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

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

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

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

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

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

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

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

775 generic routines for calling inferior functions.
777 * blockframe.c (inside_main_scope, inside_entry_scope): New.
779 * copying.awk: Filter formfeeds out of copying & warrantee.
780 Make them available as `show copying' and `show warrantee' also.
781 * main.c (print_gnu_advertisement): Advt `show' commands.
783 Thu Oct 10 17:25:47 1991 John Gilmore (gnu at cygnus.com)

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

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

928 Fri Sep 20 16:10:52 1991 John Gilmore (gnu at cygnus.com)
932 * Makefile.in (VERSION): Set to 4.1.
933 * language.c (set_language_command): Print useful help message,
934 and restore the language string after giving help.
935 * valprint.c (typedef_print): Print typedef in C or M2.
936 * symtab.c (list_symbols): Use it.
937 * main.c (main): Avoid any output before (gdb) prompt when -q.
938 * language.c (set_language_command): Handle errors by restoring
939 the language string to its current state (fix from A. Beers).
940 * doc/gdbint.texinfo: Roll in information from README. Rearrange
941 "how to install" and "how to print the doc" stuff so it drops
943 * configure.in: Rename rtpc CPU to romp to match config.sub.
944 * README, WHATS.NEW, TODO: Update for gdb-4.1.
946 Fri Sep 20 17:39:14 1991 Roland H. Pesch (pesch at cygnus.com)
948 * doc/gdb.texinfo: Updates from ChangeLog. set/show write,
949 autoloading shared libs, copyright etc on GDB startup, clean up $_
950 and $__ index refs, set/show listsize and related updates to list
951 cmd. New host/target configs.
953 Fri Sep 20 15:46:00 1991 Roland H. Pesch (pesch at cygnus.com)
955 * doc/Makefile: generate aux version-no file doc/gdbVN.m4
956 from main Makefile.in version definition
957 doc/gdb.texinfo: use version recorded in doc/gdbVN.m4 for current
959 Makefile.in (setup-to-dist): generate doc/gdbVN.m4
961 * doc/gdb.texinfo: merge new language-switching and lang-specific
964 Fri Sep 20 15:00:57 1991 Per Bothner (bothner at cygnus.com)
966 * mcheck.c: Add __ONEFILE kludge to allow compilation by non-ANSI
967 compilers (which may lack stddef.h).
969 Fri Sep 20 13:29:42 1991 John Gilmore (gnu at cygnus.com)
971 * dbxread.c (read_dbx_symtab, process_one_symbol): N_FN and
972 N_WARNING are the same except for the N_EXT bit, so just use their
973 values alone, rather than OR-ing them with N_EXT.
975 Fri Sep 20 12:27:55 1991 Stu Grossman (grossman at cygnus.com)
977 * mipsread.c (parse_lines): Deal with negative extended line
980 * c-exp.y, m2-exp.y: #define yyerrflag and yynerrs to avoid
981 global symbol conflicts.
983 Fri Sep 20 02:28:15 1991 John Gilmore (gnu at cygnus.com)
985 * .gdbinit: Move 'set complaints' to top, so it runs even in
986 case we aren't debugging GDB.
987 * language.c (_initialize_language): Fix type check and range
988 check documentation strings.
989 * utils.c (!HAVE_VPRINTF): Define vfprintf as a function, so
990 language.c can use it. (Though language.c should really not be
991 handling warnings/errors the way it does, FIXME.)
992 * symtab.c (lookup_primitive_type): const lint.
994 Bugfix from Peter Schauer:
995 * source.c (lines_to_list): Make signed, to avoid comparison
996 going unsigned and complaining that -3 is too high for 21 lines.
997 * stack.c (lines_to_list): Ditto.
999 Thu Sep 19 23:33:41 1991 John Gilmore (gnu at cygnus.com)
1001 * Makefile.in (HFILES): Add minimon.h.
1002 (VERSION): Roll version number to 4.0.95.
1003 (gdb.tar.Z, make-proto-gdb.dir, setup-to-dist, gdb-XXX.tar.Z):
1004 New rules for building distributions. Normal distribution
1005 is built by doing `make -f Makefile.in gdb.tar.Z' in the directory
1006 one level up from here; it calls make-proto-gdb.dir to build a
1007 directory `proto-gdb' which is an image of the release. The old
1008 `gdb.tar.Z' rule still works too.
1009 * config.sub, configure: Roll in latest from ..
1011 Thu Sep 19 17:41:24 1991 Roland H. Pesch (pesch at cygnus.com)
1013 * doc/gdbint.texinfo: Reorder contents; reorganize new-host,
1014 new-target, and new-config chapters; fix minor typos; come closer
1015 to usual GNU markup conventions for @file @samp @code @var.
1017 Thu Sep 19 17:04:12 1991 Per Bothner (bothner at cygnus.com)
1019 Patches from Peter Schauer <pes@regent.e-technik.tu-muenchen.de>:
1020 * mipsread.c (parse_partial_symbols): Enter the name of all
1021 structs/unions... into the psymtab so we can access them if the
1022 symtab is not read in.
1023 * mips-tdep.c: Remove some unneeded #includes.
1024 * xconfig/dec3100: Add HAVE_STRSTR.
1026 Thu Sep 19 15:14:23 1991 John Gilmore (gnu at cygnus.com)
1028 * Makefile.in: Circumvent Sun Make bug on *-exp.tab.o.
1029 * c-exp.y, m2-exp.y: Lint.
1030 * m2-exp.y: Avoid using yytname[] which is a Bison-ism.
1031 * valprint.c (val_print_fields): Check for stub type.
1032 * mipsread.c (_initialize_mipsread): Avoid using
1033 builtin_type_void at initialize time.
1034 (mipscoff_symfile_read): use it now.
1036 Wed Sep 18 15:55:51 1991 John Gilmore (gnu at cygnus.com)
1038 Merge multiple-language support, and partial Modula-2 support,
1039 from Andrew Beers <beers@cs.buffalo.edu>.
1041 * i387-tdep.c: New file, consolidates most 80387 support,
1042 and eliminates host dependency on double<->extended conversions.
1043 * i386-xdep.c, symm-xdep.c: Remove most 387 support.

1061 (process_coff_symbol): #if 0'd for functions and params as above.
1062 (read_enum_type): Recognize Modula-2 BOOLEAN.
1063 * symtab.c (add_param_to_type): #if 0'd function to add a

1070 hex with local_hex_string for Modula-2 support.
1072 * breakpoint.c (breakpoint_cond_eval): Use new value_true to test

1075 * parse.c: New file with the common code remains of expread.y.
1076 * parser-defs.h: New file with common declarations from expread.y.

1101 * expression.h (enum exp_opcode): Add Modula-2 specific opcodes.
1102 * expprint.c: Look up expression opcodes in language-specific

1135 Tue Sep 17 08:37:41 1991 John Gilmore (gnu at cygint.cygnus.com)
1137 Add Andrew Beers' changes for Modula-2 support. His ChangeLog
1138 entries are enclosed herein. Not all of these changes
1139 have been merged into the master GDB sources -- check the
1140 ChangeLog above here for the merge log.
1142 Mon Jun 3 17:05:45 EDT 1991
1144 m2-exp.y Created. Tested outside of GDB for a few days. Proper
1145 operators were added, C specific operators and tokens
1146 removed. yylex() revamped to some extent. Still things
1147 missing from the grammar, such as sets.
1148 Tested for two weeks in GDB v3.5.
1150 Tue Jun 11 17:23:48 EDT 1991
1152 m2-exp.y Added boolean constants TRUE and FALSE to the grammar
1153 so they are built-in. Sort of a hack.
1155 Fri Jun 14 12:53:51 EDT 1991
1157 m2-exp.y Added range checking for numeric constants. Any numeric
1158 constant is assumed to be of builtin type INTEGER unless:
1159 (1) it is octal or hexadecimal, in which case it is a
1160 CARDINAL; (2) it is too big to fit into an INTEGER, in
1161 which case it is a CARDINAL.
1162 eval.c Added simple range checking for +, -, and * on integers.
1163 Doesn't work very well for *, since 6 * 1,000,000,000 =
1164 1,705,032,704, which fails the simple test of result >=
1165 first_operand, no matter in what order the operands are.
1167 Tue Jun 18 14:11:30 EDT 1991
1169 Broke the parser into parts, one containing the C grammar and the other
1170 containing code to be shared by all of the grammars.
1172 The following files no longer exist:
1177 The following files were added:
1179 c-exp.y (The C grammar)
1180 m2-exp.y (The Modula-2 grammar)
1181 parser-code.c (Code that is shared by the above grammar)
1185 Makefile.dist Changed to reflect the above dependencies. NOTE: It is
1186 now necessary to use the Bison compiler compiler, since it
1187 will generate function/variable prefixes other than yy.
1189 Tue Jun 18 16:47:49 EDT 1991
1191 symtab.[ch] Added the external variable working_lang, than holds the
1192 value of the current working language.
1193 Added the ennumerated type language_mode, with the values
1194 language_auto and language_manual, the former meaning that
1195 GDB sets working_lang as needed, and the latter meaning
1196 that the value of working_lang is totally under user
1198 symtab.[ch] Added the Modula-2 pervasive types INTEGER, CARDINAL,
1199 REAL, BOOLEAN and CHAR. Also added the type codes
1200 TYPE_CODE_BOOL and TYPE_CODE_CHAR.
1201 utils.c Added set_language_command and show_language_command to
1202 implement the GDB support commands "set language" and
1204 expression.h A number of identifiers were added to the type exp_opcode
1205 to facilitate Modula-2 builtin functions, integer
1206 division, and array indexing.
1208 Wed Jun 19 13:25:58 EDT 1991
1210 language.h Added the macro STRICT_TYPE, which evaluates to non-zero
1211 if the language specified by working_lang requires the use
1212 of strict typing of expressions. Eventually, even this
1213 will be able to be changed by the user.
1214 Added the macro RANGE_CHECK, which evaluates to non-zero
1215 if the language specified by working_lang requires the
1216 checking of a value against the domain of its type.
1217 Eventually, even this will be able to be changed by the
1219 language.[ch] Predicates involving types (simple_type, ordered_type,
1220 same_type, integral_type, numeric_type, character_type,
1221 boolean_type, float_type) are added. These predicates are
1222 based on the current value of working_lang, and are handy
1225 Wed Jun 19 15:39:34 EDT 1991
1227 eval.c Added the function type_array_rank which computes the rank
1229 valarith.c Added the funtion value_bool, which when given a integer
1230 value.h value (ie. struct value *) as an argument, it returns a
1231 boolean value (ie. struct value *) true if that integer
1232 is non-zero, and a boolean value false otherwise.
1233 valprint.c Added cases for TYPE_CODE_BOOL, so Modula-2 BOOLEAN values
1234 will print out properly.
1236 Wed Jun 19 16:36:34 EDT 1991
1238 valops.c Added the function value_capitalize, which returns it
1239 value.h argument capitalized if its argument is a lowercase
1240 letter, or the argument unchanged if its argument is not a
1242 valarith.c Added the function range_check_p, which returns non-zero
1243 value.h if its value argument is between the integral bounds upper
1245 Added the function range_check_enum_p, which makes sure
1246 that its value argument is a valid member of the domain of
1248 Added the function range_check_range_p, which makes sure
1249 its value argument lies between the upper and lower bounds
1250 of its type argument, which must be a ranged type.
1251 Added the function check_array_index, which range and type
1252 checks an index of an array.
1253 Added the function value_multi_subscript, which computes
1254 array[idx1,idx2...idxN], given a value array and an array
1255 of values representing indicies.
1256 values.c Changed value_from_long to work with TYPE_CODE_CHAR and
1257 unpack_long to work with TYPE_CODE_BOOL and
1260 Wed Jun 19 18:04:08 EDT 1991
1262 symtab.c Stored pervasive types in a structure and make
1263 lookup_pervasive_type() a lookup function that was based
1264 on working_lang. If lookup_pervasive_type() returned
1265 non-zero, then that value was returned (a fix, since
1266 before it simply wouldn't return the pervasive type.)
1267 language.h Added the macro CAST_IS_CONVERSION, which evaluates to
1268 non-zero if the language specified by working_lang means
1269 "conversion" when it says "cast".
1270 valops.c Added the function value_real_cast(), which performs a
1271 value.h *cast*, not a *conversion*, which is what value_cast()
1272 does when it can. In particular,
1273 value_cast(<float_type>,4) = 4.0, while
1274 value_real_cast(<float_type>,4) = some mess.
1275 eval.c Modula-2 builtin functions implemented: ABS, CAP, CHR,
1276 parser-code.c FLOAT, HIGH, MAX, MIN, ODD, ORD, TRUNC, and VAL.
1277 expression.h Added macros MAX_OF_TYPE and MIN_OF_TYPE to work with MAX
1278 and MIN on integral types. *NOTE*: These are currently
1279 hardcoded to work only if there are 8 bits per storage
1281 eval.c Made logical functions call value_bool to return a
1282 properly typed boolean value, based on working_lang.
1284 Thu Jun 20 11:55:27 EDT 1991
1286 valprint.c Types now print out in a Modula-2 fashion. This works for
1287 the cases when the type is printed out step-by-step, that
1288 is, it doesn't work when the name of a structured type
1289 (which includes the keyword "struct", etc.) is simply
1291 FIXME: Perhaps this is bad. Parts of it seem to kludgey,
1292 since type specifications in C and Modula-2 are very
1293 different. The C printing of a type is very recursive,
1294 whereas in Modula-2 it is generally very simple. C has
1295 type prefixes and suffixes, which have no real analogue in
1296 Modula-2. Maybe type_print() should call a language
1297 specific type printer. This is also advantageous if we
1298 compile GDB to exclude some of the languages. We'll just
1299 leave those functions out.
1301 Thu Jun 20 16:57:10 EDT 1991
1303 dbxread.c When reading the complete symbol table in (via
1304 psymtab_to_symtab()), the number and types of function
1305 arguments are added to a function type. define_symbol()
1306 calls add_param_to_type() to accomplish this.
1307 Assumption: when we come across a function definition
1308 (N_FUN symbol with an 'f' or 'F' in the name), its
1309 arguments will appear before another function definition.
1310 When a function is found, a pointer to its type is placed
1311 in the global in_function_type. Changes that
1312 add_param_to_type() makes are to this global.
1313 valprint.c The type of a function now includes (for Modula-2) the
1314 types of its parameters.
1315 eval.c Type checking and a check for the proper number of
1316 arguments is now done for function calls. Not sure of the
1317 impact this has on C++ member function yet.
1319 Thu Jun 20 19:58:48 EDT 1991
1321 valprint.c Rewrote the type printer. Broke it into two language
1322 specific parts, adding the functions type_print_m2() and
1324 An unfortunate consequence is this: if you debugging a C
1325 program in Modula-2 mode (why?), info types does not work
1326 well with regular expressions, since the types are printed
1327 out in Modula-2 terminology, but stored in C terminology.
1328 language.[ch] Added the functions new_type_last(), type_keyword(), and
1329 type_sep() to aid in the printing of typedefs.
1330 symtab.c Made the printing of typedefs as language independent as
1331 possible through calls to new_type_last(), type_keyword(),
1334 Fri Jun 21 11:50:26 EDT 1991
1336 dbxread.c Check all incoming ennumerated types. If it looks like
1337 Modula-2's BOOLEAN type, then change the type_code of the
1338 type to TYPE_CODE_BOOL so we can process it as a boolean
1340 valprint.c Replaced some of the 0x%x with calls to sprintf and
1341 hexformat() in val_print().
1342 language.[ch] Added the function hex_to_string(), which converts its
1343 integral argument to a hexadecimal number (format is
1344 language based) and returns the result as a string.
1346 Mon Jun 24 12:25:07 EDT 1991
1348 valprint.c Some functions call type_print_1() directly, instead of
1349 value.h using type_print(), so they can specify where (column) to
1350 print things. Since type_print() takes care of language
1351 dependence, that needs to be called first. Added a
1352 parameter depth to type_print() (so it is now like
1353 type_print_1). Changed type_print to type_print_at, and
1354 made type_print a macro that passes a depth argument of
1356 symmisc.c Changed all calls to type_print_1 to calls to
1358 Makefile.dist Made it possible to build GDB for a specific set of
1359 depend languages. Do this by passing a definition for the macro
1360 LANGS to make. LANGS should be a string containing a
1361 space-separated list of language names (ie. LANGS="c m2").
1362 The default is to build all languages. Note that grammar
1363 files must follow the naming convention of <lang>-exp.y.
1364 gdb.lang This holds the current value of the LANGS macro. It is
1365 examined every time make is called, and is updated if
1367 eval.c Added #ifdef _LANG_<lang> to these files.
1368 expread.c Still need to add them to dbxread.c and coffread.c.
1376 Mon Jun 24 16:33:11 EDT 1991
1378 language.[ch] Added the functions hexformat_pre() and
1379 hex_to_string_pre(), which take a prefix argument to
1380 include in the format string. Thus, hexformat_pre("08") will
1381 return "0x08x" (if the working language is language_c).
1382 Made hexformat() and hex_to_string() calls to the above
1383 with "" as the prefix argument.
1385 am29k-pinsn.c, arm-pinsn.c, breakpoint.c, convex-tdep.c, exec.c, core.c,
1386 dbxread.c, i386-pinsn.c, i386-stub.c, i386-xdep.c, i960-pinsn.c,
1387 infcmd.c, inflow.c, m68k-pinsn.c, m68k-stub.c, m88k-pinsn.c,
1388 mips-pinsn.c, mips-tdep.c, ns32k-pinsn.c, printcmd.c, pyr-pinsn.c,
1389 pyr-tdep.c, pyr-xdep.c, remote-vx.c, remote.c, solib.c, source.c,
1390 stack.c, sun386-xdep.c, symfile.c, symm-xdep.c, symmisc.c, tahoe-pinsn.c,
1391 valprint.c, vax-pinsn.c
1393 Changed all occurences of 0x%[0-9]*l*x in printf format strings to
1394 calls to hexformat() and hex_to_string(). Format strings without
1395 the leading "0x" were ignored.
1397 depend Updated to take the above into account.
1400 Tue Jun 25 15:27:18 EDT 1991
1402 symtab.h Added the types range_mode_t, range_check_t, type_mode_t,
1403 and type_check_t to keep track of the current state of
1404 range and type checking.
1405 main.c Added the variables range_mode, range_check, type_mode,
1406 and type_check to record the current state of range and
1407 type checking. Added initialization code to main().
1408 language.h Changed the macros STRICT_TYPE and RANGE_CHECK to examine
1409 the above variables.
1412 Tue Jun 25 17:57:08 EDT 1991
1414 dbxread.c process_one_symbol() updates the variable (enum language)
1415 source_lang based on the extension of the filename
1416 contained in the N_SO sybmol that started this symtab.
1417 When end_symtab() is called, the value of source_lang is
1418 put into the language field.
1419 stack.c select_frame() sets working_lang (and possibly type_check
1420 and range_check) to the language field of the symtab
1421 associated with the frame that is selected if working_mode
1422 is language_auto. If working_mode is language_manual, a
1423 warning is printed and working_lang is not set.
1424 language.c Added the function set_type_range(), which sets the value of
1425 type_check and range_check (if their modes call for
1426 automatic setting) based on the current value of
1427 working_lang. A non-zero argument will cause the current
1428 settings to be output.
1431 Wed Jun 26 14:51:40 EDT 1991
1433 eval.c Added range checks on assignment.
1434 m2-exp.y Added the grammar for sets to the language. Currently,
1435 these do not do anything except print an error message.
1437 Wed Jun 26 17:01:04 EDT 1991
1439 m2-exp.y Added the ability for parse_number() to parse negative
1440 numbers. A global flag is set upon encountering a unary
1441 minus. This was done to make, for example, 1 parse as a
1442 CARDINAL, and not as an integer, per Wirth's examples in
1443 Programming in Modula-2 ed.4.
1444 valprint.c Added support for "set radix 2" by then setting
1445 output_format to 't'.
1446 eval.c Implemented range checking on subrange types. Added calls
1447 to range_check_range_p for BINOP_ASSIGN and BINOP_VAL.
1448 Implemented MIN and MAX for ennumerated types. The
1449 minimum value of an ennumerated type is defined by Wirth
1450 as the first identifier, and the maximum as the last.
1451 m2-exp.y Made octal numbers ending with "B" be characters and those
1452 ending with "C" be numbers, per Wirth's book. (p. 34)
1454 Thu Jun 27 14:11:52 EDT 1991
1456 stack.c select_frame() now only sets working_lang, it does not
1457 notify the user. If working_mode is language_manual, then
1458 a warning is issued once.
1459 main.c At the end of each call to execute_command(), working_lang
1460 is checked against the local static (enum language)
1461 current. If they differ and working_mode is
1462 language_auto, the new settings of language, type and
1463 range checking are printed out.
1464 stack.c Modified frame_info() to include the language of the
1465 current frame in the output of "info frame".
1466 language.[ch] Added the function language_str() which returns the name
1467 of the current language.
1469 Fri Jun 28 15:33:14 EDT 1991
1471 m2-exp.y Added the built-in procedures INC, INCL, DEC, and DECL to
1472 the language. INCL and DECL currently cause an error,
1473 since sets are not implemented yet. INC and DEC are
1474 implemented as PREINCREMENT/PREDECREMENT with one
1475 argument, and as ASSIGN_MODIFY with two arguments.
1476 eval.c Added type checking to the above cases.
1477 value.h Added not_lval_constant to the lval_type ennumerated type.
1478 not_lval_constant means that the value is a constant
1479 value; that is 3 or 'a' or TRUE, not as in a constant
1480 identifier. This is used to help coerce numbers such as 3
1481 to either signed or unsigned numbers.
1482 valops.c Added the function value_coerce_constants() which coerces
1483 constant integers as following: if one is a constant and
1484 the other is not, the constant's type is set to the type
1485 of the other argument. If both are constants and one is
1486 signed, the other is converted to a signed constant.
1488 Sat Jun 29 17:26:29 EDT 1991
1490 valarith.c Added a better range checker. It now checks range
1491 (successfully) on integral operations [+-] (signed and
1492 unsigned) for any C sized type. Still does not work well
1493 for multiplication.)
1494 int_in_size() returns an integer that is coerced to fit into
1495 specified number of bytes.
1497 Mon Jul 1 13:04:14 EDT 1991
1499 language.[ch] Added the function binop_result_type(), which returns the
1500 builtin (struct type *) type that would be the result of a
1501 binop on the two values V1 and V2.
1503 Wed Jul 3 19:22:53 EDT 1991
1505 source.c Extended source_info() to include the source language in
1506 the output from "info source".
1508 Fri Jul 5 13:48:52 EDT 1991
1510 utils.c Moved the support functions for the GDB set/show commands
1511 dealing with language into language.c.
1512 language.c Added the function language_info(), which displays info
1513 about the current working language, type and range check
1514 settings. Called via the GDB command "info language".
1515 Added an initialization routine _initialize_language(),
1516 that sets defaults for the language, type and range
1517 variables and sets up the new GDB commands.
1518 main.c Language setup moved to language.c.
1521 Mon Jul 8 10:10:22 EDT 1991
1523 valarith.c Debugged the range checker for arithmetic. Still does not
1524 work for multiplication very well.
1526 Mon Jul 8 12:40:37 EDT 1991
1528 language.[ch] Added the function value_true() which returns non-zero if
1529 its argument represents a boolean true value.
1530 breakpoint.c Changed breakpoint_cond_eval() to call value_true() to
1531 check the truth of an expression.
1533 Thu Jul 11 12:51:34 EDT 1991
1535 language.[ch] Added the predicate structured_type(), which returns
1536 non-zero if the argument is a structured type.
1537 Added the predicate pointer_type(), which returns non-zero
1538 if the argument is a pointer type.
1539 eval.c Added the ability to do addition and substraction on
1540 pointers and integers. This case simply bypasses the
1543 Thu Jul 11 14:41:42 EDT 1991
1546 Added the symbol N_DEFD (0x4a) which is a definition
1547 module dependency that is used by the GNU Modula-2
1548 compiler and the linker. It is not important to GDB,
1549 except that [dbx|coff|mips]read.c should ignore these
1552 Fri Jul 12 16:07:00 EDT 1991
1554 valprint.c Changed the TYPE_LENGTH(type) >= 0 to TYPE_LENGTH(type) >
1555 0 in val_print(). Also added statements to the else part
1556 to coerce type (argument to val_print) to a pointer type
1557 if it is an "array of unspecified length".
1558 valops.c Added the function value_m2_string(), which returns a
1559 (value) value which is a constant string, whose type is
1560 (ARRAY [0..n] OF CHAR). The length field of the type
1561 structure is set to zero, so it will be interpreted as an
1562 "array of unspecified length".
1563 stack.c Moved the language/frame mismatch check to
1564 main.c:execute_command().
1565 main.c The working language is recorded each time
1566 execute_command() is executed. If working lang has
1567 changed during its execution, then the new
1568 language/type/range info is printed out for the user. If
1569 the working language does not match the language of the
1570 frame, a warning is issued.
1572 Sat Jul 13 16:16:39 EDT 1991
1574 eval.c Moved all the type-checking stuff for operators to
1575 language.[ch] language.c. This is so we can keep language-specific
1576 stuff (like for what type operators are defined) in
1578 language.[ch] Added the function binop_type_check(), which checks to see
1579 if its two (value) arguments are type-compatible with its
1580 opcode argument. The opcode should represent an operation
1581 involving an operator. Also added the macro function
1582 unop_type_check, which calls binop_type_check with a
1583 NULL second argument.
1584 expprint.c Added Modula-2 operators to the op_print_tab, so info
1585 expression.h break works correctly. Also added "op_string", which
1586 returns the string corresponding to the (enum exp_opcode)
1587 opcode that is its argument.
1590 Sat Jul 13 18:26:18 EDT 1991
1592 coffread.c Added code to record the type of function arguments with
1593 each paricular function. Code is very similar to that
1595 dbxread.c Moved add_param_to_type() to symtab.c
1596 symtab.[ch] Added function add_param_to_type() from dbxread.c
1598 *** NOTE: The above additions have not been tested.
1600 Mon Jul 15 12:50:47 EDT 1991
1602 langauge.[ch] Added the functions type_error and range_error, which work
1603 like error() except if the type/range mode is set to
1604 *_mode_warn, then they do not do a return_to_top_level(),
1605 but merely print a warning.
1606 Also changed [set|show]_[type|range]_command() to support
1607 the new "warn" feature.
1609 Thu Jul 18 17:50:54 EDT 1991
1611 mipsread.c Added code to record the type of function arguments with
1612 each particular function. Code is very similar to that
1615 *** NOTE: The above additions have not been tested.
1617 Fri Jul 19 11:19:10 EDT 1991
1619 defs.h Added macros MAX_OF_SIZE, MIN_OF_SIZE, UMAX_OF_SIZE, and
1620 UMIN_OF_SIZE, which when given a size of a numeric type,
1621 return the maximum and minimum value it can hold. UMAX...
1622 and UMIN... return the result for unsigned types.
1623 symtab.h Added the macros MAX_OF_TYPE and MIN_OF_TYPE to operate on
1624 struct types. They call above macros.
1625 dbxread.c Renamed the MAX and MIN_OF_TYPE macros to ..._OF_CTYPE to
1626 avoid a name conlict with the above.
1627 c-exp.y Added range checking on numeric constants in
1628 parse_number() for completeness.
1629 valarith.c Made binop_user_defined_p() and unop_user_defined_p()
1630 return 0 if working_lang is not language_c.
1632 Thu Aug 8 14:17:22 EDT 1991
1636 breakpoint.c Documentation strings of some commands changed to
1637 eliminate the references to the C language where
1640 Tue Aug 13 15:48:03 EDT 1991
1642 m2-exp.y Added qualified identifiers to the grammar. The semantics
1643 are slightly different from those of the GDB operator ::
1645 m2-exp.y Added a rule to each grammar of the form: start ::= exp |
1646 type_exp, where type_exp is any valid type expression.
1648 eval.c Added the opcode OP_TYPE, and an error case in eval.c.
1649 printcmd.c Modified ptype_command() so it actually parses the input
1650 (necessary for type expressions with scope qualifiers).
1651 Added the function ptype_eval() which expects an
1652 expression composed of one OP_TYPE element.
1653 *.[ch] Replaced all occurences of parse_c_expression with
1655 *.[ch] Replaced all occurences of parse_c_1 with parse_exp_1
1657 [End of ChangeLog entries from Andrew Beers for Modula-2 support.]
1659 Mon Sep 16 17:19:46 1991 John Gilmore (gnu at cygnus.com)
1661 Small fixes from Peter Schauer:
1663 * infrun.c (child_attach): Lint.
1664 * solib.c (find_solib): Handle shared libs version 2.
1666 Small fixes from David Wood:
1668 * xm-ultra3.h (SYS_SIGLIST_MISSING): Typo.
1672 * remote-vx.c: Move <stdio.h> to top, for FILE. Fix from
1673 John S <basrai%kanga.dnet@c3po.sm-alc.af.mil>.
1675 * utils.c (wrap_here): Avoid wrap action of fputs_filtered if
1676 chars_per_line is at maximum (user typed `set width 0'). Fix
1677 from Andreas Schwab <schwab@ls5.informatik.uni-dortmund.de>.
1679 Tue Sep 17 17:31:04 1991 Stu Grossman (grossman at cygnus.com)
1681 * coredep.c: include ptrace.h where necessary.
1682 * mipsread.c(parse_lines): fix unsigned char problem that was
1683 messing up line numbers on SGI's and possibly other MIPS based
1685 * infrun.c (child_create_inferior): use better test to check
1686 return val from setpgrp().
1687 * tm-irix3.h, xm-irix3.h, tconfig/irix3, xconfig/irix3: add these
1688 for sgi/irix support.
1690 Wed Sep 18 04:33:31 1991 Per Bothner (bothner at cygnus.com)
1692 * mipsread.c (parse_symbol): Put non-static procedures
1693 in the global block.
1695 Fri Sep 13 00:14:52 1991 John Gilmore (gnu at cygnus.com)
1697 Patch together `text_start' and `text_end' for 29K port.
1699 * exec.c (exec_command): If NEED_TEXT_START_END, define the
1700 variables and set them based on the exec file.
1701 * am29k-tdep.c: declare text_start.
1702 * valops.c (call_function_by_hand): declare text_end.
1704 * inferior.h: Eliminate CANNOT_EXECUTE_STACK in favor of
1705 defining CALL_DUMMY_LOCATION as BEFORE_TEXT_END. This is
1706 because machines that do this will also have to know to
1707 set NEED_TEXT_START_END. Besides, it was a redundant way to
1709 * tm-29k.h, tm-convex.h, tm-np1.h: Eliminate
1710 CANNOT_EXECUTE_STACK, define CALL_DUMMY_LOCATION and
1711 NEED_TEXT_START_END.
1713 Thu Sep 12 00:22:24 1991 John Gilmore (gnu at cygint.cygnus.com)
1715 AMD 29000 changes from David Wood <wood@david.ultra.nyu.edu>:
1717 * Makefile.in (CLIBS): Put XM_CLIBS and TM_CLIBS at end.
1718 Pass MUNCH_DEFINE to munch whenever we run it.
1719 * am29k-pinsn.c (print_insn): Handle NOP specially. Avoid %#x
1720 format string; use 0x%x instead.
1721 * am29k-tdep.c: Use DUMMY_SAVE_GREGS and RETURN_REGNUM.
1722 * ultra-xdep.c, xm-ultra.h: New files for Ultracomputer host system.
1723 * xm-rtbsd.h: New host support for RT/PC running BSD Unix.
1724 * inflow.c: Handle `short' process group IDs.
1725 * infptrace.c (fetch_register): Support CANNOT_FETCH_REGISTER,
1726 and check for ptrace errors.
1727 * coffread.c (SDB_REG_TO_REGNUM): Define if not already.
1728 (coff_symfile_init): Initialize text_bfd_scnum.
1729 (read_coff_symtab): Use it to find the text [and absolute?] sections.
1730 * ../config.sub: Add vendor nyu and os "sym[1-9]*".
1731 * configure.in: Add hosts rtpc-*-* and a29k-*-*.
1732 Merge target arm case with other "easy" cases. Add target
1733 cases a29k-*-none (rehack of am29k), a29k-*-kern (remote to
1734 Ultracomputer kernel), and a29k-*-sym1 (ultracomputer OS's user
1736 * minimon.h, remote-adapt.c, remote-mm.c: Add.
1737 * munch: Cope with RT/PC putting fns in data segment.
1738 Restore ability to override `nm' by specifying MUNCH_NM.
1739 * xconfig/rtbsd, xconfig/ultra3: New host systems.
1740 * tconfig/a29k: Rename from tconfig/am29k. Add remote-mm
1741 and remote-adapt. Remove encapsulated coff #define's (the
1742 support should go in BFD, and gdb shouldn't know or care).
1743 * tconfig/a29k-kern: Same, but for remote kernel debugging.
1744 * tconfig/ultra3: For debugging user processes on Ultra3/Sym1.
1745 * tm-29k.h: Update BADMAG (though it should go away).
1746 Allow the register definitions to be overridden in another
1747 tm-file. Fix SR_REGNUM. Add a mess of _REGNUM's. Separate
1748 RETURN_REGNUM from GR96_REGNUM and DUMMY_SAVE_GREGS from
1749 DUMMY_SAVE_GR96, for handling kernel calling conventions
1750 that use GR64+ rather than GR96+.
1751 * tm-ultra3.h: New file, for use on Ultra3 Unix as well as for
1752 remote debugging of Ultra3 kernel. Includes tm-29k.h and
1753 overrides various things.
1755 * remote-mm.c (mm_attach, mm_wait): Handle attach like
1756 child_attach does, making a clean stop in the newly attached
1758 * remote-eb.c: Lint.
1760 * coffread.c: Make coffread independent of any particular
1761 variant of COFF. Avoid #include-ing any particular one except
1762 internalcoff.h. BFD now passes key values for symbol reading
1763 as part of its coff_data structure (LINESZ, SYMESZ, AUXESZ,
1764 and the symbol masks and shifts); use them.
1765 Remove obsolete end_of_text_addr.
1767 * exec.c: Remove unused include files.
1769 Wed Sep 11 19:38:44 1991 John Gilmore (gnu at cygint.cygnus.com)
1771 * Makefile.in (documentation targets): Pass $(M4).
1772 Bugfix from eggert@twinsun.com (Paul Eggert).
1774 * stack.c (down_silently_command): Check for stack existence.
1776 Tue Sep 10 23:08:29 1991 John Gilmore (gnu at cygint.cygnus.com)
1778 * Makefile.in (VERSION): Update to 4.0.3.
1780 Tue Sep 10 09:19:29 1991 John Gilmore (gnu at cygint.cygnus.com)
1782 * core.c (core_file_command): Print frame at coredump with
1783 its level number, by calling print_stack_frame.
1784 * frame.h: Add selected_frame_level, print_stack_frame.
1785 * frame.h, stack.c: Remove print_sel_frame, print_selected_frame.
1786 * convex-tdep.c, convex-xdep.c, infcmd.c, inflow.c, infrun.c:
1787 Change print_sel_frame and print_selected_frame callers to
1790 * dbxread.c (read_ofile_symtab): Avoid empty else clause.
1791 * symfile.c (free_named_symtabs): Ditto.
1792 * main.c (main): wrap_here needs an arg.
1793 * solib.c (find_solib): Avoid memory access if _DYNAMIC is zero.
1794 (solib_add): Avoid noise.
1795 (solib_create_inferior_hook): Lint.
1796 (sharedlibrary_command): Move dont_repeat to here.
1797 * utils.c (error): Call wrap_here to force buffered output.
1799 Small patches from Peter Schauer:
1801 * coffread.c (start_symtab): Free any existing line_vector before
1803 (read_coff_symtab): Ditto for type_vector.
1805 * source.c (lines_to_list): New variable, replacing function.
1806 (all uses): Use as variable.
1807 (_initialize_source): Add 'set listsize' and 'show listsize'.
1808 * utils.c (lines_to_list): Remove function.
1809 * stack.c (print_frame_info): Use as variable.
1810 * defs.h (lines_to_list): Remove declaration.
1812 Mon Sep 9 13:45:57 1991 John Gilmore (gnu at cygint.cygnus.com)
1814 * breakpoint.c (insert_breakpoints): Restore warning about
1815 the program might be running in another process, but only for
1816 systems with this brain death (#ifdef ONE_PROCESS_WRITETEXT).
1817 * xm-hp300bsd.h, xm-mips.h, xm-vax.h: Define it.
1819 * utils.c (error): if error_pre_print is set, print the string
1821 * main.c (main, print_gnu_advertisement, print_gdb_version):
1822 Reformat legalese so it always prints, but acts as an "I'm here"
1823 message while symbols are being read. If any errors occur,
1824 print a few newlines to set off the message and start it at the
1825 left margin. Remove mention of "help" command, and don't yak
1826 about symbol reading.
1827 (catch_errors): Error string is now printed first in case of
1829 * command.c (undef_cmd_error, lookup_cmd): On undefined command,
1830 suggest the "help" command.
1832 * Makefile.in (VERSION): Set to 4.0.2.
1834 Thu Sep 5 23:49:48 1991 John Gilmore (gnu at cygint.cygnus.com)
1836 * .gdbinit: Remove useless "rr" command. Set complaints
1837 to 1 for people debugging gdb.
1839 * breakpoint.c, remote-vx.c: Reword strings printed by
1840 catch_errors callers.
1842 Wed Sep 4 11:07:50 1991 John Gilmore (gnu at cygint.cygnus.com)
1844 * WHATS.NEW: "history write -> history save". Doc "write on/off".
1845 (Fix from kenc@viewlogic.com.)
1847 Fix some infrastructure to be able to cope with host and target
1848 machines with different sized basic types (ints, ptrs, etc).
1849 (Idea from pierre@la.tce.com (Pierre Willard).)
1851 * values.c (value_from_longest): Rename from value_from_long.
1852 Handle pointer types as well as integers, so that targets with
1853 different pointer sizes from the host can be accomodated.
1854 * breakpoint.c, convex-tdep.c, eval.c, expprint.c, printcmd.c,
1855 valarith.c, valops.c, valprint.c, value.h, values.c: Rename
1856 uses of value_from_long to value_from_longest.
1857 * eval.c, findvar.c, printcmd.c, valarith.c, valops.c: Pass
1858 the correct pointer type to value_from_long{est}.
1860 * doc/gdb.texinfo ($_, $__): Describe types of these variables.
1862 * remote-vx.c: Remove obsolete code for calling functions via
1863 vxworks kludge interface (it referenced value_from_long).
1865 * valops.c (value_string): Find malloc with lookup_misc_func, not
1868 Tue Sep 3 18:37:46 1991 John Gilmore (gnu at cygint.cygnus.com)
1870 Make writing to files work properly. (Fixes to BFD are also needed.)
1872 * core.c (core_open): Open file ourselves, read or r/w, depending on
1873 write_files. Use bfd_fdopenr.
1874 * gdbcore.h (write_files): New variable.
1875 * exec.c (write_files): Define variable, add set&show for it.
1876 (exec_file_command): Use write_files to open for read or r/write.
1878 Make shared library reading happen automatically. These changes
1879 are mostly from Peter Schauer <pes@regent.e-technik.tu-muenchen.de>.
1881 * inferior.h (stop_soon_quietly): Add to exported variables.
1882 * infrun.c (child_create_inferior): call solib hook, if defined.
1883 (child_attach): call solib hook, if defined.
1884 * solib.c: Include inferior.h. Add from_tty to so_list as kludge.
1885 (find_solib): Use lookup_misc_func rather than hand-rolled.
1886 (symbol_add_stub): New stub for catch_errors.
1887 (solib_add): Avoid output if !from_tty. Catch errors rather
1888 than just calling symbol_file_add and bombing.
1889 (solib_create_inferior_hook): Interface with the target process
1890 to let it read and alloc shared libs, then figure out what it did.
1892 * core.c (validate_files): Fix typo, soften warning.
1893 (Fix from Hiroto Kagotani <kagotani@cs.titech.ac.jp>.)
1895 * utils.c (fputs_demangled): Avoid duplicate printing if
1896 demangling is off. (Fix from J.T. Conklin <jtc@cayenne.com>.)
1898 * infrun.c (proceed): Cast -1 to (CORE_ADDR) before comparing.
1899 (Fix from pierre@la.tce.com (Pierre Willard).)
1901 * main.c (catch_errors): Change argument to a char * from an int,
1902 since a char * can point to a struct full of glop, but an int
1903 is not guaranteed to be able to hold a pointer.
1904 * breakpoint.c (breakpoint_cond_eval, bpstat_stop_status,
1905 breakpoint_re_set_one, breakpoint_re_set): Adapt.
1906 * core.c (core_open, solib_add_stub): Adapt.
1907 * remote-vx.c (symbol_stub, add_symbol_stub, callers): Adapt.
1909 Wed Aug 28 18:18:05 1991 John Gilmore (gnu at cygint.cygnus.com)
1911 * Makefile.in: Update VERSION to 4.0.1. Evade GNU Make bug
1912 by adding .NOEXPORT target.
1914 Fri Aug 23 17:14:25 1991 John Gilmore (gnu at cygint.cygnus.com)
1918 * Makefile.in (VERSION): Roll to 4.0.
1919 (gdb.tar.Z): Make refcard.ps as well, for shipment.
1921 Fri Aug 23 14:07:09 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1923 * doc/gdb.texinfo: minor rewordings, crossref to ptype from print,
1926 * doc/Makefile, Makefile.in: generate "gdb-all.texi" rather than
1929 * doc/rdl-apps.texi: renamed from rdl-apps.texinfo
1931 * Makefile.in, doc/Makefile, doc/.Sanitize, doc/gdb.texinfo:
1932 reflect above name change
1934 * WHATS.NEW: correct pointer to refcard.
1936 * doc/gdb.texinfo: update New Features, Installing
1938 * doc/gdbint.texinfo: add short description of configure +template
1940 Fri Aug 23 11:46:08 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1942 * doc/gdb.texinfo: update, fix bugs in "Installing" appendix
1944 Fri Aug 23 01:02:00 1991 John Gilmore (gnu at cygint.cygnus.com)
1946 * Makefile.in: Add config.sub, make doc/rdl-apps.texinfo for
1947 tar file, add dependencies for referenced doc files.
1949 Thu Aug 22 22:17:06 1991 Stu Grossman (grossman at cygint.cygnus.com)
1951 * coffread.c, symfile.c, stack.c: saberized.
1953 Thu Aug 22 16:20:27 1991 Roland H. Pesch (pesch at cygint.cygnus.com)

1965 Thu Aug 22 14:05:47 1991 Stu Grossman (grossman at cygint.cygnus.com)
1967 * expread.y, coffread.c, dbxread.c, target.c, mem-break.c,
1968 cplus-dem.c, values.c, valprint.c, symfile.c, remote.c,
1969 breakpoint.c, main.c: lint.
1971 Thu Aug 22 02:02:26 1991 John Gilmore (gnu at cygint.cygnus.com)
1973 Install new configuration scheme for GDB and friends.
1975 * config.sub: Translate ordinary names to three-part names.
1976 * configure: Use three-part names internally.
1977 * configure.in: Translate three-part names to filenames.
1979 * README, WHATS.NEW: Update for gdb-4.0.
1980 * Makefile.in: Roll VERSION to 3.99.
1982 Wed Aug 21 18:21:09 1991 John Gilmore (gnu at cygint.cygnus.com)
1984 * infptrace.c (KERNEL_U_ADDR_BSD): Include a.out.gnu.h.
1985 * i960-tdep.c, m68k-tdep.c, sparc-tdep.c, tm-i960.h,
1986 tm-m68k.h, remote-nindy.c: Change ext_format_XXX structs
1987 to single structures rather than arrays; when passing
1988 their address, use &. This avoids trouble with bdead compilers.
1989 * mcheck.c: Don't include <stdlib.h>; just declare "void abort();"
1990 instead. This avoids portability headaches.
1991 * mips-tdep.c (mips_do_registers_info): Only print FP regs if
1993 * source.c (open_source_file): Avoid ANSI const bdeath by
1994 skipping declaration and then casting result value.
1995 * tm-hp300bsd.h: Clarify comment.
1996 * utils.c (strstr): Result is const char *; ANSI bdeath.
1997 * xm-hp300bsd.h: Define HOST_BYTE_ORDER. Redefine INT_MIN,
1998 since system include file defines it differently from "defs.h",
1999 though the two are equivalent for our purposes.
2000 * tconfig/hp300bsd: Add m68k-tdep.o.
2002 Tue Aug 20 16:01:11 1991 John Gilmore (gnu at cygint.cygnus.com)
2004 * tconfig/sun*4: Remove warnings about system assembler.
2006 Mon Aug 19 13:44:46 1991 John Gilmore (gnu at cygint.cygnus.com)
2008 * mcheck.c: Avoid warning about undeclared abort fn.
2009 * tm-sparc.h (PC_ADJUST): Avoid calling error() from this;
2010 it causes recursive calls to error() when used in cleanups.
2011 To do so requires that we make it a function, so we do.
2012 * sparc-tdep.c (sparc_pc_adjust): New implem of PC_ADJUST.
2013 * utils.c (do_cleanups): Remove the current cleanup from the
2014 chain *before* calling it, in case error() is called from it.
2015 The result won't be pretty, but won't be an infinite loop either.
2017 Mon Aug 19 00:41:04 1991 Michael Tiemann (tiemann at cygint.cygnus.com)
2019 * dbxread.c (read_struct_type): Grok anon structs for C++.
2020 (vb_name, vptr_name): Null terminate these strings.
2022 Fri Aug 16 08:31:03 1991 John Gilmore (gnu at cygint.cygnus.com)
2024 Minor bug fixes from BSD Net2 gdb:
2026 * blockframe.c (get_prev_frame_info): If FRAME_CHAIN_COMBINE
2027 returns 0, there is no previous frame.
2028 * breakpoint.c (commands_command): If !from_tty, don't call
2029 input_from_terminal_p().
2030 * dbxread.c (record_misc_function): Speed up slightly.
2031 (compare_psymbols): Ditto.
2032 * infcmd.c (do_registers_info): Take a second argument to
2033 determine whether to print float registers. "info registers"
2034 does not do so anymore. "info all-registers" does, now.
2035 * mips-tdep.c, pyr-tdep.c (xxx_do_registers_info): Take second
2037 * tm-mips.h, tm-pyr.h (DO_REGISTERS_INFO): Pass second arg.
2038 * inflow.c (initialize_inflow): Set tflags_ours correctly.
2042 * breakpoint.c (bpstat_do_actions): Use a cleanup to restore
2043 executing_breakpoint_commands if we are interrupted by error.
2044 * coffread.c (init_lineno): Avoid problem with zero-sized linetab
2045 versus malloc/free. From: john@labtam.labtam.oz.au (John Carey).
2046 * core.c (solib_add_stub, core_open): Call SOLIB_ADD inside a
2047 catch_errors() so we can setup the frame regardless of whether
2048 the shared libs work.
2049 * ieee-float.c (double_to_ieee_extended): Get exponent from
2050 right place in little-endian systems. From John Carey.
2052 Thu Aug 15 18:43:57 1991 John Gilmore (gnu at cygint.cygnus.com)
2054 * main.c: Remove unused terminating_signals and catch_termination().
2055 (long_options): Terminate with a zero element.
2056 [Bugfix from Atsuo Kawaguchi <atsuo@hark86.harl.hitachi.co.jp>.]
2057 (gdb_readline): Make call-compatible with readline.
2058 (init_signals): Improve comments re vfork vs. signal.
2060 * utils.c (prompt_for_continue): Use new gdb_readline().
2061 If we prompt for continuation, we don't let CR repeat the previous
2062 command, once we get back to a prompt. It's too easy to keep
2063 hitting CR, expecting "--more--" prompts, and have some long
2064 command start repeating on you.
2066 Tue Aug 13 16:17:56 1991 John Gilmore (gnu at cygint.cygnus.com)
2068 * blockframe.c (frameless_look_for_prologue): Speed up by
2069 calling SKIP_PROLOGUE_FRAMELESS_P if it's defined.
2070 * tm-sparc.h (SKIP_PROLOGUE, SKIP_PROLOGUE_FRAMELESS_P):
2071 Define two variants, one faster.
2072 * sparc-tdep.c (sparc_frame_chain): Use target_read_memory
2073 and return zero, rather than giving an error.
2074 (setup_arbitrary_frame): Initialize the PC in the new frame.
2075 (skip_prologue): Add a second arg saying whether we're just
2076 checking for a frameless function or not.
2078 * core.c (core_open, core_close, core_xfer_memory): Move
2079 section table pointers and bfd* into the target_ops.
2080 (core_open): Allow errors in shared lib reading, etc.
2081 (core_files_info): Describe shared library sections.
2083 * exec.c (exec_open, exec_close, exec_xfer_memory, xfer_memory,
2084 exec_files_info, set_section_command): Move section table
2085 pointers and bfd* into the target_ops.
2086 (add_to_section_table): Add BFD to section table.
2088 * target.c (target_xfer_memory, target_info): Pass target to
2089 xfer_memory and target_info functions.
2092 * gdbcore.h: Move struct section_table.
2093 * target.h: New home of struct section_table.
2095 * solib.c (solib_add): New argument is the target_ops whose
2096 section list is to be added to, if any. Reallocate the
2097 sections in that target to add any that come from shared libs.
2098 (throughout) so_sections renamed to sections.
2099 (solib_xfer_memory): Deleted.
2100 * tm-sunos.h (SOLIB_ADD): Add target argument.
2101 (SOLIB_XFER_MEMORY): Delete.
2103 * core.c, exec.c, inftarg.c, remote-eb.c, remote-nindy.c,
2104 remote-vx.c, remote.c, target.c, target.h: Remove add_syms vector
2105 from target_ops. It's the same on all targets. Add two section
2106 pointers to target_ops.
2108 * stack.c (find_relative_frame): Dump ancient algorithm for
2109 "down", just use handy "next" pointers.
2110 (frame_command): Don't error if there is no stack; let user
2113 * inflow.c (new_tty_prefork, new_tty): New prefork routine
2114 modifies static state in the parent process; new_tty itself
2115 runs in the child and modifies the child's file descriptors
2116 to match the saved static state.
2117 * infrun.c (child_create_inferior): Call new_tty_prefork,
2120 * infptrace.c (child_xfer_memory): Add ignored target arg.
2121 * remote-eb.c (eb_xfer_inferior_memory): ''
2122 * remote-nindy.c (nindy_xfer_inferior_memory): ''
2123 * remote-vx.c (vx_xfer_memory): ''
2124 * remote.c (remote_xfer_memory): ''. Rename from
2125 remote_xfer_inferior_memory.
2127 * main.c (main): Only try to attach "corefile" argument if
2128 it starts with a digit.
2130 * symfile.c (symbol_reloading): New "set/show" variable.
2131 (symbol_file_add): Shorten message about symbol reading.
2132 (add_symbol_file_command): Merge with add_syms_addr_command,
2133 since this should work on all targets now.
2134 (stop_whining): Default to zero, to shut up complaints
2135 about bad symbol tables on many systems.
2136 (free_named_symtabs): Just exit unless symbol_reloading.
2138 * xm-sun3os4.h, xm-sun4os4.h: Define BROKEN_LARGE_ALLOCA,
2139 and add comment explaining shared library screw.
2141 * source.c: #if defined => #ifdef.
2143 Thu Aug 8 12:23:19 1991 John Gilmore (gnu at cygint.cygnus.com)
2145 * doc/gdbint.texinfo: Improve doc on porting to new OS's.
2147 Tue Aug 6 17:16:15 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
2149 * doc/rdl-apps.texinfo: provide default readline-appendix finder
2150 (doc/Makefile knows how to make one for local config)
2152 * Makefile.in: use doc/Makefile for doc targets
2154 * doc/Makefile: GDB documentation now has its own Makefile
2155 doc/refcard.tex: renamed from "gdbrc.tex"
2156 doc/.Sanitize: add Makefile; recognize renamed refcard.tex
2157 doc/gdbint.texinfo: add markup in "Cleanups" chapter
2160 Fri Aug 2 00:13:06 1991 John Gilmore (gnu at cygint.cygnus.com)
2162 * values.c (baseclass_addr): When reading target memory, use the
2163 length of the basetype, not the upper type. We've only malloc'd
2164 enough space for the basetype, leading to errors in free().
2166 * expprint.c (print_subexp): Print UNOP_MEMVAL of an OP_LONG that
2167 ends up as a function specially, since we know the actual type of
2168 the pointed-to address. This (somewhat) fixes display of
2169 expressions that include misc_function_vector names. Try `cond 1
2170 !strcmp("a","b")' then `i b'.
2172 * infrun.c: Move DO_DEFERRED_STORES from proceed() to resume().
2173 The child can be proceeded from inside wait_for_inferior in
2174 evaluating breakpoint conditions, and DO_DEFERRED_STORES was
2175 getting skipped in that case.
2177 * expprint.c (print_subexp): Use filtered output, since the
2178 subroutines we call use it, otherwise the output is horribly
2179 mangled, since output of wrappable stuff comes out late.
2181 * Makefile.in: Bump VERSION to 3.98.1
2183 * infrun.c (child_create_process): Use execlp to find the
2184 shell to exec our target program. This requires some fiddling
2185 with `environ' since there is no execlpe().
2187 Thu Aug 1 15:35:17 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
2189 * Makefile.in, doc/gdbrc.tex, doc/rc-* (new files):
2190 Minor rearrangement of refcard permits two new make targets--
2191 gdbrc.dvi DVI output for refcard, using CM fonts
2192 gdbrc.ps PostScript refcard, using PS fonts
2194 Wed Jul 31 16:46:21 1991 John Gilmore (gnu at cygint.cygnus.com)
2198 * TODO, Projects, WHATS.NEW, README: Update for gdb-3.98.
2199 * Makefile.in (gdb-all.texinfo): Avoid touching file if M4 dies.
2201 Wed Jul 31 16:35:58 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
2203 * doc/gdb.texinfo: last changes for release.
2204 Minor typo and formatting fixes; incorporated most fixes remaining from
2205 filed mail commenting on earlier drafts.
2207 Added warnings: pipes don't work in run command;
2208 conditions are converse of assertions;
2209 step over fn without debug info goes to next fn;
2210 vars may have "wrong" values near fn entrance, exit
2212 Added example from Kingston on printing repeated nonadjacent values
2214 Added explicit mention that in Emacs gdb mode C-c and C-z are like
2215 shell mode for signals
2217 Renamed "Stepping and Continuing" to "Continuing and Stepping" so it
2218 doesn't sound so much like its parent "Stopping and Continuing"; also
2219 moved entries on continue to top of section, so they don't get lost.
2221 Improved installation directions in appendix, added manual formatting
2224 Tue Jul 30 17:26:39 1991 John Gilmore (gnu at cygint.cygnus.com)
2226 * configure.in: Remove xm.h and tm.h even if we aren't linking
2227 new ones, so "./configure sun4; ./configure none" does the right
2228 thing. Assume that alldeps.mak and depend are already built in
2229 srcdir, and avoid running "make" (particularly "make depend",
2230 which involves "gcc") from inside configure. Build Makefile
2231 directly rather than building Makefile.conf first.
2232 * configure: Regenerate with above changes.
2233 * Makefile.in: Use $(BISON) to find bison. Roll VERSION
2234 to 3.98. Revise gdb.tar.Z procedure to produce a file
2235 called gdb-$(VERSION).tar.Z but which unpacks into a
2236 directory called "gdb". Move non-source files out of
2237 $(SFILES_SUBDIR). Pretty up alldeps.mak with comments.
2238 (depend): Don't try to do "gcc expread.y".
2239 (expread.o): Update dependencies by hand.
2241 Mon Jul 29 15:21:09 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
2244 Fixed a variety of small typos that prevented info from formatting
2245 cleanly; altered too-long heading for GPL Appendix, as discussed
2246 w/RMS; Changed date on cover to July 91.
2248 Fri Jul 26 13:20:02 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
2251 (1) Applied some fixes due to comments from Larry Breed (easier ones
2252 through chapsec 5.2)
2253 (2) Eliminated use of @footnote---had my doubts about it anyways, and
2254 it's broken in latest texinfo
2255 (3) Introduced *some* use of [] for optional arguments, where
2256 explanation is not simpler by listing cmd w arg and cmd w/out arg
2257 separately. Still not using @deffn.
2258 (4) Dropped in GPL-2. NOTE: one of GPL-2 or texinfo is broken; a
2259 couple of headings are too long. Need patches to texinfo or revision
2262 * Partial update to README (which still needs work for this
2263 release!): (1) use of configure corrected for new script,
2264 (2) "make gdb.dvi" and "make gdb.info" mentioned.
2266 Wed Jul 24 06:44:02 1991 John Gilmore (gnu at cygint.cygnus.com)
2268 * symtab.c (lookup_symbol): Don't complain right off about
2269 no debug symbols; use the misc function vector first.
2270 (list_symbols): Use misc function vector to find symbols
2271 that don't have debug info, and print them.
2272 (find_pc_symtab): Temporarily avoid fatal() when psymtab
2273 PC range doesn't match symtab PC range, as it does on the
2274 MIPS because our symtab reading isn't perfect.
2276 * dbxread.c (dbx_symfile_read): Make warning about
2277 "no debug symbols" slightly nicer.
2279 * source.c (select_source_symtab): If "main" symbol exists,
2280 but decode_line_spec can't find line info, don't just return
2281 a zero; try other source symtabs or give an error.
2283 * mipsread.c (parse_partial_symbols): Sort the psymtabs by
2284 their low addresses first, then rip through fixing high addrs.
2286 * ns32k-opcode.h (sfsr): Bugfix from Rune Nerg}rd,
2287 <runene@ifi.uio.no>.
2288 (NS32K_SVC_IMMED_OPERANDS): Reverse the #ifndef.
2290 Tue Jul 23 18:52:43 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
2292 * Minor, mostly mechanical, cleanup of doc subdir for clean
2293 makeinfo'ing and TeXing; also ensured gdb-all.texinfo (post-m4)
2294 and gdb.info (post- texinfo2 makeinfo) generated for distribution.
2296 Sun Jul 21 03:54:52 1991 John Gilmore (gnu at cygint.cygnus.com)
2298 Mostly MIPS and general symbol-reading fixups.
2300 * doc/gdbint.texinfo: Add documentation on symbol-reading
2303 * mipsread.c: Remove kludges around #include "ecoff.h".
2304 Remove redefinitions of a_magic, etc, no longer used.
2305 (parse_symbol, ): Convert "Internal:" printfs to complain()ts.
2306 Fix global overview comments to match symfile.c protocol.
2307 (mipscoff_new_init): Eliminate cur_hdr if we have one.
2308 (mipscoff_symfile_read): Eliminate unused code. Avoid
2309 sorting all the symtabs, when all we have read here is psymtabs.
2310 The symtabs are sorted as they are created anyway. Tell
2311 condense_misc_bunches whether we're mainline.
2312 (psymtab_to_symtab_1): Pass filename when recursing, to make
2313 stack trace more informative.
2314 (parse_partial_symbols): Assume cur_hdr as argument.
2315 (read_mips_symtab): Don't clobber cur_hdr, so it can be freed.
2316 Pass cur_hdr implicitly to parse_partial_symbols. Avoid checking
2317 the TYPE_NAME of char *, since that's done in symfile.c.
2318 (free_numargs, parse_symbol, add_symbol, add_block,
2319 shrink_linetable): Declare these fns void.
2320 (upgrade_type): Convert tree of if's to switch. Clean up
2321 bogus "off == 0" handling with a complaint. Avoid setting
2322 field bitpos and bitsize of array with lower and upper bounds.
2323 Check specified bitsize of elements against their actual type's
2324 bitsize, and complain if different. Complain about unknown
2326 (parse_fdr): Don't assume sizeof(char *) == sizeof (struct *).
2327 (psymtab_to_symtab_1): Print names of subsidiary files that
2328 are being read in. FIXME, we read far too many files. This code
2329 is not the problem, the problem is in parse_fdr where the psymtabs
2331 (cross_ref): Result should indicate that we used one aux entry
2332 normally, or two if we encountered a "next" entry. This used
2333 to leave the caller pointing at the wrong aux entry.
2334 (add_symbol): If overflowed cur_block, reallocate it larger,
2335 chase all pointers to it, and complain(), rather than clobber memory.
2336 (shrink_block): Use xrealloc rather than xmalloc-and-copy.
2337 (new_field): Only allocate one field initially, not two.
2338 Pull ++ out of macro argument. Simplify.
2339 (_initialize_mipsread): Avoid initialization of importd
2340 global_psymbols and static_psymbols.
2342 * symfile.c (psymtab_to_symtab): Depend on XXX_psymtab_to_symtab
2343 to properly set pst->symtab; avoid searching for it.
2344 (symfile_fns): Improve comments, add a FIXME.
2345 * dbxread.c: Update comments to reflect symfile protocol.
2346 (read_ofile_symtab, end_symtab): Return the symtab.
2347 (psymtab_to_symtab_1): Set pst->symtab.
2349 * coffread.c (coff_symfile_read): tell condense_misc_bunches
2350 whether we're mainline.
2352 * symfile.h (sym_fns): Remove unused sym_discard member.
2353 * coffread.c, mipsread.c, dbxread.c: Remove XXX_symfile_discard.
2355 * mtrace.c (mtrace): Take effect if mallwatch is set, even if
2356 the environment variable is not.
2357 * infcmd.c (finish_command): Use filtered printfs.
2358 * cplus-dem.c: Add struct tags to a few unnamed structs.
2359 * valops.c (value_coerce_array): Improve comments.
2360 * valprint.c (type_print_varspec_suffix): Print array size only
2361 if greater than zero.
2362 * m88k-tdep.c: Shift some lines left by one space, that had
2363 apparently been trashed at some point.
2364 * TODO: More things to do, a few got done.
2366 Thu Jul 18 22:46:05 1991 John Gilmore (gnu at cygint.cygnus.com)
2368 * symtab.h (LOC_EXTERNAL): Eliminate in favor of LOC_STATIC.
2369 (ldsymoff, ldsymlen, globals_offset, statics_offset): Improve
2371 * dbxread.c (read_dbx_symtab): LOC_EXTERNAL -> LOC_STATIC.
2372 * expread.y, findvar.c, symmisc.c: Ditto.
2373 * printcmd.c (address_info): Update printed forms of LOC_
2374 symbols. Elim LOC_EXTERNAL.
2375 (print_frame_args): Keep track of param stack offsets before
2376 re-looking up to find the local register param is kept in.
2378 * mipsread.c: Use <symconst.h> and <sym.h> rather than <syms.h>.
2379 Further integration of mipsread into gdb. Eliminate unused
2380 routines, duplicate declarations. Handle static symbols in
2381 psymtabs as well as external symbols. When reading symtabs,
2382 insert symbols into the correct block (global, static, or a local
2384 (read_mips_symtab, parse_partial_symbols): Don't pass useless
2386 (mipscoff_symfile_read): Don't call select_source_symtab.
2387 (parse_symbol): Use SYMBOL_VALUE_ADDRESS where appropriate,
2388 rather than SYMBOL_VALUE.
2389 (parse_external): Comment clobbering of top_stack.
2390 (parse_partial_symbols): Update comments. Allocate and parse
2391 static symbols as well as external symbols. FIXME, enum values
2392 are not handled in this pass, but should be. Inline new_psymbol.
2393 Use SYMBOL_VALUE_ADDRESS.
2394 (psymtab_to_symtab_1): Read symbols into global static block
2395 by default (until enter some function's local block context).
2396 (sort_blocks): Clean up STATIC_BLOCK as well as GLOBAL_BLOCK.
2397 (destroy_all_symtabs, new_psymbol): Eliminate, unused.
2399 * source.c (select_source_symtab): Select a source symtab
2400 from either the symtabs or, failing that, the psymtabs.
2401 (list_command): Update error message.
2402 (forward_search_command, reverse_search_command): Use getc, not
2403 fgetc, for speed. FIXME, add comment about buffers that die if
2404 overrun by long line.
2406 * values.c (unpack_field_as_long, modify_field): Avoid shifting
2407 by an entire word, which is not portable, if we have a 32-bit
2408 field. (Code in dbxread.c already turns such bitfields, if
2409 aligned, into ordinary ints, but fixing this will help for other
2410 symbol formats and for future changes.)
2411 * core.c (core_open): Handle ANSI const brain death.
2412 * utils.c (vprintf): Fix varargs typo.
2414 Sun Jul 14 00:42:53 1991 John Gilmore (gnu at cygint.cygnus.com)
2416 * findvar.c (find_var_value): Handle &function better.
2417 * TODO: Document work needed on &fn and &array.
2418 * printcmd.c (print_address_symbolic): New arg is the prefix
2419 to print if a name is printed.
2420 (print_address_demangle): Honor "set print address" now.
2421 Use new arg above to improve spacing of output.
2422 * valprint.c (val_print): When printing function pointers,
2423 print symbolic form too.
2424 * breakpoint.c (breakpoint_1): Use new print_address_symbolic.
2426 Mon Jul 8 19:02:46 1991 John Gilmore (gnu at cygint.cygnus.com)
2428 * core.c (memory_error): Reword error msg to mislead less.
2430 * mips-pinsn.c (print_insn_arg 'd'): Print $ with reg name.
2432 * mipsread.c (read_mips_symtab, read_the_mips_symtab,
2433 parse_partial_symbols): Use newer BFD internals (external_filehdr
2434 and external_aouthdr), byte-swap the fields that we care about
2435 before using them, and make the file header data local to
2436 read_the_mips_symtab rather than global.
2438 Sat Jul 6 01:34:15 1991 John Gilmore (gnu at cygint.cygnus.com)
2440 * ns32k-opcode.h (movmw, movmd): Fix opcodes. Bug fix
2441 from Rune Nerg}rd <runene@ifi.uio.no> on 5 Jul 1991.
2443 * main.c (command_line_input): Flush stdout and stderr
2444 before every call to readline. This reportedly fixes a bug
2445 that comes up in Sys V running emacs-gdb and/or xxgdb,
2446 when stdin/out are pipes or sockets.
2448 Thu Jul 4 14:47:06 1991 John Gilmore (gnu at cygint.cygnus.com)
2450 * configure.in, Makefile.in: Avoid rebuilding "depend" as much.
2451 Avoid declaring Makefile dependencies, because GNU Make stupidly
2452 tries to update it if we do.
2454 * coffread.c: Revise for minor changes to bfd internal coff
2457 * configure: If -template= is given a relative path, make it
2458 absolute before recurring in subdirectories.
2460 * configure, configure.in, Makefile.in: Install "configure" script
2461 as replacement for config.gdb.
2462 * config.gdb, Makefile.dist, Makefile.sdir: Remove
2463 * README: Update for configure, mostly. FIXME.
2465 * Add dec3100 as equivalent to littlemips. Indicate in all host &
2466 target config files that they are for the host. When the lines
2467 get copied into the Makefile, this makes it more obvious what's
2470 Mon Jun 24 23:49:07 1991 John Gilmore (gnu at cygint.cygnus.com)
2472 * sparc-opcode.h (trap opcodes): Avoid leading spaces or
2473 tabs, which end up in the disassembler output inadvertently.
2475 Wed May 29 23:01:03 1991 John Gilmore (gnu at cygint.cygnus.com)
2477 Make it compile cleanly in an ANSI GCC2 environment.
2479 * blockframe.c: <stdio.h>
2480 * cplus-dem.c: free takes a void *, ifdef __STDC__
2481 * dbxread.c (read_huge_number): avoid gcc2 bug hoisting calc of
2483 * defs.h (alloca): Avoid doing anything if alloca already def'd.
2484 * stddef.h, stdlib.h: Remove these files.
2485 * symtab.c: Avoid declaring qsort, close.
2486 * symfile.c: Avoid declaring close.
2487 * utils.c (vprintf): Declare "ap" arg as proper va_alist.
2488 * sparc-tdep.c: Avoid including lots of Sun-host-specific files.
2490 Assorted other changes.
2491 * dbxread.c: include "libaout.h", not "liba.out.h".
2492 * printcmd.c (print_frame_args): Set recurse properly for
2493 indentation of struct and array parameters.
2494 * valops.c (value_cast): Allow cast to void.
2495 * infrun.c (resume): If NO_SINGLE_STEP, call machine dependent
2496 single_step() in a target-independent fashion.
2497 * sparc-tdep.c (single_step): Don't call ptrace ourselves, just
2498 set up to be ready to continue. This makes us target independent.
2499 * infptrace.c (child_resume): Remove call to single_step; now
2500 can single step a SPARC target of any kind.
2502 Wed May 22 18:18:24 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
2504 * Makefile.dist, doc/gdb.texinfo, doc/*-m4.texinfo: split up GDB
2505 docn into separate sections---basically chapters, plus two loose
2506 pieces that can be configured to go in different places. This
2507 allows GNU m4 to preprocess the manual without coredumping.
2509 * Makefile.dist: tell TeX where to find texinfo.
2511 Mon May 20 12:15:04 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
2513 * Makefile.dist, doc/gdb.texinfo: respectively create, and use,
2514 the new target "rdl-apps.texinfo" which captures the Makefile
2515 variable that records where to find the Readline libraries.
2517 Sun May 19 05:36:59 1991 John Gilmore (gnu at cygint.cygnus.com)
2519 * tahoe-pinsn.c: #include "tahoe-opcode.h", not "opcode.h".
2520 * tm-tahoe.h (FIX_CALL_DUMMY): Ignore more parameters.
2521 * defs.h (const, volatile): Only define if not already defined.
2522 * Makefile.dist (gdb.tar.Z): Create doc subdir w/out CVS/RCS crud.
2524 * README: Update for release 3.95.
2525 * config.gdb: Don't create readline dir in subdir builds.
2526 * main.c: Include with "..." form for non-system include files,
2527 so "gcc -MM" for "make depend" works.
2528 Include readline files with "...h" rather than <readline/...h>.
2529 * mipsread.c: Include "ecoff.h" rather than "intel-coff.h".
2531 * coffread.c: Undo minor damage done by Rich Pixley. Use
2532 different internal and external representations of COFF
2533 data structures. Use new BFD routines for swapping them in and
2535 * symfile.c (free_named_symtabs): Avoid freeing file names that
2536 are null or empty. Old i960 tools seem to produce files that
2537 claim to have empty names, causing each successive file read
2538 to blow away the previous one.
2539 * sparc-xdep.c (deferred_stores): Repair minor damage by Rich.
2540 Move deferred_stores to top of file, but don't separate its
2541 #define's from its variable. Add commentary.
2542 * Makefile.dist: Fix Rich damage; undo "configure" changes in
2543 favor of keeping the (working) config.gdb. Move readline
2546 Fri May 17 12:49:56 1991 Per Bothner (via gnu at cygint.cygnus.com)
2548 * dbxread.c (read_struct_type): Try to handle g++ version 1 MI
2550 * infptrace.c (fetch_registers): no result, since now void.
2551 * tconfig/news: target depends on m68k-tdep too.
2553 Fri May 17 14:40:14 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
2555 * Makefile.dist: added readline/inc-*.texinfo to dependencies for
2558 * readline/inc-history.texinfo, readline/inc-readline.texinfo:
2559 applied various small fixes due to or inspired by RMS comments
2561 * doc/gdb.texinfo: finished using all RMS comments, save those for
2562 appendices on readline and cmd history (which are in other source
2565 Thu May 16 18:06:05 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
2567 * doc/gdb.texinfo: (1) Updated w/ref to RMS comments through
2568 chapter 9; (2) documented 'break' command's menu mode for
2569 overloaded names, in response to hgs problem report C++ p-31
2571 Wed May 15 11:02:48 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
2573 * doc/gdb.texinfo: (1) better introductory example; (2) more
2574 consistent use of @code, @samp, @file, @kbd throughout; small
2575 cleanups to first three nodes; (3) new "Contributors" node;
2576 (4) Appendix, Renamed Commands; (5) divert specialized startup
2577 instructions to "Targets" chapter for generic manuals, while
2578 leaving them up front for manuals specific to specialized
2579 environments; (6) apply fixes from RMS comments through chapter 4.
2581 * pretex.m4: modify explanatory text slightly (and redefine
2582 "regexp") to keep GNU m4 from complaining. (It still crashes
2583 later, but one step at a time...)
2585 Wed May 15 10:32:12 1991 John Gilmore (gnu at cygint.cygnus.com)
2587 * readline/readline.c (update_line): Avoid dereferencing a pointer
2588 before comparing it to its bounds. Saber caught this.
2589 (init_terminal_io): Don't set BC from the "pc=" termcap variable,
2590 and only set PC if tgetstr returned non-null. Saber caught this.
2592 Tue May 14 16:29:53 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)
2594 * Makefile.dist: put gdb.dvi stuff (updated to use M4 preprocessor
2595 stuff for config manual) here where it counts; updated
2596 to use new subdir structure (gdb/doc/).
2598 * Makefile: generated from above via
2602 * gdbint.texinfo: added instructions on generating gdb.info* files
2603 locally for release. These are ordinary info
2604 files, formatted from gdb.texinfo (via gdb-all.texinfo, see
2605 Makefile)---but due to use of texinfo 2, can't count on makeinfo
2606 to generate these, so we distribute them already formatted.
2608 * gdb.texinfo: included full Info node and menu crud (as generated
2609 by C-u M-x texinfo-master-menu using the texinfo-2 elisp code).
2611 * Makefile: updated "gdb.dvi" target to use M4 preprocessor;
2612 put in comments-for-future gdb.info target (one day makeinfo will
2615 Tue May 14 13:51:36 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)
2617 * gdb.texinfo: Updated to include new or old undocumented
2618 commands, at least the following (perhaps some others I forgot to
2619 record): info f, info float, info path, info program, info s, info
2620 set, info source, info terminal, info types, info user, set/show
2622 Also covered all recent GDB command renames for v4.
2624 Mon May 13 14:57:46 1991 John Gilmore (gnu at cygint.cygnus.com)
2626 * mipsread.c: Rather than keeping count of how many symtabs
2627 and psymtabs we have, for sorting purposes, count them when
2628 we need to sort. This fixes bug in rereading of symbol tables.
2630 Fri May 10 15:43:33 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)
2632 * infcmd.c: renamed "info path" to "show paths"

2647 symtab.h, target.c, target.h: Lint.
2648 * core.c: setup and select frame after reading shared libs,
2649 else reading shared libs will clobber them. Lint.
2650 * utils.c (error): Force out any buffered wrap text.
2652 Fri May 3 22:01:56 1991 John Gilmore (gnu at cygint.cygnus.com)
2654 * remote.c: Remove decls of memory_insert_breakpoint
2655 and memory_remove_breakpoint, no longer used. (Suggestion of
2658 * Makefile.dist: use ${subdir} in paths of BFD and LIBIBERTY,
2659 to make it easier to interface to "configure"'d libraries.
2661 Fri May 3 13:10:01 PDT 1991 Roland Pesch (pesch at fowanton.cygnus.com)
2663 * valprint.c: introduce "set p", "set pr", "show p" and "show pr" as
2664 aliases for set/show print.

2753 * infptrace.c (PT_WRITE_D, PT_READ_D): Use correct values.
2754 (This still doesn't seem to make MIPS bkpts work.)

2790 : Lint. Use read_memory not read_memory_integer on CORE_ADDR's.
2791 Use {value_as,unpack}_pointer (added to values.c)
2792 not {value_as,unpack}_long on CORE_ADDR's.
2793 Use longest_to_int (added to defs.h) instead of cast to int.
2794 Remove from_tty arg to mod_path.
2795 Put symfile_bfd in {coff,dbx}read.c not symfile.h.
2796 Use OP_NULL instead of 0 where dummy enum exp_opcode needed.

2871 rather than smash_to_method_type.
2872 symtab.c, symtab.h (allocate_stub_method): New function.
2873 dbxread.c (read_type): If we get "##", don't lookup_function_type
2874 and start clobbering it; allocate_stub_method instead.
2875 * printcmd.c (x_command): Dereference references.
2876 * valprint.c (type_print_varspec_prefix, case TYPE_CODE_METHOD):
2877 Don't print " " type_print_base (...) "::" if !passed_a_ptr.

2882 * values.c: Move declaration of cplus_demangle to top of file.
2883 * values.c (baseclass_addr): If can't read memory, set *ERRP

3215 * dbxread.c (read_dbx_symtab): Allow N_SOL to cleanly take us back
3216 to the main file, as well as to include files. Also, put global
3217 functions into the global psymtab, to make "i fun" work.
3218 (end_psymtab): Free named symtabs and psymtabs for a file, once a
3219 new psymtab for it has been read.
3220 * coffread.c (end_psymtab): Free named symtabs and psymtabs for
3221 a file, once a new symtab has been read for it.
3222 * mipsread.c: FIXME. We need to do the same for MIPS, but it

3224 queued to the psymtab list.
3226 * symfile.c (symbol_file_add): Use filtered printing and wrap it.
3227 If we have wiped out any old symbol tables, clean up at end of

3243 static psymbols list.
3244 (types_info): Restore this function from its untimely #if 0.

3267 (dbx_psymtab_to_symtab): symfile might be zero, cope.
3268 * exec.c (exec_ops): Add_syms_addr is valid in our tvec.
3269 (set_section_command): New command ("section xxx yyy" -- should
3270 be renamed to "set section xxx yyy" FIXME) which sets the
3271 base address of a section of the exec file, overriding the
3272 virtual address that BFD reports.
3274 Fri Apr 5 17:14:39 1991 John Gilmore (gnu at cygint.cygnus.com)
3276 * exec.c: Add add_syms_addr_command to exec_ops, so you can

3281 * tm-i386v.h (FLOAT_INFO): Don't define it, since the code
3282 for printing the float info is host-dependent, not
3283 target-dependent. FIXME.
3284 * i386-pinsn.c: Move #includes to top, remove useless ones.
3285 * i386-tdep.c: Don't bother including <.../reg.h> since we
3286 don't use it (and it doesn't exist on host systems).
3288 * ieee-float.c (ieee_extended_to_double): Convert NaN to Inf.
3289 Convert negative numbers properly.
3290 (ieee_test): Make numbers really random; fix format arg.
3292 * infcmd.c (attach_command, detach_command): Don't repeat on CR.
3293 * core.c (core_detach): Unpush core_ops, which might not be on
3294 top. We used to just pop the top, which broke things. Don't
3295 need dont_repeat() any more.
3296 (core_file_command): Psst! Don't repeat it.
3297 * remote-nindy.c (nindy_detach): Don't need dont_repeat() now.
3298 * expprint.c (print_subexp): Avoid switch fallthru on
3299 BINOP_ASSIGN_MODIFY, so we can print += and such.
3300 * frame.h: Fix typo.
3301 * inflow.c (kill_command): After killing inferior, print our
3302 current frame in the core file, if we have one.
3303 (generic_mourn_inferior): When inferior dies, either select
3304 the current frame (in the new target, e.g. core file), or
3305 set both the current and selected frames to NULL.
3307 Changes from Peter Schauer.
3309 * infptrace.c: Avoid <sys/ptrace.h> on USG.
3311 * Make all file names fit in 14 characters (sigh and damn!):
3312 mv hp300hpux-xdep.c hp300ux-xdep.c
3313 mv symmetry-xdep.c symm-xdep.c
3314 mv symmetry-tdep.c symm-tdep.c
3315 mv convex-opcode.h convx-opcode.h
3316 mv tm-vxworks960.h tm-vx960.h

3319 mv gdb-int.texinfo gdbint.texinfo
3320 mv remote-sa.m68k.shar rem-m68k.shar
3321 mv remote-multi.shar rem-multi.shar
3322 * Makefile.dist, README, config.gdb, convex-pinsn.c,
3323 tconfig/symmetry, tconfig/vxworks960, tconfig/vxworks68,
3324 xconfig/hp300hpux, xconfig/symmetry: Change names to shorter
3327 * command.c (user_info_1, user_info): New command for listing
3328 the user-defined commands.
3330 Wed Apr 3 15:00:26 1991 John Gilmore (gnu at cygint.cygnus.com)
3332 * dbxread.c (really_free_pendings): Clear file_symbols
3333 and global_symbols after freeing them; otherwise, running
3334 this function twice (if it appears twice on the cleanup
3335 chain), we try to free things twice.
3337 * dbxread.c (read_dbx_symtab): Calculate end_of_text_addr
3338 based on text_addr (the address of text in core), not on addr (the
3339 offset between text in the .o file and in core). This change
3340 is from Peter Schauer.
3342 * main.c: Define ALL_CLEANUPS as a cast of zero.
3343 (return_to_top_level): Use it.
3344 (main): Do all cleanups after each command run as part
3345 of the gdb startup sequence. Also do all cleanups before
3346 entering the command loop, and every time we exit the command
3347 loop and reenter. Before, the cleanups from the startup sequence
3348 were being left undone until the first error!
3349 (command_loop): Rename do_nothing cleanup to command_loop_marker
3350 so we can see it easily when examining the cleanup chain.
3351 (init_signals): Add another do_nothing for signal handling.
3352 (quit_command): Only try to kill target if it has execution.
3353 Problems in the target stack got us into a state where
3354 inferior_pid was nonzero but none of the targets had execution.
3355 In this state you couldn't exit gdb.
3357 * dbxread.c: Two changes from Peter Schauer.
3358 (echo_command): Fflush output after an echo command.
3359 (show_history): Pass all args to cmd_show_list.
3361 * utils.c (init_malloc): Call mtrace to turn on tracing
3362 if the environment variable MALLOC_TRACE is set to a file name.
3363 * mtrace.c: Add source file which provides a log of every malloc,
3364 free, and realloc to a trace file.
3365 * mtrace.awk: Add source file which analyzes the trace file.
3366 * Makefile.dist (GNU_MALLOC, MALLOCSRC): Add mtrace.{c,o,awk}.
3367 (VERSION): Roll to 3.94.3.
3369 * breakpoint.c (breakpoint_1): Add a space to "i watch" output.
3370 (check_duplicates): Don't bother with watchpoints.
3371 (set_raw_breakpoint): Comment about danger of this routine.
3372 (watch_command): Parse and eval all args before calling
3375 * solib.c (find_solib): Avoid error in referencing memory to
3376 see if any more shared libraries have been added. This is
3377 particularly useful if the target has terminated. Bug reported
3380 Changes from Peter Schauer <pesrem@regent.e-technik.tu-muenchen.de>
3381 in bringing up 3.94.2 on the Sun-3.
3383 * Makefile.dist: Include CFLAGS in rule for cplus-dem.o.
3384 * breakpoint.c (enable_breakpoint): Check for valid watchpoint
3385 expression (in scope) before reenabling watchpoint.
3386 * signame.c (init_sigs): Add missing declaration of i, fix
3387 sys_siglist declaration.
3388 * source.c (list_command): Fixed range computation to use
3390 * stack.c (backtrace_command): Do not allow command if target has
3391 no stack, print informative error message.
3392 * target.c (target_command): Do not write into command line
3393 because this fails if the target command is used in a user defined
3394 command. [This change was enhanced by gnu to support any-
3395 unique-prefix matching on target names.]
3396 * valops.c (value_struct_elt): Avoid infinite loop on an
3397 erroneous attempt to print the member of function (try p main.p).
3399 Mon Apr 1 17:05:45 1991 John Gilmore (gnu at cygint.cygnus.com)
3401 * expread.y (name_no_typename): Avoid reduce/reduce errors
3402 caused by ambiguity in handling NAME_OR_INT and NAME_OR_UINT.
3403 Since the GDB parser really doesn't use name_no_typename in a
3404 name-only context, the parser can't tell the diff between
3405 names and numbers here. Avoid allowing a name_no_typename
3406 to be a NAME_OR_*INT to resolve the conflict.
3408 Sun Mar 31 20:12:07 1991 John Gilmore (gnu at cygint.cygnus.com)
3410 Bugfixes from Mark Fox (markf@wrs.com) (test=testField.c):
3412 * valprint.c (val_print_fields): bitfield printing didn't handle
3413 byte order. Indirect through a few more fns to cope.
3415 * values.c (modify_field): also cope with byte order.
3417 Sat Mar 23 10:02:21 1991 John Gilmore (gnu at cygint.cygnus.com)
3419 Cleanup for release 3.94.2:
3421 * Makefile.dist: Pull REMOTE_OBS. Fix saber includes for BFD
3422 include files. Roll version to 3.94.2.
3424 * coffread.c (init_stringtab): Read length into unsigned char
3425 array before swapping; don't assume 32-bit longs.
3427 * target.c (target_info): Don't bother with get_sym_file, just use
3428 the symfile global variable.
3429 * symtab.h, symfile.c (get_sym_file): Delete it.
3431 * dbxread.c (dbx_symfile_init): Don't depend on long == 4 bytes.
3432 (define_symbol): Set symbol line number to 0 if not gcc-compiled.
3433 (read_type): Replace one more error() with complain().
3435 * mipsread.c (parse_partial_symbols): Replace printf with complain.
3437 * i960-tdep.c: Fix copyright attribution.
3439 * config.gdb: Quote all backquotes in doublequotes. You can
3440 quote me on that. BSD 4.4 shell found this one.
3442 * infptrace.c (throughout): The third argument to ptrace is an
3445 * infrun.c (wait_for_inferior): When program has terminated, we
3446 have to call target_terminal_ours before we pop that target off
3447 the stack (e.g. before a call to target_kill or
3448 target_mourn_inferior). This fixes problem where a program
3449 terminates, then GDB stops for (tty output) and you have to type
3450 "fg" to the shell to resume it. FIXME: This code for what to
3451 do after termination really should be in normal_stop instead.
3453 * gdbcore.h (read_memory_check): Change declaration; it changed
3456 * terminal.h: Include <sgtty.h> before <sys/ioctl.h>, since in BSD
3457 4.4 prereleases, this avoids a bug in their sgtty compatability
3459 * remote.c: Use terminal.h rather than hand-rolling the same.
3461 * signame.c, signame.h (psignal): Arg is unsigned, not int.
3462 * utils.c (strsave, strstr): Fix arg types.
3463 * valprint.c (val_print): lint
3465 MIPS symbol table support from Per Bothner:
3467 * symfile.c (symtab_fns): Remove initializer table that needs to
3468 be hacked for each new symbol file format supported.
3469 (add_symtab_fns): New function, chains symbol table
3470 handlers into the global list.
3471 (symfile_init): Search this list.
3472 * symfile.h: Add next pointer, declare add_symtab_fns.
3473 * coffread.c (_initialize_coffread): Call add_symtab_fns.
3474 * dbxread.c (_initialize_dbxread): Call add_symtab_fns.
3476 * mipsread.c (psymtab_to_symtab_1): return void instead of (struct
3477 symbol *). Thus, we no longer need the hack to trash
3478 pst->filename. Good, since that hack confused code in symfile.c!
3480 (reorder_symtabs, destroy_all_symtabs): Removed static
3481 all_symtabs, which was used to qsort symtabs in reorder_symtabs.
3482 Instead, the latter now uses a temporary array (stack-allocated
3483 from an obstack, and then freed).
3485 (parse_symbol): Added a hack to fix up BLOCK_{START,END} if they
3486 haven't been set in the outermost stBlock of a procedure. This was
3487 a problem with f77 binaries on Ultrix 4.?.
3489 (new_symtab, new_symbol, new_type): Continue changing code to use
3490 obstacks more and otherwise conform to dbxread internal style.
3491 Made the free_code of symtabs be free_linetable (as in dbxread)
3492 instead of free_contents. This implies memory leaks when reading
3493 a new symbol table, until the conversion is finished. Did change
3494 (struct symbol) and (struct type) to be allocated on the
3495 symbol_obstack. Blocks and blockvectors are among the things
3498 * mipsread.c (parse_partial_symbols, parse_fdr): It hasn't been
3499 tested much, but it solved one problem (reported by Meissner), and
3500 cleans up some other things. The problem happened when an
3501 included file contains actual code (functions) and not just
3502 definitions. The mips coff is a little inconvenient there, since
3503 it may cause a procedure to be mapped to the wrong psymtab.
3505 * mips-tdep.c (heuristic_proc_desc): Minor cleanup.
3506 * mips-xdep.c (fetch_core_registers): Minor cleanup. FIXME,
3507 this will need work for the new core paradigm.
3509 Opcode patches from the net:
3511 * mips-opcode.h: fix incorrect disassembly of the mfc1, cfc1, and
3512 ctc1 instructions. Also, the cvt.d.w and cvt.s.w instructions were
3513 missing altogether - they are added here. From Bruce Bauman.
3514 * mips-opcode.h: The low mask for C0 instructions was too small.
3515 From Garrett Lau. I modified the fix to check the entire 32-bit
3518 * ns32k-opcode.h: Fix opcodes for deiw and deid. From Bruce
3521 Thu Mar 21 12:56:46 1991 John Gilmore (gnu at cygint.cygnus.com)
3523 Roll in changes from Per Bothner (Tue, 25 Sep 90 11:11:04):
3525 * dbxread.c (read_type): Pointer subtraction (value_sub in
3526 valarith.c) sometimes failed because the types of the
3527 pointers being subtracted were not identical.
3528 These differed because dbxread.c was allocating pointer types
3529 using dbx_alloc_type+smash_to_pointer_type instead of
3530 lookup_pointer_type. I failed to find a justification for the
3531 former, so I changed it to use the latter. Similarly, I
3532 replaced smash_to_function_type by lookup_function_type,
3533 and smash_to_reference_type by lookup_reference_type.
3535 * mipsread.c (parse_symbol, upgrade_type, parse_procedure,
3536 _initialize_mipsread): corresponding changes.
3538 * symtab.c (smash_to_{pointer,reference,function}_type): eliminate.
3540 * source.c (mod_path): Do tilde_expand on each component of the path,
3541 rather than on the (list of) paths as a whole.
3542 (print_source_lines): Set first_line_listed in addition to
3543 current_source_symtab and current_source_line. If the source was
3544 not findable, after a "dir" command to fix the problem,
3545 a "list" would get the wrong lines.
3547 While I was there... (gnu):
3549 * dbxread.c (read_type): Change error to complaint.
3551 Thu Mar 21 12:56:46 1991 John Gilmore (gnu at cygint.cygnus.com)
3553 First attempt at detailed understanding of symbol table memory alloc.
3555 * dbxread.c (dbx_symfile_read): Free our string table if we
3556 aren't the mainline. Free the "info" struct since we're done with
3558 (init_psymbol_list): Free any previously allocated psymbol lists.
3559 (): FIXME: Should realloc-down the psymbol lists when done reading
3560 the main symbol file?
3562 * symmisc.c (free_symtab): Free fullname field too.
3564 * xm-hp300hpux.h (USG): #undef then #define so Makefile can -D.
3565 (REGISTER_ADDR): Make result type unsigned int.
3567 * xconfig/{i386*,hp300hpux,altosgas,altos}: All config files that
3568 define REGEX must also define REGEX1 (its dependency).
3570 Tue Mar 19 21:28:57 1991 John Gilmore (gnu at cygint.cygnus.com)
3572 * tconfig/i960: No longer works, points you at vxworks960 or
3575 * xgdb.c, XGDB-README: Remove file. Users can get the much
3577 * Makefile.dist: Remove all trace of xgdb.
3579 * breakpoint.c (breakpoint_1): Pass demangle arg to
3580 print_address_symbolic.
3581 (clear_breakpoints): Remove unused function.
3582 (breakpoint_re_set_one): Guts of breakpoint_re_set.
3583 (breakpoint_re_set): Use catch_errors to do them all anyway.
3585 * gdb-int.texinfo (Host versus Target): Add section on what is
3586 a "host" feature versus what is a "target" feature.
3588 * infcmd.c (path_command, path_info): Handle the PATH variable
3589 (object search path) as conveniently as the source search path.
3590 * environ.c (set_in_environ): Set some vars in GDB's environment,
3591 in addition to the child's. PATH, G960BASE, G960BIN for starters.
3592 * source.c (mod_path): New function, from guts of
3593 directory_command, modifies a path. Used by path_command.
3594 (directory_command): Call it.
3595 * defs.h (strsave): Declare.
3597 * utils.c (sevenbit_strings): Add new printing option.
3598 (printchar): Use it.
3599 (strsave): Provide this handy helper routine.
3600 (set_width_command): Rename set_screen_width_command.
3601 (_initialize_utils): "set screen-width" => "set width";
3602 "set screen-height" => "set height"; add sevenbit-strings.
3604 * infcmd.c (do_registers_info): Print floating point registers
3605 in raw hex as well as float format, regardless of whether it is
3606 a "virtual" convertible register.
3607 * tm-sparc.h (PRINT_REGISTER_HOOK): Print every pair of float
3608 regs as a double, just in case it's being used that way.
3609 * values.c (unpack_long): Comment on array/function coercion.
3610 (unpack_double): Argument is in target byte order now. For
3611 integer arguments, just call unpack_long and float the result.
3612 * m68k-tdep.c: include defs.h for "const" handling.
3613 * remote-nindy.c: Use ieee-float stuff.
3614 (nindy_fetch_registers): Unpack double regs to host double, then
3616 (nindy_store_registers): Pack extendeds to host double, flip
3617 around by misusing unpack_double, send as target double.
3619 * tm-vxworks68.h (FRAME_CHAIN): Handle current frame pointer of
3620 zero, as when stopped at the first instruction of a process.
3622 * blockframe.c: Fix filename in comment (param.h => tm.h).
3623 * sparc-tdep.c (skip_prologue): More explicit nudging comments.
3624 * tm-68k.h: Fix typos.
3626 Fri Mar 15 01:09:34 1991 John Gilmore (gnu at cygint.cygnus.com)
3628 Changes from a bringup on the DEC Vax under Ultrix 4.0.
3630 * coredep.c (fetch_core_registers): Pass end-address of register
3631 section to register_addr as expected. Don't call supply_register
3632 if we'd just pass it garbage.
3634 * dbxread.c (read_dbx_symtab): Skip N_NSYMS on Ultrix.
3636 * exec.c (xfer_memory): Use boolean xfer_fn result, not int.
3638 * target.c (push_target, target_info): Cast enums to int for < or
3641 * stack.c (print_frame_info): Identify source file & line
3642 even if we can't print it.
3644 * xm-vax.h (MISSING_VPRINTF): No longer missing in Ultrix V4.0.
3646 Sat Mar 9 10:08:20 1991 John Gilmore (gnu at cygint.cygnus.com)
3648 Clean up IEEE floating point support.
3650 * ieee-float.h: New file.
3651 * ieee-float.c: Write real routines to convert between host
3652 doubles and various target IEEE extendeds.
3653 * m68k-xdep.c: Eliminate assembler code for extended floats.
3654 * xconfig/{3b1,altos,altosgas,hp300bsd,isi,news,news1000,sun2os3,
3655 sun2os4,sun3,sun3os3,sun3os4}: Eliminate use of m68k-xdep.o.
3656 * tm-i960.h, tm-68k.h (REGISTER_CONVERT_TO_VIRTUAL,
3657 REGISTER_CONVERT_TO_RAW): Use ieee_extended_to_double and
3658 double_to_ieee_extended.
3659 * i960-tdep.c: Define ext_format_i960.
3660 * m68k-tdep.c: Define ext_format_68881.
3661 * sparc-tdep.c: Define ext_format_sparc, though unused.
3662 * Makefile.dist (HFILES): Add ieee-float.h.
3663 * inftarg.c: #include "ieee-float.h" for the REGISTER_CONVERT
3666 Obsolete the "coffstrip" program in favor of using BFD's strip.
3668 * nindy-share/coffstrip.c: Remove file.
3669 * nindy-share/nindy.c (coffstrip): Routine to run bfd_strip.
3670 * Makefile.dist: Remove references to nindy-share/coffstrip.c.
3671 * tconfig/nindy960: Remove reference to coffstrip.o.
3673 * Makefile.dist: Roll version number to 3.94.1 (not yet final).
3675 Wed Mar 6 09:56:45 1991 John Gilmore (gnu at cygint.cygnus.com)
3677 * symfile.h: Add symfile_bfd, common between dbxread and coffread.
3678 * dbxread.c: Remove static symfile_bfd.
3679 * infcmd.c (do_registers_info): Add PRINT_REGISTER_HOOK, though
3681 * inftarg.c (child_detach): Pop the child_ops vector if the
3682 detach is successful.
3683 * remote-nindy.c (nindy_create_inferior): Don't push a new
3684 nindy_ops since nindy uses the same one for execution and memory
3686 * core.c (core_ops): Use child_attach and child_create_inferior
3687 rather than default attach and create_inferior functions.
3689 Handle floating point registers in core files.
3691 * sparc-xdep.c (fetch_core_registers): Rewrite for float support.
3692 * sun3-xdep.c (fetch_core_registers): Rewrite for float support.
3693 This version untested since BFD doesn't yet support sun3 core
3695 * hp300hpux-xdep.c: Rewrite fetch_core_registers to new calling
3696 conventions. Fix comments and style. This version has not
3697 been compiled yet, since we have no HP inhouse.
3698 * core.c (get_core_registers): Look for two sections, ".reg"
3699 and ".reg2", and pass both to fetch_core_registers sequentially.
3701 Revise directory path yet again.
3703 * source.c (forget_cached_source_info): Not static any more.
3704 (init_source_path): New default source path is "$cdir:$cwd".
3705 (dir_command): Handle variable arguments ($cdir, $cwd).
3706 (source_info): Print "Compilation directory" rather than
3707 "Originally compiled in" to remind people of $cdir.
3708 (openp): If the path contains $cwd, use current directory.
3709 (open_source_file): If compilation directory is known, replace
3710 first $cdir in path with the compilation directory.
3711 (print_source_lines): Even if we can't print the lines, set the
3712 current symtab and line for future commands like "info source" or
3713 "breakpoint". Also, error message now contains the file name,
3714 line number, and file access error message.
3715 (_initialize_source): Fix help text to describe changes.
3716 * main.c (cd_command): Forget cached source info when we chdir.
3717 * utils.c (strstr): Add simple implementation.
3719 Tue Mar 5 01:41:40 1991 John Gilmore (gnu at fowanton.cygnus.com)
3721 * coffread.c (read_one_sym, init_linetable, init_stringtab):
3722 Byte-swap COFF symbol tables if necessary when reading them in.
3723 Use complain() to replace error message in one spot. Needs
3724 corresponding change in bfd/coff-code.h to make some symbol
3725 swapping routines non-static.
3727 Mon Mar 4 00:53:40 1991 John Gilmore (gnu at cygint.cygnus.com)
3729 Merge changes from Eirik Fuller, for UTek.
3731 * defs.h (errno): Add declaration.
3732 * altos-xdep.c, arm-xdep.c, convex-xdep.c, gould-xdep.c,
3733 hp300hpux-xdep.c, infrun.c, inflow.c, infptrace.c, i386-tdep.c,
3734 i386-xdep.c, pyr-xdep.c, mips-xdep.c, remote-eb.c, remote-nindy.c,
3735 remote-vx.c, source.c, standalone.c, stuff.c, sun386-xdep.c,
3736 symmetry-tdep.c, symmetry-xdep.c, umax-xdep.c, utils.c: Eliminate
3737 declarations of errno.
3739 * remote-eb.c: Define B19200 and B38400 as EXTA and EXTB.
3741 * remote-vx.c: Include <sys/time.h> for UTek; Sun gets it via
3742 <rpc/rpc.h> and <rpc/types.h>.
3744 Sat Mar 2 15:47:55 1991 John Gilmore (gnu at cygint.cygnus.com)
3746 * i960-tdep.c (examine_prologue): Add new argument limit,
3747 which stops the scan at the end of the prologue, or at the PC.
3748 This fixes a problem where it walks down into the code for the
3749 user's statements if that code looks like function prologues.
3750 Mark Fox and I have been bouncing this code back and forth, making
3751 small changes to it. Callers changed to match.
3753 Tue Feb 26 01:47:07 1991 Cygnus John Gilmore (cygnus at yuba)
3755 Cleanup for gdb-3.94 release final:
3757 * Makefile.dist: Remove remote-vx.c, remote-nindy.c, and all
3758 the .c files from vx-share and nindy-share, from the various
3759 macros, since they are not found via ALLDEPFILES.
3760 (SFILES): Add tm-i960.h.
3761 (alldeps.mak rule): Break out ALLDEPFILES_MAINDIR and
3762 ALLDEPFILES_SUBDIR. List all the nindy and vxworks subdir files
3764 (TAGFILES_MAINDIR): Change ALLDEPFILES to ALLDEPFILES_MAINDIR.
3765 (gdb.tar.Z): Use ALLDEPFILES_SUBDIR as well as SFILES_SUBDIR.
3767 Mon Feb 25 16:02:35 1991 Cygnus John Gilmore (cygnus at oldman)
3769 * am29k-tdep.c: Add contribution line.
3770 (examine_prologue): Cache information about function prologues in
3771 the misc-function-vector to avoid lots of references over the
3772 serial line while examining instructions.
3774 * core.c (core_close): New function made from cleanup_core.
3776 * core.c, exec.c, inftarg.c, remote-eb.c, remote-nindy.c,
3777 remote-vx.c, remote.c, target.c, target.h,
3778 Update target_ops vector to add attach, close, and load entries.
3779 Use add_syms_addr_command, not add_file_addr_command, for
3780 add_file. Break out close routine from existing code.
3782 * dbxread.c (really_free_pendings): Don't free pending_blocks;
3783 they are in an obstack.
3784 (read_dbx_symtab): Relocate end_of_text_addr in the psymtab.
3786 (define_symbol): Add symbol type parameter; change callers;
3787 pass type parameter to DBX_PARM_SYMBOL_CLASS macro to allow
3788 it to influence the symbol class on the i960.
3789 (define_symbol): Swap LOC_CONST's into target byte order.
3791 * exec.c (exec_close): New function.
3792 (exec_file_command): Call it.
3794 * findvar.c (read_relative_register_raw_bytes): Doc byte order,
3795 Fix byte order of frame pointer.
3796 (read_var_value): Result of 0 if var's value can't be found,
3797 e.g. missing FRAME_ARGS_ADDRESS. Byte-swap LOC_CONST and
3798 LOC_LABEL values to target order. Add LOC_LOCAL_ARG.
3799 (locate_var_value): Use read_var_value and use its lazy address
3800 as the location of the var's value. Lint.
3802 * i960-pinsn.c (next_insn): Add routine from vxgdb for scanning
3805 * i960-tdep.c (arg_address, i960_frame_find_saved_regs): Remove
3806 obsolete Intel versions in favor of vxgdb versions.
3807 (check_host, byteswap, byteswap_val, reorder_val): Eliminate
3808 code dealing with byte order of values, which Intel did in host byte
3809 order rather than gdb-4's target byte order.
3810 (i960_frame_chain_valid): Move to nindy-tdep.c.
3811 (examine_prologue, skip_prologue, frame_find_saved_regs,
3812 frame_args_address, leafproc_return, saved_pc_after_call,
3813 pop_frame): Add vxgdb versions from Mark Fox.
3814 (examine_prologue, frame_struct_result_address): Add code
3815 to deal with the saved value of G13 (struct return address
3817 (frame_args_address): Modify Mark's version to prefer the
3818 saved value over the current value in the topmost frame.
3819 Cache result in the frame info to avoid performance hair in
3821 (print_fault): Add gdb960 code for printing faults.
3822 (_initialize_i960): Actually call check_host.
3824 * ieee-float.c (ieee_extended_to_double, ieee_double_to_extended):
3825 add stub routines. FIXME, these currently just return zero!
3827 * infcmd.c (program_info): Use PRINT_RANDOM_SIGNAL.
3828 (attach_command): Call target_attach, not target_open, now.
3830 * infrun.c (normal_stop): Make global, not static, for vx_attach.
3831 (child_attach): Rename from child_open.
3832 (wait_for_inferior): Use PRINT_RANDOM_SIGNAL. If stop_pc is zero,
3833 don't confuse it with a zero step_resume_break_address.
3835 * inftarg.c (child_detach): Eliminate inferior_pid test.
3836 (child_files_info): Clean up message a bit.
3837 (child_ops): Use child_attach, not child_open, to attach.
3839 * mem-break.c: #ifdef out the whole file if BREAKPOINT is not
3840 set (e.g. on VxWorks or NINDY). Move read_memory_nobpt from
3841 findvar.c to here, since it depends on the contents of the
3842 shadow_contents of breakpoints, but keep if #if 0 since it is
3845 * nindy-tdep.c: New file, contains nindy_frame_chain_valid, moved
3848 * printcmd.c (address_info): Handle LOC_LOCAL_ARG. Lint.
3849 (ptype_command, display_command): Eliminate have_inferior_p and
3850 have_core_file_p in favor of target_has_stack or
3851 target_has_execution.
3852 (print_frame_args): Handle LOC_LOCAL_ARG. Eliminate duplicate
3853 code for actually finding the values of arguments, though we still
3854 keep track of the maximum stack offset for use in printing unnamed
3855 arguments. Handle missing FRAME_ARGS_ADDRESS.
3857 * remote-nindy.c (i960_print_fault): Move to i960-tdep.c.
3858 (struct nindy_regs): Define registers passed to/from nindy.
3859 (nindy_fetch_registers, nindy_store-registers): Translate between
3860 nindy and GDB formats for the registers.
3861 (dcache_init): Statically allocate the cache, since it was being
3862 allocated by a malloc that was never freed anyway.
3863 (nindy_create_inferior): Error, not core dump, if no exec file.
3864 (nindy_before_main_loop): Use target_load, not target_add_file.
3866 * remote-vx.c (net_load): Specify large timeout for load
3867 requests. Allow user to break out with INTERRUPT.
3868 (net_break): Remove useless code, clean up. Change callers.
3869 (parse-args, skip_white_space, find_white_space): Clean up arg
3870 parsing to cope with quoted strings.
3871 (net_wait, net_quit): Never call error, just return status.
3872 (vx_read_register, vx_write_register): Cleanup status checking.
3873 #ifdef the code based on which CPU we are using (960 or 68k),
3874 FIXME, this should be completely general but it isn't yet.
3875 (vx_xfer_memory, vx_resume): Cleanup status checking.
3876 (vx_run_files_info): Improve message.
3877 (vx_load_command): Renamed from vx_add_file_command. Allow load
3879 (net_ptrace): Remove unused routine.
3880 (vx_wait): Adopt code from vxgdb960 to cope with broken
3881 connections to target machine and prompt to disconnect. Remove
3882 debug printouts. Map some EVENT_'s to SIGnals.
3883 (add_symbol_stub, vx_open): Print names of object files we found,
3884 and "ok" if we read their symbols OK. Clarify output in general.
3885 (vx_attach, vx_detach, vx_kill): Add these commands.
3886 (vx_convert_from_virtual, vx_convert_to_virtual): Simplify.
3887 (vx_run_ops): Turn off all_mem, to avoid spurious msg in the
3888 "info files" output, and create_inferior, since we already have
3891 * stack.c (frame_info): Replace Frame_unknown with 0.
3892 (print_frame_arg_vars): Handle LOC_LOCAL_ARG.
3893 (return_command): Pop until the PC matches as well as the FP,
3894 so it works even if the FP is shared with another function,
3895 as in "frameless" or "leaf" procedures.
3897 * symfile.c (load_command): renamed from add_file_target_command.
3898 (add_syms_addr_command): renamed from add_file_addr_command.
3899 (add_syms_command): Stub to call target_add_syms.
3900 (_initialize_symfile): Change command names and descriptions,
3901 add-file => add-syms, and load from alias to its own command.
3903 * target.c (kill_or_be_killed, maybe_kill_then_attach,
3904 maybe_kill_then_create_inferior): Default for attempts to start
3905 a process, if one is already running, is to ask about killing
3906 it and retry if yes.
3907 (upstack_create_inferior): #if-0 it, strata obsolete it.
3908 (push_target, unpush_target, pop_target): to_close() a target
3909 before unstacking it.
3910 (target_info): Renamed from target_files_info.
3911 (_initialize_targets): Rename "i files" as "i target", accessible
3914 * target.h: Improve comments about the target_ vectored routines.
3916 * tm-i960.h: Remove NINDY-specific stuff to tm-nindy960.h.
3917 Convert commenting style to standard GNU style.
3918 (DBX_PARM_SYMBOL_CLASS): allow LOC_LOCAL_ARG's to be recognized.
3919 (SKIP_PROLOGUE): No longer a no-op.
3920 (SAVED_PC_AFTER_CALL): Now handles leaf procedures.
3921 (*_REGNUM): Sort register numbers.
3922 (REGISTER_BYTES, REGISTER_BYTE, REGISTER_RAW_SIZE,
3923 MAX_REGISTER_RAW_SIZE, REGISTER_CONVERTIBLE,
3924 REGISTER_CONVERT_TO_VIRTUAL, REGISTER_CONVERT_TO_RAW): Float regs
3925 are now 10 byte extendeds, not 8 byte doubles.
3926 (FRAME_CHAIN_VALID): Make this config-dependent, since it differs
3927 for nindy versus vxworks targets. FIXME, this should possibly go
3928 in the target vector.
3929 (EXTRA_FRAME_INFO, INIT_EXTRA_FRAME_INFO): Cache both
3930 frame_saved_regs and arg pointer with each frame.
3931 (FRAMELESS_FUNCTION_INVOCATION): New leafproc support.
3932 (FRAME_ARGS_ADDRESS): Use cached result.
3933 (FRAME_ARGS_ADDRESS_CORRECT): New, avoids g14 guessing.
3934 (FRAME_FIND_SAVED_REGS): Change arg to subsidiary fn.
3935 (PRINT_RAMDON_SIGNAL): Call print_fault.
3936 (POP_FRAME): Now works.
3938 * tm-nindy960.h: Break this off tm-i960.h. NINDY-specific
3939 option parsing and startup; STACK_END_ADDR, FRAME_CHAIN_VALID,
3940 BREAKPOINT, and DECR_PC_AFTER_BREAK are here.
3941 (ADDITIONAL_OPTION_HANDLER): use target_load, not
3944 * tm-vxworks960.h: Break this off tm-i960.h. VxGDB specific
3945 startup; DECR_PC_AFTER_BREAK, and FRAME_CHAIN_VALID are here.
3947 * valarith.c (value_subscripted_rvalue): Avoid handling
3948 floats and doubles specially; it gave alignment errors. Lint.
3950 * valops.c (value_of_variable, value_of_this): Error if unknown
3953 * valprint.c (print_floating): Bcopy rather than pointer-deref,
3954 to avoid alignment problems.
3955 (value_print): Handle unknown value address.
3956 (cplus_val_print): Two args are ignored; remove them. Change caller.
3957 (val_print): Use unpack_long rather than pointer-deref.
3960 (unpack_long, unpack_double): Use bcopy rather than pointer-deref
3961 to avoid alignment problems.
3962 (value_being_returned): Error if return value unknown.
3963 (set_return_value): Add bogosity warning, FIXME. *
3965 * TODO: A woman's work is never done.
3967 * Makefile.dist: Distribute REMOTE_OBS into tconfig files.
3968 Separate INCLUDE_CFLAGS for use with lint. Add LINTFILES.
3969 Add ieee-float.o to OBS.
3970 * tconfig/{nindy960,vxworks68,vxworks960}: Include the desired
3971 REMOTE_OBS remote-interface files in the TDEPFILES and TM_FILE.
3972 * tconfig/i960: FIXME. Half-merge, produce warning if config'd.
3974 Changes to generalize the VxWorks RPC protocol slightly, to handle
3975 i960 as well as 68000.
3977 * vx-share/dbgRpcLib.h (VX_SOURCE_STEP): Add.
3978 * vx-share/reg.h: Produce i960 regs #ifdef I80960
3979 * vx-share/xdr_ptrace.c: Skip FPA registers if 960.
3980 * vx-share/xdr_rdb.h: Add SOURCE_STEP struct and xdr decl.
3981 * vx-share/xdr_rdb.c: Add xdr_SOURCE_STEP routine.
3982 * vx-share/xdr_regs.c: Add xdr_regs, xdr_fp_status, xdr_ext_fp
3983 for i960. Change xdr_vectors to xdr_opaques for 68k registers,
3984 so they will move in target byte order rather than network
3985 byte order (happens to be the same).
3987 Mon Feb 25 03:41:44 1991 John Gilmore (gnu at cygint.cygnus.com)
3989 * tm-convex.h (END_OF_TEXT_DEFAULT): Remove #if 0'd block.
3991 Sun Feb 24 00:55:53 1991 John Gilmore (gnu at cygint.cygnus.com)
3994 Add contribution lines to various files, showing where they
3997 * breakpoint.c (break_insn, check_break_insn_size,
3998 read_memory_nobpt): Remove to mem-break.c.
4000 * xm-*.h, param-no-tm.h, tm-29k.h, valprint.c: Change BYTE_ORDER to
4003 * tm-29k.h (STAB_REG_TO_REGNUM): Warn user if symbol table
4004 entry has bad register number. This change is not
4005 tested in this release, FIXME.
4007 * frame.h: Eliminate Frame_unknown in favor of a simple zero.
4010 * value.h: Force value's contents field to be aligned to hold
4011 at least a double or a long long (if supported). This avoids
4012 doing bcopy's in and out of the contents field.
4014 (step_1): Avoid coredump under obscure circumstances when we
4017 * symtab.h (misc_info): Add field to misc function vector for
4018 any kind of cached information the target code desires. AMD
4019 29000 uses this to avoid repeating examine_function_prologue's.
4021 * coffread.c: Lint. Remove static symfile, read_section_header.
4022 core.c (have_core_file_p): Lint: remove.
4023 expprint.c (print_subexp): Lint.
4024 infptrace.c, valops.c, valprint.c: lint.
4026 Roll in changes from vxgdb-5.0.1:
4028 * symtab.h: Comment byte order of each address class. Add
4029 LOC_LOCAL_ARG for frame-relative args (960).
4030 expread.y: Use LOC_LOCAL_ARG where LOC_ARG is used.
4031 symtab.c, symmisc.c: ditto.
4033 * infrun.c (init_wait_for_inferior): Clear stop_signal.
4035 * remote.c (remote_resume): Error if resume with a signal.
4037 * symfile.c (prim_record_misc_function): Clear misc_info.
4038 (fill_in_vptr_fieldno): Check stub type of arg.
4040 * valops.c (value_cast): Avoid looking up names of types whose
4041 name we don't know, to prevent coredump. Sun CC produces typedef
4042 rtx and the name of *rtx is zero...
4044 Mon Feb 18 21:16:25 1991 John Gilmore (gnu at cygint.cygnus.com)
4046 Roll in changes from final AMD 29000 port (Tiemann).
4048 tconfig/am29k: Add COFF_ENCAPSULATE and TARGET=TARGET_AM29K
4049 for ../include/a.out.encap.h. This might not work now that BFD
4050 is separately compiled. Instead, BFD support for encap will have
4051 to translate machine type 29k into the right COFF_MAGIC.
4053 * infcmd.c: Remove references to inferior_pid that aren't used
4054 in actual ptrace calls; use target_has_execution, etc.
4055 (have_inferior_p): Remove function.
4056 (program_info): Print target info rather than "process number";
4057 avoid gratuitous messages unless from_tty.
4058 (run_stack_dummy, finish_command): Set proceed_to_finish.
4059 infrun.c: Remove inferior_pid refs. Decl & init proceed_to_finish.
4060 main.c: Lint. Lose have_inferior_p().
4061 inferior.h (have_inferior_p): Remove, lint.
4062 (proceed_to_finish): Add flag to ask that all regs be saved
4063 by normal_stop, for the few commands that need it, speeding up
4064 serial I/O. Add comments to stop_registers.
4066 * remote-eb.c: Remove newline from breakpoint message we grep
4067 for. Never time out when running the user program.
4071 Wed Feb 13 15:34:40 1991 John Gilmore (gnu at cygint.cygnus.com)
4073 Roll in changes from vxgdb-5.0.1:
4075 * dbxread.c (read_dbx_symtab): If we encounter a "FORTRAN COMMON"
4076 symbol in its raw form, we are processing an unlinked ".o" file.
4077 See if the target environment has assigned it an address, using
4078 target_lookup_symbol (VxWorks does), and enter it into the symtab
4081 * tm-vxworks.h (FRAME_CHAIN, FRAME_CHAIN_VALID): Override usual
4082 68k versions for a simpler version that assumes zero FP at bottom.
4083 Fixes bug of truncated stack reports.
4085 * target.h (target_lookup_symbol): Define this routine's args
4086 and result, finally.
4088 * target.c (nosymbol): Default routine for target_lookup_symbol.
4089 (target_default): Default lookup_symbol and call_function too.
4090 (files_info): Only print has_all_memory warning if a non-dummy
4093 * remote-vx.c (vx_read_register, vx_convert_to_virtual,
4094 vx_convert_from_virtual): If target does not have floating point,
4095 zero register "values", and avoid doing cross-net conversions.
4096 (vx_lookup_symbol): Rename net_lookup_symbol, add to vectors.
4097 (vx_open): Rearrange code that attaches to target and reads
4098 symbols for all loaded modules, to work if some of the modules
4099 are not accessible. Add symbol_stub() and add_symbol_stub()
4100 as callbacks from catch_errors(). Allow connect attempt to be
4101 interrupted painlessly with ^C (FIXME, there are still some bugs
4102 if the interrupt happens during symbol reading.). Print
4103 final message with puts_filtered, since symbol messages are
4108 * main.c (catch_errors): Only print errstring if non-null.
4109 (command_loop): Avoid an ioctl per command to test ISATTY.
4111 * remote-vx.c (net_load): make static; avoid sophomoric msg.
4112 (vx_xfer_memory): Return correct result!
4113 (vx_files_info): Indicate whether target has float or not.
4114 (vx_lookup_symbol): Complain, not error, if target gone.
4115 (vx_open): Print "Connected" msg before disabling immediate-quit.
4116 [FIXME: lookup_symbol and vx_open changes need testing.]
4118 target.c, remote-eb.c, inftarg.c, am29k-opcode.h, target.h,
4119 tm-29k.h, tmm-vxworks68.h, symfile.c, gdb-int.texinfo: Add
4120 contributor lines and update copyrights to 1991.
4122 Changes from an attempted H-PUX host port:
4124 * infptrace.c (PT_ATTACH, PT_DETACH): Handle HP/UX, which
4125 defines PT_ATTACH and PT_DETACH but not PT_KILL.
4126 * remote-eb.c (eb_open): Misplaced endif kills sysv H/PUX.
4127 * remote-vx.c: include <sys/time.h> for HPUX.
4128 * hp300hpux-xdep.c (fetch_core_registers): Rewrite old
4129 "core_file_command" routine to BFD regime. May not work yet.
4131 Attempted port of "gdb-3.4 Van Jacobson xgdb" to modern gdb.
4133 * xgdb.c: Replace X10 version with some VJ version.
4134 (FIXME: Its copyright assignment is not on record.)
4135 * xgdb.c: Update include files to X11R4 (Xaw crud).
4136 (xgdb_display_source, create_text_widget): fix call to
4137 get_filename_and_charpos. Rewack source window stuff for X11R4
4138 (gleaned from include files, and "nm's" of binary libraries, since
4139 I had no doc available).
4140 (append_selection, append_selection_word): Disable with FIXME
4141 since R4 changed interface here.
4142 (create_buttons): Add back the old set of buttons.
4143 (xgdb_create_window): Fix call to XtInitialize (&argc not argc).
4145 * Makefile.dist (xgdb, xgdb-init.c): Update for X11R4 on Suns.
4146 Roll VERSION to 3.94 (not yet final though).
4148 Sat Feb 9 09:46:25 1991 John Gilmore (gnu at cygint.cygnus.com)
4150 * obstack.h (obstack_ptr_grow, obstack_ptr_grow_fast,
4151 obstack_int_grow, obstack_int_grow_fast): Eliminate
4152 cast on left of assignment, which gives MIPS cc fits and is
4155 * sparc-pinsn.c (print_insn): Eliminate 'set' test, subsumed by
4156 F_ALIAS. Use printf, not fprintf, when not passing a file
4158 (compare_opcodes): Check that identical instructions have
4159 identical opcodes, complain otherwise.
4161 * sparc-opcode.h (st %fsr): Fix opcode "lose" mask. This
4162 was reported by Roland McGrath.
4163 (unimp): Only match if exactly zero instruction. (Roland)
4164 (branches and traps): Generate all variations of these
4165 instructions with macros, based on a single call that defines
4166 each condition name and its binary representation.
4167 (set): Turn on alias bit, to avoid test in sparc-pinsn.c.
4169 * valprint.c (val_print_fields): Take, and use, format parameter.
4170 This means that "p/x struct" again prints the elements in the
4171 desired format. Changed callers.
4173 * stack.c (frame_info): Use filtered output, and indicate wrap
4174 points. Remove kludgy formatting designed to avoid line wrap.
4176 * utils.c (wrap_here): If the line is already full (because
4177 we had printed a long indent or long wrapped string), do an
4178 immediate newline-and-indent.
4180 * m68k-pinsn.c (print_insn_arg): Bugfix from
4181 ntmtv!thompson@ames.arc.nasa.gov (Mike Thompson): 'bkpt #0'
4182 instruction is incorrectly disassembled as bkpt #8.
4184 * dbxread.c (end_psymtab): Bugfix from Peter Schauer
4185 <pesrem@regent.e-technik.tu-muenchen.de>: If you want to set a
4186 breakpoint in a *.y file gdb will say Reading in symbols for *.y...
4187 and then will dump core (sometimes). I traced it back to an
4188 uninitialized symfile_name in psymtab_to_symtab.
4189 (const_vol_complaint): Add quotes to message.
4190 (define_symbol): Only believe line number if gcc_compiled.
4191 Avoid allocating symbol if we will not return it.
4193 Add target strata support so that newly established targets go
4194 into their right place in the target stack (e.g. a new exec file
4195 doesn't wipe out the ability to access the running process).
4197 * target.h, core.c, exec.c, inftarg.c, remote-eb.c,
4198 remote-nindy.c, remote-vx.c, remote.c, target.c: Add to_stratum
4199 and initialize it properly in all the targets.
4201 * target.h: Document strata. Change return type of push_target.
4203 * target.c (nomemory): new function for dummy memory access.
4204 (tcomplain): Rename complain, now also used in symfile.c.
4205 (push_target): Push targets within strata. New return value shows
4206 whether new target is on top of stack or not. Always keep dummy
4208 (target_files_info): Ignore dummy target.
4210 * core.c (core_open): Warn user, and skip accessing file, if the
4211 core target is not the topmost target in the stack.
4212 * remote-nindy.c (nindy_create_inferior): Avoid unpush_target, now
4215 * remote-vx.c: Remove vx_prepare_to_store from vxworks memory
4216 target_ops, it doesn't belong there since we have no regs there.
4217 Change name of target from machine => memory to clarify.
4219 Thu Feb 7 16:32:09 1991 John Gilmore (gnu at spiff.cygnus.com)
4221 * Freeze version 3.93 for release.
4223 * Makefile.dist: Handle vx-share and nindy-share subdirs
4224 properly when building gdb.tar.Z.
4226 * symtab.c: lint; add no_symtab_msg to consolidate the messages
4227 printed in various places, so I could change just one copy.
4229 * dbxread.c, coffread.c: Change references to bfd->iostream
4230 to cast to FILE *, now that BFD avoids needing types defined
4231 in other header files.
4233 Tue Feb 5 21:39:35 1991 John Gilmore (gnu at cygint.cygnus.com)
4235 * command.c, dbxread.c, expprint.c, infcmd.c, infptrace.c,
4236 infrun.c, printcmd.c, remote-nindy.c, source.c, sparc-tdep.c,
4237 sparc-xdep.c, symfile.h, symmisc.c, utils.c, valprint.c: Lint
4238 (actually gcc -Wall).
4240 * dbxread.c: Remove first_global_sym, last_global_sym, since
4241 they are never referenced.
4243 * defs.h (baud_rate): Declare.
4244 main.c: Define it, and add the -b option to set it.
4246 * gdb-int.texinfo: Add text on how to define a new host or target
4247 architecture, prompted by Per Bothner's questions about MIPS
4250 * gdb.texinfo: Document "complaints". Change doc of -q since
4251 gdb no longer prints the copyright and blurb if you specify a file
4252 name to be debugged (just like Emacs). Add doc for Nindy-specific
4253 command line flags for specifying target serial port and such.
4254 Update copyright to 1991.
4256 * gdbcore.h: Remove a large mass of now-useless crud, since BFD
4257 has taken over for us the job of ripping up executable files. The
4258 crud caused Per Bothner's port to not compile.
4260 * infrun.c (normal_stop): Avoid printing "Program exited
4261 normally" if we are in batch mode. This allows a GDB which
4262 executes a program on a target system, to behave like a Unix
4263 command (input from stdin, output to stdout, no extraneous
4266 * main.c (main): Allow additional machine-dependent command line
4267 options to be specified with the ADDITIONAL_OPTIONS,
4268 ADDITIONAL_OPTION_CASES, ADDITIONAL_OPTION_HELP, and
4269 ADDITIONAL_OPTION_HANDLER macros. Also allow machine-dependent
4270 processing to occur just before the main loop with
4271 BEFORE_MAIN_LOOP_HOOK.
4272 (main): If a "core file" argument is specified, and it is not a
4273 core file, try it as a process ID to attach.
4274 (symbol_completion_function): Attempt to cope with
4275 "show screen-" TAB, not very successfully. This needs more work,
4277 (batch_file): New function, returns whether we are reading
4278 commands from an interactive tty on stdin, or from somewhere else.
4279 Called by normal_stop since it doesn't get from_tty passed down
4280 to it like many commands do.
4282 * remote-nindy.c: Handle command line options for nindy
4284 (nindy_before_main_loop): Prompt user for tty name if they
4285 don't specify it before getting to the interactive command loop.
4287 * tm-i960.c: Add ADDITIONAL_OPTIONS, etc, to handle -O, -brk,
4288 and -r command line options. Also add hook before main loop
4289 to make it easy to specify a tty.
4291 * TODO: More things to do, one done.
4293 Mon Feb 4 23:57:39 1991 John Gilmore and Mike Tiemann (at cygint.cygnus.com)
4295 * dbxread.c: Make complaint() calls pass pointer, not struct.
4296 Add complaints about badly formatted C++ type information
4297 (const/volatile indicator, and parse errors resulting in
4298 error_type). Fix C++ virtual member fn comment.
4299 (read_struct_type): Avoid bumping pointer if we got a parse
4300 error; this prevents our walking beyond the end of a string.
4301 Terminate loop on null char as well as semicolon.
4302 (process_one_symbol): Fix the LBRAC fix so that it uses the
4303 last previous SLINE, FUN, or SO record's PC address. C++ debug
4304 symbols did not have SLINE records in a useful order compared
4305 to the LBRAC records.
4306 (define_symbol): Handle "catch" records.
4308 * symtab.c (check_stub_type): Added new complain
4309 `stub_noname_complain' and added a consistency check to
4310 keep the debugger from crashing when finishing from an
4311 exception frame. A real fix will be needed later.
4313 Sat Feb 2 10:43:05 1991 John Gilmore (gnu at cygint.cygnus.com)
4315 * infcmd.c (attach_command): Make global.
4317 * Makefile.dist (REMOTE_OBS): Make these compile by default,
4318 but make them easy to comment out. Perhaps later they should
4319 be enabled by what CPU you configure for? FIXME.
4320 (VERSION): Roll to 3.93.
4321 (pinsn.o): Remove rule for obsolete file.
4322 (dbxread.o,coffread.o,mipsread.o): Use ${srcdir} explicitly.
4324 Run down a problem that manifested by printing the wrong function
4325 name in stack traces of read_ofile_symtab. Turned out that the
4326 problem was the SunOS 4.1.1 (and previous) C compiler outputs
4327 the LBRAC symbol with an address in the *data* segment, which
4328 blew our binary search through the blocks.
4330 * dbxread.c: Use the complain() facility consistently to bitch
4331 about problems in the symbol file we are reading.
4332 (finish_block): Add code to check the nesting of the blocks;
4333 complain and Procrust them to fit if wrong.
4334 (make_blockvector): Check the order of the blocks, complain
4335 [but don't cope] if wrong.
4336 (process_one_symbol): ifndef SUN_FIXED_LBRAC_BUG, check LBRAC
4337 symbols to be sure their PC value is greater than the last SLINE
4338 (line number) symbol we've seen, complaining and adopting the
4339 SLINE PC value if wrong.
4341 * symfile.h (struct complaint, complaint_root, complain,
4342 clear_complaints): Add.
4343 * symfile.c (complain, complaint_root, clear_complaints): Add
4344 facility to deal with non-fatal complaints and to regularize their
4346 (symbol_file_add): Clear complaint counters to allow new complaints.
4347 (initialize_symfile): Add 'set complaints' and 'show complaints'.
4349 * dbxread.c (dbx_symfile_read): Remember the address and size
4350 of the string table for the main symbol file, so we won't read it
4352 (dbx_psymtab_to_symtab): Fix the check for main symbol file,
4353 to avoid reading the string table yet again. Lint.
4354 (throughout): Improve filtered output, including word wrap.
4355 (read_range_type): Improve Bothner's fix to handle other types too.
4357 * utils.c: Improve line wrap implementation. Handle unlimited
4358 width by making chars_per_line unsigned.
4359 (puts_filtered): New, easy, function.
4361 * defs.h (puts_filtered): add.
4363 * mipsread.c (compare_symbols, sort_symtab): Remove these fns,
4364 call the identical sort_symtab_syms() in symfile.c instead.
4366 * expread.y: Suggest the `file' command rather than `symbol-file'.
4368 * command.h (enum var_types): Add zinteger for seroable
4370 * command.c (do_setshow_command): Handle var_zinteger. Restructure
4371 nested if's into a switch.
4373 * breakpoint.c (bpstat_print): If bpstat "print" flag is not set,
4374 we did not stop because of a breakpoint (it must have been for
4375 some other reason, like a "stepi"), so don't print anything.
4377 * symtab.c: Include <sys/types.h> all the time. Now that BFD
4378 doesn't include <sys/types.h>, old SunOS's require it for
4381 Sat Feb 2 10:39:15 1991 Per Bothner (bothner@cs.wisc.edu)
4383 A test port of gdb-3.92.6 to the Sony NEWS.
4386 Don't normally link in remote- or vx stuff.
4387 Some of it doesn't compile, and it wastes space for 99% of the users.
4388 Remove reference to no-longer-used HAVE_VPRINTF.
4389 Fixed BFD_DEP typo to BFD_DIR.
4391 Fix cast in arg to bfd_h_getlong.
4392 Make char *prefix be const.
4393 Fix how certain range types are mapped into builtin unsigned int types.
4395 Remove 2 #includes. They cause errors (on Sony, at least),
4396 and aren't needed (they wern't in earlier versions).
4398 print_address_symbolic should never demangle labels
4399 (since it prints *assembler-level* labels).
4401 [This was superseded by the change to printcmd below.]
4404 Add some "volatile" return types to avoid warnings.
4405 If MISSING_VPRINTF add vprintf function and not just macro
4406 (since vprintf is used in printcmd.c).
4408 Unless __GNUC__, use obstack_grow instead of obstack_ptr_grow.
4409 (The latter isn't grokked by some PCC-based compilers.)
4411 [This change is in abeyance, we prefer to fix obstack_ptr_grow.]
4413 Make chunk size of dont_print_obstack 32*4 instead of default 4096.
4414 * nindy-share/coffstrip.c
4415 Added some forward declarations (otherwise, gcc complains
4416 about implicit extern redefined as static).
4418 Sun Jan 20 02:38:19 1991 John Gilmore (gnu at cygint.cygnus.com)
4420 Changes inspired by Per Bothner:
4421 * printcmd.c (print_address_symbolic): Take additional parameter
4422 specifying whether to demangle.
4423 (print_address): Pass in asm_demangle to control demangling.
4424 (print_address_demangle): New fn, takes explicit arg to control
4426 * utils.c: Add new vars demangle and asm_demangle, and let them
4428 (fputs_demangled): If !demangle, just print the argument.
4429 (fprint_symbol): If !demangle, just print raw symbol.
4430 * valprint.c (val_print): Call print_address_demangle rather than
4431 print_address, to cause demangling to depend on the global
4432 rather than assembler-level demangling setting.
4433 * WHATS.NEW, gdb.texinfo: Document.
4435 * main.c (show_command): Show all settings if no arg.
4436 (initialize_main): Make "info set" the same as naked "show".
4437 * command.c (cmd_show_list): Handle prefix commands in the
4438 list, and print the name of the setting as well as its English
4439 description and value.
4441 Allow gdb functions to specify where a line should wrap if it
4442 exceeds the size of a terminal line. Use it to make the output
4444 * utils.c (set_screen_width_command): New fn, mallocs a buffer
4445 of the right size when screen width changes.
4446 (set_screensize_command, screensize_info): Remove #if 0'd fns.
4447 (wrap_here): New fn, indicates a point in the output where we
4448 should wrap the line rather than just letting it overflow at a
4450 (fputs_filtered): Implement wrapping.
4451 (n_spaces): New fn, returns a pointer to N spaces.
4452 (print_spaces_filtered): Use n_spaces.
4453 * defs.h (n_spaces): Declare.
4454 * stack.c (print_frame_info): Wrap with 4-space indent after
4455 fn name and before filename and line number.
4456 * printcmd.c (print_frame_args): Wrap with 4-space indent
4457 before each argument name is printed.
4458 * valprint.c (value_print): Wrap with no indentation before
4460 (val_print_fields): Wrap with indentation relative to nesting
4461 level before each field name.
4462 (val_print): Wrap with nesting indentation before array elements.
4463 * command.c (do_setshow_command): Avoid extra newlines,
4464 wrap with 4-space indent around values printed, end with period.
4465 * WHATS.NEW, gdb.texinfo, gdb-int.texinfo: Document.
4467 * breakpoint.c (breakpoint_1): Implement addressprint for
4468 "info breakpoints" display. Change file name and line number
4469 format to " at file:nnn" rather than " (file line nnn)".
4470 * gdb.texinfo: Document.
4473 Fri Jan 18 07:21:25 1991 John Gilmore (gnu at cygint.cygnus.com)
4475 Frozen for gdb-3.92.6 release.
4477 README, WHATS.NEW: Update for 3.92.6 release.
4479 tconfig/{altos, i386v, i386v32, m88k, umax}: Eliminate
4480 coffread.o from configs since it is now built by default.
4481 tconfig/{3b1, altosgas, arm, convex, hp300bsd, hp300hpux,
4482 i386v-g, i386v32-g, isi, merlin, news, news1000, np1, pn,
4483 pyramid, symmetry, vax, vxworks68}: Eliminate dbxread.o
4484 from configs since it is now built by default.
4486 Makefile.dist: Update for release 3.92.6. Handle files that
4487 have been moved to ../include, ../getopt, or ../bfd. Add
4488 saber.suppress and tests directory. Add config.status to
4489 the release (it will say "none").
4491 coredep.c: Minor formatting fixes.
4493 These changes were made in early December but only checked in now:
4494 * nindy-share/Onindy.c, nindy-share/coffstrip.c,
4495 nindy-share/nindy.c: lint
4496 * nindy-share/nindy.c (ninStopWhy): Don't byteswap the
4497 register values coming back from the target; we store values
4498 in target byte order everywhere.
4500 Wed Jan 16 19:01:37 1991 John Gilmore (gnu at cygint.cygnus.com)
4502 * am29k-opcode.h, am29k-pinsn.c: Add 29050 opcodes.
4504 * valprint.c (cplus_val_print, val_print_fields): New functions,
4505 which print C++ objects. They conspire to avoid printing a
4506 virtual base class more than once, following all the twists and
4507 turns of C++ virtual base rules.
4508 (val_print): Call the above rather than do it by hand.
4510 * symfile.c (symbol_file_add): Only reset symfile_mtime for main
4511 symbol file, not for added files like shared libs. This really
4512 needs to be generalized to a timestamp per file.
4514 * core.c (cleanup_core): Avoid coredump if no core file.
4516 * config.gdb: Accept -host or -target in place of +host or
4519 * coffread.c (find_linenos): Avoid desupported BFD interface
4520 to line numbers. We still read them manually rather than using
4521 BFD's "generic" features.
4523 * gdbrc.tex, threecol.tex: Add GDB reference card and its
4525 Makefile.dist: Add refcard to OTHERS list for creating tar files.
4527 * Makefile.dist: Eliminate use of $< in explicit targets.
4529 * readline/Makefile: Use $< rather than $*.c, which does not
4530 include the VPATH in GNU Make.
4532 * tconfig/i960-bout, tconfig/i960-coff: These are identical
4533 copies of tconfig/i960, added for global configuration
4534 compatability. All i960 versions can read both coff and b.out.
4536 * tm-88k.h: Fix multiline macro that lacked \'s. Remove
4537 COFF_FORMAT and COFF_CHECK_X_ZEROES since these are now handled
4540 * TODO: Think of more things to do.
4542 Wed Jan 2 19:09:29 1991 John Gilmore (gnu at spiff.cygnus.com)
4544 tconfig/{am29k,i960,sun2*,sun3*,sun4*}: Eliminate config
4545 of sdb versus dbx debug symbols. Add kludge for 68881 80-bit to
4546 64-bit float conversion.
4548 tconfig/sun4, tconfig/sun3, xconfig/sun4, xconfig/sun3: Make
4549 equivalent to sun?os4 so global config works.
4551 Wed Jan 2 18:20:51 1991 John Gilmore (gnu at spiff.cygnus.com)
4553 Fix from Eberhard Mattes <mattes@azu.informatik.uni-stuttgart.de>
4555 * main.c: Only declare linesize once; declare pagesize not at
4556 all, since it is never used.
4557 (main): Clear newly allocated line before it is used.
4559 Fri Dec 28 00:13:42 1990 John Gilmore (gnu at cygint)
4561 Further stabilization for the Intel 960.
4563 * Makefile.dist: Parameterize the location of the "include"
4564 and "bfd" directories, as well as "getopt". Add symfile.c.
4565 Link in both dbxread and coffread. Fix up "make depend" to
4566 rewack the locations of include, bfd, and getopt in its output.
4568 * README: Document moving include files, improve some of
4571 * coffread.c: Move common code out to symfile.c. Change
4572 symbol_file_command style interface to use new *_symfile_init
4573 and *_symfile_read interface under BFD. Use BFD internal
4574 info to locate line table, symbols, etc.
4576 * core.c (core_fetch_registers): Rename to get_core_registers
4577 to avoid confusion with fetch_core_registers.
4578 (register_addr): Move to coredep.c, which is already machine
4579 dependent. This leaves core.c pretty clean of dependencies.
4581 * coredep.c (register_addr): Accept this routine from core.c.
4583 * dbxread.c: Move common code (with coffread.c, etc) into new
4584 symfile.c. Each psymtab now contains a pointer to the
4585 format-dependent function that knows how to read it in. Make
4587 (dbx_psymtab_to_symtab): Renamed from psymtab_to_symtab_2.
4588 (process_one_symbol): Add code to complain about a "compiler bug
4589 we muzzle here", if we actually see it.
4591 * eval.c (evaluate_subexp): Insert missing "break" statements
4592 in code that determines whether a variable is an lvalue in
4593 memory, register, or whatever. I detected this via a compiler
4594 bug in which it *almost* mashed out the whole switch statement.
4596 * gdb-int.texinfo: Add minor sections on configuring gdb for
4597 release, and about the README file.
4599 * infcmd.c (registers_info): Fix formatting somewhat. Still
4600 not as pretty as before, but it handles byte swapping.
4602 * remote-nindy.c: If data cache routines are interrupted while
4603 waiting for the remote end, be sure that any uninitialized cache
4604 blocks are on the free list, not on the valid list!
4606 * symfile.h: Flesh out this header file with all the various
4607 routines and variables that have been merged in from dbxread.c
4608 coffread.c, and symtab.c to symfile.c.
4610 * symfile.c: New file, containing code common to dbxread.c,
4611 coffread.c, and some code from symtab.c. All generic code for
4612 reading symbol files should be in here now.
4613 (unrecord_misc_function): Remove unused function.
4615 * symtab.h: Remove file-reading things to symfile.h.
4617 * symtab.c: Remove file-reading things to symfile.c.
4619 * tm-i960.h: Fix FRAME_CHAIN types; define PRINT_RANDOM_SIGNAL
4620 to decode i960 fault types.
4622 * target.h, remote.c, remote-eb.c, remote-vx.c, remote-nindy.c,
4623 target.c: Change type of the "resume" function from int to void,
4624 since its result was never used.
4626 Sat Dec 22 02:51:40 1990 John Gilmore (gnu at cygint)
4628 * main.c: Replace "stupid" with "caution"; you now "set caution
4631 * printcmd.c (print_scalar_formatted): Fix typo in 'g' format
4633 * infcmd.c (do_registers_info): Call val_print to deal with the
4634 byte order of the registers being printed. FIXME, this makes
4635 the formatting of the output uglier.
4637 * infcmd.c (wait_for_inferior): If PRINT_RANDOM_SIGNAL is
4638 defined, call it for signals the debugger doesn't itself use.
4639 The i960 uses this for more detailed fault information.
4641 * remote.c (remote_open): If arg is null, print help rather than
4644 * sparc-xdep.c (register_valid): Avoid declaring size, since
4645 various modules will think of various sizes depending on the
4646 architecture of their tm-file. FIXME, we need protection against
4647 actually entering one of those modules, which would clobber
4648 storage if not for the target architecture compiled into gdb.
4650 * stack.c (up_command, down_command): Always print the frame
4652 (up_silently_command, down_silently_command): New commands
4655 * i960-pinsn.c (reg), i960-tdep.c: Lint.
4657 * i960-tdep.c (i960_frame_chain_valid): Lookup_symbol now takes
4658 more parameters than it used to.
4660 * findvar.c (registers): Increase slop to 256 bytes, which should
4661 protect us against even most RISC machines with large register
4663 (locate_var_value): Move declaration inside related ifdef.
4665 * remote-nindy.c (): Use TIOCSETN rather than TIOCSETP
4666 throughout, to avoid throwing away buffered input from the board.
4667 (nindy_wait): Supply_register takes addr_of_value, not value.
4668 (i960_print_fault): Renamed from i80960_fault.
4669 (nindy_fetch_registers): Avoid have_regs stuff, just get them.
4670 (nindy_store_registers): Avoid regs_changed stuff, just stuff
4672 (nindy_create_inferior): Don't bother to write PC_REGNUM since
4673 we can set the PC in the call to proceed(). Unpush nindy_ops
4674 before pushing it on top, to avoid message to user. Eliminate
4675 commentary from Unix machines that just misleads here.
4676 (reset_command): Fix error message to suggest target command.
4678 Wed Dec 19 11:03:56 1990 John Gilmore (gnu at cygint)
4680 Release 3.92.5 as frozen.
4682 Stabilize the merged release...with help from lint, Saber C,
4685 Everywhere: Add include files needed to declare return types
4686 of functions called.
4688 * gdb.texinfo: Roland Pesch is documenting gdb, glory be!
4690 * breakpoint.h: Add undeclared breakpoint functions, and some
4691 functions for display handling since I couldn't think of a better
4694 * breakpoint.c (insert_breakpoints): Make code for disabling
4695 shared library bkpts more likely to work. It's used when we
4696 rerun a program and stop before the shared library has been
4698 (breakpoint_cond_eval, bpstat_stop_status): Pass arg as int,
4699 cast from pointer, so it squeezes through catch_errors.
4700 (bpstat_stop_status): Fix logic broken some time ago. We now
4701 always create a bpstat if the stop address matches a breakpoint,
4702 even if we don't stop there -- just like the old code used to do
4703 before I got my fingers into it (sigh).
4704 (breakpoint_1): Print "ignore count" after "stop only if"
4705 condition, since that's how it actually works.
4706 (mention): Handle watchpoints as well as breakpoints.
4707 (watch_command): use set_raw_breakpoint and mention to do most
4708 of the work (and initialize all the fields!). Only pass one
4709 arg to parse_c_expression, since that's all it takes.
4711 * command.c (not_just_help_class_command): Rename arg to args
4712 since we ignore "unused argument" warnings on vars named "args".
4713 inflow.c (child_terminal_info): ditto.
4714 infptrace.c (kill_inferior): ditto
4715 main.c (catch_errors, version_info, quit_command, pwd_command,
4716 source_command, dump_me_command, editing_info,
4717 set_history_size_command, set_history, show_history,
4719 stack.c (locals_info): ditto
4720 target.c (target_files_info): ditto
4721 valprint.c (set_input_radix, set_output_radix): ditto
4723 * core.c: Remove old variables for handling core and exec file
4724 sections (data_start, data_end, stack_start, stack_end,
4725 reg_stack_start, reg_stack_end, reg_stack_offset, text_start,
4726 text_end, exec_data_start, exec_data_end, text_offset,
4727 exec_data_offset, data_offset, stack_offset). They're
4728 superseded the more general build_section_table and
4730 (get_exec_file): Mention the `file' command.
4731 (read_memory_check): Rename to memory_error, and only call it
4732 in the case of an actual error.
4733 (read_memory, write_memory): call memory_error.
4734 (core_fetch_registers): Register section name is ".reg".
4736 coredep.c: Remove a bunch of crud now that all this file does
4737 is pull the registers out of a core file.
4738 (fetch_core_registers): Rewrite to actually work, I hope.
4740 dbxread.c: Use a.out.gnu.h, not system a.out, now.
4741 Replace index() with strchr(). Remove all the pre-BFD macro
4742 definitions for accessing the symbol file.
4743 (struct dbx_symfile_info): Encapsulate the information that
4744 dbx_symfile_init needs to pass to dbx_symfile_read in this
4747 (dbx_new_init, dbx_symfile_init, dbx_symfile_read,
4748 dbx_symfile_discard): Rearrange symbol file reading to divide
4749 the format-specific part from the format-independent part,
4750 leaving the format-independent part such as file name expansion
4751 and opening in symtab.c. This replaces
4752 partial_symbol_file_open and partial_symbol_file_read.
4753 Symbol_file_read, add_file, add_file_target_command,
4754 add_file_addr_command move to symtab.c. Pass an explicit
4755 "mainline" flag for when reading the main symbol table, rather
4756 than relying on the offset address to be zero or nonzero.
4758 (dbx_symfile_read): Don't allow void *'s to be printed as
4760 (SWAP_SYMBOL): Use bfd routines to byte-swap the symbols.
4761 (ADD_PSYMBOL_TO_LIST): Make the "function call rather than
4762 macro" debug version really work.
4763 (read_dbx_symtab): Remove unref'd parameter inclink.
4764 Avoid swapping N_SLINE symbols, for speed.
4765 Merge N_TEXT!N_EXT case with the other external symbol
4766 definitions' case. Add comments.
4767 (start_psymtab): Allocate the symfile name in the psymtab on
4768 the psymbol_obstack, rather than using the caller's storage.
4769 (end_psymtab): Only allocate a dependencies list if there are
4771 (psymtab_to_symtab_2): Use BFD when reopening file to read
4772 its symbols for real.
4773 (read_struct_type): Add FIXME comments where it needs work
4775 (read_huge_number): Add FIXME about overflows.
4776 (read_range_type): Add FIXME about comparing a long to 1<<32.
4778 * coffread.c: Minor changes to move things closer to the new
4779 regime with symtab.c and dbxread.c Major work is still needed
4782 * exec.c (exec_file_command): Remove old variables (see core.c
4784 (xfer_memory): If memory transfer is right at the end of a
4785 section, don't lose.
4787 * findvar.c (get_saved_register): If value is in a real
4788 register, LVAL is lval_register, not lval_memory.
4790 frame.h: Declare print_sel_frame and record_selected_frame.
4792 gdb-int.texinfo: New file, for GDB internals documentation.
4793 Very simple, unformatted doc of cleanups is there for now.
4795 gdbcore.h: Remove obsolete variables that described a.out
4796 section addresses and offsets. (See core.c above.)
4797 Declare fetch_core_registers and registers_fetched.
4799 getopt.c: Declare char *alloca(); even on SPARC.
4801 infcmd.c (run_command): Call target_kill rather than
4803 (step_command, next_command, stepi_command, nexti_command):
4804 Declare from_tty parameter even though we don't use it.
4805 (run_stack_dummy): argument BUFFER is a char array, not
4806 a pointer to REGISTER_TYPE.
4807 (finish_command): using_struct_return needed a value *,
4808 not a struct symbol *.
4810 * infptrace.c (child_xfer_memory): To avoid dependency on
4811 where sections are in memory, try PT_WRITE_D and if that fails,
4812 try PT_WRITE_I. Most Unixes don't care which you use.
4814 * infrun.c (step_resume_break_shadow): Change to array to
4815 match other breakpoint shadow storage.
4816 (clear_proceed_status): Pass address of bpstat to
4817 bpstat_clear, not the bpstat itself.
4818 (child_create_inferior): FIXME comment about if the child
4820 (start_inferior): Remove old function.
4821 (child_open): Use target_kill rather than kill_inferior.
4822 (wait_for_inferior): Ditto.
4823 (insert_step_breakpoint, remote_step_breakpoint): Use
4824 new step_resume_break_shadow.
4826 * inftarg.c (child_wait): If all child processes die,
4827 pretend that the one being waited for exited with signal 42.
4829 * main.c (command_line_input): When scanning for comments,
4830 don't coredump on unclosed quotes.
4831 (quit_command): Use target_kill rther than kill_inferior.
4832 (_initialize_main): Rename class_user from "user" to
4835 * printcmd.c (print_command_1): Initialize "fmt" if no format
4836 is specified by the user.

4842 * remote-eb.c (eb_open): Avoid coredump on no argument.
4844 * remote-nindy.c: Bring out of Intel environment into new
4845 target environment. Remove all conditional compilation on
4846 I80960. Massive hacking throughout.
4847 (nindy_xfer_inferior_memory): New routine stolen from
4849 (nindy_create_inferior): New routine pieced together, probably
4850 not quite working yet.
4851 (nindy_ops): New target_ops struct for nindy.
4853 * remote-vx.c: Use write_memory rather than target_write_memory
4854 to get error checking.
4855 (vx_add_file_command, vx_open): Use symbol_file_add rather than
4857 (vx_create_inferior): Use target_terminal_ours...
4859 * signame.c (_initialize_signame): Always initialize, since
4860 we need the table for things other than psignal.
4862 * solib.c (solib_add): Use symbol_file_add, not add_file.
4863 (solib_address): Return boolean result rather than struct
4864 pointer which nobody else knows the type of.
4866 * sparc-tdep.c, valops.c: Use write_memory rather than
4867 target_write_memory, to get error checking.
4869 * stack.c (locals_info, catch_info, args_info,
4870 get_selected_block, frame_command, up_command): Use
4871 target_has_stack, rather than have_inferior_p or
4874 * sun3-xdep.c (fetch_core_registers): Rewrite for new BFD regime.
4876 * symfile.h: New file, defining the interface between the
4877 generic and object-file-specific symbol reading code.
4879 * symtab.c: Move generic symbol-reading interface to symtab.c,
4880 from dbxread.c, coffread.c, mipsread.c, etc. Add symtab_fns
4881 table to map BFD targets to symbol-reading modules in GDB.
4882 Change index to strchr.
4883 (lookup_struct_elt_type): Use error() rather than hand-made
4884 simulations thereof.
4885 (lookup_partial_symbol): Speedup slightly when length == 0.
4886 (symbol_file_add): New function.
4887 (symbol_file_command): Call it.
4888 (symfile_open, symfile_init): New function.
4889 (add_file_target_command, add_file_addr_command): moved from
4892 * target.c (target_command): use target_kill.
4894 * target.h (target_files_info): Don't declare, never called
4897 * tm-sun2.h, tm-sun3.h (STACK_END_ADDR): Use system include
4898 files to determine stack end address.
4900 * valarith.c (value_x_binop, value_x_unop): Change error message
4901 to be more useful. Pass proper argument to value_struct_elt.
4903 * valops.c (value_assign): FIXME comment that long long
4904 bitfields will break here.
4906 * Makefile.dist: Add symfile.h, remote-nindy.c, remote-eb.c.
4907 Update `make saber_gdb' to work better.
4909 * TODO: A woman's work is never done.
4911 * cplus-dem.c, environ.c, inferior.h, infrun.c, inftarg.c,
4912 main.c, obstack.c, printcmd.c, remote-eb.c, remote-nindy.c,
4913 remote-vx.c, remote.c, solib.c, source.c, sparc-pinsn.c,
4914 sparc-tdep.c, sparc-xdep.c, symmisc.c, symtab.c, symtab.h
4915 target.c, terminal.h, tm-sparc.h, tm-sunos.h, utils.c,
4916 valops.c, valprint.c, exec.c: Lint.
4919 Wed Dec 12 23:44:15 1990 John Gilmore (gnu at cygnus.com)
4921 Continuing Intel 960 port merge of GDB.
4923 * Makefile.dist: Merge i960 "nindy-share" files. Rename
4924 malloc.h to gmalloc.h to avoid name conflicts in /usr/include.
4925 Don't ship gdb.dvi in tar file. Link gdb with init.o, not init.c.
4926 Wack over "make depend" so it handles files in subdirectories
4927 vx-share, nindy-share, bfd, and in the current directory.
4929 * blockframe.c (get_prev_frame_info): Remove fatal error
4930 if stack not defined.
4932 * core.c (core_open, core_detach): New functions that handle
4933 the old "core-file" command as "target core" and "detach" instead.
4934 (core_file_command): Call them.
4935 (core_xfer_memory): Use common routine xfer_memory.
4937 * dbxread.c: Include a.out.gnu.h, not system a.out.h.
4938 dbxread now uses bfd for everything but symbol reading itself.
4939 BFD internals are used to drag out the relevant file offsets.
4940 (partial_symbol_file_open): Change args all around for BFD.
4942 * symtab.c: Rename "value" to "val" everywhere, so we can
4944 (symbol_file_command): New command, moved from dbxread.c
4945 and coffread.c. It uses BFD to read the file, then vectors
4946 based on its type, to dbx or coff symbol readers.
4947 * symtab.h: Extern a few vars for symbol_file_command.
4949 * target.h: Breakpoint takes a char * save area, not a char **.
4951 * valprint.c (val_print): When unpacking bitfields, offset
4952 the address in gdb of the value, if it is declared with a shorter
4953 type. Remove the last "runtime kludge test" of host byte order.
4955 * utils.c: Remove old my_bfd_read routine.
4957 * stack.c (frame_info): Use target_has_stack. Print program counter
4958 register's actual name rather than "pc", since it's called the
4959 "ip" (instruction pointer) on the i960 (sigh).
4961 * target.c (target_command): Add command for selecting a target
4962 type and calling its open routine. This is used for initiating
4963 communication with a particular target, in a generic way.
4965 * tm-i960.h: Update for modern gdb. Remove semicolons from
4966 various macros. Handle reading struct return convention, and
4967 error-out attempts to return structs with the "return" command.
4968 Be sure gdb doesn't think we know how to call functions in the
4971 * i960-tdep.c: Rename FRAME_CHAIN_VALID and FRAME_FIND_SAVED_REGS
4972 to i960_xxx in lower case.
4973 (arg_address): Circumvent errors due to LOC_ARG_BLOCK
4974 not being defined yet.
4976 * remote.c (remote_open): Call start_remote to initialize
4977 wait_for_inferior during open.
4978 (remote_xfer_inferior_memory): Return length written rather
4981 * remote-vx.c (target_command -> vx_open): Use new generic
4983 * remote-eb.c, inftarg.c, exec.c: ditto.
4985 * infrun.c: Fix comments.
4986 (attach_program -> child_open): Use new generic target command.
4987 (wait_for_inferior): Clear saved register values before target_wait,
4988 so target_wait can set some of them if convenient.
4990 * infptrace.c (fetch_inferior_registers, store_inferior_registers):
4991 Return success indicator, not void.
4992 (child_xfer_memory): Avoid fetching initial word if we'll
4993 overwrite it anyway.
4995 * infcmd.c (attach_command): Use new generic target open routine.
4996 (_initialize_infcmd): Update doc on attach and detach commands.
4997 (do_registers_info): Merge in a byte-order problem as a FIXME
5000 * findvar.c (find_saved_register): Avoid problem in current frame.
5001 (read_relative_register): Ditto.
5002 (write_register): Convert byte order on the way out.
5004 * exec.c (file_command): Add.
5005 (add_to_section_table, exec_command): Use new bfd_map_over_sections.
5006 (xfer_memory): Common function between core_xfer_memory and
5008 (exec_xfer_memory): Use it.
5010 * pn-opcode.h: Document that a "PN" is a Gould PowerNode.
5012 * breakpoint.c, breakpoint.h, symtab.h, value.h, frame.h, utils.c,
5013 valops.c, stack.c, target.c, sparc-xdep.c, source.c, printcmd.c,
5014 infcmd.c, i960-pinsn.c, eval.c, defs.h: lint and gcc -Wall.
5016 Sun Dec 2 16:45:06 1990 John Gilmore (gnu at cygnus.com)
5018 Merge Intel 960 port of gdb, continuing...
5020 * dbxread.c (partial_symbol_file_open, partial_symbol_file_read,
5021 symbol_file_command): Pass from_tty arg to hush 'em up.
5023 * coffread.c (symbol_file_command): Avoid output if from_tty != 1.
5024 Add magic numbers for 960 COFF format.
5026 Fri Nov 30 09:18:20 1990 John Gilmore (gnu at cygnus.com)
5028 Merge Intel 960 port of gdb, from Intel "1.2" release.
5030 CHANGE_LOG entries from their port, which was based on
5033 Thu Sep 6 11:02:22 PDT 1990
5034 Remove temp file if download is interrupted.
5036 Wed Aug 1 09:08:33 PDT 1990
5037 Now uses binary protocol to talk to NINDY.
5038 Old hex protocol (NINDY 2.13 and older) supported with -O switch.
5039 Times out after 5 seconds when trying to talk to NINDY.
5041 Tue May 29 12:54:49 PDT 1990
5042 Added variable baud rate (-b switch).
5043 Source code reorganization.
5045 Thu Apr 26 11:09:55 PDT 1990
5046 More cleanup of batch mode; specifically, execute "-s", "-e", and
5047 "-se" switches as soon as they are encountered on the invocation line.
5049 Fri Apr 20 13:47:15 PDT 1990
5052 Thu Apr 19 09:54:28 PDT 1990
5053 Add 'reset' command.
5055 Wed Apr 18 09:48:07 PDT 1990
5056 After opening remote tty, wait for 1 second to go by without input
5057 from it before trying to talk to NINDY (fixes problems with the
5058 Heurikon HK80/V960E).
5060 Mon Apr 4 16:33:05 PDT 1990
5061 Some output was not being suppressed in 'batch' mode.
5063 Thu Mar 22 15:31:11 PST 1990
5064 Ask user if old symbol table should be deleted when new file is
5067 Allow user to run a program downloaded before gdb960 was brought up.
5069 Correct "exec-file" help message for i80960 context.
5071 Correct bug in calculating user space address: could occasionally
5072 corrupt user program.
5074 Make sure to zero low-order bits in rip's because of bug in 960CA
5075 A-step part: could cause operation faults when "next"ing across
5078 Correct bug that made it impossible to get source line numbers for
5079 code loaded at addresses higher than 0x7fffffff.
5081 Wed Jan 10 12:43:22 PST 1990
5082 Open remote tty for exclusive use.
5084 Fri Jan 5 12:14:42 PST 1990
5085 Correct disassembly (CA manual was right after all):
5086 opcode for sysctl is 0x659
5088 Mon Oct 23 12:03:04 PDT 1989
5089 Use G960BASE and G960BIN environment variables to find 'sx' utility.
5091 Mon Oct 16 14:15:09 PDT 1989
5092 "sfr0"-"sfr31" should have been named "sf0"-"sf31"
5094 Mon Oct 2 15:56:31 PDT 1989
5096 Added 960CA disassembly support.
5098 To simplify maintenance:
5099 - eliminated use of symblic links on pinsn.c: use i960-pinsn.c
5101 - eliminated opcode.h: incorporates tables into i960-pinsn.c
5102 - moved 960-specific routines from i960-pinsn.c to i960-md.c
5103 - made disassembly interface identical to that in gdmp960.
5107 Wed Nov 28 21:32:48 1990 John Gilmore (gnu at cygint)
5109 * target.h: Allow targets to stack. Add target_has_memory,
5110 _registers, etc. Restructure memory access and "info files"
5111 to walk the target stack.
5112 * exec.c, core.c, inftarg.c, remote.c, remote-vx.c, remote-eb.c,
5113 target.c: Change tables to match target.h.
5114 * inflow.c (child_mourn_inferior): pop child_ops.
5115 (generic_mourn_inferior): Use new has_stack flag.
5116 * infptrace.c (child_xfer_memory): New memory regime.
5117 * inftarg.c (child_files_info): New "info files" regime.
5118 * remote-eb.c: New memory regime, new info files.
5119 * remote-vx.c: New memory regime, new info files. Now use
5120 separate targets for VxWorks attachment to machine, and
5121 actually running a process under VxWorks, since one has
5122 stack & execution & regs and the other doesn't.
5123 * remote.c: New memory regime, new info files.
5124 * sparc-xdep.c (fetch_core-registers): New memory regime.
5125 * target.c: New routines and support for stacked targets,
5126 new memory regime, new info files regime.
5129 Generalize section handling for an arbitrary number of sections,
5130 including use of the new BFD (binary file) library.
5131 * gdbcore.h: Add struct section_table.
5132 * exec.c (build_section_table): Iterate all sections and
5133 record what gdb needs to know about them.
5134 (exec_command): Use it.
5135 (exec_xfer_memory): Use the table.
5136 (exec_files_info): Print the table.
5137 * core.c (core_file_command, core_xfer_memory, core_files_info):
5139 * source.c (find_source_lines): Use bfd_get_mtime.
5140 * dbxread.c: Quick changes to make it compile with new BFD.
5141 * utils.c (error): Avoid using bfd_error in generic routines.
5143 * core.c (core_fetch_registers): Get from the ".regs" section of
5145 * sparc-xdep.c (fetch_core_registers): Use the .regs info.
5147 * inferior.h (attach_flag): Export.
5148 * infcmd.c (run_command): use new target_create_inferior.
5149 * infrun.c (child_create_inferior): Don't return result.
5150 * Makefile.dist (VERSION): 3.91.4.
5152 Fri Nov 23 28:15:38 1990 John Gilmore (gnu at cygint)
5154 * breakpoint.c (bpstat_num): Handle breakpoints which have
5155 since been deleted, such as temporary breakpoints.
5156 infcmd.c (program_info): ditto.
5158 * core.c (core_file_command): Display the frame where the core
5163 * remote-vx.c (target_command): Merge in target command from
5164 targ-vx.c. A few other cleanups.
5166 * TODO, Projects: Lots more stuff to do...
5168 Fri Nov 23 18:15:38 1990 John Gilmore (gnu at cygint)
5170 Massive changes to wall off the remote-debugging interface
5171 behind a function vector. The port to handle VxWorks targets
5172 is also part of this.
5174 All files: Replace references to renamed functions,
5175 remove references to remote_debugging, remove references to
5176 have_include_file, have_core_file in favor of target_has_stack,
5177 target_has_memory, etc.
5179 * Modularize the breakpoint interface.
5180 breakpoint.h (BREAKPOINT_MAX): New define sets max length of
5181 a breakpoint instruction.
5182 breakpoint.c: struct breakpoint's shadow_contents now sized as
5184 (insert_breakpoints): Vector to target to install breakpoints.
5185 (remove_breakpoints): Vector to target here too.
5186 Remove REMOTE_SA_SPARC kludges and other remote_debugging.
5187 sparc-tdep.c (single_step): Use new breakpoint interface for
5188 the single-step breakpoints.
5189 mem-break.c (memory_insert_breakpoint, memory_remove_breakpoint):
5190 New file, contains routines to insert and remove breakpoints by
5191 reading out the old contents and later replacing them. This is
5192 how ptrace breakpoints work, and many remote systems as well.
5194 * tm-vxworks68.h: New config file, overrides a few things for
5195 Wind River's preferences.
5197 * target.h: New file, for transfer vector used to talk to the
5198 inferior (child, attached, core, exec, remote, etc). All accesses
5199 to the thing being debugged should come through these vectors.
5200 target.c: New file, routines to handle transfer vector.
5201 (various files): Add transfer vectors XXX_ops for the various
5202 targets and pseudo-targets (core files, etc) we support.
5204 * breakpoint.c (bpstat_stop_status): Further explorations of
5205 watchpoints and why things don't work all the time.
5206 (bpstat_alloc): New fn to allocate a bpstat and chain it.
5208 * config.gdb: Only add "source ${srcdir}/.gdbinit" to
5209 the local gdbinit if it doesn't already have it.
5211 * core.c (core_ops): add and install.
5212 Allow core debugging without exec file.
5214 * dbxread.c (free_and_init_header_files): Merge two fns.
5215 (end_symtab): Free named symbol table when a new version comes in.
5216 (read_dbx_symtab): Relocate all kinds of symbols with base
5217 address. First step toward handling different text, data, bss
5219 (add_file_addr_command): Renamed add_file_command.
5220 (add_file_command): Vector to remote handler.
5221 Add "load" as an alias for "add-file" command.
5223 * defs.h: Allow "volatile" to be used in non-ANSI; use it for
5224 non-returning functions.
5226 * exec.c: Add exec_ops, and push it as a target when an exec
5229 * infcmd.c (run_command): Pass executable file name and arg list
5230 separately when starting an inferior. Permit "run" when no exec
5231 file is specified, for VxWorks.
5232 (detach_command): Move to child_detach in inftarg.c.
5234 * inftarg.c: New file. Unix-child-specific routines, and the
5235 child_ops structure.
5237 * inferior.h (registers): Export "registers" as the way for
5238 target dependent register handlers to find gdb's local copy of
5239 the registers. Rename "stop_after_attach" to "stop_soon_quietly"
5240 since it is now used by places that want wait_for_inferior to
5241 handle the grunge but want to see every trap from the inferior.
5243 * inflow.c (create_inferior): Pull out, and merge into infrun.c.
5244 Eliminate remote_debugging hooks in terminal handling.
5246 * infrun.c: Replace start_inferior with child_create_inferior.
5247 Move all the hair of Unix shells and ptrace idiosyncracies into
5248 child_create_inferior, so remote handlers don't have to deal.
5249 Remove running_in_shell. Rename stop_after_attach to
5250 stop_soon_quietly, and use it in a few other places where we want
5251 to just call wait_for_inferior and get control back on the first
5252 trap. trap_expected now never takes a value > 1.
5253 (init_wait_for_inferior): Initialize static vars when a new
5256 main.c (gdbinit): Add new hook for .gdbinit file name, let
5257 it be overridden by config files as GDBINIT_FILENAME.
5258 (DEFAULT_PROMPT): Add new hook for overriding (gdb) prompt.
5259 Both of these are used for VxWorks gdb.
5261 mcheck.c: rename include file "gmalloc.c" to avoid problems
5262 with system include file "malloc.c".
5264 param-no-tm.h: New include file, same as param.h but does not
5265 include the default "tm.h" file. This is used in files where
5266 the target is known, e.g. remote-eb.c or sparc-xdep.c.
5268 param.h: Now just a shell that includes tm.h and param-no-tm.h.
5270 remote-vx.c: New file, VxWorks remote debugging support. Uses
5271 RPC routines that are shared with the target system, in directory
5274 remote.c: Vectorize remote interface.
5276 source.c: Globalize source_path, and make an alias "l" for "list"
5277 since we now have the "load" command.
5279 sparc-xdep.c: Use new param-no-tm.h.
5281 symmisc.c (free_named_symtab): Add new function from Wind River.
5282 However, ifdef it out for now while we think about what it should
5285 tm-sun3.h, xm-sparc.h, xm-sun3.h, xm-symmetry.h: Move
5287 the xm- file, and change its name to CHILD_PREPARE_TO_STORE, since
5288 non-Unix-children handle this with their own code in the target
5291 Makefile.dist: Roll version to 3.92.3. Add vx-share stuff to
5292 source and target lists. Add vx-share to default list of include
5293 directories. Add new files to src and target lists: mem-break,
5294 target, inftarg, remote-eb, remote-vx, targ-vx. Be sure the
5295 ${srcdir} versions of munch and createtags are used.
5297 * valops.c (find_function_addr): Split out of call_function.
5298 (call_function_by_hand): Rename call_function; this function
5299 calls functions in the target by laboriously patching the target
5300 word-by-word with the right stack, args, regs, etc.
5303 Mon Nov 5 17:29:10 1990 John Gilmore (gnu at cygint)
5305 Handle AMD 29000 a bit better.
5307 * remote-eb.c (readchar): Mask received char log to make it readable.
5308 (remote_start): Pass arguments down to executing program.
5309 Make startaddr unsigned.
5310 infrun.c (start_inferior): Accept args, pass them to
5312 infcmd.c (run_command): Pass args down to start_inferior.
5314 * tconfig/am29k-aout, tconfig/am29k-coff: New files specifying
5315 the target object file format.
5316 tm-29k.h: Pay heed to COFF_ENCAPSULATE.
5318 * am29k-pinsn.c (print_insn): Print 0x on hex numbers in disassembly.
5319 am29k-tdep.c (examine_prologue): Better checking of function prefixes.
5321 Sun Oct 7 18:20:45 1990 John Gilmore (gnu at cygint)
5323 * Makefile.dist (VERSION): Roll version to 3.91.9 and freeze.
5324 * TODO: We did a few things, we have more to do though.
5326 * xm-sparc.h (CLEAR_DEFERRED_STORES): Define.
5327 * inflow.c (inferior_died): Clear deferred stores.
5329 * Debug problems with dummy frames and calls to the inferior.
5330 * tm-sparc.h (PUSH_DUMMY_FRAME, POP_FRAME): Move to sparc-tdep.c.
5331 * sparc-tdep.c (do_restore_insn): Simplify.
5332 (sparc_frame_find_saved_regs): Simplify and fix what we find.
5333 (sparc_push_dummy_frame): Simplify and fix what we push.
5334 (sparc_pop_frame): Slightly more hair here, deciding whether
5335 we are restoring a saved PC or returning to a return address in %i7.
5336 * sparc-xdep.c (read_inferior_registers): Debug if valid reg is read.
5338 * utils.c (xmalloc, xrealloc): Return type depends on __STDC__.
5339 * symtab.h (xmalloc): ditto, for obstack_chunk_alloc.
5340 * obstack.h (chunkfun): ditto.
5341 * defs.h (xmalloc, xrealloc): ditto
5343 * utils.c (quit): Grab the terminal from the child if necessary.
5345 * inflow.c (term_status_command): Rename to term_info, change
5348 * sparc-pinsn.c (print_insn): Disassembly prefers real instructions.
5349 (is_delayed_branch): Speed up.
5350 * sparc-opcode.h: Add ALIAS bit to aliases. Fix up opcode tables.
5351 Still missing some float ops, and needs testing.
5353 * Support for input and output radixes other than base 10
5354 * defs.h (input_radix, output_radix): Declare.
5355 * expread.y (yyparse, parse_number): Handle changes of input
5356 radix, and ambiguous names-or-numbers in radixes >10.
5357 * printcmd.c (print_scalar_formatted): Print formatted hex
5358 numbers in varying column widths.
5359 * valprint.c (val_print): Use output_format to print scalar ints.
5360 (set_input_radix, set_output_radix, set_radix): Create.
5361 (set_output_radix): Set output_format from output_radix.
5362 (_initialize_valprint): add `set radix' but leave the others off.
5364 * main.c (execute_command): Let stupid questions be turned off.
5365 (_initialize_main): Handle "set stupidity", etc.
5367 * main.c, inflow.c, inferior.h, frame.h, command.c, defs.h,
5368 sparc-pinsn.c, sparc-xdep.c, value.h, valops.c, values.c: Lint.
5370 Tue Oct 2 11:20:02 1990 John Gilmore (gnu at cygint)
5372 * TODO, Makefile.dist, ChangeLog: Freeze for 3.91.8 release.
5373 bfd stuff is still screwed up, but with some manual work, it
5376 * breakpoint.c (bpstat_do_actions): Start over if a command
5377 proceeds the inferior, since the inferior will have stopped and
5378 will need to have its new stop-actions taken care of.
5380 * dbxread.c (read_struct_type): Expression gives Sun3 4.0.3
5381 compiler fits, simplify it.
5383 * gdb.texinfo (directory command): Doc new dir command.
5384 source.c (directory_command): "dir" now puts things on the front
5385 of the path, moves dups up front, and handles multiple names
5386 on the command line, inserting each one in order. It also
5387 blows away cached line and full_filename info.
5389 * stack.c (backtrace_command): Skip "more stack frames follow"
5392 * Change #ifndef HAVE_VPRINTF to #define MISSING_VPRINTF in
5393 xm-convex.h, xm-hp300bsd.h, xm-isi.h, xm-merlin.h, xm-news.h,
5394 xm-np1.h, xm-pn.h, xm-pyr.h, xm-symmetry.h, xm-umax.h, xm-vax.h.
5395 The only odd one was Gould NP1, which had defined vprintf to
5398 * Merge Ted Goldstein <tedg@Eng.sun.com>'s changes for epoch.
5399 printcmd.c (print_command_1): Pass 'inspect' flag down as a global
5400 variable, inspect_it.
5401 valprint.c (print_string, val_print): Use the global inspect_it
5402 to indicate whether to print in Epoch style or normal style.
5404 Mon Oct 1 23:55:26 1990 John Gilmore (gnu at cygint)
5406 * printcmd.c (call_command): add an alias for the "print" command
5407 which runs expressions and doesn't print the result if void.
5408 (print_command_1): implement it.
5410 * command.c: Remove #if 0'd code. Initialize all the fields
5411 in add_cmd (). Rename do_nothing_command to
5412 not_just_help_class_command, and make it externally visible.
5413 command.h: add user_commands to struct.
5414 * main.c (define_command): Don't overload c->function with a char
5415 string as well as a function pointer.
5417 * eval.c (evaluate_subexp): Reinstall tiemann changes to
5418 calling convention of value_struct_elt () that got dropped in
5421 * tm-sparc.h (FRAME_FIND_SAVED_REGS): move to sparc-xdep.c.
5422 sparc-tdep.c (sparc_frame_find_saved_regs): ditto.
5424 * tm-sparc.h (POP_FRAME): replace some constants with defines.
5426 * sparc-xdep.c (store_inferior_registers): defer stores to regs
5427 until a good time (e.g. when we are about to run the child),
5428 saving ptrace calls.
5429 * infrun.c (proceed): handle DO_DEFERRED_STORES.
5430 * tm-sparc.h: define DO_DEFERRED_STORES.
5432 * sparc-xdep.c (store_inferior_registers): when storing float
5433 registers, don't store stack regs too. When storing the SP,
5434 however, DO store the stack regs too. This fixes a bug in which
5435 the dummy frame is not recognized when a call_function finishes,
5436 because its frame pointer (in the stack regs) was never
5438 (read_inferior_registers): Mark WIM and TBR and FPS and CPS valid
5439 even though we don't know how to read them from an inferior.
5440 valops.c (call_function): Comment about storing SP.
5442 * infrun.c (save_inferior_status): Save away the original bpstat
5443 chain so it can be restored later. Install the copied version for
5444 use by whoever saved the status. It will be blow away by
5445 restore_inferior_status, and the original chain restored. This is
5446 important for people who have pointers into the original.
5448 * breakpoint.c, command.h, copying.awk, dbxread.c, defs.h,
5449 findvar.c, frame.h, obstack.h, obstack.c, inflow.c, value.h,
5450 main.c, printcmd.c, sparc-tdep.c, symtab.c, valprint.c: lint
5453 Fri Sep 28 20:32:46 1990 John Gilmore (gnu at cygnus.com)
5455 * Makefile.dist: Roll version to 3.91.8. Add bfd.h and bfdconfig.h
5456 temporarily to the makefile. Add am29k-opcode.h and WHATS.NEW.
5457 Add stuff.c and kdb-start.c to the OTHERS list for tar files.
5459 Fri Sep 28 19:12:12 1990 John Gilmore (gnu at cygint)
5461 * Merge Mike Tiemann's multiple inheritance changes from Sun.
5462 Store the baseclasses in a type struct starting from array element
5463 0 rather than from the unusual array element 1.
5465 dbxread.c: the above.
5466 (virtual_context): Add
5467 Read new debug information about which virtual function table
5468 a virtual function is from, and store it in fn_field.fcontext.
5470 symtab.h: Add fcontextt. Fix baseclass indices. Typo in
5471 TYPE_FN_FIELD_STATIC_P.
5473 symtab.c: the above.
5474 valops.c: the above. Handle pointer casts of object *'s.
5475 (search_struct_method): Add.
5476 (value_struct_elt): First arg is now a pointer to a value, and is
5479 valprint.c: the above.
5480 values.c (value_virtual_fn_field): Add type arg. Handle
5481 offsetting to the proper object when calling virtual fns.
5483 (baseclass_addr): Add valuep arg.
5485 * README: Document the current state of BFD config (missing).
5486 * TODO, ChangeLog, Makefile.dist: Roll version.
5487 * WHATS.NEW: Add summary of changes since 3.5.
5489 Thu Sep 27 16:23:12 1990 John Gilmore (gnu at cygint)
5491 * dbxread.c (read_struct_type): Clear bit vectors whenever
5493 symtab.c (B_CLRALL): define.
5495 * tm-sparc.h (STORE_RETURN_VALUE): Avoid clobbering types by
5496 using == rather than =. Huh... This fixes the dreaded problem
5497 wherein builtin_type_int becomes TYPE_CODE_FLT.
5499 * core.c (info_files): Show the inferior pid.
5501 * config.gdb: Avoid putting "dir" command into .gdbinit. GDB
5502 already knows how to look in the source directory.
5504 * Remove psymtab hair from many places. Remove duplicated code
5505 for searching symbol tables. Hide psymtabs from most places.
5506 Make it fast to get from a psymtab to its symtab.
5508 blockframe.c (blockvector_for_pc): Remove psymtab hair.
5509 coffread.c (psymtab_to_symtab): Rename to psymtab_to_symtab2.
5510 mipsread.c (psymtab_to_symtab): Rename to psymtab_to_symtab2.
5511 dbxread.c: export psymtab_to_symtab, make it work if called N times.
5512 (psymtab_to_symtab): Rename to psymtab_to_symtab2. Initialize
5513 new symtab completely. New psymtabs get symtab pointer
5514 initialized to zero. Remove MI warning printf.
5515 symtab.h: Comments. Add psymtab to symtab pointer.
5516 (PSYMTAB_TO_SYMTAB): New macro.
5517 symtab.c: use PSYMTAB_TO_SYMTAB. Add psymtab_to_symtab and export it.
5518 source.c: use PSYMTAB_TO_SYMTAB. Remove symtab version and
5520 stack.c (backtrace_command): Avoid pre-pass to read symbols, if
5522 (print_frame_info): Avoid special-casing symbols that have not yet
5525 * source.c (open_source_file): Quick path if we have already
5526 located the source file by its full name.
5528 * symtab.c (lookup_symbol): Use find_pc_symtab rather than
5529 find_pc_psymtab. When a name is found in the misc function
5530 vector, search the symbol table for its mangled name, not the
5531 name that the user typed.
5533 * bfd.h: Fix missing comment terminators, make #endifs match.
5535 * valarith.c (value_less): Handle unsigned int comparisons.
5536 Add FIXME about pointer compares, which assume host and target
5537 pointers are the same.
5539 * command.c (do_nothing_command): lint
5540 dbxread.c: lint. Remove sort_syms. Document C++ visibility info,
5541 fix comments on debug symbol format for visibility. Actually set
5542 visibility of symbols.
5543 main.c (echo_command): lint; use <readline/history.h>.
5544 tm-sparc.h (FRAME_FIND_SAVED_REGS): lint
5545 obstack.h (_obstack_blank): Rearrange pointer math to avoid
5546 pointing past end of allocated memory; saber complains.
5547 obstack.h: Declare the external functions that we use.
5548 valarith.h: use <string.h>
5549 solib.c (solib_add): lint.
5551 Fri Sep 21 17:05:19 1990 John Gilmore (gnu at cygint)
5553 * main.c (initialize_main): Default info_verbose to off, now that
5554 symbol reading is fast.
5555 (quit_command): Avoid clobbering exec_bfd while quitting.
5557 * Initial BFD (binary file diddling library) merger:
5558 coffread.c: Change AOUTHDR to struct exe_hdr.
5560 core.c: initialize initialized data at compile time.
5561 (core_file_command): Move from coredep.c, convert to bfd.
5562 (xfer_core_file): Convert to bfd.
5563 exec.c (exec_file_command): use bfd routines.
5565 mips-tdep.c: Remove exec_file_command and friends.
5568 * coredep.c: (fetch_core_registers) Convert core_file_command to
5569 fetch_core_registers.
5570 mips-xdep.c, sparc-xdep.c, sun3-xdep.c: ditto.
5572 * utils.c: (error): Bogus crap, FIXME, to print bfd errors.
5573 (my_bfd_read): More bogosity, which I don't think we call.
5574 (program_name): Remove this atrocity asap!
5576 Wed Sep 19 13:36:41 1990 John Gilmore (gnu at cygint)
5579 values.c: allocate_repeat_value was not clearing the
5580 optimized_out field.
5581 (value_static_field): minor stylistic fix (wrong macro was used).
5582 valops.c (value_struct_elt_for_address): didn't work for C++
5585 * signame.c (_initialize_signame): Initialize signal names once.
5587 * breakpoint.h, command.c, copying.awk, defs.h, environ.c,
5588 exec.c, frame.h, infcmd.c, inferior.h, main.c, munch, sun3-xdep.c,
5589 symtab.h, tm-29k.h, valprint.c, value.h, values.c: Lint.
5591 * remote-eb.c: Support user-settable baud rates on the serial port.
5593 * tm-sun3.h (PREPARE_TO_STORE): fix typo.
5595 Fri Sep 14 13:28:29 1990 John Gilmore (gnu at cygint)
5597 * tconfig/sun3os4: Remove warning about native assembler,
5598 since it also occurs in the xconfig file.
5600 * findvar.c (registers): Allocate some slop after `registers'
5601 to prevent stray accesses from trashing the next variable.
5603 * tm-68k.h (REGISTER_BYTES): Allocate the right number of bytes
5604 on the sun-3, by changing the #ifdef from `sun3' (which is not
5605 defined by cc) to `sun'. Symptom was trashed builtin_type_XXX
5606 vars, which happened to follow `registers' in the executable.
5608 * readline/history.c (history_search): Heed gcc-2's advice
5609 and parenthesize && inside ||).
5611 * am29k-opcode.h, am29k-pinsn.c, am29k-tdep.c, remote-eb.c,
5612 tm-29k.c: Insert FSF copyright headers.
5614 * remote-eb.c: Better comments.
5616 * Makefile.dist: Update to 3.91.6.
5617 * TODO: note PREPARE_TO_STORE problem.
5619 Thu Sep 13 09:52:33 1990 Jim Kingdon (kingdon at cygint)
5621 * stack.c (frame_info): Only use FRAME_FIND_SAVED_REGS if defined.
5623 * remote.c: Wrap the whole file in #if !defined (SPECIAL_REMOTE).
5625 * infrun.c (wait_for_inferior, at end): Don't set up
5626 prev_* if the inferior no longer exists.
5628 * inferior.h (CALL_DUMMY_LOCATION): New macro, to replace
5629 CANNOT_EXECUTE_STACK.
5630 valops.c (call_function): Use it.
5632 * tm-convex.h: Add CALL_DUMMY_LENGTH for use by PC_IN_CALL_DUMMY.
5634 * inferior.h (PC_IN_CALL_DUMMY): New macro.
5635 infrun.c (wait_for_inferior, 2 places): Use it.
5637 * values.c (value_being_returned): Only use
5638 EXTRACT_STRUCT_VALUE_ADDRESS if defined.
5640 * Move PREPARE_TO_STORE from xm-sun3.h to tm-sun3.h to do the
5641 right thing for remote-eb.c.
5643 * sun3-xdep.c: Remove extraneous call to remote_store_registers.
5644 * sun386-xdep.c, hp300hpux-xdep.c, sparc-xdep.c: Ditto.
5646 * blockframe.c: Put get_frame_saved_regs inside #if !defined
5647 (FRAME_FIND_SAVED_REGS).
5649 * findvar.c ({fetch,store}_registers): Check for
5650 REMOTE_{FETCH_STORE}_REGISTER macro.
5652 * findvar.c (get_saved_register): Add argument lval and
5653 change meaning of argument addr.
5654 findvar.c: Change calls to get_saved_register to reflect
5655 new calling convention.
5656 valops.c (value_assign): Use get_saved_register instead of
5657 find_saved_register.
5659 Sun Sep 2 12:40:20 1990 Jim Kingdon (kingdon at cygint.cygnus.com)
5661 * coffread.c (read_one_sym): Make temp_aux an AUXENT, not
5662 an (uninitialized) pointer to one. Use "&" when passing it
5665 Fri Aug 31 22:57:54 1990 Jim Kingdon (kingdon at cygint.cygnus.com)
5667 * coffread.c (getfilename): Use DGUX x_offset and x_name if
5670 * coffread.c (symbol_file_command): Put semicolon after
5672 Put safe_to_init_tdesc_context in #if defined (TDESC).
5673 Put #ifdef TDESCs in 1st column for non-ANSI cpp's.
5674 coffread.c: #include <sys/stat.h>.
5675 (read_coff_symtab): Typo: in_source_files -> in_source_file.
5676 Add missing ')' in check for "lc%" and friends. Remove
5678 Declare read_one_sym() at top of file.
5679 (read_file_hdr): Put in extra #ifdefs so MC68MAGIC and
5680 MC68WRMAGIC can have the same value without causing a duplicate
5683 Thu Sep 13 15:55:36 1990 John Gilmore (gnu at cygint)
5685 * Allow a Makefile to be built without building the
5686 tm and xm file links that screw up builds in subdirectories.
5687 This is done with `config.gdb none', then you can do things
5688 like `make gdb.tar.Z'.
5689 * tconfig/none: Config file for no target system
5690 * xconfig/none: Config file for no host system
5691 * config.gdb: If no TM or XM files are called out by the
5692 host or target file, don't make links for them.
5694 * cplus-dem.c: Add documentation.
5696 * dbxread.c (read_ofile_symtab): Turn a fatal error into a
5697 simple error, so the user's gdb doesn't crash due to some object
5698 file problem (e.g. somebody is rebuilding the file out from under
5701 * printcmd.c (print_address_symbolic): demangle the symbol.
5703 * Makefile.dist (OTHERS): Remove tdesc-lib because it has
5704 Motorola copyrights in it. Make "make gdb.tar.Z" work.
5705 (alldeps.mak): sort and uniq all results from this; duplicates
5706 hose gdb.tar.Z link building. Remove RCS files from
5707 tconfig and xconfig. Add config files for sun386. Add
5708 a few odd files to OTHERS and HFILES.
5710 Mon Sep 10 21:20:24 1990 John Gilmore (gnu at cygint)
5712 * Makefile.dist: Pull solib.c to tconfig/sun?os4.
5713 Roll version number to 3.91.5. Make lint work in bindir.
5715 * README: Document cross-debugging and new file structure.
5717 * blockframe.c: Lint. Include "value.h" to declare read_register.
5718 (find_pc_partial_function): remove duplicate line.
5720 * command.h: Lint. Declare error_no_arg and dont_repeat.
5722 * tm-news.h: Remove inadvertently duplicated stuff.
5724 * mipsread.c: Remove cache_pc_function stuff, now done cleanly.
5725 Clean up usage of misc_function_type. Declare some CORE_ADDRs.
5727 * config.gdb: Allow `config.gdb host target' form. Clean
5728 up previous change that printed bogus messages when you just said
5731 * core.c: #include "command.h" for lint.
5734 * main.c: Remove some casts of enums. Lint.
5741 * printcmd.c (initialize_printcmd): Fix thinko in inspect cmd.
5743 * sparc-tdep.c (isannulled): Take instruction as parameter, don't
5744 read it from memory. This will allow us to save ptrace calls
5745 eventually. Changed caller single_step too.
5747 * sparc-xdep.c (fetch_inferior_registers): Avoid reading regs
5748 that we aren't going to use, saving many ptrace calls, especially
5749 when watchpointing or single stepping. Use some #define's for
5751 (store_inferior_registers): Ditto.
5752 (core_file_command): Use some #define's for constants.
5754 * tm-sparc.h: Add #define's for some register numbers, so we
5755 can eliminate the use of random constants in sparc-xdep.c.
5757 * stack.c (frame_command, print_frame_info, up_command,
5758 down_command) Remove frame_changed, since it
5759 causes a bug and doesn't seem to do anything useful. In some
5760 places it was used as a flag, in others as a stack level (?).
5762 * utils.c: Use MISSING_VPRINTF rather than HAVE_VPRINTF, so the
5763 default is to use the portable (vprintf) version rather than the
5765 * xm-news.h (MISSING_VPRINTF): Add.
5767 * valprint.c (val_print): Demangle fancy vtbl printouts. Lint.
5769 Sat Sep 8 00:24:12 1990 John Gilmore (gnu at cygint)
5771 * Remove stuff that forces -Bstatic linking of gdb, and warnings
5772 about linking debugged programs -Bstatic in the sun?os4 config
5773 files in tconfig and xconfig subdirectories.
5775 * main.c (main): Remove unreached exit(0) now that we exit
5778 * Create TODO file for online bug list. There are too many
5779 "little" bugs to keep track of on paper.
5781 * Change Projects file to refer to bug-gdb@cygnus.com
5782 rather than kingdon@ai.
5784 Fri Sep 7 23:35:15 1990 John Gilmore (gnu at cygint)
5786 * Makefile.dist (VERSION): 3.91.4 now.
5788 * symtab.c (init_misc_bunches): Rename from init_misc_functions.
5789 (condense_misc_bunches): Add sanity check that misc_count is
5790 the same as the number of symbols in the bunch.
5792 * coffread.c: rename init_misc_bunches. Pass an argument
5793 to condense_misc_bunches (a zero).
5795 * dbxread.c (partial_symbol_file_read): Call init_misc_bunches
5796 every time we are called; don't rely on our caller to do it.
5797 (add_file): Remove call to init_misc_bunches.
5799 * mipsread.c: Only warn, don't error, if unknown symbol types.
5800 This keeps an old gdb from falling on its face if it sees newly
5801 extended symbol info. Rename init_misc_bunches.
5803 Fri Sep 7 22:58:15 1990 John Gilmore (gnu at cygint)
5805 * Merge in changes from Per Bothner for DECstations and other
5806 MIPS stuff. The rest is Bothner speaking:
5808 The next message is a merger of Alessando Forin's mips port with
5809 mine. I've tried to use my good if biased judgment to get
5810 the best of both. It *does* need testing.
5812 Some of the changes are general, *not* mips-specific.
5815 Didn't believe in little-endian bit order.
5816 There are still inconsistencies about whether flags
5817 like BITS_BIG_ENDIAN are integer (#if ...) or
5818 boolean (#ifdef ...). I tried to paper over them.
5820 dbxread.c,coffread.c,mipsread.c,symtab.c,symtab.h:
5821 Moved some misc_function code that was common to
5822 {dbx,coff,mips}read.c to symtab.c.
5823 In the process, I think I cleaned things up a bit.
5824 At the same time, moved obsavestring and obconcat to symtab.c.
5827 Removed obsolete condense_addl_misc_bunches (use
5828 condense_misc_bunches(1) instead).
5831 Needed to include <sys/dir>, at least on DECstations.
5833 valops.c, mips-tdep.c, tm-mips.h:
5834 Added PUSH_ARGUMENTS macro to support funny argument-pushing
5835 conventions (when STACK_ALIGN is insufficient).
5836 Needed on mips, where doubles need 8-byte alignment,
5837 but ints only need 4.
5840 Removed cruft that was not being used.
5841 Merged in many fixes (most from Frank Yellin, fy@lucid.com).
5844 Print $ before register-names (I think that makes things a little
5846 Never print two instructions, even if one delays.
5847 Removed hex-disassemble set_cmd. (This is not mips-specific,
5848 so I think the argument is whether it is generally worthwhile or not.
5849 I'm inclined to think not, given how easy it is to
5850 convert between radixes in gdb.)
5853 This is basically Alessando's code.
5854 It doesn't use obstacks; I changed it to use obstacks
5855 in a few minor places where using malloc causes a
5856 memory leak. (Probably, more places could/should be changed.)
5857 I added record_misc_function where it was missing.
5858 In symbol_file_command and add_file_command, I tried
5859 to make the code consistent with more recent versions.
5860 Minor sylistic changes in parse_procedure.
5861 Make a .gdbinfo. psuedo-symbol point back to the real
5862 procedure symbol (using the isym field).
5865 This is basically from my port, but with a lot of details
5866 and a number of routines merged in from Alessando's version.
5867 I basically used my code "raw" backtrace (use heuristics
5868 from the actual code, rather than symbol table info) - though
5869 the idea is Alessandro's. I feel my code is a little cleaner
5870 here, particularly in being a little more flexible, such as being
5871 able to handle gcc-produced code (which it now can).
5872 It also doesn't do frame caching (which is not useful
5873 more recent gdb versions).
5874 I also used my code for push_/pop_dummy, more or less.
5875 I tried to incorporate AF's code for testing sigtramp
5876 while backtracing; I probably got it wrong.
5877 Added mips_print_register, which tries to scrunch as much
5878 information as possible on a screen...
5879 Removed the skip-prologue set_cmd. As with hex-disassemble (see
5880 under mips-pinsn.c), I don't see anything mips-specific here,
5881 and I don't see it being all that useful anyway.
5884 Added a $fp psuedo-reg distinct from $fp (nice for gcc).
5885 Use more register names (rather than hard-cases numbers).
5887 Thu Sep 6 18:33:15 1990 John Gilmore (gnu at cygint)
5889 * Hack up 3.90.11 changes:
5891 * Makefile.dist (depend): parameterize $(GCC).
5892 Add solib.c and solib.o.
5893 (readline): Fix vpath for both absolute or relative SRCDIR.
5895 * blockframe.c: Fix from Schaefer@asc.slb.com for shared libs.
5896 Also, let the part I didn't understand at least compile so
5897 I can test the rest. FIXME.
5899 * dbxread.c: Fix thinko using strcmp.
5900 (init_psymbol_list): declare static.
5901 (partial_symbol_file_open): Comment cleanups better, avoid
5902 cleaning up the string table since the caller will do that.
5903 Move the stat for mod time into symbol_file_command, temporarily.
5904 (There should be a mod time for each symbol file, eventually,
5905 to control its rereading. FIXME.)
5907 * infptrace.c (PT_WRITE_D): use same value as PT_WRITE_I for
5908 SunOS, which gives error for shared libs otherwise. (From
5909 Schaefer, probably FIXME needs work for portability.)
5911 * solib.c: Move #include "param.h" to work.
5912 Lowercase all the Uppercase Letters In the Messages.
5913 (find_solib): Clean up inferior_so_name for debug printouts.
5914 Allow no argument, to mean all shared libraries.
5916 * symmisc.c: include param.h to get CLEAR_SOLIB.
5918 Wed Sep 5 18:00:08 1990 John Gilmore (gnu at cygint)
5920 * Merge in Kingdon's changes from FSF: the diffs from 3.90.9
5921 to 3.90.11. ChangeLog entries below are from this.
5923 Wed Jun 13 09:17:39 1990 Jim Kingdon (kingdon at mole.ai.mit.edu)
5927 * Makefile.dist (HFILES): Add tm-sunos.h.
5929 Tue Jun 12 16:15:26 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5933 * Makefile.dist (gdb.tar.Z): Change linking of config so it works.
5935 Thu Jun 7 16:22:27 EDT 1990 Jay Fenlason (hack@ai.mit.edu)
5937 * sparc-opcode.h Added single-operand version of rett.
5939 Mon Jun 4 18:12:31 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5941 * m-sparc.h (REG_STRUCT_HAS_ADDR, STRUCT_ARG_SYM_GARBAGE):
5942 Put parens around gcc_p in expansion.
5944 Thu May 24 15:44:51 1990 Jim Kingdon (kingdon at mole.ai.mit.edu)
5946 * utils.c (lines_to_list): Return 10 if lines_per_page == 0.
5948 Wed May 23 16:36:04 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5950 * Changes for Sun shared libraries:
5951 blockframe.c (find_pc_partial_function): If a non-text symbol
5952 is found, set *address = pc - FUNCTION_START_OFFSET.
5953 breakpoint.c (insert_breakpoints) [DISABLE_UNSETTABLE_BREAK]:
5954 Disable breakpoints instead of giving an error.
5955 source.c (select_source_symtab): Initialize cs_pst.
5956 symmisc.c: Call CLEAR_SOLIB if defined.
5957 symtab.h: Make text{low,high} CORE_ADDR not int.
5958 (psymtab): New field addr.
5960 dbxread.c: Move DECLARE_FILE_HEADERS outside functions.
5961 (record_misc_function): Give correct type for N_DATA symbols.
5962 (condense_misc_bunches): do "misc_function_count = j" regardless
5964 Take code which is shared between symbol_file_command and
5965 add_file_command and put it into partial_symbol_file_{open,read}.
5966 Split add_file_command into add_file_command and add_file.
5967 Make psymtab_to_symtab read in the string table if the file
5969 Two new parameters to read_dbx_symtab and start_psymtab.
5970 tm-sunos.h: New file.
5972 Tue May 22 17:43:03 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5974 * infcmd.c: Change cont_command to continue_command and "cont"
5977 Mon May 21 14:41:41 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5979 * breakpoint.c (enable_breakpoint): Get value of watchpoint.
5981 * defs.h [sparc]: Use <alloca.h> regardless of __GNUC__.
5983 * values.c (USE_STRUCT_CONVENTION): Check for structures of
5984 size 1,2,4,8 rather than size < 8.
5986 * dbxread.c (dbx_lookup_type): Do f->length *= 2 as many times
5987 as necessary, not just once.
5989 * sparc-opcode.h: Add a bunch of new opcodes which Sun as supports.
5991 Thu May 17 15:04:09 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5993 * {t,x}m-sun386.h, sun386-xdep.c, {x,t}config/sun386
5995 * tm-news.h: Add CALL_DUMMY_*.
5997 * tm-68k.h: Remove duplicate comment at FRAME_FIND_SAVED_REGS.
5999 * config.gdb: In list_host, list_target, use ${i}, not $i.
6001 Tue May 15 21:27:12 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
6003 * source.c (find_source_lines) [BROKEN_LARGE_ALLOCA]: Use xmalloc.
6005 * sparc-opcode.h: Change all store floating-point state register
6006 instructions to have the right match & lose fields.
6008 Sat May 5 12:39:18 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
6010 * Makefile.dist: Move -I${srcdir} to GLOBAL_CFLAGS and pass
6012 config.gdb: If srcdir != ., create readline directory and
6013 copy a makefile into it.
6015 * wait.h, infrun.c: Change WRETCODE to WEXITSTATUS for
6016 consistency with POSIX.
6018 * breakpoint.c (bpstat_stop_status): Disable watchpoint
6019 when we exit its exp_valid_block.
6021 Tue Sep 4 11:46:46 1990 John Gilmore (gnu at cygint)
6023 * Makefile.dist: Bump version to 3.91.3.
6025 * Clean up handling of breakpoint commands (somewhat).
6026 Prompted by Tiemann bug report "cont 10" doesn't work any more.
6028 inferior.h: Add breakpoint_proceeded to inferior status struct
6029 and globals; save it and restore it.
6030 (clear_breakpoint_commands): Cleanup, remove old #define.
6032 infrun.c (clear_proceed_status): Set breakpoint_proceeded.
6033 (save_inferior_status, restore_inferior_status): handle it also.
6034 (proceed): Remove earlier code that set breakpoint_proceeded.
6035 It is now set only in clear_proceed_status.
6036 (clear_proceed_status): Cleanup, use bpstat_clear rather
6037 than clear_breakpoint_commands. No callers need the stop_bpstat
6038 between clear_proceed_status and proceed.
6040 infcmd.c: Add breakpoint_proceeded definition and comment.
6041 (cont_command, jump_command, signal_command): Move call to
6042 clear_proceed_status right next to call to proceed.
6044 breakpoint.c (bpstat_do_actions): Avoid clobbering our
6045 caller's argument while running down the chain of breakpoints.
6046 Use new variable "breakpoint_proceeded" to determine when
6047 a command that it executes moves the inferior past the
6049 (bpstat_clear): Handle NULL argument.
6050 (bpstat_clear_actions): Avoid useless call to
6051 breakpoint_auto_delete.
6052 (delete_breakpoint): Clean up bpstat's that are pointing to
6053 the deleted breakpoint from the stop_bpstat chain.
6054 (breakpoint_auto_delete): Simplify.
6056 * Clean up handling of EOF, error on stdin, etc. This was
6057 prompted by a network problem that caused gdb to go into an
6058 infinite loop filling up its malloc'd memory.
6060 main.c (return_to_top_level): Cleanup: call bpstat_clear_actions,
6061 not clear_breakpoints_commands, which is now gone.
6062 (main): If command_loop returns (e.g. from EOF on stdin), do
6063 a quit_command (looping back to command_loop if quit_command
6064 doesn't really quit).
6065 (command_loop): check result from command_line_input and
6066 exit if it returns NULL, rather than passing the NULL to
6068 (gdb_readline): Free malloc'd result space before returning
6071 * utils.c (query): Handle C-d to mean "yes", just as if the
6072 input was not a terminal. Also avoid infinite loop if EOF
6073 occurs in mid-input-line before newline. This allows
6074 query to be used at EOF on stdin with reasonable results.
6076 * infrun.c (proceed): Set breakpoint_proceeded.
6078 * values.c (value_as_long): Avoid infinite recursion for enums.
6079 (_initialize_values): Fix typo in help msg (kingdon).
6081 * Makefile.dist (RL_LIB): Use RL_LIB_DEP for dependencies,
6082 RL_LIB for linking. This allows -lreadline for linking
6083 and nothing for dependencies, once readline is a real library.
6085 * config.gdb: Jim Kingdon: give useful error message if the
6086 host or target type is not recognized.
6088 * defs.h (alloca): SPARC <alloca.h> does not declare alloca,
6089 it just defines it. Dumb, but deal with it.
6091 * Jim Kingdon suggests:
6092 in xconfig/sun3os4, CFLAGS should be XM_CFLAGS.
6094 Wed Aug 29 18:03:27 1990 John Gilmore (gnu at cygint)
6096 * Makefile.dist (VERSION): Bump version # to 3.91.2.
6098 * Clean up Bothner's changes.
6100 * blockframe.c (clear_pc_function_cache): New function.
6101 * blockframe.c: remake cache_pc_function_* static.
6102 * dbxread.c (symbol_file_command): remove references to
6103 cache_pc_function_* variables.
6104 * dbxread.c (read_struct_type): Use VOFFSET_STATIC.
6105 * printcmd.c: Avoid kludging a global variable (addressprint)
6106 to avoid printing the address of a string twice. Instead,
6107 pass the format letter 's' down low enough that it can be seen
6108 to avoid this problem.
6109 (print_formatted): Pass format arg to value_print.
6110 (restore_addressprint): Remove function.
6111 (do_examine): Avoid hacking addressprint, cleanups and such.
6112 (print_frame_args): Add a comment to a Bothner change.
6113 * symtab.h: define VOFFSET_STATIC and use it instead of "-1".
6114 * symmisc.c (free_all_symtabs): Call clear_pc_function_cache
6115 to wipe out the values cached in blockframe.c.
6116 * symtab.c (find_method): Add comment saying how big you must
6117 allocate to be "big enough". Per being terse again.
6118 * valprint.c (val_print): Handle format letter "s" to print
6119 strings without addresses. Add comment to vtbl printing code
6120 which casts with wild abandon. Rearrange reference-printing
6122 @0xaddr: value (print w/addressprint)
6123 value (print w/~addressprint)
6124 @0xaddr (parameter lists w/addressprint)
6125 or nothing (parameter lists w/o addressprint)
6127 Tue Aug 28 10:47:18 1990 John Gilmore (gnu at cygint)
6129 * Merge more changes from Per Bothner:
6131 Gdb's handling of TYPE_CODE_REF was so counter-C++ (and otherwise
6132 annoying) that I tried to improve it. Here are my suggestions.
6134 These patches all attempt to handle TYPE_CODE_REF (as in C++) better.
6137 Do automatic de-reference when taking the address of a reference.
6139 Don't deref_ref when printing parameter lists.
6141 More attempts at treating refernences properly.
6143 In val_print, if deref_ref==0, don't print dangling " = ".
6145 Add COERCE_REF macro, which de-references an REF.
6147 * Merge changes from Per Bothner:
6149 * Fixed (Sony news)-specific configuration problems.
6150 * Fixed other problems with using vanilla pcc and libc (enum problems;
6151 assumption that vsprintf exists).
6152 * Some major speed-ups (finc_pc_partial_function now caches a match;
6153 parsing avoids duplicate symbol_lookup calls).
6154 * Changed handling of baseclasses (no longer use baseclasses field
6155 of struct type, use the first n_baseclasses fields instead).
6156 * Various minor changes/fixes, most C++-related.
6159 Cache the most previous match from find_pc_partial_function.
6160 (Save both low and high ends of matching function's pc range.)
6161 This speeds up the loop of infrun.c:wait_for_inferior quite
6162 a bit, and makes step/next commands much zippier.
6164 Added an enum->int cast (otherwise, some compilers barf).
6166 No longer set baseclass offset to 0, since multiple
6167 inheritance now mostly works.
6168 Added a number of casts, to shut up compiler warnings
6169 (after stabs where made enums, not ints).
6170 When discarding a symbol table (in symbol_file_command),
6171 must clear the cache introduced in blockframe.c.
6172 Don't convert $vtbl_ptr_type to vtbl any more.
6173 Get rid of TYPE_BASECLASEES and baseclass_vec (see also symtab.h).
6174 Mask off sign bit emitted by g++ for virtual table offset.
6175 Set voffset to -1 (not 1) for static member functions.
6177 Changed parsing/lexing of names to avoid doing symbol lookup twice
6178 (once when lexing to determine symbol class, once for real).
6179 Now only call symbol_lookup once. Fields of 'this' win especially big.
6181 Subpress printing addr twice in the case of 'x/s addr'.
6183 lookup_basetype_type is no longer used.
6184 Add find_methods as recursive helper function to decode_line_1.
6185 This allows multiple inheritance to work.
6186 Also, once one or more matches has been found, do not look in
6187 base-classes. (Baseclass methods would be overridden, anyway.)
6189 Removed baseclasses array in struct type.
6190 Instead of using baseclasses[i], use fields[i-1].
6191 Added virtual_field_bits[i] to indicate if the i'th baseclass is virtual.
6192 Changed sign convention of voffset (previous was inconsistent).
6194 Some macros (CALL_DUMMY and relatives) were missing. Put them back.
6196 Used to assume existence of vsprintf. Re-written to not need it
6197 if HAVE_VPRINTF is undefined.
6199 typecmp was too pessimistic. Made it less so.
6201 Don't print space after address.
6202 If vtable points to a misc symbol (with 0 offset), print it,
6203 since that indicates the actual class of the object.
6204 Changed ype_print_derivation_info to use new inheritance
6205 scheme (without baseclasses vector).
6207 In value_primitive_field, fixed some bugs left over from previous set of fixes.
6208 Also, changes needed because TYPE_BASECLASSES were removed.
6210 REGISTER_U_ADDR didn't work for PC. Rewrote to use an array.
6212 Tue Aug 21 20:08:54 1990 John Gilmore (gnu at cygint)
6215 If there is no path set, and the symbols don't indicate what directory
6216 a file was compiled in, look in the current directory. But either
6217 a path or a known compilation directory will prevent this.
6220 Three independent bug fixes:
6221 * Remove the #if 0 block that breaks some stuff.
6222 * SunOS 4.1 fixed the promoted-parameter-wrong-addr bug in Sun C;
6223 adapt gdb to either SunOS 4.0.* or 4.1.
6224 * MAX_OF_TYPE and MIN_OF_TYPE thinko. By tedg@sun, I think.
6227 Instantiate the class T when looking for methods in it. (Tiemann@sun)
6230 (type_print) Demangle the name being printed.
6231 (type_print_base) Handle botched demangling without coredump (tiemann).
6234 (check_stub_method): Document routine.
6235 (tiemann) fix bug for no-arg functions
6236 Avoid clobbering beyond end of malloc'd storage.
6237 Terminate the argument list properly.
6239 Sat Aug 18 01:29:59 1990 Per Bothner (bothner@cs.wisc.edu)
6241 * Changes merged by John Gilmore:
6244 In breakpoint_1, use new print_address_symbolic instead
6245 of find_pc_partial_function. (This forces use of assembler-level
6246 addresses, and avoids misleading non-mangled source-level names.)
6248 Generalize ansi argument such that -1 means skip arglist totally.
6249 Removed global variable print_ansi_qualifiers (which made
6250 code non-reentrant), in favor of extra explicit arguments
6251 to internal routines.
6253 Add new helper function print_address_symbolic.
6254 Use find_pc_misc_function instead of find_pc_partial_function
6255 (since we want assembler-level symbols here).
6257 Print unknown function as just "f (...)", not "f (...) (...)".
6258 Use new fputs_demangled explicitly.
6260 Fixed a typing violation (problem: value.h cannot be imported
6261 without renaming many variable in this file).
6262 lookup_symbol: If no matching misc_func, look for a C++-mangled name.
6263 decode_line_1: Moved forward some never-reached code.
6264 Made decode_line_2 skip function prologues correctly.
6266 fputs_filtered should not demangle by default.
6267 Add new fputs_demangled to demangle on demand..
6269 Change value_struct_elt to use value_primitive_field (using recursive
6270 utility function search_struct_field). This allows foo.bar to work
6271 for multiple inheritance (so far only for data fields).
6272 Change check_field in the same way (recursive helper function
6273 to support multiple inheritance).
6274 (Note: there are more of these problems that I haven't fixed.
6275 Any code that says TYPE_BASECLASS (t, 1) is probably wrong.)
6276 value_of_this: 'this' symbol name is now just "this", note "$this".
6278 Don't print static members.
6279 Avoid printing "members of <type>" if there are none.
6280 Simplified type_print_derivation_info by merging duplicate code.
6281 Remove useless blank lines in type_print_base (ptype command).
6283 Added declaration of new routine value_primitive_field.
6285 Added value_primitive_field which is generalized version of
6286 value_field that can handle multiple inheritance (non-zero offsets etc).
6287 Re-implemented value_field to call value_primitive_field.
6289 Fri Aug 17 23:33:44 1990 John Gilmore (gnu at cygint)
6291 * infcmd.c -- insert else to avoid 'delete env' coredump when you
6292 delete the whole environment. Karl Berry reported the bug.
6293 * source.c - fix openp to avoid //'s in filenames, which
6294 trigger an Emacs bug causing it to not be able to find files
6295 when running gdb in a window.
6296 * dbxread.c - zap the #if 0 that botches the add-file code.
6297 It seems to work a lot better without all the code commented out.
6299 Fri Jul 20 16:58:46 1990 John Gilmore (gnu at cygnus.com)
6301 * Merge Tiemann's and Ted Goldstein's changes, detailed below,
6304 Tue Jul 17 19:34:33 1990 Ted Goldstein (tedg at golem)
6306 * Makefile - added a ${CFLAGS} to a couple of entries,
6307 added remote-sa.sparc.c
6308 * added remote.sa-sparc.c, a modification of remote.c
6309 which conducts a dialog directly with the SparcStation prom.
6310 * breakpoint.c, infrun.c, sparcdep.c added
6311 remote_insert_breakpoint(), and remote_remove_breakpoint()
6312 to breakpoint.c instead of directly writing breakpoint instructions.
6313 * sparcdep.c on remote_debugging,there is no need
6314 to remove signle step breakpoint instructions.
6315 * main.c added "-epoch" flag and "int epoch_interface" to main.c
6317 * printcmd.c - epoch interface sends lisp expressions to open up
6318 epoch windows on inspection.
6319 * valprint.c - added arrayprint, and addressprint and made adding
6320 format controls easier
6321 * wait.h added a couple of undef's because we were getting
6322 complaints about WSTOPSIG and WTERMSIG begin redefined.
6325 Wed Jul 4 05:27:51 1990 Michael Tiemann (tiemann at masham)
6327 * symtab.c (decode_line_1): Add support for handling method stubs
6328 in the type information.
6330 Tue Jul 3 09:39:18 1990 Michael Tiemann (tiemann at masham)
6332 * values.c (baseclass_addr): Run loop from INDEX+1 to
6333 N_BASECLASSES; otherwise, we can still get into a loop.
6334 @@ This should be restructured to use a cleaner search strategy.
6336 Sun Jul 1 12:28:51 1990 Michael Tiemann (tiemann at masham)
6338 * dbxread.c (define_symbol,read_type): Grok GNU C++'s new
6339 abbreviation "Tt" for tags which have the same name as their
6342 Fri Jun 29 01:03:46 1990 Michael Tiemann (tiemann at masham)
6344 * symtab.c (list_symbols): add ability to set breakpoints on all
6345 the functions which match a particular regular expression.
6347 Tue Jun 26 04:26:29 1990 Michael Tiemann (tiemann at masham)
6349 * cplus-dem.c (cplus_demangle): New parameter ANSI says whether we
6350 should print ANSI qualifiers (such as `const' and `volatile').
6351 All callers changed to call with ANSI == 1, except from
6352 `check_method_stub', which uses old-style syntax.
6354 * symseg.h (struct fn_field): Remove unneccessary `args' field.
6355 * symtab.h (TYPE_FN_FIELD_ARGS): Redefined.
6357 * values.c (check_stub_method): New function.
6359 * cplus-dem.c (do_type): Handle "long long" (encoded as 'x').
6361 * dbxread.c (read_type): Handle new GNU C++ method type stubs.
6362 * valprint (type_print_base): Ditto.
6364 * symtab.c (gdb_mangle_typename): New function.
6366 Tue Jun 5 00:18:43 1990 Michael Tiemann (tiemann at gzilla)
6368 * breakpoint.c (catch_command): New function. Provides a
6369 mechanism to set breakpoints based on catch clauses.
6370 (disable_catch): Similar, but disables breakpoints on catch
6372 (delete_catch): Similar, but deleted breakpoints on catch clauses.
6374 Sun Jun 3 22:54:08 1990 Michael Tiemann (tiemann at gzilla)
6376 * blockframe.c (blockvector_for_pc): New function.
6377 * blockframe.c (block_for_pc): Changed to call
6378 `blockvector_for_pc' and get the block itself.
6380 * stack.c (catch_info): New function. Prints info about
6381 exceptions which can be caught in the current frame.
6382 * stack.c (print_frame_label_vars): New function. Similar to
6383 `print_frame_local_vars'.
6384 * stack.c (print_block_frame_labels): Prints out labels that are
6385 defined in this frame. These labels are exceptions that can be
6388 * dbxread.c: Updated to handle N_CATCH symtab types.
6390 Thu May 3 22:10:00 1990 Michael Tiemann (tiemann at teacake)
6392 * valprint.c (everywhere): TYPE_NAME (TYPE) no longer comes in the
6393 form "struct ..." for GNU C++. Don't flush any part of TYPE_NAME
6394 when printing the type.
6396 Wed May 2 22:43:04 1990 Michael Tiemann (tiemann at teacake)
