1 Fri Nov 22 16:39:57 1991 John Gilmore (gnu at cygnus.com)
3 * inflow.c (terminal_inferior): Check the results of ioctl's, and
4 print a message if any of them fail.
5 (terminal_ours_1): Store result of ioctl's for debugging, but
6 don't print (the terminal isn't ours...).
8 * tm-tahoe.h (FRAME_ARGS_ADDRESS): No need to offset from frame
11 * m2-exp.y (MAX, MIN): Rename to MAX_FUNC, MIN_FUNC to avoid
12 conflicts with system header files.
14 Fri Nov 22 08:27:40 1991 John Gilmore (gnu at cygnus.com)
16 * Roll VERSION to 4.2.95.
18 * buildsym.c, coredep.c, mem-break.c, xcoffread.c: Put <stdio.h>
20 * config/mh-i386sco: Override compiler to gcc, print warning.
21 * configure.in: Handle i386-none-aout rather than i386-aout-none.
22 * infptrace.c, language.h, utils.c: Lint.
23 * m2-exp.y: #undef MAX and MIN in case system includes set them.
24 * xm-tahoe.h: Set HOST_BYTE_ORDER. Include system versions of
25 {BIG,LITTLE}_ENDIAN and the INT_MAX family first, to avoid
26 redefinition warnings.
27 * defs.h: Reorder things so that the xm-file gets first crack
28 at #define's, followed by defs.h and then the tm-file.
29 * Makefile.in: Remove spaces after 'ignore exit code' - flags.
30 Late-model BSD 'make's don't cope with them.
32 Thu Nov 21 23:48:56 1991 John Gilmore (gnu at cygnus.com)
34 * Makefile.in: Roll new files into various lists.
36 Thu Nov 21 18:26:11 1991 Fred Fish (fnf at cygnus.com)
38 * dwarfread.c (struct_type): Must initialize the c++ specific
39 portion of union types as well as struct types, since gdb attempts
40 to reference the c++ specific info for both types.
42 Thu Nov 21 10:23:52 1991 John Gilmore (gnu at cygnus.com)
44 * Makefile.in: Roll VERSION to 4.2.90.
46 * defs.h: Incorporate param.h into defs.h. All users changed.
47 * param-no-tm.h: Change users to define TM_FILE_OVERRIDE instead.
48 * param.h, param-no-tm.h: Removed.
49 * Update copyrights in all changed files.
50 * dbxread.c, dwarfread.c, inflow.c, infrun.c, m2-exp.y, putenv.c,
51 solib.c, symtab.h, tm-umax.h, valprint.c: Lint.
52 * tm-convex.h, tm-hp300hpux.h, tm-merlin.h, tm-sparc.h,
53 xm-merlin.h: Avoid host include files in target descriptions.
54 * getpagesize.h: Removed, libiberty copes now.
55 * Makefile.in: Remove getpagesize.h, param.h, param-no-tm.h.
57 * exec.c (exec_files_info): If `verbose' is set, show file offset

61 * standalone.c: Fake getcwd rather than getwd.
62 * xm-*.h: Remove fake values of MAXPATHLEN.
64 * xcoffexec.c: Add /* */ to #if 0'd thing to help ANSI.
66 Wed Nov 20 18:35:56 1991 John Gilmore (gnu at cygnus.com)
68 * Remove gdb/hp-include. Support for HP a.out oddities should be
69 in BFD, not in GDB. Move gdb/hp-include/a.out.h to include/a.out.hp.h.
71 * infptrace.c, tm-sun386.h: Cashier <a.out.gnu.h>, remove refs.
73 * configure.in, xconfig, tconfig, Makefile.in, doc/gdbint.texinfo:
74 Makefile fragments for various hosts and targets now come from
75 gdb/config/mh-* and gdb/config/mt-*. This is for consistency with
78 * rs6000-pinsn.c, rs6k-opcode.h: Clean up.
79 * rs6k-opcode.def: Delete.
81 Wed Nov 20 05:04:40 1991 Fred Fish (fnf at cygnus.com)
83 * dwarfread.c: Recognize obsolete form of AT_element_list
84 attribute still used by at least one AT&T compiler, and possibly
87 Tue Nov 19 07:53:55 1991 Fred Fish (fnf at cygnus.com)
89 * dwarfread.c (enum_type, struct_type): Ignore names invented by
90 helpful compilers for anonymous structs, unions, and enums.
92 * c-exp.y, m2-exp.y: Add defines for yymaxdepth, yy_yys, and
93 yy_yyv, so multiple parsers produced by SVR4 versions of yacc
94 can coexist in the same executable without collision.
96 * symtab.h: Add declaration for lookup_template_type() to kill
97 compiler warnings about conversions from int to pointer.
99 Mon Nov 18 17:45:18 1991 Fred Fish (fnf at cygnus.com)
101 * procfs.c: Move inclusion of defs.h to before param.h, as in
102 all the other source files that include both. This is required
103 to supply some typedefs that are used in files included by param.h.
105 * m68k-tdep.c (m68k_skip_prologue): Add generic m68k support for
106 skipping function prologues, ala the other cpu families (i386,
107 mips, m88k, etc). Add the ability to skip movm and fmovm
108 instructions in the prologues. Still needs support for profile
109 (-p compiled) prologue sequences (FIXME).
111 * tm-68k.h: Change SKIP_PROLOGUE macro to use the new generic
112 m68k prologue skipping function by default.
114 * tm-altos.h, tm-isi.h: Continue to use the old definition of
117 Mon Nov 18 15:12:45 1991 John Gilmore (gnu at cygnus.com)
119 * Makefile.in: Remove tdesc stuff, and extra blanks before colons.
120 * blockframe.c: Remove tdesc-related code. Default
122 * infrun.c: Remove tdesc-related code.
123 * m88k-tdep.c (frame_chain_combine, init_frame_pc): Remove copies
124 of defaultable things.
125 * tm-m88k.h: New file, common to all Moto 88k target configs.
126 Derived from tm-delta88.h.
127 * tm-delta88.h: Use it.
128 * xm-m88k.h: Common file for 88K hosts. Remove obsolete stuff.
129 * xm-delta88.h: Use it.
130 * tm-*.h: Remove FRAME_CHAIN_COMBINE macros, since all are
132 * coffread.c: Remove tdesc stuff.
133 * tconfig/delta88, tconfig/m88k: Remove tdesc stuff.
134 * xconfig/m88k: Rename tm-88k.h to tm-m88k.h.
136 Mon Nov 18 13:51:37 1991 Per Bothner (bothner at cygnus.com)
138 * source.c (open_source_file): If openp fails, try again
139 using just the base (non-directory) part of the filename.
140 This solves various annoying problems, such as when the
141 source was compiled with an absolute pathname - and the
142 source files have moved. Or if the source was compiled
143 using a relative pathname, it can be more convenient
144 to just specific the source directory to the dir command.
146 Mon Nov 18 00:04:41 1991 Fred Fish (fnf at cygnus.com)
148 * cplus-dem.c (munge_function_name): Add missing third arg to
149 instance of call to do_type().
151 * dwarfread.c: Changes to match new dwarf.h. Remove
152 AT_deriv_list, AT_loclist, AT_incomplete, AT_const_data,
155 Sun Nov 17 16:20:53 1991 Michael Tiemann (tiemann at rtl.cygnus.com)
157 * symtab.h (struct type): Moved C++-specific fields into new type
158 `struct cplus_struct_type'. Now takes 10% less memory. Many
160 * symtab.c (init_type): Don't set fields belonging to
161 TYPE_CPLUS_SPECIFIC unless TYPE is TYPE_CODE_STRUCT.
162 * buildsym.c (read_type): Allocate TYPE_CPLUS_SPECIFIC for
164 (read_struct_type): Ditto. Also, add comments about how we can
165 deduce TYPE_VPTR_FIELDNO from inheritance info and fieldname info.
166 * coffread.c (decode_base_type): Allocate TYPE_CPLUS_SPECIFIC for
168 (read_struct_type): Ditto.
169 * dwarfread.c (struct_type): Ditto.

182 * mipsread.c (parse_partial_symbols): patch to keep DEC C
183 compiler from making gdb bomb out. Thanks to Ed Santiago!
185 Thu Nov 14 19:27:30 1991 Fred Fish (fnf at cygnus.com)
187 * symfile.c: Add function compact_misc_function_vector() to
188 remove duplicate misc function vector entries. See comments
189 in source for why this is necessary/desirable.
191 * dwarfread.c: Add misc function type parameter to internal
192 record_misc_function(). Remove calls to init_misc_bunches()
193 and condense_misc_bunches(), these are now done in elfread.c.
195 * elfread.c: Add support for reading bfd canonical symbol tables
196 and generating misc function vector entries for global and
197 absolute symbols. Do calls to init_misc_bunches() and
198 condense_misc_bunches() where they will enclose all calls to
199 record_misc_function(), including those in dwarfread.c.
201 Thu Nov 14 17:02:11 1991 Roland H. Pesch (pesch at cygnus.com)
203 * doc/Makefile.in: new targets gdb.me, gdb.ms, gdb.mm
204 (roffable documentation).
205 * doc/gdb.texinfo: embedded hints (as comments) for better
206 texi2roff conversion.
208 Thu Nov 14 13:18:25 1991 John Gilmore (gnu at cygnus.com)

222 Motorola 88000 port without tears, I mean without tdescs.
224 * m88k-tdep.c: Blow away all tdesc stuff.
225 Provide functions for all the frame-related macros in
226 tm-delta88.h. Adopt i960-style EXTRA_FRAME_INFO.
227 (examine_prologue, frame_find_saved_regs, skip_prologue): borrow
228 from i960-tdep.c and adapt to the function prologues on the 88k.
229 (read_next_frame_reg): Borrow from mips-tdep.c.
230 FIXME: frame_locals_address should go away.
232 * tm-delta88.h: Dump all the tdesc stuff.
233 Macros for all frame-related stuff call fns of same name.
234 Remove duplicated definitions. FP_REGNUM becomes same as
237 * xm-88k.h: Eliminate lots of library dependencies, now handled
238 in libiberty. Eliminate KDB nonsupport.
240 * doc/gdbint.texinfo: Add rudiments on frames. FIXME, add more.
243 * stack.c (frame_info): Mark frameless functions.
244 Print locals address (FIXME, remove if same).
245 * blockframe.c: Comment changes, FIXME after.
246 * coffread.c: Even without TDESC, need to zap "@" symbols.
247 Don't register for wierd format names; change the names in BFD.

261 Allow setting breakpoints on C++ destructors.
262 * valops.c (destructor_name_p): Don't check TYPE_HAS_DESTRUCTOR,
263 since it lies. Rely on callers to catch missing destructors.
264 * symtab.c (decode_line_1): For example (see above), here.
265 * buildsym.c, symtab.h: Remove TYPE_FLAGS_HAS{CON,DE}STRUCTOR
266 flags since they are no longer used.
268 Fixes to support C++ methods with functional parameters.
269 * c-exp.y (func_mod rule): Allow (and ignore) list of parameter
270 types in a function type.
271 * eval.c (parse_and_eval_type), value.h: New function,
272 parse_and_eval_type, is based on old code from check_stub_method.
273 But don't actually evaluate the cast, since that calls
274 value_cast(), whcih may fail. Just extract the type
275 from the parsed expression.
276 * values.c (check_stub_method): While looping through the
277 arguments, adjust depth *after* parameter has been handled.
278 Replace call and setup of parse_and_eval with new function
281 Tue Nov 12 09:40:07 1991 Fred Fish (fnf at cygnus.com)
283 * utils.c, rem-multi.shar: Remove fixed arg count version of
286 * altos-xdep.c, arm-xdep.c, coffread.c, command.c, convex-xdep.c,

288 m88k-xdep.c, main.c, printcmd.c, pyr-xdep.c, source.c,
289 sun386-xdep.c, symm-xdep.c, umax-xdep.c, values.c, xcoffread.c:
290 Change all instances of use of fixed args concat() to variable
291 args concat() now located in libiberty.
293 Tue Nov 12 07:23:46 1991 John Gilmore (gnu at cygnus.com)

299 * rs6000-pinsn.c, rs6000-tdep.c, rs6000-xdep.c, tm-rs6000.h,
300 xm-rs6000.h, rs6k-opcode.def, rs6k-opcode.h: New files.
301 * xcoffexec.c: New file for handling AIX shared libraries.
303 Mon Nov 11 19:14:31 1991 Fred Fish (fnf at cygnus.com)

306 (and possibly arguments to) the program that generated a core
309 * elfread.c: Remove the register_addr() stub now that it is no
312 * procfs.c: Move misplaced #endif for ATTACH_DETACH. Add new
313 fetch_core_registers() function for core file support.

317 * dwarfread.c (dwarf_psymtab_to_symtab): Remove leftover call
318 to do_cleanups() which resulted from a previous change.
320 * elfread.c: Re-enable compilation of register_addr() stub
321 whenever it is not supplied by coredep.c
323 Sat Nov 9 00:40:32 1991 John Gilmore (gnu at cygnus.com)
325 Add tracking of object files (that contain symbols) to gdb.
326 This includes a "struct objfile" that owns symtabs and psymtabs
327 that were read in from that binary file.
329 * symfile.h: Add struct objfile. Add pointer to the objfile
330 into the struct sym_fns.
331 Replace global `symfile' and `symfile_mtime' with
332 `symfile_objfile'. Add global object_files chain.
334 * symfile.c: Move param.h above symtab.h.
335 (sort_misc_function_vector): Add.
336 (syms_from_objfile): Was syms_from_bfd.
337 (symfile_open): Now returns objfile.
338 (allocate_objfile): New.
339 (free_objfile): New, replacing free_all_.*symtabs.

361 (dbx_alloc_type): Check file number, not sym number, for -1.
362 (find_symbol_in_list): Add for xcoffread.
363 (start_symtab): Default typevector is empty. Keep reusing same
365 (end_symtab): Take objfile argument and pass it to

391 (struct symtab): Add objfile * and objfile_chain * of symtabs.
392 (struct partial_symtab): Add objfile * and objfile_chain * of
393 psymtabs. Remove symfile_name.
395 * symmisc.c: Lose free_all_symtabs, free_all_psymtabs.

397 listing if 2nd argument given. Print objfile info.
398 (printpsyms_command): Rename from print_partial_symtabs. Ditto all.

402 * symfile.h, symfile.c, symtab.h: Lint
404 Fri Nov 8 23:38:48 1991 John Gilmore (gnu at cygnus.com)
406 * command.c: Include param.h.
407 * defs.h (warning_setup, warning): Declare.

413 Thu Nov 7 18:26:15 1991 Steve Chamberlain (sac at rtl.cygnus.com)
415 * Makefile.in: link with libiberty after libreadline, since
416 readline might want something in libiberty.
417 * m88k-xdep.c: Fixed the register offsets in the ptrace_user
418 struct for BCS 88k machines.
419 * xm-m88k.h: don't define USIZE if already defined.
420 * configure.in: Added delta88 target.
422 Thu Nov 7 04:51:19 1991 John Gilmore (gnu at cygnus.com)
424 * am29k-pinsn.c, am29k-opcode.h: Fix decoding of mtacc, dmac, fmac.
426 * tm-*.h: Remove READ_DBX_FORMAT, COFF_FORMAT, and
427 READ_MIPS_FORMAT, which have been unused since BFD. Still
428 remaining is COFF_NO_LONG_FILE_NAMES.
429 * tm-sun3.h, tm-altos.h: Remove detritus accidentally left from
430 function calling code moved to m68k-tdep.c.
432 Wed Nov 6 17:21:59 1991 John Gilmore (gnu at cygnus.com)
434 * coffread.c: Eliminate c_nsyms in favor of c_naux.
435 Complain if no auxents on .bf and .ef FCN symbols, and assume
436 lots of line numbers.
437 (init_linenos, enter_linenos): Use a sentinel at the end of the
438 read-in linenos, to make for a fast, safe loop-end test.
440 Wed Nov 6 02:54:08 1991 Steve Chamberlain (sac at cygnus.com)
442 * coffread.c (read_coff_symtab): coffread used to rely on the
443 x_sym.x_misc.x_lnsz.x_lnno field giving the # of linnos in a
444 function. Two of the formats I'm using (29k and 88k) don't seem to
445 set it. Ths patch to fcn_last_line and (enter_linenos) is an
446 attempt to use the actual size of the linno table in the file to set
447 the number of linenos to process.
449 Tue Nov 5 22:47:46 1991 Steve Chamberlain (sac at cygnus.com)
451 * Makefile.in: put a - infront of the mv y.tab.c c-exp.tab.c and
452 mv y.tab.c m2-exp.tab.c, so that if bison is used, and the files
453 are created in place, so the mv fails, then the make continues.
455 Tue Nov 5 16:47:47 1991 Per Bothner (bothner at cygnus.com)
457 Add C++ as a separate language.
458 * defs.h (enum language): Add language_cplus.
459 * dwarfread.c (end_symtab): Support language_cplus.
460 * c-exp.y: Add new struct language_defn cplus_language_defn.
461 Don't set c to be the default language (see main.c).
462 * c-exp.y (yylex): Only look for field of this if
463 language is C++. (First difference from C!)
464 * language.c: Add case branches for C++ (currently, all
465 the same as C). Also, add c++ to "usage" note for "set lang".
466 * valprint.c (typedef_print). Add case branches for C++.
467 * main.c (main): New way to set initial language: Look at
468 file extension of psymtab containing main(). (Same as we
469 do for symtabs, but avoid loading the symtab yet.)
470 * symtab.c: New routine find_main_psymtab(), used by main()
471 to set initial language.
472 * symfile.c (allocate_symtab): Move code for mapping file
473 extensions-> languages to new deduce_language_from_filename().
475 Fix a C++ problem when looking for methods in super-classes.
476 There was confusion between base and derived types.
477 * valops.c (value_fn_field): Change function interface.
478 * values.c: Use new value_fn_field interface.
480 Mon Nov 4 10:49:33 1991 Per Bothner (bothner at cygnus.com)
482 * infrun.c: Fixed typo in comment.
483 * utils.c: All the v*fprintf emulation is now in libiberty,
484 so we can get rid of some junk.
485 * xm-sun3os4.h, xm-sun4os4.h, xconfig/decstation, xconfig/i386sco,
486 xconfig/sun3os4, xconfig/sun4os4: Don`t need HAVE_STRSTR any more.
487 * m68k-pinsn.c (print_insn_arg): Support BB/BW/BL
488 type operands, as used by branch instructions.
489 * gmalloc.c: Fix prototype of memcpy.
490 * elfread.c: Comment out register_addr, since it conflicts
491 with the one in coredep.c.
492 * buildsym.h: Remove extern declarations of two functions
493 that are really static in buildsym.c.
494 * tm-mips.h: Add symbolic names for more registers.
495 * mips-xdep.c (store_inferior_registers): Use new register names.
496 * xm-mips.h: Simplify REGISTER_U_ADDR, since it is now
497 only used for core files, not ptrace. Therefore,
498 the KERNEL_U_ADDR hack is no longer needed.
499 The mapping to ptrace number is now in in mips-xdep.c.
500 * mips-xdep.c: Define REGISTER_PTRACE_ADDR (using the
501 mapping from the old REGISTER_U_ADDR), and use it
502 in {fetch,store}_inferior_registers.
503 * mipsread.c: Rename #include ecoff.h to new name coff-mips.h.
504 * mips-tdep.c (mips_push_dummy_frame, mips_pop_frame):
505 Save/restore FP regs correctly (?).
506 * dbxread.c: Remove duplicate define_symbol and type_synonym_name
507 (these had been previously moved to buildsym.c).
508 Hence, define_symbol becomes extern instead of static.
509 * buildsym.c (read_struct_type): Comment out bogus handling
510 of C++ operator methods. Minor hacking of reading of class
511 contexts. Make define_symbol non-static, so dbxread.c can call it.
513 Fri Nov 1 11:05:47 1991 John Gilmore (gnu at cygnus.com)
515 * mipsread.c (read_mips_symtab, read_the_mips_symtab): Use real
516 filename with error messages.
517 * stack.c (frame_select_command): Rename to select_frame_command
518 to avoid "fr" and "fra" having nonunique completions.
519 * symfile.c (sort_symtab_syms): Ignore sort of zero symtab *.
520 (symfile_init): Print file format name when unable to handle it.
521 (free_named_symtabs): Use BLOCKVECTOR rather than obsolete BLOCKLIST.
522 * symmisc.c (free_symtab): Only free linetable if nonzero.
523 * symtab.h: Remove obsolete BLOCKLIST macros.
525 Thu Oct 31 18:12:43 1991 Stu Grossman (grossman at cygnus.com)
527 * infrun.c (wait_for_inferior): another stepi/nexti fix. Ensure
528 that stop_step is 1 at bottom of main loop. I don't know why this
529 needs to be done, but it helps me sleep better at night.
531 Sun Oct 27 18:18:39 1991 Stu Grossman (grossman at cygnus.com)
533 * main.c (initialize_history): Read history after reading all
536 Sun Oct 27 14:09:25 1991 John Gilmore (gnu at cygnus.com)
538 * buildsym.c: Break out initial malloc sizes.
539 (record_line): Record directly in a subfile. Alloc on demand.
540 (compare_line_numbers): Add from xcoffread.c.
541 (end_symtab): New params say whether to sort pendings and
542 linetable. Patch block stabs if defined. Shrink linetable before
543 allocating the symtab.
544 * buildsym.h: Delete line_vector* and prev_line_number. Add
545 global_stabs and file_stabs for xcoffread.
546 * dbxread.c (start_subfile): Move to buildsym. Change above calls.
547 * symtab.h: LINETABLE(symtab) can now be null. Zap LINELIST.
548 * symmisc.c, symtab.c: Cope with null LINETABLEs.
550 * blockframe.c: Pass fromleaf to INIT_EXTRA_FRAME_INFO.
551 * tm-29k.h, tm-88k.h, tm-i960.h, tm-irix3.h, tm-mips.h, tm-pyr.h,
552 tm-sparc.h: Accept fromleaf parameter.
553 * c-exp.y (yyerror): Pass error message if given.
554 * configure.in: Add rs6000 host and target.
555 * inflow.c (new_tty): O_NOCTTY kludge for RS/6000.
556 * symfile.h (entry_point): Add.
558 Sat Oct 26 00:16:32 1991 John Gilmore (gnu at cygus.com)
560 * buildsym.c: New file. Breaks out symbol-table-building routines
561 from dbxread.c, so they can be shared with xcoffread.c.
562 * buildsym.h: New file. Declarations for buildsym.c users.
563 * dbxread.c: Remove large chunks into buildsym.c.
564 * Makefile.in: Add buildsym.c and buildsym.h.
566 * symfile.c (syms_from_bfd): New routine.
567 (add_symbol_file): Call it to do the real work.
568 (syms_from_bfd): Initialize entry_point before calling symfile_init.
569 * symtab.h, symfile.c, coffread.c, mipsread.c, dwarfread.c:
570 Avoid declaring or setting entry_point (symfile.h & symfile.c cope).
572 Fri Oct 25 10:58:16 1991 Mark Eichin (eichin at cygnus.com)
574 * cplus-dem.c (cplus-demangle): added support for templates, static
575 data, and the new (correct) mangling for destructors.
577 * dwarfread.c: (dwarfwarn): created a varargs version of
578 dwarfwarn, for non __STDC__ compilers.
580 * c-exp.y: (yylex): added match for "template" token.
581 (typebase): added TEMPLATE name '<' type '>' clause, for explicit
582 specification of template types.
584 * symtab.c: (lookup_template_type): new function for finding
585 templates in symbol table.
586 (type_name_no_tag): changed to explicitly check for s/u/e at the
587 beginning of the symbol - if it is a template, none of these will
588 be there (but the name will still contain spaces.)
590 Fri Oct 25 18:59:32 1991 Per Bothner (bothner at cygnus.com)
592 Various fixes to improve g++ debugging.
593 * symtab.h: Add is_const and is_volatile flags for each method.
594 These are bit fields - take their space from voffset,
595 which shrinks to 30 bits. Since voffset is now a bitfield,
596 make it unsigned for portability. This changes its interpretation
597 slightly: Static methods now have voffset 1 instead of -1,
598 and virtual offsets start at 2, not 1.
599 * symtab.c: Renamed gdb_mangle_typename to gdb_mangle_name,
600 since it now returns an entire magled method name, not just
601 the type part. This avoids some duplication.
602 It also allows us to correctly mangle const and volatile
603 methods (using the new is_const and is_volatile bit fields
605 * valprint.c (type_print_base), values.c (check_stub_method):
606 Simplify by using new gdb_mangle_name.
607 * values.c (value_headof): Fix to correctly handle single
608 inheritance (actually two fixes, either of which suffices).
609 * dbxread.c (read_struct_type): Handle const and volatile
611 * dbxread.c (read_struct_type): Yet one more place where
612 we must handle '\\' continuations.
613 * valprint.c (vtbl_ptr_name): Add final '\0'.
615 Fri Oct 25 16:06:38 1991 Stu Grossman (grossman at cygnus.com)
617 * tm-sparc.h, tm-68k.h (EXTRACT_RETURN_VALUE): fix output of
618 short return values for sparc and 68k. Patch from Paul Eggert.
620 * coffread.c, coredep.c, i386-xdep.c: install patches for
621 SysV/386 3.2 from Mauro DePalma.
623 Fri Oct 25 02:02:13 1991 John Gilmore (gnu at cygnus.com)
625 * core.c (core_file_info), exec.c (exec_file_info): Print file
626 type. Use printf_filtered.
628 * valops.c (value_fetch_lazy): Avoid 0-length fetches.
630 Thu Oct 24 23:06:40 1991 Fred Fish (fnf at cygnus.com)
632 * dwarfread.c: Add casts to remove compiler warnings.
634 * tm-3b1.h, tm-68k.h, tm-altos.h, tm-amix.h, tm-hp300bsd.h,
635 tm-hp300hpux.h, tm-isi.h, tm-news.h, tm-pn.h, tm-sun2.h,
636 tm-sun3.h: Remove locally duplicated code for calling functions
637 in the inferior. The only differences were in the specific trap
638 vectors used and whether or not an fpu was present. These are
639 now handled by appropriate definitions of BPT_VECTOR and
640 HAVE_68881 respectively. Other minor obvious cleanups.
642 * valops.c: Correct a minor misspelling.
644 * utils.c: Remove local BSD/USG hacks that are now in libiberty.
646 * dwarfread.c: Remove prototype for dwarfwarn. Does not work
649 Thu Oct 24 09:33:44 1991 John Gilmore (gnu at cygnus.com)
651 * stack.c (frame_command): Always print. Use new
652 frame_select_command to select a frame without printing.
654 * dwarfread.c: Use <varargs.h>, since <stdarg.h> is not portable.
656 Thu Oct 24 01:32:51 1991 Fred Fish (fnf at cygnus.com)
658 * dwarfread.c: New file for DWARF debugging format support.
660 * elfread.c: New file for ELF object file format support.
662 * procfs.c: New file for SVR4 /proc (process file system) support.
664 * tm-amix.h, xm-amix.h, tconfig/amix, xconfig/amix: New files for
667 * xm-svr4.h, tm-svr4.h: New files for SVR4 support.
669 * xm-m68k.h: New file for host machines with m68k cpu.
671 * Makefile.in: Add elfread.c and dwarfread.c to SFILES_MAINDIR.
672 Add elfread.o and dwarfread.o to OBS.
674 * symfile.h: Add "elf" to list of supported formats in comment.
676 * c-exp.y, defs.h, symtab.h, valprint.c: Add three new builtin
677 types to gdb, builtin_type_long_double, builtin_type_complex, and
678 builtin_type_double_complex. Add and use new TARGET_SHORT_BIT,
679 TARGET_INT_BIT, TARGET_LONG_BIT, TARGET_FLOAT_BIT,
680 TARGET_DOUBLE_BIT, TARGET_LONG_DOUBLE_BIT, TARGET_COMPLEX_BIT, and
681 TARGET_DOUBLE_COMPLEX_BIT, as the sizes in bits of the indicated
682 types on the target machine (ala the existing TARGET_LONG_LONG_BIT).
684 * infrun.c: When using SVR4 /proc interface instead of ptrace(),
685 call proc_set_exec_trap() to setup child to stop at first instruction.
687 * inftarg.c: When using SVR4 /proc interface, call proc_wait()
690 * m68k-tdep.c: Add new routines supply_gregset(), fill_gregset(),
691 supply_fpregset(), and fill_fpregset(), which are machine
692 dependent support routines for SVR4 /proc interface.
694 * utils.c: Add warning_setup() and warning(). Warning() behaves
695 the same as error() except that it returns normally rather than
696 jumping back to command level. Modules that don't want to call
697 warning() for some reason, but want to produce their own warnings,
698 can call warning_setup() to ensure compatibility with the way
699 warning() and error() deal with the terminal.
701 * symtab.c: Make internal errors produce more useful messages.
703 * tm-68k.h: Move code that is duplicated in almost every single
704 m68k based machine's configuration files to this common file.
705 Duplications in the configuration files still need to be removed
708 * infrun.c (child_create_inferior): System V versions must call
709 setpgrp() with no arguments, to comply with prototyping typically
712 * munch: Add support for SVR4 style nm output.
714 * dbxread.c, mipsread.c symmisc.c, symtab.c: Remove the object
715 file specific fields from the partial symbol table structure and
716 replace them with a pointer to private data for each different
717 flavor of object file reader to initialize appropriately.
719 Wed Oct 23 09:38:20 1991 John Gilmore (gnu at cygnus.com)
721 * xconfig/sun[34]os4: Add note about strstr botch on sunos4.0.3c
724 * mipsread.c (fixup_undef_type): New function. If a struct /
725 union / enum is defined in a header file but nowhere else used,
726 (by typedefing, pointer referencing or declaration) the mipsread code
727 builds the complete tree for the structure but leaves its code as
728 TYPE_CODE_UNDEF as it doesn't know what kind of aggregate it is.
729 Guess its type based on the details of the members.
731 Tue Oct 22 18:04:32 1991 Stu Grossman (grossman at cygnus.com)
733 * infrun.c (wait_for_inferior): Check return value from
736 Mon Oct 21 17:47:03 1991 Stu Grossman (grossman at cygnus.com)
738 * infrun.c (wait_for_inferior): fix stepi/nexti that was broken
739 by my last edit to this routine.
741 Mon Oct 21 14:27:43 1991 John Gilmore (gnu at cygnus.com)
743 * tm-sun3.h (FIX_CALL_DUMMY): problem with cross debugging.
744 FIX_CALL_DUMMY does unaligned accesses and/or forgets to byte swap
745 the values before putting them into the dummy code. (From Peter
748 Mon Oct 21 10:04:39 1991 Steve Chamberlain (steve at rtl.cygnus.com)
750 * configure.in: added ebmon target.
752 Wed Oct 16 22:49:58 1991 John Gilmore (gnu at cygnus.com)
756 * Makefile.in: Roll VERSION to 4.2.
757 * README, TODO, WHATS.NEW: Update.
759 * core.c (core_open): Improve error message for bad file.
760 Pass .reg virtual memory address to fetch_core_registers to help
761 it find the registers in the core-file header.
762 * coredep.c (fetch_core_registers): Take new argument, use it,
763 and pass it to register_addr to locate the block of registers.
764 * xm-mips.h: Update KERNEL_U_ADDR for new scheme. Cleanup a bit.
766 * dbxread.c (read_dbx_symtab, process_one_symbol): Handle
767 Sequent N_FN_SEQ like everybody else's N_FN.
769 * main.c: Circumvent SCO cc bug with #if !!defined(USG).
770 * tm-i386v.h: #endif guck.
771 * xconfig/i386*: Remove -Dgetpagesize()=4096 kludge.
772 * xconfig/i386sco: Add HAVE_STRSTR to avoid ANSI bdeath.
773 * xconfig/tahoe: Add REGEX, which seems to be missing.
775 * coredep.c: Add <sys/types.h> for SCOnix.
776 * dbxread.c (read_dbx_symntab): Avoid coredump on malformed file.
777 * printcmd.c (print_formatted): Flush output before disassembly.
779 Tue Oct 15 20:12:32 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
781 * doc/refcard.tex (sec "Working Files"): consistent metavars and
782 other improvements, due to comments by François Pinard
783 (pinard@iro.umontreal.ca)
785 * doc/gdb.texinfo (appendix "Installing GDB"): changes in
786 configure, and improvenets related to Pinard's refcard comments
788 Tue Oct 15 08:45:12 1991 John Gilmore (gnu at cygnus.com)
790 Changes from Fred Fish:
791 * tm-68k.h (FPI_REGNUM): Add.
792 * infrun.c (child_create_inferior): flush stdout and stderr
794 * configure.in: Handle amigados, amix hosts and targets.
795 * inflow.c: Handle TIOCGLTC_BROKEN for Amiga.
798 * values.c (show_convenience): Use printf_filtered.
799 * main.c (define_command): Check result of lookup_command for
801 (echo_command): Use printf_filtered, and force output out.
803 * dbxread.c (read_enum_type): Avoid Modula-2 kludge that breaks C
805 * i387-tdep.c (double_to_i387): Fix typo for double_to_ieee_extended.
806 * utils.c (_initialize_utils): If !ISATTY, don't paginate.
807 * configure.in, tconfig/decstation, xconfig/decstation: Rename
808 dec3100 to decstation.
810 Mon Oct 14 13:37:50 1991 Roland H. Pesch (pesch at cygnus.com)
812 * doc/gdb.texinfo: Catch up to changes recorded here in ChangeLog
813 (nodes Continuing and Stepping; Memory; Targets) clarifications
816 Fri Oct 11 23:27:06 1991 John Gilmore (gnu at cygnus.com)
818 * tm-{irix3,mips,nindy960,pn,symmetry,vx960}.h: Move
819 REGISTER_U_ADDR to corresponding xm- file. Sugg. by Peter Schauer.
821 * symmisc.c (print_partial_symtabs): Add printpsyms debug cmd.
823 * m68k-tdep.c (m68k_push_dummy_frame, m68k_pop_frame): Add
824 generic routines for calling inferior functions.
826 * blockframe.c (inside_main_scope, inside_entry_scope): New.
828 * copying.awk: Filter formfeeds out of copying & warrantee.
829 Make them available as `show copying' and `show warrantee' also.
830 * main.c (print_gnu_advertisement): Advt `show' commands.
832 Thu Oct 10 17:25:47 1991 John Gilmore (gnu at cygnus.com)
834 * mach386-xdep.c: Even when cross-compiling, leave in the
835 core-file reading code.
836 * core.c (get_core_registers): Avoid coredump if no .reg section.
838 Wed Oct 9 17:03:34 1991 John Gilmore (gnu at cygnus.com)
840 * mipsread.c, coffread.c: initialise TYPE_VPTR_FIELDNO to -1.
841 This avoids coredumps under `set print object on' in value_headof
842 (called erroneously by value_from_vtable_info) for `p &struct'
843 or `p *struct'. From Peter Schauer.
845 Mon Oct 7 00:06:52 1991 John Gilmore (gnu at cygnus.com)
847 * Makefile.in: Roll version to 4.1.2.
848 * dbxread.c: Use aout64.h, not a.out.gnu.h. Get external symbol entry
849 size from BFD (but, FIXME, we don't yet read external nlists's and
850 convert them to internal nlists's before handling them -- we still
851 assume they have the same size and alignment.) Use SET_NAMESTRING
853 * exec.c (exec_file_command): Move dead coff-encapsulation code
855 * m88k-tdep.c, m88k-xdep.c: Remove encap test and #inc <a.out.h>.
857 Fri Oct 4 22:30:06 1991 John Gilmore (gnu at cygnus.com)
859 * configure.in, tm-i386v.h, xm-i386v.h: Intel 386 Mach host port.
860 * xm-i386mach.h, mach386-xdep.c, xconfig/i386mach: New files.
862 Fri Oct 4 17:04:31 1991 Per Bothner (bothner at cygnus.com)
864 More patches from Peter Schauer <pes@regent.e-technik.tu-muenchen.de>:
865 * mips-xdep.c (store_inferior_registers): Don't try to
866 write the (pseudo) FP.
867 * mipsread.c (parse_partial_symbols): Improved algorithm for
868 setting pst->texthigh.
870 Fri Oct 4 16:47:32 1991 Roland H. Pesch (pesch at cygnus.com)
872 * doc/Makefile: make TEXINPUTS include . everywhere
874 Fri Oct 4 00:35:56 1991 John Gilmore (gnu at cygnus.com)
876 * coffread.c, dbxread.c, symfile.c, symmisc.c, symtab.h: Remove
877 vestiges of typevectors, which were for symsegs and are no longer
878 used. (From a question by Eliot Dresselhaus
879 <dresselh@RFT30.nas.nasa.gov>).
881 Thu Oct 3 09:33:26 1991 John Gilmore (gnu at cygnus.com)
883 * dbxread.c, coffread.c: static-ize functions that were
884 gratuitiously external. (From Fred Fish.)
886 * c-exp.y: sym->class to SYMBOL_CLASS (sym).
888 * dbxread.c (dbx_lookup_type): Keep doubling size of typevector
889 until it is large enough.
891 * dbxread.c (read_type): Handle error case slightly better.
892 Make complaint message not C++-specific.
894 Wed Oct 2 17:21:07 1991 Stu Grossman (grossman at cygnus.com)
896 * infrun.c (wait_for_inferior): Fix step/next so that you only
897 stop at the beginning of a new line. This fixes various problems
898 with for loops, nested if-else's and switch statements.
900 Tue Oct 1 06:33:55 1991 John Gilmore (gnu at cygnus.com)
902 * symtab.c (lookup_symtab_1, lookup_symbol): "fatal" errors
903 between symtabs and psymtabs become ordinary error()s.
905 * dbxread.c (read_dbx_symtab): Relocate end_of_text_addr
906 properly, making "end pc" correct in shared lib psymtabs.
907 (From Guy Harris <guy@auspex.com>.)
909 Mon Sep 30 13:15:31 1991 John Gilmore (gnu at cygnus.com)
911 * dbxread.c: Enable, but soften, const_vol_complaint.
912 (read_dbx_symtab): N_STSYM and N_LCSYM define static vars.
913 Ditto Gould N_NBSTS and N_NBLCS. Also, all types in the psymtab
914 should be file-scope, not global.
915 (read_struct_type): Remove ancient multiple-inheritance warning.
916 (read_range_type): Check base type, complain & patch if undefined.
917 * stack.c (frame_info): Demangle the function name in `info stack'.
920 Sat Sep 28 10:02:33 1991 John Gilmore (gnu at cygnus.com)
922 * eval.c (evaluate_subexp_for_address): Don't use
923 TYPE_POINTER_TYPE directly (it might be zero if this type has
924 never had a pointer created before); use lookup_pointer_type.
925 * symtab.c (lookup_method_type): Arguments were swapped in all
926 callers, so fix it here. I'm amazed this worked at all!
928 Fri Sep 27 18:09:31 1991 John Gilmore (gnu at cygnus.com)
930 * c-exp.y, m2-exp.y: Define more yysymbols that happen to be
931 "bss" rather than "data" symbols, but which still conflict.
934 * coffread.c (coff_symfile_read): Use xmalloc, not malloc.
935 * core.c (core_files_info): Shorten output.
936 * exec.c (exec_files_info): Ditto.
937 (build_section_table): Ignore zero-length sections.
938 * language.c, printcmd.c: Lint.
939 * language.h (get_frame_language): Declare.
940 * saber.suppress: update.
941 * stack.c (find_relative_frame): Remove complex code that was
942 #if 0'd, stick with simple code. Lint.
943 * saber.suppress: Update a bit.
944 * symfile.c (add_symbol_file_command): Add "?" to question.
945 * utils.c (parse_escape): Avoid \a due to bdead compilers.
946 * value.h: Declare typedef_print.
948 * valprint.c (val_print, type_print_base): TYPE_CODE_RANGE less
951 * nindy-tdep.c (nindy_frame_chain_valid): Use lookup_misc_func.
952 (Reported by Mark Peek <mark@imagen.com>.)
954 * solib.c (solib_map_sections): Relocate all sections, even
955 though only the text section's size is tracked. Mark ld_text
956 for eventual elimination as we generalize to N sections.
958 * infrun.c (wait_for_inferior): Don't check if the PC is in a
959 call_dummy if we were stopped by a random signal that is being
960 passed to the program. This produced wierd results when calling
961 functions in the inferior and signals (e.g. SIGALRM) were in use.
963 Tue Sep 24 18:05:30 1991 John Gilmore (gnu at cygnus.com)
965 * infrun.c (IN_SIGTRAMP): Not parenthesized properly.
966 Bugfix from Paul Eggert <eggert@twinsun.com>.
967 * tm-ultra3.h (IN_SIGTRAMP): Ditto.
968 * valprint.c (print_floating): Print 9 digits for IEEE floats.

977 Fri Sep 20 16:10:52 1991 John Gilmore (gnu at cygnus.com)
981 * Makefile.in (VERSION): Set to 4.1.
982 * language.c (set_language_command): Print useful help message,
983 and restore the language string after giving help.
984 * valprint.c (typedef_print): Print typedef in C or M2.
985 * symtab.c (list_symbols): Use it.
986 * main.c (main): Avoid any output before (gdb) prompt when -q.
987 * language.c (set_language_command): Handle errors by restoring
988 the language string to its current state (fix from A. Beers).
989 * doc/gdbint.texinfo: Roll in information from README. Rearrange
990 "how to install" and "how to print the doc" stuff so it drops
992 * configure.in: Rename rtpc CPU to romp to match config.sub.
993 * README, WHATS.NEW, TODO: Update for gdb-4.1.
995 Fri Sep 20 17:39:14 1991 Roland H. Pesch (pesch at cygnus.com)
997 * doc/gdb.texinfo: Updates from ChangeLog. set/show write,
998 autoloading shared libs, copyright etc on GDB startup, clean up $_
999 and $__ index refs, set/show listsize and related updates to list
1000 cmd. New host/target configs.
1002 Fri Sep 20 15:46:00 1991 Roland H. Pesch (pesch at cygnus.com)
1004 * doc/Makefile: generate aux version-no file doc/gdbVN.m4
1005 from main Makefile.in version definition
1006 doc/gdb.texinfo: use version recorded in doc/gdbVN.m4 for current
1008 Makefile.in (setup-to-dist): generate doc/gdbVN.m4
1010 * doc/gdb.texinfo: merge new language-switching and lang-specific
1013 Fri Sep 20 15:00:57 1991 Per Bothner (bothner at cygnus.com)
1015 * mcheck.c: Add __ONEFILE kludge to allow compilation by non-ANSI
1016 compilers (which may lack stddef.h).
1018 Fri Sep 20 13:29:42 1991 John Gilmore (gnu at cygnus.com)
1020 * dbxread.c (read_dbx_symtab, process_one_symbol): N_FN and
1021 N_WARNING are the same except for the N_EXT bit, so just use their
1022 values alone, rather than OR-ing them with N_EXT.
1024 Fri Sep 20 12:27:55 1991 Stu Grossman (grossman at cygnus.com)
1026 * mipsread.c (parse_lines): Deal with negative extended line
1029 * c-exp.y, m2-exp.y: #define yyerrflag and yynerrs to avoid
1030 global symbol conflicts.
1032 Fri Sep 20 02:28:15 1991 John Gilmore (gnu at cygnus.com)
1034 * .gdbinit: Move 'set complaints' to top, so it runs even in
1035 case we aren't debugging GDB.
1036 * language.c (_initialize_language): Fix type check and range
1037 check documentation strings.
1038 * utils.c (!HAVE_VPRINTF): Define vfprintf as a function, so
1039 language.c can use it. (Though language.c should really not be
1040 handling warnings/errors the way it does, FIXME.)
1041 * symtab.c (lookup_primitive_type): const lint.
1043 Bugfix from Peter Schauer:
1044 * source.c (lines_to_list): Make signed, to avoid comparison
1045 going unsigned and complaining that -3 is too high for 21 lines.
1046 * stack.c (lines_to_list): Ditto.
1048 Thu Sep 19 23:33:41 1991 John Gilmore (gnu at cygnus.com)
1050 * Makefile.in (HFILES): Add minimon.h.
1051 (VERSION): Roll version number to 4.0.95.
1052 (gdb.tar.Z, make-proto-gdb.dir, setup-to-dist, gdb-XXX.tar.Z):
1053 New rules for building distributions. Normal distribution
1054 is built by doing `make -f Makefile.in gdb.tar.Z' in the directory
1055 one level up from here; it calls make-proto-gdb.dir to build a
1056 directory `proto-gdb' which is an image of the release. The old
1057 `gdb.tar.Z' rule still works too.
1058 * config.sub, configure: Roll in latest from ..
1060 Thu Sep 19 17:41:24 1991 Roland H. Pesch (pesch at cygnus.com)
1062 * doc/gdbint.texinfo: Reorder contents; reorganize new-host,
1063 new-target, and new-config chapters; fix minor typos; come closer
1064 to usual GNU markup conventions for @file @samp @code @var.
1066 Thu Sep 19 17:04:12 1991 Per Bothner (bothner at cygnus.com)
1068 Patches from Peter Schauer <pes@regent.e-technik.tu-muenchen.de>:
1069 * mipsread.c (parse_partial_symbols): Enter the name of all
1070 structs/unions... into the psymtab so we can access them if the
1071 symtab is not read in.
1072 * mips-tdep.c: Remove some unneeded #includes.
1073 * xconfig/dec3100: Add HAVE_STRSTR.
1075 Thu Sep 19 15:14:23 1991 John Gilmore (gnu at cygnus.com)
1077 * Makefile.in: Circumvent Sun Make bug on *-exp.tab.o.
1078 * c-exp.y, m2-exp.y: Lint.
1079 * m2-exp.y: Avoid using yytname[] which is a Bison-ism.
1080 * valprint.c (val_print_fields): Check for stub type.
1081 * mipsread.c (_initialize_mipsread): Avoid using
1082 builtin_type_void at initialize time.
1083 (mipscoff_symfile_read): use it now.
1085 Wed Sep 18 15:55:51 1991 John Gilmore (gnu at cygnus.com)
1087 Merge multiple-language support, and partial Modula-2 support,
1088 from Andrew Beers <beers@cs.buffalo.edu>.
1090 * i387-tdep.c: New file, consolidates most 80387 support,
1091 and eliminates host dependency on double<->extended conversions.
1092 * i386-xdep.c, symm-xdep.c: Remove most 387 support.

1099 * mipsread.c (new_symtab): Use it. Minor formatting changes.
1100 * dbxread.c (end_symtab): Use it.

1109 * coffread.c (end_symtab): Use allocate_symtab.
1110 (process_coff_symbol): #if 0'd for functions and params as above.
1111 (read_enum_type): Recognize Modula-2 BOOLEAN.
1112 * symtab.c (add_param_to_type): #if 0'd function to add a

1119 hex with local_hex_string for Modula-2 support.
1121 * breakpoint.c (breakpoint_cond_eval): Use new value_true to test

1148 TYPE_CODE_BOOL and TYPE_CODE_CHAR.
1150 * expression.h (enum exp_opcode): Add Modula-2 specific opcodes.
1151 * expprint.c: Look up expression opcodes in language-specific

1164 * language.h, language.c: New files for language-specific macros,
1165 declarations, and definitions.
1169 * main.c (main): If error() is called during early
1170 initialization, print its message and then exit(1) from GDB.

1184 Tue Sep 17 08:37:41 1991 John Gilmore (gnu at cygint.cygnus.com)
1186 Add Andrew Beers' changes for Modula-2 support. His ChangeLog
1187 entries are enclosed herein. Not all of these changes
1188 have been merged into the master GDB sources -- check the
1189 ChangeLog above here for the merge log.
1191 Mon Jun 3 17:05:45 EDT 1991
1193 m2-exp.y Created. Tested outside of GDB for a few days. Proper
1194 operators were added, C specific operators and tokens
1195 removed. yylex() revamped to some extent. Still things
1196 missing from the grammar, such as sets.
1197 Tested for two weeks in GDB v3.5.
1199 Tue Jun 11 17:23:48 EDT 1991
1201 m2-exp.y Added boolean constants TRUE and FALSE to the grammar
1202 so they are built-in. Sort of a hack.
1204 Fri Jun 14 12:53:51 EDT 1991
1206 m2-exp.y Added range checking for numeric constants. Any numeric
1207 constant is assumed to be of builtin type INTEGER unless:
1208 (1) it is octal or hexadecimal, in which case it is a
1209 CARDINAL; (2) it is too big to fit into an INTEGER, in
1210 which case it is a CARDINAL.
1211 eval.c Added simple range checking for +, -, and * on integers.
1212 Doesn't work very well for *, since 6 * 1,000,000,000 =
1213 1,705,032,704, which fails the simple test of result >=
1214 first_operand, no matter in what order the operands are.
1216 Tue Jun 18 14:11:30 EDT 1991
1218 Broke the parser into parts, one containing the C grammar and the other
1219 containing code to be shared by all of the grammars.
1221 The following files no longer exist:
1226 The following files were added:
1228 c-exp.y (The C grammar)
1229 m2-exp.y (The Modula-2 grammar)
1230 parser-code.c (Code that is shared by the above grammar)
1234 Makefile.dist Changed to reflect the above dependencies. NOTE: It is
1235 now necessary to use the Bison compiler compiler, since it
1236 will generate function/variable prefixes other than yy.
1238 Tue Jun 18 16:47:49 EDT 1991
1240 symtab.[ch] Added the external variable working_lang, than holds the
1241 value of the current working language.
1242 Added the ennumerated type language_mode, with the values
1243 language_auto and language_manual, the former meaning that
1244 GDB sets working_lang as needed, and the latter meaning
1245 that the value of working_lang is totally under user
1247 symtab.[ch] Added the Modula-2 pervasive types INTEGER, CARDINAL,
1248 REAL, BOOLEAN and CHAR. Also added the type codes
1249 TYPE_CODE_BOOL and TYPE_CODE_CHAR.
1250 utils.c Added set_language_command and show_language_command to
1251 implement the GDB support commands "set language" and
1253 expression.h A number of identifiers were added to the type exp_opcode
1254 to facilitate Modula-2 builtin functions, integer
1255 division, and array indexing.
1257 Wed Jun 19 13:25:58 EDT 1991
1259 language.h Added the macro STRICT_TYPE, which evaluates to non-zero
1260 if the language specified by working_lang requires the use
1261 of strict typing of expressions. Eventually, even this
1262 will be able to be changed by the user.
1263 Added the macro RANGE_CHECK, which evaluates to non-zero
1264 if the language specified by working_lang requires the
1265 checking of a value against the domain of its type.
1266 Eventually, even this will be able to be changed by the
1268 language.[ch] Predicates involving types (simple_type, ordered_type,
1269 same_type, integral_type, numeric_type, character_type,
1270 boolean_type, float_type) are added. These predicates are
1271 based on the current value of working_lang, and are handy
1274 Wed Jun 19 15:39:34 EDT 1991
1276 eval.c Added the function type_array_rank which computes the rank
1278 valarith.c Added the funtion value_bool, which when given a integer
1279 value.h value (ie. struct value *) as an argument, it returns a
1280 boolean value (ie. struct value *) true if that integer
1281 is non-zero, and a boolean value false otherwise.
1282 valprint.c Added cases for TYPE_CODE_BOOL, so Modula-2 BOOLEAN values
1283 will print out properly.
1285 Wed Jun 19 16:36:34 EDT 1991
1287 valops.c Added the function value_capitalize, which returns it
1288 value.h argument capitalized if its argument is a lowercase
1289 letter, or the argument unchanged if its argument is not a
1291 valarith.c Added the function range_check_p, which returns non-zero
1292 value.h if its value argument is between the integral bounds upper
1294 Added the function range_check_enum_p, which makes sure
1295 that its value argument is a valid member of the domain of
1297 Added the function range_check_range_p, which makes sure
1298 its value argument lies between the upper and lower bounds
1299 of its type argument, which must be a ranged type.
1300 Added the function check_array_index, which range and type
1301 checks an index of an array.
1302 Added the function value_multi_subscript, which computes
1303 array[idx1,idx2...idxN], given a value array and an array
1304 of values representing indicies.
1305 values.c Changed value_from_long to work with TYPE_CODE_CHAR and
1306 unpack_long to work with TYPE_CODE_BOOL and
1309 Wed Jun 19 18:04:08 EDT 1991
1311 symtab.c Stored pervasive types in a structure and make
1312 lookup_pervasive_type() a lookup function that was based
1313 on working_lang. If lookup_pervasive_type() returned
1314 non-zero, then that value was returned (a fix, since
1315 before it simply wouldn't return the pervasive type.)
1316 language.h Added the macro CAST_IS_CONVERSION, which evaluates to
1317 non-zero if the language specified by working_lang means
1318 "conversion" when it says "cast".
1319 valops.c Added the function value_real_cast(), which performs a
1320 value.h *cast*, not a *conversion*, which is what value_cast()
1321 does when it can. In particular,
1322 value_cast(<float_type>,4) = 4.0, while
1323 value_real_cast(<float_type>,4) = some mess.
1324 eval.c Modula-2 builtin functions implemented: ABS, CAP, CHR,
1325 parser-code.c FLOAT, HIGH, MAX, MIN, ODD, ORD, TRUNC, and VAL.
1326 expression.h Added macros MAX_OF_TYPE and MIN_OF_TYPE to work with MAX
1327 and MIN on integral types. *NOTE*: These are currently
1328 hardcoded to work only if there are 8 bits per storage
1330 eval.c Made logical functions call value_bool to return a
1331 properly typed boolean value, based on working_lang.
1333 Thu Jun 20 11:55:27 EDT 1991
1335 valprint.c Types now print out in a Modula-2 fashion. This works for
1336 the cases when the type is printed out step-by-step, that
1337 is, it doesn't work when the name of a structured type
1338 (which includes the keyword "struct", etc.) is simply
1340 FIXME: Perhaps this is bad. Parts of it seem to kludgey,
1341 since type specifications in C and Modula-2 are very
1342 different. The C printing of a type is very recursive,
1343 whereas in Modula-2 it is generally very simple. C has
1344 type prefixes and suffixes, which have no real analogue in
1345 Modula-2. Maybe type_print() should call a language
1346 specific type printer. This is also advantageous if we
1347 compile GDB to exclude some of the languages. We'll just
1348 leave those functions out.
1350 Thu Jun 20 16:57:10 EDT 1991
1352 dbxread.c When reading the complete symbol table in (via
1353 psymtab_to_symtab()), the number and types of function
1354 arguments are added to a function type. define_symbol()
1355 calls add_param_to_type() to accomplish this.
1356 Assumption: when we come across a function definition
1357 (N_FUN symbol with an 'f' or 'F' in the name), its
1358 arguments will appear before another function definition.
1359 When a function is found, a pointer to its type is placed
1360 in the global in_function_type. Changes that
1361 add_param_to_type() makes are to this global.
1362 valprint.c The type of a function now includes (for Modula-2) the
1363 types of its parameters.
1364 eval.c Type checking and a check for the proper number of
1365 arguments is now done for function calls. Not sure of the
1366 impact this has on C++ member function yet.
1368 Thu Jun 20 19:58:48 EDT 1991
1370 valprint.c Rewrote the type printer. Broke it into two language
1371 specific parts, adding the functions type_print_m2() and
1373 An unfortunate consequence is this: if you debugging a C
1374 program in Modula-2 mode (why?), info types does not work
1375 well with regular expressions, since the types are printed
1376 out in Modula-2 terminology, but stored in C terminology.
1377 language.[ch] Added the functions new_type_last(), type_keyword(), and
1378 type_sep() to aid in the printing of typedefs.
1379 symtab.c Made the printing of typedefs as language independent as
1380 possible through calls to new_type_last(), type_keyword(),
1383 Fri Jun 21 11:50:26 EDT 1991
1385 dbxread.c Check all incoming ennumerated types. If it looks like
1386 Modula-2's BOOLEAN type, then change the type_code of the
1387 type to TYPE_CODE_BOOL so we can process it as a boolean
1389 valprint.c Replaced some of the 0x%x with calls to sprintf and
1390 hexformat() in val_print().
1391 language.[ch] Added the function hex_to_string(), which converts its
1392 integral argument to a hexadecimal number (format is
1393 language based) and returns the result as a string.
1395 Mon Jun 24 12:25:07 EDT 1991
1397 valprint.c Some functions call type_print_1() directly, instead of
1398 value.h using type_print(), so they can specify where (column) to
1399 print things. Since type_print() takes care of language
1400 dependence, that needs to be called first. Added a
1401 parameter depth to type_print() (so it is now like
1402 type_print_1). Changed type_print to type_print_at, and
1403 made type_print a macro that passes a depth argument of
1405 symmisc.c Changed all calls to type_print_1 to calls to
1407 Makefile.dist Made it possible to build GDB for a specific set of
1408 depend languages. Do this by passing a definition for the macro
1409 LANGS to make. LANGS should be a string containing a
1410 space-separated list of language names (ie. LANGS="c m2").
1411 The default is to build all languages. Note that grammar
1412 files must follow the naming convention of <lang>-exp.y.
1413 gdb.lang This holds the current value of the LANGS macro. It is
1414 examined every time make is called, and is updated if
1416 eval.c Added #ifdef _LANG_<lang> to these files.
1417 expread.c Still need to add them to dbxread.c and coffread.c.
1425 Mon Jun 24 16:33:11 EDT 1991
1427 language.[ch] Added the functions hexformat_pre() and
1428 hex_to_string_pre(), which take a prefix argument to
1429 include in the format string. Thus, hexformat_pre("08") will
1430 return "0x08x" (if the working language is language_c).
1431 Made hexformat() and hex_to_string() calls to the above
1432 with "" as the prefix argument.
1434 am29k-pinsn.c, arm-pinsn.c, breakpoint.c, convex-tdep.c, exec.c, core.c,
1435 dbxread.c, i386-pinsn.c, i386-stub.c, i386-xdep.c, i960-pinsn.c,
1436 infcmd.c, inflow.c, m68k-pinsn.c, m68k-stub.c, m88k-pinsn.c,
1437 mips-pinsn.c, mips-tdep.c, ns32k-pinsn.c, printcmd.c, pyr-pinsn.c,
1438 pyr-tdep.c, pyr-xdep.c, remote-vx.c, remote.c, solib.c, source.c,
1439 stack.c, sun386-xdep.c, symfile.c, symm-xdep.c, symmisc.c, tahoe-pinsn.c,
1440 valprint.c, vax-pinsn.c
1442 Changed all occurences of 0x%[0-9]*l*x in printf format strings to
1443 calls to hexformat() and hex_to_string(). Format strings without
1444 the leading "0x" were ignored.
1446 depend Updated to take the above into account.
1449 Tue Jun 25 15:27:18 EDT 1991
1451 symtab.h Added the types range_mode_t, range_check_t, type_mode_t,
1452 and type_check_t to keep track of the current state of
1453 range and type checking.
1454 main.c Added the variables range_mode, range_check, type_mode,
1455 and type_check to record the current state of range and
1456 type checking. Added initialization code to main().
1457 language.h Changed the macros STRICT_TYPE and RANGE_CHECK to examine
1458 the above variables.
1461 Tue Jun 25 17:57:08 EDT 1991
1463 dbxread.c process_one_symbol() updates the variable (enum language)
1464 source_lang based on the extension of the filename
1465 contained in the N_SO sybmol that started this symtab.
1466 When end_symtab() is called, the value of source_lang is
1467 put into the language field.
1468 stack.c select_frame() sets working_lang (and possibly type_check
1469 and range_check) to the language field of the symtab
1470 associated with the frame that is selected if working_mode
1471 is language_auto. If working_mode is language_manual, a
1472 warning is printed and working_lang is not set.
1473 language.c Added the function set_type_range(), which sets the value of
1474 type_check and range_check (if their modes call for
1475 automatic setting) based on the current value of
1476 working_lang. A non-zero argument will cause the current
1477 settings to be output.
1480 Wed Jun 26 14:51:40 EDT 1991
1482 eval.c Added range checks on assignment.
1483 m2-exp.y Added the grammar for sets to the language. Currently,
1484 these do not do anything except print an error message.
1486 Wed Jun 26 17:01:04 EDT 1991
1488 m2-exp.y Added the ability for parse_number() to parse negative
1489 numbers. A global flag is set upon encountering a unary
1490 minus. This was done to make, for example, 1 parse as a
1491 CARDINAL, and not as an integer, per Wirth's examples in
1492 Programming in Modula-2 ed.4.
1493 valprint.c Added support for "set radix 2" by then setting
1494 output_format to 't'.
1495 eval.c Implemented range checking on subrange types. Added calls
1496 to range_check_range_p for BINOP_ASSIGN and BINOP_VAL.
1497 Implemented MIN and MAX for ennumerated types. The
1498 minimum value of an ennumerated type is defined by Wirth
1499 as the first identifier, and the maximum as the last.
1500 m2-exp.y Made octal numbers ending with "B" be characters and those
1501 ending with "C" be numbers, per Wirth's book. (p. 34)
1503 Thu Jun 27 14:11:52 EDT 1991
1505 stack.c select_frame() now only sets working_lang, it does not
1506 notify the user. If working_mode is language_manual, then
1507 a warning is issued once.
1508 main.c At the end of each call to execute_command(), working_lang
1509 is checked against the local static (enum language)
1510 current. If they differ and working_mode is
1511 language_auto, the new settings of language, type and
1512 range checking are printed out.
1513 stack.c Modified frame_info() to include the language of the
1514 current frame in the output of "info frame".
1515 language.[ch] Added the function language_str() which returns the name
1516 of the current language.
1518 Fri Jun 28 15:33:14 EDT 1991
1520 m2-exp.y Added the built-in procedures INC, INCL, DEC, and DECL to
1521 the language. INCL and DECL currently cause an error,
1522 since sets are not implemented yet. INC and DEC are
1523 implemented as PREINCREMENT/PREDECREMENT with one
1524 argument, and as ASSIGN_MODIFY with two arguments.
1525 eval.c Added type checking to the above cases.
1526 value.h Added not_lval_constant to the lval_type ennumerated type.
1527 not_lval_constant means that the value is a constant
1528 value; that is 3 or 'a' or TRUE, not as in a constant
1529 identifier. This is used to help coerce numbers such as 3
1530 to either signed or unsigned numbers.
1531 valops.c Added the function value_coerce_constants() which coerces
1532 constant integers as following: if one is a constant and
1533 the other is not, the constant's type is set to the type
1534 of the other argument. If both are constants and one is
1535 signed, the other is converted to a signed constant.
1537 Sat Jun 29 17:26:29 EDT 1991
1539 valarith.c Added a better range checker. It now checks range
1540 (successfully) on integral operations [+-] (signed and
1541 unsigned) for any C sized type. Still does not work well
1542 for multiplication.)
1543 int_in_size() returns an integer that is coerced to fit into
1544 specified number of bytes.
1546 Mon Jul 1 13:04:14 EDT 1991
1548 language.[ch] Added the function binop_result_type(), which returns the
1549 builtin (struct type *) type that would be the result of a
1550 binop on the two values V1 and V2.
1552 Wed Jul 3 19:22:53 EDT 1991
1554 source.c Extended source_info() to include the source language in
1555 the output from "info source".
1557 Fri Jul 5 13:48:52 EDT 1991
1559 utils.c Moved the support functions for the GDB set/show commands
1560 dealing with language into language.c.
1561 language.c Added the function language_info(), which displays info
1562 about the current working language, type and range check
1563 settings. Called via the GDB command "info language".
1564 Added an initialization routine _initialize_language(),
1565 that sets defaults for the language, type and range
1566 variables and sets up the new GDB commands.
1567 main.c Language setup moved to language.c.
1570 Mon Jul 8 10:10:22 EDT 1991
1572 valarith.c Debugged the range checker for arithmetic. Still does not
1573 work for multiplication very well.
1575 Mon Jul 8 12:40:37 EDT 1991
1577 language.[ch] Added the function value_true() which returns non-zero if
1578 its argument represents a boolean true value.
1579 breakpoint.c Changed breakpoint_cond_eval() to call value_true() to
1580 check the truth of an expression.
1582 Thu Jul 11 12:51:34 EDT 1991
1584 language.[ch] Added the predicate structured_type(), which returns
1585 non-zero if the argument is a structured type.
1586 Added the predicate pointer_type(), which returns non-zero
1587 if the argument is a pointer type.
1588 eval.c Added the ability to do addition and substraction on
1589 pointers and integers. This case simply bypasses the
1592 Thu Jul 11 14:41:42 EDT 1991
1595 Added the symbol N_DEFD (0x4a) which is a definition
1596 module dependency that is used by the GNU Modula-2
1597 compiler and the linker. It is not important to GDB,
1598 except that [dbx|coff|mips]read.c should ignore these
1601 Fri Jul 12 16:07:00 EDT 1991
1603 valprint.c Changed the TYPE_LENGTH(type) >= 0 to TYPE_LENGTH(type) >
1604 0 in val_print(). Also added statements to the else part
1605 to coerce type (argument to val_print) to a pointer type
1606 if it is an "array of unspecified length".
1607 valops.c Added the function value_m2_string(), which returns a
1608 (value) value which is a constant string, whose type is
1609 (ARRAY [0..n] OF CHAR). The length field of the type
1610 structure is set to zero, so it will be interpreted as an
1611 "array of unspecified length".
1612 stack.c Moved the language/frame mismatch check to
1613 main.c:execute_command().
1614 main.c The working language is recorded each time
1615 execute_command() is executed. If working lang has
1616 changed during its execution, then the new
1617 language/type/range info is printed out for the user. If
1618 the working language does not match the language of the
1619 frame, a warning is issued.
1621 Sat Jul 13 16:16:39 EDT 1991
1623 eval.c Moved all the type-checking stuff for operators to
1624 language.[ch] language.c. This is so we can keep language-specific
1625 stuff (like for what type operators are defined) in
1627 language.[ch] Added the function binop_type_check(), which checks to see
1628 if its two (value) arguments are type-compatible with its
1629 opcode argument. The opcode should represent an operation
1630 involving an operator. Also added the macro function
1631 unop_type_check, which calls binop_type_check with a
1632 NULL second argument.
1633 expprint.c Added Modula-2 operators to the op_print_tab, so info
1634 expression.h break works correctly. Also added "op_string", which
1635 returns the string corresponding to the (enum exp_opcode)
1636 opcode that is its argument.
1639 Sat Jul 13 18:26:18 EDT 1991
1641 coffread.c Added code to record the type of function arguments with
1642 each paricular function. Code is very similar to that
1644 dbxread.c Moved add_param_to_type() to symtab.c
1645 symtab.[ch] Added function add_param_to_type() from dbxread.c
1647 *** NOTE: The above additions have not been tested.
1649 Mon Jul 15 12:50:47 EDT 1991
1651 langauge.[ch] Added the functions type_error and range_error, which work
1652 like error() except if the type/range mode is set to
1653 *_mode_warn, then they do not do a return_to_top_level(),
1654 but merely print a warning.
1655 Also changed [set|show]_[type|range]_command() to support
1656 the new "warn" feature.
1658 Thu Jul 18 17:50:54 EDT 1991
1660 mipsread.c Added code to record the type of function arguments with
1661 each particular function. Code is very similar to that
1664 *** NOTE: The above additions have not been tested.
1666 Fri Jul 19 11:19:10 EDT 1991
1668 defs.h Added macros MAX_OF_SIZE, MIN_OF_SIZE, UMAX_OF_SIZE, and
1669 UMIN_OF_SIZE, which when given a size of a numeric type,
1670 return the maximum and minimum value it can hold. UMAX...
1671 and UMIN... return the result for unsigned types.
1672 symtab.h Added the macros MAX_OF_TYPE and MIN_OF_TYPE to operate on
1673 struct types. They call above macros.
1674 dbxread.c Renamed the MAX and MIN_OF_TYPE macros to ..._OF_CTYPE to
1675 avoid a name conlict with the above.
1676 c-exp.y Added range checking on numeric constants in
1677 parse_number() for completeness.
1678 valarith.c Made binop_user_defined_p() and unop_user_defined_p()
1679 return 0 if working_lang is not language_c.
1681 Thu Aug 8 14:17:22 EDT 1991
1685 breakpoint.c Documentation strings of some commands changed to
1686 eliminate the references to the C language where
1689 Tue Aug 13 15:48:03 EDT 1991
1691 m2-exp.y Added qualified identifiers to the grammar. The semantics
1692 are slightly different from those of the GDB operator ::
1694 m2-exp.y Added a rule to each grammar of the form: start ::= exp |
1695 type_exp, where type_exp is any valid type expression.
1697 eval.c Added the opcode OP_TYPE, and an error case in eval.c.
1698 printcmd.c Modified ptype_command() so it actually parses the input
1699 (necessary for type expressions with scope qualifiers).
1700 Added the function ptype_eval() which expects an
1701 expression composed of one OP_TYPE element.
1702 *.[ch] Replaced all occurences of parse_c_expression with
1704 *.[ch] Replaced all occurences of parse_c_1 with parse_exp_1
1706 [End of ChangeLog entries from Andrew Beers for Modula-2 support.]
1708 Mon Sep 16 17:19:46 1991 John Gilmore (gnu at cygnus.com)
1710 Small fixes from Peter Schauer:
1712 * infrun.c (child_attach): Lint.
1713 * solib.c (find_solib): Handle shared libs version 2.
1715 Small fixes from David Wood:
1717 * xm-ultra3.h (SYS_SIGLIST_MISSING): Typo.
1721 * remote-vx.c: Move <stdio.h> to top, for FILE. Fix from
1722 John S <basrai%kanga.dnet@c3po.sm-alc.af.mil>.
1724 * utils.c (wrap_here): Avoid wrap action of fputs_filtered if
1725 chars_per_line is at maximum (user typed `set width 0'). Fix
1726 from Andreas Schwab <schwab@ls5.informatik.uni-dortmund.de>.
1728 Tue Sep 17 17:31:04 1991 Stu Grossman (grossman at cygnus.com)
1730 * coredep.c: include ptrace.h where necessary.
1731 * mipsread.c(parse_lines): fix unsigned char problem that was
1732 messing up line numbers on SGI's and possibly other MIPS based
1734 * infrun.c (child_create_inferior): use better test to check
1735 return val from setpgrp().
1736 * tm-irix3.h, xm-irix3.h, tconfig/irix3, xconfig/irix3: add these
1737 for sgi/irix support.
1739 Wed Sep 18 04:33:31 1991 Per Bothner (bothner at cygnus.com)
1741 * mipsread.c (parse_symbol): Put non-static procedures
1742 in the global block.
1744 Fri Sep 13 00:14:52 1991 John Gilmore (gnu at cygnus.com)
1746 Patch together `text_start' and `text_end' for 29K port.
1748 * exec.c (exec_command): If NEED_TEXT_START_END, define the
1749 variables and set them based on the exec file.
1750 * am29k-tdep.c: declare text_start.
1751 * valops.c (call_function_by_hand): declare text_end.
1753 * inferior.h: Eliminate CANNOT_EXECUTE_STACK in favor of
1754 defining CALL_DUMMY_LOCATION as BEFORE_TEXT_END. This is
1755 because machines that do this will also have to know to
1756 set NEED_TEXT_START_END. Besides, it was a redundant way to
1758 * tm-29k.h, tm-convex.h, tm-np1.h: Eliminate
1759 CANNOT_EXECUTE_STACK, define CALL_DUMMY_LOCATION and
1760 NEED_TEXT_START_END.
1762 Thu Sep 12 00:22:24 1991 John Gilmore (gnu at cygint.cygnus.com)
1764 AMD 29000 changes from David Wood <wood@david.ultra.nyu.edu>:
1766 * Makefile.in (CLIBS): Put XM_CLIBS and TM_CLIBS at end.
1767 Pass MUNCH_DEFINE to munch whenever we run it.
1768 * am29k-pinsn.c (print_insn): Handle NOP specially. Avoid %#x
1769 format string; use 0x%x instead.
1770 * am29k-tdep.c: Use DUMMY_SAVE_GREGS and RETURN_REGNUM.
1771 * ultra-xdep.c, xm-ultra.h: New files for Ultracomputer host system.
1772 * xm-rtbsd.h: New host support for RT/PC running BSD Unix.
1773 * inflow.c: Handle `short' process group IDs.
1774 * infptrace.c (fetch_register): Support CANNOT_FETCH_REGISTER,
1775 and check for ptrace errors.
1776 * coffread.c (SDB_REG_TO_REGNUM): Define if not already.
1777 (coff_symfile_init): Initialize text_bfd_scnum.
1778 (read_coff_symtab): Use it to find the text [and absolute?] sections.
1779 * ../config.sub: Add vendor nyu and os "sym[1-9]*".
1780 * configure.in: Add hosts rtpc-*-* and a29k-*-*.
1781 Merge target arm case with other "easy" cases. Add target
1782 cases a29k-*-none (rehack of am29k), a29k-*-kern (remote to
1783 Ultracomputer kernel), and a29k-*-sym1 (ultracomputer OS's user
1785 * minimon.h, remote-adapt.c, remote-mm.c: Add.
1786 * munch: Cope with RT/PC putting fns in data segment.
1787 Restore ability to override `nm' by specifying MUNCH_NM.
1788 * xconfig/rtbsd, xconfig/ultra3: New host systems.
1789 * tconfig/a29k: Rename from tconfig/am29k. Add remote-mm
1790 and remote-adapt. Remove encapsulated coff #define's (the
1791 support should go in BFD, and gdb shouldn't know or care).
1792 * tconfig/a29k-kern: Same, but for remote kernel debugging.
1793 * tconfig/ultra3: For debugging user processes on Ultra3/Sym1.
1794 * tm-29k.h: Update BADMAG (though it should go away).
1795 Allow the register definitions to be overridden in another
1796 tm-file. Fix SR_REGNUM. Add a mess of _REGNUM's. Separate
1797 RETURN_REGNUM from GR96_REGNUM and DUMMY_SAVE_GREGS from
1798 DUMMY_SAVE_GR96, for handling kernel calling conventions
1799 that use GR64+ rather than GR96+.
1800 * tm-ultra3.h: New file, for use on Ultra3 Unix as well as for
1801 remote debugging of Ultra3 kernel. Includes tm-29k.h and
1802 overrides various things.
1804 * remote-mm.c (mm_attach, mm_wait): Handle attach like
1805 child_attach does, making a clean stop in the newly attached
1807 * remote-eb.c: Lint.
1809 * coffread.c: Make coffread independent of any particular
1810 variant of COFF. Avoid #include-ing any particular one except
1811 internalcoff.h. BFD now passes key values for symbol reading
1812 as part of its coff_data structure (LINESZ, SYMESZ, AUXESZ,
1813 and the symbol masks and shifts); use them.
1814 Remove obsolete end_of_text_addr.
1816 * exec.c: Remove unused include files.
1818 Wed Sep 11 19:38:44 1991 John Gilmore (gnu at cygint.cygnus.com)
1820 * Makefile.in (documentation targets): Pass $(M4).
1821 Bugfix from eggert@twinsun.com (Paul Eggert).
1823 * stack.c (down_silently_command): Check for stack existence.
1825 Tue Sep 10 23:08:29 1991 John Gilmore (gnu at cygint.cygnus.com)
1827 * Makefile.in (VERSION): Update to 4.0.3.
1829 Tue Sep 10 09:19:29 1991 John Gilmore (gnu at cygint.cygnus.com)
1831 * core.c (core_file_command): Print frame at coredump with
1832 its level number, by calling print_stack_frame.
1833 * frame.h: Add selected_frame_level, print_stack_frame.
1834 * frame.h, stack.c: Remove print_sel_frame, print_selected_frame.
1835 * convex-tdep.c, convex-xdep.c, infcmd.c, inflow.c, infrun.c:
1836 Change print_sel_frame and print_selected_frame callers to
1839 * dbxread.c (read_ofile_symtab): Avoid empty else clause.
1840 * symfile.c (free_named_symtabs): Ditto.
1841 * main.c (main): wrap_here needs an arg.
1842 * solib.c (find_solib): Avoid memory access if _DYNAMIC is zero.
1843 (solib_add): Avoid noise.
1844 (solib_create_inferior_hook): Lint.
1845 (sharedlibrary_command): Move dont_repeat to here.
1846 * utils.c (error): Call wrap_here to force buffered output.
1848 Small patches from Peter Schauer:
1850 * coffread.c (start_symtab): Free any existing line_vector before
1852 (read_coff_symtab): Ditto for type_vector.
1854 * source.c (lines_to_list): New variable, replacing function.
1855 (all uses): Use as variable.
1856 (_initialize_source): Add 'set listsize' and 'show listsize'.
1857 * utils.c (lines_to_list): Remove function.
1858 * stack.c (print_frame_info): Use as variable.
1859 * defs.h (lines_to_list): Remove declaration.
1861 Mon Sep 9 13:45:57 1991 John Gilmore (gnu at cygint.cygnus.com)
1863 * breakpoint.c (insert_breakpoints): Restore warning about
1864 the program might be running in another process, but only for
1865 systems with this brain death (#ifdef ONE_PROCESS_WRITETEXT).
1866 * xm-hp300bsd.h, xm-mips.h, xm-vax.h: Define it.
1868 * utils.c (error): if error_pre_print is set, print the string
1870 * main.c (main, print_gnu_advertisement, print_gdb_version):
1871 Reformat legalese so it always prints, but acts as an "I'm here"
1872 message while symbols are being read. If any errors occur,
1873 print a few newlines to set off the message and start it at the
1874 left margin. Remove mention of "help" command, and don't yak
1875 about symbol reading.
1876 (catch_errors): Error string is now printed first in case of
1878 * command.c (undef_cmd_error, lookup_cmd): On undefined command,
1879 suggest the "help" command.
1881 * Makefile.in (VERSION): Set to 4.0.2.
1883 Thu Sep 5 23:49:48 1991 John Gilmore (gnu at cygint.cygnus.com)
1885 * .gdbinit: Remove useless "rr" command. Set complaints
1886 to 1 for people debugging gdb.
1888 * breakpoint.c, remote-vx.c: Reword strings printed by
1889 catch_errors callers.
1891 Wed Sep 4 11:07:50 1991 John Gilmore (gnu at cygint.cygnus.com)
1893 * WHATS.NEW: "history write -> history save". Doc "write on/off".
1894 (Fix from kenc@viewlogic.com.)
1896 Fix some infrastructure to be able to cope with host and target
1897 machines with different sized basic types (ints, ptrs, etc).
1898 (Idea from pierre@la.tce.com (Pierre Willard).)
1900 * values.c (value_from_longest): Rename from value_from_long.
1901 Handle pointer types as well as integers, so that targets with
1902 different pointer sizes from the host can be accomodated.
1903 * breakpoint.c, convex-tdep.c, eval.c, expprint.c, printcmd.c,
1904 valarith.c, valops.c, valprint.c, value.h, values.c: Rename
1905 uses of value_from_long to value_from_longest.
1906 * eval.c, findvar.c, printcmd.c, valarith.c, valops.c: Pass
1907 the correct pointer type to value_from_long{est}.
1909 * doc/gdb.texinfo ($_, $__): Describe types of these variables.
1911 * remote-vx.c: Remove obsolete code for calling functions via
1912 vxworks kludge interface (it referenced value_from_long).
1914 * valops.c (value_string): Find malloc with lookup_misc_func, not
1917 Tue Sep 3 18:37:46 1991 John Gilmore (gnu at cygint.cygnus.com)
1919 Make writing to files work properly. (Fixes to BFD are also needed.)
1921 * core.c (core_open): Open file ourselves, read or r/w, depending on
1922 write_files. Use bfd_fdopenr.
1923 * gdbcore.h (write_files): New variable.
1924 * exec.c (write_files): Define variable, add set&show for it.
1925 (exec_file_command): Use write_files to open for read or r/write.
1927 Make shared library reading happen automatically. These changes
1928 are mostly from Peter Schauer <pes@regent.e-technik.tu-muenchen.de>.
1930 * inferior.h (stop_soon_quietly): Add to exported variables.
1931 * infrun.c (child_create_inferior): call solib hook, if defined.
1932 (child_attach): call solib hook, if defined.
1933 * solib.c: Include inferior.h. Add from_tty to so_list as kludge.
1934 (find_solib): Use lookup_misc_func rather than hand-rolled.
1935 (symbol_add_stub): New stub for catch_errors.
1936 (solib_add): Avoid output if !from_tty. Catch errors rather
1937 than just calling symbol_file_add and bombing.
1938 (solib_create_inferior_hook): Interface with the target process
1939 to let it read and alloc shared libs, then figure out what it did.
1941 * core.c (validate_files): Fix typo, soften warning.
1942 (Fix from Hiroto Kagotani <kagotani@cs.titech.ac.jp>.)
1944 * utils.c (fputs_demangled): Avoid duplicate printing if
1945 demangling is off. (Fix from J.T. Conklin <jtc@cayenne.com>.)
1947 * infrun.c (proceed): Cast -1 to (CORE_ADDR) before comparing.
1948 (Fix from pierre@la.tce.com (Pierre Willard).)
1950 * main.c (catch_errors): Change argument to a char * from an int,
1951 since a char * can point to a struct full of glop, but an int
1952 is not guaranteed to be able to hold a pointer.
1953 * breakpoint.c (breakpoint_cond_eval, bpstat_stop_status,
1954 breakpoint_re_set_one, breakpoint_re_set): Adapt.
1955 * core.c (core_open, solib_add_stub): Adapt.
1956 * remote-vx.c (symbol_stub, add_symbol_stub, callers): Adapt.
1958 Wed Aug 28 18:18:05 1991 John Gilmore (gnu at cygint.cygnus.com)
1960 * Makefile.in: Update VERSION to 4.0.1. Evade GNU Make bug
1961 by adding .NOEXPORT target.
1963 Fri Aug 23 17:14:25 1991 John Gilmore (gnu at cygint.cygnus.com)
1967 * Makefile.in (VERSION): Roll to 4.0.
1968 (gdb.tar.Z): Make refcard.ps as well, for shipment.
1970 Fri Aug 23 14:07:09 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1972 * doc/gdb.texinfo: minor rewordings, crossref to ptype from print,
1975 * doc/Makefile, Makefile.in: generate "gdb-all.texi" rather than
1978 * doc/rdl-apps.texi: renamed from rdl-apps.texinfo
1980 * Makefile.in, doc/Makefile, doc/.Sanitize, doc/gdb.texinfo:
1981 reflect above name change
1983 * WHATS.NEW: correct pointer to refcard.
1985 * doc/gdb.texinfo: update New Features, Installing
1987 * doc/gdbint.texinfo: add short description of configure +template
1989 Fri Aug 23 11:46:08 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1991 * doc/gdb.texinfo: update, fix bugs in "Installing" appendix
1993 Fri Aug 23 01:02:00 1991 John Gilmore (gnu at cygint.cygnus.com)
1995 * Makefile.in: Add config.sub, make doc/rdl-apps.texinfo for
1996 tar file, add dependencies for referenced doc files.
1998 Thu Aug 22 22:17:06 1991 Stu Grossman (grossman at cygint.cygnus.com)
2000 * coffread.c, symfile.c, stack.c: saberized.
2002 Thu Aug 22 16:20:27 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
2004 * doc/refcard.tex: permuted Essential Commands sec
2006 * doc/gdb.texinfo: new C++ chapter; revised installation appendix;
2008 set/show symbol-reloading
2009 default set complaints 0
2011 RET-repeat disabled after prompted long displays
2012 processID (attach) interpretation of 2nd GDB cmdline arg
2014 Thu Aug 22 14:05:47 1991 Stu Grossman (grossman at cygint.cygnus.com)
2016 * expread.y, coffread.c, dbxread.c, target.c, mem-break.c,
2017 cplus-dem.c, values.c, valprint.c, symfile.c, remote.c,
2018 breakpoint.c, main.c: lint.
2020 Thu Aug 22 02:02:26 1991 John Gilmore (gnu at cygint.cygnus.com)
2022 Install new configuration scheme for GDB and friends.
2024 * config.sub: Translate ordinary names to three-part names.
2025 * configure: Use three-part names internally.
2026 * configure.in: Translate three-part names to filenames.
2028 * README, WHATS.NEW: Update for gdb-4.0.
2029 * Makefile.in: Roll VERSION to 3.99.
2031 Wed Aug 21 18:21:09 1991 John Gilmore (gnu at cygint.cygnus.com)
2033 * infptrace.c (KERNEL_U_ADDR_BSD): Include a.out.gnu.h.
2034 * i960-tdep.c, m68k-tdep.c, sparc-tdep.c, tm-i960.h,
2035 tm-m68k.h, remote-nindy.c: Change ext_format_XXX structs
2036 to single structures rather than arrays; when passing
2037 their address, use &. This avoids trouble with bdead compilers.
2038 * mcheck.c: Don't include <stdlib.h>; just declare "void abort();"
2039 instead. This avoids portability headaches.
2040 * mips-tdep.c (mips_do_registers_info): Only print FP regs if
2042 * source.c (open_source_file): Avoid ANSI const bdeath by
2043 skipping declaration and then casting result value.
2044 * tm-hp300bsd.h: Clarify comment.
2045 * utils.c (strstr): Result is const char *; ANSI bdeath.
2046 * xm-hp300bsd.h: Define HOST_BYTE_ORDER. Redefine INT_MIN,
2047 since system include file defines it differently from "defs.h",
2048 though the two are equivalent for our purposes.
2049 * tconfig/hp300bsd: Add m68k-tdep.o.
2051 Tue Aug 20 16:01:11 1991 John Gilmore (gnu at cygint.cygnus.com)
2053 * tconfig/sun*4: Remove warnings about system assembler.
2055 Mon Aug 19 13:44:46 1991 John Gilmore (gnu at cygint.cygnus.com)
2057 * mcheck.c: Avoid warning about undeclared abort fn.
2058 * tm-sparc.h (PC_ADJUST): Avoid calling error() from this;
2059 it causes recursive calls to error() when used in cleanups.
2060 To do so requires that we make it a function, so we do.
2061 * sparc-tdep.c (sparc_pc_adjust): New implem of PC_ADJUST.
2062 * utils.c (do_cleanups): Remove the current cleanup from the
2063 chain *before* calling it, in case error() is called from it.
2064 The result won't be pretty, but won't be an infinite loop either.
2066 Mon Aug 19 00:41:04 1991 Michael Tiemann (tiemann at cygint.cygnus.com)
2068 * dbxread.c (read_struct_type): Grok anon structs for C++.
2069 (vb_name, vptr_name): Null terminate these strings.
2071 Fri Aug 16 08:31:03 1991 John Gilmore (gnu at cygint.cygnus.com)
2073 Minor bug fixes from BSD Net2 gdb:
2075 * blockframe.c (get_prev_frame_info): If FRAME_CHAIN_COMBINE
2076 returns 0, there is no previous frame.
2077 * breakpoint.c (commands_command): If !from_tty, don't call
2078 input_from_terminal_p().
2079 * dbxread.c (record_misc_function): Speed up slightly.
2080 (compare_psymbols): Ditto.
2081 * infcmd.c (do_registers_info): Take a second argument to
2082 determine whether to print float registers. "info registers"
2083 does not do so anymore. "info all-registers" does, now.
2084 * mips-tdep.c, pyr-tdep.c (xxx_do_registers_info): Take second
2086 * tm-mips.h, tm-pyr.h (DO_REGISTERS_INFO): Pass second arg.
2087 * inflow.c (initialize_inflow): Set tflags_ours correctly.
2091 * breakpoint.c (bpstat_do_actions): Use a cleanup to restore
2092 executing_breakpoint_commands if we are interrupted by error.
2093 * coffread.c (init_lineno): Avoid problem with zero-sized linetab
2094 versus malloc/free. From: john@labtam.labtam.oz.au (John Carey).
2095 * core.c (solib_add_stub, core_open): Call SOLIB_ADD inside a
2096 catch_errors() so we can setup the frame regardless of whether
2097 the shared libs work.
2098 * ieee-float.c (double_to_ieee_extended): Get exponent from
2099 right place in little-endian systems. From John Carey.
2101 Thu Aug 15 18:43:57 1991 John Gilmore (gnu at cygint.cygnus.com)
2103 * main.c: Remove unused terminating_signals and catch_termination().
2104 (long_options): Terminate with a zero element.
2105 [Bugfix from Atsuo Kawaguchi <atsuo@hark86.harl.hitachi.co.jp>.]
2106 (gdb_readline): Make call-compatible with readline.
2107 (init_signals): Improve comments re vfork vs. signal.
2109 * utils.c (prompt_for_continue): Use new gdb_readline().
2110 If we prompt for continuation, we don't let CR repeat the previous
2111 command, once we get back to a prompt. It's too easy to keep
2112 hitting CR, expecting "--more--" prompts, and have some long
2113 command start repeating on you.
2115 Tue Aug 13 16:17:56 1991 John Gilmore (gnu at cygint.cygnus.com)
2117 * blockframe.c (frameless_look_for_prologue): Speed up by
2118 calling SKIP_PROLOGUE_FRAMELESS_P if it's defined.
2119 * tm-sparc.h (SKIP_PROLOGUE, SKIP_PROLOGUE_FRAMELESS_P):
2120 Define two variants, one faster.
2121 * sparc-tdep.c (sparc_frame_chain): Use target_read_memory
2122 and return zero, rather than giving an error.
2123 (setup_arbitrary_frame): Initialize the PC in the new frame.
2124 (skip_prologue): Add a second arg saying whether we're just
2125 checking for a frameless function or not.
2127 * core.c (core_open, core_close, core_xfer_memory): Move
2128 section table pointers and bfd* into the target_ops.
2129 (core_open): Allow errors in shared lib reading, etc.
2130 (core_files_info): Describe shared library sections.
2132 * exec.c (exec_open, exec_close, exec_xfer_memory, xfer_memory,
2133 exec_files_info, set_section_command): Move section table
2134 pointers and bfd* into the target_ops.
2135 (add_to_section_table): Add BFD to section table.
2137 * target.c (target_xfer_memory, target_info): Pass target to
2138 xfer_memory and target_info functions.
2141 * gdbcore.h: Move struct section_table.
2142 * target.h: New home of struct section_table.
2144 * solib.c (solib_add): New argument is the target_ops whose
2145 section list is to be added to, if any. Reallocate the
2146 sections in that target to add any that come from shared libs.
2147 (throughout) so_sections renamed to sections.
2148 (solib_xfer_memory): Deleted.
2149 * tm-sunos.h (SOLIB_ADD): Add target argument.
2150 (SOLIB_XFER_MEMORY): Delete.
2152 * core.c, exec.c, inftarg.c, remote-eb.c, remote-nindy.c,
2153 remote-vx.c, remote.c, target.c, target.h: Remove add_syms vector
2154 from target_ops. It's the same on all targets. Add two section
2155 pointers to target_ops.
2157 * stack.c (find_relative_frame): Dump ancient algorithm for
2158 "down", just use handy "next" pointers.
2159 (frame_command): Don't error if there is no stack; let user
2162 * inflow.c (new_tty_prefork, new_tty): New prefork routine
2163 modifies static state in the parent process; new_tty itself
2164 runs in the child and modifies the child's file descriptors
2165 to match the saved static state.
2166 * infrun.c (child_create_inferior): Call new_tty_prefork,
2169 * infptrace.c (child_xfer_memory): Add ignored target arg.
2170 * remote-eb.c (eb_xfer_inferior_memory): ''
2171 * remote-nindy.c (nindy_xfer_inferior_memory): ''
2172 * remote-vx.c (vx_xfer_memory): ''
2173 * remote.c (remote_xfer_memory): ''. Rename from
2174 remote_xfer_inferior_memory.
2176 * main.c (main): Only try to attach "corefile" argument if
2177 it starts with a digit.
2179 * symfile.c (symbol_reloading): New "set/show" variable.
2180 (symbol_file_add): Shorten message about symbol reading.
2181 (add_symbol_file_command): Merge with add_syms_addr_command,
2182 since this should work on all targets now.
2183 (stop_whining): Default to zero, to shut up complaints
2184 about bad symbol tables on many systems.
2185 (free_named_symtabs): Just exit unless symbol_reloading.
2187 * xm-sun3os4.h, xm-sun4os4.h: Define BROKEN_LARGE_ALLOCA,
2188 and add comment explaining shared library screw.
2190 * source.c: #if defined => #ifdef.
2192 Thu Aug 8 12:23:19 1991 John Gilmore (gnu at cygint.cygnus.com)
2194 * doc/gdbint.texinfo: Improve doc on porting to new OS's.
2196 Tue Aug 6 17:16:15 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
2198 * doc/rdl-apps.texinfo: provide default readline-appendix finder
2199 (doc/Makefile knows how to make one for local config)
2201 * Makefile.in: use doc/Makefile for doc targets
2203 * doc/Makefile: GDB documentation now has its own Makefile
2204 doc/refcard.tex: renamed from "gdbrc.tex"
2205 doc/.Sanitize: add Makefile; recognize renamed refcard.tex
2206 doc/gdbint.texinfo: add markup in "Cleanups" chapter
2209 Fri Aug 2 00:13:06 1991 John Gilmore (gnu at cygint.cygnus.com)
2211 * values.c (baseclass_addr): When reading target memory, use the
2212 length of the basetype, not the upper type. We've only malloc'd
2213 enough space for the basetype, leading to errors in free().
2215 * expprint.c (print_subexp): Print UNOP_MEMVAL of an OP_LONG that
2216 ends up as a function specially, since we know the actual type of
2217 the pointed-to address. This (somewhat) fixes display of
2218 expressions that include misc_function_vector names. Try `cond 1
2219 !strcmp("a","b")' then `i b'.
2221 * infrun.c: Move DO_DEFERRED_STORES from proceed() to resume().
2222 The child can be proceeded from inside wait_for_inferior in
2223 evaluating breakpoint conditions, and DO_DEFERRED_STORES was
2224 getting skipped in that case.
2226 * expprint.c (print_subexp): Use filtered output, since the
2227 subroutines we call use it, otherwise the output is horribly
2228 mangled, since output of wrappable stuff comes out late.
2230 * Makefile.in: Bump VERSION to 3.98.1
2232 * infrun.c (child_create_process): Use execlp to find the
2233 shell to exec our target program. This requires some fiddling
2234 with `environ' since there is no execlpe().
2236 Thu Aug 1 15:35:17 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
2238 * Makefile.in, doc/gdbrc.tex, doc/rc-* (new files):
2239 Minor rearrangement of refcard permits two new make targets--
2240 gdbrc.dvi DVI output for refcard, using CM fonts
2241 gdbrc.ps PostScript refcard, using PS fonts
2243 Wed Jul 31 16:46:21 1991 John Gilmore (gnu at cygint.cygnus.com)
2247 * TODO, Projects, WHATS.NEW, README: Update for gdb-3.98.
2248 * Makefile.in (gdb-all.texinfo): Avoid touching file if M4 dies.
2250 Wed Jul 31 16:35:58 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
2252 * doc/gdb.texinfo: last changes for release.
2253 Minor typo and formatting fixes; incorporated most fixes remaining from
2254 filed mail commenting on earlier drafts.
2256 Added warnings: pipes don't work in run command;
2257 conditions are converse of assertions;
2258 step over fn without debug info goes to next fn;
2259 vars may have "wrong" values near fn entrance, exit
2261 Added example from Kingston on printing repeated nonadjacent values
2263 Added explicit mention that in Emacs gdb mode C-c and C-z are like
2264 shell mode for signals
2266 Renamed "Stepping and Continuing" to "Continuing and Stepping" so it
2267 doesn't sound so much like its parent "Stopping and Continuing"; also
2268 moved entries on continue to top of section, so they don't get lost.
2270 Improved installation directions in appendix, added manual formatting
2273 Tue Jul 30 17:26:39 1991 John Gilmore (gnu at cygint.cygnus.com)
2275 * configure.in: Remove xm.h and tm.h even if we aren't linking
2276 new ones, so "./configure sun4; ./configure none" does the right
2277 thing. Assume that alldeps.mak and depend are already built in
2278 srcdir, and avoid running "make" (particularly "make depend",
2279 which involves "gcc") from inside configure. Build Makefile
2280 directly rather than building Makefile.conf first.
2281 * configure: Regenerate with above changes.
2282 * Makefile.in: Use $(BISON) to find bison. Roll VERSION
2283 to 3.98. Revise gdb.tar.Z procedure to produce a file
2284 called gdb-$(VERSION).tar.Z but which unpacks into a
2285 directory called "gdb". Move non-source files out of
2286 $(SFILES_SUBDIR). Pretty up alldeps.mak with comments.
2287 (depend): Don't try to do "gcc expread.y".
2288 (expread.o): Update dependencies by hand.
2290 Mon Jul 29 15:21:09 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
2293 Fixed a variety of small typos that prevented info from formatting
2294 cleanly; altered too-long heading for GPL Appendix, as discussed
2295 w/RMS; Changed date on cover to July 91.
2297 Fri Jul 26 13:20:02 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
2300 (1) Applied some fixes due to comments from Larry Breed (easier ones
2301 through chapsec 5.2)
2302 (2) Eliminated use of @footnote---had my doubts about it anyways, and
2303 it's broken in latest texinfo
2304 (3) Introduced *some* use of [] for optional arguments, where
2305 explanation is not simpler by listing cmd w arg and cmd w/out arg
2306 separately. Still not using @deffn.
2307 (4) Dropped in GPL-2. NOTE: one of GPL-2 or texinfo is broken; a
2308 couple of headings are too long. Need patches to texinfo or revision
2311 * Partial update to README (which still needs work for this
2312 release!): (1) use of configure corrected for new script,
2313 (2) "make gdb.dvi" and "make gdb.info" mentioned.
2315 Wed Jul 24 06:44:02 1991 John Gilmore (gnu at cygint.cygnus.com)
2317 * symtab.c (lookup_symbol): Don't complain right off about
2318 no debug symbols; use the misc function vector first.
2319 (list_symbols): Use misc function vector to find symbols
2320 that don't have debug info, and print them.
2321 (find_pc_symtab): Temporarily avoid fatal() when psymtab
2322 PC range doesn't match symtab PC range, as it does on the
2323 MIPS because our symtab reading isn't perfect.
2325 * dbxread.c (dbx_symfile_read): Make warning about
2326 "no debug symbols" slightly nicer.
2328 * source.c (select_source_symtab): If "main" symbol exists,
2329 but decode_line_spec can't find line info, don't just return
2330 a zero; try other source symtabs or give an error.
2332 * mipsread.c (parse_partial_symbols): Sort the psymtabs by
2333 their low addresses first, then rip through fixing high addrs.
2335 * ns32k-opcode.h (sfsr): Bugfix from Rune Nerg}rd,
2336 <runene@ifi.uio.no>.
2337 (NS32K_SVC_IMMED_OPERANDS): Reverse the #ifndef.
2339 Tue Jul 23 18:52:43 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
2341 * Minor, mostly mechanical, cleanup of doc subdir for clean
2342 makeinfo'ing and TeXing; also ensured gdb-all.texinfo (post-m4)
2343 and gdb.info (post- texinfo2 makeinfo) generated for distribution.
2345 Sun Jul 21 03:54:52 1991 John Gilmore (gnu at cygint.cygnus.com)
2347 Mostly MIPS and general symbol-reading fixups.
2349 * doc/gdbint.texinfo: Add documentation on symbol-reading
2352 * mipsread.c: Remove kludges around #include "ecoff.h".
2353 Remove redefinitions of a_magic, etc, no longer used.
2354 (parse_symbol, ): Convert "Internal:" printfs to complain()ts.
2355 Fix global overview comments to match symfile.c protocol.
2356 (mipscoff_new_init): Eliminate cur_hdr if we have one.
2357 (mipscoff_symfile_read): Eliminate unused code. Avoid
2358 sorting all the symtabs, when all we have read here is psymtabs.
2359 The symtabs are sorted as they are created anyway. Tell
2360 condense_misc_bunches whether we're mainline.
2361 (psymtab_to_symtab_1): Pass filename when recursing, to make
2362 stack trace more informative.
2363 (parse_partial_symbols): Assume cur_hdr as argument.
2364 (read_mips_symtab): Don't clobber cur_hdr, so it can be freed.
2365 Pass cur_hdr implicitly to parse_partial_symbols. Avoid checking
2366 the TYPE_NAME of char *, since that's done in symfile.c.
2367 (free_numargs, parse_symbol, add_symbol, add_block,
2368 shrink_linetable): Declare these fns void.
2369 (upgrade_type): Convert tree of if's to switch. Clean up
2370 bogus "off == 0" handling with a complaint. Avoid setting
2371 field bitpos and bitsize of array with lower and upper bounds.
2372 Check specified bitsize of elements against their actual type's
2373 bitsize, and complain if different. Complain about unknown
2375 (parse_fdr): Don't assume sizeof(char *) == sizeof (struct *).
2376 (psymtab_to_symtab_1): Print names of subsidiary files that
2377 are being read in. FIXME, we read far too many files. This code
2378 is not the problem, the problem is in parse_fdr where the psymtabs
2380 (cross_ref): Result should indicate that we used one aux entry
2381 normally, or two if we encountered a "next" entry. This used
2382 to leave the caller pointing at the wrong aux entry.
2383 (add_symbol): If overflowed cur_block, reallocate it larger,
2384 chase all pointers to it, and complain(), rather than clobber memory.
2385 (shrink_block): Use xrealloc rather than xmalloc-and-copy.
2386 (new_field): Only allocate one field initially, not two.
2387 Pull ++ out of macro argument. Simplify.
2388 (_initialize_mipsread): Avoid initialization of importd
2389 global_psymbols and static_psymbols.
2391 * symfile.c (psymtab_to_symtab): Depend on XXX_psymtab_to_symtab
2392 to properly set pst->symtab; avoid searching for it.
2393 (symfile_fns): Improve comments, add a FIXME.
2394 * dbxread.c: Update comments to reflect symfile protocol.
2395 (read_ofile_symtab, end_symtab): Return the symtab.
2396 (psymtab_to_symtab_1): Set pst->symtab.
2398 * coffread.c (coff_symfile_read): tell condense_misc_bunches
2399 whether we're mainline.
2401 * symfile.h (sym_fns): Remove unused sym_discard member.
2402 * coffread.c, mipsread.c, dbxread.c: Remove XXX_symfile_discard.
2404 * mtrace.c (mtrace): Take effect if mallwatch is set, even if
2405 the environment variable is not.
2406 * infcmd.c (finish_command): Use filtered printfs.
2407 * cplus-dem.c: Add struct tags to a few unnamed structs.
2408 * valops.c (value_coerce_array): Improve comments.
2409 * valprint.c (type_print_varspec_suffix): Print array size only
2410 if greater than zero.
2411 * m88k-tdep.c: Shift some lines left by one space, that had
2412 apparently been trashed at some point.
2413 * TODO: More things to do, a few got done.
2415 Thu Jul 18 22:46:05 1991 John Gilmore (gnu at cygint.cygnus.com)
2417 * symtab.h (LOC_EXTERNAL): Eliminate in favor of LOC_STATIC.
2418 (ldsymoff, ldsymlen, globals_offset, statics_offset): Improve
2420 * dbxread.c (read_dbx_symtab): LOC_EXTERNAL -> LOC_STATIC.
2421 * expread.y, findvar.c, symmisc.c: Ditto.
2422 * printcmd.c (address_info): Update printed forms of LOC_
2423 symbols. Elim LOC_EXTERNAL.
2424 (print_frame_args): Keep track of param stack offsets before
2425 re-looking up to find the local register param is kept in.
2427 * mipsread.c: Use <symconst.h> and <sym.h> rather than <syms.h>.
2428 Further integration of mipsread into gdb. Eliminate unused
2429 routines, duplicate declarations. Handle static symbols in
2430 psymtabs as well as external symbols. When reading symtabs,
2431 insert symbols into the correct block (global, static, or a local
2433 (read_mips_symtab, parse_partial_symbols): Don't pass useless
2435 (mipscoff_symfile_read): Don't call select_source_symtab.
2436 (parse_symbol): Use SYMBOL_VALUE_ADDRESS where appropriate,
2437 rather than SYMBOL_VALUE.
2438 (parse_external): Comment clobbering of top_stack.
2439 (parse_partial_symbols): Update comments. Allocate and parse
2440 static symbols as well as external symbols. FIXME, enum values
2441 are not handled in this pass, but should be. Inline new_psymbol.
2442 Use SYMBOL_VALUE_ADDRESS.
2443 (psymtab_to_symtab_1): Read symbols into global static block
2444 by default (until enter some function's local block context).
2445 (sort_blocks): Clean up STATIC_BLOCK as well as GLOBAL_BLOCK.
2446 (destroy_all_symtabs, new_psymbol): Eliminate, unused.
2448 * source.c (select_source_symtab): Select a source symtab
2449 from either the symtabs or, failing that, the psymtabs.
2450 (list_command): Update error message.
2451 (forward_search_command, reverse_search_command): Use getc, not
2452 fgetc, for speed. FIXME, add comment about buffers that die if
2453 overrun by long line.
2455 * values.c (unpack_field_as_long, modify_field): Avoid shifting
2456 by an entire word, which is not portable, if we have a 32-bit
2457 field. (Code in dbxread.c already turns such bitfields, if
2458 aligned, into ordinary ints, but fixing this will help for other
2459 symbol formats and for future changes.)
2460 * core.c (core_open): Handle ANSI const brain death.
2461 * utils.c (vprintf): Fix varargs typo.
2463 Sun Jul 14 00:42:53 1991 John Gilmore (gnu at cygint.cygnus.com)
2465 * findvar.c (find_var_value): Handle &function better.
2466 * TODO: Document work needed on &fn and &array.
2467 * printcmd.c (print_address_symbolic): New arg is the prefix
2468 to print if a name is printed.
2469 (print_address_demangle): Honor "set print address" now.
2470 Use new arg above to improve spacing of output.
2471 * valprint.c (val_print): When printing function pointers,
2472 print symbolic form too.
2473 * breakpoint.c (breakpoint_1): Use new print_address_symbolic.
2475 Mon Jul 8 19:02:46 1991 John Gilmore (gnu at cygint.cygnus.com)
2477 * core.c (memory_error): Reword error msg to mislead less.
2479 * mips-pinsn.c (print_insn_arg 'd'): Print $ with reg name.
2481 * mipsread.c (read_mips_symtab, read_the_mips_symtab,
2482 parse_partial_symbols): Use newer BFD internals (external_filehdr
2483 and external_aouthdr), byte-swap the fields that we care about
2484 before using them, and make the file header data local to
2485 read_the_mips_symtab rather than global.
2487 Sat Jul 6 01:34:15 1991 John Gilmore (gnu at cygint.cygnus.com)
2489 * ns32k-opcode.h (movmw, movmd): Fix opcodes. Bug fix
2490 from Rune Nerg}rd <runene@ifi.uio.no> on 5 Jul 1991.
2492 * main.c (command_line_input): Flush stdout and stderr
2493 before every call to readline. This reportedly fixes a bug
2494 that comes up in Sys V running emacs-gdb and/or xxgdb,
2495 when stdin/out are pipes or sockets.
2497 Thu Jul 4 14:47:06 1991 John Gilmore (gnu at cygint.cygnus.com)
2499 * configure.in, Makefile.in: Avoid rebuilding "depend" as much.
2500 Avoid declaring Makefile dependencies, because GNU Make stupidly
2501 tries to update it if we do.
2503 * coffread.c: Revise for minor changes to bfd internal coff
2506 * configure: If -template= is given a relative path, make it
2507 absolute before recurring in subdirectories.
2509 * configure, configure.in, Makefile.in: Install "configure" script
2510 as replacement for config.gdb.
2511 * config.gdb, Makefile.dist, Makefile.sdir: Remove
2512 * README: Update for configure, mostly. FIXME.
2514 * Add dec3100 as equivalent to littlemips. Indicate in all host &
2515 target config files that they are for the host. When the lines
2516 get copied into the Makefile, this makes it more obvious what's
2519 Mon Jun 24 23:49:07 1991 John Gilmore (gnu at cygint.cygnus.com)
2521 * sparc-opcode.h (trap opcodes): Avoid leading spaces or
2522 tabs, which end up in the disassembler output inadvertently.
2524 Wed May 29 23:01:03 1991 John Gilmore (gnu at cygint.cygnus.com)
2526 Make it compile cleanly in an ANSI GCC2 environment.
2528 * blockframe.c: <stdio.h>
2529 * cplus-dem.c: free takes a void *, ifdef __STDC__
2530 * dbxread.c (read_huge_number): avoid gcc2 bug hoisting calc of
2532 * defs.h (alloca): Avoid doing anything if alloca already def'd.
2533 * stddef.h, stdlib.h: Remove these files.
2534 * symtab.c: Avoid declaring qsort, close.
2535 * symfile.c: Avoid declaring close.
2536 * utils.c (vprintf): Declare "ap" arg as proper va_alist.
2537 * sparc-tdep.c: Avoid including lots of Sun-host-specific files.
2539 Assorted other changes.
2540 * dbxread.c: include "libaout.h", not "liba.out.h".
2541 * printcmd.c (print_frame_args): Set recurse properly for
2542 indentation of struct and array parameters.
2543 * valops.c (value_cast): Allow cast to void.
2544 * infrun.c (resume): If NO_SINGLE_STEP, call machine dependent
2545 single_step() in a target-independent fashion.
2546 * sparc-tdep.c (single_step): Don't call ptrace ourselves, just
2547 set up to be ready to continue. This makes us target independent.
2548 * infptrace.c (child_resume): Remove call to single_step; now
2549 can single step a SPARC target of any kind.
2551 Wed May 22 18:18:24 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
2553 * Makefile.dist, doc/gdb.texinfo, doc/*-m4.texinfo: split up GDB
2554 docn into separate sections---basically chapters, plus two loose
2555 pieces that can be configured to go in different places. This
2556 allows GNU m4 to preprocess the manual without coredumping.
2558 * Makefile.dist: tell TeX where to find texinfo.
2560 Mon May 20 12:15:04 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
2562 * Makefile.dist, doc/gdb.texinfo: respectively create, and use,
2563 the new target "rdl-apps.texinfo" which captures the Makefile
2564 variable that records where to find the Readline libraries.
2566 Sun May 19 05:36:59 1991 John Gilmore (gnu at cygint.cygnus.com)
2568 * tahoe-pinsn.c: #include "tahoe-opcode.h", not "opcode.h".
2569 * tm-tahoe.h (FIX_CALL_DUMMY): Ignore more parameters.
2570 * defs.h (const, volatile): Only define if not already defined.
2571 * Makefile.dist (gdb.tar.Z): Create doc subdir w/out CVS/RCS crud.
2573 * README: Update for release 3.95.
2574 * config.gdb: Don't create readline dir in subdir builds.
2575 * main.c: Include with "..." form for non-system include files,
2576 so "gcc -MM" for "make depend" works.
2577 Include readline files with "...h" rather than <readline/...h>.
2578 * mipsread.c: Include "ecoff.h" rather than "intel-coff.h".
2580 * coffread.c: Undo minor damage done by Rich Pixley. Use
2581 different internal and external representations of COFF
2582 data structures. Use new BFD routines for swapping them in and
2584 * symfile.c (free_named_symtabs): Avoid freeing file names that
2585 are null or empty. Old i960 tools seem to produce files that
2586 claim to have empty names, causing each successive file read
2587 to blow away the previous one.
2588 * sparc-xdep.c (deferred_stores): Repair minor damage by Rich.
2589 Move deferred_stores to top of file, but don't separate its
2590 #define's from its variable. Add commentary.
2591 * Makefile.dist: Fix Rich damage; undo "configure" changes in
2592 favor of keeping the (working) config.gdb. Move readline
2595 Fri May 17 12:49:56 1991 Per Bothner (via gnu at cygint.cygnus.com)
2597 * dbxread.c (read_struct_type): Try to handle g++ version 1 MI
2599 * infptrace.c (fetch_registers): no result, since now void.
2600 * tconfig/news: target depends on m68k-tdep too.
2602 Fri May 17 14:40:14 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
2604 * Makefile.dist: added readline/inc-*.texinfo to dependencies for
2607 * readline/inc-history.texinfo, readline/inc-readline.texinfo:
2608 applied various small fixes due to or inspired by RMS comments
2610 * doc/gdb.texinfo: finished using all RMS comments, save those for
2611 appendices on readline and cmd history (which are in other source
2614 Thu May 16 18:06:05 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
2616 * doc/gdb.texinfo: (1) Updated w/ref to RMS comments through
2617 chapter 9; (2) documented 'break' command's menu mode for
2618 overloaded names, in response to hgs problem report C++ p-31
2620 Wed May 15 11:02:48 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
2622 * doc/gdb.texinfo: (1) better introductory example; (2) more
2623 consistent use of @code, @samp, @file, @kbd throughout; small
2624 cleanups to first three nodes; (3) new "Contributors" node;
2625 (4) Appendix, Renamed Commands; (5) divert specialized startup
2626 instructions to "Targets" chapter for generic manuals, while
2627 leaving them up front for manuals specific to specialized
2628 environments; (6) apply fixes from RMS comments through chapter 4.
2630 * pretex.m4: modify explanatory text slightly (and redefine
2631 "regexp") to keep GNU m4 from complaining. (It still crashes
2632 later, but one step at a time...)
2634 Wed May 15 10:32:12 1991 John Gilmore (gnu at cygint.cygnus.com)
2636 * readline/readline.c (update_line): Avoid dereferencing a pointer
2637 before comparing it to its bounds. Saber caught this.
2638 (init_terminal_io): Don't set BC from the "pc=" termcap variable,
2639 and only set PC if tgetstr returned non-null. Saber caught this.
2641 Tue May 14 16:29:53 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)
2643 * Makefile.dist: put gdb.dvi stuff (updated to use M4 preprocessor
2644 stuff for config manual) here where it counts; updated
2645 to use new subdir structure (gdb/doc/).
2647 * Makefile: generated from above via
2651 * gdbint.texinfo: added instructions on generating gdb.info* files
2652 locally for release. These are ordinary info
2653 files, formatted from gdb.texinfo (via gdb-all.texinfo, see
2654 Makefile)---but due to use of texinfo 2, can't count on makeinfo
2655 to generate these, so we distribute them already formatted.
2657 * gdb.texinfo: included full Info node and menu crud (as generated
2658 by C-u M-x texinfo-master-menu using the texinfo-2 elisp code).
2660 * Makefile: updated "gdb.dvi" target to use M4 preprocessor;
2661 put in comments-for-future gdb.info target (one day makeinfo will
2664 Tue May 14 13:51:36 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)
2666 * gdb.texinfo: Updated to include new or old undocumented
2667 commands, at least the following (perhaps some others I forgot to
2668 record): info f, info float, info path, info program, info s, info
2669 set, info source, info terminal, info types, info user, set/show
2671 Also covered all recent GDB command renames for v4.
2673 Mon May 13 14:57:46 1991 John Gilmore (gnu at cygint.cygnus.com)
2675 * mipsread.c: Rather than keeping count of how many symtabs
2676 and psymtabs we have, for sorting purposes, count them when
2677 we need to sort. This fixes bug in rereading of symbol tables.
2679 Fri May 10 15:43:33 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)
2681 * infcmd.c: renamed "info path" to "show paths"

2692 Fix up "saber_gdb" to work again.
2693 * saber.suppress: Update.
2695 * coffread.c, exec.c, infptrace.c, inftarg.c, remote.c, solib.c,
2696 symtab.h, target.c, target.h: Lint.
2697 * core.c: setup and select frame after reading shared libs,
2698 else reading shared libs will clobber them. Lint.
2699 * utils.c (error): Force out any buffered wrap text.
2701 Fri May 3 22:01:56 1991 John Gilmore (gnu at cygint.cygnus.com)
2703 * remote.c: Remove decls of memory_insert_breakpoint
2704 and memory_remove_breakpoint, no longer used. (Suggestion of
2707 * Makefile.dist: use ${subdir} in paths of BFD and LIBIBERTY,
2708 to make it easier to interface to "configure"'d libraries.
2710 Fri May 3 13:10:01 PDT 1991 Roland Pesch (pesch at fowanton.cygnus.com)
2712 * valprint.c: introduce "set p", "set pr", "show p" and "show pr" as
2713 aliases for set/show print.
2715 Thu May 2 11:22:02 1991 Jim Kingdon (kingdon at cygint.cygnus.com)

2765 dc_dcontext_t not int.
2767 * coffread.c [TDESC]: Use system include files not <intel-coff.h>.
2769 * coffread.c [TDESC]: Move setting of debug_info from
2770 coff_symfile_read to find_linenos and make it work with BFD.
2772 * cplus-dem.c [__STDC__]: Make x{m,re}alloc return void*.
2774 * signame.c: Cast const char* to char* when assigning to sys_siglist.
2776 * utils.c (strsave): Make arg const char* not char*.
2778 * infrun.c (wait_for_inferior) [SHIFT_INSN_REGS]: Use

2799 Mips bringup and general cleanup
2801 * cplus-dem.c: Move CPLUS_MARKER define to after defs.h.
2802 * infptrace.c (PT_WRITE_D, PT_READ_D): Use correct values.
2803 (This still doesn't seem to make MIPS bkpts work.)
2804 * mipsread.c: Remove dup "Reading symbol data..." msg.
2805 (symbol_file_command, add_file_command): Remove, obsol.
2806 * printcmd.c (ptype_command): Say "an enum" rather than "a enum".
2807 Wrap output appropriately.
2808 * stack.c (locals_info, catch_info, args_info): Check
2809 selected_frame rather than target_has_stack or coredumping.
2810 * valprint.c (type_print_varspec_suffix): Wrap "ptype" output of
2811 enums appropriately.
2813 Wed May 1 14:10:22 1991 Jim Kingdon (kingdon at cygint.cygnus.com)
2815 * signame.c: Include defs.h and param.h.
2817 * cplus-dem.c: Include defs.h and param.h.
2818 Makefile.dist: Don't hack in the "param.h".
2819 param.h: Don't include defs.h.
2821 * expread.y: Use a union to deal with the fact that type_stack
2822 can have both ints and enum type_pieces in it.
2823 ({push,pop}_type_int): New functions.
2825 Tue Apr 30 13:18:58 1991 Jim Kingdon (kingdon at cygint.cygnus.com)

2837 symtab.c, cplus-dem.c, value.h, expread.y, valprint.c,
2838 copying.awk, solib.c, inflow.c, symmisc.c
2839 : Lint. Use read_memory not read_memory_integer on CORE_ADDR's.
2840 Use {value_as,unpack}_pointer (added to values.c)
2841 not {value_as,unpack}_long on CORE_ADDR's.
2842 Use longest_to_int (added to defs.h) instead of cast to int.
2843 Remove from_tty arg to mod_path.
2844 Put symfile_bfd in {coff,dbx}read.c not symfile.h.
2845 Use OP_NULL instead of 0 where dummy enum exp_opcode needed.

2883 * xm-tahoe.h: Remove USE_OLD_TTY (not needed now that terminal.h
2884 includes sgtty.h before sys/ioctl.h).
2886 Sun Apr 28 22:04:47 1991 Jim Kingdon (kingdon at cygint.cygnus.com)
2888 * param-no-tm.h: Make BITS_BIG_ENDIAN defined to 0/1, not defined
2889 or not defined. Don't define it based on TARGET_BYTE_ORDER if

2891 mips-opcode.h (BIT_FIELDS_*),
2892 values.c (modify_field, unpack_field_as_long):
2893 Use #if BITS_BIG_ENDIAN not #ifdef BITS_BIG_ENDIAN.

3318 (set_section_command): New command ("section xxx yyy" -- should
3319 be renamed to "set section xxx yyy" FIXME) which sets the
3320 base address of a section of the exec file, overriding the

3333 * i386-pinsn.c: Move #includes to top, remove useless ones.
3334 * i386-tdep.c: Don't bother including <.../reg.h> since we

3351 current frame in the core file, if we have one.

3358 * infptrace.c: Avoid <sys/ptrace.h> on USG.
3360 * Make all file names fit in 14 characters (sigh and damn!):
3361 mv hp300hpux-xdep.c hp300ux-xdep.c
3362 mv symmetry-xdep.c symm-xdep.c
3363 mv symmetry-tdep.c symm-tdep.c

3369 mv remote-sa.m68k.shar rem-m68k.shar
3370 mv remote-multi.shar rem-multi.shar
3371 * Makefile.dist, README, config.gdb, convex-pinsn.c,
3372 tconfig/symmetry, tconfig/vxworks960, tconfig/vxworks68,
3373 xconfig/hp300hpux, xconfig/symmetry: Change names to shorter
3376 * command.c (user_info_1, user_info): New command for listing
3377 the user-defined commands.
3379 Wed Apr 3 15:00:26 1991 John Gilmore (gnu at cygint.cygnus.com)
3381 * dbxread.c (really_free_pendings): Clear file_symbols
3382 and global_symbols after freeing them; otherwise, running
3383 this function twice (if it appears twice on the cleanup
3384 chain), we try to free things twice.
3386 * dbxread.c (read_dbx_symtab): Calculate end_of_text_addr
3387 based on text_addr (the address of text in core), not on addr (the
3388 offset between text in the .o file and in core). This change
3389 is from Peter Schauer.
3391 * main.c: Define ALL_CLEANUPS as a cast of zero.
3392 (return_to_top_level): Use it.
3393 (main): Do all cleanups after each command run as part
3394 of the gdb startup sequence. Also do all cleanups before
3395 entering the command loop, and every time we exit the command
3396 loop and reenter. Before, the cleanups from the startup sequence
3397 were being left undone until the first error!
3398 (command_loop): Rename do_nothing cleanup to command_loop_marker
3399 so we can see it easily when examining the cleanup chain.
3400 (init_signals): Add another do_nothing for signal handling.
3401 (quit_command): Only try to kill target if it has execution.
3402 Problems in the target stack got us into a state where
3403 inferior_pid was nonzero but none of the targets had execution.
3404 In this state you couldn't exit gdb.
3406 * dbxread.c: Two changes from Peter Schauer.
3407 (echo_command): Fflush output after an echo command.
3408 (show_history): Pass all args to cmd_show_list.
3410 * utils.c (init_malloc): Call mtrace to turn on tracing
3411 if the environment variable MALLOC_TRACE is set to a file name.
3412 * mtrace.c: Add source file which provides a log of every malloc,
3413 free, and realloc to a trace file.
3414 * mtrace.awk: Add source file which analyzes the trace file.
3415 * Makefile.dist (GNU_MALLOC, MALLOCSRC): Add mtrace.{c,o,awk}.
3416 (VERSION): Roll to 3.94.3.
3418 * breakpoint.c (breakpoint_1): Add a space to "i watch" output.
3419 (check_duplicates): Don't bother with watchpoints.
3420 (set_raw_breakpoint): Comment about danger of this routine.
3421 (watch_command): Parse and eval all args before calling
3424 * solib.c (find_solib): Avoid error in referencing memory to
3425 see if any more shared libraries have been added. This is
3426 particularly useful if the target has terminated. Bug reported
3429 Changes from Peter Schauer <pesrem@regent.e-technik.tu-muenchen.de>
3430 in bringing up 3.94.2 on the Sun-3.
3432 * Makefile.dist: Include CFLAGS in rule for cplus-dem.o.
3433 * breakpoint.c (enable_breakpoint): Check for valid watchpoint
3434 expression (in scope) before reenabling watchpoint.
3435 * signame.c (init_sigs): Add missing declaration of i, fix
3436 sys_siglist declaration.
3437 * source.c (list_command): Fixed range computation to use
3439 * stack.c (backtrace_command): Do not allow command if target has
3440 no stack, print informative error message.
3441 * target.c (target_command): Do not write into command line
3442 because this fails if the target command is used in a user defined
3443 command. [This change was enhanced by gnu to support any-
3444 unique-prefix matching on target names.]
3445 * valops.c (value_struct_elt): Avoid infinite loop on an
3446 erroneous attempt to print the member of function (try p main.p).
3448 Mon Apr 1 17:05:45 1991 John Gilmore (gnu at cygint.cygnus.com)
3450 * expread.y (name_no_typename): Avoid reduce/reduce errors
3451 caused by ambiguity in handling NAME_OR_INT and NAME_OR_UINT.
3452 Since the GDB parser really doesn't use name_no_typename in a
3453 name-only context, the parser can't tell the diff between
3454 names and numbers here. Avoid allowing a name_no_typename
3455 to be a NAME_OR_*INT to resolve the conflict.
3457 Sun Mar 31 20:12:07 1991 John Gilmore (gnu at cygint.cygnus.com)
3459 Bugfixes from Mark Fox (markf@wrs.com) (test=testField.c):
3461 * valprint.c (val_print_fields): bitfield printing didn't handle
3462 byte order. Indirect through a few more fns to cope.
3464 * values.c (modify_field): also cope with byte order.
3466 Sat Mar 23 10:02:21 1991 John Gilmore (gnu at cygint.cygnus.com)
3468 Cleanup for release 3.94.2:
3470 * Makefile.dist: Pull REMOTE_OBS. Fix saber includes for BFD
3471 include files. Roll version to 3.94.2.
3473 * coffread.c (init_stringtab): Read length into unsigned char
3474 array before swapping; don't assume 32-bit longs.
3476 * target.c (target_info): Don't bother with get_sym_file, just use
3477 the symfile global variable.
3478 * symtab.h, symfile.c (get_sym_file): Delete it.
3480 * dbxread.c (dbx_symfile_init): Don't depend on long == 4 bytes.
3481 (define_symbol): Set symbol line number to 0 if not gcc-compiled.
3482 (read_type): Replace one more error() with complain().
3484 * mipsread.c (parse_partial_symbols): Replace printf with complain.
3486 * i960-tdep.c: Fix copyright attribution.
3488 * config.gdb: Quote all backquotes in doublequotes. You can
3489 quote me on that. BSD 4.4 shell found this one.
3491 * infptrace.c (throughout): The third argument to ptrace is an
3494 * infrun.c (wait_for_inferior): When program has terminated, we
3495 have to call target_terminal_ours before we pop that target off
3496 the stack (e.g. before a call to target_kill or
3497 target_mourn_inferior). This fixes problem where a program
3498 terminates, then GDB stops for (tty output) and you have to type
3499 "fg" to the shell to resume it. FIXME: This code for what to
3500 do after termination really should be in normal_stop instead.
3502 * gdbcore.h (read_memory_check): Change declaration; it changed
3505 * terminal.h: Include <sgtty.h> before <sys/ioctl.h>, since in BSD
3506 4.4 prereleases, this avoids a bug in their sgtty compatability
3508 * remote.c: Use terminal.h rather than hand-rolling the same.
3510 * signame.c, signame.h (psignal): Arg is unsigned, not int.
3511 * utils.c (strsave, strstr): Fix arg types.
3512 * valprint.c (val_print): lint
3514 MIPS symbol table support from Per Bothner:
3516 * symfile.c (symtab_fns): Remove initializer table that needs to
3517 be hacked for each new symbol file format supported.
3518 (add_symtab_fns): New function, chains symbol table
3519 handlers into the global list.
3520 (symfile_init): Search this list.
3521 * symfile.h: Add next pointer, declare add_symtab_fns.
3522 * coffread.c (_initialize_coffread): Call add_symtab_fns.
3523 * dbxread.c (_initialize_dbxread): Call add_symtab_fns.
3525 * mipsread.c (psymtab_to_symtab_1): return void instead of (struct
3526 symbol *). Thus, we no longer need the hack to trash
3527 pst->filename. Good, since that hack confused code in symfile.c!
3529 (reorder_symtabs, destroy_all_symtabs): Removed static
3530 all_symtabs, which was used to qsort symtabs in reorder_symtabs.
3531 Instead, the latter now uses a temporary array (stack-allocated
3532 from an obstack, and then freed).
3534 (parse_symbol): Added a hack to fix up BLOCK_{START,END} if they
3535 haven't been set in the outermost stBlock of a procedure. This was
3536 a problem with f77 binaries on Ultrix 4.?.
3538 (new_symtab, new_symbol, new_type): Continue changing code to use
3539 obstacks more and otherwise conform to dbxread internal style.
3540 Made the free_code of symtabs be free_linetable (as in dbxread)
3541 instead of free_contents. This implies memory leaks when reading
3542 a new symbol table, until the conversion is finished. Did change
3543 (struct symbol) and (struct type) to be allocated on the
3544 symbol_obstack. Blocks and blockvectors are among the things
3547 * mipsread.c (parse_partial_symbols, parse_fdr): It hasn't been
3548 tested much, but it solved one problem (reported by Meissner), and
3549 cleans up some other things. The problem happened when an
3550 included file contains actual code (functions) and not just
3551 definitions. The mips coff is a little inconvenient there, since
3552 it may cause a procedure to be mapped to the wrong psymtab.
3554 * mips-tdep.c (heuristic_proc_desc): Minor cleanup.
3555 * mips-xdep.c (fetch_core_registers): Minor cleanup. FIXME,
3556 this will need work for the new core paradigm.
3558 Opcode patches from the net:
3560 * mips-opcode.h: fix incorrect disassembly of the mfc1, cfc1, and
3561 ctc1 instructions. Also, the cvt.d.w and cvt.s.w instructions were
3562 missing altogether - they are added here. From Bruce Bauman.
3563 * mips-opcode.h: The low mask for C0 instructions was too small.
3564 From Garrett Lau. I modified the fix to check the entire 32-bit
3567 * ns32k-opcode.h: Fix opcodes for deiw and deid. From Bruce
3570 Thu Mar 21 12:56:46 1991 John Gilmore (gnu at cygint.cygnus.com)
3572 Roll in changes from Per Bothner (Tue, 25 Sep 90 11:11:04):
3574 * dbxread.c (read_type): Pointer subtraction (value_sub in
3575 valarith.c) sometimes failed because the types of the
3576 pointers being subtracted were not identical.
3577 These differed because dbxread.c was allocating pointer types
3578 using dbx_alloc_type+smash_to_pointer_type instead of
3579 lookup_pointer_type. I failed to find a justification for the
3580 former, so I changed it to use the latter. Similarly, I
3581 replaced smash_to_function_type by lookup_function_type,
3582 and smash_to_reference_type by lookup_reference_type.
3584 * mipsread.c (parse_symbol, upgrade_type, parse_procedure,
3585 _initialize_mipsread): corresponding changes.
3587 * symtab.c (smash_to_{pointer,reference,function}_type): eliminate.
3589 * source.c (mod_path): Do tilde_expand on each component of the path,
3590 rather than on the (list of) paths as a whole.
3591 (print_source_lines): Set first_line_listed in addition to
3592 current_source_symtab and current_source_line. If the source was
3593 not findable, after a "dir" command to fix the problem,
3594 a "list" would get the wrong lines.
3596 While I was there... (gnu):
3598 * dbxread.c (read_type): Change error to complaint.
3600 Thu Mar 21 12:56:46 1991 John Gilmore (gnu at cygint.cygnus.com)
3602 First attempt at detailed understanding of symbol table memory alloc.
3604 * dbxread.c (dbx_symfile_read): Free our string table if we
3605 aren't the mainline. Free the "info" struct since we're done with
3607 (init_psymbol_list): Free any previously allocated psymbol lists.
3608 (): FIXME: Should realloc-down the psymbol lists when done reading
3609 the main symbol file?
3611 * symmisc.c (free_symtab): Free fullname field too.
3613 * xm-hp300hpux.h (USG): #undef then #define so Makefile can -D.
3614 (REGISTER_ADDR): Make result type unsigned int.
3616 * xconfig/{i386*,hp300hpux,altosgas,altos}: All config files that
3617 define REGEX must also define REGEX1 (its dependency).
3619 Tue Mar 19 21:28:57 1991 John Gilmore (gnu at cygint.cygnus.com)
3621 * tconfig/i960: No longer works, points you at vxworks960 or
3624 * xgdb.c, XGDB-README: Remove file. Users can get the much
3626 * Makefile.dist: Remove all trace of xgdb.
3628 * breakpoint.c (breakpoint_1): Pass demangle arg to
3629 print_address_symbolic.
3630 (clear_breakpoints): Remove unused function.
3631 (breakpoint_re_set_one): Guts of breakpoint_re_set.
3632 (breakpoint_re_set): Use catch_errors to do them all anyway.
3634 * gdb-int.texinfo (Host versus Target): Add section on what is
3635 a "host" feature versus what is a "target" feature.
3637 * infcmd.c (path_command, path_info): Handle the PATH variable
3638 (object search path) as conveniently as the source search path.
3639 * environ.c (set_in_environ): Set some vars in GDB's environment,
3640 in addition to the child's. PATH, G960BASE, G960BIN for starters.
3641 * source.c (mod_path): New function, from guts of
3642 directory_command, modifies a path. Used by path_command.
3643 (directory_command): Call it.
3644 * defs.h (strsave): Declare.
3646 * utils.c (sevenbit_strings): Add new printing option.
3647 (printchar): Use it.
3648 (strsave): Provide this handy helper routine.
3649 (set_width_command): Rename set_screen_width_command.
3650 (_initialize_utils): "set screen-width" => "set width";
3651 "set screen-height" => "set height"; add sevenbit-strings.
3653 * infcmd.c (do_registers_info): Print floating point registers
3654 in raw hex as well as float format, regardless of whether it is
3655 a "virtual" convertible register.
3656 * tm-sparc.h (PRINT_REGISTER_HOOK): Print every pair of float
3657 regs as a double, just in case it's being used that way.
3658 * values.c (unpack_long): Comment on array/function coercion.
3659 (unpack_double): Argument is in target byte order now. For
3660 integer arguments, just call unpack_long and float the result.
3661 * m68k-tdep.c: include defs.h for "const" handling.
3662 * remote-nindy.c: Use ieee-float stuff.
3663 (nindy_fetch_registers): Unpack double regs to host double, then
3665 (nindy_store_registers): Pack extendeds to host double, flip
3666 around by misusing unpack_double, send as target double.
3668 * tm-vxworks68.h (FRAME_CHAIN): Handle current frame pointer of
3669 zero, as when stopped at the first instruction of a process.
3671 * blockframe.c: Fix filename in comment (param.h => tm.h).
3672 * sparc-tdep.c (skip_prologue): More explicit nudging comments.
3673 * tm-68k.h: Fix typos.
3675 Fri Mar 15 01:09:34 1991 John Gilmore (gnu at cygint.cygnus.com)
3677 Changes from a bringup on the DEC Vax under Ultrix 4.0.
3679 * coredep.c (fetch_core_registers): Pass end-address of register
3680 section to register_addr as expected. Don't call supply_register
3681 if we'd just pass it garbage.
3683 * dbxread.c (read_dbx_symtab): Skip N_NSYMS on Ultrix.
3685 * exec.c (xfer_memory): Use boolean xfer_fn result, not int.
3687 * target.c (push_target, target_info): Cast enums to int for < or
3690 * stack.c (print_frame_info): Identify source file & line
3691 even if we can't print it.
3693 * xm-vax.h (MISSING_VPRINTF): No longer missing in Ultrix V4.0.
3695 Sat Mar 9 10:08:20 1991 John Gilmore (gnu at cygint.cygnus.com)
3697 Clean up IEEE floating point support.
3699 * ieee-float.h: New file.
3700 * ieee-float.c: Write real routines to convert between host
3701 doubles and various target IEEE extendeds.
3702 * m68k-xdep.c: Eliminate assembler code for extended floats.
3703 * xconfig/{3b1,altos,altosgas,hp300bsd,isi,news,news1000,sun2os3,
3704 sun2os4,sun3,sun3os3,sun3os4}: Eliminate use of m68k-xdep.o.
3705 * tm-i960.h, tm-68k.h (REGISTER_CONVERT_TO_VIRTUAL,
3706 REGISTER_CONVERT_TO_RAW): Use ieee_extended_to_double and
3707 double_to_ieee_extended.
3708 * i960-tdep.c: Define ext_format_i960.
3709 * m68k-tdep.c: Define ext_format_68881.
3710 * sparc-tdep.c: Define ext_format_sparc, though unused.
3711 * Makefile.dist (HFILES): Add ieee-float.h.
3712 * inftarg.c: #include "ieee-float.h" for the REGISTER_CONVERT
3715 Obsolete the "coffstrip" program in favor of using BFD's strip.
3717 * nindy-share/coffstrip.c: Remove file.
3718 * nindy-share/nindy.c (coffstrip): Routine to run bfd_strip.
3719 * Makefile.dist: Remove references to nindy-share/coffstrip.c.
3720 * tconfig/nindy960: Remove reference to coffstrip.o.
3722 * Makefile.dist: Roll version number to 3.94.1 (not yet final).
3724 Wed Mar 6 09:56:45 1991 John Gilmore (gnu at cygint.cygnus.com)
3726 * symfile.h: Add symfile_bfd, common between dbxread and coffread.
3727 * dbxread.c: Remove static symfile_bfd.
3728 * infcmd.c (do_registers_info): Add PRINT_REGISTER_HOOK, though
3730 * inftarg.c (child_detach): Pop the child_ops vector if the
3731 detach is successful.
3732 * remote-nindy.c (nindy_create_inferior): Don't push a new
3733 nindy_ops since nindy uses the same one for execution and memory
3735 * core.c (core_ops): Use child_attach and child_create_inferior
3736 rather than default attach and create_inferior functions.
3738 Handle floating point registers in core files.
3740 * sparc-xdep.c (fetch_core_registers): Rewrite for float support.
3741 * sun3-xdep.c (fetch_core_registers): Rewrite for float support.
3742 This version untested since BFD doesn't yet support sun3 core
3744 * hp300hpux-xdep.c: Rewrite fetch_core_registers to new calling
3745 conventions. Fix comments and style. This version has not
3746 been compiled yet, since we have no HP inhouse.
3747 * core.c (get_core_registers): Look for two sections, ".reg"
3748 and ".reg2", and pass both to fetch_core_registers sequentially.
3750 Revise directory path yet again.
3752 * source.c (forget_cached_source_info): Not static any more.
3753 (init_source_path): New default source path is "$cdir:$cwd".
3754 (dir_command): Handle variable arguments ($cdir, $cwd).
3755 (source_info): Print "Compilation directory" rather than
3756 "Originally compiled in" to remind people of $cdir.
3757 (openp): If the path contains $cwd, use current directory.
3758 (open_source_file): If compilation directory is known, replace
3759 first $cdir in path with the compilation directory.
3760 (print_source_lines): Even if we can't print the lines, set the
3761 current symtab and line for future commands like "info source" or
3762 "breakpoint". Also, error message now contains the file name,
3763 line number, and file access error message.
3764 (_initialize_source): Fix help text to describe changes.
3765 * main.c (cd_command): Forget cached source info when we chdir.
3766 * utils.c (strstr): Add simple implementation.
3768 Tue Mar 5 01:41:40 1991 John Gilmore (gnu at fowanton.cygnus.com)
3770 * coffread.c (read_one_sym, init_linetable, init_stringtab):
3771 Byte-swap COFF symbol tables if necessary when reading them in.
3772 Use complain() to replace error message in one spot. Needs
3773 corresponding change in bfd/coff-code.h to make some symbol
3774 swapping routines non-static.
3776 Mon Mar 4 00:53:40 1991 John Gilmore (gnu at cygint.cygnus.com)
3778 Merge changes from Eirik Fuller, for UTek.
3780 * defs.h (errno): Add declaration.
3781 * altos-xdep.c, arm-xdep.c, convex-xdep.c, gould-xdep.c,
3782 hp300hpux-xdep.c, infrun.c, inflow.c, infptrace.c, i386-tdep.c,
3783 i386-xdep.c, pyr-xdep.c, mips-xdep.c, remote-eb.c, remote-nindy.c,
3784 remote-vx.c, source.c, standalone.c, stuff.c, sun386-xdep.c,
3785 symmetry-tdep.c, symmetry-xdep.c, umax-xdep.c, utils.c: Eliminate
3786 declarations of errno.
3788 * remote-eb.c: Define B19200 and B38400 as EXTA and EXTB.
3790 * remote-vx.c: Include <sys/time.h> for UTek; Sun gets it via
3791 <rpc/rpc.h> and <rpc/types.h>.
3793 Sat Mar 2 15:47:55 1991 John Gilmore (gnu at cygint.cygnus.com)
3795 * i960-tdep.c (examine_prologue): Add new argument limit,
3796 which stops the scan at the end of the prologue, or at the PC.
3797 This fixes a problem where it walks down into the code for the
3798 user's statements if that code looks like function prologues.
3799 Mark Fox and I have been bouncing this code back and forth, making
3800 small changes to it. Callers changed to match.
3802 Tue Feb 26 01:47:07 1991 Cygnus John Gilmore (cygnus at yuba)
3804 Cleanup for gdb-3.94 release final:
3806 * Makefile.dist: Remove remote-vx.c, remote-nindy.c, and all
3807 the .c files from vx-share and nindy-share, from the various
3808 macros, since they are not found via ALLDEPFILES.
3809 (SFILES): Add tm-i960.h.
3810 (alldeps.mak rule): Break out ALLDEPFILES_MAINDIR and
3811 ALLDEPFILES_SUBDIR. List all the nindy and vxworks subdir files
3813 (TAGFILES_MAINDIR): Change ALLDEPFILES to ALLDEPFILES_MAINDIR.
3814 (gdb.tar.Z): Use ALLDEPFILES_SUBDIR as well as SFILES_SUBDIR.
3816 Mon Feb 25 16:02:35 1991 Cygnus John Gilmore (cygnus at oldman)
3818 * am29k-tdep.c: Add contribution line.
3819 (examine_prologue): Cache information about function prologues in
3820 the misc-function-vector to avoid lots of references over the
3821 serial line while examining instructions.
3823 * core.c (core_close): New function made from cleanup_core.
3825 * core.c, exec.c, inftarg.c, remote-eb.c, remote-nindy.c,
3826 remote-vx.c, remote.c, target.c, target.h,
3827 Update target_ops vector to add attach, close, and load entries.
3828 Use add_syms_addr_command, not add_file_addr_command, for
3829 add_file. Break out close routine from existing code.
3831 * dbxread.c (really_free_pendings): Don't free pending_blocks;
3832 they are in an obstack.
3833 (read_dbx_symtab): Relocate end_of_text_addr in the psymtab.
3835 (define_symbol): Add symbol type parameter; change callers;
3836 pass type parameter to DBX_PARM_SYMBOL_CLASS macro to allow
3837 it to influence the symbol class on the i960.
3838 (define_symbol): Swap LOC_CONST's into target byte order.
3840 * exec.c (exec_close): New function.
3841 (exec_file_command): Call it.
3843 * findvar.c (read_relative_register_raw_bytes): Doc byte order,
3844 Fix byte order of frame pointer.
3845 (read_var_value): Result of 0 if var's value can't be found,
3846 e.g. missing FRAME_ARGS_ADDRESS. Byte-swap LOC_CONST and
3847 LOC_LABEL values to target order. Add LOC_LOCAL_ARG.
3848 (locate_var_value): Use read_var_value and use its lazy address
3849 as the location of the var's value. Lint.
3851 * i960-pinsn.c (next_insn): Add routine from vxgdb for scanning
3854 * i960-tdep.c (arg_address, i960_frame_find_saved_regs): Remove
3855 obsolete Intel versions in favor of vxgdb versions.
3856 (check_host, byteswap, byteswap_val, reorder_val): Eliminate
3857 code dealing with byte order of values, which Intel did in host byte
3858 order rather than gdb-4's target byte order.
3859 (i960_frame_chain_valid): Move to nindy-tdep.c.
3860 (examine_prologue, skip_prologue, frame_find_saved_regs,
3861 frame_args_address, leafproc_return, saved_pc_after_call,
3862 pop_frame): Add vxgdb versions from Mark Fox.
3863 (examine_prologue, frame_struct_result_address): Add code
3864 to deal with the saved value of G13 (struct return address
3866 (frame_args_address): Modify Mark's version to prefer the
3867 saved value over the current value in the topmost frame.
3868 Cache result in the frame info to avoid performance hair in
3870 (print_fault): Add gdb960 code for printing faults.
3871 (_initialize_i960): Actually call check_host.
3873 * ieee-float.c (ieee_extended_to_double, ieee_double_to_extended):
3874 add stub routines. FIXME, these currently just return zero!
3876 * infcmd.c (program_info): Use PRINT_RANDOM_SIGNAL.
3877 (attach_command): Call target_attach, not target_open, now.
3879 * infrun.c (normal_stop): Make global, not static, for vx_attach.
3880 (child_attach): Rename from child_open.
3881 (wait_for_inferior): Use PRINT_RANDOM_SIGNAL. If stop_pc is zero,
3882 don't confuse it with a zero step_resume_break_address.
3884 * inftarg.c (child_detach): Eliminate inferior_pid test.
3885 (child_files_info): Clean up message a bit.
3886 (child_ops): Use child_attach, not child_open, to attach.
3888 * mem-break.c: #ifdef out the whole file if BREAKPOINT is not
3889 set (e.g. on VxWorks or NINDY). Move read_memory_nobpt from
3890 findvar.c to here, since it depends on the contents of the
3891 shadow_contents of breakpoints, but keep if #if 0 since it is
3894 * nindy-tdep.c: New file, contains nindy_frame_chain_valid, moved
3897 * printcmd.c (address_info): Handle LOC_LOCAL_ARG. Lint.
3898 (ptype_command, display_command): Eliminate have_inferior_p and
3899 have_core_file_p in favor of target_has_stack or
3900 target_has_execution.
3901 (print_frame_args): Handle LOC_LOCAL_ARG. Eliminate duplicate
3902 code for actually finding the values of arguments, though we still
3903 keep track of the maximum stack offset for use in printing unnamed
3904 arguments. Handle missing FRAME_ARGS_ADDRESS.
3906 * remote-nindy.c (i960_print_fault): Move to i960-tdep.c.
3907 (struct nindy_regs): Define registers passed to/from nindy.
3908 (nindy_fetch_registers, nindy_store-registers): Translate between
3909 nindy and GDB formats for the registers.
3910 (dcache_init): Statically allocate the cache, since it was being
3911 allocated by a malloc that was never freed anyway.
3912 (nindy_create_inferior): Error, not core dump, if no exec file.
3913 (nindy_before_main_loop): Use target_load, not target_add_file.
3915 * remote-vx.c (net_load): Specify large timeout for load
3916 requests. Allow user to break out with INTERRUPT.
3917 (net_break): Remove useless code, clean up. Change callers.
3918 (parse-args, skip_white_space, find_white_space): Clean up arg
3919 parsing to cope with quoted strings.
3920 (net_wait, net_quit): Never call error, just return status.
3921 (vx_read_register, vx_write_register): Cleanup status checking.
3922 #ifdef the code based on which CPU we are using (960 or 68k),
3923 FIXME, this should be completely general but it isn't yet.
3924 (vx_xfer_memory, vx_resume): Cleanup status checking.
3925 (vx_run_files_info): Improve message.
3926 (vx_load_command): Renamed from vx_add_file_command. Allow load
3928 (net_ptrace): Remove unused routine.
3929 (vx_wait): Adopt code from vxgdb960 to cope with broken
3930 connections to target machine and prompt to disconnect. Remove
3931 debug printouts. Map some EVENT_'s to SIGnals.
3932 (add_symbol_stub, vx_open): Print names of object files we found,
3933 and "ok" if we read their symbols OK. Clarify output in general.
3934 (vx_attach, vx_detach, vx_kill): Add these commands.
3935 (vx_convert_from_virtual, vx_convert_to_virtual): Simplify.
3936 (vx_run_ops): Turn off all_mem, to avoid spurious msg in the
3937 "info files" output, and create_inferior, since we already have
3940 * stack.c (frame_info): Replace Frame_unknown with 0.
3941 (print_frame_arg_vars): Handle LOC_LOCAL_ARG.
3942 (return_command): Pop until the PC matches as well as the FP,
3943 so it works even if the FP is shared with another function,
3944 as in "frameless" or "leaf" procedures.
3946 * symfile.c (load_command): renamed from add_file_target_command.
3947 (add_syms_addr_command): renamed from add_file_addr_command.
3948 (add_syms_command): Stub to call target_add_syms.
3949 (_initialize_symfile): Change command names and descriptions,
3950 add-file => add-syms, and load from alias to its own command.
3952 * target.c (kill_or_be_killed, maybe_kill_then_attach,
3953 maybe_kill_then_create_inferior): Default for attempts to start
3954 a process, if one is already running, is to ask about killing
3955 it and retry if yes.
3956 (upstack_create_inferior): #if-0 it, strata obsolete it.
3957 (push_target, unpush_target, pop_target): to_close() a target
3958 before unstacking it.
3959 (target_info): Renamed from target_files_info.
3960 (_initialize_targets): Rename "i files" as "i target", accessible
3963 * target.h: Improve comments about the target_ vectored routines.
3965 * tm-i960.h: Remove NINDY-specific stuff to tm-nindy960.h.
3966 Convert commenting style to standard GNU style.
3967 (DBX_PARM_SYMBOL_CLASS): allow LOC_LOCAL_ARG's to be recognized.
3968 (SKIP_PROLOGUE): No longer a no-op.
3969 (SAVED_PC_AFTER_CALL): Now handles leaf procedures.
3970 (*_REGNUM): Sort register numbers.
3971 (REGISTER_BYTES, REGISTER_BYTE, REGISTER_RAW_SIZE,
3972 MAX_REGISTER_RAW_SIZE, REGISTER_CONVERTIBLE,
3973 REGISTER_CONVERT_TO_VIRTUAL, REGISTER_CONVERT_TO_RAW): Float regs
3974 are now 10 byte extendeds, not 8 byte doubles.
3975 (FRAME_CHAIN_VALID): Make this config-dependent, since it differs
3976 for nindy versus vxworks targets. FIXME, this should possibly go
3977 in the target vector.
3978 (EXTRA_FRAME_INFO, INIT_EXTRA_FRAME_INFO): Cache both
3979 frame_saved_regs and arg pointer with each frame.
3980 (FRAMELESS_FUNCTION_INVOCATION): New leafproc support.
3981 (FRAME_ARGS_ADDRESS): Use cached result.
3982 (FRAME_ARGS_ADDRESS_CORRECT): New, avoids g14 guessing.
3983 (FRAME_FIND_SAVED_REGS): Change arg to subsidiary fn.
3984 (PRINT_RAMDON_SIGNAL): Call print_fault.
3985 (POP_FRAME): Now works.
3987 * tm-nindy960.h: Break this off tm-i960.h. NINDY-specific
3988 option parsing and startup; STACK_END_ADDR, FRAME_CHAIN_VALID,
3989 BREAKPOINT, and DECR_PC_AFTER_BREAK are here.
3990 (ADDITIONAL_OPTION_HANDLER): use target_load, not
3993 * tm-vxworks960.h: Break this off tm-i960.h. VxGDB specific
3994 startup; DECR_PC_AFTER_BREAK, and FRAME_CHAIN_VALID are here.
3996 * valarith.c (value_subscripted_rvalue): Avoid handling
3997 floats and doubles specially; it gave alignment errors. Lint.
3999 * valops.c (value_of_variable, value_of_this): Error if unknown
4002 * valprint.c (print_floating): Bcopy rather than pointer-deref,
4003 to avoid alignment problems.
4004 (value_print): Handle unknown value address.
4005 (cplus_val_print): Two args are ignored; remove them. Change caller.
4006 (val_print): Use unpack_long rather than pointer-deref.
4009 (unpack_long, unpack_double): Use bcopy rather than pointer-deref
4010 to avoid alignment problems.
4011 (value_being_returned): Error if return value unknown.
4012 (set_return_value): Add bogosity warning, FIXME. *
4014 * TODO: A woman's work is never done.
4016 * Makefile.dist: Distribute REMOTE_OBS into tconfig files.
4017 Separate INCLUDE_CFLAGS for use with lint. Add LINTFILES.
4018 Add ieee-float.o to OBS.
4019 * tconfig/{nindy960,vxworks68,vxworks960}: Include the desired
4020 REMOTE_OBS remote-interface files in the TDEPFILES and TM_FILE.
4021 * tconfig/i960: FIXME. Half-merge, produce warning if config'd.
4023 Changes to generalize the VxWorks RPC protocol slightly, to handle
4024 i960 as well as 68000.
4026 * vx-share/dbgRpcLib.h (VX_SOURCE_STEP): Add.
4027 * vx-share/reg.h: Produce i960 regs #ifdef I80960
4028 * vx-share/xdr_ptrace.c: Skip FPA registers if 960.
4029 * vx-share/xdr_rdb.h: Add SOURCE_STEP struct and xdr decl.
4030 * vx-share/xdr_rdb.c: Add xdr_SOURCE_STEP routine.
4031 * vx-share/xdr_regs.c: Add xdr_regs, xdr_fp_status, xdr_ext_fp
4032 for i960. Change xdr_vectors to xdr_opaques for 68k registers,
4033 so they will move in target byte order rather than network
4034 byte order (happens to be the same).
4036 Mon Feb 25 03:41:44 1991 John Gilmore (gnu at cygint.cygnus.com)
4038 * tm-convex.h (END_OF_TEXT_DEFAULT): Remove #if 0'd block.
4040 Sun Feb 24 00:55:53 1991 John Gilmore (gnu at cygint.cygnus.com)
4043 Add contribution lines to various files, showing where they
4046 * breakpoint.c (break_insn, check_break_insn_size,
4047 read_memory_nobpt): Remove to mem-break.c.
4049 * xm-*.h, param-no-tm.h, tm-29k.h, valprint.c: Change BYTE_ORDER to
4052 * tm-29k.h (STAB_REG_TO_REGNUM): Warn user if symbol table
4053 entry has bad register number. This change is not
4054 tested in this release, FIXME.
4056 * frame.h: Eliminate Frame_unknown in favor of a simple zero.
4059 * value.h: Force value's contents field to be aligned to hold
4060 at least a double or a long long (if supported). This avoids
4061 doing bcopy's in and out of the contents field.
4063 (step_1): Avoid coredump under obscure circumstances when we
4066 * symtab.h (misc_info): Add field to misc function vector for
4067 any kind of cached information the target code desires. AMD
4068 29000 uses this to avoid repeating examine_function_prologue's.
4070 * coffread.c: Lint. Remove static symfile, read_section_header.
4071 core.c (have_core_file_p): Lint: remove.
4072 expprint.c (print_subexp): Lint.
4073 infptrace.c, valops.c, valprint.c: lint.
4075 Roll in changes from vxgdb-5.0.1:
4077 * symtab.h: Comment byte order of each address class. Add
4078 LOC_LOCAL_ARG for frame-relative args (960).
4079 expread.y: Use LOC_LOCAL_ARG where LOC_ARG is used.
4080 symtab.c, symmisc.c: ditto.
4082 * infrun.c (init_wait_for_inferior): Clear stop_signal.
4084 * remote.c (remote_resume): Error if resume with a signal.
4086 * symfile.c (prim_record_misc_function): Clear misc_info.
4087 (fill_in_vptr_fieldno): Check stub type of arg.
4089 * valops.c (value_cast): Avoid looking up names of types whose
4090 name we don't know, to prevent coredump. Sun CC produces typedef
4091 rtx and the name of *rtx is zero...
4093 Mon Feb 18 21:16:25 1991 John Gilmore (gnu at cygint.cygnus.com)
4095 Roll in changes from final AMD 29000 port (Tiemann).
4097 tconfig/am29k: Add COFF_ENCAPSULATE and TARGET=TARGET_AM29K
4098 for ../include/a.out.encap.h. This might not work now that BFD
4099 is separately compiled. Instead, BFD support for encap will have
4100 to translate machine type 29k into the right COFF_MAGIC.
4102 * infcmd.c: Remove references to inferior_pid that aren't used
4103 in actual ptrace calls; use target_has_execution, etc.
4104 (have_inferior_p): Remove function.
4105 (program_info): Print target info rather than "process number";
4106 avoid gratuitous messages unless from_tty.
4107 (run_stack_dummy, finish_command): Set proceed_to_finish.
4108 infrun.c: Remove inferior_pid refs. Decl & init proceed_to_finish.
4109 main.c: Lint. Lose have_inferior_p().
4110 inferior.h (have_inferior_p): Remove, lint.
4111 (proceed_to_finish): Add flag to ask that all regs be saved
4112 by normal_stop, for the few commands that need it, speeding up
4113 serial I/O. Add comments to stop_registers.
4115 * remote-eb.c: Remove newline from breakpoint message we grep
4116 for. Never time out when running the user program.
4120 Wed Feb 13 15:34:40 1991 John Gilmore (gnu at cygint.cygnus.com)
4122 Roll in changes from vxgdb-5.0.1:
4124 * dbxread.c (read_dbx_symtab): If we encounter a "FORTRAN COMMON"
4125 symbol in its raw form, we are processing an unlinked ".o" file.
4126 See if the target environment has assigned it an address, using
4127 target_lookup_symbol (VxWorks does), and enter it into the symtab
4130 * tm-vxworks.h (FRAME_CHAIN, FRAME_CHAIN_VALID): Override usual
4131 68k versions for a simpler version that assumes zero FP at bottom.
4132 Fixes bug of truncated stack reports.
4134 * target.h (target_lookup_symbol): Define this routine's args
4135 and result, finally.
4137 * target.c (nosymbol): Default routine for target_lookup_symbol.
4138 (target_default): Default lookup_symbol and call_function too.
4139 (files_info): Only print has_all_memory warning if a non-dummy
4142 * remote-vx.c (vx_read_register, vx_convert_to_virtual,
4143 vx_convert_from_virtual): If target does not have floating point,
4144 zero register "values", and avoid doing cross-net conversions.
4145 (vx_lookup_symbol): Rename net_lookup_symbol, add to vectors.
4146 (vx_open): Rearrange code that attaches to target and reads
4147 symbols for all loaded modules, to work if some of the modules
4148 are not accessible. Add symbol_stub() and add_symbol_stub()
4149 as callbacks from catch_errors(). Allow connect attempt to be
4150 interrupted painlessly with ^C (FIXME, there are still some bugs
4151 if the interrupt happens during symbol reading.). Print
4152 final message with puts_filtered, since symbol messages are
4157 * main.c (catch_errors): Only print errstring if non-null.
4158 (command_loop): Avoid an ioctl per command to test ISATTY.
4160 * remote-vx.c (net_load): make static; avoid sophomoric msg.
4161 (vx_xfer_memory): Return correct result!
4162 (vx_files_info): Indicate whether target has float or not.
4163 (vx_lookup_symbol): Complain, not error, if target gone.
4164 (vx_open): Print "Connected" msg before disabling immediate-quit.
4165 [FIXME: lookup_symbol and vx_open changes need testing.]
4167 target.c, remote-eb.c, inftarg.c, am29k-opcode.h, target.h,
4168 tm-29k.h, tmm-vxworks68.h, symfile.c, gdb-int.texinfo: Add
4169 contributor lines and update copyrights to 1991.
4171 Changes from an attempted H-PUX host port:
4173 * infptrace.c (PT_ATTACH, PT_DETACH): Handle HP/UX, which
4174 defines PT_ATTACH and PT_DETACH but not PT_KILL.
4175 * remote-eb.c (eb_open): Misplaced endif kills sysv H/PUX.
4176 * remote-vx.c: include <sys/time.h> for HPUX.
4177 * hp300hpux-xdep.c (fetch_core_registers): Rewrite old
4178 "core_file_command" routine to BFD regime. May not work yet.
4180 Attempted port of "gdb-3.4 Van Jacobson xgdb" to modern gdb.
4182 * xgdb.c: Replace X10 version with some VJ version.
4183 (FIXME: Its copyright assignment is not on record.)
4184 * xgdb.c: Update include files to X11R4 (Xaw crud).
4185 (xgdb_display_source, create_text_widget): fix call to
4186 get_filename_and_charpos. Rewack source window stuff for X11R4
4187 (gleaned from include files, and "nm's" of binary libraries, since
4188 I had no doc available).
4189 (append_selection, append_selection_word): Disable with FIXME
4190 since R4 changed interface here.
4191 (create_buttons): Add back the old set of buttons.
4192 (xgdb_create_window): Fix call to XtInitialize (&argc not argc).
4194 * Makefile.dist (xgdb, xgdb-init.c): Update for X11R4 on Suns.
4195 Roll VERSION to 3.94 (not yet final though).
4197 Sat Feb 9 09:46:25 1991 John Gilmore (gnu at cygint.cygnus.com)
4199 * obstack.h (obstack_ptr_grow, obstack_ptr_grow_fast,
4200 obstack_int_grow, obstack_int_grow_fast): Eliminate
4201 cast on left of assignment, which gives MIPS cc fits and is
4204 * sparc-pinsn.c (print_insn): Eliminate 'set' test, subsumed by
4205 F_ALIAS. Use printf, not fprintf, when not passing a file
4207 (compare_opcodes): Check that identical instructions have
4208 identical opcodes, complain otherwise.
4210 * sparc-opcode.h (st %fsr): Fix opcode "lose" mask. This
4211 was reported by Roland McGrath.
4212 (unimp): Only match if exactly zero instruction. (Roland)
4213 (branches and traps): Generate all variations of these
4214 instructions with macros, based on a single call that defines
4215 each condition name and its binary representation.
4216 (set): Turn on alias bit, to avoid test in sparc-pinsn.c.
4218 * valprint.c (val_print_fields): Take, and use, format parameter.
4219 This means that "p/x struct" again prints the elements in the
4220 desired format. Changed callers.
4222 * stack.c (frame_info): Use filtered output, and indicate wrap
4223 points. Remove kludgy formatting designed to avoid line wrap.
4225 * utils.c (wrap_here): If the line is already full (because
4226 we had printed a long indent or long wrapped string), do an
4227 immediate newline-and-indent.
4229 * m68k-pinsn.c (print_insn_arg): Bugfix from
4230 ntmtv!thompson@ames.arc.nasa.gov (Mike Thompson): 'bkpt #0'
4231 instruction is incorrectly disassembled as bkpt #8.
4233 * dbxread.c (end_psymtab): Bugfix from Peter Schauer
4234 <pesrem@regent.e-technik.tu-muenchen.de>: If you want to set a
4235 breakpoint in a *.y file gdb will say Reading in symbols for *.y...
4236 and then will dump core (sometimes). I traced it back to an
4237 uninitialized symfile_name in psymtab_to_symtab.
4238 (const_vol_complaint): Add quotes to message.
4239 (define_symbol): Only believe line number if gcc_compiled.
4240 Avoid allocating symbol if we will not return it.
4242 Add target strata support so that newly established targets go
4243 into their right place in the target stack (e.g. a new exec file
4244 doesn't wipe out the ability to access the running process).
4246 * target.h, core.c, exec.c, inftarg.c, remote-eb.c,
4247 remote-nindy.c, remote-vx.c, remote.c, target.c: Add to_stratum
4248 and initialize it properly in all the targets.
4250 * target.h: Document strata. Change return type of push_target.
4252 * target.c (nomemory): new function for dummy memory access.
4253 (tcomplain): Rename complain, now also used in symfile.c.
4254 (push_target): Push targets within strata. New return value shows
4255 whether new target is on top of stack or not. Always keep dummy
4257 (target_files_info): Ignore dummy target.
4259 * core.c (core_open): Warn user, and skip accessing file, if the
4260 core target is not the topmost target in the stack.
4261 * remote-nindy.c (nindy_create_inferior): Avoid unpush_target, now
4264 * remote-vx.c: Remove vx_prepare_to_store from vxworks memory
4265 target_ops, it doesn't belong there since we have no regs there.
4266 Change name of target from machine => memory to clarify.
4268 Thu Feb 7 16:32:09 1991 John Gilmore (gnu at spiff.cygnus.com)
4270 * Freeze version 3.93 for release.
4272 * Makefile.dist: Handle vx-share and nindy-share subdirs
4273 properly when building gdb.tar.Z.
4275 * symtab.c: lint; add no_symtab_msg to consolidate the messages
4276 printed in various places, so I could change just one copy.
4278 * dbxread.c, coffread.c: Change references to bfd->iostream
4279 to cast to FILE *, now that BFD avoids needing types defined
4280 in other header files.
4282 Tue Feb 5 21:39:35 1991 John Gilmore (gnu at cygint.cygnus.com)
4284 * command.c, dbxread.c, expprint.c, infcmd.c, infptrace.c,
4285 infrun.c, printcmd.c, remote-nindy.c, source.c, sparc-tdep.c,
4286 sparc-xdep.c, symfile.h, symmisc.c, utils.c, valprint.c: Lint
4287 (actually gcc -Wall).
4289 * dbxread.c: Remove first_global_sym, last_global_sym, since
4290 they are never referenced.
4292 * defs.h (baud_rate): Declare.
4293 main.c: Define it, and add the -b option to set it.
4295 * gdb-int.texinfo: Add text on how to define a new host or target
4296 architecture, prompted by Per Bothner's questions about MIPS
4299 * gdb.texinfo: Document "complaints". Change doc of -q since
4300 gdb no longer prints the copyright and blurb if you specify a file
4301 name to be debugged (just like Emacs). Add doc for Nindy-specific
4302 command line flags for specifying target serial port and such.
4303 Update copyright to 1991.
4305 * gdbcore.h: Remove a large mass of now-useless crud, since BFD
4306 has taken over for us the job of ripping up executable files. The
4307 crud caused Per Bothner's port to not compile.
4309 * infrun.c (normal_stop): Avoid printing "Program exited
4310 normally" if we are in batch mode. This allows a GDB which
4311 executes a program on a target system, to behave like a Unix
4312 command (input from stdin, output to stdout, no extraneous
4315 * main.c (main): Allow additional machine-dependent command line
4316 options to be specified with the ADDITIONAL_OPTIONS,
4317 ADDITIONAL_OPTION_CASES, ADDITIONAL_OPTION_HELP, and
4318 ADDITIONAL_OPTION_HANDLER macros. Also allow machine-dependent
4319 processing to occur just before the main loop with
4320 BEFORE_MAIN_LOOP_HOOK.
4321 (main): If a "core file" argument is specified, and it is not a
4322 core file, try it as a process ID to attach.
4323 (symbol_completion_function): Attempt to cope with
4324 "show screen-" TAB, not very successfully. This needs more work,
4326 (batch_file): New function, returns whether we are reading
4327 commands from an interactive tty on stdin, or from somewhere else.
4328 Called by normal_stop since it doesn't get from_tty passed down
4329 to it like many commands do.
4331 * remote-nindy.c: Handle command line options for nindy
4333 (nindy_before_main_loop): Prompt user for tty name if they
4334 don't specify it before getting to the interactive command loop.
4336 * tm-i960.c: Add ADDITIONAL_OPTIONS, etc, to handle -O, -brk,
4337 and -r command line options. Also add hook before main loop
4338 to make it easy to specify a tty.
4340 * TODO: More things to do, one done.
4342 Mon Feb 4 23:57:39 1991 John Gilmore and Mike Tiemann (at cygint.cygnus.com)
4344 * dbxread.c: Make complaint() calls pass pointer, not struct.
4345 Add complaints about badly formatted C++ type information
4346 (const/volatile indicator, and parse errors resulting in
4347 error_type). Fix C++ virtual member fn comment.
4348 (read_struct_type): Avoid bumping pointer if we got a parse
4349 error; this prevents our walking beyond the end of a string.
4350 Terminate loop on null char as well as semicolon.
4351 (process_one_symbol): Fix the LBRAC fix so that it uses the
4352 last previous SLINE, FUN, or SO record's PC address. C++ debug
4353 symbols did not have SLINE records in a useful order compared
4354 to the LBRAC records.
4355 (define_symbol): Handle "catch" records.
4357 * symtab.c (check_stub_type): Added new complain
4358 `stub_noname_complain' and added a consistency check to
4359 keep the debugger from crashing when finishing from an
4360 exception frame. A real fix will be needed later.
4362 Sat Feb 2 10:43:05 1991 John Gilmore (gnu at cygint.cygnus.com)
4364 * infcmd.c (attach_command): Make global.
4366 * Makefile.dist (REMOTE_OBS): Make these compile by default,
4367 but make them easy to comment out. Perhaps later they should
4368 be enabled by what CPU you configure for? FIXME.
4369 (VERSION): Roll to 3.93.
4370 (pinsn.o): Remove rule for obsolete file.
4371 (dbxread.o,coffread.o,mipsread.o): Use ${srcdir} explicitly.
4373 Run down a problem that manifested by printing the wrong function
4374 name in stack traces of read_ofile_symtab. Turned out that the
4375 problem was the SunOS 4.1.1 (and previous) C compiler outputs
4376 the LBRAC symbol with an address in the *data* segment, which
4377 blew our binary search through the blocks.
4379 * dbxread.c: Use the complain() facility consistently to bitch
4380 about problems in the symbol file we are reading.
4381 (finish_block): Add code to check the nesting of the blocks;
4382 complain and Procrust them to fit if wrong.
4383 (make_blockvector): Check the order of the blocks, complain
4384 [but don't cope] if wrong.
4385 (process_one_symbol): ifndef SUN_FIXED_LBRAC_BUG, check LBRAC
4386 symbols to be sure their PC value is greater than the last SLINE
4387 (line number) symbol we've seen, complaining and adopting the
4388 SLINE PC value if wrong.
4390 * symfile.h (struct complaint, complaint_root, complain,
4391 clear_complaints): Add.
4392 * symfile.c (complain, complaint_root, clear_complaints): Add
4393 facility to deal with non-fatal complaints and to regularize their
4395 (symbol_file_add): Clear complaint counters to allow new complaints.
4396 (initialize_symfile): Add 'set complaints' and 'show complaints'.
4398 * dbxread.c (dbx_symfile_read): Remember the address and size
4399 of the string table for the main symbol file, so we won't read it
4401 (dbx_psymtab_to_symtab): Fix the check for main symbol file,
4402 to avoid reading the string table yet again. Lint.
4403 (throughout): Improve filtered output, including word wrap.
4404 (read_range_type): Improve Bothner's fix to handle other types too.
4406 * utils.c: Improve line wrap implementation. Handle unlimited
4407 width by making chars_per_line unsigned.
4408 (puts_filtered): New, easy, function.
4410 * defs.h (puts_filtered): add.
4412 * mipsread.c (compare_symbols, sort_symtab): Remove these fns,
4413 call the identical sort_symtab_syms() in symfile.c instead.
4415 * expread.y: Suggest the `file' command rather than `symbol-file'.
4417 * command.h (enum var_types): Add zinteger for seroable
4419 * command.c (do_setshow_command): Handle var_zinteger. Restructure
4420 nested if's into a switch.
4422 * breakpoint.c (bpstat_print): If bpstat "print" flag is not set,
4423 we did not stop because of a breakpoint (it must have been for
4424 some other reason, like a "stepi"), so don't print anything.
4426 * symtab.c: Include <sys/types.h> all the time. Now that BFD
4427 doesn't include <sys/types.h>, old SunOS's require it for
4430 Sat Feb 2 10:39:15 1991 Per Bothner (bothner@cs.wisc.edu)
4432 A test port of gdb-3.92.6 to the Sony NEWS.
4435 Don't normally link in remote- or vx stuff.
4436 Some of it doesn't compile, and it wastes space for 99% of the users.
4437 Remove reference to no-longer-used HAVE_VPRINTF.
4438 Fixed BFD_DEP typo to BFD_DIR.
4440 Fix cast in arg to bfd_h_getlong.
4441 Make char *prefix be const.
4442 Fix how certain range types are mapped into builtin unsigned int types.
4444 Remove 2 #includes. They cause errors (on Sony, at least),
4445 and aren't needed (they wern't in earlier versions).
4447 print_address_symbolic should never demangle labels
4448 (since it prints *assembler-level* labels).
4450 [This was superseded by the change to printcmd below.]
4453 Add some "volatile" return types to avoid warnings.
4454 If MISSING_VPRINTF add vprintf function and not just macro
4455 (since vprintf is used in printcmd.c).
4457 Unless __GNUC__, use obstack_grow instead of obstack_ptr_grow.
4458 (The latter isn't grokked by some PCC-based compilers.)
4460 [This change is in abeyance, we prefer to fix obstack_ptr_grow.]
4462 Make chunk size of dont_print_obstack 32*4 instead of default 4096.
4463 * nindy-share/coffstrip.c
4464 Added some forward declarations (otherwise, gcc complains
4465 about implicit extern redefined as static).
4467 Sun Jan 20 02:38:19 1991 John Gilmore (gnu at cygint.cygnus.com)
4469 Changes inspired by Per Bothner:
4470 * printcmd.c (print_address_symbolic): Take additional parameter
4471 specifying whether to demangle.
4472 (print_address): Pass in asm_demangle to control demangling.
4473 (print_address_demangle): New fn, takes explicit arg to control
4475 * utils.c: Add new vars demangle and asm_demangle, and let them
4477 (fputs_demangled): If !demangle, just print the argument.
4478 (fprint_symbol): If !demangle, just print raw symbol.
4479 * valprint.c (val_print): Call print_address_demangle rather than
4480 print_address, to cause demangling to depend on the global
4481 rather than assembler-level demangling setting.
4482 * WHATS.NEW, gdb.texinfo: Document.
4484 * main.c (show_command): Show all settings if no arg.
4485 (initialize_main): Make "info set" the same as naked "show".
4486 * command.c (cmd_show_list): Handle prefix commands in the
4487 list, and print the name of the setting as well as its English
4488 description and value.
4490 Allow gdb functions to specify where a line should wrap if it
4491 exceeds the size of a terminal line. Use it to make the output
4493 * utils.c (set_screen_width_command): New fn, mallocs a buffer
4494 of the right size when screen width changes.
4495 (set_screensize_command, screensize_info): Remove #if 0'd fns.
4496 (wrap_here): New fn, indicates a point in the output where we
4497 should wrap the line rather than just letting it overflow at a
4499 (fputs_filtered): Implement wrapping.
4500 (n_spaces): New fn, returns a pointer to N spaces.
4501 (print_spaces_filtered): Use n_spaces.
4502 * defs.h (n_spaces): Declare.
4503 * stack.c (print_frame_info): Wrap with 4-space indent after
4504 fn name and before filename and line number.
4505 * printcmd.c (print_frame_args): Wrap with 4-space indent
4506 before each argument name is printed.
4507 * valprint.c (value_print): Wrap with no indentation before
4509 (val_print_fields): Wrap with indentation relative to nesting
4510 level before each field name.
4511 (val_print): Wrap with nesting indentation before array elements.
4512 * command.c (do_setshow_command): Avoid extra newlines,
4513 wrap with 4-space indent around values printed, end with period.
4514 * WHATS.NEW, gdb.texinfo, gdb-int.texinfo: Document.
4516 * breakpoint.c (breakpoint_1): Implement addressprint for
4517 "info breakpoints" display. Change file name and line number
4518 format to " at file:nnn" rather than " (file line nnn)".
4519 * gdb.texinfo: Document.
4522 Fri Jan 18 07:21:25 1991 John Gilmore (gnu at cygint.cygnus.com)
4524 Frozen for gdb-3.92.6 release.
4526 README, WHATS.NEW: Update for 3.92.6 release.
4528 tconfig/{altos, i386v, i386v32, m88k, umax}: Eliminate
4529 coffread.o from configs since it is now built by default.
4530 tconfig/{3b1, altosgas, arm, convex, hp300bsd, hp300hpux,
4531 i386v-g, i386v32-g, isi, merlin, news, news1000, np1, pn,
4532 pyramid, symmetry, vax, vxworks68}: Eliminate dbxread.o
4533 from configs since it is now built by default.
4535 Makefile.dist: Update for release 3.92.6. Handle files that
4536 have been moved to ../include, ../getopt, or ../bfd. Add
4537 saber.suppress and tests directory. Add config.status to
4538 the release (it will say "none").
4540 coredep.c: Minor formatting fixes.
4542 These changes were made in early December but only checked in now:
4543 * nindy-share/Onindy.c, nindy-share/coffstrip.c,
4544 nindy-share/nindy.c: lint
4545 * nindy-share/nindy.c (ninStopWhy): Don't byteswap the
4546 register values coming back from the target; we store values
4547 in target byte order everywhere.
4549 Wed Jan 16 19:01:37 1991 John Gilmore (gnu at cygint.cygnus.com)
4551 * am29k-opcode.h, am29k-pinsn.c: Add 29050 opcodes.
4553 * valprint.c (cplus_val_print, val_print_fields): New functions,
4554 which print C++ objects. They conspire to avoid printing a
4555 virtual base class more than once, following all the twists and
4556 turns of C++ virtual base rules.
4557 (val_print): Call the above rather than do it by hand.
4559 * symfile.c (symbol_file_add): Only reset symfile_mtime for main
4560 symbol file, not for added files like shared libs. This really
4561 needs to be generalized to a timestamp per file.
4563 * core.c (cleanup_core): Avoid coredump if no core file.
4565 * config.gdb: Accept -host or -target in place of +host or
4568 * coffread.c (find_linenos): Avoid desupported BFD interface
4569 to line numbers. We still read them manually rather than using
4570 BFD's "generic" features.
4572 * gdbrc.tex, threecol.tex: Add GDB reference card and its
4574 Makefile.dist: Add refcard to OTHERS list for creating tar files.
4576 * Makefile.dist: Eliminate use of $< in explicit targets.
4578 * readline/Makefile: Use $< rather than $*.c, which does not
4579 include the VPATH in GNU Make.
4581 * tconfig/i960-bout, tconfig/i960-coff: These are identical
4582 copies of tconfig/i960, added for global configuration
4583 compatability. All i960 versions can read both coff and b.out.
4585 * tm-88k.h: Fix multiline macro that lacked \'s. Remove
4586 COFF_FORMAT and COFF_CHECK_X_ZEROES since these are now handled
4589 * TODO: Think of more things to do.
4591 Wed Jan 2 19:09:29 1991 John Gilmore (gnu at spiff.cygnus.com)
4593 tconfig/{am29k,i960,sun2*,sun3*,sun4*}: Eliminate config
4594 of sdb versus dbx debug symbols. Add kludge for 68881 80-bit to
4595 64-bit float conversion.
4597 tconfig/sun4, tconfig/sun3, xconfig/sun4, xconfig/sun3: Make
4598 equivalent to sun?os4 so global config works.
4600 Wed Jan 2 18:20:51 1991 John Gilmore (gnu at spiff.cygnus.com)
4602 Fix from Eberhard Mattes <mattes@azu.informatik.uni-stuttgart.de>
4604 * main.c: Only declare linesize once; declare pagesize not at
4605 all, since it is never used.
4606 (main): Clear newly allocated line before it is used.
4608 Fri Dec 28 00:13:42 1990 John Gilmore (gnu at cygint)
4610 Further stabilization for the Intel 960.
4612 * Makefile.dist: Parameterize the location of the "include"
4613 and "bfd" directories, as well as "getopt". Add symfile.c.
4614 Link in both dbxread and coffread. Fix up "make depend" to
4615 rewack the locations of include, bfd, and getopt in its output.
4617 * README: Document moving include files, improve some of
4620 * coffread.c: Move common code out to symfile.c. Change
4621 symbol_file_command style interface to use new *_symfile_init
4622 and *_symfile_read interface under BFD. Use BFD internal
4623 info to locate line table, symbols, etc.
4625 * core.c (core_fetch_registers): Rename to get_core_registers
4626 to avoid confusion with fetch_core_registers.
4627 (register_addr): Move to coredep.c, which is already machine
4628 dependent. This leaves core.c pretty clean of dependencies.
4630 * coredep.c (register_addr): Accept this routine from core.c.
4632 * dbxread.c: Move common code (with coffread.c, etc) into new
4633 symfile.c. Each psymtab now contains a pointer to the
4634 format-dependent function that knows how to read it in. Make
4636 (dbx_psymtab_to_symtab): Renamed from psymtab_to_symtab_2.
4637 (process_one_symbol): Add code to complain about a "compiler bug
4638 we muzzle here", if we actually see it.
4640 * eval.c (evaluate_subexp): Insert missing "break" statements
4641 in code that determines whether a variable is an lvalue in
4642 memory, register, or whatever. I detected this via a compiler
4643 bug in which it *almost* mashed out the whole switch statement.
4645 * gdb-int.texinfo: Add minor sections on configuring gdb for
4646 release, and about the README file.
4648 * infcmd.c (registers_info): Fix formatting somewhat. Still
4649 not as pretty as before, but it handles byte swapping.
4651 * remote-nindy.c: If data cache routines are interrupted while
4652 waiting for the remote end, be sure that any uninitialized cache
4653 blocks are on the free list, not on the valid list!
4655 * symfile.h: Flesh out this header file with all the various
4656 routines and variables that have been merged in from dbxread.c
4657 coffread.c, and symtab.c to symfile.c.
4659 * symfile.c: New file, containing code common to dbxread.c,
4660 coffread.c, and some code from symtab.c. All generic code for
4661 reading symbol files should be in here now.
4662 (unrecord_misc_function): Remove unused function.
4664 * symtab.h: Remove file-reading things to symfile.h.
4666 * symtab.c: Remove file-reading things to symfile.c.
4668 * tm-i960.h: Fix FRAME_CHAIN types; define PRINT_RANDOM_SIGNAL
4669 to decode i960 fault types.
4671 * target.h, remote.c, remote-eb.c, remote-vx.c, remote-nindy.c,
4672 target.c: Change type of the "resume" function from int to void,
4673 since its result was never used.
4675 Sat Dec 22 02:51:40 1990 John Gilmore (gnu at cygint)
4677 * main.c: Replace "stupid" with "caution"; you now "set caution
4680 * printcmd.c (print_scalar_formatted): Fix typo in 'g' format
4682 * infcmd.c (do_registers_info): Call val_print to deal with the
4683 byte order of the registers being printed. FIXME, this makes
4684 the formatting of the output uglier.
4686 * infcmd.c (wait_for_inferior): If PRINT_RANDOM_SIGNAL is
4687 defined, call it for signals the debugger doesn't itself use.
4688 The i960 uses this for more detailed fault information.
4690 * remote.c (remote_open): If arg is null, print help rather than
4693 * sparc-xdep.c (register_valid): Avoid declaring size, since
4694 various modules will think of various sizes depending on the
4695 architecture of their tm-file. FIXME, we need protection against
4696 actually entering one of those modules, which would clobber
4697 storage if not for the target architecture compiled into gdb.
4699 * stack.c (up_command, down_command): Always print the frame
4701 (up_silently_command, down_silently_command): New commands
4704 * i960-pinsn.c (reg), i960-tdep.c: Lint.
4706 * i960-tdep.c (i960_frame_chain_valid): Lookup_symbol now takes
4707 more parameters than it used to.
4709 * findvar.c (registers): Increase slop to 256 bytes, which should
4710 protect us against even most RISC machines with large register
4712 (locate_var_value): Move declaration inside related ifdef.
4714 * remote-nindy.c (): Use TIOCSETN rather than TIOCSETP
4715 throughout, to avoid throwing away buffered input from the board.
4716 (nindy_wait): Supply_register takes addr_of_value, not value.
4717 (i960_print_fault): Renamed from i80960_fault.
4718 (nindy_fetch_registers): Avoid have_regs stuff, just get them.
4719 (nindy_store_registers): Avoid regs_changed stuff, just stuff
4721 (nindy_create_inferior): Don't bother to write PC_REGNUM since
4722 we can set the PC in the call to proceed(). Unpush nindy_ops
4723 before pushing it on top, to avoid message to user. Eliminate
4724 commentary from Unix machines that just misleads here.
4725 (reset_command): Fix error message to suggest target command.
4727 Wed Dec 19 11:03:56 1990 John Gilmore (gnu at cygint)
4729 Release 3.92.5 as frozen.
4731 Stabilize the merged release...with help from lint, Saber C,
4734 Everywhere: Add include files needed to declare return types
4735 of functions called.
4737 * gdb.texinfo: Roland Pesch is documenting gdb, glory be!
4739 * breakpoint.h: Add undeclared breakpoint functions, and some
4740 functions for display handling since I couldn't think of a better
4743 * breakpoint.c (insert_breakpoints): Make code for disabling
4744 shared library bkpts more likely to work. It's used when we
4745 rerun a program and stop before the shared library has been
4747 (breakpoint_cond_eval, bpstat_stop_status): Pass arg as int,
4748 cast from pointer, so it squeezes through catch_errors.
4749 (bpstat_stop_status): Fix logic broken some time ago. We now
4750 always create a bpstat if the stop address matches a breakpoint,
4751 even if we don't stop there -- just like the old code used to do
4752 before I got my fingers into it (sigh).
4753 (breakpoint_1): Print "ignore count" after "stop only if"
4754 condition, since that's how it actually works.
4755 (mention): Handle watchpoints as well as breakpoints.
4756 (watch_command): use set_raw_breakpoint and mention to do most
4757 of the work (and initialize all the fields!). Only pass one
4758 arg to parse_c_expression, since that's all it takes.
4760 * command.c (not_just_help_class_command): Rename arg to args
4761 since we ignore "unused argument" warnings on vars named "args".
4762 inflow.c (child_terminal_info): ditto.
4763 infptrace.c (kill_inferior): ditto
4764 main.c (catch_errors, version_info, quit_command, pwd_command,
4765 source_command, dump_me_command, editing_info,
4766 set_history_size_command, set_history, show_history,
4768 stack.c (locals_info): ditto
4769 target.c (target_files_info): ditto
4770 valprint.c (set_input_radix, set_output_radix): ditto
4772 * core.c: Remove old variables for handling core and exec file
4773 sections (data_start, data_end, stack_start, stack_end,
4774 reg_stack_start, reg_stack_end, reg_stack_offset, text_start,
4775 text_end, exec_data_start, exec_data_end, text_offset,
4776 exec_data_offset, data_offset, stack_offset). They're
4777 superseded the more general build_section_table and
4779 (get_exec_file): Mention the `file' command.
4780 (read_memory_check): Rename to memory_error, and only call it
4781 in the case of an actual error.
4782 (read_memory, write_memory): call memory_error.
4783 (core_fetch_registers): Register section name is ".reg".
4785 coredep.c: Remove a bunch of crud now that all this file does
4786 is pull the registers out of a core file.
4787 (fetch_core_registers): Rewrite to actually work, I hope.
4789 dbxread.c: Use a.out.gnu.h, not system a.out, now.
4790 Replace index() with strchr(). Remove all the pre-BFD macro
4791 definitions for accessing the symbol file.
4792 (struct dbx_symfile_info): Encapsulate the information that
4793 dbx_symfile_init needs to pass to dbx_symfile_read in this
4796 (dbx_new_init, dbx_symfile_init, dbx_symfile_read,
4797 dbx_symfile_discard): Rearrange symbol file reading to divide
4798 the format-specific part from the format-independent part,
4799 leaving the format-independent part such as file name expansion
4800 and opening in symtab.c. This replaces
4801 partial_symbol_file_open and partial_symbol_file_read.
4802 Symbol_file_read, add_file, add_file_target_command,
4803 add_file_addr_command move to symtab.c. Pass an explicit
4804 "mainline" flag for when reading the main symbol table, rather
4805 than relying on the offset address to be zero or nonzero.
4807 (dbx_symfile_read): Don't allow void *'s to be printed as
4809 (SWAP_SYMBOL): Use bfd routines to byte-swap the symbols.
4810 (ADD_PSYMBOL_TO_LIST): Make the "function call rather than
4811 macro" debug version really work.
4812 (read_dbx_symtab): Remove unref'd parameter inclink.
4813 Avoid swapping N_SLINE symbols, for speed.
4814 Merge N_TEXT!N_EXT case with the other external symbol
4815 definitions' case. Add comments.
4816 (start_psymtab): Allocate the symfile name in the psymtab on
4817 the psymbol_obstack, rather than using the caller's storage.
4818 (end_psymtab): Only allocate a dependencies list if there are
4820 (psymtab_to_symtab_2): Use BFD when reopening file to read
4821 its symbols for real.

4824 (read_huge_number): Add FIXME about overflows.
4825 (read_range_type): Add FIXME about comparing a long to 1<<32.
4827 * coffread.c: Minor changes to move things closer to the new
4828 regime with symtab.c and dbxread.c Major work is still needed
4831 * exec.c (exec_file_command): Remove old variables (see core.c
4833 (xfer_memory): If memory transfer is right at the end of a
4834 section, don't lose.
4836 * findvar.c (get_saved_register): If value is in a real
4837 register, LVAL is lval_register, not lval_memory.
4839 frame.h: Declare print_sel_frame and record_selected_frame.
4841 gdb-int.texinfo: New file, for GDB internals documentation.
4842 Very simple, unformatted doc of cleanups is there for now.

4845 section addresses and offsets. (See core.c above.)
4846 Declare fetch_core_registers and registers_fetched.
4848 getopt.c: Declare char *alloca(); even on SPARC.
4850 infcmd.c (run_command): Call target_kill rather than
4852 (step_command, next_command, stepi_command, nexti_command):
4853 Declare from_tty parameter even though we don't use it.
4854 (run_stack_dummy): argument BUFFER is a char array, not
4855 a pointer to REGISTER_TYPE.
4856 (finish_command): using_struct_return needed a value *,
4857 not a struct symbol *.
4859 * infptrace.c (child_xfer_memory): To avoid dependency on
4860 where sections are in memory, try PT_WRITE_D and if that fails,
4861 try PT_WRITE_I. Most Unixes don't care which you use.
4863 * infrun.c (step_resume_break_shadow): Change to array to
4864 match other breakpoint shadow storage.
4865 (clear_proceed_status): Pass address of bpstat to
4866 bpstat_clear, not the bpstat itself.
4867 (child_create_inferior): FIXME comment about if the child
4869 (start_inferior): Remove old function.
4870 (child_open): Use target_kill rather than kill_inferior.
4871 (wait_for_inferior): Ditto.
4872 (insert_step_breakpoint, remote_step_breakpoint): Use
4873 new step_resume_break_shadow.
4875 * inftarg.c (child_wait): If all child processes die,

4878 * main.c (command_line_input): When scanning for comments,
4879 don't coredump on unclosed quotes.
4880 (quit_command): Use target_kill rther than kill_inferior.

4884 * printcmd.c (print_command_1): Initialize "fmt" if no format
4885 is specified by the user.
4886 (print_frame_args): Only add to args_printed if we are
4887 actually fetching args from the stack (avoiding undefined
4889 (_initialize_printcmd): Remove bogus \{ from string.
4891 * remote-eb.c (eb_open): Avoid coredump on no argument.
4893 * remote-nindy.c: Bring out of Intel environment into new
4894 target environment. Remove all conditional compilation on
4895 I80960. Massive hacking throughout.
4896 (nindy_xfer_inferior_memory): New routine stolen from
4898 (nindy_create_inferior): New routine pieced together, probably
4899 not quite working yet.
4900 (nindy_ops): New target_ops struct for nindy.
4902 * remote-vx.c: Use write_memory rather than target_write_memory
4903 to get error checking.
4904 (vx_add_file_command, vx_open): Use symbol_file_add rather than
4906 (vx_create_inferior): Use target_terminal_ours...
4908 * signame.c (_initialize_signame): Always initialize, since
4909 we need the table for things other than psignal.
4911 * solib.c (solib_add): Use symbol_file_add, not add_file.
4912 (solib_address): Return boolean result rather than struct
4913 pointer which nobody else knows the type of.
4915 * sparc-tdep.c, valops.c: Use write_memory rather than
4916 target_write_memory, to get error checking.
4918 * stack.c (locals_info, catch_info, args_info,
4919 get_selected_block, frame_command, up_command): Use
4920 target_has_stack, rather than have_inferior_p or
4923 * sun3-xdep.c (fetch_core_registers): Rewrite for new BFD regime.
4925 * symfile.h: New file, defining the interface between the
4926 generic and object-file-specific symbol reading code.
4928 * symtab.c: Move generic symbol-reading interface to symtab.c,
4929 from dbxread.c, coffread.c, mipsread.c, etc. Add symtab_fns
4930 table to map BFD targets to symbol-reading modules in GDB.
4931 Change index to strchr.
4932 (lookup_struct_elt_type): Use error() rather than hand-made
4933 simulations thereof.
4934 (lookup_partial_symbol): Speedup slightly when length == 0.
4935 (symbol_file_add): New function.
4936 (symbol_file_command): Call it.
4937 (symfile_open, symfile_init): New function.
4938 (add_file_target_command, add_file_addr_command): moved from
4941 * target.c (target_command): use target_kill.
4943 * target.h (target_files_info): Don't declare, never called
4946 * tm-sun2.h, tm-sun3.h (STACK_END_ADDR): Use system include
4947 files to determine stack end address.
4949 * valarith.c (value_x_binop, value_x_unop): Change error message
4950 to be more useful. Pass proper argument to value_struct_elt.
4952 * valops.c (value_assign): FIXME comment that long long
4953 bitfields will break here.
4955 * Makefile.dist: Add symfile.h, remote-nindy.c, remote-eb.c.
4956 Update `make saber_gdb' to work better.
4958 * TODO: A woman's work is never done.
4960 * cplus-dem.c, environ.c, inferior.h, infrun.c, inftarg.c,
4961 main.c, obstack.c, printcmd.c, remote-eb.c, remote-nindy.c,
4962 remote-vx.c, remote.c, solib.c, source.c, sparc-pinsn.c,
4963 sparc-tdep.c, sparc-xdep.c, symmisc.c, symtab.c, symtab.h
4964 target.c, terminal.h, tm-sparc.h, tm-sunos.h, utils.c,
4965 valops.c, valprint.c, exec.c: Lint.
4968 Wed Dec 12 23:44:15 1990 John Gilmore (gnu at cygnus.com)
4970 Continuing Intel 960 port merge of GDB.
4972 * Makefile.dist: Merge i960 "nindy-share" files. Rename
4973 malloc.h to gmalloc.h to avoid name conflicts in /usr/include.
4974 Don't ship gdb.dvi in tar file. Link gdb with init.o, not init.c.
4975 Wack over "make depend" so it handles files in subdirectories
4976 vx-share, nindy-share, bfd, and in the current directory.
4978 * blockframe.c (get_prev_frame_info): Remove fatal error
4979 if stack not defined.
4981 * core.c (core_open, core_detach): New functions that handle
4982 the old "core-file" command as "target core" and "detach" instead.
4983 (core_file_command): Call them.
4984 (core_xfer_memory): Use common routine xfer_memory.
4986 * dbxread.c: Include a.out.gnu.h, not system a.out.h.
4987 dbxread now uses bfd for everything but symbol reading itself.
4988 BFD internals are used to drag out the relevant file offsets.
4989 (partial_symbol_file_open): Change args all around for BFD.
4991 * symtab.c: Rename "value" to "val" everywhere, so we can
4993 (symbol_file_command): New command, moved from dbxread.c
4994 and coffread.c. It uses BFD to read the file, then vectors
4995 based on its type, to dbx or coff symbol readers.
4996 * symtab.h: Extern a few vars for symbol_file_command.
4998 * target.h: Breakpoint takes a char * save area, not a char **.
5000 * valprint.c (val_print): When unpacking bitfields, offset
5001 the address in gdb of the value, if it is declared with a shorter
5002 type. Remove the last "runtime kludge test" of host byte order.
5004 * utils.c: Remove old my_bfd_read routine.
5006 * stack.c (frame_info): Use target_has_stack. Print program counter
5007 register's actual name rather than "pc", since it's called the
5008 "ip" (instruction pointer) on the i960 (sigh).
5010 * target.c (target_command): Add command for selecting a target
5011 type and calling its open routine. This is used for initiating
5012 communication with a particular target, in a generic way.
5014 * tm-i960.h: Update for modern gdb. Remove semicolons from
5015 various macros. Handle reading struct return convention, and
5016 error-out attempts to return structs with the "return" command.
5017 Be sure gdb doesn't think we know how to call functions in the
5020 * i960-tdep.c: Rename FRAME_CHAIN_VALID and FRAME_FIND_SAVED_REGS
5021 to i960_xxx in lower case.
5022 (arg_address): Circumvent errors due to LOC_ARG_BLOCK
5023 not being defined yet.
5025 * remote.c (remote_open): Call start_remote to initialize
5026 wait_for_inferior during open.
5027 (remote_xfer_inferior_memory): Return length written rather
5030 * remote-vx.c (target_command -> vx_open): Use new generic
5032 * remote-eb.c, inftarg.c, exec.c: ditto.
5034 * infrun.c: Fix comments.
5035 (attach_program -> child_open): Use new generic target command.
5036 (wait_for_inferior): Clear saved register values before target_wait,
5037 so target_wait can set some of them if convenient.
5039 * infptrace.c (fetch_inferior_registers, store_inferior_registers):
5040 Return success indicator, not void.
5041 (child_xfer_memory): Avoid fetching initial word if we'll
5042 overwrite it anyway.
5044 * infcmd.c (attach_command): Use new generic target open routine.
5045 (_initialize_infcmd): Update doc on attach and detach commands.
5046 (do_registers_info): Merge in a byte-order problem as a FIXME
5049 * findvar.c (find_saved_register): Avoid problem in current frame.
5050 (read_relative_register): Ditto.
5051 (write_register): Convert byte order on the way out.
5053 * exec.c (file_command): Add.
5054 (add_to_section_table, exec_command): Use new bfd_map_over_sections.
5055 (xfer_memory): Common function between core_xfer_memory and
5057 (exec_xfer_memory): Use it.
5059 * pn-opcode.h: Document that a "PN" is a Gould PowerNode.
5061 * breakpoint.c, breakpoint.h, symtab.h, value.h, frame.h, utils.c,
5062 valops.c, stack.c, target.c, sparc-xdep.c, source.c, printcmd.c,
5063 infcmd.c, i960-pinsn.c, eval.c, defs.h: lint and gcc -Wall.
5065 Sun Dec 2 16:45:06 1990 John Gilmore (gnu at cygnus.com)
5067 Merge Intel 960 port of gdb, continuing...
5069 * dbxread.c (partial_symbol_file_open, partial_symbol_file_read,
5070 symbol_file_command): Pass from_tty arg to hush 'em up.
5072 * coffread.c (symbol_file_command): Avoid output if from_tty != 1.
5073 Add magic numbers for 960 COFF format.
5075 Fri Nov 30 09:18:20 1990 John Gilmore (gnu at cygnus.com)
5077 Merge Intel 960 port of gdb, from Intel "1.2" release.
5079 CHANGE_LOG entries from their port, which was based on
5082 Thu Sep 6 11:02:22 PDT 1990
5083 Remove temp file if download is interrupted.
5085 Wed Aug 1 09:08:33 PDT 1990
5086 Now uses binary protocol to talk to NINDY.
5087 Old hex protocol (NINDY 2.13 and older) supported with -O switch.
5088 Times out after 5 seconds when trying to talk to NINDY.
5090 Tue May 29 12:54:49 PDT 1990
5091 Added variable baud rate (-b switch).
5092 Source code reorganization.
5094 Thu Apr 26 11:09:55 PDT 1990
5095 More cleanup of batch mode; specifically, execute "-s", "-e", and
5096 "-se" switches as soon as they are encountered on the invocation line.
5098 Fri Apr 20 13:47:15 PDT 1990
5101 Thu Apr 19 09:54:28 PDT 1990
5102 Add 'reset' command.
5104 Wed Apr 18 09:48:07 PDT 1990
5105 After opening remote tty, wait for 1 second to go by without input
5106 from it before trying to talk to NINDY (fixes problems with the
5107 Heurikon HK80/V960E).
5109 Mon Apr 4 16:33:05 PDT 1990
5110 Some output was not being suppressed in 'batch' mode.
5112 Thu Mar 22 15:31:11 PST 1990
5113 Ask user if old symbol table should be deleted when new file is
5116 Allow user to run a program downloaded before gdb960 was brought up.
5118 Correct "exec-file" help message for i80960 context.
5120 Correct bug in calculating user space address: could occasionally
5121 corrupt user program.
5123 Make sure to zero low-order bits in rip's because of bug in 960CA
5124 A-step part: could cause operation faults when "next"ing across
5127 Correct bug that made it impossible to get source line numbers for
5128 code loaded at addresses higher than 0x7fffffff.
5130 Wed Jan 10 12:43:22 PST 1990
5131 Open remote tty for exclusive use.
5133 Fri Jan 5 12:14:42 PST 1990
5134 Correct disassembly (CA manual was right after all):
5135 opcode for sysctl is 0x659
5137 Mon Oct 23 12:03:04 PDT 1989
5138 Use G960BASE and G960BIN environment variables to find 'sx' utility.
5140 Mon Oct 16 14:15:09 PDT 1989
5141 "sfr0"-"sfr31" should have been named "sf0"-"sf31"
5143 Mon Oct 2 15:56:31 PDT 1989
5145 Added 960CA disassembly support.
5147 To simplify maintenance:
5148 - eliminated use of symblic links on pinsn.c: use i960-pinsn.c
5150 - eliminated opcode.h: incorporates tables into i960-pinsn.c
5151 - moved 960-specific routines from i960-pinsn.c to i960-md.c
5152 - made disassembly interface identical to that in gdmp960.
5156 Wed Nov 28 21:32:48 1990 John Gilmore (gnu at cygint)
5158 * target.h: Allow targets to stack. Add target_has_memory,
5159 _registers, etc. Restructure memory access and "info files"
5160 to walk the target stack.
5161 * exec.c, core.c, inftarg.c, remote.c, remote-vx.c, remote-eb.c,
5162 target.c: Change tables to match target.h.
5163 * inflow.c (child_mourn_inferior): pop child_ops.
5164 (generic_mourn_inferior): Use new has_stack flag.
5165 * infptrace.c (child_xfer_memory): New memory regime.
5166 * inftarg.c (child_files_info): New "info files" regime.
5167 * remote-eb.c: New memory regime, new info files.
5168 * remote-vx.c: New memory regime, new info files. Now use
5169 separate targets for VxWorks attachment to machine, and
5170 actually running a process under VxWorks, since one has
5171 stack & execution & regs and the other doesn't.
5172 * remote.c: New memory regime, new info files.
5173 * sparc-xdep.c (fetch_core-registers): New memory regime.
5174 * target.c: New routines and support for stacked targets,
5175 new memory regime, new info files regime.
5178 Generalize section handling for an arbitrary number of sections,
5179 including use of the new BFD (binary file) library.
5180 * gdbcore.h: Add struct section_table.
5181 * exec.c (build_section_table): Iterate all sections and
5182 record what gdb needs to know about them.
5183 (exec_command): Use it.
5184 (exec_xfer_memory): Use the table.
5185 (exec_files_info): Print the table.
5186 * core.c (core_file_command, core_xfer_memory, core_files_info):
5188 * source.c (find_source_lines): Use bfd_get_mtime.
5189 * dbxread.c: Quick changes to make it compile with new BFD.
5190 * utils.c (error): Avoid using bfd_error in generic routines.
5192 * core.c (core_fetch_registers): Get from the ".regs" section of
5194 * sparc-xdep.c (fetch_core_registers): Use the .regs info.
5196 * inferior.h (attach_flag): Export.
5197 * infcmd.c (run_command): use new target_create_inferior.
5198 * infrun.c (child_create_inferior): Don't return result.
5199 * Makefile.dist (VERSION): 3.91.4.
5201 Fri Nov 23 28:15:38 1990 John Gilmore (gnu at cygint)
5203 * breakpoint.c (bpstat_num): Handle breakpoints which have
5204 since been deleted, such as temporary breakpoints.
5205 infcmd.c (program_info): ditto.
5207 * core.c (core_file_command): Display the frame where the core
5212 * remote-vx.c (target_command): Merge in target command from
5213 targ-vx.c. A few other cleanups.
5215 * TODO, Projects: Lots more stuff to do...
5217 Fri Nov 23 18:15:38 1990 John Gilmore (gnu at cygint)
5219 Massive changes to wall off the remote-debugging interface
5220 behind a function vector. The port to handle VxWorks targets
5221 is also part of this.
5223 All files: Replace references to renamed functions,
5224 remove references to remote_debugging, remove references to
5225 have_include_file, have_core_file in favor of target_has_stack,
5226 target_has_memory, etc.
5228 * Modularize the breakpoint interface.
5229 breakpoint.h (BREAKPOINT_MAX): New define sets max length of
5230 a breakpoint instruction.
5231 breakpoint.c: struct breakpoint's shadow_contents now sized as
5233 (insert_breakpoints): Vector to target to install breakpoints.
5234 (remove_breakpoints): Vector to target here too.
5235 Remove REMOTE_SA_SPARC kludges and other remote_debugging.
5236 sparc-tdep.c (single_step): Use new breakpoint interface for
5237 the single-step breakpoints.
5238 mem-break.c (memory_insert_breakpoint, memory_remove_breakpoint):
5239 New file, contains routines to insert and remove breakpoints by
5240 reading out the old contents and later replacing them. This is
5241 how ptrace breakpoints work, and many remote systems as well.
5243 * tm-vxworks68.h: New config file, overrides a few things for
5244 Wind River's preferences.
5246 * target.h: New file, for transfer vector used to talk to the
5247 inferior (child, attached, core, exec, remote, etc). All accesses
5248 to the thing being debugged should come through these vectors.
5249 target.c: New file, routines to handle transfer vector.
5250 (various files): Add transfer vectors XXX_ops for the various
5251 targets and pseudo-targets (core files, etc) we support.
5253 * breakpoint.c (bpstat_stop_status): Further explorations of
5254 watchpoints and why things don't work all the time.
5255 (bpstat_alloc): New fn to allocate a bpstat and chain it.
5257 * config.gdb: Only add "source ${srcdir}/.gdbinit" to
5258 the local gdbinit if it doesn't already have it.
5260 * core.c (core_ops): add and install.
5261 Allow core debugging without exec file.
5263 * dbxread.c (free_and_init_header_files): Merge two fns.
5264 (end_symtab): Free named symbol table when a new version comes in.
5265 (read_dbx_symtab): Relocate all kinds of symbols with base
5266 address. First step toward handling different text, data, bss
5268 (add_file_addr_command): Renamed add_file_command.
5269 (add_file_command): Vector to remote handler.
5270 Add "load" as an alias for "add-file" command.
5272 * defs.h: Allow "volatile" to be used in non-ANSI; use it for
5273 non-returning functions.
5275 * exec.c: Add exec_ops, and push it as a target when an exec
5278 * infcmd.c (run_command): Pass executable file name and arg list
5279 separately when starting an inferior. Permit "run" when no exec
5280 file is specified, for VxWorks.
5281 (detach_command): Move to child_detach in inftarg.c.
5283 * inftarg.c: New file. Unix-child-specific routines, and the
5284 child_ops structure.
5286 * inferior.h (registers): Export "registers" as the way for
5287 target dependent register handlers to find gdb's local copy of
5288 the registers. Rename "stop_after_attach" to "stop_soon_quietly"
5289 since it is now used by places that want wait_for_inferior to
5290 handle the grunge but want to see every trap from the inferior.
5292 * inflow.c (create_inferior): Pull out, and merge into infrun.c.
5293 Eliminate remote_debugging hooks in terminal handling.
5295 * infrun.c: Replace start_inferior with child_create_inferior.
5296 Move all the hair of Unix shells and ptrace idiosyncracies into
5297 child_create_inferior, so remote handlers don't have to deal.
5298 Remove running_in_shell. Rename stop_after_attach to
5299 stop_soon_quietly, and use it in a few other places where we want
5300 to just call wait_for_inferior and get control back on the first
5301 trap. trap_expected now never takes a value > 1.
5302 (init_wait_for_inferior): Initialize static vars when a new
5305 main.c (gdbinit): Add new hook for .gdbinit file name, let
5306 it be overridden by config files as GDBINIT_FILENAME.
5307 (DEFAULT_PROMPT): Add new hook for overriding (gdb) prompt.
5308 Both of these are used for VxWorks gdb.
5310 mcheck.c: rename include file "gmalloc.c" to avoid problems
5311 with system include file "malloc.c".
5313 param-no-tm.h: New include file, same as param.h but does not
5314 include the default "tm.h" file. This is used in files where
5315 the target is known, e.g. remote-eb.c or sparc-xdep.c.
5317 param.h: Now just a shell that includes tm.h and param-no-tm.h.
5319 remote-vx.c: New file, VxWorks remote debugging support. Uses
5320 RPC routines that are shared with the target system, in directory
5323 remote.c: Vectorize remote interface.
5325 source.c: Globalize source_path, and make an alias "l" for "list"
5326 since we now have the "load" command.
5328 sparc-xdep.c: Use new param-no-tm.h.
5330 symmisc.c (free_named_symtab): Add new function from Wind River.
5331 However, ifdef it out for now while we think about what it should
5334 tm-sun3.h, xm-sparc.h, xm-sun3.h, xm-symmetry.h: Move
5336 the xm- file, and change its name to CHILD_PREPARE_TO_STORE, since
5337 non-Unix-children handle this with their own code in the target
5340 Makefile.dist: Roll version to 3.92.3. Add vx-share stuff to
5341 source and target lists. Add vx-share to default list of include
5342 directories. Add new files to src and target lists: mem-break,
5343 target, inftarg, remote-eb, remote-vx, targ-vx. Be sure the
5344 ${srcdir} versions of munch and createtags are used.
5346 * valops.c (find_function_addr): Split out of call_function.
5347 (call_function_by_hand): Rename call_function; this function
5348 calls functions in the target by laboriously patching the target
5349 word-by-word with the right stack, args, regs, etc.
5352 Mon Nov 5 17:29:10 1990 John Gilmore (gnu at cygint)
5354 Handle AMD 29000 a bit better.
5356 * remote-eb.c (readchar): Mask received char log to make it readable.
5357 (remote_start): Pass arguments down to executing program.
5358 Make startaddr unsigned.
5359 infrun.c (start_inferior): Accept args, pass them to
5361 infcmd.c (run_command): Pass args down to start_inferior.
5363 * tconfig/am29k-aout, tconfig/am29k-coff: New files specifying
5364 the target object file format.
5365 tm-29k.h: Pay heed to COFF_ENCAPSULATE.
5367 * am29k-pinsn.c (print_insn): Print 0x on hex numbers in disassembly.
5368 am29k-tdep.c (examine_prologue): Better checking of function prefixes.
5370 Sun Oct 7 18:20:45 1990 John Gilmore (gnu at cygint)
5372 * Makefile.dist (VERSION): Roll version to 3.91.9 and freeze.
5373 * TODO: We did a few things, we have more to do though.
5375 * xm-sparc.h (CLEAR_DEFERRED_STORES): Define.
5376 * inflow.c (inferior_died): Clear deferred stores.
5378 * Debug problems with dummy frames and calls to the inferior.

5380 * sparc-tdep.c (do_restore_insn): Simplify.
5381 (sparc_frame_find_saved_regs): Simplify and fix what we find.
5382 (sparc_push_dummy_frame): Simplify and fix what we push.
5383 (sparc_pop_frame): Slightly more hair here, deciding whether
5384 we are restoring a saved PC or returning to a return address in %i7.
5385 * sparc-xdep.c (read_inferior_registers): Debug if valid reg is read.
5387 * utils.c (xmalloc, xrealloc): Return type depends on __STDC__.
5388 * symtab.h (xmalloc): ditto, for obstack_chunk_alloc.
5389 * obstack.h (chunkfun): ditto.
5390 * defs.h (xmalloc, xrealloc): ditto
5392 * utils.c (quit): Grab the terminal from the child if necessary.
5394 * inflow.c (term_status_command): Rename to term_info, change
5397 * sparc-pinsn.c (print_insn): Disassembly prefers real instructions.
5398 (is_delayed_branch): Speed up.
5399 * sparc-opcode.h: Add ALIAS bit to aliases. Fix up opcode tables.
5400 Still missing some float ops, and needs testing.
5402 * Support for input and output radixes other than base 10
5403 * defs.h (input_radix, output_radix): Declare.
5404 * expread.y (yyparse, parse_number): Handle changes of input
5405 radix, and ambiguous names-or-numbers in radixes >10.
5406 * printcmd.c (print_scalar_formatted): Print formatted hex
5407 numbers in varying column widths.
5408 * valprint.c (val_print): Use output_format to print scalar ints.
5409 (set_input_radix, set_output_radix, set_radix): Create.
5410 (set_output_radix): Set output_format from output_radix.
5411 (_initialize_valprint): add `set radix' but leave the others off.
5413 * main.c (execute_command): Let stupid questions be turned off.
5414 (_initialize_main): Handle "set stupidity", etc.
5416 * main.c, inflow.c, inferior.h, frame.h, command.c, defs.h,
5417 sparc-pinsn.c, sparc-xdep.c, value.h, valops.c, values.c: Lint.
5419 Tue Oct 2 11:20:02 1990 John Gilmore (gnu at cygint)
5421 * TODO, Makefile.dist, ChangeLog: Freeze for 3.91.8 release.
5422 bfd stuff is still screwed up, but with some manual work, it
5425 * breakpoint.c (bpstat_do_actions): Start over if a command
5426 proceeds the inferior, since the inferior will have stopped and
5427 will need to have its new stop-actions taken care of.
5429 * dbxread.c (read_struct_type): Expression gives Sun3 4.0.3
5430 compiler fits, simplify it.
5432 * gdb.texinfo (directory command): Doc new dir command.
5433 source.c (directory_command): "dir" now puts things on the front
5434 of the path, moves dups up front, and handles multiple names
5435 on the command line, inserting each one in order. It also
5436 blows away cached line and full_filename info.
5438 * stack.c (backtrace_command): Skip "more stack frames follow"
5441 * Change #ifndef HAVE_VPRINTF to #define MISSING_VPRINTF in
5442 xm-convex.h, xm-hp300bsd.h, xm-isi.h, xm-merlin.h, xm-news.h,
5443 xm-np1.h, xm-pn.h, xm-pyr.h, xm-symmetry.h, xm-umax.h, xm-vax.h.
5444 The only odd one was Gould NP1, which had defined vprintf to
5447 * Merge Ted Goldstein <tedg@Eng.sun.com>'s changes for epoch.
5448 printcmd.c (print_command_1): Pass 'inspect' flag down as a global
5449 variable, inspect_it.
5450 valprint.c (print_string, val_print): Use the global inspect_it
5451 to indicate whether to print in Epoch style or normal style.
5453 Mon Oct 1 23:55:26 1990 John Gilmore (gnu at cygint)
5455 * printcmd.c (call_command): add an alias for the "print" command
5456 which runs expressions and doesn't print the result if void.
5457 (print_command_1): implement it.
5459 * command.c: Remove #if 0'd code. Initialize all the fields
5460 in add_cmd (). Rename do_nothing_command to
5461 not_just_help_class_command, and make it externally visible.
5462 command.h: add user_commands to struct.
5463 * main.c (define_command): Don't overload c->function with a char
5464 string as well as a function pointer.
5466 * eval.c (evaluate_subexp): Reinstall tiemann changes to
5467 calling convention of value_struct_elt () that got dropped in
5470 * tm-sparc.h (FRAME_FIND_SAVED_REGS): move to sparc-xdep.c.
5471 sparc-tdep.c (sparc_frame_find_saved_regs): ditto.
5473 * tm-sparc.h (POP_FRAME): replace some constants with defines.
5475 * sparc-xdep.c (store_inferior_registers): defer stores to regs
5476 until a good time (e.g. when we are about to run the child),
5477 saving ptrace calls.
5478 * infrun.c (proceed): handle DO_DEFERRED_STORES.
5479 * tm-sparc.h: define DO_DEFERRED_STORES.
5481 * sparc-xdep.c (store_inferior_registers): when storing float
5482 registers, don't store stack regs too. When storing the SP,
5483 however, DO store the stack regs too. This fixes a bug in which
5484 the dummy frame is not recognized when a call_function finishes,
5485 because its frame pointer (in the stack regs) was never
5487 (read_inferior_registers): Mark WIM and TBR and FPS and CPS valid
5488 even though we don't know how to read them from an inferior.
5489 valops.c (call_function): Comment about storing SP.
5491 * infrun.c (save_inferior_status): Save away the original bpstat
5492 chain so it can be restored later. Install the copied version for
5493 use by whoever saved the status. It will be blow away by
5494 restore_inferior_status, and the original chain restored. This is
5495 important for people who have pointers into the original.
5497 * breakpoint.c, command.h, copying.awk, dbxread.c, defs.h,
5498 findvar.c, frame.h, obstack.h, obstack.c, inflow.c, value.h,
5499 main.c, printcmd.c, sparc-tdep.c, symtab.c, valprint.c: lint
5502 Fri Sep 28 20:32:46 1990 John Gilmore (gnu at cygnus.com)
5504 * Makefile.dist: Roll version to 3.91.8. Add bfd.h and bfdconfig.h
5505 temporarily to the makefile. Add am29k-opcode.h and WHATS.NEW.
5506 Add stuff.c and kdb-start.c to the OTHERS list for tar files.
5508 Fri Sep 28 19:12:12 1990 John Gilmore (gnu at cygint)
5510 * Merge Mike Tiemann's multiple inheritance changes from Sun.
5511 Store the baseclasses in a type struct starting from array element
5512 0 rather than from the unusual array element 1.
5514 dbxread.c: the above.
5515 (virtual_context): Add
5516 Read new debug information about which virtual function table
5517 a virtual function is from, and store it in fn_field.fcontext.
5519 symtab.h: Add fcontextt. Fix baseclass indices. Typo in
5520 TYPE_FN_FIELD_STATIC_P.
5522 symtab.c: the above.
5523 valops.c: the above. Handle pointer casts of object *'s.
5524 (search_struct_method): Add.
5525 (value_struct_elt): First arg is now a pointer to a value, and is
5528 valprint.c: the above.
5529 values.c (value_virtual_fn_field): Add type arg. Handle
5530 offsetting to the proper object when calling virtual fns.
5532 (baseclass_addr): Add valuep arg.
5534 * README: Document the current state of BFD config (missing).
5535 * TODO, ChangeLog, Makefile.dist: Roll version.
5536 * WHATS.NEW: Add summary of changes since 3.5.
5538 Thu Sep 27 16:23:12 1990 John Gilmore (gnu at cygint)
5540 * dbxread.c (read_struct_type): Clear bit vectors whenever
5542 symtab.c (B_CLRALL): define.
5544 * tm-sparc.h (STORE_RETURN_VALUE): Avoid clobbering types by
5545 using == rather than =. Huh... This fixes the dreaded problem
5546 wherein builtin_type_int becomes TYPE_CODE_FLT.
5548 * core.c (info_files): Show the inferior pid.
5550 * config.gdb: Avoid putting "dir" command into .gdbinit. GDB
5551 already knows how to look in the source directory.
5553 * Remove psymtab hair from many places. Remove duplicated code
5554 for searching symbol tables. Hide psymtabs from most places.
5555 Make it fast to get from a psymtab to its symtab.
5557 blockframe.c (blockvector_for_pc): Remove psymtab hair.
5558 coffread.c (psymtab_to_symtab): Rename to psymtab_to_symtab2.
5559 mipsread.c (psymtab_to_symtab): Rename to psymtab_to_symtab2.
5560 dbxread.c: export psymtab_to_symtab, make it work if called N times.
5561 (psymtab_to_symtab): Rename to psymtab_to_symtab2. Initialize
5562 new symtab completely. New psymtabs get symtab pointer
5563 initialized to zero. Remove MI warning printf.
5564 symtab.h: Comments. Add psymtab to symtab pointer.
5565 (PSYMTAB_TO_SYMTAB): New macro.
5566 symtab.c: use PSYMTAB_TO_SYMTAB. Add psymtab_to_symtab and export it.
5567 source.c: use PSYMTAB_TO_SYMTAB. Remove symtab version and
5569 stack.c (backtrace_command): Avoid pre-pass to read symbols, if
5571 (print_frame_info): Avoid special-casing symbols that have not yet
5574 * source.c (open_source_file): Quick path if we have already
5575 located the source file by its full name.
5577 * symtab.c (lookup_symbol): Use find_pc_symtab rather than
5578 find_pc_psymtab. When a name is found in the misc function
5579 vector, search the symbol table for its mangled name, not the
5580 name that the user typed.
5582 * bfd.h: Fix missing comment terminators, make #endifs match.
5584 * valarith.c (value_less): Handle unsigned int comparisons.
5585 Add FIXME about pointer compares, which assume host and target
5586 pointers are the same.
5588 * command.c (do_nothing_command): lint
5589 dbxread.c: lint. Remove sort_syms. Document C++ visibility info,
5590 fix comments on debug symbol format for visibility. Actually set
5591 visibility of symbols.
5592 main.c (echo_command): lint; use <readline/history.h>.
5593 tm-sparc.h (FRAME_FIND_SAVED_REGS): lint
5594 obstack.h (_obstack_blank): Rearrange pointer math to avoid
5595 pointing past end of allocated memory; saber complains.
5596 obstack.h: Declare the external functions that we use.
5597 valarith.h: use <string.h>
5598 solib.c (solib_add): lint.
5600 Fri Sep 21 17:05:19 1990 John Gilmore (gnu at cygint)
5602 * main.c (initialize_main): Default info_verbose to off, now that
5603 symbol reading is fast.
5604 (quit_command): Avoid clobbering exec_bfd while quitting.
5606 * Initial BFD (binary file diddling library) merger:
5607 coffread.c: Change AOUTHDR to struct exe_hdr.
5609 core.c: initialize initialized data at compile time.
5610 (core_file_command): Move from coredep.c, convert to bfd.
5611 (xfer_core_file): Convert to bfd.
5612 exec.c (exec_file_command): use bfd routines.
5614 mips-tdep.c: Remove exec_file_command and friends.
5617 * coredep.c: (fetch_core_registers) Convert core_file_command to
5618 fetch_core_registers.
5619 mips-xdep.c, sparc-xdep.c, sun3-xdep.c: ditto.
5621 * utils.c: (error): Bogus crap, FIXME, to print bfd errors.
5622 (my_bfd_read): More bogosity, which I don't think we call.
5623 (program_name): Remove this atrocity asap!
5625 Wed Sep 19 13:36:41 1990 John Gilmore (gnu at cygint)
5628 values.c: allocate_repeat_value was not clearing the
5629 optimized_out field.
5630 (value_static_field): minor stylistic fix (wrong macro was used).
5631 valops.c (value_struct_elt_for_address): didn't work for C++
5634 * signame.c (_initialize_signame): Initialize signal names once.
5636 * breakpoint.h, command.c, copying.awk, defs.h, environ.c,
5637 exec.c, frame.h, infcmd.c, inferior.h, main.c, munch, sun3-xdep.c,
5638 symtab.h, tm-29k.h, valprint.c, value.h, values.c: Lint.
5640 * remote-eb.c: Support user-settable baud rates on the serial port.
5642 * tm-sun3.h (PREPARE_TO_STORE): fix typo.
5644 Fri Sep 14 13:28:29 1990 John Gilmore (gnu at cygint)
5646 * tconfig/sun3os4: Remove warning about native assembler,
5647 since it also occurs in the xconfig file.
5649 * findvar.c (registers): Allocate some slop after `registers'
5650 to prevent stray accesses from trashing the next variable.
5652 * tm-68k.h (REGISTER_BYTES): Allocate the right number of bytes
5653 on the sun-3, by changing the #ifdef from `sun3' (which is not
5654 defined by cc) to `sun'. Symptom was trashed builtin_type_XXX
5655 vars, which happened to follow `registers' in the executable.
5657 * readline/history.c (history_search): Heed gcc-2's advice
5658 and parenthesize && inside ||).
5660 * am29k-opcode.h, am29k-pinsn.c, am29k-tdep.c, remote-eb.c,
5661 tm-29k.c: Insert FSF copyright headers.
5663 * remote-eb.c: Better comments.
5665 * Makefile.dist: Update to 3.91.6.
5666 * TODO: note PREPARE_TO_STORE problem.
5668 Thu Sep 13 09:52:33 1990 Jim Kingdon (kingdon at cygint)
5670 * stack.c (frame_info): Only use FRAME_FIND_SAVED_REGS if defined.
5672 * remote.c: Wrap the whole file in #if !defined (SPECIAL_REMOTE).
5674 * infrun.c (wait_for_inferior, at end): Don't set up
5675 prev_* if the inferior no longer exists.
5677 * inferior.h (CALL_DUMMY_LOCATION): New macro, to replace
5678 CANNOT_EXECUTE_STACK.
5679 valops.c (call_function): Use it.
5681 * tm-convex.h: Add CALL_DUMMY_LENGTH for use by PC_IN_CALL_DUMMY.
5683 * inferior.h (PC_IN_CALL_DUMMY): New macro.
5684 infrun.c (wait_for_inferior, 2 places): Use it.
5686 * values.c (value_being_returned): Only use
5687 EXTRACT_STRUCT_VALUE_ADDRESS if defined.
5689 * Move PREPARE_TO_STORE from xm-sun3.h to tm-sun3.h to do the
5690 right thing for remote-eb.c.
5692 * sun3-xdep.c: Remove extraneous call to remote_store_registers.
5693 * sun386-xdep.c, hp300hpux-xdep.c, sparc-xdep.c: Ditto.
5695 * blockframe.c: Put get_frame_saved_regs inside #if !defined
5696 (FRAME_FIND_SAVED_REGS).
5698 * findvar.c ({fetch,store}_registers): Check for
5699 REMOTE_{FETCH_STORE}_REGISTER macro.
5701 * findvar.c (get_saved_register): Add argument lval and
5702 change meaning of argument addr.
5703 findvar.c: Change calls to get_saved_register to reflect
5704 new calling convention.
5705 valops.c (value_assign): Use get_saved_register instead of
5706 find_saved_register.
5708 Sun Sep 2 12:40:20 1990 Jim Kingdon (kingdon at cygint.cygnus.com)
5710 * coffread.c (read_one_sym): Make temp_aux an AUXENT, not
5711 an (uninitialized) pointer to one. Use "&" when passing it
5714 Fri Aug 31 22:57:54 1990 Jim Kingdon (kingdon at cygint.cygnus.com)
5716 * coffread.c (getfilename): Use DGUX x_offset and x_name if
5719 * coffread.c (symbol_file_command): Put semicolon after
5721 Put safe_to_init_tdesc_context in #if defined (TDESC).
5722 Put #ifdef TDESCs in 1st column for non-ANSI cpp's.
5723 coffread.c: #include <sys/stat.h>.
5724 (read_coff_symtab): Typo: in_source_files -> in_source_file.
5725 Add missing ')' in check for "lc%" and friends. Remove
5727 Declare read_one_sym() at top of file.
5728 (read_file_hdr): Put in extra #ifdefs so MC68MAGIC and
5729 MC68WRMAGIC can have the same value without causing a duplicate
5732 Thu Sep 13 15:55:36 1990 John Gilmore (gnu at cygint)
5734 * Allow a Makefile to be built without building the
5735 tm and xm file links that screw up builds in subdirectories.
5736 This is done with `config.gdb none', then you can do things
5737 like `make gdb.tar.Z'.
5738 * tconfig/none: Config file for no target system
5739 * xconfig/none: Config file for no host system
5740 * config.gdb: If no TM or XM files are called out by the
5741 host or target file, don't make links for them.
5743 * cplus-dem.c: Add documentation.
5745 * dbxread.c (read_ofile_symtab): Turn a fatal error into a
5746 simple error, so the user's gdb doesn't crash due to some object
5747 file problem (e.g. somebody is rebuilding the file out from under
5750 * printcmd.c (print_address_symbolic): demangle the symbol.
5752 * Makefile.dist (OTHERS): Remove tdesc-lib because it has
5753 Motorola copyrights in it. Make "make gdb.tar.Z" work.
5754 (alldeps.mak): sort and uniq all results from this; duplicates
5755 hose gdb.tar.Z link building. Remove RCS files from
5756 tconfig and xconfig. Add config files for sun386. Add
5757 a few odd files to OTHERS and HFILES.
5759 Mon Sep 10 21:20:24 1990 John Gilmore (gnu at cygint)
5761 * Makefile.dist: Pull solib.c to tconfig/sun?os4.
5762 Roll version number to 3.91.5. Make lint work in bindir.
5764 * README: Document cross-debugging and new file structure.
5766 * blockframe.c: Lint. Include "value.h" to declare read_register.
5767 (find_pc_partial_function): remove duplicate line.
5769 * command.h: Lint. Declare error_no_arg and dont_repeat.
5771 * tm-news.h: Remove inadvertently duplicated stuff.
5773 * mipsread.c: Remove cache_pc_function stuff, now done cleanly.
5774 Clean up usage of misc_function_type. Declare some CORE_ADDRs.
5776 * config.gdb: Allow `config.gdb host target' form. Clean
5777 up previous change that printed bogus messages when you just said
5780 * core.c: #include "command.h" for lint.
5783 * main.c: Remove some casts of enums. Lint.
5790 * printcmd.c (initialize_printcmd): Fix thinko in inspect cmd.
5792 * sparc-tdep.c (isannulled): Take instruction as parameter, don't
5793 read it from memory. This will allow us to save ptrace calls
5794 eventually. Changed caller single_step too.
5796 * sparc-xdep.c (fetch_inferior_registers): Avoid reading regs
5797 that we aren't going to use, saving many ptrace calls, especially
5798 when watchpointing or single stepping. Use some #define's for
5800 (store_inferior_registers): Ditto.
5801 (core_file_command): Use some #define's for constants.
5803 * tm-sparc.h: Add #define's for some register numbers, so we
5804 can eliminate the use of random constants in sparc-xdep.c.
5806 * stack.c (frame_command, print_frame_info, up_command,
5807 down_command) Remove frame_changed, since it
5808 causes a bug and doesn't seem to do anything useful. In some
5809 places it was used as a flag, in others as a stack level (?).
5811 * utils.c: Use MISSING_VPRINTF rather than HAVE_VPRINTF, so the
5812 default is to use the portable (vprintf) version rather than the
5814 * xm-news.h (MISSING_VPRINTF): Add.
5816 * valprint.c (val_print): Demangle fancy vtbl printouts. Lint.
5818 Sat Sep 8 00:24:12 1990 John Gilmore (gnu at cygint)
5820 * Remove stuff that forces -Bstatic linking of gdb, and warnings
5821 about linking debugged programs -Bstatic in the sun?os4 config
5822 files in tconfig and xconfig subdirectories.
5824 * main.c (main): Remove unreached exit(0) now that we exit
5827 * Create TODO file for online bug list. There are too many
5828 "little" bugs to keep track of on paper.
5830 * Change Projects file to refer to bug-gdb@cygnus.com
5831 rather than kingdon@ai.
5833 Fri Sep 7 23:35:15 1990 John Gilmore (gnu at cygint)
5835 * Makefile.dist (VERSION): 3.91.4 now.
5837 * symtab.c (init_misc_bunches): Rename from init_misc_functions.
5838 (condense_misc_bunches): Add sanity check that misc_count is
5839 the same as the number of symbols in the bunch.
5841 * coffread.c: rename init_misc_bunches. Pass an argument
5842 to condense_misc_bunches (a zero).
5844 * dbxread.c (partial_symbol_file_read): Call init_misc_bunches
5845 every time we are called; don't rely on our caller to do it.
5846 (add_file): Remove call to init_misc_bunches.
5848 * mipsread.c: Only warn, don't error, if unknown symbol types.
5849 This keeps an old gdb from falling on its face if it sees newly
5850 extended symbol info. Rename init_misc_bunches.
5852 Fri Sep 7 22:58:15 1990 John Gilmore (gnu at cygint)
5854 * Merge in changes from Per Bothner for DECstations and other
5855 MIPS stuff. The rest is Bothner speaking:
5857 The next message is a merger of Alessando Forin's mips port with
5858 mine. I've tried to use my good if biased judgment to get
5859 the best of both. It *does* need testing.
5861 Some of the changes are general, *not* mips-specific.
5864 Didn't believe in little-endian bit order.
5865 There are still inconsistencies about whether flags
5866 like BITS_BIG_ENDIAN are integer (#if ...) or
5867 boolean (#ifdef ...). I tried to paper over them.
5869 dbxread.c,coffread.c,mipsread.c,symtab.c,symtab.h:
5870 Moved some misc_function code that was common to
5871 {dbx,coff,mips}read.c to symtab.c.
5872 In the process, I think I cleaned things up a bit.
5873 At the same time, moved obsavestring and obconcat to symtab.c.
5876 Removed obsolete condense_addl_misc_bunches (use
5877 condense_misc_bunches(1) instead).
5880 Needed to include <sys/dir>, at least on DECstations.
5882 valops.c, mips-tdep.c, tm-mips.h:
5883 Added PUSH_ARGUMENTS macro to support funny argument-pushing
5884 conventions (when STACK_ALIGN is insufficient).
5885 Needed on mips, where doubles need 8-byte alignment,
5886 but ints only need 4.
5889 Removed cruft that was not being used.
5890 Merged in many fixes (most from Frank Yellin, fy@lucid.com).
5893 Print $ before register-names (I think that makes things a little
5895 Never print two instructions, even if one delays.
5896 Removed hex-disassemble set_cmd. (This is not mips-specific,
5897 so I think the argument is whether it is generally worthwhile or not.
5898 I'm inclined to think not, given how easy it is to
5899 convert between radixes in gdb.)
5902 This is basically Alessando's code.
5903 It doesn't use obstacks; I changed it to use obstacks
5904 in a few minor places where using malloc causes a
5905 memory leak. (Probably, more places could/should be changed.)
5906 I added record_misc_function where it was missing.
5907 In symbol_file_command and add_file_command, I tried
5908 to make the code consistent with more recent versions.
5909 Minor sylistic changes in parse_procedure.
5910 Make a .gdbinfo. psuedo-symbol point back to the real
5911 procedure symbol (using the isym field).
5914 This is basically from my port, but with a lot of details
5915 and a number of routines merged in from Alessando's version.
5916 I basically used my code "raw" backtrace (use heuristics
5917 from the actual code, rather than symbol table info) - though
5918 the idea is Alessandro's. I feel my code is a little cleaner
5919 here, particularly in being a little more flexible, such as being
5920 able to handle gcc-produced code (which it now can).
5921 It also doesn't do frame caching (which is not useful
5922 more recent gdb versions).
5923 I also used my code for push_/pop_dummy, more or less.
5924 I tried to incorporate AF's code for testing sigtramp
5925 while backtracing; I probably got it wrong.
5926 Added mips_print_register, which tries to scrunch as much
5927 information as possible on a screen...
5928 Removed the skip-prologue set_cmd. As with hex-disassemble (see
5929 under mips-pinsn.c), I don't see anything mips-specific here,
5930 and I don't see it being all that useful anyway.
5933 Added a $fp psuedo-reg distinct from $fp (nice for gcc).
5934 Use more register names (rather than hard-cases numbers).
5936 Thu Sep 6 18:33:15 1990 John Gilmore (gnu at cygint)
5938 * Hack up 3.90.11 changes:
5940 * Makefile.dist (depend): parameterize $(GCC).
5941 Add solib.c and solib.o.
5942 (readline): Fix vpath for both absolute or relative SRCDIR.
5944 * blockframe.c: Fix from Schaefer@asc.slb.com for shared libs.
5945 Also, let the part I didn't understand at least compile so
5946 I can test the rest. FIXME.
5948 * dbxread.c: Fix thinko using strcmp.
5949 (init_psymbol_list): declare static.
5950 (partial_symbol_file_open): Comment cleanups better, avoid
5951 cleaning up the string table since the caller will do that.
5952 Move the stat for mod time into symbol_file_command, temporarily.
5953 (There should be a mod time for each symbol file, eventually,
5954 to control its rereading. FIXME.)
5956 * infptrace.c (PT_WRITE_D): use same value as PT_WRITE_I for
5957 SunOS, which gives error for shared libs otherwise. (From
5958 Schaefer, probably FIXME needs work for portability.)
5960 * solib.c: Move #include "param.h" to work.
5961 Lowercase all the Uppercase Letters In the Messages.
5962 (find_solib): Clean up inferior_so_name for debug printouts.
5963 Allow no argument, to mean all shared libraries.
5965 * symmisc.c: include param.h to get CLEAR_SOLIB.
5967 Wed Sep 5 18:00:08 1990 John Gilmore (gnu at cygint)
5969 * Merge in Kingdon's changes from FSF: the diffs from 3.90.9
5970 to 3.90.11. ChangeLog entries below are from this.
5972 Wed Jun 13 09:17:39 1990 Jim Kingdon (kingdon at mole.ai.mit.edu)
5976 * Makefile.dist (HFILES): Add tm-sunos.h.
5978 Tue Jun 12 16:15:26 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5982 * Makefile.dist (gdb.tar.Z): Change linking of config so it works.
5984 Thu Jun 7 16:22:27 EDT 1990 Jay Fenlason (hack@ai.mit.edu)
5986 * sparc-opcode.h Added single-operand version of rett.
5988 Mon Jun 4 18:12:31 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5990 * m-sparc.h (REG_STRUCT_HAS_ADDR, STRUCT_ARG_SYM_GARBAGE):
5991 Put parens around gcc_p in expansion.
5993 Thu May 24 15:44:51 1990 Jim Kingdon (kingdon at mole.ai.mit.edu)
5995 * utils.c (lines_to_list): Return 10 if lines_per_page == 0.
5997 Wed May 23 16:36:04 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5999 * Changes for Sun shared libraries:
6000 blockframe.c (find_pc_partial_function): If a non-text symbol
6001 is found, set *address = pc - FUNCTION_START_OFFSET.
6002 breakpoint.c (insert_breakpoints) [DISABLE_UNSETTABLE_BREAK]:
6003 Disable breakpoints instead of giving an error.
6004 source.c (select_source_symtab): Initialize cs_pst.
6005 symmisc.c: Call CLEAR_SOLIB if defined.
6006 symtab.h: Make text{low,high} CORE_ADDR not int.
6007 (psymtab): New field addr.
6009 dbxread.c: Move DECLARE_FILE_HEADERS outside functions.
6010 (record_misc_function): Give correct type for N_DATA symbols.
6011 (condense_misc_bunches): do "misc_function_count = j" regardless
6013 Take code which is shared between symbol_file_command and
6014 add_file_command and put it into partial_symbol_file_{open,read}.
6015 Split add_file_command into add_file_command and add_file.
6016 Make psymtab_to_symtab read in the string table if the file
6018 Two new parameters to read_dbx_symtab and start_psymtab.
6019 tm-sunos.h: New file.
6021 Tue May 22 17:43:03 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
6023 * infcmd.c: Change cont_command to continue_command and "cont"
6026 Mon May 21 14:41:41 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
6028 * breakpoint.c (enable_breakpoint): Get value of watchpoint.
6030 * defs.h [sparc]: Use <alloca.h> regardless of __GNUC__.
6032 * values.c (USE_STRUCT_CONVENTION): Check for structures of
6033 size 1,2,4,8 rather than size < 8.
6035 * dbxread.c (dbx_lookup_type): Do f->length *= 2 as many times
6036 as necessary, not just once.
6038 * sparc-opcode.h: Add a bunch of new opcodes which Sun as supports.
6040 Thu May 17 15:04:09 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
6042 * {t,x}m-sun386.h, sun386-xdep.c, {x,t}config/sun386
6044 * tm-news.h: Add CALL_DUMMY_*.
6046 * tm-68k.h: Remove duplicate comment at FRAME_FIND_SAVED_REGS.
6048 * config.gdb: In list_host, list_target, use ${i}, not $i.
6050 Tue May 15 21:27:12 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
6052 * source.c (find_source_lines) [BROKEN_LARGE_ALLOCA]: Use xmalloc.
6054 * sparc-opcode.h: Change all store floating-point state register
6055 instructions to have the right match & lose fields.
6057 Sat May 5 12:39:18 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
6059 * Makefile.dist: Move -I${srcdir} to GLOBAL_CFLAGS and pass
6061 config.gdb: If srcdir != ., create readline directory and
6062 copy a makefile into it.
6064 * wait.h, infrun.c: Change WRETCODE to WEXITSTATUS for
6065 consistency with POSIX.
6067 * breakpoint.c (bpstat_stop_status): Disable watchpoint
6068 when we exit its exp_valid_block.
6070 Tue Sep 4 11:46:46 1990 John Gilmore (gnu at cygint)
6072 * Makefile.dist: Bump version to 3.91.3.
6074 * Clean up handling of breakpoint commands (somewhat).
6075 Prompted by Tiemann bug report "cont 10" doesn't work any more.
6077 inferior.h: Add breakpoint_proceeded to inferior status struct
6078 and globals; save it and restore it.
6079 (clear_breakpoint_commands): Cleanup, remove old #define.
6081 infrun.c (clear_proceed_status): Set breakpoint_proceeded.
6082 (save_inferior_status, restore_inferior_status): handle it also.
6083 (proceed): Remove earlier code that set breakpoint_proceeded.
6084 It is now set only in clear_proceed_status.
6085 (clear_proceed_status): Cleanup, use bpstat_clear rather
6086 than clear_breakpoint_commands. No callers need the stop_bpstat
6087 between clear_proceed_status and proceed.
6089 infcmd.c: Add breakpoint_proceeded definition and comment.
6090 (cont_command, jump_command, signal_command): Move call to
6091 clear_proceed_status right next to call to proceed.
6093 breakpoint.c (bpstat_do_actions): Avoid clobbering our
6094 caller's argument while running down the chain of breakpoints.
6095 Use new variable "breakpoint_proceeded" to determine when
6096 a command that it executes moves the inferior past the
6098 (bpstat_clear): Handle NULL argument.
6099 (bpstat_clear_actions): Avoid useless call to
6100 breakpoint_auto_delete.
6101 (delete_breakpoint): Clean up bpstat's that are pointing to
6102 the deleted breakpoint from the stop_bpstat chain.
6103 (breakpoint_auto_delete): Simplify.
6105 * Clean up handling of EOF, error on stdin, etc. This was
6106 prompted by a network problem that caused gdb to go into an
6107 infinite loop filling up its malloc'd memory.
6109 main.c (return_to_top_level): Cleanup: call bpstat_clear_actions,
6110 not clear_breakpoints_commands, which is now gone.
6111 (main): If command_loop returns (e.g. from EOF on stdin), do
6112 a quit_command (looping back to command_loop if quit_command
6113 doesn't really quit).
6114 (command_loop): check result from command_line_input and
6115 exit if it returns NULL, rather than passing the NULL to
6117 (gdb_readline): Free malloc'd result space before returning
6120 * utils.c (query): Handle C-d to mean "yes", just as if the
6121 input was not a terminal. Also avoid infinite loop if EOF
6122 occurs in mid-input-line before newline. This allows
6123 query to be used at EOF on stdin with reasonable results.
6125 * infrun.c (proceed): Set breakpoint_proceeded.
6127 * values.c (value_as_long): Avoid infinite recursion for enums.
6128 (_initialize_values): Fix typo in help msg (kingdon).
6130 * Makefile.dist (RL_LIB): Use RL_LIB_DEP for dependencies,
6131 RL_LIB for linking. This allows -lreadline for linking
6132 and nothing for dependencies, once readline is a real library.
6134 * config.gdb: Jim Kingdon: give useful error message if the
6135 host or target type is not recognized.
6137 * defs.h (alloca): SPARC <alloca.h> does not declare alloca,
6138 it just defines it. Dumb, but deal with it.
6140 * Jim Kingdon suggests:
6141 in xconfig/sun3os4, CFLAGS should be XM_CFLAGS.
6143 Wed Aug 29 18:03:27 1990 John Gilmore (gnu at cygint)
6145 * Makefile.dist (VERSION): Bump version # to 3.91.2.
6147 * Clean up Bothner's changes.
6149 * blockframe.c (clear_pc_function_cache): New function.
6150 * blockframe.c: remake cache_pc_function_* static.
6151 * dbxread.c (symbol_file_command): remove references to
6152 cache_pc_function_* variables.
6153 * dbxread.c (read_struct_type): Use VOFFSET_STATIC.
6154 * printcmd.c: Avoid kludging a global variable (addressprint)
6155 to avoid printing the address of a string twice. Instead,
6156 pass the format letter 's' down low enough that it can be seen
6157 to avoid this problem.
6158 (print_formatted): Pass format arg to value_print.
6159 (restore_addressprint): Remove function.
6160 (do_examine): Avoid hacking addressprint, cleanups and such.
6161 (print_frame_args): Add a comment to a Bothner change.
6162 * symtab.h: define VOFFSET_STATIC and use it instead of "-1".
6163 * symmisc.c (free_all_symtabs): Call clear_pc_function_cache
6164 to wipe out the values cached in blockframe.c.
6165 * symtab.c (find_method): Add comment saying how big you must
6166 allocate to be "big enough". Per being terse again.
6167 * valprint.c (val_print): Handle format letter "s" to print
6168 strings without addresses. Add comment to vtbl printing code
6169 which casts with wild abandon. Rearrange reference-printing
6171 @0xaddr: value (print w/addressprint)
6172 value (print w/~addressprint)
6173 @0xaddr (parameter lists w/addressprint)
6174 or nothing (parameter lists w/o addressprint)
6176 Tue Aug 28 10:47:18 1990 John Gilmore (gnu at cygint)
6178 * Merge more changes from Per Bothner:
6180 Gdb's handling of TYPE_CODE_REF was so counter-C++ (and otherwise
6181 annoying) that I tried to improve it. Here are my suggestions.
6183 These patches all attempt to handle TYPE_CODE_REF (as in C++) better.
6186 Do automatic de-reference when taking the address of a reference.
6188 Don't deref_ref when printing parameter lists.
6190 More attempts at treating refernences properly.
6192 In val_print, if deref_ref==0, don't print dangling " = ".
6194 Add COERCE_REF macro, which de-references an REF.
6196 * Merge changes from Per Bothner:
6198 * Fixed (Sony news)-specific configuration problems.
6199 * Fixed other problems with using vanilla pcc and libc (enum problems;
6200 assumption that vsprintf exists).
6201 * Some major speed-ups (finc_pc_partial_function now caches a match;
6202 parsing avoids duplicate symbol_lookup calls).
6203 * Changed handling of baseclasses (no longer use baseclasses field
6204 of struct type, use the first n_baseclasses fields instead).
6205 * Various minor changes/fixes, most C++-related.
6208 Cache the most previous match from find_pc_partial_function.
6209 (Save both low and high ends of matching function's pc range.)
6210 This speeds up the loop of infrun.c:wait_for_inferior quite
6211 a bit, and makes step/next commands much zippier.
6213 Added an enum->int cast (otherwise, some compilers barf).
6215 No longer set baseclass offset to 0, since multiple
6216 inheritance now mostly works.
6217 Added a number of casts, to shut up compiler warnings
6218 (after stabs where made enums, not ints).
6219 When discarding a symbol table (in symbol_file_command),
6220 must clear the cache introduced in blockframe.c.
6221 Don't convert $vtbl_ptr_type to vtbl any more.
6222 Get rid of TYPE_BASECLASEES and baseclass_vec (see also symtab.h).
6223 Mask off sign bit emitted by g++ for virtual table offset.
6224 Set voffset to -1 (not 1) for static member functions.
6226 Changed parsing/lexing of names to avoid doing symbol lookup twice
6227 (once when lexing to determine symbol class, once for real).
6228 Now only call symbol_lookup once. Fields of 'this' win especially big.
6230 Subpress printing addr twice in the case of 'x/s addr'.
6232 lookup_basetype_type is no longer used.
6233 Add find_methods as recursive helper function to decode_line_1.
6234 This allows multiple inheritance to work.
6235 Also, once one or more matches has been found, do not look in
6236 base-classes. (Baseclass methods would be overridden, anyway.)
6238 Removed baseclasses array in struct type.
6239 Instead of using baseclasses[i], use fields[i-1].
6240 Added virtual_field_bits[i] to indicate if the i'th baseclass is virtual.
6241 Changed sign convention of voffset (previous was inconsistent).
6243 Some macros (CALL_DUMMY and relatives) were missing. Put them back.
6245 Used to assume existence of vsprintf. Re-written to not need it
6246 if HAVE_VPRINTF is undefined.
6248 typecmp was too pessimistic. Made it less so.
6250 Don't print space after address.
6251 If vtable points to a misc symbol (with 0 offset), print it,
6252 since that indicates the actual class of the object.
6253 Changed ype_print_derivation_info to use new inheritance
6254 scheme (without baseclasses vector).
6256 In value_primitive_field, fixed some bugs left over from previous set of fixes.
6257 Also, changes needed because TYPE_BASECLASSES were removed.
6259 REGISTER_U_ADDR didn't work for PC. Rewrote to use an array.
6261 Tue Aug 21 20:08:54 1990 John Gilmore (gnu at cygint)
6264 If there is no path set, and the symbols don't indicate what directory
6265 a file was compiled in, look in the current directory. But either
6266 a path or a known compilation directory will prevent this.
6269 Three independent bug fixes:
6270 * Remove the #if 0 block that breaks some stuff.
6271 * SunOS 4.1 fixed the promoted-parameter-wrong-addr bug in Sun C;
6272 adapt gdb to either SunOS 4.0.* or 4.1.
6273 * MAX_OF_TYPE and MIN_OF_TYPE thinko. By tedg@sun, I think.
6276 Instantiate the class T when looking for methods in it. (Tiemann@sun)
6279 (type_print) Demangle the name being printed.
6280 (type_print_base) Handle botched demangling without coredump (tiemann).
6283 (check_stub_method): Document routine.
6284 (tiemann) fix bug for no-arg functions
6285 Avoid clobbering beyond end of malloc'd storage.
6286 Terminate the argument list properly.
6288 Sat Aug 18 01:29:59 1990 Per Bothner (bothner@cs.wisc.edu)
6290 * Changes merged by John Gilmore:
6293 In breakpoint_1, use new print_address_symbolic instead
6294 of find_pc_partial_function. (This forces use of assembler-level
6295 addresses, and avoids misleading non-mangled source-level names.)
6297 Generalize ansi argument such that -1 means skip arglist totally.
6298 Removed global variable print_ansi_qualifiers (which made
6299 code non-reentrant), in favor of extra explicit arguments
6300 to internal routines.
6302 Add new helper function print_address_symbolic.
6303 Use find_pc_misc_function instead of find_pc_partial_function
6304 (since we want assembler-level symbols here).
6306 Print unknown function as just "f (...)", not "f (...) (...)".
6307 Use new fputs_demangled explicitly.
6309 Fixed a typing violation (problem: value.h cannot be imported
6310 without renaming many variable in this file).
6311 lookup_symbol: If no matching misc_func, look for a C++-mangled name.
6312 decode_line_1: Moved forward some never-reached code.
6313 Made decode_line_2 skip function prologues correctly.
6315 fputs_filtered should not demangle by default.
6316 Add new fputs_demangled to demangle on demand..
6318 Change value_struct_elt to use value_primitive_field (using recursive
6319 utility function search_struct_field). This allows foo.bar to work
6320 for multiple inheritance (so far only for data fields).
6321 Change check_field in the same way (recursive helper function
6322 to support multiple inheritance).
6323 (Note: there are more of these problems that I haven't fixed.
6324 Any code that says TYPE_BASECLASS (t, 1) is probably wrong.)
6325 value_of_this: 'this' symbol name is now just "this", note "$this".
6327 Don't print static members.
6328 Avoid printing "members of <type>" if there are none.
6329 Simplified type_print_derivation_info by merging duplicate code.
6330 Remove useless blank lines in type_print_base (ptype command).
6332 Added declaration of new routine value_primitive_field.
6334 Added value_primitive_field which is generalized version of
6335 value_field that can handle multiple inheritance (non-zero offsets etc).
6336 Re-implemented value_field to call value_primitive_field.
6338 Fri Aug 17 23:33:44 1990 John Gilmore (gnu at cygint)
6340 * infcmd.c -- insert else to avoid 'delete env' coredump when you
6341 delete the whole environment. Karl Berry reported the bug.
6342 * source.c - fix openp to avoid //'s in filenames, which
6343 trigger an Emacs bug causing it to not be able to find files
6344 when running gdb in a window.
6345 * dbxread.c - zap the #if 0 that botches the add-file code.
6346 It seems to work a lot better without all the code commented out.
6348 Fri Jul 20 16:58:46 1990 John Gilmore (gnu at cygnus.com)
6350 * Merge Tiemann's and Ted Goldstein's changes, detailed below,
6353 Tue Jul 17 19:34:33 1990 Ted Goldstein (tedg at golem)
6355 * Makefile - added a ${CFLAGS} to a couple of entries,
6356 added remote-sa.sparc.c
6357 * added remote.sa-sparc.c, a modification of remote.c
6358 which conducts a dialog directly with the SparcStation prom.
6359 * breakpoint.c, infrun.c, sparcdep.c added
6360 remote_insert_breakpoint(), and remote_remove_breakpoint()
6361 to breakpoint.c instead of directly writing breakpoint instructions.
6362 * sparcdep.c on remote_debugging,there is no need
6363 to remove signle step breakpoint instructions.
6364 * main.c added "-epoch" flag and "int epoch_interface" to main.c
6366 * printcmd.c - epoch interface sends lisp expressions to open up
6367 epoch windows on inspection.
6368 * valprint.c - added arrayprint, and addressprint and made adding
6369 format controls easier
6370 * wait.h added a couple of undef's because we were getting
6371 complaints about WSTOPSIG and WTERMSIG begin redefined.
6374 Wed Jul 4 05:27:51 1990 Michael Tiemann (tiemann at masham)
6376 * symtab.c (decode_line_1): Add support for handling method stubs
6377 in the type information.
6379 Tue Jul 3 09:39:18 1990 Michael Tiemann (tiemann at masham)
6381 * values.c (baseclass_addr): Run loop from INDEX+1 to
6382 N_BASECLASSES; otherwise, we can still get into a loop.
6383 @@ This should be restructured to use a cleaner search strategy.
6385 Sun Jul 1 12:28:51 1990 Michael Tiemann (tiemann at masham)
6387 * dbxread.c (define_symbol,read_type): Grok GNU C++'s new
