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

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

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

274 (allocate_symtab): Takes objfile as new parameter, chains them.
275 Handle INIT_EXTRA_SYMTAB_INFO.

278 * dbxread.c: Make more errors into complaints.
279 (push_subfile, pop_subfile): Move to buildsym.c.
280 (dbx_symfile_read, dbx_symfile_init, fill_symbuf, read_dbx_symtab,
281 start_psymtab, psymtab_to_symtab_1, read_ofile_symtab,
282 dbx_psymtab_to_symtab, ): Use bfd ops, don't use file descriptor.
283 Pass objfile. Change callers.
284 (fill_symbuf, SWAP_SYMBOL): Take bfd as arg.
285 (read_dbx_symtab): Just wipe out new symbols, not all, on error.
286 (end_psymtab): Blow away psymtab if empty.

291 * buildsym.c (end_symtab): Pass objfile.
292 (dbx_lookup_type): Handle null typevector.
293 (dbx_alloc_type): Check file number, not sym number, for -1.
294 (find_symbol_in_list): Add for xcoffread.
295 (start_symtab): Default typevector is empty. Keep reusing same
297 (end_symtab): Take objfile argument and pass it to
298 allocate_symtab. Don't make a symtab if no blocks or symbols.
299 Handle empty typevector.
300 (push_context): New function for context stack nesting.
301 (read_type): Mark FIXME where we need to reintroduce type smashing.
303 * buildsym.h (pop_context): Macro, paired with push_context.
304 (subfile_stack): Move here from dbxread.c.
306 * coffread.c (end_symtab, read_coff_symtab): Take and use objfile arg.
307 (read_coff_symtab): Cleanup by freeing objfile, not all symtabs.
309 * mipsread.c (read_mips_symtab, parse_partial_symbols, parse_fdr,
310 new_psymtab, new_symtab): Take and use objfile arg.
312 * dwarfread.c (scan_compilation_units, start_psymtab,
313 process_dies, end_symtab, dwarf_build_psymtabs,
314 read_lexical_block_scope, read_func_scope, read_file_scope): Take
315 and use objfile argument.
316 (psymtab_to_symtab_1, read_ofile_symtab): Don't take or use file
317 descriptor. Use BFD internal functions instead.
318 (end_symtab): Call global allocate_symtab.
320 * elfread.c, target.c: Minor changes to accommodate objfiles.
321 * symtab.h: partial_symbol_table has no symfile_name member now.
322 (fn_fieldlists voffset): avoid non-int bitfield.
323 (struct symtab): Add objfile * and objfile_chain * of symtabs.
324 (struct partial_symtab): Add objfile * and objfile_chain * of
325 psymtabs. Remove symfile_name.
327 * symmisc.c: Lose free_all_symtabs, free_all_psymtabs.
328 (printsyms_command): Rename from print_symtabs. Add selective
329 listing if 2nd argument given. Print objfile info.
330 (printpsyms_command): Rename from print_partial_symtabs. Ditto all.
331 (printobjfiles_command): New; prints objfiles lists, and checks
332 for consistency of symtab, psymtab, and objfile lists.
334 * symfile.h, symfile.c, symtab.h: Lint
336 Fri Nov 8 23:38:48 1991 John Gilmore (gnu at cygnus.com)
338 * command.c: Include param.h.
339 * defs.h (warning_setup, warning): Declare.
340 * expprint.c (print_subexp, UNOP_MEMVAL case): Lint.
341 * inflow.c (new_tty): Use USE_O_NOCTTY #define.
342 * language.c, printcmd.c (print_scalar_formatted), signame.c,
345 Thu Nov 7 18:26:15 1991 Steve Chamberlain (sac at rtl.cygnus.com)
347 * Makefile.in: link with libiberty after libreadline, since
348 readline might want something in libiberty.
349 * m88k-xdep.c: Fixed the register offsets in the ptrace_user
350 struct for BCS 88k machines.
351 * xm-m88k.h: don't define USIZE if already defined.
352 * configure.in: Added delta88 target.
354 Thu Nov 7 04:51:19 1991 John Gilmore (gnu at cygnus.com)
356 * am29k-pinsn.c, am29k-opcode.h: Fix decoding of mtacc, dmac, fmac.
358 * tm-*.h: Remove READ_DBX_FORMAT, COFF_FORMAT, and
359 READ_MIPS_FORMAT, which have been unused since BFD. Still
360 remaining is COFF_NO_LONG_FILE_NAMES.
361 * tm-sun3.h, tm-altos.h: Remove detritus accidentally left from
362 function calling code moved to m68k-tdep.c.
364 Wed Nov 6 17:21:59 1991 John Gilmore (gnu at cygnus.com)
366 * coffread.c: Eliminate c_nsyms in favor of c_naux.
367 Complain if no auxents on .bf and .ef FCN symbols, and assume
368 lots of line numbers.
369 (init_linenos, enter_linenos): Use a sentinel at the end of the
370 read-in linenos, to make for a fast, safe loop-end test.
372 Wed Nov 6 02:54:08 1991 Steve Chamberlain (sac at cygnus.com)
374 * coffread.c (read_coff_symtab): coffread used to rely on the
375 x_sym.x_misc.x_lnsz.x_lnno field giving the # of linnos in a
376 function. Two of the formats I'm using (29k and 88k) don't seem to
377 set it. Ths patch to fcn_last_line and (enter_linenos) is an
378 attempt to use the actual size of the linno table in the file to set
379 the number of linenos to process.
381 Tue Nov 5 22:47:46 1991 Steve Chamberlain (sac at cygnus.com)
383 * Makefile.in: put a - infront of the mv y.tab.c c-exp.tab.c and
384 mv y.tab.c m2-exp.tab.c, so that if bison is used, and the files
385 are created in place, so the mv fails, then the make continues.
387 Tue Nov 5 16:47:47 1991 Per Bothner (bothner at cygnus.com)
389 Add C++ as a separate language.
390 * defs.h (enum language): Add language_cplus.
391 * dwarfread.c (end_symtab): Support language_cplus.
392 * c-exp.y: Add new struct language_defn cplus_language_defn.
393 Don't set c to be the default language (see main.c).
394 * c-exp.y (yylex): Only look for field of this if
395 language is C++. (First difference from C!)
396 * language.c: Add case branches for C++ (currently, all
397 the same as C). Also, add c++ to "usage" note for "set lang".
398 * valprint.c (typedef_print). Add case branches for C++.
399 * main.c (main): New way to set initial language: Look at
400 file extension of psymtab containing main(). (Same as we
401 do for symtabs, but avoid loading the symtab yet.)
402 * symtab.c: New routine find_main_psymtab(), used by main()
403 to set initial language.
404 * symfile.c (allocate_symtab): Move code for mapping file
405 extensions-> languages to new deduce_language_from_filename().
407 Fix a C++ problem when looking for methods in super-classes.
408 There was confusion between base and derived types.
409 * valops.c (value_fn_field): Change function interface.
410 * values.c: Use new value_fn_field interface.
412 Mon Nov 4 10:49:33 1991 Per Bothner (bothner at cygnus.com)
414 * infrun.c: Fixed typo in comment.
415 * utils.c: All the v*fprintf emulation is now in libiberty,
416 so we can get rid of some junk.
417 * xm-sun3os4.h, xm-sun4os4.h, xconfig/decstation, xconfig/i386sco,
418 xconfig/sun3os4, xconfig/sun4os4: Don`t need HAVE_STRSTR any more.
419 * m68k-pinsn.c (print_insn_arg): Support BB/BW/BL
420 type operands, as used by branch instructions.
421 * gmalloc.c: Fix prototype of memcpy.
422 * elfread.c: Comment out register_addr, since it conflicts
423 with the one in coredep.c.
424 * buildsym.h: Remove extern declarations of two functions
425 that are really static in buildsym.c.
426 * tm-mips.h: Add symbolic names for more registers.
427 * mips-xdep.c (store_inferior_registers): Use new register names.
428 * xm-mips.h: Simplify REGISTER_U_ADDR, since it is now
429 only used for core files, not ptrace. Therefore,
430 the KERNEL_U_ADDR hack is no longer needed.
431 The mapping to ptrace number is now in in mips-xdep.c.
432 * mips-xdep.c: Define REGISTER_PTRACE_ADDR (using the
433 mapping from the old REGISTER_U_ADDR), and use it
434 in {fetch,store}_inferior_registers.
435 * mipsread.c: Rename #include ecoff.h to new name coff-mips.h.
436 * mips-tdep.c (mips_push_dummy_frame, mips_pop_frame):
437 Save/restore FP regs correctly (?).
438 * dbxread.c: Remove duplicate define_symbol and type_synonym_name
439 (these had been previously moved to buildsym.c).
440 Hence, define_symbol becomes extern instead of static.
441 * buildsym.c (read_struct_type): Comment out bogus handling
442 of C++ operator methods. Minor hacking of reading of class
443 contexts. Make define_symbol non-static, so dbxread.c can call it.
445 Fri Nov 1 11:05:47 1991 John Gilmore (gnu at cygnus.com)
447 * mipsread.c (read_mips_symtab, read_the_mips_symtab): Use real
448 filename with error messages.
449 * stack.c (frame_select_command): Rename to select_frame_command
450 to avoid "fr" and "fra" having nonunique completions.
451 * symfile.c (sort_symtab_syms): Ignore sort of zero symtab *.
452 (symfile_init): Print file format name when unable to handle it.
453 (free_named_symtabs): Use BLOCKVECTOR rather than obsolete BLOCKLIST.
454 * symmisc.c (free_symtab): Only free linetable if nonzero.
455 * symtab.h: Remove obsolete BLOCKLIST macros.
457 Thu Oct 31 18:12:43 1991 Stu Grossman (grossman at cygnus.com)
459 * infrun.c (wait_for_inferior): another stepi/nexti fix. Ensure
460 that stop_step is 1 at bottom of main loop. I don't know why this
461 needs to be done, but it helps me sleep better at night.
463 Sun Oct 27 18:18:39 1991 Stu Grossman (grossman at cygnus.com)
465 * main.c (initialize_history): Read history after reading all
468 Sun Oct 27 14:09:25 1991 John Gilmore (gnu at cygnus.com)
470 * buildsym.c: Break out initial malloc sizes.
471 (record_line): Record directly in a subfile. Alloc on demand.
472 (compare_line_numbers): Add from xcoffread.c.
473 (end_symtab): New params say whether to sort pendings and
474 linetable. Patch block stabs if defined. Shrink linetable before
475 allocating the symtab.
476 * buildsym.h: Delete line_vector* and prev_line_number. Add
477 global_stabs and file_stabs for xcoffread.
478 * dbxread.c (start_subfile): Move to buildsym. Change above calls.
479 * symtab.h: LINETABLE(symtab) can now be null. Zap LINELIST.
480 * symmisc.c, symtab.c: Cope with null LINETABLEs.
482 * blockframe.c: Pass fromleaf to INIT_EXTRA_FRAME_INFO.
483 * tm-29k.h, tm-88k.h, tm-i960.h, tm-irix3.h, tm-mips.h, tm-pyr.h,
484 tm-sparc.h: Accept fromleaf parameter.
485 * c-exp.y (yyerror): Pass error message if given.
486 * configure.in: Add rs6000 host and target.
487 * inflow.c (new_tty): O_NOCTTY kludge for RS/6000.
488 * symfile.h (entry_point): Add.
490 Sat Oct 26 00:16:32 1991 John Gilmore (gnu at cygus.com)
492 * buildsym.c: New file. Breaks out symbol-table-building routines
493 from dbxread.c, so they can be shared with xcoffread.c.
494 * buildsym.h: New file. Declarations for buildsym.c users.
495 * dbxread.c: Remove large chunks into buildsym.c.
496 * Makefile.in: Add buildsym.c and buildsym.h.
498 * symfile.c (syms_from_bfd): New routine.
499 (add_symbol_file): Call it to do the real work.
500 (syms_from_bfd): Initialize entry_point before calling symfile_init.
501 * symtab.h, symfile.c, coffread.c, mipsread.c, dwarfread.c:
502 Avoid declaring or setting entry_point (symfile.h & symfile.c cope).
504 Fri Oct 25 10:58:16 1991 Mark Eichin (eichin at cygnus.com)
506 * cplus-dem.c (cplus-demangle): added support for templates, static
507 data, and the new (correct) mangling for destructors.
509 * dwarfread.c: (dwarfwarn): created a varargs version of
510 dwarfwarn, for non __STDC__ compilers.
512 * c-exp.y: (yylex): added match for "template" token.
513 (typebase): added TEMPLATE name '<' type '>' clause, for explicit
514 specification of template types.
516 * symtab.c: (lookup_template_type): new function for finding
517 templates in symbol table.
518 (type_name_no_tag): changed to explicitly check for s/u/e at the
519 beginning of the symbol - if it is a template, none of these will
520 be there (but the name will still contain spaces.)
522 Fri Oct 25 18:59:32 1991 Per Bothner (bothner at cygnus.com)
524 Various fixes to improve g++ debugging.
525 * symtab.h: Add is_const and is_volatile flags for each method.
526 These are bit fields - take their space from voffset,
527 which shrinks to 30 bits. Since voffset is now a bitfield,
528 make it unsigned for portability. This changes its interpretation
529 slightly: Static methods now have voffset 1 instead of -1,
530 and virtual offsets start at 2, not 1.
531 * symtab.c: Renamed gdb_mangle_typename to gdb_mangle_name,
532 since it now returns an entire magled method name, not just
533 the type part. This avoids some duplication.
534 It also allows us to correctly mangle const and volatile
535 methods (using the new is_const and is_volatile bit fields
537 * valprint.c (type_print_base), values.c (check_stub_method):
538 Simplify by using new gdb_mangle_name.
539 * values.c (value_headof): Fix to correctly handle single
540 inheritance (actually two fixes, either of which suffices).
541 * dbxread.c (read_struct_type): Handle const and volatile
543 * dbxread.c (read_struct_type): Yet one more place where
544 we must handle '\\' continuations.
545 * valprint.c (vtbl_ptr_name): Add final '\0'.
547 Fri Oct 25 16:06:38 1991 Stu Grossman (grossman at cygnus.com)
549 * tm-sparc.h, tm-68k.h (EXTRACT_RETURN_VALUE): fix output of
550 short return values for sparc and 68k. Patch from Paul Eggert.
552 * coffread.c, coredep.c, i386-xdep.c: install patches for
553 SysV/386 3.2 from Mauro DePalma.
555 Fri Oct 25 02:02:13 1991 John Gilmore (gnu at cygnus.com)
557 * core.c (core_file_info), exec.c (exec_file_info): Print file
558 type. Use printf_filtered.
560 * valops.c (value_fetch_lazy): Avoid 0-length fetches.
562 Thu Oct 24 23:06:40 1991 Fred Fish (fnf at cygnus.com)
564 * dwarfread.c: Add casts to remove compiler warnings.
566 * tm-3b1.h, tm-68k.h, tm-altos.h, tm-amix.h, tm-hp300bsd.h,
567 tm-hp300hpux.h, tm-isi.h, tm-news.h, tm-pn.h, tm-sun2.h,
568 tm-sun3.h: Remove locally duplicated code for calling functions
569 in the inferior. The only differences were in the specific trap
570 vectors used and whether or not an fpu was present. These are
571 now handled by appropriate definitions of BPT_VECTOR and
572 HAVE_68881 respectively. Other minor obvious cleanups.
574 * valops.c: Correct a minor misspelling.
576 * utils.c: Remove local BSD/USG hacks that are now in libiberty.
578 * dwarfread.c: Remove prototype for dwarfwarn. Does not work
581 Thu Oct 24 09:33:44 1991 John Gilmore (gnu at cygnus.com)
583 * stack.c (frame_command): Always print. Use new
584 frame_select_command to select a frame without printing.
586 * dwarfread.c: Use <varargs.h>, since <stdarg.h> is not portable.
588 Thu Oct 24 01:32:51 1991 Fred Fish (fnf at cygnus.com)
590 * dwarfread.c: New file for DWARF debugging format support.
592 * elfread.c: New file for ELF object file format support.
594 * procfs.c: New file for SVR4 /proc (process file system) support.
596 * tm-amix.h, xm-amix.h, tconfig/amix, xconfig/amix: New files for
599 * xm-svr4.h, tm-svr4.h: New files for SVR4 support.
601 * xm-m68k.h: New file for host machines with m68k cpu.
603 * Makefile.in: Add elfread.c and dwarfread.c to SFILES_MAINDIR.
604 Add elfread.o and dwarfread.o to OBS.
606 * symfile.h: Add "elf" to list of supported formats in comment.
608 * c-exp.y, defs.h, symtab.h, valprint.c: Add three new builtin
609 types to gdb, builtin_type_long_double, builtin_type_complex, and
610 builtin_type_double_complex. Add and use new TARGET_SHORT_BIT,
611 TARGET_INT_BIT, TARGET_LONG_BIT, TARGET_FLOAT_BIT,
612 TARGET_DOUBLE_BIT, TARGET_LONG_DOUBLE_BIT, TARGET_COMPLEX_BIT, and
613 TARGET_DOUBLE_COMPLEX_BIT, as the sizes in bits of the indicated
614 types on the target machine (ala the existing TARGET_LONG_LONG_BIT).
616 * infrun.c: When using SVR4 /proc interface instead of ptrace(),
617 call proc_set_exec_trap() to setup child to stop at first instruction.
619 * inftarg.c: When using SVR4 /proc interface, call proc_wait()
622 * m68k-tdep.c: Add new routines supply_gregset(), fill_gregset(),
623 supply_fpregset(), and fill_fpregset(), which are machine
624 dependent support routines for SVR4 /proc interface.
626 * utils.c: Add warning_setup() and warning(). Warning() behaves
627 the same as error() except that it returns normally rather than
628 jumping back to command level. Modules that don't want to call
629 warning() for some reason, but want to produce their own warnings,
630 can call warning_setup() to ensure compatibility with the way
631 warning() and error() deal with the terminal.
633 * symtab.c: Make internal errors produce more useful messages.
635 * tm-68k.h: Move code that is duplicated in almost every single
636 m68k based machine's configuration files to this common file.
637 Duplications in the configuration files still need to be removed
640 * infrun.c (child_create_inferior): System V versions must call
641 setpgrp() with no arguments, to comply with prototyping typically
644 * munch: Add support for SVR4 style nm output.
646 * dbxread.c, mipsread.c symmisc.c, symtab.c: Remove the object
647 file specific fields from the partial symbol table structure and
648 replace them with a pointer to private data for each different
649 flavor of object file reader to initialize appropriately.
651 Wed Oct 23 09:38:20 1991 John Gilmore (gnu at cygnus.com)
653 * xconfig/sun[34]os4: Add note about strstr botch on sunos4.0.3c
656 * mipsread.c (fixup_undef_type): New function. If a struct /
657 union / enum is defined in a header file but nowhere else used,
658 (by typedefing, pointer referencing or declaration) the mipsread code
659 builds the complete tree for the structure but leaves its code as
660 TYPE_CODE_UNDEF as it doesn't know what kind of aggregate it is.
661 Guess its type based on the details of the members.
663 Tue Oct 22 18:04:32 1991 Stu Grossman (grossman at cygnus.com)
665 * infrun.c (wait_for_inferior): Check return value from
668 Mon Oct 21 17:47:03 1991 Stu Grossman (grossman at cygnus.com)
670 * infrun.c (wait_for_inferior): fix stepi/nexti that was broken
671 by my last edit to this routine.
673 Mon Oct 21 14:27:43 1991 John Gilmore (gnu at cygnus.com)
675 * tm-sun3.h (FIX_CALL_DUMMY): problem with cross debugging.
676 FIX_CALL_DUMMY does unaligned accesses and/or forgets to byte swap
677 the values before putting them into the dummy code. (From Peter
680 Mon Oct 21 10:04:39 1991 Steve Chamberlain (steve at rtl.cygnus.com)
682 * configure.in: added ebmon target.
684 Wed Oct 16 22:49:58 1991 John Gilmore (gnu at cygnus.com)
688 * Makefile.in: Roll VERSION to 4.2.
689 * README, TODO, WHATS.NEW: Update.
691 * core.c (core_open): Improve error message for bad file.
692 Pass .reg virtual memory address to fetch_core_registers to help
693 it find the registers in the core-file header.
694 * coredep.c (fetch_core_registers): Take new argument, use it,
695 and pass it to register_addr to locate the block of registers.
696 * xm-mips.h: Update KERNEL_U_ADDR for new scheme. Cleanup a bit.
698 * dbxread.c (read_dbx_symtab, process_one_symbol): Handle
699 Sequent N_FN_SEQ like everybody else's N_FN.
701 * main.c: Circumvent SCO cc bug with #if !!defined(USG).
702 * tm-i386v.h: #endif guck.
703 * xconfig/i386*: Remove -Dgetpagesize()=4096 kludge.
704 * xconfig/i386sco: Add HAVE_STRSTR to avoid ANSI bdeath.
705 * xconfig/tahoe: Add REGEX, which seems to be missing.
707 * coredep.c: Add <sys/types.h> for SCOnix.
708 * dbxread.c (read_dbx_symntab): Avoid coredump on malformed file.
709 * printcmd.c (print_formatted): Flush output before disassembly.
711 Tue Oct 15 20:12:32 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
713 * doc/refcard.tex (sec "Working Files"): consistent metavars and
714 other improvements, due to comments by François Pinard
715 (pinard@iro.umontreal.ca)
717 * doc/gdb.texinfo (appendix "Installing GDB"): changes in
718 configure, and improvenets related to Pinard's refcard comments
720 Tue Oct 15 08:45:12 1991 John Gilmore (gnu at cygnus.com)
722 Changes from Fred Fish:
723 * tm-68k.h (FPI_REGNUM): Add.
724 * infrun.c (child_create_inferior): flush stdout and stderr

727 * inflow.c: Handle TIOCGLTC_BROKEN for Amiga.
730 * values.c (show_convenience): Use printf_filtered.

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

755 * m68k-tdep.c (m68k_push_dummy_frame, m68k_pop_frame): Add
756 generic routines for calling inferior functions.
758 * blockframe.c (inside_main_scope, inside_entry_scope): New.
760 * copying.awk: Filter formfeeds out of copying & warrantee.
761 Make them available as `show copying' and `show warrantee' also.
762 * main.c (print_gnu_advertisement): Advt `show' commands.
764 Thu Oct 10 17:25:47 1991 John Gilmore (gnu at cygnus.com)

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

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

909 Fri Sep 20 16:10:52 1991 John Gilmore (gnu at cygnus.com)
913 * Makefile.in (VERSION): Set to 4.1.
914 * language.c (set_language_command): Print useful help message,
915 and restore the language string after giving help.
916 * valprint.c (typedef_print): Print typedef in C or M2.
917 * symtab.c (list_symbols): Use it.
918 * main.c (main): Avoid any output before (gdb) prompt when -q.
919 * language.c (set_language_command): Handle errors by restoring
920 the language string to its current state (fix from A. Beers).
921 * doc/gdbint.texinfo: Roll in information from README. Rearrange
922 "how to install" and "how to print the doc" stuff so it drops
924 * configure.in: Rename rtpc CPU to romp to match config.sub.
925 * README, WHATS.NEW, TODO: Update for gdb-4.1.
927 Fri Sep 20 17:39:14 1991 Roland H. Pesch (pesch at cygnus.com)
929 * doc/gdb.texinfo: Updates from ChangeLog. set/show write,
930 autoloading shared libs, copyright etc on GDB startup, clean up $_
931 and $__ index refs, set/show listsize and related updates to list
932 cmd. New host/target configs.
934 Fri Sep 20 15:46:00 1991 Roland H. Pesch (pesch at cygnus.com)
936 * doc/Makefile: generate aux version-no file doc/gdbVN.m4
937 from main Makefile.in version definition
938 doc/gdb.texinfo: use version recorded in doc/gdbVN.m4 for current
940 Makefile.in (setup-to-dist): generate doc/gdbVN.m4
942 * doc/gdb.texinfo: merge new language-switching and lang-specific
945 Fri Sep 20 15:00:57 1991 Per Bothner (bothner at cygnus.com)
947 * mcheck.c: Add __ONEFILE kludge to allow compilation by non-ANSI
948 compilers (which may lack stddef.h).
950 Fri Sep 20 13:29:42 1991 John Gilmore (gnu at cygnus.com)
952 * dbxread.c (read_dbx_symtab, process_one_symbol): N_FN and
953 N_WARNING are the same except for the N_EXT bit, so just use their
954 values alone, rather than OR-ing them with N_EXT.
956 Fri Sep 20 12:27:55 1991 Stu Grossman (grossman at cygnus.com)
958 * mipsread.c (parse_lines): Deal with negative extended line
961 * c-exp.y, m2-exp.y: #define yyerrflag and yynerrs to avoid
962 global symbol conflicts.
964 Fri Sep 20 02:28:15 1991 John Gilmore (gnu at cygnus.com)
966 * .gdbinit: Move 'set complaints' to top, so it runs even in
967 case we aren't debugging GDB.
968 * language.c (_initialize_language): Fix type check and range
969 check documentation strings.
970 * utils.c (!HAVE_VPRINTF): Define vfprintf as a function, so
971 language.c can use it. (Though language.c should really not be
972 handling warnings/errors the way it does, FIXME.)
973 * symtab.c (lookup_primitive_type): const lint.
975 Bugfix from Peter Schauer:
976 * source.c (lines_to_list): Make signed, to avoid comparison
977 going unsigned and complaining that -3 is too high for 21 lines.
978 * stack.c (lines_to_list): Ditto.
980 Thu Sep 19 23:33:41 1991 John Gilmore (gnu at cygnus.com)
982 * Makefile.in (HFILES): Add minimon.h.
983 (VERSION): Roll version number to 4.0.95.
984 (gdb.tar.Z, make-proto-gdb.dir, setup-to-dist, gdb-XXX.tar.Z):
985 New rules for building distributions. Normal distribution
986 is built by doing `make -f Makefile.in gdb.tar.Z' in the directory
987 one level up from here; it calls make-proto-gdb.dir to build a
988 directory `proto-gdb' which is an image of the release. The old
989 `gdb.tar.Z' rule still works too.
990 * config.sub, configure: Roll in latest from ..
992 Thu Sep 19 17:41:24 1991 Roland H. Pesch (pesch at cygnus.com)
994 * doc/gdbint.texinfo: Reorder contents; reorganize new-host,
995 new-target, and new-config chapters; fix minor typos; come closer
996 to usual GNU markup conventions for @file @samp @code @var.
998 Thu Sep 19 17:04:12 1991 Per Bothner (bothner at cygnus.com)
1000 Patches from Peter Schauer <pes@regent.e-technik.tu-muenchen.de>:
1001 * mipsread.c (parse_partial_symbols): Enter the name of all
1002 structs/unions... into the psymtab so we can access them if the
1003 symtab is not read in.
1004 * mips-tdep.c: Remove some unneeded #includes.
1005 * xconfig/dec3100: Add HAVE_STRSTR.

1017 Wed Sep 18 15:55:51 1991 John Gilmore (gnu at cygnus.com)
1019 Merge multiple-language support, and partial Modula-2 support,
1020 from Andrew Beers <beers@cs.buffalo.edu>.
1022 * i387-tdep.c: New file, consolidates most 80387 support,

1042 (process_coff_symbol): #if 0'd for functions and params as above.
1043 (read_enum_type): Recognize Modula-2 BOOLEAN.
1044 * symtab.c (add_param_to_type): #if 0'd function to add a

1080 TYPE_CODE_BOOL and TYPE_CODE_CHAR.
1082 * expression.h (enum exp_opcode): Add Modula-2 specific opcodes.

1116 Tue Sep 17 08:37:41 1991 John Gilmore (gnu at cygint.cygnus.com)
1118 Add Andrew Beers' changes for Modula-2 support. His ChangeLog
1119 entries are enclosed herein. Not all of these changes
1120 have been merged into the master GDB sources -- check the
1121 ChangeLog above here for the merge log.
1123 Mon Jun 3 17:05:45 EDT 1991
1125 m2-exp.y Created. Tested outside of GDB for a few days. Proper
1126 operators were added, C specific operators and tokens
1127 removed. yylex() revamped to some extent. Still things
1128 missing from the grammar, such as sets.
1129 Tested for two weeks in GDB v3.5.
1131 Tue Jun 11 17:23:48 EDT 1991
1133 m2-exp.y Added boolean constants TRUE and FALSE to the grammar
1134 so they are built-in. Sort of a hack.
1136 Fri Jun 14 12:53:51 EDT 1991
1138 m2-exp.y Added range checking for numeric constants. Any numeric
1139 constant is assumed to be of builtin type INTEGER unless:
1140 (1) it is octal or hexadecimal, in which case it is a
1141 CARDINAL; (2) it is too big to fit into an INTEGER, in
1142 which case it is a CARDINAL.
1143 eval.c Added simple range checking for +, -, and * on integers.
1144 Doesn't work very well for *, since 6 * 1,000,000,000 =
1145 1,705,032,704, which fails the simple test of result >=
1146 first_operand, no matter in what order the operands are.
1148 Tue Jun 18 14:11:30 EDT 1991
1150 Broke the parser into parts, one containing the C grammar and the other
1151 containing code to be shared by all of the grammars.
1153 The following files no longer exist:
1158 The following files were added:
1160 c-exp.y (The C grammar)
1161 m2-exp.y (The Modula-2 grammar)
1162 parser-code.c (Code that is shared by the above grammar)
1166 Makefile.dist Changed to reflect the above dependencies. NOTE: It is
1167 now necessary to use the Bison compiler compiler, since it
1168 will generate function/variable prefixes other than yy.
1170 Tue Jun 18 16:47:49 EDT 1991
1172 symtab.[ch] Added the external variable working_lang, than holds the
1173 value of the current working language.
1174 Added the ennumerated type language_mode, with the values
1175 language_auto and language_manual, the former meaning that
1176 GDB sets working_lang as needed, and the latter meaning
1177 that the value of working_lang is totally under user
1179 symtab.[ch] Added the Modula-2 pervasive types INTEGER, CARDINAL,
1180 REAL, BOOLEAN and CHAR. Also added the type codes
1181 TYPE_CODE_BOOL and TYPE_CODE_CHAR.
1182 utils.c Added set_language_command and show_language_command to
1183 implement the GDB support commands "set language" and
1185 expression.h A number of identifiers were added to the type exp_opcode
1186 to facilitate Modula-2 builtin functions, integer
1187 division, and array indexing.
1189 Wed Jun 19 13:25:58 EDT 1991
1191 language.h Added the macro STRICT_TYPE, which evaluates to non-zero
1192 if the language specified by working_lang requires the use
1193 of strict typing of expressions. Eventually, even this
1194 will be able to be changed by the user.
1195 Added the macro RANGE_CHECK, which evaluates to non-zero
1196 if the language specified by working_lang requires the
1197 checking of a value against the domain of its type.
1198 Eventually, even this will be able to be changed by the
1200 language.[ch] Predicates involving types (simple_type, ordered_type,
1201 same_type, integral_type, numeric_type, character_type,
1202 boolean_type, float_type) are added. These predicates are
1203 based on the current value of working_lang, and are handy
1206 Wed Jun 19 15:39:34 EDT 1991
1208 eval.c Added the function type_array_rank which computes the rank
1210 valarith.c Added the funtion value_bool, which when given a integer
1211 value.h value (ie. struct value *) as an argument, it returns a
1212 boolean value (ie. struct value *) true if that integer
1213 is non-zero, and a boolean value false otherwise.
1214 valprint.c Added cases for TYPE_CODE_BOOL, so Modula-2 BOOLEAN values
1215 will print out properly.
1217 Wed Jun 19 16:36:34 EDT 1991
1219 valops.c Added the function value_capitalize, which returns it
1220 value.h argument capitalized if its argument is a lowercase
1221 letter, or the argument unchanged if its argument is not a
1223 valarith.c Added the function range_check_p, which returns non-zero
1224 value.h if its value argument is between the integral bounds upper
1226 Added the function range_check_enum_p, which makes sure
1227 that its value argument is a valid member of the domain of
1229 Added the function range_check_range_p, which makes sure
1230 its value argument lies between the upper and lower bounds
1231 of its type argument, which must be a ranged type.
1232 Added the function check_array_index, which range and type
1233 checks an index of an array.
1234 Added the function value_multi_subscript, which computes
1235 array[idx1,idx2...idxN], given a value array and an array
1236 of values representing indicies.
1237 values.c Changed value_from_long to work with TYPE_CODE_CHAR and
1238 unpack_long to work with TYPE_CODE_BOOL and
1241 Wed Jun 19 18:04:08 EDT 1991
1243 symtab.c Stored pervasive types in a structure and make
1244 lookup_pervasive_type() a lookup function that was based
1245 on working_lang. If lookup_pervasive_type() returned
1246 non-zero, then that value was returned (a fix, since
1247 before it simply wouldn't return the pervasive type.)
1248 language.h Added the macro CAST_IS_CONVERSION, which evaluates to
1249 non-zero if the language specified by working_lang means
1250 "conversion" when it says "cast".
1251 valops.c Added the function value_real_cast(), which performs a
1252 value.h *cast*, not a *conversion*, which is what value_cast()
1253 does when it can. In particular,
1254 value_cast(<float_type>,4) = 4.0, while
1255 value_real_cast(<float_type>,4) = some mess.
1256 eval.c Modula-2 builtin functions implemented: ABS, CAP, CHR,
1257 parser-code.c FLOAT, HIGH, MAX, MIN, ODD, ORD, TRUNC, and VAL.
1258 expression.h Added macros MAX_OF_TYPE and MIN_OF_TYPE to work with MAX
1259 and MIN on integral types. *NOTE*: These are currently
1260 hardcoded to work only if there are 8 bits per storage
1262 eval.c Made logical functions call value_bool to return a
1263 properly typed boolean value, based on working_lang.
1265 Thu Jun 20 11:55:27 EDT 1991
1267 valprint.c Types now print out in a Modula-2 fashion. This works for
1268 the cases when the type is printed out step-by-step, that
1269 is, it doesn't work when the name of a structured type
1270 (which includes the keyword "struct", etc.) is simply
1272 FIXME: Perhaps this is bad. Parts of it seem to kludgey,
1273 since type specifications in C and Modula-2 are very
1274 different. The C printing of a type is very recursive,
1275 whereas in Modula-2 it is generally very simple. C has
1276 type prefixes and suffixes, which have no real analogue in
1277 Modula-2. Maybe type_print() should call a language
1278 specific type printer. This is also advantageous if we
1279 compile GDB to exclude some of the languages. We'll just
1280 leave those functions out.
1282 Thu Jun 20 16:57:10 EDT 1991
1284 dbxread.c When reading the complete symbol table in (via
1285 psymtab_to_symtab()), the number and types of function
1286 arguments are added to a function type. define_symbol()
1287 calls add_param_to_type() to accomplish this.
1288 Assumption: when we come across a function definition
1289 (N_FUN symbol with an 'f' or 'F' in the name), its
1290 arguments will appear before another function definition.
1291 When a function is found, a pointer to its type is placed
1292 in the global in_function_type. Changes that
1293 add_param_to_type() makes are to this global.
1294 valprint.c The type of a function now includes (for Modula-2) the
1295 types of its parameters.
1296 eval.c Type checking and a check for the proper number of
1297 arguments is now done for function calls. Not sure of the
1298 impact this has on C++ member function yet.
1300 Thu Jun 20 19:58:48 EDT 1991
1302 valprint.c Rewrote the type printer. Broke it into two language
1303 specific parts, adding the functions type_print_m2() and
1305 An unfortunate consequence is this: if you debugging a C
1306 program in Modula-2 mode (why?), info types does not work
1307 well with regular expressions, since the types are printed
1308 out in Modula-2 terminology, but stored in C terminology.
1309 language.[ch] Added the functions new_type_last(), type_keyword(), and
1310 type_sep() to aid in the printing of typedefs.
1311 symtab.c Made the printing of typedefs as language independent as
1312 possible through calls to new_type_last(), type_keyword(),
1315 Fri Jun 21 11:50:26 EDT 1991
1317 dbxread.c Check all incoming ennumerated types. If it looks like
1318 Modula-2's BOOLEAN type, then change the type_code of the
1319 type to TYPE_CODE_BOOL so we can process it as a boolean
1321 valprint.c Replaced some of the 0x%x with calls to sprintf and
1322 hexformat() in val_print().
1323 language.[ch] Added the function hex_to_string(), which converts its
1324 integral argument to a hexadecimal number (format is
1325 language based) and returns the result as a string.
1327 Mon Jun 24 12:25:07 EDT 1991
1329 valprint.c Some functions call type_print_1() directly, instead of
1330 value.h using type_print(), so they can specify where (column) to
1331 print things. Since type_print() takes care of language
1332 dependence, that needs to be called first. Added a
1333 parameter depth to type_print() (so it is now like
1334 type_print_1). Changed type_print to type_print_at, and
1335 made type_print a macro that passes a depth argument of
1337 symmisc.c Changed all calls to type_print_1 to calls to
1339 Makefile.dist Made it possible to build GDB for a specific set of
1340 depend languages. Do this by passing a definition for the macro
1341 LANGS to make. LANGS should be a string containing a
1342 space-separated list of language names (ie. LANGS="c m2").
1343 The default is to build all languages. Note that grammar
1344 files must follow the naming convention of <lang>-exp.y.
1345 gdb.lang This holds the current value of the LANGS macro. It is
1346 examined every time make is called, and is updated if
1348 eval.c Added #ifdef _LANG_<lang> to these files.
1349 expread.c Still need to add them to dbxread.c and coffread.c.
1357 Mon Jun 24 16:33:11 EDT 1991
1359 language.[ch] Added the functions hexformat_pre() and
1360 hex_to_string_pre(), which take a prefix argument to
1361 include in the format string. Thus, hexformat_pre("08") will
1362 return "0x08x" (if the working language is language_c).
1363 Made hexformat() and hex_to_string() calls to the above
1364 with "" as the prefix argument.
1366 am29k-pinsn.c, arm-pinsn.c, breakpoint.c, convex-tdep.c, exec.c, core.c,
1367 dbxread.c, i386-pinsn.c, i386-stub.c, i386-xdep.c, i960-pinsn.c,
1368 infcmd.c, inflow.c, m68k-pinsn.c, m68k-stub.c, m88k-pinsn.c,
1369 mips-pinsn.c, mips-tdep.c, ns32k-pinsn.c, printcmd.c, pyr-pinsn.c,
1370 pyr-tdep.c, pyr-xdep.c, remote-vx.c, remote.c, solib.c, source.c,
1371 stack.c, sun386-xdep.c, symfile.c, symm-xdep.c, symmisc.c, tahoe-pinsn.c,
1372 valprint.c, vax-pinsn.c
1374 Changed all occurences of 0x%[0-9]*l*x in printf format strings to
1375 calls to hexformat() and hex_to_string(). Format strings without
1376 the leading "0x" were ignored.
1378 depend Updated to take the above into account.
1381 Tue Jun 25 15:27:18 EDT 1991
1383 symtab.h Added the types range_mode_t, range_check_t, type_mode_t,
1384 and type_check_t to keep track of the current state of
1385 range and type checking.
1386 main.c Added the variables range_mode, range_check, type_mode,
1387 and type_check to record the current state of range and
1388 type checking. Added initialization code to main().
1389 language.h Changed the macros STRICT_TYPE and RANGE_CHECK to examine
1390 the above variables.
1393 Tue Jun 25 17:57:08 EDT 1991
1395 dbxread.c process_one_symbol() updates the variable (enum language)
1396 source_lang based on the extension of the filename
1397 contained in the N_SO sybmol that started this symtab.
1398 When end_symtab() is called, the value of source_lang is
1399 put into the language field.
1400 stack.c select_frame() sets working_lang (and possibly type_check
1401 and range_check) to the language field of the symtab
1402 associated with the frame that is selected if working_mode
1403 is language_auto. If working_mode is language_manual, a
1404 warning is printed and working_lang is not set.
1405 language.c Added the function set_type_range(), which sets the value of
1406 type_check and range_check (if their modes call for
1407 automatic setting) based on the current value of
1408 working_lang. A non-zero argument will cause the current
1409 settings to be output.
1412 Wed Jun 26 14:51:40 EDT 1991
1414 eval.c Added range checks on assignment.
1415 m2-exp.y Added the grammar for sets to the language. Currently,
1416 these do not do anything except print an error message.
1418 Wed Jun 26 17:01:04 EDT 1991
1420 m2-exp.y Added the ability for parse_number() to parse negative
1421 numbers. A global flag is set upon encountering a unary
1422 minus. This was done to make, for example, 1 parse as a
1423 CARDINAL, and not as an integer, per Wirth's examples in
1424 Programming in Modula-2 ed.4.
1425 valprint.c Added support for "set radix 2" by then setting
1426 output_format to 't'.
1427 eval.c Implemented range checking on subrange types. Added calls
1428 to range_check_range_p for BINOP_ASSIGN and BINOP_VAL.
1429 Implemented MIN and MAX for ennumerated types. The
1430 minimum value of an ennumerated type is defined by Wirth
1431 as the first identifier, and the maximum as the last.
1432 m2-exp.y Made octal numbers ending with "B" be characters and those
1433 ending with "C" be numbers, per Wirth's book. (p. 34)
1435 Thu Jun 27 14:11:52 EDT 1991
1437 stack.c select_frame() now only sets working_lang, it does not
1438 notify the user. If working_mode is language_manual, then
1439 a warning is issued once.
1440 main.c At the end of each call to execute_command(), working_lang
1441 is checked against the local static (enum language)
1442 current. If they differ and working_mode is
1443 language_auto, the new settings of language, type and
1444 range checking are printed out.
1445 stack.c Modified frame_info() to include the language of the
1446 current frame in the output of "info frame".
1447 language.[ch] Added the function language_str() which returns the name
1448 of the current language.
1450 Fri Jun 28 15:33:14 EDT 1991
1452 m2-exp.y Added the built-in procedures INC, INCL, DEC, and DECL to
1453 the language. INCL and DECL currently cause an error,
1454 since sets are not implemented yet. INC and DEC are
1455 implemented as PREINCREMENT/PREDECREMENT with one
1456 argument, and as ASSIGN_MODIFY with two arguments.
1457 eval.c Added type checking to the above cases.
1458 value.h Added not_lval_constant to the lval_type ennumerated type.
1459 not_lval_constant means that the value is a constant
1460 value; that is 3 or 'a' or TRUE, not as in a constant
1461 identifier. This is used to help coerce numbers such as 3
1462 to either signed or unsigned numbers.
1463 valops.c Added the function value_coerce_constants() which coerces
1464 constant integers as following: if one is a constant and
1465 the other is not, the constant's type is set to the type
1466 of the other argument. If both are constants and one is
1467 signed, the other is converted to a signed constant.
1469 Sat Jun 29 17:26:29 EDT 1991
1471 valarith.c Added a better range checker. It now checks range
1472 (successfully) on integral operations [+-] (signed and
1473 unsigned) for any C sized type. Still does not work well
1474 for multiplication.)
1475 int_in_size() returns an integer that is coerced to fit into
1476 specified number of bytes.
1478 Mon Jul 1 13:04:14 EDT 1991
1480 language.[ch] Added the function binop_result_type(), which returns the
1481 builtin (struct type *) type that would be the result of a
1482 binop on the two values V1 and V2.
1484 Wed Jul 3 19:22:53 EDT 1991
1486 source.c Extended source_info() to include the source language in
1487 the output from "info source".
1489 Fri Jul 5 13:48:52 EDT 1991
1491 utils.c Moved the support functions for the GDB set/show commands
1492 dealing with language into language.c.
1493 language.c Added the function language_info(), which displays info
1494 about the current working language, type and range check
1495 settings. Called via the GDB command "info language".
1496 Added an initialization routine _initialize_language(),
1497 that sets defaults for the language, type and range
1498 variables and sets up the new GDB commands.
1499 main.c Language setup moved to language.c.
1502 Mon Jul 8 10:10:22 EDT 1991
1504 valarith.c Debugged the range checker for arithmetic. Still does not
1505 work for multiplication very well.
1507 Mon Jul 8 12:40:37 EDT 1991
1509 language.[ch] Added the function value_true() which returns non-zero if
1510 its argument represents a boolean true value.
1511 breakpoint.c Changed breakpoint_cond_eval() to call value_true() to
1512 check the truth of an expression.
1514 Thu Jul 11 12:51:34 EDT 1991
1516 language.[ch] Added the predicate structured_type(), which returns
1517 non-zero if the argument is a structured type.
1518 Added the predicate pointer_type(), which returns non-zero
1519 if the argument is a pointer type.
1520 eval.c Added the ability to do addition and substraction on
1521 pointers and integers. This case simply bypasses the
1524 Thu Jul 11 14:41:42 EDT 1991
1527 Added the symbol N_DEFD (0x4a) which is a definition
1528 module dependency that is used by the GNU Modula-2
1529 compiler and the linker. It is not important to GDB,
1530 except that [dbx|coff|mips]read.c should ignore these
1533 Fri Jul 12 16:07:00 EDT 1991
1535 valprint.c Changed the TYPE_LENGTH(type) >= 0 to TYPE_LENGTH(type) >
1536 0 in val_print(). Also added statements to the else part
1537 to coerce type (argument to val_print) to a pointer type
1538 if it is an "array of unspecified length".
1539 valops.c Added the function value_m2_string(), which returns a
1540 (value) value which is a constant string, whose type is
1541 (ARRAY [0..n] OF CHAR). The length field of the type
1542 structure is set to zero, so it will be interpreted as an
1543 "array of unspecified length".
1544 stack.c Moved the language/frame mismatch check to
1545 main.c:execute_command().
1546 main.c The working language is recorded each time
1547 execute_command() is executed. If working lang has
1548 changed during its execution, then the new
1549 language/type/range info is printed out for the user. If
1550 the working language does not match the language of the
1551 frame, a warning is issued.
1553 Sat Jul 13 16:16:39 EDT 1991
1555 eval.c Moved all the type-checking stuff for operators to
1556 language.[ch] language.c. This is so we can keep language-specific
1557 stuff (like for what type operators are defined) in
1559 language.[ch] Added the function binop_type_check(), which checks to see
1560 if its two (value) arguments are type-compatible with its
1561 opcode argument. The opcode should represent an operation
1562 involving an operator. Also added the macro function
1563 unop_type_check, which calls binop_type_check with a
1564 NULL second argument.
1565 expprint.c Added Modula-2 operators to the op_print_tab, so info
1566 expression.h break works correctly. Also added "op_string", which
1567 returns the string corresponding to the (enum exp_opcode)
1568 opcode that is its argument.
1571 Sat Jul 13 18:26:18 EDT 1991
1573 coffread.c Added code to record the type of function arguments with
1574 each paricular function. Code is very similar to that
1576 dbxread.c Moved add_param_to_type() to symtab.c
1577 symtab.[ch] Added function add_param_to_type() from dbxread.c
1579 *** NOTE: The above additions have not been tested.
1581 Mon Jul 15 12:50:47 EDT 1991
1583 langauge.[ch] Added the functions type_error and range_error, which work
1584 like error() except if the type/range mode is set to
1585 *_mode_warn, then they do not do a return_to_top_level(),
1586 but merely print a warning.
1587 Also changed [set|show]_[type|range]_command() to support
1588 the new "warn" feature.
1590 Thu Jul 18 17:50:54 EDT 1991
1592 mipsread.c Added code to record the type of function arguments with
1593 each particular function. Code is very similar to that
1596 *** NOTE: The above additions have not been tested.
1598 Fri Jul 19 11:19:10 EDT 1991
1600 defs.h Added macros MAX_OF_SIZE, MIN_OF_SIZE, UMAX_OF_SIZE, and
1601 UMIN_OF_SIZE, which when given a size of a numeric type,
1602 return the maximum and minimum value it can hold. UMAX...
1603 and UMIN... return the result for unsigned types.
1604 symtab.h Added the macros MAX_OF_TYPE and MIN_OF_TYPE to operate on
1605 struct types. They call above macros.
1606 dbxread.c Renamed the MAX and MIN_OF_TYPE macros to ..._OF_CTYPE to
1607 avoid a name conlict with the above.
1608 c-exp.y Added range checking on numeric constants in
1609 parse_number() for completeness.
1610 valarith.c Made binop_user_defined_p() and unop_user_defined_p()
1611 return 0 if working_lang is not language_c.
1613 Thu Aug 8 14:17:22 EDT 1991
1617 breakpoint.c Documentation strings of some commands changed to
1618 eliminate the references to the C language where
1621 Tue Aug 13 15:48:03 EDT 1991
1623 m2-exp.y Added qualified identifiers to the grammar. The semantics
1624 are slightly different from those of the GDB operator ::
1626 m2-exp.y Added a rule to each grammar of the form: start ::= exp |
1627 type_exp, where type_exp is any valid type expression.
1629 eval.c Added the opcode OP_TYPE, and an error case in eval.c.
1630 printcmd.c Modified ptype_command() so it actually parses the input
1631 (necessary for type expressions with scope qualifiers).
1632 Added the function ptype_eval() which expects an
1633 expression composed of one OP_TYPE element.
1634 *.[ch] Replaced all occurences of parse_c_expression with
1636 *.[ch] Replaced all occurences of parse_c_1 with parse_exp_1
1638 [End of ChangeLog entries from Andrew Beers for Modula-2 support.]
1640 Mon Sep 16 17:19:46 1991 John Gilmore (gnu at cygnus.com)
1642 Small fixes from Peter Schauer:
1644 * infrun.c (child_attach): Lint.
1645 * solib.c (find_solib): Handle shared libs version 2.
1647 Small fixes from David Wood:
1649 * xm-ultra3.h (SYS_SIGLIST_MISSING): Typo.
1653 * remote-vx.c: Move <stdio.h> to top, for FILE. Fix from
1654 John S <basrai%kanga.dnet@c3po.sm-alc.af.mil>.
1656 * utils.c (wrap_here): Avoid wrap action of fputs_filtered if
1657 chars_per_line is at maximum (user typed `set width 0'). Fix
1658 from Andreas Schwab <schwab@ls5.informatik.uni-dortmund.de>.
1660 Tue Sep 17 17:31:04 1991 Stu Grossman (grossman at cygnus.com)
1662 * coredep.c: include ptrace.h where necessary.
1663 * mipsread.c(parse_lines): fix unsigned char problem that was
1664 messing up line numbers on SGI's and possibly other MIPS based
1666 * infrun.c (child_create_inferior): use better test to check
1667 return val from setpgrp().
1668 * tm-irix3.h, xm-irix3.h, tconfig/irix3, xconfig/irix3: add these
1669 for sgi/irix support.
1671 Wed Sep 18 04:33:31 1991 Per Bothner (bothner at cygnus.com)
1673 * mipsread.c (parse_symbol): Put non-static procedures
1674 in the global block.
1676 Fri Sep 13 00:14:52 1991 John Gilmore (gnu at cygnus.com)
1678 Patch together `text_start' and `text_end' for 29K port.
1680 * exec.c (exec_command): If NEED_TEXT_START_END, define the
1681 variables and set them based on the exec file.
1682 * am29k-tdep.c: declare text_start.
1683 * valops.c (call_function_by_hand): declare text_end.
1685 * inferior.h: Eliminate CANNOT_EXECUTE_STACK in favor of
1686 defining CALL_DUMMY_LOCATION as BEFORE_TEXT_END. This is
1687 because machines that do this will also have to know to
1688 set NEED_TEXT_START_END. Besides, it was a redundant way to
1690 * tm-29k.h, tm-convex.h, tm-np1.h: Eliminate
1691 CANNOT_EXECUTE_STACK, define CALL_DUMMY_LOCATION and
1692 NEED_TEXT_START_END.
1694 Thu Sep 12 00:22:24 1991 John Gilmore (gnu at cygint.cygnus.com)
1696 AMD 29000 changes from David Wood <wood@david.ultra.nyu.edu>:
1698 * Makefile.in (CLIBS): Put XM_CLIBS and TM_CLIBS at end.
1699 Pass MUNCH_DEFINE to munch whenever we run it.
1700 * am29k-pinsn.c (print_insn): Handle NOP specially. Avoid %#x
1701 format string; use 0x%x instead.
1702 * am29k-tdep.c: Use DUMMY_SAVE_GREGS and RETURN_REGNUM.
1703 * ultra-xdep.c, xm-ultra.h: New files for Ultracomputer host system.
1704 * xm-rtbsd.h: New host support for RT/PC running BSD Unix.
1705 * inflow.c: Handle `short' process group IDs.
1706 * infptrace.c (fetch_register): Support CANNOT_FETCH_REGISTER,
1707 and check for ptrace errors.
1708 * coffread.c (SDB_REG_TO_REGNUM): Define if not already.
1709 (coff_symfile_init): Initialize text_bfd_scnum.
1710 (read_coff_symtab): Use it to find the text [and absolute?] sections.
1711 * ../config.sub: Add vendor nyu and os "sym[1-9]*".
1712 * configure.in: Add hosts rtpc-*-* and a29k-*-*.
1713 Merge target arm case with other "easy" cases. Add target
1714 cases a29k-*-none (rehack of am29k), a29k-*-kern (remote to
1715 Ultracomputer kernel), and a29k-*-sym1 (ultracomputer OS's user
1717 * minimon.h, remote-adapt.c, remote-mm.c: Add.
1718 * munch: Cope with RT/PC putting fns in data segment.
1719 Restore ability to override `nm' by specifying MUNCH_NM.
1720 * xconfig/rtbsd, xconfig/ultra3: New host systems.
1721 * tconfig/a29k: Rename from tconfig/am29k. Add remote-mm
1722 and remote-adapt. Remove encapsulated coff #define's (the
1723 support should go in BFD, and gdb shouldn't know or care).
1724 * tconfig/a29k-kern: Same, but for remote kernel debugging.
1725 * tconfig/ultra3: For debugging user processes on Ultra3/Sym1.
1726 * tm-29k.h: Update BADMAG (though it should go away).
1727 Allow the register definitions to be overridden in another
1728 tm-file. Fix SR_REGNUM. Add a mess of _REGNUM's. Separate
1729 RETURN_REGNUM from GR96_REGNUM and DUMMY_SAVE_GREGS from
1730 DUMMY_SAVE_GR96, for handling kernel calling conventions
1731 that use GR64+ rather than GR96+.
1732 * tm-ultra3.h: New file, for use on Ultra3 Unix as well as for
1733 remote debugging of Ultra3 kernel. Includes tm-29k.h and
1734 overrides various things.
1736 * remote-mm.c (mm_attach, mm_wait): Handle attach like
1737 child_attach does, making a clean stop in the newly attached
1739 * remote-eb.c: Lint.
1741 * coffread.c: Make coffread independent of any particular
1742 variant of COFF. Avoid #include-ing any particular one except
1743 internalcoff.h. BFD now passes key values for symbol reading
1744 as part of its coff_data structure (LINESZ, SYMESZ, AUXESZ,
1745 and the symbol masks and shifts); use them.
1746 Remove obsolete end_of_text_addr.
1748 * exec.c: Remove unused include files.
1750 Wed Sep 11 19:38:44 1991 John Gilmore (gnu at cygint.cygnus.com)
1752 * Makefile.in (documentation targets): Pass $(M4).
1753 Bugfix from eggert@twinsun.com (Paul Eggert).
1755 * stack.c (down_silently_command): Check for stack existence.
1757 Tue Sep 10 23:08:29 1991 John Gilmore (gnu at cygint.cygnus.com)
1759 * Makefile.in (VERSION): Update to 4.0.3.
1761 Tue Sep 10 09:19:29 1991 John Gilmore (gnu at cygint.cygnus.com)
1763 * core.c (core_file_command): Print frame at coredump with
1764 its level number, by calling print_stack_frame.
1765 * frame.h: Add selected_frame_level, print_stack_frame.
1766 * frame.h, stack.c: Remove print_sel_frame, print_selected_frame.
1767 * convex-tdep.c, convex-xdep.c, infcmd.c, inflow.c, infrun.c:
1768 Change print_sel_frame and print_selected_frame callers to
1771 * dbxread.c (read_ofile_symtab): Avoid empty else clause.
1772 * symfile.c (free_named_symtabs): Ditto.
1773 * main.c (main): wrap_here needs an arg.
1774 * solib.c (find_solib): Avoid memory access if _DYNAMIC is zero.
1775 (solib_add): Avoid noise.
1776 (solib_create_inferior_hook): Lint.
1777 (sharedlibrary_command): Move dont_repeat to here.
1778 * utils.c (error): Call wrap_here to force buffered output.
1780 Small patches from Peter Schauer:
1782 * coffread.c (start_symtab): Free any existing line_vector before
1784 (read_coff_symtab): Ditto for type_vector.
1786 * source.c (lines_to_list): New variable, replacing function.
1787 (all uses): Use as variable.
1788 (_initialize_source): Add 'set listsize' and 'show listsize'.
1789 * utils.c (lines_to_list): Remove function.
1790 * stack.c (print_frame_info): Use as variable.
1791 * defs.h (lines_to_list): Remove declaration.
1793 Mon Sep 9 13:45:57 1991 John Gilmore (gnu at cygint.cygnus.com)
1795 * breakpoint.c (insert_breakpoints): Restore warning about
1796 the program might be running in another process, but only for
1797 systems with this brain death (#ifdef ONE_PROCESS_WRITETEXT).
1798 * xm-hp300bsd.h, xm-mips.h, xm-vax.h: Define it.
1800 * utils.c (error): if error_pre_print is set, print the string
1802 * main.c (main, print_gnu_advertisement, print_gdb_version):
1803 Reformat legalese so it always prints, but acts as an "I'm here"
1804 message while symbols are being read. If any errors occur,
1805 print a few newlines to set off the message and start it at the
1806 left margin. Remove mention of "help" command, and don't yak
1807 about symbol reading.
1808 (catch_errors): Error string is now printed first in case of
1810 * command.c (undef_cmd_error, lookup_cmd): On undefined command,
1811 suggest the "help" command.
1813 * Makefile.in (VERSION): Set to 4.0.2.
1815 Thu Sep 5 23:49:48 1991 John Gilmore (gnu at cygint.cygnus.com)
1817 * .gdbinit: Remove useless "rr" command. Set complaints
1818 to 1 for people debugging gdb.
1820 * breakpoint.c, remote-vx.c: Reword strings printed by
1821 catch_errors callers.
1823 Wed Sep 4 11:07:50 1991 John Gilmore (gnu at cygint.cygnus.com)
1825 * WHATS.NEW: "history write -> history save". Doc "write on/off".
1826 (Fix from kenc@viewlogic.com.)
1828 Fix some infrastructure to be able to cope with host and target
1829 machines with different sized basic types (ints, ptrs, etc).
1830 (Idea from pierre@la.tce.com (Pierre Willard).)
1832 * values.c (value_from_longest): Rename from value_from_long.
1833 Handle pointer types as well as integers, so that targets with
1834 different pointer sizes from the host can be accomodated.
1835 * breakpoint.c, convex-tdep.c, eval.c, expprint.c, printcmd.c,
1836 valarith.c, valops.c, valprint.c, value.h, values.c: Rename
1837 uses of value_from_long to value_from_longest.
1838 * eval.c, findvar.c, printcmd.c, valarith.c, valops.c: Pass
1839 the correct pointer type to value_from_long{est}.
1841 * doc/gdb.texinfo ($_, $__): Describe types of these variables.
1843 * remote-vx.c: Remove obsolete code for calling functions via
1844 vxworks kludge interface (it referenced value_from_long).
1846 * valops.c (value_string): Find malloc with lookup_misc_func, not
1849 Tue Sep 3 18:37:46 1991 John Gilmore (gnu at cygint.cygnus.com)
1851 Make writing to files work properly. (Fixes to BFD are also needed.)
1853 * core.c (core_open): Open file ourselves, read or r/w, depending on
1854 write_files. Use bfd_fdopenr.
1855 * gdbcore.h (write_files): New variable.
1856 * exec.c (write_files): Define variable, add set&show for it.
1857 (exec_file_command): Use write_files to open for read or r/write.
1859 Make shared library reading happen automatically. These changes
1860 are mostly from Peter Schauer <pes@regent.e-technik.tu-muenchen.de>.
1862 * inferior.h (stop_soon_quietly): Add to exported variables.
1863 * infrun.c (child_create_inferior): call solib hook, if defined.
1864 (child_attach): call solib hook, if defined.
1865 * solib.c: Include inferior.h. Add from_tty to so_list as kludge.
1866 (find_solib): Use lookup_misc_func rather than hand-rolled.
1867 (symbol_add_stub): New stub for catch_errors.
1868 (solib_add): Avoid output if !from_tty. Catch errors rather
1869 than just calling symbol_file_add and bombing.
1870 (solib_create_inferior_hook): Interface with the target process
1871 to let it read and alloc shared libs, then figure out what it did.
1873 * core.c (validate_files): Fix typo, soften warning.
1874 (Fix from Hiroto Kagotani <kagotani@cs.titech.ac.jp>.)
1876 * utils.c (fputs_demangled): Avoid duplicate printing if
1877 demangling is off. (Fix from J.T. Conklin <jtc@cayenne.com>.)
1879 * infrun.c (proceed): Cast -1 to (CORE_ADDR) before comparing.
1880 (Fix from pierre@la.tce.com (Pierre Willard).)
1882 * main.c (catch_errors): Change argument to a char * from an int,
1883 since a char * can point to a struct full of glop, but an int
1884 is not guaranteed to be able to hold a pointer.
1885 * breakpoint.c (breakpoint_cond_eval, bpstat_stop_status,
1886 breakpoint_re_set_one, breakpoint_re_set): Adapt.
1887 * core.c (core_open, solib_add_stub): Adapt.
1888 * remote-vx.c (symbol_stub, add_symbol_stub, callers): Adapt.
1890 Wed Aug 28 18:18:05 1991 John Gilmore (gnu at cygint.cygnus.com)
1892 * Makefile.in: Update VERSION to 4.0.1. Evade GNU Make bug
1893 by adding .NOEXPORT target.
1895 Fri Aug 23 17:14:25 1991 John Gilmore (gnu at cygint.cygnus.com)
1899 * Makefile.in (VERSION): Roll to 4.0.
1900 (gdb.tar.Z): Make refcard.ps as well, for shipment.
1902 Fri Aug 23 14:07:09 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1904 * doc/gdb.texinfo: minor rewordings, crossref to ptype from print,
1907 * doc/Makefile, Makefile.in: generate "gdb-all.texi" rather than
1910 * doc/rdl-apps.texi: renamed from rdl-apps.texinfo
1912 * Makefile.in, doc/Makefile, doc/.Sanitize, doc/gdb.texinfo:
1913 reflect above name change
1915 * WHATS.NEW: correct pointer to refcard.
1917 * doc/gdb.texinfo: update New Features, Installing
1919 * doc/gdbint.texinfo: add short description of configure +template
1921 Fri Aug 23 11:46:08 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1923 * doc/gdb.texinfo: update, fix bugs in "Installing" appendix
1925 Fri Aug 23 01:02:00 1991 John Gilmore (gnu at cygint.cygnus.com)
1927 * Makefile.in: Add config.sub, make doc/rdl-apps.texinfo for
1928 tar file, add dependencies for referenced doc files.
1930 Thu Aug 22 22:17:06 1991 Stu Grossman (grossman at cygint.cygnus.com)
1932 * coffread.c, symfile.c, stack.c: saberized.
1934 Thu Aug 22 16:20:27 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1936 * doc/refcard.tex: permuted Essential Commands sec
1938 * doc/gdb.texinfo: new C++ chapter; revised installation appendix;
1940 set/show symbol-reloading
1941 default set complaints 0
1943 RET-repeat disabled after prompted long displays
1944 processID (attach) interpretation of 2nd GDB cmdline arg
1946 Thu Aug 22 14:05:47 1991 Stu Grossman (grossman at cygint.cygnus.com)
1948 * expread.y, coffread.c, dbxread.c, target.c, mem-break.c,
1949 cplus-dem.c, values.c, valprint.c, symfile.c, remote.c,
1950 breakpoint.c, main.c: lint.
1952 Thu Aug 22 02:02:26 1991 John Gilmore (gnu at cygint.cygnus.com)
1954 Install new configuration scheme for GDB and friends.
1956 * config.sub: Translate ordinary names to three-part names.
1957 * configure: Use three-part names internally.
1958 * configure.in: Translate three-part names to filenames.
1960 * README, WHATS.NEW: Update for gdb-4.0.

1963 Wed Aug 21 18:21:09 1991 John Gilmore (gnu at cygint.cygnus.com)
1965 * infptrace.c (KERNEL_U_ADDR_BSD): Include a.out.gnu.h.
1966 * i960-tdep.c, m68k-tdep.c, sparc-tdep.c, tm-i960.h,
1967 tm-m68k.h, remote-nindy.c: Change ext_format_XXX structs
1968 to single structures rather than arrays; when passing
1969 their address, use &. This avoids trouble with bdead compilers.
1970 * mcheck.c: Don't include <stdlib.h>; just declare "void abort();"
1971 instead. This avoids portability headaches.
1972 * mips-tdep.c (mips_do_registers_info): Only print FP regs if
1974 * source.c (open_source_file): Avoid ANSI const bdeath by
1975 skipping declaration and then casting result value.
1976 * tm-hp300bsd.h: Clarify comment.
1977 * utils.c (strstr): Result is const char *; ANSI bdeath.
1978 * xm-hp300bsd.h: Define HOST_BYTE_ORDER. Redefine INT_MIN,
1979 since system include file defines it differently from "defs.h",
1980 though the two are equivalent for our purposes.
1981 * tconfig/hp300bsd: Add m68k-tdep.o.
1983 Tue Aug 20 16:01:11 1991 John Gilmore (gnu at cygint.cygnus.com)
1985 * tconfig/sun*4: Remove warnings about system assembler.
1987 Mon Aug 19 13:44:46 1991 John Gilmore (gnu at cygint.cygnus.com)
1989 * mcheck.c: Avoid warning about undeclared abort fn.
1990 * tm-sparc.h (PC_ADJUST): Avoid calling error() from this;
1991 it causes recursive calls to error() when used in cleanups.
1992 To do so requires that we make it a function, so we do.
1993 * sparc-tdep.c (sparc_pc_adjust): New implem of PC_ADJUST.
1994 * utils.c (do_cleanups): Remove the current cleanup from the
1995 chain *before* calling it, in case error() is called from it.
1996 The result won't be pretty, but won't be an infinite loop either.
1998 Mon Aug 19 00:41:04 1991 Michael Tiemann (tiemann at cygint.cygnus.com)
2000 * dbxread.c (read_struct_type): Grok anon structs for C++.
2001 (vb_name, vptr_name): Null terminate these strings.
2003 Fri Aug 16 08:31:03 1991 John Gilmore (gnu at cygint.cygnus.com)
2005 Minor bug fixes from BSD Net2 gdb:
2007 * blockframe.c (get_prev_frame_info): If FRAME_CHAIN_COMBINE
2008 returns 0, there is no previous frame.
2009 * breakpoint.c (commands_command): If !from_tty, don't call
2010 input_from_terminal_p().
2011 * dbxread.c (record_misc_function): Speed up slightly.
2012 (compare_psymbols): Ditto.
2013 * infcmd.c (do_registers_info): Take a second argument to
2014 determine whether to print float registers. "info registers"
2015 does not do so anymore. "info all-registers" does, now.
2016 * mips-tdep.c, pyr-tdep.c (xxx_do_registers_info): Take second
2018 * tm-mips.h, tm-pyr.h (DO_REGISTERS_INFO): Pass second arg.
2019 * inflow.c (initialize_inflow): Set tflags_ours correctly.
2023 * breakpoint.c (bpstat_do_actions): Use a cleanup to restore
2024 executing_breakpoint_commands if we are interrupted by error.
2025 * coffread.c (init_lineno): Avoid problem with zero-sized linetab
2026 versus malloc/free. From: john@labtam.labtam.oz.au (John Carey).
2027 * core.c (solib_add_stub, core_open): Call SOLIB_ADD inside a
2028 catch_errors() so we can setup the frame regardless of whether
2029 the shared libs work.
2030 * ieee-float.c (double_to_ieee_extended): Get exponent from
2031 right place in little-endian systems. From John Carey.
2033 Thu Aug 15 18:43:57 1991 John Gilmore (gnu at cygint.cygnus.com)
2035 * main.c: Remove unused terminating_signals and catch_termination().
2036 (long_options): Terminate with a zero element.
2037 [Bugfix from Atsuo Kawaguchi <atsuo@hark86.harl.hitachi.co.jp>.]
2038 (gdb_readline): Make call-compatible with readline.
2039 (init_signals): Improve comments re vfork vs. signal.
2041 * utils.c (prompt_for_continue): Use new gdb_readline().
2042 If we prompt for continuation, we don't let CR repeat the previous
2043 command, once we get back to a prompt. It's too easy to keep
2044 hitting CR, expecting "--more--" prompts, and have some long
2045 command start repeating on you.
2047 Tue Aug 13 16:17:56 1991 John Gilmore (gnu at cygint.cygnus.com)
2049 * blockframe.c (frameless_look_for_prologue): Speed up by
2050 calling SKIP_PROLOGUE_FRAMELESS_P if it's defined.
2051 * tm-sparc.h (SKIP_PROLOGUE, SKIP_PROLOGUE_FRAMELESS_P):
2052 Define two variants, one faster.
2053 * sparc-tdep.c (sparc_frame_chain): Use target_read_memory
2054 and return zero, rather than giving an error.
2055 (setup_arbitrary_frame): Initialize the PC in the new frame.
2056 (skip_prologue): Add a second arg saying whether we're just
2057 checking for a frameless function or not.
2059 * core.c (core_open, core_close, core_xfer_memory): Move
2060 section table pointers and bfd* into the target_ops.
2061 (core_open): Allow errors in shared lib reading, etc.
2062 (core_files_info): Describe shared library sections.
2064 * exec.c (exec_open, exec_close, exec_xfer_memory, xfer_memory,
2065 exec_files_info, set_section_command): Move section table
2066 pointers and bfd* into the target_ops.
2067 (add_to_section_table): Add BFD to section table.
2069 * target.c (target_xfer_memory, target_info): Pass target to
2070 xfer_memory and target_info functions.
2073 * gdbcore.h: Move struct section_table.
2074 * target.h: New home of struct section_table.
2076 * solib.c (solib_add): New argument is the target_ops whose
2077 section list is to be added to, if any. Reallocate the
2078 sections in that target to add any that come from shared libs.
2079 (throughout) so_sections renamed to sections.
2080 (solib_xfer_memory): Deleted.
2081 * tm-sunos.h (SOLIB_ADD): Add target argument.
2082 (SOLIB_XFER_MEMORY): Delete.
2084 * core.c, exec.c, inftarg.c, remote-eb.c, remote-nindy.c,
2085 remote-vx.c, remote.c, target.c, target.h: Remove add_syms vector
2086 from target_ops. It's the same on all targets. Add two section
2087 pointers to target_ops.
2089 * stack.c (find_relative_frame): Dump ancient algorithm for
2090 "down", just use handy "next" pointers.
2091 (frame_command): Don't error if there is no stack; let user
2094 * inflow.c (new_tty_prefork, new_tty): New prefork routine
2095 modifies static state in the parent process; new_tty itself
2096 runs in the child and modifies the child's file descriptors
2097 to match the saved static state.
2098 * infrun.c (child_create_inferior): Call new_tty_prefork,
2101 * infptrace.c (child_xfer_memory): Add ignored target arg.
2102 * remote-eb.c (eb_xfer_inferior_memory): ''
2103 * remote-nindy.c (nindy_xfer_inferior_memory): ''
2104 * remote-vx.c (vx_xfer_memory): ''
2105 * remote.c (remote_xfer_memory): ''. Rename from
2106 remote_xfer_inferior_memory.
2108 * main.c (main): Only try to attach "corefile" argument if
2109 it starts with a digit.
2111 * symfile.c (symbol_reloading): New "set/show" variable.
2112 (symbol_file_add): Shorten message about symbol reading.
2113 (add_symbol_file_command): Merge with add_syms_addr_command,
2114 since this should work on all targets now.
2115 (stop_whining): Default to zero, to shut up complaints
2116 about bad symbol tables on many systems.
2117 (free_named_symtabs): Just exit unless symbol_reloading.
2119 * xm-sun3os4.h, xm-sun4os4.h: Define BROKEN_LARGE_ALLOCA,
2120 and add comment explaining shared library screw.
2122 * source.c: #if defined => #ifdef.
2124 Thu Aug 8 12:23:19 1991 John Gilmore (gnu at cygint.cygnus.com)
2126 * doc/gdbint.texinfo: Improve doc on porting to new OS's.
2128 Tue Aug 6 17:16:15 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
2130 * doc/rdl-apps.texinfo: provide default readline-appendix finder
2131 (doc/Makefile knows how to make one for local config)
2133 * Makefile.in: use doc/Makefile for doc targets
2135 * doc/Makefile: GDB documentation now has its own Makefile
2136 doc/refcard.tex: renamed from "gdbrc.tex"
2137 doc/.Sanitize: add Makefile; recognize renamed refcard.tex
2138 doc/gdbint.texinfo: add markup in "Cleanups" chapter
2141 Fri Aug 2 00:13:06 1991 John Gilmore (gnu at cygint.cygnus.com)
2143 * values.c (baseclass_addr): When reading target memory, use the
2144 length of the basetype, not the upper type. We've only malloc'd
2145 enough space for the basetype, leading to errors in free().
2147 * expprint.c (print_subexp): Print UNOP_MEMVAL of an OP_LONG that
2148 ends up as a function specially, since we know the actual type of
2149 the pointed-to address. This (somewhat) fixes display of
2150 expressions that include misc_function_vector names. Try `cond 1
2151 !strcmp("a","b")' then `i b'.
2153 * infrun.c: Move DO_DEFERRED_STORES from proceed() to resume().
2154 The child can be proceeded from inside wait_for_inferior in
2155 evaluating breakpoint conditions, and DO_DEFERRED_STORES was
2156 getting skipped in that case.
2158 * expprint.c (print_subexp): Use filtered output, since the
2159 subroutines we call use it, otherwise the output is horribly
2160 mangled, since output of wrappable stuff comes out late.
2162 * Makefile.in: Bump VERSION to 3.98.1
2164 * infrun.c (child_create_process): Use execlp to find the
2165 shell to exec our target program. This requires some fiddling
2166 with `environ' since there is no execlpe().
2168 Thu Aug 1 15:35:17 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
2170 * Makefile.in, doc/gdbrc.tex, doc/rc-* (new files):
2171 Minor rearrangement of refcard permits two new make targets--
2172 gdbrc.dvi DVI output for refcard, using CM fonts
2173 gdbrc.ps PostScript refcard, using PS fonts
2175 Wed Jul 31 16:46:21 1991 John Gilmore (gnu at cygint.cygnus.com)
2179 * TODO, Projects, WHATS.NEW, README: Update for gdb-3.98.
2180 * Makefile.in (gdb-all.texinfo): Avoid touching file if M4 dies.
2182 Wed Jul 31 16:35:58 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
2184 * doc/gdb.texinfo: last changes for release.
2185 Minor typo and formatting fixes; incorporated most fixes remaining from
2186 filed mail commenting on earlier drafts.
2188 Added warnings: pipes don't work in run command;
2189 conditions are converse of assertions;
2190 step over fn without debug info goes to next fn;
2191 vars may have "wrong" values near fn entrance, exit
2193 Added example from Kingston on printing repeated nonadjacent values
2195 Added explicit mention that in Emacs gdb mode C-c and C-z are like
2196 shell mode for signals
2198 Renamed "Stepping and Continuing" to "Continuing and Stepping" so it
2199 doesn't sound so much like its parent "Stopping and Continuing"; also
2200 moved entries on continue to top of section, so they don't get lost.
2202 Improved installation directions in appendix, added manual formatting
2205 Tue Jul 30 17:26:39 1991 John Gilmore (gnu at cygint.cygnus.com)
2207 * configure.in: Remove xm.h and tm.h even if we aren't linking
2208 new ones, so "./configure sun4; ./configure none" does the right
2209 thing. Assume that alldeps.mak and depend are already built in
2210 srcdir, and avoid running "make" (particularly "make depend",
2211 which involves "gcc") from inside configure. Build Makefile
2212 directly rather than building Makefile.conf first.
2213 * configure: Regenerate with above changes.
2214 * Makefile.in: Use $(BISON) to find bison. Roll VERSION
2215 to 3.98. Revise gdb.tar.Z procedure to produce a file
2216 called gdb-$(VERSION).tar.Z but which unpacks into a
2217 directory called "gdb". Move non-source files out of
2218 $(SFILES_SUBDIR). Pretty up alldeps.mak with comments.
2219 (depend): Don't try to do "gcc expread.y".
2220 (expread.o): Update dependencies by hand.
2222 Mon Jul 29 15:21:09 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
2225 Fixed a variety of small typos that prevented info from formatting
2226 cleanly; altered too-long heading for GPL Appendix, as discussed
2227 w/RMS; Changed date on cover to July 91.
2229 Fri Jul 26 13:20:02 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
2232 (1) Applied some fixes due to comments from Larry Breed (easier ones
2233 through chapsec 5.2)
2234 (2) Eliminated use of @footnote---had my doubts about it anyways, and
2235 it's broken in latest texinfo
2236 (3) Introduced *some* use of [] for optional arguments, where
2237 explanation is not simpler by listing cmd w arg and cmd w/out arg
2238 separately. Still not using @deffn.
2239 (4) Dropped in GPL-2. NOTE: one of GPL-2 or texinfo is broken; a
2240 couple of headings are too long. Need patches to texinfo or revision
2243 * Partial update to README (which still needs work for this
2244 release!): (1) use of configure corrected for new script,
2245 (2) "make gdb.dvi" and "make gdb.info" mentioned.
2247 Wed Jul 24 06:44:02 1991 John Gilmore (gnu at cygint.cygnus.com)
2249 * symtab.c (lookup_symbol): Don't complain right off about
2250 no debug symbols; use the misc function vector first.
2251 (list_symbols): Use misc function vector to find symbols
2252 that don't have debug info, and print them.
2253 (find_pc_symtab): Temporarily avoid fatal() when psymtab
2254 PC range doesn't match symtab PC range, as it does on the
2255 MIPS because our symtab reading isn't perfect.
2257 * dbxread.c (dbx_symfile_read): Make warning about
2258 "no debug symbols" slightly nicer.
2260 * source.c (select_source_symtab): If "main" symbol exists,
2261 but decode_line_spec can't find line info, don't just return
2262 a zero; try other source symtabs or give an error.
2264 * mipsread.c (parse_partial_symbols): Sort the psymtabs by
2265 their low addresses first, then rip through fixing high addrs.
2267 * ns32k-opcode.h (sfsr): Bugfix from Rune Nerg}rd,
2268 <runene@ifi.uio.no>.
2269 (NS32K_SVC_IMMED_OPERANDS): Reverse the #ifndef.
2271 Tue Jul 23 18:52:43 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
2273 * Minor, mostly mechanical, cleanup of doc subdir for clean
2274 makeinfo'ing and TeXing; also ensured gdb-all.texinfo (post-m4)
2275 and gdb.info (post- texinfo2 makeinfo) generated for distribution.
2277 Sun Jul 21 03:54:52 1991 John Gilmore (gnu at cygint.cygnus.com)
2279 Mostly MIPS and general symbol-reading fixups.
2281 * doc/gdbint.texinfo: Add documentation on symbol-reading
2284 * mipsread.c: Remove kludges around #include "ecoff.h".
2285 Remove redefinitions of a_magic, etc, no longer used.
2286 (parse_symbol, ): Convert "Internal:" printfs to complain()ts.
2287 Fix global overview comments to match symfile.c protocol.
2288 (mipscoff_new_init): Eliminate cur_hdr if we have one.
2289 (mipscoff_symfile_read): Eliminate unused code. Avoid
2290 sorting all the symtabs, when all we have read here is psymtabs.
2291 The symtabs are sorted as they are created anyway. Tell
2292 condense_misc_bunches whether we're mainline.
2293 (psymtab_to_symtab_1): Pass filename when recursing, to make
2294 stack trace more informative.
2295 (parse_partial_symbols): Assume cur_hdr as argument.
2296 (read_mips_symtab): Don't clobber cur_hdr, so it can be freed.
2297 Pass cur_hdr implicitly to parse_partial_symbols. Avoid checking
2298 the TYPE_NAME of char *, since that's done in symfile.c.
2299 (free_numargs, parse_symbol, add_symbol, add_block,
2300 shrink_linetable): Declare these fns void.
2301 (upgrade_type): Convert tree of if's to switch. Clean up
2302 bogus "off == 0" handling with a complaint. Avoid setting
2303 field bitpos and bitsize of array with lower and upper bounds.
2304 Check specified bitsize of elements against their actual type's
2305 bitsize, and complain if different. Complain about unknown
2307 (parse_fdr): Don't assume sizeof(char *) == sizeof (struct *).
2308 (psymtab_to_symtab_1): Print names of subsidiary files that
2309 are being read in. FIXME, we read far too many files. This code
2310 is not the problem, the problem is in parse_fdr where the psymtabs
2312 (cross_ref): Result should indicate that we used one aux entry
2313 normally, or two if we encountered a "next" entry. This used
2314 to leave the caller pointing at the wrong aux entry.
2315 (add_symbol): If overflowed cur_block, reallocate it larger,
2316 chase all pointers to it, and complain(), rather than clobber memory.
2317 (shrink_block): Use xrealloc rather than xmalloc-and-copy.
2318 (new_field): Only allocate one field initially, not two.
2319 Pull ++ out of macro argument. Simplify.
2320 (_initialize_mipsread): Avoid initialization of importd
2321 global_psymbols and static_psymbols.
2323 * symfile.c (psymtab_to_symtab): Depend on XXX_psymtab_to_symtab
2324 to properly set pst->symtab; avoid searching for it.
2325 (symfile_fns): Improve comments, add a FIXME.
2326 * dbxread.c: Update comments to reflect symfile protocol.
2327 (read_ofile_symtab, end_symtab): Return the symtab.
2328 (psymtab_to_symtab_1): Set pst->symtab.
2330 * coffread.c (coff_symfile_read): tell condense_misc_bunches
2331 whether we're mainline.
2333 * symfile.h (sym_fns): Remove unused sym_discard member.
2334 * coffread.c, mipsread.c, dbxread.c: Remove XXX_symfile_discard.
2336 * mtrace.c (mtrace): Take effect if mallwatch is set, even if
2337 the environment variable is not.
2338 * infcmd.c (finish_command): Use filtered printfs.
2339 * cplus-dem.c: Add struct tags to a few unnamed structs.
2340 * valops.c (value_coerce_array): Improve comments.
2341 * valprint.c (type_print_varspec_suffix): Print array size only
2342 if greater than zero.
2343 * m88k-tdep.c: Shift some lines left by one space, that had
2344 apparently been trashed at some point.
2345 * TODO: More things to do, a few got done.
2347 Thu Jul 18 22:46:05 1991 John Gilmore (gnu at cygint.cygnus.com)
2349 * symtab.h (LOC_EXTERNAL): Eliminate in favor of LOC_STATIC.
2350 (ldsymoff, ldsymlen, globals_offset, statics_offset): Improve
2352 * dbxread.c (read_dbx_symtab): LOC_EXTERNAL -> LOC_STATIC.
2353 * expread.y, findvar.c, symmisc.c: Ditto.
2354 * printcmd.c (address_info): Update printed forms of LOC_
2355 symbols. Elim LOC_EXTERNAL.
2356 (print_frame_args): Keep track of param stack offsets before
2357 re-looking up to find the local register param is kept in.
2359 * mipsread.c: Use <symconst.h> and <sym.h> rather than <syms.h>.
2360 Further integration of mipsread into gdb. Eliminate unused
2361 routines, duplicate declarations. Handle static symbols in
2362 psymtabs as well as external symbols. When reading symtabs,
2363 insert symbols into the correct block (global, static, or a local
2365 (read_mips_symtab, parse_partial_symbols): Don't pass useless
2367 (mipscoff_symfile_read): Don't call select_source_symtab.
2368 (parse_symbol): Use SYMBOL_VALUE_ADDRESS where appropriate,
2369 rather than SYMBOL_VALUE.
2370 (parse_external): Comment clobbering of top_stack.
2371 (parse_partial_symbols): Update comments. Allocate and parse
2372 static symbols as well as external symbols. FIXME, enum values
2373 are not handled in this pass, but should be. Inline new_psymbol.
2374 Use SYMBOL_VALUE_ADDRESS.
2375 (psymtab_to_symtab_1): Read symbols into global static block
2376 by default (until enter some function's local block context).
2377 (sort_blocks): Clean up STATIC_BLOCK as well as GLOBAL_BLOCK.
2378 (destroy_all_symtabs, new_psymbol): Eliminate, unused.
2380 * source.c (select_source_symtab): Select a source symtab
2381 from either the symtabs or, failing that, the psymtabs.
2382 (list_command): Update error message.
2383 (forward_search_command, reverse_search_command): Use getc, not
2384 fgetc, for speed. FIXME, add comment about buffers that die if
2385 overrun by long line.
2387 * values.c (unpack_field_as_long, modify_field): Avoid shifting
2388 by an entire word, which is not portable, if we have a 32-bit
2389 field. (Code in dbxread.c already turns such bitfields, if
2390 aligned, into ordinary ints, but fixing this will help for other
2391 symbol formats and for future changes.)
2392 * core.c (core_open): Handle ANSI const brain death.
2393 * utils.c (vprintf): Fix varargs typo.
2395 Sun Jul 14 00:42:53 1991 John Gilmore (gnu at cygint.cygnus.com)
2397 * findvar.c (find_var_value): Handle &function better.
2398 * TODO: Document work needed on &fn and &array.
2399 * printcmd.c (print_address_symbolic): New arg is the prefix
2400 to print if a name is printed.
2401 (print_address_demangle): Honor "set print address" now.
2402 Use new arg above to improve spacing of output.
2403 * valprint.c (val_print): When printing function pointers,
2404 print symbolic form too.
2405 * breakpoint.c (breakpoint_1): Use new print_address_symbolic.
2407 Mon Jul 8 19:02:46 1991 John Gilmore (gnu at cygint.cygnus.com)
2409 * core.c (memory_error): Reword error msg to mislead less.
2411 * mips-pinsn.c (print_insn_arg 'd'): Print $ with reg name.
2413 * mipsread.c (read_mips_symtab, read_the_mips_symtab,
2414 parse_partial_symbols): Use newer BFD internals (external_filehdr
2415 and external_aouthdr), byte-swap the fields that we care about
2416 before using them, and make the file header data local to
2417 read_the_mips_symtab rather than global.
2419 Sat Jul 6 01:34:15 1991 John Gilmore (gnu at cygint.cygnus.com)
2421 * ns32k-opcode.h (movmw, movmd): Fix opcodes. Bug fix
2422 from Rune Nerg}rd <runene@ifi.uio.no> on 5 Jul 1991.
2424 * main.c (command_line_input): Flush stdout and stderr
2425 before every call to readline. This reportedly fixes a bug
2426 that comes up in Sys V running emacs-gdb and/or xxgdb,
2427 when stdin/out are pipes or sockets.
2429 Thu Jul 4 14:47:06 1991 John Gilmore (gnu at cygint.cygnus.com)
2431 * configure.in, Makefile.in: Avoid rebuilding "depend" as much.
2432 Avoid declaring Makefile dependencies, because GNU Make stupidly
2433 tries to update it if we do.
2435 * coffread.c: Revise for minor changes to bfd internal coff
2438 * configure: If -template= is given a relative path, make it
2439 absolute before recurring in subdirectories.
2441 * configure, configure.in, Makefile.in: Install "configure" script
2442 as replacement for config.gdb.
2443 * config.gdb, Makefile.dist, Makefile.sdir: Remove
2444 * README: Update for configure, mostly. FIXME.
2446 * Add dec3100 as equivalent to littlemips. Indicate in all host &
2447 target config files that they are for the host. When the lines
2448 get copied into the Makefile, this makes it more obvious what's
2451 Mon Jun 24 23:49:07 1991 John Gilmore (gnu at cygint.cygnus.com)
2453 * sparc-opcode.h (trap opcodes): Avoid leading spaces or
2454 tabs, which end up in the disassembler output inadvertently.
2456 Wed May 29 23:01:03 1991 John Gilmore (gnu at cygint.cygnus.com)
2458 Make it compile cleanly in an ANSI GCC2 environment.
2460 * blockframe.c: <stdio.h>
2461 * cplus-dem.c: free takes a void *, ifdef __STDC__
2462 * dbxread.c (read_huge_number): avoid gcc2 bug hoisting calc of
2464 * defs.h (alloca): Avoid doing anything if alloca already def'd.
2465 * stddef.h, stdlib.h: Remove these files.
2466 * symtab.c: Avoid declaring qsort, close.
2467 * symfile.c: Avoid declaring close.
2468 * utils.c (vprintf): Declare "ap" arg as proper va_alist.
2469 * sparc-tdep.c: Avoid including lots of Sun-host-specific files.
2471 Assorted other changes.
2472 * dbxread.c: include "libaout.h", not "liba.out.h".
2473 * printcmd.c (print_frame_args): Set recurse properly for
2474 indentation of struct and array parameters.
2475 * valops.c (value_cast): Allow cast to void.
2476 * infrun.c (resume): If NO_SINGLE_STEP, call machine dependent
2477 single_step() in a target-independent fashion.
2478 * sparc-tdep.c (single_step): Don't call ptrace ourselves, just
2479 set up to be ready to continue. This makes us target independent.
2480 * infptrace.c (child_resume): Remove call to single_step; now
2481 can single step a SPARC target of any kind.
2483 Wed May 22 18:18:24 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
2485 * Makefile.dist, doc/gdb.texinfo, doc/*-m4.texinfo: split up GDB
2486 docn into separate sections---basically chapters, plus two loose
2487 pieces that can be configured to go in different places. This
2488 allows GNU m4 to preprocess the manual without coredumping.
2490 * Makefile.dist: tell TeX where to find texinfo.
2492 Mon May 20 12:15:04 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
2494 * Makefile.dist, doc/gdb.texinfo: respectively create, and use,
2495 the new target "rdl-apps.texinfo" which captures the Makefile
2496 variable that records where to find the Readline libraries.
2498 Sun May 19 05:36:59 1991 John Gilmore (gnu at cygint.cygnus.com)
2500 * tahoe-pinsn.c: #include "tahoe-opcode.h", not "opcode.h".
2501 * tm-tahoe.h (FIX_CALL_DUMMY): Ignore more parameters.
2502 * defs.h (const, volatile): Only define if not already defined.
2503 * Makefile.dist (gdb.tar.Z): Create doc subdir w/out CVS/RCS crud.
2505 * README: Update for release 3.95.
2506 * config.gdb: Don't create readline dir in subdir builds.
2507 * main.c: Include with "..." form for non-system include files,
2508 so "gcc -MM" for "make depend" works.
2509 Include readline files with "...h" rather than <readline/...h>.
2510 * mipsread.c: Include "ecoff.h" rather than "intel-coff.h".
2512 * coffread.c: Undo minor damage done by Rich Pixley. Use
2513 different internal and external representations of COFF
2514 data structures. Use new BFD routines for swapping them in and
2516 * symfile.c (free_named_symtabs): Avoid freeing file names that
2517 are null or empty. Old i960 tools seem to produce files that
2518 claim to have empty names, causing each successive file read
2519 to blow away the previous one.
2520 * sparc-xdep.c (deferred_stores): Repair minor damage by Rich.
2521 Move deferred_stores to top of file, but don't separate its
2522 #define's from its variable. Add commentary.
2523 * Makefile.dist: Fix Rich damage; undo "configure" changes in
2524 favor of keeping the (working) config.gdb. Move readline
2527 Fri May 17 12:49:56 1991 Per Bothner (via gnu at cygint.cygnus.com)
2529 * dbxread.c (read_struct_type): Try to handle g++ version 1 MI
2531 * infptrace.c (fetch_registers): no result, since now void.
2532 * tconfig/news: target depends on m68k-tdep too.
2534 Fri May 17 14:40:14 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
2536 * Makefile.dist: added readline/inc-*.texinfo to dependencies for
2539 * readline/inc-history.texinfo, readline/inc-readline.texinfo:
2540 applied various small fixes due to or inspired by RMS comments
2542 * doc/gdb.texinfo: finished using all RMS comments, save those for
2543 appendices on readline and cmd history (which are in other source
2546 Thu May 16 18:06:05 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
2548 * doc/gdb.texinfo: (1) Updated w/ref to RMS comments through
2549 chapter 9; (2) documented 'break' command's menu mode for
2550 overloaded names, in response to hgs problem report C++ p-31
2552 Wed May 15 11:02:48 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
2554 * doc/gdb.texinfo: (1) better introductory example; (2) more
2555 consistent use of @code, @samp, @file, @kbd throughout; small
2556 cleanups to first three nodes; (3) new "Contributors" node;
2557 (4) Appendix, Renamed Commands; (5) divert specialized startup
2558 instructions to "Targets" chapter for generic manuals, while
2559 leaving them up front for manuals specific to specialized
2560 environments; (6) apply fixes from RMS comments through chapter 4.
2562 * pretex.m4: modify explanatory text slightly (and redefine
2563 "regexp") to keep GNU m4 from complaining. (It still crashes
2564 later, but one step at a time...)
2566 Wed May 15 10:32:12 1991 John Gilmore (gnu at cygint.cygnus.com)
2568 * readline/readline.c (update_line): Avoid dereferencing a pointer
2569 before comparing it to its bounds. Saber caught this.
2570 (init_terminal_io): Don't set BC from the "pc=" termcap variable,
2571 and only set PC if tgetstr returned non-null. Saber caught this.
2573 Tue May 14 16:29:53 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)
2575 * Makefile.dist: put gdb.dvi stuff (updated to use M4 preprocessor
2576 stuff for config manual) here where it counts; updated
2577 to use new subdir structure (gdb/doc/).
2579 * Makefile: generated from above via
2583 * gdbint.texinfo: added instructions on generating gdb.info* files
2584 locally for release. These are ordinary info
2585 files, formatted from gdb.texinfo (via gdb-all.texinfo, see
2586 Makefile)---but due to use of texinfo 2, can't count on makeinfo
2587 to generate these, so we distribute them already formatted.
2589 * gdb.texinfo: included full Info node and menu crud (as generated
2590 by C-u M-x texinfo-master-menu using the texinfo-2 elisp code).
2592 * Makefile: updated "gdb.dvi" target to use M4 preprocessor;
2593 put in comments-for-future gdb.info target (one day makeinfo will
2596 Tue May 14 13:51:36 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)
2598 * gdb.texinfo: Updated to include new or old undocumented
2599 commands, at least the following (perhaps some others I forgot to
2600 record): info f, info float, info path, info program, info s, info
2601 set, info source, info terminal, info types, info user, set/show
2603 Also covered all recent GDB command renames for v4.
2605 Mon May 13 14:57:46 1991 John Gilmore (gnu at cygint.cygnus.com)
2607 * mipsread.c: Rather than keeping count of how many symtabs
2608 and psymtabs we have, for sorting purposes, count them when
2609 we need to sort. This fixes bug in rereading of symbol tables.
2611 Fri May 10 15:43:33 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)
2613 * infcmd.c: renamed "info path" to "show paths"

2628 symtab.h, target.c, target.h: Lint.
2629 * core.c: setup and select frame after reading shared libs,
2630 else reading shared libs will clobber them. Lint.
2631 * utils.c (error): Force out any buffered wrap text.
2633 Fri May 3 22:01:56 1991 John Gilmore (gnu at cygint.cygnus.com)
2635 * remote.c: Remove decls of memory_insert_breakpoint
2636 and memory_remove_breakpoint, no longer used. (Suggestion of
2639 * Makefile.dist: use ${subdir} in paths of BFD and LIBIBERTY,
2640 to make it easier to interface to "configure"'d libraries.
2642 Fri May 3 13:10:01 PDT 1991 Roland Pesch (pesch at fowanton.cygnus.com)
2644 * valprint.c: introduce "set p", "set pr", "show p" and "show pr" as
2645 aliases for set/show print.

2775 Remove from_tty arg to mod_path.
2776 Put symfile_bfd in {coff,dbx}read.c not symfile.h.

3196 * dbxread.c (read_dbx_symtab): Allow N_SOL to cleanly take us back
3197 to the main file, as well as to include files. Also, put global
3198 functions into the global psymtab, to make "i fun" work.
3199 (end_psymtab): Free named symtabs and psymtabs for a file, once a
3200 new psymtab for it has been read.
3201 * coffread.c (end_psymtab): Free named symtabs and psymtabs for
3202 a file, once a new symtab has been read for it.
3203 * mipsread.c: FIXME. We need to do the same for MIPS, but it
3204 looks harder to determine the top-level block before it's been
3205 queued to the psymtab list.
3207 * symfile.c (symbol_file_add): Use filtered printing and wrap it.
3208 If we have wiped out any old symbol tables, clean up at end of

3224 static psymbols list.
3225 (types_info): Restore this function from its untimely #if 0.

3247 is the first symbol read, even if not mainline.
3248 (dbx_psymtab_to_symtab): symfile might be zero, cope.
3249 * exec.c (exec_ops): Add_syms_addr is valid in our tvec.
3250 (set_section_command): New command ("section xxx yyy" -- should
3251 be renamed to "set section xxx yyy" FIXME) which sets the
3252 base address of a section of the exec file, overriding the
3253 virtual address that BFD reports.
3255 Fri Apr 5 17:14:39 1991 John Gilmore (gnu at cygint.cygnus.com)
3257 * exec.c: Add add_syms_addr_command to exec_ops, so you can

3262 * tm-i386v.h (FLOAT_INFO): Don't define it, since the code
3263 for printing the float info is host-dependent, not
3264 target-dependent. FIXME.
3265 * i386-pinsn.c: Move #includes to top, remove useless ones.
3266 * i386-tdep.c: Don't bother including <.../reg.h> since we
3267 don't use it (and it doesn't exist on host systems).
3269 * ieee-float.c (ieee_extended_to_double): Convert NaN to Inf.
3270 Convert negative numbers properly.
3271 (ieee_test): Make numbers really random; fix format arg.
3273 * infcmd.c (attach_command, detach_command): Don't repeat on CR.
3274 * core.c (core_detach): Unpush core_ops, which might not be on
3275 top. We used to just pop the top, which broke things. Don't
3276 need dont_repeat() any more.
3277 (core_file_command): Psst! Don't repeat it.
3278 * remote-nindy.c (nindy_detach): Don't need dont_repeat() now.
3279 * expprint.c (print_subexp): Avoid switch fallthru on
3280 BINOP_ASSIGN_MODIFY, so we can print += and such.
3281 * frame.h: Fix typo.
3282 * inflow.c (kill_command): After killing inferior, print our
3283 current frame in the core file, if we have one.
3284 (generic_mourn_inferior): When inferior dies, either select
3285 the current frame (in the new target, e.g. core file), or
3286 set both the current and selected frames to NULL.
3288 Changes from Peter Schauer.
3290 * infptrace.c: Avoid <sys/ptrace.h> on USG.
3292 * Make all file names fit in 14 characters (sigh and damn!):
3293 mv hp300hpux-xdep.c hp300ux-xdep.c
3294 mv symmetry-xdep.c symm-xdep.c
3295 mv symmetry-tdep.c symm-tdep.c

3301 mv remote-sa.m68k.shar rem-m68k.shar
3302 mv remote-multi.shar rem-multi.shar
3303 * Makefile.dist, README, config.gdb, convex-pinsn.c,
3304 tconfig/symmetry, tconfig/vxworks960, tconfig/vxworks68,
3305 xconfig/hp300hpux, xconfig/symmetry: Change names to shorter
3308 * command.c (user_info_1, user_info): New command for listing
3309 the user-defined commands.
3311 Wed Apr 3 15:00:26 1991 John Gilmore (gnu at cygint.cygnus.com)
3313 * dbxread.c (really_free_pendings): Clear file_symbols
3314 and global_symbols after freeing them; otherwise, running
3315 this function twice (if it appears twice on the cleanup
3316 chain), we try to free things twice.
3318 * dbxread.c (read_dbx_symtab): Calculate end_of_text_addr
3319 based on text_addr (the address of text in core), not on addr (the
3320 offset between text in the .o file and in core). This change
3321 is from Peter Schauer.
3323 * main.c: Define ALL_CLEANUPS as a cast of zero.
3324 (return_to_top_level): Use it.
3325 (main): Do all cleanups after each command run as part
3326 of the gdb startup sequence. Also do all cleanups before
3327 entering the command loop, and every time we exit the command
3328 loop and reenter. Before, the cleanups from the startup sequence
3329 were being left undone until the first error!
3330 (command_loop): Rename do_nothing cleanup to command_loop_marker
3331 so we can see it easily when examining the cleanup chain.
3332 (init_signals): Add another do_nothing for signal handling.
3333 (quit_command): Only try to kill target if it has execution.
3334 Problems in the target stack got us into a state where
3335 inferior_pid was nonzero but none of the targets had execution.
3336 In this state you couldn't exit gdb.
3338 * dbxread.c: Two changes from Peter Schauer.
3339 (echo_command): Fflush output after an echo command.
3340 (show_history): Pass all args to cmd_show_list.
3342 * utils.c (init_malloc): Call mtrace to turn on tracing
3343 if the environment variable MALLOC_TRACE is set to a file name.
3344 * mtrace.c: Add source file which provides a log of every malloc,
3345 free, and realloc to a trace file.
3346 * mtrace.awk: Add source file which analyzes the trace file.
3347 * Makefile.dist (GNU_MALLOC, MALLOCSRC): Add mtrace.{c,o,awk}.
3348 (VERSION): Roll to 3.94.3.
3350 * breakpoint.c (breakpoint_1): Add a space to "i watch" output.
3351 (check_duplicates): Don't bother with watchpoints.
3352 (set_raw_breakpoint): Comment about danger of this routine.
3353 (watch_command): Parse and eval all args before calling
3356 * solib.c (find_solib): Avoid error in referencing memory to
3357 see if any more shared libraries have been added. This is
3358 particularly useful if the target has terminated. Bug reported
3361 Changes from Peter Schauer <pesrem@regent.e-technik.tu-muenchen.de>
3362 in bringing up 3.94.2 on the Sun-3.
3364 * Makefile.dist: Include CFLAGS in rule for cplus-dem.o.
3365 * breakpoint.c (enable_breakpoint): Check for valid watchpoint
3366 expression (in scope) before reenabling watchpoint.
3367 * signame.c (init_sigs): Add missing declaration of i, fix
3368 sys_siglist declaration.
3369 * source.c (list_command): Fixed range computation to use
3371 * stack.c (backtrace_command): Do not allow command if target has
3372 no stack, print informative error message.
3373 * target.c (target_command): Do not write into command line
3374 because this fails if the target command is used in a user defined
3375 command. [This change was enhanced by gnu to support any-
3376 unique-prefix matching on target names.]
3377 * valops.c (value_struct_elt): Avoid infinite loop on an
3378 erroneous attempt to print the member of function (try p main.p).
3380 Mon Apr 1 17:05:45 1991 John Gilmore (gnu at cygint.cygnus.com)
3382 * expread.y (name_no_typename): Avoid reduce/reduce errors
3383 caused by ambiguity in handling NAME_OR_INT and NAME_OR_UINT.
3384 Since the GDB parser really doesn't use name_no_typename in a
3385 name-only context, the parser can't tell the diff between
3386 names and numbers here. Avoid allowing a name_no_typename
3387 to be a NAME_OR_*INT to resolve the conflict.
3389 Sun Mar 31 20:12:07 1991 John Gilmore (gnu at cygint.cygnus.com)
3391 Bugfixes from Mark Fox (markf@wrs.com) (test=testField.c):
3393 * valprint.c (val_print_fields): bitfield printing didn't handle
3394 byte order. Indirect through a few more fns to cope.
3396 * values.c (modify_field): also cope with byte order.
3398 Sat Mar 23 10:02:21 1991 John Gilmore (gnu at cygint.cygnus.com)
3400 Cleanup for release 3.94.2:
3402 * Makefile.dist: Pull REMOTE_OBS. Fix saber includes for BFD
3403 include files. Roll version to 3.94.2.
3405 * coffread.c (init_stringtab): Read length into unsigned char
3406 array before swapping; don't assume 32-bit longs.
3408 * target.c (target_info): Don't bother with get_sym_file, just use
3409 the symfile global variable.
3410 * symtab.h, symfile.c (get_sym_file): Delete it.
3412 * dbxread.c (dbx_symfile_init): Don't depend on long == 4 bytes.
3413 (define_symbol): Set symbol line number to 0 if not gcc-compiled.
3414 (read_type): Replace one more error() with complain().
3416 * mipsread.c (parse_partial_symbols): Replace printf with complain.
3418 * i960-tdep.c: Fix copyright attribution.
3420 * config.gdb: Quote all backquotes in doublequotes. You can
3421 quote me on that. BSD 4.4 shell found this one.
3423 * infptrace.c (throughout): The third argument to ptrace is an
3426 * infrun.c (wait_for_inferior): When program has terminated, we
3427 have to call target_terminal_ours before we pop that target off
3428 the stack (e.g. before a call to target_kill or
3429 target_mourn_inferior). This fixes problem where a program
3430 terminates, then GDB stops for (tty output) and you have to type
3431 "fg" to the shell to resume it. FIXME: This code for what to
3432 do after termination really should be in normal_stop instead.
3434 * gdbcore.h (read_memory_check): Change declaration; it changed
3437 * terminal.h: Include <sgtty.h> before <sys/ioctl.h>, since in BSD
3438 4.4 prereleases, this avoids a bug in their sgtty compatability
3440 * remote.c: Use terminal.h rather than hand-rolling the same.
3442 * signame.c, signame.h (psignal): Arg is unsigned, not int.
3443 * utils.c (strsave, strstr): Fix arg types.
3444 * valprint.c (val_print): lint
3446 MIPS symbol table support from Per Bothner:
3448 * symfile.c (symtab_fns): Remove initializer table that needs to
3449 be hacked for each new symbol file format supported.
3450 (add_symtab_fns): New function, chains symbol table
3451 handlers into the global list.
3452 (symfile_init): Search this list.
3453 * symfile.h: Add next pointer, declare add_symtab_fns.
3454 * coffread.c (_initialize_coffread): Call add_symtab_fns.
3455 * dbxread.c (_initialize_dbxread): Call add_symtab_fns.
3457 * mipsread.c (psymtab_to_symtab_1): return void instead of (struct
3458 symbol *). Thus, we no longer need the hack to trash
3459 pst->filename. Good, since that hack confused code in symfile.c!
3461 (reorder_symtabs, destroy_all_symtabs): Removed static
3462 all_symtabs, which was used to qsort symtabs in reorder_symtabs.
3463 Instead, the latter now uses a temporary array (stack-allocated
3464 from an obstack, and then freed).
3466 (parse_symbol): Added a hack to fix up BLOCK_{START,END} if they
3467 haven't been set in the outermost stBlock of a procedure. This was
3468 a problem with f77 binaries on Ultrix 4.?.
3470 (new_symtab, new_symbol, new_type): Continue changing code to use
3471 obstacks more and otherwise conform to dbxread internal style.
3472 Made the free_code of symtabs be free_linetable (as in dbxread)
3473 instead of free_contents. This implies memory leaks when reading
3474 a new symbol table, until the conversion is finished. Did change
3475 (struct symbol) and (struct type) to be allocated on the
3476 symbol_obstack. Blocks and blockvectors are among the things
3479 * mipsread.c (parse_partial_symbols, parse_fdr): It hasn't been
3480 tested much, but it solved one problem (reported by Meissner), and
3481 cleans up some other things. The problem happened when an
3482 included file contains actual code (functions) and not just
3483 definitions. The mips coff is a little inconvenient there, since
3484 it may cause a procedure to be mapped to the wrong psymtab.
3486 * mips-tdep.c (heuristic_proc_desc): Minor cleanup.
3487 * mips-xdep.c (fetch_core_registers): Minor cleanup. FIXME,
3488 this will need work for the new core paradigm.
3490 Opcode patches from the net:
3492 * mips-opcode.h: fix incorrect disassembly of the mfc1, cfc1, and
3493 ctc1 instructions. Also, the cvt.d.w and cvt.s.w instructions were
3494 missing altogether - they are added here. From Bruce Bauman.
3495 * mips-opcode.h: The low mask for C0 instructions was too small.
3496 From Garrett Lau. I modified the fix to check the entire 32-bit
3499 * ns32k-opcode.h: Fix opcodes for deiw and deid. From Bruce
3502 Thu Mar 21 12:56:46 1991 John Gilmore (gnu at cygint.cygnus.com)
3504 Roll in changes from Per Bothner (Tue, 25 Sep 90 11:11:04):
3506 * dbxread.c (read_type): Pointer subtraction (value_sub in
3507 valarith.c) sometimes failed because the types of the
3508 pointers being subtracted were not identical.
3509 These differed because dbxread.c was allocating pointer types
3510 using dbx_alloc_type+smash_to_pointer_type instead of
3511 lookup_pointer_type. I failed to find a justification for the
3512 former, so I changed it to use the latter. Similarly, I
3513 replaced smash_to_function_type by lookup_function_type,
3514 and smash_to_reference_type by lookup_reference_type.
3516 * mipsread.c (parse_symbol, upgrade_type, parse_procedure,
3517 _initialize_mipsread): corresponding changes.
3519 * symtab.c (smash_to_{pointer,reference,function}_type): eliminate.
3521 * source.c (mod_path): Do tilde_expand on each component of the path,
3522 rather than on the (list of) paths as a whole.
3523 (print_source_lines): Set first_line_listed in addition to
3524 current_source_symtab and current_source_line. If the source was
3525 not findable, after a "dir" command to fix the problem,
3526 a "list" would get the wrong lines.
3528 While I was there... (gnu):
3530 * dbxread.c (read_type): Change error to complaint.
3532 Thu Mar 21 12:56:46 1991 John Gilmore (gnu at cygint.cygnus.com)
3534 First attempt at detailed understanding of symbol table memory alloc.
3536 * dbxread.c (dbx_symfile_read): Free our string table if we
3537 aren't the mainline. Free the "info" struct since we're done with
3539 (init_psymbol_list): Free any previously allocated psymbol lists.
3540 (): FIXME: Should realloc-down the psymbol lists when done reading
3541 the main symbol file?
3543 * symmisc.c (free_symtab): Free fullname field too.
3545 * xm-hp300hpux.h (USG): #undef then #define so Makefile can -D.
3546 (REGISTER_ADDR): Make result type unsigned int.
3548 * xconfig/{i386*,hp300hpux,altosgas,altos}: All config files that
3549 define REGEX must also define REGEX1 (its dependency).
3551 Tue Mar 19 21:28:57 1991 John Gilmore (gnu at cygint.cygnus.com)
3553 * tconfig/i960: No longer works, points you at vxworks960 or
3556 * xgdb.c, XGDB-README: Remove file. Users can get the much
3558 * Makefile.dist: Remove all trace of xgdb.
3560 * breakpoint.c (breakpoint_1): Pass demangle arg to
3561 print_address_symbolic.
3562 (clear_breakpoints): Remove unused function.
3563 (breakpoint_re_set_one): Guts of breakpoint_re_set.
3564 (breakpoint_re_set): Use catch_errors to do them all anyway.
3566 * gdb-int.texinfo (Host versus Target): Add section on what is
3567 a "host" feature versus what is a "target" feature.
3569 * infcmd.c (path_command, path_info): Handle the PATH variable
3570 (object search path) as conveniently as the source search path.
3571 * environ.c (set_in_environ): Set some vars in GDB's environment,
3572 in addition to the child's. PATH, G960BASE, G960BIN for starters.
3573 * source.c (mod_path): New function, from guts of
3574 directory_command, modifies a path. Used by path_command.
3575 (directory_command): Call it.
3576 * defs.h (strsave): Declare.
3578 * utils.c (sevenbit_strings): Add new printing option.
3579 (printchar): Use it.
3580 (strsave): Provide this handy helper routine.
3581 (set_width_command): Rename set_screen_width_command.
3582 (_initialize_utils): "set screen-width" => "set width";
3583 "set screen-height" => "set height"; add sevenbit-strings.
3585 * infcmd.c (do_registers_info): Print floating point registers
3586 in raw hex as well as float format, regardless of whether it is
3587 a "virtual" convertible register.
3588 * tm-sparc.h (PRINT_REGISTER_HOOK): Print every pair of float
3589 regs as a double, just in case it's being used that way.
3590 * values.c (unpack_long): Comment on array/function coercion.
3591 (unpack_double): Argument is in target byte order now. For
3592 integer arguments, just call unpack_long and float the result.
3593 * m68k-tdep.c: include defs.h for "const" handling.
3594 * remote-nindy.c: Use ieee-float stuff.
3595 (nindy_fetch_registers): Unpack double regs to host double, then
3597 (nindy_store_registers): Pack extendeds to host double, flip
3598 around by misusing unpack_double, send as target double.
3600 * tm-vxworks68.h (FRAME_CHAIN): Handle current frame pointer of
3601 zero, as when stopped at the first instruction of a process.
3603 * blockframe.c: Fix filename in comment (param.h => tm.h).
3604 * sparc-tdep.c (skip_prologue): More explicit nudging comments.
3605 * tm-68k.h: Fix typos.
3607 Fri Mar 15 01:09:34 1991 John Gilmore (gnu at cygint.cygnus.com)
3609 Changes from a bringup on the DEC Vax under Ultrix 4.0.
3611 * coredep.c (fetch_core_registers): Pass end-address of register
3612 section to register_addr as expected. Don't call supply_register
3613 if we'd just pass it garbage.
3615 * dbxread.c (read_dbx_symtab): Skip N_NSYMS on Ultrix.
3617 * exec.c (xfer_memory): Use boolean xfer_fn result, not int.
3619 * target.c (push_target, target_info): Cast enums to int for < or
3622 * stack.c (print_frame_info): Identify source file & line
3623 even if we can't print it.
3625 * xm-vax.h (MISSING_VPRINTF): No longer missing in Ultrix V4.0.
3627 Sat Mar 9 10:08:20 1991 John Gilmore (gnu at cygint.cygnus.com)
3629 Clean up IEEE floating point support.
3631 * ieee-float.h: New file.
3632 * ieee-float.c: Write real routines to convert between host
3633 doubles and various target IEEE extendeds.
3634 * m68k-xdep.c: Eliminate assembler code for extended floats.
3635 * xconfig/{3b1,altos,altosgas,hp300bsd,isi,news,news1000,sun2os3,
3636 sun2os4,sun3,sun3os3,sun3os4}: Eliminate use of m68k-xdep.o.
3637 * tm-i960.h, tm-68k.h (REGISTER_CONVERT_TO_VIRTUAL,
3638 REGISTER_CONVERT_TO_RAW): Use ieee_extended_to_double and
3639 double_to_ieee_extended.
3640 * i960-tdep.c: Define ext_format_i960.
3641 * m68k-tdep.c: Define ext_format_68881.
3642 * sparc-tdep.c: Define ext_format_sparc, though unused.
3643 * Makefile.dist (HFILES): Add ieee-float.h.
3644 * inftarg.c: #include "ieee-float.h" for the REGISTER_CONVERT
3647 Obsolete the "coffstrip" program in favor of using BFD's strip.
3649 * nindy-share/coffstrip.c: Remove file.
3650 * nindy-share/nindy.c (coffstrip): Routine to run bfd_strip.
3651 * Makefile.dist: Remove references to nindy-share/coffstrip.c.
3652 * tconfig/nindy960: Remove reference to coffstrip.o.
3654 * Makefile.dist: Roll version number to 3.94.1 (not yet final).
3656 Wed Mar 6 09:56:45 1991 John Gilmore (gnu at cygint.cygnus.com)
3658 * symfile.h: Add symfile_bfd, common between dbxread and coffread.
3659 * dbxread.c: Remove static symfile_bfd.
3660 * infcmd.c (do_registers_info): Add PRINT_REGISTER_HOOK, though
3662 * inftarg.c (child_detach): Pop the child_ops vector if the
3663 detach is successful.
3664 * remote-nindy.c (nindy_create_inferior): Don't push a new
3665 nindy_ops since nindy uses the same one for execution and memory
3667 * core.c (core_ops): Use child_attach and child_create_inferior
3668 rather than default attach and create_inferior functions.
3670 Handle floating point registers in core files.
3672 * sparc-xdep.c (fetch_core_registers): Rewrite for float support.
3673 * sun3-xdep.c (fetch_core_registers): Rewrite for float support.
3674 This version untested since BFD doesn't yet support sun3 core
3676 * hp300hpux-xdep.c: Rewrite fetch_core_registers to new calling
3677 conventions. Fix comments and style. This version has not
3678 been compiled yet, since we have no HP inhouse.
3679 * core.c (get_core_registers): Look for two sections, ".reg"
3680 and ".reg2", and pass both to fetch_core_registers sequentially.
3682 Revise directory path yet again.
3684 * source.c (forget_cached_source_info): Not static any more.
3685 (init_source_path): New default source path is "$cdir:$cwd".
3686 (dir_command): Handle variable arguments ($cdir, $cwd).
3687 (source_info): Print "Compilation directory" rather than
3688 "Originally compiled in" to remind people of $cdir.
3689 (openp): If the path contains $cwd, use current directory.
3690 (open_source_file): If compilation directory is known, replace
3691 first $cdir in path with the compilation directory.
3692 (print_source_lines): Even if we can't print the lines, set the
3693 current symtab and line for future commands like "info source" or
3694 "breakpoint". Also, error message now contains the file name,
3695 line number, and file access error message.
3696 (_initialize_source): Fix help text to describe changes.
3697 * main.c (cd_command): Forget cached source info when we chdir.
3698 * utils.c (strstr): Add simple implementation.
3700 Tue Mar 5 01:41:40 1991 John Gilmore (gnu at fowanton.cygnus.com)
3702 * coffread.c (read_one_sym, init_linetable, init_stringtab):
3703 Byte-swap COFF symbol tables if necessary when reading them in.
3704 Use complain() to replace error message in one spot. Needs
3705 corresponding change in bfd/coff-code.h to make some symbol
3706 swapping routines non-static.
3708 Mon Mar 4 00:53:40 1991 John Gilmore (gnu at cygint.cygnus.com)
3710 Merge changes from Eirik Fuller, for UTek.
3712 * defs.h (errno): Add declaration.
3713 * altos-xdep.c, arm-xdep.c, convex-xdep.c, gould-xdep.c,
3714 hp300hpux-xdep.c, infrun.c, inflow.c, infptrace.c, i386-tdep.c,
3715 i386-xdep.c, pyr-xdep.c, mips-xdep.c, remote-eb.c, remote-nindy.c,
3716 remote-vx.c, source.c, standalone.c, stuff.c, sun386-xdep.c,
3717 symmetry-tdep.c, symmetry-xdep.c, umax-xdep.c, utils.c: Eliminate
3718 declarations of errno.
3720 * remote-eb.c: Define B19200 and B38400 as EXTA and EXTB.
3722 * remote-vx.c: Include <sys/time.h> for UTek; Sun gets it via
3723 <rpc/rpc.h> and <rpc/types.h>.
3725 Sat Mar 2 15:47:55 1991 John Gilmore (gnu at cygint.cygnus.com)
3727 * i960-tdep.c (examine_prologue): Add new argument limit,
3728 which stops the scan at the end of the prologue, or at the PC.
3729 This fixes a problem where it walks down into the code for the
3730 user's statements if that code looks like function prologues.
3731 Mark Fox and I have been bouncing this code back and forth, making
3732 small changes to it. Callers changed to match.
3734 Tue Feb 26 01:47:07 1991 Cygnus John Gilmore (cygnus at yuba)
3736 Cleanup for gdb-3.94 release final:
3738 * Makefile.dist: Remove remote-vx.c, remote-nindy.c, and all
3739 the .c files from vx-share and nindy-share, from the various
3740 macros, since they are not found via ALLDEPFILES.
3741 (SFILES): Add tm-i960.h.
3742 (alldeps.mak rule): Break out ALLDEPFILES_MAINDIR and
3743 ALLDEPFILES_SUBDIR. List all the nindy and vxworks subdir files
3745 (TAGFILES_MAINDIR): Change ALLDEPFILES to ALLDEPFILES_MAINDIR.
3746 (gdb.tar.Z): Use ALLDEPFILES_SUBDIR as well as SFILES_SUBDIR.
3748 Mon Feb 25 16:02:35 1991 Cygnus John Gilmore (cygnus at oldman)
3750 * am29k-tdep.c: Add contribution line.
3751 (examine_prologue): Cache information about function prologues in
3752 the misc-function-vector to avoid lots of references over the
3753 serial line while examining instructions.
3755 * core.c (core_close): New function made from cleanup_core.
3757 * core.c, exec.c, inftarg.c, remote-eb.c, remote-nindy.c,
3758 remote-vx.c, remote.c, target.c, target.h,
3759 Update target_ops vector to add attach, close, and load entries.
3760 Use add_syms_addr_command, not add_file_addr_command, for
3761 add_file. Break out close routine from existing code.
3763 * dbxread.c (really_free_pendings): Don't free pending_blocks;
3764 they are in an obstack.
3765 (read_dbx_symtab): Relocate end_of_text_addr in the psymtab.
3767 (define_symbol): Add symbol type parameter; change callers;
3768 pass type parameter to DBX_PARM_SYMBOL_CLASS macro to allow
3769 it to influence the symbol class on the i960.
3770 (define_symbol): Swap LOC_CONST's into target byte order.
3772 * exec.c (exec_close): New function.
3773 (exec_file_command): Call it.
3775 * findvar.c (read_relative_register_raw_bytes): Doc byte order,
3776 Fix byte order of frame pointer.
3777 (read_var_value): Result of 0 if var's value can't be found,
3778 e.g. missing FRAME_ARGS_ADDRESS. Byte-swap LOC_CONST and
3779 LOC_LABEL values to target order. Add LOC_LOCAL_ARG.
3780 (locate_var_value): Use read_var_value and use its lazy address
3781 as the location of the var's value. Lint.
3783 * i960-pinsn.c (next_insn): Add routine from vxgdb for scanning
3786 * i960-tdep.c (arg_address, i960_frame_find_saved_regs): Remove
3787 obsolete Intel versions in favor of vxgdb versions.
3788 (check_host, byteswap, byteswap_val, reorder_val): Eliminate
3789 code dealing with byte order of values, which Intel did in host byte
3790 order rather than gdb-4's target byte order.
3791 (i960_frame_chain_valid): Move to nindy-tdep.c.
3792 (examine_prologue, skip_prologue, frame_find_saved_regs,
3793 frame_args_address, leafproc_return, saved_pc_after_call,
3794 pop_frame): Add vxgdb versions from Mark Fox.
3795 (examine_prologue, frame_struct_result_address): Add code
3796 to deal with the saved value of G13 (struct return address
3798 (frame_args_address): Modify Mark's version to prefer the
3799 saved value over the current value in the topmost frame.
3800 Cache result in the frame info to avoid performance hair in
3802 (print_fault): Add gdb960 code for printing faults.
3803 (_initialize_i960): Actually call check_host.
3805 * ieee-float.c (ieee_extended_to_double, ieee_double_to_extended):
3806 add stub routines. FIXME, these currently just return zero!
3808 * infcmd.c (program_info): Use PRINT_RANDOM_SIGNAL.
3809 (attach_command): Call target_attach, not target_open, now.
3811 * infrun.c (normal_stop): Make global, not static, for vx_attach.
3812 (child_attach): Rename from child_open.
3813 (wait_for_inferior): Use PRINT_RANDOM_SIGNAL. If stop_pc is zero,
3814 don't confuse it with a zero step_resume_break_address.
3816 * inftarg.c (child_detach): Eliminate inferior_pid test.
3817 (child_files_info): Clean up message a bit.
3818 (child_ops): Use child_attach, not child_open, to attach.
3820 * mem-break.c: #ifdef out the whole file if BREAKPOINT is not
3821 set (e.g. on VxWorks or NINDY). Move read_memory_nobpt from
3822 findvar.c to here, since it depends on the contents of the
3823 shadow_contents of breakpoints, but keep if #if 0 since it is
3826 * nindy-tdep.c: New file, contains nindy_frame_chain_valid, moved
3829 * printcmd.c (address_info): Handle LOC_LOCAL_ARG. Lint.
3830 (ptype_command, display_command): Eliminate have_inferior_p and
3831 have_core_file_p in favor of target_has_stack or
3832 target_has_execution.
3833 (print_frame_args): Handle LOC_LOCAL_ARG. Eliminate duplicate
3834 code for actually finding the values of arguments, though we still
3835 keep track of the maximum stack offset for use in printing unnamed
3836 arguments. Handle missing FRAME_ARGS_ADDRESS.
3838 * remote-nindy.c (i960_print_fault): Move to i960-tdep.c.
3839 (struct nindy_regs): Define registers passed to/from nindy.
3840 (nindy_fetch_registers, nindy_store-registers): Translate between
3841 nindy and GDB formats for the registers.
3842 (dcache_init): Statically allocate the cache, since it was being
3843 allocated by a malloc that was never freed anyway.
3844 (nindy_create_inferior): Error, not core dump, if no exec file.
3845 (nindy_before_main_loop): Use target_load, not target_add_file.
3847 * remote-vx.c (net_load): Specify large timeout for load
3848 requests. Allow user to break out with INTERRUPT.
3849 (net_break): Remove useless code, clean up. Change callers.
3850 (parse-args, skip_white_space, find_white_space): Clean up arg
3851 parsing to cope with quoted strings.
3852 (net_wait, net_quit): Never call error, just return status.
3853 (vx_read_register, vx_write_register): Cleanup status checking.
3854 #ifdef the code based on which CPU we are using (960 or 68k),
3855 FIXME, this should be completely general but it isn't yet.
3856 (vx_xfer_memory, vx_resume): Cleanup status checking.
3857 (vx_run_files_info): Improve message.
3858 (vx_load_command): Renamed from vx_add_file_command. Allow load
3860 (net_ptrace): Remove unused routine.
3861 (vx_wait): Adopt code from vxgdb960 to cope with broken
3862 connections to target machine and prompt to disconnect. Remove
3863 debug printouts. Map some EVENT_'s to SIGnals.
3864 (add_symbol_stub, vx_open): Print names of object files we found,
3865 and "ok" if we read their symbols OK. Clarify output in general.
3866 (vx_attach, vx_detach, vx_kill): Add these commands.
3867 (vx_convert_from_virtual, vx_convert_to_virtual): Simplify.
3868 (vx_run_ops): Turn off all_mem, to avoid spurious msg in the
3869 "info files" output, and create_inferior, since we already have
3872 * stack.c (frame_info): Replace Frame_unknown with 0.
3873 (print_frame_arg_vars): Handle LOC_LOCAL_ARG.
3874 (return_command): Pop until the PC matches as well as the FP,
3875 so it works even if the FP is shared with another function,
3876 as in "frameless" or "leaf" procedures.
3878 * symfile.c (load_command): renamed from add_file_target_command.
3879 (add_syms_addr_command): renamed from add_file_addr_command.
3880 (add_syms_command): Stub to call target_add_syms.
3881 (_initialize_symfile): Change command names and descriptions,
3882 add-file => add-syms, and load from alias to its own command.
3884 * target.c (kill_or_be_killed, maybe_kill_then_attach,
3885 maybe_kill_then_create_inferior): Default for attempts to start
3886 a process, if one is already running, is to ask about killing
3887 it and retry if yes.
3888 (upstack_create_inferior): #if-0 it, strata obsolete it.
3889 (push_target, unpush_target, pop_target): to_close() a target
3890 before unstacking it.
3891 (target_info): Renamed from target_files_info.
3892 (_initialize_targets): Rename "i files" as "i target", accessible
3895 * target.h: Improve comments about the target_ vectored routines.
3897 * tm-i960.h: Remove NINDY-specific stuff to tm-nindy960.h.
3898 Convert commenting style to standard GNU style.
3899 (DBX_PARM_SYMBOL_CLASS): allow LOC_LOCAL_ARG's to be recognized.
3900 (SKIP_PROLOGUE): No longer a no-op.
3901 (SAVED_PC_AFTER_CALL): Now handles leaf procedures.
3902 (*_REGNUM): Sort register numbers.
3903 (REGISTER_BYTES, REGISTER_BYTE, REGISTER_RAW_SIZE,
3904 MAX_REGISTER_RAW_SIZE, REGISTER_CONVERTIBLE,
3905 REGISTER_CONVERT_TO_VIRTUAL, REGISTER_CONVERT_TO_RAW): Float regs
3906 are now 10 byte extendeds, not 8 byte doubles.
3907 (FRAME_CHAIN_VALID): Make this config-dependent, since it differs
3908 for nindy versus vxworks targets. FIXME, this should possibly go
3909 in the target vector.
3910 (EXTRA_FRAME_INFO, INIT_EXTRA_FRAME_INFO): Cache both
3911 frame_saved_regs and arg pointer with each frame.
3912 (FRAMELESS_FUNCTION_INVOCATION): New leafproc support.
3913 (FRAME_ARGS_ADDRESS): Use cached result.
3914 (FRAME_ARGS_ADDRESS_CORRECT): New, avoids g14 guessing.
3915 (FRAME_FIND_SAVED_REGS): Change arg to subsidiary fn.
3916 (PRINT_RAMDON_SIGNAL): Call print_fault.
3917 (POP_FRAME): Now works.
3919 * tm-nindy960.h: Break this off tm-i960.h. NINDY-specific
3920 option parsing and startup; STACK_END_ADDR, FRAME_CHAIN_VALID,
3921 BREAKPOINT, and DECR_PC_AFTER_BREAK are here.
3922 (ADDITIONAL_OPTION_HANDLER): use target_load, not
3925 * tm-vxworks960.h: Break this off tm-i960.h. VxGDB specific
3926 startup; DECR_PC_AFTER_BREAK, and FRAME_CHAIN_VALID are here.
3928 * valarith.c (value_subscripted_rvalue): Avoid handling
3929 floats and doubles specially; it gave alignment errors. Lint.
3931 * valops.c (value_of_variable, value_of_this): Error if unknown
3934 * valprint.c (print_floating): Bcopy rather than pointer-deref,
3935 to avoid alignment problems.
3936 (value_print): Handle unknown value address.
3937 (cplus_val_print): Two args are ignored; remove them. Change caller.
3938 (val_print): Use unpack_long rather than pointer-deref.
3941 (unpack_long, unpack_double): Use bcopy rather than pointer-deref
3942 to avoid alignment problems.
3943 (value_being_returned): Error if return value unknown.
3944 (set_return_value): Add bogosity warning, FIXME. *
3946 * TODO: A woman's work is never done.
3948 * Makefile.dist: Distribute REMOTE_OBS into tconfig files.
3949 Separate INCLUDE_CFLAGS for use with lint. Add LINTFILES.
3950 Add ieee-float.o to OBS.
3951 * tconfig/{nindy960,vxworks68,vxworks960}: Include the desired
3952 REMOTE_OBS remote-interface files in the TDEPFILES and TM_FILE.
3953 * tconfig/i960: FIXME. Half-merge, produce warning if config'd.
3955 Changes to generalize the VxWorks RPC protocol slightly, to handle
3956 i960 as well as 68000.
3958 * vx-share/dbgRpcLib.h (VX_SOURCE_STEP): Add.
3959 * vx-share/reg.h: Produce i960 regs #ifdef I80960
3960 * vx-share/xdr_ptrace.c: Skip FPA registers if 960.
3961 * vx-share/xdr_rdb.h: Add SOURCE_STEP struct and xdr decl.
3962 * vx-share/xdr_rdb.c: Add xdr_SOURCE_STEP routine.
3963 * vx-share/xdr_regs.c: Add xdr_regs, xdr_fp_status, xdr_ext_fp
3964 for i960. Change xdr_vectors to xdr_opaques for 68k registers,
3965 so they will move in target byte order rather than network
3966 byte order (happens to be the same).
3968 Mon Feb 25 03:41:44 1991 John Gilmore (gnu at cygint.cygnus.com)
3970 * tm-convex.h (END_OF_TEXT_DEFAULT): Remove #if 0'd block.
3972 Sun Feb 24 00:55:53 1991 John Gilmore (gnu at cygint.cygnus.com)
3975 Add contribution lines to various files, showing where they
3978 * breakpoint.c (break_insn, check_break_insn_size,
3979 read_memory_nobpt): Remove to mem-break.c.
3981 * xm-*.h, param-no-tm.h, tm-29k.h, valprint.c: Change BYTE_ORDER to
3984 * tm-29k.h (STAB_REG_TO_REGNUM): Warn user if symbol table
3985 entry has bad register number. This change is not
3986 tested in this release, FIXME.
3988 * frame.h: Eliminate Frame_unknown in favor of a simple zero.
3991 * value.h: Force value's contents field to be aligned to hold
3992 at least a double or a long long (if supported). This avoids
3993 doing bcopy's in and out of the contents field.
3995 (step_1): Avoid coredump under obscure circumstances when we
3998 * symtab.h (misc_info): Add field to misc function vector for
3999 any kind of cached information the target code desires. AMD
4000 29000 uses this to avoid repeating examine_function_prologue's.
4002 * coffread.c: Lint. Remove static symfile, read_section_header.
4003 core.c (have_core_file_p): Lint: remove.
4004 expprint.c (print_subexp): Lint.
4005 infptrace.c, valops.c, valprint.c: lint.
4007 Roll in changes from vxgdb-5.0.1:
4009 * symtab.h: Comment byte order of each address class. Add
4010 LOC_LOCAL_ARG for frame-relative args (960).
4011 expread.y: Use LOC_LOCAL_ARG where LOC_ARG is used.
4012 symtab.c, symmisc.c: ditto.
4014 * infrun.c (init_wait_for_inferior): Clear stop_signal.
4016 * remote.c (remote_resume): Error if resume with a signal.
4018 * symfile.c (prim_record_misc_function): Clear misc_info.
4019 (fill_in_vptr_fieldno): Check stub type of arg.
4021 * valops.c (value_cast): Avoid looking up names of types whose
4022 name we don't know, to prevent coredump. Sun CC produces typedef
4023 rtx and the name of *rtx is zero...
4025 Mon Feb 18 21:16:25 1991 John Gilmore (gnu at cygint.cygnus.com)
4027 Roll in changes from final AMD 29000 port (Tiemann).
4029 tconfig/am29k: Add COFF_ENCAPSULATE and TARGET=TARGET_AM29K
4030 for ../include/a.out.encap.h. This might not work now that BFD
4031 is separately compiled. Instead, BFD support for encap will have
4032 to translate machine type 29k into the right COFF_MAGIC.
4034 * infcmd.c: Remove references to inferior_pid that aren't used
4035 in actual ptrace calls; use target_has_execution, etc.
4036 (have_inferior_p): Remove function.
4037 (program_info): Print target info rather than "process number";
4038 avoid gratuitous messages unless from_tty.
4039 (run_stack_dummy, finish_command): Set proceed_to_finish.
4040 infrun.c: Remove inferior_pid refs. Decl & init proceed_to_finish.
4041 main.c: Lint. Lose have_inferior_p().
4042 inferior.h (have_inferior_p): Remove, lint.
4043 (proceed_to_finish): Add flag to ask that all regs be saved
4044 by normal_stop, for the few commands that need it, speeding up
4045 serial I/O. Add comments to stop_registers.
4047 * remote-eb.c: Remove newline from breakpoint message we grep
4048 for. Never time out when running the user program.
4052 Wed Feb 13 15:34:40 1991 John Gilmore (gnu at cygint.cygnus.com)
4054 Roll in changes from vxgdb-5.0.1:
4056 * dbxread.c (read_dbx_symtab): If we encounter a "FORTRAN COMMON"
4057 symbol in its raw form, we are processing an unlinked ".o" file.
4058 See if the target environment has assigned it an address, using
4059 target_lookup_symbol (VxWorks does), and enter it into the symtab
4062 * tm-vxworks.h (FRAME_CHAIN, FRAME_CHAIN_VALID): Override usual
4063 68k versions for a simpler version that assumes zero FP at bottom.
4064 Fixes bug of truncated stack reports.
4066 * target.h (target_lookup_symbol): Define this routine's args
4067 and result, finally.
4069 * target.c (nosymbol): Default routine for target_lookup_symbol.
4070 (target_default): Default lookup_symbol and call_function too.
4071 (files_info): Only print has_all_memory warning if a non-dummy
4074 * remote-vx.c (vx_read_register, vx_convert_to_virtual,
4075 vx_convert_from_virtual): If target does not have floating point,
4076 zero register "values", and avoid doing cross-net conversions.
4077 (vx_lookup_symbol): Rename net_lookup_symbol, add to vectors.
4078 (vx_open): Rearrange code that attaches to target and reads
4079 symbols for all loaded modules, to work if some of the modules
4080 are not accessible. Add symbol_stub() and add_symbol_stub()
4081 as callbacks from catch_errors(). Allow connect attempt to be
4082 interrupted painlessly with ^C (FIXME, there are still some bugs
4083 if the interrupt happens during symbol reading.). Print
4084 final message with puts_filtered, since symbol messages are
4089 * main.c (catch_errors): Only print errstring if non-null.
4090 (command_loop): Avoid an ioctl per command to test ISATTY.
4092 * remote-vx.c (net_load): make static; avoid sophomoric msg.
4093 (vx_xfer_memory): Return correct result!
4094 (vx_files_info): Indicate whether target has float or not.
4095 (vx_lookup_symbol): Complain, not error, if target gone.
4096 (vx_open): Print "Connected" msg before disabling immediate-quit.
4097 [FIXME: lookup_symbol and vx_open changes need testing.]
4099 target.c, remote-eb.c, inftarg.c, am29k-opcode.h, target.h,
4100 tm-29k.h, tmm-vxworks68.h, symfile.c, gdb-int.texinfo: Add
4101 contributor lines and update copyrights to 1991.
4103 Changes from an attempted H-PUX host port:
4105 * infptrace.c (PT_ATTACH, PT_DETACH): Handle HP/UX, which
4106 defines PT_ATTACH and PT_DETACH but not PT_KILL.
4107 * remote-eb.c (eb_open): Misplaced endif kills sysv H/PUX.
4108 * remote-vx.c: include <sys/time.h> for HPUX.
4109 * hp300hpux-xdep.c (fetch_core_registers): Rewrite old
4110 "core_file_command" routine to BFD regime. May not work yet.
4112 Attempted port of "gdb-3.4 Van Jacobson xgdb" to modern gdb.
4114 * xgdb.c: Replace X10 version with some VJ version.
4115 (FIXME: Its copyright assignment is not on record.)
4116 * xgdb.c: Update include files to X11R4 (Xaw crud).
4117 (xgdb_display_source, create_text_widget): fix call to
4118 get_filename_and_charpos. Rewack source window stuff for X11R4
4119 (gleaned from include files, and "nm's" of binary libraries, since
4120 I had no doc available).
4121 (append_selection, append_selection_word): Disable with FIXME
4122 since R4 changed interface here.
4123 (create_buttons): Add back the old set of buttons.
4124 (xgdb_create_window): Fix call to XtInitialize (&argc not argc).
4126 * Makefile.dist (xgdb, xgdb-init.c): Update for X11R4 on Suns.
4127 Roll VERSION to 3.94 (not yet final though).
4129 Sat Feb 9 09:46:25 1991 John Gilmore (gnu at cygint.cygnus.com)
4131 * obstack.h (obstack_ptr_grow, obstack_ptr_grow_fast,
4132 obstack_int_grow, obstack_int_grow_fast): Eliminate
4133 cast on left of assignment, which gives MIPS cc fits and is
4136 * sparc-pinsn.c (print_insn): Eliminate 'set' test, subsumed by
4137 F_ALIAS. Use printf, not fprintf, when not passing a file
4139 (compare_opcodes): Check that identical instructions have
4140 identical opcodes, complain otherwise.
4142 * sparc-opcode.h (st %fsr): Fix opcode "lose" mask. This
4143 was reported by Roland McGrath.
4144 (unimp): Only match if exactly zero instruction. (Roland)
4145 (branches and traps): Generate all variations of these
4146 instructions with macros, based on a single call that defines
4147 each condition name and its binary representation.
4148 (set): Turn on alias bit, to avoid test in sparc-pinsn.c.
4150 * valprint.c (val_print_fields): Take, and use, format parameter.
4151 This means that "p/x struct" again prints the elements in the
4152 desired format. Changed callers.
4154 * stack.c (frame_info): Use filtered output, and indicate wrap
4155 points. Remove kludgy formatting designed to avoid line wrap.
4157 * utils.c (wrap_here): If the line is already full (because
4158 we had printed a long indent or long wrapped string), do an
4159 immediate newline-and-indent.
4161 * m68k-pinsn.c (print_insn_arg): Bugfix from
4162 ntmtv!thompson@ames.arc.nasa.gov (Mike Thompson): 'bkpt #0'
4163 instruction is incorrectly disassembled as bkpt #8.
4165 * dbxread.c (end_psymtab): Bugfix from Peter Schauer
4166 <pesrem@regent.e-technik.tu-muenchen.de>: If you want to set a
4167 breakpoint in a *.y file gdb will say Reading in symbols for *.y...
4168 and then will dump core (sometimes). I traced it back to an
4169 uninitialized symfile_name in psymtab_to_symtab.
4170 (const_vol_complaint): Add quotes to message.
4171 (define_symbol): Only believe line number if gcc_compiled.
4172 Avoid allocating symbol if we will not return it.
4174 Add target strata support so that newly established targets go
4175 into their right place in the target stack (e.g. a new exec file
4176 doesn't wipe out the ability to access the running process).
4178 * target.h, core.c, exec.c, inftarg.c, remote-eb.c,
4179 remote-nindy.c, remote-vx.c, remote.c, target.c: Add to_stratum
4180 and initialize it properly in all the targets.
4182 * target.h: Document strata. Change return type of push_target.
4184 * target.c (nomemory): new function for dummy memory access.
4185 (tcomplain): Rename complain, now also used in symfile.c.
4186 (push_target): Push targets within strata. New return value shows
4187 whether new target is on top of stack or not. Always keep dummy
4189 (target_files_info): Ignore dummy target.
4191 * core.c (core_open): Warn user, and skip accessing file, if the
4192 core target is not the topmost target in the stack.
4193 * remote-nindy.c (nindy_create_inferior): Avoid unpush_target, now
4196 * remote-vx.c: Remove vx_prepare_to_store from vxworks memory
4197 target_ops, it doesn't belong there since we have no regs there.
4198 Change name of target from machine => memory to clarify.
4200 Thu Feb 7 16:32:09 1991 John Gilmore (gnu at spiff.cygnus.com)
4202 * Freeze version 3.93 for release.
4204 * Makefile.dist: Handle vx-share and nindy-share subdirs
4205 properly when building gdb.tar.Z.
4207 * symtab.c: lint; add no_symtab_msg to consolidate the messages
4208 printed in various places, so I could change just one copy.
4210 * dbxread.c, coffread.c: Change references to bfd->iostream
4211 to cast to FILE *, now that BFD avoids needing types defined
4212 in other header files.
4214 Tue Feb 5 21:39:35 1991 John Gilmore (gnu at cygint.cygnus.com)
4216 * command.c, dbxread.c, expprint.c, infcmd.c, infptrace.c,
4217 infrun.c, printcmd.c, remote-nindy.c, source.c, sparc-tdep.c,
4218 sparc-xdep.c, symfile.h, symmisc.c, utils.c, valprint.c: Lint
4219 (actually gcc -Wall).
4221 * dbxread.c: Remove first_global_sym, last_global_sym, since
4222 they are never referenced.
4224 * defs.h (baud_rate): Declare.
4225 main.c: Define it, and add the -b option to set it.
4227 * gdb-int.texinfo: Add text on how to define a new host or target
4228 architecture, prompted by Per Bothner's questions about MIPS
4231 * gdb.texinfo: Document "complaints". Change doc of -q since
4232 gdb no longer prints the copyright and blurb if you specify a file
4233 name to be debugged (just like Emacs). Add doc for Nindy-specific
4234 command line flags for specifying target serial port and such.
4235 Update copyright to 1991.
4237 * gdbcore.h: Remove a large mass of now-useless crud, since BFD
4238 has taken over for us the job of ripping up executable files. The
4239 crud caused Per Bothner's port to not compile.
4241 * infrun.c (normal_stop): Avoid printing "Program exited
4242 normally" if we are in batch mode. This allows a GDB which
4243 executes a program on a target system, to behave like a Unix
4244 command (input from stdin, output to stdout, no extraneous
4247 * main.c (main): Allow additional machine-dependent command line
4248 options to be specified with the ADDITIONAL_OPTIONS,
4249 ADDITIONAL_OPTION_CASES, ADDITIONAL_OPTION_HELP, and
4250 ADDITIONAL_OPTION_HANDLER macros. Also allow machine-dependent
4251 processing to occur just before the main loop with
4252 BEFORE_MAIN_LOOP_HOOK.
4253 (main): If a "core file" argument is specified, and it is not a
4254 core file, try it as a process ID to attach.
4255 (symbol_completion_function): Attempt to cope with
4256 "show screen-" TAB, not very successfully. This needs more work,
4258 (batch_file): New function, returns whether we are reading
4259 commands from an interactive tty on stdin, or from somewhere else.
4260 Called by normal_stop since it doesn't get from_tty passed down
4261 to it like many commands do.
4263 * remote-nindy.c: Handle command line options for nindy
4265 (nindy_before_main_loop): Prompt user for tty name if they
4266 don't specify it before getting to the interactive command loop.
4268 * tm-i960.c: Add ADDITIONAL_OPTIONS, etc, to handle -O, -brk,
4269 and -r command line options. Also add hook before main loop
4270 to make it easy to specify a tty.
4272 * TODO: More things to do, one done.
4274 Mon Feb 4 23:57:39 1991 John Gilmore and Mike Tiemann (at cygint.cygnus.com)
4276 * dbxread.c: Make complaint() calls pass pointer, not struct.
4277 Add complaints about badly formatted C++ type information
4278 (const/volatile indicator, and parse errors resulting in
4279 error_type). Fix C++ virtual member fn comment.
4280 (read_struct_type): Avoid bumping pointer if we got a parse
4281 error; this prevents our walking beyond the end of a string.
4282 Terminate loop on null char as well as semicolon.
4283 (process_one_symbol): Fix the LBRAC fix so that it uses the
4284 last previous SLINE, FUN, or SO record's PC address. C++ debug
4285 symbols did not have SLINE records in a useful order compared
4286 to the LBRAC records.
4287 (define_symbol): Handle "catch" records.
4289 * symtab.c (check_stub_type): Added new complain
4290 `stub_noname_complain' and added a consistency check to
4291 keep the debugger from crashing when finishing from an
4292 exception frame. A real fix will be needed later.
4294 Sat Feb 2 10:43:05 1991 John Gilmore (gnu at cygint.cygnus.com)
4296 * infcmd.c (attach_command): Make global.
4298 * Makefile.dist (REMOTE_OBS): Make these compile by default,
4299 but make them easy to comment out. Perhaps later they should
4300 be enabled by what CPU you configure for? FIXME.
4301 (VERSION): Roll to 3.93.
4302 (pinsn.o): Remove rule for obsolete file.
4303 (dbxread.o,coffread.o,mipsread.o): Use ${srcdir} explicitly.
4305 Run down a problem that manifested by printing the wrong function
4306 name in stack traces of read_ofile_symtab. Turned out that the
4307 problem was the SunOS 4.1.1 (and previous) C compiler outputs
4308 the LBRAC symbol with an address in the *data* segment, which
4309 blew our binary search through the blocks.
4311 * dbxread.c: Use the complain() facility consistently to bitch
4312 about problems in the symbol file we are reading.
4313 (finish_block): Add code to check the nesting of the blocks;
4314 complain and Procrust them to fit if wrong.
4315 (make_blockvector): Check the order of the blocks, complain
4316 [but don't cope] if wrong.
4317 (process_one_symbol): ifndef SUN_FIXED_LBRAC_BUG, check LBRAC
4318 symbols to be sure their PC value is greater than the last SLINE
4319 (line number) symbol we've seen, complaining and adopting the
4320 SLINE PC value if wrong.
4322 * symfile.h (struct complaint, complaint_root, complain,
4323 clear_complaints): Add.
4324 * symfile.c (complain, complaint_root, clear_complaints): Add
4325 facility to deal with non-fatal complaints and to regularize their
4327 (symbol_file_add): Clear complaint counters to allow new complaints.
4328 (initialize_symfile): Add 'set complaints' and 'show complaints'.
4330 * dbxread.c (dbx_symfile_read): Remember the address and size
4331 of the string table for the main symbol file, so we won't read it
4333 (dbx_psymtab_to_symtab): Fix the check for main symbol file,
4334 to avoid reading the string table yet again. Lint.
4335 (throughout): Improve filtered output, including word wrap.
4336 (read_range_type): Improve Bothner's fix to handle other types too.
4338 * utils.c: Improve line wrap implementation. Handle unlimited
4339 width by making chars_per_line unsigned.
4340 (puts_filtered): New, easy, function.
4342 * defs.h (puts_filtered): add.
4344 * mipsread.c (compare_symbols, sort_symtab): Remove these fns,
4345 call the identical sort_symtab_syms() in symfile.c instead.
4347 * expread.y: Suggest the `file' command rather than `symbol-file'.
4349 * command.h (enum var_types): Add zinteger for seroable
4351 * command.c (do_setshow_command): Handle var_zinteger. Restructure
4352 nested if's into a switch.
4354 * breakpoint.c (bpstat_print): If bpstat "print" flag is not set,
4355 we did not stop because of a breakpoint (it must have been for
4356 some other reason, like a "stepi"), so don't print anything.
4358 * symtab.c: Include <sys/types.h> all the time. Now that BFD
4359 doesn't include <sys/types.h>, old SunOS's require it for
4362 Sat Feb 2 10:39:15 1991 Per Bothner (bothner@cs.wisc.edu)
4364 A test port of gdb-3.92.6 to the Sony NEWS.
4367 Don't normally link in remote- or vx stuff.
4368 Some of it doesn't compile, and it wastes space for 99% of the users.
4369 Remove reference to no-longer-used HAVE_VPRINTF.
4370 Fixed BFD_DEP typo to BFD_DIR.
4372 Fix cast in arg to bfd_h_getlong.
4373 Make char *prefix be const.
4374 Fix how certain range types are mapped into builtin unsigned int types.
4376 Remove 2 #includes. They cause errors (on Sony, at least),
4377 and aren't needed (they wern't in earlier versions).
4379 print_address_symbolic should never demangle labels
4380 (since it prints *assembler-level* labels).
4382 [This was superseded by the change to printcmd below.]
4385 Add some "volatile" return types to avoid warnings.
4386 If MISSING_VPRINTF add vprintf function and not just macro
4387 (since vprintf is used in printcmd.c).
4389 Unless __GNUC__, use obstack_grow instead of obstack_ptr_grow.
4390 (The latter isn't grokked by some PCC-based compilers.)
4392 [This change is in abeyance, we prefer to fix obstack_ptr_grow.]
4394 Make chunk size of dont_print_obstack 32*4 instead of default 4096.
4395 * nindy-share/coffstrip.c
4396 Added some forward declarations (otherwise, gcc complains
4397 about implicit extern redefined as static).
4399 Sun Jan 20 02:38:19 1991 John Gilmore (gnu at cygint.cygnus.com)
4401 Changes inspired by Per Bothner:
4402 * printcmd.c (print_address_symbolic): Take additional parameter
4403 specifying whether to demangle.
4404 (print_address): Pass in asm_demangle to control demangling.
4405 (print_address_demangle): New fn, takes explicit arg to control
4407 * utils.c: Add new vars demangle and asm_demangle, and let them
4409 (fputs_demangled): If !demangle, just print the argument.
4410 (fprint_symbol): If !demangle, just print raw symbol.
4411 * valprint.c (val_print): Call print_address_demangle rather than
4412 print_address, to cause demangling to depend on the global
4413 rather than assembler-level demangling setting.
4414 * WHATS.NEW, gdb.texinfo: Document.
4416 * main.c (show_command): Show all settings if no arg.
4417 (initialize_main): Make "info set" the same as naked "show".
4418 * command.c (cmd_show_list): Handle prefix commands in the
4419 list, and print the name of the setting as well as its English
4420 description and value.
4422 Allow gdb functions to specify where a line should wrap if it
4423 exceeds the size of a terminal line. Use it to make the output
4425 * utils.c (set_screen_width_command): New fn, mallocs a buffer
4426 of the right size when screen width changes.
4427 (set_screensize_command, screensize_info): Remove #if 0'd fns.
4428 (wrap_here): New fn, indicates a point in the output where we
4429 should wrap the line rather than just letting it overflow at a
4431 (fputs_filtered): Implement wrapping.
4432 (n_spaces): New fn, returns a pointer to N spaces.
4433 (print_spaces_filtered): Use n_spaces.
4434 * defs.h (n_spaces): Declare.
4435 * stack.c (print_frame_info): Wrap with 4-space indent after
4436 fn name and before filename and line number.
4437 * printcmd.c (print_frame_args): Wrap with 4-space indent
4438 before each argument name is printed.
4439 * valprint.c (value_print): Wrap with no indentation before
4441 (val_print_fields): Wrap with indentation relative to nesting
4442 level before each field name.
4443 (val_print): Wrap with nesting indentation before array elements.
4444 * command.c (do_setshow_command): Avoid extra newlines,
4445 wrap with 4-space indent around values printed, end with period.
4446 * WHATS.NEW, gdb.texinfo, gdb-int.texinfo: Document.
4448 * breakpoint.c (breakpoint_1): Implement addressprint for
4449 "info breakpoints" display. Change file name and line number
4450 format to " at file:nnn" rather than " (file line nnn)".
4451 * gdb.texinfo: Document.
4454 Fri Jan 18 07:21:25 1991 John Gilmore (gnu at cygint.cygnus.com)
4456 Frozen for gdb-3.92.6 release.
4458 README, WHATS.NEW: Update for 3.92.6 release.
4460 tconfig/{altos, i386v, i386v32, m88k, umax}: Eliminate
4461 coffread.o from configs since it is now built by default.
4462 tconfig/{3b1, altosgas, arm, convex, hp300bsd, hp300hpux,
4463 i386v-g, i386v32-g, isi, merlin, news, news1000, np1, pn,
4464 pyramid, symmetry, vax, vxworks68}: Eliminate dbxread.o
4465 from configs since it is now built by default.
4467 Makefile.dist: Update for release 3.92.6. Handle files that
4468 have been moved to ../include, ../getopt, or ../bfd. Add
4469 saber.suppress and tests directory. Add config.status to
4470 the release (it will say "none").
4472 coredep.c: Minor formatting fixes.
4474 These changes were made in early December but only checked in now:
4475 * nindy-share/Onindy.c, nindy-share/coffstrip.c,
4476 nindy-share/nindy.c: lint
4477 * nindy-share/nindy.c (ninStopWhy): Don't byteswap the
4478 register values coming back from the target; we store values
4479 in target byte order everywhere.
4481 Wed Jan 16 19:01:37 1991 John Gilmore (gnu at cygint.cygnus.com)
4483 * am29k-opcode.h, am29k-pinsn.c: Add 29050 opcodes.
4485 * valprint.c (cplus_val_print, val_print_fields): New functions,
4486 which print C++ objects. They conspire to avoid printing a
4487 virtual base class more than once, following all the twists and
4488 turns of C++ virtual base rules.
4489 (val_print): Call the above rather than do it by hand.
4491 * symfile.c (symbol_file_add): Only reset symfile_mtime for main
4492 symbol file, not for added files like shared libs. This really
4493 needs to be generalized to a timestamp per file.
4495 * core.c (cleanup_core): Avoid coredump if no core file.
4497 * config.gdb: Accept -host or -target in place of +host or
4500 * coffread.c (find_linenos): Avoid desupported BFD interface
4501 to line numbers. We still read them manually rather than using
4502 BFD's "generic" features.
4504 * gdbrc.tex, threecol.tex: Add GDB reference card and its
4506 Makefile.dist: Add refcard to OTHERS list for creating tar files.
4508 * Makefile.dist: Eliminate use of $< in explicit targets.
4510 * readline/Makefile: Use $< rather than $*.c, which does not
4511 include the VPATH in GNU Make.
4513 * tconfig/i960-bout, tconfig/i960-coff: These are identical
4514 copies of tconfig/i960, added for global configuration
4515 compatability. All i960 versions can read both coff and b.out.
4517 * tm-88k.h: Fix multiline macro that lacked \'s. Remove
4518 COFF_FORMAT and COFF_CHECK_X_ZEROES since these are now handled
4521 * TODO: Think of more things to do.
4523 Wed Jan 2 19:09:29 1991 John Gilmore (gnu at spiff.cygnus.com)
4525 tconfig/{am29k,i960,sun2*,sun3*,sun4*}: Eliminate config
4526 of sdb versus dbx debug symbols. Add kludge for 68881 80-bit to
4527 64-bit float conversion.
4529 tconfig/sun4, tconfig/sun3, xconfig/sun4, xconfig/sun3: Make
4530 equivalent to sun?os4 so global config works.
4532 Wed Jan 2 18:20:51 1991 John Gilmore (gnu at spiff.cygnus.com)
4534 Fix from Eberhard Mattes <mattes@azu.informatik.uni-stuttgart.de>
4536 * main.c: Only declare linesize once; declare pagesize not at
4537 all, since it is never used.
4538 (main): Clear newly allocated line before it is used.
4540 Fri Dec 28 00:13:42 1990 John Gilmore (gnu at cygint)
4542 Further stabilization for the Intel 960.
4544 * Makefile.dist: Parameterize the location of the "include"
4545 and "bfd" directories, as well as "getopt". Add symfile.c.
4546 Link in both dbxread and coffread. Fix up "make depend" to
4547 rewack the locations of include, bfd, and getopt in its output.
4549 * README: Document moving include files, improve some of
4552 * coffread.c: Move common code out to symfile.c. Change
4553 symbol_file_command style interface to use new *_symfile_init
4554 and *_symfile_read interface under BFD. Use BFD internal
4555 info to locate line table, symbols, etc.
4557 * core.c (core_fetch_registers): Rename to get_core_registers
4558 to avoid confusion with fetch_core_registers.
4559 (register_addr): Move to coredep.c, which is already machine
4560 dependent. This leaves core.c pretty clean of dependencies.
4562 * coredep.c (register_addr): Accept this routine from core.c.
4564 * dbxread.c: Move common code (with coffread.c, etc) into new
4565 symfile.c. Each psymtab now contains a pointer to the
4566 format-dependent function that knows how to read it in. Make
4568 (dbx_psymtab_to_symtab): Renamed from psymtab_to_symtab_2.
4569 (process_one_symbol): Add code to complain about a "compiler bug
4570 we muzzle here", if we actually see it.
4572 * eval.c (evaluate_subexp): Insert missing "break" statements
4573 in code that determines whether a variable is an lvalue in
4574 memory, register, or whatever. I detected this via a compiler
4575 bug in which it *almost* mashed out the whole switch statement.
4577 * gdb-int.texinfo: Add minor sections on configuring gdb for
4578 release, and about the README file.
4580 * infcmd.c (registers_info): Fix formatting somewhat. Still
4581 not as pretty as before, but it handles byte swapping.
4583 * remote-nindy.c: If data cache routines are interrupted while
4584 waiting for the remote end, be sure that any uninitialized cache
4585 blocks are on the free list, not on the valid list!
4587 * symfile.h: Flesh out this header file with all the various
4588 routines and variables that have been merged in from dbxread.c
4589 coffread.c, and symtab.c to symfile.c.
4591 * symfile.c: New file, containing code common to dbxread.c,
4592 coffread.c, and some code from symtab.c. All generic code for
4593 reading symbol files should be in here now.
4594 (unrecord_misc_function): Remove unused function.
4596 * symtab.h: Remove file-reading things to symfile.h.
4598 * symtab.c: Remove file-reading things to symfile.c.
4600 * tm-i960.h: Fix FRAME_CHAIN types; define PRINT_RANDOM_SIGNAL
4601 to decode i960 fault types.
4603 * target.h, remote.c, remote-eb.c, remote-vx.c, remote-nindy.c,
4604 target.c: Change type of the "resume" function from int to void,
4605 since its result was never used.
4607 Sat Dec 22 02:51:40 1990 John Gilmore (gnu at cygint)
4609 * main.c: Replace "stupid" with "caution"; you now "set caution
4612 * printcmd.c (print_scalar_formatted): Fix typo in 'g' format
4614 * infcmd.c (do_registers_info): Call val_print to deal with the
4615 byte order of the registers being printed. FIXME, this makes
4616 the formatting of the output uglier.
4618 * infcmd.c (wait_for_inferior): If PRINT_RANDOM_SIGNAL is
4619 defined, call it for signals the debugger doesn't itself use.
4620 The i960 uses this for more detailed fault information.
4622 * remote.c (remote_open): If arg is null, print help rather than
4625 * sparc-xdep.c (register_valid): Avoid declaring size, since
4626 various modules will think of various sizes depending on the
4627 architecture of their tm-file. FIXME, we need protection against
4628 actually entering one of those modules, which would clobber
4629 storage if not for the target architecture compiled into gdb.
4631 * stack.c (up_command, down_command): Always print the frame
4633 (up_silently_command, down_silently_command): New commands
4636 * i960-pinsn.c (reg), i960-tdep.c: Lint.
4638 * i960-tdep.c (i960_frame_chain_valid): Lookup_symbol now takes
4639 more parameters than it used to.
4641 * findvar.c (registers): Increase slop to 256 bytes, which should
4642 protect us against even most RISC machines with large register
4644 (locate_var_value): Move declaration inside related ifdef.
4646 * remote-nindy.c (): Use TIOCSETN rather than TIOCSETP
4647 throughout, to avoid throwing away buffered input from the board.
4648 (nindy_wait): Supply_register takes addr_of_value, not value.
4649 (i960_print_fault): Renamed from i80960_fault.
4650 (nindy_fetch_registers): Avoid have_regs stuff, just get them.
4651 (nindy_store_registers): Avoid regs_changed stuff, just stuff
4653 (nindy_create_inferior): Don't bother to write PC_REGNUM since
4654 we can set the PC in the call to proceed(). Unpush nindy_ops
4655 before pushing it on top, to avoid message to user. Eliminate
4656 commentary from Unix machines that just misleads here.
4657 (reset_command): Fix error message to suggest target command.
4659 Wed Dec 19 11:03:56 1990 John Gilmore (gnu at cygint)
4661 Release 3.92.5 as frozen.
4663 Stabilize the merged release...with help from lint, Saber C,
4666 Everywhere: Add include files needed to declare return types
4667 of functions called.
4669 * gdb.texinfo: Roland Pesch is documenting gdb, glory be!
4671 * breakpoint.h: Add undeclared breakpoint functions, and some
4672 functions for display handling since I couldn't think of a better
4675 * breakpoint.c (insert_breakpoints): Make code for disabling
4676 shared library bkpts more likely to work. It's used when we
4677 rerun a program and stop before the shared library has been
4679 (breakpoint_cond_eval, bpstat_stop_status): Pass arg as int,
4680 cast from pointer, so it squeezes through catch_errors.
4681 (bpstat_stop_status): Fix logic broken some time ago. We now
4682 always create a bpstat if the stop address matches a breakpoint,
4683 even if we don't stop there -- just like the old code used to do
4684 before I got my fingers into it (sigh).
4685 (breakpoint_1): Print "ignore count" after "stop only if"
4686 condition, since that's how it actually works.
4687 (mention): Handle watchpoints as well as breakpoints.
4688 (watch_command): use set_raw_breakpoint and mention to do most
4689 of the work (and initialize all the fields!). Only pass one
4690 arg to parse_c_expression, since that's all it takes.
4692 * command.c (not_just_help_class_command): Rename arg to args
4693 since we ignore "unused argument" warnings on vars named "args".
4694 inflow.c (child_terminal_info): ditto.
4695 infptrace.c (kill_inferior): ditto
4696 main.c (catch_errors, version_info, quit_command, pwd_command,
4697 source_command, dump_me_command, editing_info,
4698 set_history_size_command, set_history, show_history,
4700 stack.c (locals_info): ditto
4701 target.c (target_files_info): ditto
4702 valprint.c (set_input_radix, set_output_radix): ditto
4704 * core.c: Remove old variables for handling core and exec file
4705 sections (data_start, data_end, stack_start, stack_end,
4706 reg_stack_start, reg_stack_end, reg_stack_offset, text_start,
4707 text_end, exec_data_start, exec_data_end, text_offset,
4708 exec_data_offset, data_offset, stack_offset). They're
4709 superseded the more general build_section_table and
4711 (get_exec_file): Mention the `file' command.
4712 (read_memory_check): Rename to memory_error, and only call it
4713 in the case of an actual error.
4714 (read_memory, write_memory): call memory_error.
4715 (core_fetch_registers): Register section name is ".reg".
4717 coredep.c: Remove a bunch of crud now that all this file does
4718 is pull the registers out of a core file.
4719 (fetch_core_registers): Rewrite to actually work, I hope.
4721 dbxread.c: Use a.out.gnu.h, not system a.out, now.
4722 Replace index() with strchr(). Remove all the pre-BFD macro
4723 definitions for accessing the symbol file.
4724 (struct dbx_symfile_info): Encapsulate the information that
4725 dbx_symfile_init needs to pass to dbx_symfile_read in this
4728 (dbx_new_init, dbx_symfile_init, dbx_symfile_read,
4729 dbx_symfile_discard): Rearrange symbol file reading to divide
4730 the format-specific part from the format-independent part,
4731 leaving the format-independent part such as file name expansion
4732 and opening in symtab.c. This replaces
4733 partial_symbol_file_open and partial_symbol_file_read.
4734 Symbol_file_read, add_file, add_file_target_command,
4735 add_file_addr_command move to symtab.c. Pass an explicit
4736 "mainline" flag for when reading the main symbol table, rather
4737 than relying on the offset address to be zero or nonzero.
4739 (dbx_symfile_read): Don't allow void *'s to be printed as
4741 (SWAP_SYMBOL): Use bfd routines to byte-swap the symbols.
4742 (ADD_PSYMBOL_TO_LIST): Make the "function call rather than
4743 macro" debug version really work.
4744 (read_dbx_symtab): Remove unref'd parameter inclink.
4745 Avoid swapping N_SLINE symbols, for speed.
4746 Merge N_TEXT!N_EXT case with the other external symbol
4747 definitions' case. Add comments.
4748 (start_psymtab): Allocate the symfile name in the psymtab on
4749 the psymbol_obstack, rather than using the caller's storage.
4750 (end_psymtab): Only allocate a dependencies list if there are
4752 (psymtab_to_symtab_2): Use BFD when reopening file to read
4753 its symbols for real.
4754 (read_struct_type): Add FIXME comments where it needs work
4756 (read_huge_number): Add FIXME about overflows.
4757 (read_range_type): Add FIXME about comparing a long to 1<<32.
4759 * coffread.c: Minor changes to move things closer to the new
4760 regime with symtab.c and dbxread.c Major work is still needed
4763 * exec.c (exec_file_command): Remove old variables (see core.c
4765 (xfer_memory): If memory transfer is right at the end of a
4766 section, don't lose.
4768 * findvar.c (get_saved_register): If value is in a real
4769 register, LVAL is lval_register, not lval_memory.
4771 frame.h: Declare print_sel_frame and record_selected_frame.
4773 gdb-int.texinfo: New file, for GDB internals documentation.
4774 Very simple, unformatted doc of cleanups is there for now.
4776 gdbcore.h: Remove obsolete variables that described a.out
4777 section addresses and offsets. (See core.c above.)
4778 Declare fetch_core_registers and registers_fetched.
4780 getopt.c: Declare char *alloca(); even on SPARC.
4782 infcmd.c (run_command): Call target_kill rather than
4784 (step_command, next_command, stepi_command, nexti_command):
4785 Declare from_tty parameter even though we don't use it.
4786 (run_stack_dummy): argument BUFFER is a char array, not
4787 a pointer to REGISTER_TYPE.
4788 (finish_command): using_struct_return needed a value *,
4789 not a struct symbol *.
4791 * infptrace.c (child_xfer_memory): To avoid dependency on
4792 where sections are in memory, try PT_WRITE_D and if that fails,
4793 try PT_WRITE_I. Most Unixes don't care which you use.
4795 * infrun.c (step_resume_break_shadow): Change to array to
4796 match other breakpoint shadow storage.
4797 (clear_proceed_status): Pass address of bpstat to
4798 bpstat_clear, not the bpstat itself.
4799 (child_create_inferior): FIXME comment about if the child
4801 (start_inferior): Remove old function.
4802 (child_open): Use target_kill rather than kill_inferior.
4803 (wait_for_inferior): Ditto.
4804 (insert_step_breakpoint, remote_step_breakpoint): Use
4805 new step_resume_break_shadow.
4807 * inftarg.c (child_wait): If all child processes die,
4808 pretend that the one being waited for exited with signal 42.
4810 * main.c (command_line_input): When scanning for comments,
4811 don't coredump on unclosed quotes.
4812 (quit_command): Use target_kill rther than kill_inferior.
4813 (_initialize_main): Rename class_user from "user" to
4816 * printcmd.c (print_command_1): Initialize "fmt" if no format
4817 is specified by the user.
4818 (print_frame_args): Only add to args_printed if we are
4819 actually fetching args from the stack (avoiding undefined
4821 (_initialize_printcmd): Remove bogus \{ from string.
4823 * remote-eb.c (eb_open): Avoid coredump on no argument.
4825 * remote-nindy.c: Bring out of Intel environment into new
4826 target environment. Remove all conditional compilation on
4827 I80960. Massive hacking throughout.
4828 (nindy_xfer_inferior_memory): New routine stolen from
4830 (nindy_create_inferior): New routine pieced together, probably
4831 not quite working yet.
4832 (nindy_ops): New target_ops struct for nindy.
4834 * remote-vx.c: Use write_memory rather than target_write_memory
4835 to get error checking.
4836 (vx_add_file_command, vx_open): Use symbol_file_add rather than
4838 (vx_create_inferior): Use target_terminal_ours...
4840 * signame.c (_initialize_signame): Always initialize, since
4841 we need the table for things other than psignal.
4843 * solib.c (solib_add): Use symbol_file_add, not add_file.
4844 (solib_address): Return boolean result rather than struct
4845 pointer which nobody else knows the type of.
4847 * sparc-tdep.c, valops.c: Use write_memory rather than
4848 target_write_memory, to get error checking.
4850 * stack.c (locals_info, catch_info, args_info,
4851 get_selected_block, frame_command, up_command): Use
4852 target_has_stack, rather than have_inferior_p or
4855 * sun3-xdep.c (fetch_core_registers): Rewrite for new BFD regime.
4857 * symfile.h: New file, defining the interface between the
4858 generic and object-file-specific symbol reading code.
4860 * symtab.c: Move generic symbol-reading interface to symtab.c,
4861 from dbxread.c, coffread.c, mipsread.c, etc. Add symtab_fns
4862 table to map BFD targets to symbol-reading modules in GDB.
4863 Change index to strchr.
4864 (lookup_struct_elt_type): Use error() rather than hand-made
4865 simulations thereof.
4866 (lookup_partial_symbol): Speedup slightly when length == 0.
4867 (symbol_file_add): New function.
4868 (symbol_file_command): Call it.
4869 (symfile_open, symfile_init): New function.
4870 (add_file_target_command, add_file_addr_command): moved from
4873 * target.c (target_command): use target_kill.
4875 * target.h (target_files_info): Don't declare, never called
4878 * tm-sun2.h, tm-sun3.h (STACK_END_ADDR): Use system include
4879 files to determine stack end address.
4881 * valarith.c (value_x_binop, value_x_unop): Change error message
4882 to be more useful. Pass proper argument to value_struct_elt.
4884 * valops.c (value_assign): FIXME comment that long long
4885 bitfields will break here.
4887 * Makefile.dist: Add symfile.h, remote-nindy.c, remote-eb.c.
4888 Update `make saber_gdb' to work better.
4890 * TODO: A woman's work is never done.
4892 * cplus-dem.c, environ.c, inferior.h, infrun.c, inftarg.c,
4893 main.c, obstack.c, printcmd.c, remote-eb.c, remote-nindy.c,
4894 remote-vx.c, remote.c, solib.c, source.c, sparc-pinsn.c,
4895 sparc-tdep.c, sparc-xdep.c, symmisc.c, symtab.c, symtab.h
4896 target.c, terminal.h, tm-sparc.h, tm-sunos.h, utils.c,
4897 valops.c, valprint.c, exec.c: Lint.
4900 Wed Dec 12 23:44:15 1990 John Gilmore (gnu at cygnus.com)
4902 Continuing Intel 960 port merge of GDB.
4904 * Makefile.dist: Merge i960 "nindy-share" files. Rename
4905 malloc.h to gmalloc.h to avoid name conflicts in /usr/include.
4906 Don't ship gdb.dvi in tar file. Link gdb with init.o, not init.c.
4907 Wack over "make depend" so it handles files in subdirectories
4908 vx-share, nindy-share, bfd, and in the current directory.
4910 * blockframe.c (get_prev_frame_info): Remove fatal error
4911 if stack not defined.
4913 * core.c (core_open, core_detach): New functions that handle
4914 the old "core-file" command as "target core" and "detach" instead.
4915 (core_file_command): Call them.
4916 (core_xfer_memory): Use common routine xfer_memory.
4918 * dbxread.c: Include a.out.gnu.h, not system a.out.h.
4919 dbxread now uses bfd for everything but symbol reading itself.
4920 BFD internals are used to drag out the relevant file offsets.
4921 (partial_symbol_file_open): Change args all around for BFD.
4923 * symtab.c: Rename "value" to "val" everywhere, so we can
4925 (symbol_file_command): New command, moved from dbxread.c
4926 and coffread.c. It uses BFD to read the file, then vectors
4927 based on its type, to dbx or coff symbol readers.
4928 * symtab.h: Extern a few vars for symbol_file_command.
4930 * target.h: Breakpoint takes a char * save area, not a char **.
4932 * valprint.c (val_print): When unpacking bitfields, offset
4933 the address in gdb of the value, if it is declared with a shorter
4934 type. Remove the last "runtime kludge test" of host byte order.
4936 * utils.c: Remove old my_bfd_read routine.
4938 * stack.c (frame_info): Use target_has_stack. Print program counter
4939 register's actual name rather than "pc", since it's called the
4940 "ip" (instruction pointer) on the i960 (sigh).
4942 * target.c (target_command): Add command for selecting a target
4943 type and calling its open routine. This is used for initiating
4944 communication with a particular target, in a generic way.
4946 * tm-i960.h: Update for modern gdb. Remove semicolons from
4947 various macros. Handle reading struct return convention, and
4948 error-out attempts to return structs with the "return" command.
4949 Be sure gdb doesn't think we know how to call functions in the
4952 * i960-tdep.c: Rename FRAME_CHAIN_VALID and FRAME_FIND_SAVED_REGS
4953 to i960_xxx in lower case.
4954 (arg_address): Circumvent errors due to LOC_ARG_BLOCK
4955 not being defined yet.
4957 * remote.c (remote_open): Call start_remote to initialize
4958 wait_for_inferior during open.
4959 (remote_xfer_inferior_memory): Return length written rather
4962 * remote-vx.c (target_command -> vx_open): Use new generic
4964 * remote-eb.c, inftarg.c, exec.c: ditto.
4966 * infrun.c: Fix comments.
4967 (attach_program -> child_open): Use new generic target command.
4968 (wait_for_inferior): Clear saved register values before target_wait,
4969 so target_wait can set some of them if convenient.
4971 * infptrace.c (fetch_inferior_registers, store_inferior_registers):
4972 Return success indicator, not void.
4973 (child_xfer_memory): Avoid fetching initial word if we'll
4974 overwrite it anyway.
4976 * infcmd.c (attach_command): Use new generic target open routine.
4977 (_initialize_infcmd): Update doc on attach and detach commands.
4978 (do_registers_info): Merge in a byte-order problem as a FIXME
4981 * findvar.c (find_saved_register): Avoid problem in current frame.
4982 (read_relative_register): Ditto.
4983 (write_register): Convert byte order on the way out.
4985 * exec.c (file_command): Add.
4986 (add_to_section_table, exec_command): Use new bfd_map_over_sections.
4987 (xfer_memory): Common function between core_xfer_memory and
4989 (exec_xfer_memory): Use it.
4991 * pn-opcode.h: Document that a "PN" is a Gould PowerNode.
4993 * breakpoint.c, breakpoint.h, symtab.h, value.h, frame.h, utils.c,
4994 valops.c, stack.c, target.c, sparc-xdep.c, source.c, printcmd.c,
4995 infcmd.c, i960-pinsn.c, eval.c, defs.h: lint and gcc -Wall.
4997 Sun Dec 2 16:45:06 1990 John Gilmore (gnu at cygnus.com)
4999 Merge Intel 960 port of gdb, continuing...
5001 * dbxread.c (partial_symbol_file_open, partial_symbol_file_read,
5002 symbol_file_command): Pass from_tty arg to hush 'em up.
5004 * coffread.c (symbol_file_command): Avoid output if from_tty != 1.
5005 Add magic numbers for 960 COFF format.
5007 Fri Nov 30 09:18:20 1990 John Gilmore (gnu at cygnus.com)
5009 Merge Intel 960 port of gdb, from Intel "1.2" release.
5011 CHANGE_LOG entries from their port, which was based on
5014 Thu Sep 6 11:02:22 PDT 1990
5015 Remove temp file if download is interrupted.
5017 Wed Aug 1 09:08:33 PDT 1990
5018 Now uses binary protocol to talk to NINDY.
5019 Old hex protocol (NINDY 2.13 and older) supported with -O switch.
5020 Times out after 5 seconds when trying to talk to NINDY.
5022 Tue May 29 12:54:49 PDT 1990
5023 Added variable baud rate (-b switch).
5024 Source code reorganization.
5026 Thu Apr 26 11:09:55 PDT 1990
5027 More cleanup of batch mode; specifically, execute "-s", "-e", and
5028 "-se" switches as soon as they are encountered on the invocation line.
5030 Fri Apr 20 13:47:15 PDT 1990
5033 Thu Apr 19 09:54:28 PDT 1990
5034 Add 'reset' command.
5036 Wed Apr 18 09:48:07 PDT 1990
5037 After opening remote tty, wait for 1 second to go by without input
5038 from it before trying to talk to NINDY (fixes problems with the
5039 Heurikon HK80/V960E).
5041 Mon Apr 4 16:33:05 PDT 1990
5042 Some output was not being suppressed in 'batch' mode.
5044 Thu Mar 22 15:31:11 PST 1990
5045 Ask user if old symbol table should be deleted when new file is
5048 Allow user to run a program downloaded before gdb960 was brought up.
5050 Correct "exec-file" help message for i80960 context.
5052 Correct bug in calculating user space address: could occasionally
5053 corrupt user program.
5055 Make sure to zero low-order bits in rip's because of bug in 960CA
5056 A-step part: could cause operation faults when "next"ing across
5059 Correct bug that made it impossible to get source line numbers for
5060 code loaded at addresses higher than 0x7fffffff.
5062 Wed Jan 10 12:43:22 PST 1990
5063 Open remote tty for exclusive use.
5065 Fri Jan 5 12:14:42 PST 1990
5066 Correct disassembly (CA manual was right after all):
5067 opcode for sysctl is 0x659
5069 Mon Oct 23 12:03:04 PDT 1989
5070 Use G960BASE and G960BIN environment variables to find 'sx' utility.
5072 Mon Oct 16 14:15:09 PDT 1989
5073 "sfr0"-"sfr31" should have been named "sf0"-"sf31"
5075 Mon Oct 2 15:56:31 PDT 1989
5077 Added 960CA disassembly support.
5079 To simplify maintenance:
5080 - eliminated use of symblic links on pinsn.c: use i960-pinsn.c
5082 - eliminated opcode.h: incorporates tables into i960-pinsn.c
5083 - moved 960-specific routines from i960-pinsn.c to i960-md.c
5084 - made disassembly interface identical to that in gdmp960.
5088 Wed Nov 28 21:32:48 1990 John Gilmore (gnu at cygint)
5090 * target.h: Allow targets to stack. Add target_has_memory,
5091 _registers, etc. Restructure memory access and "info files"
5092 to walk the target stack.
5093 * exec.c, core.c, inftarg.c, remote.c, remote-vx.c, remote-eb.c,
5094 target.c: Change tables to match target.h.
5095 * inflow.c (child_mourn_inferior): pop child_ops.
5096 (generic_mourn_inferior): Use new has_stack flag.
5097 * infptrace.c (child_xfer_memory): New memory regime.
5098 * inftarg.c (child_files_info): New "info files" regime.
5099 * remote-eb.c: New memory regime, new info files.
5100 * remote-vx.c: New memory regime, new info files. Now use
5101 separate targets for VxWorks attachment to machine, and
5102 actually running a process under VxWorks, since one has
5103 stack & execution & regs and the other doesn't.
5104 * remote.c: New memory regime, new info files.
5105 * sparc-xdep.c (fetch_core-registers): New memory regime.
5106 * target.c: New routines and support for stacked targets,
5107 new memory regime, new info files regime.
5110 Generalize section handling for an arbitrary number of sections,
5111 including use of the new BFD (binary file) library.
5112 * gdbcore.h: Add struct section_table.
5113 * exec.c (build_section_table): Iterate all sections and
5114 record what gdb needs to know about them.
5115 (exec_command): Use it.
5116 (exec_xfer_memory): Use the table.
5117 (exec_files_info): Print the table.
5118 * core.c (core_file_command, core_xfer_memory, core_files_info):
5120 * source.c (find_source_lines): Use bfd_get_mtime.
5121 * dbxread.c: Quick changes to make it compile with new BFD.
5122 * utils.c (error): Avoid using bfd_error in generic routines.
5124 * core.c (core_fetch_registers): Get from the ".regs" section of
5126 * sparc-xdep.c (fetch_core_registers): Use the .regs info.
5128 * inferior.h (attach_flag): Export.
5129 * infcmd.c (run_command): use new target_create_inferior.
5130 * infrun.c (child_create_inferior): Don't return result.
5131 * Makefile.dist (VERSION): 3.91.4.
5133 Fri Nov 23 28:15:38 1990 John Gilmore (gnu at cygint)
5135 * breakpoint.c (bpstat_num): Handle breakpoints which have
5136 since been deleted, such as temporary breakpoints.
5137 infcmd.c (program_info): ditto.
5139 * core.c (core_file_command): Display the frame where the core
5144 * remote-vx.c (target_command): Merge in target command from
5145 targ-vx.c. A few other cleanups.
5147 * TODO, Projects: Lots more stuff to do...
5149 Fri Nov 23 18:15:38 1990 John Gilmore (gnu at cygint)
5151 Massive changes to wall off the remote-debugging interface
5152 behind a function vector. The port to handle VxWorks targets
5153 is also part of this.
5155 All files: Replace references to renamed functions,
5156 remove references to remote_debugging, remove references to
5157 have_include_file, have_core_file in favor of target_has_stack,
5158 target_has_memory, etc.
5160 * Modularize the breakpoint interface.
5161 breakpoint.h (BREAKPOINT_MAX): New define sets max length of
5162 a breakpoint instruction.
5163 breakpoint.c: struct breakpoint's shadow_contents now sized as
5165 (insert_breakpoints): Vector to target to install breakpoints.
5166 (remove_breakpoints): Vector to target here too.
5167 Remove REMOTE_SA_SPARC kludges and other remote_debugging.
5168 sparc-tdep.c (single_step): Use new breakpoint interface for
5169 the single-step breakpoints.
5170 mem-break.c (memory_insert_breakpoint, memory_remove_breakpoint):
5171 New file, contains routines to insert and remove breakpoints by
5172 reading out the old contents and later replacing them. This is
5173 how ptrace breakpoints work, and many remote systems as well.
5175 * tm-vxworks68.h: New config file, overrides a few things for
5176 Wind River's preferences.
5178 * target.h: New file, for transfer vector used to talk to the
5179 inferior (child, attached, core, exec, remote, etc). All accesses
5180 to the thing being debugged should come through these vectors.
5181 target.c: New file, routines to handle transfer vector.
5182 (various files): Add transfer vectors XXX_ops for the various
5183 targets and pseudo-targets (core files, etc) we support.
5185 * breakpoint.c (bpstat_stop_status): Further explorations of
5186 watchpoints and why things don't work all the time.
5187 (bpstat_alloc): New fn to allocate a bpstat and chain it.
5189 * config.gdb: Only add "source ${srcdir}/.gdbinit" to
5190 the local gdbinit if it doesn't already have it.
5192 * core.c (core_ops): add and install.
5193 Allow core debugging without exec file.
5195 * dbxread.c (free_and_init_header_files): Merge two fns.
5196 (end_symtab): Free named symbol table when a new version comes in.
5197 (read_dbx_symtab): Relocate all kinds of symbols with base
5198 address. First step toward handling different text, data, bss
5200 (add_file_addr_command): Renamed add_file_command.
5201 (add_file_command): Vector to remote handler.
5202 Add "load" as an alias for "add-file" command.
5204 * defs.h: Allow "volatile" to be used in non-ANSI; use it for
5205 non-returning functions.
5207 * exec.c: Add exec_ops, and push it as a target when an exec
5210 * infcmd.c (run_command): Pass executable file name and arg list
5211 separately when starting an inferior. Permit "run" when no exec
5212 file is specified, for VxWorks.
5213 (detach_command): Move to child_detach in inftarg.c.
5215 * inftarg.c: New file. Unix-child-specific routines, and the
5216 child_ops structure.
5218 * inferior.h (registers): Export "registers" as the way for
5219 target dependent register handlers to find gdb's local copy of
5220 the registers. Rename "stop_after_attach" to "stop_soon_quietly"
5221 since it is now used by places that want wait_for_inferior to
5222 handle the grunge but want to see every trap from the inferior.
5224 * inflow.c (create_inferior): Pull out, and merge into infrun.c.
5225 Eliminate remote_debugging hooks in terminal handling.
5227 * infrun.c: Replace start_inferior with child_create_inferior.
5228 Move all the hair of Unix shells and ptrace idiosyncracies into
5229 child_create_inferior, so remote handlers don't have to deal.
5230 Remove running_in_shell. Rename stop_after_attach to
5231 stop_soon_quietly, and use it in a few other places where we want
5232 to just call wait_for_inferior and get control back on the first
5233 trap. trap_expected now never takes a value > 1.
5234 (init_wait_for_inferior): Initialize static vars when a new
5237 main.c (gdbinit): Add new hook for .gdbinit file name, let
5238 it be overridden by config files as GDBINIT_FILENAME.
5239 (DEFAULT_PROMPT): Add new hook for overriding (gdb) prompt.
5240 Both of these are used for VxWorks gdb.
5242 mcheck.c: rename include file "gmalloc.c" to avoid problems
5243 with system include file "malloc.c".
5245 param-no-tm.h: New include file, same as param.h but does not
5246 include the default "tm.h" file. This is used in files where
5247 the target is known, e.g. remote-eb.c or sparc-xdep.c.
5249 param.h: Now just a shell that includes tm.h and param-no-tm.h.
5251 remote-vx.c: New file, VxWorks remote debugging support. Uses
5252 RPC routines that are shared with the target system, in directory
5255 remote.c: Vectorize remote interface.
5257 source.c: Globalize source_path, and make an alias "l" for "list"
5258 since we now have the "load" command.
5260 sparc-xdep.c: Use new param-no-tm.h.
5262 symmisc.c (free_named_symtab): Add new function from Wind River.
5263 However, ifdef it out for now while we think about what it should
5266 tm-sun3.h, xm-sparc.h, xm-sun3.h, xm-symmetry.h: Move
5268 the xm- file, and change its name to CHILD_PREPARE_TO_STORE, since
5269 non-Unix-children handle this with their own code in the target
5272 Makefile.dist: Roll version to 3.92.3. Add vx-share stuff to
5273 source and target lists. Add vx-share to default list of include
5274 directories. Add new files to src and target lists: mem-break,
5275 target, inftarg, remote-eb, remote-vx, targ-vx. Be sure the
5276 ${srcdir} versions of munch and createtags are used.
5278 * valops.c (find_function_addr): Split out of call_function.
5279 (call_function_by_hand): Rename call_function; this function
5280 calls functions in the target by laboriously patching the target
5281 word-by-word with the right stack, args, regs, etc.
5284 Mon Nov 5 17:29:10 1990 John Gilmore (gnu at cygint)
5286 Handle AMD 29000 a bit better.
5288 * remote-eb.c (readchar): Mask received char log to make it readable.
5289 (remote_start): Pass arguments down to executing program.
5290 Make startaddr unsigned.
5291 infrun.c (start_inferior): Accept args, pass them to
5293 infcmd.c (run_command): Pass args down to start_inferior.
5295 * tconfig/am29k-aout, tconfig/am29k-coff: New files specifying
5296 the target object file format.
5297 tm-29k.h: Pay heed to COFF_ENCAPSULATE.
5299 * am29k-pinsn.c (print_insn): Print 0x on hex numbers in disassembly.
5300 am29k-tdep.c (examine_prologue): Better checking of function prefixes.
5302 Sun Oct 7 18:20:45 1990 John Gilmore (gnu at cygint)
5304 * Makefile.dist (VERSION): Roll version to 3.91.9 and freeze.
5305 * TODO: We did a few things, we have more to do though.
5307 * xm-sparc.h (CLEAR_DEFERRED_STORES): Define.
5308 * inflow.c (inferior_died): Clear deferred stores.
5310 * Debug problems with dummy frames and calls to the inferior.

5313 (sparc_frame_find_saved_regs): Simplify and fix what we find.
5314 (sparc_push_dummy_frame): Simplify and fix what we push.
5315 (sparc_pop_frame): Slightly more hair here, deciding whether
5316 we are restoring a saved PC or returning to a return address in %i7.
5317 * sparc-xdep.c (read_inferior_registers): Debug if valid reg is read.
5319 * utils.c (xmalloc, xrealloc): Return type depends on __STDC__.
5320 * symtab.h (xmalloc): ditto, for obstack_chunk_alloc.
5321 * obstack.h (chunkfun): ditto.
5322 * defs.h (xmalloc, xrealloc): ditto
5324 * utils.c (quit): Grab the terminal from the child if necessary.
5326 * inflow.c (term_status_command): Rename to term_info, change
5329 * sparc-pinsn.c (print_insn): Disassembly prefers real instructions.
5330 (is_delayed_branch): Speed up.
5331 * sparc-opcode.h: Add ALIAS bit to aliases. Fix up opcode tables.
5332 Still missing some float ops, and needs testing.
5334 * Support for input and output radixes other than base 10
5335 * defs.h (input_radix, output_radix): Declare.
5336 * expread.y (yyparse, parse_number): Handle changes of input
5337 radix, and ambiguous names-or-numbers in radixes >10.
5338 * printcmd.c (print_scalar_formatted): Print formatted hex
5339 numbers in varying column widths.
5340 * valprint.c (val_print): Use output_format to print scalar ints.
5341 (set_input_radix, set_output_radix, set_radix): Create.
5342 (set_output_radix): Set output_format from output_radix.
5343 (_initialize_valprint): add `set radix' but leave the others off.
5345 * main.c (execute_command): Let stupid questions be turned off.
5346 (_initialize_main): Handle "set stupidity", etc.
5348 * main.c, inflow.c, inferior.h, frame.h, command.c, defs.h,
5349 sparc-pinsn.c, sparc-xdep.c, value.h, valops.c, values.c: Lint.
5351 Tue Oct 2 11:20:02 1990 John Gilmore (gnu at cygint)
5353 * TODO, Makefile.dist, ChangeLog: Freeze for 3.91.8 release.
5354 bfd stuff is still screwed up, but with some manual work, it
5357 * breakpoint.c (bpstat_do_actions): Start over if a command
5358 proceeds the inferior, since the inferior will have stopped and
5359 will need to have its new stop-actions taken care of.
5361 * dbxread.c (read_struct_type): Expression gives Sun3 4.0.3
5362 compiler fits, simplify it.
5364 * gdb.texinfo (directory command): Doc new dir command.
5365 source.c (directory_command): "dir" now puts things on the front
5366 of the path, moves dups up front, and handles multiple names
5367 on the command line, inserting each one in order. It also
5368 blows away cached line and full_filename info.
5370 * stack.c (backtrace_command): Skip "more stack frames follow"
5373 * Change #ifndef HAVE_VPRINTF to #define MISSING_VPRINTF in
5374 xm-convex.h, xm-hp300bsd.h, xm-isi.h, xm-merlin.h, xm-news.h,
5375 xm-np1.h, xm-pn.h, xm-pyr.h, xm-symmetry.h, xm-umax.h, xm-vax.h.
5376 The only odd one was Gould NP1, which had defined vprintf to
5379 * Merge Ted Goldstein <tedg@Eng.sun.com>'s changes for epoch.
5380 printcmd.c (print_command_1): Pass 'inspect' flag down as a global
5381 variable, inspect_it.
5382 valprint.c (print_string, val_print): Use the global inspect_it
5383 to indicate whether to print in Epoch style or normal style.
5385 Mon Oct 1 23:55:26 1990 John Gilmore (gnu at cygint)
5387 * printcmd.c (call_command): add an alias for the "print" command
5388 which runs expressions and doesn't print the result if void.
5389 (print_command_1): implement it.
5391 * command.c: Remove #if 0'd code. Initialize all the fields
5392 in add_cmd (). Rename do_nothing_command to
5393 not_just_help_class_command, and make it externally visible.
5394 command.h: add user_commands to struct.
5395 * main.c (define_command): Don't overload c->function with a char
5396 string as well as a function pointer.
5398 * eval.c (evaluate_subexp): Reinstall tiemann changes to
5399 calling convention of value_struct_elt () that got dropped in
5402 * tm-sparc.h (FRAME_FIND_SAVED_REGS): move to sparc-xdep.c.
5403 sparc-tdep.c (sparc_frame_find_saved_regs): ditto.
5405 * tm-sparc.h (POP_FRAME): replace some constants with defines.
5407 * sparc-xdep.c (store_inferior_registers): defer stores to regs
5408 until a good time (e.g. when we are about to run the child),
5409 saving ptrace calls.
5410 * infrun.c (proceed): handle DO_DEFERRED_STORES.
5411 * tm-sparc.h: define DO_DEFERRED_STORES.
5413 * sparc-xdep.c (store_inferior_registers): when storing float
5414 registers, don't store stack regs too. When storing the SP,
5415 however, DO store the stack regs too. This fixes a bug in which
5416 the dummy frame is not recognized when a call_function finishes,
5417 because its frame pointer (in the stack regs) was never
5419 (read_inferior_registers): Mark WIM and TBR and FPS and CPS valid
5420 even though we don't know how to read them from an inferior.
5421 valops.c (call_function): Comment about storing SP.
5423 * infrun.c (save_inferior_status): Save away the original bpstat
5424 chain so it can be restored later. Install the copied version for
5425 use by whoever saved the status. It will be blow away by
5426 restore_inferior_status, and the original chain restored. This is
5427 important for people who have pointers into the original.
5429 * breakpoint.c, command.h, copying.awk, dbxread.c, defs.h,
5430 findvar.c, frame.h, obstack.h, obstack.c, inflow.c, value.h,
5431 main.c, printcmd.c, sparc-tdep.c, symtab.c, valprint.c: lint
5434 Fri Sep 28 20:32:46 1990 John Gilmore (gnu at cygnus.com)
5436 * Makefile.dist: Roll version to 3.91.8. Add bfd.h and bfdconfig.h
5437 temporarily to the makefile. Add am29k-opcode.h and WHATS.NEW.
5438 Add stuff.c and kdb-start.c to the OTHERS list for tar files.
5440 Fri Sep 28 19:12:12 1990 John Gilmore (gnu at cygint)
5442 * Merge Mike Tiemann's multiple inheritance changes from Sun.
5443 Store the baseclasses in a type struct starting from array element
5444 0 rather than from the unusual array element 1.
5446 dbxread.c: the above.
5447 (virtual_context): Add
5448 Read new debug information about which virtual function table
5449 a virtual function is from, and store it in fn_field.fcontext.
5451 symtab.h: Add fcontextt. Fix baseclass indices. Typo in
5452 TYPE_FN_FIELD_STATIC_P.
5454 symtab.c: the above.
5455 valops.c: the above. Handle pointer casts of object *'s.
5456 (search_struct_method): Add.
5457 (value_struct_elt): First arg is now a pointer to a value, and is
5460 valprint.c: the above.
5461 values.c (value_virtual_fn_field): Add type arg. Handle
5462 offsetting to the proper object when calling virtual fns.
5464 (baseclass_addr): Add valuep arg.
5466 * README: Document the current state of BFD config (missing).
5467 * TODO, ChangeLog, Makefile.dist: Roll version.
5468 * WHATS.NEW: Add summary of changes since 3.5.
5470 Thu Sep 27 16:23:12 1990 John Gilmore (gnu at cygint)
5472 * dbxread.c (read_struct_type): Clear bit vectors whenever
5474 symtab.c (B_CLRALL): define.
5476 * tm-sparc.h (STORE_RETURN_VALUE): Avoid clobbering types by
5477 using == rather than =. Huh... This fixes the dreaded problem
5478 wherein builtin_type_int becomes TYPE_CODE_FLT.
5480 * core.c (info_files): Show the inferior pid.
5482 * config.gdb: Avoid putting "dir" command into .gdbinit. GDB
5483 already knows how to look in the source directory.
5485 * Remove psymtab hair from many places. Remove duplicated code
5486 for searching symbol tables. Hide psymtabs from most places.
5487 Make it fast to get from a psymtab to its symtab.
5489 blockframe.c (blockvector_for_pc): Remove psymtab hair.
5490 coffread.c (psymtab_to_symtab): Rename to psymtab_to_symtab2.
5491 mipsread.c (psymtab_to_symtab): Rename to psymtab_to_symtab2.
5492 dbxread.c: export psymtab_to_symtab, make it work if called N times.
5493 (psymtab_to_symtab): Rename to psymtab_to_symtab2. Initialize
5494 new symtab completely. New psymtabs get symtab pointer
5495 initialized to zero. Remove MI warning printf.
5496 symtab.h: Comments. Add psymtab to symtab pointer.
5497 (PSYMTAB_TO_SYMTAB): New macro.
5498 symtab.c: use PSYMTAB_TO_SYMTAB. Add psymtab_to_symtab and export it.
5499 source.c: use PSYMTAB_TO_SYMTAB. Remove symtab version and
5501 stack.c (backtrace_command): Avoid pre-pass to read symbols, if
5503 (print_frame_info): Avoid special-casing symbols that have not yet
5506 * source.c (open_source_file): Quick path if we have already
5507 located the source file by its full name.
5509 * symtab.c (lookup_symbol): Use find_pc_symtab rather than
5510 find_pc_psymtab. When a name is found in the misc function
5511 vector, search the symbol table for its mangled name, not the
5512 name that the user typed.
5514 * bfd.h: Fix missing comment terminators, make #endifs match.
5516 * valarith.c (value_less): Handle unsigned int comparisons.
5517 Add FIXME about pointer compares, which assume host and target
5518 pointers are the same.
5520 * command.c (do_nothing_command): lint
5521 dbxread.c: lint. Remove sort_syms. Document C++ visibility info,
5522 fix comments on debug symbol format for visibility. Actually set
5523 visibility of symbols.
5524 main.c (echo_command): lint; use <readline/history.h>.
5525 tm-sparc.h (FRAME_FIND_SAVED_REGS): lint
5526 obstack.h (_obstack_blank): Rearrange pointer math to avoid
5527 pointing past end of allocated memory; saber complains.
5528 obstack.h: Declare the external functions that we use.
5529 valarith.h: use <string.h>
5530 solib.c (solib_add): lint.
5532 Fri Sep 21 17:05:19 1990 John Gilmore (gnu at cygint)
5534 * main.c (initialize_main): Default info_verbose to off, now that
5535 symbol reading is fast.
5536 (quit_command): Avoid clobbering exec_bfd while quitting.
5538 * Initial BFD (binary file diddling library) merger:
5539 coffread.c: Change AOUTHDR to struct exe_hdr.
5541 core.c: initialize initialized data at compile time.
5542 (core_file_command): Move from coredep.c, convert to bfd.
5543 (xfer_core_file): Convert to bfd.
5544 exec.c (exec_file_command): use bfd routines.
5546 mips-tdep.c: Remove exec_file_command and friends.
5549 * coredep.c: (fetch_core_registers) Convert core_file_command to
5550 fetch_core_registers.
5551 mips-xdep.c, sparc-xdep.c, sun3-xdep.c: ditto.
5553 * utils.c: (error): Bogus crap, FIXME, to print bfd errors.
5554 (my_bfd_read): More bogosity, which I don't think we call.
5555 (program_name): Remove this atrocity asap!
5557 Wed Sep 19 13:36:41 1990 John Gilmore (gnu at cygint)
5560 values.c: allocate_repeat_value was not clearing the
5561 optimized_out field.
5562 (value_static_field): minor stylistic fix (wrong macro was used).
5563 valops.c (value_struct_elt_for_address): didn't work for C++
5566 * signame.c (_initialize_signame): Initialize signal names once.
5568 * breakpoint.h, command.c, copying.awk, defs.h, environ.c,
5569 exec.c, frame.h, infcmd.c, inferior.h, main.c, munch, sun3-xdep.c,
5570 symtab.h, tm-29k.h, valprint.c, value.h, values.c: Lint.
5572 * remote-eb.c: Support user-settable baud rates on the serial port.
5574 * tm-sun3.h (PREPARE_TO_STORE): fix typo.
5576 Fri Sep 14 13:28:29 1990 John Gilmore (gnu at cygint)
5578 * tconfig/sun3os4: Remove warning about native assembler,
5579 since it also occurs in the xconfig file.
5581 * findvar.c (registers): Allocate some slop after `registers'
5582 to prevent stray accesses from trashing the next variable.
5584 * tm-68k.h (REGISTER_BYTES): Allocate the right number of bytes
5585 on the sun-3, by changing the #ifdef from `sun3' (which is not
5586 defined by cc) to `sun'. Symptom was trashed builtin_type_XXX
5587 vars, which happened to follow `registers' in the executable.
5589 * readline/history.c (history_search): Heed gcc-2's advice
5590 and parenthesize && inside ||).
5592 * am29k-opcode.h, am29k-pinsn.c, am29k-tdep.c, remote-eb.c,
5593 tm-29k.c: Insert FSF copyright headers.
5595 * remote-eb.c: Better comments.
5597 * Makefile.dist: Update to 3.91.6.
5598 * TODO: note PREPARE_TO_STORE problem.
5600 Thu Sep 13 09:52:33 1990 Jim Kingdon (kingdon at cygint)
5602 * stack.c (frame_info): Only use FRAME_FIND_SAVED_REGS if defined.
5604 * remote.c: Wrap the whole file in #if !defined (SPECIAL_REMOTE).
5606 * infrun.c (wait_for_inferior, at end): Don't set up
5607 prev_* if the inferior no longer exists.
5609 * inferior.h (CALL_DUMMY_LOCATION): New macro, to replace
5610 CANNOT_EXECUTE_STACK.
5611 valops.c (call_function): Use it.
5613 * tm-convex.h: Add CALL_DUMMY_LENGTH for use by PC_IN_CALL_DUMMY.
5615 * inferior.h (PC_IN_CALL_DUMMY): New macro.
5616 infrun.c (wait_for_inferior, 2 places): Use it.
5618 * values.c (value_being_returned): Only use
5619 EXTRACT_STRUCT_VALUE_ADDRESS if defined.
5621 * Move PREPARE_TO_STORE from xm-sun3.h to tm-sun3.h to do the
5622 right thing for remote-eb.c.
5624 * sun3-xdep.c: Remove extraneous call to remote_store_registers.
5625 * sun386-xdep.c, hp300hpux-xdep.c, sparc-xdep.c: Ditto.
5627 * blockframe.c: Put get_frame_saved_regs inside #if !defined
5628 (FRAME_FIND_SAVED_REGS).
5630 * findvar.c ({fetch,store}_registers): Check for
5631 REMOTE_{FETCH_STORE}_REGISTER macro.
5633 * findvar.c (get_saved_register): Add argument lval and
5634 change meaning of argument addr.
5635 findvar.c: Change calls to get_saved_register to reflect
5636 new calling convention.
5637 valops.c (value_assign): Use get_saved_register instead of
5638 find_saved_register.
5640 Sun Sep 2 12:40:20 1990 Jim Kingdon (kingdon at cygint.cygnus.com)
5642 * coffread.c (read_one_sym): Make temp_aux an AUXENT, not
5643 an (uninitialized) pointer to one. Use "&" when passing it
5646 Fri Aug 31 22:57:54 1990 Jim Kingdon (kingdon at cygint.cygnus.com)
5648 * coffread.c (getfilename): Use DGUX x_offset and x_name if
5651 * coffread.c (symbol_file_command): Put semicolon after
5653 Put safe_to_init_tdesc_context in #if defined (TDESC).
5654 Put #ifdef TDESCs in 1st column for non-ANSI cpp's.
5655 coffread.c: #include <sys/stat.h>.
5656 (read_coff_symtab): Typo: in_source_files -> in_source_file.
5657 Add missing ')' in check for "lc%" and friends. Remove
5659 Declare read_one_sym() at top of file.
5660 (read_file_hdr): Put in extra #ifdefs so MC68MAGIC and
5661 MC68WRMAGIC can have the same value without causing a duplicate
5664 Thu Sep 13 15:55:36 1990 John Gilmore (gnu at cygint)
5666 * Allow a Makefile to be built without building the
5667 tm and xm file links that screw up builds in subdirectories.
5668 This is done with `config.gdb none', then you can do things
5669 like `make gdb.tar.Z'.
5670 * tconfig/none: Config file for no target system
5671 * xconfig/none: Config file for no host system
5672 * config.gdb: If no TM or XM files are called out by the
5673 host or target file, don't make links for them.
5675 * cplus-dem.c: Add documentation.
5677 * dbxread.c (read_ofile_symtab): Turn a fatal error into a
5678 simple error, so the user's gdb doesn't crash due to some object
5679 file problem (e.g. somebody is rebuilding the file out from under
5682 * printcmd.c (print_address_symbolic): demangle the symbol.
5684 * Makefile.dist (OTHERS): Remove tdesc-lib because it has
5685 Motorola copyrights in it. Make "make gdb.tar.Z" work.
5686 (alldeps.mak): sort and uniq all results from this; duplicates
5687 hose gdb.tar.Z link building. Remove RCS files from
5688 tconfig and xconfig. Add config files for sun386. Add
5689 a few odd files to OTHERS and HFILES.
5691 Mon Sep 10 21:20:24 1990 John Gilmore (gnu at cygint)
5693 * Makefile.dist: Pull solib.c to tconfig/sun?os4.
5694 Roll version number to 3.91.5. Make lint work in bindir.
5696 * README: Document cross-debugging and new file structure.
5698 * blockframe.c: Lint. Include "value.h" to declare read_register.
5699 (find_pc_partial_function): remove duplicate line.
5701 * command.h: Lint. Declare error_no_arg and dont_repeat.
5703 * tm-news.h: Remove inadvertently duplicated stuff.
5705 * mipsread.c: Remove cache_pc_function stuff, now done cleanly.
5706 Clean up usage of misc_function_type. Declare some CORE_ADDRs.
5708 * config.gdb: Allow `config.gdb host target' form. Clean
5709 up previous change that printed bogus messages when you just said
5712 * core.c: #include "command.h" for lint.
5715 * main.c: Remove some casts of enums. Lint.
5722 * printcmd.c (initialize_printcmd): Fix thinko in inspect cmd.
5724 * sparc-tdep.c (isannulled): Take instruction as parameter, don't
5725 read it from memory. This will allow us to save ptrace calls
5726 eventually. Changed caller single_step too.
5728 * sparc-xdep.c (fetch_inferior_registers): Avoid reading regs
5729 that we aren't going to use, saving many ptrace calls, especially
5730 when watchpointing or single stepping. Use some #define's for
5732 (store_inferior_registers): Ditto.
5733 (core_file_command): Use some #define's for constants.
5735 * tm-sparc.h: Add #define's for some register numbers, so we
5736 can eliminate the use of random constants in sparc-xdep.c.
5738 * stack.c (frame_command, print_frame_info, up_command,
5739 down_command) Remove frame_changed, since it
5740 causes a bug and doesn't seem to do anything useful. In some
5741 places it was used as a flag, in others as a stack level (?).
5743 * utils.c: Use MISSING_VPRINTF rather than HAVE_VPRINTF, so the
5744 default is to use the portable (vprintf) version rather than the
5746 * xm-news.h (MISSING_VPRINTF): Add.
5748 * valprint.c (val_print): Demangle fancy vtbl printouts. Lint.
5750 Sat Sep 8 00:24:12 1990 John Gilmore (gnu at cygint)
5752 * Remove stuff that forces -Bstatic linking of gdb, and warnings
5753 about linking debugged programs -Bstatic in the sun?os4 config
5754 files in tconfig and xconfig subdirectories.
5756 * main.c (main): Remove unreached exit(0) now that we exit
5759 * Create TODO file for online bug list. There are too many
5760 "little" bugs to keep track of on paper.
5762 * Change Projects file to refer to bug-gdb@cygnus.com
5763 rather than kingdon@ai.
5765 Fri Sep 7 23:35:15 1990 John Gilmore (gnu at cygint)
5767 * Makefile.dist (VERSION): 3.91.4 now.
5769 * symtab.c (init_misc_bunches): Rename from init_misc_functions.
5770 (condense_misc_bunches): Add sanity check that misc_count is
5771 the same as the number of symbols in the bunch.
5773 * coffread.c: rename init_misc_bunches. Pass an argument
5774 to condense_misc_bunches (a zero).
5776 * dbxread.c (partial_symbol_file_read): Call init_misc_bunches
5777 every time we are called; don't rely on our caller to do it.
5778 (add_file): Remove call to init_misc_bunches.
5780 * mipsread.c: Only warn, don't error, if unknown symbol types.
5781 This keeps an old gdb from falling on its face if it sees newly
5782 extended symbol info. Rename init_misc_bunches.
5784 Fri Sep 7 22:58:15 1990 John Gilmore (gnu at cygint)
5786 * Merge in changes from Per Bothner for DECstations and other
5787 MIPS stuff. The rest is Bothner speaking:
5789 The next message is a merger of Alessando Forin's mips port with
5790 mine. I've tried to use my good if biased judgment to get
5791 the best of both. It *does* need testing.
5793 Some of the changes are general, *not* mips-specific.
5796 Didn't believe in little-endian bit order.
5797 There are still inconsistencies about whether flags
5798 like BITS_BIG_ENDIAN are integer (#if ...) or
5799 boolean (#ifdef ...). I tried to paper over them.
5801 dbxread.c,coffread.c,mipsread.c,symtab.c,symtab.h:
5802 Moved some misc_function code that was common to
5803 {dbx,coff,mips}read.c to symtab.c.
5804 In the process, I think I cleaned things up a bit.
5805 At the same time, moved obsavestring and obconcat to symtab.c.
5808 Removed obsolete condense_addl_misc_bunches (use
5809 condense_misc_bunches(1) instead).
5812 Needed to include <sys/dir>, at least on DECstations.
5814 valops.c, mips-tdep.c, tm-mips.h:
5815 Added PUSH_ARGUMENTS macro to support funny argument-pushing
5816 conventions (when STACK_ALIGN is insufficient).
5817 Needed on mips, where doubles need 8-byte alignment,
5818 but ints only need 4.
5821 Removed cruft that was not being used.
5822 Merged in many fixes (most from Frank Yellin, fy@lucid.com).
5825 Print $ before register-names (I think that makes things a little
5827 Never print two instructions, even if one delays.
5828 Removed hex-disassemble set_cmd. (This is not mips-specific,
5829 so I think the argument is whether it is generally worthwhile or not.
5830 I'm inclined to think not, given how easy it is to
5831 convert between radixes in gdb.)
5834 This is basically Alessando's code.
5835 It doesn't use obstacks; I changed it to use obstacks
5836 in a few minor places where using malloc causes a
5837 memory leak. (Probably, more places could/should be changed.)
5838 I added record_misc_function where it was missing.
5839 In symbol_file_command and add_file_command, I tried
5840 to make the code consistent with more recent versions.
5841 Minor sylistic changes in parse_procedure.
5842 Make a .gdbinfo. psuedo-symbol point back to the real
5843 procedure symbol (using the isym field).
5846 This is basically from my port, but with a lot of details
5847 and a number of routines merged in from Alessando's version.
5848 I basically used my code "raw" backtrace (use heuristics
5849 from the actual code, rather than symbol table info) - though
5850 the idea is Alessandro's. I feel my code is a little cleaner
5851 here, particularly in being a little more flexible, such as being
5852 able to handle gcc-produced code (which it now can).
5853 It also doesn't do frame caching (which is not useful
5854 more recent gdb versions).
5855 I also used my code for push_/pop_dummy, more or less.
5856 I tried to incorporate AF's code for testing sigtramp
5857 while backtracing; I probably got it wrong.
5858 Added mips_print_register, which tries to scrunch as much
5859 information as possible on a screen...
5860 Removed the skip-prologue set_cmd. As with hex-disassemble (see
5861 under mips-pinsn.c), I don't see anything mips-specific here,
5862 and I don't see it being all that useful anyway.
5865 Added a $fp psuedo-reg distinct from $fp (nice for gcc).
5866 Use more register names (rather than hard-cases numbers).
5868 Thu Sep 6 18:33:15 1990 John Gilmore (gnu at cygint)
5870 * Hack up 3.90.11 changes:
5872 * Makefile.dist (depend): parameterize $(GCC).
5873 Add solib.c and solib.o.
5874 (readline): Fix vpath for both absolute or relative SRCDIR.
5876 * blockframe.c: Fix from Schaefer@asc.slb.com for shared libs.
5877 Also, let the part I didn't understand at least compile so
5878 I can test the rest. FIXME.
5880 * dbxread.c: Fix thinko using strcmp.
5881 (init_psymbol_list): declare static.
5882 (partial_symbol_file_open): Comment cleanups better, avoid
5883 cleaning up the string table since the caller will do that.
5884 Move the stat for mod time into symbol_file_command, temporarily.
5885 (There should be a mod time for each symbol file, eventually,
5886 to control its rereading. FIXME.)
5888 * infptrace.c (PT_WRITE_D): use same value as PT_WRITE_I for
5889 SunOS, which gives error for shared libs otherwise. (From
5890 Schaefer, probably FIXME needs work for portability.)
5892 * solib.c: Move #include "param.h" to work.
5893 Lowercase all the Uppercase Letters In the Messages.
5894 (find_solib): Clean up inferior_so_name for debug printouts.
5895 Allow no argument, to mean all shared libraries.
5897 * symmisc.c: include param.h to get CLEAR_SOLIB.
5899 Wed Sep 5 18:00:08 1990 John Gilmore (gnu at cygint)
5901 * Merge in Kingdon's changes from FSF: the diffs from 3.90.9
5902 to 3.90.11. ChangeLog entries below are from this.
5904 Wed Jun 13 09:17:39 1990 Jim Kingdon (kingdon at mole.ai.mit.edu)

5910 Tue Jun 12 16:15:26 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5914 * Makefile.dist (gdb.tar.Z): Change linking of config so it works.
5916 Thu Jun 7 16:22:27 EDT 1990 Jay Fenlason (hack@ai.mit.edu)
5918 * sparc-opcode.h Added single-operand version of rett.
5920 Mon Jun 4 18:12:31 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5922 * m-sparc.h (REG_STRUCT_HAS_ADDR, STRUCT_ARG_SYM_GARBAGE):
5923 Put parens around gcc_p in expansion.
5925 Thu May 24 15:44:51 1990 Jim Kingdon (kingdon at mole.ai.mit.edu)
5927 * utils.c (lines_to_list): Return 10 if lines_per_page == 0.
5929 Wed May 23 16:36:04 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5931 * Changes for Sun shared libraries:
5932 blockframe.c (find_pc_partial_function): If a non-text symbol
5933 is found, set *address = pc - FUNCTION_START_OFFSET.
5934 breakpoint.c (insert_breakpoints) [DISABLE_UNSETTABLE_BREAK]:
5935 Disable breakpoints instead of giving an error.
5936 source.c (select_source_symtab): Initialize cs_pst.
5937 symmisc.c: Call CLEAR_SOLIB if defined.
5938 symtab.h: Make text{low,high} CORE_ADDR not int.
5939 (psymtab): New field addr.
5941 dbxread.c: Move DECLARE_FILE_HEADERS outside functions.
5942 (record_misc_function): Give correct type for N_DATA symbols.
5943 (condense_misc_bunches): do "misc_function_count = j" regardless
5945 Take code which is shared between symbol_file_command and
5946 add_file_command and put it into partial_symbol_file_{open,read}.
5947 Split add_file_command into add_file_command and add_file.
5948 Make psymtab_to_symtab read in the string table if the file
5950 Two new parameters to read_dbx_symtab and start_psymtab.
5951 tm-sunos.h: New file.
5953 Tue May 22 17:43:03 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5955 * infcmd.c: Change cont_command to continue_command and "cont"
5958 Mon May 21 14:41:41 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5960 * breakpoint.c (enable_breakpoint): Get value of watchpoint.
5962 * defs.h [sparc]: Use <alloca.h> regardless of __GNUC__.
5964 * values.c (USE_STRUCT_CONVENTION): Check for structures of
5965 size 1,2,4,8 rather than size < 8.
5967 * dbxread.c (dbx_lookup_type): Do f->length *= 2 as many times
5968 as necessary, not just once.
5970 * sparc-opcode.h: Add a bunch of new opcodes which Sun as supports.
5972 Thu May 17 15:04:09 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5974 * {t,x}m-sun386.h, sun386-xdep.c, {x,t}config/sun386
5976 * tm-news.h: Add CALL_DUMMY_*.
5978 * tm-68k.h: Remove duplicate comment at FRAME_FIND_SAVED_REGS.
5980 * config.gdb: In list_host, list_target, use ${i}, not $i.
5982 Tue May 15 21:27:12 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5984 * source.c (find_source_lines) [BROKEN_LARGE_ALLOCA]: Use xmalloc.
5986 * sparc-opcode.h: Change all store floating-point state register
5987 instructions to have the right match & lose fields.
5989 Sat May 5 12:39:18 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5991 * Makefile.dist: Move -I${srcdir} to GLOBAL_CFLAGS and pass
5993 config.gdb: If srcdir != ., create readline directory and
5994 copy a makefile into it.
5996 * wait.h, infrun.c: Change WRETCODE to WEXITSTATUS for
5997 consistency with POSIX.
5999 * breakpoint.c (bpstat_stop_status): Disable watchpoint
6000 when we exit its exp_valid_block.
6002 Tue Sep 4 11:46:46 1990 John Gilmore (gnu at cygint)
6004 * Makefile.dist: Bump version to 3.91.3.
6006 * Clean up handling of breakpoint commands (somewhat).
6007 Prompted by Tiemann bug report "cont 10" doesn't work any more.
6009 inferior.h: Add breakpoint_proceeded to inferior status struct
6010 and globals; save it and restore it.
6011 (clear_breakpoint_commands): Cleanup, remove old #define.
6013 infrun.c (clear_proceed_status): Set breakpoint_proceeded.
6014 (save_inferior_status, restore_inferior_status): handle it also.
6015 (proceed): Remove earlier code that set breakpoint_proceeded.
6016 It is now set only in clear_proceed_status.
6017 (clear_proceed_status): Cleanup, use bpstat_clear rather
6018 than clear_breakpoint_commands. No callers need the stop_bpstat
6019 between clear_proceed_status and proceed.
6021 infcmd.c: Add breakpoint_proceeded definition and comment.
6022 (cont_command, jump_command, signal_command): Move call to
6023 clear_proceed_status right next to call to proceed.
6025 breakpoint.c (bpstat_do_actions): Avoid clobbering our
6026 caller's argument while running down the chain of breakpoints.
6027 Use new variable "breakpoint_proceeded" to determine when
6028 a command that it executes moves the inferior past the
6030 (bpstat_clear): Handle NULL argument.
6031 (bpstat_clear_actions): Avoid useless call to
6032 breakpoint_auto_delete.
6033 (delete_breakpoint): Clean up bpstat's that are pointing to
6034 the deleted breakpoint from the stop_bpstat chain.
6035 (breakpoint_auto_delete): Simplify.
6037 * Clean up handling of EOF, error on stdin, etc. This was
6038 prompted by a network problem that caused gdb to go into an
6039 infinite loop filling up its malloc'd memory.
6041 main.c (return_to_top_level): Cleanup: call bpstat_clear_actions,
6042 not clear_breakpoints_commands, which is now gone.
6043 (main): If command_loop returns (e.g. from EOF on stdin), do
6044 a quit_command (looping back to command_loop if quit_command
6045 doesn't really quit).
6046 (command_loop): check result from command_line_input and
6047 exit if it returns NULL, rather than passing the NULL to
6049 (gdb_readline): Free malloc'd result space before returning
6052 * utils.c (query): Handle C-d to mean "yes", just as if the
6053 input was not a terminal. Also avoid infinite loop if EOF
6054 occurs in mid-input-line before newline. This allows
6055 query to be used at EOF on stdin with reasonable results.
6057 * infrun.c (proceed): Set breakpoint_proceeded.
6059 * values.c (value_as_long): Avoid infinite recursion for enums.
6060 (_initialize_values): Fix typo in help msg (kingdon).
6062 * Makefile.dist (RL_LIB): Use RL_LIB_DEP for dependencies,
6063 RL_LIB for linking. This allows -lreadline for linking
6064 and nothing for dependencies, once readline is a real library.
6066 * config.gdb: Jim Kingdon: give useful error message if the
6067 host or target type is not recognized.
6069 * defs.h (alloca): SPARC <alloca.h> does not declare alloca,
6070 it just defines it. Dumb, but deal with it.
6072 * Jim Kingdon suggests:
6073 in xconfig/sun3os4, CFLAGS should be XM_CFLAGS.
6075 Wed Aug 29 18:03:27 1990 John Gilmore (gnu at cygint)
6077 * Makefile.dist (VERSION): Bump version # to 3.91.2.
6079 * Clean up Bothner's changes.
6081 * blockframe.c (clear_pc_function_cache): New function.
6082 * blockframe.c: remake cache_pc_function_* static.
6083 * dbxread.c (symbol_file_command): remove references to
6084 cache_pc_function_* variables.
6085 * dbxread.c (read_struct_type): Use VOFFSET_STATIC.
6086 * printcmd.c: Avoid kludging a global variable (addressprint)
6087 to avoid printing the address of a string twice. Instead,
6088 pass the format letter 's' down low enough that it can be seen
6089 to avoid this problem.
6090 (print_formatted): Pass format arg to value_print.
6091 (restore_addressprint): Remove function.
6092 (do_examine): Avoid hacking addressprint, cleanups and such.
6093 (print_frame_args): Add a comment to a Bothner change.
6094 * symtab.h: define VOFFSET_STATIC and use it instead of "-1".
6095 * symmisc.c (free_all_symtabs): Call clear_pc_function_cache
6096 to wipe out the values cached in blockframe.c.
6097 * symtab.c (find_method): Add comment saying how big you must
6098 allocate to be "big enough". Per being terse again.
6099 * valprint.c (val_print): Handle format letter "s" to print
6100 strings without addresses. Add comment to vtbl printing code
6101 which casts with wild abandon. Rearrange reference-printing
6103 @0xaddr: value (print w/addressprint)
6104 value (print w/~addressprint)
6105 @0xaddr (parameter lists w/addressprint)
6106 or nothing (parameter lists w/o addressprint)
6108 Tue Aug 28 10:47:18 1990 John Gilmore (gnu at cygint)
6110 * Merge more changes from Per Bothner:
6112 Gdb's handling of TYPE_CODE_REF was so counter-C++ (and otherwise
6113 annoying) that I tried to improve it. Here are my suggestions.
6115 These patches all attempt to handle TYPE_CODE_REF (as in C++) better.
6118 Do automatic de-reference when taking the address of a reference.
6120 Don't deref_ref when printing parameter lists.
6122 More attempts at treating refernences properly.
6124 In val_print, if deref_ref==0, don't print dangling " = ".
6126 Add COERCE_REF macro, which de-references an REF.
6128 * Merge changes from Per Bothner:
6130 * Fixed (Sony news)-specific configuration problems.
6131 * Fixed other problems with using vanilla pcc and libc (enum problems;
6132 assumption that vsprintf exists).
6133 * Some major speed-ups (finc_pc_partial_function now caches a match;
6134 parsing avoids duplicate symbol_lookup calls).
6135 * Changed handling of baseclasses (no longer use baseclasses field
6136 of struct type, use the first n_baseclasses fields instead).
6137 * Various minor changes/fixes, most C++-related.
6140 Cache the most previous match from find_pc_partial_function.
6141 (Save both low and high ends of matching function's pc range.)
6142 This speeds up the loop of infrun.c:wait_for_inferior quite
6143 a bit, and makes step/next commands much zippier.
6145 Added an enum->int cast (otherwise, some compilers barf).
6147 No longer set baseclass offset to 0, since multiple
6148 inheritance now mostly works.
6149 Added a number of casts, to shut up compiler warnings
6150 (after stabs where made enums, not ints).
6151 When discarding a symbol table (in symbol_file_command),
6152 must clear the cache introduced in blockframe.c.
6153 Don't convert $vtbl_ptr_type to vtbl any more.
6154 Get rid of TYPE_BASECLASEES and baseclass_vec (see also symtab.h).
6155 Mask off sign bit emitted by g++ for virtual table offset.
6156 Set voffset to -1 (not 1) for static member functions.
6158 Changed parsing/lexing of names to avoid doing symbol lookup twice
6159 (once when lexing to determine symbol class, once for real).
6160 Now only call symbol_lookup once. Fields of 'this' win especially big.
6162 Subpress printing addr twice in the case of 'x/s addr'.
6164 lookup_basetype_type is no longer used.
6165 Add find_methods as recursive helper function to decode_line_1.
6166 This allows multiple inheritance to work.
6167 Also, once one or more matches has been found, do not look in
6168 base-classes. (Baseclass methods would be overridden, anyway.)
6170 Removed baseclasses array in struct type.
6171 Instead of using baseclasses[i], use fields[i-1].
6172 Added virtual_field_bits[i] to indicate if the i'th baseclass is virtual.
6173 Changed sign convention of voffset (previous was inconsistent).
6175 Some macros (CALL_DUMMY and relatives) were missing. Put them back.
6177 Used to assume existence of vsprintf. Re-written to not need it
6178 if HAVE_VPRINTF is undefined.
6180 typecmp was too pessimistic. Made it less so.
6182 Don't print space after address.
6183 If vtable points to a misc symbol (with 0 offset), print it,
6184 since that indicates the actual class of the object.
6185 Changed ype_print_derivation_info to use new inheritance
6186 scheme (without baseclasses vector).
6188 In value_primitive_field, fixed some bugs left over from previous set of fixes.
6189 Also, changes needed because TYPE_BASECLASSES were removed.
6191 REGISTER_U_ADDR didn't work for PC. Rewrote to use an array.
6193 Tue Aug 21 20:08:54 1990 John Gilmore (gnu at cygint)
6196 If there is no path set, and the symbols don't indicate what directory
6197 a file was compiled in, look in the current directory. But either
6198 a path or a known compilation directory will prevent this.
6201 Three independent bug fixes:
6202 * Remove the #if 0 block that breaks some stuff.
6203 * SunOS 4.1 fixed the promoted-parameter-wrong-addr bug in Sun C;
6204 adapt gdb to either SunOS 4.0.* or 4.1.
6205 * MAX_OF_TYPE and MIN_OF_TYPE thinko. By tedg@sun, I think.
6208 Instantiate the class T when looking for methods in it. (Tiemann@sun)
6211 (type_print) Demangle the name being printed.
6212 (type_print_base) Handle botched demangling without coredump (tiemann).
6215 (check_stub_method): Document routine.
6216 (tiemann) fix bug for no-arg functions
6217 Avoid clobbering beyond end of malloc'd storage.
6218 Terminate the argument list properly.
6220 Sat Aug 18 01:29:59 1990 Per Bothner (bothner@cs.wisc.edu)
6222 * Changes merged by John Gilmore:
6225 In breakpoint_1, use new print_address_symbolic instead
6226 of find_pc_partial_function. (This forces use of assembler-level
6227 addresses, and avoids misleading non-mangled source-level names.)
6229 Generalize ansi argument such that -1 means skip arglist totally.
6230 Removed global variable print_ansi_qualifiers (which made
6231 code non-reentrant), in favor of extra explicit arguments
6232 to internal routines.
6234 Add new helper function print_address_symbolic.
6235 Use find_pc_misc_function instead of find_pc_partial_function
6236 (since we want assembler-level symbols here).
6238 Print unknown function as just "f (...)", not "f (...) (...)".
6239 Use new fputs_demangled explicitly.
6241 Fixed a typing violation (problem: value.h cannot be imported
6242 without renaming many variable in this file).
6243 lookup_symbol: If no matching misc_func, look for a C++-mangled name.
6244 decode_line_1: Moved forward some never-reached code.
6245 Made decode_line_2 skip function prologues correctly.
6247 fputs_filtered should not demangle by default.
6248 Add new fputs_demangled to demangle on demand..
6250 Change value_struct_elt to use value_primitive_field (using recursive
6251 utility function search_struct_field). This allows foo.bar to work
6252 for multiple inheritance (so far only for data fields).
6253 Change check_field in the same way (recursive helper function
6254 to support multiple inheritance).
6255 (Note: there are more of these problems that I haven't fixed.
6256 Any code that says TYPE_BASECLASS (t, 1) is probably wrong.)
6257 value_of_this: 'this' symbol name is now just "this", note "$this".
6259 Don't print static members.
6260 Avoid printing "members of <type>" if there are none.
6261 Simplified type_print_derivation_info by merging duplicate code.
6262 Remove useless blank lines in type_print_base (ptype command).
6264 Added declaration of new routine value_primitive_field.
6266 Added value_primitive_field which is generalized version of
6267 value_field that can handle multiple inheritance (non-zero offsets etc).
6268 Re-implemented value_field to call value_primitive_field.
6270 Fri Aug 17 23:33:44 1990 John Gilmore (gnu at cygint)
6272 * infcmd.c -- insert else to avoid 'delete env' coredump when you
6273 delete the whole environment. Karl Berry reported the bug.
6274 * source.c - fix openp to avoid //'s in filenames, which
6275 trigger an Emacs bug causing it to not be able to find files
6276 when running gdb in a window.
6277 * dbxread.c - zap the #if 0 that botches the add-file code.
6278 It seems to work a lot better without all the code commented out.
6280 Fri Jul 20 16:58:46 1990 John Gilmore (gnu at cygnus.com)
6282 * Merge Tiemann's and Ted Goldstein's changes, detailed below,
6285 Tue Jul 17 19:34:33 1990 Ted Goldstein (tedg at golem)
6287 * Makefile - added a ${CFLAGS} to a couple of entries,
6288 added remote-sa.sparc.c
6289 * added remote.sa-sparc.c, a modification of remote.c
6290 which conducts a dialog directly with the SparcStation prom.
6291 * breakpoint.c, infrun.c, sparcdep.c added
6292 remote_insert_breakpoint(), and remote_remove_breakpoint()
6293 to breakpoint.c instead of directly writing breakpoint instructions.
6294 * sparcdep.c on remote_debugging,there is no need
6295 to remove signle step breakpoint instructions.
6296 * main.c added "-epoch" flag and "int epoch_interface" to main.c
6298 * printcmd.c - epoch interface sends lisp expressions to open up
6299 epoch windows on inspection.
6300 * valprint.c - added arrayprint, and addressprint and made adding
6301 format controls easier
6302 * wait.h added a couple of undef's because we were getting
6303 complaints about WSTOPSIG and WTERMSIG begin redefined.
6306 Wed Jul 4 05:27:51 1990 Michael Tiemann (tiemann at masham)
6308 * symtab.c (decode_line_1): Add support for handling method stubs
6309 in the type information.
6311 Tue Jul 3 09:39:18 1990 Michael Tiemann (tiemann at masham)
6313 * values.c (baseclass_addr): Run loop from INDEX+1 to
6314 N_BASECLASSES; otherwise, we can still get into a loop.
6315 @@ This should be restructured to use a cleaner search strategy.
6317 Sun Jul 1 12:28:51 1990 Michael Tiemann (tiemann at masham)
6319 * dbxread.c (define_symbol,read_type): Grok GNU C++'s new
6320 abbreviation "Tt" for tags which have the same name as their
6323 Fri Jun 29 01:03:46 1990 Michael Tiemann (tiemann at masham)
6325 * symtab.c (list_symbols): add ability to set breakpoints on all
6326 the functions which match a particular regular expression.
6328 Tue Jun 26 04:26:29 1990 Michael Tiemann (tiemann at masham)
6330 * cplus-dem.c (cplus_demangle): New parameter ANSI says whether we
6331 should print ANSI qualifiers (such as `const' and `volatile').
6332 All callers changed to call with ANSI == 1, except from
6333 `check_method_stub', which uses old-style syntax.
6335 * symseg.h (struct fn_field): Remove unneccessary `args' field.
6336 * symtab.h (TYPE_FN_FIELD_ARGS): Redefined.
6338 * values.c (check_stub_method): New function.
6340 * cplus-dem.c (do_type): Handle "long long" (encoded as 'x').
6342 * dbxread.c (read_type): Handle new GNU C++ method type stubs.
6343 * valprint (type_print_base): Ditto.
6345 * symtab.c (gdb_mangle_typename): New function.
6347 Tue Jun 5 00:18:43 1990 Michael Tiemann (tiemann at gzilla)
6349 * breakpoint.c (catch_command): New function. Provides a
6350 mechanism to set breakpoints based on catch clauses.
6351 (disable_catch): Similar, but disables breakpoints on catch
6353 (delete_catch): Similar, but deleted breakpoints on catch clauses.
6355 Sun Jun 3 22:54:08 1990 Michael Tiemann (tiemann at gzilla)
6357 * blockframe.c (blockvector_for_pc): New function.
6358 * blockframe.c (block_for_pc): Changed to call
6359 `blockvector_for_pc' and get the block itself.
6361 * stack.c (catch_info): New function. Prints info about
6362 exceptions which can be caught in the current frame.
6363 * stack.c (print_frame_label_vars): New function. Similar to
6364 `print_frame_local_vars'.
6365 * stack.c (print_block_frame_labels): Prints out labels that are
6366 defined in this frame. These labels are exceptions that can be
6369 * dbxread.c: Updated to handle N_CATCH symtab types.
6371 Thu May 3 22:10:00 1990 Michael Tiemann (tiemann at teacake)
6373 * valprint.c (everywhere): TYPE_NAME (TYPE) no longer comes in the
6374 form "struct ..." for GNU C++. Don't flush any part of TYPE_NAME
6375 when printing the type.
6377 Wed May 2 22:43:04 1990 Michael Tiemann (tiemann at teacake)
6379 * valprint.c (val_print): Use `baseclass_addr' to access the
6380 baseclasses pointed to via the derived class object at VALADDR.
6382 * values.c (baseclass_addr): New function. Casts derived pointers
6383 to baseclass pointers taking virtual baseclasses and multiple
6384 inheritance into account.
6386 Sat May 5 12:39:18 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
6390 Fri May 4 12:12:55 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
6392 * breakpoint.c (watch_command, bpstat_stop_status): Deal with
6393 exp_valid_block field correctly.
6395 * infrun.c (wait_for_inferior): When checking "don't even think
6396 about breakpoints" if stop_signal == SIGTRAP && trap_expected,
6397 also check step_resume_breakpoint.
6398 Insert breakpoints and continue (not step) if
6399 step_resume_break_address != NULL, even if another_trap.
6400 If trap_expected and we enter sigtramp, then set up a
6402 If trap_expected is set when we hit the step_resume_break,
6404 When calling resume and trap_expected says tell resume to step
