-tm.h.
5202 remote-vx.c: New file, VxWorks remote debugging support. Uses
5203 RPC routines that are shared with the target system, in directory
5206 remote.c: Vectorize remote interface.
5208 source.c: Globalize source_path, and make an alias "l" for "list"
5209 since we now have the "load" command.
5211 sparc-xdep.c: Use new param-no-tm.h.
5213 symmisc.c (free_named_symtab): Add new function from Wind River.
5214 However, ifdef it out for now while we think about what it should
5217 tm-sun3.h, xm-sparc.h, xm-sun3.h, xm-symmetry.h: Move
5219 the xm- file, and change its name to CHILD_PREPARE_TO_STORE, since
5220 non-Unix-children handle this with their own code in the target
5223 Makefile.dist: Roll version to 3.92.3. Add vx-share stuff to
5224 source and target lists. Add vx-share to default list of include
5225 directories. Add new files to src and target lists: mem-break,
5226 target, inftarg, remote-eb, remote-vx, targ-vx. Be sure the
5227 ${srcdir} versions of munch and createtags are used.
5229 * valops.c (find_function_addr): Split out of call_function.
5230 (call_function_by_hand): Rename call_function; this function
5231 calls functions in the target by laboriously patching the target
5232 word-by-word with the right stack, args, regs, etc.
5235 Mon Nov 5 17:29:10 1990 John Gilmore (gnu at cygint)
5237 Handle AMD 29000 a bit better.
5239 * remote-eb.c (readchar): Mask received char log to make it readable.
5240 (remote_start): Pass arguments down to executing program.
5241 Make startaddr unsigned.
5242 infrun.c (start_inferior): Accept args, pass them to
5244 infcmd.c (run_command): Pass args down to start_inferior.
5246 * tconfig/am29k-aout, tconfig/am29k-coff: New files specifying
5247 the target object file format.
5248 tm-29k.h: Pay heed to COFF_ENCAPSULATE.
5250 * am29k-pinsn.c (print_insn): Print 0x on hex numbers in disassembly.
5251 am29k-tdep.c (examine_prologue): Better checking of function prefixes.
5253 Sun Oct 7 18:20:45 1990 John Gilmore (gnu at cygint)
5255 * Makefile.dist (VERSION): Roll version to 3.91.9 and freeze.
5256 * TODO: We did a few things, we have more to do though.
5258 * xm-sparc.h (CLEAR_DEFERRED_STORES): Define.
5259 * inflow.c (inferior_died): Clear deferred stores.
5261 * Debug problems with dummy frames and calls to the inferior.
5262 * tm-sparc.h (PUSH_DUMMY_FRAME, POP_FRAME): Move to sparc-tdep.c.
5263 * sparc-tdep.c (do_restore_insn): Simplify.
5264 (sparc_frame_find_saved_regs): Simplify and fix what we find.
5265 (sparc_push_dummy_frame): Simplify and fix what we push.
5266 (sparc_pop_frame): Slightly more hair here, deciding whether
5267 we are restoring a saved PC or returning to a return address in %i7.
5268 * sparc-xdep.c (read_inferior_registers): Debug if valid reg is read.
5270 * utils.c (xmalloc, xrealloc): Return type depends on __STDC__.
5271 * symtab.h (xmalloc): ditto, for obstack_chunk_alloc.
5272 * obstack.h (chunkfun): ditto.
5273 * defs.h (xmalloc, xrealloc): ditto
5275 * utils.c (quit): Grab the terminal from the child if necessary.
5277 * inflow.c (term_status_command): Rename to term_info, change
5280 * sparc-pinsn.c (print_insn): Disassembly prefers real instructions.
5281 (is_delayed_branch): Speed up.
5282 * sparc-opcode.h: Add ALIAS bit to aliases. Fix up opcode tables.
5283 Still missing some float ops, and needs testing.
5285 * Support for input and output radixes other than base 10
5286 * defs.h (input_radix, output_radix): Declare.
5287 * expread.y (yyparse, parse_number): Handle changes of input
5288 radix, and ambiguous names-or-numbers in radixes >10.
5289 * printcmd.c (print_scalar_formatted): Print formatted hex
5290 numbers in varying column widths.
5291 * valprint.c (val_print): Use output_format to print scalar ints.
5292 (set_input_radix, set_output_radix, set_radix): Create.
5293 (set_output_radix): Set output_format from output_radix.
5294 (_initialize_valprint): add `set radix' but leave the others off.
5296 * main.c (execute_command): Let stupid questions be turned off.
5297 (_initialize_main): Handle "set stupidity", etc.
5299 * main.c, inflow.c, inferior.h, frame.h, command.c, defs.h,
5300 sparc-pinsn.c, sparc-xdep.c, value.h, valops.c, values.c: Lint.
5302 Tue Oct 2 11:20:02 1990 John Gilmore (gnu at cygint)
5304 * TODO, Makefile.dist, ChangeLog: Freeze for 3.91.8 release.
5305 bfd stuff is still screwed up, but with some manual work, it
5308 * breakpoint.c (bpstat_do_actions): Start over if a command
5309 proceeds the inferior, since the inferior will have stopped and
5310 will need to have its new stop-actions taken care of.
5312 * dbxread.c (read_struct_type): Expression gives Sun3 4.0.3
5313 compiler fits, simplify it.
5315 * gdb.texinfo (directory command): Doc new dir command.
5316 source.c (directory_command): "dir" now puts things on the front
5317 of the path, moves dups up front, and handles multiple names
5318 on the command line, inserting each one in order. It also
5319 blows away cached line and full_filename info.
5321 * stack.c (backtrace_command): Skip "more stack frames follow"
5324 * Change #ifndef HAVE_VPRINTF to #define MISSING_VPRINTF in
5325 xm-convex.h, xm-hp300bsd.h, xm-isi.h, xm-merlin.h, xm-news.h,
5326 xm-np1.h, xm-pn.h, xm-pyr.h, xm-symmetry.h, xm-umax.h, xm-vax.h.
5327 The only odd one was Gould NP1, which had defined vprintf to
5330 * Merge Ted Goldstein <tedg@Eng.sun.com>'s changes for epoch.
5331 printcmd.c (print_command_1): Pass 'inspect' flag down as a global
5332 variable, inspect_it.
5333 valprint.c (print_string, val_print): Use the global inspect_it
5334 to indicate whether to print in Epoch style or normal style.
5336 Mon Oct 1 23:55:26 1990 John Gilmore (gnu at cygint)
5338 * printcmd.c (call_command): add an alias for the "print" command
5339 which runs expressions and doesn't print the result if void.
5340 (print_command_1): implement it.
5342 * command.c: Remove #if 0'd code. Initialize all the fields
5343 in add_cmd (). Rename do_nothing_command to
5344 not_just_help_class_command, and make it externally visible.
5345 command.h: add user_commands to struct.
5346 * main.c (define_command): Don't overload c->function with a char
5347 string as well as a function pointer.
5349 * eval.c (evaluate_subexp): Reinstall tiemann changes to
5350 calling convention of value_struct_elt () that got dropped in
5353 * tm-sparc.h (FRAME_FIND_SAVED_REGS): move to sparc-xdep.c.
5354 sparc-tdep.c (sparc_frame_find_saved_regs): ditto.
5356 * tm-sparc.h (POP_FRAME): replace some constants with defines.
5358 * sparc-xdep.c (store_inferior_registers): defer stores to regs
5359 until a good time (e.g. when we are about to run the child),
5360 saving ptrace calls.
5361 * infrun.c (proceed): handle DO_DEFERRED_STORES.
5362 * tm-sparc.h: define DO_DEFERRED_STORES.
5364 * sparc-xdep.c (store_inferior_registers): when storing float
5365 registers, don't store stack regs too. When storing the SP,
5366 however, DO store the stack regs too. This fixes a bug in which
5367 the dummy frame is not recognized when a call_function finishes,
5368 because its frame pointer (in the stack regs) was never
5370 (read_inferior_registers): Mark WIM and TBR and FPS and CPS valid
5371 even though we don't know how to read them from an inferior.
5372 valops.c (call_function): Comment about storing SP.
5374 * infrun.c (save_inferior_status): Save away the original bpstat
5375 chain so it can be restored later. Install the copied version for
5376 use by whoever saved the status. It will be blow away by
5377 restore_inferior_status, and the original chain restored. This is
5378 important for people who have pointers into the original.
5380 * breakpoint.c, command.h, copying.awk, dbxread.c, defs.h,
5381 findvar.c, frame.h, obstack.h, obstack.c, inflow.c, value.h,
5382 main.c, printcmd.c, sparc-tdep.c, symtab.c, valprint.c: lint
5385 Fri Sep 28 20:32:46 1990 John Gilmore (gnu at cygnus.com)
5387 * Makefile.dist: Roll version to 3.91.8. Add bfd.h and bfdconfig.h
5388 temporarily to the makefile. Add am29k-opcode.h and WHATS.NEW.
5389 Add stuff.c and kdb-start.c to the OTHERS list for tar files.
5391 Fri Sep 28 19:12:12 1990 John Gilmore (gnu at cygint)
5393 * Merge Mike Tiemann's multiple inheritance changes from Sun.
5394 Store the baseclasses in a type struct starting from array element
5395 0 rather than from the unusual array element 1.
5397 dbxread.c: the above.
5398 (virtual_context): Add
5399 Read new debug information about which virtual function table
5400 a virtual function is from, and store it in fn_field.fcontext.
5402 symtab.h: Add fcontextt. Fix baseclass indices. Typo in
5403 TYPE_FN_FIELD_STATIC_P.
5405 symtab.c: the above.
5406 valops.c: the above. Handle pointer casts of object *'s.
5407 (search_struct_method): Add.
5408 (value_struct_elt): First arg is now a pointer to a value, and is
5411 valprint.c: the above.
5412 values.c (value_virtual_fn_field): Add type arg. Handle
5413 offsetting to the proper object when calling virtual fns.
5415 (baseclass_addr): Add valuep arg.
5417 * README: Document the current state of BFD config (missing).
5418 * TODO, ChangeLog, Makefile.dist: Roll version.
5419 * WHATS.NEW: Add summary of changes since 3.5.
5421 Thu Sep 27 16:23:12 1990 John Gilmore (gnu at cygint)
5423 * dbxread.c (read_struct_type): Clear bit vectors whenever
5425 symtab.c (B_CLRALL): define.
5427 * tm-sparc.h (STORE_RETURN_VALUE): Avoid clobbering types by
5428 using == rather than =. Huh... This fixes the dreaded problem
5429 wherein builtin_type_int becomes TYPE_CODE_FLT.
5431 * core.c (info_files): Show the inferior pid.
5433 * config.gdb: Avoid putting "dir" command into .gdbinit. GDB
5434 already knows how to look in the source directory.
5436 * Remove psymtab hair from many places. Remove duplicated code
5437 for searching symbol tables. Hide psymtabs from most places.
5438 Make it fast to get from a psymtab to its symtab.
5440 blockframe.c (blockvector_for_pc): Remove psymtab hair.
5441 coffread.c (psymtab_to_symtab): Rename to psymtab_to_symtab2.
5442 mipsread.c (psymtab_to_symtab): Rename to psymtab_to_symtab2.
5443 dbxread.c: export psymtab_to_symtab, make it work if called N times.
5444 (psymtab_to_symtab): Rename to psymtab_to_symtab2. Initialize
5445 new symtab completely. New psymtabs get symtab pointer
5446 initialized to zero. Remove MI warning printf.
5447 symtab.h: Comments. Add psymtab to symtab pointer.
5448 (PSYMTAB_TO_SYMTAB): New macro.
5449 symtab.c: use PSYMTAB_TO_SYMTAB. Add psymtab_to_symtab and export it.
5450 source.c: use PSYMTAB_TO_SYMTAB. Remove symtab version and
5452 stack.c (backtrace_command): Avoid pre-pass to read symbols, if
5454 (print_frame_info): Avoid special-casing symbols that have not yet
5457 * source.c (open_source_file): Quick path if we have already
5458 located the source file by its full name.
5460 * symtab.c (lookup_symbol): Use find_pc_symtab rather than
5461 find_pc_psymtab. When a name is found in the misc function
5462 vector, search the symbol table for its mangled name, not the
5463 name that the user typed.
5465 * bfd.h: Fix missing comment terminators, make #endifs match.
5467 * valarith.c (value_less): Handle unsigned int comparisons.
5468 Add FIXME about pointer compares, which assume host and target
5469 pointers are the same.
5471 * command.c (do_nothing_command): lint
5472 dbxread.c: lint. Remove sort_syms. Document C++ visibility info,
5473 fix comments on debug symbol format for visibility. Actually set
5474 visibility of symbols.
5475 main.c (echo_command): lint; use <readline/history.h>.
5476 tm-sparc.h (FRAME_FIND_SAVED_REGS): lint
5477 obstack.h (_obstack_blank): Rearrange pointer math to avoid
5478 pointing past end of allocated memory; saber complains.
5479 obstack.h: Declare the external functions that we use.
5480 valarith.h: use <string.h>
5481 solib.c (solib_add): lint.
5483 Fri Sep 21 17:05:19 1990 John Gilmore (gnu at cygint)
5485 * main.c (initialize_main): Default info_verbose to off, now that
5486 symbol reading is fast.
5487 (quit_command): Avoid clobbering exec_bfd while quitting.
5489 * Initial BFD (binary file diddling library) merger:
5490 coffread.c: Change AOUTHDR to struct exe_hdr.
5492 core.c: initialize initialized data at compile time.
5493 (core_file_command): Move from coredep.c, convert to bfd.
5494 (xfer_core_file): Convert to bfd.
5495 exec.c (exec_file_command): use bfd routines.
5497 mips-tdep.c: Remove exec_file_command and friends.
5500 * coredep.c: (fetch_core_registers) Convert core_file_command to
5501 fetch_core_registers.
5502 mips-xdep.c, sparc-xdep.c, sun3-xdep.c: ditto.
5504 * utils.c: (error): Bogus crap, FIXME, to print bfd errors.
5505 (my_bfd_read): More bogosity, which I don't think we call.
5506 (program_name): Remove this atrocity asap!
5508 Wed Sep 19 13:36:41 1990 John Gilmore (gnu at cygint)
5511 values.c: allocate_repeat_value was not clearing the
5512 optimized_out field.
5513 (value_static_field): minor stylistic fix (wrong macro was used).
5514 valops.c (value_struct_elt_for_address): didn't work for C++
5517 * signame.c (_initialize_signame): Initialize signal names once.
5519 * breakpoint.h, command.c, copying.awk, defs.h, environ.c,
5520 exec.c, frame.h, infcmd.c, inferior.h, main.c, munch, sun3-xdep.c,
5521 symtab.h, tm-29k.h, valprint.c, value.h, values.c: Lint.
5523 * remote-eb.c: Support user-settable baud rates on the serial port.
5525 * tm-sun3.h (PREPARE_TO_STORE): fix typo.
5527 Fri Sep 14 13:28:29 1990 John Gilmore (gnu at cygint)
5529 * tconfig/sun3os4: Remove warning about native assembler,
5530 since it also occurs in the xconfig file.
5532 * findvar.c (registers): Allocate some slop after `registers'
5533 to prevent stray accesses from trashing the next variable.
5535 * tm-68k.h (REGISTER_BYTES): Allocate the right number of bytes
5536 on the sun-3, by changing the #ifdef from `sun3' (which is not
5537 defined by cc) to `sun'. Symptom was trashed builtin_type_XXX
5538 vars, which happened to follow `registers' in the executable.
5540 * readline/history.c (history_search): Heed gcc-2's advice
5541 and parenthesize && inside ||).
5543 * am29k-opcode.h, am29k-pinsn.c, am29k-tdep.c, remote-eb.c,
5544 tm-29k.c: Insert FSF copyright headers.
5546 * remote-eb.c: Better comments.
5548 * Makefile.dist: Update to 3.91.6.
5549 * TODO: note PREPARE_TO_STORE problem.
5551 Thu Sep 13 09:52:33 1990 Jim Kingdon (kingdon at cygint)
5553 * stack.c (frame_info): Only use FRAME_FIND_SAVED_REGS if defined.
5555 * remote.c: Wrap the whole file in #if !defined (SPECIAL_REMOTE).
5557 * infrun.c (wait_for_inferior, at end): Don't set up
5558 prev_* if the inferior no longer exists.
5560 * inferior.h (CALL_DUMMY_LOCATION): New macro, to replace
5561 CANNOT_EXECUTE_STACK.
5562 valops.c (call_function): Use it.
5564 * tm-convex.h: Add CALL_DUMMY_LENGTH for use by PC_IN_CALL_DUMMY.
5566 * inferior.h (PC_IN_CALL_DUMMY): New macro.
5567 infrun.c (wait_for_inferior, 2 places): Use it.
5569 * values.c (value_being_returned): Only use
5570 EXTRACT_STRUCT_VALUE_ADDRESS if defined.
5572 * Move PREPARE_TO_STORE from xm-sun3.h to tm-sun3.h to do the
5573 right thing for remote-eb.c.
5575 * sun3-xdep.c: Remove extraneous call to remote_store_registers.
5576 * sun386-xdep.c, hp300hpux-xdep.c, sparc-xdep.c: Ditto.
5578 * blockframe.c: Put get_frame_saved_regs inside #if !defined
5579 (FRAME_FIND_SAVED_REGS).
5581 * findvar.c ({fetch,store}_registers): Check for
5582 REMOTE_{FETCH_STORE}_REGISTER macro.
5584 * findvar.c (get_saved_register): Add argument lval and
5585 change meaning of argument addr.
5586 findvar.c: Change calls to get_saved_register to reflect
5587 new calling convention.
5588 valops.c (value_assign): Use get_saved_register instead of
5589 find_saved_register.
5591 Sun Sep 2 12:40:20 1990 Jim Kingdon (kingdon at cygint.cygnus.com)
5593 * coffread.c (read_one_sym): Make temp_aux an AUXENT, not
5594 an (uninitialized) pointer to one. Use "&" when passing it
5597 Fri Aug 31 22:57:54 1990 Jim Kingdon (kingdon at cygint.cygnus.com)
5599 * coffread.c (getfilename): Use DGUX x_offset and x_name if
5602 * coffread.c (symbol_file_command): Put semicolon after
5604 Put safe_to_init_tdesc_context in #if defined (TDESC).
5605 Put #ifdef TDESCs in 1st column for non-ANSI cpp's.
5606 coffread.c: #include <sys/stat.h>.
5607 (read_coff_symtab): Typo: in_source_files -> in_source_file.
5608 Add missing ')' in check for "lc%" and friends. Remove
5610 Declare read_one_sym() at top of file.
5611 (read_file_hdr): Put in extra #ifdefs so MC68MAGIC and
5612 MC68WRMAGIC can have the same value without causing a duplicate
5615 Thu Sep 13 15:55:36 1990 John Gilmore (gnu at cygint)
5617 * Allow a Makefile to be built without building the
5618 tm and xm file links that screw up builds in subdirectories.
5619 This is done with `config.gdb none', then you can do things
5620 like `make gdb.tar.Z'.
5621 * tconfig/none: Config file for no target system
5622 * xconfig/none: Config file for no host system
5623 * config.gdb: If no TM or XM files are called out by the
5624 host or target file, don't make links for them.
5626 * cplus-dem.c: Add documentation.
5628 * dbxread.c (read_ofile_symtab): Turn a fatal error into a
5629 simple error, so the user's gdb doesn't crash due to some object
5630 file problem (e.g. somebody is rebuilding the file out from under
5633 * printcmd.c (print_address_symbolic): demangle the symbol.
5635 * Makefile.dist (OTHERS): Remove tdesc-lib because it has
5636 Motorola copyrights in it. Make "make gdb.tar.Z" work.
5637 (alldeps.mak): sort and uniq all results from this; duplicates
5638 hose gdb.tar.Z link building. Remove RCS files from
5639 tconfig and xconfig. Add config files for sun386. Add
5640 a few odd files to OTHERS and HFILES.
5642 Mon Sep 10 21:20:24 1990 John Gilmore (gnu at cygint)
5644 * Makefile.dist: Pull solib.c to tconfig/sun?os4.
5645 Roll version number to 3.91.5. Make lint work in bindir.
5647 * README: Document cross-debugging and new file structure.
5649 * blockframe.c: Lint. Include "value.h" to declare read_register.
5650 (find_pc_partial_function): remove duplicate line.
5652 * command.h: Lint. Declare error_no_arg and dont_repeat.
5654 * tm-news.h: Remove inadvertently duplicated stuff.
5656 * mipsread.c: Remove cache_pc_function stuff, now done cleanly.
5657 Clean up usage of misc_function_type. Declare some CORE_ADDRs.
5659 * config.gdb: Allow `config.gdb host target' form. Clean
5660 up previous change that printed bogus messages when you just said
5663 * core.c: #include "command.h" for lint.
5666 * main.c: Remove some casts of enums. Lint.
5673 * printcmd.c (initialize_printcmd): Fix thinko in inspect cmd.
5675 * sparc-tdep.c (isannulled): Take instruction as parameter, don't
5676 read it from memory. This will allow us to save ptrace calls
5677 eventually. Changed caller single_step too.
5679 * sparc-xdep.c (fetch_inferior_registers): Avoid reading regs
5680 that we aren't going to use, saving many ptrace calls, especially
5681 when watchpointing or single stepping. Use some #define's for
5683 (store_inferior_registers): Ditto.
5684 (core_file_command): Use some #define's for constants.
5686 * tm-sparc.h: Add #define's for some register numbers, so we
5687 can eliminate the use of random constants in sparc-xdep.c.
5689 * stack.c (frame_command, print_frame_info, up_command,
5690 down_command) Remove frame_changed, since it
5691 causes a bug and doesn't seem to do anything useful. In some
5692 places it was used as a flag, in others as a stack level (?).
5694 * utils.c: Use MISSING_VPRINTF rather than HAVE_VPRINTF, so the
5695 default is to use the portable (vprintf) version rather than the
5697 * xm-news.h (MISSING_VPRINTF): Add.
5699 * valprint.c (val_print): Demangle fancy vtbl printouts. Lint.
5701 Sat Sep 8 00:24:12 1990 John Gilmore (gnu at cygint)
5703 * Remove stuff that forces -Bstatic linking of gdb, and warnings
5704 about linking debugged programs -Bstatic in the sun?os4 config
5705 files in tconfig and xconfig subdirectories.
5707 * main.c (main): Remove unreached exit(0) now that we exit
5710 * Create TODO file for online bug list. There are too many
5711 "little" bugs to keep track of on paper.
5713 * Change Projects file to refer to bug-gdb@cygnus.com
5714 rather than kingdon@ai.
5716 Fri Sep 7 23:35:15 1990 John Gilmore (gnu at cygint)
5718 * Makefile.dist (VERSION): 3.91.4 now.
5720 * symtab.c (init_misc_bunches): Rename from init_misc_functions.
5721 (condense_misc_bunches): Add sanity check that misc_count is
5722 the same as the number of symbols in the bunch.
5724 * coffread.c: rename init_misc_bunches. Pass an argument
5725 to condense_misc_bunches (a zero).
5727 * dbxread.c (partial_symbol_file_read): Call init_misc_bunches
5728 every time we are called; don't rely on our caller to do it.
5729 (add_file): Remove call to init_misc_bunches.
5731 * mipsread.c: Only warn, don't error, if unknown symbol types.
5732 This keeps an old gdb from falling on its face if it sees newly
5733 extended symbol info. Rename init_misc_bunches.
5735 Fri Sep 7 22:58:15 1990 John Gilmore (gnu at cygint)
5737 * Merge in changes from Per Bothner for DECstations and other
5738 MIPS stuff. The rest is Bothner speaking:
5740 The next message is a merger of Alessando Forin's mips port with
5741 mine. I've tried to use my good if biased judgment to get
5742 the best of both. It *does* need testing.
5744 Some of the changes are general, *not* mips-specific.
5747 Didn't believe in little-endian bit order.
5748 There are still inconsistencies about whether flags
5749 like BITS_BIG_ENDIAN are integer (#if ...) or
5750 boolean (#ifdef ...). I tried to paper over them.
5752 dbxread.c,coffread.c,mipsread.c,symtab.c,symtab.h:
5753 Moved some misc_function code that was common to
5754 {dbx,coff,mips}read.c to symtab.c.
5755 In the process, I think I cleaned things up a bit.
5756 At the same time, moved obsavestring and obconcat to symtab.c.
5759 Removed obsolete condense_addl_misc_bunches (use
5760 condense_misc_bunches(1) instead).
5763 Needed to include <sys/dir>, at least on DECstations.
5765 valops.c, mips-tdep.c, tm-mips.h:
5766 Added PUSH_ARGUMENTS macro to support funny argument-pushing
5767 conventions (when STACK_ALIGN is insufficient).
5768 Needed on mips, where doubles need 8-byte alignment,
5769 but ints only need 4.
5772 Removed cruft that was not being used.
5773 Merged in many fixes (most from Frank Yellin, fy@lucid.com).
5776 Print $ before register-names (I think that makes things a little
5778 Never print two instructions, even if one delays.
5779 Removed hex-disassemble set_cmd. (This is not mips-specific,
5780 so I think the argument is whether it is generally worthwhile or not.
5781 I'm inclined to think not, given how easy it is to
5782 convert between radixes in gdb.)
5785 This is basically Alessando's code.
5786 It doesn't use obstacks; I changed it to use obstacks
5787 in a few minor places where using malloc causes a
5788 memory leak. (Probably, more places could/should be changed.)
5789 I added record_misc_function where it was missing.
5790 In symbol_file_command and add_file_command, I tried
5791 to make the code consistent with more recent versions.
5792 Minor sylistic changes in parse_procedure.
5793 Make a .gdbinfo. psuedo-symbol point back to the real
5794 procedure symbol (using the isym field).
5797 This is basically from my port, but with a lot of details
5798 and a number of routines merged in from Alessando's version.
5799 I basically used my code "raw" backtrace (use heuristics
5800 from the actual code, rather than symbol table info) - though
5801 the idea is Alessandro's. I feel my code is a little cleaner
5802 here, particularly in being a little more flexible, such as being
5803 able to handle gcc-produced code (which it now can).
5804 It also doesn't do frame caching (which is not useful
5805 more recent gdb versions).
5806 I also used my code for push_/pop_dummy, more or less.
5807 I tried to incorporate AF's code for testing sigtramp
5808 while backtracing; I probably got it wrong.
5809 Added mips_print_register, which tries to scrunch as much
5810 information as possible on a screen...
5811 Removed the skip-prologue set_cmd. As with hex-disassemble (see
5812 under mips-pinsn.c), I don't see anything mips-specific here,
5813 and I don't see it being all that useful anyway.
5816 Added a $fp psuedo-reg distinct from $fp (nice for gcc).
5817 Use more register names (rather than hard-cases numbers).
5819 Thu Sep 6 18:33:15 1990 John Gilmore (gnu at cygint)
5821 * Hack up 3.90.11 changes:
5823 * Makefile.dist (depend): parameterize $(GCC).
5824 Add solib.c and solib.o.
5825 (readline): Fix vpath for both absolute or relative SRCDIR.
5827 * blockframe.c: Fix from Schaefer@asc.slb.com for shared libs.
5828 Also, let the part I didn't understand at least compile so
5829 I can test the rest. FIXME.
5831 * dbxread.c: Fix thinko using strcmp.
5832 (init_psymbol_list): declare static.
5833 (partial_symbol_file_open): Comment cleanups better, avoid
5834 cleaning up the string table since the caller will do that.
5835 Move the stat for mod time into symbol_file_command, temporarily.
5836 (There should be a mod time for each symbol file, eventually,
5837 to control its rereading. FIXME.)
5839 * infptrace.c (PT_WRITE_D): use same value as PT_WRITE_I for
5840 SunOS, which gives error for shared libs otherwise. (From
5841 Schaefer, probably FIXME needs work for portability.)
5843 * solib.c: Move #include "param.h" to work.
5844 Lowercase all the Uppercase Letters In the Messages.
5845 (find_solib): Clean up inferior_so_name for debug printouts.
5846 Allow no argument, to mean all shared libraries.
5848 * symmisc.c: include param.h to get CLEAR_SOLIB.
5850 Wed Sep 5 18:00:08 1990 John Gilmore (gnu at cygint)
5852 * Merge in Kingdon's changes from FSF: the diffs from 3.90.9
5853 to 3.90.11. ChangeLog entries below are from this.
5855 Wed Jun 13 09:17:39 1990 Jim Kingdon (kingdon at mole.ai.mit.edu)

5861 Tue Jun 12 16:15:26 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5865 * Makefile.dist (gdb.tar.Z): Change linking of config so it works.
5867 Thu Jun 7 16:22:27 EDT 1990 Jay Fenlason (hack@ai.mit.edu)
5869 * sparc-opcode.h Added single-operand version of rett.
5871 Mon Jun 4 18:12:31 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5873 * m-sparc.h (REG_STRUCT_HAS_ADDR, STRUCT_ARG_SYM_GARBAGE):
5874 Put parens around gcc_p in expansion.
5876 Thu May 24 15:44:51 1990 Jim Kingdon (kingdon at mole.ai.mit.edu)
5878 * utils.c (lines_to_list): Return 10 if lines_per_page == 0.
5880 Wed May 23 16:36:04 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5882 * Changes for Sun shared libraries:
5883 blockframe.c (find_pc_partial_function): If a non-text symbol
5884 is found, set *address = pc - FUNCTION_START_OFFSET.
5885 breakpoint.c (insert_breakpoints) [DISABLE_UNSETTABLE_BREAK]:
5886 Disable breakpoints instead of giving an error.
5887 source.c (select_source_symtab): Initialize cs_pst.
5888 symmisc.c: Call CLEAR_SOLIB if defined.
5889 symtab.h: Make text{low,high} CORE_ADDR not int.
5890 (psymtab): New field addr.
5892 dbxread.c: Move DECLARE_FILE_HEADERS outside functions.
5893 (record_misc_function): Give correct type for N_DATA symbols.
5894 (condense_misc_bunches): do "misc_function_count = j" regardless
5896 Take code which is shared between symbol_file_command and
5897 add_file_command and put it into partial_symbol_file_{open,read}.
5898 Split add_file_command into add_file_command and add_file.
5899 Make psymtab_to_symtab read in the string table if the file
5901 Two new parameters to read_dbx_symtab and start_psymtab.
5902 tm-sunos.h: New file.
5904 Tue May 22 17:43:03 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5906 * infcmd.c: Change cont_command to continue_command and "cont"
5909 Mon May 21 14:41:41 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5911 * breakpoint.c (enable_breakpoint): Get value of watchpoint.
5913 * defs.h [sparc]: Use <alloca.h> regardless of __GNUC__.
5915 * values.c (USE_STRUCT_CONVENTION): Check for structures of
5916 size 1,2,4,8 rather than size < 8.
5918 * dbxread.c (dbx_lookup_type): Do f->length *= 2 as many times
5919 as necessary, not just once.
5921 * sparc-opcode.h: Add a bunch of new opcodes which Sun as supports.
5923 Thu May 17 15:04:09 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5925 * {t,x}m-sun386.h, sun386-xdep.c, {x,t}config/sun386
5927 * tm-news.h: Add CALL_DUMMY_*.
5929 * tm-68k.h: Remove duplicate comment at FRAME_FIND_SAVED_REGS.
5931 * config.gdb: In list_host, list_target, use ${i}, not $i.
5933 Tue May 15 21:27:12 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5935 * source.c (find_source_lines) [BROKEN_LARGE_ALLOCA]: Use xmalloc.
5937 * sparc-opcode.h: Change all store floating-point state register
5938 instructions to have the right match & lose fields.
5940 Sat May 5 12:39:18 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5942 * Makefile.dist: Move -I${srcdir} to GLOBAL_CFLAGS and pass
5944 config.gdb: If srcdir != ., create readline directory and
5945 copy a makefile into it.
5947 * wait.h, infrun.c: Change WRETCODE to WEXITSTATUS for
5948 consistency with POSIX.
5950 * breakpoint.c (bpstat_stop_status): Disable watchpoint
5951 when we exit its exp_valid_block.
5953 Tue Sep 4 11:46:46 1990 John Gilmore (gnu at cygint)
5955 * Makefile.dist: Bump version to 3.91.3.
5957 * Clean up handling of breakpoint commands (somewhat).
5958 Prompted by Tiemann bug report "cont 10" doesn't work any more.
5960 inferior.h: Add breakpoint_proceeded to inferior status struct
5961 and globals; save it and restore it.
5962 (clear_breakpoint_commands): Cleanup, remove old #define.
5964 infrun.c (clear_proceed_status): Set breakpoint_proceeded.
5965 (save_inferior_status, restore_inferior_status): handle it also.
5966 (proceed): Remove earlier code that set breakpoint_proceeded.
5967 It is now set only in clear_proceed_status.
5968 (clear_proceed_status): Cleanup, use bpstat_clear rather
5969 than clear_breakpoint_commands. No callers need the stop_bpstat
5970 between clear_proceed_status and proceed.
5972 infcmd.c: Add breakpoint_proceeded definition and comment.
5973 (cont_command, jump_command, signal_command): Move call to
5974 clear_proceed_status right next to call to proceed.
5976 breakpoint.c (bpstat_do_actions): Avoid clobbering our
5977 caller's argument while running down the chain of breakpoints.
5978 Use new variable "breakpoint_proceeded" to determine when
5979 a command that it executes moves the inferior past the
5981 (bpstat_clear): Handle NULL argument.
5982 (bpstat_clear_actions): Avoid useless call to
5983 breakpoint_auto_delete.
5984 (delete_breakpoint): Clean up bpstat's that are pointing to
5985 the deleted breakpoint from the stop_bpstat chain.
5986 (breakpoint_auto_delete): Simplify.
5988 * Clean up handling of EOF, error on stdin, etc. This was
5989 prompted by a network problem that caused gdb to go into an
5990 infinite loop filling up its malloc'd memory.
5992 main.c (return_to_top_level): Cleanup: call bpstat_clear_actions,
5993 not clear_breakpoints_commands, which is now gone.
5994 (main): If command_loop returns (e.g. from EOF on stdin), do
5995 a quit_command (looping back to command_loop if quit_command
5996 doesn't really quit).
5997 (command_loop): check result from command_line_input and
5998 exit if it returns NULL, rather than passing the NULL to
6000 (gdb_readline): Free malloc'd result space before returning
6003 * utils.c (query): Handle C-d to mean "yes", just as if the
6004 input was not a terminal. Also avoid infinite loop if EOF
6005 occurs in mid-input-line before newline. This allows
6006 query to be used at EOF on stdin with reasonable results.
6008 * infrun.c (proceed): Set breakpoint_proceeded.
6010 * values.c (value_as_long): Avoid infinite recursion for enums.
6011 (_initialize_values): Fix typo in help msg (kingdon).
6013 * Makefile.dist (RL_LIB): Use RL_LIB_DEP for dependencies,
6014 RL_LIB for linking. This allows -lreadline for linking
6015 and nothing for dependencies, once readline is a real library.
6017 * config.gdb: Jim Kingdon: give useful error message if the
6018 host or target type is not recognized.
6020 * defs.h (alloca): SPARC <alloca.h> does not declare alloca,
6021 it just defines it. Dumb, but deal with it.
6023 * Jim Kingdon suggests:
6024 in xconfig/sun3os4, CFLAGS should be XM_CFLAGS.
6026 Wed Aug 29 18:03:27 1990 John Gilmore (gnu at cygint)
6028 * Makefile.dist (VERSION): Bump version # to 3.91.2.
6030 * Clean up Bothner's changes.
6032 * blockframe.c (clear_pc_function_cache): New function.
6033 * blockframe.c: remake cache_pc_function_* static.
6034 * dbxread.c (symbol_file_command): remove references to
6035 cache_pc_function_* variables.
6036 * dbxread.c (read_struct_type): Use VOFFSET_STATIC.
6037 * printcmd.c: Avoid kludging a global variable (addressprint)
6038 to avoid printing the address of a string twice. Instead,
6039 pass the format letter 's' down low enough that it can be seen
6040 to avoid this problem.
6041 (print_formatted): Pass format arg to value_print.
6042 (restore_addressprint): Remove function.
6043 (do_examine): Avoid hacking addressprint, cleanups and such.
6044 (print_frame_args): Add a comment to a Bothner change.
6045 * symtab.h: define VOFFSET_STATIC and use it instead of "-1".
6046 * symmisc.c (free_all_symtabs): Call clear_pc_function_cache
6047 to wipe out the values cached in blockframe.c.
6048 * symtab.c (find_method): Add comment saying how big you must
6049 allocate to be "big enough". Per being terse again.
6050 * valprint.c (val_print): Handle format letter "s" to print
6051 strings without addresses. Add comment to vtbl printing code
6052 which casts with wild abandon. Rearrange reference-printing
6054 @0xaddr: value (print w/addressprint)
6055 value (print w/~addressprint)
6056 @0xaddr (parameter lists w/addressprint)
6057 or nothing (parameter lists w/o addressprint)
6059 Tue Aug 28 10:47:18 1990 John Gilmore (gnu at cygint)
6061 * Merge more changes from Per Bothner:
6063 Gdb's handling of TYPE_CODE_REF was so counter-C++ (and otherwise
6064 annoying) that I tried to improve it. Here are my suggestions.
6066 These patches all attempt to handle TYPE_CODE_REF (as in C++) better.
6069 Do automatic de-reference when taking the address of a reference.
6071 Don't deref_ref when printing parameter lists.
6073 More attempts at treating refernences properly.
6075 In val_print, if deref_ref==0, don't print dangling " = ".
6077 Add COERCE_REF macro, which de-references an REF.
6079 * Merge changes from Per Bothner:
6081 * Fixed (Sony news)-specific configuration problems.
6082 * Fixed other problems with using vanilla pcc and libc (enum problems;
6083 assumption that vsprintf exists).
6084 * Some major speed-ups (finc_pc_partial_function now caches a match;
6085 parsing avoids duplicate symbol_lookup calls).
6086 * Changed handling of baseclasses (no longer use baseclasses field
6087 of struct type, use the first n_baseclasses fields instead).
6088 * Various minor changes/fixes, most C++-related.
6091 Cache the most previous match from find_pc_partial_function.
6092 (Save both low and high ends of matching function's pc range.)
6093 This speeds up the loop of infrun.c:wait_for_inferior quite
6094 a bit, and makes step/next commands much zippier.
6096 Added an enum->int cast (otherwise, some compilers barf).
6098 No longer set baseclass offset to 0, since multiple
6099 inheritance now mostly works.
6100 Added a number of casts, to shut up compiler warnings
6101 (after stabs where made enums, not ints).
6102 When discarding a symbol table (in symbol_file_command),
6103 must clear the cache introduced in blockframe.c.
6104 Don't convert $vtbl_ptr_type to vtbl any more.
6105 Get rid of TYPE_BASECLASEES and baseclass_vec (see also symtab.h).
6106 Mask off sign bit emitted by g++ for virtual table offset.
6107 Set voffset to -1 (not 1) for static member functions.
6109 Changed parsing/lexing of names to avoid doing symbol lookup twice
6110 (once when lexing to determine symbol class, once for real).
6111 Now only call symbol_lookup once. Fields of 'this' win especially big.
6113 Subpress printing addr twice in the case of 'x/s addr'.
6115 lookup_basetype_type is no longer used.
6116 Add find_methods as recursive helper function to decode_line_1.
6117 This allows multiple inheritance to work.
6118 Also, once one or more matches has been found, do not look in
6119 base-classes. (Baseclass methods would be overridden, anyway.)
6121 Removed baseclasses array in struct type.
6122 Instead of using baseclasses[i], use fields[i-1].
6123 Added virtual_field_bits[i] to indicate if the i'th baseclass is virtual.
6124 Changed sign convention of voffset (previous was inconsistent).
6126 Some macros (CALL_DUMMY and relatives) were missing. Put them back.
6128 Used to assume existence of vsprintf. Re-written to not need it
6129 if HAVE_VPRINTF is undefined.
6131 typecmp was too pessimistic. Made it less so.
6133 Don't print space after address.
6134 If vtable points to a misc symbol (with 0 offset), print it,
6135 since that indicates the actual class of the object.
6136 Changed ype_print_derivation_info to use new inheritance
6137 scheme (without baseclasses vector).
6139 In value_primitive_field, fixed some bugs left over from previous set of fixes.
6140 Also, changes needed because TYPE_BASECLASSES were removed.
6142 REGISTER_U_ADDR didn't work for PC. Rewrote to use an array.
6144 Tue Aug 21 20:08:54 1990 John Gilmore (gnu at cygint)
6147 If there is no path set, and the symbols don't indicate what directory
6148 a file was compiled in, look in the current directory. But either
6149 a path or a known compilation directory will prevent this.
6152 Three independent bug fixes:
6153 * Remove the #if 0 block that breaks some stuff.
6154 * SunOS 4.1 fixed the promoted-parameter-wrong-addr bug in Sun C;
6155 adapt gdb to either SunOS 4.0.* or 4.1.
6156 * MAX_OF_TYPE and MIN_OF_TYPE thinko. By tedg@sun, I think.
6159 Instantiate the class T when looking for methods in it. (Tiemann@sun)
6162 (type_print) Demangle the name being printed.
6163 (type_print_base) Handle botched demangling without coredump (tiemann).
6166 (check_stub_method): Document routine.
6167 (tiemann) fix bug for no-arg functions
6168 Avoid clobbering beyond end of malloc'd storage.
6169 Terminate the argument list properly.
6171 Sat Aug 18 01:29:59 1990 Per Bothner (bothner@cs.wisc.edu)
6173 * Changes merged by John Gilmore:
6176 In breakpoint_1, use new print_address_symbolic instead
6177 of find_pc_partial_function. (This forces use of assembler-level
6178 addresses, and avoids misleading non-mangled source-level names.)
6180 Generalize ansi argument such that -1 means skip arglist totally.
6181 Removed global variable print_ansi_qualifiers (which made
6182 code non-reentrant), in favor of extra explicit arguments
6183 to internal routines.
6185 Add new helper function print_address_symbolic.
6186 Use find_pc_misc_function instead of find_pc_partial_function
6187 (since we want assembler-level symbols here).
6189 Print unknown function as just "f (...)", not "f (...) (...)".
6190 Use new fputs_demangled explicitly.
6192 Fixed a typing violation (problem: value.h cannot be imported
6193 without renaming many variable in this file).
6194 lookup_symbol: If no matching misc_func, look for a C++-mangled name.
6195 decode_line_1: Moved forward some never-reached code.
6196 Made decode_line_2 skip function prologues correctly.
6198 fputs_filtered should not demangle by default.
6199 Add new fputs_demangled to demangle on demand..
6201 Change value_struct_elt to use value_primitive_field (using recursive
6202 utility function search_struct_field). This allows foo.bar to work
6203 for multiple inheritance (so far only for data fields).
6204 Change check_field in the same way (recursive helper function
6205 to support multiple inheritance).
6206 (Note: there are more of these problems that I haven't fixed.
6207 Any code that says TYPE_BASECLASS (t, 1) is probably wrong.)
6208 value_of_this: 'this' symbol name is now just "this", note "$this".
6210 Don't print static members.
6211 Avoid printing "members of <type>" if there are none.
6212 Simplified type_print_derivation_info by merging duplicate code.
6213 Remove useless blank lines in type_print_base (ptype command).
6215 Added declaration of new routine value_primitive_field.
6217 Added value_primitive_field which is generalized version of
6218 value_field that can handle multiple inheritance (non-zero offsets etc).
6219 Re-implemented value_field to call value_primitive_field.
6221 Fri Aug 17 23:33:44 1990 John Gilmore (gnu at cygint)
6223 * infcmd.c -- insert else to avoid 'delete env' coredump when you
6224 delete the whole environment. Karl Berry reported the bug.
6225 * source.c - fix openp to avoid //'s in filenames, which
6226 trigger an Emacs bug causing it to not be able to find files
6227 when running gdb in a window.
6228 * dbxread.c - zap the #if 0 that botches the add-file code.
6229 It seems to work a lot better without all the code commented out.
6231 Fri Jul 20 16:58:46 1990 John Gilmore (gnu at cygnus.com)
6233 * Merge Tiemann's and Ted Goldstein's changes, detailed below,
6236 Tue Jul 17 19:34:33 1990 Ted Goldstein (tedg at golem)
6238 * Makefile - added a ${CFLAGS} to a couple of entries,
6239 added remote-sa.sparc.c
6240 * added remote.sa-sparc.c, a modification of remote.c
6241 which conducts a dialog directly with the SparcStation prom.
6242 * breakpoint.c, infrun.c, sparcdep.c added
6243 remote_insert_breakpoint(), and remote_remove_breakpoint()
6244 to breakpoint.c instead of directly writing breakpoint instructions.
6245 * sparcdep.c on remote_debugging,there is no need
6246 to remove signle step breakpoint instructions.
6247 * main.c added "-epoch" flag and "int epoch_interface" to main.c
6249 * printcmd.c - epoch interface sends lisp expressions to open up
6250 epoch windows on inspection.
6251 * valprint.c - added arrayprint, and addressprint and made adding
6252 format controls easier
6253 * wait.h added a couple of undef's because we were getting
6254 complaints about WSTOPSIG and WTERMSIG begin redefined.
6257 Wed Jul 4 05:27:51 1990 Michael Tiemann (tiemann at masham)
6259 * symtab.c (decode_line_1): Add support for handling method stubs
6260 in the type information.
6262 Tue Jul 3 09:39:18 1990 Michael Tiemann (tiemann at masham)
6264 * values.c (baseclass_addr): Run loop from INDEX+1 to
6265 N_BASECLASSES; otherwise, we can still get into a loop.
6266 @@ This should be restructured to use a cleaner search strategy.
6268 Sun Jul 1 12:28:51 1990 Michael Tiemann (tiemann at masham)
6270 * dbxread.c (define_symbol,read_type): Grok GNU C++'s new
6271 abbreviation "Tt" for tags which have the same name as their
6274 Fri Jun 29 01:03:46 1990 Michael Tiemann (tiemann at masham)
6276 * symtab.c (list_symbols): add ability to set breakpoints on all
6277 the functions which match a particular regular expression.
6279 Tue Jun 26 04:26:29 1990 Michael Tiemann (tiemann at masham)
6281 * cplus-dem.c (cplus_demangle): New parameter ANSI says whether we
6282 should print ANSI qualifiers (such as `const' and `volatile').
6283 All callers changed to call with ANSI == 1, except from
6284 `check_method_stub', which uses old-style syntax.
6286 * symseg.h (struct fn_field): Remove unneccessary `args' field.
6287 * symtab.h (TYPE_FN_FIELD_ARGS): Redefined.
6289 * values.c (check_stub_method): New function.
6291 * cplus-dem.c (do_type): Handle "long long" (encoded as 'x').
6293 * dbxread.c (read_type): Handle new GNU C++ method type stubs.
6294 * valprint (type_print_base): Ditto.
6296 * symtab.c (gdb_mangle_typename): New function.
6298 Tue Jun 5 00:18:43 1990 Michael Tiemann (tiemann at gzilla)
6300 * breakpoint.c (catch_command): New function. Provides a
6301 mechanism to set breakpoints based on catch clauses.
6302 (disable_catch): Similar, but disables breakpoints on catch
6304 (delete_catch): Similar, but deleted breakpoints on catch clauses.
6306 Sun Jun 3 22:54:08 1990 Michael Tiemann (tiemann at gzilla)
6308 * blockframe.c (blockvector_for_pc): New function.
6309 * blockframe.c (block_for_pc): Changed to call
6310 `blockvector_for_pc' and get the block itself.
6312 * stack.c (catch_info): New function. Prints info about
6313 exceptions which can be caught in the current frame.
6314 * stack.c (print_frame_label_vars): New function. Similar to
6315 `print_frame_local_vars'.
6316 * stack.c (print_block_frame_labels): Prints out labels that are
6317 defined in this frame. These labels are exceptions that can be
6320 * dbxread.c: Updated to handle N_CATCH symtab types.
6322 Thu May 3 22:10:00 1990 Michael Tiemann (tiemann at teacake)
6324 * valprint.c (everywhere): TYPE_NAME (TYPE) no longer comes in the
6325 form "struct ..." for GNU C++. Don't flush any part of TYPE_NAME
6326 when printing the type.
6328 Wed May 2 22:43:04 1990 Michael Tiemann (tiemann at teacake)
6330 * valprint.c (val_print): Use `baseclass_addr' to access the
6331 baseclasses pointed to via the derived class object at VALADDR.
6333 * values.c (baseclass_addr): New function. Casts derived pointers
6334 to baseclass pointers taking virtual baseclasses and multiple
6335 inheritance into account.
6337 Sat May 5 12:39:18 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
6341 Fri May 4 12:12:55 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
6343 * breakpoint.c (watch_command, bpstat_stop_status): Deal with
6344 exp_valid_block field correctly.
6346 * infrun.c (wait_for_inferior): When checking "don't even think
6347 about breakpoints" if stop_signal == SIGTRAP && trap_expected,
6348 also check step_resume_breakpoint.
6349 Insert breakpoints and continue (not step) if
6350 step_resume_break_address != NULL, even if another_trap.
6351 If trap_expected and we enter sigtramp, then set up a
6353 If trap_expected is set when we hit the step_resume_break,
6355 When calling resume and trap_expected says tell resume to step
6356 (2 places), also check step_resume_break_address.
6358 * infrun.c (wait_for_inferior): Don't set
6359 prev_{pc,sp,func_{start,name}} before calling wait ().
6360 Do set them after exiting loop.
6361 Move their declarations outside functions.
6362 (start_inferior): Initialize them.
6364 Thu May 3 00:15:11 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
6366 * infrun.c (wait_for_inferior, after check for trap_expected > 1):
6367 Restore old code which distinguishes between trap_expected and
6368 running_in_shell, just make the latter take any non-TRAP signal,
6371 * values.c (allocate_value): Zero VALUE_OPTIMIZED_OUT flag.
6373 * Makefile.dist (pinsn.o): Use PINSN_CC to compile.
6374 xconfig/3b1 (CC,PINSN_CC): Define.
6376 * xconfig/altos, altos-dep.c: Rename altos-dep.c to altos-xdep.c.
6380 * breakpoint.c (bpstat_stop_status),
6381 infrun.c (wait_for_inferior) [SHIFT_INST_REGS]: New code.
6383 * param.h, tm-88k.h: Define ADDR_BITS_*.
6384 infcmd.c (jump_command, read_pc), infrun.c (wait_for_inferior),
6385 printcmd.c (do_one_display): Use them.
6387 * utils.c: Split #ifdef USG into a USG_UTILS and a QUEUE_MISSING.
6388 xm-88k.h: Define USG_UTILS.
6390 Wed May 2 00:05:33 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
6392 * printcmd.c (printf_command) [__INT_VARARGS_H]: New code.
6393 (printf_command): Add from_tty parameter.
6395 * valprint.c (value_print): Check VALUE_OPTIMIZED_OUT flag.
6397 * value.h: Add optimized_out field and change lazy field to
6398 char. Add macro VALUE_OPTIMIZED_OUT.
6400 * i386-pinsn.c: Change from Eirik Fuller to write to stream directly
6401 instead of stuffing things in buffers (oappend, etc).
6403 * breakpoint.c (bpstat_do_actions): If *BSP is set to NULL by
6404 execute_command, exit both loops.
6406 * Makefile.dist: Don't set TARGET_ARCH. Add .c.o rule.
6408 Tue May 1 17:07:23 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
