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 * exec.c (exec_files_info): If `verbose' is set, show file offset
16 Wed Nov 20 18:35:56 1991 John Gilmore (gnu at cygnus.com)
18 * Remove gdb/hp-include. Support for HP a.out oddities should be
19 in BFD, not in GDB. Move gdb/hp-include/a.out.h to include/a.out.hp.h.
21 * infptrace.c, tm-sun386.h: Cashier <a.out.gnu.h>, remove refs.
23 * configure.in, xconfig, tconfig, Makefile.in, doc/gdbint.texinfo:
24 Makefile fragments for various hosts and targets now come from
25 gdb/config/mh-* and gdb/config/mt-*. This is for consistency with
28 * rs6000-pinsn.c, rs6k-opcode.h: Clean up.
29 * rs6k-opcode.def: Delete.
31 Wed Nov 20 05:04:40 1991 Fred Fish (fnf at cygnus.com)
33 * dwarfread.c: Recognize obsolete form of AT_element_list
34 attribute still used by at least one AT&T compiler, and possibly
37 Tue Nov 19 07:53:55 1991 Fred Fish (fnf at cygnus.com)
39 * dwarfread.c (enum_type, struct_type): Ignore names invented by
40 helpful compilers for anonymous structs, unions, and enums.
42 * c-exp.y, m2-exp.y: Add defines for yymaxdepth, yy_yys, and
43 yy_yyv, so multiple parsers produced by SVR4 versions of yacc
44 can coexist in the same executable without collision.
46 * symtab.h: Add declaration for lookup_template_type() to kill
47 compiler warnings about conversions from int to pointer.
49 Mon Nov 18 17:45:18 1991 Fred Fish (fnf at cygnus.com)
51 * procfs.c: Move inclusion of defs.h to before param.h, as in
52 all the other source files that include both. This is required
53 to supply some typedefs that are used in files included by param.h.
55 * m68k-tdep.c (m68k_skip_prologue): Add generic m68k support for
56 skipping function prologues, ala the other cpu families (i386,
57 mips, m88k, etc). Add the ability to skip movm and fmovm
58 instructions in the prologues. Still needs support for profile
59 (-p compiled) prologue sequences (FIXME).
61 * tm-68k.h: Change SKIP_PROLOGUE macro to use the new generic
62 m68k prologue skipping function by default.
64 * tm-altos.h, tm-isi.h: Continue to use the old definition of
67 Mon Nov 18 15:12:45 1991 John Gilmore (gnu at cygnus.com)
69 * Makefile.in: Remove tdesc stuff, and extra blanks before colons.
70 * blockframe.c: Remove tdesc-related code. Default
72 * infrun.c: Remove tdesc-related code.
73 * m88k-tdep.c (frame_chain_combine, init_frame_pc): Remove copies
74 of defaultable things.
75 * tm-m88k.h: New file, common to all Moto 88k target configs.
76 Derived from tm-delta88.h.
77 * tm-delta88.h: Use it.
78 * xm-m88k.h: Common file for 88K hosts. Remove obsolete stuff.
79 * xm-delta88.h: Use it.
80 * tm-*.h: Remove FRAME_CHAIN_COMBINE macros, since all are
82 * coffread.c: Remove tdesc stuff.
83 * tconfig/delta88, tconfig/m88k: Remove tdesc stuff.
84 * xconfig/m88k: Rename tm-88k.h to tm-m88k.h.
86 Mon Nov 18 13:51:37 1991 Per Bothner (bothner at cygnus.com)
88 * source.c (open_source_file): If openp fails, try again
89 using just the base (non-directory) part of the filename.
90 This solves various annoying problems, such as when the
91 source was compiled with an absolute pathname - and the
92 source files have moved. Or if the source was compiled
93 using a relative pathname, it can be more convenient
94 to just specific the source directory to the dir command.
96 Mon Nov 18 00:04:41 1991 Fred Fish (fnf at cygnus.com)
98 * cplus-dem.c (munge_function_name): Add missing third arg to
99 instance of call to do_type().
101 * dwarfread.c: Changes to match new dwarf.h. Remove
102 AT_deriv_list, AT_loclist, AT_incomplete, AT_const_data,
105 Sun Nov 17 16:20:53 1991 Michael Tiemann (tiemann at rtl.cygnus.com)
107 * symtab.h (struct type): Moved C++-specific fields into new type
108 `struct cplus_struct_type'. Now takes 10% less memory. Many
110 * symtab.c (init_type): Don't set fields belonging to
111 TYPE_CPLUS_SPECIFIC unless TYPE is TYPE_CODE_STRUCT.
112 * buildsym.c (read_type): Allocate TYPE_CPLUS_SPECIFIC for
114 (read_struct_type): Ditto. Also, add comments about how we can
115 deduce TYPE_VPTR_FIELDNO from inheritance info and fieldname info.
116 * coffread.c (decode_base_type): Allocate TYPE_CPLUS_SPECIFIC for
118 (read_struct_type): Ditto.
119 * dwarfread.c (struct_type): Ditto.
121 * symtab.c (read_range_type): Don't set TYPE_MAIN_VARIANT.
122 (lookup_pointer_type): Don't use or set TYPE_MAIN_VARIANT.
123 (lookup_reference_type): Ditto.
125 * cplus-dem.c: Many changes made to handle decoding of
127 * symtab.c (gdb_mangle_name): Mangle/demangle ANSI-mangled names

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

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

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

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

363 Thu Nov 7 18:26:15 1991 Steve Chamberlain (sac at rtl.cygnus.com)
365 * Makefile.in: link with libiberty after libreadline, since
366 readline might want something in libiberty.
367 * m88k-xdep.c: Fixed the register offsets in the ptrace_user
368 struct for BCS 88k machines.
369 * xm-m88k.h: don't define USIZE if already defined.

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

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

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

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

898 * valprint.c (val_print, type_print_base): TYPE_CODE_RANGE less
901 * nindy-tdep.c (nindy_frame_chain_valid): Use lookup_misc_func.
902 (Reported by Mark Peek <mark@imagen.com>.)
904 * solib.c (solib_map_sections): Relocate all sections, even
905 though only the text section's size is tracked. Mark ld_text
906 for eventual elimination as we generalize to N sections.
908 * infrun.c (wait_for_inferior): Don't check if the PC is in a
909 call_dummy if we were stopped by a random signal that is being
910 passed to the program. This produced wierd results when calling
911 functions in the inferior and signals (e.g. SIGALRM) were in use.
913 Tue Sep 24 18:05:30 1991 John Gilmore (gnu at cygnus.com)
915 * infrun.c (IN_SIGTRAMP): Not parenthesized properly.
916 Bugfix from Paul Eggert <eggert@twinsun.com>.
917 * tm-ultra3.h (IN_SIGTRAMP): Ditto.
918 * valprint.c (print_floating): Print 9 digits for IEEE floats.
921 Mon Sep 23 15:50:07 1991 John Gilmore (gnu at cygnus.com)
923 * Makefile.in: Roll VERSION to 4.1.1.
924 * source.c (line_info): Peter Schauer fixes a bug I introduced in
927 Fri Sep 20 16:10:52 1991 John Gilmore (gnu at cygnus.com)
931 * Makefile.in (VERSION): Set to 4.1.
932 * language.c (set_language_command): Print useful help message,
933 and restore the language string after giving help.
934 * valprint.c (typedef_print): Print typedef in C or M2.
935 * symtab.c (list_symbols): Use it.
936 * main.c (main): Avoid any output before (gdb) prompt when -q.
937 * language.c (set_language_command): Handle errors by restoring
938 the language string to its current state (fix from A. Beers).
939 * doc/gdbint.texinfo: Roll in information from README. Rearrange
940 "how to install" and "how to print the doc" stuff so it drops
942 * configure.in: Rename rtpc CPU to romp to match config.sub.
943 * README, WHATS.NEW, TODO: Update for gdb-4.1.
945 Fri Sep 20 17:39:14 1991 Roland H. Pesch (pesch at cygnus.com)
947 * doc/gdb.texinfo: Updates from ChangeLog. set/show write,
948 autoloading shared libs, copyright etc on GDB startup, clean up $_
949 and $__ index refs, set/show listsize and related updates to list
950 cmd. New host/target configs.
952 Fri Sep 20 15:46:00 1991 Roland H. Pesch (pesch at cygnus.com)
954 * doc/Makefile: generate aux version-no file doc/gdbVN.m4
955 from main Makefile.in version definition
956 doc/gdb.texinfo: use version recorded in doc/gdbVN.m4 for current
958 Makefile.in (setup-to-dist): generate doc/gdbVN.m4
960 * doc/gdb.texinfo: merge new language-switching and lang-specific
963 Fri Sep 20 15:00:57 1991 Per Bothner (bothner at cygnus.com)
965 * mcheck.c: Add __ONEFILE kludge to allow compilation by non-ANSI
966 compilers (which may lack stddef.h).
968 Fri Sep 20 13:29:42 1991 John Gilmore (gnu at cygnus.com)
970 * dbxread.c (read_dbx_symtab, process_one_symbol): N_FN and
971 N_WARNING are the same except for the N_EXT bit, so just use their
972 values alone, rather than OR-ing them with N_EXT.
974 Fri Sep 20 12:27:55 1991 Stu Grossman (grossman at cygnus.com)
976 * mipsread.c (parse_lines): Deal with negative extended line
979 * c-exp.y, m2-exp.y: #define yyerrflag and yynerrs to avoid
980 global symbol conflicts.
982 Fri Sep 20 02:28:15 1991 John Gilmore (gnu at cygnus.com)
984 * .gdbinit: Move 'set complaints' to top, so it runs even in
985 case we aren't debugging GDB.
986 * language.c (_initialize_language): Fix type check and range
987 check documentation strings.
988 * utils.c (!HAVE_VPRINTF): Define vfprintf as a function, so
989 language.c can use it. (Though language.c should really not be
990 handling warnings/errors the way it does, FIXME.)
991 * symtab.c (lookup_primitive_type): const lint.
993 Bugfix from Peter Schauer:
994 * source.c (lines_to_list): Make signed, to avoid comparison
995 going unsigned and complaining that -3 is too high for 21 lines.
996 * stack.c (lines_to_list): Ditto.
998 Thu Sep 19 23:33:41 1991 John Gilmore (gnu at cygnus.com)
1000 * Makefile.in (HFILES): Add minimon.h.
1001 (VERSION): Roll version number to 4.0.95.
1002 (gdb.tar.Z, make-proto-gdb.dir, setup-to-dist, gdb-XXX.tar.Z):
1003 New rules for building distributions. Normal distribution
1004 is built by doing `make -f Makefile.in gdb.tar.Z' in the directory
1005 one level up from here; it calls make-proto-gdb.dir to build a
1006 directory `proto-gdb' which is an image of the release. The old
1007 `gdb.tar.Z' rule still works too.
1008 * config.sub, configure: Roll in latest from ..
1010 Thu Sep 19 17:41:24 1991 Roland H. Pesch (pesch at cygnus.com)
1012 * doc/gdbint.texinfo: Reorder contents; reorganize new-host,
1013 new-target, and new-config chapters; fix minor typos; come closer
1014 to usual GNU markup conventions for @file @samp @code @var.
1016 Thu Sep 19 17:04:12 1991 Per Bothner (bothner at cygnus.com)
1018 Patches from Peter Schauer <pes@regent.e-technik.tu-muenchen.de>:
1019 * mipsread.c (parse_partial_symbols): Enter the name of all
1020 structs/unions... into the psymtab so we can access them if the
1021 symtab is not read in.
1022 * mips-tdep.c: Remove some unneeded #includes.
1023 * xconfig/dec3100: Add HAVE_STRSTR.
1025 Thu Sep 19 15:14:23 1991 John Gilmore (gnu at cygnus.com)
1027 * Makefile.in: Circumvent Sun Make bug on *-exp.tab.o.
1028 * c-exp.y, m2-exp.y: Lint.
1029 * m2-exp.y: Avoid using yytname[] which is a Bison-ism.
1030 * valprint.c (val_print_fields): Check for stub type.
1031 * mipsread.c (_initialize_mipsread): Avoid using
1032 builtin_type_void at initialize time.
1033 (mipscoff_symfile_read): use it now.
1035 Wed Sep 18 15:55:51 1991 John Gilmore (gnu at cygnus.com)
1037 Merge multiple-language support, and partial Modula-2 support,
1038 from Andrew Beers <beers@cs.buffalo.edu>.
1040 * i387-tdep.c: New file, consolidates most 80387 support,

1060 (process_coff_symbol): #if 0'd for functions and params as above.
1061 (read_enum_type): Recognize Modula-2 BOOLEAN.
1062 * symtab.c (add_param_to_type): #if 0'd function to add a

1134 Tue Sep 17 08:37:41 1991 John Gilmore (gnu at cygint.cygnus.com)
1136 Add Andrew Beers' changes for Modula-2 support. His ChangeLog
1137 entries are enclosed herein. Not all of these changes
1138 have been merged into the master GDB sources -- check the
1139 ChangeLog above here for the merge log.
1141 Mon Jun 3 17:05:45 EDT 1991
1143 m2-exp.y Created. Tested outside of GDB for a few days. Proper
1144 operators were added, C specific operators and tokens
1145 removed. yylex() revamped to some extent. Still things
1146 missing from the grammar, such as sets.
1147 Tested for two weeks in GDB v3.5.
1149 Tue Jun 11 17:23:48 EDT 1991
1151 m2-exp.y Added boolean constants TRUE and FALSE to the grammar
1152 so they are built-in. Sort of a hack.
1154 Fri Jun 14 12:53:51 EDT 1991
1156 m2-exp.y Added range checking for numeric constants. Any numeric
1157 constant is assumed to be of builtin type INTEGER unless:
1158 (1) it is octal or hexadecimal, in which case it is a
1159 CARDINAL; (2) it is too big to fit into an INTEGER, in
1160 which case it is a CARDINAL.
1161 eval.c Added simple range checking for +, -, and * on integers.
1162 Doesn't work very well for *, since 6 * 1,000,000,000 =
1163 1,705,032,704, which fails the simple test of result >=
1164 first_operand, no matter in what order the operands are.
1166 Tue Jun 18 14:11:30 EDT 1991
1168 Broke the parser into parts, one containing the C grammar and the other
1169 containing code to be shared by all of the grammars.
1171 The following files no longer exist:
1176 The following files were added:
1178 c-exp.y (The C grammar)
1179 m2-exp.y (The Modula-2 grammar)
1180 parser-code.c (Code that is shared by the above grammar)
1184 Makefile.dist Changed to reflect the above dependencies. NOTE: It is
1185 now necessary to use the Bison compiler compiler, since it
1186 will generate function/variable prefixes other than yy.
1188 Tue Jun 18 16:47:49 EDT 1991
1190 symtab.[ch] Added the external variable working_lang, than holds the
1191 value of the current working language.
1192 Added the ennumerated type language_mode, with the values
1193 language_auto and language_manual, the former meaning that
1194 GDB sets working_lang as needed, and the latter meaning
1195 that the value of working_lang is totally under user
1197 symtab.[ch] Added the Modula-2 pervasive types INTEGER, CARDINAL,
1198 REAL, BOOLEAN and CHAR. Also added the type codes
1199 TYPE_CODE_BOOL and TYPE_CODE_CHAR.
1200 utils.c Added set_language_command and show_language_command to
1201 implement the GDB support commands "set language" and
1203 expression.h A number of identifiers were added to the type exp_opcode
1204 to facilitate Modula-2 builtin functions, integer
1205 division, and array indexing.
1207 Wed Jun 19 13:25:58 EDT 1991
1209 language.h Added the macro STRICT_TYPE, which evaluates to non-zero
1210 if the language specified by working_lang requires the use
1211 of strict typing of expressions. Eventually, even this
1212 will be able to be changed by the user.
1213 Added the macro RANGE_CHECK, which evaluates to non-zero
1214 if the language specified by working_lang requires the
1215 checking of a value against the domain of its type.
1216 Eventually, even this will be able to be changed by the
1218 language.[ch] Predicates involving types (simple_type, ordered_type,
1219 same_type, integral_type, numeric_type, character_type,
1220 boolean_type, float_type) are added. These predicates are
1221 based on the current value of working_lang, and are handy
1224 Wed Jun 19 15:39:34 EDT 1991
1226 eval.c Added the function type_array_rank which computes the rank
1228 valarith.c Added the funtion value_bool, which when given a integer
1229 value.h value (ie. struct value *) as an argument, it returns a
1230 boolean value (ie. struct value *) true if that integer
1231 is non-zero, and a boolean value false otherwise.
1232 valprint.c Added cases for TYPE_CODE_BOOL, so Modula-2 BOOLEAN values
1233 will print out properly.
1235 Wed Jun 19 16:36:34 EDT 1991
1237 valops.c Added the function value_capitalize, which returns it
1238 value.h argument capitalized if its argument is a lowercase
1239 letter, or the argument unchanged if its argument is not a
1241 valarith.c Added the function range_check_p, which returns non-zero
1242 value.h if its value argument is between the integral bounds upper
1244 Added the function range_check_enum_p, which makes sure
1245 that its value argument is a valid member of the domain of
1247 Added the function range_check_range_p, which makes sure
1248 its value argument lies between the upper and lower bounds
1249 of its type argument, which must be a ranged type.
1250 Added the function check_array_index, which range and type
1251 checks an index of an array.
1252 Added the function value_multi_subscript, which computes
1253 array[idx1,idx2...idxN], given a value array and an array
1254 of values representing indicies.
1255 values.c Changed value_from_long to work with TYPE_CODE_CHAR and
1256 unpack_long to work with TYPE_CODE_BOOL and
1259 Wed Jun 19 18:04:08 EDT 1991
1261 symtab.c Stored pervasive types in a structure and make
1262 lookup_pervasive_type() a lookup function that was based
1263 on working_lang. If lookup_pervasive_type() returned
1264 non-zero, then that value was returned (a fix, since
1265 before it simply wouldn't return the pervasive type.)
1266 language.h Added the macro CAST_IS_CONVERSION, which evaluates to
1267 non-zero if the language specified by working_lang means
1268 "conversion" when it says "cast".
1269 valops.c Added the function value_real_cast(), which performs a
1270 value.h *cast*, not a *conversion*, which is what value_cast()
1271 does when it can. In particular,
1272 value_cast(<float_type>,4) = 4.0, while
1273 value_real_cast(<float_type>,4) = some mess.
1274 eval.c Modula-2 builtin functions implemented: ABS, CAP, CHR,
1275 parser-code.c FLOAT, HIGH, MAX, MIN, ODD, ORD, TRUNC, and VAL.
1276 expression.h Added macros MAX_OF_TYPE and MIN_OF_TYPE to work with MAX
1277 and MIN on integral types. *NOTE*: These are currently
1278 hardcoded to work only if there are 8 bits per storage
1280 eval.c Made logical functions call value_bool to return a
1281 properly typed boolean value, based on working_lang.
1283 Thu Jun 20 11:55:27 EDT 1991
1285 valprint.c Types now print out in a Modula-2 fashion. This works for
1286 the cases when the type is printed out step-by-step, that
1287 is, it doesn't work when the name of a structured type
1288 (which includes the keyword "struct", etc.) is simply
1290 FIXME: Perhaps this is bad. Parts of it seem to kludgey,
1291 since type specifications in C and Modula-2 are very
1292 different. The C printing of a type is very recursive,
1293 whereas in Modula-2 it is generally very simple. C has
1294 type prefixes and suffixes, which have no real analogue in
1295 Modula-2. Maybe type_print() should call a language
1296 specific type printer. This is also advantageous if we
1297 compile GDB to exclude some of the languages. We'll just
1298 leave those functions out.
1300 Thu Jun 20 16:57:10 EDT 1991
1302 dbxread.c When reading the complete symbol table in (via
1303 psymtab_to_symtab()), the number and types of function
1304 arguments are added to a function type. define_symbol()
1305 calls add_param_to_type() to accomplish this.
1306 Assumption: when we come across a function definition
1307 (N_FUN symbol with an 'f' or 'F' in the name), its
1308 arguments will appear before another function definition.
1309 When a function is found, a pointer to its type is placed
1310 in the global in_function_type. Changes that
1311 add_param_to_type() makes are to this global.
1312 valprint.c The type of a function now includes (for Modula-2) the
1313 types of its parameters.
1314 eval.c Type checking and a check for the proper number of
1315 arguments is now done for function calls. Not sure of the
1316 impact this has on C++ member function yet.
1318 Thu Jun 20 19:58:48 EDT 1991
1320 valprint.c Rewrote the type printer. Broke it into two language
1321 specific parts, adding the functions type_print_m2() and
1323 An unfortunate consequence is this: if you debugging a C
1324 program in Modula-2 mode (why?), info types does not work
1325 well with regular expressions, since the types are printed
1326 out in Modula-2 terminology, but stored in C terminology.
1327 language.[ch] Added the functions new_type_last(), type_keyword(), and
1328 type_sep() to aid in the printing of typedefs.
1329 symtab.c Made the printing of typedefs as language independent as
1330 possible through calls to new_type_last(), type_keyword(),
1333 Fri Jun 21 11:50:26 EDT 1991
1335 dbxread.c Check all incoming ennumerated types. If it looks like
1336 Modula-2's BOOLEAN type, then change the type_code of the
1337 type to TYPE_CODE_BOOL so we can process it as a boolean
1339 valprint.c Replaced some of the 0x%x with calls to sprintf and
1340 hexformat() in val_print().
1341 language.[ch] Added the function hex_to_string(), which converts its
1342 integral argument to a hexadecimal number (format is
1343 language based) and returns the result as a string.
1345 Mon Jun 24 12:25:07 EDT 1991
1347 valprint.c Some functions call type_print_1() directly, instead of
1348 value.h using type_print(), so they can specify where (column) to
1349 print things. Since type_print() takes care of language
1350 dependence, that needs to be called first. Added a
1351 parameter depth to type_print() (so it is now like
1352 type_print_1). Changed type_print to type_print_at, and
1353 made type_print a macro that passes a depth argument of
1355 symmisc.c Changed all calls to type_print_1 to calls to
1357 Makefile.dist Made it possible to build GDB for a specific set of
1358 depend languages. Do this by passing a definition for the macro
1359 LANGS to make. LANGS should be a string containing a
1360 space-separated list of language names (ie. LANGS="c m2").
1361 The default is to build all languages. Note that grammar
1362 files must follow the naming convention of <lang>-exp.y.
1363 gdb.lang This holds the current value of the LANGS macro. It is
1364 examined every time make is called, and is updated if
1366 eval.c Added #ifdef _LANG_<lang> to these files.
1367 expread.c Still need to add them to dbxread.c and coffread.c.
1375 Mon Jun 24 16:33:11 EDT 1991
1377 language.[ch] Added the functions hexformat_pre() and
1378 hex_to_string_pre(), which take a prefix argument to
1379 include in the format string. Thus, hexformat_pre("08") will
1380 return "0x08x" (if the working language is language_c).
1381 Made hexformat() and hex_to_string() calls to the above
1382 with "" as the prefix argument.
1384 am29k-pinsn.c, arm-pinsn.c, breakpoint.c, convex-tdep.c, exec.c, core.c,
1385 dbxread.c, i386-pinsn.c, i386-stub.c, i386-xdep.c, i960-pinsn.c,
1386 infcmd.c, inflow.c, m68k-pinsn.c, m68k-stub.c, m88k-pinsn.c,
1387 mips-pinsn.c, mips-tdep.c, ns32k-pinsn.c, printcmd.c, pyr-pinsn.c,
1388 pyr-tdep.c, pyr-xdep.c, remote-vx.c, remote.c, solib.c, source.c,
1389 stack.c, sun386-xdep.c, symfile.c, symm-xdep.c, symmisc.c, tahoe-pinsn.c,
1390 valprint.c, vax-pinsn.c
1392 Changed all occurences of 0x%[0-9]*l*x in printf format strings to
1393 calls to hexformat() and hex_to_string(). Format strings without
1394 the leading "0x" were ignored.
1396 depend Updated to take the above into account.
1399 Tue Jun 25 15:27:18 EDT 1991
1401 symtab.h Added the types range_mode_t, range_check_t, type_mode_t,
1402 and type_check_t to keep track of the current state of
1403 range and type checking.
1404 main.c Added the variables range_mode, range_check, type_mode,
1405 and type_check to record the current state of range and
1406 type checking. Added initialization code to main().
1407 language.h Changed the macros STRICT_TYPE and RANGE_CHECK to examine
1408 the above variables.
1411 Tue Jun 25 17:57:08 EDT 1991
1413 dbxread.c process_one_symbol() updates the variable (enum language)
1414 source_lang based on the extension of the filename
1415 contained in the N_SO sybmol that started this symtab.
1416 When end_symtab() is called, the value of source_lang is
1417 put into the language field.
1418 stack.c select_frame() sets working_lang (and possibly type_check
1419 and range_check) to the language field of the symtab
1420 associated with the frame that is selected if working_mode
1421 is language_auto. If working_mode is language_manual, a
1422 warning is printed and working_lang is not set.
1423 language.c Added the function set_type_range(), which sets the value of
1424 type_check and range_check (if their modes call for
1425 automatic setting) based on the current value of
1426 working_lang. A non-zero argument will cause the current
1427 settings to be output.
1430 Wed Jun 26 14:51:40 EDT 1991
1432 eval.c Added range checks on assignment.
1433 m2-exp.y Added the grammar for sets to the language. Currently,
1434 these do not do anything except print an error message.
1436 Wed Jun 26 17:01:04 EDT 1991
1438 m2-exp.y Added the ability for parse_number() to parse negative
1439 numbers. A global flag is set upon encountering a unary
1440 minus. This was done to make, for example, 1 parse as a
1441 CARDINAL, and not as an integer, per Wirth's examples in
1442 Programming in Modula-2 ed.4.
1443 valprint.c Added support for "set radix 2" by then setting
1444 output_format to 't'.
1445 eval.c Implemented range checking on subrange types. Added calls
1446 to range_check_range_p for BINOP_ASSIGN and BINOP_VAL.
1447 Implemented MIN and MAX for ennumerated types. The
1448 minimum value of an ennumerated type is defined by Wirth
1449 as the first identifier, and the maximum as the last.
1450 m2-exp.y Made octal numbers ending with "B" be characters and those
1451 ending with "C" be numbers, per Wirth's book. (p. 34)
1453 Thu Jun 27 14:11:52 EDT 1991
1455 stack.c select_frame() now only sets working_lang, it does not
1456 notify the user. If working_mode is language_manual, then
1457 a warning is issued once.
1458 main.c At the end of each call to execute_command(), working_lang
1459 is checked against the local static (enum language)
1460 current. If they differ and working_mode is
1461 language_auto, the new settings of language, type and
1462 range checking are printed out.
1463 stack.c Modified frame_info() to include the language of the
1464 current frame in the output of "info frame".
1465 language.[ch] Added the function language_str() which returns the name
1466 of the current language.
1468 Fri Jun 28 15:33:14 EDT 1991
1470 m2-exp.y Added the built-in procedures INC, INCL, DEC, and DECL to
1471 the language. INCL and DECL currently cause an error,
1472 since sets are not implemented yet. INC and DEC are
1473 implemented as PREINCREMENT/PREDECREMENT with one
1474 argument, and as ASSIGN_MODIFY with two arguments.
1475 eval.c Added type checking to the above cases.
1476 value.h Added not_lval_constant to the lval_type ennumerated type.
1477 not_lval_constant means that the value is a constant
1478 value; that is 3 or 'a' or TRUE, not as in a constant
1479 identifier. This is used to help coerce numbers such as 3
1480 to either signed or unsigned numbers.
1481 valops.c Added the function value_coerce_constants() which coerces
1482 constant integers as following: if one is a constant and
1483 the other is not, the constant's type is set to the type
1484 of the other argument. If both are constants and one is
1485 signed, the other is converted to a signed constant.
1487 Sat Jun 29 17:26:29 EDT 1991
1489 valarith.c Added a better range checker. It now checks range
1490 (successfully) on integral operations [+-] (signed and
1491 unsigned) for any C sized type. Still does not work well
1492 for multiplication.)
1493 int_in_size() returns an integer that is coerced to fit into
1494 specified number of bytes.
1496 Mon Jul 1 13:04:14 EDT 1991
1498 language.[ch] Added the function binop_result_type(), which returns the
1499 builtin (struct type *) type that would be the result of a
1500 binop on the two values V1 and V2.
1502 Wed Jul 3 19:22:53 EDT 1991
1504 source.c Extended source_info() to include the source language in
1505 the output from "info source".
1507 Fri Jul 5 13:48:52 EDT 1991
1509 utils.c Moved the support functions for the GDB set/show commands
1510 dealing with language into language.c.
1511 language.c Added the function language_info(), which displays info
1512 about the current working language, type and range check
1513 settings. Called via the GDB command "info language".
1514 Added an initialization routine _initialize_language(),
1515 that sets defaults for the language, type and range
1516 variables and sets up the new GDB commands.
1517 main.c Language setup moved to language.c.
1520 Mon Jul 8 10:10:22 EDT 1991
1522 valarith.c Debugged the range checker for arithmetic. Still does not
1523 work for multiplication very well.
1525 Mon Jul 8 12:40:37 EDT 1991
1527 language.[ch] Added the function value_true() which returns non-zero if
1528 its argument represents a boolean true value.
1529 breakpoint.c Changed breakpoint_cond_eval() to call value_true() to
1530 check the truth of an expression.
1532 Thu Jul 11 12:51:34 EDT 1991
1534 language.[ch] Added the predicate structured_type(), which returns
1535 non-zero if the argument is a structured type.
1536 Added the predicate pointer_type(), which returns non-zero
1537 if the argument is a pointer type.
1538 eval.c Added the ability to do addition and substraction on
1539 pointers and integers. This case simply bypasses the
1542 Thu Jul 11 14:41:42 EDT 1991
1545 Added the symbol N_DEFD (0x4a) which is a definition
1546 module dependency that is used by the GNU Modula-2
1547 compiler and the linker. It is not important to GDB,
1548 except that [dbx|coff|mips]read.c should ignore these
1551 Fri Jul 12 16:07:00 EDT 1991
1553 valprint.c Changed the TYPE_LENGTH(type) >= 0 to TYPE_LENGTH(type) >
1554 0 in val_print(). Also added statements to the else part
1555 to coerce type (argument to val_print) to a pointer type
1556 if it is an "array of unspecified length".
1557 valops.c Added the function value_m2_string(), which returns a
1558 (value) value which is a constant string, whose type is
1559 (ARRAY [0..n] OF CHAR). The length field of the type
1560 structure is set to zero, so it will be interpreted as an
1561 "array of unspecified length".
1562 stack.c Moved the language/frame mismatch check to
1563 main.c:execute_command().
1564 main.c The working language is recorded each time
1565 execute_command() is executed. If working lang has
1566 changed during its execution, then the new
1567 language/type/range info is printed out for the user. If
1568 the working language does not match the language of the
1569 frame, a warning is issued.
1571 Sat Jul 13 16:16:39 EDT 1991
1573 eval.c Moved all the type-checking stuff for operators to
1574 language.[ch] language.c. This is so we can keep language-specific
1575 stuff (like for what type operators are defined) in
1577 language.[ch] Added the function binop_type_check(), which checks to see
1578 if its two (value) arguments are type-compatible with its
1579 opcode argument. The opcode should represent an operation
1580 involving an operator. Also added the macro function
1581 unop_type_check, which calls binop_type_check with a
1582 NULL second argument.
1583 expprint.c Added Modula-2 operators to the op_print_tab, so info
1584 expression.h break works correctly. Also added "op_string", which
1585 returns the string corresponding to the (enum exp_opcode)
1586 opcode that is its argument.
1589 Sat Jul 13 18:26:18 EDT 1991
1591 coffread.c Added code to record the type of function arguments with
1592 each paricular function. Code is very similar to that
1594 dbxread.c Moved add_param_to_type() to symtab.c
1595 symtab.[ch] Added function add_param_to_type() from dbxread.c
1597 *** NOTE: The above additions have not been tested.
1599 Mon Jul 15 12:50:47 EDT 1991
1601 langauge.[ch] Added the functions type_error and range_error, which work
1602 like error() except if the type/range mode is set to
1603 *_mode_warn, then they do not do a return_to_top_level(),
1604 but merely print a warning.
1605 Also changed [set|show]_[type|range]_command() to support
1606 the new "warn" feature.
1608 Thu Jul 18 17:50:54 EDT 1991
1610 mipsread.c Added code to record the type of function arguments with
1611 each particular function. Code is very similar to that
1614 *** NOTE: The above additions have not been tested.
1616 Fri Jul 19 11:19:10 EDT 1991
1618 defs.h Added macros MAX_OF_SIZE, MIN_OF_SIZE, UMAX_OF_SIZE, and
1619 UMIN_OF_SIZE, which when given a size of a numeric type,
1620 return the maximum and minimum value it can hold. UMAX...
1621 and UMIN... return the result for unsigned types.
1622 symtab.h Added the macros MAX_OF_TYPE and MIN_OF_TYPE to operate on
1623 struct types. They call above macros.
1624 dbxread.c Renamed the MAX and MIN_OF_TYPE macros to ..._OF_CTYPE to
1625 avoid a name conlict with the above.
1626 c-exp.y Added range checking on numeric constants in
1627 parse_number() for completeness.
1628 valarith.c Made binop_user_defined_p() and unop_user_defined_p()
1629 return 0 if working_lang is not language_c.
1631 Thu Aug 8 14:17:22 EDT 1991
1635 breakpoint.c Documentation strings of some commands changed to
1636 eliminate the references to the C language where
1639 Tue Aug 13 15:48:03 EDT 1991
1641 m2-exp.y Added qualified identifiers to the grammar. The semantics
1642 are slightly different from those of the GDB operator ::
1644 m2-exp.y Added a rule to each grammar of the form: start ::= exp |
1645 type_exp, where type_exp is any valid type expression.
1647 eval.c Added the opcode OP_TYPE, and an error case in eval.c.
1648 printcmd.c Modified ptype_command() so it actually parses the input
1649 (necessary for type expressions with scope qualifiers).
1650 Added the function ptype_eval() which expects an
1651 expression composed of one OP_TYPE element.
1652 *.[ch] Replaced all occurences of parse_c_expression with
1654 *.[ch] Replaced all occurences of parse_c_1 with parse_exp_1
1656 [End of ChangeLog entries from Andrew Beers for Modula-2 support.]
1658 Mon Sep 16 17:19:46 1991 John Gilmore (gnu at cygnus.com)
1660 Small fixes from Peter Schauer:
1662 * infrun.c (child_attach): Lint.
1663 * solib.c (find_solib): Handle shared libs version 2.
1665 Small fixes from David Wood:
1667 * xm-ultra3.h (SYS_SIGLIST_MISSING): Typo.
1671 * remote-vx.c: Move <stdio.h> to top, for FILE. Fix from
1672 John S <basrai%kanga.dnet@c3po.sm-alc.af.mil>.
1674 * utils.c (wrap_here): Avoid wrap action of fputs_filtered if
1675 chars_per_line is at maximum (user typed `set width 0'). Fix
1676 from Andreas Schwab <schwab@ls5.informatik.uni-dortmund.de>.
1678 Tue Sep 17 17:31:04 1991 Stu Grossman (grossman at cygnus.com)
1680 * coredep.c: include ptrace.h where necessary.
1681 * mipsread.c(parse_lines): fix unsigned char problem that was
1682 messing up line numbers on SGI's and possibly other MIPS based
1684 * infrun.c (child_create_inferior): use better test to check
1685 return val from setpgrp().
1686 * tm-irix3.h, xm-irix3.h, tconfig/irix3, xconfig/irix3: add these
1687 for sgi/irix support.
1689 Wed Sep 18 04:33:31 1991 Per Bothner (bothner at cygnus.com)
1691 * mipsread.c (parse_symbol): Put non-static procedures
1692 in the global block.
1694 Fri Sep 13 00:14:52 1991 John Gilmore (gnu at cygnus.com)
1696 Patch together `text_start' and `text_end' for 29K port.
1698 * exec.c (exec_command): If NEED_TEXT_START_END, define the
1699 variables and set them based on the exec file.
1700 * am29k-tdep.c: declare text_start.
1701 * valops.c (call_function_by_hand): declare text_end.
1703 * inferior.h: Eliminate CANNOT_EXECUTE_STACK in favor of
1704 defining CALL_DUMMY_LOCATION as BEFORE_TEXT_END. This is
1705 because machines that do this will also have to know to
1706 set NEED_TEXT_START_END. Besides, it was a redundant way to
1708 * tm-29k.h, tm-convex.h, tm-np1.h: Eliminate
1709 CANNOT_EXECUTE_STACK, define CALL_DUMMY_LOCATION and
1710 NEED_TEXT_START_END.
1712 Thu Sep 12 00:22:24 1991 John Gilmore (gnu at cygint.cygnus.com)
1714 AMD 29000 changes from David Wood <wood@david.ultra.nyu.edu>:
1716 * Makefile.in (CLIBS): Put XM_CLIBS and TM_CLIBS at end.
1717 Pass MUNCH_DEFINE to munch whenever we run it.
1718 * am29k-pinsn.c (print_insn): Handle NOP specially. Avoid %#x
1719 format string; use 0x%x instead.
1720 * am29k-tdep.c: Use DUMMY_SAVE_GREGS and RETURN_REGNUM.
1721 * ultra-xdep.c, xm-ultra.h: New files for Ultracomputer host system.
1722 * xm-rtbsd.h: New host support for RT/PC running BSD Unix.
1723 * inflow.c: Handle `short' process group IDs.
1724 * infptrace.c (fetch_register): Support CANNOT_FETCH_REGISTER,
1725 and check for ptrace errors.
1726 * coffread.c (SDB_REG_TO_REGNUM): Define if not already.
1727 (coff_symfile_init): Initialize text_bfd_scnum.
1728 (read_coff_symtab): Use it to find the text [and absolute?] sections.
1729 * ../config.sub: Add vendor nyu and os "sym[1-9]*".
1730 * configure.in: Add hosts rtpc-*-* and a29k-*-*.
1731 Merge target arm case with other "easy" cases. Add target
1732 cases a29k-*-none (rehack of am29k), a29k-*-kern (remote to
1733 Ultracomputer kernel), and a29k-*-sym1 (ultracomputer OS's user
1735 * minimon.h, remote-adapt.c, remote-mm.c: Add.
1736 * munch: Cope with RT/PC putting fns in data segment.
1737 Restore ability to override `nm' by specifying MUNCH_NM.
1738 * xconfig/rtbsd, xconfig/ultra3: New host systems.
1739 * tconfig/a29k: Rename from tconfig/am29k. Add remote-mm
1740 and remote-adapt. Remove encapsulated coff #define's (the
1741 support should go in BFD, and gdb shouldn't know or care).
1742 * tconfig/a29k-kern: Same, but for remote kernel debugging.
1743 * tconfig/ultra3: For debugging user processes on Ultra3/Sym1.
1744 * tm-29k.h: Update BADMAG (though it should go away).
1745 Allow the register definitions to be overridden in another
1746 tm-file. Fix SR_REGNUM. Add a mess of _REGNUM's. Separate
1747 RETURN_REGNUM from GR96_REGNUM and DUMMY_SAVE_GREGS from
1748 DUMMY_SAVE_GR96, for handling kernel calling conventions
1749 that use GR64+ rather than GR96+.
1750 * tm-ultra3.h: New file, for use on Ultra3 Unix as well as for
1751 remote debugging of Ultra3 kernel. Includes tm-29k.h and
1752 overrides various things.
1754 * remote-mm.c (mm_attach, mm_wait): Handle attach like
1755 child_attach does, making a clean stop in the newly attached
1757 * remote-eb.c: Lint.
1759 * coffread.c: Make coffread independent of any particular
1760 variant of COFF. Avoid #include-ing any particular one except
1761 internalcoff.h. BFD now passes key values for symbol reading
1762 as part of its coff_data structure (LINESZ, SYMESZ, AUXESZ,
1763 and the symbol masks and shifts); use them.
1764 Remove obsolete end_of_text_addr.
1766 * exec.c: Remove unused include files.
1768 Wed Sep 11 19:38:44 1991 John Gilmore (gnu at cygint.cygnus.com)
1770 * Makefile.in (documentation targets): Pass $(M4).
1771 Bugfix from eggert@twinsun.com (Paul Eggert).
1773 * stack.c (down_silently_command): Check for stack existence.
1775 Tue Sep 10 23:08:29 1991 John Gilmore (gnu at cygint.cygnus.com)
1777 * Makefile.in (VERSION): Update to 4.0.3.
1779 Tue Sep 10 09:19:29 1991 John Gilmore (gnu at cygint.cygnus.com)
1781 * core.c (core_file_command): Print frame at coredump with
1782 its level number, by calling print_stack_frame.
1783 * frame.h: Add selected_frame_level, print_stack_frame.
1784 * frame.h, stack.c: Remove print_sel_frame, print_selected_frame.
1785 * convex-tdep.c, convex-xdep.c, infcmd.c, inflow.c, infrun.c:
1786 Change print_sel_frame and print_selected_frame callers to
1789 * dbxread.c (read_ofile_symtab): Avoid empty else clause.
1790 * symfile.c (free_named_symtabs): Ditto.
1791 * main.c (main): wrap_here needs an arg.
1792 * solib.c (find_solib): Avoid memory access if _DYNAMIC is zero.
1793 (solib_add): Avoid noise.
1794 (solib_create_inferior_hook): Lint.
1795 (sharedlibrary_command): Move dont_repeat to here.
1796 * utils.c (error): Call wrap_here to force buffered output.
1798 Small patches from Peter Schauer:
1800 * coffread.c (start_symtab): Free any existing line_vector before
1802 (read_coff_symtab): Ditto for type_vector.
1804 * source.c (lines_to_list): New variable, replacing function.
1805 (all uses): Use as variable.
1806 (_initialize_source): Add 'set listsize' and 'show listsize'.
1807 * utils.c (lines_to_list): Remove function.
1808 * stack.c (print_frame_info): Use as variable.
1809 * defs.h (lines_to_list): Remove declaration.
1811 Mon Sep 9 13:45:57 1991 John Gilmore (gnu at cygint.cygnus.com)
1813 * breakpoint.c (insert_breakpoints): Restore warning about
1814 the program might be running in another process, but only for
1815 systems with this brain death (#ifdef ONE_PROCESS_WRITETEXT).
1816 * xm-hp300bsd.h, xm-mips.h, xm-vax.h: Define it.
1818 * utils.c (error): if error_pre_print is set, print the string
1820 * main.c (main, print_gnu_advertisement, print_gdb_version):
1821 Reformat legalese so it always prints, but acts as an "I'm here"
1822 message while symbols are being read. If any errors occur,
1823 print a few newlines to set off the message and start it at the
1824 left margin. Remove mention of "help" command, and don't yak
1825 about symbol reading.
1826 (catch_errors): Error string is now printed first in case of
1828 * command.c (undef_cmd_error, lookup_cmd): On undefined command,
1829 suggest the "help" command.
1831 * Makefile.in (VERSION): Set to 4.0.2.
1833 Thu Sep 5 23:49:48 1991 John Gilmore (gnu at cygint.cygnus.com)
1835 * .gdbinit: Remove useless "rr" command. Set complaints
1836 to 1 for people debugging gdb.
1838 * breakpoint.c, remote-vx.c: Reword strings printed by
1839 catch_errors callers.
1841 Wed Sep 4 11:07:50 1991 John Gilmore (gnu at cygint.cygnus.com)
1843 * WHATS.NEW: "history write -> history save". Doc "write on/off".
1844 (Fix from kenc@viewlogic.com.)
1846 Fix some infrastructure to be able to cope with host and target
1847 machines with different sized basic types (ints, ptrs, etc).
1848 (Idea from pierre@la.tce.com (Pierre Willard).)
1850 * values.c (value_from_longest): Rename from value_from_long.
1851 Handle pointer types as well as integers, so that targets with
1852 different pointer sizes from the host can be accomodated.
1853 * breakpoint.c, convex-tdep.c, eval.c, expprint.c, printcmd.c,
1854 valarith.c, valops.c, valprint.c, value.h, values.c: Rename
1855 uses of value_from_long to value_from_longest.
1856 * eval.c, findvar.c, printcmd.c, valarith.c, valops.c: Pass
1857 the correct pointer type to value_from_long{est}.
1859 * doc/gdb.texinfo ($_, $__): Describe types of these variables.
1861 * remote-vx.c: Remove obsolete code for calling functions via
1862 vxworks kludge interface (it referenced value_from_long).
1864 * valops.c (value_string): Find malloc with lookup_misc_func, not
1867 Tue Sep 3 18:37:46 1991 John Gilmore (gnu at cygint.cygnus.com)
1869 Make writing to files work properly. (Fixes to BFD are also needed.)
1871 * core.c (core_open): Open file ourselves, read or r/w, depending on
1872 write_files. Use bfd_fdopenr.
1873 * gdbcore.h (write_files): New variable.
1874 * exec.c (write_files): Define variable, add set&show for it.
1875 (exec_file_command): Use write_files to open for read or r/write.
1877 Make shared library reading happen automatically. These changes
1878 are mostly from Peter Schauer <pes@regent.e-technik.tu-muenchen.de>.
1880 * inferior.h (stop_soon_quietly): Add to exported variables.
1881 * infrun.c (child_create_inferior): call solib hook, if defined.
1882 (child_attach): call solib hook, if defined.
1883 * solib.c: Include inferior.h. Add from_tty to so_list as kludge.
1884 (find_solib): Use lookup_misc_func rather than hand-rolled.
1885 (symbol_add_stub): New stub for catch_errors.
1886 (solib_add): Avoid output if !from_tty. Catch errors rather
1887 than just calling symbol_file_add and bombing.
1888 (solib_create_inferior_hook): Interface with the target process
1889 to let it read and alloc shared libs, then figure out what it did.
1891 * core.c (validate_files): Fix typo, soften warning.
1892 (Fix from Hiroto Kagotani <kagotani@cs.titech.ac.jp>.)
1894 * utils.c (fputs_demangled): Avoid duplicate printing if
1895 demangling is off. (Fix from J.T. Conklin <jtc@cayenne.com>.)
1897 * infrun.c (proceed): Cast -1 to (CORE_ADDR) before comparing.
1898 (Fix from pierre@la.tce.com (Pierre Willard).)
1900 * main.c (catch_errors): Change argument to a char * from an int,
1901 since a char * can point to a struct full of glop, but an int
1902 is not guaranteed to be able to hold a pointer.
1903 * breakpoint.c (breakpoint_cond_eval, bpstat_stop_status,
1904 breakpoint_re_set_one, breakpoint_re_set): Adapt.
1905 * core.c (core_open, solib_add_stub): Adapt.
1906 * remote-vx.c (symbol_stub, add_symbol_stub, callers): Adapt.
1908 Wed Aug 28 18:18:05 1991 John Gilmore (gnu at cygint.cygnus.com)
1910 * Makefile.in: Update VERSION to 4.0.1. Evade GNU Make bug
1911 by adding .NOEXPORT target.
1913 Fri Aug 23 17:14:25 1991 John Gilmore (gnu at cygint.cygnus.com)
1917 * Makefile.in (VERSION): Roll to 4.0.
1918 (gdb.tar.Z): Make refcard.ps as well, for shipment.
1920 Fri Aug 23 14:07:09 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1922 * doc/gdb.texinfo: minor rewordings, crossref to ptype from print,
1925 * doc/Makefile, Makefile.in: generate "gdb-all.texi" rather than
1928 * doc/rdl-apps.texi: renamed from rdl-apps.texinfo
1930 * Makefile.in, doc/Makefile, doc/.Sanitize, doc/gdb.texinfo:
1931 reflect above name change
1933 * WHATS.NEW: correct pointer to refcard.
1935 * doc/gdb.texinfo: update New Features, Installing
1937 * doc/gdbint.texinfo: add short description of configure +template
1939 Fri Aug 23 11:46:08 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1941 * doc/gdb.texinfo: update, fix bugs in "Installing" appendix
1943 Fri Aug 23 01:02:00 1991 John Gilmore (gnu at cygint.cygnus.com)
1945 * Makefile.in: Add config.sub, make doc/rdl-apps.texinfo for
1946 tar file, add dependencies for referenced doc files.
1948 Thu Aug 22 22:17:06 1991 Stu Grossman (grossman at cygint.cygnus.com)
1950 * coffread.c, symfile.c, stack.c: saberized.
1952 Thu Aug 22 16:20:27 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1954 * doc/refcard.tex: permuted Essential Commands sec
1956 * doc/gdb.texinfo: new C++ chapter; revised installation appendix;
1958 set/show symbol-reloading
1959 default set complaints 0
1961 RET-repeat disabled after prompted long displays
1962 processID (attach) interpretation of 2nd GDB cmdline arg
1964 Thu Aug 22 14:05:47 1991 Stu Grossman (grossman at cygint.cygnus.com)
1966 * expread.y, coffread.c, dbxread.c, target.c, mem-break.c,
1967 cplus-dem.c, values.c, valprint.c, symfile.c, remote.c,
1968 breakpoint.c, main.c: lint.
1970 Thu Aug 22 02:02:26 1991 John Gilmore (gnu at cygint.cygnus.com)
1972 Install new configuration scheme for GDB and friends.
1974 * config.sub: Translate ordinary names to three-part names.
1975 * configure: Use three-part names internally.
1976 * configure.in: Translate three-part names to filenames.
1978 * README, WHATS.NEW: Update for gdb-4.0.
1979 * Makefile.in: Roll VERSION to 3.99.
1981 Wed Aug 21 18:21:09 1991 John Gilmore (gnu at cygint.cygnus.com)
1983 * infptrace.c (KERNEL_U_ADDR_BSD): Include a.out.gnu.h.
1984 * i960-tdep.c, m68k-tdep.c, sparc-tdep.c, tm-i960.h,
1985 tm-m68k.h, remote-nindy.c: Change ext_format_XXX structs
1986 to single structures rather than arrays; when passing
1987 their address, use &. This avoids trouble with bdead compilers.
1988 * mcheck.c: Don't include <stdlib.h>; just declare "void abort();"
1989 instead. This avoids portability headaches.
1990 * mips-tdep.c (mips_do_registers_info): Only print FP regs if
1992 * source.c (open_source_file): Avoid ANSI const bdeath by
1993 skipping declaration and then casting result value.
1994 * tm-hp300bsd.h: Clarify comment.
1995 * utils.c (strstr): Result is const char *; ANSI bdeath.
1996 * xm-hp300bsd.h: Define HOST_BYTE_ORDER. Redefine INT_MIN,
1997 since system include file defines it differently from "defs.h",
1998 though the two are equivalent for our purposes.
1999 * tconfig/hp300bsd: Add m68k-tdep.o.
2001 Tue Aug 20 16:01:11 1991 John Gilmore (gnu at cygint.cygnus.com)
2003 * tconfig/sun*4: Remove warnings about system assembler.
2005 Mon Aug 19 13:44:46 1991 John Gilmore (gnu at cygint.cygnus.com)
2007 * mcheck.c: Avoid warning about undeclared abort fn.
2008 * tm-sparc.h (PC_ADJUST): Avoid calling error() from this;
2009 it causes recursive calls to error() when used in cleanups.
2010 To do so requires that we make it a function, so we do.
2011 * sparc-tdep.c (sparc_pc_adjust): New implem of PC_ADJUST.
2012 * utils.c (do_cleanups): Remove the current cleanup from the
2013 chain *before* calling it, in case error() is called from it.
2014 The result won't be pretty, but won't be an infinite loop either.
2016 Mon Aug 19 00:41:04 1991 Michael Tiemann (tiemann at cygint.cygnus.com)
2018 * dbxread.c (read_struct_type): Grok anon structs for C++.
2019 (vb_name, vptr_name): Null terminate these strings.
2021 Fri Aug 16 08:31:03 1991 John Gilmore (gnu at cygint.cygnus.com)
2023 Minor bug fixes from BSD Net2 gdb:
2025 * blockframe.c (get_prev_frame_info): If FRAME_CHAIN_COMBINE
2026 returns 0, there is no previous frame.
2027 * breakpoint.c (commands_command): If !from_tty, don't call
2028 input_from_terminal_p().
2029 * dbxread.c (record_misc_function): Speed up slightly.
2030 (compare_psymbols): Ditto.
2031 * infcmd.c (do_registers_info): Take a second argument to
2032 determine whether to print float registers. "info registers"
2033 does not do so anymore. "info all-registers" does, now.
2034 * mips-tdep.c, pyr-tdep.c (xxx_do_registers_info): Take second
2036 * tm-mips.h, tm-pyr.h (DO_REGISTERS_INFO): Pass second arg.
2037 * inflow.c (initialize_inflow): Set tflags_ours correctly.
2041 * breakpoint.c (bpstat_do_actions): Use a cleanup to restore
2042 executing_breakpoint_commands if we are interrupted by error.
2043 * coffread.c (init_lineno): Avoid problem with zero-sized linetab
2044 versus malloc/free. From: john@labtam.labtam.oz.au (John Carey).
2045 * core.c (solib_add_stub, core_open): Call SOLIB_ADD inside a
2046 catch_errors() so we can setup the frame regardless of whether
2047 the shared libs work.
2048 * ieee-float.c (double_to_ieee_extended): Get exponent from
2049 right place in little-endian systems. From John Carey.
2051 Thu Aug 15 18:43:57 1991 John Gilmore (gnu at cygint.cygnus.com)
2053 * main.c: Remove unused terminating_signals and catch_termination().
2054 (long_options): Terminate with a zero element.
2055 [Bugfix from Atsuo Kawaguchi <atsuo@hark86.harl.hitachi.co.jp>.]
2056 (gdb_readline): Make call-compatible with readline.
2057 (init_signals): Improve comments re vfork vs. signal.
2059 * utils.c (prompt_for_continue): Use new gdb_readline().
2060 If we prompt for continuation, we don't let CR repeat the previous
2061 command, once we get back to a prompt. It's too easy to keep
2062 hitting CR, expecting "--more--" prompts, and have some long
2063 command start repeating on you.
2065 Tue Aug 13 16:17:56 1991 John Gilmore (gnu at cygint.cygnus.com)
2067 * blockframe.c (frameless_look_for_prologue): Speed up by
2068 calling SKIP_PROLOGUE_FRAMELESS_P if it's defined.
2069 * tm-sparc.h (SKIP_PROLOGUE, SKIP_PROLOGUE_FRAMELESS_P):
2070 Define two variants, one faster.
2071 * sparc-tdep.c (sparc_frame_chain): Use target_read_memory
2072 and return zero, rather than giving an error.
2073 (setup_arbitrary_frame): Initialize the PC in the new frame.
2074 (skip_prologue): Add a second arg saying whether we're just
2075 checking for a frameless function or not.
2077 * core.c (core_open, core_close, core_xfer_memory): Move
2078 section table pointers and bfd* into the target_ops.
2079 (core_open): Allow errors in shared lib reading, etc.
2080 (core_files_info): Describe shared library sections.
2082 * exec.c (exec_open, exec_close, exec_xfer_memory, xfer_memory,
2083 exec_files_info, set_section_command): Move section table
2084 pointers and bfd* into the target_ops.
2085 (add_to_section_table): Add BFD to section table.
2087 * target.c (target_xfer_memory, target_info): Pass target to
2088 xfer_memory and target_info functions.
2091 * gdbcore.h: Move struct section_table.
2092 * target.h: New home of struct section_table.
2094 * solib.c (solib_add): New argument is the target_ops whose
2095 section list is to be added to, if any. Reallocate the
2096 sections in that target to add any that come from shared libs.
2097 (throughout) so_sections renamed to sections.
2098 (solib_xfer_memory): Deleted.
2099 * tm-sunos.h (SOLIB_ADD): Add target argument.
2100 (SOLIB_XFER_MEMORY): Delete.
2102 * core.c, exec.c, inftarg.c, remote-eb.c, remote-nindy.c,
2103 remote-vx.c, remote.c, target.c, target.h: Remove add_syms vector
2104 from target_ops. It's the same on all targets. Add two section
2105 pointers to target_ops.
2107 * stack.c (find_relative_frame): Dump ancient algorithm for
2108 "down", just use handy "next" pointers.
2109 (frame_command): Don't error if there is no stack; let user
2112 * inflow.c (new_tty_prefork, new_tty): New prefork routine
2113 modifies static state in the parent process; new_tty itself
2114 runs in the child and modifies the child's file descriptors
2115 to match the saved static state.
2116 * infrun.c (child_create_inferior): Call new_tty_prefork,
2119 * infptrace.c (child_xfer_memory): Add ignored target arg.
2120 * remote-eb.c (eb_xfer_inferior_memory): ''
2121 * remote-nindy.c (nindy_xfer_inferior_memory): ''
2122 * remote-vx.c (vx_xfer_memory): ''
2123 * remote.c (remote_xfer_memory): ''. Rename from
2124 remote_xfer_inferior_memory.
2126 * main.c (main): Only try to attach "corefile" argument if
2127 it starts with a digit.
2129 * symfile.c (symbol_reloading): New "set/show" variable.
2130 (symbol_file_add): Shorten message about symbol reading.
2131 (add_symbol_file_command): Merge with add_syms_addr_command,
2132 since this should work on all targets now.
2133 (stop_whining): Default to zero, to shut up complaints
2134 about bad symbol tables on many systems.
2135 (free_named_symtabs): Just exit unless symbol_reloading.
2137 * xm-sun3os4.h, xm-sun4os4.h: Define BROKEN_LARGE_ALLOCA,
2138 and add comment explaining shared library screw.
2140 * source.c: #if defined => #ifdef.
2142 Thu Aug 8 12:23:19 1991 John Gilmore (gnu at cygint.cygnus.com)
2144 * doc/gdbint.texinfo: Improve doc on porting to new OS's.
2146 Tue Aug 6 17:16:15 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
2148 * doc/rdl-apps.texinfo: provide default readline-appendix finder
2149 (doc/Makefile knows how to make one for local config)
2151 * Makefile.in: use doc/Makefile for doc targets
2153 * doc/Makefile: GDB documentation now has its own Makefile
2154 doc/refcard.tex: renamed from "gdbrc.tex"
2155 doc/.Sanitize: add Makefile; recognize renamed refcard.tex
2156 doc/gdbint.texinfo: add markup in "Cleanups" chapter
2159 Fri Aug 2 00:13:06 1991 John Gilmore (gnu at cygint.cygnus.com)
2161 * values.c (baseclass_addr): When reading target memory, use the
2162 length of the basetype, not the upper type. We've only malloc'd
2163 enough space for the basetype, leading to errors in free().
2165 * expprint.c (print_subexp): Print UNOP_MEMVAL of an OP_LONG that
2166 ends up as a function specially, since we know the actual type of
2167 the pointed-to address. This (somewhat) fixes display of
2168 expressions that include misc_function_vector names. Try `cond 1
2169 !strcmp("a","b")' then `i b'.
2171 * infrun.c: Move DO_DEFERRED_STORES from proceed() to resume().
2172 The child can be proceeded from inside wait_for_inferior in
2173 evaluating breakpoint conditions, and DO_DEFERRED_STORES was
2174 getting skipped in that case.
2176 * expprint.c (print_subexp): Use filtered output, since the
2177 subroutines we call use it, otherwise the output is horribly
2178 mangled, since output of wrappable stuff comes out late.
2180 * Makefile.in: Bump VERSION to 3.98.1
2182 * infrun.c (child_create_process): Use execlp to find the
2183 shell to exec our target program. This requires some fiddling
2184 with `environ' since there is no execlpe().
2186 Thu Aug 1 15:35:17 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
2188 * Makefile.in, doc/gdbrc.tex, doc/rc-* (new files):
2189 Minor rearrangement of refcard permits two new make targets--
2190 gdbrc.dvi DVI output for refcard, using CM fonts
2191 gdbrc.ps PostScript refcard, using PS fonts
2193 Wed Jul 31 16:46:21 1991 John Gilmore (gnu at cygint.cygnus.com)
2197 * TODO, Projects, WHATS.NEW, README: Update for gdb-3.98.
2198 * Makefile.in (gdb-all.texinfo): Avoid touching file if M4 dies.
2200 Wed Jul 31 16:35:58 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
2202 * doc/gdb.texinfo: last changes for release.
2203 Minor typo and formatting fixes; incorporated most fixes remaining from
2204 filed mail commenting on earlier drafts.
2206 Added warnings: pipes don't work in run command;
2207 conditions are converse of assertions;
2208 step over fn without debug info goes to next fn;
2209 vars may have "wrong" values near fn entrance, exit
2211 Added example from Kingston on printing repeated nonadjacent values
2213 Added explicit mention that in Emacs gdb mode C-c and C-z are like
2214 shell mode for signals
2216 Renamed "Stepping and Continuing" to "Continuing and Stepping" so it
2217 doesn't sound so much like its parent "Stopping and Continuing"; also
2218 moved entries on continue to top of section, so they don't get lost.
2220 Improved installation directions in appendix, added manual formatting
2223 Tue Jul 30 17:26:39 1991 John Gilmore (gnu at cygint.cygnus.com)
2225 * configure.in: Remove xm.h and tm.h even if we aren't linking
2226 new ones, so "./configure sun4; ./configure none" does the right
2227 thing. Assume that alldeps.mak and depend are already built in
2228 srcdir, and avoid running "make" (particularly "make depend",
2229 which involves "gcc") from inside configure. Build Makefile
2230 directly rather than building Makefile.conf first.
2231 * configure: Regenerate with above changes.
2232 * Makefile.in: Use $(BISON) to find bison. Roll VERSION
2233 to 3.98. Revise gdb.tar.Z procedure to produce a file
2234 called gdb-$(VERSION).tar.Z but which unpacks into a
2235 directory called "gdb". Move non-source files out of
2236 $(SFILES_SUBDIR). Pretty up alldeps.mak with comments.
2237 (depend): Don't try to do "gcc expread.y".
2238 (expread.o): Update dependencies by hand.
2240 Mon Jul 29 15:21:09 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
2243 Fixed a variety of small typos that prevented info from formatting
2244 cleanly; altered too-long heading for GPL Appendix, as discussed
2245 w/RMS; Changed date on cover to July 91.
2247 Fri Jul 26 13:20:02 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
2250 (1) Applied some fixes due to comments from Larry Breed (easier ones
2251 through chapsec 5.2)
2252 (2) Eliminated use of @footnote---had my doubts about it anyways, and
2253 it's broken in latest texinfo
2254 (3) Introduced *some* use of [] for optional arguments, where
2255 explanation is not simpler by listing cmd w arg and cmd w/out arg
2256 separately. Still not using @deffn.
2257 (4) Dropped in GPL-2. NOTE: one of GPL-2 or texinfo is broken; a
2258 couple of headings are too long. Need patches to texinfo or revision
2261 * Partial update to README (which still needs work for this
2262 release!): (1) use of configure corrected for new script,
2263 (2) "make gdb.dvi" and "make gdb.info" mentioned.
2265 Wed Jul 24 06:44:02 1991 John Gilmore (gnu at cygint.cygnus.com)
2267 * symtab.c (lookup_symbol): Don't complain right off about
2268 no debug symbols; use the misc function vector first.
2269 (list_symbols): Use misc function vector to find symbols
2270 that don't have debug info, and print them.
2271 (find_pc_symtab): Temporarily avoid fatal() when psymtab
2272 PC range doesn't match symtab PC range, as it does on the
2273 MIPS because our symtab reading isn't perfect.
2275 * dbxread.c (dbx_symfile_read): Make warning about
2276 "no debug symbols" slightly nicer.
2278 * source.c (select_source_symtab): If "main" symbol exists,
2279 but decode_line_spec can't find line info, don't just return
2280 a zero; try other source symtabs or give an error.
2282 * mipsread.c (parse_partial_symbols): Sort the psymtabs by
2283 their low addresses first, then rip through fixing high addrs.
2285 * ns32k-opcode.h (sfsr): Bugfix from Rune Nerg}rd,
2286 <runene@ifi.uio.no>.
2287 (NS32K_SVC_IMMED_OPERANDS): Reverse the #ifndef.
2289 Tue Jul 23 18:52:43 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
2291 * Minor, mostly mechanical, cleanup of doc subdir for clean
2292 makeinfo'ing and TeXing; also ensured gdb-all.texinfo (post-m4)
2293 and gdb.info (post- texinfo2 makeinfo) generated for distribution.
2295 Sun Jul 21 03:54:52 1991 John Gilmore (gnu at cygint.cygnus.com)
2297 Mostly MIPS and general symbol-reading fixups.
2299 * doc/gdbint.texinfo: Add documentation on symbol-reading
2302 * mipsread.c: Remove kludges around #include "ecoff.h".
2303 Remove redefinitions of a_magic, etc, no longer used.
2304 (parse_symbol, ): Convert "Internal:" printfs to complain()ts.
2305 Fix global overview comments to match symfile.c protocol.
2306 (mipscoff_new_init): Eliminate cur_hdr if we have one.
2307 (mipscoff_symfile_read): Eliminate unused code. Avoid
2308 sorting all the symtabs, when all we have read here is psymtabs.
2309 The symtabs are sorted as they are created anyway. Tell
2310 condense_misc_bunches whether we're mainline.
2311 (psymtab_to_symtab_1): Pass filename when recursing, to make
2312 stack trace more informative.
2313 (parse_partial_symbols): Assume cur_hdr as argument.
2314 (read_mips_symtab): Don't clobber cur_hdr, so it can be freed.
2315 Pass cur_hdr implicitly to parse_partial_symbols. Avoid checking
2316 the TYPE_NAME of char *, since that's done in symfile.c.
2317 (free_numargs, parse_symbol, add_symbol, add_block,
2318 shrink_linetable): Declare these fns void.
2319 (upgrade_type): Convert tree of if's to switch. Clean up
2320 bogus "off == 0" handling with a complaint. Avoid setting
2321 field bitpos and bitsize of array with lower and upper bounds.
2322 Check specified bitsize of elements against their actual type's
2323 bitsize, and complain if different. Complain about unknown
2325 (parse_fdr): Don't assume sizeof(char *) == sizeof (struct *).
2326 (psymtab_to_symtab_1): Print names of subsidiary files that
2327 are being read in. FIXME, we read far too many files. This code
2328 is not the problem, the problem is in parse_fdr where the psymtabs
2330 (cross_ref): Result should indicate that we used one aux entry
2331 normally, or two if we encountered a "next" entry. This used
2332 to leave the caller pointing at the wrong aux entry.
2333 (add_symbol): If overflowed cur_block, reallocate it larger,
2334 chase all pointers to it, and complain(), rather than clobber memory.
2335 (shrink_block): Use xrealloc rather than xmalloc-and-copy.
2336 (new_field): Only allocate one field initially, not two.
2337 Pull ++ out of macro argument. Simplify.
2338 (_initialize_mipsread): Avoid initialization of importd
2339 global_psymbols and static_psymbols.
2341 * symfile.c (psymtab_to_symtab): Depend on XXX_psymtab_to_symtab
2342 to properly set pst->symtab; avoid searching for it.
2343 (symfile_fns): Improve comments, add a FIXME.
2344 * dbxread.c: Update comments to reflect symfile protocol.
2345 (read_ofile_symtab, end_symtab): Return the symtab.
2346 (psymtab_to_symtab_1): Set pst->symtab.
2348 * coffread.c (coff_symfile_read): tell condense_misc_bunches
2349 whether we're mainline.
2351 * symfile.h (sym_fns): Remove unused sym_discard member.
2352 * coffread.c, mipsread.c, dbxread.c: Remove XXX_symfile_discard.
2354 * mtrace.c (mtrace): Take effect if mallwatch is set, even if
2355 the environment variable is not.
2356 * infcmd.c (finish_command): Use filtered printfs.
2357 * cplus-dem.c: Add struct tags to a few unnamed structs.
2358 * valops.c (value_coerce_array): Improve comments.
2359 * valprint.c (type_print_varspec_suffix): Print array size only
2360 if greater than zero.
2361 * m88k-tdep.c: Shift some lines left by one space, that had
2362 apparently been trashed at some point.
2363 * TODO: More things to do, a few got done.
2365 Thu Jul 18 22:46:05 1991 John Gilmore (gnu at cygint.cygnus.com)
2367 * symtab.h (LOC_EXTERNAL): Eliminate in favor of LOC_STATIC.
2368 (ldsymoff, ldsymlen, globals_offset, statics_offset): Improve
2370 * dbxread.c (read_dbx_symtab): LOC_EXTERNAL -> LOC_STATIC.
2371 * expread.y, findvar.c, symmisc.c: Ditto.
2372 * printcmd.c (address_info): Update printed forms of LOC_
2373 symbols. Elim LOC_EXTERNAL.
2374 (print_frame_args): Keep track of param stack offsets before
2375 re-looking up to find the local register param is kept in.
2377 * mipsread.c: Use <symconst.h> and <sym.h> rather than <syms.h>.
2378 Further integration of mipsread into gdb. Eliminate unused
2379 routines, duplicate declarations. Handle static symbols in
2380 psymtabs as well as external symbols. When reading symtabs,
2381 insert symbols into the correct block (global, static, or a local
2383 (read_mips_symtab, parse_partial_symbols): Don't pass useless
2385 (mipscoff_symfile_read): Don't call select_source_symtab.
2386 (parse_symbol): Use SYMBOL_VALUE_ADDRESS where appropriate,
2387 rather than SYMBOL_VALUE.
2388 (parse_external): Comment clobbering of top_stack.
2389 (parse_partial_symbols): Update comments. Allocate and parse
2390 static symbols as well as external symbols. FIXME, enum values
2391 are not handled in this pass, but should be. Inline new_psymbol.
2392 Use SYMBOL_VALUE_ADDRESS.
2393 (psymtab_to_symtab_1): Read symbols into global static block
2394 by default (until enter some function's local block context).
2395 (sort_blocks): Clean up STATIC_BLOCK as well as GLOBAL_BLOCK.
2396 (destroy_all_symtabs, new_psymbol): Eliminate, unused.
2398 * source.c (select_source_symtab): Select a source symtab
2399 from either the symtabs or, failing that, the psymtabs.
2400 (list_command): Update error message.
2401 (forward_search_command, reverse_search_command): Use getc, not
2402 fgetc, for speed. FIXME, add comment about buffers that die if
2403 overrun by long line.
2405 * values.c (unpack_field_as_long, modify_field): Avoid shifting
2406 by an entire word, which is not portable, if we have a 32-bit
2407 field. (Code in dbxread.c already turns such bitfields, if
2408 aligned, into ordinary ints, but fixing this will help for other
2409 symbol formats and for future changes.)
2410 * core.c (core_open): Handle ANSI const brain death.
2411 * utils.c (vprintf): Fix varargs typo.
2413 Sun Jul 14 00:42:53 1991 John Gilmore (gnu at cygint.cygnus.com)
2415 * findvar.c (find_var_value): Handle &function better.
2416 * TODO: Document work needed on &fn and &array.
2417 * printcmd.c (print_address_symbolic): New arg is the prefix
2418 to print if a name is printed.
2419 (print_address_demangle): Honor "set print address" now.
2420 Use new arg above to improve spacing of output.
2421 * valprint.c (val_print): When printing function pointers,
2422 print symbolic form too.
2423 * breakpoint.c (breakpoint_1): Use new print_address_symbolic.
2425 Mon Jul 8 19:02:46 1991 John Gilmore (gnu at cygint.cygnus.com)
2427 * core.c (memory_error): Reword error msg to mislead less.
2429 * mips-pinsn.c (print_insn_arg 'd'): Print $ with reg name.
2431 * mipsread.c (read_mips_symtab, read_the_mips_symtab,
2432 parse_partial_symbols): Use newer BFD internals (external_filehdr
2433 and external_aouthdr), byte-swap the fields that we care about
2434 before using them, and make the file header data local to
2435 read_the_mips_symtab rather than global.
2437 Sat Jul 6 01:34:15 1991 John Gilmore (gnu at cygint.cygnus.com)
2439 * ns32k-opcode.h (movmw, movmd): Fix opcodes. Bug fix
2440 from Rune Nerg}rd <runene@ifi.uio.no> on 5 Jul 1991.
2442 * main.c (command_line_input): Flush stdout and stderr
2443 before every call to readline. This reportedly fixes a bug
2444 that comes up in Sys V running emacs-gdb and/or xxgdb,
2445 when stdin/out are pipes or sockets.
2447 Thu Jul 4 14:47:06 1991 John Gilmore (gnu at cygint.cygnus.com)
2449 * configure.in, Makefile.in: Avoid rebuilding "depend" as much.
2450 Avoid declaring Makefile dependencies, because GNU Make stupidly
2451 tries to update it if we do.
2453 * coffread.c: Revise for minor changes to bfd internal coff
2456 * configure: If -template= is given a relative path, make it
2457 absolute before recurring in subdirectories.
2459 * configure, configure.in, Makefile.in: Install "configure" script
2460 as replacement for config.gdb.
2461 * config.gdb, Makefile.dist, Makefile.sdir: Remove
2462 * README: Update for configure, mostly. FIXME.
2464 * Add dec3100 as equivalent to littlemips. Indicate in all host &
2465 target config files that they are for the host. When the lines
2466 get copied into the Makefile, this makes it more obvious what's
2469 Mon Jun 24 23:49:07 1991 John Gilmore (gnu at cygint.cygnus.com)
2471 * sparc-opcode.h (trap opcodes): Avoid leading spaces or
2472 tabs, which end up in the disassembler output inadvertently.
2474 Wed May 29 23:01:03 1991 John Gilmore (gnu at cygint.cygnus.com)
2476 Make it compile cleanly in an ANSI GCC2 environment.
2478 * blockframe.c: <stdio.h>
2479 * cplus-dem.c: free takes a void *, ifdef __STDC__
2480 * dbxread.c (read_huge_number): avoid gcc2 bug hoisting calc of
2482 * defs.h (alloca): Avoid doing anything if alloca already def'd.
2483 * stddef.h, stdlib.h: Remove these files.
2484 * symtab.c: Avoid declaring qsort, close.
2485 * symfile.c: Avoid declaring close.
2486 * utils.c (vprintf): Declare "ap" arg as proper va_alist.
2487 * sparc-tdep.c: Avoid including lots of Sun-host-specific files.
2489 Assorted other changes.
2490 * dbxread.c: include "libaout.h", not "liba.out.h".
2491 * printcmd.c (print_frame_args): Set recurse properly for
2492 indentation of struct and array parameters.
2493 * valops.c (value_cast): Allow cast to void.
2494 * infrun.c (resume): If NO_SINGLE_STEP, call machine dependent
2495 single_step() in a target-independent fashion.
2496 * sparc-tdep.c (single_step): Don't call ptrace ourselves, just
2497 set up to be ready to continue. This makes us target independent.
2498 * infptrace.c (child_resume): Remove call to single_step; now
2499 can single step a SPARC target of any kind.
2501 Wed May 22 18:18:24 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
2503 * Makefile.dist, doc/gdb.texinfo, doc/*-m4.texinfo: split up GDB
2504 docn into separate sections---basically chapters, plus two loose
2505 pieces that can be configured to go in different places. This
2506 allows GNU m4 to preprocess the manual without coredumping.
2508 * Makefile.dist: tell TeX where to find texinfo.
2510 Mon May 20 12:15:04 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
2512 * Makefile.dist, doc/gdb.texinfo: respectively create, and use,
2513 the new target "rdl-apps.texinfo" which captures the Makefile
2514 variable that records where to find the Readline libraries.
2516 Sun May 19 05:36:59 1991 John Gilmore (gnu at cygint.cygnus.com)
2518 * tahoe-pinsn.c: #include "tahoe-opcode.h", not "opcode.h".
2519 * tm-tahoe.h (FIX_CALL_DUMMY): Ignore more parameters.
2520 * defs.h (const, volatile): Only define if not already defined.
2521 * Makefile.dist (gdb.tar.Z): Create doc subdir w/out CVS/RCS crud.
2523 * README: Update for release 3.95.
2524 * config.gdb: Don't create readline dir in subdir builds.
2525 * main.c: Include with "..." form for non-system include files,
2526 so "gcc -MM" for "make depend" works.
2527 Include readline files with "...h" rather than <readline/...h>.
2528 * mipsread.c: Include "ecoff.h" rather than "intel-coff.h".
2530 * coffread.c: Undo minor damage done by Rich Pixley. Use
2531 different internal and external representations of COFF
2532 data structures. Use new BFD routines for swapping them in and
2534 * symfile.c (free_named_symtabs): Avoid freeing file names that
2535 are null or empty. Old i960 tools seem to produce files that
2536 claim to have empty names, causing each successive file read
2537 to blow away the previous one.
2538 * sparc-xdep.c (deferred_stores): Repair minor damage by Rich.
2539 Move deferred_stores to top of file, but don't separate its
2540 #define's from its variable. Add commentary.
2541 * Makefile.dist: Fix Rich damage; undo "configure" changes in
2542 favor of keeping the (working) config.gdb. Move readline
2545 Fri May 17 12:49:56 1991 Per Bothner (via gnu at cygint.cygnus.com)
2547 * dbxread.c (read_struct_type): Try to handle g++ version 1 MI
2549 * infptrace.c (fetch_registers): no result, since now void.
2550 * tconfig/news: target depends on m68k-tdep too.
2552 Fri May 17 14:40:14 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
2554 * Makefile.dist: added readline/inc-*.texinfo to dependencies for
2557 * readline/inc-history.texinfo, readline/inc-readline.texinfo:
2558 applied various small fixes due to or inspired by RMS comments
2560 * doc/gdb.texinfo: finished using all RMS comments, save those for
2561 appendices on readline and cmd history (which are in other source
2564 Thu May 16 18:06:05 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
2566 * doc/gdb.texinfo: (1) Updated w/ref to RMS comments through
2567 chapter 9; (2) documented 'break' command's menu mode for
2568 overloaded names, in response to hgs problem report C++ p-31
2570 Wed May 15 11:02:48 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
2572 * doc/gdb.texinfo: (1) better introductory example; (2) more
2573 consistent use of @code, @samp, @file, @kbd throughout; small
2574 cleanups to first three nodes; (3) new "Contributors" node;
2575 (4) Appendix, Renamed Commands; (5) divert specialized startup
2576 instructions to "Targets" chapter for generic manuals, while
2577 leaving them up front for manuals specific to specialized
2578 environments; (6) apply fixes from RMS comments through chapter 4.
2580 * pretex.m4: modify explanatory text slightly (and redefine
2581 "regexp") to keep GNU m4 from complaining. (It still crashes
2582 later, but one step at a time...)
2584 Wed May 15 10:32:12 1991 John Gilmore (gnu at cygint.cygnus.com)
2586 * readline/readline.c (update_line): Avoid dereferencing a pointer
2587 before comparing it to its bounds. Saber caught this.
2588 (init_terminal_io): Don't set BC from the "pc=" termcap variable,
2589 and only set PC if tgetstr returned non-null. Saber caught this.
2591 Tue May 14 16:29:53 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)
2593 * Makefile.dist: put gdb.dvi stuff (updated to use M4 preprocessor
2594 stuff for config manual) here where it counts; updated
2595 to use new subdir structure (gdb/doc/).
2597 * Makefile: generated from above via
2601 * gdbint.texinfo: added instructions on generating gdb.info* files
2602 locally for release. These are ordinary info
2603 files, formatted from gdb.texinfo (via gdb-all.texinfo, see
2604 Makefile)---but due to use of texinfo 2, can't count on makeinfo
2605 to generate these, so we distribute them already formatted.
2607 * gdb.texinfo: included full Info node and menu crud (as generated
2608 by C-u M-x texinfo-master-menu using the texinfo-2 elisp code).
2610 * Makefile: updated "gdb.dvi" target to use M4 preprocessor;
2611 put in comments-for-future gdb.info target (one day makeinfo will
2614 Tue May 14 13:51:36 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)
2616 * gdb.texinfo: Updated to include new or old undocumented
2617 commands, at least the following (perhaps some others I forgot to
2618 record): info f, info float, info path, info program, info s, info
2619 set, info source, info terminal, info types, info user, set/show
2621 Also covered all recent GDB command renames for v4.
2623 Mon May 13 14:57:46 1991 John Gilmore (gnu at cygint.cygnus.com)
2625 * mipsread.c: Rather than keeping count of how many symtabs
2626 and psymtabs we have, for sorting purposes, count them when
2627 we need to sort. This fixes bug in rereading of symbol tables.
2629 Fri May 10 15:43:33 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)
2631 * infcmd.c: renamed "info path" to "show paths"

2645 * coffread.c, exec.c, infptrace.c, inftarg.c, remote.c, solib.c,
2646 symtab.h, target.c, target.h: Lint.
2647 * core.c: setup and select frame after reading shared libs,
2648 else reading shared libs will clobber them. Lint.
2649 * utils.c (error): Force out any buffered wrap text.
2651 Fri May 3 22:01:56 1991 John Gilmore (gnu at cygint.cygnus.com)
2653 * remote.c: Remove decls of memory_insert_breakpoint
2654 and memory_remove_breakpoint, no longer used. (Suggestion of
2657 * Makefile.dist: use ${subdir} in paths of BFD and LIBIBERTY,
2658 to make it easier to interface to "configure"'d libraries.
2660 Fri May 3 13:10:01 PDT 1991 Roland Pesch (pesch at fowanton.cygnus.com)
2662 * valprint.c: introduce "set p", "set pr", "show p" and "show pr" as
2663 aliases for set/show print.

2752 * infptrace.c (PT_WRITE_D, PT_READ_D): Use correct values.
2753 (This still doesn't seem to make MIPS bkpts work.)

2791 not {value_as,unpack}_long on CORE_ADDR's.
2792 Use longest_to_int (added to defs.h) instead of cast to int.
2793 Remove from_tty arg to mod_path.
2794 Put symfile_bfd in {coff,dbx}read.c not symfile.h.
2795 Use OP_NULL instead of 0 where dummy enum exp_opcode needed.

2870 rather than smash_to_method_type.
2871 symtab.c, symtab.h (allocate_stub_method): New function.

3214 * dbxread.c (read_dbx_symtab): Allow N_SOL to cleanly take us back
3215 to the main file, as well as to include files. Also, put global
3216 functions into the global psymtab, to make "i fun" work.
3217 (end_psymtab): Free named symtabs and psymtabs for a file, once a
3218 new psymtab for it has been read.
3219 * coffread.c (end_psymtab): Free named symtabs and psymtabs for
3220 a file, once a new symtab has been read for it.
3221 * mipsread.c: FIXME. We need to do the same for MIPS, but it

3223 queued to the psymtab list.
3225 * symfile.c (symbol_file_add): Use filtered printing and wrap it.
3226 If we have wiped out any old symbol tables, clean up at end of

3242 static psymbols list.
3243 (types_info): Restore this function from its untimely #if 0.

3266 (dbx_psymtab_to_symtab): symfile might be zero, cope.
3267 * exec.c (exec_ops): Add_syms_addr is valid in our tvec.
3268 (set_section_command): New command ("section xxx yyy" -- should
3269 be renamed to "set section xxx yyy" FIXME) which sets the
3270 base address of a section of the exec file, overriding the
3271 virtual address that BFD reports.
3273 Fri Apr 5 17:14:39 1991 John Gilmore (gnu at cygint.cygnus.com)
3275 * exec.c: Add add_syms_addr_command to exec_ops, so you can

3280 * tm-i386v.h (FLOAT_INFO): Don't define it, since the code
3281 for printing the float info is host-dependent, not
3282 target-dependent. FIXME.
3283 * i386-pinsn.c: Move #includes to top, remove useless ones.
3284 * i386-tdep.c: Don't bother including <.../reg.h> since we
3285 don't use it (and it doesn't exist on host systems).
3287 * ieee-float.c (ieee_extended_to_double): Convert NaN to Inf.
3288 Convert negative numbers properly.
3289 (ieee_test): Make numbers really random; fix format arg.
3291 * infcmd.c (attach_command, detach_command): Don't repeat on CR.
3292 * core.c (core_detach): Unpush core_ops, which might not be on

3294 need dont_repeat() any more.
3295 (core_file_command): Psst! Don't repeat it.
3296 * remote-nindy.c (nindy_detach): Don't need dont_repeat() now.
3297 * expprint.c (print_subexp): Avoid switch fallthru on
3298 BINOP_ASSIGN_MODIFY, so we can print += and such.
3299 * frame.h: Fix typo.
3300 * inflow.c (kill_command): After killing inferior, print our
3301 current frame in the core file, if we have one.
3302 (generic_mourn_inferior): When inferior dies, either select
3303 the current frame (in the new target, e.g. core file), or
3304 set both the current and selected frames to NULL.
3306 Changes from Peter Schauer.
3308 * infptrace.c: Avoid <sys/ptrace.h> on USG.
3310 * Make all file names fit in 14 characters (sigh and damn!):
3311 mv hp300hpux-xdep.c hp300ux-xdep.c
3312 mv symmetry-xdep.c symm-xdep.c
3313 mv symmetry-tdep.c symm-tdep.c
3314 mv convex-opcode.h convx-opcode.h
3315 mv tm-vxworks960.h tm-vx960.h
3316 mv tm-vxworks68.h tm-vx68.h
3317 mv Makefile.srcdir Makefile.sdir
3318 mv gdb-int.texinfo gdbint.texinfo
3319 mv remote-sa.m68k.shar rem-m68k.shar
3320 mv remote-multi.shar rem-multi.shar
3321 * Makefile.dist, README, config.gdb, convex-pinsn.c,
3322 tconfig/symmetry, tconfig/vxworks960, tconfig/vxworks68,
3323 xconfig/hp300hpux, xconfig/symmetry: Change names to shorter
3326 * command.c (user_info_1, user_info): New command for listing
3327 the user-defined commands.
3329 Wed Apr 3 15:00:26 1991 John Gilmore (gnu at cygint.cygnus.com)
3331 * dbxread.c (really_free_pendings): Clear file_symbols
3332 and global_symbols after freeing them; otherwise, running
3333 this function twice (if it appears twice on the cleanup
3334 chain), we try to free things twice.
3336 * dbxread.c (read_dbx_symtab): Calculate end_of_text_addr
3337 based on text_addr (the address of text in core), not on addr (the
3338 offset between text in the .o file and in core). This change
3339 is from Peter Schauer.
3341 * main.c: Define ALL_CLEANUPS as a cast of zero.
3342 (return_to_top_level): Use it.
3343 (main): Do all cleanups after each command run as part
3344 of the gdb startup sequence. Also do all cleanups before
3345 entering the command loop, and every time we exit the command
3346 loop and reenter. Before, the cleanups from the startup sequence
3347 were being left undone until the first error!
3348 (command_loop): Rename do_nothing cleanup to command_loop_marker
3349 so we can see it easily when examining the cleanup chain.
3350 (init_signals): Add another do_nothing for signal handling.
3351 (quit_command): Only try to kill target if it has execution.
3352 Problems in the target stack got us into a state where
3353 inferior_pid was nonzero but none of the targets had execution.
3354 In this state you couldn't exit gdb.
3356 * dbxread.c: Two changes from Peter Schauer.
3357 (echo_command): Fflush output after an echo command.
3358 (show_history): Pass all args to cmd_show_list.
3360 * utils.c (init_malloc): Call mtrace to turn on tracing
3361 if the environment variable MALLOC_TRACE is set to a file name.
3362 * mtrace.c: Add source file which provides a log of every malloc,
3363 free, and realloc to a trace file.
3364 * mtrace.awk: Add source file which analyzes the trace file.
3365 * Makefile.dist (GNU_MALLOC, MALLOCSRC): Add mtrace.{c,o,awk}.
3366 (VERSION): Roll to 3.94.3.
3368 * breakpoint.c (breakpoint_1): Add a space to "i watch" output.
3369 (check_duplicates): Don't bother with watchpoints.
3370 (set_raw_breakpoint): Comment about danger of this routine.
3371 (watch_command): Parse and eval all args before calling
3374 * solib.c (find_solib): Avoid error in referencing memory to
3375 see if any more shared libraries have been added. This is
3376 particularly useful if the target has terminated. Bug reported
3379 Changes from Peter Schauer <pesrem@regent.e-technik.tu-muenchen.de>
3380 in bringing up 3.94.2 on the Sun-3.
3382 * Makefile.dist: Include CFLAGS in rule for cplus-dem.o.
3383 * breakpoint.c (enable_breakpoint): Check for valid watchpoint
3384 expression (in scope) before reenabling watchpoint.
3385 * signame.c (init_sigs): Add missing declaration of i, fix
3386 sys_siglist declaration.
3387 * source.c (list_command): Fixed range computation to use
3389 * stack.c (backtrace_command): Do not allow command if target has
3390 no stack, print informative error message.
3391 * target.c (target_command): Do not write into command line
3392 because this fails if the target command is used in a user defined
3393 command. [This change was enhanced by gnu to support any-
3394 unique-prefix matching on target names.]
3395 * valops.c (value_struct_elt): Avoid infinite loop on an
3396 erroneous attempt to print the member of function (try p main.p).
3398 Mon Apr 1 17:05:45 1991 John Gilmore (gnu at cygint.cygnus.com)
3400 * expread.y (name_no_typename): Avoid reduce/reduce errors
3401 caused by ambiguity in handling NAME_OR_INT and NAME_OR_UINT.
3402 Since the GDB parser really doesn't use name_no_typename in a
3403 name-only context, the parser can't tell the diff between
3404 names and numbers here. Avoid allowing a name_no_typename
3405 to be a NAME_OR_*INT to resolve the conflict.
3407 Sun Mar 31 20:12:07 1991 John Gilmore (gnu at cygint.cygnus.com)
3409 Bugfixes from Mark Fox (markf@wrs.com) (test=testField.c):
3411 * valprint.c (val_print_fields): bitfield printing didn't handle
3412 byte order. Indirect through a few more fns to cope.
3414 * values.c (modify_field): also cope with byte order.
3416 Sat Mar 23 10:02:21 1991 John Gilmore (gnu at cygint.cygnus.com)
3418 Cleanup for release 3.94.2:
3420 * Makefile.dist: Pull REMOTE_OBS. Fix saber includes for BFD
3421 include files. Roll version to 3.94.2.
3423 * coffread.c (init_stringtab): Read length into unsigned char
3424 array before swapping; don't assume 32-bit longs.
3426 * target.c (target_info): Don't bother with get_sym_file, just use
3427 the symfile global variable.
3428 * symtab.h, symfile.c (get_sym_file): Delete it.
3430 * dbxread.c (dbx_symfile_init): Don't depend on long == 4 bytes.
3431 (define_symbol): Set symbol line number to 0 if not gcc-compiled.
3432 (read_type): Replace one more error() with complain().
3434 * mipsread.c (parse_partial_symbols): Replace printf with complain.
3436 * i960-tdep.c: Fix copyright attribution.
3438 * config.gdb: Quote all backquotes in doublequotes. You can
3439 quote me on that. BSD 4.4 shell found this one.
3441 * infptrace.c (throughout): The third argument to ptrace is an
3444 * infrun.c (wait_for_inferior): When program has terminated, we
3445 have to call target_terminal_ours before we pop that target off
3446 the stack (e.g. before a call to target_kill or
3447 target_mourn_inferior). This fixes problem where a program
3448 terminates, then GDB stops for (tty output) and you have to type
3449 "fg" to the shell to resume it. FIXME: This code for what to
3450 do after termination really should be in normal_stop instead.
3452 * gdbcore.h (read_memory_check): Change declaration; it changed
3455 * terminal.h: Include <sgtty.h> before <sys/ioctl.h>, since in BSD
3456 4.4 prereleases, this avoids a bug in their sgtty compatability
3458 * remote.c: Use terminal.h rather than hand-rolling the same.
3460 * signame.c, signame.h (psignal): Arg is unsigned, not int.
3461 * utils.c (strsave, strstr): Fix arg types.
3462 * valprint.c (val_print): lint
3464 MIPS symbol table support from Per Bothner:
3466 * symfile.c (symtab_fns): Remove initializer table that needs to
3467 be hacked for each new symbol file format supported.
3468 (add_symtab_fns): New function, chains symbol table
3469 handlers into the global list.
3470 (symfile_init): Search this list.
3471 * symfile.h: Add next pointer, declare add_symtab_fns.
3472 * coffread.c (_initialize_coffread): Call add_symtab_fns.
3473 * dbxread.c (_initialize_dbxread): Call add_symtab_fns.
3475 * mipsread.c (psymtab_to_symtab_1): return void instead of (struct
3476 symbol *). Thus, we no longer need the hack to trash
3477 pst->filename. Good, since that hack confused code in symfile.c!
3479 (reorder_symtabs, destroy_all_symtabs): Removed static
3480 all_symtabs, which was used to qsort symtabs in reorder_symtabs.
3481 Instead, the latter now uses a temporary array (stack-allocated
3482 from an obstack, and then freed).
3484 (parse_symbol): Added a hack to fix up BLOCK_{START,END} if they
3485 haven't been set in the outermost stBlock of a procedure. This was
3486 a problem with f77 binaries on Ultrix 4.?.
3488 (new_symtab, new_symbol, new_type): Continue changing code to use
3489 obstacks more and otherwise conform to dbxread internal style.
3490 Made the free_code of symtabs be free_linetable (as in dbxread)
3491 instead of free_contents. This implies memory leaks when reading
3492 a new symbol table, until the conversion is finished. Did change
3493 (struct symbol) and (struct type) to be allocated on the
3494 symbol_obstack. Blocks and blockvectors are among the things
3497 * mipsread.c (parse_partial_symbols, parse_fdr): It hasn't been
3498 tested much, but it solved one problem (reported by Meissner), and
3499 cleans up some other things. The problem happened when an
3500 included file contains actual code (functions) and not just
3501 definitions. The mips coff is a little inconvenient there, since
3502 it may cause a procedure to be mapped to the wrong psymtab.
3504 * mips-tdep.c (heuristic_proc_desc): Minor cleanup.
3505 * mips-xdep.c (fetch_core_registers): Minor cleanup. FIXME,
3506 this will need work for the new core paradigm.
3508 Opcode patches from the net:
3510 * mips-opcode.h: fix incorrect disassembly of the mfc1, cfc1, and
3511 ctc1 instructions. Also, the cvt.d.w and cvt.s.w instructions were
3512 missing altogether - they are added here. From Bruce Bauman.
3513 * mips-opcode.h: The low mask for C0 instructions was too small.
3514 From Garrett Lau. I modified the fix to check the entire 32-bit
3517 * ns32k-opcode.h: Fix opcodes for deiw and deid. From Bruce
3520 Thu Mar 21 12:56:46 1991 John Gilmore (gnu at cygint.cygnus.com)
3522 Roll in changes from Per Bothner (Tue, 25 Sep 90 11:11:04):
3524 * dbxread.c (read_type): Pointer subtraction (value_sub in
3525 valarith.c) sometimes failed because the types of the
3526 pointers being subtracted were not identical.
3527 These differed because dbxread.c was allocating pointer types
3528 using dbx_alloc_type+smash_to_pointer_type instead of
3529 lookup_pointer_type. I failed to find a justification for the
3530 former, so I changed it to use the latter. Similarly, I
3531 replaced smash_to_function_type by lookup_function_type,
3532 and smash_to_reference_type by lookup_reference_type.
3534 * mipsread.c (parse_symbol, upgrade_type, parse_procedure,
3535 _initialize_mipsread): corresponding changes.
3537 * symtab.c (smash_to_{pointer,reference,function}_type): eliminate.
3539 * source.c (mod_path): Do tilde_expand on each component of the path,
3540 rather than on the (list of) paths as a whole.
3541 (print_source_lines): Set first_line_listed in addition to
3542 current_source_symtab and current_source_line. If the source was
3543 not findable, after a "dir" command to fix the problem,
3544 a "list" would get the wrong lines.
3546 While I was there... (gnu):
3548 * dbxread.c (read_type): Change error to complaint.
3550 Thu Mar 21 12:56:46 1991 John Gilmore (gnu at cygint.cygnus.com)
3552 First attempt at detailed understanding of symbol table memory alloc.
3554 * dbxread.c (dbx_symfile_read): Free our string table if we
3555 aren't the mainline. Free the "info" struct since we're done with
3557 (init_psymbol_list): Free any previously allocated psymbol lists.
3558 (): FIXME: Should realloc-down the psymbol lists when done reading
3559 the main symbol file?
3561 * symmisc.c (free_symtab): Free fullname field too.
3563 * xm-hp300hpux.h (USG): #undef then #define so Makefile can -D.
3564 (REGISTER_ADDR): Make result type unsigned int.
3566 * xconfig/{i386*,hp300hpux,altosgas,altos}: All config files that
3567 define REGEX must also define REGEX1 (its dependency).
3569 Tue Mar 19 21:28:57 1991 John Gilmore (gnu at cygint.cygnus.com)
3571 * tconfig/i960: No longer works, points you at vxworks960 or
3574 * xgdb.c, XGDB-README: Remove file. Users can get the much
3576 * Makefile.dist: Remove all trace of xgdb.
3578 * breakpoint.c (breakpoint_1): Pass demangle arg to
3579 print_address_symbolic.
3580 (clear_breakpoints): Remove unused function.
3581 (breakpoint_re_set_one): Guts of breakpoint_re_set.
3582 (breakpoint_re_set): Use catch_errors to do them all anyway.
3584 * gdb-int.texinfo (Host versus Target): Add section on what is
3585 a "host" feature versus what is a "target" feature.
3587 * infcmd.c (path_command, path_info): Handle the PATH variable
3588 (object search path) as conveniently as the source search path.
3589 * environ.c (set_in_environ): Set some vars in GDB's environment,
3590 in addition to the child's. PATH, G960BASE, G960BIN for starters.
3591 * source.c (mod_path): New function, from guts of
3592 directory_command, modifies a path. Used by path_command.
3593 (directory_command): Call it.
3594 * defs.h (strsave): Declare.
3596 * utils.c (sevenbit_strings): Add new printing option.
3597 (printchar): Use it.
3598 (strsave): Provide this handy helper routine.
3599 (set_width_command): Rename set_screen_width_command.
3600 (_initialize_utils): "set screen-width" => "set width";
3601 "set screen-height" => "set height"; add sevenbit-strings.
3603 * infcmd.c (do_registers_info): Print floating point registers
3604 in raw hex as well as float format, regardless of whether it is
3605 a "virtual" convertible register.
3606 * tm-sparc.h (PRINT_REGISTER_HOOK): Print every pair of float
3607 regs as a double, just in case it's being used that way.
3608 * values.c (unpack_long): Comment on array/function coercion.
3609 (unpack_double): Argument is in target byte order now. For
3610 integer arguments, just call unpack_long and float the result.
3611 * m68k-tdep.c: include defs.h for "const" handling.
3612 * remote-nindy.c: Use ieee-float stuff.
3613 (nindy_fetch_registers): Unpack double regs to host double, then
3615 (nindy_store_registers): Pack extendeds to host double, flip
3616 around by misusing unpack_double, send as target double.
3618 * tm-vxworks68.h (FRAME_CHAIN): Handle current frame pointer of
3619 zero, as when stopped at the first instruction of a process.
3621 * blockframe.c: Fix filename in comment (param.h => tm.h).
3622 * sparc-tdep.c (skip_prologue): More explicit nudging comments.
3623 * tm-68k.h: Fix typos.
3625 Fri Mar 15 01:09:34 1991 John Gilmore (gnu at cygint.cygnus.com)
3627 Changes from a bringup on the DEC Vax under Ultrix 4.0.
3629 * coredep.c (fetch_core_registers): Pass end-address of register
3630 section to register_addr as expected. Don't call supply_register
3631 if we'd just pass it garbage.
3633 * dbxread.c (read_dbx_symtab): Skip N_NSYMS on Ultrix.
3635 * exec.c (xfer_memory): Use boolean xfer_fn result, not int.
3637 * target.c (push_target, target_info): Cast enums to int for < or
3640 * stack.c (print_frame_info): Identify source file & line
3641 even if we can't print it.
3643 * xm-vax.h (MISSING_VPRINTF): No longer missing in Ultrix V4.0.
3645 Sat Mar 9 10:08:20 1991 John Gilmore (gnu at cygint.cygnus.com)
3647 Clean up IEEE floating point support.
3649 * ieee-float.h: New file.
3650 * ieee-float.c: Write real routines to convert between host
3651 doubles and various target IEEE extendeds.
3652 * m68k-xdep.c: Eliminate assembler code for extended floats.
3653 * xconfig/{3b1,altos,altosgas,hp300bsd,isi,news,news1000,sun2os3,
3654 sun2os4,sun3,sun3os3,sun3os4}: Eliminate use of m68k-xdep.o.
3655 * tm-i960.h, tm-68k.h (REGISTER_CONVERT_TO_VIRTUAL,
3656 REGISTER_CONVERT_TO_RAW): Use ieee_extended_to_double and
3657 double_to_ieee_extended.
3658 * i960-tdep.c: Define ext_format_i960.
3659 * m68k-tdep.c: Define ext_format_68881.
3660 * sparc-tdep.c: Define ext_format_sparc, though unused.
3661 * Makefile.dist (HFILES): Add ieee-float.h.
3662 * inftarg.c: #include "ieee-float.h" for the REGISTER_CONVERT
3665 Obsolete the "coffstrip" program in favor of using BFD's strip.
3667 * nindy-share/coffstrip.c: Remove file.
3668 * nindy-share/nindy.c (coffstrip): Routine to run bfd_strip.
3669 * Makefile.dist: Remove references to nindy-share/coffstrip.c.
3670 * tconfig/nindy960: Remove reference to coffstrip.o.
3672 * Makefile.dist: Roll version number to 3.94.1 (not yet final).
3674 Wed Mar 6 09:56:45 1991 John Gilmore (gnu at cygint.cygnus.com)
3676 * symfile.h: Add symfile_bfd, common between dbxread and coffread.
3677 * dbxread.c: Remove static symfile_bfd.
3678 * infcmd.c (do_registers_info): Add PRINT_REGISTER_HOOK, though
3680 * inftarg.c (child_detach): Pop the child_ops vector if the
3681 detach is successful.
3682 * remote-nindy.c (nindy_create_inferior): Don't push a new
3683 nindy_ops since nindy uses the same one for execution and memory
3685 * core.c (core_ops): Use child_attach and child_create_inferior
3686 rather than default attach and create_inferior functions.
3688 Handle floating point registers in core files.
3690 * sparc-xdep.c (fetch_core_registers): Rewrite for float support.
3691 * sun3-xdep.c (fetch_core_registers): Rewrite for float support.
3692 This version untested since BFD doesn't yet support sun3 core
3694 * hp300hpux-xdep.c: Rewrite fetch_core_registers to new calling
3695 conventions. Fix comments and style. This version has not
3696 been compiled yet, since we have no HP inhouse.
3697 * core.c (get_core_registers): Look for two sections, ".reg"
3698 and ".reg2", and pass both to fetch_core_registers sequentially.
3700 Revise directory path yet again.
3702 * source.c (forget_cached_source_info): Not static any more.
3703 (init_source_path): New default source path is "$cdir:$cwd".
3704 (dir_command): Handle variable arguments ($cdir, $cwd).
3705 (source_info): Print "Compilation directory" rather than
3706 "Originally compiled in" to remind people of $cdir.
3707 (openp): If the path contains $cwd, use current directory.
3708 (open_source_file): If compilation directory is known, replace
3709 first $cdir in path with the compilation directory.
3710 (print_source_lines): Even if we can't print the lines, set the
3711 current symtab and line for future commands like "info source" or
3712 "breakpoint". Also, error message now contains the file name,
3713 line number, and file access error message.
3714 (_initialize_source): Fix help text to describe changes.
3715 * main.c (cd_command): Forget cached source info when we chdir.
3716 * utils.c (strstr): Add simple implementation.
3718 Tue Mar 5 01:41:40 1991 John Gilmore (gnu at fowanton.cygnus.com)
3720 * coffread.c (read_one_sym, init_linetable, init_stringtab):
3721 Byte-swap COFF symbol tables if necessary when reading them in.
3722 Use complain() to replace error message in one spot. Needs
3723 corresponding change in bfd/coff-code.h to make some symbol
3724 swapping routines non-static.
3726 Mon Mar 4 00:53:40 1991 John Gilmore (gnu at cygint.cygnus.com)
3728 Merge changes from Eirik Fuller, for UTek.
3730 * defs.h (errno): Add declaration.
3731 * altos-xdep.c, arm-xdep.c, convex-xdep.c, gould-xdep.c,
3732 hp300hpux-xdep.c, infrun.c, inflow.c, infptrace.c, i386-tdep.c,
3733 i386-xdep.c, pyr-xdep.c, mips-xdep.c, remote-eb.c, remote-nindy.c,
3734 remote-vx.c, source.c, standalone.c, stuff.c, sun386-xdep.c,
3735 symmetry-tdep.c, symmetry-xdep.c, umax-xdep.c, utils.c: Eliminate
3736 declarations of errno.
3738 * remote-eb.c: Define B19200 and B38400 as EXTA and EXTB.
3740 * remote-vx.c: Include <sys/time.h> for UTek; Sun gets it via
3741 <rpc/rpc.h> and <rpc/types.h>.
3743 Sat Mar 2 15:47:55 1991 John Gilmore (gnu at cygint.cygnus.com)
3745 * i960-tdep.c (examine_prologue): Add new argument limit,
3746 which stops the scan at the end of the prologue, or at the PC.
3747 This fixes a problem where it walks down into the code for the
3748 user's statements if that code looks like function prologues.
3749 Mark Fox and I have been bouncing this code back and forth, making
3750 small changes to it. Callers changed to match.
3752 Tue Feb 26 01:47:07 1991 Cygnus John Gilmore (cygnus at yuba)
3754 Cleanup for gdb-3.94 release final:
3756 * Makefile.dist: Remove remote-vx.c, remote-nindy.c, and all
3757 the .c files from vx-share and nindy-share, from the various
3758 macros, since they are not found via ALLDEPFILES.
3759 (SFILES): Add tm-i960.h.
3760 (alldeps.mak rule): Break out ALLDEPFILES_MAINDIR and
3761 ALLDEPFILES_SUBDIR. List all the nindy and vxworks subdir files
3763 (TAGFILES_MAINDIR): Change ALLDEPFILES to ALLDEPFILES_MAINDIR.
3764 (gdb.tar.Z): Use ALLDEPFILES_SUBDIR as well as SFILES_SUBDIR.
3766 Mon Feb 25 16:02:35 1991 Cygnus John Gilmore (cygnus at oldman)
3768 * am29k-tdep.c: Add contribution line.
3769 (examine_prologue): Cache information about function prologues in
3770 the misc-function-vector to avoid lots of references over the
3771 serial line while examining instructions.
3773 * core.c (core_close): New function made from cleanup_core.
3775 * core.c, exec.c, inftarg.c, remote-eb.c, remote-nindy.c,
3776 remote-vx.c, remote.c, target.c, target.h,
3777 Update target_ops vector to add attach, close, and load entries.
3778 Use add_syms_addr_command, not add_file_addr_command, for
3779 add_file. Break out close routine from existing code.
3781 * dbxread.c (really_free_pendings): Don't free pending_blocks;
3782 they are in an obstack.
3783 (read_dbx_symtab): Relocate end_of_text_addr in the psymtab.
3785 (define_symbol): Add symbol type parameter; change callers;
3786 pass type parameter to DBX_PARM_SYMBOL_CLASS macro to allow
3787 it to influence the symbol class on the i960.
3788 (define_symbol): Swap LOC_CONST's into target byte order.
3790 * exec.c (exec_close): New function.
3791 (exec_file_command): Call it.
3793 * findvar.c (read_relative_register_raw_bytes): Doc byte order,
3794 Fix byte order of frame pointer.
3795 (read_var_value): Result of 0 if var's value can't be found,
3796 e.g. missing FRAME_ARGS_ADDRESS. Byte-swap LOC_CONST and
3797 LOC_LABEL values to target order. Add LOC_LOCAL_ARG.
3798 (locate_var_value): Use read_var_value and use its lazy address
3799 as the location of the var's value. Lint.
3801 * i960-pinsn.c (next_insn): Add routine from vxgdb for scanning
3804 * i960-tdep.c (arg_address, i960_frame_find_saved_regs): Remove
3805 obsolete Intel versions in favor of vxgdb versions.
3806 (check_host, byteswap, byteswap_val, reorder_val): Eliminate
3807 code dealing with byte order of values, which Intel did in host byte
3808 order rather than gdb-4's target byte order.
3809 (i960_frame_chain_valid): Move to nindy-tdep.c.
3810 (examine_prologue, skip_prologue, frame_find_saved_regs,
3811 frame_args_address, leafproc_return, saved_pc_after_call,
3812 pop_frame): Add vxgdb versions from Mark Fox.
3813 (examine_prologue, frame_struct_result_address): Add code
3814 to deal with the saved value of G13 (struct return address
3816 (frame_args_address): Modify Mark's version to prefer the
3817 saved value over the current value in the topmost frame.
3818 Cache result in the frame info to avoid performance hair in
3820 (print_fault): Add gdb960 code for printing faults.
3821 (_initialize_i960): Actually call check_host.
3823 * ieee-float.c (ieee_extended_to_double, ieee_double_to_extended):
3824 add stub routines. FIXME, these currently just return zero!
3826 * infcmd.c (program_info): Use PRINT_RANDOM_SIGNAL.
3827 (attach_command): Call target_attach, not target_open, now.
3829 * infrun.c (normal_stop): Make global, not static, for vx_attach.
3830 (child_attach): Rename from child_open.
3831 (wait_for_inferior): Use PRINT_RANDOM_SIGNAL. If stop_pc is zero,
3832 don't confuse it with a zero step_resume_break_address.
3834 * inftarg.c (child_detach): Eliminate inferior_pid test.
3835 (child_files_info): Clean up message a bit.
3836 (child_ops): Use child_attach, not child_open, to attach.
3838 * mem-break.c: #ifdef out the whole file if BREAKPOINT is not
3839 set (e.g. on VxWorks or NINDY). Move read_memory_nobpt from
3840 findvar.c to here, since it depends on the contents of the
3841 shadow_contents of breakpoints, but keep if #if 0 since it is
3844 * nindy-tdep.c: New file, contains nindy_frame_chain_valid, moved
3847 * printcmd.c (address_info): Handle LOC_LOCAL_ARG. Lint.
3848 (ptype_command, display_command): Eliminate have_inferior_p and
3849 have_core_file_p in favor of target_has_stack or
3850 target_has_execution.
3851 (print_frame_args): Handle LOC_LOCAL_ARG. Eliminate duplicate
3852 code for actually finding the values of arguments, though we still
3853 keep track of the maximum stack offset for use in printing unnamed
3854 arguments. Handle missing FRAME_ARGS_ADDRESS.
3856 * remote-nindy.c (i960_print_fault): Move to i960-tdep.c.
3857 (struct nindy_regs): Define registers passed to/from nindy.
3858 (nindy_fetch_registers, nindy_store-registers): Translate between
3859 nindy and GDB formats for the registers.
3860 (dcache_init): Statically allocate the cache, since it was being
3861 allocated by a malloc that was never freed anyway.
3862 (nindy_create_inferior): Error, not core dump, if no exec file.
3863 (nindy_before_main_loop): Use target_load, not target_add_file.
3865 * remote-vx.c (net_load): Specify large timeout for load
3866 requests. Allow user to break out with INTERRUPT.
3867 (net_break): Remove useless code, clean up. Change callers.
3868 (parse-args, skip_white_space, find_white_space): Clean up arg
3869 parsing to cope with quoted strings.
3870 (net_wait, net_quit): Never call error, just return status.
3871 (vx_read_register, vx_write_register): Cleanup status checking.
3872 #ifdef the code based on which CPU we are using (960 or 68k),
3873 FIXME, this should be completely general but it isn't yet.
3874 (vx_xfer_memory, vx_resume): Cleanup status checking.
3875 (vx_run_files_info): Improve message.
3876 (vx_load_command): Renamed from vx_add_file_command. Allow load
3878 (net_ptrace): Remove unused routine.
3879 (vx_wait): Adopt code from vxgdb960 to cope with broken
3880 connections to target machine and prompt to disconnect. Remove
3881 debug printouts. Map some EVENT_'s to SIGnals.
3882 (add_symbol_stub, vx_open): Print names of object files we found,
3883 and "ok" if we read their symbols OK. Clarify output in general.
3884 (vx_attach, vx_detach, vx_kill): Add these commands.
3885 (vx_convert_from_virtual, vx_convert_to_virtual): Simplify.
3886 (vx_run_ops): Turn off all_mem, to avoid spurious msg in the
3887 "info files" output, and create_inferior, since we already have
3890 * stack.c (frame_info): Replace Frame_unknown with 0.
3891 (print_frame_arg_vars): Handle LOC_LOCAL_ARG.
3892 (return_command): Pop until the PC matches as well as the FP,
3893 so it works even if the FP is shared with another function,
3894 as in "frameless" or "leaf" procedures.
3896 * symfile.c (load_command): renamed from add_file_target_command.
3897 (add_syms_addr_command): renamed from add_file_addr_command.
3898 (add_syms_command): Stub to call target_add_syms.
3899 (_initialize_symfile): Change command names and descriptions,
3900 add-file => add-syms, and load from alias to its own command.
3902 * target.c (kill_or_be_killed, maybe_kill_then_attach,
3903 maybe_kill_then_create_inferior): Default for attempts to start
3904 a process, if one is already running, is to ask about killing
3905 it and retry if yes.
3906 (upstack_create_inferior): #if-0 it, strata obsolete it.
3907 (push_target, unpush_target, pop_target): to_close() a target
3908 before unstacking it.
3909 (target_info): Renamed from target_files_info.
3910 (_initialize_targets): Rename "i files" as "i target", accessible
3913 * target.h: Improve comments about the target_ vectored routines.
3915 * tm-i960.h: Remove NINDY-specific stuff to tm-nindy960.h.
3916 Convert commenting style to standard GNU style.
3917 (DBX_PARM_SYMBOL_CLASS): allow LOC_LOCAL_ARG's to be recognized.
3918 (SKIP_PROLOGUE): No longer a no-op.
3919 (SAVED_PC_AFTER_CALL): Now handles leaf procedures.
3920 (*_REGNUM): Sort register numbers.
3921 (REGISTER_BYTES, REGISTER_BYTE, REGISTER_RAW_SIZE,
3922 MAX_REGISTER_RAW_SIZE, REGISTER_CONVERTIBLE,
3923 REGISTER_CONVERT_TO_VIRTUAL, REGISTER_CONVERT_TO_RAW): Float regs
3924 are now 10 byte extendeds, not 8 byte doubles.
3925 (FRAME_CHAIN_VALID): Make this config-dependent, since it differs
3926 for nindy versus vxworks targets. FIXME, this should possibly go
3927 in the target vector.
3928 (EXTRA_FRAME_INFO, INIT_EXTRA_FRAME_INFO): Cache both
3929 frame_saved_regs and arg pointer with each frame.
3930 (FRAMELESS_FUNCTION_INVOCATION): New leafproc support.
3931 (FRAME_ARGS_ADDRESS): Use cached result.
3932 (FRAME_ARGS_ADDRESS_CORRECT): New, avoids g14 guessing.
3933 (FRAME_FIND_SAVED_REGS): Change arg to subsidiary fn.
3934 (PRINT_RAMDON_SIGNAL): Call print_fault.
3935 (POP_FRAME): Now works.
3937 * tm-nindy960.h: Break this off tm-i960.h. NINDY-specific
3938 option parsing and startup; STACK_END_ADDR, FRAME_CHAIN_VALID,
3939 BREAKPOINT, and DECR_PC_AFTER_BREAK are here.
3940 (ADDITIONAL_OPTION_HANDLER): use target_load, not
3943 * tm-vxworks960.h: Break this off tm-i960.h. VxGDB specific
3944 startup; DECR_PC_AFTER_BREAK, and FRAME_CHAIN_VALID are here.
3946 * valarith.c (value_subscripted_rvalue): Avoid handling
3947 floats and doubles specially; it gave alignment errors. Lint.
3949 * valops.c (value_of_variable, value_of_this): Error if unknown
3952 * valprint.c (print_floating): Bcopy rather than pointer-deref,
3953 to avoid alignment problems.
3954 (value_print): Handle unknown value address.
3955 (cplus_val_print): Two args are ignored; remove them. Change caller.
3956 (val_print): Use unpack_long rather than pointer-deref.
3959 (unpack_long, unpack_double): Use bcopy rather than pointer-deref
3960 to avoid alignment problems.
3961 (value_being_returned): Error if return value unknown.
3962 (set_return_value): Add bogosity warning, FIXME. *
3964 * TODO: A woman's work is never done.
3966 * Makefile.dist: Distribute REMOTE_OBS into tconfig files.
3967 Separate INCLUDE_CFLAGS for use with lint. Add LINTFILES.
3968 Add ieee-float.o to OBS.
3969 * tconfig/{nindy960,vxworks68,vxworks960}: Include the desired
3970 REMOTE_OBS remote-interface files in the TDEPFILES and TM_FILE.
3971 * tconfig/i960: FIXME. Half-merge, produce warning if config'd.
3973 Changes to generalize the VxWorks RPC protocol slightly, to handle
3974 i960 as well as 68000.
3976 * vx-share/dbgRpcLib.h (VX_SOURCE_STEP): Add.
3977 * vx-share/reg.h: Produce i960 regs #ifdef I80960
3978 * vx-share/xdr_ptrace.c: Skip FPA registers if 960.
3979 * vx-share/xdr_rdb.h: Add SOURCE_STEP struct and xdr decl.
3980 * vx-share/xdr_rdb.c: Add xdr_SOURCE_STEP routine.
3981 * vx-share/xdr_regs.c: Add xdr_regs, xdr_fp_status, xdr_ext_fp
3982 for i960. Change xdr_vectors to xdr_opaques for 68k registers,
3983 so they will move in target byte order rather than network
3984 byte order (happens to be the same).
3986 Mon Feb 25 03:41:44 1991 John Gilmore (gnu at cygint.cygnus.com)
3988 * tm-convex.h (END_OF_TEXT_DEFAULT): Remove #if 0'd block.
3990 Sun Feb 24 00:55:53 1991 John Gilmore (gnu at cygint.cygnus.com)
3993 Add contribution lines to various files, showing where they
3996 * breakpoint.c (break_insn, check_break_insn_size,
3997 read_memory_nobpt): Remove to mem-break.c.
3999 * xm-*.h, param-no-tm.h, tm-29k.h, valprint.c: Change BYTE_ORDER to
4002 * tm-29k.h (STAB_REG_TO_REGNUM): Warn user if symbol table
4003 entry has bad register number. This change is not
4004 tested in this release, FIXME.
4006 * frame.h: Eliminate Frame_unknown in favor of a simple zero.
4009 * value.h: Force value's contents field to be aligned to hold
4010 at least a double or a long long (if supported). This avoids
4011 doing bcopy's in and out of the contents field.
4013 (step_1): Avoid coredump under obscure circumstances when we
4016 * symtab.h (misc_info): Add field to misc function vector for
4017 any kind of cached information the target code desires. AMD
4018 29000 uses this to avoid repeating examine_function_prologue's.
4020 * coffread.c: Lint. Remove static symfile, read_section_header.
4021 core.c (have_core_file_p): Lint: remove.
4022 expprint.c (print_subexp): Lint.
4023 infptrace.c, valops.c, valprint.c: lint.
4025 Roll in changes from vxgdb-5.0.1:
4027 * symtab.h: Comment byte order of each address class. Add
4028 LOC_LOCAL_ARG for frame-relative args (960).
4029 expread.y: Use LOC_LOCAL_ARG where LOC_ARG is used.
4030 symtab.c, symmisc.c: ditto.
4032 * infrun.c (init_wait_for_inferior): Clear stop_signal.
4034 * remote.c (remote_resume): Error if resume with a signal.
4036 * symfile.c (prim_record_misc_function): Clear misc_info.
4037 (fill_in_vptr_fieldno): Check stub type of arg.
4039 * valops.c (value_cast): Avoid looking up names of types whose
4040 name we don't know, to prevent coredump. Sun CC produces typedef
4041 rtx and the name of *rtx is zero...
4043 Mon Feb 18 21:16:25 1991 John Gilmore (gnu at cygint.cygnus.com)
4045 Roll in changes from final AMD 29000 port (Tiemann).
4047 tconfig/am29k: Add COFF_ENCAPSULATE and TARGET=TARGET_AM29K
4048 for ../include/a.out.encap.h. This might not work now that BFD
4049 is separately compiled. Instead, BFD support for encap will have
4050 to translate machine type 29k into the right COFF_MAGIC.
4052 * infcmd.c: Remove references to inferior_pid that aren't used
4053 in actual ptrace calls; use target_has_execution, etc.
4054 (have_inferior_p): Remove function.
4055 (program_info): Print target info rather than "process number";
4056 avoid gratuitous messages unless from_tty.
4057 (run_stack_dummy, finish_command): Set proceed_to_finish.
4058 infrun.c: Remove inferior_pid refs. Decl & init proceed_to_finish.
4059 main.c: Lint. Lose have_inferior_p().
4060 inferior.h (have_inferior_p): Remove, lint.
4061 (proceed_to_finish): Add flag to ask that all regs be saved
4062 by normal_stop, for the few commands that need it, speeding up
4063 serial I/O. Add comments to stop_registers.
4065 * remote-eb.c: Remove newline from breakpoint message we grep
4066 for. Never time out when running the user program.
4070 Wed Feb 13 15:34:40 1991 John Gilmore (gnu at cygint.cygnus.com)
4072 Roll in changes from vxgdb-5.0.1:
4074 * dbxread.c (read_dbx_symtab): If we encounter a "FORTRAN COMMON"
4075 symbol in its raw form, we are processing an unlinked ".o" file.
4076 See if the target environment has assigned it an address, using
4077 target_lookup_symbol (VxWorks does), and enter it into the symtab
4080 * tm-vxworks.h (FRAME_CHAIN, FRAME_CHAIN_VALID): Override usual
4081 68k versions for a simpler version that assumes zero FP at bottom.
4082 Fixes bug of truncated stack reports.
4084 * target.h (target_lookup_symbol): Define this routine's args
4085 and result, finally.
4087 * target.c (nosymbol): Default routine for target_lookup_symbol.
4088 (target_default): Default lookup_symbol and call_function too.
4089 (files_info): Only print has_all_memory warning if a non-dummy
4092 * remote-vx.c (vx_read_register, vx_convert_to_virtual,
4093 vx_convert_from_virtual): If target does not have floating point,
4094 zero register "values", and avoid doing cross-net conversions.
4095 (vx_lookup_symbol): Rename net_lookup_symbol, add to vectors.
4096 (vx_open): Rearrange code that attaches to target and reads
4097 symbols for all loaded modules, to work if some of the modules
4098 are not accessible. Add symbol_stub() and add_symbol_stub()
4099 as callbacks from catch_errors(). Allow connect attempt to be
4100 interrupted painlessly with ^C (FIXME, there are still some bugs
4101 if the interrupt happens during symbol reading.). Print
4102 final message with puts_filtered, since symbol messages are
4107 * main.c (catch_errors): Only print errstring if non-null.
4108 (command_loop): Avoid an ioctl per command to test ISATTY.
4110 * remote-vx.c (net_load): make static; avoid sophomoric msg.
4111 (vx_xfer_memory): Return correct result!
4112 (vx_files_info): Indicate whether target has float or not.
4113 (vx_lookup_symbol): Complain, not error, if target gone.
4114 (vx_open): Print "Connected" msg before disabling immediate-quit.
4115 [FIXME: lookup_symbol and vx_open changes need testing.]
4117 target.c, remote-eb.c, inftarg.c, am29k-opcode.h, target.h,
4118 tm-29k.h, tmm-vxworks68.h, symfile.c, gdb-int.texinfo: Add
4119 contributor lines and update copyrights to 1991.
4121 Changes from an attempted H-PUX host port:
4123 * infptrace.c (PT_ATTACH, PT_DETACH): Handle HP/UX, which
4124 defines PT_ATTACH and PT_DETACH but not PT_KILL.
4125 * remote-eb.c (eb_open): Misplaced endif kills sysv H/PUX.
4126 * remote-vx.c: include <sys/time.h> for HPUX.
4127 * hp300hpux-xdep.c (fetch_core_registers): Rewrite old
4128 "core_file_command" routine to BFD regime. May not work yet.
4130 Attempted port of "gdb-3.4 Van Jacobson xgdb" to modern gdb.
4132 * xgdb.c: Replace X10 version with some VJ version.
4133 (FIXME: Its copyright assignment is not on record.)
4134 * xgdb.c: Update include files to X11R4 (Xaw crud).
4135 (xgdb_display_source, create_text_widget): fix call to
4136 get_filename_and_charpos. Rewack source window stuff for X11R4
4137 (gleaned from include files, and "nm's" of binary libraries, since
4138 I had no doc available).
4139 (append_selection, append_selection_word): Disable with FIXME
4140 since R4 changed interface here.
4141 (create_buttons): Add back the old set of buttons.
4142 (xgdb_create_window): Fix call to XtInitialize (&argc not argc).
4144 * Makefile.dist (xgdb, xgdb-init.c): Update for X11R4 on Suns.
4145 Roll VERSION to 3.94 (not yet final though).
4147 Sat Feb 9 09:46:25 1991 John Gilmore (gnu at cygint.cygnus.com)
4149 * obstack.h (obstack_ptr_grow, obstack_ptr_grow_fast,
4150 obstack_int_grow, obstack_int_grow_fast): Eliminate
4151 cast on left of assignment, which gives MIPS cc fits and is
4154 * sparc-pinsn.c (print_insn): Eliminate 'set' test, subsumed by
4155 F_ALIAS. Use printf, not fprintf, when not passing a file
4157 (compare_opcodes): Check that identical instructions have
4158 identical opcodes, complain otherwise.
4160 * sparc-opcode.h (st %fsr): Fix opcode "lose" mask. This
4161 was reported by Roland McGrath.
4162 (unimp): Only match if exactly zero instruction. (Roland)
4163 (branches and traps): Generate all variations of these
4164 instructions with macros, based on a single call that defines
4165 each condition name and its binary representation.
4166 (set): Turn on alias bit, to avoid test in sparc-pinsn.c.
4168 * valprint.c (val_print_fields): Take, and use, format parameter.
4169 This means that "p/x struct" again prints the elements in the
4170 desired format. Changed callers.
4172 * stack.c (frame_info): Use filtered output, and indicate wrap
4173 points. Remove kludgy formatting designed to avoid line wrap.
4175 * utils.c (wrap_here): If the line is already full (because
4176 we had printed a long indent or long wrapped string), do an
4177 immediate newline-and-indent.
4179 * m68k-pinsn.c (print_insn_arg): Bugfix from
4180 ntmtv!thompson@ames.arc.nasa.gov (Mike Thompson): 'bkpt #0'
4181 instruction is incorrectly disassembled as bkpt #8.
4183 * dbxread.c (end_psymtab): Bugfix from Peter Schauer
4184 <pesrem@regent.e-technik.tu-muenchen.de>: If you want to set a
4185 breakpoint in a *.y file gdb will say Reading in symbols for *.y...
4186 and then will dump core (sometimes). I traced it back to an
4187 uninitialized symfile_name in psymtab_to_symtab.
4188 (const_vol_complaint): Add quotes to message.
4189 (define_symbol): Only believe line number if gcc_compiled.
4190 Avoid allocating symbol if we will not return it.
4192 Add target strata support so that newly established targets go
4193 into their right place in the target stack (e.g. a new exec file
4194 doesn't wipe out the ability to access the running process).
4196 * target.h, core.c, exec.c, inftarg.c, remote-eb.c,
4197 remote-nindy.c, remote-vx.c, remote.c, target.c: Add to_stratum
4198 and initialize it properly in all the targets.
4200 * target.h: Document strata. Change return type of push_target.
4202 * target.c (nomemory): new function for dummy memory access.
4203 (tcomplain): Rename complain, now also used in symfile.c.
4204 (push_target): Push targets within strata. New return value shows
4205 whether new target is on top of stack or not. Always keep dummy
4207 (target_files_info): Ignore dummy target.
4209 * core.c (core_open): Warn user, and skip accessing file, if the
4210 core target is not the topmost target in the stack.
4211 * remote-nindy.c (nindy_create_inferior): Avoid unpush_target, now
4214 * remote-vx.c: Remove vx_prepare_to_store from vxworks memory
4215 target_ops, it doesn't belong there since we have no regs there.
4216 Change name of target from machine => memory to clarify.
4218 Thu Feb 7 16:32:09 1991 John Gilmore (gnu at spiff.cygnus.com)
4220 * Freeze version 3.93 for release.
4222 * Makefile.dist: Handle vx-share and nindy-share subdirs
4223 properly when building gdb.tar.Z.
4225 * symtab.c: lint; add no_symtab_msg to consolidate the messages
4226 printed in various places, so I could change just one copy.
4228 * dbxread.c, coffread.c: Change references to bfd->iostream
4229 to cast to FILE *, now that BFD avoids needing types defined
4230 in other header files.
4232 Tue Feb 5 21:39:35 1991 John Gilmore (gnu at cygint.cygnus.com)
4234 * command.c, dbxread.c, expprint.c, infcmd.c, infptrace.c,
4235 infrun.c, printcmd.c, remote-nindy.c, source.c, sparc-tdep.c,
4236 sparc-xdep.c, symfile.h, symmisc.c, utils.c, valprint.c: Lint
4237 (actually gcc -Wall).
4239 * dbxread.c: Remove first_global_sym, last_global_sym, since
4240 they are never referenced.
4242 * defs.h (baud_rate): Declare.
4243 main.c: Define it, and add the -b option to set it.
4245 * gdb-int.texinfo: Add text on how to define a new host or target
4246 architecture, prompted by Per Bothner's questions about MIPS
4249 * gdb.texinfo: Document "complaints". Change doc of -q since
4250 gdb no longer prints the copyright and blurb if you specify a file
4251 name to be debugged (just like Emacs). Add doc for Nindy-specific
4252 command line flags for specifying target serial port and such.
4253 Update copyright to 1991.
4255 * gdbcore.h: Remove a large mass of now-useless crud, since BFD
4256 has taken over for us the job of ripping up executable files. The
4257 crud caused Per Bothner's port to not compile.
4259 * infrun.c (normal_stop): Avoid printing "Program exited
4260 normally" if we are in batch mode. This allows a GDB which
4261 executes a program on a target system, to behave like a Unix
4262 command (input from stdin, output to stdout, no extraneous
4265 * main.c (main): Allow additional machine-dependent command line
4266 options to be specified with the ADDITIONAL_OPTIONS,
4267 ADDITIONAL_OPTION_CASES, ADDITIONAL_OPTION_HELP, and
4268 ADDITIONAL_OPTION_HANDLER macros. Also allow machine-dependent
4269 processing to occur just before the main loop with
4270 BEFORE_MAIN_LOOP_HOOK.
4271 (main): If a "core file" argument is specified, and it is not a
4272 core file, try it as a process ID to attach.
4273 (symbol_completion_function): Attempt to cope with
4274 "show screen-" TAB, not very successfully. This needs more work,
4276 (batch_file): New function, returns whether we are reading
4277 commands from an interactive tty on stdin, or from somewhere else.
4278 Called by normal_stop since it doesn't get from_tty passed down
4279 to it like many commands do.
4281 * remote-nindy.c: Handle command line options for nindy
4283 (nindy_before_main_loop): Prompt user for tty name if they
4284 don't specify it before getting to the interactive command loop.
4286 * tm-i960.c: Add ADDITIONAL_OPTIONS, etc, to handle -O, -brk,
4287 and -r command line options. Also add hook before main loop
4288 to make it easy to specify a tty.
4290 * TODO: More things to do, one done.
4292 Mon Feb 4 23:57:39 1991 John Gilmore and Mike Tiemann (at cygint.cygnus.com)
4294 * dbxread.c: Make complaint() calls pass pointer, not struct.
4295 Add complaints about badly formatted C++ type information
4296 (const/volatile indicator, and parse errors resulting in
4297 error_type). Fix C++ virtual member fn comment.
4298 (read_struct_type): Avoid bumping pointer if we got a parse
4299 error; this prevents our walking beyond the end of a string.
4300 Terminate loop on null char as well as semicolon.
4301 (process_one_symbol): Fix the LBRAC fix so that it uses the
4302 last previous SLINE, FUN, or SO record's PC address. C++ debug
4303 symbols did not have SLINE records in a useful order compared
4304 to the LBRAC records.
4305 (define_symbol): Handle "catch" records.
4307 * symtab.c (check_stub_type): Added new complain
4308 `stub_noname_complain' and added a consistency check to
4309 keep the debugger from crashing when finishing from an
4310 exception frame. A real fix will be needed later.
4312 Sat Feb 2 10:43:05 1991 John Gilmore (gnu at cygint.cygnus.com)
4314 * infcmd.c (attach_command): Make global.
4316 * Makefile.dist (REMOTE_OBS): Make these compile by default,
4317 but make them easy to comment out. Perhaps later they should
4318 be enabled by what CPU you configure for? FIXME.
4319 (VERSION): Roll to 3.93.
4320 (pinsn.o): Remove rule for obsolete file.
4321 (dbxread.o,coffread.o,mipsread.o): Use ${srcdir} explicitly.
4323 Run down a problem that manifested by printing the wrong function
4324 name in stack traces of read_ofile_symtab. Turned out that the
4325 problem was the SunOS 4.1.1 (and previous) C compiler outputs
4326 the LBRAC symbol with an address in the *data* segment, which
4327 blew our binary search through the blocks.
4329 * dbxread.c: Use the complain() facility consistently to bitch
4330 about problems in the symbol file we are reading.
4331 (finish_block): Add code to check the nesting of the blocks;
4332 complain and Procrust them to fit if wrong.
4333 (make_blockvector): Check the order of the blocks, complain
4334 [but don't cope] if wrong.
4335 (process_one_symbol): ifndef SUN_FIXED_LBRAC_BUG, check LBRAC
4336 symbols to be sure their PC value is greater than the last SLINE
4337 (line number) symbol we've seen, complaining and adopting the
4338 SLINE PC value if wrong.
4340 * symfile.h (struct complaint, complaint_root, complain,
4341 clear_complaints): Add.
4342 * symfile.c (complain, complaint_root, clear_complaints): Add
4343 facility to deal with non-fatal complaints and to regularize their
4345 (symbol_file_add): Clear complaint counters to allow new complaints.
4346 (initialize_symfile): Add 'set complaints' and 'show complaints'.
4348 * dbxread.c (dbx_symfile_read): Remember the address and size
4349 of the string table for the main symbol file, so we won't read it
4351 (dbx_psymtab_to_symtab): Fix the check for main symbol file,
4352 to avoid reading the string table yet again. Lint.
4353 (throughout): Improve filtered output, including word wrap.
4354 (read_range_type): Improve Bothner's fix to handle other types too.
4356 * utils.c: Improve line wrap implementation. Handle unlimited
4357 width by making chars_per_line unsigned.
4358 (puts_filtered): New, easy, function.
4360 * defs.h (puts_filtered): add.
4362 * mipsread.c (compare_symbols, sort_symtab): Remove these fns,
4363 call the identical sort_symtab_syms() in symfile.c instead.
4365 * expread.y: Suggest the `file' command rather than `symbol-file'.
4367 * command.h (enum var_types): Add zinteger for seroable
4369 * command.c (do_setshow_command): Handle var_zinteger. Restructure
4370 nested if's into a switch.
4372 * breakpoint.c (bpstat_print): If bpstat "print" flag is not set,
4373 we did not stop because of a breakpoint (it must have been for
4374 some other reason, like a "stepi"), so don't print anything.
4376 * symtab.c: Include <sys/types.h> all the time. Now that BFD
4377 doesn't include <sys/types.h>, old SunOS's require it for
4380 Sat Feb 2 10:39:15 1991 Per Bothner (bothner@cs.wisc.edu)
4382 A test port of gdb-3.92.6 to the Sony NEWS.
4385 Don't normally link in remote- or vx stuff.
4386 Some of it doesn't compile, and it wastes space for 99% of the users.
4387 Remove reference to no-longer-used HAVE_VPRINTF.
4388 Fixed BFD_DEP typo to BFD_DIR.
4390 Fix cast in arg to bfd_h_getlong.
4391 Make char *prefix be const.
4392 Fix how certain range types are mapped into builtin unsigned int types.
4394 Remove 2 #includes. They cause errors (on Sony, at least),
4395 and aren't needed (they wern't in earlier versions).
4397 print_address_symbolic should never demangle labels
4398 (since it prints *assembler-level* labels).
4400 [This was superseded by the change to printcmd below.]
4403 Add some "volatile" return types to avoid warnings.
4404 If MISSING_VPRINTF add vprintf function and not just macro
4405 (since vprintf is used in printcmd.c).
4407 Unless __GNUC__, use obstack_grow instead of obstack_ptr_grow.
4408 (The latter isn't grokked by some PCC-based compilers.)
4410 [This change is in abeyance, we prefer to fix obstack_ptr_grow.]
4412 Make chunk size of dont_print_obstack 32*4 instead of default 4096.
4413 * nindy-share/coffstrip.c
4414 Added some forward declarations (otherwise, gcc complains
4415 about implicit extern redefined as static).
4417 Sun Jan 20 02:38:19 1991 John Gilmore (gnu at cygint.cygnus.com)
4419 Changes inspired by Per Bothner:
4420 * printcmd.c (print_address_symbolic): Take additional parameter
4421 specifying whether to demangle.
4422 (print_address): Pass in asm_demangle to control demangling.
4423 (print_address_demangle): New fn, takes explicit arg to control
4425 * utils.c: Add new vars demangle and asm_demangle, and let them
4427 (fputs_demangled): If !demangle, just print the argument.
4428 (fprint_symbol): If !demangle, just print raw symbol.
4429 * valprint.c (val_print): Call print_address_demangle rather than
4430 print_address, to cause demangling to depend on the global
4431 rather than assembler-level demangling setting.
4432 * WHATS.NEW, gdb.texinfo: Document.
4434 * main.c (show_command): Show all settings if no arg.
4435 (initialize_main): Make "info set" the same as naked "show".
4436 * command.c (cmd_show_list): Handle prefix commands in the
4437 list, and print the name of the setting as well as its English
4438 description and value.
4440 Allow gdb functions to specify where a line should wrap if it
4441 exceeds the size of a terminal line. Use it to make the output
4443 * utils.c (set_screen_width_command): New fn, mallocs a buffer
4444 of the right size when screen width changes.
4445 (set_screensize_command, screensize_info): Remove #if 0'd fns.
4446 (wrap_here): New fn, indicates a point in the output where we
4447 should wrap the line rather than just letting it overflow at a
4449 (fputs_filtered): Implement wrapping.
4450 (n_spaces): New fn, returns a pointer to N spaces.
4451 (print_spaces_filtered): Use n_spaces.
4452 * defs.h (n_spaces): Declare.
4453 * stack.c (print_frame_info): Wrap with 4-space indent after
4454 fn name and before filename and line number.
4455 * printcmd.c (print_frame_args): Wrap with 4-space indent
4456 before each argument name is printed.
4457 * valprint.c (value_print): Wrap with no indentation before
4459 (val_print_fields): Wrap with indentation relative to nesting
4460 level before each field name.
4461 (val_print): Wrap with nesting indentation before array elements.
4462 * command.c (do_setshow_command): Avoid extra newlines,
4463 wrap with 4-space indent around values printed, end with period.
4464 * WHATS.NEW, gdb.texinfo, gdb-int.texinfo: Document.
4466 * breakpoint.c (breakpoint_1): Implement addressprint for
4467 "info breakpoints" display. Change file name and line number
4468 format to " at file:nnn" rather than " (file line nnn)".
4469 * gdb.texinfo: Document.
4472 Fri Jan 18 07:21:25 1991 John Gilmore (gnu at cygint.cygnus.com)
4474 Frozen for gdb-3.92.6 release.
4476 README, WHATS.NEW: Update for 3.92.6 release.
4478 tconfig/{altos, i386v, i386v32, m88k, umax}: Eliminate
4479 coffread.o from configs since it is now built by default.
4480 tconfig/{3b1, altosgas, arm, convex, hp300bsd, hp300hpux,
4481 i386v-g, i386v32-g, isi, merlin, news, news1000, np1, pn,
4482 pyramid, symmetry, vax, vxworks68}: Eliminate dbxread.o
4483 from configs since it is now built by default.
4485 Makefile.dist: Update for release 3.92.6. Handle files that
4486 have been moved to ../include, ../getopt, or ../bfd. Add
4487 saber.suppress and tests directory. Add config.status to
4488 the release (it will say "none").
4490 coredep.c: Minor formatting fixes.
4492 These changes were made in early December but only checked in now:
4493 * nindy-share/Onindy.c, nindy-share/coffstrip.c,
4494 nindy-share/nindy.c: lint
4495 * nindy-share/nindy.c (ninStopWhy): Don't byteswap the
4496 register values coming back from the target; we store values
4497 in target byte order everywhere.
4499 Wed Jan 16 19:01:37 1991 John Gilmore (gnu at cygint.cygnus.com)
4501 * am29k-opcode.h, am29k-pinsn.c: Add 29050 opcodes.
4503 * valprint.c (cplus_val_print, val_print_fields): New functions,
4504 which print C++ objects. They conspire to avoid printing a
4505 virtual base class more than once, following all the twists and
4506 turns of C++ virtual base rules.
4507 (val_print): Call the above rather than do it by hand.
4509 * symfile.c (symbol_file_add): Only reset symfile_mtime for main
4510 symbol file, not for added files like shared libs. This really
4511 needs to be generalized to a timestamp per file.
4513 * core.c (cleanup_core): Avoid coredump if no core file.
4515 * config.gdb: Accept -host or -target in place of +host or
4518 * coffread.c (find_linenos): Avoid desupported BFD interface
4519 to line numbers. We still read them manually rather than using
4520 BFD's "generic" features.
4522 * gdbrc.tex, threecol.tex: Add GDB reference card and its
4524 Makefile.dist: Add refcard to OTHERS list for creating tar files.
4526 * Makefile.dist: Eliminate use of $< in explicit targets.
4528 * readline/Makefile: Use $< rather than $*.c, which does not
4529 include the VPATH in GNU Make.
4531 * tconfig/i960-bout, tconfig/i960-coff: These are identical
4532 copies of tconfig/i960, added for global configuration
4533 compatability. All i960 versions can read both coff and b.out.
4535 * tm-88k.h: Fix multiline macro that lacked \'s. Remove
4536 COFF_FORMAT and COFF_CHECK_X_ZEROES since these are now handled
4539 * TODO: Think of more things to do.
4541 Wed Jan 2 19:09:29 1991 John Gilmore (gnu at spiff.cygnus.com)
4543 tconfig/{am29k,i960,sun2*,sun3*,sun4*}: Eliminate config
4544 of sdb versus dbx debug symbols. Add kludge for 68881 80-bit to
4545 64-bit float conversion.
4547 tconfig/sun4, tconfig/sun3, xconfig/sun4, xconfig/sun3: Make
4548 equivalent to sun?os4 so global config works.
4550 Wed Jan 2 18:20:51 1991 John Gilmore (gnu at spiff.cygnus.com)
4552 Fix from Eberhard Mattes <mattes@azu.informatik.uni-stuttgart.de>
4554 * main.c: Only declare linesize once; declare pagesize not at
4555 all, since it is never used.
4556 (main): Clear newly allocated line before it is used.
4558 Fri Dec 28 00:13:42 1990 John Gilmore (gnu at cygint)
4560 Further stabilization for the Intel 960.
4562 * Makefile.dist: Parameterize the location of the "include"
4563 and "bfd" directories, as well as "getopt". Add symfile.c.
4564 Link in both dbxread and coffread. Fix up "make depend" to
4565 rewack the locations of include, bfd, and getopt in its output.
4567 * README: Document moving include files, improve some of
4570 * coffread.c: Move common code out to symfile.c. Change
4571 symbol_file_command style interface to use new *_symfile_init
4572 and *_symfile_read interface under BFD. Use BFD internal
4573 info to locate line table, symbols, etc.
4575 * core.c (core_fetch_registers): Rename to get_core_registers
4576 to avoid confusion with fetch_core_registers.
4577 (register_addr): Move to coredep.c, which is already machine
4578 dependent. This leaves core.c pretty clean of dependencies.
4580 * coredep.c (register_addr): Accept this routine from core.c.
4582 * dbxread.c: Move common code (with coffread.c, etc) into new
4583 symfile.c. Each psymtab now contains a pointer to the
4584 format-dependent function that knows how to read it in. Make
4586 (dbx_psymtab_to_symtab): Renamed from psymtab_to_symtab_2.
4587 (process_one_symbol): Add code to complain about a "compiler bug
4588 we muzzle here", if we actually see it.
4590 * eval.c (evaluate_subexp): Insert missing "break" statements
4591 in code that determines whether a variable is an lvalue in
4592 memory, register, or whatever. I detected this via a compiler
4593 bug in which it *almost* mashed out the whole switch statement.
4595 * gdb-int.texinfo: Add minor sections on configuring gdb for
4596 release, and about the README file.
4598 * infcmd.c (registers_info): Fix formatting somewhat. Still
4599 not as pretty as before, but it handles byte swapping.
4601 * remote-nindy.c: If data cache routines are interrupted while
4602 waiting for the remote end, be sure that any uninitialized cache
4603 blocks are on the free list, not on the valid list!
4605 * symfile.h: Flesh out this header file with all the various
4606 routines and variables that have been merged in from dbxread.c
4607 coffread.c, and symtab.c to symfile.c.
4609 * symfile.c: New file, containing code common to dbxread.c,
4610 coffread.c, and some code from symtab.c. All generic code for
4611 reading symbol files should be in here now.
4612 (unrecord_misc_function): Remove unused function.
4614 * symtab.h: Remove file-reading things to symfile.h.
4616 * symtab.c: Remove file-reading things to symfile.c.
4618 * tm-i960.h: Fix FRAME_CHAIN types; define PRINT_RANDOM_SIGNAL
4619 to decode i960 fault types.
4621 * target.h, remote.c, remote-eb.c, remote-vx.c, remote-nindy.c,
4622 target.c: Change type of the "resume" function from int to void,
4623 since its result was never used.
4625 Sat Dec 22 02:51:40 1990 John Gilmore (gnu at cygint)
4627 * main.c: Replace "stupid" with "caution"; you now "set caution
4630 * printcmd.c (print_scalar_formatted): Fix typo in 'g' format
4632 * infcmd.c (do_registers_info): Call val_print to deal with the
4633 byte order of the registers being printed. FIXME, this makes
4634 the formatting of the output uglier.
4636 * infcmd.c (wait_for_inferior): If PRINT_RANDOM_SIGNAL is
4637 defined, call it for signals the debugger doesn't itself use.
4638 The i960 uses this for more detailed fault information.
4640 * remote.c (remote_open): If arg is null, print help rather than
4643 * sparc-xdep.c (register_valid): Avoid declaring size, since
4644 various modules will think of various sizes depending on the
4645 architecture of their tm-file. FIXME, we need protection against
4646 actually entering one of those modules, which would clobber
4647 storage if not for the target architecture compiled into gdb.
4649 * stack.c (up_command, down_command): Always print the frame
4651 (up_silently_command, down_silently_command): New commands
4654 * i960-pinsn.c (reg), i960-tdep.c: Lint.
4656 * i960-tdep.c (i960_frame_chain_valid): Lookup_symbol now takes
4657 more parameters than it used to.
4659 * findvar.c (registers): Increase slop to 256 bytes, which should
4660 protect us against even most RISC machines with large register
4662 (locate_var_value): Move declaration inside related ifdef.
4664 * remote-nindy.c (): Use TIOCSETN rather than TIOCSETP
4665 throughout, to avoid throwing away buffered input from the board.
4666 (nindy_wait): Supply_register takes addr_of_value, not value.
4667 (i960_print_fault): Renamed from i80960_fault.
4668 (nindy_fetch_registers): Avoid have_regs stuff, just get them.
4669 (nindy_store_registers): Avoid regs_changed stuff, just stuff
4671 (nindy_create_inferior): Don't bother to write PC_REGNUM since
4672 we can set the PC in the call to proceed(). Unpush nindy_ops
4673 before pushing it on top, to avoid message to user. Eliminate
4674 commentary from Unix machines that just misleads here.
4675 (reset_command): Fix error message to suggest target command.
4677 Wed Dec 19 11:03:56 1990 John Gilmore (gnu at cygint)
4679 Release 3.92.5 as frozen.
4681 Stabilize the merged release...with help from lint, Saber C,
4684 Everywhere: Add include files needed to declare return types
4685 of functions called.
4687 * gdb.texinfo: Roland Pesch is documenting gdb, glory be!
4689 * breakpoint.h: Add undeclared breakpoint functions, and some
4690 functions for display handling since I couldn't think of a better
4693 * breakpoint.c (insert_breakpoints): Make code for disabling
4694 shared library bkpts more likely to work. It's used when we
4695 rerun a program and stop before the shared library has been
4697 (breakpoint_cond_eval, bpstat_stop_status): Pass arg as int,
4698 cast from pointer, so it squeezes through catch_errors.
4699 (bpstat_stop_status): Fix logic broken some time ago. We now
4700 always create a bpstat if the stop address matches a breakpoint,
4701 even if we don't stop there -- just like the old code used to do
4702 before I got my fingers into it (sigh).
4703 (breakpoint_1): Print "ignore count" after "stop only if"
4704 condition, since that's how it actually works.
4705 (mention): Handle watchpoints as well as breakpoints.
4706 (watch_command): use set_raw_breakpoint and mention to do most
4707 of the work (and initialize all the fields!). Only pass one
4708 arg to parse_c_expression, since that's all it takes.
4710 * command.c (not_just_help_class_command): Rename arg to args
4711 since we ignore "unused argument" warnings on vars named "args".
4712 inflow.c (child_terminal_info): ditto.
4713 infptrace.c (kill_inferior): ditto
4714 main.c (catch_errors, version_info, quit_command, pwd_command,
4715 source_command, dump_me_command, editing_info,
4716 set_history_size_command, set_history, show_history,
4718 stack.c (locals_info): ditto
4719 target.c (target_files_info): ditto
4720 valprint.c (set_input_radix, set_output_radix): ditto
4722 * core.c: Remove old variables for handling core and exec file
4723 sections (data_start, data_end, stack_start, stack_end,
4724 reg_stack_start, reg_stack_end, reg_stack_offset, text_start,
4725 text_end, exec_data_start, exec_data_end, text_offset,
4726 exec_data_offset, data_offset, stack_offset). They're
4727 superseded the more general build_section_table and
4729 (get_exec_file): Mention the `file' command.
4730 (read_memory_check): Rename to memory_error, and only call it
4731 in the case of an actual error.
4732 (read_memory, write_memory): call memory_error.
4733 (core_fetch_registers): Register section name is ".reg".
4735 coredep.c: Remove a bunch of crud now that all this file does
4736 is pull the registers out of a core file.
4737 (fetch_core_registers): Rewrite to actually work, I hope.
4739 dbxread.c: Use a.out.gnu.h, not system a.out, now.
4740 Replace index() with strchr(). Remove all the pre-BFD macro
4741 definitions for accessing the symbol file.
4742 (struct dbx_symfile_info): Encapsulate the information that
4743 dbx_symfile_init needs to pass to dbx_symfile_read in this
4746 (dbx_new_init, dbx_symfile_init, dbx_symfile_read,
4747 dbx_symfile_discard): Rearrange symbol file reading to divide
4748 the format-specific part from the format-independent part,
4749 leaving the format-independent part such as file name expansion
4750 and opening in symtab.c. This replaces
4751 partial_symbol_file_open and partial_symbol_file_read.
4752 Symbol_file_read, add_file, add_file_target_command,
4753 add_file_addr_command move to symtab.c. Pass an explicit
4754 "mainline" flag for when reading the main symbol table, rather
4755 than relying on the offset address to be zero or nonzero.
4757 (dbx_symfile_read): Don't allow void *'s to be printed as
4759 (SWAP_SYMBOL): Use bfd routines to byte-swap the symbols.
4760 (ADD_PSYMBOL_TO_LIST): Make the "function call rather than
4761 macro" debug version really work.
4762 (read_dbx_symtab): Remove unref'd parameter inclink.
4763 Avoid swapping N_SLINE symbols, for speed.
4764 Merge N_TEXT!N_EXT case with the other external symbol
4765 definitions' case. Add comments.
4766 (start_psymtab): Allocate the symfile name in the psymtab on
4767 the psymbol_obstack, rather than using the caller's storage.
4768 (end_psymtab): Only allocate a dependencies list if there are
4770 (psymtab_to_symtab_2): Use BFD when reopening file to read
4771 its symbols for real.
4772 (read_struct_type): Add FIXME comments where it needs work
4774 (read_huge_number): Add FIXME about overflows.
4775 (read_range_type): Add FIXME about comparing a long to 1<<32.
4777 * coffread.c: Minor changes to move things closer to the new
4778 regime with symtab.c and dbxread.c Major work is still needed
4781 * exec.c (exec_file_command): Remove old variables (see core.c
4783 (xfer_memory): If memory transfer is right at the end of a
4784 section, don't lose.
4786 * findvar.c (get_saved_register): If value is in a real
4787 register, LVAL is lval_register, not lval_memory.
4789 frame.h: Declare print_sel_frame and record_selected_frame.
4791 gdb-int.texinfo: New file, for GDB internals documentation.
4792 Very simple, unformatted doc of cleanups is there for now.
4794 gdbcore.h: Remove obsolete variables that described a.out
4795 section addresses and offsets. (See core.c above.)
4796 Declare fetch_core_registers and registers_fetched.
4798 getopt.c: Declare char *alloca(); even on SPARC.
4800 infcmd.c (run_command): Call target_kill rather than
4802 (step_command, next_command, stepi_command, nexti_command):
4803 Declare from_tty parameter even though we don't use it.
4804 (run_stack_dummy): argument BUFFER is a char array, not
4805 a pointer to REGISTER_TYPE.
4806 (finish_command): using_struct_return needed a value *,
4807 not a struct symbol *.
4809 * infptrace.c (child_xfer_memory): To avoid dependency on
4810 where sections are in memory, try PT_WRITE_D and if that fails,
4811 try PT_WRITE_I. Most Unixes don't care which you use.
4813 * infrun.c (step_resume_break_shadow): Change to array to
4814 match other breakpoint shadow storage.
4815 (clear_proceed_status): Pass address of bpstat to
4816 bpstat_clear, not the bpstat itself.
4817 (child_create_inferior): FIXME comment about if the child
4819 (start_inferior): Remove old function.
4820 (child_open): Use target_kill rather than kill_inferior.
4821 (wait_for_inferior): Ditto.
4822 (insert_step_breakpoint, remote_step_breakpoint): Use
4823 new step_resume_break_shadow.
4825 * inftarg.c (child_wait): If all child processes die,
4826 pretend that the one being waited for exited with signal 42.
4828 * main.c (command_line_input): When scanning for comments,
4829 don't coredump on unclosed quotes.
4830 (quit_command): Use target_kill rther than kill_inferior.
4831 (_initialize_main): Rename class_user from "user" to
4834 * printcmd.c (print_command_1): Initialize "fmt" if no format
4835 is specified by the user.
4836 (print_frame_args): Only add to args_printed if we are
4837 actually fetching args from the stack (avoiding undefined
4839 (_initialize_printcmd): Remove bogus \{ from string.
4841 * remote-eb.c (eb_open): Avoid coredump on no argument.
4843 * remote-nindy.c: Bring out of Intel environment into new
4844 target environment. Remove all conditional compilation on
4845 I80960. Massive hacking throughout.
4846 (nindy_xfer_inferior_memory): New routine stolen from
4848 (nindy_create_inferior): New routine pieced together, probably
4849 not quite working yet.
4850 (nindy_ops): New target_ops struct for nindy.
4852 * remote-vx.c: Use write_memory rather than target_write_memory
4853 to get error checking.
4854 (vx_add_file_command, vx_open): Use symbol_file_add rather than
4856 (vx_create_inferior): Use target_terminal_ours...
4858 * signame.c (_initialize_signame): Always initialize, since
4859 we need the table for things other than psignal.
4861 * solib.c (solib_add): Use symbol_file_add, not add_file.
4862 (solib_address): Return boolean result rather than struct
4863 pointer which nobody else knows the type of.
4865 * sparc-tdep.c, valops.c: Use write_memory rather than
4866 target_write_memory, to get error checking.
4868 * stack.c (locals_info, catch_info, args_info,
4869 get_selected_block, frame_command, up_command): Use
4870 target_has_stack, rather than have_inferior_p or
4873 * sun3-xdep.c (fetch_core_registers): Rewrite for new BFD regime.
4875 * symfile.h: New file, defining the interface between the
4876 generic and object-file-specific symbol reading code.
4878 * symtab.c: Move generic symbol-reading interface to symtab.c,
4879 from dbxread.c, coffread.c, mipsread.c, etc. Add symtab_fns
4880 table to map BFD targets to symbol-reading modules in GDB.
4881 Change index to strchr.
4882 (lookup_struct_elt_type): Use error() rather than hand-made
4883 simulations thereof.
4884 (lookup_partial_symbol): Speedup slightly when length == 0.
4885 (symbol_file_add): New function.
4886 (symbol_file_command): Call it.
4887 (symfile_open, symfile_init): New function.
4888 (add_file_target_command, add_file_addr_command): moved from
4891 * target.c (target_command): use target_kill.
4893 * target.h (target_files_info): Don't declare, never called
4896 * tm-sun2.h, tm-sun3.h (STACK_END_ADDR): Use system include
4897 files to determine stack end address.
4899 * valarith.c (value_x_binop, value_x_unop): Change error message
4900 to be more useful. Pass proper argument to value_struct_elt.
4902 * valops.c (value_assign): FIXME comment that long long
4903 bitfields will break here.
4905 * Makefile.dist: Add symfile.h, remote-nindy.c, remote-eb.c.
4906 Update `make saber_gdb' to work better.
4908 * TODO: A woman's work is never done.
4910 * cplus-dem.c, environ.c, inferior.h, infrun.c, inftarg.c,
4911 main.c, obstack.c, printcmd.c, remote-eb.c, remote-nindy.c,
4912 remote-vx.c, remote.c, solib.c, source.c, sparc-pinsn.c,
4913 sparc-tdep.c, sparc-xdep.c, symmisc.c, symtab.c, symtab.h
4914 target.c, terminal.h, tm-sparc.h, tm-sunos.h, utils.c,
4915 valops.c, valprint.c, exec.c: Lint.
4918 Wed Dec 12 23:44:15 1990 John Gilmore (gnu at cygnus.com)
4920 Continuing Intel 960 port merge of GDB.
4922 * Makefile.dist: Merge i960 "nindy-share" files. Rename
4923 malloc.h to gmalloc.h to avoid name conflicts in /usr/include.
4924 Don't ship gdb.dvi in tar file. Link gdb with init.o, not init.c.
4925 Wack over "make depend" so it handles files in subdirectories
4926 vx-share, nindy-share, bfd, and in the current directory.
4928 * blockframe.c (get_prev_frame_info): Remove fatal error
4929 if stack not defined.
4931 * core.c (core_open, core_detach): New functions that handle
4932 the old "core-file" command as "target core" and "detach" instead.
4933 (core_file_command): Call them.
4934 (core_xfer_memory): Use common routine xfer_memory.
4936 * dbxread.c: Include a.out.gnu.h, not system a.out.h.
4937 dbxread now uses bfd for everything but symbol reading itself.
4938 BFD internals are used to drag out the relevant file offsets.
4939 (partial_symbol_file_open): Change args all around for BFD.
4941 * symtab.c: Rename "value" to "val" everywhere, so we can
4943 (symbol_file_command): New command, moved from dbxread.c
4944 and coffread.c. It uses BFD to read the file, then vectors
4945 based on its type, to dbx or coff symbol readers.
4946 * symtab.h: Extern a few vars for symbol_file_command.
4948 * target.h: Breakpoint takes a char * save area, not a char **.
4950 * valprint.c (val_print): When unpacking bitfields, offset
4951 the address in gdb of the value, if it is declared with a shorter
4952 type. Remove the last "runtime kludge test" of host byte order.
4954 * utils.c: Remove old my_bfd_read routine.
4956 * stack.c (frame_info): Use target_has_stack. Print program counter
4957 register's actual name rather than "pc", since it's called the
4958 "ip" (instruction pointer) on the i960 (sigh).
4960 * target.c (target_command): Add command for selecting a target
4961 type and calling its open routine. This is used for initiating
4962 communication with a particular target, in a generic way.
4964 * tm-i960.h: Update for modern gdb. Remove semicolons from
4965 various macros. Handle reading struct return convention, and
4966 error-out attempts to return structs with the "return" command.
4967 Be sure gdb doesn't think we know how to call functions in the
4970 * i960-tdep.c: Rename FRAME_CHAIN_VALID and FRAME_FIND_SAVED_REGS
4971 to i960_xxx in lower case.
4972 (arg_address): Circumvent errors due to LOC_ARG_BLOCK
4973 not being defined yet.
4975 * remote.c (remote_open): Call start_remote to initialize
4976 wait_for_inferior during open.
4977 (remote_xfer_inferior_memory): Return length written rather
4980 * remote-vx.c (target_command -> vx_open): Use new generic
4982 * remote-eb.c, inftarg.c, exec.c: ditto.
4984 * infrun.c: Fix comments.
4985 (attach_program -> child_open): Use new generic target command.
4986 (wait_for_inferior): Clear saved register values before target_wait,
4987 so target_wait can set some of them if convenient.
4989 * infptrace.c (fetch_inferior_registers, store_inferior_registers):
4990 Return success indicator, not void.
4991 (child_xfer_memory): Avoid fetching initial word if we'll
4992 overwrite it anyway.
4994 * infcmd.c (attach_command): Use new generic target open routine.
4995 (_initialize_infcmd): Update doc on attach and detach commands.
4996 (do_registers_info): Merge in a byte-order problem as a FIXME
4999 * findvar.c (find_saved_register): Avoid problem in current frame.
5000 (read_relative_register): Ditto.
5001 (write_register): Convert byte order on the way out.
5003 * exec.c (file_command): Add.
5004 (add_to_section_table, exec_command): Use new bfd_map_over_sections.
5005 (xfer_memory): Common function between core_xfer_memory and
5007 (exec_xfer_memory): Use it.
5009 * pn-opcode.h: Document that a "PN" is a Gould PowerNode.
5011 * breakpoint.c, breakpoint.h, symtab.h, value.h, frame.h, utils.c,
5012 valops.c, stack.c, target.c, sparc-xdep.c, source.c, printcmd.c,
5013 infcmd.c, i960-pinsn.c, eval.c, defs.h: lint and gcc -Wall.
5015 Sun Dec 2 16:45:06 1990 John Gilmore (gnu at cygnus.com)
5017 Merge Intel 960 port of gdb, continuing...
5019 * dbxread.c (partial_symbol_file_open, partial_symbol_file_read,
5020 symbol_file_command): Pass from_tty arg to hush 'em up.
5022 * coffread.c (symbol_file_command): Avoid output if from_tty != 1.
5023 Add magic numbers for 960 COFF format.
5025 Fri Nov 30 09:18:20 1990 John Gilmore (gnu at cygnus.com)
5027 Merge Intel 960 port of gdb, from Intel "1.2" release.
5029 CHANGE_LOG entries from their port, which was based on
5032 Thu Sep 6 11:02:22 PDT 1990
5033 Remove temp file if download is interrupted.
5035 Wed Aug 1 09:08:33 PDT 1990
5036 Now uses binary protocol to talk to NINDY.
5037 Old hex protocol (NINDY 2.13 and older) supported with -O switch.
5038 Times out after 5 seconds when trying to talk to NINDY.
5040 Tue May 29 12:54:49 PDT 1990
5041 Added variable baud rate (-b switch).
5042 Source code reorganization.
5044 Thu Apr 26 11:09:55 PDT 1990
5045 More cleanup of batch mode; specifically, execute "-s", "-e", and
5046 "-se" switches as soon as they are encountered on the invocation line.
5048 Fri Apr 20 13:47:15 PDT 1990
5051 Thu Apr 19 09:54:28 PDT 1990
5052 Add 'reset' command.
5054 Wed Apr 18 09:48:07 PDT 1990
5055 After opening remote tty, wait for 1 second to go by without input
5056 from it before trying to talk to NINDY (fixes problems with the
5057 Heurikon HK80/V960E).
5059 Mon Apr 4 16:33:05 PDT 1990
5060 Some output was not being suppressed in 'batch' mode.
5062 Thu Mar 22 15:31:11 PST 1990
5063 Ask user if old symbol table should be deleted when new file is
5066 Allow user to run a program downloaded before gdb960 was brought up.
5068 Correct "exec-file" help message for i80960 context.
5070 Correct bug in calculating user space address: could occasionally
5071 corrupt user program.
5073 Make sure to zero low-order bits in rip's because of bug in 960CA
5074 A-step part: could cause operation faults when "next"ing across
5077 Correct bug that made it impossible to get source line numbers for
5078 code loaded at addresses higher than 0x7fffffff.
5080 Wed Jan 10 12:43:22 PST 1990
5081 Open remote tty for exclusive use.
5083 Fri Jan 5 12:14:42 PST 1990
5084 Correct disassembly (CA manual was right after all):
5085 opcode for sysctl is 0x659
5087 Mon Oct 23 12:03:04 PDT 1989
5088 Use G960BASE and G960BIN environment variables to find 'sx' utility.
5090 Mon Oct 16 14:15:09 PDT 1989
5091 "sfr0"-"sfr31" should have been named "sf0"-"sf31"
5093 Mon Oct 2 15:56:31 PDT 1989
5095 Added 960CA disassembly support.
5097 To simplify maintenance:
5098 - eliminated use of symblic links on pinsn.c: use i960-pinsn.c
5100 - eliminated opcode.h: incorporates tables into i960-pinsn.c
5101 - moved 960-specific routines from i960-pinsn.c to i960-md.c
5102 - made disassembly interface identical to that in gdmp960.
5106 Wed Nov 28 21:32:48 1990 John Gilmore (gnu at cygint)
5108 * target.h: Allow targets to stack. Add target_has_memory,
5109 _registers, etc. Restructure memory access and "info files"
5110 to walk the target stack.
5111 * exec.c, core.c, inftarg.c, remote.c, remote-vx.c, remote-eb.c,
5112 target.c: Change tables to match target.h.
5113 * inflow.c (child_mourn_inferior): pop child_ops.
5114 (generic_mourn_inferior): Use new has_stack flag.
5115 * infptrace.c (child_xfer_memory): New memory regime.
5116 * inftarg.c (child_files_info): New "info files" regime.
5117 * remote-eb.c: New memory regime, new info files.
5118 * remote-vx.c: New memory regime, new info files. Now use
5119 separate targets for VxWorks attachment to machine, and
5120 actually running a process under VxWorks, since one has
5121 stack & execution & regs and the other doesn't.
5122 * remote.c: New memory regime, new info files.
5123 * sparc-xdep.c (fetch_core-registers): New memory regime.
5124 * target.c: New routines and support for stacked targets,
5125 new memory regime, new info files regime.
5128 Generalize section handling for an arbitrary number of sections,
5129 including use of the new BFD (binary file) library.
5130 * gdbcore.h: Add struct section_table.
5131 * exec.c (build_section_table): Iterate all sections and
5132 record what gdb needs to know about them.
5133 (exec_command): Use it.
5134 (exec_xfer_memory): Use the table.
5135 (exec_files_info): Print the table.
5136 * core.c (core_file_command, core_xfer_memory, core_files_info):
5138 * source.c (find_source_lines): Use bfd_get_mtime.
5139 * dbxread.c: Quick changes to make it compile with new BFD.
5140 * utils.c (error): Avoid using bfd_error in generic routines.
5142 * core.c (core_fetch_registers): Get from the ".regs" section of
5144 * sparc-xdep.c (fetch_core_registers): Use the .regs info.
5146 * inferior.h (attach_flag): Export.
5147 * infcmd.c (run_command): use new target_create_inferior.
5148 * infrun.c (child_create_inferior): Don't return result.
5149 * Makefile.dist (VERSION): 3.91.4.
5151 Fri Nov 23 28:15:38 1990 John Gilmore (gnu at cygint)
5153 * breakpoint.c (bpstat_num): Handle breakpoints which have
5154 since been deleted, such as temporary breakpoints.
5155 infcmd.c (program_info): ditto.
5157 * core.c (core_file_command): Display the frame where the core
5162 * remote-vx.c (target_command): Merge in target command from
5163 targ-vx.c. A few other cleanups.
5165 * TODO, Projects: Lots more stuff to do...
5167 Fri Nov 23 18:15:38 1990 John Gilmore (gnu at cygint)
5169 Massive changes to wall off the remote-debugging interface
5170 behind a function vector. The port to handle VxWorks targets
5171 is also part of this.
5173 All files: Replace references to renamed functions,
5174 remove references to remote_debugging, remove references to
5175 have_include_file, have_core_file in favor of target_has_stack,
5176 target_has_memory, etc.
5178 * Modularize the breakpoint interface.
5179 breakpoint.h (BREAKPOINT_MAX): New define sets max length of
5180 a breakpoint instruction.
5181 breakpoint.c: struct breakpoint's shadow_contents now sized as
5183 (insert_breakpoints): Vector to target to install breakpoints.
5184 (remove_breakpoints): Vector to target here too.
5185 Remove REMOTE_SA_SPARC kludges and other remote_debugging.
5186 sparc-tdep.c (single_step): Use new breakpoint interface for
5187 the single-step breakpoints.
5188 mem-break.c (memory_insert_breakpoint, memory_remove_breakpoint):
5189 New file, contains routines to insert and remove breakpoints by
5190 reading out the old contents and later replacing them. This is
5191 how ptrace breakpoints work, and many remote systems as well.
5193 * tm-vxworks68.h: New config file, overrides a few things for
5194 Wind River's preferences.
5196 * target.h: New file, for transfer vector used to talk to the
5197 inferior (child, attached, core, exec, remote, etc). All accesses
5198 to the thing being debugged should come through these vectors.
5199 target.c: New file, routines to handle transfer vector.
5200 (various files): Add transfer vectors XXX_ops for the various
5201 targets and pseudo-targets (core files, etc) we support.
5203 * breakpoint.c (bpstat_stop_status): Further explorations of
5204 watchpoints and why things don't work all the time.
5205 (bpstat_alloc): New fn to allocate a bpstat and chain it.
5207 * config.gdb: Only add "source ${srcdir}/.gdbinit" to
5208 the local gdbinit if it doesn't already have it.
5210 * core.c (core_ops): add and install.
5211 Allow core debugging without exec file.
5213 * dbxread.c (free_and_init_header_files): Merge two fns.
5214 (end_symtab): Free named symbol table when a new version comes in.
5215 (read_dbx_symtab): Relocate all kinds of symbols with base
5216 address. First step toward handling different text, data, bss
5218 (add_file_addr_command): Renamed add_file_command.
5219 (add_file_command): Vector to remote handler.
5220 Add "load" as an alias for "add-file" command.
5222 * defs.h: Allow "volatile" to be used in non-ANSI; use it for
5223 non-returning functions.
5225 * exec.c: Add exec_ops, and push it as a target when an exec
5228 * infcmd.c (run_command): Pass executable file name and arg list
5229 separately when starting an inferior. Permit "run" when no exec
5230 file is specified, for VxWorks.
5231 (detach_command): Move to child_detach in inftarg.c.
5233 * inftarg.c: New file. Unix-child-specific routines, and the
5234 child_ops structure.
5236 * inferior.h (registers): Export "registers" as the way for
5237 target dependent register handlers to find gdb's local copy of
5238 the registers. Rename "stop_after_attach" to "stop_soon_quietly"
5239 since it is now used by places that want wait_for_inferior to
5240 handle the grunge but want to see every trap from the inferior.
5242 * inflow.c (create_inferior): Pull out, and merge into infrun.c.
5243 Eliminate remote_debugging hooks in terminal handling.
5245 * infrun.c: Replace start_inferior with child_create_inferior.
5246 Move all the hair of Unix shells and ptrace idiosyncracies into
5247 child_create_inferior, so remote handlers don't have to deal.
5248 Remove running_in_shell. Rename stop_after_attach to
5249 stop_soon_quietly, and use it in a few other places where we want
5250 to just call wait_for_inferior and get control back on the first
5251 trap. trap_expected now never takes a value > 1.
5252 (init_wait_for_inferior): Initialize static vars when a new
5255 main.c (gdbinit): Add new hook for .gdbinit file name, let
5256 it be overridden by config files as GDBINIT_FILENAME.
5257 (DEFAULT_PROMPT): Add new hook for overriding (gdb) prompt.
5258 Both of these are used for VxWorks gdb.
5260 mcheck.c: rename include file "gmalloc.c" to avoid problems
5261 with system include file "malloc.c".
5263 param-no-tm.h: New include file, same as param.h but does not
5264 include the default "tm.h" file. This is used in files where
5265 the target is known, e.g. remote-eb.c or sparc-xdep.c.
5267 param.h: Now just a shell that includes tm.h and param-no-tm.h.
5269 remote-vx.c: New file, VxWorks remote debugging support. Uses
5270 RPC routines that are shared with the target system, in directory
5273 remote.c: Vectorize remote interface.
5275 source.c: Globalize source_path, and make an alias "l" for "list"
5276 since we now have the "load" command.
5278 sparc-xdep.c: Use new param-no-tm.h.
5280 symmisc.c (free_named_symtab): Add new function from Wind River.
5281 However, ifdef it out for now while we think about what it should
5284 tm-sun3.h, xm-sparc.h, xm-sun3.h, xm-symmetry.h: Move
5286 the xm- file, and change its name to CHILD_PREPARE_TO_STORE, since
5287 non-Unix-children handle this with their own code in the target
5290 Makefile.dist: Roll version to 3.92.3. Add vx-share stuff to
5291 source and target lists. Add vx-share to default list of include
5292 directories. Add new files to src and target lists: mem-break,
5293 target, inftarg, remote-eb, remote-vx, targ-vx. Be sure the
5294 ${srcdir} versions of munch and createtags are used.
5296 * valops.c (find_function_addr): Split out of call_function.
5297 (call_function_by_hand): Rename call_function; this function
5298 calls functions in the target by laboriously patching the target
5299 word-by-word with the right stack, args, regs, etc.
5302 Mon Nov 5 17:29:10 1990 John Gilmore (gnu at cygint)
5304 Handle AMD 29000 a bit better.
5306 * remote-eb.c (readchar): Mask received char log to make it readable.
5307 (remote_start): Pass arguments down to executing program.
5308 Make startaddr unsigned.
5309 infrun.c (start_inferior): Accept args, pass them to
5311 infcmd.c (run_command): Pass args down to start_inferior.
5313 * tconfig/am29k-aout, tconfig/am29k-coff: New files specifying
5314 the target object file format.
5315 tm-29k.h: Pay heed to COFF_ENCAPSULATE.
5317 * am29k-pinsn.c (print_insn): Print 0x on hex numbers in disassembly.
5318 am29k-tdep.c (examine_prologue): Better checking of function prefixes.
5320 Sun Oct 7 18:20:45 1990 John Gilmore (gnu at cygint)
5322 * Makefile.dist (VERSION): Roll version to 3.91.9 and freeze.
5323 * TODO: We did a few things, we have more to do though.
5325 * xm-sparc.h (CLEAR_DEFERRED_STORES): Define.
5326 * inflow.c (inferior_died): Clear deferred stores.
5328 * Debug problems with dummy frames and calls to the inferior.
5329 * tm-sparc.h (PUSH_DUMMY_FRAME, POP_FRAME): Move to sparc-tdep.c.
5330 * sparc-tdep.c (do_restore_insn): Simplify.
5331 (sparc_frame_find_saved_regs): Simplify and fix what we find.
5332 (sparc_push_dummy_frame): Simplify and fix what we push.
5333 (sparc_pop_frame): Slightly more hair here, deciding whether
5334 we are restoring a saved PC or returning to a return address in %i7.
5335 * sparc-xdep.c (read_inferior_registers): Debug if valid reg is read.
5337 * utils.c (xmalloc, xrealloc): Return type depends on __STDC__.
5338 * symtab.h (xmalloc): ditto, for obstack_chunk_alloc.
5339 * obstack.h (chunkfun): ditto.
5340 * defs.h (xmalloc, xrealloc): ditto
5342 * utils.c (quit): Grab the terminal from the child if necessary.
5344 * inflow.c (term_status_command): Rename to term_info, change
5347 * sparc-pinsn.c (print_insn): Disassembly prefers real instructions.
5348 (is_delayed_branch): Speed up.
5349 * sparc-opcode.h: Add ALIAS bit to aliases. Fix up opcode tables.
5350 Still missing some float ops, and needs testing.
5352 * Support for input and output radixes other than base 10
5353 * defs.h (input_radix, output_radix): Declare.
5354 * expread.y (yyparse, parse_number): Handle changes of input
5355 radix, and ambiguous names-or-numbers in radixes >10.
5356 * printcmd.c (print_scalar_formatted): Print formatted hex
5357 numbers in varying column widths.
5358 * valprint.c (val_print): Use output_format to print scalar ints.
5359 (set_input_radix, set_output_radix, set_radix): Create.
5360 (set_output_radix): Set output_format from output_radix.
5361 (_initialize_valprint): add `set radix' but leave the others off.
5363 * main.c (execute_command): Let stupid questions be turned off.
5364 (_initialize_main): Handle "set stupidity", etc.
5366 * main.c, inflow.c, inferior.h, frame.h, command.c, defs.h,
5367 sparc-pinsn.c, sparc-xdep.c, value.h, valops.c, values.c: Lint.
5369 Tue Oct 2 11:20:02 1990 John Gilmore (gnu at cygint)
5371 * TODO, Makefile.dist, ChangeLog: Freeze for 3.91.8 release.
5372 bfd stuff is still screwed up, but with some manual work, it
5375 * breakpoint.c (bpstat_do_actions): Start over if a command
5376 proceeds the inferior, since the inferior will have stopped and
5377 will need to have its new stop-actions taken care of.
5379 * dbxread.c (read_struct_type): Expression gives Sun3 4.0.3
5380 compiler fits, simplify it.
5382 * gdb.texinfo (directory command): Doc new dir command.
5383 source.c (directory_command): "dir" now puts things on the front
5384 of the path, moves dups up front, and handles multiple names
5385 on the command line, inserting each one in order. It also
5386 blows away cached line and full_filename info.
5388 * stack.c (backtrace_command): Skip "more stack frames follow"
5391 * Change #ifndef HAVE_VPRINTF to #define MISSING_VPRINTF in
5392 xm-convex.h, xm-hp300bsd.h, xm-isi.h, xm-merlin.h, xm-news.h,
5393 xm-np1.h, xm-pn.h, xm-pyr.h, xm-symmetry.h, xm-umax.h, xm-vax.h.
5394 The only odd one was Gould NP1, which had defined vprintf to
5397 * Merge Ted Goldstein <tedg@Eng.sun.com>'s changes for epoch.
5398 printcmd.c (print_command_1): Pass 'inspect' flag down as a global
5399 variable, inspect_it.
5400 valprint.c (print_string, val_print): Use the global inspect_it
5401 to indicate whether to print in Epoch style or normal style.
5403 Mon Oct 1 23:55:26 1990 John Gilmore (gnu at cygint)
5405 * printcmd.c (call_command): add an alias for the "print" command
5406 which runs expressions and doesn't print the result if void.
5407 (print_command_1): implement it.
5409 * command.c: Remove #if 0'd code. Initialize all the fields
5410 in add_cmd (). Rename do_nothing_command to
5411 not_just_help_class_command, and make it externally visible.
5412 command.h: add user_commands to struct.
5413 * main.c (define_command): Don't overload c->function with a char
5414 string as well as a function pointer.
5416 * eval.c (evaluate_subexp): Reinstall tiemann changes to
5417 calling convention of value_struct_elt () that got dropped in
5420 * tm-sparc.h (FRAME_FIND_SAVED_REGS): move to sparc-xdep.c.
5421 sparc-tdep.c (sparc_frame_find_saved_regs): ditto.
5423 * tm-sparc.h (POP_FRAME): replace some constants with defines.
5425 * sparc-xdep.c (store_inferior_registers): defer stores to regs
5426 until a good time (e.g. when we are about to run the child),
5427 saving ptrace calls.
5428 * infrun.c (proceed): handle DO_DEFERRED_STORES.
5429 * tm-sparc.h: define DO_DEFERRED_STORES.
5431 * sparc-xdep.c (store_inferior_registers): when storing float
5432 registers, don't store stack regs too. When storing the SP,
5433 however, DO store the stack regs too. This fixes a bug in which
5434 the dummy frame is not recognized when a call_function finishes,
5435 because its frame pointer (in the stack regs) was never
5437 (read_inferior_registers): Mark WIM and TBR and FPS and CPS valid
5438 even though we don't know how to read them from an inferior.
5439 valops.c (call_function): Comment about storing SP.
5441 * infrun.c (save_inferior_status): Save away the original bpstat
5442 chain so it can be restored later. Install the copied version for
5443 use by whoever saved the status. It will be blow away by
5444 restore_inferior_status, and the original chain restored. This is
5445 important for people who have pointers into the original.
5447 * breakpoint.c, command.h, copying.awk, dbxread.c, defs.h,
5448 findvar.c, frame.h, obstack.h, obstack.c, inflow.c, value.h,
5449 main.c, printcmd.c, sparc-tdep.c, symtab.c, valprint.c: lint
5452 Fri Sep 28 20:32:46 1990 John Gilmore (gnu at cygnus.com)
5454 * Makefile.dist: Roll version to 3.91.8. Add bfd.h and bfdconfig.h
5455 temporarily to the makefile. Add am29k-opcode.h and WHATS.NEW.
5456 Add stuff.c and kdb-start.c to the OTHERS list for tar files.
5458 Fri Sep 28 19:12:12 1990 John Gilmore (gnu at cygint)
5460 * Merge Mike Tiemann's multiple inheritance changes from Sun.
5461 Store the baseclasses in a type struct starting from array element
5462 0 rather than from the unusual array element 1.
5464 dbxread.c: the above.
5465 (virtual_context): Add
5466 Read new debug information about which virtual function table
5467 a virtual function is from, and store it in fn_field.fcontext.
5469 symtab.h: Add fcontextt. Fix baseclass indices. Typo in
5470 TYPE_FN_FIELD_STATIC_P.
5472 symtab.c: the above.
5473 valops.c: the above. Handle pointer casts of object *'s.
5474 (search_struct_method): Add.
5475 (value_struct_elt): First arg is now a pointer to a value, and is
5478 valprint.c: the above.
5479 values.c (value_virtual_fn_field): Add type arg. Handle
5480 offsetting to the proper object when calling virtual fns.
5482 (baseclass_addr): Add valuep arg.
5484 * README: Document the current state of BFD config (missing).
5485 * TODO, ChangeLog, Makefile.dist: Roll version.
5486 * WHATS.NEW: Add summary of changes since 3.5.
5488 Thu Sep 27 16:23:12 1990 John Gilmore (gnu at cygint)
5490 * dbxread.c (read_struct_type): Clear bit vectors whenever
5492 symtab.c (B_CLRALL): define.
5494 * tm-sparc.h (STORE_RETURN_VALUE): Avoid clobbering types by
5495 using == rather than =. Huh... This fixes the dreaded problem
5496 wherein builtin_type_int becomes TYPE_CODE_FLT.
5498 * core.c (info_files): Show the inferior pid.
5500 * config.gdb: Avoid putting "dir" command into .gdbinit. GDB
5501 already knows how to look in the source directory.
5503 * Remove psymtab hair from many places. Remove duplicated code
5504 for searching symbol tables. Hide psymtabs from most places.
5505 Make it fast to get from a psymtab to its symtab.
5507 blockframe.c (blockvector_for_pc): Remove psymtab hair.
5508 coffread.c (psymtab_to_symtab): Rename to psymtab_to_symtab2.
5509 mipsread.c (psymtab_to_symtab): Rename to psymtab_to_symtab2.
5510 dbxread.c: export psymtab_to_symtab, make it work if called N times.
5511 (psymtab_to_symtab): Rename to psymtab_to_symtab2. Initialize
5512 new symtab completely. New psymtabs get symtab pointer
5513 initialized to zero. Remove MI warning printf.
5514 symtab.h: Comments. Add psymtab to symtab pointer.
5515 (PSYMTAB_TO_SYMTAB): New macro.
5516 symtab.c: use PSYMTAB_TO_SYMTAB. Add psymtab_to_symtab and export it.
5517 source.c: use PSYMTAB_TO_SYMTAB. Remove symtab version and
5519 stack.c (backtrace_command): Avoid pre-pass to read symbols, if
5521 (print_frame_info): Avoid special-casing symbols that have not yet
5524 * source.c (open_source_file): Quick path if we have already
5525 located the source file by its full name.
5527 * symtab.c (lookup_symbol): Use find_pc_symtab rather than
5528 find_pc_psymtab. When a name is found in the misc function
5529 vector, search the symbol table for its mangled name, not the
5530 name that the user typed.
5532 * bfd.h: Fix missing comment terminators, make #endifs match.
5534 * valarith.c (value_less): Handle unsigned int comparisons.
5535 Add FIXME about pointer compares, which assume host and target
5536 pointers are the same.
5538 * command.c (do_nothing_command): lint
5539 dbxread.c: lint. Remove sort_syms. Document C++ visibility info,
5540 fix comments on debug symbol format for visibility. Actually set
5541 visibility of symbols.
5542 main.c (echo_command): lint; use <readline/history.h>.
5543 tm-sparc.h (FRAME_FIND_SAVED_REGS): lint
5544 obstack.h (_obstack_blank): Rearrange pointer math to avoid
5545 pointing past end of allocated memory; saber complains.
5546 obstack.h: Declare the external functions that we use.
5547 valarith.h: use <string.h>
5548 solib.c (solib_add): lint.
5550 Fri Sep 21 17:05:19 1990 John Gilmore (gnu at cygint)
5552 * main.c (initialize_main): Default info_verbose to off, now that
5553 symbol reading is fast.
5554 (quit_command): Avoid clobbering exec_bfd while quitting.
5556 * Initial BFD (binary file diddling library) merger:
5557 coffread.c: Change AOUTHDR to struct exe_hdr.
5559 core.c: initialize initialized data at compile time.
5560 (core_file_command): Move from coredep.c, convert to bfd.
5561 (xfer_core_file): Convert to bfd.
5562 exec.c (exec_file_command): use bfd routines.
5564 mips-tdep.c: Remove exec_file_command and friends.
5567 * coredep.c: (fetch_core_registers) Convert core_file_command to
5568 fetch_core_registers.
5569 mips-xdep.c, sparc-xdep.c, sun3-xdep.c: ditto.
5571 * utils.c: (error): Bogus crap, FIXME, to print bfd errors.
5572 (my_bfd_read): More bogosity, which I don't think we call.
5573 (program_name): Remove this atrocity asap!
5575 Wed Sep 19 13:36:41 1990 John Gilmore (gnu at cygint)
5578 values.c: allocate_repeat_value was not clearing the
5579 optimized_out field.
5580 (value_static_field): minor stylistic fix (wrong macro was used).
5581 valops.c (value_struct_elt_for_address): didn't work for C++
5584 * signame.c (_initialize_signame): Initialize signal names once.
5586 * breakpoint.h, command.c, copying.awk, defs.h, environ.c,
5587 exec.c, frame.h, infcmd.c, inferior.h, main.c, munch, sun3-xdep.c,
5588 symtab.h, tm-29k.h, valprint.c, value.h, values.c: Lint.
5590 * remote-eb.c: Support user-settable baud rates on the serial port.
5592 * tm-sun3.h (PREPARE_TO_STORE): fix typo.
5594 Fri Sep 14 13:28:29 1990 John Gilmore (gnu at cygint)
5596 * tconfig/sun3os4: Remove warning about native assembler,
5597 since it also occurs in the xconfig file.
5599 * findvar.c (registers): Allocate some slop after `registers'
5600 to prevent stray accesses from trashing the next variable.
5602 * tm-68k.h (REGISTER_BYTES): Allocate the right number of bytes
5603 on the sun-3, by changing the #ifdef from `sun3' (which is not
5604 defined by cc) to `sun'. Symptom was trashed builtin_type_XXX
5605 vars, which happened to follow `registers' in the executable.
5607 * readline/history.c (history_search): Heed gcc-2's advice
5608 and parenthesize && inside ||).
5610 * am29k-opcode.h, am29k-pinsn.c, am29k-tdep.c, remote-eb.c,
5611 tm-29k.c: Insert FSF copyright headers.
5613 * remote-eb.c: Better comments.
5615 * Makefile.dist: Update to 3.91.6.
5616 * TODO: note PREPARE_TO_STORE problem.
5618 Thu Sep 13 09:52:33 1990 Jim Kingdon (kingdon at cygint)
5620 * stack.c (frame_info): Only use FRAME_FIND_SAVED_REGS if defined.
5622 * remote.c: Wrap the whole file in #if !defined (SPECIAL_REMOTE).
5624 * infrun.c (wait_for_inferior, at end): Don't set up
5625 prev_* if the inferior no longer exists.
5627 * inferior.h (CALL_DUMMY_LOCATION): New macro, to replace
5628 CANNOT_EXECUTE_STACK.
5629 valops.c (call_function): Use it.
5631 * tm-convex.h: Add CALL_DUMMY_LENGTH for use by PC_IN_CALL_DUMMY.
5633 * inferior.h (PC_IN_CALL_DUMMY): New macro.
5634 infrun.c (wait_for_inferior, 2 places): Use it.
5636 * values.c (value_being_returned): Only use
5637 EXTRACT_STRUCT_VALUE_ADDRESS if defined.
5639 * Move PREPARE_TO_STORE from xm-sun3.h to tm-sun3.h to do the
5640 right thing for remote-eb.c.
5642 * sun3-xdep.c: Remove extraneous call to remote_store_registers.
5643 * sun386-xdep.c, hp300hpux-xdep.c, sparc-xdep.c: Ditto.
5645 * blockframe.c: Put get_frame_saved_regs inside #if !defined
5646 (FRAME_FIND_SAVED_REGS).
5648 * findvar.c ({fetch,store}_registers): Check for
5649 REMOTE_{FETCH_STORE}_REGISTER macro.
5651 * findvar.c (get_saved_register): Add argument lval and
5652 change meaning of argument addr.
5653 findvar.c: Change calls to get_saved_register to reflect
5654 new calling convention.
5655 valops.c (value_assign): Use get_saved_register instead of
5656 find_saved_register.
5658 Sun Sep 2 12:40:20 1990 Jim Kingdon (kingdon at cygint.cygnus.com)
5660 * coffread.c (read_one_sym): Make temp_aux an AUXENT, not
5661 an (uninitialized) pointer to one. Use "&" when passing it
5664 Fri Aug 31 22:57:54 1990 Jim Kingdon (kingdon at cygint.cygnus.com)
5666 * coffread.c (getfilename): Use DGUX x_offset and x_name if
5669 * coffread.c (symbol_file_command): Put semicolon after
5671 Put safe_to_init_tdesc_context in #if defined (TDESC).
5672 Put #ifdef TDESCs in 1st column for non-ANSI cpp's.
5673 coffread.c: #include <sys/stat.h>.
5674 (read_coff_symtab): Typo: in_source_files -> in_source_file.
5675 Add missing ')' in check for "lc%" and friends. Remove
5677 Declare read_one_sym() at top of file.
5678 (read_file_hdr): Put in extra #ifdefs so MC68MAGIC and
5679 MC68WRMAGIC can have the same value without causing a duplicate
5682 Thu Sep 13 15:55:36 1990 John Gilmore (gnu at cygint)
5684 * Allow a Makefile to be built without building the
5685 tm and xm file links that screw up builds in subdirectories.
5686 This is done with `config.gdb none', then you can do things
5687 like `make gdb.tar.Z'.
5688 * tconfig/none: Config file for no target system
5689 * xconfig/none: Config file for no host system
5690 * config.gdb: If no TM or XM files are called out by the
5691 host or target file, don't make links for them.
5693 * cplus-dem.c: Add documentation.
5695 * dbxread.c (read_ofile_symtab): Turn a fatal error into a
5696 simple error, so the user's gdb doesn't crash due to some object
5697 file problem (e.g. somebody is rebuilding the file out from under
5700 * printcmd.c (print_address_symbolic): demangle the symbol.
5702 * Makefile.dist (OTHERS): Remove tdesc-lib because it has
5703 Motorola copyrights in it. Make "make gdb.tar.Z" work.
5704 (alldeps.mak): sort and uniq all results from this; duplicates
5705 hose gdb.tar.Z link building. Remove RCS files from
5706 tconfig and xconfig. Add config files for sun386. Add
5707 a few odd files to OTHERS and HFILES.
5709 Mon Sep 10 21:20:24 1990 John Gilmore (gnu at cygint)
5711 * Makefile.dist: Pull solib.c to tconfig/sun?os4.
5712 Roll version number to 3.91.5. Make lint work in bindir.
5714 * README: Document cross-debugging and new file structure.
5716 * blockframe.c: Lint. Include "value.h" to declare read_register.
5717 (find_pc_partial_function): remove duplicate line.
5719 * command.h: Lint. Declare error_no_arg and dont_repeat.
5721 * tm-news.h: Remove inadvertently duplicated stuff.
5723 * mipsread.c: Remove cache_pc_function stuff, now done cleanly.
5724 Clean up usage of misc_function_type. Declare some CORE_ADDRs.
5726 * config.gdb: Allow `config.gdb host target' form. Clean
5727 up previous change that printed bogus messages when you just said
5730 * core.c: #include "command.h" for lint.
5733 * main.c: Remove some casts of enums. Lint.
5740 * printcmd.c (initialize_printcmd): Fix thinko in inspect cmd.
5742 * sparc-tdep.c (isannulled): Take instruction as parameter, don't
5743 read it from memory. This will allow us to save ptrace calls
5744 eventually. Changed caller single_step too.
5746 * sparc-xdep.c (fetch_inferior_registers): Avoid reading regs
5747 that we aren't going to use, saving many ptrace calls, especially
5748 when watchpointing or single stepping. Use some #define's for
5750 (store_inferior_registers): Ditto.
5751 (core_file_command): Use some #define's for constants.
5753 * tm-sparc.h: Add #define's for some register numbers, so we
5754 can eliminate the use of random constants in sparc-xdep.c.
5756 * stack.c (frame_command, print_frame_info, up_command,
5757 down_command) Remove frame_changed, since it
5758 causes a bug and doesn't seem to do anything useful. In some
5759 places it was used as a flag, in others as a stack level (?).
5761 * utils.c: Use MISSING_VPRINTF rather than HAVE_VPRINTF, so the
5762 default is to use the portable (vprintf) version rather than the
5764 * xm-news.h (MISSING_VPRINTF): Add.
5766 * valprint.c (val_print): Demangle fancy vtbl printouts. Lint.
5768 Sat Sep 8 00:24:12 1990 John Gilmore (gnu at cygint)
5770 * Remove stuff that forces -Bstatic linking of gdb, and warnings
5771 about linking debugged programs -Bstatic in the sun?os4 config
5772 files in tconfig and xconfig subdirectories.
5774 * main.c (main): Remove unreached exit(0) now that we exit
5777 * Create TODO file for online bug list. There are too many
5778 "little" bugs to keep track of on paper.
5780 * Change Projects file to refer to bug-gdb@cygnus.com
5781 rather than kingdon@ai.
5783 Fri Sep 7 23:35:15 1990 John Gilmore (gnu at cygint)
5785 * Makefile.dist (VERSION): 3.91.4 now.
5787 * symtab.c (init_misc_bunches): Rename from init_misc_functions.
5788 (condense_misc_bunches): Add sanity check that misc_count is
5789 the same as the number of symbols in the bunch.
5791 * coffread.c: rename init_misc_bunches. Pass an argument
5792 to condense_misc_bunches (a zero).
5794 * dbxread.c (partial_symbol_file_read): Call init_misc_bunches
5795 every time we are called; don't rely on our caller to do it.
5796 (add_file): Remove call to init_misc_bunches.
5798 * mipsread.c: Only warn, don't error, if unknown symbol types.
5799 This keeps an old gdb from falling on its face if it sees newly
5800 extended symbol info. Rename init_misc_bunches.
5802 Fri Sep 7 22:58:15 1990 John Gilmore (gnu at cygint)
5804 * Merge in changes from Per Bothner for DECstations and other
5805 MIPS stuff. The rest is Bothner speaking:
5807 The next message is a merger of Alessando Forin's mips port with
5808 mine. I've tried to use my good if biased judgment to get
5809 the best of both. It *does* need testing.
5811 Some of the changes are general, *not* mips-specific.
5814 Didn't believe in little-endian bit order.
5815 There are still inconsistencies about whether flags
5816 like BITS_BIG_ENDIAN are integer (#if ...) or
5817 boolean (#ifdef ...). I tried to paper over them.
5819 dbxread.c,coffread.c,mipsread.c,symtab.c,symtab.h:
5820 Moved some misc_function code that was common to
5821 {dbx,coff,mips}read.c to symtab.c.
5822 In the process, I think I cleaned things up a bit.
5823 At the same time, moved obsavestring and obconcat to symtab.c.
5826 Removed obsolete condense_addl_misc_bunches (use
5827 condense_misc_bunches(1) instead).
5830 Needed to include <sys/dir>, at least on DECstations.
5832 valops.c, mips-tdep.c, tm-mips.h:
5833 Added PUSH_ARGUMENTS macro to support funny argument-pushing
5834 conventions (when STACK_ALIGN is insufficient).
5835 Needed on mips, where doubles need 8-byte alignment,
5836 but ints only need 4.
5839 Removed cruft that was not being used.
5840 Merged in many fixes (most from Frank Yellin, fy@lucid.com).
5843 Print $ before register-names (I think that makes things a little
5845 Never print two instructions, even if one delays.
5846 Removed hex-disassemble set_cmd. (This is not mips-specific,
5847 so I think the argument is whether it is generally worthwhile or not.
5848 I'm inclined to think not, given how easy it is to
5849 convert between radixes in gdb.)
5852 This is basically Alessando's code.
5853 It doesn't use obstacks; I changed it to use obstacks
5854 in a few minor places where using malloc causes a
5855 memory leak. (Probably, more places could/should be changed.)
5856 I added record_misc_function where it was missing.
5857 In symbol_file_command and add_file_command, I tried
5858 to make the code consistent with more recent versions.
5859 Minor sylistic changes in parse_procedure.
5860 Make a .gdbinfo. psuedo-symbol point back to the real
5861 procedure symbol (using the isym field).
5864 This is basically from my port, but with a lot of details
5865 and a number of routines merged in from Alessando's version.
5866 I basically used my code "raw" backtrace (use heuristics
5867 from the actual code, rather than symbol table info) - though
5868 the idea is Alessandro's. I feel my code is a little cleaner
5869 here, particularly in being a little more flexible, such as being
5870 able to handle gcc-produced code (which it now can).
5871 It also doesn't do frame caching (which is not useful
5872 more recent gdb versions).
5873 I also used my code for push_/pop_dummy, more or less.
5874 I tried to incorporate AF's code for testing sigtramp
5875 while backtracing; I probably got it wrong.
5876 Added mips_print_register, which tries to scrunch as much
5877 information as possible on a screen...
5878 Removed the skip-prologue set_cmd. As with hex-disassemble (see
5879 under mips-pinsn.c), I don't see anything mips-specific here,
5880 and I don't see it being all that useful anyway.
5883 Added a $fp psuedo-reg distinct from $fp (nice for gcc).
5884 Use more register names (rather than hard-cases numbers).
5886 Thu Sep 6 18:33:15 1990 John Gilmore (gnu at cygint)
5888 * Hack up 3.90.11 changes:
5890 * Makefile.dist (depend): parameterize $(GCC).
5891 Add solib.c and solib.o.
5892 (readline): Fix vpath for both absolute or relative SRCDIR.
5894 * blockframe.c: Fix from Schaefer@asc.slb.com for shared libs.
5895 Also, let the part I didn't understand at least compile so
5896 I can test the rest. FIXME.
5898 * dbxread.c: Fix thinko using strcmp.
5899 (init_psymbol_list): declare static.
5900 (partial_symbol_file_open): Comment cleanups better, avoid
5901 cleaning up the string table since the caller will do that.
5902 Move the stat for mod time into symbol_file_command, temporarily.
5903 (There should be a mod time for each symbol file, eventually,
5904 to control its rereading. FIXME.)
5906 * infptrace.c (PT_WRITE_D): use same value as PT_WRITE_I for
5907 SunOS, which gives error for shared libs otherwise. (From
5908 Schaefer, probably FIXME needs work for portability.)
5910 * solib.c: Move #include "param.h" to work.
5911 Lowercase all the Uppercase Letters In the Messages.
5912 (find_solib): Clean up inferior_so_name for debug printouts.
5913 Allow no argument, to mean all shared libraries.
5915 * symmisc.c: include param.h to get CLEAR_SOLIB.
5917 Wed Sep 5 18:00:08 1990 John Gilmore (gnu at cygint)
5919 * Merge in Kingdon's changes from FSF: the diffs from 3.90.9
5920 to 3.90.11. ChangeLog entries below are from this.
5922 Wed Jun 13 09:17:39 1990 Jim Kingdon (kingdon at mole.ai.mit.edu)
5926 * Makefile.dist (HFILES): Add tm-sunos.h.
5928 Tue Jun 12 16:15:26 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5932 * Makefile.dist (gdb.tar.Z): Change linking of config so it works.
5934 Thu Jun 7 16:22:27 EDT 1990 Jay Fenlason (hack@ai.mit.edu)
5936 * sparc-opcode.h Added single-operand version of rett.
5938 Mon Jun 4 18:12:31 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5940 * m-sparc.h (REG_STRUCT_HAS_ADDR, STRUCT_ARG_SYM_GARBAGE):
5941 Put parens around gcc_p in expansion.
5943 Thu May 24 15:44:51 1990 Jim Kingdon (kingdon at mole.ai.mit.edu)
5945 * utils.c (lines_to_list): Return 10 if lines_per_page == 0.
5947 Wed May 23 16:36:04 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5949 * Changes for Sun shared libraries:
5950 blockframe.c (find_pc_partial_function): If a non-text symbol
5951 is found, set *address = pc - FUNCTION_START_OFFSET.
5952 breakpoint.c (insert_breakpoints) [DISABLE_UNSETTABLE_BREAK]:
5953 Disable breakpoints instead of giving an error.
5954 source.c (select_source_symtab): Initialize cs_pst.
5955 symmisc.c: Call CLEAR_SOLIB if defined.
5956 symtab.h: Make text{low,high} CORE_ADDR not int.
5957 (psymtab): New field addr.
5959 dbxread.c: Move DECLARE_FILE_HEADERS outside functions.
5960 (record_misc_function): Give correct type for N_DATA symbols.
5961 (condense_misc_bunches): do "misc_function_count = j" regardless
5963 Take code which is shared between symbol_file_command and
5964 add_file_command and put it into partial_symbol_file_{open,read}.
5965 Split add_file_command into add_file_command and add_file.
5966 Make psymtab_to_symtab read in the string table if the file
5968 Two new parameters to read_dbx_symtab and start_psymtab.
5969 tm-sunos.h: New file.
5971 Tue May 22 17:43:03 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5973 * infcmd.c: Change cont_command to continue_command and "cont"
5976 Mon May 21 14:41:41 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5978 * breakpoint.c (enable_breakpoint): Get value of watchpoint.
5980 * defs.h [sparc]: Use <alloca.h> regardless of __GNUC__.
5982 * values.c (USE_STRUCT_CONVENTION): Check for structures of
5983 size 1,2,4,8 rather than size < 8.
5985 * dbxread.c (dbx_lookup_type): Do f->length *= 2 as many times
5986 as necessary, not just once.
5988 * sparc-opcode.h: Add a bunch of new opcodes which Sun as supports.
5990 Thu May 17 15:04:09 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5992 * {t,x}m-sun386.h, sun386-xdep.c, {x,t}config/sun386
5994 * tm-news.h: Add CALL_DUMMY_*.
5996 * tm-68k.h: Remove duplicate comment at FRAME_FIND_SAVED_REGS.
5998 * config.gdb: In list_host, list_target, use ${i}, not $i.
6000 Tue May 15 21:27:12 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
6002 * source.c (find_source_lines) [BROKEN_LARGE_ALLOCA]: Use xmalloc.
6004 * sparc-opcode.h: Change all store floating-point state register
6005 instructions to have the right match & lose fields.
6007 Sat May 5 12:39:18 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
6009 * Makefile.dist: Move -I${srcdir} to GLOBAL_CFLAGS and pass
6011 config.gdb: If srcdir != ., create readline directory and
6012 copy a makefile into it.
6014 * wait.h, infrun.c: Change WRETCODE to WEXITSTATUS for
6015 consistency with POSIX.
6017 * breakpoint.c (bpstat_stop_status): Disable watchpoint
6018 when we exit its exp_valid_block.
6020 Tue Sep 4 11:46:46 1990 John Gilmore (gnu at cygint)
6022 * Makefile.dist: Bump version to 3.91.3.
6024 * Clean up handling of breakpoint commands (somewhat).
6025 Prompted by Tiemann bug report "cont 10" doesn't work any more.
6027 inferior.h: Add breakpoint_proceeded to inferior status struct
6028 and globals; save it and restore it.
6029 (clear_breakpoint_commands): Cleanup, remove old #define.
6031 infrun.c (clear_proceed_status): Set breakpoint_proceeded.
6032 (save_inferior_status, restore_inferior_status): handle it also.
6033 (proceed): Remove earlier code that set breakpoint_proceeded.
6034 It is now set only in clear_proceed_status.
6035 (clear_proceed_status): Cleanup, use bpstat_clear rather
6036 than clear_breakpoint_commands. No callers need the stop_bpstat
6037 between clear_proceed_status and proceed.
6039 infcmd.c: Add breakpoint_proceeded definition and comment.
6040 (cont_command, jump_command, signal_command): Move call to
6041 clear_proceed_status right next to call to proceed.
6043 breakpoint.c (bpstat_do_actions): Avoid clobbering our
6044 caller's argument while running down the chain of breakpoints.
6045 Use new variable "breakpoint_proceeded" to determine when
6046 a command that it executes moves the inferior past the
6048 (bpstat_clear): Handle NULL argument.
6049 (bpstat_clear_actions): Avoid useless call to
6050 breakpoint_auto_delete.
6051 (delete_breakpoint): Clean up bpstat's that are pointing to
6052 the deleted breakpoint from the stop_bpstat chain.
6053 (breakpoint_auto_delete): Simplify.
6055 * Clean up handling of EOF, error on stdin, etc. This was
6056 prompted by a network problem that caused gdb to go into an
6057 infinite loop filling up its malloc'd memory.
6059 main.c (return_to_top_level): Cleanup: call bpstat_clear_actions,
6060 not clear_breakpoints_commands, which is now gone.
6061 (main): If command_loop returns (e.g. from EOF on stdin), do
6062 a quit_command (looping back to command_loop if quit_command
6063 doesn't really quit).
6064 (command_loop): check result from command_line_input and
6065 exit if it returns NULL, rather than passing the NULL to
6067 (gdb_readline): Free malloc'd result space before returning
6070 * utils.c (query): Handle C-d to mean "yes", just as if the
6071 input was not a terminal. Also avoid infinite loop if EOF
6072 occurs in mid-input-line before newline. This allows
6073 query to be used at EOF on stdin with reasonable results.
6075 * infrun.c (proceed): Set breakpoint_proceeded.
6077 * values.c (value_as_long): Avoid infinite recursion for enums.
6078 (_initialize_values): Fix typo in help msg (kingdon).
6080 * Makefile.dist (RL_LIB): Use RL_LIB_DEP for dependencies,
6081 RL_LIB for linking. This allows -lreadline for linking
6082 and nothing for dependencies, once readline is a real library.
6084 * config.gdb: Jim Kingdon: give useful error message if the
6085 host or target type is not recognized.
6087 * defs.h (alloca): SPARC <alloca.h> does not declare alloca,
6088 it just defines it. Dumb, but deal with it.
6090 * Jim Kingdon suggests:
6091 in xconfig/sun3os4, CFLAGS should be XM_CFLAGS.
6093 Wed Aug 29 18:03:27 1990 John Gilmore (gnu at cygint)
6095 * Makefile.dist (VERSION): Bump version # to 3.91.2.
6097 * Clean up Bothner's changes.
6099 * blockframe.c (clear_pc_function_cache): New function.
6100 * blockframe.c: remake cache_pc_function_* static.
6101 * dbxread.c (symbol_file_command): remove references to
6102 cache_pc_function_* variables.
6103 * dbxread.c (read_struct_type): Use VOFFSET_STATIC.
6104 * printcmd.c: Avoid kludging a global variable (addressprint)
6105 to avoid printing the address of a string twice. Instead,
6106 pass the format letter 's' down low enough that it can be seen
6107 to avoid this problem.
6108 (print_formatted): Pass format arg to value_print.
6109 (restore_addressprint): Remove function.
6110 (do_examine): Avoid hacking addressprint, cleanups and such.
6111 (print_frame_args): Add a comment to a Bothner change.
6112 * symtab.h: define VOFFSET_STATIC and use it instead of "-1".
6113 * symmisc.c (free_all_symtabs): Call clear_pc_function_cache
6114 to wipe out the values cached in blockframe.c.
6115 * symtab.c (find_method): Add comment saying how big you must
6116 allocate to be "big enough". Per being terse again.
6117 * valprint.c (val_print): Handle format letter "s" to print
6118 strings without addresses. Add comment to vtbl printing code
6119 which casts with wild abandon. Rearrange reference-printing
6121 @0xaddr: value (print w/addressprint)
6122 value (print w/~addressprint)
6123 @0xaddr (parameter lists w/addressprint)
6124 or nothing (parameter lists w/o addressprint)
6126 Tue Aug 28 10:47:18 1990 John Gilmore (gnu at cygint)
6128 * Merge more changes from Per Bothner:
6130 Gdb's handling of TYPE_CODE_REF was so counter-C++ (and otherwise
6131 annoying) that I tried to improve it. Here are my suggestions.
6133 These patches all attempt to handle TYPE_CODE_REF (as in C++) better.
6136 Do automatic de-reference when taking the address of a reference.
6138 Don't deref_ref when printing parameter lists.
6140 More attempts at treating refernences properly.
6142 In val_print, if deref_ref==0, don't print dangling " = ".
6144 Add COERCE_REF macro, which de-references an REF.
6146 * Merge changes from Per Bothner:
6148 * Fixed (Sony news)-specific configuration problems.
6149 * Fixed other problems with using vanilla pcc and libc (enum problems;
6150 assumption that vsprintf exists).
6151 * Some major speed-ups (finc_pc_partial_function now caches a match;
6152 parsing avoids duplicate symbol_lookup calls).
6153 * Changed handling of baseclasses (no longer use baseclasses field
6154 of struct type, use the first n_baseclasses fields instead).
6155 * Various minor changes/fixes, most C++-related.
6158 Cache the most previous match from find_pc_partial_function.
6159 (Save both low and high ends of matching function's pc range.)
6160 This speeds up the loop of infrun.c:wait_for_inferior quite
6161 a bit, and makes step/next commands much zippier.
6163 Added an enum->int cast (otherwise, some compilers barf).
6165 No longer set baseclass offset to 0, since multiple
6166 inheritance now mostly works.
6167 Added a number of casts, to shut up compiler warnings
6168 (after stabs where made enums, not ints).
6169 When discarding a symbol table (in symbol_file_command),
6170 must clear the cache introduced in blockframe.c.
6171 Don't convert $vtbl_ptr_type to vtbl any more.
6172 Get rid of TYPE_BASECLASEES and baseclass_vec (see also symtab.h).
6173 Mask off sign bit emitted by g++ for virtual table offset.
6174 Set voffset to -1 (not 1) for static member functions.
6176 Changed parsing/lexing of names to avoid doing symbol lookup twice
6177 (once when lexing to determine symbol class, once for real).
6178 Now only call symbol_lookup once. Fields of 'this' win especially big.
6180 Subpress printing addr twice in the case of 'x/s addr'.
6182 lookup_basetype_type is no longer used.
6183 Add find_methods as recursive helper function to decode_line_1.
6184 This allows multiple inheritance to work.
6185 Also, once one or more matches has been found, do not look in
6186 base-classes. (Baseclass methods would be overridden, anyway.)
6188 Removed baseclasses array in struct type.
6189 Instead of using baseclasses[i], use fields[i-1].
6190 Added virtual_field_bits[i] to indicate if the i'th baseclass is virtual.
6191 Changed sign convention of voffset (previous was inconsistent).
6193 Some macros (CALL_DUMMY and relatives) were missing. Put them back.
6195 Used to assume existence of vsprintf. Re-written to not need it
6196 if HAVE_VPRINTF is undefined.
6198 typecmp was too pessimistic. Made it less so.
6200 Don't print space after address.
6201 If vtable points to a misc symbol (with 0 offset), print it,
6202 since that indicates the actual class of the object.
6203 Changed ype_print_derivation_info to use new inheritance
6204 scheme (without baseclasses vector).
6206 In value_primitive_field, fixed some bugs left over from previous set of fixes.
6207 Also, changes needed because TYPE_BASECLASSES were removed.
6209 REGISTER_U_ADDR didn't work for PC. Rewrote to use an array.
6211 Tue Aug 21 20:08:54 1990 John Gilmore (gnu at cygint)
6214 If there is no path set, and the symbols don't indicate what directory
6215 a file was compiled in, look in the current directory. But either
6216 a path or a known compilation directory will prevent this.
6219 Three independent bug fixes:
6220 * Remove the #if 0 block that breaks some stuff.
6221 * SunOS 4.1 fixed the promoted-parameter-wrong-addr bug in Sun C;
6222 adapt gdb to either SunOS 4.0.* or 4.1.
6223 * MAX_OF_TYPE and MIN_OF_TYPE thinko. By tedg@sun, I think.
6226 Instantiate the class T when looking for methods in it. (Tiemann@sun)
6229 (type_print) Demangle the name being printed.
6230 (type_print_base) Handle botched demangling without coredump (tiemann).
6233 (check_stub_method): Document routine.
6234 (tiemann) fix bug for no-arg functions
6235 Avoid clobbering beyond end of malloc'd storage.
6236 Terminate the argument list properly.
6238 Sat Aug 18 01:29:59 1990 Per Bothner (bothner@cs.wisc.edu)
6240 * Changes merged by John Gilmore:
6243 In breakpoint_1, use new print_address_symbolic instead
6244 of find_pc_partial_function. (This forces use of assembler-level
6245 addresses, and avoids misleading non-mangled source-level names.)
6247 Generalize ansi argument such that -1 means skip arglist totally.
6248 Removed global variable print_ansi_qualifiers (which made
6249 code non-reentrant), in favor of extra explicit arguments
6250 to internal routines.
6252 Add new helper function print_address_symbolic.
6253 Use find_pc_misc_function instead of find_pc_partial_function
6254 (since we want assembler-level symbols here).
6256 Print unknown function as just "f (...)", not "f (...) (...)".
6257 Use new fputs_demangled explicitly.
6259 Fixed a typing violation (problem: value.h cannot be imported
6260 without renaming many variable in this file).
6261 lookup_symbol: If no matching misc_func, look for a C++-mangled name.
6262 decode_line_1: Moved forward some never-reached code.
6263 Made decode_line_2 skip function prologues correctly.
6265 fputs_filtered should not demangle by default.
6266 Add new fputs_demangled to demangle on demand..
6268 Change value_struct_elt to use value_primitive_field (using recursive
6269 utility function search_struct_field). This allows foo.bar to work
6270 for multiple inheritance (so far only for data fields).
6271 Change check_field in the same way (recursive helper function
6272 to support multiple inheritance).
6273 (Note: there are more of these problems that I haven't fixed.
6274 Any code that says TYPE_BASECLASS (t, 1) is probably wrong.)
6275 value_of_this: 'this' symbol name is now just "this", note "$this".
6277 Don't print static members.
6278 Avoid printing "members of <type>" if there are none.
6279 Simplified type_print_derivation_info by merging duplicate code.
6280 Remove useless blank lines in type_print_base (ptype command).
6282 Added declaration of new routine value_primitive_field.
6284 Added value_primitive_field which is generalized version of
6285 value_field that can handle multiple inheritance (non-zero offsets etc).
6286 Re-implemented value_field to call value_primitive_field.
6288 Fri Aug 17 23:33:44 1990 John Gilmore (gnu at cygint)
6290 * infcmd.c -- insert else to avoid 'delete env' coredump when you
6291 delete the whole environment. Karl Berry reported the bug.
6292 * source.c - fix openp to avoid //'s in filenames, which
6293 trigger an Emacs bug causing it to not be able to find files
6294 when running gdb in a window.
6295 * dbxread.c - zap the #if 0 that botches the add-file code.
6296 It seems to work a lot better without all the code commented out.
6298 Fri Jul 20 16:58:46 1990 John Gilmore (gnu at cygnus.com)
6300 * Merge Tiemann's and Ted Goldstein's changes, detailed below,
6303 Tue Jul 17 19:34:33 1990 Ted Goldstein (tedg at golem)
6305 * Makefile - added a ${CFLAGS} to a couple of entries,
6306 added remote-sa.sparc.c
6307 * added remote.sa-sparc.c, a modification of remote.c
6308 which conducts a dialog directly with the SparcStation prom.
6309 * breakpoint.c, infrun.c, sparcdep.c added
6310 remote_insert_breakpoint(), and remote_remove_breakpoint()
6311 to breakpoint.c instead of directly writing breakpoint instructions.
6312 * sparcdep.c on remote_debugging,there is no need
6313 to remove signle step breakpoint instructions.
6314 * main.c added "-epoch" flag and "int epoch_interface" to main.c
6316 * printcmd.c - epoch interface sends lisp expressions to open up
6317 epoch windows on inspection.
6318 * valprint.c - added arrayprint, and addressprint and made adding
6319 format controls easier
6320 * wait.h added a couple of undef's because we were getting
6321 complaints about WSTOPSIG and WTERMSIG begin redefined.
6324 Wed Jul 4 05:27:51 1990 Michael Tiemann (tiemann at masham)
6326 * symtab.c (decode_line_1): Add support for handling method stubs
6327 in the type information.
6329 Tue Jul 3 09:39:18 1990 Michael Tiemann (tiemann at masham)
6331 * values.c (baseclass_addr): Run loop from INDEX+1 to
6332 N_BASECLASSES; otherwise, we can still get into a loop.
6333 @@ This should be restructured to use a cleaner search strategy.
6335 Sun Jul 1 12:28:51 1990 Michael Tiemann (tiemann at masham)
6337 * dbxread.c (define_symbol,read_type): Grok GNU C++'s new
6338 abbreviation "Tt" for tags which have the same name as their
6341 Fri Jun 29 01:03:46 1990 Michael Tiemann (tiemann at masham)
6343 * symtab.c (list_symbols): add ability to set breakpoints on all
6344 the functions which match a particular regular expression.
6346 Tue Jun 26 04:26:29 1990 Michael Tiemann (tiemann at masham)
6348 * cplus-dem.c (cplus_demangle): New parameter ANSI says whether we
6349 should print ANSI qualifiers (such as `const' and `volatile').
6350 All callers changed to call with ANSI == 1, except from
6351 `check_method_stub', which uses old-style syntax.
6353 * symseg.h (struct fn_field): Remove unneccessary `args' field.
6354 * symtab.h (TYPE_FN_FIELD_ARGS): Redefined.
6356 * values.c (check_stub_method): New function.
6358 * cplus-dem.c (do_type): Handle "long long" (encoded as 'x').
6360 * dbxread.c (read_type): Handle new GNU C++ method type stubs.
6361 * valprint (type_print_base): Ditto.
6363 * symtab.c (gdb_mangle_typename): New function.
6365 Tue Jun 5 00:18:43 1990 Michael Tiemann (tiemann at gzilla)
6367 * breakpoint.c (catch_command): New function. Provides a
6368 mechanism to set breakpoints based on catch clauses.
6369 (disable_catch): Similar, but disables breakpoints on catch
6371 (delete_catch): Similar, but deleted breakpoints on catch clauses.
6373 Sun Jun 3 22:54:08 1990 Michael Tiemann (tiemann at gzilla)
6375 * blockframe.c (blockvector_for_pc): New function.
6376 * blockframe.c (block_for_pc): Changed to call
6377 `blockvector_for_pc' and get the block itself.
6379 * stack.c (catch_info): New function. Prints info about
6380 exceptions which can be caught in the current frame.
6381 * stack.c (print_frame_label_vars): New function. Similar to
6382 `print_frame_local_vars'.
6383 * stack.c (print_block_frame_labels): Prints out labels that are
6384 defined in this frame. These labels are exceptions that can be
6387 * dbxread.c: Updated to handle N_CATCH symtab types.
6389 Thu May 3 22:10:00 1990 Michael Tiemann (tiemann at teacake)
6391 * valprint.c (everywhere): TYPE_NAME (TYPE) no longer comes in the
6392 form "struct ..." for GNU C++. Don't flush any part of TYPE_NAME
6393 when printing the type.
6395 Wed May 2 22:43:04 1990 Michael Tiemann (tiemann at teacake)
6397 * valprint.c (val_print): Use `baseclass_addr' to access the
6398 baseclasses pointed to via the derived class object at VALADDR.
6400 * values.c (baseclass_addr): New function. Casts derived pointers
