1 Fri Nov 22 08:27:40 1991 John Gilmore (gnu at cygnus.com)
3 * infptrace.c, language.h: Lint.
4 * m2-exp.y: #undef MAX and MIN in case system includes set them.
5 * xm-tahoe.h: Set HOST_BYTE_ORDER. Include system versions of
6 {BIG,LITTLE}_ENDIAN and the INT_MAX family first, to avoid
8 * defs.h: Reorder things so that the xm-file gets first crack
9 at #define's, followed by defs.h and then the tm-file.
10 * Makefile.in: Remove spaces after 'ignore exit code' - flags.
11 Late-model BSD 'make's don't cope with them.
13 Thu Nov 21 23:48:56 1991 John Gilmore (gnu at cygnus.com)
15 * Makefile.in: Roll new files into various lists.
17 Thu Nov 21 18:26:11 1991 Fred Fish (fnf at cygnus.com)
19 * dwarfread.c (struct_type): Must initialize the c++ specific
20 portion of union types as well as struct types, since gdb attempts
21 to reference the c++ specific info for both types.
23 Thu Nov 21 10:23:52 1991 John Gilmore (gnu at cygnus.com)
25 * Makefile.in: Roll VERSION to 4.2.90.
27 * defs.h: Incorporate param.h into defs.h. All users changed.
28 * param-no-tm.h: Change users to define TM_FILE_OVERRIDE instead.
29 * param.h, param-no-tm.h: Removed.
30 * Update copyrights in all changed files.
31 * dbxread.c, dwarfread.c, inflow.c, infrun.c, m2-exp.y, putenv.c,
32 solib.c, symtab.h, tm-umax.h, valprint.c: Lint.
33 * tm-convex.h, tm-hp300hpux.h, tm-merlin.h, tm-sparc.h,
34 xm-merlin.h: Avoid host include files in target descriptions.
35 * getpagesize.h: Removed, libiberty copes now.
36 * Makefile.in: Remove getpagesize.h, param.h, param-no-tm.h.
38 * exec.c (exec_files_info): If `verbose' is set, show file offset
41 * main.c: Use getcwd rather than getwd.
42 * standalone.c: Fake getcwd rather than getwd.
43 * xm-*.h: Remove fake values of MAXPATHLEN.
45 * xcoffexec.c: Add /* */ to #if 0'd thing to help ANSI.
47 Wed Nov 20 18:35:56 1991 John Gilmore (gnu at cygnus.com)
49 * Remove gdb/hp-include. Support for HP a.out oddities should be
50 in BFD, not in GDB. Move gdb/hp-include/a.out.h to include/a.out.hp.h.
52 * infptrace.c, tm-sun386.h: Cashier <a.out.gnu.h>, remove refs.
54 * configure.in, xconfig, tconfig, Makefile.in, doc/gdbint.texinfo:
55 Makefile fragments for various hosts and targets now come from
56 gdb/config/mh-* and gdb/config/mt-*. This is for consistency with
59 * rs6000-pinsn.c, rs6k-opcode.h: Clean up.
60 * rs6k-opcode.def: Delete.
62 Wed Nov 20 05:04:40 1991 Fred Fish (fnf at cygnus.com)
64 * dwarfread.c: Recognize obsolete form of AT_element_list
65 attribute still used by at least one AT&T compiler, and possibly
68 Tue Nov 19 07:53:55 1991 Fred Fish (fnf at cygnus.com)
70 * dwarfread.c (enum_type, struct_type): Ignore names invented by
71 helpful compilers for anonymous structs, unions, and enums.
73 * c-exp.y, m2-exp.y: Add defines for yymaxdepth, yy_yys, and
74 yy_yyv, so multiple parsers produced by SVR4 versions of yacc
75 can coexist in the same executable without collision.
77 * symtab.h: Add declaration for lookup_template_type() to kill
78 compiler warnings about conversions from int to pointer.
80 Mon Nov 18 17:45:18 1991 Fred Fish (fnf at cygnus.com)
82 * procfs.c: Move inclusion of defs.h to before param.h, as in
83 all the other source files that include both. This is required
84 to supply some typedefs that are used in files included by param.h.
86 * m68k-tdep.c (m68k_skip_prologue): Add generic m68k support for
87 skipping function prologues, ala the other cpu families (i386,
88 mips, m88k, etc). Add the ability to skip movm and fmovm
89 instructions in the prologues. Still needs support for profile
90 (-p compiled) prologue sequences (FIXME).
92 * tm-68k.h: Change SKIP_PROLOGUE macro to use the new generic
93 m68k prologue skipping function by default.
95 * tm-altos.h, tm-isi.h: Continue to use the old definition of
98 Mon Nov 18 15:12:45 1991 John Gilmore (gnu at cygnus.com)
100 * Makefile.in: Remove tdesc stuff, and extra blanks before colons.
101 * blockframe.c: Remove tdesc-related code. Default
103 * infrun.c: Remove tdesc-related code.
104 * m88k-tdep.c (frame_chain_combine, init_frame_pc): Remove copies
105 of defaultable things.
106 * tm-m88k.h: New file, common to all Moto 88k target configs.
107 Derived from tm-delta88.h.
108 * tm-delta88.h: Use it.
109 * xm-m88k.h: Common file for 88K hosts. Remove obsolete stuff.
110 * xm-delta88.h: Use it.
111 * tm-*.h: Remove FRAME_CHAIN_COMBINE macros, since all are
113 * coffread.c: Remove tdesc stuff.
114 * tconfig/delta88, tconfig/m88k: Remove tdesc stuff.
115 * xconfig/m88k: Rename tm-88k.h to tm-m88k.h.
117 Mon Nov 18 13:51:37 1991 Per Bothner (bothner at cygnus.com)
119 * source.c (open_source_file): If openp fails, try again
120 using just the base (non-directory) part of the filename.
121 This solves various annoying problems, such as when the
122 source was compiled with an absolute pathname - and the
123 source files have moved. Or if the source was compiled
124 using a relative pathname, it can be more convenient
125 to just specific the source directory to the dir command.
127 Mon Nov 18 00:04:41 1991 Fred Fish (fnf at cygnus.com)
129 * cplus-dem.c (munge_function_name): Add missing third arg to
130 instance of call to do_type().
132 * dwarfread.c: Changes to match new dwarf.h. Remove
133 AT_deriv_list, AT_loclist, AT_incomplete, AT_const_data,
136 Sun Nov 17 16:20:53 1991 Michael Tiemann (tiemann at rtl.cygnus.com)
138 * symtab.h (struct type): Moved C++-specific fields into new type
139 `struct cplus_struct_type'. Now takes 10% less memory. Many
141 * symtab.c (init_type): Don't set fields belonging to
142 TYPE_CPLUS_SPECIFIC unless TYPE is TYPE_CODE_STRUCT.
143 * buildsym.c (read_type): Allocate TYPE_CPLUS_SPECIFIC for
145 (read_struct_type): Ditto. Also, add comments about how we can
146 deduce TYPE_VPTR_FIELDNO from inheritance info and fieldname info.
147 * coffread.c (decode_base_type): Allocate TYPE_CPLUS_SPECIFIC for
149 (read_struct_type): Ditto.
150 * dwarfread.c (struct_type): Ditto.
152 * symtab.c (read_range_type): Don't set TYPE_MAIN_VARIANT.
153 (lookup_pointer_type): Don't use or set TYPE_MAIN_VARIANT.
154 (lookup_reference_type): Ditto.
156 * cplus-dem.c: Many changes made to handle decoding of

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

203 Motorola 88000 port without tears, I mean without tdescs.
205 * m88k-tdep.c: Blow away all tdesc stuff.
206 Provide functions for all the frame-related macros in
207 tm-delta88.h. Adopt i960-style EXTRA_FRAME_INFO.
208 (examine_prologue, frame_find_saved_regs, skip_prologue): borrow
209 from i960-tdep.c and adapt to the function prologues on the 88k.
210 (read_next_frame_reg): Borrow from mips-tdep.c.
211 FIXME: frame_locals_address should go away.
213 * tm-delta88.h: Dump all the tdesc stuff.
214 Macros for all frame-related stuff call fns of same name.
215 Remove duplicated definitions. FP_REGNUM becomes same as
218 * xm-88k.h: Eliminate lots of library dependencies, now handled
219 in libiberty. Eliminate KDB nonsupport.
221 * doc/gdbint.texinfo: Add rudiments on frames. FIXME, add more.
224 * stack.c (frame_info): Mark frameless functions.
225 Print locals address (FIXME, remove if same).
226 * blockframe.c: Comment changes, FIXME after.
227 * coffread.c: Even without TDESC, need to zap "@" symbols.
228 Don't register for wierd format names; change the names in BFD.
230 * alloca.c, language.c, tdesc.c: Lint.
231 * tdesc.c, tdesc-lib: FIXME: remove these.
233 Tue Nov 12 19:30:22 1991 John Gilmore (gnu at cygnus.com)
235 * Makefile.in: Add tdesc library support. Fixups to lint,
238 Tue Nov 12 13:43:26 1991 Per Bothner (bothner at cygnus.com)
240 * symtab.c (decode_line_1): Remove spurious call to operator_chars.
242 Allow setting breakpoints on C++ destructors.
243 * valops.c (destructor_name_p): Don't check TYPE_HAS_DESTRUCTOR,
244 since it lies. Rely on callers to catch missing destructors.
245 * symtab.c (decode_line_1): For example (see above), here.
246 * buildsym.c, symtab.h: Remove TYPE_FLAGS_HAS{CON,DE}STRUCTOR
247 flags since they are no longer used.
249 Fixes to support C++ methods with functional parameters.
250 * c-exp.y (func_mod rule): Allow (and ignore) list of parameter
251 types in a function type.
252 * eval.c (parse_and_eval_type), value.h: New function,
253 parse_and_eval_type, is based on old code from check_stub_method.
254 But don't actually evaluate the cast, since that calls
255 value_cast(), whcih may fail. Just extract the type
256 from the parsed expression.
257 * values.c (check_stub_method): While looping through the
258 arguments, adjust depth *after* parameter has been handled.
259 Replace call and setup of parse_and_eval with new function
262 Tue Nov 12 09:40:07 1991 Fred Fish (fnf at cygnus.com)
264 * utils.c, rem-multi.shar: Remove fixed arg count version of
267 * altos-xdep.c, arm-xdep.c, coffread.c, command.c, convex-xdep.c,
268 core.c, dwarfread.c, gould-xdep.c, infcmd.c, language.c,
269 m88k-xdep.c, main.c, printcmd.c, pyr-xdep.c, source.c,
270 sun386-xdep.c, symm-xdep.c, umax-xdep.c, values.c, xcoffread.c:
271 Change all instances of use of fixed args concat() to variable
272 args concat() now located in libiberty.
274 Tue Nov 12 07:23:46 1991 John Gilmore (gnu at cygnus.com)
276 * Makefile.in: Add xcoffread.c, xcoffexec.c.
277 * xcoffread.c: New file for handling AIX mangled-coff files.
278 * xconfig/rs6000, tconfig/rs6000: New files.
279 * buildsym.c: Add hooks for xcoffread.c.
280 * rs6000-pinsn.c, rs6000-tdep.c, rs6000-xdep.c, tm-rs6000.h,
281 xm-rs6000.h, rs6k-opcode.def, rs6k-opcode.h: New files.
282 * xcoffexec.c: New file for handling AIX shared libraries.
284 Mon Nov 11 19:14:31 1991 Fred Fish (fnf at cygnus.com)
286 * core.c: Minor rewording of message to user containing name of
287 (and possibly arguments to) the program that generated a core
290 * elfread.c: Remove the register_addr() stub now that it is no
293 * procfs.c: Move misplaced #endif for ATTACH_DETACH. Add new
294 fetch_core_registers() function for core file support.

298 * dwarfread.c (dwarf_psymtab_to_symtab): Remove leftover call
299 to do_cleanups() which resulted from a previous change.
301 * elfread.c: Re-enable compilation of register_addr() stub
302 whenever it is not supplied by coredep.c
304 Sat Nov 9 00:40:32 1991 John Gilmore (gnu at cygnus.com)
306 Add tracking of object files (that contain symbols) to gdb.
307 This includes a "struct objfile" that owns symtabs and psymtabs
308 that were read in from that binary file.
310 * symfile.h: Add struct objfile. Add pointer to the objfile
311 into the struct sym_fns.
312 Replace global `symfile' and `symfile_mtime' with
313 `symfile_objfile'. Add global object_files chain.
315 * symfile.c: Move param.h above symtab.h.
316 (sort_misc_function_vector): Add.
317 (syms_from_objfile): Was syms_from_bfd.
318 (symfile_open): Now returns objfile.
319 (allocate_objfile): New.
320 (free_objfile): New, replacing free_all_.*symtabs.
321 (symfile_init): Takes objfile arg, puts it in sym_fns result.

327 * dbxread.c: Make more errors into complaints.
328 (push_subfile, pop_subfile): Move to buildsym.c.
329 (dbx_symfile_read, dbx_symfile_init, fill_symbuf, read_dbx_symtab,
330 start_psymtab, psymtab_to_symtab_1, read_ofile_symtab,
331 dbx_psymtab_to_symtab, ): Use bfd ops, don't use file descriptor.
332 Pass objfile. Change callers.
333 (fill_symbuf, SWAP_SYMBOL): Take bfd as arg.
334 (read_dbx_symtab): Just wipe out new symbols, not all, on error.
335 (end_psymtab): Blow away psymtab if empty.

337 (process_one_symbol): Use push_context and pop_context.
338 (virtual_context): Delete #if 0'd obsolete stuff.
340 * buildsym.c (end_symtab): Pass objfile.
341 (dbx_lookup_type): Handle null typevector.
342 (dbx_alloc_type): Check file number, not sym number, for -1.
343 (find_symbol_in_list): Add for xcoffread.
344 (start_symtab): Default typevector is empty. Keep reusing same
346 (end_symtab): Take objfile argument and pass it to
347 allocate_symtab. Don't make a symtab if no blocks or symbols.
348 Handle empty typevector.

361 * dwarfread.c (scan_compilation_units, start_psymtab,
362 process_dies, end_symtab, dwarf_build_psymtabs,
363 read_lexical_block_scope, read_func_scope, read_file_scope): Take
364 and use objfile argument.
365 (psymtab_to_symtab_1, read_ofile_symtab): Don't take or use file
366 descriptor. Use BFD internal functions instead.
367 (end_symtab): Call global allocate_symtab.
369 * elfread.c, target.c: Minor changes to accommodate objfiles.
370 * symtab.h: partial_symbol_table has no symfile_name member now.
371 (fn_fieldlists voffset): avoid non-int bitfield.
372 (struct symtab): Add objfile * and objfile_chain * of symtabs.
373 (struct partial_symtab): Add objfile * and objfile_chain * of
374 psymtabs. Remove symfile_name.
376 * symmisc.c: Lose free_all_symtabs, free_all_psymtabs.
377 (printsyms_command): Rename from print_symtabs. Add selective
378 listing if 2nd argument given. Print objfile info.
379 (printpsyms_command): Rename from print_partial_symtabs. Ditto all.
380 (printobjfiles_command): New; prints objfiles lists, and checks
381 for consistency of symtab, psymtab, and objfile lists.
383 * symfile.h, symfile.c, symtab.h: Lint
385 Fri Nov 8 23:38:48 1991 John Gilmore (gnu at cygnus.com)
387 * command.c: Include param.h.
388 * defs.h (warning_setup, warning): Declare.

394 Thu Nov 7 18:26:15 1991 Steve Chamberlain (sac at rtl.cygnus.com)
396 * Makefile.in: link with libiberty after libreadline, since
397 readline might want something in libiberty.
398 * m88k-xdep.c: Fixed the register offsets in the ptrace_user
399 struct for BCS 88k machines.
400 * xm-m88k.h: don't define USIZE if already defined.
401 * configure.in: Added delta88 target.
403 Thu Nov 7 04:51:19 1991 John Gilmore (gnu at cygnus.com)
405 * am29k-pinsn.c, am29k-opcode.h: Fix decoding of mtacc, dmac, fmac.
407 * tm-*.h: Remove READ_DBX_FORMAT, COFF_FORMAT, and
408 READ_MIPS_FORMAT, which have been unused since BFD. Still
409 remaining is COFF_NO_LONG_FILE_NAMES.
410 * tm-sun3.h, tm-altos.h: Remove detritus accidentally left from
411 function calling code moved to m68k-tdep.c.
413 Wed Nov 6 17:21:59 1991 John Gilmore (gnu at cygnus.com)
415 * coffread.c: Eliminate c_nsyms in favor of c_naux.
416 Complain if no auxents on .bf and .ef FCN symbols, and assume
417 lots of line numbers.
418 (init_linenos, enter_linenos): Use a sentinel at the end of the
419 read-in linenos, to make for a fast, safe loop-end test.
421 Wed Nov 6 02:54:08 1991 Steve Chamberlain (sac at cygnus.com)
423 * coffread.c (read_coff_symtab): coffread used to rely on the
424 x_sym.x_misc.x_lnsz.x_lnno field giving the # of linnos in a
425 function. Two of the formats I'm using (29k and 88k) don't seem to
426 set it. Ths patch to fcn_last_line and (enter_linenos) is an
427 attempt to use the actual size of the linno table in the file to set
428 the number of linenos to process.
430 Tue Nov 5 22:47:46 1991 Steve Chamberlain (sac at cygnus.com)
432 * Makefile.in: put a - infront of the mv y.tab.c c-exp.tab.c and
433 mv y.tab.c m2-exp.tab.c, so that if bison is used, and the files
434 are created in place, so the mv fails, then the make continues.
436 Tue Nov 5 16:47:47 1991 Per Bothner (bothner at cygnus.com)
438 Add C++ as a separate language.
439 * defs.h (enum language): Add language_cplus.
440 * dwarfread.c (end_symtab): Support language_cplus.
441 * c-exp.y: Add new struct language_defn cplus_language_defn.
442 Don't set c to be the default language (see main.c).
443 * c-exp.y (yylex): Only look for field of this if
444 language is C++. (First difference from C!)
445 * language.c: Add case branches for C++ (currently, all
446 the same as C). Also, add c++ to "usage" note for "set lang".
447 * valprint.c (typedef_print). Add case branches for C++.
448 * main.c (main): New way to set initial language: Look at
449 file extension of psymtab containing main(). (Same as we
450 do for symtabs, but avoid loading the symtab yet.)
451 * symtab.c: New routine find_main_psymtab(), used by main()
452 to set initial language.
453 * symfile.c (allocate_symtab): Move code for mapping file
454 extensions-> languages to new deduce_language_from_filename().
456 Fix a C++ problem when looking for methods in super-classes.
457 There was confusion between base and derived types.
458 * valops.c (value_fn_field): Change function interface.
459 * values.c: Use new value_fn_field interface.
461 Mon Nov 4 10:49:33 1991 Per Bothner (bothner at cygnus.com)
463 * infrun.c: Fixed typo in comment.
464 * utils.c: All the v*fprintf emulation is now in libiberty,
465 so we can get rid of some junk.
466 * xm-sun3os4.h, xm-sun4os4.h, xconfig/decstation, xconfig/i386sco,
467 xconfig/sun3os4, xconfig/sun4os4: Don`t need HAVE_STRSTR any more.
468 * m68k-pinsn.c (print_insn_arg): Support BB/BW/BL
469 type operands, as used by branch instructions.
470 * gmalloc.c: Fix prototype of memcpy.
471 * elfread.c: Comment out register_addr, since it conflicts
472 with the one in coredep.c.
473 * buildsym.h: Remove extern declarations of two functions
474 that are really static in buildsym.c.
475 * tm-mips.h: Add symbolic names for more registers.
476 * mips-xdep.c (store_inferior_registers): Use new register names.
477 * xm-mips.h: Simplify REGISTER_U_ADDR, since it is now
478 only used for core files, not ptrace. Therefore,
479 the KERNEL_U_ADDR hack is no longer needed.
480 The mapping to ptrace number is now in in mips-xdep.c.
481 * mips-xdep.c: Define REGISTER_PTRACE_ADDR (using the
482 mapping from the old REGISTER_U_ADDR), and use it
483 in {fetch,store}_inferior_registers.
484 * mipsread.c: Rename #include ecoff.h to new name coff-mips.h.
485 * mips-tdep.c (mips_push_dummy_frame, mips_pop_frame):
486 Save/restore FP regs correctly (?).
487 * dbxread.c: Remove duplicate define_symbol and type_synonym_name
488 (these had been previously moved to buildsym.c).
489 Hence, define_symbol becomes extern instead of static.
490 * buildsym.c (read_struct_type): Comment out bogus handling
491 of C++ operator methods. Minor hacking of reading of class
492 contexts. Make define_symbol non-static, so dbxread.c can call it.
494 Fri Nov 1 11:05:47 1991 John Gilmore (gnu at cygnus.com)
496 * mipsread.c (read_mips_symtab, read_the_mips_symtab): Use real
497 filename with error messages.
498 * stack.c (frame_select_command): Rename to select_frame_command
499 to avoid "fr" and "fra" having nonunique completions.
500 * symfile.c (sort_symtab_syms): Ignore sort of zero symtab *.
501 (symfile_init): Print file format name when unable to handle it.
502 (free_named_symtabs): Use BLOCKVECTOR rather than obsolete BLOCKLIST.
503 * symmisc.c (free_symtab): Only free linetable if nonzero.
504 * symtab.h: Remove obsolete BLOCKLIST macros.
506 Thu Oct 31 18:12:43 1991 Stu Grossman (grossman at cygnus.com)
508 * infrun.c (wait_for_inferior): another stepi/nexti fix. Ensure
509 that stop_step is 1 at bottom of main loop. I don't know why this
510 needs to be done, but it helps me sleep better at night.
512 Sun Oct 27 18:18:39 1991 Stu Grossman (grossman at cygnus.com)
514 * main.c (initialize_history): Read history after reading all
517 Sun Oct 27 14:09:25 1991 John Gilmore (gnu at cygnus.com)
519 * buildsym.c: Break out initial malloc sizes.
520 (record_line): Record directly in a subfile. Alloc on demand.
521 (compare_line_numbers): Add from xcoffread.c.
522 (end_symtab): New params say whether to sort pendings and
523 linetable. Patch block stabs if defined. Shrink linetable before
524 allocating the symtab.
525 * buildsym.h: Delete line_vector* and prev_line_number. Add
526 global_stabs and file_stabs for xcoffread.
527 * dbxread.c (start_subfile): Move to buildsym. Change above calls.
528 * symtab.h: LINETABLE(symtab) can now be null. Zap LINELIST.
529 * symmisc.c, symtab.c: Cope with null LINETABLEs.
531 * blockframe.c: Pass fromleaf to INIT_EXTRA_FRAME_INFO.
532 * tm-29k.h, tm-88k.h, tm-i960.h, tm-irix3.h, tm-mips.h, tm-pyr.h,
533 tm-sparc.h: Accept fromleaf parameter.
534 * c-exp.y (yyerror): Pass error message if given.
535 * configure.in: Add rs6000 host and target.
536 * inflow.c (new_tty): O_NOCTTY kludge for RS/6000.
537 * symfile.h (entry_point): Add.
539 Sat Oct 26 00:16:32 1991 John Gilmore (gnu at cygus.com)
541 * buildsym.c: New file. Breaks out symbol-table-building routines
542 from dbxread.c, so they can be shared with xcoffread.c.
543 * buildsym.h: New file. Declarations for buildsym.c users.
544 * dbxread.c: Remove large chunks into buildsym.c.
545 * Makefile.in: Add buildsym.c and buildsym.h.
547 * symfile.c (syms_from_bfd): New routine.
548 (add_symbol_file): Call it to do the real work.
549 (syms_from_bfd): Initialize entry_point before calling symfile_init.
550 * symtab.h, symfile.c, coffread.c, mipsread.c, dwarfread.c:
551 Avoid declaring or setting entry_point (symfile.h & symfile.c cope).
553 Fri Oct 25 10:58:16 1991 Mark Eichin (eichin at cygnus.com)
555 * cplus-dem.c (cplus-demangle): added support for templates, static
556 data, and the new (correct) mangling for destructors.
558 * dwarfread.c: (dwarfwarn): created a varargs version of
559 dwarfwarn, for non __STDC__ compilers.
561 * c-exp.y: (yylex): added match for "template" token.
562 (typebase): added TEMPLATE name '<' type '>' clause, for explicit
563 specification of template types.
565 * symtab.c: (lookup_template_type): new function for finding
566 templates in symbol table.
567 (type_name_no_tag): changed to explicitly check for s/u/e at the
568 beginning of the symbol - if it is a template, none of these will
569 be there (but the name will still contain spaces.)
571 Fri Oct 25 18:59:32 1991 Per Bothner (bothner at cygnus.com)
573 Various fixes to improve g++ debugging.
574 * symtab.h: Add is_const and is_volatile flags for each method.
575 These are bit fields - take their space from voffset,
576 which shrinks to 30 bits. Since voffset is now a bitfield,
577 make it unsigned for portability. This changes its interpretation
578 slightly: Static methods now have voffset 1 instead of -1,
579 and virtual offsets start at 2, not 1.
580 * symtab.c: Renamed gdb_mangle_typename to gdb_mangle_name,
581 since it now returns an entire magled method name, not just
582 the type part. This avoids some duplication.
583 It also allows us to correctly mangle const and volatile
584 methods (using the new is_const and is_volatile bit fields
586 * valprint.c (type_print_base), values.c (check_stub_method):
587 Simplify by using new gdb_mangle_name.
588 * values.c (value_headof): Fix to correctly handle single
589 inheritance (actually two fixes, either of which suffices).
590 * dbxread.c (read_struct_type): Handle const and volatile
592 * dbxread.c (read_struct_type): Yet one more place where
593 we must handle '\\' continuations.
594 * valprint.c (vtbl_ptr_name): Add final '\0'.
596 Fri Oct 25 16:06:38 1991 Stu Grossman (grossman at cygnus.com)
598 * tm-sparc.h, tm-68k.h (EXTRACT_RETURN_VALUE): fix output of
599 short return values for sparc and 68k. Patch from Paul Eggert.
601 * coffread.c, coredep.c, i386-xdep.c: install patches for
602 SysV/386 3.2 from Mauro DePalma.
604 Fri Oct 25 02:02:13 1991 John Gilmore (gnu at cygnus.com)
606 * core.c (core_file_info), exec.c (exec_file_info): Print file
607 type. Use printf_filtered.
609 * valops.c (value_fetch_lazy): Avoid 0-length fetches.
611 Thu Oct 24 23:06:40 1991 Fred Fish (fnf at cygnus.com)
613 * dwarfread.c: Add casts to remove compiler warnings.
615 * tm-3b1.h, tm-68k.h, tm-altos.h, tm-amix.h, tm-hp300bsd.h,
616 tm-hp300hpux.h, tm-isi.h, tm-news.h, tm-pn.h, tm-sun2.h,
617 tm-sun3.h: Remove locally duplicated code for calling functions
618 in the inferior. The only differences were in the specific trap
619 vectors used and whether or not an fpu was present. These are
620 now handled by appropriate definitions of BPT_VECTOR and
621 HAVE_68881 respectively. Other minor obvious cleanups.
623 * valops.c: Correct a minor misspelling.
625 * utils.c: Remove local BSD/USG hacks that are now in libiberty.
627 * dwarfread.c: Remove prototype for dwarfwarn. Does not work
630 Thu Oct 24 09:33:44 1991 John Gilmore (gnu at cygnus.com)
632 * stack.c (frame_command): Always print. Use new
633 frame_select_command to select a frame without printing.
635 * dwarfread.c: Use <varargs.h>, since <stdarg.h> is not portable.
637 Thu Oct 24 01:32:51 1991 Fred Fish (fnf at cygnus.com)
639 * dwarfread.c: New file for DWARF debugging format support.
641 * elfread.c: New file for ELF object file format support.
643 * procfs.c: New file for SVR4 /proc (process file system) support.
645 * tm-amix.h, xm-amix.h, tconfig/amix, xconfig/amix: New files for
648 * xm-svr4.h, tm-svr4.h: New files for SVR4 support.
650 * xm-m68k.h: New file for host machines with m68k cpu.
652 * Makefile.in: Add elfread.c and dwarfread.c to SFILES_MAINDIR.
653 Add elfread.o and dwarfread.o to OBS.
655 * symfile.h: Add "elf" to list of supported formats in comment.
657 * c-exp.y, defs.h, symtab.h, valprint.c: Add three new builtin
658 types to gdb, builtin_type_long_double, builtin_type_complex, and
659 builtin_type_double_complex. Add and use new TARGET_SHORT_BIT,
660 TARGET_INT_BIT, TARGET_LONG_BIT, TARGET_FLOAT_BIT,
661 TARGET_DOUBLE_BIT, TARGET_LONG_DOUBLE_BIT, TARGET_COMPLEX_BIT, and
662 TARGET_DOUBLE_COMPLEX_BIT, as the sizes in bits of the indicated
663 types on the target machine (ala the existing TARGET_LONG_LONG_BIT).
665 * infrun.c: When using SVR4 /proc interface instead of ptrace(),
666 call proc_set_exec_trap() to setup child to stop at first instruction.
668 * inftarg.c: When using SVR4 /proc interface, call proc_wait()
671 * m68k-tdep.c: Add new routines supply_gregset(), fill_gregset(),
672 supply_fpregset(), and fill_fpregset(), which are machine
673 dependent support routines for SVR4 /proc interface.
675 * utils.c: Add warning_setup() and warning(). Warning() behaves
676 the same as error() except that it returns normally rather than
677 jumping back to command level. Modules that don't want to call
678 warning() for some reason, but want to produce their own warnings,
679 can call warning_setup() to ensure compatibility with the way
680 warning() and error() deal with the terminal.
682 * symtab.c: Make internal errors produce more useful messages.
684 * tm-68k.h: Move code that is duplicated in almost every single
685 m68k based machine's configuration files to this common file.
686 Duplications in the configuration files still need to be removed
689 * infrun.c (child_create_inferior): System V versions must call
690 setpgrp() with no arguments, to comply with prototyping typically
693 * munch: Add support for SVR4 style nm output.
695 * dbxread.c, mipsread.c symmisc.c, symtab.c: Remove the object
696 file specific fields from the partial symbol table structure and
697 replace them with a pointer to private data for each different
698 flavor of object file reader to initialize appropriately.
700 Wed Oct 23 09:38:20 1991 John Gilmore (gnu at cygnus.com)
702 * xconfig/sun[34]os4: Add note about strstr botch on sunos4.0.3c
705 * mipsread.c (fixup_undef_type): New function. If a struct /
706 union / enum is defined in a header file but nowhere else used,
707 (by typedefing, pointer referencing or declaration) the mipsread code
708 builds the complete tree for the structure but leaves its code as
709 TYPE_CODE_UNDEF as it doesn't know what kind of aggregate it is.
710 Guess its type based on the details of the members.
712 Tue Oct 22 18:04:32 1991 Stu Grossman (grossman at cygnus.com)
714 * infrun.c (wait_for_inferior): Check return value from
717 Mon Oct 21 17:47:03 1991 Stu Grossman (grossman at cygnus.com)
719 * infrun.c (wait_for_inferior): fix stepi/nexti that was broken
720 by my last edit to this routine.
722 Mon Oct 21 14:27:43 1991 John Gilmore (gnu at cygnus.com)
724 * tm-sun3.h (FIX_CALL_DUMMY): problem with cross debugging.
725 FIX_CALL_DUMMY does unaligned accesses and/or forgets to byte swap
726 the values before putting them into the dummy code. (From Peter
729 Mon Oct 21 10:04:39 1991 Steve Chamberlain (steve at rtl.cygnus.com)
731 * configure.in: added ebmon target.
733 Wed Oct 16 22:49:58 1991 John Gilmore (gnu at cygnus.com)
737 * Makefile.in: Roll VERSION to 4.2.
738 * README, TODO, WHATS.NEW: Update.
740 * core.c (core_open): Improve error message for bad file.
741 Pass .reg virtual memory address to fetch_core_registers to help
742 it find the registers in the core-file header.
743 * coredep.c (fetch_core_registers): Take new argument, use it,
744 and pass it to register_addr to locate the block of registers.
745 * xm-mips.h: Update KERNEL_U_ADDR for new scheme. Cleanup a bit.
747 * dbxread.c (read_dbx_symtab, process_one_symbol): Handle
748 Sequent N_FN_SEQ like everybody else's N_FN.
750 * main.c: Circumvent SCO cc bug with #if !!defined(USG).
751 * tm-i386v.h: #endif guck.
752 * xconfig/i386*: Remove -Dgetpagesize()=4096 kludge.
753 * xconfig/i386sco: Add HAVE_STRSTR to avoid ANSI bdeath.
754 * xconfig/tahoe: Add REGEX, which seems to be missing.
756 * coredep.c: Add <sys/types.h> for SCOnix.
757 * dbxread.c (read_dbx_symntab): Avoid coredump on malformed file.
758 * printcmd.c (print_formatted): Flush output before disassembly.
760 Tue Oct 15 20:12:32 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
762 * doc/refcard.tex (sec "Working Files"): consistent metavars and
763 other improvements, due to comments by François Pinard
764 (pinard@iro.umontreal.ca)
766 * doc/gdb.texinfo (appendix "Installing GDB"): changes in
767 configure, and improvenets related to Pinard's refcard comments
769 Tue Oct 15 08:45:12 1991 John Gilmore (gnu at cygnus.com)
771 Changes from Fred Fish:
772 * tm-68k.h (FPI_REGNUM): Add.
773 * infrun.c (child_create_inferior): flush stdout and stderr
775 * configure.in: Handle amigados, amix hosts and targets.
776 * inflow.c: Handle TIOCGLTC_BROKEN for Amiga.
779 * values.c (show_convenience): Use printf_filtered.
780 * main.c (define_command): Check result of lookup_command for
782 (echo_command): Use printf_filtered, and force output out.
784 * dbxread.c (read_enum_type): Avoid Modula-2 kludge that breaks C
786 * i387-tdep.c (double_to_i387): Fix typo for double_to_ieee_extended.
787 * utils.c (_initialize_utils): If !ISATTY, don't paginate.
788 * configure.in, tconfig/decstation, xconfig/decstation: Rename
789 dec3100 to decstation.
791 Mon Oct 14 13:37:50 1991 Roland H. Pesch (pesch at cygnus.com)
793 * doc/gdb.texinfo: Catch up to changes recorded here in ChangeLog
794 (nodes Continuing and Stepping; Memory; Targets) clarifications
797 Fri Oct 11 23:27:06 1991 John Gilmore (gnu at cygnus.com)
799 * tm-{irix3,mips,nindy960,pn,symmetry,vx960}.h: Move
800 REGISTER_U_ADDR to corresponding xm- file. Sugg. by Peter Schauer.
802 * symmisc.c (print_partial_symtabs): Add printpsyms debug cmd.
804 * m68k-tdep.c (m68k_push_dummy_frame, m68k_pop_frame): Add
805 generic routines for calling inferior functions.
807 * blockframe.c (inside_main_scope, inside_entry_scope): New.
809 * copying.awk: Filter formfeeds out of copying & warrantee.
810 Make them available as `show copying' and `show warrantee' also.
811 * main.c (print_gnu_advertisement): Advt `show' commands.
813 Thu Oct 10 17:25:47 1991 John Gilmore (gnu at cygnus.com)
815 * mach386-xdep.c: Even when cross-compiling, leave in the
816 core-file reading code.
817 * core.c (get_core_registers): Avoid coredump if no .reg section.
819 Wed Oct 9 17:03:34 1991 John Gilmore (gnu at cygnus.com)
821 * mipsread.c, coffread.c: initialise TYPE_VPTR_FIELDNO to -1.
822 This avoids coredumps under `set print object on' in value_headof
823 (called erroneously by value_from_vtable_info) for `p &struct'
824 or `p *struct'. From Peter Schauer.
826 Mon Oct 7 00:06:52 1991 John Gilmore (gnu at cygnus.com)
828 * Makefile.in: Roll version to 4.1.2.
829 * dbxread.c: Use aout64.h, not a.out.gnu.h. Get external symbol entry
830 size from BFD (but, FIXME, we don't yet read external nlists's and
831 convert them to internal nlists's before handling them -- we still
832 assume they have the same size and alignment.) Use SET_NAMESTRING
834 * exec.c (exec_file_command): Move dead coff-encapsulation code
836 * m88k-tdep.c, m88k-xdep.c: Remove encap test and #inc <a.out.h>.
838 Fri Oct 4 22:30:06 1991 John Gilmore (gnu at cygnus.com)
840 * configure.in, tm-i386v.h, xm-i386v.h: Intel 386 Mach host port.
841 * xm-i386mach.h, mach386-xdep.c, xconfig/i386mach: New files.
843 Fri Oct 4 17:04:31 1991 Per Bothner (bothner at cygnus.com)
845 More patches from Peter Schauer <pes@regent.e-technik.tu-muenchen.de>:
846 * mips-xdep.c (store_inferior_registers): Don't try to
847 write the (pseudo) FP.
848 * mipsread.c (parse_partial_symbols): Improved algorithm for
849 setting pst->texthigh.
851 Fri Oct 4 16:47:32 1991 Roland H. Pesch (pesch at cygnus.com)
853 * doc/Makefile: make TEXINPUTS include . everywhere
855 Fri Oct 4 00:35:56 1991 John Gilmore (gnu at cygnus.com)
857 * coffread.c, dbxread.c, symfile.c, symmisc.c, symtab.h: Remove
858 vestiges of typevectors, which were for symsegs and are no longer
859 used. (From a question by Eliot Dresselhaus
860 <dresselh@RFT30.nas.nasa.gov>).
862 Thu Oct 3 09:33:26 1991 John Gilmore (gnu at cygnus.com)
864 * dbxread.c, coffread.c: static-ize functions that were
865 gratuitiously external. (From Fred Fish.)
867 * c-exp.y: sym->class to SYMBOL_CLASS (sym).
869 * dbxread.c (dbx_lookup_type): Keep doubling size of typevector
870 until it is large enough.
872 * dbxread.c (read_type): Handle error case slightly better.
873 Make complaint message not C++-specific.
875 Wed Oct 2 17:21:07 1991 Stu Grossman (grossman at cygnus.com)
877 * infrun.c (wait_for_inferior): Fix step/next so that you only
878 stop at the beginning of a new line. This fixes various problems
879 with for loops, nested if-else's and switch statements.
881 Tue Oct 1 06:33:55 1991 John Gilmore (gnu at cygnus.com)
883 * symtab.c (lookup_symtab_1, lookup_symbol): "fatal" errors
884 between symtabs and psymtabs become ordinary error()s.
886 * dbxread.c (read_dbx_symtab): Relocate end_of_text_addr
887 properly, making "end pc" correct in shared lib psymtabs.
888 (From Guy Harris <guy@auspex.com>.)
890 Mon Sep 30 13:15:31 1991 John Gilmore (gnu at cygnus.com)
892 * dbxread.c: Enable, but soften, const_vol_complaint.
893 (read_dbx_symtab): N_STSYM and N_LCSYM define static vars.
894 Ditto Gould N_NBSTS and N_NBLCS. Also, all types in the psymtab
895 should be file-scope, not global.
896 (read_struct_type): Remove ancient multiple-inheritance warning.
897 (read_range_type): Check base type, complain & patch if undefined.
898 * stack.c (frame_info): Demangle the function name in `info stack'.
901 Sat Sep 28 10:02:33 1991 John Gilmore (gnu at cygnus.com)
903 * eval.c (evaluate_subexp_for_address): Don't use
904 TYPE_POINTER_TYPE directly (it might be zero if this type has
905 never had a pointer created before); use lookup_pointer_type.
906 * symtab.c (lookup_method_type): Arguments were swapped in all
907 callers, so fix it here. I'm amazed this worked at all!
909 Fri Sep 27 18:09:31 1991 John Gilmore (gnu at cygnus.com)
911 * c-exp.y, m2-exp.y: Define more yysymbols that happen to be
912 "bss" rather than "data" symbols, but which still conflict.
915 * coffread.c (coff_symfile_read): Use xmalloc, not malloc.
916 * core.c (core_files_info): Shorten output.
917 * exec.c (exec_files_info): Ditto.
918 (build_section_table): Ignore zero-length sections.
919 * language.c, printcmd.c: Lint.
920 * language.h (get_frame_language): Declare.
921 * saber.suppress: update.
922 * stack.c (find_relative_frame): Remove complex code that was
923 #if 0'd, stick with simple code. Lint.
924 * saber.suppress: Update a bit.
925 * symfile.c (add_symbol_file_command): Add "?" to question.
926 * utils.c (parse_escape): Avoid \a due to bdead compilers.
927 * value.h: Declare typedef_print.
929 * valprint.c (val_print, type_print_base): TYPE_CODE_RANGE less
932 * nindy-tdep.c (nindy_frame_chain_valid): Use lookup_misc_func.
933 (Reported by Mark Peek <mark@imagen.com>.)
935 * solib.c (solib_map_sections): Relocate all sections, even
936 though only the text section's size is tracked. Mark ld_text
937 for eventual elimination as we generalize to N sections.
939 * infrun.c (wait_for_inferior): Don't check if the PC is in a
940 call_dummy if we were stopped by a random signal that is being
941 passed to the program. This produced wierd results when calling
942 functions in the inferior and signals (e.g. SIGALRM) were in use.
944 Tue Sep 24 18:05:30 1991 John Gilmore (gnu at cygnus.com)
946 * infrun.c (IN_SIGTRAMP): Not parenthesized properly.
947 Bugfix from Paul Eggert <eggert@twinsun.com>.
948 * tm-ultra3.h (IN_SIGTRAMP): Ditto.
949 * valprint.c (print_floating): Print 9 digits for IEEE floats.
952 Mon Sep 23 15:50:07 1991 John Gilmore (gnu at cygnus.com)
954 * Makefile.in: Roll VERSION to 4.1.1.
955 * source.c (line_info): Peter Schauer fixes a bug I introduced in
958 Fri Sep 20 16:10:52 1991 John Gilmore (gnu at cygnus.com)
962 * Makefile.in (VERSION): Set to 4.1.
963 * language.c (set_language_command): Print useful help message,
964 and restore the language string after giving help.
965 * valprint.c (typedef_print): Print typedef in C or M2.
966 * symtab.c (list_symbols): Use it.
967 * main.c (main): Avoid any output before (gdb) prompt when -q.
968 * language.c (set_language_command): Handle errors by restoring
969 the language string to its current state (fix from A. Beers).
970 * doc/gdbint.texinfo: Roll in information from README. Rearrange
971 "how to install" and "how to print the doc" stuff so it drops
973 * configure.in: Rename rtpc CPU to romp to match config.sub.
974 * README, WHATS.NEW, TODO: Update for gdb-4.1.
976 Fri Sep 20 17:39:14 1991 Roland H. Pesch (pesch at cygnus.com)
978 * doc/gdb.texinfo: Updates from ChangeLog. set/show write,
979 autoloading shared libs, copyright etc on GDB startup, clean up $_
980 and $__ index refs, set/show listsize and related updates to list
981 cmd. New host/target configs.
983 Fri Sep 20 15:46:00 1991 Roland H. Pesch (pesch at cygnus.com)
985 * doc/Makefile: generate aux version-no file doc/gdbVN.m4
986 from main Makefile.in version definition
987 doc/gdb.texinfo: use version recorded in doc/gdbVN.m4 for current
989 Makefile.in (setup-to-dist): generate doc/gdbVN.m4
991 * doc/gdb.texinfo: merge new language-switching and lang-specific
994 Fri Sep 20 15:00:57 1991 Per Bothner (bothner at cygnus.com)
996 * mcheck.c: Add __ONEFILE kludge to allow compilation by non-ANSI
997 compilers (which may lack stddef.h).
999 Fri Sep 20 13:29:42 1991 John Gilmore (gnu at cygnus.com)
1001 * dbxread.c (read_dbx_symtab, process_one_symbol): N_FN and
1002 N_WARNING are the same except for the N_EXT bit, so just use their
1003 values alone, rather than OR-ing them with N_EXT.
1005 Fri Sep 20 12:27:55 1991 Stu Grossman (grossman at cygnus.com)
1007 * mipsread.c (parse_lines): Deal with negative extended line
1010 * c-exp.y, m2-exp.y: #define yyerrflag and yynerrs to avoid
1011 global symbol conflicts.
1013 Fri Sep 20 02:28:15 1991 John Gilmore (gnu at cygnus.com)
1015 * .gdbinit: Move 'set complaints' to top, so it runs even in
1016 case we aren't debugging GDB.
1017 * language.c (_initialize_language): Fix type check and range
1018 check documentation strings.
1019 * utils.c (!HAVE_VPRINTF): Define vfprintf as a function, so
1020 language.c can use it. (Though language.c should really not be
1021 handling warnings/errors the way it does, FIXME.)
1022 * symtab.c (lookup_primitive_type): const lint.
1024 Bugfix from Peter Schauer:
1025 * source.c (lines_to_list): Make signed, to avoid comparison
1026 going unsigned and complaining that -3 is too high for 21 lines.
1027 * stack.c (lines_to_list): Ditto.
1029 Thu Sep 19 23:33:41 1991 John Gilmore (gnu at cygnus.com)
1031 * Makefile.in (HFILES): Add minimon.h.
1032 (VERSION): Roll version number to 4.0.95.
1033 (gdb.tar.Z, make-proto-gdb.dir, setup-to-dist, gdb-XXX.tar.Z):
1034 New rules for building distributions. Normal distribution
1035 is built by doing `make -f Makefile.in gdb.tar.Z' in the directory
1036 one level up from here; it calls make-proto-gdb.dir to build a
1037 directory `proto-gdb' which is an image of the release. The old
1038 `gdb.tar.Z' rule still works too.
1039 * config.sub, configure: Roll in latest from ..
1041 Thu Sep 19 17:41:24 1991 Roland H. Pesch (pesch at cygnus.com)
1043 * doc/gdbint.texinfo: Reorder contents; reorganize new-host,
1044 new-target, and new-config chapters; fix minor typos; come closer
1045 to usual GNU markup conventions for @file @samp @code @var.
1047 Thu Sep 19 17:04:12 1991 Per Bothner (bothner at cygnus.com)
1049 Patches from Peter Schauer <pes@regent.e-technik.tu-muenchen.de>:
1050 * mipsread.c (parse_partial_symbols): Enter the name of all
1051 structs/unions... into the psymtab so we can access them if the
1052 symtab is not read in.
1053 * mips-tdep.c: Remove some unneeded #includes.
1054 * xconfig/dec3100: Add HAVE_STRSTR.
1056 Thu Sep 19 15:14:23 1991 John Gilmore (gnu at cygnus.com)
1058 * Makefile.in: Circumvent Sun Make bug on *-exp.tab.o.
1059 * c-exp.y, m2-exp.y: Lint.
1060 * m2-exp.y: Avoid using yytname[] which is a Bison-ism.
1061 * valprint.c (val_print_fields): Check for stub type.
1062 * mipsread.c (_initialize_mipsread): Avoid using
1063 builtin_type_void at initialize time.

1066 Wed Sep 18 15:55:51 1991 John Gilmore (gnu at cygnus.com)
1068 Merge multiple-language support, and partial Modula-2 support,
1069 from Andrew Beers <beers@cs.buffalo.edu>.
1071 * i387-tdep.c: New file, consolidates most 80387 support,

1091 (process_coff_symbol): #if 0'd for functions and params as above.
1092 (read_enum_type): Recognize Modula-2 BOOLEAN.
1093 * symtab.c (add_param_to_type): #if 0'd function to add a

1129 TYPE_CODE_BOOL and TYPE_CODE_CHAR.
1131 * expression.h (enum exp_opcode): Add Modula-2 specific opcodes.
1132 * expprint.c: Look up expression opcodes in language-specific

1165 Tue Sep 17 08:37:41 1991 John Gilmore (gnu at cygint.cygnus.com)
1167 Add Andrew Beers' changes for Modula-2 support. His ChangeLog
1168 entries are enclosed herein. Not all of these changes
1169 have been merged into the master GDB sources -- check the
1170 ChangeLog above here for the merge log.
1172 Mon Jun 3 17:05:45 EDT 1991
1174 m2-exp.y Created. Tested outside of GDB for a few days. Proper
1175 operators were added, C specific operators and tokens
1176 removed. yylex() revamped to some extent. Still things
1177 missing from the grammar, such as sets.
1178 Tested for two weeks in GDB v3.5.
1180 Tue Jun 11 17:23:48 EDT 1991
1182 m2-exp.y Added boolean constants TRUE and FALSE to the grammar
1183 so they are built-in. Sort of a hack.
1185 Fri Jun 14 12:53:51 EDT 1991
1187 m2-exp.y Added range checking for numeric constants. Any numeric
1188 constant is assumed to be of builtin type INTEGER unless:
1189 (1) it is octal or hexadecimal, in which case it is a
1190 CARDINAL; (2) it is too big to fit into an INTEGER, in
1191 which case it is a CARDINAL.
1192 eval.c Added simple range checking for +, -, and * on integers.
1193 Doesn't work very well for *, since 6 * 1,000,000,000 =
1194 1,705,032,704, which fails the simple test of result >=
1195 first_operand, no matter in what order the operands are.
1197 Tue Jun 18 14:11:30 EDT 1991
1199 Broke the parser into parts, one containing the C grammar and the other
1200 containing code to be shared by all of the grammars.
1202 The following files no longer exist:
1207 The following files were added:
1209 c-exp.y (The C grammar)
1210 m2-exp.y (The Modula-2 grammar)
1211 parser-code.c (Code that is shared by the above grammar)
1215 Makefile.dist Changed to reflect the above dependencies. NOTE: It is
1216 now necessary to use the Bison compiler compiler, since it
1217 will generate function/variable prefixes other than yy.
1219 Tue Jun 18 16:47:49 EDT 1991
1221 symtab.[ch] Added the external variable working_lang, than holds the
1222 value of the current working language.
1223 Added the ennumerated type language_mode, with the values
1224 language_auto and language_manual, the former meaning that
1225 GDB sets working_lang as needed, and the latter meaning
1226 that the value of working_lang is totally under user
1228 symtab.[ch] Added the Modula-2 pervasive types INTEGER, CARDINAL,
1229 REAL, BOOLEAN and CHAR. Also added the type codes
1230 TYPE_CODE_BOOL and TYPE_CODE_CHAR.
1231 utils.c Added set_language_command and show_language_command to
1232 implement the GDB support commands "set language" and
1234 expression.h A number of identifiers were added to the type exp_opcode
1235 to facilitate Modula-2 builtin functions, integer
1236 division, and array indexing.
1238 Wed Jun 19 13:25:58 EDT 1991
1240 language.h Added the macro STRICT_TYPE, which evaluates to non-zero
1241 if the language specified by working_lang requires the use
1242 of strict typing of expressions. Eventually, even this
1243 will be able to be changed by the user.
1244 Added the macro RANGE_CHECK, which evaluates to non-zero
1245 if the language specified by working_lang requires the
1246 checking of a value against the domain of its type.
1247 Eventually, even this will be able to be changed by the
1249 language.[ch] Predicates involving types (simple_type, ordered_type,
1250 same_type, integral_type, numeric_type, character_type,
1251 boolean_type, float_type) are added. These predicates are
1252 based on the current value of working_lang, and are handy
1255 Wed Jun 19 15:39:34 EDT 1991
1257 eval.c Added the function type_array_rank which computes the rank
1259 valarith.c Added the funtion value_bool, which when given a integer
1260 value.h value (ie. struct value *) as an argument, it returns a
1261 boolean value (ie. struct value *) true if that integer
1262 is non-zero, and a boolean value false otherwise.
1263 valprint.c Added cases for TYPE_CODE_BOOL, so Modula-2 BOOLEAN values
1264 will print out properly.
1266 Wed Jun 19 16:36:34 EDT 1991
1268 valops.c Added the function value_capitalize, which returns it
1269 value.h argument capitalized if its argument is a lowercase
1270 letter, or the argument unchanged if its argument is not a
1272 valarith.c Added the function range_check_p, which returns non-zero
1273 value.h if its value argument is between the integral bounds upper
1275 Added the function range_check_enum_p, which makes sure
1276 that its value argument is a valid member of the domain of
1278 Added the function range_check_range_p, which makes sure
1279 its value argument lies between the upper and lower bounds
1280 of its type argument, which must be a ranged type.
1281 Added the function check_array_index, which range and type
1282 checks an index of an array.
1283 Added the function value_multi_subscript, which computes
1284 array[idx1,idx2...idxN], given a value array and an array
1285 of values representing indicies.
1286 values.c Changed value_from_long to work with TYPE_CODE_CHAR and
1287 unpack_long to work with TYPE_CODE_BOOL and
1290 Wed Jun 19 18:04:08 EDT 1991
1292 symtab.c Stored pervasive types in a structure and make
1293 lookup_pervasive_type() a lookup function that was based
1294 on working_lang. If lookup_pervasive_type() returned
1295 non-zero, then that value was returned (a fix, since
1296 before it simply wouldn't return the pervasive type.)
1297 language.h Added the macro CAST_IS_CONVERSION, which evaluates to
1298 non-zero if the language specified by working_lang means
1299 "conversion" when it says "cast".
1300 valops.c Added the function value_real_cast(), which performs a
1301 value.h *cast*, not a *conversion*, which is what value_cast()
1302 does when it can. In particular,
1303 value_cast(<float_type>,4) = 4.0, while
1304 value_real_cast(<float_type>,4) = some mess.
1305 eval.c Modula-2 builtin functions implemented: ABS, CAP, CHR,
1306 parser-code.c FLOAT, HIGH, MAX, MIN, ODD, ORD, TRUNC, and VAL.
1307 expression.h Added macros MAX_OF_TYPE and MIN_OF_TYPE to work with MAX
1308 and MIN on integral types. *NOTE*: These are currently
1309 hardcoded to work only if there are 8 bits per storage
1311 eval.c Made logical functions call value_bool to return a
1312 properly typed boolean value, based on working_lang.
1314 Thu Jun 20 11:55:27 EDT 1991
1316 valprint.c Types now print out in a Modula-2 fashion. This works for
1317 the cases when the type is printed out step-by-step, that
1318 is, it doesn't work when the name of a structured type
1319 (which includes the keyword "struct", etc.) is simply
1321 FIXME: Perhaps this is bad. Parts of it seem to kludgey,
1322 since type specifications in C and Modula-2 are very
1323 different. The C printing of a type is very recursive,
1324 whereas in Modula-2 it is generally very simple. C has
1325 type prefixes and suffixes, which have no real analogue in
1326 Modula-2. Maybe type_print() should call a language
1327 specific type printer. This is also advantageous if we
1328 compile GDB to exclude some of the languages. We'll just
1329 leave those functions out.
1331 Thu Jun 20 16:57:10 EDT 1991
1333 dbxread.c When reading the complete symbol table in (via
1334 psymtab_to_symtab()), the number and types of function
1335 arguments are added to a function type. define_symbol()
1336 calls add_param_to_type() to accomplish this.
1337 Assumption: when we come across a function definition
1338 (N_FUN symbol with an 'f' or 'F' in the name), its
1339 arguments will appear before another function definition.
1340 When a function is found, a pointer to its type is placed
1341 in the global in_function_type. Changes that
1342 add_param_to_type() makes are to this global.
1343 valprint.c The type of a function now includes (for Modula-2) the
1344 types of its parameters.
1345 eval.c Type checking and a check for the proper number of
1346 arguments is now done for function calls. Not sure of the
1347 impact this has on C++ member function yet.
1349 Thu Jun 20 19:58:48 EDT 1991
1351 valprint.c Rewrote the type printer. Broke it into two language
1352 specific parts, adding the functions type_print_m2() and
1354 An unfortunate consequence is this: if you debugging a C
1355 program in Modula-2 mode (why?), info types does not work
1356 well with regular expressions, since the types are printed
1357 out in Modula-2 terminology, but stored in C terminology.
1358 language.[ch] Added the functions new_type_last(), type_keyword(), and
1359 type_sep() to aid in the printing of typedefs.
1360 symtab.c Made the printing of typedefs as language independent as
1361 possible through calls to new_type_last(), type_keyword(),
1364 Fri Jun 21 11:50:26 EDT 1991
1366 dbxread.c Check all incoming ennumerated types. If it looks like
1367 Modula-2's BOOLEAN type, then change the type_code of the
1368 type to TYPE_CODE_BOOL so we can process it as a boolean
1370 valprint.c Replaced some of the 0x%x with calls to sprintf and
1371 hexformat() in val_print().
1372 language.[ch] Added the function hex_to_string(), which converts its
1373 integral argument to a hexadecimal number (format is
1374 language based) and returns the result as a string.
1376 Mon Jun 24 12:25:07 EDT 1991
1378 valprint.c Some functions call type_print_1() directly, instead of
1379 value.h using type_print(), so they can specify where (column) to
1380 print things. Since type_print() takes care of language
1381 dependence, that needs to be called first. Added a
1382 parameter depth to type_print() (so it is now like
1383 type_print_1). Changed type_print to type_print_at, and
1384 made type_print a macro that passes a depth argument of
1386 symmisc.c Changed all calls to type_print_1 to calls to
1388 Makefile.dist Made it possible to build GDB for a specific set of
1389 depend languages. Do this by passing a definition for the macro
1390 LANGS to make. LANGS should be a string containing a
1391 space-separated list of language names (ie. LANGS="c m2").
1392 The default is to build all languages. Note that grammar
1393 files must follow the naming convention of <lang>-exp.y.
1394 gdb.lang This holds the current value of the LANGS macro. It is
1395 examined every time make is called, and is updated if
1397 eval.c Added #ifdef _LANG_<lang> to these files.
1398 expread.c Still need to add them to dbxread.c and coffread.c.
1406 Mon Jun 24 16:33:11 EDT 1991
1408 language.[ch] Added the functions hexformat_pre() and
1409 hex_to_string_pre(), which take a prefix argument to
1410 include in the format string. Thus, hexformat_pre("08") will
1411 return "0x08x" (if the working language is language_c).
1412 Made hexformat() and hex_to_string() calls to the above
1413 with "" as the prefix argument.
1415 am29k-pinsn.c, arm-pinsn.c, breakpoint.c, convex-tdep.c, exec.c, core.c,
1416 dbxread.c, i386-pinsn.c, i386-stub.c, i386-xdep.c, i960-pinsn.c,
1417 infcmd.c, inflow.c, m68k-pinsn.c, m68k-stub.c, m88k-pinsn.c,
1418 mips-pinsn.c, mips-tdep.c, ns32k-pinsn.c, printcmd.c, pyr-pinsn.c,
1419 pyr-tdep.c, pyr-xdep.c, remote-vx.c, remote.c, solib.c, source.c,
1420 stack.c, sun386-xdep.c, symfile.c, symm-xdep.c, symmisc.c, tahoe-pinsn.c,
1421 valprint.c, vax-pinsn.c
1423 Changed all occurences of 0x%[0-9]*l*x in printf format strings to
1424 calls to hexformat() and hex_to_string(). Format strings without
1425 the leading "0x" were ignored.
1427 depend Updated to take the above into account.
1430 Tue Jun 25 15:27:18 EDT 1991
1432 symtab.h Added the types range_mode_t, range_check_t, type_mode_t,
1433 and type_check_t to keep track of the current state of
1434 range and type checking.
1435 main.c Added the variables range_mode, range_check, type_mode,
1436 and type_check to record the current state of range and
1437 type checking. Added initialization code to main().
1438 language.h Changed the macros STRICT_TYPE and RANGE_CHECK to examine
1439 the above variables.
1442 Tue Jun 25 17:57:08 EDT 1991
1444 dbxread.c process_one_symbol() updates the variable (enum language)
1445 source_lang based on the extension of the filename
1446 contained in the N_SO sybmol that started this symtab.
1447 When end_symtab() is called, the value of source_lang is
1448 put into the language field.
1449 stack.c select_frame() sets working_lang (and possibly type_check
1450 and range_check) to the language field of the symtab
1451 associated with the frame that is selected if working_mode
1452 is language_auto. If working_mode is language_manual, a
1453 warning is printed and working_lang is not set.
1454 language.c Added the function set_type_range(), which sets the value of
1455 type_check and range_check (if their modes call for
1456 automatic setting) based on the current value of
1457 working_lang. A non-zero argument will cause the current
1458 settings to be output.
1461 Wed Jun 26 14:51:40 EDT 1991
1463 eval.c Added range checks on assignment.
1464 m2-exp.y Added the grammar for sets to the language. Currently,
1465 these do not do anything except print an error message.
1467 Wed Jun 26 17:01:04 EDT 1991
1469 m2-exp.y Added the ability for parse_number() to parse negative
1470 numbers. A global flag is set upon encountering a unary
1471 minus. This was done to make, for example, 1 parse as a
1472 CARDINAL, and not as an integer, per Wirth's examples in
1473 Programming in Modula-2 ed.4.
1474 valprint.c Added support for "set radix 2" by then setting
1475 output_format to 't'.
1476 eval.c Implemented range checking on subrange types. Added calls
1477 to range_check_range_p for BINOP_ASSIGN and BINOP_VAL.
1478 Implemented MIN and MAX for ennumerated types. The
1479 minimum value of an ennumerated type is defined by Wirth
1480 as the first identifier, and the maximum as the last.
1481 m2-exp.y Made octal numbers ending with "B" be characters and those
1482 ending with "C" be numbers, per Wirth's book. (p. 34)
1484 Thu Jun 27 14:11:52 EDT 1991
1486 stack.c select_frame() now only sets working_lang, it does not
1487 notify the user. If working_mode is language_manual, then
1488 a warning is issued once.
1489 main.c At the end of each call to execute_command(), working_lang
1490 is checked against the local static (enum language)
1491 current. If they differ and working_mode is
1492 language_auto, the new settings of language, type and
1493 range checking are printed out.
1494 stack.c Modified frame_info() to include the language of the
1495 current frame in the output of "info frame".
1496 language.[ch] Added the function language_str() which returns the name
1497 of the current language.
1499 Fri Jun 28 15:33:14 EDT 1991
1501 m2-exp.y Added the built-in procedures INC, INCL, DEC, and DECL to
1502 the language. INCL and DECL currently cause an error,
1503 since sets are not implemented yet. INC and DEC are
1504 implemented as PREINCREMENT/PREDECREMENT with one
1505 argument, and as ASSIGN_MODIFY with two arguments.
1506 eval.c Added type checking to the above cases.
1507 value.h Added not_lval_constant to the lval_type ennumerated type.
1508 not_lval_constant means that the value is a constant
1509 value; that is 3 or 'a' or TRUE, not as in a constant
1510 identifier. This is used to help coerce numbers such as 3
1511 to either signed or unsigned numbers.
1512 valops.c Added the function value_coerce_constants() which coerces
1513 constant integers as following: if one is a constant and
1514 the other is not, the constant's type is set to the type
1515 of the other argument. If both are constants and one is
1516 signed, the other is converted to a signed constant.
1518 Sat Jun 29 17:26:29 EDT 1991
1520 valarith.c Added a better range checker. It now checks range
1521 (successfully) on integral operations [+-] (signed and
1522 unsigned) for any C sized type. Still does not work well
1523 for multiplication.)
1524 int_in_size() returns an integer that is coerced to fit into
1525 specified number of bytes.
1527 Mon Jul 1 13:04:14 EDT 1991
1529 language.[ch] Added the function binop_result_type(), which returns the
1530 builtin (struct type *) type that would be the result of a
1531 binop on the two values V1 and V2.
1533 Wed Jul 3 19:22:53 EDT 1991
1535 source.c Extended source_info() to include the source language in
1536 the output from "info source".
1538 Fri Jul 5 13:48:52 EDT 1991
1540 utils.c Moved the support functions for the GDB set/show commands
1541 dealing with language into language.c.
1542 language.c Added the function language_info(), which displays info
1543 about the current working language, type and range check
1544 settings. Called via the GDB command "info language".
1545 Added an initialization routine _initialize_language(),
1546 that sets defaults for the language, type and range
1547 variables and sets up the new GDB commands.
1548 main.c Language setup moved to language.c.
1551 Mon Jul 8 10:10:22 EDT 1991
1553 valarith.c Debugged the range checker for arithmetic. Still does not
1554 work for multiplication very well.
1556 Mon Jul 8 12:40:37 EDT 1991
1558 language.[ch] Added the function value_true() which returns non-zero if
1559 its argument represents a boolean true value.
1560 breakpoint.c Changed breakpoint_cond_eval() to call value_true() to
1561 check the truth of an expression.
1563 Thu Jul 11 12:51:34 EDT 1991
1565 language.[ch] Added the predicate structured_type(), which returns
1566 non-zero if the argument is a structured type.
1567 Added the predicate pointer_type(), which returns non-zero
1568 if the argument is a pointer type.
1569 eval.c Added the ability to do addition and substraction on
1570 pointers and integers. This case simply bypasses the
1573 Thu Jul 11 14:41:42 EDT 1991
1576 Added the symbol N_DEFD (0x4a) which is a definition
1577 module dependency that is used by the GNU Modula-2
1578 compiler and the linker. It is not important to GDB,
1579 except that [dbx|coff|mips]read.c should ignore these
1582 Fri Jul 12 16:07:00 EDT 1991
1584 valprint.c Changed the TYPE_LENGTH(type) >= 0 to TYPE_LENGTH(type) >
1585 0 in val_print(). Also added statements to the else part
1586 to coerce type (argument to val_print) to a pointer type
1587 if it is an "array of unspecified length".
1588 valops.c Added the function value_m2_string(), which returns a
1589 (value) value which is a constant string, whose type is
1590 (ARRAY [0..n] OF CHAR). The length field of the type
1591 structure is set to zero, so it will be interpreted as an
1592 "array of unspecified length".
1593 stack.c Moved the language/frame mismatch check to
1594 main.c:execute_command().
1595 main.c The working language is recorded each time
1596 execute_command() is executed. If working lang has
1597 changed during its execution, then the new
1598 language/type/range info is printed out for the user. If
1599 the working language does not match the language of the
1600 frame, a warning is issued.
1602 Sat Jul 13 16:16:39 EDT 1991
1604 eval.c Moved all the type-checking stuff for operators to
1605 language.[ch] language.c. This is so we can keep language-specific
1606 stuff (like for what type operators are defined) in
1608 language.[ch] Added the function binop_type_check(), which checks to see
1609 if its two (value) arguments are type-compatible with its
1610 opcode argument. The opcode should represent an operation
1611 involving an operator. Also added the macro function
1612 unop_type_check, which calls binop_type_check with a
1613 NULL second argument.
1614 expprint.c Added Modula-2 operators to the op_print_tab, so info
1615 expression.h break works correctly. Also added "op_string", which
1616 returns the string corresponding to the (enum exp_opcode)
1617 opcode that is its argument.
1620 Sat Jul 13 18:26:18 EDT 1991
1622 coffread.c Added code to record the type of function arguments with
1623 each paricular function. Code is very similar to that
1625 dbxread.c Moved add_param_to_type() to symtab.c
1626 symtab.[ch] Added function add_param_to_type() from dbxread.c
1628 *** NOTE: The above additions have not been tested.
1630 Mon Jul 15 12:50:47 EDT 1991
1632 langauge.[ch] Added the functions type_error and range_error, which work
1633 like error() except if the type/range mode is set to
1634 *_mode_warn, then they do not do a return_to_top_level(),
1635 but merely print a warning.
1636 Also changed [set|show]_[type|range]_command() to support
1637 the new "warn" feature.
1639 Thu Jul 18 17:50:54 EDT 1991
1641 mipsread.c Added code to record the type of function arguments with
1642 each particular function. Code is very similar to that
1645 *** NOTE: The above additions have not been tested.
1647 Fri Jul 19 11:19:10 EDT 1991
1649 defs.h Added macros MAX_OF_SIZE, MIN_OF_SIZE, UMAX_OF_SIZE, and
1650 UMIN_OF_SIZE, which when given a size of a numeric type,
1651 return the maximum and minimum value it can hold. UMAX...
1652 and UMIN... return the result for unsigned types.
1653 symtab.h Added the macros MAX_OF_TYPE and MIN_OF_TYPE to operate on
1654 struct types. They call above macros.
1655 dbxread.c Renamed the MAX and MIN_OF_TYPE macros to ..._OF_CTYPE to
1656 avoid a name conlict with the above.
1657 c-exp.y Added range checking on numeric constants in
1658 parse_number() for completeness.
1659 valarith.c Made binop_user_defined_p() and unop_user_defined_p()
1660 return 0 if working_lang is not language_c.
1662 Thu Aug 8 14:17:22 EDT 1991
1666 breakpoint.c Documentation strings of some commands changed to
1667 eliminate the references to the C language where
1670 Tue Aug 13 15:48:03 EDT 1991
1672 m2-exp.y Added qualified identifiers to the grammar. The semantics
1673 are slightly different from those of the GDB operator ::
1675 m2-exp.y Added a rule to each grammar of the form: start ::= exp |
1676 type_exp, where type_exp is any valid type expression.
1678 eval.c Added the opcode OP_TYPE, and an error case in eval.c.
1679 printcmd.c Modified ptype_command() so it actually parses the input
1680 (necessary for type expressions with scope qualifiers).
1681 Added the function ptype_eval() which expects an
1682 expression composed of one OP_TYPE element.
1683 *.[ch] Replaced all occurences of parse_c_expression with
1685 *.[ch] Replaced all occurences of parse_c_1 with parse_exp_1
1687 [End of ChangeLog entries from Andrew Beers for Modula-2 support.]
1689 Mon Sep 16 17:19:46 1991 John Gilmore (gnu at cygnus.com)
1691 Small fixes from Peter Schauer:
1693 * infrun.c (child_attach): Lint.
1694 * solib.c (find_solib): Handle shared libs version 2.
1696 Small fixes from David Wood:
1698 * xm-ultra3.h (SYS_SIGLIST_MISSING): Typo.
1702 * remote-vx.c: Move <stdio.h> to top, for FILE. Fix from
1703 John S <basrai%kanga.dnet@c3po.sm-alc.af.mil>.
1705 * utils.c (wrap_here): Avoid wrap action of fputs_filtered if
1706 chars_per_line is at maximum (user typed `set width 0'). Fix
1707 from Andreas Schwab <schwab@ls5.informatik.uni-dortmund.de>.
1709 Tue Sep 17 17:31:04 1991 Stu Grossman (grossman at cygnus.com)
1711 * coredep.c: include ptrace.h where necessary.
1712 * mipsread.c(parse_lines): fix unsigned char problem that was
1713 messing up line numbers on SGI's and possibly other MIPS based
1715 * infrun.c (child_create_inferior): use better test to check
1716 return val from setpgrp().
1717 * tm-irix3.h, xm-irix3.h, tconfig/irix3, xconfig/irix3: add these
1718 for sgi/irix support.
1720 Wed Sep 18 04:33:31 1991 Per Bothner (bothner at cygnus.com)
1722 * mipsread.c (parse_symbol): Put non-static procedures
1723 in the global block.
1725 Fri Sep 13 00:14:52 1991 John Gilmore (gnu at cygnus.com)
1727 Patch together `text_start' and `text_end' for 29K port.
1729 * exec.c (exec_command): If NEED_TEXT_START_END, define the
1730 variables and set them based on the exec file.
1731 * am29k-tdep.c: declare text_start.
1732 * valops.c (call_function_by_hand): declare text_end.
1734 * inferior.h: Eliminate CANNOT_EXECUTE_STACK in favor of
1735 defining CALL_DUMMY_LOCATION as BEFORE_TEXT_END. This is
1736 because machines that do this will also have to know to
1737 set NEED_TEXT_START_END. Besides, it was a redundant way to
1739 * tm-29k.h, tm-convex.h, tm-np1.h: Eliminate
1740 CANNOT_EXECUTE_STACK, define CALL_DUMMY_LOCATION and
1741 NEED_TEXT_START_END.
1743 Thu Sep 12 00:22:24 1991 John Gilmore (gnu at cygint.cygnus.com)
1745 AMD 29000 changes from David Wood <wood@david.ultra.nyu.edu>:
1747 * Makefile.in (CLIBS): Put XM_CLIBS and TM_CLIBS at end.
1748 Pass MUNCH_DEFINE to munch whenever we run it.
1749 * am29k-pinsn.c (print_insn): Handle NOP specially. Avoid %#x
1750 format string; use 0x%x instead.
1751 * am29k-tdep.c: Use DUMMY_SAVE_GREGS and RETURN_REGNUM.
1752 * ultra-xdep.c, xm-ultra.h: New files for Ultracomputer host system.
1753 * xm-rtbsd.h: New host support for RT/PC running BSD Unix.
1754 * inflow.c: Handle `short' process group IDs.
1755 * infptrace.c (fetch_register): Support CANNOT_FETCH_REGISTER,
1756 and check for ptrace errors.
1757 * coffread.c (SDB_REG_TO_REGNUM): Define if not already.
1758 (coff_symfile_init): Initialize text_bfd_scnum.
1759 (read_coff_symtab): Use it to find the text [and absolute?] sections.
1760 * ../config.sub: Add vendor nyu and os "sym[1-9]*".
1761 * configure.in: Add hosts rtpc-*-* and a29k-*-*.
1762 Merge target arm case with other "easy" cases. Add target
1763 cases a29k-*-none (rehack of am29k), a29k-*-kern (remote to
1764 Ultracomputer kernel), and a29k-*-sym1 (ultracomputer OS's user
1766 * minimon.h, remote-adapt.c, remote-mm.c: Add.
1767 * munch: Cope with RT/PC putting fns in data segment.
1768 Restore ability to override `nm' by specifying MUNCH_NM.
1769 * xconfig/rtbsd, xconfig/ultra3: New host systems.
1770 * tconfig/a29k: Rename from tconfig/am29k. Add remote-mm
1771 and remote-adapt. Remove encapsulated coff #define's (the
1772 support should go in BFD, and gdb shouldn't know or care).
1773 * tconfig/a29k-kern: Same, but for remote kernel debugging.
1774 * tconfig/ultra3: For debugging user processes on Ultra3/Sym1.
1775 * tm-29k.h: Update BADMAG (though it should go away).
1776 Allow the register definitions to be overridden in another
1777 tm-file. Fix SR_REGNUM. Add a mess of _REGNUM's. Separate
1778 RETURN_REGNUM from GR96_REGNUM and DUMMY_SAVE_GREGS from
1779 DUMMY_SAVE_GR96, for handling kernel calling conventions
1780 that use GR64+ rather than GR96+.
1781 * tm-ultra3.h: New file, for use on Ultra3 Unix as well as for
1782 remote debugging of Ultra3 kernel. Includes tm-29k.h and
1783 overrides various things.
1785 * remote-mm.c (mm_attach, mm_wait): Handle attach like
1786 child_attach does, making a clean stop in the newly attached
1788 * remote-eb.c: Lint.
1790 * coffread.c: Make coffread independent of any particular
1791 variant of COFF. Avoid #include-ing any particular one except
1792 internalcoff.h. BFD now passes key values for symbol reading
1793 as part of its coff_data structure (LINESZ, SYMESZ, AUXESZ,
1794 and the symbol masks and shifts); use them.
1795 Remove obsolete end_of_text_addr.
1797 * exec.c: Remove unused include files.
1799 Wed Sep 11 19:38:44 1991 John Gilmore (gnu at cygint.cygnus.com)
1801 * Makefile.in (documentation targets): Pass $(M4).
1802 Bugfix from eggert@twinsun.com (Paul Eggert).
1804 * stack.c (down_silently_command): Check for stack existence.
1806 Tue Sep 10 23:08:29 1991 John Gilmore (gnu at cygint.cygnus.com)
1808 * Makefile.in (VERSION): Update to 4.0.3.
1810 Tue Sep 10 09:19:29 1991 John Gilmore (gnu at cygint.cygnus.com)
1812 * core.c (core_file_command): Print frame at coredump with
1813 its level number, by calling print_stack_frame.
1814 * frame.h: Add selected_frame_level, print_stack_frame.
1815 * frame.h, stack.c: Remove print_sel_frame, print_selected_frame.
1816 * convex-tdep.c, convex-xdep.c, infcmd.c, inflow.c, infrun.c:
1817 Change print_sel_frame and print_selected_frame callers to
1820 * dbxread.c (read_ofile_symtab): Avoid empty else clause.
1821 * symfile.c (free_named_symtabs): Ditto.
1822 * main.c (main): wrap_here needs an arg.
1823 * solib.c (find_solib): Avoid memory access if _DYNAMIC is zero.
1824 (solib_add): Avoid noise.
1825 (solib_create_inferior_hook): Lint.
1826 (sharedlibrary_command): Move dont_repeat to here.
1827 * utils.c (error): Call wrap_here to force buffered output.
1829 Small patches from Peter Schauer:
1831 * coffread.c (start_symtab): Free any existing line_vector before
1833 (read_coff_symtab): Ditto for type_vector.
1835 * source.c (lines_to_list): New variable, replacing function.
1836 (all uses): Use as variable.
1837 (_initialize_source): Add 'set listsize' and 'show listsize'.
1838 * utils.c (lines_to_list): Remove function.
1839 * stack.c (print_frame_info): Use as variable.
1840 * defs.h (lines_to_list): Remove declaration.
1842 Mon Sep 9 13:45:57 1991 John Gilmore (gnu at cygint.cygnus.com)
1844 * breakpoint.c (insert_breakpoints): Restore warning about
1845 the program might be running in another process, but only for
1846 systems with this brain death (#ifdef ONE_PROCESS_WRITETEXT).
1847 * xm-hp300bsd.h, xm-mips.h, xm-vax.h: Define it.
1849 * utils.c (error): if error_pre_print is set, print the string
1851 * main.c (main, print_gnu_advertisement, print_gdb_version):
1852 Reformat legalese so it always prints, but acts as an "I'm here"
1853 message while symbols are being read. If any errors occur,
1854 print a few newlines to set off the message and start it at the
1855 left margin. Remove mention of "help" command, and don't yak
1856 about symbol reading.
1857 (catch_errors): Error string is now printed first in case of
1859 * command.c (undef_cmd_error, lookup_cmd): On undefined command,
1860 suggest the "help" command.
1862 * Makefile.in (VERSION): Set to 4.0.2.
1864 Thu Sep 5 23:49:48 1991 John Gilmore (gnu at cygint.cygnus.com)
1866 * .gdbinit: Remove useless "rr" command. Set complaints
1867 to 1 for people debugging gdb.
1869 * breakpoint.c, remote-vx.c: Reword strings printed by
1870 catch_errors callers.
1872 Wed Sep 4 11:07:50 1991 John Gilmore (gnu at cygint.cygnus.com)
1874 * WHATS.NEW: "history write -> history save". Doc "write on/off".
1875 (Fix from kenc@viewlogic.com.)
1877 Fix some infrastructure to be able to cope with host and target
1878 machines with different sized basic types (ints, ptrs, etc).
1879 (Idea from pierre@la.tce.com (Pierre Willard).)
1881 * values.c (value_from_longest): Rename from value_from_long.
1882 Handle pointer types as well as integers, so that targets with
1883 different pointer sizes from the host can be accomodated.
1884 * breakpoint.c, convex-tdep.c, eval.c, expprint.c, printcmd.c,
1885 valarith.c, valops.c, valprint.c, value.h, values.c: Rename
1886 uses of value_from_long to value_from_longest.
1887 * eval.c, findvar.c, printcmd.c, valarith.c, valops.c: Pass
1888 the correct pointer type to value_from_long{est}.
1890 * doc/gdb.texinfo ($_, $__): Describe types of these variables.
1892 * remote-vx.c: Remove obsolete code for calling functions via
1893 vxworks kludge interface (it referenced value_from_long).
1895 * valops.c (value_string): Find malloc with lookup_misc_func, not
1898 Tue Sep 3 18:37:46 1991 John Gilmore (gnu at cygint.cygnus.com)
1900 Make writing to files work properly. (Fixes to BFD are also needed.)
1902 * core.c (core_open): Open file ourselves, read or r/w, depending on
1903 write_files. Use bfd_fdopenr.
1904 * gdbcore.h (write_files): New variable.
1905 * exec.c (write_files): Define variable, add set&show for it.
1906 (exec_file_command): Use write_files to open for read or r/write.
1908 Make shared library reading happen automatically. These changes
1909 are mostly from Peter Schauer <pes@regent.e-technik.tu-muenchen.de>.
1911 * inferior.h (stop_soon_quietly): Add to exported variables.
1912 * infrun.c (child_create_inferior): call solib hook, if defined.
1913 (child_attach): call solib hook, if defined.
1914 * solib.c: Include inferior.h. Add from_tty to so_list as kludge.
1915 (find_solib): Use lookup_misc_func rather than hand-rolled.
1916 (symbol_add_stub): New stub for catch_errors.
1917 (solib_add): Avoid output if !from_tty. Catch errors rather
1918 than just calling symbol_file_add and bombing.
1919 (solib_create_inferior_hook): Interface with the target process
1920 to let it read and alloc shared libs, then figure out what it did.
1922 * core.c (validate_files): Fix typo, soften warning.
1923 (Fix from Hiroto Kagotani <kagotani@cs.titech.ac.jp>.)
1925 * utils.c (fputs_demangled): Avoid duplicate printing if
1926 demangling is off. (Fix from J.T. Conklin <jtc@cayenne.com>.)
1928 * infrun.c (proceed): Cast -1 to (CORE_ADDR) before comparing.
1929 (Fix from pierre@la.tce.com (Pierre Willard).)
1931 * main.c (catch_errors): Change argument to a char * from an int,
1932 since a char * can point to a struct full of glop, but an int
1933 is not guaranteed to be able to hold a pointer.
1934 * breakpoint.c (breakpoint_cond_eval, bpstat_stop_status,
1935 breakpoint_re_set_one, breakpoint_re_set): Adapt.
1936 * core.c (core_open, solib_add_stub): Adapt.
1937 * remote-vx.c (symbol_stub, add_symbol_stub, callers): Adapt.
1939 Wed Aug 28 18:18:05 1991 John Gilmore (gnu at cygint.cygnus.com)
1941 * Makefile.in: Update VERSION to 4.0.1. Evade GNU Make bug
1942 by adding .NOEXPORT target.
1944 Fri Aug 23 17:14:25 1991 John Gilmore (gnu at cygint.cygnus.com)
1948 * Makefile.in (VERSION): Roll to 4.0.
1949 (gdb.tar.Z): Make refcard.ps as well, for shipment.
1951 Fri Aug 23 14:07:09 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1953 * doc/gdb.texinfo: minor rewordings, crossref to ptype from print,
1956 * doc/Makefile, Makefile.in: generate "gdb-all.texi" rather than
1959 * doc/rdl-apps.texi: renamed from rdl-apps.texinfo
1961 * Makefile.in, doc/Makefile, doc/.Sanitize, doc/gdb.texinfo:
1962 reflect above name change
1964 * WHATS.NEW: correct pointer to refcard.
1966 * doc/gdb.texinfo: update New Features, Installing
1968 * doc/gdbint.texinfo: add short description of configure +template
1970 Fri Aug 23 11:46:08 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1972 * doc/gdb.texinfo: update, fix bugs in "Installing" appendix
1974 Fri Aug 23 01:02:00 1991 John Gilmore (gnu at cygint.cygnus.com)
1976 * Makefile.in: Add config.sub, make doc/rdl-apps.texinfo for
1977 tar file, add dependencies for referenced doc files.
1979 Thu Aug 22 22:17:06 1991 Stu Grossman (grossman at cygint.cygnus.com)
1981 * coffread.c, symfile.c, stack.c: saberized.
1983 Thu Aug 22 16:20:27 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1985 * doc/refcard.tex: permuted Essential Commands sec
1987 * doc/gdb.texinfo: new C++ chapter; revised installation appendix;
1989 set/show symbol-reloading
1990 default set complaints 0
1992 RET-repeat disabled after prompted long displays
1993 processID (attach) interpretation of 2nd GDB cmdline arg
1995 Thu Aug 22 14:05:47 1991 Stu Grossman (grossman at cygint.cygnus.com)
1997 * expread.y, coffread.c, dbxread.c, target.c, mem-break.c,
1998 cplus-dem.c, values.c, valprint.c, symfile.c, remote.c,
1999 breakpoint.c, main.c: lint.
2001 Thu Aug 22 02:02:26 1991 John Gilmore (gnu at cygint.cygnus.com)
2003 Install new configuration scheme for GDB and friends.
2005 * config.sub: Translate ordinary names to three-part names.
2006 * configure: Use three-part names internally.
2007 * configure.in: Translate three-part names to filenames.
2009 * README, WHATS.NEW: Update for gdb-4.0.
2010 * Makefile.in: Roll VERSION to 3.99.
2012 Wed Aug 21 18:21:09 1991 John Gilmore (gnu at cygint.cygnus.com)
2014 * infptrace.c (KERNEL_U_ADDR_BSD): Include a.out.gnu.h.
2015 * i960-tdep.c, m68k-tdep.c, sparc-tdep.c, tm-i960.h,
2016 tm-m68k.h, remote-nindy.c: Change ext_format_XXX structs
2017 to single structures rather than arrays; when passing
2018 their address, use &. This avoids trouble with bdead compilers.
2019 * mcheck.c: Don't include <stdlib.h>; just declare "void abort();"
2020 instead. This avoids portability headaches.
2021 * mips-tdep.c (mips_do_registers_info): Only print FP regs if
2023 * source.c (open_source_file): Avoid ANSI const bdeath by
2024 skipping declaration and then casting result value.
2025 * tm-hp300bsd.h: Clarify comment.
2026 * utils.c (strstr): Result is const char *; ANSI bdeath.
2027 * xm-hp300bsd.h: Define HOST_BYTE_ORDER. Redefine INT_MIN,
2028 since system include file defines it differently from "defs.h",
2029 though the two are equivalent for our purposes.
2030 * tconfig/hp300bsd: Add m68k-tdep.o.
2032 Tue Aug 20 16:01:11 1991 John Gilmore (gnu at cygint.cygnus.com)
2034 * tconfig/sun*4: Remove warnings about system assembler.
2036 Mon Aug 19 13:44:46 1991 John Gilmore (gnu at cygint.cygnus.com)
2038 * mcheck.c: Avoid warning about undeclared abort fn.
2039 * tm-sparc.h (PC_ADJUST): Avoid calling error() from this;
2040 it causes recursive calls to error() when used in cleanups.
2041 To do so requires that we make it a function, so we do.
2042 * sparc-tdep.c (sparc_pc_adjust): New implem of PC_ADJUST.
2043 * utils.c (do_cleanups): Remove the current cleanup from the
2044 chain *before* calling it, in case error() is called from it.
2045 The result won't be pretty, but won't be an infinite loop either.
2047 Mon Aug 19 00:41:04 1991 Michael Tiemann (tiemann at cygint.cygnus.com)
2049 * dbxread.c (read_struct_type): Grok anon structs for C++.
2050 (vb_name, vptr_name): Null terminate these strings.
2052 Fri Aug 16 08:31:03 1991 John Gilmore (gnu at cygint.cygnus.com)
2054 Minor bug fixes from BSD Net2 gdb:
2056 * blockframe.c (get_prev_frame_info): If FRAME_CHAIN_COMBINE
2057 returns 0, there is no previous frame.
2058 * breakpoint.c (commands_command): If !from_tty, don't call
2059 input_from_terminal_p().
2060 * dbxread.c (record_misc_function): Speed up slightly.
2061 (compare_psymbols): Ditto.
2062 * infcmd.c (do_registers_info): Take a second argument to
2063 determine whether to print float registers. "info registers"
2064 does not do so anymore. "info all-registers" does, now.
2065 * mips-tdep.c, pyr-tdep.c (xxx_do_registers_info): Take second
2067 * tm-mips.h, tm-pyr.h (DO_REGISTERS_INFO): Pass second arg.
2068 * inflow.c (initialize_inflow): Set tflags_ours correctly.
2072 * breakpoint.c (bpstat_do_actions): Use a cleanup to restore
2073 executing_breakpoint_commands if we are interrupted by error.
2074 * coffread.c (init_lineno): Avoid problem with zero-sized linetab
2075 versus malloc/free. From: john@labtam.labtam.oz.au (John Carey).
2076 * core.c (solib_add_stub, core_open): Call SOLIB_ADD inside a
2077 catch_errors() so we can setup the frame regardless of whether
2078 the shared libs work.
2079 * ieee-float.c (double_to_ieee_extended): Get exponent from
2080 right place in little-endian systems. From John Carey.
2082 Thu Aug 15 18:43:57 1991 John Gilmore (gnu at cygint.cygnus.com)
2084 * main.c: Remove unused terminating_signals and catch_termination().
2085 (long_options): Terminate with a zero element.
2086 [Bugfix from Atsuo Kawaguchi <atsuo@hark86.harl.hitachi.co.jp>.]
2087 (gdb_readline): Make call-compatible with readline.
2088 (init_signals): Improve comments re vfork vs. signal.
2090 * utils.c (prompt_for_continue): Use new gdb_readline().
2091 If we prompt for continuation, we don't let CR repeat the previous
2092 command, once we get back to a prompt. It's too easy to keep
2093 hitting CR, expecting "--more--" prompts, and have some long
2094 command start repeating on you.
2096 Tue Aug 13 16:17:56 1991 John Gilmore (gnu at cygint.cygnus.com)
2098 * blockframe.c (frameless_look_for_prologue): Speed up by
2099 calling SKIP_PROLOGUE_FRAMELESS_P if it's defined.
2100 * tm-sparc.h (SKIP_PROLOGUE, SKIP_PROLOGUE_FRAMELESS_P):
2101 Define two variants, one faster.
2102 * sparc-tdep.c (sparc_frame_chain): Use target_read_memory
2103 and return zero, rather than giving an error.
2104 (setup_arbitrary_frame): Initialize the PC in the new frame.
2105 (skip_prologue): Add a second arg saying whether we're just
2106 checking for a frameless function or not.
2108 * core.c (core_open, core_close, core_xfer_memory): Move
2109 section table pointers and bfd* into the target_ops.
2110 (core_open): Allow errors in shared lib reading, etc.
2111 (core_files_info): Describe shared library sections.
2113 * exec.c (exec_open, exec_close, exec_xfer_memory, xfer_memory,
2114 exec_files_info, set_section_command): Move section table
2115 pointers and bfd* into the target_ops.
2116 (add_to_section_table): Add BFD to section table.
2118 * target.c (target_xfer_memory, target_info): Pass target to
2119 xfer_memory and target_info functions.
2122 * gdbcore.h: Move struct section_table.
2123 * target.h: New home of struct section_table.
2125 * solib.c (solib_add): New argument is the target_ops whose
2126 section list is to be added to, if any. Reallocate the
2127 sections in that target to add any that come from shared libs.
2128 (throughout) so_sections renamed to sections.
2129 (solib_xfer_memory): Deleted.
2130 * tm-sunos.h (SOLIB_ADD): Add target argument.
2131 (SOLIB_XFER_MEMORY): Delete.
2133 * core.c, exec.c, inftarg.c, remote-eb.c, remote-nindy.c,
2134 remote-vx.c, remote.c, target.c, target.h: Remove add_syms vector
2135 from target_ops. It's the same on all targets. Add two section
2136 pointers to target_ops.
2138 * stack.c (find_relative_frame): Dump ancient algorithm for
2139 "down", just use handy "next" pointers.
2140 (frame_command): Don't error if there is no stack; let user
2143 * inflow.c (new_tty_prefork, new_tty): New prefork routine
2144 modifies static state in the parent process; new_tty itself
2145 runs in the child and modifies the child's file descriptors
2146 to match the saved static state.
2147 * infrun.c (child_create_inferior): Call new_tty_prefork,
2150 * infptrace.c (child_xfer_memory): Add ignored target arg.
2151 * remote-eb.c (eb_xfer_inferior_memory): ''
2152 * remote-nindy.c (nindy_xfer_inferior_memory): ''
2153 * remote-vx.c (vx_xfer_memory): ''
2154 * remote.c (remote_xfer_memory): ''. Rename from
2155 remote_xfer_inferior_memory.
2157 * main.c (main): Only try to attach "corefile" argument if
2158 it starts with a digit.
2160 * symfile.c (symbol_reloading): New "set/show" variable.
2161 (symbol_file_add): Shorten message about symbol reading.
2162 (add_symbol_file_command): Merge with add_syms_addr_command,
2163 since this should work on all targets now.
2164 (stop_whining): Default to zero, to shut up complaints
2165 about bad symbol tables on many systems.
2166 (free_named_symtabs): Just exit unless symbol_reloading.
2168 * xm-sun3os4.h, xm-sun4os4.h: Define BROKEN_LARGE_ALLOCA,
2169 and add comment explaining shared library screw.
2171 * source.c: #if defined => #ifdef.
2173 Thu Aug 8 12:23:19 1991 John Gilmore (gnu at cygint.cygnus.com)
2175 * doc/gdbint.texinfo: Improve doc on porting to new OS's.
2177 Tue Aug 6 17:16:15 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
2179 * doc/rdl-apps.texinfo: provide default readline-appendix finder
2180 (doc/Makefile knows how to make one for local config)
2182 * Makefile.in: use doc/Makefile for doc targets
2184 * doc/Makefile: GDB documentation now has its own Makefile
2185 doc/refcard.tex: renamed from "gdbrc.tex"
2186 doc/.Sanitize: add Makefile; recognize renamed refcard.tex
2187 doc/gdbint.texinfo: add markup in "Cleanups" chapter
2190 Fri Aug 2 00:13:06 1991 John Gilmore (gnu at cygint.cygnus.com)
2192 * values.c (baseclass_addr): When reading target memory, use the
2193 length of the basetype, not the upper type. We've only malloc'd
2194 enough space for the basetype, leading to errors in free().
2196 * expprint.c (print_subexp): Print UNOP_MEMVAL of an OP_LONG that
2197 ends up as a function specially, since we know the actual type of
2198 the pointed-to address. This (somewhat) fixes display of
2199 expressions that include misc_function_vector names. Try `cond 1
2200 !strcmp("a","b")' then `i b'.
2202 * infrun.c: Move DO_DEFERRED_STORES from proceed() to resume().
2203 The child can be proceeded from inside wait_for_inferior in
2204 evaluating breakpoint conditions, and DO_DEFERRED_STORES was
2205 getting skipped in that case.
2207 * expprint.c (print_subexp): Use filtered output, since the
2208 subroutines we call use it, otherwise the output is horribly
2209 mangled, since output of wrappable stuff comes out late.
2211 * Makefile.in: Bump VERSION to 3.98.1
2213 * infrun.c (child_create_process): Use execlp to find the
2214 shell to exec our target program. This requires some fiddling
2215 with `environ' since there is no execlpe().
2217 Thu Aug 1 15:35:17 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
2219 * Makefile.in, doc/gdbrc.tex, doc/rc-* (new files):
2220 Minor rearrangement of refcard permits two new make targets--
2221 gdbrc.dvi DVI output for refcard, using CM fonts
2222 gdbrc.ps PostScript refcard, using PS fonts
2224 Wed Jul 31 16:46:21 1991 John Gilmore (gnu at cygint.cygnus.com)
2228 * TODO, Projects, WHATS.NEW, README: Update for gdb-3.98.
2229 * Makefile.in (gdb-all.texinfo): Avoid touching file if M4 dies.
2231 Wed Jul 31 16:35:58 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
2233 * doc/gdb.texinfo: last changes for release.
2234 Minor typo and formatting fixes; incorporated most fixes remaining from
2235 filed mail commenting on earlier drafts.
2237 Added warnings: pipes don't work in run command;
2238 conditions are converse of assertions;
2239 step over fn without debug info goes to next fn;
2240 vars may have "wrong" values near fn entrance, exit
2242 Added example from Kingston on printing repeated nonadjacent values
2244 Added explicit mention that in Emacs gdb mode C-c and C-z are like
2245 shell mode for signals
2247 Renamed "Stepping and Continuing" to "Continuing and Stepping" so it
2248 doesn't sound so much like its parent "Stopping and Continuing"; also
2249 moved entries on continue to top of section, so they don't get lost.
2251 Improved installation directions in appendix, added manual formatting
2254 Tue Jul 30 17:26:39 1991 John Gilmore (gnu at cygint.cygnus.com)
2256 * configure.in: Remove xm.h and tm.h even if we aren't linking
2257 new ones, so "./configure sun4; ./configure none" does the right
2258 thing. Assume that alldeps.mak and depend are already built in
2259 srcdir, and avoid running "make" (particularly "make depend",
2260 which involves "gcc") from inside configure. Build Makefile
2261 directly rather than building Makefile.conf first.
2262 * configure: Regenerate with above changes.
2263 * Makefile.in: Use $(BISON) to find bison. Roll VERSION
2264 to 3.98. Revise gdb.tar.Z procedure to produce a file
2265 called gdb-$(VERSION).tar.Z but which unpacks into a
2266 directory called "gdb". Move non-source files out of
2267 $(SFILES_SUBDIR). Pretty up alldeps.mak with comments.
2268 (depend): Don't try to do "gcc expread.y".
2269 (expread.o): Update dependencies by hand.
2271 Mon Jul 29 15:21:09 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
2274 Fixed a variety of small typos that prevented info from formatting
2275 cleanly; altered too-long heading for GPL Appendix, as discussed
2276 w/RMS; Changed date on cover to July 91.
2278 Fri Jul 26 13:20:02 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
2281 (1) Applied some fixes due to comments from Larry Breed (easier ones
2282 through chapsec 5.2)
2283 (2) Eliminated use of @footnote---had my doubts about it anyways, and
2284 it's broken in latest texinfo
2285 (3) Introduced *some* use of [] for optional arguments, where
2286 explanation is not simpler by listing cmd w arg and cmd w/out arg
2287 separately. Still not using @deffn.
2288 (4) Dropped in GPL-2. NOTE: one of GPL-2 or texinfo is broken; a
2289 couple of headings are too long. Need patches to texinfo or revision
2292 * Partial update to README (which still needs work for this
2293 release!): (1) use of configure corrected for new script,
2294 (2) "make gdb.dvi" and "make gdb.info" mentioned.
2296 Wed Jul 24 06:44:02 1991 John Gilmore (gnu at cygint.cygnus.com)
2298 * symtab.c (lookup_symbol): Don't complain right off about
2299 no debug symbols; use the misc function vector first.
2300 (list_symbols): Use misc function vector to find symbols
2301 that don't have debug info, and print them.
2302 (find_pc_symtab): Temporarily avoid fatal() when psymtab
2303 PC range doesn't match symtab PC range, as it does on the
2304 MIPS because our symtab reading isn't perfect.
2306 * dbxread.c (dbx_symfile_read): Make warning about
2307 "no debug symbols" slightly nicer.
2309 * source.c (select_source_symtab): If "main" symbol exists,
2310 but decode_line_spec can't find line info, don't just return
2311 a zero; try other source symtabs or give an error.
2313 * mipsread.c (parse_partial_symbols): Sort the psymtabs by
2314 their low addresses first, then rip through fixing high addrs.
2316 * ns32k-opcode.h (sfsr): Bugfix from Rune Nerg}rd,
2317 <runene@ifi.uio.no>.
2318 (NS32K_SVC_IMMED_OPERANDS): Reverse the #ifndef.
2320 Tue Jul 23 18:52:43 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
2322 * Minor, mostly mechanical, cleanup of doc subdir for clean
2323 makeinfo'ing and TeXing; also ensured gdb-all.texinfo (post-m4)
2324 and gdb.info (post- texinfo2 makeinfo) generated for distribution.
2326 Sun Jul 21 03:54:52 1991 John Gilmore (gnu at cygint.cygnus.com)
2328 Mostly MIPS and general symbol-reading fixups.
2330 * doc/gdbint.texinfo: Add documentation on symbol-reading
2333 * mipsread.c: Remove kludges around #include "ecoff.h".
2334 Remove redefinitions of a_magic, etc, no longer used.
2335 (parse_symbol, ): Convert "Internal:" printfs to complain()ts.
2336 Fix global overview comments to match symfile.c protocol.
2337 (mipscoff_new_init): Eliminate cur_hdr if we have one.
2338 (mipscoff_symfile_read): Eliminate unused code. Avoid
2339 sorting all the symtabs, when all we have read here is psymtabs.
2340 The symtabs are sorted as they are created anyway. Tell
2341 condense_misc_bunches whether we're mainline.
2342 (psymtab_to_symtab_1): Pass filename when recursing, to make
2343 stack trace more informative.
2344 (parse_partial_symbols): Assume cur_hdr as argument.
2345 (read_mips_symtab): Don't clobber cur_hdr, so it can be freed.
2346 Pass cur_hdr implicitly to parse_partial_symbols. Avoid checking
2347 the TYPE_NAME of char *, since that's done in symfile.c.
2348 (free_numargs, parse_symbol, add_symbol, add_block,
2349 shrink_linetable): Declare these fns void.
2350 (upgrade_type): Convert tree of if's to switch. Clean up
2351 bogus "off == 0" handling with a complaint. Avoid setting
2352 field bitpos and bitsize of array with lower and upper bounds.
2353 Check specified bitsize of elements against their actual type's
2354 bitsize, and complain if different. Complain about unknown
2356 (parse_fdr): Don't assume sizeof(char *) == sizeof (struct *).
2357 (psymtab_to_symtab_1): Print names of subsidiary files that
2358 are being read in. FIXME, we read far too many files. This code
2359 is not the problem, the problem is in parse_fdr where the psymtabs
2361 (cross_ref): Result should indicate that we used one aux entry
2362 normally, or two if we encountered a "next" entry. This used
2363 to leave the caller pointing at the wrong aux entry.
2364 (add_symbol): If overflowed cur_block, reallocate it larger,
2365 chase all pointers to it, and complain(), rather than clobber memory.
2366 (shrink_block): Use xrealloc rather than xmalloc-and-copy.
2367 (new_field): Only allocate one field initially, not two.
2368 Pull ++ out of macro argument. Simplify.
2369 (_initialize_mipsread): Avoid initialization of importd
2370 global_psymbols and static_psymbols.
2372 * symfile.c (psymtab_to_symtab): Depend on XXX_psymtab_to_symtab
2373 to properly set pst->symtab; avoid searching for it.
2374 (symfile_fns): Improve comments, add a FIXME.
2375 * dbxread.c: Update comments to reflect symfile protocol.
2376 (read_ofile_symtab, end_symtab): Return the symtab.
2377 (psymtab_to_symtab_1): Set pst->symtab.
2379 * coffread.c (coff_symfile_read): tell condense_misc_bunches
2380 whether we're mainline.
2382 * symfile.h (sym_fns): Remove unused sym_discard member.
2383 * coffread.c, mipsread.c, dbxread.c: Remove XXX_symfile_discard.
2385 * mtrace.c (mtrace): Take effect if mallwatch is set, even if
2386 the environment variable is not.
2387 * infcmd.c (finish_command): Use filtered printfs.
2388 * cplus-dem.c: Add struct tags to a few unnamed structs.
2389 * valops.c (value_coerce_array): Improve comments.
2390 * valprint.c (type_print_varspec_suffix): Print array size only
2391 if greater than zero.
2392 * m88k-tdep.c: Shift some lines left by one space, that had
2393 apparently been trashed at some point.
2394 * TODO: More things to do, a few got done.
2396 Thu Jul 18 22:46:05 1991 John Gilmore (gnu at cygint.cygnus.com)
2398 * symtab.h (LOC_EXTERNAL): Eliminate in favor of LOC_STATIC.
2399 (ldsymoff, ldsymlen, globals_offset, statics_offset): Improve
2401 * dbxread.c (read_dbx_symtab): LOC_EXTERNAL -> LOC_STATIC.
2402 * expread.y, findvar.c, symmisc.c: Ditto.
2403 * printcmd.c (address_info): Update printed forms of LOC_
2404 symbols. Elim LOC_EXTERNAL.
2405 (print_frame_args): Keep track of param stack offsets before
2406 re-looking up to find the local register param is kept in.
2408 * mipsread.c: Use <symconst.h> and <sym.h> rather than <syms.h>.
2409 Further integration of mipsread into gdb. Eliminate unused
2410 routines, duplicate declarations. Handle static symbols in
2411 psymtabs as well as external symbols. When reading symtabs,
2412 insert symbols into the correct block (global, static, or a local
2414 (read_mips_symtab, parse_partial_symbols): Don't pass useless
2416 (mipscoff_symfile_read): Don't call select_source_symtab.
2417 (parse_symbol): Use SYMBOL_VALUE_ADDRESS where appropriate,
2418 rather than SYMBOL_VALUE.
2419 (parse_external): Comment clobbering of top_stack.
2420 (parse_partial_symbols): Update comments. Allocate and parse
2421 static symbols as well as external symbols. FIXME, enum values
2422 are not handled in this pass, but should be. Inline new_psymbol.
2423 Use SYMBOL_VALUE_ADDRESS.
2424 (psymtab_to_symtab_1): Read symbols into global static block
2425 by default (until enter some function's local block context).
2426 (sort_blocks): Clean up STATIC_BLOCK as well as GLOBAL_BLOCK.
2427 (destroy_all_symtabs, new_psymbol): Eliminate, unused.
2429 * source.c (select_source_symtab): Select a source symtab
2430 from either the symtabs or, failing that, the psymtabs.
2431 (list_command): Update error message.
2432 (forward_search_command, reverse_search_command): Use getc, not
2433 fgetc, for speed. FIXME, add comment about buffers that die if
2434 overrun by long line.
2436 * values.c (unpack_field_as_long, modify_field): Avoid shifting
2437 by an entire word, which is not portable, if we have a 32-bit
2438 field. (Code in dbxread.c already turns such bitfields, if
2439 aligned, into ordinary ints, but fixing this will help for other
2440 symbol formats and for future changes.)
2441 * core.c (core_open): Handle ANSI const brain death.
2442 * utils.c (vprintf): Fix varargs typo.
2444 Sun Jul 14 00:42:53 1991 John Gilmore (gnu at cygint.cygnus.com)
2446 * findvar.c (find_var_value): Handle &function better.
2447 * TODO: Document work needed on &fn and &array.
2448 * printcmd.c (print_address_symbolic): New arg is the prefix
2449 to print if a name is printed.
2450 (print_address_demangle): Honor "set print address" now.
2451 Use new arg above to improve spacing of output.
2452 * valprint.c (val_print): When printing function pointers,
2453 print symbolic form too.
2454 * breakpoint.c (breakpoint_1): Use new print_address_symbolic.
2456 Mon Jul 8 19:02:46 1991 John Gilmore (gnu at cygint.cygnus.com)
2458 * core.c (memory_error): Reword error msg to mislead less.
2460 * mips-pinsn.c (print_insn_arg 'd'): Print $ with reg name.
2462 * mipsread.c (read_mips_symtab, read_the_mips_symtab,
2463 parse_partial_symbols): Use newer BFD internals (external_filehdr
2464 and external_aouthdr), byte-swap the fields that we care about
2465 before using them, and make the file header data local to
2466 read_the_mips_symtab rather than global.
2468 Sat Jul 6 01:34:15 1991 John Gilmore (gnu at cygint.cygnus.com)
2470 * ns32k-opcode.h (movmw, movmd): Fix opcodes. Bug fix
2471 from Rune Nerg}rd <runene@ifi.uio.no> on 5 Jul 1991.
2473 * main.c (command_line_input): Flush stdout and stderr
2474 before every call to readline. This reportedly fixes a bug
2475 that comes up in Sys V running emacs-gdb and/or xxgdb,
2476 when stdin/out are pipes or sockets.
2478 Thu Jul 4 14:47:06 1991 John Gilmore (gnu at cygint.cygnus.com)
2480 * configure.in, Makefile.in: Avoid rebuilding "depend" as much.
2481 Avoid declaring Makefile dependencies, because GNU Make stupidly
2482 tries to update it if we do.
2484 * coffread.c: Revise for minor changes to bfd internal coff
2487 * configure: If -template= is given a relative path, make it
2488 absolute before recurring in subdirectories.
2490 * configure, configure.in, Makefile.in: Install "configure" script
2491 as replacement for config.gdb.
2492 * config.gdb, Makefile.dist, Makefile.sdir: Remove
2493 * README: Update for configure, mostly. FIXME.
2495 * Add dec3100 as equivalent to littlemips. Indicate in all host &
2496 target config files that they are for the host. When the lines
2497 get copied into the Makefile, this makes it more obvious what's
2500 Mon Jun 24 23:49:07 1991 John Gilmore (gnu at cygint.cygnus.com)
2502 * sparc-opcode.h (trap opcodes): Avoid leading spaces or
2503 tabs, which end up in the disassembler output inadvertently.
2505 Wed May 29 23:01:03 1991 John Gilmore (gnu at cygint.cygnus.com)
2507 Make it compile cleanly in an ANSI GCC2 environment.
2509 * blockframe.c: <stdio.h>
2510 * cplus-dem.c: free takes a void *, ifdef __STDC__
2511 * dbxread.c (read_huge_number): avoid gcc2 bug hoisting calc of
2513 * defs.h (alloca): Avoid doing anything if alloca already def'd.
2514 * stddef.h, stdlib.h: Remove these files.
2515 * symtab.c: Avoid declaring qsort, close.
2516 * symfile.c: Avoid declaring close.
2517 * utils.c (vprintf): Declare "ap" arg as proper va_alist.
2518 * sparc-tdep.c: Avoid including lots of Sun-host-specific files.
2520 Assorted other changes.
2521 * dbxread.c: include "libaout.h", not "liba.out.h".
2522 * printcmd.c (print_frame_args): Set recurse properly for
2523 indentation of struct and array parameters.
2524 * valops.c (value_cast): Allow cast to void.
2525 * infrun.c (resume): If NO_SINGLE_STEP, call machine dependent
2526 single_step() in a target-independent fashion.
2527 * sparc-tdep.c (single_step): Don't call ptrace ourselves, just
2528 set up to be ready to continue. This makes us target independent.
2529 * infptrace.c (child_resume): Remove call to single_step; now
2530 can single step a SPARC target of any kind.
2532 Wed May 22 18:18:24 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
2534 * Makefile.dist, doc/gdb.texinfo, doc/*-m4.texinfo: split up GDB
2535 docn into separate sections---basically chapters, plus two loose
2536 pieces that can be configured to go in different places. This
2537 allows GNU m4 to preprocess the manual without coredumping.
2539 * Makefile.dist: tell TeX where to find texinfo.
2541 Mon May 20 12:15:04 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
2543 * Makefile.dist, doc/gdb.texinfo: respectively create, and use,
2544 the new target "rdl-apps.texinfo" which captures the Makefile
2545 variable that records where to find the Readline libraries.
2547 Sun May 19 05:36:59 1991 John Gilmore (gnu at cygint.cygnus.com)
2549 * tahoe-pinsn.c: #include "tahoe-opcode.h", not "opcode.h".
2550 * tm-tahoe.h (FIX_CALL_DUMMY): Ignore more parameters.
2551 * defs.h (const, volatile): Only define if not already defined.
2552 * Makefile.dist (gdb.tar.Z): Create doc subdir w/out CVS/RCS crud.
2554 * README: Update for release 3.95.
2555 * config.gdb: Don't create readline dir in subdir builds.
2556 * main.c: Include with "..." form for non-system include files,
2557 so "gcc -MM" for "make depend" works.
2558 Include readline files with "...h" rather than <readline/...h>.
2559 * mipsread.c: Include "ecoff.h" rather than "intel-coff.h".
2561 * coffread.c: Undo minor damage done by Rich Pixley. Use
2562 different internal and external representations of COFF
2563 data structures. Use new BFD routines for swapping them in and
2565 * symfile.c (free_named_symtabs): Avoid freeing file names that
2566 are null or empty. Old i960 tools seem to produce files that
2567 claim to have empty names, causing each successive file read
2568 to blow away the previous one.
2569 * sparc-xdep.c (deferred_stores): Repair minor damage by Rich.
2570 Move deferred_stores to top of file, but don't separate its
2571 #define's from its variable. Add commentary.
2572 * Makefile.dist: Fix Rich damage; undo "configure" changes in
2573 favor of keeping the (working) config.gdb. Move readline
2576 Fri May 17 12:49:56 1991 Per Bothner (via gnu at cygint.cygnus.com)
2578 * dbxread.c (read_struct_type): Try to handle g++ version 1 MI
2580 * infptrace.c (fetch_registers): no result, since now void.
2581 * tconfig/news: target depends on m68k-tdep too.
2583 Fri May 17 14:40:14 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
2585 * Makefile.dist: added readline/inc-*.texinfo to dependencies for
2588 * readline/inc-history.texinfo, readline/inc-readline.texinfo:
2589 applied various small fixes due to or inspired by RMS comments
2591 * doc/gdb.texinfo: finished using all RMS comments, save those for
2592 appendices on readline and cmd history (which are in other source
2595 Thu May 16 18:06:05 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
2597 * doc/gdb.texinfo: (1) Updated w/ref to RMS comments through
2598 chapter 9; (2) documented 'break' command's menu mode for
2599 overloaded names, in response to hgs problem report C++ p-31
2601 Wed May 15 11:02:48 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
2603 * doc/gdb.texinfo: (1) better introductory example; (2) more
2604 consistent use of @code, @samp, @file, @kbd throughout; small
2605 cleanups to first three nodes; (3) new "Contributors" node;
2606 (4) Appendix, Renamed Commands; (5) divert specialized startup
2607 instructions to "Targets" chapter for generic manuals, while
2608 leaving them up front for manuals specific to specialized
2609 environments; (6) apply fixes from RMS comments through chapter 4.
2611 * pretex.m4: modify explanatory text slightly (and redefine
2612 "regexp") to keep GNU m4 from complaining. (It still crashes
2613 later, but one step at a time...)
2615 Wed May 15 10:32:12 1991 John Gilmore (gnu at cygint.cygnus.com)
2617 * readline/readline.c (update_line): Avoid dereferencing a pointer
2618 before comparing it to its bounds. Saber caught this.
2619 (init_terminal_io): Don't set BC from the "pc=" termcap variable,
2620 and only set PC if tgetstr returned non-null. Saber caught this.
2622 Tue May 14 16:29:53 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)
2624 * Makefile.dist: put gdb.dvi stuff (updated to use M4 preprocessor
2625 stuff for config manual) here where it counts; updated
2626 to use new subdir structure (gdb/doc/).
2628 * Makefile: generated from above via
2632 * gdbint.texinfo: added instructions on generating gdb.info* files
2633 locally for release. These are ordinary info
2634 files, formatted from gdb.texinfo (via gdb-all.texinfo, see
2635 Makefile)---but due to use of texinfo 2, can't count on makeinfo
2636 to generate these, so we distribute them already formatted.
2638 * gdb.texinfo: included full Info node and menu crud (as generated
2639 by C-u M-x texinfo-master-menu using the texinfo-2 elisp code).
2641 * Makefile: updated "gdb.dvi" target to use M4 preprocessor;
2642 put in comments-for-future gdb.info target (one day makeinfo will
2645 Tue May 14 13:51:36 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)
2647 * gdb.texinfo: Updated to include new or old undocumented
2648 commands, at least the following (perhaps some others I forgot to
2649 record): info f, info float, info path, info program, info s, info
2650 set, info source, info terminal, info types, info user, set/show
2652 Also covered all recent GDB command renames for v4.
2654 Mon May 13 14:57:46 1991 John Gilmore (gnu at cygint.cygnus.com)
2656 * mipsread.c: Rather than keeping count of how many symtabs
2657 and psymtabs we have, for sorting purposes, count them when
2658 we need to sort. This fixes bug in rereading of symbol tables.
2660 Fri May 10 15:43:33 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)
2662 * infcmd.c: renamed "info path" to "show paths"

2676 * coffread.c, exec.c, infptrace.c, inftarg.c, remote.c, solib.c,
2677 symtab.h, target.c, target.h: Lint.
2678 * core.c: setup and select frame after reading shared libs,
2679 else reading shared libs will clobber them. Lint.
2680 * utils.c (error): Force out any buffered wrap text.
2682 Fri May 3 22:01:56 1991 John Gilmore (gnu at cygint.cygnus.com)
2684 * remote.c: Remove decls of memory_insert_breakpoint
2685 and memory_remove_breakpoint, no longer used. (Suggestion of
2688 * Makefile.dist: use ${subdir} in paths of BFD and LIBIBERTY,
2689 to make it easier to interface to "configure"'d libraries.
2691 Fri May 3 13:10:01 PDT 1991 Roland Pesch (pesch at fowanton.cygnus.com)
2693 * valprint.c: introduce "set p", "set pr", "show p" and "show pr" as
2694 aliases for set/show print.

2750 * coffread.c [TDESC]: Move setting of debug_info from
2751 coff_symfile_read to find_linenos and make it work with BFD.
2753 * cplus-dem.c [__STDC__]: Make x{m,re}alloc return void*.
2755 * signame.c: Cast const char* to char* when assigning to sys_siglist.
2757 * utils.c (strsave): Make arg const char* not char*.
2759 * infrun.c (wait_for_inferior) [SHIFT_INSN_REGS]: Use

2780 Mips bringup and general cleanup
2782 * cplus-dem.c: Move CPLUS_MARKER define to after defs.h.
2783 * infptrace.c (PT_WRITE_D, PT_READ_D): Use correct values.
2784 (This still doesn't seem to make MIPS bkpts work.)
2785 * mipsread.c: Remove dup "Reading symbol data..." msg.
2786 (symbol_file_command, add_file_command): Remove, obsol.
2787 * printcmd.c (ptype_command): Say "an enum" rather than "a enum".
2788 Wrap output appropriately.
2789 * stack.c (locals_info, catch_info, args_info): Check
2790 selected_frame rather than target_has_stack or coredumping.
2791 * valprint.c (type_print_varspec_suffix): Wrap "ptype" output of
2792 enums appropriately.
2794 Wed May 1 14:10:22 1991 Jim Kingdon (kingdon at cygint.cygnus.com)

2798 * cplus-dem.c: Include defs.h and param.h.
2799 Makefile.dist: Don't hack in the "param.h".

2803 can have both ints and enum type_pieces in it.
2804 ({push,pop}_type_int): New functions.
2806 Tue Apr 30 13:18:58 1991 Jim Kingdon (kingdon at cygint.cygnus.com)

2818 symtab.c, cplus-dem.c, value.h, expread.y, valprint.c,
2819 copying.awk, solib.c, inflow.c, symmisc.c
2820 : Lint. Use read_memory not read_memory_integer on CORE_ADDR's.
2821 Use {value_as,unpack}_pointer (added to values.c)
2822 not {value_as,unpack}_long on CORE_ADDR's.
2823 Use longest_to_int (added to defs.h) instead of cast to int.
2824 Remove from_tty arg to mod_path.
2825 Put symfile_bfd in {coff,dbx}read.c not symfile.h.
2826 Use OP_NULL instead of 0 where dummy enum exp_opcode needed.

2867 Sun Apr 28 22:04:47 1991 Jim Kingdon (kingdon at cygint.cygnus.com)
2869 * param-no-tm.h: Make BITS_BIG_ENDIAN defined to 0/1, not defined
2870 or not defined. Don't define it based on TARGET_BYTE_ORDER if

2872 mips-opcode.h (BIT_FIELDS_*),
2873 values.c (modify_field, unpack_field_as_long):
2874 Use #if BITS_BIG_ENDIAN not #ifdef BITS_BIG_ENDIAN.
2875 {x,t}m-tahoe.h, tahoe-pinsn.c, tahoe-opcode.h: New files.
2877 Fri Apr 26 12:02:06 1991 Jim Kingdon (kingdon at cygint.cygnus.com)
2879 * tm-sparc.h: Add comments about gcc version 2 and structure passing.
2881 * xconfig/i386v{,32}{,-g}: Add XM_CFLAGS=-Dgetpagesize()=4096.
2882 gmalloc.c: #if 0 out !HAVE_GETPAGESIZE code.
2884 * expread.y (abs_decl): Accept '&' and '&' abs_decl.

2887 regardless of LONG_LONG.
2888 defs.h (TARGET_LONG_LONG_BIT): New macro.
2889 expread.y (typebase): Add {unsigned,} long long {,int}.

3299 (set_section_command): New command ("section xxx yyy" -- should
3300 be renamed to "set section xxx yyy" FIXME) which sets the

3314 * i386-pinsn.c: Move #includes to top, remove useless ones.
3315 * i386-tdep.c: Don't bother including <.../reg.h> since we

3362 * dbxread.c (really_free_pendings): Clear file_symbols
3363 and global_symbols after freeing them; otherwise, running
3364 this function twice (if it appears twice on the cleanup
3365 chain), we try to free things twice.
3367 * dbxread.c (read_dbx_symtab): Calculate end_of_text_addr
3368 based on text_addr (the address of text in core), not on addr (the
3369 offset between text in the .o file and in core). This change
3370 is from Peter Schauer.
3372 * main.c: Define ALL_CLEANUPS as a cast of zero.
3373 (return_to_top_level): Use it.
3374 (main): Do all cleanups after each command run as part
3375 of the gdb startup sequence. Also do all cleanups before
3376 entering the command loop, and every time we exit the command
3377 loop and reenter. Before, the cleanups from the startup sequence
3378 were being left undone until the first error!
3379 (command_loop): Rename do_nothing cleanup to command_loop_marker
3380 so we can see it easily when examining the cleanup chain.
3381 (init_signals): Add another do_nothing for signal handling.
3382 (quit_command): Only try to kill target if it has execution.
3383 Problems in the target stack got us into a state where
3384 inferior_pid was nonzero but none of the targets had execution.
3385 In this state you couldn't exit gdb.
3387 * dbxread.c: Two changes from Peter Schauer.
3388 (echo_command): Fflush output after an echo command.
3389 (show_history): Pass all args to cmd_show_list.
3391 * utils.c (init_malloc): Call mtrace to turn on tracing
3392 if the environment variable MALLOC_TRACE is set to a file name.
3393 * mtrace.c: Add source file which provides a log of every malloc,
3394 free, and realloc to a trace file.
3395 * mtrace.awk: Add source file which analyzes the trace file.
3396 * Makefile.dist (GNU_MALLOC, MALLOCSRC): Add mtrace.{c,o,awk}.
3397 (VERSION): Roll to 3.94.3.
3399 * breakpoint.c (breakpoint_1): Add a space to "i watch" output.
3400 (check_duplicates): Don't bother with watchpoints.
3401 (set_raw_breakpoint): Comment about danger of this routine.
3402 (watch_command): Parse and eval all args before calling
3405 * solib.c (find_solib): Avoid error in referencing memory to
3406 see if any more shared libraries have been added. This is
3407 particularly useful if the target has terminated. Bug reported
3410 Changes from Peter Schauer <pesrem@regent.e-technik.tu-muenchen.de>
3411 in bringing up 3.94.2 on the Sun-3.
3413 * Makefile.dist: Include CFLAGS in rule for cplus-dem.o.
3414 * breakpoint.c (enable_breakpoint): Check for valid watchpoint
3415 expression (in scope) before reenabling watchpoint.
3416 * signame.c (init_sigs): Add missing declaration of i, fix
3417 sys_siglist declaration.
3418 * source.c (list_command): Fixed range computation to use
3420 * stack.c (backtrace_command): Do not allow command if target has
3421 no stack, print informative error message.
3422 * target.c (target_command): Do not write into command line
3423 because this fails if the target command is used in a user defined
3424 command. [This change was enhanced by gnu to support any-
3425 unique-prefix matching on target names.]
3426 * valops.c (value_struct_elt): Avoid infinite loop on an
3427 erroneous attempt to print the member of function (try p main.p).
3429 Mon Apr 1 17:05:45 1991 John Gilmore (gnu at cygint.cygnus.com)
3431 * expread.y (name_no_typename): Avoid reduce/reduce errors
3432 caused by ambiguity in handling NAME_OR_INT and NAME_OR_UINT.
3433 Since the GDB parser really doesn't use name_no_typename in a
3434 name-only context, the parser can't tell the diff between
3435 names and numbers here. Avoid allowing a name_no_typename
3436 to be a NAME_OR_*INT to resolve the conflict.
3438 Sun Mar 31 20:12:07 1991 John Gilmore (gnu at cygint.cygnus.com)
3440 Bugfixes from Mark Fox (markf@wrs.com) (test=testField.c):
3442 * valprint.c (val_print_fields): bitfield printing didn't handle
3443 byte order. Indirect through a few more fns to cope.
3445 * values.c (modify_field): also cope with byte order.
3447 Sat Mar 23 10:02:21 1991 John Gilmore (gnu at cygint.cygnus.com)
3449 Cleanup for release 3.94.2:
3451 * Makefile.dist: Pull REMOTE_OBS. Fix saber includes for BFD
3452 include files. Roll version to 3.94.2.
3454 * coffread.c (init_stringtab): Read length into unsigned char
3455 array before swapping; don't assume 32-bit longs.
3457 * target.c (target_info): Don't bother with get_sym_file, just use
3458 the symfile global variable.
3459 * symtab.h, symfile.c (get_sym_file): Delete it.
3461 * dbxread.c (dbx_symfile_init): Don't depend on long == 4 bytes.
3462 (define_symbol): Set symbol line number to 0 if not gcc-compiled.
3463 (read_type): Replace one more error() with complain().
3465 * mipsread.c (parse_partial_symbols): Replace printf with complain.
3467 * i960-tdep.c: Fix copyright attribution.
3469 * config.gdb: Quote all backquotes in doublequotes. You can
3470 quote me on that. BSD 4.4 shell found this one.
3472 * infptrace.c (throughout): The third argument to ptrace is an
3475 * infrun.c (wait_for_inferior): When program has terminated, we
3476 have to call target_terminal_ours before we pop that target off
3477 the stack (e.g. before a call to target_kill or
3478 target_mourn_inferior). This fixes problem where a program
3479 terminates, then GDB stops for (tty output) and you have to type
3480 "fg" to the shell to resume it. FIXME: This code for what to
3481 do after termination really should be in normal_stop instead.
3483 * gdbcore.h (read_memory_check): Change declaration; it changed
3486 * terminal.h: Include <sgtty.h> before <sys/ioctl.h>, since in BSD
3487 4.4 prereleases, this avoids a bug in their sgtty compatability
3489 * remote.c: Use terminal.h rather than hand-rolling the same.
3491 * signame.c, signame.h (psignal): Arg is unsigned, not int.
3492 * utils.c (strsave, strstr): Fix arg types.
3493 * valprint.c (val_print): lint
3495 MIPS symbol table support from Per Bothner:
3497 * symfile.c (symtab_fns): Remove initializer table that needs to
3498 be hacked for each new symbol file format supported.
3499 (add_symtab_fns): New function, chains symbol table
3500 handlers into the global list.
3501 (symfile_init): Search this list.
3502 * symfile.h: Add next pointer, declare add_symtab_fns.
3503 * coffread.c (_initialize_coffread): Call add_symtab_fns.
3504 * dbxread.c (_initialize_dbxread): Call add_symtab_fns.
3506 * mipsread.c (psymtab_to_symtab_1): return void instead of (struct
3507 symbol *). Thus, we no longer need the hack to trash
3508 pst->filename. Good, since that hack confused code in symfile.c!
3510 (reorder_symtabs, destroy_all_symtabs): Removed static
3511 all_symtabs, which was used to qsort symtabs in reorder_symtabs.
3512 Instead, the latter now uses a temporary array (stack-allocated
3513 from an obstack, and then freed).
3515 (parse_symbol): Added a hack to fix up BLOCK_{START,END} if they
3516 haven't been set in the outermost stBlock of a procedure. This was
3517 a problem with f77 binaries on Ultrix 4.?.
3519 (new_symtab, new_symbol, new_type): Continue changing code to use
3520 obstacks more and otherwise conform to dbxread internal style.
3521 Made the free_code of symtabs be free_linetable (as in dbxread)
3522 instead of free_contents. This implies memory leaks when reading
3523 a new symbol table, until the conversion is finished. Did change
3524 (struct symbol) and (struct type) to be allocated on the
3525 symbol_obstack. Blocks and blockvectors are among the things
3528 * mipsread.c (parse_partial_symbols, parse_fdr): It hasn't been
3529 tested much, but it solved one problem (reported by Meissner), and
3530 cleans up some other things. The problem happened when an
3531 included file contains actual code (functions) and not just
3532 definitions. The mips coff is a little inconvenient there, since
3533 it may cause a procedure to be mapped to the wrong psymtab.
3535 * mips-tdep.c (heuristic_proc_desc): Minor cleanup.
3536 * mips-xdep.c (fetch_core_registers): Minor cleanup. FIXME,
3537 this will need work for the new core paradigm.
3539 Opcode patches from the net:
3541 * mips-opcode.h: fix incorrect disassembly of the mfc1, cfc1, and
3542 ctc1 instructions. Also, the cvt.d.w and cvt.s.w instructions were
3543 missing altogether - they are added here. From Bruce Bauman.
3544 * mips-opcode.h: The low mask for C0 instructions was too small.
3545 From Garrett Lau. I modified the fix to check the entire 32-bit
3548 * ns32k-opcode.h: Fix opcodes for deiw and deid. From Bruce
3551 Thu Mar 21 12:56:46 1991 John Gilmore (gnu at cygint.cygnus.com)
3553 Roll in changes from Per Bothner (Tue, 25 Sep 90 11:11:04):
3555 * dbxread.c (read_type): Pointer subtraction (value_sub in
3556 valarith.c) sometimes failed because the types of the
3557 pointers being subtracted were not identical.
3558 These differed because dbxread.c was allocating pointer types
3559 using dbx_alloc_type+smash_to_pointer_type instead of
3560 lookup_pointer_type. I failed to find a justification for the
3561 former, so I changed it to use the latter. Similarly, I
3562 replaced smash_to_function_type by lookup_function_type,
3563 and smash_to_reference_type by lookup_reference_type.
3565 * mipsread.c (parse_symbol, upgrade_type, parse_procedure,
3566 _initialize_mipsread): corresponding changes.
3568 * symtab.c (smash_to_{pointer,reference,function}_type): eliminate.
3570 * source.c (mod_path): Do tilde_expand on each component of the path,
3571 rather than on the (list of) paths as a whole.
3572 (print_source_lines): Set first_line_listed in addition to
3573 current_source_symtab and current_source_line. If the source was
3574 not findable, after a "dir" command to fix the problem,
3575 a "list" would get the wrong lines.
3577 While I was there... (gnu):
3579 * dbxread.c (read_type): Change error to complaint.
3581 Thu Mar 21 12:56:46 1991 John Gilmore (gnu at cygint.cygnus.com)
3583 First attempt at detailed understanding of symbol table memory alloc.
3585 * dbxread.c (dbx_symfile_read): Free our string table if we
3586 aren't the mainline. Free the "info" struct since we're done with
3588 (init_psymbol_list): Free any previously allocated psymbol lists.
3589 (): FIXME: Should realloc-down the psymbol lists when done reading
3590 the main symbol file?
3592 * symmisc.c (free_symtab): Free fullname field too.
3594 * xm-hp300hpux.h (USG): #undef then #define so Makefile can -D.
3595 (REGISTER_ADDR): Make result type unsigned int.
3597 * xconfig/{i386*,hp300hpux,altosgas,altos}: All config files that
3598 define REGEX must also define REGEX1 (its dependency).
3600 Tue Mar 19 21:28:57 1991 John Gilmore (gnu at cygint.cygnus.com)
3602 * tconfig/i960: No longer works, points you at vxworks960 or
3605 * xgdb.c, XGDB-README: Remove file. Users can get the much
3607 * Makefile.dist: Remove all trace of xgdb.
3609 * breakpoint.c (breakpoint_1): Pass demangle arg to
3610 print_address_symbolic.
3611 (clear_breakpoints): Remove unused function.
3612 (breakpoint_re_set_one): Guts of breakpoint_re_set.
3613 (breakpoint_re_set): Use catch_errors to do them all anyway.
3615 * gdb-int.texinfo (Host versus Target): Add section on what is
3616 a "host" feature versus what is a "target" feature.
3618 * infcmd.c (path_command, path_info): Handle the PATH variable
3619 (object search path) as conveniently as the source search path.
3620 * environ.c (set_in_environ): Set some vars in GDB's environment,
3621 in addition to the child's. PATH, G960BASE, G960BIN for starters.
3622 * source.c (mod_path): New function, from guts of
3623 directory_command, modifies a path. Used by path_command.
3624 (directory_command): Call it.
3625 * defs.h (strsave): Declare.
3627 * utils.c (sevenbit_strings): Add new printing option.
3628 (printchar): Use it.
3629 (strsave): Provide this handy helper routine.
3630 (set_width_command): Rename set_screen_width_command.
3631 (_initialize_utils): "set screen-width" => "set width";
3632 "set screen-height" => "set height"; add sevenbit-strings.
3634 * infcmd.c (do_registers_info): Print floating point registers
3635 in raw hex as well as float format, regardless of whether it is
3636 a "virtual" convertible register.
3637 * tm-sparc.h (PRINT_REGISTER_HOOK): Print every pair of float
3638 regs as a double, just in case it's being used that way.
3639 * values.c (unpack_long): Comment on array/function coercion.
3640 (unpack_double): Argument is in target byte order now. For
3641 integer arguments, just call unpack_long and float the result.
3642 * m68k-tdep.c: include defs.h for "const" handling.
3643 * remote-nindy.c: Use ieee-float stuff.
3644 (nindy_fetch_registers): Unpack double regs to host double, then
3646 (nindy_store_registers): Pack extendeds to host double, flip
3647 around by misusing unpack_double, send as target double.
3649 * tm-vxworks68.h (FRAME_CHAIN): Handle current frame pointer of
3650 zero, as when stopped at the first instruction of a process.
3652 * blockframe.c: Fix filename in comment (param.h => tm.h).
3653 * sparc-tdep.c (skip_prologue): More explicit nudging comments.
3654 * tm-68k.h: Fix typos.
3656 Fri Mar 15 01:09:34 1991 John Gilmore (gnu at cygint.cygnus.com)
3658 Changes from a bringup on the DEC Vax under Ultrix 4.0.
3660 * coredep.c (fetch_core_registers): Pass end-address of register
3661 section to register_addr as expected. Don't call supply_register
3662 if we'd just pass it garbage.
3664 * dbxread.c (read_dbx_symtab): Skip N_NSYMS on Ultrix.
3666 * exec.c (xfer_memory): Use boolean xfer_fn result, not int.
3668 * target.c (push_target, target_info): Cast enums to int for < or
3671 * stack.c (print_frame_info): Identify source file & line
3672 even if we can't print it.
3674 * xm-vax.h (MISSING_VPRINTF): No longer missing in Ultrix V4.0.
3676 Sat Mar 9 10:08:20 1991 John Gilmore (gnu at cygint.cygnus.com)
3678 Clean up IEEE floating point support.
3680 * ieee-float.h: New file.
3681 * ieee-float.c: Write real routines to convert between host
3682 doubles and various target IEEE extendeds.
3683 * m68k-xdep.c: Eliminate assembler code for extended floats.
3684 * xconfig/{3b1,altos,altosgas,hp300bsd,isi,news,news1000,sun2os3,
3685 sun2os4,sun3,sun3os3,sun3os4}: Eliminate use of m68k-xdep.o.
3686 * tm-i960.h, tm-68k.h (REGISTER_CONVERT_TO_VIRTUAL,
3687 REGISTER_CONVERT_TO_RAW): Use ieee_extended_to_double and
3688 double_to_ieee_extended.
3689 * i960-tdep.c: Define ext_format_i960.
3690 * m68k-tdep.c: Define ext_format_68881.
3691 * sparc-tdep.c: Define ext_format_sparc, though unused.
3692 * Makefile.dist (HFILES): Add ieee-float.h.
3693 * inftarg.c: #include "ieee-float.h" for the REGISTER_CONVERT
3696 Obsolete the "coffstrip" program in favor of using BFD's strip.
3698 * nindy-share/coffstrip.c: Remove file.
3699 * nindy-share/nindy.c (coffstrip): Routine to run bfd_strip.
3700 * Makefile.dist: Remove references to nindy-share/coffstrip.c.
3701 * tconfig/nindy960: Remove reference to coffstrip.o.
3703 * Makefile.dist: Roll version number to 3.94.1 (not yet final).
3705 Wed Mar 6 09:56:45 1991 John Gilmore (gnu at cygint.cygnus.com)
3707 * symfile.h: Add symfile_bfd, common between dbxread and coffread.
3708 * dbxread.c: Remove static symfile_bfd.
3709 * infcmd.c (do_registers_info): Add PRINT_REGISTER_HOOK, though
3711 * inftarg.c (child_detach): Pop the child_ops vector if the
3712 detach is successful.
3713 * remote-nindy.c (nindy_create_inferior): Don't push a new
3714 nindy_ops since nindy uses the same one for execution and memory
3716 * core.c (core_ops): Use child_attach and child_create_inferior
3717 rather than default attach and create_inferior functions.
3719 Handle floating point registers in core files.
3721 * sparc-xdep.c (fetch_core_registers): Rewrite for float support.
3722 * sun3-xdep.c (fetch_core_registers): Rewrite for float support.
3723 This version untested since BFD doesn't yet support sun3 core
3725 * hp300hpux-xdep.c: Rewrite fetch_core_registers to new calling
3726 conventions. Fix comments and style. This version has not
3727 been compiled yet, since we have no HP inhouse.
3728 * core.c (get_core_registers): Look for two sections, ".reg"
3729 and ".reg2", and pass both to fetch_core_registers sequentially.
3731 Revise directory path yet again.
3733 * source.c (forget_cached_source_info): Not static any more.
3734 (init_source_path): New default source path is "$cdir:$cwd".
3735 (dir_command): Handle variable arguments ($cdir, $cwd).
3736 (source_info): Print "Compilation directory" rather than
3737 "Originally compiled in" to remind people of $cdir.
3738 (openp): If the path contains $cwd, use current directory.
3739 (open_source_file): If compilation directory is known, replace
3740 first $cdir in path with the compilation directory.
3741 (print_source_lines): Even if we can't print the lines, set the
3742 current symtab and line for future commands like "info source" or
3743 "breakpoint". Also, error message now contains the file name,
3744 line number, and file access error message.
3745 (_initialize_source): Fix help text to describe changes.
3746 * main.c (cd_command): Forget cached source info when we chdir.
3747 * utils.c (strstr): Add simple implementation.
3749 Tue Mar 5 01:41:40 1991 John Gilmore (gnu at fowanton.cygnus.com)
3751 * coffread.c (read_one_sym, init_linetable, init_stringtab):
3752 Byte-swap COFF symbol tables if necessary when reading them in.
3753 Use complain() to replace error message in one spot. Needs
3754 corresponding change in bfd/coff-code.h to make some symbol
3755 swapping routines non-static.
3757 Mon Mar 4 00:53:40 1991 John Gilmore (gnu at cygint.cygnus.com)
3759 Merge changes from Eirik Fuller, for UTek.
3761 * defs.h (errno): Add declaration.
3762 * altos-xdep.c, arm-xdep.c, convex-xdep.c, gould-xdep.c,
3763 hp300hpux-xdep.c, infrun.c, inflow.c, infptrace.c, i386-tdep.c,
3764 i386-xdep.c, pyr-xdep.c, mips-xdep.c, remote-eb.c, remote-nindy.c,
3765 remote-vx.c, source.c, standalone.c, stuff.c, sun386-xdep.c,
3766 symmetry-tdep.c, symmetry-xdep.c, umax-xdep.c, utils.c: Eliminate
3767 declarations of errno.
3769 * remote-eb.c: Define B19200 and B38400 as EXTA and EXTB.
3771 * remote-vx.c: Include <sys/time.h> for UTek; Sun gets it via
3772 <rpc/rpc.h> and <rpc/types.h>.
3774 Sat Mar 2 15:47:55 1991 John Gilmore (gnu at cygint.cygnus.com)
3776 * i960-tdep.c (examine_prologue): Add new argument limit,
3777 which stops the scan at the end of the prologue, or at the PC.
3778 This fixes a problem where it walks down into the code for the
3779 user's statements if that code looks like function prologues.
3780 Mark Fox and I have been bouncing this code back and forth, making
3781 small changes to it. Callers changed to match.
3783 Tue Feb 26 01:47:07 1991 Cygnus John Gilmore (cygnus at yuba)
3785 Cleanup for gdb-3.94 release final:
3787 * Makefile.dist: Remove remote-vx.c, remote-nindy.c, and all
3788 the .c files from vx-share and nindy-share, from the various
3789 macros, since they are not found via ALLDEPFILES.
3790 (SFILES): Add tm-i960.h.
3791 (alldeps.mak rule): Break out ALLDEPFILES_MAINDIR and
3792 ALLDEPFILES_SUBDIR. List all the nindy and vxworks subdir files
3794 (TAGFILES_MAINDIR): Change ALLDEPFILES to ALLDEPFILES_MAINDIR.
3795 (gdb.tar.Z): Use ALLDEPFILES_SUBDIR as well as SFILES_SUBDIR.
3797 Mon Feb 25 16:02:35 1991 Cygnus John Gilmore (cygnus at oldman)
3799 * am29k-tdep.c: Add contribution line.
3800 (examine_prologue): Cache information about function prologues in
3801 the misc-function-vector to avoid lots of references over the
3802 serial line while examining instructions.
3804 * core.c (core_close): New function made from cleanup_core.
3806 * core.c, exec.c, inftarg.c, remote-eb.c, remote-nindy.c,
3807 remote-vx.c, remote.c, target.c, target.h,
3808 Update target_ops vector to add attach, close, and load entries.
3809 Use add_syms_addr_command, not add_file_addr_command, for
3810 add_file. Break out close routine from existing code.
3812 * dbxread.c (really_free_pendings): Don't free pending_blocks;
3813 they are in an obstack.
3814 (read_dbx_symtab): Relocate end_of_text_addr in the psymtab.
3816 (define_symbol): Add symbol type parameter; change callers;
3817 pass type parameter to DBX_PARM_SYMBOL_CLASS macro to allow
3818 it to influence the symbol class on the i960.
3819 (define_symbol): Swap LOC_CONST's into target byte order.
3821 * exec.c (exec_close): New function.
3822 (exec_file_command): Call it.
3824 * findvar.c (read_relative_register_raw_bytes): Doc byte order,
3825 Fix byte order of frame pointer.
3826 (read_var_value): Result of 0 if var's value can't be found,
3827 e.g. missing FRAME_ARGS_ADDRESS. Byte-swap LOC_CONST and
3828 LOC_LABEL values to target order. Add LOC_LOCAL_ARG.
3829 (locate_var_value): Use read_var_value and use its lazy address
3830 as the location of the var's value. Lint.
3832 * i960-pinsn.c (next_insn): Add routine from vxgdb for scanning
3835 * i960-tdep.c (arg_address, i960_frame_find_saved_regs): Remove
3836 obsolete Intel versions in favor of vxgdb versions.
3837 (check_host, byteswap, byteswap_val, reorder_val): Eliminate
3838 code dealing with byte order of values, which Intel did in host byte
3839 order rather than gdb-4's target byte order.
3840 (i960_frame_chain_valid): Move to nindy-tdep.c.
3841 (examine_prologue, skip_prologue, frame_find_saved_regs,
3842 frame_args_address, leafproc_return, saved_pc_after_call,
3843 pop_frame): Add vxgdb versions from Mark Fox.
3844 (examine_prologue, frame_struct_result_address): Add code
3845 to deal with the saved value of G13 (struct return address
3847 (frame_args_address): Modify Mark's version to prefer the
3848 saved value over the current value in the topmost frame.
3849 Cache result in the frame info to avoid performance hair in
3851 (print_fault): Add gdb960 code for printing faults.
3852 (_initialize_i960): Actually call check_host.
3854 * ieee-float.c (ieee_extended_to_double, ieee_double_to_extended):
3855 add stub routines. FIXME, these currently just return zero!
3857 * infcmd.c (program_info): Use PRINT_RANDOM_SIGNAL.
3858 (attach_command): Call target_attach, not target_open, now.
3860 * infrun.c (normal_stop): Make global, not static, for vx_attach.
3861 (child_attach): Rename from child_open.
3862 (wait_for_inferior): Use PRINT_RANDOM_SIGNAL. If stop_pc is zero,
3863 don't confuse it with a zero step_resume_break_address.
3865 * inftarg.c (child_detach): Eliminate inferior_pid test.
3866 (child_files_info): Clean up message a bit.
3867 (child_ops): Use child_attach, not child_open, to attach.
3869 * mem-break.c: #ifdef out the whole file if BREAKPOINT is not
3870 set (e.g. on VxWorks or NINDY). Move read_memory_nobpt from
3871 findvar.c to here, since it depends on the contents of the
3872 shadow_contents of breakpoints, but keep if #if 0 since it is
3875 * nindy-tdep.c: New file, contains nindy_frame_chain_valid, moved
3878 * printcmd.c (address_info): Handle LOC_LOCAL_ARG. Lint.
3879 (ptype_command, display_command): Eliminate have_inferior_p and
3880 have_core_file_p in favor of target_has_stack or
3881 target_has_execution.
3882 (print_frame_args): Handle LOC_LOCAL_ARG. Eliminate duplicate
3883 code for actually finding the values of arguments, though we still
3884 keep track of the maximum stack offset for use in printing unnamed
3885 arguments. Handle missing FRAME_ARGS_ADDRESS.
3887 * remote-nindy.c (i960_print_fault): Move to i960-tdep.c.
3888 (struct nindy_regs): Define registers passed to/from nindy.
3889 (nindy_fetch_registers, nindy_store-registers): Translate between
3890 nindy and GDB formats for the registers.
3891 (dcache_init): Statically allocate the cache, since it was being
3892 allocated by a malloc that was never freed anyway.
3893 (nindy_create_inferior): Error, not core dump, if no exec file.
3894 (nindy_before_main_loop): Use target_load, not target_add_file.
3896 * remote-vx.c (net_load): Specify large timeout for load
3897 requests. Allow user to break out with INTERRUPT.
3898 (net_break): Remove useless code, clean up. Change callers.
3899 (parse-args, skip_white_space, find_white_space): Clean up arg
3900 parsing to cope with quoted strings.
3901 (net_wait, net_quit): Never call error, just return status.
3902 (vx_read_register, vx_write_register): Cleanup status checking.
3903 #ifdef the code based on which CPU we are using (960 or 68k),
3904 FIXME, this should be completely general but it isn't yet.
3905 (vx_xfer_memory, vx_resume): Cleanup status checking.
3906 (vx_run_files_info): Improve message.
3907 (vx_load_command): Renamed from vx_add_file_command. Allow load
3909 (net_ptrace): Remove unused routine.
3910 (vx_wait): Adopt code from vxgdb960 to cope with broken
3911 connections to target machine and prompt to disconnect. Remove
3912 debug printouts. Map some EVENT_'s to SIGnals.
3913 (add_symbol_stub, vx_open): Print names of object files we found,
3914 and "ok" if we read their symbols OK. Clarify output in general.
3915 (vx_attach, vx_detach, vx_kill): Add these commands.
3916 (vx_convert_from_virtual, vx_convert_to_virtual): Simplify.
3917 (vx_run_ops): Turn off all_mem, to avoid spurious msg in the
3918 "info files" output, and create_inferior, since we already have
3921 * stack.c (frame_info): Replace Frame_unknown with 0.
3922 (print_frame_arg_vars): Handle LOC_LOCAL_ARG.
3923 (return_command): Pop until the PC matches as well as the FP,
3924 so it works even if the FP is shared with another function,
3925 as in "frameless" or "leaf" procedures.
3927 * symfile.c (load_command): renamed from add_file_target_command.
3928 (add_syms_addr_command): renamed from add_file_addr_command.
3929 (add_syms_command): Stub to call target_add_syms.
3930 (_initialize_symfile): Change command names and descriptions,
3931 add-file => add-syms, and load from alias to its own command.
3933 * target.c (kill_or_be_killed, maybe_kill_then_attach,
3934 maybe_kill_then_create_inferior): Default for attempts to start
3935 a process, if one is already running, is to ask about killing
3936 it and retry if yes.
3937 (upstack_create_inferior): #if-0 it, strata obsolete it.
3938 (push_target, unpush_target, pop_target): to_close() a target
3939 before unstacking it.
3940 (target_info): Renamed from target_files_info.
3941 (_initialize_targets): Rename "i files" as "i target", accessible
3944 * target.h: Improve comments about the target_ vectored routines.
3946 * tm-i960.h: Remove NINDY-specific stuff to tm-nindy960.h.
3947 Convert commenting style to standard GNU style.
3948 (DBX_PARM_SYMBOL_CLASS): allow LOC_LOCAL_ARG's to be recognized.
3949 (SKIP_PROLOGUE): No longer a no-op.
3950 (SAVED_PC_AFTER_CALL): Now handles leaf procedures.
3951 (*_REGNUM): Sort register numbers.
3952 (REGISTER_BYTES, REGISTER_BYTE, REGISTER_RAW_SIZE,
3953 MAX_REGISTER_RAW_SIZE, REGISTER_CONVERTIBLE,
3954 REGISTER_CONVERT_TO_VIRTUAL, REGISTER_CONVERT_TO_RAW): Float regs
3955 are now 10 byte extendeds, not 8 byte doubles.
3956 (FRAME_CHAIN_VALID): Make this config-dependent, since it differs
3957 for nindy versus vxworks targets. FIXME, this should possibly go
3958 in the target vector.
3959 (EXTRA_FRAME_INFO, INIT_EXTRA_FRAME_INFO): Cache both
3960 frame_saved_regs and arg pointer with each frame.
3961 (FRAMELESS_FUNCTION_INVOCATION): New leafproc support.
3962 (FRAME_ARGS_ADDRESS): Use cached result.
3963 (FRAME_ARGS_ADDRESS_CORRECT): New, avoids g14 guessing.
3964 (FRAME_FIND_SAVED_REGS): Change arg to subsidiary fn.
3965 (PRINT_RAMDON_SIGNAL): Call print_fault.
3966 (POP_FRAME): Now works.
3968 * tm-nindy960.h: Break this off tm-i960.h. NINDY-specific
3969 option parsing and startup; STACK_END_ADDR, FRAME_CHAIN_VALID,
3970 BREAKPOINT, and DECR_PC_AFTER_BREAK are here.
3971 (ADDITIONAL_OPTION_HANDLER): use target_load, not
3974 * tm-vxworks960.h: Break this off tm-i960.h. VxGDB specific
3975 startup; DECR_PC_AFTER_BREAK, and FRAME_CHAIN_VALID are here.
3977 * valarith.c (value_subscripted_rvalue): Avoid handling
3978 floats and doubles specially; it gave alignment errors. Lint.
3980 * valops.c (value_of_variable, value_of_this): Error if unknown
3983 * valprint.c (print_floating): Bcopy rather than pointer-deref,
3984 to avoid alignment problems.
3985 (value_print): Handle unknown value address.
3986 (cplus_val_print): Two args are ignored; remove them. Change caller.
3987 (val_print): Use unpack_long rather than pointer-deref.
3990 (unpack_long, unpack_double): Use bcopy rather than pointer-deref
3991 to avoid alignment problems.
3992 (value_being_returned): Error if return value unknown.
3993 (set_return_value): Add bogosity warning, FIXME. *
3995 * TODO: A woman's work is never done.
3997 * Makefile.dist: Distribute REMOTE_OBS into tconfig files.
3998 Separate INCLUDE_CFLAGS for use with lint. Add LINTFILES.
3999 Add ieee-float.o to OBS.
4000 * tconfig/{nindy960,vxworks68,vxworks960}: Include the desired
4001 REMOTE_OBS remote-interface files in the TDEPFILES and TM_FILE.
4002 * tconfig/i960: FIXME. Half-merge, produce warning if config'd.
4004 Changes to generalize the VxWorks RPC protocol slightly, to handle
4005 i960 as well as 68000.
4007 * vx-share/dbgRpcLib.h (VX_SOURCE_STEP): Add.
4008 * vx-share/reg.h: Produce i960 regs #ifdef I80960
4009 * vx-share/xdr_ptrace.c: Skip FPA registers if 960.
4010 * vx-share/xdr_rdb.h: Add SOURCE_STEP struct and xdr decl.
4011 * vx-share/xdr_rdb.c: Add xdr_SOURCE_STEP routine.
4012 * vx-share/xdr_regs.c: Add xdr_regs, xdr_fp_status, xdr_ext_fp
4013 for i960. Change xdr_vectors to xdr_opaques for 68k registers,
4014 so they will move in target byte order rather than network
4015 byte order (happens to be the same).
4017 Mon Feb 25 03:41:44 1991 John Gilmore (gnu at cygint.cygnus.com)
4019 * tm-convex.h (END_OF_TEXT_DEFAULT): Remove #if 0'd block.
4021 Sun Feb 24 00:55:53 1991 John Gilmore (gnu at cygint.cygnus.com)
4024 Add contribution lines to various files, showing where they
4027 * breakpoint.c (break_insn, check_break_insn_size,
4028 read_memory_nobpt): Remove to mem-break.c.
4030 * xm-*.h, param-no-tm.h, tm-29k.h, valprint.c: Change BYTE_ORDER to
4033 * tm-29k.h (STAB_REG_TO_REGNUM): Warn user if symbol table
4034 entry has bad register number. This change is not
4035 tested in this release, FIXME.
4037 * frame.h: Eliminate Frame_unknown in favor of a simple zero.
4040 * value.h: Force value's contents field to be aligned to hold
4041 at least a double or a long long (if supported). This avoids
4042 doing bcopy's in and out of the contents field.
4044 (step_1): Avoid coredump under obscure circumstances when we
4047 * symtab.h (misc_info): Add field to misc function vector for
4048 any kind of cached information the target code desires. AMD
4049 29000 uses this to avoid repeating examine_function_prologue's.
4051 * coffread.c: Lint. Remove static symfile, read_section_header.
4052 core.c (have_core_file_p): Lint: remove.
4053 expprint.c (print_subexp): Lint.
4054 infptrace.c, valops.c, valprint.c: lint.
4056 Roll in changes from vxgdb-5.0.1:
4058 * symtab.h: Comment byte order of each address class. Add
4059 LOC_LOCAL_ARG for frame-relative args (960).
4060 expread.y: Use LOC_LOCAL_ARG where LOC_ARG is used.
4061 symtab.c, symmisc.c: ditto.
4063 * infrun.c (init_wait_for_inferior): Clear stop_signal.
4065 * remote.c (remote_resume): Error if resume with a signal.
4067 * symfile.c (prim_record_misc_function): Clear misc_info.
4068 (fill_in_vptr_fieldno): Check stub type of arg.
4070 * valops.c (value_cast): Avoid looking up names of types whose
4071 name we don't know, to prevent coredump. Sun CC produces typedef
4072 rtx and the name of *rtx is zero...
4074 Mon Feb 18 21:16:25 1991 John Gilmore (gnu at cygint.cygnus.com)
4076 Roll in changes from final AMD 29000 port (Tiemann).
4078 tconfig/am29k: Add COFF_ENCAPSULATE and TARGET=TARGET_AM29K
4079 for ../include/a.out.encap.h. This might not work now that BFD
4080 is separately compiled. Instead, BFD support for encap will have
4081 to translate machine type 29k into the right COFF_MAGIC.
4083 * infcmd.c: Remove references to inferior_pid that aren't used
4084 in actual ptrace calls; use target_has_execution, etc.
4085 (have_inferior_p): Remove function.
4086 (program_info): Print target info rather than "process number";
4087 avoid gratuitous messages unless from_tty.
4088 (run_stack_dummy, finish_command): Set proceed_to_finish.
4089 infrun.c: Remove inferior_pid refs. Decl & init proceed_to_finish.
4090 main.c: Lint. Lose have_inferior_p().
4091 inferior.h (have_inferior_p): Remove, lint.
4092 (proceed_to_finish): Add flag to ask that all regs be saved
4093 by normal_stop, for the few commands that need it, speeding up
4094 serial I/O. Add comments to stop_registers.
4096 * remote-eb.c: Remove newline from breakpoint message we grep
4097 for. Never time out when running the user program.
4101 Wed Feb 13 15:34:40 1991 John Gilmore (gnu at cygint.cygnus.com)
4103 Roll in changes from vxgdb-5.0.1:
4105 * dbxread.c (read_dbx_symtab): If we encounter a "FORTRAN COMMON"
4106 symbol in its raw form, we are processing an unlinked ".o" file.
4107 See if the target environment has assigned it an address, using
4108 target_lookup_symbol (VxWorks does), and enter it into the symtab
4111 * tm-vxworks.h (FRAME_CHAIN, FRAME_CHAIN_VALID): Override usual
4112 68k versions for a simpler version that assumes zero FP at bottom.
4113 Fixes bug of truncated stack reports.
4115 * target.h (target_lookup_symbol): Define this routine's args
4116 and result, finally.
4118 * target.c (nosymbol): Default routine for target_lookup_symbol.
4119 (target_default): Default lookup_symbol and call_function too.
4120 (files_info): Only print has_all_memory warning if a non-dummy
4123 * remote-vx.c (vx_read_register, vx_convert_to_virtual,
4124 vx_convert_from_virtual): If target does not have floating point,
4125 zero register "values", and avoid doing cross-net conversions.
4126 (vx_lookup_symbol): Rename net_lookup_symbol, add to vectors.
4127 (vx_open): Rearrange code that attaches to target and reads
4128 symbols for all loaded modules, to work if some of the modules
4129 are not accessible. Add symbol_stub() and add_symbol_stub()
4130 as callbacks from catch_errors(). Allow connect attempt to be
4131 interrupted painlessly with ^C (FIXME, there are still some bugs
4132 if the interrupt happens during symbol reading.). Print
4133 final message with puts_filtered, since symbol messages are
4138 * main.c (catch_errors): Only print errstring if non-null.
4139 (command_loop): Avoid an ioctl per command to test ISATTY.
4141 * remote-vx.c (net_load): make static; avoid sophomoric msg.
4142 (vx_xfer_memory): Return correct result!
4143 (vx_files_info): Indicate whether target has float or not.
4144 (vx_lookup_symbol): Complain, not error, if target gone.
4145 (vx_open): Print "Connected" msg before disabling immediate-quit.
4146 [FIXME: lookup_symbol and vx_open changes need testing.]
4148 target.c, remote-eb.c, inftarg.c, am29k-opcode.h, target.h,
4149 tm-29k.h, tmm-vxworks68.h, symfile.c, gdb-int.texinfo: Add
4150 contributor lines and update copyrights to 1991.
4152 Changes from an attempted H-PUX host port:
4154 * infptrace.c (PT_ATTACH, PT_DETACH): Handle HP/UX, which
4155 defines PT_ATTACH and PT_DETACH but not PT_KILL.
4156 * remote-eb.c (eb_open): Misplaced endif kills sysv H/PUX.
4157 * remote-vx.c: include <sys/time.h> for HPUX.
4158 * hp300hpux-xdep.c (fetch_core_registers): Rewrite old
4159 "core_file_command" routine to BFD regime. May not work yet.
4161 Attempted port of "gdb-3.4 Van Jacobson xgdb" to modern gdb.
4163 * xgdb.c: Replace X10 version with some VJ version.
4164 (FIXME: Its copyright assignment is not on record.)
4165 * xgdb.c: Update include files to X11R4 (Xaw crud).
4166 (xgdb_display_source, create_text_widget): fix call to
4167 get_filename_and_charpos. Rewack source window stuff for X11R4
4168 (gleaned from include files, and "nm's" of binary libraries, since
4169 I had no doc available).
4170 (append_selection, append_selection_word): Disable with FIXME
4171 since R4 changed interface here.
4172 (create_buttons): Add back the old set of buttons.
4173 (xgdb_create_window): Fix call to XtInitialize (&argc not argc).
4175 * Makefile.dist (xgdb, xgdb-init.c): Update for X11R4 on Suns.
4176 Roll VERSION to 3.94 (not yet final though).
4178 Sat Feb 9 09:46:25 1991 John Gilmore (gnu at cygint.cygnus.com)
4180 * obstack.h (obstack_ptr_grow, obstack_ptr_grow_fast,
4181 obstack_int_grow, obstack_int_grow_fast): Eliminate
4182 cast on left of assignment, which gives MIPS cc fits and is
4185 * sparc-pinsn.c (print_insn): Eliminate 'set' test, subsumed by
4186 F_ALIAS. Use printf, not fprintf, when not passing a file
4188 (compare_opcodes): Check that identical instructions have
4189 identical opcodes, complain otherwise.
4191 * sparc-opcode.h (st %fsr): Fix opcode "lose" mask. This
4192 was reported by Roland McGrath.
4193 (unimp): Only match if exactly zero instruction. (Roland)
4194 (branches and traps): Generate all variations of these
4195 instructions with macros, based on a single call that defines
4196 each condition name and its binary representation.
4197 (set): Turn on alias bit, to avoid test in sparc-pinsn.c.
4199 * valprint.c (val_print_fields): Take, and use, format parameter.
4200 This means that "p/x struct" again prints the elements in the
4201 desired format. Changed callers.
4203 * stack.c (frame_info): Use filtered output, and indicate wrap
4204 points. Remove kludgy formatting designed to avoid line wrap.
4206 * utils.c (wrap_here): If the line is already full (because
4207 we had printed a long indent or long wrapped string), do an
4208 immediate newline-and-indent.
4210 * m68k-pinsn.c (print_insn_arg): Bugfix from
4211 ntmtv!thompson@ames.arc.nasa.gov (Mike Thompson): 'bkpt #0'
4212 instruction is incorrectly disassembled as bkpt #8.
4214 * dbxread.c (end_psymtab): Bugfix from Peter Schauer
4215 <pesrem@regent.e-technik.tu-muenchen.de>: If you want to set a
4216 breakpoint in a *.y file gdb will say Reading in symbols for *.y...
4217 and then will dump core (sometimes). I traced it back to an
4218 uninitialized symfile_name in psymtab_to_symtab.
4219 (const_vol_complaint): Add quotes to message.
4220 (define_symbol): Only believe line number if gcc_compiled.
4221 Avoid allocating symbol if we will not return it.
4223 Add target strata support so that newly established targets go
4224 into their right place in the target stack (e.g. a new exec file
4225 doesn't wipe out the ability to access the running process).
4227 * target.h, core.c, exec.c, inftarg.c, remote-eb.c,
4228 remote-nindy.c, remote-vx.c, remote.c, target.c: Add to_stratum
4229 and initialize it properly in all the targets.
4231 * target.h: Document strata. Change return type of push_target.
4233 * target.c (nomemory): new function for dummy memory access.
4234 (tcomplain): Rename complain, now also used in symfile.c.
4235 (push_target): Push targets within strata. New return value shows
4236 whether new target is on top of stack or not. Always keep dummy
4238 (target_files_info): Ignore dummy target.
4240 * core.c (core_open): Warn user, and skip accessing file, if the
4241 core target is not the topmost target in the stack.
4242 * remote-nindy.c (nindy_create_inferior): Avoid unpush_target, now
4245 * remote-vx.c: Remove vx_prepare_to_store from vxworks memory
4246 target_ops, it doesn't belong there since we have no regs there.
4247 Change name of target from machine => memory to clarify.
4249 Thu Feb 7 16:32:09 1991 John Gilmore (gnu at spiff.cygnus.com)
4251 * Freeze version 3.93 for release.
4253 * Makefile.dist: Handle vx-share and nindy-share subdirs
4254 properly when building gdb.tar.Z.
4256 * symtab.c: lint; add no_symtab_msg to consolidate the messages
4257 printed in various places, so I could change just one copy.
4259 * dbxread.c, coffread.c: Change references to bfd->iostream
4260 to cast to FILE *, now that BFD avoids needing types defined
4261 in other header files.
4263 Tue Feb 5 21:39:35 1991 John Gilmore (gnu at cygint.cygnus.com)
4265 * command.c, dbxread.c, expprint.c, infcmd.c, infptrace.c,
4266 infrun.c, printcmd.c, remote-nindy.c, source.c, sparc-tdep.c,
4267 sparc-xdep.c, symfile.h, symmisc.c, utils.c, valprint.c: Lint
4268 (actually gcc -Wall).
4270 * dbxread.c: Remove first_global_sym, last_global_sym, since
4271 they are never referenced.
4273 * defs.h (baud_rate): Declare.
4274 main.c: Define it, and add the -b option to set it.
4276 * gdb-int.texinfo: Add text on how to define a new host or target
4277 architecture, prompted by Per Bothner's questions about MIPS
4280 * gdb.texinfo: Document "complaints". Change doc of -q since
4281 gdb no longer prints the copyright and blurb if you specify a file
4282 name to be debugged (just like Emacs). Add doc for Nindy-specific
4283 command line flags for specifying target serial port and such.
4284 Update copyright to 1991.
4286 * gdbcore.h: Remove a large mass of now-useless crud, since BFD
4287 has taken over for us the job of ripping up executable files. The
4288 crud caused Per Bothner's port to not compile.
4290 * infrun.c (normal_stop): Avoid printing "Program exited
4291 normally" if we are in batch mode. This allows a GDB which
4292 executes a program on a target system, to behave like a Unix
4293 command (input from stdin, output to stdout, no extraneous
4296 * main.c (main): Allow additional machine-dependent command line
4297 options to be specified with the ADDITIONAL_OPTIONS,
4298 ADDITIONAL_OPTION_CASES, ADDITIONAL_OPTION_HELP, and
4299 ADDITIONAL_OPTION_HANDLER macros. Also allow machine-dependent
4300 processing to occur just before the main loop with
4301 BEFORE_MAIN_LOOP_HOOK.
4302 (main): If a "core file" argument is specified, and it is not a
4303 core file, try it as a process ID to attach.
4304 (symbol_completion_function): Attempt to cope with
4305 "show screen-" TAB, not very successfully. This needs more work,
4307 (batch_file): New function, returns whether we are reading
4308 commands from an interactive tty on stdin, or from somewhere else.
4309 Called by normal_stop since it doesn't get from_tty passed down
4310 to it like many commands do.
4312 * remote-nindy.c: Handle command line options for nindy
4314 (nindy_before_main_loop): Prompt user for tty name if they
4315 don't specify it before getting to the interactive command loop.
4317 * tm-i960.c: Add ADDITIONAL_OPTIONS, etc, to handle -O, -brk,
4318 and -r command line options. Also add hook before main loop
4319 to make it easy to specify a tty.
4321 * TODO: More things to do, one done.
4323 Mon Feb 4 23:57:39 1991 John Gilmore and Mike Tiemann (at cygint.cygnus.com)
4325 * dbxread.c: Make complaint() calls pass pointer, not struct.
4326 Add complaints about badly formatted C++ type information
4327 (const/volatile indicator, and parse errors resulting in
4328 error_type). Fix C++ virtual member fn comment.
4329 (read_struct_type): Avoid bumping pointer if we got a parse
4330 error; this prevents our walking beyond the end of a string.
4331 Terminate loop on null char as well as semicolon.
4332 (process_one_symbol): Fix the LBRAC fix so that it uses the
4333 last previous SLINE, FUN, or SO record's PC address. C++ debug
4334 symbols did not have SLINE records in a useful order compared
4335 to the LBRAC records.
4336 (define_symbol): Handle "catch" records.
4338 * symtab.c (check_stub_type): Added new complain
4339 `stub_noname_complain' and added a consistency check to
4340 keep the debugger from crashing when finishing from an
4341 exception frame. A real fix will be needed later.
4343 Sat Feb 2 10:43:05 1991 John Gilmore (gnu at cygint.cygnus.com)
4345 * infcmd.c (attach_command): Make global.
4347 * Makefile.dist (REMOTE_OBS): Make these compile by default,
4348 but make them easy to comment out. Perhaps later they should
4349 be enabled by what CPU you configure for? FIXME.
4350 (VERSION): Roll to 3.93.
4351 (pinsn.o): Remove rule for obsolete file.
4352 (dbxread.o,coffread.o,mipsread.o): Use ${srcdir} explicitly.
4354 Run down a problem that manifested by printing the wrong function
4355 name in stack traces of read_ofile_symtab. Turned out that the
4356 problem was the SunOS 4.1.1 (and previous) C compiler outputs
4357 the LBRAC symbol with an address in the *data* segment, which
4358 blew our binary search through the blocks.
4360 * dbxread.c: Use the complain() facility consistently to bitch
4361 about problems in the symbol file we are reading.
4362 (finish_block): Add code to check the nesting of the blocks;
4363 complain and Procrust them to fit if wrong.
4364 (make_blockvector): Check the order of the blocks, complain
4365 [but don't cope] if wrong.
4366 (process_one_symbol): ifndef SUN_FIXED_LBRAC_BUG, check LBRAC
4367 symbols to be sure their PC value is greater than the last SLINE
4368 (line number) symbol we've seen, complaining and adopting the
4369 SLINE PC value if wrong.
4371 * symfile.h (struct complaint, complaint_root, complain,
4372 clear_complaints): Add.
4373 * symfile.c (complain, complaint_root, clear_complaints): Add
4374 facility to deal with non-fatal complaints and to regularize their
4376 (symbol_file_add): Clear complaint counters to allow new complaints.
4377 (initialize_symfile): Add 'set complaints' and 'show complaints'.
4379 * dbxread.c (dbx_symfile_read): Remember the address and size
4380 of the string table for the main symbol file, so we won't read it
4382 (dbx_psymtab_to_symtab): Fix the check for main symbol file,
4383 to avoid reading the string table yet again. Lint.
4384 (throughout): Improve filtered output, including word wrap.
4385 (read_range_type): Improve Bothner's fix to handle other types too.
4387 * utils.c: Improve line wrap implementation. Handle unlimited
4388 width by making chars_per_line unsigned.
4389 (puts_filtered): New, easy, function.
4391 * defs.h (puts_filtered): add.
4393 * mipsread.c (compare_symbols, sort_symtab): Remove these fns,
4394 call the identical sort_symtab_syms() in symfile.c instead.
4396 * expread.y: Suggest the `file' command rather than `symbol-file'.
4398 * command.h (enum var_types): Add zinteger for seroable
4400 * command.c (do_setshow_command): Handle var_zinteger. Restructure
4401 nested if's into a switch.
4403 * breakpoint.c (bpstat_print): If bpstat "print" flag is not set,
4404 we did not stop because of a breakpoint (it must have been for
4405 some other reason, like a "stepi"), so don't print anything.
4407 * symtab.c: Include <sys/types.h> all the time. Now that BFD
4408 doesn't include <sys/types.h>, old SunOS's require it for
4411 Sat Feb 2 10:39:15 1991 Per Bothner (bothner@cs.wisc.edu)
4413 A test port of gdb-3.92.6 to the Sony NEWS.
4416 Don't normally link in remote- or vx stuff.
4417 Some of it doesn't compile, and it wastes space for 99% of the users.
4418 Remove reference to no-longer-used HAVE_VPRINTF.
4419 Fixed BFD_DEP typo to BFD_DIR.
4421 Fix cast in arg to bfd_h_getlong.
4422 Make char *prefix be const.
4423 Fix how certain range types are mapped into builtin unsigned int types.
4425 Remove 2 #includes. They cause errors (on Sony, at least),
4426 and aren't needed (they wern't in earlier versions).
4428 print_address_symbolic should never demangle labels
4429 (since it prints *assembler-level* labels).
4431 [This was superseded by the change to printcmd below.]
4434 Add some "volatile" return types to avoid warnings.
4435 If MISSING_VPRINTF add vprintf function and not just macro
4436 (since vprintf is used in printcmd.c).
4438 Unless __GNUC__, use obstack_grow instead of obstack_ptr_grow.
4439 (The latter isn't grokked by some PCC-based compilers.)
4441 [This change is in abeyance, we prefer to fix obstack_ptr_grow.]
4443 Make chunk size of dont_print_obstack 32*4 instead of default 4096.
4444 * nindy-share/coffstrip.c
4445 Added some forward declarations (otherwise, gcc complains
4446 about implicit extern redefined as static).
4448 Sun Jan 20 02:38:19 1991 John Gilmore (gnu at cygint.cygnus.com)
4450 Changes inspired by Per Bothner:
4451 * printcmd.c (print_address_symbolic): Take additional parameter
4452 specifying whether to demangle.
4453 (print_address): Pass in asm_demangle to control demangling.
4454 (print_address_demangle): New fn, takes explicit arg to control
4456 * utils.c: Add new vars demangle and asm_demangle, and let them
4458 (fputs_demangled): If !demangle, just print the argument.
4459 (fprint_symbol): If !demangle, just print raw symbol.
4460 * valprint.c (val_print): Call print_address_demangle rather than
4461 print_address, to cause demangling to depend on the global
4462 rather than assembler-level demangling setting.
4463 * WHATS.NEW, gdb.texinfo: Document.
4465 * main.c (show_command): Show all settings if no arg.
4466 (initialize_main): Make "info set" the same as naked "show".
4467 * command.c (cmd_show_list): Handle prefix commands in the
4468 list, and print the name of the setting as well as its English
4469 description and value.
4471 Allow gdb functions to specify where a line should wrap if it
4472 exceeds the size of a terminal line. Use it to make the output
4474 * utils.c (set_screen_width_command): New fn, mallocs a buffer
4475 of the right size when screen width changes.
4476 (set_screensize_command, screensize_info): Remove #if 0'd fns.
4477 (wrap_here): New fn, indicates a point in the output where we
4478 should wrap the line rather than just letting it overflow at a
4480 (fputs_filtered): Implement wrapping.
4481 (n_spaces): New fn, returns a pointer to N spaces.
4482 (print_spaces_filtered): Use n_spaces.
4483 * defs.h (n_spaces): Declare.
4484 * stack.c (print_frame_info): Wrap with 4-space indent after
4485 fn name and before filename and line number.
4486 * printcmd.c (print_frame_args): Wrap with 4-space indent
4487 before each argument name is printed.
4488 * valprint.c (value_print): Wrap with no indentation before
4490 (val_print_fields): Wrap with indentation relative to nesting
4491 level before each field name.
4492 (val_print): Wrap with nesting indentation before array elements.
4493 * command.c (do_setshow_command): Avoid extra newlines,
4494 wrap with 4-space indent around values printed, end with period.
4495 * WHATS.NEW, gdb.texinfo, gdb-int.texinfo: Document.
4497 * breakpoint.c (breakpoint_1): Implement addressprint for
4498 "info breakpoints" display. Change file name and line number
4499 format to " at file:nnn" rather than " (file line nnn)".
4500 * gdb.texinfo: Document.
4503 Fri Jan 18 07:21:25 1991 John Gilmore (gnu at cygint.cygnus.com)
4505 Frozen for gdb-3.92.6 release.
4507 README, WHATS.NEW: Update for 3.92.6 release.
4509 tconfig/{altos, i386v, i386v32, m88k, umax}: Eliminate
4510 coffread.o from configs since it is now built by default.
4511 tconfig/{3b1, altosgas, arm, convex, hp300bsd, hp300hpux,
4512 i386v-g, i386v32-g, isi, merlin, news, news1000, np1, pn,
4513 pyramid, symmetry, vax, vxworks68}: Eliminate dbxread.o
4514 from configs since it is now built by default.
4516 Makefile.dist: Update for release 3.92.6. Handle files that
4517 have been moved to ../include, ../getopt, or ../bfd. Add
4518 saber.suppress and tests directory. Add config.status to
4519 the release (it will say "none").
4521 coredep.c: Minor formatting fixes.
4523 These changes were made in early December but only checked in now:
4524 * nindy-share/Onindy.c, nindy-share/coffstrip.c,
4525 nindy-share/nindy.c: lint
4526 * nindy-share/nindy.c (ninStopWhy): Don't byteswap the
4527 register values coming back from the target; we store values
4528 in target byte order everywhere.
4530 Wed Jan 16 19:01:37 1991 John Gilmore (gnu at cygint.cygnus.com)
4532 * am29k-opcode.h, am29k-pinsn.c: Add 29050 opcodes.
4534 * valprint.c (cplus_val_print, val_print_fields): New functions,
4535 which print C++ objects. They conspire to avoid printing a
4536 virtual base class more than once, following all the twists and
4537 turns of C++ virtual base rules.
4538 (val_print): Call the above rather than do it by hand.
4540 * symfile.c (symbol_file_add): Only reset symfile_mtime for main
4541 symbol file, not for added files like shared libs. This really
4542 needs to be generalized to a timestamp per file.
4544 * core.c (cleanup_core): Avoid coredump if no core file.
4546 * config.gdb: Accept -host or -target in place of +host or
4549 * coffread.c (find_linenos): Avoid desupported BFD interface
4550 to line numbers. We still read them manually rather than using
4551 BFD's "generic" features.
4553 * gdbrc.tex, threecol.tex: Add GDB reference card and its
4555 Makefile.dist: Add refcard to OTHERS list for creating tar files.
4557 * Makefile.dist: Eliminate use of $< in explicit targets.
4559 * readline/Makefile: Use $< rather than $*.c, which does not
4560 include the VPATH in GNU Make.
4562 * tconfig/i960-bout, tconfig/i960-coff: These are identical
4563 copies of tconfig/i960, added for global configuration
4564 compatability. All i960 versions can read both coff and b.out.
4566 * tm-88k.h: Fix multiline macro that lacked \'s. Remove
4567 COFF_FORMAT and COFF_CHECK_X_ZEROES since these are now handled
4570 * TODO: Think of more things to do.
4572 Wed Jan 2 19:09:29 1991 John Gilmore (gnu at spiff.cygnus.com)
4574 tconfig/{am29k,i960,sun2*,sun3*,sun4*}: Eliminate config
4575 of sdb versus dbx debug symbols. Add kludge for 68881 80-bit to
4576 64-bit float conversion.
4578 tconfig/sun4, tconfig/sun3, xconfig/sun4, xconfig/sun3: Make
4579 equivalent to sun?os4 so global config works.
4581 Wed Jan 2 18:20:51 1991 John Gilmore (gnu at spiff.cygnus.com)
4583 Fix from Eberhard Mattes <mattes@azu.informatik.uni-stuttgart.de>
4585 * main.c: Only declare linesize once; declare pagesize not at
4586 all, since it is never used.
4587 (main): Clear newly allocated line before it is used.
4589 Fri Dec 28 00:13:42 1990 John Gilmore (gnu at cygint)
4591 Further stabilization for the Intel 960.
4593 * Makefile.dist: Parameterize the location of the "include"
4594 and "bfd" directories, as well as "getopt". Add symfile.c.
4595 Link in both dbxread and coffread. Fix up "make depend" to
4596 rewack the locations of include, bfd, and getopt in its output.
4598 * README: Document moving include files, improve some of
4601 * coffread.c: Move common code out to symfile.c. Change
4602 symbol_file_command style interface to use new *_symfile_init
4603 and *_symfile_read interface under BFD. Use BFD internal
4604 info to locate line table, symbols, etc.
4606 * core.c (core_fetch_registers): Rename to get_core_registers
4607 to avoid confusion with fetch_core_registers.
4608 (register_addr): Move to coredep.c, which is already machine
4609 dependent. This leaves core.c pretty clean of dependencies.
4611 * coredep.c (register_addr): Accept this routine from core.c.
4613 * dbxread.c: Move common code (with coffread.c, etc) into new
4614 symfile.c. Each psymtab now contains a pointer to the
4615 format-dependent function that knows how to read it in. Make
4617 (dbx_psymtab_to_symtab): Renamed from psymtab_to_symtab_2.
4618 (process_one_symbol): Add code to complain about a "compiler bug
4619 we muzzle here", if we actually see it.
4621 * eval.c (evaluate_subexp): Insert missing "break" statements
4622 in code that determines whether a variable is an lvalue in
4623 memory, register, or whatever. I detected this via a compiler
4624 bug in which it *almost* mashed out the whole switch statement.
4626 * gdb-int.texinfo: Add minor sections on configuring gdb for
4627 release, and about the README file.
4629 * infcmd.c (registers_info): Fix formatting somewhat. Still
4630 not as pretty as before, but it handles byte swapping.
4632 * remote-nindy.c: If data cache routines are interrupted while
4633 waiting for the remote end, be sure that any uninitialized cache
4634 blocks are on the free list, not on the valid list!
4636 * symfile.h: Flesh out this header file with all the various
4637 routines and variables that have been merged in from dbxread.c
4638 coffread.c, and symtab.c to symfile.c.
4640 * symfile.c: New file, containing code common to dbxread.c,
4641 coffread.c, and some code from symtab.c. All generic code for
4642 reading symbol files should be in here now.
4643 (unrecord_misc_function): Remove unused function.
4645 * symtab.h: Remove file-reading things to symfile.h.
4647 * symtab.c: Remove file-reading things to symfile.c.
4649 * tm-i960.h: Fix FRAME_CHAIN types; define PRINT_RANDOM_SIGNAL
4650 to decode i960 fault types.
4652 * target.h, remote.c, remote-eb.c, remote-vx.c, remote-nindy.c,
4653 target.c: Change type of the "resume" function from int to void,
4654 since its result was never used.
4656 Sat Dec 22 02:51:40 1990 John Gilmore (gnu at cygint)
4658 * main.c: Replace "stupid" with "caution"; you now "set caution
4661 * printcmd.c (print_scalar_formatted): Fix typo in 'g' format
4663 * infcmd.c (do_registers_info): Call val_print to deal with the
4664 byte order of the registers being printed. FIXME, this makes
4665 the formatting of the output uglier.
4667 * infcmd.c (wait_for_inferior): If PRINT_RANDOM_SIGNAL is
4668 defined, call it for signals the debugger doesn't itself use.
4669 The i960 uses this for more detailed fault information.
4671 * remote.c (remote_open): If arg is null, print help rather than
4674 * sparc-xdep.c (register_valid): Avoid declaring size, since
4675 various modules will think of various sizes depending on the
4676 architecture of their tm-file. FIXME, we need protection against
4677 actually entering one of those modules, which would clobber
4678 storage if not for the target architecture compiled into gdb.
4680 * stack.c (up_command, down_command): Always print the frame
4682 (up_silently_command, down_silently_command): New commands
4685 * i960-pinsn.c (reg), i960-tdep.c: Lint.
4687 * i960-tdep.c (i960_frame_chain_valid): Lookup_symbol now takes
4688 more parameters than it used to.
4690 * findvar.c (registers): Increase slop to 256 bytes, which should
4691 protect us against even most RISC machines with large register
4693 (locate_var_value): Move declaration inside related ifdef.
4695 * remote-nindy.c (): Use TIOCSETN rather than TIOCSETP
4696 throughout, to avoid throwing away buffered input from the board.
4697 (nindy_wait): Supply_register takes addr_of_value, not value.
4698 (i960_print_fault): Renamed from i80960_fault.
4699 (nindy_fetch_registers): Avoid have_regs stuff, just get them.
4700 (nindy_store_registers): Avoid regs_changed stuff, just stuff
4702 (nindy_create_inferior): Don't bother to write PC_REGNUM since
4703 we can set the PC in the call to proceed(). Unpush nindy_ops
4704 before pushing it on top, to avoid message to user. Eliminate
4705 commentary from Unix machines that just misleads here.
4706 (reset_command): Fix error message to suggest target command.
4708 Wed Dec 19 11:03:56 1990 John Gilmore (gnu at cygint)
4710 Release 3.92.5 as frozen.
4712 Stabilize the merged release...with help from lint, Saber C,
4715 Everywhere: Add include files needed to declare return types
4716 of functions called.
4718 * gdb.texinfo: Roland Pesch is documenting gdb, glory be!
4720 * breakpoint.h: Add undeclared breakpoint functions, and some
4721 functions for display handling since I couldn't think of a better
4724 * breakpoint.c (insert_breakpoints): Make code for disabling
4725 shared library bkpts more likely to work. It's used when we
4726 rerun a program and stop before the shared library has been
4728 (breakpoint_cond_eval, bpstat_stop_status): Pass arg as int,
4729 cast from pointer, so it squeezes through catch_errors.
4730 (bpstat_stop_status): Fix logic broken some time ago. We now
4731 always create a bpstat if the stop address matches a breakpoint,
4732 even if we don't stop there -- just like the old code used to do
4733 before I got my fingers into it (sigh).
4734 (breakpoint_1): Print "ignore count" after "stop only if"
4735 condition, since that's how it actually works.
4736 (mention): Handle watchpoints as well as breakpoints.
4737 (watch_command): use set_raw_breakpoint and mention to do most
4738 of the work (and initialize all the fields!). Only pass one
4739 arg to parse_c_expression, since that's all it takes.
4741 * command.c (not_just_help_class_command): Rename arg to args
4742 since we ignore "unused argument" warnings on vars named "args".
4743 inflow.c (child_terminal_info): ditto.
4744 infptrace.c (kill_inferior): ditto
4745 main.c (catch_errors, version_info, quit_command, pwd_command,
4746 source_command, dump_me_command, editing_info,
4747 set_history_size_command, set_history, show_history,
4749 stack.c (locals_info): ditto
4750 target.c (target_files_info): ditto
4751 valprint.c (set_input_radix, set_output_radix): ditto
4753 * core.c: Remove old variables for handling core and exec file
4754 sections (data_start, data_end, stack_start, stack_end,
4755 reg_stack_start, reg_stack_end, reg_stack_offset, text_start,
4756 text_end, exec_data_start, exec_data_end, text_offset,
4757 exec_data_offset, data_offset, stack_offset). They're
4758 superseded the more general build_section_table and
4760 (get_exec_file): Mention the `file' command.
4761 (read_memory_check): Rename to memory_error, and only call it
4762 in the case of an actual error.
4763 (read_memory, write_memory): call memory_error.
4764 (core_fetch_registers): Register section name is ".reg".
4766 coredep.c: Remove a bunch of crud now that all this file does
4767 is pull the registers out of a core file.
4768 (fetch_core_registers): Rewrite to actually work, I hope.
4770 dbxread.c: Use a.out.gnu.h, not system a.out, now.
4771 Replace index() with strchr(). Remove all the pre-BFD macro
4772 definitions for accessing the symbol file.
4773 (struct dbx_symfile_info): Encapsulate the information that
4774 dbx_symfile_init needs to pass to dbx_symfile_read in this
4777 (dbx_new_init, dbx_symfile_init, dbx_symfile_read,
4778 dbx_symfile_discard): Rearrange symbol file reading to divide
4779 the format-specific part from the format-independent part,
4780 leaving the format-independent part such as file name expansion
4781 and opening in symtab.c. This replaces
4782 partial_symbol_file_open and partial_symbol_file_read.
4783 Symbol_file_read, add_file, add_file_target_command,
4784 add_file_addr_command move to symtab.c. Pass an explicit
4785 "mainline" flag for when reading the main symbol table, rather
4786 than relying on the offset address to be zero or nonzero.
4788 (dbx_symfile_read): Don't allow void *'s to be printed as
4790 (SWAP_SYMBOL): Use bfd routines to byte-swap the symbols.
4791 (ADD_PSYMBOL_TO_LIST): Make the "function call rather than
4792 macro" debug version really work.
4793 (read_dbx_symtab): Remove unref'd parameter inclink.
4794 Avoid swapping N_SLINE symbols, for speed.
4795 Merge N_TEXT!N_EXT case with the other external symbol
4796 definitions' case. Add comments.
4797 (start_psymtab): Allocate the symfile name in the psymtab on
4798 the psymbol_obstack, rather than using the caller's storage.
4799 (end_psymtab): Only allocate a dependencies list if there are
4801 (psymtab_to_symtab_2): Use BFD when reopening file to read
4802 its symbols for real.
4803 (read_struct_type): Add FIXME comments where it needs work
4805 (read_huge_number): Add FIXME about overflows.
4806 (read_range_type): Add FIXME about comparing a long to 1<<32.
4808 * coffread.c: Minor changes to move things closer to the new
4809 regime with symtab.c and dbxread.c Major work is still needed
4812 * exec.c (exec_file_command): Remove old variables (see core.c
4814 (xfer_memory): If memory transfer is right at the end of a
4815 section, don't lose.
4817 * findvar.c (get_saved_register): If value is in a real
4818 register, LVAL is lval_register, not lval_memory.
4820 frame.h: Declare print_sel_frame and record_selected_frame.
4822 gdb-int.texinfo: New file, for GDB internals documentation.
4823 Very simple, unformatted doc of cleanups is there for now.
4825 gdbcore.h: Remove obsolete variables that described a.out
4826 section addresses and offsets. (See core.c above.)
4827 Declare fetch_core_registers and registers_fetched.
4829 getopt.c: Declare char *alloca(); even on SPARC.
4831 infcmd.c (run_command): Call target_kill rather than
4833 (step_command, next_command, stepi_command, nexti_command):
4834 Declare from_tty parameter even though we don't use it.
4835 (run_stack_dummy): argument BUFFER is a char array, not
4836 a pointer to REGISTER_TYPE.
4837 (finish_command): using_struct_return needed a value *,
4838 not a struct symbol *.
4840 * infptrace.c (child_xfer_memory): To avoid dependency on
4841 where sections are in memory, try PT_WRITE_D and if that fails,
4842 try PT_WRITE_I. Most Unixes don't care which you use.
4844 * infrun.c (step_resume_break_shadow): Change to array to
4845 match other breakpoint shadow storage.
4846 (clear_proceed_status): Pass address of bpstat to
4847 bpstat_clear, not the bpstat itself.
4848 (child_create_inferior): FIXME comment about if the child
4850 (start_inferior): Remove old function.
4851 (child_open): Use target_kill rather than kill_inferior.
4852 (wait_for_inferior): Ditto.
4853 (insert_step_breakpoint, remote_step_breakpoint): Use
4854 new step_resume_break_shadow.
4856 * inftarg.c (child_wait): If all child processes die,
4857 pretend that the one being waited for exited with signal 42.
4859 * main.c (command_line_input): When scanning for comments,
4860 don't coredump on unclosed quotes.
4861 (quit_command): Use target_kill rther than kill_inferior.
4862 (_initialize_main): Rename class_user from "user" to
4865 * printcmd.c (print_command_1): Initialize "fmt" if no format
4866 is specified by the user.
4867 (print_frame_args): Only add to args_printed if we are
4868 actually fetching args from the stack (avoiding undefined
4870 (_initialize_printcmd): Remove bogus \{ from string.
4872 * remote-eb.c (eb_open): Avoid coredump on no argument.
4874 * remote-nindy.c: Bring out of Intel environment into new
4875 target environment. Remove all conditional compilation on
4876 I80960. Massive hacking throughout.
4877 (nindy_xfer_inferior_memory): New routine stolen from
4879 (nindy_create_inferior): New routine pieced together, probably
4880 not quite working yet.
4881 (nindy_ops): New target_ops struct for nindy.
4883 * remote-vx.c: Use write_memory rather than target_write_memory
4884 to get error checking.
4885 (vx_add_file_command, vx_open): Use symbol_file_add rather than
4887 (vx_create_inferior): Use target_terminal_ours...
4889 * signame.c (_initialize_signame): Always initialize, since
4890 we need the table for things other than psignal.
4892 * solib.c (solib_add): Use symbol_file_add, not add_file.
4893 (solib_address): Return boolean result rather than struct
4894 pointer which nobody else knows the type of.
4896 * sparc-tdep.c, valops.c: Use write_memory rather than
4897 target_write_memory, to get error checking.
4899 * stack.c (locals_info, catch_info, args_info,
4900 get_selected_block, frame_command, up_command): Use
4901 target_has_stack, rather than have_inferior_p or
4904 * sun3-xdep.c (fetch_core_registers): Rewrite for new BFD regime.
4906 * symfile.h: New file, defining the interface between the
4907 generic and object-file-specific symbol reading code.
4909 * symtab.c: Move generic symbol-reading interface to symtab.c,
4910 from dbxread.c, coffread.c, mipsread.c, etc. Add symtab_fns
4911 table to map BFD targets to symbol-reading modules in GDB.
4912 Change index to strchr.
4913 (lookup_struct_elt_type): Use error() rather than hand-made
4914 simulations thereof.
4915 (lookup_partial_symbol): Speedup slightly when length == 0.
4916 (symbol_file_add): New function.
4917 (symbol_file_command): Call it.
4918 (symfile_open, symfile_init): New function.
4919 (add_file_target_command, add_file_addr_command): moved from
4922 * target.c (target_command): use target_kill.
4924 * target.h (target_files_info): Don't declare, never called
4927 * tm-sun2.h, tm-sun3.h (STACK_END_ADDR): Use system include
4928 files to determine stack end address.
4930 * valarith.c (value_x_binop, value_x_unop): Change error message
4931 to be more useful. Pass proper argument to value_struct_elt.
4933 * valops.c (value_assign): FIXME comment that long long
4934 bitfields will break here.
4936 * Makefile.dist: Add symfile.h, remote-nindy.c, remote-eb.c.
4937 Update `make saber_gdb' to work better.
4939 * TODO: A woman's work is never done.
4941 * cplus-dem.c, environ.c, inferior.h, infrun.c, inftarg.c,
4942 main.c, obstack.c, printcmd.c, remote-eb.c, remote-nindy.c,
4943 remote-vx.c, remote.c, solib.c, source.c, sparc-pinsn.c,
4944 sparc-tdep.c, sparc-xdep.c, symmisc.c, symtab.c, symtab.h
4945 target.c, terminal.h, tm-sparc.h, tm-sunos.h, utils.c,
4946 valops.c, valprint.c, exec.c: Lint.
4949 Wed Dec 12 23:44:15 1990 John Gilmore (gnu at cygnus.com)
4951 Continuing Intel 960 port merge of GDB.
4953 * Makefile.dist: Merge i960 "nindy-share" files. Rename
4954 malloc.h to gmalloc.h to avoid name conflicts in /usr/include.
4955 Don't ship gdb.dvi in tar file. Link gdb with init.o, not init.c.
4956 Wack over "make depend" so it handles files in subdirectories
4957 vx-share, nindy-share, bfd, and in the current directory.
4959 * blockframe.c (get_prev_frame_info): Remove fatal error
4960 if stack not defined.
4962 * core.c (core_open, core_detach): New functions that handle
4963 the old "core-file" command as "target core" and "detach" instead.
4964 (core_file_command): Call them.
4965 (core_xfer_memory): Use common routine xfer_memory.
4967 * dbxread.c: Include a.out.gnu.h, not system a.out.h.
4968 dbxread now uses bfd for everything but symbol reading itself.
4969 BFD internals are used to drag out the relevant file offsets.
4970 (partial_symbol_file_open): Change args all around for BFD.
4972 * symtab.c: Rename "value" to "val" everywhere, so we can
4974 (symbol_file_command): New command, moved from dbxread.c
4975 and coffread.c. It uses BFD to read the file, then vectors
4976 based on its type, to dbx or coff symbol readers.
4977 * symtab.h: Extern a few vars for symbol_file_command.
4979 * target.h: Breakpoint takes a char * save area, not a char **.
4981 * valprint.c (val_print): When unpacking bitfields, offset
4982 the address in gdb of the value, if it is declared with a shorter
4983 type. Remove the last "runtime kludge test" of host byte order.
4985 * utils.c: Remove old my_bfd_read routine.
4987 * stack.c (frame_info): Use target_has_stack. Print program counter
4988 register's actual name rather than "pc", since it's called the
4989 "ip" (instruction pointer) on the i960 (sigh).
4991 * target.c (target_command): Add command for selecting a target
4992 type and calling its open routine. This is used for initiating
4993 communication with a particular target, in a generic way.
4995 * tm-i960.h: Update for modern gdb. Remove semicolons from
4996 various macros. Handle reading struct return convention, and
4997 error-out attempts to return structs with the "return" command.
4998 Be sure gdb doesn't think we know how to call functions in the
5001 * i960-tdep.c: Rename FRAME_CHAIN_VALID and FRAME_FIND_SAVED_REGS
5002 to i960_xxx in lower case.
5003 (arg_address): Circumvent errors due to LOC_ARG_BLOCK
5004 not being defined yet.
5006 * remote.c (remote_open): Call start_remote to initialize
5007 wait_for_inferior during open.
5008 (remote_xfer_inferior_memory): Return length written rather
5011 * remote-vx.c (target_command -> vx_open): Use new generic
5013 * remote-eb.c, inftarg.c, exec.c: ditto.
5015 * infrun.c: Fix comments.
5016 (attach_program -> child_open): Use new generic target command.
5017 (wait_for_inferior): Clear saved register values before target_wait,
5018 so target_wait can set some of them if convenient.
5020 * infptrace.c (fetch_inferior_registers, store_inferior_registers):
5021 Return success indicator, not void.
5022 (child_xfer_memory): Avoid fetching initial word if we'll
5023 overwrite it anyway.
5025 * infcmd.c (attach_command): Use new generic target open routine.
5026 (_initialize_infcmd): Update doc on attach and detach commands.
5027 (do_registers_info): Merge in a byte-order problem as a FIXME
5030 * findvar.c (find_saved_register): Avoid problem in current frame.
5031 (read_relative_register): Ditto.
5032 (write_register): Convert byte order on the way out.
5034 * exec.c (file_command): Add.
5035 (add_to_section_table, exec_command): Use new bfd_map_over_sections.
5036 (xfer_memory): Common function between core_xfer_memory and
5038 (exec_xfer_memory): Use it.
5040 * pn-opcode.h: Document that a "PN" is a Gould PowerNode.
5042 * breakpoint.c, breakpoint.h, symtab.h, value.h, frame.h, utils.c,
5043 valops.c, stack.c, target.c, sparc-xdep.c, source.c, printcmd.c,
5044 infcmd.c, i960-pinsn.c, eval.c, defs.h: lint and gcc -Wall.
5046 Sun Dec 2 16:45:06 1990 John Gilmore (gnu at cygnus.com)
5048 Merge Intel 960 port of gdb, continuing...
5050 * dbxread.c (partial_symbol_file_open, partial_symbol_file_read,
5051 symbol_file_command): Pass from_tty arg to hush 'em up.
5053 * coffread.c (symbol_file_command): Avoid output if from_tty != 1.
5054 Add magic numbers for 960 COFF format.
5056 Fri Nov 30 09:18:20 1990 John Gilmore (gnu at cygnus.com)
5058 Merge Intel 960 port of gdb, from Intel "1.2" release.
5060 CHANGE_LOG entries from their port, which was based on
5063 Thu Sep 6 11:02:22 PDT 1990
5064 Remove temp file if download is interrupted.
5066 Wed Aug 1 09:08:33 PDT 1990
5067 Now uses binary protocol to talk to NINDY.
5068 Old hex protocol (NINDY 2.13 and older) supported with -O switch.
5069 Times out after 5 seconds when trying to talk to NINDY.
5071 Tue May 29 12:54:49 PDT 1990
5072 Added variable baud rate (-b switch).
5073 Source code reorganization.
5075 Thu Apr 26 11:09:55 PDT 1990
5076 More cleanup of batch mode; specifically, execute "-s", "-e", and
5077 "-se" switches as soon as they are encountered on the invocation line.
5079 Fri Apr 20 13:47:15 PDT 1990
5082 Thu Apr 19 09:54:28 PDT 1990
5083 Add 'reset' command.
5085 Wed Apr 18 09:48:07 PDT 1990
5086 After opening remote tty, wait for 1 second to go by without input
5087 from it before trying to talk to NINDY (fixes problems with the
5088 Heurikon HK80/V960E).
5090 Mon Apr 4 16:33:05 PDT 1990
5091 Some output was not being suppressed in 'batch' mode.
5093 Thu Mar 22 15:31:11 PST 1990
5094 Ask user if old symbol table should be deleted when new file is
5097 Allow user to run a program downloaded before gdb960 was brought up.
5099 Correct "exec-file" help message for i80960 context.
5101 Correct bug in calculating user space address: could occasionally
5102 corrupt user program.
5104 Make sure to zero low-order bits in rip's because of bug in 960CA
5105 A-step part: could cause operation faults when "next"ing across
5108 Correct bug that made it impossible to get source line numbers for
5109 code loaded at addresses higher than 0x7fffffff.
5111 Wed Jan 10 12:43:22 PST 1990
5112 Open remote tty for exclusive use.
5114 Fri Jan 5 12:14:42 PST 1990
5115 Correct disassembly (CA manual was right after all):
5116 opcode for sysctl is 0x659
5118 Mon Oct 23 12:03:04 PDT 1989
5119 Use G960BASE and G960BIN environment variables to find 'sx' utility.
5121 Mon Oct 16 14:15:09 PDT 1989
5122 "sfr0"-"sfr31" should have been named "sf0"-"sf31"
5124 Mon Oct 2 15:56:31 PDT 1989
5126 Added 960CA disassembly support.
5128 To simplify maintenance:
5129 - eliminated use of symblic links on pinsn.c: use i960-pinsn.c
5131 - eliminated opcode.h: incorporates tables into i960-pinsn.c
5132 - moved 960-specific routines from i960-pinsn.c to i960-md.c
5133 - made disassembly interface identical to that in gdmp960.
5137 Wed Nov 28 21:32:48 1990 John Gilmore (gnu at cygint)
5139 * target.h: Allow targets to stack. Add target_has_memory,
5140 _registers, etc. Restructure memory access and "info files"
5141 to walk the target stack.
5142 * exec.c, core.c, inftarg.c, remote.c, remote-vx.c, remote-eb.c,
5143 target.c: Change tables to match target.h.
5144 * inflow.c (child_mourn_inferior): pop child_ops.
5145 (generic_mourn_inferior): Use new has_stack flag.
5146 * infptrace.c (child_xfer_memory): New memory regime.
5147 * inftarg.c (child_files_info): New "info files" regime.
5148 * remote-eb.c: New memory regime, new info files.
5149 * remote-vx.c: New memory regime, new info files. Now use
5150 separate targets for VxWorks attachment to machine, and
5151 actually running a process under VxWorks, since one has
5152 stack & execution & regs and the other doesn't.
5153 * remote.c: New memory regime, new info files.
5154 * sparc-xdep.c (fetch_core-registers): New memory regime.
5155 * target.c: New routines and support for stacked targets,
5156 new memory regime, new info files regime.
5159 Generalize section handling for an arbitrary number of sections,
5160 including use of the new BFD (binary file) library.
5161 * gdbcore.h: Add struct section_table.
5162 * exec.c (build_section_table): Iterate all sections and
5163 record what gdb needs to know about them.
5164 (exec_command): Use it.
5165 (exec_xfer_memory): Use the table.
5166 (exec_files_info): Print the table.
5167 * core.c (core_file_command, core_xfer_memory, core_files_info):
5169 * source.c (find_source_lines): Use bfd_get_mtime.
5170 * dbxread.c: Quick changes to make it compile with new BFD.
5171 * utils.c (error): Avoid using bfd_error in generic routines.
5173 * core.c (core_fetch_registers): Get from the ".regs" section of
5175 * sparc-xdep.c (fetch_core_registers): Use the .regs info.
5177 * inferior.h (attach_flag): Export.
5178 * infcmd.c (run_command): use new target_create_inferior.
5179 * infrun.c (child_create_inferior): Don't return result.
5180 * Makefile.dist (VERSION): 3.91.4.
5182 Fri Nov 23 28:15:38 1990 John Gilmore (gnu at cygint)
5184 * breakpoint.c (bpstat_num): Handle breakpoints which have
5185 since been deleted, such as temporary breakpoints.
5186 infcmd.c (program_info): ditto.
5188 * core.c (core_file_command): Display the frame where the core
5193 * remote-vx.c (target_command): Merge in target command from
5194 targ-vx.c. A few other cleanups.
5196 * TODO, Projects: Lots more stuff to do...
5198 Fri Nov 23 18:15:38 1990 John Gilmore (gnu at cygint)
5200 Massive changes to wall off the remote-debugging interface
5201 behind a function vector. The port to handle VxWorks targets
5202 is also part of this.
5204 All files: Replace references to renamed functions,
5205 remove references to remote_debugging, remove references to
5206 have_include_file, have_core_file in favor of target_has_stack,
5207 target_has_memory, etc.
5209 * Modularize the breakpoint interface.
5210 breakpoint.h (BREAKPOINT_MAX): New define sets max length of
5211 a breakpoint instruction.
5212 breakpoint.c: struct breakpoint's shadow_contents now sized as
5214 (insert_breakpoints): Vector to target to install breakpoints.
5215 (remove_breakpoints): Vector to target here too.
5216 Remove REMOTE_SA_SPARC kludges and other remote_debugging.
5217 sparc-tdep.c (single_step): Use new breakpoint interface for
5218 the single-step breakpoints.
5219 mem-break.c (memory_insert_breakpoint, memory_remove_breakpoint):
5220 New file, contains routines to insert and remove breakpoints by
5221 reading out the old contents and later replacing them. This is
5222 how ptrace breakpoints work, and many remote systems as well.
5224 * tm-vxworks68.h: New config file, overrides a few things for
5225 Wind River's preferences.
5227 * target.h: New file, for transfer vector used to talk to the
5228 inferior (child, attached, core, exec, remote, etc). All accesses
5229 to the thing being debugged should come through these vectors.
5230 target.c: New file, routines to handle transfer vector.
5231 (various files): Add transfer vectors XXX_ops for the various
5232 targets and pseudo-targets (core files, etc) we support.
5234 * breakpoint.c (bpstat_stop_status): Further explorations of
5235 watchpoints and why things don't work all the time.
5236 (bpstat_alloc): New fn to allocate a bpstat and chain it.
5238 * config.gdb: Only add "source ${srcdir}/.gdbinit" to
5239 the local gdbinit if it doesn't already have it.
5241 * core.c (core_ops): add and install.
5242 Allow core debugging without exec file.
5244 * dbxread.c (free_and_init_header_files): Merge two fns.
5245 (end_symtab): Free named symbol table when a new version comes in.
5246 (read_dbx_symtab): Relocate all kinds of symbols with base
5247 address. First step toward handling different text, data, bss
5249 (add_file_addr_command): Renamed add_file_command.
5250 (add_file_command): Vector to remote handler.
5251 Add "load" as an alias for "add-file" command.
5253 * defs.h: Allow "volatile" to be used in non-ANSI; use it for
5254 non-returning functions.
5256 * exec.c: Add exec_ops, and push it as a target when an exec
5259 * infcmd.c (run_command): Pass executable file name and arg list
5260 separately when starting an inferior. Permit "run" when no exec
5261 file is specified, for VxWorks.
5262 (detach_command): Move to child_detach in inftarg.c.
5264 * inftarg.c: New file. Unix-child-specific routines, and the
5265 child_ops structure.
5267 * inferior.h (registers): Export "registers" as the way for
5268 target dependent register handlers to find gdb's local copy of
5269 the registers. Rename "stop_after_attach" to "stop_soon_quietly"
5270 since it is now used by places that want wait_for_inferior to
5271 handle the grunge but want to see every trap from the inferior.
5273 * inflow.c (create_inferior): Pull out, and merge into infrun.c.
5274 Eliminate remote_debugging hooks in terminal handling.
5276 * infrun.c: Replace start_inferior with child_create_inferior.
5277 Move all the hair of Unix shells and ptrace idiosyncracies into
5278 child_create_inferior, so remote handlers don't have to deal.
5279 Remove running_in_shell. Rename stop_after_attach to
5280 stop_soon_quietly, and use it in a few other places where we want
5281 to just call wait_for_inferior and get control back on the first
5282 trap. trap_expected now never takes a value > 1.
5283 (init_wait_for_inferior): Initialize static vars when a new
5286 main.c (gdbinit): Add new hook for .gdbinit file name, let
5287 it be overridden by config files as GDBINIT_FILENAME.
5288 (DEFAULT_PROMPT): Add new hook for overriding (gdb) prompt.
5289 Both of these are used for VxWorks gdb.
5291 mcheck.c: rename include file "gmalloc.c" to avoid problems
5292 with system include file "malloc.c".
5294 param-no-tm.h: New include file, same as param.h but does not
5295 include the default "tm.h" file. This is used in files where
5296 the target is known, e.g. remote-eb.c or sparc-xdep.c.
5298 param.h: Now just a shell that includes tm.h and param-no-tm.h.
5300 remote-vx.c: New file, VxWorks remote debugging support. Uses
5301 RPC routines that are shared with the target system, in directory
5304 remote.c: Vectorize remote interface.
5306 source.c: Globalize source_path, and make an alias "l" for "list"
5307 since we now have the "load" command.
5309 sparc-xdep.c: Use new param-no-tm.h.
5311 symmisc.c (free_named_symtab): Add new function from Wind River.
5312 However, ifdef it out for now while we think about what it should
5315 tm-sun3.h, xm-sparc.h, xm-sun3.h, xm-symmetry.h: Move
5317 the xm- file, and change its name to CHILD_PREPARE_TO_STORE, since
5318 non-Unix-children handle this with their own code in the target
5321 Makefile.dist: Roll version to 3.92.3. Add vx-share stuff to
5322 source and target lists. Add vx-share to default list of include
5323 directories. Add new files to src and target lists: mem-break,
5324 target, inftarg, remote-eb, remote-vx, targ-vx. Be sure the
5325 ${srcdir} versions of munch and createtags are used.
5327 * valops.c (find_function_addr): Split out of call_function.
5328 (call_function_by_hand): Rename call_function; this function
5329 calls functions in the target by laboriously patching the target
5330 word-by-word with the right stack, args, regs, etc.
5333 Mon Nov 5 17:29:10 1990 John Gilmore (gnu at cygint)
5335 Handle AMD 29000 a bit better.
5337 * remote-eb.c (readchar): Mask received char log to make it readable.
5338 (remote_start): Pass arguments down to executing program.
5339 Make startaddr unsigned.
5340 infrun.c (start_inferior): Accept args, pass them to
5342 infcmd.c (run_command): Pass args down to start_inferior.
5344 * tconfig/am29k-aout, tconfig/am29k-coff: New files specifying
5345 the target object file format.
5346 tm-29k.h: Pay heed to COFF_ENCAPSULATE.
5348 * am29k-pinsn.c (print_insn): Print 0x on hex numbers in disassembly.
5349 am29k-tdep.c (examine_prologue): Better checking of function prefixes.
5351 Sun Oct 7 18:20:45 1990 John Gilmore (gnu at cygint)
5353 * Makefile.dist (VERSION): Roll version to 3.91.9 and freeze.
5354 * TODO: We did a few things, we have more to do though.
5356 * xm-sparc.h (CLEAR_DEFERRED_STORES): Define.
5357 * inflow.c (inferior_died): Clear deferred stores.
5359 * Debug problems with dummy frames and calls to the inferior.
5360 * tm-sparc.h (PUSH_DUMMY_FRAME, POP_FRAME): Move to sparc-tdep.c.
5361 * sparc-tdep.c (do_restore_insn): Simplify.
5362 (sparc_frame_find_saved_regs): Simplify and fix what we find.
5363 (sparc_push_dummy_frame): Simplify and fix what we push.
5364 (sparc_pop_frame): Slightly more hair here, deciding whether
5365 we are restoring a saved PC or returning to a return address in %i7.
5366 * sparc-xdep.c (read_inferior_registers): Debug if valid reg is read.
5368 * utils.c (xmalloc, xrealloc): Return type depends on __STDC__.
5369 * symtab.h (xmalloc): ditto, for obstack_chunk_alloc.
5370 * obstack.h (chunkfun): ditto.
5371 * defs.h (xmalloc, xrealloc): ditto
5373 * utils.c (quit): Grab the terminal from the child if necessary.
5375 * inflow.c (term_status_command): Rename to term_info, change
5378 * sparc-pinsn.c (print_insn): Disassembly prefers real instructions.
5379 (is_delayed_branch): Speed up.
5380 * sparc-opcode.h: Add ALIAS bit to aliases. Fix up opcode tables.
5381 Still missing some float ops, and needs testing.
5383 * Support for input and output radixes other than base 10
5384 * defs.h (input_radix, output_radix): Declare.
5385 * expread.y (yyparse, parse_number): Handle changes of input
5386 radix, and ambiguous names-or-numbers in radixes >10.
5387 * printcmd.c (print_scalar_formatted): Print formatted hex
5388 numbers in varying column widths.
5389 * valprint.c (val_print): Use output_format to print scalar ints.
5390 (set_input_radix, set_output_radix, set_radix): Create.
5391 (set_output_radix): Set output_format from output_radix.
5392 (_initialize_valprint): add `set radix' but leave the others off.
5394 * main.c (execute_command): Let stupid questions be turned off.
5395 (_initialize_main): Handle "set stupidity", etc.
5397 * main.c, inflow.c, inferior.h, frame.h, command.c, defs.h,
5398 sparc-pinsn.c, sparc-xdep.c, value.h, valops.c, values.c: Lint.
5400 Tue Oct 2 11:20:02 1990 John Gilmore (gnu at cygint)
5402 * TODO, Makefile.dist, ChangeLog: Freeze for 3.91.8 release.
5403 bfd stuff is still screwed up, but with some manual work, it
5406 * breakpoint.c (bpstat_do_actions): Start over if a command
5407 proceeds the inferior, since the inferior will have stopped and
5408 will need to have its new stop-actions taken care of.
5410 * dbxread.c (read_struct_type): Expression gives Sun3 4.0.3
5411 compiler fits, simplify it.
5413 * gdb.texinfo (directory command): Doc new dir command.
5414 source.c (directory_command): "dir" now puts things on the front
5415 of the path, moves dups up front, and handles multiple names
5416 on the command line, inserting each one in order. It also
5417 blows away cached line and full_filename info.
5419 * stack.c (backtrace_command): Skip "more stack frames follow"
5422 * Change #ifndef HAVE_VPRINTF to #define MISSING_VPRINTF in
5423 xm-convex.h, xm-hp300bsd.h, xm-isi.h, xm-merlin.h, xm-news.h,
5424 xm-np1.h, xm-pn.h, xm-pyr.h, xm-symmetry.h, xm-umax.h, xm-vax.h.
5425 The only odd one was Gould NP1, which had defined vprintf to
5428 * Merge Ted Goldstein <tedg@Eng.sun.com>'s changes for epoch.
5429 printcmd.c (print_command_1): Pass 'inspect' flag down as a global
5430 variable, inspect_it.
5431 valprint.c (print_string, val_print): Use the global inspect_it
5432 to indicate whether to print in Epoch style or normal style.
5434 Mon Oct 1 23:55:26 1990 John Gilmore (gnu at cygint)
5436 * printcmd.c (call_command): add an alias for the "print" command
5437 which runs expressions and doesn't print the result if void.
5438 (print_command_1): implement it.
5440 * command.c: Remove #if 0'd code. Initialize all the fields
5441 in add_cmd (). Rename do_nothing_command to
5442 not_just_help_class_command, and make it externally visible.
5443 command.h: add user_commands to struct.
5444 * main.c (define_command): Don't overload c->function with a char
5445 string as well as a function pointer.
5447 * eval.c (evaluate_subexp): Reinstall tiemann changes to
5448 calling convention of value_struct_elt () that got dropped in
5451 * tm-sparc.h (FRAME_FIND_SAVED_REGS): move to sparc-xdep.c.
5452 sparc-tdep.c (sparc_frame_find_saved_regs): ditto.
5454 * tm-sparc.h (POP_FRAME): replace some constants with defines.
5456 * sparc-xdep.c (store_inferior_registers): defer stores to regs
5457 until a good time (e.g. when we are about to run the child),
5458 saving ptrace calls.
5459 * infrun.c (proceed): handle DO_DEFERRED_STORES.
5460 * tm-sparc.h: define DO_DEFERRED_STORES.
5462 * sparc-xdep.c (store_inferior_registers): when storing float
5463 registers, don't store stack regs too. When storing the SP,
5464 however, DO store the stack regs too. This fixes a bug in which
5465 the dummy frame is not recognized when a call_function finishes,
5466 because its frame pointer (in the stack regs) was never
5468 (read_inferior_registers): Mark WIM and TBR and FPS and CPS valid
5469 even though we don't know how to read them from an inferior.
5470 valops.c (call_function): Comment about storing SP.
5472 * infrun.c (save_inferior_status): Save away the original bpstat
5473 chain so it can be restored later. Install the copied version for
5474 use by whoever saved the status. It will be blow away by
5475 restore_inferior_status, and the original chain restored. This is
5476 important for people who have pointers into the original.
5478 * breakpoint.c, command.h, copying.awk, dbxread.c, defs.h,
5479 findvar.c, frame.h, obstack.h, obstack.c, inflow.c, value.h,
5480 main.c, printcmd.c, sparc-tdep.c, symtab.c, valprint.c: lint
5483 Fri Sep 28 20:32:46 1990 John Gilmore (gnu at cygnus.com)
5485 * Makefile.dist: Roll version to 3.91.8. Add bfd.h and bfdconfig.h
5486 temporarily to the makefile. Add am29k-opcode.h and WHATS.NEW.
5487 Add stuff.c and kdb-start.c to the OTHERS list for tar files.
5489 Fri Sep 28 19:12:12 1990 John Gilmore (gnu at cygint)
5491 * Merge Mike Tiemann's multiple inheritance changes from Sun.
5492 Store the baseclasses in a type struct starting from array element
5493 0 rather than from the unusual array element 1.
5495 dbxread.c: the above.
5496 (virtual_context): Add
5497 Read new debug information about which virtual function table
5498 a virtual function is from, and store it in fn_field.fcontext.
5500 symtab.h: Add fcontextt. Fix baseclass indices. Typo in
5501 TYPE_FN_FIELD_STATIC_P.
5503 symtab.c: the above.
5504 valops.c: the above. Handle pointer casts of object *'s.
5505 (search_struct_method): Add.
5506 (value_struct_elt): First arg is now a pointer to a value, and is
5509 valprint.c: the above.
5510 values.c (value_virtual_fn_field): Add type arg. Handle
5511 offsetting to the proper object when calling virtual fns.
5513 (baseclass_addr): Add valuep arg.
5515 * README: Document the current state of BFD config (missing).
5516 * TODO, ChangeLog, Makefile.dist: Roll version.
5517 * WHATS.NEW: Add summary of changes since 3.5.
5519 Thu Sep 27 16:23:12 1990 John Gilmore (gnu at cygint)
5521 * dbxread.c (read_struct_type): Clear bit vectors whenever
5523 symtab.c (B_CLRALL): define.
5525 * tm-sparc.h (STORE_RETURN_VALUE): Avoid clobbering types by
5526 using == rather than =. Huh... This fixes the dreaded problem
5527 wherein builtin_type_int becomes TYPE_CODE_FLT.
5529 * core.c (info_files): Show the inferior pid.
5531 * config.gdb: Avoid putting "dir" command into .gdbinit. GDB
5532 already knows how to look in the source directory.
5534 * Remove psymtab hair from many places. Remove duplicated code
5535 for searching symbol tables. Hide psymtabs from most places.
5536 Make it fast to get from a psymtab to its symtab.
5538 blockframe.c (blockvector_for_pc): Remove psymtab hair.
5539 coffread.c (psymtab_to_symtab): Rename to psymtab_to_symtab2.
5540 mipsread.c (psymtab_to_symtab): Rename to psymtab_to_symtab2.
5541 dbxread.c: export psymtab_to_symtab, make it work if called N times.
5542 (psymtab_to_symtab): Rename to psymtab_to_symtab2. Initialize
5543 new symtab completely. New psymtabs get symtab pointer
5544 initialized to zero. Remove MI warning printf.
5545 symtab.h: Comments. Add psymtab to symtab pointer.
5546 (PSYMTAB_TO_SYMTAB): New macro.
5547 symtab.c: use PSYMTAB_TO_SYMTAB. Add psymtab_to_symtab and export it.
5548 source.c: use PSYMTAB_TO_SYMTAB. Remove symtab version and
5550 stack.c (backtrace_command): Avoid pre-pass to read symbols, if
5552 (print_frame_info): Avoid special-casing symbols that have not yet
5555 * source.c (open_source_file): Quick path if we have already
5556 located the source file by its full name.
5558 * symtab.c (lookup_symbol): Use find_pc_symtab rather than
5559 find_pc_psymtab. When a name is found in the misc function
5560 vector, search the symbol table for its mangled name, not the
5561 name that the user typed.
5563 * bfd.h: Fix missing comment terminators, make #endifs match.
5565 * valarith.c (value_less): Handle unsigned int comparisons.
5566 Add FIXME about pointer compares, which assume host and target
5567 pointers are the same.
5569 * command.c (do_nothing_command): lint
5570 dbxread.c: lint. Remove sort_syms. Document C++ visibility info,
5571 fix comments on debug symbol format for visibility. Actually set
5572 visibility of symbols.
5573 main.c (echo_command): lint; use <readline/history.h>.
5574 tm-sparc.h (FRAME_FIND_SAVED_REGS): lint
5575 obstack.h (_obstack_blank): Rearrange pointer math to avoid
5576 pointing past end of allocated memory; saber complains.
5577 obstack.h: Declare the external functions that we use.
5578 valarith.h: use <string.h>
5579 solib.c (solib_add): lint.
5581 Fri Sep 21 17:05:19 1990 John Gilmore (gnu at cygint)
5583 * main.c (initialize_main): Default info_verbose to off, now that
5584 symbol reading is fast.
5585 (quit_command): Avoid clobbering exec_bfd while quitting.
5587 * Initial BFD (binary file diddling library) merger:
5588 coffread.c: Change AOUTHDR to struct exe_hdr.
5590 core.c: initialize initialized data at compile time.
5591 (core_file_command): Move from coredep.c, convert to bfd.
5592 (xfer_core_file): Convert to bfd.
5593 exec.c (exec_file_command): use bfd routines.
5595 mips-tdep.c: Remove exec_file_command and friends.
5598 * coredep.c: (fetch_core_registers) Convert core_file_command to
5599 fetch_core_registers.
5600 mips-xdep.c, sparc-xdep.c, sun3-xdep.c: ditto.
5602 * utils.c: (error): Bogus crap, FIXME, to print bfd errors.
5603 (my_bfd_read): More bogosity, which I don't think we call.
5604 (program_name): Remove this atrocity asap!
5606 Wed Sep 19 13:36:41 1990 John Gilmore (gnu at cygint)
5609 values.c: allocate_repeat_value was not clearing the
5610 optimized_out field.
5611 (value_static_field): minor stylistic fix (wrong macro was used).
5612 valops.c (value_struct_elt_for_address): didn't work for C++
5615 * signame.c (_initialize_signame): Initialize signal names once.
5617 * breakpoint.h, command.c, copying.awk, defs.h, environ.c,
5618 exec.c, frame.h, infcmd.c, inferior.h, main.c, munch, sun3-xdep.c,
5619 symtab.h, tm-29k.h, valprint.c, value.h, values.c: Lint.
5621 * remote-eb.c: Support user-settable baud rates on the serial port.
5623 * tm-sun3.h (PREPARE_TO_STORE): fix typo.
5625 Fri Sep 14 13:28:29 1990 John Gilmore (gnu at cygint)
5627 * tconfig/sun3os4: Remove warning about native assembler,
5628 since it also occurs in the xconfig file.
5630 * findvar.c (registers): Allocate some slop after `registers'
5631 to prevent stray accesses from trashing the next variable.
5633 * tm-68k.h (REGISTER_BYTES): Allocate the right number of bytes
5634 on the sun-3, by changing the #ifdef from `sun3' (which is not
5635 defined by cc) to `sun'. Symptom was trashed builtin_type_XXX
5636 vars, which happened to follow `registers' in the executable.
5638 * readline/history.c (history_search): Heed gcc-2's advice
5639 and parenthesize && inside ||).
5641 * am29k-opcode.h, am29k-pinsn.c, am29k-tdep.c, remote-eb.c,
5642 tm-29k.c: Insert FSF copyright headers.
5644 * remote-eb.c: Better comments.
5646 * Makefile.dist: Update to 3.91.6.
5647 * TODO: note PREPARE_TO_STORE problem.
5649 Thu Sep 13 09:52:33 1990 Jim Kingdon (kingdon at cygint)
5651 * stack.c (frame_info): Only use FRAME_FIND_SAVED_REGS if defined.
5653 * remote.c: Wrap the whole file in #if !defined (SPECIAL_REMOTE).
5655 * infrun.c (wait_for_inferior, at end): Don't set up
5656 prev_* if the inferior no longer exists.
5658 * inferior.h (CALL_DUMMY_LOCATION): New macro, to replace
5659 CANNOT_EXECUTE_STACK.
5660 valops.c (call_function): Use it.
5662 * tm-convex.h: Add CALL_DUMMY_LENGTH for use by PC_IN_CALL_DUMMY.
5664 * inferior.h (PC_IN_CALL_DUMMY): New macro.
5665 infrun.c (wait_for_inferior, 2 places): Use it.
5667 * values.c (value_being_returned): Only use
5668 EXTRACT_STRUCT_VALUE_ADDRESS if defined.
5670 * Move PREPARE_TO_STORE from xm-sun3.h to tm-sun3.h to do the
5671 right thing for remote-eb.c.
5673 * sun3-xdep.c: Remove extraneous call to remote_store_registers.
5674 * sun386-xdep.c, hp300hpux-xdep.c, sparc-xdep.c: Ditto.
5676 * blockframe.c: Put get_frame_saved_regs inside #if !defined
5677 (FRAME_FIND_SAVED_REGS).
5679 * findvar.c ({fetch,store}_registers): Check for
5680 REMOTE_{FETCH_STORE}_REGISTER macro.
5682 * findvar.c (get_saved_register): Add argument lval and
5683 change meaning of argument addr.
5684 findvar.c: Change calls to get_saved_register to reflect
5685 new calling convention.
5686 valops.c (value_assign): Use get_saved_register instead of
5687 find_saved_register.
5689 Sun Sep 2 12:40:20 1990 Jim Kingdon (kingdon at cygint.cygnus.com)
5691 * coffread.c (read_one_sym): Make temp_aux an AUXENT, not
5692 an (uninitialized) pointer to one. Use "&" when passing it
5695 Fri Aug 31 22:57:54 1990 Jim Kingdon (kingdon at cygint.cygnus.com)
5697 * coffread.c (getfilename): Use DGUX x_offset and x_name if
5700 * coffread.c (symbol_file_command): Put semicolon after
5702 Put safe_to_init_tdesc_context in #if defined (TDESC).
5703 Put #ifdef TDESCs in 1st column for non-ANSI cpp's.
5704 coffread.c: #include <sys/stat.h>.
5705 (read_coff_symtab): Typo: in_source_files -> in_source_file.
5706 Add missing ')' in check for "lc%" and friends. Remove
5708 Declare read_one_sym() at top of file.
5709 (read_file_hdr): Put in extra #ifdefs so MC68MAGIC and
5710 MC68WRMAGIC can have the same value without causing a duplicate
5713 Thu Sep 13 15:55:36 1990 John Gilmore (gnu at cygint)
5715 * Allow a Makefile to be built without building the
5716 tm and xm file links that screw up builds in subdirectories.
5717 This is done with `config.gdb none', then you can do things
5718 like `make gdb.tar.Z'.
5719 * tconfig/none: Config file for no target system
5720 * xconfig/none: Config file for no host system
5721 * config.gdb: If no TM or XM files are called out by the
5722 host or target file, don't make links for them.
5724 * cplus-dem.c: Add documentation.
5726 * dbxread.c (read_ofile_symtab): Turn a fatal error into a
5727 simple error, so the user's gdb doesn't crash due to some object
5728 file problem (e.g. somebody is rebuilding the file out from under
5731 * printcmd.c (print_address_symbolic): demangle the symbol.
5733 * Makefile.dist (OTHERS): Remove tdesc-lib because it has
5734 Motorola copyrights in it. Make "make gdb.tar.Z" work.
5735 (alldeps.mak): sort and uniq all results from this; duplicates
5736 hose gdb.tar.Z link building. Remove RCS files from
5737 tconfig and xconfig. Add config files for sun386. Add
5738 a few odd files to OTHERS and HFILES.
5740 Mon Sep 10 21:20:24 1990 John Gilmore (gnu at cygint)
5742 * Makefile.dist: Pull solib.c to tconfig/sun?os4.
5743 Roll version number to 3.91.5. Make lint work in bindir.
5745 * README: Document cross-debugging and new file structure.
5747 * blockframe.c: Lint. Include "value.h" to declare read_register.
5748 (find_pc_partial_function): remove duplicate line.
5750 * command.h: Lint. Declare error_no_arg and dont_repeat.
5752 * tm-news.h: Remove inadvertently duplicated stuff.
5754 * mipsread.c: Remove cache_pc_function stuff, now done cleanly.
5755 Clean up usage of misc_function_type. Declare some CORE_ADDRs.
5757 * config.gdb: Allow `config.gdb host target' form. Clean
5758 up previous change that printed bogus messages when you just said
5761 * core.c: #include "command.h" for lint.
5764 * main.c: Remove some casts of enums. Lint.
5771 * printcmd.c (initialize_printcmd): Fix thinko in inspect cmd.
5773 * sparc-tdep.c (isannulled): Take instruction as parameter, don't
5774 read it from memory. This will allow us to save ptrace calls
5775 eventually. Changed caller single_step too.
5777 * sparc-xdep.c (fetch_inferior_registers): Avoid reading regs
5778 that we aren't going to use, saving many ptrace calls, especially
5779 when watchpointing or single stepping. Use some #define's for
5781 (store_inferior_registers): Ditto.
5782 (core_file_command): Use some #define's for constants.
5784 * tm-sparc.h: Add #define's for some register numbers, so we
5785 can eliminate the use of random constants in sparc-xdep.c.
5787 * stack.c (frame_command, print_frame_info, up_command,
5788 down_command) Remove frame_changed, since it
5789 causes a bug and doesn't seem to do anything useful. In some
5790 places it was used as a flag, in others as a stack level (?).
5792 * utils.c: Use MISSING_VPRINTF rather than HAVE_VPRINTF, so the
5793 default is to use the portable (vprintf) version rather than the
5795 * xm-news.h (MISSING_VPRINTF): Add.
5797 * valprint.c (val_print): Demangle fancy vtbl printouts. Lint.
5799 Sat Sep 8 00:24:12 1990 John Gilmore (gnu at cygint)
5801 * Remove stuff that forces -Bstatic linking of gdb, and warnings
5802 about linking debugged programs -Bstatic in the sun?os4 config
5803 files in tconfig and xconfig subdirectories.
5805 * main.c (main): Remove unreached exit(0) now that we exit
5808 * Create TODO file for online bug list. There are too many
5809 "little" bugs to keep track of on paper.
5811 * Change Projects file to refer to bug-gdb@cygnus.com
5812 rather than kingdon@ai.
5814 Fri Sep 7 23:35:15 1990 John Gilmore (gnu at cygint)
5816 * Makefile.dist (VERSION): 3.91.4 now.
5818 * symtab.c (init_misc_bunches): Rename from init_misc_functions.
5819 (condense_misc_bunches): Add sanity check that misc_count is
5820 the same as the number of symbols in the bunch.
5822 * coffread.c: rename init_misc_bunches. Pass an argument
5823 to condense_misc_bunches (a zero).
5825 * dbxread.c (partial_symbol_file_read): Call init_misc_bunches
5826 every time we are called; don't rely on our caller to do it.
5827 (add_file): Remove call to init_misc_bunches.
5829 * mipsread.c: Only warn, don't error, if unknown symbol types.
5830 This keeps an old gdb from falling on its face if it sees newly
5831 extended symbol info. Rename init_misc_bunches.
5833 Fri Sep 7 22:58:15 1990 John Gilmore (gnu at cygint)
5835 * Merge in changes from Per Bothner for DECstations and other
5836 MIPS stuff. The rest is Bothner speaking:
5838 The next message is a merger of Alessando Forin's mips port with
5839 mine. I've tried to use my good if biased judgment to get
5840 the best of both. It *does* need testing.
5842 Some of the changes are general, *not* mips-specific.
5845 Didn't believe in little-endian bit order.
5846 There are still inconsistencies about whether flags
5847 like BITS_BIG_ENDIAN are integer (#if ...) or
5848 boolean (#ifdef ...). I tried to paper over them.
5850 dbxread.c,coffread.c,mipsread.c,symtab.c,symtab.h:
5851 Moved some misc_function code that was common to
5852 {dbx,coff,mips}read.c to symtab.c.
5853 In the process, I think I cleaned things up a bit.
5854 At the same time, moved obsavestring and obconcat to symtab.c.
5857 Removed obsolete condense_addl_misc_bunches (use
5858 condense_misc_bunches(1) instead).
5861 Needed to include <sys/dir>, at least on DECstations.
5863 valops.c, mips-tdep.c, tm-mips.h:
5864 Added PUSH_ARGUMENTS macro to support funny argument-pushing
5865 conventions (when STACK_ALIGN is insufficient).
5866 Needed on mips, where doubles need 8-byte alignment,
5867 but ints only need 4.
5870 Removed cruft that was not being used.
5871 Merged in many fixes (most from Frank Yellin, fy@lucid.com).
5874 Print $ before register-names (I think that makes things a little
5876 Never print two instructions, even if one delays.
5877 Removed hex-disassemble set_cmd. (This is not mips-specific,
5878 so I think the argument is whether it is generally worthwhile or not.
5879 I'm inclined to think not, given how easy it is to
5880 convert between radixes in gdb.)
5883 This is basically Alessando's code.
5884 It doesn't use obstacks; I changed it to use obstacks
5885 in a few minor places where using malloc causes a
5886 memory leak. (Probably, more places could/should be changed.)
5887 I added record_misc_function where it was missing.
5888 In symbol_file_command and add_file_command, I tried
5889 to make the code consistent with more recent versions.
5890 Minor sylistic changes in parse_procedure.
5891 Make a .gdbinfo. psuedo-symbol point back to the real
5892 procedure symbol (using the isym field).
5895 This is basically from my port, but with a lot of details
5896 and a number of routines merged in from Alessando's version.
5897 I basically used my code "raw" backtrace (use heuristics
5898 from the actual code, rather than symbol table info) - though
5899 the idea is Alessandro's. I feel my code is a little cleaner
5900 here, particularly in being a little more flexible, such as being
5901 able to handle gcc-produced code (which it now can).
5902 It also doesn't do frame caching (which is not useful
5903 more recent gdb versions).
5904 I also used my code for push_/pop_dummy, more or less.
5905 I tried to incorporate AF's code for testing sigtramp
5906 while backtracing; I probably got it wrong.
5907 Added mips_print_register, which tries to scrunch as much
5908 information as possible on a screen...
5909 Removed the skip-prologue set_cmd. As with hex-disassemble (see
5910 under mips-pinsn.c), I don't see anything mips-specific here,
5911 and I don't see it being all that useful anyway.
5914 Added a $fp psuedo-reg distinct from $fp (nice for gcc).
5915 Use more register names (rather than hard-cases numbers).
5917 Thu Sep 6 18:33:15 1990 John Gilmore (gnu at cygint)
5919 * Hack up 3.90.11 changes:
5921 * Makefile.dist (depend): parameterize $(GCC).
5922 Add solib.c and solib.o.
5923 (readline): Fix vpath for both absolute or relative SRCDIR.
5925 * blockframe.c: Fix from Schaefer@asc.slb.com for shared libs.
5926 Also, let the part I didn't understand at least compile so
5927 I can test the rest. FIXME.
5929 * dbxread.c: Fix thinko using strcmp.
5930 (init_psymbol_list): declare static.
5931 (partial_symbol_file_open): Comment cleanups better, avoid
5932 cleaning up the string table since the caller will do that.
5933 Move the stat for mod time into symbol_file_command, temporarily.
5934 (There should be a mod time for each symbol file, eventually,
5935 to control its rereading. FIXME.)
5937 * infptrace.c (PT_WRITE_D): use same value as PT_WRITE_I for
5938 SunOS, which gives error for shared libs otherwise. (From
5939 Schaefer, probably FIXME needs work for portability.)
5941 * solib.c: Move #include "param.h" to work.
5942 Lowercase all the Uppercase Letters In the Messages.
5943 (find_solib): Clean up inferior_so_name for debug printouts.
5944 Allow no argument, to mean all shared libraries.
5946 * symmisc.c: include param.h to get CLEAR_SOLIB.
5948 Wed Sep 5 18:00:08 1990 John Gilmore (gnu at cygint)
5950 * Merge in Kingdon's changes from FSF: the diffs from 3.90.9
5951 to 3.90.11. ChangeLog entries below are from this.
5953 Wed Jun 13 09:17:39 1990 Jim Kingdon (kingdon at mole.ai.mit.edu)
5957 * Makefile.dist (HFILES): Add tm-sunos.h.
5959 Tue Jun 12 16:15:26 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5963 * Makefile.dist (gdb.tar.Z): Change linking of config so it works.
5965 Thu Jun 7 16:22:27 EDT 1990 Jay Fenlason (hack@ai.mit.edu)
5967 * sparc-opcode.h Added single-operand version of rett.
5969 Mon Jun 4 18:12:31 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5971 * m-sparc.h (REG_STRUCT_HAS_ADDR, STRUCT_ARG_SYM_GARBAGE):
5972 Put parens around gcc_p in expansion.
5974 Thu May 24 15:44:51 1990 Jim Kingdon (kingdon at mole.ai.mit.edu)
5976 * utils.c (lines_to_list): Return 10 if lines_per_page == 0.
5978 Wed May 23 16:36:04 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5980 * Changes for Sun shared libraries:
5981 blockframe.c (find_pc_partial_function): If a non-text symbol
5982 is found, set *address = pc - FUNCTION_START_OFFSET.
5983 breakpoint.c (insert_breakpoints) [DISABLE_UNSETTABLE_BREAK]:
5984 Disable breakpoints instead of giving an error.
5985 source.c (select_source_symtab): Initialize cs_pst.
5986 symmisc.c: Call CLEAR_SOLIB if defined.
5987 symtab.h: Make text{low,high} CORE_ADDR not int.
5988 (psymtab): New field addr.
5990 dbxread.c: Move DECLARE_FILE_HEADERS outside functions.
5991 (record_misc_function): Give correct type for N_DATA symbols.
5992 (condense_misc_bunches): do "misc_function_count = j" regardless
5994 Take code which is shared between symbol_file_command and
5995 add_file_command and put it into partial_symbol_file_{open,read}.
5996 Split add_file_command into add_file_command and add_file.
5997 Make psymtab_to_symtab read in the string table if the file
5999 Two new parameters to read_dbx_symtab and start_psymtab.
6000 tm-sunos.h: New file.
6002 Tue May 22 17:43:03 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
6004 * infcmd.c: Change cont_command to continue_command and "cont"
6007 Mon May 21 14:41:41 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
6009 * breakpoint.c (enable_breakpoint): Get value of watchpoint.
6011 * defs.h [sparc]: Use <alloca.h> regardless of __GNUC__.
6013 * values.c (USE_STRUCT_CONVENTION): Check for structures of
6014 size 1,2,4,8 rather than size < 8.
6016 * dbxread.c (dbx_lookup_type): Do f->length *= 2 as many times
6017 as necessary, not just once.
6019 * sparc-opcode.h: Add a bunch of new opcodes which Sun as supports.
6021 Thu May 17 15:04:09 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
6023 * {t,x}m-sun386.h, sun386-xdep.c, {x,t}config/sun386
6025 * tm-news.h: Add CALL_DUMMY_*.
6027 * tm-68k.h: Remove duplicate comment at FRAME_FIND_SAVED_REGS.
6029 * config.gdb: In list_host, list_target, use ${i}, not $i.
6031 Tue May 15 21:27:12 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
6033 * source.c (find_source_lines) [BROKEN_LARGE_ALLOCA]: Use xmalloc.
6035 * sparc-opcode.h: Change all store floating-point state register
6036 instructions to have the right match & lose fields.
6038 Sat May 5 12:39:18 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
6040 * Makefile.dist: Move -I${srcdir} to GLOBAL_CFLAGS and pass
6042 config.gdb: If srcdir != ., create readline directory and
6043 copy a makefile into it.
6045 * wait.h, infrun.c: Change WRETCODE to WEXITSTATUS for
6046 consistency with POSIX.
6048 * breakpoint.c (bpstat_stop_status): Disable watchpoint
6049 when we exit its exp_valid_block.
6051 Tue Sep 4 11:46:46 1990 John Gilmore (gnu at cygint)
6053 * Makefile.dist: Bump version to 3.91.3.
6055 * Clean up handling of breakpoint commands (somewhat).
6056 Prompted by Tiemann bug report "cont 10" doesn't work any more.
6058 inferior.h: Add breakpoint_proceeded to inferior status struct
6059 and globals; save it and restore it.
6060 (clear_breakpoint_commands): Cleanup, remove old #define.
6062 infrun.c (clear_proceed_status): Set breakpoint_proceeded.
6063 (save_inferior_status, restore_inferior_status): handle it also.
6064 (proceed): Remove earlier code that set breakpoint_proceeded.
6065 It is now set only in clear_proceed_status.
6066 (clear_proceed_status): Cleanup, use bpstat_clear rather
6067 than clear_breakpoint_commands. No callers need the stop_bpstat
6068 between clear_proceed_status and proceed.
6070 infcmd.c: Add breakpoint_proceeded definition and comment.
6071 (cont_command, jump_command, signal_command): Move call to
6072 clear_proceed_status right next to call to proceed.
6074 breakpoint.c (bpstat_do_actions): Avoid clobbering our
6075 caller's argument while running down the chain of breakpoints.
6076 Use new variable "breakpoint_proceeded" to determine when
6077 a command that it executes moves the inferior past the
6079 (bpstat_clear): Handle NULL argument.
6080 (bpstat_clear_actions): Avoid useless call to
6081 breakpoint_auto_delete.
6082 (delete_breakpoint): Clean up bpstat's that are pointing to
6083 the deleted breakpoint from the stop_bpstat chain.
6084 (breakpoint_auto_delete): Simplify.
6086 * Clean up handling of EOF, error on stdin, etc. This was
6087 prompted by a network problem that caused gdb to go into an
6088 infinite loop filling up its malloc'd memory.
6090 main.c (return_to_top_level): Cleanup: call bpstat_clear_actions,
6091 not clear_breakpoints_commands, which is now gone.
6092 (main): If command_loop returns (e.g. from EOF on stdin), do
6093 a quit_command (looping back to command_loop if quit_command
6094 doesn't really quit).
6095 (command_loop): check result from command_line_input and
6096 exit if it returns NULL, rather than passing the NULL to
6098 (gdb_readline): Free malloc'd result space before returning
6101 * utils.c (query): Handle C-d to mean "yes", just as if the
6102 input was not a terminal. Also avoid infinite loop if EOF
6103 occurs in mid-input-line before newline. This allows
6104 query to be used at EOF on stdin with reasonable results.
6106 * infrun.c (proceed): Set breakpoint_proceeded.
6108 * values.c (value_as_long): Avoid infinite recursion for enums.
6109 (_initialize_values): Fix typo in help msg (kingdon).
6111 * Makefile.dist (RL_LIB): Use RL_LIB_DEP for dependencies,
6112 RL_LIB for linking. This allows -lreadline for linking
6113 and nothing for dependencies, once readline is a real library.
6115 * config.gdb: Jim Kingdon: give useful error message if the
6116 host or target type is not recognized.
6118 * defs.h (alloca): SPARC <alloca.h> does not declare alloca,
6119 it just defines it. Dumb, but deal with it.
6121 * Jim Kingdon suggests:
6122 in xconfig/sun3os4, CFLAGS should be XM_CFLAGS.
6124 Wed Aug 29 18:03:27 1990 John Gilmore (gnu at cygint)
6126 * Makefile.dist (VERSION): Bump version # to 3.91.2.
6128 * Clean up Bothner's changes.
6130 * blockframe.c (clear_pc_function_cache): New function.
6131 * blockframe.c: remake cache_pc_function_* static.
6132 * dbxread.c (symbol_file_command): remove references to
6133 cache_pc_function_* variables.
6134 * dbxread.c (read_struct_type): Use VOFFSET_STATIC.
6135 * printcmd.c: Avoid kludging a global variable (addressprint)
6136 to avoid printing the address of a string twice. Instead,
6137 pass the format letter 's' down low enough that it can be seen
6138 to avoid this problem.
6139 (print_formatted): Pass format arg to value_print.
6140 (restore_addressprint): Remove function.
6141 (do_examine): Avoid hacking addressprint, cleanups and such.
6142 (print_frame_args): Add a comment to a Bothner change.
6143 * symtab.h: define VOFFSET_STATIC and use it instead of "-1".
6144 * symmisc.c (free_all_symtabs): Call clear_pc_function_cache
6145 to wipe out the values cached in blockframe.c.
6146 * symtab.c (find_method): Add comment saying how big you must
6147 allocate to be "big enough". Per being terse again.
6148 * valprint.c (val_print): Handle format letter "s" to print
6149 strings without addresses. Add comment to vtbl printing code
6150 which casts with wild abandon. Rearrange reference-printing
6152 @0xaddr: value (print w/addressprint)
6153 value (print w/~addressprint)
6154 @0xaddr (parameter lists w/addressprint)
6155 or nothing (parameter lists w/o addressprint)
6157 Tue Aug 28 10:47:18 1990 John Gilmore (gnu at cygint)
6159 * Merge more changes from Per Bothner:
6161 Gdb's handling of TYPE_CODE_REF was so counter-C++ (and otherwise
6162 annoying) that I tried to improve it. Here are my suggestions.
6164 These patches all attempt to handle TYPE_CODE_REF (as in C++) better.
6167 Do automatic de-reference when taking the address of a reference.
6169 Don't deref_ref when printing parameter lists.
6171 More attempts at treating refernences properly.
6173 In val_print, if deref_ref==0, don't print dangling " = ".
6175 Add COERCE_REF macro, which de-references an REF.
6177 * Merge changes from Per Bothner:
6179 * Fixed (Sony news)-specific configuration problems.
6180 * Fixed other problems with using vanilla pcc and libc (enum problems;
6181 assumption that vsprintf exists).
6182 * Some major speed-ups (finc_pc_partial_function now caches a match;
6183 parsing avoids duplicate symbol_lookup calls).
6184 * Changed handling of baseclasses (no longer use baseclasses field
6185 of struct type, use the first n_baseclasses fields instead).
6186 * Various minor changes/fixes, most C++-related.
6189 Cache the most previous match from find_pc_partial_function.
6190 (Save both low and high ends of matching function's pc range.)
6191 This speeds up the loop of infrun.c:wait_for_inferior quite
6192 a bit, and makes step/next commands much zippier.
6194 Added an enum->int cast (otherwise, some compilers barf).
6196 No longer set baseclass offset to 0, since multiple
6197 inheritance now mostly works.
6198 Added a number of casts, to shut up compiler warnings
6199 (after stabs where made enums, not ints).
6200 When discarding a symbol table (in symbol_file_command),
6201 must clear the cache introduced in blockframe.c.
6202 Don't convert $vtbl_ptr_type to vtbl any more.
6203 Get rid of TYPE_BASECLASEES and baseclass_vec (see also symtab.h).
6204 Mask off sign bit emitted by g++ for virtual table offset.
6205 Set voffset to -1 (not 1) for static member functions.
6207 Changed parsing/lexing of names to avoid doing symbol lookup twice
6208 (once when lexing to determine symbol class, once for real).
6209 Now only call symbol_lookup once. Fields of 'this' win especially big.
6211 Subpress printing addr twice in the case of 'x/s addr'.
6213 lookup_basetype_type is no longer used.
6214 Add find_methods as recursive helper function to decode_line_1.
6215 This allows multiple inheritance to work.
6216 Also, once one or more matches has been found, do not look in
6217 base-classes. (Baseclass methods would be overridden, anyway.)
6219 Removed baseclasses array in struct type.
6220 Instead of using baseclasses[i], use fields[i-1].
6221 Added virtual_field_bits[i] to indicate if the i'th baseclass is virtual.
6222 Changed sign convention of voffset (previous was inconsistent).
6224 Some macros (CALL_DUMMY and relatives) were missing. Put them back.
6226 Used to assume existence of vsprintf. Re-written to not need it
6227 if HAVE_VPRINTF is undefined.
6229 typecmp was too pessimistic. Made it less so.
6231 Don't print space after address.
6232 If vtable points to a misc symbol (with 0 offset), print it,
6233 since that indicates the actual class of the object.
6234 Changed ype_print_derivation_info to use new inheritance
6235 scheme (without baseclasses vector).
6237 In value_primitive_field, fixed some bugs left over from previous set of fixes.
6238 Also, changes needed because TYPE_BASECLASSES were removed.
6240 REGISTER_U_ADDR didn't work for PC. Rewrote to use an array.
6242 Tue Aug 21 20:08:54 1990 John Gilmore (gnu at cygint)
6245 If there is no path set, and the symbols don't indicate what directory
6246 a file was compiled in, look in the current directory. But either
6247 a path or a known compilation directory will prevent this.
6250 Three independent bug fixes:
6251 * Remove the #if 0 block that breaks some stuff.
6252 * SunOS 4.1 fixed the promoted-parameter-wrong-addr bug in Sun C;
6253 adapt gdb to either SunOS 4.0.* or 4.1.
6254 * MAX_OF_TYPE and MIN_OF_TYPE thinko. By tedg@sun, I think.
6257 Instantiate the class T when looking for methods in it. (Tiemann@sun)
6260 (type_print) Demangle the name being printed.
6261 (type_print_base) Handle botched demangling without coredump (tiemann).
6264 (check_stub_method): Document routine.
6265 (tiemann) fix bug for no-arg functions
6266 Avoid clobbering beyond end of malloc'd storage.
6267 Terminate the argument list properly.
6269 Sat Aug 18 01:29:59 1990 Per Bothner (bothner@cs.wisc.edu)
6271 * Changes merged by John Gilmore:
6274 In breakpoint_1, use new print_address_symbolic instead
6275 of find_pc_partial_function. (This forces use of assembler-level
6276 addresses, and avoids misleading non-mangled source-level names.)
6278 Generalize ansi argument such that -1 means skip arglist totally.
6279 Removed global variable print_ansi_qualifiers (which made
6280 code non-reentrant), in favor of extra explicit arguments
6281 to internal routines.
6283 Add new helper function print_address_symbolic.
6284 Use find_pc_misc_function instead of find_pc_partial_function
6285 (since we want assembler-level symbols here).
6287 Print unknown function as just "f (...)", not "f (...) (...)".
6288 Use new fputs_demangled explicitly.
6290 Fixed a typing violation (problem: value.h cannot be imported
6291 without renaming many variable in this file).
6292 lookup_symbol: If no matching misc_func, look for a C++-mangled name.
6293 decode_line_1: Moved forward some never-reached code.
6294 Made decode_line_2 skip function prologues correctly.
6296 fputs_filtered should not demangle by default.
6297 Add new fputs_demangled to demangle on demand..
6299 Change value_struct_elt to use value_primitive_field (using recursive
6300 utility function search_struct_field). This allows foo.bar to work
6301 for multiple inheritance (so far only for data fields).
6302 Change check_field in the same way (recursive helper function
6303 to support multiple inheritance).
6304 (Note: there are more of these problems that I haven't fixed.
6305 Any code that says TYPE_BASECLASS (t, 1) is probably wrong.)
6306 value_of_this: 'this' symbol name is now just "this", note "$this".
6308 Don't print static members.
6309 Avoid printing "members of <type>" if there are none.
6310 Simplified type_print_derivation_info by merging duplicate code.
6311 Remove useless blank lines in type_print_base (ptype command).
6313 Added declaration of new routine value_primitive_field.
6315 Added value_primitive_field which is generalized version of
6316 value_field that can handle multiple inheritance (non-zero offsets etc).
6317 Re-implemented value_field to call value_primitive_field.
6319 Fri Aug 17 23:33:44 1990 John Gilmore (gnu at cygint)
6321 * infcmd.c -- insert else to avoid 'delete env' coredump when you
6322 delete the whole environment. Karl Berry reported the bug.
6323 * source.c - fix openp to avoid //'s in filenames, which
6324 trigger an Emacs bug causing it to not be able to find files
6325 when running gdb in a window.
6326 * dbxread.c - zap the #if 0 that botches the add-file code.
6327 It seems to work a lot better without all the code commented out.
6329 Fri Jul 20 16:58:46 1990 John Gilmore (gnu at cygnus.com)
6331 * Merge Tiemann's and Ted Goldstein's changes, detailed below,
6334 Tue Jul 17 19:34:33 1990 Ted Goldstein (tedg at golem)
6336 * Makefile - added a ${CFLAGS} to a couple of entries,
6337 added remote-sa.sparc.c
6338 * added remote.sa-sparc.c, a modification of remote.c
6339 which conducts a dialog directly with the SparcStation prom.
6340 * breakpoint.c, infrun.c, sparcdep.c added
6341 remote_insert_breakpoint(), and remote_remove_breakpoint()
6342 to breakpoint.c instead of directly writing breakpoint instructions.
6343 * sparcdep.c on remote_debugging,there is no need
6344 to remove signle step breakpoint instructions.
6345 * main.c added "-epoch" flag and "int epoch_interface" to main.c
6347 * printcmd.c - epoch interface sends lisp expressions to open up
6348 epoch windows on inspection.
6349 * valprint.c - added arrayprint, and addressprint and made adding
6350 format controls easier
6351 * wait.h added a couple of undef's because we were getting
6352 complaints about WSTOPSIG and WTERMSIG begin redefined.
6355 Wed Jul 4 05:27:51 1990 Michael Tiemann (tiemann at masham)
6357 * symtab.c (decode_line_1): Add support for handling method stubs
6358 in the type information.
6360 Tue Jul 3 09:39:18 1990 Michael Tiemann (tiemann at masham)
6362 * values.c (baseclass_addr): Run loop from INDEX+1 to
6363 N_BASECLASSES; otherwise, we can still get into a loop.
6364 @@ This should be restructured to use a cleaner search strategy.
6366 Sun Jul 1 12:28:51 1990 Michael Tiemann (tiemann at masham)
6368 * dbxread.c (define_symbol,read_type): Grok GNU C++'s new
6369 abbreviation "Tt" for tags which have the same name as their
6372 Fri Jun 29 01:03:46 1990 Michael Tiemann (tiemann at masham)
6374 * symtab.c (list_symbols): add ability to set breakpoints on all
6375 the functions which match a particular regular expression.
6377 Tue Jun 26 04:26:29 1990 Michael Tiemann (tiemann at masham)
6379 * cplus-dem.c (cplus_demangle): New parameter ANSI says whether we
6380 should print ANSI qualifiers (such as `const' and `volatile').
6381 All callers changed to call with ANSI == 1, except from
6382 `check_method_stub', which uses old-style syntax.
6384 * symseg.h (struct fn_field): Remove unneccessary `args' field.
6385 * symtab.h (TYPE_FN_FIELD_ARGS): Redefined.
6387 * values.c (check_stub_method): New function.
6389 * cplus-dem.c (do_type): Handle "long long" (encoded as 'x').
6391 * dbxread.c (read_type): Handle new GNU C++ method type stubs.
