7 Sun Nov 17 16:20:53 1991 Michael Tiemann (tiemann at rtl.cygnus.com)
9 * symtab.h (struct type): Moved C++-specific fields into new type
10 `struct cplus_struct_type'. Now takes 10% less memory. Many
12 * symtab.c (init_type): Don't set fields belonging to
13 TYPE_CPLUS_SPECIFIC unless TYPE is TYPE_CODE_STRUCT.
14 * buildsym.c (read_type): Allocate TYPE_CPLUS_SPECIFIC for
16 (read_struct_type): Ditto. Also, add comments about how we can
17 deduce TYPE_VPTR_FIELDNO from inheritance info and fieldname info.
18 * coffread.c (decode_base_type): Allocate TYPE_CPLUS_SPECIFIC for
20 (read_struct_type): Ditto.
21 * dwarfread.c (struct_type): Ditto.
23 * symtab.c (read_range_type): Don't set TYPE_MAIN_VARIANT.

35 compiler from making gdb bomb out. Thanks to Ed Santiago!
37 Thu Nov 14 19:27:30 1991 Fred Fish (fnf at cygnus.com)
39 * symfile.c: Add function compact_misc_function_vector() to
40 remove duplicate misc function vector entries. See comments
41 in source for why this is necessary/desirable.
43 * dwarfread.c: Add misc function type parameter to internal
44 record_misc_function(). Remove calls to init_misc_bunches()
45 and condense_misc_bunches(), these are now done in elfread.c.
47 * elfread.c: Add support for reading bfd canonical symbol tables
48 and generating misc function vector entries for global and
49 absolute symbols. Do calls to init_misc_bunches() and
50 condense_misc_bunches() where they will enclose all calls to
51 record_misc_function(), including those in dwarfread.c.
53 Thu Nov 14 17:02:11 1991 Roland H. Pesch (pesch at cygnus.com)
55 * doc/Makefile.in: new targets gdb.me, gdb.ms, gdb.mm

74 Motorola 88000 port without tears, I mean without tdescs.
76 * m88k-tdep.c: Blow away all tdesc stuff.
77 Provide functions for all the frame-related macros in
78 tm-delta88.h. Adopt i960-style EXTRA_FRAME_INFO.
79 (examine_prologue, frame_find_saved_regs, skip_prologue): borrow
80 from i960-tdep.c and adapt to the function prologues on the 88k.
81 (read_next_frame_reg): Borrow from mips-tdep.c.
82 FIXME: frame_locals_address should go away.
84 * tm-delta88.h: Dump all the tdesc stuff.
85 Macros for all frame-related stuff call fns of same name.
86 Remove duplicated definitions. FP_REGNUM becomes same as
89 * xm-88k.h: Eliminate lots of library dependencies, now handled
90 in libiberty. Eliminate KDB nonsupport.
92 * doc/gdbint.texinfo: Add rudiments on frames. FIXME, add more.
95 * stack.c (frame_info): Mark frameless functions.
96 Print locals address (FIXME, remove if same).
97 * blockframe.c: Comment changes, FIXME after.
98 * coffread.c: Even without TDESC, need to zap "@" symbols.

102 * tdesc.c, tdesc-lib: FIXME: remove these.
104 Tue Nov 12 19:30:22 1991 John Gilmore (gnu at cygnus.com)
106 * Makefile.in: Add tdesc library support. Fixups to lint,
109 Tue Nov 12 13:43:26 1991 Per Bothner (bothner at cygnus.com)
111 * symtab.c (decode_line_1): Remove spurious call to operator_chars.
113 Allow setting breakpoints on C++ destructors.
114 * valops.c (destructor_name_p): Don't check TYPE_HAS_DESTRUCTOR,
115 since it lies. Rely on callers to catch missing destructors.
116 * symtab.c (decode_line_1): For example (see above), here.
117 * buildsym.c, symtab.h: Remove TYPE_FLAGS_HAS{CON,DE}STRUCTOR
118 flags since they are no longer used.
120 Fixes to support C++ methods with functional parameters.
121 * c-exp.y (func_mod rule): Allow (and ignore) list of parameter
122 types in a function type.
123 * eval.c (parse_and_eval_type), value.h: New function,
124 parse_and_eval_type, is based on old code from check_stub_method.
125 But don't actually evaluate the cast, since that calls
126 value_cast(), whcih may fail. Just extract the type
127 from the parsed expression.
128 * values.c (check_stub_method): While looping through the
129 arguments, adjust depth *after* parameter has been handled.
130 Replace call and setup of parse_and_eval with new function
133 Tue Nov 12 09:40:07 1991 Fred Fish (fnf at cygnus.com)
135 * utils.c, rem-multi.shar: Remove fixed arg count version of

139 core.c, dwarfread.c, gould-xdep.c, infcmd.c, language.c,
140 m88k-xdep.c, main.c, printcmd.c, pyr-xdep.c, source.c,
141 sun386-xdep.c, symm-xdep.c, umax-xdep.c, values.c, xcoffread.c:
142 Change all instances of use of fixed args concat() to variable
143 args concat() now located in libiberty.
145 Tue Nov 12 07:23:46 1991 John Gilmore (gnu at cygnus.com)
147 * Makefile.in: Add xcoffread.c, xcoffexec.c.
148 * xcoffread.c: New file for handling AIX mangled-coff files.
149 * xconfig/rs6000, tconfig/rs6000: New files.

151 * rs6000-pinsn.c, rs6000-tdep.c, rs6000-xdep.c, tm-rs6000.h,
152 xm-rs6000.h, rs6k-opcode.def, rs6k-opcode.h: New files.
153 * xcoffexec.c: New file for handling AIX shared libraries.
155 Mon Nov 11 19:14:31 1991 Fred Fish (fnf at cygnus.com)

158 (and possibly arguments to) the program that generated a core
161 * elfread.c: Remove the register_addr() stub now that it is no
164 * procfs.c: Move misplaced #endif for ATTACH_DETACH. Add new
165 fetch_core_registers() function for core file support.
167 Sat Nov 9 13:37:57 1991 Fred Fish (fnf at cygnus.com)
169 * dwarfread.c (dwarf_psymtab_to_symtab): Remove leftover call
170 to do_cleanups() which resulted from a previous change.
172 * elfread.c: Re-enable compilation of register_addr() stub
173 whenever it is not supplied by coredep.c
175 Sat Nov 9 00:40:32 1991 John Gilmore (gnu at cygnus.com)
177 Add tracking of object files (that contain symbols) to gdb.
178 This includes a "struct objfile" that owns symtabs and psymtabs
179 that were read in from that binary file.
181 * symfile.h: Add struct objfile. Add pointer to the objfile
182 into the struct sym_fns.
183 Replace global `symfile' and `symfile_mtime' with
184 `symfile_objfile'. Add global object_files chain.
186 * symfile.c: Move param.h above symtab.h.
187 (sort_misc_function_vector): Add.
188 (syms_from_objfile): Was syms_from_bfd.
189 (symfile_open): Now returns objfile.
190 (allocate_objfile): New.
191 (free_objfile): New, replacing free_all_.*symtabs.
192 (symfile_init): Takes objfile arg, puts it in sym_fns result.

194 (allocate_symtab): Takes objfile as new parameter, chains them.
195 Handle INIT_EXTRA_SYMTAB_INFO.

198 * dbxread.c: Make more errors into complaints.
199 (push_subfile, pop_subfile): Move to buildsym.c.
200 (dbx_symfile_read, dbx_symfile_init, fill_symbuf, read_dbx_symtab,
201 start_psymtab, psymtab_to_symtab_1, read_ofile_symtab,
202 dbx_psymtab_to_symtab, ): Use bfd ops, don't use file descriptor.
203 Pass objfile. Change callers.
204 (fill_symbuf, SWAP_SYMBOL): Take bfd as arg.
205 (read_dbx_symtab): Just wipe out new symbols, not all, on error.
206 (end_psymtab): Blow away psymtab if empty.

211 * buildsym.c (end_symtab): Pass objfile.
212 (dbx_lookup_type): Handle null typevector.
213 (dbx_alloc_type): Check file number, not sym number, for -1.
214 (find_symbol_in_list): Add for xcoffread.
215 (start_symtab): Default typevector is empty. Keep reusing same
217 (end_symtab): Take objfile argument and pass it to
218 allocate_symtab. Don't make a symtab if no blocks or symbols.
219 Handle empty typevector.
220 (push_context): New function for context stack nesting.
221 (read_type): Mark FIXME where we need to reintroduce type smashing.
223 * buildsym.h (pop_context): Macro, paired with push_context.
224 (subfile_stack): Move here from dbxread.c.
226 * coffread.c (end_symtab, read_coff_symtab): Take and use objfile arg.
227 (read_coff_symtab): Cleanup by freeing objfile, not all symtabs.
229 * mipsread.c (read_mips_symtab, parse_partial_symbols, parse_fdr,
230 new_psymtab, new_symtab): Take and use objfile arg.
232 * dwarfread.c (scan_compilation_units, start_psymtab,
233 process_dies, end_symtab, dwarf_build_psymtabs,
234 read_lexical_block_scope, read_func_scope, read_file_scope): Take
235 and use objfile argument.
236 (psymtab_to_symtab_1, read_ofile_symtab): Don't take or use file
237 descriptor. Use BFD internal functions instead.
238 (end_symtab): Call global allocate_symtab.
240 * elfread.c, target.c: Minor changes to accommodate objfiles.
241 * symtab.h: partial_symbol_table has no symfile_name member now.

243 (struct symtab): Add objfile * and objfile_chain * of symtabs.
244 (struct partial_symtab): Add objfile * and objfile_chain * of
245 psymtabs. Remove symfile_name.
247 * symmisc.c: Lose free_all_symtabs, free_all_psymtabs.
248 (printsyms_command): Rename from print_symtabs. Add selective
249 listing if 2nd argument given. Print objfile info.
250 (printpsyms_command): Rename from print_partial_symtabs. Ditto all.
251 (printobjfiles_command): New; prints objfiles lists, and checks
252 for consistency of symtab, psymtab, and objfile lists.
254 * symfile.h, symfile.c, symtab.h: Lint
256 Fri Nov 8 23:38:48 1991 John Gilmore (gnu at cygnus.com)

260 * expprint.c (print_subexp, UNOP_MEMVAL case): Lint.
261 * inflow.c (new_tty): Use USE_O_NOCTTY #define.
262 * language.c, printcmd.c (print_scalar_formatted), signame.c,
265 Thu Nov 7 18:26:15 1991 Steve Chamberlain (sac at rtl.cygnus.com)
267 * Makefile.in: link with libiberty after libreadline, since
268 readline might want something in libiberty.
269 * m88k-xdep.c: Fixed the register offsets in the ptrace_user
270 struct for BCS 88k machines.
271 * xm-m88k.h: don't define USIZE if already defined.
272 * configure.in: Added delta88 target.
274 Thu Nov 7 04:51:19 1991 John Gilmore (gnu at cygnus.com)
276 * am29k-pinsn.c, am29k-opcode.h: Fix decoding of mtacc, dmac, fmac.
278 * tm-*.h: Remove READ_DBX_FORMAT, COFF_FORMAT, and
279 READ_MIPS_FORMAT, which have been unused since BFD. Still
280 remaining is COFF_NO_LONG_FILE_NAMES.
281 * tm-sun3.h, tm-altos.h: Remove detritus accidentally left from
282 function calling code moved to m68k-tdep.c.
284 Wed Nov 6 17:21:59 1991 John Gilmore (gnu at cygnus.com)
286 * coffread.c: Eliminate c_nsyms in favor of c_naux.
287 Complain if no auxents on .bf and .ef FCN symbols, and assume
288 lots of line numbers.
289 (init_linenos, enter_linenos): Use a sentinel at the end of the
290 read-in linenos, to make for a fast, safe loop-end test.
292 Wed Nov 6 02:54:08 1991 Steve Chamberlain (sac at cygnus.com)
294 * coffread.c (read_coff_symtab): coffread used to rely on the
295 x_sym.x_misc.x_lnsz.x_lnno field giving the # of linnos in a
296 function. Two of the formats I'm using (29k and 88k) don't seem to
297 set it. Ths patch to fcn_last_line and (enter_linenos) is an
298 attempt to use the actual size of the linno table in the file to set
299 the number of linenos to process.
301 Tue Nov 5 22:47:46 1991 Steve Chamberlain (sac at cygnus.com)
303 * Makefile.in: put a - infront of the mv y.tab.c c-exp.tab.c and
304 mv y.tab.c m2-exp.tab.c, so that if bison is used, and the files
305 are created in place, so the mv fails, then the make continues.
307 Tue Nov 5 16:47:47 1991 Per Bothner (bothner at cygnus.com)
309 Add C++ as a separate language.
310 * defs.h (enum language): Add language_cplus.
311 * dwarfread.c (end_symtab): Support language_cplus.
312 * c-exp.y: Add new struct language_defn cplus_language_defn.
313 Don't set c to be the default language (see main.c).
314 * c-exp.y (yylex): Only look for field of this if
315 language is C++. (First difference from C!)
316 * language.c: Add case branches for C++ (currently, all
317 the same as C). Also, add c++ to "usage" note for "set lang".
318 * valprint.c (typedef_print). Add case branches for C++.
319 * main.c (main): New way to set initial language: Look at
320 file extension of psymtab containing main(). (Same as we
321 do for symtabs, but avoid loading the symtab yet.)
322 * symtab.c: New routine find_main_psymtab(), used by main()
323 to set initial language.
324 * symfile.c (allocate_symtab): Move code for mapping file
325 extensions-> languages to new deduce_language_from_filename().
327 Fix a C++ problem when looking for methods in super-classes.
328 There was confusion between base and derived types.
329 * valops.c (value_fn_field): Change function interface.
330 * values.c: Use new value_fn_field interface.
332 Mon Nov 4 10:49:33 1991 Per Bothner (bothner at cygnus.com)
334 * infrun.c: Fixed typo in comment.
335 * utils.c: All the v*fprintf emulation is now in libiberty,
336 so we can get rid of some junk.
337 * xm-sun3os4.h, xm-sun4os4.h, xconfig/decstation, xconfig/i386sco,
338 xconfig/sun3os4, xconfig/sun4os4: Don`t need HAVE_STRSTR any more.
339 * m68k-pinsn.c (print_insn_arg): Support BB/BW/BL
340 type operands, as used by branch instructions.
341 * gmalloc.c: Fix prototype of memcpy.
342 * elfread.c: Comment out register_addr, since it conflicts
343 with the one in coredep.c.
344 * buildsym.h: Remove extern declarations of two functions
345 that are really static in buildsym.c.
346 * tm-mips.h: Add symbolic names for more registers.
347 * mips-xdep.c (store_inferior_registers): Use new register names.
348 * xm-mips.h: Simplify REGISTER_U_ADDR, since it is now
349 only used for core files, not ptrace. Therefore,
350 the KERNEL_U_ADDR hack is no longer needed.
351 The mapping to ptrace number is now in in mips-xdep.c.
352 * mips-xdep.c: Define REGISTER_PTRACE_ADDR (using the
353 mapping from the old REGISTER_U_ADDR), and use it
354 in {fetch,store}_inferior_registers.
355 * mipsread.c: Rename #include ecoff.h to new name coff-mips.h.
356 * mips-tdep.c (mips_push_dummy_frame, mips_pop_frame):
357 Save/restore FP regs correctly (?).
358 * dbxread.c: Remove duplicate define_symbol and type_synonym_name
359 (these had been previously moved to buildsym.c).
360 Hence, define_symbol becomes extern instead of static.
361 * buildsym.c (read_struct_type): Comment out bogus handling
362 of C++ operator methods. Minor hacking of reading of class
363 contexts. Make define_symbol non-static, so dbxread.c can call it.
365 Fri Nov 1 11:05:47 1991 John Gilmore (gnu at cygnus.com)
367 * mipsread.c (read_mips_symtab, read_the_mips_symtab): Use real
368 filename with error messages.
369 * stack.c (frame_select_command): Rename to select_frame_command
370 to avoid "fr" and "fra" having nonunique completions.
371 * symfile.c (sort_symtab_syms): Ignore sort of zero symtab *.
372 (symfile_init): Print file format name when unable to handle it.
373 (free_named_symtabs): Use BLOCKVECTOR rather than obsolete BLOCKLIST.
374 * symmisc.c (free_symtab): Only free linetable if nonzero.
375 * symtab.h: Remove obsolete BLOCKLIST macros.
377 Thu Oct 31 18:12:43 1991 Stu Grossman (grossman at cygnus.com)
379 * infrun.c (wait_for_inferior): another stepi/nexti fix. Ensure
380 that stop_step is 1 at bottom of main loop. I don't know why this
381 needs to be done, but it helps me sleep better at night.
383 Sun Oct 27 18:18:39 1991 Stu Grossman (grossman at cygnus.com)
385 * main.c (initialize_history): Read history after reading all
388 Sun Oct 27 14:09:25 1991 John Gilmore (gnu at cygnus.com)
390 * buildsym.c: Break out initial malloc sizes.
391 (record_line): Record directly in a subfile. Alloc on demand.
392 (compare_line_numbers): Add from xcoffread.c.
393 (end_symtab): New params say whether to sort pendings and
394 linetable. Patch block stabs if defined. Shrink linetable before
395 allocating the symtab.
396 * buildsym.h: Delete line_vector* and prev_line_number. Add
397 global_stabs and file_stabs for xcoffread.
398 * dbxread.c (start_subfile): Move to buildsym. Change above calls.
399 * symtab.h: LINETABLE(symtab) can now be null. Zap LINELIST.
400 * symmisc.c, symtab.c: Cope with null LINETABLEs.
402 * blockframe.c: Pass fromleaf to INIT_EXTRA_FRAME_INFO.
403 * tm-29k.h, tm-88k.h, tm-i960.h, tm-irix3.h, tm-mips.h, tm-pyr.h,
404 tm-sparc.h: Accept fromleaf parameter.
405 * c-exp.y (yyerror): Pass error message if given.
406 * configure.in: Add rs6000 host and target.
407 * inflow.c (new_tty): O_NOCTTY kludge for RS/6000.
408 * symfile.h (entry_point): Add.
410 Sat Oct 26 00:16:32 1991 John Gilmore (gnu at cygus.com)
412 * buildsym.c: New file. Breaks out symbol-table-building routines
413 from dbxread.c, so they can be shared with xcoffread.c.
414 * buildsym.h: New file. Declarations for buildsym.c users.
415 * dbxread.c: Remove large chunks into buildsym.c.
416 * Makefile.in: Add buildsym.c and buildsym.h.
418 * symfile.c (syms_from_bfd): New routine.
419 (add_symbol_file): Call it to do the real work.
420 (syms_from_bfd): Initialize entry_point before calling symfile_init.
421 * symtab.h, symfile.c, coffread.c, mipsread.c, dwarfread.c:
422 Avoid declaring or setting entry_point (symfile.h & symfile.c cope).
424 Fri Oct 25 10:58:16 1991 Mark Eichin (eichin at cygnus.com)
426 * cplus-dem.c (cplus-demangle): added support for templates, static
427 data, and the new (correct) mangling for destructors.
429 * dwarfread.c: (dwarfwarn): created a varargs version of
430 dwarfwarn, for non __STDC__ compilers.
432 * c-exp.y: (yylex): added match for "template" token.
433 (typebase): added TEMPLATE name '<' type '>' clause, for explicit
434 specification of template types.
436 * symtab.c: (lookup_template_type): new function for finding
437 templates in symbol table.
438 (type_name_no_tag): changed to explicitly check for s/u/e at the
439 beginning of the symbol - if it is a template, none of these will
440 be there (but the name will still contain spaces.)
442 Fri Oct 25 18:59:32 1991 Per Bothner (bothner at cygnus.com)
444 Various fixes to improve g++ debugging.
445 * symtab.h: Add is_const and is_volatile flags for each method.
446 These are bit fields - take their space from voffset,
447 which shrinks to 30 bits. Since voffset is now a bitfield,
448 make it unsigned for portability. This changes its interpretation
449 slightly: Static methods now have voffset 1 instead of -1,
450 and virtual offsets start at 2, not 1.
451 * symtab.c: Renamed gdb_mangle_typename to gdb_mangle_name,
452 since it now returns an entire magled method name, not just
453 the type part. This avoids some duplication.
454 It also allows us to correctly mangle const and volatile
455 methods (using the new is_const and is_volatile bit fields
457 * valprint.c (type_print_base), values.c (check_stub_method):
458 Simplify by using new gdb_mangle_name.
459 * values.c (value_headof): Fix to correctly handle single
460 inheritance (actually two fixes, either of which suffices).
461 * dbxread.c (read_struct_type): Handle const and volatile
463 * dbxread.c (read_struct_type): Yet one more place where
464 we must handle '\\' continuations.
465 * valprint.c (vtbl_ptr_name): Add final '\0'.
467 Fri Oct 25 16:06:38 1991 Stu Grossman (grossman at cygnus.com)
469 * tm-sparc.h, tm-68k.h (EXTRACT_RETURN_VALUE): fix output of
470 short return values for sparc and 68k. Patch from Paul Eggert.
472 * coffread.c, coredep.c, i386-xdep.c: install patches for
473 SysV/386 3.2 from Mauro DePalma.
475 Fri Oct 25 02:02:13 1991 John Gilmore (gnu at cygnus.com)
477 * core.c (core_file_info), exec.c (exec_file_info): Print file
478 type. Use printf_filtered.
480 * valops.c (value_fetch_lazy): Avoid 0-length fetches.
482 Thu Oct 24 23:06:40 1991 Fred Fish (fnf at cygnus.com)
484 * dwarfread.c: Add casts to remove compiler warnings.
486 * tm-3b1.h, tm-68k.h, tm-altos.h, tm-amix.h, tm-hp300bsd.h,
487 tm-hp300hpux.h, tm-isi.h, tm-news.h, tm-pn.h, tm-sun2.h,
488 tm-sun3.h: Remove locally duplicated code for calling functions
489 in the inferior. The only differences were in the specific trap
490 vectors used and whether or not an fpu was present. These are
491 now handled by appropriate definitions of BPT_VECTOR and
492 HAVE_68881 respectively. Other minor obvious cleanups.
494 * valops.c: Correct a minor misspelling.
496 * utils.c: Remove local BSD/USG hacks that are now in libiberty.
498 * dwarfread.c: Remove prototype for dwarfwarn. Does not work
501 Thu Oct 24 09:33:44 1991 John Gilmore (gnu at cygnus.com)
503 * stack.c (frame_command): Always print. Use new
504 frame_select_command to select a frame without printing.
506 * dwarfread.c: Use <varargs.h>, since <stdarg.h> is not portable.
508 Thu Oct 24 01:32:51 1991 Fred Fish (fnf at cygnus.com)
510 * dwarfread.c: New file for DWARF debugging format support.
512 * elfread.c: New file for ELF object file format support.
514 * procfs.c: New file for SVR4 /proc (process file system) support.
516 * tm-amix.h, xm-amix.h, tconfig/amix, xconfig/amix: New files for
519 * xm-svr4.h, tm-svr4.h: New files for SVR4 support.
521 * xm-m68k.h: New file for host machines with m68k cpu.
523 * Makefile.in: Add elfread.c and dwarfread.c to SFILES_MAINDIR.
524 Add elfread.o and dwarfread.o to OBS.
526 * symfile.h: Add "elf" to list of supported formats in comment.
528 * c-exp.y, defs.h, symtab.h, valprint.c: Add three new builtin
529 types to gdb, builtin_type_long_double, builtin_type_complex, and
530 builtin_type_double_complex. Add and use new TARGET_SHORT_BIT,
531 TARGET_INT_BIT, TARGET_LONG_BIT, TARGET_FLOAT_BIT,
532 TARGET_DOUBLE_BIT, TARGET_LONG_DOUBLE_BIT, TARGET_COMPLEX_BIT, and
533 TARGET_DOUBLE_COMPLEX_BIT, as the sizes in bits of the indicated
534 types on the target machine (ala the existing TARGET_LONG_LONG_BIT).
536 * infrun.c: When using SVR4 /proc interface instead of ptrace(),
537 call proc_set_exec_trap() to setup child to stop at first instruction.
539 * inftarg.c: When using SVR4 /proc interface, call proc_wait()
542 * m68k-tdep.c: Add new routines supply_gregset(), fill_gregset(),
543 supply_fpregset(), and fill_fpregset(), which are machine
544 dependent support routines for SVR4 /proc interface.
546 * utils.c: Add warning_setup() and warning(). Warning() behaves
547 the same as error() except that it returns normally rather than
548 jumping back to command level. Modules that don't want to call
549 warning() for some reason, but want to produce their own warnings,
550 can call warning_setup() to ensure compatibility with the way
551 warning() and error() deal with the terminal.
553 * symtab.c: Make internal errors produce more useful messages.
555 * tm-68k.h: Move code that is duplicated in almost every single
556 m68k based machine's configuration files to this common file.
557 Duplications in the configuration files still need to be removed
560 * infrun.c (child_create_inferior): System V versions must call
561 setpgrp() with no arguments, to comply with prototyping typically
564 * munch: Add support for SVR4 style nm output.
566 * dbxread.c, mipsread.c symmisc.c, symtab.c: Remove the object
567 file specific fields from the partial symbol table structure and
568 replace them with a pointer to private data for each different
569 flavor of object file reader to initialize appropriately.
571 Wed Oct 23 09:38:20 1991 John Gilmore (gnu at cygnus.com)
573 * xconfig/sun[34]os4: Add note about strstr botch on sunos4.0.3c
576 * mipsread.c (fixup_undef_type): New function. If a struct /
577 union / enum is defined in a header file but nowhere else used,
578 (by typedefing, pointer referencing or declaration) the mipsread code
579 builds the complete tree for the structure but leaves its code as
580 TYPE_CODE_UNDEF as it doesn't know what kind of aggregate it is.
581 Guess its type based on the details of the members.
583 Tue Oct 22 18:04:32 1991 Stu Grossman (grossman at cygnus.com)
585 * infrun.c (wait_for_inferior): Check return value from
588 Mon Oct 21 17:47:03 1991 Stu Grossman (grossman at cygnus.com)
590 * infrun.c (wait_for_inferior): fix stepi/nexti that was broken
591 by my last edit to this routine.
593 Mon Oct 21 14:27:43 1991 John Gilmore (gnu at cygnus.com)
595 * tm-sun3.h (FIX_CALL_DUMMY): problem with cross debugging.
596 FIX_CALL_DUMMY does unaligned accesses and/or forgets to byte swap
597 the values before putting them into the dummy code. (From Peter
600 Mon Oct 21 10:04:39 1991 Steve Chamberlain (steve at rtl.cygnus.com)
602 * configure.in: added ebmon target.
604 Wed Oct 16 22:49:58 1991 John Gilmore (gnu at cygnus.com)
608 * Makefile.in: Roll VERSION to 4.2.
609 * README, TODO, WHATS.NEW: Update.
611 * core.c (core_open): Improve error message for bad file.
612 Pass .reg virtual memory address to fetch_core_registers to help
613 it find the registers in the core-file header.
614 * coredep.c (fetch_core_registers): Take new argument, use it,
615 and pass it to register_addr to locate the block of registers.
616 * xm-mips.h: Update KERNEL_U_ADDR for new scheme. Cleanup a bit.
618 * dbxread.c (read_dbx_symtab, process_one_symbol): Handle
619 Sequent N_FN_SEQ like everybody else's N_FN.
621 * main.c: Circumvent SCO cc bug with #if !!defined(USG).
622 * tm-i386v.h: #endif guck.
623 * xconfig/i386*: Remove -Dgetpagesize()=4096 kludge.
624 * xconfig/i386sco: Add HAVE_STRSTR to avoid ANSI bdeath.
625 * xconfig/tahoe: Add REGEX, which seems to be missing.
627 * coredep.c: Add <sys/types.h> for SCOnix.
628 * dbxread.c (read_dbx_symntab): Avoid coredump on malformed file.
629 * printcmd.c (print_formatted): Flush output before disassembly.
631 Tue Oct 15 20:12:32 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
633 * doc/refcard.tex (sec "Working Files"): consistent metavars and
634 other improvements, due to comments by François Pinard
635 (pinard@iro.umontreal.ca)
637 * doc/gdb.texinfo (appendix "Installing GDB"): changes in
638 configure, and improvenets related to Pinard's refcard comments
640 Tue Oct 15 08:45:12 1991 John Gilmore (gnu at cygnus.com)
642 Changes from Fred Fish:
643 * tm-68k.h (FPI_REGNUM): Add.

647 * inflow.c: Handle TIOCGLTC_BROKEN for Amiga.
650 * values.c (show_convenience): Use printf_filtered.
651 * main.c (define_command): Check result of lookup_command for
653 (echo_command): Use printf_filtered, and force output out.

657 * i387-tdep.c (double_to_i387): Fix typo for double_to_ieee_extended.
658 * utils.c (_initialize_utils): If !ISATTY, don't paginate.
659 * configure.in, tconfig/decstation, xconfig/decstation: Rename
660 dec3100 to decstation.
662 Mon Oct 14 13:37:50 1991 Roland H. Pesch (pesch at cygnus.com)
664 * doc/gdb.texinfo: Catch up to changes recorded here in ChangeLog
665 (nodes Continuing and Stepping; Memory; Targets) clarifications
668 Fri Oct 11 23:27:06 1991 John Gilmore (gnu at cygnus.com)
670 * tm-{irix3,mips,nindy960,pn,symmetry,vx960}.h: Move
671 REGISTER_U_ADDR to corresponding xm- file. Sugg. by Peter Schauer.
673 * symmisc.c (print_partial_symtabs): Add printpsyms debug cmd.

676 generic routines for calling inferior functions.
678 * blockframe.c (inside_main_scope, inside_entry_scope): New.
680 * copying.awk: Filter formfeeds out of copying & warrantee.
681 Make them available as `show copying' and `show warrantee' also.
682 * main.c (print_gnu_advertisement): Advt `show' commands.
684 Thu Oct 10 17:25:47 1991 John Gilmore (gnu at cygnus.com)
686 * mach386-xdep.c: Even when cross-compiling, leave in the
687 core-file reading code.
688 * core.c (get_core_registers): Avoid coredump if no .reg section.
690 Wed Oct 9 17:03:34 1991 John Gilmore (gnu at cygnus.com)
692 * mipsread.c, coffread.c: initialise TYPE_VPTR_FIELDNO to -1.
693 This avoids coredumps under `set print object on' in value_headof
694 (called erroneously by value_from_vtable_info) for `p &struct'
695 or `p *struct'. From Peter Schauer.
697 Mon Oct 7 00:06:52 1991 John Gilmore (gnu at cygnus.com)
699 * Makefile.in: Roll version to 4.1.2.
700 * dbxread.c: Use aout64.h, not a.out.gnu.h. Get external symbol entry
701 size from BFD (but, FIXME, we don't yet read external nlists's and
702 convert them to internal nlists's before handling them -- we still
703 assume they have the same size and alignment.) Use SET_NAMESTRING
705 * exec.c (exec_file_command): Move dead coff-encapsulation code
707 * m88k-tdep.c, m88k-xdep.c: Remove encap test and #inc <a.out.h>.
709 Fri Oct 4 22:30:06 1991 John Gilmore (gnu at cygnus.com)
711 * configure.in, tm-i386v.h, xm-i386v.h: Intel 386 Mach host port.
712 * xm-i386mach.h, mach386-xdep.c, xconfig/i386mach: New files.
714 Fri Oct 4 17:04:31 1991 Per Bothner (bothner at cygnus.com)
716 More patches from Peter Schauer <pes@regent.e-technik.tu-muenchen.de>:
717 * mips-xdep.c (store_inferior_registers): Don't try to
718 write the (pseudo) FP.
719 * mipsread.c (parse_partial_symbols): Improved algorithm for
720 setting pst->texthigh.
722 Fri Oct 4 16:47:32 1991 Roland H. Pesch (pesch at cygnus.com)
724 * doc/Makefile: make TEXINPUTS include . everywhere
726 Fri Oct 4 00:35:56 1991 John Gilmore (gnu at cygnus.com)
728 * coffread.c, dbxread.c, symfile.c, symmisc.c, symtab.h: Remove
729 vestiges of typevectors, which were for symsegs and are no longer
730 used. (From a question by Eliot Dresselhaus
731 <dresselh@RFT30.nas.nasa.gov>).
733 Thu Oct 3 09:33:26 1991 John Gilmore (gnu at cygnus.com)
735 * dbxread.c, coffread.c: static-ize functions that were
736 gratuitiously external. (From Fred Fish.)
738 * c-exp.y: sym->class to SYMBOL_CLASS (sym).
740 * dbxread.c (dbx_lookup_type): Keep doubling size of typevector
741 until it is large enough.
743 * dbxread.c (read_type): Handle error case slightly better.
744 Make complaint message not C++-specific.
746 Wed Oct 2 17:21:07 1991 Stu Grossman (grossman at cygnus.com)
748 * infrun.c (wait_for_inferior): Fix step/next so that you only
749 stop at the beginning of a new line. This fixes various problems
750 with for loops, nested if-else's and switch statements.
752 Tue Oct 1 06:33:55 1991 John Gilmore (gnu at cygnus.com)
754 * symtab.c (lookup_symtab_1, lookup_symbol): "fatal" errors
755 between symtabs and psymtabs become ordinary error()s.
757 * dbxread.c (read_dbx_symtab): Relocate end_of_text_addr
758 properly, making "end pc" correct in shared lib psymtabs.
759 (From Guy Harris <guy@auspex.com>.)
761 Mon Sep 30 13:15:31 1991 John Gilmore (gnu at cygnus.com)
763 * dbxread.c: Enable, but soften, const_vol_complaint.
764 (read_dbx_symtab): N_STSYM and N_LCSYM define static vars.
765 Ditto Gould N_NBSTS and N_NBLCS. Also, all types in the psymtab
766 should be file-scope, not global.
767 (read_struct_type): Remove ancient multiple-inheritance warning.
768 (read_range_type): Check base type, complain & patch if undefined.
769 * stack.c (frame_info): Demangle the function name in `info stack'.
772 Sat Sep 28 10:02:33 1991 John Gilmore (gnu at cygnus.com)
774 * eval.c (evaluate_subexp_for_address): Don't use
775 TYPE_POINTER_TYPE directly (it might be zero if this type has
776 never had a pointer created before); use lookup_pointer_type.
777 * symtab.c (lookup_method_type): Arguments were swapped in all
778 callers, so fix it here. I'm amazed this worked at all!
780 Fri Sep 27 18:09:31 1991 John Gilmore (gnu at cygnus.com)
782 * c-exp.y, m2-exp.y: Define more yysymbols that happen to be
783 "bss" rather than "data" symbols, but which still conflict.
786 * coffread.c (coff_symfile_read): Use xmalloc, not malloc.
787 * core.c (core_files_info): Shorten output.
788 * exec.c (exec_files_info): Ditto.
789 (build_section_table): Ignore zero-length sections.
790 * language.c, printcmd.c: Lint.
791 * language.h (get_frame_language): Declare.
792 * saber.suppress: update.
793 * stack.c (find_relative_frame): Remove complex code that was

800 * valprint.c (val_print, type_print_base): TYPE_CODE_RANGE less
803 * nindy-tdep.c (nindy_frame_chain_valid): Use lookup_misc_func.
804 (Reported by Mark Peek <mark@imagen.com>.)
806 * solib.c (solib_map_sections): Relocate all sections, even
807 though only the text section's size is tracked. Mark ld_text
808 for eventual elimination as we generalize to N sections.
810 * infrun.c (wait_for_inferior): Don't check if the PC is in a
811 call_dummy if we were stopped by a random signal that is being
812 passed to the program. This produced wierd results when calling
813 functions in the inferior and signals (e.g. SIGALRM) were in use.
815 Tue Sep 24 18:05:30 1991 John Gilmore (gnu at cygnus.com)
817 * infrun.c (IN_SIGTRAMP): Not parenthesized properly.
818 Bugfix from Paul Eggert <eggert@twinsun.com>.
819 * tm-ultra3.h (IN_SIGTRAMP): Ditto.
820 * valprint.c (print_floating): Print 9 digits for IEEE floats.

829 Fri Sep 20 16:10:52 1991 John Gilmore (gnu at cygnus.com)
833 * Makefile.in (VERSION): Set to 4.1.
834 * language.c (set_language_command): Print useful help message,
835 and restore the language string after giving help.
836 * valprint.c (typedef_print): Print typedef in C or M2.
837 * symtab.c (list_symbols): Use it.
838 * main.c (main): Avoid any output before (gdb) prompt when -q.
839 * language.c (set_language_command): Handle errors by restoring
840 the language string to its current state (fix from A. Beers).
841 * doc/gdbint.texinfo: Roll in information from README. Rearrange
842 "how to install" and "how to print the doc" stuff so it drops
844 * configure.in: Rename rtpc CPU to romp to match config.sub.
845 * README, WHATS.NEW, TODO: Update for gdb-4.1.
847 Fri Sep 20 17:39:14 1991 Roland H. Pesch (pesch at cygnus.com)
849 * doc/gdb.texinfo: Updates from ChangeLog. set/show write,
850 autoloading shared libs, copyright etc on GDB startup, clean up $_
851 and $__ index refs, set/show listsize and related updates to list
852 cmd. New host/target configs.
854 Fri Sep 20 15:46:00 1991 Roland H. Pesch (pesch at cygnus.com)
856 * doc/Makefile: generate aux version-no file doc/gdbVN.m4
857 from main Makefile.in version definition
858 doc/gdb.texinfo: use version recorded in doc/gdbVN.m4 for current
860 Makefile.in (setup-to-dist): generate doc/gdbVN.m4
862 * doc/gdb.texinfo: merge new language-switching and lang-specific
865 Fri Sep 20 15:00:57 1991 Per Bothner (bothner at cygnus.com)
867 * mcheck.c: Add __ONEFILE kludge to allow compilation by non-ANSI
868 compilers (which may lack stddef.h).
870 Fri Sep 20 13:29:42 1991 John Gilmore (gnu at cygnus.com)
872 * dbxread.c (read_dbx_symtab, process_one_symbol): N_FN and
873 N_WARNING are the same except for the N_EXT bit, so just use their
874 values alone, rather than OR-ing them with N_EXT.
876 Fri Sep 20 12:27:55 1991 Stu Grossman (grossman at cygnus.com)
878 * mipsread.c (parse_lines): Deal with negative extended line
881 * c-exp.y, m2-exp.y: #define yyerrflag and yynerrs to avoid
882 global symbol conflicts.
884 Fri Sep 20 02:28:15 1991 John Gilmore (gnu at cygnus.com)
886 * .gdbinit: Move 'set complaints' to top, so it runs even in
887 case we aren't debugging GDB.
888 * language.c (_initialize_language): Fix type check and range
889 check documentation strings.
890 * utils.c (!HAVE_VPRINTF): Define vfprintf as a function, so
891 language.c can use it. (Though language.c should really not be
892 handling warnings/errors the way it does, FIXME.)
893 * symtab.c (lookup_primitive_type): const lint.
895 Bugfix from Peter Schauer:
896 * source.c (lines_to_list): Make signed, to avoid comparison
897 going unsigned and complaining that -3 is too high for 21 lines.
898 * stack.c (lines_to_list): Ditto.
900 Thu Sep 19 23:33:41 1991 John Gilmore (gnu at cygnus.com)
902 * Makefile.in (HFILES): Add minimon.h.
903 (VERSION): Roll version number to 4.0.95.
904 (gdb.tar.Z, make-proto-gdb.dir, setup-to-dist, gdb-XXX.tar.Z):
905 New rules for building distributions. Normal distribution
906 is built by doing `make -f Makefile.in gdb.tar.Z' in the directory
907 one level up from here; it calls make-proto-gdb.dir to build a
908 directory `proto-gdb' which is an image of the release. The old
909 `gdb.tar.Z' rule still works too.
910 * config.sub, configure: Roll in latest from ..
912 Thu Sep 19 17:41:24 1991 Roland H. Pesch (pesch at cygnus.com)
914 * doc/gdbint.texinfo: Reorder contents; reorganize new-host,
915 new-target, and new-config chapters; fix minor typos; come closer
916 to usual GNU markup conventions for @file @samp @code @var.
918 Thu Sep 19 17:04:12 1991 Per Bothner (bothner at cygnus.com)
920 Patches from Peter Schauer <pes@regent.e-technik.tu-muenchen.de>:
921 * mipsread.c (parse_partial_symbols): Enter the name of all
922 structs/unions... into the psymtab so we can access them if the
923 symtab is not read in.
924 * mips-tdep.c: Remove some unneeded #includes.
925 * xconfig/dec3100: Add HAVE_STRSTR.
927 Thu Sep 19 15:14:23 1991 John Gilmore (gnu at cygnus.com)
929 * Makefile.in: Circumvent Sun Make bug on *-exp.tab.o.
930 * c-exp.y, m2-exp.y: Lint.
931 * m2-exp.y: Avoid using yytname[] which is a Bison-ism.
932 * valprint.c (val_print_fields): Check for stub type.
933 * mipsread.c (_initialize_mipsread): Avoid using
934 builtin_type_void at initialize time.
935 (mipscoff_symfile_read): use it now.
937 Wed Sep 18 15:55:51 1991 John Gilmore (gnu at cygnus.com)
939 Merge multiple-language support, and partial Modula-2 support,
940 from Andrew Beers <beers@cs.buffalo.edu>.
942 * i387-tdep.c: New file, consolidates most 80387 support,
943 and eliminates host dependency on double<->extended conversions.
944 * i386-xdep.c, symm-xdep.c: Remove most 387 support.
945 * xconfig/i386{sco,v,v-g,v32,v32-g}: Now need i387-tdep.o.
947 * symfile.c (allocate_symtab): New fn, consolidates the work
948 of allocating and initializing a new struct symtab. Set the
949 language of the symtab based on its filename extension.
950 * symfile.h: Declare it.
951 * mipsread.c (new_symtab): Use it. Minor formatting changes.
952 * dbxread.c (end_symtab): Use it.
954 * mipsread.c (parse_symbol, case stParam and stProc): Add #if 0'd
955 code for saving types of parameters with each function definition.
956 * dbxread.c (define_symbol, function and parameter cases): Ditto.
957 (read_dbx_symtab, case N_DEFD): Ignore.
958 (read_enum_type): Recognize FALSE/TRUE enum as Modula-2 BOOLEAN.
959 (read_range_type): Rename MAX_OF_TYPE to MAX_OF_C_TYPE, etc.
960 #if 0 out its uses, though, since they set a dead value.
961 * coffread.c (end_symtab): Use allocate_symtab.
962 (process_coff_symbol): #if 0'd for functions and params as above.

1036 Tue Sep 17 08:37:41 1991 John Gilmore (gnu at cygint.cygnus.com)
1038 Add Andrew Beers' changes for Modula-2 support. His ChangeLog
1039 entries are enclosed herein. Not all of these changes
1040 have been merged into the master GDB sources -- check the
1041 ChangeLog above here for the merge log.
1043 Mon Jun 3 17:05:45 EDT 1991
1045 m2-exp.y Created. Tested outside of GDB for a few days. Proper
1046 operators were added, C specific operators and tokens
1047 removed. yylex() revamped to some extent. Still things
1048 missing from the grammar, such as sets.
1049 Tested for two weeks in GDB v3.5.
1051 Tue Jun 11 17:23:48 EDT 1991
1053 m2-exp.y Added boolean constants TRUE and FALSE to the grammar
1054 so they are built-in. Sort of a hack.
1056 Fri Jun 14 12:53:51 EDT 1991
1058 m2-exp.y Added range checking for numeric constants. Any numeric
1059 constant is assumed to be of builtin type INTEGER unless:
1060 (1) it is octal or hexadecimal, in which case it is a
1061 CARDINAL; (2) it is too big to fit into an INTEGER, in
1062 which case it is a CARDINAL.
1063 eval.c Added simple range checking for +, -, and * on integers.
1064 Doesn't work very well for *, since 6 * 1,000,000,000 =
1065 1,705,032,704, which fails the simple test of result >=
1066 first_operand, no matter in what order the operands are.
1068 Tue Jun 18 14:11:30 EDT 1991
1070 Broke the parser into parts, one containing the C grammar and the other
1071 containing code to be shared by all of the grammars.
1073 The following files no longer exist:
1078 The following files were added:
1080 c-exp.y (The C grammar)
1081 m2-exp.y (The Modula-2 grammar)
1082 parser-code.c (Code that is shared by the above grammar)
1086 Makefile.dist Changed to reflect the above dependencies. NOTE: It is
1087 now necessary to use the Bison compiler compiler, since it
1088 will generate function/variable prefixes other than yy.
1090 Tue Jun 18 16:47:49 EDT 1991
1092 symtab.[ch] Added the external variable working_lang, than holds the
1093 value of the current working language.
1094 Added the ennumerated type language_mode, with the values
1095 language_auto and language_manual, the former meaning that
1096 GDB sets working_lang as needed, and the latter meaning
1097 that the value of working_lang is totally under user
1099 symtab.[ch] Added the Modula-2 pervasive types INTEGER, CARDINAL,
1100 REAL, BOOLEAN and CHAR. Also added the type codes
1101 TYPE_CODE_BOOL and TYPE_CODE_CHAR.
1102 utils.c Added set_language_command and show_language_command to
1103 implement the GDB support commands "set language" and
1105 expression.h A number of identifiers were added to the type exp_opcode
1106 to facilitate Modula-2 builtin functions, integer
1107 division, and array indexing.
1109 Wed Jun 19 13:25:58 EDT 1991
1111 language.h Added the macro STRICT_TYPE, which evaluates to non-zero
1112 if the language specified by working_lang requires the use
1113 of strict typing of expressions. Eventually, even this
1114 will be able to be changed by the user.
1115 Added the macro RANGE_CHECK, which evaluates to non-zero
1116 if the language specified by working_lang requires the
1117 checking of a value against the domain of its type.
1118 Eventually, even this will be able to be changed by the
1120 language.[ch] Predicates involving types (simple_type, ordered_type,
1121 same_type, integral_type, numeric_type, character_type,
1122 boolean_type, float_type) are added. These predicates are
1123 based on the current value of working_lang, and are handy
1126 Wed Jun 19 15:39:34 EDT 1991
1128 eval.c Added the function type_array_rank which computes the rank
1130 valarith.c Added the funtion value_bool, which when given a integer
1131 value.h value (ie. struct value *) as an argument, it returns a
1132 boolean value (ie. struct value *) true if that integer
1133 is non-zero, and a boolean value false otherwise.
1134 valprint.c Added cases for TYPE_CODE_BOOL, so Modula-2 BOOLEAN values
1135 will print out properly.
1137 Wed Jun 19 16:36:34 EDT 1991
1139 valops.c Added the function value_capitalize, which returns it
1140 value.h argument capitalized if its argument is a lowercase
1141 letter, or the argument unchanged if its argument is not a
1143 valarith.c Added the function range_check_p, which returns non-zero
1144 value.h if its value argument is between the integral bounds upper
1146 Added the function range_check_enum_p, which makes sure
1147 that its value argument is a valid member of the domain of
1149 Added the function range_check_range_p, which makes sure
1150 its value argument lies between the upper and lower bounds
1151 of its type argument, which must be a ranged type.
1152 Added the function check_array_index, which range and type
1153 checks an index of an array.
1154 Added the function value_multi_subscript, which computes
1155 array[idx1,idx2...idxN], given a value array and an array
1156 of values representing indicies.
1157 values.c Changed value_from_long to work with TYPE_CODE_CHAR and
1158 unpack_long to work with TYPE_CODE_BOOL and
1161 Wed Jun 19 18:04:08 EDT 1991
1163 symtab.c Stored pervasive types in a structure and make
1164 lookup_pervasive_type() a lookup function that was based
1165 on working_lang. If lookup_pervasive_type() returned
1166 non-zero, then that value was returned (a fix, since
1167 before it simply wouldn't return the pervasive type.)
1168 language.h Added the macro CAST_IS_CONVERSION, which evaluates to
1169 non-zero if the language specified by working_lang means
1170 "conversion" when it says "cast".
1171 valops.c Added the function value_real_cast(), which performs a
1172 value.h *cast*, not a *conversion*, which is what value_cast()
1173 does when it can. In particular,
1174 value_cast(<float_type>,4) = 4.0, while
1175 value_real_cast(<float_type>,4) = some mess.
1176 eval.c Modula-2 builtin functions implemented: ABS, CAP, CHR,
1177 parser-code.c FLOAT, HIGH, MAX, MIN, ODD, ORD, TRUNC, and VAL.
1178 expression.h Added macros MAX_OF_TYPE and MIN_OF_TYPE to work with MAX
1179 and MIN on integral types. *NOTE*: These are currently
1180 hardcoded to work only if there are 8 bits per storage
1182 eval.c Made logical functions call value_bool to return a
1183 properly typed boolean value, based on working_lang.
1185 Thu Jun 20 11:55:27 EDT 1991
1187 valprint.c Types now print out in a Modula-2 fashion. This works for
1188 the cases when the type is printed out step-by-step, that
1189 is, it doesn't work when the name of a structured type
1190 (which includes the keyword "struct", etc.) is simply
1192 FIXME: Perhaps this is bad. Parts of it seem to kludgey,
1193 since type specifications in C and Modula-2 are very
1194 different. The C printing of a type is very recursive,
1195 whereas in Modula-2 it is generally very simple. C has
1196 type prefixes and suffixes, which have no real analogue in
1197 Modula-2. Maybe type_print() should call a language
1198 specific type printer. This is also advantageous if we
1199 compile GDB to exclude some of the languages. We'll just
1200 leave those functions out.
1202 Thu Jun 20 16:57:10 EDT 1991
1204 dbxread.c When reading the complete symbol table in (via
1205 psymtab_to_symtab()), the number and types of function
1206 arguments are added to a function type. define_symbol()
1207 calls add_param_to_type() to accomplish this.
1208 Assumption: when we come across a function definition
1209 (N_FUN symbol with an 'f' or 'F' in the name), its
1210 arguments will appear before another function definition.
1211 When a function is found, a pointer to its type is placed
1212 in the global in_function_type. Changes that
1213 add_param_to_type() makes are to this global.
1214 valprint.c The type of a function now includes (for Modula-2) the
1215 types of its parameters.
1216 eval.c Type checking and a check for the proper number of
1217 arguments is now done for function calls. Not sure of the
1218 impact this has on C++ member function yet.
1220 Thu Jun 20 19:58:48 EDT 1991
1222 valprint.c Rewrote the type printer. Broke it into two language
1223 specific parts, adding the functions type_print_m2() and
1225 An unfortunate consequence is this: if you debugging a C
1226 program in Modula-2 mode (why?), info types does not work
1227 well with regular expressions, since the types are printed
1228 out in Modula-2 terminology, but stored in C terminology.
1229 language.[ch] Added the functions new_type_last(), type_keyword(), and
1230 type_sep() to aid in the printing of typedefs.
1231 symtab.c Made the printing of typedefs as language independent as
1232 possible through calls to new_type_last(), type_keyword(),
1235 Fri Jun 21 11:50:26 EDT 1991
1237 dbxread.c Check all incoming ennumerated types. If it looks like
1238 Modula-2's BOOLEAN type, then change the type_code of the
1239 type to TYPE_CODE_BOOL so we can process it as a boolean
1241 valprint.c Replaced some of the 0x%x with calls to sprintf and
1242 hexformat() in val_print().
1243 language.[ch] Added the function hex_to_string(), which converts its
1244 integral argument to a hexadecimal number (format is
1245 language based) and returns the result as a string.
1247 Mon Jun 24 12:25:07 EDT 1991
1249 valprint.c Some functions call type_print_1() directly, instead of
1250 value.h using type_print(), so they can specify where (column) to
1251 print things. Since type_print() takes care of language
1252 dependence, that needs to be called first. Added a
1253 parameter depth to type_print() (so it is now like
1254 type_print_1). Changed type_print to type_print_at, and
1255 made type_print a macro that passes a depth argument of
1257 symmisc.c Changed all calls to type_print_1 to calls to
1259 Makefile.dist Made it possible to build GDB for a specific set of
1260 depend languages. Do this by passing a definition for the macro
1261 LANGS to make. LANGS should be a string containing a
1262 space-separated list of language names (ie. LANGS="c m2").
1263 The default is to build all languages. Note that grammar
1264 files must follow the naming convention of <lang>-exp.y.
1265 gdb.lang This holds the current value of the LANGS macro. It is
1266 examined every time make is called, and is updated if
1268 eval.c Added #ifdef _LANG_<lang> to these files.
1269 expread.c Still need to add them to dbxread.c and coffread.c.
1277 Mon Jun 24 16:33:11 EDT 1991
1279 language.[ch] Added the functions hexformat_pre() and
1280 hex_to_string_pre(), which take a prefix argument to
1281 include in the format string. Thus, hexformat_pre("08") will
1282 return "0x08x" (if the working language is language_c).
1283 Made hexformat() and hex_to_string() calls to the above
1284 with "" as the prefix argument.
1286 am29k-pinsn.c, arm-pinsn.c, breakpoint.c, convex-tdep.c, exec.c, core.c,
1287 dbxread.c, i386-pinsn.c, i386-stub.c, i386-xdep.c, i960-pinsn.c,
1288 infcmd.c, inflow.c, m68k-pinsn.c, m68k-stub.c, m88k-pinsn.c,
1289 mips-pinsn.c, mips-tdep.c, ns32k-pinsn.c, printcmd.c, pyr-pinsn.c,
1290 pyr-tdep.c, pyr-xdep.c, remote-vx.c, remote.c, solib.c, source.c,
1291 stack.c, sun386-xdep.c, symfile.c, symm-xdep.c, symmisc.c, tahoe-pinsn.c,
1292 valprint.c, vax-pinsn.c
1294 Changed all occurences of 0x%[0-9]*l*x in printf format strings to
1295 calls to hexformat() and hex_to_string(). Format strings without
1296 the leading "0x" were ignored.
1298 depend Updated to take the above into account.
1301 Tue Jun 25 15:27:18 EDT 1991
1303 symtab.h Added the types range_mode_t, range_check_t, type_mode_t,
1304 and type_check_t to keep track of the current state of
1305 range and type checking.
1306 main.c Added the variables range_mode, range_check, type_mode,
1307 and type_check to record the current state of range and
1308 type checking. Added initialization code to main().
1309 language.h Changed the macros STRICT_TYPE and RANGE_CHECK to examine
1310 the above variables.
1313 Tue Jun 25 17:57:08 EDT 1991
1315 dbxread.c process_one_symbol() updates the variable (enum language)
1316 source_lang based on the extension of the filename
1317 contained in the N_SO sybmol that started this symtab.
1318 When end_symtab() is called, the value of source_lang is
1319 put into the language field.
1320 stack.c select_frame() sets working_lang (and possibly type_check
1321 and range_check) to the language field of the symtab
1322 associated with the frame that is selected if working_mode
1323 is language_auto. If working_mode is language_manual, a
1324 warning is printed and working_lang is not set.
1325 language.c Added the function set_type_range(), which sets the value of
1326 type_check and range_check (if their modes call for
1327 automatic setting) based on the current value of
1328 working_lang. A non-zero argument will cause the current
1329 settings to be output.
1332 Wed Jun 26 14:51:40 EDT 1991
1334 eval.c Added range checks on assignment.
1335 m2-exp.y Added the grammar for sets to the language. Currently,
1336 these do not do anything except print an error message.
1338 Wed Jun 26 17:01:04 EDT 1991
1340 m2-exp.y Added the ability for parse_number() to parse negative
1341 numbers. A global flag is set upon encountering a unary
1342 minus. This was done to make, for example, 1 parse as a
1343 CARDINAL, and not as an integer, per Wirth's examples in
1344 Programming in Modula-2 ed.4.
1345 valprint.c Added support for "set radix 2" by then setting
1346 output_format to 't'.
1347 eval.c Implemented range checking on subrange types. Added calls
1348 to range_check_range_p for BINOP_ASSIGN and BINOP_VAL.
1349 Implemented MIN and MAX for ennumerated types. The
1350 minimum value of an ennumerated type is defined by Wirth
1351 as the first identifier, and the maximum as the last.
1352 m2-exp.y Made octal numbers ending with "B" be characters and those
1353 ending with "C" be numbers, per Wirth's book. (p. 34)
1355 Thu Jun 27 14:11:52 EDT 1991
1357 stack.c select_frame() now only sets working_lang, it does not
1358 notify the user. If working_mode is language_manual, then
1359 a warning is issued once.
1360 main.c At the end of each call to execute_command(), working_lang
1361 is checked against the local static (enum language)
1362 current. If they differ and working_mode is
1363 language_auto, the new settings of language, type and
1364 range checking are printed out.
1365 stack.c Modified frame_info() to include the language of the
1366 current frame in the output of "info frame".
1367 language.[ch] Added the function language_str() which returns the name
1368 of the current language.
1370 Fri Jun 28 15:33:14 EDT 1991
1372 m2-exp.y Added the built-in procedures INC, INCL, DEC, and DECL to
1373 the language. INCL and DECL currently cause an error,
1374 since sets are not implemented yet. INC and DEC are
1375 implemented as PREINCREMENT/PREDECREMENT with one
1376 argument, and as ASSIGN_MODIFY with two arguments.
1377 eval.c Added type checking to the above cases.
1378 value.h Added not_lval_constant to the lval_type ennumerated type.
1379 not_lval_constant means that the value is a constant
1380 value; that is 3 or 'a' or TRUE, not as in a constant
1381 identifier. This is used to help coerce numbers such as 3
1382 to either signed or unsigned numbers.
1383 valops.c Added the function value_coerce_constants() which coerces
1384 constant integers as following: if one is a constant and
1385 the other is not, the constant's type is set to the type
1386 of the other argument. If both are constants and one is
1387 signed, the other is converted to a signed constant.
1389 Sat Jun 29 17:26:29 EDT 1991
1391 valarith.c Added a better range checker. It now checks range
1392 (successfully) on integral operations [+-] (signed and
1393 unsigned) for any C sized type. Still does not work well
1394 for multiplication.)
1395 int_in_size() returns an integer that is coerced to fit into
1396 specified number of bytes.
1398 Mon Jul 1 13:04:14 EDT 1991
1400 language.[ch] Added the function binop_result_type(), which returns the
1401 builtin (struct type *) type that would be the result of a
1402 binop on the two values V1 and V2.
1404 Wed Jul 3 19:22:53 EDT 1991
1406 source.c Extended source_info() to include the source language in
1407 the output from "info source".
1409 Fri Jul 5 13:48:52 EDT 1991
1411 utils.c Moved the support functions for the GDB set/show commands
1412 dealing with language into language.c.
1413 language.c Added the function language_info(), which displays info
1414 about the current working language, type and range check
1415 settings. Called via the GDB command "info language".
1416 Added an initialization routine _initialize_language(),
1417 that sets defaults for the language, type and range
1418 variables and sets up the new GDB commands.
1419 main.c Language setup moved to language.c.
1422 Mon Jul 8 10:10:22 EDT 1991
1424 valarith.c Debugged the range checker for arithmetic. Still does not
1425 work for multiplication very well.
1427 Mon Jul 8 12:40:37 EDT 1991
1429 language.[ch] Added the function value_true() which returns non-zero if
1430 its argument represents a boolean true value.
1431 breakpoint.c Changed breakpoint_cond_eval() to call value_true() to
1432 check the truth of an expression.
1434 Thu Jul 11 12:51:34 EDT 1991
1436 language.[ch] Added the predicate structured_type(), which returns
1437 non-zero if the argument is a structured type.
1438 Added the predicate pointer_type(), which returns non-zero
1439 if the argument is a pointer type.
1440 eval.c Added the ability to do addition and substraction on
1441 pointers and integers. This case simply bypasses the
1444 Thu Jul 11 14:41:42 EDT 1991
1447 Added the symbol N_DEFD (0x4a) which is a definition
1448 module dependency that is used by the GNU Modula-2
1449 compiler and the linker. It is not important to GDB,
1450 except that [dbx|coff|mips]read.c should ignore these
1453 Fri Jul 12 16:07:00 EDT 1991
1455 valprint.c Changed the TYPE_LENGTH(type) >= 0 to TYPE_LENGTH(type) >
1456 0 in val_print(). Also added statements to the else part
1457 to coerce type (argument to val_print) to a pointer type
1458 if it is an "array of unspecified length".
1459 valops.c Added the function value_m2_string(), which returns a
1460 (value) value which is a constant string, whose type is
1461 (ARRAY [0..n] OF CHAR). The length field of the type
1462 structure is set to zero, so it will be interpreted as an
1463 "array of unspecified length".
1464 stack.c Moved the language/frame mismatch check to
1465 main.c:execute_command().
1466 main.c The working language is recorded each time
1467 execute_command() is executed. If working lang has
1468 changed during its execution, then the new
1469 language/type/range info is printed out for the user. If
1470 the working language does not match the language of the
1471 frame, a warning is issued.
1473 Sat Jul 13 16:16:39 EDT 1991
1475 eval.c Moved all the type-checking stuff for operators to
1476 language.[ch] language.c. This is so we can keep language-specific
1477 stuff (like for what type operators are defined) in
1479 language.[ch] Added the function binop_type_check(), which checks to see
1480 if its two (value) arguments are type-compatible with its
1481 opcode argument. The opcode should represent an operation
1482 involving an operator. Also added the macro function
1483 unop_type_check, which calls binop_type_check with a
1484 NULL second argument.
1485 expprint.c Added Modula-2 operators to the op_print_tab, so info
1486 expression.h break works correctly. Also added "op_string", which
1487 returns the string corresponding to the (enum exp_opcode)
1488 opcode that is its argument.
1491 Sat Jul 13 18:26:18 EDT 1991
1493 coffread.c Added code to record the type of function arguments with
1494 each paricular function. Code is very similar to that
1496 dbxread.c Moved add_param_to_type() to symtab.c
1497 symtab.[ch] Added function add_param_to_type() from dbxread.c
1499 *** NOTE: The above additions have not been tested.
1501 Mon Jul 15 12:50:47 EDT 1991
1503 langauge.[ch] Added the functions type_error and range_error, which work
1504 like error() except if the type/range mode is set to
1505 *_mode_warn, then they do not do a return_to_top_level(),
1506 but merely print a warning.
1507 Also changed [set|show]_[type|range]_command() to support
1508 the new "warn" feature.
1510 Thu Jul 18 17:50:54 EDT 1991
1512 mipsread.c Added code to record the type of function arguments with
1513 each particular function. Code is very similar to that
1516 *** NOTE: The above additions have not been tested.
1518 Fri Jul 19 11:19:10 EDT 1991
1520 defs.h Added macros MAX_OF_SIZE, MIN_OF_SIZE, UMAX_OF_SIZE, and
1521 UMIN_OF_SIZE, which when given a size of a numeric type,
1522 return the maximum and minimum value it can hold. UMAX...
1523 and UMIN... return the result for unsigned types.
1524 symtab.h Added the macros MAX_OF_TYPE and MIN_OF_TYPE to operate on
1525 struct types. They call above macros.
1526 dbxread.c Renamed the MAX and MIN_OF_TYPE macros to ..._OF_CTYPE to
1527 avoid a name conlict with the above.
1528 c-exp.y Added range checking on numeric constants in
1529 parse_number() for completeness.
1530 valarith.c Made binop_user_defined_p() and unop_user_defined_p()
1531 return 0 if working_lang is not language_c.
1533 Thu Aug 8 14:17:22 EDT 1991
1537 breakpoint.c Documentation strings of some commands changed to
1538 eliminate the references to the C language where
1541 Tue Aug 13 15:48:03 EDT 1991
1543 m2-exp.y Added qualified identifiers to the grammar. The semantics
1544 are slightly different from those of the GDB operator ::
1546 m2-exp.y Added a rule to each grammar of the form: start ::= exp |
1547 type_exp, where type_exp is any valid type expression.
1549 eval.c Added the opcode OP_TYPE, and an error case in eval.c.
1550 printcmd.c Modified ptype_command() so it actually parses the input
1551 (necessary for type expressions with scope qualifiers).
1552 Added the function ptype_eval() which expects an
1553 expression composed of one OP_TYPE element.
1554 *.[ch] Replaced all occurences of parse_c_expression with
1556 *.[ch] Replaced all occurences of parse_c_1 with parse_exp_1
1558 [End of ChangeLog entries from Andrew Beers for Modula-2 support.]
1560 Mon Sep 16 17:19:46 1991 John Gilmore (gnu at cygnus.com)
1562 Small fixes from Peter Schauer:
1564 * infrun.c (child_attach): Lint.
1565 * solib.c (find_solib): Handle shared libs version 2.
1567 Small fixes from David Wood:
1569 * xm-ultra3.h (SYS_SIGLIST_MISSING): Typo.
1573 * remote-vx.c: Move <stdio.h> to top, for FILE. Fix from
1574 John S <basrai%kanga.dnet@c3po.sm-alc.af.mil>.
1576 * utils.c (wrap_here): Avoid wrap action of fputs_filtered if
1577 chars_per_line is at maximum (user typed `set width 0'). Fix
1578 from Andreas Schwab <schwab@ls5.informatik.uni-dortmund.de>.
1580 Tue Sep 17 17:31:04 1991 Stu Grossman (grossman at cygnus.com)
1582 * coredep.c: include ptrace.h where necessary.
1583 * mipsread.c(parse_lines): fix unsigned char problem that was
1584 messing up line numbers on SGI's and possibly other MIPS based
1586 * infrun.c (child_create_inferior): use better test to check
1587 return val from setpgrp().
1588 * tm-irix3.h, xm-irix3.h, tconfig/irix3, xconfig/irix3: add these
1589 for sgi/irix support.
1591 Wed Sep 18 04:33:31 1991 Per Bothner (bothner at cygnus.com)
1593 * mipsread.c (parse_symbol): Put non-static procedures
1594 in the global block.
1596 Fri Sep 13 00:14:52 1991 John Gilmore (gnu at cygnus.com)
1598 Patch together `text_start' and `text_end' for 29K port.
1600 * exec.c (exec_command): If NEED_TEXT_START_END, define the
1601 variables and set them based on the exec file.
1602 * am29k-tdep.c: declare text_start.
1603 * valops.c (call_function_by_hand): declare text_end.
1605 * inferior.h: Eliminate CANNOT_EXECUTE_STACK in favor of
1606 defining CALL_DUMMY_LOCATION as BEFORE_TEXT_END. This is
1607 because machines that do this will also have to know to
1608 set NEED_TEXT_START_END. Besides, it was a redundant way to
1610 * tm-29k.h, tm-convex.h, tm-np1.h: Eliminate
1611 CANNOT_EXECUTE_STACK, define CALL_DUMMY_LOCATION and
1612 NEED_TEXT_START_END.
1614 Thu Sep 12 00:22:24 1991 John Gilmore (gnu at cygint.cygnus.com)
1616 AMD 29000 changes from David Wood <wood@david.ultra.nyu.edu>:
1618 * Makefile.in (CLIBS): Put XM_CLIBS and TM_CLIBS at end.
1619 Pass MUNCH_DEFINE to munch whenever we run it.
1620 * am29k-pinsn.c (print_insn): Handle NOP specially. Avoid %#x
1621 format string; use 0x%x instead.
1622 * am29k-tdep.c: Use DUMMY_SAVE_GREGS and RETURN_REGNUM.
1623 * ultra-xdep.c, xm-ultra.h: New files for Ultracomputer host system.
1624 * xm-rtbsd.h: New host support for RT/PC running BSD Unix.
1625 * inflow.c: Handle `short' process group IDs.
1626 * infptrace.c (fetch_register): Support CANNOT_FETCH_REGISTER,
1627 and check for ptrace errors.
1628 * coffread.c (SDB_REG_TO_REGNUM): Define if not already.
1629 (coff_symfile_init): Initialize text_bfd_scnum.
1630 (read_coff_symtab): Use it to find the text [and absolute?] sections.
1631 * ../config.sub: Add vendor nyu and os "sym[1-9]*".
1632 * configure.in: Add hosts rtpc-*-* and a29k-*-*.
1633 Merge target arm case with other "easy" cases. Add target
1634 cases a29k-*-none (rehack of am29k), a29k-*-kern (remote to
1635 Ultracomputer kernel), and a29k-*-sym1 (ultracomputer OS's user
1637 * minimon.h, remote-adapt.c, remote-mm.c: Add.
1638 * munch: Cope with RT/PC putting fns in data segment.
1639 Restore ability to override `nm' by specifying MUNCH_NM.
1640 * xconfig/rtbsd, xconfig/ultra3: New host systems.
1641 * tconfig/a29k: Rename from tconfig/am29k. Add remote-mm
1642 and remote-adapt. Remove encapsulated coff #define's (the
1643 support should go in BFD, and gdb shouldn't know or care).
1644 * tconfig/a29k-kern: Same, but for remote kernel debugging.
1645 * tconfig/ultra3: For debugging user processes on Ultra3/Sym1.
1646 * tm-29k.h: Update BADMAG (though it should go away).
1647 Allow the register definitions to be overridden in another
1648 tm-file. Fix SR_REGNUM. Add a mess of _REGNUM's. Separate
1649 RETURN_REGNUM from GR96_REGNUM and DUMMY_SAVE_GREGS from
1650 DUMMY_SAVE_GR96, for handling kernel calling conventions
1651 that use GR64+ rather than GR96+.
1652 * tm-ultra3.h: New file, for use on Ultra3 Unix as well as for
1653 remote debugging of Ultra3 kernel. Includes tm-29k.h and
1654 overrides various things.
1656 * remote-mm.c (mm_attach, mm_wait): Handle attach like
1657 child_attach does, making a clean stop in the newly attached
1659 * remote-eb.c: Lint.
1661 * coffread.c: Make coffread independent of any particular
1662 variant of COFF. Avoid #include-ing any particular one except
1663 internalcoff.h. BFD now passes key values for symbol reading
1664 as part of its coff_data structure (LINESZ, SYMESZ, AUXESZ,
1665 and the symbol masks and shifts); use them.
1666 Remove obsolete end_of_text_addr.
1668 * exec.c: Remove unused include files.
1670 Wed Sep 11 19:38:44 1991 John Gilmore (gnu at cygint.cygnus.com)
1672 * Makefile.in (documentation targets): Pass $(M4).
1673 Bugfix from eggert@twinsun.com (Paul Eggert).
1675 * stack.c (down_silently_command): Check for stack existence.
1677 Tue Sep 10 23:08:29 1991 John Gilmore (gnu at cygint.cygnus.com)
1679 * Makefile.in (VERSION): Update to 4.0.3.
1681 Tue Sep 10 09:19:29 1991 John Gilmore (gnu at cygint.cygnus.com)
1683 * core.c (core_file_command): Print frame at coredump with
1684 its level number, by calling print_stack_frame.
1685 * frame.h: Add selected_frame_level, print_stack_frame.
1686 * frame.h, stack.c: Remove print_sel_frame, print_selected_frame.
1687 * convex-tdep.c, convex-xdep.c, infcmd.c, inflow.c, infrun.c:
1688 Change print_sel_frame and print_selected_frame callers to
1691 * dbxread.c (read_ofile_symtab): Avoid empty else clause.
1692 * symfile.c (free_named_symtabs): Ditto.
1693 * main.c (main): wrap_here needs an arg.
1694 * solib.c (find_solib): Avoid memory access if _DYNAMIC is zero.
1695 (solib_add): Avoid noise.
1696 (solib_create_inferior_hook): Lint.
1697 (sharedlibrary_command): Move dont_repeat to here.
1698 * utils.c (error): Call wrap_here to force buffered output.
1700 Small patches from Peter Schauer:
1702 * coffread.c (start_symtab): Free any existing line_vector before
1704 (read_coff_symtab): Ditto for type_vector.
1706 * source.c (lines_to_list): New variable, replacing function.
1707 (all uses): Use as variable.
1708 (_initialize_source): Add 'set listsize' and 'show listsize'.
1709 * utils.c (lines_to_list): Remove function.
1710 * stack.c (print_frame_info): Use as variable.
1711 * defs.h (lines_to_list): Remove declaration.
1713 Mon Sep 9 13:45:57 1991 John Gilmore (gnu at cygint.cygnus.com)
1715 * breakpoint.c (insert_breakpoints): Restore warning about
1716 the program might be running in another process, but only for
1717 systems with this brain death (#ifdef ONE_PROCESS_WRITETEXT).
1718 * xm-hp300bsd.h, xm-mips.h, xm-vax.h: Define it.
1720 * utils.c (error): if error_pre_print is set, print the string
1722 * main.c (main, print_gnu_advertisement, print_gdb_version):
1723 Reformat legalese so it always prints, but acts as an "I'm here"
1724 message while symbols are being read. If any errors occur,
1725 print a few newlines to set off the message and start it at the
1726 left margin. Remove mention of "help" command, and don't yak
1727 about symbol reading.
1728 (catch_errors): Error string is now printed first in case of
1730 * command.c (undef_cmd_error, lookup_cmd): On undefined command,
1731 suggest the "help" command.
1733 * Makefile.in (VERSION): Set to 4.0.2.
1735 Thu Sep 5 23:49:48 1991 John Gilmore (gnu at cygint.cygnus.com)
1737 * .gdbinit: Remove useless "rr" command. Set complaints
1738 to 1 for people debugging gdb.
1740 * breakpoint.c, remote-vx.c: Reword strings printed by
1741 catch_errors callers.
1743 Wed Sep 4 11:07:50 1991 John Gilmore (gnu at cygint.cygnus.com)
1745 * WHATS.NEW: "history write -> history save". Doc "write on/off".
1746 (Fix from kenc@viewlogic.com.)
1748 Fix some infrastructure to be able to cope with host and target
1749 machines with different sized basic types (ints, ptrs, etc).
1750 (Idea from pierre@la.tce.com (Pierre Willard).)
1752 * values.c (value_from_longest): Rename from value_from_long.
1753 Handle pointer types as well as integers, so that targets with
1754 different pointer sizes from the host can be accomodated.
1755 * breakpoint.c, convex-tdep.c, eval.c, expprint.c, printcmd.c,
1756 valarith.c, valops.c, valprint.c, value.h, values.c: Rename
1757 uses of value_from_long to value_from_longest.
1758 * eval.c, findvar.c, printcmd.c, valarith.c, valops.c: Pass
1759 the correct pointer type to value_from_long{est}.
1761 * doc/gdb.texinfo ($_, $__): Describe types of these variables.
1763 * remote-vx.c: Remove obsolete code for calling functions via
1764 vxworks kludge interface (it referenced value_from_long).
1766 * valops.c (value_string): Find malloc with lookup_misc_func, not
1769 Tue Sep 3 18:37:46 1991 John Gilmore (gnu at cygint.cygnus.com)
1771 Make writing to files work properly. (Fixes to BFD are also needed.)
1773 * core.c (core_open): Open file ourselves, read or r/w, depending on
1774 write_files. Use bfd_fdopenr.
1775 * gdbcore.h (write_files): New variable.
1776 * exec.c (write_files): Define variable, add set&show for it.
1777 (exec_file_command): Use write_files to open for read or r/write.
1779 Make shared library reading happen automatically. These changes
1780 are mostly from Peter Schauer <pes@regent.e-technik.tu-muenchen.de>.
1782 * inferior.h (stop_soon_quietly): Add to exported variables.
1783 * infrun.c (child_create_inferior): call solib hook, if defined.
1784 (child_attach): call solib hook, if defined.
1785 * solib.c: Include inferior.h. Add from_tty to so_list as kludge.
1786 (find_solib): Use lookup_misc_func rather than hand-rolled.
1787 (symbol_add_stub): New stub for catch_errors.
1788 (solib_add): Avoid output if !from_tty. Catch errors rather
1789 than just calling symbol_file_add and bombing.
1790 (solib_create_inferior_hook): Interface with the target process
1791 to let it read and alloc shared libs, then figure out what it did.
1793 * core.c (validate_files): Fix typo, soften warning.
1794 (Fix from Hiroto Kagotani <kagotani@cs.titech.ac.jp>.)
1796 * utils.c (fputs_demangled): Avoid duplicate printing if
1797 demangling is off. (Fix from J.T. Conklin <jtc@cayenne.com>.)
1799 * infrun.c (proceed): Cast -1 to (CORE_ADDR) before comparing.
1800 (Fix from pierre@la.tce.com (Pierre Willard).)
1802 * main.c (catch_errors): Change argument to a char * from an int,
1803 since a char * can point to a struct full of glop, but an int
1804 is not guaranteed to be able to hold a pointer.
1805 * breakpoint.c (breakpoint_cond_eval, bpstat_stop_status,
1806 breakpoint_re_set_one, breakpoint_re_set): Adapt.
1807 * core.c (core_open, solib_add_stub): Adapt.
1808 * remote-vx.c (symbol_stub, add_symbol_stub, callers): Adapt.
1810 Wed Aug 28 18:18:05 1991 John Gilmore (gnu at cygint.cygnus.com)
1812 * Makefile.in: Update VERSION to 4.0.1. Evade GNU Make bug
1813 by adding .NOEXPORT target.
1815 Fri Aug 23 17:14:25 1991 John Gilmore (gnu at cygint.cygnus.com)
1819 * Makefile.in (VERSION): Roll to 4.0.
1820 (gdb.tar.Z): Make refcard.ps as well, for shipment.
1822 Fri Aug 23 14:07:09 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1824 * doc/gdb.texinfo: minor rewordings, crossref to ptype from print,
1827 * doc/Makefile, Makefile.in: generate "gdb-all.texi" rather than
1830 * doc/rdl-apps.texi: renamed from rdl-apps.texinfo
1832 * Makefile.in, doc/Makefile, doc/.Sanitize, doc/gdb.texinfo:
1833 reflect above name change
1835 * WHATS.NEW: correct pointer to refcard.
1837 * doc/gdb.texinfo: update New Features, Installing
1839 * doc/gdbint.texinfo: add short description of configure +template
1841 Fri Aug 23 11:46:08 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1843 * doc/gdb.texinfo: update, fix bugs in "Installing" appendix
1845 Fri Aug 23 01:02:00 1991 John Gilmore (gnu at cygint.cygnus.com)
1847 * Makefile.in: Add config.sub, make doc/rdl-apps.texinfo for
1848 tar file, add dependencies for referenced doc files.
1850 Thu Aug 22 22:17:06 1991 Stu Grossman (grossman at cygint.cygnus.com)
1852 * coffread.c, symfile.c, stack.c: saberized.
1854 Thu Aug 22 16:20:27 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1856 * doc/refcard.tex: permuted Essential Commands sec
1858 * doc/gdb.texinfo: new C++ chapter; revised installation appendix;
1860 set/show symbol-reloading
1861 default set complaints 0
1863 RET-repeat disabled after prompted long displays
1864 processID (attach) interpretation of 2nd GDB cmdline arg
1866 Thu Aug 22 14:05:47 1991 Stu Grossman (grossman at cygint.cygnus.com)
1868 * expread.y, coffread.c, dbxread.c, target.c, mem-break.c,
1869 cplus-dem.c, values.c, valprint.c, symfile.c, remote.c,
1870 breakpoint.c, main.c: lint.
1872 Thu Aug 22 02:02:26 1991 John Gilmore (gnu at cygint.cygnus.com)
1874 Install new configuration scheme for GDB and friends.
1876 * config.sub: Translate ordinary names to three-part names.
1877 * configure: Use three-part names internally.
1878 * configure.in: Translate three-part names to filenames.
1880 * README, WHATS.NEW: Update for gdb-4.0.
1881 * Makefile.in: Roll VERSION to 3.99.
1883 Wed Aug 21 18:21:09 1991 John Gilmore (gnu at cygint.cygnus.com)
1885 * infptrace.c (KERNEL_U_ADDR_BSD): Include a.out.gnu.h.
1886 * i960-tdep.c, m68k-tdep.c, sparc-tdep.c, tm-i960.h,
1887 tm-m68k.h, remote-nindy.c: Change ext_format_XXX structs
1888 to single structures rather than arrays; when passing
1889 their address, use &. This avoids trouble with bdead compilers.
1890 * mcheck.c: Don't include <stdlib.h>; just declare "void abort();"
1891 instead. This avoids portability headaches.
1892 * mips-tdep.c (mips_do_registers_info): Only print FP regs if
1894 * source.c (open_source_file): Avoid ANSI const bdeath by
1895 skipping declaration and then casting result value.
1896 * tm-hp300bsd.h: Clarify comment.
1897 * utils.c (strstr): Result is const char *; ANSI bdeath.
1898 * xm-hp300bsd.h: Define HOST_BYTE_ORDER. Redefine INT_MIN,
1899 since system include file defines it differently from "defs.h",
1900 though the two are equivalent for our purposes.
1901 * tconfig/hp300bsd: Add m68k-tdep.o.
1903 Tue Aug 20 16:01:11 1991 John Gilmore (gnu at cygint.cygnus.com)
1905 * tconfig/sun*4: Remove warnings about system assembler.
1907 Mon Aug 19 13:44:46 1991 John Gilmore (gnu at cygint.cygnus.com)
1909 * mcheck.c: Avoid warning about undeclared abort fn.
1910 * tm-sparc.h (PC_ADJUST): Avoid calling error() from this;
1911 it causes recursive calls to error() when used in cleanups.
1912 To do so requires that we make it a function, so we do.
1913 * sparc-tdep.c (sparc_pc_adjust): New implem of PC_ADJUST.
1914 * utils.c (do_cleanups): Remove the current cleanup from the
1915 chain *before* calling it, in case error() is called from it.
1916 The result won't be pretty, but won't be an infinite loop either.
1918 Mon Aug 19 00:41:04 1991 Michael Tiemann (tiemann at cygint.cygnus.com)
1920 * dbxread.c (read_struct_type): Grok anon structs for C++.
1921 (vb_name, vptr_name): Null terminate these strings.
1923 Fri Aug 16 08:31:03 1991 John Gilmore (gnu at cygint.cygnus.com)
1925 Minor bug fixes from BSD Net2 gdb:
1927 * blockframe.c (get_prev_frame_info): If FRAME_CHAIN_COMBINE
1928 returns 0, there is no previous frame.
1929 * breakpoint.c (commands_command): If !from_tty, don't call
1930 input_from_terminal_p().
1931 * dbxread.c (record_misc_function): Speed up slightly.
1932 (compare_psymbols): Ditto.
1933 * infcmd.c (do_registers_info): Take a second argument to
1934 determine whether to print float registers. "info registers"
1935 does not do so anymore. "info all-registers" does, now.
1936 * mips-tdep.c, pyr-tdep.c (xxx_do_registers_info): Take second
1938 * tm-mips.h, tm-pyr.h (DO_REGISTERS_INFO): Pass second arg.
1939 * inflow.c (initialize_inflow): Set tflags_ours correctly.
1943 * breakpoint.c (bpstat_do_actions): Use a cleanup to restore
1944 executing_breakpoint_commands if we are interrupted by error.
1945 * coffread.c (init_lineno): Avoid problem with zero-sized linetab
1946 versus malloc/free. From: john@labtam.labtam.oz.au (John Carey).
1947 * core.c (solib_add_stub, core_open): Call SOLIB_ADD inside a
1948 catch_errors() so we can setup the frame regardless of whether
1949 the shared libs work.
1950 * ieee-float.c (double_to_ieee_extended): Get exponent from
1951 right place in little-endian systems. From John Carey.
1953 Thu Aug 15 18:43:57 1991 John Gilmore (gnu at cygint.cygnus.com)
1955 * main.c: Remove unused terminating_signals and catch_termination().
1956 (long_options): Terminate with a zero element.
1957 [Bugfix from Atsuo Kawaguchi <atsuo@hark86.harl.hitachi.co.jp>.]
1958 (gdb_readline): Make call-compatible with readline.
1959 (init_signals): Improve comments re vfork vs. signal.
1961 * utils.c (prompt_for_continue): Use new gdb_readline().
1962 If we prompt for continuation, we don't let CR repeat the previous
1963 command, once we get back to a prompt. It's too easy to keep
1964 hitting CR, expecting "--more--" prompts, and have some long
1965 command start repeating on you.
1967 Tue Aug 13 16:17:56 1991 John Gilmore (gnu at cygint.cygnus.com)
1969 * blockframe.c (frameless_look_for_prologue): Speed up by
1970 calling SKIP_PROLOGUE_FRAMELESS_P if it's defined.
1971 * tm-sparc.h (SKIP_PROLOGUE, SKIP_PROLOGUE_FRAMELESS_P):
1972 Define two variants, one faster.
1973 * sparc-tdep.c (sparc_frame_chain): Use target_read_memory
1974 and return zero, rather than giving an error.
1975 (setup_arbitrary_frame): Initialize the PC in the new frame.
1976 (skip_prologue): Add a second arg saying whether we're just
1977 checking for a frameless function or not.
1979 * core.c (core_open, core_close, core_xfer_memory): Move
1980 section table pointers and bfd* into the target_ops.
1981 (core_open): Allow errors in shared lib reading, etc.
1982 (core_files_info): Describe shared library sections.
1984 * exec.c (exec_open, exec_close, exec_xfer_memory, xfer_memory,
1985 exec_files_info, set_section_command): Move section table
1986 pointers and bfd* into the target_ops.
1987 (add_to_section_table): Add BFD to section table.
1989 * target.c (target_xfer_memory, target_info): Pass target to
1990 xfer_memory and target_info functions.
1993 * gdbcore.h: Move struct section_table.
1994 * target.h: New home of struct section_table.
1996 * solib.c (solib_add): New argument is the target_ops whose
1997 section list is to be added to, if any. Reallocate the
1998 sections in that target to add any that come from shared libs.
1999 (throughout) so_sections renamed to sections.
2000 (solib_xfer_memory): Deleted.
2001 * tm-sunos.h (SOLIB_ADD): Add target argument.
2002 (SOLIB_XFER_MEMORY): Delete.
2004 * core.c, exec.c, inftarg.c, remote-eb.c, remote-nindy.c,
2005 remote-vx.c, remote.c, target.c, target.h: Remove add_syms vector
2006 from target_ops. It's the same on all targets. Add two section
2007 pointers to target_ops.
2009 * stack.c (find_relative_frame): Dump ancient algorithm for
2010 "down", just use handy "next" pointers.
2011 (frame_command): Don't error if there is no stack; let user
2014 * inflow.c (new_tty_prefork, new_tty): New prefork routine
2015 modifies static state in the parent process; new_tty itself
2016 runs in the child and modifies the child's file descriptors
2017 to match the saved static state.
2018 * infrun.c (child_create_inferior): Call new_tty_prefork,
2021 * infptrace.c (child_xfer_memory): Add ignored target arg.
2022 * remote-eb.c (eb_xfer_inferior_memory): ''
2023 * remote-nindy.c (nindy_xfer_inferior_memory): ''
2024 * remote-vx.c (vx_xfer_memory): ''
2025 * remote.c (remote_xfer_memory): ''. Rename from
2026 remote_xfer_inferior_memory.
2028 * main.c (main): Only try to attach "corefile" argument if
2029 it starts with a digit.
2031 * symfile.c (symbol_reloading): New "set/show" variable.
2032 (symbol_file_add): Shorten message about symbol reading.
2033 (add_symbol_file_command): Merge with add_syms_addr_command,
2034 since this should work on all targets now.
2035 (stop_whining): Default to zero, to shut up complaints
2036 about bad symbol tables on many systems.
2037 (free_named_symtabs): Just exit unless symbol_reloading.
2039 * xm-sun3os4.h, xm-sun4os4.h: Define BROKEN_LARGE_ALLOCA,
2040 and add comment explaining shared library screw.
2042 * source.c: #if defined => #ifdef.
2044 Thu Aug 8 12:23:19 1991 John Gilmore (gnu at cygint.cygnus.com)
2046 * doc/gdbint.texinfo: Improve doc on porting to new OS's.
2048 Tue Aug 6 17:16:15 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
2050 * doc/rdl-apps.texinfo: provide default readline-appendix finder
2051 (doc/Makefile knows how to make one for local config)
2053 * Makefile.in: use doc/Makefile for doc targets
2055 * doc/Makefile: GDB documentation now has its own Makefile
2056 doc/refcard.tex: renamed from "gdbrc.tex"
2057 doc/.Sanitize: add Makefile; recognize renamed refcard.tex
2058 doc/gdbint.texinfo: add markup in "Cleanups" chapter
2061 Fri Aug 2 00:13:06 1991 John Gilmore (gnu at cygint.cygnus.com)
2063 * values.c (baseclass_addr): When reading target memory, use the
2064 length of the basetype, not the upper type. We've only malloc'd
2065 enough space for the basetype, leading to errors in free().
2067 * expprint.c (print_subexp): Print UNOP_MEMVAL of an OP_LONG that
2068 ends up as a function specially, since we know the actual type of
2069 the pointed-to address. This (somewhat) fixes display of
2070 expressions that include misc_function_vector names. Try `cond 1
2071 !strcmp("a","b")' then `i b'.
2073 * infrun.c: Move DO_DEFERRED_STORES from proceed() to resume().
2074 The child can be proceeded from inside wait_for_inferior in
2075 evaluating breakpoint conditions, and DO_DEFERRED_STORES was
2076 getting skipped in that case.
2078 * expprint.c (print_subexp): Use filtered output, since the
2079 subroutines we call use it, otherwise the output is horribly
2080 mangled, since output of wrappable stuff comes out late.
2082 * Makefile.in: Bump VERSION to 3.98.1
2084 * infrun.c (child_create_process): Use execlp to find the
2085 shell to exec our target program. This requires some fiddling
2086 with `environ' since there is no execlpe().
2088 Thu Aug 1 15:35:17 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
2090 * Makefile.in, doc/gdbrc.tex, doc/rc-* (new files):
2091 Minor rearrangement of refcard permits two new make targets--
2092 gdbrc.dvi DVI output for refcard, using CM fonts
2093 gdbrc.ps PostScript refcard, using PS fonts
2095 Wed Jul 31 16:46:21 1991 John Gilmore (gnu at cygint.cygnus.com)
2099 * TODO, Projects, WHATS.NEW, README: Update for gdb-3.98.
2100 * Makefile.in (gdb-all.texinfo): Avoid touching file if M4 dies.
2102 Wed Jul 31 16:35:58 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
2104 * doc/gdb.texinfo: last changes for release.
2105 Minor typo and formatting fixes; incorporated most fixes remaining from
2106 filed mail commenting on earlier drafts.
2108 Added warnings: pipes don't work in run command;
2109 conditions are converse of assertions;
2110 step over fn without debug info goes to next fn;
2111 vars may have "wrong" values near fn entrance, exit
2113 Added example from Kingston on printing repeated nonadjacent values
2115 Added explicit mention that in Emacs gdb mode C-c and C-z are like
2116 shell mode for signals
2118 Renamed "Stepping and Continuing" to "Continuing and Stepping" so it
2119 doesn't sound so much like its parent "Stopping and Continuing"; also
2120 moved entries on continue to top of section, so they don't get lost.
2122 Improved installation directions in appendix, added manual formatting
2125 Tue Jul 30 17:26:39 1991 John Gilmore (gnu at cygint.cygnus.com)
2127 * configure.in: Remove xm.h and tm.h even if we aren't linking
2128 new ones, so "./configure sun4; ./configure none" does the right
2129 thing. Assume that alldeps.mak and depend are already built in
2130 srcdir, and avoid running "make" (particularly "make depend",
2131 which involves "gcc") from inside configure. Build Makefile
2132 directly rather than building Makefile.conf first.
2133 * configure: Regenerate with above changes.
2134 * Makefile.in: Use $(BISON) to find bison. Roll VERSION
2135 to 3.98. Revise gdb.tar.Z procedure to produce a file
2136 called gdb-$(VERSION).tar.Z but which unpacks into a
2137 directory called "gdb". Move non-source files out of
2138 $(SFILES_SUBDIR). Pretty up alldeps.mak with comments.
2139 (depend): Don't try to do "gcc expread.y".
2140 (expread.o): Update dependencies by hand.
2142 Mon Jul 29 15:21:09 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
2145 Fixed a variety of small typos that prevented info from formatting
2146 cleanly; altered too-long heading for GPL Appendix, as discussed
2147 w/RMS; Changed date on cover to July 91.
2149 Fri Jul 26 13:20:02 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
2152 (1) Applied some fixes due to comments from Larry Breed (easier ones
2153 through chapsec 5.2)
2154 (2) Eliminated use of @footnote---had my doubts about it anyways, and
2155 it's broken in latest texinfo
2156 (3) Introduced *some* use of [] for optional arguments, where
2157 explanation is not simpler by listing cmd w arg and cmd w/out arg
2158 separately. Still not using @deffn.
2159 (4) Dropped in GPL-2. NOTE: one of GPL-2 or texinfo is broken; a
2160 couple of headings are too long. Need patches to texinfo or revision
2163 * Partial update to README (which still needs work for this
2164 release!): (1) use of configure corrected for new script,
2165 (2) "make gdb.dvi" and "make gdb.info" mentioned.
2167 Wed Jul 24 06:44:02 1991 John Gilmore (gnu at cygint.cygnus.com)
2169 * symtab.c (lookup_symbol): Don't complain right off about
2170 no debug symbols; use the misc function vector first.
2171 (list_symbols): Use misc function vector to find symbols
2172 that don't have debug info, and print them.
2173 (find_pc_symtab): Temporarily avoid fatal() when psymtab
2174 PC range doesn't match symtab PC range, as it does on the
2175 MIPS because our symtab reading isn't perfect.
2177 * dbxread.c (dbx_symfile_read): Make warning about
2178 "no debug symbols" slightly nicer.
2180 * source.c (select_source_symtab): If "main" symbol exists,
2181 but decode_line_spec can't find line info, don't just return
2182 a zero; try other source symtabs or give an error.
2184 * mipsread.c (parse_partial_symbols): Sort the psymtabs by
2185 their low addresses first, then rip through fixing high addrs.
2187 * ns32k-opcode.h (sfsr): Bugfix from Rune Nerg}rd,
2188 <runene@ifi.uio.no>.
2189 (NS32K_SVC_IMMED_OPERANDS): Reverse the #ifndef.
2191 Tue Jul 23 18:52:43 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
2193 * Minor, mostly mechanical, cleanup of doc subdir for clean
2194 makeinfo'ing and TeXing; also ensured gdb-all.texinfo (post-m4)
2195 and gdb.info (post- texinfo2 makeinfo) generated for distribution.
2197 Sun Jul 21 03:54:52 1991 John Gilmore (gnu at cygint.cygnus.com)
2199 Mostly MIPS and general symbol-reading fixups.
2201 * doc/gdbint.texinfo: Add documentation on symbol-reading
2204 * mipsread.c: Remove kludges around #include "ecoff.h".
2205 Remove redefinitions of a_magic, etc, no longer used.
2206 (parse_symbol, ): Convert "Internal:" printfs to complain()ts.
2207 Fix global overview comments to match symfile.c protocol.
2208 (mipscoff_new_init): Eliminate cur_hdr if we have one.
2209 (mipscoff_symfile_read): Eliminate unused code. Avoid
2210 sorting all the symtabs, when all we have read here is psymtabs.
2211 The symtabs are sorted as they are created anyway. Tell
2212 condense_misc_bunches whether we're mainline.
2213 (psymtab_to_symtab_1): Pass filename when recursing, to make
2214 stack trace more informative.
2215 (parse_partial_symbols): Assume cur_hdr as argument.
2216 (read_mips_symtab): Don't clobber cur_hdr, so it can be freed.
2217 Pass cur_hdr implicitly to parse_partial_symbols. Avoid checking
2218 the TYPE_NAME of char *, since that's done in symfile.c.
2219 (free_numargs, parse_symbol, add_symbol, add_block,
2220 shrink_linetable): Declare these fns void.
2221 (upgrade_type): Convert tree of if's to switch. Clean up
2222 bogus "off == 0" handling with a complaint. Avoid setting
2223 field bitpos and bitsize of array with lower and upper bounds.
2224 Check specified bitsize of elements against their actual type's
2225 bitsize, and complain if different. Complain about unknown
2227 (parse_fdr): Don't assume sizeof(char *) == sizeof (struct *).
2228 (psymtab_to_symtab_1): Print names of subsidiary files that
2229 are being read in. FIXME, we read far too many files. This code
2230 is not the problem, the problem is in parse_fdr where the psymtabs
2232 (cross_ref): Result should indicate that we used one aux entry
2233 normally, or two if we encountered a "next" entry. This used
2234 to leave the caller pointing at the wrong aux entry.
2235 (add_symbol): If overflowed cur_block, reallocate it larger,
2236 chase all pointers to it, and complain(), rather than clobber memory.
2237 (shrink_block): Use xrealloc rather than xmalloc-and-copy.
2238 (new_field): Only allocate one field initially, not two.
2239 Pull ++ out of macro argument. Simplify.
2240 (_initialize_mipsread): Avoid initialization of importd
2241 global_psymbols and static_psymbols.
2243 * symfile.c (psymtab_to_symtab): Depend on XXX_psymtab_to_symtab
2244 to properly set pst->symtab; avoid searching for it.
2245 (symfile_fns): Improve comments, add a FIXME.
2246 * dbxread.c: Update comments to reflect symfile protocol.
2247 (read_ofile_symtab, end_symtab): Return the symtab.
2248 (psymtab_to_symtab_1): Set pst->symtab.
2250 * coffread.c (coff_symfile_read): tell condense_misc_bunches
2251 whether we're mainline.
2253 * symfile.h (sym_fns): Remove unused sym_discard member.
2254 * coffread.c, mipsread.c, dbxread.c: Remove XXX_symfile_discard.
2256 * mtrace.c (mtrace): Take effect if mallwatch is set, even if
2257 the environment variable is not.
2258 * infcmd.c (finish_command): Use filtered printfs.
2259 * cplus-dem.c: Add struct tags to a few unnamed structs.
2260 * valops.c (value_coerce_array): Improve comments.
2261 * valprint.c (type_print_varspec_suffix): Print array size only
2262 if greater than zero.
2263 * m88k-tdep.c: Shift some lines left by one space, that had
2264 apparently been trashed at some point.
2265 * TODO: More things to do, a few got done.
2267 Thu Jul 18 22:46:05 1991 John Gilmore (gnu at cygint.cygnus.com)
2269 * symtab.h (LOC_EXTERNAL): Eliminate in favor of LOC_STATIC.
2270 (ldsymoff, ldsymlen, globals_offset, statics_offset): Improve
2272 * dbxread.c (read_dbx_symtab): LOC_EXTERNAL -> LOC_STATIC.
2273 * expread.y, findvar.c, symmisc.c: Ditto.
2274 * printcmd.c (address_info): Update printed forms of LOC_
2275 symbols. Elim LOC_EXTERNAL.
2276 (print_frame_args): Keep track of param stack offsets before
2277 re-looking up to find the local register param is kept in.
2279 * mipsread.c: Use <symconst.h> and <sym.h> rather than <syms.h>.
2280 Further integration of mipsread into gdb. Eliminate unused
2281 routines, duplicate declarations. Handle static symbols in
2282 psymtabs as well as external symbols. When reading symtabs,
2283 insert symbols into the correct block (global, static, or a local
2285 (read_mips_symtab, parse_partial_symbols): Don't pass useless
2287 (mipscoff_symfile_read): Don't call select_source_symtab.
2288 (parse_symbol): Use SYMBOL_VALUE_ADDRESS where appropriate,
2289 rather than SYMBOL_VALUE.
2290 (parse_external): Comment clobbering of top_stack.
2291 (parse_partial_symbols): Update comments. Allocate and parse
2292 static symbols as well as external symbols. FIXME, enum values
2293 are not handled in this pass, but should be. Inline new_psymbol.
2294 Use SYMBOL_VALUE_ADDRESS.
2295 (psymtab_to_symtab_1): Read symbols into global static block
2296 by default (until enter some function's local block context).
2297 (sort_blocks): Clean up STATIC_BLOCK as well as GLOBAL_BLOCK.
2298 (destroy_all_symtabs, new_psymbol): Eliminate, unused.
2300 * source.c (select_source_symtab): Select a source symtab
2301 from either the symtabs or, failing that, the psymtabs.
2302 (list_command): Update error message.
2303 (forward_search_command, reverse_search_command): Use getc, not
2304 fgetc, for speed. FIXME, add comment about buffers that die if
2305 overrun by long line.
2307 * values.c (unpack_field_as_long, modify_field): Avoid shifting
2308 by an entire word, which is not portable, if we have a 32-bit
2309 field. (Code in dbxread.c already turns such bitfields, if
2310 aligned, into ordinary ints, but fixing this will help for other
2311 symbol formats and for future changes.)
2312 * core.c (core_open): Handle ANSI const brain death.
2313 * utils.c (vprintf): Fix varargs typo.
2315 Sun Jul 14 00:42:53 1991 John Gilmore (gnu at cygint.cygnus.com)
2317 * findvar.c (find_var_value): Handle &function better.
2318 * TODO: Document work needed on &fn and &array.
2319 * printcmd.c (print_address_symbolic): New arg is the prefix
2320 to print if a name is printed.
2321 (print_address_demangle): Honor "set print address" now.
2322 Use new arg above to improve spacing of output.
2323 * valprint.c (val_print): When printing function pointers,
2324 print symbolic form too.
2325 * breakpoint.c (breakpoint_1): Use new print_address_symbolic.
2327 Mon Jul 8 19:02:46 1991 John Gilmore (gnu at cygint.cygnus.com)
2329 * core.c (memory_error): Reword error msg to mislead less.
2331 * mips-pinsn.c (print_insn_arg 'd'): Print $ with reg name.
2333 * mipsread.c (read_mips_symtab, read_the_mips_symtab,
2334 parse_partial_symbols): Use newer BFD internals (external_filehdr
2335 and external_aouthdr), byte-swap the fields that we care about
2336 before using them, and make the file header data local to
2337 read_the_mips_symtab rather than global.
2339 Sat Jul 6 01:34:15 1991 John Gilmore (gnu at cygint.cygnus.com)
2341 * ns32k-opcode.h (movmw, movmd): Fix opcodes. Bug fix
2342 from Rune Nerg}rd <runene@ifi.uio.no> on 5 Jul 1991.
2344 * main.c (command_line_input): Flush stdout and stderr
2345 before every call to readline. This reportedly fixes a bug
2346 that comes up in Sys V running emacs-gdb and/or xxgdb,
2347 when stdin/out are pipes or sockets.
2349 Thu Jul 4 14:47:06 1991 John Gilmore (gnu at cygint.cygnus.com)
2351 * configure.in, Makefile.in: Avoid rebuilding "depend" as much.
2352 Avoid declaring Makefile dependencies, because GNU Make stupidly
2353 tries to update it if we do.
2355 * coffread.c: Revise for minor changes to bfd internal coff
2358 * configure: If -template= is given a relative path, make it
2359 absolute before recurring in subdirectories.
2361 * configure, configure.in, Makefile.in: Install "configure" script
2362 as replacement for config.gdb.
2363 * config.gdb, Makefile.dist, Makefile.sdir: Remove
2364 * README: Update for configure, mostly. FIXME.
2366 * Add dec3100 as equivalent to littlemips. Indicate in all host &
2367 target config files that they are for the host. When the lines
2368 get copied into the Makefile, this makes it more obvious what's
2371 Mon Jun 24 23:49:07 1991 John Gilmore (gnu at cygint.cygnus.com)
2373 * sparc-opcode.h (trap opcodes): Avoid leading spaces or
2374 tabs, which end up in the disassembler output inadvertently.
2376 Wed May 29 23:01:03 1991 John Gilmore (gnu at cygint.cygnus.com)
2378 Make it compile cleanly in an ANSI GCC2 environment.
2380 * blockframe.c: <stdio.h>
2381 * cplus-dem.c: free takes a void *, ifdef __STDC__
2382 * dbxread.c (read_huge_number): avoid gcc2 bug hoisting calc of
2384 * defs.h (alloca): Avoid doing anything if alloca already def'd.
2385 * stddef.h, stdlib.h: Remove these files.
2386 * symtab.c: Avoid declaring qsort, close.
2387 * symfile.c: Avoid declaring close.
2388 * utils.c (vprintf): Declare "ap" arg as proper va_alist.
2389 * sparc-tdep.c: Avoid including lots of Sun-host-specific files.
2391 Assorted other changes.
2392 * dbxread.c: include "libaout.h", not "liba.out.h".
2393 * printcmd.c (print_frame_args): Set recurse properly for
2394 indentation of struct and array parameters.
2395 * valops.c (value_cast): Allow cast to void.
2396 * infrun.c (resume): If NO_SINGLE_STEP, call machine dependent
2397 single_step() in a target-independent fashion.
2398 * sparc-tdep.c (single_step): Don't call ptrace ourselves, just
2399 set up to be ready to continue. This makes us target independent.
2400 * infptrace.c (child_resume): Remove call to single_step; now
2401 can single step a SPARC target of any kind.
2403 Wed May 22 18:18:24 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
2405 * Makefile.dist, doc/gdb.texinfo, doc/*-m4.texinfo: split up GDB
2406 docn into separate sections---basically chapters, plus two loose
2407 pieces that can be configured to go in different places. This
2408 allows GNU m4 to preprocess the manual without coredumping.
2410 * Makefile.dist: tell TeX where to find texinfo.
2412 Mon May 20 12:15:04 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
2414 * Makefile.dist, doc/gdb.texinfo: respectively create, and use,
2415 the new target "rdl-apps.texinfo" which captures the Makefile
2416 variable that records where to find the Readline libraries.
2418 Sun May 19 05:36:59 1991 John Gilmore (gnu at cygint.cygnus.com)
2420 * tahoe-pinsn.c: #include "tahoe-opcode.h", not "opcode.h".
2421 * tm-tahoe.h (FIX_CALL_DUMMY): Ignore more parameters.
2422 * defs.h (const, volatile): Only define if not already defined.
2423 * Makefile.dist (gdb.tar.Z): Create doc subdir w/out CVS/RCS crud.
2425 * README: Update for release 3.95.
2426 * config.gdb: Don't create readline dir in subdir builds.
2427 * main.c: Include with "..." form for non-system include files,
2428 so "gcc -MM" for "make depend" works.
2429 Include readline files with "...h" rather than <readline/...h>.
2430 * mipsread.c: Include "ecoff.h" rather than "intel-coff.h".
2432 * coffread.c: Undo minor damage done by Rich Pixley. Use
2433 different internal and external representations of COFF
2434 data structures. Use new BFD routines for swapping them in and
2436 * symfile.c (free_named_symtabs): Avoid freeing file names that
2437 are null or empty. Old i960 tools seem to produce files that
2438 claim to have empty names, causing each successive file read
2439 to blow away the previous one.
2440 * sparc-xdep.c (deferred_stores): Repair minor damage by Rich.
2441 Move deferred_stores to top of file, but don't separate its
2442 #define's from its variable. Add commentary.
2443 * Makefile.dist: Fix Rich damage; undo "configure" changes in
2444 favor of keeping the (working) config.gdb. Move readline
2447 Fri May 17 12:49:56 1991 Per Bothner (via gnu at cygint.cygnus.com)
2449 * dbxread.c (read_struct_type): Try to handle g++ version 1 MI

2456 * Makefile.dist: added readline/inc-*.texinfo to dependencies for
2459 * readline/inc-history.texinfo, readline/inc-readline.texinfo:
2460 applied various small fixes due to or inspired by RMS comments
2462 * doc/gdb.texinfo: finished using all RMS comments, save those for
2463 appendices on readline and cmd history (which are in other source
2466 Thu May 16 18:06:05 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
2468 * doc/gdb.texinfo: (1) Updated w/ref to RMS comments through
2469 chapter 9; (2) documented 'break' command's menu mode for
2470 overloaded names, in response to hgs problem report C++ p-31
2472 Wed May 15 11:02:48 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
2474 * doc/gdb.texinfo: (1) better introductory example; (2) more
2475 consistent use of @code, @samp, @file, @kbd throughout; small
2476 cleanups to first three nodes; (3) new "Contributors" node;
2477 (4) Appendix, Renamed Commands; (5) divert specialized startup
2478 instructions to "Targets" chapter for generic manuals, while
2479 leaving them up front for manuals specific to specialized
2480 environments; (6) apply fixes from RMS comments through chapter 4.
2482 * pretex.m4: modify explanatory text slightly (and redefine
2483 "regexp") to keep GNU m4 from complaining. (It still crashes
2484 later, but one step at a time...)
2486 Wed May 15 10:32:12 1991 John Gilmore (gnu at cygint.cygnus.com)
2488 * readline/readline.c (update_line): Avoid dereferencing a pointer
2489 before comparing it to its bounds. Saber caught this.
2490 (init_terminal_io): Don't set BC from the "pc=" termcap variable,
2491 and only set PC if tgetstr returned non-null. Saber caught this.

2495 * Makefile.dist: put gdb.dvi stuff (updated to use M4 preprocessor
2496 stuff for config manual) here where it counts; updated
2497 to use new subdir structure (gdb/doc/).
2499 * Makefile: generated from above via
2503 * gdbint.texinfo: added instructions on generating gdb.info* files
2504 locally for release. These are ordinary info
2505 files, formatted from gdb.texinfo (via gdb-all.texinfo, see
2506 Makefile)---but due to use of texinfo 2, can't count on makeinfo
2507 to generate these, so we distribute them already formatted.
2509 * gdb.texinfo: included full Info node and menu crud (as generated
2510 by C-u M-x texinfo-master-menu using the texinfo-2 elisp code).
2512 * Makefile: updated "gdb.dvi" target to use M4 preprocessor;
2513 put in comments-for-future gdb.info target (one day makeinfo will
2516 Tue May 14 13:51:36 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)
2518 * gdb.texinfo: Updated to include new or old undocumented
2519 commands, at least the following (perhaps some others I forgot to
2520 record): info f, info float, info path, info program, info s, info
2521 set, info source, info terminal, info types, info user, set/show
2523 Also covered all recent GDB command renames for v4.
2525 Mon May 13 14:57:46 1991 John Gilmore (gnu at cygint.cygnus.com)
2527 * mipsread.c: Rather than keeping count of how many symtabs
2528 and psymtabs we have, for sorting purposes, count them when
2529 we need to sort. This fixes bug in rereading of symbol tables.
2531 Fri May 10 15:43:33 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)
2533 * infcmd.c: renamed "info path" to "show paths"

2548 symtab.h, target.c, target.h: Lint.
2549 * core.c: setup and select frame after reading shared libs,
2550 else reading shared libs will clobber them. Lint.
2551 * utils.c (error): Force out any buffered wrap text.
2553 Fri May 3 22:01:56 1991 John Gilmore (gnu at cygint.cygnus.com)
2555 * remote.c: Remove decls of memory_insert_breakpoint
2556 and memory_remove_breakpoint, no longer used. (Suggestion of
2559 * Makefile.dist: use ${subdir} in paths of BFD and LIBIBERTY,
2560 to make it easier to interface to "configure"'d libraries.
2562 Fri May 3 13:10:01 PDT 1991 Roland Pesch (pesch at fowanton.cygnus.com)
2564 * valprint.c: introduce "set p", "set pr", "show p" and "show pr" as
2565 aliases for set/show print.

2994 * cplus-dem.c: Use CPLUS_MARKER not '$'. If CPLUS_MARKER isn't
2995 defined, define it to '$'.
2997 * arm-opcode.h: New file (same contents as before; it had
2998 just been left out of the distribution for a long time).

3069 New function to give correct error message.
3071 Thu Apr 11 17:19:41 1991 Jim Kingdon (kingdon at cygint.cygnus.com)

3074 target.c: Add target_preopen and target_command.
3076 (add_target): Call add_cmd and mess with targetlist->doc.
3077 core.c, exec.c, remote-eb.c, remote-nindy.c, remote-vx.c,
3078 remote-vx.68.c, inftarg.c, remote.c: Add doc field to target struct.
3079 Call target_preopen from open routine.
3081 * main.c: Rename editing_info to show_commands.

3103 * symmisc.c (same): same.
3104 (free_symtab): Make non-static.
3105 * symtab.h (free_symtab): Declare as exported void fn now.
3106 * dbxread.c (end_symtab, end_psymtab): Change comments.
3107 (initialize_dbxread): Call dbx_new_init() in case the first
3108 command is add-symbols.
3109 * target.c (dummy_target): Permit add_syms_addr_command.
3111 Sat Apr 13 14:46:07 1991 John Gilmore (gnu at cygint.cygnus.com)
3113 Permit symbols to be superseded when new symbol files have
3114 been read in, particularly for VxWorks.
3116 * dbxread.c (read_dbx_symtab): Allow N_SOL to cleanly take us back
3117 to the main file, as well as to include files. Also, put global
3118 functions into the global psymtab, to make "i fun" work.
3119 (end_psymtab): Free named symtabs and psymtabs for a file, once a
3120 new psymtab for it has been read.
3121 * coffread.c (end_psymtab): Free named symtabs and psymtabs for
3122 a file, once a new symtab has been read for it.
3123 * mipsread.c: FIXME. We need to do the same for MIPS, but it
3124 looks harder to determine the top-level block before it's been
3125 queued to the psymtab list.
3127 * symfile.c (symbol_file_add): Use filtered printing and wrap it.
3128 If we have wiped out any old symbol tables, clean up at end of
3130 (symbol_file_command): Don't reference symfile_fns if it's zero.
3132 * symtab.h (GLOBAL_BLOCK, STATIC_BLOCK, FIRST_LOCAL_BLOCK): New
3133 defines for the blocks of a blockvector that contain global and
3134 file-static symbols and the first of the smaller scope contours.
3135 * symtab.c (lookup_symbol, find_pc_symtab, find_pc_line,
3136 decode_line_1, make_symbol_completion_list): Use the above.
3137 * coffread.c (end_symtab, patch_opaque_types): Ditto.
3138 * dbxread.c (end_symtab): Ditto.
3139 * expread.y (block): Ditto.
3140 * mipsread.c (throughout): Ditto.
3141 * symmisc.c (free_named_symtabs): Ditto.
3143 * symtab.c (list_symbols): Process the first symbol of the
3144 static psymbols list.
3145 (types_info): Restore this function from its untimely #if 0.
3146 It's not perfect, but it is better than nothing.
3147 (_initialize_symtab): Restore "info types".
3149 Thu Apr 11 05:23:19 1991 John Gilmore (gnu at cygint.cygnus.com)
3151 * m68k-stub.c: Remote stub for 680x0's, created from
3152 rem-m68k.shar (which is removed).
3153 * nindy-share/{Makefile,Onindy.c,blout.h,env.h,nindy.c,ttyflush.c}:
3154 Remove RCS log stuff now that we use CVS and it blows our diffs.
3156 Wed Apr 10 14:18:06 1991 John Gilmore (gnu at cygint.cygnus.com)
3158 * symmisc.c (free_named_symtab): Make it work, in its current
3159 kludgy fashion. Change result to indicate if we blew away bkpts.
3160 * dbxread.c (end_symtab): Accumulate result from
3161 free_named_symtab and print warning if we blew user's state.
3162 * symfile.h: free_named_symtab now returns an int.
3164 Mon Apr 8 23:57:43 1991 John Gilmore (gnu at cygint.cygnus.com)
3166 * dbxread.c (dbx_symfile_read): Initialize psymbol list if this
3167 is the first symbol read, even if not mainline.
3168 (dbx_psymtab_to_symtab): symfile might be zero, cope.
3169 * exec.c (exec_ops): Add_syms_addr is valid in our tvec.
3170 (set_section_command): New command ("section xxx yyy" -- should
3171 be renamed to "set section xxx yyy" FIXME) which sets the
3172 base address of a section of the exec file, overriding the
3173 virtual address that BFD reports.
3175 Fri Apr 5 17:14:39 1991 John Gilmore (gnu at cygint.cygnus.com)
3177 * exec.c: Add add_syms_addr_command to exec_ops, so you can
3178 load symbols at any address while examining an exec file.
3180 Thu Apr 4 10:09:35 1991 John Gilmore (gnu at cygint.cygnus.com)
3182 * tm-i386v.h (FLOAT_INFO): Don't define it, since the code
3183 for printing the float info is host-dependent, not
3184 target-dependent. FIXME.
3185 * i386-pinsn.c: Move #includes to top, remove useless ones.
3186 * i386-tdep.c: Don't bother including <.../reg.h> since we
3187 don't use it (and it doesn't exist on host systems).
3189 * ieee-float.c (ieee_extended_to_double): Convert NaN to Inf.
3190 Convert negative numbers properly.
3191 (ieee_test): Make numbers really random; fix format arg.
3193 * infcmd.c (attach_command, detach_command): Don't repeat on CR.
3194 * core.c (core_detach): Unpush core_ops, which might not be on
3195 top. We used to just pop the top, which broke things. Don't
3196 need dont_repeat() any more.
3197 (core_file_command): Psst! Don't repeat it.
3198 * remote-nindy.c (nindy_detach): Don't need dont_repeat() now.
3199 * expprint.c (print_subexp): Avoid switch fallthru on
3200 BINOP_ASSIGN_MODIFY, so we can print += and such.
3201 * frame.h: Fix typo.
3202 * inflow.c (kill_command): After killing inferior, print our
3203 current frame in the core file, if we have one.
3204 (generic_mourn_inferior): When inferior dies, either select
3205 the current frame (in the new target, e.g. core file), or
3206 set both the current and selected frames to NULL.
3208 Changes from Peter Schauer.
3210 * infptrace.c: Avoid <sys/ptrace.h> on USG.
3212 * Make all file names fit in 14 characters (sigh and damn!):
3213 mv hp300hpux-xdep.c hp300ux-xdep.c
3214 mv symmetry-xdep.c symm-xdep.c
3215 mv symmetry-tdep.c symm-tdep.c
3216 mv convex-opcode.h convx-opcode.h
3217 mv tm-vxworks960.h tm-vx960.h
3218 mv tm-vxworks68.h tm-vx68.h
3219 mv Makefile.srcdir Makefile.sdir
3220 mv gdb-int.texinfo gdbint.texinfo
3221 mv remote-sa.m68k.shar rem-m68k.shar
3222 mv remote-multi.shar rem-multi.shar
3223 * Makefile.dist, README, config.gdb, convex-pinsn.c,
3224 tconfig/symmetry, tconfig/vxworks960, tconfig/vxworks68,
3225 xconfig/hp300hpux, xconfig/symmetry: Change names to shorter
3228 * command.c (user_info_1, user_info): New command for listing
3229 the user-defined commands.
3231 Wed Apr 3 15:00:26 1991 John Gilmore (gnu at cygint.cygnus.com)
3233 * dbxread.c (really_free_pendings): Clear file_symbols
3234 and global_symbols after freeing them; otherwise, running
3235 this function twice (if it appears twice on the cleanup
3236 chain), we try to free things twice.
3238 * dbxread.c (read_dbx_symtab): Calculate end_of_text_addr
3239 based on text_addr (the address of text in core), not on addr (the
3240 offset between text in the .o file and in core). This change
3241 is from Peter Schauer.
3243 * main.c: Define ALL_CLEANUPS as a cast of zero.
3244 (return_to_top_level): Use it.
3245 (main): Do all cleanups after each command run as part
3246 of the gdb startup sequence. Also do all cleanups before
3247 entering the command loop, and every time we exit the command
3248 loop and reenter. Before, the cleanups from the startup sequence
3249 were being left undone until the first error!
3250 (command_loop): Rename do_nothing cleanup to command_loop_marker
3251 so we can see it easily when examining the cleanup chain.
3252 (init_signals): Add another do_nothing for signal handling.
3253 (quit_command): Only try to kill target if it has execution.
3254 Problems in the target stack got us into a state where
3255 inferior_pid was nonzero but none of the targets had execution.
3256 In this state you couldn't exit gdb.
3258 * dbxread.c: Two changes from Peter Schauer.
3259 (echo_command): Fflush output after an echo command.
3260 (show_history): Pass all args to cmd_show_list.
3262 * utils.c (init_malloc): Call mtrace to turn on tracing
3263 if the environment variable MALLOC_TRACE is set to a file name.
3264 * mtrace.c: Add source file which provides a log of every malloc,
3265 free, and realloc to a trace file.
3266 * mtrace.awk: Add source file which analyzes the trace file.
3267 * Makefile.dist (GNU_MALLOC, MALLOCSRC): Add mtrace.{c,o,awk}.
3268 (VERSION): Roll to 3.94.3.
3270 * breakpoint.c (breakpoint_1): Add a space to "i watch" output.
3271 (check_duplicates): Don't bother with watchpoints.
3272 (set_raw_breakpoint): Comment about danger of this routine.
3273 (watch_command): Parse and eval all args before calling
3276 * solib.c (find_solib): Avoid error in referencing memory to
3277 see if any more shared libraries have been added. This is
3278 particularly useful if the target has terminated. Bug reported
3281 Changes from Peter Schauer <pesrem@regent.e-technik.tu-muenchen.de>
3282 in bringing up 3.94.2 on the Sun-3.
3284 * Makefile.dist: Include CFLAGS in rule for cplus-dem.o.
3285 * breakpoint.c (enable_breakpoint): Check for valid watchpoint
3286 expression (in scope) before reenabling watchpoint.
3287 * signame.c (init_sigs): Add missing declaration of i, fix
3288 sys_siglist declaration.
3289 * source.c (list_command): Fixed range computation to use
3291 * stack.c (backtrace_command): Do not allow command if target has
3292 no stack, print informative error message.
3293 * target.c (target_command): Do not write into command line
3294 because this fails if the target command is used in a user defined
3295 command. [This change was enhanced by gnu to support any-
3296 unique-prefix matching on target names.]
3297 * valops.c (value_struct_elt): Avoid infinite loop on an
3298 erroneous attempt to print the member of function (try p main.p).
3300 Mon Apr 1 17:05:45 1991 John Gilmore (gnu at cygint.cygnus.com)
3302 * expread.y (name_no_typename): Avoid reduce/reduce errors
3303 caused by ambiguity in handling NAME_OR_INT and NAME_OR_UINT.
3304 Since the GDB parser really doesn't use name_no_typename in a
3305 name-only context, the parser can't tell the diff between
3306 names and numbers here. Avoid allowing a name_no_typename
3307 to be a NAME_OR_*INT to resolve the conflict.
3309 Sun Mar 31 20:12:07 1991 John Gilmore (gnu at cygint.cygnus.com)
3311 Bugfixes from Mark Fox (markf@wrs.com) (test=testField.c):
3313 * valprint.c (val_print_fields): bitfield printing didn't handle
3314 byte order. Indirect through a few more fns to cope.
3316 * values.c (modify_field): also cope with byte order.
3318 Sat Mar 23 10:02:21 1991 John Gilmore (gnu at cygint.cygnus.com)
3320 Cleanup for release 3.94.2:
3322 * Makefile.dist: Pull REMOTE_OBS. Fix saber includes for BFD
3323 include files. Roll version to 3.94.2.
3325 * coffread.c (init_stringtab): Read length into unsigned char
3326 array before swapping; don't assume 32-bit longs.
3328 * target.c (target_info): Don't bother with get_sym_file, just use
3329 the symfile global variable.
3330 * symtab.h, symfile.c (get_sym_file): Delete it.
3332 * dbxread.c (dbx_symfile_init): Don't depend on long == 4 bytes.
3333 (define_symbol): Set symbol line number to 0 if not gcc-compiled.
3334 (read_type): Replace one more error() with complain().
3336 * mipsread.c (parse_partial_symbols): Replace printf with complain.
3338 * i960-tdep.c: Fix copyright attribution.
3340 * config.gdb: Quote all backquotes in doublequotes. You can
3341 quote me on that. BSD 4.4 shell found this one.
3343 * infptrace.c (throughout): The third argument to ptrace is an
3346 * infrun.c (wait_for_inferior): When program has terminated, we
3347 have to call target_terminal_ours before we pop that target off
3348 the stack (e.g. before a call to target_kill or
3349 target_mourn_inferior). This fixes problem where a program
3350 terminates, then GDB stops for (tty output) and you have to type
3351 "fg" to the shell to resume it. FIXME: This code for what to
3352 do after termination really should be in normal_stop instead.
3354 * gdbcore.h (read_memory_check): Change declaration; it changed
3357 * terminal.h: Include <sgtty.h> before <sys/ioctl.h>, since in BSD
3358 4.4 prereleases, this avoids a bug in their sgtty compatability
3360 * remote.c: Use terminal.h rather than hand-rolling the same.
3362 * signame.c, signame.h (psignal): Arg is unsigned, not int.
3363 * utils.c (strsave, strstr): Fix arg types.
3364 * valprint.c (val_print): lint
3366 MIPS symbol table support from Per Bothner:
3368 * symfile.c (symtab_fns): Remove initializer table that needs to
3369 be hacked for each new symbol file format supported.
3370 (add_symtab_fns): New function, chains symbol table
3371 handlers into the global list.
3372 (symfile_init): Search this list.
3373 * symfile.h: Add next pointer, declare add_symtab_fns.
3374 * coffread.c (_initialize_coffread): Call add_symtab_fns.
3375 * dbxread.c (_initialize_dbxread): Call add_symtab_fns.
3377 * mipsread.c (psymtab_to_symtab_1): return void instead of (struct
3378 symbol *). Thus, we no longer need the hack to trash
3379 pst->filename. Good, since that hack confused code in symfile.c!
3381 (reorder_symtabs, destroy_all_symtabs): Removed static
3382 all_symtabs, which was used to qsort symtabs in reorder_symtabs.
3383 Instead, the latter now uses a temporary array (stack-allocated
3384 from an obstack, and then freed).
3386 (parse_symbol): Added a hack to fix up BLOCK_{START,END} if they
3387 haven't been set in the outermost stBlock of a procedure. This was
3388 a problem with f77 binaries on Ultrix 4.?.
3390 (new_symtab, new_symbol, new_type): Continue changing code to use
3391 obstacks more and otherwise conform to dbxread internal style.
3392 Made the free_code of symtabs be free_linetable (as in dbxread)
3393 instead of free_contents. This implies memory leaks when reading
3394 a new symbol table, until the conversion is finished. Did change
3395 (struct symbol) and (struct type) to be allocated on the
3396 symbol_obstack. Blocks and blockvectors are among the things
3399 * mipsread.c (parse_partial_symbols, parse_fdr): It hasn't been
3400 tested much, but it solved one problem (reported by Meissner), and
3401 cleans up some other things. The problem happened when an
3402 included file contains actual code (functions) and not just
3403 definitions. The mips coff is a little inconvenient there, since
3404 it may cause a procedure to be mapped to the wrong psymtab.
3406 * mips-tdep.c (heuristic_proc_desc): Minor cleanup.
3407 * mips-xdep.c (fetch_core_registers): Minor cleanup. FIXME,
3408 this will need work for the new core paradigm.
3410 Opcode patches from the net:
3412 * mips-opcode.h: fix incorrect disassembly of the mfc1, cfc1, and
3413 ctc1 instructions. Also, the cvt.d.w and cvt.s.w instructions were
3414 missing altogether - they are added here. From Bruce Bauman.
3415 * mips-opcode.h: The low mask for C0 instructions was too small.
3416 From Garrett Lau. I modified the fix to check the entire 32-bit
3419 * ns32k-opcode.h: Fix opcodes for deiw and deid. From Bruce
3422 Thu Mar 21 12:56:46 1991 John Gilmore (gnu at cygint.cygnus.com)
3424 Roll in changes from Per Bothner (Tue, 25 Sep 90 11:11:04):
3426 * dbxread.c (read_type): Pointer subtraction (value_sub in
3427 valarith.c) sometimes failed because the types of the
3428 pointers being subtracted were not identical.
3429 These differed because dbxread.c was allocating pointer types
3430 using dbx_alloc_type+smash_to_pointer_type instead of
3431 lookup_pointer_type. I failed to find a justification for the
3432 former, so I changed it to use the latter. Similarly, I
3433 replaced smash_to_function_type by lookup_function_type,
3434 and smash_to_reference_type by lookup_reference_type.
3436 * mipsread.c (parse_symbol, upgrade_type, parse_procedure,
3437 _initialize_mipsread): corresponding changes.
3439 * symtab.c (smash_to_{pointer,reference,function}_type): eliminate.
3441 * source.c (mod_path): Do tilde_expand on each component of the path,
3442 rather than on the (list of) paths as a whole.
3443 (print_source_lines): Set first_line_listed in addition to
3444 current_source_symtab and current_source_line. If the source was
3445 not findable, after a "dir" command to fix the problem,
3446 a "list" would get the wrong lines.
3448 While I was there... (gnu):
3450 * dbxread.c (read_type): Change error to complaint.
3452 Thu Mar 21 12:56:46 1991 John Gilmore (gnu at cygint.cygnus.com)
3454 First attempt at detailed understanding of symbol table memory alloc.
3456 * dbxread.c (dbx_symfile_read): Free our string table if we
3457 aren't the mainline. Free the "info" struct since we're done with
3459 (init_psymbol_list): Free any previously allocated psymbol lists.
3460 (): FIXME: Should realloc-down the psymbol lists when done reading
3461 the main symbol file?
3463 * symmisc.c (free_symtab): Free fullname field too.
3465 * xm-hp300hpux.h (USG): #undef then #define so Makefile can -D.
3466 (REGISTER_ADDR): Make result type unsigned int.
3468 * xconfig/{i386*,hp300hpux,altosgas,altos}: All config files that
3469 define REGEX must also define REGEX1 (its dependency).
3471 Tue Mar 19 21:28:57 1991 John Gilmore (gnu at cygint.cygnus.com)
3473 * tconfig/i960: No longer works, points you at vxworks960 or
3476 * xgdb.c, XGDB-README: Remove file. Users can get the much
3478 * Makefile.dist: Remove all trace of xgdb.
3480 * breakpoint.c (breakpoint_1): Pass demangle arg to
3481 print_address_symbolic.
3482 (clear_breakpoints): Remove unused function.
3483 (breakpoint_re_set_one): Guts of breakpoint_re_set.
3484 (breakpoint_re_set): Use catch_errors to do them all anyway.
3486 * gdb-int.texinfo (Host versus Target): Add section on what is
3487 a "host" feature versus what is a "target" feature.
3489 * infcmd.c (path_command, path_info): Handle the PATH variable
3490 (object search path) as conveniently as the source search path.
3491 * environ.c (set_in_environ): Set some vars in GDB's environment,
3492 in addition to the child's. PATH, G960BASE, G960BIN for starters.
3493 * source.c (mod_path): New function, from guts of
3494 directory_command, modifies a path. Used by path_command.
3495 (directory_command): Call it.
3496 * defs.h (strsave): Declare.
3498 * utils.c (sevenbit_strings): Add new printing option.
3499 (printchar): Use it.
3500 (strsave): Provide this handy helper routine.
3501 (set_width_command): Rename set_screen_width_command.
3502 (_initialize_utils): "set screen-width" => "set width";
3503 "set screen-height" => "set height"; add sevenbit-strings.
3505 * infcmd.c (do_registers_info): Print floating point registers
3506 in raw hex as well as float format, regardless of whether it is
3507 a "virtual" convertible register.
3508 * tm-sparc.h (PRINT_REGISTER_HOOK): Print every pair of float
3509 regs as a double, just in case it's being used that way.
3510 * values.c (unpack_long): Comment on array/function coercion.
3511 (unpack_double): Argument is in target byte order now. For
3512 integer arguments, just call unpack_long and float the result.
3513 * m68k-tdep.c: include defs.h for "const" handling.
3514 * remote-nindy.c: Use ieee-float stuff.
3515 (nindy_fetch_registers): Unpack double regs to host double, then
3517 (nindy_store_registers): Pack extendeds to host double, flip
3518 around by misusing unpack_double, send as target double.
3520 * tm-vxworks68.h (FRAME_CHAIN): Handle current frame pointer of
3521 zero, as when stopped at the first instruction of a process.
3523 * blockframe.c: Fix filename in comment (param.h => tm.h).
3524 * sparc-tdep.c (skip_prologue): More explicit nudging comments.
3525 * tm-68k.h: Fix typos.
3527 Fri Mar 15 01:09:34 1991 John Gilmore (gnu at cygint.cygnus.com)
3529 Changes from a bringup on the DEC Vax under Ultrix 4.0.
3531 * coredep.c (fetch_core_registers): Pass end-address of register
3532 section to register_addr as expected. Don't call supply_register
3533 if we'd just pass it garbage.
3535 * dbxread.c (read_dbx_symtab): Skip N_NSYMS on Ultrix.
3537 * exec.c (xfer_memory): Use boolean xfer_fn result, not int.
3539 * target.c (push_target, target_info): Cast enums to int for < or
3542 * stack.c (print_frame_info): Identify source file & line
3543 even if we can't print it.
3545 * xm-vax.h (MISSING_VPRINTF): No longer missing in Ultrix V4.0.
3547 Sat Mar 9 10:08:20 1991 John Gilmore (gnu at cygint.cygnus.com)
3549 Clean up IEEE floating point support.
3551 * ieee-float.h: New file.
3552 * ieee-float.c: Write real routines to convert between host
3553 doubles and various target IEEE extendeds.
3554 * m68k-xdep.c: Eliminate assembler code for extended floats.
3555 * xconfig/{3b1,altos,altosgas,hp300bsd,isi,news,news1000,sun2os3,
3556 sun2os4,sun3,sun3os3,sun3os4}: Eliminate use of m68k-xdep.o.
3557 * tm-i960.h, tm-68k.h (REGISTER_CONVERT_TO_VIRTUAL,
3558 REGISTER_CONVERT_TO_RAW): Use ieee_extended_to_double and
3559 double_to_ieee_extended.
3560 * i960-tdep.c: Define ext_format_i960.
3561 * m68k-tdep.c: Define ext_format_68881.
3562 * sparc-tdep.c: Define ext_format_sparc, though unused.
3563 * Makefile.dist (HFILES): Add ieee-float.h.
3564 * inftarg.c: #include "ieee-float.h" for the REGISTER_CONVERT
3567 Obsolete the "coffstrip" program in favor of using BFD's strip.
3569 * nindy-share/coffstrip.c: Remove file.
3570 * nindy-share/nindy.c (coffstrip): Routine to run bfd_strip.
3571 * Makefile.dist: Remove references to nindy-share/coffstrip.c.
3572 * tconfig/nindy960: Remove reference to coffstrip.o.
3574 * Makefile.dist: Roll version number to 3.94.1 (not yet final).
3576 Wed Mar 6 09:56:45 1991 John Gilmore (gnu at cygint.cygnus.com)
3578 * symfile.h: Add symfile_bfd, common between dbxread and coffread.
3579 * dbxread.c: Remove static symfile_bfd.
3580 * infcmd.c (do_registers_info): Add PRINT_REGISTER_HOOK, though
3582 * inftarg.c (child_detach): Pop the child_ops vector if the
3583 detach is successful.
3584 * remote-nindy.c (nindy_create_inferior): Don't push a new
3585 nindy_ops since nindy uses the same one for execution and memory
3587 * core.c (core_ops): Use child_attach and child_create_inferior
3588 rather than default attach and create_inferior functions.
3590 Handle floating point registers in core files.
3592 * sparc-xdep.c (fetch_core_registers): Rewrite for float support.
3593 * sun3-xdep.c (fetch_core_registers): Rewrite for float support.
3594 This version untested since BFD doesn't yet support sun3 core
3596 * hp300hpux-xdep.c: Rewrite fetch_core_registers to new calling
3597 conventions. Fix comments and style. This version has not
3598 been compiled yet, since we have no HP inhouse.
3599 * core.c (get_core_registers): Look for two sections, ".reg"
3600 and ".reg2", and pass both to fetch_core_registers sequentially.
3602 Revise directory path yet again.
3604 * source.c (forget_cached_source_info): Not static any more.
3605 (init_source_path): New default source path is "$cdir:$cwd".
3606 (dir_command): Handle variable arguments ($cdir, $cwd).
3607 (source_info): Print "Compilation directory" rather than
3608 "Originally compiled in" to remind people of $cdir.
3609 (openp): If the path contains $cwd, use current directory.
3610 (open_source_file): If compilation directory is known, replace
3611 first $cdir in path with the compilation directory.
3612 (print_source_lines): Even if we can't print the lines, set the
3613 current symtab and line for future commands like "info source" or
3614 "breakpoint". Also, error message now contains the file name,
3615 line number, and file access error message.
3616 (_initialize_source): Fix help text to describe changes.
3617 * main.c (cd_command): Forget cached source info when we chdir.
3618 * utils.c (strstr): Add simple implementation.
3620 Tue Mar 5 01:41:40 1991 John Gilmore (gnu at fowanton.cygnus.com)
3622 * coffread.c (read_one_sym, init_linetable, init_stringtab):
3623 Byte-swap COFF symbol tables if necessary when reading them in.
3624 Use complain() to replace error message in one spot. Needs
3625 corresponding change in bfd/coff-code.h to make some symbol
3626 swapping routines non-static.
3628 Mon Mar 4 00:53:40 1991 John Gilmore (gnu at cygint.cygnus.com)
3630 Merge changes from Eirik Fuller, for UTek.

3633 * altos-xdep.c, arm-xdep.c, convex-xdep.c, gould-xdep.c,
3634 hp300hpux-xdep.c, infrun.c, inflow.c, infptrace.c, i386-tdep.c,
3635 i386-xdep.c, pyr-xdep.c, mips-xdep.c, remote-eb.c, remote-nindy.c,
3636 remote-vx.c, source.c, standalone.c, stuff.c, sun386-xdep.c,
3637 symmetry-tdep.c, symmetry-xdep.c, umax-xdep.c, utils.c: Eliminate
3638 declarations of errno.
3640 * remote-eb.c: Define B19200 and B38400 as EXTA and EXTB.
3642 * remote-vx.c: Include <sys/time.h> for UTek; Sun gets it via
3643 <rpc/rpc.h> and <rpc/types.h>.
3645 Sat Mar 2 15:47:55 1991 John Gilmore (gnu at cygint.cygnus.com)
3647 * i960-tdep.c (examine_prologue): Add new argument limit,
3648 which stops the scan at the end of the prologue, or at the PC.
3649 This fixes a problem where it walks down into the code for the
3650 user's statements if that code looks like function prologues.
3651 Mark Fox and I have been bouncing this code back and forth, making
3652 small changes to it. Callers changed to match.
3654 Tue Feb 26 01:47:07 1991 Cygnus John Gilmore (cygnus at yuba)
3656 Cleanup for gdb-3.94 release final:
3658 * Makefile.dist: Remove remote-vx.c, remote-nindy.c, and all
3659 the .c files from vx-share and nindy-share, from the various
3660 macros, since they are not found via ALLDEPFILES.
3661 (SFILES): Add tm-i960.h.
3662 (alldeps.mak rule): Break out ALLDEPFILES_MAINDIR and
3663 ALLDEPFILES_SUBDIR. List all the nindy and vxworks subdir files
3665 (TAGFILES_MAINDIR): Change ALLDEPFILES to ALLDEPFILES_MAINDIR.
3666 (gdb.tar.Z): Use ALLDEPFILES_SUBDIR as well as SFILES_SUBDIR.

3670 * am29k-tdep.c: Add contribution line.
3671 (examine_prologue): Cache information about function prologues in
3672 the misc-function-vector to avoid lots of references over the
3673 serial line while examining instructions.
3675 * core.c (core_close): New function made from cleanup_core.
3677 * core.c, exec.c, inftarg.c, remote-eb.c, remote-nindy.c,
3678 remote-vx.c, remote.c, target.c, target.h,
3679 Update target_ops vector to add attach, close, and load entries.
3680 Use add_syms_addr_command, not add_file_addr_command, for
3681 add_file. Break out close routine from existing code.
3683 * dbxread.c (really_free_pendings): Don't free pending_blocks;
3684 they are in an obstack.
3685 (read_dbx_symtab): Relocate end_of_text_addr in the psymtab.
3687 (define_symbol): Add symbol type parameter; change callers;
3688 pass type parameter to DBX_PARM_SYMBOL_CLASS macro to allow
3689 it to influence the symbol class on the i960.
3690 (define_symbol): Swap LOC_CONST's into target byte order.
3692 * exec.c (exec_close): New function.
3693 (exec_file_command): Call it.
3695 * findvar.c (read_relative_register_raw_bytes): Doc byte order,
3696 Fix byte order of frame pointer.
3697 (read_var_value): Result of 0 if var's value can't be found,
3698 e.g. missing FRAME_ARGS_ADDRESS. Byte-swap LOC_CONST and
3699 LOC_LABEL values to target order. Add LOC_LOCAL_ARG.
3700 (locate_var_value): Use read_var_value and use its lazy address
3701 as the location of the var's value. Lint.
3703 * i960-pinsn.c (next_insn): Add routine from vxgdb for scanning
3706 * i960-tdep.c (arg_address, i960_frame_find_saved_regs): Remove
3707 obsolete Intel versions in favor of vxgdb versions.
3708 (check_host, byteswap, byteswap_val, reorder_val): Eliminate
3709 code dealing with byte order of values, which Intel did in host byte
3710 order rather than gdb-4's target byte order.
3711 (i960_frame_chain_valid): Move to nindy-tdep.c.
3712 (examine_prologue, skip_prologue, frame_find_saved_regs,
3713 frame_args_address, leafproc_return, saved_pc_after_call,
3714 pop_frame): Add vxgdb versions from Mark Fox.
3715 (examine_prologue, frame_struct_result_address): Add code
3716 to deal with the saved value of G13 (struct return address
3718 (frame_args_address): Modify Mark's version to prefer the
3719 saved value over the current value in the topmost frame.
3720 Cache result in the frame info to avoid performance hair in
3722 (print_fault): Add gdb960 code for printing faults.
3723 (_initialize_i960): Actually call check_host.
3725 * ieee-float.c (ieee_extended_to_double, ieee_double_to_extended):
3726 add stub routines. FIXME, these currently just return zero!
3728 * infcmd.c (program_info): Use PRINT_RANDOM_SIGNAL.
3729 (attach_command): Call target_attach, not target_open, now.
3731 * infrun.c (normal_stop): Make global, not static, for vx_attach.
3732 (child_attach): Rename from child_open.
3733 (wait_for_inferior): Use PRINT_RANDOM_SIGNAL. If stop_pc is zero,
3734 don't confuse it with a zero step_resume_break_address.
3736 * inftarg.c (child_detach): Eliminate inferior_pid test.
3737 (child_files_info): Clean up message a bit.
3738 (child_ops): Use child_attach, not child_open, to attach.
3740 * mem-break.c: #ifdef out the whole file if BREAKPOINT is not
3741 set (e.g. on VxWorks or NINDY). Move read_memory_nobpt from
3742 findvar.c to here, since it depends on the contents of the
3743 shadow_contents of breakpoints, but keep if #if 0 since it is
3746 * nindy-tdep.c: New file, contains nindy_frame_chain_valid, moved
3749 * printcmd.c (address_info): Handle LOC_LOCAL_ARG. Lint.
3750 (ptype_command, display_command): Eliminate have_inferior_p and
3751 have_core_file_p in favor of target_has_stack or
3752 target_has_execution.
3753 (print_frame_args): Handle LOC_LOCAL_ARG. Eliminate duplicate
3754 code for actually finding the values of arguments, though we still
3755 keep track of the maximum stack offset for use in printing unnamed
3756 arguments. Handle missing FRAME_ARGS_ADDRESS.
3758 * remote-nindy.c (i960_print_fault): Move to i960-tdep.c.
3759 (struct nindy_regs): Define registers passed to/from nindy.
3760 (nindy_fetch_registers, nindy_store-registers): Translate between
3761 nindy and GDB formats for the registers.
3762 (dcache_init): Statically allocate the cache, since it was being
3763 allocated by a malloc that was never freed anyway.
3764 (nindy_create_inferior): Error, not core dump, if no exec file.
3765 (nindy_before_main_loop): Use target_load, not target_add_file.
3767 * remote-vx.c (net_load): Specify large timeout for load
3768 requests. Allow user to break out with INTERRUPT.
3769 (net_break): Remove useless code, clean up. Change callers.
3770 (parse-args, skip_white_space, find_white_space): Clean up arg
3771 parsing to cope with quoted strings.
3772 (net_wait, net_quit): Never call error, just return status.
3773 (vx_read_register, vx_write_register): Cleanup status checking.
3774 #ifdef the code based on which CPU we are using (960 or 68k),
3775 FIXME, this should be completely general but it isn't yet.
3776 (vx_xfer_memory, vx_resume): Cleanup status checking.
3777 (vx_run_files_info): Improve message.
3778 (vx_load_command): Renamed from vx_add_file_command. Allow load
3780 (net_ptrace): Remove unused routine.
3781 (vx_wait): Adopt code from vxgdb960 to cope with broken
3782 connections to target machine and prompt to disconnect. Remove
3783 debug printouts. Map some EVENT_'s to SIGnals.
3784 (add_symbol_stub, vx_open): Print names of object files we found,
3785 and "ok" if we read their symbols OK. Clarify output in general.
3786 (vx_attach, vx_detach, vx_kill): Add these commands.
3787 (vx_convert_from_virtual, vx_convert_to_virtual): Simplify.
3788 (vx_run_ops): Turn off all_mem, to avoid spurious msg in the
3789 "info files" output, and create_inferior, since we already have
3792 * stack.c (frame_info): Replace Frame_unknown with 0.
3793 (print_frame_arg_vars): Handle LOC_LOCAL_ARG.
3794 (return_command): Pop until the PC matches as well as the FP,
3795 so it works even if the FP is shared with another function,
3796 as in "frameless" or "leaf" procedures.
3798 * symfile.c (load_command): renamed from add_file_target_command.
3799 (add_syms_addr_command): renamed from add_file_addr_command.
3800 (add_syms_command): Stub to call target_add_syms.
3801 (_initialize_symfile): Change command names and descriptions,
3802 add-file => add-syms, and load from alias to its own command.
3804 * target.c (kill_or_be_killed, maybe_kill_then_attach,
3805 maybe_kill_then_create_inferior): Default for attempts to start
3806 a process, if one is already running, is to ask about killing
3807 it and retry if yes.
3808 (upstack_create_inferior): #if-0 it, strata obsolete it.
3809 (push_target, unpush_target, pop_target): to_close() a target
3810 before unstacking it.
3811 (target_info): Renamed from target_files_info.
3812 (_initialize_targets): Rename "i files" as "i target", accessible
3815 * target.h: Improve comments about the target_ vectored routines.
3817 * tm-i960.h: Remove NINDY-specific stuff to tm-nindy960.h.
3818 Convert commenting style to standard GNU style.
3819 (DBX_PARM_SYMBOL_CLASS): allow LOC_LOCAL_ARG's to be recognized.
3820 (SKIP_PROLOGUE): No longer a no-op.
3821 (SAVED_PC_AFTER_CALL): Now handles leaf procedures.
3822 (*_REGNUM): Sort register numbers.
3823 (REGISTER_BYTES, REGISTER_BYTE, REGISTER_RAW_SIZE,
3824 MAX_REGISTER_RAW_SIZE, REGISTER_CONVERTIBLE,
3825 REGISTER_CONVERT_TO_VIRTUAL, REGISTER_CONVERT_TO_RAW): Float regs
3826 are now 10 byte extendeds, not 8 byte doubles.
3827 (FRAME_CHAIN_VALID): Make this config-dependent, since it differs
3828 for nindy versus vxworks targets. FIXME, this should possibly go
3829 in the target vector.
3830 (EXTRA_FRAME_INFO, INIT_EXTRA_FRAME_INFO): Cache both
3831 frame_saved_regs and arg pointer with each frame.
3832 (FRAMELESS_FUNCTION_INVOCATION): New leafproc support.
3833 (FRAME_ARGS_ADDRESS): Use cached result.
3834 (FRAME_ARGS_ADDRESS_CORRECT): New, avoids g14 guessing.
3835 (FRAME_FIND_SAVED_REGS): Change arg to subsidiary fn.
3836 (PRINT_RAMDON_SIGNAL): Call print_fault.
3837 (POP_FRAME): Now works.
3839 * tm-nindy960.h: Break this off tm-i960.h. NINDY-specific
3840 option parsing and startup; STACK_END_ADDR, FRAME_CHAIN_VALID,
3841 BREAKPOINT, and DECR_PC_AFTER_BREAK are here.
3842 (ADDITIONAL_OPTION_HANDLER): use target_load, not
3845 * tm-vxworks960.h: Break this off tm-i960.h. VxGDB specific
3846 startup; DECR_PC_AFTER_BREAK, and FRAME_CHAIN_VALID are here.
3848 * valarith.c (value_subscripted_rvalue): Avoid handling
3849 floats and doubles specially; it gave alignment errors. Lint.
3851 * valops.c (value_of_variable, value_of_this): Error if unknown
3854 * valprint.c (print_floating): Bcopy rather than pointer-deref,
3855 to avoid alignment problems.
3856 (value_print): Handle unknown value address.
3857 (cplus_val_print): Two args are ignored; remove them. Change caller.
3858 (val_print): Use unpack_long rather than pointer-deref.
3861 (unpack_long, unpack_double): Use bcopy rather than pointer-deref
3862 to avoid alignment problems.
3863 (value_being_returned): Error if return value unknown.
3864 (set_return_value): Add bogosity warning, FIXME. *
3866 * TODO: A woman's work is never done.
3868 * Makefile.dist: Distribute REMOTE_OBS into tconfig files.
3869 Separate INCLUDE_CFLAGS for use with lint. Add LINTFILES.
3870 Add ieee-float.o to OBS.
3871 * tconfig/{nindy960,vxworks68,vxworks960}: Include the desired
3872 REMOTE_OBS remote-interface files in the TDEPFILES and TM_FILE.
3873 * tconfig/i960: FIXME. Half-merge, produce warning if config'd.
3875 Changes to generalize the VxWorks RPC protocol slightly, to handle
3876 i960 as well as 68000.
3878 * vx-share/dbgRpcLib.h (VX_SOURCE_STEP): Add.
3879 * vx-share/reg.h: Produce i960 regs #ifdef I80960
3880 * vx-share/xdr_ptrace.c: Skip FPA registers if 960.
3881 * vx-share/xdr_rdb.h: Add SOURCE_STEP struct and xdr decl.
3882 * vx-share/xdr_rdb.c: Add xdr_SOURCE_STEP routine.
3883 * vx-share/xdr_regs.c: Add xdr_regs, xdr_fp_status, xdr_ext_fp
3884 for i960. Change xdr_vectors to xdr_opaques for 68k registers,
3885 so they will move in target byte order rather than network
3886 byte order (happens to be the same).
3888 Mon Feb 25 03:41:44 1991 John Gilmore (gnu at cygint.cygnus.com)
3890 * tm-convex.h (END_OF_TEXT_DEFAULT): Remove #if 0'd block.
3892 Sun Feb 24 00:55:53 1991 John Gilmore (gnu at cygint.cygnus.com)
3895 Add contribution lines to various files, showing where they
3898 * breakpoint.c (break_insn, check_break_insn_size,
3899 read_memory_nobpt): Remove to mem-break.c.
3901 * xm-*.h, param-no-tm.h, tm-29k.h, valprint.c: Change BYTE_ORDER to
3904 * tm-29k.h (STAB_REG_TO_REGNUM): Warn user if symbol table
3905 entry has bad register number. This change is not
3906 tested in this release, FIXME.
3908 * frame.h: Eliminate Frame_unknown in favor of a simple zero.
3911 * value.h: Force value's contents field to be aligned to hold
3912 at least a double or a long long (if supported). This avoids
3913 doing bcopy's in and out of the contents field.
3915 (step_1): Avoid coredump under obscure circumstances when we
3918 * symtab.h (misc_info): Add field to misc function vector for
3919 any kind of cached information the target code desires. AMD
3920 29000 uses this to avoid repeating examine_function_prologue's.
3922 * coffread.c: Lint. Remove static symfile, read_section_header.
3923 core.c (have_core_file_p): Lint: remove.
3924 expprint.c (print_subexp): Lint.
3925 infptrace.c, valops.c, valprint.c: lint.
3927 Roll in changes from vxgdb-5.0.1:
3929 * symtab.h: Comment byte order of each address class. Add
3930 LOC_LOCAL_ARG for frame-relative args (960).
3931 expread.y: Use LOC_LOCAL_ARG where LOC_ARG is used.
3932 symtab.c, symmisc.c: ditto.
3934 * infrun.c (init_wait_for_inferior): Clear stop_signal.
3936 * remote.c (remote_resume): Error if resume with a signal.
3938 * symfile.c (prim_record_misc_function): Clear misc_info.
3939 (fill_in_vptr_fieldno): Check stub type of arg.
3941 * valops.c (value_cast): Avoid looking up names of types whose
3942 name we don't know, to prevent coredump. Sun CC produces typedef
3943 rtx and the name of *rtx is zero...
3945 Mon Feb 18 21:16:25 1991 John Gilmore (gnu at cygint.cygnus.com)
3947 Roll in changes from final AMD 29000 port (Tiemann).
3949 tconfig/am29k: Add COFF_ENCAPSULATE and TARGET=TARGET_AM29K
3950 for ../include/a.out.encap.h. This might not work now that BFD
3951 is separately compiled. Instead, BFD support for encap will have
3952 to translate machine type 29k into the right COFF_MAGIC.
3954 * infcmd.c: Remove references to inferior_pid that aren't used
3955 in actual ptrace calls; use target_has_execution, etc.
3956 (have_inferior_p): Remove function.
3957 (program_info): Print target info rather than "process number";
3958 avoid gratuitous messages unless from_tty.
3959 (run_stack_dummy, finish_command): Set proceed_to_finish.
3960 infrun.c: Remove inferior_pid refs. Decl & init proceed_to_finish.
3961 main.c: Lint. Lose have_inferior_p().
3962 inferior.h (have_inferior_p): Remove, lint.
3963 (proceed_to_finish): Add flag to ask that all regs be saved
3964 by normal_stop, for the few commands that need it, speeding up
3965 serial I/O. Add comments to stop_registers.
3967 * remote-eb.c: Remove newline from breakpoint message we grep
3968 for. Never time out when running the user program.
3972 Wed Feb 13 15:34:40 1991 John Gilmore (gnu at cygint.cygnus.com)
3974 Roll in changes from vxgdb-5.0.1:
3976 * dbxread.c (read_dbx_symtab): If we encounter a "FORTRAN COMMON"
3977 symbol in its raw form, we are processing an unlinked ".o" file.
3978 See if the target environment has assigned it an address, using
3979 target_lookup_symbol (VxWorks does), and enter it into the symtab
3982 * tm-vxworks.h (FRAME_CHAIN, FRAME_CHAIN_VALID): Override usual
3983 68k versions for a simpler version that assumes zero FP at bottom.
3984 Fixes bug of truncated stack reports.
3986 * target.h (target_lookup_symbol): Define this routine's args
3987 and result, finally.
3989 * target.c (nosymbol): Default routine for target_lookup_symbol.
3990 (target_default): Default lookup_symbol and call_function too.
3991 (files_info): Only print has_all_memory warning if a non-dummy
3994 * remote-vx.c (vx_read_register, vx_convert_to_virtual,
3995 vx_convert_from_virtual): If target does not have floating point,
3996 zero register "values", and avoid doing cross-net conversions.
3997 (vx_lookup_symbol): Rename net_lookup_symbol, add to vectors.
3998 (vx_open): Rearrange code that attaches to target and reads
3999 symbols for all loaded modules, to work if some of the modules
4000 are not accessible. Add symbol_stub() and add_symbol_stub()
4001 as callbacks from catch_errors(). Allow connect attempt to be
4002 interrupted painlessly with ^C (FIXME, there are still some bugs
4003 if the interrupt happens during symbol reading.). Print
4004 final message with puts_filtered, since symbol messages are
4009 * main.c (catch_errors): Only print errstring if non-null.
4010 (command_loop): Avoid an ioctl per command to test ISATTY.
4012 * remote-vx.c (net_load): make static; avoid sophomoric msg.
4013 (vx_xfer_memory): Return correct result!
4014 (vx_files_info): Indicate whether target has float or not.
4015 (vx_lookup_symbol): Complain, not error, if target gone.
4016 (vx_open): Print "Connected" msg before disabling immediate-quit.
4017 [FIXME: lookup_symbol and vx_open changes need testing.]
4019 target.c, remote-eb.c, inftarg.c, am29k-opcode.h, target.h,
4020 tm-29k.h, tmm-vxworks68.h, symfile.c, gdb-int.texinfo: Add
4021 contributor lines and update copyrights to 1991.
4023 Changes from an attempted H-PUX host port:
4025 * infptrace.c (PT_ATTACH, PT_DETACH): Handle HP/UX, which
4026 defines PT_ATTACH and PT_DETACH but not PT_KILL.
4027 * remote-eb.c (eb_open): Misplaced endif kills sysv H/PUX.
4028 * remote-vx.c: include <sys/time.h> for HPUX.
4029 * hp300hpux-xdep.c (fetch_core_registers): Rewrite old
4030 "core_file_command" routine to BFD regime. May not work yet.
4032 Attempted port of "gdb-3.4 Van Jacobson xgdb" to modern gdb.
4034 * xgdb.c: Replace X10 version with some VJ version.
4035 (FIXME: Its copyright assignment is not on record.)
4036 * xgdb.c: Update include files to X11R4 (Xaw crud).
4037 (xgdb_display_source, create_text_widget): fix call to
4038 get_filename_and_charpos. Rewack source window stuff for X11R4
4039 (gleaned from include files, and "nm's" of binary libraries, since
4040 I had no doc available).
4041 (append_selection, append_selection_word): Disable with FIXME
4042 since R4 changed interface here.
4043 (create_buttons): Add back the old set of buttons.
4044 (xgdb_create_window): Fix call to XtInitialize (&argc not argc).
4046 * Makefile.dist (xgdb, xgdb-init.c): Update for X11R4 on Suns.
4047 Roll VERSION to 3.94 (not yet final though).
4049 Sat Feb 9 09:46:25 1991 John Gilmore (gnu at cygint.cygnus.com)
4051 * obstack.h (obstack_ptr_grow, obstack_ptr_grow_fast,
4052 obstack_int_grow, obstack_int_grow_fast): Eliminate
4053 cast on left of assignment, which gives MIPS cc fits and is
4056 * sparc-pinsn.c (print_insn): Eliminate 'set' test, subsumed by
4057 F_ALIAS. Use printf, not fprintf, when not passing a file
4059 (compare_opcodes): Check that identical instructions have
4060 identical opcodes, complain otherwise.
4062 * sparc-opcode.h (st %fsr): Fix opcode "lose" mask. This
4063 was reported by Roland McGrath.
4064 (unimp): Only match if exactly zero instruction. (Roland)
4065 (branches and traps): Generate all variations of these
4066 instructions with macros, based on a single call that defines
4067 each condition name and its binary representation.
4068 (set): Turn on alias bit, to avoid test in sparc-pinsn.c.
4070 * valprint.c (val_print_fields): Take, and use, format parameter.
4071 This means that "p/x struct" again prints the elements in the
4072 desired format. Changed callers.
4074 * stack.c (frame_info): Use filtered output, and indicate wrap
4075 points. Remove kludgy formatting designed to avoid line wrap.
4077 * utils.c (wrap_here): If the line is already full (because
4078 we had printed a long indent or long wrapped string), do an
4079 immediate newline-and-indent.
4081 * m68k-pinsn.c (print_insn_arg): Bugfix from
4082 ntmtv!thompson@ames.arc.nasa.gov (Mike Thompson): 'bkpt #0'
4083 instruction is incorrectly disassembled as bkpt #8.
4085 * dbxread.c (end_psymtab): Bugfix from Peter Schauer
4086 <pesrem@regent.e-technik.tu-muenchen.de>: If you want to set a
4087 breakpoint in a *.y file gdb will say Reading in symbols for *.y...
4088 and then will dump core (sometimes). I traced it back to an
4089 uninitialized symfile_name in psymtab_to_symtab.
4090 (const_vol_complaint): Add quotes to message.
4091 (define_symbol): Only believe line number if gcc_compiled.
4092 Avoid allocating symbol if we will not return it.
4094 Add target strata support so that newly established targets go
4095 into their right place in the target stack (e.g. a new exec file
4096 doesn't wipe out the ability to access the running process).
4098 * target.h, core.c, exec.c, inftarg.c, remote-eb.c,
4099 remote-nindy.c, remote-vx.c, remote.c, target.c: Add to_stratum
4100 and initialize it properly in all the targets.
4102 * target.h: Document strata. Change return type of push_target.
4104 * target.c (nomemory): new function for dummy memory access.
4105 (tcomplain): Rename complain, now also used in symfile.c.
4106 (push_target): Push targets within strata. New return value shows
4107 whether new target is on top of stack or not. Always keep dummy
4109 (target_files_info): Ignore dummy target.
4111 * core.c (core_open): Warn user, and skip accessing file, if the
4112 core target is not the topmost target in the stack.
4113 * remote-nindy.c (nindy_create_inferior): Avoid unpush_target, now
4116 * remote-vx.c: Remove vx_prepare_to_store from vxworks memory
4117 target_ops, it doesn't belong there since we have no regs there.
4118 Change name of target from machine => memory to clarify.
4120 Thu Feb 7 16:32:09 1991 John Gilmore (gnu at spiff.cygnus.com)
4122 * Freeze version 3.93 for release.
4124 * Makefile.dist: Handle vx-share and nindy-share subdirs
4125 properly when building gdb.tar.Z.
4127 * symtab.c: lint; add no_symtab_msg to consolidate the messages
4128 printed in various places, so I could change just one copy.
4130 * dbxread.c, coffread.c: Change references to bfd->iostream
4131 to cast to FILE *, now that BFD avoids needing types defined
4132 in other header files.
4134 Tue Feb 5 21:39:35 1991 John Gilmore (gnu at cygint.cygnus.com)
4136 * command.c, dbxread.c, expprint.c, infcmd.c, infptrace.c,
4137 infrun.c, printcmd.c, remote-nindy.c, source.c, sparc-tdep.c,
4138 sparc-xdep.c, symfile.h, symmisc.c, utils.c, valprint.c: Lint
4139 (actually gcc -Wall).
4141 * dbxread.c: Remove first_global_sym, last_global_sym, since
4142 they are never referenced.
4144 * defs.h (baud_rate): Declare.
4145 main.c: Define it, and add the -b option to set it.
4147 * gdb-int.texinfo: Add text on how to define a new host or target
4148 architecture, prompted by Per Bothner's questions about MIPS
4151 * gdb.texinfo: Document "complaints". Change doc of -q since
4152 gdb no longer prints the copyright and blurb if you specify a file
4153 name to be debugged (just like Emacs). Add doc for Nindy-specific
4154 command line flags for specifying target serial port and such.
4155 Update copyright to 1991.
4157 * gdbcore.h: Remove a large mass of now-useless crud, since BFD
4158 has taken over for us the job of ripping up executable files. The
4159 crud caused Per Bothner's port to not compile.
4161 * infrun.c (normal_stop): Avoid printing "Program exited
4162 normally" if we are in batch mode. This allows a GDB which
4163 executes a program on a target system, to behave like a Unix
4164 command (input from stdin, output to stdout, no extraneous
4167 * main.c (main): Allow additional machine-dependent command line
4168 options to be specified with the ADDITIONAL_OPTIONS,
4169 ADDITIONAL_OPTION_CASES, ADDITIONAL_OPTION_HELP, and
4170 ADDITIONAL_OPTION_HANDLER macros. Also allow machine-dependent
4171 processing to occur just before the main loop with
4172 BEFORE_MAIN_LOOP_HOOK.
4173 (main): If a "core file" argument is specified, and it is not a
4174 core file, try it as a process ID to attach.
4175 (symbol_completion_function): Attempt to cope with
4176 "show screen-" TAB, not very successfully. This needs more work,
4178 (batch_file): New function, returns whether we are reading
4179 commands from an interactive tty on stdin, or from somewhere else.
4180 Called by normal_stop since it doesn't get from_tty passed down
4181 to it like many commands do.
4183 * remote-nindy.c: Handle command line options for nindy
4185 (nindy_before_main_loop): Prompt user for tty name if they
4186 don't specify it before getting to the interactive command loop.
4188 * tm-i960.c: Add ADDITIONAL_OPTIONS, etc, to handle -O, -brk,
4189 and -r command line options. Also add hook before main loop
4190 to make it easy to specify a tty.
4192 * TODO: More things to do, one done.
4194 Mon Feb 4 23:57:39 1991 John Gilmore and Mike Tiemann (at cygint.cygnus.com)
4196 * dbxread.c: Make complaint() calls pass pointer, not struct.
4197 Add complaints about badly formatted C++ type information
4198 (const/volatile indicator, and parse errors resulting in
4199 error_type). Fix C++ virtual member fn comment.
4200 (read_struct_type): Avoid bumping pointer if we got a parse
4201 error; this prevents our walking beyond the end of a string.
4202 Terminate loop on null char as well as semicolon.
4203 (process_one_symbol): Fix the LBRAC fix so that it uses the
4204 last previous SLINE, FUN, or SO record's PC address. C++ debug
4205 symbols did not have SLINE records in a useful order compared
4206 to the LBRAC records.
4207 (define_symbol): Handle "catch" records.
4209 * symtab.c (check_stub_type): Added new complain
4210 `stub_noname_complain' and added a consistency check to
4211 keep the debugger from crashing when finishing from an
4212 exception frame. A real fix will be needed later.
4214 Sat Feb 2 10:43:05 1991 John Gilmore (gnu at cygint.cygnus.com)
4216 * infcmd.c (attach_command): Make global.
4218 * Makefile.dist (REMOTE_OBS): Make these compile by default,
4219 but make them easy to comment out. Perhaps later they should
4220 be enabled by what CPU you configure for? FIXME.
4221 (VERSION): Roll to 3.93.
4222 (pinsn.o): Remove rule for obsolete file.
4223 (dbxread.o,coffread.o,mipsread.o): Use ${srcdir} explicitly.
4225 Run down a problem that manifested by printing the wrong function
4226 name in stack traces of read_ofile_symtab. Turned out that the
4227 problem was the SunOS 4.1.1 (and previous) C compiler outputs
4228 the LBRAC symbol with an address in the *data* segment, which
4229 blew our binary search through the blocks.
4231 * dbxread.c: Use the complain() facility consistently to bitch
4232 about problems in the symbol file we are reading.
4233 (finish_block): Add code to check the nesting of the blocks;
4234 complain and Procrust them to fit if wrong.
4235 (make_blockvector): Check the order of the blocks, complain
4236 [but don't cope] if wrong.
4237 (process_one_symbol): ifndef SUN_FIXED_LBRAC_BUG, check LBRAC
4238 symbols to be sure their PC value is greater than the last SLINE
4239 (line number) symbol we've seen, complaining and adopting the
4240 SLINE PC value if wrong.
4242 * symfile.h (struct complaint, complaint_root, complain,
4243 clear_complaints): Add.
4244 * symfile.c (complain, complaint_root, clear_complaints): Add
4245 facility to deal with non-fatal complaints and to regularize their
4247 (symbol_file_add): Clear complaint counters to allow new complaints.
4248 (initialize_symfile): Add 'set complaints' and 'show complaints'.
4250 * dbxread.c (dbx_symfile_read): Remember the address and size
4251 of the string table for the main symbol file, so we won't read it
4253 (dbx_psymtab_to_symtab): Fix the check for main symbol file,
4254 to avoid reading the string table yet again. Lint.
4255 (throughout): Improve filtered output, including word wrap.
4256 (read_range_type): Improve Bothner's fix to handle other types too.
4258 * utils.c: Improve line wrap implementation. Handle unlimited
4259 width by making chars_per_line unsigned.
4260 (puts_filtered): New, easy, function.
4262 * defs.h (puts_filtered): add.
4264 * mipsread.c (compare_symbols, sort_symtab): Remove these fns,
4265 call the identical sort_symtab_syms() in symfile.c instead.
4267 * expread.y: Suggest the `file' command rather than `symbol-file'.
4269 * command.h (enum var_types): Add zinteger for seroable
4271 * command.c (do_setshow_command): Handle var_zinteger. Restructure
4272 nested if's into a switch.
4274 * breakpoint.c (bpstat_print): If bpstat "print" flag is not set,
4275 we did not stop because of a breakpoint (it must have been for
4276 some other reason, like a "stepi"), so don't print anything.
4278 * symtab.c: Include <sys/types.h> all the time. Now that BFD
4279 doesn't include <sys/types.h>, old SunOS's require it for
4282 Sat Feb 2 10:39:15 1991 Per Bothner (bothner@cs.wisc.edu)
4284 A test port of gdb-3.92.6 to the Sony NEWS.
4287 Don't normally link in remote- or vx stuff.
4288 Some of it doesn't compile, and it wastes space for 99% of the users.
4289 Remove reference to no-longer-used HAVE_VPRINTF.
4290 Fixed BFD_DEP typo to BFD_DIR.
4292 Fix cast in arg to bfd_h_getlong.
4293 Make char *prefix be const.
4294 Fix how certain range types are mapped into builtin unsigned int types.
4296 Remove 2 #includes. They cause errors (on Sony, at least),
4297 and aren't needed (they wern't in earlier versions).
4299 print_address_symbolic should never demangle labels
4300 (since it prints *assembler-level* labels).
4302 [This was superseded by the change to printcmd below.]
4305 Add some "volatile" return types to avoid warnings.
4306 If MISSING_VPRINTF add vprintf function and not just macro
4307 (since vprintf is used in printcmd.c).
4309 Unless __GNUC__, use obstack_grow instead of obstack_ptr_grow.
4310 (The latter isn't grokked by some PCC-based compilers.)
4312 [This change is in abeyance, we prefer to fix obstack_ptr_grow.]
4314 Make chunk size of dont_print_obstack 32*4 instead of default 4096.
4315 * nindy-share/coffstrip.c
4316 Added some forward declarations (otherwise, gcc complains
4317 about implicit extern redefined as static).
4319 Sun Jan 20 02:38:19 1991 John Gilmore (gnu at cygint.cygnus.com)
4321 Changes inspired by Per Bothner:
4322 * printcmd.c (print_address_symbolic): Take additional parameter
4323 specifying whether to demangle.
4324 (print_address): Pass in asm_demangle to control demangling.
4325 (print_address_demangle): New fn, takes explicit arg to control
4327 * utils.c: Add new vars demangle and asm_demangle, and let them
4329 (fputs_demangled): If !demangle, just print the argument.
4330 (fprint_symbol): If !demangle, just print raw symbol.
4331 * valprint.c (val_print): Call print_address_demangle rather than
4332 print_address, to cause demangling to depend on the global
4333 rather than assembler-level demangling setting.
4334 * WHATS.NEW, gdb.texinfo: Document.
4336 * main.c (show_command): Show all settings if no arg.
4337 (initialize_main): Make "info set" the same as naked "show".
4338 * command.c (cmd_show_list): Handle prefix commands in the
4339 list, and print the name of the setting as well as its English
4340 description and value.
4342 Allow gdb functions to specify where a line should wrap if it
4343 exceeds the size of a terminal line. Use it to make the output
4345 * utils.c (set_screen_width_command): New fn, mallocs a buffer
4346 of the right size when screen width changes.
4347 (set_screensize_command, screensize_info): Remove #if 0'd fns.
4348 (wrap_here): New fn, indicates a point in the output where we
4349 should wrap the line rather than just letting it overflow at a
4351 (fputs_filtered): Implement wrapping.
4352 (n_spaces): New fn, returns a pointer to N spaces.
4353 (print_spaces_filtered): Use n_spaces.
4354 * defs.h (n_spaces): Declare.
4355 * stack.c (print_frame_info): Wrap with 4-space indent after
4356 fn name and before filename and line number.
4357 * printcmd.c (print_frame_args): Wrap with 4-space indent
4358 before each argument name is printed.
4359 * valprint.c (value_print): Wrap with no indentation before
4361 (val_print_fields): Wrap with indentation relative to nesting
4362 level before each field name.
4363 (val_print): Wrap with nesting indentation before array elements.
4364 * command.c (do_setshow_command): Avoid extra newlines,
4365 wrap with 4-space indent around values printed, end with period.
4366 * WHATS.NEW, gdb.texinfo, gdb-int.texinfo: Document.
4368 * breakpoint.c (breakpoint_1): Implement addressprint for
4369 "info breakpoints" display. Change file name and line number
4370 format to " at file:nnn" rather than " (file line nnn)".
4371 * gdb.texinfo: Document.
4374 Fri Jan 18 07:21:25 1991 John Gilmore (gnu at cygint.cygnus.com)
4376 Frozen for gdb-3.92.6 release.
4378 README, WHATS.NEW: Update for 3.92.6 release.
4380 tconfig/{altos, i386v, i386v32, m88k, umax}: Eliminate
4381 coffread.o from configs since it is now built by default.
4382 tconfig/{3b1, altosgas, arm, convex, hp300bsd, hp300hpux,
4383 i386v-g, i386v32-g, isi, merlin, news, news1000, np1, pn,
4384 pyramid, symmetry, vax, vxworks68}: Eliminate dbxread.o
4385 from configs since it is now built by default.
4387 Makefile.dist: Update for release 3.92.6. Handle files that
4388 have been moved to ../include, ../getopt, or ../bfd. Add
4389 saber.suppress and tests directory. Add config.status to
4390 the release (it will say "none").
4392 coredep.c: Minor formatting fixes.
4394 These changes were made in early December but only checked in now:
4395 * nindy-share/Onindy.c, nindy-share/coffstrip.c,
4396 nindy-share/nindy.c: lint
4397 * nindy-share/nindy.c (ninStopWhy): Don't byteswap the
4398 register values coming back from the target; we store values
4399 in target byte order everywhere.
4401 Wed Jan 16 19:01:37 1991 John Gilmore (gnu at cygint.cygnus.com)
4403 * am29k-opcode.h, am29k-pinsn.c: Add 29050 opcodes.
4405 * valprint.c (cplus_val_print, val_print_fields): New functions,
4406 which print C++ objects. They conspire to avoid printing a
4407 virtual base class more than once, following all the twists and
4408 turns of C++ virtual base rules.
4409 (val_print): Call the above rather than do it by hand.
4411 * symfile.c (symbol_file_add): Only reset symfile_mtime for main
4412 symbol file, not for added files like shared libs. This really
4413 needs to be generalized to a timestamp per file.
4415 * core.c (cleanup_core): Avoid coredump if no core file.
4417 * config.gdb: Accept -host or -target in place of +host or
4420 * coffread.c (find_linenos): Avoid desupported BFD interface
4421 to line numbers. We still read them manually rather than using
4422 BFD's "generic" features.
4424 * gdbrc.tex, threecol.tex: Add GDB reference card and its
4426 Makefile.dist: Add refcard to OTHERS list for creating tar files.
4428 * Makefile.dist: Eliminate use of $< in explicit targets.
4430 * readline/Makefile: Use $< rather than $*.c, which does not
4431 include the VPATH in GNU Make.
4433 * tconfig/i960-bout, tconfig/i960-coff: These are identical
4434 copies of tconfig/i960, added for global configuration
4435 compatability. All i960 versions can read both coff and b.out.
4437 * tm-88k.h: Fix multiline macro that lacked \'s. Remove
4438 COFF_FORMAT and COFF_CHECK_X_ZEROES since these are now handled
4441 * TODO: Think of more things to do.
4443 Wed Jan 2 19:09:29 1991 John Gilmore (gnu at spiff.cygnus.com)
4445 tconfig/{am29k,i960,sun2*,sun3*,sun4*}: Eliminate config
4446 of sdb versus dbx debug symbols. Add kludge for 68881 80-bit to
4447 64-bit float conversion.
4449 tconfig/sun4, tconfig/sun3, xconfig/sun4, xconfig/sun3: Make
4450 equivalent to sun?os4 so global config works.
4452 Wed Jan 2 18:20:51 1991 John Gilmore (gnu at spiff.cygnus.com)
4454 Fix from Eberhard Mattes <mattes@azu.informatik.uni-stuttgart.de>
4456 * main.c: Only declare linesize once; declare pagesize not at
4457 all, since it is never used.
4458 (main): Clear newly allocated line before it is used.
4460 Fri Dec 28 00:13:42 1990 John Gilmore (gnu at cygint)
4462 Further stabilization for the Intel 960.
4464 * Makefile.dist: Parameterize the location of the "include"
4465 and "bfd" directories, as well as "getopt". Add symfile.c.
4466 Link in both dbxread and coffread. Fix up "make depend" to
4467 rewack the locations of include, bfd, and getopt in its output.
4469 * README: Document moving include files, improve some of
4472 * coffread.c: Move common code out to symfile.c. Change
4473 symbol_file_command style interface to use new *_symfile_init
4474 and *_symfile_read interface under BFD. Use BFD internal
4475 info to locate line table, symbols, etc.
4477 * core.c (core_fetch_registers): Rename to get_core_registers
4478 to avoid confusion with fetch_core_registers.
4479 (register_addr): Move to coredep.c, which is already machine
4480 dependent. This leaves core.c pretty clean of dependencies.
4482 * coredep.c (register_addr): Accept this routine from core.c.
4484 * dbxread.c: Move common code (with coffread.c, etc) into new
4485 symfile.c. Each psymtab now contains a pointer to the
4486 format-dependent function that knows how to read it in. Make
4488 (dbx_psymtab_to_symtab): Renamed from psymtab_to_symtab_2.
4489 (process_one_symbol): Add code to complain about a "compiler bug
4490 we muzzle here", if we actually see it.
4492 * eval.c (evaluate_subexp): Insert missing "break" statements
4493 in code that determines whether a variable is an lvalue in
4494 memory, register, or whatever. I detected this via a compiler
4495 bug in which it *almost* mashed out the whole switch statement.
4497 * gdb-int.texinfo: Add minor sections on configuring gdb for
4498 release, and about the README file.
4500 * infcmd.c (registers_info): Fix formatting somewhat. Still
4501 not as pretty as before, but it handles byte swapping.
4503 * remote-nindy.c: If data cache routines are interrupted while
4504 waiting for the remote end, be sure that any uninitialized cache
4505 blocks are on the free list, not on the valid list!
4507 * symfile.h: Flesh out this header file with all the various
4508 routines and variables that have been merged in from dbxread.c
4509 coffread.c, and symtab.c to symfile.c.
4511 * symfile.c: New file, containing code common to dbxread.c,
4512 coffread.c, and some code from symtab.c. All generic code for
4513 reading symbol files should be in here now.
4514 (unrecord_misc_function): Remove unused function.
4516 * symtab.h: Remove file-reading things to symfile.h.
4518 * symtab.c: Remove file-reading things to symfile.c.
4520 * tm-i960.h: Fix FRAME_CHAIN types; define PRINT_RANDOM_SIGNAL
4521 to decode i960 fault types.
4523 * target.h, remote.c, remote-eb.c, remote-vx.c, remote-nindy.c,
4524 target.c: Change type of the "resume" function from int to void,
4525 since its result was never used.
4527 Sat Dec 22 02:51:40 1990 John Gilmore (gnu at cygint)
4529 * main.c: Replace "stupid" with "caution"; you now "set caution
4532 * printcmd.c (print_scalar_formatted): Fix typo in 'g' format
4534 * infcmd.c (do_registers_info): Call val_print to deal with the
4535 byte order of the registers being printed. FIXME, this makes
4536 the formatting of the output uglier.
4538 * infcmd.c (wait_for_inferior): If PRINT_RANDOM_SIGNAL is
4539 defined, call it for signals the debugger doesn't itself use.
4540 The i960 uses this for more detailed fault information.
4542 * remote.c (remote_open): If arg is null, print help rather than
4545 * sparc-xdep.c (register_valid): Avoid declaring size, since
4546 various modules will think of various sizes depending on the
4547 architecture of their tm-file. FIXME, we need protection against
4548 actually entering one of those modules, which would clobber
4549 storage if not for the target architecture compiled into gdb.
4551 * stack.c (up_command, down_command): Always print the frame
4553 (up_silently_command, down_silently_command): New commands
4556 * i960-pinsn.c (reg), i960-tdep.c: Lint.
4558 * i960-tdep.c (i960_frame_chain_valid): Lookup_symbol now takes
4559 more parameters than it used to.
4561 * findvar.c (registers): Increase slop to 256 bytes, which should
4562 protect us against even most RISC machines with large register
4564 (locate_var_value): Move declaration inside related ifdef.
4566 * remote-nindy.c (): Use TIOCSETN rather than TIOCSETP
4567 throughout, to avoid throwing away buffered input from the board.
4568 (nindy_wait): Supply_register takes addr_of_value, not value.
4569 (i960_print_fault): Renamed from i80960_fault.
4570 (nindy_fetch_registers): Avoid have_regs stuff, just get them.
4571 (nindy_store_registers): Avoid regs_changed stuff, just stuff
4573 (nindy_create_inferior): Don't bother to write PC_REGNUM since
4574 we can set the PC in the call to proceed(). Unpush nindy_ops
4575 before pushing it on top, to avoid message to user. Eliminate
4576 commentary from Unix machines that just misleads here.
4577 (reset_command): Fix error message to suggest target command.
4579 Wed Dec 19 11:03:56 1990 John Gilmore (gnu at cygint)
4581 Release 3.92.5 as frozen.
4583 Stabilize the merged release...with help from lint, Saber C,
4586 Everywhere: Add include files needed to declare return types
4587 of functions called.
4589 * gdb.texinfo: Roland Pesch is documenting gdb, glory be!
4591 * breakpoint.h: Add undeclared breakpoint functions, and some
4592 functions for display handling since I couldn't think of a better
4595 * breakpoint.c (insert_breakpoints): Make code for disabling
4596 shared library bkpts more likely to work. It's used when we
4597 rerun a program and stop before the shared library has been
4599 (breakpoint_cond_eval, bpstat_stop_status): Pass arg as int,
4600 cast from pointer, so it squeezes through catch_errors.
4601 (bpstat_stop_status): Fix logic broken some time ago. We now
4602 always create a bpstat if the stop address matches a breakpoint,
4603 even if we don't stop there -- just like the old code used to do
4604 before I got my fingers into it (sigh).
4605 (breakpoint_1): Print "ignore count" after "stop only if"
4606 condition, since that's how it actually works.
4607 (mention): Handle watchpoints as well as breakpoints.
4608 (watch_command): use set_raw_breakpoint and mention to do most
4609 of the work (and initialize all the fields!). Only pass one
4610 arg to parse_c_expression, since that's all it takes.
4612 * command.c (not_just_help_class_command): Rename arg to args
4613 since we ignore "unused argument" warnings on vars named "args".
4614 inflow.c (child_terminal_info): ditto.
4615 infptrace.c (kill_inferior): ditto
4616 main.c (catch_errors, version_info, quit_command, pwd_command,
4617 source_command, dump_me_command, editing_info,
4618 set_history_size_command, set_history, show_history,
4620 stack.c (locals_info): ditto
4621 target.c (target_files_info): ditto
4622 valprint.c (set_input_radix, set_output_radix): ditto
4624 * core.c: Remove old variables for handling core and exec file
4625 sections (data_start, data_end, stack_start, stack_end,
4626 reg_stack_start, reg_stack_end, reg_stack_offset, text_start,
4627 text_end, exec_data_start, exec_data_end, text_offset,
4628 exec_data_offset, data_offset, stack_offset). They're
4629 superseded the more general build_section_table and
4631 (get_exec_file): Mention the `file' command.
4632 (read_memory_check): Rename to memory_error, and only call it
4633 in the case of an actual error.
4634 (read_memory, write_memory): call memory_error.
4635 (core_fetch_registers): Register section name is ".reg".
4637 coredep.c: Remove a bunch of crud now that all this file does
4638 is pull the registers out of a core file.
4639 (fetch_core_registers): Rewrite to actually work, I hope.
4641 dbxread.c: Use a.out.gnu.h, not system a.out, now.
4642 Replace index() with strchr(). Remove all the pre-BFD macro
4643 definitions for accessing the symbol file.
4644 (struct dbx_symfile_info): Encapsulate the information that
4645 dbx_symfile_init needs to pass to dbx_symfile_read in this
4648 (dbx_new_init, dbx_symfile_init, dbx_symfile_read,
4649 dbx_symfile_discard): Rearrange symbol file reading to divide
4650 the format-specific part from the format-independent part,
4651 leaving the format-independent part such as file name expansion
4652 and opening in symtab.c. This replaces
4653 partial_symbol_file_open and partial_symbol_file_read.
4654 Symbol_file_read, add_file, add_file_target_command,
4655 add_file_addr_command move to symtab.c. Pass an explicit
4656 "mainline" flag for when reading the main symbol table, rather
4657 than relying on the offset address to be zero or nonzero.
4659 (dbx_symfile_read): Don't allow void *'s to be printed as
4661 (SWAP_SYMBOL): Use bfd routines to byte-swap the symbols.
4662 (ADD_PSYMBOL_TO_LIST): Make the "function call rather than
4663 macro" debug version really work.
4664 (read_dbx_symtab): Remove unref'd parameter inclink.
4665 Avoid swapping N_SLINE symbols, for speed.
4666 Merge N_TEXT!N_EXT case with the other external symbol
4667 definitions' case. Add comments.
4668 (start_psymtab): Allocate the symfile name in the psymtab on
4669 the psymbol_obstack, rather than using the caller's storage.
4670 (end_psymtab): Only allocate a dependencies list if there are
4672 (psymtab_to_symtab_2): Use BFD when reopening file to read
4673 its symbols for real.
4674 (read_struct_type): Add FIXME comments where it needs work
4676 (read_huge_number): Add FIXME about overflows.
4677 (read_range_type): Add FIXME about comparing a long to 1<<32.
4679 * coffread.c: Minor changes to move things closer to the new
4680 regime with symtab.c and dbxread.c Major work is still needed
4683 * exec.c (exec_file_command): Remove old variables (see core.c
4685 (xfer_memory): If memory transfer is right at the end of a
4686 section, don't lose.
4688 * findvar.c (get_saved_register): If value is in a real
4689 register, LVAL is lval_register, not lval_memory.
4691 frame.h: Declare print_sel_frame and record_selected_frame.
4693 gdb-int.texinfo: New file, for GDB internals documentation.
4694 Very simple, unformatted doc of cleanups is there for now.
4696 gdbcore.h: Remove obsolete variables that described a.out
4697 section addresses and offsets. (See core.c above.)
4698 Declare fetch_core_registers and registers_fetched.
4700 getopt.c: Declare char *alloca(); even on SPARC.
4702 infcmd.c (run_command): Call target_kill rather than
4704 (step_command, next_command, stepi_command, nexti_command):
4705 Declare from_tty parameter even though we don't use it.
4706 (run_stack_dummy): argument BUFFER is a char array, not
4707 a pointer to REGISTER_TYPE.
4708 (finish_command): using_struct_return needed a value *,
4709 not a struct symbol *.
4711 * infptrace.c (child_xfer_memory): To avoid dependency on
4712 where sections are in memory, try PT_WRITE_D and if that fails,
4713 try PT_WRITE_I. Most Unixes don't care which you use.
4715 * infrun.c (step_resume_break_shadow): Change to array to
4716 match other breakpoint shadow storage.
4717 (clear_proceed_status): Pass address of bpstat to
4718 bpstat_clear, not the bpstat itself.
4719 (child_create_inferior): FIXME comment about if the child
4721 (start_inferior): Remove old function.
4722 (child_open): Use target_kill rather than kill_inferior.
4723 (wait_for_inferior): Ditto.
4724 (insert_step_breakpoint, remote_step_breakpoint): Use
4725 new step_resume_break_shadow.
4727 * inftarg.c (child_wait): If all child processes die,
4728 pretend that the one being waited for exited with signal 42.
4730 * main.c (command_line_input): When scanning for comments,
4731 don't coredump on unclosed quotes.
4732 (quit_command): Use target_kill rther than kill_inferior.
4733 (_initialize_main): Rename class_user from "user" to
4736 * printcmd.c (print_command_1): Initialize "fmt" if no format
4737 is specified by the user.
4738 (print_frame_args): Only add to args_printed if we are
4739 actually fetching args from the stack (avoiding undefined
4741 (_initialize_printcmd): Remove bogus \{ from string.
4743 * remote-eb.c (eb_open): Avoid coredump on no argument.
4745 * remote-nindy.c: Bring out of Intel environment into new
4746 target environment. Remove all conditional compilation on
4747 I80960. Massive hacking throughout.
4748 (nindy_xfer_inferior_memory): New routine stolen from
4750 (nindy_create_inferior): New routine pieced together, probably
4751 not quite working yet.
4752 (nindy_ops): New target_ops struct for nindy.
4754 * remote-vx.c: Use write_memory rather than target_write_memory
4755 to get error checking.
4756 (vx_add_file_command, vx_open): Use symbol_file_add rather than
4758 (vx_create_inferior): Use target_terminal_ours...
4760 * signame.c (_initialize_signame): Always initialize, since
4761 we need the table for things other than psignal.
4763 * solib.c (solib_add): Use symbol_file_add, not add_file.
4764 (solib_address): Return boolean result rather than struct
4765 pointer which nobody else knows the type of.
4767 * sparc-tdep.c, valops.c: Use write_memory rather than
4768 target_write_memory, to get error checking.
4770 * stack.c (locals_info, catch_info, args_info,
4771 get_selected_block, frame_command, up_command): Use
4772 target_has_stack, rather than have_inferior_p or
4775 * sun3-xdep.c (fetch_core_registers): Rewrite for new BFD regime.
4777 * symfile.h: New file, defining the interface between the
4778 generic and object-file-specific symbol reading code.
4780 * symtab.c: Move generic symbol-reading interface to symtab.c,
4781 from dbxread.c, coffread.c, mipsread.c, etc. Add symtab_fns
4782 table to map BFD targets to symbol-reading modules in GDB.
4783 Change index to strchr.
4784 (lookup_struct_elt_type): Use error() rather than hand-made
4785 simulations thereof.
4786 (lookup_partial_symbol): Speedup slightly when length == 0.
4787 (symbol_file_add): New function.
4788 (symbol_file_command): Call it.
4789 (symfile_open, symfile_init): New function.
4790 (add_file_target_command, add_file_addr_command): moved from
4793 * target.c (target_command): use target_kill.
4795 * target.h (target_files_info): Don't declare, never called
4798 * tm-sun2.h, tm-sun3.h (STACK_END_ADDR): Use system include
4799 files to determine stack end address.
4801 * valarith.c (value_x_binop, value_x_unop): Change error message
4802 to be more useful. Pass proper argument to value_struct_elt.
4804 * valops.c (value_assign): FIXME comment that long long
4805 bitfields will break here.
4807 * Makefile.dist: Add symfile.h, remote-nindy.c, remote-eb.c.
4808 Update `make saber_gdb' to work better.
4810 * TODO: A woman's work is never done.
4812 * cplus-dem.c, environ.c, inferior.h, infrun.c, inftarg.c,
4813 main.c, obstack.c, printcmd.c, remote-eb.c, remote-nindy.c,
4814 remote-vx.c, remote.c, solib.c, source.c, sparc-pinsn.c,
4815 sparc-tdep.c, sparc-xdep.c, symmisc.c, symtab.c, symtab.h
4816 target.c, terminal.h, tm-sparc.h, tm-sunos.h, utils.c,
4817 valops.c, valprint.c, exec.c: Lint.
4820 Wed Dec 12 23:44:15 1990 John Gilmore (gnu at cygnus.com)
4822 Continuing Intel 960 port merge of GDB.
4824 * Makefile.dist: Merge i960 "nindy-share" files. Rename
4825 malloc.h to gmalloc.h to avoid name conflicts in /usr/include.
4826 Don't ship gdb.dvi in tar file. Link gdb with init.o, not init.c.
4827 Wack over "make depend" so it handles files in subdirectories
4828 vx-share, nindy-share, bfd, and in the current directory.
4830 * blockframe.c (get_prev_frame_info): Remove fatal error
4831 if stack not defined.
4833 * core.c (core_open, core_detach): New functions that handle
4834 the old "core-file" command as "target core" and "detach" instead.
4835 (core_file_command): Call them.
4836 (core_xfer_memory): Use common routine xfer_memory.
4838 * dbxread.c: Include a.out.gnu.h, not system a.out.h.
4839 dbxread now uses bfd for everything but symbol reading itself.
4840 BFD internals are used to drag out the relevant file offsets.
4841 (partial_symbol_file_open): Change args all around for BFD.
4843 * symtab.c: Rename "value" to "val" everywhere, so we can
4845 (symbol_file_command): New command, moved from dbxread.c
4846 and coffread.c. It uses BFD to read the file, then vectors
4847 based on its type, to dbx or coff symbol readers.
4848 * symtab.h: Extern a few vars for symbol_file_command.
4850 * target.h: Breakpoint takes a char * save area, not a char **.
4852 * valprint.c (val_print): When unpacking bitfields, offset
4853 the address in gdb of the value, if it is declared with a shorter
4854 type. Remove the last "runtime kludge test" of host byte order.
4856 * utils.c: Remove old my_bfd_read routine.
4858 * stack.c (frame_info): Use target_has_stack. Print program counter
4859 register's actual name rather than "pc", since it's called the
4860 "ip" (instruction pointer) on the i960 (sigh).
4862 * target.c (target_command): Add command for selecting a target
4863 type and calling its open routine. This is used for initiating
4864 communication with a particular target, in a generic way.
4866 * tm-i960.h: Update for modern gdb. Remove semicolons from
4867 various macros. Handle reading struct return convention, and
4868 error-out attempts to return structs with the "return" command.
4869 Be sure gdb doesn't think we know how to call functions in the
4872 * i960-tdep.c: Rename FRAME_CHAIN_VALID and FRAME_FIND_SAVED_REGS
4873 to i960_xxx in lower case.
4874 (arg_address): Circumvent errors due to LOC_ARG_BLOCK
4875 not being defined yet.
4877 * remote.c (remote_open): Call start_remote to initialize
4878 wait_for_inferior during open.
4879 (remote_xfer_inferior_memory): Return length written rather
4882 * remote-vx.c (target_command -> vx_open): Use new generic
4884 * remote-eb.c, inftarg.c, exec.c: ditto.
4886 * infrun.c: Fix comments.
4887 (attach_program -> child_open): Use new generic target command.
4888 (wait_for_inferior): Clear saved register values before target_wait,
4889 so target_wait can set some of them if convenient.
4891 * infptrace.c (fetch_inferior_registers, store_inferior_registers):
4892 Return success indicator, not void.
4893 (child_xfer_memory): Avoid fetching initial word if we'll
4894 overwrite it anyway.
4896 * infcmd.c (attach_command): Use new generic target open routine.
4897 (_initialize_infcmd): Update doc on attach and detach commands.
4898 (do_registers_info): Merge in a byte-order problem as a FIXME
4901 * findvar.c (find_saved_register): Avoid problem in current frame.
4902 (read_relative_register): Ditto.
4903 (write_register): Convert byte order on the way out.
4905 * exec.c (file_command): Add.
4906 (add_to_section_table, exec_command): Use new bfd_map_over_sections.
4907 (xfer_memory): Common function between core_xfer_memory and
4909 (exec_xfer_memory): Use it.
4911 * pn-opcode.h: Document that a "PN" is a Gould PowerNode.
4913 * breakpoint.c, breakpoint.h, symtab.h, value.h, frame.h, utils.c,
4914 valops.c, stack.c, target.c, sparc-xdep.c, source.c, printcmd.c,
4915 infcmd.c, i960-pinsn.c, eval.c, defs.h: lint and gcc -Wall.
4917 Sun Dec 2 16:45:06 1990 John Gilmore (gnu at cygnus.com)
4919 Merge Intel 960 port of gdb, continuing...
4921 * dbxread.c (partial_symbol_file_open, partial_symbol_file_read,
4922 symbol_file_command): Pass from_tty arg to hush 'em up.
4924 * coffread.c (symbol_file_command): Avoid output if from_tty != 1.
4925 Add magic numbers for 960 COFF format.
4927 Fri Nov 30 09:18:20 1990 John Gilmore (gnu at cygnus.com)
4929 Merge Intel 960 port of gdb, from Intel "1.2" release.

4947 More cleanup of batch mode; specifically, execute "-s", "-e", and
4948 "-se" switches as soon as they are encountered on the invocation line.
4950 Fri Apr 20 13:47:15 PDT 1990
4953 Thu Apr 19 09:54:28 PDT 1990
4954 Add 'reset' command.
4956 Wed Apr 18 09:48:07 PDT 1990
4957 After opening remote tty, wait for 1 second to go by without input
4958 from it before trying to talk to NINDY (fixes problems with the
4959 Heurikon HK80/V960E).
4961 Mon Apr 4 16:33:05 PDT 1990
4962 Some output was not being suppressed in 'batch' mode.
4964 Thu Mar 22 15:31:11 PST 1990
4965 Ask user if old symbol table should be deleted when new file is
4968 Allow user to run a program downloaded before gdb960 was brought up.
4970 Correct "exec-file" help message for i80960 context.

4980 code loaded at addresses higher than 0x7fffffff.
4982 Wed Jan 10 12:43:22 PST 1990
4983 Open remote tty for exclusive use.
4985 Fri Jan 5 12:14:42 PST 1990

4987 opcode for sysctl is 0x659
4989 Mon Oct 23 12:03:04 PDT 1989
4990 Use G960BASE and G960BIN environment variables to find 'sx' utility.
4992 Mon Oct 16 14:15:09 PDT 1989
4993 "sfr0"-"sfr31" should have been named "sf0"-"sf31"
4995 Mon Oct 2 15:56:31 PDT 1989
4997 Added 960CA disassembly support.
4999 To simplify maintenance:
5000 - eliminated use of symblic links on pinsn.c: use i960-pinsn.c
5002 - eliminated opcode.h: incorporates tables into i960-pinsn.c
5003 - moved 960-specific routines from i960-pinsn.c to i960-md.c
5004 - made disassembly interface identical to that in gdmp960.
5008 Wed Nov 28 21:32:48 1990 John Gilmore (gnu at cygint)
5010 * target.h: Allow targets to stack. Add target_has_memory,
5011 _registers, etc. Restructure memory access and "info files"
5012 to walk the target stack.
5013 * exec.c, core.c, inftarg.c, remote.c, remote-vx.c, remote-eb.c,
5014 target.c: Change tables to match target.h.
5015 * inflow.c (child_mourn_inferior): pop child_ops.
5016 (generic_mourn_inferior): Use new has_stack flag.
5017 * infptrace.c (child_xfer_memory): New memory regime.
5018 * inftarg.c (child_files_info): New "info files" regime.
5019 * remote-eb.c: New memory regime, new info files.
5020 * remote-vx.c: New memory regime, new info files. Now use
5021 separate targets for VxWorks attachment to machine, and
5022 actually running a process under VxWorks, since one has
5023 stack & execution & regs and the other doesn't.
5024 * remote.c: New memory regime, new info files.
5025 * sparc-xdep.c (fetch_core-registers): New memory regime.
5026 * target.c: New routines and support for stacked targets,
5027 new memory regime, new info files regime.
5030 Generalize section handling for an arbitrary number of sections,
5031 including use of the new BFD (binary file) library.
5032 * gdbcore.h: Add struct section_table.
5033 * exec.c (build_section_table): Iterate all sections and
5034 record what gdb needs to know about them.
5035 (exec_command): Use it.
5036 (exec_xfer_memory): Use the table.
5037 (exec_files_info): Print the table.
5038 * core.c (core_file_command, core_xfer_memory, core_files_info):
5040 * source.c (find_source_lines): Use bfd_get_mtime.
5041 * dbxread.c: Quick changes to make it compile with new BFD.
5042 * utils.c (error): Avoid using bfd_error in generic routines.
5044 * core.c (core_fetch_registers): Get from the ".regs" section of
5046 * sparc-xdep.c (fetch_core_registers): Use the .regs info.
5048 * inferior.h (attach_flag): Export.
5049 * infcmd.c (run_command): use new target_create_inferior.
5050 * infrun.c (child_create_inferior): Don't return result.
5051 * Makefile.dist (VERSION): 3.91.4.
5053 Fri Nov 23 28:15:38 1990 John Gilmore (gnu at cygint)
5055 * breakpoint.c (bpstat_num): Handle breakpoints which have
5056 since been deleted, such as temporary breakpoints.
5057 infcmd.c (program_info): ditto.
5059 * core.c (core_file_command): Display the frame where the core
5064 * remote-vx.c (target_command): Merge in target command from
5065 targ-vx.c. A few other cleanups.
5067 * TODO, Projects: Lots more stuff to do...
5069 Fri Nov 23 18:15:38 1990 John Gilmore (gnu at cygint)
5071 Massive changes to wall off the remote-debugging interface
5072 behind a function vector. The port to handle VxWorks targets
5073 is also part of this.
5075 All files: Replace references to renamed functions,
5076 remove references to remote_debugging, remove references to
5077 have_include_file, have_core_file in favor of target_has_stack,
5078 target_has_memory, etc.
5080 * Modularize the breakpoint interface.
5081 breakpoint.h (BREAKPOINT_MAX): New define sets max length of
5082 a breakpoint instruction.
5083 breakpoint.c: struct breakpoint's shadow_contents now sized as
5085 (insert_breakpoints): Vector to target to install breakpoints.
5086 (remove_breakpoints): Vector to target here too.
5087 Remove REMOTE_SA_SPARC kludges and other remote_debugging.
5088 sparc-tdep.c (single_step): Use new breakpoint interface for
5089 the single-step breakpoints.
5090 mem-break.c (memory_insert_breakpoint, memory_remove_breakpoint):
5091 New file, contains routines to insert and remove breakpoints by
5092 reading out the old contents and later replacing them. This is
5093 how ptrace breakpoints work, and many remote systems as well.
5095 * tm-vxworks68.h: New config file, overrides a few things for
5096 Wind River's preferences.
5098 * target.h: New file, for transfer vector used to talk to the
5099 inferior (child, attached, core, exec, remote, etc). All accesses
5100 to the thing being debugged should come through these vectors.
5101 target.c: New file, routines to handle transfer vector.
5102 (various files): Add transfer vectors XXX_ops for the various
5103 targets and pseudo-targets (core files, etc) we support.
5105 * breakpoint.c (bpstat_stop_status): Further explorations of
5106 watchpoints and why things don't work all the time.
5107 (bpstat_alloc): New fn to allocate a bpstat and chain it.
5109 * config.gdb: Only add "source ${srcdir}/.gdbinit" to
5110 the local gdbinit if it doesn't already have it.
5112 * core.c (core_ops): add and install.
5113 Allow core debugging without exec file.
5115 * dbxread.c (free_and_init_header_files): Merge two fns.
5116 (end_symtab): Free named symbol table when a new version comes in.
5117 (read_dbx_symtab): Relocate all kinds of symbols with base
5118 address. First step toward handling different text, data, bss
5120 (add_file_addr_command): Renamed add_file_command.
5121 (add_file_command): Vector to remote handler.
5122 Add "load" as an alias for "add-file" command.
5124 * defs.h: Allow "volatile" to be used in non-ANSI; use it for
5125 non-returning functions.
5127 * exec.c: Add exec_ops, and push it as a target when an exec
5130 * infcmd.c (run_command): Pass executable file name and arg list
5131 separately when starting an inferior. Permit "run" when no exec
5132 file is specified, for VxWorks.
5133 (detach_command): Move to child_detach in inftarg.c.
5135 * inftarg.c: New file. Unix-child-specific routines, and the
5136 child_ops structure.
5138 * inferior.h (registers): Export "registers" as the way for
5139 target dependent register handlers to find gdb's local copy of
5140 the registers. Rename "stop_after_attach" to "stop_soon_quietly"
5141 since it is now used by places that want wait_for_inferior to
5142 handle the grunge but want to see every trap from the inferior.
5144 * inflow.c (create_inferior): Pull out, and merge into infrun.c.
5145 Eliminate remote_debugging hooks in terminal handling.
5147 * infrun.c: Replace start_inferior with child_create_inferior.
5148 Move all the hair of Unix shells and ptrace idiosyncracies into
5149 child_create_inferior, so remote handlers don't have to deal.
5150 Remove running_in_shell. Rename stop_after_attach to
5151 stop_soon_quietly, and use it in a few other places where we want
5152 to just call wait_for_inferior and get control back on the first
5153 trap. trap_expected now never takes a value > 1.
5154 (init_wait_for_inferior): Initialize static vars when a new
5157 main.c (gdbinit): Add new hook for .gdbinit file name, let
5158 it be overridden by config files as GDBINIT_FILENAME.
5159 (DEFAULT_PROMPT): Add new hook for overriding (gdb) prompt.
5160 Both of these are used for VxWorks gdb.
5162 mcheck.c: rename include file "gmalloc.c" to avoid problems
5163 with system include file "malloc.c".
5165 param-no-tm.h: New include file, same as param.h but does not
5166 include the default "tm.h" file. This is used in files where
5167 the target is known, e.g. remote-eb.c or sparc-xdep.c.
5169 param.h: Now just a shell that includes tm.h and param-no-tm.h.
5171 remote-vx.c: New file, VxWorks remote debugging support. Uses
5172 RPC routines that are shared with the target system, in directory
5175 remote.c: Vectorize remote interface.
5177 source.c: Globalize source_path, and make an alias "l" for "list"
5178 since we now have the "load" command.
5180 sparc-xdep.c: Use new param-no-tm.h.
5182 symmisc.c (free_named_symtab): Add new function from Wind River.
5183 However, ifdef it out for now while we think about what it should
5186 tm-sun3.h, xm-sparc.h, xm-sun3.h, xm-symmetry.h: Move
5188 the xm- file, and change its name to CHILD_PREPARE_TO_STORE, since
5189 non-Unix-children handle this with their own code in the target
5192 Makefile.dist: Roll version to 3.92.3. Add vx-share stuff to
5193 source and target lists. Add vx-share to default list of include
5194 directories. Add new files to src and target lists: mem-break,
5195 target, inftarg, remote-eb, remote-vx, targ-vx. Be sure the
5196 ${srcdir} versions of munch and createtags are used.
5198 * valops.c (find_function_addr): Split out of call_function.
5199 (call_function_by_hand): Rename call_function; this function
5200 calls functions in the target by laboriously patching the target
5201 word-by-word with the right stack, args, regs, etc.
5204 Mon Nov 5 17:29:10 1990 John Gilmore (gnu at cygint)
5206 Handle AMD 29000 a bit better.
5208 * remote-eb.c (readchar): Mask received char log to make it readable.
5209 (remote_start): Pass arguments down to executing program.
5210 Make startaddr unsigned.
5211 infrun.c (start_inferior): Accept args, pass them to
5213 infcmd.c (run_command): Pass args down to start_inferior.
5215 * tconfig/am29k-aout, tconfig/am29k-coff: New files specifying
5216 the target object file format.
5217 tm-29k.h: Pay heed to COFF_ENCAPSULATE.
5219 * am29k-pinsn.c (print_insn): Print 0x on hex numbers in disassembly.
5220 am29k-tdep.c (examine_prologue): Better checking of function prefixes.
5222 Sun Oct 7 18:20:45 1990 John Gilmore (gnu at cygint)
5224 * Makefile.dist (VERSION): Roll version to 3.91.9 and freeze.
5225 * TODO: We did a few things, we have more to do though.
5227 * xm-sparc.h (CLEAR_DEFERRED_STORES): Define.
5228 * inflow.c (inferior_died): Clear deferred stores.
5230 * Debug problems with dummy frames and calls to the inferior.
5231 * tm-sparc.h (PUSH_DUMMY_FRAME, POP_FRAME): Move to sparc-tdep.c.
5232 * sparc-tdep.c (do_restore_insn): Simplify.
5233 (sparc_frame_find_saved_regs): Simplify and fix what we find.
5234 (sparc_push_dummy_frame): Simplify and fix what we push.
5235 (sparc_pop_frame): Slightly more hair here, deciding whether
5236 we are restoring a saved PC or returning to a return address in %i7.
5237 * sparc-xdep.c (read_inferior_registers): Debug if valid reg is read.
5239 * utils.c (xmalloc, xrealloc): Return type depends on __STDC__.
5240 * symtab.h (xmalloc): ditto, for obstack_chunk_alloc.
5241 * obstack.h (chunkfun): ditto.
5242 * defs.h (xmalloc, xrealloc): ditto
5244 * utils.c (quit): Grab the terminal from the child if necessary.
5246 * inflow.c (term_status_command): Rename to term_info, change
5249 * sparc-pinsn.c (print_insn): Disassembly prefers real instructions.
5250 (is_delayed_branch): Speed up.
5251 * sparc-opcode.h: Add ALIAS bit to aliases. Fix up opcode tables.
5252 Still missing some float ops, and needs testing.
5254 * Support for input and output radixes other than base 10
5255 * defs.h (input_radix, output_radix): Declare.
5256 * expread.y (yyparse, parse_number): Handle changes of input
5257 radix, and ambiguous names-or-numbers in radixes >10.
5258 * printcmd.c (print_scalar_formatted): Print formatted hex
5259 numbers in varying column widths.
5260 * valprint.c (val_print): Use output_format to print scalar ints.
5261 (set_input_radix, set_output_radix, set_radix): Create.
5262 (set_output_radix): Set output_format from output_radix.
5263 (_initialize_valprint): add `set radix' but leave the others off.
5265 * main.c (execute_command): Let stupid questions be turned off.
5266 (_initialize_main): Handle "set stupidity", etc.
5268 * main.c, inflow.c, inferior.h, frame.h, command.c, defs.h,
5269 sparc-pinsn.c, sparc-xdep.c, value.h, valops.c, values.c: Lint.
5271 Tue Oct 2 11:20:02 1990 John Gilmore (gnu at cygint)
5273 * TODO, Makefile.dist, ChangeLog: Freeze for 3.91.8 release.
5274 bfd stuff is still screwed up, but with some manual work, it
5277 * breakpoint.c (bpstat_do_actions): Start over if a command
5278 proceeds the inferior, since the inferior will have stopped and
5279 will need to have its new stop-actions taken care of.
5281 * dbxread.c (read_struct_type): Expression gives Sun3 4.0.3
5282 compiler fits, simplify it.
5284 * gdb.texinfo (directory command): Doc new dir command.
5285 source.c (directory_command): "dir" now puts things on the front
5286 of the path, moves dups up front, and handles multiple names
5287 on the command line, inserting each one in order. It also
5288 blows away cached line and full_filename info.
5290 * stack.c (backtrace_command): Skip "more stack frames follow"
5293 * Change #ifndef HAVE_VPRINTF to #define MISSING_VPRINTF in
5294 xm-convex.h, xm-hp300bsd.h, xm-isi.h, xm-merlin.h, xm-news.h,
5295 xm-np1.h, xm-pn.h, xm-pyr.h, xm-symmetry.h, xm-umax.h, xm-vax.h.
5296 The only odd one was Gould NP1, which had defined vprintf to
5299 * Merge Ted Goldstein <tedg@Eng.sun.com>'s changes for epoch.
5300 printcmd.c (print_command_1): Pass 'inspect' flag down as a global
5301 variable, inspect_it.
5302 valprint.c (print_string, val_print): Use the global inspect_it
5303 to indicate whether to print in Epoch style or normal style.
5305 Mon Oct 1 23:55:26 1990 John Gilmore (gnu at cygint)
5307 * printcmd.c (call_command): add an alias for the "print" command
5308 which runs expressions and doesn't print the result if void.
5309 (print_command_1): implement it.
5311 * command.c: Remove #if 0'd code. Initialize all the fields
5312 in add_cmd (). Rename do_nothing_command to
5313 not_just_help_class_command, and make it externally visible.
5314 command.h: add user_commands to struct.
5315 * main.c (define_command): Don't overload c->function with a char
5316 string as well as a function pointer.
5318 * eval.c (evaluate_subexp): Reinstall tiemann changes to
5319 calling convention of value_struct_elt () that got dropped in
5322 * tm-sparc.h (FRAME_FIND_SAVED_REGS): move to sparc-xdep.c.
5323 sparc-tdep.c (sparc_frame_find_saved_regs): ditto.
5325 * tm-sparc.h (POP_FRAME): replace some constants with defines.
5327 * sparc-xdep.c (store_inferior_registers): defer stores to regs
5328 until a good time (e.g. when we are about to run the child),
5329 saving ptrace calls.
5330 * infrun.c (proceed): handle DO_DEFERRED_STORES.
5331 * tm-sparc.h: define DO_DEFERRED_STORES.
5333 * sparc-xdep.c (store_inferior_registers): when storing float
5334 registers, don't store stack regs too. When storing the SP,
5335 however, DO store the stack regs too. This fixes a bug in which
5336 the dummy frame is not recognized when a call_function finishes,
5337 because its frame pointer (in the stack regs) was never
5339 (read_inferior_registers): Mark WIM and TBR and FPS and CPS valid
5340 even though we don't know how to read them from an inferior.
5341 valops.c (call_function): Comment about storing SP.
5343 * infrun.c (save_inferior_status): Save away the original bpstat
5344 chain so it can be restored later. Install the copied version for
5345 use by whoever saved the status. It will be blow away by
5346 restore_inferior_status, and the original chain restored. This is
5347 important for people who have pointers into the original.
5349 * breakpoint.c, command.h, copying.awk, dbxread.c, defs.h,
5350 findvar.c, frame.h, obstack.h, obstack.c, inflow.c, value.h,
5351 main.c, printcmd.c, sparc-tdep.c, symtab.c, valprint.c: lint
5354 Fri Sep 28 20:32:46 1990 John Gilmore (gnu at cygnus.com)
5356 * Makefile.dist: Roll version to 3.91.8. Add bfd.h and bfdconfig.h
5357 temporarily to the makefile. Add am29k-opcode.h and WHATS.NEW.
5358 Add stuff.c and kdb-start.c to the OTHERS list for tar files.
5360 Fri Sep 28 19:12:12 1990 John Gilmore (gnu at cygint)
5362 * Merge Mike Tiemann's multiple inheritance changes from Sun.
5363 Store the baseclasses in a type struct starting from array element
5364 0 rather than from the unusual array element 1.
5366 dbxread.c: the above.
5367 (virtual_context): Add
5368 Read new debug information about which virtual function table
5369 a virtual function is from, and store it in fn_field.fcontext.
5371 symtab.h: Add fcontextt. Fix baseclass indices. Typo in
5372 TYPE_FN_FIELD_STATIC_P.
5374 symtab.c: the above.
5375 valops.c: the above. Handle pointer casts of object *'s.
5376 (search_struct_method): Add.
5377 (value_struct_elt): First arg is now a pointer to a value, and is
5380 valprint.c: the above.
5381 values.c (value_virtual_fn_field): Add type arg. Handle
5382 offsetting to the proper object when calling virtual fns.
5384 (baseclass_addr): Add valuep arg.
5386 * README: Document the current state of BFD config (missing).
5387 * TODO, ChangeLog, Makefile.dist: Roll version.
5388 * WHATS.NEW: Add summary of changes since 3.5.
5390 Thu Sep 27 16:23:12 1990 John Gilmore (gnu at cygint)
5392 * dbxread.c (read_struct_type): Clear bit vectors whenever
5394 symtab.c (B_CLRALL): define.
5396 * tm-sparc.h (STORE_RETURN_VALUE): Avoid clobbering types by
5397 using == rather than =. Huh... This fixes the dreaded problem
5398 wherein builtin_type_int becomes TYPE_CODE_FLT.
5400 * core.c (info_files): Show the inferior pid.
5402 * config.gdb: Avoid putting "dir" command into .gdbinit. GDB
5403 already knows how to look in the source directory.
5405 * Remove psymtab hair from many places. Remove duplicated code
5406 for searching symbol tables. Hide psymtabs from most places.
5407 Make it fast to get from a psymtab to its symtab.
5409 blockframe.c (blockvector_for_pc): Remove psymtab hair.
5410 coffread.c (psymtab_to_symtab): Rename to psymtab_to_symtab2.
5411 mipsread.c (psymtab_to_symtab): Rename to psymtab_to_symtab2.
5412 dbxread.c: export psymtab_to_symtab, make it work if called N times.
5413 (psymtab_to_symtab): Rename to psymtab_to_symtab2. Initialize
5414 new symtab completely. New psymtabs get symtab pointer
5415 initialized to zero. Remove MI warning printf.
5416 symtab.h: Comments. Add psymtab to symtab pointer.
5417 (PSYMTAB_TO_SYMTAB): New macro.
5418 symtab.c: use PSYMTAB_TO_SYMTAB. Add psymtab_to_symtab and export it.
5419 source.c: use PSYMTAB_TO_SYMTAB. Remove symtab version and
5421 stack.c (backtrace_command): Avoid pre-pass to read symbols, if
5423 (print_frame_info): Avoid special-casing symbols that have not yet
5426 * source.c (open_source_file): Quick path if we have already
5427 located the source file by its full name.
5429 * symtab.c (lookup_symbol): Use find_pc_symtab rather than
5430 find_pc_psymtab. When a name is found in the misc function
5431 vector, search the symbol table for its mangled name, not the
5432 name that the user typed.
5434 * bfd.h: Fix missing comment terminators, make #endifs match.
5436 * valarith.c (value_less): Handle unsigned int comparisons.
5437 Add FIXME about pointer compares, which assume host and target
5438 pointers are the same.
5440 * command.c (do_nothing_command): lint
5441 dbxread.c: lint. Remove sort_syms. Document C++ visibility info,
5442 fix comments on debug symbol format for visibility. Actually set
5443 visibility of symbols.
5444 main.c (echo_command): lint; use <readline/history.h>.
5445 tm-sparc.h (FRAME_FIND_SAVED_REGS): lint
5446 obstack.h (_obstack_blank): Rearrange pointer math to avoid
5447 pointing past end of allocated memory; saber complains.
5448 obstack.h: Declare the external functions that we use.
5449 valarith.h: use <string.h>
5450 solib.c (solib_add): lint.
5452 Fri Sep 21 17:05:19 1990 John Gilmore (gnu at cygint)
5454 * main.c (initialize_main): Default info_verbose to off, now that
5455 symbol reading is fast.
5456 (quit_command): Avoid clobbering exec_bfd while quitting.
5458 * Initial BFD (binary file diddling library) merger:
5459 coffread.c: Change AOUTHDR to struct exe_hdr.
5461 core.c: initialize initialized data at compile time.
5462 (core_file_command): Move from coredep.c, convert to bfd.
5463 (xfer_core_file): Convert to bfd.
5464 exec.c (exec_file_command): use bfd routines.
5466 mips-tdep.c: Remove exec_file_command and friends.
5469 * coredep.c: (fetch_core_registers) Convert core_file_command to
5470 fetch_core_registers.
5471 mips-xdep.c, sparc-xdep.c, sun3-xdep.c: ditto.
5473 * utils.c: (error): Bogus crap, FIXME, to print bfd errors.
5474 (my_bfd_read): More bogosity, which I don't think we call.
5475 (program_name): Remove this atrocity asap!
5477 Wed Sep 19 13:36:41 1990 John Gilmore (gnu at cygint)
5480 values.c: allocate_repeat_value was not clearing the
5481 optimized_out field.
5482 (value_static_field): minor stylistic fix (wrong macro was used).
5483 valops.c (value_struct_elt_for_address): didn't work for C++
5486 * signame.c (_initialize_signame): Initialize signal names once.
5488 * breakpoint.h, command.c, copying.awk, defs.h, environ.c,
5489 exec.c, frame.h, infcmd.c, inferior.h, main.c, munch, sun3-xdep.c,
5490 symtab.h, tm-29k.h, valprint.c, value.h, values.c: Lint.
5492 * remote-eb.c: Support user-settable baud rates on the serial port.
5494 * tm-sun3.h (PREPARE_TO_STORE): fix typo.
5496 Fri Sep 14 13:28:29 1990 John Gilmore (gnu at cygint)
5498 * tconfig/sun3os4: Remove warning about native assembler,
5499 since it also occurs in the xconfig file.
5501 * findvar.c (registers): Allocate some slop after `registers'
5502 to prevent stray accesses from trashing the next variable.
5504 * tm-68k.h (REGISTER_BYTES): Allocate the right number of bytes
5505 on the sun-3, by changing the #ifdef from `sun3' (which is not
5506 defined by cc) to `sun'. Symptom was trashed builtin_type_XXX
5507 vars, which happened to follow `registers' in the executable.
5509 * readline/history.c (history_search): Heed gcc-2's advice
5510 and parenthesize && inside ||).
5512 * am29k-opcode.h, am29k-pinsn.c, am29k-tdep.c, remote-eb.c,
5513 tm-29k.c: Insert FSF copyright headers.
5515 * remote-eb.c: Better comments.
5517 * Makefile.dist: Update to 3.91.6.
5518 * TODO: note PREPARE_TO_STORE problem.
5520 Thu Sep 13 09:52:33 1990 Jim Kingdon (kingdon at cygint)
5522 * stack.c (frame_info): Only use FRAME_FIND_SAVED_REGS if defined.
5524 * remote.c: Wrap the whole file in #if !defined (SPECIAL_REMOTE).
5526 * infrun.c (wait_for_inferior, at end): Don't set up
5527 prev_* if the inferior no longer exists.
5529 * inferior.h (CALL_DUMMY_LOCATION): New macro, to replace
5530 CANNOT_EXECUTE_STACK.
5531 valops.c (call_function): Use it.
5533 * tm-convex.h: Add CALL_DUMMY_LENGTH for use by PC_IN_CALL_DUMMY.
5535 * inferior.h (PC_IN_CALL_DUMMY): New macro.
5536 infrun.c (wait_for_inferior, 2 places): Use it.
5538 * values.c (value_being_returned): Only use
5539 EXTRACT_STRUCT_VALUE_ADDRESS if defined.
5541 * Move PREPARE_TO_STORE from xm-sun3.h to tm-sun3.h to do the
5542 right thing for remote-eb.c.
5544 * sun3-xdep.c: Remove extraneous call to remote_store_registers.
5545 * sun386-xdep.c, hp300hpux-xdep.c, sparc-xdep.c: Ditto.
5547 * blockframe.c: Put get_frame_saved_regs inside #if !defined
5548 (FRAME_FIND_SAVED_REGS).
5550 * findvar.c ({fetch,store}_registers): Check for
5551 REMOTE_{FETCH_STORE}_REGISTER macro.
5553 * findvar.c (get_saved_register): Add argument lval and
5554 change meaning of argument addr.
5555 findvar.c: Change calls to get_saved_register to reflect
5556 new calling convention.
5557 valops.c (value_assign): Use get_saved_register instead of
5558 find_saved_register.
5560 Sun Sep 2 12:40:20 1990 Jim Kingdon (kingdon at cygint.cygnus.com)
5562 * coffread.c (read_one_sym): Make temp_aux an AUXENT, not
5563 an (uninitialized) pointer to one. Use "&" when passing it
5566 Fri Aug 31 22:57:54 1990 Jim Kingdon (kingdon at cygint.cygnus.com)
5568 * coffread.c (getfilename): Use DGUX x_offset and x_name if
5571 * coffread.c (symbol_file_command): Put semicolon after
5573 Put safe_to_init_tdesc_context in #if defined (TDESC).
5574 Put #ifdef TDESCs in 1st column for non-ANSI cpp's.
5575 coffread.c: #include <sys/stat.h>.
5576 (read_coff_symtab): Typo: in_source_files -> in_source_file.
5577 Add missing ')' in check for "lc%" and friends. Remove
5579 Declare read_one_sym() at top of file.
5580 (read_file_hdr): Put in extra #ifdefs so MC68MAGIC and
5581 MC68WRMAGIC can have the same value without causing a duplicate
5584 Thu Sep 13 15:55:36 1990 John Gilmore (gnu at cygint)
5586 * Allow a Makefile to be built without building the
5587 tm and xm file links that screw up builds in subdirectories.
5588 This is done with `config.gdb none', then you can do things
5589 like `make gdb.tar.Z'.
5590 * tconfig/none: Config file for no target system
5591 * xconfig/none: Config file for no host system
5592 * config.gdb: If no TM or XM files are called out by the
5593 host or target file, don't make links for them.
5595 * cplus-dem.c: Add documentation.
5597 * dbxread.c (read_ofile_symtab): Turn a fatal error into a
5598 simple error, so the user's gdb doesn't crash due to some object
5599 file problem (e.g. somebody is rebuilding the file out from under
5602 * printcmd.c (print_address_symbolic): demangle the symbol.
5604 * Makefile.dist (OTHERS): Remove tdesc-lib because it has
5605 Motorola copyrights in it. Make "make gdb.tar.Z" work.
5606 (alldeps.mak): sort and uniq all results from this; duplicates
5607 hose gdb.tar.Z link building. Remove RCS files from
5608 tconfig and xconfig. Add config files for sun386. Add
5609 a few odd files to OTHERS and HFILES.
5611 Mon Sep 10 21:20:24 1990 John Gilmore (gnu at cygint)
5613 * Makefile.dist: Pull solib.c to tconfig/sun?os4.
5614 Roll version number to 3.91.5. Make lint work in bindir.
5616 * README: Document cross-debugging and new file structure.
5618 * blockframe.c: Lint. Include "value.h" to declare read_register.
5619 (find_pc_partial_function): remove duplicate line.
5621 * command.h: Lint. Declare error_no_arg and dont_repeat.
5623 * tm-news.h: Remove inadvertently duplicated stuff.
5625 * mipsread.c: Remove cache_pc_function stuff, now done cleanly.
5626 Clean up usage of misc_function_type. Declare some CORE_ADDRs.
5628 * config.gdb: Allow `config.gdb host target' form. Clean
5629 up previous change that printed bogus messages when you just said
5632 * core.c: #include "command.h" for lint.
5635 * main.c: Remove some casts of enums. Lint.
5642 * printcmd.c (initialize_printcmd): Fix thinko in inspect cmd.
5644 * sparc-tdep.c (isannulled): Take instruction as parameter, don't
5645 read it from memory. This will allow us to save ptrace calls
5646 eventually. Changed caller single_step too.
5648 * sparc-xdep.c (fetch_inferior_registers): Avoid reading regs
5649 that we aren't going to use, saving many ptrace calls, especially
5650 when watchpointing or single stepping. Use some #define's for
5652 (store_inferior_registers): Ditto.
5653 (core_file_command): Use some #define's for constants.
5655 * tm-sparc.h: Add #define's for some register numbers, so we
5656 can eliminate the use of random constants in sparc-xdep.c.
5658 * stack.c (frame_command, print_frame_info, up_command,
5659 down_command) Remove frame_changed, since it
5660 causes a bug and doesn't seem to do anything useful. In some
5661 places it was used as a flag, in others as a stack level (?).
5663 * utils.c: Use MISSING_VPRINTF rather than HAVE_VPRINTF, so the
5664 default is to use the portable (vprintf) version rather than the
5666 * xm-news.h (MISSING_VPRINTF): Add.
5668 * valprint.c (val_print): Demangle fancy vtbl printouts. Lint.
5670 Sat Sep 8 00:24:12 1990 John Gilmore (gnu at cygint)
5672 * Remove stuff that forces -Bstatic linking of gdb, and warnings
5673 about linking debugged programs -Bstatic in the sun?os4 config
5674 files in tconfig and xconfig subdirectories.
5676 * main.c (main): Remove unreached exit(0) now that we exit
5679 * Create TODO file for online bug list. There are too many
5680 "little" bugs to keep track of on paper.
5682 * Change Projects file to refer to bug-gdb@cygnus.com
5683 rather than kingdon@ai.
5685 Fri Sep 7 23:35:15 1990 John Gilmore (gnu at cygint)
5687 * Makefile.dist (VERSION): 3.91.4 now.
5689 * symtab.c (init_misc_bunches): Rename from init_misc_functions.
5690 (condense_misc_bunches): Add sanity check that misc_count is
5691 the same as the number of symbols in the bunch.
5693 * coffread.c: rename init_misc_bunches. Pass an argument
5694 to condense_misc_bunches (a zero).
5696 * dbxread.c (partial_symbol_file_read): Call init_misc_bunches
5697 every time we are called; don't rely on our caller to do it.
5698 (add_file): Remove call to init_misc_bunches.
5700 * mipsread.c: Only warn, don't error, if unknown symbol types.
5701 This keeps an old gdb from falling on its face if it sees newly
5702 extended symbol info. Rename init_misc_bunches.
5704 Fri Sep 7 22:58:15 1990 John Gilmore (gnu at cygint)
5706 * Merge in changes from Per Bothner for DECstations and other
5707 MIPS stuff. The rest is Bothner speaking:
5709 The next message is a merger of Alessando Forin's mips port with
5710 mine. I've tried to use my good if biased judgment to get
5711 the best of both. It *does* need testing.
5713 Some of the changes are general, *not* mips-specific.
5716 Didn't believe in little-endian bit order.
5717 There are still inconsistencies about whether flags
5718 like BITS_BIG_ENDIAN are integer (#if ...) or
5719 boolean (#ifdef ...). I tried to paper over them.
5721 dbxread.c,coffread.c,mipsread.c,symtab.c,symtab.h:
5722 Moved some misc_function code that was common to
5723 {dbx,coff,mips}read.c to symtab.c.
5724 In the process, I think I cleaned things up a bit.
5725 At the same time, moved obsavestring and obconcat to symtab.c.
5728 Removed obsolete condense_addl_misc_bunches (use
5729 condense_misc_bunches(1) instead).
5732 Needed to include <sys/dir>, at least on DECstations.
5734 valops.c, mips-tdep.c, tm-mips.h:
5735 Added PUSH_ARGUMENTS macro to support funny argument-pushing
5736 conventions (when STACK_ALIGN is insufficient).
5737 Needed on mips, where doubles need 8-byte alignment,
5738 but ints only need 4.
5741 Removed cruft that was not being used.
5742 Merged in many fixes (most from Frank Yellin, fy@lucid.com).
5745 Print $ before register-names (I think that makes things a little
5747 Never print two instructions, even if one delays.
5748 Removed hex-disassemble set_cmd. (This is not mips-specific,
5749 so I think the argument is whether it is generally worthwhile or not.
5750 I'm inclined to think not, given how easy it is to
5751 convert between radixes in gdb.)
5754 This is basically Alessando's code.
5755 It doesn't use obstacks; I changed it to use obstacks
5756 in a few minor places where using malloc causes a
5757 memory leak. (Probably, more places could/should be changed.)
5758 I added record_misc_function where it was missing.
5759 In symbol_file_command and add_file_command, I tried
5760 to make the code consistent with more recent versions.
5761 Minor sylistic changes in parse_procedure.
5762 Make a .gdbinfo. psuedo-symbol point back to the real
5763 procedure symbol (using the isym field).
5766 This is basically from my port, but with a lot of details
5767 and a number of routines merged in from Alessando's version.
5768 I basically used my code "raw" backtrace (use heuristics
5769 from the actual code, rather than symbol table info) - though
5770 the idea is Alessandro's. I feel my code is a little cleaner
5771 here, particularly in being a little more flexible, such as being
5772 able to handle gcc-produced code (which it now can).
5773 It also doesn't do frame caching (which is not useful
5774 more recent gdb versions).
5775 I also used my code for push_/pop_dummy, more or less.
5776 I tried to incorporate AF's code for testing sigtramp
5777 while backtracing; I probably got it wrong.
5778 Added mips_print_register, which tries to scrunch as much
5779 information as possible on a screen...
5780 Removed the skip-prologue set_cmd. As with hex-disassemble (see
5781 under mips-pinsn.c), I don't see anything mips-specific here,
5782 and I don't see it being all that useful anyway.
5785 Added a $fp psuedo-reg distinct from $fp (nice for gcc).
5786 Use more register names (rather than hard-cases numbers).
5788 Thu Sep 6 18:33:15 1990 John Gilmore (gnu at cygint)
5790 * Hack up 3.90.11 changes:
5792 * Makefile.dist (depend): parameterize $(GCC).
5793 Add solib.c and solib.o.
5794 (readline): Fix vpath for both absolute or relative SRCDIR.
5796 * blockframe.c: Fix from Schaefer@asc.slb.com for shared libs.
5797 Also, let the part I didn't understand at least compile so
5798 I can test the rest. FIXME.
5800 * dbxread.c: Fix thinko using strcmp.
5801 (init_psymbol_list): declare static.
5802 (partial_symbol_file_open): Comment cleanups better, avoid
5803 cleaning up the string table since the caller will do that.
5804 Move the stat for mod time into symbol_file_command, temporarily.
5805 (There should be a mod time for each symbol file, eventually,
5806 to control its rereading. FIXME.)
5808 * infptrace.c (PT_WRITE_D): use same value as PT_WRITE_I for
5809 SunOS, which gives error for shared libs otherwise. (From
5810 Schaefer, probably FIXME needs work for portability.)
5812 * solib.c: Move #include "param.h" to work.
5813 Lowercase all the Uppercase Letters In the Messages.
5814 (find_solib): Clean up inferior_so_name for debug printouts.
5815 Allow no argument, to mean all shared libraries.
5817 * symmisc.c: include param.h to get CLEAR_SOLIB.
5819 Wed Sep 5 18:00:08 1990 John Gilmore (gnu at cygint)
5821 * Merge in Kingdon's changes from FSF: the diffs from 3.90.9
5822 to 3.90.11. ChangeLog entries below are from this.

5851 * Changes for Sun shared libraries:
5852 blockframe.c (find_pc_partial_function): If a non-text symbol
5853 is found, set *address = pc - FUNCTION_START_OFFSET.
5854 breakpoint.c (insert_breakpoints) [DISABLE_UNSETTABLE_BREAK]:
5855 Disable breakpoints instead of giving an error.
5856 source.c (select_source_symtab): Initialize cs_pst.
5857 symmisc.c: Call CLEAR_SOLIB if defined.
5858 symtab.h: Make text{low,high} CORE_ADDR not int.
5859 (psymtab): New field addr.
5861 dbxread.c: Move DECLARE_FILE_HEADERS outside functions.
5862 (record_misc_function): Give correct type for N_DATA symbols.
5863 (condense_misc_bunches): do "misc_function_count = j" regardless
5865 Take code which is shared between symbol_file_command and
5866 add_file_command and put it into partial_symbol_file_{open,read}.
5867 Split add_file_command into add_file_command and add_file.
5868 Make psymtab_to_symtab read in the string table if the file
5870 Two new parameters to read_dbx_symtab and start_psymtab.
5871 tm-sunos.h: New file.
5873 Tue May 22 17:43:03 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5875 * infcmd.c: Change cont_command to continue_command and "cont"

5880 * breakpoint.c (enable_breakpoint): Get value of watchpoint.
5882 * defs.h [sparc]: Use <alloca.h> regardless of __GNUC__.
5884 * values.c (USE_STRUCT_CONVENTION): Check for structures of
5885 size 1,2,4,8 rather than size < 8.
5887 * dbxread.c (dbx_lookup_type): Do f->length *= 2 as many times
5888 as necessary, not just once.
5890 * sparc-opcode.h: Add a bunch of new opcodes which Sun as supports.
5892 Thu May 17 15:04:09 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5894 * {t,x}m-sun386.h, sun386-xdep.c, {x,t}config/sun386
5896 * tm-news.h: Add CALL_DUMMY_*.
5898 * tm-68k.h: Remove duplicate comment at FRAME_FIND_SAVED_REGS.
5900 * config.gdb: In list_host, list_target, use ${i}, not $i.
5902 Tue May 15 21:27:12 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5904 * source.c (find_source_lines) [BROKEN_LARGE_ALLOCA]: Use xmalloc.
5906 * sparc-opcode.h: Change all store floating-point state register
5907 instructions to have the right match & lose fields.
5909 Sat May 5 12:39:18 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5911 * Makefile.dist: Move -I${srcdir} to GLOBAL_CFLAGS and pass
5913 config.gdb: If srcdir != ., create readline directory and
5914 copy a makefile into it.
5916 * wait.h, infrun.c: Change WRETCODE to WEXITSTATUS for
5917 consistency with POSIX.
5919 * breakpoint.c (bpstat_stop_status): Disable watchpoint
5920 when we exit its exp_valid_block.
5922 Tue Sep 4 11:46:46 1990 John Gilmore (gnu at cygint)
5924 * Makefile.dist: Bump version to 3.91.3.
5926 * Clean up handling of breakpoint commands (somewhat).
5927 Prompted by Tiemann bug report "cont 10" doesn't work any more.
5929 inferior.h: Add breakpoint_proceeded to inferior status struct
5930 and globals; save it and restore it.
5931 (clear_breakpoint_commands): Cleanup, remove old #define.
5933 infrun.c (clear_proceed_status): Set breakpoint_proceeded.
5934 (save_inferior_status, restore_inferior_status): handle it also.
5935 (proceed): Remove earlier code that set breakpoint_proceeded.
5936 It is now set only in clear_proceed_status.
5937 (clear_proceed_status): Cleanup, use bpstat_clear rather
5938 than clear_breakpoint_commands. No callers need the stop_bpstat
5939 between clear_proceed_status and proceed.
5941 infcmd.c: Add breakpoint_proceeded definition and comment.
5942 (cont_command, jump_command, signal_command): Move call to
5943 clear_proceed_status right next to call to proceed.
5945 breakpoint.c (bpstat_do_actions): Avoid clobbering our
5946 caller's argument while running down the chain of breakpoints.
5947 Use new variable "breakpoint_proceeded" to determine when
5948 a command that it executes moves the inferior past the
5950 (bpstat_clear): Handle NULL argument.
5951 (bpstat_clear_actions): Avoid useless call to
5952 breakpoint_auto_delete.
5953 (delete_breakpoint): Clean up bpstat's that are pointing to
5954 the deleted breakpoint from the stop_bpstat chain.
5955 (breakpoint_auto_delete): Simplify.
5957 * Clean up handling of EOF, error on stdin, etc. This was
5958 prompted by a network problem that caused gdb to go into an
5959 infinite loop filling up its malloc'd memory.
5961 main.c (return_to_top_level): Cleanup: call bpstat_clear_actions,
5962 not clear_breakpoints_commands, which is now gone.
5963 (main): If command_loop returns (e.g. from EOF on stdin), do
5964 a quit_command (looping back to command_loop if quit_command
5965 doesn't really quit).
5966 (command_loop): check result from command_line_input and
5967 exit if it returns NULL, rather than passing the NULL to
5969 (gdb_readline): Free malloc'd result space before returning
5972 * utils.c (query): Handle C-d to mean "yes", just as if the
5973 input was not a terminal. Also avoid infinite loop if EOF
5974 occurs in mid-input-line before newline. This allows
5975 query to be used at EOF on stdin with reasonable results.
5977 * infrun.c (proceed): Set breakpoint_proceeded.
5979 * values.c (value_as_long): Avoid infinite recursion for enums.
5980 (_initialize_values): Fix typo in help msg (kingdon).
5982 * Makefile.dist (RL_LIB): Use RL_LIB_DEP for dependencies,
5983 RL_LIB for linking. This allows -lreadline for linking
5984 and nothing for dependencies, once readline is a real library.
5986 * config.gdb: Jim Kingdon: give useful error message if the
5987 host or target type is not recognized.
5989 * defs.h (alloca): SPARC <alloca.h> does not declare alloca,
5990 it just defines it. Dumb, but deal with it.
5992 * Jim Kingdon suggests:
5993 in xconfig/sun3os4, CFLAGS should be XM_CFLAGS.
5995 Wed Aug 29 18:03:27 1990 John Gilmore (gnu at cygint)
5997 * Makefile.dist (VERSION): Bump version # to 3.91.2.
5999 * Clean up Bothner's changes.
6001 * blockframe.c (clear_pc_function_cache): New function.
6002 * blockframe.c: remake cache_pc_function_* static.
6003 * dbxread.c (symbol_file_command): remove references to
6004 cache_pc_function_* variables.
6005 * dbxread.c (read_struct_type): Use VOFFSET_STATIC.
6006 * printcmd.c: Avoid kludging a global variable (addressprint)
6007 to avoid printing the address of a string twice. Instead,
6008 pass the format letter 's' down low enough that it can be seen
6009 to avoid this problem.
6010 (print_formatted): Pass format arg to value_print.
6011 (restore_addressprint): Remove function.
6012 (do_examine): Avoid hacking addressprint, cleanups and such.
6013 (print_frame_args): Add a comment to a Bothner change.
6014 * symtab.h: define VOFFSET_STATIC and use it instead of "-1".
6015 * symmisc.c (free_all_symtabs): Call clear_pc_function_cache
6016 to wipe out the values cached in blockframe.c.
6017 * symtab.c (find_method): Add comment saying how big you must
6018 allocate to be "big enough". Per being terse again.
6019 * valprint.c (val_print): Handle format letter "s" to print
6020 strings without addresses. Add comment to vtbl printing code
6021 which casts with wild abandon. Rearrange reference-printing
6023 @0xaddr: value (print w/addressprint)
6024 value (print w/~addressprint)
6025 @0xaddr (parameter lists w/addressprint)
6026 or nothing (parameter lists w/o addressprint)
6028 Tue Aug 28 10:47:18 1990 John Gilmore (gnu at cygint)
6030 * Merge more changes from Per Bothner:
6032 Gdb's handling of TYPE_CODE_REF was so counter-C++ (and otherwise
6033 annoying) that I tried to improve it. Here are my suggestions.
6035 These patches all attempt to handle TYPE_CODE_REF (as in C++) better.
6038 Do automatic de-reference when taking the address of a reference.
6040 Don't deref_ref when printing parameter lists.
6042 More attempts at treating refernences properly.
6044 In val_print, if deref_ref==0, don't print dangling " = ".
6046 Add COERCE_REF macro, which de-references an REF.
6048 * Merge changes from Per Bothner:
6050 * Fixed (Sony news)-specific configuration problems.
6051 * Fixed other problems with using vanilla pcc and libc (enum problems;
6052 assumption that vsprintf exists).
6053 * Some major speed-ups (finc_pc_partial_function now caches a match;
6054 parsing avoids duplicate symbol_lookup calls).
6055 * Changed handling of baseclasses (no longer use baseclasses field
6056 of struct type, use the first n_baseclasses fields instead).
6057 * Various minor changes/fixes, most C++-related.
6060 Cache the most previous match from find_pc_partial_function.
6061 (Save both low and high ends of matching function's pc range.)
6062 This speeds up the loop of infrun.c:wait_for_inferior quite
6063 a bit, and makes step/next commands much zippier.
6065 Added an enum->int cast (otherwise, some compilers barf).
6067 No longer set baseclass offset to 0, since multiple
6068 inheritance now mostly works.
6069 Added a number of casts, to shut up compiler warnings
6070 (after stabs where made enums, not ints).
6071 When discarding a symbol table (in symbol_file_command),
6072 must clear the cache introduced in blockframe.c.
6073 Don't convert $vtbl_ptr_type to vtbl any more.
6074 Get rid of TYPE_BASECLASEES and baseclass_vec (see also symtab.h).
6075 Mask off sign bit emitted by g++ for virtual table offset.
6076 Set voffset to -1 (not 1) for static member functions.
6078 Changed parsing/lexing of names to avoid doing symbol lookup twice
6079 (once when lexing to determine symbol class, once for real).
6080 Now only call symbol_lookup once. Fields of 'this' win especially big.
6082 Subpress printing addr twice in the case of 'x/s addr'.
6084 lookup_basetype_type is no longer used.
6085 Add find_methods as recursive helper function to decode_line_1.
6086 This allows multiple inheritance to work.
6087 Also, once one or more matches has been found, do not look in
6088 base-classes. (Baseclass methods would be overridden, anyway.)
6090 Removed baseclasses array in struct type.
6091 Instead of using baseclasses[i], use fields[i-1].
6092 Added virtual_field_bits[i] to indicate if the i'th baseclass is virtual.
6093 Changed sign convention of voffset (previous was inconsistent).
6095 Some macros (CALL_DUMMY and relatives) were missing. Put them back.
6097 Used to assume existence of vsprintf. Re-written to not need it
6098 if HAVE_VPRINTF is undefined.
6100 typecmp was too pessimistic. Made it less so.
6102 Don't print space after address.
6103 If vtable points to a misc symbol (with 0 offset), print it,
6104 since that indicates the actual class of the object.
6105 Changed ype_print_derivation_info to use new inheritance
6106 scheme (without baseclasses vector).
6108 In value_primitive_field, fixed some bugs left over from previous set of fixes.
6109 Also, changes needed because TYPE_BASECLASSES were removed.
6111 REGISTER_U_ADDR didn't work for PC. Rewrote to use an array.
6113 Tue Aug 21 20:08:54 1990 John Gilmore (gnu at cygint)
6116 If there is no path set, and the symbols don't indicate what directory
6117 a file was compiled in, look in the current directory. But either
6118 a path or a known compilation directory will prevent this.
6121 Three independent bug fixes:
6122 * Remove the #if 0 block that breaks some stuff.
6123 * SunOS 4.1 fixed the promoted-parameter-wrong-addr bug in Sun C;
6124 adapt gdb to either SunOS 4.0.* or 4.1.
6125 * MAX_OF_TYPE and MIN_OF_TYPE thinko. By tedg@sun, I think.
6128 Instantiate the class T when looking for methods in it. (Tiemann@sun)
6131 (type_print) Demangle the name being printed.
6132 (type_print_base) Handle botched demangling without coredump (tiemann).
6135 (check_stub_method): Document routine.
6136 (tiemann) fix bug for no-arg functions
6137 Avoid clobbering beyond end of malloc'd storage.
6138 Terminate the argument list properly.
6140 Sat Aug 18 01:29:59 1990 Per Bothner (bothner@cs.wisc.edu)
6142 * Changes merged by John Gilmore:
6145 In breakpoint_1, use new print_address_symbolic instead
6146 of find_pc_partial_function. (This forces use of assembler-level
6147 addresses, and avoids misleading non-mangled source-level names.)
6149 Generalize ansi argument such that -1 means skip arglist totally.
6150 Removed global variable print_ansi_qualifiers (which made
6151 code non-reentrant), in favor of extra explicit arguments
6152 to internal routines.
6154 Add new helper function print_address_symbolic.
6155 Use find_pc_misc_function instead of find_pc_partial_function
6156 (since we want assembler-level symbols here).
6158 Print unknown function as just "f (...)", not "f (...) (...)".
6159 Use new fputs_demangled explicitly.
6161 Fixed a typing violation (problem: value.h cannot be imported
6162 without renaming many variable in this file).
6163 lookup_symbol: If no matching misc_func, look for a C++-mangled name.
6164 decode_line_1: Moved forward some never-reached code.
6165 Made decode_line_2 skip function prologues correctly.
6167 fputs_filtered should not demangle by default.
6168 Add new fputs_demangled to demangle on demand..
6170 Change value_struct_elt to use value_primitive_field (using recursive
6171 utility function search_struct_field). This allows foo.bar to work
6172 for multiple inheritance (so far only for data fields).
6173 Change check_field in the same way (recursive helper function
6174 to support multiple inheritance).
6175 (Note: there are more of these problems that I haven't fixed.
6176 Any code that says TYPE_BASECLASS (t, 1) is probably wrong.)
6177 value_of_this: 'this' symbol name is now just "this", note "$this".
6179 Don't print static members.
6180 Avoid printing "members of <type>" if there are none.
6181 Simplified type_print_derivation_info by merging duplicate code.
6182 Remove useless blank lines in type_print_base (ptype command).
6184 Added declaration of new routine value_primitive_field.
6186 Added value_primitive_field which is generalized version of
6187 value_field that can handle multiple inheritance (non-zero offsets etc).
6188 Re-implemented value_field to call value_primitive_field.
6190 Fri Aug 17 23:33:44 1990 John Gilmore (gnu at cygint)
6192 * infcmd.c -- insert else to avoid 'delete env' coredump when you
6193 delete the whole environment. Karl Berry reported the bug.
6194 * source.c - fix openp to avoid //'s in filenames, which
6195 trigger an Emacs bug causing it to not be able to find files
6196 when running gdb in a window.
6197 * dbxread.c - zap the #if 0 that botches the add-file code.
6198 It seems to work a lot better without all the code commented out.
6200 Fri Jul 20 16:58:46 1990 John Gilmore (gnu at cygnus.com)
6202 * Merge Tiemann's and Ted Goldstein's changes, detailed below,
6205 Tue Jul 17 19:34:33 1990 Ted Goldstein (tedg at golem)
6207 * Makefile - added a ${CFLAGS} to a couple of entries,
6208 added remote-sa.sparc.c
6209 * added remote.sa-sparc.c, a modification of remote.c
6210 which conducts a dialog directly with the SparcStation prom.
6211 * breakpoint.c, infrun.c, sparcdep.c added
6212 remote_insert_breakpoint(), and remote_remove_breakpoint()
6213 to breakpoint.c instead of directly writing breakpoint instructions.
6214 * sparcdep.c on remote_debugging,there is no need
6215 to remove signle step breakpoint instructions.
6216 * main.c added "-epoch" flag and "int epoch_interface" to main.c
6218 * printcmd.c - epoch interface sends lisp expressions to open up
6219 epoch windows on inspection.
6220 * valprint.c - added arrayprint, and addressprint and made adding
6221 format controls easier
6222 * wait.h added a couple of undef's because we were getting
6223 complaints about WSTOPSIG and WTERMSIG begin redefined.
6226 Wed Jul 4 05:27:51 1990 Michael Tiemann (tiemann at masham)
6228 * symtab.c (decode_line_1): Add support for handling method stubs
6229 in the type information.
6231 Tue Jul 3 09:39:18 1990 Michael Tiemann (tiemann at masham)
6233 * values.c (baseclass_addr): Run loop from INDEX+1 to
6234 N_BASECLASSES; otherwise, we can still get into a loop.
6235 @@ This should be restructured to use a cleaner search strategy.
6237 Sun Jul 1 12:28:51 1990 Michael Tiemann (tiemann at masham)
6239 * dbxread.c (define_symbol,read_type): Grok GNU C++'s new
6240 abbreviation "Tt" for tags which have the same name as their
6243 Fri Jun 29 01:03:46 1990 Michael Tiemann (tiemann at masham)
6245 * symtab.c (list_symbols): add ability to set breakpoints on all
6246 the functions which match a particular regular expression.
6248 Tue Jun 26 04:26:29 1990 Michael Tiemann (tiemann at masham)
6250 * cplus-dem.c (cplus_demangle): New parameter ANSI says whether we
6251 should print ANSI qualifiers (such as `const' and `volatile').
6252 All callers changed to call with ANSI == 1, except from
6253 `check_method_stub', which uses old-style syntax.
6255 * symseg.h (struct fn_field): Remove unneccessary `args' field.
6256 * symtab.h (TYPE_FN_FIELD_ARGS): Redefined.
6258 * values.c (check_stub_method): New function.
6260 * cplus-dem.c (do_type): Handle "long long" (encoded as 'x').
6262 * dbxread.c (read_type): Handle new GNU C++ method type stubs.
6263 * valprint (type_print_base): Ditto.
6265 * symtab.c (gdb_mangle_typename): New function.
6267 Tue Jun 5 00:18:43 1990 Michael Tiemann (tiemann at gzilla)
6269 * breakpoint.c (catch_command): New function. Provides a
6270 mechanism to set breakpoints based on catch clauses.
6271 (disable_catch): Similar, but disables breakpoints on catch
6273 (delete_catch): Similar, but deleted breakpoints on catch clauses.
6275 Sun Jun 3 22:54:08 1990 Michael Tiemann (tiemann at gzilla)
6277 * blockframe.c (blockvector_for_pc): New function.
6278 * blockframe.c (block_for_pc): Changed to call
6279 `blockvector_for_pc' and get the block itself.
6281 * stack.c (catch_info): New function. Prints info about
6282 exceptions which can be caught in the current frame.
6283 * stack.c (print_frame_label_vars): New function. Similar to
6284 `print_frame_local_vars'.
6285 * stack.c (print_block_frame_labels): Prints out labels that are
6286 defined in this frame. These labels are exceptions that can be
6289 * dbxread.c: Updated to handle N_CATCH symtab types.
6291 Thu May 3 22:10:00 1990 Michael Tiemann (tiemann at teacake)
6293 * valprint.c (everywhere): TYPE_NAME (TYPE) no longer comes in the
6294 form "struct ..." for GNU C++. Don't flush any part of TYPE_NAME
6295 when printing the type.
6297 Wed May 2 22:43:04 1990 Michael Tiemann (tiemann at teacake)
6299 * valprint.c (val_print): Use `baseclass_addr' to access the
6300 baseclasses pointed to via the derived class object at VALADDR.
6302 * values.c (baseclass_addr): New function. Casts derived pointers
6303 to baseclass pointers taking virtual baseclasses and multiple
6304 inheritance into account.
6306 Sat May 5 12:39:18 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
6310 Fri May 4 12:12:55 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
6312 * breakpoint.c (watch_command, bpstat_stop_status): Deal with
6313 exp_valid_block field correctly.
6315 * infrun.c (wait_for_inferior): When checking "don't even think
6316 about breakpoints" if stop_signal == SIGTRAP && trap_expected,
6317 also check step_resume_breakpoint.
6318 Insert breakpoints and continue (not step) if
6319 step_resume_break_address != NULL, even if another_trap.
6320 If trap_expected and we enter sigtramp, then set up a
6322 If trap_expected is set when we hit the step_resume_break,
6324 When calling resume and trap_expected says tell resume to step
6325 (2 places), also check step_resume_break_address.
6327 * infrun.c (wait_for_inferior): Don't set
6328 prev_{pc,sp,func_{start,name}} before calling wait ().
6329 Do set them after exiting loop.

6331 (start_inferior): Initialize them.
6333 Thu May 3 00:15:11 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
6335 * infrun.c (wait_for_inferior, after check for trap_expected > 1):
6336 Restore old code which distinguishes between trap_expected and
6337 running_in_shell, just make the latter take any non-TRAP signal,
6340 * values.c (allocate_value): Zero VALUE_OPTIMIZED_OUT flag.
6342 * Makefile.dist (pinsn.o): Use PINSN_CC to compile.
6343 xconfig/3b1 (CC,PINSN_CC): Define.

6356 * utils.c: Split #ifdef USG into a USG_UTILS and a QUEUE_MISSING.
6357 xm-88k.h: Define USG_UTILS.

6362 (printf_command): Add from_tty parameter.
6364 * valprint.c (value_print): Check VALUE_OPTIMIZED_OUT flag.
6366 * value.h: Add optimized_out field and change lazy field to
6367 char. Add macro VALUE_OPTIMIZED_OUT.
6369 * i386-pinsn.c: Change from Eirik Fuller to write to stream directly
6370 instead of stuffing things in buffers (oappend, etc).
6372 * breakpoint.c (bpstat_do_actions): If *BSP is set to NULL by
6373 execute_command, exit both loops.
6375 * Makefile.dist: Don't set TARGET_ARCH. Add .c.o rule.
6377 Tue May 1 17:07:23 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
6379 * Makefile.dist (RAPP_OBS, rapp),
6380 rgdb.c, rserial.c, rudp.c, serial.c, udp.c, xdep.h,
6382 m68k-xdep.c, coredep.c: Wrap in #if !defined (RDB).
6384 * valops.c (value_struct_elt), values.c (value_static_field):
6385 Change error messages to remove references to `info methods'.
6387 Tue Apr 24 10:25:10 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
6390 infrun.c (start_inferior): Add START_INFERIOR_HOOK.
6391 infcmd.c [SHIFT_INST_REGS]: New code.
6392 findvar.c (read_relative_register_raw_bytes): Return a value.
6393 infcmd.c (do_registers_info): Check value from
6394 read_relative_register_raw_bytes.
6396 * command.c (delete_cmd): Free the struct cmd_list_element(s)
6399 Mon Apr 23 10:42:21 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
6402 findvar.c (get_saved_register): New function.
6403 findvar.c: Rewrite code which called find_saved_register to
6404 call get_saved_register instead.
6406 Sun Apr 22 14:47:51 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
6408 * valprint.c (val_print): Change error message printed when
6409 the type has TYPE_FLAG_STUB set.
