1 Thu Nov 21 10:23:52 1991 John Gilmore (gnu at cygnus.com)
3 * defs.h: Incorporate param.h. All users changed.
4 * param-no-tm.h: Change users to define TM_FILE_OVERRIDE instead.
5 * param.h, param-no-tm.h: Removed.
6 * Update copyrights in all changed files.
7 * dbxread.c, dwarfread.c, inflow.c, infrun.c, m2-exp.y, putenv.c,
8 solib.c, symtab.h, tm-umax.h, valprint.c: Lint.
9 * tm-convex.h, tm-hp300hpux.h, tm-merlin.h, tm-sparc.h,
10 xm-merlin.h: Avoid host include files in target descriptions.
11 * getpagesize.h: Removed, libiberty copes now.
13 Wed Nov 20 18:35:56 1991 John Gilmore (gnu at cygnus.com)
15 * Remove gdb/hp-include. Support for HP a.out oddities should be
16 in BFD, not in GDB. Move gdb/hp-include/a.out.h to include/a.out.hp.h.
18 * infptrace.c, tm-sun386.h: Cashier <a.out.gnu.h>, remove refs.
20 * configure.in, xconfig, tconfig, Makefile.in, doc/gdbint.texinfo:
21 Makefile fragments for various hosts and targets now come from
22 gdb/config/mh-* and gdb/config/mt-*. This is for consistency with
25 * rs6000-pinsn.c, rs6k-opcode.h: Clean up.
26 * rs6k-opcode.def: Delete.
28 Wed Nov 20 05:04:40 1991 Fred Fish (fnf at cygnus.com)
30 * dwarfread.c: Recognize obsolete form of AT_element_list
31 attribute still used by at least one AT&T compiler, and possibly
34 Tue Nov 19 07:53:55 1991 Fred Fish (fnf at cygnus.com)
36 * dwarfread.c (enum_type, struct_type): Ignore names invented by
37 helpful compilers for anonymous structs, unions, and enums.
39 * c-exp.y, m2-exp.y: Add defines for yymaxdepth, yy_yys, and
40 yy_yyv, so multiple parsers produced by SVR4 versions of yacc
41 can coexist in the same executable without collision.
43 * symtab.h: Add declaration for lookup_template_type() to kill
44 compiler warnings about conversions from int to pointer.
46 Mon Nov 18 17:45:18 1991 Fred Fish (fnf at cygnus.com)
48 * procfs.c: Move inclusion of defs.h to before param.h, as in
49 all the other source files that include both. This is required
50 to supply some typedefs that are used in files included by param.h.
52 * m68k-tdep.c (m68k_skip_prologue): Add generic m68k support for
53 skipping function prologues, ala the other cpu families (i386,
54 mips, m88k, etc). Add the ability to skip movm and fmovm
55 instructions in the prologues. Still needs support for profile
56 (-p compiled) prologue sequences (FIXME).
58 * tm-68k.h: Change SKIP_PROLOGUE macro to use the new generic
59 m68k prologue skipping function by default.
61 * tm-altos.h, tm-isi.h: Continue to use the old definition of
64 Mon Nov 18 15:12:45 1991 John Gilmore (gnu at cygnus.com)
66 * Makefile.in: Remove tdesc stuff, and extra blanks before colons.
67 * blockframe.c: Remove tdesc-related code. Default
69 * infrun.c: Remove tdesc-related code.
70 * m88k-tdep.c (frame_chain_combine, init_frame_pc): Remove copies
71 of defaultable things.
72 * tm-m88k.h: New file, common to all Moto 88k target configs.
73 Derived from tm-delta88.h.
74 * tm-delta88.h: Use it.
75 * xm-m88k.h: Common file for 88K hosts. Remove obsolete stuff.
76 * xm-delta88.h: Use it.
77 * tm-*.h: Remove FRAME_CHAIN_COMBINE macros, since all are
79 * coffread.c: Remove tdesc stuff.
80 * tconfig/delta88, tconfig/m88k: Remove tdesc stuff.
81 * xconfig/m88k: Rename tm-88k.h to tm-m88k.h.
83 Mon Nov 18 13:51:37 1991 Per Bothner (bothner at cygnus.com)
85 * source.c (open_source_file): If openp fails, try again
86 using just the base (non-directory) part of the filename.
87 This solves various annoying problems, such as when the
88 source was compiled with an absolute pathname - and the
89 source files have moved. Or if the source was compiled
90 using a relative pathname, it can be more convenient
91 to just specific the source directory to the dir command.
93 Mon Nov 18 00:04:41 1991 Fred Fish (fnf at cygnus.com)
95 * cplus-dem.c (munge_function_name): Add missing third arg to
96 instance of call to do_type().
98 * dwarfread.c: Changes to match new dwarf.h. Remove
99 AT_deriv_list, AT_loclist, AT_incomplete, AT_const_data,
102 Sun Nov 17 16:20:53 1991 Michael Tiemann (tiemann at rtl.cygnus.com)
104 * symtab.h (struct type): Moved C++-specific fields into new type
105 `struct cplus_struct_type'. Now takes 10% less memory. Many
107 * symtab.c (init_type): Don't set fields belonging to
108 TYPE_CPLUS_SPECIFIC unless TYPE is TYPE_CODE_STRUCT.
109 * buildsym.c (read_type): Allocate TYPE_CPLUS_SPECIFIC for
111 (read_struct_type): Ditto. Also, add comments about how we can
112 deduce TYPE_VPTR_FIELDNO from inheritance info and fieldname info.
113 * coffread.c (decode_base_type): Allocate TYPE_CPLUS_SPECIFIC for
115 (read_struct_type): Ditto.
116 * dwarfread.c (struct_type): Ditto.
118 * symtab.c (read_range_type): Don't set TYPE_MAIN_VARIANT.
119 (lookup_pointer_type): Don't use or set TYPE_MAIN_VARIANT.
120 (lookup_reference_type): Ditto.
122 * cplus-dem.c: Many changes made to handle decoding of
124 * symtab.c (gdb_mangle_name): Mangle/demangle ANSI-mangled names

129 * mipsread.c (parse_partial_symbols): patch to keep DEC C
130 compiler from making gdb bomb out. Thanks to Ed Santiago!
132 Thu Nov 14 19:27:30 1991 Fred Fish (fnf at cygnus.com)
134 * symfile.c: Add function compact_misc_function_vector() to
135 remove duplicate misc function vector entries. See comments
136 in source for why this is necessary/desirable.
138 * dwarfread.c: Add misc function type parameter to internal
139 record_misc_function(). Remove calls to init_misc_bunches()
140 and condense_misc_bunches(), these are now done in elfread.c.
142 * elfread.c: Add support for reading bfd canonical symbol tables
143 and generating misc function vector entries for global and
144 absolute symbols. Do calls to init_misc_bunches() and
145 condense_misc_bunches() where they will enclose all calls to
146 record_misc_function(), including those in dwarfread.c.
148 Thu Nov 14 17:02:11 1991 Roland H. Pesch (pesch at cygnus.com)
150 * doc/Makefile.in: new targets gdb.me, gdb.ms, gdb.mm
151 (roffable documentation).
152 * doc/gdb.texinfo: embedded hints (as comments) for better
153 texi2roff conversion.
155 Thu Nov 14 13:18:25 1991 John Gilmore (gnu at cygnus.com)

165 gdb.z into the right place.
167 Wed Nov 13 16:45:13 1991 John Gilmore (gnu at cygnus.com)
169 Motorola 88000 port without tears, I mean without tdescs.
171 * m88k-tdep.c: Blow away all tdesc stuff.
172 Provide functions for all the frame-related macros in
173 tm-delta88.h. Adopt i960-style EXTRA_FRAME_INFO.
174 (examine_prologue, frame_find_saved_regs, skip_prologue): borrow
175 from i960-tdep.c and adapt to the function prologues on the 88k.
176 (read_next_frame_reg): Borrow from mips-tdep.c.
177 FIXME: frame_locals_address should go away.
179 * tm-delta88.h: Dump all the tdesc stuff.
180 Macros for all frame-related stuff call fns of same name.
181 Remove duplicated definitions. FP_REGNUM becomes same as
184 * xm-88k.h: Eliminate lots of library dependencies, now handled
185 in libiberty. Eliminate KDB nonsupport.
187 * doc/gdbint.texinfo: Add rudiments on frames. FIXME, add more.
190 * stack.c (frame_info): Mark frameless functions.
191 Print locals address (FIXME, remove if same).
192 * blockframe.c: Comment changes, FIXME after.
193 * coffread.c: Even without TDESC, need to zap "@" symbols.
194 Don't register for wierd format names; change the names in BFD.
196 * alloca.c, language.c, tdesc.c: Lint.
197 * tdesc.c, tdesc-lib: FIXME: remove these.
199 Tue Nov 12 19:30:22 1991 John Gilmore (gnu at cygnus.com)
201 * Makefile.in: Add tdesc library support. Fixups to lint,
204 Tue Nov 12 13:43:26 1991 Per Bothner (bothner at cygnus.com)
206 * symtab.c (decode_line_1): Remove spurious call to operator_chars.
208 Allow setting breakpoints on C++ destructors.
209 * valops.c (destructor_name_p): Don't check TYPE_HAS_DESTRUCTOR,
210 since it lies. Rely on callers to catch missing destructors.
211 * symtab.c (decode_line_1): For example (see above), here.
212 * buildsym.c, symtab.h: Remove TYPE_FLAGS_HAS{CON,DE}STRUCTOR
213 flags since they are no longer used.
215 Fixes to support C++ methods with functional parameters.
216 * c-exp.y (func_mod rule): Allow (and ignore) list of parameter
217 types in a function type.
218 * eval.c (parse_and_eval_type), value.h: New function,
219 parse_and_eval_type, is based on old code from check_stub_method.
220 But don't actually evaluate the cast, since that calls
221 value_cast(), whcih may fail. Just extract the type
222 from the parsed expression.
223 * values.c (check_stub_method): While looping through the
224 arguments, adjust depth *after* parameter has been handled.
225 Replace call and setup of parse_and_eval with new function
228 Tue Nov 12 09:40:07 1991 Fred Fish (fnf at cygnus.com)
230 * utils.c, rem-multi.shar: Remove fixed arg count version of
233 * altos-xdep.c, arm-xdep.c, coffread.c, command.c, convex-xdep.c,
234 core.c, dwarfread.c, gould-xdep.c, infcmd.c, language.c,
235 m88k-xdep.c, main.c, printcmd.c, pyr-xdep.c, source.c,
236 sun386-xdep.c, symm-xdep.c, umax-xdep.c, values.c, xcoffread.c:
237 Change all instances of use of fixed args concat() to variable
238 args concat() now located in libiberty.
240 Tue Nov 12 07:23:46 1991 John Gilmore (gnu at cygnus.com)
242 * Makefile.in: Add xcoffread.c, xcoffexec.c.
243 * xcoffread.c: New file for handling AIX mangled-coff files.
244 * xconfig/rs6000, tconfig/rs6000: New files.
245 * buildsym.c: Add hooks for xcoffread.c.
246 * rs6000-pinsn.c, rs6000-tdep.c, rs6000-xdep.c, tm-rs6000.h,
247 xm-rs6000.h, rs6k-opcode.def, rs6k-opcode.h: New files.
248 * xcoffexec.c: New file for handling AIX shared libraries.
250 Mon Nov 11 19:14:31 1991 Fred Fish (fnf at cygnus.com)
252 * core.c: Minor rewording of message to user containing name of
253 (and possibly arguments to) the program that generated a core
256 * elfread.c: Remove the register_addr() stub now that it is no
259 * procfs.c: Move misplaced #endif for ATTACH_DETACH. Add new
260 fetch_core_registers() function for core file support.
262 Sat Nov 9 13:37:57 1991 Fred Fish (fnf at cygnus.com)
264 * dwarfread.c (dwarf_psymtab_to_symtab): Remove leftover call
265 to do_cleanups() which resulted from a previous change.
267 * elfread.c: Re-enable compilation of register_addr() stub
268 whenever it is not supplied by coredep.c
270 Sat Nov 9 00:40:32 1991 John Gilmore (gnu at cygnus.com)
272 Add tracking of object files (that contain symbols) to gdb.
273 This includes a "struct objfile" that owns symtabs and psymtabs
274 that were read in from that binary file.
276 * symfile.h: Add struct objfile. Add pointer to the objfile
277 into the struct sym_fns.
278 Replace global `symfile' and `symfile_mtime' with
279 `symfile_objfile'. Add global object_files chain.
281 * symfile.c: Move param.h above symtab.h.
282 (sort_misc_function_vector): Add.
283 (syms_from_objfile): Was syms_from_bfd.
284 (symfile_open): Now returns objfile.
285 (allocate_objfile): New.
286 (free_objfile): New, replacing free_all_.*symtabs.
287 (symfile_init): Takes objfile arg, puts it in sym_fns result.
288 (reread_symbols): Searches whole chain of objfiles.
289 (allocate_symtab): Takes objfile as new parameter, chains them.
290 Handle INIT_EXTRA_SYMTAB_INFO.

293 * dbxread.c: Make more errors into complaints.
294 (push_subfile, pop_subfile): Move to buildsym.c.
295 (dbx_symfile_read, dbx_symfile_init, fill_symbuf, read_dbx_symtab,
296 start_psymtab, psymtab_to_symtab_1, read_ofile_symtab,
297 dbx_psymtab_to_symtab, ): Use bfd ops, don't use file descriptor.
298 Pass objfile. Change callers.
299 (fill_symbuf, SWAP_SYMBOL): Take bfd as arg.
300 (read_dbx_symtab): Just wipe out new symbols, not all, on error.
301 (end_psymtab): Blow away psymtab if empty.

306 * buildsym.c (end_symtab): Pass objfile.
307 (dbx_lookup_type): Handle null typevector.
308 (dbx_alloc_type): Check file number, not sym number, for -1.
309 (find_symbol_in_list): Add for xcoffread.
310 (start_symtab): Default typevector is empty. Keep reusing same
312 (end_symtab): Take objfile argument and pass it to
313 allocate_symtab. Don't make a symtab if no blocks or symbols.
314 Handle empty typevector.
315 (push_context): New function for context stack nesting.
316 (read_type): Mark FIXME where we need to reintroduce type smashing.
318 * buildsym.h (pop_context): Macro, paired with push_context.
319 (subfile_stack): Move here from dbxread.c.
321 * coffread.c (end_symtab, read_coff_symtab): Take and use objfile arg.
322 (read_coff_symtab): Cleanup by freeing objfile, not all symtabs.
324 * mipsread.c (read_mips_symtab, parse_partial_symbols, parse_fdr,
325 new_psymtab, new_symtab): Take and use objfile arg.
327 * dwarfread.c (scan_compilation_units, start_psymtab,
328 process_dies, end_symtab, dwarf_build_psymtabs,
329 read_lexical_block_scope, read_func_scope, read_file_scope): Take
330 and use objfile argument.
331 (psymtab_to_symtab_1, read_ofile_symtab): Don't take or use file
332 descriptor. Use BFD internal functions instead.
333 (end_symtab): Call global allocate_symtab.
335 * elfread.c, target.c: Minor changes to accommodate objfiles.
336 * symtab.h: partial_symbol_table has no symfile_name member now.
337 (fn_fieldlists voffset): avoid non-int bitfield.
338 (struct symtab): Add objfile * and objfile_chain * of symtabs.
339 (struct partial_symtab): Add objfile * and objfile_chain * of
340 psymtabs. Remove symfile_name.
342 * symmisc.c: Lose free_all_symtabs, free_all_psymtabs.
343 (printsyms_command): Rename from print_symtabs. Add selective
344 listing if 2nd argument given. Print objfile info.
345 (printpsyms_command): Rename from print_partial_symtabs. Ditto all.
346 (printobjfiles_command): New; prints objfiles lists, and checks
347 for consistency of symtab, psymtab, and objfile lists.
349 * symfile.h, symfile.c, symtab.h: Lint
351 Fri Nov 8 23:38:48 1991 John Gilmore (gnu at cygnus.com)
353 * command.c: Include param.h.
354 * defs.h (warning_setup, warning): Declare.
355 * expprint.c (print_subexp, UNOP_MEMVAL case): Lint.

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

750 * dbxread.c (read_enum_type): Avoid Modula-2 kludge that breaks C
752 * i387-tdep.c (double_to_i387): Fix typo for double_to_ieee_extended.
753 * utils.c (_initialize_utils): If !ISATTY, don't paginate.
754 * configure.in, tconfig/decstation, xconfig/decstation: Rename
755 dec3100 to decstation.
757 Mon Oct 14 13:37:50 1991 Roland H. Pesch (pesch at cygnus.com)

760 (nodes Continuing and Stepping; Memory; Targets) clarifications
763 Fri Oct 11 23:27:06 1991 John Gilmore (gnu at cygnus.com)
765 * tm-{irix3,mips,nindy960,pn,symmetry,vx960}.h: Move
766 REGISTER_U_ADDR to corresponding xm- file. Sugg. by Peter Schauer.

771 generic routines for calling inferior functions.
773 * blockframe.c (inside_main_scope, inside_entry_scope): New.
775 * copying.awk: Filter formfeeds out of copying & warrantee.
776 Make them available as `show copying' and `show warrantee' also.
777 * main.c (print_gnu_advertisement): Advt `show' commands.
779 Thu Oct 10 17:25:47 1991 John Gilmore (gnu at cygnus.com)
781 * mach386-xdep.c: Even when cross-compiling, leave in the
782 core-file reading code.
783 * core.c (get_core_registers): Avoid coredump if no .reg section.
785 Wed Oct 9 17:03:34 1991 John Gilmore (gnu at cygnus.com)
787 * mipsread.c, coffread.c: initialise TYPE_VPTR_FIELDNO to -1.
788 This avoids coredumps under `set print object on' in value_headof
789 (called erroneously by value_from_vtable_info) for `p &struct'
790 or `p *struct'. From Peter Schauer.
792 Mon Oct 7 00:06:52 1991 John Gilmore (gnu at cygnus.com)
794 * Makefile.in: Roll version to 4.1.2.
795 * dbxread.c: Use aout64.h, not a.out.gnu.h. Get external symbol entry
796 size from BFD (but, FIXME, we don't yet read external nlists's and
797 convert them to internal nlists's before handling them -- we still
798 assume they have the same size and alignment.) Use SET_NAMESTRING
800 * exec.c (exec_file_command): Move dead coff-encapsulation code
802 * m88k-tdep.c, m88k-xdep.c: Remove encap test and #inc <a.out.h>.
804 Fri Oct 4 22:30:06 1991 John Gilmore (gnu at cygnus.com)
806 * configure.in, tm-i386v.h, xm-i386v.h: Intel 386 Mach host port.
807 * xm-i386mach.h, mach386-xdep.c, xconfig/i386mach: New files.
809 Fri Oct 4 17:04:31 1991 Per Bothner (bothner at cygnus.com)
811 More patches from Peter Schauer <pes@regent.e-technik.tu-muenchen.de>:
812 * mips-xdep.c (store_inferior_registers): Don't try to
813 write the (pseudo) FP.
814 * mipsread.c (parse_partial_symbols): Improved algorithm for
815 setting pst->texthigh.
817 Fri Oct 4 16:47:32 1991 Roland H. Pesch (pesch at cygnus.com)
819 * doc/Makefile: make TEXINPUTS include . everywhere
821 Fri Oct 4 00:35:56 1991 John Gilmore (gnu at cygnus.com)
823 * coffread.c, dbxread.c, symfile.c, symmisc.c, symtab.h: Remove
824 vestiges of typevectors, which were for symsegs and are no longer
825 used. (From a question by Eliot Dresselhaus
826 <dresselh@RFT30.nas.nasa.gov>).
828 Thu Oct 3 09:33:26 1991 John Gilmore (gnu at cygnus.com)
830 * dbxread.c, coffread.c: static-ize functions that were
831 gratuitiously external. (From Fred Fish.)
833 * c-exp.y: sym->class to SYMBOL_CLASS (sym).
835 * dbxread.c (dbx_lookup_type): Keep doubling size of typevector
836 until it is large enough.
838 * dbxread.c (read_type): Handle error case slightly better.
839 Make complaint message not C++-specific.
841 Wed Oct 2 17:21:07 1991 Stu Grossman (grossman at cygnus.com)
843 * infrun.c (wait_for_inferior): Fix step/next so that you only
844 stop at the beginning of a new line. This fixes various problems
845 with for loops, nested if-else's and switch statements.
847 Tue Oct 1 06:33:55 1991 John Gilmore (gnu at cygnus.com)
849 * symtab.c (lookup_symtab_1, lookup_symbol): "fatal" errors
850 between symtabs and psymtabs become ordinary error()s.
852 * dbxread.c (read_dbx_symtab): Relocate end_of_text_addr
853 properly, making "end pc" correct in shared lib psymtabs.
854 (From Guy Harris <guy@auspex.com>.)
856 Mon Sep 30 13:15:31 1991 John Gilmore (gnu at cygnus.com)
858 * dbxread.c: Enable, but soften, const_vol_complaint.
859 (read_dbx_symtab): N_STSYM and N_LCSYM define static vars.
860 Ditto Gould N_NBSTS and N_NBLCS. Also, all types in the psymtab
861 should be file-scope, not global.
862 (read_struct_type): Remove ancient multiple-inheritance warning.
863 (read_range_type): Check base type, complain & patch if undefined.
864 * stack.c (frame_info): Demangle the function name in `info stack'.
867 Sat Sep 28 10:02:33 1991 John Gilmore (gnu at cygnus.com)
869 * eval.c (evaluate_subexp_for_address): Don't use
870 TYPE_POINTER_TYPE directly (it might be zero if this type has
871 never had a pointer created before); use lookup_pointer_type.
872 * symtab.c (lookup_method_type): Arguments were swapped in all
873 callers, so fix it here. I'm amazed this worked at all!
875 Fri Sep 27 18:09:31 1991 John Gilmore (gnu at cygnus.com)
877 * c-exp.y, m2-exp.y: Define more yysymbols that happen to be
878 "bss" rather than "data" symbols, but which still conflict.
881 * coffread.c (coff_symfile_read): Use xmalloc, not malloc.
882 * core.c (core_files_info): Shorten output.
883 * exec.c (exec_files_info): Ditto.
884 (build_section_table): Ignore zero-length sections.
885 * language.c, printcmd.c: Lint.
886 * language.h (get_frame_language): Declare.
887 * saber.suppress: update.
888 * stack.c (find_relative_frame): Remove complex code that was
889 #if 0'd, stick with simple code. Lint.
890 * saber.suppress: Update a bit.

892 * utils.c (parse_escape): Avoid \a due to bdead compilers.
893 * value.h: Declare typedef_print.
895 * valprint.c (val_print, type_print_base): TYPE_CODE_RANGE less
898 * nindy-tdep.c (nindy_frame_chain_valid): Use lookup_misc_func.
899 (Reported by Mark Peek <mark@imagen.com>.)
901 * solib.c (solib_map_sections): Relocate all sections, even
902 though only the text section's size is tracked. Mark ld_text
903 for eventual elimination as we generalize to N sections.
905 * infrun.c (wait_for_inferior): Don't check if the PC is in a
906 call_dummy if we were stopped by a random signal that is being
907 passed to the program. This produced wierd results when calling
908 functions in the inferior and signals (e.g. SIGALRM) were in use.
910 Tue Sep 24 18:05:30 1991 John Gilmore (gnu at cygnus.com)
912 * infrun.c (IN_SIGTRAMP): Not parenthesized properly.
913 Bugfix from Paul Eggert <eggert@twinsun.com>.
914 * tm-ultra3.h (IN_SIGTRAMP): Ditto.
915 * valprint.c (print_floating): Print 9 digits for IEEE floats.
918 Mon Sep 23 15:50:07 1991 John Gilmore (gnu at cygnus.com)
920 * Makefile.in: Roll VERSION to 4.1.1.
921 * source.c (line_info): Peter Schauer fixes a bug I introduced in
924 Fri Sep 20 16:10:52 1991 John Gilmore (gnu at cygnus.com)
928 * Makefile.in (VERSION): Set to 4.1.
929 * language.c (set_language_command): Print useful help message,
930 and restore the language string after giving help.
931 * valprint.c (typedef_print): Print typedef in C or M2.
932 * symtab.c (list_symbols): Use it.
933 * main.c (main): Avoid any output before (gdb) prompt when -q.
934 * language.c (set_language_command): Handle errors by restoring
935 the language string to its current state (fix from A. Beers).
936 * doc/gdbint.texinfo: Roll in information from README. Rearrange
937 "how to install" and "how to print the doc" stuff so it drops
939 * configure.in: Rename rtpc CPU to romp to match config.sub.
940 * README, WHATS.NEW, TODO: Update for gdb-4.1.
942 Fri Sep 20 17:39:14 1991 Roland H. Pesch (pesch at cygnus.com)
944 * doc/gdb.texinfo: Updates from ChangeLog. set/show write,
945 autoloading shared libs, copyright etc on GDB startup, clean up $_
946 and $__ index refs, set/show listsize and related updates to list
947 cmd. New host/target configs.
949 Fri Sep 20 15:46:00 1991 Roland H. Pesch (pesch at cygnus.com)
951 * doc/Makefile: generate aux version-no file doc/gdbVN.m4
952 from main Makefile.in version definition
953 doc/gdb.texinfo: use version recorded in doc/gdbVN.m4 for current
955 Makefile.in (setup-to-dist): generate doc/gdbVN.m4
957 * doc/gdb.texinfo: merge new language-switching and lang-specific
960 Fri Sep 20 15:00:57 1991 Per Bothner (bothner at cygnus.com)
962 * mcheck.c: Add __ONEFILE kludge to allow compilation by non-ANSI
963 compilers (which may lack stddef.h).
965 Fri Sep 20 13:29:42 1991 John Gilmore (gnu at cygnus.com)
967 * dbxread.c (read_dbx_symtab, process_one_symbol): N_FN and
968 N_WARNING are the same except for the N_EXT bit, so just use their
969 values alone, rather than OR-ing them with N_EXT.
971 Fri Sep 20 12:27:55 1991 Stu Grossman (grossman at cygnus.com)
973 * mipsread.c (parse_lines): Deal with negative extended line
976 * c-exp.y, m2-exp.y: #define yyerrflag and yynerrs to avoid
977 global symbol conflicts.
979 Fri Sep 20 02:28:15 1991 John Gilmore (gnu at cygnus.com)
981 * .gdbinit: Move 'set complaints' to top, so it runs even in
982 case we aren't debugging GDB.
983 * language.c (_initialize_language): Fix type check and range
984 check documentation strings.
985 * utils.c (!HAVE_VPRINTF): Define vfprintf as a function, so
986 language.c can use it. (Though language.c should really not be
987 handling warnings/errors the way it does, FIXME.)
988 * symtab.c (lookup_primitive_type): const lint.
990 Bugfix from Peter Schauer:
991 * source.c (lines_to_list): Make signed, to avoid comparison
992 going unsigned and complaining that -3 is too high for 21 lines.
993 * stack.c (lines_to_list): Ditto.
995 Thu Sep 19 23:33:41 1991 John Gilmore (gnu at cygnus.com)
997 * Makefile.in (HFILES): Add minimon.h.
998 (VERSION): Roll version number to 4.0.95.
999 (gdb.tar.Z, make-proto-gdb.dir, setup-to-dist, gdb-XXX.tar.Z):
1000 New rules for building distributions. Normal distribution
1001 is built by doing `make -f Makefile.in gdb.tar.Z' in the directory
1002 one level up from here; it calls make-proto-gdb.dir to build a
1003 directory `proto-gdb' which is an image of the release. The old
1004 `gdb.tar.Z' rule still works too.
1005 * config.sub, configure: Roll in latest from ..
1007 Thu Sep 19 17:41:24 1991 Roland H. Pesch (pesch at cygnus.com)
1009 * doc/gdbint.texinfo: Reorder contents; reorganize new-host,
1010 new-target, and new-config chapters; fix minor typos; come closer
1011 to usual GNU markup conventions for @file @samp @code @var.
1013 Thu Sep 19 17:04:12 1991 Per Bothner (bothner at cygnus.com)
1015 Patches from Peter Schauer <pes@regent.e-technik.tu-muenchen.de>:
1016 * mipsread.c (parse_partial_symbols): Enter the name of all
1017 structs/unions... into the psymtab so we can access them if the
1018 symtab is not read in.
1019 * mips-tdep.c: Remove some unneeded #includes.
1020 * xconfig/dec3100: Add HAVE_STRSTR.
1022 Thu Sep 19 15:14:23 1991 John Gilmore (gnu at cygnus.com)
1024 * Makefile.in: Circumvent Sun Make bug on *-exp.tab.o.
1025 * c-exp.y, m2-exp.y: Lint.
1026 * m2-exp.y: Avoid using yytname[] which is a Bison-ism.
1027 * valprint.c (val_print_fields): Check for stub type.
1028 * mipsread.c (_initialize_mipsread): Avoid using
1029 builtin_type_void at initialize time.
1030 (mipscoff_symfile_read): use it now.
1032 Wed Sep 18 15:55:51 1991 John Gilmore (gnu at cygnus.com)
1034 Merge multiple-language support, and partial Modula-2 support,
1035 from Andrew Beers <beers@cs.buffalo.edu>.
1037 * i387-tdep.c: New file, consolidates most 80387 support,

1057 (process_coff_symbol): #if 0'd for functions and params as above.
1058 (read_enum_type): Recognize Modula-2 BOOLEAN.
1059 * symtab.c (add_param_to_type): #if 0'd function to add a

1131 Tue Sep 17 08:37:41 1991 John Gilmore (gnu at cygint.cygnus.com)
1133 Add Andrew Beers' changes for Modula-2 support. His ChangeLog
1134 entries are enclosed herein. Not all of these changes
1135 have been merged into the master GDB sources -- check the
1136 ChangeLog above here for the merge log.
1138 Mon Jun 3 17:05:45 EDT 1991
1140 m2-exp.y Created. Tested outside of GDB for a few days. Proper
1141 operators were added, C specific operators and tokens
1142 removed. yylex() revamped to some extent. Still things
1143 missing from the grammar, such as sets.
1144 Tested for two weeks in GDB v3.5.
1146 Tue Jun 11 17:23:48 EDT 1991
1148 m2-exp.y Added boolean constants TRUE and FALSE to the grammar
1149 so they are built-in. Sort of a hack.
1151 Fri Jun 14 12:53:51 EDT 1991
1153 m2-exp.y Added range checking for numeric constants. Any numeric
1154 constant is assumed to be of builtin type INTEGER unless:
1155 (1) it is octal or hexadecimal, in which case it is a
1156 CARDINAL; (2) it is too big to fit into an INTEGER, in
1157 which case it is a CARDINAL.
1158 eval.c Added simple range checking for +, -, and * on integers.
1159 Doesn't work very well for *, since 6 * 1,000,000,000 =
1160 1,705,032,704, which fails the simple test of result >=
1161 first_operand, no matter in what order the operands are.
1163 Tue Jun 18 14:11:30 EDT 1991
1165 Broke the parser into parts, one containing the C grammar and the other
1166 containing code to be shared by all of the grammars.
1168 The following files no longer exist:
1173 The following files were added:
1175 c-exp.y (The C grammar)
1176 m2-exp.y (The Modula-2 grammar)
1177 parser-code.c (Code that is shared by the above grammar)
1181 Makefile.dist Changed to reflect the above dependencies. NOTE: It is
1182 now necessary to use the Bison compiler compiler, since it
1183 will generate function/variable prefixes other than yy.
1185 Tue Jun 18 16:47:49 EDT 1991
1187 symtab.[ch] Added the external variable working_lang, than holds the
1188 value of the current working language.
1189 Added the ennumerated type language_mode, with the values
1190 language_auto and language_manual, the former meaning that
1191 GDB sets working_lang as needed, and the latter meaning
1192 that the value of working_lang is totally under user
1194 symtab.[ch] Added the Modula-2 pervasive types INTEGER, CARDINAL,
1195 REAL, BOOLEAN and CHAR. Also added the type codes
1196 TYPE_CODE_BOOL and TYPE_CODE_CHAR.
1197 utils.c Added set_language_command and show_language_command to
1198 implement the GDB support commands "set language" and
1200 expression.h A number of identifiers were added to the type exp_opcode
1201 to facilitate Modula-2 builtin functions, integer
1202 division, and array indexing.
1204 Wed Jun 19 13:25:58 EDT 1991
1206 language.h Added the macro STRICT_TYPE, which evaluates to non-zero
1207 if the language specified by working_lang requires the use
1208 of strict typing of expressions. Eventually, even this
1209 will be able to be changed by the user.
1210 Added the macro RANGE_CHECK, which evaluates to non-zero
1211 if the language specified by working_lang requires the
1212 checking of a value against the domain of its type.
1213 Eventually, even this will be able to be changed by the
1215 language.[ch] Predicates involving types (simple_type, ordered_type,
1216 same_type, integral_type, numeric_type, character_type,
1217 boolean_type, float_type) are added. These predicates are
1218 based on the current value of working_lang, and are handy
1221 Wed Jun 19 15:39:34 EDT 1991
1223 eval.c Added the function type_array_rank which computes the rank
1225 valarith.c Added the funtion value_bool, which when given a integer
1226 value.h value (ie. struct value *) as an argument, it returns a
1227 boolean value (ie. struct value *) true if that integer
1228 is non-zero, and a boolean value false otherwise.
1229 valprint.c Added cases for TYPE_CODE_BOOL, so Modula-2 BOOLEAN values
1230 will print out properly.
1232 Wed Jun 19 16:36:34 EDT 1991
1234 valops.c Added the function value_capitalize, which returns it
1235 value.h argument capitalized if its argument is a lowercase
1236 letter, or the argument unchanged if its argument is not a
1238 valarith.c Added the function range_check_p, which returns non-zero
1239 value.h if its value argument is between the integral bounds upper
1241 Added the function range_check_enum_p, which makes sure
1242 that its value argument is a valid member of the domain of
1244 Added the function range_check_range_p, which makes sure
1245 its value argument lies between the upper and lower bounds
1246 of its type argument, which must be a ranged type.
1247 Added the function check_array_index, which range and type
1248 checks an index of an array.
1249 Added the function value_multi_subscript, which computes
1250 array[idx1,idx2...idxN], given a value array and an array
1251 of values representing indicies.
1252 values.c Changed value_from_long to work with TYPE_CODE_CHAR and
1253 unpack_long to work with TYPE_CODE_BOOL and
1256 Wed Jun 19 18:04:08 EDT 1991
1258 symtab.c Stored pervasive types in a structure and make
1259 lookup_pervasive_type() a lookup function that was based
1260 on working_lang. If lookup_pervasive_type() returned
1261 non-zero, then that value was returned (a fix, since
1262 before it simply wouldn't return the pervasive type.)
1263 language.h Added the macro CAST_IS_CONVERSION, which evaluates to
1264 non-zero if the language specified by working_lang means
1265 "conversion" when it says "cast".
1266 valops.c Added the function value_real_cast(), which performs a
1267 value.h *cast*, not a *conversion*, which is what value_cast()
1268 does when it can. In particular,
1269 value_cast(<float_type>,4) = 4.0, while
1270 value_real_cast(<float_type>,4) = some mess.
1271 eval.c Modula-2 builtin functions implemented: ABS, CAP, CHR,
1272 parser-code.c FLOAT, HIGH, MAX, MIN, ODD, ORD, TRUNC, and VAL.
1273 expression.h Added macros MAX_OF_TYPE and MIN_OF_TYPE to work with MAX
1274 and MIN on integral types. *NOTE*: These are currently
1275 hardcoded to work only if there are 8 bits per storage
1277 eval.c Made logical functions call value_bool to return a
1278 properly typed boolean value, based on working_lang.
1280 Thu Jun 20 11:55:27 EDT 1991
1282 valprint.c Types now print out in a Modula-2 fashion. This works for
1283 the cases when the type is printed out step-by-step, that
1284 is, it doesn't work when the name of a structured type
1285 (which includes the keyword "struct", etc.) is simply
1287 FIXME: Perhaps this is bad. Parts of it seem to kludgey,
1288 since type specifications in C and Modula-2 are very
1289 different. The C printing of a type is very recursive,
1290 whereas in Modula-2 it is generally very simple. C has
1291 type prefixes and suffixes, which have no real analogue in
1292 Modula-2. Maybe type_print() should call a language
1293 specific type printer. This is also advantageous if we
1294 compile GDB to exclude some of the languages. We'll just
1295 leave those functions out.
1297 Thu Jun 20 16:57:10 EDT 1991
1299 dbxread.c When reading the complete symbol table in (via
1300 psymtab_to_symtab()), the number and types of function
1301 arguments are added to a function type. define_symbol()
1302 calls add_param_to_type() to accomplish this.
1303 Assumption: when we come across a function definition
1304 (N_FUN symbol with an 'f' or 'F' in the name), its
1305 arguments will appear before another function definition.
1306 When a function is found, a pointer to its type is placed
1307 in the global in_function_type. Changes that
1308 add_param_to_type() makes are to this global.
1309 valprint.c The type of a function now includes (for Modula-2) the
1310 types of its parameters.
1311 eval.c Type checking and a check for the proper number of
1312 arguments is now done for function calls. Not sure of the
1313 impact this has on C++ member function yet.
1315 Thu Jun 20 19:58:48 EDT 1991
1317 valprint.c Rewrote the type printer. Broke it into two language
1318 specific parts, adding the functions type_print_m2() and
1320 An unfortunate consequence is this: if you debugging a C
1321 program in Modula-2 mode (why?), info types does not work
1322 well with regular expressions, since the types are printed
1323 out in Modula-2 terminology, but stored in C terminology.
1324 language.[ch] Added the functions new_type_last(), type_keyword(), and
1325 type_sep() to aid in the printing of typedefs.
1326 symtab.c Made the printing of typedefs as language independent as
1327 possible through calls to new_type_last(), type_keyword(),
1330 Fri Jun 21 11:50:26 EDT 1991
1332 dbxread.c Check all incoming ennumerated types. If it looks like
1333 Modula-2's BOOLEAN type, then change the type_code of the
1334 type to TYPE_CODE_BOOL so we can process it as a boolean
1336 valprint.c Replaced some of the 0x%x with calls to sprintf and
1337 hexformat() in val_print().
1338 language.[ch] Added the function hex_to_string(), which converts its
1339 integral argument to a hexadecimal number (format is
1340 language based) and returns the result as a string.
1342 Mon Jun 24 12:25:07 EDT 1991
1344 valprint.c Some functions call type_print_1() directly, instead of
1345 value.h using type_print(), so they can specify where (column) to
1346 print things. Since type_print() takes care of language
1347 dependence, that needs to be called first. Added a
1348 parameter depth to type_print() (so it is now like
1349 type_print_1). Changed type_print to type_print_at, and
1350 made type_print a macro that passes a depth argument of
1352 symmisc.c Changed all calls to type_print_1 to calls to
1354 Makefile.dist Made it possible to build GDB for a specific set of
1355 depend languages. Do this by passing a definition for the macro
1356 LANGS to make. LANGS should be a string containing a
1357 space-separated list of language names (ie. LANGS="c m2").
1358 The default is to build all languages. Note that grammar
1359 files must follow the naming convention of <lang>-exp.y.
1360 gdb.lang This holds the current value of the LANGS macro. It is
1361 examined every time make is called, and is updated if
1363 eval.c Added #ifdef _LANG_<lang> to these files.
1364 expread.c Still need to add them to dbxread.c and coffread.c.
1372 Mon Jun 24 16:33:11 EDT 1991
1374 language.[ch] Added the functions hexformat_pre() and
1375 hex_to_string_pre(), which take a prefix argument to
1376 include in the format string. Thus, hexformat_pre("08") will
1377 return "0x08x" (if the working language is language_c).
1378 Made hexformat() and hex_to_string() calls to the above
1379 with "" as the prefix argument.
1381 am29k-pinsn.c, arm-pinsn.c, breakpoint.c, convex-tdep.c, exec.c, core.c,
1382 dbxread.c, i386-pinsn.c, i386-stub.c, i386-xdep.c, i960-pinsn.c,
1383 infcmd.c, inflow.c, m68k-pinsn.c, m68k-stub.c, m88k-pinsn.c,
1384 mips-pinsn.c, mips-tdep.c, ns32k-pinsn.c, printcmd.c, pyr-pinsn.c,
1385 pyr-tdep.c, pyr-xdep.c, remote-vx.c, remote.c, solib.c, source.c,
1386 stack.c, sun386-xdep.c, symfile.c, symm-xdep.c, symmisc.c, tahoe-pinsn.c,
1387 valprint.c, vax-pinsn.c
1389 Changed all occurences of 0x%[0-9]*l*x in printf format strings to
1390 calls to hexformat() and hex_to_string(). Format strings without
1391 the leading "0x" were ignored.
1393 depend Updated to take the above into account.
1396 Tue Jun 25 15:27:18 EDT 1991
1398 symtab.h Added the types range_mode_t, range_check_t, type_mode_t,
1399 and type_check_t to keep track of the current state of
1400 range and type checking.
1401 main.c Added the variables range_mode, range_check, type_mode,
1402 and type_check to record the current state of range and
1403 type checking. Added initialization code to main().
1404 language.h Changed the macros STRICT_TYPE and RANGE_CHECK to examine
1405 the above variables.
1408 Tue Jun 25 17:57:08 EDT 1991
1410 dbxread.c process_one_symbol() updates the variable (enum language)
1411 source_lang based on the extension of the filename
1412 contained in the N_SO sybmol that started this symtab.
1413 When end_symtab() is called, the value of source_lang is
1414 put into the language field.
1415 stack.c select_frame() sets working_lang (and possibly type_check
1416 and range_check) to the language field of the symtab
1417 associated with the frame that is selected if working_mode
1418 is language_auto. If working_mode is language_manual, a
1419 warning is printed and working_lang is not set.
1420 language.c Added the function set_type_range(), which sets the value of
1421 type_check and range_check (if their modes call for
1422 automatic setting) based on the current value of
1423 working_lang. A non-zero argument will cause the current
1424 settings to be output.
1427 Wed Jun 26 14:51:40 EDT 1991
1429 eval.c Added range checks on assignment.
1430 m2-exp.y Added the grammar for sets to the language. Currently,
1431 these do not do anything except print an error message.
1433 Wed Jun 26 17:01:04 EDT 1991
1435 m2-exp.y Added the ability for parse_number() to parse negative
1436 numbers. A global flag is set upon encountering a unary
1437 minus. This was done to make, for example, 1 parse as a
1438 CARDINAL, and not as an integer, per Wirth's examples in
1439 Programming in Modula-2 ed.4.
1440 valprint.c Added support for "set radix 2" by then setting
1441 output_format to 't'.
1442 eval.c Implemented range checking on subrange types. Added calls
1443 to range_check_range_p for BINOP_ASSIGN and BINOP_VAL.
1444 Implemented MIN and MAX for ennumerated types. The
1445 minimum value of an ennumerated type is defined by Wirth
1446 as the first identifier, and the maximum as the last.
1447 m2-exp.y Made octal numbers ending with "B" be characters and those
1448 ending with "C" be numbers, per Wirth's book. (p. 34)
1450 Thu Jun 27 14:11:52 EDT 1991
1452 stack.c select_frame() now only sets working_lang, it does not
1453 notify the user. If working_mode is language_manual, then
1454 a warning is issued once.
1455 main.c At the end of each call to execute_command(), working_lang
1456 is checked against the local static (enum language)
1457 current. If they differ and working_mode is
1458 language_auto, the new settings of language, type and
1459 range checking are printed out.
1460 stack.c Modified frame_info() to include the language of the
1461 current frame in the output of "info frame".
1462 language.[ch] Added the function language_str() which returns the name
1463 of the current language.
1465 Fri Jun 28 15:33:14 EDT 1991
1467 m2-exp.y Added the built-in procedures INC, INCL, DEC, and DECL to
1468 the language. INCL and DECL currently cause an error,
1469 since sets are not implemented yet. INC and DEC are
1470 implemented as PREINCREMENT/PREDECREMENT with one
1471 argument, and as ASSIGN_MODIFY with two arguments.
1472 eval.c Added type checking to the above cases.
1473 value.h Added not_lval_constant to the lval_type ennumerated type.
1474 not_lval_constant means that the value is a constant
1475 value; that is 3 or 'a' or TRUE, not as in a constant
1476 identifier. This is used to help coerce numbers such as 3
1477 to either signed or unsigned numbers.
1478 valops.c Added the function value_coerce_constants() which coerces
1479 constant integers as following: if one is a constant and
1480 the other is not, the constant's type is set to the type
1481 of the other argument. If both are constants and one is
1482 signed, the other is converted to a signed constant.
1484 Sat Jun 29 17:26:29 EDT 1991
1486 valarith.c Added a better range checker. It now checks range
1487 (successfully) on integral operations [+-] (signed and
1488 unsigned) for any C sized type. Still does not work well
1489 for multiplication.)
1490 int_in_size() returns an integer that is coerced to fit into
1491 specified number of bytes.
1493 Mon Jul 1 13:04:14 EDT 1991
1495 language.[ch] Added the function binop_result_type(), which returns the
1496 builtin (struct type *) type that would be the result of a
1497 binop on the two values V1 and V2.
1499 Wed Jul 3 19:22:53 EDT 1991
1501 source.c Extended source_info() to include the source language in
1502 the output from "info source".
1504 Fri Jul 5 13:48:52 EDT 1991
1506 utils.c Moved the support functions for the GDB set/show commands
1507 dealing with language into language.c.
1508 language.c Added the function language_info(), which displays info
1509 about the current working language, type and range check
1510 settings. Called via the GDB command "info language".
1511 Added an initialization routine _initialize_language(),
1512 that sets defaults for the language, type and range
1513 variables and sets up the new GDB commands.
1514 main.c Language setup moved to language.c.
1517 Mon Jul 8 10:10:22 EDT 1991
1519 valarith.c Debugged the range checker for arithmetic. Still does not
1520 work for multiplication very well.
1522 Mon Jul 8 12:40:37 EDT 1991
1524 language.[ch] Added the function value_true() which returns non-zero if
1525 its argument represents a boolean true value.
1526 breakpoint.c Changed breakpoint_cond_eval() to call value_true() to
1527 check the truth of an expression.
1529 Thu Jul 11 12:51:34 EDT 1991
1531 language.[ch] Added the predicate structured_type(), which returns
1532 non-zero if the argument is a structured type.
1533 Added the predicate pointer_type(), which returns non-zero
1534 if the argument is a pointer type.
1535 eval.c Added the ability to do addition and substraction on
1536 pointers and integers. This case simply bypasses the
1539 Thu Jul 11 14:41:42 EDT 1991
1542 Added the symbol N_DEFD (0x4a) which is a definition
1543 module dependency that is used by the GNU Modula-2
1544 compiler and the linker. It is not important to GDB,
1545 except that [dbx|coff|mips]read.c should ignore these
1548 Fri Jul 12 16:07:00 EDT 1991
1550 valprint.c Changed the TYPE_LENGTH(type) >= 0 to TYPE_LENGTH(type) >
1551 0 in val_print(). Also added statements to the else part
1552 to coerce type (argument to val_print) to a pointer type
1553 if it is an "array of unspecified length".
1554 valops.c Added the function value_m2_string(), which returns a
1555 (value) value which is a constant string, whose type is
1556 (ARRAY [0..n] OF CHAR). The length field of the type
1557 structure is set to zero, so it will be interpreted as an
1558 "array of unspecified length".
1559 stack.c Moved the language/frame mismatch check to
1560 main.c:execute_command().
1561 main.c The working language is recorded each time
1562 execute_command() is executed. If working lang has
1563 changed during its execution, then the new
1564 language/type/range info is printed out for the user. If
1565 the working language does not match the language of the
1566 frame, a warning is issued.
1568 Sat Jul 13 16:16:39 EDT 1991
1570 eval.c Moved all the type-checking stuff for operators to
1571 language.[ch] language.c. This is so we can keep language-specific
1572 stuff (like for what type operators are defined) in
1574 language.[ch] Added the function binop_type_check(), which checks to see
1575 if its two (value) arguments are type-compatible with its
1576 opcode argument. The opcode should represent an operation
1577 involving an operator. Also added the macro function
1578 unop_type_check, which calls binop_type_check with a
1579 NULL second argument.
1580 expprint.c Added Modula-2 operators to the op_print_tab, so info
1581 expression.h break works correctly. Also added "op_string", which
1582 returns the string corresponding to the (enum exp_opcode)
1583 opcode that is its argument.
1586 Sat Jul 13 18:26:18 EDT 1991
1588 coffread.c Added code to record the type of function arguments with
1589 each paricular function. Code is very similar to that
1591 dbxread.c Moved add_param_to_type() to symtab.c
1592 symtab.[ch] Added function add_param_to_type() from dbxread.c
1594 *** NOTE: The above additions have not been tested.
1596 Mon Jul 15 12:50:47 EDT 1991
1598 langauge.[ch] Added the functions type_error and range_error, which work
1599 like error() except if the type/range mode is set to
1600 *_mode_warn, then they do not do a return_to_top_level(),
1601 but merely print a warning.
1602 Also changed [set|show]_[type|range]_command() to support
1603 the new "warn" feature.
1605 Thu Jul 18 17:50:54 EDT 1991
1607 mipsread.c Added code to record the type of function arguments with
1608 each particular function. Code is very similar to that
1611 *** NOTE: The above additions have not been tested.
1613 Fri Jul 19 11:19:10 EDT 1991
1615 defs.h Added macros MAX_OF_SIZE, MIN_OF_SIZE, UMAX_OF_SIZE, and
1616 UMIN_OF_SIZE, which when given a size of a numeric type,
1617 return the maximum and minimum value it can hold. UMAX...
1618 and UMIN... return the result for unsigned types.
1619 symtab.h Added the macros MAX_OF_TYPE and MIN_OF_TYPE to operate on
1620 struct types. They call above macros.
1621 dbxread.c Renamed the MAX and MIN_OF_TYPE macros to ..._OF_CTYPE to
1622 avoid a name conlict with the above.
1623 c-exp.y Added range checking on numeric constants in
1624 parse_number() for completeness.
1625 valarith.c Made binop_user_defined_p() and unop_user_defined_p()
1626 return 0 if working_lang is not language_c.
1628 Thu Aug 8 14:17:22 EDT 1991
1632 breakpoint.c Documentation strings of some commands changed to
1633 eliminate the references to the C language where
1636 Tue Aug 13 15:48:03 EDT 1991
1638 m2-exp.y Added qualified identifiers to the grammar. The semantics
1639 are slightly different from those of the GDB operator ::
1641 m2-exp.y Added a rule to each grammar of the form: start ::= exp |
1642 type_exp, where type_exp is any valid type expression.
1644 eval.c Added the opcode OP_TYPE, and an error case in eval.c.
1645 printcmd.c Modified ptype_command() so it actually parses the input
1646 (necessary for type expressions with scope qualifiers).
1647 Added the function ptype_eval() which expects an
1648 expression composed of one OP_TYPE element.
1649 *.[ch] Replaced all occurences of parse_c_expression with
1651 *.[ch] Replaced all occurences of parse_c_1 with parse_exp_1
1653 [End of ChangeLog entries from Andrew Beers for Modula-2 support.]
1655 Mon Sep 16 17:19:46 1991 John Gilmore (gnu at cygnus.com)
1657 Small fixes from Peter Schauer:
1659 * infrun.c (child_attach): Lint.
1660 * solib.c (find_solib): Handle shared libs version 2.
1662 Small fixes from David Wood:
1664 * xm-ultra3.h (SYS_SIGLIST_MISSING): Typo.
1668 * remote-vx.c: Move <stdio.h> to top, for FILE. Fix from
1669 John S <basrai%kanga.dnet@c3po.sm-alc.af.mil>.
1671 * utils.c (wrap_here): Avoid wrap action of fputs_filtered if
1672 chars_per_line is at maximum (user typed `set width 0'). Fix
1673 from Andreas Schwab <schwab@ls5.informatik.uni-dortmund.de>.
1675 Tue Sep 17 17:31:04 1991 Stu Grossman (grossman at cygnus.com)
1677 * coredep.c: include ptrace.h where necessary.
1678 * mipsread.c(parse_lines): fix unsigned char problem that was
1679 messing up line numbers on SGI's and possibly other MIPS based
1681 * infrun.c (child_create_inferior): use better test to check
1682 return val from setpgrp().
1683 * tm-irix3.h, xm-irix3.h, tconfig/irix3, xconfig/irix3: add these
1684 for sgi/irix support.
1686 Wed Sep 18 04:33:31 1991 Per Bothner (bothner at cygnus.com)
1688 * mipsread.c (parse_symbol): Put non-static procedures
1689 in the global block.
1691 Fri Sep 13 00:14:52 1991 John Gilmore (gnu at cygnus.com)
1693 Patch together `text_start' and `text_end' for 29K port.
1695 * exec.c (exec_command): If NEED_TEXT_START_END, define the
1696 variables and set them based on the exec file.
1697 * am29k-tdep.c: declare text_start.
1698 * valops.c (call_function_by_hand): declare text_end.
1700 * inferior.h: Eliminate CANNOT_EXECUTE_STACK in favor of
1701 defining CALL_DUMMY_LOCATION as BEFORE_TEXT_END. This is
1702 because machines that do this will also have to know to
1703 set NEED_TEXT_START_END. Besides, it was a redundant way to
1705 * tm-29k.h, tm-convex.h, tm-np1.h: Eliminate
1706 CANNOT_EXECUTE_STACK, define CALL_DUMMY_LOCATION and
1707 NEED_TEXT_START_END.
1709 Thu Sep 12 00:22:24 1991 John Gilmore (gnu at cygint.cygnus.com)
1711 AMD 29000 changes from David Wood <wood@david.ultra.nyu.edu>:
1713 * Makefile.in (CLIBS): Put XM_CLIBS and TM_CLIBS at end.
1714 Pass MUNCH_DEFINE to munch whenever we run it.
1715 * am29k-pinsn.c (print_insn): Handle NOP specially. Avoid %#x
1716 format string; use 0x%x instead.
1717 * am29k-tdep.c: Use DUMMY_SAVE_GREGS and RETURN_REGNUM.
1718 * ultra-xdep.c, xm-ultra.h: New files for Ultracomputer host system.
1719 * xm-rtbsd.h: New host support for RT/PC running BSD Unix.
1720 * inflow.c: Handle `short' process group IDs.
1721 * infptrace.c (fetch_register): Support CANNOT_FETCH_REGISTER,
1722 and check for ptrace errors.
1723 * coffread.c (SDB_REG_TO_REGNUM): Define if not already.
1724 (coff_symfile_init): Initialize text_bfd_scnum.
1725 (read_coff_symtab): Use it to find the text [and absolute?] sections.
1726 * ../config.sub: Add vendor nyu and os "sym[1-9]*".
1727 * configure.in: Add hosts rtpc-*-* and a29k-*-*.
1728 Merge target arm case with other "easy" cases. Add target
1729 cases a29k-*-none (rehack of am29k), a29k-*-kern (remote to
1730 Ultracomputer kernel), and a29k-*-sym1 (ultracomputer OS's user
1732 * minimon.h, remote-adapt.c, remote-mm.c: Add.
1733 * munch: Cope with RT/PC putting fns in data segment.
1734 Restore ability to override `nm' by specifying MUNCH_NM.
1735 * xconfig/rtbsd, xconfig/ultra3: New host systems.
1736 * tconfig/a29k: Rename from tconfig/am29k. Add remote-mm
1737 and remote-adapt. Remove encapsulated coff #define's (the
1738 support should go in BFD, and gdb shouldn't know or care).
1739 * tconfig/a29k-kern: Same, but for remote kernel debugging.
1740 * tconfig/ultra3: For debugging user processes on Ultra3/Sym1.
1741 * tm-29k.h: Update BADMAG (though it should go away).
1742 Allow the register definitions to be overridden in another
1743 tm-file. Fix SR_REGNUM. Add a mess of _REGNUM's. Separate
1744 RETURN_REGNUM from GR96_REGNUM and DUMMY_SAVE_GREGS from
1745 DUMMY_SAVE_GR96, for handling kernel calling conventions
1746 that use GR64+ rather than GR96+.
1747 * tm-ultra3.h: New file, for use on Ultra3 Unix as well as for
1748 remote debugging of Ultra3 kernel. Includes tm-29k.h and
1749 overrides various things.
1751 * remote-mm.c (mm_attach, mm_wait): Handle attach like
1752 child_attach does, making a clean stop in the newly attached
1754 * remote-eb.c: Lint.
1756 * coffread.c: Make coffread independent of any particular
1757 variant of COFF. Avoid #include-ing any particular one except
1758 internalcoff.h. BFD now passes key values for symbol reading
1759 as part of its coff_data structure (LINESZ, SYMESZ, AUXESZ,
1760 and the symbol masks and shifts); use them.
1761 Remove obsolete end_of_text_addr.
1763 * exec.c: Remove unused include files.
1765 Wed Sep 11 19:38:44 1991 John Gilmore (gnu at cygint.cygnus.com)
1767 * Makefile.in (documentation targets): Pass $(M4).
1768 Bugfix from eggert@twinsun.com (Paul Eggert).
1770 * stack.c (down_silently_command): Check for stack existence.
1772 Tue Sep 10 23:08:29 1991 John Gilmore (gnu at cygint.cygnus.com)
1774 * Makefile.in (VERSION): Update to 4.0.3.
1776 Tue Sep 10 09:19:29 1991 John Gilmore (gnu at cygint.cygnus.com)
1778 * core.c (core_file_command): Print frame at coredump with
1779 its level number, by calling print_stack_frame.
1780 * frame.h: Add selected_frame_level, print_stack_frame.
1781 * frame.h, stack.c: Remove print_sel_frame, print_selected_frame.
1782 * convex-tdep.c, convex-xdep.c, infcmd.c, inflow.c, infrun.c:
1783 Change print_sel_frame and print_selected_frame callers to
1786 * dbxread.c (read_ofile_symtab): Avoid empty else clause.
1787 * symfile.c (free_named_symtabs): Ditto.
1788 * main.c (main): wrap_here needs an arg.
1789 * solib.c (find_solib): Avoid memory access if _DYNAMIC is zero.
1790 (solib_add): Avoid noise.
1791 (solib_create_inferior_hook): Lint.
1792 (sharedlibrary_command): Move dont_repeat to here.
1793 * utils.c (error): Call wrap_here to force buffered output.
1795 Small patches from Peter Schauer:
1797 * coffread.c (start_symtab): Free any existing line_vector before
1799 (read_coff_symtab): Ditto for type_vector.
1801 * source.c (lines_to_list): New variable, replacing function.
1802 (all uses): Use as variable.
1803 (_initialize_source): Add 'set listsize' and 'show listsize'.
1804 * utils.c (lines_to_list): Remove function.
1805 * stack.c (print_frame_info): Use as variable.
1806 * defs.h (lines_to_list): Remove declaration.
1808 Mon Sep 9 13:45:57 1991 John Gilmore (gnu at cygint.cygnus.com)
1810 * breakpoint.c (insert_breakpoints): Restore warning about
1811 the program might be running in another process, but only for
1812 systems with this brain death (#ifdef ONE_PROCESS_WRITETEXT).
1813 * xm-hp300bsd.h, xm-mips.h, xm-vax.h: Define it.
1815 * utils.c (error): if error_pre_print is set, print the string
1817 * main.c (main, print_gnu_advertisement, print_gdb_version):
1818 Reformat legalese so it always prints, but acts as an "I'm here"
1819 message while symbols are being read. If any errors occur,
1820 print a few newlines to set off the message and start it at the
1821 left margin. Remove mention of "help" command, and don't yak
1822 about symbol reading.
1823 (catch_errors): Error string is now printed first in case of
1825 * command.c (undef_cmd_error, lookup_cmd): On undefined command,
1826 suggest the "help" command.
1828 * Makefile.in (VERSION): Set to 4.0.2.
1830 Thu Sep 5 23:49:48 1991 John Gilmore (gnu at cygint.cygnus.com)
1832 * .gdbinit: Remove useless "rr" command. Set complaints
1833 to 1 for people debugging gdb.
1835 * breakpoint.c, remote-vx.c: Reword strings printed by
1836 catch_errors callers.
1838 Wed Sep 4 11:07:50 1991 John Gilmore (gnu at cygint.cygnus.com)
1840 * WHATS.NEW: "history write -> history save". Doc "write on/off".
1841 (Fix from kenc@viewlogic.com.)
1843 Fix some infrastructure to be able to cope with host and target
1844 machines with different sized basic types (ints, ptrs, etc).
1845 (Idea from pierre@la.tce.com (Pierre Willard).)
1847 * values.c (value_from_longest): Rename from value_from_long.
1848 Handle pointer types as well as integers, so that targets with
1849 different pointer sizes from the host can be accomodated.
1850 * breakpoint.c, convex-tdep.c, eval.c, expprint.c, printcmd.c,
1851 valarith.c, valops.c, valprint.c, value.h, values.c: Rename
1852 uses of value_from_long to value_from_longest.
1853 * eval.c, findvar.c, printcmd.c, valarith.c, valops.c: Pass
1854 the correct pointer type to value_from_long{est}.
1856 * doc/gdb.texinfo ($_, $__): Describe types of these variables.
1858 * remote-vx.c: Remove obsolete code for calling functions via
1859 vxworks kludge interface (it referenced value_from_long).
1861 * valops.c (value_string): Find malloc with lookup_misc_func, not
1864 Tue Sep 3 18:37:46 1991 John Gilmore (gnu at cygint.cygnus.com)
1866 Make writing to files work properly. (Fixes to BFD are also needed.)
1868 * core.c (core_open): Open file ourselves, read or r/w, depending on
1869 write_files. Use bfd_fdopenr.
1870 * gdbcore.h (write_files): New variable.
1871 * exec.c (write_files): Define variable, add set&show for it.
1872 (exec_file_command): Use write_files to open for read or r/write.
1874 Make shared library reading happen automatically. These changes
1875 are mostly from Peter Schauer <pes@regent.e-technik.tu-muenchen.de>.
1877 * inferior.h (stop_soon_quietly): Add to exported variables.
1878 * infrun.c (child_create_inferior): call solib hook, if defined.
1879 (child_attach): call solib hook, if defined.
1880 * solib.c: Include inferior.h. Add from_tty to so_list as kludge.
1881 (find_solib): Use lookup_misc_func rather than hand-rolled.
1882 (symbol_add_stub): New stub for catch_errors.
1883 (solib_add): Avoid output if !from_tty. Catch errors rather
1884 than just calling symbol_file_add and bombing.
1885 (solib_create_inferior_hook): Interface with the target process
1886 to let it read and alloc shared libs, then figure out what it did.
1888 * core.c (validate_files): Fix typo, soften warning.
1889 (Fix from Hiroto Kagotani <kagotani@cs.titech.ac.jp>.)
1891 * utils.c (fputs_demangled): Avoid duplicate printing if
1892 demangling is off. (Fix from J.T. Conklin <jtc@cayenne.com>.)
1894 * infrun.c (proceed): Cast -1 to (CORE_ADDR) before comparing.
1895 (Fix from pierre@la.tce.com (Pierre Willard).)
1897 * main.c (catch_errors): Change argument to a char * from an int,
1898 since a char * can point to a struct full of glop, but an int
1899 is not guaranteed to be able to hold a pointer.
1900 * breakpoint.c (breakpoint_cond_eval, bpstat_stop_status,
1901 breakpoint_re_set_one, breakpoint_re_set): Adapt.
1902 * core.c (core_open, solib_add_stub): Adapt.
1903 * remote-vx.c (symbol_stub, add_symbol_stub, callers): Adapt.
1905 Wed Aug 28 18:18:05 1991 John Gilmore (gnu at cygint.cygnus.com)
1907 * Makefile.in: Update VERSION to 4.0.1. Evade GNU Make bug
1908 by adding .NOEXPORT target.
1910 Fri Aug 23 17:14:25 1991 John Gilmore (gnu at cygint.cygnus.com)
1914 * Makefile.in (VERSION): Roll to 4.0.
1915 (gdb.tar.Z): Make refcard.ps as well, for shipment.
1917 Fri Aug 23 14:07:09 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1919 * doc/gdb.texinfo: minor rewordings, crossref to ptype from print,
1922 * doc/Makefile, Makefile.in: generate "gdb-all.texi" rather than
1925 * doc/rdl-apps.texi: renamed from rdl-apps.texinfo
1927 * Makefile.in, doc/Makefile, doc/.Sanitize, doc/gdb.texinfo:
1928 reflect above name change
1930 * WHATS.NEW: correct pointer to refcard.
1932 * doc/gdb.texinfo: update New Features, Installing
1934 * doc/gdbint.texinfo: add short description of configure +template
1936 Fri Aug 23 11:46:08 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1938 * doc/gdb.texinfo: update, fix bugs in "Installing" appendix
1940 Fri Aug 23 01:02:00 1991 John Gilmore (gnu at cygint.cygnus.com)
1942 * Makefile.in: Add config.sub, make doc/rdl-apps.texinfo for
1943 tar file, add dependencies for referenced doc files.
1945 Thu Aug 22 22:17:06 1991 Stu Grossman (grossman at cygint.cygnus.com)
1947 * coffread.c, symfile.c, stack.c: saberized.
1949 Thu Aug 22 16:20:27 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1951 * doc/refcard.tex: permuted Essential Commands sec
1953 * doc/gdb.texinfo: new C++ chapter; revised installation appendix;
1955 set/show symbol-reloading
1956 default set complaints 0
1958 RET-repeat disabled after prompted long displays
1959 processID (attach) interpretation of 2nd GDB cmdline arg
1961 Thu Aug 22 14:05:47 1991 Stu Grossman (grossman at cygint.cygnus.com)
1963 * expread.y, coffread.c, dbxread.c, target.c, mem-break.c,
1964 cplus-dem.c, values.c, valprint.c, symfile.c, remote.c,
1965 breakpoint.c, main.c: lint.
1967 Thu Aug 22 02:02:26 1991 John Gilmore (gnu at cygint.cygnus.com)
1969 Install new configuration scheme for GDB and friends.
1971 * config.sub: Translate ordinary names to three-part names.
1972 * configure: Use three-part names internally.
1973 * configure.in: Translate three-part names to filenames.
1975 * README, WHATS.NEW: Update for gdb-4.0.
1976 * Makefile.in: Roll VERSION to 3.99.
1978 Wed Aug 21 18:21:09 1991 John Gilmore (gnu at cygint.cygnus.com)
1980 * infptrace.c (KERNEL_U_ADDR_BSD): Include a.out.gnu.h.
1981 * i960-tdep.c, m68k-tdep.c, sparc-tdep.c, tm-i960.h,
1982 tm-m68k.h, remote-nindy.c: Change ext_format_XXX structs
1983 to single structures rather than arrays; when passing
1984 their address, use &. This avoids trouble with bdead compilers.
1985 * mcheck.c: Don't include <stdlib.h>; just declare "void abort();"
1986 instead. This avoids portability headaches.
1987 * mips-tdep.c (mips_do_registers_info): Only print FP regs if
1989 * source.c (open_source_file): Avoid ANSI const bdeath by
1990 skipping declaration and then casting result value.
1991 * tm-hp300bsd.h: Clarify comment.
1992 * utils.c (strstr): Result is const char *; ANSI bdeath.
1993 * xm-hp300bsd.h: Define HOST_BYTE_ORDER. Redefine INT_MIN,
1994 since system include file defines it differently from "defs.h",
1995 though the two are equivalent for our purposes.
1996 * tconfig/hp300bsd: Add m68k-tdep.o.
1998 Tue Aug 20 16:01:11 1991 John Gilmore (gnu at cygint.cygnus.com)
2000 * tconfig/sun*4: Remove warnings about system assembler.
2002 Mon Aug 19 13:44:46 1991 John Gilmore (gnu at cygint.cygnus.com)
2004 * mcheck.c: Avoid warning about undeclared abort fn.
2005 * tm-sparc.h (PC_ADJUST): Avoid calling error() from this;
2006 it causes recursive calls to error() when used in cleanups.
2007 To do so requires that we make it a function, so we do.
2008 * sparc-tdep.c (sparc_pc_adjust): New implem of PC_ADJUST.
2009 * utils.c (do_cleanups): Remove the current cleanup from the
2010 chain *before* calling it, in case error() is called from it.
2011 The result won't be pretty, but won't be an infinite loop either.
2013 Mon Aug 19 00:41:04 1991 Michael Tiemann (tiemann at cygint.cygnus.com)
2015 * dbxread.c (read_struct_type): Grok anon structs for C++.
2016 (vb_name, vptr_name): Null terminate these strings.
2018 Fri Aug 16 08:31:03 1991 John Gilmore (gnu at cygint.cygnus.com)
2020 Minor bug fixes from BSD Net2 gdb:
2022 * blockframe.c (get_prev_frame_info): If FRAME_CHAIN_COMBINE
2023 returns 0, there is no previous frame.
2024 * breakpoint.c (commands_command): If !from_tty, don't call
2025 input_from_terminal_p().
2026 * dbxread.c (record_misc_function): Speed up slightly.
2027 (compare_psymbols): Ditto.
2028 * infcmd.c (do_registers_info): Take a second argument to
2029 determine whether to print float registers. "info registers"
2030 does not do so anymore. "info all-registers" does, now.
2031 * mips-tdep.c, pyr-tdep.c (xxx_do_registers_info): Take second
2033 * tm-mips.h, tm-pyr.h (DO_REGISTERS_INFO): Pass second arg.
2034 * inflow.c (initialize_inflow): Set tflags_ours correctly.
2038 * breakpoint.c (bpstat_do_actions): Use a cleanup to restore
2039 executing_breakpoint_commands if we are interrupted by error.
2040 * coffread.c (init_lineno): Avoid problem with zero-sized linetab
2041 versus malloc/free. From: john@labtam.labtam.oz.au (John Carey).
2042 * core.c (solib_add_stub, core_open): Call SOLIB_ADD inside a
2043 catch_errors() so we can setup the frame regardless of whether
2044 the shared libs work.
2045 * ieee-float.c (double_to_ieee_extended): Get exponent from
2046 right place in little-endian systems. From John Carey.
2048 Thu Aug 15 18:43:57 1991 John Gilmore (gnu at cygint.cygnus.com)
2050 * main.c: Remove unused terminating_signals and catch_termination().
2051 (long_options): Terminate with a zero element.
2052 [Bugfix from Atsuo Kawaguchi <atsuo@hark86.harl.hitachi.co.jp>.]
2053 (gdb_readline): Make call-compatible with readline.
2054 (init_signals): Improve comments re vfork vs. signal.
2056 * utils.c (prompt_for_continue): Use new gdb_readline().
2057 If we prompt for continuation, we don't let CR repeat the previous
2058 command, once we get back to a prompt. It's too easy to keep
2059 hitting CR, expecting "--more--" prompts, and have some long
2060 command start repeating on you.
2062 Tue Aug 13 16:17:56 1991 John Gilmore (gnu at cygint.cygnus.com)
2064 * blockframe.c (frameless_look_for_prologue): Speed up by
2065 calling SKIP_PROLOGUE_FRAMELESS_P if it's defined.
2066 * tm-sparc.h (SKIP_PROLOGUE, SKIP_PROLOGUE_FRAMELESS_P):
2067 Define two variants, one faster.
2068 * sparc-tdep.c (sparc_frame_chain): Use target_read_memory
2069 and return zero, rather than giving an error.
2070 (setup_arbitrary_frame): Initialize the PC in the new frame.
2071 (skip_prologue): Add a second arg saying whether we're just
2072 checking for a frameless function or not.
2074 * core.c (core_open, core_close, core_xfer_memory): Move
2075 section table pointers and bfd* into the target_ops.
2076 (core_open): Allow errors in shared lib reading, etc.
2077 (core_files_info): Describe shared library sections.
2079 * exec.c (exec_open, exec_close, exec_xfer_memory, xfer_memory,
2080 exec_files_info, set_section_command): Move section table
2081 pointers and bfd* into the target_ops.
2082 (add_to_section_table): Add BFD to section table.
2084 * target.c (target_xfer_memory, target_info): Pass target to
2085 xfer_memory and target_info functions.
2088 * gdbcore.h: Move struct section_table.
2089 * target.h: New home of struct section_table.
2091 * solib.c (solib_add): New argument is the target_ops whose
2092 section list is to be added to, if any. Reallocate the
2093 sections in that target to add any that come from shared libs.
2094 (throughout) so_sections renamed to sections.
2095 (solib_xfer_memory): Deleted.
2096 * tm-sunos.h (SOLIB_ADD): Add target argument.
2097 (SOLIB_XFER_MEMORY): Delete.
2099 * core.c, exec.c, inftarg.c, remote-eb.c, remote-nindy.c,
2100 remote-vx.c, remote.c, target.c, target.h: Remove add_syms vector
2101 from target_ops. It's the same on all targets. Add two section
2102 pointers to target_ops.
2104 * stack.c (find_relative_frame): Dump ancient algorithm for
2105 "down", just use handy "next" pointers.
2106 (frame_command): Don't error if there is no stack; let user
2109 * inflow.c (new_tty_prefork, new_tty): New prefork routine
2110 modifies static state in the parent process; new_tty itself
2111 runs in the child and modifies the child's file descriptors
2112 to match the saved static state.
2113 * infrun.c (child_create_inferior): Call new_tty_prefork,
2116 * infptrace.c (child_xfer_memory): Add ignored target arg.
2117 * remote-eb.c (eb_xfer_inferior_memory): ''
2118 * remote-nindy.c (nindy_xfer_inferior_memory): ''
2119 * remote-vx.c (vx_xfer_memory): ''
2120 * remote.c (remote_xfer_memory): ''. Rename from
2121 remote_xfer_inferior_memory.
2123 * main.c (main): Only try to attach "corefile" argument if
2124 it starts with a digit.
2126 * symfile.c (symbol_reloading): New "set/show" variable.
2127 (symbol_file_add): Shorten message about symbol reading.
2128 (add_symbol_file_command): Merge with add_syms_addr_command,
2129 since this should work on all targets now.
2130 (stop_whining): Default to zero, to shut up complaints
2131 about bad symbol tables on many systems.
2132 (free_named_symtabs): Just exit unless symbol_reloading.
2134 * xm-sun3os4.h, xm-sun4os4.h: Define BROKEN_LARGE_ALLOCA,
2135 and add comment explaining shared library screw.
2137 * source.c: #if defined => #ifdef.
2139 Thu Aug 8 12:23:19 1991 John Gilmore (gnu at cygint.cygnus.com)
2141 * doc/gdbint.texinfo: Improve doc on porting to new OS's.
2143 Tue Aug 6 17:16:15 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
2145 * doc/rdl-apps.texinfo: provide default readline-appendix finder
2146 (doc/Makefile knows how to make one for local config)
2148 * Makefile.in: use doc/Makefile for doc targets
2150 * doc/Makefile: GDB documentation now has its own Makefile
2151 doc/refcard.tex: renamed from "gdbrc.tex"
2152 doc/.Sanitize: add Makefile; recognize renamed refcard.tex
2153 doc/gdbint.texinfo: add markup in "Cleanups" chapter
2156 Fri Aug 2 00:13:06 1991 John Gilmore (gnu at cygint.cygnus.com)
2158 * values.c (baseclass_addr): When reading target memory, use the
2159 length of the basetype, not the upper type. We've only malloc'd
2160 enough space for the basetype, leading to errors in free().
2162 * expprint.c (print_subexp): Print UNOP_MEMVAL of an OP_LONG that
2163 ends up as a function specially, since we know the actual type of
2164 the pointed-to address. This (somewhat) fixes display of
2165 expressions that include misc_function_vector names. Try `cond 1
2166 !strcmp("a","b")' then `i b'.
2168 * infrun.c: Move DO_DEFERRED_STORES from proceed() to resume().
2169 The child can be proceeded from inside wait_for_inferior in
2170 evaluating breakpoint conditions, and DO_DEFERRED_STORES was
2171 getting skipped in that case.
2173 * expprint.c (print_subexp): Use filtered output, since the
2174 subroutines we call use it, otherwise the output is horribly
2175 mangled, since output of wrappable stuff comes out late.
2177 * Makefile.in: Bump VERSION to 3.98.1
2179 * infrun.c (child_create_process): Use execlp to find the
2180 shell to exec our target program. This requires some fiddling
2181 with `environ' since there is no execlpe().
2183 Thu Aug 1 15:35:17 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
2185 * Makefile.in, doc/gdbrc.tex, doc/rc-* (new files):
2186 Minor rearrangement of refcard permits two new make targets--
2187 gdbrc.dvi DVI output for refcard, using CM fonts
2188 gdbrc.ps PostScript refcard, using PS fonts
2190 Wed Jul 31 16:46:21 1991 John Gilmore (gnu at cygint.cygnus.com)
2194 * TODO, Projects, WHATS.NEW, README: Update for gdb-3.98.
2195 * Makefile.in (gdb-all.texinfo): Avoid touching file if M4 dies.
2197 Wed Jul 31 16:35:58 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
2199 * doc/gdb.texinfo: last changes for release.
2200 Minor typo and formatting fixes; incorporated most fixes remaining from
2201 filed mail commenting on earlier drafts.
2203 Added warnings: pipes don't work in run command;
2204 conditions are converse of assertions;
2205 step over fn without debug info goes to next fn;
2206 vars may have "wrong" values near fn entrance, exit
2208 Added example from Kingston on printing repeated nonadjacent values
2210 Added explicit mention that in Emacs gdb mode C-c and C-z are like
2211 shell mode for signals
2213 Renamed "Stepping and Continuing" to "Continuing and Stepping" so it
2214 doesn't sound so much like its parent "Stopping and Continuing"; also
2215 moved entries on continue to top of section, so they don't get lost.
2217 Improved installation directions in appendix, added manual formatting
2220 Tue Jul 30 17:26:39 1991 John Gilmore (gnu at cygint.cygnus.com)
2222 * configure.in: Remove xm.h and tm.h even if we aren't linking
2223 new ones, so "./configure sun4; ./configure none" does the right
2224 thing. Assume that alldeps.mak and depend are already built in
2225 srcdir, and avoid running "make" (particularly "make depend",
2226 which involves "gcc") from inside configure. Build Makefile
2227 directly rather than building Makefile.conf first.
2228 * configure: Regenerate with above changes.
2229 * Makefile.in: Use $(BISON) to find bison. Roll VERSION
2230 to 3.98. Revise gdb.tar.Z procedure to produce a file
2231 called gdb-$(VERSION).tar.Z but which unpacks into a
2232 directory called "gdb". Move non-source files out of
2233 $(SFILES_SUBDIR). Pretty up alldeps.mak with comments.
2234 (depend): Don't try to do "gcc expread.y".
2235 (expread.o): Update dependencies by hand.
2237 Mon Jul 29 15:21:09 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
2240 Fixed a variety of small typos that prevented info from formatting
2241 cleanly; altered too-long heading for GPL Appendix, as discussed
2242 w/RMS; Changed date on cover to July 91.
2244 Fri Jul 26 13:20:02 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
2247 (1) Applied some fixes due to comments from Larry Breed (easier ones
2248 through chapsec 5.2)
2249 (2) Eliminated use of @footnote---had my doubts about it anyways, and
2250 it's broken in latest texinfo
2251 (3) Introduced *some* use of [] for optional arguments, where
2252 explanation is not simpler by listing cmd w arg and cmd w/out arg
2253 separately. Still not using @deffn.
2254 (4) Dropped in GPL-2. NOTE: one of GPL-2 or texinfo is broken; a
2255 couple of headings are too long. Need patches to texinfo or revision
2258 * Partial update to README (which still needs work for this
2259 release!): (1) use of configure corrected for new script,
2260 (2) "make gdb.dvi" and "make gdb.info" mentioned.
2262 Wed Jul 24 06:44:02 1991 John Gilmore (gnu at cygint.cygnus.com)
2264 * symtab.c (lookup_symbol): Don't complain right off about
2265 no debug symbols; use the misc function vector first.
2266 (list_symbols): Use misc function vector to find symbols
2267 that don't have debug info, and print them.
2268 (find_pc_symtab): Temporarily avoid fatal() when psymtab
2269 PC range doesn't match symtab PC range, as it does on the
2270 MIPS because our symtab reading isn't perfect.
2272 * dbxread.c (dbx_symfile_read): Make warning about
2273 "no debug symbols" slightly nicer.
2275 * source.c (select_source_symtab): If "main" symbol exists,
2276 but decode_line_spec can't find line info, don't just return
2277 a zero; try other source symtabs or give an error.
2279 * mipsread.c (parse_partial_symbols): Sort the psymtabs by
2280 their low addresses first, then rip through fixing high addrs.
2282 * ns32k-opcode.h (sfsr): Bugfix from Rune Nerg}rd,
2283 <runene@ifi.uio.no>.
2284 (NS32K_SVC_IMMED_OPERANDS): Reverse the #ifndef.
2286 Tue Jul 23 18:52:43 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
2288 * Minor, mostly mechanical, cleanup of doc subdir for clean
2289 makeinfo'ing and TeXing; also ensured gdb-all.texinfo (post-m4)
2290 and gdb.info (post- texinfo2 makeinfo) generated for distribution.
2292 Sun Jul 21 03:54:52 1991 John Gilmore (gnu at cygint.cygnus.com)
2294 Mostly MIPS and general symbol-reading fixups.
2296 * doc/gdbint.texinfo: Add documentation on symbol-reading
2299 * mipsread.c: Remove kludges around #include "ecoff.h".
2300 Remove redefinitions of a_magic, etc, no longer used.
2301 (parse_symbol, ): Convert "Internal:" printfs to complain()ts.
2302 Fix global overview comments to match symfile.c protocol.
2303 (mipscoff_new_init): Eliminate cur_hdr if we have one.
2304 (mipscoff_symfile_read): Eliminate unused code. Avoid
2305 sorting all the symtabs, when all we have read here is psymtabs.
2306 The symtabs are sorted as they are created anyway. Tell
2307 condense_misc_bunches whether we're mainline.
2308 (psymtab_to_symtab_1): Pass filename when recursing, to make
2309 stack trace more informative.
2310 (parse_partial_symbols): Assume cur_hdr as argument.
2311 (read_mips_symtab): Don't clobber cur_hdr, so it can be freed.
2312 Pass cur_hdr implicitly to parse_partial_symbols. Avoid checking
2313 the TYPE_NAME of char *, since that's done in symfile.c.
2314 (free_numargs, parse_symbol, add_symbol, add_block,
2315 shrink_linetable): Declare these fns void.
2316 (upgrade_type): Convert tree of if's to switch. Clean up
2317 bogus "off == 0" handling with a complaint. Avoid setting
2318 field bitpos and bitsize of array with lower and upper bounds.
2319 Check specified bitsize of elements against their actual type's
2320 bitsize, and complain if different. Complain about unknown
2322 (parse_fdr): Don't assume sizeof(char *) == sizeof (struct *).
2323 (psymtab_to_symtab_1): Print names of subsidiary files that
2324 are being read in. FIXME, we read far too many files. This code
2325 is not the problem, the problem is in parse_fdr where the psymtabs
2327 (cross_ref): Result should indicate that we used one aux entry
2328 normally, or two if we encountered a "next" entry. This used
2329 to leave the caller pointing at the wrong aux entry.
2330 (add_symbol): If overflowed cur_block, reallocate it larger,
2331 chase all pointers to it, and complain(), rather than clobber memory.
2332 (shrink_block): Use xrealloc rather than xmalloc-and-copy.
2333 (new_field): Only allocate one field initially, not two.
2334 Pull ++ out of macro argument. Simplify.
2335 (_initialize_mipsread): Avoid initialization of importd
2336 global_psymbols and static_psymbols.
2338 * symfile.c (psymtab_to_symtab): Depend on XXX_psymtab_to_symtab
2339 to properly set pst->symtab; avoid searching for it.
2340 (symfile_fns): Improve comments, add a FIXME.
2341 * dbxread.c: Update comments to reflect symfile protocol.
2342 (read_ofile_symtab, end_symtab): Return the symtab.
2343 (psymtab_to_symtab_1): Set pst->symtab.
2345 * coffread.c (coff_symfile_read): tell condense_misc_bunches
2346 whether we're mainline.
2348 * symfile.h (sym_fns): Remove unused sym_discard member.
2349 * coffread.c, mipsread.c, dbxread.c: Remove XXX_symfile_discard.
2351 * mtrace.c (mtrace): Take effect if mallwatch is set, even if
2352 the environment variable is not.
2353 * infcmd.c (finish_command): Use filtered printfs.
2354 * cplus-dem.c: Add struct tags to a few unnamed structs.
2355 * valops.c (value_coerce_array): Improve comments.
2356 * valprint.c (type_print_varspec_suffix): Print array size only
2357 if greater than zero.
2358 * m88k-tdep.c: Shift some lines left by one space, that had
2359 apparently been trashed at some point.
2360 * TODO: More things to do, a few got done.
2362 Thu Jul 18 22:46:05 1991 John Gilmore (gnu at cygint.cygnus.com)
2364 * symtab.h (LOC_EXTERNAL): Eliminate in favor of LOC_STATIC.
2365 (ldsymoff, ldsymlen, globals_offset, statics_offset): Improve
2367 * dbxread.c (read_dbx_symtab): LOC_EXTERNAL -> LOC_STATIC.
2368 * expread.y, findvar.c, symmisc.c: Ditto.
2369 * printcmd.c (address_info): Update printed forms of LOC_
2370 symbols. Elim LOC_EXTERNAL.
2371 (print_frame_args): Keep track of param stack offsets before
2372 re-looking up to find the local register param is kept in.
2374 * mipsread.c: Use <symconst.h> and <sym.h> rather than <syms.h>.
2375 Further integration of mipsread into gdb. Eliminate unused
2376 routines, duplicate declarations. Handle static symbols in
2377 psymtabs as well as external symbols. When reading symtabs,
2378 insert symbols into the correct block (global, static, or a local
2380 (read_mips_symtab, parse_partial_symbols): Don't pass useless
2382 (mipscoff_symfile_read): Don't call select_source_symtab.
2383 (parse_symbol): Use SYMBOL_VALUE_ADDRESS where appropriate,
2384 rather than SYMBOL_VALUE.
2385 (parse_external): Comment clobbering of top_stack.
2386 (parse_partial_symbols): Update comments. Allocate and parse
2387 static symbols as well as external symbols. FIXME, enum values
2388 are not handled in this pass, but should be. Inline new_psymbol.
2389 Use SYMBOL_VALUE_ADDRESS.
2390 (psymtab_to_symtab_1): Read symbols into global static block
2391 by default (until enter some function's local block context).
2392 (sort_blocks): Clean up STATIC_BLOCK as well as GLOBAL_BLOCK.
2393 (destroy_all_symtabs, new_psymbol): Eliminate, unused.
2395 * source.c (select_source_symtab): Select a source symtab
2396 from either the symtabs or, failing that, the psymtabs.
2397 (list_command): Update error message.
2398 (forward_search_command, reverse_search_command): Use getc, not
2399 fgetc, for speed. FIXME, add comment about buffers that die if
2400 overrun by long line.
2402 * values.c (unpack_field_as_long, modify_field): Avoid shifting
2403 by an entire word, which is not portable, if we have a 32-bit
2404 field. (Code in dbxread.c already turns such bitfields, if
2405 aligned, into ordinary ints, but fixing this will help for other
2406 symbol formats and for future changes.)
2407 * core.c (core_open): Handle ANSI const brain death.
2408 * utils.c (vprintf): Fix varargs typo.
2410 Sun Jul 14 00:42:53 1991 John Gilmore (gnu at cygint.cygnus.com)
2412 * findvar.c (find_var_value): Handle &function better.
2413 * TODO: Document work needed on &fn and &array.
2414 * printcmd.c (print_address_symbolic): New arg is the prefix
2415 to print if a name is printed.
2416 (print_address_demangle): Honor "set print address" now.
2417 Use new arg above to improve spacing of output.
2418 * valprint.c (val_print): When printing function pointers,
2419 print symbolic form too.
2420 * breakpoint.c (breakpoint_1): Use new print_address_symbolic.
2422 Mon Jul 8 19:02:46 1991 John Gilmore (gnu at cygint.cygnus.com)
2424 * core.c (memory_error): Reword error msg to mislead less.
2426 * mips-pinsn.c (print_insn_arg 'd'): Print $ with reg name.
2428 * mipsread.c (read_mips_symtab, read_the_mips_symtab,
2429 parse_partial_symbols): Use newer BFD internals (external_filehdr
2430 and external_aouthdr), byte-swap the fields that we care about
2431 before using them, and make the file header data local to
2432 read_the_mips_symtab rather than global.
2434 Sat Jul 6 01:34:15 1991 John Gilmore (gnu at cygint.cygnus.com)
2436 * ns32k-opcode.h (movmw, movmd): Fix opcodes. Bug fix
2437 from Rune Nerg}rd <runene@ifi.uio.no> on 5 Jul 1991.
2439 * main.c (command_line_input): Flush stdout and stderr
2440 before every call to readline. This reportedly fixes a bug
2441 that comes up in Sys V running emacs-gdb and/or xxgdb,
2442 when stdin/out are pipes or sockets.
2444 Thu Jul 4 14:47:06 1991 John Gilmore (gnu at cygint.cygnus.com)
2446 * configure.in, Makefile.in: Avoid rebuilding "depend" as much.
2447 Avoid declaring Makefile dependencies, because GNU Make stupidly
2448 tries to update it if we do.
2450 * coffread.c: Revise for minor changes to bfd internal coff
2453 * configure: If -template= is given a relative path, make it
2454 absolute before recurring in subdirectories.
2456 * configure, configure.in, Makefile.in: Install "configure" script
2457 as replacement for config.gdb.
2458 * config.gdb, Makefile.dist, Makefile.sdir: Remove
2459 * README: Update for configure, mostly. FIXME.
2461 * Add dec3100 as equivalent to littlemips. Indicate in all host &
2462 target config files that they are for the host. When the lines
2463 get copied into the Makefile, this makes it more obvious what's
2466 Mon Jun 24 23:49:07 1991 John Gilmore (gnu at cygint.cygnus.com)
2468 * sparc-opcode.h (trap opcodes): Avoid leading spaces or
2469 tabs, which end up in the disassembler output inadvertently.
2471 Wed May 29 23:01:03 1991 John Gilmore (gnu at cygint.cygnus.com)
2473 Make it compile cleanly in an ANSI GCC2 environment.
2475 * blockframe.c: <stdio.h>
2476 * cplus-dem.c: free takes a void *, ifdef __STDC__
2477 * dbxread.c (read_huge_number): avoid gcc2 bug hoisting calc of
2479 * defs.h (alloca): Avoid doing anything if alloca already def'd.
2480 * stddef.h, stdlib.h: Remove these files.
2481 * symtab.c: Avoid declaring qsort, close.
2482 * symfile.c: Avoid declaring close.
2483 * utils.c (vprintf): Declare "ap" arg as proper va_alist.
2484 * sparc-tdep.c: Avoid including lots of Sun-host-specific files.
2486 Assorted other changes.
2487 * dbxread.c: include "libaout.h", not "liba.out.h".
2488 * printcmd.c (print_frame_args): Set recurse properly for
2489 indentation of struct and array parameters.
2490 * valops.c (value_cast): Allow cast to void.
2491 * infrun.c (resume): If NO_SINGLE_STEP, call machine dependent
2492 single_step() in a target-independent fashion.
2493 * sparc-tdep.c (single_step): Don't call ptrace ourselves, just
2494 set up to be ready to continue. This makes us target independent.
2495 * infptrace.c (child_resume): Remove call to single_step; now
2496 can single step a SPARC target of any kind.
2498 Wed May 22 18:18:24 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
2500 * Makefile.dist, doc/gdb.texinfo, doc/*-m4.texinfo: split up GDB
2501 docn into separate sections---basically chapters, plus two loose
2502 pieces that can be configured to go in different places. This
2503 allows GNU m4 to preprocess the manual without coredumping.
2505 * Makefile.dist: tell TeX where to find texinfo.
2507 Mon May 20 12:15:04 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
2509 * Makefile.dist, doc/gdb.texinfo: respectively create, and use,
2510 the new target "rdl-apps.texinfo" which captures the Makefile
2511 variable that records where to find the Readline libraries.
2513 Sun May 19 05:36:59 1991 John Gilmore (gnu at cygint.cygnus.com)
2515 * tahoe-pinsn.c: #include "tahoe-opcode.h", not "opcode.h".
2516 * tm-tahoe.h (FIX_CALL_DUMMY): Ignore more parameters.
2517 * defs.h (const, volatile): Only define if not already defined.
2518 * Makefile.dist (gdb.tar.Z): Create doc subdir w/out CVS/RCS crud.
2520 * README: Update for release 3.95.
2521 * config.gdb: Don't create readline dir in subdir builds.
2522 * main.c: Include with "..." form for non-system include files,
2523 so "gcc -MM" for "make depend" works.
2524 Include readline files with "...h" rather than <readline/...h>.
2525 * mipsread.c: Include "ecoff.h" rather than "intel-coff.h".
2527 * coffread.c: Undo minor damage done by Rich Pixley. Use
2528 different internal and external representations of COFF
2529 data structures. Use new BFD routines for swapping them in and
2531 * symfile.c (free_named_symtabs): Avoid freeing file names that
2532 are null or empty. Old i960 tools seem to produce files that
2533 claim to have empty names, causing each successive file read
2534 to blow away the previous one.
2535 * sparc-xdep.c (deferred_stores): Repair minor damage by Rich.
2536 Move deferred_stores to top of file, but don't separate its
2537 #define's from its variable. Add commentary.
2538 * Makefile.dist: Fix Rich damage; undo "configure" changes in
2539 favor of keeping the (working) config.gdb. Move readline
2542 Fri May 17 12:49:56 1991 Per Bothner (via gnu at cygint.cygnus.com)
2544 * dbxread.c (read_struct_type): Try to handle g++ version 1 MI
2546 * infptrace.c (fetch_registers): no result, since now void.
2547 * tconfig/news: target depends on m68k-tdep too.
2549 Fri May 17 14:40:14 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
2551 * Makefile.dist: added readline/inc-*.texinfo to dependencies for
2554 * readline/inc-history.texinfo, readline/inc-readline.texinfo:
2555 applied various small fixes due to or inspired by RMS comments
2557 * doc/gdb.texinfo: finished using all RMS comments, save those for
2558 appendices on readline and cmd history (which are in other source
2561 Thu May 16 18:06:05 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
2563 * doc/gdb.texinfo: (1) Updated w/ref to RMS comments through
2564 chapter 9; (2) documented 'break' command's menu mode for
2565 overloaded names, in response to hgs problem report C++ p-31
2567 Wed May 15 11:02:48 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
2569 * doc/gdb.texinfo: (1) better introductory example; (2) more
2570 consistent use of @code, @samp, @file, @kbd throughout; small
2571 cleanups to first three nodes; (3) new "Contributors" node;
2572 (4) Appendix, Renamed Commands; (5) divert specialized startup
2573 instructions to "Targets" chapter for generic manuals, while
2574 leaving them up front for manuals specific to specialized
2575 environments; (6) apply fixes from RMS comments through chapter 4.
2577 * pretex.m4: modify explanatory text slightly (and redefine
2578 "regexp") to keep GNU m4 from complaining. (It still crashes
2579 later, but one step at a time...)
2581 Wed May 15 10:32:12 1991 John Gilmore (gnu at cygint.cygnus.com)
2583 * readline/readline.c (update_line): Avoid dereferencing a pointer
2584 before comparing it to its bounds. Saber caught this.
2585 (init_terminal_io): Don't set BC from the "pc=" termcap variable,
2586 and only set PC if tgetstr returned non-null. Saber caught this.
2588 Tue May 14 16:29:53 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)
2590 * Makefile.dist: put gdb.dvi stuff (updated to use M4 preprocessor
2591 stuff for config manual) here where it counts; updated
2592 to use new subdir structure (gdb/doc/).
2594 * Makefile: generated from above via
2598 * gdbint.texinfo: added instructions on generating gdb.info* files
2599 locally for release. These are ordinary info
2600 files, formatted from gdb.texinfo (via gdb-all.texinfo, see
2601 Makefile)---but due to use of texinfo 2, can't count on makeinfo
2602 to generate these, so we distribute them already formatted.
2604 * gdb.texinfo: included full Info node and menu crud (as generated
2605 by C-u M-x texinfo-master-menu using the texinfo-2 elisp code).
2607 * Makefile: updated "gdb.dvi" target to use M4 preprocessor;
2608 put in comments-for-future gdb.info target (one day makeinfo will
2611 Tue May 14 13:51:36 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)
2613 * gdb.texinfo: Updated to include new or old undocumented
2614 commands, at least the following (perhaps some others I forgot to
2615 record): info f, info float, info path, info program, info s, info
2616 set, info source, info terminal, info types, info user, set/show
2618 Also covered all recent GDB command renames for v4.
2620 Mon May 13 14:57:46 1991 John Gilmore (gnu at cygint.cygnus.com)
2622 * mipsread.c: Rather than keeping count of how many symtabs
2623 and psymtabs we have, for sorting purposes, count them when
2624 we need to sort. This fixes bug in rereading of symbol tables.
2626 Fri May 10 15:43:33 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)
2628 * infcmd.c: renamed "info path" to "show paths"

2642 * coffread.c, exec.c, infptrace.c, inftarg.c, remote.c, solib.c,
2643 symtab.h, target.c, target.h: Lint.
2644 * core.c: setup and select frame after reading shared libs,
2645 else reading shared libs will clobber them. Lint.
2646 * utils.c (error): Force out any buffered wrap text.
2648 Fri May 3 22:01:56 1991 John Gilmore (gnu at cygint.cygnus.com)
2650 * remote.c: Remove decls of memory_insert_breakpoint
2651 and memory_remove_breakpoint, no longer used. (Suggestion of
2654 * Makefile.dist: use ${subdir} in paths of BFD and LIBIBERTY,
2655 to make it easier to interface to "configure"'d libraries.
2657 Fri May 3 13:10:01 PDT 1991 Roland Pesch (pesch at fowanton.cygnus.com)
2659 * valprint.c: introduce "set p", "set pr", "show p" and "show pr" as
2660 aliases for set/show print.

2788 not {value_as,unpack}_long on CORE_ADDR's.
2789 Use longest_to_int (added to defs.h) instead of cast to int.
2790 Remove from_tty arg to mod_path.
2791 Put symfile_bfd in {coff,dbx}read.c not symfile.h.
2792 Use OP_NULL instead of 0 where dummy enum exp_opcode needed.

3211 * dbxread.c (read_dbx_symtab): Allow N_SOL to cleanly take us back
3212 to the main file, as well as to include files. Also, put global
3213 functions into the global psymtab, to make "i fun" work.
3214 (end_psymtab): Free named symtabs and psymtabs for a file, once a
3215 new psymtab for it has been read.
3216 * coffread.c (end_psymtab): Free named symtabs and psymtabs for
3217 a file, once a new symtab has been read for it.
3218 * mipsread.c: FIXME. We need to do the same for MIPS, but it

3220 queued to the psymtab list.
3222 * symfile.c (symbol_file_add): Use filtered printing and wrap it.
3223 If we have wiped out any old symbol tables, clean up at end of

3239 static psymbols list.
3240 (types_info): Restore this function from its untimely #if 0.

3264 * exec.c (exec_ops): Add_syms_addr is valid in our tvec.
3265 (set_section_command): New command ("section xxx yyy" -- should
3266 be renamed to "set section xxx yyy" FIXME) which sets the
3267 base address of a section of the exec file, overriding the
3268 virtual address that BFD reports.
3270 Fri Apr 5 17:14:39 1991 John Gilmore (gnu at cygint.cygnus.com)
3272 * exec.c: Add add_syms_addr_command to exec_ops, so you can

3277 * tm-i386v.h (FLOAT_INFO): Don't define it, since the code
3278 for printing the float info is host-dependent, not
3279 target-dependent. FIXME.
3280 * i386-pinsn.c: Move #includes to top, remove useless ones.
3281 * i386-tdep.c: Don't bother including <.../reg.h> since we
3282 don't use it (and it doesn't exist on host systems).

3285 Convert negative numbers properly.
3286 (ieee_test): Make numbers really random; fix format arg.
3288 * infcmd.c (attach_command, detach_command): Don't repeat on CR.
3289 * core.c (core_detach): Unpush core_ops, which might not be on
3290 top. We used to just pop the top, which broke things. Don't
3291 need dont_repeat() any more.
3292 (core_file_command): Psst! Don't repeat it.
3293 * remote-nindy.c (nindy_detach): Don't need dont_repeat() now.
3294 * expprint.c (print_subexp): Avoid switch fallthru on
3295 BINOP_ASSIGN_MODIFY, so we can print += and such.
3296 * frame.h: Fix typo.
3297 * inflow.c (kill_command): After killing inferior, print our
3298 current frame in the core file, if we have one.
3299 (generic_mourn_inferior): When inferior dies, either select
3300 the current frame (in the new target, e.g. core file), or
3301 set both the current and selected frames to NULL.
3303 Changes from Peter Schauer.
3305 * infptrace.c: Avoid <sys/ptrace.h> on USG.
3307 * Make all file names fit in 14 characters (sigh and damn!):
3308 mv hp300hpux-xdep.c hp300ux-xdep.c
3309 mv symmetry-xdep.c symm-xdep.c
3310 mv symmetry-tdep.c symm-tdep.c

3316 mv remote-sa.m68k.shar rem-m68k.shar
3317 mv remote-multi.shar rem-multi.shar
3318 * Makefile.dist, README, config.gdb, convex-pinsn.c,
3319 tconfig/symmetry, tconfig/vxworks960, tconfig/vxworks68,
3320 xconfig/hp300hpux, xconfig/symmetry: Change names to shorter
3323 * command.c (user_info_1, user_info): New command for listing
3324 the user-defined commands.
3326 Wed Apr 3 15:00:26 1991 John Gilmore (gnu at cygint.cygnus.com)
3328 * dbxread.c (really_free_pendings): Clear file_symbols
3329 and global_symbols after freeing them; otherwise, running
3330 this function twice (if it appears twice on the cleanup
3331 chain), we try to free things twice.
3333 * dbxread.c (read_dbx_symtab): Calculate end_of_text_addr
3334 based on text_addr (the address of text in core), not on addr (the
3335 offset between text in the .o file and in core). This change
3336 is from Peter Schauer.
3338 * main.c: Define ALL_CLEANUPS as a cast of zero.
3339 (return_to_top_level): Use it.
3340 (main): Do all cleanups after each command run as part
3341 of the gdb startup sequence. Also do all cleanups before
3342 entering the command loop, and every time we exit the command
3343 loop and reenter. Before, the cleanups from the startup sequence
3344 were being left undone until the first error!
3345 (command_loop): Rename do_nothing cleanup to command_loop_marker
3346 so we can see it easily when examining the cleanup chain.
3347 (init_signals): Add another do_nothing for signal handling.
3348 (quit_command): Only try to kill target if it has execution.
3349 Problems in the target stack got us into a state where
3350 inferior_pid was nonzero but none of the targets had execution.
3351 In this state you couldn't exit gdb.
3353 * dbxread.c: Two changes from Peter Schauer.
3354 (echo_command): Fflush output after an echo command.
3355 (show_history): Pass all args to cmd_show_list.
3357 * utils.c (init_malloc): Call mtrace to turn on tracing
3358 if the environment variable MALLOC_TRACE is set to a file name.
3359 * mtrace.c: Add source file which provides a log of every malloc,
3360 free, and realloc to a trace file.
3361 * mtrace.awk: Add source file which analyzes the trace file.
3362 * Makefile.dist (GNU_MALLOC, MALLOCSRC): Add mtrace.{c,o,awk}.
3363 (VERSION): Roll to 3.94.3.
3365 * breakpoint.c (breakpoint_1): Add a space to "i watch" output.
3366 (check_duplicates): Don't bother with watchpoints.
3367 (set_raw_breakpoint): Comment about danger of this routine.
3368 (watch_command): Parse and eval all args before calling
3371 * solib.c (find_solib): Avoid error in referencing memory to
3372 see if any more shared libraries have been added. This is
3373 particularly useful if the target has terminated. Bug reported
3376 Changes from Peter Schauer <pesrem@regent.e-technik.tu-muenchen.de>
3377 in bringing up 3.94.2 on the Sun-3.
3379 * Makefile.dist: Include CFLAGS in rule for cplus-dem.o.
3380 * breakpoint.c (enable_breakpoint): Check for valid watchpoint
3381 expression (in scope) before reenabling watchpoint.
3382 * signame.c (init_sigs): Add missing declaration of i, fix
3383 sys_siglist declaration.
3384 * source.c (list_command): Fixed range computation to use
3386 * stack.c (backtrace_command): Do not allow command if target has
3387 no stack, print informative error message.
3388 * target.c (target_command): Do not write into command line
3389 because this fails if the target command is used in a user defined
3390 command. [This change was enhanced by gnu to support any-
3391 unique-prefix matching on target names.]
3392 * valops.c (value_struct_elt): Avoid infinite loop on an
3393 erroneous attempt to print the member of function (try p main.p).
3395 Mon Apr 1 17:05:45 1991 John Gilmore (gnu at cygint.cygnus.com)
3397 * expread.y (name_no_typename): Avoid reduce/reduce errors
3398 caused by ambiguity in handling NAME_OR_INT and NAME_OR_UINT.
3399 Since the GDB parser really doesn't use name_no_typename in a
3400 name-only context, the parser can't tell the diff between
3401 names and numbers here. Avoid allowing a name_no_typename
3402 to be a NAME_OR_*INT to resolve the conflict.
3404 Sun Mar 31 20:12:07 1991 John Gilmore (gnu at cygint.cygnus.com)
3406 Bugfixes from Mark Fox (markf@wrs.com) (test=testField.c):
3408 * valprint.c (val_print_fields): bitfield printing didn't handle
3409 byte order. Indirect through a few more fns to cope.
3411 * values.c (modify_field): also cope with byte order.
3413 Sat Mar 23 10:02:21 1991 John Gilmore (gnu at cygint.cygnus.com)
3415 Cleanup for release 3.94.2:
3417 * Makefile.dist: Pull REMOTE_OBS. Fix saber includes for BFD
3418 include files. Roll version to 3.94.2.
3420 * coffread.c (init_stringtab): Read length into unsigned char
3421 array before swapping; don't assume 32-bit longs.
3423 * target.c (target_info): Don't bother with get_sym_file, just use
3424 the symfile global variable.
3425 * symtab.h, symfile.c (get_sym_file): Delete it.
3427 * dbxread.c (dbx_symfile_init): Don't depend on long == 4 bytes.
3428 (define_symbol): Set symbol line number to 0 if not gcc-compiled.
3429 (read_type): Replace one more error() with complain().
3431 * mipsread.c (parse_partial_symbols): Replace printf with complain.
3433 * i960-tdep.c: Fix copyright attribution.
3435 * config.gdb: Quote all backquotes in doublequotes. You can
3436 quote me on that. BSD 4.4 shell found this one.
3438 * infptrace.c (throughout): The third argument to ptrace is an
3441 * infrun.c (wait_for_inferior): When program has terminated, we
3442 have to call target_terminal_ours before we pop that target off
3443 the stack (e.g. before a call to target_kill or
3444 target_mourn_inferior). This fixes problem where a program
3445 terminates, then GDB stops for (tty output) and you have to type
3446 "fg" to the shell to resume it. FIXME: This code for what to
3447 do after termination really should be in normal_stop instead.
3449 * gdbcore.h (read_memory_check): Change declaration; it changed
3452 * terminal.h: Include <sgtty.h> before <sys/ioctl.h>, since in BSD
3453 4.4 prereleases, this avoids a bug in their sgtty compatability
3455 * remote.c: Use terminal.h rather than hand-rolling the same.
3457 * signame.c, signame.h (psignal): Arg is unsigned, not int.
3458 * utils.c (strsave, strstr): Fix arg types.
3459 * valprint.c (val_print): lint
3461 MIPS symbol table support from Per Bothner:
3463 * symfile.c (symtab_fns): Remove initializer table that needs to
3464 be hacked for each new symbol file format supported.
3465 (add_symtab_fns): New function, chains symbol table
3466 handlers into the global list.
3467 (symfile_init): Search this list.
3468 * symfile.h: Add next pointer, declare add_symtab_fns.
3469 * coffread.c (_initialize_coffread): Call add_symtab_fns.
3470 * dbxread.c (_initialize_dbxread): Call add_symtab_fns.
3472 * mipsread.c (psymtab_to_symtab_1): return void instead of (struct
3473 symbol *). Thus, we no longer need the hack to trash
3474 pst->filename. Good, since that hack confused code in symfile.c!
3476 (reorder_symtabs, destroy_all_symtabs): Removed static
3477 all_symtabs, which was used to qsort symtabs in reorder_symtabs.
3478 Instead, the latter now uses a temporary array (stack-allocated
3479 from an obstack, and then freed).
3481 (parse_symbol): Added a hack to fix up BLOCK_{START,END} if they
3482 haven't been set in the outermost stBlock of a procedure. This was
3483 a problem with f77 binaries on Ultrix 4.?.
3485 (new_symtab, new_symbol, new_type): Continue changing code to use
3486 obstacks more and otherwise conform to dbxread internal style.
3487 Made the free_code of symtabs be free_linetable (as in dbxread)
3488 instead of free_contents. This implies memory leaks when reading
3489 a new symbol table, until the conversion is finished. Did change
3490 (struct symbol) and (struct type) to be allocated on the
3491 symbol_obstack. Blocks and blockvectors are among the things
3494 * mipsread.c (parse_partial_symbols, parse_fdr): It hasn't been
3495 tested much, but it solved one problem (reported by Meissner), and
3496 cleans up some other things. The problem happened when an
3497 included file contains actual code (functions) and not just
3498 definitions. The mips coff is a little inconvenient there, since
3499 it may cause a procedure to be mapped to the wrong psymtab.
3501 * mips-tdep.c (heuristic_proc_desc): Minor cleanup.
3502 * mips-xdep.c (fetch_core_registers): Minor cleanup. FIXME,
3503 this will need work for the new core paradigm.
3505 Opcode patches from the net:
3507 * mips-opcode.h: fix incorrect disassembly of the mfc1, cfc1, and
3508 ctc1 instructions. Also, the cvt.d.w and cvt.s.w instructions were
3509 missing altogether - they are added here. From Bruce Bauman.
3510 * mips-opcode.h: The low mask for C0 instructions was too small.
3511 From Garrett Lau. I modified the fix to check the entire 32-bit
3514 * ns32k-opcode.h: Fix opcodes for deiw and deid. From Bruce
3517 Thu Mar 21 12:56:46 1991 John Gilmore (gnu at cygint.cygnus.com)
3519 Roll in changes from Per Bothner (Tue, 25 Sep 90 11:11:04):
3521 * dbxread.c (read_type): Pointer subtraction (value_sub in
3522 valarith.c) sometimes failed because the types of the
3523 pointers being subtracted were not identical.
3524 These differed because dbxread.c was allocating pointer types
3525 using dbx_alloc_type+smash_to_pointer_type instead of
3526 lookup_pointer_type. I failed to find a justification for the
3527 former, so I changed it to use the latter. Similarly, I
3528 replaced smash_to_function_type by lookup_function_type,
3529 and smash_to_reference_type by lookup_reference_type.
3531 * mipsread.c (parse_symbol, upgrade_type, parse_procedure,
3532 _initialize_mipsread): corresponding changes.
3534 * symtab.c (smash_to_{pointer,reference,function}_type): eliminate.
3536 * source.c (mod_path): Do tilde_expand on each component of the path,
3537 rather than on the (list of) paths as a whole.
3538 (print_source_lines): Set first_line_listed in addition to
3539 current_source_symtab and current_source_line. If the source was
3540 not findable, after a "dir" command to fix the problem,
3541 a "list" would get the wrong lines.
3543 While I was there... (gnu):
3545 * dbxread.c (read_type): Change error to complaint.
3547 Thu Mar 21 12:56:46 1991 John Gilmore (gnu at cygint.cygnus.com)
3549 First attempt at detailed understanding of symbol table memory alloc.
3551 * dbxread.c (dbx_symfile_read): Free our string table if we
3552 aren't the mainline. Free the "info" struct since we're done with
3554 (init_psymbol_list): Free any previously allocated psymbol lists.
3555 (): FIXME: Should realloc-down the psymbol lists when done reading
3556 the main symbol file?
3558 * symmisc.c (free_symtab): Free fullname field too.
3560 * xm-hp300hpux.h (USG): #undef then #define so Makefile can -D.
3561 (REGISTER_ADDR): Make result type unsigned int.
3563 * xconfig/{i386*,hp300hpux,altosgas,altos}: All config files that
3564 define REGEX must also define REGEX1 (its dependency).
3566 Tue Mar 19 21:28:57 1991 John Gilmore (gnu at cygint.cygnus.com)
3568 * tconfig/i960: No longer works, points you at vxworks960 or
3571 * xgdb.c, XGDB-README: Remove file. Users can get the much
3573 * Makefile.dist: Remove all trace of xgdb.
3575 * breakpoint.c (breakpoint_1): Pass demangle arg to
3576 print_address_symbolic.
3577 (clear_breakpoints): Remove unused function.
3578 (breakpoint_re_set_one): Guts of breakpoint_re_set.
3579 (breakpoint_re_set): Use catch_errors to do them all anyway.
3581 * gdb-int.texinfo (Host versus Target): Add section on what is
3582 a "host" feature versus what is a "target" feature.
3584 * infcmd.c (path_command, path_info): Handle the PATH variable
3585 (object search path) as conveniently as the source search path.
3586 * environ.c (set_in_environ): Set some vars in GDB's environment,
3587 in addition to the child's. PATH, G960BASE, G960BIN for starters.
3588 * source.c (mod_path): New function, from guts of
3589 directory_command, modifies a path. Used by path_command.
3590 (directory_command): Call it.
3591 * defs.h (strsave): Declare.
3593 * utils.c (sevenbit_strings): Add new printing option.
3594 (printchar): Use it.
3595 (strsave): Provide this handy helper routine.
3596 (set_width_command): Rename set_screen_width_command.
3597 (_initialize_utils): "set screen-width" => "set width";
3598 "set screen-height" => "set height"; add sevenbit-strings.
3600 * infcmd.c (do_registers_info): Print floating point registers
3601 in raw hex as well as float format, regardless of whether it is
3602 a "virtual" convertible register.
3603 * tm-sparc.h (PRINT_REGISTER_HOOK): Print every pair of float
3604 regs as a double, just in case it's being used that way.
3605 * values.c (unpack_long): Comment on array/function coercion.
3606 (unpack_double): Argument is in target byte order now. For
3607 integer arguments, just call unpack_long and float the result.
3608 * m68k-tdep.c: include defs.h for "const" handling.
3609 * remote-nindy.c: Use ieee-float stuff.
3610 (nindy_fetch_registers): Unpack double regs to host double, then
3612 (nindy_store_registers): Pack extendeds to host double, flip
3613 around by misusing unpack_double, send as target double.
3615 * tm-vxworks68.h (FRAME_CHAIN): Handle current frame pointer of
3616 zero, as when stopped at the first instruction of a process.
3618 * blockframe.c: Fix filename in comment (param.h => tm.h).
3619 * sparc-tdep.c (skip_prologue): More explicit nudging comments.
3620 * tm-68k.h: Fix typos.
3622 Fri Mar 15 01:09:34 1991 John Gilmore (gnu at cygint.cygnus.com)
3624 Changes from a bringup on the DEC Vax under Ultrix 4.0.
3626 * coredep.c (fetch_core_registers): Pass end-address of register
3627 section to register_addr as expected. Don't call supply_register
3628 if we'd just pass it garbage.
3630 * dbxread.c (read_dbx_symtab): Skip N_NSYMS on Ultrix.
3632 * exec.c (xfer_memory): Use boolean xfer_fn result, not int.
3634 * target.c (push_target, target_info): Cast enums to int for < or
3637 * stack.c (print_frame_info): Identify source file & line
3638 even if we can't print it.
3640 * xm-vax.h (MISSING_VPRINTF): No longer missing in Ultrix V4.0.
3642 Sat Mar 9 10:08:20 1991 John Gilmore (gnu at cygint.cygnus.com)
3644 Clean up IEEE floating point support.
3646 * ieee-float.h: New file.
3647 * ieee-float.c: Write real routines to convert between host
3648 doubles and various target IEEE extendeds.
3649 * m68k-xdep.c: Eliminate assembler code for extended floats.
3650 * xconfig/{3b1,altos,altosgas,hp300bsd,isi,news,news1000,sun2os3,
3651 sun2os4,sun3,sun3os3,sun3os4}: Eliminate use of m68k-xdep.o.
3652 * tm-i960.h, tm-68k.h (REGISTER_CONVERT_TO_VIRTUAL,
3653 REGISTER_CONVERT_TO_RAW): Use ieee_extended_to_double and
3654 double_to_ieee_extended.
3655 * i960-tdep.c: Define ext_format_i960.
3656 * m68k-tdep.c: Define ext_format_68881.
3657 * sparc-tdep.c: Define ext_format_sparc, though unused.
3658 * Makefile.dist (HFILES): Add ieee-float.h.
3659 * inftarg.c: #include "ieee-float.h" for the REGISTER_CONVERT
3662 Obsolete the "coffstrip" program in favor of using BFD's strip.
3664 * nindy-share/coffstrip.c: Remove file.
3665 * nindy-share/nindy.c (coffstrip): Routine to run bfd_strip.
3666 * Makefile.dist: Remove references to nindy-share/coffstrip.c.
3667 * tconfig/nindy960: Remove reference to coffstrip.o.
3669 * Makefile.dist: Roll version number to 3.94.1 (not yet final).
3671 Wed Mar 6 09:56:45 1991 John Gilmore (gnu at cygint.cygnus.com)
3673 * symfile.h: Add symfile_bfd, common between dbxread and coffread.
3674 * dbxread.c: Remove static symfile_bfd.
3675 * infcmd.c (do_registers_info): Add PRINT_REGISTER_HOOK, though
3677 * inftarg.c (child_detach): Pop the child_ops vector if the
3678 detach is successful.
3679 * remote-nindy.c (nindy_create_inferior): Don't push a new
3680 nindy_ops since nindy uses the same one for execution and memory
3682 * core.c (core_ops): Use child_attach and child_create_inferior
3683 rather than default attach and create_inferior functions.
3685 Handle floating point registers in core files.
3687 * sparc-xdep.c (fetch_core_registers): Rewrite for float support.
3688 * sun3-xdep.c (fetch_core_registers): Rewrite for float support.
3689 This version untested since BFD doesn't yet support sun3 core
3691 * hp300hpux-xdep.c: Rewrite fetch_core_registers to new calling
3692 conventions. Fix comments and style. This version has not
3693 been compiled yet, since we have no HP inhouse.
3694 * core.c (get_core_registers): Look for two sections, ".reg"
3695 and ".reg2", and pass both to fetch_core_registers sequentially.
3697 Revise directory path yet again.
3699 * source.c (forget_cached_source_info): Not static any more.
3700 (init_source_path): New default source path is "$cdir:$cwd".
3701 (dir_command): Handle variable arguments ($cdir, $cwd).
3702 (source_info): Print "Compilation directory" rather than
3703 "Originally compiled in" to remind people of $cdir.
3704 (openp): If the path contains $cwd, use current directory.
3705 (open_source_file): If compilation directory is known, replace
3706 first $cdir in path with the compilation directory.
3707 (print_source_lines): Even if we can't print the lines, set the
3708 current symtab and line for future commands like "info source" or
3709 "breakpoint". Also, error message now contains the file name,
3710 line number, and file access error message.
3711 (_initialize_source): Fix help text to describe changes.
3712 * main.c (cd_command): Forget cached source info when we chdir.
3713 * utils.c (strstr): Add simple implementation.
3715 Tue Mar 5 01:41:40 1991 John Gilmore (gnu at fowanton.cygnus.com)
3717 * coffread.c (read_one_sym, init_linetable, init_stringtab):
3718 Byte-swap COFF symbol tables if necessary when reading them in.
3719 Use complain() to replace error message in one spot. Needs
3720 corresponding change in bfd/coff-code.h to make some symbol
3721 swapping routines non-static.
3723 Mon Mar 4 00:53:40 1991 John Gilmore (gnu at cygint.cygnus.com)
3725 Merge changes from Eirik Fuller, for UTek.
3727 * defs.h (errno): Add declaration.
3728 * altos-xdep.c, arm-xdep.c, convex-xdep.c, gould-xdep.c,
3729 hp300hpux-xdep.c, infrun.c, inflow.c, infptrace.c, i386-tdep.c,
3730 i386-xdep.c, pyr-xdep.c, mips-xdep.c, remote-eb.c, remote-nindy.c,
3731 remote-vx.c, source.c, standalone.c, stuff.c, sun386-xdep.c,
3732 symmetry-tdep.c, symmetry-xdep.c, umax-xdep.c, utils.c: Eliminate
3733 declarations of errno.
3735 * remote-eb.c: Define B19200 and B38400 as EXTA and EXTB.
3737 * remote-vx.c: Include <sys/time.h> for UTek; Sun gets it via
3738 <rpc/rpc.h> and <rpc/types.h>.
3740 Sat Mar 2 15:47:55 1991 John Gilmore (gnu at cygint.cygnus.com)
3742 * i960-tdep.c (examine_prologue): Add new argument limit,
3743 which stops the scan at the end of the prologue, or at the PC.
3744 This fixes a problem where it walks down into the code for the
3745 user's statements if that code looks like function prologues.
3746 Mark Fox and I have been bouncing this code back and forth, making
3747 small changes to it. Callers changed to match.
3749 Tue Feb 26 01:47:07 1991 Cygnus John Gilmore (cygnus at yuba)
3751 Cleanup for gdb-3.94 release final:
3753 * Makefile.dist: Remove remote-vx.c, remote-nindy.c, and all
3754 the .c files from vx-share and nindy-share, from the various
3755 macros, since they are not found via ALLDEPFILES.
3756 (SFILES): Add tm-i960.h.
3757 (alldeps.mak rule): Break out ALLDEPFILES_MAINDIR and
3758 ALLDEPFILES_SUBDIR. List all the nindy and vxworks subdir files
3760 (TAGFILES_MAINDIR): Change ALLDEPFILES to ALLDEPFILES_MAINDIR.
3761 (gdb.tar.Z): Use ALLDEPFILES_SUBDIR as well as SFILES_SUBDIR.
3763 Mon Feb 25 16:02:35 1991 Cygnus John Gilmore (cygnus at oldman)
3765 * am29k-tdep.c: Add contribution line.
3766 (examine_prologue): Cache information about function prologues in
3767 the misc-function-vector to avoid lots of references over the
3768 serial line while examining instructions.
3770 * core.c (core_close): New function made from cleanup_core.
3772 * core.c, exec.c, inftarg.c, remote-eb.c, remote-nindy.c,
3773 remote-vx.c, remote.c, target.c, target.h,
3774 Update target_ops vector to add attach, close, and load entries.
3775 Use add_syms_addr_command, not add_file_addr_command, for
3776 add_file. Break out close routine from existing code.
3778 * dbxread.c (really_free_pendings): Don't free pending_blocks;
3779 they are in an obstack.
3780 (read_dbx_symtab): Relocate end_of_text_addr in the psymtab.
3782 (define_symbol): Add symbol type parameter; change callers;
3783 pass type parameter to DBX_PARM_SYMBOL_CLASS macro to allow
3784 it to influence the symbol class on the i960.
3785 (define_symbol): Swap LOC_CONST's into target byte order.
3787 * exec.c (exec_close): New function.
3788 (exec_file_command): Call it.
3790 * findvar.c (read_relative_register_raw_bytes): Doc byte order,
3791 Fix byte order of frame pointer.
3792 (read_var_value): Result of 0 if var's value can't be found,
3793 e.g. missing FRAME_ARGS_ADDRESS. Byte-swap LOC_CONST and
3794 LOC_LABEL values to target order. Add LOC_LOCAL_ARG.
3795 (locate_var_value): Use read_var_value and use its lazy address
3796 as the location of the var's value. Lint.
3798 * i960-pinsn.c (next_insn): Add routine from vxgdb for scanning
3801 * i960-tdep.c (arg_address, i960_frame_find_saved_regs): Remove
3802 obsolete Intel versions in favor of vxgdb versions.
3803 (check_host, byteswap, byteswap_val, reorder_val): Eliminate
3804 code dealing with byte order of values, which Intel did in host byte
3805 order rather than gdb-4's target byte order.
3806 (i960_frame_chain_valid): Move to nindy-tdep.c.
3807 (examine_prologue, skip_prologue, frame_find_saved_regs,
3808 frame_args_address, leafproc_return, saved_pc_after_call,
3809 pop_frame): Add vxgdb versions from Mark Fox.
3810 (examine_prologue, frame_struct_result_address): Add code
3811 to deal with the saved value of G13 (struct return address
3813 (frame_args_address): Modify Mark's version to prefer the
3814 saved value over the current value in the topmost frame.
3815 Cache result in the frame info to avoid performance hair in
3817 (print_fault): Add gdb960 code for printing faults.
3818 (_initialize_i960): Actually call check_host.
3820 * ieee-float.c (ieee_extended_to_double, ieee_double_to_extended):
3821 add stub routines. FIXME, these currently just return zero!
3823 * infcmd.c (program_info): Use PRINT_RANDOM_SIGNAL.
3824 (attach_command): Call target_attach, not target_open, now.
3826 * infrun.c (normal_stop): Make global, not static, for vx_attach.
3827 (child_attach): Rename from child_open.
3828 (wait_for_inferior): Use PRINT_RANDOM_SIGNAL. If stop_pc is zero,
3829 don't confuse it with a zero step_resume_break_address.
3831 * inftarg.c (child_detach): Eliminate inferior_pid test.
3832 (child_files_info): Clean up message a bit.
3833 (child_ops): Use child_attach, not child_open, to attach.
3835 * mem-break.c: #ifdef out the whole file if BREAKPOINT is not
3836 set (e.g. on VxWorks or NINDY). Move read_memory_nobpt from
3837 findvar.c to here, since it depends on the contents of the
3838 shadow_contents of breakpoints, but keep if #if 0 since it is
3841 * nindy-tdep.c: New file, contains nindy_frame_chain_valid, moved
3844 * printcmd.c (address_info): Handle LOC_LOCAL_ARG. Lint.
3845 (ptype_command, display_command): Eliminate have_inferior_p and
3846 have_core_file_p in favor of target_has_stack or
3847 target_has_execution.
3848 (print_frame_args): Handle LOC_LOCAL_ARG. Eliminate duplicate
3849 code for actually finding the values of arguments, though we still
3850 keep track of the maximum stack offset for use in printing unnamed
3851 arguments. Handle missing FRAME_ARGS_ADDRESS.
3853 * remote-nindy.c (i960_print_fault): Move to i960-tdep.c.
3854 (struct nindy_regs): Define registers passed to/from nindy.
3855 (nindy_fetch_registers, nindy_store-registers): Translate between
3856 nindy and GDB formats for the registers.
3857 (dcache_init): Statically allocate the cache, since it was being
3858 allocated by a malloc that was never freed anyway.
3859 (nindy_create_inferior): Error, not core dump, if no exec file.
3860 (nindy_before_main_loop): Use target_load, not target_add_file.
3862 * remote-vx.c (net_load): Specify large timeout for load
3863 requests. Allow user to break out with INTERRUPT.
3864 (net_break): Remove useless code, clean up. Change callers.
3865 (parse-args, skip_white_space, find_white_space): Clean up arg
3866 parsing to cope with quoted strings.
3867 (net_wait, net_quit): Never call error, just return status.
3868 (vx_read_register, vx_write_register): Cleanup status checking.
3869 #ifdef the code based on which CPU we are using (960 or 68k),
3870 FIXME, this should be completely general but it isn't yet.
3871 (vx_xfer_memory, vx_resume): Cleanup status checking.
3872 (vx_run_files_info): Improve message.
3873 (vx_load_command): Renamed from vx_add_file_command. Allow load
3875 (net_ptrace): Remove unused routine.
3876 (vx_wait): Adopt code from vxgdb960 to cope with broken
3877 connections to target machine and prompt to disconnect. Remove
3878 debug printouts. Map some EVENT_'s to SIGnals.
3879 (add_symbol_stub, vx_open): Print names of object files we found,
3880 and "ok" if we read their symbols OK. Clarify output in general.
3881 (vx_attach, vx_detach, vx_kill): Add these commands.
3882 (vx_convert_from_virtual, vx_convert_to_virtual): Simplify.
3883 (vx_run_ops): Turn off all_mem, to avoid spurious msg in the
3884 "info files" output, and create_inferior, since we already have
3887 * stack.c (frame_info): Replace Frame_unknown with 0.
3888 (print_frame_arg_vars): Handle LOC_LOCAL_ARG.
3889 (return_command): Pop until the PC matches as well as the FP,
3890 so it works even if the FP is shared with another function,
3891 as in "frameless" or "leaf" procedures.
3893 * symfile.c (load_command): renamed from add_file_target_command.
3894 (add_syms_addr_command): renamed from add_file_addr_command.
3895 (add_syms_command): Stub to call target_add_syms.
3896 (_initialize_symfile): Change command names and descriptions,
3897 add-file => add-syms, and load from alias to its own command.
3899 * target.c (kill_or_be_killed, maybe_kill_then_attach,
3900 maybe_kill_then_create_inferior): Default for attempts to start
3901 a process, if one is already running, is to ask about killing
3902 it and retry if yes.
3903 (upstack_create_inferior): #if-0 it, strata obsolete it.
3904 (push_target, unpush_target, pop_target): to_close() a target
3905 before unstacking it.
3906 (target_info): Renamed from target_files_info.
3907 (_initialize_targets): Rename "i files" as "i target", accessible
3910 * target.h: Improve comments about the target_ vectored routines.
3912 * tm-i960.h: Remove NINDY-specific stuff to tm-nindy960.h.
3913 Convert commenting style to standard GNU style.
3914 (DBX_PARM_SYMBOL_CLASS): allow LOC_LOCAL_ARG's to be recognized.
3915 (SKIP_PROLOGUE): No longer a no-op.
3916 (SAVED_PC_AFTER_CALL): Now handles leaf procedures.
3917 (*_REGNUM): Sort register numbers.
3918 (REGISTER_BYTES, REGISTER_BYTE, REGISTER_RAW_SIZE,
3919 MAX_REGISTER_RAW_SIZE, REGISTER_CONVERTIBLE,
3920 REGISTER_CONVERT_TO_VIRTUAL, REGISTER_CONVERT_TO_RAW): Float regs
3921 are now 10 byte extendeds, not 8 byte doubles.
3922 (FRAME_CHAIN_VALID): Make this config-dependent, since it differs
3923 for nindy versus vxworks targets. FIXME, this should possibly go
3924 in the target vector.
3925 (EXTRA_FRAME_INFO, INIT_EXTRA_FRAME_INFO): Cache both
3926 frame_saved_regs and arg pointer with each frame.
3927 (FRAMELESS_FUNCTION_INVOCATION): New leafproc support.
3928 (FRAME_ARGS_ADDRESS): Use cached result.
3929 (FRAME_ARGS_ADDRESS_CORRECT): New, avoids g14 guessing.
3930 (FRAME_FIND_SAVED_REGS): Change arg to subsidiary fn.
3931 (PRINT_RAMDON_SIGNAL): Call print_fault.
3932 (POP_FRAME): Now works.
3934 * tm-nindy960.h: Break this off tm-i960.h. NINDY-specific
3935 option parsing and startup; STACK_END_ADDR, FRAME_CHAIN_VALID,
3936 BREAKPOINT, and DECR_PC_AFTER_BREAK are here.
3937 (ADDITIONAL_OPTION_HANDLER): use target_load, not
3940 * tm-vxworks960.h: Break this off tm-i960.h. VxGDB specific
3941 startup; DECR_PC_AFTER_BREAK, and FRAME_CHAIN_VALID are here.
3943 * valarith.c (value_subscripted_rvalue): Avoid handling
3944 floats and doubles specially; it gave alignment errors. Lint.
3946 * valops.c (value_of_variable, value_of_this): Error if unknown
3949 * valprint.c (print_floating): Bcopy rather than pointer-deref,
3950 to avoid alignment problems.
3951 (value_print): Handle unknown value address.
3952 (cplus_val_print): Two args are ignored; remove them. Change caller.
3953 (val_print): Use unpack_long rather than pointer-deref.
3956 (unpack_long, unpack_double): Use bcopy rather than pointer-deref
3957 to avoid alignment problems.
3958 (value_being_returned): Error if return value unknown.
3959 (set_return_value): Add bogosity warning, FIXME. *
3961 * TODO: A woman's work is never done.
3963 * Makefile.dist: Distribute REMOTE_OBS into tconfig files.
3964 Separate INCLUDE_CFLAGS for use with lint. Add LINTFILES.
3965 Add ieee-float.o to OBS.
3966 * tconfig/{nindy960,vxworks68,vxworks960}: Include the desired
3967 REMOTE_OBS remote-interface files in the TDEPFILES and TM_FILE.
3968 * tconfig/i960: FIXME. Half-merge, produce warning if config'd.
3970 Changes to generalize the VxWorks RPC protocol slightly, to handle
3971 i960 as well as 68000.
3973 * vx-share/dbgRpcLib.h (VX_SOURCE_STEP): Add.
3974 * vx-share/reg.h: Produce i960 regs #ifdef I80960
3975 * vx-share/xdr_ptrace.c: Skip FPA registers if 960.
3976 * vx-share/xdr_rdb.h: Add SOURCE_STEP struct and xdr decl.
3977 * vx-share/xdr_rdb.c: Add xdr_SOURCE_STEP routine.
3978 * vx-share/xdr_regs.c: Add xdr_regs, xdr_fp_status, xdr_ext_fp
3979 for i960. Change xdr_vectors to xdr_opaques for 68k registers,
3980 so they will move in target byte order rather than network
3981 byte order (happens to be the same).
3983 Mon Feb 25 03:41:44 1991 John Gilmore (gnu at cygint.cygnus.com)
3985 * tm-convex.h (END_OF_TEXT_DEFAULT): Remove #if 0'd block.
3987 Sun Feb 24 00:55:53 1991 John Gilmore (gnu at cygint.cygnus.com)
3990 Add contribution lines to various files, showing where they
3993 * breakpoint.c (break_insn, check_break_insn_size,
3994 read_memory_nobpt): Remove to mem-break.c.
3996 * xm-*.h, param-no-tm.h, tm-29k.h, valprint.c: Change BYTE_ORDER to
3999 * tm-29k.h (STAB_REG_TO_REGNUM): Warn user if symbol table
4000 entry has bad register number. This change is not
4001 tested in this release, FIXME.
4003 * frame.h: Eliminate Frame_unknown in favor of a simple zero.
4006 * value.h: Force value's contents field to be aligned to hold
4007 at least a double or a long long (if supported). This avoids
4008 doing bcopy's in and out of the contents field.
4010 (step_1): Avoid coredump under obscure circumstances when we
4013 * symtab.h (misc_info): Add field to misc function vector for
4014 any kind of cached information the target code desires. AMD
4015 29000 uses this to avoid repeating examine_function_prologue's.
4017 * coffread.c: Lint. Remove static symfile, read_section_header.
4018 core.c (have_core_file_p): Lint: remove.
4019 expprint.c (print_subexp): Lint.
4020 infptrace.c, valops.c, valprint.c: lint.
4022 Roll in changes from vxgdb-5.0.1:
4024 * symtab.h: Comment byte order of each address class. Add
4025 LOC_LOCAL_ARG for frame-relative args (960).
4026 expread.y: Use LOC_LOCAL_ARG where LOC_ARG is used.
4027 symtab.c, symmisc.c: ditto.
4029 * infrun.c (init_wait_for_inferior): Clear stop_signal.
4031 * remote.c (remote_resume): Error if resume with a signal.
4033 * symfile.c (prim_record_misc_function): Clear misc_info.
4034 (fill_in_vptr_fieldno): Check stub type of arg.
4036 * valops.c (value_cast): Avoid looking up names of types whose
4037 name we don't know, to prevent coredump. Sun CC produces typedef
4038 rtx and the name of *rtx is zero...
4040 Mon Feb 18 21:16:25 1991 John Gilmore (gnu at cygint.cygnus.com)
4042 Roll in changes from final AMD 29000 port (Tiemann).
4044 tconfig/am29k: Add COFF_ENCAPSULATE and TARGET=TARGET_AM29K
4045 for ../include/a.out.encap.h. This might not work now that BFD
4046 is separately compiled. Instead, BFD support for encap will have
4047 to translate machine type 29k into the right COFF_MAGIC.
4049 * infcmd.c: Remove references to inferior_pid that aren't used
4050 in actual ptrace calls; use target_has_execution, etc.
4051 (have_inferior_p): Remove function.
4052 (program_info): Print target info rather than "process number";
4053 avoid gratuitous messages unless from_tty.
4054 (run_stack_dummy, finish_command): Set proceed_to_finish.
4055 infrun.c: Remove inferior_pid refs. Decl & init proceed_to_finish.
4056 main.c: Lint. Lose have_inferior_p().
4057 inferior.h (have_inferior_p): Remove, lint.
4058 (proceed_to_finish): Add flag to ask that all regs be saved
4059 by normal_stop, for the few commands that need it, speeding up
4060 serial I/O. Add comments to stop_registers.
4062 * remote-eb.c: Remove newline from breakpoint message we grep
4063 for. Never time out when running the user program.
4067 Wed Feb 13 15:34:40 1991 John Gilmore (gnu at cygint.cygnus.com)
4069 Roll in changes from vxgdb-5.0.1:
4071 * dbxread.c (read_dbx_symtab): If we encounter a "FORTRAN COMMON"
4072 symbol in its raw form, we are processing an unlinked ".o" file.
4073 See if the target environment has assigned it an address, using
4074 target_lookup_symbol (VxWorks does), and enter it into the symtab
4077 * tm-vxworks.h (FRAME_CHAIN, FRAME_CHAIN_VALID): Override usual
4078 68k versions for a simpler version that assumes zero FP at bottom.
4079 Fixes bug of truncated stack reports.
4081 * target.h (target_lookup_symbol): Define this routine's args
4082 and result, finally.
4084 * target.c (nosymbol): Default routine for target_lookup_symbol.
4085 (target_default): Default lookup_symbol and call_function too.
4086 (files_info): Only print has_all_memory warning if a non-dummy
4089 * remote-vx.c (vx_read_register, vx_convert_to_virtual,
4090 vx_convert_from_virtual): If target does not have floating point,
4091 zero register "values", and avoid doing cross-net conversions.
4092 (vx_lookup_symbol): Rename net_lookup_symbol, add to vectors.
4093 (vx_open): Rearrange code that attaches to target and reads
4094 symbols for all loaded modules, to work if some of the modules
4095 are not accessible. Add symbol_stub() and add_symbol_stub()
4096 as callbacks from catch_errors(). Allow connect attempt to be
4097 interrupted painlessly with ^C (FIXME, there are still some bugs
4098 if the interrupt happens during symbol reading.). Print
4099 final message with puts_filtered, since symbol messages are
4104 * main.c (catch_errors): Only print errstring if non-null.
4105 (command_loop): Avoid an ioctl per command to test ISATTY.
4107 * remote-vx.c (net_load): make static; avoid sophomoric msg.
4108 (vx_xfer_memory): Return correct result!
4109 (vx_files_info): Indicate whether target has float or not.
4110 (vx_lookup_symbol): Complain, not error, if target gone.
4111 (vx_open): Print "Connected" msg before disabling immediate-quit.
4112 [FIXME: lookup_symbol and vx_open changes need testing.]
4114 target.c, remote-eb.c, inftarg.c, am29k-opcode.h, target.h,
4115 tm-29k.h, tmm-vxworks68.h, symfile.c, gdb-int.texinfo: Add
4116 contributor lines and update copyrights to 1991.
4118 Changes from an attempted H-PUX host port:
4120 * infptrace.c (PT_ATTACH, PT_DETACH): Handle HP/UX, which
4121 defines PT_ATTACH and PT_DETACH but not PT_KILL.
4122 * remote-eb.c (eb_open): Misplaced endif kills sysv H/PUX.
4123 * remote-vx.c: include <sys/time.h> for HPUX.
4124 * hp300hpux-xdep.c (fetch_core_registers): Rewrite old
4125 "core_file_command" routine to BFD regime. May not work yet.
4127 Attempted port of "gdb-3.4 Van Jacobson xgdb" to modern gdb.
4129 * xgdb.c: Replace X10 version with some VJ version.
4130 (FIXME: Its copyright assignment is not on record.)
4131 * xgdb.c: Update include files to X11R4 (Xaw crud).
4132 (xgdb_display_source, create_text_widget): fix call to
4133 get_filename_and_charpos. Rewack source window stuff for X11R4
4134 (gleaned from include files, and "nm's" of binary libraries, since
4135 I had no doc available).
4136 (append_selection, append_selection_word): Disable with FIXME
4137 since R4 changed interface here.
4138 (create_buttons): Add back the old set of buttons.
4139 (xgdb_create_window): Fix call to XtInitialize (&argc not argc).
4141 * Makefile.dist (xgdb, xgdb-init.c): Update for X11R4 on Suns.
4142 Roll VERSION to 3.94 (not yet final though).
4144 Sat Feb 9 09:46:25 1991 John Gilmore (gnu at cygint.cygnus.com)
4146 * obstack.h (obstack_ptr_grow, obstack_ptr_grow_fast,
4147 obstack_int_grow, obstack_int_grow_fast): Eliminate
4148 cast on left of assignment, which gives MIPS cc fits and is
4151 * sparc-pinsn.c (print_insn): Eliminate 'set' test, subsumed by
4152 F_ALIAS. Use printf, not fprintf, when not passing a file
4154 (compare_opcodes): Check that identical instructions have
4155 identical opcodes, complain otherwise.
4157 * sparc-opcode.h (st %fsr): Fix opcode "lose" mask. This
4158 was reported by Roland McGrath.
4159 (unimp): Only match if exactly zero instruction. (Roland)
4160 (branches and traps): Generate all variations of these
4161 instructions with macros, based on a single call that defines
4162 each condition name and its binary representation.
4163 (set): Turn on alias bit, to avoid test in sparc-pinsn.c.
4165 * valprint.c (val_print_fields): Take, and use, format parameter.
4166 This means that "p/x struct" again prints the elements in the
4167 desired format. Changed callers.
4169 * stack.c (frame_info): Use filtered output, and indicate wrap
4170 points. Remove kludgy formatting designed to avoid line wrap.
4172 * utils.c (wrap_here): If the line is already full (because
4173 we had printed a long indent or long wrapped string), do an
4174 immediate newline-and-indent.
4176 * m68k-pinsn.c (print_insn_arg): Bugfix from
4177 ntmtv!thompson@ames.arc.nasa.gov (Mike Thompson): 'bkpt #0'
4178 instruction is incorrectly disassembled as bkpt #8.
4180 * dbxread.c (end_psymtab): Bugfix from Peter Schauer
4181 <pesrem@regent.e-technik.tu-muenchen.de>: If you want to set a
4182 breakpoint in a *.y file gdb will say Reading in symbols for *.y...
4183 and then will dump core (sometimes). I traced it back to an
4184 uninitialized symfile_name in psymtab_to_symtab.
4185 (const_vol_complaint): Add quotes to message.
4186 (define_symbol): Only believe line number if gcc_compiled.
4187 Avoid allocating symbol if we will not return it.
4189 Add target strata support so that newly established targets go
4190 into their right place in the target stack (e.g. a new exec file
4191 doesn't wipe out the ability to access the running process).
4193 * target.h, core.c, exec.c, inftarg.c, remote-eb.c,
4194 remote-nindy.c, remote-vx.c, remote.c, target.c: Add to_stratum
4195 and initialize it properly in all the targets.
4197 * target.h: Document strata. Change return type of push_target.
4199 * target.c (nomemory): new function for dummy memory access.
4200 (tcomplain): Rename complain, now also used in symfile.c.
4201 (push_target): Push targets within strata. New return value shows
4202 whether new target is on top of stack or not. Always keep dummy
4204 (target_files_info): Ignore dummy target.
4206 * core.c (core_open): Warn user, and skip accessing file, if the
4207 core target is not the topmost target in the stack.
4208 * remote-nindy.c (nindy_create_inferior): Avoid unpush_target, now
4211 * remote-vx.c: Remove vx_prepare_to_store from vxworks memory
4212 target_ops, it doesn't belong there since we have no regs there.
4213 Change name of target from machine => memory to clarify.
4215 Thu Feb 7 16:32:09 1991 John Gilmore (gnu at spiff.cygnus.com)
4217 * Freeze version 3.93 for release.
4219 * Makefile.dist: Handle vx-share and nindy-share subdirs
4220 properly when building gdb.tar.Z.
4222 * symtab.c: lint; add no_symtab_msg to consolidate the messages
4223 printed in various places, so I could change just one copy.
4225 * dbxread.c, coffread.c: Change references to bfd->iostream
4226 to cast to FILE *, now that BFD avoids needing types defined
4227 in other header files.
4229 Tue Feb 5 21:39:35 1991 John Gilmore (gnu at cygint.cygnus.com)
4231 * command.c, dbxread.c, expprint.c, infcmd.c, infptrace.c,
4232 infrun.c, printcmd.c, remote-nindy.c, source.c, sparc-tdep.c,
4233 sparc-xdep.c, symfile.h, symmisc.c, utils.c, valprint.c: Lint
4234 (actually gcc -Wall).
4236 * dbxread.c: Remove first_global_sym, last_global_sym, since
4237 they are never referenced.
4239 * defs.h (baud_rate): Declare.
4240 main.c: Define it, and add the -b option to set it.
4242 * gdb-int.texinfo: Add text on how to define a new host or target
4243 architecture, prompted by Per Bothner's questions about MIPS
4246 * gdb.texinfo: Document "complaints". Change doc of -q since
4247 gdb no longer prints the copyright and blurb if you specify a file
4248 name to be debugged (just like Emacs). Add doc for Nindy-specific
4249 command line flags for specifying target serial port and such.
4250 Update copyright to 1991.
4252 * gdbcore.h: Remove a large mass of now-useless crud, since BFD
4253 has taken over for us the job of ripping up executable files. The
4254 crud caused Per Bothner's port to not compile.
4256 * infrun.c (normal_stop): Avoid printing "Program exited
4257 normally" if we are in batch mode. This allows a GDB which
4258 executes a program on a target system, to behave like a Unix
4259 command (input from stdin, output to stdout, no extraneous
4262 * main.c (main): Allow additional machine-dependent command line
4263 options to be specified with the ADDITIONAL_OPTIONS,
4264 ADDITIONAL_OPTION_CASES, ADDITIONAL_OPTION_HELP, and
4265 ADDITIONAL_OPTION_HANDLER macros. Also allow machine-dependent
4266 processing to occur just before the main loop with
4267 BEFORE_MAIN_LOOP_HOOK.
4268 (main): If a "core file" argument is specified, and it is not a
4269 core file, try it as a process ID to attach.
4270 (symbol_completion_function): Attempt to cope with
4271 "show screen-" TAB, not very successfully. This needs more work,
4273 (batch_file): New function, returns whether we are reading
4274 commands from an interactive tty on stdin, or from somewhere else.
4275 Called by normal_stop since it doesn't get from_tty passed down
4276 to it like many commands do.
4278 * remote-nindy.c: Handle command line options for nindy
4280 (nindy_before_main_loop): Prompt user for tty name if they
4281 don't specify it before getting to the interactive command loop.
4283 * tm-i960.c: Add ADDITIONAL_OPTIONS, etc, to handle -O, -brk,
4284 and -r command line options. Also add hook before main loop
4285 to make it easy to specify a tty.
4287 * TODO: More things to do, one done.
4289 Mon Feb 4 23:57:39 1991 John Gilmore and Mike Tiemann (at cygint.cygnus.com)
4291 * dbxread.c: Make complaint() calls pass pointer, not struct.
4292 Add complaints about badly formatted C++ type information
4293 (const/volatile indicator, and parse errors resulting in
4294 error_type). Fix C++ virtual member fn comment.
4295 (read_struct_type): Avoid bumping pointer if we got a parse
4296 error; this prevents our walking beyond the end of a string.
4297 Terminate loop on null char as well as semicolon.
4298 (process_one_symbol): Fix the LBRAC fix so that it uses the
4299 last previous SLINE, FUN, or SO record's PC address. C++ debug
4300 symbols did not have SLINE records in a useful order compared
4301 to the LBRAC records.
4302 (define_symbol): Handle "catch" records.
4304 * symtab.c (check_stub_type): Added new complain
4305 `stub_noname_complain' and added a consistency check to
4306 keep the debugger from crashing when finishing from an
4307 exception frame. A real fix will be needed later.
4309 Sat Feb 2 10:43:05 1991 John Gilmore (gnu at cygint.cygnus.com)
4311 * infcmd.c (attach_command): Make global.
4313 * Makefile.dist (REMOTE_OBS): Make these compile by default,
4314 but make them easy to comment out. Perhaps later they should
4315 be enabled by what CPU you configure for? FIXME.
4316 (VERSION): Roll to 3.93.
4317 (pinsn.o): Remove rule for obsolete file.
4318 (dbxread.o,coffread.o,mipsread.o): Use ${srcdir} explicitly.
4320 Run down a problem that manifested by printing the wrong function
4321 name in stack traces of read_ofile_symtab. Turned out that the
4322 problem was the SunOS 4.1.1 (and previous) C compiler outputs
4323 the LBRAC symbol with an address in the *data* segment, which
4324 blew our binary search through the blocks.
4326 * dbxread.c: Use the complain() facility consistently to bitch
4327 about problems in the symbol file we are reading.
4328 (finish_block): Add code to check the nesting of the blocks;
4329 complain and Procrust them to fit if wrong.
4330 (make_blockvector): Check the order of the blocks, complain
4331 [but don't cope] if wrong.
4332 (process_one_symbol): ifndef SUN_FIXED_LBRAC_BUG, check LBRAC
4333 symbols to be sure their PC value is greater than the last SLINE
4334 (line number) symbol we've seen, complaining and adopting the
4335 SLINE PC value if wrong.
4337 * symfile.h (struct complaint, complaint_root, complain,
4338 clear_complaints): Add.
4339 * symfile.c (complain, complaint_root, clear_complaints): Add
4340 facility to deal with non-fatal complaints and to regularize their
4342 (symbol_file_add): Clear complaint counters to allow new complaints.
4343 (initialize_symfile): Add 'set complaints' and 'show complaints'.
4345 * dbxread.c (dbx_symfile_read): Remember the address and size
4346 of the string table for the main symbol file, so we won't read it
4348 (dbx_psymtab_to_symtab): Fix the check for main symbol file,
4349 to avoid reading the string table yet again. Lint.
4350 (throughout): Improve filtered output, including word wrap.
4351 (read_range_type): Improve Bothner's fix to handle other types too.
4353 * utils.c: Improve line wrap implementation. Handle unlimited
4354 width by making chars_per_line unsigned.
4355 (puts_filtered): New, easy, function.
4357 * defs.h (puts_filtered): add.
4359 * mipsread.c (compare_symbols, sort_symtab): Remove these fns,
4360 call the identical sort_symtab_syms() in symfile.c instead.
4362 * expread.y: Suggest the `file' command rather than `symbol-file'.
4364 * command.h (enum var_types): Add zinteger for seroable
4366 * command.c (do_setshow_command): Handle var_zinteger. Restructure
4367 nested if's into a switch.
4369 * breakpoint.c (bpstat_print): If bpstat "print" flag is not set,
4370 we did not stop because of a breakpoint (it must have been for
4371 some other reason, like a "stepi"), so don't print anything.
4373 * symtab.c: Include <sys/types.h> all the time. Now that BFD
4374 doesn't include <sys/types.h>, old SunOS's require it for
4377 Sat Feb 2 10:39:15 1991 Per Bothner (bothner@cs.wisc.edu)
4379 A test port of gdb-3.92.6 to the Sony NEWS.
4382 Don't normally link in remote- or vx stuff.
4383 Some of it doesn't compile, and it wastes space for 99% of the users.
4384 Remove reference to no-longer-used HAVE_VPRINTF.
4385 Fixed BFD_DEP typo to BFD_DIR.
4387 Fix cast in arg to bfd_h_getlong.
4388 Make char *prefix be const.
4389 Fix how certain range types are mapped into builtin unsigned int types.
4391 Remove 2 #includes. They cause errors (on Sony, at least),
4392 and aren't needed (they wern't in earlier versions).
4394 print_address_symbolic should never demangle labels
4395 (since it prints *assembler-level* labels).
4397 [This was superseded by the change to printcmd below.]
4400 Add some "volatile" return types to avoid warnings.
4401 If MISSING_VPRINTF add vprintf function and not just macro
4402 (since vprintf is used in printcmd.c).
4404 Unless __GNUC__, use obstack_grow instead of obstack_ptr_grow.
4405 (The latter isn't grokked by some PCC-based compilers.)
4407 [This change is in abeyance, we prefer to fix obstack_ptr_grow.]
4409 Make chunk size of dont_print_obstack 32*4 instead of default 4096.
4410 * nindy-share/coffstrip.c
4411 Added some forward declarations (otherwise, gcc complains
4412 about implicit extern redefined as static).
4414 Sun Jan 20 02:38:19 1991 John Gilmore (gnu at cygint.cygnus.com)
4416 Changes inspired by Per Bothner:
4417 * printcmd.c (print_address_symbolic): Take additional parameter
4418 specifying whether to demangle.
4419 (print_address): Pass in asm_demangle to control demangling.
4420 (print_address_demangle): New fn, takes explicit arg to control
4422 * utils.c: Add new vars demangle and asm_demangle, and let them
4424 (fputs_demangled): If !demangle, just print the argument.
4425 (fprint_symbol): If !demangle, just print raw symbol.
4426 * valprint.c (val_print): Call print_address_demangle rather than
4427 print_address, to cause demangling to depend on the global
4428 rather than assembler-level demangling setting.
4429 * WHATS.NEW, gdb.texinfo: Document.
4431 * main.c (show_command): Show all settings if no arg.
4432 (initialize_main): Make "info set" the same as naked "show".
4433 * command.c (cmd_show_list): Handle prefix commands in the
4434 list, and print the name of the setting as well as its English
4435 description and value.
4437 Allow gdb functions to specify where a line should wrap if it
4438 exceeds the size of a terminal line. Use it to make the output
4440 * utils.c (set_screen_width_command): New fn, mallocs a buffer
4441 of the right size when screen width changes.
4442 (set_screensize_command, screensize_info): Remove #if 0'd fns.
4443 (wrap_here): New fn, indicates a point in the output where we
4444 should wrap the line rather than just letting it overflow at a
4446 (fputs_filtered): Implement wrapping.
4447 (n_spaces): New fn, returns a pointer to N spaces.
4448 (print_spaces_filtered): Use n_spaces.
4449 * defs.h (n_spaces): Declare.
4450 * stack.c (print_frame_info): Wrap with 4-space indent after
4451 fn name and before filename and line number.
4452 * printcmd.c (print_frame_args): Wrap with 4-space indent
4453 before each argument name is printed.
4454 * valprint.c (value_print): Wrap with no indentation before
4456 (val_print_fields): Wrap with indentation relative to nesting
4457 level before each field name.
4458 (val_print): Wrap with nesting indentation before array elements.
4459 * command.c (do_setshow_command): Avoid extra newlines,
4460 wrap with 4-space indent around values printed, end with period.
4461 * WHATS.NEW, gdb.texinfo, gdb-int.texinfo: Document.
4463 * breakpoint.c (breakpoint_1): Implement addressprint for
4464 "info breakpoints" display. Change file name and line number
4465 format to " at file:nnn" rather than " (file line nnn)".
4466 * gdb.texinfo: Document.
4469 Fri Jan 18 07:21:25 1991 John Gilmore (gnu at cygint.cygnus.com)
4471 Frozen for gdb-3.92.6 release.
4473 README, WHATS.NEW: Update for 3.92.6 release.
4475 tconfig/{altos, i386v, i386v32, m88k, umax}: Eliminate
4476 coffread.o from configs since it is now built by default.
4477 tconfig/{3b1, altosgas, arm, convex, hp300bsd, hp300hpux,
4478 i386v-g, i386v32-g, isi, merlin, news, news1000, np1, pn,
4479 pyramid, symmetry, vax, vxworks68}: Eliminate dbxread.o
4480 from configs since it is now built by default.
4482 Makefile.dist: Update for release 3.92.6. Handle files that
4483 have been moved to ../include, ../getopt, or ../bfd. Add
4484 saber.suppress and tests directory. Add config.status to
4485 the release (it will say "none").
4487 coredep.c: Minor formatting fixes.
4489 These changes were made in early December but only checked in now:
4490 * nindy-share/Onindy.c, nindy-share/coffstrip.c,
4491 nindy-share/nindy.c: lint
4492 * nindy-share/nindy.c (ninStopWhy): Don't byteswap the
4493 register values coming back from the target; we store values
4494 in target byte order everywhere.
4496 Wed Jan 16 19:01:37 1991 John Gilmore (gnu at cygint.cygnus.com)
4498 * am29k-opcode.h, am29k-pinsn.c: Add 29050 opcodes.
4500 * valprint.c (cplus_val_print, val_print_fields): New functions,
4501 which print C++ objects. They conspire to avoid printing a
4502 virtual base class more than once, following all the twists and
4503 turns of C++ virtual base rules.
4504 (val_print): Call the above rather than do it by hand.
4506 * symfile.c (symbol_file_add): Only reset symfile_mtime for main
4507 symbol file, not for added files like shared libs. This really
4508 needs to be generalized to a timestamp per file.
4510 * core.c (cleanup_core): Avoid coredump if no core file.
4512 * config.gdb: Accept -host or -target in place of +host or
4515 * coffread.c (find_linenos): Avoid desupported BFD interface
4516 to line numbers. We still read them manually rather than using
4517 BFD's "generic" features.
4519 * gdbrc.tex, threecol.tex: Add GDB reference card and its
4521 Makefile.dist: Add refcard to OTHERS list for creating tar files.
4523 * Makefile.dist: Eliminate use of $< in explicit targets.
4525 * readline/Makefile: Use $< rather than $*.c, which does not
4526 include the VPATH in GNU Make.
4528 * tconfig/i960-bout, tconfig/i960-coff: These are identical
4529 copies of tconfig/i960, added for global configuration
4530 compatability. All i960 versions can read both coff and b.out.
4532 * tm-88k.h: Fix multiline macro that lacked \'s. Remove
4533 COFF_FORMAT and COFF_CHECK_X_ZEROES since these are now handled
4536 * TODO: Think of more things to do.
4538 Wed Jan 2 19:09:29 1991 John Gilmore (gnu at spiff.cygnus.com)
4540 tconfig/{am29k,i960,sun2*,sun3*,sun4*}: Eliminate config
4541 of sdb versus dbx debug symbols. Add kludge for 68881 80-bit to
4542 64-bit float conversion.
4544 tconfig/sun4, tconfig/sun3, xconfig/sun4, xconfig/sun3: Make
4545 equivalent to sun?os4 so global config works.
4547 Wed Jan 2 18:20:51 1991 John Gilmore (gnu at spiff.cygnus.com)
4549 Fix from Eberhard Mattes <mattes@azu.informatik.uni-stuttgart.de>
4551 * main.c: Only declare linesize once; declare pagesize not at
4552 all, since it is never used.
4553 (main): Clear newly allocated line before it is used.
4555 Fri Dec 28 00:13:42 1990 John Gilmore (gnu at cygint)
4557 Further stabilization for the Intel 960.
4559 * Makefile.dist: Parameterize the location of the "include"
4560 and "bfd" directories, as well as "getopt". Add symfile.c.
4561 Link in both dbxread and coffread. Fix up "make depend" to
4562 rewack the locations of include, bfd, and getopt in its output.
4564 * README: Document moving include files, improve some of
4567 * coffread.c: Move common code out to symfile.c. Change
4568 symbol_file_command style interface to use new *_symfile_init
4569 and *_symfile_read interface under BFD. Use BFD internal
4570 info to locate line table, symbols, etc.
4572 * core.c (core_fetch_registers): Rename to get_core_registers
4573 to avoid confusion with fetch_core_registers.
4574 (register_addr): Move to coredep.c, which is already machine
4575 dependent. This leaves core.c pretty clean of dependencies.
4577 * coredep.c (register_addr): Accept this routine from core.c.
4579 * dbxread.c: Move common code (with coffread.c, etc) into new
4580 symfile.c. Each psymtab now contains a pointer to the
4581 format-dependent function that knows how to read it in. Make
4583 (dbx_psymtab_to_symtab): Renamed from psymtab_to_symtab_2.
4584 (process_one_symbol): Add code to complain about a "compiler bug
4585 we muzzle here", if we actually see it.
4587 * eval.c (evaluate_subexp): Insert missing "break" statements
4588 in code that determines whether a variable is an lvalue in
4589 memory, register, or whatever. I detected this via a compiler
4590 bug in which it *almost* mashed out the whole switch statement.
4592 * gdb-int.texinfo: Add minor sections on configuring gdb for
4593 release, and about the README file.
4595 * infcmd.c (registers_info): Fix formatting somewhat. Still
4596 not as pretty as before, but it handles byte swapping.
4598 * remote-nindy.c: If data cache routines are interrupted while
4599 waiting for the remote end, be sure that any uninitialized cache
4600 blocks are on the free list, not on the valid list!
4602 * symfile.h: Flesh out this header file with all the various
4603 routines and variables that have been merged in from dbxread.c
4604 coffread.c, and symtab.c to symfile.c.
4606 * symfile.c: New file, containing code common to dbxread.c,
4607 coffread.c, and some code from symtab.c. All generic code for
4608 reading symbol files should be in here now.
4609 (unrecord_misc_function): Remove unused function.
4611 * symtab.h: Remove file-reading things to symfile.h.
4613 * symtab.c: Remove file-reading things to symfile.c.
4615 * tm-i960.h: Fix FRAME_CHAIN types; define PRINT_RANDOM_SIGNAL
4616 to decode i960 fault types.
4618 * target.h, remote.c, remote-eb.c, remote-vx.c, remote-nindy.c,
4619 target.c: Change type of the "resume" function from int to void,
4620 since its result was never used.
4622 Sat Dec 22 02:51:40 1990 John Gilmore (gnu at cygint)
4624 * main.c: Replace "stupid" with "caution"; you now "set caution
4627 * printcmd.c (print_scalar_formatted): Fix typo in 'g' format
4629 * infcmd.c (do_registers_info): Call val_print to deal with the
4630 byte order of the registers being printed. FIXME, this makes
4631 the formatting of the output uglier.
4633 * infcmd.c (wait_for_inferior): If PRINT_RANDOM_SIGNAL is
4634 defined, call it for signals the debugger doesn't itself use.
4635 The i960 uses this for more detailed fault information.
4637 * remote.c (remote_open): If arg is null, print help rather than
4640 * sparc-xdep.c (register_valid): Avoid declaring size, since
4641 various modules will think of various sizes depending on the
4642 architecture of their tm-file. FIXME, we need protection against
4643 actually entering one of those modules, which would clobber
4644 storage if not for the target architecture compiled into gdb.
4646 * stack.c (up_command, down_command): Always print the frame
4648 (up_silently_command, down_silently_command): New commands
4651 * i960-pinsn.c (reg), i960-tdep.c: Lint.
4653 * i960-tdep.c (i960_frame_chain_valid): Lookup_symbol now takes
4654 more parameters than it used to.
4656 * findvar.c (registers): Increase slop to 256 bytes, which should
4657 protect us against even most RISC machines with large register
4659 (locate_var_value): Move declaration inside related ifdef.
4661 * remote-nindy.c (): Use TIOCSETN rather than TIOCSETP
4662 throughout, to avoid throwing away buffered input from the board.
4663 (nindy_wait): Supply_register takes addr_of_value, not value.
4664 (i960_print_fault): Renamed from i80960_fault.
4665 (nindy_fetch_registers): Avoid have_regs stuff, just get them.
4666 (nindy_store_registers): Avoid regs_changed stuff, just stuff
4668 (nindy_create_inferior): Don't bother to write PC_REGNUM since
4669 we can set the PC in the call to proceed(). Unpush nindy_ops
4670 before pushing it on top, to avoid message to user. Eliminate
4671 commentary from Unix machines that just misleads here.
4672 (reset_command): Fix error message to suggest target command.
4674 Wed Dec 19 11:03:56 1990 John Gilmore (gnu at cygint)
4676 Release 3.92.5 as frozen.
4678 Stabilize the merged release...with help from lint, Saber C,
4681 Everywhere: Add include files needed to declare return types
4682 of functions called.
4684 * gdb.texinfo: Roland Pesch is documenting gdb, glory be!
4686 * breakpoint.h: Add undeclared breakpoint functions, and some
4687 functions for display handling since I couldn't think of a better
4690 * breakpoint.c (insert_breakpoints): Make code for disabling
4691 shared library bkpts more likely to work. It's used when we
4692 rerun a program and stop before the shared library has been
4694 (breakpoint_cond_eval, bpstat_stop_status): Pass arg as int,
4695 cast from pointer, so it squeezes through catch_errors.
4696 (bpstat_stop_status): Fix logic broken some time ago. We now
4697 always create a bpstat if the stop address matches a breakpoint,
4698 even if we don't stop there -- just like the old code used to do
4699 before I got my fingers into it (sigh).
4700 (breakpoint_1): Print "ignore count" after "stop only if"
4701 condition, since that's how it actually works.
4702 (mention): Handle watchpoints as well as breakpoints.
4703 (watch_command): use set_raw_breakpoint and mention to do most
4704 of the work (and initialize all the fields!). Only pass one
4705 arg to parse_c_expression, since that's all it takes.
4707 * command.c (not_just_help_class_command): Rename arg to args
4708 since we ignore "unused argument" warnings on vars named "args".
4709 inflow.c (child_terminal_info): ditto.
4710 infptrace.c (kill_inferior): ditto
4711 main.c (catch_errors, version_info, quit_command, pwd_command,
4712 source_command, dump_me_command, editing_info,
4713 set_history_size_command, set_history, show_history,
4715 stack.c (locals_info): ditto
4716 target.c (target_files_info): ditto
4717 valprint.c (set_input_radix, set_output_radix): ditto
4719 * core.c: Remove old variables for handling core and exec file
4720 sections (data_start, data_end, stack_start, stack_end,
4721 reg_stack_start, reg_stack_end, reg_stack_offset, text_start,
4722 text_end, exec_data_start, exec_data_end, text_offset,
4723 exec_data_offset, data_offset, stack_offset). They're
4724 superseded the more general build_section_table and
4726 (get_exec_file): Mention the `file' command.
4727 (read_memory_check): Rename to memory_error, and only call it
4728 in the case of an actual error.
4729 (read_memory, write_memory): call memory_error.
4730 (core_fetch_registers): Register section name is ".reg".
4732 coredep.c: Remove a bunch of crud now that all this file does
4733 is pull the registers out of a core file.
4734 (fetch_core_registers): Rewrite to actually work, I hope.
4736 dbxread.c: Use a.out.gnu.h, not system a.out, now.
4737 Replace index() with strchr(). Remove all the pre-BFD macro
4738 definitions for accessing the symbol file.
4739 (struct dbx_symfile_info): Encapsulate the information that
4740 dbx_symfile_init needs to pass to dbx_symfile_read in this
4743 (dbx_new_init, dbx_symfile_init, dbx_symfile_read,
4744 dbx_symfile_discard): Rearrange symbol file reading to divide
4745 the format-specific part from the format-independent part,
4746 leaving the format-independent part such as file name expansion
4747 and opening in symtab.c. This replaces
4748 partial_symbol_file_open and partial_symbol_file_read.
4749 Symbol_file_read, add_file, add_file_target_command,
4750 add_file_addr_command move to symtab.c. Pass an explicit
4751 "mainline" flag for when reading the main symbol table, rather
4752 than relying on the offset address to be zero or nonzero.
4754 (dbx_symfile_read): Don't allow void *'s to be printed as
4756 (SWAP_SYMBOL): Use bfd routines to byte-swap the symbols.
4757 (ADD_PSYMBOL_TO_LIST): Make the "function call rather than
4758 macro" debug version really work.
4759 (read_dbx_symtab): Remove unref'd parameter inclink.
4760 Avoid swapping N_SLINE symbols, for speed.
4761 Merge N_TEXT!N_EXT case with the other external symbol
4762 definitions' case. Add comments.
4763 (start_psymtab): Allocate the symfile name in the psymtab on
4764 the psymbol_obstack, rather than using the caller's storage.
4765 (end_psymtab): Only allocate a dependencies list if there are
4767 (psymtab_to_symtab_2): Use BFD when reopening file to read
4768 its symbols for real.
4769 (read_struct_type): Add FIXME comments where it needs work
4771 (read_huge_number): Add FIXME about overflows.
4772 (read_range_type): Add FIXME about comparing a long to 1<<32.
4774 * coffread.c: Minor changes to move things closer to the new
4775 regime with symtab.c and dbxread.c Major work is still needed
4778 * exec.c (exec_file_command): Remove old variables (see core.c
4780 (xfer_memory): If memory transfer is right at the end of a
4781 section, don't lose.
4783 * findvar.c (get_saved_register): If value is in a real
4784 register, LVAL is lval_register, not lval_memory.
4786 frame.h: Declare print_sel_frame and record_selected_frame.
4788 gdb-int.texinfo: New file, for GDB internals documentation.
4789 Very simple, unformatted doc of cleanups is there for now.
4791 gdbcore.h: Remove obsolete variables that described a.out
4792 section addresses and offsets. (See core.c above.)
4793 Declare fetch_core_registers and registers_fetched.
4795 getopt.c: Declare char *alloca(); even on SPARC.
4797 infcmd.c (run_command): Call target_kill rather than
4799 (step_command, next_command, stepi_command, nexti_command):
4800 Declare from_tty parameter even though we don't use it.
4801 (run_stack_dummy): argument BUFFER is a char array, not
4802 a pointer to REGISTER_TYPE.
4803 (finish_command): using_struct_return needed a value *,
4804 not a struct symbol *.
4806 * infptrace.c (child_xfer_memory): To avoid dependency on
4807 where sections are in memory, try PT_WRITE_D and if that fails,
4808 try PT_WRITE_I. Most Unixes don't care which you use.
4810 * infrun.c (step_resume_break_shadow): Change to array to
4811 match other breakpoint shadow storage.
4812 (clear_proceed_status): Pass address of bpstat to
4813 bpstat_clear, not the bpstat itself.
4814 (child_create_inferior): FIXME comment about if the child
4816 (start_inferior): Remove old function.
4817 (child_open): Use target_kill rather than kill_inferior.
4818 (wait_for_inferior): Ditto.
4819 (insert_step_breakpoint, remote_step_breakpoint): Use
4820 new step_resume_break_shadow.
4822 * inftarg.c (child_wait): If all child processes die,
4823 pretend that the one being waited for exited with signal 42.
4825 * main.c (command_line_input): When scanning for comments,
4826 don't coredump on unclosed quotes.
4827 (quit_command): Use target_kill rther than kill_inferior.
4828 (_initialize_main): Rename class_user from "user" to
4831 * printcmd.c (print_command_1): Initialize "fmt" if no format
4832 is specified by the user.
4833 (print_frame_args): Only add to args_printed if we are
4834 actually fetching args from the stack (avoiding undefined
4836 (_initialize_printcmd): Remove bogus \{ from string.
4838 * remote-eb.c (eb_open): Avoid coredump on no argument.
4840 * remote-nindy.c: Bring out of Intel environment into new
4841 target environment. Remove all conditional compilation on
4842 I80960. Massive hacking throughout.
4843 (nindy_xfer_inferior_memory): New routine stolen from
4845 (nindy_create_inferior): New routine pieced together, probably
4846 not quite working yet.
4847 (nindy_ops): New target_ops struct for nindy.
4849 * remote-vx.c: Use write_memory rather than target_write_memory
4850 to get error checking.
4851 (vx_add_file_command, vx_open): Use symbol_file_add rather than
4853 (vx_create_inferior): Use target_terminal_ours...
4855 * signame.c (_initialize_signame): Always initialize, since
4856 we need the table for things other than psignal.
4858 * solib.c (solib_add): Use symbol_file_add, not add_file.
4859 (solib_address): Return boolean result rather than struct
4860 pointer which nobody else knows the type of.
4862 * sparc-tdep.c, valops.c: Use write_memory rather than
4863 target_write_memory, to get error checking.
4865 * stack.c (locals_info, catch_info, args_info,
4866 get_selected_block, frame_command, up_command): Use
4867 target_has_stack, rather than have_inferior_p or
4870 * sun3-xdep.c (fetch_core_registers): Rewrite for new BFD regime.
4872 * symfile.h: New file, defining the interface between the
4873 generic and object-file-specific symbol reading code.
4875 * symtab.c: Move generic symbol-reading interface to symtab.c,
4876 from dbxread.c, coffread.c, mipsread.c, etc. Add symtab_fns
4877 table to map BFD targets to symbol-reading modules in GDB.
4878 Change index to strchr.
4879 (lookup_struct_elt_type): Use error() rather than hand-made
4880 simulations thereof.
4881 (lookup_partial_symbol): Speedup slightly when length == 0.
4882 (symbol_file_add): New function.
4883 (symbol_file_command): Call it.
4884 (symfile_open, symfile_init): New function.
4885 (add_file_target_command, add_file_addr_command): moved from
4888 * target.c (target_command): use target_kill.
4890 * target.h (target_files_info): Don't declare, never called
4893 * tm-sun2.h, tm-sun3.h (STACK_END_ADDR): Use system include
4894 files to determine stack end address.
4896 * valarith.c (value_x_binop, value_x_unop): Change error message
4897 to be more useful. Pass proper argument to value_struct_elt.
4899 * valops.c (value_assign): FIXME comment that long long
4900 bitfields will break here.
4902 * Makefile.dist: Add symfile.h, remote-nindy.c, remote-eb.c.
4903 Update `make saber_gdb' to work better.
4905 * TODO: A woman's work is never done.
4907 * cplus-dem.c, environ.c, inferior.h, infrun.c, inftarg.c,
4908 main.c, obstack.c, printcmd.c, remote-eb.c, remote-nindy.c,
4909 remote-vx.c, remote.c, solib.c, source.c, sparc-pinsn.c,
4910 sparc-tdep.c, sparc-xdep.c, symmisc.c, symtab.c, symtab.h
4911 target.c, terminal.h, tm-sparc.h, tm-sunos.h, utils.c,
4912 valops.c, valprint.c, exec.c: Lint.
4915 Wed Dec 12 23:44:15 1990 John Gilmore (gnu at cygnus.com)
4917 Continuing Intel 960 port merge of GDB.
4919 * Makefile.dist: Merge i960 "nindy-share" files. Rename
4920 malloc.h to gmalloc.h to avoid name conflicts in /usr/include.
4921 Don't ship gdb.dvi in tar file. Link gdb with init.o, not init.c.
4922 Wack over "make depend" so it handles files in subdirectories
4923 vx-share, nindy-share, bfd, and in the current directory.
4925 * blockframe.c (get_prev_frame_info): Remove fatal error
4926 if stack not defined.
4928 * core.c (core_open, core_detach): New functions that handle
4929 the old "core-file" command as "target core" and "detach" instead.
4930 (core_file_command): Call them.
4931 (core_xfer_memory): Use common routine xfer_memory.
4933 * dbxread.c: Include a.out.gnu.h, not system a.out.h.
4934 dbxread now uses bfd for everything but symbol reading itself.
4935 BFD internals are used to drag out the relevant file offsets.
4936 (partial_symbol_file_open): Change args all around for BFD.
4938 * symtab.c: Rename "value" to "val" everywhere, so we can
4940 (symbol_file_command): New command, moved from dbxread.c
4941 and coffread.c. It uses BFD to read the file, then vectors
4942 based on its type, to dbx or coff symbol readers.
4943 * symtab.h: Extern a few vars for symbol_file_command.
4945 * target.h: Breakpoint takes a char * save area, not a char **.
4947 * valprint.c (val_print): When unpacking bitfields, offset
4948 the address in gdb of the value, if it is declared with a shorter
4949 type. Remove the last "runtime kludge test" of host byte order.
4951 * utils.c: Remove old my_bfd_read routine.
4953 * stack.c (frame_info): Use target_has_stack. Print program counter
4954 register's actual name rather than "pc", since it's called the
4955 "ip" (instruction pointer) on the i960 (sigh).
4957 * target.c (target_command): Add command for selecting a target
4958 type and calling its open routine. This is used for initiating
4959 communication with a particular target, in a generic way.
4961 * tm-i960.h: Update for modern gdb. Remove semicolons from
4962 various macros. Handle reading struct return convention, and
4963 error-out attempts to return structs with the "return" command.
4964 Be sure gdb doesn't think we know how to call functions in the
4967 * i960-tdep.c: Rename FRAME_CHAIN_VALID and FRAME_FIND_SAVED_REGS
4968 to i960_xxx in lower case.
4969 (arg_address): Circumvent errors due to LOC_ARG_BLOCK
4970 not being defined yet.
4972 * remote.c (remote_open): Call start_remote to initialize
4973 wait_for_inferior during open.
4974 (remote_xfer_inferior_memory): Return length written rather
4977 * remote-vx.c (target_command -> vx_open): Use new generic
4979 * remote-eb.c, inftarg.c, exec.c: ditto.
4981 * infrun.c: Fix comments.
4982 (attach_program -> child_open): Use new generic target command.
4983 (wait_for_inferior): Clear saved register values before target_wait,
4984 so target_wait can set some of them if convenient.
4986 * infptrace.c (fetch_inferior_registers, store_inferior_registers):
4987 Return success indicator, not void.
4988 (child_xfer_memory): Avoid fetching initial word if we'll
4989 overwrite it anyway.
4991 * infcmd.c (attach_command): Use new generic target open routine.
4992 (_initialize_infcmd): Update doc on attach and detach commands.
4993 (do_registers_info): Merge in a byte-order problem as a FIXME
4996 * findvar.c (find_saved_register): Avoid problem in current frame.
4997 (read_relative_register): Ditto.
4998 (write_register): Convert byte order on the way out.
5000 * exec.c (file_command): Add.
5001 (add_to_section_table, exec_command): Use new bfd_map_over_sections.
5002 (xfer_memory): Common function between core_xfer_memory and
5004 (exec_xfer_memory): Use it.
5006 * pn-opcode.h: Document that a "PN" is a Gould PowerNode.
5008 * breakpoint.c, breakpoint.h, symtab.h, value.h, frame.h, utils.c,
5009 valops.c, stack.c, target.c, sparc-xdep.c, source.c, printcmd.c,
5010 infcmd.c, i960-pinsn.c, eval.c, defs.h: lint and gcc -Wall.
5012 Sun Dec 2 16:45:06 1990 John Gilmore (gnu at cygnus.com)
5014 Merge Intel 960 port of gdb, continuing...
5016 * dbxread.c (partial_symbol_file_open, partial_symbol_file_read,
5017 symbol_file_command): Pass from_tty arg to hush 'em up.
5019 * coffread.c (symbol_file_command): Avoid output if from_tty != 1.
5020 Add magic numbers for 960 COFF format.
5022 Fri Nov 30 09:18:20 1990 John Gilmore (gnu at cygnus.com)
5024 Merge Intel 960 port of gdb, from Intel "1.2" release.
5026 CHANGE_LOG entries from their port, which was based on
5029 Thu Sep 6 11:02:22 PDT 1990
5030 Remove temp file if download is interrupted.
5032 Wed Aug 1 09:08:33 PDT 1990
5033 Now uses binary protocol to talk to NINDY.
5034 Old hex protocol (NINDY 2.13 and older) supported with -O switch.
5035 Times out after 5 seconds when trying to talk to NINDY.
5037 Tue May 29 12:54:49 PDT 1990
5038 Added variable baud rate (-b switch).
5039 Source code reorganization.
5041 Thu Apr 26 11:09:55 PDT 1990
5042 More cleanup of batch mode; specifically, execute "-s", "-e", and
5043 "-se" switches as soon as they are encountered on the invocation line.
5045 Fri Apr 20 13:47:15 PDT 1990
5048 Thu Apr 19 09:54:28 PDT 1990
5049 Add 'reset' command.
5051 Wed Apr 18 09:48:07 PDT 1990
5052 After opening remote tty, wait for 1 second to go by without input
5053 from it before trying to talk to NINDY (fixes problems with the
5054 Heurikon HK80/V960E).
5056 Mon Apr 4 16:33:05 PDT 1990
5057 Some output was not being suppressed in 'batch' mode.
5059 Thu Mar 22 15:31:11 PST 1990
5060 Ask user if old symbol table should be deleted when new file is
5063 Allow user to run a program downloaded before gdb960 was brought up.
5065 Correct "exec-file" help message for i80960 context.
5067 Correct bug in calculating user space address: could occasionally
5068 corrupt user program.
5070 Make sure to zero low-order bits in rip's because of bug in 960CA
5071 A-step part: could cause operation faults when "next"ing across
5074 Correct bug that made it impossible to get source line numbers for
5075 code loaded at addresses higher than 0x7fffffff.
5077 Wed Jan 10 12:43:22 PST 1990
5078 Open remote tty for exclusive use.
5080 Fri Jan 5 12:14:42 PST 1990
5081 Correct disassembly (CA manual was right after all):
5082 opcode for sysctl is 0x659
5084 Mon Oct 23 12:03:04 PDT 1989
5085 Use G960BASE and G960BIN environment variables to find 'sx' utility.
5087 Mon Oct 16 14:15:09 PDT 1989
5088 "sfr0"-"sfr31" should have been named "sf0"-"sf31"
5090 Mon Oct 2 15:56:31 PDT 1989
5092 Added 960CA disassembly support.
5094 To simplify maintenance:
5095 - eliminated use of symblic links on pinsn.c: use i960-pinsn.c
5097 - eliminated opcode.h: incorporates tables into i960-pinsn.c
5098 - moved 960-specific routines from i960-pinsn.c to i960-md.c
5099 - made disassembly interface identical to that in gdmp960.
5103 Wed Nov 28 21:32:48 1990 John Gilmore (gnu at cygint)
5105 * target.h: Allow targets to stack. Add target_has_memory,
5106 _registers, etc. Restructure memory access and "info files"
5107 to walk the target stack.
5108 * exec.c, core.c, inftarg.c, remote.c, remote-vx.c, remote-eb.c,
5109 target.c: Change tables to match target.h.
5110 * inflow.c (child_mourn_inferior): pop child_ops.
5111 (generic_mourn_inferior): Use new has_stack flag.
5112 * infptrace.c (child_xfer_memory): New memory regime.
5113 * inftarg.c (child_files_info): New "info files" regime.
5114 * remote-eb.c: New memory regime, new info files.
5115 * remote-vx.c: New memory regime, new info files. Now use
5116 separate targets for VxWorks attachment to machine, and
5117 actually running a process under VxWorks, since one has
5118 stack & execution & regs and the other doesn't.
5119 * remote.c: New memory regime, new info files.
5120 * sparc-xdep.c (fetch_core-registers): New memory regime.
5121 * target.c: New routines and support for stacked targets,
5122 new memory regime, new info files regime.
5125 Generalize section handling for an arbitrary number of sections,
5126 including use of the new BFD (binary file) library.
5127 * gdbcore.h: Add struct section_table.
5128 * exec.c (build_section_table): Iterate all sections and
5129 record what gdb needs to know about them.
5130 (exec_command): Use it.
5131 (exec_xfer_memory): Use the table.
5132 (exec_files_info): Print the table.
5133 * core.c (core_file_command, core_xfer_memory, core_files_info):
5135 * source.c (find_source_lines): Use bfd_get_mtime.
5136 * dbxread.c: Quick changes to make it compile with new BFD.
5137 * utils.c (error): Avoid using bfd_error in generic routines.
5139 * core.c (core_fetch_registers): Get from the ".regs" section of
5141 * sparc-xdep.c (fetch_core_registers): Use the .regs info.
5143 * inferior.h (attach_flag): Export.
5144 * infcmd.c (run_command): use new target_create_inferior.
5145 * infrun.c (child_create_inferior): Don't return result.
5146 * Makefile.dist (VERSION): 3.91.4.
5148 Fri Nov 23 28:15:38 1990 John Gilmore (gnu at cygint)
5150 * breakpoint.c (bpstat_num): Handle breakpoints which have
5151 since been deleted, such as temporary breakpoints.
5152 infcmd.c (program_info): ditto.
5154 * core.c (core_file_command): Display the frame where the core
5159 * remote-vx.c (target_command): Merge in target command from
5160 targ-vx.c. A few other cleanups.
5162 * TODO, Projects: Lots more stuff to do...
5164 Fri Nov 23 18:15:38 1990 John Gilmore (gnu at cygint)
5166 Massive changes to wall off the remote-debugging interface
5167 behind a function vector. The port to handle VxWorks targets
5168 is also part of this.
5170 All files: Replace references to renamed functions,
5171 remove references to remote_debugging, remove references to
5172 have_include_file, have_core_file in favor of target_has_stack,
5173 target_has_memory, etc.
5175 * Modularize the breakpoint interface.
5176 breakpoint.h (BREAKPOINT_MAX): New define sets max length of
5177 a breakpoint instruction.
5178 breakpoint.c: struct breakpoint's shadow_contents now sized as
5180 (insert_breakpoints): Vector to target to install breakpoints.
5181 (remove_breakpoints): Vector to target here too.
5182 Remove REMOTE_SA_SPARC kludges and other remote_debugging.
5183 sparc-tdep.c (single_step): Use new breakpoint interface for
5184 the single-step breakpoints.
5185 mem-break.c (memory_insert_breakpoint, memory_remove_breakpoint):
5186 New file, contains routines to insert and remove breakpoints by
5187 reading out the old contents and later replacing them. This is
5188 how ptrace breakpoints work, and many remote systems as well.
5190 * tm-vxworks68.h: New config file, overrides a few things for
5191 Wind River's preferences.
5193 * target.h: New file, for transfer vector used to talk to the
5194 inferior (child, attached, core, exec, remote, etc). All accesses
5195 to the thing being debugged should come through these vectors.
5196 target.c: New file, routines to handle transfer vector.
5197 (various files): Add transfer vectors XXX_ops for the various
5198 targets and pseudo-targets (core files, etc) we support.
5200 * breakpoint.c (bpstat_stop_status): Further explorations of
5201 watchpoints and why things don't work all the time.
5202 (bpstat_alloc): New fn to allocate a bpstat and chain it.
5204 * config.gdb: Only add "source ${srcdir}/.gdbinit" to
5205 the local gdbinit if it doesn't already have it.
5207 * core.c (core_ops): add and install.
5208 Allow core debugging without exec file.
5210 * dbxread.c (free_and_init_header_files): Merge two fns.
5211 (end_symtab): Free named symbol table when a new version comes in.
5212 (read_dbx_symtab): Relocate all kinds of symbols with base
5213 address. First step toward handling different text, data, bss
5215 (add_file_addr_command): Renamed add_file_command.
5216 (add_file_command): Vector to remote handler.
5217 Add "load" as an alias for "add-file" command.
5219 * defs.h: Allow "volatile" to be used in non-ANSI; use it for
5220 non-returning functions.
5222 * exec.c: Add exec_ops, and push it as a target when an exec
5225 * infcmd.c (run_command): Pass executable file name and arg list
5226 separately when starting an inferior. Permit "run" when no exec
5227 file is specified, for VxWorks.
5228 (detach_command): Move to child_detach in inftarg.c.
5230 * inftarg.c: New file. Unix-child-specific routines, and the
5231 child_ops structure.
5233 * inferior.h (registers): Export "registers" as the way for
5234 target dependent register handlers to find gdb's local copy of
5235 the registers. Rename "stop_after_attach" to "stop_soon_quietly"
5236 since it is now used by places that want wait_for_inferior to
5237 handle the grunge but want to see every trap from the inferior.
5239 * inflow.c (create_inferior): Pull out, and merge into infrun.c.
5240 Eliminate remote_debugging hooks in terminal handling.
5242 * infrun.c: Replace start_inferior with child_create_inferior.
5243 Move all the hair of Unix shells and ptrace idiosyncracies into
5244 child_create_inferior, so remote handlers don't have to deal.
5245 Remove running_in_shell. Rename stop_after_attach to
5246 stop_soon_quietly, and use it in a few other places where we want
5247 to just call wait_for_inferior and get control back on the first
5248 trap. trap_expected now never takes a value > 1.
5249 (init_wait_for_inferior): Initialize static vars when a new
5252 main.c (gdbinit): Add new hook for .gdbinit file name, let
5253 it be overridden by config files as GDBINIT_FILENAME.
5254 (DEFAULT_PROMPT): Add new hook for overriding (gdb) prompt.
5255 Both of these are used for VxWorks gdb.
5257 mcheck.c: rename include file "gmalloc.c" to avoid problems
5258 with system include file "malloc.c".
5260 param-no-tm.h: New include file, same as param.h but does not
5261 include the default "tm.h" file. This is used in files where
5262 the target is known, e.g. remote-eb.c or sparc-xdep.c.
5264 param.h: Now just a shell that includes tm.h and param-no-tm.h.
5266 remote-vx.c: New file, VxWorks remote debugging support. Uses
5267 RPC routines that are shared with the target system, in directory
5270 remote.c: Vectorize remote interface.
5272 source.c: Globalize source_path, and make an alias "l" for "list"
5273 since we now have the "load" command.
5275 sparc-xdep.c: Use new param-no-tm.h.
5277 symmisc.c (free_named_symtab): Add new function from Wind River.
5278 However, ifdef it out for now while we think about what it should
5281 tm-sun3.h, xm-sparc.h, xm-sun3.h, xm-symmetry.h: Move
5283 the xm- file, and change its name to CHILD_PREPARE_TO_STORE, since
5284 non-Unix-children handle this with their own code in the target
5287 Makefile.dist: Roll version to 3.92.3. Add vx-share stuff to
5288 source and target lists. Add vx-share to default list of include
5289 directories. Add new files to src and target lists: mem-break,
5290 target, inftarg, remote-eb, remote-vx, targ-vx. Be sure the
5291 ${srcdir} versions of munch and createtags are used.
5293 * valops.c (find_function_addr): Split out of call_function.
5294 (call_function_by_hand): Rename call_function; this function
5295 calls functions in the target by laboriously patching the target
5296 word-by-word with the right stack, args, regs, etc.
5299 Mon Nov 5 17:29:10 1990 John Gilmore (gnu at cygint)
5301 Handle AMD 29000 a bit better.
5303 * remote-eb.c (readchar): Mask received char log to make it readable.
5304 (remote_start): Pass arguments down to executing program.
5305 Make startaddr unsigned.
5306 infrun.c (start_inferior): Accept args, pass them to
5308 infcmd.c (run_command): Pass args down to start_inferior.
5310 * tconfig/am29k-aout, tconfig/am29k-coff: New files specifying
5311 the target object file format.
5312 tm-29k.h: Pay heed to COFF_ENCAPSULATE.
5314 * am29k-pinsn.c (print_insn): Print 0x on hex numbers in disassembly.
5315 am29k-tdep.c (examine_prologue): Better checking of function prefixes.
5317 Sun Oct 7 18:20:45 1990 John Gilmore (gnu at cygint)
5319 * Makefile.dist (VERSION): Roll version to 3.91.9 and freeze.
5320 * TODO: We did a few things, we have more to do though.
5322 * xm-sparc.h (CLEAR_DEFERRED_STORES): Define.
5323 * inflow.c (inferior_died): Clear deferred stores.
5325 * Debug problems with dummy frames and calls to the inferior.
5326 * tm-sparc.h (PUSH_DUMMY_FRAME, POP_FRAME): Move to sparc-tdep.c.

5328 (sparc_frame_find_saved_regs): Simplify and fix what we find.
5329 (sparc_push_dummy_frame): Simplify and fix what we push.
5330 (sparc_pop_frame): Slightly more hair here, deciding whether
5331 we are restoring a saved PC or returning to a return address in %i7.
5332 * sparc-xdep.c (read_inferior_registers): Debug if valid reg is read.
5334 * utils.c (xmalloc, xrealloc): Return type depends on __STDC__.
5335 * symtab.h (xmalloc): ditto, for obstack_chunk_alloc.
5336 * obstack.h (chunkfun): ditto.
5337 * defs.h (xmalloc, xrealloc): ditto
5339 * utils.c (quit): Grab the terminal from the child if necessary.
5341 * inflow.c (term_status_command): Rename to term_info, change
5344 * sparc-pinsn.c (print_insn): Disassembly prefers real instructions.
5345 (is_delayed_branch): Speed up.
5346 * sparc-opcode.h: Add ALIAS bit to aliases. Fix up opcode tables.
5347 Still missing some float ops, and needs testing.
5349 * Support for input and output radixes other than base 10
5350 * defs.h (input_radix, output_radix): Declare.
5351 * expread.y (yyparse, parse_number): Handle changes of input
5352 radix, and ambiguous names-or-numbers in radixes >10.
5353 * printcmd.c (print_scalar_formatted): Print formatted hex
5354 numbers in varying column widths.
5355 * valprint.c (val_print): Use output_format to print scalar ints.
5356 (set_input_radix, set_output_radix, set_radix): Create.
5357 (set_output_radix): Set output_format from output_radix.
5358 (_initialize_valprint): add `set radix' but leave the others off.
5360 * main.c (execute_command): Let stupid questions be turned off.
5361 (_initialize_main): Handle "set stupidity", etc.
5363 * main.c, inflow.c, inferior.h, frame.h, command.c, defs.h,
5364 sparc-pinsn.c, sparc-xdep.c, value.h, valops.c, values.c: Lint.
5366 Tue Oct 2 11:20:02 1990 John Gilmore (gnu at cygint)
5368 * TODO, Makefile.dist, ChangeLog: Freeze for 3.91.8 release.
5369 bfd stuff is still screwed up, but with some manual work, it
5372 * breakpoint.c (bpstat_do_actions): Start over if a command
5373 proceeds the inferior, since the inferior will have stopped and
5374 will need to have its new stop-actions taken care of.
5376 * dbxread.c (read_struct_type): Expression gives Sun3 4.0.3
5377 compiler fits, simplify it.
5379 * gdb.texinfo (directory command): Doc new dir command.
5380 source.c (directory_command): "dir" now puts things on the front
5381 of the path, moves dups up front, and handles multiple names
5382 on the command line, inserting each one in order. It also
5383 blows away cached line and full_filename info.
5385 * stack.c (backtrace_command): Skip "more stack frames follow"
5388 * Change #ifndef HAVE_VPRINTF to #define MISSING_VPRINTF in
5389 xm-convex.h, xm-hp300bsd.h, xm-isi.h, xm-merlin.h, xm-news.h,
5390 xm-np1.h, xm-pn.h, xm-pyr.h, xm-symmetry.h, xm-umax.h, xm-vax.h.
5391 The only odd one was Gould NP1, which had defined vprintf to
5394 * Merge Ted Goldstein <tedg@Eng.sun.com>'s changes for epoch.
5395 printcmd.c (print_command_1): Pass 'inspect' flag down as a global
5396 variable, inspect_it.
5397 valprint.c (print_string, val_print): Use the global inspect_it
5398 to indicate whether to print in Epoch style or normal style.
5400 Mon Oct 1 23:55:26 1990 John Gilmore (gnu at cygint)
5402 * printcmd.c (call_command): add an alias for the "print" command
5403 which runs expressions and doesn't print the result if void.
5404 (print_command_1): implement it.
5406 * command.c: Remove #if 0'd code. Initialize all the fields
5407 in add_cmd (). Rename do_nothing_command to
5408 not_just_help_class_command, and make it externally visible.
5409 command.h: add user_commands to struct.
5410 * main.c (define_command): Don't overload c->function with a char
5411 string as well as a function pointer.
5413 * eval.c (evaluate_subexp): Reinstall tiemann changes to
5414 calling convention of value_struct_elt () that got dropped in
5417 * tm-sparc.h (FRAME_FIND_SAVED_REGS): move to sparc-xdep.c.
5418 sparc-tdep.c (sparc_frame_find_saved_regs): ditto.
5420 * tm-sparc.h (POP_FRAME): replace some constants with defines.
5422 * sparc-xdep.c (store_inferior_registers): defer stores to regs
5423 until a good time (e.g. when we are about to run the child),
5424 saving ptrace calls.
5425 * infrun.c (proceed): handle DO_DEFERRED_STORES.
5426 * tm-sparc.h: define DO_DEFERRED_STORES.
5428 * sparc-xdep.c (store_inferior_registers): when storing float
5429 registers, don't store stack regs too. When storing the SP,
5430 however, DO store the stack regs too. This fixes a bug in which
5431 the dummy frame is not recognized when a call_function finishes,
5432 because its frame pointer (in the stack regs) was never
5434 (read_inferior_registers): Mark WIM and TBR and FPS and CPS valid
5435 even though we don't know how to read them from an inferior.
5436 valops.c (call_function): Comment about storing SP.
5438 * infrun.c (save_inferior_status): Save away the original bpstat
5439 chain so it can be restored later. Install the copied version for
5440 use by whoever saved the status. It will be blow away by
5441 restore_inferior_status, and the original chain restored. This is
5442 important for people who have pointers into the original.
5444 * breakpoint.c, command.h, copying.awk, dbxread.c, defs.h,
5445 findvar.c, frame.h, obstack.h, obstack.c, inflow.c, value.h,
5446 main.c, printcmd.c, sparc-tdep.c, symtab.c, valprint.c: lint
5449 Fri Sep 28 20:32:46 1990 John Gilmore (gnu at cygnus.com)
5451 * Makefile.dist: Roll version to 3.91.8. Add bfd.h and bfdconfig.h
5452 temporarily to the makefile. Add am29k-opcode.h and WHATS.NEW.
5453 Add stuff.c and kdb-start.c to the OTHERS list for tar files.
5455 Fri Sep 28 19:12:12 1990 John Gilmore (gnu at cygint)
5457 * Merge Mike Tiemann's multiple inheritance changes from Sun.
5458 Store the baseclasses in a type struct starting from array element
5459 0 rather than from the unusual array element 1.
5461 dbxread.c: the above.
5462 (virtual_context): Add
5463 Read new debug information about which virtual function table
5464 a virtual function is from, and store it in fn_field.fcontext.
5466 symtab.h: Add fcontextt. Fix baseclass indices. Typo in
5467 TYPE_FN_FIELD_STATIC_P.
5469 symtab.c: the above.
5470 valops.c: the above. Handle pointer casts of object *'s.
5471 (search_struct_method): Add.
5472 (value_struct_elt): First arg is now a pointer to a value, and is
5475 valprint.c: the above.
5476 values.c (value_virtual_fn_field): Add type arg. Handle
5477 offsetting to the proper object when calling virtual fns.
5479 (baseclass_addr): Add valuep arg.
5481 * README: Document the current state of BFD config (missing).
5482 * TODO, ChangeLog, Makefile.dist: Roll version.
5483 * WHATS.NEW: Add summary of changes since 3.5.
5485 Thu Sep 27 16:23:12 1990 John Gilmore (gnu at cygint)
5487 * dbxread.c (read_struct_type): Clear bit vectors whenever
5489 symtab.c (B_CLRALL): define.
5491 * tm-sparc.h (STORE_RETURN_VALUE): Avoid clobbering types by
5492 using == rather than =. Huh... This fixes the dreaded problem
5493 wherein builtin_type_int becomes TYPE_CODE_FLT.
5495 * core.c (info_files): Show the inferior pid.
5497 * config.gdb: Avoid putting "dir" command into .gdbinit. GDB
5498 already knows how to look in the source directory.
5500 * Remove psymtab hair from many places. Remove duplicated code
5501 for searching symbol tables. Hide psymtabs from most places.
5502 Make it fast to get from a psymtab to its symtab.
5504 blockframe.c (blockvector_for_pc): Remove psymtab hair.
5505 coffread.c (psymtab_to_symtab): Rename to psymtab_to_symtab2.
5506 mipsread.c (psymtab_to_symtab): Rename to psymtab_to_symtab2.
5507 dbxread.c: export psymtab_to_symtab, make it work if called N times.
5508 (psymtab_to_symtab): Rename to psymtab_to_symtab2. Initialize
5509 new symtab completely. New psymtabs get symtab pointer
5510 initialized to zero. Remove MI warning printf.
5511 symtab.h: Comments. Add psymtab to symtab pointer.
5512 (PSYMTAB_TO_SYMTAB): New macro.
5513 symtab.c: use PSYMTAB_TO_SYMTAB. Add psymtab_to_symtab and export it.
5514 source.c: use PSYMTAB_TO_SYMTAB. Remove symtab version and
5516 stack.c (backtrace_command): Avoid pre-pass to read symbols, if
5518 (print_frame_info): Avoid special-casing symbols that have not yet
5521 * source.c (open_source_file): Quick path if we have already
5522 located the source file by its full name.
5524 * symtab.c (lookup_symbol): Use find_pc_symtab rather than
5525 find_pc_psymtab. When a name is found in the misc function
5526 vector, search the symbol table for its mangled name, not the
5527 name that the user typed.
5529 * bfd.h: Fix missing comment terminators, make #endifs match.
5531 * valarith.c (value_less): Handle unsigned int comparisons.
5532 Add FIXME about pointer compares, which assume host and target
5533 pointers are the same.
5535 * command.c (do_nothing_command): lint
5536 dbxread.c: lint. Remove sort_syms. Document C++ visibility info,
5537 fix comments on debug symbol format for visibility. Actually set
5538 visibility of symbols.
5539 main.c (echo_command): lint; use <readline/history.h>.
5540 tm-sparc.h (FRAME_FIND_SAVED_REGS): lint
5541 obstack.h (_obstack_blank): Rearrange pointer math to avoid
5542 pointing past end of allocated memory; saber complains.
5543 obstack.h: Declare the external functions that we use.
5544 valarith.h: use <string.h>
5545 solib.c (solib_add): lint.
5547 Fri Sep 21 17:05:19 1990 John Gilmore (gnu at cygint)
5549 * main.c (initialize_main): Default info_verbose to off, now that
5550 symbol reading is fast.
5551 (quit_command): Avoid clobbering exec_bfd while quitting.
5553 * Initial BFD (binary file diddling library) merger:
5554 coffread.c: Change AOUTHDR to struct exe_hdr.
5556 core.c: initialize initialized data at compile time.
5557 (core_file_command): Move from coredep.c, convert to bfd.
5558 (xfer_core_file): Convert to bfd.
5559 exec.c (exec_file_command): use bfd routines.
5561 mips-tdep.c: Remove exec_file_command and friends.
5564 * coredep.c: (fetch_core_registers) Convert core_file_command to
5565 fetch_core_registers.
5566 mips-xdep.c, sparc-xdep.c, sun3-xdep.c: ditto.
5568 * utils.c: (error): Bogus crap, FIXME, to print bfd errors.
5569 (my_bfd_read): More bogosity, which I don't think we call.
5570 (program_name): Remove this atrocity asap!
5572 Wed Sep 19 13:36:41 1990 John Gilmore (gnu at cygint)
5575 values.c: allocate_repeat_value was not clearing the
5576 optimized_out field.
5577 (value_static_field): minor stylistic fix (wrong macro was used).
5578 valops.c (value_struct_elt_for_address): didn't work for C++
5581 * signame.c (_initialize_signame): Initialize signal names once.
5583 * breakpoint.h, command.c, copying.awk, defs.h, environ.c,
5584 exec.c, frame.h, infcmd.c, inferior.h, main.c, munch, sun3-xdep.c,
5585 symtab.h, tm-29k.h, valprint.c, value.h, values.c: Lint.
5587 * remote-eb.c: Support user-settable baud rates on the serial port.
5589 * tm-sun3.h (PREPARE_TO_STORE): fix typo.
5591 Fri Sep 14 13:28:29 1990 John Gilmore (gnu at cygint)
5593 * tconfig/sun3os4: Remove warning about native assembler,
5594 since it also occurs in the xconfig file.
5596 * findvar.c (registers): Allocate some slop after `registers'
5597 to prevent stray accesses from trashing the next variable.
5599 * tm-68k.h (REGISTER_BYTES): Allocate the right number of bytes
5600 on the sun-3, by changing the #ifdef from `sun3' (which is not
5601 defined by cc) to `sun'. Symptom was trashed builtin_type_XXX
5602 vars, which happened to follow `registers' in the executable.
5604 * readline/history.c (history_search): Heed gcc-2's advice
5605 and parenthesize && inside ||).
5607 * am29k-opcode.h, am29k-pinsn.c, am29k-tdep.c, remote-eb.c,
5608 tm-29k.c: Insert FSF copyright headers.
5610 * remote-eb.c: Better comments.
5612 * Makefile.dist: Update to 3.91.6.
5613 * TODO: note PREPARE_TO_STORE problem.
5615 Thu Sep 13 09:52:33 1990 Jim Kingdon (kingdon at cygint)
5617 * stack.c (frame_info): Only use FRAME_FIND_SAVED_REGS if defined.
5619 * remote.c: Wrap the whole file in #if !defined (SPECIAL_REMOTE).
5621 * infrun.c (wait_for_inferior, at end): Don't set up
5622 prev_* if the inferior no longer exists.
5624 * inferior.h (CALL_DUMMY_LOCATION): New macro, to replace
5625 CANNOT_EXECUTE_STACK.
5626 valops.c (call_function): Use it.
5628 * tm-convex.h: Add CALL_DUMMY_LENGTH for use by PC_IN_CALL_DUMMY.
5630 * inferior.h (PC_IN_CALL_DUMMY): New macro.
5631 infrun.c (wait_for_inferior, 2 places): Use it.
5633 * values.c (value_being_returned): Only use
5634 EXTRACT_STRUCT_VALUE_ADDRESS if defined.
5636 * Move PREPARE_TO_STORE from xm-sun3.h to tm-sun3.h to do the
5637 right thing for remote-eb.c.
5639 * sun3-xdep.c: Remove extraneous call to remote_store_registers.
5640 * sun386-xdep.c, hp300hpux-xdep.c, sparc-xdep.c: Ditto.
5642 * blockframe.c: Put get_frame_saved_regs inside #if !defined
5643 (FRAME_FIND_SAVED_REGS).
5645 * findvar.c ({fetch,store}_registers): Check for
5646 REMOTE_{FETCH_STORE}_REGISTER macro.
5648 * findvar.c (get_saved_register): Add argument lval and
5649 change meaning of argument addr.
5650 findvar.c: Change calls to get_saved_register to reflect
5651 new calling convention.
5652 valops.c (value_assign): Use get_saved_register instead of
5653 find_saved_register.
5655 Sun Sep 2 12:40:20 1990 Jim Kingdon (kingdon at cygint.cygnus.com)
5657 * coffread.c (read_one_sym): Make temp_aux an AUXENT, not
5658 an (uninitialized) pointer to one. Use "&" when passing it
5661 Fri Aug 31 22:57:54 1990 Jim Kingdon (kingdon at cygint.cygnus.com)
5663 * coffread.c (getfilename): Use DGUX x_offset and x_name if
5666 * coffread.c (symbol_file_command): Put semicolon after
5668 Put safe_to_init_tdesc_context in #if defined (TDESC).
5669 Put #ifdef TDESCs in 1st column for non-ANSI cpp's.
5670 coffread.c: #include <sys/stat.h>.
5671 (read_coff_symtab): Typo: in_source_files -> in_source_file.
5672 Add missing ')' in check for "lc%" and friends. Remove
5674 Declare read_one_sym() at top of file.
5675 (read_file_hdr): Put in extra #ifdefs so MC68MAGIC and
5676 MC68WRMAGIC can have the same value without causing a duplicate
5679 Thu Sep 13 15:55:36 1990 John Gilmore (gnu at cygint)
5681 * Allow a Makefile to be built without building the
5682 tm and xm file links that screw up builds in subdirectories.
5683 This is done with `config.gdb none', then you can do things
5684 like `make gdb.tar.Z'.
5685 * tconfig/none: Config file for no target system
5686 * xconfig/none: Config file for no host system
5687 * config.gdb: If no TM or XM files are called out by the
5688 host or target file, don't make links for them.
5690 * cplus-dem.c: Add documentation.
5692 * dbxread.c (read_ofile_symtab): Turn a fatal error into a
5693 simple error, so the user's gdb doesn't crash due to some object
5694 file problem (e.g. somebody is rebuilding the file out from under
5697 * printcmd.c (print_address_symbolic): demangle the symbol.
5699 * Makefile.dist (OTHERS): Remove tdesc-lib because it has
5700 Motorola copyrights in it. Make "make gdb.tar.Z" work.
5701 (alldeps.mak): sort and uniq all results from this; duplicates
5702 hose gdb.tar.Z link building. Remove RCS files from
5703 tconfig and xconfig. Add config files for sun386. Add
5704 a few odd files to OTHERS and HFILES.
5706 Mon Sep 10 21:20:24 1990 John Gilmore (gnu at cygint)
5708 * Makefile.dist: Pull solib.c to tconfig/sun?os4.
5709 Roll version number to 3.91.5. Make lint work in bindir.
5711 * README: Document cross-debugging and new file structure.
5713 * blockframe.c: Lint. Include "value.h" to declare read_register.
5714 (find_pc_partial_function): remove duplicate line.
5716 * command.h: Lint. Declare error_no_arg and dont_repeat.
5718 * tm-news.h: Remove inadvertently duplicated stuff.
5720 * mipsread.c: Remove cache_pc_function stuff, now done cleanly.
5721 Clean up usage of misc_function_type. Declare some CORE_ADDRs.
5723 * config.gdb: Allow `config.gdb host target' form. Clean
5724 up previous change that printed bogus messages when you just said
5727 * core.c: #include "command.h" for lint.
5730 * main.c: Remove some casts of enums. Lint.
5737 * printcmd.c (initialize_printcmd): Fix thinko in inspect cmd.
5739 * sparc-tdep.c (isannulled): Take instruction as parameter, don't
5740 read it from memory. This will allow us to save ptrace calls
5741 eventually. Changed caller single_step too.
5743 * sparc-xdep.c (fetch_inferior_registers): Avoid reading regs
5744 that we aren't going to use, saving many ptrace calls, especially
5745 when watchpointing or single stepping. Use some #define's for
5747 (store_inferior_registers): Ditto.
5748 (core_file_command): Use some #define's for constants.
5750 * tm-sparc.h: Add #define's for some register numbers, so we
5751 can eliminate the use of random constants in sparc-xdep.c.
5753 * stack.c (frame_command, print_frame_info, up_command,
5754 down_command) Remove frame_changed, since it
5755 causes a bug and doesn't seem to do anything useful. In some
5756 places it was used as a flag, in others as a stack level (?).
5758 * utils.c: Use MISSING_VPRINTF rather than HAVE_VPRINTF, so the
5759 default is to use the portable (vprintf) version rather than the
5761 * xm-news.h (MISSING_VPRINTF): Add.
5763 * valprint.c (val_print): Demangle fancy vtbl printouts. Lint.
5765 Sat Sep 8 00:24:12 1990 John Gilmore (gnu at cygint)
5767 * Remove stuff that forces -Bstatic linking of gdb, and warnings
5768 about linking debugged programs -Bstatic in the sun?os4 config
5769 files in tconfig and xconfig subdirectories.
5771 * main.c (main): Remove unreached exit(0) now that we exit
5774 * Create TODO file for online bug list. There are too many
5775 "little" bugs to keep track of on paper.
5777 * Change Projects file to refer to bug-gdb@cygnus.com
5778 rather than kingdon@ai.
5780 Fri Sep 7 23:35:15 1990 John Gilmore (gnu at cygint)
5782 * Makefile.dist (VERSION): 3.91.4 now.
5784 * symtab.c (init_misc_bunches): Rename from init_misc_functions.
5785 (condense_misc_bunches): Add sanity check that misc_count is
5786 the same as the number of symbols in the bunch.
5788 * coffread.c: rename init_misc_bunches. Pass an argument
5789 to condense_misc_bunches (a zero).
5791 * dbxread.c (partial_symbol_file_read): Call init_misc_bunches
5792 every time we are called; don't rely on our caller to do it.
5793 (add_file): Remove call to init_misc_bunches.
5795 * mipsread.c: Only warn, don't error, if unknown symbol types.
5796 This keeps an old gdb from falling on its face if it sees newly
5797 extended symbol info. Rename init_misc_bunches.
5799 Fri Sep 7 22:58:15 1990 John Gilmore (gnu at cygint)
5801 * Merge in changes from Per Bothner for DECstations and other
5802 MIPS stuff. The rest is Bothner speaking:
5804 The next message is a merger of Alessando Forin's mips port with
5805 mine. I've tried to use my good if biased judgment to get
5806 the best of both. It *does* need testing.
5808 Some of the changes are general, *not* mips-specific.
5811 Didn't believe in little-endian bit order.
5812 There are still inconsistencies about whether flags
5813 like BITS_BIG_ENDIAN are integer (#if ...) or
5814 boolean (#ifdef ...). I tried to paper over them.
5816 dbxread.c,coffread.c,mipsread.c,symtab.c,symtab.h:
5817 Moved some misc_function code that was common to
5818 {dbx,coff,mips}read.c to symtab.c.
5819 In the process, I think I cleaned things up a bit.
5820 At the same time, moved obsavestring and obconcat to symtab.c.
5823 Removed obsolete condense_addl_misc_bunches (use
5824 condense_misc_bunches(1) instead).
5827 Needed to include <sys/dir>, at least on DECstations.
5829 valops.c, mips-tdep.c, tm-mips.h:
5830 Added PUSH_ARGUMENTS macro to support funny argument-pushing
5831 conventions (when STACK_ALIGN is insufficient).
5832 Needed on mips, where doubles need 8-byte alignment,
5833 but ints only need 4.
5836 Removed cruft that was not being used.
5837 Merged in many fixes (most from Frank Yellin, fy@lucid.com).
5840 Print $ before register-names (I think that makes things a little
5842 Never print two instructions, even if one delays.
5843 Removed hex-disassemble set_cmd. (This is not mips-specific,
5844 so I think the argument is whether it is generally worthwhile or not.
5845 I'm inclined to think not, given how easy it is to
5846 convert between radixes in gdb.)
5849 This is basically Alessando's code.
5850 It doesn't use obstacks; I changed it to use obstacks
5851 in a few minor places where using malloc causes a
5852 memory leak. (Probably, more places could/should be changed.)
5853 I added record_misc_function where it was missing.
5854 In symbol_file_command and add_file_command, I tried
5855 to make the code consistent with more recent versions.
5856 Minor sylistic changes in parse_procedure.
5857 Make a .gdbinfo. psuedo-symbol point back to the real
5858 procedure symbol (using the isym field).
5861 This is basically from my port, but with a lot of details
5862 and a number of routines merged in from Alessando's version.
5863 I basically used my code "raw" backtrace (use heuristics
5864 from the actual code, rather than symbol table info) - though
5865 the idea is Alessandro's. I feel my code is a little cleaner
5866 here, particularly in being a little more flexible, such as being
5867 able to handle gcc-produced code (which it now can).
5868 It also doesn't do frame caching (which is not useful
5869 more recent gdb versions).
5870 I also used my code for push_/pop_dummy, more or less.
5871 I tried to incorporate AF's code for testing sigtramp
5872 while backtracing; I probably got it wrong.
5873 Added mips_print_register, which tries to scrunch as much
5874 information as possible on a screen...
5875 Removed the skip-prologue set_cmd. As with hex-disassemble (see
5876 under mips-pinsn.c), I don't see anything mips-specific here,
5877 and I don't see it being all that useful anyway.
5880 Added a $fp psuedo-reg distinct from $fp (nice for gcc).
5881 Use more register names (rather than hard-cases numbers).
5883 Thu Sep 6 18:33:15 1990 John Gilmore (gnu at cygint)
5885 * Hack up 3.90.11 changes:
5887 * Makefile.dist (depend): parameterize $(GCC).
5888 Add solib.c and solib.o.
5889 (readline): Fix vpath for both absolute or relative SRCDIR.
5891 * blockframe.c: Fix from Schaefer@asc.slb.com for shared libs.
5892 Also, let the part I didn't understand at least compile so
5893 I can test the rest. FIXME.
5895 * dbxread.c: Fix thinko using strcmp.
5896 (init_psymbol_list): declare static.
5897 (partial_symbol_file_open): Comment cleanups better, avoid
5898 cleaning up the string table since the caller will do that.
5899 Move the stat for mod time into symbol_file_command, temporarily.
5900 (There should be a mod time for each symbol file, eventually,
5901 to control its rereading. FIXME.)
5903 * infptrace.c (PT_WRITE_D): use same value as PT_WRITE_I for
5904 SunOS, which gives error for shared libs otherwise. (From
5905 Schaefer, probably FIXME needs work for portability.)
5907 * solib.c: Move #include "param.h" to work.
5908 Lowercase all the Uppercase Letters In the Messages.
5909 (find_solib): Clean up inferior_so_name for debug printouts.
5910 Allow no argument, to mean all shared libraries.
5912 * symmisc.c: include param.h to get CLEAR_SOLIB.
5914 Wed Sep 5 18:00:08 1990 John Gilmore (gnu at cygint)
5916 * Merge in Kingdon's changes from FSF: the diffs from 3.90.9
5917 to 3.90.11. ChangeLog entries below are from this.
5919 Wed Jun 13 09:17:39 1990 Jim Kingdon (kingdon at mole.ai.mit.edu)
5923 * Makefile.dist (HFILES): Add tm-sunos.h.
5925 Tue Jun 12 16:15:26 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5929 * Makefile.dist (gdb.tar.Z): Change linking of config so it works.
5931 Thu Jun 7 16:22:27 EDT 1990 Jay Fenlason (hack@ai.mit.edu)
5933 * sparc-opcode.h Added single-operand version of rett.
5935 Mon Jun 4 18:12:31 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5937 * m-sparc.h (REG_STRUCT_HAS_ADDR, STRUCT_ARG_SYM_GARBAGE):
5938 Put parens around gcc_p in expansion.
5940 Thu May 24 15:44:51 1990 Jim Kingdon (kingdon at mole.ai.mit.edu)
5942 * utils.c (lines_to_list): Return 10 if lines_per_page == 0.
5944 Wed May 23 16:36:04 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5946 * Changes for Sun shared libraries:
5947 blockframe.c (find_pc_partial_function): If a non-text symbol
5948 is found, set *address = pc - FUNCTION_START_OFFSET.
5949 breakpoint.c (insert_breakpoints) [DISABLE_UNSETTABLE_BREAK]:
5950 Disable breakpoints instead of giving an error.
5951 source.c (select_source_symtab): Initialize cs_pst.
5952 symmisc.c: Call CLEAR_SOLIB if defined.
5953 symtab.h: Make text{low,high} CORE_ADDR not int.
5954 (psymtab): New field addr.
5956 dbxread.c: Move DECLARE_FILE_HEADERS outside functions.
5957 (record_misc_function): Give correct type for N_DATA symbols.
5958 (condense_misc_bunches): do "misc_function_count = j" regardless
5960 Take code which is shared between symbol_file_command and
5961 add_file_command and put it into partial_symbol_file_{open,read}.
5962 Split add_file_command into add_file_command and add_file.
5963 Make psymtab_to_symtab read in the string table if the file
5965 Two new parameters to read_dbx_symtab and start_psymtab.
5966 tm-sunos.h: New file.
5968 Tue May 22 17:43:03 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5970 * infcmd.c: Change cont_command to continue_command and "cont"
5973 Mon May 21 14:41:41 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5975 * breakpoint.c (enable_breakpoint): Get value of watchpoint.
5977 * defs.h [sparc]: Use <alloca.h> regardless of __GNUC__.
5979 * values.c (USE_STRUCT_CONVENTION): Check for structures of
5980 size 1,2,4,8 rather than size < 8.
5982 * dbxread.c (dbx_lookup_type): Do f->length *= 2 as many times
5983 as necessary, not just once.
5985 * sparc-opcode.h: Add a bunch of new opcodes which Sun as supports.
5987 Thu May 17 15:04:09 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5989 * {t,x}m-sun386.h, sun386-xdep.c, {x,t}config/sun386
5991 * tm-news.h: Add CALL_DUMMY_*.
5993 * tm-68k.h: Remove duplicate comment at FRAME_FIND_SAVED_REGS.
5995 * config.gdb: In list_host, list_target, use ${i}, not $i.
5997 Tue May 15 21:27:12 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5999 * source.c (find_source_lines) [BROKEN_LARGE_ALLOCA]: Use xmalloc.
6001 * sparc-opcode.h: Change all store floating-point state register
6002 instructions to have the right match & lose fields.
6004 Sat May 5 12:39:18 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
6006 * Makefile.dist: Move -I${srcdir} to GLOBAL_CFLAGS and pass
6008 config.gdb: If srcdir != ., create readline directory and
6009 copy a makefile into it.
6011 * wait.h, infrun.c: Change WRETCODE to WEXITSTATUS for
6012 consistency with POSIX.
6014 * breakpoint.c (bpstat_stop_status): Disable watchpoint
6015 when we exit its exp_valid_block.
6017 Tue Sep 4 11:46:46 1990 John Gilmore (gnu at cygint)
6019 * Makefile.dist: Bump version to 3.91.3.
6021 * Clean up handling of breakpoint commands (somewhat).
6022 Prompted by Tiemann bug report "cont 10" doesn't work any more.
6024 inferior.h: Add breakpoint_proceeded to inferior status struct
6025 and globals; save it and restore it.
6026 (clear_breakpoint_commands): Cleanup, remove old #define.
6028 infrun.c (clear_proceed_status): Set breakpoint_proceeded.
6029 (save_inferior_status, restore_inferior_status): handle it also.
6030 (proceed): Remove earlier code that set breakpoint_proceeded.
6031 It is now set only in clear_proceed_status.
6032 (clear_proceed_status): Cleanup, use bpstat_clear rather
6033 than clear_breakpoint_commands. No callers need the stop_bpstat
6034 between clear_proceed_status and proceed.
6036 infcmd.c: Add breakpoint_proceeded definition and comment.
6037 (cont_command, jump_command, signal_command): Move call to
6038 clear_proceed_status right next to call to proceed.
6040 breakpoint.c (bpstat_do_actions): Avoid clobbering our
6041 caller's argument while running down the chain of breakpoints.
6042 Use new variable "breakpoint_proceeded" to determine when
6043 a command that it executes moves the inferior past the
6045 (bpstat_clear): Handle NULL argument.
6046 (bpstat_clear_actions): Avoid useless call to
6047 breakpoint_auto_delete.
6048 (delete_breakpoint): Clean up bpstat's that are pointing to
6049 the deleted breakpoint from the stop_bpstat chain.
6050 (breakpoint_auto_delete): Simplify.
6052 * Clean up handling of EOF, error on stdin, etc. This was
6053 prompted by a network problem that caused gdb to go into an
6054 infinite loop filling up its malloc'd memory.
6056 main.c (return_to_top_level): Cleanup: call bpstat_clear_actions,
6057 not clear_breakpoints_commands, which is now gone.
6058 (main): If command_loop returns (e.g. from EOF on stdin), do
6059 a quit_command (looping back to command_loop if quit_command
6060 doesn't really quit).
6061 (command_loop): check result from command_line_input and
6062 exit if it returns NULL, rather than passing the NULL to
6064 (gdb_readline): Free malloc'd result space before returning
6067 * utils.c (query): Handle C-d to mean "yes", just as if the
6068 input was not a terminal. Also avoid infinite loop if EOF
6069 occurs in mid-input-line before newline. This allows
6070 query to be used at EOF on stdin with reasonable results.
6072 * infrun.c (proceed): Set breakpoint_proceeded.
6074 * values.c (value_as_long): Avoid infinite recursion for enums.
6075 (_initialize_values): Fix typo in help msg (kingdon).
6077 * Makefile.dist (RL_LIB): Use RL_LIB_DEP for dependencies,
6078 RL_LIB for linking. This allows -lreadline for linking
6079 and nothing for dependencies, once readline is a real library.
6081 * config.gdb: Jim Kingdon: give useful error message if the
6082 host or target type is not recognized.
6084 * defs.h (alloca): SPARC <alloca.h> does not declare alloca,
6085 it just defines it. Dumb, but deal with it.
6087 * Jim Kingdon suggests:
6088 in xconfig/sun3os4, CFLAGS should be XM_CFLAGS.
6090 Wed Aug 29 18:03:27 1990 John Gilmore (gnu at cygint)
6092 * Makefile.dist (VERSION): Bump version # to 3.91.2.
6094 * Clean up Bothner's changes.
6096 * blockframe.c (clear_pc_function_cache): New function.
6097 * blockframe.c: remake cache_pc_function_* static.
6098 * dbxread.c (symbol_file_command): remove references to
6099 cache_pc_function_* variables.
6100 * dbxread.c (read_struct_type): Use VOFFSET_STATIC.
6101 * printcmd.c: Avoid kludging a global variable (addressprint)
6102 to avoid printing the address of a string twice. Instead,
6103 pass the format letter 's' down low enough that it can be seen
6104 to avoid this problem.
6105 (print_formatted): Pass format arg to value_print.
6106 (restore_addressprint): Remove function.
6107 (do_examine): Avoid hacking addressprint, cleanups and such.
6108 (print_frame_args): Add a comment to a Bothner change.
6109 * symtab.h: define VOFFSET_STATIC and use it instead of "-1".
6110 * symmisc.c (free_all_symtabs): Call clear_pc_function_cache
6111 to wipe out the values cached in blockframe.c.
6112 * symtab.c (find_method): Add comment saying how big you must
6113 allocate to be "big enough". Per being terse again.
6114 * valprint.c (val_print): Handle format letter "s" to print
6115 strings without addresses. Add comment to vtbl printing code
6116 which casts with wild abandon. Rearrange reference-printing
6118 @0xaddr: value (print w/addressprint)
6119 value (print w/~addressprint)
6120 @0xaddr (parameter lists w/addressprint)
6121 or nothing (parameter lists w/o addressprint)
6123 Tue Aug 28 10:47:18 1990 John Gilmore (gnu at cygint)
6125 * Merge more changes from Per Bothner:
6127 Gdb's handling of TYPE_CODE_REF was so counter-C++ (and otherwise
6128 annoying) that I tried to improve it. Here are my suggestions.
6130 These patches all attempt to handle TYPE_CODE_REF (as in C++) better.
6133 Do automatic de-reference when taking the address of a reference.
6135 Don't deref_ref when printing parameter lists.
6137 More attempts at treating refernences properly.
6139 In val_print, if deref_ref==0, don't print dangling " = ".
6141 Add COERCE_REF macro, which de-references an REF.
6143 * Merge changes from Per Bothner:
6145 * Fixed (Sony news)-specific configuration problems.
6146 * Fixed other problems with using vanilla pcc and libc (enum problems;
6147 assumption that vsprintf exists).
6148 * Some major speed-ups (finc_pc_partial_function now caches a match;
6149 parsing avoids duplicate symbol_lookup calls).
6150 * Changed handling of baseclasses (no longer use baseclasses field
6151 of struct type, use the first n_baseclasses fields instead).
6152 * Various minor changes/fixes, most C++-related.
6155 Cache the most previous match from find_pc_partial_function.
6156 (Save both low and high ends of matching function's pc range.)
6157 This speeds up the loop of infrun.c:wait_for_inferior quite
6158 a bit, and makes step/next commands much zippier.
6160 Added an enum->int cast (otherwise, some compilers barf).
6162 No longer set baseclass offset to 0, since multiple
6163 inheritance now mostly works.
6164 Added a number of casts, to shut up compiler warnings
6165 (after stabs where made enums, not ints).
6166 When discarding a symbol table (in symbol_file_command),
6167 must clear the cache introduced in blockframe.c.
6168 Don't convert $vtbl_ptr_type to vtbl any more.
6169 Get rid of TYPE_BASECLASEES and baseclass_vec (see also symtab.h).
6170 Mask off sign bit emitted by g++ for virtual table offset.
6171 Set voffset to -1 (not 1) for static member functions.
6173 Changed parsing/lexing of names to avoid doing symbol lookup twice
6174 (once when lexing to determine symbol class, once for real).
6175 Now only call symbol_lookup once. Fields of 'this' win especially big.
6177 Subpress printing addr twice in the case of 'x/s addr'.
6179 lookup_basetype_type is no longer used.
6180 Add find_methods as recursive helper function to decode_line_1.
6181 This allows multiple inheritance to work.
6182 Also, once one or more matches has been found, do not look in
6183 base-classes. (Baseclass methods would be overridden, anyway.)
6185 Removed baseclasses array in struct type.
6186 Instead of using baseclasses[i], use fields[i-1].
6187 Added virtual_field_bits[i] to indicate if the i'th baseclass is virtual.
6188 Changed sign convention of voffset (previous was inconsistent).
6190 Some macros (CALL_DUMMY and relatives) were missing. Put them back.
6192 Used to assume existence of vsprintf. Re-written to not need it
6193 if HAVE_VPRINTF is undefined.
6195 typecmp was too pessimistic. Made it less so.
6197 Don't print space after address.
6198 If vtable points to a misc symbol (with 0 offset), print it,
6199 since that indicates the actual class of the object.
6200 Changed ype_print_derivation_info to use new inheritance
6201 scheme (without baseclasses vector).
6203 In value_primitive_field, fixed some bugs left over from previous set of fixes.
6204 Also, changes needed because TYPE_BASECLASSES were removed.
6206 REGISTER_U_ADDR didn't work for PC. Rewrote to use an array.
6208 Tue Aug 21 20:08:54 1990 John Gilmore (gnu at cygint)
6211 If there is no path set, and the symbols don't indicate what directory
6212 a file was compiled in, look in the current directory. But either
6213 a path or a known compilation directory will prevent this.
6216 Three independent bug fixes:
6217 * Remove the #if 0 block that breaks some stuff.
6218 * SunOS 4.1 fixed the promoted-parameter-wrong-addr bug in Sun C;
6219 adapt gdb to either SunOS 4.0.* or 4.1.
6220 * MAX_OF_TYPE and MIN_OF_TYPE thinko. By tedg@sun, I think.
6223 Instantiate the class T when looking for methods in it. (Tiemann@sun)
6226 (type_print) Demangle the name being printed.
6227 (type_print_base) Handle botched demangling without coredump (tiemann).
6230 (check_stub_method): Document routine.
6231 (tiemann) fix bug for no-arg functions
6232 Avoid clobbering beyond end of malloc'd storage.
6233 Terminate the argument list properly.
6235 Sat Aug 18 01:29:59 1990 Per Bothner (bothner@cs.wisc.edu)
6237 * Changes merged by John Gilmore:
6240 In breakpoint_1, use new print_address_symbolic instead
6241 of find_pc_partial_function. (This forces use of assembler-level
6242 addresses, and avoids misleading non-mangled source-level names.)
6244 Generalize ansi argument such that -1 means skip arglist totally.
6245 Removed global variable print_ansi_qualifiers (which made
6246 code non-reentrant), in favor of extra explicit arguments
6247 to internal routines.
6249 Add new helper function print_address_symbolic.
6250 Use find_pc_misc_function instead of find_pc_partial_function
6251 (since we want assembler-level symbols here).
6253 Print unknown function as just "f (...)", not "f (...) (...)".
6254 Use new fputs_demangled explicitly.
6256 Fixed a typing violation (problem: value.h cannot be imported
6257 without renaming many variable in this file).
6258 lookup_symbol: If no matching misc_func, look for a C++-mangled name.
6259 decode_line_1: Moved forward some never-reached code.
6260 Made decode_line_2 skip function prologues correctly.
6262 fputs_filtered should not demangle by default.
6263 Add new fputs_demangled to demangle on demand..
6265 Change value_struct_elt to use value_primitive_field (using recursive
6266 utility function search_struct_field). This allows foo.bar to work
6267 for multiple inheritance (so far only for data fields).
6268 Change check_field in the same way (recursive helper function
6269 to support multiple inheritance).
6270 (Note: there are more of these problems that I haven't fixed.
6271 Any code that says TYPE_BASECLASS (t, 1) is probably wrong.)
6272 value_of_this: 'this' symbol name is now just "this", note "$this".
6274 Don't print static members.
6275 Avoid printing "members of <type>" if there are none.
6276 Simplified type_print_derivation_info by merging duplicate code.
6277 Remove useless blank lines in type_print_base (ptype command).
6279 Added declaration of new routine value_primitive_field.
6281 Added value_primitive_field which is generalized version of
6282 value_field that can handle multiple inheritance (non-zero offsets etc).
6283 Re-implemented value_field to call value_primitive_field.
6285 Fri Aug 17 23:33:44 1990 John Gilmore (gnu at cygint)
6287 * infcmd.c -- insert else to avoid 'delete env' coredump when you
6288 delete the whole environment. Karl Berry reported the bug.
6289 * source.c - fix openp to avoid //'s in filenames, which
6290 trigger an Emacs bug causing it to not be able to find files
6291 when running gdb in a window.
6292 * dbxread.c - zap the #if 0 that botches the add-file code.
6293 It seems to work a lot better without all the code commented out.
6295 Fri Jul 20 16:58:46 1990 John Gilmore (gnu at cygnus.com)
6297 * Merge Tiemann's and Ted Goldstein's changes, detailed below,
6300 Tue Jul 17 19:34:33 1990 Ted Goldstein (tedg at golem)
6302 * Makefile - added a ${CFLAGS} to a couple of entries,
6303 added remote-sa.sparc.c
6304 * added remote.sa-sparc.c, a modification of remote.c
6305 which conducts a dialog directly with the SparcStation prom.
6306 * breakpoint.c, infrun.c, sparcdep.c added
6307 remote_insert_breakpoint(), and remote_remove_breakpoint()
6308 to breakpoint.c instead of directly writing breakpoint instructions.
6309 * sparcdep.c on remote_debugging,there is no need
6310 to remove signle step breakpoint instructions.
6311 * main.c added "-epoch" flag and "int epoch_interface" to main.c
6313 * printcmd.c - epoch interface sends lisp expressions to open up
6314 epoch windows on inspection.
6315 * valprint.c - added arrayprint, and addressprint and made adding
6316 format controls easier
6317 * wait.h added a couple of undef's because we were getting
6318 complaints about WSTOPSIG and WTERMSIG begin redefined.
6321 Wed Jul 4 05:27:51 1990 Michael Tiemann (tiemann at masham)
6323 * symtab.c (decode_line_1): Add support for handling method stubs
6324 in the type information.
6326 Tue Jul 3 09:39:18 1990 Michael Tiemann (tiemann at masham)
6328 * values.c (baseclass_addr): Run loop from INDEX+1 to
6329 N_BASECLASSES; otherwise, we can still get into a loop.
6330 @@ This should be restructured to use a cleaner search strategy.
6332 Sun Jul 1 12:28:51 1990 Michael Tiemann (tiemann at masham)
6334 * dbxread.c (define_symbol,read_type): Grok GNU C++'s new
6335 abbreviation "Tt" for tags which have the same name as their
6338 Fri Jun 29 01:03:46 1990 Michael Tiemann (tiemann at masham)
6340 * symtab.c (list_symbols): add ability to set breakpoints on all
6341 the functions which match a particular regular expression.
6343 Tue Jun 26 04:26:29 1990 Michael Tiemann (tiemann at masham)
6345 * cplus-dem.c (cplus_demangle): New parameter ANSI says whether we
6346 should print ANSI qualifiers (such as `const' and `volatile').
6347 All callers changed to call with ANSI == 1, except from
6348 `check_method_stub', which uses old-style syntax.
6350 * symseg.h (struct fn_field): Remove unneccessary `args' field.
6351 * symtab.h (TYPE_FN_FIELD_ARGS): Redefined.
6353 * values.c (check_stub_method): New function.
6355 * cplus-dem.c (do_type): Handle "long long" (encoded as 'x').
6357 * dbxread.c (read_type): Handle new GNU C++ method type stubs.
6358 * valprint (type_print_base): Ditto.
6360 * symtab.c (gdb_mangle_typename): New function.
6362 Tue Jun 5 00:18:43 1990 Michael Tiemann (tiemann at gzilla)
6364 * breakpoint.c (catch_command): New function. Provides a
6365 mechanism to set breakpoints based on catch clauses.
6366 (disable_catch): Similar, but disables breakpoints on catch
6368 (delete_catch): Similar, but deleted breakpoints on catch clauses.
6370 Sun Jun 3 22:54:08 1990 Michael Tiemann (tiemann at gzilla)
6372 * blockframe.c (blockvector_for_pc): New function.
6373 * blockframe.c (block_for_pc): Changed to call
6374 `blockvector_for_pc' and get the block itself.
6376 * stack.c (catch_info): New function. Prints info about
6377 exceptions which can be caught in the current frame.
6378 * stack.c (print_frame_label_vars): New function. Similar to
6379 `print_frame_local_vars'.
6380 * stack.c (print_block_frame_labels): Prints out labels that are
6381 defined in this frame. These labels are exceptions that can be
6384 * dbxread.c: Updated to handle N_CATCH symtab types.
6386 Thu May 3 22:10:00 1990 Michael Tiemann (tiemann at teacake)
6388 * valprint.c (everywhere): TYPE_NAME (TYPE) no longer comes in the
6389 form "struct ..." for GNU C++. Don't flush any part of TYPE_NAME
6390 when printing the type.
6392 Wed May 2 22:43:04 1990 Michael Tiemann (tiemann at teacake)
6394 * valprint.c (val_print): Use `baseclass_addr' to access the
6395 baseclasses pointed to via the derived class object at VALADDR.
6397 * values.c (baseclass_addr): New function. Casts derived pointers
