1 Wed Nov 20 05:04:40 1991 Fred Fish (fnf at cygnus.com)
3 * dwarfread.c: Recognize obsolete form of AT_element_list
4 attribute still used by at least one AT&T compiler, and possibly
7 Tue Nov 19 07:53:55 1991 Fred Fish (fnf at cygnus.com)
9 * dwarfread.c (enum_type, struct_type): Ignore names invented by
10 helpful compilers for anonymous structs, unions, and enums.
12 * c-exp.y, m2-exp.y: Add defines for yymaxdepth, yy_yys, and
13 yy_yyv, so multiple parsers produced by SVR4 versions of yacc
14 can coexist in the same executable without collision.
16 * symtab.h: Add declaration for lookup_template_type() to kill
17 compiler warnings about conversions from int to pointer.
19 Mon Nov 18 17:45:18 1991 Fred Fish (fnf at cygnus.com)
21 * procfs.c: Move inclusion of defs.h to before param.h, as in
22 all the other source files that include both. This is required
23 to supply some typedefs that are used in files included by param.h.
25 * m68k-tdep.c (m68k_skip_prologue): Add generic m68k support for
26 skipping function prologues, ala the other cpu families (i386,
27 mips, m88k, etc). Add the ability to skip movm and fmovm
28 instructions in the prologues. Still needs support for profile
29 (-p compiled) prologue sequences (FIXME).
31 * tm-68k.h: Change SKIP_PROLOGUE macro to use the new generic
32 m68k prologue skipping function by default.
34 * tm-altos.h, tm-isi.h: Continue to use the old definition of
37 Mon Nov 18 15:12:45 1991 John Gilmore (gnu at cygnus.com)
39 * Makefile.in: Remove tdesc stuff, and extra blanks before colons.
40 * blockframe.c: Remove tdesc-related code. Default
42 * infrun.c: Remove tdesc-related code.
43 * m88k-tdep.c (frame_chain_combine, init_frame_pc): Remove copies
44 of defaultable things.
45 * tm-m88k.h: New file, common to all Moto 88k target configs.
46 Derived from tm-delta88.h.
47 * tm-delta88.h: Use it.
48 * xm-m88k.h: Common file for 88K hosts. Remove obsolete stuff.
49 * xm-delta88.h: Use it.
50 * tm-*.h: Remove FRAME_CHAIN_COMBINE macros, since all are
52 * coffread.c: Remove tdesc stuff.
53 * tconfig/delta88, tconfig/m88k: Remove tdesc stuff.
54 * xconfig/m88k: Rename tm-88k.h to tm-m88k.h.
56 Mon Nov 18 13:51:37 1991 Per Bothner (bothner at cygnus.com)
58 * source.c (open_source_file): If openp fails, try again
59 using just the base (non-directory) part of the filename.
60 This solves various annoying problems, such as when the
61 source was compiled with an absolute pathname - and the
62 source files have moved. Or if the source was compiled
63 using a relative pathname, it can be more convenient
64 to just specific the source directory to the dir command.
66 Mon Nov 18 00:04:41 1991 Fred Fish (fnf at cygnus.com)
68 * cplus-dem.c (munge_function_name): Add missing third arg to
69 instance of call to do_type().
71 * dwarfread.c: Changes to match new dwarf.h. Remove
72 AT_deriv_list, AT_loclist, AT_incomplete, AT_const_data,
75 Sun Nov 17 16:20:53 1991 Michael Tiemann (tiemann at rtl.cygnus.com)
77 * symtab.h (struct type): Moved C++-specific fields into new type
78 `struct cplus_struct_type'. Now takes 10% less memory. Many
80 * symtab.c (init_type): Don't set fields belonging to
81 TYPE_CPLUS_SPECIFIC unless TYPE is TYPE_CODE_STRUCT.
82 * buildsym.c (read_type): Allocate TYPE_CPLUS_SPECIFIC for
84 (read_struct_type): Ditto. Also, add comments about how we can
85 deduce TYPE_VPTR_FIELDNO from inheritance info and fieldname info.
86 * coffread.c (decode_base_type): Allocate TYPE_CPLUS_SPECIFIC for
88 (read_struct_type): Ditto.
89 * dwarfread.c (struct_type): Ditto.
91 * symtab.c (read_range_type): Don't set TYPE_MAIN_VARIANT.
92 (lookup_pointer_type): Don't use or set TYPE_MAIN_VARIANT.
93 (lookup_reference_type): Ditto.
95 * cplus-dem.c: Many changes made to handle decoding of
97 * symtab.c (gdb_mangle_name): Mangle/demangle ANSI-mangled names

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

138 gdb.z into the right place.
140 Wed Nov 13 16:45:13 1991 John Gilmore (gnu at cygnus.com)
142 Motorola 88000 port without tears, I mean without tdescs.
144 * m88k-tdep.c: Blow away all tdesc stuff.
145 Provide functions for all the frame-related macros in
146 tm-delta88.h. Adopt i960-style EXTRA_FRAME_INFO.
147 (examine_prologue, frame_find_saved_regs, skip_prologue): borrow
148 from i960-tdep.c and adapt to the function prologues on the 88k.
149 (read_next_frame_reg): Borrow from mips-tdep.c.
150 FIXME: frame_locals_address should go away.
152 * tm-delta88.h: Dump all the tdesc stuff.
153 Macros for all frame-related stuff call fns of same name.
154 Remove duplicated definitions. FP_REGNUM becomes same as
157 * xm-88k.h: Eliminate lots of library dependencies, now handled
158 in libiberty. Eliminate KDB nonsupport.
160 * doc/gdbint.texinfo: Add rudiments on frames. FIXME, add more.
163 * stack.c (frame_info): Mark frameless functions.
164 Print locals address (FIXME, remove if same).
165 * blockframe.c: Comment changes, FIXME after.
166 * coffread.c: Even without TDESC, need to zap "@" symbols.
167 Don't register for wierd format names; change the names in BFD.
169 * alloca.c, language.c, tdesc.c: Lint.
170 * tdesc.c, tdesc-lib: FIXME: remove these.
172 Tue Nov 12 19:30:22 1991 John Gilmore (gnu at cygnus.com)
174 * Makefile.in: Add tdesc library support. Fixups to lint,
177 Tue Nov 12 13:43:26 1991 Per Bothner (bothner at cygnus.com)
179 * symtab.c (decode_line_1): Remove spurious call to operator_chars.
181 Allow setting breakpoints on C++ destructors.
182 * valops.c (destructor_name_p): Don't check TYPE_HAS_DESTRUCTOR,
183 since it lies. Rely on callers to catch missing destructors.
184 * symtab.c (decode_line_1): For example (see above), here.
185 * buildsym.c, symtab.h: Remove TYPE_FLAGS_HAS{CON,DE}STRUCTOR
186 flags since they are no longer used.
188 Fixes to support C++ methods with functional parameters.
189 * c-exp.y (func_mod rule): Allow (and ignore) list of parameter
190 types in a function type.
191 * eval.c (parse_and_eval_type), value.h: New function,
192 parse_and_eval_type, is based on old code from check_stub_method.
193 But don't actually evaluate the cast, since that calls
194 value_cast(), whcih may fail. Just extract the type
195 from the parsed expression.
196 * values.c (check_stub_method): While looping through the
197 arguments, adjust depth *after* parameter has been handled.
198 Replace call and setup of parse_and_eval with new function
201 Tue Nov 12 09:40:07 1991 Fred Fish (fnf at cygnus.com)
203 * utils.c, rem-multi.shar: Remove fixed arg count version of
206 * altos-xdep.c, arm-xdep.c, coffread.c, command.c, convex-xdep.c,
207 core.c, dwarfread.c, gould-xdep.c, infcmd.c, language.c,
208 m88k-xdep.c, main.c, printcmd.c, pyr-xdep.c, source.c,
209 sun386-xdep.c, symm-xdep.c, umax-xdep.c, values.c, xcoffread.c:
210 Change all instances of use of fixed args concat() to variable
211 args concat() now located in libiberty.
213 Tue Nov 12 07:23:46 1991 John Gilmore (gnu at cygnus.com)
215 * Makefile.in: Add xcoffread.c, xcoffexec.c.
216 * xcoffread.c: New file for handling AIX mangled-coff files.
217 * xconfig/rs6000, tconfig/rs6000: New files.
218 * buildsym.c: Add hooks for xcoffread.c.
219 * rs6000-pinsn.c, rs6000-tdep.c, rs6000-xdep.c, tm-rs6000.h,
220 xm-rs6000.h, rs6k-opcode.def, rs6k-opcode.h: New files.
221 * xcoffexec.c: New file for handling AIX shared libraries.
223 Mon Nov 11 19:14:31 1991 Fred Fish (fnf at cygnus.com)
225 * core.c: Minor rewording of message to user containing name of
226 (and possibly arguments to) the program that generated a core
229 * elfread.c: Remove the register_addr() stub now that it is no
232 * procfs.c: Move misplaced #endif for ATTACH_DETACH. Add new
233 fetch_core_registers() function for core file support.

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

266 * dbxread.c: Make more errors into complaints.
267 (push_subfile, pop_subfile): Move to buildsym.c.
268 (dbx_symfile_read, dbx_symfile_init, fill_symbuf, read_dbx_symtab,
269 start_psymtab, psymtab_to_symtab_1, read_ofile_symtab,
270 dbx_psymtab_to_symtab, ): Use bfd ops, don't use file descriptor.
271 Pass objfile. Change callers.
272 (fill_symbuf, SWAP_SYMBOL): Take bfd as arg.
273 (read_dbx_symtab): Just wipe out new symbols, not all, on error.
274 (end_psymtab): Blow away psymtab if empty.

279 * buildsym.c (end_symtab): Pass objfile.
280 (dbx_lookup_type): Handle null typevector.
281 (dbx_alloc_type): Check file number, not sym number, for -1.
282 (find_symbol_in_list): Add for xcoffread.
283 (start_symtab): Default typevector is empty. Keep reusing same
285 (end_symtab): Take objfile argument and pass it to
286 allocate_symtab. Don't make a symtab if no blocks or symbols.
287 Handle empty typevector.
288 (push_context): New function for context stack nesting.
289 (read_type): Mark FIXME where we need to reintroduce type smashing.
291 * buildsym.h (pop_context): Macro, paired with push_context.
292 (subfile_stack): Move here from dbxread.c.
294 * coffread.c (end_symtab, read_coff_symtab): Take and use objfile arg.
295 (read_coff_symtab): Cleanup by freeing objfile, not all symtabs.
297 * mipsread.c (read_mips_symtab, parse_partial_symbols, parse_fdr,
298 new_psymtab, new_symtab): Take and use objfile arg.
300 * dwarfread.c (scan_compilation_units, start_psymtab,
301 process_dies, end_symtab, dwarf_build_psymtabs,
302 read_lexical_block_scope, read_func_scope, read_file_scope): Take
303 and use objfile argument.
304 (psymtab_to_symtab_1, read_ofile_symtab): Don't take or use file
305 descriptor. Use BFD internal functions instead.
306 (end_symtab): Call global allocate_symtab.
308 * elfread.c, target.c: Minor changes to accommodate objfiles.
309 * symtab.h: partial_symbol_table has no symfile_name member now.
310 (fn_fieldlists voffset): avoid non-int bitfield.
311 (struct symtab): Add objfile * and objfile_chain * of symtabs.
312 (struct partial_symtab): Add objfile * and objfile_chain * of
313 psymtabs. Remove symfile_name.
315 * symmisc.c: Lose free_all_symtabs, free_all_psymtabs.
316 (printsyms_command): Rename from print_symtabs. Add selective
317 listing if 2nd argument given. Print objfile info.
318 (printpsyms_command): Rename from print_partial_symtabs. Ditto all.
319 (printobjfiles_command): New; prints objfiles lists, and checks

322 * symfile.h, symfile.c, symtab.h: Lint
324 Fri Nov 8 23:38:48 1991 John Gilmore (gnu at cygnus.com)
326 * command.c: Include param.h.
327 * defs.h (warning_setup, warning): Declare.
328 * expprint.c (print_subexp, UNOP_MEMVAL case): Lint.
329 * inflow.c (new_tty): Use USE_O_NOCTTY #define.
330 * language.c, printcmd.c (print_scalar_formatted), signame.c,
333 Thu Nov 7 18:26:15 1991 Steve Chamberlain (sac at rtl.cygnus.com)
335 * Makefile.in: link with libiberty after libreadline, since
336 readline might want something in libiberty.
337 * m88k-xdep.c: Fixed the register offsets in the ptrace_user
338 struct for BCS 88k machines.
339 * xm-m88k.h: don't define USIZE if already defined.
340 * configure.in: Added delta88 target.
342 Thu Nov 7 04:51:19 1991 John Gilmore (gnu at cygnus.com)
344 * am29k-pinsn.c, am29k-opcode.h: Fix decoding of mtacc, dmac, fmac.
346 * tm-*.h: Remove READ_DBX_FORMAT, COFF_FORMAT, and
347 READ_MIPS_FORMAT, which have been unused since BFD. Still
348 remaining is COFF_NO_LONG_FILE_NAMES.
349 * tm-sun3.h, tm-altos.h: Remove detritus accidentally left from
350 function calling code moved to m68k-tdep.c.
352 Wed Nov 6 17:21:59 1991 John Gilmore (gnu at cygnus.com)
354 * coffread.c: Eliminate c_nsyms in favor of c_naux.
355 Complain if no auxents on .bf and .ef FCN symbols, and assume
356 lots of line numbers.
357 (init_linenos, enter_linenos): Use a sentinel at the end of the
358 read-in linenos, to make for a fast, safe loop-end test.
360 Wed Nov 6 02:54:08 1991 Steve Chamberlain (sac at cygnus.com)
362 * coffread.c (read_coff_symtab): coffread used to rely on the
363 x_sym.x_misc.x_lnsz.x_lnno field giving the # of linnos in a
364 function. Two of the formats I'm using (29k and 88k) don't seem to
365 set it. Ths patch to fcn_last_line and (enter_linenos) is an
366 attempt to use the actual size of the linno table in the file to set
367 the number of linenos to process.
369 Tue Nov 5 22:47:46 1991 Steve Chamberlain (sac at cygnus.com)
371 * Makefile.in: put a - infront of the mv y.tab.c c-exp.tab.c and
372 mv y.tab.c m2-exp.tab.c, so that if bison is used, and the files
373 are created in place, so the mv fails, then the make continues.
375 Tue Nov 5 16:47:47 1991 Per Bothner (bothner at cygnus.com)
377 Add C++ as a separate language.
378 * defs.h (enum language): Add language_cplus.
379 * dwarfread.c (end_symtab): Support language_cplus.
380 * c-exp.y: Add new struct language_defn cplus_language_defn.
381 Don't set c to be the default language (see main.c).
382 * c-exp.y (yylex): Only look for field of this if
383 language is C++. (First difference from C!)
384 * language.c: Add case branches for C++ (currently, all
385 the same as C). Also, add c++ to "usage" note for "set lang".
386 * valprint.c (typedef_print). Add case branches for C++.
387 * main.c (main): New way to set initial language: Look at
388 file extension of psymtab containing main(). (Same as we
389 do for symtabs, but avoid loading the symtab yet.)
390 * symtab.c: New routine find_main_psymtab(), used by main()
391 to set initial language.
392 * symfile.c (allocate_symtab): Move code for mapping file
393 extensions-> languages to new deduce_language_from_filename().
395 Fix a C++ problem when looking for methods in super-classes.
396 There was confusion between base and derived types.
397 * valops.c (value_fn_field): Change function interface.
398 * values.c: Use new value_fn_field interface.
400 Mon Nov 4 10:49:33 1991 Per Bothner (bothner at cygnus.com)
402 * infrun.c: Fixed typo in comment.
403 * utils.c: All the v*fprintf emulation is now in libiberty,
404 so we can get rid of some junk.
405 * xm-sun3os4.h, xm-sun4os4.h, xconfig/decstation, xconfig/i386sco,
406 xconfig/sun3os4, xconfig/sun4os4: Don`t need HAVE_STRSTR any more.
407 * m68k-pinsn.c (print_insn_arg): Support BB/BW/BL
408 type operands, as used by branch instructions.
409 * gmalloc.c: Fix prototype of memcpy.
410 * elfread.c: Comment out register_addr, since it conflicts
411 with the one in coredep.c.
412 * buildsym.h: Remove extern declarations of two functions
413 that are really static in buildsym.c.
414 * tm-mips.h: Add symbolic names for more registers.
415 * mips-xdep.c (store_inferior_registers): Use new register names.
416 * xm-mips.h: Simplify REGISTER_U_ADDR, since it is now
417 only used for core files, not ptrace. Therefore,
418 the KERNEL_U_ADDR hack is no longer needed.
419 The mapping to ptrace number is now in in mips-xdep.c.
420 * mips-xdep.c: Define REGISTER_PTRACE_ADDR (using the
421 mapping from the old REGISTER_U_ADDR), and use it
422 in {fetch,store}_inferior_registers.
423 * mipsread.c: Rename #include ecoff.h to new name coff-mips.h.
424 * mips-tdep.c (mips_push_dummy_frame, mips_pop_frame):
425 Save/restore FP regs correctly (?).
426 * dbxread.c: Remove duplicate define_symbol and type_synonym_name
427 (these had been previously moved to buildsym.c).
428 Hence, define_symbol becomes extern instead of static.
429 * buildsym.c (read_struct_type): Comment out bogus handling
430 of C++ operator methods. Minor hacking of reading of class
431 contexts. Make define_symbol non-static, so dbxread.c can call it.
433 Fri Nov 1 11:05:47 1991 John Gilmore (gnu at cygnus.com)
435 * mipsread.c (read_mips_symtab, read_the_mips_symtab): Use real
436 filename with error messages.
437 * stack.c (frame_select_command): Rename to select_frame_command
438 to avoid "fr" and "fra" having nonunique completions.
439 * symfile.c (sort_symtab_syms): Ignore sort of zero symtab *.
440 (symfile_init): Print file format name when unable to handle it.
441 (free_named_symtabs): Use BLOCKVECTOR rather than obsolete BLOCKLIST.
442 * symmisc.c (free_symtab): Only free linetable if nonzero.
443 * symtab.h: Remove obsolete BLOCKLIST macros.
445 Thu Oct 31 18:12:43 1991 Stu Grossman (grossman at cygnus.com)
447 * infrun.c (wait_for_inferior): another stepi/nexti fix. Ensure
448 that stop_step is 1 at bottom of main loop. I don't know why this
449 needs to be done, but it helps me sleep better at night.
451 Sun Oct 27 18:18:39 1991 Stu Grossman (grossman at cygnus.com)
453 * main.c (initialize_history): Read history after reading all
456 Sun Oct 27 14:09:25 1991 John Gilmore (gnu at cygnus.com)
458 * buildsym.c: Break out initial malloc sizes.
459 (record_line): Record directly in a subfile. Alloc on demand.
460 (compare_line_numbers): Add from xcoffread.c.
461 (end_symtab): New params say whether to sort pendings and
462 linetable. Patch block stabs if defined. Shrink linetable before
463 allocating the symtab.
464 * buildsym.h: Delete line_vector* and prev_line_number. Add
465 global_stabs and file_stabs for xcoffread.
466 * dbxread.c (start_subfile): Move to buildsym. Change above calls.
467 * symtab.h: LINETABLE(symtab) can now be null. Zap LINELIST.
468 * symmisc.c, symtab.c: Cope with null LINETABLEs.
470 * blockframe.c: Pass fromleaf to INIT_EXTRA_FRAME_INFO.
471 * tm-29k.h, tm-88k.h, tm-i960.h, tm-irix3.h, tm-mips.h, tm-pyr.h,
472 tm-sparc.h: Accept fromleaf parameter.
473 * c-exp.y (yyerror): Pass error message if given.
474 * configure.in: Add rs6000 host and target.
475 * inflow.c (new_tty): O_NOCTTY kludge for RS/6000.
476 * symfile.h (entry_point): Add.
478 Sat Oct 26 00:16:32 1991 John Gilmore (gnu at cygus.com)
480 * buildsym.c: New file. Breaks out symbol-table-building routines
481 from dbxread.c, so they can be shared with xcoffread.c.
482 * buildsym.h: New file. Declarations for buildsym.c users.
483 * dbxread.c: Remove large chunks into buildsym.c.
484 * Makefile.in: Add buildsym.c and buildsym.h.
486 * symfile.c (syms_from_bfd): New routine.
487 (add_symbol_file): Call it to do the real work.
488 (syms_from_bfd): Initialize entry_point before calling symfile_init.
489 * symtab.h, symfile.c, coffread.c, mipsread.c, dwarfread.c:
490 Avoid declaring or setting entry_point (symfile.h & symfile.c cope).
492 Fri Oct 25 10:58:16 1991 Mark Eichin (eichin at cygnus.com)
494 * cplus-dem.c (cplus-demangle): added support for templates, static
495 data, and the new (correct) mangling for destructors.
497 * dwarfread.c: (dwarfwarn): created a varargs version of
498 dwarfwarn, for non __STDC__ compilers.
500 * c-exp.y: (yylex): added match for "template" token.
501 (typebase): added TEMPLATE name '<' type '>' clause, for explicit
502 specification of template types.
504 * symtab.c: (lookup_template_type): new function for finding
505 templates in symbol table.
506 (type_name_no_tag): changed to explicitly check for s/u/e at the
507 beginning of the symbol - if it is a template, none of these will
508 be there (but the name will still contain spaces.)
510 Fri Oct 25 18:59:32 1991 Per Bothner (bothner at cygnus.com)
512 Various fixes to improve g++ debugging.
513 * symtab.h: Add is_const and is_volatile flags for each method.
514 These are bit fields - take their space from voffset,
515 which shrinks to 30 bits. Since voffset is now a bitfield,
516 make it unsigned for portability. This changes its interpretation
517 slightly: Static methods now have voffset 1 instead of -1,
518 and virtual offsets start at 2, not 1.
519 * symtab.c: Renamed gdb_mangle_typename to gdb_mangle_name,
520 since it now returns an entire magled method name, not just
521 the type part. This avoids some duplication.
522 It also allows us to correctly mangle const and volatile
523 methods (using the new is_const and is_volatile bit fields
525 * valprint.c (type_print_base), values.c (check_stub_method):
526 Simplify by using new gdb_mangle_name.
527 * values.c (value_headof): Fix to correctly handle single
528 inheritance (actually two fixes, either of which suffices).
529 * dbxread.c (read_struct_type): Handle const and volatile
531 * dbxread.c (read_struct_type): Yet one more place where
532 we must handle '\\' continuations.
533 * valprint.c (vtbl_ptr_name): Add final '\0'.
535 Fri Oct 25 16:06:38 1991 Stu Grossman (grossman at cygnus.com)
537 * tm-sparc.h, tm-68k.h (EXTRACT_RETURN_VALUE): fix output of
538 short return values for sparc and 68k. Patch from Paul Eggert.
540 * coffread.c, coredep.c, i386-xdep.c: install patches for
541 SysV/386 3.2 from Mauro DePalma.
543 Fri Oct 25 02:02:13 1991 John Gilmore (gnu at cygnus.com)
545 * core.c (core_file_info), exec.c (exec_file_info): Print file
546 type. Use printf_filtered.
548 * valops.c (value_fetch_lazy): Avoid 0-length fetches.
550 Thu Oct 24 23:06:40 1991 Fred Fish (fnf at cygnus.com)
552 * dwarfread.c: Add casts to remove compiler warnings.
554 * tm-3b1.h, tm-68k.h, tm-altos.h, tm-amix.h, tm-hp300bsd.h,
555 tm-hp300hpux.h, tm-isi.h, tm-news.h, tm-pn.h, tm-sun2.h,
556 tm-sun3.h: Remove locally duplicated code for calling functions
557 in the inferior. The only differences were in the specific trap
558 vectors used and whether or not an fpu was present. These are
559 now handled by appropriate definitions of BPT_VECTOR and
560 HAVE_68881 respectively. Other minor obvious cleanups.
562 * valops.c: Correct a minor misspelling.
564 * utils.c: Remove local BSD/USG hacks that are now in libiberty.
566 * dwarfread.c: Remove prototype for dwarfwarn. Does not work
569 Thu Oct 24 09:33:44 1991 John Gilmore (gnu at cygnus.com)
571 * stack.c (frame_command): Always print. Use new
572 frame_select_command to select a frame without printing.
574 * dwarfread.c: Use <varargs.h>, since <stdarg.h> is not portable.
576 Thu Oct 24 01:32:51 1991 Fred Fish (fnf at cygnus.com)
578 * dwarfread.c: New file for DWARF debugging format support.
580 * elfread.c: New file for ELF object file format support.
582 * procfs.c: New file for SVR4 /proc (process file system) support.
584 * tm-amix.h, xm-amix.h, tconfig/amix, xconfig/amix: New files for
587 * xm-svr4.h, tm-svr4.h: New files for SVR4 support.
589 * xm-m68k.h: New file for host machines with m68k cpu.
591 * Makefile.in: Add elfread.c and dwarfread.c to SFILES_MAINDIR.
592 Add elfread.o and dwarfread.o to OBS.
594 * symfile.h: Add "elf" to list of supported formats in comment.
596 * c-exp.y, defs.h, symtab.h, valprint.c: Add three new builtin
597 types to gdb, builtin_type_long_double, builtin_type_complex, and
598 builtin_type_double_complex. Add and use new TARGET_SHORT_BIT,
599 TARGET_INT_BIT, TARGET_LONG_BIT, TARGET_FLOAT_BIT,
600 TARGET_DOUBLE_BIT, TARGET_LONG_DOUBLE_BIT, TARGET_COMPLEX_BIT, and
601 TARGET_DOUBLE_COMPLEX_BIT, as the sizes in bits of the indicated
602 types on the target machine (ala the existing TARGET_LONG_LONG_BIT).
604 * infrun.c: When using SVR4 /proc interface instead of ptrace(),
605 call proc_set_exec_trap() to setup child to stop at first instruction.
607 * inftarg.c: When using SVR4 /proc interface, call proc_wait()
610 * m68k-tdep.c: Add new routines supply_gregset(), fill_gregset(),
611 supply_fpregset(), and fill_fpregset(), which are machine
612 dependent support routines for SVR4 /proc interface.
614 * utils.c: Add warning_setup() and warning(). Warning() behaves
615 the same as error() except that it returns normally rather than
616 jumping back to command level. Modules that don't want to call
617 warning() for some reason, but want to produce their own warnings,
618 can call warning_setup() to ensure compatibility with the way
619 warning() and error() deal with the terminal.
621 * symtab.c: Make internal errors produce more useful messages.
623 * tm-68k.h: Move code that is duplicated in almost every single
624 m68k based machine's configuration files to this common file.
625 Duplications in the configuration files still need to be removed
628 * infrun.c (child_create_inferior): System V versions must call
629 setpgrp() with no arguments, to comply with prototyping typically
632 * munch: Add support for SVR4 style nm output.
634 * dbxread.c, mipsread.c symmisc.c, symtab.c: Remove the object
635 file specific fields from the partial symbol table structure and
636 replace them with a pointer to private data for each different
637 flavor of object file reader to initialize appropriately.
639 Wed Oct 23 09:38:20 1991 John Gilmore (gnu at cygnus.com)
641 * xconfig/sun[34]os4: Add note about strstr botch on sunos4.0.3c
644 * mipsread.c (fixup_undef_type): New function. If a struct /
645 union / enum is defined in a header file but nowhere else used,
646 (by typedefing, pointer referencing or declaration) the mipsread code
647 builds the complete tree for the structure but leaves its code as
648 TYPE_CODE_UNDEF as it doesn't know what kind of aggregate it is.
649 Guess its type based on the details of the members.
651 Tue Oct 22 18:04:32 1991 Stu Grossman (grossman at cygnus.com)
653 * infrun.c (wait_for_inferior): Check return value from
656 Mon Oct 21 17:47:03 1991 Stu Grossman (grossman at cygnus.com)
658 * infrun.c (wait_for_inferior): fix stepi/nexti that was broken
659 by my last edit to this routine.
661 Mon Oct 21 14:27:43 1991 John Gilmore (gnu at cygnus.com)
663 * tm-sun3.h (FIX_CALL_DUMMY): problem with cross debugging.
664 FIX_CALL_DUMMY does unaligned accesses and/or forgets to byte swap
665 the values before putting them into the dummy code. (From Peter
668 Mon Oct 21 10:04:39 1991 Steve Chamberlain (steve at rtl.cygnus.com)
670 * configure.in: added ebmon target.
672 Wed Oct 16 22:49:58 1991 John Gilmore (gnu at cygnus.com)
676 * Makefile.in: Roll VERSION to 4.2.
677 * README, TODO, WHATS.NEW: Update.
679 * core.c (core_open): Improve error message for bad file.
680 Pass .reg virtual memory address to fetch_core_registers to help
681 it find the registers in the core-file header.
682 * coredep.c (fetch_core_registers): Take new argument, use it,
683 and pass it to register_addr to locate the block of registers.
684 * xm-mips.h: Update KERNEL_U_ADDR for new scheme. Cleanup a bit.
686 * dbxread.c (read_dbx_symtab, process_one_symbol): Handle
687 Sequent N_FN_SEQ like everybody else's N_FN.
689 * main.c: Circumvent SCO cc bug with #if !!defined(USG).
690 * tm-i386v.h: #endif guck.
691 * xconfig/i386*: Remove -Dgetpagesize()=4096 kludge.
692 * xconfig/i386sco: Add HAVE_STRSTR to avoid ANSI bdeath.
693 * xconfig/tahoe: Add REGEX, which seems to be missing.
695 * coredep.c: Add <sys/types.h> for SCOnix.
696 * dbxread.c (read_dbx_symntab): Avoid coredump on malformed file.
697 * printcmd.c (print_formatted): Flush output before disassembly.
699 Tue Oct 15 20:12:32 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
701 * doc/refcard.tex (sec "Working Files"): consistent metavars and
702 other improvements, due to comments by François Pinard
703 (pinard@iro.umontreal.ca)
705 * doc/gdb.texinfo (appendix "Installing GDB"): changes in
706 configure, and improvenets related to Pinard's refcard comments
708 Tue Oct 15 08:45:12 1991 John Gilmore (gnu at cygnus.com)
710 Changes from Fred Fish:
711 * tm-68k.h (FPI_REGNUM): Add.
712 * infrun.c (child_create_inferior): flush stdout and stderr
714 * configure.in: Handle amigados, amix hosts and targets.
715 * inflow.c: Handle TIOCGLTC_BROKEN for Amiga.
718 * values.c (show_convenience): Use printf_filtered.
719 * main.c (define_command): Check result of lookup_command for

725 * i387-tdep.c (double_to_i387): Fix typo for double_to_ieee_extended.
726 * utils.c (_initialize_utils): If !ISATTY, don't paginate.
727 * configure.in, tconfig/decstation, xconfig/decstation: Rename
728 dec3100 to decstation.
730 Mon Oct 14 13:37:50 1991 Roland H. Pesch (pesch at cygnus.com)

733 (nodes Continuing and Stepping; Memory; Targets) clarifications
736 Fri Oct 11 23:27:06 1991 John Gilmore (gnu at cygnus.com)
738 * tm-{irix3,mips,nindy960,pn,symmetry,vx960}.h: Move
739 REGISTER_U_ADDR to corresponding xm- file. Sugg. by Peter Schauer.
741 * symmisc.c (print_partial_symtabs): Add printpsyms debug cmd.
743 * m68k-tdep.c (m68k_push_dummy_frame, m68k_pop_frame): Add
744 generic routines for calling inferior functions.
746 * blockframe.c (inside_main_scope, inside_entry_scope): New.
748 * copying.awk: Filter formfeeds out of copying & warrantee.
749 Make them available as `show copying' and `show warrantee' also.
750 * main.c (print_gnu_advertisement): Advt `show' commands.
752 Thu Oct 10 17:25:47 1991 John Gilmore (gnu at cygnus.com)

755 core-file reading code.
756 * core.c (get_core_registers): Avoid coredump if no .reg section.
758 Wed Oct 9 17:03:34 1991 John Gilmore (gnu at cygnus.com)
760 * mipsread.c, coffread.c: initialise TYPE_VPTR_FIELDNO to -1.
761 This avoids coredumps under `set print object on' in value_headof
762 (called erroneously by value_from_vtable_info) for `p &struct'
763 or `p *struct'. From Peter Schauer.
765 Mon Oct 7 00:06:52 1991 John Gilmore (gnu at cygnus.com)
767 * Makefile.in: Roll version to 4.1.2.
768 * dbxread.c: Use aout64.h, not a.out.gnu.h. Get external symbol entry
769 size from BFD (but, FIXME, we don't yet read external nlists's and
770 convert them to internal nlists's before handling them -- we still
771 assume they have the same size and alignment.) Use SET_NAMESTRING
773 * exec.c (exec_file_command): Move dead coff-encapsulation code
775 * m88k-tdep.c, m88k-xdep.c: Remove encap test and #inc <a.out.h>.
777 Fri Oct 4 22:30:06 1991 John Gilmore (gnu at cygnus.com)
779 * configure.in, tm-i386v.h, xm-i386v.h: Intel 386 Mach host port.
780 * xm-i386mach.h, mach386-xdep.c, xconfig/i386mach: New files.
782 Fri Oct 4 17:04:31 1991 Per Bothner (bothner at cygnus.com)
784 More patches from Peter Schauer <pes@regent.e-technik.tu-muenchen.de>:
785 * mips-xdep.c (store_inferior_registers): Don't try to
786 write the (pseudo) FP.
787 * mipsread.c (parse_partial_symbols): Improved algorithm for
788 setting pst->texthigh.
790 Fri Oct 4 16:47:32 1991 Roland H. Pesch (pesch at cygnus.com)
792 * doc/Makefile: make TEXINPUTS include . everywhere
794 Fri Oct 4 00:35:56 1991 John Gilmore (gnu at cygnus.com)
796 * coffread.c, dbxread.c, symfile.c, symmisc.c, symtab.h: Remove
797 vestiges of typevectors, which were for symsegs and are no longer
798 used. (From a question by Eliot Dresselhaus
799 <dresselh@RFT30.nas.nasa.gov>).
801 Thu Oct 3 09:33:26 1991 John Gilmore (gnu at cygnus.com)
803 * dbxread.c, coffread.c: static-ize functions that were
804 gratuitiously external. (From Fred Fish.)
806 * c-exp.y: sym->class to SYMBOL_CLASS (sym).
808 * dbxread.c (dbx_lookup_type): Keep doubling size of typevector
809 until it is large enough.
811 * dbxread.c (read_type): Handle error case slightly better.
812 Make complaint message not C++-specific.
814 Wed Oct 2 17:21:07 1991 Stu Grossman (grossman at cygnus.com)
816 * infrun.c (wait_for_inferior): Fix step/next so that you only
817 stop at the beginning of a new line. This fixes various problems
818 with for loops, nested if-else's and switch statements.
820 Tue Oct 1 06:33:55 1991 John Gilmore (gnu at cygnus.com)
822 * symtab.c (lookup_symtab_1, lookup_symbol): "fatal" errors
823 between symtabs and psymtabs become ordinary error()s.
825 * dbxread.c (read_dbx_symtab): Relocate end_of_text_addr
826 properly, making "end pc" correct in shared lib psymtabs.
827 (From Guy Harris <guy@auspex.com>.)
829 Mon Sep 30 13:15:31 1991 John Gilmore (gnu at cygnus.com)
831 * dbxread.c: Enable, but soften, const_vol_complaint.
832 (read_dbx_symtab): N_STSYM and N_LCSYM define static vars.
833 Ditto Gould N_NBSTS and N_NBLCS. Also, all types in the psymtab
834 should be file-scope, not global.
835 (read_struct_type): Remove ancient multiple-inheritance warning.
836 (read_range_type): Check base type, complain & patch if undefined.
837 * stack.c (frame_info): Demangle the function name in `info stack'.
840 Sat Sep 28 10:02:33 1991 John Gilmore (gnu at cygnus.com)
842 * eval.c (evaluate_subexp_for_address): Don't use
843 TYPE_POINTER_TYPE directly (it might be zero if this type has
844 never had a pointer created before); use lookup_pointer_type.
845 * symtab.c (lookup_method_type): Arguments were swapped in all
846 callers, so fix it here. I'm amazed this worked at all!
848 Fri Sep 27 18:09:31 1991 John Gilmore (gnu at cygnus.com)
850 * c-exp.y, m2-exp.y: Define more yysymbols that happen to be
851 "bss" rather than "data" symbols, but which still conflict.
854 * coffread.c (coff_symfile_read): Use xmalloc, not malloc.
855 * core.c (core_files_info): Shorten output.
856 * exec.c (exec_files_info): Ditto.
857 (build_section_table): Ignore zero-length sections.
858 * language.c, printcmd.c: Lint.
859 * language.h (get_frame_language): Declare.
860 * saber.suppress: update.
861 * stack.c (find_relative_frame): Remove complex code that was
862 #if 0'd, stick with simple code. Lint.

871 * nindy-tdep.c (nindy_frame_chain_valid): Use lookup_misc_func.
872 (Reported by Mark Peek <mark@imagen.com>.)
874 * solib.c (solib_map_sections): Relocate all sections, even
875 though only the text section's size is tracked. Mark ld_text
876 for eventual elimination as we generalize to N sections.
878 * infrun.c (wait_for_inferior): Don't check if the PC is in a
879 call_dummy if we were stopped by a random signal that is being
880 passed to the program. This produced wierd results when calling
881 functions in the inferior and signals (e.g. SIGALRM) were in use.
883 Tue Sep 24 18:05:30 1991 John Gilmore (gnu at cygnus.com)
885 * infrun.c (IN_SIGTRAMP): Not parenthesized properly.
886 Bugfix from Paul Eggert <eggert@twinsun.com>.
887 * tm-ultra3.h (IN_SIGTRAMP): Ditto.
888 * valprint.c (print_floating): Print 9 digits for IEEE floats.

897 Fri Sep 20 16:10:52 1991 John Gilmore (gnu at cygnus.com)
901 * Makefile.in (VERSION): Set to 4.1.
902 * language.c (set_language_command): Print useful help message,
903 and restore the language string after giving help.
904 * valprint.c (typedef_print): Print typedef in C or M2.
905 * symtab.c (list_symbols): Use it.
906 * main.c (main): Avoid any output before (gdb) prompt when -q.
907 * language.c (set_language_command): Handle errors by restoring
908 the language string to its current state (fix from A. Beers).
909 * doc/gdbint.texinfo: Roll in information from README. Rearrange
910 "how to install" and "how to print the doc" stuff so it drops
912 * configure.in: Rename rtpc CPU to romp to match config.sub.
913 * README, WHATS.NEW, TODO: Update for gdb-4.1.
915 Fri Sep 20 17:39:14 1991 Roland H. Pesch (pesch at cygnus.com)
917 * doc/gdb.texinfo: Updates from ChangeLog. set/show write,
918 autoloading shared libs, copyright etc on GDB startup, clean up $_
919 and $__ index refs, set/show listsize and related updates to list
920 cmd. New host/target configs.
922 Fri Sep 20 15:46:00 1991 Roland H. Pesch (pesch at cygnus.com)
924 * doc/Makefile: generate aux version-no file doc/gdbVN.m4
925 from main Makefile.in version definition
926 doc/gdb.texinfo: use version recorded in doc/gdbVN.m4 for current
928 Makefile.in (setup-to-dist): generate doc/gdbVN.m4
930 * doc/gdb.texinfo: merge new language-switching and lang-specific
933 Fri Sep 20 15:00:57 1991 Per Bothner (bothner at cygnus.com)
935 * mcheck.c: Add __ONEFILE kludge to allow compilation by non-ANSI
936 compilers (which may lack stddef.h).
938 Fri Sep 20 13:29:42 1991 John Gilmore (gnu at cygnus.com)
940 * dbxread.c (read_dbx_symtab, process_one_symbol): N_FN and
941 N_WARNING are the same except for the N_EXT bit, so just use their
942 values alone, rather than OR-ing them with N_EXT.
944 Fri Sep 20 12:27:55 1991 Stu Grossman (grossman at cygnus.com)
946 * mipsread.c (parse_lines): Deal with negative extended line
949 * c-exp.y, m2-exp.y: #define yyerrflag and yynerrs to avoid
950 global symbol conflicts.
952 Fri Sep 20 02:28:15 1991 John Gilmore (gnu at cygnus.com)
954 * .gdbinit: Move 'set complaints' to top, so it runs even in
955 case we aren't debugging GDB.
956 * language.c (_initialize_language): Fix type check and range
957 check documentation strings.
958 * utils.c (!HAVE_VPRINTF): Define vfprintf as a function, so
959 language.c can use it. (Though language.c should really not be
960 handling warnings/errors the way it does, FIXME.)
961 * symtab.c (lookup_primitive_type): const lint.
963 Bugfix from Peter Schauer:
964 * source.c (lines_to_list): Make signed, to avoid comparison
965 going unsigned and complaining that -3 is too high for 21 lines.
966 * stack.c (lines_to_list): Ditto.
968 Thu Sep 19 23:33:41 1991 John Gilmore (gnu at cygnus.com)
970 * Makefile.in (HFILES): Add minimon.h.
971 (VERSION): Roll version number to 4.0.95.
972 (gdb.tar.Z, make-proto-gdb.dir, setup-to-dist, gdb-XXX.tar.Z):
973 New rules for building distributions. Normal distribution
974 is built by doing `make -f Makefile.in gdb.tar.Z' in the directory
975 one level up from here; it calls make-proto-gdb.dir to build a
976 directory `proto-gdb' which is an image of the release. The old
977 `gdb.tar.Z' rule still works too.
978 * config.sub, configure: Roll in latest from ..
980 Thu Sep 19 17:41:24 1991 Roland H. Pesch (pesch at cygnus.com)
982 * doc/gdbint.texinfo: Reorder contents; reorganize new-host,
983 new-target, and new-config chapters; fix minor typos; come closer
984 to usual GNU markup conventions for @file @samp @code @var.
986 Thu Sep 19 17:04:12 1991 Per Bothner (bothner at cygnus.com)
988 Patches from Peter Schauer <pes@regent.e-technik.tu-muenchen.de>:
989 * mipsread.c (parse_partial_symbols): Enter the name of all
990 structs/unions... into the psymtab so we can access them if the
991 symtab is not read in.
992 * mips-tdep.c: Remove some unneeded #includes.
993 * xconfig/dec3100: Add HAVE_STRSTR.
995 Thu Sep 19 15:14:23 1991 John Gilmore (gnu at cygnus.com)

1104 Tue Sep 17 08:37:41 1991 John Gilmore (gnu at cygint.cygnus.com)
1106 Add Andrew Beers' changes for Modula-2 support. His ChangeLog
1107 entries are enclosed herein. Not all of these changes
1108 have been merged into the master GDB sources -- check the
1109 ChangeLog above here for the merge log.
1111 Mon Jun 3 17:05:45 EDT 1991
1113 m2-exp.y Created. Tested outside of GDB for a few days. Proper
1114 operators were added, C specific operators and tokens
1115 removed. yylex() revamped to some extent. Still things
1116 missing from the grammar, such as sets.
1117 Tested for two weeks in GDB v3.5.
1119 Tue Jun 11 17:23:48 EDT 1991
1121 m2-exp.y Added boolean constants TRUE and FALSE to the grammar
1122 so they are built-in. Sort of a hack.
1124 Fri Jun 14 12:53:51 EDT 1991
1126 m2-exp.y Added range checking for numeric constants. Any numeric
1127 constant is assumed to be of builtin type INTEGER unless:
1128 (1) it is octal or hexadecimal, in which case it is a
1129 CARDINAL; (2) it is too big to fit into an INTEGER, in
1130 which case it is a CARDINAL.
1131 eval.c Added simple range checking for +, -, and * on integers.
1132 Doesn't work very well for *, since 6 * 1,000,000,000 =
1133 1,705,032,704, which fails the simple test of result >=
1134 first_operand, no matter in what order the operands are.
1136 Tue Jun 18 14:11:30 EDT 1991
1138 Broke the parser into parts, one containing the C grammar and the other
1139 containing code to be shared by all of the grammars.
1141 The following files no longer exist:
1146 The following files were added:
1148 c-exp.y (The C grammar)
1149 m2-exp.y (The Modula-2 grammar)
1150 parser-code.c (Code that is shared by the above grammar)
1154 Makefile.dist Changed to reflect the above dependencies. NOTE: It is
1155 now necessary to use the Bison compiler compiler, since it
1156 will generate function/variable prefixes other than yy.
1158 Tue Jun 18 16:47:49 EDT 1991
1160 symtab.[ch] Added the external variable working_lang, than holds the
1161 value of the current working language.
1162 Added the ennumerated type language_mode, with the values
1163 language_auto and language_manual, the former meaning that
1164 GDB sets working_lang as needed, and the latter meaning
1165 that the value of working_lang is totally under user
1167 symtab.[ch] Added the Modula-2 pervasive types INTEGER, CARDINAL,
1168 REAL, BOOLEAN and CHAR. Also added the type codes
1169 TYPE_CODE_BOOL and TYPE_CODE_CHAR.
1170 utils.c Added set_language_command and show_language_command to
1171 implement the GDB support commands "set language" and
1173 expression.h A number of identifiers were added to the type exp_opcode
1174 to facilitate Modula-2 builtin functions, integer
1175 division, and array indexing.
1177 Wed Jun 19 13:25:58 EDT 1991
1179 language.h Added the macro STRICT_TYPE, which evaluates to non-zero
1180 if the language specified by working_lang requires the use
1181 of strict typing of expressions. Eventually, even this
1182 will be able to be changed by the user.
1183 Added the macro RANGE_CHECK, which evaluates to non-zero
1184 if the language specified by working_lang requires the
1185 checking of a value against the domain of its type.
1186 Eventually, even this will be able to be changed by the
1188 language.[ch] Predicates involving types (simple_type, ordered_type,
1189 same_type, integral_type, numeric_type, character_type,
1190 boolean_type, float_type) are added. These predicates are
1191 based on the current value of working_lang, and are handy
1194 Wed Jun 19 15:39:34 EDT 1991
1196 eval.c Added the function type_array_rank which computes the rank
1198 valarith.c Added the funtion value_bool, which when given a integer
1199 value.h value (ie. struct value *) as an argument, it returns a
1200 boolean value (ie. struct value *) true if that integer
1201 is non-zero, and a boolean value false otherwise.
1202 valprint.c Added cases for TYPE_CODE_BOOL, so Modula-2 BOOLEAN values
1203 will print out properly.
1205 Wed Jun 19 16:36:34 EDT 1991
1207 valops.c Added the function value_capitalize, which returns it
1208 value.h argument capitalized if its argument is a lowercase
1209 letter, or the argument unchanged if its argument is not a
1211 valarith.c Added the function range_check_p, which returns non-zero
1212 value.h if its value argument is between the integral bounds upper
1214 Added the function range_check_enum_p, which makes sure
1215 that its value argument is a valid member of the domain of
1217 Added the function range_check_range_p, which makes sure
1218 its value argument lies between the upper and lower bounds
1219 of its type argument, which must be a ranged type.
1220 Added the function check_array_index, which range and type
1221 checks an index of an array.
1222 Added the function value_multi_subscript, which computes
1223 array[idx1,idx2...idxN], given a value array and an array
1224 of values representing indicies.
1225 values.c Changed value_from_long to work with TYPE_CODE_CHAR and
1226 unpack_long to work with TYPE_CODE_BOOL and
1229 Wed Jun 19 18:04:08 EDT 1991
1231 symtab.c Stored pervasive types in a structure and make
1232 lookup_pervasive_type() a lookup function that was based
1233 on working_lang. If lookup_pervasive_type() returned
1234 non-zero, then that value was returned (a fix, since
1235 before it simply wouldn't return the pervasive type.)
1236 language.h Added the macro CAST_IS_CONVERSION, which evaluates to
1237 non-zero if the language specified by working_lang means
1238 "conversion" when it says "cast".
1239 valops.c Added the function value_real_cast(), which performs a
1240 value.h *cast*, not a *conversion*, which is what value_cast()
1241 does when it can. In particular,
1242 value_cast(<float_type>,4) = 4.0, while
1243 value_real_cast(<float_type>,4) = some mess.
1244 eval.c Modula-2 builtin functions implemented: ABS, CAP, CHR,
1245 parser-code.c FLOAT, HIGH, MAX, MIN, ODD, ORD, TRUNC, and VAL.
1246 expression.h Added macros MAX_OF_TYPE and MIN_OF_TYPE to work with MAX
1247 and MIN on integral types. *NOTE*: These are currently
1248 hardcoded to work only if there are 8 bits per storage
1250 eval.c Made logical functions call value_bool to return a
1251 properly typed boolean value, based on working_lang.
1253 Thu Jun 20 11:55:27 EDT 1991
1255 valprint.c Types now print out in a Modula-2 fashion. This works for
1256 the cases when the type is printed out step-by-step, that
1257 is, it doesn't work when the name of a structured type
1258 (which includes the keyword "struct", etc.) is simply
1260 FIXME: Perhaps this is bad. Parts of it seem to kludgey,
1261 since type specifications in C and Modula-2 are very
1262 different. The C printing of a type is very recursive,
1263 whereas in Modula-2 it is generally very simple. C has
1264 type prefixes and suffixes, which have no real analogue in
1265 Modula-2. Maybe type_print() should call a language
1266 specific type printer. This is also advantageous if we
1267 compile GDB to exclude some of the languages. We'll just
1268 leave those functions out.
1270 Thu Jun 20 16:57:10 EDT 1991
1272 dbxread.c When reading the complete symbol table in (via
1273 psymtab_to_symtab()), the number and types of function
1274 arguments are added to a function type. define_symbol()
1275 calls add_param_to_type() to accomplish this.
1276 Assumption: when we come across a function definition
1277 (N_FUN symbol with an 'f' or 'F' in the name), its
1278 arguments will appear before another function definition.
1279 When a function is found, a pointer to its type is placed
1280 in the global in_function_type. Changes that
1281 add_param_to_type() makes are to this global.
1282 valprint.c The type of a function now includes (for Modula-2) the
1283 types of its parameters.
1284 eval.c Type checking and a check for the proper number of
1285 arguments is now done for function calls. Not sure of the
1286 impact this has on C++ member function yet.
1288 Thu Jun 20 19:58:48 EDT 1991
1290 valprint.c Rewrote the type printer. Broke it into two language
1291 specific parts, adding the functions type_print_m2() and
1293 An unfortunate consequence is this: if you debugging a C
1294 program in Modula-2 mode (why?), info types does not work
1295 well with regular expressions, since the types are printed
1296 out in Modula-2 terminology, but stored in C terminology.
1297 language.[ch] Added the functions new_type_last(), type_keyword(), and
1298 type_sep() to aid in the printing of typedefs.
1299 symtab.c Made the printing of typedefs as language independent as
1300 possible through calls to new_type_last(), type_keyword(),
1303 Fri Jun 21 11:50:26 EDT 1991
1305 dbxread.c Check all incoming ennumerated types. If it looks like
1306 Modula-2's BOOLEAN type, then change the type_code of the
1307 type to TYPE_CODE_BOOL so we can process it as a boolean
1309 valprint.c Replaced some of the 0x%x with calls to sprintf and
1310 hexformat() in val_print().
1311 language.[ch] Added the function hex_to_string(), which converts its
1312 integral argument to a hexadecimal number (format is
1313 language based) and returns the result as a string.
1315 Mon Jun 24 12:25:07 EDT 1991
1317 valprint.c Some functions call type_print_1() directly, instead of
1318 value.h using type_print(), so they can specify where (column) to
1319 print things. Since type_print() takes care of language
1320 dependence, that needs to be called first. Added a
1321 parameter depth to type_print() (so it is now like
1322 type_print_1). Changed type_print to type_print_at, and
1323 made type_print a macro that passes a depth argument of
1325 symmisc.c Changed all calls to type_print_1 to calls to
1327 Makefile.dist Made it possible to build GDB for a specific set of
1328 depend languages. Do this by passing a definition for the macro
1329 LANGS to make. LANGS should be a string containing a
1330 space-separated list of language names (ie. LANGS="c m2").
1331 The default is to build all languages. Note that grammar
1332 files must follow the naming convention of <lang>-exp.y.
1333 gdb.lang This holds the current value of the LANGS macro. It is
1334 examined every time make is called, and is updated if
1336 eval.c Added #ifdef _LANG_<lang> to these files.
1337 expread.c Still need to add them to dbxread.c and coffread.c.
1345 Mon Jun 24 16:33:11 EDT 1991
1347 language.[ch] Added the functions hexformat_pre() and
1348 hex_to_string_pre(), which take a prefix argument to
1349 include in the format string. Thus, hexformat_pre("08") will
1350 return "0x08x" (if the working language is language_c).
1351 Made hexformat() and hex_to_string() calls to the above
1352 with "" as the prefix argument.
1354 am29k-pinsn.c, arm-pinsn.c, breakpoint.c, convex-tdep.c, exec.c, core.c,
1355 dbxread.c, i386-pinsn.c, i386-stub.c, i386-xdep.c, i960-pinsn.c,
1356 infcmd.c, inflow.c, m68k-pinsn.c, m68k-stub.c, m88k-pinsn.c,
1357 mips-pinsn.c, mips-tdep.c, ns32k-pinsn.c, printcmd.c, pyr-pinsn.c,
1358 pyr-tdep.c, pyr-xdep.c, remote-vx.c, remote.c, solib.c, source.c,
1359 stack.c, sun386-xdep.c, symfile.c, symm-xdep.c, symmisc.c, tahoe-pinsn.c,
1360 valprint.c, vax-pinsn.c
1362 Changed all occurences of 0x%[0-9]*l*x in printf format strings to
1363 calls to hexformat() and hex_to_string(). Format strings without
1364 the leading "0x" were ignored.
1366 depend Updated to take the above into account.
1369 Tue Jun 25 15:27:18 EDT 1991
1371 symtab.h Added the types range_mode_t, range_check_t, type_mode_t,
1372 and type_check_t to keep track of the current state of
1373 range and type checking.
1374 main.c Added the variables range_mode, range_check, type_mode,
1375 and type_check to record the current state of range and
1376 type checking. Added initialization code to main().
1377 language.h Changed the macros STRICT_TYPE and RANGE_CHECK to examine
1378 the above variables.
1381 Tue Jun 25 17:57:08 EDT 1991
1383 dbxread.c process_one_symbol() updates the variable (enum language)
1384 source_lang based on the extension of the filename
1385 contained in the N_SO sybmol that started this symtab.
1386 When end_symtab() is called, the value of source_lang is
1387 put into the language field.
1388 stack.c select_frame() sets working_lang (and possibly type_check
1389 and range_check) to the language field of the symtab
1390 associated with the frame that is selected if working_mode
1391 is language_auto. If working_mode is language_manual, a
1392 warning is printed and working_lang is not set.
1393 language.c Added the function set_type_range(), which sets the value of
1394 type_check and range_check (if their modes call for
1395 automatic setting) based on the current value of
1396 working_lang. A non-zero argument will cause the current
1397 settings to be output.
1400 Wed Jun 26 14:51:40 EDT 1991
1402 eval.c Added range checks on assignment.
1403 m2-exp.y Added the grammar for sets to the language. Currently,
1404 these do not do anything except print an error message.
1406 Wed Jun 26 17:01:04 EDT 1991
1408 m2-exp.y Added the ability for parse_number() to parse negative
1409 numbers. A global flag is set upon encountering a unary
1410 minus. This was done to make, for example, 1 parse as a
1411 CARDINAL, and not as an integer, per Wirth's examples in
1412 Programming in Modula-2 ed.4.
1413 valprint.c Added support for "set radix 2" by then setting
1414 output_format to 't'.
1415 eval.c Implemented range checking on subrange types. Added calls
1416 to range_check_range_p for BINOP_ASSIGN and BINOP_VAL.
1417 Implemented MIN and MAX for ennumerated types. The
1418 minimum value of an ennumerated type is defined by Wirth
1419 as the first identifier, and the maximum as the last.
1420 m2-exp.y Made octal numbers ending with "B" be characters and those
1421 ending with "C" be numbers, per Wirth's book. (p. 34)
1423 Thu Jun 27 14:11:52 EDT 1991
1425 stack.c select_frame() now only sets working_lang, it does not
1426 notify the user. If working_mode is language_manual, then
1427 a warning is issued once.
1428 main.c At the end of each call to execute_command(), working_lang
1429 is checked against the local static (enum language)
1430 current. If they differ and working_mode is
1431 language_auto, the new settings of language, type and
1432 range checking are printed out.
1433 stack.c Modified frame_info() to include the language of the
1434 current frame in the output of "info frame".
1435 language.[ch] Added the function language_str() which returns the name
1436 of the current language.
1438 Fri Jun 28 15:33:14 EDT 1991
1440 m2-exp.y Added the built-in procedures INC, INCL, DEC, and DECL to
1441 the language. INCL and DECL currently cause an error,
1442 since sets are not implemented yet. INC and DEC are
1443 implemented as PREINCREMENT/PREDECREMENT with one
1444 argument, and as ASSIGN_MODIFY with two arguments.
1445 eval.c Added type checking to the above cases.
1446 value.h Added not_lval_constant to the lval_type ennumerated type.
1447 not_lval_constant means that the value is a constant
1448 value; that is 3 or 'a' or TRUE, not as in a constant
1449 identifier. This is used to help coerce numbers such as 3
1450 to either signed or unsigned numbers.
1451 valops.c Added the function value_coerce_constants() which coerces
1452 constant integers as following: if one is a constant and
1453 the other is not, the constant's type is set to the type
1454 of the other argument. If both are constants and one is
1455 signed, the other is converted to a signed constant.
1457 Sat Jun 29 17:26:29 EDT 1991
1459 valarith.c Added a better range checker. It now checks range
1460 (successfully) on integral operations [+-] (signed and
1461 unsigned) for any C sized type. Still does not work well
1462 for multiplication.)
1463 int_in_size() returns an integer that is coerced to fit into
1464 specified number of bytes.
1466 Mon Jul 1 13:04:14 EDT 1991
1468 language.[ch] Added the function binop_result_type(), which returns the
1469 builtin (struct type *) type that would be the result of a
1470 binop on the two values V1 and V2.
1472 Wed Jul 3 19:22:53 EDT 1991
1474 source.c Extended source_info() to include the source language in
1475 the output from "info source".
1477 Fri Jul 5 13:48:52 EDT 1991
1479 utils.c Moved the support functions for the GDB set/show commands
1480 dealing with language into language.c.
1481 language.c Added the function language_info(), which displays info
1482 about the current working language, type and range check
1483 settings. Called via the GDB command "info language".
1484 Added an initialization routine _initialize_language(),
1485 that sets defaults for the language, type and range
1486 variables and sets up the new GDB commands.
1487 main.c Language setup moved to language.c.
1490 Mon Jul 8 10:10:22 EDT 1991
1492 valarith.c Debugged the range checker for arithmetic. Still does not
1493 work for multiplication very well.
1495 Mon Jul 8 12:40:37 EDT 1991
1497 language.[ch] Added the function value_true() which returns non-zero if
1498 its argument represents a boolean true value.
1499 breakpoint.c Changed breakpoint_cond_eval() to call value_true() to
1500 check the truth of an expression.
1502 Thu Jul 11 12:51:34 EDT 1991
1504 language.[ch] Added the predicate structured_type(), which returns
1505 non-zero if the argument is a structured type.
1506 Added the predicate pointer_type(), which returns non-zero
1507 if the argument is a pointer type.
1508 eval.c Added the ability to do addition and substraction on
1509 pointers and integers. This case simply bypasses the
1512 Thu Jul 11 14:41:42 EDT 1991
1515 Added the symbol N_DEFD (0x4a) which is a definition
1516 module dependency that is used by the GNU Modula-2
1517 compiler and the linker. It is not important to GDB,
1518 except that [dbx|coff|mips]read.c should ignore these
1521 Fri Jul 12 16:07:00 EDT 1991
1523 valprint.c Changed the TYPE_LENGTH(type) >= 0 to TYPE_LENGTH(type) >
1524 0 in val_print(). Also added statements to the else part
1525 to coerce type (argument to val_print) to a pointer type
1526 if it is an "array of unspecified length".
1527 valops.c Added the function value_m2_string(), which returns a
1528 (value) value which is a constant string, whose type is
1529 (ARRAY [0..n] OF CHAR). The length field of the type
1530 structure is set to zero, so it will be interpreted as an
1531 "array of unspecified length".
1532 stack.c Moved the language/frame mismatch check to
1533 main.c:execute_command().
1534 main.c The working language is recorded each time
1535 execute_command() is executed. If working lang has
1536 changed during its execution, then the new
1537 language/type/range info is printed out for the user. If
1538 the working language does not match the language of the
1539 frame, a warning is issued.
1541 Sat Jul 13 16:16:39 EDT 1991
1543 eval.c Moved all the type-checking stuff for operators to
1544 language.[ch] language.c. This is so we can keep language-specific
1545 stuff (like for what type operators are defined) in
1547 language.[ch] Added the function binop_type_check(), which checks to see
1548 if its two (value) arguments are type-compatible with its
1549 opcode argument. The opcode should represent an operation
1550 involving an operator. Also added the macro function
1551 unop_type_check, which calls binop_type_check with a
1552 NULL second argument.
1553 expprint.c Added Modula-2 operators to the op_print_tab, so info
1554 expression.h break works correctly. Also added "op_string", which
1555 returns the string corresponding to the (enum exp_opcode)
1556 opcode that is its argument.
1559 Sat Jul 13 18:26:18 EDT 1991
1561 coffread.c Added code to record the type of function arguments with
1562 each paricular function. Code is very similar to that
1564 dbxread.c Moved add_param_to_type() to symtab.c
1565 symtab.[ch] Added function add_param_to_type() from dbxread.c
1567 *** NOTE: The above additions have not been tested.
1569 Mon Jul 15 12:50:47 EDT 1991
1571 langauge.[ch] Added the functions type_error and range_error, which work
1572 like error() except if the type/range mode is set to
1573 *_mode_warn, then they do not do a return_to_top_level(),
1574 but merely print a warning.
1575 Also changed [set|show]_[type|range]_command() to support
1576 the new "warn" feature.
1578 Thu Jul 18 17:50:54 EDT 1991
1580 mipsread.c Added code to record the type of function arguments with
1581 each particular function. Code is very similar to that
1584 *** NOTE: The above additions have not been tested.
1586 Fri Jul 19 11:19:10 EDT 1991
1588 defs.h Added macros MAX_OF_SIZE, MIN_OF_SIZE, UMAX_OF_SIZE, and
1589 UMIN_OF_SIZE, which when given a size of a numeric type,
1590 return the maximum and minimum value it can hold. UMAX...
1591 and UMIN... return the result for unsigned types.
1592 symtab.h Added the macros MAX_OF_TYPE and MIN_OF_TYPE to operate on
1593 struct types. They call above macros.
1594 dbxread.c Renamed the MAX and MIN_OF_TYPE macros to ..._OF_CTYPE to
1595 avoid a name conlict with the above.
1596 c-exp.y Added range checking on numeric constants in
1597 parse_number() for completeness.
1598 valarith.c Made binop_user_defined_p() and unop_user_defined_p()
1599 return 0 if working_lang is not language_c.
1601 Thu Aug 8 14:17:22 EDT 1991
1605 breakpoint.c Documentation strings of some commands changed to
1606 eliminate the references to the C language where
1609 Tue Aug 13 15:48:03 EDT 1991
1611 m2-exp.y Added qualified identifiers to the grammar. The semantics
1612 are slightly different from those of the GDB operator ::
1614 m2-exp.y Added a rule to each grammar of the form: start ::= exp |
1615 type_exp, where type_exp is any valid type expression.
1617 eval.c Added the opcode OP_TYPE, and an error case in eval.c.
1618 printcmd.c Modified ptype_command() so it actually parses the input
1619 (necessary for type expressions with scope qualifiers).
1620 Added the function ptype_eval() which expects an
1621 expression composed of one OP_TYPE element.
1622 *.[ch] Replaced all occurences of parse_c_expression with
1624 *.[ch] Replaced all occurences of parse_c_1 with parse_exp_1
1626 [End of ChangeLog entries from Andrew Beers for Modula-2 support.]
1628 Mon Sep 16 17:19:46 1991 John Gilmore (gnu at cygnus.com)
1630 Small fixes from Peter Schauer:
1632 * infrun.c (child_attach): Lint.
1633 * solib.c (find_solib): Handle shared libs version 2.
1635 Small fixes from David Wood:
1637 * xm-ultra3.h (SYS_SIGLIST_MISSING): Typo.
1641 * remote-vx.c: Move <stdio.h> to top, for FILE. Fix from
1642 John S <basrai%kanga.dnet@c3po.sm-alc.af.mil>.
1644 * utils.c (wrap_here): Avoid wrap action of fputs_filtered if
1645 chars_per_line is at maximum (user typed `set width 0'). Fix
1646 from Andreas Schwab <schwab@ls5.informatik.uni-dortmund.de>.
1648 Tue Sep 17 17:31:04 1991 Stu Grossman (grossman at cygnus.com)
1650 * coredep.c: include ptrace.h where necessary.
1651 * mipsread.c(parse_lines): fix unsigned char problem that was
1652 messing up line numbers on SGI's and possibly other MIPS based
1654 * infrun.c (child_create_inferior): use better test to check
1655 return val from setpgrp().
1656 * tm-irix3.h, xm-irix3.h, tconfig/irix3, xconfig/irix3: add these
1657 for sgi/irix support.
1659 Wed Sep 18 04:33:31 1991 Per Bothner (bothner at cygnus.com)
1661 * mipsread.c (parse_symbol): Put non-static procedures
1662 in the global block.
1664 Fri Sep 13 00:14:52 1991 John Gilmore (gnu at cygnus.com)
1666 Patch together `text_start' and `text_end' for 29K port.
1668 * exec.c (exec_command): If NEED_TEXT_START_END, define the
1669 variables and set them based on the exec file.
1670 * am29k-tdep.c: declare text_start.
1671 * valops.c (call_function_by_hand): declare text_end.
1673 * inferior.h: Eliminate CANNOT_EXECUTE_STACK in favor of
1674 defining CALL_DUMMY_LOCATION as BEFORE_TEXT_END. This is
1675 because machines that do this will also have to know to
1676 set NEED_TEXT_START_END. Besides, it was a redundant way to
1678 * tm-29k.h, tm-convex.h, tm-np1.h: Eliminate
1679 CANNOT_EXECUTE_STACK, define CALL_DUMMY_LOCATION and
1680 NEED_TEXT_START_END.
1682 Thu Sep 12 00:22:24 1991 John Gilmore (gnu at cygint.cygnus.com)
1684 AMD 29000 changes from David Wood <wood@david.ultra.nyu.edu>:
1686 * Makefile.in (CLIBS): Put XM_CLIBS and TM_CLIBS at end.
1687 Pass MUNCH_DEFINE to munch whenever we run it.
1688 * am29k-pinsn.c (print_insn): Handle NOP specially. Avoid %#x
1689 format string; use 0x%x instead.
1690 * am29k-tdep.c: Use DUMMY_SAVE_GREGS and RETURN_REGNUM.
1691 * ultra-xdep.c, xm-ultra.h: New files for Ultracomputer host system.
1692 * xm-rtbsd.h: New host support for RT/PC running BSD Unix.
1693 * inflow.c: Handle `short' process group IDs.
1694 * infptrace.c (fetch_register): Support CANNOT_FETCH_REGISTER,
1695 and check for ptrace errors.
1696 * coffread.c (SDB_REG_TO_REGNUM): Define if not already.
1697 (coff_symfile_init): Initialize text_bfd_scnum.
1698 (read_coff_symtab): Use it to find the text [and absolute?] sections.
1699 * ../config.sub: Add vendor nyu and os "sym[1-9]*".
1700 * configure.in: Add hosts rtpc-*-* and a29k-*-*.
1701 Merge target arm case with other "easy" cases. Add target
1702 cases a29k-*-none (rehack of am29k), a29k-*-kern (remote to
1703 Ultracomputer kernel), and a29k-*-sym1 (ultracomputer OS's user
1705 * minimon.h, remote-adapt.c, remote-mm.c: Add.
1706 * munch: Cope with RT/PC putting fns in data segment.
1707 Restore ability to override `nm' by specifying MUNCH_NM.
1708 * xconfig/rtbsd, xconfig/ultra3: New host systems.
1709 * tconfig/a29k: Rename from tconfig/am29k. Add remote-mm
1710 and remote-adapt. Remove encapsulated coff #define's (the
1711 support should go in BFD, and gdb shouldn't know or care).
1712 * tconfig/a29k-kern: Same, but for remote kernel debugging.
1713 * tconfig/ultra3: For debugging user processes on Ultra3/Sym1.
1714 * tm-29k.h: Update BADMAG (though it should go away).
1715 Allow the register definitions to be overridden in another
1716 tm-file. Fix SR_REGNUM. Add a mess of _REGNUM's. Separate
1717 RETURN_REGNUM from GR96_REGNUM and DUMMY_SAVE_GREGS from
1718 DUMMY_SAVE_GR96, for handling kernel calling conventions
1719 that use GR64+ rather than GR96+.
1720 * tm-ultra3.h: New file, for use on Ultra3 Unix as well as for
1721 remote debugging of Ultra3 kernel. Includes tm-29k.h and
1722 overrides various things.
1724 * remote-mm.c (mm_attach, mm_wait): Handle attach like
1725 child_attach does, making a clean stop in the newly attached
1727 * remote-eb.c: Lint.
1729 * coffread.c: Make coffread independent of any particular
1730 variant of COFF. Avoid #include-ing any particular one except
1731 internalcoff.h. BFD now passes key values for symbol reading
1732 as part of its coff_data structure (LINESZ, SYMESZ, AUXESZ,
1733 and the symbol masks and shifts); use them.
1734 Remove obsolete end_of_text_addr.
1736 * exec.c: Remove unused include files.
1738 Wed Sep 11 19:38:44 1991 John Gilmore (gnu at cygint.cygnus.com)
1740 * Makefile.in (documentation targets): Pass $(M4).
1741 Bugfix from eggert@twinsun.com (Paul Eggert).
1743 * stack.c (down_silently_command): Check for stack existence.
1745 Tue Sep 10 23:08:29 1991 John Gilmore (gnu at cygint.cygnus.com)
1747 * Makefile.in (VERSION): Update to 4.0.3.
1749 Tue Sep 10 09:19:29 1991 John Gilmore (gnu at cygint.cygnus.com)
1751 * core.c (core_file_command): Print frame at coredump with
1752 its level number, by calling print_stack_frame.
1753 * frame.h: Add selected_frame_level, print_stack_frame.
1754 * frame.h, stack.c: Remove print_sel_frame, print_selected_frame.
1755 * convex-tdep.c, convex-xdep.c, infcmd.c, inflow.c, infrun.c:
1756 Change print_sel_frame and print_selected_frame callers to
1759 * dbxread.c (read_ofile_symtab): Avoid empty else clause.
1760 * symfile.c (free_named_symtabs): Ditto.
1761 * main.c (main): wrap_here needs an arg.
1762 * solib.c (find_solib): Avoid memory access if _DYNAMIC is zero.
1763 (solib_add): Avoid noise.
1764 (solib_create_inferior_hook): Lint.
1765 (sharedlibrary_command): Move dont_repeat to here.
1766 * utils.c (error): Call wrap_here to force buffered output.
1768 Small patches from Peter Schauer:
1770 * coffread.c (start_symtab): Free any existing line_vector before
1772 (read_coff_symtab): Ditto for type_vector.
1774 * source.c (lines_to_list): New variable, replacing function.
1775 (all uses): Use as variable.
1776 (_initialize_source): Add 'set listsize' and 'show listsize'.
1777 * utils.c (lines_to_list): Remove function.
1778 * stack.c (print_frame_info): Use as variable.
1779 * defs.h (lines_to_list): Remove declaration.
1781 Mon Sep 9 13:45:57 1991 John Gilmore (gnu at cygint.cygnus.com)
1783 * breakpoint.c (insert_breakpoints): Restore warning about
1784 the program might be running in another process, but only for
1785 systems with this brain death (#ifdef ONE_PROCESS_WRITETEXT).
1786 * xm-hp300bsd.h, xm-mips.h, xm-vax.h: Define it.
1788 * utils.c (error): if error_pre_print is set, print the string
1790 * main.c (main, print_gnu_advertisement, print_gdb_version):
1791 Reformat legalese so it always prints, but acts as an "I'm here"
1792 message while symbols are being read. If any errors occur,
1793 print a few newlines to set off the message and start it at the
1794 left margin. Remove mention of "help" command, and don't yak
1795 about symbol reading.
1796 (catch_errors): Error string is now printed first in case of
1798 * command.c (undef_cmd_error, lookup_cmd): On undefined command,
1799 suggest the "help" command.
1801 * Makefile.in (VERSION): Set to 4.0.2.
1803 Thu Sep 5 23:49:48 1991 John Gilmore (gnu at cygint.cygnus.com)
1805 * .gdbinit: Remove useless "rr" command. Set complaints
1806 to 1 for people debugging gdb.
1808 * breakpoint.c, remote-vx.c: Reword strings printed by
1809 catch_errors callers.
1811 Wed Sep 4 11:07:50 1991 John Gilmore (gnu at cygint.cygnus.com)
1813 * WHATS.NEW: "history write -> history save". Doc "write on/off".
1814 (Fix from kenc@viewlogic.com.)
1816 Fix some infrastructure to be able to cope with host and target
1817 machines with different sized basic types (ints, ptrs, etc).
1818 (Idea from pierre@la.tce.com (Pierre Willard).)
1820 * values.c (value_from_longest): Rename from value_from_long.
1821 Handle pointer types as well as integers, so that targets with
1822 different pointer sizes from the host can be accomodated.
1823 * breakpoint.c, convex-tdep.c, eval.c, expprint.c, printcmd.c,
1824 valarith.c, valops.c, valprint.c, value.h, values.c: Rename
1825 uses of value_from_long to value_from_longest.
1826 * eval.c, findvar.c, printcmd.c, valarith.c, valops.c: Pass
1827 the correct pointer type to value_from_long{est}.
1829 * doc/gdb.texinfo ($_, $__): Describe types of these variables.
1831 * remote-vx.c: Remove obsolete code for calling functions via
1832 vxworks kludge interface (it referenced value_from_long).
1834 * valops.c (value_string): Find malloc with lookup_misc_func, not
1837 Tue Sep 3 18:37:46 1991 John Gilmore (gnu at cygint.cygnus.com)
1839 Make writing to files work properly. (Fixes to BFD are also needed.)
1841 * core.c (core_open): Open file ourselves, read or r/w, depending on
1842 write_files. Use bfd_fdopenr.
1843 * gdbcore.h (write_files): New variable.
1844 * exec.c (write_files): Define variable, add set&show for it.
1845 (exec_file_command): Use write_files to open for read or r/write.
1847 Make shared library reading happen automatically. These changes
1848 are mostly from Peter Schauer <pes@regent.e-technik.tu-muenchen.de>.
1850 * inferior.h (stop_soon_quietly): Add to exported variables.
1851 * infrun.c (child_create_inferior): call solib hook, if defined.
1852 (child_attach): call solib hook, if defined.
1853 * solib.c: Include inferior.h. Add from_tty to so_list as kludge.
1854 (find_solib): Use lookup_misc_func rather than hand-rolled.
1855 (symbol_add_stub): New stub for catch_errors.
1856 (solib_add): Avoid output if !from_tty. Catch errors rather
1857 than just calling symbol_file_add and bombing.
1858 (solib_create_inferior_hook): Interface with the target process
1859 to let it read and alloc shared libs, then figure out what it did.
1861 * core.c (validate_files): Fix typo, soften warning.
1862 (Fix from Hiroto Kagotani <kagotani@cs.titech.ac.jp>.)
1864 * utils.c (fputs_demangled): Avoid duplicate printing if
1865 demangling is off. (Fix from J.T. Conklin <jtc@cayenne.com>.)
1867 * infrun.c (proceed): Cast -1 to (CORE_ADDR) before comparing.
1868 (Fix from pierre@la.tce.com (Pierre Willard).)
1870 * main.c (catch_errors): Change argument to a char * from an int,
1871 since a char * can point to a struct full of glop, but an int
1872 is not guaranteed to be able to hold a pointer.
1873 * breakpoint.c (breakpoint_cond_eval, bpstat_stop_status,
1874 breakpoint_re_set_one, breakpoint_re_set): Adapt.
1875 * core.c (core_open, solib_add_stub): Adapt.
1876 * remote-vx.c (symbol_stub, add_symbol_stub, callers): Adapt.
1878 Wed Aug 28 18:18:05 1991 John Gilmore (gnu at cygint.cygnus.com)
1880 * Makefile.in: Update VERSION to 4.0.1. Evade GNU Make bug
1881 by adding .NOEXPORT target.
1883 Fri Aug 23 17:14:25 1991 John Gilmore (gnu at cygint.cygnus.com)
1887 * Makefile.in (VERSION): Roll to 4.0.
1888 (gdb.tar.Z): Make refcard.ps as well, for shipment.
1890 Fri Aug 23 14:07:09 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1892 * doc/gdb.texinfo: minor rewordings, crossref to ptype from print,
1895 * doc/Makefile, Makefile.in: generate "gdb-all.texi" rather than
1898 * doc/rdl-apps.texi: renamed from rdl-apps.texinfo
1900 * Makefile.in, doc/Makefile, doc/.Sanitize, doc/gdb.texinfo:
1901 reflect above name change
1903 * WHATS.NEW: correct pointer to refcard.
1905 * doc/gdb.texinfo: update New Features, Installing
1907 * doc/gdbint.texinfo: add short description of configure +template
1909 Fri Aug 23 11:46:08 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1911 * doc/gdb.texinfo: update, fix bugs in "Installing" appendix
1913 Fri Aug 23 01:02:00 1991 John Gilmore (gnu at cygint.cygnus.com)
1915 * Makefile.in: Add config.sub, make doc/rdl-apps.texinfo for
1916 tar file, add dependencies for referenced doc files.
1918 Thu Aug 22 22:17:06 1991 Stu Grossman (grossman at cygint.cygnus.com)
1920 * coffread.c, symfile.c, stack.c: saberized.
1922 Thu Aug 22 16:20:27 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1924 * doc/refcard.tex: permuted Essential Commands sec
1926 * doc/gdb.texinfo: new C++ chapter; revised installation appendix;
1928 set/show symbol-reloading
1929 default set complaints 0
1931 RET-repeat disabled after prompted long displays
1932 processID (attach) interpretation of 2nd GDB cmdline arg
1934 Thu Aug 22 14:05:47 1991 Stu Grossman (grossman at cygint.cygnus.com)
1936 * expread.y, coffread.c, dbxread.c, target.c, mem-break.c,
1937 cplus-dem.c, values.c, valprint.c, symfile.c, remote.c,
1938 breakpoint.c, main.c: lint.
1940 Thu Aug 22 02:02:26 1991 John Gilmore (gnu at cygint.cygnus.com)
1942 Install new configuration scheme for GDB and friends.
1944 * config.sub: Translate ordinary names to three-part names.
1945 * configure: Use three-part names internally.
1946 * configure.in: Translate three-part names to filenames.
1948 * README, WHATS.NEW: Update for gdb-4.0.
1949 * Makefile.in: Roll VERSION to 3.99.
1951 Wed Aug 21 18:21:09 1991 John Gilmore (gnu at cygint.cygnus.com)
1953 * infptrace.c (KERNEL_U_ADDR_BSD): Include a.out.gnu.h.
1954 * i960-tdep.c, m68k-tdep.c, sparc-tdep.c, tm-i960.h,
1955 tm-m68k.h, remote-nindy.c: Change ext_format_XXX structs
1956 to single structures rather than arrays; when passing
1957 their address, use &. This avoids trouble with bdead compilers.
1958 * mcheck.c: Don't include <stdlib.h>; just declare "void abort();"
1959 instead. This avoids portability headaches.
1960 * mips-tdep.c (mips_do_registers_info): Only print FP regs if
1962 * source.c (open_source_file): Avoid ANSI const bdeath by
1963 skipping declaration and then casting result value.
1964 * tm-hp300bsd.h: Clarify comment.
1965 * utils.c (strstr): Result is const char *; ANSI bdeath.
1966 * xm-hp300bsd.h: Define HOST_BYTE_ORDER. Redefine INT_MIN,
1967 since system include file defines it differently from "defs.h",
1968 though the two are equivalent for our purposes.
1969 * tconfig/hp300bsd: Add m68k-tdep.o.
1971 Tue Aug 20 16:01:11 1991 John Gilmore (gnu at cygint.cygnus.com)
1973 * tconfig/sun*4: Remove warnings about system assembler.
1975 Mon Aug 19 13:44:46 1991 John Gilmore (gnu at cygint.cygnus.com)
1977 * mcheck.c: Avoid warning about undeclared abort fn.
1978 * tm-sparc.h (PC_ADJUST): Avoid calling error() from this;
1979 it causes recursive calls to error() when used in cleanups.
1980 To do so requires that we make it a function, so we do.
1981 * sparc-tdep.c (sparc_pc_adjust): New implem of PC_ADJUST.
1982 * utils.c (do_cleanups): Remove the current cleanup from the
1983 chain *before* calling it, in case error() is called from it.
1984 The result won't be pretty, but won't be an infinite loop either.
1986 Mon Aug 19 00:41:04 1991 Michael Tiemann (tiemann at cygint.cygnus.com)
1988 * dbxread.c (read_struct_type): Grok anon structs for C++.
1989 (vb_name, vptr_name): Null terminate these strings.
1991 Fri Aug 16 08:31:03 1991 John Gilmore (gnu at cygint.cygnus.com)
1993 Minor bug fixes from BSD Net2 gdb:
1995 * blockframe.c (get_prev_frame_info): If FRAME_CHAIN_COMBINE
1996 returns 0, there is no previous frame.
1997 * breakpoint.c (commands_command): If !from_tty, don't call
1998 input_from_terminal_p().
1999 * dbxread.c (record_misc_function): Speed up slightly.
2000 (compare_psymbols): Ditto.
2001 * infcmd.c (do_registers_info): Take a second argument to
2002 determine whether to print float registers. "info registers"
2003 does not do so anymore. "info all-registers" does, now.
2004 * mips-tdep.c, pyr-tdep.c (xxx_do_registers_info): Take second
2006 * tm-mips.h, tm-pyr.h (DO_REGISTERS_INFO): Pass second arg.
2007 * inflow.c (initialize_inflow): Set tflags_ours correctly.
2011 * breakpoint.c (bpstat_do_actions): Use a cleanup to restore
2012 executing_breakpoint_commands if we are interrupted by error.
2013 * coffread.c (init_lineno): Avoid problem with zero-sized linetab
2014 versus malloc/free. From: john@labtam.labtam.oz.au (John Carey).
2015 * core.c (solib_add_stub, core_open): Call SOLIB_ADD inside a
2016 catch_errors() so we can setup the frame regardless of whether
2017 the shared libs work.
2018 * ieee-float.c (double_to_ieee_extended): Get exponent from
2019 right place in little-endian systems. From John Carey.
2021 Thu Aug 15 18:43:57 1991 John Gilmore (gnu at cygint.cygnus.com)
2023 * main.c: Remove unused terminating_signals and catch_termination().
2024 (long_options): Terminate with a zero element.
2025 [Bugfix from Atsuo Kawaguchi <atsuo@hark86.harl.hitachi.co.jp>.]
2026 (gdb_readline): Make call-compatible with readline.
2027 (init_signals): Improve comments re vfork vs. signal.
2029 * utils.c (prompt_for_continue): Use new gdb_readline().
2030 If we prompt for continuation, we don't let CR repeat the previous
2031 command, once we get back to a prompt. It's too easy to keep
2032 hitting CR, expecting "--more--" prompts, and have some long
2033 command start repeating on you.
2035 Tue Aug 13 16:17:56 1991 John Gilmore (gnu at cygint.cygnus.com)
2037 * blockframe.c (frameless_look_for_prologue): Speed up by
2038 calling SKIP_PROLOGUE_FRAMELESS_P if it's defined.
2039 * tm-sparc.h (SKIP_PROLOGUE, SKIP_PROLOGUE_FRAMELESS_P):
2040 Define two variants, one faster.
2041 * sparc-tdep.c (sparc_frame_chain): Use target_read_memory
2042 and return zero, rather than giving an error.
2043 (setup_arbitrary_frame): Initialize the PC in the new frame.
2044 (skip_prologue): Add a second arg saying whether we're just
2045 checking for a frameless function or not.
2047 * core.c (core_open, core_close, core_xfer_memory): Move
2048 section table pointers and bfd* into the target_ops.
2049 (core_open): Allow errors in shared lib reading, etc.
2050 (core_files_info): Describe shared library sections.
2052 * exec.c (exec_open, exec_close, exec_xfer_memory, xfer_memory,
2053 exec_files_info, set_section_command): Move section table
2054 pointers and bfd* into the target_ops.
2055 (add_to_section_table): Add BFD to section table.
2057 * target.c (target_xfer_memory, target_info): Pass target to
2058 xfer_memory and target_info functions.
2061 * gdbcore.h: Move struct section_table.
2062 * target.h: New home of struct section_table.
2064 * solib.c (solib_add): New argument is the target_ops whose
2065 section list is to be added to, if any. Reallocate the
2066 sections in that target to add any that come from shared libs.
2067 (throughout) so_sections renamed to sections.
2068 (solib_xfer_memory): Deleted.
2069 * tm-sunos.h (SOLIB_ADD): Add target argument.
2070 (SOLIB_XFER_MEMORY): Delete.
2072 * core.c, exec.c, inftarg.c, remote-eb.c, remote-nindy.c,
2073 remote-vx.c, remote.c, target.c, target.h: Remove add_syms vector
2074 from target_ops. It's the same on all targets. Add two section
2075 pointers to target_ops.
2077 * stack.c (find_relative_frame): Dump ancient algorithm for
2078 "down", just use handy "next" pointers.
2079 (frame_command): Don't error if there is no stack; let user
2082 * inflow.c (new_tty_prefork, new_tty): New prefork routine
2083 modifies static state in the parent process; new_tty itself
2084 runs in the child and modifies the child's file descriptors
2085 to match the saved static state.
2086 * infrun.c (child_create_inferior): Call new_tty_prefork,
2089 * infptrace.c (child_xfer_memory): Add ignored target arg.
2090 * remote-eb.c (eb_xfer_inferior_memory): ''
2091 * remote-nindy.c (nindy_xfer_inferior_memory): ''
2092 * remote-vx.c (vx_xfer_memory): ''
2093 * remote.c (remote_xfer_memory): ''. Rename from
2094 remote_xfer_inferior_memory.
2096 * main.c (main): Only try to attach "corefile" argument if
2097 it starts with a digit.
2099 * symfile.c (symbol_reloading): New "set/show" variable.
2100 (symbol_file_add): Shorten message about symbol reading.
2101 (add_symbol_file_command): Merge with add_syms_addr_command,
2102 since this should work on all targets now.
2103 (stop_whining): Default to zero, to shut up complaints
2104 about bad symbol tables on many systems.
2105 (free_named_symtabs): Just exit unless symbol_reloading.
2107 * xm-sun3os4.h, xm-sun4os4.h: Define BROKEN_LARGE_ALLOCA,
2108 and add comment explaining shared library screw.
2110 * source.c: #if defined => #ifdef.
2112 Thu Aug 8 12:23:19 1991 John Gilmore (gnu at cygint.cygnus.com)
2114 * doc/gdbint.texinfo: Improve doc on porting to new OS's.
2116 Tue Aug 6 17:16:15 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
2118 * doc/rdl-apps.texinfo: provide default readline-appendix finder
2119 (doc/Makefile knows how to make one for local config)
2121 * Makefile.in: use doc/Makefile for doc targets
2123 * doc/Makefile: GDB documentation now has its own Makefile
2124 doc/refcard.tex: renamed from "gdbrc.tex"
2125 doc/.Sanitize: add Makefile; recognize renamed refcard.tex
2126 doc/gdbint.texinfo: add markup in "Cleanups" chapter
2129 Fri Aug 2 00:13:06 1991 John Gilmore (gnu at cygint.cygnus.com)
2131 * values.c (baseclass_addr): When reading target memory, use the
2132 length of the basetype, not the upper type. We've only malloc'd
2133 enough space for the basetype, leading to errors in free().
2135 * expprint.c (print_subexp): Print UNOP_MEMVAL of an OP_LONG that
2136 ends up as a function specially, since we know the actual type of
2137 the pointed-to address. This (somewhat) fixes display of
2138 expressions that include misc_function_vector names. Try `cond 1
2139 !strcmp("a","b")' then `i b'.
2141 * infrun.c: Move DO_DEFERRED_STORES from proceed() to resume().
2142 The child can be proceeded from inside wait_for_inferior in
2143 evaluating breakpoint conditions, and DO_DEFERRED_STORES was
2144 getting skipped in that case.
2146 * expprint.c (print_subexp): Use filtered output, since the
2147 subroutines we call use it, otherwise the output is horribly
2148 mangled, since output of wrappable stuff comes out late.
2150 * Makefile.in: Bump VERSION to 3.98.1
2152 * infrun.c (child_create_process): Use execlp to find the
2153 shell to exec our target program. This requires some fiddling
2154 with `environ' since there is no execlpe().
2156 Thu Aug 1 15:35:17 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
2158 * Makefile.in, doc/gdbrc.tex, doc/rc-* (new files):
2159 Minor rearrangement of refcard permits two new make targets--
2160 gdbrc.dvi DVI output for refcard, using CM fonts
2161 gdbrc.ps PostScript refcard, using PS fonts
2163 Wed Jul 31 16:46:21 1991 John Gilmore (gnu at cygint.cygnus.com)
2167 * TODO, Projects, WHATS.NEW, README: Update for gdb-3.98.
2168 * Makefile.in (gdb-all.texinfo): Avoid touching file if M4 dies.
2170 Wed Jul 31 16:35:58 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
2172 * doc/gdb.texinfo: last changes for release.
2173 Minor typo and formatting fixes; incorporated most fixes remaining from
2174 filed mail commenting on earlier drafts.
2176 Added warnings: pipes don't work in run command;
2177 conditions are converse of assertions;
2178 step over fn without debug info goes to next fn;
2179 vars may have "wrong" values near fn entrance, exit
2181 Added example from Kingston on printing repeated nonadjacent values
2183 Added explicit mention that in Emacs gdb mode C-c and C-z are like
2184 shell mode for signals
2186 Renamed "Stepping and Continuing" to "Continuing and Stepping" so it
2187 doesn't sound so much like its parent "Stopping and Continuing"; also
2188 moved entries on continue to top of section, so they don't get lost.
2190 Improved installation directions in appendix, added manual formatting
2193 Tue Jul 30 17:26:39 1991 John Gilmore (gnu at cygint.cygnus.com)
2195 * configure.in: Remove xm.h and tm.h even if we aren't linking
2196 new ones, so "./configure sun4; ./configure none" does the right
2197 thing. Assume that alldeps.mak and depend are already built in
2198 srcdir, and avoid running "make" (particularly "make depend",
2199 which involves "gcc") from inside configure. Build Makefile
2200 directly rather than building Makefile.conf first.
2201 * configure: Regenerate with above changes.
2202 * Makefile.in: Use $(BISON) to find bison. Roll VERSION
2203 to 3.98. Revise gdb.tar.Z procedure to produce a file
2204 called gdb-$(VERSION).tar.Z but which unpacks into a
2205 directory called "gdb". Move non-source files out of
2206 $(SFILES_SUBDIR). Pretty up alldeps.mak with comments.
2207 (depend): Don't try to do "gcc expread.y".
2208 (expread.o): Update dependencies by hand.
2210 Mon Jul 29 15:21:09 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
2213 Fixed a variety of small typos that prevented info from formatting
2214 cleanly; altered too-long heading for GPL Appendix, as discussed
2215 w/RMS; Changed date on cover to July 91.
2217 Fri Jul 26 13:20:02 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
2220 (1) Applied some fixes due to comments from Larry Breed (easier ones
2221 through chapsec 5.2)
2222 (2) Eliminated use of @footnote---had my doubts about it anyways, and
2223 it's broken in latest texinfo
2224 (3) Introduced *some* use of [] for optional arguments, where
2225 explanation is not simpler by listing cmd w arg and cmd w/out arg
2226 separately. Still not using @deffn.
2227 (4) Dropped in GPL-2. NOTE: one of GPL-2 or texinfo is broken; a
2228 couple of headings are too long. Need patches to texinfo or revision
2231 * Partial update to README (which still needs work for this
2232 release!): (1) use of configure corrected for new script,
2233 (2) "make gdb.dvi" and "make gdb.info" mentioned.
2235 Wed Jul 24 06:44:02 1991 John Gilmore (gnu at cygint.cygnus.com)
2237 * symtab.c (lookup_symbol): Don't complain right off about
2238 no debug symbols; use the misc function vector first.
2239 (list_symbols): Use misc function vector to find symbols
2240 that don't have debug info, and print them.
2241 (find_pc_symtab): Temporarily avoid fatal() when psymtab
2242 PC range doesn't match symtab PC range, as it does on the
2243 MIPS because our symtab reading isn't perfect.
2245 * dbxread.c (dbx_symfile_read): Make warning about
2246 "no debug symbols" slightly nicer.
2248 * source.c (select_source_symtab): If "main" symbol exists,
2249 but decode_line_spec can't find line info, don't just return
2250 a zero; try other source symtabs or give an error.
2252 * mipsread.c (parse_partial_symbols): Sort the psymtabs by
2253 their low addresses first, then rip through fixing high addrs.
2255 * ns32k-opcode.h (sfsr): Bugfix from Rune Nerg}rd,
2256 <runene@ifi.uio.no>.
2257 (NS32K_SVC_IMMED_OPERANDS): Reverse the #ifndef.
2259 Tue Jul 23 18:52:43 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
2261 * Minor, mostly mechanical, cleanup of doc subdir for clean
2262 makeinfo'ing and TeXing; also ensured gdb-all.texinfo (post-m4)
2263 and gdb.info (post- texinfo2 makeinfo) generated for distribution.
2265 Sun Jul 21 03:54:52 1991 John Gilmore (gnu at cygint.cygnus.com)
2267 Mostly MIPS and general symbol-reading fixups.
2269 * doc/gdbint.texinfo: Add documentation on symbol-reading
2272 * mipsread.c: Remove kludges around #include "ecoff.h".
2273 Remove redefinitions of a_magic, etc, no longer used.
2274 (parse_symbol, ): Convert "Internal:" printfs to complain()ts.
2275 Fix global overview comments to match symfile.c protocol.
2276 (mipscoff_new_init): Eliminate cur_hdr if we have one.
2277 (mipscoff_symfile_read): Eliminate unused code. Avoid
2278 sorting all the symtabs, when all we have read here is psymtabs.
2279 The symtabs are sorted as they are created anyway. Tell
2280 condense_misc_bunches whether we're mainline.
2281 (psymtab_to_symtab_1): Pass filename when recursing, to make
2282 stack trace more informative.
2283 (parse_partial_symbols): Assume cur_hdr as argument.
2284 (read_mips_symtab): Don't clobber cur_hdr, so it can be freed.
2285 Pass cur_hdr implicitly to parse_partial_symbols. Avoid checking
2286 the TYPE_NAME of char *, since that's done in symfile.c.
2287 (free_numargs, parse_symbol, add_symbol, add_block,
2288 shrink_linetable): Declare these fns void.
2289 (upgrade_type): Convert tree of if's to switch. Clean up
2290 bogus "off == 0" handling with a complaint. Avoid setting
2291 field bitpos and bitsize of array with lower and upper bounds.
2292 Check specified bitsize of elements against their actual type's
2293 bitsize, and complain if different. Complain about unknown
2295 (parse_fdr): Don't assume sizeof(char *) == sizeof (struct *).
2296 (psymtab_to_symtab_1): Print names of subsidiary files that
2297 are being read in. FIXME, we read far too many files. This code
2298 is not the problem, the problem is in parse_fdr where the psymtabs
2300 (cross_ref): Result should indicate that we used one aux entry
2301 normally, or two if we encountered a "next" entry. This used
2302 to leave the caller pointing at the wrong aux entry.
2303 (add_symbol): If overflowed cur_block, reallocate it larger,
2304 chase all pointers to it, and complain(), rather than clobber memory.
2305 (shrink_block): Use xrealloc rather than xmalloc-and-copy.
2306 (new_field): Only allocate one field initially, not two.
2307 Pull ++ out of macro argument. Simplify.
2308 (_initialize_mipsread): Avoid initialization of importd
2309 global_psymbols and static_psymbols.
2311 * symfile.c (psymtab_to_symtab): Depend on XXX_psymtab_to_symtab
2312 to properly set pst->symtab; avoid searching for it.
2313 (symfile_fns): Improve comments, add a FIXME.
2314 * dbxread.c: Update comments to reflect symfile protocol.
2315 (read_ofile_symtab, end_symtab): Return the symtab.
2316 (psymtab_to_symtab_1): Set pst->symtab.
2318 * coffread.c (coff_symfile_read): tell condense_misc_bunches
2319 whether we're mainline.
2321 * symfile.h (sym_fns): Remove unused sym_discard member.
2322 * coffread.c, mipsread.c, dbxread.c: Remove XXX_symfile_discard.
2324 * mtrace.c (mtrace): Take effect if mallwatch is set, even if
2325 the environment variable is not.
2326 * infcmd.c (finish_command): Use filtered printfs.
2327 * cplus-dem.c: Add struct tags to a few unnamed structs.
2328 * valops.c (value_coerce_array): Improve comments.
2329 * valprint.c (type_print_varspec_suffix): Print array size only
2330 if greater than zero.
2331 * m88k-tdep.c: Shift some lines left by one space, that had
2332 apparently been trashed at some point.
2333 * TODO: More things to do, a few got done.
2335 Thu Jul 18 22:46:05 1991 John Gilmore (gnu at cygint.cygnus.com)
2337 * symtab.h (LOC_EXTERNAL): Eliminate in favor of LOC_STATIC.
2338 (ldsymoff, ldsymlen, globals_offset, statics_offset): Improve
2340 * dbxread.c (read_dbx_symtab): LOC_EXTERNAL -> LOC_STATIC.
2341 * expread.y, findvar.c, symmisc.c: Ditto.
2342 * printcmd.c (address_info): Update printed forms of LOC_
2343 symbols. Elim LOC_EXTERNAL.
2344 (print_frame_args): Keep track of param stack offsets before
2345 re-looking up to find the local register param is kept in.
2347 * mipsread.c: Use <symconst.h> and <sym.h> rather than <syms.h>.
2348 Further integration of mipsread into gdb. Eliminate unused
2349 routines, duplicate declarations. Handle static symbols in
2350 psymtabs as well as external symbols. When reading symtabs,
2351 insert symbols into the correct block (global, static, or a local
2353 (read_mips_symtab, parse_partial_symbols): Don't pass useless
2355 (mipscoff_symfile_read): Don't call select_source_symtab.
2356 (parse_symbol): Use SYMBOL_VALUE_ADDRESS where appropriate,
2357 rather than SYMBOL_VALUE.
2358 (parse_external): Comment clobbering of top_stack.
2359 (parse_partial_symbols): Update comments. Allocate and parse
2360 static symbols as well as external symbols. FIXME, enum values
2361 are not handled in this pass, but should be. Inline new_psymbol.
2362 Use SYMBOL_VALUE_ADDRESS.
2363 (psymtab_to_symtab_1): Read symbols into global static block
2364 by default (until enter some function's local block context).
2365 (sort_blocks): Clean up STATIC_BLOCK as well as GLOBAL_BLOCK.
2366 (destroy_all_symtabs, new_psymbol): Eliminate, unused.
2368 * source.c (select_source_symtab): Select a source symtab
2369 from either the symtabs or, failing that, the psymtabs.
2370 (list_command): Update error message.
2371 (forward_search_command, reverse_search_command): Use getc, not
2372 fgetc, for speed. FIXME, add comment about buffers that die if
2373 overrun by long line.
2375 * values.c (unpack_field_as_long, modify_field): Avoid shifting
2376 by an entire word, which is not portable, if we have a 32-bit
2377 field. (Code in dbxread.c already turns such bitfields, if
2378 aligned, into ordinary ints, but fixing this will help for other
2379 symbol formats and for future changes.)
2380 * core.c (core_open): Handle ANSI const brain death.
2381 * utils.c (vprintf): Fix varargs typo.
2383 Sun Jul 14 00:42:53 1991 John Gilmore (gnu at cygint.cygnus.com)
2385 * findvar.c (find_var_value): Handle &function better.
2386 * TODO: Document work needed on &fn and &array.
2387 * printcmd.c (print_address_symbolic): New arg is the prefix
2388 to print if a name is printed.
2389 (print_address_demangle): Honor "set print address" now.
2390 Use new arg above to improve spacing of output.
2391 * valprint.c (val_print): When printing function pointers,
2392 print symbolic form too.
2393 * breakpoint.c (breakpoint_1): Use new print_address_symbolic.
2395 Mon Jul 8 19:02:46 1991 John Gilmore (gnu at cygint.cygnus.com)
2397 * core.c (memory_error): Reword error msg to mislead less.
2399 * mips-pinsn.c (print_insn_arg 'd'): Print $ with reg name.
2401 * mipsread.c (read_mips_symtab, read_the_mips_symtab,
2402 parse_partial_symbols): Use newer BFD internals (external_filehdr
2403 and external_aouthdr), byte-swap the fields that we care about
2404 before using them, and make the file header data local to
2405 read_the_mips_symtab rather than global.
2407 Sat Jul 6 01:34:15 1991 John Gilmore (gnu at cygint.cygnus.com)
2409 * ns32k-opcode.h (movmw, movmd): Fix opcodes. Bug fix
2410 from Rune Nerg}rd <runene@ifi.uio.no> on 5 Jul 1991.
2412 * main.c (command_line_input): Flush stdout and stderr
2413 before every call to readline. This reportedly fixes a bug
2414 that comes up in Sys V running emacs-gdb and/or xxgdb,
2415 when stdin/out are pipes or sockets.
2417 Thu Jul 4 14:47:06 1991 John Gilmore (gnu at cygint.cygnus.com)
2419 * configure.in, Makefile.in: Avoid rebuilding "depend" as much.
2420 Avoid declaring Makefile dependencies, because GNU Make stupidly
2421 tries to update it if we do.
2423 * coffread.c: Revise for minor changes to bfd internal coff
2426 * configure: If -template= is given a relative path, make it
2427 absolute before recurring in subdirectories.
2429 * configure, configure.in, Makefile.in: Install "configure" script
2430 as replacement for config.gdb.
2431 * config.gdb, Makefile.dist, Makefile.sdir: Remove
2432 * README: Update for configure, mostly. FIXME.
2434 * Add dec3100 as equivalent to littlemips. Indicate in all host &
2435 target config files that they are for the host. When the lines
2436 get copied into the Makefile, this makes it more obvious what's
2439 Mon Jun 24 23:49:07 1991 John Gilmore (gnu at cygint.cygnus.com)
2441 * sparc-opcode.h (trap opcodes): Avoid leading spaces or
2442 tabs, which end up in the disassembler output inadvertently.
2444 Wed May 29 23:01:03 1991 John Gilmore (gnu at cygint.cygnus.com)
2446 Make it compile cleanly in an ANSI GCC2 environment.
2448 * blockframe.c: <stdio.h>
2449 * cplus-dem.c: free takes a void *, ifdef __STDC__
2450 * dbxread.c (read_huge_number): avoid gcc2 bug hoisting calc of
2452 * defs.h (alloca): Avoid doing anything if alloca already def'd.
2453 * stddef.h, stdlib.h: Remove these files.
2454 * symtab.c: Avoid declaring qsort, close.
2455 * symfile.c: Avoid declaring close.
2456 * utils.c (vprintf): Declare "ap" arg as proper va_alist.
2457 * sparc-tdep.c: Avoid including lots of Sun-host-specific files.
2459 Assorted other changes.
2460 * dbxread.c: include "libaout.h", not "liba.out.h".
2461 * printcmd.c (print_frame_args): Set recurse properly for
2462 indentation of struct and array parameters.
2463 * valops.c (value_cast): Allow cast to void.
2464 * infrun.c (resume): If NO_SINGLE_STEP, call machine dependent
2465 single_step() in a target-independent fashion.
2466 * sparc-tdep.c (single_step): Don't call ptrace ourselves, just
2467 set up to be ready to continue. This makes us target independent.
2468 * infptrace.c (child_resume): Remove call to single_step; now
2469 can single step a SPARC target of any kind.
2471 Wed May 22 18:18:24 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
2473 * Makefile.dist, doc/gdb.texinfo, doc/*-m4.texinfo: split up GDB
2474 docn into separate sections---basically chapters, plus two loose
2475 pieces that can be configured to go in different places. This
2476 allows GNU m4 to preprocess the manual without coredumping.
2478 * Makefile.dist: tell TeX where to find texinfo.
2480 Mon May 20 12:15:04 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
2482 * Makefile.dist, doc/gdb.texinfo: respectively create, and use,
2483 the new target "rdl-apps.texinfo" which captures the Makefile
2484 variable that records where to find the Readline libraries.
2486 Sun May 19 05:36:59 1991 John Gilmore (gnu at cygint.cygnus.com)
2488 * tahoe-pinsn.c: #include "tahoe-opcode.h", not "opcode.h".

2490 * defs.h (const, volatile): Only define if not already defined.
2491 * Makefile.dist (gdb.tar.Z): Create doc subdir w/out CVS/RCS crud.
2493 * README: Update for release 3.95.
2494 * config.gdb: Don't create readline dir in subdir builds.
2495 * main.c: Include with "..." form for non-system include files,
2496 so "gcc -MM" for "make depend" works.
2497 Include readline files with "...h" rather than <readline/...h>.
2498 * mipsread.c: Include "ecoff.h" rather than "intel-coff.h".
2500 * coffread.c: Undo minor damage done by Rich Pixley. Use
2501 different internal and external representations of COFF
2502 data structures. Use new BFD routines for swapping them in and
2504 * symfile.c (free_named_symtabs): Avoid freeing file names that
2505 are null or empty. Old i960 tools seem to produce files that
2506 claim to have empty names, causing each successive file read
2507 to blow away the previous one.
2508 * sparc-xdep.c (deferred_stores): Repair minor damage by Rich.
2509 Move deferred_stores to top of file, but don't separate its
2510 #define's from its variable. Add commentary.
2511 * Makefile.dist: Fix Rich damage; undo "configure" changes in
2512 favor of keeping the (working) config.gdb. Move readline
2515 Fri May 17 12:49:56 1991 Per Bothner (via gnu at cygint.cygnus.com)
2517 * dbxread.c (read_struct_type): Try to handle g++ version 1 MI
2519 * infptrace.c (fetch_registers): no result, since now void.
2520 * tconfig/news: target depends on m68k-tdep too.
2522 Fri May 17 14:40:14 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
2524 * Makefile.dist: added readline/inc-*.texinfo to dependencies for
2527 * readline/inc-history.texinfo, readline/inc-readline.texinfo:
2528 applied various small fixes due to or inspired by RMS comments
2530 * doc/gdb.texinfo: finished using all RMS comments, save those for
2531 appendices on readline and cmd history (which are in other source
2534 Thu May 16 18:06:05 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
2536 * doc/gdb.texinfo: (1) Updated w/ref to RMS comments through
2537 chapter 9; (2) documented 'break' command's menu mode for
2538 overloaded names, in response to hgs problem report C++ p-31
2540 Wed May 15 11:02:48 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
2542 * doc/gdb.texinfo: (1) better introductory example; (2) more
2543 consistent use of @code, @samp, @file, @kbd throughout; small
2544 cleanups to first three nodes; (3) new "Contributors" node;
2545 (4) Appendix, Renamed Commands; (5) divert specialized startup
2546 instructions to "Targets" chapter for generic manuals, while
2547 leaving them up front for manuals specific to specialized
2548 environments; (6) apply fixes from RMS comments through chapter 4.
2550 * pretex.m4: modify explanatory text slightly (and redefine
2551 "regexp") to keep GNU m4 from complaining. (It still crashes
2552 later, but one step at a time...)
2554 Wed May 15 10:32:12 1991 John Gilmore (gnu at cygint.cygnus.com)
2556 * readline/readline.c (update_line): Avoid dereferencing a pointer
2557 before comparing it to its bounds. Saber caught this.
2558 (init_terminal_io): Don't set BC from the "pc=" termcap variable,
2559 and only set PC if tgetstr returned non-null. Saber caught this.
2561 Tue May 14 16:29:53 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)
2563 * Makefile.dist: put gdb.dvi stuff (updated to use M4 preprocessor
2564 stuff for config manual) here where it counts; updated
2565 to use new subdir structure (gdb/doc/).
2567 * Makefile: generated from above via
2571 * gdbint.texinfo: added instructions on generating gdb.info* files
2572 locally for release. These are ordinary info
2573 files, formatted from gdb.texinfo (via gdb-all.texinfo, see
2574 Makefile)---but due to use of texinfo 2, can't count on makeinfo
2575 to generate these, so we distribute them already formatted.
2577 * gdb.texinfo: included full Info node and menu crud (as generated
2578 by C-u M-x texinfo-master-menu using the texinfo-2 elisp code).
2580 * Makefile: updated "gdb.dvi" target to use M4 preprocessor;
2581 put in comments-for-future gdb.info target (one day makeinfo will
2584 Tue May 14 13:51:36 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)
2586 * gdb.texinfo: Updated to include new or old undocumented
2587 commands, at least the following (perhaps some others I forgot to
2588 record): info f, info float, info path, info program, info s, info
2589 set, info source, info terminal, info types, info user, set/show
2591 Also covered all recent GDB command renames for v4.
2593 Mon May 13 14:57:46 1991 John Gilmore (gnu at cygint.cygnus.com)
2595 * mipsread.c: Rather than keeping count of how many symtabs
2596 and psymtabs we have, for sorting purposes, count them when
2597 we need to sort. This fixes bug in rereading of symbol tables.
2599 Fri May 10 15:43:33 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)
2601 * infcmd.c: renamed "info path" to "show paths"

2616 symtab.h, target.c, target.h: Lint.
2617 * core.c: setup and select frame after reading shared libs,
2618 else reading shared libs will clobber them. Lint.
2619 * utils.c (error): Force out any buffered wrap text.
2621 Fri May 3 22:01:56 1991 John Gilmore (gnu at cygint.cygnus.com)
2623 * remote.c: Remove decls of memory_insert_breakpoint
2624 and memory_remove_breakpoint, no longer used. (Suggestion of
2627 * Makefile.dist: use ${subdir} in paths of BFD and LIBIBERTY,
2628 to make it easier to interface to "configure"'d libraries.
2630 Fri May 3 13:10:01 PDT 1991 Roland Pesch (pesch at fowanton.cygnus.com)
2632 * valprint.c: introduce "set p", "set pr", "show p" and "show pr" as
2633 aliases for set/show print.

3184 * dbxread.c (read_dbx_symtab): Allow N_SOL to cleanly take us back
3185 to the main file, as well as to include files. Also, put global
3186 functions into the global psymtab, to make "i fun" work.
3187 (end_psymtab): Free named symtabs and psymtabs for a file, once a
3188 new psymtab for it has been read.
3189 * coffread.c (end_psymtab): Free named symtabs and psymtabs for
3190 a file, once a new symtab has been read for it.
3191 * mipsread.c: FIXME. We need to do the same for MIPS, but it
3192 looks harder to determine the top-level block before it's been
3193 queued to the psymtab list.
3195 * symfile.c (symbol_file_add): Use filtered printing and wrap it.
3196 If we have wiped out any old symbol tables, clean up at end of

3200 * symtab.h (GLOBAL_BLOCK, STATIC_BLOCK, FIRST_LOCAL_BLOCK): New
3201 defines for the blocks of a blockvector that contain global and

3211 * symtab.c (list_symbols): Process the first symbol of the
3212 static psymbols list.
3213 (types_info): Restore this function from its untimely #if 0.
3214 It's not perfect, but it is better than nothing.

3226 * symmisc.c (free_named_symtab): Make it work, in its current

3230 * symfile.h: free_named_symtab now returns an int.
3232 Mon Apr 8 23:57:43 1991 John Gilmore (gnu at cygint.cygnus.com)
3234 * dbxread.c (dbx_symfile_read): Initialize psymbol list if this
3235 is the first symbol read, even if not mainline.
3236 (dbx_psymtab_to_symtab): symfile might be zero, cope.
3237 * exec.c (exec_ops): Add_syms_addr is valid in our tvec.
3238 (set_section_command): New command ("section xxx yyy" -- should
3239 be renamed to "set section xxx yyy" FIXME) which sets the
3240 base address of a section of the exec file, overriding the
3241 virtual address that BFD reports.
3243 Fri Apr 5 17:14:39 1991 John Gilmore (gnu at cygint.cygnus.com)
3245 * exec.c: Add add_syms_addr_command to exec_ops, so you can

3250 * tm-i386v.h (FLOAT_INFO): Don't define it, since the code
3251 for printing the float info is host-dependent, not
3252 target-dependent. FIXME.
3253 * i386-pinsn.c: Move #includes to top, remove useless ones.
3254 * i386-tdep.c: Don't bother including <.../reg.h> since we
3255 don't use it (and it doesn't exist on host systems).
3257 * ieee-float.c (ieee_extended_to_double): Convert NaN to Inf.
3258 Convert negative numbers properly.
3259 (ieee_test): Make numbers really random; fix format arg.
3261 * infcmd.c (attach_command, detach_command): Don't repeat on CR.
3262 * core.c (core_detach): Unpush core_ops, which might not be on
3263 top. We used to just pop the top, which broke things. Don't
3264 need dont_repeat() any more.
3265 (core_file_command): Psst! Don't repeat it.
3266 * remote-nindy.c (nindy_detach): Don't need dont_repeat() now.
3267 * expprint.c (print_subexp): Avoid switch fallthru on
3268 BINOP_ASSIGN_MODIFY, so we can print += and such.
3269 * frame.h: Fix typo.
3270 * inflow.c (kill_command): After killing inferior, print our
3271 current frame in the core file, if we have one.
3272 (generic_mourn_inferior): When inferior dies, either select
3273 the current frame (in the new target, e.g. core file), or
3274 set both the current and selected frames to NULL.
3276 Changes from Peter Schauer.
3278 * infptrace.c: Avoid <sys/ptrace.h> on USG.
3280 * Make all file names fit in 14 characters (sigh and damn!):
3281 mv hp300hpux-xdep.c hp300ux-xdep.c
3282 mv symmetry-xdep.c symm-xdep.c
3283 mv symmetry-tdep.c symm-tdep.c
3284 mv convex-opcode.h convx-opcode.h
3285 mv tm-vxworks960.h tm-vx960.h
3286 mv tm-vxworks68.h tm-vx68.h
3287 mv Makefile.srcdir Makefile.sdir
3288 mv gdb-int.texinfo gdbint.texinfo
3289 mv remote-sa.m68k.shar rem-m68k.shar
3290 mv remote-multi.shar rem-multi.shar
3291 * Makefile.dist, README, config.gdb, convex-pinsn.c,
3292 tconfig/symmetry, tconfig/vxworks960, tconfig/vxworks68,
3293 xconfig/hp300hpux, xconfig/symmetry: Change names to shorter
3296 * command.c (user_info_1, user_info): New command for listing
3297 the user-defined commands.
3299 Wed Apr 3 15:00:26 1991 John Gilmore (gnu at cygint.cygnus.com)
3301 * dbxread.c (really_free_pendings): Clear file_symbols
3302 and global_symbols after freeing them; otherwise, running
3303 this function twice (if it appears twice on the cleanup
3304 chain), we try to free things twice.
3306 * dbxread.c (read_dbx_symtab): Calculate end_of_text_addr
3307 based on text_addr (the address of text in core), not on addr (the
3308 offset between text in the .o file and in core). This change
3309 is from Peter Schauer.
3311 * main.c: Define ALL_CLEANUPS as a cast of zero.
3312 (return_to_top_level): Use it.
3313 (main): Do all cleanups after each command run as part
3314 of the gdb startup sequence. Also do all cleanups before
3315 entering the command loop, and every time we exit the command
3316 loop and reenter. Before, the cleanups from the startup sequence
3317 were being left undone until the first error!
3318 (command_loop): Rename do_nothing cleanup to command_loop_marker
3319 so we can see it easily when examining the cleanup chain.
3320 (init_signals): Add another do_nothing for signal handling.
3321 (quit_command): Only try to kill target if it has execution.
3322 Problems in the target stack got us into a state where
3323 inferior_pid was nonzero but none of the targets had execution.
3324 In this state you couldn't exit gdb.
3326 * dbxread.c: Two changes from Peter Schauer.
3327 (echo_command): Fflush output after an echo command.
3328 (show_history): Pass all args to cmd_show_list.
3330 * utils.c (init_malloc): Call mtrace to turn on tracing
3331 if the environment variable MALLOC_TRACE is set to a file name.
3332 * mtrace.c: Add source file which provides a log of every malloc,
3333 free, and realloc to a trace file.
3334 * mtrace.awk: Add source file which analyzes the trace file.
3335 * Makefile.dist (GNU_MALLOC, MALLOCSRC): Add mtrace.{c,o,awk}.
3336 (VERSION): Roll to 3.94.3.
3338 * breakpoint.c (breakpoint_1): Add a space to "i watch" output.
3339 (check_duplicates): Don't bother with watchpoints.
3340 (set_raw_breakpoint): Comment about danger of this routine.
3341 (watch_command): Parse and eval all args before calling
3344 * solib.c (find_solib): Avoid error in referencing memory to
3345 see if any more shared libraries have been added. This is
3346 particularly useful if the target has terminated. Bug reported
3349 Changes from Peter Schauer <pesrem@regent.e-technik.tu-muenchen.de>
3350 in bringing up 3.94.2 on the Sun-3.
3352 * Makefile.dist: Include CFLAGS in rule for cplus-dem.o.
3353 * breakpoint.c (enable_breakpoint): Check for valid watchpoint
3354 expression (in scope) before reenabling watchpoint.
3355 * signame.c (init_sigs): Add missing declaration of i, fix
3356 sys_siglist declaration.
3357 * source.c (list_command): Fixed range computation to use
3359 * stack.c (backtrace_command): Do not allow command if target has
3360 no stack, print informative error message.
3361 * target.c (target_command): Do not write into command line
3362 because this fails if the target command is used in a user defined
3363 command. [This change was enhanced by gnu to support any-
3364 unique-prefix matching on target names.]
3365 * valops.c (value_struct_elt): Avoid infinite loop on an
3366 erroneous attempt to print the member of function (try p main.p).
3368 Mon Apr 1 17:05:45 1991 John Gilmore (gnu at cygint.cygnus.com)
3370 * expread.y (name_no_typename): Avoid reduce/reduce errors
3371 caused by ambiguity in handling NAME_OR_INT and NAME_OR_UINT.
3372 Since the GDB parser really doesn't use name_no_typename in a
3373 name-only context, the parser can't tell the diff between
3374 names and numbers here. Avoid allowing a name_no_typename
3375 to be a NAME_OR_*INT to resolve the conflict.
3377 Sun Mar 31 20:12:07 1991 John Gilmore (gnu at cygint.cygnus.com)
3379 Bugfixes from Mark Fox (markf@wrs.com) (test=testField.c):
3381 * valprint.c (val_print_fields): bitfield printing didn't handle
3382 byte order. Indirect through a few more fns to cope.
3384 * values.c (modify_field): also cope with byte order.
3386 Sat Mar 23 10:02:21 1991 John Gilmore (gnu at cygint.cygnus.com)
3388 Cleanup for release 3.94.2:
3390 * Makefile.dist: Pull REMOTE_OBS. Fix saber includes for BFD
3391 include files. Roll version to 3.94.2.
3393 * coffread.c (init_stringtab): Read length into unsigned char
3394 array before swapping; don't assume 32-bit longs.
3396 * target.c (target_info): Don't bother with get_sym_file, just use
3397 the symfile global variable.
3398 * symtab.h, symfile.c (get_sym_file): Delete it.
3400 * dbxread.c (dbx_symfile_init): Don't depend on long == 4 bytes.
3401 (define_symbol): Set symbol line number to 0 if not gcc-compiled.
3402 (read_type): Replace one more error() with complain().
3404 * mipsread.c (parse_partial_symbols): Replace printf with complain.
3406 * i960-tdep.c: Fix copyright attribution.
3408 * config.gdb: Quote all backquotes in doublequotes. You can
3409 quote me on that. BSD 4.4 shell found this one.
3411 * infptrace.c (throughout): The third argument to ptrace is an
3414 * infrun.c (wait_for_inferior): When program has terminated, we
3415 have to call target_terminal_ours before we pop that target off
3416 the stack (e.g. before a call to target_kill or
3417 target_mourn_inferior). This fixes problem where a program
3418 terminates, then GDB stops for (tty output) and you have to type
3419 "fg" to the shell to resume it. FIXME: This code for what to
3420 do after termination really should be in normal_stop instead.
3422 * gdbcore.h (read_memory_check): Change declaration; it changed
3425 * terminal.h: Include <sgtty.h> before <sys/ioctl.h>, since in BSD
3426 4.4 prereleases, this avoids a bug in their sgtty compatability
3428 * remote.c: Use terminal.h rather than hand-rolling the same.
3430 * signame.c, signame.h (psignal): Arg is unsigned, not int.
3431 * utils.c (strsave, strstr): Fix arg types.
3432 * valprint.c (val_print): lint
3434 MIPS symbol table support from Per Bothner:
3436 * symfile.c (symtab_fns): Remove initializer table that needs to
3437 be hacked for each new symbol file format supported.
3438 (add_symtab_fns): New function, chains symbol table
3439 handlers into the global list.
3440 (symfile_init): Search this list.
3441 * symfile.h: Add next pointer, declare add_symtab_fns.
3442 * coffread.c (_initialize_coffread): Call add_symtab_fns.
3443 * dbxread.c (_initialize_dbxread): Call add_symtab_fns.
3445 * mipsread.c (psymtab_to_symtab_1): return void instead of (struct
3446 symbol *). Thus, we no longer need the hack to trash
3447 pst->filename. Good, since that hack confused code in symfile.c!
3449 (reorder_symtabs, destroy_all_symtabs): Removed static
3450 all_symtabs, which was used to qsort symtabs in reorder_symtabs.
3451 Instead, the latter now uses a temporary array (stack-allocated
3452 from an obstack, and then freed).
3454 (parse_symbol): Added a hack to fix up BLOCK_{START,END} if they
3455 haven't been set in the outermost stBlock of a procedure. This was
3456 a problem with f77 binaries on Ultrix 4.?.
3458 (new_symtab, new_symbol, new_type): Continue changing code to use
3459 obstacks more and otherwise conform to dbxread internal style.
3460 Made the free_code of symtabs be free_linetable (as in dbxread)
3461 instead of free_contents. This implies memory leaks when reading
3462 a new symbol table, until the conversion is finished. Did change
3463 (struct symbol) and (struct type) to be allocated on the
3464 symbol_obstack. Blocks and blockvectors are among the things
3467 * mipsread.c (parse_partial_symbols, parse_fdr): It hasn't been
3468 tested much, but it solved one problem (reported by Meissner), and
3469 cleans up some other things. The problem happened when an
3470 included file contains actual code (functions) and not just
3471 definitions. The mips coff is a little inconvenient there, since
3472 it may cause a procedure to be mapped to the wrong psymtab.
3474 * mips-tdep.c (heuristic_proc_desc): Minor cleanup.
3475 * mips-xdep.c (fetch_core_registers): Minor cleanup. FIXME,
3476 this will need work for the new core paradigm.
3478 Opcode patches from the net:
3480 * mips-opcode.h: fix incorrect disassembly of the mfc1, cfc1, and
3481 ctc1 instructions. Also, the cvt.d.w and cvt.s.w instructions were
3482 missing altogether - they are added here. From Bruce Bauman.
3483 * mips-opcode.h: The low mask for C0 instructions was too small.
3484 From Garrett Lau. I modified the fix to check the entire 32-bit
3487 * ns32k-opcode.h: Fix opcodes for deiw and deid. From Bruce
3490 Thu Mar 21 12:56:46 1991 John Gilmore (gnu at cygint.cygnus.com)
3492 Roll in changes from Per Bothner (Tue, 25 Sep 90 11:11:04):
3494 * dbxread.c (read_type): Pointer subtraction (value_sub in
3495 valarith.c) sometimes failed because the types of the
3496 pointers being subtracted were not identical.
3497 These differed because dbxread.c was allocating pointer types
3498 using dbx_alloc_type+smash_to_pointer_type instead of
3499 lookup_pointer_type. I failed to find a justification for the
3500 former, so I changed it to use the latter. Similarly, I
3501 replaced smash_to_function_type by lookup_function_type,
3502 and smash_to_reference_type by lookup_reference_type.
3504 * mipsread.c (parse_symbol, upgrade_type, parse_procedure,
3505 _initialize_mipsread): corresponding changes.
3507 * symtab.c (smash_to_{pointer,reference,function}_type): eliminate.
3509 * source.c (mod_path): Do tilde_expand on each component of the path,
3510 rather than on the (list of) paths as a whole.
3511 (print_source_lines): Set first_line_listed in addition to
3512 current_source_symtab and current_source_line. If the source was
3513 not findable, after a "dir" command to fix the problem,
3514 a "list" would get the wrong lines.
3516 While I was there... (gnu):
3518 * dbxread.c (read_type): Change error to complaint.
3520 Thu Mar 21 12:56:46 1991 John Gilmore (gnu at cygint.cygnus.com)
3522 First attempt at detailed understanding of symbol table memory alloc.
3524 * dbxread.c (dbx_symfile_read): Free our string table if we
3525 aren't the mainline. Free the "info" struct since we're done with
3527 (init_psymbol_list): Free any previously allocated psymbol lists.
3528 (): FIXME: Should realloc-down the psymbol lists when done reading
3529 the main symbol file?
3531 * symmisc.c (free_symtab): Free fullname field too.
3533 * xm-hp300hpux.h (USG): #undef then #define so Makefile can -D.
3534 (REGISTER_ADDR): Make result type unsigned int.
3536 * xconfig/{i386*,hp300hpux,altosgas,altos}: All config files that
3537 define REGEX must also define REGEX1 (its dependency).
3539 Tue Mar 19 21:28:57 1991 John Gilmore (gnu at cygint.cygnus.com)
3541 * tconfig/i960: No longer works, points you at vxworks960 or
3544 * xgdb.c, XGDB-README: Remove file. Users can get the much
3546 * Makefile.dist: Remove all trace of xgdb.
3548 * breakpoint.c (breakpoint_1): Pass demangle arg to
3549 print_address_symbolic.
3550 (clear_breakpoints): Remove unused function.
3551 (breakpoint_re_set_one): Guts of breakpoint_re_set.
3552 (breakpoint_re_set): Use catch_errors to do them all anyway.
3554 * gdb-int.texinfo (Host versus Target): Add section on what is
3555 a "host" feature versus what is a "target" feature.
3557 * infcmd.c (path_command, path_info): Handle the PATH variable
3558 (object search path) as conveniently as the source search path.
3559 * environ.c (set_in_environ): Set some vars in GDB's environment,
3560 in addition to the child's. PATH, G960BASE, G960BIN for starters.
3561 * source.c (mod_path): New function, from guts of
3562 directory_command, modifies a path. Used by path_command.
3563 (directory_command): Call it.
3564 * defs.h (strsave): Declare.
3566 * utils.c (sevenbit_strings): Add new printing option.
3567 (printchar): Use it.
3568 (strsave): Provide this handy helper routine.
3569 (set_width_command): Rename set_screen_width_command.
3570 (_initialize_utils): "set screen-width" => "set width";
3571 "set screen-height" => "set height"; add sevenbit-strings.
3573 * infcmd.c (do_registers_info): Print floating point registers
3574 in raw hex as well as float format, regardless of whether it is
3575 a "virtual" convertible register.
3576 * tm-sparc.h (PRINT_REGISTER_HOOK): Print every pair of float
3577 regs as a double, just in case it's being used that way.
3578 * values.c (unpack_long): Comment on array/function coercion.
3579 (unpack_double): Argument is in target byte order now. For
3580 integer arguments, just call unpack_long and float the result.
3581 * m68k-tdep.c: include defs.h for "const" handling.
3582 * remote-nindy.c: Use ieee-float stuff.
3583 (nindy_fetch_registers): Unpack double regs to host double, then
3585 (nindy_store_registers): Pack extendeds to host double, flip
3586 around by misusing unpack_double, send as target double.
3588 * tm-vxworks68.h (FRAME_CHAIN): Handle current frame pointer of
3589 zero, as when stopped at the first instruction of a process.
3591 * blockframe.c: Fix filename in comment (param.h => tm.h).
3592 * sparc-tdep.c (skip_prologue): More explicit nudging comments.
3593 * tm-68k.h: Fix typos.
3595 Fri Mar 15 01:09:34 1991 John Gilmore (gnu at cygint.cygnus.com)
3597 Changes from a bringup on the DEC Vax under Ultrix 4.0.
3599 * coredep.c (fetch_core_registers): Pass end-address of register
3600 section to register_addr as expected. Don't call supply_register
3601 if we'd just pass it garbage.
3603 * dbxread.c (read_dbx_symtab): Skip N_NSYMS on Ultrix.
3605 * exec.c (xfer_memory): Use boolean xfer_fn result, not int.
3607 * target.c (push_target, target_info): Cast enums to int for < or
3610 * stack.c (print_frame_info): Identify source file & line
3611 even if we can't print it.
3613 * xm-vax.h (MISSING_VPRINTF): No longer missing in Ultrix V4.0.
3615 Sat Mar 9 10:08:20 1991 John Gilmore (gnu at cygint.cygnus.com)
3617 Clean up IEEE floating point support.
3619 * ieee-float.h: New file.
3620 * ieee-float.c: Write real routines to convert between host
3621 doubles and various target IEEE extendeds.
3622 * m68k-xdep.c: Eliminate assembler code for extended floats.
3623 * xconfig/{3b1,altos,altosgas,hp300bsd,isi,news,news1000,sun2os3,
3624 sun2os4,sun3,sun3os3,sun3os4}: Eliminate use of m68k-xdep.o.
3625 * tm-i960.h, tm-68k.h (REGISTER_CONVERT_TO_VIRTUAL,
3626 REGISTER_CONVERT_TO_RAW): Use ieee_extended_to_double and
3627 double_to_ieee_extended.
3628 * i960-tdep.c: Define ext_format_i960.
3629 * m68k-tdep.c: Define ext_format_68881.
3630 * sparc-tdep.c: Define ext_format_sparc, though unused.
3631 * Makefile.dist (HFILES): Add ieee-float.h.
3632 * inftarg.c: #include "ieee-float.h" for the REGISTER_CONVERT
3635 Obsolete the "coffstrip" program in favor of using BFD's strip.
3637 * nindy-share/coffstrip.c: Remove file.
3638 * nindy-share/nindy.c (coffstrip): Routine to run bfd_strip.
3639 * Makefile.dist: Remove references to nindy-share/coffstrip.c.
3640 * tconfig/nindy960: Remove reference to coffstrip.o.
3642 * Makefile.dist: Roll version number to 3.94.1 (not yet final).
3644 Wed Mar 6 09:56:45 1991 John Gilmore (gnu at cygint.cygnus.com)
3646 * symfile.h: Add symfile_bfd, common between dbxread and coffread.
3647 * dbxread.c: Remove static symfile_bfd.
3648 * infcmd.c (do_registers_info): Add PRINT_REGISTER_HOOK, though
3650 * inftarg.c (child_detach): Pop the child_ops vector if the
3651 detach is successful.
3652 * remote-nindy.c (nindy_create_inferior): Don't push a new
3653 nindy_ops since nindy uses the same one for execution and memory
3655 * core.c (core_ops): Use child_attach and child_create_inferior
3656 rather than default attach and create_inferior functions.
3658 Handle floating point registers in core files.
3660 * sparc-xdep.c (fetch_core_registers): Rewrite for float support.
3661 * sun3-xdep.c (fetch_core_registers): Rewrite for float support.
3662 This version untested since BFD doesn't yet support sun3 core
3664 * hp300hpux-xdep.c: Rewrite fetch_core_registers to new calling
3665 conventions. Fix comments and style. This version has not
3666 been compiled yet, since we have no HP inhouse.
3667 * core.c (get_core_registers): Look for two sections, ".reg"
3668 and ".reg2", and pass both to fetch_core_registers sequentially.
3670 Revise directory path yet again.
3672 * source.c (forget_cached_source_info): Not static any more.
3673 (init_source_path): New default source path is "$cdir:$cwd".
3674 (dir_command): Handle variable arguments ($cdir, $cwd).
3675 (source_info): Print "Compilation directory" rather than
3676 "Originally compiled in" to remind people of $cdir.
3677 (openp): If the path contains $cwd, use current directory.
3678 (open_source_file): If compilation directory is known, replace
3679 first $cdir in path with the compilation directory.
3680 (print_source_lines): Even if we can't print the lines, set the
3681 current symtab and line for future commands like "info source" or
3682 "breakpoint". Also, error message now contains the file name,
3683 line number, and file access error message.
3684 (_initialize_source): Fix help text to describe changes.
3685 * main.c (cd_command): Forget cached source info when we chdir.
3686 * utils.c (strstr): Add simple implementation.
3688 Tue Mar 5 01:41:40 1991 John Gilmore (gnu at fowanton.cygnus.com)
3690 * coffread.c (read_one_sym, init_linetable, init_stringtab):
3691 Byte-swap COFF symbol tables if necessary when reading them in.
3692 Use complain() to replace error message in one spot. Needs
3693 corresponding change in bfd/coff-code.h to make some symbol
3694 swapping routines non-static.
3696 Mon Mar 4 00:53:40 1991 John Gilmore (gnu at cygint.cygnus.com)
3698 Merge changes from Eirik Fuller, for UTek.
3700 * defs.h (errno): Add declaration.
3701 * altos-xdep.c, arm-xdep.c, convex-xdep.c, gould-xdep.c,
3702 hp300hpux-xdep.c, infrun.c, inflow.c, infptrace.c, i386-tdep.c,
3703 i386-xdep.c, pyr-xdep.c, mips-xdep.c, remote-eb.c, remote-nindy.c,
3704 remote-vx.c, source.c, standalone.c, stuff.c, sun386-xdep.c,
3705 symmetry-tdep.c, symmetry-xdep.c, umax-xdep.c, utils.c: Eliminate
3706 declarations of errno.
3708 * remote-eb.c: Define B19200 and B38400 as EXTA and EXTB.
3710 * remote-vx.c: Include <sys/time.h> for UTek; Sun gets it via
3711 <rpc/rpc.h> and <rpc/types.h>.
3713 Sat Mar 2 15:47:55 1991 John Gilmore (gnu at cygint.cygnus.com)
3715 * i960-tdep.c (examine_prologue): Add new argument limit,
3716 which stops the scan at the end of the prologue, or at the PC.
3717 This fixes a problem where it walks down into the code for the
3718 user's statements if that code looks like function prologues.
3719 Mark Fox and I have been bouncing this code back and forth, making
3720 small changes to it. Callers changed to match.
3722 Tue Feb 26 01:47:07 1991 Cygnus John Gilmore (cygnus at yuba)
3724 Cleanup for gdb-3.94 release final:
3726 * Makefile.dist: Remove remote-vx.c, remote-nindy.c, and all
3727 the .c files from vx-share and nindy-share, from the various
3728 macros, since they are not found via ALLDEPFILES.
3729 (SFILES): Add tm-i960.h.
3730 (alldeps.mak rule): Break out ALLDEPFILES_MAINDIR and
3731 ALLDEPFILES_SUBDIR. List all the nindy and vxworks subdir files
3733 (TAGFILES_MAINDIR): Change ALLDEPFILES to ALLDEPFILES_MAINDIR.
3734 (gdb.tar.Z): Use ALLDEPFILES_SUBDIR as well as SFILES_SUBDIR.
3736 Mon Feb 25 16:02:35 1991 Cygnus John Gilmore (cygnus at oldman)
3738 * am29k-tdep.c: Add contribution line.
3739 (examine_prologue): Cache information about function prologues in
3740 the misc-function-vector to avoid lots of references over the
3741 serial line while examining instructions.
3743 * core.c (core_close): New function made from cleanup_core.
3745 * core.c, exec.c, inftarg.c, remote-eb.c, remote-nindy.c,
3746 remote-vx.c, remote.c, target.c, target.h,
3747 Update target_ops vector to add attach, close, and load entries.
3748 Use add_syms_addr_command, not add_file_addr_command, for
3749 add_file. Break out close routine from existing code.
3751 * dbxread.c (really_free_pendings): Don't free pending_blocks;
3752 they are in an obstack.
3753 (read_dbx_symtab): Relocate end_of_text_addr in the psymtab.
3755 (define_symbol): Add symbol type parameter; change callers;
3756 pass type parameter to DBX_PARM_SYMBOL_CLASS macro to allow
3757 it to influence the symbol class on the i960.
3758 (define_symbol): Swap LOC_CONST's into target byte order.
3760 * exec.c (exec_close): New function.
3761 (exec_file_command): Call it.
3763 * findvar.c (read_relative_register_raw_bytes): Doc byte order,
3764 Fix byte order of frame pointer.
3765 (read_var_value): Result of 0 if var's value can't be found,
3766 e.g. missing FRAME_ARGS_ADDRESS. Byte-swap LOC_CONST and
3767 LOC_LABEL values to target order. Add LOC_LOCAL_ARG.
3768 (locate_var_value): Use read_var_value and use its lazy address
3769 as the location of the var's value. Lint.
3771 * i960-pinsn.c (next_insn): Add routine from vxgdb for scanning
3774 * i960-tdep.c (arg_address, i960_frame_find_saved_regs): Remove
3775 obsolete Intel versions in favor of vxgdb versions.
3776 (check_host, byteswap, byteswap_val, reorder_val): Eliminate
3777 code dealing with byte order of values, which Intel did in host byte
3778 order rather than gdb-4's target byte order.
3779 (i960_frame_chain_valid): Move to nindy-tdep.c.
3780 (examine_prologue, skip_prologue, frame_find_saved_regs,
3781 frame_args_address, leafproc_return, saved_pc_after_call,
3782 pop_frame): Add vxgdb versions from Mark Fox.
3783 (examine_prologue, frame_struct_result_address): Add code
3784 to deal with the saved value of G13 (struct return address
3786 (frame_args_address): Modify Mark's version to prefer the
3787 saved value over the current value in the topmost frame.
3788 Cache result in the frame info to avoid performance hair in
3790 (print_fault): Add gdb960 code for printing faults.
3791 (_initialize_i960): Actually call check_host.
3793 * ieee-float.c (ieee_extended_to_double, ieee_double_to_extended):
3794 add stub routines. FIXME, these currently just return zero!
3796 * infcmd.c (program_info): Use PRINT_RANDOM_SIGNAL.
3797 (attach_command): Call target_attach, not target_open, now.
3799 * infrun.c (normal_stop): Make global, not static, for vx_attach.
3800 (child_attach): Rename from child_open.
3801 (wait_for_inferior): Use PRINT_RANDOM_SIGNAL. If stop_pc is zero,
3802 don't confuse it with a zero step_resume_break_address.
3804 * inftarg.c (child_detach): Eliminate inferior_pid test.
3805 (child_files_info): Clean up message a bit.
3806 (child_ops): Use child_attach, not child_open, to attach.
3808 * mem-break.c: #ifdef out the whole file if BREAKPOINT is not
3809 set (e.g. on VxWorks or NINDY). Move read_memory_nobpt from
3810 findvar.c to here, since it depends on the contents of the
3811 shadow_contents of breakpoints, but keep if #if 0 since it is
3814 * nindy-tdep.c: New file, contains nindy_frame_chain_valid, moved
3817 * printcmd.c (address_info): Handle LOC_LOCAL_ARG. Lint.
3818 (ptype_command, display_command): Eliminate have_inferior_p and
3819 have_core_file_p in favor of target_has_stack or
3820 target_has_execution.
3821 (print_frame_args): Handle LOC_LOCAL_ARG. Eliminate duplicate
3822 code for actually finding the values of arguments, though we still
3823 keep track of the maximum stack offset for use in printing unnamed
3824 arguments. Handle missing FRAME_ARGS_ADDRESS.
3826 * remote-nindy.c (i960_print_fault): Move to i960-tdep.c.
3827 (struct nindy_regs): Define registers passed to/from nindy.
3828 (nindy_fetch_registers, nindy_store-registers): Translate between
3829 nindy and GDB formats for the registers.
3830 (dcache_init): Statically allocate the cache, since it was being
3831 allocated by a malloc that was never freed anyway.
3832 (nindy_create_inferior): Error, not core dump, if no exec file.
3833 (nindy_before_main_loop): Use target_load, not target_add_file.
3835 * remote-vx.c (net_load): Specify large timeout for load
3836 requests. Allow user to break out with INTERRUPT.
3837 (net_break): Remove useless code, clean up. Change callers.
3838 (parse-args, skip_white_space, find_white_space): Clean up arg
3839 parsing to cope with quoted strings.
3840 (net_wait, net_quit): Never call error, just return status.
3841 (vx_read_register, vx_write_register): Cleanup status checking.
3842 #ifdef the code based on which CPU we are using (960 or 68k),
3843 FIXME, this should be completely general but it isn't yet.
3844 (vx_xfer_memory, vx_resume): Cleanup status checking.
3845 (vx_run_files_info): Improve message.
3846 (vx_load_command): Renamed from vx_add_file_command. Allow load
3848 (net_ptrace): Remove unused routine.
3849 (vx_wait): Adopt code from vxgdb960 to cope with broken
3850 connections to target machine and prompt to disconnect. Remove
3851 debug printouts. Map some EVENT_'s to SIGnals.
3852 (add_symbol_stub, vx_open): Print names of object files we found,
3853 and "ok" if we read their symbols OK. Clarify output in general.
3854 (vx_attach, vx_detach, vx_kill): Add these commands.
3855 (vx_convert_from_virtual, vx_convert_to_virtual): Simplify.
3856 (vx_run_ops): Turn off all_mem, to avoid spurious msg in the
3857 "info files" output, and create_inferior, since we already have
3860 * stack.c (frame_info): Replace Frame_unknown with 0.
3861 (print_frame_arg_vars): Handle LOC_LOCAL_ARG.
3862 (return_command): Pop until the PC matches as well as the FP,
3863 so it works even if the FP is shared with another function,
3864 as in "frameless" or "leaf" procedures.
3866 * symfile.c (load_command): renamed from add_file_target_command.
3867 (add_syms_addr_command): renamed from add_file_addr_command.
3868 (add_syms_command): Stub to call target_add_syms.
3869 (_initialize_symfile): Change command names and descriptions,
3870 add-file => add-syms, and load from alias to its own command.
3872 * target.c (kill_or_be_killed, maybe_kill_then_attach,
3873 maybe_kill_then_create_inferior): Default for attempts to start
3874 a process, if one is already running, is to ask about killing
3875 it and retry if yes.
3876 (upstack_create_inferior): #if-0 it, strata obsolete it.
3877 (push_target, unpush_target, pop_target): to_close() a target
3878 before unstacking it.
3879 (target_info): Renamed from target_files_info.
3880 (_initialize_targets): Rename "i files" as "i target", accessible
3883 * target.h: Improve comments about the target_ vectored routines.
3885 * tm-i960.h: Remove NINDY-specific stuff to tm-nindy960.h.
3886 Convert commenting style to standard GNU style.
3887 (DBX_PARM_SYMBOL_CLASS): allow LOC_LOCAL_ARG's to be recognized.
3888 (SKIP_PROLOGUE): No longer a no-op.
3889 (SAVED_PC_AFTER_CALL): Now handles leaf procedures.
3890 (*_REGNUM): Sort register numbers.
3891 (REGISTER_BYTES, REGISTER_BYTE, REGISTER_RAW_SIZE,
3892 MAX_REGISTER_RAW_SIZE, REGISTER_CONVERTIBLE,
3893 REGISTER_CONVERT_TO_VIRTUAL, REGISTER_CONVERT_TO_RAW): Float regs
3894 are now 10 byte extendeds, not 8 byte doubles.
3895 (FRAME_CHAIN_VALID): Make this config-dependent, since it differs
3896 for nindy versus vxworks targets. FIXME, this should possibly go
3897 in the target vector.
3898 (EXTRA_FRAME_INFO, INIT_EXTRA_FRAME_INFO): Cache both
3899 frame_saved_regs and arg pointer with each frame.
3900 (FRAMELESS_FUNCTION_INVOCATION): New leafproc support.
3901 (FRAME_ARGS_ADDRESS): Use cached result.
3902 (FRAME_ARGS_ADDRESS_CORRECT): New, avoids g14 guessing.
3903 (FRAME_FIND_SAVED_REGS): Change arg to subsidiary fn.
3904 (PRINT_RAMDON_SIGNAL): Call print_fault.
3905 (POP_FRAME): Now works.
3907 * tm-nindy960.h: Break this off tm-i960.h. NINDY-specific
3908 option parsing and startup; STACK_END_ADDR, FRAME_CHAIN_VALID,
3909 BREAKPOINT, and DECR_PC_AFTER_BREAK are here.
3910 (ADDITIONAL_OPTION_HANDLER): use target_load, not
3913 * tm-vxworks960.h: Break this off tm-i960.h. VxGDB specific
3914 startup; DECR_PC_AFTER_BREAK, and FRAME_CHAIN_VALID are here.
3916 * valarith.c (value_subscripted_rvalue): Avoid handling
3917 floats and doubles specially; it gave alignment errors. Lint.
3919 * valops.c (value_of_variable, value_of_this): Error if unknown
3922 * valprint.c (print_floating): Bcopy rather than pointer-deref,
3923 to avoid alignment problems.
3924 (value_print): Handle unknown value address.
3925 (cplus_val_print): Two args are ignored; remove them. Change caller.
3926 (val_print): Use unpack_long rather than pointer-deref.
3929 (unpack_long, unpack_double): Use bcopy rather than pointer-deref
3930 to avoid alignment problems.
3931 (value_being_returned): Error if return value unknown.
3932 (set_return_value): Add bogosity warning, FIXME. *
3934 * TODO: A woman's work is never done.
3936 * Makefile.dist: Distribute REMOTE_OBS into tconfig files.
3937 Separate INCLUDE_CFLAGS for use with lint. Add LINTFILES.
3938 Add ieee-float.o to OBS.
3939 * tconfig/{nindy960,vxworks68,vxworks960}: Include the desired
3940 REMOTE_OBS remote-interface files in the TDEPFILES and TM_FILE.
3941 * tconfig/i960: FIXME. Half-merge, produce warning if config'd.
3943 Changes to generalize the VxWorks RPC protocol slightly, to handle
3944 i960 as well as 68000.
3946 * vx-share/dbgRpcLib.h (VX_SOURCE_STEP): Add.
3947 * vx-share/reg.h: Produce i960 regs #ifdef I80960
3948 * vx-share/xdr_ptrace.c: Skip FPA registers if 960.
3949 * vx-share/xdr_rdb.h: Add SOURCE_STEP struct and xdr decl.
3950 * vx-share/xdr_rdb.c: Add xdr_SOURCE_STEP routine.
3951 * vx-share/xdr_regs.c: Add xdr_regs, xdr_fp_status, xdr_ext_fp
3952 for i960. Change xdr_vectors to xdr_opaques for 68k registers,
3953 so they will move in target byte order rather than network
3954 byte order (happens to be the same).
3956 Mon Feb 25 03:41:44 1991 John Gilmore (gnu at cygint.cygnus.com)
3958 * tm-convex.h (END_OF_TEXT_DEFAULT): Remove #if 0'd block.
3960 Sun Feb 24 00:55:53 1991 John Gilmore (gnu at cygint.cygnus.com)
3963 Add contribution lines to various files, showing where they
3966 * breakpoint.c (break_insn, check_break_insn_size,
3967 read_memory_nobpt): Remove to mem-break.c.
3969 * xm-*.h, param-no-tm.h, tm-29k.h, valprint.c: Change BYTE_ORDER to
3972 * tm-29k.h (STAB_REG_TO_REGNUM): Warn user if symbol table
3973 entry has bad register number. This change is not
3974 tested in this release, FIXME.
3976 * frame.h: Eliminate Frame_unknown in favor of a simple zero.
3979 * value.h: Force value's contents field to be aligned to hold
3980 at least a double or a long long (if supported). This avoids
3981 doing bcopy's in and out of the contents field.
3983 (step_1): Avoid coredump under obscure circumstances when we
3986 * symtab.h (misc_info): Add field to misc function vector for
3987 any kind of cached information the target code desires. AMD
3988 29000 uses this to avoid repeating examine_function_prologue's.
3990 * coffread.c: Lint. Remove static symfile, read_section_header.
3991 core.c (have_core_file_p): Lint: remove.
3992 expprint.c (print_subexp): Lint.
3993 infptrace.c, valops.c, valprint.c: lint.
3995 Roll in changes from vxgdb-5.0.1:
3997 * symtab.h: Comment byte order of each address class. Add
3998 LOC_LOCAL_ARG for frame-relative args (960).
3999 expread.y: Use LOC_LOCAL_ARG where LOC_ARG is used.
4000 symtab.c, symmisc.c: ditto.
4002 * infrun.c (init_wait_for_inferior): Clear stop_signal.
4004 * remote.c (remote_resume): Error if resume with a signal.
4006 * symfile.c (prim_record_misc_function): Clear misc_info.
4007 (fill_in_vptr_fieldno): Check stub type of arg.
4009 * valops.c (value_cast): Avoid looking up names of types whose
4010 name we don't know, to prevent coredump. Sun CC produces typedef
4011 rtx and the name of *rtx is zero...
4013 Mon Feb 18 21:16:25 1991 John Gilmore (gnu at cygint.cygnus.com)
4015 Roll in changes from final AMD 29000 port (Tiemann).
4017 tconfig/am29k: Add COFF_ENCAPSULATE and TARGET=TARGET_AM29K
4018 for ../include/a.out.encap.h. This might not work now that BFD
4019 is separately compiled. Instead, BFD support for encap will have
4020 to translate machine type 29k into the right COFF_MAGIC.
4022 * infcmd.c: Remove references to inferior_pid that aren't used
4023 in actual ptrace calls; use target_has_execution, etc.
4024 (have_inferior_p): Remove function.
4025 (program_info): Print target info rather than "process number";
4026 avoid gratuitous messages unless from_tty.
4027 (run_stack_dummy, finish_command): Set proceed_to_finish.
4028 infrun.c: Remove inferior_pid refs. Decl & init proceed_to_finish.
4029 main.c: Lint. Lose have_inferior_p().
4030 inferior.h (have_inferior_p): Remove, lint.
4031 (proceed_to_finish): Add flag to ask that all regs be saved
4032 by normal_stop, for the few commands that need it, speeding up
4033 serial I/O. Add comments to stop_registers.
4035 * remote-eb.c: Remove newline from breakpoint message we grep
4036 for. Never time out when running the user program.
4040 Wed Feb 13 15:34:40 1991 John Gilmore (gnu at cygint.cygnus.com)
4042 Roll in changes from vxgdb-5.0.1:
4044 * dbxread.c (read_dbx_symtab): If we encounter a "FORTRAN COMMON"
4045 symbol in its raw form, we are processing an unlinked ".o" file.
4046 See if the target environment has assigned it an address, using
4047 target_lookup_symbol (VxWorks does), and enter it into the symtab
4050 * tm-vxworks.h (FRAME_CHAIN, FRAME_CHAIN_VALID): Override usual
4051 68k versions for a simpler version that assumes zero FP at bottom.
4052 Fixes bug of truncated stack reports.
4054 * target.h (target_lookup_symbol): Define this routine's args
4055 and result, finally.
4057 * target.c (nosymbol): Default routine for target_lookup_symbol.
4058 (target_default): Default lookup_symbol and call_function too.
4059 (files_info): Only print has_all_memory warning if a non-dummy
4062 * remote-vx.c (vx_read_register, vx_convert_to_virtual,
4063 vx_convert_from_virtual): If target does not have floating point,
4064 zero register "values", and avoid doing cross-net conversions.
4065 (vx_lookup_symbol): Rename net_lookup_symbol, add to vectors.
4066 (vx_open): Rearrange code that attaches to target and reads
4067 symbols for all loaded modules, to work if some of the modules
4068 are not accessible. Add symbol_stub() and add_symbol_stub()
4069 as callbacks from catch_errors(). Allow connect attempt to be
4070 interrupted painlessly with ^C (FIXME, there are still some bugs
4071 if the interrupt happens during symbol reading.). Print
4072 final message with puts_filtered, since symbol messages are
4077 * main.c (catch_errors): Only print errstring if non-null.
4078 (command_loop): Avoid an ioctl per command to test ISATTY.
4080 * remote-vx.c (net_load): make static; avoid sophomoric msg.
4081 (vx_xfer_memory): Return correct result!
4082 (vx_files_info): Indicate whether target has float or not.
4083 (vx_lookup_symbol): Complain, not error, if target gone.
4084 (vx_open): Print "Connected" msg before disabling immediate-quit.
4085 [FIXME: lookup_symbol and vx_open changes need testing.]
4087 target.c, remote-eb.c, inftarg.c, am29k-opcode.h, target.h,
4088 tm-29k.h, tmm-vxworks68.h, symfile.c, gdb-int.texinfo: Add
4089 contributor lines and update copyrights to 1991.
4091 Changes from an attempted H-PUX host port:
4093 * infptrace.c (PT_ATTACH, PT_DETACH): Handle HP/UX, which
4094 defines PT_ATTACH and PT_DETACH but not PT_KILL.
4095 * remote-eb.c (eb_open): Misplaced endif kills sysv H/PUX.
4096 * remote-vx.c: include <sys/time.h> for HPUX.
4097 * hp300hpux-xdep.c (fetch_core_registers): Rewrite old
4098 "core_file_command" routine to BFD regime. May not work yet.
4100 Attempted port of "gdb-3.4 Van Jacobson xgdb" to modern gdb.
4102 * xgdb.c: Replace X10 version with some VJ version.
4103 (FIXME: Its copyright assignment is not on record.)
4104 * xgdb.c: Update include files to X11R4 (Xaw crud).
4105 (xgdb_display_source, create_text_widget): fix call to
4106 get_filename_and_charpos. Rewack source window stuff for X11R4
4107 (gleaned from include files, and "nm's" of binary libraries, since
4108 I had no doc available).
4109 (append_selection, append_selection_word): Disable with FIXME
4110 since R4 changed interface here.
4111 (create_buttons): Add back the old set of buttons.
4112 (xgdb_create_window): Fix call to XtInitialize (&argc not argc).
4114 * Makefile.dist (xgdb, xgdb-init.c): Update for X11R4 on Suns.
4115 Roll VERSION to 3.94 (not yet final though).
4117 Sat Feb 9 09:46:25 1991 John Gilmore (gnu at cygint.cygnus.com)
4119 * obstack.h (obstack_ptr_grow, obstack_ptr_grow_fast,
4120 obstack_int_grow, obstack_int_grow_fast): Eliminate
4121 cast on left of assignment, which gives MIPS cc fits and is
4124 * sparc-pinsn.c (print_insn): Eliminate 'set' test, subsumed by
4125 F_ALIAS. Use printf, not fprintf, when not passing a file
4127 (compare_opcodes): Check that identical instructions have
4128 identical opcodes, complain otherwise.
4130 * sparc-opcode.h (st %fsr): Fix opcode "lose" mask. This
4131 was reported by Roland McGrath.
4132 (unimp): Only match if exactly zero instruction. (Roland)
4133 (branches and traps): Generate all variations of these
4134 instructions with macros, based on a single call that defines
4135 each condition name and its binary representation.
4136 (set): Turn on alias bit, to avoid test in sparc-pinsn.c.
4138 * valprint.c (val_print_fields): Take, and use, format parameter.
4139 This means that "p/x struct" again prints the elements in the
4140 desired format. Changed callers.
4142 * stack.c (frame_info): Use filtered output, and indicate wrap
4143 points. Remove kludgy formatting designed to avoid line wrap.
4145 * utils.c (wrap_here): If the line is already full (because
4146 we had printed a long indent or long wrapped string), do an
4147 immediate newline-and-indent.
4149 * m68k-pinsn.c (print_insn_arg): Bugfix from
4150 ntmtv!thompson@ames.arc.nasa.gov (Mike Thompson): 'bkpt #0'
4151 instruction is incorrectly disassembled as bkpt #8.
4153 * dbxread.c (end_psymtab): Bugfix from Peter Schauer
4154 <pesrem@regent.e-technik.tu-muenchen.de>: If you want to set a
4155 breakpoint in a *.y file gdb will say Reading in symbols for *.y...
4156 and then will dump core (sometimes). I traced it back to an
4157 uninitialized symfile_name in psymtab_to_symtab.
4158 (const_vol_complaint): Add quotes to message.
4159 (define_symbol): Only believe line number if gcc_compiled.
4160 Avoid allocating symbol if we will not return it.
4162 Add target strata support so that newly established targets go
4163 into their right place in the target stack (e.g. a new exec file
4164 doesn't wipe out the ability to access the running process).
4166 * target.h, core.c, exec.c, inftarg.c, remote-eb.c,
4167 remote-nindy.c, remote-vx.c, remote.c, target.c: Add to_stratum
4168 and initialize it properly in all the targets.
4170 * target.h: Document strata. Change return type of push_target.
4172 * target.c (nomemory): new function for dummy memory access.
4173 (tcomplain): Rename complain, now also used in symfile.c.
4174 (push_target): Push targets within strata. New return value shows
4175 whether new target is on top of stack or not. Always keep dummy
4177 (target_files_info): Ignore dummy target.
4179 * core.c (core_open): Warn user, and skip accessing file, if the
4180 core target is not the topmost target in the stack.
4181 * remote-nindy.c (nindy_create_inferior): Avoid unpush_target, now
4184 * remote-vx.c: Remove vx_prepare_to_store from vxworks memory
4185 target_ops, it doesn't belong there since we have no regs there.
4186 Change name of target from machine => memory to clarify.
4188 Thu Feb 7 16:32:09 1991 John Gilmore (gnu at spiff.cygnus.com)
4190 * Freeze version 3.93 for release.
4192 * Makefile.dist: Handle vx-share and nindy-share subdirs
4193 properly when building gdb.tar.Z.
4195 * symtab.c: lint; add no_symtab_msg to consolidate the messages
4196 printed in various places, so I could change just one copy.
4198 * dbxread.c, coffread.c: Change references to bfd->iostream
4199 to cast to FILE *, now that BFD avoids needing types defined
4200 in other header files.
4202 Tue Feb 5 21:39:35 1991 John Gilmore (gnu at cygint.cygnus.com)
4204 * command.c, dbxread.c, expprint.c, infcmd.c, infptrace.c,
4205 infrun.c, printcmd.c, remote-nindy.c, source.c, sparc-tdep.c,
4206 sparc-xdep.c, symfile.h, symmisc.c, utils.c, valprint.c: Lint
4207 (actually gcc -Wall).
4209 * dbxread.c: Remove first_global_sym, last_global_sym, since
4210 they are never referenced.
4212 * defs.h (baud_rate): Declare.
4213 main.c: Define it, and add the -b option to set it.
4215 * gdb-int.texinfo: Add text on how to define a new host or target
4216 architecture, prompted by Per Bothner's questions about MIPS
4219 * gdb.texinfo: Document "complaints". Change doc of -q since
4220 gdb no longer prints the copyright and blurb if you specify a file
4221 name to be debugged (just like Emacs). Add doc for Nindy-specific
4222 command line flags for specifying target serial port and such.
4223 Update copyright to 1991.
4225 * gdbcore.h: Remove a large mass of now-useless crud, since BFD
4226 has taken over for us the job of ripping up executable files. The
4227 crud caused Per Bothner's port to not compile.
4229 * infrun.c (normal_stop): Avoid printing "Program exited
4230 normally" if we are in batch mode. This allows a GDB which
4231 executes a program on a target system, to behave like a Unix
4232 command (input from stdin, output to stdout, no extraneous
4235 * main.c (main): Allow additional machine-dependent command line
4236 options to be specified with the ADDITIONAL_OPTIONS,
4237 ADDITIONAL_OPTION_CASES, ADDITIONAL_OPTION_HELP, and
4238 ADDITIONAL_OPTION_HANDLER macros. Also allow machine-dependent
4239 processing to occur just before the main loop with
4240 BEFORE_MAIN_LOOP_HOOK.
4241 (main): If a "core file" argument is specified, and it is not a
4242 core file, try it as a process ID to attach.
4243 (symbol_completion_function): Attempt to cope with
4244 "show screen-" TAB, not very successfully. This needs more work,
4246 (batch_file): New function, returns whether we are reading
4247 commands from an interactive tty on stdin, or from somewhere else.
4248 Called by normal_stop since it doesn't get from_tty passed down
4249 to it like many commands do.
4251 * remote-nindy.c: Handle command line options for nindy
4253 (nindy_before_main_loop): Prompt user for tty name if they
4254 don't specify it before getting to the interactive command loop.
4256 * tm-i960.c: Add ADDITIONAL_OPTIONS, etc, to handle -O, -brk,
4257 and -r command line options. Also add hook before main loop
4258 to make it easy to specify a tty.
4260 * TODO: More things to do, one done.
4262 Mon Feb 4 23:57:39 1991 John Gilmore and Mike Tiemann (at cygint.cygnus.com)
4264 * dbxread.c: Make complaint() calls pass pointer, not struct.
4265 Add complaints about badly formatted C++ type information
4266 (const/volatile indicator, and parse errors resulting in
4267 error_type). Fix C++ virtual member fn comment.
4268 (read_struct_type): Avoid bumping pointer if we got a parse
4269 error; this prevents our walking beyond the end of a string.
4270 Terminate loop on null char as well as semicolon.
4271 (process_one_symbol): Fix the LBRAC fix so that it uses the
4272 last previous SLINE, FUN, or SO record's PC address. C++ debug
4273 symbols did not have SLINE records in a useful order compared
4274 to the LBRAC records.
4275 (define_symbol): Handle "catch" records.
4277 * symtab.c (check_stub_type): Added new complain
4278 `stub_noname_complain' and added a consistency check to
4279 keep the debugger from crashing when finishing from an
4280 exception frame. A real fix will be needed later.
4282 Sat Feb 2 10:43:05 1991 John Gilmore (gnu at cygint.cygnus.com)
4284 * infcmd.c (attach_command): Make global.
4286 * Makefile.dist (REMOTE_OBS): Make these compile by default,
4287 but make them easy to comment out. Perhaps later they should
4288 be enabled by what CPU you configure for? FIXME.
4289 (VERSION): Roll to 3.93.
4290 (pinsn.o): Remove rule for obsolete file.
4291 (dbxread.o,coffread.o,mipsread.o): Use ${srcdir} explicitly.
4293 Run down a problem that manifested by printing the wrong function
4294 name in stack traces of read_ofile_symtab. Turned out that the
4295 problem was the SunOS 4.1.1 (and previous) C compiler outputs
4296 the LBRAC symbol with an address in the *data* segment, which
4297 blew our binary search through the blocks.
4299 * dbxread.c: Use the complain() facility consistently to bitch
4300 about problems in the symbol file we are reading.
4301 (finish_block): Add code to check the nesting of the blocks;
4302 complain and Procrust them to fit if wrong.
4303 (make_blockvector): Check the order of the blocks, complain
4304 [but don't cope] if wrong.
4305 (process_one_symbol): ifndef SUN_FIXED_LBRAC_BUG, check LBRAC
4306 symbols to be sure their PC value is greater than the last SLINE
4307 (line number) symbol we've seen, complaining and adopting the
4308 SLINE PC value if wrong.
4310 * symfile.h (struct complaint, complaint_root, complain,
4311 clear_complaints): Add.
4312 * symfile.c (complain, complaint_root, clear_complaints): Add
4313 facility to deal with non-fatal complaints and to regularize their
4315 (symbol_file_add): Clear complaint counters to allow new complaints.
4316 (initialize_symfile): Add 'set complaints' and 'show complaints'.
4318 * dbxread.c (dbx_symfile_read): Remember the address and size
4319 of the string table for the main symbol file, so we won't read it
4321 (dbx_psymtab_to_symtab): Fix the check for main symbol file,
4322 to avoid reading the string table yet again. Lint.
4323 (throughout): Improve filtered output, including word wrap.
4324 (read_range_type): Improve Bothner's fix to handle other types too.
4326 * utils.c: Improve line wrap implementation. Handle unlimited
4327 width by making chars_per_line unsigned.
4328 (puts_filtered): New, easy, function.
4330 * defs.h (puts_filtered): add.
4332 * mipsread.c (compare_symbols, sort_symtab): Remove these fns,
4333 call the identical sort_symtab_syms() in symfile.c instead.
4335 * expread.y: Suggest the `file' command rather than `symbol-file'.
4337 * command.h (enum var_types): Add zinteger for seroable
4339 * command.c (do_setshow_command): Handle var_zinteger. Restructure
4340 nested if's into a switch.
4342 * breakpoint.c (bpstat_print): If bpstat "print" flag is not set,
4343 we did not stop because of a breakpoint (it must have been for
4344 some other reason, like a "stepi"), so don't print anything.
4346 * symtab.c: Include <sys/types.h> all the time. Now that BFD
4347 doesn't include <sys/types.h>, old SunOS's require it for
4350 Sat Feb 2 10:39:15 1991 Per Bothner (bothner@cs.wisc.edu)
4352 A test port of gdb-3.92.6 to the Sony NEWS.
4355 Don't normally link in remote- or vx stuff.
4356 Some of it doesn't compile, and it wastes space for 99% of the users.
4357 Remove reference to no-longer-used HAVE_VPRINTF.
4358 Fixed BFD_DEP typo to BFD_DIR.
4360 Fix cast in arg to bfd_h_getlong.
4361 Make char *prefix be const.
4362 Fix how certain range types are mapped into builtin unsigned int types.
4364 Remove 2 #includes. They cause errors (on Sony, at least),
4365 and aren't needed (they wern't in earlier versions).
4367 print_address_symbolic should never demangle labels
4368 (since it prints *assembler-level* labels).
4370 [This was superseded by the change to printcmd below.]
4373 Add some "volatile" return types to avoid warnings.
4374 If MISSING_VPRINTF add vprintf function and not just macro
4375 (since vprintf is used in printcmd.c).
4377 Unless __GNUC__, use obstack_grow instead of obstack_ptr_grow.
4378 (The latter isn't grokked by some PCC-based compilers.)
4380 [This change is in abeyance, we prefer to fix obstack_ptr_grow.]
4382 Make chunk size of dont_print_obstack 32*4 instead of default 4096.
4383 * nindy-share/coffstrip.c
4384 Added some forward declarations (otherwise, gcc complains
4385 about implicit extern redefined as static).
4387 Sun Jan 20 02:38:19 1991 John Gilmore (gnu at cygint.cygnus.com)
4389 Changes inspired by Per Bothner:
4390 * printcmd.c (print_address_symbolic): Take additional parameter
4391 specifying whether to demangle.
4392 (print_address): Pass in asm_demangle to control demangling.
4393 (print_address_demangle): New fn, takes explicit arg to control
4395 * utils.c: Add new vars demangle and asm_demangle, and let them
4397 (fputs_demangled): If !demangle, just print the argument.
4398 (fprint_symbol): If !demangle, just print raw symbol.
4399 * valprint.c (val_print): Call print_address_demangle rather than
4400 print_address, to cause demangling to depend on the global
4401 rather than assembler-level demangling setting.
4402 * WHATS.NEW, gdb.texinfo: Document.
4404 * main.c (show_command): Show all settings if no arg.
4405 (initialize_main): Make "info set" the same as naked "show".
4406 * command.c (cmd_show_list): Handle prefix commands in the
4407 list, and print the name of the setting as well as its English
4408 description and value.
4410 Allow gdb functions to specify where a line should wrap if it
4411 exceeds the size of a terminal line. Use it to make the output
4413 * utils.c (set_screen_width_command): New fn, mallocs a buffer
4414 of the right size when screen width changes.
4415 (set_screensize_command, screensize_info): Remove #if 0'd fns.
4416 (wrap_here): New fn, indicates a point in the output where we
4417 should wrap the line rather than just letting it overflow at a
4419 (fputs_filtered): Implement wrapping.
4420 (n_spaces): New fn, returns a pointer to N spaces.
4421 (print_spaces_filtered): Use n_spaces.
4422 * defs.h (n_spaces): Declare.
4423 * stack.c (print_frame_info): Wrap with 4-space indent after
4424 fn name and before filename and line number.
4425 * printcmd.c (print_frame_args): Wrap with 4-space indent
4426 before each argument name is printed.
4427 * valprint.c (value_print): Wrap with no indentation before
4429 (val_print_fields): Wrap with indentation relative to nesting
4430 level before each field name.
4431 (val_print): Wrap with nesting indentation before array elements.
4432 * command.c (do_setshow_command): Avoid extra newlines,
4433 wrap with 4-space indent around values printed, end with period.
4434 * WHATS.NEW, gdb.texinfo, gdb-int.texinfo: Document.
4436 * breakpoint.c (breakpoint_1): Implement addressprint for
4437 "info breakpoints" display. Change file name and line number
4438 format to " at file:nnn" rather than " (file line nnn)".
4439 * gdb.texinfo: Document.
4442 Fri Jan 18 07:21:25 1991 John Gilmore (gnu at cygint.cygnus.com)
4444 Frozen for gdb-3.92.6 release.
4446 README, WHATS.NEW: Update for 3.92.6 release.
4448 tconfig/{altos, i386v, i386v32, m88k, umax}: Eliminate
4449 coffread.o from configs since it is now built by default.
4450 tconfig/{3b1, altosgas, arm, convex, hp300bsd, hp300hpux,
4451 i386v-g, i386v32-g, isi, merlin, news, news1000, np1, pn,
4452 pyramid, symmetry, vax, vxworks68}: Eliminate dbxread.o
4453 from configs since it is now built by default.
4455 Makefile.dist: Update for release 3.92.6. Handle files that
4456 have been moved to ../include, ../getopt, or ../bfd. Add
4457 saber.suppress and tests directory. Add config.status to
4458 the release (it will say "none").
4460 coredep.c: Minor formatting fixes.
4462 These changes were made in early December but only checked in now:
4463 * nindy-share/Onindy.c, nindy-share/coffstrip.c,
4464 nindy-share/nindy.c: lint
4465 * nindy-share/nindy.c (ninStopWhy): Don't byteswap the
4466 register values coming back from the target; we store values
4467 in target byte order everywhere.
4469 Wed Jan 16 19:01:37 1991 John Gilmore (gnu at cygint.cygnus.com)
4471 * am29k-opcode.h, am29k-pinsn.c: Add 29050 opcodes.
4473 * valprint.c (cplus_val_print, val_print_fields): New functions,
4474 which print C++ objects. They conspire to avoid printing a
4475 virtual base class more than once, following all the twists and
4476 turns of C++ virtual base rules.
4477 (val_print): Call the above rather than do it by hand.
4479 * symfile.c (symbol_file_add): Only reset symfile_mtime for main
4480 symbol file, not for added files like shared libs. This really
4481 needs to be generalized to a timestamp per file.
4483 * core.c (cleanup_core): Avoid coredump if no core file.
4485 * config.gdb: Accept -host or -target in place of +host or
4488 * coffread.c (find_linenos): Avoid desupported BFD interface
4489 to line numbers. We still read them manually rather than using
4490 BFD's "generic" features.
4492 * gdbrc.tex, threecol.tex: Add GDB reference card and its
4494 Makefile.dist: Add refcard to OTHERS list for creating tar files.
4496 * Makefile.dist: Eliminate use of $< in explicit targets.
4498 * readline/Makefile: Use $< rather than $*.c, which does not
4499 include the VPATH in GNU Make.
4501 * tconfig/i960-bout, tconfig/i960-coff: These are identical
4502 copies of tconfig/i960, added for global configuration
4503 compatability. All i960 versions can read both coff and b.out.
4505 * tm-88k.h: Fix multiline macro that lacked \'s. Remove
4506 COFF_FORMAT and COFF_CHECK_X_ZEROES since these are now handled
4509 * TODO: Think of more things to do.
4511 Wed Jan 2 19:09:29 1991 John Gilmore (gnu at spiff.cygnus.com)
4513 tconfig/{am29k,i960,sun2*,sun3*,sun4*}: Eliminate config
4514 of sdb versus dbx debug symbols. Add kludge for 68881 80-bit to
4515 64-bit float conversion.
4517 tconfig/sun4, tconfig/sun3, xconfig/sun4, xconfig/sun3: Make
4518 equivalent to sun?os4 so global config works.
4520 Wed Jan 2 18:20:51 1991 John Gilmore (gnu at spiff.cygnus.com)
4522 Fix from Eberhard Mattes <mattes@azu.informatik.uni-stuttgart.de>
4524 * main.c: Only declare linesize once; declare pagesize not at
4525 all, since it is never used.
4526 (main): Clear newly allocated line before it is used.
4528 Fri Dec 28 00:13:42 1990 John Gilmore (gnu at cygint)
4530 Further stabilization for the Intel 960.
4532 * Makefile.dist: Parameterize the location of the "include"
4533 and "bfd" directories, as well as "getopt". Add symfile.c.
4534 Link in both dbxread and coffread. Fix up "make depend" to
4535 rewack the locations of include, bfd, and getopt in its output.
4537 * README: Document moving include files, improve some of
4540 * coffread.c: Move common code out to symfile.c. Change
4541 symbol_file_command style interface to use new *_symfile_init
4542 and *_symfile_read interface under BFD. Use BFD internal
4543 info to locate line table, symbols, etc.
4545 * core.c (core_fetch_registers): Rename to get_core_registers
4546 to avoid confusion with fetch_core_registers.
4547 (register_addr): Move to coredep.c, which is already machine
4548 dependent. This leaves core.c pretty clean of dependencies.
4550 * coredep.c (register_addr): Accept this routine from core.c.
4552 * dbxread.c: Move common code (with coffread.c, etc) into new
4553 symfile.c. Each psymtab now contains a pointer to the
4554 format-dependent function that knows how to read it in. Make
4556 (dbx_psymtab_to_symtab): Renamed from psymtab_to_symtab_2.
4557 (process_one_symbol): Add code to complain about a "compiler bug
4558 we muzzle here", if we actually see it.
4560 * eval.c (evaluate_subexp): Insert missing "break" statements
4561 in code that determines whether a variable is an lvalue in
4562 memory, register, or whatever. I detected this via a compiler
4563 bug in which it *almost* mashed out the whole switch statement.
4565 * gdb-int.texinfo: Add minor sections on configuring gdb for
4566 release, and about the README file.
4568 * infcmd.c (registers_info): Fix formatting somewhat. Still
4569 not as pretty as before, but it handles byte swapping.
4571 * remote-nindy.c: If data cache routines are interrupted while
4572 waiting for the remote end, be sure that any uninitialized cache
4573 blocks are on the free list, not on the valid list!
4575 * symfile.h: Flesh out this header file with all the various
4576 routines and variables that have been merged in from dbxread.c
4577 coffread.c, and symtab.c to symfile.c.
4579 * symfile.c: New file, containing code common to dbxread.c,
4580 coffread.c, and some code from symtab.c. All generic code for
4581 reading symbol files should be in here now.
4582 (unrecord_misc_function): Remove unused function.
4584 * symtab.h: Remove file-reading things to symfile.h.
4586 * symtab.c: Remove file-reading things to symfile.c.
4588 * tm-i960.h: Fix FRAME_CHAIN types; define PRINT_RANDOM_SIGNAL
4589 to decode i960 fault types.
4591 * target.h, remote.c, remote-eb.c, remote-vx.c, remote-nindy.c,
4592 target.c: Change type of the "resume" function from int to void,
4593 since its result was never used.
4595 Sat Dec 22 02:51:40 1990 John Gilmore (gnu at cygint)
4597 * main.c: Replace "stupid" with "caution"; you now "set caution
4600 * printcmd.c (print_scalar_formatted): Fix typo in 'g' format
4602 * infcmd.c (do_registers_info): Call val_print to deal with the
4603 byte order of the registers being printed. FIXME, this makes
4604 the formatting of the output uglier.
4606 * infcmd.c (wait_for_inferior): If PRINT_RANDOM_SIGNAL is
4607 defined, call it for signals the debugger doesn't itself use.
4608 The i960 uses this for more detailed fault information.
4610 * remote.c (remote_open): If arg is null, print help rather than
4613 * sparc-xdep.c (register_valid): Avoid declaring size, since
4614 various modules will think of various sizes depending on the
4615 architecture of their tm-file. FIXME, we need protection against
4616 actually entering one of those modules, which would clobber
4617 storage if not for the target architecture compiled into gdb.
4619 * stack.c (up_command, down_command): Always print the frame
4621 (up_silently_command, down_silently_command): New commands
4624 * i960-pinsn.c (reg), i960-tdep.c: Lint.
4626 * i960-tdep.c (i960_frame_chain_valid): Lookup_symbol now takes
4627 more parameters than it used to.
4629 * findvar.c (registers): Increase slop to 256 bytes, which should
4630 protect us against even most RISC machines with large register
4632 (locate_var_value): Move declaration inside related ifdef.
4634 * remote-nindy.c (): Use TIOCSETN rather than TIOCSETP
4635 throughout, to avoid throwing away buffered input from the board.
4636 (nindy_wait): Supply_register takes addr_of_value, not value.
4637 (i960_print_fault): Renamed from i80960_fault.
4638 (nindy_fetch_registers): Avoid have_regs stuff, just get them.
4639 (nindy_store_registers): Avoid regs_changed stuff, just stuff
4641 (nindy_create_inferior): Don't bother to write PC_REGNUM since
4642 we can set the PC in the call to proceed(). Unpush nindy_ops
4643 before pushing it on top, to avoid message to user. Eliminate
4644 commentary from Unix machines that just misleads here.
4645 (reset_command): Fix error message to suggest target command.
4647 Wed Dec 19 11:03:56 1990 John Gilmore (gnu at cygint)
4649 Release 3.92.5 as frozen.
4651 Stabilize the merged release...with help from lint, Saber C,
4654 Everywhere: Add include files needed to declare return types
4655 of functions called.
4657 * gdb.texinfo: Roland Pesch is documenting gdb, glory be!
4659 * breakpoint.h: Add undeclared breakpoint functions, and some
4660 functions for display handling since I couldn't think of a better
4663 * breakpoint.c (insert_breakpoints): Make code for disabling
4664 shared library bkpts more likely to work. It's used when we
4665 rerun a program and stop before the shared library has been
4667 (breakpoint_cond_eval, bpstat_stop_status): Pass arg as int,
4668 cast from pointer, so it squeezes through catch_errors.
4669 (bpstat_stop_status): Fix logic broken some time ago. We now
4670 always create a bpstat if the stop address matches a breakpoint,
4671 even if we don't stop there -- just like the old code used to do
4672 before I got my fingers into it (sigh).
4673 (breakpoint_1): Print "ignore count" after "stop only if"
4674 condition, since that's how it actually works.
4675 (mention): Handle watchpoints as well as breakpoints.
4676 (watch_command): use set_raw_breakpoint and mention to do most
4677 of the work (and initialize all the fields!). Only pass one
4678 arg to parse_c_expression, since that's all it takes.
4680 * command.c (not_just_help_class_command): Rename arg to args
4681 since we ignore "unused argument" warnings on vars named "args".
4682 inflow.c (child_terminal_info): ditto.
4683 infptrace.c (kill_inferior): ditto
4684 main.c (catch_errors, version_info, quit_command, pwd_command,
4685 source_command, dump_me_command, editing_info,
4686 set_history_size_command, set_history, show_history,
4688 stack.c (locals_info): ditto
4689 target.c (target_files_info): ditto
4690 valprint.c (set_input_radix, set_output_radix): ditto
4692 * core.c: Remove old variables for handling core and exec file
4693 sections (data_start, data_end, stack_start, stack_end,
4694 reg_stack_start, reg_stack_end, reg_stack_offset, text_start,
4695 text_end, exec_data_start, exec_data_end, text_offset,
4696 exec_data_offset, data_offset, stack_offset). They're
4697 superseded the more general build_section_table and
4699 (get_exec_file): Mention the `file' command.
4700 (read_memory_check): Rename to memory_error, and only call it
4701 in the case of an actual error.
4702 (read_memory, write_memory): call memory_error.
4703 (core_fetch_registers): Register section name is ".reg".
4705 coredep.c: Remove a bunch of crud now that all this file does
4706 is pull the registers out of a core file.
4707 (fetch_core_registers): Rewrite to actually work, I hope.
4709 dbxread.c: Use a.out.gnu.h, not system a.out, now.
4710 Replace index() with strchr(). Remove all the pre-BFD macro
4711 definitions for accessing the symbol file.
4712 (struct dbx_symfile_info): Encapsulate the information that
4713 dbx_symfile_init needs to pass to dbx_symfile_read in this
4716 (dbx_new_init, dbx_symfile_init, dbx_symfile_read,
4717 dbx_symfile_discard): Rearrange symbol file reading to divide
4718 the format-specific part from the format-independent part,
4719 leaving the format-independent part such as file name expansion
4720 and opening in symtab.c. This replaces
4721 partial_symbol_file_open and partial_symbol_file_read.
4722 Symbol_file_read, add_file, add_file_target_command,
4723 add_file_addr_command move to symtab.c. Pass an explicit
4724 "mainline" flag for when reading the main symbol table, rather
4725 than relying on the offset address to be zero or nonzero.
4727 (dbx_symfile_read): Don't allow void *'s to be printed as
4729 (SWAP_SYMBOL): Use bfd routines to byte-swap the symbols.
4730 (ADD_PSYMBOL_TO_LIST): Make the "function call rather than
4731 macro" debug version really work.
4732 (read_dbx_symtab): Remove unref'd parameter inclink.
4733 Avoid swapping N_SLINE symbols, for speed.
4734 Merge N_TEXT!N_EXT case with the other external symbol
4735 definitions' case. Add comments.
4736 (start_psymtab): Allocate the symfile name in the psymtab on
4737 the psymbol_obstack, rather than using the caller's storage.
4738 (end_psymtab): Only allocate a dependencies list if there are
4740 (psymtab_to_symtab_2): Use BFD when reopening file to read
4741 its symbols for real.
4742 (read_struct_type): Add FIXME comments where it needs work
4744 (read_huge_number): Add FIXME about overflows.
4745 (read_range_type): Add FIXME about comparing a long to 1<<32.
4747 * coffread.c: Minor changes to move things closer to the new
4748 regime with symtab.c and dbxread.c Major work is still needed
4751 * exec.c (exec_file_command): Remove old variables (see core.c
4753 (xfer_memory): If memory transfer is right at the end of a
4754 section, don't lose.
4756 * findvar.c (get_saved_register): If value is in a real
4757 register, LVAL is lval_register, not lval_memory.
4759 frame.h: Declare print_sel_frame and record_selected_frame.
4761 gdb-int.texinfo: New file, for GDB internals documentation.
4762 Very simple, unformatted doc of cleanups is there for now.
4764 gdbcore.h: Remove obsolete variables that described a.out
4765 section addresses and offsets. (See core.c above.)
4766 Declare fetch_core_registers and registers_fetched.
4768 getopt.c: Declare char *alloca(); even on SPARC.
4770 infcmd.c (run_command): Call target_kill rather than
4772 (step_command, next_command, stepi_command, nexti_command):
4773 Declare from_tty parameter even though we don't use it.
4774 (run_stack_dummy): argument BUFFER is a char array, not
4775 a pointer to REGISTER_TYPE.
4776 (finish_command): using_struct_return needed a value *,
4777 not a struct symbol *.
4779 * infptrace.c (child_xfer_memory): To avoid dependency on
4780 where sections are in memory, try PT_WRITE_D and if that fails,
4781 try PT_WRITE_I. Most Unixes don't care which you use.
4783 * infrun.c (step_resume_break_shadow): Change to array to
4784 match other breakpoint shadow storage.
4785 (clear_proceed_status): Pass address of bpstat to
4786 bpstat_clear, not the bpstat itself.
4787 (child_create_inferior): FIXME comment about if the child
4789 (start_inferior): Remove old function.
4790 (child_open): Use target_kill rather than kill_inferior.
4791 (wait_for_inferior): Ditto.
4792 (insert_step_breakpoint, remote_step_breakpoint): Use
4793 new step_resume_break_shadow.
4795 * inftarg.c (child_wait): If all child processes die,
4796 pretend that the one being waited for exited with signal 42.
4798 * main.c (command_line_input): When scanning for comments,
4799 don't coredump on unclosed quotes.
4800 (quit_command): Use target_kill rther than kill_inferior.
4801 (_initialize_main): Rename class_user from "user" to
4804 * printcmd.c (print_command_1): Initialize "fmt" if no format
4805 is specified by the user.
4806 (print_frame_args): Only add to args_printed if we are
4807 actually fetching args from the stack (avoiding undefined
4809 (_initialize_printcmd): Remove bogus \{ from string.
4811 * remote-eb.c (eb_open): Avoid coredump on no argument.
4813 * remote-nindy.c: Bring out of Intel environment into new
4814 target environment. Remove all conditional compilation on
4815 I80960. Massive hacking throughout.
4816 (nindy_xfer_inferior_memory): New routine stolen from
4818 (nindy_create_inferior): New routine pieced together, probably
4819 not quite working yet.
4820 (nindy_ops): New target_ops struct for nindy.
4822 * remote-vx.c: Use write_memory rather than target_write_memory
4823 to get error checking.
4824 (vx_add_file_command, vx_open): Use symbol_file_add rather than
4826 (vx_create_inferior): Use target_terminal_ours...
4828 * signame.c (_initialize_signame): Always initialize, since
4829 we need the table for things other than psignal.
4831 * solib.c (solib_add): Use symbol_file_add, not add_file.
4832 (solib_address): Return boolean result rather than struct
4833 pointer which nobody else knows the type of.
4835 * sparc-tdep.c, valops.c: Use write_memory rather than
4836 target_write_memory, to get error checking.
4838 * stack.c (locals_info, catch_info, args_info,
4839 get_selected_block, frame_command, up_command): Use
4840 target_has_stack, rather than have_inferior_p or
4843 * sun3-xdep.c (fetch_core_registers): Rewrite for new BFD regime.
4845 * symfile.h: New file, defining the interface between the
4846 generic and object-file-specific symbol reading code.
4848 * symtab.c: Move generic symbol-reading interface to symtab.c,
4849 from dbxread.c, coffread.c, mipsread.c, etc. Add symtab_fns
4850 table to map BFD targets to symbol-reading modules in GDB.
4851 Change index to strchr.
4852 (lookup_struct_elt_type): Use error() rather than hand-made
4853 simulations thereof.
4854 (lookup_partial_symbol): Speedup slightly when length == 0.
4855 (symbol_file_add): New function.
4856 (symbol_file_command): Call it.
4857 (symfile_open, symfile_init): New function.
4858 (add_file_target_command, add_file_addr_command): moved from
4861 * target.c (target_command): use target_kill.
4863 * target.h (target_files_info): Don't declare, never called
4866 * tm-sun2.h, tm-sun3.h (STACK_END_ADDR): Use system include
4867 files to determine stack end address.
4869 * valarith.c (value_x_binop, value_x_unop): Change error message
4870 to be more useful. Pass proper argument to value_struct_elt.
4872 * valops.c (value_assign): FIXME comment that long long
4873 bitfields will break here.
4875 * Makefile.dist: Add symfile.h, remote-nindy.c, remote-eb.c.
4876 Update `make saber_gdb' to work better.
4878 * TODO: A woman's work is never done.
4880 * cplus-dem.c, environ.c, inferior.h, infrun.c, inftarg.c,
4881 main.c, obstack.c, printcmd.c, remote-eb.c, remote-nindy.c,
4882 remote-vx.c, remote.c, solib.c, source.c, sparc-pinsn.c,
4883 sparc-tdep.c, sparc-xdep.c, symmisc.c, symtab.c, symtab.h
4884 target.c, terminal.h, tm-sparc.h, tm-sunos.h, utils.c,
4885 valops.c, valprint.c, exec.c: Lint.
4888 Wed Dec 12 23:44:15 1990 John Gilmore (gnu at cygnus.com)
4890 Continuing Intel 960 port merge of GDB.
4892 * Makefile.dist: Merge i960 "nindy-share" files. Rename
4893 malloc.h to gmalloc.h to avoid name conflicts in /usr/include.
4894 Don't ship gdb.dvi in tar file. Link gdb with init.o, not init.c.
4895 Wack over "make depend" so it handles files in subdirectories
4896 vx-share, nindy-share, bfd, and in the current directory.
4898 * blockframe.c (get_prev_frame_info): Remove fatal error
4899 if stack not defined.
4901 * core.c (core_open, core_detach): New functions that handle
4902 the old "core-file" command as "target core" and "detach" instead.
4903 (core_file_command): Call them.
4904 (core_xfer_memory): Use common routine xfer_memory.
4906 * dbxread.c: Include a.out.gnu.h, not system a.out.h.
4907 dbxread now uses bfd for everything but symbol reading itself.
4908 BFD internals are used to drag out the relevant file offsets.
4909 (partial_symbol_file_open): Change args all around for BFD.
4911 * symtab.c: Rename "value" to "val" everywhere, so we can
4913 (symbol_file_command): New command, moved from dbxread.c
4914 and coffread.c. It uses BFD to read the file, then vectors
4915 based on its type, to dbx or coff symbol readers.
4916 * symtab.h: Extern a few vars for symbol_file_command.
4918 * target.h: Breakpoint takes a char * save area, not a char **.
4920 * valprint.c (val_print): When unpacking bitfields, offset
4921 the address in gdb of the value, if it is declared with a shorter
4922 type. Remove the last "runtime kludge test" of host byte order.
4924 * utils.c: Remove old my_bfd_read routine.
4926 * stack.c (frame_info): Use target_has_stack. Print program counter
4927 register's actual name rather than "pc", since it's called the
4928 "ip" (instruction pointer) on the i960 (sigh).
4930 * target.c (target_command): Add command for selecting a target
4931 type and calling its open routine. This is used for initiating
4932 communication with a particular target, in a generic way.
4934 * tm-i960.h: Update for modern gdb. Remove semicolons from
4935 various macros. Handle reading struct return convention, and
4936 error-out attempts to return structs with the "return" command.
4937 Be sure gdb doesn't think we know how to call functions in the
4940 * i960-tdep.c: Rename FRAME_CHAIN_VALID and FRAME_FIND_SAVED_REGS
4941 to i960_xxx in lower case.
4942 (arg_address): Circumvent errors due to LOC_ARG_BLOCK
4943 not being defined yet.
4945 * remote.c (remote_open): Call start_remote to initialize
4946 wait_for_inferior during open.
4947 (remote_xfer_inferior_memory): Return length written rather
4950 * remote-vx.c (target_command -> vx_open): Use new generic
4952 * remote-eb.c, inftarg.c, exec.c: ditto.
4954 * infrun.c: Fix comments.
4955 (attach_program -> child_open): Use new generic target command.
4956 (wait_for_inferior): Clear saved register values before target_wait,
4957 so target_wait can set some of them if convenient.
4959 * infptrace.c (fetch_inferior_registers, store_inferior_registers):
4960 Return success indicator, not void.
4961 (child_xfer_memory): Avoid fetching initial word if we'll
4962 overwrite it anyway.
4964 * infcmd.c (attach_command): Use new generic target open routine.
4965 (_initialize_infcmd): Update doc on attach and detach commands.
4966 (do_registers_info): Merge in a byte-order problem as a FIXME
4969 * findvar.c (find_saved_register): Avoid problem in current frame.
4970 (read_relative_register): Ditto.
4971 (write_register): Convert byte order on the way out.
4973 * exec.c (file_command): Add.
4974 (add_to_section_table, exec_command): Use new bfd_map_over_sections.
4975 (xfer_memory): Common function between core_xfer_memory and
4977 (exec_xfer_memory): Use it.
4979 * pn-opcode.h: Document that a "PN" is a Gould PowerNode.
4981 * breakpoint.c, breakpoint.h, symtab.h, value.h, frame.h, utils.c,
4982 valops.c, stack.c, target.c, sparc-xdep.c, source.c, printcmd.c,
4983 infcmd.c, i960-pinsn.c, eval.c, defs.h: lint and gcc -Wall.
4985 Sun Dec 2 16:45:06 1990 John Gilmore (gnu at cygnus.com)
4987 Merge Intel 960 port of gdb, continuing...
4989 * dbxread.c (partial_symbol_file_open, partial_symbol_file_read,
4990 symbol_file_command): Pass from_tty arg to hush 'em up.
4992 * coffread.c (symbol_file_command): Avoid output if from_tty != 1.
4993 Add magic numbers for 960 COFF format.
4995 Fri Nov 30 09:18:20 1990 John Gilmore (gnu at cygnus.com)
4997 Merge Intel 960 port of gdb, from Intel "1.2" release.
4999 CHANGE_LOG entries from their port, which was based on
5002 Thu Sep 6 11:02:22 PDT 1990
5003 Remove temp file if download is interrupted.
5005 Wed Aug 1 09:08:33 PDT 1990
5006 Now uses binary protocol to talk to NINDY.
5007 Old hex protocol (NINDY 2.13 and older) supported with -O switch.
5008 Times out after 5 seconds when trying to talk to NINDY.
5010 Tue May 29 12:54:49 PDT 1990
5011 Added variable baud rate (-b switch).
5012 Source code reorganization.
5014 Thu Apr 26 11:09:55 PDT 1990
5015 More cleanup of batch mode; specifically, execute "-s", "-e", and
5016 "-se" switches as soon as they are encountered on the invocation line.
5018 Fri Apr 20 13:47:15 PDT 1990
5021 Thu Apr 19 09:54:28 PDT 1990
5022 Add 'reset' command.
5024 Wed Apr 18 09:48:07 PDT 1990
5025 After opening remote tty, wait for 1 second to go by without input
5026 from it before trying to talk to NINDY (fixes problems with the
5027 Heurikon HK80/V960E).
5029 Mon Apr 4 16:33:05 PDT 1990
5030 Some output was not being suppressed in 'batch' mode.
5032 Thu Mar 22 15:31:11 PST 1990
5033 Ask user if old symbol table should be deleted when new file is
5036 Allow user to run a program downloaded before gdb960 was brought up.
5038 Correct "exec-file" help message for i80960 context.
5040 Correct bug in calculating user space address: could occasionally
5041 corrupt user program.
5043 Make sure to zero low-order bits in rip's because of bug in 960CA
5044 A-step part: could cause operation faults when "next"ing across
5047 Correct bug that made it impossible to get source line numbers for
5048 code loaded at addresses higher than 0x7fffffff.
5050 Wed Jan 10 12:43:22 PST 1990
5051 Open remote tty for exclusive use.
5053 Fri Jan 5 12:14:42 PST 1990
5054 Correct disassembly (CA manual was right after all):
5055 opcode for sysctl is 0x659
5057 Mon Oct 23 12:03:04 PDT 1989
5058 Use G960BASE and G960BIN environment variables to find 'sx' utility.
5060 Mon Oct 16 14:15:09 PDT 1989
5061 "sfr0"-"sfr31" should have been named "sf0"-"sf31"
5063 Mon Oct 2 15:56:31 PDT 1989
5065 Added 960CA disassembly support.
5067 To simplify maintenance:
5068 - eliminated use of symblic links on pinsn.c: use i960-pinsn.c
5070 - eliminated opcode.h: incorporates tables into i960-pinsn.c
5071 - moved 960-specific routines from i960-pinsn.c to i960-md.c
5072 - made disassembly interface identical to that in gdmp960.
5076 Wed Nov 28 21:32:48 1990 John Gilmore (gnu at cygint)
5078 * target.h: Allow targets to stack. Add target_has_memory,
5079 _registers, etc. Restructure memory access and "info files"
5080 to walk the target stack.
5081 * exec.c, core.c, inftarg.c, remote.c, remote-vx.c, remote-eb.c,
5082 target.c: Change tables to match target.h.
5083 * inflow.c (child_mourn_inferior): pop child_ops.
5084 (generic_mourn_inferior): Use new has_stack flag.
5085 * infptrace.c (child_xfer_memory): New memory regime.
5086 * inftarg.c (child_files_info): New "info files" regime.
5087 * remote-eb.c: New memory regime, new info files.
5088 * remote-vx.c: New memory regime, new info files. Now use
5089 separate targets for VxWorks attachment to machine, and
5090 actually running a process under VxWorks, since one has
5091 stack & execution & regs and the other doesn't.
5092 * remote.c: New memory regime, new info files.
5093 * sparc-xdep.c (fetch_core-registers): New memory regime.
5094 * target.c: New routines and support for stacked targets,
5095 new memory regime, new info files regime.
5098 Generalize section handling for an arbitrary number of sections,
5099 including use of the new BFD (binary file) library.
5100 * gdbcore.h: Add struct section_table.
5101 * exec.c (build_section_table): Iterate all sections and
5102 record what gdb needs to know about them.
5103 (exec_command): Use it.
5104 (exec_xfer_memory): Use the table.
5105 (exec_files_info): Print the table.
5106 * core.c (core_file_command, core_xfer_memory, core_files_info):
5108 * source.c (find_source_lines): Use bfd_get_mtime.
5109 * dbxread.c: Quick changes to make it compile with new BFD.
5110 * utils.c (error): Avoid using bfd_error in generic routines.
5112 * core.c (core_fetch_registers): Get from the ".regs" section of
5114 * sparc-xdep.c (fetch_core_registers): Use the .regs info.
5116 * inferior.h (attach_flag): Export.
5117 * infcmd.c (run_command): use new target_create_inferior.
5118 * infrun.c (child_create_inferior): Don't return result.
5119 * Makefile.dist (VERSION): 3.91.4.
5121 Fri Nov 23 28:15:38 1990 John Gilmore (gnu at cygint)
5123 * breakpoint.c (bpstat_num): Handle breakpoints which have
5124 since been deleted, such as temporary breakpoints.
5125 infcmd.c (program_info): ditto.
5127 * core.c (core_file_command): Display the frame where the core
5132 * remote-vx.c (target_command): Merge in target command from
5133 targ-vx.c. A few other cleanups.
5135 * TODO, Projects: Lots more stuff to do...
5137 Fri Nov 23 18:15:38 1990 John Gilmore (gnu at cygint)
5139 Massive changes to wall off the remote-debugging interface
5140 behind a function vector. The port to handle VxWorks targets
5141 is also part of this.
5143 All files: Replace references to renamed functions,
5144 remove references to remote_debugging, remove references to
5145 have_include_file, have_core_file in favor of target_has_stack,
5146 target_has_memory, etc.
5148 * Modularize the breakpoint interface.
5149 breakpoint.h (BREAKPOINT_MAX): New define sets max length of
5150 a breakpoint instruction.
5151 breakpoint.c: struct breakpoint's shadow_contents now sized as
5153 (insert_breakpoints): Vector to target to install breakpoints.
5154 (remove_breakpoints): Vector to target here too.
5155 Remove REMOTE_SA_SPARC kludges and other remote_debugging.
5156 sparc-tdep.c (single_step): Use new breakpoint interface for
5157 the single-step breakpoints.
5158 mem-break.c (memory_insert_breakpoint, memory_remove_breakpoint):
5159 New file, contains routines to insert and remove breakpoints by
5160 reading out the old contents and later replacing them. This is
5161 how ptrace breakpoints work, and many remote systems as well.
5163 * tm-vxworks68.h: New config file, overrides a few things for
5164 Wind River's preferences.
5166 * target.h: New file, for transfer vector used to talk to the
5167 inferior (child, attached, core, exec, remote, etc). All accesses
5168 to the thing being debugged should come through these vectors.
5169 target.c: New file, routines to handle transfer vector.
5170 (various files): Add transfer vectors XXX_ops for the various
5171 targets and pseudo-targets (core files, etc) we support.
5173 * breakpoint.c (bpstat_stop_status): Further explorations of
5174 watchpoints and why things don't work all the time.
5175 (bpstat_alloc): New fn to allocate a bpstat and chain it.
5177 * config.gdb: Only add "source ${srcdir}/.gdbinit" to
5178 the local gdbinit if it doesn't already have it.
5180 * core.c (core_ops): add and install.
5181 Allow core debugging without exec file.
5183 * dbxread.c (free_and_init_header_files): Merge two fns.
5184 (end_symtab): Free named symbol table when a new version comes in.
5185 (read_dbx_symtab): Relocate all kinds of symbols with base
5186 address. First step toward handling different text, data, bss
5188 (add_file_addr_command): Renamed add_file_command.
5189 (add_file_command): Vector to remote handler.
5190 Add "load" as an alias for "add-file" command.
5192 * defs.h: Allow "volatile" to be used in non-ANSI; use it for
5193 non-returning functions.
5195 * exec.c: Add exec_ops, and push it as a target when an exec
5198 * infcmd.c (run_command): Pass executable file name and arg list
5199 separately when starting an inferior. Permit "run" when no exec
5200 file is specified, for VxWorks.
5201 (detach_command): Move to child_detach in inftarg.c.
5203 * inftarg.c: New file. Unix-child-specific routines, and the
5204 child_ops structure.
5206 * inferior.h (registers): Export "registers" as the way for
5207 target dependent register handlers to find gdb's local copy of
5208 the registers. Rename "stop_after_attach" to "stop_soon_quietly"
5209 since it is now used by places that want wait_for_inferior to
5210 handle the grunge but want to see every trap from the inferior.
5212 * inflow.c (create_inferior): Pull out, and merge into infrun.c.
5213 Eliminate remote_debugging hooks in terminal handling.
5215 * infrun.c: Replace start_inferior with child_create_inferior.
5216 Move all the hair of Unix shells and ptrace idiosyncracies into
5217 child_create_inferior, so remote handlers don't have to deal.
5218 Remove running_in_shell. Rename stop_after_attach to
5219 stop_soon_quietly, and use it in a few other places where we want
5220 to just call wait_for_inferior and get control back on the first
5221 trap. trap_expected now never takes a value > 1.
5222 (init_wait_for_inferior): Initialize static vars when a new
5225 main.c (gdbinit): Add new hook for .gdbinit file name, let
5226 it be overridden by config files as GDBINIT_FILENAME.
5227 (DEFAULT_PROMPT): Add new hook for overriding (gdb) prompt.
5228 Both of these are used for VxWorks gdb.
5230 mcheck.c: rename include file "gmalloc.c" to avoid problems
5231 with system include file "malloc.c".
5233 param-no-tm.h: New include file, same as param.h but does not
5234 include the default "tm.h" file. This is used in files where
5235 the target is known, e.g. remote-eb.c or sparc-xdep.c.
5237 param.h: Now just a shell that includes tm.h and param-no-tm.h.
5239 remote-vx.c: New file, VxWorks remote debugging support. Uses
5240 RPC routines that are shared with the target system, in directory
5243 remote.c: Vectorize remote interface.
5245 source.c: Globalize source_path, and make an alias "l" for "list"
5246 since we now have the "load" command.
5248 sparc-xdep.c: Use new param-no-tm.h.
5250 symmisc.c (free_named_symtab): Add new function from Wind River.
5251 However, ifdef it out for now while we think about what it should
5254 tm-sun3.h, xm-sparc.h, xm-sun3.h, xm-symmetry.h: Move
5256 the xm- file, and change its name to CHILD_PREPARE_TO_STORE, since
5257 non-Unix-children handle this with their own code in the target
5260 Makefile.dist: Roll version to 3.92.3. Add vx-share stuff to
5261 source and target lists. Add vx-share to default list of include
5262 directories. Add new files to src and target lists: mem-break,
5263 target, inftarg, remote-eb, remote-vx, targ-vx. Be sure the
5264 ${srcdir} versions of munch and createtags are used.
5266 * valops.c (find_function_addr): Split out of call_function.
5267 (call_function_by_hand): Rename call_function; this function
5268 calls functions in the target by laboriously patching the target
5269 word-by-word with the right stack, args, regs, etc.
5272 Mon Nov 5 17:29:10 1990 John Gilmore (gnu at cygint)
5274 Handle AMD 29000 a bit better.
5276 * remote-eb.c (readchar): Mask received char log to make it readable.
5277 (remote_start): Pass arguments down to executing program.
5278 Make startaddr unsigned.
5279 infrun.c (start_inferior): Accept args, pass them to
5281 infcmd.c (run_command): Pass args down to start_inferior.
5283 * tconfig/am29k-aout, tconfig/am29k-coff: New files specifying
5284 the target object file format.
5285 tm-29k.h: Pay heed to COFF_ENCAPSULATE.
5287 * am29k-pinsn.c (print_insn): Print 0x on hex numbers in disassembly.
5288 am29k-tdep.c (examine_prologue): Better checking of function prefixes.
5290 Sun Oct 7 18:20:45 1990 John Gilmore (gnu at cygint)
5292 * Makefile.dist (VERSION): Roll version to 3.91.9 and freeze.
5293 * TODO: We did a few things, we have more to do though.
5295 * xm-sparc.h (CLEAR_DEFERRED_STORES): Define.
5296 * inflow.c (inferior_died): Clear deferred stores.
5298 * Debug problems with dummy frames and calls to the inferior.

5300 * sparc-tdep.c (do_restore_insn): Simplify.
5301 (sparc_frame_find_saved_regs): Simplify and fix what we find.
5302 (sparc_push_dummy_frame): Simplify and fix what we push.
5303 (sparc_pop_frame): Slightly more hair here, deciding whether
5304 we are restoring a saved PC or returning to a return address in %i7.
5305 * sparc-xdep.c (read_inferior_registers): Debug if valid reg is read.
5307 * utils.c (xmalloc, xrealloc): Return type depends on __STDC__.
5308 * symtab.h (xmalloc): ditto, for obstack_chunk_alloc.
5309 * obstack.h (chunkfun): ditto.
5310 * defs.h (xmalloc, xrealloc): ditto
5312 * utils.c (quit): Grab the terminal from the child if necessary.
5314 * inflow.c (term_status_command): Rename to term_info, change
5317 * sparc-pinsn.c (print_insn): Disassembly prefers real instructions.
5318 (is_delayed_branch): Speed up.
5319 * sparc-opcode.h: Add ALIAS bit to aliases. Fix up opcode tables.
5320 Still missing some float ops, and needs testing.
5322 * Support for input and output radixes other than base 10
5323 * defs.h (input_radix, output_radix): Declare.
5324 * expread.y (yyparse, parse_number): Handle changes of input
5325 radix, and ambiguous names-or-numbers in radixes >10.
5326 * printcmd.c (print_scalar_formatted): Print formatted hex
5327 numbers in varying column widths.
5328 * valprint.c (val_print): Use output_format to print scalar ints.
5329 (set_input_radix, set_output_radix, set_radix): Create.
5330 (set_output_radix): Set output_format from output_radix.
5331 (_initialize_valprint): add `set radix' but leave the others off.
5333 * main.c (execute_command): Let stupid questions be turned off.
5334 (_initialize_main): Handle "set stupidity", etc.
5336 * main.c, inflow.c, inferior.h, frame.h, command.c, defs.h,
5337 sparc-pinsn.c, sparc-xdep.c, value.h, valops.c, values.c: Lint.
5339 Tue Oct 2 11:20:02 1990 John Gilmore (gnu at cygint)
5341 * TODO, Makefile.dist, ChangeLog: Freeze for 3.91.8 release.
5342 bfd stuff is still screwed up, but with some manual work, it
5345 * breakpoint.c (bpstat_do_actions): Start over if a command
5346 proceeds the inferior, since the inferior will have stopped and
5347 will need to have its new stop-actions taken care of.
5349 * dbxread.c (read_struct_type): Expression gives Sun3 4.0.3
5350 compiler fits, simplify it.
5352 * gdb.texinfo (directory command): Doc new dir command.
5353 source.c (directory_command): "dir" now puts things on the front
5354 of the path, moves dups up front, and handles multiple names
5355 on the command line, inserting each one in order. It also
5356 blows away cached line and full_filename info.
5358 * stack.c (backtrace_command): Skip "more stack frames follow"
5361 * Change #ifndef HAVE_VPRINTF to #define MISSING_VPRINTF in
5362 xm-convex.h, xm-hp300bsd.h, xm-isi.h, xm-merlin.h, xm-news.h,
5363 xm-np1.h, xm-pn.h, xm-pyr.h, xm-symmetry.h, xm-umax.h, xm-vax.h.
5364 The only odd one was Gould NP1, which had defined vprintf to
5367 * Merge Ted Goldstein <tedg@Eng.sun.com>'s changes for epoch.
5368 printcmd.c (print_command_1): Pass 'inspect' flag down as a global
5369 variable, inspect_it.
5370 valprint.c (print_string, val_print): Use the global inspect_it
5371 to indicate whether to print in Epoch style or normal style.
5373 Mon Oct 1 23:55:26 1990 John Gilmore (gnu at cygint)
5375 * printcmd.c (call_command): add an alias for the "print" command
5376 which runs expressions and doesn't print the result if void.
5377 (print_command_1): implement it.
5379 * command.c: Remove #if 0'd code. Initialize all the fields
5380 in add_cmd (). Rename do_nothing_command to
5381 not_just_help_class_command, and make it externally visible.
5382 command.h: add user_commands to struct.
5383 * main.c (define_command): Don't overload c->function with a char
5384 string as well as a function pointer.
5386 * eval.c (evaluate_subexp): Reinstall tiemann changes to
5387 calling convention of value_struct_elt () that got dropped in
5390 * tm-sparc.h (FRAME_FIND_SAVED_REGS): move to sparc-xdep.c.
5391 sparc-tdep.c (sparc_frame_find_saved_regs): ditto.
5393 * tm-sparc.h (POP_FRAME): replace some constants with defines.
5395 * sparc-xdep.c (store_inferior_registers): defer stores to regs
5396 until a good time (e.g. when we are about to run the child),
5397 saving ptrace calls.
5398 * infrun.c (proceed): handle DO_DEFERRED_STORES.
5399 * tm-sparc.h: define DO_DEFERRED_STORES.
5401 * sparc-xdep.c (store_inferior_registers): when storing float
5402 registers, don't store stack regs too. When storing the SP,
5403 however, DO store the stack regs too. This fixes a bug in which
5404 the dummy frame is not recognized when a call_function finishes,
5405 because its frame pointer (in the stack regs) was never
5407 (read_inferior_registers): Mark WIM and TBR and FPS and CPS valid
5408 even though we don't know how to read them from an inferior.
5409 valops.c (call_function): Comment about storing SP.
5411 * infrun.c (save_inferior_status): Save away the original bpstat
5412 chain so it can be restored later. Install the copied version for
5413 use by whoever saved the status. It will be blow away by
5414 restore_inferior_status, and the original chain restored. This is
5415 important for people who have pointers into the original.
5417 * breakpoint.c, command.h, copying.awk, dbxread.c, defs.h,
5418 findvar.c, frame.h, obstack.h, obstack.c, inflow.c, value.h,
5419 main.c, printcmd.c, sparc-tdep.c, symtab.c, valprint.c: lint
5422 Fri Sep 28 20:32:46 1990 John Gilmore (gnu at cygnus.com)
5424 * Makefile.dist: Roll version to 3.91.8. Add bfd.h and bfdconfig.h
5425 temporarily to the makefile. Add am29k-opcode.h and WHATS.NEW.
5426 Add stuff.c and kdb-start.c to the OTHERS list for tar files.
5428 Fri Sep 28 19:12:12 1990 John Gilmore (gnu at cygint)
5430 * Merge Mike Tiemann's multiple inheritance changes from Sun.
5431 Store the baseclasses in a type struct starting from array element
5432 0 rather than from the unusual array element 1.
5434 dbxread.c: the above.
5435 (virtual_context): Add
5436 Read new debug information about which virtual function table
5437 a virtual function is from, and store it in fn_field.fcontext.
5439 symtab.h: Add fcontextt. Fix baseclass indices. Typo in
5440 TYPE_FN_FIELD_STATIC_P.
5442 symtab.c: the above.
5443 valops.c: the above. Handle pointer casts of object *'s.
5444 (search_struct_method): Add.
5445 (value_struct_elt): First arg is now a pointer to a value, and is
5448 valprint.c: the above.
5449 values.c (value_virtual_fn_field): Add type arg. Handle
5450 offsetting to the proper object when calling virtual fns.
5452 (baseclass_addr): Add valuep arg.
5454 * README: Document the current state of BFD config (missing).
5455 * TODO, ChangeLog, Makefile.dist: Roll version.
5456 * WHATS.NEW: Add summary of changes since 3.5.
5458 Thu Sep 27 16:23:12 1990 John Gilmore (gnu at cygint)
5460 * dbxread.c (read_struct_type): Clear bit vectors whenever
5462 symtab.c (B_CLRALL): define.
5464 * tm-sparc.h (STORE_RETURN_VALUE): Avoid clobbering types by
5465 using == rather than =. Huh... This fixes the dreaded problem
5466 wherein builtin_type_int becomes TYPE_CODE_FLT.
5468 * core.c (info_files): Show the inferior pid.
5470 * config.gdb: Avoid putting "dir" command into .gdbinit. GDB
5471 already knows how to look in the source directory.
5473 * Remove psymtab hair from many places. Remove duplicated code
5474 for searching symbol tables. Hide psymtabs from most places.
5475 Make it fast to get from a psymtab to its symtab.
5477 blockframe.c (blockvector_for_pc): Remove psymtab hair.
5478 coffread.c (psymtab_to_symtab): Rename to psymtab_to_symtab2.
5479 mipsread.c (psymtab_to_symtab): Rename to psymtab_to_symtab2.
5480 dbxread.c: export psymtab_to_symtab, make it work if called N times.
5481 (psymtab_to_symtab): Rename to psymtab_to_symtab2. Initialize
5482 new symtab completely. New psymtabs get symtab pointer
5483 initialized to zero. Remove MI warning printf.
5484 symtab.h: Comments. Add psymtab to symtab pointer.
5485 (PSYMTAB_TO_SYMTAB): New macro.
5486 symtab.c: use PSYMTAB_TO_SYMTAB. Add psymtab_to_symtab and export it.
5487 source.c: use PSYMTAB_TO_SYMTAB. Remove symtab version and
5489 stack.c (backtrace_command): Avoid pre-pass to read symbols, if
5491 (print_frame_info): Avoid special-casing symbols that have not yet
5494 * source.c (open_source_file): Quick path if we have already
5495 located the source file by its full name.
5497 * symtab.c (lookup_symbol): Use find_pc_symtab rather than
5498 find_pc_psymtab. When a name is found in the misc function
5499 vector, search the symbol table for its mangled name, not the
5500 name that the user typed.
5502 * bfd.h: Fix missing comment terminators, make #endifs match.
5504 * valarith.c (value_less): Handle unsigned int comparisons.
5505 Add FIXME about pointer compares, which assume host and target
5506 pointers are the same.
5508 * command.c (do_nothing_command): lint
5509 dbxread.c: lint. Remove sort_syms. Document C++ visibility info,
5510 fix comments on debug symbol format for visibility. Actually set
5511 visibility of symbols.
5512 main.c (echo_command): lint; use <readline/history.h>.
5513 tm-sparc.h (FRAME_FIND_SAVED_REGS): lint
5514 obstack.h (_obstack_blank): Rearrange pointer math to avoid
5515 pointing past end of allocated memory; saber complains.
5516 obstack.h: Declare the external functions that we use.
5517 valarith.h: use <string.h>
5518 solib.c (solib_add): lint.
5520 Fri Sep 21 17:05:19 1990 John Gilmore (gnu at cygint)
5522 * main.c (initialize_main): Default info_verbose to off, now that
5523 symbol reading is fast.
5524 (quit_command): Avoid clobbering exec_bfd while quitting.
5526 * Initial BFD (binary file diddling library) merger:
5527 coffread.c: Change AOUTHDR to struct exe_hdr.
5529 core.c: initialize initialized data at compile time.
5530 (core_file_command): Move from coredep.c, convert to bfd.
5531 (xfer_core_file): Convert to bfd.
5532 exec.c (exec_file_command): use bfd routines.
5534 mips-tdep.c: Remove exec_file_command and friends.
5537 * coredep.c: (fetch_core_registers) Convert core_file_command to
5538 fetch_core_registers.
5539 mips-xdep.c, sparc-xdep.c, sun3-xdep.c: ditto.
5541 * utils.c: (error): Bogus crap, FIXME, to print bfd errors.
5542 (my_bfd_read): More bogosity, which I don't think we call.
5543 (program_name): Remove this atrocity asap!
5545 Wed Sep 19 13:36:41 1990 John Gilmore (gnu at cygint)
5548 values.c: allocate_repeat_value was not clearing the
5549 optimized_out field.
5550 (value_static_field): minor stylistic fix (wrong macro was used).
5551 valops.c (value_struct_elt_for_address): didn't work for C++
5554 * signame.c (_initialize_signame): Initialize signal names once.
5556 * breakpoint.h, command.c, copying.awk, defs.h, environ.c,
5557 exec.c, frame.h, infcmd.c, inferior.h, main.c, munch, sun3-xdep.c,
5558 symtab.h, tm-29k.h, valprint.c, value.h, values.c: Lint.
5560 * remote-eb.c: Support user-settable baud rates on the serial port.
5562 * tm-sun3.h (PREPARE_TO_STORE): fix typo.
5564 Fri Sep 14 13:28:29 1990 John Gilmore (gnu at cygint)
5566 * tconfig/sun3os4: Remove warning about native assembler,
5567 since it also occurs in the xconfig file.
5569 * findvar.c (registers): Allocate some slop after `registers'
5570 to prevent stray accesses from trashing the next variable.
5572 * tm-68k.h (REGISTER_BYTES): Allocate the right number of bytes
5573 on the sun-3, by changing the #ifdef from `sun3' (which is not
5574 defined by cc) to `sun'. Symptom was trashed builtin_type_XXX
5575 vars, which happened to follow `registers' in the executable.
5577 * readline/history.c (history_search): Heed gcc-2's advice
5578 and parenthesize && inside ||).
5580 * am29k-opcode.h, am29k-pinsn.c, am29k-tdep.c, remote-eb.c,
5581 tm-29k.c: Insert FSF copyright headers.
5583 * remote-eb.c: Better comments.
5585 * Makefile.dist: Update to 3.91.6.
5586 * TODO: note PREPARE_TO_STORE problem.
5588 Thu Sep 13 09:52:33 1990 Jim Kingdon (kingdon at cygint)
5590 * stack.c (frame_info): Only use FRAME_FIND_SAVED_REGS if defined.
5592 * remote.c: Wrap the whole file in #if !defined (SPECIAL_REMOTE).
5594 * infrun.c (wait_for_inferior, at end): Don't set up
5595 prev_* if the inferior no longer exists.
5597 * inferior.h (CALL_DUMMY_LOCATION): New macro, to replace
5598 CANNOT_EXECUTE_STACK.
5599 valops.c (call_function): Use it.
5601 * tm-convex.h: Add CALL_DUMMY_LENGTH for use by PC_IN_CALL_DUMMY.
5603 * inferior.h (PC_IN_CALL_DUMMY): New macro.
5604 infrun.c (wait_for_inferior, 2 places): Use it.
5606 * values.c (value_being_returned): Only use
5607 EXTRACT_STRUCT_VALUE_ADDRESS if defined.
5609 * Move PREPARE_TO_STORE from xm-sun3.h to tm-sun3.h to do the
5610 right thing for remote-eb.c.
5612 * sun3-xdep.c: Remove extraneous call to remote_store_registers.
5613 * sun386-xdep.c, hp300hpux-xdep.c, sparc-xdep.c: Ditto.
5615 * blockframe.c: Put get_frame_saved_regs inside #if !defined
5616 (FRAME_FIND_SAVED_REGS).
5618 * findvar.c ({fetch,store}_registers): Check for
5619 REMOTE_{FETCH_STORE}_REGISTER macro.
5621 * findvar.c (get_saved_register): Add argument lval and
5622 change meaning of argument addr.
5623 findvar.c: Change calls to get_saved_register to reflect
5624 new calling convention.
5625 valops.c (value_assign): Use get_saved_register instead of
5626 find_saved_register.
5628 Sun Sep 2 12:40:20 1990 Jim Kingdon (kingdon at cygint.cygnus.com)
5630 * coffread.c (read_one_sym): Make temp_aux an AUXENT, not
5631 an (uninitialized) pointer to one. Use "&" when passing it
5634 Fri Aug 31 22:57:54 1990 Jim Kingdon (kingdon at cygint.cygnus.com)
5636 * coffread.c (getfilename): Use DGUX x_offset and x_name if
5639 * coffread.c (symbol_file_command): Put semicolon after
5641 Put safe_to_init_tdesc_context in #if defined (TDESC).
5642 Put #ifdef TDESCs in 1st column for non-ANSI cpp's.
5643 coffread.c: #include <sys/stat.h>.
5644 (read_coff_symtab): Typo: in_source_files -> in_source_file.
5645 Add missing ')' in check for "lc%" and friends. Remove
5647 Declare read_one_sym() at top of file.
5648 (read_file_hdr): Put in extra #ifdefs so MC68MAGIC and
5649 MC68WRMAGIC can have the same value without causing a duplicate
5652 Thu Sep 13 15:55:36 1990 John Gilmore (gnu at cygint)
5654 * Allow a Makefile to be built without building the
5655 tm and xm file links that screw up builds in subdirectories.
5656 This is done with `config.gdb none', then you can do things
5657 like `make gdb.tar.Z'.
5658 * tconfig/none: Config file for no target system
5659 * xconfig/none: Config file for no host system
5660 * config.gdb: If no TM or XM files are called out by the
5661 host or target file, don't make links for them.
5663 * cplus-dem.c: Add documentation.
5665 * dbxread.c (read_ofile_symtab): Turn a fatal error into a
5666 simple error, so the user's gdb doesn't crash due to some object
5667 file problem (e.g. somebody is rebuilding the file out from under
5670 * printcmd.c (print_address_symbolic): demangle the symbol.
5672 * Makefile.dist (OTHERS): Remove tdesc-lib because it has
5673 Motorola copyrights in it. Make "make gdb.tar.Z" work.
5674 (alldeps.mak): sort and uniq all results from this; duplicates
5675 hose gdb.tar.Z link building. Remove RCS files from
5676 tconfig and xconfig. Add config files for sun386. Add
5677 a few odd files to OTHERS and HFILES.
5679 Mon Sep 10 21:20:24 1990 John Gilmore (gnu at cygint)
5681 * Makefile.dist: Pull solib.c to tconfig/sun?os4.
5682 Roll version number to 3.91.5. Make lint work in bindir.
5684 * README: Document cross-debugging and new file structure.
5686 * blockframe.c: Lint. Include "value.h" to declare read_register.
5687 (find_pc_partial_function): remove duplicate line.
5689 * command.h: Lint. Declare error_no_arg and dont_repeat.
5691 * tm-news.h: Remove inadvertently duplicated stuff.
5693 * mipsread.c: Remove cache_pc_function stuff, now done cleanly.
5694 Clean up usage of misc_function_type. Declare some CORE_ADDRs.
5696 * config.gdb: Allow `config.gdb host target' form. Clean
5697 up previous change that printed bogus messages when you just said
5700 * core.c: #include "command.h" for lint.
5703 * main.c: Remove some casts of enums. Lint.
5710 * printcmd.c (initialize_printcmd): Fix thinko in inspect cmd.
5712 * sparc-tdep.c (isannulled): Take instruction as parameter, don't
5713 read it from memory. This will allow us to save ptrace calls
5714 eventually. Changed caller single_step too.
5716 * sparc-xdep.c (fetch_inferior_registers): Avoid reading regs
5717 that we aren't going to use, saving many ptrace calls, especially
5718 when watchpointing or single stepping. Use some #define's for
5720 (store_inferior_registers): Ditto.
5721 (core_file_command): Use some #define's for constants.
5723 * tm-sparc.h: Add #define's for some register numbers, so we
5724 can eliminate the use of random constants in sparc-xdep.c.
5726 * stack.c (frame_command, print_frame_info, up_command,
5727 down_command) Remove frame_changed, since it
5728 causes a bug and doesn't seem to do anything useful. In some
5729 places it was used as a flag, in others as a stack level (?).
5731 * utils.c: Use MISSING_VPRINTF rather than HAVE_VPRINTF, so the
5732 default is to use the portable (vprintf) version rather than the
5734 * xm-news.h (MISSING_VPRINTF): Add.
5736 * valprint.c (val_print): Demangle fancy vtbl printouts. Lint.
5738 Sat Sep 8 00:24:12 1990 John Gilmore (gnu at cygint)
5740 * Remove stuff that forces -Bstatic linking of gdb, and warnings
5741 about linking debugged programs -Bstatic in the sun?os4 config
5742 files in tconfig and xconfig subdirectories.
5744 * main.c (main): Remove unreached exit(0) now that we exit
5747 * Create TODO file for online bug list. There are too many
5748 "little" bugs to keep track of on paper.
5750 * Change Projects file to refer to bug-gdb@cygnus.com
5751 rather than kingdon@ai.
5753 Fri Sep 7 23:35:15 1990 John Gilmore (gnu at cygint)
5755 * Makefile.dist (VERSION): 3.91.4 now.
5757 * symtab.c (init_misc_bunches): Rename from init_misc_functions.
5758 (condense_misc_bunches): Add sanity check that misc_count is
5759 the same as the number of symbols in the bunch.
5761 * coffread.c: rename init_misc_bunches. Pass an argument
5762 to condense_misc_bunches (a zero).
5764 * dbxread.c (partial_symbol_file_read): Call init_misc_bunches
5765 every time we are called; don't rely on our caller to do it.
5766 (add_file): Remove call to init_misc_bunches.
5768 * mipsread.c: Only warn, don't error, if unknown symbol types.
5769 This keeps an old gdb from falling on its face if it sees newly
5770 extended symbol info. Rename init_misc_bunches.
5772 Fri Sep 7 22:58:15 1990 John Gilmore (gnu at cygint)
5774 * Merge in changes from Per Bothner for DECstations and other
5775 MIPS stuff. The rest is Bothner speaking:
5777 The next message is a merger of Alessando Forin's mips port with
5778 mine. I've tried to use my good if biased judgment to get
5779 the best of both. It *does* need testing.
5781 Some of the changes are general, *not* mips-specific.
5784 Didn't believe in little-endian bit order.
5785 There are still inconsistencies about whether flags
5786 like BITS_BIG_ENDIAN are integer (#if ...) or
5787 boolean (#ifdef ...). I tried to paper over them.
5789 dbxread.c,coffread.c,mipsread.c,symtab.c,symtab.h:
5790 Moved some misc_function code that was common to
5791 {dbx,coff,mips}read.c to symtab.c.
5792 In the process, I think I cleaned things up a bit.
5793 At the same time, moved obsavestring and obconcat to symtab.c.
5796 Removed obsolete condense_addl_misc_bunches (use
5797 condense_misc_bunches(1) instead).
5800 Needed to include <sys/dir>, at least on DECstations.
5802 valops.c, mips-tdep.c, tm-mips.h:
5803 Added PUSH_ARGUMENTS macro to support funny argument-pushing
5804 conventions (when STACK_ALIGN is insufficient).
5805 Needed on mips, where doubles need 8-byte alignment,
5806 but ints only need 4.
5809 Removed cruft that was not being used.
5810 Merged in many fixes (most from Frank Yellin, fy@lucid.com).
5813 Print $ before register-names (I think that makes things a little
5815 Never print two instructions, even if one delays.
5816 Removed hex-disassemble set_cmd. (This is not mips-specific,
5817 so I think the argument is whether it is generally worthwhile or not.
5818 I'm inclined to think not, given how easy it is to
5819 convert between radixes in gdb.)
5822 This is basically Alessando's code.
5823 It doesn't use obstacks; I changed it to use obstacks
5824 in a few minor places where using malloc causes a
5825 memory leak. (Probably, more places could/should be changed.)
5826 I added record_misc_function where it was missing.
5827 In symbol_file_command and add_file_command, I tried
5828 to make the code consistent with more recent versions.
5829 Minor sylistic changes in parse_procedure.
5830 Make a .gdbinfo. psuedo-symbol point back to the real
5831 procedure symbol (using the isym field).
5834 This is basically from my port, but with a lot of details
5835 and a number of routines merged in from Alessando's version.
5836 I basically used my code "raw" backtrace (use heuristics
5837 from the actual code, rather than symbol table info) - though
5838 the idea is Alessandro's. I feel my code is a little cleaner
5839 here, particularly in being a little more flexible, such as being
5840 able to handle gcc-produced code (which it now can).
5841 It also doesn't do frame caching (which is not useful
5842 more recent gdb versions).
5843 I also used my code for push_/pop_dummy, more or less.
5844 I tried to incorporate AF's code for testing sigtramp
5845 while backtracing; I probably got it wrong.
5846 Added mips_print_register, which tries to scrunch as much
5847 information as possible on a screen...
5848 Removed the skip-prologue set_cmd. As with hex-disassemble (see
5849 under mips-pinsn.c), I don't see anything mips-specific here,
5850 and I don't see it being all that useful anyway.
5853 Added a $fp psuedo-reg distinct from $fp (nice for gcc).
5854 Use more register names (rather than hard-cases numbers).
5856 Thu Sep 6 18:33:15 1990 John Gilmore (gnu at cygint)
5858 * Hack up 3.90.11 changes:
5860 * Makefile.dist (depend): parameterize $(GCC).
5861 Add solib.c and solib.o.
5862 (readline): Fix vpath for both absolute or relative SRCDIR.
5864 * blockframe.c: Fix from Schaefer@asc.slb.com for shared libs.
5865 Also, let the part I didn't understand at least compile so
5866 I can test the rest. FIXME.
5868 * dbxread.c: Fix thinko using strcmp.
5869 (init_psymbol_list): declare static.
5870 (partial_symbol_file_open): Comment cleanups better, avoid
5871 cleaning up the string table since the caller will do that.
5872 Move the stat for mod time into symbol_file_command, temporarily.
5873 (There should be a mod time for each symbol file, eventually,
5874 to control its rereading. FIXME.)
5876 * infptrace.c (PT_WRITE_D): use same value as PT_WRITE_I for
5877 SunOS, which gives error for shared libs otherwise. (From
5878 Schaefer, probably FIXME needs work for portability.)
5880 * solib.c: Move #include "param.h" to work.
5881 Lowercase all the Uppercase Letters In the Messages.
5882 (find_solib): Clean up inferior_so_name for debug printouts.
5883 Allow no argument, to mean all shared libraries.
5885 * symmisc.c: include param.h to get CLEAR_SOLIB.
5887 Wed Sep 5 18:00:08 1990 John Gilmore (gnu at cygint)
5889 * Merge in Kingdon's changes from FSF: the diffs from 3.90.9
5890 to 3.90.11. ChangeLog entries below are from this.
5892 Wed Jun 13 09:17:39 1990 Jim Kingdon (kingdon at mole.ai.mit.edu)

5898 Tue Jun 12 16:15:26 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5902 * Makefile.dist (gdb.tar.Z): Change linking of config so it works.
5904 Thu Jun 7 16:22:27 EDT 1990 Jay Fenlason (hack@ai.mit.edu)
5906 * sparc-opcode.h Added single-operand version of rett.
5908 Mon Jun 4 18:12:31 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5910 * m-sparc.h (REG_STRUCT_HAS_ADDR, STRUCT_ARG_SYM_GARBAGE):
5911 Put parens around gcc_p in expansion.
5913 Thu May 24 15:44:51 1990 Jim Kingdon (kingdon at mole.ai.mit.edu)
5915 * utils.c (lines_to_list): Return 10 if lines_per_page == 0.
5917 Wed May 23 16:36:04 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5919 * Changes for Sun shared libraries:
5920 blockframe.c (find_pc_partial_function): If a non-text symbol
5921 is found, set *address = pc - FUNCTION_START_OFFSET.
5922 breakpoint.c (insert_breakpoints) [DISABLE_UNSETTABLE_BREAK]:
5923 Disable breakpoints instead of giving an error.
5924 source.c (select_source_symtab): Initialize cs_pst.
5925 symmisc.c: Call CLEAR_SOLIB if defined.
5926 symtab.h: Make text{low,high} CORE_ADDR not int.
5927 (psymtab): New field addr.
5929 dbxread.c: Move DECLARE_FILE_HEADERS outside functions.
5930 (record_misc_function): Give correct type for N_DATA symbols.
5931 (condense_misc_bunches): do "misc_function_count = j" regardless
5933 Take code which is shared between symbol_file_command and
5934 add_file_command and put it into partial_symbol_file_{open,read}.
5935 Split add_file_command into add_file_command and add_file.
5936 Make psymtab_to_symtab read in the string table if the file
5938 Two new parameters to read_dbx_symtab and start_psymtab.
5939 tm-sunos.h: New file.
5941 Tue May 22 17:43:03 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5943 * infcmd.c: Change cont_command to continue_command and "cont"
5946 Mon May 21 14:41:41 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5948 * breakpoint.c (enable_breakpoint): Get value of watchpoint.
5950 * defs.h [sparc]: Use <alloca.h> regardless of __GNUC__.
5952 * values.c (USE_STRUCT_CONVENTION): Check for structures of
5953 size 1,2,4,8 rather than size < 8.
5955 * dbxread.c (dbx_lookup_type): Do f->length *= 2 as many times
5956 as necessary, not just once.
5958 * sparc-opcode.h: Add a bunch of new opcodes which Sun as supports.
5960 Thu May 17 15:04:09 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5962 * {t,x}m-sun386.h, sun386-xdep.c, {x,t}config/sun386
5964 * tm-news.h: Add CALL_DUMMY_*.
5966 * tm-68k.h: Remove duplicate comment at FRAME_FIND_SAVED_REGS.
5968 * config.gdb: In list_host, list_target, use ${i}, not $i.
5970 Tue May 15 21:27:12 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5972 * source.c (find_source_lines) [BROKEN_LARGE_ALLOCA]: Use xmalloc.
5974 * sparc-opcode.h: Change all store floating-point state register
5975 instructions to have the right match & lose fields.
5977 Sat May 5 12:39:18 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5979 * Makefile.dist: Move -I${srcdir} to GLOBAL_CFLAGS and pass
5981 config.gdb: If srcdir != ., create readline directory and
5982 copy a makefile into it.
5984 * wait.h, infrun.c: Change WRETCODE to WEXITSTATUS for
5985 consistency with POSIX.
5987 * breakpoint.c (bpstat_stop_status): Disable watchpoint
5988 when we exit its exp_valid_block.
5990 Tue Sep 4 11:46:46 1990 John Gilmore (gnu at cygint)
5992 * Makefile.dist: Bump version to 3.91.3.
5994 * Clean up handling of breakpoint commands (somewhat).
5995 Prompted by Tiemann bug report "cont 10" doesn't work any more.
5997 inferior.h: Add breakpoint_proceeded to inferior status struct
5998 and globals; save it and restore it.
5999 (clear_breakpoint_commands): Cleanup, remove old #define.
6001 infrun.c (clear_proceed_status): Set breakpoint_proceeded.
6002 (save_inferior_status, restore_inferior_status): handle it also.
6003 (proceed): Remove earlier code that set breakpoint_proceeded.
6004 It is now set only in clear_proceed_status.
6005 (clear_proceed_status): Cleanup, use bpstat_clear rather
6006 than clear_breakpoint_commands. No callers need the stop_bpstat
6007 between clear_proceed_status and proceed.
6009 infcmd.c: Add breakpoint_proceeded definition and comment.
6010 (cont_command, jump_command, signal_command): Move call to
6011 clear_proceed_status right next to call to proceed.
6013 breakpoint.c (bpstat_do_actions): Avoid clobbering our
6014 caller's argument while running down the chain of breakpoints.
6015 Use new variable "breakpoint_proceeded" to determine when
6016 a command that it executes moves the inferior past the
6018 (bpstat_clear): Handle NULL argument.
6019 (bpstat_clear_actions): Avoid useless call to
6020 breakpoint_auto_delete.
6021 (delete_breakpoint): Clean up bpstat's that are pointing to
6022 the deleted breakpoint from the stop_bpstat chain.
6023 (breakpoint_auto_delete): Simplify.
6025 * Clean up handling of EOF, error on stdin, etc. This was
6026 prompted by a network problem that caused gdb to go into an
6027 infinite loop filling up its malloc'd memory.
6029 main.c (return_to_top_level): Cleanup: call bpstat_clear_actions,
6030 not clear_breakpoints_commands, which is now gone.
6031 (main): If command_loop returns (e.g. from EOF on stdin), do
6032 a quit_command (looping back to command_loop if quit_command
6033 doesn't really quit).
6034 (command_loop): check result from command_line_input and
6035 exit if it returns NULL, rather than passing the NULL to
6037 (gdb_readline): Free malloc'd result space before returning
6040 * utils.c (query): Handle C-d to mean "yes", just as if the
6041 input was not a terminal. Also avoid infinite loop if EOF
6042 occurs in mid-input-line before newline. This allows
6043 query to be used at EOF on stdin with reasonable results.
6045 * infrun.c (proceed): Set breakpoint_proceeded.
6047 * values.c (value_as_long): Avoid infinite recursion for enums.
6048 (_initialize_values): Fix typo in help msg (kingdon).
6050 * Makefile.dist (RL_LIB): Use RL_LIB_DEP for dependencies,
6051 RL_LIB for linking. This allows -lreadline for linking
6052 and nothing for dependencies, once readline is a real library.
6054 * config.gdb: Jim Kingdon: give useful error message if the
6055 host or target type is not recognized.
6057 * defs.h (alloca): SPARC <alloca.h> does not declare alloca,
6058 it just defines it. Dumb, but deal with it.
6060 * Jim Kingdon suggests:
6061 in xconfig/sun3os4, CFLAGS should be XM_CFLAGS.
6063 Wed Aug 29 18:03:27 1990 John Gilmore (gnu at cygint)
6065 * Makefile.dist (VERSION): Bump version # to 3.91.2.
6067 * Clean up Bothner's changes.
6069 * blockframe.c (clear_pc_function_cache): New function.
6070 * blockframe.c: remake cache_pc_function_* static.
6071 * dbxread.c (symbol_file_command): remove references to
6072 cache_pc_function_* variables.
6073 * dbxread.c (read_struct_type): Use VOFFSET_STATIC.
6074 * printcmd.c: Avoid kludging a global variable (addressprint)
6075 to avoid printing the address of a string twice. Instead,
6076 pass the format letter 's' down low enough that it can be seen
6077 to avoid this problem.
6078 (print_formatted): Pass format arg to value_print.
6079 (restore_addressprint): Remove function.
6080 (do_examine): Avoid hacking addressprint, cleanups and such.
6081 (print_frame_args): Add a comment to a Bothner change.
6082 * symtab.h: define VOFFSET_STATIC and use it instead of "-1".
6083 * symmisc.c (free_all_symtabs): Call clear_pc_function_cache
6084 to wipe out the values cached in blockframe.c.
6085 * symtab.c (find_method): Add comment saying how big you must
6086 allocate to be "big enough". Per being terse again.
6087 * valprint.c (val_print): Handle format letter "s" to print
6088 strings without addresses. Add comment to vtbl printing code
6089 which casts with wild abandon. Rearrange reference-printing
6091 @0xaddr: value (print w/addressprint)
6092 value (print w/~addressprint)
6093 @0xaddr (parameter lists w/addressprint)
6094 or nothing (parameter lists w/o addressprint)
6096 Tue Aug 28 10:47:18 1990 John Gilmore (gnu at cygint)
6098 * Merge more changes from Per Bothner:
6100 Gdb's handling of TYPE_CODE_REF was so counter-C++ (and otherwise
6101 annoying) that I tried to improve it. Here are my suggestions.
6103 These patches all attempt to handle TYPE_CODE_REF (as in C++) better.
6106 Do automatic de-reference when taking the address of a reference.
6108 Don't deref_ref when printing parameter lists.
6110 More attempts at treating refernences properly.
6112 In val_print, if deref_ref==0, don't print dangling " = ".
6114 Add COERCE_REF macro, which de-references an REF.
6116 * Merge changes from Per Bothner:
6118 * Fixed (Sony news)-specific configuration problems.
6119 * Fixed other problems with using vanilla pcc and libc (enum problems;
6120 assumption that vsprintf exists).
6121 * Some major speed-ups (finc_pc_partial_function now caches a match;
6122 parsing avoids duplicate symbol_lookup calls).
6123 * Changed handling of baseclasses (no longer use baseclasses field
6124 of struct type, use the first n_baseclasses fields instead).
6125 * Various minor changes/fixes, most C++-related.
6128 Cache the most previous match from find_pc_partial_function.
6129 (Save both low and high ends of matching function's pc range.)
6130 This speeds up the loop of infrun.c:wait_for_inferior quite
6131 a bit, and makes step/next commands much zippier.
6133 Added an enum->int cast (otherwise, some compilers barf).
6135 No longer set baseclass offset to 0, since multiple
6136 inheritance now mostly works.
6137 Added a number of casts, to shut up compiler warnings
6138 (after stabs where made enums, not ints).
6139 When discarding a symbol table (in symbol_file_command),
6140 must clear the cache introduced in blockframe.c.
6141 Don't convert $vtbl_ptr_type to vtbl any more.
6142 Get rid of TYPE_BASECLASEES and baseclass_vec (see also symtab.h).
6143 Mask off sign bit emitted by g++ for virtual table offset.
6144 Set voffset to -1 (not 1) for static member functions.
6146 Changed parsing/lexing of names to avoid doing symbol lookup twice
6147 (once when lexing to determine symbol class, once for real).
6148 Now only call symbol_lookup once. Fields of 'this' win especially big.
6150 Subpress printing addr twice in the case of 'x/s addr'.
6152 lookup_basetype_type is no longer used.
6153 Add find_methods as recursive helper function to decode_line_1.
6154 This allows multiple inheritance to work.
6155 Also, once one or more matches has been found, do not look in
6156 base-classes. (Baseclass methods would be overridden, anyway.)
6158 Removed baseclasses array in struct type.
6159 Instead of using baseclasses[i], use fields[i-1].
6160 Added virtual_field_bits[i] to indicate if the i'th baseclass is virtual.
6161 Changed sign convention of voffset (previous was inconsistent).
6163 Some macros (CALL_DUMMY and relatives) were missing. Put them back.
6165 Used to assume existence of vsprintf. Re-written to not need it
6166 if HAVE_VPRINTF is undefined.
6168 typecmp was too pessimistic. Made it less so.
6170 Don't print space after address.
6171 If vtable points to a misc symbol (with 0 offset), print it,
6172 since that indicates the actual class of the object.
6173 Changed ype_print_derivation_info to use new inheritance
6174 scheme (without baseclasses vector).
6176 In value_primitive_field, fixed some bugs left over from previous set of fixes.
6177 Also, changes needed because TYPE_BASECLASSES were removed.
6179 REGISTER_U_ADDR didn't work for PC. Rewrote to use an array.
6181 Tue Aug 21 20:08:54 1990 John Gilmore (gnu at cygint)
6184 If there is no path set, and the symbols don't indicate what directory
6185 a file was compiled in, look in the current directory. But either
6186 a path or a known compilation directory will prevent this.
6189 Three independent bug fixes:
6190 * Remove the #if 0 block that breaks some stuff.
6191 * SunOS 4.1 fixed the promoted-parameter-wrong-addr bug in Sun C;
6192 adapt gdb to either SunOS 4.0.* or 4.1.
6193 * MAX_OF_TYPE and MIN_OF_TYPE thinko. By tedg@sun, I think.
6196 Instantiate the class T when looking for methods in it. (Tiemann@sun)
6199 (type_print) Demangle the name being printed.
6200 (type_print_base) Handle botched demangling without coredump (tiemann).
6203 (check_stub_method): Document routine.
6204 (tiemann) fix bug for no-arg functions
6205 Avoid clobbering beyond end of malloc'd storage.
6206 Terminate the argument list properly.
6208 Sat Aug 18 01:29:59 1990 Per Bothner (bothner@cs.wisc.edu)
6210 * Changes merged by John Gilmore:
6213 In breakpoint_1, use new print_address_symbolic instead
6214 of find_pc_partial_function. (This forces use of assembler-level
6215 addresses, and avoids misleading non-mangled source-level names.)
6217 Generalize ansi argument such that -1 means skip arglist totally.
6218 Removed global variable print_ansi_qualifiers (which made
6219 code non-reentrant), in favor of extra explicit arguments
6220 to internal routines.
6222 Add new helper function print_address_symbolic.
6223 Use find_pc_misc_function instead of find_pc_partial_function
6224 (since we want assembler-level symbols here).
6226 Print unknown function as just "f (...)", not "f (...) (...)".
6227 Use new fputs_demangled explicitly.
6229 Fixed a typing violation (problem: value.h cannot be imported
6230 without renaming many variable in this file).
6231 lookup_symbol: If no matching misc_func, look for a C++-mangled name.
6232 decode_line_1: Moved forward some never-reached code.
6233 Made decode_line_2 skip function prologues correctly.
6235 fputs_filtered should not demangle by default.
6236 Add new fputs_demangled to demangle on demand..
6238 Change value_struct_elt to use value_primitive_field (using recursive
6239 utility function search_struct_field). This allows foo.bar to work
6240 for multiple inheritance (so far only for data fields).
6241 Change check_field in the same way (recursive helper function
6242 to support multiple inheritance).
6243 (Note: there are more of these problems that I haven't fixed.
6244 Any code that says TYPE_BASECLASS (t, 1) is probably wrong.)
6245 value_of_this: 'this' symbol name is now just "this", note "$this".
6247 Don't print static members.
6248 Avoid printing "members of <type>" if there are none.
6249 Simplified type_print_derivation_info by merging duplicate code.
6250 Remove useless blank lines in type_print_base (ptype command).
6252 Added declaration of new routine value_primitive_field.
6254 Added value_primitive_field which is generalized version of
6255 value_field that can handle multiple inheritance (non-zero offsets etc).
6256 Re-implemented value_field to call value_primitive_field.
6258 Fri Aug 17 23:33:44 1990 John Gilmore (gnu at cygint)
6260 * infcmd.c -- insert else to avoid 'delete env' coredump when you
6261 delete the whole environment. Karl Berry reported the bug.
6262 * source.c - fix openp to avoid //'s in filenames, which
6263 trigger an Emacs bug causing it to not be able to find files
6264 when running gdb in a window.
6265 * dbxread.c - zap the #if 0 that botches the add-file code.
6266 It seems to work a lot better without all the code commented out.
6268 Fri Jul 20 16:58:46 1990 John Gilmore (gnu at cygnus.com)
6270 * Merge Tiemann's and Ted Goldstein's changes, detailed below,
6273 Tue Jul 17 19:34:33 1990 Ted Goldstein (tedg at golem)
6275 * Makefile - added a ${CFLAGS} to a couple of entries,
6276 added remote-sa.sparc.c
6277 * added remote.sa-sparc.c, a modification of remote.c
6278 which conducts a dialog directly with the SparcStation prom.
6279 * breakpoint.c, infrun.c, sparcdep.c added
6280 remote_insert_breakpoint(), and remote_remove_breakpoint()
6281 to breakpoint.c instead of directly writing breakpoint instructions.
6282 * sparcdep.c on remote_debugging,there is no need
6283 to remove signle step breakpoint instructions.
6284 * main.c added "-epoch" flag and "int epoch_interface" to main.c
6286 * printcmd.c - epoch interface sends lisp expressions to open up
6287 epoch windows on inspection.
6288 * valprint.c - added arrayprint, and addressprint and made adding
6289 format controls easier
6290 * wait.h added a couple of undef's because we were getting
6291 complaints about WSTOPSIG and WTERMSIG begin redefined.
6294 Wed Jul 4 05:27:51 1990 Michael Tiemann (tiemann at masham)
6296 * symtab.c (decode_line_1): Add support for handling method stubs
6297 in the type information.
6299 Tue Jul 3 09:39:18 1990 Michael Tiemann (tiemann at masham)
6301 * values.c (baseclass_addr): Run loop from INDEX+1 to
6302 N_BASECLASSES; otherwise, we can still get into a loop.
6303 @@ This should be restructured to use a cleaner search strategy.
6305 Sun Jul 1 12:28:51 1990 Michael Tiemann (tiemann at masham)
6307 * dbxread.c (define_symbol,read_type): Grok GNU C++'s new
6308 abbreviation "Tt" for tags which have the same name as their
6311 Fri Jun 29 01:03:46 1990 Michael Tiemann (tiemann at masham)
6313 * symtab.c (list_symbols): add ability to set breakpoints on all
6314 the functions which match a particular regular expression.
6316 Tue Jun 26 04:26:29 1990 Michael Tiemann (tiemann at masham)
6318 * cplus-dem.c (cplus_demangle): New parameter ANSI says whether we
6319 should print ANSI qualifiers (such as `const' and `volatile').
6320 All callers changed to call with ANSI == 1, except from
6321 `check_method_stub', which uses old-style syntax.
6323 * symseg.h (struct fn_field): Remove unneccessary `args' field.
6324 * symtab.h (TYPE_FN_FIELD_ARGS): Redefined.
6326 * values.c (check_stub_method): New function.
6328 * cplus-dem.c (do_type): Handle "long long" (encoded as 'x').
6330 * dbxread.c (read_type): Handle new GNU C++ method type stubs.
6331 * valprint (type_print_base): Ditto.
6333 * symtab.c (gdb_mangle_typename): New function.
6335 Tue Jun 5 00:18:43 1990 Michael Tiemann (tiemann at gzilla)
6337 * breakpoint.c (catch_command): New function. Provides a
6338 mechanism to set breakpoints based on catch clauses.
6339 (disable_catch): Similar, but disables breakpoints on catch
6341 (delete_catch): Similar, but deleted breakpoints on catch clauses.
6343 Sun Jun 3 22:54:08 1990 Michael Tiemann (tiemann at gzilla)
6345 * blockframe.c (blockvector_for_pc): New function.
6346 * blockframe.c (block_for_pc): Changed to call
6347 `blockvector_for_pc' and get the block itself.
6349 * stack.c (catch_info): New function. Prints info about
6350 exceptions which can be caught in the current frame.
6351 * stack.c (print_frame_label_vars): New function. Similar to
6352 `print_frame_local_vars'.
6353 * stack.c (print_block_frame_labels): Prints out labels that are
6354 defined in this frame. These labels are exceptions that can be
6357 * dbxread.c: Updated to handle N_CATCH symtab types.
6359 Thu May 3 22:10:00 1990 Michael Tiemann (tiemann at teacake)
6361 * valprint.c (everywhere): TYPE_NAME (TYPE) no longer comes in the
6362 form "struct ..." for GNU C++. Don't flush any part of TYPE_NAME
6363 when printing the type.
6365 Wed May 2 22:43:04 1990 Michael Tiemann (tiemann at teacake)
6367 * valprint.c (val_print): Use `baseclass_addr' to access the
6368 baseclasses pointed to via the derived class object at VALADDR.
6370 * values.c (baseclass_addr): New function. Casts derived pointers
6371 to baseclass pointers taking virtual baseclasses and multiple
6372 inheritance into account.
6374 Sat May 5 12:39:18 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
6378 Fri May 4 12:12:55 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
6380 * breakpoint.c (watch_command, bpstat_stop_status): Deal with
6381 exp_valid_block field correctly.
6383 * infrun.c (wait_for_inferior): When checking "don't even think
6384 about breakpoints" if stop_signal == SIGTRAP && trap_expected,
6385 also check step_resume_breakpoint.
6386 Insert breakpoints and continue (not step) if
6387 step_resume_break_address != NULL, even if another_trap.
6388 If trap_expected and we enter sigtramp, then set up a
6390 If trap_expected is set when we hit the step_resume_break,
6392 When calling resume and trap_expected says tell resume to step
6393 (2 places), also check step_resume_break_address.
6395 * infrun.c (wait_for_inferior): Don't set
6396 prev_{pc,sp,func_{start,name}} before calling wait ().
6397 Do set them after exiting loop.
6398 Move their declarations outside functions.
6399 (start_inferior): Initialize them.
6401 Thu May 3 00:15:11 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
