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

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

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

309 * dbxread.c: Make more errors into complaints.
310 (push_subfile, pop_subfile): Move to buildsym.c.
311 (dbx_symfile_read, dbx_symfile_init, fill_symbuf, read_dbx_symtab,
312 start_psymtab, psymtab_to_symtab_1, read_ofile_symtab,
313 dbx_psymtab_to_symtab, ): Use bfd ops, don't use file descriptor.
314 Pass objfile. Change callers.
315 (fill_symbuf, SWAP_SYMBOL): Take bfd as arg.
316 (read_dbx_symtab): Just wipe out new symbols, not all, on error.
317 (end_psymtab): Blow away psymtab if empty.
318 (process_symbol_pair): Swallow into read_ofile_symtab.
319 (process_one_symbol): Use push_context and pop_context.
320 (virtual_context): Delete #if 0'd obsolete stuff.
322 * buildsym.c (end_symtab): Pass objfile.
323 (dbx_lookup_type): Handle null typevector.
324 (dbx_alloc_type): Check file number, not sym number, for -1.
325 (find_symbol_in_list): Add for xcoffread.
326 (start_symtab): Default typevector is empty. Keep reusing same
328 (end_symtab): Take objfile argument and pass it to
329 allocate_symtab. Don't make a symtab if no blocks or symbols.
330 Handle empty typevector.
331 (push_context): New function for context stack nesting.
332 (read_type): Mark FIXME where we need to reintroduce type smashing.
334 * buildsym.h (pop_context): Macro, paired with push_context.
335 (subfile_stack): Move here from dbxread.c.
337 * coffread.c (end_symtab, read_coff_symtab): Take and use objfile arg.
338 (read_coff_symtab): Cleanup by freeing objfile, not all symtabs.
340 * mipsread.c (read_mips_symtab, parse_partial_symbols, parse_fdr,
341 new_psymtab, new_symtab): Take and use objfile arg.
343 * dwarfread.c (scan_compilation_units, start_psymtab,
344 process_dies, end_symtab, dwarf_build_psymtabs,
345 read_lexical_block_scope, read_func_scope, read_file_scope): Take
346 and use objfile argument.
347 (psymtab_to_symtab_1, read_ofile_symtab): Don't take or use file
348 descriptor. Use BFD internal functions instead.
349 (end_symtab): Call global allocate_symtab.
351 * elfread.c, target.c: Minor changes to accommodate objfiles.
352 * symtab.h: partial_symbol_table has no symfile_name member now.
353 (fn_fieldlists voffset): avoid non-int bitfield.
354 (struct symtab): Add objfile * and objfile_chain * of symtabs.
355 (struct partial_symtab): Add objfile * and objfile_chain * of
356 psymtabs. Remove symfile_name.
358 * symmisc.c: Lose free_all_symtabs, free_all_psymtabs.
359 (printsyms_command): Rename from print_symtabs. Add selective
360 listing if 2nd argument given. Print objfile info.
361 (printpsyms_command): Rename from print_partial_symtabs. Ditto all.
362 (printobjfiles_command): New; prints objfiles lists, and checks
363 for consistency of symtab, psymtab, and objfile lists.
365 * symfile.h, symfile.c, symtab.h: Lint
367 Fri Nov 8 23:38:48 1991 John Gilmore (gnu at cygnus.com)
369 * command.c: Include param.h.
370 * defs.h (warning_setup, warning): Declare.

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

766 * dbxread.c (read_enum_type): Avoid Modula-2 kludge that breaks C
768 * i387-tdep.c (double_to_i387): Fix typo for double_to_ieee_extended.
769 * utils.c (_initialize_utils): If !ISATTY, don't paginate.
770 * configure.in, tconfig/decstation, xconfig/decstation: Rename
771 dec3100 to decstation.
773 Mon Oct 14 13:37:50 1991 Roland H. Pesch (pesch at cygnus.com)

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

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

914 * nindy-tdep.c (nindy_frame_chain_valid): Use lookup_misc_func.
915 (Reported by Mark Peek <mark@imagen.com>.)
917 * solib.c (solib_map_sections): Relocate all sections, even
918 though only the text section's size is tracked. Mark ld_text
919 for eventual elimination as we generalize to N sections.
921 * infrun.c (wait_for_inferior): Don't check if the PC is in a
922 call_dummy if we were stopped by a random signal that is being
923 passed to the program. This produced wierd results when calling
924 functions in the inferior and signals (e.g. SIGALRM) were in use.
926 Tue Sep 24 18:05:30 1991 John Gilmore (gnu at cygnus.com)
928 * infrun.c (IN_SIGTRAMP): Not parenthesized properly.
929 Bugfix from Paul Eggert <eggert@twinsun.com>.
930 * tm-ultra3.h (IN_SIGTRAMP): Ditto.
931 * valprint.c (print_floating): Print 9 digits for IEEE floats.
934 Mon Sep 23 15:50:07 1991 John Gilmore (gnu at cygnus.com)
936 * Makefile.in: Roll VERSION to 4.1.1.
937 * source.c (line_info): Peter Schauer fixes a bug I introduced in
940 Fri Sep 20 16:10:52 1991 John Gilmore (gnu at cygnus.com)
944 * Makefile.in (VERSION): Set to 4.1.
945 * language.c (set_language_command): Print useful help message,
946 and restore the language string after giving help.
947 * valprint.c (typedef_print): Print typedef in C or M2.
948 * symtab.c (list_symbols): Use it.
949 * main.c (main): Avoid any output before (gdb) prompt when -q.
950 * language.c (set_language_command): Handle errors by restoring
951 the language string to its current state (fix from A. Beers).
952 * doc/gdbint.texinfo: Roll in information from README. Rearrange
953 "how to install" and "how to print the doc" stuff so it drops
955 * configure.in: Rename rtpc CPU to romp to match config.sub.
956 * README, WHATS.NEW, TODO: Update for gdb-4.1.
958 Fri Sep 20 17:39:14 1991 Roland H. Pesch (pesch at cygnus.com)
960 * doc/gdb.texinfo: Updates from ChangeLog. set/show write,
961 autoloading shared libs, copyright etc on GDB startup, clean up $_
962 and $__ index refs, set/show listsize and related updates to list
963 cmd. New host/target configs.
965 Fri Sep 20 15:46:00 1991 Roland H. Pesch (pesch at cygnus.com)
967 * doc/Makefile: generate aux version-no file doc/gdbVN.m4
968 from main Makefile.in version definition
969 doc/gdb.texinfo: use version recorded in doc/gdbVN.m4 for current
971 Makefile.in (setup-to-dist): generate doc/gdbVN.m4
973 * doc/gdb.texinfo: merge new language-switching and lang-specific
976 Fri Sep 20 15:00:57 1991 Per Bothner (bothner at cygnus.com)
978 * mcheck.c: Add __ONEFILE kludge to allow compilation by non-ANSI
979 compilers (which may lack stddef.h).
981 Fri Sep 20 13:29:42 1991 John Gilmore (gnu at cygnus.com)
983 * dbxread.c (read_dbx_symtab, process_one_symbol): N_FN and
984 N_WARNING are the same except for the N_EXT bit, so just use their
985 values alone, rather than OR-ing them with N_EXT.
987 Fri Sep 20 12:27:55 1991 Stu Grossman (grossman at cygnus.com)
989 * mipsread.c (parse_lines): Deal with negative extended line
992 * c-exp.y, m2-exp.y: #define yyerrflag and yynerrs to avoid
993 global symbol conflicts.
995 Fri Sep 20 02:28:15 1991 John Gilmore (gnu at cygnus.com)
997 * .gdbinit: Move 'set complaints' to top, so it runs even in
998 case we aren't debugging GDB.
999 * language.c (_initialize_language): Fix type check and range
1000 check documentation strings.
1001 * utils.c (!HAVE_VPRINTF): Define vfprintf as a function, so
1002 language.c can use it. (Though language.c should really not be
1003 handling warnings/errors the way it does, FIXME.)
1004 * symtab.c (lookup_primitive_type): const lint.
1006 Bugfix from Peter Schauer:
1007 * source.c (lines_to_list): Make signed, to avoid comparison
1008 going unsigned and complaining that -3 is too high for 21 lines.
1009 * stack.c (lines_to_list): Ditto.
1011 Thu Sep 19 23:33:41 1991 John Gilmore (gnu at cygnus.com)
1013 * Makefile.in (HFILES): Add minimon.h.
1014 (VERSION): Roll version number to 4.0.95.
1015 (gdb.tar.Z, make-proto-gdb.dir, setup-to-dist, gdb-XXX.tar.Z):
1016 New rules for building distributions. Normal distribution
1017 is built by doing `make -f Makefile.in gdb.tar.Z' in the directory
1018 one level up from here; it calls make-proto-gdb.dir to build a
1019 directory `proto-gdb' which is an image of the release. The old
1020 `gdb.tar.Z' rule still works too.
1021 * config.sub, configure: Roll in latest from ..
1023 Thu Sep 19 17:41:24 1991 Roland H. Pesch (pesch at cygnus.com)
1025 * doc/gdbint.texinfo: Reorder contents; reorganize new-host,
1026 new-target, and new-config chapters; fix minor typos; come closer
1027 to usual GNU markup conventions for @file @samp @code @var.
1029 Thu Sep 19 17:04:12 1991 Per Bothner (bothner at cygnus.com)
1031 Patches from Peter Schauer <pes@regent.e-technik.tu-muenchen.de>:
1032 * mipsread.c (parse_partial_symbols): Enter the name of all
1033 structs/unions... into the psymtab so we can access them if the
1034 symtab is not read in.
1035 * mips-tdep.c: Remove some unneeded #includes.
1036 * xconfig/dec3100: Add HAVE_STRSTR.
1038 Thu Sep 19 15:14:23 1991 John Gilmore (gnu at cygnus.com)
1040 * Makefile.in: Circumvent Sun Make bug on *-exp.tab.o.
1041 * c-exp.y, m2-exp.y: Lint.
1042 * m2-exp.y: Avoid using yytname[] which is a Bison-ism.
1043 * valprint.c (val_print_fields): Check for stub type.
1044 * mipsread.c (_initialize_mipsread): Avoid using
1045 builtin_type_void at initialize time.
1046 (mipscoff_symfile_read): use it now.
1048 Wed Sep 18 15:55:51 1991 John Gilmore (gnu at cygnus.com)
1050 Merge multiple-language support, and partial Modula-2 support,
1051 from Andrew Beers <beers@cs.buffalo.edu>.
1053 * i387-tdep.c: New file, consolidates most 80387 support,
1054 and eliminates host dependency on double<->extended conversions.
1055 * i386-xdep.c, symm-xdep.c: Remove most 387 support.

1073 (process_coff_symbol): #if 0'd for functions and params as above.
1074 (read_enum_type): Recognize Modula-2 BOOLEAN.
1075 * symtab.c (add_param_to_type): #if 0'd function to add a

1113 * expression.h (enum exp_opcode): Add Modula-2 specific opcodes.
1114 * expprint.c: Look up expression opcodes in language-specific

1147 Tue Sep 17 08:37:41 1991 John Gilmore (gnu at cygint.cygnus.com)
1149 Add Andrew Beers' changes for Modula-2 support. His ChangeLog
1150 entries are enclosed herein. Not all of these changes
1151 have been merged into the master GDB sources -- check the
1152 ChangeLog above here for the merge log.
1154 Mon Jun 3 17:05:45 EDT 1991
1156 m2-exp.y Created. Tested outside of GDB for a few days. Proper
1157 operators were added, C specific operators and tokens
1158 removed. yylex() revamped to some extent. Still things
1159 missing from the grammar, such as sets.
1160 Tested for two weeks in GDB v3.5.
1162 Tue Jun 11 17:23:48 EDT 1991
1164 m2-exp.y Added boolean constants TRUE and FALSE to the grammar
1165 so they are built-in. Sort of a hack.
1167 Fri Jun 14 12:53:51 EDT 1991
1169 m2-exp.y Added range checking for numeric constants. Any numeric
1170 constant is assumed to be of builtin type INTEGER unless:
1171 (1) it is octal or hexadecimal, in which case it is a
1172 CARDINAL; (2) it is too big to fit into an INTEGER, in
1173 which case it is a CARDINAL.
1174 eval.c Added simple range checking for +, -, and * on integers.
1175 Doesn't work very well for *, since 6 * 1,000,000,000 =
1176 1,705,032,704, which fails the simple test of result >=
1177 first_operand, no matter in what order the operands are.
1179 Tue Jun 18 14:11:30 EDT 1991
1181 Broke the parser into parts, one containing the C grammar and the other
1182 containing code to be shared by all of the grammars.
1184 The following files no longer exist:
1189 The following files were added:
1191 c-exp.y (The C grammar)
1192 m2-exp.y (The Modula-2 grammar)
1193 parser-code.c (Code that is shared by the above grammar)
1197 Makefile.dist Changed to reflect the above dependencies. NOTE: It is
1198 now necessary to use the Bison compiler compiler, since it
1199 will generate function/variable prefixes other than yy.
1201 Tue Jun 18 16:47:49 EDT 1991
1203 symtab.[ch] Added the external variable working_lang, than holds the
1204 value of the current working language.
1205 Added the ennumerated type language_mode, with the values
1206 language_auto and language_manual, the former meaning that
1207 GDB sets working_lang as needed, and the latter meaning
1208 that the value of working_lang is totally under user
1210 symtab.[ch] Added the Modula-2 pervasive types INTEGER, CARDINAL,
1211 REAL, BOOLEAN and CHAR. Also added the type codes
1212 TYPE_CODE_BOOL and TYPE_CODE_CHAR.
1213 utils.c Added set_language_command and show_language_command to
1214 implement the GDB support commands "set language" and
1216 expression.h A number of identifiers were added to the type exp_opcode
1217 to facilitate Modula-2 builtin functions, integer
1218 division, and array indexing.
1220 Wed Jun 19 13:25:58 EDT 1991
1222 language.h Added the macro STRICT_TYPE, which evaluates to non-zero
1223 if the language specified by working_lang requires the use
1224 of strict typing of expressions. Eventually, even this
1225 will be able to be changed by the user.
1226 Added the macro RANGE_CHECK, which evaluates to non-zero
1227 if the language specified by working_lang requires the
1228 checking of a value against the domain of its type.
1229 Eventually, even this will be able to be changed by the
1231 language.[ch] Predicates involving types (simple_type, ordered_type,
1232 same_type, integral_type, numeric_type, character_type,
1233 boolean_type, float_type) are added. These predicates are
1234 based on the current value of working_lang, and are handy
1237 Wed Jun 19 15:39:34 EDT 1991
1239 eval.c Added the function type_array_rank which computes the rank
1241 valarith.c Added the funtion value_bool, which when given a integer
1242 value.h value (ie. struct value *) as an argument, it returns a
1243 boolean value (ie. struct value *) true if that integer
1244 is non-zero, and a boolean value false otherwise.
1245 valprint.c Added cases for TYPE_CODE_BOOL, so Modula-2 BOOLEAN values
1246 will print out properly.
1248 Wed Jun 19 16:36:34 EDT 1991
1250 valops.c Added the function value_capitalize, which returns it
1251 value.h argument capitalized if its argument is a lowercase
1252 letter, or the argument unchanged if its argument is not a
1254 valarith.c Added the function range_check_p, which returns non-zero
1255 value.h if its value argument is between the integral bounds upper
1257 Added the function range_check_enum_p, which makes sure
1258 that its value argument is a valid member of the domain of
1260 Added the function range_check_range_p, which makes sure
1261 its value argument lies between the upper and lower bounds
1262 of its type argument, which must be a ranged type.
1263 Added the function check_array_index, which range and type
1264 checks an index of an array.
1265 Added the function value_multi_subscript, which computes
1266 array[idx1,idx2...idxN], given a value array and an array
1267 of values representing indicies.
1268 values.c Changed value_from_long to work with TYPE_CODE_CHAR and
1269 unpack_long to work with TYPE_CODE_BOOL and
1272 Wed Jun 19 18:04:08 EDT 1991
1274 symtab.c Stored pervasive types in a structure and make
1275 lookup_pervasive_type() a lookup function that was based
1276 on working_lang. If lookup_pervasive_type() returned
1277 non-zero, then that value was returned (a fix, since
1278 before it simply wouldn't return the pervasive type.)
1279 language.h Added the macro CAST_IS_CONVERSION, which evaluates to
1280 non-zero if the language specified by working_lang means
1281 "conversion" when it says "cast".
1282 valops.c Added the function value_real_cast(), which performs a
1283 value.h *cast*, not a *conversion*, which is what value_cast()
1284 does when it can. In particular,
1285 value_cast(<float_type>,4) = 4.0, while
1286 value_real_cast(<float_type>,4) = some mess.
1287 eval.c Modula-2 builtin functions implemented: ABS, CAP, CHR,
1288 parser-code.c FLOAT, HIGH, MAX, MIN, ODD, ORD, TRUNC, and VAL.
1289 expression.h Added macros MAX_OF_TYPE and MIN_OF_TYPE to work with MAX
1290 and MIN on integral types. *NOTE*: These are currently
1291 hardcoded to work only if there are 8 bits per storage
1293 eval.c Made logical functions call value_bool to return a
1294 properly typed boolean value, based on working_lang.
1296 Thu Jun 20 11:55:27 EDT 1991
1298 valprint.c Types now print out in a Modula-2 fashion. This works for
1299 the cases when the type is printed out step-by-step, that
1300 is, it doesn't work when the name of a structured type
1301 (which includes the keyword "struct", etc.) is simply
1303 FIXME: Perhaps this is bad. Parts of it seem to kludgey,
1304 since type specifications in C and Modula-2 are very
1305 different. The C printing of a type is very recursive,
1306 whereas in Modula-2 it is generally very simple. C has
1307 type prefixes and suffixes, which have no real analogue in
1308 Modula-2. Maybe type_print() should call a language
1309 specific type printer. This is also advantageous if we
1310 compile GDB to exclude some of the languages. We'll just
1311 leave those functions out.
1313 Thu Jun 20 16:57:10 EDT 1991
1315 dbxread.c When reading the complete symbol table in (via
1316 psymtab_to_symtab()), the number and types of function
1317 arguments are added to a function type. define_symbol()
1318 calls add_param_to_type() to accomplish this.
1319 Assumption: when we come across a function definition
1320 (N_FUN symbol with an 'f' or 'F' in the name), its
1321 arguments will appear before another function definition.
1322 When a function is found, a pointer to its type is placed
1323 in the global in_function_type. Changes that
1324 add_param_to_type() makes are to this global.
1325 valprint.c The type of a function now includes (for Modula-2) the
1326 types of its parameters.
1327 eval.c Type checking and a check for the proper number of
1328 arguments is now done for function calls. Not sure of the
1329 impact this has on C++ member function yet.
1331 Thu Jun 20 19:58:48 EDT 1991
1333 valprint.c Rewrote the type printer. Broke it into two language
1334 specific parts, adding the functions type_print_m2() and
1336 An unfortunate consequence is this: if you debugging a C
1337 program in Modula-2 mode (why?), info types does not work
1338 well with regular expressions, since the types are printed
1339 out in Modula-2 terminology, but stored in C terminology.
1340 language.[ch] Added the functions new_type_last(), type_keyword(), and
1341 type_sep() to aid in the printing of typedefs.
1342 symtab.c Made the printing of typedefs as language independent as
1343 possible through calls to new_type_last(), type_keyword(),
1346 Fri Jun 21 11:50:26 EDT 1991
1348 dbxread.c Check all incoming ennumerated types. If it looks like
1349 Modula-2's BOOLEAN type, then change the type_code of the
1350 type to TYPE_CODE_BOOL so we can process it as a boolean
1352 valprint.c Replaced some of the 0x%x with calls to sprintf and
1353 hexformat() in val_print().
1354 language.[ch] Added the function hex_to_string(), which converts its
1355 integral argument to a hexadecimal number (format is
1356 language based) and returns the result as a string.
1358 Mon Jun 24 12:25:07 EDT 1991
1360 valprint.c Some functions call type_print_1() directly, instead of
1361 value.h using type_print(), so they can specify where (column) to
1362 print things. Since type_print() takes care of language
1363 dependence, that needs to be called first. Added a
1364 parameter depth to type_print() (so it is now like
1365 type_print_1). Changed type_print to type_print_at, and
1366 made type_print a macro that passes a depth argument of
1368 symmisc.c Changed all calls to type_print_1 to calls to
1370 Makefile.dist Made it possible to build GDB for a specific set of
1371 depend languages. Do this by passing a definition for the macro
1372 LANGS to make. LANGS should be a string containing a
1373 space-separated list of language names (ie. LANGS="c m2").
1374 The default is to build all languages. Note that grammar
1375 files must follow the naming convention of <lang>-exp.y.
1376 gdb.lang This holds the current value of the LANGS macro. It is
1377 examined every time make is called, and is updated if
1379 eval.c Added #ifdef _LANG_<lang> to these files.
1380 expread.c Still need to add them to dbxread.c and coffread.c.
1388 Mon Jun 24 16:33:11 EDT 1991
1390 language.[ch] Added the functions hexformat_pre() and
1391 hex_to_string_pre(), which take a prefix argument to
1392 include in the format string. Thus, hexformat_pre("08") will
1393 return "0x08x" (if the working language is language_c).
1394 Made hexformat() and hex_to_string() calls to the above
1395 with "" as the prefix argument.
1397 am29k-pinsn.c, arm-pinsn.c, breakpoint.c, convex-tdep.c, exec.c, core.c,
1398 dbxread.c, i386-pinsn.c, i386-stub.c, i386-xdep.c, i960-pinsn.c,
1399 infcmd.c, inflow.c, m68k-pinsn.c, m68k-stub.c, m88k-pinsn.c,
1400 mips-pinsn.c, mips-tdep.c, ns32k-pinsn.c, printcmd.c, pyr-pinsn.c,
1401 pyr-tdep.c, pyr-xdep.c, remote-vx.c, remote.c, solib.c, source.c,
1402 stack.c, sun386-xdep.c, symfile.c, symm-xdep.c, symmisc.c, tahoe-pinsn.c,
1403 valprint.c, vax-pinsn.c
1405 Changed all occurences of 0x%[0-9]*l*x in printf format strings to
1406 calls to hexformat() and hex_to_string(). Format strings without
1407 the leading "0x" were ignored.
1409 depend Updated to take the above into account.
1412 Tue Jun 25 15:27:18 EDT 1991
1414 symtab.h Added the types range_mode_t, range_check_t, type_mode_t,
1415 and type_check_t to keep track of the current state of
1416 range and type checking.
1417 main.c Added the variables range_mode, range_check, type_mode,
1418 and type_check to record the current state of range and
1419 type checking. Added initialization code to main().
1420 language.h Changed the macros STRICT_TYPE and RANGE_CHECK to examine
1421 the above variables.
1424 Tue Jun 25 17:57:08 EDT 1991
1426 dbxread.c process_one_symbol() updates the variable (enum language)
1427 source_lang based on the extension of the filename
1428 contained in the N_SO sybmol that started this symtab.
1429 When end_symtab() is called, the value of source_lang is
1430 put into the language field.
1431 stack.c select_frame() sets working_lang (and possibly type_check
1432 and range_check) to the language field of the symtab
1433 associated with the frame that is selected if working_mode
1434 is language_auto. If working_mode is language_manual, a
1435 warning is printed and working_lang is not set.
1436 language.c Added the function set_type_range(), which sets the value of
1437 type_check and range_check (if their modes call for
1438 automatic setting) based on the current value of
1439 working_lang. A non-zero argument will cause the current
1440 settings to be output.
1443 Wed Jun 26 14:51:40 EDT 1991
1445 eval.c Added range checks on assignment.
1446 m2-exp.y Added the grammar for sets to the language. Currently,
1447 these do not do anything except print an error message.
1449 Wed Jun 26 17:01:04 EDT 1991
1451 m2-exp.y Added the ability for parse_number() to parse negative
1452 numbers. A global flag is set upon encountering a unary
1453 minus. This was done to make, for example, 1 parse as a
1454 CARDINAL, and not as an integer, per Wirth's examples in
1455 Programming in Modula-2 ed.4.
1456 valprint.c Added support for "set radix 2" by then setting
1457 output_format to 't'.
1458 eval.c Implemented range checking on subrange types. Added calls
1459 to range_check_range_p for BINOP_ASSIGN and BINOP_VAL.
1460 Implemented MIN and MAX for ennumerated types. The
1461 minimum value of an ennumerated type is defined by Wirth
1462 as the first identifier, and the maximum as the last.
1463 m2-exp.y Made octal numbers ending with "B" be characters and those
1464 ending with "C" be numbers, per Wirth's book. (p. 34)
1466 Thu Jun 27 14:11:52 EDT 1991
1468 stack.c select_frame() now only sets working_lang, it does not
1469 notify the user. If working_mode is language_manual, then
1470 a warning is issued once.
1471 main.c At the end of each call to execute_command(), working_lang
1472 is checked against the local static (enum language)
1473 current. If they differ and working_mode is
1474 language_auto, the new settings of language, type and
1475 range checking are printed out.
1476 stack.c Modified frame_info() to include the language of the
1477 current frame in the output of "info frame".
1478 language.[ch] Added the function language_str() which returns the name
1479 of the current language.
1481 Fri Jun 28 15:33:14 EDT 1991
1483 m2-exp.y Added the built-in procedures INC, INCL, DEC, and DECL to
1484 the language. INCL and DECL currently cause an error,
1485 since sets are not implemented yet. INC and DEC are
1486 implemented as PREINCREMENT/PREDECREMENT with one
1487 argument, and as ASSIGN_MODIFY with two arguments.
1488 eval.c Added type checking to the above cases.
1489 value.h Added not_lval_constant to the lval_type ennumerated type.
1490 not_lval_constant means that the value is a constant
1491 value; that is 3 or 'a' or TRUE, not as in a constant
1492 identifier. This is used to help coerce numbers such as 3
1493 to either signed or unsigned numbers.
1494 valops.c Added the function value_coerce_constants() which coerces
1495 constant integers as following: if one is a constant and
1496 the other is not, the constant's type is set to the type
1497 of the other argument. If both are constants and one is
1498 signed, the other is converted to a signed constant.
1500 Sat Jun 29 17:26:29 EDT 1991
1502 valarith.c Added a better range checker. It now checks range
1503 (successfully) on integral operations [+-] (signed and
1504 unsigned) for any C sized type. Still does not work well
1505 for multiplication.)
1506 int_in_size() returns an integer that is coerced to fit into
1507 specified number of bytes.
1509 Mon Jul 1 13:04:14 EDT 1991
1511 language.[ch] Added the function binop_result_type(), which returns the
1512 builtin (struct type *) type that would be the result of a
1513 binop on the two values V1 and V2.
1515 Wed Jul 3 19:22:53 EDT 1991
1517 source.c Extended source_info() to include the source language in
1518 the output from "info source".
1520 Fri Jul 5 13:48:52 EDT 1991
1522 utils.c Moved the support functions for the GDB set/show commands
1523 dealing with language into language.c.
1524 language.c Added the function language_info(), which displays info
1525 about the current working language, type and range check
1526 settings. Called via the GDB command "info language".
1527 Added an initialization routine _initialize_language(),
1528 that sets defaults for the language, type and range
1529 variables and sets up the new GDB commands.
1530 main.c Language setup moved to language.c.
1533 Mon Jul 8 10:10:22 EDT 1991
1535 valarith.c Debugged the range checker for arithmetic. Still does not
1536 work for multiplication very well.
1538 Mon Jul 8 12:40:37 EDT 1991
1540 language.[ch] Added the function value_true() which returns non-zero if
1541 its argument represents a boolean true value.
1542 breakpoint.c Changed breakpoint_cond_eval() to call value_true() to
1543 check the truth of an expression.
1545 Thu Jul 11 12:51:34 EDT 1991
1547 language.[ch] Added the predicate structured_type(), which returns
1548 non-zero if the argument is a structured type.
1549 Added the predicate pointer_type(), which returns non-zero
1550 if the argument is a pointer type.
1551 eval.c Added the ability to do addition and substraction on
1552 pointers and integers. This case simply bypasses the
1555 Thu Jul 11 14:41:42 EDT 1991
1558 Added the symbol N_DEFD (0x4a) which is a definition
1559 module dependency that is used by the GNU Modula-2
1560 compiler and the linker. It is not important to GDB,
1561 except that [dbx|coff|mips]read.c should ignore these
1564 Fri Jul 12 16:07:00 EDT 1991
1566 valprint.c Changed the TYPE_LENGTH(type) >= 0 to TYPE_LENGTH(type) >
1567 0 in val_print(). Also added statements to the else part
1568 to coerce type (argument to val_print) to a pointer type
1569 if it is an "array of unspecified length".
1570 valops.c Added the function value_m2_string(), which returns a
1571 (value) value which is a constant string, whose type is
1572 (ARRAY [0..n] OF CHAR). The length field of the type
1573 structure is set to zero, so it will be interpreted as an
1574 "array of unspecified length".
1575 stack.c Moved the language/frame mismatch check to
1576 main.c:execute_command().
1577 main.c The working language is recorded each time
1578 execute_command() is executed. If working lang has
1579 changed during its execution, then the new
1580 language/type/range info is printed out for the user. If
1581 the working language does not match the language of the
1582 frame, a warning is issued.
1584 Sat Jul 13 16:16:39 EDT 1991
1586 eval.c Moved all the type-checking stuff for operators to
1587 language.[ch] language.c. This is so we can keep language-specific
1588 stuff (like for what type operators are defined) in
1590 language.[ch] Added the function binop_type_check(), which checks to see
1591 if its two (value) arguments are type-compatible with its
1592 opcode argument. The opcode should represent an operation
1593 involving an operator. Also added the macro function
1594 unop_type_check, which calls binop_type_check with a
1595 NULL second argument.
1596 expprint.c Added Modula-2 operators to the op_print_tab, so info
1597 expression.h break works correctly. Also added "op_string", which
1598 returns the string corresponding to the (enum exp_opcode)
1599 opcode that is its argument.
1602 Sat Jul 13 18:26:18 EDT 1991
1604 coffread.c Added code to record the type of function arguments with
1605 each paricular function. Code is very similar to that
1607 dbxread.c Moved add_param_to_type() to symtab.c
1608 symtab.[ch] Added function add_param_to_type() from dbxread.c
1610 *** NOTE: The above additions have not been tested.
1612 Mon Jul 15 12:50:47 EDT 1991
1614 langauge.[ch] Added the functions type_error and range_error, which work
1615 like error() except if the type/range mode is set to
1616 *_mode_warn, then they do not do a return_to_top_level(),
1617 but merely print a warning.
1618 Also changed [set|show]_[type|range]_command() to support
1619 the new "warn" feature.
1621 Thu Jul 18 17:50:54 EDT 1991
1623 mipsread.c Added code to record the type of function arguments with
1624 each particular function. Code is very similar to that
1627 *** NOTE: The above additions have not been tested.
1629 Fri Jul 19 11:19:10 EDT 1991
1631 defs.h Added macros MAX_OF_SIZE, MIN_OF_SIZE, UMAX_OF_SIZE, and
1632 UMIN_OF_SIZE, which when given a size of a numeric type,
1633 return the maximum and minimum value it can hold. UMAX...
1634 and UMIN... return the result for unsigned types.
1635 symtab.h Added the macros MAX_OF_TYPE and MIN_OF_TYPE to operate on
1636 struct types. They call above macros.
1637 dbxread.c Renamed the MAX and MIN_OF_TYPE macros to ..._OF_CTYPE to
1638 avoid a name conlict with the above.
1639 c-exp.y Added range checking on numeric constants in
1640 parse_number() for completeness.
1641 valarith.c Made binop_user_defined_p() and unop_user_defined_p()
1642 return 0 if working_lang is not language_c.
1644 Thu Aug 8 14:17:22 EDT 1991
1648 breakpoint.c Documentation strings of some commands changed to
1649 eliminate the references to the C language where
1652 Tue Aug 13 15:48:03 EDT 1991
1654 m2-exp.y Added qualified identifiers to the grammar. The semantics
1655 are slightly different from those of the GDB operator ::
1657 m2-exp.y Added a rule to each grammar of the form: start ::= exp |
1658 type_exp, where type_exp is any valid type expression.
1660 eval.c Added the opcode OP_TYPE, and an error case in eval.c.
1661 printcmd.c Modified ptype_command() so it actually parses the input
1662 (necessary for type expressions with scope qualifiers).
1663 Added the function ptype_eval() which expects an
1664 expression composed of one OP_TYPE element.
1665 *.[ch] Replaced all occurences of parse_c_expression with
1667 *.[ch] Replaced all occurences of parse_c_1 with parse_exp_1
1669 [End of ChangeLog entries from Andrew Beers for Modula-2 support.]
1671 Mon Sep 16 17:19:46 1991 John Gilmore (gnu at cygnus.com)
1673 Small fixes from Peter Schauer:
1675 * infrun.c (child_attach): Lint.
1676 * solib.c (find_solib): Handle shared libs version 2.
1678 Small fixes from David Wood:
1680 * xm-ultra3.h (SYS_SIGLIST_MISSING): Typo.
1684 * remote-vx.c: Move <stdio.h> to top, for FILE. Fix from
1685 John S <basrai%kanga.dnet@c3po.sm-alc.af.mil>.
1687 * utils.c (wrap_here): Avoid wrap action of fputs_filtered if
1688 chars_per_line is at maximum (user typed `set width 0'). Fix
1689 from Andreas Schwab <schwab@ls5.informatik.uni-dortmund.de>.
1691 Tue Sep 17 17:31:04 1991 Stu Grossman (grossman at cygnus.com)
1693 * coredep.c: include ptrace.h where necessary.
1694 * mipsread.c(parse_lines): fix unsigned char problem that was
1695 messing up line numbers on SGI's and possibly other MIPS based
1697 * infrun.c (child_create_inferior): use better test to check
1698 return val from setpgrp().
1699 * tm-irix3.h, xm-irix3.h, tconfig/irix3, xconfig/irix3: add these
1700 for sgi/irix support.
1702 Wed Sep 18 04:33:31 1991 Per Bothner (bothner at cygnus.com)
1704 * mipsread.c (parse_symbol): Put non-static procedures
1705 in the global block.
1707 Fri Sep 13 00:14:52 1991 John Gilmore (gnu at cygnus.com)
1709 Patch together `text_start' and `text_end' for 29K port.
1711 * exec.c (exec_command): If NEED_TEXT_START_END, define the
1712 variables and set them based on the exec file.
1713 * am29k-tdep.c: declare text_start.
1714 * valops.c (call_function_by_hand): declare text_end.
1716 * inferior.h: Eliminate CANNOT_EXECUTE_STACK in favor of
1717 defining CALL_DUMMY_LOCATION as BEFORE_TEXT_END. This is
1718 because machines that do this will also have to know to
1719 set NEED_TEXT_START_END. Besides, it was a redundant way to
1721 * tm-29k.h, tm-convex.h, tm-np1.h: Eliminate
1722 CANNOT_EXECUTE_STACK, define CALL_DUMMY_LOCATION and
1723 NEED_TEXT_START_END.
1725 Thu Sep 12 00:22:24 1991 John Gilmore (gnu at cygint.cygnus.com)
1727 AMD 29000 changes from David Wood <wood@david.ultra.nyu.edu>:
1729 * Makefile.in (CLIBS): Put XM_CLIBS and TM_CLIBS at end.
1730 Pass MUNCH_DEFINE to munch whenever we run it.
1731 * am29k-pinsn.c (print_insn): Handle NOP specially. Avoid %#x
1732 format string; use 0x%x instead.
1733 * am29k-tdep.c: Use DUMMY_SAVE_GREGS and RETURN_REGNUM.
1734 * ultra-xdep.c, xm-ultra.h: New files for Ultracomputer host system.
1735 * xm-rtbsd.h: New host support for RT/PC running BSD Unix.
1736 * inflow.c: Handle `short' process group IDs.
1737 * infptrace.c (fetch_register): Support CANNOT_FETCH_REGISTER,
1738 and check for ptrace errors.
1739 * coffread.c (SDB_REG_TO_REGNUM): Define if not already.
1740 (coff_symfile_init): Initialize text_bfd_scnum.
1741 (read_coff_symtab): Use it to find the text [and absolute?] sections.
1742 * ../config.sub: Add vendor nyu and os "sym[1-9]*".
1743 * configure.in: Add hosts rtpc-*-* and a29k-*-*.
1744 Merge target arm case with other "easy" cases. Add target
1745 cases a29k-*-none (rehack of am29k), a29k-*-kern (remote to
1746 Ultracomputer kernel), and a29k-*-sym1 (ultracomputer OS's user
1748 * minimon.h, remote-adapt.c, remote-mm.c: Add.
1749 * munch: Cope with RT/PC putting fns in data segment.
1750 Restore ability to override `nm' by specifying MUNCH_NM.
1751 * xconfig/rtbsd, xconfig/ultra3: New host systems.
1752 * tconfig/a29k: Rename from tconfig/am29k. Add remote-mm
1753 and remote-adapt. Remove encapsulated coff #define's (the
1754 support should go in BFD, and gdb shouldn't know or care).
1755 * tconfig/a29k-kern: Same, but for remote kernel debugging.
1756 * tconfig/ultra3: For debugging user processes on Ultra3/Sym1.
1757 * tm-29k.h: Update BADMAG (though it should go away).
1758 Allow the register definitions to be overridden in another
1759 tm-file. Fix SR_REGNUM. Add a mess of _REGNUM's. Separate
1760 RETURN_REGNUM from GR96_REGNUM and DUMMY_SAVE_GREGS from
1761 DUMMY_SAVE_GR96, for handling kernel calling conventions
1762 that use GR64+ rather than GR96+.
1763 * tm-ultra3.h: New file, for use on Ultra3 Unix as well as for
1764 remote debugging of Ultra3 kernel. Includes tm-29k.h and
1765 overrides various things.
1767 * remote-mm.c (mm_attach, mm_wait): Handle attach like
1768 child_attach does, making a clean stop in the newly attached
1770 * remote-eb.c: Lint.
1772 * coffread.c: Make coffread independent of any particular
1773 variant of COFF. Avoid #include-ing any particular one except
1774 internalcoff.h. BFD now passes key values for symbol reading
1775 as part of its coff_data structure (LINESZ, SYMESZ, AUXESZ,
1776 and the symbol masks and shifts); use them.
1777 Remove obsolete end_of_text_addr.
1779 * exec.c: Remove unused include files.
1781 Wed Sep 11 19:38:44 1991 John Gilmore (gnu at cygint.cygnus.com)
1783 * Makefile.in (documentation targets): Pass $(M4).
1784 Bugfix from eggert@twinsun.com (Paul Eggert).
1786 * stack.c (down_silently_command): Check for stack existence.
1788 Tue Sep 10 23:08:29 1991 John Gilmore (gnu at cygint.cygnus.com)
1790 * Makefile.in (VERSION): Update to 4.0.3.
1792 Tue Sep 10 09:19:29 1991 John Gilmore (gnu at cygint.cygnus.com)
1794 * core.c (core_file_command): Print frame at coredump with
1795 its level number, by calling print_stack_frame.
1796 * frame.h: Add selected_frame_level, print_stack_frame.
1797 * frame.h, stack.c: Remove print_sel_frame, print_selected_frame.
1798 * convex-tdep.c, convex-xdep.c, infcmd.c, inflow.c, infrun.c:
1799 Change print_sel_frame and print_selected_frame callers to
1802 * dbxread.c (read_ofile_symtab): Avoid empty else clause.
1803 * symfile.c (free_named_symtabs): Ditto.
1804 * main.c (main): wrap_here needs an arg.
1805 * solib.c (find_solib): Avoid memory access if _DYNAMIC is zero.
1806 (solib_add): Avoid noise.
1807 (solib_create_inferior_hook): Lint.
1808 (sharedlibrary_command): Move dont_repeat to here.
1809 * utils.c (error): Call wrap_here to force buffered output.
1811 Small patches from Peter Schauer:
1813 * coffread.c (start_symtab): Free any existing line_vector before
1815 (read_coff_symtab): Ditto for type_vector.
1817 * source.c (lines_to_list): New variable, replacing function.
1818 (all uses): Use as variable.
1819 (_initialize_source): Add 'set listsize' and 'show listsize'.
1820 * utils.c (lines_to_list): Remove function.
1821 * stack.c (print_frame_info): Use as variable.
1822 * defs.h (lines_to_list): Remove declaration.
1824 Mon Sep 9 13:45:57 1991 John Gilmore (gnu at cygint.cygnus.com)
1826 * breakpoint.c (insert_breakpoints): Restore warning about
1827 the program might be running in another process, but only for
1828 systems with this brain death (#ifdef ONE_PROCESS_WRITETEXT).
1829 * xm-hp300bsd.h, xm-mips.h, xm-vax.h: Define it.
1831 * utils.c (error): if error_pre_print is set, print the string
1833 * main.c (main, print_gnu_advertisement, print_gdb_version):
1834 Reformat legalese so it always prints, but acts as an "I'm here"
1835 message while symbols are being read. If any errors occur,
1836 print a few newlines to set off the message and start it at the
1837 left margin. Remove mention of "help" command, and don't yak
1838 about symbol reading.
1839 (catch_errors): Error string is now printed first in case of
1841 * command.c (undef_cmd_error, lookup_cmd): On undefined command,
1842 suggest the "help" command.
1844 * Makefile.in (VERSION): Set to 4.0.2.
1846 Thu Sep 5 23:49:48 1991 John Gilmore (gnu at cygint.cygnus.com)
1848 * .gdbinit: Remove useless "rr" command. Set complaints
1849 to 1 for people debugging gdb.
1851 * breakpoint.c, remote-vx.c: Reword strings printed by
1852 catch_errors callers.
1854 Wed Sep 4 11:07:50 1991 John Gilmore (gnu at cygint.cygnus.com)
1856 * WHATS.NEW: "history write -> history save". Doc "write on/off".
1857 (Fix from kenc@viewlogic.com.)
1859 Fix some infrastructure to be able to cope with host and target
1860 machines with different sized basic types (ints, ptrs, etc).
1861 (Idea from pierre@la.tce.com (Pierre Willard).)
1863 * values.c (value_from_longest): Rename from value_from_long.
1864 Handle pointer types as well as integers, so that targets with
1865 different pointer sizes from the host can be accomodated.
1866 * breakpoint.c, convex-tdep.c, eval.c, expprint.c, printcmd.c,
1867 valarith.c, valops.c, valprint.c, value.h, values.c: Rename
1868 uses of value_from_long to value_from_longest.
1869 * eval.c, findvar.c, printcmd.c, valarith.c, valops.c: Pass
1870 the correct pointer type to value_from_long{est}.
1872 * doc/gdb.texinfo ($_, $__): Describe types of these variables.
1874 * remote-vx.c: Remove obsolete code for calling functions via
1875 vxworks kludge interface (it referenced value_from_long).
1877 * valops.c (value_string): Find malloc with lookup_misc_func, not
1880 Tue Sep 3 18:37:46 1991 John Gilmore (gnu at cygint.cygnus.com)
1882 Make writing to files work properly. (Fixes to BFD are also needed.)
1884 * core.c (core_open): Open file ourselves, read or r/w, depending on
1885 write_files. Use bfd_fdopenr.
1886 * gdbcore.h (write_files): New variable.
1887 * exec.c (write_files): Define variable, add set&show for it.
1888 (exec_file_command): Use write_files to open for read or r/write.
1890 Make shared library reading happen automatically. These changes
1891 are mostly from Peter Schauer <pes@regent.e-technik.tu-muenchen.de>.
1893 * inferior.h (stop_soon_quietly): Add to exported variables.
1894 * infrun.c (child_create_inferior): call solib hook, if defined.
1895 (child_attach): call solib hook, if defined.
1896 * solib.c: Include inferior.h. Add from_tty to so_list as kludge.
1897 (find_solib): Use lookup_misc_func rather than hand-rolled.
1898 (symbol_add_stub): New stub for catch_errors.
1899 (solib_add): Avoid output if !from_tty. Catch errors rather
1900 than just calling symbol_file_add and bombing.
1901 (solib_create_inferior_hook): Interface with the target process
1902 to let it read and alloc shared libs, then figure out what it did.
1904 * core.c (validate_files): Fix typo, soften warning.
1905 (Fix from Hiroto Kagotani <kagotani@cs.titech.ac.jp>.)
1907 * utils.c (fputs_demangled): Avoid duplicate printing if
1908 demangling is off. (Fix from J.T. Conklin <jtc@cayenne.com>.)
1910 * infrun.c (proceed): Cast -1 to (CORE_ADDR) before comparing.
1911 (Fix from pierre@la.tce.com (Pierre Willard).)
1913 * main.c (catch_errors): Change argument to a char * from an int,
1914 since a char * can point to a struct full of glop, but an int
1915 is not guaranteed to be able to hold a pointer.
1916 * breakpoint.c (breakpoint_cond_eval, bpstat_stop_status,
1917 breakpoint_re_set_one, breakpoint_re_set): Adapt.
1918 * core.c (core_open, solib_add_stub): Adapt.
1919 * remote-vx.c (symbol_stub, add_symbol_stub, callers): Adapt.
1921 Wed Aug 28 18:18:05 1991 John Gilmore (gnu at cygint.cygnus.com)
1923 * Makefile.in: Update VERSION to 4.0.1. Evade GNU Make bug
1924 by adding .NOEXPORT target.
1926 Fri Aug 23 17:14:25 1991 John Gilmore (gnu at cygint.cygnus.com)
1930 * Makefile.in (VERSION): Roll to 4.0.
1931 (gdb.tar.Z): Make refcard.ps as well, for shipment.
1933 Fri Aug 23 14:07:09 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1935 * doc/gdb.texinfo: minor rewordings, crossref to ptype from print,
1938 * doc/Makefile, Makefile.in: generate "gdb-all.texi" rather than
1941 * doc/rdl-apps.texi: renamed from rdl-apps.texinfo
1943 * Makefile.in, doc/Makefile, doc/.Sanitize, doc/gdb.texinfo:
1944 reflect above name change
1946 * WHATS.NEW: correct pointer to refcard.
1948 * doc/gdb.texinfo: update New Features, Installing
1950 * doc/gdbint.texinfo: add short description of configure +template
1952 Fri Aug 23 11:46:08 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1954 * doc/gdb.texinfo: update, fix bugs in "Installing" appendix
1956 Fri Aug 23 01:02:00 1991 John Gilmore (gnu at cygint.cygnus.com)
1958 * Makefile.in: Add config.sub, make doc/rdl-apps.texinfo for
1959 tar file, add dependencies for referenced doc files.
1961 Thu Aug 22 22:17:06 1991 Stu Grossman (grossman at cygint.cygnus.com)
1963 * coffread.c, symfile.c, stack.c: saberized.
1965 Thu Aug 22 16:20:27 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1967 * doc/refcard.tex: permuted Essential Commands sec
1969 * doc/gdb.texinfo: new C++ chapter; revised installation appendix;
1971 set/show symbol-reloading
1972 default set complaints 0
1974 RET-repeat disabled after prompted long displays
1975 processID (attach) interpretation of 2nd GDB cmdline arg
1977 Thu Aug 22 14:05:47 1991 Stu Grossman (grossman at cygint.cygnus.com)
1979 * expread.y, coffread.c, dbxread.c, target.c, mem-break.c,
1980 cplus-dem.c, values.c, valprint.c, symfile.c, remote.c,
1981 breakpoint.c, main.c: lint.
1983 Thu Aug 22 02:02:26 1991 John Gilmore (gnu at cygint.cygnus.com)
1985 Install new configuration scheme for GDB and friends.
1987 * config.sub: Translate ordinary names to three-part names.
1988 * configure: Use three-part names internally.
1989 * configure.in: Translate three-part names to filenames.
1991 * README, WHATS.NEW: Update for gdb-4.0.
1992 * Makefile.in: Roll VERSION to 3.99.
1994 Wed Aug 21 18:21:09 1991 John Gilmore (gnu at cygint.cygnus.com)
1996 * infptrace.c (KERNEL_U_ADDR_BSD): Include a.out.gnu.h.
1997 * i960-tdep.c, m68k-tdep.c, sparc-tdep.c, tm-i960.h,
1998 tm-m68k.h, remote-nindy.c: Change ext_format_XXX structs
1999 to single structures rather than arrays; when passing
2000 their address, use &. This avoids trouble with bdead compilers.
2001 * mcheck.c: Don't include <stdlib.h>; just declare "void abort();"
2002 instead. This avoids portability headaches.
2003 * mips-tdep.c (mips_do_registers_info): Only print FP regs if
2005 * source.c (open_source_file): Avoid ANSI const bdeath by
2006 skipping declaration and then casting result value.
2007 * tm-hp300bsd.h: Clarify comment.
2008 * utils.c (strstr): Result is const char *; ANSI bdeath.
2009 * xm-hp300bsd.h: Define HOST_BYTE_ORDER. Redefine INT_MIN,
2010 since system include file defines it differently from "defs.h",
2011 though the two are equivalent for our purposes.
2012 * tconfig/hp300bsd: Add m68k-tdep.o.
2014 Tue Aug 20 16:01:11 1991 John Gilmore (gnu at cygint.cygnus.com)
2016 * tconfig/sun*4: Remove warnings about system assembler.
2018 Mon Aug 19 13:44:46 1991 John Gilmore (gnu at cygint.cygnus.com)
2020 * mcheck.c: Avoid warning about undeclared abort fn.
2021 * tm-sparc.h (PC_ADJUST): Avoid calling error() from this;
2022 it causes recursive calls to error() when used in cleanups.
2023 To do so requires that we make it a function, so we do.
2024 * sparc-tdep.c (sparc_pc_adjust): New implem of PC_ADJUST.
2025 * utils.c (do_cleanups): Remove the current cleanup from the
2026 chain *before* calling it, in case error() is called from it.
2027 The result won't be pretty, but won't be an infinite loop either.
2029 Mon Aug 19 00:41:04 1991 Michael Tiemann (tiemann at cygint.cygnus.com)
2031 * dbxread.c (read_struct_type): Grok anon structs for C++.
2032 (vb_name, vptr_name): Null terminate these strings.
2034 Fri Aug 16 08:31:03 1991 John Gilmore (gnu at cygint.cygnus.com)
2036 Minor bug fixes from BSD Net2 gdb:
2038 * blockframe.c (get_prev_frame_info): If FRAME_CHAIN_COMBINE
2039 returns 0, there is no previous frame.
2040 * breakpoint.c (commands_command): If !from_tty, don't call
2041 input_from_terminal_p().
2042 * dbxread.c (record_misc_function): Speed up slightly.
2043 (compare_psymbols): Ditto.
2044 * infcmd.c (do_registers_info): Take a second argument to
2045 determine whether to print float registers. "info registers"
2046 does not do so anymore. "info all-registers" does, now.
2047 * mips-tdep.c, pyr-tdep.c (xxx_do_registers_info): Take second
2049 * tm-mips.h, tm-pyr.h (DO_REGISTERS_INFO): Pass second arg.
2050 * inflow.c (initialize_inflow): Set tflags_ours correctly.
2054 * breakpoint.c (bpstat_do_actions): Use a cleanup to restore
2055 executing_breakpoint_commands if we are interrupted by error.
2056 * coffread.c (init_lineno): Avoid problem with zero-sized linetab
2057 versus malloc/free. From: john@labtam.labtam.oz.au (John Carey).
2058 * core.c (solib_add_stub, core_open): Call SOLIB_ADD inside a
2059 catch_errors() so we can setup the frame regardless of whether
2060 the shared libs work.
2061 * ieee-float.c (double_to_ieee_extended): Get exponent from
2062 right place in little-endian systems. From John Carey.
2064 Thu Aug 15 18:43:57 1991 John Gilmore (gnu at cygint.cygnus.com)
2066 * main.c: Remove unused terminating_signals and catch_termination().
2067 (long_options): Terminate with a zero element.
2068 [Bugfix from Atsuo Kawaguchi <atsuo@hark86.harl.hitachi.co.jp>.]
2069 (gdb_readline): Make call-compatible with readline.
2070 (init_signals): Improve comments re vfork vs. signal.
2072 * utils.c (prompt_for_continue): Use new gdb_readline().
2073 If we prompt for continuation, we don't let CR repeat the previous
2074 command, once we get back to a prompt. It's too easy to keep
2075 hitting CR, expecting "--more--" prompts, and have some long
2076 command start repeating on you.
2078 Tue Aug 13 16:17:56 1991 John Gilmore (gnu at cygint.cygnus.com)
2080 * blockframe.c (frameless_look_for_prologue): Speed up by
2081 calling SKIP_PROLOGUE_FRAMELESS_P if it's defined.
2082 * tm-sparc.h (SKIP_PROLOGUE, SKIP_PROLOGUE_FRAMELESS_P):
2083 Define two variants, one faster.
2084 * sparc-tdep.c (sparc_frame_chain): Use target_read_memory
2085 and return zero, rather than giving an error.
2086 (setup_arbitrary_frame): Initialize the PC in the new frame.
2087 (skip_prologue): Add a second arg saying whether we're just
2088 checking for a frameless function or not.
2090 * core.c (core_open, core_close, core_xfer_memory): Move
2091 section table pointers and bfd* into the target_ops.
2092 (core_open): Allow errors in shared lib reading, etc.
2093 (core_files_info): Describe shared library sections.
2095 * exec.c (exec_open, exec_close, exec_xfer_memory, xfer_memory,
2096 exec_files_info, set_section_command): Move section table
2097 pointers and bfd* into the target_ops.
2098 (add_to_section_table): Add BFD to section table.
2100 * target.c (target_xfer_memory, target_info): Pass target to
2101 xfer_memory and target_info functions.
2104 * gdbcore.h: Move struct section_table.
2105 * target.h: New home of struct section_table.
2107 * solib.c (solib_add): New argument is the target_ops whose
2108 section list is to be added to, if any. Reallocate the
2109 sections in that target to add any that come from shared libs.
2110 (throughout) so_sections renamed to sections.
2111 (solib_xfer_memory): Deleted.
2112 * tm-sunos.h (SOLIB_ADD): Add target argument.
2113 (SOLIB_XFER_MEMORY): Delete.
2115 * core.c, exec.c, inftarg.c, remote-eb.c, remote-nindy.c,
2116 remote-vx.c, remote.c, target.c, target.h: Remove add_syms vector
2117 from target_ops. It's the same on all targets. Add two section
2118 pointers to target_ops.
2120 * stack.c (find_relative_frame): Dump ancient algorithm for
2121 "down", just use handy "next" pointers.
2122 (frame_command): Don't error if there is no stack; let user
2125 * inflow.c (new_tty_prefork, new_tty): New prefork routine
2126 modifies static state in the parent process; new_tty itself
2127 runs in the child and modifies the child's file descriptors
2128 to match the saved static state.
2129 * infrun.c (child_create_inferior): Call new_tty_prefork,
2132 * infptrace.c (child_xfer_memory): Add ignored target arg.
2133 * remote-eb.c (eb_xfer_inferior_memory): ''
2134 * remote-nindy.c (nindy_xfer_inferior_memory): ''
2135 * remote-vx.c (vx_xfer_memory): ''
2136 * remote.c (remote_xfer_memory): ''. Rename from
2137 remote_xfer_inferior_memory.
2139 * main.c (main): Only try to attach "corefile" argument if
2140 it starts with a digit.
2142 * symfile.c (symbol_reloading): New "set/show" variable.
2143 (symbol_file_add): Shorten message about symbol reading.
2144 (add_symbol_file_command): Merge with add_syms_addr_command,
2145 since this should work on all targets now.
2146 (stop_whining): Default to zero, to shut up complaints
2147 about bad symbol tables on many systems.
2148 (free_named_symtabs): Just exit unless symbol_reloading.
2150 * xm-sun3os4.h, xm-sun4os4.h: Define BROKEN_LARGE_ALLOCA,
2151 and add comment explaining shared library screw.
2153 * source.c: #if defined => #ifdef.
2155 Thu Aug 8 12:23:19 1991 John Gilmore (gnu at cygint.cygnus.com)
2157 * doc/gdbint.texinfo: Improve doc on porting to new OS's.
2159 Tue Aug 6 17:16:15 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
2161 * doc/rdl-apps.texinfo: provide default readline-appendix finder
2162 (doc/Makefile knows how to make one for local config)
2164 * Makefile.in: use doc/Makefile for doc targets
2166 * doc/Makefile: GDB documentation now has its own Makefile
2167 doc/refcard.tex: renamed from "gdbrc.tex"
2168 doc/.Sanitize: add Makefile; recognize renamed refcard.tex
2169 doc/gdbint.texinfo: add markup in "Cleanups" chapter
2172 Fri Aug 2 00:13:06 1991 John Gilmore (gnu at cygint.cygnus.com)
2174 * values.c (baseclass_addr): When reading target memory, use the
2175 length of the basetype, not the upper type. We've only malloc'd
2176 enough space for the basetype, leading to errors in free().
2178 * expprint.c (print_subexp): Print UNOP_MEMVAL of an OP_LONG that
2179 ends up as a function specially, since we know the actual type of
2180 the pointed-to address. This (somewhat) fixes display of
2181 expressions that include misc_function_vector names. Try `cond 1
2182 !strcmp("a","b")' then `i b'.
2184 * infrun.c: Move DO_DEFERRED_STORES from proceed() to resume().
2185 The child can be proceeded from inside wait_for_inferior in
2186 evaluating breakpoint conditions, and DO_DEFERRED_STORES was
2187 getting skipped in that case.
2189 * expprint.c (print_subexp): Use filtered output, since the
2190 subroutines we call use it, otherwise the output is horribly
2191 mangled, since output of wrappable stuff comes out late.
2193 * Makefile.in: Bump VERSION to 3.98.1
2195 * infrun.c (child_create_process): Use execlp to find the
2196 shell to exec our target program. This requires some fiddling
2197 with `environ' since there is no execlpe().
2199 Thu Aug 1 15:35:17 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
2201 * Makefile.in, doc/gdbrc.tex, doc/rc-* (new files):
2202 Minor rearrangement of refcard permits two new make targets--
2203 gdbrc.dvi DVI output for refcard, using CM fonts
2204 gdbrc.ps PostScript refcard, using PS fonts
2206 Wed Jul 31 16:46:21 1991 John Gilmore (gnu at cygint.cygnus.com)
2210 * TODO, Projects, WHATS.NEW, README: Update for gdb-3.98.
2211 * Makefile.in (gdb-all.texinfo): Avoid touching file if M4 dies.
2213 Wed Jul 31 16:35:58 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
2215 * doc/gdb.texinfo: last changes for release.
2216 Minor typo and formatting fixes; incorporated most fixes remaining from
2217 filed mail commenting on earlier drafts.
2219 Added warnings: pipes don't work in run command;
2220 conditions are converse of assertions;
2221 step over fn without debug info goes to next fn;
2222 vars may have "wrong" values near fn entrance, exit
2224 Added example from Kingston on printing repeated nonadjacent values
2226 Added explicit mention that in Emacs gdb mode C-c and C-z are like
2227 shell mode for signals
2229 Renamed "Stepping and Continuing" to "Continuing and Stepping" so it
2230 doesn't sound so much like its parent "Stopping and Continuing"; also
2231 moved entries on continue to top of section, so they don't get lost.
2233 Improved installation directions in appendix, added manual formatting
2236 Tue Jul 30 17:26:39 1991 John Gilmore (gnu at cygint.cygnus.com)
2238 * configure.in: Remove xm.h and tm.h even if we aren't linking
2239 new ones, so "./configure sun4; ./configure none" does the right
2240 thing. Assume that alldeps.mak and depend are already built in
2241 srcdir, and avoid running "make" (particularly "make depend",
2242 which involves "gcc") from inside configure. Build Makefile
2243 directly rather than building Makefile.conf first.
2244 * configure: Regenerate with above changes.
2245 * Makefile.in: Use $(BISON) to find bison. Roll VERSION
2246 to 3.98. Revise gdb.tar.Z procedure to produce a file
2247 called gdb-$(VERSION).tar.Z but which unpacks into a
2248 directory called "gdb". Move non-source files out of
2249 $(SFILES_SUBDIR). Pretty up alldeps.mak with comments.
2250 (depend): Don't try to do "gcc expread.y".
2251 (expread.o): Update dependencies by hand.
2253 Mon Jul 29 15:21:09 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
2256 Fixed a variety of small typos that prevented info from formatting
2257 cleanly; altered too-long heading for GPL Appendix, as discussed
2258 w/RMS; Changed date on cover to July 91.
2260 Fri Jul 26 13:20:02 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
2263 (1) Applied some fixes due to comments from Larry Breed (easier ones
2264 through chapsec 5.2)
2265 (2) Eliminated use of @footnote---had my doubts about it anyways, and
2266 it's broken in latest texinfo
2267 (3) Introduced *some* use of [] for optional arguments, where
2268 explanation is not simpler by listing cmd w arg and cmd w/out arg
2269 separately. Still not using @deffn.
2270 (4) Dropped in GPL-2. NOTE: one of GPL-2 or texinfo is broken; a
2271 couple of headings are too long. Need patches to texinfo or revision
2274 * Partial update to README (which still needs work for this
2275 release!): (1) use of configure corrected for new script,
2276 (2) "make gdb.dvi" and "make gdb.info" mentioned.
2278 Wed Jul 24 06:44:02 1991 John Gilmore (gnu at cygint.cygnus.com)
2280 * symtab.c (lookup_symbol): Don't complain right off about
2281 no debug symbols; use the misc function vector first.
2282 (list_symbols): Use misc function vector to find symbols
2283 that don't have debug info, and print them.
2284 (find_pc_symtab): Temporarily avoid fatal() when psymtab
2285 PC range doesn't match symtab PC range, as it does on the
2286 MIPS because our symtab reading isn't perfect.
2288 * dbxread.c (dbx_symfile_read): Make warning about
2289 "no debug symbols" slightly nicer.
2291 * source.c (select_source_symtab): If "main" symbol exists,
2292 but decode_line_spec can't find line info, don't just return
2293 a zero; try other source symtabs or give an error.
2295 * mipsread.c (parse_partial_symbols): Sort the psymtabs by
2296 their low addresses first, then rip through fixing high addrs.
2298 * ns32k-opcode.h (sfsr): Bugfix from Rune Nerg}rd,
2299 <runene@ifi.uio.no>.
2300 (NS32K_SVC_IMMED_OPERANDS): Reverse the #ifndef.
2302 Tue Jul 23 18:52:43 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
2304 * Minor, mostly mechanical, cleanup of doc subdir for clean
2305 makeinfo'ing and TeXing; also ensured gdb-all.texinfo (post-m4)
2306 and gdb.info (post- texinfo2 makeinfo) generated for distribution.
2308 Sun Jul 21 03:54:52 1991 John Gilmore (gnu at cygint.cygnus.com)
2310 Mostly MIPS and general symbol-reading fixups.
2312 * doc/gdbint.texinfo: Add documentation on symbol-reading
2315 * mipsread.c: Remove kludges around #include "ecoff.h".
2316 Remove redefinitions of a_magic, etc, no longer used.
2317 (parse_symbol, ): Convert "Internal:" printfs to complain()ts.
2318 Fix global overview comments to match symfile.c protocol.
2319 (mipscoff_new_init): Eliminate cur_hdr if we have one.
2320 (mipscoff_symfile_read): Eliminate unused code. Avoid
2321 sorting all the symtabs, when all we have read here is psymtabs.
2322 The symtabs are sorted as they are created anyway. Tell
2323 condense_misc_bunches whether we're mainline.
2324 (psymtab_to_symtab_1): Pass filename when recursing, to make
2325 stack trace more informative.
2326 (parse_partial_symbols): Assume cur_hdr as argument.
2327 (read_mips_symtab): Don't clobber cur_hdr, so it can be freed.
2328 Pass cur_hdr implicitly to parse_partial_symbols. Avoid checking
2329 the TYPE_NAME of char *, since that's done in symfile.c.
2330 (free_numargs, parse_symbol, add_symbol, add_block,
2331 shrink_linetable): Declare these fns void.
2332 (upgrade_type): Convert tree of if's to switch. Clean up
2333 bogus "off == 0" handling with a complaint. Avoid setting
2334 field bitpos and bitsize of array with lower and upper bounds.
2335 Check specified bitsize of elements against their actual type's
2336 bitsize, and complain if different. Complain about unknown
2338 (parse_fdr): Don't assume sizeof(char *) == sizeof (struct *).
2339 (psymtab_to_symtab_1): Print names of subsidiary files that
2340 are being read in. FIXME, we read far too many files. This code
2341 is not the problem, the problem is in parse_fdr where the psymtabs
2343 (cross_ref): Result should indicate that we used one aux entry
2344 normally, or two if we encountered a "next" entry. This used
2345 to leave the caller pointing at the wrong aux entry.
2346 (add_symbol): If overflowed cur_block, reallocate it larger,
2347 chase all pointers to it, and complain(), rather than clobber memory.
2348 (shrink_block): Use xrealloc rather than xmalloc-and-copy.
2349 (new_field): Only allocate one field initially, not two.
2350 Pull ++ out of macro argument. Simplify.
2351 (_initialize_mipsread): Avoid initialization of importd
2352 global_psymbols and static_psymbols.
2354 * symfile.c (psymtab_to_symtab): Depend on XXX_psymtab_to_symtab
2355 to properly set pst->symtab; avoid searching for it.
2356 (symfile_fns): Improve comments, add a FIXME.
2357 * dbxread.c: Update comments to reflect symfile protocol.
2358 (read_ofile_symtab, end_symtab): Return the symtab.
2359 (psymtab_to_symtab_1): Set pst->symtab.
2361 * coffread.c (coff_symfile_read): tell condense_misc_bunches
2362 whether we're mainline.
2364 * symfile.h (sym_fns): Remove unused sym_discard member.
2365 * coffread.c, mipsread.c, dbxread.c: Remove XXX_symfile_discard.
2367 * mtrace.c (mtrace): Take effect if mallwatch is set, even if
2368 the environment variable is not.
2369 * infcmd.c (finish_command): Use filtered printfs.
2370 * cplus-dem.c: Add struct tags to a few unnamed structs.
2371 * valops.c (value_coerce_array): Improve comments.
2372 * valprint.c (type_print_varspec_suffix): Print array size only
2373 if greater than zero.
2374 * m88k-tdep.c: Shift some lines left by one space, that had
2375 apparently been trashed at some point.
2376 * TODO: More things to do, a few got done.
2378 Thu Jul 18 22:46:05 1991 John Gilmore (gnu at cygint.cygnus.com)
2380 * symtab.h (LOC_EXTERNAL): Eliminate in favor of LOC_STATIC.
2381 (ldsymoff, ldsymlen, globals_offset, statics_offset): Improve
2383 * dbxread.c (read_dbx_symtab): LOC_EXTERNAL -> LOC_STATIC.
2384 * expread.y, findvar.c, symmisc.c: Ditto.
2385 * printcmd.c (address_info): Update printed forms of LOC_
2386 symbols. Elim LOC_EXTERNAL.
2387 (print_frame_args): Keep track of param stack offsets before
2388 re-looking up to find the local register param is kept in.
2390 * mipsread.c: Use <symconst.h> and <sym.h> rather than <syms.h>.
2391 Further integration of mipsread into gdb. Eliminate unused
2392 routines, duplicate declarations. Handle static symbols in
2393 psymtabs as well as external symbols. When reading symtabs,
2394 insert symbols into the correct block (global, static, or a local
2396 (read_mips_symtab, parse_partial_symbols): Don't pass useless
2398 (mipscoff_symfile_read): Don't call select_source_symtab.
2399 (parse_symbol): Use SYMBOL_VALUE_ADDRESS where appropriate,
2400 rather than SYMBOL_VALUE.
2401 (parse_external): Comment clobbering of top_stack.
2402 (parse_partial_symbols): Update comments. Allocate and parse
2403 static symbols as well as external symbols. FIXME, enum values
2404 are not handled in this pass, but should be. Inline new_psymbol.
2405 Use SYMBOL_VALUE_ADDRESS.
2406 (psymtab_to_symtab_1): Read symbols into global static block
2407 by default (until enter some function's local block context).
2408 (sort_blocks): Clean up STATIC_BLOCK as well as GLOBAL_BLOCK.
2409 (destroy_all_symtabs, new_psymbol): Eliminate, unused.
2411 * source.c (select_source_symtab): Select a source symtab
2412 from either the symtabs or, failing that, the psymtabs.
2413 (list_command): Update error message.
2414 (forward_search_command, reverse_search_command): Use getc, not
2415 fgetc, for speed. FIXME, add comment about buffers that die if
2416 overrun by long line.
2418 * values.c (unpack_field_as_long, modify_field): Avoid shifting
2419 by an entire word, which is not portable, if we have a 32-bit
2420 field. (Code in dbxread.c already turns such bitfields, if
2421 aligned, into ordinary ints, but fixing this will help for other
2422 symbol formats and for future changes.)
2423 * core.c (core_open): Handle ANSI const brain death.
2424 * utils.c (vprintf): Fix varargs typo.
2426 Sun Jul 14 00:42:53 1991 John Gilmore (gnu at cygint.cygnus.com)
2428 * findvar.c (find_var_value): Handle &function better.
2429 * TODO: Document work needed on &fn and &array.
2430 * printcmd.c (print_address_symbolic): New arg is the prefix
2431 to print if a name is printed.
2432 (print_address_demangle): Honor "set print address" now.
2433 Use new arg above to improve spacing of output.
2434 * valprint.c (val_print): When printing function pointers,
2435 print symbolic form too.
2436 * breakpoint.c (breakpoint_1): Use new print_address_symbolic.
2438 Mon Jul 8 19:02:46 1991 John Gilmore (gnu at cygint.cygnus.com)
2440 * core.c (memory_error): Reword error msg to mislead less.
2442 * mips-pinsn.c (print_insn_arg 'd'): Print $ with reg name.
2444 * mipsread.c (read_mips_symtab, read_the_mips_symtab,
2445 parse_partial_symbols): Use newer BFD internals (external_filehdr
2446 and external_aouthdr), byte-swap the fields that we care about
2447 before using them, and make the file header data local to
2448 read_the_mips_symtab rather than global.
2450 Sat Jul 6 01:34:15 1991 John Gilmore (gnu at cygint.cygnus.com)
2452 * ns32k-opcode.h (movmw, movmd): Fix opcodes. Bug fix
2453 from Rune Nerg}rd <runene@ifi.uio.no> on 5 Jul 1991.
2455 * main.c (command_line_input): Flush stdout and stderr
2456 before every call to readline. This reportedly fixes a bug
2457 that comes up in Sys V running emacs-gdb and/or xxgdb,
2458 when stdin/out are pipes or sockets.
2460 Thu Jul 4 14:47:06 1991 John Gilmore (gnu at cygint.cygnus.com)
2462 * configure.in, Makefile.in: Avoid rebuilding "depend" as much.
2463 Avoid declaring Makefile dependencies, because GNU Make stupidly
2464 tries to update it if we do.
2466 * coffread.c: Revise for minor changes to bfd internal coff
2469 * configure: If -template= is given a relative path, make it
2470 absolute before recurring in subdirectories.
2472 * configure, configure.in, Makefile.in: Install "configure" script
2473 as replacement for config.gdb.
2474 * config.gdb, Makefile.dist, Makefile.sdir: Remove
2475 * README: Update for configure, mostly. FIXME.
2477 * Add dec3100 as equivalent to littlemips. Indicate in all host &
2478 target config files that they are for the host. When the lines
2479 get copied into the Makefile, this makes it more obvious what's
2482 Mon Jun 24 23:49:07 1991 John Gilmore (gnu at cygint.cygnus.com)
2484 * sparc-opcode.h (trap opcodes): Avoid leading spaces or
2485 tabs, which end up in the disassembler output inadvertently.
2487 Wed May 29 23:01:03 1991 John Gilmore (gnu at cygint.cygnus.com)
2489 Make it compile cleanly in an ANSI GCC2 environment.
2491 * blockframe.c: <stdio.h>
2492 * cplus-dem.c: free takes a void *, ifdef __STDC__
2493 * dbxread.c (read_huge_number): avoid gcc2 bug hoisting calc of
2495 * defs.h (alloca): Avoid doing anything if alloca already def'd.
2496 * stddef.h, stdlib.h: Remove these files.
2497 * symtab.c: Avoid declaring qsort, close.
2498 * symfile.c: Avoid declaring close.
2499 * utils.c (vprintf): Declare "ap" arg as proper va_alist.
2500 * sparc-tdep.c: Avoid including lots of Sun-host-specific files.
2502 Assorted other changes.
2503 * dbxread.c: include "libaout.h", not "liba.out.h".
2504 * printcmd.c (print_frame_args): Set recurse properly for
2505 indentation of struct and array parameters.
2506 * valops.c (value_cast): Allow cast to void.
2507 * infrun.c (resume): If NO_SINGLE_STEP, call machine dependent
2508 single_step() in a target-independent fashion.
2509 * sparc-tdep.c (single_step): Don't call ptrace ourselves, just
2510 set up to be ready to continue. This makes us target independent.
2511 * infptrace.c (child_resume): Remove call to single_step; now
2512 can single step a SPARC target of any kind.
2514 Wed May 22 18:18:24 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
2516 * Makefile.dist, doc/gdb.texinfo, doc/*-m4.texinfo: split up GDB
2517 docn into separate sections---basically chapters, plus two loose
2518 pieces that can be configured to go in different places. This
2519 allows GNU m4 to preprocess the manual without coredumping.
2521 * Makefile.dist: tell TeX where to find texinfo.
2523 Mon May 20 12:15:04 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
2525 * Makefile.dist, doc/gdb.texinfo: respectively create, and use,
2526 the new target "rdl-apps.texinfo" which captures the Makefile
2527 variable that records where to find the Readline libraries.
2529 Sun May 19 05:36:59 1991 John Gilmore (gnu at cygint.cygnus.com)
2531 * tahoe-pinsn.c: #include "tahoe-opcode.h", not "opcode.h".
2532 * tm-tahoe.h (FIX_CALL_DUMMY): Ignore more parameters.
2533 * defs.h (const, volatile): Only define if not already defined.
2534 * Makefile.dist (gdb.tar.Z): Create doc subdir w/out CVS/RCS crud.
2536 * README: Update for release 3.95.
2537 * config.gdb: Don't create readline dir in subdir builds.
2538 * main.c: Include with "..." form for non-system include files,
2539 so "gcc -MM" for "make depend" works.
2540 Include readline files with "...h" rather than <readline/...h>.
2541 * mipsread.c: Include "ecoff.h" rather than "intel-coff.h".
2543 * coffread.c: Undo minor damage done by Rich Pixley. Use
2544 different internal and external representations of COFF
2545 data structures. Use new BFD routines for swapping them in and
2547 * symfile.c (free_named_symtabs): Avoid freeing file names that
2548 are null or empty. Old i960 tools seem to produce files that
2549 claim to have empty names, causing each successive file read
2550 to blow away the previous one.
2551 * sparc-xdep.c (deferred_stores): Repair minor damage by Rich.
2552 Move deferred_stores to top of file, but don't separate its
2553 #define's from its variable. Add commentary.
2554 * Makefile.dist: Fix Rich damage; undo "configure" changes in
2555 favor of keeping the (working) config.gdb. Move readline
2558 Fri May 17 12:49:56 1991 Per Bothner (via gnu at cygint.cygnus.com)
2560 * dbxread.c (read_struct_type): Try to handle g++ version 1 MI
2562 * infptrace.c (fetch_registers): no result, since now void.
2563 * tconfig/news: target depends on m68k-tdep too.
2565 Fri May 17 14:40:14 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
2567 * Makefile.dist: added readline/inc-*.texinfo to dependencies for
2570 * readline/inc-history.texinfo, readline/inc-readline.texinfo:
2571 applied various small fixes due to or inspired by RMS comments
2573 * doc/gdb.texinfo: finished using all RMS comments, save those for
2574 appendices on readline and cmd history (which are in other source
2577 Thu May 16 18:06:05 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
2579 * doc/gdb.texinfo: (1) Updated w/ref to RMS comments through
2580 chapter 9; (2) documented 'break' command's menu mode for
2581 overloaded names, in response to hgs problem report C++ p-31
2583 Wed May 15 11:02:48 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
2585 * doc/gdb.texinfo: (1) better introductory example; (2) more
2586 consistent use of @code, @samp, @file, @kbd throughout; small
2587 cleanups to first three nodes; (3) new "Contributors" node;
2588 (4) Appendix, Renamed Commands; (5) divert specialized startup
2589 instructions to "Targets" chapter for generic manuals, while
2590 leaving them up front for manuals specific to specialized
2591 environments; (6) apply fixes from RMS comments through chapter 4.
2593 * pretex.m4: modify explanatory text slightly (and redefine
2594 "regexp") to keep GNU m4 from complaining. (It still crashes
2595 later, but one step at a time...)
2597 Wed May 15 10:32:12 1991 John Gilmore (gnu at cygint.cygnus.com)
2599 * readline/readline.c (update_line): Avoid dereferencing a pointer
2600 before comparing it to its bounds. Saber caught this.
2601 (init_terminal_io): Don't set BC from the "pc=" termcap variable,
2602 and only set PC if tgetstr returned non-null. Saber caught this.
2604 Tue May 14 16:29:53 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)
2606 * Makefile.dist: put gdb.dvi stuff (updated to use M4 preprocessor
2607 stuff for config manual) here where it counts; updated
2608 to use new subdir structure (gdb/doc/).
2610 * Makefile: generated from above via
2614 * gdbint.texinfo: added instructions on generating gdb.info* files
2615 locally for release. These are ordinary info
2616 files, formatted from gdb.texinfo (via gdb-all.texinfo, see
2617 Makefile)---but due to use of texinfo 2, can't count on makeinfo
2618 to generate these, so we distribute them already formatted.
2620 * gdb.texinfo: included full Info node and menu crud (as generated
2621 by C-u M-x texinfo-master-menu using the texinfo-2 elisp code).
2623 * Makefile: updated "gdb.dvi" target to use M4 preprocessor;
2624 put in comments-for-future gdb.info target (one day makeinfo will
2627 Tue May 14 13:51:36 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)
2629 * gdb.texinfo: Updated to include new or old undocumented
2630 commands, at least the following (perhaps some others I forgot to
2631 record): info f, info float, info path, info program, info s, info
2632 set, info source, info terminal, info types, info user, set/show
2634 Also covered all recent GDB command renames for v4.
2636 Mon May 13 14:57:46 1991 John Gilmore (gnu at cygint.cygnus.com)
2638 * mipsread.c: Rather than keeping count of how many symtabs
2639 and psymtabs we have, for sorting purposes, count them when
2640 we need to sort. This fixes bug in rereading of symbol tables.
2642 Fri May 10 15:43:33 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)
2644 * infcmd.c: renamed "info path" to "show paths"

2659 symtab.h, target.c, target.h: Lint.
2660 * core.c: setup and select frame after reading shared libs,
2661 else reading shared libs will clobber them. Lint.
2662 * utils.c (error): Force out any buffered wrap text.
2664 Fri May 3 22:01:56 1991 John Gilmore (gnu at cygint.cygnus.com)
2666 * remote.c: Remove decls of memory_insert_breakpoint
2667 and memory_remove_breakpoint, no longer used. (Suggestion of
2670 * Makefile.dist: use ${subdir} in paths of BFD and LIBIBERTY,
2671 to make it easier to interface to "configure"'d libraries.
2673 Fri May 3 13:10:01 PDT 1991 Roland Pesch (pesch at fowanton.cygnus.com)
2675 * valprint.c: introduce "set p", "set pr", "show p" and "show pr" as
2676 aliases for set/show print.

2737 * signame.c: Cast const char* to char* when assigning to sys_siglist.
2739 * utils.c (strsave): Make arg const char* not char*.
2741 * infrun.c (wait_for_inferior) [SHIFT_INSN_REGS]: Use

2765 * infptrace.c (PT_WRITE_D, PT_READ_D): Use correct values.
2766 (This still doesn't seem to make MIPS bkpts work.)

2802 : Lint. Use read_memory not read_memory_integer on CORE_ADDR's.
2803 Use {value_as,unpack}_pointer (added to values.c)
2804 not {value_as,unpack}_long on CORE_ADDR's.
2805 Use longest_to_int (added to defs.h) instead of cast to int.
2806 Remove from_tty arg to mod_path.
2807 Put symfile_bfd in {coff,dbx}read.c not symfile.h.
2808 Use OP_NULL instead of 0 where dummy enum exp_opcode needed.

2883 rather than smash_to_method_type.
2884 symtab.c, symtab.h (allocate_stub_method): New function.
2885 dbxread.c (read_type): If we get "##", don't lookup_function_type
2886 and start clobbering it; allocate_stub_method instead.
2887 * printcmd.c (x_command): Dereference references.
2888 * valprint.c (type_print_varspec_prefix, case TYPE_CODE_METHOD):
2889 Don't print " " type_print_base (...) "::" if !passed_a_ptr.

3280 * exec.c (exec_ops): Add_syms_addr is valid in our tvec.
3281 (set_section_command): New command ("section xxx yyy" -- should
3282 be renamed to "set section xxx yyy" FIXME) which sets the
3283 base address of a section of the exec file, overriding the
3284 virtual address that BFD reports.
3286 Fri Apr 5 17:14:39 1991 John Gilmore (gnu at cygint.cygnus.com)
3288 * exec.c: Add add_syms_addr_command to exec_ops, so you can

3293 * tm-i386v.h (FLOAT_INFO): Don't define it, since the code
3294 for printing the float info is host-dependent, not
3295 target-dependent. FIXME.
3296 * i386-pinsn.c: Move #includes to top, remove useless ones.
3297 * i386-tdep.c: Don't bother including <.../reg.h> since we

3309 * remote-nindy.c (nindy_detach): Don't need dont_repeat() now.
3310 * expprint.c (print_subexp): Avoid switch fallthru on

3312 * frame.h: Fix typo.
3313 * inflow.c (kill_command): After killing inferior, print our
3314 current frame in the core file, if we have one.

3317 set both the current and selected frames to NULL.
3319 Changes from Peter Schauer.
3321 * infptrace.c: Avoid <sys/ptrace.h> on USG.
3323 * Make all file names fit in 14 characters (sigh and damn!):

3342 Wed Apr 3 15:00:26 1991 John Gilmore (gnu at cygint.cygnus.com)
3344 * dbxread.c (really_free_pendings): Clear file_symbols
3345 and global_symbols after freeing them; otherwise, running
3346 this function twice (if it appears twice on the cleanup
3347 chain), we try to free things twice.
3349 * dbxread.c (read_dbx_symtab): Calculate end_of_text_addr
3350 based on text_addr (the address of text in core), not on addr (the
3351 offset between text in the .o file and in core). This change
3352 is from Peter Schauer.
3354 * main.c: Define ALL_CLEANUPS as a cast of zero.
3355 (return_to_top_level): Use it.
3356 (main): Do all cleanups after each command run as part
3357 of the gdb startup sequence. Also do all cleanups before
3358 entering the command loop, and every time we exit the command
3359 loop and reenter. Before, the cleanups from the startup sequence
3360 were being left undone until the first error!
3361 (command_loop): Rename do_nothing cleanup to command_loop_marker
3362 so we can see it easily when examining the cleanup chain.
3363 (init_signals): Add another do_nothing for signal handling.
3364 (quit_command): Only try to kill target if it has execution.
3365 Problems in the target stack got us into a state where
3366 inferior_pid was nonzero but none of the targets had execution.
3367 In this state you couldn't exit gdb.
3369 * dbxread.c: Two changes from Peter Schauer.
3370 (echo_command): Fflush output after an echo command.
3371 (show_history): Pass all args to cmd_show_list.
3373 * utils.c (init_malloc): Call mtrace to turn on tracing
3374 if the environment variable MALLOC_TRACE is set to a file name.
3375 * mtrace.c: Add source file which provides a log of every malloc,
3376 free, and realloc to a trace file.
3377 * mtrace.awk: Add source file which analyzes the trace file.
3378 * Makefile.dist (GNU_MALLOC, MALLOCSRC): Add mtrace.{c,o,awk}.
3379 (VERSION): Roll to 3.94.3.
3381 * breakpoint.c (breakpoint_1): Add a space to "i watch" output.
3382 (check_duplicates): Don't bother with watchpoints.
3383 (set_raw_breakpoint): Comment about danger of this routine.
3384 (watch_command): Parse and eval all args before calling
3387 * solib.c (find_solib): Avoid error in referencing memory to
3388 see if any more shared libraries have been added. This is
3389 particularly useful if the target has terminated. Bug reported
3392 Changes from Peter Schauer <pesrem@regent.e-technik.tu-muenchen.de>
3393 in bringing up 3.94.2 on the Sun-3.
3395 * Makefile.dist: Include CFLAGS in rule for cplus-dem.o.
3396 * breakpoint.c (enable_breakpoint): Check for valid watchpoint
3397 expression (in scope) before reenabling watchpoint.
3398 * signame.c (init_sigs): Add missing declaration of i, fix
3399 sys_siglist declaration.
3400 * source.c (list_command): Fixed range computation to use
3402 * stack.c (backtrace_command): Do not allow command if target has
3403 no stack, print informative error message.
3404 * target.c (target_command): Do not write into command line
3405 because this fails if the target command is used in a user defined
3406 command. [This change was enhanced by gnu to support any-
3407 unique-prefix matching on target names.]
3408 * valops.c (value_struct_elt): Avoid infinite loop on an
3409 erroneous attempt to print the member of function (try p main.p).
3411 Mon Apr 1 17:05:45 1991 John Gilmore (gnu at cygint.cygnus.com)
3413 * expread.y (name_no_typename): Avoid reduce/reduce errors
3414 caused by ambiguity in handling NAME_OR_INT and NAME_OR_UINT.
3415 Since the GDB parser really doesn't use name_no_typename in a
3416 name-only context, the parser can't tell the diff between
3417 names and numbers here. Avoid allowing a name_no_typename
3418 to be a NAME_OR_*INT to resolve the conflict.
3420 Sun Mar 31 20:12:07 1991 John Gilmore (gnu at cygint.cygnus.com)
3422 Bugfixes from Mark Fox (markf@wrs.com) (test=testField.c):
3424 * valprint.c (val_print_fields): bitfield printing didn't handle
3425 byte order. Indirect through a few more fns to cope.
3427 * values.c (modify_field): also cope with byte order.
3429 Sat Mar 23 10:02:21 1991 John Gilmore (gnu at cygint.cygnus.com)
3431 Cleanup for release 3.94.2:
3433 * Makefile.dist: Pull REMOTE_OBS. Fix saber includes for BFD
3434 include files. Roll version to 3.94.2.
3436 * coffread.c (init_stringtab): Read length into unsigned char
3437 array before swapping; don't assume 32-bit longs.
3439 * target.c (target_info): Don't bother with get_sym_file, just use
3440 the symfile global variable.
3441 * symtab.h, symfile.c (get_sym_file): Delete it.
3443 * dbxread.c (dbx_symfile_init): Don't depend on long == 4 bytes.
3444 (define_symbol): Set symbol line number to 0 if not gcc-compiled.
3445 (read_type): Replace one more error() with complain().
3447 * mipsread.c (parse_partial_symbols): Replace printf with complain.
3449 * i960-tdep.c: Fix copyright attribution.
3451 * config.gdb: Quote all backquotes in doublequotes. You can
3452 quote me on that. BSD 4.4 shell found this one.
3454 * infptrace.c (throughout): The third argument to ptrace is an
3457 * infrun.c (wait_for_inferior): When program has terminated, we
3458 have to call target_terminal_ours before we pop that target off
3459 the stack (e.g. before a call to target_kill or
3460 target_mourn_inferior). This fixes problem where a program
3461 terminates, then GDB stops for (tty output) and you have to type
3462 "fg" to the shell to resume it. FIXME: This code for what to
3463 do after termination really should be in normal_stop instead.
3465 * gdbcore.h (read_memory_check): Change declaration; it changed
3468 * terminal.h: Include <sgtty.h> before <sys/ioctl.h>, since in BSD
3469 4.4 prereleases, this avoids a bug in their sgtty compatability
3471 * remote.c: Use terminal.h rather than hand-rolling the same.
3473 * signame.c, signame.h (psignal): Arg is unsigned, not int.
3474 * utils.c (strsave, strstr): Fix arg types.
3475 * valprint.c (val_print): lint
3477 MIPS symbol table support from Per Bothner:
3479 * symfile.c (symtab_fns): Remove initializer table that needs to
3480 be hacked for each new symbol file format supported.
3481 (add_symtab_fns): New function, chains symbol table
3482 handlers into the global list.
3483 (symfile_init): Search this list.
3484 * symfile.h: Add next pointer, declare add_symtab_fns.
3485 * coffread.c (_initialize_coffread): Call add_symtab_fns.
3486 * dbxread.c (_initialize_dbxread): Call add_symtab_fns.
3488 * mipsread.c (psymtab_to_symtab_1): return void instead of (struct
3489 symbol *). Thus, we no longer need the hack to trash
3490 pst->filename. Good, since that hack confused code in symfile.c!
3492 (reorder_symtabs, destroy_all_symtabs): Removed static
3493 all_symtabs, which was used to qsort symtabs in reorder_symtabs.
3494 Instead, the latter now uses a temporary array (stack-allocated
3495 from an obstack, and then freed).
3497 (parse_symbol): Added a hack to fix up BLOCK_{START,END} if they
3498 haven't been set in the outermost stBlock of a procedure. This was
3499 a problem with f77 binaries on Ultrix 4.?.
3501 (new_symtab, new_symbol, new_type): Continue changing code to use
3502 obstacks more and otherwise conform to dbxread internal style.
3503 Made the free_code of symtabs be free_linetable (as in dbxread)
3504 instead of free_contents. This implies memory leaks when reading
3505 a new symbol table, until the conversion is finished. Did change
3506 (struct symbol) and (struct type) to be allocated on the
3507 symbol_obstack. Blocks and blockvectors are among the things
3510 * mipsread.c (parse_partial_symbols, parse_fdr): It hasn't been
3511 tested much, but it solved one problem (reported by Meissner), and
3512 cleans up some other things. The problem happened when an
3513 included file contains actual code (functions) and not just
3514 definitions. The mips coff is a little inconvenient there, since
3515 it may cause a procedure to be mapped to the wrong psymtab.
3517 * mips-tdep.c (heuristic_proc_desc): Minor cleanup.
3518 * mips-xdep.c (fetch_core_registers): Minor cleanup. FIXME,
3519 this will need work for the new core paradigm.
3521 Opcode patches from the net:
3523 * mips-opcode.h: fix incorrect disassembly of the mfc1, cfc1, and
3524 ctc1 instructions. Also, the cvt.d.w and cvt.s.w instructions were
3525 missing altogether - they are added here. From Bruce Bauman.
3526 * mips-opcode.h: The low mask for C0 instructions was too small.
3527 From Garrett Lau. I modified the fix to check the entire 32-bit
3530 * ns32k-opcode.h: Fix opcodes for deiw and deid. From Bruce
3533 Thu Mar 21 12:56:46 1991 John Gilmore (gnu at cygint.cygnus.com)
3535 Roll in changes from Per Bothner (Tue, 25 Sep 90 11:11:04):
3537 * dbxread.c (read_type): Pointer subtraction (value_sub in
3538 valarith.c) sometimes failed because the types of the
3539 pointers being subtracted were not identical.
3540 These differed because dbxread.c was allocating pointer types
3541 using dbx_alloc_type+smash_to_pointer_type instead of
3542 lookup_pointer_type. I failed to find a justification for the
3543 former, so I changed it to use the latter. Similarly, I
3544 replaced smash_to_function_type by lookup_function_type,
3545 and smash_to_reference_type by lookup_reference_type.
3547 * mipsread.c (parse_symbol, upgrade_type, parse_procedure,
3548 _initialize_mipsread): corresponding changes.
3550 * symtab.c (smash_to_{pointer,reference,function}_type): eliminate.
3552 * source.c (mod_path): Do tilde_expand on each component of the path,
3553 rather than on the (list of) paths as a whole.
3554 (print_source_lines): Set first_line_listed in addition to
3555 current_source_symtab and current_source_line. If the source was
3556 not findable, after a "dir" command to fix the problem,
3557 a "list" would get the wrong lines.
3559 While I was there... (gnu):
3561 * dbxread.c (read_type): Change error to complaint.
3563 Thu Mar 21 12:56:46 1991 John Gilmore (gnu at cygint.cygnus.com)
3565 First attempt at detailed understanding of symbol table memory alloc.
3567 * dbxread.c (dbx_symfile_read): Free our string table if we
3568 aren't the mainline. Free the "info" struct since we're done with
3570 (init_psymbol_list): Free any previously allocated psymbol lists.
3571 (): FIXME: Should realloc-down the psymbol lists when done reading
3572 the main symbol file?
3574 * symmisc.c (free_symtab): Free fullname field too.
3576 * xm-hp300hpux.h (USG): #undef then #define so Makefile can -D.
3577 (REGISTER_ADDR): Make result type unsigned int.
3579 * xconfig/{i386*,hp300hpux,altosgas,altos}: All config files that
3580 define REGEX must also define REGEX1 (its dependency).
3582 Tue Mar 19 21:28:57 1991 John Gilmore (gnu at cygint.cygnus.com)
3584 * tconfig/i960: No longer works, points you at vxworks960 or
3587 * xgdb.c, XGDB-README: Remove file. Users can get the much
3589 * Makefile.dist: Remove all trace of xgdb.
3591 * breakpoint.c (breakpoint_1): Pass demangle arg to
3592 print_address_symbolic.
3593 (clear_breakpoints): Remove unused function.
3594 (breakpoint_re_set_one): Guts of breakpoint_re_set.
3595 (breakpoint_re_set): Use catch_errors to do them all anyway.
3597 * gdb-int.texinfo (Host versus Target): Add section on what is
3598 a "host" feature versus what is a "target" feature.
3600 * infcmd.c (path_command, path_info): Handle the PATH variable
3601 (object search path) as conveniently as the source search path.
3602 * environ.c (set_in_environ): Set some vars in GDB's environment,
3603 in addition to the child's. PATH, G960BASE, G960BIN for starters.
3604 * source.c (mod_path): New function, from guts of
3605 directory_command, modifies a path. Used by path_command.
3606 (directory_command): Call it.
3607 * defs.h (strsave): Declare.
3609 * utils.c (sevenbit_strings): Add new printing option.
3610 (printchar): Use it.
3611 (strsave): Provide this handy helper routine.
3612 (set_width_command): Rename set_screen_width_command.
3613 (_initialize_utils): "set screen-width" => "set width";
3614 "set screen-height" => "set height"; add sevenbit-strings.
3616 * infcmd.c (do_registers_info): Print floating point registers
3617 in raw hex as well as float format, regardless of whether it is
3618 a "virtual" convertible register.
3619 * tm-sparc.h (PRINT_REGISTER_HOOK): Print every pair of float
3620 regs as a double, just in case it's being used that way.
3621 * values.c (unpack_long): Comment on array/function coercion.
3622 (unpack_double): Argument is in target byte order now. For
3623 integer arguments, just call unpack_long and float the result.
3624 * m68k-tdep.c: include defs.h for "const" handling.
3625 * remote-nindy.c: Use ieee-float stuff.
3626 (nindy_fetch_registers): Unpack double regs to host double, then
3628 (nindy_store_registers): Pack extendeds to host double, flip
3629 around by misusing unpack_double, send as target double.
3631 * tm-vxworks68.h (FRAME_CHAIN): Handle current frame pointer of
3632 zero, as when stopped at the first instruction of a process.
3634 * blockframe.c: Fix filename in comment (param.h => tm.h).
3635 * sparc-tdep.c (skip_prologue): More explicit nudging comments.
3636 * tm-68k.h: Fix typos.
3638 Fri Mar 15 01:09:34 1991 John Gilmore (gnu at cygint.cygnus.com)
3640 Changes from a bringup on the DEC Vax under Ultrix 4.0.
3642 * coredep.c (fetch_core_registers): Pass end-address of register
3643 section to register_addr as expected. Don't call supply_register
3644 if we'd just pass it garbage.
3646 * dbxread.c (read_dbx_symtab): Skip N_NSYMS on Ultrix.
3648 * exec.c (xfer_memory): Use boolean xfer_fn result, not int.
3650 * target.c (push_target, target_info): Cast enums to int for < or
3653 * stack.c (print_frame_info): Identify source file & line
3654 even if we can't print it.
3656 * xm-vax.h (MISSING_VPRINTF): No longer missing in Ultrix V4.0.
3658 Sat Mar 9 10:08:20 1991 John Gilmore (gnu at cygint.cygnus.com)
3660 Clean up IEEE floating point support.
3662 * ieee-float.h: New file.
3663 * ieee-float.c: Write real routines to convert between host
3664 doubles and various target IEEE extendeds.
3665 * m68k-xdep.c: Eliminate assembler code for extended floats.
3666 * xconfig/{3b1,altos,altosgas,hp300bsd,isi,news,news1000,sun2os3,
3667 sun2os4,sun3,sun3os3,sun3os4}: Eliminate use of m68k-xdep.o.
3668 * tm-i960.h, tm-68k.h (REGISTER_CONVERT_TO_VIRTUAL,
3669 REGISTER_CONVERT_TO_RAW): Use ieee_extended_to_double and
3670 double_to_ieee_extended.
3671 * i960-tdep.c: Define ext_format_i960.
3672 * m68k-tdep.c: Define ext_format_68881.
3673 * sparc-tdep.c: Define ext_format_sparc, though unused.
3674 * Makefile.dist (HFILES): Add ieee-float.h.
3675 * inftarg.c: #include "ieee-float.h" for the REGISTER_CONVERT
3678 Obsolete the "coffstrip" program in favor of using BFD's strip.
3680 * nindy-share/coffstrip.c: Remove file.
3681 * nindy-share/nindy.c (coffstrip): Routine to run bfd_strip.
3682 * Makefile.dist: Remove references to nindy-share/coffstrip.c.
3683 * tconfig/nindy960: Remove reference to coffstrip.o.
3685 * Makefile.dist: Roll version number to 3.94.1 (not yet final).
3687 Wed Mar 6 09:56:45 1991 John Gilmore (gnu at cygint.cygnus.com)
3689 * symfile.h: Add symfile_bfd, common between dbxread and coffread.
3690 * dbxread.c: Remove static symfile_bfd.
3691 * infcmd.c (do_registers_info): Add PRINT_REGISTER_HOOK, though
3693 * inftarg.c (child_detach): Pop the child_ops vector if the
3694 detach is successful.
3695 * remote-nindy.c (nindy_create_inferior): Don't push a new
3696 nindy_ops since nindy uses the same one for execution and memory
3698 * core.c (core_ops): Use child_attach and child_create_inferior
3699 rather than default attach and create_inferior functions.
3701 Handle floating point registers in core files.
3703 * sparc-xdep.c (fetch_core_registers): Rewrite for float support.
3704 * sun3-xdep.c (fetch_core_registers): Rewrite for float support.
3705 This version untested since BFD doesn't yet support sun3 core
3707 * hp300hpux-xdep.c: Rewrite fetch_core_registers to new calling
3708 conventions. Fix comments and style. This version has not
3709 been compiled yet, since we have no HP inhouse.
3710 * core.c (get_core_registers): Look for two sections, ".reg"
3711 and ".reg2", and pass both to fetch_core_registers sequentially.
3713 Revise directory path yet again.
3715 * source.c (forget_cached_source_info): Not static any more.
3716 (init_source_path): New default source path is "$cdir:$cwd".
3717 (dir_command): Handle variable arguments ($cdir, $cwd).
3718 (source_info): Print "Compilation directory" rather than
3719 "Originally compiled in" to remind people of $cdir.
3720 (openp): If the path contains $cwd, use current directory.
3721 (open_source_file): If compilation directory is known, replace
3722 first $cdir in path with the compilation directory.
3723 (print_source_lines): Even if we can't print the lines, set the
3724 current symtab and line for future commands like "info source" or
3725 "breakpoint". Also, error message now contains the file name,
3726 line number, and file access error message.
3727 (_initialize_source): Fix help text to describe changes.
3728 * main.c (cd_command): Forget cached source info when we chdir.
3729 * utils.c (strstr): Add simple implementation.
3731 Tue Mar 5 01:41:40 1991 John Gilmore (gnu at fowanton.cygnus.com)
3733 * coffread.c (read_one_sym, init_linetable, init_stringtab):
3734 Byte-swap COFF symbol tables if necessary when reading them in.
3735 Use complain() to replace error message in one spot. Needs
3736 corresponding change in bfd/coff-code.h to make some symbol
3737 swapping routines non-static.
3739 Mon Mar 4 00:53:40 1991 John Gilmore (gnu at cygint.cygnus.com)
3741 Merge changes from Eirik Fuller, for UTek.
3743 * defs.h (errno): Add declaration.
3744 * altos-xdep.c, arm-xdep.c, convex-xdep.c, gould-xdep.c,
3745 hp300hpux-xdep.c, infrun.c, inflow.c, infptrace.c, i386-tdep.c,
3746 i386-xdep.c, pyr-xdep.c, mips-xdep.c, remote-eb.c, remote-nindy.c,
3747 remote-vx.c, source.c, standalone.c, stuff.c, sun386-xdep.c,
3748 symmetry-tdep.c, symmetry-xdep.c, umax-xdep.c, utils.c: Eliminate
3749 declarations of errno.
3751 * remote-eb.c: Define B19200 and B38400 as EXTA and EXTB.
3753 * remote-vx.c: Include <sys/time.h> for UTek; Sun gets it via
3754 <rpc/rpc.h> and <rpc/types.h>.
3756 Sat Mar 2 15:47:55 1991 John Gilmore (gnu at cygint.cygnus.com)
3758 * i960-tdep.c (examine_prologue): Add new argument limit,
3759 which stops the scan at the end of the prologue, or at the PC.
3760 This fixes a problem where it walks down into the code for the
3761 user's statements if that code looks like function prologues.
3762 Mark Fox and I have been bouncing this code back and forth, making
3763 small changes to it. Callers changed to match.
3765 Tue Feb 26 01:47:07 1991 Cygnus John Gilmore (cygnus at yuba)
3767 Cleanup for gdb-3.94 release final:
3769 * Makefile.dist: Remove remote-vx.c, remote-nindy.c, and all
3770 the .c files from vx-share and nindy-share, from the various
3771 macros, since they are not found via ALLDEPFILES.
3772 (SFILES): Add tm-i960.h.
3773 (alldeps.mak rule): Break out ALLDEPFILES_MAINDIR and
3774 ALLDEPFILES_SUBDIR. List all the nindy and vxworks subdir files
3776 (TAGFILES_MAINDIR): Change ALLDEPFILES to ALLDEPFILES_MAINDIR.
3777 (gdb.tar.Z): Use ALLDEPFILES_SUBDIR as well as SFILES_SUBDIR.
3779 Mon Feb 25 16:02:35 1991 Cygnus John Gilmore (cygnus at oldman)
3781 * am29k-tdep.c: Add contribution line.
3782 (examine_prologue): Cache information about function prologues in
3783 the misc-function-vector to avoid lots of references over the
3784 serial line while examining instructions.
3786 * core.c (core_close): New function made from cleanup_core.
3788 * core.c, exec.c, inftarg.c, remote-eb.c, remote-nindy.c,
3789 remote-vx.c, remote.c, target.c, target.h,
3790 Update target_ops vector to add attach, close, and load entries.
3791 Use add_syms_addr_command, not add_file_addr_command, for
3792 add_file. Break out close routine from existing code.
3794 * dbxread.c (really_free_pendings): Don't free pending_blocks;
3795 they are in an obstack.
3796 (read_dbx_symtab): Relocate end_of_text_addr in the psymtab.
3798 (define_symbol): Add symbol type parameter; change callers;
3799 pass type parameter to DBX_PARM_SYMBOL_CLASS macro to allow
3800 it to influence the symbol class on the i960.
3801 (define_symbol): Swap LOC_CONST's into target byte order.
3803 * exec.c (exec_close): New function.
3804 (exec_file_command): Call it.
3806 * findvar.c (read_relative_register_raw_bytes): Doc byte order,
3807 Fix byte order of frame pointer.
3808 (read_var_value): Result of 0 if var's value can't be found,
3809 e.g. missing FRAME_ARGS_ADDRESS. Byte-swap LOC_CONST and
3810 LOC_LABEL values to target order. Add LOC_LOCAL_ARG.
3811 (locate_var_value): Use read_var_value and use its lazy address
3812 as the location of the var's value. Lint.
3814 * i960-pinsn.c (next_insn): Add routine from vxgdb for scanning
3817 * i960-tdep.c (arg_address, i960_frame_find_saved_regs): Remove
3818 obsolete Intel versions in favor of vxgdb versions.
3819 (check_host, byteswap, byteswap_val, reorder_val): Eliminate
3820 code dealing with byte order of values, which Intel did in host byte
3821 order rather than gdb-4's target byte order.
3822 (i960_frame_chain_valid): Move to nindy-tdep.c.
3823 (examine_prologue, skip_prologue, frame_find_saved_regs,
3824 frame_args_address, leafproc_return, saved_pc_after_call,
3825 pop_frame): Add vxgdb versions from Mark Fox.
3826 (examine_prologue, frame_struct_result_address): Add code
3827 to deal with the saved value of G13 (struct return address
3829 (frame_args_address): Modify Mark's version to prefer the
3830 saved value over the current value in the topmost frame.
3831 Cache result in the frame info to avoid performance hair in
3833 (print_fault): Add gdb960 code for printing faults.
3834 (_initialize_i960): Actually call check_host.
3836 * ieee-float.c (ieee_extended_to_double, ieee_double_to_extended):
3837 add stub routines. FIXME, these currently just return zero!
3839 * infcmd.c (program_info): Use PRINT_RANDOM_SIGNAL.
3840 (attach_command): Call target_attach, not target_open, now.
3842 * infrun.c (normal_stop): Make global, not static, for vx_attach.
3843 (child_attach): Rename from child_open.
3844 (wait_for_inferior): Use PRINT_RANDOM_SIGNAL. If stop_pc is zero,
3845 don't confuse it with a zero step_resume_break_address.
3847 * inftarg.c (child_detach): Eliminate inferior_pid test.
3848 (child_files_info): Clean up message a bit.
3849 (child_ops): Use child_attach, not child_open, to attach.
3851 * mem-break.c: #ifdef out the whole file if BREAKPOINT is not
3852 set (e.g. on VxWorks or NINDY). Move read_memory_nobpt from
3853 findvar.c to here, since it depends on the contents of the
3854 shadow_contents of breakpoints, but keep if #if 0 since it is
3857 * nindy-tdep.c: New file, contains nindy_frame_chain_valid, moved
3860 * printcmd.c (address_info): Handle LOC_LOCAL_ARG. Lint.
3861 (ptype_command, display_command): Eliminate have_inferior_p and
3862 have_core_file_p in favor of target_has_stack or
3863 target_has_execution.
3864 (print_frame_args): Handle LOC_LOCAL_ARG. Eliminate duplicate
3865 code for actually finding the values of arguments, though we still
3866 keep track of the maximum stack offset for use in printing unnamed
3867 arguments. Handle missing FRAME_ARGS_ADDRESS.
3869 * remote-nindy.c (i960_print_fault): Move to i960-tdep.c.
3870 (struct nindy_regs): Define registers passed to/from nindy.
3871 (nindy_fetch_registers, nindy_store-registers): Translate between
3872 nindy and GDB formats for the registers.
3873 (dcache_init): Statically allocate the cache, since it was being
3874 allocated by a malloc that was never freed anyway.
3875 (nindy_create_inferior): Error, not core dump, if no exec file.
3876 (nindy_before_main_loop): Use target_load, not target_add_file.
3878 * remote-vx.c (net_load): Specify large timeout for load
3879 requests. Allow user to break out with INTERRUPT.
3880 (net_break): Remove useless code, clean up. Change callers.
3881 (parse-args, skip_white_space, find_white_space): Clean up arg
3882 parsing to cope with quoted strings.
3883 (net_wait, net_quit): Never call error, just return status.
3884 (vx_read_register, vx_write_register): Cleanup status checking.
3885 #ifdef the code based on which CPU we are using (960 or 68k),
3886 FIXME, this should be completely general but it isn't yet.
3887 (vx_xfer_memory, vx_resume): Cleanup status checking.
3888 (vx_run_files_info): Improve message.
3889 (vx_load_command): Renamed from vx_add_file_command. Allow load
3891 (net_ptrace): Remove unused routine.
3892 (vx_wait): Adopt code from vxgdb960 to cope with broken
3893 connections to target machine and prompt to disconnect. Remove
3894 debug printouts. Map some EVENT_'s to SIGnals.
3895 (add_symbol_stub, vx_open): Print names of object files we found,
3896 and "ok" if we read their symbols OK. Clarify output in general.
3897 (vx_attach, vx_detach, vx_kill): Add these commands.
3898 (vx_convert_from_virtual, vx_convert_to_virtual): Simplify.
3899 (vx_run_ops): Turn off all_mem, to avoid spurious msg in the
3900 "info files" output, and create_inferior, since we already have
3903 * stack.c (frame_info): Replace Frame_unknown with 0.
3904 (print_frame_arg_vars): Handle LOC_LOCAL_ARG.
3905 (return_command): Pop until the PC matches as well as the FP,
3906 so it works even if the FP is shared with another function,
3907 as in "frameless" or "leaf" procedures.
3909 * symfile.c (load_command): renamed from add_file_target_command.
3910 (add_syms_addr_command): renamed from add_file_addr_command.
3911 (add_syms_command): Stub to call target_add_syms.
3912 (_initialize_symfile): Change command names and descriptions,
3913 add-file => add-syms, and load from alias to its own command.
3915 * target.c (kill_or_be_killed, maybe_kill_then_attach,
3916 maybe_kill_then_create_inferior): Default for attempts to start
3917 a process, if one is already running, is to ask about killing
3918 it and retry if yes.
3919 (upstack_create_inferior): #if-0 it, strata obsolete it.
3920 (push_target, unpush_target, pop_target): to_close() a target
3921 before unstacking it.
3922 (target_info): Renamed from target_files_info.
3923 (_initialize_targets): Rename "i files" as "i target", accessible
3926 * target.h: Improve comments about the target_ vectored routines.
3928 * tm-i960.h: Remove NINDY-specific stuff to tm-nindy960.h.
3929 Convert commenting style to standard GNU style.
3930 (DBX_PARM_SYMBOL_CLASS): allow LOC_LOCAL_ARG's to be recognized.
3931 (SKIP_PROLOGUE): No longer a no-op.
3932 (SAVED_PC_AFTER_CALL): Now handles leaf procedures.
3933 (*_REGNUM): Sort register numbers.
3934 (REGISTER_BYTES, REGISTER_BYTE, REGISTER_RAW_SIZE,
3935 MAX_REGISTER_RAW_SIZE, REGISTER_CONVERTIBLE,
3936 REGISTER_CONVERT_TO_VIRTUAL, REGISTER_CONVERT_TO_RAW): Float regs
3937 are now 10 byte extendeds, not 8 byte doubles.
3938 (FRAME_CHAIN_VALID): Make this config-dependent, since it differs
3939 for nindy versus vxworks targets. FIXME, this should possibly go
3940 in the target vector.
3941 (EXTRA_FRAME_INFO, INIT_EXTRA_FRAME_INFO): Cache both
3942 frame_saved_regs and arg pointer with each frame.
3943 (FRAMELESS_FUNCTION_INVOCATION): New leafproc support.
3944 (FRAME_ARGS_ADDRESS): Use cached result.
3945 (FRAME_ARGS_ADDRESS_CORRECT): New, avoids g14 guessing.
3946 (FRAME_FIND_SAVED_REGS): Change arg to subsidiary fn.
3947 (PRINT_RAMDON_SIGNAL): Call print_fault.
3948 (POP_FRAME): Now works.
3950 * tm-nindy960.h: Break this off tm-i960.h. NINDY-specific
3951 option parsing and startup; STACK_END_ADDR, FRAME_CHAIN_VALID,
3952 BREAKPOINT, and DECR_PC_AFTER_BREAK are here.
3953 (ADDITIONAL_OPTION_HANDLER): use target_load, not
3956 * tm-vxworks960.h: Break this off tm-i960.h. VxGDB specific
3957 startup; DECR_PC_AFTER_BREAK, and FRAME_CHAIN_VALID are here.
3959 * valarith.c (value_subscripted_rvalue): Avoid handling
3960 floats and doubles specially; it gave alignment errors. Lint.
3962 * valops.c (value_of_variable, value_of_this): Error if unknown
3965 * valprint.c (print_floating): Bcopy rather than pointer-deref,
3966 to avoid alignment problems.
3967 (value_print): Handle unknown value address.
3968 (cplus_val_print): Two args are ignored; remove them. Change caller.
3969 (val_print): Use unpack_long rather than pointer-deref.
3972 (unpack_long, unpack_double): Use bcopy rather than pointer-deref
3973 to avoid alignment problems.
3974 (value_being_returned): Error if return value unknown.
3975 (set_return_value): Add bogosity warning, FIXME. *
3977 * TODO: A woman's work is never done.
3979 * Makefile.dist: Distribute REMOTE_OBS into tconfig files.
3980 Separate INCLUDE_CFLAGS for use with lint. Add LINTFILES.
3981 Add ieee-float.o to OBS.
3982 * tconfig/{nindy960,vxworks68,vxworks960}: Include the desired
3983 REMOTE_OBS remote-interface files in the TDEPFILES and TM_FILE.
3984 * tconfig/i960: FIXME. Half-merge, produce warning if config'd.
3986 Changes to generalize the VxWorks RPC protocol slightly, to handle
3987 i960 as well as 68000.
3989 * vx-share/dbgRpcLib.h (VX_SOURCE_STEP): Add.
3990 * vx-share/reg.h: Produce i960 regs #ifdef I80960
3991 * vx-share/xdr_ptrace.c: Skip FPA registers if 960.
3992 * vx-share/xdr_rdb.h: Add SOURCE_STEP struct and xdr decl.
3993 * vx-share/xdr_rdb.c: Add xdr_SOURCE_STEP routine.
3994 * vx-share/xdr_regs.c: Add xdr_regs, xdr_fp_status, xdr_ext_fp
3995 for i960. Change xdr_vectors to xdr_opaques for 68k registers,
3996 so they will move in target byte order rather than network
3997 byte order (happens to be the same).
3999 Mon Feb 25 03:41:44 1991 John Gilmore (gnu at cygint.cygnus.com)
4001 * tm-convex.h (END_OF_TEXT_DEFAULT): Remove #if 0'd block.
4003 Sun Feb 24 00:55:53 1991 John Gilmore (gnu at cygint.cygnus.com)
4006 Add contribution lines to various files, showing where they
4009 * breakpoint.c (break_insn, check_break_insn_size,
4010 read_memory_nobpt): Remove to mem-break.c.
4012 * xm-*.h, param-no-tm.h, tm-29k.h, valprint.c: Change BYTE_ORDER to
4015 * tm-29k.h (STAB_REG_TO_REGNUM): Warn user if symbol table
4016 entry has bad register number. This change is not
4017 tested in this release, FIXME.
4019 * frame.h: Eliminate Frame_unknown in favor of a simple zero.
4022 * value.h: Force value's contents field to be aligned to hold
4023 at least a double or a long long (if supported). This avoids
4024 doing bcopy's in and out of the contents field.
4026 (step_1): Avoid coredump under obscure circumstances when we
4029 * symtab.h (misc_info): Add field to misc function vector for
4030 any kind of cached information the target code desires. AMD
4031 29000 uses this to avoid repeating examine_function_prologue's.
4033 * coffread.c: Lint. Remove static symfile, read_section_header.
4034 core.c (have_core_file_p): Lint: remove.
4035 expprint.c (print_subexp): Lint.
4036 infptrace.c, valops.c, valprint.c: lint.
4038 Roll in changes from vxgdb-5.0.1:
4040 * symtab.h: Comment byte order of each address class. Add
4041 LOC_LOCAL_ARG for frame-relative args (960).
4042 expread.y: Use LOC_LOCAL_ARG where LOC_ARG is used.
4043 symtab.c, symmisc.c: ditto.
4045 * infrun.c (init_wait_for_inferior): Clear stop_signal.
4047 * remote.c (remote_resume): Error if resume with a signal.
4049 * symfile.c (prim_record_misc_function): Clear misc_info.
4050 (fill_in_vptr_fieldno): Check stub type of arg.
4052 * valops.c (value_cast): Avoid looking up names of types whose
4053 name we don't know, to prevent coredump. Sun CC produces typedef
4054 rtx and the name of *rtx is zero...
4056 Mon Feb 18 21:16:25 1991 John Gilmore (gnu at cygint.cygnus.com)
4058 Roll in changes from final AMD 29000 port (Tiemann).
4060 tconfig/am29k: Add COFF_ENCAPSULATE and TARGET=TARGET_AM29K
4061 for ../include/a.out.encap.h. This might not work now that BFD
4062 is separately compiled. Instead, BFD support for encap will have
4063 to translate machine type 29k into the right COFF_MAGIC.
4065 * infcmd.c: Remove references to inferior_pid that aren't used
4066 in actual ptrace calls; use target_has_execution, etc.
4067 (have_inferior_p): Remove function.
4068 (program_info): Print target info rather than "process number";
4069 avoid gratuitous messages unless from_tty.
4070 (run_stack_dummy, finish_command): Set proceed_to_finish.
4071 infrun.c: Remove inferior_pid refs. Decl & init proceed_to_finish.
4072 main.c: Lint. Lose have_inferior_p().
4073 inferior.h (have_inferior_p): Remove, lint.
4074 (proceed_to_finish): Add flag to ask that all regs be saved
4075 by normal_stop, for the few commands that need it, speeding up
4076 serial I/O. Add comments to stop_registers.
4078 * remote-eb.c: Remove newline from breakpoint message we grep
4079 for. Never time out when running the user program.
4083 Wed Feb 13 15:34:40 1991 John Gilmore (gnu at cygint.cygnus.com)
4085 Roll in changes from vxgdb-5.0.1:
4087 * dbxread.c (read_dbx_symtab): If we encounter a "FORTRAN COMMON"
4088 symbol in its raw form, we are processing an unlinked ".o" file.
4089 See if the target environment has assigned it an address, using
4090 target_lookup_symbol (VxWorks does), and enter it into the symtab
4093 * tm-vxworks.h (FRAME_CHAIN, FRAME_CHAIN_VALID): Override usual
4094 68k versions for a simpler version that assumes zero FP at bottom.
4095 Fixes bug of truncated stack reports.
4097 * target.h (target_lookup_symbol): Define this routine's args
4098 and result, finally.
4100 * target.c (nosymbol): Default routine for target_lookup_symbol.
4101 (target_default): Default lookup_symbol and call_function too.
4102 (files_info): Only print has_all_memory warning if a non-dummy
4105 * remote-vx.c (vx_read_register, vx_convert_to_virtual,
4106 vx_convert_from_virtual): If target does not have floating point,
4107 zero register "values", and avoid doing cross-net conversions.
4108 (vx_lookup_symbol): Rename net_lookup_symbol, add to vectors.
4109 (vx_open): Rearrange code that attaches to target and reads
4110 symbols for all loaded modules, to work if some of the modules
4111 are not accessible. Add symbol_stub() and add_symbol_stub()
4112 as callbacks from catch_errors(). Allow connect attempt to be
4113 interrupted painlessly with ^C (FIXME, there are still some bugs
4114 if the interrupt happens during symbol reading.). Print
4115 final message with puts_filtered, since symbol messages are
4120 * main.c (catch_errors): Only print errstring if non-null.
4121 (command_loop): Avoid an ioctl per command to test ISATTY.
4123 * remote-vx.c (net_load): make static; avoid sophomoric msg.
4124 (vx_xfer_memory): Return correct result!
4125 (vx_files_info): Indicate whether target has float or not.
4126 (vx_lookup_symbol): Complain, not error, if target gone.
4127 (vx_open): Print "Connected" msg before disabling immediate-quit.
4128 [FIXME: lookup_symbol and vx_open changes need testing.]
4130 target.c, remote-eb.c, inftarg.c, am29k-opcode.h, target.h,
4131 tm-29k.h, tmm-vxworks68.h, symfile.c, gdb-int.texinfo: Add
4132 contributor lines and update copyrights to 1991.
4134 Changes from an attempted H-PUX host port:
4136 * infptrace.c (PT_ATTACH, PT_DETACH): Handle HP/UX, which
4137 defines PT_ATTACH and PT_DETACH but not PT_KILL.
4138 * remote-eb.c (eb_open): Misplaced endif kills sysv H/PUX.
4139 * remote-vx.c: include <sys/time.h> for HPUX.
4140 * hp300hpux-xdep.c (fetch_core_registers): Rewrite old
4141 "core_file_command" routine to BFD regime. May not work yet.
4143 Attempted port of "gdb-3.4 Van Jacobson xgdb" to modern gdb.
4145 * xgdb.c: Replace X10 version with some VJ version.
4146 (FIXME: Its copyright assignment is not on record.)
4147 * xgdb.c: Update include files to X11R4 (Xaw crud).
4148 (xgdb_display_source, create_text_widget): fix call to
4149 get_filename_and_charpos. Rewack source window stuff for X11R4
4150 (gleaned from include files, and "nm's" of binary libraries, since
4151 I had no doc available).
4152 (append_selection, append_selection_word): Disable with FIXME
4153 since R4 changed interface here.
4154 (create_buttons): Add back the old set of buttons.
4155 (xgdb_create_window): Fix call to XtInitialize (&argc not argc).
4157 * Makefile.dist (xgdb, xgdb-init.c): Update for X11R4 on Suns.
4158 Roll VERSION to 3.94 (not yet final though).
4160 Sat Feb 9 09:46:25 1991 John Gilmore (gnu at cygint.cygnus.com)
4162 * obstack.h (obstack_ptr_grow, obstack_ptr_grow_fast,
4163 obstack_int_grow, obstack_int_grow_fast): Eliminate
4164 cast on left of assignment, which gives MIPS cc fits and is
4167 * sparc-pinsn.c (print_insn): Eliminate 'set' test, subsumed by
4168 F_ALIAS. Use printf, not fprintf, when not passing a file
4170 (compare_opcodes): Check that identical instructions have
4171 identical opcodes, complain otherwise.
4173 * sparc-opcode.h (st %fsr): Fix opcode "lose" mask. This
4174 was reported by Roland McGrath.
4175 (unimp): Only match if exactly zero instruction. (Roland)
4176 (branches and traps): Generate all variations of these
4177 instructions with macros, based on a single call that defines
4178 each condition name and its binary representation.
4179 (set): Turn on alias bit, to avoid test in sparc-pinsn.c.
4181 * valprint.c (val_print_fields): Take, and use, format parameter.
4182 This means that "p/x struct" again prints the elements in the
4183 desired format. Changed callers.
4185 * stack.c (frame_info): Use filtered output, and indicate wrap
4186 points. Remove kludgy formatting designed to avoid line wrap.
4188 * utils.c (wrap_here): If the line is already full (because
4189 we had printed a long indent or long wrapped string), do an
4190 immediate newline-and-indent.
4192 * m68k-pinsn.c (print_insn_arg): Bugfix from
4193 ntmtv!thompson@ames.arc.nasa.gov (Mike Thompson): 'bkpt #0'
4194 instruction is incorrectly disassembled as bkpt #8.
4196 * dbxread.c (end_psymtab): Bugfix from Peter Schauer
4197 <pesrem@regent.e-technik.tu-muenchen.de>: If you want to set a
4198 breakpoint in a *.y file gdb will say Reading in symbols for *.y...
4199 and then will dump core (sometimes). I traced it back to an
4200 uninitialized symfile_name in psymtab_to_symtab.
4201 (const_vol_complaint): Add quotes to message.
4202 (define_symbol): Only believe line number if gcc_compiled.
4203 Avoid allocating symbol if we will not return it.
4205 Add target strata support so that newly established targets go
4206 into their right place in the target stack (e.g. a new exec file
4207 doesn't wipe out the ability to access the running process).
4209 * target.h, core.c, exec.c, inftarg.c, remote-eb.c,
4210 remote-nindy.c, remote-vx.c, remote.c, target.c: Add to_stratum
4211 and initialize it properly in all the targets.
4213 * target.h: Document strata. Change return type of push_target.
4215 * target.c (nomemory): new function for dummy memory access.
4216 (tcomplain): Rename complain, now also used in symfile.c.
4217 (push_target): Push targets within strata. New return value shows
4218 whether new target is on top of stack or not. Always keep dummy
4220 (target_files_info): Ignore dummy target.
4222 * core.c (core_open): Warn user, and skip accessing file, if the
4223 core target is not the topmost target in the stack.
4224 * remote-nindy.c (nindy_create_inferior): Avoid unpush_target, now
4227 * remote-vx.c: Remove vx_prepare_to_store from vxworks memory
4228 target_ops, it doesn't belong there since we have no regs there.
4229 Change name of target from machine => memory to clarify.
4231 Thu Feb 7 16:32:09 1991 John Gilmore (gnu at spiff.cygnus.com)
4233 * Freeze version 3.93 for release.
4235 * Makefile.dist: Handle vx-share and nindy-share subdirs
4236 properly when building gdb.tar.Z.
4238 * symtab.c: lint; add no_symtab_msg to consolidate the messages
4239 printed in various places, so I could change just one copy.
4241 * dbxread.c, coffread.c: Change references to bfd->iostream
4242 to cast to FILE *, now that BFD avoids needing types defined
4243 in other header files.
4245 Tue Feb 5 21:39:35 1991 John Gilmore (gnu at cygint.cygnus.com)
4247 * command.c, dbxread.c, expprint.c, infcmd.c, infptrace.c,
4248 infrun.c, printcmd.c, remote-nindy.c, source.c, sparc-tdep.c,
4249 sparc-xdep.c, symfile.h, symmisc.c, utils.c, valprint.c: Lint
4250 (actually gcc -Wall).
4252 * dbxread.c: Remove first_global_sym, last_global_sym, since
4253 they are never referenced.
4255 * defs.h (baud_rate): Declare.
4256 main.c: Define it, and add the -b option to set it.
4258 * gdb-int.texinfo: Add text on how to define a new host or target
4259 architecture, prompted by Per Bothner's questions about MIPS
4262 * gdb.texinfo: Document "complaints". Change doc of -q since
4263 gdb no longer prints the copyright and blurb if you specify a file
4264 name to be debugged (just like Emacs). Add doc for Nindy-specific
4265 command line flags for specifying target serial port and such.
4266 Update copyright to 1991.
4268 * gdbcore.h: Remove a large mass of now-useless crud, since BFD
4269 has taken over for us the job of ripping up executable files. The
4270 crud caused Per Bothner's port to not compile.
4272 * infrun.c (normal_stop): Avoid printing "Program exited
4273 normally" if we are in batch mode. This allows a GDB which
4274 executes a program on a target system, to behave like a Unix
4275 command (input from stdin, output to stdout, no extraneous
4278 * main.c (main): Allow additional machine-dependent command line
4279 options to be specified with the ADDITIONAL_OPTIONS,
4280 ADDITIONAL_OPTION_CASES, ADDITIONAL_OPTION_HELP, and
4281 ADDITIONAL_OPTION_HANDLER macros. Also allow machine-dependent
4282 processing to occur just before the main loop with
4283 BEFORE_MAIN_LOOP_HOOK.
4284 (main): If a "core file" argument is specified, and it is not a
4285 core file, try it as a process ID to attach.
4286 (symbol_completion_function): Attempt to cope with
4287 "show screen-" TAB, not very successfully. This needs more work,
4289 (batch_file): New function, returns whether we are reading
4290 commands from an interactive tty on stdin, or from somewhere else.
4291 Called by normal_stop since it doesn't get from_tty passed down
4292 to it like many commands do.
4294 * remote-nindy.c: Handle command line options for nindy
4296 (nindy_before_main_loop): Prompt user for tty name if they
4297 don't specify it before getting to the interactive command loop.
4299 * tm-i960.c: Add ADDITIONAL_OPTIONS, etc, to handle -O, -brk,
4300 and -r command line options. Also add hook before main loop
4301 to make it easy to specify a tty.
4303 * TODO: More things to do, one done.
4305 Mon Feb 4 23:57:39 1991 John Gilmore and Mike Tiemann (at cygint.cygnus.com)
4307 * dbxread.c: Make complaint() calls pass pointer, not struct.
4308 Add complaints about badly formatted C++ type information
4309 (const/volatile indicator, and parse errors resulting in
4310 error_type). Fix C++ virtual member fn comment.
4311 (read_struct_type): Avoid bumping pointer if we got a parse
4312 error; this prevents our walking beyond the end of a string.
4313 Terminate loop on null char as well as semicolon.
4314 (process_one_symbol): Fix the LBRAC fix so that it uses the
4315 last previous SLINE, FUN, or SO record's PC address. C++ debug
4316 symbols did not have SLINE records in a useful order compared
4317 to the LBRAC records.
4318 (define_symbol): Handle "catch" records.
4320 * symtab.c (check_stub_type): Added new complain
4321 `stub_noname_complain' and added a consistency check to
4322 keep the debugger from crashing when finishing from an
4323 exception frame. A real fix will be needed later.
4325 Sat Feb 2 10:43:05 1991 John Gilmore (gnu at cygint.cygnus.com)
4327 * infcmd.c (attach_command): Make global.
4329 * Makefile.dist (REMOTE_OBS): Make these compile by default,
4330 but make them easy to comment out. Perhaps later they should
4331 be enabled by what CPU you configure for? FIXME.
4332 (VERSION): Roll to 3.93.
4333 (pinsn.o): Remove rule for obsolete file.
4334 (dbxread.o,coffread.o,mipsread.o): Use ${srcdir} explicitly.
4336 Run down a problem that manifested by printing the wrong function
4337 name in stack traces of read_ofile_symtab. Turned out that the
4338 problem was the SunOS 4.1.1 (and previous) C compiler outputs
4339 the LBRAC symbol with an address in the *data* segment, which
4340 blew our binary search through the blocks.
4342 * dbxread.c: Use the complain() facility consistently to bitch
4343 about problems in the symbol file we are reading.
4344 (finish_block): Add code to check the nesting of the blocks;
4345 complain and Procrust them to fit if wrong.
4346 (make_blockvector): Check the order of the blocks, complain
4347 [but don't cope] if wrong.
4348 (process_one_symbol): ifndef SUN_FIXED_LBRAC_BUG, check LBRAC
4349 symbols to be sure their PC value is greater than the last SLINE
4350 (line number) symbol we've seen, complaining and adopting the
4351 SLINE PC value if wrong.
4353 * symfile.h (struct complaint, complaint_root, complain,
4354 clear_complaints): Add.
4355 * symfile.c (complain, complaint_root, clear_complaints): Add
4356 facility to deal with non-fatal complaints and to regularize their
4358 (symbol_file_add): Clear complaint counters to allow new complaints.
4359 (initialize_symfile): Add 'set complaints' and 'show complaints'.
4361 * dbxread.c (dbx_symfile_read): Remember the address and size
4362 of the string table for the main symbol file, so we won't read it
4364 (dbx_psymtab_to_symtab): Fix the check for main symbol file,
4365 to avoid reading the string table yet again. Lint.
4366 (throughout): Improve filtered output, including word wrap.
4367 (read_range_type): Improve Bothner's fix to handle other types too.
4369 * utils.c: Improve line wrap implementation. Handle unlimited
4370 width by making chars_per_line unsigned.
4371 (puts_filtered): New, easy, function.
4373 * defs.h (puts_filtered): add.
4375 * mipsread.c (compare_symbols, sort_symtab): Remove these fns,
4376 call the identical sort_symtab_syms() in symfile.c instead.
4378 * expread.y: Suggest the `file' command rather than `symbol-file'.
4380 * command.h (enum var_types): Add zinteger for seroable
4382 * command.c (do_setshow_command): Handle var_zinteger. Restructure
4383 nested if's into a switch.
4385 * breakpoint.c (bpstat_print): If bpstat "print" flag is not set,
4386 we did not stop because of a breakpoint (it must have been for
4387 some other reason, like a "stepi"), so don't print anything.
4389 * symtab.c: Include <sys/types.h> all the time. Now that BFD
4390 doesn't include <sys/types.h>, old SunOS's require it for
4393 Sat Feb 2 10:39:15 1991 Per Bothner (bothner@cs.wisc.edu)
4395 A test port of gdb-3.92.6 to the Sony NEWS.
4398 Don't normally link in remote- or vx stuff.
4399 Some of it doesn't compile, and it wastes space for 99% of the users.
4400 Remove reference to no-longer-used HAVE_VPRINTF.
4401 Fixed BFD_DEP typo to BFD_DIR.
4403 Fix cast in arg to bfd_h_getlong.
4404 Make char *prefix be const.
4405 Fix how certain range types are mapped into builtin unsigned int types.
4407 Remove 2 #includes. They cause errors (on Sony, at least),
4408 and aren't needed (they wern't in earlier versions).
4410 print_address_symbolic should never demangle labels
4411 (since it prints *assembler-level* labels).
4413 [This was superseded by the change to printcmd below.]
4416 Add some "volatile" return types to avoid warnings.
4417 If MISSING_VPRINTF add vprintf function and not just macro
4418 (since vprintf is used in printcmd.c).
4420 Unless __GNUC__, use obstack_grow instead of obstack_ptr_grow.
4421 (The latter isn't grokked by some PCC-based compilers.)
4423 [This change is in abeyance, we prefer to fix obstack_ptr_grow.]
4425 Make chunk size of dont_print_obstack 32*4 instead of default 4096.
4426 * nindy-share/coffstrip.c
4427 Added some forward declarations (otherwise, gcc complains
4428 about implicit extern redefined as static).
4430 Sun Jan 20 02:38:19 1991 John Gilmore (gnu at cygint.cygnus.com)
4432 Changes inspired by Per Bothner:
4433 * printcmd.c (print_address_symbolic): Take additional parameter
4434 specifying whether to demangle.
4435 (print_address): Pass in asm_demangle to control demangling.
4436 (print_address_demangle): New fn, takes explicit arg to control
4438 * utils.c: Add new vars demangle and asm_demangle, and let them
4440 (fputs_demangled): If !demangle, just print the argument.
4441 (fprint_symbol): If !demangle, just print raw symbol.
4442 * valprint.c (val_print): Call print_address_demangle rather than
4443 print_address, to cause demangling to depend on the global
4444 rather than assembler-level demangling setting.
4445 * WHATS.NEW, gdb.texinfo: Document.
4447 * main.c (show_command): Show all settings if no arg.
4448 (initialize_main): Make "info set" the same as naked "show".
4449 * command.c (cmd_show_list): Handle prefix commands in the
4450 list, and print the name of the setting as well as its English
4451 description and value.
4453 Allow gdb functions to specify where a line should wrap if it
4454 exceeds the size of a terminal line. Use it to make the output
4456 * utils.c (set_screen_width_command): New fn, mallocs a buffer
4457 of the right size when screen width changes.
4458 (set_screensize_command, screensize_info): Remove #if 0'd fns.
4459 (wrap_here): New fn, indicates a point in the output where we
4460 should wrap the line rather than just letting it overflow at a
4462 (fputs_filtered): Implement wrapping.
4463 (n_spaces): New fn, returns a pointer to N spaces.
4464 (print_spaces_filtered): Use n_spaces.
4465 * defs.h (n_spaces): Declare.
4466 * stack.c (print_frame_info): Wrap with 4-space indent after
4467 fn name and before filename and line number.
4468 * printcmd.c (print_frame_args): Wrap with 4-space indent
4469 before each argument name is printed.
4470 * valprint.c (value_print): Wrap with no indentation before
4472 (val_print_fields): Wrap with indentation relative to nesting
4473 level before each field name.
4474 (val_print): Wrap with nesting indentation before array elements.
4475 * command.c (do_setshow_command): Avoid extra newlines,
4476 wrap with 4-space indent around values printed, end with period.
4477 * WHATS.NEW, gdb.texinfo, gdb-int.texinfo: Document.
4479 * breakpoint.c (breakpoint_1): Implement addressprint for
4480 "info breakpoints" display. Change file name and line number
4481 format to " at file:nnn" rather than " (file line nnn)".
4482 * gdb.texinfo: Document.
4485 Fri Jan 18 07:21:25 1991 John Gilmore (gnu at cygint.cygnus.com)
4487 Frozen for gdb-3.92.6 release.
4489 README, WHATS.NEW: Update for 3.92.6 release.
4491 tconfig/{altos, i386v, i386v32, m88k, umax}: Eliminate
4492 coffread.o from configs since it is now built by default.
4493 tconfig/{3b1, altosgas, arm, convex, hp300bsd, hp300hpux,
4494 i386v-g, i386v32-g, isi, merlin, news, news1000, np1, pn,
4495 pyramid, symmetry, vax, vxworks68}: Eliminate dbxread.o
4496 from configs since it is now built by default.
4498 Makefile.dist: Update for release 3.92.6. Handle files that
4499 have been moved to ../include, ../getopt, or ../bfd. Add
4500 saber.suppress and tests directory. Add config.status to
4501 the release (it will say "none").
4503 coredep.c: Minor formatting fixes.
4505 These changes were made in early December but only checked in now:
4506 * nindy-share/Onindy.c, nindy-share/coffstrip.c,
4507 nindy-share/nindy.c: lint
4508 * nindy-share/nindy.c (ninStopWhy): Don't byteswap the
4509 register values coming back from the target; we store values
4510 in target byte order everywhere.
4512 Wed Jan 16 19:01:37 1991 John Gilmore (gnu at cygint.cygnus.com)
4514 * am29k-opcode.h, am29k-pinsn.c: Add 29050 opcodes.
4516 * valprint.c (cplus_val_print, val_print_fields): New functions,
4517 which print C++ objects. They conspire to avoid printing a
4518 virtual base class more than once, following all the twists and
4519 turns of C++ virtual base rules.
4520 (val_print): Call the above rather than do it by hand.
4522 * symfile.c (symbol_file_add): Only reset symfile_mtime for main
4523 symbol file, not for added files like shared libs. This really
4524 needs to be generalized to a timestamp per file.
4526 * core.c (cleanup_core): Avoid coredump if no core file.
4528 * config.gdb: Accept -host or -target in place of +host or
4531 * coffread.c (find_linenos): Avoid desupported BFD interface
4532 to line numbers. We still read them manually rather than using
4533 BFD's "generic" features.
4535 * gdbrc.tex, threecol.tex: Add GDB reference card and its
4537 Makefile.dist: Add refcard to OTHERS list for creating tar files.
4539 * Makefile.dist: Eliminate use of $< in explicit targets.
4541 * readline/Makefile: Use $< rather than $*.c, which does not
4542 include the VPATH in GNU Make.
4544 * tconfig/i960-bout, tconfig/i960-coff: These are identical
4545 copies of tconfig/i960, added for global configuration
4546 compatability. All i960 versions can read both coff and b.out.
4548 * tm-88k.h: Fix multiline macro that lacked \'s. Remove
4549 COFF_FORMAT and COFF_CHECK_X_ZEROES since these are now handled
4552 * TODO: Think of more things to do.
4554 Wed Jan 2 19:09:29 1991 John Gilmore (gnu at spiff.cygnus.com)
4556 tconfig/{am29k,i960,sun2*,sun3*,sun4*}: Eliminate config
4557 of sdb versus dbx debug symbols. Add kludge for 68881 80-bit to
4558 64-bit float conversion.
4560 tconfig/sun4, tconfig/sun3, xconfig/sun4, xconfig/sun3: Make
4561 equivalent to sun?os4 so global config works.
4563 Wed Jan 2 18:20:51 1991 John Gilmore (gnu at spiff.cygnus.com)
4565 Fix from Eberhard Mattes <mattes@azu.informatik.uni-stuttgart.de>
4567 * main.c: Only declare linesize once; declare pagesize not at
4568 all, since it is never used.
4569 (main): Clear newly allocated line before it is used.
4571 Fri Dec 28 00:13:42 1990 John Gilmore (gnu at cygint)
4573 Further stabilization for the Intel 960.
4575 * Makefile.dist: Parameterize the location of the "include"
4576 and "bfd" directories, as well as "getopt". Add symfile.c.
4577 Link in both dbxread and coffread. Fix up "make depend" to
4578 rewack the locations of include, bfd, and getopt in its output.
4580 * README: Document moving include files, improve some of
4583 * coffread.c: Move common code out to symfile.c. Change
4584 symbol_file_command style interface to use new *_symfile_init
4585 and *_symfile_read interface under BFD. Use BFD internal
4586 info to locate line table, symbols, etc.
4588 * core.c (core_fetch_registers): Rename to get_core_registers
4589 to avoid confusion with fetch_core_registers.
4590 (register_addr): Move to coredep.c, which is already machine
4591 dependent. This leaves core.c pretty clean of dependencies.
4593 * coredep.c (register_addr): Accept this routine from core.c.
4595 * dbxread.c: Move common code (with coffread.c, etc) into new
4596 symfile.c. Each psymtab now contains a pointer to the
4597 format-dependent function that knows how to read it in. Make
4599 (dbx_psymtab_to_symtab): Renamed from psymtab_to_symtab_2.
4600 (process_one_symbol): Add code to complain about a "compiler bug
4601 we muzzle here", if we actually see it.
4603 * eval.c (evaluate_subexp): Insert missing "break" statements
4604 in code that determines whether a variable is an lvalue in
4605 memory, register, or whatever. I detected this via a compiler
4606 bug in which it *almost* mashed out the whole switch statement.
4608 * gdb-int.texinfo: Add minor sections on configuring gdb for
4609 release, and about the README file.
4611 * infcmd.c (registers_info): Fix formatting somewhat. Still
4612 not as pretty as before, but it handles byte swapping.
4614 * remote-nindy.c: If data cache routines are interrupted while
4615 waiting for the remote end, be sure that any uninitialized cache
4616 blocks are on the free list, not on the valid list!
4618 * symfile.h: Flesh out this header file with all the various
4619 routines and variables that have been merged in from dbxread.c
4620 coffread.c, and symtab.c to symfile.c.
4622 * symfile.c: New file, containing code common to dbxread.c,
4623 coffread.c, and some code from symtab.c. All generic code for
4624 reading symbol files should be in here now.
4625 (unrecord_misc_function): Remove unused function.
4627 * symtab.h: Remove file-reading things to symfile.h.
4629 * symtab.c: Remove file-reading things to symfile.c.
4631 * tm-i960.h: Fix FRAME_CHAIN types; define PRINT_RANDOM_SIGNAL
4632 to decode i960 fault types.
4634 * target.h, remote.c, remote-eb.c, remote-vx.c, remote-nindy.c,
4635 target.c: Change type of the "resume" function from int to void,
4636 since its result was never used.
4638 Sat Dec 22 02:51:40 1990 John Gilmore (gnu at cygint)
4640 * main.c: Replace "stupid" with "caution"; you now "set caution
4643 * printcmd.c (print_scalar_formatted): Fix typo in 'g' format
4645 * infcmd.c (do_registers_info): Call val_print to deal with the
4646 byte order of the registers being printed. FIXME, this makes
4647 the formatting of the output uglier.
4649 * infcmd.c (wait_for_inferior): If PRINT_RANDOM_SIGNAL is
4650 defined, call it for signals the debugger doesn't itself use.
4651 The i960 uses this for more detailed fault information.
4653 * remote.c (remote_open): If arg is null, print help rather than
4656 * sparc-xdep.c (register_valid): Avoid declaring size, since
4657 various modules will think of various sizes depending on the
4658 architecture of their tm-file. FIXME, we need protection against
4659 actually entering one of those modules, which would clobber
4660 storage if not for the target architecture compiled into gdb.
4662 * stack.c (up_command, down_command): Always print the frame
4664 (up_silently_command, down_silently_command): New commands
4667 * i960-pinsn.c (reg), i960-tdep.c: Lint.
4669 * i960-tdep.c (i960_frame_chain_valid): Lookup_symbol now takes
4670 more parameters than it used to.
4672 * findvar.c (registers): Increase slop to 256 bytes, which should
4673 protect us against even most RISC machines with large register
4675 (locate_var_value): Move declaration inside related ifdef.
4677 * remote-nindy.c (): Use TIOCSETN rather than TIOCSETP
4678 throughout, to avoid throwing away buffered input from the board.
4679 (nindy_wait): Supply_register takes addr_of_value, not value.
4680 (i960_print_fault): Renamed from i80960_fault.
4681 (nindy_fetch_registers): Avoid have_regs stuff, just get them.
4682 (nindy_store_registers): Avoid regs_changed stuff, just stuff
4684 (nindy_create_inferior): Don't bother to write PC_REGNUM since
4685 we can set the PC in the call to proceed(). Unpush nindy_ops
4686 before pushing it on top, to avoid message to user. Eliminate
4687 commentary from Unix machines that just misleads here.
4688 (reset_command): Fix error message to suggest target command.
4690 Wed Dec 19 11:03:56 1990 John Gilmore (gnu at cygint)
4692 Release 3.92.5 as frozen.
4694 Stabilize the merged release...with help from lint, Saber C,
4697 Everywhere: Add include files needed to declare return types
4698 of functions called.
4700 * gdb.texinfo: Roland Pesch is documenting gdb, glory be!
4702 * breakpoint.h: Add undeclared breakpoint functions, and some
4703 functions for display handling since I couldn't think of a better
4706 * breakpoint.c (insert_breakpoints): Make code for disabling
4707 shared library bkpts more likely to work. It's used when we
4708 rerun a program and stop before the shared library has been
4710 (breakpoint_cond_eval, bpstat_stop_status): Pass arg as int,
4711 cast from pointer, so it squeezes through catch_errors.
4712 (bpstat_stop_status): Fix logic broken some time ago. We now
4713 always create a bpstat if the stop address matches a breakpoint,
4714 even if we don't stop there -- just like the old code used to do
4715 before I got my fingers into it (sigh).
4716 (breakpoint_1): Print "ignore count" after "stop only if"
4717 condition, since that's how it actually works.
4718 (mention): Handle watchpoints as well as breakpoints.
4719 (watch_command): use set_raw_breakpoint and mention to do most
4720 of the work (and initialize all the fields!). Only pass one
4721 arg to parse_c_expression, since that's all it takes.
4723 * command.c (not_just_help_class_command): Rename arg to args
4724 since we ignore "unused argument" warnings on vars named "args".
4725 inflow.c (child_terminal_info): ditto.
4726 infptrace.c (kill_inferior): ditto
4727 main.c (catch_errors, version_info, quit_command, pwd_command,
4728 source_command, dump_me_command, editing_info,
4729 set_history_size_command, set_history, show_history,
4731 stack.c (locals_info): ditto
4732 target.c (target_files_info): ditto
4733 valprint.c (set_input_radix, set_output_radix): ditto
4735 * core.c: Remove old variables for handling core and exec file
4736 sections (data_start, data_end, stack_start, stack_end,
4737 reg_stack_start, reg_stack_end, reg_stack_offset, text_start,
4738 text_end, exec_data_start, exec_data_end, text_offset,
4739 exec_data_offset, data_offset, stack_offset). They're
4740 superseded the more general build_section_table and
4742 (get_exec_file): Mention the `file' command.
4743 (read_memory_check): Rename to memory_error, and only call it
4744 in the case of an actual error.
4745 (read_memory, write_memory): call memory_error.
4746 (core_fetch_registers): Register section name is ".reg".
4748 coredep.c: Remove a bunch of crud now that all this file does
4749 is pull the registers out of a core file.
4750 (fetch_core_registers): Rewrite to actually work, I hope.
4752 dbxread.c: Use a.out.gnu.h, not system a.out, now.
4753 Replace index() with strchr(). Remove all the pre-BFD macro
4754 definitions for accessing the symbol file.
4755 (struct dbx_symfile_info): Encapsulate the information that
4756 dbx_symfile_init needs to pass to dbx_symfile_read in this
4759 (dbx_new_init, dbx_symfile_init, dbx_symfile_read,
4760 dbx_symfile_discard): Rearrange symbol file reading to divide
4761 the format-specific part from the format-independent part,
4762 leaving the format-independent part such as file name expansion
4763 and opening in symtab.c. This replaces
4764 partial_symbol_file_open and partial_symbol_file_read.
4765 Symbol_file_read, add_file, add_file_target_command,
4766 add_file_addr_command move to symtab.c. Pass an explicit
4767 "mainline" flag for when reading the main symbol table, rather
4768 than relying on the offset address to be zero or nonzero.
4770 (dbx_symfile_read): Don't allow void *'s to be printed as
4772 (SWAP_SYMBOL): Use bfd routines to byte-swap the symbols.
4773 (ADD_PSYMBOL_TO_LIST): Make the "function call rather than
4774 macro" debug version really work.
4775 (read_dbx_symtab): Remove unref'd parameter inclink.
4776 Avoid swapping N_SLINE symbols, for speed.
4777 Merge N_TEXT!N_EXT case with the other external symbol
4778 definitions' case. Add comments.
4779 (start_psymtab): Allocate the symfile name in the psymtab on
4780 the psymbol_obstack, rather than using the caller's storage.
4781 (end_psymtab): Only allocate a dependencies list if there are
4783 (psymtab_to_symtab_2): Use BFD when reopening file to read
4784 its symbols for real.
4785 (read_struct_type): Add FIXME comments where it needs work
4787 (read_huge_number): Add FIXME about overflows.
4788 (read_range_type): Add FIXME about comparing a long to 1<<32.
4790 * coffread.c: Minor changes to move things closer to the new
4791 regime with symtab.c and dbxread.c Major work is still needed
4794 * exec.c (exec_file_command): Remove old variables (see core.c
4796 (xfer_memory): If memory transfer is right at the end of a
4797 section, don't lose.
4799 * findvar.c (get_saved_register): If value is in a real
4800 register, LVAL is lval_register, not lval_memory.
4802 frame.h: Declare print_sel_frame and record_selected_frame.
4804 gdb-int.texinfo: New file, for GDB internals documentation.
4805 Very simple, unformatted doc of cleanups is there for now.
4807 gdbcore.h: Remove obsolete variables that described a.out
4808 section addresses and offsets. (See core.c above.)
4809 Declare fetch_core_registers and registers_fetched.
4811 getopt.c: Declare char *alloca(); even on SPARC.
4813 infcmd.c (run_command): Call target_kill rather than
4815 (step_command, next_command, stepi_command, nexti_command):
4816 Declare from_tty parameter even though we don't use it.
4817 (run_stack_dummy): argument BUFFER is a char array, not
4818 a pointer to REGISTER_TYPE.
4819 (finish_command): using_struct_return needed a value *,
4820 not a struct symbol *.
4822 * infptrace.c (child_xfer_memory): To avoid dependency on
4823 where sections are in memory, try PT_WRITE_D and if that fails,
4824 try PT_WRITE_I. Most Unixes don't care which you use.
4826 * infrun.c (step_resume_break_shadow): Change to array to
4827 match other breakpoint shadow storage.
4828 (clear_proceed_status): Pass address of bpstat to
4829 bpstat_clear, not the bpstat itself.
4830 (child_create_inferior): FIXME comment about if the child
4832 (start_inferior): Remove old function.
4833 (child_open): Use target_kill rather than kill_inferior.
4834 (wait_for_inferior): Ditto.
4835 (insert_step_breakpoint, remote_step_breakpoint): Use
4836 new step_resume_break_shadow.
4838 * inftarg.c (child_wait): If all child processes die,
4839 pretend that the one being waited for exited with signal 42.
4841 * main.c (command_line_input): When scanning for comments,
4842 don't coredump on unclosed quotes.
4843 (quit_command): Use target_kill rther than kill_inferior.
4844 (_initialize_main): Rename class_user from "user" to
4847 * printcmd.c (print_command_1): Initialize "fmt" if no format
4848 is specified by the user.
4849 (print_frame_args): Only add to args_printed if we are
4850 actually fetching args from the stack (avoiding undefined
4852 (_initialize_printcmd): Remove bogus \{ from string.
4854 * remote-eb.c (eb_open): Avoid coredump on no argument.
4856 * remote-nindy.c: Bring out of Intel environment into new
4857 target environment. Remove all conditional compilation on
4858 I80960. Massive hacking throughout.
4859 (nindy_xfer_inferior_memory): New routine stolen from
4861 (nindy_create_inferior): New routine pieced together, probably
4862 not quite working yet.
4863 (nindy_ops): New target_ops struct for nindy.
4865 * remote-vx.c: Use write_memory rather than target_write_memory
4866 to get error checking.
4867 (vx_add_file_command, vx_open): Use symbol_file_add rather than
4869 (vx_create_inferior): Use target_terminal_ours...
4871 * signame.c (_initialize_signame): Always initialize, since
4872 we need the table for things other than psignal.
4874 * solib.c (solib_add): Use symbol_file_add, not add_file.
4875 (solib_address): Return boolean result rather than struct
4876 pointer which nobody else knows the type of.
4878 * sparc-tdep.c, valops.c: Use write_memory rather than
4879 target_write_memory, to get error checking.
4881 * stack.c (locals_info, catch_info, args_info,
4882 get_selected_block, frame_command, up_command): Use
4883 target_has_stack, rather than have_inferior_p or
4886 * sun3-xdep.c (fetch_core_registers): Rewrite for new BFD regime.
4888 * symfile.h: New file, defining the interface between the
4889 generic and object-file-specific symbol reading code.
4891 * symtab.c: Move generic symbol-reading interface to symtab.c,
4892 from dbxread.c, coffread.c, mipsread.c, etc. Add symtab_fns
4893 table to map BFD targets to symbol-reading modules in GDB.
4894 Change index to strchr.
4895 (lookup_struct_elt_type): Use error() rather than hand-made
4896 simulations thereof.
4897 (lookup_partial_symbol): Speedup slightly when length == 0.
4898 (symbol_file_add): New function.
4899 (symbol_file_command): Call it.
4900 (symfile_open, symfile_init): New function.
4901 (add_file_target_command, add_file_addr_command): moved from
4904 * target.c (target_command): use target_kill.
4906 * target.h (target_files_info): Don't declare, never called
4909 * tm-sun2.h, tm-sun3.h (STACK_END_ADDR): Use system include
4910 files to determine stack end address.
4912 * valarith.c (value_x_binop, value_x_unop): Change error message
4913 to be more useful. Pass proper argument to value_struct_elt.
4915 * valops.c (value_assign): FIXME comment that long long
4916 bitfields will break here.
4918 * Makefile.dist: Add symfile.h, remote-nindy.c, remote-eb.c.
4919 Update `make saber_gdb' to work better.
4921 * TODO: A woman's work is never done.
4923 * cplus-dem.c, environ.c, inferior.h, infrun.c, inftarg.c,
4924 main.c, obstack.c, printcmd.c, remote-eb.c, remote-nindy.c,
4925 remote-vx.c, remote.c, solib.c, source.c, sparc-pinsn.c,
4926 sparc-tdep.c, sparc-xdep.c, symmisc.c, symtab.c, symtab.h
4927 target.c, terminal.h, tm-sparc.h, tm-sunos.h, utils.c,
4928 valops.c, valprint.c, exec.c: Lint.
4931 Wed Dec 12 23:44:15 1990 John Gilmore (gnu at cygnus.com)
4933 Continuing Intel 960 port merge of GDB.
4935 * Makefile.dist: Merge i960 "nindy-share" files. Rename
4936 malloc.h to gmalloc.h to avoid name conflicts in /usr/include.
4937 Don't ship gdb.dvi in tar file. Link gdb with init.o, not init.c.
4938 Wack over "make depend" so it handles files in subdirectories
4939 vx-share, nindy-share, bfd, and in the current directory.
4941 * blockframe.c (get_prev_frame_info): Remove fatal error
4942 if stack not defined.
4944 * core.c (core_open, core_detach): New functions that handle
4945 the old "core-file" command as "target core" and "detach" instead.
4946 (core_file_command): Call them.
4947 (core_xfer_memory): Use common routine xfer_memory.
4949 * dbxread.c: Include a.out.gnu.h, not system a.out.h.
4950 dbxread now uses bfd for everything but symbol reading itself.
4951 BFD internals are used to drag out the relevant file offsets.
4952 (partial_symbol_file_open): Change args all around for BFD.
4954 * symtab.c: Rename "value" to "val" everywhere, so we can
4956 (symbol_file_command): New command, moved from dbxread.c
4957 and coffread.c. It uses BFD to read the file, then vectors
4958 based on its type, to dbx or coff symbol readers.
4959 * symtab.h: Extern a few vars for symbol_file_command.
4961 * target.h: Breakpoint takes a char * save area, not a char **.
4963 * valprint.c (val_print): When unpacking bitfields, offset
4964 the address in gdb of the value, if it is declared with a shorter
4965 type. Remove the last "runtime kludge test" of host byte order.
4967 * utils.c: Remove old my_bfd_read routine.
4969 * stack.c (frame_info): Use target_has_stack. Print program counter
4970 register's actual name rather than "pc", since it's called the
4971 "ip" (instruction pointer) on the i960 (sigh).
4973 * target.c (target_command): Add command for selecting a target
4974 type and calling its open routine. This is used for initiating
4975 communication with a particular target, in a generic way.
4977 * tm-i960.h: Update for modern gdb. Remove semicolons from
4978 various macros. Handle reading struct return convention, and
4979 error-out attempts to return structs with the "return" command.
4980 Be sure gdb doesn't think we know how to call functions in the
4983 * i960-tdep.c: Rename FRAME_CHAIN_VALID and FRAME_FIND_SAVED_REGS
4984 to i960_xxx in lower case.
4985 (arg_address): Circumvent errors due to LOC_ARG_BLOCK
4986 not being defined yet.
4988 * remote.c (remote_open): Call start_remote to initialize
4989 wait_for_inferior during open.
4990 (remote_xfer_inferior_memory): Return length written rather
4993 * remote-vx.c (target_command -> vx_open): Use new generic
4995 * remote-eb.c, inftarg.c, exec.c: ditto.
4997 * infrun.c: Fix comments.
4998 (attach_program -> child_open): Use new generic target command.
4999 (wait_for_inferior): Clear saved register values before target_wait,
5000 so target_wait can set some of them if convenient.
5002 * infptrace.c (fetch_inferior_registers, store_inferior_registers):
5003 Return success indicator, not void.
5004 (child_xfer_memory): Avoid fetching initial word if we'll
5005 overwrite it anyway.
5007 * infcmd.c (attach_command): Use new generic target open routine.
5008 (_initialize_infcmd): Update doc on attach and detach commands.
5009 (do_registers_info): Merge in a byte-order problem as a FIXME
5012 * findvar.c (find_saved_register): Avoid problem in current frame.
5013 (read_relative_register): Ditto.
5014 (write_register): Convert byte order on the way out.
5016 * exec.c (file_command): Add.
5017 (add_to_section_table, exec_command): Use new bfd_map_over_sections.
5018 (xfer_memory): Common function between core_xfer_memory and
5020 (exec_xfer_memory): Use it.
5022 * pn-opcode.h: Document that a "PN" is a Gould PowerNode.
5024 * breakpoint.c, breakpoint.h, symtab.h, value.h, frame.h, utils.c,
5025 valops.c, stack.c, target.c, sparc-xdep.c, source.c, printcmd.c,
5026 infcmd.c, i960-pinsn.c, eval.c, defs.h: lint and gcc -Wall.
5028 Sun Dec 2 16:45:06 1990 John Gilmore (gnu at cygnus.com)
5030 Merge Intel 960 port of gdb, continuing...
5032 * dbxread.c (partial_symbol_file_open, partial_symbol_file_read,
5033 symbol_file_command): Pass from_tty arg to hush 'em up.
5035 * coffread.c (symbol_file_command): Avoid output if from_tty != 1.
5036 Add magic numbers for 960 COFF format.
5038 Fri Nov 30 09:18:20 1990 John Gilmore (gnu at cygnus.com)
5040 Merge Intel 960 port of gdb, from Intel "1.2" release.
5042 CHANGE_LOG entries from their port, which was based on
5045 Thu Sep 6 11:02:22 PDT 1990
5046 Remove temp file if download is interrupted.
5048 Wed Aug 1 09:08:33 PDT 1990
5049 Now uses binary protocol to talk to NINDY.
5050 Old hex protocol (NINDY 2.13 and older) supported with -O switch.
5051 Times out after 5 seconds when trying to talk to NINDY.
5053 Tue May 29 12:54:49 PDT 1990
5054 Added variable baud rate (-b switch).
5055 Source code reorganization.
5057 Thu Apr 26 11:09:55 PDT 1990
5058 More cleanup of batch mode; specifically, execute "-s", "-e", and
5059 "-se" switches as soon as they are encountered on the invocation line.
5061 Fri Apr 20 13:47:15 PDT 1990
5064 Thu Apr 19 09:54:28 PDT 1990
5065 Add 'reset' command.
5067 Wed Apr 18 09:48:07 PDT 1990
5068 After opening remote tty, wait for 1 second to go by without input
5069 from it before trying to talk to NINDY (fixes problems with the
5070 Heurikon HK80/V960E).
5072 Mon Apr 4 16:33:05 PDT 1990
5073 Some output was not being suppressed in 'batch' mode.
5075 Thu Mar 22 15:31:11 PST 1990
5076 Ask user if old symbol table should be deleted when new file is
5079 Allow user to run a program downloaded before gdb960 was brought up.
5081 Correct "exec-file" help message for i80960 context.
5083 Correct bug in calculating user space address: could occasionally
5084 corrupt user program.
5086 Make sure to zero low-order bits in rip's because of bug in 960CA
5087 A-step part: could cause operation faults when "next"ing across
5090 Correct bug that made it impossible to get source line numbers for
5091 code loaded at addresses higher than 0x7fffffff.
5093 Wed Jan 10 12:43:22 PST 1990
5094 Open remote tty for exclusive use.
5096 Fri Jan 5 12:14:42 PST 1990
5097 Correct disassembly (CA manual was right after all):
5098 opcode for sysctl is 0x659
5100 Mon Oct 23 12:03:04 PDT 1989
5101 Use G960BASE and G960BIN environment variables to find 'sx' utility.
5103 Mon Oct 16 14:15:09 PDT 1989
5104 "sfr0"-"sfr31" should have been named "sf0"-"sf31"
5106 Mon Oct 2 15:56:31 PDT 1989
5108 Added 960CA disassembly support.
5110 To simplify maintenance:
5111 - eliminated use of symblic links on pinsn.c: use i960-pinsn.c
5113 - eliminated opcode.h: incorporates tables into i960-pinsn.c
5114 - moved 960-specific routines from i960-pinsn.c to i960-md.c
5115 - made disassembly interface identical to that in gdmp960.
5119 Wed Nov 28 21:32:48 1990 John Gilmore (gnu at cygint)
5121 * target.h: Allow targets to stack. Add target_has_memory,
5122 _registers, etc. Restructure memory access and "info files"
5123 to walk the target stack.
5124 * exec.c, core.c, inftarg.c, remote.c, remote-vx.c, remote-eb.c,
5125 target.c: Change tables to match target.h.
5126 * inflow.c (child_mourn_inferior): pop child_ops.
5127 (generic_mourn_inferior): Use new has_stack flag.
5128 * infptrace.c (child_xfer_memory): New memory regime.
5129 * inftarg.c (child_files_info): New "info files" regime.
5130 * remote-eb.c: New memory regime, new info files.
5131 * remote-vx.c: New memory regime, new info files. Now use
5132 separate targets for VxWorks attachment to machine, and
5133 actually running a process under VxWorks, since one has
5134 stack & execution & regs and the other doesn't.
5135 * remote.c: New memory regime, new info files.
5136 * sparc-xdep.c (fetch_core-registers): New memory regime.
5137 * target.c: New routines and support for stacked targets,
5138 new memory regime, new info files regime.
5141 Generalize section handling for an arbitrary number of sections,
5142 including use of the new BFD (binary file) library.
5143 * gdbcore.h: Add struct section_table.
5144 * exec.c (build_section_table): Iterate all sections and
5145 record what gdb needs to know about them.
5146 (exec_command): Use it.
5147 (exec_xfer_memory): Use the table.
5148 (exec_files_info): Print the table.
5149 * core.c (core_file_command, core_xfer_memory, core_files_info):
5151 * source.c (find_source_lines): Use bfd_get_mtime.
5152 * dbxread.c: Quick changes to make it compile with new BFD.
5153 * utils.c (error): Avoid using bfd_error in generic routines.
5155 * core.c (core_fetch_registers): Get from the ".regs" section of
5157 * sparc-xdep.c (fetch_core_registers): Use the .regs info.
5159 * inferior.h (attach_flag): Export.
5160 * infcmd.c (run_command): use new target_create_inferior.
5161 * infrun.c (child_create_inferior): Don't return result.
5162 * Makefile.dist (VERSION): 3.91.4.
5164 Fri Nov 23 28:15:38 1990 John Gilmore (gnu at cygint)
5166 * breakpoint.c (bpstat_num): Handle breakpoints which have
5167 since been deleted, such as temporary breakpoints.
5168 infcmd.c (program_info): ditto.
5170 * core.c (core_file_command): Display the frame where the core
5175 * remote-vx.c (target_command): Merge in target command from
5176 targ-vx.c. A few other cleanups.
5178 * TODO, Projects: Lots more stuff to do...
5180 Fri Nov 23 18:15:38 1990 John Gilmore (gnu at cygint)
5182 Massive changes to wall off the remote-debugging interface
5183 behind a function vector. The port to handle VxWorks targets
5184 is also part of this.
5186 All files: Replace references to renamed functions,
5187 remove references to remote_debugging, remove references to
5188 have_include_file, have_core_file in favor of target_has_stack,
5189 target_has_memory, etc.
5191 * Modularize the breakpoint interface.
5192 breakpoint.h (BREAKPOINT_MAX): New define sets max length of
5193 a breakpoint instruction.
5194 breakpoint.c: struct breakpoint's shadow_contents now sized as
5196 (insert_breakpoints): Vector to target to install breakpoints.
5197 (remove_breakpoints): Vector to target here too.
5198 Remove REMOTE_SA_SPARC kludges and other remote_debugging.
5199 sparc-tdep.c (single_step): Use new breakpoint interface for
5200 the single-step breakpoints.
5201 mem-break.c (memory_insert_breakpoint, memory_remove_breakpoint):
5202 New file, contains routines to insert and remove breakpoints by
5203 reading out the old contents and later replacing them. This is
5204 how ptrace breakpoints work, and many remote systems as well.
5206 * tm-vxworks68.h: New config file, overrides a few things for
5207 Wind River's preferences.
5209 * target.h: New file, for transfer vector used to talk to the
5210 inferior (child, attached, core, exec, remote, etc). All accesses
5211 to the thing being debugged should come through these vectors.
5212 target.c: New file, routines to handle transfer vector.
5213 (various files): Add transfer vectors XXX_ops for the various
5214 targets and pseudo-targets (core files, etc) we support.
5216 * breakpoint.c (bpstat_stop_status): Further explorations of
5217 watchpoints and why things don't work all the time.
5218 (bpstat_alloc): New fn to allocate a bpstat and chain it.
5220 * config.gdb: Only add "source ${srcdir}/.gdbinit" to
5221 the local gdbinit if it doesn't already have it.
5223 * core.c (core_ops): add and install.
5224 Allow core debugging without exec file.
5226 * dbxread.c (free_and_init_header_files): Merge two fns.
5227 (end_symtab): Free named symbol table when a new version comes in.
5228 (read_dbx_symtab): Relocate all kinds of symbols with base
5229 address. First step toward handling different text, data, bss
5231 (add_file_addr_command): Renamed add_file_command.
5232 (add_file_command): Vector to remote handler.
5233 Add "load" as an alias for "add-file" command.
5235 * defs.h: Allow "volatile" to be used in non-ANSI; use it for
5236 non-returning functions.
5238 * exec.c: Add exec_ops, and push it as a target when an exec
5241 * infcmd.c (run_command): Pass executable file name and arg list
5242 separately when starting an inferior. Permit "run" when no exec
5243 file is specified, for VxWorks.
5244 (detach_command): Move to child_detach in inftarg.c.
5246 * inftarg.c: New file. Unix-child-specific routines, and the
5247 child_ops structure.
5249 * inferior.h (registers): Export "registers" as the way for
5250 target dependent register handlers to find gdb's local copy of
5251 the registers. Rename "stop_after_attach" to "stop_soon_quietly"
5252 since it is now used by places that want wait_for_inferior to
5253 handle the grunge but want to see every trap from the inferior.
5255 * inflow.c (create_inferior): Pull out, and merge into infrun.c.
5256 Eliminate remote_debugging hooks in terminal handling.
5258 * infrun.c: Replace start_inferior with child_create_inferior.
5259 Move all the hair of Unix shells and ptrace idiosyncracies into
5260 child_create_inferior, so remote handlers don't have to deal.
5261 Remove running_in_shell. Rename stop_after_attach to
5262 stop_soon_quietly, and use it in a few other places where we want
5263 to just call wait_for_inferior and get control back on the first
5264 trap. trap_expected now never takes a value > 1.
5265 (init_wait_for_inferior): Initialize static vars when a new
5268 main.c (gdbinit): Add new hook for .gdbinit file name, let
5269 it be overridden by config files as GDBINIT_FILENAME.
5270 (DEFAULT_PROMPT): Add new hook for overriding (gdb) prompt.
5271 Both of these are used for VxWorks gdb.
5273 mcheck.c: rename include file "gmalloc.c" to avoid problems
5274 with system include file "malloc.c".
5276 param-no-tm.h: New include file, same as param.h but does not
5277 include the default "tm.h" file. This is used in files where
5278 the target is known, e.g. remote-eb.c or sparc-xdep.c.
5280 param.h: Now just a shell that includes tm.h and param-no-tm.h.
5282 remote-vx.c: New file, VxWorks remote debugging support. Uses
5283 RPC routines that are shared with the target system, in directory
5286 remote.c: Vectorize remote interface.
5288 source.c: Globalize source_path, and make an alias "l" for "list"
5289 since we now have the "load" command.
5291 sparc-xdep.c: Use new param-no-tm.h.
5293 symmisc.c (free_named_symtab): Add new function from Wind River.
5294 However, ifdef it out for now while we think about what it should
5297 tm-sun3.h, xm-sparc.h, xm-sun3.h, xm-symmetry.h: Move
5299 the xm- file, and change its name to CHILD_PREPARE_TO_STORE, since
5300 non-Unix-children handle this with their own code in the target
5303 Makefile.dist: Roll version to 3.92.3. Add vx-share stuff to
5304 source and target lists. Add vx-share to default list of include
5305 directories. Add new files to src and target lists: mem-break,
5306 target, inftarg, remote-eb, remote-vx, targ-vx. Be sure the
5307 ${srcdir} versions of munch and createtags are used.
5309 * valops.c (find_function_addr): Split out of call_function.
5310 (call_function_by_hand): Rename call_function; this function
5311 calls functions in the target by laboriously patching the target
5312 word-by-word with the right stack, args, regs, etc.
5315 Mon Nov 5 17:29:10 1990 John Gilmore (gnu at cygint)
5317 Handle AMD 29000 a bit better.
5319 * remote-eb.c (readchar): Mask received char log to make it readable.
5320 (remote_start): Pass arguments down to executing program.
5321 Make startaddr unsigned.
5322 infrun.c (start_inferior): Accept args, pass them to
5324 infcmd.c (run_command): Pass args down to start_inferior.
5326 * tconfig/am29k-aout, tconfig/am29k-coff: New files specifying
5327 the target object file format.
5328 tm-29k.h: Pay heed to COFF_ENCAPSULATE.
5330 * am29k-pinsn.c (print_insn): Print 0x on hex numbers in disassembly.
5331 am29k-tdep.c (examine_prologue): Better checking of function prefixes.
5333 Sun Oct 7 18:20:45 1990 John Gilmore (gnu at cygint)
5335 * Makefile.dist (VERSION): Roll version to 3.91.9 and freeze.
5336 * TODO: We did a few things, we have more to do though.
5338 * xm-sparc.h (CLEAR_DEFERRED_STORES): Define.
5339 * inflow.c (inferior_died): Clear deferred stores.
5341 * Debug problems with dummy frames and calls to the inferior.
5342 * tm-sparc.h (PUSH_DUMMY_FRAME, POP_FRAME): Move to sparc-tdep.c.
5343 * sparc-tdep.c (do_restore_insn): Simplify.
5344 (sparc_frame_find_saved_regs): Simplify and fix what we find.
5345 (sparc_push_dummy_frame): Simplify and fix what we push.
5346 (sparc_pop_frame): Slightly more hair here, deciding whether
5347 we are restoring a saved PC or returning to a return address in %i7.
5348 * sparc-xdep.c (read_inferior_registers): Debug if valid reg is read.
5350 * utils.c (xmalloc, xrealloc): Return type depends on __STDC__.
5351 * symtab.h (xmalloc): ditto, for obstack_chunk_alloc.
5352 * obstack.h (chunkfun): ditto.
5353 * defs.h (xmalloc, xrealloc): ditto
5355 * utils.c (quit): Grab the terminal from the child if necessary.
5357 * inflow.c (term_status_command): Rename to term_info, change
5360 * sparc-pinsn.c (print_insn): Disassembly prefers real instructions.
5361 (is_delayed_branch): Speed up.
5362 * sparc-opcode.h: Add ALIAS bit to aliases. Fix up opcode tables.
5363 Still missing some float ops, and needs testing.
5365 * Support for input and output radixes other than base 10
5366 * defs.h (input_radix, output_radix): Declare.
5367 * expread.y (yyparse, parse_number): Handle changes of input
5368 radix, and ambiguous names-or-numbers in radixes >10.
5369 * printcmd.c (print_scalar_formatted): Print formatted hex
5370 numbers in varying column widths.
5371 * valprint.c (val_print): Use output_format to print scalar ints.
5372 (set_input_radix, set_output_radix, set_radix): Create.
5373 (set_output_radix): Set output_format from output_radix.
5374 (_initialize_valprint): add `set radix' but leave the others off.
5376 * main.c (execute_command): Let stupid questions be turned off.
5377 (_initialize_main): Handle "set stupidity", etc.
5379 * main.c, inflow.c, inferior.h, frame.h, command.c, defs.h,
5380 sparc-pinsn.c, sparc-xdep.c, value.h, valops.c, values.c: Lint.
5382 Tue Oct 2 11:20:02 1990 John Gilmore (gnu at cygint)
5384 * TODO, Makefile.dist, ChangeLog: Freeze for 3.91.8 release.
5385 bfd stuff is still screwed up, but with some manual work, it
5388 * breakpoint.c (bpstat_do_actions): Start over if a command
5389 proceeds the inferior, since the inferior will have stopped and
5390 will need to have its new stop-actions taken care of.
5392 * dbxread.c (read_struct_type): Expression gives Sun3 4.0.3
5393 compiler fits, simplify it.
5395 * gdb.texinfo (directory command): Doc new dir command.
5396 source.c (directory_command): "dir" now puts things on the front
5397 of the path, moves dups up front, and handles multiple names
5398 on the command line, inserting each one in order. It also
5399 blows away cached line and full_filename info.
5401 * stack.c (backtrace_command): Skip "more stack frames follow"
5404 * Change #ifndef HAVE_VPRINTF to #define MISSING_VPRINTF in
5405 xm-convex.h, xm-hp300bsd.h, xm-isi.h, xm-merlin.h, xm-news.h,
5406 xm-np1.h, xm-pn.h, xm-pyr.h, xm-symmetry.h, xm-umax.h, xm-vax.h.
5407 The only odd one was Gould NP1, which had defined vprintf to
5410 * Merge Ted Goldstein <tedg@Eng.sun.com>'s changes for epoch.
5411 printcmd.c (print_command_1): Pass 'inspect' flag down as a global
5412 variable, inspect_it.
5413 valprint.c (print_string, val_print): Use the global inspect_it
5414 to indicate whether to print in Epoch style or normal style.
5416 Mon Oct 1 23:55:26 1990 John Gilmore (gnu at cygint)
5418 * printcmd.c (call_command): add an alias for the "print" command
5419 which runs expressions and doesn't print the result if void.
5420 (print_command_1): implement it.
5422 * command.c: Remove #if 0'd code. Initialize all the fields
5423 in add_cmd (). Rename do_nothing_command to
5424 not_just_help_class_command, and make it externally visible.
5425 command.h: add user_commands to struct.
5426 * main.c (define_command): Don't overload c->function with a char
5427 string as well as a function pointer.
5429 * eval.c (evaluate_subexp): Reinstall tiemann changes to
5430 calling convention of value_struct_elt () that got dropped in
5433 * tm-sparc.h (FRAME_FIND_SAVED_REGS): move to sparc-xdep.c.
5434 sparc-tdep.c (sparc_frame_find_saved_regs): ditto.
5436 * tm-sparc.h (POP_FRAME): replace some constants with defines.
5438 * sparc-xdep.c (store_inferior_registers): defer stores to regs
5439 until a good time (e.g. when we are about to run the child),
5440 saving ptrace calls.
5441 * infrun.c (proceed): handle DO_DEFERRED_STORES.
5442 * tm-sparc.h: define DO_DEFERRED_STORES.
5444 * sparc-xdep.c (store_inferior_registers): when storing float
5445 registers, don't store stack regs too. When storing the SP,
5446 however, DO store the stack regs too. This fixes a bug in which
5447 the dummy frame is not recognized when a call_function finishes,
5448 because its frame pointer (in the stack regs) was never
5450 (read_inferior_registers): Mark WIM and TBR and FPS and CPS valid
5451 even though we don't know how to read them from an inferior.
5452 valops.c (call_function): Comment about storing SP.
5454 * infrun.c (save_inferior_status): Save away the original bpstat
5455 chain so it can be restored later. Install the copied version for
5456 use by whoever saved the status. It will be blow away by
5457 restore_inferior_status, and the original chain restored. This is
5458 important for people who have pointers into the original.
5460 * breakpoint.c, command.h, copying.awk, dbxread.c, defs.h,
5461 findvar.c, frame.h, obstack.h, obstack.c, inflow.c, value.h,
5462 main.c, printcmd.c, sparc-tdep.c, symtab.c, valprint.c: lint
5465 Fri Sep 28 20:32:46 1990 John Gilmore (gnu at cygnus.com)
5467 * Makefile.dist: Roll version to 3.91.8. Add bfd.h and bfdconfig.h
5468 temporarily to the makefile. Add am29k-opcode.h and WHATS.NEW.
5469 Add stuff.c and kdb-start.c to the OTHERS list for tar files.
5471 Fri Sep 28 19:12:12 1990 John Gilmore (gnu at cygint)
5473 * Merge Mike Tiemann's multiple inheritance changes from Sun.
5474 Store the baseclasses in a type struct starting from array element
5475 0 rather than from the unusual array element 1.
5477 dbxread.c: the above.
5478 (virtual_context): Add
5479 Read new debug information about which virtual function table
5480 a virtual function is from, and store it in fn_field.fcontext.
5482 symtab.h: Add fcontextt. Fix baseclass indices. Typo in
5483 TYPE_FN_FIELD_STATIC_P.
5485 symtab.c: the above.
5486 valops.c: the above. Handle pointer casts of object *'s.
5487 (search_struct_method): Add.
5488 (value_struct_elt): First arg is now a pointer to a value, and is
5491 valprint.c: the above.
5492 values.c (value_virtual_fn_field): Add type arg. Handle
5493 offsetting to the proper object when calling virtual fns.
5495 (baseclass_addr): Add valuep arg.
5497 * README: Document the current state of BFD config (missing).
5498 * TODO, ChangeLog, Makefile.dist: Roll version.
5499 * WHATS.NEW: Add summary of changes since 3.5.
5501 Thu Sep 27 16:23:12 1990 John Gilmore (gnu at cygint)
5503 * dbxread.c (read_struct_type): Clear bit vectors whenever
5505 symtab.c (B_CLRALL): define.
5507 * tm-sparc.h (STORE_RETURN_VALUE): Avoid clobbering types by
5508 using == rather than =. Huh... This fixes the dreaded problem
5509 wherein builtin_type_int becomes TYPE_CODE_FLT.
5511 * core.c (info_files): Show the inferior pid.
5513 * config.gdb: Avoid putting "dir" command into .gdbinit. GDB
5514 already knows how to look in the source directory.
5516 * Remove psymtab hair from many places. Remove duplicated code
5517 for searching symbol tables. Hide psymtabs from most places.
5518 Make it fast to get from a psymtab to its symtab.
5520 blockframe.c (blockvector_for_pc): Remove psymtab hair.
5521 coffread.c (psymtab_to_symtab): Rename to psymtab_to_symtab2.
5522 mipsread.c (psymtab_to_symtab): Rename to psymtab_to_symtab2.
5523 dbxread.c: export psymtab_to_symtab, make it work if called N times.
5524 (psymtab_to_symtab): Rename to psymtab_to_symtab2. Initialize
5525 new symtab completely. New psymtabs get symtab pointer
5526 initialized to zero. Remove MI warning printf.
5527 symtab.h: Comments. Add psymtab to symtab pointer.
5528 (PSYMTAB_TO_SYMTAB): New macro.
5529 symtab.c: use PSYMTAB_TO_SYMTAB. Add psymtab_to_symtab and export it.
5530 source.c: use PSYMTAB_TO_SYMTAB. Remove symtab version and
5532 stack.c (backtrace_command): Avoid pre-pass to read symbols, if
5534 (print_frame_info): Avoid special-casing symbols that have not yet
5537 * source.c (open_source_file): Quick path if we have already
5538 located the source file by its full name.
5540 * symtab.c (lookup_symbol): Use find_pc_symtab rather than
5541 find_pc_psymtab. When a name is found in the misc function
5542 vector, search the symbol table for its mangled name, not the
5543 name that the user typed.
5545 * bfd.h: Fix missing comment terminators, make #endifs match.
5547 * valarith.c (value_less): Handle unsigned int comparisons.
5548 Add FIXME about pointer compares, which assume host and target
5549 pointers are the same.
5551 * command.c (do_nothing_command): lint
5552 dbxread.c: lint. Remove sort_syms. Document C++ visibility info,
5553 fix comments on debug symbol format for visibility. Actually set
5554 visibility of symbols.
5555 main.c (echo_command): lint; use <readline/history.h>.
5556 tm-sparc.h (FRAME_FIND_SAVED_REGS): lint
5557 obstack.h (_obstack_blank): Rearrange pointer math to avoid
5558 pointing past end of allocated memory; saber complains.
5559 obstack.h: Declare the external functions that we use.
5560 valarith.h: use <string.h>
5561 solib.c (solib_add): lint.
5563 Fri Sep 21 17:05:19 1990 John Gilmore (gnu at cygint)
5565 * main.c (initialize_main): Default info_verbose to off, now that
5566 symbol reading is fast.
5567 (quit_command): Avoid clobbering exec_bfd while quitting.
5569 * Initial BFD (binary file diddling library) merger:
5570 coffread.c: Change AOUTHDR to struct exe_hdr.
5572 core.c: initialize initialized data at compile time.
5573 (core_file_command): Move from coredep.c, convert to bfd.
5574 (xfer_core_file): Convert to bfd.
5575 exec.c (exec_file_command): use bfd routines.
5577 mips-tdep.c: Remove exec_file_command and friends.
5580 * coredep.c: (fetch_core_registers) Convert core_file_command to
5581 fetch_core_registers.
5582 mips-xdep.c, sparc-xdep.c, sun3-xdep.c: ditto.
5584 * utils.c: (error): Bogus crap, FIXME, to print bfd errors.
5585 (my_bfd_read): More bogosity, which I don't think we call.
5586 (program_name): Remove this atrocity asap!
5588 Wed Sep 19 13:36:41 1990 John Gilmore (gnu at cygint)
5591 values.c: allocate_repeat_value was not clearing the
5592 optimized_out field.
5593 (value_static_field): minor stylistic fix (wrong macro was used).
5594 valops.c (value_struct_elt_for_address): didn't work for C++
5597 * signame.c (_initialize_signame): Initialize signal names once.
5599 * breakpoint.h, command.c, copying.awk, defs.h, environ.c,
5600 exec.c, frame.h, infcmd.c, inferior.h, main.c, munch, sun3-xdep.c,
5601 symtab.h, tm-29k.h, valprint.c, value.h, values.c: Lint.
5603 * remote-eb.c: Support user-settable baud rates on the serial port.
5605 * tm-sun3.h (PREPARE_TO_STORE): fix typo.
5607 Fri Sep 14 13:28:29 1990 John Gilmore (gnu at cygint)
5609 * tconfig/sun3os4: Remove warning about native assembler,
5610 since it also occurs in the xconfig file.
5612 * findvar.c (registers): Allocate some slop after `registers'
5613 to prevent stray accesses from trashing the next variable.
5615 * tm-68k.h (REGISTER_BYTES): Allocate the right number of bytes
5616 on the sun-3, by changing the #ifdef from `sun3' (which is not
5617 defined by cc) to `sun'. Symptom was trashed builtin_type_XXX
5618 vars, which happened to follow `registers' in the executable.
5620 * readline/history.c (history_search): Heed gcc-2's advice
5621 and parenthesize && inside ||).
5623 * am29k-opcode.h, am29k-pinsn.c, am29k-tdep.c, remote-eb.c,
5624 tm-29k.c: Insert FSF copyright headers.
5626 * remote-eb.c: Better comments.
5628 * Makefile.dist: Update to 3.91.6.
5629 * TODO: note PREPARE_TO_STORE problem.
5631 Thu Sep 13 09:52:33 1990 Jim Kingdon (kingdon at cygint)
5633 * stack.c (frame_info): Only use FRAME_FIND_SAVED_REGS if defined.
5635 * remote.c: Wrap the whole file in #if !defined (SPECIAL_REMOTE).
5637 * infrun.c (wait_for_inferior, at end): Don't set up
5638 prev_* if the inferior no longer exists.
5640 * inferior.h (CALL_DUMMY_LOCATION): New macro, to replace
5641 CANNOT_EXECUTE_STACK.
5642 valops.c (call_function): Use it.
5644 * tm-convex.h: Add CALL_DUMMY_LENGTH for use by PC_IN_CALL_DUMMY.
5646 * inferior.h (PC_IN_CALL_DUMMY): New macro.
5647 infrun.c (wait_for_inferior, 2 places): Use it.
5649 * values.c (value_being_returned): Only use
5650 EXTRACT_STRUCT_VALUE_ADDRESS if defined.
5652 * Move PREPARE_TO_STORE from xm-sun3.h to tm-sun3.h to do the
5653 right thing for remote-eb.c.
5655 * sun3-xdep.c: Remove extraneous call to remote_store_registers.
5656 * sun386-xdep.c, hp300hpux-xdep.c, sparc-xdep.c: Ditto.
5658 * blockframe.c: Put get_frame_saved_regs inside #if !defined
5659 (FRAME_FIND_SAVED_REGS).
5661 * findvar.c ({fetch,store}_registers): Check for
5662 REMOTE_{FETCH_STORE}_REGISTER macro.
5664 * findvar.c (get_saved_register): Add argument lval and
5665 change meaning of argument addr.
5666 findvar.c: Change calls to get_saved_register to reflect
5667 new calling convention.
5668 valops.c (value_assign): Use get_saved_register instead of
5669 find_saved_register.
5671 Sun Sep 2 12:40:20 1990 Jim Kingdon (kingdon at cygint.cygnus.com)
5673 * coffread.c (read_one_sym): Make temp_aux an AUXENT, not
5674 an (uninitialized) pointer to one. Use "&" when passing it
5677 Fri Aug 31 22:57:54 1990 Jim Kingdon (kingdon at cygint.cygnus.com)
5679 * coffread.c (getfilename): Use DGUX x_offset and x_name if
5682 * coffread.c (symbol_file_command): Put semicolon after
5684 Put safe_to_init_tdesc_context in #if defined (TDESC).
5685 Put #ifdef TDESCs in 1st column for non-ANSI cpp's.
5686 coffread.c: #include <sys/stat.h>.
5687 (read_coff_symtab): Typo: in_source_files -> in_source_file.
5688 Add missing ')' in check for "lc%" and friends. Remove
5690 Declare read_one_sym() at top of file.
5691 (read_file_hdr): Put in extra #ifdefs so MC68MAGIC and
5692 MC68WRMAGIC can have the same value without causing a duplicate
5695 Thu Sep 13 15:55:36 1990 John Gilmore (gnu at cygint)
5697 * Allow a Makefile to be built without building the
5698 tm and xm file links that screw up builds in subdirectories.
5699 This is done with `config.gdb none', then you can do things
5700 like `make gdb.tar.Z'.
5701 * tconfig/none: Config file for no target system
5702 * xconfig/none: Config file for no host system
5703 * config.gdb: If no TM or XM files are called out by the
5704 host or target file, don't make links for them.
5706 * cplus-dem.c: Add documentation.
5708 * dbxread.c (read_ofile_symtab): Turn a fatal error into a
5709 simple error, so the user's gdb doesn't crash due to some object
5710 file problem (e.g. somebody is rebuilding the file out from under
5713 * printcmd.c (print_address_symbolic): demangle the symbol.
5715 * Makefile.dist (OTHERS): Remove tdesc-lib because it has
5716 Motorola copyrights in it. Make "make gdb.tar.Z" work.
5717 (alldeps.mak): sort and uniq all results from this; duplicates
5718 hose gdb.tar.Z link building. Remove RCS files from
5719 tconfig and xconfig. Add config files for sun386. Add
5720 a few odd files to OTHERS and HFILES.
5722 Mon Sep 10 21:20:24 1990 John Gilmore (gnu at cygint)
5724 * Makefile.dist: Pull solib.c to tconfig/sun?os4.
5725 Roll version number to 3.91.5. Make lint work in bindir.
5727 * README: Document cross-debugging and new file structure.
5729 * blockframe.c: Lint. Include "value.h" to declare read_register.
5730 (find_pc_partial_function): remove duplicate line.
5732 * command.h: Lint. Declare error_no_arg and dont_repeat.
5734 * tm-news.h: Remove inadvertently duplicated stuff.
5736 * mipsread.c: Remove cache_pc_function stuff, now done cleanly.
5737 Clean up usage of misc_function_type. Declare some CORE_ADDRs.
5739 * config.gdb: Allow `config.gdb host target' form. Clean
5740 up previous change that printed bogus messages when you just said
5743 * core.c: #include "command.h" for lint.
5746 * main.c: Remove some casts of enums. Lint.
5753 * printcmd.c (initialize_printcmd): Fix thinko in inspect cmd.
5755 * sparc-tdep.c (isannulled): Take instruction as parameter, don't
5756 read it from memory. This will allow us to save ptrace calls
5757 eventually. Changed caller single_step too.
5759 * sparc-xdep.c (fetch_inferior_registers): Avoid reading regs
5760 that we aren't going to use, saving many ptrace calls, especially
5761 when watchpointing or single stepping. Use some #define's for
5763 (store_inferior_registers): Ditto.
5764 (core_file_command): Use some #define's for constants.
5766 * tm-sparc.h: Add #define's for some register numbers, so we
5767 can eliminate the use of random constants in sparc-xdep.c.
5769 * stack.c (frame_command, print_frame_info, up_command,
5770 down_command) Remove frame_changed, since it
5771 causes a bug and doesn't seem to do anything useful. In some
5772 places it was used as a flag, in others as a stack level (?).
5774 * utils.c: Use MISSING_VPRINTF rather than HAVE_VPRINTF, so the
5775 default is to use the portable (vprintf) version rather than the
5777 * xm-news.h (MISSING_VPRINTF): Add.
5779 * valprint.c (val_print): Demangle fancy vtbl printouts. Lint.
5781 Sat Sep 8 00:24:12 1990 John Gilmore (gnu at cygint)
5783 * Remove stuff that forces -Bstatic linking of gdb, and warnings
5784 about linking debugged programs -Bstatic in the sun?os4 config
5785 files in tconfig and xconfig subdirectories.
5787 * main.c (main): Remove unreached exit(0) now that we exit
5790 * Create TODO file for online bug list. There are too many
5791 "little" bugs to keep track of on paper.
5793 * Change Projects file to refer to bug-gdb@cygnus.com
5794 rather than kingdon@ai.
5796 Fri Sep 7 23:35:15 1990 John Gilmore (gnu at cygint)
5798 * Makefile.dist (VERSION): 3.91.4 now.
5800 * symtab.c (init_misc_bunches): Rename from init_misc_functions.
5801 (condense_misc_bunches): Add sanity check that misc_count is
5802 the same as the number of symbols in the bunch.
5804 * coffread.c: rename init_misc_bunches. Pass an argument
5805 to condense_misc_bunches (a zero).
5807 * dbxread.c (partial_symbol_file_read): Call init_misc_bunches
5808 every time we are called; don't rely on our caller to do it.
5809 (add_file): Remove call to init_misc_bunches.
5811 * mipsread.c: Only warn, don't error, if unknown symbol types.
5812 This keeps an old gdb from falling on its face if it sees newly
5813 extended symbol info. Rename init_misc_bunches.
5815 Fri Sep 7 22:58:15 1990 John Gilmore (gnu at cygint)
5817 * Merge in changes from Per Bothner for DECstations and other
5818 MIPS stuff. The rest is Bothner speaking:
5820 The next message is a merger of Alessando Forin's mips port with
5821 mine. I've tried to use my good if biased judgment to get
5822 the best of both. It *does* need testing.
5824 Some of the changes are general, *not* mips-specific.
5827 Didn't believe in little-endian bit order.
5828 There are still inconsistencies about whether flags
5829 like BITS_BIG_ENDIAN are integer (#if ...) or
5830 boolean (#ifdef ...). I tried to paper over them.
5832 dbxread.c,coffread.c,mipsread.c,symtab.c,symtab.h:
5833 Moved some misc_function code that was common to
5834 {dbx,coff,mips}read.c to symtab.c.
5835 In the process, I think I cleaned things up a bit.
5836 At the same time, moved obsavestring and obconcat to symtab.c.
5839 Removed obsolete condense_addl_misc_bunches (use
5840 condense_misc_bunches(1) instead).
5843 Needed to include <sys/dir>, at least on DECstations.
5845 valops.c, mips-tdep.c, tm-mips.h:
5846 Added PUSH_ARGUMENTS macro to support funny argument-pushing
5847 conventions (when STACK_ALIGN is insufficient).
5848 Needed on mips, where doubles need 8-byte alignment,
5849 but ints only need 4.
5852 Removed cruft that was not being used.
5853 Merged in many fixes (most from Frank Yellin, fy@lucid.com).
5856 Print $ before register-names (I think that makes things a little
5858 Never print two instructions, even if one delays.
5859 Removed hex-disassemble set_cmd. (This is not mips-specific,
5860 so I think the argument is whether it is generally worthwhile or not.
5861 I'm inclined to think not, given how easy it is to
5862 convert between radixes in gdb.)
5865 This is basically Alessando's code.
5866 It doesn't use obstacks; I changed it to use obstacks
5867 in a few minor places where using malloc causes a
5868 memory leak. (Probably, more places could/should be changed.)
5869 I added record_misc_function where it was missing.
5870 In symbol_file_command and add_file_command, I tried
5871 to make the code consistent with more recent versions.
5872 Minor sylistic changes in parse_procedure.
5873 Make a .gdbinfo. psuedo-symbol point back to the real
5874 procedure symbol (using the isym field).
5877 This is basically from my port, but with a lot of details
5878 and a number of routines merged in from Alessando's version.
5879 I basically used my code "raw" backtrace (use heuristics
5880 from the actual code, rather than symbol table info) - though
5881 the idea is Alessandro's. I feel my code is a little cleaner
5882 here, particularly in being a little more flexible, such as being
5883 able to handle gcc-produced code (which it now can).
5884 It also doesn't do frame caching (which is not useful
5885 more recent gdb versions).
5886 I also used my code for push_/pop_dummy, more or less.
5887 I tried to incorporate AF's code for testing sigtramp
5888 while backtracing; I probably got it wrong.
5889 Added mips_print_register, which tries to scrunch as much
5890 information as possible on a screen...
5891 Removed the skip-prologue set_cmd. As with hex-disassemble (see
5892 under mips-pinsn.c), I don't see anything mips-specific here,
5893 and I don't see it being all that useful anyway.
5896 Added a $fp psuedo-reg distinct from $fp (nice for gcc).
5897 Use more register names (rather than hard-cases numbers).
5899 Thu Sep 6 18:33:15 1990 John Gilmore (gnu at cygint)
5901 * Hack up 3.90.11 changes:
5903 * Makefile.dist (depend): parameterize $(GCC).
5904 Add solib.c and solib.o.
5905 (readline): Fix vpath for both absolute or relative SRCDIR.
5907 * blockframe.c: Fix from Schaefer@asc.slb.com for shared libs.
5908 Also, let the part I didn't understand at least compile so
5909 I can test the rest. FIXME.
5911 * dbxread.c: Fix thinko using strcmp.
5912 (init_psymbol_list): declare static.
5913 (partial_symbol_file_open): Comment cleanups better, avoid
5914 cleaning up the string table since the caller will do that.
5915 Move the stat for mod time into symbol_file_command, temporarily.
5916 (There should be a mod time for each symbol file, eventually,
5917 to control its rereading. FIXME.)
5919 * infptrace.c (PT_WRITE_D): use same value as PT_WRITE_I for
5920 SunOS, which gives error for shared libs otherwise. (From
5921 Schaefer, probably FIXME needs work for portability.)
5923 * solib.c: Move #include "param.h" to work.
5924 Lowercase all the Uppercase Letters In the Messages.
5925 (find_solib): Clean up inferior_so_name for debug printouts.
5926 Allow no argument, to mean all shared libraries.
5928 * symmisc.c: include param.h to get CLEAR_SOLIB.
5930 Wed Sep 5 18:00:08 1990 John Gilmore (gnu at cygint)
5932 * Merge in Kingdon's changes from FSF: the diffs from 3.90.9
5933 to 3.90.11. ChangeLog entries below are from this.
5935 Wed Jun 13 09:17:39 1990 Jim Kingdon (kingdon at mole.ai.mit.edu)
5939 * Makefile.dist (HFILES): Add tm-sunos.h.
5941 Tue Jun 12 16:15:26 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5945 * Makefile.dist (gdb.tar.Z): Change linking of config so it works.
5947 Thu Jun 7 16:22:27 EDT 1990 Jay Fenlason (hack@ai.mit.edu)
5949 * sparc-opcode.h Added single-operand version of rett.
5951 Mon Jun 4 18:12:31 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5953 * m-sparc.h (REG_STRUCT_HAS_ADDR, STRUCT_ARG_SYM_GARBAGE):
5954 Put parens around gcc_p in expansion.
5956 Thu May 24 15:44:51 1990 Jim Kingdon (kingdon at mole.ai.mit.edu)
5958 * utils.c (lines_to_list): Return 10 if lines_per_page == 0.
5960 Wed May 23 16:36:04 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5962 * Changes for Sun shared libraries:
5963 blockframe.c (find_pc_partial_function): If a non-text symbol
5964 is found, set *address = pc - FUNCTION_START_OFFSET.
5965 breakpoint.c (insert_breakpoints) [DISABLE_UNSETTABLE_BREAK]:
5966 Disable breakpoints instead of giving an error.
5967 source.c (select_source_symtab): Initialize cs_pst.
5968 symmisc.c: Call CLEAR_SOLIB if defined.
5969 symtab.h: Make text{low,high} CORE_ADDR not int.
5970 (psymtab): New field addr.
5972 dbxread.c: Move DECLARE_FILE_HEADERS outside functions.
5973 (record_misc_function): Give correct type for N_DATA symbols.
5974 (condense_misc_bunches): do "misc_function_count = j" regardless
5976 Take code which is shared between symbol_file_command and
5977 add_file_command and put it into partial_symbol_file_{open,read}.
5978 Split add_file_command into add_file_command and add_file.
5979 Make psymtab_to_symtab read in the string table if the file
5981 Two new parameters to read_dbx_symtab and start_psymtab.
5982 tm-sunos.h: New file.
5984 Tue May 22 17:43:03 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5986 * infcmd.c: Change cont_command to continue_command and "cont"
5989 Mon May 21 14:41:41 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5991 * breakpoint.c (enable_breakpoint): Get value of watchpoint.
5993 * defs.h [sparc]: Use <alloca.h> regardless of __GNUC__.
5995 * values.c (USE_STRUCT_CONVENTION): Check for structures of
5996 size 1,2,4,8 rather than size < 8.
5998 * dbxread.c (dbx_lookup_type): Do f->length *= 2 as many times
5999 as necessary, not just once.
6001 * sparc-opcode.h: Add a bunch of new opcodes which Sun as supports.
6003 Thu May 17 15:04:09 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
6005 * {t,x}m-sun386.h, sun386-xdep.c, {x,t}config/sun386
6007 * tm-news.h: Add CALL_DUMMY_*.
6009 * tm-68k.h: Remove duplicate comment at FRAME_FIND_SAVED_REGS.
6011 * config.gdb: In list_host, list_target, use ${i}, not $i.
6013 Tue May 15 21:27:12 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
6015 * source.c (find_source_lines) [BROKEN_LARGE_ALLOCA]: Use xmalloc.
6017 * sparc-opcode.h: Change all store floating-point state register
6018 instructions to have the right match & lose fields.
6020 Sat May 5 12:39:18 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
6022 * Makefile.dist: Move -I${srcdir} to GLOBAL_CFLAGS and pass
6024 config.gdb: If srcdir != ., create readline directory and
6025 copy a makefile into it.
6027 * wait.h, infrun.c: Change WRETCODE to WEXITSTATUS for
6028 consistency with POSIX.
6030 * breakpoint.c (bpstat_stop_status): Disable watchpoint
6031 when we exit its exp_valid_block.
6033 Tue Sep 4 11:46:46 1990 John Gilmore (gnu at cygint)
6035 * Makefile.dist: Bump version to 3.91.3.
6037 * Clean up handling of breakpoint commands (somewhat).
6038 Prompted by Tiemann bug report "cont 10" doesn't work any more.
6040 inferior.h: Add breakpoint_proceeded to inferior status struct
6041 and globals; save it and restore it.
6042 (clear_breakpoint_commands): Cleanup, remove old #define.
6044 infrun.c (clear_proceed_status): Set breakpoint_proceeded.
6045 (save_inferior_status, restore_inferior_status): handle it also.
6046 (proceed): Remove earlier code that set breakpoint_proceeded.
6047 It is now set only in clear_proceed_status.
6048 (clear_proceed_status): Cleanup, use bpstat_clear rather
6049 than clear_breakpoint_commands. No callers need the stop_bpstat
6050 between clear_proceed_status and proceed.
6052 infcmd.c: Add breakpoint_proceeded definition and comment.
6053 (cont_command, jump_command, signal_command): Move call to
6054 clear_proceed_status right next to call to proceed.
6056 breakpoint.c (bpstat_do_actions): Avoid clobbering our
6057 caller's argument while running down the chain of breakpoints.
6058 Use new variable "breakpoint_proceeded" to determine when
6059 a command that it executes moves the inferior past the
6061 (bpstat_clear): Handle NULL argument.
6062 (bpstat_clear_actions): Avoid useless call to
6063 breakpoint_auto_delete.
6064 (delete_breakpoint): Clean up bpstat's that are pointing to
6065 the deleted breakpoint from the stop_bpstat chain.
6066 (breakpoint_auto_delete): Simplify.
6068 * Clean up handling of EOF, error on stdin, etc. This was
6069 prompted by a network problem that caused gdb to go into an
6070 infinite loop filling up its malloc'd memory.
6072 main.c (return_to_top_level): Cleanup: call bpstat_clear_actions,
6073 not clear_breakpoints_commands, which is now gone.
6074 (main): If command_loop returns (e.g. from EOF on stdin), do
6075 a quit_command (looping back to command_loop if quit_command
6076 doesn't really quit).
6077 (command_loop): check result from command_line_input and
6078 exit if it returns NULL, rather than passing the NULL to
6080 (gdb_readline): Free malloc'd result space before returning
6083 * utils.c (query): Handle C-d to mean "yes", just as if the
6084 input was not a terminal. Also avoid infinite loop if EOF
6085 occurs in mid-input-line before newline. This allows
6086 query to be used at EOF on stdin with reasonable results.
6088 * infrun.c (proceed): Set breakpoint_proceeded.
6090 * values.c (value_as_long): Avoid infinite recursion for enums.
6091 (_initialize_values): Fix typo in help msg (kingdon).
6093 * Makefile.dist (RL_LIB): Use RL_LIB_DEP for dependencies,
6094 RL_LIB for linking. This allows -lreadline for linking
6095 and nothing for dependencies, once readline is a real library.
6097 * config.gdb: Jim Kingdon: give useful error message if the
6098 host or target type is not recognized.
6100 * defs.h (alloca): SPARC <alloca.h> does not declare alloca,
6101 it just defines it. Dumb, but deal with it.
6103 * Jim Kingdon suggests:
6104 in xconfig/sun3os4, CFLAGS should be XM_CFLAGS.
6106 Wed Aug 29 18:03:27 1990 John Gilmore (gnu at cygint)
6108 * Makefile.dist (VERSION): Bump version # to 3.91.2.
6110 * Clean up Bothner's changes.
6112 * blockframe.c (clear_pc_function_cache): New function.
6113 * blockframe.c: remake cache_pc_function_* static.
6114 * dbxread.c (symbol_file_command): remove references to
6115 cache_pc_function_* variables.
6116 * dbxread.c (read_struct_type): Use VOFFSET_STATIC.
6117 * printcmd.c: Avoid kludging a global variable (addressprint)
6118 to avoid printing the address of a string twice. Instead,
6119 pass the format letter 's' down low enough that it can be seen
6120 to avoid this problem.
6121 (print_formatted): Pass format arg to value_print.
6122 (restore_addressprint): Remove function.
6123 (do_examine): Avoid hacking addressprint, cleanups and such.
6124 (print_frame_args): Add a comment to a Bothner change.
6125 * symtab.h: define VOFFSET_STATIC and use it instead of "-1".
6126 * symmisc.c (free_all_symtabs): Call clear_pc_function_cache
6127 to wipe out the values cached in blockframe.c.
6128 * symtab.c (find_method): Add comment saying how big you must
6129 allocate to be "big enough". Per being terse again.
6130 * valprint.c (val_print): Handle format letter "s" to print
6131 strings without addresses. Add comment to vtbl printing code
6132 which casts with wild abandon. Rearrange reference-printing
6134 @0xaddr: value (print w/addressprint)
6135 value (print w/~addressprint)
6136 @0xaddr (parameter lists w/addressprint)
6137 or nothing (parameter lists w/o addressprint)
6139 Tue Aug 28 10:47:18 1990 John Gilmore (gnu at cygint)
6141 * Merge more changes from Per Bothner:
6143 Gdb's handling of TYPE_CODE_REF was so counter-C++ (and otherwise
6144 annoying) that I tried to improve it. Here are my suggestions.
6146 These patches all attempt to handle TYPE_CODE_REF (as in C++) better.
6149 Do automatic de-reference when taking the address of a reference.
6151 Don't deref_ref when printing parameter lists.
6153 More attempts at treating refernences properly.
6155 In val_print, if deref_ref==0, don't print dangling " = ".
6157 Add COERCE_REF macro, which de-references an REF.
6159 * Merge changes from Per Bothner:
6161 * Fixed (Sony news)-specific configuration problems.
6162 * Fixed other problems with using vanilla pcc and libc (enum problems;
6163 assumption that vsprintf exists).
6164 * Some major speed-ups (finc_pc_partial_function now caches a match;
6165 parsing avoids duplicate symbol_lookup calls).
6166 * Changed handling of baseclasses (no longer use baseclasses field
6167 of struct type, use the first n_baseclasses fields instead).
6168 * Various minor changes/fixes, most C++-related.
6171 Cache the most previous match from find_pc_partial_function.
6172 (Save both low and high ends of matching function's pc range.)
6173 This speeds up the loop of infrun.c:wait_for_inferior quite
6174 a bit, and makes step/next commands much zippier.
6176 Added an enum->int cast (otherwise, some compilers barf).
6178 No longer set baseclass offset to 0, since multiple
6179 inheritance now mostly works.
6180 Added a number of casts, to shut up compiler warnings
6181 (after stabs where made enums, not ints).
6182 When discarding a symbol table (in symbol_file_command),
6183 must clear the cache introduced in blockframe.c.
6184 Don't convert $vtbl_ptr_type to vtbl any more.
6185 Get rid of TYPE_BASECLASEES and baseclass_vec (see also symtab.h).
6186 Mask off sign bit emitted by g++ for virtual table offset.
6187 Set voffset to -1 (not 1) for static member functions.
6189 Changed parsing/lexing of names to avoid doing symbol lookup twice
6190 (once when lexing to determine symbol class, once for real).
6191 Now only call symbol_lookup once. Fields of 'this' win especially big.
6193 Subpress printing addr twice in the case of 'x/s addr'.
6195 lookup_basetype_type is no longer used.
6196 Add find_methods as recursive helper function to decode_line_1.
6197 This allows multiple inheritance to work.
6198 Also, once one or more matches has been found, do not look in
6199 base-classes. (Baseclass methods would be overridden, anyway.)
6201 Removed baseclasses array in struct type.
6202 Instead of using baseclasses[i], use fields[i-1].
6203 Added virtual_field_bits[i] to indicate if the i'th baseclass is virtual.
6204 Changed sign convention of voffset (previous was inconsistent).
6206 Some macros (CALL_DUMMY and relatives) were missing. Put them back.
6208 Used to assume existence of vsprintf. Re-written to not need it
6209 if HAVE_VPRINTF is undefined.
6211 typecmp was too pessimistic. Made it less so.
6213 Don't print space after address.
6214 If vtable points to a misc symbol (with 0 offset), print it,
6215 since that indicates the actual class of the object.
6216 Changed ype_print_derivation_info to use new inheritance
6217 scheme (without baseclasses vector).
6219 In value_primitive_field, fixed some bugs left over from previous set of fixes.
6220 Also, changes needed because TYPE_BASECLASSES were removed.
6222 REGISTER_U_ADDR didn't work for PC. Rewrote to use an array.
6224 Tue Aug 21 20:08:54 1990 John Gilmore (gnu at cygint)
6227 If there is no path set, and the symbols don't indicate what directory
6228 a file was compiled in, look in the current directory. But either
6229 a path or a known compilation directory will prevent this.
6232 Three independent bug fixes:
6233 * Remove the #if 0 block that breaks some stuff.
6234 * SunOS 4.1 fixed the promoted-parameter-wrong-addr bug in Sun C;
6235 adapt gdb to either SunOS 4.0.* or 4.1.
6236 * MAX_OF_TYPE and MIN_OF_TYPE thinko. By tedg@sun, I think.
6239 Instantiate the class T when looking for methods in it. (Tiemann@sun)
6242 (type_print) Demangle the name being printed.
6243 (type_print_base) Handle botched demangling without coredump (tiemann).
6246 (check_stub_method): Document routine.
6247 (tiemann) fix bug for no-arg functions
6248 Avoid clobbering beyond end of malloc'd storage.
6249 Terminate the argument list properly.
6251 Sat Aug 18 01:29:59 1990 Per Bothner (bothner@cs.wisc.edu)
6253 * Changes merged by John Gilmore:
6256 In breakpoint_1, use new print_address_symbolic instead
6257 of find_pc_partial_function. (This forces use of assembler-level
6258 addresses, and avoids misleading non-mangled source-level names.)
6260 Generalize ansi argument such that -1 means skip arglist totally.
6261 Removed global variable print_ansi_qualifiers (which made
6262 code non-reentrant), in favor of extra explicit arguments
6263 to internal routines.
6265 Add new helper function print_address_symbolic.
6266 Use find_pc_misc_function instead of find_pc_partial_function
6267 (since we want assembler-level symbols here).
6269 Print unknown function as just "f (...)", not "f (...) (...)".
6270 Use new fputs_demangled explicitly.
6272 Fixed a typing violation (problem: value.h cannot be imported
6273 without renaming many variable in this file).
6274 lookup_symbol: If no matching misc_func, look for a C++-mangled name.
6275 decode_line_1: Moved forward some never-reached code.
6276 Made decode_line_2 skip function prologues correctly.
6278 fputs_filtered should not demangle by default.
6279 Add new fputs_demangled to demangle on demand..
6281 Change value_struct_elt to use value_primitive_field (using recursive
6282 utility function search_struct_field). This allows foo.bar to work
6283 for multiple inheritance (so far only for data fields).
6284 Change check_field in the same way (recursive helper function
6285 to support multiple inheritance).
6286 (Note: there are more of these problems that I haven't fixed.
6287 Any code that says TYPE_BASECLASS (t, 1) is probably wrong.)
6288 value_of_this: 'this' symbol name is now just "this", note "$this".
6290 Don't print static members.
6291 Avoid printing "members of <type>" if there are none.
6292 Simplified type_print_derivation_info by merging duplicate code.
6293 Remove useless blank lines in type_print_base (ptype command).
6295 Added declaration of new routine value_primitive_field.
6297 Added value_primitive_field which is generalized version of
6298 value_field that can handle multiple inheritance (non-zero offsets etc).
6299 Re-implemented value_field to call value_primitive_field.
6301 Fri Aug 17 23:33:44 1990 John Gilmore (gnu at cygint)
6303 * infcmd.c -- insert else to avoid 'delete env' coredump when you
6304 delete the whole environment. Karl Berry reported the bug.
6305 * source.c - fix openp to avoid //'s in filenames, which
6306 trigger an Emacs bug causing it to not be able to find files
6307 when running gdb in a window.
6308 * dbxread.c - zap the #if 0 that botches the add-file code.
6309 It seems to work a lot better without all the code commented out.
6311 Fri Jul 20 16:58:46 1990 John Gilmore (gnu at cygnus.com)
6313 * Merge Tiemann's and Ted Goldstein's changes, detailed below,
6316 Tue Jul 17 19:34:33 1990 Ted Goldstein (tedg at golem)
6318 * Makefile - added a ${CFLAGS} to a couple of entries,
6319 added remote-sa.sparc.c
6320 * added remote.sa-sparc.c, a modification of remote.c
6321 which conducts a dialog directly with the SparcStation prom.
6322 * breakpoint.c, infrun.c, sparcdep.c added
6323 remote_insert_breakpoint(), and remote_remove_breakpoint()
6324 to breakpoint.c instead of directly writing breakpoint instructions.
6325 * sparcdep.c on remote_debugging,there is no need
6326 to remove signle step breakpoint instructions.
6327 * main.c added "-epoch" flag and "int epoch_interface" to main.c
6329 * printcmd.c - epoch interface sends lisp expressions to open up
6330 epoch windows on inspection.
6331 * valprint.c - added arrayprint, and addressprint and made adding
6332 format controls easier
6333 * wait.h added a couple of undef's because we were getting
6334 complaints about WSTOPSIG and WTERMSIG begin redefined.
6337 Wed Jul 4 05:27:51 1990 Michael Tiemann (tiemann at masham)
6339 * symtab.c (decode_line_1): Add support for handling method stubs
6340 in the type information.
6342 Tue Jul 3 09:39:18 1990 Michael Tiemann (tiemann at masham)
6344 * values.c (baseclass_addr): Run loop from INDEX+1 to
6345 N_BASECLASSES; otherwise, we can still get into a loop.
6346 @@ This should be restructured to use a cleaner search strategy.
6348 Sun Jul 1 12:28:51 1990 Michael Tiemann (tiemann at masham)
6350 * dbxread.c (define_symbol,read_type): Grok GNU C++'s new
6351 abbreviation "Tt" for tags which have the same name as their
6354 Fri Jun 29 01:03:46 1990 Michael Tiemann (tiemann at masham)
6356 * symtab.c (list_symbols): add ability to set breakpoints on all
6357 the functions which match a particular regular expression.
6359 Tue Jun 26 04:26:29 1990 Michael Tiemann (tiemann at masham)
6361 * cplus-dem.c (cplus_demangle): New parameter ANSI says whether we
6362 should print ANSI qualifiers (such as `const' and `volatile').
6363 All callers changed to call with ANSI == 1, except from
6364 `check_method_stub', which uses old-style syntax.
6366 * symseg.h (struct fn_field): Remove unneccessary `args' field.
6367 * symtab.h (TYPE_FN_FIELD_ARGS): Redefined.
6369 * values.c (check_stub_method): New function.
6371 * cplus-dem.c (do_type): Handle "long long" (encoded as 'x').
6373 * dbxread.c (read_type): Handle new GNU C++ method type stubs.
6374 * valprint (type_print_base): Ditto.
6376 * symtab.c (gdb_mangle_typename): New function.
6378 Tue Jun 5 00:18:43 1990 Michael Tiemann (tiemann at gzilla)
6380 * breakpoint.c (catch_command): New function. Provides a
6381 mechanism to set breakpoints based on catch clauses.
6382 (disable_catch): Similar, but disables breakpoints on catch
6384 (delete_catch): Similar, but deleted breakpoints on catch clauses.
6386 Sun Jun 3 22:54:08 1990 Michael Tiemann (tiemann at gzilla)
6388 * blockframe.c (blockvector_for_pc): New function.
6389 * blockframe.c (block_for_pc): Changed to call
6390 `blockvector_for_pc' and get the block itself.
6392 * stack.c (catch_info): New function. Prints info about
6393 exceptions which can be caught in the current frame.
6394 * stack.c (print_frame_label_vars): New function. Similar to
6395 `print_frame_local_vars'.
6396 * stack.c (print_block_frame_labels): Prints out labels that are
