5 * infrun.c: Remove tdesc-related code.
6 * m88k-tdep.c (frame_chain_combine, init_frame_pc): Remove copies
8 * tm-m88k.h: New file, common to all Moto 88k target configs.
9 Derived from tm-delta88.h.
10 * tm-delta88.h: Use it.
11 * xm-m88k.h: Common file for 88K hosts. Remove obsolete stuff.
12 * xm-delta88.h: Use it.
13 * tm-*.h: Remove FRAME_CHAIN_COMBINE macros, since all are
15 * coffread.c: Remove tdesc stuff.
17 Mon Nov 18 13:51:37 1991 Per Bothner (bothner at cygnus.com)
19 * source.c (open_source_file): If openp fails, try again
20 using just the base (non-directory) part of the filename.
21 This solves various annoying problems, such as when the
22 source was compiled with an absolute pathname - and the
23 source files have moved. Or if the source was compiled
24 using a relative pathname, it can be more convenient
25 to just specific the source directory to the dir command.
27 Mon Nov 18 00:04:41 1991 Fred Fish (fnf at cygnus.com)
29 * cplus-dem.c (munge_function_name): Add missing third arg to
30 instance of call to do_type().

38 * symtab.h (struct type): Moved C++-specific fields into new type
39 `struct cplus_struct_type'. Now takes 10% less memory. Many
41 * symtab.c (init_type): Don't set fields belonging to
42 TYPE_CPLUS_SPECIFIC unless TYPE is TYPE_CODE_STRUCT.
43 * buildsym.c (read_type): Allocate TYPE_CPLUS_SPECIFIC for
45 (read_struct_type): Ditto. Also, add comments about how we can
46 deduce TYPE_VPTR_FIELDNO from inheritance info and fieldname info.
47 * coffread.c (decode_base_type): Allocate TYPE_CPLUS_SPECIFIC for
49 (read_struct_type): Ditto.
50 * dwarfread.c (struct_type): Ditto.

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

103 Motorola 88000 port without tears, I mean without tdescs.
105 * m88k-tdep.c: Blow away all tdesc stuff.
106 Provide functions for all the frame-related macros in

108 (examine_prologue, frame_find_saved_regs, skip_prologue): borrow
109 from i960-tdep.c and adapt to the function prologues on the 88k.
110 (read_next_frame_reg): Borrow from mips-tdep.c.
111 FIXME: frame_locals_address should go away.
113 * tm-delta88.h: Dump all the tdesc stuff.
114 Macros for all frame-related stuff call fns of same name.
115 Remove duplicated definitions. FP_REGNUM becomes same as
118 * xm-88k.h: Eliminate lots of library dependencies, now handled
119 in libiberty. Eliminate KDB nonsupport.
121 * doc/gdbint.texinfo: Add rudiments on frames. FIXME, add more.
124 * stack.c (frame_info): Mark frameless functions.
125 Print locals address (FIXME, remove if same).
126 * blockframe.c: Comment changes, FIXME after.
127 * coffread.c: Even without TDESC, need to zap "@" symbols.

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

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

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

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

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

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

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

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

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

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

991 (process_coff_symbol): #if 0'd for functions and params as above.
992 (read_enum_type): Recognize Modula-2 BOOLEAN.

1065 Tue Sep 17 08:37:41 1991 John Gilmore (gnu at cygint.cygnus.com)
1067 Add Andrew Beers' changes for Modula-2 support. His ChangeLog
1068 entries are enclosed herein. Not all of these changes
1069 have been merged into the master GDB sources -- check the
1070 ChangeLog above here for the merge log.
1072 Mon Jun 3 17:05:45 EDT 1991
1074 m2-exp.y Created. Tested outside of GDB for a few days. Proper
1075 operators were added, C specific operators and tokens
1076 removed. yylex() revamped to some extent. Still things
1077 missing from the grammar, such as sets.
1078 Tested for two weeks in GDB v3.5.
1080 Tue Jun 11 17:23:48 EDT 1991
1082 m2-exp.y Added boolean constants TRUE and FALSE to the grammar
1083 so they are built-in. Sort of a hack.
1085 Fri Jun 14 12:53:51 EDT 1991
1087 m2-exp.y Added range checking for numeric constants. Any numeric
1088 constant is assumed to be of builtin type INTEGER unless:
1089 (1) it is octal or hexadecimal, in which case it is a
1090 CARDINAL; (2) it is too big to fit into an INTEGER, in
1091 which case it is a CARDINAL.
1092 eval.c Added simple range checking for +, -, and * on integers.
1093 Doesn't work very well for *, since 6 * 1,000,000,000 =
1094 1,705,032,704, which fails the simple test of result >=
1095 first_operand, no matter in what order the operands are.
1097 Tue Jun 18 14:11:30 EDT 1991
1099 Broke the parser into parts, one containing the C grammar and the other
1100 containing code to be shared by all of the grammars.
1102 The following files no longer exist:
1107 The following files were added:
1109 c-exp.y (The C grammar)
1110 m2-exp.y (The Modula-2 grammar)
1111 parser-code.c (Code that is shared by the above grammar)
1115 Makefile.dist Changed to reflect the above dependencies. NOTE: It is
1116 now necessary to use the Bison compiler compiler, since it
1117 will generate function/variable prefixes other than yy.
1119 Tue Jun 18 16:47:49 EDT 1991
1121 symtab.[ch] Added the external variable working_lang, than holds the
1122 value of the current working language.
1123 Added the ennumerated type language_mode, with the values
1124 language_auto and language_manual, the former meaning that
1125 GDB sets working_lang as needed, and the latter meaning
1126 that the value of working_lang is totally under user
1128 symtab.[ch] Added the Modula-2 pervasive types INTEGER, CARDINAL,
1129 REAL, BOOLEAN and CHAR. Also added the type codes
1130 TYPE_CODE_BOOL and TYPE_CODE_CHAR.
1131 utils.c Added set_language_command and show_language_command to
1132 implement the GDB support commands "set language" and
1134 expression.h A number of identifiers were added to the type exp_opcode
1135 to facilitate Modula-2 builtin functions, integer
1136 division, and array indexing.
1138 Wed Jun 19 13:25:58 EDT 1991
1140 language.h Added the macro STRICT_TYPE, which evaluates to non-zero
1141 if the language specified by working_lang requires the use
1142 of strict typing of expressions. Eventually, even this
1143 will be able to be changed by the user.
1144 Added the macro RANGE_CHECK, which evaluates to non-zero
1145 if the language specified by working_lang requires the
1146 checking of a value against the domain of its type.
1147 Eventually, even this will be able to be changed by the
1149 language.[ch] Predicates involving types (simple_type, ordered_type,
1150 same_type, integral_type, numeric_type, character_type,
1151 boolean_type, float_type) are added. These predicates are
1152 based on the current value of working_lang, and are handy
1155 Wed Jun 19 15:39:34 EDT 1991
1157 eval.c Added the function type_array_rank which computes the rank
1159 valarith.c Added the funtion value_bool, which when given a integer
1160 value.h value (ie. struct value *) as an argument, it returns a
1161 boolean value (ie. struct value *) true if that integer
1162 is non-zero, and a boolean value false otherwise.
1163 valprint.c Added cases for TYPE_CODE_BOOL, so Modula-2 BOOLEAN values
1164 will print out properly.
1166 Wed Jun 19 16:36:34 EDT 1991
1168 valops.c Added the function value_capitalize, which returns it
1169 value.h argument capitalized if its argument is a lowercase
1170 letter, or the argument unchanged if its argument is not a
1172 valarith.c Added the function range_check_p, which returns non-zero
1173 value.h if its value argument is between the integral bounds upper
1175 Added the function range_check_enum_p, which makes sure
1176 that its value argument is a valid member of the domain of
1178 Added the function range_check_range_p, which makes sure
1179 its value argument lies between the upper and lower bounds
1180 of its type argument, which must be a ranged type.
1181 Added the function check_array_index, which range and type
1182 checks an index of an array.
1183 Added the function value_multi_subscript, which computes
1184 array[idx1,idx2...idxN], given a value array and an array
1185 of values representing indicies.
1186 values.c Changed value_from_long to work with TYPE_CODE_CHAR and
1187 unpack_long to work with TYPE_CODE_BOOL and
1190 Wed Jun 19 18:04:08 EDT 1991
1192 symtab.c Stored pervasive types in a structure and make
1193 lookup_pervasive_type() a lookup function that was based
1194 on working_lang. If lookup_pervasive_type() returned
1195 non-zero, then that value was returned (a fix, since
1196 before it simply wouldn't return the pervasive type.)
1197 language.h Added the macro CAST_IS_CONVERSION, which evaluates to
1198 non-zero if the language specified by working_lang means
1199 "conversion" when it says "cast".
1200 valops.c Added the function value_real_cast(), which performs a
1201 value.h *cast*, not a *conversion*, which is what value_cast()
1202 does when it can. In particular,
1203 value_cast(<float_type>,4) = 4.0, while
1204 value_real_cast(<float_type>,4) = some mess.
1205 eval.c Modula-2 builtin functions implemented: ABS, CAP, CHR,
1206 parser-code.c FLOAT, HIGH, MAX, MIN, ODD, ORD, TRUNC, and VAL.
1207 expression.h Added macros MAX_OF_TYPE and MIN_OF_TYPE to work with MAX
1208 and MIN on integral types. *NOTE*: These are currently
1209 hardcoded to work only if there are 8 bits per storage
1211 eval.c Made logical functions call value_bool to return a
1212 properly typed boolean value, based on working_lang.
1214 Thu Jun 20 11:55:27 EDT 1991
1216 valprint.c Types now print out in a Modula-2 fashion. This works for
1217 the cases when the type is printed out step-by-step, that
1218 is, it doesn't work when the name of a structured type
1219 (which includes the keyword "struct", etc.) is simply
1221 FIXME: Perhaps this is bad. Parts of it seem to kludgey,
1222 since type specifications in C and Modula-2 are very
1223 different. The C printing of a type is very recursive,
1224 whereas in Modula-2 it is generally very simple. C has
1225 type prefixes and suffixes, which have no real analogue in
1226 Modula-2. Maybe type_print() should call a language
1227 specific type printer. This is also advantageous if we
1228 compile GDB to exclude some of the languages. We'll just
1229 leave those functions out.
1231 Thu Jun 20 16:57:10 EDT 1991
1233 dbxread.c When reading the complete symbol table in (via
1234 psymtab_to_symtab()), the number and types of function
1235 arguments are added to a function type. define_symbol()
1236 calls add_param_to_type() to accomplish this.
1237 Assumption: when we come across a function definition
1238 (N_FUN symbol with an 'f' or 'F' in the name), its
1239 arguments will appear before another function definition.
1240 When a function is found, a pointer to its type is placed
1241 in the global in_function_type. Changes that
1242 add_param_to_type() makes are to this global.
1243 valprint.c The type of a function now includes (for Modula-2) the
1244 types of its parameters.
1245 eval.c Type checking and a check for the proper number of
1246 arguments is now done for function calls. Not sure of the
1247 impact this has on C++ member function yet.
1249 Thu Jun 20 19:58:48 EDT 1991
1251 valprint.c Rewrote the type printer. Broke it into two language
1252 specific parts, adding the functions type_print_m2() and
1254 An unfortunate consequence is this: if you debugging a C
1255 program in Modula-2 mode (why?), info types does not work
1256 well with regular expressions, since the types are printed
1257 out in Modula-2 terminology, but stored in C terminology.
1258 language.[ch] Added the functions new_type_last(), type_keyword(), and
1259 type_sep() to aid in the printing of typedefs.
1260 symtab.c Made the printing of typedefs as language independent as
1261 possible through calls to new_type_last(), type_keyword(),
1264 Fri Jun 21 11:50:26 EDT 1991
1266 dbxread.c Check all incoming ennumerated types. If it looks like
1267 Modula-2's BOOLEAN type, then change the type_code of the
1268 type to TYPE_CODE_BOOL so we can process it as a boolean
1270 valprint.c Replaced some of the 0x%x with calls to sprintf and
1271 hexformat() in val_print().
1272 language.[ch] Added the function hex_to_string(), which converts its
1273 integral argument to a hexadecimal number (format is
1274 language based) and returns the result as a string.
1276 Mon Jun 24 12:25:07 EDT 1991
1278 valprint.c Some functions call type_print_1() directly, instead of
1279 value.h using type_print(), so they can specify where (column) to
1280 print things. Since type_print() takes care of language
1281 dependence, that needs to be called first. Added a
1282 parameter depth to type_print() (so it is now like
1283 type_print_1). Changed type_print to type_print_at, and
1284 made type_print a macro that passes a depth argument of
1286 symmisc.c Changed all calls to type_print_1 to calls to
1288 Makefile.dist Made it possible to build GDB for a specific set of
1289 depend languages. Do this by passing a definition for the macro
1290 LANGS to make. LANGS should be a string containing a
1291 space-separated list of language names (ie. LANGS="c m2").
1292 The default is to build all languages. Note that grammar
1293 files must follow the naming convention of <lang>-exp.y.
1294 gdb.lang This holds the current value of the LANGS macro. It is
1295 examined every time make is called, and is updated if
1297 eval.c Added #ifdef _LANG_<lang> to these files.
1298 expread.c Still need to add them to dbxread.c and coffread.c.
1306 Mon Jun 24 16:33:11 EDT 1991
1308 language.[ch] Added the functions hexformat_pre() and
1309 hex_to_string_pre(), which take a prefix argument to
1310 include in the format string. Thus, hexformat_pre("08") will
1311 return "0x08x" (if the working language is language_c).
1312 Made hexformat() and hex_to_string() calls to the above
1313 with "" as the prefix argument.
1315 am29k-pinsn.c, arm-pinsn.c, breakpoint.c, convex-tdep.c, exec.c, core.c,
1316 dbxread.c, i386-pinsn.c, i386-stub.c, i386-xdep.c, i960-pinsn.c,
1317 infcmd.c, inflow.c, m68k-pinsn.c, m68k-stub.c, m88k-pinsn.c,
1318 mips-pinsn.c, mips-tdep.c, ns32k-pinsn.c, printcmd.c, pyr-pinsn.c,
1319 pyr-tdep.c, pyr-xdep.c, remote-vx.c, remote.c, solib.c, source.c,
1320 stack.c, sun386-xdep.c, symfile.c, symm-xdep.c, symmisc.c, tahoe-pinsn.c,
1321 valprint.c, vax-pinsn.c
1323 Changed all occurences of 0x%[0-9]*l*x in printf format strings to
1324 calls to hexformat() and hex_to_string(). Format strings without
1325 the leading "0x" were ignored.
1327 depend Updated to take the above into account.
1330 Tue Jun 25 15:27:18 EDT 1991
1332 symtab.h Added the types range_mode_t, range_check_t, type_mode_t,
1333 and type_check_t to keep track of the current state of
1334 range and type checking.
1335 main.c Added the variables range_mode, range_check, type_mode,
1336 and type_check to record the current state of range and
1337 type checking. Added initialization code to main().
1338 language.h Changed the macros STRICT_TYPE and RANGE_CHECK to examine
1339 the above variables.
1342 Tue Jun 25 17:57:08 EDT 1991
1344 dbxread.c process_one_symbol() updates the variable (enum language)
1345 source_lang based on the extension of the filename
1346 contained in the N_SO sybmol that started this symtab.
1347 When end_symtab() is called, the value of source_lang is
1348 put into the language field.
1349 stack.c select_frame() sets working_lang (and possibly type_check
1350 and range_check) to the language field of the symtab
1351 associated with the frame that is selected if working_mode
1352 is language_auto. If working_mode is language_manual, a
1353 warning is printed and working_lang is not set.
1354 language.c Added the function set_type_range(), which sets the value of
1355 type_check and range_check (if their modes call for
1356 automatic setting) based on the current value of
1357 working_lang. A non-zero argument will cause the current
1358 settings to be output.
1361 Wed Jun 26 14:51:40 EDT 1991
1363 eval.c Added range checks on assignment.
1364 m2-exp.y Added the grammar for sets to the language. Currently,
1365 these do not do anything except print an error message.
1367 Wed Jun 26 17:01:04 EDT 1991
1369 m2-exp.y Added the ability for parse_number() to parse negative
1370 numbers. A global flag is set upon encountering a unary
1371 minus. This was done to make, for example, 1 parse as a
1372 CARDINAL, and not as an integer, per Wirth's examples in
1373 Programming in Modula-2 ed.4.
1374 valprint.c Added support for "set radix 2" by then setting
1375 output_format to 't'.
1376 eval.c Implemented range checking on subrange types. Added calls
1377 to range_check_range_p for BINOP_ASSIGN and BINOP_VAL.
1378 Implemented MIN and MAX for ennumerated types. The
1379 minimum value of an ennumerated type is defined by Wirth
1380 as the first identifier, and the maximum as the last.
1381 m2-exp.y Made octal numbers ending with "B" be characters and those
1382 ending with "C" be numbers, per Wirth's book. (p. 34)
1384 Thu Jun 27 14:11:52 EDT 1991
1386 stack.c select_frame() now only sets working_lang, it does not
1387 notify the user. If working_mode is language_manual, then
1388 a warning is issued once.
1389 main.c At the end of each call to execute_command(), working_lang
1390 is checked against the local static (enum language)
1391 current. If they differ and working_mode is
1392 language_auto, the new settings of language, type and
1393 range checking are printed out.
1394 stack.c Modified frame_info() to include the language of the
1395 current frame in the output of "info frame".
1396 language.[ch] Added the function language_str() which returns the name
1397 of the current language.
1399 Fri Jun 28 15:33:14 EDT 1991
1401 m2-exp.y Added the built-in procedures INC, INCL, DEC, and DECL to
1402 the language. INCL and DECL currently cause an error,
1403 since sets are not implemented yet. INC and DEC are
1404 implemented as PREINCREMENT/PREDECREMENT with one
1405 argument, and as ASSIGN_MODIFY with two arguments.
1406 eval.c Added type checking to the above cases.
1407 value.h Added not_lval_constant to the lval_type ennumerated type.
1408 not_lval_constant means that the value is a constant
1409 value; that is 3 or 'a' or TRUE, not as in a constant
1410 identifier. This is used to help coerce numbers such as 3
1411 to either signed or unsigned numbers.
1412 valops.c Added the function value_coerce_constants() which coerces
1413 constant integers as following: if one is a constant and
1414 the other is not, the constant's type is set to the type
1415 of the other argument. If both are constants and one is
1416 signed, the other is converted to a signed constant.
1418 Sat Jun 29 17:26:29 EDT 1991
1420 valarith.c Added a better range checker. It now checks range
1421 (successfully) on integral operations [+-] (signed and
1422 unsigned) for any C sized type. Still does not work well
1423 for multiplication.)
1424 int_in_size() returns an integer that is coerced to fit into
1425 specified number of bytes.
1427 Mon Jul 1 13:04:14 EDT 1991
1429 language.[ch] Added the function binop_result_type(), which returns the
1430 builtin (struct type *) type that would be the result of a
1431 binop on the two values V1 and V2.
1433 Wed Jul 3 19:22:53 EDT 1991
1435 source.c Extended source_info() to include the source language in
1436 the output from "info source".
1438 Fri Jul 5 13:48:52 EDT 1991
1440 utils.c Moved the support functions for the GDB set/show commands
1441 dealing with language into language.c.
1442 language.c Added the function language_info(), which displays info
1443 about the current working language, type and range check
1444 settings. Called via the GDB command "info language".
1445 Added an initialization routine _initialize_language(),
1446 that sets defaults for the language, type and range
1447 variables and sets up the new GDB commands.
1448 main.c Language setup moved to language.c.
1451 Mon Jul 8 10:10:22 EDT 1991
1453 valarith.c Debugged the range checker for arithmetic. Still does not
1454 work for multiplication very well.
1456 Mon Jul 8 12:40:37 EDT 1991
1458 language.[ch] Added the function value_true() which returns non-zero if
1459 its argument represents a boolean true value.
1460 breakpoint.c Changed breakpoint_cond_eval() to call value_true() to
1461 check the truth of an expression.
1463 Thu Jul 11 12:51:34 EDT 1991
1465 language.[ch] Added the predicate structured_type(), which returns
1466 non-zero if the argument is a structured type.
1467 Added the predicate pointer_type(), which returns non-zero
1468 if the argument is a pointer type.
1469 eval.c Added the ability to do addition and substraction on
1470 pointers and integers. This case simply bypasses the
1473 Thu Jul 11 14:41:42 EDT 1991
1476 Added the symbol N_DEFD (0x4a) which is a definition
1477 module dependency that is used by the GNU Modula-2
1478 compiler and the linker. It is not important to GDB,
1479 except that [dbx|coff|mips]read.c should ignore these
1482 Fri Jul 12 16:07:00 EDT 1991
1484 valprint.c Changed the TYPE_LENGTH(type) >= 0 to TYPE_LENGTH(type) >
1485 0 in val_print(). Also added statements to the else part
1486 to coerce type (argument to val_print) to a pointer type
1487 if it is an "array of unspecified length".
1488 valops.c Added the function value_m2_string(), which returns a
1489 (value) value which is a constant string, whose type is
1490 (ARRAY [0..n] OF CHAR). The length field of the type
1491 structure is set to zero, so it will be interpreted as an
1492 "array of unspecified length".
1493 stack.c Moved the language/frame mismatch check to
1494 main.c:execute_command().
1495 main.c The working language is recorded each time
1496 execute_command() is executed. If working lang has
1497 changed during its execution, then the new
1498 language/type/range info is printed out for the user. If
1499 the working language does not match the language of the
1500 frame, a warning is issued.
1502 Sat Jul 13 16:16:39 EDT 1991
1504 eval.c Moved all the type-checking stuff for operators to
1505 language.[ch] language.c. This is so we can keep language-specific
1506 stuff (like for what type operators are defined) in
1508 language.[ch] Added the function binop_type_check(), which checks to see
1509 if its two (value) arguments are type-compatible with its
1510 opcode argument. The opcode should represent an operation
1511 involving an operator. Also added the macro function
1512 unop_type_check, which calls binop_type_check with a
1513 NULL second argument.
1514 expprint.c Added Modula-2 operators to the op_print_tab, so info
1515 expression.h break works correctly. Also added "op_string", which
1516 returns the string corresponding to the (enum exp_opcode)
1517 opcode that is its argument.
1520 Sat Jul 13 18:26:18 EDT 1991
1522 coffread.c Added code to record the type of function arguments with
1523 each paricular function. Code is very similar to that
1525 dbxread.c Moved add_param_to_type() to symtab.c
1526 symtab.[ch] Added function add_param_to_type() from dbxread.c
1528 *** NOTE: The above additions have not been tested.
1530 Mon Jul 15 12:50:47 EDT 1991
1532 langauge.[ch] Added the functions type_error and range_error, which work
1533 like error() except if the type/range mode is set to
1534 *_mode_warn, then they do not do a return_to_top_level(),
1535 but merely print a warning.
1536 Also changed [set|show]_[type|range]_command() to support
1537 the new "warn" feature.
1539 Thu Jul 18 17:50:54 EDT 1991
1541 mipsread.c Added code to record the type of function arguments with
1542 each particular function. Code is very similar to that
1545 *** NOTE: The above additions have not been tested.
1547 Fri Jul 19 11:19:10 EDT 1991
1549 defs.h Added macros MAX_OF_SIZE, MIN_OF_SIZE, UMAX_OF_SIZE, and
1550 UMIN_OF_SIZE, which when given a size of a numeric type,
1551 return the maximum and minimum value it can hold. UMAX...
1552 and UMIN... return the result for unsigned types.
1553 symtab.h Added the macros MAX_OF_TYPE and MIN_OF_TYPE to operate on
1554 struct types. They call above macros.
1555 dbxread.c Renamed the MAX and MIN_OF_TYPE macros to ..._OF_CTYPE to
1556 avoid a name conlict with the above.
1557 c-exp.y Added range checking on numeric constants in
1558 parse_number() for completeness.
1559 valarith.c Made binop_user_defined_p() and unop_user_defined_p()
1560 return 0 if working_lang is not language_c.
1562 Thu Aug 8 14:17:22 EDT 1991
1566 breakpoint.c Documentation strings of some commands changed to
1567 eliminate the references to the C language where
1570 Tue Aug 13 15:48:03 EDT 1991
1572 m2-exp.y Added qualified identifiers to the grammar. The semantics
1573 are slightly different from those of the GDB operator ::
1575 m2-exp.y Added a rule to each grammar of the form: start ::= exp |
1576 type_exp, where type_exp is any valid type expression.
1578 eval.c Added the opcode OP_TYPE, and an error case in eval.c.
1579 printcmd.c Modified ptype_command() so it actually parses the input
1580 (necessary for type expressions with scope qualifiers).
1581 Added the function ptype_eval() which expects an
1582 expression composed of one OP_TYPE element.
1583 *.[ch] Replaced all occurences of parse_c_expression with
1585 *.[ch] Replaced all occurences of parse_c_1 with parse_exp_1
1587 [End of ChangeLog entries from Andrew Beers for Modula-2 support.]
1589 Mon Sep 16 17:19:46 1991 John Gilmore (gnu at cygnus.com)
1591 Small fixes from Peter Schauer:
1593 * infrun.c (child_attach): Lint.
1594 * solib.c (find_solib): Handle shared libs version 2.
1596 Small fixes from David Wood:
1598 * xm-ultra3.h (SYS_SIGLIST_MISSING): Typo.
1602 * remote-vx.c: Move <stdio.h> to top, for FILE. Fix from
1603 John S <basrai%kanga.dnet@c3po.sm-alc.af.mil>.
1605 * utils.c (wrap_here): Avoid wrap action of fputs_filtered if
1606 chars_per_line is at maximum (user typed `set width 0'). Fix
1607 from Andreas Schwab <schwab@ls5.informatik.uni-dortmund.de>.
1609 Tue Sep 17 17:31:04 1991 Stu Grossman (grossman at cygnus.com)
1611 * coredep.c: include ptrace.h where necessary.
1612 * mipsread.c(parse_lines): fix unsigned char problem that was
1613 messing up line numbers on SGI's and possibly other MIPS based
1615 * infrun.c (child_create_inferior): use better test to check
1616 return val from setpgrp().
1617 * tm-irix3.h, xm-irix3.h, tconfig/irix3, xconfig/irix3: add these
1618 for sgi/irix support.
1620 Wed Sep 18 04:33:31 1991 Per Bothner (bothner at cygnus.com)
1622 * mipsread.c (parse_symbol): Put non-static procedures
1623 in the global block.
1625 Fri Sep 13 00:14:52 1991 John Gilmore (gnu at cygnus.com)
1627 Patch together `text_start' and `text_end' for 29K port.
1629 * exec.c (exec_command): If NEED_TEXT_START_END, define the
1630 variables and set them based on the exec file.
1631 * am29k-tdep.c: declare text_start.
1632 * valops.c (call_function_by_hand): declare text_end.
1634 * inferior.h: Eliminate CANNOT_EXECUTE_STACK in favor of
1635 defining CALL_DUMMY_LOCATION as BEFORE_TEXT_END. This is
1636 because machines that do this will also have to know to
1637 set NEED_TEXT_START_END. Besides, it was a redundant way to
1639 * tm-29k.h, tm-convex.h, tm-np1.h: Eliminate
1640 CANNOT_EXECUTE_STACK, define CALL_DUMMY_LOCATION and
1641 NEED_TEXT_START_END.
1643 Thu Sep 12 00:22:24 1991 John Gilmore (gnu at cygint.cygnus.com)
1645 AMD 29000 changes from David Wood <wood@david.ultra.nyu.edu>:
1647 * Makefile.in (CLIBS): Put XM_CLIBS and TM_CLIBS at end.
1648 Pass MUNCH_DEFINE to munch whenever we run it.
1649 * am29k-pinsn.c (print_insn): Handle NOP specially. Avoid %#x
1650 format string; use 0x%x instead.
1651 * am29k-tdep.c: Use DUMMY_SAVE_GREGS and RETURN_REGNUM.
1652 * ultra-xdep.c, xm-ultra.h: New files for Ultracomputer host system.
1653 * xm-rtbsd.h: New host support for RT/PC running BSD Unix.
1654 * inflow.c: Handle `short' process group IDs.
1655 * infptrace.c (fetch_register): Support CANNOT_FETCH_REGISTER,
1656 and check for ptrace errors.
1657 * coffread.c (SDB_REG_TO_REGNUM): Define if not already.
1658 (coff_symfile_init): Initialize text_bfd_scnum.
1659 (read_coff_symtab): Use it to find the text [and absolute?] sections.
1660 * ../config.sub: Add vendor nyu and os "sym[1-9]*".
1661 * configure.in: Add hosts rtpc-*-* and a29k-*-*.
1662 Merge target arm case with other "easy" cases. Add target
1663 cases a29k-*-none (rehack of am29k), a29k-*-kern (remote to
1664 Ultracomputer kernel), and a29k-*-sym1 (ultracomputer OS's user
1666 * minimon.h, remote-adapt.c, remote-mm.c: Add.
1667 * munch: Cope with RT/PC putting fns in data segment.
1668 Restore ability to override `nm' by specifying MUNCH_NM.
1669 * xconfig/rtbsd, xconfig/ultra3: New host systems.
1670 * tconfig/a29k: Rename from tconfig/am29k. Add remote-mm
1671 and remote-adapt. Remove encapsulated coff #define's (the
1672 support should go in BFD, and gdb shouldn't know or care).
1673 * tconfig/a29k-kern: Same, but for remote kernel debugging.
1674 * tconfig/ultra3: For debugging user processes on Ultra3/Sym1.
1675 * tm-29k.h: Update BADMAG (though it should go away).
1676 Allow the register definitions to be overridden in another
1677 tm-file. Fix SR_REGNUM. Add a mess of _REGNUM's. Separate
1678 RETURN_REGNUM from GR96_REGNUM and DUMMY_SAVE_GREGS from
1679 DUMMY_SAVE_GR96, for handling kernel calling conventions
1680 that use GR64+ rather than GR96+.
1681 * tm-ultra3.h: New file, for use on Ultra3 Unix as well as for
1682 remote debugging of Ultra3 kernel. Includes tm-29k.h and
1683 overrides various things.
1685 * remote-mm.c (mm_attach, mm_wait): Handle attach like
1686 child_attach does, making a clean stop in the newly attached
1688 * remote-eb.c: Lint.
1690 * coffread.c: Make coffread independent of any particular
1691 variant of COFF. Avoid #include-ing any particular one except
1692 internalcoff.h. BFD now passes key values for symbol reading
1693 as part of its coff_data structure (LINESZ, SYMESZ, AUXESZ,
1694 and the symbol masks and shifts); use them.
1695 Remove obsolete end_of_text_addr.
1697 * exec.c: Remove unused include files.
1699 Wed Sep 11 19:38:44 1991 John Gilmore (gnu at cygint.cygnus.com)
1701 * Makefile.in (documentation targets): Pass $(M4).
1702 Bugfix from eggert@twinsun.com (Paul Eggert).
1704 * stack.c (down_silently_command): Check for stack existence.
1706 Tue Sep 10 23:08:29 1991 John Gilmore (gnu at cygint.cygnus.com)
1708 * Makefile.in (VERSION): Update to 4.0.3.
1710 Tue Sep 10 09:19:29 1991 John Gilmore (gnu at cygint.cygnus.com)
1712 * core.c (core_file_command): Print frame at coredump with
1713 its level number, by calling print_stack_frame.
1714 * frame.h: Add selected_frame_level, print_stack_frame.
1715 * frame.h, stack.c: Remove print_sel_frame, print_selected_frame.
1716 * convex-tdep.c, convex-xdep.c, infcmd.c, inflow.c, infrun.c:
1717 Change print_sel_frame and print_selected_frame callers to
1720 * dbxread.c (read_ofile_symtab): Avoid empty else clause.
1721 * symfile.c (free_named_symtabs): Ditto.
1722 * main.c (main): wrap_here needs an arg.
1723 * solib.c (find_solib): Avoid memory access if _DYNAMIC is zero.
1724 (solib_add): Avoid noise.
1725 (solib_create_inferior_hook): Lint.
1726 (sharedlibrary_command): Move dont_repeat to here.
1727 * utils.c (error): Call wrap_here to force buffered output.
1729 Small patches from Peter Schauer:
1731 * coffread.c (start_symtab): Free any existing line_vector before
1733 (read_coff_symtab): Ditto for type_vector.
1735 * source.c (lines_to_list): New variable, replacing function.
1736 (all uses): Use as variable.
1737 (_initialize_source): Add 'set listsize' and 'show listsize'.
1738 * utils.c (lines_to_list): Remove function.
1739 * stack.c (print_frame_info): Use as variable.
1740 * defs.h (lines_to_list): Remove declaration.
1742 Mon Sep 9 13:45:57 1991 John Gilmore (gnu at cygint.cygnus.com)
1744 * breakpoint.c (insert_breakpoints): Restore warning about
1745 the program might be running in another process, but only for
1746 systems with this brain death (#ifdef ONE_PROCESS_WRITETEXT).
1747 * xm-hp300bsd.h, xm-mips.h, xm-vax.h: Define it.
1749 * utils.c (error): if error_pre_print is set, print the string
1751 * main.c (main, print_gnu_advertisement, print_gdb_version):
1752 Reformat legalese so it always prints, but acts as an "I'm here"
1753 message while symbols are being read. If any errors occur,
1754 print a few newlines to set off the message and start it at the
1755 left margin. Remove mention of "help" command, and don't yak
1756 about symbol reading.
1757 (catch_errors): Error string is now printed first in case of
1759 * command.c (undef_cmd_error, lookup_cmd): On undefined command,
1760 suggest the "help" command.
1762 * Makefile.in (VERSION): Set to 4.0.2.
1764 Thu Sep 5 23:49:48 1991 John Gilmore (gnu at cygint.cygnus.com)
1766 * .gdbinit: Remove useless "rr" command. Set complaints
1767 to 1 for people debugging gdb.
1769 * breakpoint.c, remote-vx.c: Reword strings printed by
1770 catch_errors callers.
1772 Wed Sep 4 11:07:50 1991 John Gilmore (gnu at cygint.cygnus.com)
1774 * WHATS.NEW: "history write -> history save". Doc "write on/off".
1775 (Fix from kenc@viewlogic.com.)
1777 Fix some infrastructure to be able to cope with host and target
1778 machines with different sized basic types (ints, ptrs, etc).
1779 (Idea from pierre@la.tce.com (Pierre Willard).)
1781 * values.c (value_from_longest): Rename from value_from_long.
1782 Handle pointer types as well as integers, so that targets with
1783 different pointer sizes from the host can be accomodated.
1784 * breakpoint.c, convex-tdep.c, eval.c, expprint.c, printcmd.c,
1785 valarith.c, valops.c, valprint.c, value.h, values.c: Rename
1786 uses of value_from_long to value_from_longest.
1787 * eval.c, findvar.c, printcmd.c, valarith.c, valops.c: Pass
1788 the correct pointer type to value_from_long{est}.
1790 * doc/gdb.texinfo ($_, $__): Describe types of these variables.
1792 * remote-vx.c: Remove obsolete code for calling functions via
1793 vxworks kludge interface (it referenced value_from_long).
1795 * valops.c (value_string): Find malloc with lookup_misc_func, not
1798 Tue Sep 3 18:37:46 1991 John Gilmore (gnu at cygint.cygnus.com)
1800 Make writing to files work properly. (Fixes to BFD are also needed.)
1802 * core.c (core_open): Open file ourselves, read or r/w, depending on
1803 write_files. Use bfd_fdopenr.
1804 * gdbcore.h (write_files): New variable.
1805 * exec.c (write_files): Define variable, add set&show for it.
1806 (exec_file_command): Use write_files to open for read or r/write.
1808 Make shared library reading happen automatically. These changes
1809 are mostly from Peter Schauer <pes@regent.e-technik.tu-muenchen.de>.
1811 * inferior.h (stop_soon_quietly): Add to exported variables.
1812 * infrun.c (child_create_inferior): call solib hook, if defined.
1813 (child_attach): call solib hook, if defined.
1814 * solib.c: Include inferior.h. Add from_tty to so_list as kludge.
1815 (find_solib): Use lookup_misc_func rather than hand-rolled.
1816 (symbol_add_stub): New stub for catch_errors.
1817 (solib_add): Avoid output if !from_tty. Catch errors rather
1818 than just calling symbol_file_add and bombing.
1819 (solib_create_inferior_hook): Interface with the target process
1820 to let it read and alloc shared libs, then figure out what it did.
1822 * core.c (validate_files): Fix typo, soften warning.
1823 (Fix from Hiroto Kagotani <kagotani@cs.titech.ac.jp>.)
1825 * utils.c (fputs_demangled): Avoid duplicate printing if
1826 demangling is off. (Fix from J.T. Conklin <jtc@cayenne.com>.)
1828 * infrun.c (proceed): Cast -1 to (CORE_ADDR) before comparing.
1829 (Fix from pierre@la.tce.com (Pierre Willard).)
1831 * main.c (catch_errors): Change argument to a char * from an int,
1832 since a char * can point to a struct full of glop, but an int
1833 is not guaranteed to be able to hold a pointer.
1834 * breakpoint.c (breakpoint_cond_eval, bpstat_stop_status,
1835 breakpoint_re_set_one, breakpoint_re_set): Adapt.
1836 * core.c (core_open, solib_add_stub): Adapt.
1837 * remote-vx.c (symbol_stub, add_symbol_stub, callers): Adapt.
1839 Wed Aug 28 18:18:05 1991 John Gilmore (gnu at cygint.cygnus.com)
1841 * Makefile.in: Update VERSION to 4.0.1. Evade GNU Make bug
1842 by adding .NOEXPORT target.
1844 Fri Aug 23 17:14:25 1991 John Gilmore (gnu at cygint.cygnus.com)
1848 * Makefile.in (VERSION): Roll to 4.0.
1849 (gdb.tar.Z): Make refcard.ps as well, for shipment.
1851 Fri Aug 23 14:07:09 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1853 * doc/gdb.texinfo: minor rewordings, crossref to ptype from print,
1856 * doc/Makefile, Makefile.in: generate "gdb-all.texi" rather than
1859 * doc/rdl-apps.texi: renamed from rdl-apps.texinfo
1861 * Makefile.in, doc/Makefile, doc/.Sanitize, doc/gdb.texinfo:
1862 reflect above name change
1864 * WHATS.NEW: correct pointer to refcard.
1866 * doc/gdb.texinfo: update New Features, Installing
1868 * doc/gdbint.texinfo: add short description of configure +template
1870 Fri Aug 23 11:46:08 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1872 * doc/gdb.texinfo: update, fix bugs in "Installing" appendix
1874 Fri Aug 23 01:02:00 1991 John Gilmore (gnu at cygint.cygnus.com)
1876 * Makefile.in: Add config.sub, make doc/rdl-apps.texinfo for
1877 tar file, add dependencies for referenced doc files.
1879 Thu Aug 22 22:17:06 1991 Stu Grossman (grossman at cygint.cygnus.com)
1881 * coffread.c, symfile.c, stack.c: saberized.
1883 Thu Aug 22 16:20:27 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1885 * doc/refcard.tex: permuted Essential Commands sec
1887 * doc/gdb.texinfo: new C++ chapter; revised installation appendix;
1889 set/show symbol-reloading
1890 default set complaints 0
1892 RET-repeat disabled after prompted long displays
1893 processID (attach) interpretation of 2nd GDB cmdline arg
1895 Thu Aug 22 14:05:47 1991 Stu Grossman (grossman at cygint.cygnus.com)
1897 * expread.y, coffread.c, dbxread.c, target.c, mem-break.c,
1898 cplus-dem.c, values.c, valprint.c, symfile.c, remote.c,
1899 breakpoint.c, main.c: lint.
1901 Thu Aug 22 02:02:26 1991 John Gilmore (gnu at cygint.cygnus.com)
1903 Install new configuration scheme for GDB and friends.
1905 * config.sub: Translate ordinary names to three-part names.
1906 * configure: Use three-part names internally.
1907 * configure.in: Translate three-part names to filenames.
1909 * README, WHATS.NEW: Update for gdb-4.0.
1910 * Makefile.in: Roll VERSION to 3.99.
1912 Wed Aug 21 18:21:09 1991 John Gilmore (gnu at cygint.cygnus.com)
1914 * infptrace.c (KERNEL_U_ADDR_BSD): Include a.out.gnu.h.
1915 * i960-tdep.c, m68k-tdep.c, sparc-tdep.c, tm-i960.h,
1916 tm-m68k.h, remote-nindy.c: Change ext_format_XXX structs
1917 to single structures rather than arrays; when passing
1918 their address, use &. This avoids trouble with bdead compilers.
1919 * mcheck.c: Don't include <stdlib.h>; just declare "void abort();"
1920 instead. This avoids portability headaches.
1921 * mips-tdep.c (mips_do_registers_info): Only print FP regs if
1923 * source.c (open_source_file): Avoid ANSI const bdeath by
1924 skipping declaration and then casting result value.
1925 * tm-hp300bsd.h: Clarify comment.
1926 * utils.c (strstr): Result is const char *; ANSI bdeath.
1927 * xm-hp300bsd.h: Define HOST_BYTE_ORDER. Redefine INT_MIN,
1928 since system include file defines it differently from "defs.h",
1929 though the two are equivalent for our purposes.
1930 * tconfig/hp300bsd: Add m68k-tdep.o.
1932 Tue Aug 20 16:01:11 1991 John Gilmore (gnu at cygint.cygnus.com)
1934 * tconfig/sun*4: Remove warnings about system assembler.
1936 Mon Aug 19 13:44:46 1991 John Gilmore (gnu at cygint.cygnus.com)
1938 * mcheck.c: Avoid warning about undeclared abort fn.
1939 * tm-sparc.h (PC_ADJUST): Avoid calling error() from this;
1940 it causes recursive calls to error() when used in cleanups.
1941 To do so requires that we make it a function, so we do.
1942 * sparc-tdep.c (sparc_pc_adjust): New implem of PC_ADJUST.
1943 * utils.c (do_cleanups): Remove the current cleanup from the
1944 chain *before* calling it, in case error() is called from it.
1945 The result won't be pretty, but won't be an infinite loop either.
1947 Mon Aug 19 00:41:04 1991 Michael Tiemann (tiemann at cygint.cygnus.com)
1949 * dbxread.c (read_struct_type): Grok anon structs for C++.
1950 (vb_name, vptr_name): Null terminate these strings.
1952 Fri Aug 16 08:31:03 1991 John Gilmore (gnu at cygint.cygnus.com)
1954 Minor bug fixes from BSD Net2 gdb:
1956 * blockframe.c (get_prev_frame_info): If FRAME_CHAIN_COMBINE
1957 returns 0, there is no previous frame.
1958 * breakpoint.c (commands_command): If !from_tty, don't call
1959 input_from_terminal_p().
1960 * dbxread.c (record_misc_function): Speed up slightly.
1961 (compare_psymbols): Ditto.
1962 * infcmd.c (do_registers_info): Take a second argument to
1963 determine whether to print float registers. "info registers"
1964 does not do so anymore. "info all-registers" does, now.
1965 * mips-tdep.c, pyr-tdep.c (xxx_do_registers_info): Take second
1967 * tm-mips.h, tm-pyr.h (DO_REGISTERS_INFO): Pass second arg.
1968 * inflow.c (initialize_inflow): Set tflags_ours correctly.
1972 * breakpoint.c (bpstat_do_actions): Use a cleanup to restore
1973 executing_breakpoint_commands if we are interrupted by error.
1974 * coffread.c (init_lineno): Avoid problem with zero-sized linetab
1975 versus malloc/free. From: john@labtam.labtam.oz.au (John Carey).
1976 * core.c (solib_add_stub, core_open): Call SOLIB_ADD inside a
1977 catch_errors() so we can setup the frame regardless of whether
1978 the shared libs work.
1979 * ieee-float.c (double_to_ieee_extended): Get exponent from
1980 right place in little-endian systems. From John Carey.
1982 Thu Aug 15 18:43:57 1991 John Gilmore (gnu at cygint.cygnus.com)
1984 * main.c: Remove unused terminating_signals and catch_termination().
1985 (long_options): Terminate with a zero element.
1986 [Bugfix from Atsuo Kawaguchi <atsuo@hark86.harl.hitachi.co.jp>.]
1987 (gdb_readline): Make call-compatible with readline.
1988 (init_signals): Improve comments re vfork vs. signal.
1990 * utils.c (prompt_for_continue): Use new gdb_readline().
1991 If we prompt for continuation, we don't let CR repeat the previous
1992 command, once we get back to a prompt. It's too easy to keep
1993 hitting CR, expecting "--more--" prompts, and have some long
1994 command start repeating on you.
1996 Tue Aug 13 16:17:56 1991 John Gilmore (gnu at cygint.cygnus.com)
1998 * blockframe.c (frameless_look_for_prologue): Speed up by
1999 calling SKIP_PROLOGUE_FRAMELESS_P if it's defined.
2000 * tm-sparc.h (SKIP_PROLOGUE, SKIP_PROLOGUE_FRAMELESS_P):
2001 Define two variants, one faster.
2002 * sparc-tdep.c (sparc_frame_chain): Use target_read_memory
2003 and return zero, rather than giving an error.
2004 (setup_arbitrary_frame): Initialize the PC in the new frame.
2005 (skip_prologue): Add a second arg saying whether we're just
2006 checking for a frameless function or not.
2008 * core.c (core_open, core_close, core_xfer_memory): Move
2009 section table pointers and bfd* into the target_ops.
2010 (core_open): Allow errors in shared lib reading, etc.
2011 (core_files_info): Describe shared library sections.
2013 * exec.c (exec_open, exec_close, exec_xfer_memory, xfer_memory,
2014 exec_files_info, set_section_command): Move section table
2015 pointers and bfd* into the target_ops.
2016 (add_to_section_table): Add BFD to section table.
2018 * target.c (target_xfer_memory, target_info): Pass target to
2019 xfer_memory and target_info functions.
2022 * gdbcore.h: Move struct section_table.
2023 * target.h: New home of struct section_table.
2025 * solib.c (solib_add): New argument is the target_ops whose
2026 section list is to be added to, if any. Reallocate the
2027 sections in that target to add any that come from shared libs.
2028 (throughout) so_sections renamed to sections.
2029 (solib_xfer_memory): Deleted.
2030 * tm-sunos.h (SOLIB_ADD): Add target argument.
2031 (SOLIB_XFER_MEMORY): Delete.
2033 * core.c, exec.c, inftarg.c, remote-eb.c, remote-nindy.c,
2034 remote-vx.c, remote.c, target.c, target.h: Remove add_syms vector
2035 from target_ops. It's the same on all targets. Add two section
2036 pointers to target_ops.
2038 * stack.c (find_relative_frame): Dump ancient algorithm for
2039 "down", just use handy "next" pointers.
2040 (frame_command): Don't error if there is no stack; let user
2043 * inflow.c (new_tty_prefork, new_tty): New prefork routine
2044 modifies static state in the parent process; new_tty itself
2045 runs in the child and modifies the child's file descriptors
2046 to match the saved static state.
2047 * infrun.c (child_create_inferior): Call new_tty_prefork,
2050 * infptrace.c (child_xfer_memory): Add ignored target arg.
2051 * remote-eb.c (eb_xfer_inferior_memory): ''
2052 * remote-nindy.c (nindy_xfer_inferior_memory): ''
2053 * remote-vx.c (vx_xfer_memory): ''
2054 * remote.c (remote_xfer_memory): ''. Rename from
2055 remote_xfer_inferior_memory.
2057 * main.c (main): Only try to attach "corefile" argument if
2058 it starts with a digit.
2060 * symfile.c (symbol_reloading): New "set/show" variable.
2061 (symbol_file_add): Shorten message about symbol reading.
2062 (add_symbol_file_command): Merge with add_syms_addr_command,
2063 since this should work on all targets now.
2064 (stop_whining): Default to zero, to shut up complaints
2065 about bad symbol tables on many systems.
2066 (free_named_symtabs): Just exit unless symbol_reloading.
2068 * xm-sun3os4.h, xm-sun4os4.h: Define BROKEN_LARGE_ALLOCA,
2069 and add comment explaining shared library screw.
2071 * source.c: #if defined => #ifdef.
2073 Thu Aug 8 12:23:19 1991 John Gilmore (gnu at cygint.cygnus.com)
2075 * doc/gdbint.texinfo: Improve doc on porting to new OS's.
2077 Tue Aug 6 17:16:15 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
2079 * doc/rdl-apps.texinfo: provide default readline-appendix finder
2080 (doc/Makefile knows how to make one for local config)
2082 * Makefile.in: use doc/Makefile for doc targets
2084 * doc/Makefile: GDB documentation now has its own Makefile
2085 doc/refcard.tex: renamed from "gdbrc.tex"
2086 doc/.Sanitize: add Makefile; recognize renamed refcard.tex
2087 doc/gdbint.texinfo: add markup in "Cleanups" chapter
2090 Fri Aug 2 00:13:06 1991 John Gilmore (gnu at cygint.cygnus.com)
2092 * values.c (baseclass_addr): When reading target memory, use the
2093 length of the basetype, not the upper type. We've only malloc'd
2094 enough space for the basetype, leading to errors in free().
2096 * expprint.c (print_subexp): Print UNOP_MEMVAL of an OP_LONG that
2097 ends up as a function specially, since we know the actual type of
2098 the pointed-to address. This (somewhat) fixes display of
2099 expressions that include misc_function_vector names. Try `cond 1
2100 !strcmp("a","b")' then `i b'.
2102 * infrun.c: Move DO_DEFERRED_STORES from proceed() to resume().
2103 The child can be proceeded from inside wait_for_inferior in
2104 evaluating breakpoint conditions, and DO_DEFERRED_STORES was
2105 getting skipped in that case.
2107 * expprint.c (print_subexp): Use filtered output, since the
2108 subroutines we call use it, otherwise the output is horribly
2109 mangled, since output of wrappable stuff comes out late.
2111 * Makefile.in: Bump VERSION to 3.98.1
2113 * infrun.c (child_create_process): Use execlp to find the
2114 shell to exec our target program. This requires some fiddling
2115 with `environ' since there is no execlpe().
2117 Thu Aug 1 15:35:17 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
2119 * Makefile.in, doc/gdbrc.tex, doc/rc-* (new files):
2120 Minor rearrangement of refcard permits two new make targets--
2121 gdbrc.dvi DVI output for refcard, using CM fonts
2122 gdbrc.ps PostScript refcard, using PS fonts
2124 Wed Jul 31 16:46:21 1991 John Gilmore (gnu at cygint.cygnus.com)
2128 * TODO, Projects, WHATS.NEW, README: Update for gdb-3.98.
2129 * Makefile.in (gdb-all.texinfo): Avoid touching file if M4 dies.
2131 Wed Jul 31 16:35:58 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
2133 * doc/gdb.texinfo: last changes for release.
2134 Minor typo and formatting fixes; incorporated most fixes remaining from
2135 filed mail commenting on earlier drafts.
2137 Added warnings: pipes don't work in run command;
2138 conditions are converse of assertions;
2139 step over fn without debug info goes to next fn;
2140 vars may have "wrong" values near fn entrance, exit
2142 Added example from Kingston on printing repeated nonadjacent values
2144 Added explicit mention that in Emacs gdb mode C-c and C-z are like
2145 shell mode for signals
2147 Renamed "Stepping and Continuing" to "Continuing and Stepping" so it
2148 doesn't sound so much like its parent "Stopping and Continuing"; also
2149 moved entries on continue to top of section, so they don't get lost.
2151 Improved installation directions in appendix, added manual formatting
2154 Tue Jul 30 17:26:39 1991 John Gilmore (gnu at cygint.cygnus.com)
2156 * configure.in: Remove xm.h and tm.h even if we aren't linking
2157 new ones, so "./configure sun4; ./configure none" does the right
2158 thing. Assume that alldeps.mak and depend are already built in
2159 srcdir, and avoid running "make" (particularly "make depend",
2160 which involves "gcc") from inside configure. Build Makefile
2161 directly rather than building Makefile.conf first.
2162 * configure: Regenerate with above changes.
2163 * Makefile.in: Use $(BISON) to find bison. Roll VERSION
2164 to 3.98. Revise gdb.tar.Z procedure to produce a file
2165 called gdb-$(VERSION).tar.Z but which unpacks into a
2166 directory called "gdb". Move non-source files out of
2167 $(SFILES_SUBDIR). Pretty up alldeps.mak with comments.
2168 (depend): Don't try to do "gcc expread.y".
2169 (expread.o): Update dependencies by hand.
2171 Mon Jul 29 15:21:09 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
2174 Fixed a variety of small typos that prevented info from formatting
2175 cleanly; altered too-long heading for GPL Appendix, as discussed
2176 w/RMS; Changed date on cover to July 91.
2178 Fri Jul 26 13:20:02 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
2181 (1) Applied some fixes due to comments from Larry Breed (easier ones
2182 through chapsec 5.2)
2183 (2) Eliminated use of @footnote---had my doubts about it anyways, and
2184 it's broken in latest texinfo
2185 (3) Introduced *some* use of [] for optional arguments, where
2186 explanation is not simpler by listing cmd w arg and cmd w/out arg
2187 separately. Still not using @deffn.
2188 (4) Dropped in GPL-2. NOTE: one of GPL-2 or texinfo is broken; a
2189 couple of headings are too long. Need patches to texinfo or revision
2192 * Partial update to README (which still needs work for this
2193 release!): (1) use of configure corrected for new script,
2194 (2) "make gdb.dvi" and "make gdb.info" mentioned.
2196 Wed Jul 24 06:44:02 1991 John Gilmore (gnu at cygint.cygnus.com)
2198 * symtab.c (lookup_symbol): Don't complain right off about
2199 no debug symbols; use the misc function vector first.
2200 (list_symbols): Use misc function vector to find symbols
2201 that don't have debug info, and print them.
2202 (find_pc_symtab): Temporarily avoid fatal() when psymtab
2203 PC range doesn't match symtab PC range, as it does on the
2204 MIPS because our symtab reading isn't perfect.
2206 * dbxread.c (dbx_symfile_read): Make warning about
2207 "no debug symbols" slightly nicer.
2209 * source.c (select_source_symtab): If "main" symbol exists,
2210 but decode_line_spec can't find line info, don't just return
2211 a zero; try other source symtabs or give an error.
2213 * mipsread.c (parse_partial_symbols): Sort the psymtabs by
2214 their low addresses first, then rip through fixing high addrs.
2216 * ns32k-opcode.h (sfsr): Bugfix from Rune Nerg}rd,
2217 <runene@ifi.uio.no>.
2218 (NS32K_SVC_IMMED_OPERANDS): Reverse the #ifndef.
2220 Tue Jul 23 18:52:43 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
2222 * Minor, mostly mechanical, cleanup of doc subdir for clean
2223 makeinfo'ing and TeXing; also ensured gdb-all.texinfo (post-m4)
2224 and gdb.info (post- texinfo2 makeinfo) generated for distribution.
2226 Sun Jul 21 03:54:52 1991 John Gilmore (gnu at cygint.cygnus.com)
2228 Mostly MIPS and general symbol-reading fixups.
2230 * doc/gdbint.texinfo: Add documentation on symbol-reading
2233 * mipsread.c: Remove kludges around #include "ecoff.h".
2234 Remove redefinitions of a_magic, etc, no longer used.
2235 (parse_symbol, ): Convert "Internal:" printfs to complain()ts.
2236 Fix global overview comments to match symfile.c protocol.
2237 (mipscoff_new_init): Eliminate cur_hdr if we have one.
2238 (mipscoff_symfile_read): Eliminate unused code. Avoid
2239 sorting all the symtabs, when all we have read here is psymtabs.
2240 The symtabs are sorted as they are created anyway. Tell
2241 condense_misc_bunches whether we're mainline.
2242 (psymtab_to_symtab_1): Pass filename when recursing, to make
2243 stack trace more informative.
2244 (parse_partial_symbols): Assume cur_hdr as argument.
2245 (read_mips_symtab): Don't clobber cur_hdr, so it can be freed.
2246 Pass cur_hdr implicitly to parse_partial_symbols. Avoid checking
2247 the TYPE_NAME of char *, since that's done in symfile.c.
2248 (free_numargs, parse_symbol, add_symbol, add_block,
2249 shrink_linetable): Declare these fns void.
2250 (upgrade_type): Convert tree of if's to switch. Clean up
2251 bogus "off == 0" handling with a complaint. Avoid setting
2252 field bitpos and bitsize of array with lower and upper bounds.
2253 Check specified bitsize of elements against their actual type's
2254 bitsize, and complain if different. Complain about unknown
2256 (parse_fdr): Don't assume sizeof(char *) == sizeof (struct *).
2257 (psymtab_to_symtab_1): Print names of subsidiary files that
2258 are being read in. FIXME, we read far too many files. This code
2259 is not the problem, the problem is in parse_fdr where the psymtabs
2261 (cross_ref): Result should indicate that we used one aux entry
2262 normally, or two if we encountered a "next" entry. This used
2263 to leave the caller pointing at the wrong aux entry.
2264 (add_symbol): If overflowed cur_block, reallocate it larger,
2265 chase all pointers to it, and complain(), rather than clobber memory.
2266 (shrink_block): Use xrealloc rather than xmalloc-and-copy.
2267 (new_field): Only allocate one field initially, not two.
2268 Pull ++ out of macro argument. Simplify.
2269 (_initialize_mipsread): Avoid initialization of importd
2270 global_psymbols and static_psymbols.
2272 * symfile.c (psymtab_to_symtab): Depend on XXX_psymtab_to_symtab
2273 to properly set pst->symtab; avoid searching for it.
2274 (symfile_fns): Improve comments, add a FIXME.
2275 * dbxread.c: Update comments to reflect symfile protocol.
2276 (read_ofile_symtab, end_symtab): Return the symtab.
2277 (psymtab_to_symtab_1): Set pst->symtab.
2279 * coffread.c (coff_symfile_read): tell condense_misc_bunches
2280 whether we're mainline.
2282 * symfile.h (sym_fns): Remove unused sym_discard member.
2283 * coffread.c, mipsread.c, dbxread.c: Remove XXX_symfile_discard.
2285 * mtrace.c (mtrace): Take effect if mallwatch is set, even if
2286 the environment variable is not.
2287 * infcmd.c (finish_command): Use filtered printfs.
2288 * cplus-dem.c: Add struct tags to a few unnamed structs.
2289 * valops.c (value_coerce_array): Improve comments.
2290 * valprint.c (type_print_varspec_suffix): Print array size only
2291 if greater than zero.
2292 * m88k-tdep.c: Shift some lines left by one space, that had
2293 apparently been trashed at some point.
2294 * TODO: More things to do, a few got done.
2296 Thu Jul 18 22:46:05 1991 John Gilmore (gnu at cygint.cygnus.com)
2298 * symtab.h (LOC_EXTERNAL): Eliminate in favor of LOC_STATIC.
2299 (ldsymoff, ldsymlen, globals_offset, statics_offset): Improve
2301 * dbxread.c (read_dbx_symtab): LOC_EXTERNAL -> LOC_STATIC.
2302 * expread.y, findvar.c, symmisc.c: Ditto.
2303 * printcmd.c (address_info): Update printed forms of LOC_
2304 symbols. Elim LOC_EXTERNAL.
2305 (print_frame_args): Keep track of param stack offsets before
2306 re-looking up to find the local register param is kept in.
2308 * mipsread.c: Use <symconst.h> and <sym.h> rather than <syms.h>.
2309 Further integration of mipsread into gdb. Eliminate unused
2310 routines, duplicate declarations. Handle static symbols in
2311 psymtabs as well as external symbols. When reading symtabs,
2312 insert symbols into the correct block (global, static, or a local
2314 (read_mips_symtab, parse_partial_symbols): Don't pass useless
2316 (mipscoff_symfile_read): Don't call select_source_symtab.
2317 (parse_symbol): Use SYMBOL_VALUE_ADDRESS where appropriate,
2318 rather than SYMBOL_VALUE.
2319 (parse_external): Comment clobbering of top_stack.
2320 (parse_partial_symbols): Update comments. Allocate and parse
2321 static symbols as well as external symbols. FIXME, enum values
2322 are not handled in this pass, but should be. Inline new_psymbol.
2323 Use SYMBOL_VALUE_ADDRESS.
2324 (psymtab_to_symtab_1): Read symbols into global static block
2325 by default (until enter some function's local block context).
2326 (sort_blocks): Clean up STATIC_BLOCK as well as GLOBAL_BLOCK.
2327 (destroy_all_symtabs, new_psymbol): Eliminate, unused.
2329 * source.c (select_source_symtab): Select a source symtab
2330 from either the symtabs or, failing that, the psymtabs.
2331 (list_command): Update error message.
2332 (forward_search_command, reverse_search_command): Use getc, not
2333 fgetc, for speed. FIXME, add comment about buffers that die if
2334 overrun by long line.
2336 * values.c (unpack_field_as_long, modify_field): Avoid shifting
2337 by an entire word, which is not portable, if we have a 32-bit
2338 field. (Code in dbxread.c already turns such bitfields, if
2339 aligned, into ordinary ints, but fixing this will help for other
2340 symbol formats and for future changes.)
2341 * core.c (core_open): Handle ANSI const brain death.
2342 * utils.c (vprintf): Fix varargs typo.
2344 Sun Jul 14 00:42:53 1991 John Gilmore (gnu at cygint.cygnus.com)
2346 * findvar.c (find_var_value): Handle &function better.
2347 * TODO: Document work needed on &fn and &array.
2348 * printcmd.c (print_address_symbolic): New arg is the prefix
2349 to print if a name is printed.
2350 (print_address_demangle): Honor "set print address" now.
2351 Use new arg above to improve spacing of output.
2352 * valprint.c (val_print): When printing function pointers,
2353 print symbolic form too.
2354 * breakpoint.c (breakpoint_1): Use new print_address_symbolic.
2356 Mon Jul 8 19:02:46 1991 John Gilmore (gnu at cygint.cygnus.com)
2358 * core.c (memory_error): Reword error msg to mislead less.
2360 * mips-pinsn.c (print_insn_arg 'd'): Print $ with reg name.
2362 * mipsread.c (read_mips_symtab, read_the_mips_symtab,
2363 parse_partial_symbols): Use newer BFD internals (external_filehdr
2364 and external_aouthdr), byte-swap the fields that we care about
2365 before using them, and make the file header data local to
2366 read_the_mips_symtab rather than global.
2368 Sat Jul 6 01:34:15 1991 John Gilmore (gnu at cygint.cygnus.com)
2370 * ns32k-opcode.h (movmw, movmd): Fix opcodes. Bug fix
2371 from Rune Nerg}rd <runene@ifi.uio.no> on 5 Jul 1991.
2373 * main.c (command_line_input): Flush stdout and stderr
2374 before every call to readline. This reportedly fixes a bug
2375 that comes up in Sys V running emacs-gdb and/or xxgdb,
2376 when stdin/out are pipes or sockets.
2378 Thu Jul 4 14:47:06 1991 John Gilmore (gnu at cygint.cygnus.com)
2380 * configure.in, Makefile.in: Avoid rebuilding "depend" as much.
2381 Avoid declaring Makefile dependencies, because GNU Make stupidly
2382 tries to update it if we do.
2384 * coffread.c: Revise for minor changes to bfd internal coff
2387 * configure: If -template= is given a relative path, make it
2388 absolute before recurring in subdirectories.
2390 * configure, configure.in, Makefile.in: Install "configure" script
2391 as replacement for config.gdb.
2392 * config.gdb, Makefile.dist, Makefile.sdir: Remove
2393 * README: Update for configure, mostly. FIXME.
2395 * Add dec3100 as equivalent to littlemips. Indicate in all host &
2396 target config files that they are for the host. When the lines
2397 get copied into the Makefile, this makes it more obvious what's
2400 Mon Jun 24 23:49:07 1991 John Gilmore (gnu at cygint.cygnus.com)
2402 * sparc-opcode.h (trap opcodes): Avoid leading spaces or
2403 tabs, which end up in the disassembler output inadvertently.
2405 Wed May 29 23:01:03 1991 John Gilmore (gnu at cygint.cygnus.com)
2407 Make it compile cleanly in an ANSI GCC2 environment.
2409 * blockframe.c: <stdio.h>
2410 * cplus-dem.c: free takes a void *, ifdef __STDC__
2411 * dbxread.c (read_huge_number): avoid gcc2 bug hoisting calc of
2413 * defs.h (alloca): Avoid doing anything if alloca already def'd.
2414 * stddef.h, stdlib.h: Remove these files.
2415 * symtab.c: Avoid declaring qsort, close.
2416 * symfile.c: Avoid declaring close.
2417 * utils.c (vprintf): Declare "ap" arg as proper va_alist.
2418 * sparc-tdep.c: Avoid including lots of Sun-host-specific files.
2420 Assorted other changes.
2421 * dbxread.c: include "libaout.h", not "liba.out.h".
2422 * printcmd.c (print_frame_args): Set recurse properly for
2423 indentation of struct and array parameters.
2424 * valops.c (value_cast): Allow cast to void.
2425 * infrun.c (resume): If NO_SINGLE_STEP, call machine dependent
2426 single_step() in a target-independent fashion.
2427 * sparc-tdep.c (single_step): Don't call ptrace ourselves, just
2428 set up to be ready to continue. This makes us target independent.
2429 * infptrace.c (child_resume): Remove call to single_step; now
2430 can single step a SPARC target of any kind.
2432 Wed May 22 18:18:24 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
2434 * Makefile.dist, doc/gdb.texinfo, doc/*-m4.texinfo: split up GDB
2435 docn into separate sections---basically chapters, plus two loose
2436 pieces that can be configured to go in different places. This
2437 allows GNU m4 to preprocess the manual without coredumping.
2439 * Makefile.dist: tell TeX where to find texinfo.
2441 Mon May 20 12:15:04 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
2443 * Makefile.dist, doc/gdb.texinfo: respectively create, and use,
2444 the new target "rdl-apps.texinfo" which captures the Makefile
2445 variable that records where to find the Readline libraries.
2447 Sun May 19 05:36:59 1991 John Gilmore (gnu at cygint.cygnus.com)
2449 * tahoe-pinsn.c: #include "tahoe-opcode.h", not "opcode.h".
2450 * tm-tahoe.h (FIX_CALL_DUMMY): Ignore more parameters.
2451 * defs.h (const, volatile): Only define if not already defined.
2452 * Makefile.dist (gdb.tar.Z): Create doc subdir w/out CVS/RCS crud.
2454 * README: Update for release 3.95.
2455 * config.gdb: Don't create readline dir in subdir builds.
2456 * main.c: Include with "..." form for non-system include files,
2457 so "gcc -MM" for "make depend" works.
2458 Include readline files with "...h" rather than <readline/...h>.
2459 * mipsread.c: Include "ecoff.h" rather than "intel-coff.h".
2461 * coffread.c: Undo minor damage done by Rich Pixley. Use
2462 different internal and external representations of COFF
2463 data structures. Use new BFD routines for swapping them in and
2465 * symfile.c (free_named_symtabs): Avoid freeing file names that
2466 are null or empty. Old i960 tools seem to produce files that
2467 claim to have empty names, causing each successive file read
2468 to blow away the previous one.
2469 * sparc-xdep.c (deferred_stores): Repair minor damage by Rich.
2470 Move deferred_stores to top of file, but don't separate its
2471 #define's from its variable. Add commentary.
2472 * Makefile.dist: Fix Rich damage; undo "configure" changes in
2473 favor of keeping the (working) config.gdb. Move readline
2476 Fri May 17 12:49:56 1991 Per Bothner (via gnu at cygint.cygnus.com)
2478 * dbxread.c (read_struct_type): Try to handle g++ version 1 MI
2480 * infptrace.c (fetch_registers): no result, since now void.
2481 * tconfig/news: target depends on m68k-tdep too.
2483 Fri May 17 14:40:14 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
2485 * Makefile.dist: added readline/inc-*.texinfo to dependencies for
2488 * readline/inc-history.texinfo, readline/inc-readline.texinfo:
2489 applied various small fixes due to or inspired by RMS comments
2491 * doc/gdb.texinfo: finished using all RMS comments, save those for
2492 appendices on readline and cmd history (which are in other source
2495 Thu May 16 18:06:05 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
2497 * doc/gdb.texinfo: (1) Updated w/ref to RMS comments through
2498 chapter 9; (2) documented 'break' command's menu mode for
2499 overloaded names, in response to hgs problem report C++ p-31
2501 Wed May 15 11:02:48 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
2503 * doc/gdb.texinfo: (1) better introductory example; (2) more
2504 consistent use of @code, @samp, @file, @kbd throughout; small
2505 cleanups to first three nodes; (3) new "Contributors" node;
2506 (4) Appendix, Renamed Commands; (5) divert specialized startup
2507 instructions to "Targets" chapter for generic manuals, while
2508 leaving them up front for manuals specific to specialized
2509 environments; (6) apply fixes from RMS comments through chapter 4.
2511 * pretex.m4: modify explanatory text slightly (and redefine
2512 "regexp") to keep GNU m4 from complaining. (It still crashes
2513 later, but one step at a time...)
2515 Wed May 15 10:32:12 1991 John Gilmore (gnu at cygint.cygnus.com)
2517 * readline/readline.c (update_line): Avoid dereferencing a pointer
2518 before comparing it to its bounds. Saber caught this.
2519 (init_terminal_io): Don't set BC from the "pc=" termcap variable,
2520 and only set PC if tgetstr returned non-null. Saber caught this.
2522 Tue May 14 16:29:53 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)
2524 * Makefile.dist: put gdb.dvi stuff (updated to use M4 preprocessor
2525 stuff for config manual) here where it counts; updated
2526 to use new subdir structure (gdb/doc/).
2528 * Makefile: generated from above via
2532 * gdbint.texinfo: added instructions on generating gdb.info* files
2533 locally for release. These are ordinary info
2534 files, formatted from gdb.texinfo (via gdb-all.texinfo, see
2535 Makefile)---but due to use of texinfo 2, can't count on makeinfo
2536 to generate these, so we distribute them already formatted.
2538 * gdb.texinfo: included full Info node and menu crud (as generated
2539 by C-u M-x texinfo-master-menu using the texinfo-2 elisp code).
2541 * Makefile: updated "gdb.dvi" target to use M4 preprocessor;
2542 put in comments-for-future gdb.info target (one day makeinfo will
2545 Tue May 14 13:51:36 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)
2547 * gdb.texinfo: Updated to include new or old undocumented
2548 commands, at least the following (perhaps some others I forgot to
2549 record): info f, info float, info path, info program, info s, info
2550 set, info source, info terminal, info types, info user, set/show
2552 Also covered all recent GDB command renames for v4.
2554 Mon May 13 14:57:46 1991 John Gilmore (gnu at cygint.cygnus.com)
2556 * mipsread.c: Rather than keeping count of how many symtabs
2557 and psymtabs we have, for sorting purposes, count them when
2558 we need to sort. This fixes bug in rereading of symbol tables.
2560 Fri May 10 15:43:33 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)
2562 * infcmd.c: renamed "info path" to "show paths"

2576 * coffread.c, exec.c, infptrace.c, inftarg.c, remote.c, solib.c,
2577 symtab.h, target.c, target.h: Lint.
2578 * core.c: setup and select frame after reading shared libs,
2579 else reading shared libs will clobber them. Lint.
2580 * utils.c (error): Force out any buffered wrap text.
2582 Fri May 3 22:01:56 1991 John Gilmore (gnu at cygint.cygnus.com)
2584 * remote.c: Remove decls of memory_insert_breakpoint
2585 and memory_remove_breakpoint, no longer used. (Suggestion of
2588 * Makefile.dist: use ${subdir} in paths of BFD and LIBIBERTY,
2589 to make it easier to interface to "configure"'d libraries.
2591 Fri May 3 13:10:01 PDT 1991 Roland Pesch (pesch at fowanton.cygnus.com)
2593 * valprint.c: introduce "set p", "set pr", "show p" and "show pr" as
2594 aliases for set/show print.

2888 (2, 3) Look in the STATIC_BLOCK for all the symtabs and psymtabs
2891 * main.c (cd_command): Call dont_repeat.

3106 core.c, exec.c, remote-eb.c, remote-nindy.c, remote-vx.c,
3107 remote-vx.68.c, inftarg.c, remote.c: Add doc field to target struct.

3137 command is add-symbols.
3138 * target.c (dummy_target): Permit add_syms_addr_command.
3140 Sat Apr 13 14:46:07 1991 John Gilmore (gnu at cygint.cygnus.com)
3142 Permit symbols to be superseded when new symbol files have
3143 been read in, particularly for VxWorks.
3145 * dbxread.c (read_dbx_symtab): Allow N_SOL to cleanly take us back
3146 to the main file, as well as to include files. Also, put global
3147 functions into the global psymtab, to make "i fun" work.
3148 (end_psymtab): Free named symtabs and psymtabs for a file, once a
3149 new psymtab for it has been read.
3150 * coffread.c (end_psymtab): Free named symtabs and psymtabs for
3151 a file, once a new symtab has been read for it.
3152 * mipsread.c: FIXME. We need to do the same for MIPS, but it
3153 looks harder to determine the top-level block before it's been
3154 queued to the psymtab list.
3156 * symfile.c (symbol_file_add): Use filtered printing and wrap it.
3157 If we have wiped out any old symbol tables, clean up at end of
3159 (symbol_file_command): Don't reference symfile_fns if it's zero.
3161 * symtab.h (GLOBAL_BLOCK, STATIC_BLOCK, FIRST_LOCAL_BLOCK): New
3162 defines for the blocks of a blockvector that contain global and
3163 file-static symbols and the first of the smaller scope contours.
3164 * symtab.c (lookup_symbol, find_pc_symtab, find_pc_line,
3165 decode_line_1, make_symbol_completion_list): Use the above.
3166 * coffread.c (end_symtab, patch_opaque_types): Ditto.
3167 * dbxread.c (end_symtab): Ditto.
3168 * expread.y (block): Ditto.
3169 * mipsread.c (throughout): Ditto.
3170 * symmisc.c (free_named_symtabs): Ditto.
3172 * symtab.c (list_symbols): Process the first symbol of the
3173 static psymbols list.
3174 (types_info): Restore this function from its untimely #if 0.
3175 It's not perfect, but it is better than nothing.
3176 (_initialize_symtab): Restore "info types".
3178 Thu Apr 11 05:23:19 1991 John Gilmore (gnu at cygint.cygnus.com)
3180 * m68k-stub.c: Remote stub for 680x0's, created from
3181 rem-m68k.shar (which is removed).
3182 * nindy-share/{Makefile,Onindy.c,blout.h,env.h,nindy.c,ttyflush.c}:
3183 Remove RCS log stuff now that we use CVS and it blows our diffs.
3185 Wed Apr 10 14:18:06 1991 John Gilmore (gnu at cygint.cygnus.com)
3187 * symmisc.c (free_named_symtab): Make it work, in its current
3188 kludgy fashion. Change result to indicate if we blew away bkpts.
3189 * dbxread.c (end_symtab): Accumulate result from
3190 free_named_symtab and print warning if we blew user's state.
3191 * symfile.h: free_named_symtab now returns an int.
3193 Mon Apr 8 23:57:43 1991 John Gilmore (gnu at cygint.cygnus.com)
3195 * dbxread.c (dbx_symfile_read): Initialize psymbol list if this
3196 is the first symbol read, even if not mainline.
3197 (dbx_psymtab_to_symtab): symfile might be zero, cope.
3198 * exec.c (exec_ops): Add_syms_addr is valid in our tvec.
3199 (set_section_command): New command ("section xxx yyy" -- should
3200 be renamed to "set section xxx yyy" FIXME) which sets the
3201 base address of a section of the exec file, overriding the
3202 virtual address that BFD reports.
3204 Fri Apr 5 17:14:39 1991 John Gilmore (gnu at cygint.cygnus.com)
3206 * exec.c: Add add_syms_addr_command to exec_ops, so you can
3207 load symbols at any address while examining an exec file.
3209 Thu Apr 4 10:09:35 1991 John Gilmore (gnu at cygint.cygnus.com)
3211 * tm-i386v.h (FLOAT_INFO): Don't define it, since the code
3212 for printing the float info is host-dependent, not
3213 target-dependent. FIXME.
3214 * i386-pinsn.c: Move #includes to top, remove useless ones.
3215 * i386-tdep.c: Don't bother including <.../reg.h> since we
3216 don't use it (and it doesn't exist on host systems).
3218 * ieee-float.c (ieee_extended_to_double): Convert NaN to Inf.
3219 Convert negative numbers properly.
3220 (ieee_test): Make numbers really random; fix format arg.
3222 * infcmd.c (attach_command, detach_command): Don't repeat on CR.
3223 * core.c (core_detach): Unpush core_ops, which might not be on
3224 top. We used to just pop the top, which broke things. Don't
3225 need dont_repeat() any more.
3226 (core_file_command): Psst! Don't repeat it.
3227 * remote-nindy.c (nindy_detach): Don't need dont_repeat() now.
3228 * expprint.c (print_subexp): Avoid switch fallthru on
3229 BINOP_ASSIGN_MODIFY, so we can print += and such.
3230 * frame.h: Fix typo.
3231 * inflow.c (kill_command): After killing inferior, print our
3232 current frame in the core file, if we have one.
3233 (generic_mourn_inferior): When inferior dies, either select
3234 the current frame (in the new target, e.g. core file), or
3235 set both the current and selected frames to NULL.
3237 Changes from Peter Schauer.
3239 * infptrace.c: Avoid <sys/ptrace.h> on USG.
3241 * Make all file names fit in 14 characters (sigh and damn!):
3242 mv hp300hpux-xdep.c hp300ux-xdep.c
3243 mv symmetry-xdep.c symm-xdep.c
3244 mv symmetry-tdep.c symm-tdep.c
3245 mv convex-opcode.h convx-opcode.h
3246 mv tm-vxworks960.h tm-vx960.h
3247 mv tm-vxworks68.h tm-vx68.h
3248 mv Makefile.srcdir Makefile.sdir
3249 mv gdb-int.texinfo gdbint.texinfo
3250 mv remote-sa.m68k.shar rem-m68k.shar
3251 mv remote-multi.shar rem-multi.shar
3252 * Makefile.dist, README, config.gdb, convex-pinsn.c,
3253 tconfig/symmetry, tconfig/vxworks960, tconfig/vxworks68,
3254 xconfig/hp300hpux, xconfig/symmetry: Change names to shorter
3257 * command.c (user_info_1, user_info): New command for listing
3258 the user-defined commands.
3260 Wed Apr 3 15:00:26 1991 John Gilmore (gnu at cygint.cygnus.com)
3262 * dbxread.c (really_free_pendings): Clear file_symbols
3263 and global_symbols after freeing them; otherwise, running
3264 this function twice (if it appears twice on the cleanup
3265 chain), we try to free things twice.
3267 * dbxread.c (read_dbx_symtab): Calculate end_of_text_addr
3268 based on text_addr (the address of text in core), not on addr (the
3269 offset between text in the .o file and in core). This change
3270 is from Peter Schauer.
3272 * main.c: Define ALL_CLEANUPS as a cast of zero.
3273 (return_to_top_level): Use it.
3274 (main): Do all cleanups after each command run as part
3275 of the gdb startup sequence. Also do all cleanups before
3276 entering the command loop, and every time we exit the command
3277 loop and reenter. Before, the cleanups from the startup sequence
3278 were being left undone until the first error!
3279 (command_loop): Rename do_nothing cleanup to command_loop_marker
3280 so we can see it easily when examining the cleanup chain.
3281 (init_signals): Add another do_nothing for signal handling.
3282 (quit_command): Only try to kill target if it has execution.
3283 Problems in the target stack got us into a state where
3284 inferior_pid was nonzero but none of the targets had execution.
3285 In this state you couldn't exit gdb.
3287 * dbxread.c: Two changes from Peter Schauer.
3288 (echo_command): Fflush output after an echo command.
3289 (show_history): Pass all args to cmd_show_list.
3291 * utils.c (init_malloc): Call mtrace to turn on tracing
3292 if the environment variable MALLOC_TRACE is set to a file name.
3293 * mtrace.c: Add source file which provides a log of every malloc,
3294 free, and realloc to a trace file.
3295 * mtrace.awk: Add source file which analyzes the trace file.
3296 * Makefile.dist (GNU_MALLOC, MALLOCSRC): Add mtrace.{c,o,awk}.
3297 (VERSION): Roll to 3.94.3.
3299 * breakpoint.c (breakpoint_1): Add a space to "i watch" output.
3300 (check_duplicates): Don't bother with watchpoints.
3301 (set_raw_breakpoint): Comment about danger of this routine.
3302 (watch_command): Parse and eval all args before calling
3305 * solib.c (find_solib): Avoid error in referencing memory to
3306 see if any more shared libraries have been added. This is
3307 particularly useful if the target has terminated. Bug reported
3310 Changes from Peter Schauer <pesrem@regent.e-technik.tu-muenchen.de>
3311 in bringing up 3.94.2 on the Sun-3.
3313 * Makefile.dist: Include CFLAGS in rule for cplus-dem.o.
3314 * breakpoint.c (enable_breakpoint): Check for valid watchpoint
3315 expression (in scope) before reenabling watchpoint.
3316 * signame.c (init_sigs): Add missing declaration of i, fix
3317 sys_siglist declaration.
3318 * source.c (list_command): Fixed range computation to use
3320 * stack.c (backtrace_command): Do not allow command if target has
3321 no stack, print informative error message.
3322 * target.c (target_command): Do not write into command line
3323 because this fails if the target command is used in a user defined
3324 command. [This change was enhanced by gnu to support any-
3325 unique-prefix matching on target names.]
3326 * valops.c (value_struct_elt): Avoid infinite loop on an
3327 erroneous attempt to print the member of function (try p main.p).
3329 Mon Apr 1 17:05:45 1991 John Gilmore (gnu at cygint.cygnus.com)
3331 * expread.y (name_no_typename): Avoid reduce/reduce errors
3332 caused by ambiguity in handling NAME_OR_INT and NAME_OR_UINT.
3333 Since the GDB parser really doesn't use name_no_typename in a
3334 name-only context, the parser can't tell the diff between
3335 names and numbers here. Avoid allowing a name_no_typename
3336 to be a NAME_OR_*INT to resolve the conflict.
3338 Sun Mar 31 20:12:07 1991 John Gilmore (gnu at cygint.cygnus.com)
3340 Bugfixes from Mark Fox (markf@wrs.com) (test=testField.c):
3342 * valprint.c (val_print_fields): bitfield printing didn't handle
3343 byte order. Indirect through a few more fns to cope.
3345 * values.c (modify_field): also cope with byte order.
3347 Sat Mar 23 10:02:21 1991 John Gilmore (gnu at cygint.cygnus.com)
3349 Cleanup for release 3.94.2:
3351 * Makefile.dist: Pull REMOTE_OBS. Fix saber includes for BFD
3352 include files. Roll version to 3.94.2.
3354 * coffread.c (init_stringtab): Read length into unsigned char
3355 array before swapping; don't assume 32-bit longs.
3357 * target.c (target_info): Don't bother with get_sym_file, just use
3358 the symfile global variable.
3359 * symtab.h, symfile.c (get_sym_file): Delete it.
3361 * dbxread.c (dbx_symfile_init): Don't depend on long == 4 bytes.
3362 (define_symbol): Set symbol line number to 0 if not gcc-compiled.
3363 (read_type): Replace one more error() with complain().
3365 * mipsread.c (parse_partial_symbols): Replace printf with complain.
3367 * i960-tdep.c: Fix copyright attribution.
3369 * config.gdb: Quote all backquotes in doublequotes. You can
3370 quote me on that. BSD 4.4 shell found this one.
3372 * infptrace.c (throughout): The third argument to ptrace is an
3375 * infrun.c (wait_for_inferior): When program has terminated, we
3376 have to call target_terminal_ours before we pop that target off
3377 the stack (e.g. before a call to target_kill or
3378 target_mourn_inferior). This fixes problem where a program
3379 terminates, then GDB stops for (tty output) and you have to type
3380 "fg" to the shell to resume it. FIXME: This code for what to
3381 do after termination really should be in normal_stop instead.
3383 * gdbcore.h (read_memory_check): Change declaration; it changed
3386 * terminal.h: Include <sgtty.h> before <sys/ioctl.h>, since in BSD
3387 4.4 prereleases, this avoids a bug in their sgtty compatability
3389 * remote.c: Use terminal.h rather than hand-rolling the same.
3391 * signame.c, signame.h (psignal): Arg is unsigned, not int.
3392 * utils.c (strsave, strstr): Fix arg types.
3393 * valprint.c (val_print): lint
3395 MIPS symbol table support from Per Bothner:
3397 * symfile.c (symtab_fns): Remove initializer table that needs to
3398 be hacked for each new symbol file format supported.
3399 (add_symtab_fns): New function, chains symbol table
3400 handlers into the global list.
3401 (symfile_init): Search this list.
3402 * symfile.h: Add next pointer, declare add_symtab_fns.
3403 * coffread.c (_initialize_coffread): Call add_symtab_fns.
3404 * dbxread.c (_initialize_dbxread): Call add_symtab_fns.
3406 * mipsread.c (psymtab_to_symtab_1): return void instead of (struct
3407 symbol *). Thus, we no longer need the hack to trash
3408 pst->filename. Good, since that hack confused code in symfile.c!
3410 (reorder_symtabs, destroy_all_symtabs): Removed static
3411 all_symtabs, which was used to qsort symtabs in reorder_symtabs.
3412 Instead, the latter now uses a temporary array (stack-allocated
3413 from an obstack, and then freed).
3415 (parse_symbol): Added a hack to fix up BLOCK_{START,END} if they
3416 haven't been set in the outermost stBlock of a procedure. This was
3417 a problem with f77 binaries on Ultrix 4.?.
3419 (new_symtab, new_symbol, new_type): Continue changing code to use
3420 obstacks more and otherwise conform to dbxread internal style.
3421 Made the free_code of symtabs be free_linetable (as in dbxread)
3422 instead of free_contents. This implies memory leaks when reading
3423 a new symbol table, until the conversion is finished. Did change
3424 (struct symbol) and (struct type) to be allocated on the
3425 symbol_obstack. Blocks and blockvectors are among the things
3428 * mipsread.c (parse_partial_symbols, parse_fdr): It hasn't been
3429 tested much, but it solved one problem (reported by Meissner), and
3430 cleans up some other things. The problem happened when an
3431 included file contains actual code (functions) and not just
3432 definitions. The mips coff is a little inconvenient there, since
3433 it may cause a procedure to be mapped to the wrong psymtab.
3435 * mips-tdep.c (heuristic_proc_desc): Minor cleanup.
3436 * mips-xdep.c (fetch_core_registers): Minor cleanup. FIXME,
3437 this will need work for the new core paradigm.
3439 Opcode patches from the net:
3441 * mips-opcode.h: fix incorrect disassembly of the mfc1, cfc1, and
3442 ctc1 instructions. Also, the cvt.d.w and cvt.s.w instructions were
3443 missing altogether - they are added here. From Bruce Bauman.
3444 * mips-opcode.h: The low mask for C0 instructions was too small.
3445 From Garrett Lau. I modified the fix to check the entire 32-bit
3448 * ns32k-opcode.h: Fix opcodes for deiw and deid. From Bruce
3451 Thu Mar 21 12:56:46 1991 John Gilmore (gnu at cygint.cygnus.com)
3453 Roll in changes from Per Bothner (Tue, 25 Sep 90 11:11:04):
3455 * dbxread.c (read_type): Pointer subtraction (value_sub in
3456 valarith.c) sometimes failed because the types of the
3457 pointers being subtracted were not identical.
3458 These differed because dbxread.c was allocating pointer types
3459 using dbx_alloc_type+smash_to_pointer_type instead of
3460 lookup_pointer_type. I failed to find a justification for the
3461 former, so I changed it to use the latter. Similarly, I
3462 replaced smash_to_function_type by lookup_function_type,
3463 and smash_to_reference_type by lookup_reference_type.
3465 * mipsread.c (parse_symbol, upgrade_type, parse_procedure,
3466 _initialize_mipsread): corresponding changes.
3468 * symtab.c (smash_to_{pointer,reference,function}_type): eliminate.
3470 * source.c (mod_path): Do tilde_expand on each component of the path,
3471 rather than on the (list of) paths as a whole.
3472 (print_source_lines): Set first_line_listed in addition to
3473 current_source_symtab and current_source_line. If the source was
3474 not findable, after a "dir" command to fix the problem,
3475 a "list" would get the wrong lines.
3477 While I was there... (gnu):
3479 * dbxread.c (read_type): Change error to complaint.
3481 Thu Mar 21 12:56:46 1991 John Gilmore (gnu at cygint.cygnus.com)
3483 First attempt at detailed understanding of symbol table memory alloc.
3485 * dbxread.c (dbx_symfile_read): Free our string table if we
3486 aren't the mainline. Free the "info" struct since we're done with
3488 (init_psymbol_list): Free any previously allocated psymbol lists.
3489 (): FIXME: Should realloc-down the psymbol lists when done reading
3490 the main symbol file?
3492 * symmisc.c (free_symtab): Free fullname field too.
3494 * xm-hp300hpux.h (USG): #undef then #define so Makefile can -D.
3495 (REGISTER_ADDR): Make result type unsigned int.
3497 * xconfig/{i386*,hp300hpux,altosgas,altos}: All config files that
3498 define REGEX must also define REGEX1 (its dependency).
3500 Tue Mar 19 21:28:57 1991 John Gilmore (gnu at cygint.cygnus.com)
3502 * tconfig/i960: No longer works, points you at vxworks960 or
3505 * xgdb.c, XGDB-README: Remove file. Users can get the much
3507 * Makefile.dist: Remove all trace of xgdb.
3509 * breakpoint.c (breakpoint_1): Pass demangle arg to
3510 print_address_symbolic.
3511 (clear_breakpoints): Remove unused function.
3512 (breakpoint_re_set_one): Guts of breakpoint_re_set.
3513 (breakpoint_re_set): Use catch_errors to do them all anyway.
3515 * gdb-int.texinfo (Host versus Target): Add section on what is
3516 a "host" feature versus what is a "target" feature.
3518 * infcmd.c (path_command, path_info): Handle the PATH variable
3519 (object search path) as conveniently as the source search path.
3520 * environ.c (set_in_environ): Set some vars in GDB's environment,
3521 in addition to the child's. PATH, G960BASE, G960BIN for starters.
3522 * source.c (mod_path): New function, from guts of
3523 directory_command, modifies a path. Used by path_command.
3524 (directory_command): Call it.
3525 * defs.h (strsave): Declare.
3527 * utils.c (sevenbit_strings): Add new printing option.
3528 (printchar): Use it.
3529 (strsave): Provide this handy helper routine.
3530 (set_width_command): Rename set_screen_width_command.
3531 (_initialize_utils): "set screen-width" => "set width";
3532 "set screen-height" => "set height"; add sevenbit-strings.
3534 * infcmd.c (do_registers_info): Print floating point registers
3535 in raw hex as well as float format, regardless of whether it is
3536 a "virtual" convertible register.
3537 * tm-sparc.h (PRINT_REGISTER_HOOK): Print every pair of float
3538 regs as a double, just in case it's being used that way.
3539 * values.c (unpack_long): Comment on array/function coercion.
3540 (unpack_double): Argument is in target byte order now. For
3541 integer arguments, just call unpack_long and float the result.
3542 * m68k-tdep.c: include defs.h for "const" handling.
3543 * remote-nindy.c: Use ieee-float stuff.
3544 (nindy_fetch_registers): Unpack double regs to host double, then
3546 (nindy_store_registers): Pack extendeds to host double, flip
3547 around by misusing unpack_double, send as target double.
3549 * tm-vxworks68.h (FRAME_CHAIN): Handle current frame pointer of
3550 zero, as when stopped at the first instruction of a process.
3552 * blockframe.c: Fix filename in comment (param.h => tm.h).
3553 * sparc-tdep.c (skip_prologue): More explicit nudging comments.
3554 * tm-68k.h: Fix typos.
3556 Fri Mar 15 01:09:34 1991 John Gilmore (gnu at cygint.cygnus.com)
3558 Changes from a bringup on the DEC Vax under Ultrix 4.0.
3560 * coredep.c (fetch_core_registers): Pass end-address of register
3561 section to register_addr as expected. Don't call supply_register
3562 if we'd just pass it garbage.
3564 * dbxread.c (read_dbx_symtab): Skip N_NSYMS on Ultrix.
3566 * exec.c (xfer_memory): Use boolean xfer_fn result, not int.
3568 * target.c (push_target, target_info): Cast enums to int for < or
3571 * stack.c (print_frame_info): Identify source file & line
3572 even if we can't print it.
3574 * xm-vax.h (MISSING_VPRINTF): No longer missing in Ultrix V4.0.
3576 Sat Mar 9 10:08:20 1991 John Gilmore (gnu at cygint.cygnus.com)
3578 Clean up IEEE floating point support.
3580 * ieee-float.h: New file.
3581 * ieee-float.c: Write real routines to convert between host
3582 doubles and various target IEEE extendeds.
3583 * m68k-xdep.c: Eliminate assembler code for extended floats.
3584 * xconfig/{3b1,altos,altosgas,hp300bsd,isi,news,news1000,sun2os3,
3585 sun2os4,sun3,sun3os3,sun3os4}: Eliminate use of m68k-xdep.o.
3586 * tm-i960.h, tm-68k.h (REGISTER_CONVERT_TO_VIRTUAL,
3587 REGISTER_CONVERT_TO_RAW): Use ieee_extended_to_double and
3588 double_to_ieee_extended.
3589 * i960-tdep.c: Define ext_format_i960.
3590 * m68k-tdep.c: Define ext_format_68881.
3591 * sparc-tdep.c: Define ext_format_sparc, though unused.
3592 * Makefile.dist (HFILES): Add ieee-float.h.
3593 * inftarg.c: #include "ieee-float.h" for the REGISTER_CONVERT
3596 Obsolete the "coffstrip" program in favor of using BFD's strip.
3598 * nindy-share/coffstrip.c: Remove file.
3599 * nindy-share/nindy.c (coffstrip): Routine to run bfd_strip.
3600 * Makefile.dist: Remove references to nindy-share/coffstrip.c.
3601 * tconfig/nindy960: Remove reference to coffstrip.o.
3603 * Makefile.dist: Roll version number to 3.94.1 (not yet final).
3605 Wed Mar 6 09:56:45 1991 John Gilmore (gnu at cygint.cygnus.com)
3607 * symfile.h: Add symfile_bfd, common between dbxread and coffread.
3608 * dbxread.c: Remove static symfile_bfd.
3609 * infcmd.c (do_registers_info): Add PRINT_REGISTER_HOOK, though
3611 * inftarg.c (child_detach): Pop the child_ops vector if the
3612 detach is successful.
3613 * remote-nindy.c (nindy_create_inferior): Don't push a new
3614 nindy_ops since nindy uses the same one for execution and memory
3616 * core.c (core_ops): Use child_attach and child_create_inferior
3617 rather than default attach and create_inferior functions.
3619 Handle floating point registers in core files.
3621 * sparc-xdep.c (fetch_core_registers): Rewrite for float support.
3622 * sun3-xdep.c (fetch_core_registers): Rewrite for float support.
3623 This version untested since BFD doesn't yet support sun3 core
3625 * hp300hpux-xdep.c: Rewrite fetch_core_registers to new calling
3626 conventions. Fix comments and style. This version has not
3627 been compiled yet, since we have no HP inhouse.
3628 * core.c (get_core_registers): Look for two sections, ".reg"
3629 and ".reg2", and pass both to fetch_core_registers sequentially.
3631 Revise directory path yet again.
3633 * source.c (forget_cached_source_info): Not static any more.
3634 (init_source_path): New default source path is "$cdir:$cwd".
3635 (dir_command): Handle variable arguments ($cdir, $cwd).
3636 (source_info): Print "Compilation directory" rather than
3637 "Originally compiled in" to remind people of $cdir.
3638 (openp): If the path contains $cwd, use current directory.
3639 (open_source_file): If compilation directory is known, replace
3640 first $cdir in path with the compilation directory.
3641 (print_source_lines): Even if we can't print the lines, set the
3642 current symtab and line for future commands like "info source" or
3643 "breakpoint". Also, error message now contains the file name,
3644 line number, and file access error message.
3645 (_initialize_source): Fix help text to describe changes.
3646 * main.c (cd_command): Forget cached source info when we chdir.
3647 * utils.c (strstr): Add simple implementation.
3649 Tue Mar 5 01:41:40 1991 John Gilmore (gnu at fowanton.cygnus.com)
3651 * coffread.c (read_one_sym, init_linetable, init_stringtab):
3652 Byte-swap COFF symbol tables if necessary when reading them in.
3653 Use complain() to replace error message in one spot. Needs
3654 corresponding change in bfd/coff-code.h to make some symbol
3655 swapping routines non-static.
3657 Mon Mar 4 00:53:40 1991 John Gilmore (gnu at cygint.cygnus.com)
3659 Merge changes from Eirik Fuller, for UTek.
3661 * defs.h (errno): Add declaration.
3662 * altos-xdep.c, arm-xdep.c, convex-xdep.c, gould-xdep.c,
3663 hp300hpux-xdep.c, infrun.c, inflow.c, infptrace.c, i386-tdep.c,
3664 i386-xdep.c, pyr-xdep.c, mips-xdep.c, remote-eb.c, remote-nindy.c,
3665 remote-vx.c, source.c, standalone.c, stuff.c, sun386-xdep.c,
3666 symmetry-tdep.c, symmetry-xdep.c, umax-xdep.c, utils.c: Eliminate
3667 declarations of errno.
3669 * remote-eb.c: Define B19200 and B38400 as EXTA and EXTB.
3671 * remote-vx.c: Include <sys/time.h> for UTek; Sun gets it via
3672 <rpc/rpc.h> and <rpc/types.h>.
3674 Sat Mar 2 15:47:55 1991 John Gilmore (gnu at cygint.cygnus.com)
3676 * i960-tdep.c (examine_prologue): Add new argument limit,
3677 which stops the scan at the end of the prologue, or at the PC.
3678 This fixes a problem where it walks down into the code for the
3679 user's statements if that code looks like function prologues.
3680 Mark Fox and I have been bouncing this code back and forth, making
3681 small changes to it. Callers changed to match.
3683 Tue Feb 26 01:47:07 1991 Cygnus John Gilmore (cygnus at yuba)
3685 Cleanup for gdb-3.94 release final:
3687 * Makefile.dist: Remove remote-vx.c, remote-nindy.c, and all
3688 the .c files from vx-share and nindy-share, from the various
3689 macros, since they are not found via ALLDEPFILES.
3690 (SFILES): Add tm-i960.h.
3691 (alldeps.mak rule): Break out ALLDEPFILES_MAINDIR and
3692 ALLDEPFILES_SUBDIR. List all the nindy and vxworks subdir files
3694 (TAGFILES_MAINDIR): Change ALLDEPFILES to ALLDEPFILES_MAINDIR.
3695 (gdb.tar.Z): Use ALLDEPFILES_SUBDIR as well as SFILES_SUBDIR.
3697 Mon Feb 25 16:02:35 1991 Cygnus John Gilmore (cygnus at oldman)
3699 * am29k-tdep.c: Add contribution line.
3700 (examine_prologue): Cache information about function prologues in
3701 the misc-function-vector to avoid lots of references over the
3702 serial line while examining instructions.
3704 * core.c (core_close): New function made from cleanup_core.
3706 * core.c, exec.c, inftarg.c, remote-eb.c, remote-nindy.c,
3707 remote-vx.c, remote.c, target.c, target.h,
3708 Update target_ops vector to add attach, close, and load entries.
3709 Use add_syms_addr_command, not add_file_addr_command, for
3710 add_file. Break out close routine from existing code.
3712 * dbxread.c (really_free_pendings): Don't free pending_blocks;
3713 they are in an obstack.
3714 (read_dbx_symtab): Relocate end_of_text_addr in the psymtab.
3716 (define_symbol): Add symbol type parameter; change callers;
3717 pass type parameter to DBX_PARM_SYMBOL_CLASS macro to allow
3718 it to influence the symbol class on the i960.
3719 (define_symbol): Swap LOC_CONST's into target byte order.
3721 * exec.c (exec_close): New function.
3722 (exec_file_command): Call it.
3724 * findvar.c (read_relative_register_raw_bytes): Doc byte order,
3725 Fix byte order of frame pointer.
3726 (read_var_value): Result of 0 if var's value can't be found,
3727 e.g. missing FRAME_ARGS_ADDRESS. Byte-swap LOC_CONST and
3728 LOC_LABEL values to target order. Add LOC_LOCAL_ARG.
3729 (locate_var_value): Use read_var_value and use its lazy address
3730 as the location of the var's value. Lint.
3732 * i960-pinsn.c (next_insn): Add routine from vxgdb for scanning
3735 * i960-tdep.c (arg_address, i960_frame_find_saved_regs): Remove
3736 obsolete Intel versions in favor of vxgdb versions.
3737 (check_host, byteswap, byteswap_val, reorder_val): Eliminate
3738 code dealing with byte order of values, which Intel did in host byte
3739 order rather than gdb-4's target byte order.
3740 (i960_frame_chain_valid): Move to nindy-tdep.c.
3741 (examine_prologue, skip_prologue, frame_find_saved_regs,
3742 frame_args_address, leafproc_return, saved_pc_after_call,
3743 pop_frame): Add vxgdb versions from Mark Fox.
3744 (examine_prologue, frame_struct_result_address): Add code
3745 to deal with the saved value of G13 (struct return address
3747 (frame_args_address): Modify Mark's version to prefer the
3748 saved value over the current value in the topmost frame.
3749 Cache result in the frame info to avoid performance hair in
3751 (print_fault): Add gdb960 code for printing faults.
3752 (_initialize_i960): Actually call check_host.
3754 * ieee-float.c (ieee_extended_to_double, ieee_double_to_extended):
3755 add stub routines. FIXME, these currently just return zero!
3757 * infcmd.c (program_info): Use PRINT_RANDOM_SIGNAL.
3758 (attach_command): Call target_attach, not target_open, now.
3760 * infrun.c (normal_stop): Make global, not static, for vx_attach.
3761 (child_attach): Rename from child_open.
3762 (wait_for_inferior): Use PRINT_RANDOM_SIGNAL. If stop_pc is zero,
3763 don't confuse it with a zero step_resume_break_address.
3765 * inftarg.c (child_detach): Eliminate inferior_pid test.
3766 (child_files_info): Clean up message a bit.
3767 (child_ops): Use child_attach, not child_open, to attach.
3769 * mem-break.c: #ifdef out the whole file if BREAKPOINT is not
3770 set (e.g. on VxWorks or NINDY). Move read_memory_nobpt from
3771 findvar.c to here, since it depends on the contents of the
3772 shadow_contents of breakpoints, but keep if #if 0 since it is
3775 * nindy-tdep.c: New file, contains nindy_frame_chain_valid, moved
3778 * printcmd.c (address_info): Handle LOC_LOCAL_ARG. Lint.
3779 (ptype_command, display_command): Eliminate have_inferior_p and
3780 have_core_file_p in favor of target_has_stack or
3781 target_has_execution.
3782 (print_frame_args): Handle LOC_LOCAL_ARG. Eliminate duplicate
3783 code for actually finding the values of arguments, though we still
3784 keep track of the maximum stack offset for use in printing unnamed
3785 arguments. Handle missing FRAME_ARGS_ADDRESS.
3787 * remote-nindy.c (i960_print_fault): Move to i960-tdep.c.
3788 (struct nindy_regs): Define registers passed to/from nindy.
3789 (nindy_fetch_registers, nindy_store-registers): Translate between
3790 nindy and GDB formats for the registers.
3791 (dcache_init): Statically allocate the cache, since it was being
3792 allocated by a malloc that was never freed anyway.
3793 (nindy_create_inferior): Error, not core dump, if no exec file.
3794 (nindy_before_main_loop): Use target_load, not target_add_file.
3796 * remote-vx.c (net_load): Specify large timeout for load
3797 requests. Allow user to break out with INTERRUPT.
3798 (net_break): Remove useless code, clean up. Change callers.
3799 (parse-args, skip_white_space, find_white_space): Clean up arg
3800 parsing to cope with quoted strings.
3801 (net_wait, net_quit): Never call error, just return status.
3802 (vx_read_register, vx_write_register): Cleanup status checking.
3803 #ifdef the code based on which CPU we are using (960 or 68k),
3804 FIXME, this should be completely general but it isn't yet.
3805 (vx_xfer_memory, vx_resume): Cleanup status checking.
3806 (vx_run_files_info): Improve message.
3807 (vx_load_command): Renamed from vx_add_file_command. Allow load
3809 (net_ptrace): Remove unused routine.
3810 (vx_wait): Adopt code from vxgdb960 to cope with broken
3811 connections to target machine and prompt to disconnect. Remove
3812 debug printouts. Map some EVENT_'s to SIGnals.
3813 (add_symbol_stub, vx_open): Print names of object files we found,
3814 and "ok" if we read their symbols OK. Clarify output in general.
3815 (vx_attach, vx_detach, vx_kill): Add these commands.
3816 (vx_convert_from_virtual, vx_convert_to_virtual): Simplify.
3817 (vx_run_ops): Turn off all_mem, to avoid spurious msg in the
3818 "info files" output, and create_inferior, since we already have
3821 * stack.c (frame_info): Replace Frame_unknown with 0.
3822 (print_frame_arg_vars): Handle LOC_LOCAL_ARG.
3823 (return_command): Pop until the PC matches as well as the FP,
3824 so it works even if the FP is shared with another function,
3825 as in "frameless" or "leaf" procedures.
3827 * symfile.c (load_command): renamed from add_file_target_command.
3828 (add_syms_addr_command): renamed from add_file_addr_command.
3829 (add_syms_command): Stub to call target_add_syms.
3830 (_initialize_symfile): Change command names and descriptions,
3831 add-file => add-syms, and load from alias to its own command.
3833 * target.c (kill_or_be_killed, maybe_kill_then_attach,
3834 maybe_kill_then_create_inferior): Default for attempts to start
3835 a process, if one is already running, is to ask about killing
3836 it and retry if yes.
3837 (upstack_create_inferior): #if-0 it, strata obsolete it.
3838 (push_target, unpush_target, pop_target): to_close() a target
3839 before unstacking it.
3840 (target_info): Renamed from target_files_info.
3841 (_initialize_targets): Rename "i files" as "i target", accessible
3844 * target.h: Improve comments about the target_ vectored routines.
3846 * tm-i960.h: Remove NINDY-specific stuff to tm-nindy960.h.
3847 Convert commenting style to standard GNU style.
3848 (DBX_PARM_SYMBOL_CLASS): allow LOC_LOCAL_ARG's to be recognized.
3849 (SKIP_PROLOGUE): No longer a no-op.
3850 (SAVED_PC_AFTER_CALL): Now handles leaf procedures.
3851 (*_REGNUM): Sort register numbers.
3852 (REGISTER_BYTES, REGISTER_BYTE, REGISTER_RAW_SIZE,
3853 MAX_REGISTER_RAW_SIZE, REGISTER_CONVERTIBLE,
3854 REGISTER_CONVERT_TO_VIRTUAL, REGISTER_CONVERT_TO_RAW): Float regs
3855 are now 10 byte extendeds, not 8 byte doubles.
3856 (FRAME_CHAIN_VALID): Make this config-dependent, since it differs
3857 for nindy versus vxworks targets. FIXME, this should possibly go
3858 in the target vector.
3859 (EXTRA_FRAME_INFO, INIT_EXTRA_FRAME_INFO): Cache both
3860 frame_saved_regs and arg pointer with each frame.
3861 (FRAMELESS_FUNCTION_INVOCATION): New leafproc support.
3862 (FRAME_ARGS_ADDRESS): Use cached result.
3863 (FRAME_ARGS_ADDRESS_CORRECT): New, avoids g14 guessing.
3864 (FRAME_FIND_SAVED_REGS): Change arg to subsidiary fn.
3865 (PRINT_RAMDON_SIGNAL): Call print_fault.
3866 (POP_FRAME): Now works.
3868 * tm-nindy960.h: Break this off tm-i960.h. NINDY-specific
3869 option parsing and startup; STACK_END_ADDR, FRAME_CHAIN_VALID,
3870 BREAKPOINT, and DECR_PC_AFTER_BREAK are here.
3871 (ADDITIONAL_OPTION_HANDLER): use target_load, not
3874 * tm-vxworks960.h: Break this off tm-i960.h. VxGDB specific
3875 startup; DECR_PC_AFTER_BREAK, and FRAME_CHAIN_VALID are here.
3877 * valarith.c (value_subscripted_rvalue): Avoid handling
3878 floats and doubles specially; it gave alignment errors. Lint.
3880 * valops.c (value_of_variable, value_of_this): Error if unknown
3883 * valprint.c (print_floating): Bcopy rather than pointer-deref,
3884 to avoid alignment problems.
3885 (value_print): Handle unknown value address.
3886 (cplus_val_print): Two args are ignored; remove them. Change caller.
3887 (val_print): Use unpack_long rather than pointer-deref.
3890 (unpack_long, unpack_double): Use bcopy rather than pointer-deref
3891 to avoid alignment problems.
3892 (value_being_returned): Error if return value unknown.
3893 (set_return_value): Add bogosity warning, FIXME. *
3895 * TODO: A woman's work is never done.
3897 * Makefile.dist: Distribute REMOTE_OBS into tconfig files.
3898 Separate INCLUDE_CFLAGS for use with lint. Add LINTFILES.
3899 Add ieee-float.o to OBS.
3900 * tconfig/{nindy960,vxworks68,vxworks960}: Include the desired
3901 REMOTE_OBS remote-interface files in the TDEPFILES and TM_FILE.
3902 * tconfig/i960: FIXME. Half-merge, produce warning if config'd.
3904 Changes to generalize the VxWorks RPC protocol slightly, to handle
3905 i960 as well as 68000.
3907 * vx-share/dbgRpcLib.h (VX_SOURCE_STEP): Add.
3908 * vx-share/reg.h: Produce i960 regs #ifdef I80960
3909 * vx-share/xdr_ptrace.c: Skip FPA registers if 960.
3910 * vx-share/xdr_rdb.h: Add SOURCE_STEP struct and xdr decl.
3911 * vx-share/xdr_rdb.c: Add xdr_SOURCE_STEP routine.
3912 * vx-share/xdr_regs.c: Add xdr_regs, xdr_fp_status, xdr_ext_fp
3913 for i960. Change xdr_vectors to xdr_opaques for 68k registers,
3914 so they will move in target byte order rather than network
3915 byte order (happens to be the same).
3917 Mon Feb 25 03:41:44 1991 John Gilmore (gnu at cygint.cygnus.com)
3919 * tm-convex.h (END_OF_TEXT_DEFAULT): Remove #if 0'd block.
3921 Sun Feb 24 00:55:53 1991 John Gilmore (gnu at cygint.cygnus.com)
3924 Add contribution lines to various files, showing where they
3927 * breakpoint.c (break_insn, check_break_insn_size,
3928 read_memory_nobpt): Remove to mem-break.c.
3930 * xm-*.h, param-no-tm.h, tm-29k.h, valprint.c: Change BYTE_ORDER to
3933 * tm-29k.h (STAB_REG_TO_REGNUM): Warn user if symbol table
3934 entry has bad register number. This change is not
3935 tested in this release, FIXME.
3937 * frame.h: Eliminate Frame_unknown in favor of a simple zero.
3940 * value.h: Force value's contents field to be aligned to hold
3941 at least a double or a long long (if supported). This avoids
3942 doing bcopy's in and out of the contents field.
3944 (step_1): Avoid coredump under obscure circumstances when we
3947 * symtab.h (misc_info): Add field to misc function vector for
3948 any kind of cached information the target code desires. AMD
3949 29000 uses this to avoid repeating examine_function_prologue's.
3951 * coffread.c: Lint. Remove static symfile, read_section_header.
3952 core.c (have_core_file_p): Lint: remove.
3953 expprint.c (print_subexp): Lint.
3954 infptrace.c, valops.c, valprint.c: lint.
3956 Roll in changes from vxgdb-5.0.1:
3958 * symtab.h: Comment byte order of each address class. Add
3959 LOC_LOCAL_ARG for frame-relative args (960).
3960 expread.y: Use LOC_LOCAL_ARG where LOC_ARG is used.
3961 symtab.c, symmisc.c: ditto.
3963 * infrun.c (init_wait_for_inferior): Clear stop_signal.
3965 * remote.c (remote_resume): Error if resume with a signal.
3967 * symfile.c (prim_record_misc_function): Clear misc_info.
3968 (fill_in_vptr_fieldno): Check stub type of arg.
3970 * valops.c (value_cast): Avoid looking up names of types whose
3971 name we don't know, to prevent coredump. Sun CC produces typedef
3972 rtx and the name of *rtx is zero...
3974 Mon Feb 18 21:16:25 1991 John Gilmore (gnu at cygint.cygnus.com)
3976 Roll in changes from final AMD 29000 port (Tiemann).
3978 tconfig/am29k: Add COFF_ENCAPSULATE and TARGET=TARGET_AM29K
3979 for ../include/a.out.encap.h. This might not work now that BFD
3980 is separately compiled. Instead, BFD support for encap will have
3981 to translate machine type 29k into the right COFF_MAGIC.
3983 * infcmd.c: Remove references to inferior_pid that aren't used
3984 in actual ptrace calls; use target_has_execution, etc.
3985 (have_inferior_p): Remove function.
3986 (program_info): Print target info rather than "process number";
3987 avoid gratuitous messages unless from_tty.
3988 (run_stack_dummy, finish_command): Set proceed_to_finish.
3989 infrun.c: Remove inferior_pid refs. Decl & init proceed_to_finish.
3990 main.c: Lint. Lose have_inferior_p().
3991 inferior.h (have_inferior_p): Remove, lint.
3992 (proceed_to_finish): Add flag to ask that all regs be saved
3993 by normal_stop, for the few commands that need it, speeding up
3994 serial I/O. Add comments to stop_registers.
3996 * remote-eb.c: Remove newline from breakpoint message we grep
3997 for. Never time out when running the user program.
4001 Wed Feb 13 15:34:40 1991 John Gilmore (gnu at cygint.cygnus.com)
4003 Roll in changes from vxgdb-5.0.1:
4005 * dbxread.c (read_dbx_symtab): If we encounter a "FORTRAN COMMON"
4006 symbol in its raw form, we are processing an unlinked ".o" file.
4007 See if the target environment has assigned it an address, using
4008 target_lookup_symbol (VxWorks does), and enter it into the symtab
4011 * tm-vxworks.h (FRAME_CHAIN, FRAME_CHAIN_VALID): Override usual
4012 68k versions for a simpler version that assumes zero FP at bottom.
4013 Fixes bug of truncated stack reports.
4015 * target.h (target_lookup_symbol): Define this routine's args
4016 and result, finally.
4018 * target.c (nosymbol): Default routine for target_lookup_symbol.
4019 (target_default): Default lookup_symbol and call_function too.
4020 (files_info): Only print has_all_memory warning if a non-dummy
4023 * remote-vx.c (vx_read_register, vx_convert_to_virtual,
4024 vx_convert_from_virtual): If target does not have floating point,
4025 zero register "values", and avoid doing cross-net conversions.
4026 (vx_lookup_symbol): Rename net_lookup_symbol, add to vectors.
4027 (vx_open): Rearrange code that attaches to target and reads
4028 symbols for all loaded modules, to work if some of the modules
4029 are not accessible. Add symbol_stub() and add_symbol_stub()
4030 as callbacks from catch_errors(). Allow connect attempt to be
4031 interrupted painlessly with ^C (FIXME, there are still some bugs
4032 if the interrupt happens during symbol reading.). Print
4033 final message with puts_filtered, since symbol messages are
4038 * main.c (catch_errors): Only print errstring if non-null.
4039 (command_loop): Avoid an ioctl per command to test ISATTY.
4041 * remote-vx.c (net_load): make static; avoid sophomoric msg.
4042 (vx_xfer_memory): Return correct result!
4043 (vx_files_info): Indicate whether target has float or not.
4044 (vx_lookup_symbol): Complain, not error, if target gone.
4045 (vx_open): Print "Connected" msg before disabling immediate-quit.
4046 [FIXME: lookup_symbol and vx_open changes need testing.]
4048 target.c, remote-eb.c, inftarg.c, am29k-opcode.h, target.h,
4049 tm-29k.h, tmm-vxworks68.h, symfile.c, gdb-int.texinfo: Add
4050 contributor lines and update copyrights to 1991.
4052 Changes from an attempted H-PUX host port:
4054 * infptrace.c (PT_ATTACH, PT_DETACH): Handle HP/UX, which
4055 defines PT_ATTACH and PT_DETACH but not PT_KILL.
4056 * remote-eb.c (eb_open): Misplaced endif kills sysv H/PUX.
4057 * remote-vx.c: include <sys/time.h> for HPUX.
4058 * hp300hpux-xdep.c (fetch_core_registers): Rewrite old
4059 "core_file_command" routine to BFD regime. May not work yet.
4061 Attempted port of "gdb-3.4 Van Jacobson xgdb" to modern gdb.
4063 * xgdb.c: Replace X10 version with some VJ version.
4064 (FIXME: Its copyright assignment is not on record.)
4065 * xgdb.c: Update include files to X11R4 (Xaw crud).
4066 (xgdb_display_source, create_text_widget): fix call to
4067 get_filename_and_charpos. Rewack source window stuff for X11R4
4068 (gleaned from include files, and "nm's" of binary libraries, since
4069 I had no doc available).
4070 (append_selection, append_selection_word): Disable with FIXME
4071 since R4 changed interface here.
4072 (create_buttons): Add back the old set of buttons.
4073 (xgdb_create_window): Fix call to XtInitialize (&argc not argc).
4075 * Makefile.dist (xgdb, xgdb-init.c): Update for X11R4 on Suns.
4076 Roll VERSION to 3.94 (not yet final though).
4078 Sat Feb 9 09:46:25 1991 John Gilmore (gnu at cygint.cygnus.com)
4080 * obstack.h (obstack_ptr_grow, obstack_ptr_grow_fast,
4081 obstack_int_grow, obstack_int_grow_fast): Eliminate
4082 cast on left of assignment, which gives MIPS cc fits and is
4085 * sparc-pinsn.c (print_insn): Eliminate 'set' test, subsumed by
4086 F_ALIAS. Use printf, not fprintf, when not passing a file
4088 (compare_opcodes): Check that identical instructions have
4089 identical opcodes, complain otherwise.
4091 * sparc-opcode.h (st %fsr): Fix opcode "lose" mask. This
4092 was reported by Roland McGrath.
4093 (unimp): Only match if exactly zero instruction. (Roland)
4094 (branches and traps): Generate all variations of these
4095 instructions with macros, based on a single call that defines
4096 each condition name and its binary representation.
4097 (set): Turn on alias bit, to avoid test in sparc-pinsn.c.
4099 * valprint.c (val_print_fields): Take, and use, format parameter.
4100 This means that "p/x struct" again prints the elements in the
4101 desired format. Changed callers.
4103 * stack.c (frame_info): Use filtered output, and indicate wrap
4104 points. Remove kludgy formatting designed to avoid line wrap.
4106 * utils.c (wrap_here): If the line is already full (because
4107 we had printed a long indent or long wrapped string), do an
4108 immediate newline-and-indent.
4110 * m68k-pinsn.c (print_insn_arg): Bugfix from
4111 ntmtv!thompson@ames.arc.nasa.gov (Mike Thompson): 'bkpt #0'
4112 instruction is incorrectly disassembled as bkpt #8.
4114 * dbxread.c (end_psymtab): Bugfix from Peter Schauer
4115 <pesrem@regent.e-technik.tu-muenchen.de>: If you want to set a
4116 breakpoint in a *.y file gdb will say Reading in symbols for *.y...
4117 and then will dump core (sometimes). I traced it back to an
4118 uninitialized symfile_name in psymtab_to_symtab.
4119 (const_vol_complaint): Add quotes to message.
4120 (define_symbol): Only believe line number if gcc_compiled.
4121 Avoid allocating symbol if we will not return it.
4123 Add target strata support so that newly established targets go
4124 into their right place in the target stack (e.g. a new exec file
4125 doesn't wipe out the ability to access the running process).
4127 * target.h, core.c, exec.c, inftarg.c, remote-eb.c,
4128 remote-nindy.c, remote-vx.c, remote.c, target.c: Add to_stratum
4129 and initialize it properly in all the targets.
4131 * target.h: Document strata. Change return type of push_target.
4133 * target.c (nomemory): new function for dummy memory access.
4134 (tcomplain): Rename complain, now also used in symfile.c.
4135 (push_target): Push targets within strata. New return value shows
4136 whether new target is on top of stack or not. Always keep dummy
4138 (target_files_info): Ignore dummy target.
4140 * core.c (core_open): Warn user, and skip accessing file, if the
4141 core target is not the topmost target in the stack.
4142 * remote-nindy.c (nindy_create_inferior): Avoid unpush_target, now
4145 * remote-vx.c: Remove vx_prepare_to_store from vxworks memory
4146 target_ops, it doesn't belong there since we have no regs there.
4147 Change name of target from machine => memory to clarify.
4149 Thu Feb 7 16:32:09 1991 John Gilmore (gnu at spiff.cygnus.com)
4151 * Freeze version 3.93 for release.
4153 * Makefile.dist: Handle vx-share and nindy-share subdirs
4154 properly when building gdb.tar.Z.
4156 * symtab.c: lint; add no_symtab_msg to consolidate the messages
4157 printed in various places, so I could change just one copy.
4159 * dbxread.c, coffread.c: Change references to bfd->iostream
4160 to cast to FILE *, now that BFD avoids needing types defined
4161 in other header files.
4163 Tue Feb 5 21:39:35 1991 John Gilmore (gnu at cygint.cygnus.com)
4165 * command.c, dbxread.c, expprint.c, infcmd.c, infptrace.c,
4166 infrun.c, printcmd.c, remote-nindy.c, source.c, sparc-tdep.c,
4167 sparc-xdep.c, symfile.h, symmisc.c, utils.c, valprint.c: Lint
4168 (actually gcc -Wall).
4170 * dbxread.c: Remove first_global_sym, last_global_sym, since
4171 they are never referenced.
4173 * defs.h (baud_rate): Declare.
4174 main.c: Define it, and add the -b option to set it.
4176 * gdb-int.texinfo: Add text on how to define a new host or target
4177 architecture, prompted by Per Bothner's questions about MIPS
4180 * gdb.texinfo: Document "complaints". Change doc of -q since
4181 gdb no longer prints the copyright and blurb if you specify a file
4182 name to be debugged (just like Emacs). Add doc for Nindy-specific
4183 command line flags for specifying target serial port and such.
4184 Update copyright to 1991.
4186 * gdbcore.h: Remove a large mass of now-useless crud, since BFD
4187 has taken over for us the job of ripping up executable files. The
4188 crud caused Per Bothner's port to not compile.
4190 * infrun.c (normal_stop): Avoid printing "Program exited
4191 normally" if we are in batch mode. This allows a GDB which
4192 executes a program on a target system, to behave like a Unix
4193 command (input from stdin, output to stdout, no extraneous
4196 * main.c (main): Allow additional machine-dependent command line
4197 options to be specified with the ADDITIONAL_OPTIONS,
4198 ADDITIONAL_OPTION_CASES, ADDITIONAL_OPTION_HELP, and
4199 ADDITIONAL_OPTION_HANDLER macros. Also allow machine-dependent
4200 processing to occur just before the main loop with
4201 BEFORE_MAIN_LOOP_HOOK.
4202 (main): If a "core file" argument is specified, and it is not a
4203 core file, try it as a process ID to attach.
4204 (symbol_completion_function): Attempt to cope with
4205 "show screen-" TAB, not very successfully. This needs more work,
4207 (batch_file): New function, returns whether we are reading
4208 commands from an interactive tty on stdin, or from somewhere else.
4209 Called by normal_stop since it doesn't get from_tty passed down
4210 to it like many commands do.
4212 * remote-nindy.c: Handle command line options for nindy
4214 (nindy_before_main_loop): Prompt user for tty name if they
4215 don't specify it before getting to the interactive command loop.
4217 * tm-i960.c: Add ADDITIONAL_OPTIONS, etc, to handle -O, -brk,
4218 and -r command line options. Also add hook before main loop
4219 to make it easy to specify a tty.
4221 * TODO: More things to do, one done.
4223 Mon Feb 4 23:57:39 1991 John Gilmore and Mike Tiemann (at cygint.cygnus.com)
4225 * dbxread.c: Make complaint() calls pass pointer, not struct.
4226 Add complaints about badly formatted C++ type information
4227 (const/volatile indicator, and parse errors resulting in
4228 error_type). Fix C++ virtual member fn comment.
4229 (read_struct_type): Avoid bumping pointer if we got a parse
4230 error; this prevents our walking beyond the end of a string.
4231 Terminate loop on null char as well as semicolon.
4232 (process_one_symbol): Fix the LBRAC fix so that it uses the
4233 last previous SLINE, FUN, or SO record's PC address. C++ debug
4234 symbols did not have SLINE records in a useful order compared
4235 to the LBRAC records.
4236 (define_symbol): Handle "catch" records.
4238 * symtab.c (check_stub_type): Added new complain
4239 `stub_noname_complain' and added a consistency check to
4240 keep the debugger from crashing when finishing from an
4241 exception frame. A real fix will be needed later.
4243 Sat Feb 2 10:43:05 1991 John Gilmore (gnu at cygint.cygnus.com)
4245 * infcmd.c (attach_command): Make global.
4247 * Makefile.dist (REMOTE_OBS): Make these compile by default,
4248 but make them easy to comment out. Perhaps later they should
4249 be enabled by what CPU you configure for? FIXME.
4250 (VERSION): Roll to 3.93.
4251 (pinsn.o): Remove rule for obsolete file.
4252 (dbxread.o,coffread.o,mipsread.o): Use ${srcdir} explicitly.
4254 Run down a problem that manifested by printing the wrong function
4255 name in stack traces of read_ofile_symtab. Turned out that the
4256 problem was the SunOS 4.1.1 (and previous) C compiler outputs
4257 the LBRAC symbol with an address in the *data* segment, which
4258 blew our binary search through the blocks.
4260 * dbxread.c: Use the complain() facility consistently to bitch
4261 about problems in the symbol file we are reading.
4262 (finish_block): Add code to check the nesting of the blocks;
4263 complain and Procrust them to fit if wrong.
4264 (make_blockvector): Check the order of the blocks, complain
4265 [but don't cope] if wrong.
4266 (process_one_symbol): ifndef SUN_FIXED_LBRAC_BUG, check LBRAC
4267 symbols to be sure their PC value is greater than the last SLINE
4268 (line number) symbol we've seen, complaining and adopting the
4269 SLINE PC value if wrong.
4271 * symfile.h (struct complaint, complaint_root, complain,
4272 clear_complaints): Add.
4273 * symfile.c (complain, complaint_root, clear_complaints): Add
4274 facility to deal with non-fatal complaints and to regularize their
4276 (symbol_file_add): Clear complaint counters to allow new complaints.
4277 (initialize_symfile): Add 'set complaints' and 'show complaints'.
4279 * dbxread.c (dbx_symfile_read): Remember the address and size
4280 of the string table for the main symbol file, so we won't read it
4282 (dbx_psymtab_to_symtab): Fix the check for main symbol file,
4283 to avoid reading the string table yet again. Lint.
4284 (throughout): Improve filtered output, including word wrap.
4285 (read_range_type): Improve Bothner's fix to handle other types too.
4287 * utils.c: Improve line wrap implementation. Handle unlimited
4288 width by making chars_per_line unsigned.
4289 (puts_filtered): New, easy, function.
4291 * defs.h (puts_filtered): add.
4293 * mipsread.c (compare_symbols, sort_symtab): Remove these fns,
4294 call the identical sort_symtab_syms() in symfile.c instead.
4296 * expread.y: Suggest the `file' command rather than `symbol-file'.
4298 * command.h (enum var_types): Add zinteger for seroable
4300 * command.c (do_setshow_command): Handle var_zinteger. Restructure
4301 nested if's into a switch.
4303 * breakpoint.c (bpstat_print): If bpstat "print" flag is not set,
4304 we did not stop because of a breakpoint (it must have been for
4305 some other reason, like a "stepi"), so don't print anything.
4307 * symtab.c: Include <sys/types.h> all the time. Now that BFD
4308 doesn't include <sys/types.h>, old SunOS's require it for
4311 Sat Feb 2 10:39:15 1991 Per Bothner (bothner@cs.wisc.edu)
4313 A test port of gdb-3.92.6 to the Sony NEWS.
4316 Don't normally link in remote- or vx stuff.
4317 Some of it doesn't compile, and it wastes space for 99% of the users.
4318 Remove reference to no-longer-used HAVE_VPRINTF.
4319 Fixed BFD_DEP typo to BFD_DIR.
4321 Fix cast in arg to bfd_h_getlong.
4322 Make char *prefix be const.
4323 Fix how certain range types are mapped into builtin unsigned int types.
4325 Remove 2 #includes. They cause errors (on Sony, at least),
4326 and aren't needed (they wern't in earlier versions).
4328 print_address_symbolic should never demangle labels
4329 (since it prints *assembler-level* labels).
4331 [This was superseded by the change to printcmd below.]
4334 Add some "volatile" return types to avoid warnings.
4335 If MISSING_VPRINTF add vprintf function and not just macro
4336 (since vprintf is used in printcmd.c).
4338 Unless __GNUC__, use obstack_grow instead of obstack_ptr_grow.
4339 (The latter isn't grokked by some PCC-based compilers.)
4341 [This change is in abeyance, we prefer to fix obstack_ptr_grow.]
4343 Make chunk size of dont_print_obstack 32*4 instead of default 4096.
4344 * nindy-share/coffstrip.c
4345 Added some forward declarations (otherwise, gcc complains
4346 about implicit extern redefined as static).
4348 Sun Jan 20 02:38:19 1991 John Gilmore (gnu at cygint.cygnus.com)
4350 Changes inspired by Per Bothner:
4351 * printcmd.c (print_address_symbolic): Take additional parameter
4352 specifying whether to demangle.
4353 (print_address): Pass in asm_demangle to control demangling.
4354 (print_address_demangle): New fn, takes explicit arg to control
4356 * utils.c: Add new vars demangle and asm_demangle, and let them
4358 (fputs_demangled): If !demangle, just print the argument.
4359 (fprint_symbol): If !demangle, just print raw symbol.
4360 * valprint.c (val_print): Call print_address_demangle rather than
4361 print_address, to cause demangling to depend on the global
4362 rather than assembler-level demangling setting.
4363 * WHATS.NEW, gdb.texinfo: Document.
4365 * main.c (show_command): Show all settings if no arg.
4366 (initialize_main): Make "info set" the same as naked "show".
4367 * command.c (cmd_show_list): Handle prefix commands in the
4368 list, and print the name of the setting as well as its English
4369 description and value.
4371 Allow gdb functions to specify where a line should wrap if it
4372 exceeds the size of a terminal line. Use it to make the output
4374 * utils.c (set_screen_width_command): New fn, mallocs a buffer
4375 of the right size when screen width changes.
4376 (set_screensize_command, screensize_info): Remove #if 0'd fns.
4377 (wrap_here): New fn, indicates a point in the output where we
4378 should wrap the line rather than just letting it overflow at a
4380 (fputs_filtered): Implement wrapping.
4381 (n_spaces): New fn, returns a pointer to N spaces.
4382 (print_spaces_filtered): Use n_spaces.
4383 * defs.h (n_spaces): Declare.
4384 * stack.c (print_frame_info): Wrap with 4-space indent after
4385 fn name and before filename and line number.
4386 * printcmd.c (print_frame_args): Wrap with 4-space indent
4387 before each argument name is printed.
4388 * valprint.c (value_print): Wrap with no indentation before
4390 (val_print_fields): Wrap with indentation relative to nesting
4391 level before each field name.
4392 (val_print): Wrap with nesting indentation before array elements.
4393 * command.c (do_setshow_command): Avoid extra newlines,
4394 wrap with 4-space indent around values printed, end with period.
4395 * WHATS.NEW, gdb.texinfo, gdb-int.texinfo: Document.
4397 * breakpoint.c (breakpoint_1): Implement addressprint for
4398 "info breakpoints" display. Change file name and line number
4399 format to " at file:nnn" rather than " (file line nnn)".
4400 * gdb.texinfo: Document.
4403 Fri Jan 18 07:21:25 1991 John Gilmore (gnu at cygint.cygnus.com)
4405 Frozen for gdb-3.92.6 release.
4407 README, WHATS.NEW: Update for 3.92.6 release.
4409 tconfig/{altos, i386v, i386v32, m88k, umax}: Eliminate
4410 coffread.o from configs since it is now built by default.
4411 tconfig/{3b1, altosgas, arm, convex, hp300bsd, hp300hpux,
4412 i386v-g, i386v32-g, isi, merlin, news, news1000, np1, pn,
4413 pyramid, symmetry, vax, vxworks68}: Eliminate dbxread.o
4414 from configs since it is now built by default.
4416 Makefile.dist: Update for release 3.92.6. Handle files that
4417 have been moved to ../include, ../getopt, or ../bfd. Add
4418 saber.suppress and tests directory. Add config.status to
4419 the release (it will say "none").
4421 coredep.c: Minor formatting fixes.
4423 These changes were made in early December but only checked in now:
4424 * nindy-share/Onindy.c, nindy-share/coffstrip.c,
4425 nindy-share/nindy.c: lint
4426 * nindy-share/nindy.c (ninStopWhy): Don't byteswap the
4427 register values coming back from the target; we store values
4428 in target byte order everywhere.
4430 Wed Jan 16 19:01:37 1991 John Gilmore (gnu at cygint.cygnus.com)
4432 * am29k-opcode.h, am29k-pinsn.c: Add 29050 opcodes.
4434 * valprint.c (cplus_val_print, val_print_fields): New functions,
4435 which print C++ objects. They conspire to avoid printing a
4436 virtual base class more than once, following all the twists and
4437 turns of C++ virtual base rules.
4438 (val_print): Call the above rather than do it by hand.
4440 * symfile.c (symbol_file_add): Only reset symfile_mtime for main
4441 symbol file, not for added files like shared libs. This really
4442 needs to be generalized to a timestamp per file.
4444 * core.c (cleanup_core): Avoid coredump if no core file.
4446 * config.gdb: Accept -host or -target in place of +host or
4449 * coffread.c (find_linenos): Avoid desupported BFD interface
4450 to line numbers. We still read them manually rather than using
4451 BFD's "generic" features.
4453 * gdbrc.tex, threecol.tex: Add GDB reference card and its
4455 Makefile.dist: Add refcard to OTHERS list for creating tar files.
4457 * Makefile.dist: Eliminate use of $< in explicit targets.
4459 * readline/Makefile: Use $< rather than $*.c, which does not
4460 include the VPATH in GNU Make.
4462 * tconfig/i960-bout, tconfig/i960-coff: These are identical
4463 copies of tconfig/i960, added for global configuration
4464 compatability. All i960 versions can read both coff and b.out.
4466 * tm-88k.h: Fix multiline macro that lacked \'s. Remove
4467 COFF_FORMAT and COFF_CHECK_X_ZEROES since these are now handled
4470 * TODO: Think of more things to do.
4472 Wed Jan 2 19:09:29 1991 John Gilmore (gnu at spiff.cygnus.com)
4474 tconfig/{am29k,i960,sun2*,sun3*,sun4*}: Eliminate config
4475 of sdb versus dbx debug symbols. Add kludge for 68881 80-bit to
4476 64-bit float conversion.
4478 tconfig/sun4, tconfig/sun3, xconfig/sun4, xconfig/sun3: Make
4479 equivalent to sun?os4 so global config works.
4481 Wed Jan 2 18:20:51 1991 John Gilmore (gnu at spiff.cygnus.com)
4483 Fix from Eberhard Mattes <mattes@azu.informatik.uni-stuttgart.de>
4485 * main.c: Only declare linesize once; declare pagesize not at
4486 all, since it is never used.
4487 (main): Clear newly allocated line before it is used.
4489 Fri Dec 28 00:13:42 1990 John Gilmore (gnu at cygint)
4491 Further stabilization for the Intel 960.
4493 * Makefile.dist: Parameterize the location of the "include"
4494 and "bfd" directories, as well as "getopt". Add symfile.c.
4495 Link in both dbxread and coffread. Fix up "make depend" to
4496 rewack the locations of include, bfd, and getopt in its output.
4498 * README: Document moving include files, improve some of
4501 * coffread.c: Move common code out to symfile.c. Change
4502 symbol_file_command style interface to use new *_symfile_init
4503 and *_symfile_read interface under BFD. Use BFD internal
4504 info to locate line table, symbols, etc.
4506 * core.c (core_fetch_registers): Rename to get_core_registers
4507 to avoid confusion with fetch_core_registers.
4508 (register_addr): Move to coredep.c, which is already machine
4509 dependent. This leaves core.c pretty clean of dependencies.
4511 * coredep.c (register_addr): Accept this routine from core.c.
4513 * dbxread.c: Move common code (with coffread.c, etc) into new
4514 symfile.c. Each psymtab now contains a pointer to the
4515 format-dependent function that knows how to read it in. Make
4517 (dbx_psymtab_to_symtab): Renamed from psymtab_to_symtab_2.
4518 (process_one_symbol): Add code to complain about a "compiler bug
4519 we muzzle here", if we actually see it.
4521 * eval.c (evaluate_subexp): Insert missing "break" statements
4522 in code that determines whether a variable is an lvalue in
4523 memory, register, or whatever. I detected this via a compiler
4524 bug in which it *almost* mashed out the whole switch statement.
4526 * gdb-int.texinfo: Add minor sections on configuring gdb for
4527 release, and about the README file.
4529 * infcmd.c (registers_info): Fix formatting somewhat. Still
4530 not as pretty as before, but it handles byte swapping.
4532 * remote-nindy.c: If data cache routines are interrupted while
4533 waiting for the remote end, be sure that any uninitialized cache
4534 blocks are on the free list, not on the valid list!
4536 * symfile.h: Flesh out this header file with all the various
4537 routines and variables that have been merged in from dbxread.c
4538 coffread.c, and symtab.c to symfile.c.
4540 * symfile.c: New file, containing code common to dbxread.c,
4541 coffread.c, and some code from symtab.c. All generic code for
4542 reading symbol files should be in here now.
4543 (unrecord_misc_function): Remove unused function.
4545 * symtab.h: Remove file-reading things to symfile.h.
4547 * symtab.c: Remove file-reading things to symfile.c.
4549 * tm-i960.h: Fix FRAME_CHAIN types; define PRINT_RANDOM_SIGNAL
4550 to decode i960 fault types.
4552 * target.h, remote.c, remote-eb.c, remote-vx.c, remote-nindy.c,
4553 target.c: Change type of the "resume" function from int to void,
4554 since its result was never used.
4556 Sat Dec 22 02:51:40 1990 John Gilmore (gnu at cygint)
4558 * main.c: Replace "stupid" with "caution"; you now "set caution
4561 * printcmd.c (print_scalar_formatted): Fix typo in 'g' format
4563 * infcmd.c (do_registers_info): Call val_print to deal with the
4564 byte order of the registers being printed. FIXME, this makes
4565 the formatting of the output uglier.
4567 * infcmd.c (wait_for_inferior): If PRINT_RANDOM_SIGNAL is
4568 defined, call it for signals the debugger doesn't itself use.
4569 The i960 uses this for more detailed fault information.
4571 * remote.c (remote_open): If arg is null, print help rather than
4574 * sparc-xdep.c (register_valid): Avoid declaring size, since
4575 various modules will think of various sizes depending on the
4576 architecture of their tm-file. FIXME, we need protection against
4577 actually entering one of those modules, which would clobber
4578 storage if not for the target architecture compiled into gdb.
4580 * stack.c (up_command, down_command): Always print the frame
4582 (up_silently_command, down_silently_command): New commands
4585 * i960-pinsn.c (reg), i960-tdep.c: Lint.
4587 * i960-tdep.c (i960_frame_chain_valid): Lookup_symbol now takes
4588 more parameters than it used to.
4590 * findvar.c (registers): Increase slop to 256 bytes, which should
4591 protect us against even most RISC machines with large register
4593 (locate_var_value): Move declaration inside related ifdef.
4595 * remote-nindy.c (): Use TIOCSETN rather than TIOCSETP
4596 throughout, to avoid throwing away buffered input from the board.
4597 (nindy_wait): Supply_register takes addr_of_value, not value.
4598 (i960_print_fault): Renamed from i80960_fault.
4599 (nindy_fetch_registers): Avoid have_regs stuff, just get them.
4600 (nindy_store_registers): Avoid regs_changed stuff, just stuff
4602 (nindy_create_inferior): Don't bother to write PC_REGNUM since
4603 we can set the PC in the call to proceed(). Unpush nindy_ops
4604 before pushing it on top, to avoid message to user. Eliminate
4605 commentary from Unix machines that just misleads here.
4606 (reset_command): Fix error message to suggest target command.
4608 Wed Dec 19 11:03:56 1990 John Gilmore (gnu at cygint)
4610 Release 3.92.5 as frozen.
4612 Stabilize the merged release...with help from lint, Saber C,
4615 Everywhere: Add include files needed to declare return types
4616 of functions called.
4618 * gdb.texinfo: Roland Pesch is documenting gdb, glory be!
4620 * breakpoint.h: Add undeclared breakpoint functions, and some
4621 functions for display handling since I couldn't think of a better
4624 * breakpoint.c (insert_breakpoints): Make code for disabling
4625 shared library bkpts more likely to work. It's used when we
4626 rerun a program and stop before the shared library has been
4628 (breakpoint_cond_eval, bpstat_stop_status): Pass arg as int,
4629 cast from pointer, so it squeezes through catch_errors.
4630 (bpstat_stop_status): Fix logic broken some time ago. We now
4631 always create a bpstat if the stop address matches a breakpoint,
4632 even if we don't stop there -- just like the old code used to do
4633 before I got my fingers into it (sigh).
4634 (breakpoint_1): Print "ignore count" after "stop only if"
4635 condition, since that's how it actually works.
4636 (mention): Handle watchpoints as well as breakpoints.
4637 (watch_command): use set_raw_breakpoint and mention to do most
4638 of the work (and initialize all the fields!). Only pass one
4639 arg to parse_c_expression, since that's all it takes.
4641 * command.c (not_just_help_class_command): Rename arg to args
4642 since we ignore "unused argument" warnings on vars named "args".
4643 inflow.c (child_terminal_info): ditto.
4644 infptrace.c (kill_inferior): ditto
4645 main.c (catch_errors, version_info, quit_command, pwd_command,
4646 source_command, dump_me_command, editing_info,
4647 set_history_size_command, set_history, show_history,
4649 stack.c (locals_info): ditto
4650 target.c (target_files_info): ditto
4651 valprint.c (set_input_radix, set_output_radix): ditto
4653 * core.c: Remove old variables for handling core and exec file
4654 sections (data_start, data_end, stack_start, stack_end,
4655 reg_stack_start, reg_stack_end, reg_stack_offset, text_start,
4656 text_end, exec_data_start, exec_data_end, text_offset,
4657 exec_data_offset, data_offset, stack_offset). They're
4658 superseded the more general build_section_table and
4660 (get_exec_file): Mention the `file' command.
4661 (read_memory_check): Rename to memory_error, and only call it
4662 in the case of an actual error.
4663 (read_memory, write_memory): call memory_error.
4664 (core_fetch_registers): Register section name is ".reg".
4666 coredep.c: Remove a bunch of crud now that all this file does
4667 is pull the registers out of a core file.
4668 (fetch_core_registers): Rewrite to actually work, I hope.
4670 dbxread.c: Use a.out.gnu.h, not system a.out, now.
4671 Replace index() with strchr(). Remove all the pre-BFD macro
4672 definitions for accessing the symbol file.
4673 (struct dbx_symfile_info): Encapsulate the information that
4674 dbx_symfile_init needs to pass to dbx_symfile_read in this
4677 (dbx_new_init, dbx_symfile_init, dbx_symfile_read,
4678 dbx_symfile_discard): Rearrange symbol file reading to divide
4679 the format-specific part from the format-independent part,
4680 leaving the format-independent part such as file name expansion
4681 and opening in symtab.c. This replaces
4682 partial_symbol_file_open and partial_symbol_file_read.
4683 Symbol_file_read, add_file, add_file_target_command,
4684 add_file_addr_command move to symtab.c. Pass an explicit
4685 "mainline" flag for when reading the main symbol table, rather
4686 than relying on the offset address to be zero or nonzero.
4688 (dbx_symfile_read): Don't allow void *'s to be printed as
4690 (SWAP_SYMBOL): Use bfd routines to byte-swap the symbols.
4691 (ADD_PSYMBOL_TO_LIST): Make the "function call rather than
4692 macro" debug version really work.
4693 (read_dbx_symtab): Remove unref'd parameter inclink.
4694 Avoid swapping N_SLINE symbols, for speed.
4695 Merge N_TEXT!N_EXT case with the other external symbol
4696 definitions' case. Add comments.
4697 (start_psymtab): Allocate the symfile name in the psymtab on
4698 the psymbol_obstack, rather than using the caller's storage.
4699 (end_psymtab): Only allocate a dependencies list if there are
4701 (psymtab_to_symtab_2): Use BFD when reopening file to read
4702 its symbols for real.
4703 (read_struct_type): Add FIXME comments where it needs work
4705 (read_huge_number): Add FIXME about overflows.
4706 (read_range_type): Add FIXME about comparing a long to 1<<32.
4708 * coffread.c: Minor changes to move things closer to the new
4709 regime with symtab.c and dbxread.c Major work is still needed
4712 * exec.c (exec_file_command): Remove old variables (see core.c
4714 (xfer_memory): If memory transfer is right at the end of a
4715 section, don't lose.
4717 * findvar.c (get_saved_register): If value is in a real
4718 register, LVAL is lval_register, not lval_memory.
4720 frame.h: Declare print_sel_frame and record_selected_frame.
4722 gdb-int.texinfo: New file, for GDB internals documentation.
4723 Very simple, unformatted doc of cleanups is there for now.
4725 gdbcore.h: Remove obsolete variables that described a.out
4726 section addresses and offsets. (See core.c above.)
4727 Declare fetch_core_registers and registers_fetched.
4729 getopt.c: Declare char *alloca(); even on SPARC.
4731 infcmd.c (run_command): Call target_kill rather than
4733 (step_command, next_command, stepi_command, nexti_command):
4734 Declare from_tty parameter even though we don't use it.
4735 (run_stack_dummy): argument BUFFER is a char array, not
4736 a pointer to REGISTER_TYPE.
4737 (finish_command): using_struct_return needed a value *,
4738 not a struct symbol *.
4740 * infptrace.c (child_xfer_memory): To avoid dependency on
4741 where sections are in memory, try PT_WRITE_D and if that fails,
4742 try PT_WRITE_I. Most Unixes don't care which you use.
4744 * infrun.c (step_resume_break_shadow): Change to array to
4745 match other breakpoint shadow storage.
4746 (clear_proceed_status): Pass address of bpstat to
4747 bpstat_clear, not the bpstat itself.
4748 (child_create_inferior): FIXME comment about if the child
4750 (start_inferior): Remove old function.
4751 (child_open): Use target_kill rather than kill_inferior.
4752 (wait_for_inferior): Ditto.
4753 (insert_step_breakpoint, remote_step_breakpoint): Use
4754 new step_resume_break_shadow.
4756 * inftarg.c (child_wait): If all child processes die,
4757 pretend that the one being waited for exited with signal 42.
4759 * main.c (command_line_input): When scanning for comments,
4760 don't coredump on unclosed quotes.
4761 (quit_command): Use target_kill rther than kill_inferior.
4762 (_initialize_main): Rename class_user from "user" to
4765 * printcmd.c (print_command_1): Initialize "fmt" if no format
4766 is specified by the user.
4767 (print_frame_args): Only add to args_printed if we are
4768 actually fetching args from the stack (avoiding undefined
4770 (_initialize_printcmd): Remove bogus \{ from string.
4772 * remote-eb.c (eb_open): Avoid coredump on no argument.
4774 * remote-nindy.c: Bring out of Intel environment into new
4775 target environment. Remove all conditional compilation on
4776 I80960. Massive hacking throughout.
4777 (nindy_xfer_inferior_memory): New routine stolen from
4779 (nindy_create_inferior): New routine pieced together, probably
4780 not quite working yet.
4781 (nindy_ops): New target_ops struct for nindy.
4783 * remote-vx.c: Use write_memory rather than target_write_memory
4784 to get error checking.
4785 (vx_add_file_command, vx_open): Use symbol_file_add rather than
4787 (vx_create_inferior): Use target_terminal_ours...
4789 * signame.c (_initialize_signame): Always initialize, since
4790 we need the table for things other than psignal.
4792 * solib.c (solib_add): Use symbol_file_add, not add_file.
4793 (solib_address): Return boolean result rather than struct
4794 pointer which nobody else knows the type of.
4796 * sparc-tdep.c, valops.c: Use write_memory rather than
4797 target_write_memory, to get error checking.
4799 * stack.c (locals_info, catch_info, args_info,
4800 get_selected_block, frame_command, up_command): Use
4801 target_has_stack, rather than have_inferior_p or
4804 * sun3-xdep.c (fetch_core_registers): Rewrite for new BFD regime.
4806 * symfile.h: New file, defining the interface between the
4807 generic and object-file-specific symbol reading code.
4809 * symtab.c: Move generic symbol-reading interface to symtab.c,
4810 from dbxread.c, coffread.c, mipsread.c, etc. Add symtab_fns
4811 table to map BFD targets to symbol-reading modules in GDB.
4812 Change index to strchr.
4813 (lookup_struct_elt_type): Use error() rather than hand-made
4814 simulations thereof.
4815 (lookup_partial_symbol): Speedup slightly when length == 0.
4816 (symbol_file_add): New function.
4817 (symbol_file_command): Call it.
4818 (symfile_open, symfile_init): New function.
4819 (add_file_target_command, add_file_addr_command): moved from
4822 * target.c (target_command): use target_kill.
4824 * target.h (target_files_info): Don't declare, never called
4827 * tm-sun2.h, tm-sun3.h (STACK_END_ADDR): Use system include
4828 files to determine stack end address.
4830 * valarith.c (value_x_binop, value_x_unop): Change error message
4831 to be more useful. Pass proper argument to value_struct_elt.
4833 * valops.c (value_assign): FIXME comment that long long
4834 bitfields will break here.
4836 * Makefile.dist: Add symfile.h, remote-nindy.c, remote-eb.c.
4837 Update `make saber_gdb' to work better.
4839 * TODO: A woman's work is never done.
4841 * cplus-dem.c, environ.c, inferior.h, infrun.c, inftarg.c,
4842 main.c, obstack.c, printcmd.c, remote-eb.c, remote-nindy.c,
4843 remote-vx.c, remote.c, solib.c, source.c, sparc-pinsn.c,

4845 target.c, terminal.h, tm-sparc.h, tm-sunos.h, utils.c,
4846 valops.c, valprint.c, exec.c: Lint.
4849 Wed Dec 12 23:44:15 1990 John Gilmore (gnu at cygnus.com)
4851 Continuing Intel 960 port merge of GDB.
4853 * Makefile.dist: Merge i960 "nindy-share" files. Rename
4854 malloc.h to gmalloc.h to avoid name conflicts in /usr/include.
4855 Don't ship gdb.dvi in tar file. Link gdb with init.o, not init.c.
4856 Wack over "make depend" so it handles files in subdirectories
4857 vx-share, nindy-share, bfd, and in the current directory.
4859 * blockframe.c (get_prev_frame_info): Remove fatal error
4860 if stack not defined.
4862 * core.c (core_open, core_detach): New functions that handle
4863 the old "core-file" command as "target core" and "detach" instead.
4864 (core_file_command): Call them.
4865 (core_xfer_memory): Use common routine xfer_memory.
4867 * dbxread.c: Include a.out.gnu.h, not system a.out.h.
4868 dbxread now uses bfd for everything but symbol reading itself.
4869 BFD internals are used to drag out the relevant file offsets.
4870 (partial_symbol_file_open): Change args all around for BFD.
4872 * symtab.c: Rename "value" to "val" everywhere, so we can
4874 (symbol_file_command): New command, moved from dbxread.c
4875 and coffread.c. It uses BFD to read the file, then vectors
4876 based on its type, to dbx or coff symbol readers.
4877 * symtab.h: Extern a few vars for symbol_file_command.
4879 * target.h: Breakpoint takes a char * save area, not a char **.
4881 * valprint.c (val_print): When unpacking bitfields, offset
4882 the address in gdb of the value, if it is declared with a shorter
4883 type. Remove the last "runtime kludge test" of host byte order.
4885 * utils.c: Remove old my_bfd_read routine.
4887 * stack.c (frame_info): Use target_has_stack. Print program counter
4888 register's actual name rather than "pc", since it's called the
4889 "ip" (instruction pointer) on the i960 (sigh).
4891 * target.c (target_command): Add command for selecting a target
4892 type and calling its open routine. This is used for initiating
4893 communication with a particular target, in a generic way.
4895 * tm-i960.h: Update for modern gdb. Remove semicolons from
4896 various macros. Handle reading struct return convention, and
4897 error-out attempts to return structs with the "return" command.
4898 Be sure gdb doesn't think we know how to call functions in the
4901 * i960-tdep.c: Rename FRAME_CHAIN_VALID and FRAME_FIND_SAVED_REGS
4902 to i960_xxx in lower case.
4903 (arg_address): Circumvent errors due to LOC_ARG_BLOCK
4904 not being defined yet.
4906 * remote.c (remote_open): Call start_remote to initialize
4907 wait_for_inferior during open.
4908 (remote_xfer_inferior_memory): Return length written rather
4911 * remote-vx.c (target_command -> vx_open): Use new generic
4913 * remote-eb.c, inftarg.c, exec.c: ditto.
4915 * infrun.c: Fix comments.
4916 (attach_program -> child_open): Use new generic target command.
4917 (wait_for_inferior): Clear saved register values before target_wait,
4918 so target_wait can set some of them if convenient.
4920 * infptrace.c (fetch_inferior_registers, store_inferior_registers):
4921 Return success indicator, not void.
4922 (child_xfer_memory): Avoid fetching initial word if we'll
4923 overwrite it anyway.
4925 * infcmd.c (attach_command): Use new generic target open routine.
4926 (_initialize_infcmd): Update doc on attach and detach commands.
4927 (do_registers_info): Merge in a byte-order problem as a FIXME
4930 * findvar.c (find_saved_register): Avoid problem in current frame.
4931 (read_relative_register): Ditto.
4932 (write_register): Convert byte order on the way out.
4934 * exec.c (file_command): Add.
4935 (add_to_section_table, exec_command): Use new bfd_map_over_sections.
4936 (xfer_memory): Common function between core_xfer_memory and
4938 (exec_xfer_memory): Use it.
4940 * pn-opcode.h: Document that a "PN" is a Gould PowerNode.
4942 * breakpoint.c, breakpoint.h, symtab.h, value.h, frame.h, utils.c,
4943 valops.c, stack.c, target.c, sparc-xdep.c, source.c, printcmd.c,
4944 infcmd.c, i960-pinsn.c, eval.c, defs.h: lint and gcc -Wall.
4946 Sun Dec 2 16:45:06 1990 John Gilmore (gnu at cygnus.com)
4948 Merge Intel 960 port of gdb, continuing...
4950 * dbxread.c (partial_symbol_file_open, partial_symbol_file_read,
4951 symbol_file_command): Pass from_tty arg to hush 'em up.
4953 * coffread.c (symbol_file_command): Avoid output if from_tty != 1.
4954 Add magic numbers for 960 COFF format.
4956 Fri Nov 30 09:18:20 1990 John Gilmore (gnu at cygnus.com)
4958 Merge Intel 960 port of gdb, from Intel "1.2" release.
4960 CHANGE_LOG entries from their port, which was based on

4964 Remove temp file if download is interrupted.
4966 Wed Aug 1 09:08:33 PDT 1990
4967 Now uses binary protocol to talk to NINDY.
4968 Old hex protocol (NINDY 2.13 and older) supported with -O switch.
4969 Times out after 5 seconds when trying to talk to NINDY.
4971 Tue May 29 12:54:49 PDT 1990
4972 Added variable baud rate (-b switch).
4973 Source code reorganization.
4975 Thu Apr 26 11:09:55 PDT 1990
4976 More cleanup of batch mode; specifically, execute "-s", "-e", and
4977 "-se" switches as soon as they are encountered on the invocation line.
4979 Fri Apr 20 13:47:15 PDT 1990
4982 Thu Apr 19 09:54:28 PDT 1990
4983 Add 'reset' command.
4985 Wed Apr 18 09:48:07 PDT 1990
4986 After opening remote tty, wait for 1 second to go by without input
4987 from it before trying to talk to NINDY (fixes problems with the
4988 Heurikon HK80/V960E).
4990 Mon Apr 4 16:33:05 PDT 1990
4991 Some output was not being suppressed in 'batch' mode.
4993 Thu Mar 22 15:31:11 PST 1990
4994 Ask user if old symbol table should be deleted when new file is
4997 Allow user to run a program downloaded before gdb960 was brought up.
4999 Correct "exec-file" help message for i80960 context.
5001 Correct bug in calculating user space address: could occasionally
5002 corrupt user program.
5004 Make sure to zero low-order bits in rip's because of bug in 960CA
5005 A-step part: could cause operation faults when "next"ing across
5008 Correct bug that made it impossible to get source line numbers for
5009 code loaded at addresses higher than 0x7fffffff.
5011 Wed Jan 10 12:43:22 PST 1990
5012 Open remote tty for exclusive use.
5014 Fri Jan 5 12:14:42 PST 1990
5015 Correct disassembly (CA manual was right after all):
5016 opcode for sysctl is 0x659
5018 Mon Oct 23 12:03:04 PDT 1989
5019 Use G960BASE and G960BIN environment variables to find 'sx' utility.
5021 Mon Oct 16 14:15:09 PDT 1989
5022 "sfr0"-"sfr31" should have been named "sf0"-"sf31"
5024 Mon Oct 2 15:56:31 PDT 1989
5026 Added 960CA disassembly support.
5028 To simplify maintenance:
5029 - eliminated use of symblic links on pinsn.c: use i960-pinsn.c
5031 - eliminated opcode.h: incorporates tables into i960-pinsn.c
5032 - moved 960-specific routines from i960-pinsn.c to i960-md.c
5033 - made disassembly interface identical to that in gdmp960.
5037 Wed Nov 28 21:32:48 1990 John Gilmore (gnu at cygint)
5039 * target.h: Allow targets to stack. Add target_has_memory,
5040 _registers, etc. Restructure memory access and "info files"
5041 to walk the target stack.
5042 * exec.c, core.c, inftarg.c, remote.c, remote-vx.c, remote-eb.c,
5043 target.c: Change tables to match target.h.
5044 * inflow.c (child_mourn_inferior): pop child_ops.
5045 (generic_mourn_inferior): Use new has_stack flag.
5046 * infptrace.c (child_xfer_memory): New memory regime.
5047 * inftarg.c (child_files_info): New "info files" regime.
5048 * remote-eb.c: New memory regime, new info files.
5049 * remote-vx.c: New memory regime, new info files. Now use
5050 separate targets for VxWorks attachment to machine, and
5051 actually running a process under VxWorks, since one has
5052 stack & execution & regs and the other doesn't.
5053 * remote.c: New memory regime, new info files.
5054 * sparc-xdep.c (fetch_core-registers): New memory regime.
5055 * target.c: New routines and support for stacked targets,
5056 new memory regime, new info files regime.
5059 Generalize section handling for an arbitrary number of sections,
5060 including use of the new BFD (binary file) library.
5061 * gdbcore.h: Add struct section_table.
5062 * exec.c (build_section_table): Iterate all sections and
5063 record what gdb needs to know about them.
5064 (exec_command): Use it.
5065 (exec_xfer_memory): Use the table.
5066 (exec_files_info): Print the table.
5067 * core.c (core_file_command, core_xfer_memory, core_files_info):
5069 * source.c (find_source_lines): Use bfd_get_mtime.
5070 * dbxread.c: Quick changes to make it compile with new BFD.
5071 * utils.c (error): Avoid using bfd_error in generic routines.
5073 * core.c (core_fetch_registers): Get from the ".regs" section of
5075 * sparc-xdep.c (fetch_core_registers): Use the .regs info.
5077 * inferior.h (attach_flag): Export.
5078 * infcmd.c (run_command): use new target_create_inferior.
5079 * infrun.c (child_create_inferior): Don't return result.
5080 * Makefile.dist (VERSION): 3.91.4.
5082 Fri Nov 23 28:15:38 1990 John Gilmore (gnu at cygint)
5084 * breakpoint.c (bpstat_num): Handle breakpoints which have
5085 since been deleted, such as temporary breakpoints.
5086 infcmd.c (program_info): ditto.
5088 * core.c (core_file_command): Display the frame where the core
5093 * remote-vx.c (target_command): Merge in target command from
5094 targ-vx.c. A few other cleanups.
5096 * TODO, Projects: Lots more stuff to do...
5098 Fri Nov 23 18:15:38 1990 John Gilmore (gnu at cygint)
5100 Massive changes to wall off the remote-debugging interface
5101 behind a function vector. The port to handle VxWorks targets
5102 is also part of this.
5104 All files: Replace references to renamed functions,
5105 remove references to remote_debugging, remove references to
5106 have_include_file, have_core_file in favor of target_has_stack,
5107 target_has_memory, etc.
5109 * Modularize the breakpoint interface.
5110 breakpoint.h (BREAKPOINT_MAX): New define sets max length of
5111 a breakpoint instruction.
5112 breakpoint.c: struct breakpoint's shadow_contents now sized as
5114 (insert_breakpoints): Vector to target to install breakpoints.
5115 (remove_breakpoints): Vector to target here too.
5116 Remove REMOTE_SA_SPARC kludges and other remote_debugging.
5117 sparc-tdep.c (single_step): Use new breakpoint interface for
5118 the single-step breakpoints.
5119 mem-break.c (memory_insert_breakpoint, memory_remove_breakpoint):
5120 New file, contains routines to insert and remove breakpoints by
5121 reading out the old contents and later replacing them. This is
5122 how ptrace breakpoints work, and many remote systems as well.
5124 * tm-vxworks68.h: New config file, overrides a few things for
5125 Wind River's preferences.
5127 * target.h: New file, for transfer vector used to talk to the
5128 inferior (child, attached, core, exec, remote, etc). All accesses
5129 to the thing being debugged should come through these vectors.
5130 target.c: New file, routines to handle transfer vector.
5131 (various files): Add transfer vectors XXX_ops for the various
5132 targets and pseudo-targets (core files, etc) we support.
5134 * breakpoint.c (bpstat_stop_status): Further explorations of
5135 watchpoints and why things don't work all the time.
5136 (bpstat_alloc): New fn to allocate a bpstat and chain it.
5138 * config.gdb: Only add "source ${srcdir}/.gdbinit" to
5139 the local gdbinit if it doesn't already have it.
5141 * core.c (core_ops): add and install.
5142 Allow core debugging without exec file.
5144 * dbxread.c (free_and_init_header_files): Merge two fns.
5145 (end_symtab): Free named symbol table when a new version comes in.
5146 (read_dbx_symtab): Relocate all kinds of symbols with base
5147 address. First step toward handling different text, data, bss
5149 (add_file_addr_command): Renamed add_file_command.
5150 (add_file_command): Vector to remote handler.
5151 Add "load" as an alias for "add-file" command.
5153 * defs.h: Allow "volatile" to be used in non-ANSI; use it for
5154 non-returning functions.
5156 * exec.c: Add exec_ops, and push it as a target when an exec
5159 * infcmd.c (run_command): Pass executable file name and arg list
5160 separately when starting an inferior. Permit "run" when no exec
5161 file is specified, for VxWorks.
5162 (detach_command): Move to child_detach in inftarg.c.
5164 * inftarg.c: New file. Unix-child-specific routines, and the
5165 child_ops structure.
5167 * inferior.h (registers): Export "registers" as the way for
5168 target dependent register handlers to find gdb's local copy of
5169 the registers. Rename "stop_after_attach" to "stop_soon_quietly"
5170 since it is now used by places that want wait_for_inferior to
5171 handle the grunge but want to see every trap from the inferior.
5173 * inflow.c (create_inferior): Pull out, and merge into infrun.c.
5174 Eliminate remote_debugging hooks in terminal handling.
5176 * infrun.c: Replace start_inferior with child_create_inferior.
5177 Move all the hair of Unix shells and ptrace idiosyncracies into
5178 child_create_inferior, so remote handlers don't have to deal.
5179 Remove running_in_shell. Rename stop_after_attach to
5180 stop_soon_quietly, and use it in a few other places where we want
5181 to just call wait_for_inferior and get control back on the first
5182 trap. trap_expected now never takes a value > 1.
5183 (init_wait_for_inferior): Initialize static vars when a new
5186 main.c (gdbinit): Add new hook for .gdbinit file name, let
5187 it be overridden by config files as GDBINIT_FILENAME.
5188 (DEFAULT_PROMPT): Add new hook for overriding (gdb) prompt.
5189 Both of these are used for VxWorks gdb.
5191 mcheck.c: rename include file "gmalloc.c" to avoid problems
5192 with system include file "malloc.c".
5194 param-no-tm.h: New include file, same as param.h but does not
5195 include the default "tm.h" file. This is used in files where
5196 the target is known, e.g. remote-eb.c or sparc-xdep.c.
5198 param.h: Now just a shell that includes tm.h and param-no-tm.h.
5200 remote-vx.c: New file, VxWorks remote debugging support. Uses
5201 RPC routines that are shared with the target system, in directory
5204 remote.c: Vectorize remote interface.
5206 source.c: Globalize source_path, and make an alias "l" for "list"
5207 since we now have the "load" command.
5209 sparc-xdep.c: Use new param-no-tm.h.
5211 symmisc.c (free_named_symtab): Add new function from Wind River.
5212 However, ifdef it out for now while we think about what it should
5215 tm-sun3.h, xm-sparc.h, xm-sun3.h, xm-symmetry.h: Move
5217 the xm- file, and change its name to CHILD_PREPARE_TO_STORE, since
5218 non-Unix-children handle this with their own code in the target
5221 Makefile.dist: Roll version to 3.92.3. Add vx-share stuff to
5222 source and target lists. Add vx-share to default list of include
5223 directories. Add new files to src and target lists: mem-break,
5224 target, inftarg, remote-eb, remote-vx, targ-vx. Be sure the
5225 ${srcdir} versions of munch and createtags are used.
5227 * valops.c (find_function_addr): Split out of call_function.
5228 (call_function_by_hand): Rename call_function; this function
5229 calls functions in the target by laboriously patching the target
5230 word-by-word with the right stack, args, regs, etc.
5233 Mon Nov 5 17:29:10 1990 John Gilmore (gnu at cygint)
5235 Handle AMD 29000 a bit better.
5237 * remote-eb.c (readchar): Mask received char log to make it readable.
5238 (remote_start): Pass arguments down to executing program.
5239 Make startaddr unsigned.
5240 infrun.c (start_inferior): Accept args, pass them to
5242 infcmd.c (run_command): Pass args down to start_inferior.
5244 * tconfig/am29k-aout, tconfig/am29k-coff: New files specifying
5245 the target object file format.
5246 tm-29k.h: Pay heed to COFF_ENCAPSULATE.
5248 * am29k-pinsn.c (print_insn): Print 0x on hex numbers in disassembly.
5249 am29k-tdep.c (examine_prologue): Better checking of function prefixes.
5251 Sun Oct 7 18:20:45 1990 John Gilmore (gnu at cygint)
5253 * Makefile.dist (VERSION): Roll version to 3.91.9 and freeze.
5254 * TODO: We did a few things, we have more to do though.
5256 * xm-sparc.h (CLEAR_DEFERRED_STORES): Define.
5257 * inflow.c (inferior_died): Clear deferred stores.
5259 * Debug problems with dummy frames and calls to the inferior.
5260 * tm-sparc.h (PUSH_DUMMY_FRAME, POP_FRAME): Move to sparc-tdep.c.
5261 * sparc-tdep.c (do_restore_insn): Simplify.
5262 (sparc_frame_find_saved_regs): Simplify and fix what we find.
5263 (sparc_push_dummy_frame): Simplify and fix what we push.
5264 (sparc_pop_frame): Slightly more hair here, deciding whether
5265 we are restoring a saved PC or returning to a return address in %i7.
5266 * sparc-xdep.c (read_inferior_registers): Debug if valid reg is read.
5268 * utils.c (xmalloc, xrealloc): Return type depends on __STDC__.
5269 * symtab.h (xmalloc): ditto, for obstack_chunk_alloc.
5270 * obstack.h (chunkfun): ditto.
5271 * defs.h (xmalloc, xrealloc): ditto
5273 * utils.c (quit): Grab the terminal from the child if necessary.
5275 * inflow.c (term_status_command): Rename to term_info, change
5278 * sparc-pinsn.c (print_insn): Disassembly prefers real instructions.
5279 (is_delayed_branch): Speed up.
5280 * sparc-opcode.h: Add ALIAS bit to aliases. Fix up opcode tables.
5281 Still missing some float ops, and needs testing.
5283 * Support for input and output radixes other than base 10
5284 * defs.h (input_radix, output_radix): Declare.
5285 * expread.y (yyparse, parse_number): Handle changes of input
5286 radix, and ambiguous names-or-numbers in radixes >10.
5287 * printcmd.c (print_scalar_formatted): Print formatted hex
5288 numbers in varying column widths.
5289 * valprint.c (val_print): Use output_format to print scalar ints.
5290 (set_input_radix, set_output_radix, set_radix): Create.
5291 (set_output_radix): Set output_format from output_radix.
5292 (_initialize_valprint): add `set radix' but leave the others off.
5294 * main.c (execute_command): Let stupid questions be turned off.
5295 (_initialize_main): Handle "set stupidity", etc.
5297 * main.c, inflow.c, inferior.h, frame.h, command.c, defs.h,
5298 sparc-pinsn.c, sparc-xdep.c, value.h, valops.c, values.c: Lint.
5300 Tue Oct 2 11:20:02 1990 John Gilmore (gnu at cygint)
5302 * TODO, Makefile.dist, ChangeLog: Freeze for 3.91.8 release.
5303 bfd stuff is still screwed up, but with some manual work, it
5306 * breakpoint.c (bpstat_do_actions): Start over if a command
5307 proceeds the inferior, since the inferior will have stopped and
5308 will need to have its new stop-actions taken care of.
5310 * dbxread.c (read_struct_type): Expression gives Sun3 4.0.3
5311 compiler fits, simplify it.
5313 * gdb.texinfo (directory command): Doc new dir command.
5314 source.c (directory_command): "dir" now puts things on the front
5315 of the path, moves dups up front, and handles multiple names
5316 on the command line, inserting each one in order. It also
5317 blows away cached line and full_filename info.
5319 * stack.c (backtrace_command): Skip "more stack frames follow"
5322 * Change #ifndef HAVE_VPRINTF to #define MISSING_VPRINTF in
5323 xm-convex.h, xm-hp300bsd.h, xm-isi.h, xm-merlin.h, xm-news.h,
5324 xm-np1.h, xm-pn.h, xm-pyr.h, xm-symmetry.h, xm-umax.h, xm-vax.h.
5325 The only odd one was Gould NP1, which had defined vprintf to
5328 * Merge Ted Goldstein <tedg@Eng.sun.com>'s changes for epoch.
5329 printcmd.c (print_command_1): Pass 'inspect' flag down as a global
5330 variable, inspect_it.
5331 valprint.c (print_string, val_print): Use the global inspect_it
5332 to indicate whether to print in Epoch style or normal style.
5334 Mon Oct 1 23:55:26 1990 John Gilmore (gnu at cygint)
5336 * printcmd.c (call_command): add an alias for the "print" command
5337 which runs expressions and doesn't print the result if void.
5338 (print_command_1): implement it.
5340 * command.c: Remove #if 0'd code. Initialize all the fields
5341 in add_cmd (). Rename do_nothing_command to
5342 not_just_help_class_command, and make it externally visible.
5343 command.h: add user_commands to struct.
5344 * main.c (define_command): Don't overload c->function with a char
5345 string as well as a function pointer.
5347 * eval.c (evaluate_subexp): Reinstall tiemann changes to
5348 calling convention of value_struct_elt () that got dropped in
5351 * tm-sparc.h (FRAME_FIND_SAVED_REGS): move to sparc-xdep.c.
5352 sparc-tdep.c (sparc_frame_find_saved_regs): ditto.
5354 * tm-sparc.h (POP_FRAME): replace some constants with defines.
5356 * sparc-xdep.c (store_inferior_registers): defer stores to regs
5357 until a good time (e.g. when we are about to run the child),
5358 saving ptrace calls.
5359 * infrun.c (proceed): handle DO_DEFERRED_STORES.
5360 * tm-sparc.h: define DO_DEFERRED_STORES.
5362 * sparc-xdep.c (store_inferior_registers): when storing float
5363 registers, don't store stack regs too. When storing the SP,
5364 however, DO store the stack regs too. This fixes a bug in which
5365 the dummy frame is not recognized when a call_function finishes,
5366 because its frame pointer (in the stack regs) was never
5368 (read_inferior_registers): Mark WIM and TBR and FPS and CPS valid
5369 even though we don't know how to read them from an inferior.
5370 valops.c (call_function): Comment about storing SP.
5372 * infrun.c (save_inferior_status): Save away the original bpstat
5373 chain so it can be restored later. Install the copied version for
5374 use by whoever saved the status. It will be blow away by
5375 restore_inferior_status, and the original chain restored. This is
5376 important for people who have pointers into the original.
5378 * breakpoint.c, command.h, copying.awk, dbxread.c, defs.h,
5379 findvar.c, frame.h, obstack.h, obstack.c, inflow.c, value.h,
5380 main.c, printcmd.c, sparc-tdep.c, symtab.c, valprint.c: lint
5383 Fri Sep 28 20:32:46 1990 John Gilmore (gnu at cygnus.com)
5385 * Makefile.dist: Roll version to 3.91.8. Add bfd.h and bfdconfig.h
5386 temporarily to the makefile. Add am29k-opcode.h and WHATS.NEW.
5387 Add stuff.c and kdb-start.c to the OTHERS list for tar files.
5389 Fri Sep 28 19:12:12 1990 John Gilmore (gnu at cygint)
5391 * Merge Mike Tiemann's multiple inheritance changes from Sun.
5392 Store the baseclasses in a type struct starting from array element
5393 0 rather than from the unusual array element 1.
5395 dbxread.c: the above.
5396 (virtual_context): Add
5397 Read new debug information about which virtual function table
5398 a virtual function is from, and store it in fn_field.fcontext.
5400 symtab.h: Add fcontextt. Fix baseclass indices. Typo in
5401 TYPE_FN_FIELD_STATIC_P.
5403 symtab.c: the above.
5404 valops.c: the above. Handle pointer casts of object *'s.
5405 (search_struct_method): Add.
5406 (value_struct_elt): First arg is now a pointer to a value, and is
5409 valprint.c: the above.
5410 values.c (value_virtual_fn_field): Add type arg. Handle
5411 offsetting to the proper object when calling virtual fns.
5413 (baseclass_addr): Add valuep arg.
5415 * README: Document the current state of BFD config (missing).
5416 * TODO, ChangeLog, Makefile.dist: Roll version.
5417 * WHATS.NEW: Add summary of changes since 3.5.
5419 Thu Sep 27 16:23:12 1990 John Gilmore (gnu at cygint)
5421 * dbxread.c (read_struct_type): Clear bit vectors whenever
5423 symtab.c (B_CLRALL): define.
5425 * tm-sparc.h (STORE_RETURN_VALUE): Avoid clobbering types by
5426 using == rather than =. Huh... This fixes the dreaded problem
5427 wherein builtin_type_int becomes TYPE_CODE_FLT.
5429 * core.c (info_files): Show the inferior pid.
5431 * config.gdb: Avoid putting "dir" command into .gdbinit. GDB
5432 already knows how to look in the source directory.
5434 * Remove psymtab hair from many places. Remove duplicated code
5435 for searching symbol tables. Hide psymtabs from most places.
5436 Make it fast to get from a psymtab to its symtab.
5438 blockframe.c (blockvector_for_pc): Remove psymtab hair.
5439 coffread.c (psymtab_to_symtab): Rename to psymtab_to_symtab2.
5440 mipsread.c (psymtab_to_symtab): Rename to psymtab_to_symtab2.
5441 dbxread.c: export psymtab_to_symtab, make it work if called N times.
5442 (psymtab_to_symtab): Rename to psymtab_to_symtab2. Initialize
5443 new symtab completely. New psymtabs get symtab pointer
5444 initialized to zero. Remove MI warning printf.
5445 symtab.h: Comments. Add psymtab to symtab pointer.
5446 (PSYMTAB_TO_SYMTAB): New macro.
5447 symtab.c: use PSYMTAB_TO_SYMTAB. Add psymtab_to_symtab and export it.
5448 source.c: use PSYMTAB_TO_SYMTAB. Remove symtab version and
5450 stack.c (backtrace_command): Avoid pre-pass to read symbols, if
5452 (print_frame_info): Avoid special-casing symbols that have not yet
5455 * source.c (open_source_file): Quick path if we have already
5456 located the source file by its full name.
5458 * symtab.c (lookup_symbol): Use find_pc_symtab rather than
5459 find_pc_psymtab. When a name is found in the misc function
5460 vector, search the symbol table for its mangled name, not the
5461 name that the user typed.
5463 * bfd.h: Fix missing comment terminators, make #endifs match.
5465 * valarith.c (value_less): Handle unsigned int comparisons.
5466 Add FIXME about pointer compares, which assume host and target
5467 pointers are the same.
5469 * command.c (do_nothing_command): lint
5470 dbxread.c: lint. Remove sort_syms. Document C++ visibility info,
5471 fix comments on debug symbol format for visibility. Actually set
5472 visibility of symbols.
5473 main.c (echo_command): lint; use <readline/history.h>.
5474 tm-sparc.h (FRAME_FIND_SAVED_REGS): lint
5475 obstack.h (_obstack_blank): Rearrange pointer math to avoid
5476 pointing past end of allocated memory; saber complains.
5477 obstack.h: Declare the external functions that we use.
5478 valarith.h: use <string.h>
5479 solib.c (solib_add): lint.
5481 Fri Sep 21 17:05:19 1990 John Gilmore (gnu at cygint)
5483 * main.c (initialize_main): Default info_verbose to off, now that
5484 symbol reading is fast.
5485 (quit_command): Avoid clobbering exec_bfd while quitting.
5487 * Initial BFD (binary file diddling library) merger:
5488 coffread.c: Change AOUTHDR to struct exe_hdr.
5490 core.c: initialize initialized data at compile time.
5491 (core_file_command): Move from coredep.c, convert to bfd.
5492 (xfer_core_file): Convert to bfd.
5493 exec.c (exec_file_command): use bfd routines.
5495 mips-tdep.c: Remove exec_file_command and friends.
5498 * coredep.c: (fetch_core_registers) Convert core_file_command to
5499 fetch_core_registers.
5500 mips-xdep.c, sparc-xdep.c, sun3-xdep.c: ditto.
5502 * utils.c: (error): Bogus crap, FIXME, to print bfd errors.
5503 (my_bfd_read): More bogosity, which I don't think we call.
5504 (program_name): Remove this atrocity asap!
5506 Wed Sep 19 13:36:41 1990 John Gilmore (gnu at cygint)
5509 values.c: allocate_repeat_value was not clearing the
5510 optimized_out field.
5511 (value_static_field): minor stylistic fix (wrong macro was used).
5512 valops.c (value_struct_elt_for_address): didn't work for C++
5515 * signame.c (_initialize_signame): Initialize signal names once.
5517 * breakpoint.h, command.c, copying.awk, defs.h, environ.c,
5518 exec.c, frame.h, infcmd.c, inferior.h, main.c, munch, sun3-xdep.c,
5519 symtab.h, tm-29k.h, valprint.c, value.h, values.c: Lint.
5521 * remote-eb.c: Support user-settable baud rates on the serial port.
5523 * tm-sun3.h (PREPARE_TO_STORE): fix typo.
5525 Fri Sep 14 13:28:29 1990 John Gilmore (gnu at cygint)
5527 * tconfig/sun3os4: Remove warning about native assembler,
5528 since it also occurs in the xconfig file.
5530 * findvar.c (registers): Allocate some slop after `registers'
5531 to prevent stray accesses from trashing the next variable.
5533 * tm-68k.h (REGISTER_BYTES): Allocate the right number of bytes
5534 on the sun-3, by changing the #ifdef from `sun3' (which is not
5535 defined by cc) to `sun'. Symptom was trashed builtin_type_XXX
5536 vars, which happened to follow `registers' in the executable.
5538 * readline/history.c (history_search): Heed gcc-2's advice
5539 and parenthesize && inside ||).
5541 * am29k-opcode.h, am29k-pinsn.c, am29k-tdep.c, remote-eb.c,
5542 tm-29k.c: Insert FSF copyright headers.
5544 * remote-eb.c: Better comments.
5546 * Makefile.dist: Update to 3.91.6.
5547 * TODO: note PREPARE_TO_STORE problem.
5549 Thu Sep 13 09:52:33 1990 Jim Kingdon (kingdon at cygint)
5551 * stack.c (frame_info): Only use FRAME_FIND_SAVED_REGS if defined.
5553 * remote.c: Wrap the whole file in #if !defined (SPECIAL_REMOTE).
5555 * infrun.c (wait_for_inferior, at end): Don't set up
5556 prev_* if the inferior no longer exists.
5558 * inferior.h (CALL_DUMMY_LOCATION): New macro, to replace
5559 CANNOT_EXECUTE_STACK.
5560 valops.c (call_function): Use it.
5562 * tm-convex.h: Add CALL_DUMMY_LENGTH for use by PC_IN_CALL_DUMMY.
5564 * inferior.h (PC_IN_CALL_DUMMY): New macro.
5565 infrun.c (wait_for_inferior, 2 places): Use it.
5567 * values.c (value_being_returned): Only use
5568 EXTRACT_STRUCT_VALUE_ADDRESS if defined.
5570 * Move PREPARE_TO_STORE from xm-sun3.h to tm-sun3.h to do the
5571 right thing for remote-eb.c.
5573 * sun3-xdep.c: Remove extraneous call to remote_store_registers.
5574 * sun386-xdep.c, hp300hpux-xdep.c, sparc-xdep.c: Ditto.
5576 * blockframe.c: Put get_frame_saved_regs inside #if !defined
5577 (FRAME_FIND_SAVED_REGS).
5579 * findvar.c ({fetch,store}_registers): Check for
5580 REMOTE_{FETCH_STORE}_REGISTER macro.
5582 * findvar.c (get_saved_register): Add argument lval and
5583 change meaning of argument addr.
5584 findvar.c: Change calls to get_saved_register to reflect
5585 new calling convention.
5586 valops.c (value_assign): Use get_saved_register instead of
5587 find_saved_register.
5589 Sun Sep 2 12:40:20 1990 Jim Kingdon (kingdon at cygint.cygnus.com)
5591 * coffread.c (read_one_sym): Make temp_aux an AUXENT, not
5592 an (uninitialized) pointer to one. Use "&" when passing it
5595 Fri Aug 31 22:57:54 1990 Jim Kingdon (kingdon at cygint.cygnus.com)
5597 * coffread.c (getfilename): Use DGUX x_offset and x_name if
5600 * coffread.c (symbol_file_command): Put semicolon after
5602 Put safe_to_init_tdesc_context in #if defined (TDESC).
5603 Put #ifdef TDESCs in 1st column for non-ANSI cpp's.
5604 coffread.c: #include <sys/stat.h>.
5605 (read_coff_symtab): Typo: in_source_files -> in_source_file.
5606 Add missing ')' in check for "lc%" and friends. Remove
5608 Declare read_one_sym() at top of file.
5609 (read_file_hdr): Put in extra #ifdefs so MC68MAGIC and
5610 MC68WRMAGIC can have the same value without causing a duplicate
5613 Thu Sep 13 15:55:36 1990 John Gilmore (gnu at cygint)
5615 * Allow a Makefile to be built without building the
5616 tm and xm file links that screw up builds in subdirectories.
5617 This is done with `config.gdb none', then you can do things
5618 like `make gdb.tar.Z'.
5619 * tconfig/none: Config file for no target system
5620 * xconfig/none: Config file for no host system
5621 * config.gdb: If no TM or XM files are called out by the
5622 host or target file, don't make links for them.
5624 * cplus-dem.c: Add documentation.
5626 * dbxread.c (read_ofile_symtab): Turn a fatal error into a
5627 simple error, so the user's gdb doesn't crash due to some object
5628 file problem (e.g. somebody is rebuilding the file out from under
5631 * printcmd.c (print_address_symbolic): demangle the symbol.
5633 * Makefile.dist (OTHERS): Remove tdesc-lib because it has
5634 Motorola copyrights in it. Make "make gdb.tar.Z" work.
5635 (alldeps.mak): sort and uniq all results from this; duplicates
5636 hose gdb.tar.Z link building. Remove RCS files from
5637 tconfig and xconfig. Add config files for sun386. Add
5638 a few odd files to OTHERS and HFILES.
5640 Mon Sep 10 21:20:24 1990 John Gilmore (gnu at cygint)
5642 * Makefile.dist: Pull solib.c to tconfig/sun?os4.
5643 Roll version number to 3.91.5. Make lint work in bindir.
5645 * README: Document cross-debugging and new file structure.
5647 * blockframe.c: Lint. Include "value.h" to declare read_register.
5648 (find_pc_partial_function): remove duplicate line.
5650 * command.h: Lint. Declare error_no_arg and dont_repeat.
5652 * tm-news.h: Remove inadvertently duplicated stuff.
5654 * mipsread.c: Remove cache_pc_function stuff, now done cleanly.
5655 Clean up usage of misc_function_type. Declare some CORE_ADDRs.
5657 * config.gdb: Allow `config.gdb host target' form. Clean
5658 up previous change that printed bogus messages when you just said
5661 * core.c: #include "command.h" for lint.
5664 * main.c: Remove some casts of enums. Lint.
5671 * printcmd.c (initialize_printcmd): Fix thinko in inspect cmd.
5673 * sparc-tdep.c (isannulled): Take instruction as parameter, don't
5674 read it from memory. This will allow us to save ptrace calls
5675 eventually. Changed caller single_step too.
5677 * sparc-xdep.c (fetch_inferior_registers): Avoid reading regs
5678 that we aren't going to use, saving many ptrace calls, especially
5679 when watchpointing or single stepping. Use some #define's for
5681 (store_inferior_registers): Ditto.
5682 (core_file_command): Use some #define's for constants.
5684 * tm-sparc.h: Add #define's for some register numbers, so we
5685 can eliminate the use of random constants in sparc-xdep.c.
5687 * stack.c (frame_command, print_frame_info, up_command,
5688 down_command) Remove frame_changed, since it
5689 causes a bug and doesn't seem to do anything useful. In some
5690 places it was used as a flag, in others as a stack level (?).
5692 * utils.c: Use MISSING_VPRINTF rather than HAVE_VPRINTF, so the
5693 default is to use the portable (vprintf) version rather than the
5695 * xm-news.h (MISSING_VPRINTF): Add.
5697 * valprint.c (val_print): Demangle fancy vtbl printouts. Lint.
5699 Sat Sep 8 00:24:12 1990 John Gilmore (gnu at cygint)
5701 * Remove stuff that forces -Bstatic linking of gdb, and warnings
5702 about linking debugged programs -Bstatic in the sun?os4 config
5703 files in tconfig and xconfig subdirectories.
5705 * main.c (main): Remove unreached exit(0) now that we exit
5708 * Create TODO file for online bug list. There are too many
5709 "little" bugs to keep track of on paper.
5711 * Change Projects file to refer to bug-gdb@cygnus.com
5712 rather than kingdon@ai.
5714 Fri Sep 7 23:35:15 1990 John Gilmore (gnu at cygint)
5716 * Makefile.dist (VERSION): 3.91.4 now.
5718 * symtab.c (init_misc_bunches): Rename from init_misc_functions.
5719 (condense_misc_bunches): Add sanity check that misc_count is
5720 the same as the number of symbols in the bunch.
5722 * coffread.c: rename init_misc_bunches. Pass an argument
5723 to condense_misc_bunches (a zero).
5725 * dbxread.c (partial_symbol_file_read): Call init_misc_bunches
5726 every time we are called; don't rely on our caller to do it.
5727 (add_file): Remove call to init_misc_bunches.
5729 * mipsread.c: Only warn, don't error, if unknown symbol types.
5730 This keeps an old gdb from falling on its face if it sees newly
5731 extended symbol info. Rename init_misc_bunches.
5733 Fri Sep 7 22:58:15 1990 John Gilmore (gnu at cygint)
5735 * Merge in changes from Per Bothner for DECstations and other
5736 MIPS stuff. The rest is Bothner speaking:
5738 The next message is a merger of Alessando Forin's mips port with
5739 mine. I've tried to use my good if biased judgment to get
5740 the best of both. It *does* need testing.
5742 Some of the changes are general, *not* mips-specific.
5745 Didn't believe in little-endian bit order.
5746 There are still inconsistencies about whether flags
5747 like BITS_BIG_ENDIAN are integer (#if ...) or
5748 boolean (#ifdef ...). I tried to paper over them.
5750 dbxread.c,coffread.c,mipsread.c,symtab.c,symtab.h:
5751 Moved some misc_function code that was common to
5752 {dbx,coff,mips}read.c to symtab.c.
5753 In the process, I think I cleaned things up a bit.
5754 At the same time, moved obsavestring and obconcat to symtab.c.
5757 Removed obsolete condense_addl_misc_bunches (use
5758 condense_misc_bunches(1) instead).
5761 Needed to include <sys/dir>, at least on DECstations.
5763 valops.c, mips-tdep.c, tm-mips.h:
5764 Added PUSH_ARGUMENTS macro to support funny argument-pushing
5765 conventions (when STACK_ALIGN is insufficient).
5766 Needed on mips, where doubles need 8-byte alignment,
5767 but ints only need 4.
5770 Removed cruft that was not being used.
5771 Merged in many fixes (most from Frank Yellin, fy@lucid.com).
5774 Print $ before register-names (I think that makes things a little
5776 Never print two instructions, even if one delays.
5777 Removed hex-disassemble set_cmd. (This is not mips-specific,
5778 so I think the argument is whether it is generally worthwhile or not.
5779 I'm inclined to think not, given how easy it is to
5780 convert between radixes in gdb.)
5783 This is basically Alessando's code.
5784 It doesn't use obstacks; I changed it to use obstacks
5785 in a few minor places where using malloc causes a
5786 memory leak. (Probably, more places could/should be changed.)
5787 I added record_misc_function where it was missing.
5788 In symbol_file_command and add_file_command, I tried
5789 to make the code consistent with more recent versions.
5790 Minor sylistic changes in parse_procedure.
5791 Make a .gdbinfo. psuedo-symbol point back to the real
5792 procedure symbol (using the isym field).
5795 This is basically from my port, but with a lot of details
5796 and a number of routines merged in from Alessando's version.
5797 I basically used my code "raw" backtrace (use heuristics
5798 from the actual code, rather than symbol table info) - though
5799 the idea is Alessandro's. I feel my code is a little cleaner
5800 here, particularly in being a little more flexible, such as being
5801 able to handle gcc-produced code (which it now can).
5802 It also doesn't do frame caching (which is not useful
5803 more recent gdb versions).
5804 I also used my code for push_/pop_dummy, more or less.
5805 I tried to incorporate AF's code for testing sigtramp
5806 while backtracing; I probably got it wrong.
5807 Added mips_print_register, which tries to scrunch as much
5808 information as possible on a screen...
5809 Removed the skip-prologue set_cmd. As with hex-disassemble (see
5810 under mips-pinsn.c), I don't see anything mips-specific here,
5811 and I don't see it being all that useful anyway.
5814 Added a $fp psuedo-reg distinct from $fp (nice for gcc).
5815 Use more register names (rather than hard-cases numbers).
5817 Thu Sep 6 18:33:15 1990 John Gilmore (gnu at cygint)
5819 * Hack up 3.90.11 changes:
5821 * Makefile.dist (depend): parameterize $(GCC).
5822 Add solib.c and solib.o.
5823 (readline): Fix vpath for both absolute or relative SRCDIR.
5825 * blockframe.c: Fix from Schaefer@asc.slb.com for shared libs.
5826 Also, let the part I didn't understand at least compile so
5827 I can test the rest. FIXME.
5829 * dbxread.c: Fix thinko using strcmp.
5830 (init_psymbol_list): declare static.
5831 (partial_symbol_file_open): Comment cleanups better, avoid
5832 cleaning up the string table since the caller will do that.
5833 Move the stat for mod time into symbol_file_command, temporarily.
5834 (There should be a mod time for each symbol file, eventually,
5835 to control its rereading. FIXME.)
5837 * infptrace.c (PT_WRITE_D): use same value as PT_WRITE_I for
5838 SunOS, which gives error for shared libs otherwise. (From
5839 Schaefer, probably FIXME needs work for portability.)
5841 * solib.c: Move #include "param.h" to work.
5842 Lowercase all the Uppercase Letters In the Messages.
5843 (find_solib): Clean up inferior_so_name for debug printouts.
5844 Allow no argument, to mean all shared libraries.
5846 * symmisc.c: include param.h to get CLEAR_SOLIB.
5848 Wed Sep 5 18:00:08 1990 John Gilmore (gnu at cygint)
5850 * Merge in Kingdon's changes from FSF: the diffs from 3.90.9
5851 to 3.90.11. ChangeLog entries below are from this.
5853 Wed Jun 13 09:17:39 1990 Jim Kingdon (kingdon at mole.ai.mit.edu)

5865 Thu Jun 7 16:22:27 EDT 1990 Jay Fenlason (hack@ai.mit.edu)
5867 * sparc-opcode.h Added single-operand version of rett.
5869 Mon Jun 4 18:12:31 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5871 * m-sparc.h (REG_STRUCT_HAS_ADDR, STRUCT_ARG_SYM_GARBAGE):
5872 Put parens around gcc_p in expansion.
5874 Thu May 24 15:44:51 1990 Jim Kingdon (kingdon at mole.ai.mit.edu)
5876 * utils.c (lines_to_list): Return 10 if lines_per_page == 0.
5878 Wed May 23 16:36:04 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5880 * Changes for Sun shared libraries:
5881 blockframe.c (find_pc_partial_function): If a non-text symbol
5882 is found, set *address = pc - FUNCTION_START_OFFSET.
5883 breakpoint.c (insert_breakpoints) [DISABLE_UNSETTABLE_BREAK]:
5884 Disable breakpoints instead of giving an error.
5885 source.c (select_source_symtab): Initialize cs_pst.
5886 symmisc.c: Call CLEAR_SOLIB if defined.
5887 symtab.h: Make text{low,high} CORE_ADDR not int.
5888 (psymtab): New field addr.
5890 dbxread.c: Move DECLARE_FILE_HEADERS outside functions.
5891 (record_misc_function): Give correct type for N_DATA symbols.
5892 (condense_misc_bunches): do "misc_function_count = j" regardless
5894 Take code which is shared between symbol_file_command and
5895 add_file_command and put it into partial_symbol_file_{open,read}.
5896 Split add_file_command into add_file_command and add_file.
5897 Make psymtab_to_symtab read in the string table if the file
5899 Two new parameters to read_dbx_symtab and start_psymtab.
5900 tm-sunos.h: New file.
5902 Tue May 22 17:43:03 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5904 * infcmd.c: Change cont_command to continue_command and "cont"
5907 Mon May 21 14:41:41 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5909 * breakpoint.c (enable_breakpoint): Get value of watchpoint.
5911 * defs.h [sparc]: Use <alloca.h> regardless of __GNUC__.
5913 * values.c (USE_STRUCT_CONVENTION): Check for structures of
5914 size 1,2,4,8 rather than size < 8.
5916 * dbxread.c (dbx_lookup_type): Do f->length *= 2 as many times
5917 as necessary, not just once.
5919 * sparc-opcode.h: Add a bunch of new opcodes which Sun as supports.
5921 Thu May 17 15:04:09 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5923 * {t,x}m-sun386.h, sun386-xdep.c, {x,t}config/sun386
5925 * tm-news.h: Add CALL_DUMMY_*.
5927 * tm-68k.h: Remove duplicate comment at FRAME_FIND_SAVED_REGS.
5929 * config.gdb: In list_host, list_target, use ${i}, not $i.
5931 Tue May 15 21:27:12 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5933 * source.c (find_source_lines) [BROKEN_LARGE_ALLOCA]: Use xmalloc.
5935 * sparc-opcode.h: Change all store floating-point state register
5936 instructions to have the right match & lose fields.
5938 Sat May 5 12:39:18 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5940 * Makefile.dist: Move -I${srcdir} to GLOBAL_CFLAGS and pass
5942 config.gdb: If srcdir != ., create readline directory and
5943 copy a makefile into it.
5945 * wait.h, infrun.c: Change WRETCODE to WEXITSTATUS for
5946 consistency with POSIX.
5948 * breakpoint.c (bpstat_stop_status): Disable watchpoint
5949 when we exit its exp_valid_block.
5951 Tue Sep 4 11:46:46 1990 John Gilmore (gnu at cygint)
5953 * Makefile.dist: Bump version to 3.91.3.
5955 * Clean up handling of breakpoint commands (somewhat).
5956 Prompted by Tiemann bug report "cont 10" doesn't work any more.
5958 inferior.h: Add breakpoint_proceeded to inferior status struct
5959 and globals; save it and restore it.
5960 (clear_breakpoint_commands): Cleanup, remove old #define.
5962 infrun.c (clear_proceed_status): Set breakpoint_proceeded.
5963 (save_inferior_status, restore_inferior_status): handle it also.
5964 (proceed): Remove earlier code that set breakpoint_proceeded.
5965 It is now set only in clear_proceed_status.
5966 (clear_proceed_status): Cleanup, use bpstat_clear rather
5967 than clear_breakpoint_commands. No callers need the stop_bpstat
5968 between clear_proceed_status and proceed.
5970 infcmd.c: Add breakpoint_proceeded definition and comment.
5971 (cont_command, jump_command, signal_command): Move call to
5972 clear_proceed_status right next to call to proceed.
5974 breakpoint.c (bpstat_do_actions): Avoid clobbering our
5975 caller's argument while running down the chain of breakpoints.
5976 Use new variable "breakpoint_proceeded" to determine when
5977 a command that it executes moves the inferior past the
5979 (bpstat_clear): Handle NULL argument.
5980 (bpstat_clear_actions): Avoid useless call to
5981 breakpoint_auto_delete.
5982 (delete_breakpoint): Clean up bpstat's that are pointing to
5983 the deleted breakpoint from the stop_bpstat chain.
5984 (breakpoint_auto_delete): Simplify.
5986 * Clean up handling of EOF, error on stdin, etc. This was
5987 prompted by a network problem that caused gdb to go into an
5988 infinite loop filling up its malloc'd memory.
5990 main.c (return_to_top_level): Cleanup: call bpstat_clear_actions,
5991 not clear_breakpoints_commands, which is now gone.
5992 (main): If command_loop returns (e.g. from EOF on stdin), do
5993 a quit_command (looping back to command_loop if quit_command
5994 doesn't really quit).
5995 (command_loop): check result from command_line_input and
5996 exit if it returns NULL, rather than passing the NULL to
5998 (gdb_readline): Free malloc'd result space before returning
6001 * utils.c (query): Handle C-d to mean "yes", just as if the
6002 input was not a terminal. Also avoid infinite loop if EOF
6003 occurs in mid-input-line before newline. This allows
6004 query to be used at EOF on stdin with reasonable results.
6006 * infrun.c (proceed): Set breakpoint_proceeded.
6008 * values.c (value_as_long): Avoid infinite recursion for enums.
6009 (_initialize_values): Fix typo in help msg (kingdon).
6011 * Makefile.dist (RL_LIB): Use RL_LIB_DEP for dependencies,
6012 RL_LIB for linking. This allows -lreadline for linking
6013 and nothing for dependencies, once readline is a real library.
6015 * config.gdb: Jim Kingdon: give useful error message if the
6016 host or target type is not recognized.
6018 * defs.h (alloca): SPARC <alloca.h> does not declare alloca,
6019 it just defines it. Dumb, but deal with it.
6021 * Jim Kingdon suggests:
6022 in xconfig/sun3os4, CFLAGS should be XM_CFLAGS.
6024 Wed Aug 29 18:03:27 1990 John Gilmore (gnu at cygint)
6026 * Makefile.dist (VERSION): Bump version # to 3.91.2.
6028 * Clean up Bothner's changes.
6030 * blockframe.c (clear_pc_function_cache): New function.
6031 * blockframe.c: remake cache_pc_function_* static.
6032 * dbxread.c (symbol_file_command): remove references to
6033 cache_pc_function_* variables.
6034 * dbxread.c (read_struct_type): Use VOFFSET_STATIC.
6035 * printcmd.c: Avoid kludging a global variable (addressprint)
6036 to avoid printing the address of a string twice. Instead,
6037 pass the format letter 's' down low enough that it can be seen
6038 to avoid this problem.
6039 (print_formatted): Pass format arg to value_print.
6040 (restore_addressprint): Remove function.
6041 (do_examine): Avoid hacking addressprint, cleanups and such.
6042 (print_frame_args): Add a comment to a Bothner change.
6043 * symtab.h: define VOFFSET_STATIC and use it instead of "-1".
6044 * symmisc.c (free_all_symtabs): Call clear_pc_function_cache
6045 to wipe out the values cached in blockframe.c.
6046 * symtab.c (find_method): Add comment saying how big you must
6047 allocate to be "big enough". Per being terse again.
6048 * valprint.c (val_print): Handle format letter "s" to print
6049 strings without addresses. Add comment to vtbl printing code
6050 which casts with wild abandon. Rearrange reference-printing
6052 @0xaddr: value (print w/addressprint)
6053 value (print w/~addressprint)
6054 @0xaddr (parameter lists w/addressprint)
6055 or nothing (parameter lists w/o addressprint)
6057 Tue Aug 28 10:47:18 1990 John Gilmore (gnu at cygint)
6059 * Merge more changes from Per Bothner:
6061 Gdb's handling of TYPE_CODE_REF was so counter-C++ (and otherwise
6062 annoying) that I tried to improve it. Here are my suggestions.
6064 These patches all attempt to handle TYPE_CODE_REF (as in C++) better.
6067 Do automatic de-reference when taking the address of a reference.
6069 Don't deref_ref when printing parameter lists.
6071 More attempts at treating refernences properly.
6073 In val_print, if deref_ref==0, don't print dangling " = ".
6075 Add COERCE_REF macro, which de-references an REF.
6077 * Merge changes from Per Bothner:
6079 * Fixed (Sony news)-specific configuration problems.
6080 * Fixed other problems with using vanilla pcc and libc (enum problems;
6081 assumption that vsprintf exists).
6082 * Some major speed-ups (finc_pc_partial_function now caches a match;
6083 parsing avoids duplicate symbol_lookup calls).
6084 * Changed handling of baseclasses (no longer use baseclasses field
6085 of struct type, use the first n_baseclasses fields instead).
6086 * Various minor changes/fixes, most C++-related.
6089 Cache the most previous match from find_pc_partial_function.
6090 (Save both low and high ends of matching function's pc range.)
6091 This speeds up the loop of infrun.c:wait_for_inferior quite
6092 a bit, and makes step/next commands much zippier.
6094 Added an enum->int cast (otherwise, some compilers barf).
6096 No longer set baseclass offset to 0, since multiple
6097 inheritance now mostly works.
6098 Added a number of casts, to shut up compiler warnings
6099 (after stabs where made enums, not ints).
6100 When discarding a symbol table (in symbol_file_command),
6101 must clear the cache introduced in blockframe.c.
6102 Don't convert $vtbl_ptr_type to vtbl any more.
6103 Get rid of TYPE_BASECLASEES and baseclass_vec (see also symtab.h).
6104 Mask off sign bit emitted by g++ for virtual table offset.
6105 Set voffset to -1 (not 1) for static member functions.
6107 Changed parsing/lexing of names to avoid doing symbol lookup twice
6108 (once when lexing to determine symbol class, once for real).
6109 Now only call symbol_lookup once. Fields of 'this' win especially big.
6111 Subpress printing addr twice in the case of 'x/s addr'.
6113 lookup_basetype_type is no longer used.
6114 Add find_methods as recursive helper function to decode_line_1.
6115 This allows multiple inheritance to work.
6116 Also, once one or more matches has been found, do not look in
6117 base-classes. (Baseclass methods would be overridden, anyway.)
6119 Removed baseclasses array in struct type.
6120 Instead of using baseclasses[i], use fields[i-1].
6121 Added virtual_field_bits[i] to indicate if the i'th baseclass is virtual.
6122 Changed sign convention of voffset (previous was inconsistent).
6124 Some macros (CALL_DUMMY and relatives) were missing. Put them back.
6126 Used to assume existence of vsprintf. Re-written to not need it
6127 if HAVE_VPRINTF is undefined.
6129 typecmp was too pessimistic. Made it less so.
6131 Don't print space after address.
6132 If vtable points to a misc symbol (with 0 offset), print it,
6133 since that indicates the actual class of the object.
6134 Changed ype_print_derivation_info to use new inheritance
6135 scheme (without baseclasses vector).
6137 In value_primitive_field, fixed some bugs left over from previous set of fixes.
6138 Also, changes needed because TYPE_BASECLASSES were removed.
6140 REGISTER_U_ADDR didn't work for PC. Rewrote to use an array.
6142 Tue Aug 21 20:08:54 1990 John Gilmore (gnu at cygint)
6145 If there is no path set, and the symbols don't indicate what directory
6146 a file was compiled in, look in the current directory. But either
6147 a path or a known compilation directory will prevent this.
6150 Three independent bug fixes:
6151 * Remove the #if 0 block that breaks some stuff.
6152 * SunOS 4.1 fixed the promoted-parameter-wrong-addr bug in Sun C;
6153 adapt gdb to either SunOS 4.0.* or 4.1.
6154 * MAX_OF_TYPE and MIN_OF_TYPE thinko. By tedg@sun, I think.
6157 Instantiate the class T when looking for methods in it. (Tiemann@sun)
6160 (type_print) Demangle the name being printed.
6161 (type_print_base) Handle botched demangling without coredump (tiemann).
6164 (check_stub_method): Document routine.
6165 (tiemann) fix bug for no-arg functions
6166 Avoid clobbering beyond end of malloc'd storage.
6167 Terminate the argument list properly.
6169 Sat Aug 18 01:29:59 1990 Per Bothner (bothner@cs.wisc.edu)
6171 * Changes merged by John Gilmore:
6174 In breakpoint_1, use new print_address_symbolic instead
6175 of find_pc_partial_function. (This forces use of assembler-level
6176 addresses, and avoids misleading non-mangled source-level names.)
6178 Generalize ansi argument such that -1 means skip arglist totally.
6179 Removed global variable print_ansi_qualifiers (which made
6180 code non-reentrant), in favor of extra explicit arguments
6181 to internal routines.
6183 Add new helper function print_address_symbolic.
6184 Use find_pc_misc_function instead of find_pc_partial_function
6185 (since we want assembler-level symbols here).
6187 Print unknown function as just "f (...)", not "f (...) (...)".
6188 Use new fputs_demangled explicitly.
6190 Fixed a typing violation (problem: value.h cannot be imported
6191 without renaming many variable in this file).
6192 lookup_symbol: If no matching misc_func, look for a C++-mangled name.
6193 decode_line_1: Moved forward some never-reached code.
6194 Made decode_line_2 skip function prologues correctly.
6196 fputs_filtered should not demangle by default.
6197 Add new fputs_demangled to demangle on demand..
6199 Change value_struct_elt to use value_primitive_field (using recursive
6200 utility function search_struct_field). This allows foo.bar to work
6201 for multiple inheritance (so far only for data fields).
6202 Change check_field in the same way (recursive helper function
6203 to support multiple inheritance).
6204 (Note: there are more of these problems that I haven't fixed.
6205 Any code that says TYPE_BASECLASS (t, 1) is probably wrong.)
6206 value_of_this: 'this' symbol name is now just "this", note "$this".
6208 Don't print static members.
6209 Avoid printing "members of <type>" if there are none.
6210 Simplified type_print_derivation_info by merging duplicate code.
6211 Remove useless blank lines in type_print_base (ptype command).
6213 Added declaration of new routine value_primitive_field.
6215 Added value_primitive_field which is generalized version of
6216 value_field that can handle multiple inheritance (non-zero offsets etc).
6217 Re-implemented value_field to call value_primitive_field.
6219 Fri Aug 17 23:33:44 1990 John Gilmore (gnu at cygint)
6221 * infcmd.c -- insert else to avoid 'delete env' coredump when you
6222 delete the whole environment. Karl Berry reported the bug.
6223 * source.c - fix openp to avoid //'s in filenames, which
6224 trigger an Emacs bug causing it to not be able to find files
6225 when running gdb in a window.
6226 * dbxread.c - zap the #if 0 that botches the add-file code.
6227 It seems to work a lot better without all the code commented out.
6229 Fri Jul 20 16:58:46 1990 John Gilmore (gnu at cygnus.com)
6231 * Merge Tiemann's and Ted Goldstein's changes, detailed below,
6234 Tue Jul 17 19:34:33 1990 Ted Goldstein (tedg at golem)
6236 * Makefile - added a ${CFLAGS} to a couple of entries,
6237 added remote-sa.sparc.c
6238 * added remote.sa-sparc.c, a modification of remote.c
6239 which conducts a dialog directly with the SparcStation prom.
6240 * breakpoint.c, infrun.c, sparcdep.c added
6241 remote_insert_breakpoint(), and remote_remove_breakpoint()
6242 to breakpoint.c instead of directly writing breakpoint instructions.
6243 * sparcdep.c on remote_debugging,there is no need
6244 to remove signle step breakpoint instructions.
6245 * main.c added "-epoch" flag and "int epoch_interface" to main.c
6247 * printcmd.c - epoch interface sends lisp expressions to open up
6248 epoch windows on inspection.
6249 * valprint.c - added arrayprint, and addressprint and made adding
6250 format controls easier
6251 * wait.h added a couple of undef's because we were getting
6252 complaints about WSTOPSIG and WTERMSIG begin redefined.
6255 Wed Jul 4 05:27:51 1990 Michael Tiemann (tiemann at masham)
6257 * symtab.c (decode_line_1): Add support for handling method stubs
6258 in the type information.
6260 Tue Jul 3 09:39:18 1990 Michael Tiemann (tiemann at masham)
6262 * values.c (baseclass_addr): Run loop from INDEX+1 to
6263 N_BASECLASSES; otherwise, we can still get into a loop.
6264 @@ This should be restructured to use a cleaner search strategy.
6266 Sun Jul 1 12:28:51 1990 Michael Tiemann (tiemann at masham)
6268 * dbxread.c (define_symbol,read_type): Grok GNU C++'s new
6269 abbreviation "Tt" for tags which have the same name as their
6272 Fri Jun 29 01:03:46 1990 Michael Tiemann (tiemann at masham)
6274 * symtab.c (list_symbols): add ability to set breakpoints on all
6275 the functions which match a particular regular expression.
6277 Tue Jun 26 04:26:29 1990 Michael Tiemann (tiemann at masham)
6279 * cplus-dem.c (cplus_demangle): New parameter ANSI says whether we
6280 should print ANSI qualifiers (such as `const' and `volatile').
6281 All callers changed to call with ANSI == 1, except from
6282 `check_method_stub', which uses old-style syntax.
6284 * symseg.h (struct fn_field): Remove unneccessary `args' field.
6285 * symtab.h (TYPE_FN_FIELD_ARGS): Redefined.
6287 * values.c (check_stub_method): New function.
6289 * cplus-dem.c (do_type): Handle "long long" (encoded as 'x').
6291 * dbxread.c (read_type): Handle new GNU C++ method type stubs.
6292 * valprint (type_print_base): Ditto.
6294 * symtab.c (gdb_mangle_typename): New function.
6296 Tue Jun 5 00:18:43 1990 Michael Tiemann (tiemann at gzilla)
6298 * breakpoint.c (catch_command): New function. Provides a
6299 mechanism to set breakpoints based on catch clauses.
6300 (disable_catch): Similar, but disables breakpoints on catch
6302 (delete_catch): Similar, but deleted breakpoints on catch clauses.
6304 Sun Jun 3 22:54:08 1990 Michael Tiemann (tiemann at gzilla)
6306 * blockframe.c (blockvector_for_pc): New function.
6307 * blockframe.c (block_for_pc): Changed to call
6308 `blockvector_for_pc' and get the block itself.
6310 * stack.c (catch_info): New function. Prints info about
6311 exceptions which can be caught in the current frame.
6312 * stack.c (print_frame_label_vars): New function. Similar to
6313 `print_frame_local_vars'.
6314 * stack.c (print_block_frame_labels): Prints out labels that are
6315 defined in this frame. These labels are exceptions that can be
6318 * dbxread.c: Updated to handle N_CATCH symtab types.
6320 Thu May 3 22:10:00 1990 Michael Tiemann (tiemann at teacake)
6322 * valprint.c (everywhere): TYPE_NAME (TYPE) no longer comes in the
6323 form "struct ..." for GNU C++. Don't flush any part of TYPE_NAME
6324 when printing the type.
6326 Wed May 2 22:43:04 1990 Michael Tiemann (tiemann at teacake)
6328 * valprint.c (val_print): Use `baseclass_addr' to access the
6329 baseclasses pointed to via the derived class object at VALADDR.
6331 * values.c (baseclass_addr): New function. Casts derived pointers
6332 to baseclass pointers taking virtual baseclasses and multiple
6333 inheritance into account.
6335 Sat May 5 12:39:18 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
6339 Fri May 4 12:12:55 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
6341 * breakpoint.c (watch_command, bpstat_stop_status): Deal with
6342 exp_valid_block field correctly.
6344 * infrun.c (wait_for_inferior): When checking "don't even think
6345 about breakpoints" if stop_signal == SIGTRAP && trap_expected,
6346 also check step_resume_breakpoint.
6347 Insert breakpoints and continue (not step) if
6348 step_resume_break_address != NULL, even if another_trap.
6349 If trap_expected and we enter sigtramp, then set up a
6351 If trap_expected is set when we hit the step_resume_break,
6353 When calling resume and trap_expected says tell resume to step
6354 (2 places), also check step_resume_break_address.
6356 * infrun.c (wait_for_inferior): Don't set
6357 prev_{pc,sp,func_{start,name}} before calling wait ().
6358 Do set them after exiting loop.
6359 Move their declarations outside functions.
6360 (start_inferior): Initialize them.
6362 Thu May 3 00:15:11 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
6364 * infrun.c (wait_for_inferior, after check for trap_expected > 1):
6365 Restore old code which distinguishes between trap_expected and
6366 running_in_shell, just make the latter take any non-TRAP signal,
6369 * values.c (allocate_value): Zero VALUE_OPTIMIZED_OUT flag.
6371 * Makefile.dist (pinsn.o): Use PINSN_CC to compile.
6372 xconfig/3b1 (CC,PINSN_CC): Define.
6374 * xconfig/altos, altos-dep.c: Rename altos-dep.c to altos-xdep.c.
6378 * breakpoint.c (bpstat_stop_status),
6379 infrun.c (wait_for_inferior) [SHIFT_INST_REGS]: New code.
6381 * param.h, tm-88k.h: Define ADDR_BITS_*.
6382 infcmd.c (jump_command, read_pc), infrun.c (wait_for_inferior),
6383 printcmd.c (do_one_display): Use them.
6385 * utils.c: Split #ifdef USG into a USG_UTILS and a QUEUE_MISSING.
6386 xm-88k.h: Define USG_UTILS.
6388 Wed May 2 00:05:33 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
6390 * printcmd.c (printf_command) [__INT_VARARGS_H]: New code.
6391 (printf_command): Add from_tty parameter.
6393 * valprint.c (value_print): Check VALUE_OPTIMIZED_OUT flag.
6395 * value.h: Add optimized_out field and change lazy field to
6396 char. Add macro VALUE_OPTIMIZED_OUT.
6398 * i386-pinsn.c: Change from Eirik Fuller to write to stream directly
6399 instead of stuffing things in buffers (oappend, etc).
6401 * breakpoint.c (bpstat_do_actions): If *BSP is set to NULL by
6402 execute_command, exit both loops.
6404 * Makefile.dist: Don't set TARGET_ARCH. Add .c.o rule.
6406 Tue May 1 17:07:23 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
6408 * Makefile.dist (RAPP_OBS, rapp),
