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

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

140 Wed Nov 13 19:51:11 1991 Steve Chamberlain (sac at cygnus.com)
142 * Makefile.in, xconfig/delta88 made it install a sysV manual page;
143 gdb.z into the right place.
145 Wed Nov 13 16:45:13 1991 John Gilmore (gnu at cygnus.com)
147 Motorola 88000 port without tears, I mean without tdescs.
149 * m88k-tdep.c: Blow away all tdesc stuff.
150 Provide functions for all the frame-related macros in
151 tm-delta88.h. Adopt i960-style EXTRA_FRAME_INFO.
152 (examine_prologue, frame_find_saved_regs, skip_prologue): borrow
153 from i960-tdep.c and adapt to the function prologues on the 88k.
154 (read_next_frame_reg): Borrow from mips-tdep.c.
155 FIXME: frame_locals_address should go away.
157 * tm-delta88.h: Dump all the tdesc stuff.
158 Macros for all frame-related stuff call fns of same name.
159 Remove duplicated definitions. FP_REGNUM becomes same as
162 * xm-88k.h: Eliminate lots of library dependencies, now handled
163 in libiberty. Eliminate KDB nonsupport.
165 * doc/gdbint.texinfo: Add rudiments on frames. FIXME, add more.
168 * stack.c (frame_info): Mark frameless functions.
169 Print locals address (FIXME, remove if same).
170 * blockframe.c: Comment changes, FIXME after.
171 * coffread.c: Even without TDESC, need to zap "@" symbols.
172 Don't register for wierd format names; change the names in BFD.
174 * alloca.c, language.c, tdesc.c: Lint.
175 * tdesc.c, tdesc-lib: FIXME: remove these.
177 Tue Nov 12 19:30:22 1991 John Gilmore (gnu at cygnus.com)
179 * Makefile.in: Add tdesc library support. Fixups to lint,
182 Tue Nov 12 13:43:26 1991 Per Bothner (bothner at cygnus.com)
184 * symtab.c (decode_line_1): Remove spurious call to operator_chars.
186 Allow setting breakpoints on C++ destructors.
187 * valops.c (destructor_name_p): Don't check TYPE_HAS_DESTRUCTOR,
188 since it lies. Rely on callers to catch missing destructors.
189 * symtab.c (decode_line_1): For example (see above), here.
190 * buildsym.c, symtab.h: Remove TYPE_FLAGS_HAS{CON,DE}STRUCTOR
191 flags since they are no longer used.
193 Fixes to support C++ methods with functional parameters.
194 * c-exp.y (func_mod rule): Allow (and ignore) list of parameter
195 types in a function type.
196 * eval.c (parse_and_eval_type), value.h: New function,
197 parse_and_eval_type, is based on old code from check_stub_method.
198 But don't actually evaluate the cast, since that calls
199 value_cast(), whcih may fail. Just extract the type
200 from the parsed expression.
201 * values.c (check_stub_method): While looping through the
202 arguments, adjust depth *after* parameter has been handled.
203 Replace call and setup of parse_and_eval with new function
206 Tue Nov 12 09:40:07 1991 Fred Fish (fnf at cygnus.com)
208 * utils.c, rem-multi.shar: Remove fixed arg count version of
211 * altos-xdep.c, arm-xdep.c, coffread.c, command.c, convex-xdep.c,
212 core.c, dwarfread.c, gould-xdep.c, infcmd.c, language.c,
213 m88k-xdep.c, main.c, printcmd.c, pyr-xdep.c, source.c,
214 sun386-xdep.c, symm-xdep.c, umax-xdep.c, values.c, xcoffread.c:
215 Change all instances of use of fixed args concat() to variable
216 args concat() now located in libiberty.
218 Tue Nov 12 07:23:46 1991 John Gilmore (gnu at cygnus.com)
220 * Makefile.in: Add xcoffread.c, xcoffexec.c.
221 * xcoffread.c: New file for handling AIX mangled-coff files.
222 * xconfig/rs6000, tconfig/rs6000: New files.
223 * buildsym.c: Add hooks for xcoffread.c.
224 * rs6000-pinsn.c, rs6000-tdep.c, rs6000-xdep.c, tm-rs6000.h,
225 xm-rs6000.h, rs6k-opcode.def, rs6k-opcode.h: New files.
226 * xcoffexec.c: New file for handling AIX shared libraries.
228 Mon Nov 11 19:14:31 1991 Fred Fish (fnf at cygnus.com)
230 * core.c: Minor rewording of message to user containing name of
231 (and possibly arguments to) the program that generated a core
234 * elfread.c: Remove the register_addr() stub now that it is no
237 * procfs.c: Move misplaced #endif for ATTACH_DETACH. Add new
238 fetch_core_registers() function for core file support.
240 Sat Nov 9 13:37:57 1991 Fred Fish (fnf at cygnus.com)
242 * dwarfread.c (dwarf_psymtab_to_symtab): Remove leftover call
243 to do_cleanups() which resulted from a previous change.
245 * elfread.c: Re-enable compilation of register_addr() stub
246 whenever it is not supplied by coredep.c
248 Sat Nov 9 00:40:32 1991 John Gilmore (gnu at cygnus.com)
250 Add tracking of object files (that contain symbols) to gdb.
251 This includes a "struct objfile" that owns symtabs and psymtabs
252 that were read in from that binary file.
254 * symfile.h: Add struct objfile. Add pointer to the objfile
255 into the struct sym_fns.
256 Replace global `symfile' and `symfile_mtime' with
257 `symfile_objfile'. Add global object_files chain.
259 * symfile.c: Move param.h above symtab.h.
260 (sort_misc_function_vector): Add.
261 (syms_from_objfile): Was syms_from_bfd.
262 (symfile_open): Now returns objfile.
263 (allocate_objfile): New.
264 (free_objfile): New, replacing free_all_.*symtabs.
265 (symfile_init): Takes objfile arg, puts it in sym_fns result.

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

284 * buildsym.c (end_symtab): Pass objfile.
285 (dbx_lookup_type): Handle null typevector.
286 (dbx_alloc_type): Check file number, not sym number, for -1.
287 (find_symbol_in_list): Add for xcoffread.
288 (start_symtab): Default typevector is empty. Keep reusing same
290 (end_symtab): Take objfile argument and pass it to
291 allocate_symtab. Don't make a symtab if no blocks or symbols.
292 Handle empty typevector.
293 (push_context): New function for context stack nesting.
294 (read_type): Mark FIXME where we need to reintroduce type smashing.
296 * buildsym.h (pop_context): Macro, paired with push_context.
297 (subfile_stack): Move here from dbxread.c.
299 * coffread.c (end_symtab, read_coff_symtab): Take and use objfile arg.
300 (read_coff_symtab): Cleanup by freeing objfile, not all symtabs.
302 * mipsread.c (read_mips_symtab, parse_partial_symbols, parse_fdr,
303 new_psymtab, new_symtab): Take and use objfile arg.
305 * dwarfread.c (scan_compilation_units, start_psymtab,
306 process_dies, end_symtab, dwarf_build_psymtabs,
307 read_lexical_block_scope, read_func_scope, read_file_scope): Take
308 and use objfile argument.
309 (psymtab_to_symtab_1, read_ofile_symtab): Don't take or use file
310 descriptor. Use BFD internal functions instead.
311 (end_symtab): Call global allocate_symtab.
313 * elfread.c, target.c: Minor changes to accommodate objfiles.
314 * symtab.h: partial_symbol_table has no symfile_name member now.
315 (fn_fieldlists voffset): avoid non-int bitfield.
316 (struct symtab): Add objfile * and objfile_chain * of symtabs.
317 (struct partial_symtab): Add objfile * and objfile_chain * of
318 psymtabs. Remove symfile_name.
320 * symmisc.c: Lose free_all_symtabs, free_all_psymtabs.
321 (printsyms_command): Rename from print_symtabs. Add selective
322 listing if 2nd argument given. Print objfile info.
323 (printpsyms_command): Rename from print_partial_symtabs. Ditto all.
324 (printobjfiles_command): New; prints objfiles lists, and checks

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

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

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

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

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

902 Fri Sep 20 16:10:52 1991 John Gilmore (gnu at cygnus.com)
906 * Makefile.in (VERSION): Set to 4.1.
907 * language.c (set_language_command): Print useful help message,
908 and restore the language string after giving help.
909 * valprint.c (typedef_print): Print typedef in C or M2.
910 * symtab.c (list_symbols): Use it.
911 * main.c (main): Avoid any output before (gdb) prompt when -q.
912 * language.c (set_language_command): Handle errors by restoring
913 the language string to its current state (fix from A. Beers).
914 * doc/gdbint.texinfo: Roll in information from README. Rearrange
915 "how to install" and "how to print the doc" stuff so it drops
917 * configure.in: Rename rtpc CPU to romp to match config.sub.
918 * README, WHATS.NEW, TODO: Update for gdb-4.1.
920 Fri Sep 20 17:39:14 1991 Roland H. Pesch (pesch at cygnus.com)
922 * doc/gdb.texinfo: Updates from ChangeLog. set/show write,
923 autoloading shared libs, copyright etc on GDB startup, clean up $_
924 and $__ index refs, set/show listsize and related updates to list
925 cmd. New host/target configs.
927 Fri Sep 20 15:46:00 1991 Roland H. Pesch (pesch at cygnus.com)
929 * doc/Makefile: generate aux version-no file doc/gdbVN.m4
930 from main Makefile.in version definition
931 doc/gdb.texinfo: use version recorded in doc/gdbVN.m4 for current
933 Makefile.in (setup-to-dist): generate doc/gdbVN.m4
935 * doc/gdb.texinfo: merge new language-switching and lang-specific
938 Fri Sep 20 15:00:57 1991 Per Bothner (bothner at cygnus.com)
940 * mcheck.c: Add __ONEFILE kludge to allow compilation by non-ANSI
941 compilers (which may lack stddef.h).
943 Fri Sep 20 13:29:42 1991 John Gilmore (gnu at cygnus.com)
945 * dbxread.c (read_dbx_symtab, process_one_symbol): N_FN and
946 N_WARNING are the same except for the N_EXT bit, so just use their
947 values alone, rather than OR-ing them with N_EXT.
949 Fri Sep 20 12:27:55 1991 Stu Grossman (grossman at cygnus.com)
951 * mipsread.c (parse_lines): Deal with negative extended line
954 * c-exp.y, m2-exp.y: #define yyerrflag and yynerrs to avoid
955 global symbol conflicts.
957 Fri Sep 20 02:28:15 1991 John Gilmore (gnu at cygnus.com)
959 * .gdbinit: Move 'set complaints' to top, so it runs even in
960 case we aren't debugging GDB.
961 * language.c (_initialize_language): Fix type check and range
962 check documentation strings.
963 * utils.c (!HAVE_VPRINTF): Define vfprintf as a function, so
964 language.c can use it. (Though language.c should really not be
965 handling warnings/errors the way it does, FIXME.)
966 * symtab.c (lookup_primitive_type): const lint.
968 Bugfix from Peter Schauer:
969 * source.c (lines_to_list): Make signed, to avoid comparison
970 going unsigned and complaining that -3 is too high for 21 lines.
971 * stack.c (lines_to_list): Ditto.
973 Thu Sep 19 23:33:41 1991 John Gilmore (gnu at cygnus.com)
975 * Makefile.in (HFILES): Add minimon.h.
976 (VERSION): Roll version number to 4.0.95.
977 (gdb.tar.Z, make-proto-gdb.dir, setup-to-dist, gdb-XXX.tar.Z):
978 New rules for building distributions. Normal distribution
979 is built by doing `make -f Makefile.in gdb.tar.Z' in the directory
980 one level up from here; it calls make-proto-gdb.dir to build a
981 directory `proto-gdb' which is an image of the release. The old
982 `gdb.tar.Z' rule still works too.
983 * config.sub, configure: Roll in latest from ..
985 Thu Sep 19 17:41:24 1991 Roland H. Pesch (pesch at cygnus.com)
987 * doc/gdbint.texinfo: Reorder contents; reorganize new-host,
988 new-target, and new-config chapters; fix minor typos; come closer
989 to usual GNU markup conventions for @file @samp @code @var.
991 Thu Sep 19 17:04:12 1991 Per Bothner (bothner at cygnus.com)
993 Patches from Peter Schauer <pes@regent.e-technik.tu-muenchen.de>:
994 * mipsread.c (parse_partial_symbols): Enter the name of all
995 structs/unions... into the psymtab so we can access them if the
996 symtab is not read in.
997 * mips-tdep.c: Remove some unneeded #includes.
998 * xconfig/dec3100: Add HAVE_STRSTR.
1000 Thu Sep 19 15:14:23 1991 John Gilmore (gnu at cygnus.com)
1002 * Makefile.in: Circumvent Sun Make bug on *-exp.tab.o.
1003 * c-exp.y, m2-exp.y: Lint.
1004 * m2-exp.y: Avoid using yytname[] which is a Bison-ism.
1005 * valprint.c (val_print_fields): Check for stub type.
1006 * mipsread.c (_initialize_mipsread): Avoid using
1007 builtin_type_void at initialize time.
1008 (mipscoff_symfile_read): use it now.
1010 Wed Sep 18 15:55:51 1991 John Gilmore (gnu at cygnus.com)
1012 Merge multiple-language support, and partial Modula-2 support,
1013 from Andrew Beers <beers@cs.buffalo.edu>.
1015 * i387-tdep.c: New file, consolidates most 80387 support,

1109 Tue Sep 17 08:37:41 1991 John Gilmore (gnu at cygint.cygnus.com)
1111 Add Andrew Beers' changes for Modula-2 support. His ChangeLog
1112 entries are enclosed herein. Not all of these changes
1113 have been merged into the master GDB sources -- check the
1114 ChangeLog above here for the merge log.
1116 Mon Jun 3 17:05:45 EDT 1991
1118 m2-exp.y Created. Tested outside of GDB for a few days. Proper
1119 operators were added, C specific operators and tokens
1120 removed. yylex() revamped to some extent. Still things
1121 missing from the grammar, such as sets.
1122 Tested for two weeks in GDB v3.5.
1124 Tue Jun 11 17:23:48 EDT 1991
1126 m2-exp.y Added boolean constants TRUE and FALSE to the grammar
1127 so they are built-in. Sort of a hack.
1129 Fri Jun 14 12:53:51 EDT 1991
1131 m2-exp.y Added range checking for numeric constants. Any numeric
1132 constant is assumed to be of builtin type INTEGER unless:
1133 (1) it is octal or hexadecimal, in which case it is a
1134 CARDINAL; (2) it is too big to fit into an INTEGER, in
1135 which case it is a CARDINAL.
1136 eval.c Added simple range checking for +, -, and * on integers.
1137 Doesn't work very well for *, since 6 * 1,000,000,000 =
1138 1,705,032,704, which fails the simple test of result >=
1139 first_operand, no matter in what order the operands are.
1141 Tue Jun 18 14:11:30 EDT 1991
1143 Broke the parser into parts, one containing the C grammar and the other
1144 containing code to be shared by all of the grammars.
1146 The following files no longer exist:
1151 The following files were added:
1153 c-exp.y (The C grammar)
1154 m2-exp.y (The Modula-2 grammar)
1155 parser-code.c (Code that is shared by the above grammar)
1159 Makefile.dist Changed to reflect the above dependencies. NOTE: It is
1160 now necessary to use the Bison compiler compiler, since it
1161 will generate function/variable prefixes other than yy.
1163 Tue Jun 18 16:47:49 EDT 1991
1165 symtab.[ch] Added the external variable working_lang, than holds the
1166 value of the current working language.
1167 Added the ennumerated type language_mode, with the values
1168 language_auto and language_manual, the former meaning that
1169 GDB sets working_lang as needed, and the latter meaning
1170 that the value of working_lang is totally under user
1172 symtab.[ch] Added the Modula-2 pervasive types INTEGER, CARDINAL,
1173 REAL, BOOLEAN and CHAR. Also added the type codes
1174 TYPE_CODE_BOOL and TYPE_CODE_CHAR.
1175 utils.c Added set_language_command and show_language_command to
1176 implement the GDB support commands "set language" and
1178 expression.h A number of identifiers were added to the type exp_opcode
1179 to facilitate Modula-2 builtin functions, integer
1180 division, and array indexing.
1182 Wed Jun 19 13:25:58 EDT 1991
1184 language.h Added the macro STRICT_TYPE, which evaluates to non-zero
1185 if the language specified by working_lang requires the use
1186 of strict typing of expressions. Eventually, even this
1187 will be able to be changed by the user.
1188 Added the macro RANGE_CHECK, which evaluates to non-zero
1189 if the language specified by working_lang requires the
1190 checking of a value against the domain of its type.
1191 Eventually, even this will be able to be changed by the
1193 language.[ch] Predicates involving types (simple_type, ordered_type,
1194 same_type, integral_type, numeric_type, character_type,
1195 boolean_type, float_type) are added. These predicates are
1196 based on the current value of working_lang, and are handy
1199 Wed Jun 19 15:39:34 EDT 1991
1201 eval.c Added the function type_array_rank which computes the rank
1203 valarith.c Added the funtion value_bool, which when given a integer
1204 value.h value (ie. struct value *) as an argument, it returns a
1205 boolean value (ie. struct value *) true if that integer
1206 is non-zero, and a boolean value false otherwise.
1207 valprint.c Added cases for TYPE_CODE_BOOL, so Modula-2 BOOLEAN values
1208 will print out properly.
1210 Wed Jun 19 16:36:34 EDT 1991
1212 valops.c Added the function value_capitalize, which returns it
1213 value.h argument capitalized if its argument is a lowercase
1214 letter, or the argument unchanged if its argument is not a
1216 valarith.c Added the function range_check_p, which returns non-zero
1217 value.h if its value argument is between the integral bounds upper
1219 Added the function range_check_enum_p, which makes sure
1220 that its value argument is a valid member of the domain of
1222 Added the function range_check_range_p, which makes sure
1223 its value argument lies between the upper and lower bounds
1224 of its type argument, which must be a ranged type.
1225 Added the function check_array_index, which range and type
1226 checks an index of an array.
1227 Added the function value_multi_subscript, which computes
1228 array[idx1,idx2...idxN], given a value array and an array
1229 of values representing indicies.
1230 values.c Changed value_from_long to work with TYPE_CODE_CHAR and
1231 unpack_long to work with TYPE_CODE_BOOL and
1234 Wed Jun 19 18:04:08 EDT 1991
1236 symtab.c Stored pervasive types in a structure and make
1237 lookup_pervasive_type() a lookup function that was based
1238 on working_lang. If lookup_pervasive_type() returned
1239 non-zero, then that value was returned (a fix, since
1240 before it simply wouldn't return the pervasive type.)
1241 language.h Added the macro CAST_IS_CONVERSION, which evaluates to
1242 non-zero if the language specified by working_lang means
1243 "conversion" when it says "cast".
1244 valops.c Added the function value_real_cast(), which performs a
1245 value.h *cast*, not a *conversion*, which is what value_cast()
1246 does when it can. In particular,
1247 value_cast(<float_type>,4) = 4.0, while
1248 value_real_cast(<float_type>,4) = some mess.
1249 eval.c Modula-2 builtin functions implemented: ABS, CAP, CHR,
1250 parser-code.c FLOAT, HIGH, MAX, MIN, ODD, ORD, TRUNC, and VAL.
1251 expression.h Added macros MAX_OF_TYPE and MIN_OF_TYPE to work with MAX
1252 and MIN on integral types. *NOTE*: These are currently
1253 hardcoded to work only if there are 8 bits per storage
1255 eval.c Made logical functions call value_bool to return a
1256 properly typed boolean value, based on working_lang.
1258 Thu Jun 20 11:55:27 EDT 1991
1260 valprint.c Types now print out in a Modula-2 fashion. This works for
1261 the cases when the type is printed out step-by-step, that
1262 is, it doesn't work when the name of a structured type
1263 (which includes the keyword "struct", etc.) is simply
1265 FIXME: Perhaps this is bad. Parts of it seem to kludgey,
1266 since type specifications in C and Modula-2 are very
1267 different. The C printing of a type is very recursive,
1268 whereas in Modula-2 it is generally very simple. C has
1269 type prefixes and suffixes, which have no real analogue in
1270 Modula-2. Maybe type_print() should call a language
1271 specific type printer. This is also advantageous if we
1272 compile GDB to exclude some of the languages. We'll just
1273 leave those functions out.
1275 Thu Jun 20 16:57:10 EDT 1991
1277 dbxread.c When reading the complete symbol table in (via
1278 psymtab_to_symtab()), the number and types of function
1279 arguments are added to a function type. define_symbol()
1280 calls add_param_to_type() to accomplish this.
1281 Assumption: when we come across a function definition
1282 (N_FUN symbol with an 'f' or 'F' in the name), its
1283 arguments will appear before another function definition.
1284 When a function is found, a pointer to its type is placed
1285 in the global in_function_type. Changes that
1286 add_param_to_type() makes are to this global.
1287 valprint.c The type of a function now includes (for Modula-2) the
1288 types of its parameters.
1289 eval.c Type checking and a check for the proper number of
1290 arguments is now done for function calls. Not sure of the
1291 impact this has on C++ member function yet.
1293 Thu Jun 20 19:58:48 EDT 1991
1295 valprint.c Rewrote the type printer. Broke it into two language
1296 specific parts, adding the functions type_print_m2() and
1298 An unfortunate consequence is this: if you debugging a C
1299 program in Modula-2 mode (why?), info types does not work
1300 well with regular expressions, since the types are printed
1301 out in Modula-2 terminology, but stored in C terminology.
1302 language.[ch] Added the functions new_type_last(), type_keyword(), and
1303 type_sep() to aid in the printing of typedefs.
1304 symtab.c Made the printing of typedefs as language independent as
1305 possible through calls to new_type_last(), type_keyword(),
1308 Fri Jun 21 11:50:26 EDT 1991
1310 dbxread.c Check all incoming ennumerated types. If it looks like
1311 Modula-2's BOOLEAN type, then change the type_code of the
1312 type to TYPE_CODE_BOOL so we can process it as a boolean
1314 valprint.c Replaced some of the 0x%x with calls to sprintf and
1315 hexformat() in val_print().
1316 language.[ch] Added the function hex_to_string(), which converts its
1317 integral argument to a hexadecimal number (format is
1318 language based) and returns the result as a string.
1320 Mon Jun 24 12:25:07 EDT 1991
1322 valprint.c Some functions call type_print_1() directly, instead of
1323 value.h using type_print(), so they can specify where (column) to
1324 print things. Since type_print() takes care of language
1325 dependence, that needs to be called first. Added a
1326 parameter depth to type_print() (so it is now like
1327 type_print_1). Changed type_print to type_print_at, and
1328 made type_print a macro that passes a depth argument of
1330 symmisc.c Changed all calls to type_print_1 to calls to
1332 Makefile.dist Made it possible to build GDB for a specific set of
1333 depend languages. Do this by passing a definition for the macro
1334 LANGS to make. LANGS should be a string containing a
1335 space-separated list of language names (ie. LANGS="c m2").
1336 The default is to build all languages. Note that grammar
1337 files must follow the naming convention of <lang>-exp.y.
1338 gdb.lang This holds the current value of the LANGS macro. It is
1339 examined every time make is called, and is updated if
1341 eval.c Added #ifdef _LANG_<lang> to these files.
1342 expread.c Still need to add them to dbxread.c and coffread.c.
1350 Mon Jun 24 16:33:11 EDT 1991
1352 language.[ch] Added the functions hexformat_pre() and
1353 hex_to_string_pre(), which take a prefix argument to
1354 include in the format string. Thus, hexformat_pre("08") will
1355 return "0x08x" (if the working language is language_c).
1356 Made hexformat() and hex_to_string() calls to the above
1357 with "" as the prefix argument.
1359 am29k-pinsn.c, arm-pinsn.c, breakpoint.c, convex-tdep.c, exec.c, core.c,
1360 dbxread.c, i386-pinsn.c, i386-stub.c, i386-xdep.c, i960-pinsn.c,
1361 infcmd.c, inflow.c, m68k-pinsn.c, m68k-stub.c, m88k-pinsn.c,
1362 mips-pinsn.c, mips-tdep.c, ns32k-pinsn.c, printcmd.c, pyr-pinsn.c,
1363 pyr-tdep.c, pyr-xdep.c, remote-vx.c, remote.c, solib.c, source.c,
1364 stack.c, sun386-xdep.c, symfile.c, symm-xdep.c, symmisc.c, tahoe-pinsn.c,
1365 valprint.c, vax-pinsn.c
1367 Changed all occurences of 0x%[0-9]*l*x in printf format strings to
1368 calls to hexformat() and hex_to_string(). Format strings without
1369 the leading "0x" were ignored.
1371 depend Updated to take the above into account.
1374 Tue Jun 25 15:27:18 EDT 1991
1376 symtab.h Added the types range_mode_t, range_check_t, type_mode_t,
1377 and type_check_t to keep track of the current state of
1378 range and type checking.
1379 main.c Added the variables range_mode, range_check, type_mode,
1380 and type_check to record the current state of range and
1381 type checking. Added initialization code to main().
1382 language.h Changed the macros STRICT_TYPE and RANGE_CHECK to examine
1383 the above variables.
1386 Tue Jun 25 17:57:08 EDT 1991
1388 dbxread.c process_one_symbol() updates the variable (enum language)
1389 source_lang based on the extension of the filename
1390 contained in the N_SO sybmol that started this symtab.
1391 When end_symtab() is called, the value of source_lang is
1392 put into the language field.
1393 stack.c select_frame() sets working_lang (and possibly type_check
1394 and range_check) to the language field of the symtab
1395 associated with the frame that is selected if working_mode
1396 is language_auto. If working_mode is language_manual, a
1397 warning is printed and working_lang is not set.
1398 language.c Added the function set_type_range(), which sets the value of
1399 type_check and range_check (if their modes call for
1400 automatic setting) based on the current value of
1401 working_lang. A non-zero argument will cause the current
1402 settings to be output.
1405 Wed Jun 26 14:51:40 EDT 1991
1407 eval.c Added range checks on assignment.
1408 m2-exp.y Added the grammar for sets to the language. Currently,
1409 these do not do anything except print an error message.
1411 Wed Jun 26 17:01:04 EDT 1991
1413 m2-exp.y Added the ability for parse_number() to parse negative
1414 numbers. A global flag is set upon encountering a unary
1415 minus. This was done to make, for example, 1 parse as a
1416 CARDINAL, and not as an integer, per Wirth's examples in
1417 Programming in Modula-2 ed.4.
1418 valprint.c Added support for "set radix 2" by then setting
1419 output_format to 't'.
1420 eval.c Implemented range checking on subrange types. Added calls
1421 to range_check_range_p for BINOP_ASSIGN and BINOP_VAL.
1422 Implemented MIN and MAX for ennumerated types. The
1423 minimum value of an ennumerated type is defined by Wirth
1424 as the first identifier, and the maximum as the last.
1425 m2-exp.y Made octal numbers ending with "B" be characters and those
1426 ending with "C" be numbers, per Wirth's book. (p. 34)
1428 Thu Jun 27 14:11:52 EDT 1991
1430 stack.c select_frame() now only sets working_lang, it does not
1431 notify the user. If working_mode is language_manual, then
1432 a warning is issued once.
1433 main.c At the end of each call to execute_command(), working_lang
1434 is checked against the local static (enum language)
1435 current. If they differ and working_mode is
1436 language_auto, the new settings of language, type and
1437 range checking are printed out.
1438 stack.c Modified frame_info() to include the language of the
1439 current frame in the output of "info frame".
1440 language.[ch] Added the function language_str() which returns the name
1441 of the current language.
1443 Fri Jun 28 15:33:14 EDT 1991
1445 m2-exp.y Added the built-in procedures INC, INCL, DEC, and DECL to
1446 the language. INCL and DECL currently cause an error,
1447 since sets are not implemented yet. INC and DEC are
1448 implemented as PREINCREMENT/PREDECREMENT with one
1449 argument, and as ASSIGN_MODIFY with two arguments.
1450 eval.c Added type checking to the above cases.
1451 value.h Added not_lval_constant to the lval_type ennumerated type.
1452 not_lval_constant means that the value is a constant
1453 value; that is 3 or 'a' or TRUE, not as in a constant
1454 identifier. This is used to help coerce numbers such as 3
1455 to either signed or unsigned numbers.
1456 valops.c Added the function value_coerce_constants() which coerces
1457 constant integers as following: if one is a constant and
1458 the other is not, the constant's type is set to the type
1459 of the other argument. If both are constants and one is
1460 signed, the other is converted to a signed constant.
1462 Sat Jun 29 17:26:29 EDT 1991
1464 valarith.c Added a better range checker. It now checks range
1465 (successfully) on integral operations [+-] (signed and
1466 unsigned) for any C sized type. Still does not work well
1467 for multiplication.)
1468 int_in_size() returns an integer that is coerced to fit into
1469 specified number of bytes.
1471 Mon Jul 1 13:04:14 EDT 1991
1473 language.[ch] Added the function binop_result_type(), which returns the
1474 builtin (struct type *) type that would be the result of a
1475 binop on the two values V1 and V2.
1477 Wed Jul 3 19:22:53 EDT 1991
1479 source.c Extended source_info() to include the source language in
1480 the output from "info source".
1482 Fri Jul 5 13:48:52 EDT 1991
1484 utils.c Moved the support functions for the GDB set/show commands
1485 dealing with language into language.c.
1486 language.c Added the function language_info(), which displays info
1487 about the current working language, type and range check
1488 settings. Called via the GDB command "info language".
1489 Added an initialization routine _initialize_language(),
1490 that sets defaults for the language, type and range
1491 variables and sets up the new GDB commands.
1492 main.c Language setup moved to language.c.
1495 Mon Jul 8 10:10:22 EDT 1991
1497 valarith.c Debugged the range checker for arithmetic. Still does not
1498 work for multiplication very well.
1500 Mon Jul 8 12:40:37 EDT 1991
1502 language.[ch] Added the function value_true() which returns non-zero if
1503 its argument represents a boolean true value.
1504 breakpoint.c Changed breakpoint_cond_eval() to call value_true() to
1505 check the truth of an expression.
1507 Thu Jul 11 12:51:34 EDT 1991
1509 language.[ch] Added the predicate structured_type(), which returns
1510 non-zero if the argument is a structured type.
1511 Added the predicate pointer_type(), which returns non-zero
1512 if the argument is a pointer type.
1513 eval.c Added the ability to do addition and substraction on
1514 pointers and integers. This case simply bypasses the
1517 Thu Jul 11 14:41:42 EDT 1991
1520 Added the symbol N_DEFD (0x4a) which is a definition
1521 module dependency that is used by the GNU Modula-2
1522 compiler and the linker. It is not important to GDB,
1523 except that [dbx|coff|mips]read.c should ignore these
1526 Fri Jul 12 16:07:00 EDT 1991
1528 valprint.c Changed the TYPE_LENGTH(type) >= 0 to TYPE_LENGTH(type) >
1529 0 in val_print(). Also added statements to the else part
1530 to coerce type (argument to val_print) to a pointer type
1531 if it is an "array of unspecified length".
1532 valops.c Added the function value_m2_string(), which returns a
1533 (value) value which is a constant string, whose type is
1534 (ARRAY [0..n] OF CHAR). The length field of the type
1535 structure is set to zero, so it will be interpreted as an
1536 "array of unspecified length".
1537 stack.c Moved the language/frame mismatch check to
1538 main.c:execute_command().
1539 main.c The working language is recorded each time
1540 execute_command() is executed. If working lang has
1541 changed during its execution, then the new
1542 language/type/range info is printed out for the user. If
1543 the working language does not match the language of the
1544 frame, a warning is issued.
1546 Sat Jul 13 16:16:39 EDT 1991
1548 eval.c Moved all the type-checking stuff for operators to
1549 language.[ch] language.c. This is so we can keep language-specific
1550 stuff (like for what type operators are defined) in
1552 language.[ch] Added the function binop_type_check(), which checks to see
1553 if its two (value) arguments are type-compatible with its
1554 opcode argument. The opcode should represent an operation
1555 involving an operator. Also added the macro function
1556 unop_type_check, which calls binop_type_check with a
1557 NULL second argument.
1558 expprint.c Added Modula-2 operators to the op_print_tab, so info
1559 expression.h break works correctly. Also added "op_string", which
1560 returns the string corresponding to the (enum exp_opcode)
1561 opcode that is its argument.
1564 Sat Jul 13 18:26:18 EDT 1991
1566 coffread.c Added code to record the type of function arguments with
1567 each paricular function. Code is very similar to that
1569 dbxread.c Moved add_param_to_type() to symtab.c
1570 symtab.[ch] Added function add_param_to_type() from dbxread.c
1572 *** NOTE: The above additions have not been tested.
1574 Mon Jul 15 12:50:47 EDT 1991
1576 langauge.[ch] Added the functions type_error and range_error, which work
1577 like error() except if the type/range mode is set to
1578 *_mode_warn, then they do not do a return_to_top_level(),
1579 but merely print a warning.
1580 Also changed [set|show]_[type|range]_command() to support
1581 the new "warn" feature.
1583 Thu Jul 18 17:50:54 EDT 1991
1585 mipsread.c Added code to record the type of function arguments with
1586 each particular function. Code is very similar to that
1589 *** NOTE: The above additions have not been tested.
1591 Fri Jul 19 11:19:10 EDT 1991
1593 defs.h Added macros MAX_OF_SIZE, MIN_OF_SIZE, UMAX_OF_SIZE, and
1594 UMIN_OF_SIZE, which when given a size of a numeric type,
1595 return the maximum and minimum value it can hold. UMAX...
1596 and UMIN... return the result for unsigned types.
1597 symtab.h Added the macros MAX_OF_TYPE and MIN_OF_TYPE to operate on
1598 struct types. They call above macros.
1599 dbxread.c Renamed the MAX and MIN_OF_TYPE macros to ..._OF_CTYPE to
1600 avoid a name conlict with the above.
1601 c-exp.y Added range checking on numeric constants in
1602 parse_number() for completeness.
1603 valarith.c Made binop_user_defined_p() and unop_user_defined_p()
1604 return 0 if working_lang is not language_c.
1606 Thu Aug 8 14:17:22 EDT 1991
1610 breakpoint.c Documentation strings of some commands changed to
1611 eliminate the references to the C language where
1614 Tue Aug 13 15:48:03 EDT 1991
1616 m2-exp.y Added qualified identifiers to the grammar. The semantics
1617 are slightly different from those of the GDB operator ::
1619 m2-exp.y Added a rule to each grammar of the form: start ::= exp |
1620 type_exp, where type_exp is any valid type expression.
1622 eval.c Added the opcode OP_TYPE, and an error case in eval.c.
1623 printcmd.c Modified ptype_command() so it actually parses the input
1624 (necessary for type expressions with scope qualifiers).
1625 Added the function ptype_eval() which expects an
1626 expression composed of one OP_TYPE element.
1627 *.[ch] Replaced all occurences of parse_c_expression with
1629 *.[ch] Replaced all occurences of parse_c_1 with parse_exp_1
1631 [End of ChangeLog entries from Andrew Beers for Modula-2 support.]
1633 Mon Sep 16 17:19:46 1991 John Gilmore (gnu at cygnus.com)
1635 Small fixes from Peter Schauer:
1637 * infrun.c (child_attach): Lint.
1638 * solib.c (find_solib): Handle shared libs version 2.
1640 Small fixes from David Wood:
1642 * xm-ultra3.h (SYS_SIGLIST_MISSING): Typo.
1646 * remote-vx.c: Move <stdio.h> to top, for FILE. Fix from
1647 John S <basrai%kanga.dnet@c3po.sm-alc.af.mil>.
1649 * utils.c (wrap_here): Avoid wrap action of fputs_filtered if
1650 chars_per_line is at maximum (user typed `set width 0'). Fix
1651 from Andreas Schwab <schwab@ls5.informatik.uni-dortmund.de>.
1653 Tue Sep 17 17:31:04 1991 Stu Grossman (grossman at cygnus.com)
1655 * coredep.c: include ptrace.h where necessary.
1656 * mipsread.c(parse_lines): fix unsigned char problem that was
1657 messing up line numbers on SGI's and possibly other MIPS based
1659 * infrun.c (child_create_inferior): use better test to check
1660 return val from setpgrp().
1661 * tm-irix3.h, xm-irix3.h, tconfig/irix3, xconfig/irix3: add these
1662 for sgi/irix support.
1664 Wed Sep 18 04:33:31 1991 Per Bothner (bothner at cygnus.com)
1666 * mipsread.c (parse_symbol): Put non-static procedures
1667 in the global block.
1669 Fri Sep 13 00:14:52 1991 John Gilmore (gnu at cygnus.com)
1671 Patch together `text_start' and `text_end' for 29K port.
1673 * exec.c (exec_command): If NEED_TEXT_START_END, define the
1674 variables and set them based on the exec file.
1675 * am29k-tdep.c: declare text_start.
1676 * valops.c (call_function_by_hand): declare text_end.
1678 * inferior.h: Eliminate CANNOT_EXECUTE_STACK in favor of
1679 defining CALL_DUMMY_LOCATION as BEFORE_TEXT_END. This is
1680 because machines that do this will also have to know to
1681 set NEED_TEXT_START_END. Besides, it was a redundant way to
1683 * tm-29k.h, tm-convex.h, tm-np1.h: Eliminate
1684 CANNOT_EXECUTE_STACK, define CALL_DUMMY_LOCATION and
1685 NEED_TEXT_START_END.
1687 Thu Sep 12 00:22:24 1991 John Gilmore (gnu at cygint.cygnus.com)
1689 AMD 29000 changes from David Wood <wood@david.ultra.nyu.edu>:
1691 * Makefile.in (CLIBS): Put XM_CLIBS and TM_CLIBS at end.
1692 Pass MUNCH_DEFINE to munch whenever we run it.
1693 * am29k-pinsn.c (print_insn): Handle NOP specially. Avoid %#x
1694 format string; use 0x%x instead.
1695 * am29k-tdep.c: Use DUMMY_SAVE_GREGS and RETURN_REGNUM.
1696 * ultra-xdep.c, xm-ultra.h: New files for Ultracomputer host system.
1697 * xm-rtbsd.h: New host support for RT/PC running BSD Unix.
1698 * inflow.c: Handle `short' process group IDs.
1699 * infptrace.c (fetch_register): Support CANNOT_FETCH_REGISTER,
1700 and check for ptrace errors.
1701 * coffread.c (SDB_REG_TO_REGNUM): Define if not already.
1702 (coff_symfile_init): Initialize text_bfd_scnum.
1703 (read_coff_symtab): Use it to find the text [and absolute?] sections.
1704 * ../config.sub: Add vendor nyu and os "sym[1-9]*".
1705 * configure.in: Add hosts rtpc-*-* and a29k-*-*.
1706 Merge target arm case with other "easy" cases. Add target
1707 cases a29k-*-none (rehack of am29k), a29k-*-kern (remote to
1708 Ultracomputer kernel), and a29k-*-sym1 (ultracomputer OS's user
1710 * minimon.h, remote-adapt.c, remote-mm.c: Add.
1711 * munch: Cope with RT/PC putting fns in data segment.
1712 Restore ability to override `nm' by specifying MUNCH_NM.
1713 * xconfig/rtbsd, xconfig/ultra3: New host systems.
1714 * tconfig/a29k: Rename from tconfig/am29k. Add remote-mm
1715 and remote-adapt. Remove encapsulated coff #define's (the
1716 support should go in BFD, and gdb shouldn't know or care).
1717 * tconfig/a29k-kern: Same, but for remote kernel debugging.
1718 * tconfig/ultra3: For debugging user processes on Ultra3/Sym1.
1719 * tm-29k.h: Update BADMAG (though it should go away).
1720 Allow the register definitions to be overridden in another
1721 tm-file. Fix SR_REGNUM. Add a mess of _REGNUM's. Separate
1722 RETURN_REGNUM from GR96_REGNUM and DUMMY_SAVE_GREGS from
1723 DUMMY_SAVE_GR96, for handling kernel calling conventions
1724 that use GR64+ rather than GR96+.
1725 * tm-ultra3.h: New file, for use on Ultra3 Unix as well as for
1726 remote debugging of Ultra3 kernel. Includes tm-29k.h and
1727 overrides various things.
1729 * remote-mm.c (mm_attach, mm_wait): Handle attach like
1730 child_attach does, making a clean stop in the newly attached
1732 * remote-eb.c: Lint.
1734 * coffread.c: Make coffread independent of any particular
1735 variant of COFF. Avoid #include-ing any particular one except
1736 internalcoff.h. BFD now passes key values for symbol reading
1737 as part of its coff_data structure (LINESZ, SYMESZ, AUXESZ,
1738 and the symbol masks and shifts); use them.
1739 Remove obsolete end_of_text_addr.
1741 * exec.c: Remove unused include files.
1743 Wed Sep 11 19:38:44 1991 John Gilmore (gnu at cygint.cygnus.com)
1745 * Makefile.in (documentation targets): Pass $(M4).
1746 Bugfix from eggert@twinsun.com (Paul Eggert).
1748 * stack.c (down_silently_command): Check for stack existence.
1750 Tue Sep 10 23:08:29 1991 John Gilmore (gnu at cygint.cygnus.com)
1752 * Makefile.in (VERSION): Update to 4.0.3.
1754 Tue Sep 10 09:19:29 1991 John Gilmore (gnu at cygint.cygnus.com)
1756 * core.c (core_file_command): Print frame at coredump with
1757 its level number, by calling print_stack_frame.
1758 * frame.h: Add selected_frame_level, print_stack_frame.
1759 * frame.h, stack.c: Remove print_sel_frame, print_selected_frame.
1760 * convex-tdep.c, convex-xdep.c, infcmd.c, inflow.c, infrun.c:
1761 Change print_sel_frame and print_selected_frame callers to
1764 * dbxread.c (read_ofile_symtab): Avoid empty else clause.
1765 * symfile.c (free_named_symtabs): Ditto.
1766 * main.c (main): wrap_here needs an arg.
1767 * solib.c (find_solib): Avoid memory access if _DYNAMIC is zero.
1768 (solib_add): Avoid noise.
1769 (solib_create_inferior_hook): Lint.
1770 (sharedlibrary_command): Move dont_repeat to here.
1771 * utils.c (error): Call wrap_here to force buffered output.
1773 Small patches from Peter Schauer:
1775 * coffread.c (start_symtab): Free any existing line_vector before
1777 (read_coff_symtab): Ditto for type_vector.
1779 * source.c (lines_to_list): New variable, replacing function.
1780 (all uses): Use as variable.
1781 (_initialize_source): Add 'set listsize' and 'show listsize'.
1782 * utils.c (lines_to_list): Remove function.
1783 * stack.c (print_frame_info): Use as variable.
1784 * defs.h (lines_to_list): Remove declaration.
1786 Mon Sep 9 13:45:57 1991 John Gilmore (gnu at cygint.cygnus.com)
1788 * breakpoint.c (insert_breakpoints): Restore warning about
1789 the program might be running in another process, but only for
1790 systems with this brain death (#ifdef ONE_PROCESS_WRITETEXT).
1791 * xm-hp300bsd.h, xm-mips.h, xm-vax.h: Define it.
1793 * utils.c (error): if error_pre_print is set, print the string
1795 * main.c (main, print_gnu_advertisement, print_gdb_version):
1796 Reformat legalese so it always prints, but acts as an "I'm here"
1797 message while symbols are being read. If any errors occur,
1798 print a few newlines to set off the message and start it at the
1799 left margin. Remove mention of "help" command, and don't yak
1800 about symbol reading.
1801 (catch_errors): Error string is now printed first in case of
1803 * command.c (undef_cmd_error, lookup_cmd): On undefined command,
1804 suggest the "help" command.
1806 * Makefile.in (VERSION): Set to 4.0.2.
1808 Thu Sep 5 23:49:48 1991 John Gilmore (gnu at cygint.cygnus.com)
1810 * .gdbinit: Remove useless "rr" command. Set complaints
1811 to 1 for people debugging gdb.
1813 * breakpoint.c, remote-vx.c: Reword strings printed by
1814 catch_errors callers.
1816 Wed Sep 4 11:07:50 1991 John Gilmore (gnu at cygint.cygnus.com)
1818 * WHATS.NEW: "history write -> history save". Doc "write on/off".
1819 (Fix from kenc@viewlogic.com.)
1821 Fix some infrastructure to be able to cope with host and target
1822 machines with different sized basic types (ints, ptrs, etc).
1823 (Idea from pierre@la.tce.com (Pierre Willard).)
1825 * values.c (value_from_longest): Rename from value_from_long.
1826 Handle pointer types as well as integers, so that targets with
1827 different pointer sizes from the host can be accomodated.
1828 * breakpoint.c, convex-tdep.c, eval.c, expprint.c, printcmd.c,
1829 valarith.c, valops.c, valprint.c, value.h, values.c: Rename
1830 uses of value_from_long to value_from_longest.
1831 * eval.c, findvar.c, printcmd.c, valarith.c, valops.c: Pass
1832 the correct pointer type to value_from_long{est}.
1834 * doc/gdb.texinfo ($_, $__): Describe types of these variables.
1836 * remote-vx.c: Remove obsolete code for calling functions via
1837 vxworks kludge interface (it referenced value_from_long).
1839 * valops.c (value_string): Find malloc with lookup_misc_func, not
1842 Tue Sep 3 18:37:46 1991 John Gilmore (gnu at cygint.cygnus.com)
1844 Make writing to files work properly. (Fixes to BFD are also needed.)
1846 * core.c (core_open): Open file ourselves, read or r/w, depending on
1847 write_files. Use bfd_fdopenr.
1848 * gdbcore.h (write_files): New variable.
1849 * exec.c (write_files): Define variable, add set&show for it.
1850 (exec_file_command): Use write_files to open for read or r/write.
1852 Make shared library reading happen automatically. These changes
1853 are mostly from Peter Schauer <pes@regent.e-technik.tu-muenchen.de>.
1855 * inferior.h (stop_soon_quietly): Add to exported variables.
1856 * infrun.c (child_create_inferior): call solib hook, if defined.
1857 (child_attach): call solib hook, if defined.
1858 * solib.c: Include inferior.h. Add from_tty to so_list as kludge.
1859 (find_solib): Use lookup_misc_func rather than hand-rolled.
1860 (symbol_add_stub): New stub for catch_errors.
1861 (solib_add): Avoid output if !from_tty. Catch errors rather
1862 than just calling symbol_file_add and bombing.
1863 (solib_create_inferior_hook): Interface with the target process
1864 to let it read and alloc shared libs, then figure out what it did.
1866 * core.c (validate_files): Fix typo, soften warning.
1867 (Fix from Hiroto Kagotani <kagotani@cs.titech.ac.jp>.)
1869 * utils.c (fputs_demangled): Avoid duplicate printing if
1870 demangling is off. (Fix from J.T. Conklin <jtc@cayenne.com>.)
1872 * infrun.c (proceed): Cast -1 to (CORE_ADDR) before comparing.
1873 (Fix from pierre@la.tce.com (Pierre Willard).)
1875 * main.c (catch_errors): Change argument to a char * from an int,
1876 since a char * can point to a struct full of glop, but an int
1877 is not guaranteed to be able to hold a pointer.
1878 * breakpoint.c (breakpoint_cond_eval, bpstat_stop_status,
1879 breakpoint_re_set_one, breakpoint_re_set): Adapt.
1880 * core.c (core_open, solib_add_stub): Adapt.
1881 * remote-vx.c (symbol_stub, add_symbol_stub, callers): Adapt.
1883 Wed Aug 28 18:18:05 1991 John Gilmore (gnu at cygint.cygnus.com)
1885 * Makefile.in: Update VERSION to 4.0.1. Evade GNU Make bug
1886 by adding .NOEXPORT target.
1888 Fri Aug 23 17:14:25 1991 John Gilmore (gnu at cygint.cygnus.com)
1892 * Makefile.in (VERSION): Roll to 4.0.
1893 (gdb.tar.Z): Make refcard.ps as well, for shipment.
1895 Fri Aug 23 14:07:09 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1897 * doc/gdb.texinfo: minor rewordings, crossref to ptype from print,
1900 * doc/Makefile, Makefile.in: generate "gdb-all.texi" rather than
1903 * doc/rdl-apps.texi: renamed from rdl-apps.texinfo
1905 * Makefile.in, doc/Makefile, doc/.Sanitize, doc/gdb.texinfo:
1906 reflect above name change
1908 * WHATS.NEW: correct pointer to refcard.
1910 * doc/gdb.texinfo: update New Features, Installing
1912 * doc/gdbint.texinfo: add short description of configure +template
1914 Fri Aug 23 11:46:08 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1916 * doc/gdb.texinfo: update, fix bugs in "Installing" appendix
1918 Fri Aug 23 01:02:00 1991 John Gilmore (gnu at cygint.cygnus.com)
1920 * Makefile.in: Add config.sub, make doc/rdl-apps.texinfo for
1921 tar file, add dependencies for referenced doc files.
1923 Thu Aug 22 22:17:06 1991 Stu Grossman (grossman at cygint.cygnus.com)
1925 * coffread.c, symfile.c, stack.c: saberized.
1927 Thu Aug 22 16:20:27 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1929 * doc/refcard.tex: permuted Essential Commands sec
1931 * doc/gdb.texinfo: new C++ chapter; revised installation appendix;
1933 set/show symbol-reloading
1934 default set complaints 0
1936 RET-repeat disabled after prompted long displays
1937 processID (attach) interpretation of 2nd GDB cmdline arg
1939 Thu Aug 22 14:05:47 1991 Stu Grossman (grossman at cygint.cygnus.com)
1941 * expread.y, coffread.c, dbxread.c, target.c, mem-break.c,
1942 cplus-dem.c, values.c, valprint.c, symfile.c, remote.c,
1943 breakpoint.c, main.c: lint.
1945 Thu Aug 22 02:02:26 1991 John Gilmore (gnu at cygint.cygnus.com)
1947 Install new configuration scheme for GDB and friends.
1949 * config.sub: Translate ordinary names to three-part names.
1950 * configure: Use three-part names internally.
1951 * configure.in: Translate three-part names to filenames.
1953 * README, WHATS.NEW: Update for gdb-4.0.
1954 * Makefile.in: Roll VERSION to 3.99.
1956 Wed Aug 21 18:21:09 1991 John Gilmore (gnu at cygint.cygnus.com)
1958 * infptrace.c (KERNEL_U_ADDR_BSD): Include a.out.gnu.h.
1959 * i960-tdep.c, m68k-tdep.c, sparc-tdep.c, tm-i960.h,
1960 tm-m68k.h, remote-nindy.c: Change ext_format_XXX structs
1961 to single structures rather than arrays; when passing
1962 their address, use &. This avoids trouble with bdead compilers.
1963 * mcheck.c: Don't include <stdlib.h>; just declare "void abort();"
1964 instead. This avoids portability headaches.
1965 * mips-tdep.c (mips_do_registers_info): Only print FP regs if
1967 * source.c (open_source_file): Avoid ANSI const bdeath by
1968 skipping declaration and then casting result value.
1969 * tm-hp300bsd.h: Clarify comment.
1970 * utils.c (strstr): Result is const char *; ANSI bdeath.
1971 * xm-hp300bsd.h: Define HOST_BYTE_ORDER. Redefine INT_MIN,
1972 since system include file defines it differently from "defs.h",
1973 though the two are equivalent for our purposes.
1974 * tconfig/hp300bsd: Add m68k-tdep.o.
1976 Tue Aug 20 16:01:11 1991 John Gilmore (gnu at cygint.cygnus.com)
1978 * tconfig/sun*4: Remove warnings about system assembler.
1980 Mon Aug 19 13:44:46 1991 John Gilmore (gnu at cygint.cygnus.com)
1982 * mcheck.c: Avoid warning about undeclared abort fn.
1983 * tm-sparc.h (PC_ADJUST): Avoid calling error() from this;
1984 it causes recursive calls to error() when used in cleanups.
1985 To do so requires that we make it a function, so we do.
1986 * sparc-tdep.c (sparc_pc_adjust): New implem of PC_ADJUST.
1987 * utils.c (do_cleanups): Remove the current cleanup from the
1988 chain *before* calling it, in case error() is called from it.
1989 The result won't be pretty, but won't be an infinite loop either.
1991 Mon Aug 19 00:41:04 1991 Michael Tiemann (tiemann at cygint.cygnus.com)
1993 * dbxread.c (read_struct_type): Grok anon structs for C++.
1994 (vb_name, vptr_name): Null terminate these strings.
1996 Fri Aug 16 08:31:03 1991 John Gilmore (gnu at cygint.cygnus.com)
1998 Minor bug fixes from BSD Net2 gdb:
2000 * blockframe.c (get_prev_frame_info): If FRAME_CHAIN_COMBINE
2001 returns 0, there is no previous frame.
2002 * breakpoint.c (commands_command): If !from_tty, don't call
2003 input_from_terminal_p().
2004 * dbxread.c (record_misc_function): Speed up slightly.
2005 (compare_psymbols): Ditto.
2006 * infcmd.c (do_registers_info): Take a second argument to
2007 determine whether to print float registers. "info registers"
2008 does not do so anymore. "info all-registers" does, now.
2009 * mips-tdep.c, pyr-tdep.c (xxx_do_registers_info): Take second
2011 * tm-mips.h, tm-pyr.h (DO_REGISTERS_INFO): Pass second arg.
2012 * inflow.c (initialize_inflow): Set tflags_ours correctly.
2016 * breakpoint.c (bpstat_do_actions): Use a cleanup to restore
2017 executing_breakpoint_commands if we are interrupted by error.
2018 * coffread.c (init_lineno): Avoid problem with zero-sized linetab
2019 versus malloc/free. From: john@labtam.labtam.oz.au (John Carey).
2020 * core.c (solib_add_stub, core_open): Call SOLIB_ADD inside a
2021 catch_errors() so we can setup the frame regardless of whether
2022 the shared libs work.
2023 * ieee-float.c (double_to_ieee_extended): Get exponent from
2024 right place in little-endian systems. From John Carey.
2026 Thu Aug 15 18:43:57 1991 John Gilmore (gnu at cygint.cygnus.com)
2028 * main.c: Remove unused terminating_signals and catch_termination().
2029 (long_options): Terminate with a zero element.
2030 [Bugfix from Atsuo Kawaguchi <atsuo@hark86.harl.hitachi.co.jp>.]
2031 (gdb_readline): Make call-compatible with readline.
2032 (init_signals): Improve comments re vfork vs. signal.
2034 * utils.c (prompt_for_continue): Use new gdb_readline().
2035 If we prompt for continuation, we don't let CR repeat the previous
2036 command, once we get back to a prompt. It's too easy to keep
2037 hitting CR, expecting "--more--" prompts, and have some long
2038 command start repeating on you.
2040 Tue Aug 13 16:17:56 1991 John Gilmore (gnu at cygint.cygnus.com)
2042 * blockframe.c (frameless_look_for_prologue): Speed up by
2043 calling SKIP_PROLOGUE_FRAMELESS_P if it's defined.
2044 * tm-sparc.h (SKIP_PROLOGUE, SKIP_PROLOGUE_FRAMELESS_P):
2045 Define two variants, one faster.
2046 * sparc-tdep.c (sparc_frame_chain): Use target_read_memory
2047 and return zero, rather than giving an error.
2048 (setup_arbitrary_frame): Initialize the PC in the new frame.
2049 (skip_prologue): Add a second arg saying whether we're just
2050 checking for a frameless function or not.
2052 * core.c (core_open, core_close, core_xfer_memory): Move
2053 section table pointers and bfd* into the target_ops.
2054 (core_open): Allow errors in shared lib reading, etc.
2055 (core_files_info): Describe shared library sections.
2057 * exec.c (exec_open, exec_close, exec_xfer_memory, xfer_memory,
2058 exec_files_info, set_section_command): Move section table
2059 pointers and bfd* into the target_ops.
2060 (add_to_section_table): Add BFD to section table.
2062 * target.c (target_xfer_memory, target_info): Pass target to
2063 xfer_memory and target_info functions.
2066 * gdbcore.h: Move struct section_table.
2067 * target.h: New home of struct section_table.
2069 * solib.c (solib_add): New argument is the target_ops whose
2070 section list is to be added to, if any. Reallocate the
2071 sections in that target to add any that come from shared libs.
2072 (throughout) so_sections renamed to sections.
2073 (solib_xfer_memory): Deleted.
2074 * tm-sunos.h (SOLIB_ADD): Add target argument.
2075 (SOLIB_XFER_MEMORY): Delete.
2077 * core.c, exec.c, inftarg.c, remote-eb.c, remote-nindy.c,
2078 remote-vx.c, remote.c, target.c, target.h: Remove add_syms vector
2079 from target_ops. It's the same on all targets. Add two section
2080 pointers to target_ops.
2082 * stack.c (find_relative_frame): Dump ancient algorithm for
2083 "down", just use handy "next" pointers.
2084 (frame_command): Don't error if there is no stack; let user
2087 * inflow.c (new_tty_prefork, new_tty): New prefork routine
2088 modifies static state in the parent process; new_tty itself
2089 runs in the child and modifies the child's file descriptors
2090 to match the saved static state.
2091 * infrun.c (child_create_inferior): Call new_tty_prefork,
2094 * infptrace.c (child_xfer_memory): Add ignored target arg.
2095 * remote-eb.c (eb_xfer_inferior_memory): ''
2096 * remote-nindy.c (nindy_xfer_inferior_memory): ''
2097 * remote-vx.c (vx_xfer_memory): ''
2098 * remote.c (remote_xfer_memory): ''. Rename from
2099 remote_xfer_inferior_memory.
2101 * main.c (main): Only try to attach "corefile" argument if
2102 it starts with a digit.
2104 * symfile.c (symbol_reloading): New "set/show" variable.
2105 (symbol_file_add): Shorten message about symbol reading.
2106 (add_symbol_file_command): Merge with add_syms_addr_command,
2107 since this should work on all targets now.
2108 (stop_whining): Default to zero, to shut up complaints
2109 about bad symbol tables on many systems.
2110 (free_named_symtabs): Just exit unless symbol_reloading.
2112 * xm-sun3os4.h, xm-sun4os4.h: Define BROKEN_LARGE_ALLOCA,
2113 and add comment explaining shared library screw.
2115 * source.c: #if defined => #ifdef.
2117 Thu Aug 8 12:23:19 1991 John Gilmore (gnu at cygint.cygnus.com)
2119 * doc/gdbint.texinfo: Improve doc on porting to new OS's.
2121 Tue Aug 6 17:16:15 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
2123 * doc/rdl-apps.texinfo: provide default readline-appendix finder
2124 (doc/Makefile knows how to make one for local config)
2126 * Makefile.in: use doc/Makefile for doc targets
2128 * doc/Makefile: GDB documentation now has its own Makefile
2129 doc/refcard.tex: renamed from "gdbrc.tex"
2130 doc/.Sanitize: add Makefile; recognize renamed refcard.tex
2131 doc/gdbint.texinfo: add markup in "Cleanups" chapter
2134 Fri Aug 2 00:13:06 1991 John Gilmore (gnu at cygint.cygnus.com)
2136 * values.c (baseclass_addr): When reading target memory, use the
2137 length of the basetype, not the upper type. We've only malloc'd
2138 enough space for the basetype, leading to errors in free().
2140 * expprint.c (print_subexp): Print UNOP_MEMVAL of an OP_LONG that
2141 ends up as a function specially, since we know the actual type of
2142 the pointed-to address. This (somewhat) fixes display of
2143 expressions that include misc_function_vector names. Try `cond 1
2144 !strcmp("a","b")' then `i b'.
2146 * infrun.c: Move DO_DEFERRED_STORES from proceed() to resume().
2147 The child can be proceeded from inside wait_for_inferior in
2148 evaluating breakpoint conditions, and DO_DEFERRED_STORES was
2149 getting skipped in that case.
2151 * expprint.c (print_subexp): Use filtered output, since the
2152 subroutines we call use it, otherwise the output is horribly
2153 mangled, since output of wrappable stuff comes out late.
2155 * Makefile.in: Bump VERSION to 3.98.1
2157 * infrun.c (child_create_process): Use execlp to find the
2158 shell to exec our target program. This requires some fiddling
2159 with `environ' since there is no execlpe().
2161 Thu Aug 1 15:35:17 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
2163 * Makefile.in, doc/gdbrc.tex, doc/rc-* (new files):
2164 Minor rearrangement of refcard permits two new make targets--
2165 gdbrc.dvi DVI output for refcard, using CM fonts
2166 gdbrc.ps PostScript refcard, using PS fonts
2168 Wed Jul 31 16:46:21 1991 John Gilmore (gnu at cygint.cygnus.com)
2172 * TODO, Projects, WHATS.NEW, README: Update for gdb-3.98.
2173 * Makefile.in (gdb-all.texinfo): Avoid touching file if M4 dies.
2175 Wed Jul 31 16:35:58 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
2177 * doc/gdb.texinfo: last changes for release.
2178 Minor typo and formatting fixes; incorporated most fixes remaining from
2179 filed mail commenting on earlier drafts.
2181 Added warnings: pipes don't work in run command;
2182 conditions are converse of assertions;
2183 step over fn without debug info goes to next fn;
2184 vars may have "wrong" values near fn entrance, exit
2186 Added example from Kingston on printing repeated nonadjacent values
2188 Added explicit mention that in Emacs gdb mode C-c and C-z are like
2189 shell mode for signals
2191 Renamed "Stepping and Continuing" to "Continuing and Stepping" so it
2192 doesn't sound so much like its parent "Stopping and Continuing"; also
2193 moved entries on continue to top of section, so they don't get lost.
2195 Improved installation directions in appendix, added manual formatting
2198 Tue Jul 30 17:26:39 1991 John Gilmore (gnu at cygint.cygnus.com)
2200 * configure.in: Remove xm.h and tm.h even if we aren't linking
2201 new ones, so "./configure sun4; ./configure none" does the right
2202 thing. Assume that alldeps.mak and depend are already built in
2203 srcdir, and avoid running "make" (particularly "make depend",
2204 which involves "gcc") from inside configure. Build Makefile
2205 directly rather than building Makefile.conf first.
2206 * configure: Regenerate with above changes.
2207 * Makefile.in: Use $(BISON) to find bison. Roll VERSION
2208 to 3.98. Revise gdb.tar.Z procedure to produce a file
2209 called gdb-$(VERSION).tar.Z but which unpacks into a
2210 directory called "gdb". Move non-source files out of
2211 $(SFILES_SUBDIR). Pretty up alldeps.mak with comments.
2212 (depend): Don't try to do "gcc expread.y".
2213 (expread.o): Update dependencies by hand.
2215 Mon Jul 29 15:21:09 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
2218 Fixed a variety of small typos that prevented info from formatting
2219 cleanly; altered too-long heading for GPL Appendix, as discussed
2220 w/RMS; Changed date on cover to July 91.
2222 Fri Jul 26 13:20:02 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
2225 (1) Applied some fixes due to comments from Larry Breed (easier ones
2226 through chapsec 5.2)
2227 (2) Eliminated use of @footnote---had my doubts about it anyways, and
2228 it's broken in latest texinfo
2229 (3) Introduced *some* use of [] for optional arguments, where
2230 explanation is not simpler by listing cmd w arg and cmd w/out arg
2231 separately. Still not using @deffn.
2232 (4) Dropped in GPL-2. NOTE: one of GPL-2 or texinfo is broken; a
2233 couple of headings are too long. Need patches to texinfo or revision
2236 * Partial update to README (which still needs work for this
2237 release!): (1) use of configure corrected for new script,
2238 (2) "make gdb.dvi" and "make gdb.info" mentioned.
2240 Wed Jul 24 06:44:02 1991 John Gilmore (gnu at cygint.cygnus.com)
2242 * symtab.c (lookup_symbol): Don't complain right off about
2243 no debug symbols; use the misc function vector first.
2244 (list_symbols): Use misc function vector to find symbols
2245 that don't have debug info, and print them.
2246 (find_pc_symtab): Temporarily avoid fatal() when psymtab
2247 PC range doesn't match symtab PC range, as it does on the
2248 MIPS because our symtab reading isn't perfect.
2250 * dbxread.c (dbx_symfile_read): Make warning about
2251 "no debug symbols" slightly nicer.
2253 * source.c (select_source_symtab): If "main" symbol exists,
2254 but decode_line_spec can't find line info, don't just return
2255 a zero; try other source symtabs or give an error.
2257 * mipsread.c (parse_partial_symbols): Sort the psymtabs by
2258 their low addresses first, then rip through fixing high addrs.
2260 * ns32k-opcode.h (sfsr): Bugfix from Rune Nerg}rd,
2261 <runene@ifi.uio.no>.
2262 (NS32K_SVC_IMMED_OPERANDS): Reverse the #ifndef.
2264 Tue Jul 23 18:52:43 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
2266 * Minor, mostly mechanical, cleanup of doc subdir for clean
2267 makeinfo'ing and TeXing; also ensured gdb-all.texinfo (post-m4)
2268 and gdb.info (post- texinfo2 makeinfo) generated for distribution.
2270 Sun Jul 21 03:54:52 1991 John Gilmore (gnu at cygint.cygnus.com)
2272 Mostly MIPS and general symbol-reading fixups.
2274 * doc/gdbint.texinfo: Add documentation on symbol-reading
2277 * mipsread.c: Remove kludges around #include "ecoff.h".
2278 Remove redefinitions of a_magic, etc, no longer used.
2279 (parse_symbol, ): Convert "Internal:" printfs to complain()ts.
2280 Fix global overview comments to match symfile.c protocol.
2281 (mipscoff_new_init): Eliminate cur_hdr if we have one.
2282 (mipscoff_symfile_read): Eliminate unused code. Avoid
2283 sorting all the symtabs, when all we have read here is psymtabs.
2284 The symtabs are sorted as they are created anyway. Tell
2285 condense_misc_bunches whether we're mainline.
2286 (psymtab_to_symtab_1): Pass filename when recursing, to make
2287 stack trace more informative.
2288 (parse_partial_symbols): Assume cur_hdr as argument.
2289 (read_mips_symtab): Don't clobber cur_hdr, so it can be freed.
2290 Pass cur_hdr implicitly to parse_partial_symbols. Avoid checking
2291 the TYPE_NAME of char *, since that's done in symfile.c.
2292 (free_numargs, parse_symbol, add_symbol, add_block,
2293 shrink_linetable): Declare these fns void.
2294 (upgrade_type): Convert tree of if's to switch. Clean up
2295 bogus "off == 0" handling with a complaint. Avoid setting
2296 field bitpos and bitsize of array with lower and upper bounds.
2297 Check specified bitsize of elements against their actual type's
2298 bitsize, and complain if different. Complain about unknown
2300 (parse_fdr): Don't assume sizeof(char *) == sizeof (struct *).
2301 (psymtab_to_symtab_1): Print names of subsidiary files that
2302 are being read in. FIXME, we read far too many files. This code
2303 is not the problem, the problem is in parse_fdr where the psymtabs
2305 (cross_ref): Result should indicate that we used one aux entry
2306 normally, or two if we encountered a "next" entry. This used
2307 to leave the caller pointing at the wrong aux entry.
2308 (add_symbol): If overflowed cur_block, reallocate it larger,
2309 chase all pointers to it, and complain(), rather than clobber memory.
2310 (shrink_block): Use xrealloc rather than xmalloc-and-copy.
2311 (new_field): Only allocate one field initially, not two.
2312 Pull ++ out of macro argument. Simplify.
2313 (_initialize_mipsread): Avoid initialization of importd
2314 global_psymbols and static_psymbols.
2316 * symfile.c (psymtab_to_symtab): Depend on XXX_psymtab_to_symtab
2317 to properly set pst->symtab; avoid searching for it.
2318 (symfile_fns): Improve comments, add a FIXME.
2319 * dbxread.c: Update comments to reflect symfile protocol.
2320 (read_ofile_symtab, end_symtab): Return the symtab.
2321 (psymtab_to_symtab_1): Set pst->symtab.
2323 * coffread.c (coff_symfile_read): tell condense_misc_bunches
2324 whether we're mainline.
2326 * symfile.h (sym_fns): Remove unused sym_discard member.
2327 * coffread.c, mipsread.c, dbxread.c: Remove XXX_symfile_discard.
2329 * mtrace.c (mtrace): Take effect if mallwatch is set, even if
2330 the environment variable is not.
2331 * infcmd.c (finish_command): Use filtered printfs.
2332 * cplus-dem.c: Add struct tags to a few unnamed structs.
2333 * valops.c (value_coerce_array): Improve comments.
2334 * valprint.c (type_print_varspec_suffix): Print array size only
2335 if greater than zero.
2336 * m88k-tdep.c: Shift some lines left by one space, that had
2337 apparently been trashed at some point.
2338 * TODO: More things to do, a few got done.
2340 Thu Jul 18 22:46:05 1991 John Gilmore (gnu at cygint.cygnus.com)
2342 * symtab.h (LOC_EXTERNAL): Eliminate in favor of LOC_STATIC.
2343 (ldsymoff, ldsymlen, globals_offset, statics_offset): Improve
2345 * dbxread.c (read_dbx_symtab): LOC_EXTERNAL -> LOC_STATIC.
2346 * expread.y, findvar.c, symmisc.c: Ditto.
2347 * printcmd.c (address_info): Update printed forms of LOC_
2348 symbols. Elim LOC_EXTERNAL.
2349 (print_frame_args): Keep track of param stack offsets before
2350 re-looking up to find the local register param is kept in.
2352 * mipsread.c: Use <symconst.h> and <sym.h> rather than <syms.h>.
2353 Further integration of mipsread into gdb. Eliminate unused
2354 routines, duplicate declarations. Handle static symbols in
2355 psymtabs as well as external symbols. When reading symtabs,
2356 insert symbols into the correct block (global, static, or a local
2358 (read_mips_symtab, parse_partial_symbols): Don't pass useless
2360 (mipscoff_symfile_read): Don't call select_source_symtab.
2361 (parse_symbol): Use SYMBOL_VALUE_ADDRESS where appropriate,
2362 rather than SYMBOL_VALUE.
2363 (parse_external): Comment clobbering of top_stack.
2364 (parse_partial_symbols): Update comments. Allocate and parse
2365 static symbols as well as external symbols. FIXME, enum values
2366 are not handled in this pass, but should be. Inline new_psymbol.
2367 Use SYMBOL_VALUE_ADDRESS.
2368 (psymtab_to_symtab_1): Read symbols into global static block
2369 by default (until enter some function's local block context).
2370 (sort_blocks): Clean up STATIC_BLOCK as well as GLOBAL_BLOCK.
2371 (destroy_all_symtabs, new_psymbol): Eliminate, unused.
2373 * source.c (select_source_symtab): Select a source symtab
2374 from either the symtabs or, failing that, the psymtabs.
2375 (list_command): Update error message.
2376 (forward_search_command, reverse_search_command): Use getc, not
2377 fgetc, for speed. FIXME, add comment about buffers that die if
2378 overrun by long line.
2380 * values.c (unpack_field_as_long, modify_field): Avoid shifting
2381 by an entire word, which is not portable, if we have a 32-bit
2382 field. (Code in dbxread.c already turns such bitfields, if
2383 aligned, into ordinary ints, but fixing this will help for other
2384 symbol formats and for future changes.)
2385 * core.c (core_open): Handle ANSI const brain death.
2386 * utils.c (vprintf): Fix varargs typo.
2388 Sun Jul 14 00:42:53 1991 John Gilmore (gnu at cygint.cygnus.com)
2390 * findvar.c (find_var_value): Handle &function better.
2391 * TODO: Document work needed on &fn and &array.
2392 * printcmd.c (print_address_symbolic): New arg is the prefix
2393 to print if a name is printed.
2394 (print_address_demangle): Honor "set print address" now.
2395 Use new arg above to improve spacing of output.
2396 * valprint.c (val_print): When printing function pointers,
2397 print symbolic form too.
2398 * breakpoint.c (breakpoint_1): Use new print_address_symbolic.
2400 Mon Jul 8 19:02:46 1991 John Gilmore (gnu at cygint.cygnus.com)
2402 * core.c (memory_error): Reword error msg to mislead less.
2404 * mips-pinsn.c (print_insn_arg 'd'): Print $ with reg name.
2406 * mipsread.c (read_mips_symtab, read_the_mips_symtab,
2407 parse_partial_symbols): Use newer BFD internals (external_filehdr
2408 and external_aouthdr), byte-swap the fields that we care about
2409 before using them, and make the file header data local to
2410 read_the_mips_symtab rather than global.
2412 Sat Jul 6 01:34:15 1991 John Gilmore (gnu at cygint.cygnus.com)
2414 * ns32k-opcode.h (movmw, movmd): Fix opcodes. Bug fix
2415 from Rune Nerg}rd <runene@ifi.uio.no> on 5 Jul 1991.
2417 * main.c (command_line_input): Flush stdout and stderr
2418 before every call to readline. This reportedly fixes a bug
2419 that comes up in Sys V running emacs-gdb and/or xxgdb,
2420 when stdin/out are pipes or sockets.
2422 Thu Jul 4 14:47:06 1991 John Gilmore (gnu at cygint.cygnus.com)
2424 * configure.in, Makefile.in: Avoid rebuilding "depend" as much.
2425 Avoid declaring Makefile dependencies, because GNU Make stupidly
2426 tries to update it if we do.
2428 * coffread.c: Revise for minor changes to bfd internal coff
2431 * configure: If -template= is given a relative path, make it
2432 absolute before recurring in subdirectories.
2434 * configure, configure.in, Makefile.in: Install "configure" script
2435 as replacement for config.gdb.
2436 * config.gdb, Makefile.dist, Makefile.sdir: Remove
2437 * README: Update for configure, mostly. FIXME.
2439 * Add dec3100 as equivalent to littlemips. Indicate in all host &
2440 target config files that they are for the host. When the lines
2441 get copied into the Makefile, this makes it more obvious what's
2444 Mon Jun 24 23:49:07 1991 John Gilmore (gnu at cygint.cygnus.com)
2446 * sparc-opcode.h (trap opcodes): Avoid leading spaces or
2447 tabs, which end up in the disassembler output inadvertently.
2449 Wed May 29 23:01:03 1991 John Gilmore (gnu at cygint.cygnus.com)
2451 Make it compile cleanly in an ANSI GCC2 environment.
2453 * blockframe.c: <stdio.h>
2454 * cplus-dem.c: free takes a void *, ifdef __STDC__
2455 * dbxread.c (read_huge_number): avoid gcc2 bug hoisting calc of
2457 * defs.h (alloca): Avoid doing anything if alloca already def'd.
2458 * stddef.h, stdlib.h: Remove these files.
2459 * symtab.c: Avoid declaring qsort, close.
2460 * symfile.c: Avoid declaring close.
2461 * utils.c (vprintf): Declare "ap" arg as proper va_alist.
2462 * sparc-tdep.c: Avoid including lots of Sun-host-specific files.
2464 Assorted other changes.
2465 * dbxread.c: include "libaout.h", not "liba.out.h".
2466 * printcmd.c (print_frame_args): Set recurse properly for
2467 indentation of struct and array parameters.
2468 * valops.c (value_cast): Allow cast to void.
2469 * infrun.c (resume): If NO_SINGLE_STEP, call machine dependent
2470 single_step() in a target-independent fashion.
2471 * sparc-tdep.c (single_step): Don't call ptrace ourselves, just
2472 set up to be ready to continue. This makes us target independent.
2473 * infptrace.c (child_resume): Remove call to single_step; now
2474 can single step a SPARC target of any kind.
2476 Wed May 22 18:18:24 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
2478 * Makefile.dist, doc/gdb.texinfo, doc/*-m4.texinfo: split up GDB
2479 docn into separate sections---basically chapters, plus two loose
2480 pieces that can be configured to go in different places. This
2481 allows GNU m4 to preprocess the manual without coredumping.
2483 * Makefile.dist: tell TeX where to find texinfo.
2485 Mon May 20 12:15:04 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
2487 * Makefile.dist, doc/gdb.texinfo: respectively create, and use,
2488 the new target "rdl-apps.texinfo" which captures the Makefile
2489 variable that records where to find the Readline libraries.
2491 Sun May 19 05:36:59 1991 John Gilmore (gnu at cygint.cygnus.com)
2493 * tahoe-pinsn.c: #include "tahoe-opcode.h", not "opcode.h".
2494 * tm-tahoe.h (FIX_CALL_DUMMY): Ignore more parameters.
2495 * defs.h (const, volatile): Only define if not already defined.
2496 * Makefile.dist (gdb.tar.Z): Create doc subdir w/out CVS/RCS crud.
2498 * README: Update for release 3.95.
2499 * config.gdb: Don't create readline dir in subdir builds.
2500 * main.c: Include with "..." form for non-system include files,
2501 so "gcc -MM" for "make depend" works.
2502 Include readline files with "...h" rather than <readline/...h>.
2503 * mipsread.c: Include "ecoff.h" rather than "intel-coff.h".
2505 * coffread.c: Undo minor damage done by Rich Pixley. Use
2506 different internal and external representations of COFF
2507 data structures. Use new BFD routines for swapping them in and
2509 * symfile.c (free_named_symtabs): Avoid freeing file names that
2510 are null or empty. Old i960 tools seem to produce files that
2511 claim to have empty names, causing each successive file read
2512 to blow away the previous one.
2513 * sparc-xdep.c (deferred_stores): Repair minor damage by Rich.
2514 Move deferred_stores to top of file, but don't separate its
2515 #define's from its variable. Add commentary.
2516 * Makefile.dist: Fix Rich damage; undo "configure" changes in
2517 favor of keeping the (working) config.gdb. Move readline
2520 Fri May 17 12:49:56 1991 Per Bothner (via gnu at cygint.cygnus.com)
2522 * dbxread.c (read_struct_type): Try to handle g++ version 1 MI
2524 * infptrace.c (fetch_registers): no result, since now void.
2525 * tconfig/news: target depends on m68k-tdep too.
2527 Fri May 17 14:40:14 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
2529 * Makefile.dist: added readline/inc-*.texinfo to dependencies for
2532 * readline/inc-history.texinfo, readline/inc-readline.texinfo:
2533 applied various small fixes due to or inspired by RMS comments
2535 * doc/gdb.texinfo: finished using all RMS comments, save those for
2536 appendices on readline and cmd history (which are in other source
2539 Thu May 16 18:06:05 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
2541 * doc/gdb.texinfo: (1) Updated w/ref to RMS comments through
2542 chapter 9; (2) documented 'break' command's menu mode for
2543 overloaded names, in response to hgs problem report C++ p-31
2545 Wed May 15 11:02:48 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
2547 * doc/gdb.texinfo: (1) better introductory example; (2) more
2548 consistent use of @code, @samp, @file, @kbd throughout; small
2549 cleanups to first three nodes; (3) new "Contributors" node;
2550 (4) Appendix, Renamed Commands; (5) divert specialized startup
2551 instructions to "Targets" chapter for generic manuals, while
2552 leaving them up front for manuals specific to specialized
2553 environments; (6) apply fixes from RMS comments through chapter 4.
2555 * pretex.m4: modify explanatory text slightly (and redefine
2556 "regexp") to keep GNU m4 from complaining. (It still crashes
2557 later, but one step at a time...)
2559 Wed May 15 10:32:12 1991 John Gilmore (gnu at cygint.cygnus.com)
2561 * readline/readline.c (update_line): Avoid dereferencing a pointer
2562 before comparing it to its bounds. Saber caught this.
2563 (init_terminal_io): Don't set BC from the "pc=" termcap variable,
2564 and only set PC if tgetstr returned non-null. Saber caught this.
2566 Tue May 14 16:29:53 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)
2568 * Makefile.dist: put gdb.dvi stuff (updated to use M4 preprocessor
2569 stuff for config manual) here where it counts; updated
2570 to use new subdir structure (gdb/doc/).
2572 * Makefile: generated from above via
2576 * gdbint.texinfo: added instructions on generating gdb.info* files
2577 locally for release. These are ordinary info
2578 files, formatted from gdb.texinfo (via gdb-all.texinfo, see
2579 Makefile)---but due to use of texinfo 2, can't count on makeinfo
2580 to generate these, so we distribute them already formatted.
2582 * gdb.texinfo: included full Info node and menu crud (as generated
2583 by C-u M-x texinfo-master-menu using the texinfo-2 elisp code).
2585 * Makefile: updated "gdb.dvi" target to use M4 preprocessor;
2586 put in comments-for-future gdb.info target (one day makeinfo will
2589 Tue May 14 13:51:36 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)
2591 * gdb.texinfo: Updated to include new or old undocumented
2592 commands, at least the following (perhaps some others I forgot to
2593 record): info f, info float, info path, info program, info s, info
2594 set, info source, info terminal, info types, info user, set/show
2596 Also covered all recent GDB command renames for v4.
2598 Mon May 13 14:57:46 1991 John Gilmore (gnu at cygint.cygnus.com)
2600 * mipsread.c: Rather than keeping count of how many symtabs
2601 and psymtabs we have, for sorting purposes, count them when
2602 we need to sort. This fixes bug in rereading of symbol tables.
2604 Fri May 10 15:43:33 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)
2606 * infcmd.c: renamed "info path" to "show paths"

2621 symtab.h, target.c, target.h: Lint.
2622 * core.c: setup and select frame after reading shared libs,
2623 else reading shared libs will clobber them. Lint.
2624 * utils.c (error): Force out any buffered wrap text.
2626 Fri May 3 22:01:56 1991 John Gilmore (gnu at cygint.cygnus.com)
2628 * remote.c: Remove decls of memory_insert_breakpoint
2629 and memory_remove_breakpoint, no longer used. (Suggestion of
2632 * Makefile.dist: use ${subdir} in paths of BFD and LIBIBERTY,
2633 to make it easier to interface to "configure"'d libraries.
2635 Fri May 3 13:10:01 PDT 1991 Roland Pesch (pesch at fowanton.cygnus.com)
2637 * valprint.c: introduce "set p", "set pr", "show p" and "show pr" as
2638 aliases for set/show print.

2768 Remove from_tty arg to mod_path.
2769 Put symfile_bfd in {coff,dbx}read.c not symfile.h.

3189 * dbxread.c (read_dbx_symtab): Allow N_SOL to cleanly take us back
3190 to the main file, as well as to include files. Also, put global
3191 functions into the global psymtab, to make "i fun" work.
3192 (end_psymtab): Free named symtabs and psymtabs for a file, once a
3193 new psymtab for it has been read.
3194 * coffread.c (end_psymtab): Free named symtabs and psymtabs for
3195 a file, once a new symtab has been read for it.
3196 * mipsread.c: FIXME. We need to do the same for MIPS, but it
3197 looks harder to determine the top-level block before it's been
3198 queued to the psymtab list.
3200 * symfile.c (symbol_file_add): Use filtered printing and wrap it.
3201 If we have wiped out any old symbol tables, clean up at end of

3216 * symtab.c (list_symbols): Process the first symbol of the
3217 static psymbols list.
3218 (types_info): Restore this function from its untimely #if 0.
3219 It's not perfect, but it is better than nothing.

3231 * symmisc.c (free_named_symtab): Make it work, in its current

3235 * symfile.h: free_named_symtab now returns an int.
3237 Mon Apr 8 23:57:43 1991 John Gilmore (gnu at cygint.cygnus.com)

3240 is the first symbol read, even if not mainline.
3241 (dbx_psymtab_to_symtab): symfile might be zero, cope.
3242 * exec.c (exec_ops): Add_syms_addr is valid in our tvec.
3243 (set_section_command): New command ("section xxx yyy" -- should
3244 be renamed to "set section xxx yyy" FIXME) which sets the
3245 base address of a section of the exec file, overriding the
3246 virtual address that BFD reports.
3248 Fri Apr 5 17:14:39 1991 John Gilmore (gnu at cygint.cygnus.com)
3250 * exec.c: Add add_syms_addr_command to exec_ops, so you can

3255 * tm-i386v.h (FLOAT_INFO): Don't define it, since the code
3256 for printing the float info is host-dependent, not
3257 target-dependent. FIXME.
3258 * i386-pinsn.c: Move #includes to top, remove useless ones.
3259 * i386-tdep.c: Don't bother including <.../reg.h> since we
3260 don't use it (and it doesn't exist on host systems).
3262 * ieee-float.c (ieee_extended_to_double): Convert NaN to Inf.
3263 Convert negative numbers properly.
3264 (ieee_test): Make numbers really random; fix format arg.
3266 * infcmd.c (attach_command, detach_command): Don't repeat on CR.
3267 * core.c (core_detach): Unpush core_ops, which might not be on
3268 top. We used to just pop the top, which broke things. Don't
3269 need dont_repeat() any more.
3270 (core_file_command): Psst! Don't repeat it.
3271 * remote-nindy.c (nindy_detach): Don't need dont_repeat() now.
3272 * expprint.c (print_subexp): Avoid switch fallthru on
3273 BINOP_ASSIGN_MODIFY, so we can print += and such.
3274 * frame.h: Fix typo.
3275 * inflow.c (kill_command): After killing inferior, print our
3276 current frame in the core file, if we have one.
3277 (generic_mourn_inferior): When inferior dies, either select
3278 the current frame (in the new target, e.g. core file), or
3279 set both the current and selected frames to NULL.
3281 Changes from Peter Schauer.
3283 * infptrace.c: Avoid <sys/ptrace.h> on USG.
3285 * Make all file names fit in 14 characters (sigh and damn!):
3286 mv hp300hpux-xdep.c hp300ux-xdep.c
3287 mv symmetry-xdep.c symm-xdep.c
3288 mv symmetry-tdep.c symm-tdep.c

3293 mv gdb-int.texinfo gdbint.texinfo
3294 mv remote-sa.m68k.shar rem-m68k.shar
3295 mv remote-multi.shar rem-multi.shar
3296 * Makefile.dist, README, config.gdb, convex-pinsn.c,
3297 tconfig/symmetry, tconfig/vxworks960, tconfig/vxworks68,
3298 xconfig/hp300hpux, xconfig/symmetry: Change names to shorter
3301 * command.c (user_info_1, user_info): New command for listing
3302 the user-defined commands.
3304 Wed Apr 3 15:00:26 1991 John Gilmore (gnu at cygint.cygnus.com)
3306 * dbxread.c (really_free_pendings): Clear file_symbols
3307 and global_symbols after freeing them; otherwise, running
3308 this function twice (if it appears twice on the cleanup
3309 chain), we try to free things twice.
3311 * dbxread.c (read_dbx_symtab): Calculate end_of_text_addr
3312 based on text_addr (the address of text in core), not on addr (the
3313 offset between text in the .o file and in core). This change
3314 is from Peter Schauer.
3316 * main.c: Define ALL_CLEANUPS as a cast of zero.
3317 (return_to_top_level): Use it.
3318 (main): Do all cleanups after each command run as part
3319 of the gdb startup sequence. Also do all cleanups before
3320 entering the command loop, and every time we exit the command
3321 loop and reenter. Before, the cleanups from the startup sequence
3322 were being left undone until the first error!
3323 (command_loop): Rename do_nothing cleanup to command_loop_marker
3324 so we can see it easily when examining the cleanup chain.
3325 (init_signals): Add another do_nothing for signal handling.
3326 (quit_command): Only try to kill target if it has execution.
3327 Problems in the target stack got us into a state where
3328 inferior_pid was nonzero but none of the targets had execution.
3329 In this state you couldn't exit gdb.
3331 * dbxread.c: Two changes from Peter Schauer.
3332 (echo_command): Fflush output after an echo command.
3333 (show_history): Pass all args to cmd_show_list.
3335 * utils.c (init_malloc): Call mtrace to turn on tracing
3336 if the environment variable MALLOC_TRACE is set to a file name.
3337 * mtrace.c: Add source file which provides a log of every malloc,
3338 free, and realloc to a trace file.
3339 * mtrace.awk: Add source file which analyzes the trace file.
3340 * Makefile.dist (GNU_MALLOC, MALLOCSRC): Add mtrace.{c,o,awk}.
3341 (VERSION): Roll to 3.94.3.
3343 * breakpoint.c (breakpoint_1): Add a space to "i watch" output.
3344 (check_duplicates): Don't bother with watchpoints.
3345 (set_raw_breakpoint): Comment about danger of this routine.
3346 (watch_command): Parse and eval all args before calling
3349 * solib.c (find_solib): Avoid error in referencing memory to
3350 see if any more shared libraries have been added. This is
3351 particularly useful if the target has terminated. Bug reported
3354 Changes from Peter Schauer <pesrem@regent.e-technik.tu-muenchen.de>
3355 in bringing up 3.94.2 on the Sun-3.
3357 * Makefile.dist: Include CFLAGS in rule for cplus-dem.o.
3358 * breakpoint.c (enable_breakpoint): Check for valid watchpoint
3359 expression (in scope) before reenabling watchpoint.
3360 * signame.c (init_sigs): Add missing declaration of i, fix
3361 sys_siglist declaration.
3362 * source.c (list_command): Fixed range computation to use
3364 * stack.c (backtrace_command): Do not allow command if target has
3365 no stack, print informative error message.
3366 * target.c (target_command): Do not write into command line
3367 because this fails if the target command is used in a user defined
3368 command. [This change was enhanced by gnu to support any-
3369 unique-prefix matching on target names.]
3370 * valops.c (value_struct_elt): Avoid infinite loop on an
3371 erroneous attempt to print the member of function (try p main.p).
3373 Mon Apr 1 17:05:45 1991 John Gilmore (gnu at cygint.cygnus.com)
3375 * expread.y (name_no_typename): Avoid reduce/reduce errors
3376 caused by ambiguity in handling NAME_OR_INT and NAME_OR_UINT.
3377 Since the GDB parser really doesn't use name_no_typename in a
3378 name-only context, the parser can't tell the diff between
3379 names and numbers here. Avoid allowing a name_no_typename
3380 to be a NAME_OR_*INT to resolve the conflict.
3382 Sun Mar 31 20:12:07 1991 John Gilmore (gnu at cygint.cygnus.com)
3384 Bugfixes from Mark Fox (markf@wrs.com) (test=testField.c):
3386 * valprint.c (val_print_fields): bitfield printing didn't handle
3387 byte order. Indirect through a few more fns to cope.
3389 * values.c (modify_field): also cope with byte order.
3391 Sat Mar 23 10:02:21 1991 John Gilmore (gnu at cygint.cygnus.com)
3393 Cleanup for release 3.94.2:
3395 * Makefile.dist: Pull REMOTE_OBS. Fix saber includes for BFD
3396 include files. Roll version to 3.94.2.
3398 * coffread.c (init_stringtab): Read length into unsigned char
3399 array before swapping; don't assume 32-bit longs.
3401 * target.c (target_info): Don't bother with get_sym_file, just use
3402 the symfile global variable.
3403 * symtab.h, symfile.c (get_sym_file): Delete it.
3405 * dbxread.c (dbx_symfile_init): Don't depend on long == 4 bytes.
3406 (define_symbol): Set symbol line number to 0 if not gcc-compiled.
3407 (read_type): Replace one more error() with complain().
3409 * mipsread.c (parse_partial_symbols): Replace printf with complain.
3411 * i960-tdep.c: Fix copyright attribution.
3413 * config.gdb: Quote all backquotes in doublequotes. You can
3414 quote me on that. BSD 4.4 shell found this one.
3416 * infptrace.c (throughout): The third argument to ptrace is an
3419 * infrun.c (wait_for_inferior): When program has terminated, we
3420 have to call target_terminal_ours before we pop that target off
3421 the stack (e.g. before a call to target_kill or
3422 target_mourn_inferior). This fixes problem where a program
3423 terminates, then GDB stops for (tty output) and you have to type
3424 "fg" to the shell to resume it. FIXME: This code for what to
3425 do after termination really should be in normal_stop instead.
3427 * gdbcore.h (read_memory_check): Change declaration; it changed
3430 * terminal.h: Include <sgtty.h> before <sys/ioctl.h>, since in BSD
3431 4.4 prereleases, this avoids a bug in their sgtty compatability
3433 * remote.c: Use terminal.h rather than hand-rolling the same.
3435 * signame.c, signame.h (psignal): Arg is unsigned, not int.
3436 * utils.c (strsave, strstr): Fix arg types.
3437 * valprint.c (val_print): lint
3439 MIPS symbol table support from Per Bothner:
3441 * symfile.c (symtab_fns): Remove initializer table that needs to
3442 be hacked for each new symbol file format supported.
3443 (add_symtab_fns): New function, chains symbol table
3444 handlers into the global list.
3445 (symfile_init): Search this list.
3446 * symfile.h: Add next pointer, declare add_symtab_fns.
3447 * coffread.c (_initialize_coffread): Call add_symtab_fns.
3448 * dbxread.c (_initialize_dbxread): Call add_symtab_fns.
3450 * mipsread.c (psymtab_to_symtab_1): return void instead of (struct
3451 symbol *). Thus, we no longer need the hack to trash
3452 pst->filename. Good, since that hack confused code in symfile.c!
3454 (reorder_symtabs, destroy_all_symtabs): Removed static
3455 all_symtabs, which was used to qsort symtabs in reorder_symtabs.
3456 Instead, the latter now uses a temporary array (stack-allocated
3457 from an obstack, and then freed).
3459 (parse_symbol): Added a hack to fix up BLOCK_{START,END} if they
3460 haven't been set in the outermost stBlock of a procedure. This was
3461 a problem with f77 binaries on Ultrix 4.?.
3463 (new_symtab, new_symbol, new_type): Continue changing code to use
3464 obstacks more and otherwise conform to dbxread internal style.
3465 Made the free_code of symtabs be free_linetable (as in dbxread)
3466 instead of free_contents. This implies memory leaks when reading
3467 a new symbol table, until the conversion is finished. Did change
3468 (struct symbol) and (struct type) to be allocated on the
3469 symbol_obstack. Blocks and blockvectors are among the things
3472 * mipsread.c (parse_partial_symbols, parse_fdr): It hasn't been
3473 tested much, but it solved one problem (reported by Meissner), and
3474 cleans up some other things. The problem happened when an
3475 included file contains actual code (functions) and not just
3476 definitions. The mips coff is a little inconvenient there, since
3477 it may cause a procedure to be mapped to the wrong psymtab.
3479 * mips-tdep.c (heuristic_proc_desc): Minor cleanup.
3480 * mips-xdep.c (fetch_core_registers): Minor cleanup. FIXME,
3481 this will need work for the new core paradigm.
3483 Opcode patches from the net:
3485 * mips-opcode.h: fix incorrect disassembly of the mfc1, cfc1, and
3486 ctc1 instructions. Also, the cvt.d.w and cvt.s.w instructions were
3487 missing altogether - they are added here. From Bruce Bauman.
3488 * mips-opcode.h: The low mask for C0 instructions was too small.
3489 From Garrett Lau. I modified the fix to check the entire 32-bit
3492 * ns32k-opcode.h: Fix opcodes for deiw and deid. From Bruce
3495 Thu Mar 21 12:56:46 1991 John Gilmore (gnu at cygint.cygnus.com)
3497 Roll in changes from Per Bothner (Tue, 25 Sep 90 11:11:04):
3499 * dbxread.c (read_type): Pointer subtraction (value_sub in
3500 valarith.c) sometimes failed because the types of the
3501 pointers being subtracted were not identical.
3502 These differed because dbxread.c was allocating pointer types
3503 using dbx_alloc_type+smash_to_pointer_type instead of
3504 lookup_pointer_type. I failed to find a justification for the
3505 former, so I changed it to use the latter. Similarly, I
3506 replaced smash_to_function_type by lookup_function_type,
3507 and smash_to_reference_type by lookup_reference_type.
3509 * mipsread.c (parse_symbol, upgrade_type, parse_procedure,
3510 _initialize_mipsread): corresponding changes.
3512 * symtab.c (smash_to_{pointer,reference,function}_type): eliminate.
3514 * source.c (mod_path): Do tilde_expand on each component of the path,
3515 rather than on the (list of) paths as a whole.
3516 (print_source_lines): Set first_line_listed in addition to
3517 current_source_symtab and current_source_line. If the source was
3518 not findable, after a "dir" command to fix the problem,
3519 a "list" would get the wrong lines.
3521 While I was there... (gnu):
3523 * dbxread.c (read_type): Change error to complaint.
3525 Thu Mar 21 12:56:46 1991 John Gilmore (gnu at cygint.cygnus.com)
3527 First attempt at detailed understanding of symbol table memory alloc.
3529 * dbxread.c (dbx_symfile_read): Free our string table if we
3530 aren't the mainline. Free the "info" struct since we're done with
3532 (init_psymbol_list): Free any previously allocated psymbol lists.
3533 (): FIXME: Should realloc-down the psymbol lists when done reading
3534 the main symbol file?
3536 * symmisc.c (free_symtab): Free fullname field too.
3538 * xm-hp300hpux.h (USG): #undef then #define so Makefile can -D.
3539 (REGISTER_ADDR): Make result type unsigned int.
3541 * xconfig/{i386*,hp300hpux,altosgas,altos}: All config files that
3542 define REGEX must also define REGEX1 (its dependency).
3544 Tue Mar 19 21:28:57 1991 John Gilmore (gnu at cygint.cygnus.com)
3546 * tconfig/i960: No longer works, points you at vxworks960 or
3549 * xgdb.c, XGDB-README: Remove file. Users can get the much
3551 * Makefile.dist: Remove all trace of xgdb.
3553 * breakpoint.c (breakpoint_1): Pass demangle arg to
3554 print_address_symbolic.
3555 (clear_breakpoints): Remove unused function.
3556 (breakpoint_re_set_one): Guts of breakpoint_re_set.
3557 (breakpoint_re_set): Use catch_errors to do them all anyway.
3559 * gdb-int.texinfo (Host versus Target): Add section on what is
3560 a "host" feature versus what is a "target" feature.
3562 * infcmd.c (path_command, path_info): Handle the PATH variable
3563 (object search path) as conveniently as the source search path.
3564 * environ.c (set_in_environ): Set some vars in GDB's environment,
3565 in addition to the child's. PATH, G960BASE, G960BIN for starters.
3566 * source.c (mod_path): New function, from guts of
3567 directory_command, modifies a path. Used by path_command.
3568 (directory_command): Call it.
3569 * defs.h (strsave): Declare.
3571 * utils.c (sevenbit_strings): Add new printing option.
3572 (printchar): Use it.
3573 (strsave): Provide this handy helper routine.
3574 (set_width_command): Rename set_screen_width_command.
3575 (_initialize_utils): "set screen-width" => "set width";
3576 "set screen-height" => "set height"; add sevenbit-strings.
3578 * infcmd.c (do_registers_info): Print floating point registers
3579 in raw hex as well as float format, regardless of whether it is
3580 a "virtual" convertible register.
3581 * tm-sparc.h (PRINT_REGISTER_HOOK): Print every pair of float
3582 regs as a double, just in case it's being used that way.
3583 * values.c (unpack_long): Comment on array/function coercion.
3584 (unpack_double): Argument is in target byte order now. For
3585 integer arguments, just call unpack_long and float the result.
3586 * m68k-tdep.c: include defs.h for "const" handling.
3587 * remote-nindy.c: Use ieee-float stuff.
3588 (nindy_fetch_registers): Unpack double regs to host double, then
3590 (nindy_store_registers): Pack extendeds to host double, flip
3591 around by misusing unpack_double, send as target double.
3593 * tm-vxworks68.h (FRAME_CHAIN): Handle current frame pointer of
3594 zero, as when stopped at the first instruction of a process.
3596 * blockframe.c: Fix filename in comment (param.h => tm.h).
3597 * sparc-tdep.c (skip_prologue): More explicit nudging comments.
3598 * tm-68k.h: Fix typos.
3600 Fri Mar 15 01:09:34 1991 John Gilmore (gnu at cygint.cygnus.com)
3602 Changes from a bringup on the DEC Vax under Ultrix 4.0.
3604 * coredep.c (fetch_core_registers): Pass end-address of register
3605 section to register_addr as expected. Don't call supply_register
3606 if we'd just pass it garbage.
3608 * dbxread.c (read_dbx_symtab): Skip N_NSYMS on Ultrix.
3610 * exec.c (xfer_memory): Use boolean xfer_fn result, not int.
3612 * target.c (push_target, target_info): Cast enums to int for < or
3615 * stack.c (print_frame_info): Identify source file & line
3616 even if we can't print it.
3618 * xm-vax.h (MISSING_VPRINTF): No longer missing in Ultrix V4.0.
3620 Sat Mar 9 10:08:20 1991 John Gilmore (gnu at cygint.cygnus.com)
3622 Clean up IEEE floating point support.
3624 * ieee-float.h: New file.
3625 * ieee-float.c: Write real routines to convert between host
3626 doubles and various target IEEE extendeds.
3627 * m68k-xdep.c: Eliminate assembler code for extended floats.
3628 * xconfig/{3b1,altos,altosgas,hp300bsd,isi,news,news1000,sun2os3,
3629 sun2os4,sun3,sun3os3,sun3os4}: Eliminate use of m68k-xdep.o.
3630 * tm-i960.h, tm-68k.h (REGISTER_CONVERT_TO_VIRTUAL,
3631 REGISTER_CONVERT_TO_RAW): Use ieee_extended_to_double and
3632 double_to_ieee_extended.
3633 * i960-tdep.c: Define ext_format_i960.
3634 * m68k-tdep.c: Define ext_format_68881.
3635 * sparc-tdep.c: Define ext_format_sparc, though unused.
3636 * Makefile.dist (HFILES): Add ieee-float.h.
3637 * inftarg.c: #include "ieee-float.h" for the REGISTER_CONVERT
3640 Obsolete the "coffstrip" program in favor of using BFD's strip.
3642 * nindy-share/coffstrip.c: Remove file.
3643 * nindy-share/nindy.c (coffstrip): Routine to run bfd_strip.
3644 * Makefile.dist: Remove references to nindy-share/coffstrip.c.
3645 * tconfig/nindy960: Remove reference to coffstrip.o.
3647 * Makefile.dist: Roll version number to 3.94.1 (not yet final).
3649 Wed Mar 6 09:56:45 1991 John Gilmore (gnu at cygint.cygnus.com)
3651 * symfile.h: Add symfile_bfd, common between dbxread and coffread.
3652 * dbxread.c: Remove static symfile_bfd.
3653 * infcmd.c (do_registers_info): Add PRINT_REGISTER_HOOK, though
3655 * inftarg.c (child_detach): Pop the child_ops vector if the
3656 detach is successful.
3657 * remote-nindy.c (nindy_create_inferior): Don't push a new
3658 nindy_ops since nindy uses the same one for execution and memory
3660 * core.c (core_ops): Use child_attach and child_create_inferior
3661 rather than default attach and create_inferior functions.
3663 Handle floating point registers in core files.
3665 * sparc-xdep.c (fetch_core_registers): Rewrite for float support.
3666 * sun3-xdep.c (fetch_core_registers): Rewrite for float support.
3667 This version untested since BFD doesn't yet support sun3 core
3669 * hp300hpux-xdep.c: Rewrite fetch_core_registers to new calling
3670 conventions. Fix comments and style. This version has not
3671 been compiled yet, since we have no HP inhouse.
3672 * core.c (get_core_registers): Look for two sections, ".reg"
3673 and ".reg2", and pass both to fetch_core_registers sequentially.
3675 Revise directory path yet again.
3677 * source.c (forget_cached_source_info): Not static any more.
3678 (init_source_path): New default source path is "$cdir:$cwd".
3679 (dir_command): Handle variable arguments ($cdir, $cwd).
3680 (source_info): Print "Compilation directory" rather than
3681 "Originally compiled in" to remind people of $cdir.
3682 (openp): If the path contains $cwd, use current directory.
3683 (open_source_file): If compilation directory is known, replace
3684 first $cdir in path with the compilation directory.
3685 (print_source_lines): Even if we can't print the lines, set the
3686 current symtab and line for future commands like "info source" or
3687 "breakpoint". Also, error message now contains the file name,
3688 line number, and file access error message.
3689 (_initialize_source): Fix help text to describe changes.
3690 * main.c (cd_command): Forget cached source info when we chdir.
3691 * utils.c (strstr): Add simple implementation.
3693 Tue Mar 5 01:41:40 1991 John Gilmore (gnu at fowanton.cygnus.com)
3695 * coffread.c (read_one_sym, init_linetable, init_stringtab):
3696 Byte-swap COFF symbol tables if necessary when reading them in.
3697 Use complain() to replace error message in one spot. Needs
3698 corresponding change in bfd/coff-code.h to make some symbol
3699 swapping routines non-static.
3701 Mon Mar 4 00:53:40 1991 John Gilmore (gnu at cygint.cygnus.com)
3703 Merge changes from Eirik Fuller, for UTek.
3705 * defs.h (errno): Add declaration.
3706 * altos-xdep.c, arm-xdep.c, convex-xdep.c, gould-xdep.c,
3707 hp300hpux-xdep.c, infrun.c, inflow.c, infptrace.c, i386-tdep.c,
3708 i386-xdep.c, pyr-xdep.c, mips-xdep.c, remote-eb.c, remote-nindy.c,
3709 remote-vx.c, source.c, standalone.c, stuff.c, sun386-xdep.c,
3710 symmetry-tdep.c, symmetry-xdep.c, umax-xdep.c, utils.c: Eliminate
3711 declarations of errno.
3713 * remote-eb.c: Define B19200 and B38400 as EXTA and EXTB.
3715 * remote-vx.c: Include <sys/time.h> for UTek; Sun gets it via
3716 <rpc/rpc.h> and <rpc/types.h>.
3718 Sat Mar 2 15:47:55 1991 John Gilmore (gnu at cygint.cygnus.com)
3720 * i960-tdep.c (examine_prologue): Add new argument limit,
3721 which stops the scan at the end of the prologue, or at the PC.
3722 This fixes a problem where it walks down into the code for the
3723 user's statements if that code looks like function prologues.
3724 Mark Fox and I have been bouncing this code back and forth, making
3725 small changes to it. Callers changed to match.
3727 Tue Feb 26 01:47:07 1991 Cygnus John Gilmore (cygnus at yuba)
3729 Cleanup for gdb-3.94 release final:
3731 * Makefile.dist: Remove remote-vx.c, remote-nindy.c, and all
3732 the .c files from vx-share and nindy-share, from the various
3733 macros, since they are not found via ALLDEPFILES.
3734 (SFILES): Add tm-i960.h.
3735 (alldeps.mak rule): Break out ALLDEPFILES_MAINDIR and
3736 ALLDEPFILES_SUBDIR. List all the nindy and vxworks subdir files
3738 (TAGFILES_MAINDIR): Change ALLDEPFILES to ALLDEPFILES_MAINDIR.
3739 (gdb.tar.Z): Use ALLDEPFILES_SUBDIR as well as SFILES_SUBDIR.
3741 Mon Feb 25 16:02:35 1991 Cygnus John Gilmore (cygnus at oldman)
3743 * am29k-tdep.c: Add contribution line.
3744 (examine_prologue): Cache information about function prologues in
3745 the misc-function-vector to avoid lots of references over the
3746 serial line while examining instructions.
3748 * core.c (core_close): New function made from cleanup_core.
3750 * core.c, exec.c, inftarg.c, remote-eb.c, remote-nindy.c,
3751 remote-vx.c, remote.c, target.c, target.h,
3752 Update target_ops vector to add attach, close, and load entries.
3753 Use add_syms_addr_command, not add_file_addr_command, for
3754 add_file. Break out close routine from existing code.
3756 * dbxread.c (really_free_pendings): Don't free pending_blocks;
3757 they are in an obstack.
3758 (read_dbx_symtab): Relocate end_of_text_addr in the psymtab.
3760 (define_symbol): Add symbol type parameter; change callers;
3761 pass type parameter to DBX_PARM_SYMBOL_CLASS macro to allow
3762 it to influence the symbol class on the i960.
3763 (define_symbol): Swap LOC_CONST's into target byte order.
3765 * exec.c (exec_close): New function.
3766 (exec_file_command): Call it.
3768 * findvar.c (read_relative_register_raw_bytes): Doc byte order,
3769 Fix byte order of frame pointer.
3770 (read_var_value): Result of 0 if var's value can't be found,
3771 e.g. missing FRAME_ARGS_ADDRESS. Byte-swap LOC_CONST and
3772 LOC_LABEL values to target order. Add LOC_LOCAL_ARG.
3773 (locate_var_value): Use read_var_value and use its lazy address
3774 as the location of the var's value. Lint.
3776 * i960-pinsn.c (next_insn): Add routine from vxgdb for scanning
3779 * i960-tdep.c (arg_address, i960_frame_find_saved_regs): Remove
3780 obsolete Intel versions in favor of vxgdb versions.
3781 (check_host, byteswap, byteswap_val, reorder_val): Eliminate
3782 code dealing with byte order of values, which Intel did in host byte
3783 order rather than gdb-4's target byte order.
3784 (i960_frame_chain_valid): Move to nindy-tdep.c.
3785 (examine_prologue, skip_prologue, frame_find_saved_regs,
3786 frame_args_address, leafproc_return, saved_pc_after_call,
3787 pop_frame): Add vxgdb versions from Mark Fox.
3788 (examine_prologue, frame_struct_result_address): Add code
3789 to deal with the saved value of G13 (struct return address
3791 (frame_args_address): Modify Mark's version to prefer the
3792 saved value over the current value in the topmost frame.
3793 Cache result in the frame info to avoid performance hair in
3795 (print_fault): Add gdb960 code for printing faults.
3796 (_initialize_i960): Actually call check_host.
3798 * ieee-float.c (ieee_extended_to_double, ieee_double_to_extended):
3799 add stub routines. FIXME, these currently just return zero!
3801 * infcmd.c (program_info): Use PRINT_RANDOM_SIGNAL.
3802 (attach_command): Call target_attach, not target_open, now.
3804 * infrun.c (normal_stop): Make global, not static, for vx_attach.
3805 (child_attach): Rename from child_open.
3806 (wait_for_inferior): Use PRINT_RANDOM_SIGNAL. If stop_pc is zero,
3807 don't confuse it with a zero step_resume_break_address.
3809 * inftarg.c (child_detach): Eliminate inferior_pid test.
3810 (child_files_info): Clean up message a bit.
3811 (child_ops): Use child_attach, not child_open, to attach.
3813 * mem-break.c: #ifdef out the whole file if BREAKPOINT is not
3814 set (e.g. on VxWorks or NINDY). Move read_memory_nobpt from
3815 findvar.c to here, since it depends on the contents of the
3816 shadow_contents of breakpoints, but keep if #if 0 since it is
3819 * nindy-tdep.c: New file, contains nindy_frame_chain_valid, moved
3822 * printcmd.c (address_info): Handle LOC_LOCAL_ARG. Lint.
3823 (ptype_command, display_command): Eliminate have_inferior_p and
3824 have_core_file_p in favor of target_has_stack or
3825 target_has_execution.
3826 (print_frame_args): Handle LOC_LOCAL_ARG. Eliminate duplicate
3827 code for actually finding the values of arguments, though we still
3828 keep track of the maximum stack offset for use in printing unnamed
3829 arguments. Handle missing FRAME_ARGS_ADDRESS.
3831 * remote-nindy.c (i960_print_fault): Move to i960-tdep.c.
3832 (struct nindy_regs): Define registers passed to/from nindy.
3833 (nindy_fetch_registers, nindy_store-registers): Translate between
3834 nindy and GDB formats for the registers.
3835 (dcache_init): Statically allocate the cache, since it was being
3836 allocated by a malloc that was never freed anyway.
3837 (nindy_create_inferior): Error, not core dump, if no exec file.
3838 (nindy_before_main_loop): Use target_load, not target_add_file.
3840 * remote-vx.c (net_load): Specify large timeout for load
3841 requests. Allow user to break out with INTERRUPT.
3842 (net_break): Remove useless code, clean up. Change callers.
3843 (parse-args, skip_white_space, find_white_space): Clean up arg
3844 parsing to cope with quoted strings.
3845 (net_wait, net_quit): Never call error, just return status.
3846 (vx_read_register, vx_write_register): Cleanup status checking.
3847 #ifdef the code based on which CPU we are using (960 or 68k),
3848 FIXME, this should be completely general but it isn't yet.
3849 (vx_xfer_memory, vx_resume): Cleanup status checking.
3850 (vx_run_files_info): Improve message.
3851 (vx_load_command): Renamed from vx_add_file_command. Allow load
3853 (net_ptrace): Remove unused routine.
3854 (vx_wait): Adopt code from vxgdb960 to cope with broken
3855 connections to target machine and prompt to disconnect. Remove
3856 debug printouts. Map some EVENT_'s to SIGnals.
3857 (add_symbol_stub, vx_open): Print names of object files we found,
3858 and "ok" if we read their symbols OK. Clarify output in general.
3859 (vx_attach, vx_detach, vx_kill): Add these commands.
3860 (vx_convert_from_virtual, vx_convert_to_virtual): Simplify.
3861 (vx_run_ops): Turn off all_mem, to avoid spurious msg in the
3862 "info files" output, and create_inferior, since we already have
3865 * stack.c (frame_info): Replace Frame_unknown with 0.
3866 (print_frame_arg_vars): Handle LOC_LOCAL_ARG.
3867 (return_command): Pop until the PC matches as well as the FP,
3868 so it works even if the FP is shared with another function,
3869 as in "frameless" or "leaf" procedures.
3871 * symfile.c (load_command): renamed from add_file_target_command.
3872 (add_syms_addr_command): renamed from add_file_addr_command.
3873 (add_syms_command): Stub to call target_add_syms.
3874 (_initialize_symfile): Change command names and descriptions,
3875 add-file => add-syms, and load from alias to its own command.
3877 * target.c (kill_or_be_killed, maybe_kill_then_attach,
3878 maybe_kill_then_create_inferior): Default for attempts to start
3879 a process, if one is already running, is to ask about killing
3880 it and retry if yes.
3881 (upstack_create_inferior): #if-0 it, strata obsolete it.
3882 (push_target, unpush_target, pop_target): to_close() a target
3883 before unstacking it.
3884 (target_info): Renamed from target_files_info.
3885 (_initialize_targets): Rename "i files" as "i target", accessible
3888 * target.h: Improve comments about the target_ vectored routines.
3890 * tm-i960.h: Remove NINDY-specific stuff to tm-nindy960.h.
3891 Convert commenting style to standard GNU style.
3892 (DBX_PARM_SYMBOL_CLASS): allow LOC_LOCAL_ARG's to be recognized.
3893 (SKIP_PROLOGUE): No longer a no-op.
3894 (SAVED_PC_AFTER_CALL): Now handles leaf procedures.
3895 (*_REGNUM): Sort register numbers.
3896 (REGISTER_BYTES, REGISTER_BYTE, REGISTER_RAW_SIZE,
3897 MAX_REGISTER_RAW_SIZE, REGISTER_CONVERTIBLE,
3898 REGISTER_CONVERT_TO_VIRTUAL, REGISTER_CONVERT_TO_RAW): Float regs
3899 are now 10 byte extendeds, not 8 byte doubles.
3900 (FRAME_CHAIN_VALID): Make this config-dependent, since it differs
3901 for nindy versus vxworks targets. FIXME, this should possibly go
3902 in the target vector.
3903 (EXTRA_FRAME_INFO, INIT_EXTRA_FRAME_INFO): Cache both
3904 frame_saved_regs and arg pointer with each frame.
3905 (FRAMELESS_FUNCTION_INVOCATION): New leafproc support.
3906 (FRAME_ARGS_ADDRESS): Use cached result.
3907 (FRAME_ARGS_ADDRESS_CORRECT): New, avoids g14 guessing.
3908 (FRAME_FIND_SAVED_REGS): Change arg to subsidiary fn.
3909 (PRINT_RAMDON_SIGNAL): Call print_fault.
3910 (POP_FRAME): Now works.
3912 * tm-nindy960.h: Break this off tm-i960.h. NINDY-specific
3913 option parsing and startup; STACK_END_ADDR, FRAME_CHAIN_VALID,
3914 BREAKPOINT, and DECR_PC_AFTER_BREAK are here.
3915 (ADDITIONAL_OPTION_HANDLER): use target_load, not
3918 * tm-vxworks960.h: Break this off tm-i960.h. VxGDB specific
3919 startup; DECR_PC_AFTER_BREAK, and FRAME_CHAIN_VALID are here.
3921 * valarith.c (value_subscripted_rvalue): Avoid handling
3922 floats and doubles specially; it gave alignment errors. Lint.
3924 * valops.c (value_of_variable, value_of_this): Error if unknown
3927 * valprint.c (print_floating): Bcopy rather than pointer-deref,
3928 to avoid alignment problems.
3929 (value_print): Handle unknown value address.
3930 (cplus_val_print): Two args are ignored; remove them. Change caller.
3931 (val_print): Use unpack_long rather than pointer-deref.
3934 (unpack_long, unpack_double): Use bcopy rather than pointer-deref
3935 to avoid alignment problems.
3936 (value_being_returned): Error if return value unknown.
3937 (set_return_value): Add bogosity warning, FIXME. *
3939 * TODO: A woman's work is never done.
3941 * Makefile.dist: Distribute REMOTE_OBS into tconfig files.
3942 Separate INCLUDE_CFLAGS for use with lint. Add LINTFILES.
3943 Add ieee-float.o to OBS.
3944 * tconfig/{nindy960,vxworks68,vxworks960}: Include the desired
3945 REMOTE_OBS remote-interface files in the TDEPFILES and TM_FILE.
3946 * tconfig/i960: FIXME. Half-merge, produce warning if config'd.
3948 Changes to generalize the VxWorks RPC protocol slightly, to handle
3949 i960 as well as 68000.
3951 * vx-share/dbgRpcLib.h (VX_SOURCE_STEP): Add.
3952 * vx-share/reg.h: Produce i960 regs #ifdef I80960
3953 * vx-share/xdr_ptrace.c: Skip FPA registers if 960.
3954 * vx-share/xdr_rdb.h: Add SOURCE_STEP struct and xdr decl.
3955 * vx-share/xdr_rdb.c: Add xdr_SOURCE_STEP routine.
3956 * vx-share/xdr_regs.c: Add xdr_regs, xdr_fp_status, xdr_ext_fp
3957 for i960. Change xdr_vectors to xdr_opaques for 68k registers,
3958 so they will move in target byte order rather than network
3959 byte order (happens to be the same).
3961 Mon Feb 25 03:41:44 1991 John Gilmore (gnu at cygint.cygnus.com)
3963 * tm-convex.h (END_OF_TEXT_DEFAULT): Remove #if 0'd block.
3965 Sun Feb 24 00:55:53 1991 John Gilmore (gnu at cygint.cygnus.com)
3968 Add contribution lines to various files, showing where they
3971 * breakpoint.c (break_insn, check_break_insn_size,
3972 read_memory_nobpt): Remove to mem-break.c.
3974 * xm-*.h, param-no-tm.h, tm-29k.h, valprint.c: Change BYTE_ORDER to
3977 * tm-29k.h (STAB_REG_TO_REGNUM): Warn user if symbol table
3978 entry has bad register number. This change is not
3979 tested in this release, FIXME.
3981 * frame.h: Eliminate Frame_unknown in favor of a simple zero.
3984 * value.h: Force value's contents field to be aligned to hold
3985 at least a double or a long long (if supported). This avoids
3986 doing bcopy's in and out of the contents field.
3988 (step_1): Avoid coredump under obscure circumstances when we
3991 * symtab.h (misc_info): Add field to misc function vector for
3992 any kind of cached information the target code desires. AMD
3993 29000 uses this to avoid repeating examine_function_prologue's.
3995 * coffread.c: Lint. Remove static symfile, read_section_header.
3996 core.c (have_core_file_p): Lint: remove.
3997 expprint.c (print_subexp): Lint.
3998 infptrace.c, valops.c, valprint.c: lint.
4000 Roll in changes from vxgdb-5.0.1:
4002 * symtab.h: Comment byte order of each address class. Add
4003 LOC_LOCAL_ARG for frame-relative args (960).
4004 expread.y: Use LOC_LOCAL_ARG where LOC_ARG is used.
4005 symtab.c, symmisc.c: ditto.
4007 * infrun.c (init_wait_for_inferior): Clear stop_signal.
4009 * remote.c (remote_resume): Error if resume with a signal.
4011 * symfile.c (prim_record_misc_function): Clear misc_info.
4012 (fill_in_vptr_fieldno): Check stub type of arg.
4014 * valops.c (value_cast): Avoid looking up names of types whose
4015 name we don't know, to prevent coredump. Sun CC produces typedef
4016 rtx and the name of *rtx is zero...
4018 Mon Feb 18 21:16:25 1991 John Gilmore (gnu at cygint.cygnus.com)
4020 Roll in changes from final AMD 29000 port (Tiemann).
4022 tconfig/am29k: Add COFF_ENCAPSULATE and TARGET=TARGET_AM29K
4023 for ../include/a.out.encap.h. This might not work now that BFD
4024 is separately compiled. Instead, BFD support for encap will have
4025 to translate machine type 29k into the right COFF_MAGIC.
4027 * infcmd.c: Remove references to inferior_pid that aren't used
4028 in actual ptrace calls; use target_has_execution, etc.
4029 (have_inferior_p): Remove function.
4030 (program_info): Print target info rather than "process number";
4031 avoid gratuitous messages unless from_tty.
4032 (run_stack_dummy, finish_command): Set proceed_to_finish.
4033 infrun.c: Remove inferior_pid refs. Decl & init proceed_to_finish.
4034 main.c: Lint. Lose have_inferior_p().
4035 inferior.h (have_inferior_p): Remove, lint.
4036 (proceed_to_finish): Add flag to ask that all regs be saved
4037 by normal_stop, for the few commands that need it, speeding up
4038 serial I/O. Add comments to stop_registers.
4040 * remote-eb.c: Remove newline from breakpoint message we grep
4041 for. Never time out when running the user program.
4045 Wed Feb 13 15:34:40 1991 John Gilmore (gnu at cygint.cygnus.com)
4047 Roll in changes from vxgdb-5.0.1:
4049 * dbxread.c (read_dbx_symtab): If we encounter a "FORTRAN COMMON"
4050 symbol in its raw form, we are processing an unlinked ".o" file.
4051 See if the target environment has assigned it an address, using
4052 target_lookup_symbol (VxWorks does), and enter it into the symtab
4055 * tm-vxworks.h (FRAME_CHAIN, FRAME_CHAIN_VALID): Override usual
4056 68k versions for a simpler version that assumes zero FP at bottom.
4057 Fixes bug of truncated stack reports.
4059 * target.h (target_lookup_symbol): Define this routine's args
4060 and result, finally.
4062 * target.c (nosymbol): Default routine for target_lookup_symbol.
4063 (target_default): Default lookup_symbol and call_function too.
4064 (files_info): Only print has_all_memory warning if a non-dummy
4067 * remote-vx.c (vx_read_register, vx_convert_to_virtual,
4068 vx_convert_from_virtual): If target does not have floating point,
4069 zero register "values", and avoid doing cross-net conversions.
4070 (vx_lookup_symbol): Rename net_lookup_symbol, add to vectors.
4071 (vx_open): Rearrange code that attaches to target and reads
4072 symbols for all loaded modules, to work if some of the modules
4073 are not accessible. Add symbol_stub() and add_symbol_stub()
4074 as callbacks from catch_errors(). Allow connect attempt to be
4075 interrupted painlessly with ^C (FIXME, there are still some bugs
4076 if the interrupt happens during symbol reading.). Print
4077 final message with puts_filtered, since symbol messages are
4082 * main.c (catch_errors): Only print errstring if non-null.
4083 (command_loop): Avoid an ioctl per command to test ISATTY.
4085 * remote-vx.c (net_load): make static; avoid sophomoric msg.
4086 (vx_xfer_memory): Return correct result!
4087 (vx_files_info): Indicate whether target has float or not.
4088 (vx_lookup_symbol): Complain, not error, if target gone.
4089 (vx_open): Print "Connected" msg before disabling immediate-quit.
4090 [FIXME: lookup_symbol and vx_open changes need testing.]
4092 target.c, remote-eb.c, inftarg.c, am29k-opcode.h, target.h,
4093 tm-29k.h, tmm-vxworks68.h, symfile.c, gdb-int.texinfo: Add
4094 contributor lines and update copyrights to 1991.
4096 Changes from an attempted H-PUX host port:
4098 * infptrace.c (PT_ATTACH, PT_DETACH): Handle HP/UX, which
4099 defines PT_ATTACH and PT_DETACH but not PT_KILL.
4100 * remote-eb.c (eb_open): Misplaced endif kills sysv H/PUX.
4101 * remote-vx.c: include <sys/time.h> for HPUX.
4102 * hp300hpux-xdep.c (fetch_core_registers): Rewrite old
4103 "core_file_command" routine to BFD regime. May not work yet.
4105 Attempted port of "gdb-3.4 Van Jacobson xgdb" to modern gdb.
4107 * xgdb.c: Replace X10 version with some VJ version.
4108 (FIXME: Its copyright assignment is not on record.)
4109 * xgdb.c: Update include files to X11R4 (Xaw crud).
4110 (xgdb_display_source, create_text_widget): fix call to
4111 get_filename_and_charpos. Rewack source window stuff for X11R4
4112 (gleaned from include files, and "nm's" of binary libraries, since
4113 I had no doc available).
4114 (append_selection, append_selection_word): Disable with FIXME
4115 since R4 changed interface here.
4116 (create_buttons): Add back the old set of buttons.
4117 (xgdb_create_window): Fix call to XtInitialize (&argc not argc).
4119 * Makefile.dist (xgdb, xgdb-init.c): Update for X11R4 on Suns.
4120 Roll VERSION to 3.94 (not yet final though).
4122 Sat Feb 9 09:46:25 1991 John Gilmore (gnu at cygint.cygnus.com)
4124 * obstack.h (obstack_ptr_grow, obstack_ptr_grow_fast,
4125 obstack_int_grow, obstack_int_grow_fast): Eliminate
4126 cast on left of assignment, which gives MIPS cc fits and is
4129 * sparc-pinsn.c (print_insn): Eliminate 'set' test, subsumed by
4130 F_ALIAS. Use printf, not fprintf, when not passing a file
4132 (compare_opcodes): Check that identical instructions have
4133 identical opcodes, complain otherwise.
4135 * sparc-opcode.h (st %fsr): Fix opcode "lose" mask. This
4136 was reported by Roland McGrath.
4137 (unimp): Only match if exactly zero instruction. (Roland)
4138 (branches and traps): Generate all variations of these
4139 instructions with macros, based on a single call that defines
4140 each condition name and its binary representation.
4141 (set): Turn on alias bit, to avoid test in sparc-pinsn.c.
4143 * valprint.c (val_print_fields): Take, and use, format parameter.
4144 This means that "p/x struct" again prints the elements in the
4145 desired format. Changed callers.
4147 * stack.c (frame_info): Use filtered output, and indicate wrap
4148 points. Remove kludgy formatting designed to avoid line wrap.
4150 * utils.c (wrap_here): If the line is already full (because
4151 we had printed a long indent or long wrapped string), do an
4152 immediate newline-and-indent.
4154 * m68k-pinsn.c (print_insn_arg): Bugfix from
4155 ntmtv!thompson@ames.arc.nasa.gov (Mike Thompson): 'bkpt #0'
4156 instruction is incorrectly disassembled as bkpt #8.
4158 * dbxread.c (end_psymtab): Bugfix from Peter Schauer
4159 <pesrem@regent.e-technik.tu-muenchen.de>: If you want to set a
4160 breakpoint in a *.y file gdb will say Reading in symbols for *.y...
4161 and then will dump core (sometimes). I traced it back to an
4162 uninitialized symfile_name in psymtab_to_symtab.
4163 (const_vol_complaint): Add quotes to message.
4164 (define_symbol): Only believe line number if gcc_compiled.
4165 Avoid allocating symbol if we will not return it.
4167 Add target strata support so that newly established targets go
4168 into their right place in the target stack (e.g. a new exec file
4169 doesn't wipe out the ability to access the running process).
4171 * target.h, core.c, exec.c, inftarg.c, remote-eb.c,
4172 remote-nindy.c, remote-vx.c, remote.c, target.c: Add to_stratum
4173 and initialize it properly in all the targets.
4175 * target.h: Document strata. Change return type of push_target.
4177 * target.c (nomemory): new function for dummy memory access.
4178 (tcomplain): Rename complain, now also used in symfile.c.
4179 (push_target): Push targets within strata. New return value shows
4180 whether new target is on top of stack or not. Always keep dummy
4182 (target_files_info): Ignore dummy target.
4184 * core.c (core_open): Warn user, and skip accessing file, if the
4185 core target is not the topmost target in the stack.
4186 * remote-nindy.c (nindy_create_inferior): Avoid unpush_target, now
4189 * remote-vx.c: Remove vx_prepare_to_store from vxworks memory
4190 target_ops, it doesn't belong there since we have no regs there.
4191 Change name of target from machine => memory to clarify.
4193 Thu Feb 7 16:32:09 1991 John Gilmore (gnu at spiff.cygnus.com)
4195 * Freeze version 3.93 for release.
4197 * Makefile.dist: Handle vx-share and nindy-share subdirs
4198 properly when building gdb.tar.Z.
4200 * symtab.c: lint; add no_symtab_msg to consolidate the messages
4201 printed in various places, so I could change just one copy.
4203 * dbxread.c, coffread.c: Change references to bfd->iostream
4204 to cast to FILE *, now that BFD avoids needing types defined
4205 in other header files.
4207 Tue Feb 5 21:39:35 1991 John Gilmore (gnu at cygint.cygnus.com)
4209 * command.c, dbxread.c, expprint.c, infcmd.c, infptrace.c,
4210 infrun.c, printcmd.c, remote-nindy.c, source.c, sparc-tdep.c,
4211 sparc-xdep.c, symfile.h, symmisc.c, utils.c, valprint.c: Lint
4212 (actually gcc -Wall).
4214 * dbxread.c: Remove first_global_sym, last_global_sym, since
4215 they are never referenced.
4217 * defs.h (baud_rate): Declare.
4218 main.c: Define it, and add the -b option to set it.
4220 * gdb-int.texinfo: Add text on how to define a new host or target
4221 architecture, prompted by Per Bothner's questions about MIPS
4224 * gdb.texinfo: Document "complaints". Change doc of -q since
4225 gdb no longer prints the copyright and blurb if you specify a file
4226 name to be debugged (just like Emacs). Add doc for Nindy-specific
4227 command line flags for specifying target serial port and such.
4228 Update copyright to 1991.
4230 * gdbcore.h: Remove a large mass of now-useless crud, since BFD
4231 has taken over for us the job of ripping up executable files. The
4232 crud caused Per Bothner's port to not compile.
4234 * infrun.c (normal_stop): Avoid printing "Program exited
4235 normally" if we are in batch mode. This allows a GDB which
4236 executes a program on a target system, to behave like a Unix
4237 command (input from stdin, output to stdout, no extraneous
4240 * main.c (main): Allow additional machine-dependent command line
4241 options to be specified with the ADDITIONAL_OPTIONS,
4242 ADDITIONAL_OPTION_CASES, ADDITIONAL_OPTION_HELP, and
4243 ADDITIONAL_OPTION_HANDLER macros. Also allow machine-dependent
4244 processing to occur just before the main loop with
4245 BEFORE_MAIN_LOOP_HOOK.
4246 (main): If a "core file" argument is specified, and it is not a
4247 core file, try it as a process ID to attach.
4248 (symbol_completion_function): Attempt to cope with
4249 "show screen-" TAB, not very successfully. This needs more work,
4251 (batch_file): New function, returns whether we are reading
4252 commands from an interactive tty on stdin, or from somewhere else.
4253 Called by normal_stop since it doesn't get from_tty passed down
4254 to it like many commands do.
4256 * remote-nindy.c: Handle command line options for nindy
4258 (nindy_before_main_loop): Prompt user for tty name if they
4259 don't specify it before getting to the interactive command loop.
4261 * tm-i960.c: Add ADDITIONAL_OPTIONS, etc, to handle -O, -brk,
4262 and -r command line options. Also add hook before main loop
4263 to make it easy to specify a tty.
4265 * TODO: More things to do, one done.
4267 Mon Feb 4 23:57:39 1991 John Gilmore and Mike Tiemann (at cygint.cygnus.com)
4269 * dbxread.c: Make complaint() calls pass pointer, not struct.
4270 Add complaints about badly formatted C++ type information
4271 (const/volatile indicator, and parse errors resulting in
4272 error_type). Fix C++ virtual member fn comment.
4273 (read_struct_type): Avoid bumping pointer if we got a parse
4274 error; this prevents our walking beyond the end of a string.
4275 Terminate loop on null char as well as semicolon.
4276 (process_one_symbol): Fix the LBRAC fix so that it uses the
4277 last previous SLINE, FUN, or SO record's PC address. C++ debug
4278 symbols did not have SLINE records in a useful order compared
4279 to the LBRAC records.
4280 (define_symbol): Handle "catch" records.
4282 * symtab.c (check_stub_type): Added new complain
4283 `stub_noname_complain' and added a consistency check to
4284 keep the debugger from crashing when finishing from an
4285 exception frame. A real fix will be needed later.
4287 Sat Feb 2 10:43:05 1991 John Gilmore (gnu at cygint.cygnus.com)
4289 * infcmd.c (attach_command): Make global.
4291 * Makefile.dist (REMOTE_OBS): Make these compile by default,
4292 but make them easy to comment out. Perhaps later they should
4293 be enabled by what CPU you configure for? FIXME.
4294 (VERSION): Roll to 3.93.
4295 (pinsn.o): Remove rule for obsolete file.
4296 (dbxread.o,coffread.o,mipsread.o): Use ${srcdir} explicitly.
4298 Run down a problem that manifested by printing the wrong function
4299 name in stack traces of read_ofile_symtab. Turned out that the
4300 problem was the SunOS 4.1.1 (and previous) C compiler outputs
4301 the LBRAC symbol with an address in the *data* segment, which
4302 blew our binary search through the blocks.
4304 * dbxread.c: Use the complain() facility consistently to bitch
4305 about problems in the symbol file we are reading.
4306 (finish_block): Add code to check the nesting of the blocks;
4307 complain and Procrust them to fit if wrong.
4308 (make_blockvector): Check the order of the blocks, complain
4309 [but don't cope] if wrong.
4310 (process_one_symbol): ifndef SUN_FIXED_LBRAC_BUG, check LBRAC
4311 symbols to be sure their PC value is greater than the last SLINE
4312 (line number) symbol we've seen, complaining and adopting the
4313 SLINE PC value if wrong.
4315 * symfile.h (struct complaint, complaint_root, complain,
4316 clear_complaints): Add.
4317 * symfile.c (complain, complaint_root, clear_complaints): Add
4318 facility to deal with non-fatal complaints and to regularize their
4320 (symbol_file_add): Clear complaint counters to allow new complaints.
4321 (initialize_symfile): Add 'set complaints' and 'show complaints'.
4323 * dbxread.c (dbx_symfile_read): Remember the address and size
4324 of the string table for the main symbol file, so we won't read it
4326 (dbx_psymtab_to_symtab): Fix the check for main symbol file,
4327 to avoid reading the string table yet again. Lint.
4328 (throughout): Improve filtered output, including word wrap.
4329 (read_range_type): Improve Bothner's fix to handle other types too.
4331 * utils.c: Improve line wrap implementation. Handle unlimited
4332 width by making chars_per_line unsigned.
4333 (puts_filtered): New, easy, function.
4335 * defs.h (puts_filtered): add.
4337 * mipsread.c (compare_symbols, sort_symtab): Remove these fns,
4338 call the identical sort_symtab_syms() in symfile.c instead.
4340 * expread.y: Suggest the `file' command rather than `symbol-file'.
4342 * command.h (enum var_types): Add zinteger for seroable
4344 * command.c (do_setshow_command): Handle var_zinteger. Restructure
4345 nested if's into a switch.
4347 * breakpoint.c (bpstat_print): If bpstat "print" flag is not set,
4348 we did not stop because of a breakpoint (it must have been for
4349 some other reason, like a "stepi"), so don't print anything.
4351 * symtab.c: Include <sys/types.h> all the time. Now that BFD
4352 doesn't include <sys/types.h>, old SunOS's require it for
4355 Sat Feb 2 10:39:15 1991 Per Bothner (bothner@cs.wisc.edu)
4357 A test port of gdb-3.92.6 to the Sony NEWS.
4360 Don't normally link in remote- or vx stuff.
4361 Some of it doesn't compile, and it wastes space for 99% of the users.
4362 Remove reference to no-longer-used HAVE_VPRINTF.
4363 Fixed BFD_DEP typo to BFD_DIR.
4365 Fix cast in arg to bfd_h_getlong.
4366 Make char *prefix be const.
4367 Fix how certain range types are mapped into builtin unsigned int types.
4369 Remove 2 #includes. They cause errors (on Sony, at least),
4370 and aren't needed (they wern't in earlier versions).
4372 print_address_symbolic should never demangle labels
4373 (since it prints *assembler-level* labels).
4375 [This was superseded by the change to printcmd below.]
4378 Add some "volatile" return types to avoid warnings.
4379 If MISSING_VPRINTF add vprintf function and not just macro
4380 (since vprintf is used in printcmd.c).
4382 Unless __GNUC__, use obstack_grow instead of obstack_ptr_grow.
4383 (The latter isn't grokked by some PCC-based compilers.)
4385 [This change is in abeyance, we prefer to fix obstack_ptr_grow.]
4387 Make chunk size of dont_print_obstack 32*4 instead of default 4096.
4388 * nindy-share/coffstrip.c
4389 Added some forward declarations (otherwise, gcc complains
4390 about implicit extern redefined as static).
4392 Sun Jan 20 02:38:19 1991 John Gilmore (gnu at cygint.cygnus.com)
4394 Changes inspired by Per Bothner:
4395 * printcmd.c (print_address_symbolic): Take additional parameter
4396 specifying whether to demangle.
4397 (print_address): Pass in asm_demangle to control demangling.
4398 (print_address_demangle): New fn, takes explicit arg to control
4400 * utils.c: Add new vars demangle and asm_demangle, and let them
4402 (fputs_demangled): If !demangle, just print the argument.
4403 (fprint_symbol): If !demangle, just print raw symbol.
4404 * valprint.c (val_print): Call print_address_demangle rather than
4405 print_address, to cause demangling to depend on the global
4406 rather than assembler-level demangling setting.
4407 * WHATS.NEW, gdb.texinfo: Document.
4409 * main.c (show_command): Show all settings if no arg.
4410 (initialize_main): Make "info set" the same as naked "show".
4411 * command.c (cmd_show_list): Handle prefix commands in the
4412 list, and print the name of the setting as well as its English
4413 description and value.
4415 Allow gdb functions to specify where a line should wrap if it
4416 exceeds the size of a terminal line. Use it to make the output
4418 * utils.c (set_screen_width_command): New fn, mallocs a buffer
4419 of the right size when screen width changes.
4420 (set_screensize_command, screensize_info): Remove #if 0'd fns.
4421 (wrap_here): New fn, indicates a point in the output where we
4422 should wrap the line rather than just letting it overflow at a
4424 (fputs_filtered): Implement wrapping.
4425 (n_spaces): New fn, returns a pointer to N spaces.
4426 (print_spaces_filtered): Use n_spaces.
4427 * defs.h (n_spaces): Declare.
4428 * stack.c (print_frame_info): Wrap with 4-space indent after
4429 fn name and before filename and line number.
4430 * printcmd.c (print_frame_args): Wrap with 4-space indent
4431 before each argument name is printed.
4432 * valprint.c (value_print): Wrap with no indentation before
4434 (val_print_fields): Wrap with indentation relative to nesting
4435 level before each field name.
4436 (val_print): Wrap with nesting indentation before array elements.
4437 * command.c (do_setshow_command): Avoid extra newlines,
4438 wrap with 4-space indent around values printed, end with period.
4439 * WHATS.NEW, gdb.texinfo, gdb-int.texinfo: Document.
4441 * breakpoint.c (breakpoint_1): Implement addressprint for
4442 "info breakpoints" display. Change file name and line number
4443 format to " at file:nnn" rather than " (file line nnn)".
4444 * gdb.texinfo: Document.
4447 Fri Jan 18 07:21:25 1991 John Gilmore (gnu at cygint.cygnus.com)
4449 Frozen for gdb-3.92.6 release.
4451 README, WHATS.NEW: Update for 3.92.6 release.
4453 tconfig/{altos, i386v, i386v32, m88k, umax}: Eliminate
4454 coffread.o from configs since it is now built by default.
4455 tconfig/{3b1, altosgas, arm, convex, hp300bsd, hp300hpux,
4456 i386v-g, i386v32-g, isi, merlin, news, news1000, np1, pn,
4457 pyramid, symmetry, vax, vxworks68}: Eliminate dbxread.o
4458 from configs since it is now built by default.
4460 Makefile.dist: Update for release 3.92.6. Handle files that
4461 have been moved to ../include, ../getopt, or ../bfd. Add
4462 saber.suppress and tests directory. Add config.status to
4463 the release (it will say "none").
4465 coredep.c: Minor formatting fixes.
4467 These changes were made in early December but only checked in now:
4468 * nindy-share/Onindy.c, nindy-share/coffstrip.c,
4469 nindy-share/nindy.c: lint
4470 * nindy-share/nindy.c (ninStopWhy): Don't byteswap the
4471 register values coming back from the target; we store values
4472 in target byte order everywhere.
4474 Wed Jan 16 19:01:37 1991 John Gilmore (gnu at cygint.cygnus.com)
4476 * am29k-opcode.h, am29k-pinsn.c: Add 29050 opcodes.
4478 * valprint.c (cplus_val_print, val_print_fields): New functions,
4479 which print C++ objects. They conspire to avoid printing a
4480 virtual base class more than once, following all the twists and
4481 turns of C++ virtual base rules.
4482 (val_print): Call the above rather than do it by hand.
4484 * symfile.c (symbol_file_add): Only reset symfile_mtime for main
4485 symbol file, not for added files like shared libs. This really
4486 needs to be generalized to a timestamp per file.
4488 * core.c (cleanup_core): Avoid coredump if no core file.
4490 * config.gdb: Accept -host or -target in place of +host or
4493 * coffread.c (find_linenos): Avoid desupported BFD interface
4494 to line numbers. We still read them manually rather than using
4495 BFD's "generic" features.
4497 * gdbrc.tex, threecol.tex: Add GDB reference card and its
4499 Makefile.dist: Add refcard to OTHERS list for creating tar files.
4501 * Makefile.dist: Eliminate use of $< in explicit targets.
4503 * readline/Makefile: Use $< rather than $*.c, which does not
4504 include the VPATH in GNU Make.
4506 * tconfig/i960-bout, tconfig/i960-coff: These are identical
4507 copies of tconfig/i960, added for global configuration
4508 compatability. All i960 versions can read both coff and b.out.
4510 * tm-88k.h: Fix multiline macro that lacked \'s. Remove
4511 COFF_FORMAT and COFF_CHECK_X_ZEROES since these are now handled
4514 * TODO: Think of more things to do.
4516 Wed Jan 2 19:09:29 1991 John Gilmore (gnu at spiff.cygnus.com)
4518 tconfig/{am29k,i960,sun2*,sun3*,sun4*}: Eliminate config
4519 of sdb versus dbx debug symbols. Add kludge for 68881 80-bit to
4520 64-bit float conversion.
4522 tconfig/sun4, tconfig/sun3, xconfig/sun4, xconfig/sun3: Make
4523 equivalent to sun?os4 so global config works.
4525 Wed Jan 2 18:20:51 1991 John Gilmore (gnu at spiff.cygnus.com)
4527 Fix from Eberhard Mattes <mattes@azu.informatik.uni-stuttgart.de>
4529 * main.c: Only declare linesize once; declare pagesize not at
4530 all, since it is never used.
4531 (main): Clear newly allocated line before it is used.
4533 Fri Dec 28 00:13:42 1990 John Gilmore (gnu at cygint)
4535 Further stabilization for the Intel 960.
4537 * Makefile.dist: Parameterize the location of the "include"
4538 and "bfd" directories, as well as "getopt". Add symfile.c.
4539 Link in both dbxread and coffread. Fix up "make depend" to
4540 rewack the locations of include, bfd, and getopt in its output.
4542 * README: Document moving include files, improve some of
4545 * coffread.c: Move common code out to symfile.c. Change
4546 symbol_file_command style interface to use new *_symfile_init
4547 and *_symfile_read interface under BFD. Use BFD internal
4548 info to locate line table, symbols, etc.
4550 * core.c (core_fetch_registers): Rename to get_core_registers
4551 to avoid confusion with fetch_core_registers.
4552 (register_addr): Move to coredep.c, which is already machine
4553 dependent. This leaves core.c pretty clean of dependencies.
4555 * coredep.c (register_addr): Accept this routine from core.c.
4557 * dbxread.c: Move common code (with coffread.c, etc) into new
4558 symfile.c. Each psymtab now contains a pointer to the
4559 format-dependent function that knows how to read it in. Make
4561 (dbx_psymtab_to_symtab): Renamed from psymtab_to_symtab_2.
4562 (process_one_symbol): Add code to complain about a "compiler bug
4563 we muzzle here", if we actually see it.
4565 * eval.c (evaluate_subexp): Insert missing "break" statements
4566 in code that determines whether a variable is an lvalue in
4567 memory, register, or whatever. I detected this via a compiler
4568 bug in which it *almost* mashed out the whole switch statement.
4570 * gdb-int.texinfo: Add minor sections on configuring gdb for
4571 release, and about the README file.
4573 * infcmd.c (registers_info): Fix formatting somewhat. Still
4574 not as pretty as before, but it handles byte swapping.
4576 * remote-nindy.c: If data cache routines are interrupted while
4577 waiting for the remote end, be sure that any uninitialized cache
4578 blocks are on the free list, not on the valid list!
4580 * symfile.h: Flesh out this header file with all the various
4581 routines and variables that have been merged in from dbxread.c
4582 coffread.c, and symtab.c to symfile.c.
4584 * symfile.c: New file, containing code common to dbxread.c,
4585 coffread.c, and some code from symtab.c. All generic code for
4586 reading symbol files should be in here now.
4587 (unrecord_misc_function): Remove unused function.
4589 * symtab.h: Remove file-reading things to symfile.h.
4591 * symtab.c: Remove file-reading things to symfile.c.
4593 * tm-i960.h: Fix FRAME_CHAIN types; define PRINT_RANDOM_SIGNAL
4594 to decode i960 fault types.
4596 * target.h, remote.c, remote-eb.c, remote-vx.c, remote-nindy.c,
4597 target.c: Change type of the "resume" function from int to void,
4598 since its result was never used.
4600 Sat Dec 22 02:51:40 1990 John Gilmore (gnu at cygint)
4602 * main.c: Replace "stupid" with "caution"; you now "set caution
4605 * printcmd.c (print_scalar_formatted): Fix typo in 'g' format
4607 * infcmd.c (do_registers_info): Call val_print to deal with the
4608 byte order of the registers being printed. FIXME, this makes
4609 the formatting of the output uglier.
4611 * infcmd.c (wait_for_inferior): If PRINT_RANDOM_SIGNAL is
4612 defined, call it for signals the debugger doesn't itself use.
4613 The i960 uses this for more detailed fault information.
4615 * remote.c (remote_open): If arg is null, print help rather than
4618 * sparc-xdep.c (register_valid): Avoid declaring size, since
4619 various modules will think of various sizes depending on the
4620 architecture of their tm-file. FIXME, we need protection against
4621 actually entering one of those modules, which would clobber
4622 storage if not for the target architecture compiled into gdb.
4624 * stack.c (up_command, down_command): Always print the frame
4626 (up_silently_command, down_silently_command): New commands
4629 * i960-pinsn.c (reg), i960-tdep.c: Lint.
4631 * i960-tdep.c (i960_frame_chain_valid): Lookup_symbol now takes
4632 more parameters than it used to.
4634 * findvar.c (registers): Increase slop to 256 bytes, which should
4635 protect us against even most RISC machines with large register
4637 (locate_var_value): Move declaration inside related ifdef.
4639 * remote-nindy.c (): Use TIOCSETN rather than TIOCSETP
4640 throughout, to avoid throwing away buffered input from the board.
4641 (nindy_wait): Supply_register takes addr_of_value, not value.
4642 (i960_print_fault): Renamed from i80960_fault.
4643 (nindy_fetch_registers): Avoid have_regs stuff, just get them.
4644 (nindy_store_registers): Avoid regs_changed stuff, just stuff
4646 (nindy_create_inferior): Don't bother to write PC_REGNUM since
4647 we can set the PC in the call to proceed(). Unpush nindy_ops
4648 before pushing it on top, to avoid message to user. Eliminate
4649 commentary from Unix machines that just misleads here.
4650 (reset_command): Fix error message to suggest target command.
4652 Wed Dec 19 11:03:56 1990 John Gilmore (gnu at cygint)
4654 Release 3.92.5 as frozen.
4656 Stabilize the merged release...with help from lint, Saber C,
4659 Everywhere: Add include files needed to declare return types
4660 of functions called.
4662 * gdb.texinfo: Roland Pesch is documenting gdb, glory be!
4664 * breakpoint.h: Add undeclared breakpoint functions, and some
4665 functions for display handling since I couldn't think of a better
4668 * breakpoint.c (insert_breakpoints): Make code for disabling
4669 shared library bkpts more likely to work. It's used when we
4670 rerun a program and stop before the shared library has been
4672 (breakpoint_cond_eval, bpstat_stop_status): Pass arg as int,
4673 cast from pointer, so it squeezes through catch_errors.
4674 (bpstat_stop_status): Fix logic broken some time ago. We now
4675 always create a bpstat if the stop address matches a breakpoint,
4676 even if we don't stop there -- just like the old code used to do
4677 before I got my fingers into it (sigh).
4678 (breakpoint_1): Print "ignore count" after "stop only if"
4679 condition, since that's how it actually works.
4680 (mention): Handle watchpoints as well as breakpoints.
4681 (watch_command): use set_raw_breakpoint and mention to do most
4682 of the work (and initialize all the fields!). Only pass one
4683 arg to parse_c_expression, since that's all it takes.
4685 * command.c (not_just_help_class_command): Rename arg to args
4686 since we ignore "unused argument" warnings on vars named "args".
4687 inflow.c (child_terminal_info): ditto.
4688 infptrace.c (kill_inferior): ditto
4689 main.c (catch_errors, version_info, quit_command, pwd_command,
4690 source_command, dump_me_command, editing_info,
4691 set_history_size_command, set_history, show_history,
4693 stack.c (locals_info): ditto
4694 target.c (target_files_info): ditto
4695 valprint.c (set_input_radix, set_output_radix): ditto
4697 * core.c: Remove old variables for handling core and exec file
4698 sections (data_start, data_end, stack_start, stack_end,
4699 reg_stack_start, reg_stack_end, reg_stack_offset, text_start,
4700 text_end, exec_data_start, exec_data_end, text_offset,
4701 exec_data_offset, data_offset, stack_offset). They're
4702 superseded the more general build_section_table and
4704 (get_exec_file): Mention the `file' command.
4705 (read_memory_check): Rename to memory_error, and only call it
4706 in the case of an actual error.
4707 (read_memory, write_memory): call memory_error.
4708 (core_fetch_registers): Register section name is ".reg".
4710 coredep.c: Remove a bunch of crud now that all this file does
4711 is pull the registers out of a core file.
4712 (fetch_core_registers): Rewrite to actually work, I hope.
4714 dbxread.c: Use a.out.gnu.h, not system a.out, now.
4715 Replace index() with strchr(). Remove all the pre-BFD macro
4716 definitions for accessing the symbol file.
4717 (struct dbx_symfile_info): Encapsulate the information that
4718 dbx_symfile_init needs to pass to dbx_symfile_read in this
4721 (dbx_new_init, dbx_symfile_init, dbx_symfile_read,
4722 dbx_symfile_discard): Rearrange symbol file reading to divide
4723 the format-specific part from the format-independent part,
4724 leaving the format-independent part such as file name expansion
4725 and opening in symtab.c. This replaces
4726 partial_symbol_file_open and partial_symbol_file_read.
4727 Symbol_file_read, add_file, add_file_target_command,
4728 add_file_addr_command move to symtab.c. Pass an explicit
4729 "mainline" flag for when reading the main symbol table, rather
4730 than relying on the offset address to be zero or nonzero.
4732 (dbx_symfile_read): Don't allow void *'s to be printed as
4734 (SWAP_SYMBOL): Use bfd routines to byte-swap the symbols.
4735 (ADD_PSYMBOL_TO_LIST): Make the "function call rather than
4736 macro" debug version really work.
4737 (read_dbx_symtab): Remove unref'd parameter inclink.
4738 Avoid swapping N_SLINE symbols, for speed.
4739 Merge N_TEXT!N_EXT case with the other external symbol
4740 definitions' case. Add comments.
4741 (start_psymtab): Allocate the symfile name in the psymtab on
4742 the psymbol_obstack, rather than using the caller's storage.
4743 (end_psymtab): Only allocate a dependencies list if there are
4745 (psymtab_to_symtab_2): Use BFD when reopening file to read
4746 its symbols for real.
4747 (read_struct_type): Add FIXME comments where it needs work
4749 (read_huge_number): Add FIXME about overflows.
4750 (read_range_type): Add FIXME about comparing a long to 1<<32.
4752 * coffread.c: Minor changes to move things closer to the new
4753 regime with symtab.c and dbxread.c Major work is still needed
4756 * exec.c (exec_file_command): Remove old variables (see core.c
4758 (xfer_memory): If memory transfer is right at the end of a
4759 section, don't lose.
4761 * findvar.c (get_saved_register): If value is in a real
4762 register, LVAL is lval_register, not lval_memory.
4764 frame.h: Declare print_sel_frame and record_selected_frame.
4766 gdb-int.texinfo: New file, for GDB internals documentation.
4767 Very simple, unformatted doc of cleanups is there for now.
4769 gdbcore.h: Remove obsolete variables that described a.out
4770 section addresses and offsets. (See core.c above.)
4771 Declare fetch_core_registers and registers_fetched.
4773 getopt.c: Declare char *alloca(); even on SPARC.
4775 infcmd.c (run_command): Call target_kill rather than
4777 (step_command, next_command, stepi_command, nexti_command):
4778 Declare from_tty parameter even though we don't use it.
4779 (run_stack_dummy): argument BUFFER is a char array, not
4780 a pointer to REGISTER_TYPE.
4781 (finish_command): using_struct_return needed a value *,
4782 not a struct symbol *.
4784 * infptrace.c (child_xfer_memory): To avoid dependency on
4785 where sections are in memory, try PT_WRITE_D and if that fails,
4786 try PT_WRITE_I. Most Unixes don't care which you use.
4788 * infrun.c (step_resume_break_shadow): Change to array to
4789 match other breakpoint shadow storage.
4790 (clear_proceed_status): Pass address of bpstat to
4791 bpstat_clear, not the bpstat itself.
4792 (child_create_inferior): FIXME comment about if the child
4794 (start_inferior): Remove old function.
4795 (child_open): Use target_kill rather than kill_inferior.
4796 (wait_for_inferior): Ditto.
4797 (insert_step_breakpoint, remote_step_breakpoint): Use
4798 new step_resume_break_shadow.
4800 * inftarg.c (child_wait): If all child processes die,
4801 pretend that the one being waited for exited with signal 42.
4803 * main.c (command_line_input): When scanning for comments,
4804 don't coredump on unclosed quotes.
4805 (quit_command): Use target_kill rther than kill_inferior.
4806 (_initialize_main): Rename class_user from "user" to
4809 * printcmd.c (print_command_1): Initialize "fmt" if no format
4810 is specified by the user.
4811 (print_frame_args): Only add to args_printed if we are
4812 actually fetching args from the stack (avoiding undefined
4814 (_initialize_printcmd): Remove bogus \{ from string.
4816 * remote-eb.c (eb_open): Avoid coredump on no argument.
4818 * remote-nindy.c: Bring out of Intel environment into new
4819 target environment. Remove all conditional compilation on
4820 I80960. Massive hacking throughout.
4821 (nindy_xfer_inferior_memory): New routine stolen from
4823 (nindy_create_inferior): New routine pieced together, probably
4824 not quite working yet.
4825 (nindy_ops): New target_ops struct for nindy.
4827 * remote-vx.c: Use write_memory rather than target_write_memory
4828 to get error checking.
4829 (vx_add_file_command, vx_open): Use symbol_file_add rather than
4831 (vx_create_inferior): Use target_terminal_ours...
4833 * signame.c (_initialize_signame): Always initialize, since
4834 we need the table for things other than psignal.
4836 * solib.c (solib_add): Use symbol_file_add, not add_file.
4837 (solib_address): Return boolean result rather than struct
4838 pointer which nobody else knows the type of.
4840 * sparc-tdep.c, valops.c: Use write_memory rather than
4841 target_write_memory, to get error checking.
4843 * stack.c (locals_info, catch_info, args_info,
4844 get_selected_block, frame_command, up_command): Use
4845 target_has_stack, rather than have_inferior_p or
4848 * sun3-xdep.c (fetch_core_registers): Rewrite for new BFD regime.
4850 * symfile.h: New file, defining the interface between the
4851 generic and object-file-specific symbol reading code.
4853 * symtab.c: Move generic symbol-reading interface to symtab.c,
4854 from dbxread.c, coffread.c, mipsread.c, etc. Add symtab_fns
4855 table to map BFD targets to symbol-reading modules in GDB.
4856 Change index to strchr.
4857 (lookup_struct_elt_type): Use error() rather than hand-made
4858 simulations thereof.
4859 (lookup_partial_symbol): Speedup slightly when length == 0.
4860 (symbol_file_add): New function.
4861 (symbol_file_command): Call it.
4862 (symfile_open, symfile_init): New function.
4863 (add_file_target_command, add_file_addr_command): moved from
4866 * target.c (target_command): use target_kill.
4868 * target.h (target_files_info): Don't declare, never called
4871 * tm-sun2.h, tm-sun3.h (STACK_END_ADDR): Use system include
4872 files to determine stack end address.
4874 * valarith.c (value_x_binop, value_x_unop): Change error message
4875 to be more useful. Pass proper argument to value_struct_elt.
4877 * valops.c (value_assign): FIXME comment that long long
4878 bitfields will break here.
4880 * Makefile.dist: Add symfile.h, remote-nindy.c, remote-eb.c.
4881 Update `make saber_gdb' to work better.
4883 * TODO: A woman's work is never done.
4885 * cplus-dem.c, environ.c, inferior.h, infrun.c, inftarg.c,
4886 main.c, obstack.c, printcmd.c, remote-eb.c, remote-nindy.c,
4887 remote-vx.c, remote.c, solib.c, source.c, sparc-pinsn.c,
4888 sparc-tdep.c, sparc-xdep.c, symmisc.c, symtab.c, symtab.h
4889 target.c, terminal.h, tm-sparc.h, tm-sunos.h, utils.c,
4890 valops.c, valprint.c, exec.c: Lint.
4893 Wed Dec 12 23:44:15 1990 John Gilmore (gnu at cygnus.com)
4895 Continuing Intel 960 port merge of GDB.
4897 * Makefile.dist: Merge i960 "nindy-share" files. Rename
4898 malloc.h to gmalloc.h to avoid name conflicts in /usr/include.
4899 Don't ship gdb.dvi in tar file. Link gdb with init.o, not init.c.
4900 Wack over "make depend" so it handles files in subdirectories
4901 vx-share, nindy-share, bfd, and in the current directory.
4903 * blockframe.c (get_prev_frame_info): Remove fatal error
4904 if stack not defined.
4906 * core.c (core_open, core_detach): New functions that handle
4907 the old "core-file" command as "target core" and "detach" instead.
4908 (core_file_command): Call them.
4909 (core_xfer_memory): Use common routine xfer_memory.
4911 * dbxread.c: Include a.out.gnu.h, not system a.out.h.
4912 dbxread now uses bfd for everything but symbol reading itself.
4913 BFD internals are used to drag out the relevant file offsets.
4914 (partial_symbol_file_open): Change args all around for BFD.
4916 * symtab.c: Rename "value" to "val" everywhere, so we can
4918 (symbol_file_command): New command, moved from dbxread.c
4919 and coffread.c. It uses BFD to read the file, then vectors
4920 based on its type, to dbx or coff symbol readers.
4921 * symtab.h: Extern a few vars for symbol_file_command.
4923 * target.h: Breakpoint takes a char * save area, not a char **.
4925 * valprint.c (val_print): When unpacking bitfields, offset
4926 the address in gdb of the value, if it is declared with a shorter
4927 type. Remove the last "runtime kludge test" of host byte order.
4929 * utils.c: Remove old my_bfd_read routine.
4931 * stack.c (frame_info): Use target_has_stack. Print program counter
4932 register's actual name rather than "pc", since it's called the
4933 "ip" (instruction pointer) on the i960 (sigh).
4935 * target.c (target_command): Add command for selecting a target
4936 type and calling its open routine. This is used for initiating
4937 communication with a particular target, in a generic way.
4939 * tm-i960.h: Update for modern gdb. Remove semicolons from
4940 various macros. Handle reading struct return convention, and
4941 error-out attempts to return structs with the "return" command.
4942 Be sure gdb doesn't think we know how to call functions in the
4945 * i960-tdep.c: Rename FRAME_CHAIN_VALID and FRAME_FIND_SAVED_REGS
4946 to i960_xxx in lower case.
4947 (arg_address): Circumvent errors due to LOC_ARG_BLOCK
4948 not being defined yet.
4950 * remote.c (remote_open): Call start_remote to initialize
4951 wait_for_inferior during open.
4952 (remote_xfer_inferior_memory): Return length written rather
4955 * remote-vx.c (target_command -> vx_open): Use new generic
4957 * remote-eb.c, inftarg.c, exec.c: ditto.
4959 * infrun.c: Fix comments.
4960 (attach_program -> child_open): Use new generic target command.
4961 (wait_for_inferior): Clear saved register values before target_wait,
4962 so target_wait can set some of them if convenient.
4964 * infptrace.c (fetch_inferior_registers, store_inferior_registers):
4965 Return success indicator, not void.
4966 (child_xfer_memory): Avoid fetching initial word if we'll
4967 overwrite it anyway.
4969 * infcmd.c (attach_command): Use new generic target open routine.
4970 (_initialize_infcmd): Update doc on attach and detach commands.
4971 (do_registers_info): Merge in a byte-order problem as a FIXME
4974 * findvar.c (find_saved_register): Avoid problem in current frame.
4975 (read_relative_register): Ditto.
4976 (write_register): Convert byte order on the way out.
4978 * exec.c (file_command): Add.
4979 (add_to_section_table, exec_command): Use new bfd_map_over_sections.
4980 (xfer_memory): Common function between core_xfer_memory and
4982 (exec_xfer_memory): Use it.
4984 * pn-opcode.h: Document that a "PN" is a Gould PowerNode.
4986 * breakpoint.c, breakpoint.h, symtab.h, value.h, frame.h, utils.c,
4987 valops.c, stack.c, target.c, sparc-xdep.c, source.c, printcmd.c,
4988 infcmd.c, i960-pinsn.c, eval.c, defs.h: lint and gcc -Wall.
4990 Sun Dec 2 16:45:06 1990 John Gilmore (gnu at cygnus.com)
4992 Merge Intel 960 port of gdb, continuing...
4994 * dbxread.c (partial_symbol_file_open, partial_symbol_file_read,
4995 symbol_file_command): Pass from_tty arg to hush 'em up.
4997 * coffread.c (symbol_file_command): Avoid output if from_tty != 1.
4998 Add magic numbers for 960 COFF format.
5000 Fri Nov 30 09:18:20 1990 John Gilmore (gnu at cygnus.com)
5002 Merge Intel 960 port of gdb, from Intel "1.2" release.
5004 CHANGE_LOG entries from their port, which was based on
5007 Thu Sep 6 11:02:22 PDT 1990
5008 Remove temp file if download is interrupted.
5010 Wed Aug 1 09:08:33 PDT 1990
5011 Now uses binary protocol to talk to NINDY.
5012 Old hex protocol (NINDY 2.13 and older) supported with -O switch.
5013 Times out after 5 seconds when trying to talk to NINDY.
5015 Tue May 29 12:54:49 PDT 1990
5016 Added variable baud rate (-b switch).
5017 Source code reorganization.
5019 Thu Apr 26 11:09:55 PDT 1990
5020 More cleanup of batch mode; specifically, execute "-s", "-e", and
5021 "-se" switches as soon as they are encountered on the invocation line.
5023 Fri Apr 20 13:47:15 PDT 1990
5026 Thu Apr 19 09:54:28 PDT 1990
5027 Add 'reset' command.
5029 Wed Apr 18 09:48:07 PDT 1990
5030 After opening remote tty, wait for 1 second to go by without input
5031 from it before trying to talk to NINDY (fixes problems with the
5032 Heurikon HK80/V960E).
5034 Mon Apr 4 16:33:05 PDT 1990
5035 Some output was not being suppressed in 'batch' mode.
5037 Thu Mar 22 15:31:11 PST 1990
5038 Ask user if old symbol table should be deleted when new file is
5041 Allow user to run a program downloaded before gdb960 was brought up.
5043 Correct "exec-file" help message for i80960 context.
5045 Correct bug in calculating user space address: could occasionally
5046 corrupt user program.
5048 Make sure to zero low-order bits in rip's because of bug in 960CA
5049 A-step part: could cause operation faults when "next"ing across
5052 Correct bug that made it impossible to get source line numbers for
5053 code loaded at addresses higher than 0x7fffffff.
5055 Wed Jan 10 12:43:22 PST 1990
5056 Open remote tty for exclusive use.
5058 Fri Jan 5 12:14:42 PST 1990
5059 Correct disassembly (CA manual was right after all):
5060 opcode for sysctl is 0x659
5062 Mon Oct 23 12:03:04 PDT 1989
5063 Use G960BASE and G960BIN environment variables to find 'sx' utility.
5065 Mon Oct 16 14:15:09 PDT 1989
5066 "sfr0"-"sfr31" should have been named "sf0"-"sf31"
5068 Mon Oct 2 15:56:31 PDT 1989
5070 Added 960CA disassembly support.
5072 To simplify maintenance:
5073 - eliminated use of symblic links on pinsn.c: use i960-pinsn.c
5075 - eliminated opcode.h: incorporates tables into i960-pinsn.c
5076 - moved 960-specific routines from i960-pinsn.c to i960-md.c
5077 - made disassembly interface identical to that in gdmp960.
5081 Wed Nov 28 21:32:48 1990 John Gilmore (gnu at cygint)
5083 * target.h: Allow targets to stack. Add target_has_memory,
5084 _registers, etc. Restructure memory access and "info files"
5085 to walk the target stack.
5086 * exec.c, core.c, inftarg.c, remote.c, remote-vx.c, remote-eb.c,
5087 target.c: Change tables to match target.h.
5088 * inflow.c (child_mourn_inferior): pop child_ops.
5089 (generic_mourn_inferior): Use new has_stack flag.
5090 * infptrace.c (child_xfer_memory): New memory regime.
5091 * inftarg.c (child_files_info): New "info files" regime.
5092 * remote-eb.c: New memory regime, new info files.
5093 * remote-vx.c: New memory regime, new info files. Now use
5094 separate targets for VxWorks attachment to machine, and
5095 actually running a process under VxWorks, since one has
5096 stack & execution & regs and the other doesn't.
5097 * remote.c: New memory regime, new info files.
5098 * sparc-xdep.c (fetch_core-registers): New memory regime.
5099 * target.c: New routines and support for stacked targets,
5100 new memory regime, new info files regime.
5103 Generalize section handling for an arbitrary number of sections,
5104 including use of the new BFD (binary file) library.
5105 * gdbcore.h: Add struct section_table.
5106 * exec.c (build_section_table): Iterate all sections and
5107 record what gdb needs to know about them.
5108 (exec_command): Use it.
5109 (exec_xfer_memory): Use the table.
5110 (exec_files_info): Print the table.
5111 * core.c (core_file_command, core_xfer_memory, core_files_info):
5113 * source.c (find_source_lines): Use bfd_get_mtime.
5114 * dbxread.c: Quick changes to make it compile with new BFD.
5115 * utils.c (error): Avoid using bfd_error in generic routines.
5117 * core.c (core_fetch_registers): Get from the ".regs" section of
5119 * sparc-xdep.c (fetch_core_registers): Use the .regs info.
5121 * inferior.h (attach_flag): Export.
5122 * infcmd.c (run_command): use new target_create_inferior.
5123 * infrun.c (child_create_inferior): Don't return result.
5124 * Makefile.dist (VERSION): 3.91.4.
5126 Fri Nov 23 28:15:38 1990 John Gilmore (gnu at cygint)
5128 * breakpoint.c (bpstat_num): Handle breakpoints which have
5129 since been deleted, such as temporary breakpoints.
5130 infcmd.c (program_info): ditto.
5132 * core.c (core_file_command): Display the frame where the core
5137 * remote-vx.c (target_command): Merge in target command from
5138 targ-vx.c. A few other cleanups.
5140 * TODO, Projects: Lots more stuff to do...
5142 Fri Nov 23 18:15:38 1990 John Gilmore (gnu at cygint)
5144 Massive changes to wall off the remote-debugging interface
5145 behind a function vector. The port to handle VxWorks targets
5146 is also part of this.
5148 All files: Replace references to renamed functions,
5149 remove references to remote_debugging, remove references to
5150 have_include_file, have_core_file in favor of target_has_stack,
5151 target_has_memory, etc.
5153 * Modularize the breakpoint interface.
5154 breakpoint.h (BREAKPOINT_MAX): New define sets max length of
5155 a breakpoint instruction.
5156 breakpoint.c: struct breakpoint's shadow_contents now sized as
5158 (insert_breakpoints): Vector to target to install breakpoints.
5159 (remove_breakpoints): Vector to target here too.
5160 Remove REMOTE_SA_SPARC kludges and other remote_debugging.
5161 sparc-tdep.c (single_step): Use new breakpoint interface for
5162 the single-step breakpoints.
5163 mem-break.c (memory_insert_breakpoint, memory_remove_breakpoint):
5164 New file, contains routines to insert and remove breakpoints by
5165 reading out the old contents and later replacing them. This is
5166 how ptrace breakpoints work, and many remote systems as well.
5168 * tm-vxworks68.h: New config file, overrides a few things for
5169 Wind River's preferences.
5171 * target.h: New file, for transfer vector used to talk to the
5172 inferior (child, attached, core, exec, remote, etc). All accesses
5173 to the thing being debugged should come through these vectors.
5174 target.c: New file, routines to handle transfer vector.
5175 (various files): Add transfer vectors XXX_ops for the various
5176 targets and pseudo-targets (core files, etc) we support.
5178 * breakpoint.c (bpstat_stop_status): Further explorations of
5179 watchpoints and why things don't work all the time.
5180 (bpstat_alloc): New fn to allocate a bpstat and chain it.
5182 * config.gdb: Only add "source ${srcdir}/.gdbinit" to
5183 the local gdbinit if it doesn't already have it.
5185 * core.c (core_ops): add and install.
5186 Allow core debugging without exec file.
5188 * dbxread.c (free_and_init_header_files): Merge two fns.
5189 (end_symtab): Free named symbol table when a new version comes in.
5190 (read_dbx_symtab): Relocate all kinds of symbols with base
5191 address. First step toward handling different text, data, bss
5193 (add_file_addr_command): Renamed add_file_command.
5194 (add_file_command): Vector to remote handler.
5195 Add "load" as an alias for "add-file" command.
5197 * defs.h: Allow "volatile" to be used in non-ANSI; use it for
5198 non-returning functions.
5200 * exec.c: Add exec_ops, and push it as a target when an exec
5203 * infcmd.c (run_command): Pass executable file name and arg list
5204 separately when starting an inferior. Permit "run" when no exec
5205 file is specified, for VxWorks.
5206 (detach_command): Move to child_detach in inftarg.c.
5208 * inftarg.c: New file. Unix-child-specific routines, and the
5209 child_ops structure.
5211 * inferior.h (registers): Export "registers" as the way for
5212 target dependent register handlers to find gdb's local copy of
5213 the registers. Rename "stop_after_attach" to "stop_soon_quietly"
5214 since it is now used by places that want wait_for_inferior to
5215 handle the grunge but want to see every trap from the inferior.
5217 * inflow.c (create_inferior): Pull out, and merge into infrun.c.
5218 Eliminate remote_debugging hooks in terminal handling.
5220 * infrun.c: Replace start_inferior with child_create_inferior.
5221 Move all the hair of Unix shells and ptrace idiosyncracies into
5222 child_create_inferior, so remote handlers don't have to deal.
5223 Remove running_in_shell. Rename stop_after_attach to
5224 stop_soon_quietly, and use it in a few other places where we want
5225 to just call wait_for_inferior and get control back on the first
5226 trap. trap_expected now never takes a value > 1.
5227 (init_wait_for_inferior): Initialize static vars when a new
5230 main.c (gdbinit): Add new hook for .gdbinit file name, let
5231 it be overridden by config files as GDBINIT_FILENAME.
5232 (DEFAULT_PROMPT): Add new hook for overriding (gdb) prompt.
5233 Both of these are used for VxWorks gdb.
5235 mcheck.c: rename include file "gmalloc.c" to avoid problems
5236 with system include file "malloc.c".
5238 param-no-tm.h: New include file, same as param.h but does not
5239 include the default "tm.h" file. This is used in files where
5240 the target is known, e.g. remote-eb.c or sparc-xdep.c.
5242 param.h: Now just a shell that includes tm.h and param-no-tm.h.
5244 remote-vx.c: New file, VxWorks remote debugging support. Uses
5245 RPC routines that are shared with the target system, in directory
5248 remote.c: Vectorize remote interface.
5250 source.c: Globalize source_path, and make an alias "l" for "list"
5251 since we now have the "load" command.
5253 sparc-xdep.c: Use new param-no-tm.h.
5255 symmisc.c (free_named_symtab): Add new function from Wind River.
5256 However, ifdef it out for now while we think about what it should
5259 tm-sun3.h, xm-sparc.h, xm-sun3.h, xm-symmetry.h: Move
5261 the xm- file, and change its name to CHILD_PREPARE_TO_STORE, since
5262 non-Unix-children handle this with their own code in the target
5265 Makefile.dist: Roll version to 3.92.3. Add vx-share stuff to
5266 source and target lists. Add vx-share to default list of include
5267 directories. Add new files to src and target lists: mem-break,
5268 target, inftarg, remote-eb, remote-vx, targ-vx. Be sure the
5269 ${srcdir} versions of munch and createtags are used.
5271 * valops.c (find_function_addr): Split out of call_function.
5272 (call_function_by_hand): Rename call_function; this function
5273 calls functions in the target by laboriously patching the target
5274 word-by-word with the right stack, args, regs, etc.
5277 Mon Nov 5 17:29:10 1990 John Gilmore (gnu at cygint)
5279 Handle AMD 29000 a bit better.
5281 * remote-eb.c (readchar): Mask received char log to make it readable.
5282 (remote_start): Pass arguments down to executing program.
5283 Make startaddr unsigned.
5284 infrun.c (start_inferior): Accept args, pass them to
5286 infcmd.c (run_command): Pass args down to start_inferior.
5288 * tconfig/am29k-aout, tconfig/am29k-coff: New files specifying
5289 the target object file format.
5290 tm-29k.h: Pay heed to COFF_ENCAPSULATE.
5292 * am29k-pinsn.c (print_insn): Print 0x on hex numbers in disassembly.
5293 am29k-tdep.c (examine_prologue): Better checking of function prefixes.
5295 Sun Oct 7 18:20:45 1990 John Gilmore (gnu at cygint)
5297 * Makefile.dist (VERSION): Roll version to 3.91.9 and freeze.
5298 * TODO: We did a few things, we have more to do though.
5300 * xm-sparc.h (CLEAR_DEFERRED_STORES): Define.
5301 * inflow.c (inferior_died): Clear deferred stores.
5303 * Debug problems with dummy frames and calls to the inferior.
5304 * tm-sparc.h (PUSH_DUMMY_FRAME, POP_FRAME): Move to sparc-tdep.c.
5305 * sparc-tdep.c (do_restore_insn): Simplify.
5306 (sparc_frame_find_saved_regs): Simplify and fix what we find.
5307 (sparc_push_dummy_frame): Simplify and fix what we push.
5308 (sparc_pop_frame): Slightly more hair here, deciding whether
5309 we are restoring a saved PC or returning to a return address in %i7.
5310 * sparc-xdep.c (read_inferior_registers): Debug if valid reg is read.
5312 * utils.c (xmalloc, xrealloc): Return type depends on __STDC__.
5313 * symtab.h (xmalloc): ditto, for obstack_chunk_alloc.
5314 * obstack.h (chunkfun): ditto.
5315 * defs.h (xmalloc, xrealloc): ditto
5317 * utils.c (quit): Grab the terminal from the child if necessary.
5319 * inflow.c (term_status_command): Rename to term_info, change
5322 * sparc-pinsn.c (print_insn): Disassembly prefers real instructions.
5323 (is_delayed_branch): Speed up.
5324 * sparc-opcode.h: Add ALIAS bit to aliases. Fix up opcode tables.
5325 Still missing some float ops, and needs testing.
5327 * Support for input and output radixes other than base 10
5328 * defs.h (input_radix, output_radix): Declare.
5329 * expread.y (yyparse, parse_number): Handle changes of input
5330 radix, and ambiguous names-or-numbers in radixes >10.
5331 * printcmd.c (print_scalar_formatted): Print formatted hex
5332 numbers in varying column widths.
5333 * valprint.c (val_print): Use output_format to print scalar ints.
5334 (set_input_radix, set_output_radix, set_radix): Create.
5335 (set_output_radix): Set output_format from output_radix.
5336 (_initialize_valprint): add `set radix' but leave the others off.
5338 * main.c (execute_command): Let stupid questions be turned off.
5339 (_initialize_main): Handle "set stupidity", etc.
5341 * main.c, inflow.c, inferior.h, frame.h, command.c, defs.h,
5342 sparc-pinsn.c, sparc-xdep.c, value.h, valops.c, values.c: Lint.
5344 Tue Oct 2 11:20:02 1990 John Gilmore (gnu at cygint)
5346 * TODO, Makefile.dist, ChangeLog: Freeze for 3.91.8 release.
5347 bfd stuff is still screwed up, but with some manual work, it
5350 * breakpoint.c (bpstat_do_actions): Start over if a command
5351 proceeds the inferior, since the inferior will have stopped and
5352 will need to have its new stop-actions taken care of.
5354 * dbxread.c (read_struct_type): Expression gives Sun3 4.0.3
5355 compiler fits, simplify it.
5357 * gdb.texinfo (directory command): Doc new dir command.
5358 source.c (directory_command): "dir" now puts things on the front
5359 of the path, moves dups up front, and handles multiple names
5360 on the command line, inserting each one in order. It also
5361 blows away cached line and full_filename info.
5363 * stack.c (backtrace_command): Skip "more stack frames follow"
5366 * Change #ifndef HAVE_VPRINTF to #define MISSING_VPRINTF in
5367 xm-convex.h, xm-hp300bsd.h, xm-isi.h, xm-merlin.h, xm-news.h,
5368 xm-np1.h, xm-pn.h, xm-pyr.h, xm-symmetry.h, xm-umax.h, xm-vax.h.
5369 The only odd one was Gould NP1, which had defined vprintf to
5372 * Merge Ted Goldstein <tedg@Eng.sun.com>'s changes for epoch.
5373 printcmd.c (print_command_1): Pass 'inspect' flag down as a global
5374 variable, inspect_it.
5375 valprint.c (print_string, val_print): Use the global inspect_it
5376 to indicate whether to print in Epoch style or normal style.
5378 Mon Oct 1 23:55:26 1990 John Gilmore (gnu at cygint)
5380 * printcmd.c (call_command): add an alias for the "print" command
5381 which runs expressions and doesn't print the result if void.
5382 (print_command_1): implement it.
5384 * command.c: Remove #if 0'd code. Initialize all the fields
5385 in add_cmd (). Rename do_nothing_command to
5386 not_just_help_class_command, and make it externally visible.
5387 command.h: add user_commands to struct.
5388 * main.c (define_command): Don't overload c->function with a char
5389 string as well as a function pointer.
5391 * eval.c (evaluate_subexp): Reinstall tiemann changes to
5392 calling convention of value_struct_elt () that got dropped in
5395 * tm-sparc.h (FRAME_FIND_SAVED_REGS): move to sparc-xdep.c.
5396 sparc-tdep.c (sparc_frame_find_saved_regs): ditto.
5398 * tm-sparc.h (POP_FRAME): replace some constants with defines.
5400 * sparc-xdep.c (store_inferior_registers): defer stores to regs
5401 until a good time (e.g. when we are about to run the child),
5402 saving ptrace calls.
5403 * infrun.c (proceed): handle DO_DEFERRED_STORES.
5404 * tm-sparc.h: define DO_DEFERRED_STORES.
5406 * sparc-xdep.c (store_inferior_registers): when storing float
5407 registers, don't store stack regs too. When storing the SP,
5408 however, DO store the stack regs too. This fixes a bug in which
5409 the dummy frame is not recognized when a call_function finishes,
5410 because its frame pointer (in the stack regs) was never
5412 (read_inferior_registers): Mark WIM and TBR and FPS and CPS valid
5413 even though we don't know how to read them from an inferior.
5414 valops.c (call_function): Comment about storing SP.
5416 * infrun.c (save_inferior_status): Save away the original bpstat
5417 chain so it can be restored later. Install the copied version for
5418 use by whoever saved the status. It will be blow away by
5419 restore_inferior_status, and the original chain restored. This is
5420 important for people who have pointers into the original.
5422 * breakpoint.c, command.h, copying.awk, dbxread.c, defs.h,
5423 findvar.c, frame.h, obstack.h, obstack.c, inflow.c, value.h,
5424 main.c, printcmd.c, sparc-tdep.c, symtab.c, valprint.c: lint
5427 Fri Sep 28 20:32:46 1990 John Gilmore (gnu at cygnus.com)
5429 * Makefile.dist: Roll version to 3.91.8. Add bfd.h and bfdconfig.h
5430 temporarily to the makefile. Add am29k-opcode.h and WHATS.NEW.
5431 Add stuff.c and kdb-start.c to the OTHERS list for tar files.
5433 Fri Sep 28 19:12:12 1990 John Gilmore (gnu at cygint)
5435 * Merge Mike Tiemann's multiple inheritance changes from Sun.
5436 Store the baseclasses in a type struct starting from array element
5437 0 rather than from the unusual array element 1.
5439 dbxread.c: the above.
5440 (virtual_context): Add
5441 Read new debug information about which virtual function table
5442 a virtual function is from, and store it in fn_field.fcontext.
5444 symtab.h: Add fcontextt. Fix baseclass indices. Typo in
5445 TYPE_FN_FIELD_STATIC_P.
5447 symtab.c: the above.
5448 valops.c: the above. Handle pointer casts of object *'s.
5449 (search_struct_method): Add.
5450 (value_struct_elt): First arg is now a pointer to a value, and is
5453 valprint.c: the above.
5454 values.c (value_virtual_fn_field): Add type arg. Handle
5455 offsetting to the proper object when calling virtual fns.
5457 (baseclass_addr): Add valuep arg.
5459 * README: Document the current state of BFD config (missing).
5460 * TODO, ChangeLog, Makefile.dist: Roll version.
5461 * WHATS.NEW: Add summary of changes since 3.5.
5463 Thu Sep 27 16:23:12 1990 John Gilmore (gnu at cygint)
5465 * dbxread.c (read_struct_type): Clear bit vectors whenever
5467 symtab.c (B_CLRALL): define.
5469 * tm-sparc.h (STORE_RETURN_VALUE): Avoid clobbering types by
5470 using == rather than =. Huh... This fixes the dreaded problem
5471 wherein builtin_type_int becomes TYPE_CODE_FLT.
5473 * core.c (info_files): Show the inferior pid.
5475 * config.gdb: Avoid putting "dir" command into .gdbinit. GDB
5476 already knows how to look in the source directory.
5478 * Remove psymtab hair from many places. Remove duplicated code
5479 for searching symbol tables. Hide psymtabs from most places.
5480 Make it fast to get from a psymtab to its symtab.
5482 blockframe.c (blockvector_for_pc): Remove psymtab hair.
5483 coffread.c (psymtab_to_symtab): Rename to psymtab_to_symtab2.
5484 mipsread.c (psymtab_to_symtab): Rename to psymtab_to_symtab2.
5485 dbxread.c: export psymtab_to_symtab, make it work if called N times.
5486 (psymtab_to_symtab): Rename to psymtab_to_symtab2. Initialize
5487 new symtab completely. New psymtabs get symtab pointer
5488 initialized to zero. Remove MI warning printf.
5489 symtab.h: Comments. Add psymtab to symtab pointer.
5490 (PSYMTAB_TO_SYMTAB): New macro.
5491 symtab.c: use PSYMTAB_TO_SYMTAB. Add psymtab_to_symtab and export it.
5492 source.c: use PSYMTAB_TO_SYMTAB. Remove symtab version and
5494 stack.c (backtrace_command): Avoid pre-pass to read symbols, if
5496 (print_frame_info): Avoid special-casing symbols that have not yet
5499 * source.c (open_source_file): Quick path if we have already
5500 located the source file by its full name.
5502 * symtab.c (lookup_symbol): Use find_pc_symtab rather than
5503 find_pc_psymtab. When a name is found in the misc function
5504 vector, search the symbol table for its mangled name, not the
5505 name that the user typed.
5507 * bfd.h: Fix missing comment terminators, make #endifs match.
5509 * valarith.c (value_less): Handle unsigned int comparisons.
5510 Add FIXME about pointer compares, which assume host and target
5511 pointers are the same.
5513 * command.c (do_nothing_command): lint
5514 dbxread.c: lint. Remove sort_syms. Document C++ visibility info,
5515 fix comments on debug symbol format for visibility. Actually set
5516 visibility of symbols.
5517 main.c (echo_command): lint; use <readline/history.h>.
5518 tm-sparc.h (FRAME_FIND_SAVED_REGS): lint
5519 obstack.h (_obstack_blank): Rearrange pointer math to avoid
5520 pointing past end of allocated memory; saber complains.
5521 obstack.h: Declare the external functions that we use.
5522 valarith.h: use <string.h>
5523 solib.c (solib_add): lint.
5525 Fri Sep 21 17:05:19 1990 John Gilmore (gnu at cygint)
5527 * main.c (initialize_main): Default info_verbose to off, now that
5528 symbol reading is fast.
5529 (quit_command): Avoid clobbering exec_bfd while quitting.
5531 * Initial BFD (binary file diddling library) merger:
5532 coffread.c: Change AOUTHDR to struct exe_hdr.
5534 core.c: initialize initialized data at compile time.
5535 (core_file_command): Move from coredep.c, convert to bfd.
5536 (xfer_core_file): Convert to bfd.
5537 exec.c (exec_file_command): use bfd routines.
5539 mips-tdep.c: Remove exec_file_command and friends.
5542 * coredep.c: (fetch_core_registers) Convert core_file_command to
5543 fetch_core_registers.
5544 mips-xdep.c, sparc-xdep.c, sun3-xdep.c: ditto.
5546 * utils.c: (error): Bogus crap, FIXME, to print bfd errors.
5547 (my_bfd_read): More bogosity, which I don't think we call.
5548 (program_name): Remove this atrocity asap!
5550 Wed Sep 19 13:36:41 1990 John Gilmore (gnu at cygint)
5553 values.c: allocate_repeat_value was not clearing the
5554 optimized_out field.
5555 (value_static_field): minor stylistic fix (wrong macro was used).
5556 valops.c (value_struct_elt_for_address): didn't work for C++
5559 * signame.c (_initialize_signame): Initialize signal names once.
5561 * breakpoint.h, command.c, copying.awk, defs.h, environ.c,
5562 exec.c, frame.h, infcmd.c, inferior.h, main.c, munch, sun3-xdep.c,
5563 symtab.h, tm-29k.h, valprint.c, value.h, values.c: Lint.
5565 * remote-eb.c: Support user-settable baud rates on the serial port.
5567 * tm-sun3.h (PREPARE_TO_STORE): fix typo.
5569 Fri Sep 14 13:28:29 1990 John Gilmore (gnu at cygint)
5571 * tconfig/sun3os4: Remove warning about native assembler,
5572 since it also occurs in the xconfig file.
5574 * findvar.c (registers): Allocate some slop after `registers'
5575 to prevent stray accesses from trashing the next variable.
5577 * tm-68k.h (REGISTER_BYTES): Allocate the right number of bytes
5578 on the sun-3, by changing the #ifdef from `sun3' (which is not
5579 defined by cc) to `sun'. Symptom was trashed builtin_type_XXX
5580 vars, which happened to follow `registers' in the executable.
5582 * readline/history.c (history_search): Heed gcc-2's advice
5583 and parenthesize && inside ||).
5585 * am29k-opcode.h, am29k-pinsn.c, am29k-tdep.c, remote-eb.c,
5586 tm-29k.c: Insert FSF copyright headers.
5588 * remote-eb.c: Better comments.
5590 * Makefile.dist: Update to 3.91.6.
5591 * TODO: note PREPARE_TO_STORE problem.
5593 Thu Sep 13 09:52:33 1990 Jim Kingdon (kingdon at cygint)
5595 * stack.c (frame_info): Only use FRAME_FIND_SAVED_REGS if defined.
5597 * remote.c: Wrap the whole file in #if !defined (SPECIAL_REMOTE).
5599 * infrun.c (wait_for_inferior, at end): Don't set up
5600 prev_* if the inferior no longer exists.
5602 * inferior.h (CALL_DUMMY_LOCATION): New macro, to replace
5603 CANNOT_EXECUTE_STACK.
5604 valops.c (call_function): Use it.
5606 * tm-convex.h: Add CALL_DUMMY_LENGTH for use by PC_IN_CALL_DUMMY.
5608 * inferior.h (PC_IN_CALL_DUMMY): New macro.
5609 infrun.c (wait_for_inferior, 2 places): Use it.
5611 * values.c (value_being_returned): Only use
5612 EXTRACT_STRUCT_VALUE_ADDRESS if defined.
5614 * Move PREPARE_TO_STORE from xm-sun3.h to tm-sun3.h to do the
5615 right thing for remote-eb.c.
5617 * sun3-xdep.c: Remove extraneous call to remote_store_registers.
5618 * sun386-xdep.c, hp300hpux-xdep.c, sparc-xdep.c: Ditto.
5620 * blockframe.c: Put get_frame_saved_regs inside #if !defined
5621 (FRAME_FIND_SAVED_REGS).
5623 * findvar.c ({fetch,store}_registers): Check for
5624 REMOTE_{FETCH_STORE}_REGISTER macro.
5626 * findvar.c (get_saved_register): Add argument lval and
5627 change meaning of argument addr.
5628 findvar.c: Change calls to get_saved_register to reflect
5629 new calling convention.
5630 valops.c (value_assign): Use get_saved_register instead of
5631 find_saved_register.
5633 Sun Sep 2 12:40:20 1990 Jim Kingdon (kingdon at cygint.cygnus.com)
5635 * coffread.c (read_one_sym): Make temp_aux an AUXENT, not
5636 an (uninitialized) pointer to one. Use "&" when passing it
5639 Fri Aug 31 22:57:54 1990 Jim Kingdon (kingdon at cygint.cygnus.com)
5641 * coffread.c (getfilename): Use DGUX x_offset and x_name if
5644 * coffread.c (symbol_file_command): Put semicolon after
5646 Put safe_to_init_tdesc_context in #if defined (TDESC).
5647 Put #ifdef TDESCs in 1st column for non-ANSI cpp's.
5648 coffread.c: #include <sys/stat.h>.
5649 (read_coff_symtab): Typo: in_source_files -> in_source_file.
5650 Add missing ')' in check for "lc%" and friends. Remove
5652 Declare read_one_sym() at top of file.
5653 (read_file_hdr): Put in extra #ifdefs so MC68MAGIC and
5654 MC68WRMAGIC can have the same value without causing a duplicate
5657 Thu Sep 13 15:55:36 1990 John Gilmore (gnu at cygint)
5659 * Allow a Makefile to be built without building the
5660 tm and xm file links that screw up builds in subdirectories.
5661 This is done with `config.gdb none', then you can do things
5662 like `make gdb.tar.Z'.
5663 * tconfig/none: Config file for no target system
5664 * xconfig/none: Config file for no host system
5665 * config.gdb: If no TM or XM files are called out by the
5666 host or target file, don't make links for them.
5668 * cplus-dem.c: Add documentation.
5670 * dbxread.c (read_ofile_symtab): Turn a fatal error into a
5671 simple error, so the user's gdb doesn't crash due to some object
5672 file problem (e.g. somebody is rebuilding the file out from under
5675 * printcmd.c (print_address_symbolic): demangle the symbol.
5677 * Makefile.dist (OTHERS): Remove tdesc-lib because it has
5678 Motorola copyrights in it. Make "make gdb.tar.Z" work.
5679 (alldeps.mak): sort and uniq all results from this; duplicates
5680 hose gdb.tar.Z link building. Remove RCS files from
5681 tconfig and xconfig. Add config files for sun386. Add
5682 a few odd files to OTHERS and HFILES.
5684 Mon Sep 10 21:20:24 1990 John Gilmore (gnu at cygint)
5686 * Makefile.dist: Pull solib.c to tconfig/sun?os4.
5687 Roll version number to 3.91.5. Make lint work in bindir.
5689 * README: Document cross-debugging and new file structure.
5691 * blockframe.c: Lint. Include "value.h" to declare read_register.
5692 (find_pc_partial_function): remove duplicate line.
5694 * command.h: Lint. Declare error_no_arg and dont_repeat.
5696 * tm-news.h: Remove inadvertently duplicated stuff.
5698 * mipsread.c: Remove cache_pc_function stuff, now done cleanly.
5699 Clean up usage of misc_function_type. Declare some CORE_ADDRs.
5701 * config.gdb: Allow `config.gdb host target' form. Clean
5702 up previous change that printed bogus messages when you just said
5705 * core.c: #include "command.h" for lint.
5708 * main.c: Remove some casts of enums. Lint.
5715 * printcmd.c (initialize_printcmd): Fix thinko in inspect cmd.
5717 * sparc-tdep.c (isannulled): Take instruction as parameter, don't
5718 read it from memory. This will allow us to save ptrace calls
5719 eventually. Changed caller single_step too.
5721 * sparc-xdep.c (fetch_inferior_registers): Avoid reading regs
5722 that we aren't going to use, saving many ptrace calls, especially
5723 when watchpointing or single stepping. Use some #define's for
5725 (store_inferior_registers): Ditto.
5726 (core_file_command): Use some #define's for constants.
5728 * tm-sparc.h: Add #define's for some register numbers, so we
5729 can eliminate the use of random constants in sparc-xdep.c.
5731 * stack.c (frame_command, print_frame_info, up_command,
5732 down_command) Remove frame_changed, since it
5733 causes a bug and doesn't seem to do anything useful. In some
5734 places it was used as a flag, in others as a stack level (?).
5736 * utils.c: Use MISSING_VPRINTF rather than HAVE_VPRINTF, so the
5737 default is to use the portable (vprintf) version rather than the
5739 * xm-news.h (MISSING_VPRINTF): Add.
5741 * valprint.c (val_print): Demangle fancy vtbl printouts. Lint.
5743 Sat Sep 8 00:24:12 1990 John Gilmore (gnu at cygint)
5745 * Remove stuff that forces -Bstatic linking of gdb, and warnings
5746 about linking debugged programs -Bstatic in the sun?os4 config
5747 files in tconfig and xconfig subdirectories.
5749 * main.c (main): Remove unreached exit(0) now that we exit
5752 * Create TODO file for online bug list. There are too many
5753 "little" bugs to keep track of on paper.
5755 * Change Projects file to refer to bug-gdb@cygnus.com
5756 rather than kingdon@ai.
5758 Fri Sep 7 23:35:15 1990 John Gilmore (gnu at cygint)
5760 * Makefile.dist (VERSION): 3.91.4 now.
5762 * symtab.c (init_misc_bunches): Rename from init_misc_functions.
5763 (condense_misc_bunches): Add sanity check that misc_count is
5764 the same as the number of symbols in the bunch.
5766 * coffread.c: rename init_misc_bunches. Pass an argument
5767 to condense_misc_bunches (a zero).
5769 * dbxread.c (partial_symbol_file_read): Call init_misc_bunches
5770 every time we are called; don't rely on our caller to do it.
5771 (add_file): Remove call to init_misc_bunches.
5773 * mipsread.c: Only warn, don't error, if unknown symbol types.
5774 This keeps an old gdb from falling on its face if it sees newly
5775 extended symbol info. Rename init_misc_bunches.
5777 Fri Sep 7 22:58:15 1990 John Gilmore (gnu at cygint)
5779 * Merge in changes from Per Bothner for DECstations and other
5780 MIPS stuff. The rest is Bothner speaking:
5782 The next message is a merger of Alessando Forin's mips port with
5783 mine. I've tried to use my good if biased judgment to get
5784 the best of both. It *does* need testing.
5786 Some of the changes are general, *not* mips-specific.
5789 Didn't believe in little-endian bit order.
5790 There are still inconsistencies about whether flags
5791 like BITS_BIG_ENDIAN are integer (#if ...) or
5792 boolean (#ifdef ...). I tried to paper over them.
5794 dbxread.c,coffread.c,mipsread.c,symtab.c,symtab.h:
5795 Moved some misc_function code that was common to
5796 {dbx,coff,mips}read.c to symtab.c.
5797 In the process, I think I cleaned things up a bit.
5798 At the same time, moved obsavestring and obconcat to symtab.c.
5801 Removed obsolete condense_addl_misc_bunches (use
5802 condense_misc_bunches(1) instead).
5805 Needed to include <sys/dir>, at least on DECstations.
5807 valops.c, mips-tdep.c, tm-mips.h:
5808 Added PUSH_ARGUMENTS macro to support funny argument-pushing
5809 conventions (when STACK_ALIGN is insufficient).
5810 Needed on mips, where doubles need 8-byte alignment,
5811 but ints only need 4.
5814 Removed cruft that was not being used.
5815 Merged in many fixes (most from Frank Yellin, fy@lucid.com).
5818 Print $ before register-names (I think that makes things a little
5820 Never print two instructions, even if one delays.
5821 Removed hex-disassemble set_cmd. (This is not mips-specific,
5822 so I think the argument is whether it is generally worthwhile or not.
5823 I'm inclined to think not, given how easy it is to
5824 convert between radixes in gdb.)
5827 This is basically Alessando's code.
5828 It doesn't use obstacks; I changed it to use obstacks
5829 in a few minor places where using malloc causes a
5830 memory leak. (Probably, more places could/should be changed.)
5831 I added record_misc_function where it was missing.
5832 In symbol_file_command and add_file_command, I tried
5833 to make the code consistent with more recent versions.
5834 Minor sylistic changes in parse_procedure.
5835 Make a .gdbinfo. psuedo-symbol point back to the real
5836 procedure symbol (using the isym field).
5839 This is basically from my port, but with a lot of details
5840 and a number of routines merged in from Alessando's version.
5841 I basically used my code "raw" backtrace (use heuristics
5842 from the actual code, rather than symbol table info) - though
5843 the idea is Alessandro's. I feel my code is a little cleaner
5844 here, particularly in being a little more flexible, such as being
5845 able to handle gcc-produced code (which it now can).
5846 It also doesn't do frame caching (which is not useful
5847 more recent gdb versions).
5848 I also used my code for push_/pop_dummy, more or less.
5849 I tried to incorporate AF's code for testing sigtramp
5850 while backtracing; I probably got it wrong.
5851 Added mips_print_register, which tries to scrunch as much
5852 information as possible on a screen...
5853 Removed the skip-prologue set_cmd. As with hex-disassemble (see
5854 under mips-pinsn.c), I don't see anything mips-specific here,
5855 and I don't see it being all that useful anyway.
5858 Added a $fp psuedo-reg distinct from $fp (nice for gcc).
5859 Use more register names (rather than hard-cases numbers).
5861 Thu Sep 6 18:33:15 1990 John Gilmore (gnu at cygint)
5863 * Hack up 3.90.11 changes:
5865 * Makefile.dist (depend): parameterize $(GCC).
5866 Add solib.c and solib.o.
5867 (readline): Fix vpath for both absolute or relative SRCDIR.
5869 * blockframe.c: Fix from Schaefer@asc.slb.com for shared libs.
5870 Also, let the part I didn't understand at least compile so
5871 I can test the rest. FIXME.
5873 * dbxread.c: Fix thinko using strcmp.
5874 (init_psymbol_list): declare static.
5875 (partial_symbol_file_open): Comment cleanups better, avoid
5876 cleaning up the string table since the caller will do that.
5877 Move the stat for mod time into symbol_file_command, temporarily.
5878 (There should be a mod time for each symbol file, eventually,
5879 to control its rereading. FIXME.)
5881 * infptrace.c (PT_WRITE_D): use same value as PT_WRITE_I for
5882 SunOS, which gives error for shared libs otherwise. (From
5883 Schaefer, probably FIXME needs work for portability.)
5885 * solib.c: Move #include "param.h" to work.
5886 Lowercase all the Uppercase Letters In the Messages.
5887 (find_solib): Clean up inferior_so_name for debug printouts.
5888 Allow no argument, to mean all shared libraries.
5890 * symmisc.c: include param.h to get CLEAR_SOLIB.
5892 Wed Sep 5 18:00:08 1990 John Gilmore (gnu at cygint)
5894 * Merge in Kingdon's changes from FSF: the diffs from 3.90.9

5903 Tue Jun 12 16:15:26 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5907 * Makefile.dist (gdb.tar.Z): Change linking of config so it works.
5909 Thu Jun 7 16:22:27 EDT 1990 Jay Fenlason (hack@ai.mit.edu)

5913 Mon Jun 4 18:12:31 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5915 * m-sparc.h (REG_STRUCT_HAS_ADDR, STRUCT_ARG_SYM_GARBAGE):
5916 Put parens around gcc_p in expansion.
5918 Thu May 24 15:44:51 1990 Jim Kingdon (kingdon at mole.ai.mit.edu)
5920 * utils.c (lines_to_list): Return 10 if lines_per_page == 0.
5922 Wed May 23 16:36:04 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5924 * Changes for Sun shared libraries:
5925 blockframe.c (find_pc_partial_function): If a non-text symbol
5926 is found, set *address = pc - FUNCTION_START_OFFSET.
5927 breakpoint.c (insert_breakpoints) [DISABLE_UNSETTABLE_BREAK]:
5928 Disable breakpoints instead of giving an error.
5929 source.c (select_source_symtab): Initialize cs_pst.
5930 symmisc.c: Call CLEAR_SOLIB if defined.
5931 symtab.h: Make text{low,high} CORE_ADDR not int.
5932 (psymtab): New field addr.
5934 dbxread.c: Move DECLARE_FILE_HEADERS outside functions.
5935 (record_misc_function): Give correct type for N_DATA symbols.
5936 (condense_misc_bunches): do "misc_function_count = j" regardless
5938 Take code which is shared between symbol_file_command and
5939 add_file_command and put it into partial_symbol_file_{open,read}.
5940 Split add_file_command into add_file_command and add_file.
5941 Make psymtab_to_symtab read in the string table if the file
5943 Two new parameters to read_dbx_symtab and start_psymtab.
5944 tm-sunos.h: New file.
5946 Tue May 22 17:43:03 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5948 * infcmd.c: Change cont_command to continue_command and "cont"
5951 Mon May 21 14:41:41 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5953 * breakpoint.c (enable_breakpoint): Get value of watchpoint.
5955 * defs.h [sparc]: Use <alloca.h> regardless of __GNUC__.
5957 * values.c (USE_STRUCT_CONVENTION): Check for structures of
5958 size 1,2,4,8 rather than size < 8.
5960 * dbxread.c (dbx_lookup_type): Do f->length *= 2 as many times
5961 as necessary, not just once.
5963 * sparc-opcode.h: Add a bunch of new opcodes which Sun as supports.
5965 Thu May 17 15:04:09 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5967 * {t,x}m-sun386.h, sun386-xdep.c, {x,t}config/sun386
5969 * tm-news.h: Add CALL_DUMMY_*.
5971 * tm-68k.h: Remove duplicate comment at FRAME_FIND_SAVED_REGS.
5973 * config.gdb: In list_host, list_target, use ${i}, not $i.
5975 Tue May 15 21:27:12 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5977 * source.c (find_source_lines) [BROKEN_LARGE_ALLOCA]: Use xmalloc.
5979 * sparc-opcode.h: Change all store floating-point state register
5980 instructions to have the right match & lose fields.
5982 Sat May 5 12:39:18 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5984 * Makefile.dist: Move -I${srcdir} to GLOBAL_CFLAGS and pass
5986 config.gdb: If srcdir != ., create readline directory and
5987 copy a makefile into it.
5989 * wait.h, infrun.c: Change WRETCODE to WEXITSTATUS for
5990 consistency with POSIX.
5992 * breakpoint.c (bpstat_stop_status): Disable watchpoint
5993 when we exit its exp_valid_block.
5995 Tue Sep 4 11:46:46 1990 John Gilmore (gnu at cygint)
5997 * Makefile.dist: Bump version to 3.91.3.
5999 * Clean up handling of breakpoint commands (somewhat).
6000 Prompted by Tiemann bug report "cont 10" doesn't work any more.
6002 inferior.h: Add breakpoint_proceeded to inferior status struct
6003 and globals; save it and restore it.
6004 (clear_breakpoint_commands): Cleanup, remove old #define.
6006 infrun.c (clear_proceed_status): Set breakpoint_proceeded.
6007 (save_inferior_status, restore_inferior_status): handle it also.
6008 (proceed): Remove earlier code that set breakpoint_proceeded.
6009 It is now set only in clear_proceed_status.
6010 (clear_proceed_status): Cleanup, use bpstat_clear rather
6011 than clear_breakpoint_commands. No callers need the stop_bpstat
6012 between clear_proceed_status and proceed.
6014 infcmd.c: Add breakpoint_proceeded definition and comment.
6015 (cont_command, jump_command, signal_command): Move call to
6016 clear_proceed_status right next to call to proceed.
6018 breakpoint.c (bpstat_do_actions): Avoid clobbering our
6019 caller's argument while running down the chain of breakpoints.
6020 Use new variable "breakpoint_proceeded" to determine when
6021 a command that it executes moves the inferior past the
6023 (bpstat_clear): Handle NULL argument.
6024 (bpstat_clear_actions): Avoid useless call to
6025 breakpoint_auto_delete.
6026 (delete_breakpoint): Clean up bpstat's that are pointing to
6027 the deleted breakpoint from the stop_bpstat chain.
6028 (breakpoint_auto_delete): Simplify.
6030 * Clean up handling of EOF, error on stdin, etc. This was
6031 prompted by a network problem that caused gdb to go into an
6032 infinite loop filling up its malloc'd memory.
6034 main.c (return_to_top_level): Cleanup: call bpstat_clear_actions,
6035 not clear_breakpoints_commands, which is now gone.
6036 (main): If command_loop returns (e.g. from EOF on stdin), do
6037 a quit_command (looping back to command_loop if quit_command
6038 doesn't really quit).
6039 (command_loop): check result from command_line_input and
6040 exit if it returns NULL, rather than passing the NULL to
6042 (gdb_readline): Free malloc'd result space before returning
6045 * utils.c (query): Handle C-d to mean "yes", just as if the
6046 input was not a terminal. Also avoid infinite loop if EOF
6047 occurs in mid-input-line before newline. This allows
6048 query to be used at EOF on stdin with reasonable results.
6050 * infrun.c (proceed): Set breakpoint_proceeded.
6052 * values.c (value_as_long): Avoid infinite recursion for enums.
6053 (_initialize_values): Fix typo in help msg (kingdon).
6055 * Makefile.dist (RL_LIB): Use RL_LIB_DEP for dependencies,
6056 RL_LIB for linking. This allows -lreadline for linking
6057 and nothing for dependencies, once readline is a real library.
6059 * config.gdb: Jim Kingdon: give useful error message if the
6060 host or target type is not recognized.
6062 * defs.h (alloca): SPARC <alloca.h> does not declare alloca,
6063 it just defines it. Dumb, but deal with it.
6065 * Jim Kingdon suggests:
6066 in xconfig/sun3os4, CFLAGS should be XM_CFLAGS.
6068 Wed Aug 29 18:03:27 1990 John Gilmore (gnu at cygint)
6070 * Makefile.dist (VERSION): Bump version # to 3.91.2.
6072 * Clean up Bothner's changes.
6074 * blockframe.c (clear_pc_function_cache): New function.
6075 * blockframe.c: remake cache_pc_function_* static.
6076 * dbxread.c (symbol_file_command): remove references to
6077 cache_pc_function_* variables.
6078 * dbxread.c (read_struct_type): Use VOFFSET_STATIC.
6079 * printcmd.c: Avoid kludging a global variable (addressprint)
6080 to avoid printing the address of a string twice. Instead,
6081 pass the format letter 's' down low enough that it can be seen
6082 to avoid this problem.
6083 (print_formatted): Pass format arg to value_print.
6084 (restore_addressprint): Remove function.
6085 (do_examine): Avoid hacking addressprint, cleanups and such.
6086 (print_frame_args): Add a comment to a Bothner change.
6087 * symtab.h: define VOFFSET_STATIC and use it instead of "-1".
6088 * symmisc.c (free_all_symtabs): Call clear_pc_function_cache
6089 to wipe out the values cached in blockframe.c.
6090 * symtab.c (find_method): Add comment saying how big you must
6091 allocate to be "big enough". Per being terse again.
6092 * valprint.c (val_print): Handle format letter "s" to print
6093 strings without addresses. Add comment to vtbl printing code
6094 which casts with wild abandon. Rearrange reference-printing
6096 @0xaddr: value (print w/addressprint)
6097 value (print w/~addressprint)
6098 @0xaddr (parameter lists w/addressprint)
6099 or nothing (parameter lists w/o addressprint)
6101 Tue Aug 28 10:47:18 1990 John Gilmore (gnu at cygint)
6103 * Merge more changes from Per Bothner:
6105 Gdb's handling of TYPE_CODE_REF was so counter-C++ (and otherwise
6106 annoying) that I tried to improve it. Here are my suggestions.
6108 These patches all attempt to handle TYPE_CODE_REF (as in C++) better.
6111 Do automatic de-reference when taking the address of a reference.
6113 Don't deref_ref when printing parameter lists.
6115 More attempts at treating refernences properly.
6117 In val_print, if deref_ref==0, don't print dangling " = ".
6119 Add COERCE_REF macro, which de-references an REF.
6121 * Merge changes from Per Bothner:
6123 * Fixed (Sony news)-specific configuration problems.
6124 * Fixed other problems with using vanilla pcc and libc (enum problems;
6125 assumption that vsprintf exists).
6126 * Some major speed-ups (finc_pc_partial_function now caches a match;
6127 parsing avoids duplicate symbol_lookup calls).
6128 * Changed handling of baseclasses (no longer use baseclasses field
6129 of struct type, use the first n_baseclasses fields instead).
6130 * Various minor changes/fixes, most C++-related.
6133 Cache the most previous match from find_pc_partial_function.
6134 (Save both low and high ends of matching function's pc range.)
6135 This speeds up the loop of infrun.c:wait_for_inferior quite
6136 a bit, and makes step/next commands much zippier.
6138 Added an enum->int cast (otherwise, some compilers barf).
6140 No longer set baseclass offset to 0, since multiple
6141 inheritance now mostly works.
6142 Added a number of casts, to shut up compiler warnings
6143 (after stabs where made enums, not ints).
6144 When discarding a symbol table (in symbol_file_command),
6145 must clear the cache introduced in blockframe.c.
6146 Don't convert $vtbl_ptr_type to vtbl any more.
6147 Get rid of TYPE_BASECLASEES and baseclass_vec (see also symtab.h).
6148 Mask off sign bit emitted by g++ for virtual table offset.
6149 Set voffset to -1 (not 1) for static member functions.
6151 Changed parsing/lexing of names to avoid doing symbol lookup twice
6152 (once when lexing to determine symbol class, once for real).
6153 Now only call symbol_lookup once. Fields of 'this' win especially big.
6155 Subpress printing addr twice in the case of 'x/s addr'.
6157 lookup_basetype_type is no longer used.
6158 Add find_methods as recursive helper function to decode_line_1.
6159 This allows multiple inheritance to work.
6160 Also, once one or more matches has been found, do not look in
6161 base-classes. (Baseclass methods would be overridden, anyway.)
6163 Removed baseclasses array in struct type.
6164 Instead of using baseclasses[i], use fields[i-1].
6165 Added virtual_field_bits[i] to indicate if the i'th baseclass is virtual.
6166 Changed sign convention of voffset (previous was inconsistent).
6168 Some macros (CALL_DUMMY and relatives) were missing. Put them back.
6170 Used to assume existence of vsprintf. Re-written to not need it
6171 if HAVE_VPRINTF is undefined.
6173 typecmp was too pessimistic. Made it less so.
6175 Don't print space after address.
6176 If vtable points to a misc symbol (with 0 offset), print it,
6177 since that indicates the actual class of the object.
6178 Changed ype_print_derivation_info to use new inheritance
6179 scheme (without baseclasses vector).
6181 In value_primitive_field, fixed some bugs left over from previous set of fixes.
6182 Also, changes needed because TYPE_BASECLASSES were removed.
6184 REGISTER_U_ADDR didn't work for PC. Rewrote to use an array.
6186 Tue Aug 21 20:08:54 1990 John Gilmore (gnu at cygint)
6189 If there is no path set, and the symbols don't indicate what directory
6190 a file was compiled in, look in the current directory. But either
6191 a path or a known compilation directory will prevent this.
6194 Three independent bug fixes:
6195 * Remove the #if 0 block that breaks some stuff.
6196 * SunOS 4.1 fixed the promoted-parameter-wrong-addr bug in Sun C;
6197 adapt gdb to either SunOS 4.0.* or 4.1.
6198 * MAX_OF_TYPE and MIN_OF_TYPE thinko. By tedg@sun, I think.
6201 Instantiate the class T when looking for methods in it. (Tiemann@sun)
6204 (type_print) Demangle the name being printed.
6205 (type_print_base) Handle botched demangling without coredump (tiemann).
6208 (check_stub_method): Document routine.
6209 (tiemann) fix bug for no-arg functions
6210 Avoid clobbering beyond end of malloc'd storage.
6211 Terminate the argument list properly.
6213 Sat Aug 18 01:29:59 1990 Per Bothner (bothner@cs.wisc.edu)
6215 * Changes merged by John Gilmore:
6218 In breakpoint_1, use new print_address_symbolic instead
6219 of find_pc_partial_function. (This forces use of assembler-level
6220 addresses, and avoids misleading non-mangled source-level names.)
6222 Generalize ansi argument such that -1 means skip arglist totally.
6223 Removed global variable print_ansi_qualifiers (which made
6224 code non-reentrant), in favor of extra explicit arguments
6225 to internal routines.
6227 Add new helper function print_address_symbolic.
6228 Use find_pc_misc_function instead of find_pc_partial_function
6229 (since we want assembler-level symbols here).
6231 Print unknown function as just "f (...)", not "f (...) (...)".
6232 Use new fputs_demangled explicitly.
6234 Fixed a typing violation (problem: value.h cannot be imported
6235 without renaming many variable in this file).
6236 lookup_symbol: If no matching misc_func, look for a C++-mangled name.
6237 decode_line_1: Moved forward some never-reached code.
6238 Made decode_line_2 skip function prologues correctly.
6240 fputs_filtered should not demangle by default.
6241 Add new fputs_demangled to demangle on demand..
6243 Change value_struct_elt to use value_primitive_field (using recursive
6244 utility function search_struct_field). This allows foo.bar to work
6245 for multiple inheritance (so far only for data fields).
6246 Change check_field in the same way (recursive helper function
6247 to support multiple inheritance).
6248 (Note: there are more of these problems that I haven't fixed.
6249 Any code that says TYPE_BASECLASS (t, 1) is probably wrong.)
6250 value_of_this: 'this' symbol name is now just "this", note "$this".
6252 Don't print static members.
6253 Avoid printing "members of <type>" if there are none.
6254 Simplified type_print_derivation_info by merging duplicate code.
6255 Remove useless blank lines in type_print_base (ptype command).
6257 Added declaration of new routine value_primitive_field.
6259 Added value_primitive_field which is generalized version of
6260 value_field that can handle multiple inheritance (non-zero offsets etc).
6261 Re-implemented value_field to call value_primitive_field.
6263 Fri Aug 17 23:33:44 1990 John Gilmore (gnu at cygint)
6265 * infcmd.c -- insert else to avoid 'delete env' coredump when you
6266 delete the whole environment. Karl Berry reported the bug.
6267 * source.c - fix openp to avoid //'s in filenames, which
6268 trigger an Emacs bug causing it to not be able to find files
6269 when running gdb in a window.
6270 * dbxread.c - zap the #if 0 that botches the add-file code.
6271 It seems to work a lot better without all the code commented out.
6273 Fri Jul 20 16:58:46 1990 John Gilmore (gnu at cygnus.com)
6275 * Merge Tiemann's and Ted Goldstein's changes, detailed below,
6278 Tue Jul 17 19:34:33 1990 Ted Goldstein (tedg at golem)
6280 * Makefile - added a ${CFLAGS} to a couple of entries,
6281 added remote-sa.sparc.c
6282 * added remote.sa-sparc.c, a modification of remote.c
6283 which conducts a dialog directly with the SparcStation prom.
6284 * breakpoint.c, infrun.c, sparcdep.c added
6285 remote_insert_breakpoint(), and remote_remove_breakpoint()
6286 to breakpoint.c instead of directly writing breakpoint instructions.
6287 * sparcdep.c on remote_debugging,there is no need
6288 to remove signle step breakpoint instructions.
6289 * main.c added "-epoch" flag and "int epoch_interface" to main.c
6291 * printcmd.c - epoch interface sends lisp expressions to open up
6292 epoch windows on inspection.
6293 * valprint.c - added arrayprint, and addressprint and made adding
6294 format controls easier
6295 * wait.h added a couple of undef's because we were getting
6296 complaints about WSTOPSIG and WTERMSIG begin redefined.
6299 Wed Jul 4 05:27:51 1990 Michael Tiemann (tiemann at masham)
6301 * symtab.c (decode_line_1): Add support for handling method stubs
6302 in the type information.
6304 Tue Jul 3 09:39:18 1990 Michael Tiemann (tiemann at masham)
6306 * values.c (baseclass_addr): Run loop from INDEX+1 to
6307 N_BASECLASSES; otherwise, we can still get into a loop.
6308 @@ This should be restructured to use a cleaner search strategy.
6310 Sun Jul 1 12:28:51 1990 Michael Tiemann (tiemann at masham)
6312 * dbxread.c (define_symbol,read_type): Grok GNU C++'s new
6313 abbreviation "Tt" for tags which have the same name as their
6316 Fri Jun 29 01:03:46 1990 Michael Tiemann (tiemann at masham)
6318 * symtab.c (list_symbols): add ability to set breakpoints on all
6319 the functions which match a particular regular expression.
6321 Tue Jun 26 04:26:29 1990 Michael Tiemann (tiemann at masham)
6323 * cplus-dem.c (cplus_demangle): New parameter ANSI says whether we
6324 should print ANSI qualifiers (such as `const' and `volatile').
6325 All callers changed to call with ANSI == 1, except from
6326 `check_method_stub', which uses old-style syntax.
6328 * symseg.h (struct fn_field): Remove unneccessary `args' field.
6329 * symtab.h (TYPE_FN_FIELD_ARGS): Redefined.
6331 * values.c (check_stub_method): New function.
6333 * cplus-dem.c (do_type): Handle "long long" (encoded as 'x').
6335 * dbxread.c (read_type): Handle new GNU C++ method type stubs.
6336 * valprint (type_print_base): Ditto.
6338 * symtab.c (gdb_mangle_typename): New function.
6340 Tue Jun 5 00:18:43 1990 Michael Tiemann (tiemann at gzilla)
6342 * breakpoint.c (catch_command): New function. Provides a
6343 mechanism to set breakpoints based on catch clauses.
6344 (disable_catch): Similar, but disables breakpoints on catch
6346 (delete_catch): Similar, but deleted breakpoints on catch clauses.
6348 Sun Jun 3 22:54:08 1990 Michael Tiemann (tiemann at gzilla)
6350 * blockframe.c (blockvector_for_pc): New function.
6351 * blockframe.c (block_for_pc): Changed to call
6352 `blockvector_for_pc' and get the block itself.
6354 * stack.c (catch_info): New function. Prints info about
6355 exceptions which can be caught in the current frame.
6356 * stack.c (print_frame_label_vars): New function. Similar to
6357 `print_frame_local_vars'.
6358 * stack.c (print_block_frame_labels): Prints out labels that are
6359 defined in this frame. These labels are exceptions that can be
6362 * dbxread.c: Updated to handle N_CATCH symtab types.
6364 Thu May 3 22:10:00 1990 Michael Tiemann (tiemann at teacake)
6366 * valprint.c (everywhere): TYPE_NAME (TYPE) no longer comes in the
6367 form "struct ..." for GNU C++. Don't flush any part of TYPE_NAME
6368 when printing the type.
6370 Wed May 2 22:43:04 1990 Michael Tiemann (tiemann at teacake)
6372 * valprint.c (val_print): Use `baseclass_addr' to access the
6373 baseclasses pointed to via the derived class object at VALADDR.
6375 * values.c (baseclass_addr): New function. Casts derived pointers
6376 to baseclass pointers taking virtual baseclasses and multiple
6377 inheritance into account.
6379 Sat May 5 12:39:18 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
6383 Fri May 4 12:12:55 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
6385 * breakpoint.c (watch_command, bpstat_stop_status): Deal with
6386 exp_valid_block field correctly.
6388 * infrun.c (wait_for_inferior): When checking "don't even think
6389 about breakpoints" if stop_signal == SIGTRAP && trap_expected,
6390 also check step_resume_breakpoint.
6391 Insert breakpoints and continue (not step) if
6392 step_resume_break_address != NULL, even if another_trap.
6393 If trap_expected and we enter sigtramp, then set up a
6395 If trap_expected is set when we hit the step_resume_break,
6397 When calling resume and trap_expected says tell resume to step
6398 (2 places), also check step_resume_break_address.
6400 * infrun.c (wait_for_inferior): Don't set
6401 prev_{pc,sp,func_{start,name}} before calling wait ().
6402 Do set them after exiting loop.
6403 Move their declarations outside functions.
6404 (start_inferior): Initialize them.
