1 Thu Nov 21 23:48:56 1991 John Gilmore (gnu at cygnus.com)
3 * Makefile.in: Roll new files into various lists.
5 Thu Nov 21 18:26:11 1991 Fred Fish (fnf at cygnus.com)
7 * dwarfread.c (struct_type): Must initialize the c++ specific
8 portion of union types as well as struct types, since gdb attempts
9 to reference the c++ specific info for both types.
11 Thu Nov 21 10:23:52 1991 John Gilmore (gnu at cygnus.com)
13 * Makefile.in: Roll VERSION to 4.2.90.
15 * defs.h: Incorporate param.h into defs.h. All users changed.
16 * param-no-tm.h: Change users to define TM_FILE_OVERRIDE instead.
17 * param.h, param-no-tm.h: Removed.
18 * Update copyrights in all changed files.
19 * dbxread.c, dwarfread.c, inflow.c, infrun.c, m2-exp.y, putenv.c,
20 solib.c, symtab.h, tm-umax.h, valprint.c: Lint.
21 * tm-convex.h, tm-hp300hpux.h, tm-merlin.h, tm-sparc.h,
22 xm-merlin.h: Avoid host include files in target descriptions.
23 * getpagesize.h: Removed, libiberty copes now.
24 * Makefile.in: Remove getpagesize.h, param.h, param-no-tm.h.
26 * exec.c (exec_files_info): If `verbose' is set, show file offset
29 * main.c: Use getcwd rather than getwd.
30 * standalone.c: Fake getcwd rather than getwd.
31 * xm-*.h: Remove fake values of MAXPATHLEN.
33 * xcoffexec.c: Add /* */ to #if 0'd thing to help ANSI.
35 Wed Nov 20 18:35:56 1991 John Gilmore (gnu at cygnus.com)
37 * Remove gdb/hp-include. Support for HP a.out oddities should be
38 in BFD, not in GDB. Move gdb/hp-include/a.out.h to include/a.out.hp.h.
40 * infptrace.c, tm-sun386.h: Cashier <a.out.gnu.h>, remove refs.
42 * configure.in, xconfig, tconfig, Makefile.in, doc/gdbint.texinfo:
43 Makefile fragments for various hosts and targets now come from
44 gdb/config/mh-* and gdb/config/mt-*. This is for consistency with
47 * rs6000-pinsn.c, rs6k-opcode.h: Clean up.
48 * rs6k-opcode.def: Delete.
50 Wed Nov 20 05:04:40 1991 Fred Fish (fnf at cygnus.com)
52 * dwarfread.c: Recognize obsolete form of AT_element_list
53 attribute still used by at least one AT&T compiler, and possibly
56 Tue Nov 19 07:53:55 1991 Fred Fish (fnf at cygnus.com)
58 * dwarfread.c (enum_type, struct_type): Ignore names invented by
59 helpful compilers for anonymous structs, unions, and enums.
61 * c-exp.y, m2-exp.y: Add defines for yymaxdepth, yy_yys, and
62 yy_yyv, so multiple parsers produced by SVR4 versions of yacc
63 can coexist in the same executable without collision.
65 * symtab.h: Add declaration for lookup_template_type() to kill
66 compiler warnings about conversions from int to pointer.
68 Mon Nov 18 17:45:18 1991 Fred Fish (fnf at cygnus.com)
70 * procfs.c: Move inclusion of defs.h to before param.h, as in
71 all the other source files that include both. This is required
72 to supply some typedefs that are used in files included by param.h.
74 * m68k-tdep.c (m68k_skip_prologue): Add generic m68k support for
75 skipping function prologues, ala the other cpu families (i386,
76 mips, m88k, etc). Add the ability to skip movm and fmovm
77 instructions in the prologues. Still needs support for profile
78 (-p compiled) prologue sequences (FIXME).
80 * tm-68k.h: Change SKIP_PROLOGUE macro to use the new generic
81 m68k prologue skipping function by default.
83 * tm-altos.h, tm-isi.h: Continue to use the old definition of
86 Mon Nov 18 15:12:45 1991 John Gilmore (gnu at cygnus.com)
88 * Makefile.in: Remove tdesc stuff, and extra blanks before colons.
89 * blockframe.c: Remove tdesc-related code. Default
91 * infrun.c: Remove tdesc-related code.
92 * m88k-tdep.c (frame_chain_combine, init_frame_pc): Remove copies
93 of defaultable things.
94 * tm-m88k.h: New file, common to all Moto 88k target configs.
95 Derived from tm-delta88.h.
96 * tm-delta88.h: Use it.
97 * xm-m88k.h: Common file for 88K hosts. Remove obsolete stuff.
98 * xm-delta88.h: Use it.
99 * tm-*.h: Remove FRAME_CHAIN_COMBINE macros, since all are
101 * coffread.c: Remove tdesc stuff.
102 * tconfig/delta88, tconfig/m88k: Remove tdesc stuff.
103 * xconfig/m88k: Rename tm-88k.h to tm-m88k.h.
105 Mon Nov 18 13:51:37 1991 Per Bothner (bothner at cygnus.com)
107 * source.c (open_source_file): If openp fails, try again
108 using just the base (non-directory) part of the filename.
109 This solves various annoying problems, such as when the
110 source was compiled with an absolute pathname - and the
111 source files have moved. Or if the source was compiled
112 using a relative pathname, it can be more convenient
113 to just specific the source directory to the dir command.
115 Mon Nov 18 00:04:41 1991 Fred Fish (fnf at cygnus.com)
117 * cplus-dem.c (munge_function_name): Add missing third arg to
118 instance of call to do_type().
120 * dwarfread.c: Changes to match new dwarf.h. Remove
121 AT_deriv_list, AT_loclist, AT_incomplete, AT_const_data,
124 Sun Nov 17 16:20:53 1991 Michael Tiemann (tiemann at rtl.cygnus.com)
126 * symtab.h (struct type): Moved C++-specific fields into new type
127 `struct cplus_struct_type'. Now takes 10% less memory. Many
129 * symtab.c (init_type): Don't set fields belonging to
130 TYPE_CPLUS_SPECIFIC unless TYPE is TYPE_CODE_STRUCT.
131 * buildsym.c (read_type): Allocate TYPE_CPLUS_SPECIFIC for
133 (read_struct_type): Ditto. Also, add comments about how we can
134 deduce TYPE_VPTR_FIELDNO from inheritance info and fieldname info.
135 * coffread.c (decode_base_type): Allocate TYPE_CPLUS_SPECIFIC for
137 (read_struct_type): Ditto.
138 * dwarfread.c (struct_type): Ditto.
140 * symtab.c (read_range_type): Don't set TYPE_MAIN_VARIANT.
141 (lookup_pointer_type): Don't use or set TYPE_MAIN_VARIANT.
142 (lookup_reference_type): Ditto.
144 * cplus-dem.c: Many changes made to handle decoding of
146 * symtab.c (gdb_mangle_name): Mangle/demangle ANSI-mangled names

151 * mipsread.c (parse_partial_symbols): patch to keep DEC C
152 compiler from making gdb bomb out. Thanks to Ed Santiago!
154 Thu Nov 14 19:27:30 1991 Fred Fish (fnf at cygnus.com)
156 * symfile.c: Add function compact_misc_function_vector() to
157 remove duplicate misc function vector entries. See comments
158 in source for why this is necessary/desirable.
160 * dwarfread.c: Add misc function type parameter to internal
161 record_misc_function(). Remove calls to init_misc_bunches()
162 and condense_misc_bunches(), these are now done in elfread.c.
164 * elfread.c: Add support for reading bfd canonical symbol tables
165 and generating misc function vector entries for global and
166 absolute symbols. Do calls to init_misc_bunches() and
167 condense_misc_bunches() where they will enclose all calls to
168 record_misc_function(), including those in dwarfread.c.
170 Thu Nov 14 17:02:11 1991 Roland H. Pesch (pesch at cygnus.com)
172 * doc/Makefile.in: new targets gdb.me, gdb.ms, gdb.mm
173 (roffable documentation).
174 * doc/gdb.texinfo: embedded hints (as comments) for better
175 texi2roff conversion.
177 Thu Nov 14 13:18:25 1991 John Gilmore (gnu at cygnus.com)

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

315 * dbxread.c: Make more errors into complaints.
316 (push_subfile, pop_subfile): Move to buildsym.c.
317 (dbx_symfile_read, dbx_symfile_init, fill_symbuf, read_dbx_symtab,
318 start_psymtab, psymtab_to_symtab_1, read_ofile_symtab,
319 dbx_psymtab_to_symtab, ): Use bfd ops, don't use file descriptor.
320 Pass objfile. Change callers.
321 (fill_symbuf, SWAP_SYMBOL): Take bfd as arg.
322 (read_dbx_symtab): Just wipe out new symbols, not all, on error.
323 (end_psymtab): Blow away psymtab if empty.
324 (process_symbol_pair): Swallow into read_ofile_symtab.
325 (process_one_symbol): Use push_context and pop_context.
326 (virtual_context): Delete #if 0'd obsolete stuff.
328 * buildsym.c (end_symtab): Pass objfile.
329 (dbx_lookup_type): Handle null typevector.
330 (dbx_alloc_type): Check file number, not sym number, for -1.
331 (find_symbol_in_list): Add for xcoffread.
332 (start_symtab): Default typevector is empty. Keep reusing same
334 (end_symtab): Take objfile argument and pass it to
335 allocate_symtab. Don't make a symtab if no blocks or symbols.
336 Handle empty typevector.
337 (push_context): New function for context stack nesting.
338 (read_type): Mark FIXME where we need to reintroduce type smashing.
340 * buildsym.h (pop_context): Macro, paired with push_context.
341 (subfile_stack): Move here from dbxread.c.
343 * coffread.c (end_symtab, read_coff_symtab): Take and use objfile arg.
344 (read_coff_symtab): Cleanup by freeing objfile, not all symtabs.
346 * mipsread.c (read_mips_symtab, parse_partial_symbols, parse_fdr,
347 new_psymtab, new_symtab): Take and use objfile arg.
349 * dwarfread.c (scan_compilation_units, start_psymtab,
350 process_dies, end_symtab, dwarf_build_psymtabs,
351 read_lexical_block_scope, read_func_scope, read_file_scope): Take
352 and use objfile argument.
353 (psymtab_to_symtab_1, read_ofile_symtab): Don't take or use file
354 descriptor. Use BFD internal functions instead.
355 (end_symtab): Call global allocate_symtab.
357 * elfread.c, target.c: Minor changes to accommodate objfiles.
358 * symtab.h: partial_symbol_table has no symfile_name member now.
359 (fn_fieldlists voffset): avoid non-int bitfield.
360 (struct symtab): Add objfile * and objfile_chain * of symtabs.
361 (struct partial_symtab): Add objfile * and objfile_chain * of
362 psymtabs. Remove symfile_name.
364 * symmisc.c: Lose free_all_symtabs, free_all_psymtabs.
365 (printsyms_command): Rename from print_symtabs. Add selective
366 listing if 2nd argument given. Print objfile info.
367 (printpsyms_command): Rename from print_partial_symtabs. Ditto all.
368 (printobjfiles_command): New; prints objfiles lists, and checks
369 for consistency of symtab, psymtab, and objfile lists.
371 * symfile.h, symfile.c, symtab.h: Lint
373 Fri Nov 8 23:38:48 1991 John Gilmore (gnu at cygnus.com)
375 * command.c: Include param.h.
376 * defs.h (warning_setup, warning): Declare.

378 * inflow.c (new_tty): Use USE_O_NOCTTY #define.
379 * language.c, printcmd.c (print_scalar_formatted), signame.c,
382 Thu Nov 7 18:26:15 1991 Steve Chamberlain (sac at rtl.cygnus.com)
384 * Makefile.in: link with libiberty after libreadline, since
385 readline might want something in libiberty.
386 * m88k-xdep.c: Fixed the register offsets in the ptrace_user
387 struct for BCS 88k machines.
388 * xm-m88k.h: don't define USIZE if already defined.
389 * configure.in: Added delta88 target.
391 Thu Nov 7 04:51:19 1991 John Gilmore (gnu at cygnus.com)
393 * am29k-pinsn.c, am29k-opcode.h: Fix decoding of mtacc, dmac, fmac.
395 * tm-*.h: Remove READ_DBX_FORMAT, COFF_FORMAT, and
396 READ_MIPS_FORMAT, which have been unused since BFD. Still
397 remaining is COFF_NO_LONG_FILE_NAMES.
398 * tm-sun3.h, tm-altos.h: Remove detritus accidentally left from
399 function calling code moved to m68k-tdep.c.
401 Wed Nov 6 17:21:59 1991 John Gilmore (gnu at cygnus.com)
403 * coffread.c: Eliminate c_nsyms in favor of c_naux.
404 Complain if no auxents on .bf and .ef FCN symbols, and assume
405 lots of line numbers.
406 (init_linenos, enter_linenos): Use a sentinel at the end of the
407 read-in linenos, to make for a fast, safe loop-end test.
409 Wed Nov 6 02:54:08 1991 Steve Chamberlain (sac at cygnus.com)
411 * coffread.c (read_coff_symtab): coffread used to rely on the
412 x_sym.x_misc.x_lnsz.x_lnno field giving the # of linnos in a
413 function. Two of the formats I'm using (29k and 88k) don't seem to
414 set it. Ths patch to fcn_last_line and (enter_linenos) is an
415 attempt to use the actual size of the linno table in the file to set
416 the number of linenos to process.
418 Tue Nov 5 22:47:46 1991 Steve Chamberlain (sac at cygnus.com)
420 * Makefile.in: put a - infront of the mv y.tab.c c-exp.tab.c and
421 mv y.tab.c m2-exp.tab.c, so that if bison is used, and the files
422 are created in place, so the mv fails, then the make continues.
424 Tue Nov 5 16:47:47 1991 Per Bothner (bothner at cygnus.com)
426 Add C++ as a separate language.
427 * defs.h (enum language): Add language_cplus.
428 * dwarfread.c (end_symtab): Support language_cplus.
429 * c-exp.y: Add new struct language_defn cplus_language_defn.
430 Don't set c to be the default language (see main.c).
431 * c-exp.y (yylex): Only look for field of this if
432 language is C++. (First difference from C!)
433 * language.c: Add case branches for C++ (currently, all
434 the same as C). Also, add c++ to "usage" note for "set lang".
435 * valprint.c (typedef_print). Add case branches for C++.
436 * main.c (main): New way to set initial language: Look at
437 file extension of psymtab containing main(). (Same as we
438 do for symtabs, but avoid loading the symtab yet.)
439 * symtab.c: New routine find_main_psymtab(), used by main()
440 to set initial language.
441 * symfile.c (allocate_symtab): Move code for mapping file
442 extensions-> languages to new deduce_language_from_filename().
444 Fix a C++ problem when looking for methods in super-classes.
445 There was confusion between base and derived types.
446 * valops.c (value_fn_field): Change function interface.
447 * values.c: Use new value_fn_field interface.
449 Mon Nov 4 10:49:33 1991 Per Bothner (bothner at cygnus.com)
451 * infrun.c: Fixed typo in comment.
452 * utils.c: All the v*fprintf emulation is now in libiberty,
453 so we can get rid of some junk.
454 * xm-sun3os4.h, xm-sun4os4.h, xconfig/decstation, xconfig/i386sco,
455 xconfig/sun3os4, xconfig/sun4os4: Don`t need HAVE_STRSTR any more.
456 * m68k-pinsn.c (print_insn_arg): Support BB/BW/BL
457 type operands, as used by branch instructions.
458 * gmalloc.c: Fix prototype of memcpy.
459 * elfread.c: Comment out register_addr, since it conflicts
460 with the one in coredep.c.
461 * buildsym.h: Remove extern declarations of two functions
462 that are really static in buildsym.c.
463 * tm-mips.h: Add symbolic names for more registers.
464 * mips-xdep.c (store_inferior_registers): Use new register names.
465 * xm-mips.h: Simplify REGISTER_U_ADDR, since it is now
466 only used for core files, not ptrace. Therefore,
467 the KERNEL_U_ADDR hack is no longer needed.
468 The mapping to ptrace number is now in in mips-xdep.c.
469 * mips-xdep.c: Define REGISTER_PTRACE_ADDR (using the
470 mapping from the old REGISTER_U_ADDR), and use it
471 in {fetch,store}_inferior_registers.
472 * mipsread.c: Rename #include ecoff.h to new name coff-mips.h.
473 * mips-tdep.c (mips_push_dummy_frame, mips_pop_frame):
474 Save/restore FP regs correctly (?).
475 * dbxread.c: Remove duplicate define_symbol and type_synonym_name
476 (these had been previously moved to buildsym.c).
477 Hence, define_symbol becomes extern instead of static.
478 * buildsym.c (read_struct_type): Comment out bogus handling
479 of C++ operator methods. Minor hacking of reading of class
480 contexts. Make define_symbol non-static, so dbxread.c can call it.
482 Fri Nov 1 11:05:47 1991 John Gilmore (gnu at cygnus.com)
484 * mipsread.c (read_mips_symtab, read_the_mips_symtab): Use real
485 filename with error messages.
486 * stack.c (frame_select_command): Rename to select_frame_command
487 to avoid "fr" and "fra" having nonunique completions.
488 * symfile.c (sort_symtab_syms): Ignore sort of zero symtab *.
489 (symfile_init): Print file format name when unable to handle it.
490 (free_named_symtabs): Use BLOCKVECTOR rather than obsolete BLOCKLIST.
491 * symmisc.c (free_symtab): Only free linetable if nonzero.
492 * symtab.h: Remove obsolete BLOCKLIST macros.
494 Thu Oct 31 18:12:43 1991 Stu Grossman (grossman at cygnus.com)
496 * infrun.c (wait_for_inferior): another stepi/nexti fix. Ensure
497 that stop_step is 1 at bottom of main loop. I don't know why this
498 needs to be done, but it helps me sleep better at night.
500 Sun Oct 27 18:18:39 1991 Stu Grossman (grossman at cygnus.com)
502 * main.c (initialize_history): Read history after reading all
505 Sun Oct 27 14:09:25 1991 John Gilmore (gnu at cygnus.com)
507 * buildsym.c: Break out initial malloc sizes.
508 (record_line): Record directly in a subfile. Alloc on demand.
509 (compare_line_numbers): Add from xcoffread.c.
510 (end_symtab): New params say whether to sort pendings and
511 linetable. Patch block stabs if defined. Shrink linetable before
512 allocating the symtab.
513 * buildsym.h: Delete line_vector* and prev_line_number. Add
514 global_stabs and file_stabs for xcoffread.
515 * dbxread.c (start_subfile): Move to buildsym. Change above calls.
516 * symtab.h: LINETABLE(symtab) can now be null. Zap LINELIST.
517 * symmisc.c, symtab.c: Cope with null LINETABLEs.
519 * blockframe.c: Pass fromleaf to INIT_EXTRA_FRAME_INFO.
520 * tm-29k.h, tm-88k.h, tm-i960.h, tm-irix3.h, tm-mips.h, tm-pyr.h,
521 tm-sparc.h: Accept fromleaf parameter.
522 * c-exp.y (yyerror): Pass error message if given.
523 * configure.in: Add rs6000 host and target.
524 * inflow.c (new_tty): O_NOCTTY kludge for RS/6000.
525 * symfile.h (entry_point): Add.
527 Sat Oct 26 00:16:32 1991 John Gilmore (gnu at cygus.com)
529 * buildsym.c: New file. Breaks out symbol-table-building routines
530 from dbxread.c, so they can be shared with xcoffread.c.
531 * buildsym.h: New file. Declarations for buildsym.c users.
532 * dbxread.c: Remove large chunks into buildsym.c.
533 * Makefile.in: Add buildsym.c and buildsym.h.
535 * symfile.c (syms_from_bfd): New routine.
536 (add_symbol_file): Call it to do the real work.
537 (syms_from_bfd): Initialize entry_point before calling symfile_init.
538 * symtab.h, symfile.c, coffread.c, mipsread.c, dwarfread.c:
539 Avoid declaring or setting entry_point (symfile.h & symfile.c cope).
541 Fri Oct 25 10:58:16 1991 Mark Eichin (eichin at cygnus.com)
543 * cplus-dem.c (cplus-demangle): added support for templates, static
544 data, and the new (correct) mangling for destructors.
546 * dwarfread.c: (dwarfwarn): created a varargs version of
547 dwarfwarn, for non __STDC__ compilers.
549 * c-exp.y: (yylex): added match for "template" token.
550 (typebase): added TEMPLATE name '<' type '>' clause, for explicit
551 specification of template types.
553 * symtab.c: (lookup_template_type): new function for finding
554 templates in symbol table.
555 (type_name_no_tag): changed to explicitly check for s/u/e at the
556 beginning of the symbol - if it is a template, none of these will
557 be there (but the name will still contain spaces.)
559 Fri Oct 25 18:59:32 1991 Per Bothner (bothner at cygnus.com)
561 Various fixes to improve g++ debugging.
562 * symtab.h: Add is_const and is_volatile flags for each method.
563 These are bit fields - take their space from voffset,
564 which shrinks to 30 bits. Since voffset is now a bitfield,
565 make it unsigned for portability. This changes its interpretation
566 slightly: Static methods now have voffset 1 instead of -1,
567 and virtual offsets start at 2, not 1.
568 * symtab.c: Renamed gdb_mangle_typename to gdb_mangle_name,
569 since it now returns an entire magled method name, not just
570 the type part. This avoids some duplication.
571 It also allows us to correctly mangle const and volatile
572 methods (using the new is_const and is_volatile bit fields
574 * valprint.c (type_print_base), values.c (check_stub_method):
575 Simplify by using new gdb_mangle_name.
576 * values.c (value_headof): Fix to correctly handle single
577 inheritance (actually two fixes, either of which suffices).
578 * dbxread.c (read_struct_type): Handle const and volatile
580 * dbxread.c (read_struct_type): Yet one more place where
581 we must handle '\\' continuations.
582 * valprint.c (vtbl_ptr_name): Add final '\0'.
584 Fri Oct 25 16:06:38 1991 Stu Grossman (grossman at cygnus.com)
586 * tm-sparc.h, tm-68k.h (EXTRACT_RETURN_VALUE): fix output of
587 short return values for sparc and 68k. Patch from Paul Eggert.
589 * coffread.c, coredep.c, i386-xdep.c: install patches for
590 SysV/386 3.2 from Mauro DePalma.
592 Fri Oct 25 02:02:13 1991 John Gilmore (gnu at cygnus.com)
594 * core.c (core_file_info), exec.c (exec_file_info): Print file
595 type. Use printf_filtered.
597 * valops.c (value_fetch_lazy): Avoid 0-length fetches.
599 Thu Oct 24 23:06:40 1991 Fred Fish (fnf at cygnus.com)
601 * dwarfread.c: Add casts to remove compiler warnings.
603 * tm-3b1.h, tm-68k.h, tm-altos.h, tm-amix.h, tm-hp300bsd.h,
604 tm-hp300hpux.h, tm-isi.h, tm-news.h, tm-pn.h, tm-sun2.h,
605 tm-sun3.h: Remove locally duplicated code for calling functions
606 in the inferior. The only differences were in the specific trap
607 vectors used and whether or not an fpu was present. These are
608 now handled by appropriate definitions of BPT_VECTOR and
609 HAVE_68881 respectively. Other minor obvious cleanups.
611 * valops.c: Correct a minor misspelling.
613 * utils.c: Remove local BSD/USG hacks that are now in libiberty.
615 * dwarfread.c: Remove prototype for dwarfwarn. Does not work
618 Thu Oct 24 09:33:44 1991 John Gilmore (gnu at cygnus.com)
620 * stack.c (frame_command): Always print. Use new
621 frame_select_command to select a frame without printing.
623 * dwarfread.c: Use <varargs.h>, since <stdarg.h> is not portable.
625 Thu Oct 24 01:32:51 1991 Fred Fish (fnf at cygnus.com)
627 * dwarfread.c: New file for DWARF debugging format support.
629 * elfread.c: New file for ELF object file format support.
631 * procfs.c: New file for SVR4 /proc (process file system) support.
633 * tm-amix.h, xm-amix.h, tconfig/amix, xconfig/amix: New files for
636 * xm-svr4.h, tm-svr4.h: New files for SVR4 support.
638 * xm-m68k.h: New file for host machines with m68k cpu.
640 * Makefile.in: Add elfread.c and dwarfread.c to SFILES_MAINDIR.
641 Add elfread.o and dwarfread.o to OBS.
643 * symfile.h: Add "elf" to list of supported formats in comment.
645 * c-exp.y, defs.h, symtab.h, valprint.c: Add three new builtin
646 types to gdb, builtin_type_long_double, builtin_type_complex, and
647 builtin_type_double_complex. Add and use new TARGET_SHORT_BIT,
648 TARGET_INT_BIT, TARGET_LONG_BIT, TARGET_FLOAT_BIT,
649 TARGET_DOUBLE_BIT, TARGET_LONG_DOUBLE_BIT, TARGET_COMPLEX_BIT, and
650 TARGET_DOUBLE_COMPLEX_BIT, as the sizes in bits of the indicated
651 types on the target machine (ala the existing TARGET_LONG_LONG_BIT).
653 * infrun.c: When using SVR4 /proc interface instead of ptrace(),
654 call proc_set_exec_trap() to setup child to stop at first instruction.
656 * inftarg.c: When using SVR4 /proc interface, call proc_wait()
659 * m68k-tdep.c: Add new routines supply_gregset(), fill_gregset(),
660 supply_fpregset(), and fill_fpregset(), which are machine
661 dependent support routines for SVR4 /proc interface.
663 * utils.c: Add warning_setup() and warning(). Warning() behaves
664 the same as error() except that it returns normally rather than
665 jumping back to command level. Modules that don't want to call
666 warning() for some reason, but want to produce their own warnings,
667 can call warning_setup() to ensure compatibility with the way
668 warning() and error() deal with the terminal.
670 * symtab.c: Make internal errors produce more useful messages.
672 * tm-68k.h: Move code that is duplicated in almost every single
673 m68k based machine's configuration files to this common file.
674 Duplications in the configuration files still need to be removed
677 * infrun.c (child_create_inferior): System V versions must call
678 setpgrp() with no arguments, to comply with prototyping typically
681 * munch: Add support for SVR4 style nm output.
683 * dbxread.c, mipsread.c symmisc.c, symtab.c: Remove the object
684 file specific fields from the partial symbol table structure and
685 replace them with a pointer to private data for each different
686 flavor of object file reader to initialize appropriately.
688 Wed Oct 23 09:38:20 1991 John Gilmore (gnu at cygnus.com)
690 * xconfig/sun[34]os4: Add note about strstr botch on sunos4.0.3c
693 * mipsread.c (fixup_undef_type): New function. If a struct /
694 union / enum is defined in a header file but nowhere else used,
695 (by typedefing, pointer referencing or declaration) the mipsread code
696 builds the complete tree for the structure but leaves its code as
697 TYPE_CODE_UNDEF as it doesn't know what kind of aggregate it is.
698 Guess its type based on the details of the members.
700 Tue Oct 22 18:04:32 1991 Stu Grossman (grossman at cygnus.com)
702 * infrun.c (wait_for_inferior): Check return value from
705 Mon Oct 21 17:47:03 1991 Stu Grossman (grossman at cygnus.com)
707 * infrun.c (wait_for_inferior): fix stepi/nexti that was broken
708 by my last edit to this routine.
710 Mon Oct 21 14:27:43 1991 John Gilmore (gnu at cygnus.com)
712 * tm-sun3.h (FIX_CALL_DUMMY): problem with cross debugging.
713 FIX_CALL_DUMMY does unaligned accesses and/or forgets to byte swap
714 the values before putting them into the dummy code. (From Peter
717 Mon Oct 21 10:04:39 1991 Steve Chamberlain (steve at rtl.cygnus.com)
719 * configure.in: added ebmon target.
721 Wed Oct 16 22:49:58 1991 John Gilmore (gnu at cygnus.com)
725 * Makefile.in: Roll VERSION to 4.2.
726 * README, TODO, WHATS.NEW: Update.
728 * core.c (core_open): Improve error message for bad file.
729 Pass .reg virtual memory address to fetch_core_registers to help
730 it find the registers in the core-file header.
731 * coredep.c (fetch_core_registers): Take new argument, use it,
732 and pass it to register_addr to locate the block of registers.
733 * xm-mips.h: Update KERNEL_U_ADDR for new scheme. Cleanup a bit.
735 * dbxread.c (read_dbx_symtab, process_one_symbol): Handle
736 Sequent N_FN_SEQ like everybody else's N_FN.
738 * main.c: Circumvent SCO cc bug with #if !!defined(USG).
739 * tm-i386v.h: #endif guck.
740 * xconfig/i386*: Remove -Dgetpagesize()=4096 kludge.
741 * xconfig/i386sco: Add HAVE_STRSTR to avoid ANSI bdeath.
742 * xconfig/tahoe: Add REGEX, which seems to be missing.
744 * coredep.c: Add <sys/types.h> for SCOnix.
745 * dbxread.c (read_dbx_symntab): Avoid coredump on malformed file.
746 * printcmd.c (print_formatted): Flush output before disassembly.
748 Tue Oct 15 20:12:32 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
750 * doc/refcard.tex (sec "Working Files"): consistent metavars and
751 other improvements, due to comments by François Pinard
752 (pinard@iro.umontreal.ca)
754 * doc/gdb.texinfo (appendix "Installing GDB"): changes in
755 configure, and improvenets related to Pinard's refcard comments
757 Tue Oct 15 08:45:12 1991 John Gilmore (gnu at cygnus.com)
759 Changes from Fred Fish:
760 * tm-68k.h (FPI_REGNUM): Add.
761 * infrun.c (child_create_inferior): flush stdout and stderr
763 * configure.in: Handle amigados, amix hosts and targets.
764 * inflow.c: Handle TIOCGLTC_BROKEN for Amiga.
767 * values.c (show_convenience): Use printf_filtered.
768 * main.c (define_command): Check result of lookup_command for
770 (echo_command): Use printf_filtered, and force output out.
772 * dbxread.c (read_enum_type): Avoid Modula-2 kludge that breaks C
774 * i387-tdep.c (double_to_i387): Fix typo for double_to_ieee_extended.
775 * utils.c (_initialize_utils): If !ISATTY, don't paginate.
776 * configure.in, tconfig/decstation, xconfig/decstation: Rename
777 dec3100 to decstation.
779 Mon Oct 14 13:37:50 1991 Roland H. Pesch (pesch at cygnus.com)
781 * doc/gdb.texinfo: Catch up to changes recorded here in ChangeLog
782 (nodes Continuing and Stepping; Memory; Targets) clarifications
785 Fri Oct 11 23:27:06 1991 John Gilmore (gnu at cygnus.com)
787 * tm-{irix3,mips,nindy960,pn,symmetry,vx960}.h: Move
788 REGISTER_U_ADDR to corresponding xm- file. Sugg. by Peter Schauer.
790 * symmisc.c (print_partial_symtabs): Add printpsyms debug cmd.
792 * m68k-tdep.c (m68k_push_dummy_frame, m68k_pop_frame): Add
793 generic routines for calling inferior functions.
795 * blockframe.c (inside_main_scope, inside_entry_scope): New.
797 * copying.awk: Filter formfeeds out of copying & warrantee.
798 Make them available as `show copying' and `show warrantee' also.
799 * main.c (print_gnu_advertisement): Advt `show' commands.
801 Thu Oct 10 17:25:47 1991 John Gilmore (gnu at cygnus.com)
803 * mach386-xdep.c: Even when cross-compiling, leave in the
804 core-file reading code.
805 * core.c (get_core_registers): Avoid coredump if no .reg section.
807 Wed Oct 9 17:03:34 1991 John Gilmore (gnu at cygnus.com)
809 * mipsread.c, coffread.c: initialise TYPE_VPTR_FIELDNO to -1.
810 This avoids coredumps under `set print object on' in value_headof
811 (called erroneously by value_from_vtable_info) for `p &struct'
812 or `p *struct'. From Peter Schauer.
814 Mon Oct 7 00:06:52 1991 John Gilmore (gnu at cygnus.com)
816 * Makefile.in: Roll version to 4.1.2.
817 * dbxread.c: Use aout64.h, not a.out.gnu.h. Get external symbol entry
818 size from BFD (but, FIXME, we don't yet read external nlists's and
819 convert them to internal nlists's before handling them -- we still
820 assume they have the same size and alignment.) Use SET_NAMESTRING
822 * exec.c (exec_file_command): Move dead coff-encapsulation code
824 * m88k-tdep.c, m88k-xdep.c: Remove encap test and #inc <a.out.h>.
826 Fri Oct 4 22:30:06 1991 John Gilmore (gnu at cygnus.com)
828 * configure.in, tm-i386v.h, xm-i386v.h: Intel 386 Mach host port.
829 * xm-i386mach.h, mach386-xdep.c, xconfig/i386mach: New files.
831 Fri Oct 4 17:04:31 1991 Per Bothner (bothner at cygnus.com)
833 More patches from Peter Schauer <pes@regent.e-technik.tu-muenchen.de>:
834 * mips-xdep.c (store_inferior_registers): Don't try to
835 write the (pseudo) FP.
836 * mipsread.c (parse_partial_symbols): Improved algorithm for
837 setting pst->texthigh.
839 Fri Oct 4 16:47:32 1991 Roland H. Pesch (pesch at cygnus.com)
841 * doc/Makefile: make TEXINPUTS include . everywhere
843 Fri Oct 4 00:35:56 1991 John Gilmore (gnu at cygnus.com)
845 * coffread.c, dbxread.c, symfile.c, symmisc.c, symtab.h: Remove
846 vestiges of typevectors, which were for symsegs and are no longer
847 used. (From a question by Eliot Dresselhaus
848 <dresselh@RFT30.nas.nasa.gov>).
850 Thu Oct 3 09:33:26 1991 John Gilmore (gnu at cygnus.com)
852 * dbxread.c, coffread.c: static-ize functions that were
853 gratuitiously external. (From Fred Fish.)
855 * c-exp.y: sym->class to SYMBOL_CLASS (sym).
857 * dbxread.c (dbx_lookup_type): Keep doubling size of typevector
858 until it is large enough.
860 * dbxread.c (read_type): Handle error case slightly better.
861 Make complaint message not C++-specific.
863 Wed Oct 2 17:21:07 1991 Stu Grossman (grossman at cygnus.com)
865 * infrun.c (wait_for_inferior): Fix step/next so that you only
866 stop at the beginning of a new line. This fixes various problems
867 with for loops, nested if-else's and switch statements.
869 Tue Oct 1 06:33:55 1991 John Gilmore (gnu at cygnus.com)
871 * symtab.c (lookup_symtab_1, lookup_symbol): "fatal" errors
872 between symtabs and psymtabs become ordinary error()s.
874 * dbxread.c (read_dbx_symtab): Relocate end_of_text_addr
875 properly, making "end pc" correct in shared lib psymtabs.
876 (From Guy Harris <guy@auspex.com>.)
878 Mon Sep 30 13:15:31 1991 John Gilmore (gnu at cygnus.com)
880 * dbxread.c: Enable, but soften, const_vol_complaint.
881 (read_dbx_symtab): N_STSYM and N_LCSYM define static vars.
882 Ditto Gould N_NBSTS and N_NBLCS. Also, all types in the psymtab
883 should be file-scope, not global.
884 (read_struct_type): Remove ancient multiple-inheritance warning.
885 (read_range_type): Check base type, complain & patch if undefined.
886 * stack.c (frame_info): Demangle the function name in `info stack'.
889 Sat Sep 28 10:02:33 1991 John Gilmore (gnu at cygnus.com)
891 * eval.c (evaluate_subexp_for_address): Don't use
892 TYPE_POINTER_TYPE directly (it might be zero if this type has
893 never had a pointer created before); use lookup_pointer_type.
894 * symtab.c (lookup_method_type): Arguments were swapped in all
895 callers, so fix it here. I'm amazed this worked at all!
897 Fri Sep 27 18:09:31 1991 John Gilmore (gnu at cygnus.com)
899 * c-exp.y, m2-exp.y: Define more yysymbols that happen to be
900 "bss" rather than "data" symbols, but which still conflict.
903 * coffread.c (coff_symfile_read): Use xmalloc, not malloc.
904 * core.c (core_files_info): Shorten output.
905 * exec.c (exec_files_info): Ditto.
906 (build_section_table): Ignore zero-length sections.
907 * language.c, printcmd.c: Lint.
908 * language.h (get_frame_language): Declare.
909 * saber.suppress: update.
910 * stack.c (find_relative_frame): Remove complex code that was
911 #if 0'd, stick with simple code. Lint.
912 * saber.suppress: Update a bit.
913 * symfile.c (add_symbol_file_command): Add "?" to question.
914 * utils.c (parse_escape): Avoid \a due to bdead compilers.

917 * valprint.c (val_print, type_print_base): TYPE_CODE_RANGE less
920 * nindy-tdep.c (nindy_frame_chain_valid): Use lookup_misc_func.
921 (Reported by Mark Peek <mark@imagen.com>.)
923 * solib.c (solib_map_sections): Relocate all sections, even
924 though only the text section's size is tracked. Mark ld_text
925 for eventual elimination as we generalize to N sections.
927 * infrun.c (wait_for_inferior): Don't check if the PC is in a
928 call_dummy if we were stopped by a random signal that is being
929 passed to the program. This produced wierd results when calling
930 functions in the inferior and signals (e.g. SIGALRM) were in use.
932 Tue Sep 24 18:05:30 1991 John Gilmore (gnu at cygnus.com)
934 * infrun.c (IN_SIGTRAMP): Not parenthesized properly.
935 Bugfix from Paul Eggert <eggert@twinsun.com>.
936 * tm-ultra3.h (IN_SIGTRAMP): Ditto.
937 * valprint.c (print_floating): Print 9 digits for IEEE floats.
940 Mon Sep 23 15:50:07 1991 John Gilmore (gnu at cygnus.com)
942 * Makefile.in: Roll VERSION to 4.1.1.
943 * source.c (line_info): Peter Schauer fixes a bug I introduced in
946 Fri Sep 20 16:10:52 1991 John Gilmore (gnu at cygnus.com)
950 * Makefile.in (VERSION): Set to 4.1.
951 * language.c (set_language_command): Print useful help message,
952 and restore the language string after giving help.
953 * valprint.c (typedef_print): Print typedef in C or M2.
954 * symtab.c (list_symbols): Use it.
955 * main.c (main): Avoid any output before (gdb) prompt when -q.
956 * language.c (set_language_command): Handle errors by restoring
957 the language string to its current state (fix from A. Beers).
958 * doc/gdbint.texinfo: Roll in information from README. Rearrange
959 "how to install" and "how to print the doc" stuff so it drops
961 * configure.in: Rename rtpc CPU to romp to match config.sub.
962 * README, WHATS.NEW, TODO: Update for gdb-4.1.
964 Fri Sep 20 17:39:14 1991 Roland H. Pesch (pesch at cygnus.com)
966 * doc/gdb.texinfo: Updates from ChangeLog. set/show write,
967 autoloading shared libs, copyright etc on GDB startup, clean up $_
968 and $__ index refs, set/show listsize and related updates to list
969 cmd. New host/target configs.
971 Fri Sep 20 15:46:00 1991 Roland H. Pesch (pesch at cygnus.com)
973 * doc/Makefile: generate aux version-no file doc/gdbVN.m4
974 from main Makefile.in version definition
975 doc/gdb.texinfo: use version recorded in doc/gdbVN.m4 for current
977 Makefile.in (setup-to-dist): generate doc/gdbVN.m4
979 * doc/gdb.texinfo: merge new language-switching and lang-specific
982 Fri Sep 20 15:00:57 1991 Per Bothner (bothner at cygnus.com)
984 * mcheck.c: Add __ONEFILE kludge to allow compilation by non-ANSI
985 compilers (which may lack stddef.h).
987 Fri Sep 20 13:29:42 1991 John Gilmore (gnu at cygnus.com)
989 * dbxread.c (read_dbx_symtab, process_one_symbol): N_FN and
990 N_WARNING are the same except for the N_EXT bit, so just use their
991 values alone, rather than OR-ing them with N_EXT.
993 Fri Sep 20 12:27:55 1991 Stu Grossman (grossman at cygnus.com)
995 * mipsread.c (parse_lines): Deal with negative extended line
998 * c-exp.y, m2-exp.y: #define yyerrflag and yynerrs to avoid
999 global symbol conflicts.
1001 Fri Sep 20 02:28:15 1991 John Gilmore (gnu at cygnus.com)
1003 * .gdbinit: Move 'set complaints' to top, so it runs even in
1004 case we aren't debugging GDB.
1005 * language.c (_initialize_language): Fix type check and range
1006 check documentation strings.
1007 * utils.c (!HAVE_VPRINTF): Define vfprintf as a function, so
1008 language.c can use it. (Though language.c should really not be
1009 handling warnings/errors the way it does, FIXME.)
1010 * symtab.c (lookup_primitive_type): const lint.
1012 Bugfix from Peter Schauer:
1013 * source.c (lines_to_list): Make signed, to avoid comparison
1014 going unsigned and complaining that -3 is too high for 21 lines.
1015 * stack.c (lines_to_list): Ditto.
1017 Thu Sep 19 23:33:41 1991 John Gilmore (gnu at cygnus.com)
1019 * Makefile.in (HFILES): Add minimon.h.
1020 (VERSION): Roll version number to 4.0.95.
1021 (gdb.tar.Z, make-proto-gdb.dir, setup-to-dist, gdb-XXX.tar.Z):
1022 New rules for building distributions. Normal distribution
1023 is built by doing `make -f Makefile.in gdb.tar.Z' in the directory
1024 one level up from here; it calls make-proto-gdb.dir to build a
1025 directory `proto-gdb' which is an image of the release. The old
1026 `gdb.tar.Z' rule still works too.
1027 * config.sub, configure: Roll in latest from ..
1029 Thu Sep 19 17:41:24 1991 Roland H. Pesch (pesch at cygnus.com)
1031 * doc/gdbint.texinfo: Reorder contents; reorganize new-host,
1032 new-target, and new-config chapters; fix minor typos; come closer
1033 to usual GNU markup conventions for @file @samp @code @var.
1035 Thu Sep 19 17:04:12 1991 Per Bothner (bothner at cygnus.com)
1037 Patches from Peter Schauer <pes@regent.e-technik.tu-muenchen.de>:
1038 * mipsread.c (parse_partial_symbols): Enter the name of all
1039 structs/unions... into the psymtab so we can access them if the
1040 symtab is not read in.
1041 * mips-tdep.c: Remove some unneeded #includes.
1042 * xconfig/dec3100: Add HAVE_STRSTR.
1044 Thu Sep 19 15:14:23 1991 John Gilmore (gnu at cygnus.com)
1046 * Makefile.in: Circumvent Sun Make bug on *-exp.tab.o.
1047 * c-exp.y, m2-exp.y: Lint.
1048 * m2-exp.y: Avoid using yytname[] which is a Bison-ism.
1049 * valprint.c (val_print_fields): Check for stub type.
1050 * mipsread.c (_initialize_mipsread): Avoid using
1051 builtin_type_void at initialize time.
1052 (mipscoff_symfile_read): use it now.
1054 Wed Sep 18 15:55:51 1991 John Gilmore (gnu at cygnus.com)
1056 Merge multiple-language support, and partial Modula-2 support,
1057 from Andrew Beers <beers@cs.buffalo.edu>.
1059 * i387-tdep.c: New file, consolidates most 80387 support,
1060 and eliminates host dependency on double<->extended conversions.
1061 * i386-xdep.c, symm-xdep.c: Remove most 387 support.

1079 (process_coff_symbol): #if 0'd for functions and params as above.
1080 (read_enum_type): Recognize Modula-2 BOOLEAN.
1081 * symtab.c (add_param_to_type): #if 0'd function to add a

1088 hex with local_hex_string for Modula-2 support.
1090 * breakpoint.c (breakpoint_cond_eval): Use new value_true to test

1117 TYPE_CODE_BOOL and TYPE_CODE_CHAR.
1119 * expression.h (enum exp_opcode): Add Modula-2 specific opcodes.
1120 * expprint.c: Look up expression opcodes in language-specific

1153 Tue Sep 17 08:37:41 1991 John Gilmore (gnu at cygint.cygnus.com)
1155 Add Andrew Beers' changes for Modula-2 support. His ChangeLog
1156 entries are enclosed herein. Not all of these changes
1157 have been merged into the master GDB sources -- check the
1158 ChangeLog above here for the merge log.
1160 Mon Jun 3 17:05:45 EDT 1991
1162 m2-exp.y Created. Tested outside of GDB for a few days. Proper
1163 operators were added, C specific operators and tokens
1164 removed. yylex() revamped to some extent. Still things
1165 missing from the grammar, such as sets.
1166 Tested for two weeks in GDB v3.5.
1168 Tue Jun 11 17:23:48 EDT 1991
1170 m2-exp.y Added boolean constants TRUE and FALSE to the grammar
1171 so they are built-in. Sort of a hack.
1173 Fri Jun 14 12:53:51 EDT 1991
1175 m2-exp.y Added range checking for numeric constants. Any numeric
1176 constant is assumed to be of builtin type INTEGER unless:
1177 (1) it is octal or hexadecimal, in which case it is a
1178 CARDINAL; (2) it is too big to fit into an INTEGER, in
1179 which case it is a CARDINAL.
1180 eval.c Added simple range checking for +, -, and * on integers.
1181 Doesn't work very well for *, since 6 * 1,000,000,000 =
1182 1,705,032,704, which fails the simple test of result >=
1183 first_operand, no matter in what order the operands are.
1185 Tue Jun 18 14:11:30 EDT 1991
1187 Broke the parser into parts, one containing the C grammar and the other
1188 containing code to be shared by all of the grammars.
1190 The following files no longer exist:
1195 The following files were added:
1197 c-exp.y (The C grammar)
1198 m2-exp.y (The Modula-2 grammar)
1199 parser-code.c (Code that is shared by the above grammar)
1203 Makefile.dist Changed to reflect the above dependencies. NOTE: It is
1204 now necessary to use the Bison compiler compiler, since it
1205 will generate function/variable prefixes other than yy.
1207 Tue Jun 18 16:47:49 EDT 1991
1209 symtab.[ch] Added the external variable working_lang, than holds the
1210 value of the current working language.
1211 Added the ennumerated type language_mode, with the values
1212 language_auto and language_manual, the former meaning that
1213 GDB sets working_lang as needed, and the latter meaning
1214 that the value of working_lang is totally under user
1216 symtab.[ch] Added the Modula-2 pervasive types INTEGER, CARDINAL,
1217 REAL, BOOLEAN and CHAR. Also added the type codes
1218 TYPE_CODE_BOOL and TYPE_CODE_CHAR.
1219 utils.c Added set_language_command and show_language_command to
1220 implement the GDB support commands "set language" and
1222 expression.h A number of identifiers were added to the type exp_opcode
1223 to facilitate Modula-2 builtin functions, integer
1224 division, and array indexing.
1226 Wed Jun 19 13:25:58 EDT 1991
1228 language.h Added the macro STRICT_TYPE, which evaluates to non-zero
1229 if the language specified by working_lang requires the use
1230 of strict typing of expressions. Eventually, even this
1231 will be able to be changed by the user.
1232 Added the macro RANGE_CHECK, which evaluates to non-zero
1233 if the language specified by working_lang requires the
1234 checking of a value against the domain of its type.
1235 Eventually, even this will be able to be changed by the
1237 language.[ch] Predicates involving types (simple_type, ordered_type,
1238 same_type, integral_type, numeric_type, character_type,
1239 boolean_type, float_type) are added. These predicates are
1240 based on the current value of working_lang, and are handy
1243 Wed Jun 19 15:39:34 EDT 1991
1245 eval.c Added the function type_array_rank which computes the rank
1247 valarith.c Added the funtion value_bool, which when given a integer
1248 value.h value (ie. struct value *) as an argument, it returns a
1249 boolean value (ie. struct value *) true if that integer
1250 is non-zero, and a boolean value false otherwise.
1251 valprint.c Added cases for TYPE_CODE_BOOL, so Modula-2 BOOLEAN values
1252 will print out properly.
1254 Wed Jun 19 16:36:34 EDT 1991
1256 valops.c Added the function value_capitalize, which returns it
1257 value.h argument capitalized if its argument is a lowercase
1258 letter, or the argument unchanged if its argument is not a
1260 valarith.c Added the function range_check_p, which returns non-zero
1261 value.h if its value argument is between the integral bounds upper
1263 Added the function range_check_enum_p, which makes sure
1264 that its value argument is a valid member of the domain of
1266 Added the function range_check_range_p, which makes sure
1267 its value argument lies between the upper and lower bounds
1268 of its type argument, which must be a ranged type.
1269 Added the function check_array_index, which range and type
1270 checks an index of an array.
1271 Added the function value_multi_subscript, which computes
1272 array[idx1,idx2...idxN], given a value array and an array
1273 of values representing indicies.
1274 values.c Changed value_from_long to work with TYPE_CODE_CHAR and
1275 unpack_long to work with TYPE_CODE_BOOL and
1278 Wed Jun 19 18:04:08 EDT 1991
1280 symtab.c Stored pervasive types in a structure and make
1281 lookup_pervasive_type() a lookup function that was based
1282 on working_lang. If lookup_pervasive_type() returned
1283 non-zero, then that value was returned (a fix, since
1284 before it simply wouldn't return the pervasive type.)
1285 language.h Added the macro CAST_IS_CONVERSION, which evaluates to
1286 non-zero if the language specified by working_lang means
1287 "conversion" when it says "cast".
1288 valops.c Added the function value_real_cast(), which performs a
1289 value.h *cast*, not a *conversion*, which is what value_cast()
1290 does when it can. In particular,
1291 value_cast(<float_type>,4) = 4.0, while
1292 value_real_cast(<float_type>,4) = some mess.
1293 eval.c Modula-2 builtin functions implemented: ABS, CAP, CHR,
1294 parser-code.c FLOAT, HIGH, MAX, MIN, ODD, ORD, TRUNC, and VAL.
1295 expression.h Added macros MAX_OF_TYPE and MIN_OF_TYPE to work with MAX
1296 and MIN on integral types. *NOTE*: These are currently
1297 hardcoded to work only if there are 8 bits per storage
1299 eval.c Made logical functions call value_bool to return a
1300 properly typed boolean value, based on working_lang.
1302 Thu Jun 20 11:55:27 EDT 1991
1304 valprint.c Types now print out in a Modula-2 fashion. This works for
1305 the cases when the type is printed out step-by-step, that
1306 is, it doesn't work when the name of a structured type
1307 (which includes the keyword "struct", etc.) is simply
1309 FIXME: Perhaps this is bad. Parts of it seem to kludgey,
1310 since type specifications in C and Modula-2 are very
1311 different. The C printing of a type is very recursive,
1312 whereas in Modula-2 it is generally very simple. C has
1313 type prefixes and suffixes, which have no real analogue in
1314 Modula-2. Maybe type_print() should call a language
1315 specific type printer. This is also advantageous if we
1316 compile GDB to exclude some of the languages. We'll just
1317 leave those functions out.
1319 Thu Jun 20 16:57:10 EDT 1991
1321 dbxread.c When reading the complete symbol table in (via
1322 psymtab_to_symtab()), the number and types of function
1323 arguments are added to a function type. define_symbol()
1324 calls add_param_to_type() to accomplish this.
1325 Assumption: when we come across a function definition
1326 (N_FUN symbol with an 'f' or 'F' in the name), its
1327 arguments will appear before another function definition.
1328 When a function is found, a pointer to its type is placed
1329 in the global in_function_type. Changes that
1330 add_param_to_type() makes are to this global.
1331 valprint.c The type of a function now includes (for Modula-2) the
1332 types of its parameters.
1333 eval.c Type checking and a check for the proper number of
1334 arguments is now done for function calls. Not sure of the
1335 impact this has on C++ member function yet.
1337 Thu Jun 20 19:58:48 EDT 1991
1339 valprint.c Rewrote the type printer. Broke it into two language
1340 specific parts, adding the functions type_print_m2() and
1342 An unfortunate consequence is this: if you debugging a C
1343 program in Modula-2 mode (why?), info types does not work
1344 well with regular expressions, since the types are printed
1345 out in Modula-2 terminology, but stored in C terminology.
1346 language.[ch] Added the functions new_type_last(), type_keyword(), and
1347 type_sep() to aid in the printing of typedefs.
1348 symtab.c Made the printing of typedefs as language independent as
1349 possible through calls to new_type_last(), type_keyword(),
1352 Fri Jun 21 11:50:26 EDT 1991
1354 dbxread.c Check all incoming ennumerated types. If it looks like
1355 Modula-2's BOOLEAN type, then change the type_code of the
1356 type to TYPE_CODE_BOOL so we can process it as a boolean
1358 valprint.c Replaced some of the 0x%x with calls to sprintf and
1359 hexformat() in val_print().
1360 language.[ch] Added the function hex_to_string(), which converts its
1361 integral argument to a hexadecimal number (format is
1362 language based) and returns the result as a string.
1364 Mon Jun 24 12:25:07 EDT 1991
1366 valprint.c Some functions call type_print_1() directly, instead of
1367 value.h using type_print(), so they can specify where (column) to
1368 print things. Since type_print() takes care of language
1369 dependence, that needs to be called first. Added a
1370 parameter depth to type_print() (so it is now like
1371 type_print_1). Changed type_print to type_print_at, and
1372 made type_print a macro that passes a depth argument of
1374 symmisc.c Changed all calls to type_print_1 to calls to
1376 Makefile.dist Made it possible to build GDB for a specific set of
1377 depend languages. Do this by passing a definition for the macro
1378 LANGS to make. LANGS should be a string containing a
1379 space-separated list of language names (ie. LANGS="c m2").
1380 The default is to build all languages. Note that grammar
1381 files must follow the naming convention of <lang>-exp.y.
1382 gdb.lang This holds the current value of the LANGS macro. It is
1383 examined every time make is called, and is updated if
1385 eval.c Added #ifdef _LANG_<lang> to these files.
1386 expread.c Still need to add them to dbxread.c and coffread.c.
1394 Mon Jun 24 16:33:11 EDT 1991
1396 language.[ch] Added the functions hexformat_pre() and
1397 hex_to_string_pre(), which take a prefix argument to
1398 include in the format string. Thus, hexformat_pre("08") will
1399 return "0x08x" (if the working language is language_c).
1400 Made hexformat() and hex_to_string() calls to the above
1401 with "" as the prefix argument.
1403 am29k-pinsn.c, arm-pinsn.c, breakpoint.c, convex-tdep.c, exec.c, core.c,
1404 dbxread.c, i386-pinsn.c, i386-stub.c, i386-xdep.c, i960-pinsn.c,
1405 infcmd.c, inflow.c, m68k-pinsn.c, m68k-stub.c, m88k-pinsn.c,
1406 mips-pinsn.c, mips-tdep.c, ns32k-pinsn.c, printcmd.c, pyr-pinsn.c,
1407 pyr-tdep.c, pyr-xdep.c, remote-vx.c, remote.c, solib.c, source.c,
1408 stack.c, sun386-xdep.c, symfile.c, symm-xdep.c, symmisc.c, tahoe-pinsn.c,
1409 valprint.c, vax-pinsn.c
1411 Changed all occurences of 0x%[0-9]*l*x in printf format strings to
1412 calls to hexformat() and hex_to_string(). Format strings without
1413 the leading "0x" were ignored.
1415 depend Updated to take the above into account.
1418 Tue Jun 25 15:27:18 EDT 1991
1420 symtab.h Added the types range_mode_t, range_check_t, type_mode_t,
1421 and type_check_t to keep track of the current state of
1422 range and type checking.
1423 main.c Added the variables range_mode, range_check, type_mode,
1424 and type_check to record the current state of range and
1425 type checking. Added initialization code to main().
1426 language.h Changed the macros STRICT_TYPE and RANGE_CHECK to examine
1427 the above variables.
1430 Tue Jun 25 17:57:08 EDT 1991
1432 dbxread.c process_one_symbol() updates the variable (enum language)
1433 source_lang based on the extension of the filename
1434 contained in the N_SO sybmol that started this symtab.
1435 When end_symtab() is called, the value of source_lang is
1436 put into the language field.
1437 stack.c select_frame() sets working_lang (and possibly type_check
1438 and range_check) to the language field of the symtab
1439 associated with the frame that is selected if working_mode
1440 is language_auto. If working_mode is language_manual, a
1441 warning is printed and working_lang is not set.
1442 language.c Added the function set_type_range(), which sets the value of
1443 type_check and range_check (if their modes call for
1444 automatic setting) based on the current value of
1445 working_lang. A non-zero argument will cause the current
1446 settings to be output.
1449 Wed Jun 26 14:51:40 EDT 1991
1451 eval.c Added range checks on assignment.
1452 m2-exp.y Added the grammar for sets to the language. Currently,
1453 these do not do anything except print an error message.
1455 Wed Jun 26 17:01:04 EDT 1991
1457 m2-exp.y Added the ability for parse_number() to parse negative
1458 numbers. A global flag is set upon encountering a unary
1459 minus. This was done to make, for example, 1 parse as a
1460 CARDINAL, and not as an integer, per Wirth's examples in
1461 Programming in Modula-2 ed.4.
1462 valprint.c Added support for "set radix 2" by then setting
1463 output_format to 't'.
1464 eval.c Implemented range checking on subrange types. Added calls
1465 to range_check_range_p for BINOP_ASSIGN and BINOP_VAL.
1466 Implemented MIN and MAX for ennumerated types. The
1467 minimum value of an ennumerated type is defined by Wirth
1468 as the first identifier, and the maximum as the last.
1469 m2-exp.y Made octal numbers ending with "B" be characters and those
1470 ending with "C" be numbers, per Wirth's book. (p. 34)
1472 Thu Jun 27 14:11:52 EDT 1991
1474 stack.c select_frame() now only sets working_lang, it does not
1475 notify the user. If working_mode is language_manual, then
1476 a warning is issued once.
1477 main.c At the end of each call to execute_command(), working_lang
1478 is checked against the local static (enum language)
1479 current. If they differ and working_mode is
1480 language_auto, the new settings of language, type and
1481 range checking are printed out.
1482 stack.c Modified frame_info() to include the language of the
1483 current frame in the output of "info frame".
1484 language.[ch] Added the function language_str() which returns the name
1485 of the current language.
1487 Fri Jun 28 15:33:14 EDT 1991
1489 m2-exp.y Added the built-in procedures INC, INCL, DEC, and DECL to
1490 the language. INCL and DECL currently cause an error,
1491 since sets are not implemented yet. INC and DEC are
1492 implemented as PREINCREMENT/PREDECREMENT with one
1493 argument, and as ASSIGN_MODIFY with two arguments.
1494 eval.c Added type checking to the above cases.
1495 value.h Added not_lval_constant to the lval_type ennumerated type.
1496 not_lval_constant means that the value is a constant
1497 value; that is 3 or 'a' or TRUE, not as in a constant
1498 identifier. This is used to help coerce numbers such as 3
1499 to either signed or unsigned numbers.
1500 valops.c Added the function value_coerce_constants() which coerces
1501 constant integers as following: if one is a constant and
1502 the other is not, the constant's type is set to the type
1503 of the other argument. If both are constants and one is
1504 signed, the other is converted to a signed constant.
1506 Sat Jun 29 17:26:29 EDT 1991
1508 valarith.c Added a better range checker. It now checks range
1509 (successfully) on integral operations [+-] (signed and
1510 unsigned) for any C sized type. Still does not work well
1511 for multiplication.)
1512 int_in_size() returns an integer that is coerced to fit into
1513 specified number of bytes.
1515 Mon Jul 1 13:04:14 EDT 1991
1517 language.[ch] Added the function binop_result_type(), which returns the
1518 builtin (struct type *) type that would be the result of a
1519 binop on the two values V1 and V2.
1521 Wed Jul 3 19:22:53 EDT 1991
1523 source.c Extended source_info() to include the source language in
1524 the output from "info source".
1526 Fri Jul 5 13:48:52 EDT 1991
1528 utils.c Moved the support functions for the GDB set/show commands
1529 dealing with language into language.c.
1530 language.c Added the function language_info(), which displays info
1531 about the current working language, type and range check
1532 settings. Called via the GDB command "info language".
1533 Added an initialization routine _initialize_language(),
1534 that sets defaults for the language, type and range
1535 variables and sets up the new GDB commands.
1536 main.c Language setup moved to language.c.
1539 Mon Jul 8 10:10:22 EDT 1991
1541 valarith.c Debugged the range checker for arithmetic. Still does not
1542 work for multiplication very well.
1544 Mon Jul 8 12:40:37 EDT 1991
1546 language.[ch] Added the function value_true() which returns non-zero if
1547 its argument represents a boolean true value.
1548 breakpoint.c Changed breakpoint_cond_eval() to call value_true() to
1549 check the truth of an expression.
1551 Thu Jul 11 12:51:34 EDT 1991
1553 language.[ch] Added the predicate structured_type(), which returns
1554 non-zero if the argument is a structured type.
1555 Added the predicate pointer_type(), which returns non-zero
1556 if the argument is a pointer type.
1557 eval.c Added the ability to do addition and substraction on
1558 pointers and integers. This case simply bypasses the
1561 Thu Jul 11 14:41:42 EDT 1991
1564 Added the symbol N_DEFD (0x4a) which is a definition
1565 module dependency that is used by the GNU Modula-2
1566 compiler and the linker. It is not important to GDB,
1567 except that [dbx|coff|mips]read.c should ignore these
1570 Fri Jul 12 16:07:00 EDT 1991
1572 valprint.c Changed the TYPE_LENGTH(type) >= 0 to TYPE_LENGTH(type) >
1573 0 in val_print(). Also added statements to the else part
1574 to coerce type (argument to val_print) to a pointer type
1575 if it is an "array of unspecified length".
1576 valops.c Added the function value_m2_string(), which returns a
1577 (value) value which is a constant string, whose type is
1578 (ARRAY [0..n] OF CHAR). The length field of the type
1579 structure is set to zero, so it will be interpreted as an
1580 "array of unspecified length".
1581 stack.c Moved the language/frame mismatch check to
1582 main.c:execute_command().
1583 main.c The working language is recorded each time
1584 execute_command() is executed. If working lang has
1585 changed during its execution, then the new
1586 language/type/range info is printed out for the user. If
1587 the working language does not match the language of the
1588 frame, a warning is issued.
1590 Sat Jul 13 16:16:39 EDT 1991
1592 eval.c Moved all the type-checking stuff for operators to
1593 language.[ch] language.c. This is so we can keep language-specific
1594 stuff (like for what type operators are defined) in
1596 language.[ch] Added the function binop_type_check(), which checks to see
1597 if its two (value) arguments are type-compatible with its
1598 opcode argument. The opcode should represent an operation
1599 involving an operator. Also added the macro function
1600 unop_type_check, which calls binop_type_check with a
1601 NULL second argument.
1602 expprint.c Added Modula-2 operators to the op_print_tab, so info
1603 expression.h break works correctly. Also added "op_string", which
1604 returns the string corresponding to the (enum exp_opcode)
1605 opcode that is its argument.
1608 Sat Jul 13 18:26:18 EDT 1991
1610 coffread.c Added code to record the type of function arguments with
1611 each paricular function. Code is very similar to that
1613 dbxread.c Moved add_param_to_type() to symtab.c
1614 symtab.[ch] Added function add_param_to_type() from dbxread.c
1616 *** NOTE: The above additions have not been tested.
1618 Mon Jul 15 12:50:47 EDT 1991
1620 langauge.[ch] Added the functions type_error and range_error, which work
1621 like error() except if the type/range mode is set to
1622 *_mode_warn, then they do not do a return_to_top_level(),
1623 but merely print a warning.
1624 Also changed [set|show]_[type|range]_command() to support
1625 the new "warn" feature.
1627 Thu Jul 18 17:50:54 EDT 1991
1629 mipsread.c Added code to record the type of function arguments with
1630 each particular function. Code is very similar to that
1633 *** NOTE: The above additions have not been tested.
1635 Fri Jul 19 11:19:10 EDT 1991
1637 defs.h Added macros MAX_OF_SIZE, MIN_OF_SIZE, UMAX_OF_SIZE, and
1638 UMIN_OF_SIZE, which when given a size of a numeric type,
1639 return the maximum and minimum value it can hold. UMAX...
1640 and UMIN... return the result for unsigned types.
1641 symtab.h Added the macros MAX_OF_TYPE and MIN_OF_TYPE to operate on
1642 struct types. They call above macros.
1643 dbxread.c Renamed the MAX and MIN_OF_TYPE macros to ..._OF_CTYPE to
1644 avoid a name conlict with the above.
1645 c-exp.y Added range checking on numeric constants in
1646 parse_number() for completeness.
1647 valarith.c Made binop_user_defined_p() and unop_user_defined_p()
1648 return 0 if working_lang is not language_c.
1650 Thu Aug 8 14:17:22 EDT 1991
1654 breakpoint.c Documentation strings of some commands changed to
1655 eliminate the references to the C language where
1658 Tue Aug 13 15:48:03 EDT 1991
1660 m2-exp.y Added qualified identifiers to the grammar. The semantics
1661 are slightly different from those of the GDB operator ::
1663 m2-exp.y Added a rule to each grammar of the form: start ::= exp |
1664 type_exp, where type_exp is any valid type expression.
1666 eval.c Added the opcode OP_TYPE, and an error case in eval.c.
1667 printcmd.c Modified ptype_command() so it actually parses the input
1668 (necessary for type expressions with scope qualifiers).
1669 Added the function ptype_eval() which expects an
1670 expression composed of one OP_TYPE element.
1671 *.[ch] Replaced all occurences of parse_c_expression with
1673 *.[ch] Replaced all occurences of parse_c_1 with parse_exp_1
1675 [End of ChangeLog entries from Andrew Beers for Modula-2 support.]
1677 Mon Sep 16 17:19:46 1991 John Gilmore (gnu at cygnus.com)
1679 Small fixes from Peter Schauer:
1681 * infrun.c (child_attach): Lint.
1682 * solib.c (find_solib): Handle shared libs version 2.
1684 Small fixes from David Wood:
1686 * xm-ultra3.h (SYS_SIGLIST_MISSING): Typo.
1690 * remote-vx.c: Move <stdio.h> to top, for FILE. Fix from
1691 John S <basrai%kanga.dnet@c3po.sm-alc.af.mil>.
1693 * utils.c (wrap_here): Avoid wrap action of fputs_filtered if
1694 chars_per_line is at maximum (user typed `set width 0'). Fix
1695 from Andreas Schwab <schwab@ls5.informatik.uni-dortmund.de>.
1697 Tue Sep 17 17:31:04 1991 Stu Grossman (grossman at cygnus.com)
1699 * coredep.c: include ptrace.h where necessary.
1700 * mipsread.c(parse_lines): fix unsigned char problem that was
1701 messing up line numbers on SGI's and possibly other MIPS based
1703 * infrun.c (child_create_inferior): use better test to check
1704 return val from setpgrp().
1705 * tm-irix3.h, xm-irix3.h, tconfig/irix3, xconfig/irix3: add these
1706 for sgi/irix support.
1708 Wed Sep 18 04:33:31 1991 Per Bothner (bothner at cygnus.com)
1710 * mipsread.c (parse_symbol): Put non-static procedures
1711 in the global block.
1713 Fri Sep 13 00:14:52 1991 John Gilmore (gnu at cygnus.com)
1715 Patch together `text_start' and `text_end' for 29K port.
1717 * exec.c (exec_command): If NEED_TEXT_START_END, define the
1718 variables and set them based on the exec file.
1719 * am29k-tdep.c: declare text_start.
1720 * valops.c (call_function_by_hand): declare text_end.
1722 * inferior.h: Eliminate CANNOT_EXECUTE_STACK in favor of
1723 defining CALL_DUMMY_LOCATION as BEFORE_TEXT_END. This is
1724 because machines that do this will also have to know to
1725 set NEED_TEXT_START_END. Besides, it was a redundant way to
1727 * tm-29k.h, tm-convex.h, tm-np1.h: Eliminate
1728 CANNOT_EXECUTE_STACK, define CALL_DUMMY_LOCATION and
1729 NEED_TEXT_START_END.
1731 Thu Sep 12 00:22:24 1991 John Gilmore (gnu at cygint.cygnus.com)
1733 AMD 29000 changes from David Wood <wood@david.ultra.nyu.edu>:
1735 * Makefile.in (CLIBS): Put XM_CLIBS and TM_CLIBS at end.
1736 Pass MUNCH_DEFINE to munch whenever we run it.
1737 * am29k-pinsn.c (print_insn): Handle NOP specially. Avoid %#x
1738 format string; use 0x%x instead.
1739 * am29k-tdep.c: Use DUMMY_SAVE_GREGS and RETURN_REGNUM.
1740 * ultra-xdep.c, xm-ultra.h: New files for Ultracomputer host system.
1741 * xm-rtbsd.h: New host support for RT/PC running BSD Unix.
1742 * inflow.c: Handle `short' process group IDs.
1743 * infptrace.c (fetch_register): Support CANNOT_FETCH_REGISTER,
1744 and check for ptrace errors.
1745 * coffread.c (SDB_REG_TO_REGNUM): Define if not already.
1746 (coff_symfile_init): Initialize text_bfd_scnum.
1747 (read_coff_symtab): Use it to find the text [and absolute?] sections.
1748 * ../config.sub: Add vendor nyu and os "sym[1-9]*".
1749 * configure.in: Add hosts rtpc-*-* and a29k-*-*.
1750 Merge target arm case with other "easy" cases. Add target
1751 cases a29k-*-none (rehack of am29k), a29k-*-kern (remote to
1752 Ultracomputer kernel), and a29k-*-sym1 (ultracomputer OS's user
1754 * minimon.h, remote-adapt.c, remote-mm.c: Add.
1755 * munch: Cope with RT/PC putting fns in data segment.
1756 Restore ability to override `nm' by specifying MUNCH_NM.
1757 * xconfig/rtbsd, xconfig/ultra3: New host systems.
1758 * tconfig/a29k: Rename from tconfig/am29k. Add remote-mm
1759 and remote-adapt. Remove encapsulated coff #define's (the
1760 support should go in BFD, and gdb shouldn't know or care).
1761 * tconfig/a29k-kern: Same, but for remote kernel debugging.
1762 * tconfig/ultra3: For debugging user processes on Ultra3/Sym1.
1763 * tm-29k.h: Update BADMAG (though it should go away).
1764 Allow the register definitions to be overridden in another
1765 tm-file. Fix SR_REGNUM. Add a mess of _REGNUM's. Separate
1766 RETURN_REGNUM from GR96_REGNUM and DUMMY_SAVE_GREGS from
1767 DUMMY_SAVE_GR96, for handling kernel calling conventions
1768 that use GR64+ rather than GR96+.
1769 * tm-ultra3.h: New file, for use on Ultra3 Unix as well as for
1770 remote debugging of Ultra3 kernel. Includes tm-29k.h and
1771 overrides various things.
1773 * remote-mm.c (mm_attach, mm_wait): Handle attach like
1774 child_attach does, making a clean stop in the newly attached
1776 * remote-eb.c: Lint.
1778 * coffread.c: Make coffread independent of any particular
1779 variant of COFF. Avoid #include-ing any particular one except
1780 internalcoff.h. BFD now passes key values for symbol reading
1781 as part of its coff_data structure (LINESZ, SYMESZ, AUXESZ,
1782 and the symbol masks and shifts); use them.
1783 Remove obsolete end_of_text_addr.
1785 * exec.c: Remove unused include files.
1787 Wed Sep 11 19:38:44 1991 John Gilmore (gnu at cygint.cygnus.com)
1789 * Makefile.in (documentation targets): Pass $(M4).
1790 Bugfix from eggert@twinsun.com (Paul Eggert).
1792 * stack.c (down_silently_command): Check for stack existence.
1794 Tue Sep 10 23:08:29 1991 John Gilmore (gnu at cygint.cygnus.com)
1796 * Makefile.in (VERSION): Update to 4.0.3.
1798 Tue Sep 10 09:19:29 1991 John Gilmore (gnu at cygint.cygnus.com)
1800 * core.c (core_file_command): Print frame at coredump with
1801 its level number, by calling print_stack_frame.
1802 * frame.h: Add selected_frame_level, print_stack_frame.
1803 * frame.h, stack.c: Remove print_sel_frame, print_selected_frame.
1804 * convex-tdep.c, convex-xdep.c, infcmd.c, inflow.c, infrun.c:
1805 Change print_sel_frame and print_selected_frame callers to
1808 * dbxread.c (read_ofile_symtab): Avoid empty else clause.
1809 * symfile.c (free_named_symtabs): Ditto.
1810 * main.c (main): wrap_here needs an arg.
1811 * solib.c (find_solib): Avoid memory access if _DYNAMIC is zero.
1812 (solib_add): Avoid noise.
1813 (solib_create_inferior_hook): Lint.
1814 (sharedlibrary_command): Move dont_repeat to here.
1815 * utils.c (error): Call wrap_here to force buffered output.
1817 Small patches from Peter Schauer:
1819 * coffread.c (start_symtab): Free any existing line_vector before
1821 (read_coff_symtab): Ditto for type_vector.
1823 * source.c (lines_to_list): New variable, replacing function.
1824 (all uses): Use as variable.
1825 (_initialize_source): Add 'set listsize' and 'show listsize'.
1826 * utils.c (lines_to_list): Remove function.
1827 * stack.c (print_frame_info): Use as variable.
1828 * defs.h (lines_to_list): Remove declaration.
1830 Mon Sep 9 13:45:57 1991 John Gilmore (gnu at cygint.cygnus.com)
1832 * breakpoint.c (insert_breakpoints): Restore warning about
1833 the program might be running in another process, but only for
1834 systems with this brain death (#ifdef ONE_PROCESS_WRITETEXT).
1835 * xm-hp300bsd.h, xm-mips.h, xm-vax.h: Define it.
1837 * utils.c (error): if error_pre_print is set, print the string
1839 * main.c (main, print_gnu_advertisement, print_gdb_version):
1840 Reformat legalese so it always prints, but acts as an "I'm here"
1841 message while symbols are being read. If any errors occur,
1842 print a few newlines to set off the message and start it at the
1843 left margin. Remove mention of "help" command, and don't yak
1844 about symbol reading.
1845 (catch_errors): Error string is now printed first in case of
1847 * command.c (undef_cmd_error, lookup_cmd): On undefined command,
1848 suggest the "help" command.
1850 * Makefile.in (VERSION): Set to 4.0.2.
1852 Thu Sep 5 23:49:48 1991 John Gilmore (gnu at cygint.cygnus.com)
1854 * .gdbinit: Remove useless "rr" command. Set complaints
1855 to 1 for people debugging gdb.
1857 * breakpoint.c, remote-vx.c: Reword strings printed by
1858 catch_errors callers.
1860 Wed Sep 4 11:07:50 1991 John Gilmore (gnu at cygint.cygnus.com)
1862 * WHATS.NEW: "history write -> history save". Doc "write on/off".
1863 (Fix from kenc@viewlogic.com.)
1865 Fix some infrastructure to be able to cope with host and target
1866 machines with different sized basic types (ints, ptrs, etc).
1867 (Idea from pierre@la.tce.com (Pierre Willard).)
1869 * values.c (value_from_longest): Rename from value_from_long.
1870 Handle pointer types as well as integers, so that targets with
1871 different pointer sizes from the host can be accomodated.
1872 * breakpoint.c, convex-tdep.c, eval.c, expprint.c, printcmd.c,
1873 valarith.c, valops.c, valprint.c, value.h, values.c: Rename
1874 uses of value_from_long to value_from_longest.
1875 * eval.c, findvar.c, printcmd.c, valarith.c, valops.c: Pass
1876 the correct pointer type to value_from_long{est}.
1878 * doc/gdb.texinfo ($_, $__): Describe types of these variables.
1880 * remote-vx.c: Remove obsolete code for calling functions via
1881 vxworks kludge interface (it referenced value_from_long).
1883 * valops.c (value_string): Find malloc with lookup_misc_func, not
1886 Tue Sep 3 18:37:46 1991 John Gilmore (gnu at cygint.cygnus.com)
1888 Make writing to files work properly. (Fixes to BFD are also needed.)
1890 * core.c (core_open): Open file ourselves, read or r/w, depending on
1891 write_files. Use bfd_fdopenr.
1892 * gdbcore.h (write_files): New variable.
1893 * exec.c (write_files): Define variable, add set&show for it.
1894 (exec_file_command): Use write_files to open for read or r/write.
1896 Make shared library reading happen automatically. These changes
1897 are mostly from Peter Schauer <pes@regent.e-technik.tu-muenchen.de>.
1899 * inferior.h (stop_soon_quietly): Add to exported variables.
1900 * infrun.c (child_create_inferior): call solib hook, if defined.
1901 (child_attach): call solib hook, if defined.
1902 * solib.c: Include inferior.h. Add from_tty to so_list as kludge.
1903 (find_solib): Use lookup_misc_func rather than hand-rolled.
1904 (symbol_add_stub): New stub for catch_errors.
1905 (solib_add): Avoid output if !from_tty. Catch errors rather
1906 than just calling symbol_file_add and bombing.
1907 (solib_create_inferior_hook): Interface with the target process
1908 to let it read and alloc shared libs, then figure out what it did.
1910 * core.c (validate_files): Fix typo, soften warning.
1911 (Fix from Hiroto Kagotani <kagotani@cs.titech.ac.jp>.)
1913 * utils.c (fputs_demangled): Avoid duplicate printing if
1914 demangling is off. (Fix from J.T. Conklin <jtc@cayenne.com>.)
1916 * infrun.c (proceed): Cast -1 to (CORE_ADDR) before comparing.
1917 (Fix from pierre@la.tce.com (Pierre Willard).)
1919 * main.c (catch_errors): Change argument to a char * from an int,
1920 since a char * can point to a struct full of glop, but an int
1921 is not guaranteed to be able to hold a pointer.
1922 * breakpoint.c (breakpoint_cond_eval, bpstat_stop_status,
1923 breakpoint_re_set_one, breakpoint_re_set): Adapt.
1924 * core.c (core_open, solib_add_stub): Adapt.
1925 * remote-vx.c (symbol_stub, add_symbol_stub, callers): Adapt.
1927 Wed Aug 28 18:18:05 1991 John Gilmore (gnu at cygint.cygnus.com)
1929 * Makefile.in: Update VERSION to 4.0.1. Evade GNU Make bug
1930 by adding .NOEXPORT target.
1932 Fri Aug 23 17:14:25 1991 John Gilmore (gnu at cygint.cygnus.com)
1936 * Makefile.in (VERSION): Roll to 4.0.
1937 (gdb.tar.Z): Make refcard.ps as well, for shipment.
1939 Fri Aug 23 14:07:09 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1941 * doc/gdb.texinfo: minor rewordings, crossref to ptype from print,
1944 * doc/Makefile, Makefile.in: generate "gdb-all.texi" rather than
1947 * doc/rdl-apps.texi: renamed from rdl-apps.texinfo
1949 * Makefile.in, doc/Makefile, doc/.Sanitize, doc/gdb.texinfo:
1950 reflect above name change
1952 * WHATS.NEW: correct pointer to refcard.
1954 * doc/gdb.texinfo: update New Features, Installing
1956 * doc/gdbint.texinfo: add short description of configure +template
1958 Fri Aug 23 11:46:08 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1960 * doc/gdb.texinfo: update, fix bugs in "Installing" appendix
1962 Fri Aug 23 01:02:00 1991 John Gilmore (gnu at cygint.cygnus.com)
1964 * Makefile.in: Add config.sub, make doc/rdl-apps.texinfo for
1965 tar file, add dependencies for referenced doc files.
1967 Thu Aug 22 22:17:06 1991 Stu Grossman (grossman at cygint.cygnus.com)
1969 * coffread.c, symfile.c, stack.c: saberized.
1971 Thu Aug 22 16:20:27 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1973 * doc/refcard.tex: permuted Essential Commands sec
1975 * doc/gdb.texinfo: new C++ chapter; revised installation appendix;
1977 set/show symbol-reloading
1978 default set complaints 0
1980 RET-repeat disabled after prompted long displays
1981 processID (attach) interpretation of 2nd GDB cmdline arg
1983 Thu Aug 22 14:05:47 1991 Stu Grossman (grossman at cygint.cygnus.com)
1985 * expread.y, coffread.c, dbxread.c, target.c, mem-break.c,
1986 cplus-dem.c, values.c, valprint.c, symfile.c, remote.c,
1987 breakpoint.c, main.c: lint.
1989 Thu Aug 22 02:02:26 1991 John Gilmore (gnu at cygint.cygnus.com)
1991 Install new configuration scheme for GDB and friends.
1993 * config.sub: Translate ordinary names to three-part names.
1994 * configure: Use three-part names internally.
1995 * configure.in: Translate three-part names to filenames.
1997 * README, WHATS.NEW: Update for gdb-4.0.
1998 * Makefile.in: Roll VERSION to 3.99.
2000 Wed Aug 21 18:21:09 1991 John Gilmore (gnu at cygint.cygnus.com)
2002 * infptrace.c (KERNEL_U_ADDR_BSD): Include a.out.gnu.h.
2003 * i960-tdep.c, m68k-tdep.c, sparc-tdep.c, tm-i960.h,
2004 tm-m68k.h, remote-nindy.c: Change ext_format_XXX structs
2005 to single structures rather than arrays; when passing
2006 their address, use &. This avoids trouble with bdead compilers.
2007 * mcheck.c: Don't include <stdlib.h>; just declare "void abort();"
2008 instead. This avoids portability headaches.
2009 * mips-tdep.c (mips_do_registers_info): Only print FP regs if
2011 * source.c (open_source_file): Avoid ANSI const bdeath by
2012 skipping declaration and then casting result value.
2013 * tm-hp300bsd.h: Clarify comment.
2014 * utils.c (strstr): Result is const char *; ANSI bdeath.
2015 * xm-hp300bsd.h: Define HOST_BYTE_ORDER. Redefine INT_MIN,
2016 since system include file defines it differently from "defs.h",
2017 though the two are equivalent for our purposes.
2018 * tconfig/hp300bsd: Add m68k-tdep.o.
2020 Tue Aug 20 16:01:11 1991 John Gilmore (gnu at cygint.cygnus.com)
2022 * tconfig/sun*4: Remove warnings about system assembler.
2024 Mon Aug 19 13:44:46 1991 John Gilmore (gnu at cygint.cygnus.com)
2026 * mcheck.c: Avoid warning about undeclared abort fn.
2027 * tm-sparc.h (PC_ADJUST): Avoid calling error() from this;
2028 it causes recursive calls to error() when used in cleanups.
2029 To do so requires that we make it a function, so we do.
2030 * sparc-tdep.c (sparc_pc_adjust): New implem of PC_ADJUST.
2031 * utils.c (do_cleanups): Remove the current cleanup from the
2032 chain *before* calling it, in case error() is called from it.
2033 The result won't be pretty, but won't be an infinite loop either.
2035 Mon Aug 19 00:41:04 1991 Michael Tiemann (tiemann at cygint.cygnus.com)
2037 * dbxread.c (read_struct_type): Grok anon structs for C++.
2038 (vb_name, vptr_name): Null terminate these strings.
2040 Fri Aug 16 08:31:03 1991 John Gilmore (gnu at cygint.cygnus.com)
2042 Minor bug fixes from BSD Net2 gdb:
2044 * blockframe.c (get_prev_frame_info): If FRAME_CHAIN_COMBINE
2045 returns 0, there is no previous frame.
2046 * breakpoint.c (commands_command): If !from_tty, don't call
2047 input_from_terminal_p().
2048 * dbxread.c (record_misc_function): Speed up slightly.
2049 (compare_psymbols): Ditto.
2050 * infcmd.c (do_registers_info): Take a second argument to
2051 determine whether to print float registers. "info registers"
2052 does not do so anymore. "info all-registers" does, now.
2053 * mips-tdep.c, pyr-tdep.c (xxx_do_registers_info): Take second
2055 * tm-mips.h, tm-pyr.h (DO_REGISTERS_INFO): Pass second arg.
2056 * inflow.c (initialize_inflow): Set tflags_ours correctly.
2060 * breakpoint.c (bpstat_do_actions): Use a cleanup to restore
2061 executing_breakpoint_commands if we are interrupted by error.
2062 * coffread.c (init_lineno): Avoid problem with zero-sized linetab
2063 versus malloc/free. From: john@labtam.labtam.oz.au (John Carey).
2064 * core.c (solib_add_stub, core_open): Call SOLIB_ADD inside a
2065 catch_errors() so we can setup the frame regardless of whether
2066 the shared libs work.
2067 * ieee-float.c (double_to_ieee_extended): Get exponent from
2068 right place in little-endian systems. From John Carey.
2070 Thu Aug 15 18:43:57 1991 John Gilmore (gnu at cygint.cygnus.com)
2072 * main.c: Remove unused terminating_signals and catch_termination().
2073 (long_options): Terminate with a zero element.
2074 [Bugfix from Atsuo Kawaguchi <atsuo@hark86.harl.hitachi.co.jp>.]
2075 (gdb_readline): Make call-compatible with readline.
2076 (init_signals): Improve comments re vfork vs. signal.
2078 * utils.c (prompt_for_continue): Use new gdb_readline().
2079 If we prompt for continuation, we don't let CR repeat the previous
2080 command, once we get back to a prompt. It's too easy to keep
2081 hitting CR, expecting "--more--" prompts, and have some long
2082 command start repeating on you.
2084 Tue Aug 13 16:17:56 1991 John Gilmore (gnu at cygint.cygnus.com)
2086 * blockframe.c (frameless_look_for_prologue): Speed up by
2087 calling SKIP_PROLOGUE_FRAMELESS_P if it's defined.
2088 * tm-sparc.h (SKIP_PROLOGUE, SKIP_PROLOGUE_FRAMELESS_P):
2089 Define two variants, one faster.
2090 * sparc-tdep.c (sparc_frame_chain): Use target_read_memory
2091 and return zero, rather than giving an error.
2092 (setup_arbitrary_frame): Initialize the PC in the new frame.
2093 (skip_prologue): Add a second arg saying whether we're just
2094 checking for a frameless function or not.
2096 * core.c (core_open, core_close, core_xfer_memory): Move
2097 section table pointers and bfd* into the target_ops.
2098 (core_open): Allow errors in shared lib reading, etc.
2099 (core_files_info): Describe shared library sections.
2101 * exec.c (exec_open, exec_close, exec_xfer_memory, xfer_memory,
2102 exec_files_info, set_section_command): Move section table
2103 pointers and bfd* into the target_ops.
2104 (add_to_section_table): Add BFD to section table.
2106 * target.c (target_xfer_memory, target_info): Pass target to
2107 xfer_memory and target_info functions.
2110 * gdbcore.h: Move struct section_table.
2111 * target.h: New home of struct section_table.
2113 * solib.c (solib_add): New argument is the target_ops whose
2114 section list is to be added to, if any. Reallocate the
2115 sections in that target to add any that come from shared libs.
2116 (throughout) so_sections renamed to sections.
2117 (solib_xfer_memory): Deleted.
2118 * tm-sunos.h (SOLIB_ADD): Add target argument.
2119 (SOLIB_XFER_MEMORY): Delete.
2121 * core.c, exec.c, inftarg.c, remote-eb.c, remote-nindy.c,
2122 remote-vx.c, remote.c, target.c, target.h: Remove add_syms vector
2123 from target_ops. It's the same on all targets. Add two section
2124 pointers to target_ops.
2126 * stack.c (find_relative_frame): Dump ancient algorithm for
2127 "down", just use handy "next" pointers.
2128 (frame_command): Don't error if there is no stack; let user
2131 * inflow.c (new_tty_prefork, new_tty): New prefork routine
2132 modifies static state in the parent process; new_tty itself
2133 runs in the child and modifies the child's file descriptors
2134 to match the saved static state.
2135 * infrun.c (child_create_inferior): Call new_tty_prefork,
2138 * infptrace.c (child_xfer_memory): Add ignored target arg.
2139 * remote-eb.c (eb_xfer_inferior_memory): ''
2140 * remote-nindy.c (nindy_xfer_inferior_memory): ''
2141 * remote-vx.c (vx_xfer_memory): ''
2142 * remote.c (remote_xfer_memory): ''. Rename from
2143 remote_xfer_inferior_memory.
2145 * main.c (main): Only try to attach "corefile" argument if
2146 it starts with a digit.
2148 * symfile.c (symbol_reloading): New "set/show" variable.
2149 (symbol_file_add): Shorten message about symbol reading.
2150 (add_symbol_file_command): Merge with add_syms_addr_command,
2151 since this should work on all targets now.
2152 (stop_whining): Default to zero, to shut up complaints
2153 about bad symbol tables on many systems.
2154 (free_named_symtabs): Just exit unless symbol_reloading.
2156 * xm-sun3os4.h, xm-sun4os4.h: Define BROKEN_LARGE_ALLOCA,
2157 and add comment explaining shared library screw.
2159 * source.c: #if defined => #ifdef.
2161 Thu Aug 8 12:23:19 1991 John Gilmore (gnu at cygint.cygnus.com)
2163 * doc/gdbint.texinfo: Improve doc on porting to new OS's.
2165 Tue Aug 6 17:16:15 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
2167 * doc/rdl-apps.texinfo: provide default readline-appendix finder
2168 (doc/Makefile knows how to make one for local config)
2170 * Makefile.in: use doc/Makefile for doc targets
2172 * doc/Makefile: GDB documentation now has its own Makefile
2173 doc/refcard.tex: renamed from "gdbrc.tex"
2174 doc/.Sanitize: add Makefile; recognize renamed refcard.tex
2175 doc/gdbint.texinfo: add markup in "Cleanups" chapter
2178 Fri Aug 2 00:13:06 1991 John Gilmore (gnu at cygint.cygnus.com)
2180 * values.c (baseclass_addr): When reading target memory, use the
2181 length of the basetype, not the upper type. We've only malloc'd
2182 enough space for the basetype, leading to errors in free().
2184 * expprint.c (print_subexp): Print UNOP_MEMVAL of an OP_LONG that
2185 ends up as a function specially, since we know the actual type of
2186 the pointed-to address. This (somewhat) fixes display of
2187 expressions that include misc_function_vector names. Try `cond 1
2188 !strcmp("a","b")' then `i b'.
2190 * infrun.c: Move DO_DEFERRED_STORES from proceed() to resume().
2191 The child can be proceeded from inside wait_for_inferior in
2192 evaluating breakpoint conditions, and DO_DEFERRED_STORES was
2193 getting skipped in that case.
2195 * expprint.c (print_subexp): Use filtered output, since the
2196 subroutines we call use it, otherwise the output is horribly
2197 mangled, since output of wrappable stuff comes out late.
2199 * Makefile.in: Bump VERSION to 3.98.1
2201 * infrun.c (child_create_process): Use execlp to find the
2202 shell to exec our target program. This requires some fiddling
2203 with `environ' since there is no execlpe().
2205 Thu Aug 1 15:35:17 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
2207 * Makefile.in, doc/gdbrc.tex, doc/rc-* (new files):
2208 Minor rearrangement of refcard permits two new make targets--
2209 gdbrc.dvi DVI output for refcard, using CM fonts
2210 gdbrc.ps PostScript refcard, using PS fonts
2212 Wed Jul 31 16:46:21 1991 John Gilmore (gnu at cygint.cygnus.com)
2216 * TODO, Projects, WHATS.NEW, README: Update for gdb-3.98.
2217 * Makefile.in (gdb-all.texinfo): Avoid touching file if M4 dies.
2219 Wed Jul 31 16:35:58 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
2221 * doc/gdb.texinfo: last changes for release.
2222 Minor typo and formatting fixes; incorporated most fixes remaining from
2223 filed mail commenting on earlier drafts.
2225 Added warnings: pipes don't work in run command;
2226 conditions are converse of assertions;
2227 step over fn without debug info goes to next fn;
2228 vars may have "wrong" values near fn entrance, exit
2230 Added example from Kingston on printing repeated nonadjacent values
2232 Added explicit mention that in Emacs gdb mode C-c and C-z are like
2233 shell mode for signals
2235 Renamed "Stepping and Continuing" to "Continuing and Stepping" so it
2236 doesn't sound so much like its parent "Stopping and Continuing"; also
2237 moved entries on continue to top of section, so they don't get lost.
2239 Improved installation directions in appendix, added manual formatting
2242 Tue Jul 30 17:26:39 1991 John Gilmore (gnu at cygint.cygnus.com)
2244 * configure.in: Remove xm.h and tm.h even if we aren't linking
2245 new ones, so "./configure sun4; ./configure none" does the right
2246 thing. Assume that alldeps.mak and depend are already built in
2247 srcdir, and avoid running "make" (particularly "make depend",
2248 which involves "gcc") from inside configure. Build Makefile
2249 directly rather than building Makefile.conf first.
2250 * configure: Regenerate with above changes.
2251 * Makefile.in: Use $(BISON) to find bison. Roll VERSION
2252 to 3.98. Revise gdb.tar.Z procedure to produce a file
2253 called gdb-$(VERSION).tar.Z but which unpacks into a
2254 directory called "gdb". Move non-source files out of
2255 $(SFILES_SUBDIR). Pretty up alldeps.mak with comments.
2256 (depend): Don't try to do "gcc expread.y".
2257 (expread.o): Update dependencies by hand.
2259 Mon Jul 29 15:21:09 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
2262 Fixed a variety of small typos that prevented info from formatting
2263 cleanly; altered too-long heading for GPL Appendix, as discussed
2264 w/RMS; Changed date on cover to July 91.
2266 Fri Jul 26 13:20:02 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
2269 (1) Applied some fixes due to comments from Larry Breed (easier ones
2270 through chapsec 5.2)
2271 (2) Eliminated use of @footnote---had my doubts about it anyways, and
2272 it's broken in latest texinfo
2273 (3) Introduced *some* use of [] for optional arguments, where
2274 explanation is not simpler by listing cmd w arg and cmd w/out arg
2275 separately. Still not using @deffn.
2276 (4) Dropped in GPL-2. NOTE: one of GPL-2 or texinfo is broken; a
2277 couple of headings are too long. Need patches to texinfo or revision
2280 * Partial update to README (which still needs work for this
2281 release!): (1) use of configure corrected for new script,
2282 (2) "make gdb.dvi" and "make gdb.info" mentioned.
2284 Wed Jul 24 06:44:02 1991 John Gilmore (gnu at cygint.cygnus.com)
2286 * symtab.c (lookup_symbol): Don't complain right off about
2287 no debug symbols; use the misc function vector first.
2288 (list_symbols): Use misc function vector to find symbols
2289 that don't have debug info, and print them.
2290 (find_pc_symtab): Temporarily avoid fatal() when psymtab
2291 PC range doesn't match symtab PC range, as it does on the
2292 MIPS because our symtab reading isn't perfect.
2294 * dbxread.c (dbx_symfile_read): Make warning about
2295 "no debug symbols" slightly nicer.
2297 * source.c (select_source_symtab): If "main" symbol exists,
2298 but decode_line_spec can't find line info, don't just return
2299 a zero; try other source symtabs or give an error.
2301 * mipsread.c (parse_partial_symbols): Sort the psymtabs by
2302 their low addresses first, then rip through fixing high addrs.
2304 * ns32k-opcode.h (sfsr): Bugfix from Rune Nerg}rd,
2305 <runene@ifi.uio.no>.
2306 (NS32K_SVC_IMMED_OPERANDS): Reverse the #ifndef.
2308 Tue Jul 23 18:52:43 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
2310 * Minor, mostly mechanical, cleanup of doc subdir for clean
2311 makeinfo'ing and TeXing; also ensured gdb-all.texinfo (post-m4)
2312 and gdb.info (post- texinfo2 makeinfo) generated for distribution.
2314 Sun Jul 21 03:54:52 1991 John Gilmore (gnu at cygint.cygnus.com)
2316 Mostly MIPS and general symbol-reading fixups.
2318 * doc/gdbint.texinfo: Add documentation on symbol-reading
2321 * mipsread.c: Remove kludges around #include "ecoff.h".
2322 Remove redefinitions of a_magic, etc, no longer used.
2323 (parse_symbol, ): Convert "Internal:" printfs to complain()ts.
2324 Fix global overview comments to match symfile.c protocol.
2325 (mipscoff_new_init): Eliminate cur_hdr if we have one.
2326 (mipscoff_symfile_read): Eliminate unused code. Avoid
2327 sorting all the symtabs, when all we have read here is psymtabs.
2328 The symtabs are sorted as they are created anyway. Tell
2329 condense_misc_bunches whether we're mainline.
2330 (psymtab_to_symtab_1): Pass filename when recursing, to make
2331 stack trace more informative.
2332 (parse_partial_symbols): Assume cur_hdr as argument.
2333 (read_mips_symtab): Don't clobber cur_hdr, so it can be freed.
2334 Pass cur_hdr implicitly to parse_partial_symbols. Avoid checking
2335 the TYPE_NAME of char *, since that's done in symfile.c.
2336 (free_numargs, parse_symbol, add_symbol, add_block,
2337 shrink_linetable): Declare these fns void.
2338 (upgrade_type): Convert tree of if's to switch. Clean up
2339 bogus "off == 0" handling with a complaint. Avoid setting
2340 field bitpos and bitsize of array with lower and upper bounds.
2341 Check specified bitsize of elements against their actual type's
2342 bitsize, and complain if different. Complain about unknown
2344 (parse_fdr): Don't assume sizeof(char *) == sizeof (struct *).
2345 (psymtab_to_symtab_1): Print names of subsidiary files that
2346 are being read in. FIXME, we read far too many files. This code
2347 is not the problem, the problem is in parse_fdr where the psymtabs
2349 (cross_ref): Result should indicate that we used one aux entry
2350 normally, or two if we encountered a "next" entry. This used
2351 to leave the caller pointing at the wrong aux entry.
2352 (add_symbol): If overflowed cur_block, reallocate it larger,
2353 chase all pointers to it, and complain(), rather than clobber memory.
2354 (shrink_block): Use xrealloc rather than xmalloc-and-copy.
2355 (new_field): Only allocate one field initially, not two.
2356 Pull ++ out of macro argument. Simplify.
2357 (_initialize_mipsread): Avoid initialization of importd
2358 global_psymbols and static_psymbols.
2360 * symfile.c (psymtab_to_symtab): Depend on XXX_psymtab_to_symtab
2361 to properly set pst->symtab; avoid searching for it.
2362 (symfile_fns): Improve comments, add a FIXME.
2363 * dbxread.c: Update comments to reflect symfile protocol.
2364 (read_ofile_symtab, end_symtab): Return the symtab.
2365 (psymtab_to_symtab_1): Set pst->symtab.
2367 * coffread.c (coff_symfile_read): tell condense_misc_bunches
2368 whether we're mainline.
2370 * symfile.h (sym_fns): Remove unused sym_discard member.
2371 * coffread.c, mipsread.c, dbxread.c: Remove XXX_symfile_discard.
2373 * mtrace.c (mtrace): Take effect if mallwatch is set, even if
2374 the environment variable is not.
2375 * infcmd.c (finish_command): Use filtered printfs.
2376 * cplus-dem.c: Add struct tags to a few unnamed structs.
2377 * valops.c (value_coerce_array): Improve comments.
2378 * valprint.c (type_print_varspec_suffix): Print array size only
2379 if greater than zero.
2380 * m88k-tdep.c: Shift some lines left by one space, that had
2381 apparently been trashed at some point.
2382 * TODO: More things to do, a few got done.
2384 Thu Jul 18 22:46:05 1991 John Gilmore (gnu at cygint.cygnus.com)
2386 * symtab.h (LOC_EXTERNAL): Eliminate in favor of LOC_STATIC.
2387 (ldsymoff, ldsymlen, globals_offset, statics_offset): Improve
2389 * dbxread.c (read_dbx_symtab): LOC_EXTERNAL -> LOC_STATIC.
2390 * expread.y, findvar.c, symmisc.c: Ditto.
2391 * printcmd.c (address_info): Update printed forms of LOC_
2392 symbols. Elim LOC_EXTERNAL.
2393 (print_frame_args): Keep track of param stack offsets before
2394 re-looking up to find the local register param is kept in.
2396 * mipsread.c: Use <symconst.h> and <sym.h> rather than <syms.h>.
2397 Further integration of mipsread into gdb. Eliminate unused
2398 routines, duplicate declarations. Handle static symbols in
2399 psymtabs as well as external symbols. When reading symtabs,
2400 insert symbols into the correct block (global, static, or a local
2402 (read_mips_symtab, parse_partial_symbols): Don't pass useless
2404 (mipscoff_symfile_read): Don't call select_source_symtab.
2405 (parse_symbol): Use SYMBOL_VALUE_ADDRESS where appropriate,
2406 rather than SYMBOL_VALUE.
2407 (parse_external): Comment clobbering of top_stack.
2408 (parse_partial_symbols): Update comments. Allocate and parse
2409 static symbols as well as external symbols. FIXME, enum values
2410 are not handled in this pass, but should be. Inline new_psymbol.
2411 Use SYMBOL_VALUE_ADDRESS.
2412 (psymtab_to_symtab_1): Read symbols into global static block
2413 by default (until enter some function's local block context).
2414 (sort_blocks): Clean up STATIC_BLOCK as well as GLOBAL_BLOCK.
2415 (destroy_all_symtabs, new_psymbol): Eliminate, unused.
2417 * source.c (select_source_symtab): Select a source symtab
2418 from either the symtabs or, failing that, the psymtabs.
2419 (list_command): Update error message.
2420 (forward_search_command, reverse_search_command): Use getc, not
2421 fgetc, for speed. FIXME, add comment about buffers that die if
2422 overrun by long line.
2424 * values.c (unpack_field_as_long, modify_field): Avoid shifting
2425 by an entire word, which is not portable, if we have a 32-bit
2426 field. (Code in dbxread.c already turns such bitfields, if
2427 aligned, into ordinary ints, but fixing this will help for other
2428 symbol formats and for future changes.)
2429 * core.c (core_open): Handle ANSI const brain death.
2430 * utils.c (vprintf): Fix varargs typo.
2432 Sun Jul 14 00:42:53 1991 John Gilmore (gnu at cygint.cygnus.com)
2434 * findvar.c (find_var_value): Handle &function better.
2435 * TODO: Document work needed on &fn and &array.
2436 * printcmd.c (print_address_symbolic): New arg is the prefix
2437 to print if a name is printed.
2438 (print_address_demangle): Honor "set print address" now.
2439 Use new arg above to improve spacing of output.
2440 * valprint.c (val_print): When printing function pointers,
2441 print symbolic form too.
2442 * breakpoint.c (breakpoint_1): Use new print_address_symbolic.
2444 Mon Jul 8 19:02:46 1991 John Gilmore (gnu at cygint.cygnus.com)
2446 * core.c (memory_error): Reword error msg to mislead less.
2448 * mips-pinsn.c (print_insn_arg 'd'): Print $ with reg name.
2450 * mipsread.c (read_mips_symtab, read_the_mips_symtab,
2451 parse_partial_symbols): Use newer BFD internals (external_filehdr
2452 and external_aouthdr), byte-swap the fields that we care about
2453 before using them, and make the file header data local to
2454 read_the_mips_symtab rather than global.
2456 Sat Jul 6 01:34:15 1991 John Gilmore (gnu at cygint.cygnus.com)
2458 * ns32k-opcode.h (movmw, movmd): Fix opcodes. Bug fix
2459 from Rune Nerg}rd <runene@ifi.uio.no> on 5 Jul 1991.
2461 * main.c (command_line_input): Flush stdout and stderr
2462 before every call to readline. This reportedly fixes a bug
2463 that comes up in Sys V running emacs-gdb and/or xxgdb,
2464 when stdin/out are pipes or sockets.
2466 Thu Jul 4 14:47:06 1991 John Gilmore (gnu at cygint.cygnus.com)
2468 * configure.in, Makefile.in: Avoid rebuilding "depend" as much.
2469 Avoid declaring Makefile dependencies, because GNU Make stupidly
2470 tries to update it if we do.
2472 * coffread.c: Revise for minor changes to bfd internal coff
2475 * configure: If -template= is given a relative path, make it
2476 absolute before recurring in subdirectories.
2478 * configure, configure.in, Makefile.in: Install "configure" script
2479 as replacement for config.gdb.
2480 * config.gdb, Makefile.dist, Makefile.sdir: Remove
2481 * README: Update for configure, mostly. FIXME.
2483 * Add dec3100 as equivalent to littlemips. Indicate in all host &
2484 target config files that they are for the host. When the lines
2485 get copied into the Makefile, this makes it more obvious what's
2488 Mon Jun 24 23:49:07 1991 John Gilmore (gnu at cygint.cygnus.com)
2490 * sparc-opcode.h (trap opcodes): Avoid leading spaces or
2491 tabs, which end up in the disassembler output inadvertently.
2493 Wed May 29 23:01:03 1991 John Gilmore (gnu at cygint.cygnus.com)
2495 Make it compile cleanly in an ANSI GCC2 environment.
2497 * blockframe.c: <stdio.h>
2498 * cplus-dem.c: free takes a void *, ifdef __STDC__
2499 * dbxread.c (read_huge_number): avoid gcc2 bug hoisting calc of
2501 * defs.h (alloca): Avoid doing anything if alloca already def'd.
2502 * stddef.h, stdlib.h: Remove these files.
2503 * symtab.c: Avoid declaring qsort, close.
2504 * symfile.c: Avoid declaring close.
2505 * utils.c (vprintf): Declare "ap" arg as proper va_alist.
2506 * sparc-tdep.c: Avoid including lots of Sun-host-specific files.
2508 Assorted other changes.
2509 * dbxread.c: include "libaout.h", not "liba.out.h".
2510 * printcmd.c (print_frame_args): Set recurse properly for
2511 indentation of struct and array parameters.
2512 * valops.c (value_cast): Allow cast to void.
2513 * infrun.c (resume): If NO_SINGLE_STEP, call machine dependent
2514 single_step() in a target-independent fashion.
2515 * sparc-tdep.c (single_step): Don't call ptrace ourselves, just
2516 set up to be ready to continue. This makes us target independent.
2517 * infptrace.c (child_resume): Remove call to single_step; now
2518 can single step a SPARC target of any kind.
2520 Wed May 22 18:18:24 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
2522 * Makefile.dist, doc/gdb.texinfo, doc/*-m4.texinfo: split up GDB
2523 docn into separate sections---basically chapters, plus two loose
2524 pieces that can be configured to go in different places. This
2525 allows GNU m4 to preprocess the manual without coredumping.
2527 * Makefile.dist: tell TeX where to find texinfo.
2529 Mon May 20 12:15:04 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
2531 * Makefile.dist, doc/gdb.texinfo: respectively create, and use,
2532 the new target "rdl-apps.texinfo" which captures the Makefile
2533 variable that records where to find the Readline libraries.
2535 Sun May 19 05:36:59 1991 John Gilmore (gnu at cygint.cygnus.com)
2537 * tahoe-pinsn.c: #include "tahoe-opcode.h", not "opcode.h".
2538 * tm-tahoe.h (FIX_CALL_DUMMY): Ignore more parameters.
2539 * defs.h (const, volatile): Only define if not already defined.
2540 * Makefile.dist (gdb.tar.Z): Create doc subdir w/out CVS/RCS crud.
2542 * README: Update for release 3.95.
2543 * config.gdb: Don't create readline dir in subdir builds.
2544 * main.c: Include with "..." form for non-system include files,
2545 so "gcc -MM" for "make depend" works.
2546 Include readline files with "...h" rather than <readline/...h>.
2547 * mipsread.c: Include "ecoff.h" rather than "intel-coff.h".
2549 * coffread.c: Undo minor damage done by Rich Pixley. Use
2550 different internal and external representations of COFF
2551 data structures. Use new BFD routines for swapping them in and
2553 * symfile.c (free_named_symtabs): Avoid freeing file names that
2554 are null or empty. Old i960 tools seem to produce files that
2555 claim to have empty names, causing each successive file read
2556 to blow away the previous one.
2557 * sparc-xdep.c (deferred_stores): Repair minor damage by Rich.
2558 Move deferred_stores to top of file, but don't separate its
2559 #define's from its variable. Add commentary.
2560 * Makefile.dist: Fix Rich damage; undo "configure" changes in
2561 favor of keeping the (working) config.gdb. Move readline
2564 Fri May 17 12:49:56 1991 Per Bothner (via gnu at cygint.cygnus.com)
2566 * dbxread.c (read_struct_type): Try to handle g++ version 1 MI
2568 * infptrace.c (fetch_registers): no result, since now void.
2569 * tconfig/news: target depends on m68k-tdep too.
2571 Fri May 17 14:40:14 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
2573 * Makefile.dist: added readline/inc-*.texinfo to dependencies for
2576 * readline/inc-history.texinfo, readline/inc-readline.texinfo:
2577 applied various small fixes due to or inspired by RMS comments
2579 * doc/gdb.texinfo: finished using all RMS comments, save those for
2580 appendices on readline and cmd history (which are in other source
2583 Thu May 16 18:06:05 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
2585 * doc/gdb.texinfo: (1) Updated w/ref to RMS comments through
2586 chapter 9; (2) documented 'break' command's menu mode for
2587 overloaded names, in response to hgs problem report C++ p-31
2589 Wed May 15 11:02:48 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
2591 * doc/gdb.texinfo: (1) better introductory example; (2) more
2592 consistent use of @code, @samp, @file, @kbd throughout; small
2593 cleanups to first three nodes; (3) new "Contributors" node;
2594 (4) Appendix, Renamed Commands; (5) divert specialized startup
2595 instructions to "Targets" chapter for generic manuals, while
2596 leaving them up front for manuals specific to specialized
2597 environments; (6) apply fixes from RMS comments through chapter 4.
2599 * pretex.m4: modify explanatory text slightly (and redefine
2600 "regexp") to keep GNU m4 from complaining. (It still crashes
2601 later, but one step at a time...)
2603 Wed May 15 10:32:12 1991 John Gilmore (gnu at cygint.cygnus.com)
2605 * readline/readline.c (update_line): Avoid dereferencing a pointer
2606 before comparing it to its bounds. Saber caught this.
2607 (init_terminal_io): Don't set BC from the "pc=" termcap variable,
2608 and only set PC if tgetstr returned non-null. Saber caught this.
2610 Tue May 14 16:29:53 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)
2612 * Makefile.dist: put gdb.dvi stuff (updated to use M4 preprocessor
2613 stuff for config manual) here where it counts; updated
2614 to use new subdir structure (gdb/doc/).
2616 * Makefile: generated from above via
2620 * gdbint.texinfo: added instructions on generating gdb.info* files
2621 locally for release. These are ordinary info
2622 files, formatted from gdb.texinfo (via gdb-all.texinfo, see
2623 Makefile)---but due to use of texinfo 2, can't count on makeinfo
2624 to generate these, so we distribute them already formatted.
2626 * gdb.texinfo: included full Info node and menu crud (as generated
2627 by C-u M-x texinfo-master-menu using the texinfo-2 elisp code).
2629 * Makefile: updated "gdb.dvi" target to use M4 preprocessor;
2630 put in comments-for-future gdb.info target (one day makeinfo will
2633 Tue May 14 13:51:36 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)
2635 * gdb.texinfo: Updated to include new or old undocumented
2636 commands, at least the following (perhaps some others I forgot to
2637 record): info f, info float, info path, info program, info s, info
2638 set, info source, info terminal, info types, info user, set/show
2640 Also covered all recent GDB command renames for v4.
2642 Mon May 13 14:57:46 1991 John Gilmore (gnu at cygint.cygnus.com)
2644 * mipsread.c: Rather than keeping count of how many symtabs
2645 and psymtabs we have, for sorting purposes, count them when
2646 we need to sort. This fixes bug in rereading of symbol tables.
2648 Fri May 10 15:43:33 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)
2650 * infcmd.c: renamed "info path" to "show paths"

2664 * coffread.c, exec.c, infptrace.c, inftarg.c, remote.c, solib.c,
2665 symtab.h, target.c, target.h: Lint.
2666 * core.c: setup and select frame after reading shared libs,
2667 else reading shared libs will clobber them. Lint.
2668 * utils.c (error): Force out any buffered wrap text.
2670 Fri May 3 22:01:56 1991 John Gilmore (gnu at cygint.cygnus.com)
2672 * remote.c: Remove decls of memory_insert_breakpoint
2673 and memory_remove_breakpoint, no longer used. (Suggestion of
2676 * Makefile.dist: use ${subdir} in paths of BFD and LIBIBERTY,
2677 to make it easier to interface to "configure"'d libraries.
2679 Fri May 3 13:10:01 PDT 1991 Roland Pesch (pesch at fowanton.cygnus.com)
2681 * valprint.c: introduce "set p", "set pr", "show p" and "show pr" as
2682 aliases for set/show print.

2738 * coffread.c [TDESC]: Move setting of debug_info from
2739 coff_symfile_read to find_linenos and make it work with BFD.
2741 * cplus-dem.c [__STDC__]: Make x{m,re}alloc return void*.
2743 * signame.c: Cast const char* to char* when assigning to sys_siglist.
2745 * utils.c (strsave): Make arg const char* not char*.
2747 * infrun.c (wait_for_inferior) [SHIFT_INSN_REGS]: Use

2768 Mips bringup and general cleanup
2770 * cplus-dem.c: Move CPLUS_MARKER define to after defs.h.
2771 * infptrace.c (PT_WRITE_D, PT_READ_D): Use correct values.
2772 (This still doesn't seem to make MIPS bkpts work.)

2774 (symbol_file_command, add_file_command): Remove, obsol.
2775 * printcmd.c (ptype_command): Say "an enum" rather than "a enum".
2776 Wrap output appropriately.
2777 * stack.c (locals_info, catch_info, args_info): Check
2778 selected_frame rather than target_has_stack or coredumping.
2779 * valprint.c (type_print_varspec_suffix): Wrap "ptype" output of
2780 enums appropriately.
2782 Wed May 1 14:10:22 1991 Jim Kingdon (kingdon at cygint.cygnus.com)

2791 can have both ints and enum type_pieces in it.
2792 ({push,pop}_type_int): New functions.

2807 copying.awk, solib.c, inflow.c, symmisc.c
2808 : Lint. Use read_memory not read_memory_integer on CORE_ADDR's.
2809 Use {value_as,unpack}_pointer (added to values.c)
2810 not {value_as,unpack}_long on CORE_ADDR's.
2811 Use longest_to_int (added to defs.h) instead of cast to int.
2812 Remove from_tty arg to mod_path.
2813 Put symfile_bfd in {coff,dbx}read.c not symfile.h.
2814 Use OP_NULL instead of 0 where dummy enum exp_opcode needed.

2857 * param-no-tm.h: Make BITS_BIG_ENDIAN defined to 0/1, not defined
2858 or not defined. Don't define it based on TARGET_BYTE_ORDER if

2861 values.c (modify_field, unpack_field_as_long):

2865 Fri Apr 26 12:02:06 1991 Jim Kingdon (kingdon at cygint.cygnus.com)
2867 * tm-sparc.h: Add comments about gcc version 2 and structure passing.
2869 * xconfig/i386v{,32}{,-g}: Add XM_CFLAGS=-Dgetpagesize()=4096.
2870 gmalloc.c: #if 0 out !HAVE_GETPAGESIZE code.
2872 * expread.y (abs_decl): Accept '&' and '&' abs_decl.

2883 Wed Apr 24 09:45:17 1991 Jim Kingdon (kingdon at cygint.cygnus.com)
2884 Changes from Tiemann:
2885 * cplus-dem.c (optable): Add "nw", "dl", "compound".
2886 (cplus_mangle_opname): New function.
2887 (do_type): Add case 'Q'.
2888 * values.c (check_stub_method): Do lookup_method_type and stuff
2889 rather than smash_to_method_type.
2890 symtab.c, symtab.h (allocate_stub_method): New function.
2891 dbxread.c (read_type): If we get "##", don't lookup_function_type

3287 (set_section_command): New command ("section xxx yyy" -- should
3288 be renamed to "set section xxx yyy" FIXME) which sets the

3299 * tm-i386v.h (FLOAT_INFO): Don't define it, since the code

3302 * i386-pinsn.c: Move #includes to top, remove useless ones.
3303 * i386-tdep.c: Don't bother including <.../reg.h> since we

3320 current frame in the core file, if we have one.

3350 * dbxread.c (really_free_pendings): Clear file_symbols
3351 and global_symbols after freeing them; otherwise, running

3356 based on text_addr (the address of text in core), not on addr (the
3357 offset between text in the .o file and in core). This change
3358 is from Peter Schauer.
3360 * main.c: Define ALL_CLEANUPS as a cast of zero.
3361 (return_to_top_level): Use it.
3362 (main): Do all cleanups after each command run as part
3363 of the gdb startup sequence. Also do all cleanups before
3364 entering the command loop, and every time we exit the command
3365 loop and reenter. Before, the cleanups from the startup sequence
3366 were being left undone until the first error!
3367 (command_loop): Rename do_nothing cleanup to command_loop_marker
3368 so we can see it easily when examining the cleanup chain.
3369 (init_signals): Add another do_nothing for signal handling.
3370 (quit_command): Only try to kill target if it has execution.
3371 Problems in the target stack got us into a state where
3372 inferior_pid was nonzero but none of the targets had execution.
3373 In this state you couldn't exit gdb.
3375 * dbxread.c: Two changes from Peter Schauer.
3376 (echo_command): Fflush output after an echo command.
3377 (show_history): Pass all args to cmd_show_list.
3379 * utils.c (init_malloc): Call mtrace to turn on tracing
3380 if the environment variable MALLOC_TRACE is set to a file name.
3381 * mtrace.c: Add source file which provides a log of every malloc,
3382 free, and realloc to a trace file.
3383 * mtrace.awk: Add source file which analyzes the trace file.
3384 * Makefile.dist (GNU_MALLOC, MALLOCSRC): Add mtrace.{c,o,awk}.
3385 (VERSION): Roll to 3.94.3.
3387 * breakpoint.c (breakpoint_1): Add a space to "i watch" output.
3388 (check_duplicates): Don't bother with watchpoints.
3389 (set_raw_breakpoint): Comment about danger of this routine.
3390 (watch_command): Parse and eval all args before calling
3393 * solib.c (find_solib): Avoid error in referencing memory to
3394 see if any more shared libraries have been added. This is
3395 particularly useful if the target has terminated. Bug reported
3398 Changes from Peter Schauer <pesrem@regent.e-technik.tu-muenchen.de>
3399 in bringing up 3.94.2 on the Sun-3.
3401 * Makefile.dist: Include CFLAGS in rule for cplus-dem.o.
3402 * breakpoint.c (enable_breakpoint): Check for valid watchpoint
3403 expression (in scope) before reenabling watchpoint.
3404 * signame.c (init_sigs): Add missing declaration of i, fix
3405 sys_siglist declaration.
3406 * source.c (list_command): Fixed range computation to use
3408 * stack.c (backtrace_command): Do not allow command if target has
3409 no stack, print informative error message.
3410 * target.c (target_command): Do not write into command line
3411 because this fails if the target command is used in a user defined
3412 command. [This change was enhanced by gnu to support any-
3413 unique-prefix matching on target names.]
3414 * valops.c (value_struct_elt): Avoid infinite loop on an
3415 erroneous attempt to print the member of function (try p main.p).
3417 Mon Apr 1 17:05:45 1991 John Gilmore (gnu at cygint.cygnus.com)
3419 * expread.y (name_no_typename): Avoid reduce/reduce errors
3420 caused by ambiguity in handling NAME_OR_INT and NAME_OR_UINT.
3421 Since the GDB parser really doesn't use name_no_typename in a
3422 name-only context, the parser can't tell the diff between
3423 names and numbers here. Avoid allowing a name_no_typename
3424 to be a NAME_OR_*INT to resolve the conflict.
3426 Sun Mar 31 20:12:07 1991 John Gilmore (gnu at cygint.cygnus.com)
3428 Bugfixes from Mark Fox (markf@wrs.com) (test=testField.c):
3430 * valprint.c (val_print_fields): bitfield printing didn't handle
3431 byte order. Indirect through a few more fns to cope.
3433 * values.c (modify_field): also cope with byte order.
3435 Sat Mar 23 10:02:21 1991 John Gilmore (gnu at cygint.cygnus.com)
3437 Cleanup for release 3.94.2:
3439 * Makefile.dist: Pull REMOTE_OBS. Fix saber includes for BFD
3440 include files. Roll version to 3.94.2.
3442 * coffread.c (init_stringtab): Read length into unsigned char
3443 array before swapping; don't assume 32-bit longs.
3445 * target.c (target_info): Don't bother with get_sym_file, just use
3446 the symfile global variable.
3447 * symtab.h, symfile.c (get_sym_file): Delete it.
3449 * dbxread.c (dbx_symfile_init): Don't depend on long == 4 bytes.
3450 (define_symbol): Set symbol line number to 0 if not gcc-compiled.
3451 (read_type): Replace one more error() with complain().
3453 * mipsread.c (parse_partial_symbols): Replace printf with complain.
3455 * i960-tdep.c: Fix copyright attribution.
3457 * config.gdb: Quote all backquotes in doublequotes. You can
3458 quote me on that. BSD 4.4 shell found this one.
3460 * infptrace.c (throughout): The third argument to ptrace is an
3463 * infrun.c (wait_for_inferior): When program has terminated, we
3464 have to call target_terminal_ours before we pop that target off
3465 the stack (e.g. before a call to target_kill or
3466 target_mourn_inferior). This fixes problem where a program
3467 terminates, then GDB stops for (tty output) and you have to type
3468 "fg" to the shell to resume it. FIXME: This code for what to
3469 do after termination really should be in normal_stop instead.
3471 * gdbcore.h (read_memory_check): Change declaration; it changed
3474 * terminal.h: Include <sgtty.h> before <sys/ioctl.h>, since in BSD
3475 4.4 prereleases, this avoids a bug in their sgtty compatability
3477 * remote.c: Use terminal.h rather than hand-rolling the same.
3479 * signame.c, signame.h (psignal): Arg is unsigned, not int.
3480 * utils.c (strsave, strstr): Fix arg types.
3481 * valprint.c (val_print): lint
3483 MIPS symbol table support from Per Bothner:
3485 * symfile.c (symtab_fns): Remove initializer table that needs to
3486 be hacked for each new symbol file format supported.
3487 (add_symtab_fns): New function, chains symbol table
3488 handlers into the global list.
3489 (symfile_init): Search this list.
3490 * symfile.h: Add next pointer, declare add_symtab_fns.
3491 * coffread.c (_initialize_coffread): Call add_symtab_fns.
3492 * dbxread.c (_initialize_dbxread): Call add_symtab_fns.
3494 * mipsread.c (psymtab_to_symtab_1): return void instead of (struct
3495 symbol *). Thus, we no longer need the hack to trash
3496 pst->filename. Good, since that hack confused code in symfile.c!
3498 (reorder_symtabs, destroy_all_symtabs): Removed static
3499 all_symtabs, which was used to qsort symtabs in reorder_symtabs.
3500 Instead, the latter now uses a temporary array (stack-allocated
3501 from an obstack, and then freed).
3503 (parse_symbol): Added a hack to fix up BLOCK_{START,END} if they
3504 haven't been set in the outermost stBlock of a procedure. This was
3505 a problem with f77 binaries on Ultrix 4.?.
3507 (new_symtab, new_symbol, new_type): Continue changing code to use
3508 obstacks more and otherwise conform to dbxread internal style.
3509 Made the free_code of symtabs be free_linetable (as in dbxread)
3510 instead of free_contents. This implies memory leaks when reading
3511 a new symbol table, until the conversion is finished. Did change
3512 (struct symbol) and (struct type) to be allocated on the
3513 symbol_obstack. Blocks and blockvectors are among the things
3516 * mipsread.c (parse_partial_symbols, parse_fdr): It hasn't been
3517 tested much, but it solved one problem (reported by Meissner), and
3518 cleans up some other things. The problem happened when an
3519 included file contains actual code (functions) and not just
3520 definitions. The mips coff is a little inconvenient there, since
3521 it may cause a procedure to be mapped to the wrong psymtab.
3523 * mips-tdep.c (heuristic_proc_desc): Minor cleanup.
3524 * mips-xdep.c (fetch_core_registers): Minor cleanup. FIXME,
3525 this will need work for the new core paradigm.
3527 Opcode patches from the net:
3529 * mips-opcode.h: fix incorrect disassembly of the mfc1, cfc1, and
3530 ctc1 instructions. Also, the cvt.d.w and cvt.s.w instructions were
3531 missing altogether - they are added here. From Bruce Bauman.
3532 * mips-opcode.h: The low mask for C0 instructions was too small.
3533 From Garrett Lau. I modified the fix to check the entire 32-bit
3536 * ns32k-opcode.h: Fix opcodes for deiw and deid. From Bruce
3539 Thu Mar 21 12:56:46 1991 John Gilmore (gnu at cygint.cygnus.com)
3541 Roll in changes from Per Bothner (Tue, 25 Sep 90 11:11:04):
3543 * dbxread.c (read_type): Pointer subtraction (value_sub in
3544 valarith.c) sometimes failed because the types of the
3545 pointers being subtracted were not identical.
3546 These differed because dbxread.c was allocating pointer types
3547 using dbx_alloc_type+smash_to_pointer_type instead of
3548 lookup_pointer_type. I failed to find a justification for the
3549 former, so I changed it to use the latter. Similarly, I
3550 replaced smash_to_function_type by lookup_function_type,
3551 and smash_to_reference_type by lookup_reference_type.
3553 * mipsread.c (parse_symbol, upgrade_type, parse_procedure,
3554 _initialize_mipsread): corresponding changes.
3556 * symtab.c (smash_to_{pointer,reference,function}_type): eliminate.
3558 * source.c (mod_path): Do tilde_expand on each component of the path,
3559 rather than on the (list of) paths as a whole.
3560 (print_source_lines): Set first_line_listed in addition to
3561 current_source_symtab and current_source_line. If the source was
3562 not findable, after a "dir" command to fix the problem,
3563 a "list" would get the wrong lines.
3565 While I was there... (gnu):
3567 * dbxread.c (read_type): Change error to complaint.
3569 Thu Mar 21 12:56:46 1991 John Gilmore (gnu at cygint.cygnus.com)
3571 First attempt at detailed understanding of symbol table memory alloc.
3573 * dbxread.c (dbx_symfile_read): Free our string table if we
3574 aren't the mainline. Free the "info" struct since we're done with
3576 (init_psymbol_list): Free any previously allocated psymbol lists.
3577 (): FIXME: Should realloc-down the psymbol lists when done reading
3578 the main symbol file?
3580 * symmisc.c (free_symtab): Free fullname field too.
3582 * xm-hp300hpux.h (USG): #undef then #define so Makefile can -D.
3583 (REGISTER_ADDR): Make result type unsigned int.
3585 * xconfig/{i386*,hp300hpux,altosgas,altos}: All config files that
3586 define REGEX must also define REGEX1 (its dependency).
3588 Tue Mar 19 21:28:57 1991 John Gilmore (gnu at cygint.cygnus.com)
3590 * tconfig/i960: No longer works, points you at vxworks960 or
3593 * xgdb.c, XGDB-README: Remove file. Users can get the much
3595 * Makefile.dist: Remove all trace of xgdb.
3597 * breakpoint.c (breakpoint_1): Pass demangle arg to
3598 print_address_symbolic.
3599 (clear_breakpoints): Remove unused function.
3600 (breakpoint_re_set_one): Guts of breakpoint_re_set.
3601 (breakpoint_re_set): Use catch_errors to do them all anyway.
3603 * gdb-int.texinfo (Host versus Target): Add section on what is
3604 a "host" feature versus what is a "target" feature.
3606 * infcmd.c (path_command, path_info): Handle the PATH variable
3607 (object search path) as conveniently as the source search path.
3608 * environ.c (set_in_environ): Set some vars in GDB's environment,
3609 in addition to the child's. PATH, G960BASE, G960BIN for starters.
3610 * source.c (mod_path): New function, from guts of
3611 directory_command, modifies a path. Used by path_command.
3612 (directory_command): Call it.
3613 * defs.h (strsave): Declare.
3615 * utils.c (sevenbit_strings): Add new printing option.
3616 (printchar): Use it.
3617 (strsave): Provide this handy helper routine.
3618 (set_width_command): Rename set_screen_width_command.
3619 (_initialize_utils): "set screen-width" => "set width";
3620 "set screen-height" => "set height"; add sevenbit-strings.
3622 * infcmd.c (do_registers_info): Print floating point registers
3623 in raw hex as well as float format, regardless of whether it is
3624 a "virtual" convertible register.
3625 * tm-sparc.h (PRINT_REGISTER_HOOK): Print every pair of float
3626 regs as a double, just in case it's being used that way.
3627 * values.c (unpack_long): Comment on array/function coercion.
3628 (unpack_double): Argument is in target byte order now. For
3629 integer arguments, just call unpack_long and float the result.
3630 * m68k-tdep.c: include defs.h for "const" handling.
3631 * remote-nindy.c: Use ieee-float stuff.
3632 (nindy_fetch_registers): Unpack double regs to host double, then
3634 (nindy_store_registers): Pack extendeds to host double, flip
3635 around by misusing unpack_double, send as target double.
3637 * tm-vxworks68.h (FRAME_CHAIN): Handle current frame pointer of
3638 zero, as when stopped at the first instruction of a process.
3640 * blockframe.c: Fix filename in comment (param.h => tm.h).
3641 * sparc-tdep.c (skip_prologue): More explicit nudging comments.
3642 * tm-68k.h: Fix typos.
3644 Fri Mar 15 01:09:34 1991 John Gilmore (gnu at cygint.cygnus.com)
3646 Changes from a bringup on the DEC Vax under Ultrix 4.0.
3648 * coredep.c (fetch_core_registers): Pass end-address of register
3649 section to register_addr as expected. Don't call supply_register
3650 if we'd just pass it garbage.
3652 * dbxread.c (read_dbx_symtab): Skip N_NSYMS on Ultrix.
3654 * exec.c (xfer_memory): Use boolean xfer_fn result, not int.
3656 * target.c (push_target, target_info): Cast enums to int for < or
3659 * stack.c (print_frame_info): Identify source file & line
3660 even if we can't print it.
3662 * xm-vax.h (MISSING_VPRINTF): No longer missing in Ultrix V4.0.
3664 Sat Mar 9 10:08:20 1991 John Gilmore (gnu at cygint.cygnus.com)
3666 Clean up IEEE floating point support.
3668 * ieee-float.h: New file.
3669 * ieee-float.c: Write real routines to convert between host
3670 doubles and various target IEEE extendeds.
3671 * m68k-xdep.c: Eliminate assembler code for extended floats.
3672 * xconfig/{3b1,altos,altosgas,hp300bsd,isi,news,news1000,sun2os3,
3673 sun2os4,sun3,sun3os3,sun3os4}: Eliminate use of m68k-xdep.o.
3674 * tm-i960.h, tm-68k.h (REGISTER_CONVERT_TO_VIRTUAL,
3675 REGISTER_CONVERT_TO_RAW): Use ieee_extended_to_double and
3676 double_to_ieee_extended.
3677 * i960-tdep.c: Define ext_format_i960.
3678 * m68k-tdep.c: Define ext_format_68881.
3679 * sparc-tdep.c: Define ext_format_sparc, though unused.
3680 * Makefile.dist (HFILES): Add ieee-float.h.
3681 * inftarg.c: #include "ieee-float.h" for the REGISTER_CONVERT
3684 Obsolete the "coffstrip" program in favor of using BFD's strip.
3686 * nindy-share/coffstrip.c: Remove file.
3687 * nindy-share/nindy.c (coffstrip): Routine to run bfd_strip.
3688 * Makefile.dist: Remove references to nindy-share/coffstrip.c.
3689 * tconfig/nindy960: Remove reference to coffstrip.o.
3691 * Makefile.dist: Roll version number to 3.94.1 (not yet final).
3693 Wed Mar 6 09:56:45 1991 John Gilmore (gnu at cygint.cygnus.com)
3695 * symfile.h: Add symfile_bfd, common between dbxread and coffread.
3696 * dbxread.c: Remove static symfile_bfd.
3697 * infcmd.c (do_registers_info): Add PRINT_REGISTER_HOOK, though
3699 * inftarg.c (child_detach): Pop the child_ops vector if the
3700 detach is successful.
3701 * remote-nindy.c (nindy_create_inferior): Don't push a new
3702 nindy_ops since nindy uses the same one for execution and memory
3704 * core.c (core_ops): Use child_attach and child_create_inferior
3705 rather than default attach and create_inferior functions.
3707 Handle floating point registers in core files.
3709 * sparc-xdep.c (fetch_core_registers): Rewrite for float support.
3710 * sun3-xdep.c (fetch_core_registers): Rewrite for float support.
3711 This version untested since BFD doesn't yet support sun3 core
3713 * hp300hpux-xdep.c: Rewrite fetch_core_registers to new calling
3714 conventions. Fix comments and style. This version has not
3715 been compiled yet, since we have no HP inhouse.
3716 * core.c (get_core_registers): Look for two sections, ".reg"
3717 and ".reg2", and pass both to fetch_core_registers sequentially.
3719 Revise directory path yet again.
3721 * source.c (forget_cached_source_info): Not static any more.
3722 (init_source_path): New default source path is "$cdir:$cwd".
3723 (dir_command): Handle variable arguments ($cdir, $cwd).
3724 (source_info): Print "Compilation directory" rather than
3725 "Originally compiled in" to remind people of $cdir.
3726 (openp): If the path contains $cwd, use current directory.
3727 (open_source_file): If compilation directory is known, replace
3728 first $cdir in path with the compilation directory.
3729 (print_source_lines): Even if we can't print the lines, set the
3730 current symtab and line for future commands like "info source" or
3731 "breakpoint". Also, error message now contains the file name,
3732 line number, and file access error message.
3733 (_initialize_source): Fix help text to describe changes.
3734 * main.c (cd_command): Forget cached source info when we chdir.
3735 * utils.c (strstr): Add simple implementation.
3737 Tue Mar 5 01:41:40 1991 John Gilmore (gnu at fowanton.cygnus.com)
3739 * coffread.c (read_one_sym, init_linetable, init_stringtab):
3740 Byte-swap COFF symbol tables if necessary when reading them in.
3741 Use complain() to replace error message in one spot. Needs
3742 corresponding change in bfd/coff-code.h to make some symbol
3743 swapping routines non-static.
3745 Mon Mar 4 00:53:40 1991 John Gilmore (gnu at cygint.cygnus.com)
3747 Merge changes from Eirik Fuller, for UTek.
3749 * defs.h (errno): Add declaration.
3750 * altos-xdep.c, arm-xdep.c, convex-xdep.c, gould-xdep.c,
3751 hp300hpux-xdep.c, infrun.c, inflow.c, infptrace.c, i386-tdep.c,
3752 i386-xdep.c, pyr-xdep.c, mips-xdep.c, remote-eb.c, remote-nindy.c,
3753 remote-vx.c, source.c, standalone.c, stuff.c, sun386-xdep.c,
3754 symmetry-tdep.c, symmetry-xdep.c, umax-xdep.c, utils.c: Eliminate
3755 declarations of errno.
3757 * remote-eb.c: Define B19200 and B38400 as EXTA and EXTB.
3759 * remote-vx.c: Include <sys/time.h> for UTek; Sun gets it via
3760 <rpc/rpc.h> and <rpc/types.h>.
3762 Sat Mar 2 15:47:55 1991 John Gilmore (gnu at cygint.cygnus.com)
3764 * i960-tdep.c (examine_prologue): Add new argument limit,
3765 which stops the scan at the end of the prologue, or at the PC.
3766 This fixes a problem where it walks down into the code for the
3767 user's statements if that code looks like function prologues.
3768 Mark Fox and I have been bouncing this code back and forth, making
3769 small changes to it. Callers changed to match.
3771 Tue Feb 26 01:47:07 1991 Cygnus John Gilmore (cygnus at yuba)
3773 Cleanup for gdb-3.94 release final:
3775 * Makefile.dist: Remove remote-vx.c, remote-nindy.c, and all
3776 the .c files from vx-share and nindy-share, from the various
3777 macros, since they are not found via ALLDEPFILES.
3778 (SFILES): Add tm-i960.h.
3779 (alldeps.mak rule): Break out ALLDEPFILES_MAINDIR and
3780 ALLDEPFILES_SUBDIR. List all the nindy and vxworks subdir files
3782 (TAGFILES_MAINDIR): Change ALLDEPFILES to ALLDEPFILES_MAINDIR.
3783 (gdb.tar.Z): Use ALLDEPFILES_SUBDIR as well as SFILES_SUBDIR.
3785 Mon Feb 25 16:02:35 1991 Cygnus John Gilmore (cygnus at oldman)
3787 * am29k-tdep.c: Add contribution line.
3788 (examine_prologue): Cache information about function prologues in
3789 the misc-function-vector to avoid lots of references over the
3790 serial line while examining instructions.
3792 * core.c (core_close): New function made from cleanup_core.
3794 * core.c, exec.c, inftarg.c, remote-eb.c, remote-nindy.c,
3795 remote-vx.c, remote.c, target.c, target.h,
3796 Update target_ops vector to add attach, close, and load entries.
3797 Use add_syms_addr_command, not add_file_addr_command, for
3798 add_file. Break out close routine from existing code.
3800 * dbxread.c (really_free_pendings): Don't free pending_blocks;
3801 they are in an obstack.
3802 (read_dbx_symtab): Relocate end_of_text_addr in the psymtab.
3804 (define_symbol): Add symbol type parameter; change callers;
3805 pass type parameter to DBX_PARM_SYMBOL_CLASS macro to allow
3806 it to influence the symbol class on the i960.
3807 (define_symbol): Swap LOC_CONST's into target byte order.
3809 * exec.c (exec_close): New function.
3810 (exec_file_command): Call it.
3812 * findvar.c (read_relative_register_raw_bytes): Doc byte order,
3813 Fix byte order of frame pointer.
3814 (read_var_value): Result of 0 if var's value can't be found,
3815 e.g. missing FRAME_ARGS_ADDRESS. Byte-swap LOC_CONST and
3816 LOC_LABEL values to target order. Add LOC_LOCAL_ARG.
3817 (locate_var_value): Use read_var_value and use its lazy address
3818 as the location of the var's value. Lint.
3820 * i960-pinsn.c (next_insn): Add routine from vxgdb for scanning
3823 * i960-tdep.c (arg_address, i960_frame_find_saved_regs): Remove
3824 obsolete Intel versions in favor of vxgdb versions.
3825 (check_host, byteswap, byteswap_val, reorder_val): Eliminate
3826 code dealing with byte order of values, which Intel did in host byte
3827 order rather than gdb-4's target byte order.
3828 (i960_frame_chain_valid): Move to nindy-tdep.c.
3829 (examine_prologue, skip_prologue, frame_find_saved_regs,
3830 frame_args_address, leafproc_return, saved_pc_after_call,
3831 pop_frame): Add vxgdb versions from Mark Fox.
3832 (examine_prologue, frame_struct_result_address): Add code
3833 to deal with the saved value of G13 (struct return address
3835 (frame_args_address): Modify Mark's version to prefer the
3836 saved value over the current value in the topmost frame.
3837 Cache result in the frame info to avoid performance hair in
3839 (print_fault): Add gdb960 code for printing faults.
3840 (_initialize_i960): Actually call check_host.
3842 * ieee-float.c (ieee_extended_to_double, ieee_double_to_extended):
3843 add stub routines. FIXME, these currently just return zero!
3845 * infcmd.c (program_info): Use PRINT_RANDOM_SIGNAL.
3846 (attach_command): Call target_attach, not target_open, now.
3848 * infrun.c (normal_stop): Make global, not static, for vx_attach.
3849 (child_attach): Rename from child_open.
3850 (wait_for_inferior): Use PRINT_RANDOM_SIGNAL. If stop_pc is zero,
3851 don't confuse it with a zero step_resume_break_address.
3853 * inftarg.c (child_detach): Eliminate inferior_pid test.
3854 (child_files_info): Clean up message a bit.
3855 (child_ops): Use child_attach, not child_open, to attach.
3857 * mem-break.c: #ifdef out the whole file if BREAKPOINT is not
3858 set (e.g. on VxWorks or NINDY). Move read_memory_nobpt from
3859 findvar.c to here, since it depends on the contents of the
3860 shadow_contents of breakpoints, but keep if #if 0 since it is
3863 * nindy-tdep.c: New file, contains nindy_frame_chain_valid, moved
3866 * printcmd.c (address_info): Handle LOC_LOCAL_ARG. Lint.
3867 (ptype_command, display_command): Eliminate have_inferior_p and
3868 have_core_file_p in favor of target_has_stack or
3869 target_has_execution.
3870 (print_frame_args): Handle LOC_LOCAL_ARG. Eliminate duplicate
3871 code for actually finding the values of arguments, though we still
3872 keep track of the maximum stack offset for use in printing unnamed
3873 arguments. Handle missing FRAME_ARGS_ADDRESS.
3875 * remote-nindy.c (i960_print_fault): Move to i960-tdep.c.
3876 (struct nindy_regs): Define registers passed to/from nindy.
3877 (nindy_fetch_registers, nindy_store-registers): Translate between
3878 nindy and GDB formats for the registers.
3879 (dcache_init): Statically allocate the cache, since it was being
3880 allocated by a malloc that was never freed anyway.
3881 (nindy_create_inferior): Error, not core dump, if no exec file.
3882 (nindy_before_main_loop): Use target_load, not target_add_file.
3884 * remote-vx.c (net_load): Specify large timeout for load
3885 requests. Allow user to break out with INTERRUPT.
3886 (net_break): Remove useless code, clean up. Change callers.
3887 (parse-args, skip_white_space, find_white_space): Clean up arg
3888 parsing to cope with quoted strings.
3889 (net_wait, net_quit): Never call error, just return status.
3890 (vx_read_register, vx_write_register): Cleanup status checking.
3891 #ifdef the code based on which CPU we are using (960 or 68k),
3892 FIXME, this should be completely general but it isn't yet.
3893 (vx_xfer_memory, vx_resume): Cleanup status checking.
3894 (vx_run_files_info): Improve message.
3895 (vx_load_command): Renamed from vx_add_file_command. Allow load
3897 (net_ptrace): Remove unused routine.
3898 (vx_wait): Adopt code from vxgdb960 to cope with broken
3899 connections to target machine and prompt to disconnect. Remove
3900 debug printouts. Map some EVENT_'s to SIGnals.
3901 (add_symbol_stub, vx_open): Print names of object files we found,
3902 and "ok" if we read their symbols OK. Clarify output in general.
3903 (vx_attach, vx_detach, vx_kill): Add these commands.
3904 (vx_convert_from_virtual, vx_convert_to_virtual): Simplify.
3905 (vx_run_ops): Turn off all_mem, to avoid spurious msg in the
3906 "info files" output, and create_inferior, since we already have
3909 * stack.c (frame_info): Replace Frame_unknown with 0.
3910 (print_frame_arg_vars): Handle LOC_LOCAL_ARG.
3911 (return_command): Pop until the PC matches as well as the FP,
3912 so it works even if the FP is shared with another function,
3913 as in "frameless" or "leaf" procedures.
3915 * symfile.c (load_command): renamed from add_file_target_command.
3916 (add_syms_addr_command): renamed from add_file_addr_command.
3917 (add_syms_command): Stub to call target_add_syms.
3918 (_initialize_symfile): Change command names and descriptions,
3919 add-file => add-syms, and load from alias to its own command.
3921 * target.c (kill_or_be_killed, maybe_kill_then_attach,
3922 maybe_kill_then_create_inferior): Default for attempts to start
3923 a process, if one is already running, is to ask about killing
3924 it and retry if yes.
3925 (upstack_create_inferior): #if-0 it, strata obsolete it.
3926 (push_target, unpush_target, pop_target): to_close() a target
3927 before unstacking it.
3928 (target_info): Renamed from target_files_info.
3929 (_initialize_targets): Rename "i files" as "i target", accessible
3932 * target.h: Improve comments about the target_ vectored routines.
3934 * tm-i960.h: Remove NINDY-specific stuff to tm-nindy960.h.
3935 Convert commenting style to standard GNU style.
3936 (DBX_PARM_SYMBOL_CLASS): allow LOC_LOCAL_ARG's to be recognized.
3937 (SKIP_PROLOGUE): No longer a no-op.
3938 (SAVED_PC_AFTER_CALL): Now handles leaf procedures.
3939 (*_REGNUM): Sort register numbers.
3940 (REGISTER_BYTES, REGISTER_BYTE, REGISTER_RAW_SIZE,
3941 MAX_REGISTER_RAW_SIZE, REGISTER_CONVERTIBLE,
3942 REGISTER_CONVERT_TO_VIRTUAL, REGISTER_CONVERT_TO_RAW): Float regs
3943 are now 10 byte extendeds, not 8 byte doubles.
3944 (FRAME_CHAIN_VALID): Make this config-dependent, since it differs
3945 for nindy versus vxworks targets. FIXME, this should possibly go
3946 in the target vector.
3947 (EXTRA_FRAME_INFO, INIT_EXTRA_FRAME_INFO): Cache both
3948 frame_saved_regs and arg pointer with each frame.
3949 (FRAMELESS_FUNCTION_INVOCATION): New leafproc support.
3950 (FRAME_ARGS_ADDRESS): Use cached result.
3951 (FRAME_ARGS_ADDRESS_CORRECT): New, avoids g14 guessing.
3952 (FRAME_FIND_SAVED_REGS): Change arg to subsidiary fn.
3953 (PRINT_RAMDON_SIGNAL): Call print_fault.
3954 (POP_FRAME): Now works.
3956 * tm-nindy960.h: Break this off tm-i960.h. NINDY-specific
3957 option parsing and startup; STACK_END_ADDR, FRAME_CHAIN_VALID,
3958 BREAKPOINT, and DECR_PC_AFTER_BREAK are here.
3959 (ADDITIONAL_OPTION_HANDLER): use target_load, not
3962 * tm-vxworks960.h: Break this off tm-i960.h. VxGDB specific
3963 startup; DECR_PC_AFTER_BREAK, and FRAME_CHAIN_VALID are here.
3965 * valarith.c (value_subscripted_rvalue): Avoid handling
3966 floats and doubles specially; it gave alignment errors. Lint.
3968 * valops.c (value_of_variable, value_of_this): Error if unknown
3971 * valprint.c (print_floating): Bcopy rather than pointer-deref,
3972 to avoid alignment problems.
3973 (value_print): Handle unknown value address.
3974 (cplus_val_print): Two args are ignored; remove them. Change caller.
3975 (val_print): Use unpack_long rather than pointer-deref.
3978 (unpack_long, unpack_double): Use bcopy rather than pointer-deref
3979 to avoid alignment problems.
3980 (value_being_returned): Error if return value unknown.
3981 (set_return_value): Add bogosity warning, FIXME. *
3983 * TODO: A woman's work is never done.
3985 * Makefile.dist: Distribute REMOTE_OBS into tconfig files.
3986 Separate INCLUDE_CFLAGS for use with lint. Add LINTFILES.
3987 Add ieee-float.o to OBS.
3988 * tconfig/{nindy960,vxworks68,vxworks960}: Include the desired
3989 REMOTE_OBS remote-interface files in the TDEPFILES and TM_FILE.
3990 * tconfig/i960: FIXME. Half-merge, produce warning if config'd.
3992 Changes to generalize the VxWorks RPC protocol slightly, to handle
3993 i960 as well as 68000.
3995 * vx-share/dbgRpcLib.h (VX_SOURCE_STEP): Add.
3996 * vx-share/reg.h: Produce i960 regs #ifdef I80960
3997 * vx-share/xdr_ptrace.c: Skip FPA registers if 960.
3998 * vx-share/xdr_rdb.h: Add SOURCE_STEP struct and xdr decl.
3999 * vx-share/xdr_rdb.c: Add xdr_SOURCE_STEP routine.
4000 * vx-share/xdr_regs.c: Add xdr_regs, xdr_fp_status, xdr_ext_fp
4001 for i960. Change xdr_vectors to xdr_opaques for 68k registers,
4002 so they will move in target byte order rather than network
4003 byte order (happens to be the same).
4005 Mon Feb 25 03:41:44 1991 John Gilmore (gnu at cygint.cygnus.com)
4007 * tm-convex.h (END_OF_TEXT_DEFAULT): Remove #if 0'd block.
4009 Sun Feb 24 00:55:53 1991 John Gilmore (gnu at cygint.cygnus.com)
4012 Add contribution lines to various files, showing where they
4015 * breakpoint.c (break_insn, check_break_insn_size,
4016 read_memory_nobpt): Remove to mem-break.c.
4018 * xm-*.h, param-no-tm.h, tm-29k.h, valprint.c: Change BYTE_ORDER to
4021 * tm-29k.h (STAB_REG_TO_REGNUM): Warn user if symbol table
4022 entry has bad register number. This change is not
4023 tested in this release, FIXME.
4025 * frame.h: Eliminate Frame_unknown in favor of a simple zero.
4028 * value.h: Force value's contents field to be aligned to hold
4029 at least a double or a long long (if supported). This avoids
4030 doing bcopy's in and out of the contents field.
4032 (step_1): Avoid coredump under obscure circumstances when we
4035 * symtab.h (misc_info): Add field to misc function vector for
4036 any kind of cached information the target code desires. AMD
4037 29000 uses this to avoid repeating examine_function_prologue's.
4039 * coffread.c: Lint. Remove static symfile, read_section_header.
4040 core.c (have_core_file_p): Lint: remove.
4041 expprint.c (print_subexp): Lint.
4042 infptrace.c, valops.c, valprint.c: lint.
4044 Roll in changes from vxgdb-5.0.1:
4046 * symtab.h: Comment byte order of each address class. Add
4047 LOC_LOCAL_ARG for frame-relative args (960).
4048 expread.y: Use LOC_LOCAL_ARG where LOC_ARG is used.
4049 symtab.c, symmisc.c: ditto.
4051 * infrun.c (init_wait_for_inferior): Clear stop_signal.
4053 * remote.c (remote_resume): Error if resume with a signal.
4055 * symfile.c (prim_record_misc_function): Clear misc_info.
4056 (fill_in_vptr_fieldno): Check stub type of arg.
4058 * valops.c (value_cast): Avoid looking up names of types whose
4059 name we don't know, to prevent coredump. Sun CC produces typedef
4060 rtx and the name of *rtx is zero...
4062 Mon Feb 18 21:16:25 1991 John Gilmore (gnu at cygint.cygnus.com)
4064 Roll in changes from final AMD 29000 port (Tiemann).
4066 tconfig/am29k: Add COFF_ENCAPSULATE and TARGET=TARGET_AM29K
4067 for ../include/a.out.encap.h. This might not work now that BFD
4068 is separately compiled. Instead, BFD support for encap will have
4069 to translate machine type 29k into the right COFF_MAGIC.
4071 * infcmd.c: Remove references to inferior_pid that aren't used
4072 in actual ptrace calls; use target_has_execution, etc.
4073 (have_inferior_p): Remove function.
4074 (program_info): Print target info rather than "process number";
4075 avoid gratuitous messages unless from_tty.
4076 (run_stack_dummy, finish_command): Set proceed_to_finish.
4077 infrun.c: Remove inferior_pid refs. Decl & init proceed_to_finish.
4078 main.c: Lint. Lose have_inferior_p().
4079 inferior.h (have_inferior_p): Remove, lint.
4080 (proceed_to_finish): Add flag to ask that all regs be saved
4081 by normal_stop, for the few commands that need it, speeding up
4082 serial I/O. Add comments to stop_registers.
4084 * remote-eb.c: Remove newline from breakpoint message we grep
4085 for. Never time out when running the user program.
4089 Wed Feb 13 15:34:40 1991 John Gilmore (gnu at cygint.cygnus.com)
4091 Roll in changes from vxgdb-5.0.1:
4093 * dbxread.c (read_dbx_symtab): If we encounter a "FORTRAN COMMON"
4094 symbol in its raw form, we are processing an unlinked ".o" file.
4095 See if the target environment has assigned it an address, using
4096 target_lookup_symbol (VxWorks does), and enter it into the symtab
4099 * tm-vxworks.h (FRAME_CHAIN, FRAME_CHAIN_VALID): Override usual
4100 68k versions for a simpler version that assumes zero FP at bottom.
4101 Fixes bug of truncated stack reports.
4103 * target.h (target_lookup_symbol): Define this routine's args
4104 and result, finally.
4106 * target.c (nosymbol): Default routine for target_lookup_symbol.
4107 (target_default): Default lookup_symbol and call_function too.
4108 (files_info): Only print has_all_memory warning if a non-dummy
4111 * remote-vx.c (vx_read_register, vx_convert_to_virtual,
4112 vx_convert_from_virtual): If target does not have floating point,
4113 zero register "values", and avoid doing cross-net conversions.
4114 (vx_lookup_symbol): Rename net_lookup_symbol, add to vectors.
4115 (vx_open): Rearrange code that attaches to target and reads
4116 symbols for all loaded modules, to work if some of the modules
4117 are not accessible. Add symbol_stub() and add_symbol_stub()
4118 as callbacks from catch_errors(). Allow connect attempt to be
4119 interrupted painlessly with ^C (FIXME, there are still some bugs
4120 if the interrupt happens during symbol reading.). Print
4121 final message with puts_filtered, since symbol messages are
4126 * main.c (catch_errors): Only print errstring if non-null.
4127 (command_loop): Avoid an ioctl per command to test ISATTY.
4129 * remote-vx.c (net_load): make static; avoid sophomoric msg.
4130 (vx_xfer_memory): Return correct result!
4131 (vx_files_info): Indicate whether target has float or not.
4132 (vx_lookup_symbol): Complain, not error, if target gone.
4133 (vx_open): Print "Connected" msg before disabling immediate-quit.
4134 [FIXME: lookup_symbol and vx_open changes need testing.]
4136 target.c, remote-eb.c, inftarg.c, am29k-opcode.h, target.h,
4137 tm-29k.h, tmm-vxworks68.h, symfile.c, gdb-int.texinfo: Add
4138 contributor lines and update copyrights to 1991.
4140 Changes from an attempted H-PUX host port:
4142 * infptrace.c (PT_ATTACH, PT_DETACH): Handle HP/UX, which
4143 defines PT_ATTACH and PT_DETACH but not PT_KILL.
4144 * remote-eb.c (eb_open): Misplaced endif kills sysv H/PUX.
4145 * remote-vx.c: include <sys/time.h> for HPUX.
4146 * hp300hpux-xdep.c (fetch_core_registers): Rewrite old
4147 "core_file_command" routine to BFD regime. May not work yet.
4149 Attempted port of "gdb-3.4 Van Jacobson xgdb" to modern gdb.
4151 * xgdb.c: Replace X10 version with some VJ version.
4152 (FIXME: Its copyright assignment is not on record.)
4153 * xgdb.c: Update include files to X11R4 (Xaw crud).
4154 (xgdb_display_source, create_text_widget): fix call to
4155 get_filename_and_charpos. Rewack source window stuff for X11R4
4156 (gleaned from include files, and "nm's" of binary libraries, since
4157 I had no doc available).
4158 (append_selection, append_selection_word): Disable with FIXME
4159 since R4 changed interface here.
4160 (create_buttons): Add back the old set of buttons.
4161 (xgdb_create_window): Fix call to XtInitialize (&argc not argc).
4163 * Makefile.dist (xgdb, xgdb-init.c): Update for X11R4 on Suns.
4164 Roll VERSION to 3.94 (not yet final though).
4166 Sat Feb 9 09:46:25 1991 John Gilmore (gnu at cygint.cygnus.com)
4168 * obstack.h (obstack_ptr_grow, obstack_ptr_grow_fast,
4169 obstack_int_grow, obstack_int_grow_fast): Eliminate
4170 cast on left of assignment, which gives MIPS cc fits and is
4173 * sparc-pinsn.c (print_insn): Eliminate 'set' test, subsumed by
4174 F_ALIAS. Use printf, not fprintf, when not passing a file
4176 (compare_opcodes): Check that identical instructions have
4177 identical opcodes, complain otherwise.
4179 * sparc-opcode.h (st %fsr): Fix opcode "lose" mask. This
4180 was reported by Roland McGrath.
4181 (unimp): Only match if exactly zero instruction. (Roland)
4182 (branches and traps): Generate all variations of these
4183 instructions with macros, based on a single call that defines
4184 each condition name and its binary representation.
4185 (set): Turn on alias bit, to avoid test in sparc-pinsn.c.
4187 * valprint.c (val_print_fields): Take, and use, format parameter.
4188 This means that "p/x struct" again prints the elements in the
4189 desired format. Changed callers.
4191 * stack.c (frame_info): Use filtered output, and indicate wrap
4192 points. Remove kludgy formatting designed to avoid line wrap.
4194 * utils.c (wrap_here): If the line is already full (because
4195 we had printed a long indent or long wrapped string), do an
4196 immediate newline-and-indent.
4198 * m68k-pinsn.c (print_insn_arg): Bugfix from
4199 ntmtv!thompson@ames.arc.nasa.gov (Mike Thompson): 'bkpt #0'
4200 instruction is incorrectly disassembled as bkpt #8.
4202 * dbxread.c (end_psymtab): Bugfix from Peter Schauer
4203 <pesrem@regent.e-technik.tu-muenchen.de>: If you want to set a
4204 breakpoint in a *.y file gdb will say Reading in symbols for *.y...
4205 and then will dump core (sometimes). I traced it back to an
4206 uninitialized symfile_name in psymtab_to_symtab.
4207 (const_vol_complaint): Add quotes to message.
4208 (define_symbol): Only believe line number if gcc_compiled.
4209 Avoid allocating symbol if we will not return it.
4211 Add target strata support so that newly established targets go
4212 into their right place in the target stack (e.g. a new exec file
4213 doesn't wipe out the ability to access the running process).
4215 * target.h, core.c, exec.c, inftarg.c, remote-eb.c,
4216 remote-nindy.c, remote-vx.c, remote.c, target.c: Add to_stratum
4217 and initialize it properly in all the targets.
4219 * target.h: Document strata. Change return type of push_target.
4221 * target.c (nomemory): new function for dummy memory access.
4222 (tcomplain): Rename complain, now also used in symfile.c.
4223 (push_target): Push targets within strata. New return value shows
4224 whether new target is on top of stack or not. Always keep dummy
4226 (target_files_info): Ignore dummy target.
4228 * core.c (core_open): Warn user, and skip accessing file, if the
4229 core target is not the topmost target in the stack.
4230 * remote-nindy.c (nindy_create_inferior): Avoid unpush_target, now
4233 * remote-vx.c: Remove vx_prepare_to_store from vxworks memory
4234 target_ops, it doesn't belong there since we have no regs there.
4235 Change name of target from machine => memory to clarify.
4237 Thu Feb 7 16:32:09 1991 John Gilmore (gnu at spiff.cygnus.com)
4239 * Freeze version 3.93 for release.
4241 * Makefile.dist: Handle vx-share and nindy-share subdirs
4242 properly when building gdb.tar.Z.
4244 * symtab.c: lint; add no_symtab_msg to consolidate the messages
4245 printed in various places, so I could change just one copy.
4247 * dbxread.c, coffread.c: Change references to bfd->iostream
4248 to cast to FILE *, now that BFD avoids needing types defined
4249 in other header files.
4251 Tue Feb 5 21:39:35 1991 John Gilmore (gnu at cygint.cygnus.com)
4253 * command.c, dbxread.c, expprint.c, infcmd.c, infptrace.c,
4254 infrun.c, printcmd.c, remote-nindy.c, source.c, sparc-tdep.c,
4255 sparc-xdep.c, symfile.h, symmisc.c, utils.c, valprint.c: Lint
4256 (actually gcc -Wall).
4258 * dbxread.c: Remove first_global_sym, last_global_sym, since
4259 they are never referenced.
4261 * defs.h (baud_rate): Declare.
4262 main.c: Define it, and add the -b option to set it.
4264 * gdb-int.texinfo: Add text on how to define a new host or target
4265 architecture, prompted by Per Bothner's questions about MIPS
4268 * gdb.texinfo: Document "complaints". Change doc of -q since
4269 gdb no longer prints the copyright and blurb if you specify a file
4270 name to be debugged (just like Emacs). Add doc for Nindy-specific
4271 command line flags for specifying target serial port and such.
4272 Update copyright to 1991.
4274 * gdbcore.h: Remove a large mass of now-useless crud, since BFD
4275 has taken over for us the job of ripping up executable files. The
4276 crud caused Per Bothner's port to not compile.
4278 * infrun.c (normal_stop): Avoid printing "Program exited
4279 normally" if we are in batch mode. This allows a GDB which
4280 executes a program on a target system, to behave like a Unix
4281 command (input from stdin, output to stdout, no extraneous
4284 * main.c (main): Allow additional machine-dependent command line
4285 options to be specified with the ADDITIONAL_OPTIONS,
4286 ADDITIONAL_OPTION_CASES, ADDITIONAL_OPTION_HELP, and
4287 ADDITIONAL_OPTION_HANDLER macros. Also allow machine-dependent
4288 processing to occur just before the main loop with
4289 BEFORE_MAIN_LOOP_HOOK.
4290 (main): If a "core file" argument is specified, and it is not a
4291 core file, try it as a process ID to attach.
4292 (symbol_completion_function): Attempt to cope with
4293 "show screen-" TAB, not very successfully. This needs more work,
4295 (batch_file): New function, returns whether we are reading
4296 commands from an interactive tty on stdin, or from somewhere else.
4297 Called by normal_stop since it doesn't get from_tty passed down
4298 to it like many commands do.
4300 * remote-nindy.c: Handle command line options for nindy
4302 (nindy_before_main_loop): Prompt user for tty name if they
4303 don't specify it before getting to the interactive command loop.
4305 * tm-i960.c: Add ADDITIONAL_OPTIONS, etc, to handle -O, -brk,
4306 and -r command line options. Also add hook before main loop
4307 to make it easy to specify a tty.
4309 * TODO: More things to do, one done.
4311 Mon Feb 4 23:57:39 1991 John Gilmore and Mike Tiemann (at cygint.cygnus.com)
4313 * dbxread.c: Make complaint() calls pass pointer, not struct.
4314 Add complaints about badly formatted C++ type information
4315 (const/volatile indicator, and parse errors resulting in
4316 error_type). Fix C++ virtual member fn comment.
4317 (read_struct_type): Avoid bumping pointer if we got a parse
4318 error; this prevents our walking beyond the end of a string.
4319 Terminate loop on null char as well as semicolon.
4320 (process_one_symbol): Fix the LBRAC fix so that it uses the
4321 last previous SLINE, FUN, or SO record's PC address. C++ debug
4322 symbols did not have SLINE records in a useful order compared
4323 to the LBRAC records.
4324 (define_symbol): Handle "catch" records.
4326 * symtab.c (check_stub_type): Added new complain
4327 `stub_noname_complain' and added a consistency check to
4328 keep the debugger from crashing when finishing from an
4329 exception frame. A real fix will be needed later.
4331 Sat Feb 2 10:43:05 1991 John Gilmore (gnu at cygint.cygnus.com)
4333 * infcmd.c (attach_command): Make global.
4335 * Makefile.dist (REMOTE_OBS): Make these compile by default,
4336 but make them easy to comment out. Perhaps later they should
4337 be enabled by what CPU you configure for? FIXME.
4338 (VERSION): Roll to 3.93.
4339 (pinsn.o): Remove rule for obsolete file.
4340 (dbxread.o,coffread.o,mipsread.o): Use ${srcdir} explicitly.
4342 Run down a problem that manifested by printing the wrong function
4343 name in stack traces of read_ofile_symtab. Turned out that the
4344 problem was the SunOS 4.1.1 (and previous) C compiler outputs
4345 the LBRAC symbol with an address in the *data* segment, which
4346 blew our binary search through the blocks.
4348 * dbxread.c: Use the complain() facility consistently to bitch
4349 about problems in the symbol file we are reading.
4350 (finish_block): Add code to check the nesting of the blocks;
4351 complain and Procrust them to fit if wrong.
4352 (make_blockvector): Check the order of the blocks, complain
4353 [but don't cope] if wrong.
4354 (process_one_symbol): ifndef SUN_FIXED_LBRAC_BUG, check LBRAC
4355 symbols to be sure their PC value is greater than the last SLINE
4356 (line number) symbol we've seen, complaining and adopting the
4357 SLINE PC value if wrong.
4359 * symfile.h (struct complaint, complaint_root, complain,
4360 clear_complaints): Add.
4361 * symfile.c (complain, complaint_root, clear_complaints): Add
4362 facility to deal with non-fatal complaints and to regularize their
4364 (symbol_file_add): Clear complaint counters to allow new complaints.
4365 (initialize_symfile): Add 'set complaints' and 'show complaints'.
4367 * dbxread.c (dbx_symfile_read): Remember the address and size
4368 of the string table for the main symbol file, so we won't read it
4370 (dbx_psymtab_to_symtab): Fix the check for main symbol file,
4371 to avoid reading the string table yet again. Lint.
4372 (throughout): Improve filtered output, including word wrap.
4373 (read_range_type): Improve Bothner's fix to handle other types too.
4375 * utils.c: Improve line wrap implementation. Handle unlimited
4376 width by making chars_per_line unsigned.
4377 (puts_filtered): New, easy, function.
4379 * defs.h (puts_filtered): add.
4381 * mipsread.c (compare_symbols, sort_symtab): Remove these fns,
4382 call the identical sort_symtab_syms() in symfile.c instead.
4384 * expread.y: Suggest the `file' command rather than `symbol-file'.
4386 * command.h (enum var_types): Add zinteger for seroable
4388 * command.c (do_setshow_command): Handle var_zinteger. Restructure
4389 nested if's into a switch.
4391 * breakpoint.c (bpstat_print): If bpstat "print" flag is not set,
4392 we did not stop because of a breakpoint (it must have been for
4393 some other reason, like a "stepi"), so don't print anything.
4395 * symtab.c: Include <sys/types.h> all the time. Now that BFD
4396 doesn't include <sys/types.h>, old SunOS's require it for
4399 Sat Feb 2 10:39:15 1991 Per Bothner (bothner@cs.wisc.edu)
4401 A test port of gdb-3.92.6 to the Sony NEWS.
4404 Don't normally link in remote- or vx stuff.
4405 Some of it doesn't compile, and it wastes space for 99% of the users.
4406 Remove reference to no-longer-used HAVE_VPRINTF.
4407 Fixed BFD_DEP typo to BFD_DIR.
4409 Fix cast in arg to bfd_h_getlong.
4410 Make char *prefix be const.
4411 Fix how certain range types are mapped into builtin unsigned int types.
4413 Remove 2 #includes. They cause errors (on Sony, at least),
4414 and aren't needed (they wern't in earlier versions).
4416 print_address_symbolic should never demangle labels
4417 (since it prints *assembler-level* labels).
4419 [This was superseded by the change to printcmd below.]
4422 Add some "volatile" return types to avoid warnings.
4423 If MISSING_VPRINTF add vprintf function and not just macro
4424 (since vprintf is used in printcmd.c).
4426 Unless __GNUC__, use obstack_grow instead of obstack_ptr_grow.
4427 (The latter isn't grokked by some PCC-based compilers.)
4429 [This change is in abeyance, we prefer to fix obstack_ptr_grow.]
4431 Make chunk size of dont_print_obstack 32*4 instead of default 4096.
4432 * nindy-share/coffstrip.c
4433 Added some forward declarations (otherwise, gcc complains
4434 about implicit extern redefined as static).
4436 Sun Jan 20 02:38:19 1991 John Gilmore (gnu at cygint.cygnus.com)
4438 Changes inspired by Per Bothner:
4439 * printcmd.c (print_address_symbolic): Take additional parameter
4440 specifying whether to demangle.
4441 (print_address): Pass in asm_demangle to control demangling.
4442 (print_address_demangle): New fn, takes explicit arg to control
4444 * utils.c: Add new vars demangle and asm_demangle, and let them
4446 (fputs_demangled): If !demangle, just print the argument.
4447 (fprint_symbol): If !demangle, just print raw symbol.
4448 * valprint.c (val_print): Call print_address_demangle rather than
4449 print_address, to cause demangling to depend on the global
4450 rather than assembler-level demangling setting.
4451 * WHATS.NEW, gdb.texinfo: Document.
4453 * main.c (show_command): Show all settings if no arg.
4454 (initialize_main): Make "info set" the same as naked "show".
4455 * command.c (cmd_show_list): Handle prefix commands in the
4456 list, and print the name of the setting as well as its English
4457 description and value.
4459 Allow gdb functions to specify where a line should wrap if it
4460 exceeds the size of a terminal line. Use it to make the output
4462 * utils.c (set_screen_width_command): New fn, mallocs a buffer
4463 of the right size when screen width changes.
4464 (set_screensize_command, screensize_info): Remove #if 0'd fns.
4465 (wrap_here): New fn, indicates a point in the output where we
4466 should wrap the line rather than just letting it overflow at a
4468 (fputs_filtered): Implement wrapping.
4469 (n_spaces): New fn, returns a pointer to N spaces.
4470 (print_spaces_filtered): Use n_spaces.
4471 * defs.h (n_spaces): Declare.
4472 * stack.c (print_frame_info): Wrap with 4-space indent after
4473 fn name and before filename and line number.
4474 * printcmd.c (print_frame_args): Wrap with 4-space indent
4475 before each argument name is printed.
4476 * valprint.c (value_print): Wrap with no indentation before
4478 (val_print_fields): Wrap with indentation relative to nesting
4479 level before each field name.
4480 (val_print): Wrap with nesting indentation before array elements.
4481 * command.c (do_setshow_command): Avoid extra newlines,
4482 wrap with 4-space indent around values printed, end with period.
4483 * WHATS.NEW, gdb.texinfo, gdb-int.texinfo: Document.
4485 * breakpoint.c (breakpoint_1): Implement addressprint for
4486 "info breakpoints" display. Change file name and line number
4487 format to " at file:nnn" rather than " (file line nnn)".
4488 * gdb.texinfo: Document.
4491 Fri Jan 18 07:21:25 1991 John Gilmore (gnu at cygint.cygnus.com)
4493 Frozen for gdb-3.92.6 release.
4495 README, WHATS.NEW: Update for 3.92.6 release.
4497 tconfig/{altos, i386v, i386v32, m88k, umax}: Eliminate
4498 coffread.o from configs since it is now built by default.
4499 tconfig/{3b1, altosgas, arm, convex, hp300bsd, hp300hpux,
4500 i386v-g, i386v32-g, isi, merlin, news, news1000, np1, pn,
4501 pyramid, symmetry, vax, vxworks68}: Eliminate dbxread.o
4502 from configs since it is now built by default.
4504 Makefile.dist: Update for release 3.92.6. Handle files that
4505 have been moved to ../include, ../getopt, or ../bfd. Add
4506 saber.suppress and tests directory. Add config.status to
4507 the release (it will say "none").
4509 coredep.c: Minor formatting fixes.
4511 These changes were made in early December but only checked in now:
4512 * nindy-share/Onindy.c, nindy-share/coffstrip.c,
4513 nindy-share/nindy.c: lint
4514 * nindy-share/nindy.c (ninStopWhy): Don't byteswap the
4515 register values coming back from the target; we store values
4516 in target byte order everywhere.
4518 Wed Jan 16 19:01:37 1991 John Gilmore (gnu at cygint.cygnus.com)
4520 * am29k-opcode.h, am29k-pinsn.c: Add 29050 opcodes.
4522 * valprint.c (cplus_val_print, val_print_fields): New functions,
4523 which print C++ objects. They conspire to avoid printing a
4524 virtual base class more than once, following all the twists and
4525 turns of C++ virtual base rules.
4526 (val_print): Call the above rather than do it by hand.
4528 * symfile.c (symbol_file_add): Only reset symfile_mtime for main
4529 symbol file, not for added files like shared libs. This really
4530 needs to be generalized to a timestamp per file.
4532 * core.c (cleanup_core): Avoid coredump if no core file.
4534 * config.gdb: Accept -host or -target in place of +host or
4537 * coffread.c (find_linenos): Avoid desupported BFD interface
4538 to line numbers. We still read them manually rather than using
4539 BFD's "generic" features.
4541 * gdbrc.tex, threecol.tex: Add GDB reference card and its
4543 Makefile.dist: Add refcard to OTHERS list for creating tar files.
4545 * Makefile.dist: Eliminate use of $< in explicit targets.
4547 * readline/Makefile: Use $< rather than $*.c, which does not
4548 include the VPATH in GNU Make.
4550 * tconfig/i960-bout, tconfig/i960-coff: These are identical
4551 copies of tconfig/i960, added for global configuration
4552 compatability. All i960 versions can read both coff and b.out.
4554 * tm-88k.h: Fix multiline macro that lacked \'s. Remove
4555 COFF_FORMAT and COFF_CHECK_X_ZEROES since these are now handled
4558 * TODO: Think of more things to do.
4560 Wed Jan 2 19:09:29 1991 John Gilmore (gnu at spiff.cygnus.com)
4562 tconfig/{am29k,i960,sun2*,sun3*,sun4*}: Eliminate config
4563 of sdb versus dbx debug symbols. Add kludge for 68881 80-bit to
4564 64-bit float conversion.
4566 tconfig/sun4, tconfig/sun3, xconfig/sun4, xconfig/sun3: Make
4567 equivalent to sun?os4 so global config works.
4569 Wed Jan 2 18:20:51 1991 John Gilmore (gnu at spiff.cygnus.com)
4571 Fix from Eberhard Mattes <mattes@azu.informatik.uni-stuttgart.de>
4573 * main.c: Only declare linesize once; declare pagesize not at
4574 all, since it is never used.
4575 (main): Clear newly allocated line before it is used.
4577 Fri Dec 28 00:13:42 1990 John Gilmore (gnu at cygint)
4579 Further stabilization for the Intel 960.
4581 * Makefile.dist: Parameterize the location of the "include"
4582 and "bfd" directories, as well as "getopt". Add symfile.c.
4583 Link in both dbxread and coffread. Fix up "make depend" to
4584 rewack the locations of include, bfd, and getopt in its output.
4586 * README: Document moving include files, improve some of
4589 * coffread.c: Move common code out to symfile.c. Change
4590 symbol_file_command style interface to use new *_symfile_init
4591 and *_symfile_read interface under BFD. Use BFD internal
4592 info to locate line table, symbols, etc.
4594 * core.c (core_fetch_registers): Rename to get_core_registers
4595 to avoid confusion with fetch_core_registers.
4596 (register_addr): Move to coredep.c, which is already machine
4597 dependent. This leaves core.c pretty clean of dependencies.
4599 * coredep.c (register_addr): Accept this routine from core.c.
4601 * dbxread.c: Move common code (with coffread.c, etc) into new
4602 symfile.c. Each psymtab now contains a pointer to the
4603 format-dependent function that knows how to read it in. Make
4605 (dbx_psymtab_to_symtab): Renamed from psymtab_to_symtab_2.
4606 (process_one_symbol): Add code to complain about a "compiler bug
4607 we muzzle here", if we actually see it.
4609 * eval.c (evaluate_subexp): Insert missing "break" statements
4610 in code that determines whether a variable is an lvalue in
4611 memory, register, or whatever. I detected this via a compiler
4612 bug in which it *almost* mashed out the whole switch statement.
4614 * gdb-int.texinfo: Add minor sections on configuring gdb for
4615 release, and about the README file.
4617 * infcmd.c (registers_info): Fix formatting somewhat. Still
4618 not as pretty as before, but it handles byte swapping.
4620 * remote-nindy.c: If data cache routines are interrupted while
4621 waiting for the remote end, be sure that any uninitialized cache
4622 blocks are on the free list, not on the valid list!
4624 * symfile.h: Flesh out this header file with all the various
4625 routines and variables that have been merged in from dbxread.c
4626 coffread.c, and symtab.c to symfile.c.
4628 * symfile.c: New file, containing code common to dbxread.c,
4629 coffread.c, and some code from symtab.c. All generic code for
4630 reading symbol files should be in here now.
4631 (unrecord_misc_function): Remove unused function.
4633 * symtab.h: Remove file-reading things to symfile.h.
4635 * symtab.c: Remove file-reading things to symfile.c.
4637 * tm-i960.h: Fix FRAME_CHAIN types; define PRINT_RANDOM_SIGNAL
4638 to decode i960 fault types.
4640 * target.h, remote.c, remote-eb.c, remote-vx.c, remote-nindy.c,
4641 target.c: Change type of the "resume" function from int to void,
4642 since its result was never used.
4644 Sat Dec 22 02:51:40 1990 John Gilmore (gnu at cygint)
4646 * main.c: Replace "stupid" with "caution"; you now "set caution
4649 * printcmd.c (print_scalar_formatted): Fix typo in 'g' format
4651 * infcmd.c (do_registers_info): Call val_print to deal with the
4652 byte order of the registers being printed. FIXME, this makes
4653 the formatting of the output uglier.
4655 * infcmd.c (wait_for_inferior): If PRINT_RANDOM_SIGNAL is
4656 defined, call it for signals the debugger doesn't itself use.
4657 The i960 uses this for more detailed fault information.
4659 * remote.c (remote_open): If arg is null, print help rather than
4662 * sparc-xdep.c (register_valid): Avoid declaring size, since
4663 various modules will think of various sizes depending on the
4664 architecture of their tm-file. FIXME, we need protection against
4665 actually entering one of those modules, which would clobber
4666 storage if not for the target architecture compiled into gdb.
4668 * stack.c (up_command, down_command): Always print the frame
4670 (up_silently_command, down_silently_command): New commands
4673 * i960-pinsn.c (reg), i960-tdep.c: Lint.
4675 * i960-tdep.c (i960_frame_chain_valid): Lookup_symbol now takes
4676 more parameters than it used to.
4678 * findvar.c (registers): Increase slop to 256 bytes, which should
4679 protect us against even most RISC machines with large register
4681 (locate_var_value): Move declaration inside related ifdef.
4683 * remote-nindy.c (): Use TIOCSETN rather than TIOCSETP
4684 throughout, to avoid throwing away buffered input from the board.
4685 (nindy_wait): Supply_register takes addr_of_value, not value.
4686 (i960_print_fault): Renamed from i80960_fault.
4687 (nindy_fetch_registers): Avoid have_regs stuff, just get them.
4688 (nindy_store_registers): Avoid regs_changed stuff, just stuff
4690 (nindy_create_inferior): Don't bother to write PC_REGNUM since
4691 we can set the PC in the call to proceed(). Unpush nindy_ops
4692 before pushing it on top, to avoid message to user. Eliminate
4693 commentary from Unix machines that just misleads here.
4694 (reset_command): Fix error message to suggest target command.
4696 Wed Dec 19 11:03:56 1990 John Gilmore (gnu at cygint)
4698 Release 3.92.5 as frozen.
4700 Stabilize the merged release...with help from lint, Saber C,
4703 Everywhere: Add include files needed to declare return types
4704 of functions called.
4706 * gdb.texinfo: Roland Pesch is documenting gdb, glory be!
4708 * breakpoint.h: Add undeclared breakpoint functions, and some
4709 functions for display handling since I couldn't think of a better
4712 * breakpoint.c (insert_breakpoints): Make code for disabling
4713 shared library bkpts more likely to work. It's used when we
4714 rerun a program and stop before the shared library has been
4716 (breakpoint_cond_eval, bpstat_stop_status): Pass arg as int,
4717 cast from pointer, so it squeezes through catch_errors.
4718 (bpstat_stop_status): Fix logic broken some time ago. We now
4719 always create a bpstat if the stop address matches a breakpoint,
4720 even if we don't stop there -- just like the old code used to do
4721 before I got my fingers into it (sigh).
4722 (breakpoint_1): Print "ignore count" after "stop only if"
4723 condition, since that's how it actually works.
4724 (mention): Handle watchpoints as well as breakpoints.
4725 (watch_command): use set_raw_breakpoint and mention to do most
4726 of the work (and initialize all the fields!). Only pass one
4727 arg to parse_c_expression, since that's all it takes.
4729 * command.c (not_just_help_class_command): Rename arg to args
4730 since we ignore "unused argument" warnings on vars named "args".
4731 inflow.c (child_terminal_info): ditto.
4732 infptrace.c (kill_inferior): ditto
4733 main.c (catch_errors, version_info, quit_command, pwd_command,
4734 source_command, dump_me_command, editing_info,
4735 set_history_size_command, set_history, show_history,
4737 stack.c (locals_info): ditto
4738 target.c (target_files_info): ditto
4739 valprint.c (set_input_radix, set_output_radix): ditto
4741 * core.c: Remove old variables for handling core and exec file
4742 sections (data_start, data_end, stack_start, stack_end,
4743 reg_stack_start, reg_stack_end, reg_stack_offset, text_start,
4744 text_end, exec_data_start, exec_data_end, text_offset,
4745 exec_data_offset, data_offset, stack_offset). They're
4746 superseded the more general build_section_table and
4748 (get_exec_file): Mention the `file' command.
4749 (read_memory_check): Rename to memory_error, and only call it
4750 in the case of an actual error.
4751 (read_memory, write_memory): call memory_error.
4752 (core_fetch_registers): Register section name is ".reg".
4754 coredep.c: Remove a bunch of crud now that all this file does
4755 is pull the registers out of a core file.
4756 (fetch_core_registers): Rewrite to actually work, I hope.
4758 dbxread.c: Use a.out.gnu.h, not system a.out, now.
4759 Replace index() with strchr(). Remove all the pre-BFD macro
4760 definitions for accessing the symbol file.
4761 (struct dbx_symfile_info): Encapsulate the information that
4762 dbx_symfile_init needs to pass to dbx_symfile_read in this
4765 (dbx_new_init, dbx_symfile_init, dbx_symfile_read,
4766 dbx_symfile_discard): Rearrange symbol file reading to divide
4767 the format-specific part from the format-independent part,
4768 leaving the format-independent part such as file name expansion
4769 and opening in symtab.c. This replaces
4770 partial_symbol_file_open and partial_symbol_file_read.
4771 Symbol_file_read, add_file, add_file_target_command,
4772 add_file_addr_command move to symtab.c. Pass an explicit
4773 "mainline" flag for when reading the main symbol table, rather
4774 than relying on the offset address to be zero or nonzero.
4776 (dbx_symfile_read): Don't allow void *'s to be printed as
4778 (SWAP_SYMBOL): Use bfd routines to byte-swap the symbols.
4779 (ADD_PSYMBOL_TO_LIST): Make the "function call rather than
4780 macro" debug version really work.
4781 (read_dbx_symtab): Remove unref'd parameter inclink.
4782 Avoid swapping N_SLINE symbols, for speed.
4783 Merge N_TEXT!N_EXT case with the other external symbol
4784 definitions' case. Add comments.
4785 (start_psymtab): Allocate the symfile name in the psymtab on
4786 the psymbol_obstack, rather than using the caller's storage.
4787 (end_psymtab): Only allocate a dependencies list if there are
4789 (psymtab_to_symtab_2): Use BFD when reopening file to read
4790 its symbols for real.
4791 (read_struct_type): Add FIXME comments where it needs work
4793 (read_huge_number): Add FIXME about overflows.
4794 (read_range_type): Add FIXME about comparing a long to 1<<32.
4796 * coffread.c: Minor changes to move things closer to the new
4797 regime with symtab.c and dbxread.c Major work is still needed
4800 * exec.c (exec_file_command): Remove old variables (see core.c
4802 (xfer_memory): If memory transfer is right at the end of a
4803 section, don't lose.
4805 * findvar.c (get_saved_register): If value is in a real
4806 register, LVAL is lval_register, not lval_memory.
4808 frame.h: Declare print_sel_frame and record_selected_frame.
4810 gdb-int.texinfo: New file, for GDB internals documentation.
4811 Very simple, unformatted doc of cleanups is there for now.
4813 gdbcore.h: Remove obsolete variables that described a.out
4814 section addresses and offsets. (See core.c above.)
4815 Declare fetch_core_registers and registers_fetched.
4817 getopt.c: Declare char *alloca(); even on SPARC.
4819 infcmd.c (run_command): Call target_kill rather than
4821 (step_command, next_command, stepi_command, nexti_command):
4822 Declare from_tty parameter even though we don't use it.
4823 (run_stack_dummy): argument BUFFER is a char array, not
4824 a pointer to REGISTER_TYPE.
4825 (finish_command): using_struct_return needed a value *,
4826 not a struct symbol *.
4828 * infptrace.c (child_xfer_memory): To avoid dependency on
4829 where sections are in memory, try PT_WRITE_D and if that fails,
4830 try PT_WRITE_I. Most Unixes don't care which you use.
4832 * infrun.c (step_resume_break_shadow): Change to array to
4833 match other breakpoint shadow storage.
4834 (clear_proceed_status): Pass address of bpstat to
4835 bpstat_clear, not the bpstat itself.
4836 (child_create_inferior): FIXME comment about if the child
4838 (start_inferior): Remove old function.
4839 (child_open): Use target_kill rather than kill_inferior.
4840 (wait_for_inferior): Ditto.
4841 (insert_step_breakpoint, remote_step_breakpoint): Use
4842 new step_resume_break_shadow.
4844 * inftarg.c (child_wait): If all child processes die,
4845 pretend that the one being waited for exited with signal 42.
4847 * main.c (command_line_input): When scanning for comments,
4848 don't coredump on unclosed quotes.
4849 (quit_command): Use target_kill rther than kill_inferior.
4850 (_initialize_main): Rename class_user from "user" to
4853 * printcmd.c (print_command_1): Initialize "fmt" if no format
4854 is specified by the user.
4855 (print_frame_args): Only add to args_printed if we are
4856 actually fetching args from the stack (avoiding undefined
4858 (_initialize_printcmd): Remove bogus \{ from string.
4860 * remote-eb.c (eb_open): Avoid coredump on no argument.
4862 * remote-nindy.c: Bring out of Intel environment into new
4863 target environment. Remove all conditional compilation on
4864 I80960. Massive hacking throughout.
4865 (nindy_xfer_inferior_memory): New routine stolen from
4867 (nindy_create_inferior): New routine pieced together, probably
4868 not quite working yet.
4869 (nindy_ops): New target_ops struct for nindy.
4871 * remote-vx.c: Use write_memory rather than target_write_memory
4872 to get error checking.
4873 (vx_add_file_command, vx_open): Use symbol_file_add rather than
4875 (vx_create_inferior): Use target_terminal_ours...
4877 * signame.c (_initialize_signame): Always initialize, since
4878 we need the table for things other than psignal.
4880 * solib.c (solib_add): Use symbol_file_add, not add_file.
4881 (solib_address): Return boolean result rather than struct
4882 pointer which nobody else knows the type of.
4884 * sparc-tdep.c, valops.c: Use write_memory rather than
4885 target_write_memory, to get error checking.
4887 * stack.c (locals_info, catch_info, args_info,
4888 get_selected_block, frame_command, up_command): Use
4889 target_has_stack, rather than have_inferior_p or
4892 * sun3-xdep.c (fetch_core_registers): Rewrite for new BFD regime.
4894 * symfile.h: New file, defining the interface between the
4895 generic and object-file-specific symbol reading code.
4897 * symtab.c: Move generic symbol-reading interface to symtab.c,
4898 from dbxread.c, coffread.c, mipsread.c, etc. Add symtab_fns
4899 table to map BFD targets to symbol-reading modules in GDB.
4900 Change index to strchr.
4901 (lookup_struct_elt_type): Use error() rather than hand-made
4902 simulations thereof.
4903 (lookup_partial_symbol): Speedup slightly when length == 0.
4904 (symbol_file_add): New function.
4905 (symbol_file_command): Call it.
4906 (symfile_open, symfile_init): New function.
4907 (add_file_target_command, add_file_addr_command): moved from
4910 * target.c (target_command): use target_kill.
4912 * target.h (target_files_info): Don't declare, never called
4915 * tm-sun2.h, tm-sun3.h (STACK_END_ADDR): Use system include
4916 files to determine stack end address.
4918 * valarith.c (value_x_binop, value_x_unop): Change error message
4919 to be more useful. Pass proper argument to value_struct_elt.
4921 * valops.c (value_assign): FIXME comment that long long
4922 bitfields will break here.
4924 * Makefile.dist: Add symfile.h, remote-nindy.c, remote-eb.c.
4925 Update `make saber_gdb' to work better.
4927 * TODO: A woman's work is never done.
4929 * cplus-dem.c, environ.c, inferior.h, infrun.c, inftarg.c,
4930 main.c, obstack.c, printcmd.c, remote-eb.c, remote-nindy.c,
4931 remote-vx.c, remote.c, solib.c, source.c, sparc-pinsn.c,
4932 sparc-tdep.c, sparc-xdep.c, symmisc.c, symtab.c, symtab.h
4933 target.c, terminal.h, tm-sparc.h, tm-sunos.h, utils.c,
4934 valops.c, valprint.c, exec.c: Lint.
4937 Wed Dec 12 23:44:15 1990 John Gilmore (gnu at cygnus.com)
4939 Continuing Intel 960 port merge of GDB.
4941 * Makefile.dist: Merge i960 "nindy-share" files. Rename
4942 malloc.h to gmalloc.h to avoid name conflicts in /usr/include.
4943 Don't ship gdb.dvi in tar file. Link gdb with init.o, not init.c.
4944 Wack over "make depend" so it handles files in subdirectories
4945 vx-share, nindy-share, bfd, and in the current directory.
4947 * blockframe.c (get_prev_frame_info): Remove fatal error
4948 if stack not defined.
4950 * core.c (core_open, core_detach): New functions that handle
4951 the old "core-file" command as "target core" and "detach" instead.
4952 (core_file_command): Call them.
4953 (core_xfer_memory): Use common routine xfer_memory.
4955 * dbxread.c: Include a.out.gnu.h, not system a.out.h.
4956 dbxread now uses bfd for everything but symbol reading itself.
4957 BFD internals are used to drag out the relevant file offsets.
4958 (partial_symbol_file_open): Change args all around for BFD.
4960 * symtab.c: Rename "value" to "val" everywhere, so we can
4962 (symbol_file_command): New command, moved from dbxread.c
4963 and coffread.c. It uses BFD to read the file, then vectors
4964 based on its type, to dbx or coff symbol readers.
4965 * symtab.h: Extern a few vars for symbol_file_command.
4967 * target.h: Breakpoint takes a char * save area, not a char **.
4969 * valprint.c (val_print): When unpacking bitfields, offset
4970 the address in gdb of the value, if it is declared with a shorter
4971 type. Remove the last "runtime kludge test" of host byte order.
4973 * utils.c: Remove old my_bfd_read routine.
4975 * stack.c (frame_info): Use target_has_stack. Print program counter
4976 register's actual name rather than "pc", since it's called the
4977 "ip" (instruction pointer) on the i960 (sigh).
4979 * target.c (target_command): Add command for selecting a target
4980 type and calling its open routine. This is used for initiating
4981 communication with a particular target, in a generic way.
4983 * tm-i960.h: Update for modern gdb. Remove semicolons from
4984 various macros. Handle reading struct return convention, and
4985 error-out attempts to return structs with the "return" command.
4986 Be sure gdb doesn't think we know how to call functions in the
4989 * i960-tdep.c: Rename FRAME_CHAIN_VALID and FRAME_FIND_SAVED_REGS
4990 to i960_xxx in lower case.
4991 (arg_address): Circumvent errors due to LOC_ARG_BLOCK
4992 not being defined yet.
4994 * remote.c (remote_open): Call start_remote to initialize
4995 wait_for_inferior during open.
4996 (remote_xfer_inferior_memory): Return length written rather
4999 * remote-vx.c (target_command -> vx_open): Use new generic
5001 * remote-eb.c, inftarg.c, exec.c: ditto.
5003 * infrun.c: Fix comments.
5004 (attach_program -> child_open): Use new generic target command.
5005 (wait_for_inferior): Clear saved register values before target_wait,
5006 so target_wait can set some of them if convenient.
5008 * infptrace.c (fetch_inferior_registers, store_inferior_registers):
5009 Return success indicator, not void.
5010 (child_xfer_memory): Avoid fetching initial word if we'll
5011 overwrite it anyway.
5013 * infcmd.c (attach_command): Use new generic target open routine.
5014 (_initialize_infcmd): Update doc on attach and detach commands.
5015 (do_registers_info): Merge in a byte-order problem as a FIXME
5018 * findvar.c (find_saved_register): Avoid problem in current frame.
5019 (read_relative_register): Ditto.
5020 (write_register): Convert byte order on the way out.
5022 * exec.c (file_command): Add.
5023 (add_to_section_table, exec_command): Use new bfd_map_over_sections.
5024 (xfer_memory): Common function between core_xfer_memory and
5026 (exec_xfer_memory): Use it.
5028 * pn-opcode.h: Document that a "PN" is a Gould PowerNode.
5030 * breakpoint.c, breakpoint.h, symtab.h, value.h, frame.h, utils.c,
5031 valops.c, stack.c, target.c, sparc-xdep.c, source.c, printcmd.c,
5032 infcmd.c, i960-pinsn.c, eval.c, defs.h: lint and gcc -Wall.
5034 Sun Dec 2 16:45:06 1990 John Gilmore (gnu at cygnus.com)
5036 Merge Intel 960 port of gdb, continuing...
5038 * dbxread.c (partial_symbol_file_open, partial_symbol_file_read,
5039 symbol_file_command): Pass from_tty arg to hush 'em up.
5041 * coffread.c (symbol_file_command): Avoid output if from_tty != 1.
5042 Add magic numbers for 960 COFF format.
5044 Fri Nov 30 09:18:20 1990 John Gilmore (gnu at cygnus.com)
5046 Merge Intel 960 port of gdb, from Intel "1.2" release.
5048 CHANGE_LOG entries from their port, which was based on
5051 Thu Sep 6 11:02:22 PDT 1990
5052 Remove temp file if download is interrupted.
5054 Wed Aug 1 09:08:33 PDT 1990
5055 Now uses binary protocol to talk to NINDY.
5056 Old hex protocol (NINDY 2.13 and older) supported with -O switch.
5057 Times out after 5 seconds when trying to talk to NINDY.
5059 Tue May 29 12:54:49 PDT 1990
5060 Added variable baud rate (-b switch).
5061 Source code reorganization.
5063 Thu Apr 26 11:09:55 PDT 1990
5064 More cleanup of batch mode; specifically, execute "-s", "-e", and
5065 "-se" switches as soon as they are encountered on the invocation line.
5067 Fri Apr 20 13:47:15 PDT 1990
5070 Thu Apr 19 09:54:28 PDT 1990
5071 Add 'reset' command.
5073 Wed Apr 18 09:48:07 PDT 1990
5074 After opening remote tty, wait for 1 second to go by without input
5075 from it before trying to talk to NINDY (fixes problems with the
5076 Heurikon HK80/V960E).
5078 Mon Apr 4 16:33:05 PDT 1990
5079 Some output was not being suppressed in 'batch' mode.
5081 Thu Mar 22 15:31:11 PST 1990
5082 Ask user if old symbol table should be deleted when new file is
5085 Allow user to run a program downloaded before gdb960 was brought up.
5087 Correct "exec-file" help message for i80960 context.
5089 Correct bug in calculating user space address: could occasionally
5090 corrupt user program.
5092 Make sure to zero low-order bits in rip's because of bug in 960CA
5093 A-step part: could cause operation faults when "next"ing across
5096 Correct bug that made it impossible to get source line numbers for
5097 code loaded at addresses higher than 0x7fffffff.
5099 Wed Jan 10 12:43:22 PST 1990
5100 Open remote tty for exclusive use.
5102 Fri Jan 5 12:14:42 PST 1990
5103 Correct disassembly (CA manual was right after all):
5104 opcode for sysctl is 0x659
5106 Mon Oct 23 12:03:04 PDT 1989
5107 Use G960BASE and G960BIN environment variables to find 'sx' utility.
5109 Mon Oct 16 14:15:09 PDT 1989
5110 "sfr0"-"sfr31" should have been named "sf0"-"sf31"
5112 Mon Oct 2 15:56:31 PDT 1989
5114 Added 960CA disassembly support.
5116 To simplify maintenance:
5117 - eliminated use of symblic links on pinsn.c: use i960-pinsn.c
5119 - eliminated opcode.h: incorporates tables into i960-pinsn.c
5120 - moved 960-specific routines from i960-pinsn.c to i960-md.c
5121 - made disassembly interface identical to that in gdmp960.
5125 Wed Nov 28 21:32:48 1990 John Gilmore (gnu at cygint)
5127 * target.h: Allow targets to stack. Add target_has_memory,
5128 _registers, etc. Restructure memory access and "info files"
5129 to walk the target stack.
5130 * exec.c, core.c, inftarg.c, remote.c, remote-vx.c, remote-eb.c,
5131 target.c: Change tables to match target.h.
5132 * inflow.c (child_mourn_inferior): pop child_ops.
5133 (generic_mourn_inferior): Use new has_stack flag.
5134 * infptrace.c (child_xfer_memory): New memory regime.
5135 * inftarg.c (child_files_info): New "info files" regime.
5136 * remote-eb.c: New memory regime, new info files.
5137 * remote-vx.c: New memory regime, new info files. Now use
5138 separate targets for VxWorks attachment to machine, and
5139 actually running a process under VxWorks, since one has
5140 stack & execution & regs and the other doesn't.
5141 * remote.c: New memory regime, new info files.
5142 * sparc-xdep.c (fetch_core-registers): New memory regime.
5143 * target.c: New routines and support for stacked targets,
5144 new memory regime, new info files regime.
5147 Generalize section handling for an arbitrary number of sections,
5148 including use of the new BFD (binary file) library.
5149 * gdbcore.h: Add struct section_table.
5150 * exec.c (build_section_table): Iterate all sections and
5151 record what gdb needs to know about them.
5152 (exec_command): Use it.
5153 (exec_xfer_memory): Use the table.
5154 (exec_files_info): Print the table.
5155 * core.c (core_file_command, core_xfer_memory, core_files_info):
5157 * source.c (find_source_lines): Use bfd_get_mtime.
5158 * dbxread.c: Quick changes to make it compile with new BFD.
5159 * utils.c (error): Avoid using bfd_error in generic routines.
5161 * core.c (core_fetch_registers): Get from the ".regs" section of
5163 * sparc-xdep.c (fetch_core_registers): Use the .regs info.
5165 * inferior.h (attach_flag): Export.
5166 * infcmd.c (run_command): use new target_create_inferior.
5167 * infrun.c (child_create_inferior): Don't return result.
5168 * Makefile.dist (VERSION): 3.91.4.
5170 Fri Nov 23 28:15:38 1990 John Gilmore (gnu at cygint)
5172 * breakpoint.c (bpstat_num): Handle breakpoints which have
5173 since been deleted, such as temporary breakpoints.
5174 infcmd.c (program_info): ditto.
5176 * core.c (core_file_command): Display the frame where the core
5181 * remote-vx.c (target_command): Merge in target command from
5182 targ-vx.c. A few other cleanups.
5184 * TODO, Projects: Lots more stuff to do...
5186 Fri Nov 23 18:15:38 1990 John Gilmore (gnu at cygint)
5188 Massive changes to wall off the remote-debugging interface
5189 behind a function vector. The port to handle VxWorks targets
5190 is also part of this.
5192 All files: Replace references to renamed functions,
5193 remove references to remote_debugging, remove references to
5194 have_include_file, have_core_file in favor of target_has_stack,
5195 target_has_memory, etc.
5197 * Modularize the breakpoint interface.
5198 breakpoint.h (BREAKPOINT_MAX): New define sets max length of
5199 a breakpoint instruction.
5200 breakpoint.c: struct breakpoint's shadow_contents now sized as
5202 (insert_breakpoints): Vector to target to install breakpoints.
5203 (remove_breakpoints): Vector to target here too.
5204 Remove REMOTE_SA_SPARC kludges and other remote_debugging.
5205 sparc-tdep.c (single_step): Use new breakpoint interface for
5206 the single-step breakpoints.
5207 mem-break.c (memory_insert_breakpoint, memory_remove_breakpoint):
5208 New file, contains routines to insert and remove breakpoints by
5209 reading out the old contents and later replacing them. This is
5210 how ptrace breakpoints work, and many remote systems as well.
5212 * tm-vxworks68.h: New config file, overrides a few things for
5213 Wind River's preferences.
5215 * target.h: New file, for transfer vector used to talk to the
5216 inferior (child, attached, core, exec, remote, etc). All accesses
5217 to the thing being debugged should come through these vectors.
5218 target.c: New file, routines to handle transfer vector.
5219 (various files): Add transfer vectors XXX_ops for the various
5220 targets and pseudo-targets (core files, etc) we support.
5222 * breakpoint.c (bpstat_stop_status): Further explorations of
5223 watchpoints and why things don't work all the time.
5224 (bpstat_alloc): New fn to allocate a bpstat and chain it.
5226 * config.gdb: Only add "source ${srcdir}/.gdbinit" to
5227 the local gdbinit if it doesn't already have it.
5229 * core.c (core_ops): add and install.
5230 Allow core debugging without exec file.
5232 * dbxread.c (free_and_init_header_files): Merge two fns.
5233 (end_symtab): Free named symbol table when a new version comes in.
5234 (read_dbx_symtab): Relocate all kinds of symbols with base
5235 address. First step toward handling different text, data, bss
5237 (add_file_addr_command): Renamed add_file_command.
5238 (add_file_command): Vector to remote handler.
5239 Add "load" as an alias for "add-file" command.
5241 * defs.h: Allow "volatile" to be used in non-ANSI; use it for
5242 non-returning functions.
5244 * exec.c: Add exec_ops, and push it as a target when an exec
5247 * infcmd.c (run_command): Pass executable file name and arg list
5248 separately when starting an inferior. Permit "run" when no exec
5249 file is specified, for VxWorks.
5250 (detach_command): Move to child_detach in inftarg.c.
5252 * inftarg.c: New file. Unix-child-specific routines, and the
5253 child_ops structure.
5255 * inferior.h (registers): Export "registers" as the way for
5256 target dependent register handlers to find gdb's local copy of
5257 the registers. Rename "stop_after_attach" to "stop_soon_quietly"
5258 since it is now used by places that want wait_for_inferior to
5259 handle the grunge but want to see every trap from the inferior.
5261 * inflow.c (create_inferior): Pull out, and merge into infrun.c.
5262 Eliminate remote_debugging hooks in terminal handling.
5264 * infrun.c: Replace start_inferior with child_create_inferior.
5265 Move all the hair of Unix shells and ptrace idiosyncracies into
5266 child_create_inferior, so remote handlers don't have to deal.
5267 Remove running_in_shell. Rename stop_after_attach to
5268 stop_soon_quietly, and use it in a few other places where we want
5269 to just call wait_for_inferior and get control back on the first
5270 trap. trap_expected now never takes a value > 1.
5271 (init_wait_for_inferior): Initialize static vars when a new
5274 main.c (gdbinit): Add new hook for .gdbinit file name, let
5275 it be overridden by config files as GDBINIT_FILENAME.
5276 (DEFAULT_PROMPT): Add new hook for overriding (gdb) prompt.
5277 Both of these are used for VxWorks gdb.
5279 mcheck.c: rename include file "gmalloc.c" to avoid problems
5280 with system include file "malloc.c".
5282 param-no-tm.h: New include file, same as param.h but does not
5283 include the default "tm.h" file. This is used in files where
5284 the target is known, e.g. remote-eb.c or sparc-xdep.c.
5286 param.h: Now just a shell that includes tm.h and param-no-tm.h.
5288 remote-vx.c: New file, VxWorks remote debugging support. Uses
5289 RPC routines that are shared with the target system, in directory
5292 remote.c: Vectorize remote interface.
5294 source.c: Globalize source_path, and make an alias "l" for "list"
5295 since we now have the "load" command.
5297 sparc-xdep.c: Use new param-no-tm.h.
5299 symmisc.c (free_named_symtab): Add new function from Wind River.
5300 However, ifdef it out for now while we think about what it should
5303 tm-sun3.h, xm-sparc.h, xm-sun3.h, xm-symmetry.h: Move
5305 the xm- file, and change its name to CHILD_PREPARE_TO_STORE, since
5306 non-Unix-children handle this with their own code in the target
5309 Makefile.dist: Roll version to 3.92.3. Add vx-share stuff to
5310 source and target lists. Add vx-share to default list of include
5311 directories. Add new files to src and target lists: mem-break,
5312 target, inftarg, remote-eb, remote-vx, targ-vx. Be sure the
5313 ${srcdir} versions of munch and createtags are used.
5315 * valops.c (find_function_addr): Split out of call_function.
5316 (call_function_by_hand): Rename call_function; this function
5317 calls functions in the target by laboriously patching the target
5318 word-by-word with the right stack, args, regs, etc.
5321 Mon Nov 5 17:29:10 1990 John Gilmore (gnu at cygint)
5323 Handle AMD 29000 a bit better.
5325 * remote-eb.c (readchar): Mask received char log to make it readable.
5326 (remote_start): Pass arguments down to executing program.
5327 Make startaddr unsigned.
5328 infrun.c (start_inferior): Accept args, pass them to
5330 infcmd.c (run_command): Pass args down to start_inferior.
5332 * tconfig/am29k-aout, tconfig/am29k-coff: New files specifying
5333 the target object file format.
5334 tm-29k.h: Pay heed to COFF_ENCAPSULATE.
5336 * am29k-pinsn.c (print_insn): Print 0x on hex numbers in disassembly.
5337 am29k-tdep.c (examine_prologue): Better checking of function prefixes.
5339 Sun Oct 7 18:20:45 1990 John Gilmore (gnu at cygint)
5341 * Makefile.dist (VERSION): Roll version to 3.91.9 and freeze.
5342 * TODO: We did a few things, we have more to do though.
5344 * xm-sparc.h (CLEAR_DEFERRED_STORES): Define.
5345 * inflow.c (inferior_died): Clear deferred stores.
5347 * Debug problems with dummy frames and calls to the inferior.
5348 * tm-sparc.h (PUSH_DUMMY_FRAME, POP_FRAME): Move to sparc-tdep.c.
5349 * sparc-tdep.c (do_restore_insn): Simplify.
5350 (sparc_frame_find_saved_regs): Simplify and fix what we find.
5351 (sparc_push_dummy_frame): Simplify and fix what we push.
5352 (sparc_pop_frame): Slightly more hair here, deciding whether
5353 we are restoring a saved PC or returning to a return address in %i7.
5354 * sparc-xdep.c (read_inferior_registers): Debug if valid reg is read.
5356 * utils.c (xmalloc, xrealloc): Return type depends on __STDC__.
5357 * symtab.h (xmalloc): ditto, for obstack_chunk_alloc.
5358 * obstack.h (chunkfun): ditto.
5359 * defs.h (xmalloc, xrealloc): ditto
5361 * utils.c (quit): Grab the terminal from the child if necessary.
5363 * inflow.c (term_status_command): Rename to term_info, change
5366 * sparc-pinsn.c (print_insn): Disassembly prefers real instructions.
5367 (is_delayed_branch): Speed up.
5368 * sparc-opcode.h: Add ALIAS bit to aliases. Fix up opcode tables.
5369 Still missing some float ops, and needs testing.
5371 * Support for input and output radixes other than base 10
5372 * defs.h (input_radix, output_radix): Declare.
5373 * expread.y (yyparse, parse_number): Handle changes of input
5374 radix, and ambiguous names-or-numbers in radixes >10.
5375 * printcmd.c (print_scalar_formatted): Print formatted hex
5376 numbers in varying column widths.
5377 * valprint.c (val_print): Use output_format to print scalar ints.

5379 (set_output_radix): Set output_format from output_radix.
5380 (_initialize_valprint): add `set radix' but leave the others off.
5382 * main.c (execute_command): Let stupid questions be turned off.
5383 (_initialize_main): Handle "set stupidity", etc.
5385 * main.c, inflow.c, inferior.h, frame.h, command.c, defs.h,
5386 sparc-pinsn.c, sparc-xdep.c, value.h, valops.c, values.c: Lint.
5388 Tue Oct 2 11:20:02 1990 John Gilmore (gnu at cygint)
5390 * TODO, Makefile.dist, ChangeLog: Freeze for 3.91.8 release.
5391 bfd stuff is still screwed up, but with some manual work, it
5394 * breakpoint.c (bpstat_do_actions): Start over if a command
5395 proceeds the inferior, since the inferior will have stopped and
5396 will need to have its new stop-actions taken care of.
5398 * dbxread.c (read_struct_type): Expression gives Sun3 4.0.3
5399 compiler fits, simplify it.
5401 * gdb.texinfo (directory command): Doc new dir command.
5402 source.c (directory_command): "dir" now puts things on the front
5403 of the path, moves dups up front, and handles multiple names
5404 on the command line, inserting each one in order. It also
5405 blows away cached line and full_filename info.
5407 * stack.c (backtrace_command): Skip "more stack frames follow"
5410 * Change #ifndef HAVE_VPRINTF to #define MISSING_VPRINTF in
5411 xm-convex.h, xm-hp300bsd.h, xm-isi.h, xm-merlin.h, xm-news.h,
5412 xm-np1.h, xm-pn.h, xm-pyr.h, xm-symmetry.h, xm-umax.h, xm-vax.h.
5413 The only odd one was Gould NP1, which had defined vprintf to
5416 * Merge Ted Goldstein <tedg@Eng.sun.com>'s changes for epoch.
5417 printcmd.c (print_command_1): Pass 'inspect' flag down as a global
5418 variable, inspect_it.
5419 valprint.c (print_string, val_print): Use the global inspect_it
5420 to indicate whether to print in Epoch style or normal style.
5422 Mon Oct 1 23:55:26 1990 John Gilmore (gnu at cygint)
5424 * printcmd.c (call_command): add an alias for the "print" command
5425 which runs expressions and doesn't print the result if void.
5426 (print_command_1): implement it.
5428 * command.c: Remove #if 0'd code. Initialize all the fields
5429 in add_cmd (). Rename do_nothing_command to
5430 not_just_help_class_command, and make it externally visible.
5431 command.h: add user_commands to struct.
5432 * main.c (define_command): Don't overload c->function with a char
5433 string as well as a function pointer.
5435 * eval.c (evaluate_subexp): Reinstall tiemann changes to
5436 calling convention of value_struct_elt () that got dropped in
5439 * tm-sparc.h (FRAME_FIND_SAVED_REGS): move to sparc-xdep.c.
5440 sparc-tdep.c (sparc_frame_find_saved_regs): ditto.
5442 * tm-sparc.h (POP_FRAME): replace some constants with defines.
5444 * sparc-xdep.c (store_inferior_registers): defer stores to regs
5445 until a good time (e.g. when we are about to run the child),
5446 saving ptrace calls.
5447 * infrun.c (proceed): handle DO_DEFERRED_STORES.
5448 * tm-sparc.h: define DO_DEFERRED_STORES.
5450 * sparc-xdep.c (store_inferior_registers): when storing float
5451 registers, don't store stack regs too. When storing the SP,
5452 however, DO store the stack regs too. This fixes a bug in which
5453 the dummy frame is not recognized when a call_function finishes,
5454 because its frame pointer (in the stack regs) was never
5456 (read_inferior_registers): Mark WIM and TBR and FPS and CPS valid
5457 even though we don't know how to read them from an inferior.
5458 valops.c (call_function): Comment about storing SP.
5460 * infrun.c (save_inferior_status): Save away the original bpstat
5461 chain so it can be restored later. Install the copied version for
5462 use by whoever saved the status. It will be blow away by
5463 restore_inferior_status, and the original chain restored. This is
5464 important for people who have pointers into the original.
5466 * breakpoint.c, command.h, copying.awk, dbxread.c, defs.h,
5467 findvar.c, frame.h, obstack.h, obstack.c, inflow.c, value.h,
5468 main.c, printcmd.c, sparc-tdep.c, symtab.c, valprint.c: lint
5471 Fri Sep 28 20:32:46 1990 John Gilmore (gnu at cygnus.com)
5473 * Makefile.dist: Roll version to 3.91.8. Add bfd.h and bfdconfig.h
5474 temporarily to the makefile. Add am29k-opcode.h and WHATS.NEW.
5475 Add stuff.c and kdb-start.c to the OTHERS list for tar files.
5477 Fri Sep 28 19:12:12 1990 John Gilmore (gnu at cygint)
5479 * Merge Mike Tiemann's multiple inheritance changes from Sun.
5480 Store the baseclasses in a type struct starting from array element
5481 0 rather than from the unusual array element 1.
5483 dbxread.c: the above.
5484 (virtual_context): Add
5485 Read new debug information about which virtual function table
5486 a virtual function is from, and store it in fn_field.fcontext.
5488 symtab.h: Add fcontextt. Fix baseclass indices. Typo in
5489 TYPE_FN_FIELD_STATIC_P.
5491 symtab.c: the above.
5492 valops.c: the above. Handle pointer casts of object *'s.
5493 (search_struct_method): Add.
5494 (value_struct_elt): First arg is now a pointer to a value, and is
5497 valprint.c: the above.
5498 values.c (value_virtual_fn_field): Add type arg. Handle
5499 offsetting to the proper object when calling virtual fns.
5501 (baseclass_addr): Add valuep arg.
5503 * README: Document the current state of BFD config (missing).
5504 * TODO, ChangeLog, Makefile.dist: Roll version.
5505 * WHATS.NEW: Add summary of changes since 3.5.
5507 Thu Sep 27 16:23:12 1990 John Gilmore (gnu at cygint)
5509 * dbxread.c (read_struct_type): Clear bit vectors whenever
5511 symtab.c (B_CLRALL): define.
5513 * tm-sparc.h (STORE_RETURN_VALUE): Avoid clobbering types by
5514 using == rather than =. Huh... This fixes the dreaded problem
5515 wherein builtin_type_int becomes TYPE_CODE_FLT.
5517 * core.c (info_files): Show the inferior pid.
5519 * config.gdb: Avoid putting "dir" command into .gdbinit. GDB
5520 already knows how to look in the source directory.
5522 * Remove psymtab hair from many places. Remove duplicated code
5523 for searching symbol tables. Hide psymtabs from most places.
5524 Make it fast to get from a psymtab to its symtab.
5526 blockframe.c (blockvector_for_pc): Remove psymtab hair.
5527 coffread.c (psymtab_to_symtab): Rename to psymtab_to_symtab2.
5528 mipsread.c (psymtab_to_symtab): Rename to psymtab_to_symtab2.
5529 dbxread.c: export psymtab_to_symtab, make it work if called N times.
5530 (psymtab_to_symtab): Rename to psymtab_to_symtab2. Initialize
5531 new symtab completely. New psymtabs get symtab pointer
5532 initialized to zero. Remove MI warning printf.
5533 symtab.h: Comments. Add psymtab to symtab pointer.
5534 (PSYMTAB_TO_SYMTAB): New macro.
5535 symtab.c: use PSYMTAB_TO_SYMTAB. Add psymtab_to_symtab and export it.
5536 source.c: use PSYMTAB_TO_SYMTAB. Remove symtab version and
5538 stack.c (backtrace_command): Avoid pre-pass to read symbols, if
5540 (print_frame_info): Avoid special-casing symbols that have not yet
5543 * source.c (open_source_file): Quick path if we have already
5544 located the source file by its full name.
5546 * symtab.c (lookup_symbol): Use find_pc_symtab rather than
5547 find_pc_psymtab. When a name is found in the misc function
5548 vector, search the symbol table for its mangled name, not the
5549 name that the user typed.
5551 * bfd.h: Fix missing comment terminators, make #endifs match.
5553 * valarith.c (value_less): Handle unsigned int comparisons.
5554 Add FIXME about pointer compares, which assume host and target
5555 pointers are the same.
5557 * command.c (do_nothing_command): lint
5558 dbxread.c: lint. Remove sort_syms. Document C++ visibility info,
5559 fix comments on debug symbol format for visibility. Actually set
5560 visibility of symbols.
5561 main.c (echo_command): lint; use <readline/history.h>.
5562 tm-sparc.h (FRAME_FIND_SAVED_REGS): lint
5563 obstack.h (_obstack_blank): Rearrange pointer math to avoid
5564 pointing past end of allocated memory; saber complains.
5565 obstack.h: Declare the external functions that we use.
5566 valarith.h: use <string.h>
5567 solib.c (solib_add): lint.
5569 Fri Sep 21 17:05:19 1990 John Gilmore (gnu at cygint)
5571 * main.c (initialize_main): Default info_verbose to off, now that
5572 symbol reading is fast.
5573 (quit_command): Avoid clobbering exec_bfd while quitting.
5575 * Initial BFD (binary file diddling library) merger:
5576 coffread.c: Change AOUTHDR to struct exe_hdr.
5578 core.c: initialize initialized data at compile time.
5579 (core_file_command): Move from coredep.c, convert to bfd.
5580 (xfer_core_file): Convert to bfd.
5581 exec.c (exec_file_command): use bfd routines.
5583 mips-tdep.c: Remove exec_file_command and friends.
5586 * coredep.c: (fetch_core_registers) Convert core_file_command to
5587 fetch_core_registers.
5588 mips-xdep.c, sparc-xdep.c, sun3-xdep.c: ditto.
5590 * utils.c: (error): Bogus crap, FIXME, to print bfd errors.
5591 (my_bfd_read): More bogosity, which I don't think we call.
5592 (program_name): Remove this atrocity asap!
5594 Wed Sep 19 13:36:41 1990 John Gilmore (gnu at cygint)
5597 values.c: allocate_repeat_value was not clearing the
5598 optimized_out field.
5599 (value_static_field): minor stylistic fix (wrong macro was used).
5600 valops.c (value_struct_elt_for_address): didn't work for C++
5603 * signame.c (_initialize_signame): Initialize signal names once.
5605 * breakpoint.h, command.c, copying.awk, defs.h, environ.c,
5606 exec.c, frame.h, infcmd.c, inferior.h, main.c, munch, sun3-xdep.c,
5607 symtab.h, tm-29k.h, valprint.c, value.h, values.c: Lint.
5609 * remote-eb.c: Support user-settable baud rates on the serial port.
5611 * tm-sun3.h (PREPARE_TO_STORE): fix typo.
5613 Fri Sep 14 13:28:29 1990 John Gilmore (gnu at cygint)
5615 * tconfig/sun3os4: Remove warning about native assembler,
5616 since it also occurs in the xconfig file.
5618 * findvar.c (registers): Allocate some slop after `registers'
5619 to prevent stray accesses from trashing the next variable.
5621 * tm-68k.h (REGISTER_BYTES): Allocate the right number of bytes
5622 on the sun-3, by changing the #ifdef from `sun3' (which is not
5623 defined by cc) to `sun'. Symptom was trashed builtin_type_XXX
5624 vars, which happened to follow `registers' in the executable.
5626 * readline/history.c (history_search): Heed gcc-2's advice
5627 and parenthesize && inside ||).
5629 * am29k-opcode.h, am29k-pinsn.c, am29k-tdep.c, remote-eb.c,
5630 tm-29k.c: Insert FSF copyright headers.
5632 * remote-eb.c: Better comments.
5634 * Makefile.dist: Update to 3.91.6.
5635 * TODO: note PREPARE_TO_STORE problem.
5637 Thu Sep 13 09:52:33 1990 Jim Kingdon (kingdon at cygint)
5639 * stack.c (frame_info): Only use FRAME_FIND_SAVED_REGS if defined.
5641 * remote.c: Wrap the whole file in #if !defined (SPECIAL_REMOTE).
5643 * infrun.c (wait_for_inferior, at end): Don't set up
5644 prev_* if the inferior no longer exists.
5646 * inferior.h (CALL_DUMMY_LOCATION): New macro, to replace
5647 CANNOT_EXECUTE_STACK.
5648 valops.c (call_function): Use it.
5650 * tm-convex.h: Add CALL_DUMMY_LENGTH for use by PC_IN_CALL_DUMMY.
5652 * inferior.h (PC_IN_CALL_DUMMY): New macro.
5653 infrun.c (wait_for_inferior, 2 places): Use it.
5655 * values.c (value_being_returned): Only use
5656 EXTRACT_STRUCT_VALUE_ADDRESS if defined.
5658 * Move PREPARE_TO_STORE from xm-sun3.h to tm-sun3.h to do the
5659 right thing for remote-eb.c.
5661 * sun3-xdep.c: Remove extraneous call to remote_store_registers.
5662 * sun386-xdep.c, hp300hpux-xdep.c, sparc-xdep.c: Ditto.
5664 * blockframe.c: Put get_frame_saved_regs inside #if !defined
5665 (FRAME_FIND_SAVED_REGS).
5667 * findvar.c ({fetch,store}_registers): Check for
5668 REMOTE_{FETCH_STORE}_REGISTER macro.
5670 * findvar.c (get_saved_register): Add argument lval and
5671 change meaning of argument addr.
5672 findvar.c: Change calls to get_saved_register to reflect
5673 new calling convention.
5674 valops.c (value_assign): Use get_saved_register instead of
5675 find_saved_register.
5677 Sun Sep 2 12:40:20 1990 Jim Kingdon (kingdon at cygint.cygnus.com)
5679 * coffread.c (read_one_sym): Make temp_aux an AUXENT, not
5680 an (uninitialized) pointer to one. Use "&" when passing it
5683 Fri Aug 31 22:57:54 1990 Jim Kingdon (kingdon at cygint.cygnus.com)
5685 * coffread.c (getfilename): Use DGUX x_offset and x_name if
5688 * coffread.c (symbol_file_command): Put semicolon after
5690 Put safe_to_init_tdesc_context in #if defined (TDESC).
5691 Put #ifdef TDESCs in 1st column for non-ANSI cpp's.
5692 coffread.c: #include <sys/stat.h>.
5693 (read_coff_symtab): Typo: in_source_files -> in_source_file.
5694 Add missing ')' in check for "lc%" and friends. Remove
5696 Declare read_one_sym() at top of file.
5697 (read_file_hdr): Put in extra #ifdefs so MC68MAGIC and
5698 MC68WRMAGIC can have the same value without causing a duplicate
5701 Thu Sep 13 15:55:36 1990 John Gilmore (gnu at cygint)
5703 * Allow a Makefile to be built without building the
5704 tm and xm file links that screw up builds in subdirectories.
5705 This is done with `config.gdb none', then you can do things
5706 like `make gdb.tar.Z'.
5707 * tconfig/none: Config file for no target system
5708 * xconfig/none: Config file for no host system
5709 * config.gdb: If no TM or XM files are called out by the
5710 host or target file, don't make links for them.
5712 * cplus-dem.c: Add documentation.
5714 * dbxread.c (read_ofile_symtab): Turn a fatal error into a
5715 simple error, so the user's gdb doesn't crash due to some object
5716 file problem (e.g. somebody is rebuilding the file out from under
5719 * printcmd.c (print_address_symbolic): demangle the symbol.
5721 * Makefile.dist (OTHERS): Remove tdesc-lib because it has
5722 Motorola copyrights in it. Make "make gdb.tar.Z" work.
5723 (alldeps.mak): sort and uniq all results from this; duplicates
5724 hose gdb.tar.Z link building. Remove RCS files from
5725 tconfig and xconfig. Add config files for sun386. Add
5726 a few odd files to OTHERS and HFILES.
5728 Mon Sep 10 21:20:24 1990 John Gilmore (gnu at cygint)
5730 * Makefile.dist: Pull solib.c to tconfig/sun?os4.
5731 Roll version number to 3.91.5. Make lint work in bindir.
5733 * README: Document cross-debugging and new file structure.
5735 * blockframe.c: Lint. Include "value.h" to declare read_register.
5736 (find_pc_partial_function): remove duplicate line.
5738 * command.h: Lint. Declare error_no_arg and dont_repeat.
5740 * tm-news.h: Remove inadvertently duplicated stuff.
5742 * mipsread.c: Remove cache_pc_function stuff, now done cleanly.
5743 Clean up usage of misc_function_type. Declare some CORE_ADDRs.
5745 * config.gdb: Allow `config.gdb host target' form. Clean
5746 up previous change that printed bogus messages when you just said
5749 * core.c: #include "command.h" for lint.
5752 * main.c: Remove some casts of enums. Lint.
5759 * printcmd.c (initialize_printcmd): Fix thinko in inspect cmd.
5761 * sparc-tdep.c (isannulled): Take instruction as parameter, don't
5762 read it from memory. This will allow us to save ptrace calls
5763 eventually. Changed caller single_step too.
5765 * sparc-xdep.c (fetch_inferior_registers): Avoid reading regs
5766 that we aren't going to use, saving many ptrace calls, especially
5767 when watchpointing or single stepping. Use some #define's for
5769 (store_inferior_registers): Ditto.
5770 (core_file_command): Use some #define's for constants.
5772 * tm-sparc.h: Add #define's for some register numbers, so we
5773 can eliminate the use of random constants in sparc-xdep.c.
5775 * stack.c (frame_command, print_frame_info, up_command,
5776 down_command) Remove frame_changed, since it
5777 causes a bug and doesn't seem to do anything useful. In some
5778 places it was used as a flag, in others as a stack level (?).
5780 * utils.c: Use MISSING_VPRINTF rather than HAVE_VPRINTF, so the
5781 default is to use the portable (vprintf) version rather than the
5783 * xm-news.h (MISSING_VPRINTF): Add.
5785 * valprint.c (val_print): Demangle fancy vtbl printouts. Lint.
5787 Sat Sep 8 00:24:12 1990 John Gilmore (gnu at cygint)
5789 * Remove stuff that forces -Bstatic linking of gdb, and warnings
5790 about linking debugged programs -Bstatic in the sun?os4 config
5791 files in tconfig and xconfig subdirectories.
5793 * main.c (main): Remove unreached exit(0) now that we exit
5796 * Create TODO file for online bug list. There are too many
5797 "little" bugs to keep track of on paper.
5799 * Change Projects file to refer to bug-gdb@cygnus.com
5800 rather than kingdon@ai.
5802 Fri Sep 7 23:35:15 1990 John Gilmore (gnu at cygint)
5804 * Makefile.dist (VERSION): 3.91.4 now.
5806 * symtab.c (init_misc_bunches): Rename from init_misc_functions.
5807 (condense_misc_bunches): Add sanity check that misc_count is
5808 the same as the number of symbols in the bunch.
5810 * coffread.c: rename init_misc_bunches. Pass an argument
5811 to condense_misc_bunches (a zero).
5813 * dbxread.c (partial_symbol_file_read): Call init_misc_bunches
5814 every time we are called; don't rely on our caller to do it.
5815 (add_file): Remove call to init_misc_bunches.
5817 * mipsread.c: Only warn, don't error, if unknown symbol types.
5818 This keeps an old gdb from falling on its face if it sees newly
5819 extended symbol info. Rename init_misc_bunches.
5821 Fri Sep 7 22:58:15 1990 John Gilmore (gnu at cygint)
5823 * Merge in changes from Per Bothner for DECstations and other
5824 MIPS stuff. The rest is Bothner speaking:
5826 The next message is a merger of Alessando Forin's mips port with
5827 mine. I've tried to use my good if biased judgment to get
5828 the best of both. It *does* need testing.
5830 Some of the changes are general, *not* mips-specific.
5833 Didn't believe in little-endian bit order.
5834 There are still inconsistencies about whether flags
5835 like BITS_BIG_ENDIAN are integer (#if ...) or
5836 boolean (#ifdef ...). I tried to paper over them.
5838 dbxread.c,coffread.c,mipsread.c,symtab.c,symtab.h:
5839 Moved some misc_function code that was common to
5840 {dbx,coff,mips}read.c to symtab.c.
5841 In the process, I think I cleaned things up a bit.
5842 At the same time, moved obsavestring and obconcat to symtab.c.
5845 Removed obsolete condense_addl_misc_bunches (use
5846 condense_misc_bunches(1) instead).
5849 Needed to include <sys/dir>, at least on DECstations.
5851 valops.c, mips-tdep.c, tm-mips.h:
5852 Added PUSH_ARGUMENTS macro to support funny argument-pushing
5853 conventions (when STACK_ALIGN is insufficient).
5854 Needed on mips, where doubles need 8-byte alignment,
5855 but ints only need 4.
5858 Removed cruft that was not being used.
5859 Merged in many fixes (most from Frank Yellin, fy@lucid.com).
5862 Print $ before register-names (I think that makes things a little
5864 Never print two instructions, even if one delays.
5865 Removed hex-disassemble set_cmd. (This is not mips-specific,
5866 so I think the argument is whether it is generally worthwhile or not.
5867 I'm inclined to think not, given how easy it is to
5868 convert between radixes in gdb.)
5871 This is basically Alessando's code.
5872 It doesn't use obstacks; I changed it to use obstacks
5873 in a few minor places where using malloc causes a
5874 memory leak. (Probably, more places could/should be changed.)
5875 I added record_misc_function where it was missing.
5876 In symbol_file_command and add_file_command, I tried
5877 to make the code consistent with more recent versions.
5878 Minor sylistic changes in parse_procedure.
5879 Make a .gdbinfo. psuedo-symbol point back to the real
5880 procedure symbol (using the isym field).
5883 This is basically from my port, but with a lot of details
5884 and a number of routines merged in from Alessando's version.
5885 I basically used my code "raw" backtrace (use heuristics
5886 from the actual code, rather than symbol table info) - though
5887 the idea is Alessandro's. I feel my code is a little cleaner
5888 here, particularly in being a little more flexible, such as being
5889 able to handle gcc-produced code (which it now can).
5890 It also doesn't do frame caching (which is not useful
5891 more recent gdb versions).
5892 I also used my code for push_/pop_dummy, more or less.
5893 I tried to incorporate AF's code for testing sigtramp
5894 while backtracing; I probably got it wrong.
5895 Added mips_print_register, which tries to scrunch as much
5896 information as possible on a screen...
5897 Removed the skip-prologue set_cmd. As with hex-disassemble (see
5898 under mips-pinsn.c), I don't see anything mips-specific here,
5899 and I don't see it being all that useful anyway.
5902 Added a $fp psuedo-reg distinct from $fp (nice for gcc).
5903 Use more register names (rather than hard-cases numbers).
5905 Thu Sep 6 18:33:15 1990 John Gilmore (gnu at cygint)
5907 * Hack up 3.90.11 changes:
5909 * Makefile.dist (depend): parameterize $(GCC).
5910 Add solib.c and solib.o.
5911 (readline): Fix vpath for both absolute or relative SRCDIR.
5913 * blockframe.c: Fix from Schaefer@asc.slb.com for shared libs.
5914 Also, let the part I didn't understand at least compile so
5915 I can test the rest. FIXME.
5917 * dbxread.c: Fix thinko using strcmp.
5918 (init_psymbol_list): declare static.
5919 (partial_symbol_file_open): Comment cleanups better, avoid
5920 cleaning up the string table since the caller will do that.
5921 Move the stat for mod time into symbol_file_command, temporarily.
5922 (There should be a mod time for each symbol file, eventually,
5923 to control its rereading. FIXME.)
5925 * infptrace.c (PT_WRITE_D): use same value as PT_WRITE_I for
5926 SunOS, which gives error for shared libs otherwise. (From
5927 Schaefer, probably FIXME needs work for portability.)
5929 * solib.c: Move #include "param.h" to work.
5930 Lowercase all the Uppercase Letters In the Messages.
5931 (find_solib): Clean up inferior_so_name for debug printouts.
5932 Allow no argument, to mean all shared libraries.
5934 * symmisc.c: include param.h to get CLEAR_SOLIB.
5936 Wed Sep 5 18:00:08 1990 John Gilmore (gnu at cygint)
5938 * Merge in Kingdon's changes from FSF: the diffs from 3.90.9
5939 to 3.90.11. ChangeLog entries below are from this.
5941 Wed Jun 13 09:17:39 1990 Jim Kingdon (kingdon at mole.ai.mit.edu)
5945 * Makefile.dist (HFILES): Add tm-sunos.h.
5947 Tue Jun 12 16:15:26 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5951 * Makefile.dist (gdb.tar.Z): Change linking of config so it works.
5953 Thu Jun 7 16:22:27 EDT 1990 Jay Fenlason (hack@ai.mit.edu)
5955 * sparc-opcode.h Added single-operand version of rett.
5957 Mon Jun 4 18:12:31 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5959 * m-sparc.h (REG_STRUCT_HAS_ADDR, STRUCT_ARG_SYM_GARBAGE):
5960 Put parens around gcc_p in expansion.
5962 Thu May 24 15:44:51 1990 Jim Kingdon (kingdon at mole.ai.mit.edu)
5964 * utils.c (lines_to_list): Return 10 if lines_per_page == 0.
5966 Wed May 23 16:36:04 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5968 * Changes for Sun shared libraries:
5969 blockframe.c (find_pc_partial_function): If a non-text symbol
5970 is found, set *address = pc - FUNCTION_START_OFFSET.
5971 breakpoint.c (insert_breakpoints) [DISABLE_UNSETTABLE_BREAK]:
5972 Disable breakpoints instead of giving an error.
5973 source.c (select_source_symtab): Initialize cs_pst.
5974 symmisc.c: Call CLEAR_SOLIB if defined.
5975 symtab.h: Make text{low,high} CORE_ADDR not int.
5976 (psymtab): New field addr.
5978 dbxread.c: Move DECLARE_FILE_HEADERS outside functions.
5979 (record_misc_function): Give correct type for N_DATA symbols.
5980 (condense_misc_bunches): do "misc_function_count = j" regardless
5982 Take code which is shared between symbol_file_command and
5983 add_file_command and put it into partial_symbol_file_{open,read}.
5984 Split add_file_command into add_file_command and add_file.
5985 Make psymtab_to_symtab read in the string table if the file
5987 Two new parameters to read_dbx_symtab and start_psymtab.
5988 tm-sunos.h: New file.
5990 Tue May 22 17:43:03 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5992 * infcmd.c: Change cont_command to continue_command and "cont"
5995 Mon May 21 14:41:41 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5997 * breakpoint.c (enable_breakpoint): Get value of watchpoint.
5999 * defs.h [sparc]: Use <alloca.h> regardless of __GNUC__.
6001 * values.c (USE_STRUCT_CONVENTION): Check for structures of
6002 size 1,2,4,8 rather than size < 8.
6004 * dbxread.c (dbx_lookup_type): Do f->length *= 2 as many times
6005 as necessary, not just once.
6007 * sparc-opcode.h: Add a bunch of new opcodes which Sun as supports.
6009 Thu May 17 15:04:09 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
6011 * {t,x}m-sun386.h, sun386-xdep.c, {x,t}config/sun386
6013 * tm-news.h: Add CALL_DUMMY_*.
6015 * tm-68k.h: Remove duplicate comment at FRAME_FIND_SAVED_REGS.
6017 * config.gdb: In list_host, list_target, use ${i}, not $i.
6019 Tue May 15 21:27:12 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
6021 * source.c (find_source_lines) [BROKEN_LARGE_ALLOCA]: Use xmalloc.
6023 * sparc-opcode.h: Change all store floating-point state register
6024 instructions to have the right match & lose fields.
6026 Sat May 5 12:39:18 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
6028 * Makefile.dist: Move -I${srcdir} to GLOBAL_CFLAGS and pass
6030 config.gdb: If srcdir != ., create readline directory and
6031 copy a makefile into it.
6033 * wait.h, infrun.c: Change WRETCODE to WEXITSTATUS for
6034 consistency with POSIX.
6036 * breakpoint.c (bpstat_stop_status): Disable watchpoint
6037 when we exit its exp_valid_block.
6039 Tue Sep 4 11:46:46 1990 John Gilmore (gnu at cygint)
6041 * Makefile.dist: Bump version to 3.91.3.
6043 * Clean up handling of breakpoint commands (somewhat).
6044 Prompted by Tiemann bug report "cont 10" doesn't work any more.
6046 inferior.h: Add breakpoint_proceeded to inferior status struct
6047 and globals; save it and restore it.
6048 (clear_breakpoint_commands): Cleanup, remove old #define.
6050 infrun.c (clear_proceed_status): Set breakpoint_proceeded.
6051 (save_inferior_status, restore_inferior_status): handle it also.
6052 (proceed): Remove earlier code that set breakpoint_proceeded.
6053 It is now set only in clear_proceed_status.
6054 (clear_proceed_status): Cleanup, use bpstat_clear rather
6055 than clear_breakpoint_commands. No callers need the stop_bpstat
6056 between clear_proceed_status and proceed.
6058 infcmd.c: Add breakpoint_proceeded definition and comment.
6059 (cont_command, jump_command, signal_command): Move call to
6060 clear_proceed_status right next to call to proceed.
6062 breakpoint.c (bpstat_do_actions): Avoid clobbering our
6063 caller's argument while running down the chain of breakpoints.
6064 Use new variable "breakpoint_proceeded" to determine when
6065 a command that it executes moves the inferior past the
6067 (bpstat_clear): Handle NULL argument.
6068 (bpstat_clear_actions): Avoid useless call to
6069 breakpoint_auto_delete.
6070 (delete_breakpoint): Clean up bpstat's that are pointing to
6071 the deleted breakpoint from the stop_bpstat chain.
6072 (breakpoint_auto_delete): Simplify.
6074 * Clean up handling of EOF, error on stdin, etc. This was
6075 prompted by a network problem that caused gdb to go into an
6076 infinite loop filling up its malloc'd memory.
6078 main.c (return_to_top_level): Cleanup: call bpstat_clear_actions,
6079 not clear_breakpoints_commands, which is now gone.
6080 (main): If command_loop returns (e.g. from EOF on stdin), do
6081 a quit_command (looping back to command_loop if quit_command
6082 doesn't really quit).
6083 (command_loop): check result from command_line_input and
6084 exit if it returns NULL, rather than passing the NULL to
6086 (gdb_readline): Free malloc'd result space before returning
6089 * utils.c (query): Handle C-d to mean "yes", just as if the
6090 input was not a terminal. Also avoid infinite loop if EOF
6091 occurs in mid-input-line before newline. This allows
6092 query to be used at EOF on stdin with reasonable results.
6094 * infrun.c (proceed): Set breakpoint_proceeded.
6096 * values.c (value_as_long): Avoid infinite recursion for enums.
6097 (_initialize_values): Fix typo in help msg (kingdon).
6099 * Makefile.dist (RL_LIB): Use RL_LIB_DEP for dependencies,
6100 RL_LIB for linking. This allows -lreadline for linking
6101 and nothing for dependencies, once readline is a real library.
6103 * config.gdb: Jim Kingdon: give useful error message if the
6104 host or target type is not recognized.
6106 * defs.h (alloca): SPARC <alloca.h> does not declare alloca,
6107 it just defines it. Dumb, but deal with it.
6109 * Jim Kingdon suggests:
6110 in xconfig/sun3os4, CFLAGS should be XM_CFLAGS.
6112 Wed Aug 29 18:03:27 1990 John Gilmore (gnu at cygint)
6114 * Makefile.dist (VERSION): Bump version # to 3.91.2.
6116 * Clean up Bothner's changes.
6118 * blockframe.c (clear_pc_function_cache): New function.
6119 * blockframe.c: remake cache_pc_function_* static.
6120 * dbxread.c (symbol_file_command): remove references to
6121 cache_pc_function_* variables.
6122 * dbxread.c (read_struct_type): Use VOFFSET_STATIC.
6123 * printcmd.c: Avoid kludging a global variable (addressprint)
6124 to avoid printing the address of a string twice. Instead,
6125 pass the format letter 's' down low enough that it can be seen
6126 to avoid this problem.
6127 (print_formatted): Pass format arg to value_print.
6128 (restore_addressprint): Remove function.
6129 (do_examine): Avoid hacking addressprint, cleanups and such.
6130 (print_frame_args): Add a comment to a Bothner change.
6131 * symtab.h: define VOFFSET_STATIC and use it instead of "-1".
6132 * symmisc.c (free_all_symtabs): Call clear_pc_function_cache
6133 to wipe out the values cached in blockframe.c.
6134 * symtab.c (find_method): Add comment saying how big you must
6135 allocate to be "big enough". Per being terse again.
6136 * valprint.c (val_print): Handle format letter "s" to print
6137 strings without addresses. Add comment to vtbl printing code
6138 which casts with wild abandon. Rearrange reference-printing
6140 @0xaddr: value (print w/addressprint)
6141 value (print w/~addressprint)
6142 @0xaddr (parameter lists w/addressprint)
6143 or nothing (parameter lists w/o addressprint)
6145 Tue Aug 28 10:47:18 1990 John Gilmore (gnu at cygint)
6147 * Merge more changes from Per Bothner:
6149 Gdb's handling of TYPE_CODE_REF was so counter-C++ (and otherwise
6150 annoying) that I tried to improve it. Here are my suggestions.
6152 These patches all attempt to handle TYPE_CODE_REF (as in C++) better.
6155 Do automatic de-reference when taking the address of a reference.
6157 Don't deref_ref when printing parameter lists.
6159 More attempts at treating refernences properly.
6161 In val_print, if deref_ref==0, don't print dangling " = ".
6163 Add COERCE_REF macro, which de-references an REF.
6165 * Merge changes from Per Bothner:
6167 * Fixed (Sony news)-specific configuration problems.
6168 * Fixed other problems with using vanilla pcc and libc (enum problems;
6169 assumption that vsprintf exists).
6170 * Some major speed-ups (finc_pc_partial_function now caches a match;
6171 parsing avoids duplicate symbol_lookup calls).
6172 * Changed handling of baseclasses (no longer use baseclasses field
6173 of struct type, use the first n_baseclasses fields instead).
6174 * Various minor changes/fixes, most C++-related.
6177 Cache the most previous match from find_pc_partial_function.
6178 (Save both low and high ends of matching function's pc range.)
6179 This speeds up the loop of infrun.c:wait_for_inferior quite
6180 a bit, and makes step/next commands much zippier.
6182 Added an enum->int cast (otherwise, some compilers barf).
6184 No longer set baseclass offset to 0, since multiple
6185 inheritance now mostly works.
6186 Added a number of casts, to shut up compiler warnings
6187 (after stabs where made enums, not ints).
6188 When discarding a symbol table (in symbol_file_command),
6189 must clear the cache introduced in blockframe.c.
6190 Don't convert $vtbl_ptr_type to vtbl any more.
6191 Get rid of TYPE_BASECLASEES and baseclass_vec (see also symtab.h).
6192 Mask off sign bit emitted by g++ for virtual table offset.
6193 Set voffset to -1 (not 1) for static member functions.
6195 Changed parsing/lexing of names to avoid doing symbol lookup twice
6196 (once when lexing to determine symbol class, once for real).
6197 Now only call symbol_lookup once. Fields of 'this' win especially big.
6199 Subpress printing addr twice in the case of 'x/s addr'.
6201 lookup_basetype_type is no longer used.
6202 Add find_methods as recursive helper function to decode_line_1.
6203 This allows multiple inheritance to work.
6204 Also, once one or more matches has been found, do not look in
6205 base-classes. (Baseclass methods would be overridden, anyway.)
6207 Removed baseclasses array in struct type.
6208 Instead of using baseclasses[i], use fields[i-1].
6209 Added virtual_field_bits[i] to indicate if the i'th baseclass is virtual.
6210 Changed sign convention of voffset (previous was inconsistent).
6212 Some macros (CALL_DUMMY and relatives) were missing. Put them back.
6214 Used to assume existence of vsprintf. Re-written to not need it
6215 if HAVE_VPRINTF is undefined.
6217 typecmp was too pessimistic. Made it less so.
6219 Don't print space after address.
6220 If vtable points to a misc symbol (with 0 offset), print it,
6221 since that indicates the actual class of the object.
6222 Changed ype_print_derivation_info to use new inheritance
6223 scheme (without baseclasses vector).
6225 In value_primitive_field, fixed some bugs left over from previous set of fixes.
6226 Also, changes needed because TYPE_BASECLASSES were removed.
6228 REGISTER_U_ADDR didn't work for PC. Rewrote to use an array.
6230 Tue Aug 21 20:08:54 1990 John Gilmore (gnu at cygint)
6233 If there is no path set, and the symbols don't indicate what directory
6234 a file was compiled in, look in the current directory. But either
6235 a path or a known compilation directory will prevent this.
6238 Three independent bug fixes:
6239 * Remove the #if 0 block that breaks some stuff.
6240 * SunOS 4.1 fixed the promoted-parameter-wrong-addr bug in Sun C;
6241 adapt gdb to either SunOS 4.0.* or 4.1.
6242 * MAX_OF_TYPE and MIN_OF_TYPE thinko. By tedg@sun, I think.
6245 Instantiate the class T when looking for methods in it. (Tiemann@sun)
6248 (type_print) Demangle the name being printed.
6249 (type_print_base) Handle botched demangling without coredump (tiemann).
6252 (check_stub_method): Document routine.
6253 (tiemann) fix bug for no-arg functions
6254 Avoid clobbering beyond end of malloc'd storage.
6255 Terminate the argument list properly.
6257 Sat Aug 18 01:29:59 1990 Per Bothner (bothner@cs.wisc.edu)
6259 * Changes merged by John Gilmore:
6262 In breakpoint_1, use new print_address_symbolic instead
6263 of find_pc_partial_function. (This forces use of assembler-level
6264 addresses, and avoids misleading non-mangled source-level names.)
6266 Generalize ansi argument such that -1 means skip arglist totally.
6267 Removed global variable print_ansi_qualifiers (which made
6268 code non-reentrant), in favor of extra explicit arguments
6269 to internal routines.
6271 Add new helper function print_address_symbolic.
6272 Use find_pc_misc_function instead of find_pc_partial_function
6273 (since we want assembler-level symbols here).
6275 Print unknown function as just "f (...)", not "f (...) (...)".
6276 Use new fputs_demangled explicitly.
6278 Fixed a typing violation (problem: value.h cannot be imported
6279 without renaming many variable in this file).
6280 lookup_symbol: If no matching misc_func, look for a C++-mangled name.
6281 decode_line_1: Moved forward some never-reached code.
6282 Made decode_line_2 skip function prologues correctly.
6284 fputs_filtered should not demangle by default.
6285 Add new fputs_demangled to demangle on demand..
6287 Change value_struct_elt to use value_primitive_field (using recursive
6288 utility function search_struct_field). This allows foo.bar to work
6289 for multiple inheritance (so far only for data fields).
6290 Change check_field in the same way (recursive helper function
6291 to support multiple inheritance).
6292 (Note: there are more of these problems that I haven't fixed.
6293 Any code that says TYPE_BASECLASS (t, 1) is probably wrong.)
6294 value_of_this: 'this' symbol name is now just "this", note "$this".
6296 Don't print static members.
6297 Avoid printing "members of <type>" if there are none.
6298 Simplified type_print_derivation_info by merging duplicate code.
6299 Remove useless blank lines in type_print_base (ptype command).
6301 Added declaration of new routine value_primitive_field.
6303 Added value_primitive_field which is generalized version of
6304 value_field that can handle multiple inheritance (non-zero offsets etc).
6305 Re-implemented value_field to call value_primitive_field.
6307 Fri Aug 17 23:33:44 1990 John Gilmore (gnu at cygint)
6309 * infcmd.c -- insert else to avoid 'delete env' coredump when you
6310 delete the whole environment. Karl Berry reported the bug.
6311 * source.c - fix openp to avoid //'s in filenames, which
6312 trigger an Emacs bug causing it to not be able to find files
6313 when running gdb in a window.
6314 * dbxread.c - zap the #if 0 that botches the add-file code.
6315 It seems to work a lot better without all the code commented out.
6317 Fri Jul 20 16:58:46 1990 John Gilmore (gnu at cygnus.com)
6319 * Merge Tiemann's and Ted Goldstein's changes, detailed below,
6322 Tue Jul 17 19:34:33 1990 Ted Goldstein (tedg at golem)
6324 * Makefile - added a ${CFLAGS} to a couple of entries,
6325 added remote-sa.sparc.c
6326 * added remote.sa-sparc.c, a modification of remote.c
6327 which conducts a dialog directly with the SparcStation prom.
6328 * breakpoint.c, infrun.c, sparcdep.c added
6329 remote_insert_breakpoint(), and remote_remove_breakpoint()
6330 to breakpoint.c instead of directly writing breakpoint instructions.
6331 * sparcdep.c on remote_debugging,there is no need
6332 to remove signle step breakpoint instructions.
6333 * main.c added "-epoch" flag and "int epoch_interface" to main.c
6335 * printcmd.c - epoch interface sends lisp expressions to open up
6336 epoch windows on inspection.
6337 * valprint.c - added arrayprint, and addressprint and made adding
6338 format controls easier
6339 * wait.h added a couple of undef's because we were getting
6340 complaints about WSTOPSIG and WTERMSIG begin redefined.
6343 Wed Jul 4 05:27:51 1990 Michael Tiemann (tiemann at masham)
6345 * symtab.c (decode_line_1): Add support for handling method stubs
6346 in the type information.
6348 Tue Jul 3 09:39:18 1990 Michael Tiemann (tiemann at masham)
6350 * values.c (baseclass_addr): Run loop from INDEX+1 to
6351 N_BASECLASSES; otherwise, we can still get into a loop.
6352 @@ This should be restructured to use a cleaner search strategy.
6354 Sun Jul 1 12:28:51 1990 Michael Tiemann (tiemann at masham)
6356 * dbxread.c (define_symbol,read_type): Grok GNU C++'s new
6357 abbreviation "Tt" for tags which have the same name as their
6360 Fri Jun 29 01:03:46 1990 Michael Tiemann (tiemann at masham)
6362 * symtab.c (list_symbols): add ability to set breakpoints on all
6363 the functions which match a particular regular expression.
6365 Tue Jun 26 04:26:29 1990 Michael Tiemann (tiemann at masham)
6367 * cplus-dem.c (cplus_demangle): New parameter ANSI says whether we
6368 should print ANSI qualifiers (such as `const' and `volatile').
6369 All callers changed to call with ANSI == 1, except from
6370 `check_method_stub', which uses old-style syntax.
6372 * symseg.h (struct fn_field): Remove unneccessary `args' field.
6373 * symtab.h (TYPE_FN_FIELD_ARGS): Redefined.
6375 * values.c (check_stub_method): New function.
6377 * cplus-dem.c (do_type): Handle "long long" (encoded as 'x').
6379 * dbxread.c (read_type): Handle new GNU C++ method type stubs.
6380 * valprint (type_print_base): Ditto.
6382 * symtab.c (gdb_mangle_typename): New function.
6384 Tue Jun 5 00:18:43 1990 Michael Tiemann (tiemann at gzilla)
6386 * breakpoint.c (catch_command): New function. Provides a
6387 mechanism to set breakpoints based on catch clauses.
6388 (disable_catch): Similar, but disables breakpoints on catch
6390 (delete_catch): Similar, but deleted breakpoints on catch clauses.
6392 Sun Jun 3 22:54:08 1990 Michael Tiemann (tiemann at gzilla)
6394 * blockframe.c (blockvector_for_pc): New function.
